Such allocation of value shall be attached to this Agreement as Schedule 2.3. The “Allocated Value” for any Asset equals the portion of such purchase price allocated to such Asset on Schedule 2.3, increased or decreased as described in Section 2.2. Except to the extent attributable to any specific Assets, any adjustments to the Purchase Price (including any indemnification payment treated as an adjustment to the purchase price for Tax purposes) other than the adjustments provided for in Sections 2.2(b), 2.2(c), 2.2(d), 2.2(e) and 2.2(f) shall, to the extent permitted by Section 1060 of the Code, be applied on a pro rata basis in proportion to the amounts set forth on Schedule 2.3 for all Assets for applicable Tax purposes only.

After Seller and Purchaser have agreed on the Allocated Values for the Assets, Seller will be deemed to have accepted such Allocated Values for purposes of this Agreement and the transactions contemplated hereby, but otherwise makes no representation or warranty as to the accuracy of such values. Seller and Purchaser agree (i) that the Allocated Values, as adjusted pursuant to this paragraph, shall be used by Seller and Purchaser as the basis for reporting asset

values and other items for purposes of all federal, state, and local Tax Returns, including Internal Revenue Service Form 8594 and (ii) that, except as required by applicable Law, neither they nor their Affiliates will take positions inconsistent with the Allocated Values (as adjusted pursuant to this paragraph) in any Tax Returns, in notices to Governmental Bodies, in audit or other proceedings with respect to Taxes, in notices to preferential purchase right holders, or in other documents or notices relating to the transactions contemplated by this Agreement without the consent of the other party hereto. Each party hereto shall promptly notify the other party in writing upon receipt of notice of any pending or threatened Tax audit or assessment challenging the Allocated Values, and neither party shall agree to any proposed adjustment to the Allocated Values by any Governmental Body without first giving to the other party prior written notice. However, nothing contained herein shall prevent either party from settling any proposed deficiency or adjustment by any Governmental Body based upon or arising out of the Allocated Values, and neither party shall be required to litigate any proposed deficiency or adjustment by any Governmental Body challenging such Allocated Values. Purchaser and Seller further agree that, on or before the Closing Date, they will mutually agree as to the further allocation of the Allocated Values included in Schedule 2.3 as to the relative portion of those values attributable to leasehold costs and depreciable equipment.

Section 3.4    Notice of Title Defects Defect Adjustments.

(a)    To assert a Title Defect, Purchaser must deliver claim notices to Seller (each a “Title Defect Notice”) on or before the date that is thirty (30) days from the date hereof (the “Title Claim Date”), except as otherwise provided under Sections 3.5 or 3.6. Each Title Defect Notice shall be in writing and shall include (i) a description of the alleged Title Defect(s), (ii) the Leases, Units or Wells affected by the Title Defect (each a “Title Defect Property”), (iii) the Allocated Values of each Title Defect Property, (iv) supporting documents reasonably necessary for Seller (as well as any title attorney or examiner hired by Seller) to verify the existence of the alleged Title Defect(s) and (v) the amount by which Purchaser reasonably believes the Allocated Values of each Title Defect Property are reduced by the alleged Title Defect(s) and the computations and information upon which Purchaser’s belief is based. Subject to Section 7.9, Purchaser shall be deemed to have waived for all purposes hereunder all Title Defects that were not included in a Title Defect Notice delivered to Seller on or before the Title Claim Date. To give Seller an opportunity to commence reviewing and curing alleged Title Defects, Purchaser agrees to provide Seller, on or before the end of each calendar week prior to the Title Claim Date, written notices of all Title Defects discovered by Purchaser during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Title Claim Date. Purchaser shall also promptly furnish Seller with written notice of any Title Benefit that is discovered by any of

Purchaser’s representatives, title attorneys, landmen or other title examiners while conducting Purchaser’s due diligence with respect to the Assets prior to the Title Claim Date.

(b)    Seller shall have the right, but not the obligation, to deliver to Purchaser with respect to each Title Benefit a written notice (a “Title Benefit Notice”) asserting such Title Benefit on or before the Title Claim Date. Each Title Benefit Notice shall include (i) a description of the Title Benefit(s), (ii) the Leases, Units or Wells affected by the Title Benefit (each a “Title Benefit Property”), (iii) the Allocated Values of the Title Benefit Property, (iv) supporting documents reasonably necessary for Purchaser (as well as any title attorney or examiner hired by Purchaser) to verify the existence of the alleged Title Benefit(s) and (v) the amount by which Seller reasonably believes the Allocated Values of those Units or Wells are increased by the Title Benefit, and the computations and information upon which Seller’s belief is based. Seller shall be deemed to have waived for all purposes hereunder all Title Benefits that were not included in a Title Benefit Notice delivered to Purchaser on or before the Title Claim Date.

(c)    Seller shall have the right, but not the obligation, upon delivering written notice to Purchaser, to attempt, at its sole cost, to cure or remove any Title Defects of which it has been advised by Purchaser on or before the expiration of sixty (60) days counted from and after the Title Claim Date (the “Cure Period”), unless the parties otherwise agree. If Seller has provided notice at or prior to the Closing Date of Seller’s intent to attempt to cure a Title Defect within the Cure Period, there shall be no reduction to the Purchase Price with respect to the Title Defect for purposes of Closing. If at the end of the Cure Period the Title Defect is not cured as agreed by Seller and Purchaser or if Seller and Purchaser cannot agree, and it is determined by the Title Arbitrator that such Title Defect is not cured at the end of the Cure Period, Seller shall elect one of the options set forth in Section 3.4(d)(i), or 3.4(d)(ii)(B) for such Title Defect, in which event the Purchase Price adjustment required in connection with the selected option under this Article 3 shall be made in the final statement of the Adjusted Purchase Price pursuant to Section 9.4(b). No action of Seller in electing or attempting to cure a Title Defect shall constitute a waiver of Seller’s right to dispute the existence, nature or value of, or cost to cure, the Title Defect.

(d)    In the event that (I) any Title Defect asserted by Purchaser in accordance with Section 3.4(a) is not waived by Purchaser and (II) Seller has not provided notice to Purchaser at or prior to the Closing Date of Seller’s intent to attempt to cure the given Title Defect, or Seller has provided such notice but the Title Defect is not cured before the expiration of the Cure Period, then Seller shall, at its sole election, elect to:

(i)    reduce the Purchase Price by the Title Defect Amount determined pursuant to Section 3.4(f) or 3.4(h);

(ii)    (A) at Closing, retain the Property that is associated with such Title Defect, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Property or (B) promptly after expiration of the Cure Period have Purchaser reconvey the Property that is associated with such Title Defect

to Seller, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Property, adjusted as provided in Section 2.2; or

(iii)    if applicable, terminate this Agreement pursuant to Article 10.

(e)    Remedies for Title Benefits. In the event that any Title Benefit asserted by Seller in accordance with Section 3.4(b) is not waived by Seller, then:

(i)    to the extent Purchaser and Seller agree on the Title Benefit Amount as calculated pursuant to Section 3.4(g), the Purchase Price shall be increased by such amount; and

(ii)    to the extent there is no agreement under Section 3.4(e)(i) on or before the Closing Date, the disagreement between Seller and Purchaser regarding the Title Benefit Property or the Title Benefit Amount, as applicable, shall be submitted to arbitration in accordance with Section 3.4(h).

(f)    The “Title Defect Amount” resulting from a Title Defect shall be determined as follows:

(i)    if Purchaser and Seller agree on the Title Defect Amount, then that amount shall be the Title Defect Amount;

(ii)    if the Title Defect is a lien, encumbrance or other charge which is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove the Title Defect from the Title Defect Property;

(iii)    if the Title Defect represents a discrepancy between (A) the Net Revenue Interest for any Title Defect Property and (B) the Net Revenue Interest as identified on Schedule 2.3, then the Title Defect Amount shall be the product of the Allocated Value of such Title Defect Property multiplied by a fraction, the numerator of which is the actual amount of the decrease in Net Revenue Interest from that identified on Schedule 2.3 and the denominator of which is the Net Revenue Interest as identified on Schedule 2.3; provided, however, that if the Title Defect does not affect the Title Defect Property throughout its entire life, the Title Defect Amount shall be reduced to take into account the applicable time period only;

(iv)    if the Title Defect represents an obligation, encumbrance, burden or charge upon or other defect in title to the Title Defect Property of a type not described in subsections (i), (ii) or (iii) above, then the Title Defect Amount shall be determined by taking into account the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the potential economic effect of the Title Defect over the life of the Title Defect Property, the values placed upon the Title Defect by Purchaser and Seller and such other factors as are necessary to make a proper evaluation;

(v)    if the Title Defect represents (I) a discrepancy between (A) the Net Revenue Interest for any Title Defect Property and (B) the Net Revenue Interest as identified on Schedule 2.3, and (II) an obligation, encumbrance, burden or charge upon or other defect in title to the Title Defect Property, then the Title Defect Amount shall be determined by applying both of subsections (iii) and (iv) to such Title Defect, without duplication; and

(vi)    notwithstanding anything to the contrary in this Article 3, the aggregate Title Defect Amounts attributable to the effects of all Title Defects upon any Title Defect Property shall not exceed the Allocated Value of such Title Defect Property.

