If Buyer and Seller are unable to agree upon the sales prices of the assets within 30 Days after Buyer’s receipt of such notice from Seller, then any sales prices still in dispute shall be referred to the Accounting Referee. Seller and Buyer shall equally share all fees and any other charges of the Accounting Referee. The Accounting Referee shall be instructed to deliver to Seller and Buyer a written determination of the sales prices in dispute within 20 Days after the Parties’ submission of the disputed items to the Accounting Referee. Such determination shall be conclusive and binding on the Parties. Notwithstanding the foregoing, the Parties shall mutually adjust the sales prices as determined hereunder (whether or not any matter has been referred to the Accounting Referee) to the extent necessary to reflect any adjustment to the Base Purchase Price, including adjustments pursuant to Section 2.5 or as otherwise determined for U.S. federal income tax purposes. Neither Buyer nor Seller shall take, nor shall either permit any of their Affiliates to take, any position for income Tax purposes that is inconsistent with the sales prices as finally determined hereunder.

2.9 Suspended Funds. If Seller is holding any Suspended Funds as of the Closing Date, then (a) in lieu of Seller transferring these funds to Buyer at Closing, Seller shall retain the Suspended Funds held in its accounts and the Base Purchase Price shall be adjusted downward in accordance with Section 2.5(b)(iv), and (b) from and after Closing, Buyer shall be responsible for the proper payment and distribution of the Suspended Funds to the Non-Parties entitled to receive the Suspended Funds (including with respect to escheat obligations) and shall RELEASE, DEFEND, INDEMNIFY and HOLD HARMLESS Seller from and against any and all Claims asserted by Non-Parties arising from or related to administering the distribution of such Suspended Funds.

2.10 Assumed Liabilities. Upon Closing, Buyer assumes and hereby agrees to fulfill, perform, be bound by, pay and discharge (or cause to be fulfilled, performed, paid or discharged) all obligations and liabilities of any kind whatsoever of Seller arising from or relating to the Assets or the Companies, whether known or unknown, liquidated or contingent, and regardless of whether the same are deemed to have arisen, accrued or are attributable to periods prior to, on or after the Effective Time, including obligations and liabilities of Seller concerning: (a) the use, ownership or operation of the Assets or the ownership or operation of the Companies, (b) any obligations under or relating to any Contracts, (c) furnishing makeup Hydrocarbons and/or settling and paying for Imbalances according to the terms of applicable operating agreements, gas balancing agreements, Hydrocarbons sales, processing, gathering or transportation Contracts and other Contracts, (d) paying all obligations owed to working interest, royalty, overriding royalty, net profits and other interest owners and operators relating to the Assets, including their share of any revenues or proceeds attributable to production or sales of Hydrocarbons, (e) all Environmental Liabilities, (f) properly plugging, re-plugging and abandoning the Xxxxx, (g) any obligation or liability for the dismantling, decommissioning, abandoning and removing of the Xxxxx or Equipment, (h) any obligation or liability for the cleaning up, restoration and/or remediation of the premises covered by or related to the Assets in accordance with applicable Contracts, Laws and all Environmental Laws, and (i) any obligation or liability regarding permits held by the Companies or transferred to Buyer and relating to the Assets (all of the obligations and liabilities described in this Section 2.10 are collectively referred to as the “Assumed Liabilities”); provided, Buyer does not assume (and Assumed Liabilities shall not include): (i) the Retained Liabilities, (ii) any obligations or liabilities of Seller to the extent that they are attributable to or arise out of the ownership, use or operation of the Excluded Assets, or (iii) any other Claims for which Seller is required to indemnify Buyer pursuant to Section 3.9, Section 3.19, Article 4 or Section 12.1.

Without limiting Seller’s obligations under Section 3.2, following the Closing and upon reasonable prior written notice from Buyer, Seller will (and will cause its Affiliates to) take all reasonable actions to pursue any Claims under any insurance policies under which Buyer or the Companies would be entitled to receive any proceeds (and Buyer shall provide Seller with its reasonable cooperation in connection with such actions) to allow Buyer to benefit from any insurance proceeds payable to any of the Companies as a named insured under any occurrence based liability and property insurance policies of Seller and its Affiliates that name any of the Companies as a named insured. Buyer shall reimburse Seller and its Affiliates for any related out-of-pocket costs and expenses associated with the foregoing.

(a) From and after the Execution Date until the Closing (or earlier termination of this Agreement but subject to the provisions of Section 3.4(b)) and upon obtaining any required consents of Non-Parties, including Non-Party operators of the Assets (with respect to which consents Seller shall use its commercially reasonable efforts to obtain), Seller shall afford to Buyer and its authorized representatives (“Buyer’s Representatives”) reasonable access, during normal business hours, to the Assets, including the Records, and personnel knowledgeable with respect to the Assets (it being agreed that during Buyer’s Representatives’ access to such personnel, Seller shall have the right to have a designated representative of Seller be present), in each case, upon written notice to Seller.

Upon request by Seller, Buyer shall provide evidence of such insurance to Seller prior to entering the lands underlying the Assets.

3.5 General Disclaimer of Title and Environmental Warranties and Representations. Without limiting Buyer’s remedies for either Title Defects as set forth in Section 3.9 or Environmental Defects as set forth in Section 3.19, any remedies of Buyer pursuant to Section 4.2 for the breach of the representation and warranty set forth in Section 6.11, or the special warranty set forth in the Assignment, Seller makes no warranty or representation, express, implied, statutory or otherwise, with respect to Seller’s title to any of the Assets or the environmental condition or compliance with Environmental Laws of the Assets, and Buyer hereby acknowledges and agrees that Buyer’s sole remedy for any Title Defect (except for the special warranty of title set forth in the conveyance documents) or Environmental Defect with respect to any of the Assets shall be the remedies set forth in Sections 3.9, 3.19 and Section 4.2 for the breach of the representation and warranty set forth in Section 6.11, and Buyer hereby expressly waives and disclaims all other rights and remedies that Buyer may have with respect to any such Title Defect or Environmental Defect. Buyer acknowledges and agrees that (i) Buyer will not assert any claim under the special warranty set forth in the Assignment for any matters that do not exceed the Individual Indemnity Threshold, (ii) Buyer will not be entitled to make a claim under the special warranty for any amount which, together with all claims of Buyer under this Agreement and the Operative Documents, exceeds the Base Purchase Price, and (iii) the aggregate value of all claims made under the special warranty with respect to any Asset shall not exceed the Allocated Value of such Asset.

3.6 Title Defect Notices. From the Execution Date and until 5:00 p.m. Houston, Texas time on such date that falls 45 Days after the Execution Date (the “Defect Claim Date”), Seller shall provide Buyer with access to its “North Shepherd Record Center” from 7:30 a.m. to 10:00 p.m., seven days a week and other access as is reasonably requested or otherwise agreed to by the Parties. On or before 5:00 p.m. Houston, Texas time on the Defect Claim Date, Buyer must deliver claim notices to Seller meeting the requirements of this Section 3.6 (collectively, the “Title Defect Notices” and individually, a “Title Defect Notice”) setting forth any matters that, in Buyer’s reasonable opinion, constitute Title Defects and which Buyer intends to assert as a Title Defect pursuant to this Section 3.6. For all purposes of this Agreement and notwithstanding anything herein to the contrary, subject to the special warranty of title set forth in the Assignment, Buyer shall be deemed to have waived, and Seller shall have no liability for, any Title Defect that Buyer fails to assert as a Title Defect by a Title Defect Notice received by Seller on or before the Defect Claim Date. To be effective, each Title Defect Notice shall be in writing, and shall include (a) a clear description of the alleged Title Defect(s), (b) the Xxxxx and Well

Locations affected by the Title Defect (each a “Title Defect Property”), (c) the Allocated Value of each Title Defect Property, (d) supporting documents reasonably necessary for Seller to verify the existence of the alleged Title Defect(s), and (e) the amount by which Buyer reasonably believes the Allocated Value of each Title Defect Property is reduced by the alleged Title Defect(s) and the computations upon which Buyer’s belief is based. To give Seller an opportunity to commence reviewing and curing Title Defects, Buyer agrees to use reasonable efforts to give Seller, on or before the end of each calendar week prior to the Defect Claim Date, written notice of all Title Defects discovered by Buyer during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Defect Claim Date. Buyer shall also promptly furnish Seller with written notice of any Title Benefit that is discovered by any of Buyer’s or any of its Affiliate’s employees, Buyer’s Representatives, title attorneys, landmen or other title examiners while conducting Buyer’s due diligence with respect to the Assets prior to the Defect Claim Date.

3.7 Title Benefit Notices. Seller shall have the right, but not the obligation, to deliver to Buyer on or before the Defect Claim Date with respect to each Title Benefit a notice (a “Title Benefit Notice”) including (a) a description of the Title Benefit, (b) the Xxxxx and Well Locations affected by the Title Benefit, and (c) the amount by which Seller reasonably believes the Allocated Value of those Xxxxx and Well Locations is increased by the Title Benefit, and the computations upon which Seller’s belief is based. Seller shall be deemed to have waived all Title Benefits of which it has not given notice on or before the Defect Claim Date.

