Nonetheless, even if any single item of income or expense can be categorized under more than one of the following categories, such item shall be counted only once for purposes of making adjustments to the Purchase Price. The Purchase Price shall be adjusted in accordance with this Section 1.3, but, notwithstanding any other provision of this Agreement, shall not be adjusted for: (i) actual or projected changes in production rates, (ii) alternate interpretations of reserves and (iii) the condition of the Equipment. (a) The Purchase Price shall be adjusted upward by the following amounts: 1) the amount of all expenditures actually paid by Seller in connection with the operation of the Assets which are, in accordance with GAAP, attributable to the period of time after the Effective Time, including without limitation royalties, rentals and other charges; ad valorem, property, production, excise, severance, and any other Taxes (other than income Taxes) based upon or measured by the ownership of property or the production of Hydrocarbons or the receipt of proceeds therefrom, in each case attributable to the Assets and not deducted or netted from proceeds under Section 1.3(b), as well as expenses properly incurred under applicable operating agreements, including any charges incurred by Seller as a non-operator, including without limitation geological and land costs and costs of drilling, testing, treating, completing, reworking, deepening, side-tracking, and plugging and abandoning wells; 2) the amount of (i) gross proceeds actually received by Buyer, or offset by third parties against amounts owed by Buyer, from the sale of Hydrocarbons that are produced from or attributable to the Assets prior to the Effective Time, net of royalties that are owed to a Third Person, severance taxes, and marketing costs (including without limitation transportation, compression, gathering and processing fees) not reimbursed to Buyer or Seller by the purchaser of such Hydrocarbons, and (ii) any other income and proceeds actually received by Buyer, or offset by third parties against amounts owed by Buyer, with respect to the Assets, which are, in accordance with GAAP, attributable to the period of time prior to the Effective Time; 3) the value of all Hydrocarbons in storage as of the Effective Time that is credited to the Assets, such value to be the actual price received for such Hydrocarbons upon the first sale thereof, or absent a sale, then such value shall be based upon the average market price posted in the area for Hydrocarbons of similar quality and grade in effect as of the Effective Time, in each case net of royalties that are owed to a Third Person, severance taxes, and marketing costs (including without limitation transportation, compression, gathering and processing fees) not reimbursed by the purchaser of such Hydrocarbons; 4) all Taxes for which Buyer is responsible under Section 9.11, to the extent they are paid by or on behalf of Seller; 5) the amount for any underproduced gas position of Seller as described in Section 1.4(b); 6) the amount of the Negative Balance Suspense Accounts as of the Effective Time; 7) all additional amounts mutually agreed upon in writing by Buyer and Seller; and -2- 8) an amount equal to the sum of any Upward Adjustment provided for in Section 4.9.

To the best of Seller's Knowledge, the volume of any gas imbalance of Seller with respect to the Subject Interests, Leases, Wells and Units as of the Effective Time and whether at the wellhead, platform or otherwise are set forth on Exhibit "M" hereto (collectively the "Imbalance"). (a) If pursuant to the Imbalance any gas volumes are due and owing by Seller to one or more underproduced Persons as of the Effective Time, Seller shall pay to Buyer (or credit Buyer for) an amount equal to the product of the Imbalance Price times such volume (in MMBtu's), net of any royalties, overriding royalties or other burdens, in order to reflect the estimated value and liability of such overproduction as of the Effective Time. (b) If pursuant to the Imbalance any gas volumes are due and owing to Seller by one or more overproduced Persons as of the Effective Time, Buyer shall pay to Seller an amount equal to the product of the Imbalance Price times such volume (in MMBtu's), net of any royalties, overriding royalties or other burdens, in order to reflect the estimated value and liability of such underproduction as of the Effective Time. The parties acknowledge and agree that (a) the Imbalance reflects the estimated amount of any gas imbalance owed to or by Seller and (b) the Imbalance Price reflects their estimated value of any underproduced or overproduced gas -3- position of Seller in connection with any Subject Interest as of the Effective Time, net of royalties, Taxes, overriding royalties and other burdens. 