(g)    The “Title Benefit Amount” resulting from a Title Benefit shall be the product of the Allocated Value of the Title Benefit Property multiplied by a fraction, the numerator of which is the actual amount of the increase in Net Revenue Interest from that identified on Schedule 2.3 and the denominator of which is the Net Revenue Interest identified on Schedule 2.3; provided, however, that if the Title Benefit does not affect the applicable Title Benefit Property throughout its entire life, the Title Benefit Amount shall be reduced to take into account the applicable time period only; provided further, that notwithstanding anything herein to the contrary, (i) in no event shall there be any adjustments to the Purchase Price for any individual Title Benefit for which the Title Benefit Amount does not exceed the Individual Defect Deductible (as defined below), and (ii) in no event shall there be any adjustments to the Purchase Price for Title Benefits unless the sum of the aggregate amount of all Title Benefit Amounts that exceed the Individual Defect Deductible, exceeds the Defect Deductible (as defined below), after which point Seller shall be entitled to adjustments to the Purchase Price or other available remedies under this Article 3 with respect to all Title Benefits in excess of the Individual Defect Deductible.

(h)    With respect to Title Defect Notices and Title Benefit Notices provided and received on or before the Title Claim Date, Seller and Purchaser shall attempt to agree on all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts on or before the day before the Closing Date, subject to Seller’s rights under Section 3.4(d)(ii). If Seller and Purchaser are unable to agree by that date, then subject to Section 3.4(c) and Seller’s rights under Section 3.4(d)(ii), Seller’s good faith estimate shall be used for purposes of calculating the Closing Payment pursuant to Section 9.4(a), and the Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 3.4(h). Likewise, if Seller has provided notice at or prior to the Closing Date of Seller’s intent to attempt to cure a Title Defect and by the end of the Cure Period, Seller and Purchaser have been unable to agree upon whether such Title Defect has been cured, or Seller has failed to cure any Title Defects which it provided notice that it would attempt to cure and Seller and Purchaser have been unable to agree on the Title Defect Amounts for such Title Defects, then the cure and/or Title Defect Amounts and Title Benefit Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 3.4(h), subject to Seller’s right under Section 3.4(d)(ii). There shall be a single arbitrator, who shall be a title attorney with at least ten

(10) years’ experience in oil and gas titles in the State of where the majority (as calculated based upon the Allocated Values of the Properties) of the affected Properties are located (as calculated based upon the Allocated Values of the Properties) as selected by mutual agreement of Purchaser and Seller within fifteen (15) days after the end of the Cure Period (or such other time as mutually agreed) and absent such agreement on the selection of the arbitrator, the arbitrator shall be selected by the Dallas, Texas office of the American Arbitration Association; provided, however, that in any case such attorney shall not have worked as an employee of or outside counsel for either Seller or Purchaser or any of their Affiliates during the 5-year period preceding the applicable arbitration or have any financial interest in the applicable dispute (such attorney, the “Title Arbitrator”). The arbitration proceeding shall be held in Dallas, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Title Arbitrator’s determination shall be made within twenty (20) days after submission of the matters in dispute and shall be final and binding upon both parties, without right of appeal. In making his determination, the Title Arbitrator shall be bound by the rules set forth in Sections 3.4(a), 3.4(b), 3.4(c), 3.4(d), 3.4(e), 3.4(f), 3.4(g) and 3.4(i) and may consider such other matters as in the opinion of the Title Arbitrator are necessary or helpful to make a proper determination. Additionally, the Title Arbitrator may consult with and engage disinterested third parties to advise the arbitrator, including petroleum engineers. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts submitted by either party hereto and may not award damages, interest or penalties to either party hereto with respect to any matter. Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case. Each party hereto shall bear one-half of the costs and expenses of the Title Arbitrator.

(i)    Notwithstanding anything herein to the contrary, (y) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual Title Defect for which the Title Defect Amount does not exceed Fifty-five Thousand Dollars ($55,000) (the “Individual Defect Deductible”); and (z) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for Title Defects unless the sum of (I) the aggregate amount of all Title Defect Amounts for Title Defects covered by Section 3.4(d)(i) that exceed the Individual Defect Deductible, plus (II) the aggregate amount of all Environmental Liabilities covered by Section 4.4(a) that exceed the Individual Defect Deductible, exceeds a deductible in an amount equal to two percent (2%) of the Purchase Price (the “Defect Deductible”), after which point Purchaser shall be entitled to adjustments to the Purchase Price or other available remedies under this Article 3 with respect to all Title Defects in excess of the Defect Deductible, subject to the Individual Defect Deductible and Seller’s elections under Section 3.4(d). The provisions of this Section 3.4(i) shall not apply to Title Defects relating to consent to assignment and preferential rights to purchase which shall be handled or treated under Section 3.5. The Allocated Value of any Property retained by Seller in accordance with Section 3.4(d)(ii) may not be used in meeting the Defect Deductible.

Section 3.5    Consents to Assignment and Preferential Rights to Purchase.

Seller shall use commercially reasonable efforts to promptly prepare and send (i) notices to the holders of any required consents to assignment of any Assets to request such consents and (ii) notices to the holders of any applicable preferential rights to purchase any Asset requesting waivers of such preferential rights to purchase, in each case of which Seller has knowledge. The consideration payable under this Agreement for any particular Assets for purposes of preferential purchase right notices shall be the Allocated Value for such Assets. Seller shall use commercially reasonable efforts to cause such consents and waivers of preferential rights to purchase (or the exercise thereof) to be obtained and delivered prior to Closing. Purchaser shall cooperate with Seller in seeking to obtain such consents to assignment and waivers of preferential rights. Notwithstanding anything contained herein to the contrary, Seller shall have no liability for failure to obtain such notices.

(a)    Consents. Seller shall notify Purchaser in writing at least five (5) Business Days prior to Closing of all required third-party consents to the assignment of the Assets to Purchaser which have not been obtained and the Assets to which they pertain. In no event shall there be included in the Conveyances at Closing any Asset subject to a consent requirement that provides that transfer of the Asset without consent will result in a termination or other material impairment of any rights in relation to such Asset (such consent, a “Required Consent”). In cases where the Asset subject to such a Required Consent is a Contract and Purchaser is assigned the Properties to which the Contract relates, but the Contract is not transferred to Purchaser due to the unwaived consent requirement, Seller shall continue after Closing to use commercially reasonable efforts to obtain such consent so that such Contract can be transferred to Purchaser upon receipt of such consent. In cases where the Asset subject to such a Required Consent is a Property and the third-party consent to the sale and transfer of the Property is not obtained prior to the Closing Date, Purchaser may elect to treat the unsatisfied Required Consent as a Title Defect by giving Seller notice thereof in accordance with Section 3.4(a), except that such notice must be given at least three (3) Business Days prior to the Closing Date; provided, however, the Allocated Value for such Property may not be used in meeting the Defect Deductible, and Seller may elect to cure such unsatisfied consent under Section 3.4(c), in which event the provisions of Section 3.4(c) shall apply (provided the affected Asset shall be excluded from the Assets for purposes of Closing (unless otherwise agreed by Seller and Purchaser)). If an unsatisfied Required Consent with respect to which a Purchase Price adjustment is made under Section 3.4 is subsequently satisfied prior to the date of the final adjustment to the Purchase Price under Section 9.4(b), Seller shall receive an additional upward adjustment to the Purchase Price in the final adjustments made under Section 9.4(b) equal to the amount of the previous reduction in the Purchase Price on account of such Required Consent and the provisions of this Section 3.5 shall no longer apply except for the assignment made under the next sentence. Within two days of the date on which the final statement of the Adjusted Purchase Price is finally determined, whether by agreement between Seller and Purchaser or the determination of an Independent Expert under Section 9.4(b) (or both), Seller shall assign to Purchaser using the form attached as Exhibit B, to the extent previously unassigned, each Property subject to a Required Consent that was subsequently satisfied prior to the date of the final adjustment of the Purchase Price under Section 9.4(b).

(b)    Exercised Preferential Rights to Purchase. If any preferential right to purchase any Property is exercised prior to Closing, the Property transferred to a third party as a result of the exercise of such preferential right shall be treated as if it was subject to a Title Defect resulting in the complete loss of title and the Purchase Price shall be reduced under Section 2.2(b) by the Allocated Value for such Property (proportionately reduced if the preferential right affects only a portion of such Property). Seller shall retain the consideration paid by the third party pursuant to the exercise of such preferential right; provided, however, the adjustment made under this Section 3.5(b) for such Property may not be used in meeting the Defect Deductible.

Section 3.6    Casualty or Condemnation Loss.

Subject to the provisions of Sections 8.1(e) and 8.2(e), if, after the date of this Agreement but prior to the Closing Date, any portion of the Assets is destroyed by fire or other casualty or is taken in condemnation or under right of eminent domain, and the loss as a result of such individual casualty or taking exceeds Seventy-five Thousand Dollars ($75,000), Seller shall elect by written notice to Purchaser prior to Closing either (i) to cause the Assets affected by any casualty to be repaired or restored prior to Closing to at least its condition prior to such casualty, at Seller’s sole cost (without an adjustment to the Purchase Price pursuant to Section 2.2 or otherwise), as promptly as reasonably practicable (which work may extend after the Closing Date), or (ii) unless such casualty or taking is waived by Purchaser, to exclude the affected Property from the Assets and reduce the Purchase Price by the Allocated Value thereof; provided, however, that any adjustment to the Purchase Price pursuant to this Section 3.6 may not be used in meeting the Defect Deductible. In each case, Seller shall retain all rights to insurance and other claims against third parties with respect to the casualty or taking except to the extent the parties otherwise agree in writing.

Section 3.7    Limitations on Applicability.

The rights of Purchaser under Section 3.1(a) and Section 3.4(a) shall terminate as of the Title Claim Date and be of no further force and effect thereafter, provided there shall be no termination of Purchaser’s or Seller’s rights under Section 3.4 with respect to any bona fide Title Defect properly reported in a Title Defect Notice or bona fide Title Benefit properly reported in a Title Benefit Notice on or before the Title Claim Date. Except as provided in this Article 3 and for the Special Warranty in the Conveyance (subject to Section 7.9), Purchaser releases, remises and forever discharges the Seller Indemnitees from any and all suits, legal or administrative proceedings, claims, demands, damages, losses, costs, liabilities, interest or causes of action whatsoever, in Law or in equity, known or unknown, which Purchaser might now or subsequently may have, based on, relating to or arising out of, any Title Defect or other deficiency in or encumbrance on title to any Asset.

