(a) "Sellers' Credits" shall equal the sum of the following: 12 (i) Sellers' share of the value of (A) all Inventory Hydrocarbons, such value to be based upon the price actually received for such Inventory Hydrocarbons (determined on a FIFO basis), less taxes, transportation and other fees deducted by the purchaser of such Hydrocarbons, such Hydrocarbons to be measured at the Effective Time by the operators of the Assets, and (B) the market value of the unsold inventory of gas plant products, if any, attributable to the Leases at the Effective Time allocable to Sellers' ownership; (ii) Sellers' share of the amount of all operating and capital expenditures (including overhead charged in the same manner as provided in the applicable joint operating agreement or in the absence of such agreement as customarily billed in the oil and gas industry) incurred and paid by Sellers and approved by Buyer pursuant to Section 9.1(a) attributable to the operation of the Assets during the Interim Period in accordance with generally accepted accounting principles. Such expenses and expenditures shall include, without limitation, royalties (excluding royalties on Inventory Hydrocarbons), rentals and other similar charges; expenses paid by any Seller to a third person under applicable joint operating agreements or other contracts or agreements included in the Assets, or in the absence of any joint operating agreement, those customarily billed under such agreement, including without limitation, drilling, completion, reworking, deepening, sidetracking, plugging and abandoning, geological and geophysical and land costs paid by or on behalf of such Seller in connection with the operation of the Assets which are attributable to the period of time after the Effective Time; ad valorem, property, production, excise, severance, and any other taxes (except income or franchise taxes) based upon or measured by the ownership of property or the production of Hydrocarbons or the receipt of proceeds therefrom; pro rata insurance premium costs after the Effective Time, including without limitation the costs to extend and/or cancel any coverages directly related to the Assets; and the costs of bonding and/or canceling bonding relating to the Assets after the Effective Time; (iii) An amount equal to any upward adjustment provided elsewhere in this Agreement or agreed between Sellers and Buyer in writing prior to or at Closing; and 13 (iv) An amount equal to the net volume due Sellers for gas imbalances which exist at the Effective Time, valued at $4.00 (four dollars) per thousand cubic feet of gas, such amount to be as shown in Schedule 4.1(g) updated to the Effective Time. (b) "Buyer's Credits" shall equal the sum of the following: (i) Sellers' share of the total sales value (for oil and condensate, to be valued at the prices actually received), before deduction of any royalties under the applicable pricing provisions of any oil, gas and gas plant liquids sales and processing agreements, of all Hydrocarbons produced and/or sold during the Interim Period which are attributable to the Assets and allocable to Sellers' ownership, and any other monies applicable to purchase or sales from the Assets on any wells during the Interim Period, but excepting interest income and income for overhead charged in the same manner as provided in the applicable joint operating agreement, regardless of whether or not payment has been received by Sellers; (ii) Sellers' share of the amount of all unpaid ad valorem, property, production, severance and similar taxes and assessments (but not including income or franchise taxes) based upon or measured by the ownership of property or the production of Hydrocarbons or the receipt of proceeds therefrom which taxes and assessments become due and payable or accrue to the Assets prior to the Effective Time, which amount shall, where possible, be computed based upon the tax rate and values applicable to the Tax Period in question; otherwise, the amount of the adjustment under this paragraph shall be computed based upon such taxes assessed against the applicable portion of the Assets for the immediately preceding Tax Period just ended; and (iii) An amount equal to the sum of any downward adjustments provided elsewhere in this Agreement or agreed between Sellers and Buyer in writing prior to or at Closing. 14 3.3 Sellers' Preliminary and Final Settlement Statements. At least three (3) business days prior to Closing, Sellers shall furnish Buyer with a good faith estimated accounting ("Preliminary Settlement Statement") showing the estimated amount of Sellers' Credits and the estimated amount of Buyer's Credits, subject to being finally adjusted within one hundred and twenty (120) days after the Closing as hereinafter provided. Within ninety (90) days after Closing, Sellers shall provide to Buyer, for Buyer's concurrence, an accounting ("Final Settlement Statement") of the actual amounts of Sellers' and Buyer's Credits for the adjustments as set out in Section 3.2. Buyer shall have the right for thirty (30) days after receipt of the Final Settlement Statement to review and take exceptions to such adjustments. If Buyer does not object to such Final Settlement Statement in writing within thirty (30) days after receipt, the Final Settlement Statement shall become final. Upon agreement of Sellers and Buyer as to the accuracy of the Final Settlement Statement or upon the expiration of such thirty (30) day period, whichever occurs first, Sellers or Buyer, as the case may be, shall promptly pay to the other such sum as may be found due, after making adjustments for any payments made at Closing (herein the "Final Settlement"). 3.4 Resolution of Disputes If Buyer and Sellers are unable to agree to all adjustments respecting the Final Settlement Statement within thirty (30) days after Buyer's receipt thereof, then adjustments which are not in dispute shall be made between Buyer and Sellers at the expiration of such thirty (30) day period. Any disagreements as to adjustments which remain in dispute shall be resolved on a good faith basis by Sellers and Buyer; provided, however, if Buyer and Sellers are unable, in good faith, to resolve such disagreements within forty-five (45) days after Buyer's receipt of the Final Settlement Statement, then the matters that remain in dispute shall be settled by reference to Grant Thornton LLP, Houston, Texas (the "Accounting Expert"), who shall resolve all determinations and adjustments with respect to allocating items to the period before or after the Effective Time in accordance with generally accepted accounting principles, consistently applied. The Accounting Expert shall render a decision resolving the matters in dispute within thirty (30) days following their submission to the Accounting Expert. The decision of the Accounting Expert shall be final and binding on the Parties. The fees and expenses of the Accounting Expert shall be shared equally by the Parties. 15 ARTICLE IV SELLERS' REPRESENTATIONS AND WARRANTIES 4.1 Sellers' Representations and Warranties.