3.8 Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure at any time prior to Closing (the “Cure Period”), any Title Defects of which it has been advised by Buyer. If Seller believes that it has cured any applicable Title Defect, Seller shall deliver written notice thereof to Buyer, together with supporting documents reasonably necessary for Buyer (as well as any title attorney or examiner hired by Buyer) to verify the cure of such Title Defect. Buyer shall, at or prior to the end of the Cure Period, advise Seller in writing whether it agrees or disputes that any such Title Defect has been so cured; provided that Buyer’s failure to timely respond to Seller’s notice of cure shall be deemed Buyer’s agreement that such Title Defect has been cured and Buyer’s waiver of its Claim with respect to such Title Defect. If Buyer timely notifies Seller of a dispute as to Seller’s attempted cure of any Title Defect, then (subject to Section 3.9), the provisions of Section 3.15 shall apply to such Title Defect.

3.9 Remedies for Title Defects. Subject to Seller’s continuing right to dispute the existence of a Title Defect and/or the Title Defect Amount asserted with respect thereto and subject to the rights of the Parties pursuant to Section 3.15, in the event that any Title Defect timely asserted by Buyer in accordance with Section 3.6 is not waived by Buyer or is not cured on or before Closing, Seller shall, at its sole option (except as otherwise provided below), elect to:

(a) subject to the Individual Title Defect Threshold and the Aggregate Defect Deductible, reduce the Base Purchase Price by an amount (“Title Defect Amount”) determined pursuant to Section 3.12 as being the value of such Title Defect;

(b) upon the agreement of Buyer (provided that Buyer’s agreement shall not be necessary with respect to any Title Defect which constitutes a Title Defect solely due to section (d) in the definition of Title Defect and which has existed for more than ten years from the Effective Time), indemnify Buyer against all Claims resulting from such Title Defect pursuant to an indemnity agreement in a form reasonably agreeable to Seller and Buyer provided, under no circumstances shall Seller’s aggregate liability thereunder exceed the Allocated Value for the Title Defect Property made the subject thereof;

(c) retain the entirety of the Title Defect Property that is subject to such Title Defect, together with all associated Assets, in which event the Base Purchase Price shall be reduced by an amount equal to the Allocated Value of all such Assets (any such Assets which Seller has elected to retain pursuant to this Section 3.9(c), “3.9(c) Assets”);

(d) if applicable, terminate this Agreement pursuant to Section 11.1(d); or

(e) if after the diligent pursuit of other remedies reasonably available to Seller to cure any such Title Defect, Seller reasonably believes that such Title Defect can be cured through a quiet title or similar proceeding, then the applicable cure period with respect to such Title Defect shall be extended to the completion of such quiet title or similar proceeding so long as Seller, at its sole cost and expense, diligently pursues such proceeding and actively progresses the same. Such extension shall be available notwithstanding Seller’s previous attempts to cure such Title Defect without the use of a quiet title or similar proceeding, so long as Seller’s initial attempt to cure such Title Defect was diligently pursued and Seller initiates the quiet title or similar proceeding on or before the end of the initial cure period. If the quiet title proceeding does not vest Defensible Title in the applicable Title Defect Property in Buyer, Seller shall implement one of the remedies set forth in clauses (a) through (d) or exercise one or more of the other rights available to it under Section 3.15.

3.10 Remedies for Title Benefits. With respect to each Well and Well Location affected by Title Benefits reported under Section 3.7, an amount (the “Title Benefit Amount”) equal to the increase in the Allocated Value for such Well or Well Location caused by such Title Benefits, as determined pursuant to Section 3.13, shall be credited against and reduce any Title Defect Amounts. In the event the aggregate amount of Title Benefit Amounts equals or exceeds the aggregate amount of Title Defect Amounts in excess of the Aggregate Defect Deductible, neither Party shall be entitled to an adjustment of the Base Purchase Price with respect to any Title Defect Amounts or Title Benefit Amounts.

3.11 Exclusive Remedy for Title Defects. Except for the special warranty set forth in the Assignment, Section 3.9 sets forth the exclusive rights and remedies of Buyer with respect to any defect, failure, irregularity or encumbrance affecting the title to any Asset including Seller’s failure to have Defensible Title with respect to such Asset, and Buyer hereby expressly waives any and all other rights or remedies with respect thereto.

3.12 Title Defect Amount. The Title Defect Amount resulting from a Title Defect shall be the amount by which the Allocated Value of the affected Title Defect Property is reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following methodology, terms and conditions:

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

(b) if the Title Defect is an encumbrance that is undisputed and liquidated in amount, then the Title Defect Amount shall be the amount necessary to be paid to remove such Title Defect from the Title Defect Property;

(c) if the Title Defect represents a discrepancy between (i) the actual Net Revenue Interest for any Title Defect Property with respect to the Target Formation and (ii) the Net Revenue Interest stated herein with respect to the Target Formation, then the Title Defect Amount shall be the product of (A) the Allocated Value of such Title Defect Property multiplied by (B) 1 minus a fraction, the numerator of which is the actual Net Revenue Interest with respect to the Target Formation and the denominator of which is the Net Revenue Interest stated herein with respect to the Target Formation;

(d) if the Title Defect represents an obligation or encumbrance upon or other defect in title to the Title Defect Property of a type not described above, 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 Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation; provided, if such Title Defect is reasonably capable of being cured, the Title Defect Amount shall not be greater than the reasonable cost and expense of curing such Title Defect;

(e) the Title Defect Amount with respect to a Title Defect Property shall be determined without duplication of any costs or losses included in another Title Defect Amount hereunder; and

(f) notwithstanding anything to the contrary in this Section 3.12, 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.

3.13 Title Benefit Amount. The Title Benefit Amount resulting from a Title Benefit shall be determined in accordance with the following methodology, terms and conditions:

(a) if Buyer and Seller agree on the Title Benefit Amount, then that amount shall be the Title Benefit Amount;

(b) if the Title Benefit represents a discrepancy between (i) the actual Net Revenue Interest for any Well or Well Location with respect to the Target Formation and (ii) the Net Revenue Interest for such Well or Well Location shown herein with respect to the Target Formation, then the Title Benefit Amount shall be the product of (A) the Allocated Value of the affected Well or Well Location multiplied by (B) a fraction, the numerator of which is the actual Net Revenue Interest with respect to the Target Formation and the denominator of which is the Net Revenue Interest for such Well or Well Location with respect to the Target Formation shown herein, minus 1; and

(c) if the Title Benefit cannot be calculated pursuant to subsections (a) or (b) above, then the Title Benefit Amount shall be determined by taking into account the Allocated Value of the subject Asset, the legal effect of the Title Benefit, the potential economic effect of the Title Benefit over the life of the subject Asset, the values placed upon the Title Benefit by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation.

3.14 Thresholds. Notwithstanding anything to the contrary, (a) in no event shall there be any adjustments to the Base Purchase Price or other remedies provided by Seller or available to Buyer for any individual Title Defect for which the Title Defect Amount does not exceed $150,000 (“Individual Title Defect Threshold”); and (b) in no event shall there be any adjustments to the Base Purchase Price or other remedies provided by Seller for any Title Defect that exceeds the Individual Title Defect Threshold or any Environmental Defect that exceeds the Individual Environmental Defect Threshold unless the sum of (i) the Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold, excluding any Title Defects cured by Seller, and (ii) the Environmental Defect Amounts of all such Environmental Defects that exceed the Individual Environmental Defect Threshold, excluding Environmental Defects cured by Seller, exceeds the Aggregate Defect Deductible, after which point Buyer shall be entitled to adjustments to the Base Purchase Price only with respect to such Title Defects and Environmental Defects that exceed the Aggregate Defect Deductible.

3.15 Title Dispute Resolution.

(a) (i) Seller and Buyer shall attempt to agree on all Title Defects, Title Benefits, Title Defect Amounts and Title Benefit Amounts prior to Closing. If Seller and Buyer are unable to agree by Closing, the Title Defect Amounts and Title Benefit Amounts in dispute shall be exclusively and finally resolved pursuant to this Section 3.15 and either Party shall have the right, upon the delivery of written notice to the other Party, to dispute such matter and to invoke the dispute resolution provisions below in this Section 3.15 in order to resolve any such dispute. Any such notice must be delivered on or before the 10th Business Day after Closing.

(ii) There shall be a single arbitrator, who shall be a title attorney (the “Title Arbitrator”) with at least 10 years relevant experience, as selected by mutual agreement of Buyer and Seller within 15 Days after the end of the Cure Period, and absent such agreement, by the CPR. The arbitration proceeding shall be held in Houston, Texas, in accordance with the rules of the CPR to the extent such rules do not conflict with the terms of this Section 3.15. The Title Arbitrator’s determination shall be made within 20 Days after submission of the matters in dispute and shall be binding on and non-appealable by the Parties. In making his/her determination, the Title Arbitrator shall be bound by the rules set forth in Sections 3.11 and 3.12 and, subject to the foregoing, may consider such other matters as in the opinion of the Title Arbitrator are necessary to make a proper determination. The Title Arbitrator, however, may not award the Buyer a greater Title Defect Amount than the Title Defect Amount claimed by Buyer in its applicable Title Defect Notice and may not award Seller a greater Title Benefit Amount than the Title Benefit Amount set forth in the applicable Title Benefit Notice. The Title Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Title Defect, Title Benefit, Title Defect Amounts and/or Title Benefit Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter.

(iii) The Title Arbitrator shall include all legal fees and costs of the prevailing party in its award against the losing party. To the extent that the award of the Title Arbitrator with respect to any Title Defect Amount or Title Benefit Amount is not taken into account as an adjustment to the Base Purchase Price pursuant to Section 2.5, then within 10 Days after the Title Arbitrator delivers written notice to Buyer and Seller of the award with respect to a Title Defect Amount or a Title Benefit Amount, (a) Buyer shall pay to Seller the amount, if any, so awarded by the Title Arbitrator to Seller and (b) Seller shall pay to Buyer the amount, if any, so awarded by the Title Arbitrator to Buyer.