1.5 Preliminary Accounting Statement. At least three (3) Business Days before the anticipated Closing, Seller shall prepare and present to Buyer a "Preliminary Accounting Statement" reflecting all then-applicable upward and downward adjustments to the Purchase Price as provided in Section 1.3, determined in accordance with GAAP as used in the oil and gas industry and using the best information then available. 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. 1.6 Final Accounting Settlement. (a) Within ninety (90) Days after Closing but not earlier than sixty (60) days after Closing, Seller shall deliver to Buyer a statement (the "Final Accounting Settlement") setting forth (1) a detailed calculation of the Adjusted Purchase Price and (2) the net amount owing by Seller to Buyer or by Buyer to Seller, as appropriate. (b) Within thirty (30) Days after Buyer receives the Final Accounting Settlement, Buyer may submit to Seller a written notice (an "Objection Notice") that (1) sets forth each item in Seller's Final Accounting Settlement that Buyer contends does not comply with this Agreement, (2) provides the basis for each such objection, (3) provides supporting documentation for each such objection and (4) sets forth, based on all such objections, both the amount that Buyer contends equals the Adjusted Purchase Price and the net amount that Buyer contends is owing by Seller to Buyer or by Buyer to Seller, as appropriate. If Buyer does not timely deliver an Objection Notice in accordance with the preceding sentence, the Final Accounting Settlement, in the form delivered by Seller, shall be deemed to be true and correct and shall be final and binding on the parties. (c) If Buyer timely delivers an Objection Notice in accordance herewith, the parties shall use reasonable efforts to meet as soon as reasonably practicable to attempt to resolve all objections set forth in the Objection Notice. (d) If the parties fail to amicably resolve each objection in a timely Objection Notice, the disputed items in the Final Accounting Settlement shall be resolved by submitting the same to the Referee in Houston, Texas. But no objection shall be submitted to the Referee until at least twenty (20) Business Days after the meeting prescribed in Section 1.6(c). Each party giving any notice or submission to the Referee shall simultaneously provide a copy thereof to the other party. The Referee shall resolve the dispute(s) within twenty (20) Business Days after having the relevant materials submitted for review. The Referee shall act as an arbitrator for the limited purpose of determining the specific disputed matters submitted by either party and may not award damages or penalties to either party with respect to any matter. The decision of the Referee shall be binding on the parties and non-appealable. In determining the proper amount of the Adjusted Purchase Price, the Referee shall not fix the Adjusted Purchase Price at an amount more than the amount proposed by Seller in its Final Accounting Settlement nor at an amount less than the amount proposed -4- by Buyer in its Objection Notice. The Referee shall not consider any objection to Seller's Final Accounting Settlement that is not set forth in a timely Objection Notice. Each party shall each bear its own legal fees and other costs of presenting its case. The fees and expenses of the Referee shall be borne fifty percent (50%) by Buyer and fifty percent (50%) by Seller; each party shall pay its proportionate share of the Referee's fees and expenses within ten (10) Business Days of the later of (a) the date when the Referee's decision is issued or (b) the receipt by such party of an itemized statement of such fees and expenses. (e) Within five (5) Business Days after the final determination of the Adjusted Purchase Price (whether by agreement or deemed agreement between the parties or by decision of the Referee), each party shall pay all net amounts reflected in the Final Accounting Settlement as being due and payable to the other party. Such net amounts shall bear legal interest from and after, but not before, such due date. 1.7 Allocation. The Allocated Amounts (which shall be mutually agreed upon by the parties) are to be used solely (a) to adjust the Purchase Price in accordance with Title Defects, Environmental Defects and Preferential Rights. To the extent that the transactions contemplated by this Agreement are subject to the reporting requirements of Section 1060 of the Internal Revenue Code of 1986, as amended, the parties will confer and cooperate in the preparation and filing of their respective federal and state tax reporting forms to reflect a consistent reporting of the agreed upon allocation.