If, prior to Closing, Buyer determines the existence of a "Title Defect" as defined in Section 7.2 below, Buyer shall notify Sellers in writing of any matter Buyer considers to be a Title Defect as soon as reasonably possible after such determination but, in any event, by not later than 5:00 p.m., Houston, Texas, time on October 10, 2003 (the "Defect Notice Date"). Such notice ("Notice of Title Defect") shall include (i) a specific description of the matter Buyer asserts as a Title Defect, (ii) a specific description of the Asset or portion of the Assets that is affected by the Title Defect, (iii) Buyer's calculation of the amount by which each Title Defect has diminished the value of the Assets, such amount to be determined by Buyer in good faith and in a commercially reasonable manner based on the allocation of the Purchase Price to the Assets as set forth on Schedule 3.1 hereto, and (iv) all necessary and desirable supporting documentation. Without prejudice to Sellers' special warranty of title specified in Section 7.4, which shall apply in any event, and subject to Sellers' representation and warranty specified in Section 4.1(i), which representation and warranty will not survive the Closing, Buyer shall be deemed to have waived any Title Defect which Buyer fails to assert in its Notice of Title Defect on or before the Defect Notice Date. 7.2 Title Defect. (a) The term "Title Defect" shall refer to any defect or deficiency in title to any Asset, except for Permitted Encumbrances, that (i) creates a lien, charge, contract, agreement, claim, encumbrance or other adverse claim, defect or deficiency affecting the value, use or ownership of any Seller in such Asset, (ii) diminishes any Seller's Net Revenue Interest from that set forth on Exhibits "A-1" through "A-5, (iii) increases any Seller's Working Interest from that set forth in Exhibits "A-1" through "A- 5" without a corresponding increase in Seller's Net Revenue Interest, or which creates an obligation to pay costs or expenses in an amount greater than such interest. No adjustment to the Purchase Price for Title Defects shall be made unless and until, and only to the extent that, (a) the value of such individual Title Defect exceeds $5,000.00 (five thousand dollars) in the case of a Title Defect relating to a Net Revenue Interest or a Working Interest and $25,000.00 (twenty-five thousand dollars) otherwise and (b) the aggregate value of all Title Defects exceeds 1.5% (one and one-half percent) of the Purchase Price. 26 (b) For purposes of this Agreement "Permitted Encumbrances" means: (i) lessor's royalties, non-participating royalties, overriding royalties, and division orders and sales and transportation contracts containing customary terms and provisions covering oil, gas or associated liquified or gaseous Hydrocarbons, reversionary interests, and similar burdens if the net cumulative effect of such burdens does not operate to reduce the Net Revenue Interest in any Asset to an amount less than the Net Revenue Interest set forth on Exhibits "A-1" through "A-5" or increase the Working Interest of any Asset from that set forth in Exhibits "A-1" through "A-5" without a corresponding increase in the Net Revenue Interest; (ii) subject to the provisions of Section 8.1 hereof, preferential rights to purchase and required non-governmental third party consents to assignments and similar agreements identified on Schedule 4.1(i) with respect to which prior to Closing (A) waivers or consents are obtained from the appropriate parties, or (B) the appropriate time period for asserting such rights has expired without an exercise of such rights; (iii) liens for taxes or assessments not yet due or delinquent or, if delinquent, that are being contested in good faith in the normal course of business; (iv) all rights to consent by, required notices to, filings with, or other actions by governmental entities in connection with the sale or conveyance of oil and gas leases or interests therein, if the same are customarily obtained subsequent to such sale or conveyance and Buyer and Sellers have no reason to believe they cannot be obtained; (v) such Title Defects as Buyer may have expressly waived in writing (it being understood and agreed that Buyer shall not be obligated to waive any defect); (vi) easements, rights-of way, servitudes, permits, surface leases and 27 other rights in respect of surface operations; provided they do not materially interfere with Buyer's operation or use of the Assets; (vii) defects, irregularities and deficiencies in title of or to any rights-of-way, easements, surface leases or other rights which do not materially impair the use of such rights-of-way, easements, surface leases or other rights for the purpose of which such rights will be held by Buyer; (viii) environmental laws and regulations applicable to the Assets; (ix) vendors', carriers', warehousemen's, repairmen's mechanics' workmen's, materialmen's, construction or other like liens arising by operation of law in the ordinary course of business or incident to the construction or improvement of any property in respect of obligations which are not yet due and, if due, which will be paid by Sellers prior to Closing; (x) all other liens, claims, charges, encumbrances, contracts, agreements, instruments, obligations, defects, and irregularities affecting the Assets, and/or which individually or in the aggregate are not such as to interfere with the operation, value, or use of any of the Assets, do not prevent Buyer from receiving the proceeds of production from the Assets, do not reduce the Net Revenue Interest of any of the Assets to less than the Net Revenue Interest set forth on Exhibits ""A-1" through "A-5" and do not obligate Buyer