(b) (i) Notwithstanding anything herein to the contrary, if Seller is not able to cure a Title Defect on or prior to Closing, Seller shall have the option, by notice in writing to Buyer on or before Closing, to attempt to cure such Title Defect during the 120 Day period after the Closing (with any such Title Defect being called a “Post-Closing Defect”). In such event, the Title Defect Property to which such Post-Closing Defect pertains shall remain a part of the Assets to be assigned and transferred to Buyer at Closing, the Base Purchase Price shall be reduced by an amount equal to the Allocated Value of such Title Defect Property, and such amount shall be paid into an escrow account (the “Defects Escrow”) established with a federally insured savings or banking institution reasonably acceptable to Buyer and Seller (the “Defects Escrow Agent”) pursuant to the terms of an escrow agreement in a form acceptable to the Defects Escrow Agent and reasonably acceptable to Buyer and Seller (the “Defects Escrow Agreement”). The amount deposited into the Defects Escrow with respect to a Post-Closing Defect will remain therein until released as provided in Section 3.15(b)(ii).

(ii) Buyer will act in good faith and reasonably cooperate with Seller after the Closing to cure a Post-Closing Defect. If Seller and Buyer mutually agree that a Post-Closing Defect has been cured, then within two (2) Business Days after such determination, Seller and Buyer shall execute and deliver all necessary documents to cause the amount withheld in the Defects Escrow with respect thereto (together with any interest earned thereon) to be released to Seller in accordance with the terms of the Defects Escrow Agreement. If Seller and Buyer mutually agree that a Post-Closing Defect has been partially cured, then Seller and Buyer shall reasonably agree upon the portion of the amount retained in the Defects Escrow with respect thereto (together with any interest earned thereon) that should be paid to Buyer to compensate it for the uncured portion thereof (together with interest earned thereon), and the remaining portion of such amount shall be released to Seller (together with any interest earned thereon) in accordance with the terms of the Defects Escrow Agreement. If Seller and Buyer mutually agree that a Post-Closing Defect has not been cured, then within two (2) Business Days after such determination, Seller and Buyer shall execute and deliver all necessary documents to cause the amount withheld in the Defect Escrow with respect thereto (together with any interest earned thereon) to be released to Buyer in accordance with the terms of the Defects Escrow Agreement. If as of the 120th Day following the Closing Date Seller has been unable to cure, or has only partially cured, a Post-Closing Defect (and there is no dispute as to whether or not it has been cured or partially cured), the amount withheld in the Defects Escrow with respect to the uncured portion thereof shall be released to Buyer, and the amount withheld in the Defects Escrow with respect to the cured portion shall be released to Seller (in both cases, together with any interest earned thereon) and, in both cases, in accordance with the terms of the Defects Escrow Agreement. If by such 120th Day Seller and Buyer have not agreed whether there has been a satisfactory resolution of a Post-Closing Defect, then such disagreement shall be resolved

as provided in Section 3.15(a) (provided, rather than any payment being made to the applicable Party pursuant to the last sentence of Section 3.15(a), the amount owed to Buyer and/or Seller shall be released from the Defect Escrow to the applicable Party (together with any interest earned thereon)). If a Post-Closing Defect has not been cured, Seller, at its sole option, may take reassignment of the Title Defect Property (which re-assignment shall be effective as of the Effective Time), together with all associated Assets, in which event (i) the Base Purchase Price shall be reduced by an amount equal to the Allocated Value of such Title Defect Property and (ii) the amount withheld in the Defects Escrow with respect to the Title Defect Property shall be released to Buyer.

3.16 Environmental Assessment.

(a) Upon notice to Seller, Buyer shall have the right to conduct an environmental assessment of all or any portion of the Assets (the “Environmental Assessment”) to be conducted by a reputable environmental consulting or engineering firm approved in advance in writing by Seller; provided, to the extent the conduct of any part of such Environmental Asset requires the consent of any Non-Party, then the conduct of such part shall be subject to obtaining such consent (and Seller shall use its commercially reasonable efforts to obtain such consents). The Environmental Assessment shall be limited to Phase 1 Activities. The Environmental Assessment shall be conducted at the sole cost, risk and expense of Buyer, and shall be subject to Section 3.4(b) and the Indemnity Obligations. Seller shall have the right to be present during the Environmental Assessment of any Asset, and Buyer shall provide Seller advance written notice of the timing of same. Buyer shall maintain, and shall cause its officers, employees, representatives, consultants and advisors to maintain, all information obtained by Buyer pursuant to any Environmental Assessment or other due diligence activity as strictly confidential prior to Closing or in perpetuity if Closing does not occur, unless disclosure of any facts discovered through such Environmental Assessment is required under any applicable Laws or by any Governmental Authority. Buyer shall provide Seller with a copy of the final version of all environmental reports prepared by, or on behalf of, Buyer with respect to any Environmental Assessment conducted with respect to the Assets. If any necessary disclosures under applicable Laws are required prior to Closing with respect to matters discovered by any Environmental Assessment conducted by, for or on behalf of Buyer, Buyer agrees that, to the extent permissible under applicable Law, Seller shall be the responsible party for disclosing such matters to the appropriate Governmental Authorities.

(b) Upon completion of Buyer’s due diligence, Buyer shall at its sole cost and expense and without any cost or expense to Seller or its Affiliates, (i) repair all damage done to the Assets (including the real property and other assets associated therewith) caused by Buyer’s (or any Buyer’s Representatives’) due diligence, (ii) restore the Assets (including the real property and other assets associated therewith) to the approximate same or better condition than they were prior to commencement of Buyer’s (or the Buyer’s Representatives’) due diligence and (iii) remove all equipment, tools or other property brought onto the Assets in connection with Buyer’s (or the Buyer representatives’) due diligence. Any disturbance to the Assets (including the real property and other assets associated therewith) resulting from the due diligence conducted by or on behalf of Buyer will be promptly corrected by Buyer.

3.17 Environmental Defects. If Buyer determines that with respect to the Asset there exists an Environmental Condition (other than with respect to asbestos, asbestos containing materials, or NORM, and excluding any matter set forth on Schedule 6.10) (in each case, an “Environmental Defect”), then on or prior to the Defect Claim Date, Buyer may give Seller a written notice of such Environmental Defect that sets forth the information required by this Section 3.17 (an “Environmental Defect Notice”). For all purposes of this Agreement and notwithstanding anything herein to the contrary, Buyer shall be deemed to have waived any Environmental Defect that Buyer fails to timely and properly assert as an Environmental Defect by an Environmental Defect Notice received by Seller on or before the Defect Claim Date. To be effective, an Environmental Defect Notice must set forth (a) a clear description of the matter constituting the alleged Environmental Defect, (b) a description of each Asset (or portion thereof) affected by the alleged Environmental Defect, (c) the estimated proportionate share attributable to the Assets of the estimated Lowest Cost Response to eliminate the alleged Environmental Defect (the “Environmental Defect Amount”), and (d) supporting documents and reasonably necessary for Seller to verify the existence of the alleged Environmental Defect and the Environmental Defect Amount. Buyer shall furnish Seller, on or before the end of each calendar week prior to the Defect Claim Date, Environmental Defect Notices with respect to any Environmental Defects that any of Buyer’s or any of its Affiliate’s employees, representatives, attorneys, or other environmental personnel or contractors discover or become aware of during the preceding calendar week, which notice may be preliminary in nature and supplemented prior to the Defect Claim Date; provided that notwithstanding this sentence, any Environmental Defect Notice shall be deemed timely if received by Seller prior to the Defect Claim Date.

3.18 Seller’s Right to Cure. Seller shall have the right, but not the obligation, to attempt, at its sole cost, to cure or remediate at any time prior to Closing any Environmental Defects of which it has been advised by Buyer pursuant to an Environmental Defect Notice delivered before the Defect Claim Date. If Seller believes that it has remediated any applicable Environmental Defect, Seller shall deliver written notice thereof to Buyer, together with supporting documents available to Seller and reasonably necessary for Buyer (as well as any environmental consultant hired by Buyer) to verify the remediation of the Environmental Defects. Buyer shall, at or prior to the end of the Cure Period, advise Seller in writing whether it agrees or disputes that the Environmental Defect has been so remediated; provided that Buyer’s failure to timely respond to Seller’s notice of remediation shall be deemed Buyer’s agreement that the Environmental Defect has been remediated and Buyer’s waiver of its Claim with respect to such Environmental Defect. If Buyer timely notifies Seller of a dispute as to Seller’s attempted remediation of any Environmental Defect, then (subject to Section 3.19) the provisions of Section 3.21 shall apply to such Environmental Defect.

3.19 Remedies for Environmental Defects. Subject to Seller’s continuing right to dispute the existence of an Environmental Defect and/or the Environmental Defect Amount asserted with respect thereto and subject to the rights of the Parties pursuant to Section 3.21, if any Environmental Defect asserted by Buyer pursuant to an Environmental Defect Notice delivered before the Defect Claim Date is not waived by Buyer or cured on or before the Closing Date, Seller shall, at its sole option (except as otherwise provided below), elect to:

(a) subject to the Individual Environmental Defect Threshold and Aggregate Defect Deductible, reduce the Base Purchase Price by the amount of the Environmental Defect Amount relating to such Environmental Defect as agreed upon by Seller and Buyer or determined pursuant to Section 3.21;

(b) upon the agreement of Buyer, indemnify Buyer against all Claims resulting from such Environmental Defect pursuant to an indemnity agreement in a form reasonably agreeable to Seller and Buyer provided, under no circumstances shall Seller’s aggregate liability thereunder exceed the Allocated Value for the Asset made the subject thereof;

(c) retain the entirety of the Asset that is subject to such Environmental Defect, together with all associated Assets, in which event the Base Purchase Price shall be reduced by an amount equal to the Allocated Value of such Assets (any such Assets which Seller has elected to retain pursuant to this Section 3.19(c), “3.19(c) Assets”);

(d) provided that the Parties shall have agreed to the general plan of remediation with respect to such Environmental Defect and the time period by which such remediation shall take place, cure such Environmental Defect after Closing;

(e) if such Environmental Defect can be cured by paying a fine or penalty, Seller may cure such Environmental Defect by electing to pay such fine or penalty; or

(f) if applicable, terminate this Agreement pursuant to Section 11.1(d).

