ARTICLE II

Purchase Price

Section 2.1. Purchase Price. In consideration of the sale of the Properties by Seller to Buyer, Buyer shall pay to Seller cash in the amount of $245,000,000 (the "Purchase Price"). The Purchase Price, as adjusted pursuant to this Article II and the other applicable provisions hereof, is herein called the "Adjusted Purchase Price".

Section 2.2. Accounting Adjustments.

(a) Subject to Section 2.2(b), appropriate adjustments shall be made between Buyer and Seller so that:

(i) all expenses (including all drilling costs, all capital expenditures, and all overhead charges under applicable operating agreements, and all other overhead charges actually charged by third parties) for work done in the operation of the Properties after the Effective Date will be borne by Buyer, and all proceeds (net of applicable production, severance, and similar Taxes) from the sale of oil, gas or other minerals produced from the Oil and Gas Properties after the Effective Date will be received by Buyer, and

(ii) all expenses for work done in the operation of the Properties before the Effective Date will be borne by Seller and all proceeds (net of applicable production, severance, and similar Taxes) from the sale of oil, gas or other minerals produced therefrom before the Effective Date will be received by Seller.

(b) It is agreed that, in making the adjustments contemplated by Section 2.2(a):

(i) oil which was produced from the Oil and Gas Properties and which was, on the Effective Date, stored in tanks located on the Oil and Gas Properties (or located elsewhere but used to store oil produced from the Oil and Gas Properties prior to delivery

(ii) to oil purchasers) and above pipeline connections shall be deemed to have been produced before the Effective Date (it is recognized that such tanks were not gauged on the Effective Date for the purposes of this Agreement and that determination of the volume of such oil in storage will be based on the best available data, which may include estimates) (with the stored crude oil produced before the Effective Date valued at the price for the month such oil was sold (or, if not sold yet, the price for the month in which such oil can reasonably be expected to be delivered to the purchaser thereof)),

(iii) ad valorem Taxes assessed with respect to a period which the Effective Date splits shall be prorated based on the number of days in such period which fall on each side of the Effective Date (with the day on which the Effective Date falls being counted in the period after the Effective Date), and

(iv) no consideration shall be given to the local, state or federal income tax liabilities of any party.

Section 2.3. Closing and Post-Closing Accounting Settlements.

(a) At or before Closing, the parties shall determine, based upon the best information reasonably available to them, the amount of the adjustments provided for in Section 2.2. If the amount of adjustments so determined which would result in a credit to Buyer exceed the amount of adjustments so determined which would result in a credit to Seller, Buyer shall receive a credit, for the amount of such excess, against the Purchase Price to be paid at Closing, and, if the converse is true, Buyer shall pay to Seller, at Closing (in addition to amounts otherwise then owed), the amount of such excess.

(b) On or before 90 days after Closing, Buyer and Seller shall review any additional information which may then be available pertaining to the adjustments provided for in Section 2.2, shall determine if any additional adjustments (whether the same be made to account for expenses or revenues not considered in making the adjustments made at Closing, or to correct errors made in such adjustments) should be made beyond those made at Closing, and shall make any such adjustments by appropriate payments from Seller to Buyer or from Buyer to Seller. Following such additional adjustments, no further adjustments to the Purchase Price shall be made under this Section 2.3.

(c) If a dispute arises under Section 2.3(b) with respect to any additional adjustments (an "Accounting Dispute") that the parties have been unable to resolve, then, at the written request of either Seller or Buyer (the "Request Date"), each of Seller and Buyer shall nominate and commit one of its senior officers to meet at a mutually agreed time and place not later than ten days after the Request Date to attempt to resolve same. If such senior officers have been unable to resolve such Accounting Dispute within a period of 30 days after the Request Date, any party shall have the right, by written notice to the other specifying in reasonable detail the basis for the Accounting Dispute, to resolve the Accounting Dispute by submission thereof to a nationally recognized independent public accounting firm commonly considered as one of the "Big 4" and reasonably acceptable to Seller and Buyer, which firm shall serve as sole arbitrator (the "Accounting Referee"). The scope of the Accounting Referee's engagement shall be limited to the resolution of the items described in the notice of the Accounting Dispute given in accordance with the foregoing and the corresponding calculation of the adjustments pursuant to Section 2.2. The Accounting Referee shall be instructed by the parties to resolve the Accounting

Dispute as soon as reasonably practicable in light of the circumstances but in no event in excess of 15 days following the submission of the Accounting Dispute to the Accounting Referee. The decision and award of the Accounting Referee shall be binding upon the parties as an award under the Federal Arbitration Act and final and nonappealable to the maximum extent permitted by law, and judgment thereon may be entered in a court of competent jurisdiction and enforced by any party as a final judgment of such court. The fees and expenses of the Accounting Referee shall be borne equally by Seller and Buyer.

Section 2.4. Payment of Adjusted Purchase Price. The Adjusted Purchase Price shall be paid to Seller as follows:

(a) Contemporaneously with the execution and delivery of this Agreement, Buyer shall tender to the Joint Account cash equal to $24,500,000 as a deposit (such amount, together with all interest earned thereon, the "Deposit"). The Deposit shall (i) be distributed to Seller and applied against the Adjusted Purchase Price owing by Buyer at the Closing pursuant to Section 2.4(b), (ii) distributed to Seller pursuant to Section 10.2 or (iii) distributed to Buyer pursuant to Section 10.2, as applicable.

(b) At Closing, Buyer shall pay to Seller by bank transfer in immediately available funds to the account designated by Seller an amount equal to the Adjusted Purchase Price less the Deposit.

(c) All cash payments by Buyer pursuant to this Section 2.4 shall be made in immediately available funds by confirmed wire transfer to a bank account or accounts designated by Seller or the Joint Account Holder, as applicable.

Section 2.5. Allocation of Purchase Price.