to bear costs and expenses relating to the maintenance, development, and operation of any of the interests in any amount greater than the Working Interest set forth on Exhibits "A-1" through "A-5" (unless the Net Revenue Interest for such Asset is greater than the Net Revenue Interest set forth in Exhibits "A-1" through "A- 5" in the same proportion as any increase in such Working Interest); and (xi) the Related Contracts to the extent that, with respect to an individual Related Contract, Sellers' representation and warranty in Section 4.1(h) with respect thereto is true and correct; provided, however, that, notwithstanding the foregoing, a Related Contract is not a Permitted Encumbrance (x) if it is not noted on Exhibits 28 "A-1" through "A-5" and (y) if and to the extent that it operates to reduce the Net Revenue Interest in any Asset to an amount less than the Net Revenue Interest set forth on Exhibits "A-1" through "A-5" or to increase the Working Interest of any Asset from that set forth on such Exhibits without a corresponding increase in the Net Revenue Interest. 7.3 Remedies for Title Defects. Subject to Section 7.2, the Purchase Price shall be reduced by the value of all Title Defects. Upon timely delivery by Buyer to Sellers of a Notice of Title Defect, Buyer and Sellers shall meet and use their commercially reasonable efforts to agree on the validity of the claim and the amount of any required Purchase Price adjustment. If the parties cannot agree on the amount of a Purchase Price adjustment, such amount shall be determined in accordance with the following guidelines: (a) If a Title Defect is based upon Buyer's notice that an interest discrepancy exists and Sellers owns a lesser Net Revenue Interest or is responsible for a greater Working Interest (without a corresponding and proportionate increase in the applicable Net Revenue Interest), or Sellers' interest is subject to reduction because of an undisclosed reversionary or "back-in" interest, then the Purchase Price shall be reduced. For each interest discrepancy, a report value reduction shall be calculated as follows. The report value reduction for a lease or property shall be calculated using the Netherland Sewell Reserve Report value at a discount rate of 10% for proved reserves of that Lease or property as the amount of present value of 10% attributed to the deficiency in interest. This report value reduction shall then be divided by the Netherland Sewell Reserve Report value for the proved reserves of the entire subject field to calculate a fraction reduction in field value. This fraction reduction in field value shall then be multiplied by the allocation of field value from Schedule 3.1 to calculate the reduction in Purchase Price. For differences in Net Revenue Interest or Working Interest in a Lease or property not included in the Netherland Sewell Reserve Report, if any, the Parties shall use their commercially reasonable efforts to agree on a mutually acceptable Purchase Price adjustment. (b) In the event a third party exercises an applicable preferential right of purchase, the Purchase Price shall be reduced by the allocated value of the affected Lease 29 or property or portion thereof on Schedule 3.1, and Closing shall occur as to the remainder of the Assets, if any. (c) If a Title Defect is a lien, encumbrance or other charge upon a Lease which is liquidated in amount, then the adjustment shall be the sum necessary to be paid to the obligee to remove the Title Defect from the affected Lease and Sellers shall pay such sum to the obligee on or before Closing. However, Sellers reserve the right, but not the obligation, to retain the obligation of this Title Defect and elect to challenge the validity of any such Title Defect or any portion thereof, and Buyer shall extend reasonable cooperation to Sellers in such efforts at no risk or expense to Buyer, and Sellers shall indemnify Buyer against any and all costs, expenses and losses relating to such Title Defect. If a Title Defect represents an obligation or burden upon the affected Lease for which the economic detriment to Buyer is not liquidated but can be estimated with reasonable certainty, the adjustment shall be the amount Sellers and Buyer mutually agree upon as necessary to compensate Buyer at Closing for the adverse economic effect which such Title Defect will have on the affected Lease and Buyer shall assume such Title Defect. (d) If Buyer is entitled to receive an adjustment for a Title Defect, as provided in this Agreement, Sellers shall have the right, but not the obligation, to attempt to cure the Title Defect and cancel the reduction in the Purchase Price if cured, by advising Buyer of such election within five (5) days of receipt of Buyer's Notice of Title Defect. If Sellers choose to cure the Title Defect, but have not done so by Closing, Sellers shall have the right to postpone Closing for a period not to exceed sixty (60) calendar days from the original Closing Date. (e) If the Parties cannot agree on the adjustment to the Purchase Price resulting from one or more Title Defects, then, assuming that all conditions to Closing shall have been satisfied or waived, then, without prejudice to either Party's rights hereunder, the Parties shall nevertheless proceed to Closing. In such event, Buyer shall at Closing deposit in an escrow account at a bank mutually agreed by the Parties the amount of the aggregate allocated values as shown on Schedule 3.1 of such Assets or portions thereof subject to such Title Defects. If the Parties have not been able to agree on the 30 value of the adjustment by the thirtieth (30th) business day after the Closing Date, then the Parties shall refer the matter for determination by a lawyer in Houston, Texas, who is qualified to render title opinions with respect to oil and gas properties and who is mutually acceptable to both Parties, who shall be instructed to resolve the matter within thirty (30) days after reference to him. Such lawyer may, if necessary, engage local counsel and an oil-and-gas economic expert to assist him in rendering his determination. Such lawyer's determination shall be final and binding on the Parties, and within five (5) days after such lawyer shall have issued his determination to the Parties, the Parties shall instruct the escrow agent to release funds accordingly. The fees and expenses of such lawyer and of the escrow agent shall be borne equally by the Parties. 