2) all amounts due by Seller under any Contract that (i) are attributable to the ownership, operation or use of any Subject Interest before the Effective Time, (ii) are paid by Buyer and (iii) are identified by Buyer to Seller before Seller submits its Final Accounting Settlement under Section 1.6(a);

3) the amount of any overproduced gas position of Seller as described in Section 1.4(b);

4) the Downward Defect Adjustment;

5) the Allocated Amount of any Subject Interests deemed “Excluded Assets” under Section 4.10(a) (except as provided in and subject to Section 4.10(b);

6) any Purchase Price adjustment agreed to by the Buyer and Seller pursuant to the provisions of Section 5.2(b); and

7) all additional amounts mutually agreed to by Buyer and Seller.

1.4Gas Imbalances.

(a) The Parties recognize that the Gas Balancing Agreements described on Exhibit “L-1” hereto (which exhibit also references the amount of each Imbalance as of the Effective Time and the related underproduced parties and such Imbalances shall be referred to as the “Settlement Imbalances”) contain an Assignment of Interest provision (or similar provision) which granted to an underproduced party the option to demand either a cash settlement or the natural gas attributable to such overproduction (“Option”).

Seller and Buyer shall negotiate in good faith to resolve any disputes involving the Preliminary Accounting Statement. To the extent that the parties do not agree to any such amounts at or before Closing, such amounts shall be accounted for in, and in accordance with, the Final Accounting Settlement.

1.6Final Accounting Settlement.

4

Seller makes no warranty of title whatsoever; except that, upon and after Closing and subject to the provisions of Article 9 and the other provisions of this Agreement, Seller shall defend Buyer (up to, but not exceeding, the net revenue interest for such Subject Interest as listed on Exhibit “G” hereto and for no more than the Allocated Amount of such Subject Interest) against the lawful Claims of any Third Person claiming an interest (including but not limited to an encumbrance or lien) in a Subject Interest by, through or under Seller, except for any Claims arising out of, related to or in connection with one or more of the following: (a) by, through or under any Assignment, (b) for any Permitted Encumbrance, or (c) for a Title Defect asserted by Buyer pursuant to Section 4.2 hereof for which the Purchase Price is reduced, cured by Seller, or which does not meet the threshold in Section 4.7 hereof (“Special and Limited Title Warranty”).

4.5Disclaimer Regarding Lands.

(a) Buyer expressly acknowledges that Buyer is aware that the Lands are largely marsh lands, and there are numerous water covered areas within the boundaries of such lands, which may be susceptible to a claim by the State of Louisiana that the beds of such water covered areas are owned by the State of Louisiana as the beds of navigable water bodies. Seller does hereby exclude any contractual, implied or other warranty or representation regarding whether water covered areas are navigable or not navigable, and whether the beds of such water covered areas are owned by Seller or, alternatively, owned by the State of Louisiana;provided, however, nothing contained in these statements is intended to limit in any manner Buyer’s right to dispute any claim of ownership which may be asserted, in litigation or otherwise, by the State of Louisiana respecting any claim to the ownership of the beds of water covered areas, and Buyer’s right to assert that the beds of such water covered areas are owned in part by Buyer because such water covered areas are, in fact, not navigable.

(b) Buyer further acknowledges that Seller has made no representations or shall be making no warranties concerning the acreage content and/or depth restrictions of Seller’s interest in the Lands, regarding the location of the boundaries of the Lands, concerning any encroachments upon the Lands, regarding the existence of Seller’s rights in the Lands (including but not limited to the term(s) of Seller’s rights) and the application of the laws of liberative prescription thereto, and especially that Seller has made no representations or warranties concerning whether portions of the Lands may have eroded into or subsided beneath adjacent water covered areas (and hence such areas may have become subject to a claim of ownership by the State of Louisiana).

(c) Buyer agrees that if Buyer elects to sell or otherwise transfer the Lands (or any portion of the Lands), Buyer shall include in any such sale or transfer (or, alternatively, in any unrecorded purchase and sale agreement or similar agreement executed in connection with any such sale or transfer) provisions identical to the two preceding paragraphs, and Buyer shall protect, indemnify and hold Seller harmless from and against any and all claims, causes of action or liability arising as a result of Buyer’s failure to include such provisions in any further sale or other transfer by Buyer relating to the Lands (or any portion of the Lands).

15

4.6Title Defects.

(a) By written notice delivered to Seller during the Review Period (each such timely notice, a “Title Defect Notice”), Buyer may notify Seller of the existence of any matter that it reasonably believes constitutes a Title Defect. To constitute a proper Title Defect Notice, such notice must include with respect to each asserted Title Defect (1) the nature of, and a detailed legal explanation with respect to, such Title Defect, (2) a description of each Scheduled Interest affected, (3) the Allocated Amount of each such Scheduled Interest, (4) the amount by which Buyer believes such Allocated Amount has been reduced as a result of such Title Defect (which amount must comply with Section 4.8), (5) the computations and information upon which Buyer’s belief is based and (6) all supporting documentation reasonably necessary for Seller to verify Buyer’s computations and the existence and amount of such Title Defect.

(b) Buyer shall give Seller an opportunity to begin reviewing (and curing, if appropriate in Seller’s discretion) Title Defects as early as possible. Accordingly, if and when Buyer believes that a Title Defect may exist, Buyer shall, as soon as practicable, notify Seller of such possible Title Defect and furnish available information concerning such possible Title Defect and, from time to time thereafter as Buyer obtains more information, shall provide Seller, as soon as practicable, with such additional information.

