connection with, or otherwise relating to: (i) any inaccuracy of any representation or warranty of Buyer set forth in this Agreement; (ii) Buyer’s breach of, or failure to perform or satisfy, any of its covenants and obligations hereunder; and (iii) the Assumed Obligations, and (iv) the Assets (subject only to Seller’s indemnity obligations in Section 3.3(b) above), including, without limitation, the ownership or operation thereof and performance thereunder, or are attributable to environmental conditions whether or not such conditions existed prior to the Effective Time or arose subsequent to the Effective Time, REGARDLESS OF WHETHER ANY OF THE CLAIMS DESCRIBED IN CLAUSES (c)(i)-(c)(iv) ABOVE ARE ATTRIBUTABLE, IN WHOLE OR IN PART, TO THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE (BUT NOT SELLER’S WILLFUL MISCONDUCT), STRICT LIABILITY, LIABILITY WITHOUT FAULT, REGULATORY LIABILITY, STATUTORY LIABILITY, BREACH OF CONTRACT, BREACH OF WARRANTY OR OTHER FAULT OR RESPONSIBILITY OF SELLER, BUYER OR ANY OTHER PERSON OR PARTY. Notwithstanding anything to the contrary contained herein, Buyer’s general indemnification shall not cover, and there shall be excluded therefrom, any penalties or fines due with respect to the ownership or operation of the Assets prior to the Effective Time.

(d) Claims Procedures. Promptly upon a party becoming aware of any Claim with respect to which it believes it is entitled to indemnification hereunder, whether under this Section 3.3, Section 7.7, or the other provisions hereof, such party (an “Indemnified Party”) shall notify the other party (the “Indemnifying Party”) in writing of the existence and nature of such Claim, the identity of any third party claimants and a description of the damages and the amount thereof relating to such Claim (the “Claim Notice”). The Indemnified Party shall be responsible for the defense of any Claim unless the Indemnifying Party, upon reasonable notice, requests that the defense of a Claim be tendered to the Indemnifying Party. If:

(i) the defense of a Claim is so tendered and within ten (10) Business Days thereafter such tender is accepted by the Indemnifying Party; or

(ii) within ten (10) Business Days after the date on which the Claim Notice has been given pursuant to this Section 3.3(d), the Indemnifying Party shall acknowledge in writing to the Indemnified Party its obligation to provide an indemnity as provided in this Section 3.3 and assume the defense of the Claim;

then, except as hereinafter provided, the Indemnified Party shall not, and the Indemnifying Party shall, have the right to contest, defend, litigate or settle such Claim. The Indemnified Party shall have the right to be

11

represented by counsel at the Indemnified Party’s expense, subject to the limitations hereof, in any such contest, defense, litigation or settlement conducted by the Indemnifying Party. The Indemnifying Party shall lose its right to defend and settle the Claim if it shall fail to diligently contest and defend the Claim after written notice or demand by the Indemnified Party. So long as the Indemnifying Party has not lost its right and/or obligation to contest, defend, litigate and settle as herein provided, the Indemnifying Party shall have the exclusive right to contest, defend and litigate the Claim and shall have the exclusive right, in its discretion exercised in good faith, and upon the advice of counsel, to settle any such matter, either before or after the initiation of litigation, at such time and upon such terms as it deems fair and reasonable; provided, that at least five (5) Business Days prior to any such settlement, written notice of its intention to settle shall be given to the Indemnified Party and the Indemnified Party shall have consented thereto, which consent shall not be unreasonably withheld, conditioned or delayed. All expenses (including without limitation attorneys’ fees) incurred by the Indemnifying Party in connection with the foregoing shall be paid by the Indemnifying Party; provided that if the Indemnifying Party is the Seller, such expenses shall be paid or reimbursed to the Indemnified Party solely out of the Indemnity Amount and the Seller will have no obligation hereunder in excess of such amount. Notwithstanding the foregoing, in connection with any settlement negotiated by an Indemnifying Party, no Indemnified Party shall be required by an Indemnifying Party to (x) enter into any settlement that does not include as an unconditional term thereof the delivery by the claimant or plaintiff to the Indemnified Party of a full and complete release from all liability in respect of such claim or litigation, (y) enter into any settlement that attributes by its terms liability or wrongdoing to the Indemnified Party or (z) consent to the entry of any judgment that does not include as a term thereof a full dismissal of the litigation or proceeding with prejudice. No failure by an Indemnifying Party to acknowledge in writing its indemnification obligations under this Section 3.3 shall relieve it of such obligations to the extent they exist. If the Indemnifying Party fails to accept a tender of, or assume, the defense of a Claim pursuant to this Section 3.3(d), or if, in accordance with the foregoing, the Indemnifying Party shall lose its right to contest, defend, litigate and settle such a Claim or if there is a legal conflict, the Indemnified Party shall have the right, without prejudice to its right of indemnification hereunder, in its discretion exercised in good faith and upon the advice of counsel, to contest, defend and litigate such Claim, and may settle such Claim, either before or after the initiation of litigation, at such time and upon such terms as the Indemnified Party deems fair and reasonable; provided, that, the Indemnified Party will not settle such Claim without the prior written consent of the Indemnifying Party, which consent shall not be unreasonably withheld, conditioned or delayed. If, pursuant to this Section 3.3, the Indemnified Party so contests, defends, litigates or settles

12

a Claim for which it is entitled to indemnification hereunder as hereinabove provided, the Indemnified Party shall be reimbursed by the Indemnifying Party for the reasonable attorneys’ fees and other expenses of defending, contesting, litigating and/or settling the Claim which are incurred from time to time, forthwith following the presentation to the Indemnifying Party of itemized bills for said attorneys’ fees and other expenses; provided that if the Indemnifying Party is the Seller and the matter relates to a matter subject to indemnity by Seller pursuant to clause (a) of Section 3.3(b) (other than a breach of Sections 5.1(a), 5.1(b), 5.1(c) or 5.1(d) hereof), such expenses shall be reimbursable to the Indemnified Party solely out of the Indemnity Amount and the Seller will have no obligation hereunder in excess of such amount.

