CONSIDERATION

Section 3.01 Purchase Price. The total consideration for the purchase, sale and conveyance of the Assets to Buyer is Buyer’s payment to Seller of the sum of $575,000,000 (the “Purchase Price”) as adjusted pursuant to this Agreement (the “Adjusted Purchase Price”). The Adjusted Purchase Price shall be paid by Buyer to Seller at the Closing by means of a completed wire transfer to the account of Seller as designated by Seller to Buyer in writing prior to the Closing.

Section 3.02 Allocated Values. As of the date hereof, the Purchase Price is allocated among the fields, acreage (including Undeveloped Acreage) and physical assets (other than ▇▇▇▇▇) included in the Assets in the amounts set forth in Exhibit C-1. On or before 6 p.m. CDT on May 16, 2007, Buyer shall deliver to Seller a revised Exhibit C setting forth the Purchase Price allocated among the ▇▇▇▇▇ and the Future ▇▇▇▇▇ set forth on Exhibit C (as well as any additional Future Well to which Buyer desires to allocate value), physical assets (other than ▇▇▇▇▇) and the Undeveloped Acreage for each prospect described on such Exhibit (which value allocation shall be determined by Buyer using its reasonable judgment, shall be derived from Buyer’s allocated values provided on Exhibit C-1 and the total allocations per field shall not vary from the allocation for such field set forth on Exhibit C-1 by greater than 10%). The term “Allocated Values” as used in this Agreement shall mean the allocated values set forth in the revised Exhibit C delivered by Buyer to Seller pursuant to this Section 3.02. The Parties acknowledge that Seller is not making any representation or warranty, nor shall the Title Defect

mechanism set forth is Article 4 cover, any working interest, net revenue interest or number of acres set forth in the current or revised Exhibit C (it being understood by the Parties that, for purposes of the Title Defect mechanism the Parties shall rely on the working interests, net revenues interests and number of working interest net acres described in Exhibit A and Exhibit F).

ARTICLE IV
TITLE MATTERS

Section 4.01 Title Examination Period and Contractual Special Warranty.

(a) Commencing on the date following the date upon which Buyer delivers to Seller the revised Exhibit C pursuant to Section 3.02 (the “Title Examination Period”), Seller shall, subject to Section 6.01 (i) permit Buyer and/or its representatives to examine, at all reasonable times in Seller’s offices, all non-confidential and non-proprietary abstracts of title, title opinions, title files, ownership maps, lease files, assignments, division orders, operating records and agreements (including, without limitation, the Contracts) pertaining to the Assets insofar as same may now be in existence and in the possession of Seller, and (ii) subject to third party operator approval, permit Buyer and its representatives, at reasonable times and at Buyer’s sole risk, cost and expense, to conduct reasonable inspections of the Assets (other than environmental inspections which are covered by Section 4.11 hereof).

(b) If the Closing occurs, then effective as of the Closing Date, Seller warrants title to the Assets unto Buyer against every Person whomsoever lawfully claiming or to claim the same or any part thereof by, through or under Seller, but not otherwise, subject, however, to the Permitted Encumbrances; provided, however, that, except with respect to any liability of Seller for any claim asserted in writing by Buyer to Seller in accordance with Section 4.01(c) not later than six months after the Closing Date (the “Special Warranty Period”) for breach of such special warranty, such special warranty shall cease and terminate at the end of such Special Warranty Period. No warranty of title shall be contained in the Assignment. Said special warranty of title shall be subject to the further limitations and provisions of Section 4.01(c) and Section 4.06.

(c) With respect to any recovery by Buyer on the special warranty of title set forth in Section 4.01(b), the following shall apply:

(i) Prior to the expiration of the Special Warranty Period, Buyer shall furnish Seller a notice meeting the requirements of Section 4.03 setting forth any matters which Buyer intends to assert as a breach of Seller’s special warranty in Section 4.01(b). For all purposes of this Agreement, Buyer shall be deemed to have waived, and Seller shall have no further liability for, any breach of Seller’s special warranty that Buyer fails to assert in accordance with the forgoing prior to the expiration of the Special Warranty Period. Seller shall have a reasonable opportunity, but not the obligation, to cure any condition resulting in the alleged breach of Seller’s special warranty to title asserted by Buyer pursuant to this

Section 4.01(c)(i). Buyer agrees to reasonably cooperate with any attempt by Seller to cure any such condition giving rise to such alleged breach.