Buyer represents and agrees that any of the Records or other information (written, oral or otherwise) previously, now or hereafter furnished or otherwise made available to Buyer or any other Person by Seller or any of its Related Persons is provided as a convenience only and shall not create or give rise to -10- any liability against Seller or any of its Related Persons; that any reliance on or use of same shall be at Buyer's sole peril and risk to the maximum extent permitted by Law; that Buyer is not relying on Seller's skill or judgment in selecting any Subject Interest (even if Seller may know or have reason to know of Buyer's particular purpose for buying any Subject Interest) or on any warranty or representation by any Related Person of Seller; and that, upon Closing, the Subject Interests shall be sold and conveyed from Seller to Buyer "as is", "where is" and with all faults in their condition and state of repair as of Closing, without recourse. Except as expressly provided in this Agreement: (a) Buyer represents that it is relying solely on its own examination and inspection of the Subject Interests and Assets for title, environmental and all other purposes and is buying the Subject Interests at its sole peril and risk; (b) Seller negates and disclaims any and all (and Buyer represents that it is not relying on, and that, except as expressly stated in Article 2 above and as to the Special Limited Title Warranty, Seller has not made, any) representations and warranties (express, statutory, implied or otherwise), including without limitation concerning this Agreement, any Assignment or any Subject Interest, Asset or Assumed Obligation; and (c) Seller negates and disclaims any and all liability and responsibility for or associated with and any and all representations and warranties concerning (and Buyer acknowledges that it is not relying on and that Seller has not made any representations or warranties concerning) the quality, accuracy, completeness or materiality of any Records or other information previously, now or hereafter furnished or otherwise made available (electronically, orally, by video, in writing or by or through any other medium or means) to Buyer or any other Person; and (d) Except and only to the extent so provided in Article 9 for those matters for which Seller agrees to indemnify Buyer and Buyer's Related Persons pursuant to Section 9.2 below, Buyer irrevocably waives, and releases Seller, each prior owner of any Subject Interest and their Related Persons from and against, all Claims (whether currently asserted or unasserted, accrued or unaccrued, known or unknown or foreseen or unforeseen and whether direct, indirect, contingent or otherwise) based on, related to or arising out of (in whole or in part in any way) this Agreement, any Assignment or any Subject Interest, Asset or Assumed Obligation, whether or not arising at any time before, at or after the Effective Time and whether or not caused or contributed in whole or in part by the negligence, fault or strict liability (whether active, passive, sole, simple, concurrent, contingent or otherwise) of, or breach of contract or violation or Law by, Seller or any other Person and whether based on, related to or arising out of (in whole or in part in any way) any theory of liability or fault whether in tort, contract, quasi-contract, strict liability, unseaworthiness of any vessel, misrepresentation, equity, indemnity, contribution, violation or operation of any Law or any other cause whatsoever. Without limiting the generality of the foregoing, these negations and disclaimers by Seller and these waivers, releases of Claims and representations by Buyer relate without limitation to: 1) other than the Special and Limited Title Warranty, title, ownership, consideration, status, peaceable possession, eviction (under Louisiana Civil Code article 2500 or otherwise) or non-declared -11- encumbrances (under Louisiana Civil Code article 2500 or otherwise); 2) the geographic, geologic or geophysical characteristics associated with any or all of the Real Property Interests and Wells, including without limitation the existence, quality, quantity or recoverability of prospects or Hydrocarbon reserves; 3) the costs, expenses, liabilities, status, revenues, receipts or economic value associated with, the continued productivity or financial viability of, the contractual, economic or financial data associated with or the rights or obligations (including without limitation the federal, state or local income or other Tax consequences) associated with this Agreement, any Assignment, any or all portions of the Subject Interests, Assets or agreements to which any Subject Interest is subject; 4) the operatorship of any or all portions of the Assets or any other Wells, Units or property; 5) fitness for Buyer's intended use or purpose, for any other particular use or purpose or for ordinary use (under Louisiana Civil Code article 2475 or 2524 or otherwise) or merchantability; 6) freedom from, diminution in value because of or the presence or absence of redhibitory or other defects or vices (under Louisiana Civil Code article 2520 et seq. or otherwise), whether known or unknown and whether apparent, patent, latent, hidden or otherwise; 7) the environmental