(e) Subrogation. Following full indemnification as provided for hereunder, the Indemnifying Party shall be subrogated to all rights of the Indemnified Party with respect to claims against third-parties (non-Seller Parties) relating to the matter for which indemnification has been made and the Indemnified Party agrees to use commercially reasonable efforts to cooperate with the Indemnifying Party in exercising such subrogation rights.

(f) Insured Losses; Recoveries from Third Parties. The amount of any damages for which indemnification is provided under this Section 3.3, Section 7.7, or the other provisions hereof shall be net of any duplicative amounts recovered by the Indemnified Party under insurance policies or from unaffiliated third parties with respect to such damages. If an Indemnified Party receives an amount under insurance coverage or from an unaffiliated third party with respect to damages at any time subsequent to any indemnification provided by an Indemnifying Party pursuant to this Section 3.3, Section 7.7, or the other provisions hereof, then such Indemnified Party shall promptly deliver such amount (up to the amount of the indemnification payment made to such Indemnified Party regarding such matter) to the Indemnifying Party; provided, however, that such Indemnified Party shall be entitled to retain the amount of any payments made or costs or expenses incurred in connection with obtaining such payment. The obligation created by this Section 3.3(f), Section 7.7, or the other provisions hereof is an obligation to make repayment in the event of and to the extent of a recovery from a third party and shall not delay an Indemnified Party’s right to repayment from the Indemnifying Party under this Section 3.3, Section 7.7, or the other provisions hereof.

(g) Characterization of Indemnification Payments. Buyer and Seller agree to treat any payment made under this Section 3.3, Section 7.7, or the other provisions hereof as an adjustment to the Purchase Price. Any indemnification hereunder will be determined on an after-tax basis (taking into account any actual tax benefits or detriments realized with respect to the damages for which the payment under this Section 3.3, Section 7.7, or the other provisions hereof is being made).

13

3.5 Assumed Obligations. Provided that the Closing occurs, Buyer hereby assumes all duties, obligations and liabilities of every kind and character with respect to the Assets or the ownership or operation thereof (other than the Retained Obligations), whether attributable to periods before or after the Effective Time, including, without limitation, those arising out of (a) the terms of the Leases or Surface Interests, or the Personal Property or Assets, (b) suspense accounts, to the extent transferred to Buyer, (c) ad valorem, property, severance and other similar taxes or assessments based upon or measured by the ownership of the Assets or the production therefrom attributable to any period on or after the Effective Time, (d) the condition of the Assets, regardless of whether such condition arose before or after the Effective Time, (e) obligations to properly plug and abandon or re-plug or re-abandon or remove xxxxx, flowlines, gathering lines or other facilities, equipment or other personal property or fixtures comprising part of the Assets, (f) obligations to restore the surface of the Assets and obligations to remediate or bring the Assets into compliance with applicable Environmental Laws (including conducting any remediation activities that may be required on or otherwise in connection with activities on the Assets) regardless of whether such obligations or conditions or events giving rise to such obligations arose, occurred or accrued before or after the Effective Time, (g) all obligations, liabilities, matters, events or conditions disclosed or described in the exhibits and schedules to this Agreement, regardless of whether such obligations, liabilities, matters, events or conditions or events giving rise to such obligations arose, occurred or accrued before or after the Effective Time, and (h) any other duty, obligation, event, condition or liability assumed by Buyer under the terms of this Agreement (collectively, the “Assumed Obligations”).

14

4. Taxes and Payables

4.1 Payment of Taxes. All real estate, use, ad valorem and personal property taxes and charges upon any of the Assets shall be prorated as of the Effective Time; provided that Buyer shall pay all such taxes attributable to the calendar year in which the Closing Date occurs to the extent due and payable after Closing, and at Closing the Purchase Price will be decreased by Seller’s pro rata share of such items for the period prior to the Effective Time (insofar as the same are based on the tax rates and methodology used or that was in effect on the Effective Time). If the actual amount of such items is not known as of the Closing Date and the final reconciliation of the Final Settlement Statement under Section 10.4, then Seller’s pro rata share of such items will be determined by using the rates and millages for the most recent year available and the assessed values for the calendar year immediately preceding the calendar year in which the Closing Date occurs, with appropriate adjustments for any known changes thereto. In no event shall the Final Settlement Statement be delayed pending determination of the proration of taxes pursuant to this Section 4.1. To the extent that any tax rates or method of calculation are changed after the Effective Time, even if the same will apply with regard to pre-Effective Time taxes, Buyer shall assume and be solely liable with regard thereto.

4.2 Production Taxes. Seller shall be responsible for all oil and gas production taxes, and any other similar taxes applicable to Hydrocarbons produced and saved from or attributable to its interest in the Leases, Xxxxx and Units prior to the Effective Time (excluding Stock Hydrocarbons), insofar as the same are based on the tax rates and methodology used or that was in effect on the Effective Time, and Buyer shall be responsible for all such taxes applicable to the Stock Hydrocarbons and all Hydrocarbons produced and saved from or attributable to the Leases, Xxxxx and Units from and after the Effective Time.