On or before the Closing Date, the Buyer and Seller shall agree in writing as to the allocation of the Adjusted Purchase Price (plus any fixed liabilities assumed by the Seller or to which the Properties are subject) among the Properties under the methodology required by Section 1060 of the Code. The Buyer and Seller shall report the transactions contemplated hereby on all Tax Returns, including, but not limited to Form 8594, in a manner consistent with such allocation. If, contrary to the intent of the parties hereto as expressed in this Section 2.5, any taxing authority makes or proposes an allocation different from the allocation determined under this Section 2.5, Buyer and Seller shall cooperate with each other in good faith to contest such taxing authority's allocation (or proposed allocation), provided, however, that, after consultation with the party adversely affected by such allocation (or proposed allocation), the other party hereto may file such protective claims or Tax Returns as may be reasonably required to protect its interests.

ARTICLE III

The Closing

The closing of the transactions contemplated hereby (the "Closing") shall take place (i) at the offices of Thompson & Knight LLP, Houston, Texas, at 10:00 a.m. (local Houston, Texas time) on October 11, 2007, or (ii) at such other time or place or on such other date as the parties hereto shall agree. The date on which the Closing is required to take place is herein referred to as the "Closing Date". All Closing transactions shall be deemed to have occurred simultaneously.

Section 4.4. Non-Contravention. Other than requirements (if any) that there be obtained consents to assignment (or waivers of preferential rights to purchase) from third parties, neither the execution, delivery, and performance by Seller of this Agreement and each other agreement, instrument, or document executed or to be executed by Seller in connection with the transactions contemplated hereby to which it is a party nor the consummation by it of the transactions contemplated hereby and thereby do and will (a) conflict with or result in a violation of Seller's Governing Documents, (b) conflict with or result in a violation of any provision of, or constitute (with or without the giving of notice or the passage of time or both) a default under, or give rise (with or without the giving of notice or the passage of time or both) to any right of termination, cancellation, or acceleration under, any bond, debenture, note, mortgage or indenture, or any material lease, contract, agreement, or other instrument or obligation to which Seller is a party or by which Seller or any of its properties may be bound, (c) result in the creation or imposition of any Lien upon the properties of Seller, or (d) violate any Applicable Law binding upon Seller, except, in the instance of clause (b) or clause (c) above, for any such conflicts, violations, defaults, terminations, cancellations or accelerations which would not, individually or in the aggregate, have a Material Adverse Effect.

Section 4.5. Approvals. Other than requirements (if any) that there be obtained consents to assignment (or waivers of preferential rights to purchase) from third parties, no

consent, approval, order, or authorization of, or declaration, filing, or registration with, any court or governmental agency or of any third party is required to be obtained or made by Seller in connection with the execution, delivery, or performance by Seller of this Agreement, each other agreement, instrument, or document executed or to be executed by Seller in connection with the transactions contemplated hereby to which it is a party or the consummation by it of the transactions contemplated hereby and thereby, except for such consents, approvals, orders, authorizations, declarations, filings or registrations which, if not obtained or made (as applicable), would not, individually or in the aggregate, have a Material Adverse Effect.

Section 4.6. Pending Litigation. Except as listed on Section 4.6 of the Seller's Disclosure Schedule, there are no Proceedings pending or, to Seller's Knowledge, threatened, against or affecting Seller or the Properties (including any actions challenging or pertaining to Seller's title to any of the Properties), or affecting the execution and delivery of this Agreement by Seller or the consummation of the transactions contemplated hereby by Seller. There are no outstanding judgments requiring Seller to take any action of any kind with respect to the Properties, or to which Seller or any of the Properties are subject, or by which they are bound or affected.

Section 4.7. Contracts.

(a) The Leases, Seller's interests in which comprise parts of the Oil and Gas Properties, and all other material contracts and agreements, licenses, Permits and easements, rights-of-way and other rights-of-surface use comprising any part of or otherwise relating to the Properties (such Leases and such material contracts, agreements, licenses, Permits, easements, rights-of-way and other rights-of-surface use being herein called the "Basic Documents"), are, in all material respects, in full force and effect and constitute valid and binding obligations of the parties thereto. Seller is not in breach or default (and no situation exists which with the passing of time or giving of notice would create a breach or default) of its obligations under the Basic Documents, and (to Seller's Knowledge) no breach or default by any third party (or situation which with the passage of time or giving of notice would create a breach or default) exists, to the extent such breach or default (whether by Seller or such a third party) could reasonably be expected to result in a Material Adverse Effect after the Effective Date. All payments (including all delay rentals, royalties, shut-in royalties and valid calls for payment or prepayment under operating agreements) owing under Basic Documents have been and are being made (timely, and before the same became delinquent) by Seller (and, where the non-payment of same by a third party could have a Material Adverse Effect after the Effective Date, have been and are being made, to Seller's Knowledge, by such third parties).

(b) Section 4.7 of the Seller's Disclosure Schedule is a list of all material contracts and agreements to which any of the Oil and Gas Properties are bound (other than the Existing Hedges), including (i) joint operating agreements, (ii) agreements with any Affiliate of Seller, (iii) any Production Sales Contracts, (iv) any agreement of Seller to sell, lease, farmout or otherwise dispose of any of its interests in the Oil and Gas Properties other than conventional rights of reassignment, (v) gas balancing agreements, (vi) exploration agreements, (vii) pooling, unitization or communitization agreement, (viii) area of mutual interest agreements, and (ix) agreements containing seismic licenses, Permits and other rights to geological or geophysical data and information directly or indirectly relating to the Oil and Gas Properties.

Section 4.8 Commitments, Abandonments or Proposals. Except as set forth in Section 6.3 of the Seller's Disclosure Schedule: (a) Seller has incurred no expenses, and has made no commitments to make expenditures in connection with the ownership or operation of the Properties after the Effective Date, other than routine expenses incurred in the normal operation of existing wells on the Oil and Gas Properties in accordance with generally accepted practices in the oil and gas industry; (b) Seller has not abandoned any wells (or removed any material items of equipment, except those replaced by items of materially equal suitability and value) on the Oil and Gas Properties since the Effective Date; and (c) no proposals are currently outstanding by Seller or other working interest owners to drill additional wells, or to deepen, plug back, or rework existing wells, or to conduct other operations for which consent is required under the applicable operating agreement, or to conduct any other operations other than normal operation of existing wells on the Oil and Gas Properties, or to abandon any wells, on the Oil and Gas Properties.