or physical condition or state of repair (whether or not arising out of any environmental damage or defect or any violation of any Environmental Law or other Law) of any or all of the Assets or the protection of the environment or of human health or safety; 8) the past or current presence or absence of NORM, asbestos, pollution, naturally occurring waste, hazardous or toxic materials or the costs, requirement or need (under any Environmental Laws or otherwise) for Plugging and Abandonment or any investigation, study, assessment, repair, clean-up, decommissioning, detoxification, remediation, removal, transportation or disposal (including without limitation for any such materials, any waste disposal or Hydrocarbon facility or any or all portions of the Assets); 9) conformity with models or samples of materials; 10) the cost, expense or ability to copy, transmit or use any electronic data; 11) return or reduction of the Purchase Price or the Adjusted Purchase Price; 12) rescission by Buyer of this Agreement or any Assignment; or 13) any Environmental or Non-Environmental Claim previously, now or hereafter asserted. -12- NOTWITHSTANDING THE FOREGOING IN THIS SECTION 4.4, BUYER IS EXPRESSLY ENTITLED TO RELY ON THE REPRESENTATIONS AND WARRANTIES BY SELLER EXPRESSLY SET FORTH IN ARTICLE 2 AND THE SPECIAL AND LIMITED TITLE WARRANTY AND SHALL BE ENTITLED TO ALL AVAILABLE RECOURSE SHOULD ANY OF SUCH REPRESENTATIONS OR WARRANTIES BE INACCURATE, SUBJECT, HOWEVER, TO APPLICABLE LIMITATIONS SET FORTH IN ARTICLE 9 BELOW. FURTHERMORE, IN THE EVENT OF ANY CONFLICT BETWEEN ANY PROVISION OF THIS SECTION 4.4 AND ANY OTHER PROVISION OF THIS AGREEMENT OR ANY PROVISION OF ANY ASSIGNMENT, SUCH OTHER PROVISION OF THIS AGREEMENT OR PROVISION OF AN ASSIGNMENT SHALL CONTROL. 4.5 Disclaimer 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 waterbodies. 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 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). 4.6 Title Defects. By written notice delivered to Seller during the period commencing on the date of this Agreement and ending at 11:59 p.m. Central Time on January 8, 2005 (the "Objection Period") (each such timely notice, a "Title Defect Notice"), Buyer may notify Seller of the existence of any matter that it 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) supporting documentation necessary for Seller to analyze Buyer's computations and the existence and amount of such Title Defect. -13- If and when Buyer believes that a Title Defect may exist, Buyer shall use reasonable efforts to 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. 4.7 Seller's Election to Cure. As to each Scheduled Interest for which Buyer asserts an alleged Title Defect in a Title Defect Notice during the Objection 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 judgment, is sufficient to cure the Title Defect. Such material delivered by 11:59 p.m. on January 13, 2005 shall be deemed sufficient and acceptable to Buyer unless by 5:00 p.m. on January 17, 2005 Seller receives from Buyer written notice that the curative is not acceptable. (b) If Seller fails to cure a Title Defect in accordance with the provisions of Section 4.7(a), notwithstanding anything herein to the contrary, the Purchase Price shall not be reduced for a Title Defect (i) unless the Downward Defect Adjustment (as determined in accordance with the provisions of Section 4.8) for such Title Defect exceeds Fifty Thousand and No/100 Dollars ($50,000) or (ii) unless and until the aggregate of all such Downward Defect Adjustments (which satisfy subpart (a)) exceeds $200,000.00 (which amount shall be a threshold, not a deductible). As to any asserted Title Defect for which there is no reduction of the Purchase Price by virtue of the preceding sentence, for which Seller cures same, or for which there is a reduction in the Purchase Price or, (x) Seller shall have no further obligation with respect to such Title Defect, (y) Buyer shall be deemed to have waived such Title Defect and (z) the Subject Interest shall be conveyed to Buyer subject to such Title Defect. (c) At Closing, Seller may add to Exhibit "D" and Exhibit "E" 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 additional Excluded Assets under this Section. 4.8 Downward Defect Adjustment. 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 Scheduled 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 Schedule Interest stated on Exhibit "H", then the -14- Downward Defect Adjustment for such Title Defect shall be the product of the Allocated Amount of such Scheduled Interest on Exhibit "H" 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 "H". 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 for the Title Defect shall be 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 Scheduled 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. 4.9 Upward Adjustments. (a) If, during the Review Period, 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 "H", such party shall, as soon as practicable, notify the other party of such inaccuracy (an "Additional Interest"). Such notice shall include: (i) a description of the affected Scheduled Interest (or interest therein or portion thereof); and (ii) a 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. If necessary, the parties shall enter into such additional agreements and instruments as are required to affect 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). 