4.3 Occasional Sale of Assets. Both parties believe that the sale of the Assets is an occasional sale exempt from sales or use taxes. If any such taxes are assessed against the transaction, both parties will cooperate and use their commercially reasonable efforts (at no cost to Seller) to attempt to eliminate or reduce such taxes. If unsuccessful, Buyer shall be responsible for any such taxes. In that event, Buyer shall pay Seller any such state and local sales or use taxes, and Seller shall remit such amount to the appropriate taxing authority in accordance with applicable law. Any reasonable legal expenses incurred by Seller at Buyer’s request to reduce or avoid any of the aforementioned taxes attributable to Buyer, shall be paid or reimbursed by Buyer.

(a) entitles Seller to receive not less than the percentage set forth in Exhibit “A” as Seller’s Net Revenue Interest (as defined in the Preamble to Exhibits and Schedules attached hereto) of all Hydrocarbons produced, saved and marketed from or attributable to a Lease, Well or Unit, without reduction, suspension or termination of such interest throughout the productive life of such Lease, Well or Unit, except as specifically set forth in such Exhibit;

(b) obligates Seller to bear not greater than the percentage set forth in Exhibit “A” as Seller’s Working Interest of the costs and expenses relating to the maintenance, development and operation of a Lease, Well or Unit, all without increase throughout the productive life of such Lease, Well or Unit, except as specifically set forth in such Exhibit, and except to the extent of a proportionate increase in the Net Revenue Interest attributable thereto;

(c) is free and clear of all other liens and encumbrances on title, other than Permitted Encumbrances.

6.3 Permitted Encumbrances. The term “Permitted Encumbrances” means:

(a) lessor’s royalties, non-participating royalties, overriding royalties, division orders, sales, gathering, transportation and transportation-related services contracts containing customary terms and provisions, reversionary interests, and similar burdens if the net cumulative effect of such burdens does not operate to reduce the Net Revenue Interest in any Well to an amount less than the Net Revenue Interest set forth on Exhibit “A”, or increase the Working Interest of any Well from that set forth in Exhibit “A” without a corresponding increase in the Net Revenue Interest;

23

(b) the terms, conditions, restrictions, exceptions, reservations, limitations and other matters contained in (including, without limitation, any privileges, liens or security interests created by law or reserved in oil and gas leases for royalty, bonus or rental, or created to secure compliance with the terms of) the agreements, instruments and documents identified in, and all other matters described or referred to in, any of the Exhibits and Schedules hereto, or that otherwise create or reserve to Seller its interest in the Assets or any of them;

(c) Privileges or liens for taxes or assessments not yet due or delinquent or, if delinquent, are identified on Schedule 6.3(c) and are being contested in good faith in the normal course of business;

(d) preferential rights to purchase and required non-governmental third party consents to assignments and similar agreements identified in Schedule 5.1(k) with respect to which prior to Closing (i) waivers or consents are obtained from the appropriate parties or (ii) the appropriate time period for asserting such rights has expired without an exercise of such rights;

(e) all rights to consent by, required notices to, filings with, or other actions by Governmental Authorities in connection with the sale or conveyance of the Assets or interests therein, if the same are customarily obtained subsequent to such sale or conveyance;

(f) Title Defects or other deficiencies or irregularities (other than breaches of Seller’s special warranty of title) waived by Buyer in writing or not asserted on or before the expiration of the Examination Period;

(g) easements, rights-of way, servitudes, permits, surface leases, defects, irregularities, and other burdens, to the extent they do not materially interfere with the value of the Assets or the operation or use of the Assets as currently conducted by Seller;

(h) all laws, rules, regulations and orders of Governmental Authority having jurisdiction over the Assets, including, without limitation, rules and regulations governing production rates and allowables;

(i) vendors’, carriers’, warehousemen’s, repairmen’s, mechanics’, workmen’s, materialmen’s, construction or other like privileges or liens which have expired as a matter of law or arising by operation of law in the ordinary course of business or incident to the construction or improvement of any property in respect of obligations which are not yet due;

(j) any other privilege or lien, claim, charge, encumbrance, contract, agreement, instrument, obligation, defect, or irregularity affecting the Assets relating to obligations not yet in default, which is of the nature customarily accepted by prudent purchasers of oil and gas properties and which, individually or in the aggregate does not interfere materially with

24

the value or the use of the Assets, as currently used by Seller, does not prevent Buyer from receiving the proceeds of production from the Assets, does not reduce the Net Revenue Interest of any of the Xxxxx to less than the Net Revenue Interest set forth on Exhibit “A” and does not obligate Buyer to bear costs and expenses relating to the maintenance, development and operation of any of the Xxxxx in any amount greater than the Working Interest set forth on Exhibit “A” (unless the Net Revenue Interest for such Well is greater than the Net Revenue Interest set forth in Exhibit “A” in the same proportion as any increase in such Working Interest); and

(k) any privilege or lien or encumbrance to be released at or prior to Closing.

6.4 Notice of Title Defects; Title Defect Valuation.

(a) If Buyer discovers any Title Defect affecting an Asset, Buyer shall promptly notify Seller of such alleged Title Defect. To be effective, such notice (a “Title Defect Notice”) must (i) be in writing, (ii) be received 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 or Working Interest), (iv) identify the specific Asset or Assets affected by such Title Defect and (v) include the Title Defect Value, as reasonably determined by Buyer acting in good faith. Upon receipt of a timely Title Defect Notice, upon request by Seller, Buyer shall promptly deliver to Seller copies of all data, records, title reports, opinions and other information in Buyer’s possession or control bearing upon or relating to the alleged Title Defect and its determination of the Title Defect Value.