Section 4.1    Assessment.

Subject to the limitations set forth herein and in Section 7.1, Purchaser may, at its option, cause, or cause to be conducted by a reputable environmental consulting or engineering firm approved in advance in writing by Seller, which approval will not be unreasonably withheld, conditioned or delayed (the “Environmental Consultant”) an environmental assessment of all or any portion of the Assets and/or visual inspections, record reviews, and interviews relating to the Properties, including their condition and their compliance with Environmental Laws (the “Assessment”). The Assessment shall be conducted at the sole risk, cost and expense of Purchaser, and all of Purchaser’s and the Environmental Consultant’s activity conducted under this Section 4.1 and Section 7.1 shall be subject to the indemnity provisions of Section 7.6. Purchaser’s right of access shall not entitle Purchaser or the Environmental Consultant to operate equipment or conduct testing or sampling. Seller has the right to be present during any activities conducted on the Assets as part of the Assessment. Purchaser shall coordinate its Assessment with Seller to minimize any inconvenience to or interruption of the conduct of business by Seller. Purchaser shall abide by Seller’s, and any third party operator’s, safety rules, regulations and operating policies while conducting its due diligence evaluation of the Assets including the Assessment. Purchaser shall promptly provide, but not later than the Environmental Claim Date, copies of all reports, results, and other documentation and data prepared or compiled by Purchaser and/or any of its representatives or agents in connection with the Assessment. Seller shall not be deemed by its receipt of said documents or otherwise to have made any representation or warranty, expressed, implied or statutory, as to the condition of the Assets or the accuracy of said documents or the information contained therein. During all periods that Purchaser or any of its representatives are on the Assets, Purchaser shall maintain, at its sole expense and with reputable insurers, such insurance as is reasonably sufficient to support Purchaser’s indemnity obligations under Section 7.6.

Section 4.2    NORM.

Purchaser acknowledges the following:

(a)    The Assets have been used for exploration, development, and production of oil and gas and that there may be petroleum, produced water, wastes, or other materials located on or under the Properties or associated with the Assets.

(b)    Equipment and sites included in the Assets may contain asbestos, hazardous substances, or NORM.

(c)    NORM may affix or attach itself to the inside of wells, materials, and equipment as scale, or in other forms.

(d)    The wells, materials, and equipment located on the Properties or included in the Assets may contain NORM and other wastes or hazardous substances.

(e)    NORM containing material and other wastes or hazardous substances may have come in contact with the soil.

(f)    Special procedures may be required for the remediation, removal, transportation, or disposal of soil, wastes, asbestos, hazardous substances, and NORM from the Assets.

Section 4.3    Notice of Violations of Environmental Laws.

Purchaser shall deliver any claim notices to Seller in writing (an “Environmental Defect Notice”), on or before thirty (30) days from the date hereof (the “Environmental Claim Date”), of each individual environmental matter disclosed by the Assessment that Purchaser reasonably believes in good faith may constitute or result in (including with notice or solely with the passage of time) Environmental Liabilities for which the Lowest Cost Response to address the matter exceeds the Individual Defect Deductible, including in the Environmental Defect Notice (i) a reasonably detailed description of the specific matter that is an alleged violation of Environmental Laws, including (A) the written conclusion of Purchaser or Purchaser’s Environmental Consultant that Environmental Liabilities exist, which conclusion shall be reasonably substantiated by the factual data gathered in Purchaser’s Assessment and (B) a separate specific citation of the provisions of Environmental Laws alleged to be violated and the related facts that substantiate such violation; (ii) the Units, Wells or associated Assets affected; (iii) a detailed estimate of the Lowest Cost Response to cure or eliminate the alleged matter in question; and (iv) supporting documents reasonably necessary for Seller (as well as any consultant, inspector or expert hired by Seller) to verify the existence of the facts alleged in the Environmental Defect Notice. The failure of an Environmental Defect Notice to contain the information required by item nos. (i) through (iv) of the prior sentence on or prior to the Environmental Claim Date shall not render such notice ineffective if the defect notice is reasonably sufficient to provide notice to Seller of the existence and general nature of the alleged Environmental Defect. Purchaser shall furnish Seller, on or before the end of each calendar week prior to the Environmental Claim Date, Environmental Defect Notices with respect to any Environmental Defect that any of Purchaser’s or any of its Affiliate’s employees, representatives, attorney or other environmental personnel or contractors, including the Environmental Consultant, discover or become aware of during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Environmental Claim Date.

Section 4.4    Remedies for Violations of Environmental Laws.

If Seller confirms to its reasonable satisfaction that any individual matter described in an Environmental Defect Notice delivered pursuant to Section 4.3 may constitute or result in Environmental Liabilities for which the Lowest Cost Response to address the matter exceeds the Individual Defect Deductible, then Seller shall, at its sole election, elect to:

(a)    reduce the Purchase Price by an amount agreed upon in writing by Purchaser and Seller as being a reasonable estimate of the cost of curing the matter described in such Environmental Defect Notice;

(b)    retain the Property that is associated with such Environmental Defect Notice and affected by such matter, in which event the Purchase Price shall be reduced by an amount equal to the Allocated Value of such Property;

(c)    perform or cause to be performed prior to Closing, at the sole cost and expense of Seller, such operations as may be necessary to bring such affected Property into compliance with the applicable Environmental Law disclosed in such Environmental Defect Notice;

(d)    enter into an agreement with Purchaser whereby Seller will as soon as reasonably practicable after Closing, at the sole cost and expense of Seller, perform or cause to be performed such operations as may be necessary to bring such affected Property into compliance with the applicable Environmental Law disclosed in such Environmental Defect Notice;

(e)    indemnify Purchaser against all Damages resulting from such Environmental Defect pursuant to an indemnity agreement in a form reasonably agreeable to Seller and Purchaser which shall be assignable by Seller upon a sale or transfer of the Assets subject to such agreement to a third party; provided, that, under no circumstances shall Seller’s aggregate liability thereunder exceed the lesser of either the Allocated Value for the Asset made the subject thereof or the Lowest Cost Response for such Environmental Defect; provided further, that, in no event shall the sum of the Environmental Liabilities for all such Properties for which Seller makes an election under this Section 4.4(e) exceed five percent (5%) of the Purchase Price without Purchaser’s prior written consent; or

(f)    if applicable, terminate this Agreement pursuant to Article 10.

In the event that (i) Seller elects to proceed under Section 4.4(a) and Purchaser and Seller have failed to agree by Closing on the reduction to the Purchase Price (which agreement Seller and Purchaser shall use good faith efforts to reach) or (ii) Purchaser and Seller cannot otherwise agree on the existence, extent or amount of Environmental Liabilities alleged in an Environmental Defect Notice before Closing, Seller shall then proceed with respect to such matter under any of Sections 4.4(b), (c), (d), (e) or (f) or submit such dispute to arbitration pursuant to this Section 4.4. In the event that Seller elects to proceed under Section 4.4(d) and Purchaser and Seller have failed to agree by Closing on the terms of the agreement contemplated thereby (which agreement Seller and Purchaser shall use good faith efforts to reach), Seller shall then proceed with respect to such matter under any of Sections 4.4(b), (c), (e) or (f) or submit such dispute to arbitration pursuant to this Section 4.4.

For all matters submitted to arbitration pursuant to this Section 4.4, there shall be a single arbitrator, who shall be an environmental consultant with at least ten (10) years’ relevant experience as selected by mutual agreement of Purchaser and Seller within fifteen (15) days of an election by Seller to submit such dispute to arbitration. Absent such agreement on the selection of the arbitrator, the arbitrator shall be selected by the Dallas, Texas office of the American Arbitration Association (the “Environmental Arbitrator”). The arbitration proceeding shall be held in Dallas, Texas and shall be conducted in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Environmental Arbitrator’s determination shall be made within twenty (20) days after submission of the matters in dispute and shall be final and binding upon both parties, without right of appeal. In making his determination, the Environmental Arbitrator shall be bound by the rules set forth in this Article 4

and may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. In connection with the determination of a matter submitted to the Environmental Arbitrator Purchaser may not assert any violation of Environmental Law that is not specified by Purchaser in the applicable Environmental Claim Notice. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defect or the Lowest Cost Response for such Environmental Defect submitted by Seller and may not award damages, interest or penalties to either party hereto with respect to any matter nor may it award Purchaser a greater amount with respect to the applicable Environmental Defect than the Lowest Cost Response set forth by Purchaser in the applicable Environmental Claim Notice. Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case. Each party hereto shall bear one-half of the costs and expenses of the Environmental Arbitrator. If the validity of any Environmental Defect or the Lowest Cost Response attributable thereto, is not determined prior to Closing by the Environmental Arbitrator pursuant to this Section 4.4, all affected Properties shall be conveyed to Purchaser at Closing and the purchase price paid by Purchaser at Closing shall not be reduced by virtue of such dispute and upon final resolution of such dispute the Lowest Cost Response for such Environmental Defect as determined by the Environmental Arbitrator shall, subject to the terms of this this Section 4.4, be promptly refunded by Seller to Purchaser.

period. In the event of an emergency, Seller may take such action as a prudent operator would take and shall notify Purchaser of such action promptly thereafter.