4.7Seller’s Election to Cure.The (a) Downward Defect Adjustment (as determined in accordance with provisions of Section 4.8) for each Title Defect must exceed Fifty Thousand Dollars ($50,000.00) and (b) the aggregate of all such Downward Defect Adjustments (which satisfy subpart (a)) must exceed the sum of Three Hundred Thousand Dollars ($300,000.00) (which amount shall be a threshold, not a deductible) before there shall be any Purchase Price adjustment or further action required of Seller under this Section with respect to any Title Defect. As to any asserted Title Defect regardless of whether or not for which there is any reduction of the Purchase Price by virtue of the preceding sentence, for which Seller cures same, or for which there is an reduction in the Purchase Price; Seller shall have no further obligation with respect to such Title Defect and Buyer shall be deemed to have waived such Title Defect and the Subject Interest shall be conveyed to Buyer subject to such Title Defect.

As to each Scheduled Interest for which Buyer asserts an alleged Title Defect in a Title Defect Notice during the Review Period, the following provisions shall apply:

(a) If Seller agrees to the existence of a Title Defect, Seller may elect to cure any Title Defect. A Title Defect shall be deemed cured if Seller delivers to Buyer curative material that, in Buyer’s reasonable judgment, is sufficient to cure the Title Defect. Such material delivered by 5 p.m. on June 11, 2007 shall be deemed sufficient and acceptable to Buyer unless, prior to Closing, Seller receives from Buyer written notice that the curative is not acceptable including an explanation as to why it is not acceptable. Further, such materials delivered at or before the Closing shall be deemed sufficient and acceptable to Buyer if Seller does not receive from Buyer written notice as set forth above that the curative is not acceptable.

16

(b) If Seller agrees to the existence of a Title Defect and elects not to cure it or fails to cure it in accordance with the provisions of Section 4.7(a), the Purchase Price shall be reduced for any such Title Defect (i) provided that the agreed upon Downward Defect Adjustment (as determined in accordance with provisions of Section 4.8) for such Title Defect exceeds Fifty Thousand Dollars ($50,000.00) and (ii) the aggregate of all such Downward Defect Adjustments (which satisfy subpart (a)) exceeds the sum of Three Hundred Thousand Dollars ($300,000.00).

(c) At Closing, Seller may add to Exhibit “D” hereto any assignments or other agreements or instruments obtained, and any textual changes necessary, (a) to cure any Title Defect and (b) to reflect any newly added Excluded Assets under this Section.

4.8Downward Defect Adjustment.

(a) The value attributable to such uncured Title Defects (“Downward Defect Adjustment”) shall be determined as follows:

(1) Where Seller agrees with the value of the Title Defect as set forth in Buyer’s Title Defect Notice, that value shall be the value of the Title Defect.

(2) If the Title Defect is a lien, encumbrance or other charge upon the Scheduled Interest which is undisputed and liquidated in amount, then the Downward Defect Adjustment shall be the amount necessary to be paid to the obligee to remove the Title Defect from Buyer’s proportionate interest in the affected Schedule Interest; provided, however, that if the Title Defect affects more than Seller’s interest in the affected Scheduled Interest, then the value of the Title Defect will be reduced proportionately to the extent of Seller’s interest in the affected Scheduled Interest.

(3) If the Title Defect represents a uniform discrepancy for the entire Scheduled Interest for the life of same from the net revenue interest for any Asset stated on Exhibit “G”, then the Downward Defect Adjustment of such Title Defect shall be the product of the Allocated Amount of such Scheduled Interest on Exhibit “G” multiplied by a fraction, the numerator of which is the net revenue interest decrease and the denominator of which is the net revenue interest stated on Exhibit “G”.

(4) If the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the Scheduled Interest of a type not described in subsections (1), (2) or (3) above, the Downward Defect Adjustment of the Title Defect shall be

17

determined by taking into account the Allocated Amount of the Scheduled Interest so affected, the portion of the Scheduled Interest affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the affected Interest, and such other factors as are necessary to make a proper evaluation.

Buyer and Seller agree that in no event shall a Downward Defect Adjustment for a Scheduled Interest exceed the Allocated Amount thereof.

4.9Upward Adjustments.

(a) If not later than the Title Defect Date, either Seller or Buyer determines that there is any inaccuracy that results in Seller conveying or assigning to Buyer at Closing a net revenue interest in a Scheduled Interest which is higher than that reflected on Exhibit “G”, such Party shall, as soon as practicable, notify the other Party of such inaccuracy (an “Additional Interest”). This notice shall include: (i) a description of the affected Scheduled Interest (or interest therein or portion thereof); and (ii) a detailed description of the Additional Interest with supporting documentation. If Buyer agrees that the net revenue interest in such Scheduled Interest is higher and desires to purchase such Additional Interest, then the Purchase Price shall be adjusted as follows: in the event of the identification of an Additional Interest, Seller and Buyer shall endeavor in good faith to agree upon the amount of such increase in value occasioned by such inaccuracy which, for increases in net revenue interest, shall be based upon the proportionate increase in the net revenue interest multiplied by the Allocated Amount of such Scheduled Interests. The full amount of increased value attributable to the sum of the Additional Interest is called an “Upward Adjustment.” If Buyer does not desire to purchase the Additional Interest, then such Additional Interest shall be retained by Seller and be Excluded Assets. If necessary, the Parties shall enter into such additional agreements and instruments as are required to effect such exclusion of such Additional Interests from the transfer of the Assets. Notwithstanding anything in this Section 4.9(a) to the contrary, no Upward Adjustment shall be made to the Purchase Price if the corresponding Working Interest for the affected Scheduled Interest increases by an amount greater than the Additional Interest.

(b) The aggregate amount of Upward Adjustments under the preceding subsection (a) shall be applied to increase the Purchase Price pursuant to Section 1.3(a)(7).