(b) The value attributable to each Title Defect (the “Title Defect Value”) shall be determined based upon the criteria set forth below:

(i) Subject to the limitation in subclause (vi) below, if the Title Defect is a privilege or lien upon an Asset, the Title Defect Value is the amount necessary to be paid to remove fully the privilege or lien from the affected Asset.

(ii) If the Title Defect asserted is that the Net Revenue Interest attributable to a Well is less than that stated in Exhibit “A” (and there is a corresponding and proportionate decrease in Working Interest), then the Title Defect Value is the product of the Allocated Value attributed to such Asset, multiplied by a fraction, the numerator of which is the difference between the Net Revenue Interest applicable thereto set forth in Exhibit “A” and the actual Net Revenue Interest, and the denominator of which is the applicable Net Revenue Interest stated in Exhibit “A”.

25

(iii) Subject to the limitation in subclause (vi) below, if the Title Defect represents an obligation, encumbrance, burden or charge upon the affected Asset (including any increase in Working Interest for which there is not a proportionate increase in Net Revenue Interest) and for which the economic detriment to Buyer is unliquidated, the amount of the Title Defect Value shall be determined by taking into account the Allocated Value of the affected Asset, the portion of the Asset affected by the Title Defect, the legal effect of the Title Defect, and the potential discounted economic effect of the Title Defect over the life of the affected Asset.

(iv) Subject to the limitation in subclause (vi) below, if a Title Defect does not adversely affect an Asset throughout the entire productive life of such Asset, such fact shall be taken into account in determining the Title Defect Value.

(v) The Title Defect Value of a Title Defect shall be determined without duplication of any costs or losses included in another Title Defect Value hereunder.

(vi) Notwithstanding anything herein to the contrary, in no event shall a Title Defect Value exceed the Allocated Value of the Xxxxx, Leases and other Assets affected thereby.

(vii) Such other factors as are reasonably necessary to make a proper evaluation.

(viii) Notwithstanding anything stated herein to the contrary, any Title Defect not asserted in writing by Buyer prior to the expiration of the Examination Period shall be deemed waived by Buyer for all purposes.

6.5 Remedies for Title Defects. Subject to Section 6.7, the following shall be Buyer’s sole and exclusive remedy with respect to Title Defects:

(a) Upon the receipt of a Title Defect Notice from Buyer asserting an alleged Title Defect, Seller shall have the option, but not the obligation, to attempt to cure such Title Defect at Seller’s sole cost at any time prior to the Closing.

(b) With respect to any alleged Title Defect that is not reasonably cured on or before the Closing, or the Title Defect Value for such Asset exceeds the Allocated Value for such Asset, Seller shall have the option, but not the obligation, to exclude the affected Asset from the Assets delivered at Closing and the Purchase Price shall be reduced by the Allocated Value of such affected Asset.

26

(c) With respect to each alleged Title Defect that is not reasonably cured on or before the Closing and the affected Asset has not been excluded from the transaction pursuant to Section 6.5(b), an amount equal to the Title Defect Value agreed upon in writing by Buyer and Seller acting reasonably shall be used to adjust the Purchase Price down at Closing, subject to Section 6.7.

(d) If Buyer and Seller have not agreed (i) on or before Closing upon the validity of an asserted Title Defect, or have not agreed on the Title Defect Value attributable thereto, or (ii) upon whether a Title Defect has been reasonably cured, then either party shall have the right to elect by written notice, delivered before or after Closing, to have the validity of such Title Defect, such Title Defect Value or the sufficiency of Seller’s cure determined by an Independent Expert pursuant to Section 8. In no event shall any adjustment to the Purchase Price be made to Seller or Buyer with respect to a Title Defect that is the subject of a dispute pending before the Independent Expert until such dispute is finally resolved as provided in Section 8 hereof. To the extent the Independent Expert is determining the validity of a Title Defect, Seller shall have ninety (90) days from the date the Independent Expert determines that a Title Defect exists to cure such Title Defect.

(e) Any Title Defect cured by Seller or for which Buyer receives a Purchase Price adjustment or payment pursuant to this Section 6.5, shall constitute a Permitted Encumbrance hereunder and under the Assignment.

6.6 Title Benefits.

(a) Subject to Section 6.7, Seller shall be entitled to an upward adjustment to the Purchase Price with respect to all Title Benefits of which Seller provides Buyer notice (a “Title Benefit Notice”) in writing prior to the expiration of the Examination Period in an amount (the “Title Benefit Value”) mutually agreed upon by the parties determined in accordance with the criteria set forth in Section 6.4(b). A party identifying a Title Benefit affecting the Assets shall promptly deliver such a Title Benefit Notice to the other party in the same form and including the same information as specified in Section 6.4(a) for a Title Defect Notice. The term “Title Benefit” shall mean Seller’s Net Revenue Interest in any Well that is greater than the Net Revenue Interest set forth in Exhibit “A”, or Seller’s Working Interest in any Well that is less than the Working Interest set forth in Exhibit “A” (without a proportionate decrease in the Net Revenue Interest).