Notwithstanding anything to the contrary in this Agreement, Seller shall have no liability to Purchaser for the incorrect payment of delay rentals, royalties, overriding royalties, shut-in payment payments or similar payments made during the Adjustment Period or for failure to make such payments through mistake or oversight (including Seller’s negligence or other fault), except that, to the extent such incorrect payment causes Seller to have less than Defensible Title to a Property prior to Closing, Purchaser may, until the Title Claim Date, assert a Title Defect under Section 3.4(a) with respect to such matter and except to the extent such incorrect payment gives rise to an adjustment to the Purchase Price, at Closing (and as a post-Closing adjustment on the statement delivered by Seller in accordance with Section 9.4(b), if applicable) but then only to the extent of such adjustment.

Notwithstanding anything to the contrary contained in this Agreement, with respect to any Asset for which Seller is not the operator, Seller shall not be deemed to have breached or otherwise violated any of its covenants or agreements contained in this Agreement that are applicable to any such Assets so long as Seller exercise reasonable commercial efforts to cause any third party operator of such Assets to comply with such covenant or agreement.

Purchaser acknowledges that Seller may own an undivided interest in certain of the Assets and Purchaser agrees that the acts or omissions of the other working interest owners who are not affiliated with Seller shall not constitute a violation of the provisions of this Article 7 nor shall any action required by a vote of working interest owners constitute such a violation so long as Seller has voted its interest in a manner consistent with the provisions of this Article 7.

Section 7.6    Indemnity Regarding Access.

Purchaser, on behalf of itself and the Purchaser Indemnitees, hereby releases and agrees to indemnify, defend and hold harmless Seller Indemnitees and the other owners of interests in the Leases and Wells described on Exhibit A or Exhibit A-1 from and against any and all claims, liabilities, losses, costs and expenses (including court costs, expert fees and reasonable attorneys’ fees), including claims, liabilities, losses, costs and expenses attributable to personal injuries, death, or property damage, arising out of or relating to access to the Assets by the Purchaser Indemnitees, the Records and other related activities or information prior to the Closing by Purchaser Indemnitees, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY INDEMNIFIED PERSON EXCLUDING, HOWEVER, ANY CLAIMS, LIABILITIES, LOSSES, COSTS OR EXPENSES CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY INDEMNIFIED PERSON.

Section 7.7    Other Preferential Rights.

Should a third party fail to exercise its preferential right to purchase as to any portion of the Assets prior to Closing and the time for exercise or waiver has not yet expired, subject to the remaining provisions of this Section 7.7, such Assets shall be included in the transaction at Closing,

such preferential right to purchase shall be a Permitted Encumbrance hereunder, and the following procedures shall be applicable. If one or more of the holders of any such preferential right to purchase notifies Seller subsequent to the Closing that it intends to assert its preferential purchase right, Seller shall give notice thereof to Purchaser, whereupon Purchaser shall satisfy all such preferential purchaser right obligations of Seller to such holders and shall indemnify and hold harmless Seller from and against any and all claims, liabilities, losses, damages, costs and expenses (including court costs, expert fees and reasonable attorney’s fees) in connection therewith, and Purchaser shall be entitled to receive (and Seller hereby assigns to Purchaser all of Seller’s rights to) all proceeds, received from such holders in connection with such preferential rights to purchase.

Prior to Closing, should any third party bring any suit, action or other proceeding seeking to restrain, enjoin or otherwise prohibit the consummation of the transactions contemplated hereby in connection with a claim to enforce preferential rights, the Assets subject to such suit, action or other proceeding shall be excluded from the Assets transferred at Closing and the Purchase Price shall be reduced by the Allocated Value of such excluded Assets. Promptly after the suit, action or other proceeding is dismissed or settled or a judgment is rendered in favor of Seller, as applicable, Seller shall sell to Purchaser, and Purchaser shall purchase from Seller, all such Assets not being sold to the third party for a purchase price equal to the Allocated Value of such Assets, adjusted as provided in Section 2.2.

Section 7.8    Tax Matters.

(a)    Subject to the provisions of Section 12.3, Seller shall be responsible for all Taxes related to the ownership or operation of the Assets that are attributable to any taxable period, or portion thereof, that ends at or prior to the Effective Time. Purchaser shall be responsible for all other Taxes related to the ownership or operation of the Assets. Regardless of which party is responsible for Taxes pursuant to the preceding sentences of this Section 7.8(a), Seller shall handle payment to the appropriate Governmental Body of all Taxes related to the ownership or operation of the Assets which are required to be paid prior to Closing (and shall file all Tax Returns with respect to such Taxes); provided that to the extent such Taxes relate to the periods from and after the Effective Time, as determined pursuant to Section 1.4(c), such payment shall be on behalf of Purchaser, and promptly following the Closing Date, following Seller’s request, Purchaser shall pay to Seller any such Taxes (but only to the extent that such amounts have not already been accounted for under Section 2.2). Purchaser shall handle payment to the appropriate Governmental Body of all Taxes related to the ownership or operation of the Assets which are required to be paid after Closing (and shall file all Tax Returns with respect to such Taxes); provided that that in the event that Seller is required by applicable Law to file a Tax Return with respect to such Taxes after the Closing Date which includes all or a portion of a Tax period for which Purchaser is liable for such Taxes, following Seller’s request, Purchaser shall promptly pay to Seller all such Taxes allocable to the period or portion thereof beginning at or after the Effective Time (but only to the extent that such amounts have not already been accounted for under Section 2.2). Notwithstanding the foregoing, this Section 7.8(a) shall not apply to income, franchise, corporate, business and occupation, business license and similar Taxes (including Taxes based on net profits, margin, revenues, gross receipts or similar measure), and Tax Returns

therefor, which shall be borne, paid and filed by the party responsible for such Taxes under applicable Law. If requested by Purchaser, Seller will assist Purchaser with preparation of all ad valorem and property Tax Returns due on or before thirty (30) days after Closing (including any extensions requested). Seller shall deliver to Purchaser within thirty (30) days of filing copies of all Tax Returns filed by Seller after the Closing Date relating to the Assets and any supporting documentation provided by Seller to Governmental Bodies.

(b)    If Seller or Purchaser (or an Affiliate of Seller or Purchaser) receives a refund of any Taxes (whether by payment, credit offset or otherwise, with any interest thereon) covered by Section 7.8(a) that are paid by and required to be borne by the other party hereto, the party that received (or whose Affiliate that received) such refund shall promptly (but no later than thirty (30) days after receipt) remit payment to such other party of an amount equal to the refund amount, with any interest thereon, including all relevant documentation. Each party hereto shall cooperate with the other and its Affiliates in order to take all reasonably necessary steps to claim any refund to which it is entitled. Purchaser agrees to notify Seller within ten (10) days following the discovery of a right to claim any refund to which Seller is entitled and upon receipt of any such refund.

(c)    Except to the extent required by applicable Laws, Purchaser shall not and shall not permit its Affiliates to amend any Tax Return with respect to Taxes for which Seller is liable under this Section 7.8 or for which Seller may be liable to indemnify Purchaser under Section 11.2. Any Tax Return prepared by Purchaser for a taxable period, or portion thereof, beginning before the Effective Time shall be prepared in accordance with Seller’s prior practice and shall not be filed without Seller’s written consent (not to be unreasonably withheld, conditioned or delayed) after providing Seller a copy thereof reasonably in advance of the due date for filing such Tax Returns. In the event that Seller is required by applicable Law to file any Tax Return with respect to Taxes for which Purchaser is responsible hereunder, Seller shall prepare and timely file such Tax Return but shall not file such Tax Return without Purchaser’s written consent (not to be unreasonably withheld, conditioned or delayed) after providing Purchaser a copy thereof reasonably in advance of the due date for filing such Tax Return. If Seller or Purchaser disputes any item on a Tax Return described in this Section 7.8(c), it shall notify the other Party of such disputed item (or items) and the basis for its objection. The Parties shall act in good faith to resolve any such dispute prior to the date on which the relevant Tax Return is required to be filed. Purchaser and Seller shall each provide the other with all information reasonably necessary to prepare any Tax Return described in this Section 7.8(c).

(d)    After the Closing, Purchaser or Seller, as applicable, shall notify the other party in writing within fifteen (15) days of the receipt of the notice of any proposed assessment or commencement of any Tax audit or administrative or judicial proceeding and of any Tax demand or claim on Purchaser or any of its Affiliates or Seller or any of its Affiliates that, if determined adversely to the taxpayer or after the lapse of time, could reasonably be grounds for indemnification by Seller or would be reasonably likely to materially increase the Tax liability of Purchaser or any of its Affiliates; provided that failure to timely provide such notice shall not affect the right of Purchaser’s indemnification

hereunder, except to the extent Seller is prejudiced by such delay or omission. Such notice shall contain factual information describing the asserted Tax liability in reasonable detail and shall include copies of any notice or other document received from any Governmental Body in respect of any such asserted Tax liability. Seller shall control any proceeding with respect to any Taxes or Tax Returns relating to or with respect to any Asset (“Tax Audit”) for any item relating to a Tax for which Seller is reasonably likely to be responsible, in whole or in part, pursuant to Section 7.8(a) or for which Seller may be liable to indemnify Purchaser under Section 11.2. Neither Purchaser nor Seller shall settle any such Tax Audit in a way that would adversely affect the other party without the other party’s written consent, which consent the other party shall not unreasonably withhold, delay or condition. Purchaser and Seller shall each provide the other with all information reasonably necessary to conduct a Tax Audit with respect to Taxes or the transactions contemplated by this Agreement.

