(c) The Investors, the Company and any other parties to the Transaction Documents intend to contract in strict compliance with applicable usury law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Transaction Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect (the "Maximum Lawful Rate"). Neither the Company, nor any Subsidiary, nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the Maximum Lawful Rate, and the provisions of this section shall control over all other provisions of the Transaction Documents which may be in conflict or apparent conflict herewith. The Investors expressly disavow any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Investor or any other holder of any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable law then in effect, then all sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Investor's or holder's option, promptly returned to the Company or the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the Maximum Lawful Rate, the Company and the Investors (and any other payors thereof) shall to the greatest extent permitted under applicable law, (i) characterize any non-principal payment as an expense, fee or premium rather than as interest, (ii) exclude voluntary prepayments and the effects thereof, and (iii) amortize, prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder. Notwithstanding anything to the contrary set forth in this Section 3.3 or Section 3.4, if a court of competent jurisdiction determines in a final order that the rate of interest payable hereunder exceeds the Maximum Lawful Rate, then so long as the Maximum Lawful Rate would be so exceeded, the rate of interest payable hereunder shall be 20 30 equal to the Maximum Lawful Rate; provided, however, that if at any time thereafter the rate of interest payable hereunder is less than the Maximum Lawful Rate, the Company shall continue to pay interest hereunder at the Maximum Lawful Rate until such time as the total interest received by the Investors, is equal to the total interest which would have been received had the interest rate payable hereunder been (but for the operation of this paragraph) the interest rate payable since the Closing Date as otherwise provided in this Agreement. Thereafter, interest hereunder shall be paid at the rate(s) of interest and in the manner provided in Section 3.3(a) and (b) and Section 3.4, unless and until the rate of interest again exceeds the Maximum Lawful Rate, and at that time this paragraph shall again apply. In no event shall the total interest received by any Investor pursuant to the terms hereof exceed the amount which such Investor could lawfully have received had the interest due hereunder been calculated for the full term hereof at the Maximum Lawful Rate. If the Maximum Lawful Rate is calculated pursuant to this paragraph, such interest shall be calculated at a daily rate equal to the Maximum Lawful Rate divided by the number of days in the year in which such calculation is made. As used in this section the term "applicable law" means the laws of the State of New York or the laws of the United States of America, whichever laws allow the greater interest, as such laws now exist or may be changed or amended or come into effect in the future. 3.4 INTEREST ON OVERDUE AMOUNTS. So long as any Event of Default shall have occurred and be continuing, the Company shall pay, in cash on demand from time to time, interest to the extent permitted by law on the Notes at a rate per annum equal to two percent (2%) above the Stated Rate. 3.5 MANDATORY PREPAYMENT. (a) Any and all principal of the Notes remaining unpaid, together with all interest accrued but unpaid thereon, automatically and unconditionally shall be due and payable in full in cash on the Final Maturity Date. (b) In the event of a Change of Control, each Investor shall have the option to require the Company to repurchase all the Notes held by such Investor at a purchase price in cash equal to the then outstanding principal amount of the Notes plus the Applicable Prepayment Premium, together with all interest accrued on such Notes through the date of repurchase. The Company shall give the Investors notice (a "CHANGE OF CONTROL NOTICE") of any transaction that would result in a Change of Control not less than thirty (30) days prior to the anticipated date of the consummation of such transaction (but in no event later than the third Business Day following the Company becoming aware thereof). Any Investor may exercise its right to require the Company to repurchase the Notes held by it by delivering written notice of such exercise (a "REPURCHASE NOTICE") to the Company within twenty (20) days after receipt of the Change of Control Notice. Within 15 days after the first date of receipt of a Repurchase Notice by the Company (the "REPURCHASE NOTICE DATE"), the Company shall give a notice to all other Investors advising them of the receipt by the Company of such Repurchase Notice, together with a copy of such Repurchase Notice. The date upon which the Company shall so advise such other Holders is herein called the "COMPANY NOTICE DATE". Within 15 days after the Company Notice Date, each such other