7.4 Special Warranty of Title. SELLERS SHALL CONVEY SELLERS' INTERESTS SPECIFIED IN EXHIBITS "A-1" THROUGH "A-5" IN AND TO THE ASSETS TO BUYER WITHOUT ANY WARRANTY OF TITLE, EXPRESS OR IMPLIED, EXCEPT FOR SELLERS' SPECIAL WARRANTY BY, THROUGH AND UNDER SELLERS, BUT NOT OTHERWISE, AS PROVIDED IN THE FORMS OF ASSIGNMENT ATTACHED AS EXHIBITS "E", "F", "G", "H", "I", "J" AND "K" HERETO. Sellers' special title warranty above shall not cover those items expressly waived by Buyer in writing, and Buyer's sole remedy for any breach of Sellers' special title warranty shall be limited to that portion of the Purchase Price (without interest) allocated under Schedule 3.1 to the portion of the Assets affected by Sellers' breach of special title warranty. If there is no allocation under Schedule 3.1 for the portion of the Assets affected by Sellers' breach of special title warranty, the Parties shall use their commercially reasonable efforts to agree on the value of same. If the Parties cannot agree on such value within thirty (30) days, either Party may seek a judicial determination thereof in the courts of Harris County, Texas. 7.5 Notice of Environmental Defects. If, prior to Closing, Buyer determines the existence of an "Environmental Defect" as defined in Section 7.6 below, Buyer shall notify Sellers in writing of any matter Buyer considers to be an Environmental Defect as soon as reasonably possible after Buyer becomes aware of such Environmental Defect but, in any event, by not later than the Defect Notice Date. Such notice ("Notice of Environmental Defect") shall include (i) a specific description of the matter Buyer asserts as an Environmental Defect, (ii) a specific description of the Asset or portion of the Assets that is affected by the Environmental 31 Defect, (iii) Buyer's calculation of (x) the amount by which each Environmental Defect has diminished the value of the Assets and (y) the amount necessary to eliminate or resolve all Environmental Liabilities relating to such Environmental Defect, such amounts to be determined by Buyer in good faith and in a commercially reasonable manner (collectively, the "Environmental Defect Value"), and (iv) all necessary and desirable supporting documentation. Except for (i) the exclusions from Buyer's Assumed Environmental Obligations specified in Section 12.5(b) and (ii) Sellers' representation and warranty set forth in Section 4.1(p), which representation and warranty does not survive the Closing, Buyer shall be deemed to have waived any Environmental Defect which Buyer fails to assert in its Notice of Environmental Defect on or before the Defect Notice Date. 7.6 Environmental Defect. (a) The term "Environmental Defect" shall refer to (i) the failure of the Assets, or any of them, to be in material compliance with all applicable Environmental Laws; (ii) the Assets, or any of them, being subject to any agreements, consent orders, decrees or judgments based on any Environmental Laws that negatively and materially impact the future use of any portion of the Assets or that require any material change in the present conditions of any of the Assets; (iii) the Assets being subject to any material uncured notices of violations of or material noncompliance with any applicable Environmental Laws; or (iv) any matter that would constitute a breach or misstatement of Sellers' representation and warranty stated in Section 4.1(p) (without giving effect to the exception for the matters listed on Schedule 4.1(p)). No adjustment to the Purchase Price for Environmental Defects shall be made unless and until, and only to the extent that, (a) the value of such individual Environmental Defect exceeds $50,000.00 (fifty thousand dollars) and (b) the aggregate value of all such Environmental Defects exceeds 1.5% (one and one-half percent) of the Purchase Price. 7.7 Remedies for Environmental Defects. Sellers shall have the right, but not the obligation, to cure any Environmental Defect affecting the Assets. If an Environmental Defect is not cured to Buyer's reasonable satisfaction on or before the Closing Date, the Parties shall nevertheless proceed to Closing, and Buyer shall, at Sellers' option, but subject to the provisions of Section 7.6, either: 32 (a) acquire the Assets except for the Asset or Assets affected by the Environmental Defect or Defects, in which case the Purchase Price shall be reduced by the allocated value of the Asset or Assets as set forth on Schedule 3.1; or (b) accept the Asset or Assets affected by the Environmental Defect, and acquire all the Assets, in which case the Purchase Price shall be reduced by the Environmental Defect Value associated with such Environmental Defect. ARTICLE VIII PREFERENTIAL PURCHASE RIGHTS AND CONSENTS 8.1 Preferential Purchase Rights and Consents. (a) As provided in Section 4.1(l), certain preferential purchase rights or rights of approval or consent may exist with respect to the Leases under the agreements and Leases shown on Schedule 4.1(i). Sellers shall use reasonable efforts to notify