4.10 Preferential Rights. Seller shall send to the holder of each right listed in Exhibit "O" (each a "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 Allocated Amount for such Subject Interest. Seller shall deliver to Buyer copies of all such notices and any responses thereto. -15- (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, with one hundred twenty (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 no longer constitute an "Excluded Asset" by virtue of Section 4.10(a)). 4.11 Consents to Assignment. As between Buyer and Seller, Seller shall be responsible for exercising reasonable efforts to obtain those necessary consents and approvals which must be obtained prior to Closing and for giving all necessary notices of assignment of the Subject Interests from Seller to Buyer (each a "Consent", which include but are not limited to those on Exhibit "P" hereto which are customarily obtained prior to Closing). Nonetheless, before and following Closing, Buyer and Seller shall use 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)). (c) If, before Closing, a Consent concerning an Asset in the South Bourg Field (which is defined to include all Assets pertaining to the Leases and other interests described on Exhibit "R" hereto) has not been obtained, satisfied, or waived (if the parties mutually agree to such waiver) then (i) each and every Asset pertaining to or covering the South Bourg Field 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 Interests. -16- (d) 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. 4.12 Casualty 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. 4.13 Transfer of Operatorship. Seller makes no representations or warranties to Buyer as to the transferability (or assignability) of the operatorship of any Subject Interest or 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. 5.1 Environmental Review. Subject to the following provisions and until 5:00 p.m. on January 17, 2005, Buyer may inspect the Assets operated by Seller and environmental data in Seller's files pertaining to the Assets and at Buyer's request, Seller shall contact the operators of Assets not operated by Seller to arrange for review and inspection of such Assets 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 Assets 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 manner so as not to unreasonably interfere with Seller's or operator's operation of the Assets, 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. (a) To the fullest extent permitted by applicable Law, Buyer shall indemnify, defend and hold harmless Seller and its 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 visits and physical investigations of the Assets -17- (including without limitation 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 Assets that is caused by, results from or arises from the activities of Buyer or its Related Persons in connection with said site visits and physical investigations of the Assets (including without limitation 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 at least two (2) Business Days written notice before its desired date for testing the Assets and at least one (1) Business Day written notice before its desired time for assessing the Assets 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, which is not reasonable and customary in a transaction such as the one contemplated hereby. (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, which approval shall not be unreasonably withheld and/or delayed. If Buyer takes samples from the Assets, Seller may require 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 limitation any reports, results, data, analyses, results and conclusions thereof (collectively with any assessment, "Assessment Information"). (e) Buyer shall provide Seller with a copy 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 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 a copy 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 -18- Authority. In the event disclosure is sought pursuant to a subpoena or order of a Governmental Authority, Buyer shall (a) notify Seller in writing at least five (5) days before such disclosure (b) use commercially reasonably efforts to undertake reasonable efforts to restrict any further disclosure in the form of a protective order, confidentiality agreement or other similar device; and (c) use reasonable efforts 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. If Buyer does not acquire the Assets for any reason, then upon request by Seller it shall deliver to Seller all Assessment Information and all materials prepared or obtained by Buyer or any Related Person that constitute or contain any Assessment Information pertaining to the Assets. 5.2 Environmental Defects. (a) By written notice delivered to Seller during the time period prior to 5 p.m. on January 17, 2005 ("Environmental Objection Period"), Buyer shall notify Seller if Buyer believes that the environment associated with a Scheduled Interest 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 One hundred thousand and No/100 Dollars ($100,000.00) 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 One hundred thousand and No/100 Dollars ($100,000.00) or more. Such notification (the "Environmental Defect Notice") shall include: (i) a description of such Environmental Defect, (ii) a copy of any environmental data 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 reasonable manner ("Asserted Defect Value"). 