Section 4.9. Production Sales Contracts. There exist no agreements or arrangements for the sale of Hydrocarbons from the Oil and Gas Properties (including calls on, or other rights to purchase, production, whether or not the same are currently being exercised) other than (a) production sales contracts (in this Section, the "Scheduled Production Sales Contracts") disclosed in Section 4.9 of the Seller's Disclosure Schedule or (b) agreements or arrangements which are cancelable on 90 days notice or less without penalty or detriment. Seller is presently receiving a price for all production from (or attributable to) each Oil and Gas Property covered by a Scheduled Production Sales Contract as computed in accordance with the terms of such contract, and is not having deliveries of gas from any Oil and Gas Property subject to a Scheduled Production Sale Contract curtailed substantially below such property's delivery capacity. Seller has not received nor is Seller obligated to receive any advance, take-or-pay or other similar payments under production sales contracts that entitle the purchasers thereunder to recoup or otherwise receive deliveries of Hydrocarbons produced from or attributable to the Properties at any time at or after the Effective Date without payment therefor.

Section 4.10. Plugging and Abandonment. Except for wells listed in Section 4.10 of the Seller's Disclosure Schedule, there are no dry holes, or shut in or otherwise inactive wells, located on the Oil and Gas Properties or on lands pooled or unitized therewith, except for wells that have been plugged and abandoned, and except for wells drilled to depths not included within the Oil and Gas Properties or within units in which the Oil and Gas Properties participate which have never been completed in such depths.

Section 4.11. Permits. Seller has all Permits necessary or appropriate to own and operate the Properties as presently being owned and operated, except for such Permits the absence of which would not be reasonably expected to have a Material Adverse Effect, and such Permits are in full force and effect (and are freely transferable to Buyer or are subject to being routinely replaced by a license or Permit issued to Buyer as a successor owner of the Properties). Except as set forth in Section 4.11 of the Seller's Disclosure Schedule, Seller has not received written notice of any violations in respect of any Permits and, to Seller's Knowledge, there are no violations in respect of any Permit and no one has communicated to Seller that there are any violations in respect of any Permit, except for such violations which would not reasonably be expected to have a Material Adverse Effect.

Section 4.12. Payment of Expenses. All expenses (including all bills for labor, materials and supplies used or furnished for use in connection with the Properties, and all

(b) except where necessary to prevent the termination of a Lease or other material agreement governing Seller's interest in the Properties, propose the drilling of any additional

(c) wells, or propose the deepening, plugging back or reworking of any existing wells, or propose the conducting of any other operations which require consent under the applicable operating agreement, or propose the conducting of any other operations other than the normal operation of the existing wells on the Oil and Gas Properties, or propose the abandonment of any wells on the Oil and Gas Properties (and Seller agrees that it will advise Buyer of any such proposals made by third parties and will respond to each such proposal made by a third party in the manner requested by Buyer) or except in the ordinary course of business and consistent with past practices, voluntarily waive or release any material rights with respect to any Property or voluntarily relinquish Seller's position as operator with respect to any Property;

(d) sell, transfer or abandon any portion of the Properties other than items of materials, supplies, machinery, equipment, improvements or other personal property or fixtures forming a part of the Properties (and then only if the same is replaced with an item of substantially equal suitability, free of Liens, which replacement item will then, for the purposes of this Agreement, become part of the Properties);

(e) release (or permit to terminate), or modify or reduce its rights under, any Lease forming a part of the Oil and Gas Properties, or any other Basic Document, or enter into any new agreements which would be Basic Documents, or modify any existing production sales contracts or enter into any new production sales contracts, except contracts terminable by Seller with notice of 60 days or less;

(f) to the extent that Seller is not operator of any of the Properties, the obligations of Seller in this Section 6.3 shall be construed to require that Seller use Reasonable Best Efforts (without being obligated to incur any expense or institute any cause of action) to cause the operator of such Properties to take such action or render such performance within the constraints of the applicable operating agreements and other applicable agreements;

(g) keep in full force and effect insurance (including producing well and producing facilities coverages) comparable in amount and scope of coverage to that maintained by Seller for its Properties at the time of execution of this Agreement;

(h) promptly notify Buyer of each casualty loss about which Seller obtains Knowledge during the period between the date hereof and the Closing Date;

Section 6.5. Preferential Rights and Third Party Consents. Seller will request, from the appropriate parties (and in accordance with the documents creating such rights and/or requirements), waivers of the preferential rights to purchase, or requirements that consent to assignment be obtained, which are identified in Section 6.5 of the Seller's Disclosure Schedule. Seller shall have no obligation hereunder other than to so request such waivers (i.e., Seller shall have no obligation to assure that such waivers are obtained), and if all such waivers (or any other waivers of preferential rights to purchase or requirements that consent be obtained to assignment, even if the same are not listed on such Section 6.5) are not obtained, Buyer may treat any waiver which is not obtained as a matter which causes Seller's title to not be sufficient to meet the standards set forth in Article VIII; provided, however, that if the unobtained waiver is a waiver of a preferential right to purchase, and if both Buyer and Seller agree to this treatment of such matter (and agree upon an appropriate allocation of the Purchase Price), Seller will tender (at the agreed allocated portion of the Purchase Price) the required interest in the Property affected by such unwaived preferential right to purchase to the holder, or holders, of such right who have elected not to waive such preferential right to purchase, and if, and to the extent that, such preferential right to purchase is exercised by such party or parties, such interest in such Property will be excluded from the transaction contemplated hereby and the Purchase Price will be reduced by the agreed allocated portion of the Purchase Price attributable to such Property.

Section 7.10. Suspended Funds.

ARTICLE VIII

Due Diligence Examination

Section 8.1. Title Due Diligence Examination.