4.10Preferential Rights. As promptly as practicable following execution of this Agreement, Seller shall send to the holder of each Preferential Right written notice offering to sell to such holder, in accordance with the contractual provisions applicable to such Preferential Right, such Subject Interest on the terms of this Agreement and for the total

18

Allocated Amount for such Subject Interest. Seller shall deliver to Buyer copies of all such notices and any responses thereto.

(a) If, before Closing, a holder of a Preferential Right notifies Seller that it intends to exercise its Preferential Right with respect to a Subject Interest to which the Preferential Right applies (as determined in accordance with the agreement in which the Preferential Right arises) or if the election period for a Preferential Right has not expired before Closing, then subject to Section 4.10(b), (i) the Subject Interest covered by the Preferential Right shall be deemed to constitute an “Excluded Asset” and shall be excluded from the Subject Interests to be conveyed to Buyer at Closing and (ii) the Purchase Price shall be reduced by the Allocated Amount of such Subject Interest.

(b) If, within 120 days following the Closing, the holder of the Preferential Right fails to exercise the Preferential Right within the election period thereunder, or fails to purchase the Subject Interest subject to the Preferential Right, Seller shall so notify Buyer. Within ten (10) Business Days after Buyer’s receipt of such notice, Seller shall sell to Buyer, and Buyer shall purchase from Seller, such Subject Interest under the terms of this Agreement for a price equal to the Allocated Amount thereof (and such Subject Interest shall not constitute an “Excluded Asset” by virtue of Section 4.10(a)).

4.11Consents to Assignment. As between Buyer and Seller, Seller shall be responsible for exercising reasonable efforts to obtain those necessary Consents which must be obtained prior to Closing and for giving all necessary notices of, assignment of the Subject Interests from Seller to Buyer. Nonetheless, before and following Closing, Buyer and Seller shall use commercially reasonable efforts (which efforts shall not require either to incur any monetary or non-monetary obligations) to obtain these consents and approvals required for, and in giving all notices of, the transfer of any Subject Interest to Buyer.

(a) If, before Closing, a Consent has not been obtained, satisfied or waived (if the parties mutually agree to such waiver), then subject to Sections 4.11(b) and (c), (i) the Subject Interest covered by the Consent shall be deemed to constitute an “Excluded Asset” and shall be excluded from the Subject Interests to be conveyed to Buyer at Closing and (ii) the Purchase Price shall be reduced by the Allocated Amount of such Subject Interest.

(b) If, within one hundred twenty (120) days following the Closing, the Consent is obtained or otherwise satisfied, Seller shall so notify Buyer. Within ten (10) Business Days after Buyer’s receipt of such notice, Seller shall sell to Buyer, and Buyer shall purchase from Seller, such Subject Interest under the terms of this Agreement for a price equal to the Allocated Amount thereof (and such Subject Interest shall no longer constitute an “Excluded Asset” by virtue of Section 4.11(a)).

19

(c) For any Subject Interest as to which Buyer waives the obtaining of a Consent at or before Closing, (i) such Subject Interest shall not constitute an “Excluded Asset”; (ii) the Purchase Price shall not be reduced for any reason related to such Consent; and (iii) notwithstanding anything to the contrary, Buyer shall indemnify, protect, defend and hold Seller, each prior owner of the Subject Interest and their Related Persons harmless from and against any Claim arising out of or related to any failure to obtain such Consent.

4.12Casualty Loss. If a Casualty Loss exists at Closing, (a) Buyer shall purchase the Subject Interest affected by the Casualty Loss notwithstanding the Casualty Loss and without any adjustment to the Purchase Price therefor and (b) Seller shall at the Closing pay to Buyer any sums paid to Seller by reason of the Casualty Loss and shall assign, transfer and set over unto Buyer all of the right, title and interest of Seller in and to any unpaid insurance proceeds, awards and other payments for such Casualty Loss.

4.13Transfer of Operatorship. Seller makes no representations or warranties to Buyer as to the transferability (or assignability) of the operatorship of any Asset. Buyer acknowledges that the rights and obligations associated with such operatorship are governed by the applicable Laws, regulatory authorities and agreement(s) and that such operatorship following the Closing will be determined in accordance therewith.

Article 5.Environmental Matters.

5.1Environmental Review. Subject to the following provisions and during the Review Period, Buyer may access and inspect the Real Property Interests (if operated by Seller) and to environmental data in Seller’s files pertaining to the Real Property Interests. Buyer may request Seller’s assistance in gaining access to Real Property Interests operated by Seller or other operators of Real Property Interests, but Buyer will be responsible for contacting the operators of such Real Property Interests to arrange for review and inspection of the Real Property Interests and of the data, information, documentation, books, and records pertaining thereto (collectively, “environmental data” for the purposes of this Section 5.1), at Buyer’s sole cost, risk and expense. Buyer specifically acknowledges that (a) any access to Seller-operated Real Property Interests or Seller’s data is given as an accommodation only, at Buyer’s sole cost, risk and expense; (b) Seller makes no representations whatsoever as to the accuracy, completeness, or reliability of any such environmental data or information derived from Buyer’s review and inspection, or otherwise disclosed to or obtained by Buyer; and (c) Buyer relies and depends on and uses any and all such environmental and information derived from Buyer’s review or inspection exclusively and entirely at its own risk and without any recourse to Seller whatsoever. Seller shall cooperate with Buyer to facilitate the performance by Buyer of any environmental testing that Buyer wishes to conduct at Buyer’s sole cost and risk prior to Closing, which testing shall be conducted in a reasonable manner so as not to interfere with Seller’s or operator’s operation of the Real Property Interests, and Seller and Buyer shall cooperate to ensure that such testing is performed on an expedited and confidential basis before Closing. Results of any such tests shall be treated as confidential, except to the extent disclosure is required under applicable law.

