Section 6.6 Limitation. Payments of the Environmental Defect Values shall be made by Seller to Buyer as an adjustment to the Purchase Price at Closing if then determined or if not determined as of the Closing, thereafter, consistent with the time frames set forth above. Notwithstanding the provisions of Sections 6.2 and 6.3, no adjustment to the Purchase Price for Environmental Defect Values pursuant to Section 6.2(b) shall be made unless and until the aggregate value of all such Values (the "Aggregate Environmental Defect Value") 36 exceeds a deductible (not a threshold) equal to Five Hundred Thousand Dollars ($500,000.00). If the Environmental Defect Value with respect to any single Environmental Condition is less than $5,000, such cost shall not be considered in calculating the Aggregate Environmental Defect Value. In the event the Aggregate Environmental Defect Value exceeds ten percent (10%) of the Purchase Price, either Seller or Buyer may terminate this Agreement upon written notice to the other, and neither Party thereafter shall have any further rights or obligations hereunder. Section 6.7 Exclusive Remedies. The rights and remedies granted each Party in Part Six are exclusive rights and remedies against the other Party related to any Environmental Condition, or Losses related thereto and the other matters contained in this Part Six, and, EXCEPT AS PROVIDED IN PART 8, EACH PARTY EXPRESSLY WAIVES ANY AND ALL OTHER RIGHTS AND REMEDIES WHICH IT MAY HAVE AGAINST THE OTHER PARTY REGARDING ENVIRONMENTAL CONDITIONS, WHETHER FOR CONTRIBUTION, INDEMNITY OR OTHERWISE, REGARDLESS OF THE FAULT OR NEGLIGENCE OF THE CLAIMING PARTY, INCLUDING STRICT OR STATUTORY LIABILITY OF THAT PARTY UNDER ANY APPLICABLE LAW. PART SEVEN TITLE MATTERS Section 7.1 Confidentiality Agreement.

All information made available to Buyer and designated by Seller as confidential or proprietary shall be maintained confidential pursuant to the Confidentiality Agreement, which shall continue in force under its terms. Section 7.2 Preferential Purchase Rights. Seller shall have a period of sixty (60) days from the date of the Agreement to resolve preferential purchase rights to the Properties set forth on Schedule 7.2. To the extent any preferential purchase rights are exercised by any Third Person entitled to exercise such rights, or waivers thereof are not obtained prior to the Closing Date, then the Properties subject to such preferential purchase rights shall not be sold to Buyer and shall be excluded from the Agreement. The Purchase Price shall be adjusted by the dollar value allocated to the Properties subject to such preferential purchase right set forth in Schedule 2.3. In the event any Third Person initially elects to exercise a particular preferential right, but subsequently refuses or elects not to consummate the purchase under the 37 preferential right (whether such failure occurs before or after the Closing Date), the Parties agree that Buyer shall purchase such interests covered by the preferential right in accordance with the values set forth in Schedule 2.3 and the closing of such transaction shall take place on a date designated by Seller not more than ninety (90) days after the Closing Date. Section 7.3 Required Consents. If Seller shall fail to obtain any consent or waiver of maintenance of uniform interest provision required for the transfer of any Property, Seller's failure shall be handled as follows: (a) If the holder of the right to consent or party to a maintenance of uniform interest provision affirmatively refuses to consent or waive prior to Closing, such refusal shall be considered a Title Defect under this Part Seven and the Title Indemnity Payment therefore shall equal the value (or portion thereof) allocated to the affected Property (or portion thereof) in Schedule 2.3. (b) Except for approvals from Governmental Bodies normally received subsequent to assignment, if Seller believes a consent or waiver may be obtained subsequent to Closing, the Property shall be held by Seller for the benefit of Buyer after Closing and Seller shall provide Buyer with the economic benefits thereof until such consent or waiver is received or until ninety (90) days following Closing, if later, and Buyer shall pay for the Property at Closing in accordance with the Agreement as though the consent or waiver had been obtained. If Seller obtains the consent or