(e)    If, prior to Closing, Seller has paid on behalf of other working interest owners, royalty interest owners, overriding royalty interest owners and other interest owners in the Assets, ad valorem, property, severance, production and similar Taxes imposed on the ownership of the Assets or the production of Hydrocarbons produced from such Assets for Tax periods or portions thereof after the Effective Time (such amounts, “Post-Effective Time Tax Advances”) and has not recouped such Post-Effective Time Tax Advances before the Closing Date from such working interest owners, royalty interest owners, overriding royalty interest owners and other interest owners in the Assets, Purchaser shall use its commercially reasonable efforts to recoup the Post-Effective Time Tax Advances from such other working interest owners, royalty interest owners, overriding royalty interest owners and other interest owners in such Assets and shall promptly remit any such recovered Post-Effective Time Tax Advance amounts to Seller.

(f)    Notwithstanding Section 12.11, Purchaser and Seller hereby agree that any party, at its sole expense, may elect a like-kind exchange under Section 1031 of the Code with respect to the transactions contemplated by this Agreement.  Seller, at its expense, shall have the right at any time prior to the Closing to assign all or a portion of its rights under this Agreement to a “qualified intermediary” (as that term is defined in Treasury Regulations Section 1.1031(k)-1(g)(4)(iii)) or an “exchange accommodation titleholder” (as that term is defined in Revenue Procedure 2000-37, 2000-2 C.B. 308) in order to effectuate the transactions contemplated hereby at such Closing in a manner that will qualify, either in whole or in part, as a like-kind exchange under Section 1031 of the Code.  Likewise, Purchaser, at its expense, shall have the right at any time prior to the Closing to assign all or a portion of its rights under this Agreement to a qualified intermediary or an exchange accommodation titleholder for the same purpose.  In the event that any party assigns its rights under this Agreement pursuant to this Section 7.8(f), such party agrees to notify the other party in writing of such assignment on or before the Closing attributable to such rights.  Purchaser and Seller agree to cooperate to the extent reasonably requested by the other party in order to effectuate the transactions contemplated hereby as a like-kind exchange under Section 1031 of the Code; provided that (a) the Closing shall not be delayed or affected by reason of the like-kind exchange; (b) Seller shall indemnify Purchaser against any additional costs, damages or liabilities directly incurred by Purchaser on account of Seller’s

consummation of the transaction through a like-kind exchange; and (c) Purchaser shall indemnify Seller against any additional costs, damages or liabilities directly incurred by Seller on account of Purchaser’s consummation of the transaction through a like-kind exchange.  Purchaser and Seller acknowledge and agree that any assignment of rights under this Agreement to a qualified intermediary or an exchange accommodation titleholder shall not release any party from, or modify, any of its obligations to the other party under this Agreement and that no party represents to any other party that any particular Tax treatment will be given to any party as a result thereof.  In no event will any party be liable to any other party for any failure of any transaction to qualify for like-kind treatment under Section 1031 of the Code. 

Section 7.9    Special Warranty of Title.

The Conveyance shall contain a covenant of Seller to warrant Defensible Title to the Leases, Wells and Units after Closing from and against the lawful claims of third parties arising by, through or under Seller, but not otherwise, that are not reflected or referred to of record in the counties where the lands covered by the Leases and Units are located or in the materials made available to Purchaser prior to the Title Claim Date (the “Special Warranty”); provided, however, that, notwithstanding anything herein to the contrary, (i) Seller shall not be liable to Purchaser Indemnitees for any Damages resulting from a breach of such covenant unless (A) the sum of (x) Damages resulting from such breach plus (y) Title Defect Amounts for Title Defects covered by Section 3.4(d)(i) plus (z) Environmental Liabilities covered by Section 4.4(a), exceeds the Defect Deductible, after which point Seller shall be liable for such Damages in excess of the Defect Deductible and (B) Purchaser delivers notice to Seller of such claim on or before the date that is the third anniversary of the Closing Date and (ii) without limiting clause (i), Seller’s liability to Purchaser in respect of such covenant for any Lease, Well or Unit shall not exceed the Allocated Value of the Lease, Well or Unit. Without limiting the foregoing, Purchaser shall not be entitled to claim a breach of the Special Warranty for any Title Defect claimed in a Title Defect Notice or of which Purchaser had knowledge on or before the Title Claim Date.

Section 7.10    Suspended Proceeds.

Seller shall transfer and remit to Purchaser, in the form of an adjustment to the Purchase Price, at Closing (and as a post-Closing adjustment on the statement delivered by Seller in accordance with Section 9.4(b), if applicable), all monies representing the value or proceeds of production removed or sold from the Properties and held by Seller at the time of the Closing for accounts from which payment has been suspended, such monies, net of applicable rights of set off or recoupment, being hereinafter called “Suspended Proceeds”. Purchaser shall be solely responsible for the proper distribution of such Suspended Proceeds to the Person or Persons which or who are entitled to receive payment of the same.

Section 7.11    Further Assurances.

After Closing, Seller and Purchaser each agrees to take such further actions and to execute, acknowledge and deliver all such further documents as are reasonably requested by the other party

hereto for carrying out the purposes of this Agreement or of any document delivered pursuant to this Agreement.

The estimate delivered in accordance with this Section 9.4(a) shall constitute the dollar amount to be paid by Purchaser to Seller at the Closing (the “Closing Payment”).

(b)    As soon as reasonably practicable after the Closing but not later than one hundred twenty (120) days following the Closing Date, Seller shall prepare and deliver to Purchaser a statement setting forth the final calculation of the Adjusted Purchase Price and showing the calculation of each adjustment, based, to the extent possible on actual credits, charges, receipts and other items before and after the Effective Time and taking into account all adjustments provided for in this Agreement.

If the parties hereto are unable to agree upon an Independent Expert, then such Independent Expert shall be selected by any Federal District Court Judge or State District Court Judge in Dallas, Texas.

The Independent Expert shall conduct the arbitration proceedings in Dallas, Texas in accordance with the Commercial Arbitration Rules of the American Arbitration Association, to the extent such rules do not conflict with the terms of this Section. The Independent Expert’s determination shall be made within thirty (30) days after submission of the matters in dispute and shall be final and binding on both parties hereto, without right of appeal. In determining the proper amount of any adjustment to the Purchase Price, the Independent Expert shall not increase the Purchase Price more than the increase proposed by Seller nor decrease the Purchase Price more than the decrease proposed by Purchaser, as applicable. The Independent Expert shall act as an expert for the limited purpose of determining the specific disputed matters submitted by either party hereto and may not award damages or penalties to either party hereto with respect to any matter. Seller and Purchaser shall each bear its own legal fees and other costs of presenting its case. Each party hereto shall bear one-half of the costs and expenses of the Independent Expert. Within ten (10) days after the date on which the parties hereto or the Independent Expert, as applicable, finally determines the disputed matters, (i) Purchaser shall pay to Seller the amount by which the Adjusted Purchase Price exceeds the Closing Payment or (ii) Seller shall pay to Purchaser the amount by which the Closing Payment exceeds the Adjusted Purchase Price, as applicable. Any post-closing payment pursuant to this Section 9.4 shall bear interest from the Closing Date to the date of payment at the Agreed Interest Rate.

(c)    All payments made or to be made hereunder to Seller shall be by electronic transfer of immediately available funds to the account of Seller pursuant to the wiring instructions reflected in Schedule 9.4(c).

Section 10.1    Termination.

Subject to Section 10.2, this Agreement shall be terminated: (i) at any time prior to Closing by the mutual prior written consent of Seller and Purchaser; (ii) by Seller or Purchaser if Closing has not occurred on or before the date that is sixty (60) days from the date hereof (or in the event such date is not a Business Day then the next Business Day immediately following such date) (the “Termination Date”); (iii) by Purchaser if any condition set forth in Section 8.2 has not been satisfied or waived at Closing or (iv) by Seller if any condition set forth in Section 8.1 has not been satisfied or waived at Closing; provided, however, that termination under clauses (ii), (iii) or (iv) shall not be effective until the party electing to terminate has delivered written notice to the other

party of its election to so terminate and provided, however, that no Party shall have the right to terminate this Agreement pursuant to clauses (ii), (iii) or (iv) above, if such Party or its Affiliates are at such time in material breach of any provision of this Agreement.

Section 10.2    Effect of Termination.

If this Agreement is terminated pursuant to Section 10.1, except as set forth in this Section 10.2 and in Section 10.3, this Agreement shall become void and of no further force or effect (except for the provisions of Sections 5.6, 6.5, 7.6, 11.6, 12.2, 12.4, 12.7, 12.8, 12.9, 12.10 12.11, 12.12, 12.13, 12.14, 12.15, 12.16, 12.17, 12.18, and 12.19 and of the Confidentiality Agreement which shall continue in full force and effect) and Seller shall be free immediately to enjoy all rights of ownership of the Assets and to sell, transfer, encumber or otherwise dispose of the Assets to any Person without any restriction under this Agreement. Subject to Section 10.3, the termination of this Agreement under Section 10.1(ii), (iii) or (iv) shall not relieve any party hereto from liability to the other party at Law or in equity for any failure to perform or observe in any material respect any of its agreements or covenants contained herein which are to be performed or observed at or prior to Closing.

Section 10.3    Distribution of Deposit Upon Termination.