(ii) For purposes of Seller’s special warranty of title, the value of the Assets affected by such condition giving rise to an alleged breach of such special warranty of title shall be deemed to be the Allocated Value thereof, as adjusted herein. Recovery on Seller’s special warranty of title shall be limited to an amount (without any interest accruing thereon) equal to the reduction in the Purchase Price to which Buyer would have been entitled had Buyer asserted the condition giving rise to such breach of Seller’s special warranty of title as a Title Defect prior to Closing pursuant to Section 4.03, taking into account the limitations set forth in Section 4.06.

Section 4.02 Title Defects. An Asset shall be deemed to have a “Title Defect” if Seller has less than Defensible Title that is reasonably estimated to (i) require an expenditure in excess of $25,000 to remedy; or (ii) that is reasonably anticipated to reduce the value of such Assets by an amount in excess of $25,000. For purposes of this Agreement, the term “Defensible Title” means that subject to and except for the Permitted Encumbrances:

(a) with respect to any Subject Well, Seller is (i) entitled to receive not less than the percentage set forth in Exhibit A or Exhibit F hereto, as applicable, as the “NRI” or “Net Revenue Interest” for a given Subject Well of all Hydrocarbons produced, saved and marketed from such Subject Well, all without reduction, suspension or termination of such interest throughout the duration of the life of such Subject Well, except as specifically set forth in Exhibit A or Exhibit F hereto, as applicable, and (ii) obligated to bear the percentage of the costs and expenses relating to the maintenance, development and operation of such Subject Well not greater than the “WI” or “Working Interest” for such Subject Well shown in Exhibit A or Exhibit F hereto, as applicable (other than in connection with a corresponding increase in Net Revenue Interest), without increase throughout the duration of the life of such Subject Well, except as specifically set forth in Exhibit A or Exhibit F hereto, as applicable;

(b) with respect to any Undeveloped Acreage, Seller’s ownership thereof entitles it to the working interest net acres reflected therefor in Exhibit A Part 1 “Gross/Net Acres Re-Cap”; and

Notwithstanding the foregoing, the loss of or reduction of interest in any Subject Well or Lease following the Effective Time due to (x) any election or decision made by Seller in accordance with applicable joint operating agreements, or (y) expiration of the primary or secondary term of any lease, shall not constitute a Title Defect.

Section 4.03 Notice of Title Defects. If Buyer discovers any Title Defect, Buyer shall immediately notify Seller thereof, and in any event prior to the expiration of the Title Examination Period. To be effective, such notice shall be in writing and shall include (i) a

description of the alleged Title Defect(s), (ii) the Assets affected thereby, (iii) the value of the Assets subject to the alleged Title Defect(s) (which shall be the Allocated Value thereof, if specified, or based upon the Allocated Value of the affected Asset(s)), (iv) documentation sufficient to reasonably support the asserted Title Defect(s) and (v) the amount by which Buyer reasonably believes the value of the affected Assets are reduced by the alleged Title Defect(s) and the computations and information upon which Buyer’s belief is based. Subject to Buyer’s rights with respect to the special warranty of title set forth in Section 4.01(b) above, any matters that may otherwise constitute Title Defects but that are not specifically disclosed to Seller in accordance with the foregoing prior to the expiration of the Title Examination Period shall be deemed to have been waived by Buyer.

Section 4.04 Remedies for Title Defects. Seller shall have the option, but not the obligation, to attempt to cure any Title Defect. In the event that any Title Defect is not cured on or before Closing, Seller may, at its sole election:

(a) indemnify Buyer against all liability, loss, cost and expense resulting from such Title Defect (in an amount not to exceed the Allocated Value the Asset that is subject to such Title Defect) pursuant to the form of Title Indemnity Agreement set forth in Exhibit G hereto, in which event the Parties shall proceed to Closing and the Assets that are subject to such Title Defect shall be conveyed by Seller to Buyer subject to such Title Defect, with no payment or settlement at the Closing as a result of such Title Defect and no reduction or adjustment to the Purchase Price;