(b) If, with respect to an asserted Title Benefit, the parties have not agreed on the validity of the Title Benefit or the Title Benefit Value attributable thereto on or before Closing, then either party shall have the right to elect by written notice to the other party to have the validity of the Title Benefit

27

and/or the Title Benefit Value determined by an Independent Expert pursuant to Section 8. Upon the final determination of the validity of the Title Benefit and the Title Benefit Value, the Purchase Price shall be upwardly adjusted therefor. In no event shall any adjustment be made with respect to a Title Benefit that is the subject of a dispute pending before the Independent Expert until such dispute is finally resolved as provided in Section 8 hereof.

6.7 Limitation of Remedies for Title Defects; Title Benefits. Notwithstanding anything to the contrary contained in this Agreement, if (a) the Title Defect Value for a given Title Defect, or the Title Benefit Value of a given Title Benefit, does not exceed $50,000 (to the extent an individual Title Defect does exceed this amount, a “Material Title Defect”), then no claim or adjustment to the Purchase Price shall be made for such Title Defect or Title Benefit, and (b) the aggregate net value (as determined above) of all uncured Material Title Defects and Title Benefits does not exceed $500,000.00 under this Agreement (the “Aggregate Title Deductible”), then no adjustment of the Purchase Price shall be made therefore; and to the extent they do exceed the Aggregate Title Deductible, then the Purchase Price shall only be adjusted (subject to the other limitations herein) to the extent the same exceeds the Aggregate Title Deductible.

7. Environmental Matters

7.1 Environmental Review.

(a) Buyer shall have the right to conduct an environmental review of the Assets prior to the expiration of the Examination Period (“Buyer’s Environmental Review”). Seller shall provide Buyer such access as it may reasonably request to the Assets (if operated by Seller) and the environmental data in Seller’s files for the Assets. With respect to Assets not operated by Seller, Seller agrees, at no cost or expense to Seller, to request that the operator of such Assets grant Buyer such access. Seller makes no representations or warranties whatsoever as to the accuracy, completeness or reliability of any such environmental information, and Buyer relies and depends on and uses any and all such environmental information, review or inspection exclusively and entirely at its own risk and without any recourse to Seller whatsoever.

(b) The cost and expense of Buyer’s Environmental Review shall be borne solely by Buyer. The scope of work comprising Buyer’s Environmental Review conducted at or upon the Leases, Units and Xxxxx shall not include any intrusive test or procedure without the prior written consent of Seller. Buyer shall (i) consult with Seller before conducting any work comprising such Buyer’s Environmental Review, (ii) perform all such work in a safe and workmanlike manner and so as to not unreasonably interfere with operations of the Assets and (iii) comply with all applicable laws, rules, and regulations of applicable Governmental Authority. Buyer shall be responsible for obtaining any third party consents that are required in

28

order to perform any work comprising Buyer’s Environmental Review. Buyer shall consult with Seller prior to requesting each such third party consent and Seller shall reasonably cooperate with Buyer in connection with obtaining such consent. Seller shall have the right to have a representative or representatives accompany Buyer at all times during Buyer’s Environmental Review, and Buyer shall give Seller notice not more than seven (7) days and not less than 48 hours before any visits by Buyer to the Assets, and Buyer shall seek and obtain Seller’s prior consent (which shall not be unreasonably withheld) before it enters upon the Assets. With respect to any samples taken in connection with Buyer’s Environmental Review, Buyer shall take split samples, providing one of each such sample, properly labeled and identified, to Seller. Buyer hereby agrees to release, defend, indemnify and hold harmless Seller Parties from and against all Claims arising from, out of or in connection with, or otherwise relating to, Buyer’s Environmental Review, REGARDLESS OF THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE (BUT NOT ANY SELLER PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), STRICT LIABILITY, REGULATORY LIABILITY, STATUTORY LIABILITY, BREACH OF CONTRACT, BREACH OF WARRANTY OR OTHER FAULT OR RESPONSIBILITY OF A SELLER PARTY OR ANY OTHER PERSON OR PARTY. Notwithstanding the foregoing and assuming that Buyer complies with the notice requirements of this Article 7, prior to Closing, Buyer shall have no indemnity obligation to Seller with respect to Buyer’s discovery of information that may lead to Claims arising from the condition of the Assets prior to Buyer’s Environmental Review.

(c) Unless otherwise required by applicable law, Buyer shall treat all matters revealed by Buyer’s Environmental Review, including, without limitation, any analyses, compilations, studies, documents, reports or data prepared or generated from such review (the “Environmental Information”), as confidential, and Buyer shall not disclose any Environmental Information to any Governmental Authority or other third party without the prior written consent of Seller except as hereafter provided or to the extent required by applicable law. Buyer may use the Environmental Information only in connection with the transactions contemplated by this Agreement. The Environmental Information shall be disclosed by Buyer to only those persons who need to know the Environmental Information for purposes of evaluating the transaction contemplated by this Agreement, and who agree to be bound by the terms of this Section 7.1(c). If Buyer or any third party to whom Buyer has provided any Environmental Information is requested, compelled or required to disclose any of the Environmental Information by a court or other Governmental Authority, or disclosure is otherwise required under applicable law, Buyer shall provide Seller with prompt notice sufficiently prior to any such disclosure so as to allow Seller to file for any protective order, or seek any

29

other remedy, as it deems appropriate under the circumstances. If this Agreement is terminated prior to the Closing, Buyer shall promptly deliver the Environmental Information, and all copies thereof and works based thereon, to Seller, which Environmental Information shall become the sole property of Seller; provided, however, that Buyer may retain copies thereof in the event of a dispute between Buyer and Seller arising from or relating to such termination. Buyer shall provide copies of the Environmental Information to Seller without charge. The terms and provisions of this Section 7.1(c) shall survive any such termination of this Agreement, notwithstanding anything to the contrary. In no event shall an Environmental Defect be the basis for adjusting the Purchase Price by an amount greater than the Allocated Value of the Asset(s) affected thereby.