(a) From the date of this Agreement until 5:00 p.m. (local time in Houston, Texas) on October 1, 2007 (the "Examination Period"), Seller shall afford to Buyer and its authorized representatives reasonable access during normal business hours to the office, personnel and Records of Seller in order for Buyer to conduct a title examination as it may in its sole discretion choose to conduct with respect to the Oil and Gas Properties in order to determine whether Title Defects (as defined below) exist ("Buyer's Title Review"). Such Records shall include all abstracts of title, title opinions, title files, ownership maps, lease files, assignments, division orders, operating records and agreements, well files, financial and accounting records, geological, geophysical and engineering records, in each case insofar as same may now be in existence and in the possession of Seller, excluding, however, any information that Seller is prohibited from disclosing by bona fide, third party confidentiality restrictions; provided, that if requested by Buyer, Seller shall use its Reasonable Best Efforts to obtain a waiver of any such restrictions in favor of Buyer. The cost and expense of Buyer's Title Review, if any, shall be borne solely by Buyer.

(b) If Buyer discovers any Title Defect affecting any of the Oil and Gas Properties, Buyer shall notify Seller prior to the expiration of the Examination Period of such alleged Title Defect. To be effective, such notice ("Title Defect Notice") must (i) be in writing, (ii) be received by Seller prior to the expiration of the Examination Period, (iii) describe the Title Defect in reasonable detail (including any alleged variance in the Net Revenue Interest to the extent it is possible to estimate same), (iv) identify the specific Oil and Gas Property affected by such Title Defect, and (v) include the value of such Title Defect as determined by Buyer in good faith. Any matters that may otherwise constitute Title Defects, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, shall be deemed to have been waived by Buyer for all purposes. Upon the receipt of such effective Title Defect Notice from Buyer, Seller shall have the option, in addition to the remedies set forth in Section 8.1(c) (the "Remedies for Title Defects"), but not the obligation, to attempt to cure such Title Defect at any time prior to the Closing. The Oil and Gas Property affected by such uncured Title Defect shall be a "Title Defect Property". Notwithstanding the foregoing, Buyer retains the right to assert that any offered written undertaking by Seller is insufficient to constitute an actual cure of a Title Defect and Buyer possesses the right to reject such offered undertaking.

(c) With respect to each Title Defect that is not cured on or before the Closing, the Purchase Price shall be reduced, subject to this Article VIII, by the Title Defect Amount with respect to such Title Defect Property. The "Title Defect Amount" shall mean, with respect to a Title Defect Property, the amount by which such Title Defect Property is impaired as a result of the existence of one or more Title Defects, which amount shall be determined as follows:

(i) The Title Defect Amount with respect to a Title Defect Property shall be determined by taking into consideration the "Allocated Value" (as set forth in Exhibit 8.1(c) attached hereto) of the Oil and Gas Property subject to such Title Defect, the portion of the Oil and Gas Property subject to such Title Defect, and the legal effect of such Title Defect on the Oil and Gas Property affected thereby; provided, however, that: (A) if such Title Defect is in the nature of Seller's Net Revenue Interest in an Oil and Gas Property being less than the Net Revenue Interest set forth in Exhibit 8.1(c) hereto and the Working Interest remains the same, then the Title Defect Amount shall equal the Allocated Value for the relevant Oil and Gas Property multiplied by the percentage reduction in such Net Revenue Interest as a result of such Title Defect or (B) if such Title Defect is in the nature of a Lien, then the Title Defect Amount shall equal the amount required to fully discharge such Lien; and

(ii) If the Title Defect results from any matter not described in Section 8.1(c)(i), the Title Defect Amount shall be an amount equal to the difference between the value of the Title Defect Property affected by such Title Defect with such Title Defect and the value of such Title Defect Property without such Title Defect (taking into account the portion of the Allocated Value of the Title Defect Property).

(d) As used in this Section 8.1:

(i) "Defensible Title" means, as of the date of this Agreement and the Closing Date, with respect to the Oil and Gas Properties, such record title and ownership by Seller that:

(A) entitles Seller to receive and retain, without reduction, suspension or termination, not less than the percentage set forth in Exhibit 8.1(c) as Seller's Net Revenue Interest of all Hydrocarbons produced, saved and marketed from each Lease comprising such Oil and Gas Property as set forth in Exhibit 8.1(c), through plugging, abandonment and salvage of all wells comprising or included in such Oil and Gas Property, and except for changes or adjustments that result from the establishment of units, changes in existing units (or the participating areas therein), or the entry into of pooling or unitization agreements after the date hereof unless made in breach of the provisions of Section 6.3;

(B) obligates Seller to bear not greater than the percentage set forth in Exhibit 8.1(c) as Seller's Working Interest of the costs and expenses relating to the maintenance, development and operation of each Lease comprising such Oil and Gas Property, through plugging, abandonment and salvage of all wells comprising or included in such Oil and Gas Property, and except for changes or adjustments that result from the establishment of units, changes in existing units (or the participating areas therein), or the entry into of pooling or unitization

(D) is free and clear of all Liens, except Permitted Encumbrances;

(E) reflects that all consents to assignment, notices of assignment or preferential purchase rights which are applicable to or must be complied with in connection with the transaction contemplated by this Agreement, or any prior sale, assignment or the transfer of such Oil and Gas Property, have been obtained and complied with to the extent the failure to obtain or comply with the same could render this transaction or any such sale, assignment or transfer (or any right or interest affected thereby) void or voidable or could result in Buyer or Seller incurring any liability; and

(F) is free of imperfections in title which a reasonable and experienced purchaser of oil and gas properties would, in accordance with customary and generally accepted industry practices and norms, consider a defect in title and not normally waive.