(b) credit Buyer pursuant to Section 8.02(b)(ii), and subject to Section 4.06, with the cost to cure such Title Defect agreed upon by Seller and Buyer (which agreement Buyer and Seller shall use good faith efforts to reach) or the such other amount agreed upon by Seller and Buyer (which agreement Buyer and Seller shall use good faith efforts to reach) as being the amount of the proportionate reduction in the value of such Assets resulting from such Title Defect (provided that (i) in the event that such Title Defect is the result of a discovery by Buyer that Seller owned, as of the Effective Time, a Net Revenue Interest in a Subject Well that is less than the Net Revenue Interest for such Subject Well set forth on Exhibit A or Exhibit F hereto, as applicable, then Buyer and Seller agree that the proportion of reduction to the Purchase Price shall be equal to the product of the Allocated Value for such Subject Well and the percentage reduction in such Net Revenue Interest as a result of such Title Defect, and (ii) in the event that such Title Defect is the result of a discovery by Buyer that Seller owned, as of the Effective Time, fewer working interest net acres of the Undeveloped Acreage than the working interest net acres reflected therefor in Exhibit A Part 1 “Gross/Net Acres Re-Cap”, then Buyer and Seller agree that the proportion of reduction to the Purchase Price shall be equal to the product of the Allocated Value for such Undeveloped Acreage, as applicable, and the percentage reduction in such working interest net acres as a result of such Title Defect), in which event the Parties shall proceed to the Closing and the Assets that are subject to such Title Defect shall be conveyed by Seller to Buyer subject to such Title Defect and Buyer shall pay to Seller the Purchase Price as so adjusted; or

(c) retain the Assets subject to such Title Defect and reduce the Purchase Price by an amount equal to the Allocated Value (or portion thereof allocable thereto) of such Assets, in which event the Parties shall proceed to the Closing and the Assets that are subject to such Title Defect shall be retained by Seller and Buyer shall pay to Seller the Purchase Price as so adjusted.

If Seller has elected pursuant to clause (b) above to reduce the Purchase Price by an agreed amount with respect to such Title Defect, but Buyer and Seller have failed to agree on such Title Defect Amount by the then scheduled Closing Date, then Seller shall elect to proceed with respect to such Title Defect under clause (a) or (c) above. In addition to the foregoing remedies, if the sum of all Title Defect Amounts, net of all Title Benefit Amounts, exceeds 10% of the Purchase Price, either Party shall have the right to terminate this Agreement.

Section 4.05 Title Benefits. Should either Party discover any Title Benefit on or before the end of the Title Examination Period, Seller shall have the right, and Buyer shall have the obligation, to notify the other Party thereof on or before the end of the Title Examination Period, which notice shall include (i) a description of the Title Benefit, (ii) the Assets affected, (iii) the Allocated Value of the Assets subject to the alleged Title Benefit(s), (iv) documentation sufficient to reasonably support the asserted Title Benefit(s) and (v) the amount by which the asserting Party reasonably believes the Allocated Value of the affected Assets are increased by the alleged Title Benefit(s) and the computations and information upon which such Party’s belief is based. With respect to each Subject Well affected by Title Benefits reported under this Section 4.05 (or which should have been reported by Buyer under this Section 4.05), the Purchase Price shall be increased by an amount equal to the product of the Allocated Value of the affected Subject Well multiplied by a fraction, the numerator of which is the actual Net Revenue Interest increase and the denominator of which is the Net Revenue Interest stated on Exhibit A or Exhibit F hereto, as applicable, and with respect to each Undeveloped Acreage, the Purchase Price shall be increased by an amount equal to the product of the Allocated Value for such Undeveloped Acreage multiplied by a fraction, the numerator of which is the actual working interest net acres for such Undeveloped Acreage and the denominator of which is the working interest net acres set forth on Exhibit A Part 1 “Gross/Net Acres Re-Cap” therefor (each of such amounts, the “Title Benefit Amount”).