waiver on or before ninety (90) days following Closing, then Seller shall deliver conveyances of the Property to Buyer. If the consent or waiver is not obtained or is affirmatively refused on or before ninety (90) days following Closing, Seller shall refund the value allocated to the affected portion of the Property to Buyer less any net revenues (revenues net of costs and Burdens) received by Buyer in connection with such affected portion of the Property and Seller's holding for the benefit of Buyer shall terminate. Section 7.4 Title Defects. Buyer shall notify Seller in writing of any Title Defects ("Title Defect Notice(s)") no later than 5:00 p.m. CDT on August 26, 2004. The Title Defect Notice shall state with reasonable specificity: (i) the Property affected; (ii) the particular Title Defect claimed; (iii) Buyer's good faith estimate of the amount the Title Defect reduces the value allocated to the affected Property on Schedule 2.3 (the "Defect Value"); and (iv) appropriate documentation substantiating Buyer's claim. Buyer shall conclusively be deemed to have waived any Title Defects not asserted by a Title Defect Notice no later than 5:00 p.m. CDT on August 26, 2004. For all Title Defects asserted in Title Defect Notices, Seller shall have the option of (a) curing the Title Defect, (b) contesting the Title Defect or Buyer's good faith estimate of the Defect Value, (c) paying Buyer's good faith estimate of the Defect Value as an adjustment to the Purchase Price subject to the limitations set forth below (a "Title Indemnity Payment"), or 38 (d) excluding the affected Property and reducing the Purchase Price by the value allocated to such Property. Seller shall notify Buyer in writing of its election no more than four (4) days following its receipt of a Title Defect Notice. Section 7.5 Seller's Right to Cure. If Seller elects to cure a Title Defect, then Seller shall so notify Buyer in writing within four (4) days after receipt of the particular Title Defect Notice ("Cure Notice"). Within sixty (60) days after receipt of the Title Defect Notice, Seller shall either cure the Title Defect to the reasonable satisfaction of Buyer ("Cure") or if Seller is unable to Cure such Title Defect, make a Title Indemnity Payment for such Title Defect equal to Buyer's good faith estimate of the Defect Value set forth in the Title Defect Notice. If Seller is unable to Cure a Title Defect prior to Closing, Seller shall convey the Property to Buyer and Buyer shall pay for the Property at Closing in accordance with the Agreement as though the Title Defect had been Cured, subject to Seller's obligation to make a Title Indemnity Payment to Buyer less any net revenues (revenues net of costs and Burdens) received by Buyer in connection with the affected portion of the Property if the Title Defect cannot be Cured during the sixty (60) days following receipt of the Title Defect Notice. Section 7.6 Contested Title Defects. If Seller contests the existence of a Title Defect or Buyer's good faith estimate of the Defect Value, then Seller shall so notify Buyer in writing no more than five (5) days after Seller's receipt of the Title Defect Notice ("Rejection Notice"). The Rejection Notice shall state with reasonable specificity the basis of Seller's rejection of the Title Defect or Buyer's good faith estimate of the Defect Value. Within thirty (30) days of Buyer's receipt of the Rejection Notice, representatives of Buyer and Seller, knowledgeable in title matters, shall meet and, within ten (10) days after Buyer's receipt of such Rejection Notice, either: (i) agree to mutually reject the particular Title Defect, or (ii) agree on the validity of such Title Defect and the Defect Value, in which case Seller shall have sixty (60) days after the date of such agreement within which to Cure such Title Defect and failing such Cure, to make the Title Indemnity Payment therefore. If the Parties cannot agree on either options (i) or (ii) in the preceding sentence, the Title Defect or the Defect Value subject to the Rejection Notice shall be submitted to arbitration in accordance with the procedures set forth in Section 10.13. If Seller fails to timely deliver a Rejection Notice or a Cure Notice, Seller shall be deemed to have accepted the validity of the Title Defect and Buyer's good faith estimate of the Defect Value, and shall pay Buyer a Title Indemnity Payment for