(ii) "Permitted Encumbrances" shall mean (A) Liens for Taxes which are not yet delinquent or which are being contested in good faith and for which adequate reserves have been established; (B) normal and customary Liens of co-owners under operating agreements, unitization agreements, and pooling orders relating to the Oil and Gas Properties, which obligations are not yet due and pursuant to which Seller is not in default; (C) mechanic's and materialman's Liens relating to the Oil and Gas Properties, which obligations are not yet due and pursuant to which Seller is not in default; (D) Liens in the ordinary course of business consisting of minor defects and irregularities in title or other restrictions (whether created by or arising out of joint operating agreements, farm-out agreements, Leases and assignments, contracts for purchases of Hydrocarbons or similar agreements, or otherwise in the ordinary course of business) that are of the nature customarily accepted by prudent purchasers of oil and gas properties and do not decrease the Net Revenue Interest, increase the Working Interest (without a proportionate increase in the Net Revenue Interest) or materially affect the value of any property encumbered thereby; (E) all approvals required to be obtained from Governmental Entities that are lessors under Leases forming a part of the Oil and Gas Properties (or who administer such Leases on behalf of such lessors) which are customarily obtained post-closing; (F) preferential rights to purchase and consent to transfer requirements of any Person (to the extent same have been complied with in connection with the prior sale, assignment or the transfer of such Oil and Gas Property and are not triggered by the consummation of the transactions contemplated herein); (G) Liens under the Senior Credit Facility (provided such Liens are released at Closing); (H) Liens under the Existing Hedges (provided such Liens are released at Closing); and (I) conventional rights of reassignment normally actuated by an intent to abandon or release a Lease and requiring notice to the holders of such rights.

(iii) "Title Defect" shall mean any particular defect in or failure of Seller's ownership of any Oil and Gas Property: (A) that causes Seller to not have Defensible Title to such Oil and Gas Property, (B) that has attributable thereto a Title Defect Amount in excess of $50,000 and (C) regarding which a Title Defect Notice has been timely and

(iv) otherwise validly delivered. Notwithstanding any other provision in this Agreement to the contrary, the following matters shall not constitute, and shall not be asserted as, a Title Defect: (A) defects or irregularities arising out of lack of corporate authorization; (B) defects or irregularities that have been cured or remedied by the applicable statutes of limitation or statutes for prescription; (C) defects or irregularities in the chain of title consisting of the failure to recite marital status in documents or omissions of heirship Proceedings; (D) minor defects or irregularities in title which for a period of ten years or more have not delayed or prevented Seller (or Seller's predecessor) from receiving its Net Revenue Interest share of the proceeds of production and have not caused Seller to bear a share of expenses and costs greater than its Working Interest share from each Lease, unit or Well; and (E) defects or irregularities resulting from or related to probate Proceedings or the lack thereof which defects or irregularities have been outstanding for ten years or more. Further, notwithstanding any other provisions in this Agreement to the contrary, Buyer agrees that (i) if any of the following Leases have expired or expire prior to the Closing, such expiration will not be asserted as a Title Defect: Fidelity-Philadelphia Mineral Trust (expires May 2, 2007), JCM Jr. Minerals Co. No. 2 (expires September 1, 2007), Briscoe Ranch, Inc (2004 Lease which expires September 7, 2007 and Gloria A. Reeves (one third interest in 960 acres; and (ii) if an to the extent that Buyer asserts a Title Defect with respect to any undeveloped acreage included in the Properties, the Title Defect Value will be computed on the basis of $150 per acre.

(e) If Seller and Buyer are unable to reach an agreement as to whether a Title Defect exists or, if it does exist, the Title Defect Amount attributable such Title Defect, the provisions of Section 8.3 shall be applicable.

Section 8.2. Environmental Due Diligence Examination.

(a) Buyer shall have the right, or the right to cause an environmental consultant reasonably acceptable to Seller ("Buyer's Environmental Consultant"), to conduct an environmental review of the Properties prior to the expiration of the Examination Period ("Buyer's Environmental Review"). No less than 48 hours prior to the proposed commencement date of Buyer's Environmental Review, Buyer shall furnish Seller with an outline of the proposed scope of such review, including the locations of such activities. The cost and expense of Buyer's Environmental Review, if any, shall be borne solely by Buyer. No Person, other than Buyer's Environmental Consultant and Buyer's employees may conduct Buyer's Environmental Review. Seller shall have the right to have representatives thereof present to observe Buyer's Environmental Review conducted in Seller's offices or on Seller's properties. With respect to any samples taken in connection with Buyer's Environmental Review, Seller shall be permitted to take split samples. Buyer agrees to conduct Buyer's Environmental Review in a manner so as not to unduly interfere with the business operations of Seller and in compliance with all Applicable Laws, and Buyer shall exercise due care with respect to Seller's properties and their condition.

(b) Prior to the Closing, unless otherwise required by Applicable Law or Environmental Laws, Buyer shall (and shall cause Buyer's Environmental Consultant, if applicable, to) treat confidentially any matters revealed by Buyer's Environmental Review and any reports or data generated from such review (the "Environmental Information"), and Buyer shall not (and shall cause Buyer's Environmental Consultant, if applicable, to not) disclose any

(c) Environmental Information to any Governmental Entity or other third party without the prior written consent of Seller. Prior to the Closing, unless otherwise required by Applicable Law or Environmental Law, Buyer may use the Environmental Information only in connection with the transactions contemplated by this Agreement. If Buyer, Buyer's Environmental Consultant, if applicable, or any third party to whom Buyer has provided any Environmental Information become legally compelled to disclose any of the Environmental Information, Buyer shall provide Seller with prompt notice and Seller, at Seller's expense, may file any protective order, or seek any other remedy, as it deems appropriate under the circumstances. If this Agreement is terminated prior to the Closing, Buyer shall deliver the Environmental Information to Seller, which Environmental Information shall become the sole property of Seller. Upon Seller's written request to Buyer, Buyer shall provide copies of the Environmental Information to Seller without charge.