If Seller elects the option set forth in clause (a) above, then Buyer shall be deemed to have assumed responsibility for all costs and expenses attributable to the remediation of the applicable Environmental Defect and all losses with respect thereto, and Buyer’s obligations with respect thereto shall be deemed to constitute Assumed Liabilities.

3.20 Exclusive Remedies. Except for Buyer’s right to terminate this Agreement pursuant to Section 11.1(d), Section 3.19 sets forth the exclusive rights and remedies of Buyer with respect to Environmental Defects.

3.21 Environmental Dispute Resolution. (a) Seller and Buyer shall attempt to agree on all Environmental Defects and Environmental Defect Amounts prior to Closing. If Seller and Buyer are unable to agree by Closing, the Environmental Defects and Environmental Defect Amounts in dispute shall be exclusively and finally resolved pursuant to this Section 3.21 and either Party shall have the right, upon the delivery of written notice to the other Party, to dispute such matter and to invoke the dispute resolution provisions below in this Section 3.21 in order to resolve any such dispute. Any such notice must be delivered on or before the 10th Business Day after Closing.

(b) There shall be a single arbitrator, who shall be an environmental consultant (the “Environmental Arbitrator”) with at least 10 years relevant experience, as selected by mutual agreement of Buyer and Seller within 15 Days after the end of the Cure Period, and absent such agreement, by the CPR. The arbitration proceeding shall be held in Houston, Texas pursuant to the rules of the CPR to the extent such rules do not conflict with the terms of this Section 3.21. The Environmental Arbitrator’s determination shall be made within 20 Days after submission of the matters in dispute and shall be binding on and non-appealable by the Parties. In making his/her determination, the Environmental Arbitrator shall be bound by the

rules set forth in Sections 3.19 and 3.20 and, subject to the foregoing, may consider such other matters as in the opinion of the Environmental Arbitrator are necessary or helpful to make a proper determination. The Environmental Arbitrator, however, may not award the Buyer a greater Environmental Defect Amount than the Environmental Defect Amount claimed by Buyer in its applicable Environmental Defect Notice or a lesser Environmental Defect Amount than the Environmental Defect Amount claimed by Seller. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and Environmental Defect Amounts submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter.

(c) The Environmental Arbitrator shall include all legal fees and costs of the prevailing party in its award against the losing party. The fees and expenses associated with the Environmental Arbitrator shall be borne equally by the Parties. To the extent that the award of the Environmental Arbitrator with respect to any Environmental Defect Amount is not taken into account as an adjustment to the Base Purchase Price pursuant to Section 2.5, then within 10 Days after the Environmental Arbitrator delivers written notice to Buyer and Seller of the award with respect to an Environmental Defect Amount, (a) Buyer shall pay to Seller the amount, if any, so awarded by the Environmental Arbitrator to Seller and (b) Seller shall pay to Buyer the amount, if any, so awarded by the Environmental Arbitrator to Buyer, and the Party obligated to make a payment pursuant to clause (a) or (b) preceding shall include as a part of such payment interest on the amount due at the Prime Rate from (and including) the Closing Date to (and excluding) the date of payment.

3.22 Environmental Thresholds. Notwithstanding anything to the contrary, (a) in no event shall there be any adjustments to the Base Purchase Price or other remedies provided by Seller or available to Buyer for any individual Environmental Defect for which the Environmental Defect Amount does not exceed $150,000 (“Individual Environmental Defect Threshold”); and (b) in no event shall there be any adjustments to the Base Purchase Price or other remedies provided by Seller for any Environmental Defect that exceeds the Individual Environmental Defect Threshold or any Title Defect that exceeds the Individual Title Defect Threshold unless the sum of (i) the Environmental Defect Amounts of all such Environmental Defects that exceed the Individual Environmental Defect Threshold, excluding any Environmental Defects cured by Seller, and (ii) the Title Defect Amounts of all such Title Defects that exceed the Individual Title Defect Threshold, excluding Title Defects cured by Seller, exceeds the Aggregate Defect Deductible, after which point Buyer shall be entitled to adjustments to the Base Purchase Price only with respect to such Environmental Defects and Title Defects that exceed the Aggregate Defect Deductible.

ARTICLE 4

ALLOCATION OF RESPONSIBILITIES AND INDEMNITIES

4.1 Opportunity for Review. Each Party represents that it has had an adequate opportunity to review the release and indemnity provisions in this Agreement, including the opportunity to submit the same to legal counsel for review and comment. Based upon the foregoing representation, the Parties agree to the provisions set forth below.

4.2 Seller’s Indemnity Obligation. If Closing shall occur, then effective from and after the Closing Date, and subject to the limitations set forth in Section 4.4, Seller shall DEFEND, INDEMNIFY and HOLD HARMLESS Buyer Group from and against any and all Claims arising out of, resulting from, or relating to:

(a) any breach by Seller of Seller’s representations, warranties or covenants set forth in this Agreement;

(b) the ownership, use or operation of the Excluded Assets; and

In no event shall Seller have any obligation to provide indemnification for any matters to the extent accounted for in the Preliminary Settlement Statement or the Final Settlement Statement. Notwithstanding anything herein to the contrary, Buyer acknowledges that it has had the opportunity to conduct due diligence and investigation with respect to the Assets and the Companies.

4.3 Buyer’s Indemnity Obligation. If Closing shall occur, from and after the Closing Date, Buyer shall RELEASE, DEFEND, INDEMNIFY and HOLD HARMLESS Seller Group from and against any and all Claims arising out of, resulting from, or relating to:

(a) any breach by Buyer of Buyer’s representations, warranties or covenants set forth in this Agreement; and

(b) the Assumed Liabilities.

4.4 Claim Periods, Deductible, Threshold, Cap and Materiality Exclusion.

(a) Notwithstanding anything to the contrary, Seller shall have no obligation or liability under Section 4.2(a) for:

(i) any Claim asserted against Seller hereunder, if Buyer has not provided Seller with an Indemnity Claim Notice within 12 months after the Closing Date with respect to such Claim;

(ii) any Claim asserted against Seller hereunder, if such Claim has a value of $750,000 or less (the “Individual Indemnity Threshold”) (and these types of Claims shall not be counted in determining the Indemnity Deductible Amount);

(iii) any Claim asserted against Seller hereunder to the extent the aggregate of all Claims by Buyer does not exceed the Indemnity Deductible Amount, after which point the Buyer Group shall be entitled to defense and indemnification only to the incremental extent of the value of any Claims in excess of the Indemnity Deductible Amount; and

(iv) any Claims that in the aggregate exceed 10% of the Adjusted Purchase Price (for the avoidance of doubt, assuming an Adjusted Purchase Price

of $800 million and aggregate Claims of $120 million, Seller would only be liable for $80 million (10% of the Adjusted Purchase Price) in Claims in excess of the $24 million (3% of the Adjusted Purchase Price) Indemnity Deductible Amount);

provided, the limitations above in Section 4.4(a) shall not apply to any Claim for breach of any of the Specified Representations and Warranties or any Claim for breach of any covenant or similar obligation of Seller occurring prior to the Closing. Notwithstanding anything herein to the contrary, under no circumstances shall the aggregate amount of Seller’s indemnification obligations under Section 4.2(a) exceed the Adjusted Purchase Price.

(b) Any Claim for breach of the Specified Representations and Warranties must be asserted within the applicable statute of limitations and, except as otherwise expressly set forth herein, any Claim for breach of the covenants and similar obligations of Seller occurring prior to the Closing must be asserted within 12 months after the Closing Date.

(c) Notwithstanding anything to the contrary contained in this Article 4, for the purposes of determining if there has been a loss resulting from the breach of any representation or warranty hereunder and the amount of the Claims in respect thereof, the representations and warranties shall, for purposes of this Article 4, be read without giving effect to any materiality, Material Adverse Effect or qualification with a similar meaning contained or incorporated directly or indirectly in such representation or warranty.

(d) The period within which Seller may make Claims against Buyer under the provisions of Section 4.3(b) shall remain open forever, and the Buyer’s Indemnity Obligations under Section 4.3(b) shall survive forever. The period within which Buyer may make Claims against Seller under the provisions of Sections 4.2(b) and 4.2(c) shall remain open forever, and the Seller’s Indemnity Obligations under Sections 4.2(b) and 4.2(c) shall survive forever.