the Title Defect equal to the Defect Value within sixty (60) days of Seller's receipt of the applicable Title Defect Notice. In the event a contested Title Defect cannot be resolved prior to Closing, Seller shall convey the affected Property to Buyer and Buyer shall pay for the Property at Closing in 39 accordance with the Agreement as though there were no Title Defect, subject to Seller's obligations as set forth in this Section 7.6 to Cure or to make a Title Indemnity Payment to Buyer less any net revenues (revenues net of costs and Burdens) received by Buyer in connection with the affected Property. Section 7.7 Title Indemnity Payments. Title Indemnity Payments shall be made by Seller to Buyer as an adjustment to the Purchase Price at Closing if then determined or if not determined as of the Closing, thereafter, consistent with the time frames set forth above Notwithstanding the provisions of Sections 7.3, 7.4, 7.5 and 7.6, Seller is obligated to make a Title Indemnity Payment only if the aggregate Defect Value of all Title Defects that Seller has agreed to pay pursuant to Section 7.4 or which is resolved pursuant to Section 7.6 (the "Aggregate Title Defect Value") exceed a deductible (not a threshold) equal to Five Hundred Thousand Dollars ($500,000.00). If the Defect Value for any single Property is less than $5,000, such value shall not be considered in calculating the Aggregate Title Defect Value. If a Defect Value is not liquidated or certain in amount, the Defect Value shall be the amount necessary to compensate Buyer for the adverse economic effect on the Property, taking into account all relevant factors, including without limitation, the Property's Allocated Value, the time value of money, the practical and legal effect of the Title Defect, and the amount of reduction in Net Revenue Interest or increase in the Working Interest of the affected Property. The aggregated Defect Value(s) for any Property shall never exceed the value allocated to such Property in Schedule 2.3. In the event the Aggregate Title Defect Value exceeds ten percent (10%) of the Purchase Price either Buyer or Seller may terminate this Agreement upon written notice to the other, and neither Party thereafter shall have any further rights or obligations hereunder. Section 7.8 Interest Additions. If Seller discovers an increase in the Net Revenue Interest shown on Schedule H with respect to a Property Interest which is free of Title Defects (an "Interest Addition"), then Seller shall, from time to time and without limitation, have the right to give Buyer written notice of such Interest Additions ("Interest Addition Notice"), as soon as practicable but no less than fifteen (15) days before Closing, stating with reasonable specificity the Property affected, the particular Interest Addition claimed, and Seller's good faith estimate of the amount the Additional Interest increases the value of the affected Property over and above the value allocated to such Property in Schedule 2.3 ("Interest Addition Value"). Seller shall conclusively be deemed to have waived any additional Interest not asserted by an Interest Addition Notice on or before fifteen (15) days prior to Closing. If Buyer agrees with the existence of the Additional Interest and Seller's good faith estimate of the Interest Addition Value, then the Interest Addition Value shall be applied as an offset to any Title Indemnity Payment required of Seller ("Offset"). If the Interest Addition Value exceeds the amount of any Title Indemnity Payment(s) due Buyer, the amount of such difference (an "Interest Addition Payment") shall be paid by Buyer to Seller as an adjustment 40 to the Purchase Price at Closing. If Buyer contests the existence of the Interest Addition or Seller's good faith estimate of the Interest Addition Value, then Buyer shall so notify Seller in writing within ten (10) days after Buyer's receipt of the Interest Addition Notice ("Interest Addition Rejection Notice"). The Interest Addition Rejection Notice shall state with reasonable specificity the basis of Buyer's rejection of the Additional Interest or Buyer's good faith estimate of the Interest Addition Value. Within ten (10) days of Seller's receipt of the Interest Addition Rejection Notice, representatives of Buyer and Seller, knowledgeable in title matters, shall meet and, within sixty (60) days after Seller's receipt of such