(d) If Buyer or Buyer's Environmental Consultant, if applicable, discovers any Environmental Defect (as herein defined) prior to the expiration of the Examination Period, Buyer shall notify Seller prior to the expiration of the Examination Period of such alleged Environmental Defect. To be effective, such notice (an "Environmental Defect Notice") must (i) be in writing; (ii) be received by Seller prior to the expiration of the Examination Period; (iii) describe the Environmental Defect in reasonable detail, including (A) the specific Properties affected by or associated with such Environmental Defect, and (B) the written conclusion of Buyer's Environmental Consultant, if applicable, that an Environmental Defect is believed to exist, which conclusion shall be reasonably substantiated by the factual data gathered in Buyer's Environmental Review; and (iv) set forth Buyer's good faith estimate of the Environmental Defect Value, including the basis for such estimate. Any matters that may otherwise constitute Environmental Defects, but of which Seller has not been specifically notified by Buyer in accordance with the foregoing, together with any environmental matter that does not constitute an Environmental Defect, shall be deemed to have been waived by Buyer for purposes of this Section 8.2. Upon the receipt of such effective notice from Buyer, Seller shall have the option, in addition to the remedy set forth in Section 8.4(c), but not the obligation, to attempt to cure such Environmental Defect at any time prior to the Closing, at the sole cost and expense of Seller. If Seller and Buyer are unable to reach an agreement as to whether an Environmental Defect exists or, if it does exist, the amount of the Environmental Defect Value attributable thereto, the provisions of Section 8.3 shall be applicable. Notwithstanding the foregoing, Buyer retains the right to assert that any offered written undertaking by Seller is insufficient to constitute an actual cure of an Environmental Defect and Buyer possesses the right to reject such offered undertaking.

(e) If any Environmental Defect described in a notice delivered in accordance with Section 8.2 is not cured on or before the Closing, then the Purchase Price shall be reduced, subject to Section 8.4, by the Environmental Defect Value of such Environmental Defect.

(f) As used in this Section 8.2:

(i) "Environmental Defect" shall mean, with respect to any given Property, a violation of Environmental Laws in effect as of the date hereof in the jurisdiction in which such Property is located, an obligation under Environmental Laws to complete immediately or promptly after the Closing any corrective action at the Property, or any Environmental Liability arising from or attributable to any condition, event, circumstance, activity, practice, incident, action, or omission existing or occurring prior

(ii) to the Closing Date, or the use, release, storage, treatment, transportation, or disposal of Hazardous Materials prior to the Closing Date, (A) regarding which an Environmental Defect Notice has been timely and otherwise validly delivered, (B) that has an Environmental Defect Value attributable thereto in excess of $50,000, and (C) is not otherwise disclosed in that certain report of Carr Environmental Group, Inc. dated as of January, 2006, a copy of which has heretofore been provided by Seller to Buyer.

(iii) "Environmental Defect Value" shall mean, (A) the net present value of the reasonably estimated costs and expenses to correct such Environmental Defect in the most cost effective manner reasonably available, consistent with Environmental Laws, or (B) the net present value of the amount of Environmental Liabilities reasonably believed will be incurred or required to be paid by Seller with respect thereto. The parties recognize that the calculation of an Environmental Defect Value may require the use of assumptions and extrapolations; however, it is acknowledged and agreed that any such assumptions and extrapolations will be consistent with the known factual information and reasonable in nature.

Section 8.3. Disputes Regarding Title Defects or Environmental Defects. If Seller and Buyer are unable to reach an agreement as to whether a Title Defect or an Environmental Defect exists, or if it does exist, the Title Defect Amount or Environmental Defect Value attributable to such Title Defect or Environmental Defect, or disputes relating to Post-Closing Defects pursuant to Section 8.4(c) (a "Defect Dispute"), each party shall have the right to submit a Defect Dispute to an independent expert (the "Independent Expert"), who shall serve as sole arbitrator. The Independent Expert shall be appointed by mutual agreement of Seller and Buyer from among candidates (including lawyers) with experience and expertise in the area that is the subject of such Defect Dispute, and failing such agreement, such Independent Expert for such Defect Dispute shall be selected in accordance with the Commercial Arbitration Rules of the AAA (the "Rules"). Defect Disputes to be resolved by an Independent Expert shall be resolved in accordance with mutually agreed procedures and rules and failing such agreement, in accordance with the Rules. The Independent Expert shall be instructed by the parties to resolve such Defect Dispute as soon as reasonably practicable in light of the circumstances. The decision and award of the Independent Expert shall be binding upon the parties as an award under the Federal Arbitration Act and final and nonappealable to the maximum extent permitted by law, and judgment thereon may be entered in a court of competent jurisdiction and enforced by any party as a final judgment of such court.

Section 8.4. Adjustments to Purchase Price for Defects.

(a) Notwithstanding anything to the contrary contained in this Agreement, no adjustment of the Purchase Price shall be made for Title Defects unless the aggregate of the Title Defect Amounts, as determined in accordance with this Agreement, equals or exceeds $1,000,000, in which event the Purchase Price shall be adjusted downward by the total of such Title Defect Amounts.

(b) Notwithstanding anything to the contrary contained in this Agreement, no adjustment of the Purchase Price shall be made for Environmental Defects unless the aggregate of the Environmental Defect Values, as determined in accordance with this Agreement, equals or exceeds $1,000,000, in which event the Purchase Price shall be adjusted downward by the amount such Environmental Defect Values exceed $1,000,000 in the aggregate.

(c) Notwithstanding anything herein to the contrary, if Seller is unable to cure a Title Defect or an Environmental Defect (a "Post-Closing Defect") on or prior to Closing, Seller shall have the option, by notice in writing to Buyer on or before Closing, to attempt to cure such Post-Closing Defect within the 90-day period commencing the Closing Date (the "Cure Period"). In such event, the transactions contemplated hereby will close as provided herein, but an amount equal to the applicable Title Defect Amount or Environmental Defect Value to which the Post-Closing Defect pertains shall be deducted from the Adjusted Purchase Price otherwise payable at Closing and paid into the Joint Account. The amount deposited into the Joint Account with respect to a Post-Closing Defect will remain therein until released as provided in Section 8.4(d).