4.5 Notice of Claims. If a Claim is asserted against a Person for which a Party may have Indemnity Obligations under this Agreement (an “Indemnity Claim”), the indemnified Person shall give the indemnifying Party written notice of the underlying Claim setting forth the particulars associated with the underlying Claim (including a copy of the written underlying Claim, if any) as then known by the indemnified Person (“Indemnity Claim Notice”). For Indemnity Claims with respect to which the Individual Indemnity Threshold in Section 4.4 applies, an Indemnity Claim shall be deemed to have been made (subject to the provisions of Section 4.4) upon the indemnified Person’s providing an initial Indemnity Claim Notice to the indemnifying Party stating that the Claim underlying the Indemnity Claim could reasonably be expected to exceed the Individual Indemnity Threshold. The indemnified Person shall, to the extent practicable, give an Indemnity Claim Notice within such time as will allow the indemnifying Party a reasonable period in which to evaluate and timely respond to the underlying Claim; provided, (a) failure to do so shall not affect an indemnified Person’s rights hereunder except for, and only to the extent that, such failure results in insufficient time being available to permit the indemnifying Party to effectively defend against the Claim or otherwise materially prejudices the indemnifying Party’s ability to defend against the Claim through the forfeiture of substantive rights or defenses; and (b) the foregoing shall not extend the time period set forth in Section 4.4(a) (if applicable to the Claim), but if an Indemnity Claim Notice is given to an indemnifying Party within the applicable time period (if any) with respect to such Claim set

forth in Section 4.4(a), such Indemnity Claim Notice shall be effective, subject to the other limitations in Section 4.4 (if applicable), as to costs and expenses incurred or suffered after the expiration of any such time period, with respect to the matter described in such Indemnity Claim Notice.

4.6 Defense of Non-Party Claims. Upon receipt of an Indemnity Claim Notice involving a Non-Party for which an indemnifying Party believes it may have an obligation of indemnity under this Agreement, the indemnifying Party may, if it so elects in accordance with this Section 4.6 within thirty (30) Days from receipt of the Indemnity Claim Notice, admit its liability to defend the indemnified Party against such claim at the sole cost and expense of the indemnifying Party and assume the defense of the Non-Party Claim with counsel selected by the indemnifying Party, and the indemnified Person shall cooperate in all reasonable respects. If any Non-Party Claim involves a fact pattern wherein each Party may have an obligation to indemnify the other Party, each Party may assume the defense of and hire counsel for that portion of the Non-Party Claim for which it may have an obligation of indemnity. In all instances, the indemnified Person may employ separate counsel and/or participate in the defense of any Non-Party Claim; provided, if the indemnifying Party has assumed the defense of a Non-Party Claim pursuant to this Section 4.6 and has agreed to indemnify the indemnified Person, the fees and expenses of counsel employed by the indemnified Person shall be borne solely by the indemnified Person, unless in the opinion of counsel representation of both the indemnified Person and the indemnifying Party would be inappropriate under applicable standards of professional care due to actual or potential differing interests between such parties, in which case the fees and expenses of counsel selected by the indemnified Person (including one appropriate local counsel in each relevant jurisdiction) shall be borne by the indemnifying Party. The indemnifying Party shall pay any judgment entered or settlement with respect to such Non-Party Claim. The indemnifying Party shall not, without the prior written consent of the indemnified Person, consent to the entry of any judgment or enter into any settlement with respect to such Non-Party Claim that does not include a provision whereby the plaintiff or claimant in the matter unconditionally releases the indemnified Person from all liability with respect to such Non-Party Claim in writing. If the indemnifying Party does not admit its liability, or if the indemnifying Party assumes the defense of a Non-Party Claim pursuant to this Section 4.6 but fails to diligently defend against the Non-Party Claim, then the indemnified Person shall have the right to defend, at the sole cost and expense of the indemnifying Party (to the extent the indemnified Person is entitled to indemnification hereunder), the Non-Party Claim by all appropriate proceedings, with counsel of the indemnified Person’s choosing. In such instances, the indemnified Person shall have full control of such defense and proceedings; provided, the indemnified Person shall not settle such Non-Party Claim without the prior written consent of the indemnifying Party; provided further, if the indemnifying Party fails to notify the indemnified Person in writing as to whether or not it consents to such settlement within 10 Days following its receipt of notice of such settlement from the indemnified Person, then such consent shall be deemed given. The indemnifying Party may participate in, but not control, any defense or settlement controlled by an indemnified Person pursuant to this Section 4.6, and the indemnifying Party shall bear its own costs and expenses with respect to such participation. Notwithstanding the other provisions of this Section 4.6, if the indemnifying Party disputes its potential liability to the indemnified Person under this Section 4.6 and if such dispute is resolved in favor of the indemnifying Party, the indemnifying Party shall not be required to bear the costs and expenses of the indemnified Person’s defense pursuant to this Section 4.6.

4.7 Waiver of Certain Damages. Subject to each Party’s obligation to indemnify the other for Claims by a Non-Party, each of the Parties expressly waives and releases, and shall cause its Affiliates to waive and release, special, indirect, consequential, punitive, remote, speculative and exemplary damages, including damages for lost profits of any kind with respect to any dispute arising under, related to, or in connection with this Agreement or any other agreement, contract or instrument contemplated herein or in connection with the transactions contemplated hereby.

4.8 Survival of Claims. Notwithstanding the termination of any Claim period set forth in Section 4.4(a), any Claim properly raised within the applicable time period for such Claim shall survive until such Claim and the Indemnity Obligations with respect thereto are resolved. The Buyer’s Indemnity Obligations under Section 4.3(b) shall survive forever. If no express survival period is set forth with respect to when a Claim may be asserted, the applicable statute of limitations with respect to such Claim will apply.

4.9 Exclusive Remedy. If Closing occurs, the Indemnity Obligations set forth in this Agreement shall be the exclusive remedies of each Party against the other Party for the breach of any representation or warranty or the breach of any covenant set forth in this Agreement occurring prior to the Closing or any Claim arising out of, resulting from or related to the transaction contemplated hereby, and each Party hereby releases, waives and discharges, and covenants not to xxx (and shall cause its Affiliates to release, waive, discharge and covenant not to xxx) with respect to, any Claims not expressly provided for in this Agreement, including Claims under state or federal securities laws and Claims available at common law, in equity or by statute.

4.10 Extent of Indemnification. Without limiting the scope of the indemnification, disclaimer, release and assumption obligations set forth in this Agreement, to the fullest extent permitted by Law, an indemnified Person shall be entitled to indemnification hereunder in accordance with the terms hereof, regardless of whether the Claim or indemnifiable loss giving rise to any such Indemnity Obligation is the result of the sole, partial, active, passive, concurrent or comparative negligence, gross negligence, strict liability, other legal fault or responsibility, or violation of any Law of or by any such indemnified Person.

Buyer acknowledges that Seller owns undivided interests in certain of the Assets, and Buyer agrees that the acts or omissions of the other working interests owners who are not Affiliates of Seller shall not constitute a breach of the provisions of this Section 8.1, nor shall any action required by a vote of working interest owners constitute such a breach so long as Seller has voted its interest in a manner that complies with the provisions of this Section 8.1. Buyer acknowledges that as to those Oil and Gas Properties that are operated by a Person other than Seller or any Affiliate of Seller, the obligations of Seller in this Section 8.1 shall be construed to require that Seller use its commercially reasonable efforts (without being obligated to incur any expense or institute any cause of action) to cause the operator of such Assets to take such actions or render such performance within the constraints of the applicable operating and other applicable agreements and applicable Law.

8.2 Return of Information. In the event of termination of this Agreement, Buyer shall promptly comply with its obligations under the Confidentiality Agreement regarding the return and destruction of Confidential Information.

8.3 Bonds and Other Credit Support.

(a) Buyer acknowledges that various bonds, letters of credit, guarantees and/or cash deposits (collectively, “Security Arrangements”) have been provided by Seller and/or its Affiliates to Governmental Authorities or third parties to secure the payment and performance of plugging and abandonment obligations and other obligations related to the Assets, including those set forth on Schedule 6.23. To the extent Seller or any of its Affiliates has any Seller Obligations with respect to any Security Arrangement set forth on Schedule 6.23, Buyer shall take such actions as are necessary to cause the Seller Obligations arising under such Security Arrangements to be released and terminated concurrent with the Closing.

(b) If Seller becomes aware of any Security Arrangement not listed on Schedule 6.23, Seller shall promptly notify Buyer of the existence of such Security Arrangement and the Parties shall reasonably cooperate in seeking to have the Seller Obligations arising under such Security Arrangements (and such Security Arrangements) to be released and terminated as soon as is reasonably practicable after receipt of such notice. For a Security Arrangement that is (i) necessary for Buyer’s ownership or operation of the Assets in compliance with applicable

Law or applicable Contracts or (ii) which arises from or is related to an Assumed Liability and has a nominal value of less than $1,000,000, then Buyer and Seller shall take all such actions as are necessary to cause the Seller Obligations to be promptly released and terminated, including, if necessary, creating replacement Security Arrangements for the benefit of Seller. For other non-scheduled Security Interests, arising under such Security Arrangements, Buyer shall continue to use all reasonable efforts to work with Seller to have the Seller Obligations arising under such Security Arrangement to be released and terminated as soon as reasonably possible following the Closing. Nothing in this Section 8.3 shall limit Buyer’s indemnification obligations hereunder.

8.4 Record Retention. Buyer, for the longer of seven years following Closing or the complete abandonment of the property covered by the applicable Records, will retain the Records. Each party will provide the other party, its Affiliates, and its and their officers, employees and representatives with access to the Records in its possession during normal business hours for review and copying at the requesting party’s expense and provide the other party, its Affiliates, and its and their officers, employees and representatives with access, during normal business hours, to materials received or produced after Closing relating to any indemnity claim made under Section 4.2 for review and copying at such other party’s expense; provided however, that either party may destroy records in its possession after offering the other party the reasonable opportunity to take possession of such records, at such other party’s expense.