Section 4.06 Limitations. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies available to Buyer for Title Defects if the sum of all Title Defect Amounts, net of all Title Benefit Amounts, does not exceed $1,000,000, (ii) in the event that the sum all Title Defect Amounts, net of all Title Benefit Amounts, exceeds $1,000,000, then any adjustments to the Purchase Price or other remedies provided by Seller pursuant to Section 4.05 shall be applicable only to the portion thereof that exceeds $1,000,000 and (iii) subject to Buyer’s rights with respect to the special warranty of title set forth in Section 4.01(b) above, Section 4.04 (as limited by this Section 4.06) shall, to the fullest extent permitted by applicable law, be the exclusive right and remedy of Buyer with respect to any Title Defect, any other title matter related to the Assets or Seller’s breach of Section 6.02 during the Title Examination Period and Buyer waives any and all other rights, rights at law or in equity with respect thereto.

Section 4.07 Preferential Rights To Purchase. Seller shall use its reasonable commercial efforts, but without any obligation to incur any cost or expense in connection therewith, to comply with all preferential right to purchase or similar rights relative to the sale of any of the Assets prior to the Closing set forth in Schedule 5.01(r) (the “Subject Preferential Rights”) but shall have no such obligation with respect to those agreements described in Schedule 4.07, if applicable. Seller shall deliver (by mail) notice of the transfer of any Asset subject to such Subject Preferential Rights in accordance with the applicable Contracts to the holders of such Subject Preferential Rights on or before the 5^th business day following the date upon which Buyer delivers to Seller the revised Exhibit C pursuant to Section 3.02. Seller shall promptly notify Buyer if any Subject Preferential Right is exercised or if the requisite period has elapsed without said right having been exercised. If a third party who has been offered an interest in any Asset pursuant to a Subject Preferential Right elects prior to the Closing to purchase all or part of such Asset pursuant to the aforesaid offer, the Asset or part thereof so affected will be eliminated from the Assets, the Purchase Price will be reduced by the Allocated Value attributable thereto and the Parties shall proceed to the Closing. Otherwise the Assets shall be conveyed to Buyer at Closing subject to any preferential right to purchase or similar right applicable to the transactions that has not been waived. If a third party elects to purchase all or a part of an interest in any Asset pursuant to a preferential right to purchase or similar right applicable to the transactions after the Closing Date, Buyer shall be obligated to convey said interest to such third party and shall be entitled to the consideration for the sale of such interest.

Section 4.08 Consents to Assignment. Seller shall use reasonable commercial efforts, but without any obligation to incur any cost or expense in connection therewith, to obtain prior to Closing all consents set forth in Schedule 5.01(c). Seller shall deliver (by mail) requests for such consents to the holders thereof on or before the 5^th business day following the date upon which Buyer delivers to Seller the revised Exhibit C pursuant to Section 3.02. If any such consent remains un-obtained and un-waived (by the passage of time or otherwise) as of the Closing, Seller shall have the right to elect to either (i) consider Seller to have less than Defensible Title with respect to such Asset and with such Asset being subject to the provisions of this Agreement for Assets with less than Defensible Title (and any Title Defect Amount being equal to the Allocated Value of such Asset), or (ii) treat such consent as a consent typically obtained after Closing with such Asset being subject to the provisions of Section 4.09 (other than the first sentence thereof).

Section 4.09 Post-Closing Consents. At the Closing, Seller shall execute and deliver to Buyer such assignments of Leases by Governmental Authorities as require consent to assignment that are typically obtained after Closing, on the forms required by such Governmental Authorities having jurisdiction thereof in addition to the assignment of such Leases pursuant to the Assignment, and Buyer shall pay to Seller, as part of the Purchase Price, the Allocated Value attributable to such Leases. With respect to unobtained consents to assignment for which Seller makes an election pursuant to Section 4.08(ii), the Assets affected thereby shall not be covered by the Assignment but Seller shall hold title to the affected Assets as Buyer’s nominee and Buyer shall pay to Seller, as part of the Purchase Price, the Allocated Value of such affected Assets. Seller and Buyer will use reasonable commercial efforts after Closing to obtain all such unobtained consents to assignment (including such consents from Governmental Authorities typically obtained after Closing), but Seller shall have no obligation to incur any costs or expenses in connection therewith. Until all of such unobtained consents are obtained, Seller

shall continue to hold title to the affected Assets as nominee for Buyer. If any such consent is finally denied, then Seller, at its sole option, may elect:

(a) to continue to hold title to the affected Assets as Buyer’s nominee pursuant to a nominee agreement containing the terms described in this Section 4.09, or

(b) to retain the affected Assets subject to such denied consent.