Interest Addition Rejection Notice, either (a) agree to mutually reject the Interest Addition in which case Seller shall waive the Interest Addition, or (b) agree on validity of such Interest Addition and the Interest Addition Value, in which case Seller shall be entitled to an Offset or Interest Addition Payment. If the Parties cannot agree on either option (a) or (b) in the preceding sentence, the Interest Addition subject to the Interest Addition Rejection Notice shall be submitted to arbitration in accordance with the procedures set forth in Section 10.13. If Buyer fails to timely deliver an Interest Addition Rejection Notice, Buyer shall be deemed to have accepted the validity of the Interest Addition and Seller's good faith estimate of the Interest Addition Value, and Seller shall be entitled to an Offset or Interest Addition Payment as described above. Section 7.9 Reconveyance. If Seller makes a payment for Title Defect pursuant to Part Seven for one hundred percent (100%) of the Defect Value, Buyer shall, at Seller's sole option to be exercised no later than sixty (60) days after such payment, reconvey to Seller the Property or portion of the Property, and all proceeds accruing thereto, with respect to which the Title Indemnity Payment was made (effective as of the Effective Date). PART EIGHT INDEMNITY Section 8.1 General Indemnification. Buyer and Seller agree that: (a) Seller. Except with respect to Taxes (which are covered by Part Five), and title matters (which are covered by Part Seven) Seller shall indemnify, defend and hold harmless Buyer, its Affiliates and its and their respective officers, directors, agents and employees from and against all Losses based upon, arising out of, in connection with, or relating to: 41 (i) any breach of any representation, warranty, covenant or agreement of Seller contained in the Agreement; (ii) except for the Assumed Liabilities, any matter arising in connection with the ownership or operation of the Assets prior to the Effective Date; (iii) all actions, proceedings, claims, litigation, arbitration, mediation or other dispute resolution procedure pending or to the Actual Knowledge of Seller threatened, as of the Effective Date relating to or affecting the Assets; and for which Buyer has submitted a Claim Notice on or before December 31, 2005 in compliance with Section 8.2. NOTWITHSTANDING THE FOREGOING, SELLER'S FINANCIAL OBLIGATIONS UNDER THIS SECTION 8.1(a) SHALL NOT EXCEED, IN THE AGGREGATE, AN AMOUNT EQUAL TO FIFTY PERCENT (50%) OF THE PURCHASE PRICE AS ADJUSTED PURSUANT TO SECTION 2.2. (b) Buyer. Except with respect to Taxes (which are covered in Part Five), Buyer shall indemnify, defend and hold harmless Seller, its Affiliates and its and their respective officers, directors, agents and employees from and against all Losses based upon, arising out of, in connection with, or relating to: (i) any breach of any representation, warranty, covenant or agreement of Buyer contained in the Agreement; (ii) if the Closing occurs, any matter arising in connection with the ownership or operation of the Assets from and after the Effective Date; (iii) Buyer's inspection of the Assets as set forth in Section 3.2(g) and 4.1(a); (iv) if the Closing occurs, any dispute or claim arising after Closing in connection with preferential purchase rights on Assets conveyed to Buyer at the Closing; (v) any claims asserted by Third Persons against Seller in reliance on any interpretive data conveyed by Seller to Buyer, to the extent such claims arise as a consequence of Buyer's disclosure of such data; 42 (vi) If Closing occurs, Losses attributable to claims against Seller's bonds or similar instruments that remain in place after the Closing pursuant to Section 4.2; (vii) if the Closing occurs, the Assumed Liabilities; and (viii) any Losses not indemnified by Seller by reason of the limitations set forth in Section 8.1 (a). Section 8.2 Method of Asserting Claims, Etc. Except for Claims under Parts 5 and 7, all claims for indemnification under the Agreement shall be asserted and resolved as follows: (a) Third Party Claims. In the event that any claim for which a Party providing indemnification (the "Indemnifying Party") would be liable to a Party or any of its officers, directors, employees, agents, representatives or others entitled to indemnification hereunder (the "Indemnified Party") is asserted against or