8.5 Notifications. Buyer will notify Seller promptly after the discovery by Buyer that any representation or warranty of Seller contained in this Agreement is, becomes or will be untrue in any material respect on or before the Closing Date.

8.6 Release of Liens. Concurrent with the Closing, all liens and security interests (if any) encumbering any of the Assets and securing any debt facilities maintained by Seller or any Affiliate of Seller shall be terminated; provided, the preceding provision shall not modify the terms of Section 8.3.

8.7 Consents.

(a) Seller shall use commercially reasonable efforts to procure all consents required to assign and transfer the Assets from Seller to Buyer (including the Specified Consent), and Buyer shall reasonably cooperate with Seller in seeking to obtain such consents, but, in each case, except as otherwise agreed, (x) without being obligated to pay any consideration or waive or release any material right or privilege to obtain such consent and (y) without giving rise to or imposing any Buyer Incremental Cost. If the Parties are not able to effect the assignment of any of the Assets at Closing due to the lack of a required Non-Party consent to transfer the same, then, except as otherwise provided herein, such Assets shall not be deemed assigned at Closing; provided, however, that for up to 180 Days after Closing, Seller shall use commercially reasonable efforts to institute alternative arrangements, as mutually agreed with Buyer, intended to put the Parties in substantially the same economic position as if such non-assigned Asset (other than the Contract subject to the Specified Consent) had been assigned. If at the end of such 180 Day period the required consent has not been obtained, then the Parties shall discuss in good faith what further mutually agreeable actions (if any) will be taken with respect to such Asset (other than the Contract subject to the Specified Consent).

(b) As to any Contract for which consent is required, subject to Sections 8.7(c), (d) and (e), until any such consent is obtained, to the extent permissible under Law and under the terms of such Contract, Seller shall use commercially reasonable efforts post-Closing: (i) to continue to perform at the reasonable direction of and for the benefit of Buyer the liabilities and obligations under or with regard to such Contract and enforce at the reasonable direction of and for the benefit of Buyer any and all claims, rights and benefits under such Contract, and (ii) hold such Contract in trust for the benefit of Buyer and shall promptly forward to Buyer any monies or other benefits received that are attributable to such Asset. Subject to compliance with the prior sentence, Buyer shall promptly reimburse Seller for, and shall RELEASE, DEFEND, INDEMNIFY and HOLD HARMLESS Seller Group from and against, any and all Claims incurred by Seller or any member of the Seller Group in connection with any action taken by Seller pursuant to the preceding sentence, IN EACH CASE, REGARDLESS OF THE SOLE, PARTIAL, ACTIVE, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, GROSS NEGLIGENCE, STRICT LIABILITY OR OTHER LEGAL FAULT OR RESPONSIBILITY OF ANY MEMBER OF THE SELLER GROUP. If the foregoing arrangements are not permissible under Law or under the terms of the Contract, then the Parties shall use commercially reasonable efforts to take such other actions or put into place such other arrangements as are permissible with regard to the non-assigned Contract so as to provide the Parties with the same economic results as would otherwise have resulted.

(c) If the assignment of a Lease or Contract is subject to a consent requirement and (i) the Person holding such Consent right is not a Governmental Authority, (ii) the Lease or Contract (other than the Contract subject to the Specified Consent) does not contain language to the effect that the lessor or counterparty thereto (as applicable) will have the right to terminate the Lease or Contract if an assignment is made without the consent requirement being satisfied, and (iii) the failure to obtain such consent would not cause the assignment to Buyer to be void or violate the applicable Lease or Contract, then, in each case, such Lease or Contract (other than the Contract subject to the Specified Consent) shall be assigned to Buyer at Closing and following the Closing Seller and Buyer shall continue the use of commercially reasonable efforts to obtain the required consent (but without giving rise to or imposing any Buyer Incremental Cost) and Buyer shall have no claim against, and Seller shall have no Liability for, the failure to obtain any such consent.

(d) If the assignment of a Lease or Contract (other than the Contract subject to the Specified Consent) is subject to a consent requirement and (i) the Person holding such Consent right is a Governmental Authority, (ii) the Lease or Contract contains language to the effect that the lessor will have the right to terminate the Lease or Contract if an assignment is made without the consent requirement being satisfied, or (iii) the failure to obtain such consent would cause the assignment to Buyer to be void or violate the applicable Lease or Contract, and the required consent is not obtained by the Closing (in such case, a “Consent Agreement”), then, in each case, such Consent Agreement shall be excluded from the Assets to be assigned and sold to Buyer hereunder and the Base Purchase Price shall be reduced by the Allocated Value of the excluded Consent Agreement, if any. Following the Closing, Seller shall continue to use commercially reasonable efforts to procure such consent within 180 Days following the Closing, with Buyer lending reasonable assistance (but without giving rise to or imposing any Buyer Incremental Cost). If at the end of such 180-Day period the required consent has not been obtained, then the Parties shall discuss in good faith what further mutually agreeable actions (if

any) will be taken with respect to such Consent Agreement. If during such 180 Day period the required consent is obtained, then Seller shall notify Buyer and Buyer shall purchase, on or before 10 Business Days following receipt of such notice, the Consent Agreement under the terms of this Agreement for a price equal to the Allocated Value of such Consent Agreement, if any. To the extent such Consent Agreement has not been included in determining the Adjustments to be made pursuant to Section 2.5 (excluding Section 2.5(b)(vi)), then any Adjustments that are specific to such Consent Agreement shall be calculated and contemporaneous with the payment of any such Allocated Value there shall be applied as a deduction to such Allocated Value (if the sum of the downward Adjustments exceeds the sum of the upward Adjustments) the net amount resulting from such Adjustments or there shall be applied as an addition to such Allocated Value (if the sum of the upward Adjustments exceeds the sum of the downward Adjustments) the net amount resulting from such Adjustments.

(e) Notwithstanding anything in this Section 8.7 to the contrary, if the Specified Consent is not obtained prior to Closing, then the Assets subject to such Specified Consent shall become Excluded Assets and the Base Purchase Price shall be reduced by the Allocated Value of such Assets in accordance with Section 2.5(b)(vi).

(f) Notwithstanding anything to the contrary, the failure to obtain any required consent for the assignment of a Lease to Buyer shall not constitute a Title Defect.

(g) Solely for purposes of this Section 8.7, Contracts shall be deemed to include Surface Contracts.

8.8 Preferential Purchase Rights.

(a) With respect to each Preferential Purchase Right applicable to the transactions contemplated hereby, Seller shall send, within seven (7) Business Days following the Execution Date, to the holder of each such right a written notice in compliance with the contractual provisions applicable to such Preferential Purchase Right (after providing Buyer with a copy of, and a reasonable amount of time to comment on, each such notice).

(b) If, prior to Closing, any holder of a Preferential Purchase Right notifies Seller that it intends to consummate the purchase of any part of the Assets to which its Preferential Purchase Right applies (in such case, a “Preferential Right Property”), that Preferential Right Property shall be excluded from the transactions hereunder, and the Base Purchase Price shall be reduced by the Allocated Value of the excluded Preferential Right Property. Seller shall be entitled to all proceeds from the holder of a Preferential Purchase Right who exercises its right to purchase a Preferential Right Property prior to Closing. If the holder of such Preferential Right Property thereafter fails to consummate the purchase of the Preferential Right Property covered by such right on or before 60 Days following the later of the Closing Date or the expiration of the time for exercising such Preferential Purchase Right, then Seller shall notify Buyer and Buyer shall purchase, on or before 10 Business Days following receipt of such notice, the Preferential Right Property under the terms of this Agreement for a price equal to the Allocated Value of such Preferential Right Property.

(c) If, by Closing, a Preferential Purchase Right burdening any Preferential Right Property has not been exercised, the time for exercising such Preferential Purchase Right has not expired and such Preferential Purchase Right has not been waived, then that Preferential Right Property shall be excluded from the transactions hereunder, and the Base Purchase Price shall be reduced by the Allocated Value of such excluded Preferential Right Property. If the time for the exercise of the Preferential Purchase Right with respect to any excluded Preferential Right Property described in this Section 8.8(c) expires following the Closing without the exercise of such Preferential Purchase Right by the holder thereof or such Preferential Purchase Right is waived, then Seller shall notify Buyer and Buyer shall purchase, on or before 10 Business Days following receipt of such notice, such Preferential Right Property from Seller, under the terms of this Agreement for a price equal to the Allocated Value of such Preferential Right Property. All Preferential Right Properties for which applicable Preferential Purchase Rights have been waived prior to Closing, or as to which the period to exercise such right has expired prior to Closing without such right being exercised, shall be sold to Buyer at Closing pursuant to the provisions of this Agreement.

(d) To the extent any Preferential Right Property is purchased by Buyer following the Closing pursuant to Section 8.8(b) or (c) and such Preferential Right Property has not been included in determining the Adjustments to be made pursuant to Section 2.5 (excluding Section 2.5(b)(vi)), then the Adjustments that are specific to such Preferential Right Property shall be calculated and contemporaneous with the payment of the Allocated Value for such Preferential Right Property there shall be applied as a deduction to such Allocated Value (if the sum of the downward Adjustments exceeds the sum of the upward Adjustments) the net amount resulting from such Adjustments or there shall be applied as an addition to such Allocated Value (if the sum of the upward Adjustments exceeds the sum of the downward Adjustments) the net amount resulting from such Adjustments.