(d) NORM. NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED HEREIN, BUYER ACKNOWLEDGES THAT SOME OILFIELD PRODUCTION EQUIPMENT LOCATED ON THE PROPERTIES MAY CONTAIN ASBESTOS AND/OR NATURALLY OCCURRING RADIOACTIVE MATERIAL (“NORM”). IN THIS REGARD, BUYER EXPRESSLY UNDERSTANDS THAT NORM MAY AFFIX OR ATTACH ITSELF TO THE INSIDE OF XXXXX, MATERIALS AND EQUIPMENT AS SCALE OR IN OTHER FORMS, AND THAT XXXXX, MATERIALS AND EQUIPMENT LOCATED ON THE PROPERTIES DESCRIBED HEREIN MAY CONTAIN NORM AND THAT NORM-CONTAINING MATERIALS MAY BE BURIED OR MAY HAVE BEEN OTHERWISE DISPOSED OF ON THE PROPERTIES COMPRISING OR SITUATED ON THE ASSETS. BUYER ALSO EXPRESSLY UNDERSTANDS THAT SPECIAL PROCEDURES MAY BE REQUIRED FOR THE REMOVAL AND DISPOSAL OF ASBESTOS AND NORM FROM THE PROPERTIES WHERE THEY MAY BE FOUND. BUYER SHALL, BY CLOSING ITS PURCHASE OF THE PROPERTIES, ASSUME ALL LIABILITY WHEN SUCH ACTIVITIES ARE PERFORMED.

7.2 Environmental Definitions.

(a) The term “Environmental Defect” shall mean, with respect to any given Asset, a material violation of Environmental Laws in effect as of the Effective Time in the jurisdiction in which such Asset is located.

(b) The term “Governmental Authority” shall mean any tribal authority, the United States and any state, county or parish, city and political subdivisions that exercises jurisdiction, and any agency, department, board, commission or other instrumentality thereof.

(c) The term “Environmental Laws” shall mean all laws, statutes, ordinances, court decisions, rules and regulations of any Governmental Authority pertaining to the environment as may be interpreted by applicable final, non-appealable court decisions or administrative orders.

30

(d) The term “Environmental Defect Value” shall mean, with respect to an Environmental Defect, the estimated costs and expenses to correct such Environmental Defect in the most cost effective manner reasonably available, consistent with Environmental Laws, taking into account that non-permanent remedies (such as mechanisms to contain or stabilize hazardous materials, including without limitation monitoring site conditions, natural attenuation, risk-based corrective action, institutional controls or other appropriate restrictions on the use of property, caps, dikes, encapsulation, leachate collection systems, etc.) may be the most cost effective manner reasonably available.

7.3 Notice of Environmental Defects. If Buyer discovers any alleged Environmental Defect affecting the Assets, Buyer shall promptly notify Seller of such alleged Environmental Defect. To be effective, such notice (an “Environmental Defect Notice”) must (a) be in writing, (b) be received prior to the expiration of the Examination Period, (c) describe the Environmental Defect in reasonable detail, including (i) the written conclusion of Buyer that an Environmental Defect exists and (ii) a citation of the Environmental Laws alleged to be violated and a summary of the related facts that substantiate such violation, (d) identify the specific Asset or Assets affected by such Environmental Defect, (e) indicate the procedures recommended to correct the Environmental Defect and (f) indicate Buyer’s reasonable good faith estimate of the Environmental Defect Value, for which Buyer would agree to adjust the Purchase Price in order to accept such Environmental Defect if Seller elected Section 7.4(c) as the remedy therefor. 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 all purposes and constitute an Assumed Obligation of Buyer at Closing. Upon receipt of a timely Environmental Defect Notice, upon request by Seller, Buyer shall promptly deliver to Seller copies of all data, records, reports, opinions and other information in Buyer’s possession or control bearing upon or relating to the alleged Environmental Defect and its determination of the Environmental Defect Value, including, without limitation, site plans showing the location of sampling events, boring logs and other field notes describing the sampling methods utilized and the field conditions observed, chain of custody documentation and laboratory reports.

7.4 Remedies for Environmental Defects. Subject to Sections 7.5 and 7.6, the following shall be Buyer’s sole and exclusive remedy with respect to alleged Environmental Defects:

(a) Upon the receipt of an Environmental Defect Notice from Buyer asserting an alleged Environmental Defect, Seller shall have the option, but not the obligation, to attempt to cure such Environmental Defect at any time prior to the Closing.

31

(b) With respect to any Material Environmental Defect (as defined below) that is not reasonably cured on or before the Closing, and the Environmental Defect Value for such Asset exceeds the Allocated Value for such Asset, either Party may have the option, but not the obligation, to exclude the affected Asset from the Assets delivered at Closing and the Purchase Price shall be reduced by the Allocated Value of such affected Asset.

(c) With respect to each alleged Environmental Defect that is not reasonably cured on or before the Closing and has not been excluded from the transaction pursuant to Section 7.4(b), an amount equal to the Environmental Defect Value agreed upon in writing by Buyer and Seller acting reasonably shall be the basis for an adjustment to the Purchase Price.