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 Section 5.3 with respect to an Environmental Defect. (b) As to any Environmental Defect for which there is no further action or adjustment, (x) Seller shall have no further obligation with respect to such Environmental Defect, (y) Buyer shall be deemed to have waived such Environmental Defect and (z) the Subject Interest shall be conveyed to Buyer subject to such Environmental 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. 5.3 Remedies for Environmental Defect. With respect to each Environmental Defect asserted by Buyer in an 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 -19- Buyer during the Environmental Objection 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 election to proceed under Section 5.3(b)) in the event the parties are unable to agree upon subparts (a) or (b) below: (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 without reduction of the Purchase Price and with Seller making such correction and, subject to the provisions of Sections 9.3 and 9.4 (including without limitation 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 (1) 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; or (b) At Buyer's option, Buyer may elect to make corrections of 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 without limitation the provisions limiting this defense and indemnification to any Claims for which Seller has received a proper Claim Notice in accordance with Section 9.4 within one year after the Closing Date), defend, indemnify and hold Buyer and its 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, five percent (5%) of the Adjusted Purchase Price (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 attributable to 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 and 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. 5.4 Post-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's Related Persons harmless from and against any and all Claims under any Environmental Law -20- (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. ss. 6901, et seq.; the Comprehensive Environmental Response, Compensation, and Liability Act, 42 U.S.C.A. ss. 9601, et seq.; the Clean Water Act, 33 U.S.C.A. ss.1251 et seq.; the Clean Air Act, 42 U.S.C.A. ss. 7401, et seq.; the Safe Drinking Water Act, 42 U.S.C.A. ss.3001, et seq.; the Toxic Substances Control Act, 15 U.S.C.A. ss. 2601 et seq.; the Oil Pollution Act of 1990, 33 U.S.C.A. ss.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 5.5), 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 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. 5.5 Condition 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.

Termination. 8.1 Right of Termination. This Agreement may be terminated at any time at or before Closing by notice given at or before the Closing: (a) by mutual written consent of Seller and Buyer; (b) by Seller if any of the conditions in Section 7.1 has been neither waived by Seller nor satisfied by the time of the Closing; (c) by Buyer if any of the conditions in Section 7.2 has been neither waived by Buyer nor satisfied by the time of the Closing; (d) by Seller if there has been a material breach by Buyer of any of its representations, warranties or obligations contained in this Agreement that is not cured before the earlier of the time for Closing and five (5) Business Days after Buyer receives written notice of such breach; (e) by Buyer if there has been a material breach by Seller of any of its representations, warranties or obligations contained in this Agreement that is not be cured before the earlier of the time for Closing and five (5) Business Days after Seller receives written notice of such breach; or (f) by Seller or Buyer if the aggregate of (i) downward reductions in the Purchase Price under Sections 4.8 and 5.3(b) (before and exclusive of any other adjustments to the Purchase Price and (ii) the sum of the Asserted Defect Values on those Environmental Defects subject to Section 5.3(c) is equal to or exceeds five percent (5%) of the Purchase Price. (g) by Buyer if Preferential Rights are exercised with respect to (i) Real Property Interests with aggregate Allocated Values equal to or in excess of Thirty Million and No/100 United States Dollars or (ii) at least two (2) of such prospect areas (without regard to Allocated Values, if any, therefore), of the prospect areas described in Exhibit "T" hereto. In the event of (ii), Seller will have the option to present drilling opportunities of similar kind and nature to Buyer for the purpose of substituting prospect(s) for those lost to the preferential rights exercise. At Buyers sole discretion, Buyer may elect to accept such substitute prospect(s). If by the close of business on January 17, 2005 Buyer has not agreed to accept such substitute prospect(s) then Buyer shall provide written notice to Seller of Termination. 8.2 Effect of Termination.