20

(a) To the fullest extent permitted by law, Buyer shall indemnify, defend and hold harmless Seller and it Related Persons from any and all Claims caused by, occurring from or in association with, arising out of or resulting from the activities of Buyer or any of its Related Persons in connection with said site visit and physical investigation of the Real Property Interests (including without limit Claims for injury to or death of any individual or for damage to or contamination of any property, natural resources or the environment),even if such indemnified act, omission, event or occurrence is caused in whole or in part by the negligence, fault or strict liability of any Seller, but not to the extent that any such indemnified event or occurrence is caused by or the result of the gross negligence or willful misconduct of Seller.

(b) In addition to the foregoing indemnification obligations, Buyer assumes full responsibility for all damage to the Assets and/or to operations conducted by Seller or other operators associated with the Real Property Interests that is caused by, results from or arises out of the activities of Buyer or its Related Persons in connection with said site visit and physical investigation of the Real Property Interests (including without limit environmental remediation and response costs and damage to natural resources located on, in, under or above any real property that is part of or associated with the Assets),even if such damage is caused by, results from or arises out of the negligence, fault or strict liability of Seller, but not to the extent such damage is caused by, results from, or arises out of the gross negligence or willful misconduct of Seller. Upon Seller’s request, Buyer shall immediately reimburse Seller for all such damages.

(c) Buyer shall provide Seller with written notice before its desired date for testing the Real Property Interests and written notice before its desired time for assessing the Real Property Interests and will specify in the notice the desired locations to be tested or assessed. Seller will have the right for itself or its designee(s) to be present during any testing or other assessments and retains the right to prohibit Buyer from conducting any such testing or assessment.

(d) If Buyer undertakes an environmental assessment, both the consultant (if any consultant is employed) and the scope of the proposed assessment, including testing protocols, must be approved by Seller before the work may begin. If Buyer takes samples from the Assets, Seller may require the Buyer to split any sample so that Seller may retain a sufficient split of such sample for its own testing or use. Buyer shall promptly furnish to Seller a copy of any assessment resulting from such inspection, including without limit any reports, results, data, analyses, results and conclusions thereof (collectively with any assessment, “Assessment Information”).

(e) Buyer shall provide Seller with a photocopy of any preliminary report and access to all drafts of all reports and other Assessment Information produced or obtained by Buyer as a result of any environmental assessment or testing before a final version of any report is issued. Before the final version of

21

any report is issued, Seller shall also have a reasonable opportunity to provide Buyer with comments and additional information, which Buyer agrees to review and consider before the final version of any report is issued. Upon completion of any final report, Buyer shall provide Seller with copies of such report and any other written Assessment Information and shall also provide Seller access to all Assessment Information produced or obtained by Buyer as a result of any environmental assessment or testing.

(f) Buyer shall not disclose (or permit any Related Person to disclose) any Assessment Information, or any information reviewed during such assessment, to any third Person without the prior written consent of Seller unless such disclosure is required by a lawful subpoena or order of a governmental authority. In the event disclosure is sought pursuant to a subpoena or order of a governmental authority, then Buyer shall (a) notify Seller in writing or by telephone as soon as practically reasonable prior to such disclosure; (b) take all such reasonable action, legal or otherwise, to the extent necessary to prevent or remedy any disclosure through Buyer or its Related Persons; (c) undertake commercially reasonable efforts to restrict any further disclosure in the form of a protective order, confidentiality agreement or other similar device; and (d) use commercially reasonable effects to assist Seller in any efforts to have, and shall not oppose any efforts by Seller to have, any such subpoena quashed or any such order vacated or modified.

(g) If Buyer does not acquire the Assets for any reason, then upon request by Seller it shall deliver all Assessment Information to Seller and shall destroy all materials prepared or obtained by Buyer or any Related Person that constitute or contain any Assessment Information pertaining to the Assets.

5.2Environmental Defects.

(a) By written notice delivered to Seller during the Review Period, Buyer shall notify Seller if Buyer believes that the environment associated with a Scheduled Interests (limited to those Scheduled Interests which have an Allocated Amount in excess of $0.00) contains an “Environmental Defect”, which is defined as a violation or alleged violation of Environmental Laws or if Buyer believes there is an actual or threatened exposure of any person or natural resource to Wastes to the extent, as to each individual Environmental Defect, that: (a) prosecution, if instituted, would be reasonably likely to result in a penalty, fine or damage payment of $100,000 or more, or (b) performance of corrective work in respect of such Environmental Defect required by Environmental Laws would be reasonably likely to result in expenditures of $100,000 or more, each net to Seller’s interest in the affected Scheduled Interests. Such notification (the “Environmental Defect Notice”) shall include: (i) a detailed description of such Environmental Defect, (ii) a copy of any environmental assessments, reports, data and information pertaining to such Defect, and (iii) Buyer’s calculation of the amount by which such Defects have diminished the value of the Scheduled Interests, which amount shall be determined by Buyer in good faith and in a

22

commercially reasonable manner. The value of all Environmental Defects must exceed one percent (1%) of the Purchase Price (“Environmental Defect Minimum Threshold”) before there shall be any Purchase Price adjustment or further action required of Seller under this Section with respect to an Environmental Defect.

(b) As to any Environmental Defect for which there is no reduction of the Purchase Price by virtue of the preceding provision, (x) Seller shall have no further obligation with respect to such Defect, (y) Buyer shall be deemed to have waived such Defect and (z) the Subject Interest shall be conveyed to Buyer subject to such Defect.