In the event Seller elects the option set forth in Section 4.09(b), then on or before the 30^th day following such election, (i) Buyer shall deliver to Seller all proceeds of production (net of all expenses, expenditures, capital expenses, royalties and other costs of operation incurred or paid by Buyer, but excluding mortgage interest and any burdens or encumbrances created by Buyer, all of which shall be released prior to any payment to Seller pursuant to Section 4.09(b)) attributable to the affected Assets from the Effective Time to the date of reassignment of such Assets from Buyer to Seller, (ii) Seller shall reimburse to Buyer the Allocated Value paid to Seller as part of the Purchase Price at the Closing for such affected Assets and (iii) Buyer shall execute any and all conveyances or other instruments necessary or desirable to fully vest title to such Assets in Seller and to otherwise accomplish the foregoing as requested by Seller.

Section 4.10 Allocation of Assumed Obligations and Overhead Costs. It being acknowledged and agreed that the Overhead Costs and Assumed Obligations are part of the consideration for the acquisition of the Assets, in the event any Assets are permanently removed from the transaction pursuant to Section 4.04(c), Section 4.07, Section 4.09 or Section 4.14(b) (the “Removed Assets”), (a) Overhead Costs payable by Buyer at Closing shall be reduced by the Retention Percentage allocable to the Removed Assets, and (b) Assumed Obligations specifically allocable solely to a Removed Asset pursuant to Exhibit E, shall be deemed eliminated from the definition of Assumed Obligations.

Section 4.11 Environmental Examination Period. Commencing on the date following the date upon which Buyer delivers to Seller the revised Exhibit C pursuant to Section 3.02 and ending on June 22, 2007 (the “Environmental Examination Period”), Seller shall, subject to third party operator and surface owner approval (which, upon Buyer’s request, Seller shall use its commercially reasonable effort to obtain but without any obligation to incur any cost or expense in connection therewith) and the provisions of 6.01 hereof, permit Buyer and its representatives, at reasonable times and at Buyer’s sole risk, cost and expense, to conduct reasonable environmental inspections of the Assets.

Section 4.12 Environmental Defect. An Asset shall be deemed to have an “Environmental Defect” if Buyer discovers that it is subject to a condition constituting a violation of Environmental Laws with respect to which the Lowest Cost Response therefor is reasonably estimated to require an expenditure in excess of $100,000. Notwithstanding the foregoing or anything else herein to the contrary, Buyer shall not be entitled to assert as a Environmental Defect hereunder any of the matters described as adverse or as a violation of any Environmental Law in the Environmental Report.

Section 4.13 Notice of Environmental Defects. If Buyer discovers any Environmental Defect, Buyer shall notify Seller thereof prior to the expiration of the Environmental

Examination Period. To be effective, such notice shall be in writing and shall include (i) a description of the alleged Environmental Defect(s), (ii) the Assets affected thereby, (iii) the value of the Assets subject to the alleged Environmental Defect(s) (which shall be the Allocated Value thereof, if specified, or based upon the Allocated Value of the affected Assets), (iv) documentation sufficient to reasonably support the asserted Environmental Defect(s) and (v) the amount which Buyer reasonably believes is the Lowest Cost Response to cure the alleged Environmental Defect(s) and the computations and information upon which Buyer’s belief is based. Any matters that may otherwise constitute Environmental Defects but that are not specifically disclosed to Seller in accordance with the foregoing prior to the expiration of the Environmental Examination Period shall be deemed to have been waived by Buyer.

Section 4.14 Remedies for Environmental Defects. Seller shall have the option, but not the obligation, to attempt to cure any Environmental Defect. In the event that any Environmental Defect is not cured on or before Closing, Seller may, at its sole election:

(a) indemnify Buyer against all liability, loss, cost and expense resulting from such Environmental Defect (in an amount not to exceed the Allocated Value of the Assets that are subject to such Environmental Defect), in which event the Parties shall proceed to Closing and the Assets that are subject to such Environmental Defect shall be conveyed by Seller to Buyer subject to such Environmental Defect, with no payment or settlement at the Closing as a result of such Environmental and no reduction or adjustment to the Purchase Price;