8.9 Operatorship. On or before seven Days prior to Closing, Seller shall use reasonable efforts to send notices to all co-working interest owners of the Assets that Seller currently operates (using last known names and addresses from Seller’s files) indicating that it is resigning as operator contingent upon and effective at Closing, and nominating and recommending Buyer (or, at Buyer’s request, an Affiliate of Buyer designated by Buyer) as successor operator, subject to and in reliance on Buyer’s representations, warranties, covenants and agreements in this Agreement. Seller will, upon Buyer’s request, reasonably assist Buyer in its efforts to succeed Seller as operator of the applicable Assets, but in each case (x) without Seller being obligated to pay any consideration or waive or release any right or privilege as part of such assistance and (y) without giving rise to or imposing any Buyer Incremental Cost. Buyer acknowledges and agrees that the co-working interest owners may not allow Buyer to succeed Seller as operator and that Seller has made no representation, warranty or other guarantee that Buyer will succeed Seller as operator. Buyer shall promptly, following Closing, file all appropriate forms, and declarations or bonds with Governmental Authorities relative to its assumption of operatorship if Buyer elects to assume operatorship. For all Seller-operated Assets for which Buyer wishes to assume operatorship, Seller, subject to compliance with all applicable operating agreements, shall execute and deliver to Buyer at Closing and Buyer shall promptly file all the appropriate forms with the applicable Governmental Authorities transferring operatorship of such Assets to Buyer. As to those Assets for which Buyer shall become the operator, the Parties shall use commercially reasonable efforts to cause the transfer of

operatorship to occur as of the date Seller ceases to be obligated to provide operating services pursuant to the Transition Services Agreement. If Buyer elects not to assume operatorship, Buyer shall lend reasonable assistance to Seller in obtaining the transfer of operatorship to the non-Party assuming operatorship.

8.10 Employment Matters.

(a) Buyer agrees that, without Seller’s prior written consent and excepting only as expressly otherwise provided below, until one year after the Closing Date, Buyer shall not, and shall cause its Affiliates not to, directly or indirectly solicit for employment or hire any employee or contractor of Seller or any of its Affiliates, except as to the Available Employees (excluding those who have received severance from Seller or its Affiliates in connection with termination of their employment), as defined in Section 8.10(b) below; provided that, so long as Buyer has not breached its obligations under this Section 8.10(a), neither Buyer nor its Affiliates shall be precluded from (i) making general solicitations to the public or industry that are not directly or indirectly targeted at such employees or (ii) hiring any such employee or contractor who (1) responds to any advertisement to the public or the industry generally that is not directly or indirectly targeted at employees of the Seller or any of its Affiliates, or (2) has been terminated (and not rehired) by Seller or any of its Affiliates (but excluding, for avoidance of doubt, any such Available Employee who has received severance from Seller or its Affiliates in connection with such termination). In the event that Buyer or its Affiliates breach their covenant set forth in the preceding sentence, as liquidated damages, Buyer shall reimburse Seller or its Affiliate, as the case may be, for any severance benefits paid by Seller or its Affiliate, as the case may be, to such Available Employee pursuant to a written severance arrangement in effect on the date hereof.

(b) Buyer or its Affiliates, in its and their sole discretion, may make offers of employment to those certain of the Seller’s or Seller’s Affiliates’ employees whose identity is communicated in a notice to Buyer, which notice shall be delivered by Seller to Buyer on the Execution Date and shall contain each such employee’s name, position, location, and compensation information, and whose employee identification numbers, positions, and locations are set forth on Schedule 8.10(b) (the “Available Employees”). Such offers will be at base salaries or hourly base wages, as applicable, that are no less favorable than the base salaries or hourly base wages, as applicable, of such Available Employees on the Closing Date and employee benefits that are substantially comparable in the aggregate to the employee benefits provided by Buyer or its Affiliates, as applicable, to its similarly situated employees (each such offer, a “Qualifying Offer of Employment”). From and after the date of delivery of such notice until the Closing Date, and subject to all contact and communication with such individuals being coordinated through Seller’s human resources department (which shall promptly cooperate with the reasonable requests of Buyer in respect thereof), Buyer may interview such Available Employees during normal business hours. With respect to each of the Available Employees hired by Buyer, its Affiliates, or any third party contractor on behalf of and at the request of Buyer or its Affiliates (each a “Business Employee”), whose employment with Buyer is terminated during the period commencing on the Closing Date and ending on the first anniversary of the Closing Date, Buyer shall provide such Business Employee with severance benefits equal in value to those that such Business Employee would have received under the EP Energy Severance Plan in effect as of the Execution Date (the “Severance Plan”).

Notwithstanding anything to the contrary contained in this Section 8.10, Buyer shall be solely responsible for any severance payments and benefits which may be payable to any Business Employees as a result of any termination of employment that occurs following the Closing Date and Seller shall be solely responsible for any severance payments or benefits (whether under the Severance Plan or otherwise) which may be payable to any Business Employee as a result of any termination of employment that occurs or is deemed to have occurred under the Severance Plan on or prior to the Closing Date (without any action of Buyer). No later than five Days prior to the Closing Date, Seller shall provide Buyer with the aggregate amount of all severance obligations under the Severance Plan in respect of Available Employees (assuming for such purpose that each Available Employee becomes a Business Employee whose employment is terminated by Buyer on the Day after the Closing Date).

(c) All Business Employees shall become employees of Buyer or its Affiliate, as applicable, as of 12:00 a.m. of the respective local time where the Business Employees are located as of the Closing Date and, at such time, Buyer or its Affiliate, as applicable, shall become responsible for payment of all salaries, wages, and benefits and all other claims, costs, expenses, liabilities and other obligations related to Buyer’s or its Affiliate’s, as applicable, employment of the Business Employee accruing from and after the Closing Date. Seller or its Affiliate, as the case may be, shall be responsible for all salaries, wages, and benefits and all other claims, costs, expenses, liabilities, and other obligations related to the employment of the Business Employees accruing before the Closing Date but excluding the obligations to be assumed by Buyer for each Business Employee pursuant to the provisions hereof.

(d) All Business Employees shall cease active participation in all plans, programs and arrangements of Seller and its Affiliates relating to compensation and employee benefits as of immediately prior to the Closing Date. As of the Closing Date, such Business Employee shall be permitted to participate in the plans, programs, and arrangements of Buyer and its Affiliates relating to compensation and employee benefits for which he or she is eligible pursuant to the terms thereof (each, a “Buyer Plan”).

(e) To the extent any Business Employees become eligible to participate in any Buyer Plan, for purposes of determining eligibility to participate and vesting, service with Seller or its Affiliates shall be treated as service under such Buyer Plan. Such service shall also be recognized for purposes of satisfying any pre-existing conditions, actively-at-work exclusions and waiting periods with respect to participation by and coverage of the Business Employees and their eligible dependents in Buyer Plans, provided that such credit is in compliance with the applicable legal requirements and terms of the Buyer Plans and to the extent permitted by any applicable third party insurance carrier.

(f) As soon as reasonably practicable following the Closing Date, Seller shall pay, or shall cause its Affiliates to pay, to each Business Employee, in cash in a lump sum, the amount of any unused paid time off accrued by such Business Employee as of the Closing Date under Seller’s paid time off policy as in effect immediately prior to the Closing Date. Without limiting the generality of Section 8.10(e), following the Closing, each Business Employee shall be eligible to participate in Buyer’s paid time off policy in accordance with its terms and subject to its conditions, provided that Buyer shall recognize such Business Employee’s service with Seller and its Affiliates for all purposes under such policy, other than in respect of accrual of paid time off for the portion of the year in which the Closing occurs which precedes the Closing Date.

(g) Schedule 8.10(g) sets forth the employee number of each Available Employee in respect of whom contributions have been made to any Benefit Plan that is a tax qualified contribution plan and as to which, as of the Execution Date, any amounts attributable to such contributions are unvested, and as to each such Available Employee the value of such unvested amounts. As required by applicable Law, Seller shall, or shall cause its Affiliates to, adopt such resolutions and take such other actions as are required to provide that, effective as of the Closing, each Business Employee shall be fully vested in any benefit accrued by such Business Employee under any Benefit Plan that is a tax qualified contribution plan as of the Closing, including without limitation any matching contribution made by Seller on behalf of such Business Employee under any Benefit Plan that is a tax-qualified defined contribution plan.

(h) Effective as of the Closing Date, Seller shall terminate the employment of any Available Employee who is not primarily located in Houston, Texas (as indicated by the employee location set forth on Schedule 8.10(b), such employee being a “Field Employee”) and is made and does not accept a Qualifying Offer of Employment. Seller agrees that, without Buyer’s prior written consent and excepting only as expressly otherwise provided below, until one year after the Closing Date, Seller shall not, and shall cause its Affiliates not to, directly or indirectly (i) solicit for employment any employee or contractor of Buyer (excluding those who have received severance from Seller or any of its Affiliates) or any Available Employee or (ii) hire any Business Employee or rehire any Field Employee; provided that, so long as Seller has not breached its obligations under this Section 8.10(h), neither Seller nor its Affiliates shall be precluded from (1) making general solicitations to the public or the industry generally that are not directly or indirectly targeted at Business Employees, or (2) hiring any Business Employee who responds to any such general solicitation or who has been terminated (and not rehired) by Buyer or any of its Affiliates.

8.11 HSR Act. Seller and Buyer shall each promptly, and in any event within fifteen (15) Business Days of the date of this Agreement, make (or cause its relevant Affiliate to make) all required filings, including notifications required under the HSR Act, and prepare applications to each Governmental Authority as to which such filings or applications are necessary or appropriate in the consummation of the transaction contemplated hereby. Each Party shall cooperate with and use all reasonable efforts to assist the other with respect to such filings and applications. Buyer shall bear the cost of all filing or application fees payable to any Governmental Authority with respect to the transaction contemplated hereby, regardless of whether Buyer, Seller or any Affiliate of any of them is required to make the payment.