(c) If and when Buyer believes that an Environmental Defect may exist, Buyer shall use reasonable efforts to notify Seller of such possible Environmental Defect and furnish available information concerning such possible Environmental Defect and, from time to time thereafter as Buyer obtains more information shall provide Seller, as soon as practicable, with such additional information.

5.3Remedies for Environmental Defect.With respect to each Environmental Defect asserted by Buyer in the Environmental Defect Notice, if Seller requests, Seller and Buyer shall discuss and agree whether a particular matter constitutes an Environmental Defect. As to each claim of an Environmental Defect made by Buyer during the Review Period (and upon satisfaction of the Environmental Defect Minimum Threshold set forth in Section 5.2 above), Buyer and Seller shall endeavor to agree upon one of the following three options, with option 5.3(c) being the default selection (subject to Buyer’s right to elect to proceed under Section 5.3(b)) in the event the parties are unable to agree:

(a) Prior to or at Closing, Seller and Buyer may mutually agree in writing separate and apart from this Agreement that Seller shall correct or make arrangements for the correction of such Environmental Defect, and Closing shall proceed with Seller making such correction and subject to the provisions of Sections 9.3 and 9.4 (including but not limited to the provisions limiting this indemnification to any Claims for which Seller has received a proper Claim Notice in accordance with Section 9.4 within one year after the Effective Time), defending, indemnifying and holding Buyer and its Related Persons harmless against all Claims made by a Third Person attributable to such Environmental Defect and without reduction of the Purchase Price; or

(b) Buyer shall correct or make arrangements for the correction of such Environmental Defect after Closing, and the parties shall proceed to Closing with a reduction of the Purchase Price in an amount mutually agreed to by the parties and with Buyer defending, indemnifying and holding Seller and its Related Persons harmless against all Claims attributable to such Environmental Defect; or

(c) Buyer shall accept the Assets subject to any such Environmental Defect, the parties shall proceed to Closing without adjustment of the Purchase Price, and Seller shall, subject to the provisions of Sections 9.3 and 9.4 (including

23

but not limited to the provisions limiting this indemnification to any Claims for which Seller has received a proper Claim Notice in accordance with Section 9.4 within one year after the Effective Time), defend, indemnify and hold Buyer and Related Persons harmless against all Claims asserted by a Third Person with respect to such Environmental Defects, up to, but in no event to exceed, the lesser of (i) two percent (2%) of the Adjusted Purchase Price or the (ii) the sum of the allocated amount of each of the Schedule Interests subject to or covered by an Environmental Defect subject to this Section 5.3(c) (such amount being cumulative for any and all claims of Environmental Defect made by Buyer). In the event of a claim asserted by a Third Person of an Environmental Defect and a demand for indemnification by Buyer hereunder, Seller reserves the right to jointly negotiate with Buyer and the agency or party, if any, making such claim the right of access to the affected site, the use of temporary storage and resources at such site, to the full extent held by Buyer, and the right to perform assessment, removal and remedial operations for such Environmental Defect, at its cost and risk, and any sums so expended by Seller shall be a credit against Seller’s indemnity obligation, if any, under this Section 5.3(c).

Each party shall cooperate with the other party’s reasonable corrective work, and any operations unreasonably interfering with the corrective work shall cease until correction is completed.

(d) In no event shall the value of or the indemnification given for an Environmental Defect for a Subject Interest be for more than the Allocated Amount of such Subject Interest.

5.4Post-Closing Environmental Indemnification by Buyer. As of the Closing, but subject to the provisions of Sections 5.3(a) and (c), Buyer specifically assumes and shall be responsible for all environmentally-related duties and obligations of Seller and its Related Persons with respect to the Assets and shall protect, defend, indemnify and hold Seller and the Seller and its Related Persons harmless from and against any and all Claims under any Environmental Law (hereafter defined) with respect to the Assets including without limitation, any environmentally-related duties, conditions and obligations existing prior to or as of the Effective Time or relating to periods arising before the Effective Time. The term “Environmental Law(s)” as used here and elsewhere in this Agreement includes the Resource Conservation and Recovery Act, 42 U.S.C.A. §6901, et seq.; the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C.A. §9601, et seq.; the Clean Water Act, 33 U.S.C.A. §1251 et seq.; the Clean Air Act, 42 U.S.C.A. §7401, et seq.; the Safe Drinking Water Act, 42 U.S.C.A. §3001, et seq.; the Toxic Substances Control Act, 15 U.S.C.A. §2601 et seq.; the Oil Pollution Act of 1990, 33 U.S.C.A. §2701 et seq.; and all rules, regulations and orders adopted under the foregoing statutes, applicable state statutes addressing similar matters, or state or federal statutes enacted after the date of this Agreement applicable to any waste material, produced water, tank bottoms, sludge, or constituents thereof, radioactive materials (excluding NORM, as defined in Section 6.5), or hazardous substances (individually or collectively, “Wastes”) on or included with the Assets or the presence, disposal, release or threatened release of all Wastes on, included with, or emanating from or through the Assets into the atmosphere or in or upon land or any water

24

course or body of water, whether above or below the ground, and all other federal, state and local environmental and oil and gas laws and regulations, as well as all acts, laws, and regulations amendatory or supplemental thereto.