(d) If Buyer and Seller have not agreed (i) on or before Closing upon the validity of any asserted Environmental Defect, or if the parties have not agreed on the Environmental Defect Value therefor or (ii) upon whether an alleged Environmental Defect has been reasonably cured, then either party by written notice to the other party, delivered before or after Closing, shall have the right to elect to have the validity of the asserted Environmental Defect, the Environmental Defect Value for such Environmental Defect, or the sufficiency of Seller’s cure determined by an Independent Expert pursuant to Section 8. In no event shall any adjustment be made to the Purchase Price with respect to a Material Environmental Defect that is the subject of a dispute pending before the Independent Expert until such dispute is finally resolved as provided in Section 8 hereof. To the extent the Independent Expert is determining the validity of an Environmental Defect, Seller shall have ninety (90) days from the date the Independent Expert determines that an Environmental Defect exists to cure such Environmental Defect.

7.5 Limitation of Remedies for Environmental Defects. Notwithstanding anything to the contrary contained in this Agreement, (a) if the Environmental Defect Value for a given Environmental Defect does not exceed $50,000, then no adjustment to the Purchase Price shall be made for such Environmental Defect (each, a “Material Environmental Defect”), and (b) if the aggregate of all Environmental Defect Values exceeding $50,000 for uncured Material Environmental Defects not waived by Buyer does not exceed $500,000.00 under this Agreement (the “Aggregate Environmental Defect Deductible”), then no adjustment of the Purchase Price shall be made therefore; and to the extent such uncured Material Environmental Defects do exceed the Aggregate Environmental Defect Deductible, then the Purchase Price shall only be adjusted to the extent of such excess.

7.6 Post-Closing Environmental Indemnification by Buyer. Subject to Section 3.3(b), Buyer shall, with respect to the Assets and without regard to whether same arise or occur prior to or after the Effective Time (except as otherwise expressly provided below) assume and indemnify, defend and hold Seller Parties harmless from and against any and all Claims caused by, resulting from, or relating or incidental to all matters affecting health, safety and the

32

environment (excluding, however, fines and penalties assessed and owed by Seller as of the Effective Time with respect to ownership or operation of the Assets prior to the Effective Time) including without limitation Claims relating to:

(a) environmental pollution or contamination, including pollution or contamination of the soil, groundwater or air by Hydrocarbons, drilling fluid and other chemicals, brine, produced water, NORM or any other substance, and other violation of Environmental Laws;

(b) underground injection activities and waste disposal;

(c) clean-up responses, and the cost of remediation, control, assessment or compliance with respect to surface and subsurface pollution caused by spills, pits, ponds, lagoons or storage tanks;

(d) failure to comply with applicable land use, surface disturbance, licensing or notification requirements;

(e) disposal of any hazardous substances, wastes, materials and products generated by or used in connection with the ownership, development, operation or abandonment of any part of the Assets; and

(f) non-compliance with environmental or land use rules, regulations, demands or orders of appropriate Governmental Authorities,

REGARDLESS OF THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE (BUT NOT SELLER’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), BREACH OF CONTRACT, BREACH OF WARRANTY, STRICT LIABILITY, REGULATORY LIABILITY, STATUTORY LIABILITY OR OTHER FAULT OR RESPONSIBILITY OF SELLER OR ANY OTHER PERSON OR PARTY.

7.7 Condition of the Assets. Buyer specifically assumes the risk of the condition of the Assets and shall inspect the Assets prior to Closing, or, if such right of inspection is not exercised, shall be deemed to have waived such right. Buyer stipulates that 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, along with the facilities and equipment located thereon, having been used in connection with oil, gas and water production, treatment, storage and disposal activities, and may contain NORM, asbestos and other hazardous substances as a result of these operations. The generation, formation, or presence of NORM, asbestos or other hazardous substances in or on the Assets shall be the sole responsibility of Buyer, and Buyer and all future assignees and successors of Buyer shall defend, indemnify and hold Seller Parties harmless from and against any and all Claims in any way arising from, out of or in connection with, or otherwise relating to, the presence of NORM, asbestos or other hazardous substances, without regard to whether such NORM, asbestos or other hazardous substance was in place before or after the Effective Time, and REGARDLESS OF THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE (BUT NOT

33

SELLER’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), BREACH OF CONTRACT, BREACH OF WARRANTY, STRICT LIABILITY, REGULATORY LIABILITY, STATUTORY LIABILITY OR OTHER FAULT OR RESPONSIBILITY OF SELLER OR ANY OTHER PERSON OR PARTY.

7.8 Waiver. Buyer, with and upon Closing, waives for all purposes all objections associated with the environmental, physical and other condition of the Assets, unless raised by proper notice within the Examination Period, and Buyer (and on behalf of Buyer Parties and their successors and assigns) irrevocably waives any and all Claims they may have against the Seller Parties associated therewith.

8. Independent Experts

8.1 Selection of Independent Experts. Any disputes regarding Title Defects, Title Benefits, Title Defect Values, Title Benefit Values, Environmental Defects, Environmental Defect Values, the cure of Title Defects or Environmental Defects, any other matter for which Buyer or Seller is indemnified hereunder, and the calculation of the Final Settlement Statement, or revisions thereto, may, as herein provided, be submitted by a party, with written notice to the other party, to an independent expert (the “Independent Expert”), who shall serve as the sole and exclusive arbitrator of any such dispute. The Independent Expert, with regard to any disputes regarding Title Defect Values, Title Benefit Values, Environmental Defects, Environmental Defect Values, the cure of Title Defects or Environmental Defects, shall be selected upon his field of expertise with the mutual agreement of Buyer and Seller and shall have both knowledge and experience involving properties in the regional area in which the properties are located. If the parties are unable to agree on an Independent Expert, Seller shall appoint an arbitrator of its choice and Buyer shall appoint an arbitrator of its choice (each, a “Party Appointed Arbitrator”). The two Party Appointed Arbitrators shall in turn appoint a third to be the Independent Expert.