Investor also may give a Repurchase Notice to the Company and each such Repurchase Notice shall be deemed given as of the date of the Repurchase Notice 21 31 given by the Investor initially exercising its repurchase rights hereunder. The repurchase of the Notes shall be consummated on a date selected by the Company upon at least 15 days' prior written notice to the Investors which have given the relevant Repurchase Notice(s), but in no event later than the date of consummation of such Change of Control or three (3) Business Days after the Company becomes aware of such Change of Control (the "REPURCHASE CLOSING DATE"). On the Repurchase Closing Date, the Company shall purchase from the Investors which have given such Repurchase Notice(s), and such Investor shall sell to the Company, the Notes held by such Investor for the purchase price specified in this paragraph (b). (c) In connection with any Change of Control, the Company covenants to (i) repay in full all Indebtedness under the Senior Credit Agreement and to terminate all commitments thereunder and to repay in full all other Senior Indebtedness the terms of which require repayment upon a Change of Control or offer to repay in full and terminate all commitments under all Indebtedness under the Senior Credit Agreement and all other such Senior Indebtedness or (ii) obtain the requisite consents under the Senior Credit Agreement and all other Senior Indebtedness to permit the repurchase of the Notes as provided in paragraph (b) above. 3.6 OPTIONAL PREPAYMENTS. (a) The Company may, at any time, at its option, prepay the Notes in whole and from time to time in part, upon not less than thirty (30) days' prior written notice to the Investors; provided, however, that each partial prepayment shall be in an aggregate principal amount not less than $1,000,000 or integral multiples of $100,000 in excess thereof. Each prepayment of the Notes shall include payment in cash of the principal amount of the Notes proposed to be prepaid on such prepayment date, all accrued but unpaid interest thereon to the date of such prepayment on the portion of the Notes being prepaid and the Applicable Prepayment Premium in respect of the portion of the Notes being prepaid. In the case of each partial prepayment of the Notes, the principal amount of the Notes to be prepaid shall be allocated pro rata among all of the Notes outstanding at such time in proportion, to the respective unpaid principal amounts. (b) Each notice of prepayment pursuant to this Section 3.6 shall specify the proposed date of such prepayment, the principal amount of the Notes to be prepaid, the interest owing on such principal amount and the aggregate Applicable Prepayment Premium in respect of the Notes being prepaid on such prepayment date. 3.7 SECURITIES REGISTER. (a) The Company shall cause to be kept at its principal office a register for the registration and transfer of the Notes (the "NOTE REGISTER"). The names and addresses of the holders of the Notes, the transfer of the Notes, and the names and addresses of the transferees of the Notes shall be registered in the Note Register. (b) The Person in whose name any registered Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes of this Agreement and the Company shall not be affected by any notice to the contrary, until due presentment of such Note for registration of transfer so provided in this Section 3.7(b). Payment of or on account of the 22 32 principal, premium, interest and any other amount paid on any registered Note shall be made to (or based upon the written order of) such registered holder. 3.8 LOST, ETC. SECURITIES. Upon receipt of evidence reasonably satisfactory to the Company (an affidavit of a financial institution or other institutional investor being satisfactory) of the ownership and the loss, theft, destruction or mutilation of any Note, and in the case of any such loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory to the Company (if such Investor is a financial institution or other institutional investor, its own agreement being satisfactory) or, in the case of any such mutilation, upon surrender for cancellation of such Note, the Company shall, without charge, issue, register and deliver in lieu of such Note a new Note of like kind representing the same rights represented by and dated the date of such lost, stolen, destroyed or mutilated Note. Any such new Note shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Note shall be at any time enforceable by any Person. 3.9 SEVERAL OBLIGATIONS; REMEDIES INDEPENDENT. No Investor shall have any obligation to any other Investor in respect of the failure by such Investor to purchase any Note required to be purchased by such Investor. The amounts payable by the Company at any time hereunder and under the Notes to each Investor shall be separate and independent debt and, subject to the provisions of Articles IX and XI, each holder shall be entitled to protect and enforce its rights arising out of this Agreement and the Notes held by it and it shall not be necessary for any other holder to consent to or be joined as an additional party in, any proceedings for such purposes.