5.5Condition of the Assets and Specific Buyer Indemnification with Respect to NORM and Other Hazardous Substances. Except and to the extent as otherwise provided in this Agreement, Buyer specifically assumes the risk of the condition of the Assets and shall inspect the Assets prior to Closing, or hereby expressly waives such inspection right, if not timely exercised. Any such inspection, if made, shall cover, but not be limited to, the physical and environmental condition, both surface and subsurface, of the Assets. It is expressly recognized by Buyer that the lands and/or water bottoms, along with surface facilities and production equipment located thereon, having been used in connection with oil, gas, and water production, treatment, storage, and disposal activities, may contain naturally occurring radioactive materials (“NORM”), asbestos and other hazardous substances as a result of these operations. The generation, formation, or presence of NORM, asbestos or other hazardous substances in or on the Assets shall be the sole responsibility of Buyer, and Buyer and all future assignees and successors of Buyer shall defend, indemnify and hold Seller and its Related Persons harmless from any and all Claims resulting from any and all claims, demands, losses, liabilities, liens, judgments, settlements, suits, causes of action, fines, penalties, fees, costs, and expenses (including, without limitation, attorneys fees, court costs, and expenses associated with investigation of claims, testing and assessment), whether based on any theory of negligence, tort, breach of contract, breach of warranty, strict liability, regulatory liability or statutory liability, regardless of the sole, joint or concurrent negligence, breach of contract, breach of warranty, strict liability, regulatory liability, statutory liability, or other fault or responsibility of Seller or any other person or party in any way arising from, resulting from or related to the presence of NORM, asbestos or other hazardous substances, whether such NORM, asbestos or other hazardous substance was in place before or after the Effective Time. Any conveyance, transfer or assignment of all or part of the Assets by Buyer, its successors or assigns, in which the grantee, transferee or assignee fails to expressly assume this obligation shall be deemed null and void. Accordingly, lands and/or water bottoms, the Wells, and the Equipment transferred herein are transferred with the restriction that they will be used only in connection with oil and gas producing activities associated with the Real Property Interests, and will not be subsequently transferred by Buyer or Buyer’s assignee for unrestricted use unless the concentrations of NORM, asbestos or other hazardous substances associated therewith are independently determined by a competent laboratory and are found below the levels specified as allowable for unrestricted transfer as set forth in any and all applicable laws, orders, rules or regulations of any governmental agency or court having jurisdiction. Additionally, Buyer agrees to comply with all provisions of such laws, orders, rules or regulations applicable to Real Property Interests, such lands and/or water bottoms, the Wells, and the Equipment. Buyer further agrees to cause the provisions of this clause to be included in all subsequent sales or transfers of any interest in the Assets, and to cause all purchasers or transferees of the Assets to expressly acknowledge and assume all such obligations.

5.6Waiver. In the event any Asset, or any portion thereof, is not attributable to any Subject Interest listed on Exhibit “G-4” hereto with an Allocated Amount greater than $0.00, then such interest shall not be subject to the provisions of Section 5.3. Unless raised by

25

proper notice within the applicable time period set forth in Section 5.2, Buyer waives for all purposes all objections associated with the environmental, physical, and other condition of the Assets (including Environmental Defects), and Buyer (on behalf of itself and the Buyer and its Related Persons and their successors and assigns) irrevocably waives any and all Claims, (except subject to the limitations set forth in Section 9.3 and 9.4, Claims covered under Seller’s indemnities pursuant to Section 5.3 (a) and (c)), that they may now or hereafter have asserted against Seller associated with the same.

Notwithstanding anything to the contrary contained elsewhere in this Agreement, Seller’s cumulative indemnity obligations to Buyer and the its Related Persons under this Agreement shall not exceed the Adjusted Purchase Price.Furthermore, in no event shall Seller’s cumulative indemnity obligations to Buyer and its Related Persons with regard to an Asset exceed that Asset’s Allocated Amount.

9.4Procedure for Claims. The following provisions shall apply for a party (a “Claimant”) to assert a Claim under or arising out of this Agreement or any Assignment (whether for protection, indemnity, defense, warranty, breach of this Agreement or otherwise) against the other party (the “Respondent”). The following provisions shall also apply for a Related Person of a party (also, a “Claimant”) to assert a Claim under or arising out of this Agreement or any Assignment for protection, indemnity or defense.

(a) To assert a Claim, the Claimant shall give to the Respondent a written notice (a “Claim Notice”) that includes (1) the specific details of the Claim and (2) specific basis under this Agreement for the Claim. In the event that the Claim is by a Third Person against the Claimant (a “Third Person Claim”), the Claimant shall submit its Claim Notice promptly after the Claimant has actual

36

knowledge of the Third Person Claim and shall enclose a copy of all papers (if any) served or otherwise received with respect to the Third Person Claim. Nonetheless, the failure of Seller or a Related Person of Seller to give notice of a Third Person Claim as required by this Section 9.4(a) shall not relieve Buyer of its defense and indemnity obligations under this Article 9 except to the extent such failure materially prejudices Buyer’s ability to defend effectively against the Third Person Claim.

(b) In the case of a Claim based upon a Third Person Claim, the Respondent shall notify the Claimant within ten (10) Business Days from Respondent’s receipt of the Claim Notice whether the Respondent admits or denies its obligation to indemnify and defend the Claimant against the Third Person Claim. If the Respondent does not notify the Claimant within such ten (10) Business Day period whether the Respondent admits or denies its obligation, the Claims for which the Claimant is seeking indemnity and defense shall be conclusively deemed an obligation of the Respondent hereunder. The Claimant is authorized, prior to and during such ten (10) Business Day period, to file any paper (and take any action) that it shall deem necessary or appropriate to protect its interests.