(d) Buyer will act in good faith and reasonably cooperate with the Seller after the Closing to timely cure a Post-Closing Defect. If Seller and Buyer mutually agree that a Post-Closing Defect has been cured, then within two Business Days after such determination, the amount withheld in the Joint Account with respect thereto (together with any interest earned thereon) shall be released to Seller. If Seller and Buyer mutually agree that a Post-Closing Defect has been partially cured, then Seller and Buyer shall mutually determine the portion of the amount retained in the Joint Account with respect thereto (together with any interest earned thereon) that should be paid to Buyer to compensate it for the uncured portion thereof (together with interest earned thereon), and the remaining portion of such amount shall be released to Seller (together with any interest earned thereon). If Seller and Buyer mutually agree that a Post-Closing Defect has not been cured, then within two Business Days after such determination, the amount withheld in the Joint Account with respect thereto (together with any interest earned thereon) shall be released to Buyer. If, at the end of the Cure Period, Seller has been unable to cure a Post-Closing Defect (and there is no dispute as to whether or not it has been cured), the amount withheld in the Joint Account with respect thereto (together with any interest earned thereon) shall be released to Buyer. If, at the end of the Cure Period, Seller and Buyer are unable to agree whether there has been a satisfactory resolution of a Post-Closing Defect, then such disagreement shall be resolved as provided in Section 8.3.

Section 8.5. Buyer Indemnification. BUYER HEREBY INDEMNIFIES AND SHALL DEFEND AND HOLD SELLER, AFFILIATES THEREOF, AND ITS AND THEIR RESPECTIVE OWNERS, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, REPRESENTATIVES, CONTRACTORS, SUCCESSORS, AND ASSIGNS HARMLESS FROM AND AGAINST ANY AND ALL OF THE FOLLOWING CLAIMS ARISING FROM BUYER'S INSPECTING AND OBSERVING THE PROPERTIES: (I) CLAIMS FOR PERSONAL INJURIES TO OR DEATH OF EMPLOYEES OF BUYER, ITS CONTRACTORS, AGENTS, CONSULTANTS, AND REPRESENTATIVES, AND DAMAGE TO THE PROPERTY OF BUYER OR OTHERS ACTING ON BEHALF OF BUYER, EXCEPT FOR INJURIES OR DEATH CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SELLER, AFFILIATES THEREOF OR ITS OR THEIR RESPECTIVE EMPLOYEES, CONTRACTORS, AGENTS, CONSULTANTS, OR REPRESENTATIVES; AND (II) CLAIMS FOR PERSONAL INJURIES TO OR DEATH OF EMPLOYEES OF SELLER OR THIRD PARTIES, AND DAMAGE TO THE PROPERTY OF SELLER OR THIRD PARTIES, TO THE EXTENT CAUSED BY THE NEGLIGENCE, GROSS NEGLIGENCE, OR WILLFUL MISCONDUCT OF BUYER. TO THE EXTENT PROVIDED ABOVE, THE FOREGOING INDEMNITY INCLUDES, AND THE PARTIES INTEND IT TO INCLUDE, AN INDEMNIFICATION OF THE INDEMNIFIED PARTIES FROM AND

AGAINST CLAIMS ARISING OUT OF OR RESULTING, IN WHOLE OR PART, FROM THE CONDITION OF THE PROPERTY OR THE SOLE, JOINT, COMPARATIVE, OR CONCURRENT NEGLIGENCE OR STRICT LIABILITY OF ANY OF THE INDEMNIFIED PARTIES. THE PARTIES HERETO AGREE THAT THE FOREGOING COMPLIES WITH THE EXPRESS NEGLIGENCE RULE AND IS CONSPICUOUS.

Section 10.2. Effect of Termination. In the event of the termination of this Agreement pursuant to Section 10.1 by Seller, on the one hand, or Buyer, on the other, written notice thereof shall forthwith be given to the other party or parties specifying the provision hereof pursuant to which such termination is made, and this Agreement shall become void and have no effect, except that the agreements contained in this Article X, in Sections 7.4, 7.5 and 8.5 and in Articles XII and XIII shall survive the termination hereof.

ARTICLE XI

Survival of Representations, Warranties and Covenants; Indemnification

Section 11.1. Survival.

(a) The representations and warranties of the parties hereto contained in this Agreement shall terminate at Closing except that the representations made by Seller pursuant to Article IV, and the representations and warranties made by Buyer pursuant to Article V shall survive the Closing and shall remain in effect thereafter for the period that an Indemnified Party is entitled to indemnification based on a breach of such representation or warranty contained in this Article XI.

(b) No party hereto shall have any indemnification obligation pursuant to this Article XI or otherwise in respect of any representation, warranty or covenant unless (i) it shall have received from the party seeking indemnification written notice of the existence of the claim for or in respect of which indemnification in respect of such representation, warranty or covenant is being sought and (ii) if applicable, such notice is received on or before the Survival Date. Such notice shall set forth with reasonable specificity (i) the basis under this Agreement, and the facts that otherwise form the basis of such claim, (ii) the estimate (to the extent it is possible to estimate same) of the amount of such claim (which estimate shall not be conclusive of the final amount of such claim) and an explanation of the calculation of such estimate, including a statement of any significant assumptions employed therein, and (iii) the date on and manner in which the party delivering such notice became aware of the existence of such claim.

Section 11.2. Seller's Indemnification Obligations. Seller shall, on the date of Closing, agree (and, upon delivery to Buyer of the Assignment, shall be deemed to have agreed), subject to the limitations and procedures contained in this Article XI, following the Closing, to indemnify and hold Buyer, its Affiliates and its and their respective successors and permitted assigns and all of their respective stockholders, partners, members, managers, directors, officer, employees, agents and representatives harmless from and against any and all claims, obligations, actions, liabilities, damages or expenses (collectively, "Buyer's Losses"):

resulting from a breach of any of the representations or warranties made by Seller in Article IV (other than pursuant to Section 4.1, 4.2, 4.3, 4.4, 4.5, 4.17, or 4.19);

(a) resulting from a breach of any of the representations or warranties made by Seller in Section 4.19;

(b) arising out of claims for royalties, rentals, Taxes (or other loss burdens on production of any kind) attributable to Seller's ownership of the Properties before the Effective Date;

(d) resulting from a breach of any of the representations or warranties made by Seller in Section 4.1, 4.2, 4.3, 4.4, 4.5, or 4.17.

provided, however, that Seller's indemnification obligations for Buyer's Losses under Section 11.2(a), (b), and (c) shall expire on the one-year anniversary of the Closing Date (the "Survival Date"), except for Buyer's Losses for which a notice is received by Seller as provided in this Agreement prior to such date.