all holders of (i) preferential rights, (ii) rights of consent to the assignment of the Assets (other than governmental consents, which are to be handled pursuant to Sections 17.1 and 17.2), or (iii) rights of approval of the assignment of the Assets, of its intention to sell the portion of the Assets affected thereby, and of the terms and conditions of this Agreement. Sellers shall not be liable to Buyer if any preferential rights are exercised, or any consents are denied, except as expressly provided in this Section 8.1. Sellers shall promptly notify Buyer if any preferential rights are exercised, any consents or approvals denied, or if the requisite period has elapsed without said rights having been exercised or consents or approvals having been received. If, prior to Closing, any such preferential rights are timely and properly exercised, the interest or part thereof so affected shall be eliminated from the Assets and the Purchase Price reduced by the portion of the Purchase Price allocated to such interest or part thereof as provided in Schedule 3.1. (b) If any additional third party preferential purchase rights are discovered after Closing, or if a third party preferential rights holder alleges improper notice, then Buyer agrees to cooperate with Sellers in giving effect to any such valid third party preferential 33 purchase rights which are binding on Buyer. In the event any such third party preferential purchase rights are validly exercised after Closing, Buyer's sole remedy against Sellers shall be the return by Sellers to Buyer of that portion of the Purchase Price (without interest) allocated under Schedule 3.1 to the portion of the Assets on which such rights are exercised and lost by Buyer to such third party, less the proceeds of production net of all expenses, capital expenditures, royalties, and costs of operations (including plugging and abandonment expenses but excluding mortgage interest and any burdens or encumbrances created by Buyer which shall be released prior to this payment) allocable to such interest, without interest. If there is no allocation under Schedule 3.1 for the portion of the Assets on which such rights are alleged or exercised, then the Parties shall use their commercially reasonable efforts to agree on the value of same to be returned to Buyer in the event it is lost to a third party. If the Parties cannot agree on such value within thirty (30) days, either Party may seek a judicial determination thereof in the courts of Harris County, Texas.

Buyer shall use its commercially reasonable endeavors to assist Sellers in this regard, including by causing appropriately senior and knowledgeable personnel of Buyer to accompany representatives of Sellers in conducting such process.

Sellers shall have no obligation to Buyer under this Section 12.5(b)(ii) for any matter for which they are not notified in writing by Buyer within twelve (12) months after Closing. It is agreed and understood, moreover, that this 51 exclusion and Sellers' indemnity obligations with respect to the same under this Agreement shall be limited only to Claims by third parties, including governmental agencies, against Buyer and/or Buyer's predecessors in interest with respect to the Assets.

ARTICLE XV CASUALTY LOSS AND CONDEMNATION 15.1 Casualty Loss. If, prior to the Closing, all or any portion of the Assets are destroyed by fire or other casualty or if any portion of the Assets shall be taken by condemnation or under the right of eminent domain (all of which are herein called "Casualty Loss" and limited to property damage or taking only), Sellers shall notify Buyer promptly after Sellers learn of such event. Sellers shall have the right, but not the obligation, to cure the Casualty Loss by repairing such damage or, in the case of personal property or fixtures, replacing them with equivalent items, no later than the Closing Date, all to Buyer's reasonable satisfaction. If any uncured Casualty Loss exist at the Closing, Buyer shall proceed with the purchase of such Assets, notwithstanding any such destruction or taking (without reduction of the Purchase Price) in which case Sellers shall, at the Closing, pay to Buyer all sums paid to Sellers by third parties (including underwriters and governmental agencies) by reason of the destruction or taking of such Assets and shall assign, transfer and set over unto Buyer all of the right, title and interest of Sellers in and to any Claims, causes of action, unpaid proceeds or other payments from third parties arising out of such destruction or taking.

The Parties agree that Sellers' actual damages would be difficult to determine and that such liquidated damages are a fair measure of Sellers' actual damages and are not a penalty. 16.2 Buyer's Remedies. Upon failure of Sellers to perform the obligations to be performed by Sellers prior to and on the Closing Date, as such Closing Date may be extended in accordance herewith, Buyer, at Buyer's sole option, may (a) enforce specific performance, or (b) terminate this Agreement, receive a return of the Performance Deposit and reimbursement for its actual out-of-pocket expenses incurred in connection herewith, and be entitled to receive from Sellers the amount of seventeen million five hundred thousand dollars ($17,500,000.00) as liquidated damages, all of which shall constitute Buyer's sole and exclusive remedies for such default, all other remedies (except as expressly retained in this Section 16.2 and in Section 16.4) being expressly waived and released by Buyer. The Parties agree that Buyer's actual damages would be difficult to determine and that such liquidated damages are a fair measure of Buyer's actual damages and are not a penalty. 16.3 Effect of Termination.