Each of the Transaction Documents when executed and delivered by the Company, shall constitute a legal, valid and binding obligation of the Company enforceable in accordance with its terms, except insofar as the enforceability thereof may be limited (i) by applicable bankruptcy, insolvency, reorganization, moratorium or other similar laws affecting the enforcement of creditors' rights generally and (ii) by general principles of equity and public policy (regardless of whether considered at law or in equity). When issued and delivered to the Investors at the Closing upon payment therefor as provided in this Agreement, the Purchased Securities will be duly authorized, validly issued, fully paid and nonassessable and free and clear of any Liens created by the Company. 4.4 NO VIOLATION.

All consents, approvals, qualifications, orders or authorizations of, or filings with, any Governmental Authority required to be obtained by the Company, and all consents under any material contracts, agreements, or instruments by which the Company is bound or to which it is subject, and required in connection with the Company's valid execution, delivery, or performance of the Transaction Documents and the Enron Purchase Agreement, and the consummation of the transactions contemplated thereby, has been obtained or made other than the filing of a Form D with the SEC. 4.6 SEC DOCUMENTS AND FINANCIAL STATEMENTS. The Company has timely filed with the Commission all forms, reports, schedules, statements and other documents required to be filed by it since August 5, 1997 under the 24 34 Exchange or the Securities Act (such documents, as supplemented and amended since the time of filing, collectively, the "SEC DOCUMENTS"). The SEC Documents, including, without limitation, any financial statements or schedules included therein, at the time filed (and, in the case of registration statements, on the dates of effectiveness) (i) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and (ii) complied in all material respects with the applicable requirements of the Exchange Act and the Securities Act, as the case may be. The financial statements of the Company included in the SEC Documents at the time filed (and, in the case of registration statements, on the dates of effectiveness) complied as to form in all material respects with applicable accounting requirements and with the published rules and regulations of the Commission with respect thereto, were prepared in accordance with GAAP applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited statements, as permitted by Form 10-Q of the Commission), and fairly present (subject in the case of unaudited statements to normal, recurring audit adjustments) the combined financial position of the Company, as of the dates thereof and the combined results of operations and cash flows for the periods then ended.

To the knowledge of the Company, the estimates of reserves in the Reports were prepared in accordance with standard geological and engineering methods generally accepted in the oil and gas industry. The estimates of the lease operating expenses in the Reports reasonably reflect the historical experience of the Company and the Company has no reason to believe that the estimates will not reflect future lease operating expenses and the historical factual information supplied by the Company to the independent engineering firm in connection with the preparation of the Reports was, at the time of delivery to such firm, true and complete in all material respects. 4.8 NO MATERIAL ADVERSE EFFECT.

(c) In the event that, notwithstanding the foregoing, the Company or a trustee shall make any payment or distribution to the holders of Subordinated Obligations prohibited by the foregoing provisions of this Section 9.3, and if such fact shall have been known to the Investors, then such payment or distribution shall be deemed received by the Investors in trust for the benefit of the holders of Senior Indebtedness and shall promptly be paid over and delivered forthwith to the holders of such Senior Indebtedness or such other Person who is agent for the holders of such Senior Indebtedness.

(a) Subject to the prior payment in full in cash of all Senior Indebtedness, the holders of the Subordinated Obligations shall be subrogated to the extent of the payments or distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article (equally and ratably with the holders of all Indebtedness of the Company which by its express terms is subordinated to indebtedness of the Company to substantially the same extent as the Subordinated Obligations are subordinated and is entitled to like rights or subrogation) to the rights of the holders of such Senior Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal of (and premium, if any) and interest on the Subordinated Obligations shall be paid in full. For purposes of such subrogation, no payments or distributions to the holders of the Senior Indebtedness of any cash, property or securities to which the holders of the Subordinated Obligations would be entitled except for the provisions of this Article to the holders of Senior Indebtedness by the holders of the Subordinated Obligations, shall, as among the Company, its creditors other than holders of Senior Indebtedness and the holders of the Subordinated Obligations, be deemed to be a payment or distribution by the Company to or on account of the Senior Indebtedness. (b) If any payment by the Company in respect of Senior Indebtedness must be disgorged by any holder of Senior Indebtedness as a result of any action under the United States Bankruptcy Code or other debtor relief law, the obligations in respect of which such payment was made shall continue to constitute Senior Indebtedness and shall remain entitled to the benefit of the provisions of this Article IX. Without limitation of the foregoing, in the event of any such disgorgement by a holder of Senior Indebtedness, all holders of Subordinated Obligations, if any, who have become subrogated to the rights of such holder of Senior Indebtedness pursuant to this Section 9.5 and have obtained payment from the Company through the exercise of such subrogation rights shall disgorge and pay to such holder of Senior Indebtedness any payment so 55 65 obtained, to the extent of the payment or payments disgorged by such holders of Senior Indebtedness. 9.6 PROVISIONS SOLELY TO DEFINE RELATIVE RIGHTS.