(b) termination of this Agreement shall not affect or terminate the Confidentiality Agreement, which shall remain in full force and effect in accordance with its terms. -28- (c) if this Agreement is terminated for any reason whatsoever, Buyer shall promptly deliver to Seller all information furnished by or on behalf of Seller to Buyer or any of its Related Persons in connection with this Agreement or Buyer's investigation of the Subject Interests, together with all copies, extracts, excerpts or compilations of such information.

(e) if the parties jointly terminate this Agreement under Section 8.1 (a), if Buyer terminates this Agreement in accordance with Section 8.1(c), 8.1 (e), 8.1(f) or 8.1 (g) or if Seller terminates this Agreement for any reason other than as set forth in Section 8.1 (a), 8.1 (b) or 8.1 (d), then (1) the Deposit shall be refunded to Buyer and (2) neither party shall have any further liability or obligation to the other (except as provided in Section 8.2 (a)-(c)).

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. -31- 9.4 Procedure 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 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 a party or any of its Related Persons to give notice of a Third Person Claim as required by this Section 9.4(a) shall not relieve the other party of its defense and indemnity obligations under this ARTICLE 9 except to the extent such failure materially prejudices the other party'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, however, to the limitations set forth below in this Section 9.4(c)]. 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 without limitation, 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. -32- (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 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. (E) NOTWITHSTANDING ANY OTHER PROVISION, A CLAIM (LESS AND EXCEPT ANY CLAIM ARISING OUT OF RETAINED LIABILITIES) AGAINST SELLER (WHETHER FOR INDEMNITY, DEFENSE, BREACH OF THIS AGREEMENT OR OTHERWISE) SHALL NOT BE VALID OR ENFORCEABLE IF SELLER DOES NOT RECEIVE A PROPER CLAIM NOTICE FOR SUCH CLAIM WITHIN ONE (1) YEAR OF THE EFFECTIVE TIME. 9.5 Waiver 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 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 Person for which indemnification is provided in this Agreement or Seller's right to receive liquidated damages, including without limitation the Deposit, pursuant to the provisions of Section 8.2(d). 9.6 Records. As soon as reasonably practicable following the Closing, but in no event later than thirty (30) Days thereafter, Seller shall furnish to Buyer all 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 -33- and for making 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. 9.7 Confidentiality. The Confidentiality Agreement shall terminate effective as of the Closing only as to the Assets conveyed to Buyer. 9.8 Transfer of Operatorship. Except as prohibited by Law or applicable Contracts, Buyer shall, upon and after Closing, assume operatorship of (a) the Assets (or portions thereof) operated by Seller (or its designee) at 7:00 a.m. on February 1, 2005. Seller shall use reasonable efforts (which efforts shall not require Seller to incur any monetary or non-monetary obligations) to assist and cooperate with Buyer in connection with its efforts to secure operatorship of all Assets (or portions thereof). As promptly as practicable, Buyer shall file with all pertinent Governmental Authorities all pertinent change-of-operatorship forms and similar applications and instruments. (a) Strictly as an accommodation to Buyer, Seller agrees to operate the Subject Interests (limited to those for which either Buyer or Seller is the designated operator) for the account of the Buyer for a period not to extend past February 1, 2005, or such earlier date as may be mutually agreed to by Seller and Buyer. The date when Seller ceases to assist in the operation of the Subject Interests shall be referred to hereafter as the "Termination Date". While acting as operator on Buyer's behalf, Seller shall make good faith efforts to operate the Subject Interests in a manner substantially similar as they were being operated prior to Closing and in material compliance with all applicable laws, ordinances, rules and regulations, orders, terms of permits and authorizations by any Governmental Authority which may have jurisdiction over the Subject Interests. Seller's duties as operator for Buyer during this period shall include marketing (and applicable production reporting for the subject period) of produced oil and gas consistent with past field practices. In the case of an oil spill, blowout, explosion, fire, storm, hurricane or any other emergency situation, Seller shall have the right to make any necessary decisions or expenditures it deems appropriate in good faith as a prudent operator to operate the Subject Interests, and in addition to any other expenditures attributable to the period of time subsequent to the Effective Time, Buyer shall reimburse Seller for any such expenditures. In addition, from