(a)    If this Agreement is terminated by Seller pursuant to Section 10.1(ii) or Section 10.1(iv) and Seller has performed or is ready, willing and able to perform all of its agreements and covenants contained herein which are to be performed or observed at or prior to Closing, then Seller shall retain the Deposit as liquidated damages as Seller’s sole and exclusive remedy for any breach or failure to perform by Purchaser under this Agreement, and all other remedies (except those under Section 7.6 and the Confidentiality Agreement, which shall remain in full force and effect) are hereby expressly waived by Seller. In the event that prior to such termination Purchaser has engaged in any hedging transactions related to the transactions contemplated by this Agreement and entered into on or around the date hereof (including any swaps, puts or similar hedging agreements), then to the extent that at the time of such termination set forth in the first sentence above, such hedging transactions either represent a positive gain in favor of Purchaser or its Affiliate or give rise to an obligation of the other party to such hedging agreement to make a payment to Purchaser or its Affiliate, Purchaser shall pay to Seller, in immediately available funds, an amount equal to the greater of such positive gain or payment (which amount shall be in addition to the Deposit). Notwithstanding anything contained in this Agreement to the contrary, the retention of the Deposit and other remedies provided in this Section 10.3(a) shall be the sole and exclusive remedy of Seller for Purchaser’s breach of this Agreement or failure or refusal to close, and Seller expressly waives any and all other remedies, legal and equitable, that it otherwise may have had for Purchaser’s breach of this Agreement or failure or refusal to close. Seller and Purchaser agree that the retention of the Deposit constitutes liquidated damages due to the difficulty and inconvenience of measuring actual damages and the uncertainty thereof, and Seller and Purchaser agree that such amount would be a reasonable estimate of Seller’s loss in the event of any such breach or failure to perform by Purchaser. Upon such termination, Seller shall be free immediately to enjoy all rights

of ownership of the Assets and to sell, transfer, encumber or otherwise dispose of the Assets to any Person without any restriction under this Agreement.

(b)    If this Agreement is terminated by Purchaser pursuant to Sections 10.1(ii) or 10.1(iii) and Purchaser has performed or is ready, willing and able to perform all of its agreements and covenants contained herein which are to be performed or observed at or prior to Closing, then at Purchaser’s option:

(i)    Seller shall return the Deposit to Purchaser and Purchaser shall be entitled to seek money damages from Seller available at Law for Seller’s applicable breach of this Agreement, as Purchaser’s sole and exclusive remedy for any breach or failure to perform by Seller under this Agreement, and all other remedies (except those under the Confidentiality Agreement, which shall remain in full force and effect) are hereby expressly waived by Purchaser, and Seller shall be free immediately to enjoy all rights of ownership of the Assets and to sell, transfer, encumber or otherwise dispose of the Assets to any Person without any restriction under this Agreement; or

(ii)    in lieu of termination of this Agreement, Purchaser shall be entitled to specific performance of this Agreement, it being specifically agreed that monetary damages will not be sufficient to compensate Purchaser if Purchaser determines the same in its sole discretion. If Purchaser elects to seek specific performance of this Agreement pursuant to this Section 10.3(b)(ii), the Deposit shall be held by Seller, until a non-appealable final judgment or award on Purchaser’s claim for specific performance is rendered, at which time the Deposit shall be distributed as provided in the judgment or award resolving the specific performance claim or shall be applied as provided in Section 2.4 of this Agreement.

(c)    If this Agreement terminates for reasons other than those set forth in Section 10.3(a) or Section 10.3(b), Seller shall deliver the Deposit to Purchaser, free of any claims by Seller or any other Person with respect thereto, and each party hereto shall have no further liability hereunder of any nature whatsoever to the other party hereto, including any liability for Damages (except for the provisions of Sections 5.6, 6.5, 7.6 and 12.4 and the Confidentiality Agreement which shall continue in full force and effect in accordance with their terms), and Seller shall be free immediately to enjoy all rights of ownership of the Assets and to sell, transfer, encumber or otherwise dispose of the Assets to any Person without any restriction under this Agreement.

(d)    Notwithstanding anything to the contrary in this Agreement, Purchaser shall not be entitled to receive interest on the Deposit, regardless of whether the Deposit is applied against the Purchase Price or returned to Purchaser pursuant to this Section 10.3.

Section 11.1    Receipts.

(a)    Except as otherwise provided in this Agreement, any production from or attributable to the Assets (and all products and proceeds attributable thereto) and any other income, proceeds, receipts and credits attributable to the Assets which are not reflected in the adjustments to the Purchase Price following the final adjustment pursuant to Section 9.4(b) shall be treated as follows: (i) all production from or attributable to the Assets (and all products and proceeds attributable thereto) and all other income, proceeds, receipts and credits earned with respect to the Assets to which Purchaser is entitled under Section 1.4 shall be the sole property and entitlement of Purchaser, and, to the extent received by Seller, Seller shall fully disclose, account for and remit the same to Purchaser within ten (10) days, and (ii) all production from or attributable to the Assets (and all products and proceeds attributable thereto) and all other income, proceeds, receipts and credits earned with respect to the Assets to which Seller is entitled under Section 1.4 shall be the sole property and entitlement of Seller and, to the extent received by Purchaser, Purchaser shall fully disclose, account for and remit the same to Seller within ten (10) days.

(b)    Notwithstanding any other provisions of this Agreement to the contrary, Seller shall be entitled to retain (and Purchaser shall not be entitled to any decrease to the Purchase Price in respect of) all overhead charges it has collected, billed or which shall be billed later to or from non-Affiliated third parties, relating to the Seller Operated Assets and relating to the period from the Effective Time to the Closing Date.

Section 11.2    Assumption and Indemnification.

(a)    Without limiting Purchaser’s rights to indemnity under this Article 11, on the Closing Date, Purchaser shall assume and hereby agrees to timely fulfill, perform, pay and discharge (or cause to be fulfilled, performed, paid or discharged) all of the obligations and liabilities of Seller, known or unknown, with respect to the Assets, regardless of whether such obligations or liabilities arose prior to, on or after the Effective Time, including but not limited to (1) obligations to furnish makeup gas according to the terms of applicable gas sales, gathering or transportation contracts, (2) gas balancing obligations and other obligations arising from Imbalances, (3) obligations to pay Property Costs, (4) obligations to pay working interests, royalties, overriding royalties and other interests held in suspense, including the Suspended Proceeds, (5) obligations to plug or abandon wells and associated equipment and dismantle structures, and to restore and/or remediate the Assets in accordance with applicable agreements, Leases or Laws (including Environmental Laws), (6) any claims regarding the general method, manner or practice of calculating or making royalty payments (or payments for overriding royalties or similar burdens on production) with respect to the Properties and (7) continuing obligations, if any, under any Contracts or other agreements pursuant to which Seller or its Affiliates purchased or acquired Assets prior to the Closing (all of said obligations and liabilities, subject to the exclusions below, herein being referred to as the “Assumed Obligations”); provided, however, that the Assumed Obligations do not include and Purchaser does not assume any obligations or liabilities of Seller to the extent that they are Seller Indemnity Obligations.

(b)    Except for Damages for which Seller is required to indemnify Purchaser Indemnitees under Section 11.2(c) at the time an applicable Claim Notice is provided to Seller, Purchaser shall indemnify, defend and hold harmless Seller Indemnitees from and against all Damages incurred or suffered by Seller Indemnitees to the extent:

(i)    caused by, arising out of, resulting from or relating to the Assumed Obligations;

(ii)    caused by, arising out of or resulting from Purchaser’s breach of any of Purchaser’s covenants or agreements that survive the Closing;

(iii)    caused by, arising out of or resulting from any breach of any representation or warranty made by Purchaser contained in Article 6 of this Agreement or in the certificate delivered by Purchaser at Closing pursuant to Section 9.3(f), provided, however, that solely for purposes of this Section 11.2(b), any representation or warranty of Purchaser set forth in this Agreement that is qualified by “materiality” or “Material Adverse Effect” shall be deemed not to be so qualified; or

(iv)    caused by, arising out of or resulting from any claims or actions asserted by Persons (including Governmental Bodies) with respect to (1) any condition affecting any Asset that violates or requires remediation under Environmental Law, (2) any operations conducted on such Asset that violate any Environmental Law or (3) any remediation required for an Asset under any Environmental Law regardless of whether known or unknown, or whether attributable to periods of time before, on or after the Effective Time.

EVEN IF SUCH DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF SELLER INDEMNITEES OR ANY INDEMNIFIED PERSON EXCLUDING, HOWEVER, ANY DAMAGES CAUSED BY THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF ANY INDEMNIFIED PERSON.

(c)    Seller shall jointly and severally indemnify, defend and hold harmless Purchaser Indemnitees against and from all Damages incurred or suffered by Purchaser Indemnitees to the extent (the “Seller Indemnity Obligations”):

(i)    caused by, arising out of or resulting from any breach asserted during the applicable survival period of any of Seller’s covenants or agreements that survive the Closing;

(ii)    caused by, arising out of or resulting from any breach asserted during the applicable survival period of any representation or warranty made by Seller contained in Article 5 of this Agreement or in the certificate delivered by Seller at Closing pursuant to Section 9.2(d); provided, however, that solely for purposes of

this Section 11.2(c), any representation or warranty of Seller set forth in this Agreement that is qualified by “materiality” or “Material Adverse Effect” shall be deemed not to be so qualified;

(iii)    directly caused by or arising out of any matter listed on Schedule 5.7;

(iv)    caused by, arising out of, resulting from or related to the Excluded Assets;

(v)    attributable to any obligations to Seller’s employees (related to their employment with Seller), Affiliates (except operating expenses) and officers, in each case attributable to the period from and after the Effective Time, incurred in the ordinary course of business and consistent with past practice;

(vi)    any obligations under employment contracts or retention, severance, termination, separation or incentive compensation with respect to Seller’s employees, Affiliates or officers;

(vii)    attributable to any personal injury or death relating to Seller’s ownership, use or operation of the Assets that occurs prior to the Closing Date to the extent a claim is asserted prior to the second anniversary of the Closing Date; or

(viii)    attributable to liabilities and obligations for royalties, taxes and Imbalances that are attributable to or arise out of Seller’s ownership, use or operation of the Assets prior to the Effective Time to the extent a claim is asserted during the period of one hundred eighty (180) days counted from and after the Closing Date (including such one hundred eightieth (180th) day).