Section 11.3. Buyer's Indemnification Obligations. Buyer shall, on the date of Closing, agree (and, upon delivery to Buyer of the Assignment, shall be deemed to have agreed), subject to the limitations and procedures contained in this Article XI, following the Closing, to indemnify and hold Seller, its Affiliates and its and their respective successors and permitted assigns and all of their respective stockholders, partners, members, managers, directors, officer, employees, agents and representatives harmless from and against any and all claims, obligations, actions, liabilities, damages, costs or expenses, (collectively, "Seller's Losses"):

(a) resulting from any misrepresentation or breach of any warranty, covenant or agreement of Buyer contained in this Agreement or any certificate delivered by Buyer at the Closing; or

(b) relating to the Assumed Obligations;

provided, however, that Buyer's indemnification obligations for Seller's Losses under Section 11.3(a) shall expire on the Survival Date, except for Seller's Losses for which a notice is received by Buyer as provided in this Agreement prior to such date; and further provided, however, that Buyer's indemnification obligations for Seller's Losses under Section 11.3(b) shall not expire but shall remain in effect until such Assumed Obligations are fully satisfied.

Section 11.4. Net Amounts. Any amounts recoverable by any party pursuant to this Article XI with respect to any Buyer's Losses or Seller's Losses, as the case may be, shall be increased by any net tax costs to the Indemnified Party (Taxes incurred with respect to any indemnity payment less tax benefits resulting from the circumstances serving as the basis for such Buyer's Loss or Seller's Loss, as the case may be) and shall be decreased by (i) any net tax benefit to the Indemnified Party (tax benefits less Taxes incurred, as calculated above), and (ii) insurance proceeds or other amounts relating to such Buyer's Loss or Seller's Loss, as the case may be, paid to such Indemnified Party by any Person (other than any Affiliate of such Indemnified Party) not a party to this Agreement.

Section 11.5. Indemnification Proceedings. In the event that any claim or demand for which a party (an "Indemnifying Party"), would be liable to the another party under Section 11.2 or Section 11.3 (an "Indemnified Party") is asserted against or sought to be collected from an Indemnified Party by a third party, the Indemnified Party shall with reasonable promptness notify the Indemnifying Party of such claim or demand, but the failure so to notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Article XI, except to the extent the Indemnifying Party demonstrates that the defense of such claim or demand is materially prejudiced thereby. The Indemnifying Party shall have 30 days from receipt of the above notice from the Indemnified Party (in this Section 11.5, the "Notice Period") to notify the Indemnified Party whether or not the Indemnifying Party desires, at the Indemnifying Party's sole cost and expense, to defend the Indemnified Party against such claim or demand; provided, that the Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and not prejudicial to the Indemnifying Party. If the Indemnifying Party elects to assume the defense of any such claim or demand, the Indemnified Party shall have the right to employ separate counsel at its own expense and to participate in the defense thereof. If the Indemnifying Party elects not to assume the defense of such claim or demand (or fails to give notice to the Indemnified Party during the Notice Period), the Indemnified Party shall be entitled to assume the defense of such claim or demand with counsel of its own choice, at the expense of the Indemnifying Party. If the claim or demand is asserted against both the Indemnifying Party and the Indemnified Party and based on the advice of counsel reasonably satisfactory to the Indemnifying Party it is determined that there is a conflict of interest which renders it inappropriate for the same counsel to represent both the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be responsible for paying separate counsel for the Indemnified Party; provided, however, that the Indemnifying Party shall not be responsible for paying for more than one separate firm of attorneys to represent all of the Indemnified Parties, regardless of the number of Indemnified Parties. If the Indemnifying Party elects to assume the defense of such claim or demand, (i) no compromise or settlement thereof may be effected by the Indemnifying Party without the Indemnified Party's written consent (which shall not be unreasonably withheld) unless the sole relief provided is monetary damages that are paid in full by the Indemnifying Party and (ii) the Indemnifying Party shall have no liability with respect to any compromise or settlement thereof effected without its written consent (which shall not be unreasonably withheld).

Section 11.6. Indemnification Exclusive Remedy. Indemnification pursuant to the provisions of this Article XI shall be the exclusive remedy of the parties hereto for any misrepresentation or breach of any warranty, covenant or agreement contained in this Agreement or in any closing document executed and delivered pursuant to the provisions hereof or thereof, or any other claim arising out of the transactions contemplated by this Agreement.

Section 11.7. Limited to Actual Damages. The indemnification obligations of the parties pursuant to this Article XI shall be limited to actual Buyer's Losses or Seller's Losses, as the case may be, and shall not include incidental, consequential, indirect, punitive, or exemplary damages, provided that any incidental, consequential, indirect, punitive, or exemplary damages recovered by a third party (including a Governmental Entity, but excluding any Affiliate of any party) against a party entitled to indemnity pursuant to this Article XI shall be included in the damages recoverable under such indemnity.

Section 11.8. Indemnification Despite Negligence. It is the express intention of the parties hereto that each party to be indemnified pursuant to this Article XI shall be indemnified and held harmless from and against all Buyer's Losses or Seller's Losses, as the case may be, as to which indemnity is provided for under this Article XI, notwithstanding that any such damages arise out of or result from the ordinary, strict, sole, or contributory negligence of such party and regardless of whether any other party (including the other parties to this Agreement) is or is not also negligent. The parties hereto acknowledge that the foregoing complies with the express negligence rule and is conspicuous.