the date of Closing to the Termination Date, Seller shall endeavor to (i) assist Buyer in the training of personnel in the operation of the Subject Interests, and (ii) attempt to retain existing contract staff familiar with the operation of the Subject Interests (which endeavors shall not require Seller to incur any monetary or non-monetary obligations). (b) Seller further agrees to perform the accounting functions for the Subject Interests in a manner consistent with the performance of such accounting functions prior to the Effective Time for a period ending February 28, 2005, or such earlier date mutually agreed to by the Parties, at which date Buyer shall assume all accounting functions (the "Accounting Closing Date"). In order for Seller to perform the functions set forth in this Section, Buyer shall ensure that all revenues, proceeds and joint interests billings attributable to all production prior to 11:59 pm on the Accounting Closing Date shall continue to be made to Seller. From the date of Closing to the Accounting Closing Date, Seller shall endeavor to make royalty payments that are due, pay appropriate rental payments and handle revenue and expenditure accounting, as to the Subject -34- Interests. For purposes of this section, revenue accounting functions shall include disbursement of revenue proceeds to all working interest, royalty and overriding royalty owners as well as all rental and right of way payments. Seller will complete revenue accounting for hydrocarbons produced during the period between the Closing and the Accounting Closing Date, it being further understood that this will entail the Seller performing revenue settlement functions for such period after the Accounting Closing Date, but no longer than ninety (90) days after Closing, unless mutually agreed to by the parties. Expenditure accounting functions will include the payment of all expenditures and subsequent billing of same to all working interest owners. Seller will complete expenditure accounting functions for the calendar months falling between the Closing and Accounting Closing Date. With regard to Buyer's interest in the Subject Interests, Seller shall prepare and deliver to Buyer a detailed monthly statement of operating revenues and expenditures, including but not limited to operating costs, capital expenditures, production and ad valorem taxes (hereinafter referred to as "Net Cash Flow"). The form and content of such statement will be determined by the parties and will be issued as soon as practicable. From the Closing through Accounting Closing Date, Seller shall remit to Buyer the Net Cash Flow from the Subject Interests on a monthly basis. Such payments will be made by wire transfer as soon as practicable, but in no event later than forty-five (45) days following the month of production. (c) The Parties hereby further agree that Seller shall have no liability to Buyer, or any third party or Governmental Authority and Buyer shall release, defend, and indemnify Seller from, any Claims, actions, suits, proceedings, loss, costs, expenses, liability, property or environmental damage, or other damages to or incurred by Buyer, Seller, any Third Person or Governmental Authority which are attributable to, caused by or related to the use, ownership, operatorship or Seller's operation of the Subject Interests from the Closing to the Termination Date or accounting or other activities conducted by Seller from Closing to the Accounting Closing Date, and with respect to the revenue settlement functions after the Accounting Closing Date, regardless of the sole, joint or concurrent negligence (ordinary or gross, sole or partial), strict liability, regulatory liability, statutory liability, breach of contract, breach of warranty, or other fault or responsibility of Seller or any other person or party, except to the degree caused by the willful misconduct of Seller. (d) Seller shall not be obligated for any expenditures after the Effective Time, and shall be entitled to recover any charges and expenses incurred in the course of such operations or accounting efforts. Buyer, as of the Effective Time, assumes responsibility for all costs and expenses associated with ownership and operation of the Subject Interests, including but not limited to operations, maintenance, repairs, recompilations, reconditioning, modifications, capital expenditures, abandonments and salvage.

Subsequent to the month of January 2005 Buyer shall pay $15,000.00 per month to Seller for Seller's performance of accounting functions as described in subsection (b). This payment shall be made to Seller for each month in which Seller performs the functions set forth above in Section 9.8(b) until completion of the revenue settlement functions.

Any Transfer by Buyer (or any 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 thereof) of any obligations to Seller under this Agreement unless Buyer (or any successor or assign thereof) is expressly relieved or released thereof in writing by Seller in its sole and absolute discretion. 9.14 Survival of Representations, Warranties and Obligations.