8.2 Procedures. Disputes to be resolved by an Independent Expert shall be resolved in accordance with mutually agreed procedures and rules and, failing such agreement, the arbitration proceedings shall be conducted pursuant to the then current Commercial Arbitration Rules of the American Arbitration Association (the “AAA”), but shall not be administered by the AAA.. The Independent Expert shall be instructed by the parties to resolve such dispute as soon as reasonably practicable in light of the circumstances but in any event within ninety (90) days for Title Defects or Title Benefits and within ninety (90) days for Environmental Defects. The decision and award of the Independent Expert shall be binding upon the parties 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.

8.3 Location of Proceeding. All proceedings under this Section 8 shall be conducted in Houston, Texas.

9. Additional Covenants

9.1 Operations Prior to Closing. After the date of this Agreement and prior to the Closing, as to any of the Assets operated by Seller, Seller shall use, operate and maintain the Assets in substantially the same manner in which they have been used, operated and maintained

34

prior to this Agreement. During the period from the Effective Time until Closing, Seller shall have no liability to Buyer for Claims sustained or liabilities incurred with respect to the Assets, REGARDLESS OF THE SOLE, JOINT, CONCURRENT OR COMPARATIVE NEGLIGENCE (BUT NOT SELLER’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), 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. After the date hereof and prior to Closing, Seller may (without Buyer’s consent) enter into agreements or transactions in relation to the Assets which (a) individually involve a reasonably anticipated cost of less than $50,000, or involve a reasonably anticipated cost which individually, or, in the aggregate, exceeds such amount, to the extent the same are set forth in the budget attached as Schedule 9.1 or (b) are entered into in the ordinary course of business, consistent with past practices. With Closing, Seller is relieved of and shall not be obligated for any expenditures attributable to periods after the Effective Time, and shall recover any such charges and expenses as part of the Closing Statement and Final Settlement Statement adjustments, as appropriate. Except with respect to those matters described above, if any material expenditure, contract or agreement is proposed or contemplated, Seller shall promptly submit such proposal to Buyer for concurrence with Seller’s recommendation. Buyer will make any required election under its independent evaluation and shall assume the cost and risk of any consequences which arise as a result of Buyer’s election to participate or Buyer’s failure to timely elect or election to not participate in or not approve an operation and not pay such expenditure, without regard to whether Closing occurs. Additionally, after the execution of this Agreement and prior to Closing, Seller shall have the right to make any changes, repairs or modifications to the Assets, and incur any related expenditure deemed necessary by Seller, to prevent or respond to an emergency involving serious risk of loss of or damage to life, property, or the environment. With regard to the preceding sentence, Seller shall notify Buyer as soon as possible of the emergency and Seller’s response thereto and shall have the right to cause or effect such expenditure or action with or without Buyer’s approval, and recover such costs in the Closing Statement or Final Settlement Statement adjustments, as appropriate. Prior to Closing, Seller shall consult with and advise Buyer regarding all material matters concerning the operation, management, and administration of the Assets, and before voting or making any election under any operating, unit, joint venture, or similar agreement. Furthermore, Seller will not, without the prior written consent of Buyer, (x) enter into any agreement or arrangement transferring, selling, or encumbering any of the Assets (other than sale of Sale Hydrocarbons in the ordinary course), (y) grant any preferential or other similar right to purchase any of the Assets or (z) enter into any new production sales contract not terminable on thirty (30) days’ notice or less. Promptly after execution of this Agreement, Seller shall notify the holders of the Consents of the transactions contemplated herein and request their consent. Buyer shall have the right to review and approve the form of such notices, such approval not to be unreasonably withheld. Buyer and Seller each agree to reasonably cooperate with efforts to obtain such required Consents.

35

9.2 Preferential Rights to Purchase.

(a) Notice. Promptly after execution of this Agreement, Seller shall use the Allocated Values set forth on Schedule 2.3 to provide each required Preferential Right notification.

(b) Third Party Exercise. If a third party gives valid and timely notice of its exercise of a Preferential Right to purchase any of the Assets, the affected Assets will not be sold to Buyer and the Purchase Price will be adjusted by the Allocated Value of the affected Assets. If Buyer has allocated a positive Allocated Value to the Preferential Right Asset, the Purchase Price will be reduced by the dollar amount of the positive allocation. If Buyer has allocated a negative Allocated Value to the Preferential Right Asset, the Purchase Price will be increased by the absolute value of the negative allocation. Buyer remains obligated to purchase the remainder of the Assets not affected by exercised Preferential Rights without reduction to the Purchase Price attributable to such unaffected Assets in accordance with the terms of this Agreement.

(c) Third Party Failure to Purchase. If a third party gives notice of its intent to exercise a Preferential Right to purchase any of the Assets, but does not close the purchase for any reason either before or within a reasonable time after Closing, or if a third party fails to give valid and timely notice of its exercise of a Preferential Right to purchase any of the Assets, then there shall promptly be an additional Closing between Seller and Buyer for such portion of the Assets pursuant to the terms of this Agreement, by which Seller will transfer the affected portion of the Assets to Buyer and Buyer will pay Seller that portion of the Purchase Price attributable thereto (or in the case of a negative allocation, Seller will refund the absolute value of the negative amount to Buyer) (in each case subject to adjustment in accordance with Section 2.4).