(a) If any claim (a "THIRD PARTY CLAIM") is asserted against an Indemnified Person and such Indemnified Person intends to seek indemnification hereunder from the Company (the "INDEMNIFYING PERSON"), then such Indemnified Person shall give notice of the Third Party Claim to the Indemnifying Person as soon as practicable after the Indemnified Person has reason to believe that the Indemnifying Person will have an indemnification obligation with respect to such Third Party Claim and shall provide the Indemnifying Person with all papers served with respect to such Third Party Claim. Such notice shall describe in reasonable detail, to the extent known, the nature of the Third Party Claim, an estimate of the amount of damages attributable to the Third Party Claim and the basis of the Indemnified Person's request for indemnification under this Agreement. The failure of the Indemnified Person to so notify the Indemnifying Person of the Third Party Claim shall not relieve the Indemnifying Person from any duty to indemnify hereunder unless and to the extent that the Indemnifying Person demonstrates that the failure of the Indemnified Person to promptly notify it of such Third Party Claim prejudiced its ability to defend such Third Party Claim; provided, that the failure of the Indemnified Person to notify the Indemnifying Person shall not relieve the Indemnifying Person from any liability which it may have to the Indemnified Person otherwise than under this Agreement. Thereafter, the Indemnified Person shall deliver to the Indemnifying Person, within five business days after the Indemnified Person's receipt thereof, copies of all notices and documents (including court papers) received by the Indemnified Person relating to the Third Party Claim. 65 75 (b) The Indemnifying Person shall have the right to participate in, or assume control of, and the Indemnifying Person's insurance carrier shall have the right to participate in, the defense of the Third Party Claim at its own expense by giving prompt written notice to the Indemnified Person, using counsel of its choice reasonably acceptable to the Indemnified Person. If it elects to assume control of the defense of such Third Party Claim, the Indemnifying Person shall defend such Third Party Claim by promptly and vigorously prosecuting all appropriate proceedings to a final conclusion or settlement. After notice from the Indemnifying Person to the Indemnified Person of its election to assume the defense of such Third Party Claim, the Indemnified Person shall have the right to participate in the defense of the Third Party Claim using counsel of its choice, but the Indemnifying Person shall not be liable to the Indemnified Person hereunder for any legal or other expenses subsequently incurred by the Indemnified Person in connection with its participation in the defense thereof unless (i) the employment thereof has been specifically authorized in writing by the Indemnifying Person, (ii) the Indemnifying Person fails to assume the defense or diligently prosecute the Third Party Claim or (iii) there shall exist or develop a conflict that would ethically prohibit counsel to the Indemnifying Person from representing the Indemnified Person. If requested by the Indemnifying Person, the Indemnified Person agrees to cooperate with the Indemnifying Person and its counsel in contesting any Third Party Claim that the Indemnifying Person elects to contest, including the making of any related counterclaim against the Third Party asserting the Third Party Claim or any cross-complaint against any Person, in each case only if and to the extent that any such counterclaim or cross-complaint arises from the same actions or facts giving rise to the Third Party Claim. The Indemnifying Person shall have the right, acting in good faith and with due regard to the interests of the Indemnified Person, to control all decisions regarding the handling of the defense without the consent of the Indemnified Person, but shall not have the right to admit liability with respect to, or compromise, settle or discharge any Third Party Claim or consent to the entry of any judgment with respect to such Third Party Claim without the