(d)    Notwithstanding anything to the contrary contained in this Agreement, except for the rights of the parties hereto under Article 10, Section 7.6 and the Special Warranty in the Conveyance (subject to Section 7.9), this Section 11.2 contains the parties’ exclusive remedy against each other with respect to breaches of this Agreement, including breaches of the representations and warranties contained in Articles 5 and 6, the covenants and agreements that survive the Closing pursuant to the terms of this Agreement and the affirmations of such representations, warranties, covenants and agreements contained in the certificate delivered by each party at Closing pursuant to Sections 9.2(d) or 9.3(f), as applicable. Except for the remedies contained in this Section 11.2 and for the rights of the parties hereto under Article 10, Section 7.6 and the Special Warranty in the Conveyance (subject to Section 7.9), Purchaser (on behalf of itself, each of the other Purchaser Indemnitees and their respective insurers and successors in interest) releases, remises and forever discharges the Seller Indemnitees from any and all suits, legal or administrative proceedings, claims, remedies, demands, damages, losses, costs, liabilities, interest, or causes of action whatsoever, in Law or in equity, known or unknown, which such parties might now or subsequently may have, based on, relating to or arising out of this Agreement, Seller’s or Seller’s predecessor’s or their respective co-owner’s ownership, use or operation of the Assets, or the condition, quality, status or nature of the Assets, including rights to

contribution under the CERCLA, as amended, and under other Environmental Laws, breaches of statutory or implied warranties, nuisance or other tort actions, rights to punitive damages and common law rights of contribution, rights under agreements between Seller and any Persons who are Affiliates of Seller, and rights under insurance maintained by Seller or any Person who is an Affiliate of Seller, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT OR CONCURRENT, BUT EXCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT), OF ANY RELEASED PERSON, excluding, however, any existing contractual rights between (i) Purchaser or any of Purchaser’s Affiliates and (ii) Seller or any of Seller’s Affiliates under contracts between them relating to the Assets, other than this Agreement.

(e)    “Damages”, for purposes of this Agreement, shall mean the amount of any actual liability, loss, cost, diminution in value, expense, claim, demand, notice of violation, investigation by any Governmental Body, administrative proceeding, payment, charge, obligation, fine, penalty, deficiency, award or judgment incurred or suffered by any Indemnified Party arising out of or resulting from the indemnified matter, including reasonable fees and expenses of attorneys, consultants, accountants or other agents and experts reasonably incident to matters indemnified against, and the costs of investigation and/or monitoring of such matters, and the costs of enforcement of the indemnity; provided, however, that no Purchaser Indemnitee shall be entitled to indemnification under this Section 11.2 for Damages that constitute (i) loss of profits or other consequential or indirect damages suffered by Purchaser, or any punitive damages, or (ii) any liability, loss, cost, expense, claim, award or judgment to the extent resulting from or increased by the actions or omissions of any Purchaser Indemnitee after the Effective Time.

(f)    Any claim for indemnity to which a Seller Indemnitee or Purchaser Indemnitee is entitled must be asserted by and through Seller or Purchaser, as applicable.

Section 11.3    Indemnification Actions.

Except as otherwise provided in Section 7.8(d), all claims for indemnification under Section 11.2 shall be asserted and resolved as follows:

(a)    For purposes of this Article 11, the term “Indemnifying Party” when used in connection with particular Damages shall mean the party or parties hereto having an obligation to indemnify another party or parties with respect to such Damages pursuant to this Article 11, and the term “Indemnified Party” when used in connection with particular Damages shall mean the Person or Persons having the right to be indemnified with respect to such Damages by another party or parties pursuant to this Article 11.

(b)    To make a claim for indemnification under Article 11, an Indemnified Party shall notify the Indemnifying Party of its claim under this Section 11.3, including the specific details of and specific basis under this Agreement for its claim (the “Claim Notice”). In the event that the claim for indemnification is based upon a claim by a third party against the Indemnified Party (a “Third Party Claim”), the Indemnified Party shall provide its Claim Notice promptly after the Indemnified Party has actual knowledge of the Third Party

Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim; provided that the failure of any Indemnified Party to give notice of a Third Party Claim as provided in this Section 11.3 shall not relieve the Indemnifying Party of its obligations under Section 11.2 except to the extent such failure prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an inaccuracy or breach of a representation, warranty, covenant or agreement, the Claim Notice shall specify the representation, warranty, covenant or agreement which was inaccurate or breached.

(c)    In the case of a claim for indemnification based upon a Third Party Claim, the Indemnifying Party shall have fourteen (14) days from its receipt of the Claim Notice to notify the Indemnified Party whether it admits or denies its liability to defend the Indemnified Party against such Third Party Claim at the sole cost and expense of the Indemnifying Party. The Indemnified Party is authorized, prior to and during such fourteen (14)-day 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 that is not prejudicial to the Indemnifying Party all costs of which shall be included as Damages in respect of such claim for indemnification. The failure to provide notice to the Indemnified Party shall be deemed to be acceptance of liability.

(d)    If the Indemnifying Party admits its liability, it shall have the right and obligation to diligently defend, at its sole cost and expense, the Third Party Claim. The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate, at the sole cost of the Indemnifying Party, in contesting any Third Party Claim which the Indemnifying Party elects to contest. The Indemnified Party may participate in, but not control, at its sole cost without any right of reimbursement, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 11.3(d). Irrespective of whether the Indemnified Party elects to participate in contesting a Third Party Claim subject to this Section 11.3(d) in accordance with the foregoing sentence, the Indemnifying Party at its sole cost and expense shall provide to the Indemnified Party the following information with respect to the Third Party Claim: all filings made by any party; all written communications exchanged between any parties; and all orders, opinions, rulings or motions. The Indemnifying Party shall deliver the foregoing items to the Indemnified Party promptly after they become available to the Indemnifying Party. An Indemnifying Party shall not, without the written consent of the Indemnified Party (which shall not be unreasonably withheld, conditioned or delayed), (i) settle any Third Party Claim or consent to the entry of any judgment with respect thereto which does not include an unconditional written release of the Indemnified Party from all liability in respect of such Third Party Claim or (ii) settle any Third Party Claim or consent to the entry of any judgment with respect thereto in any manner that may materially and adversely affect the Indemnified Party (other than as a result of money damages paid by the Indemnifying Party or covered fully by the indemnity).

(e)    If the Indemnifying Party does not admit its liability or admits its liability but fails to diligently prosecute or settle the Third Party Claim, then the Indemnified Party shall have the right to defend against the Third Party Claim at the sole cost and expense of the Indemnifying Party, with counsel of the Indemnified Party’s choosing, subject to the right of the Indemnifying Party to admit its liability and assume the defense of the Third Party Claim at any time prior to settlement or final determination thereof. If the Indemnifying Party has not yet admitted its liability for a Third Party Claim, the Indemnified Party shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i) admit in writing its liability for the Third Party Claim and (ii) if liability is so admitted, reject, in its reasonable judgment, the proposed settlement. If Indemnifying Party fails to respond and admit in writing its liability during such ten (10) day period, the Indemnifying Party will be deemed to have approved such proposed settlement.

(f)    In the case of a claim for indemnification not based upon a Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice to (i) cure or remedy the Damages complained of, (ii) admit its liability for such Damages or (iii) dispute the claim for such Damages. If the Indemnifying Party does not notify the Indemnified Party within such 30-day period that it has cured or remedied the Damages or that it disputes the claim for such Damages, the Indemnifying Party shall be deemed to have disputed the claim for such Damages.

Section 11.4    Limitation on Actions.

(a)    All representations and warranties of Seller and Purchaser contained herein shall survive until the date that is one hundred eighty (180) days counted from and after the Closing Date (including such one hundred eightieth (180th) day) and expire thereafter, except for the representations and warranties set forth in Sections 5.2, 5.3, 5.4, 5.6 and 5.8 which shall survive the Closing indefinitely. The covenants and other agreements of Seller and Purchaser set forth in this Agreement to be performed on or before Closing shall expire on the day following the Closing Date and each other covenant and agreement of Seller and Purchaser shall, subject to this Section 11.4, survive the Closing until fully performed in accordance with its terms and expire thereafter. The affirmations of representations, warranties, covenants and agreements contained in the certificate delivered by each party hereto at Closing pursuant to Sections 9.2(g) and 9.3(f), as applicable, shall survive the Closing as to each representation, warranty covenant and agreement so affirmed for the same period of time that the specific representation, warranty, covenant or agreement survives the Closing pursuant to this Section 11.4, and shall expire thereafter. Representations, warranties, covenants and agreements shall terminate and be of no further force and effect after the respective date of their expiration, after which time no claim may be asserted thereunder by any Person, provided that there shall be no termination of any bona fide claim asserted pursuant to Section 11.4(c).

(b)    The indemnities in Sections 11.2(b)(ii), 11.2(b)(iii), 11.2(c)(i) and 11.2(c)(ii) shall terminate as of the termination date of each respective representation, warranty,

covenant or agreement that is subject to indemnification, except in each case as to matters for which a specific written claim for indemnity has been delivered to the Indemnifying Party on or before such termination date. Purchaser’s indemnities in Sections 7.6, 11.2(b)(i), and 11.2(b)(iv) shall continue without time limit. The indemnities in Section 11.2(c) shall terminate as set forth therein or on the dates set forth below, to the extent applicable.