(c) If the Respondent admits, or is deemed to have admitted, its obligation to indemnify and defend the Claimant against the Third Person Claim, it shall defend diligently, at its sole cost and expense, the Third Person Claim and shall have full control of such defense and proceedings, including without limitation any compromise or settlement thereof, subject to the limitations herein. If requested by the Respondent, the Claimant shall cooperate with any actions reasonably necessary to contest any Third Person Claim that the Respondent elects to contest (provided, however, that no Claimant shall be required to bring any counterclaim or cross-complaint against any Person). A Claimant may at its sole cost and expense participate in, but not control, any defense or settlement of any Third Person Claim controlled by the Respondent. Without the written consent of the Claimant, which consent shall not be unreasonably withheld, the Respondent shall not settle any Third Person Claim against a Claimant or consent to the entry of any judgment with respect thereto that (1) does not result in a final resolution of the Claimant’s liability with respect to the Third Person Claim (including, in the case of a settlement, an unconditional written release of the Claimant), (2) imposes on the Claimant any material non-financial obligation, or any financial obligation outside the scope of the Respondent’s indemnity obligations under this Agreement or (3) imposes on the Claimant a financial obligation that the Respondent is unable or unwilling to immediately satisfy.

(d) If the Respondent does not admit its obligation or admits its obligation but fails to diligently defend or settle the Third Person Claim, then the Claimant shall have the right to defend against the Third Person Claim at the sole cost and expense of the Respondent, with counsel of the Claimant’s choosing, reserving to the Claimant all rights granted hereunder or otherwise against the Respondent, but subject to the right of the Respondent to admit its obligation and

37

assume the defense of the Third Person Claim at any time prior to settlement or final determination thereof. If the Respondent has not yet admitted its obligation for indemnity and defense with respect to a Third Person Claim, the Claimant shall send written notice to the Respondent of any proposed settlement and the Respondent shall have the option for five (5) Business Days following receipt of such notice to (1) admit in writing its obligation for indemnity and defense with respect to such Third Person Claim and (2) if its obligation is so admitted, assume the defense of the Third Person Claim, including without limitation the power to reject the proposed settlement. If the Claimant settles any Third Person Claim over the objection of the Respondent after the Respondent has timely admitted its obligation in writing and assumed the defense of the Third Person Claim, the Claimant shall be deemed to have waived any right to indemnity therefor.

9.5Waiver and Limitation of Indemnities and Certain Damages.

(a) In no event shall Respondent have any obligations to indemnify or defend a Claimant if the Claim for which indemnity or defense is sought was caused by the gross negligence or willful misconduct of the Claimant. Nor shall any indemnity provisions in this Agreement apply to matters affecting properties (real, personal or mixed) and appurtenant rights (contractual or otherwise) other than those that are covered by this Agreement.

(b) Each party (for itself and its Related Persons), along with any Person asserting a Claim under this Agreement, waives and agrees not to seek indirect, consequential, punitive, incidental, special, multiple, statutory or exemplary damages of any kind with respect to any Claim based on, related to or arising out of (in whole or in part in any way) this Agreement, any transaction contemplated hereby or any breach hereof or thereof (whether arising before, at or after any Closing). However, this provision does not diminish or otherwise affect the Parties’ rights and obligations to be indemnified against, and provide indemnity for, indirect, consequential, incidental, special, punitive or exemplary damages awarded to any third party for which indemnification is provided in this Agreement or Seller’s right to receive liquidated damages, including the Deposit, pursuant to the provisions of Section 8.2(d).

9.6Records. At Closing Seller shall furnish to Buyer all Records. Nonetheless, Seller shall have the right, at its expense before delivery of such Records to Buyer, to make and retain copies of such Records. Buyer shall maintain the Records received from Seller for a period of at least seven (7) years after the Closing and at reasonable times shall afford Seller full access to the Records as reasonably requested by Seller for review and for making

38

and retaining copies thereof at Seller’s expense. If any portion of the Records is desired to be destroyed, Buyer shall use reasonable efforts to provide Seller with written notice and the reasonable opportunity to take possession of any or all of the same before such destruction.

9.7Confidentiality. The Confidentiality Agreement shall terminate effective as of the Closing only as to the Assets conveyed to Buyer.

9.8Transfer of Operatorship. Except as prohibited by Law or applicable agreements, Buyer shall, upon and after Closing, assume operatorship of (a) all Assets (or portions thereof) operated by Seller (or its designee) at the Effective Time.

As promptly as practicable, Buyer shall file with all pertinent Governmental Authorities all pertinent change-of-operatorship forms and similar applications and instruments.

9.9Conveyance Costs. Buyer shall pay all transfer, sales and use Taxes, if any, from or arising out of the sale of the Subject Interests.

Without limiting the foregoing, Buyer shall file each Assignment for recordation in the conveyance records of each Louisiana parish in which any Leases or Units subject to such Assignment are located and shall make all necessary filings with any Governmental Authority. Buyer shall file and record all such documents as promptly as practicable after the Closing and, as promptly as practicable after such recording or filing, shall furnish Seller with all recording data and a certified copy (or other evidence acceptable to Seller) of all such filings.

9.10Revenues, Expenses and Capital Expenditures.

(a) Except for the Imbalance and as otherwise provided for herein, Seller shall be entitled to all revenues, credits, refunds, deposits and accounts receivable attributable to, or arising out of the ownership, operation or use of, the Subject Interests before the Effective Time, no matter when received.

(b) Except as otherwise provided for herein, Buyer shall be responsible for, and shall pay or cause to be paid when due, all costs, expenses, expenditures, payments and payables (including without limitation capital expenditures, royalties, rentals, Taxes, deposits, advanced billings paid under an operating agreement and all prepaid insurance premiums, utility charges, processing, gathering or transportation charges) and Claims attributable to, or based on, related to or arising out of (in whole or in part in any way) (i) the ownership, operation or use of, any Subject Interest at or after the Effective Time

39

9.11Taxes.