(b) credit Buyer pursuant to Section 8.02(b)(ii), and subject to Section 4.15, with an amount equal to the Lowest Cost Response to cure such Environmental Defect agreed upon by Seller and Buyer (which agreement Buyer and Seller shall use good faith efforts to reach), in which event the Parties shall proceed to the Closing and the Assets that are subject to such Environmental Defect shall be conveyed by Seller to Buyer subject to such Environmental Defect and Buyer shall pay to Seller the Purchase Price as so adjusted (such adjustment being herein referred to as the “Environmental Defect Amount”); or

(c) retain the Assets subject to such Environmental Defect and reduce the Purchase Price by an amount equal to the Allocated Value (or portion thereof allocable thereto) of such Assets, in which event the Parties shall proceed to the Closing and the Assets that are subject to such Environmental Defect shall be retained by Seller and Buyer shall pay to Seller the Purchase Price as so adjusted.

If Seller has elected pursuant to clause (b) above to reduce the Purchase Price by an agreed amount for the Lowest Cost Response to cure to such Environmental Defect, but Buyer and Seller have failed to agree on such Environmental Defect Amount by the then scheduled Closing Date, then Seller shall elect to proceed with respect to such Environmental Defect under clause (a) or (c) above. In addition to the foregoing remedies, if the sum of all Environmental Defect Amounts exceeds 10% of the Purchase Price, either Party shall have the right to terminate this Agreement.

Section 4.15 Limitations. Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies available to Buyer for Environmental Defects if the sum of all Environmental Defect Amounts does not exceed $1,000,000, (ii) in the event that the sum all Environmental Defect Amounts exceeds $1,000,000, then any adjustments to the Purchase Price or other remedies provided by Seller pursuant to Section 4.14 shall be applicable only to the portion thereof that exceeds $1,000,000, and (iii) Section 4.14 (as limited by this Section 4.15) shall, to the fullest extent permitted by applicable law, be the exclusive right and remedy of Buyer with respect to any Environmental Law or other environmental matter with respect to the Assets or Seller’s breach of any warranty with respect to Environmental Laws (including Section 5.(l) hereof) and Buyer waives any and all other rights, rights at law or in equity with respect thereto.

Without implying any obligation on Seller’s part to continue operating any Assets after the Closing, if Seller continues to operate any Assets following the Closing at the request of Buyer or any third party working interest owner, due to constraints of applicable joint operating agreement(s), failure of a successor operator to take over operations or other reasonable cause, such continued operation by Seller

Section 9.05 Document Retention.

(a) Subject to the provisions of Section 9.05(b), Buyer agrees, and will cause its assigns to agree, that the Documents shall be open for inspection by representatives of Seller at reasonable times and upon reasonable notice during regular business hours for a period of 6 years following the Closing Date (or for such longer period as may be required by law or Governmental Authorities), and that Seller may during such period at its expense make such copies thereof as it may reasonably request. Seller agrees, and shall cause its assigns to agree, that such documents and material as shall be retained by Seller and its assigns and that are related to the Assets (other than privileged, proprietary or confidential data or tax returns or other confidential tax information) shall be open for inspection by representatives of Buyer at reasonable times and upon reasonable notice during regular business hours for a period of 6 years following the Closing Date and that Buyer may during such period at its expense make such copies thereof as it may reasonably request.

(b) Destruction.

Section 9.06 Suspense Accounts. At Seller’s option, Seller shall have the right at or after Closing to transfer to Buyer all funds held by Seller in suspense related to proceeds of production and attributable to third parties’ interests in the Leases or Hydrocarbon production from the Leases, including funds suspended awaiting minimum disbursement requirements, funds suspended under division orders and funds suspended for title and other defects.

payment obligations relating thereto in accordance with all applicable laws, rules and regulations, and shall be liable for the payment thereof to the proper parties and such obligations shall become part of the Assumed Obligations.

Section 9.07 Imbalances. Effective as of the Closing, Buyer shall succeed to and assume the position of Seller with respect to the Imbalances set forth in Schedule 5.01(c), and as a result of the foregoing (a) Buyer shall be entitled to receive any and all benefits and shall bear any and all burdens of such Imbalances, and (b) Seller shall have no further rights or obligations with respect to such Imbalances.