Notwithstanding the provisions of Sections 16.1, 16.2 and 16.3, termination of this Agreement shall not prejudice or impair Buyer's obligations under Sections 6.3 61 and 6.4 (and the confidentiality agreements referenced therein) and such other portions of this Agreement as are necessary to the enforcement and construction of Sections 6.3 and 6.4. 16.5 Performance Deposit If for any reason, except in the case of Section 16.1, the transaction contemplated by this Agreement does not close, Sellers shall return the Performance Deposit to Buyer. ARTICLE XVII MISCELLANEOUS 17.1 Certain Governmental Approvals. Buyer shall use its commercially reasonable efforts after Closing to obtain the unconditional approval by the MMS of (i) the Assignments of Record Title to Oil and Gas Lease(s) (Offshore) in the form attached hereto as Exhibit "E"; (ii) the Assignments of Oil and Gas Lease Operating Rights (Offshore) in the form attached hereto as Exhibit "F"; and (iii) the Assignments of Rights of Way (Offshore) in the form attached hereto as Exhibit "H". In the event Buyer or its nominated operator is elected successor operator under the operating agreements applicable to any of the Leases, Buyer also obligates itself to ensure that it or the successor operator makes application to the MMS to qualify as operator with respect to that portion of the Assets it will operate. Buyer shall take any actions reasonably required of it by the MMS or any other regulatory agencies to obtain all requisite regulatory approvals, including but not limited to, the purchase and posting of any and all bonds, supplemental bonds or other securities which may be required of it pursuant to OPA and 30 C.F.R Sections 250.7, 256.58, 256.59, and 256.61 in excess of any existing lease, pipeline or area-wide bond(s). Until the governmental approval with respect to an assignment described in this Section 17.1 is obtained, however, the following shall occur: (a) Sellers shall continue to hold the operating rights and record title to the applicable Assets as nominee for Buyer; (b) Buyer's indemnity under Section 13.3 shall include any and all claims, expenses of any kind or character relating to such Assets accruing after the Effective Time including but not limited to any bonding or regulatory costs incurred by Sellers; 62 (c) Sellers shall act as Buyer's nominee with respect to such Assets but shall be authorized to act only upon and in accordance with Buyer's specific written instructions, and Sellers shall have no authority, responsibility or discretion to perform any tasks or functions with respect to the Assets other than those which are purely administrative or ministerial in nature, unless otherwise specifically requested and authorized by Buyer in writing; and (d) Buyer shall continue to maintain and provide at its cost the insurance coverages with minimum limits of liability as set forth in Section 10.1(f) and (g) of this Agreement. If the MMS does not, within nine (9) months from the Closing Date, approve all (i) the Assignments of Record Title of the Leases (Offshore) into Buyer, (ii) the Assignments of Oil and Gas Lease Operating Rights (Offshore) into Buyer, and (iii) the Assignments of Rights of Way (Offshore) into Buyer, then: (w) As to those assignments that the MMS has approved, the transaction contemplated by this Agreement will proceed as to those Assets in accordance with the terms and conditions of this Agreement, mutatis mutandis; and (x) As to those assignments that the MMS has not approved, Sellers, at their option, may either: (i) continue to hold the operating rights, title to the Leases and the rights of way as Buyer's nominee, or, (ii) upon thirty (30) days notice to Buyer, rescind the purchase and sale of the Assets that are the subject of such non-approvals and terminate this Agreement as to those Assets, but only as to those Assets. (y) The exercise by Sellers of the option to rescind as specified in the preceding clause (x)(ii), however, shall be predicated upon Sellers' determination either (i) that Buyer 63 has failed to comply with the requirements of 30 C.F.R. Section 256.64 and not taken any and all actions required by MMS to obtain such approval, or (ii) there had been a Material Adverse Change to the financial condition of Buyer after Closing. (z) Upon such termination and rescission, this Agreement shall be null and void as between Buyer and Sellers with respect to the non-approved Assets, and (i) Buyer shall return to Sellers the assignments and any and all other documents, materials and data previously delivered to Buyer with respect to such Assets; and (ii) Sellers shall return to Buyer the Purchase Price allocated to such Assets in Schedule 3.1, without interest, less the proceeds of production net of all expenses, capital expenditures, royalties, and costs of operations (including plugging and abandonment expenses but excluding mortgage interest and any burdens or encumbrances created by Buyer which shall be released prior to this payment) attributable to the Leases and other rights from and after the Effective Time. In no event, however, shall Sellers ever be required to reimburse Buyer for any expenditures associated with workovers, recompletions, or the drilling, completion or plugging and abandonment of wells drilled or work performed by Buyer on or with respect to such Assets unless same were necessary to perpetuate the related Leases or operating rights or other rights. Sellers shall not be liable to Buyer if MMS approvals are not obtained, except as expressly provided in this Section 17.1. 17.2 Adequacy of Supplemental Bonds or Arrangements for the Pledge of Securities. Prior to execution hereof, Buyer shall confer with the MMS regarding the amounts and terms for the posting of supplemental bonds or pledge of securities pursuant to the provisions of 30 C.F.R Sections 256.61 and 250.7, and within a reasonable time of any MMS determination pursuant to such regulations, Buyer (directly or through its representative) shall satisfy the MMS requirements concerning same, including all financial responsibility requirements under OPA. 17.3 Special Offshore Interests The Parties acknowledge and agree that certain of the offshore Assets are in the nature of contract rights that are not recognized by the MMS as "record title" or "operating rights," and that, accordingly, the MMS will not approve, and the Parties do not expect the MMS to approve, the assignment of these interests from TEPI to Buyer. Buyer shall ensure nevertheless that the assignment documents relating to such interests are appropriately filed in the "non-required filing" system of the MMS. Such interests shall be excluded from the scope of 64 Section 17.1 for all purposes. 