consent of the Indemnified Person, which consent shall not be unreasonably withheld, unless such settlement, compromise or consent includes an unconditional release of the Indemnified Person from all liability and obligations arising out of such Third Party Claim and which would not otherwise adversely affect the Indemnified Person. (c) If the Indemnifying Person fails to assume the defense of a Third Party Claim within thirty (30) days after receipt of written notice of the Third Party Claim, then the Indemnified Person shall have the right to defend the Third Party Claim by promptly and vigorously prosecuting all appropriate proceedings to a final conclusion or settlement. The Indemnifying Person shall have the right to participate in the defense of the Third Party Claim using counsel of its choice, but the Indemnified Person shall not be liable to the Indemnifying Person hereunder for any legal or other expenses incurred by the Indemnifying Person in connection with its participation in the defense thereof. If requested by the Indemnified Person, the Indemnifying Person agrees to cooperate with the Indemnified Person and its counsel in contesting any Third Party Claim that the Indemnified Person elects to contest, including the making of any related counterclaim against the Third Party asserting the Third Party Claim or any cross-complaint against any Person, in each case only if and to the extent that any such counterclaim or cross-complaint arises from the same actions or facts giving rise to the Third Party Claim. The Indemnified Person shall have the right, acting in good faith and with due regard to the interests of the Indemnifying Person, to control all decisions regarding the handling of the defense without the consent of the Indemnifying Person, but shall not have the right to 66 76 compromise or settle any Third Party Claim or consent to the entry of any judgment with respect to such Third Party Claim without the consent of the Indemnifying Person, which consent shall not be unreasonably withheld, unless such settlement, compromise or consent includes an unconditional release of the Indemnifying Person from all liability and obligations arising out of such Third Party Claim. 12.7 GOVERNING LAW. (a) THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE DOMESTIC LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO ANY CHOICE OR CONFLICT OF LAW PROVISION OR RULE (WHETHER IN THE STATE OF NEW YORK OR ANY OTHER JURISDICTION) THAT WOULD CAUSE THE APPLICATION OF THE LAWS OF ANY JURISDICTION OTHER THAN THE STATE OF NEW YORK. (b) THE PARTIES TO THIS AGREEMENT AGREE THAT JURISDICTION AND VENUE IN ANY ACTION BROUGHT BY ANY PARTY HERETO PURSUANT TO THIS AGREEMENT SHALL LIE IN ANY FEDERAL OR STATE COURT LOCATED IN THE STATE OF NEW YORK OR THE STATE OF TEXAS. BY EXECUTION AND DELIVERY OF THIS AGREEMENT, THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF SUCH COURTS FOR THEMSELVES AND IN RESPECT OF THEIR PROPERTY WITH RESPECT TO SUCH ACTION. THE PARTIES HERETO IRREVOCABLY AGREE THAT VENUE WOULD BE PROPER IN SUCH COURT, AND HEREBY WAIVE ANY OBJECTION THAT SUCH COURT IS AN IMPROPER OR INCONVENIENT FORUM FOR THE RESOLUTION OF SUCH ACTION. (c) THE COMPANY HEREBY AGREES THAT SERVICE UPON THEM BY REGISTERED OR CERTIFIED MAIL (RETURN RECEIPT REQUESTED) SHALL CONSTITUTE SUFFICIENT NOTICE. NOTHING HEREIN SHALL AFFECT THE RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR SHALL LIMIT THE RIGHT OF THE INVESTORS TO BRING PROCEEDINGS AGAINST THE COMPANY IN THE COURTS OF ANY OTHER JURISDICTION. (d) BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX FINANCIAL TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY, THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING BROUGHT TO ENFORCE OR DEFEND ANY RIGHTS OR REMEDIES UNDER THIS AGREEMENT, THE TRANSACTION DOCUMENTS OR ANY DOCUMENTS RELATED HERETO. 12.8 WAIVERS; AMENDMENTS. (a) No failure or delay of the Investors in exercising any power or right hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or 67 77 power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Investors hereunder are cumulative and not exclusive of any rights or remedies which they would otherwise have.