sought to be collected by a Third Person, the Indemnified Party shall promptly notify the Indemnifying Party of such claim, specifying the nature of such claim and the amount or the estimated amount thereof to the extent then feasible (which estimate shall not be conclusive of the final amount of such claim) (the "Claim Notice"). The Indemnified Party shall have thirty (30) days from its receipt of the Claim Notice (the "Notice Period") to notify the Indemnified Party (i) whether or not it disputes its liability to the Indemnifying Party hereunder with respect to such claim, and (ii) if it does not dispute such liability, whether or not it desires, at its sole cost and expense, to defend the Indemnified Party against such claim; provided, however, that the Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading which it shall deem necessary or appropriate to protect its interests. In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it does not dispute such liability and desires to defend against such claim or demand, then, except as hereinafter provided, the Indemnifying Party shall have the right to defend such claim or demand by appropriate proceedings, which proceedings shall be promptly settled or prosecuted to a final conclusion, in such a manner as to avoid any risk of the Indemnified Party becoming subject to liability. If the Indemnified Party desires to participate in, but not control, any such defense or settlement, it may do so at its own cost and expense. If the Indemnifying Party disputes its liability with respect to such claim, or elects not to defend against such claim, whether by not giving timely notice as provided above or otherwise, the Indemnified Party shall have the right 43 but not the obligation to defend against such claim, and the amount of any such claim, or if the same be contested by the Indemnifying Party or by the Indemnified Party, then that portion thereof as to which such defense is unsuccessful, shall be conclusively deemed to be a liability of the Indemnifying Party hereunder (subject, if it has timely disputed liability, to a determination in accordance with Section 10.13 that the disputed liability is covered by this Part Eight.) (b) Other Claims. In the event that the Indemnified Party shall have a claim against the Indemnifying Party hereunder which does not involve a claim or demand being asserted against or sought to be collected from it by a Third Person, the Indemnified Party shall promptly send a Claim Notice with respect to such claim to the Indemnifying Party. If the Indemnifying Party does not notify the Indemnified Party within the Notice Period that it disputes such claim, the amount of such claim shall be conclusively deemed a liability of the Indemnifying Party hereunder. Section 8.3 Payment. Payments under this Part Eight shall be made as follows: (a) Payment for Undisputed Amounts. In the event that the Indemnifying Party is required to make any payment under this Part Eight, the Indemnifying Party shall promptly pay the Indemnified Party the amount so determined. If there should be a dispute as to the amount or manner of determination of any indemnity obligation owed under Part Six or this Part Eight, the Indemnifying Party shall nevertheless pay when due such portion, if any, of the obligation as shall not be subject to dispute. The difference, if any, between the amount of the obligation ultimately determined as properly payable under Part Six or this Part Eight and the portion, if any theretofore paid, shall bear interest at the Agreed Rate as provided in Section 8.3(b). Upon the payment in full of any claim, the Indemnifying Party shall be subrogated to the rights of the Indemnified Party against any Person or other entity with respect to the subject matter of such claim. (b) Interest. If all or part of any indemnification obligation under the Agreement is not paid when due upon resolution of the claim, then the Indemnifying Party shall pay on demand to the Indemnified Party interest at the Agreed Rate on the unpaid amount of the obligation for each day from the date the amount became due until payment in full. 44 Section 8.4 Disputed Claims. If the Indemnifying Party shall notify the Indemnified Party during the Notice Period of any Disputed Claim under Section 8.2, the Disputed Claims shall be subject to the Dispute Resolution Procedure pursuant to Section 10.13.