17.4 Louisiana Approvals The Parties acknowledge and agree that certain of the Leases onshore Louisiana involve the State of Louisiana as landowner and that, accordingly, the State of Louisiana must approve the assignment of such leases from the related Seller to Buyer. Buyer shall use its commercially reasonable efforts after Closing to obtain the approval of the State of Louisiana with respect to such assignments, and the provisions of Section 17.1 shall apply, mutatis mutandis, to such Leases and approvals. 17.5 Public Announcements. The Parties hereto agree that prior to making any public announcement or statement with respect to the transactions contemplated by this Agreement, the Party desiring to make such public announcement or statement shall consult with the other Party hereto and exercise its commercially reasonable efforts to (i) agree upon the text of a joint public announcement or statement to be made by both of such Parties or (ii) obtain approval of the other Party hereto to the text of a public announcement or statement to be made solely by Sellers or Buyer, as the case may be. Nothing contained in this Section shall be construed to require either Party to obtain approval of the other Party hereto to disclose information with respect to the transaction contemplated by this Agreement to any state or federal governmental authority or agency to the extent required by applicable law or by any applicable rules, regulations or orders of any governmental authority or agency having jurisdiction or necessary to comply with disclosure requirements of the New York Stock Exchange and applicable securities laws. 17.6 Filing and Recording of Assignments, etc. Buyer shall be solely responsible for all filings and recording of assignments and other documents related to the Assets and for all fees connected therewith, except as otherwise provided in this Agreement. Buyer shall furnish Sellers with copies of all filings made by it pursuant to this Agreement and of the pertinent recording data pertaining to same. Sellers shall not be responsible for any loss to Buyer because of Buyer's failure to file or record documents correctly or promptly. Buyer shall promptly file all appropriate forms or declarations with the MMS relative to this Agreement and its assumption of the Leases (and operations, if any Seller is currently the Operator and if Buyer becomes the operator), and Sellers shall cooperate with Buyer in connection with such filings. 65 17.7 Further Assurances and Records. (a) After the Closing, each of the Parties shall execute, acknowledge and deliver to the other such further instruments, and take such other action, as may be reasonably requested in order to more effectively assure to said Party all of the respective properties, rights, titles, interests, estates and privileges intended to be assigned, delivered or inuring to the benefit of such part in consummation of the transactions contemplated hereby. (b) Buyer agrees to maintain the files and records of Sellers that are acquired pursuant to this Agreement for a minimum of six (6) years after Closing. Buyer shall provide Sellers and its representatives reasonable access to and the right to copy such files and records for the purposes of (i) preparing and delivering any accounting provided for under this Agreement and adjusting, prorating and settling the charges and credits provided for in this Agreement, (ii) complying with any law, rule or regulation affecting Sellers' interest in the Assets prior to the Closing Date, (iii) preparing any audit of the books and records of any third party relating to Sellers' interest in the Assets prior to the Closing Date, or responding to any audit prepared by such third parties, (iv) preparing tax returns, (v) responding to or disputing any tax audit, or (vi) asserting, defending or otherwise dealing with any claim or dispute under this Agreement. (c) Buyer agree that, as soon as practicable after the Closing, Buyer shall remove or cause to be removed the names and marks used by Sellers and all variations and derivatives thereof and logos relating thereto from the Assets and shall not thereafter make any use whatsoever of such names, marks and logos.

Nothing herein expressed or implied is intended or shall be construed to confer upon or give to any person or entity (other than the Parties and their permitted successors and assigns) any rights or remedies under or by reason of this Agreement. 17.11 Governing Law. THIS AGREEMENT SHALL BE GOVERNED, CONSTRUED, AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAWS OTHERWISE 68 APPLICABLE TO SUCH DETERMINATIONS. 17.12 Exhibits.

Any of the terms, provisions, covenants, representations, warranties or conditions hereof may be waived only by a written instrument executed by the Party waiving compliance. Except as otherwise expressly provided in this Agreement, the failure of any Party at any time or times to require performance of any provisions hereof shall in no manner affect such Party's right to enforce the same. No waiver by any Party of any condition, or of the breach of any term, provision, covenant, representation or warranty contained in this Agreement, whether by conduct or otherwise, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such condition or breach or waiver of any other condition or of the breach of any other term, provision, covenant, representation or warranty. 69 17.16 Binding Effect; Assignment. (a) All the terms, provisions, covenants, obligations, indemnities, representations, warranties and conditions of this Agreement shall be enforceable by the Parties hereto and their respective permitted successors and assigns. Prior to Closing this Agreement may not be assigned or transferred to any other party, firm, corporation or other entity, without the prior, express and written consent of the other Party, and such consent may be withheld for any reason including convenience. After Closing, this Agreement may not be assigned except in connection with a sale, assignment, or other transfer of all or a portion of the Assets. In the event Buyer sells, transfers, or assigns all or a portion of the Assets, (i) this Agreement shall remain in effect between Buyer and Sellers as to all the Assets regardless of such assignment (and Buyer shall remain obligated hereunder), and (ii) Buyer shall require its successors and assigns to expressly assume its obligations under this Agreement, to the extent related or applicable to the Assets or portion thereof acquired by them. (b) Notwithstanding the foregoing, within seven (7) business days after the date of execution of this Agreement, Buyer may, by written notice to Sellers, designate one or more subsidiary entities to take title to some or all of the Assets. In such event each such subsidiary shall, at Closing, execute a joinder in agreement in the form of Exhibit "P" pursuant to which it agrees to become a party to this Agreement and expressly accepts and agrees to be bound by each of the terms, provisions, conditions, agreements, and indemnities of Buyer set forth herein. In no event shall the transfer of title to any designated subsidiary or the execution of any joinder in agreement by it pursuant to this provision relieve the Buyer of any of its obligations hereunder. 