(c)    Notwithstanding anything to the contrary contained elsewhere in this Agreement, except for claims for breaches of the Special Warranty and any payments in respect thereof:

(i)    Seller shall not be required to indemnify any Person under Section 11.2(c)(ii) for any individual liability, loss, cost, expense, claim, award or judgment that does not exceed Seventy-five Thousand Dollars ($75,000), except for Damages directly arising from claims for breaches of Sections 5.2, 5.3, 5.4, 5.6 or 5.8;

(ii)    Subject to Section 11.4(c)(i), Seller shall not have any liability for indemnification under Section 11.2(c)(ii) (except for Damages directly arising from claims for breaches of Sections 5.2, 5.3, 5.4, 5.6 or 5.8) until and unless the aggregate amount of the liability for all Damages for which Claim Notices are timely delivered by Purchaser exceeds a deductible amount equal to two percent (2%) of the Purchase Price (the “Indemnity Deductible”), after which point Purchaser (or Purchaser Indemnitees) shall be entitled to claim Damages in excess of the Indemnity Deductible; and

(iii)    Seller shall not be required to indemnify Purchaser and Purchaser Indemnitees for aggregate Damages under Section 11.2(c)(ii) in excess of fifteen percent (15%) of the Purchase Price, except for Damages directly arising from claims for breaches of Sections 5.2, 5.3, 5.4, 5.6 or 5.8.

(iv)    Seller shall not be required to indemnify any Person under Section 11.2(c)(ii) unless Seller has received a Claim Notice with respect to such claim at or prior to the date that is one hundred eighty (180) days counted from and after the Closing Date (including such one hundred eightieth (180th) day), except for Claim Notices delivered after such time period relating to claims for breaches of Sections 5.2, 5.3, 5.4, 5.6 or 5.8 but only to the extent relating to breaches of such Sections.

(d)    Seller and Purchaser acknowledge that after the Closing the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant or agreement contained in this Agreement or for any other claim arising in connection with or with respect to the transactions contemplated in this Agreement. As the payment of money shall be adequate compensation, Purchaser and Seller waive any right to rescind this Agreement or any of the transactions contemplated hereby.

(e)    Notwithstanding anything to the contrary stated in this Agreement, Purchaser’s obligation to indemnify Seller Indemnitees with respect to the Assumed

Liabilities shall not extend to any amount actually received by Seller from an indemnification from a non-Affiliated third party. The amount of any Damages for which an Indemnified Person is entitled to indemnity under this Agreement shall be reduced by the amount of insurance proceeds realized by the Indemnified Party or its Affiliates with respect to such Damages. From and until the second anniversary of the Closing Date, Seller shall use commercially reasonable efforts to notify its insurers of any potential claim for which Purchaser (pursuant to the terms of this Agreement) may be required to indemnify Seller and with respect to which Seller reasonably believes is covered by its insurance with such insurer; provided, however, that Seller shall have no obligations to take any action with its insurers beyond such notification and notwithstanding anything to the contrary contained herein, should Seller for any reason fail to deliver such notice to its insurers, such failure shall have no impact on Purchaser’s obligation to indemnify Seller which shall in no way be conditioned upon Seller’s delivery or failed delivery of such notice.

Section 11.5    Recording.

As soon as practicable after Closing, Purchaser shall record the Conveyances in the appropriate counties or parishes as well as the appropriate governmental agencies and provide Seller with copies of all recorded or approved instruments.

Section 11.6    Waivers.

(a)    It is the intention of the parties hereto that Purchaser’s rights and remedies with respect to this transaction and with respect to all acts or practices of Seller, past, present or future, in connection with this transaction shall be governed by legal principles other than the Texas Deceptive Trade Practices-Consumer Protection Act, Subchapter E of Chapter 17, Sections 17.41 et seq., of the Texas Business and Commerce Code, as amended (the “DTPA”) or the Louisiana unfair trade practices and consumer protection law, La.R.S. 51:1401, et seq. (the “UTPCPL”). As such, Purchaser hereby waives the applicability of the DTPA and the UTPCPL to this transaction and any and all duties, rights or remedies that might be imposed by the DTPA or the UTPCPL, whether such duties, rights and remedies are applied directly by the DTPA or the UTPCPL themselves or indirectly in connection with other statutes. Purchaser acknowledges, represents and warrants that it is purchasing the goods and/or services covered by this Agreement for commercial or business use; that it has assets of Five Million and No/100 Dollars ($5,000,000.00) or more according to its most recent financial statement prepared in accordance with GAAP; that it has knowledge and experience in financial and business matters that enable it to evaluate the merits and risks of a transaction such as this; and that it is not in a significantly disparate bargaining position with Seller.

(b)    Purchaser expressly recognizes that the price for which Seller has agreed to perform its obligations under this Agreement has been predicated upon the inapplicability of the DTPA and the UTPCPL and this waiver of the DTPA and the UTPCPL. Purchaser further recognizes that Seller, in determining to proceed with the entering into of this Agreement, has expressly relied on this waiver and the inapplicability of the DTPA and the UTPCPL.

(c)    Purchaser waives all rights in redhibition pursuant to Louisiana Civil Code 2475 and 2520 through 2548, and acknowledges that this express waiver shall be considered a material and integral part of this sale and the consideration thereof. Purchaser acknowledges that this waiver has been brought to its attention and has been explained in detail and that Purchaser has voluntarily and knowingly consented to this waiver of warranty of fitness and warranty against redhibitory vices and defects for the Assets.

(d)    To the extent applicable to the Assets or any portion thereof, Purchaser hereby waives the provisions of the UTPCPL. Purchaser warrants and represents that it: (i) is experienced and knowledgeable with respect to the oil and gas industry generally and with transactions of this type specifically; (ii) possesses ample knowledge, experience and expertise to evaluate independently the merits and risks of the transactions herein contemplated; and (iii) is not in a significantly disparate bargaining position.

(e)    The parties hereto do not intend that any implied obligation of good faith or fair dealing requires any party hereto to incur, suffer or perform any act, condition or obligation contrary to the terms of this Agreement or any documents delivered in connection herewith and that it would be unfair, and that they do not intend, to increase any of the obligations of any party under this Agreement or any documents delivered in connection herewith on the basis of any such implied obligation.

(f)    Purchaser acknowledges that plugging, abandonment, removal and restoration obligations for the Assets are material and significant. Purchaser acknowledges that Purchaser has conducted its own investigation and evaluation as to the cost and timing of such obligations and that, other than the representations and warranties set forth in this Agreement, Seller has made no representation or warranty as to the expected cost or timetable for incurring costs of plugging, abandonment, removal and restoration obligations for the Assets. Purchaser acknowledges that Seller is entering into this Agreement in reliance upon Purchaser's agreement to assume such obligations and all other Assumed Obligations and that assumption of the Assumed Obligations constitutes material agreed consideration to Seller in consideration for the Assets.

Section 11.7    Tax Treatment of Indemnification Payments.

The parties hereto agree that any payments made by one party to the other party pursuant to this Article 11 shall be treated for all Tax purposes as an adjustment to the purchase price for the Assets unless otherwise required by applicable Law.

Section 12.1    Counterparts.

This Agreement may be executed in counterparts, each of which shall be deemed an original instrument, but all such counterparts together shall constitute but one agreement. Delivery of an

executed counterpart signature page by facsimile or electronic transmittal (PDF) is as effective as executing and delivering this Agreement in the presence of other parties to this Agreement.

Section 12.2    Notice.

All notices which are required or may be given pursuant to this Agreement shall be sufficient in all respects if given in writing and delivered personally, by facsimile or by registered or certified mail, postage prepaid, as follows:

Notwithstanding the foregoing, delivery by Seller or Purchaser (as applicable) of a Title Defect Notice, Title Benefit Notice or statement of the Purchase Price under Section 9.4 shall be deemed to have been duly given to the other party when (i) transmitted via electronic mail to the address(es) of the representative(s) of such party named above that were previously furnished to the delivering party and (ii) the delivering party has provided notice to the other party of such electronic mail pursuant to the previous sentence.

Section 12.3    Sales or Use Tax, Recording Fees, and Similar Taxes and Fees.

Purchaser shall bear any sales, use, excise, real property transfer, gross receipts, goods and services, registration, capital, documentary, stamp or transfer Taxes, recording fees and similar Taxes and fees incurred and imposed upon, or with respect to, the property transfers or other transactions contemplated hereby (“Transfer Taxes”). Seller will determine, and Purchaser agrees to cooperate with Seller in determining, Transfer Taxes, if any, that applicable law requires Seller to collect from Purchaser in connection with the sale of Assets hereunder, and Purchaser agrees to pay any such tax to Seller at Closing; provided, however, that Seller’s failure to collect any such Transfer Taxes at Closing shall not absolve Purchaser from Purchaser’s responsibility for such Transfer Taxes. If such transfers or transactions are exempt from any such Taxes or fees upon the filing of an appropriate certificate or other evidence of exemption, Purchaser will timely furnish to Seller such certificate or evidence.

Section 12.4    Expenses.

Section 12.6    Replacement of Bonds, Letters of Credit and Guarantees.

The parties hereto understand that none of the bonds, letters of credit and guarantees, if any, posted by Seller with Governmental Bodies and relating to the Assets are to be transferred to Purchaser. On or before Closing, Purchaser shall obtain, or cause to be obtained in the name of Purchaser, replacements for such bonds, letters of credit and guarantees to the extent set forth on Schedule 5.19 as necessary to permit the cancellation of the bonds, letters of credit and guarantees posted by Seller or to consummate the transactions contemplated by this Agreement. Purchaser may also provide evidence that such replacements are not necessary as a result of existing bonds, letters of credit or guarantees that Purchaser has previously posted as long as such existing bonds, letters of credit or guarantees are adequate to secure the release of those posted by Seller.

Section 12.7    Governing Law and Venue.

This Agreement and the legal relations between the parties hereto shall be governed by and construed in accordance with the Laws of the State of Texas without regard to principles of conflicts

of Law that would direct the application of the Law of another jurisdiction. The venue for any action brought under this Agreement shall be Dallas County, Texas.