(a) Subject to Sections 9.1, 9.3 and 9.11(d), Seller shall be responsible for, and shall pay or cause to be paid when due, all Taxes related to or arising out of the ownership, operation or use of the Subject Interests before the Effective Time.

(b) Subject to Section 9.11(d), Buyer shall be responsible for, and shall pay or cause to be paid when due, all Taxes related to or arising out of the ownership, operation or use of the Subject Interests at or after the Effective Time (excluding Seller’s income Taxes from its sale of the Subject Interests hereunder).

(c) Buyer shall be solely responsible for, and shall pay or cause to be paid when due, all transfer, sales, use or similar Taxes resulting from or associated with the transactions contemplated under this Agreement and all documentary, filing and recording fees required in connection with the filing, recording and approval of the Assignments.

(d) Ad valorem and other property Taxes due in respect of the Subject Interests for the tax period covering the Effective Time shall be prorated between Buyer and Seller as of the Effective Time. To the extent that Seller has paid any such Taxes before Closing, Buyer will reimburse Seller for the portion of such Taxes that is attributable to the period after the Effective Time. Buyer shall pay or cause to be paid prior to delinquency, and shall be responsible for, all such Taxes not paid before Closing, and Seller will reimburse Buyer for the portion of such Taxes that is attributable to the period before the Effective Time.

(e) The party responsible for a particular Tax shall be entitled to all deductions, credits and refunds pertaining to such Tax, no matter when received.

9.12Further Assurances. From and after Closing, at the request of Seller but without further consideration, Buyer shall execute and deliver or use reasonable efforts to cause to be executed and delivered such other instruments of conveyance and take such other actions as Seller reasonably may request to more effectively put Seller in possession of any property that was not intended by the parties to be conveyed, or should not have been conveyed, to Buyer (including without limitation reassignment from Buyer to Seller of any Subject Interests that were conveyed in violation of a valid Preferential Right or consent to assignment). From and after Closing, at the request of Buyer but without further consideration, Seller shall execute and deliver or use reasonable efforts to cause to be executed and delivered such other instruments of conveyance and take such other actions as Buyer reasonably may request to more effectively put Buyer in possession of the Subject Interests intended to be conveyed. If any of the Subject Interests are incorrectly described, the description shall be corrected upon proof of the proper description. From and after the Closing, Buyer and Seller shall each execute, acknowledge and deliver to the other such

40

further instruments and take such further action as may be reasonably requested in order to more effectively assure to the other the full beneficial use and enjoyment of the Subject Interests and otherwise to accomplish the purposes of the transaction contemplated by this Agreement.

9.13Transfers. The parties acknowledge and agree that Buyer’s obligations under this Agreement and under each Assignment are real obligations and run with the land and with each subsequent Transfer of the Subject Interests. Any Transfer by Buyer (or any permitted successor or assign thereof) of any right, title or interest in or to any or all portions of the Subject Interests or any Assignment shall be void and unenforceable unless such Transfer specifically references, and is made subject to, this Agreement and such Assignment and specifically provides that each Person acquiring under such Transfer expressly assumes (to the extent of the interest acquired) Buyer’s obligations under this Agreement and such Assignment. The parties understand and agree that neither any such Transfer nor any delegation of any or all portions of Buyer’s obligations hereunder shall relieve or release Buyer (or any successor or assign) of any obligations to Seller under this Agreement unless Buyer (or any successor or assign) is expressly relieved or released thereof in writing by Seller in its sole absolute discretion.

Any such recovery by Seller under the Guaranty shall satisfy only those liabilities and obligations of Buyer with respect to the particular Default and only to the extent that Seller has been reimbursed therefor by recovery under the Guaranty.

9.16.4 Other Remedies Reserved.Seller’s right to proceed in the manner above described to correct or redress Defaults of Buyer or its successors or assigns is not intended to be nor shall it limit or be exclusive of any other right or remedy, whether personal or in “rem”, available to Seller under this Agreement, the Assignments, and/or any amendments thereto, or otherwise by law, all of which remedies are expressly and fully ratified, granted to and reserved to Seller.

10.19.1Sole and Exclusive Method for Resolution of Disputes. Unless otherwise expressly provided herein, any dispute arising out of, in connection with or relating to this Agreement shall be resolved in accordance with the procedures specified in this Article 10.19, which shall be the sole and exclusive procedures for the resolution of any such disputes. To the extent, however, that the dispute involves a claim for indemnity otherwise covered by Article 9 of this Agreement, the provisions of this Article 10.19 shall apply in addition to, not in lieu of, the provisions of Article 9.

10.19.2Negotiations Between Executives.The parties shall attempt to resolve any dispute arising out of or relating to this Agreement promptly by negotiation between executives who have authority to settle the controversy and who are at a higher level of management than the persons with direct responsibility for administration of this Agreement. Either party may give the other party written notice of any dispute not resolved in the normal course of business. Within 15 days after delivery of the notice, the receiving party shall submit a written response to the other party. The notice and response shall include: (a) a statement of that party’s position and a summary of arguments supporting that position, and (b) the name and title of the executive who will represent that party and of any other person who will accompany the executive. Within 30 days after delivery of the initial notice, the executive of both parties shall meet at a mutually acceptable time and place, and thereafter continue to meet as often as they reasonably deem necessary, to attempt to resolve the dispute. All negotiations pursuant to this clause are confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence.

10.19.3Arbitration. If the dispute has not been resolved by negotiation as provided herein within 60 days after delivery of the initial notice of negotiation described in 10.19.2, or if the parties failed to meet within 30 days after delivery of such notice, then either party may initiate arbitration as the exclusive means to

47

finally resolve such dispute.