17.17 Taxes. (a) Apportionment of Ad Valorem and Property Taxes All ad valorem, real property taxes and personal property taxes, ("Property Taxes"), attributable to the Assets with respect to the tax assessment period ("Tax Period") during which the Effective Time occurs shall be apportioned as of the Effective Time between the Buyer and the Sellers, with the Sellers paying a fraction thereof based upon the number of days in the Tax Period prior to the Effective Time and the Buyer paying the balance thereof. The owner of record on the assessment date shall file or cause to be filed all required reports and returns incident 70 to the Property Taxes and shall pay or cause to be paid to all the taxing authorities all Property Taxes relating to the Tax Period during which the Effective Time occurs. If a Seller is the owner of record on the assessment date, then the Buyer shall pay to the Sellers Buyer's pro rata portion of Property Taxes within thirty (30) days after the receipt of the Sellers' invoice therefor, except to the extent taken into account as a purchase price adjustment pursuant to Section 3.2. If Buyer is the owner of record on the assessment date, then the Sellers shall pay to the Buyer Sellers' pro rata portion of Property Taxes within thirty (30) days after the receipt of the Buyer's invoice therefor, except to the extent taken into account as a purchase price adjustment pursuant to Section 3.2. (b) Sales Taxes. The Purchase Price provided hereunder excludes and the Buyer shall be liable for, any Transfer Taxes (as defined below) required to be paid in connection with the sale of the Assets pursuant to the Agreement. To the extent required by law, Sellers shall collect and remit any Transfer Taxes that are required to be paid as a result of the transfer of the Assets by Sellers to the Buyer. If the transfer of the Assets pursuant to this Agreement is exempt from any Transfer Taxes, Buyer shall, at Closing, provide the Sellers with properly executed exemption certificates or other documentation acceptable under applicable law. As used here, the term "Transfer Taxes" shall mean any sales, use, excise, stock, stamp, document, filing, recording, registration, authorization, and similar taxes, fees and charges. (c) Other Taxes. With the exception of income and franchise taxes, all other federal, state, and local taxes (including interest and penalties attributable thereto) on the ownership or operation of the Assets which are imposed with respect to periods or portions of periods prior to the Effective Time shall be paid by the Sellers and all such taxes imposed with respect to periods or portions of periods beginning on or after the Effective Time shall be paid by the Buyer. (d) IRS Form 8594. If the Buyer and the Sellers mutually agree that the filing of IRS Form 8594 is required, the Parties shall confer and cooperate in the preparation and filing of their respective forms to reflect a consistent reporting of the agreed upon allocation of the value of the Assets. 71 17.18 Gas Transportation/Processing. Following Closing, Buyer shall be responsible for the transportation and processing of oil and gas produced from the Assets. 17.19 Expenses of Sale. Except as otherwise specifically provided herein, each Party to this Agreement shall pay its own expenses (including without limitation, the fees and expenses of their respective agents, representatives, counsel and accountants) with respect to the negotiation, execution and the delivery of this Agreement and the consummation of the transactions under this Agreement. 17.20 Third Party Rights. Notwithstanding any other provision of this Agreement, this Agreement shall not create benefits on behalf of any person who is not a Party to this Agreement (including without limitation, any broker or finder, creditor or other person), and this Agreement shall be effective only as between the Parties hereto, their successors and permitted assigns. 17.21 Time Limits. Time is of the essence in this Agreement and all time limits shall be strictly construed and enforced. The failure or delay of any Party in the enforcement of the rights granted under this Agreement shall not constitute a waiver of said rights nor shall it be considered as a basis for estoppel. Except as otherwise limited by the time limits contained in this Agreement, such Party may exercise its rights under this Agreement despite any delay or failure to enforce the rights when the right or obligation arose. 17.22 Severance of Invalid Provisions. In case of a conflict between the provisions of this Agreement and the provisions of any applicable laws or regulations, the provisions of the laws or regulations shall govern over the provisions of this Agreement. If, for any reason and for so long as, any clause or provision of this Agreement is held by a court of competent jurisdiction to be illegal, invalid, unenforceable or unconscionable under any present or future law (or interpretation thereof), the remainder of this Agreement shall not be affected by such illegality or invalidity. Any such invalid provision shall be deemed severed from this Agreement as if this Agreement had been executed with the invalid provision eliminated. The surviving provisions of this Agreement shall remain in full force and effect unless the removal of the invalid provision destroys the legitimate purposes of this Agreement, in which event this Agreement shall be null and void. The Parties shall negotiate in good faith for any required modifications to this Agreement. 72 17.23 Construction of Ambiguity. In the event of any ambiguity in any of the terms or conditions of this Agreement, including any exhibits or schedules hereto and whether or not placed of record, such ambiguity shall not be construed for or against any party hereto on the basis that such party did or did not author the same.