8.12 Change of Name. As promptly as practicable, but in any case within 60 Days after the Closing Date, Buyer shall use commercially reasonable efforts to (1) eliminate the name “EP Energy” and any variants thereof from the Assets or the business of the Companies, (2) cease using in any way the phrase “EP Energy” with respect to the Assets or the business of the Companies, and (3) remove and cease to use all trademarks associated with Seller or its Affiliates with respect to the Assets or the business of the Companies. Except with respect to such grace period for eliminating existing usage, for the avoidance of doubt, Buyer shall have no right to use any logos, trademarks or trade names belonging to Seller or any of its Affiliates.

8.13 Efforts. Each Party shall use commercially reasonable efforts to take all actions and to do all things necessary to consummate, make effective and comply with all of the terms of this Agreement (including satisfaction, but not waiver, of the conditions to Closing for which it is responsible or of which it otherwise controls). Without limiting the generality of the foregoing, from time to time after Closing, Seller and Buyer shall each execute, acknowledge and deliver to the other such further instruments as may be reasonably requested by the other Party, at such requesting Party’s cost, and as are commercially reasonable to be performed in order to accomplish more effectively the purposes of the transactions contemplated by this Agreement, including those post-Closing actions contemplated by Section 8.7 and Section 8.8. Promptly after Closing, Buyer shall: (a) record the Assignment and all state and federal assignments executed at the Closing in all applicable real property records and/or, if applicable, all state and federal Governmental Authorities and Buyer shall provide to Seller copies of such recorded documents; (b) actively pursue the approval of all Customary Post-Closing Consents from the applicable Governmental Authorities; (c) actively pursue all other consents and approvals that may be required in connection with the assignment of the Assets to Buyer and the assumption of the rights, interests, obligations and liabilities assumed by Buyer hereunder that have not been obtained prior to Closing, provided that Seller shall reasonably cooperate with Buyer in obtaining such other consents and approvals, at Buyer’s sole cost and expense; and (d) deliver all notices that may be required in connection with the assignment of the Assets to Buyer and the assumption of the rights, interests, obligations and liabilities assumed by Buyer hereunder.

8.14 Records in Seller’s Possession. Following Closing, Seller shall grant Buyer reasonable access (at reasonable times and upon reasonable notice) to the Records in Seller’s or its Affiliates’ possession. Within 60 Days after the Closing Date (except as provided below), Seller shall furnish to Buyer originals or legible copies of the Records that are maintained by Seller or its Affiliates; provided, however that with respect any data and records relating (whether in whole or in part) to the Retained Interests, Seller shall retain all originals and provide Buyer with only legible copies thereof. Any and all original Records retained by Seller shall be furnished to Buyer within 30 Days after Seller’s reasonable need for such Records ceases. Buyer shall maintain the Records it acquires for a period of the longer of seven years after Closing or the complete abandonment of the property covered by the applicable Records and shall afford Seller full access to the Records as reasonably requested by Seller. If Buyer desires to destroy any Records within such retention period, Buyer shall notify Seller in writing prior to such destruction and provide Seller the opportunity to take possession of the same at Seller’s sole cost. Notwithstanding the foregoing, Seller shall have no obligation to deliver originals of any Records that are subject to requests or orders from any Governmental Authority not to dispose of such Records.

8.15 Investigation. Buyer acknowledges that it has had the opportunity to conduct due diligence and investigation with respect to the Assets and the Companies.

8.16 Financial Information. From and after the Execution Date until the third anniversary of the Closing Date (the “Access Period”), Seller shall, and shall cause its Affiliates

and their respective officers, directors, managers, employees, agents and representatives to, provide reasonable cooperation to Buyer, its Affiliates and their agents and representatives in connection with Buyer’s or its Affiliates’ filings, if any, that may be required by the Securities and Exchange Commission, under securities Laws applicable to Buyer and its Affiliates (collectively, the “Filings”). During the Access Period, Seller agrees to make available to Buyer and its Affiliates and their agents and representatives any and all books, records, information and documents that are attributable to the Assets in Seller’s or its Affiliates’ possession or control and access to Seller’s and its Affiliates’ personnel, in each case as reasonably required by Buyer, its Affiliates and their agents and representatives in order to prepare, if required, in connection with the Filings, financial statements meeting the requirements of Regulation S-X under the Securities Act, along with any documentation attributable to the Assets or otherwise related to Seller or its Affiliates required to complete any audit associated with such financial statements (it being acknowledged that Seller shall not be required to provide any pro-formas and forward-looking statements). During the Access Period, Seller shall, and shall cause its Affiliates to, provide reasonable cooperation to the independent auditors chosen by Buyer (“Buyer’s Auditor”) in connection with any audit by Buyer’s Auditor of any financial statements of the Assets or of Seller or its Affiliates that Buyer or any of its Affiliates requires to comply with the requirements of the Securities Act or the Securities Exchange Act of 1934 with respect to any Filings. During the Access Period, Seller and its Affiliates shall retain all books, records, information and documents relating to the Assets for the three fiscal years prior to January 1, 2013 and the period from January 1, 2013 through the Closing Date. Buyer will reimburse Seller and its Affiliates, within 10 Business Days after demand in writing therefor, for any reasonable out-of-pocket costs incurred by Seller and its Affiliates in complying with the provision of this Section 8.16. Notwithstanding the foregoing, nothing herein shall expand Seller’s representations, warranties, covenants or agreements set forth in this Agreement or give Buyer, its Affiliates or any Third Party any rights to which it is not entitled hereunder. Buyer hereby releases the members of the Seller Group from, and shall fully protect, defend, indemnify and hold the members of the Seller Group harmless from and against, in each case, any and all Losses (including costs of investigation and reasonable attorneys’ and experts’ fees and expenses) relating to, arising out of or connected with, directly or indirectly, any actions, representations or certifications of Seller’s and its Affiliates’ personnel or auditors with respect to the access, records and cooperation provided pursuant to this Section 8.16, or Buyer’s use of the information contained in such records, or the inclusion of such financial records in any debt or equity offering documents or related materials. THESE INDEMNITY AND DEFENSE OBLIGATIONS APPLY REGARDLESS WHETHER SUCH LOSSES ARE ATTRIBUTABLE TO OR ARISE OUT OF, SOLELY OR IN PART, THE SOLE, ACTIVE, GROSS, PASSIVE, CONCURRENT OR COMPARATIVE NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT OR VIOLATION OF LAW OF OR BY ANY MEMBER OF THE SELLER GROUP; PROVIDED HOWEVER THE FOREGOING INDEMNITY AND DEFENSE OBLIGATIONS SHALL NOT APPLY WITH RESPECT TO THE WILLFUL MISCONDUCT OF ANY MEMBER OF THE SELLER GROUP.

(b) by either Party, if any Law or Order becomes final and effective that prohibits and makes illegal the consummation of the transaction contemplated by this Agreement, upon notification to the non-terminating Party by the terminating Party;

(c) by either Party, if Closing has not occurred by 120 Days following the Execution Date (the “End Date”) through no breach of this Agreement by the terminating Party;

(f) by Buyer, (i) if Seller shall have breached or failed to perform in any material respect any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform would give rise to the failure of a condition set forth in Section 9.2 or (ii) if all of the conditions set forth in Article 9 have been satisfied or waived, as applicable, and Seller nevertheless refuses or fails to Close the transactions contemplated in this Agreement; provided that, in each case, Seller shall first be entitled to 10 Days notice and the opportunity to cure; and provided furthermore, that Buyer shall not be in breach at such time; or

(g) by Seller, (i) if Buyer shall have breached or failed to perform in any material respect any of its representations, warranties, covenants or other agreements contained in this Agreement, which breach or failure to perform would give rise to the failure of a condition set forth in Section 9.1 or (ii) if all of the conditions set forth in Article 9 have been satisfied or waived, as applicable, and Buyer nevertheless refuses or fails to Close the transactions contemplated in this Agreement; provided that, in each case, Buyer shall first be entitled to 10 Days notice and the opportunity to cure and provided furthermore that Seller shall not be in breach at such time.

Buyer and Seller each agree to waive any requirement for the posting of a bond in connection with any such equitable relief in favor of the other Party. If the obligation to Close the transactions contemplated by this Agreement is terminated pursuant to Section 11.1, then, except for those liabilities or obligations that have accrued prior to termination and provisions of this Agreement that by their nature should survive termination, this Agreement shall forthwith become void, and the Parties shall have no further liability or obligation hereunder.

11.3 Confidentiality. Notwithstanding the termination of this Agreement or any other provision of this Agreement to the contrary but subject to the following sentence, the

terms of the Confidentiality Agreement shall remain in full force and effect. If Closing of the transaction contemplated under the terms of this Agreement occurs, the Confidentiality Agreement shall terminate (which termination shall be effective as of Closing) only with respect to Confidential Information covering the Assets.

Buyer and Seller further agree, upon request, to use their commercially reasonable efforts to obtain any certificate or other document from any Taxing Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed with respect to the transactions contemplated.

12.3 Proration of Property Taxes. All ad valorem taxes, real property taxes, and similar obligations with respect to the taxable year or other period during which the Effective Time occurs shall be apportioned between Seller and Buyer as of the Effective Time based on an estimate of the assessment for the immediately preceding taxable year or other period, and the Base Purchase Price shall be reduced at Closing by the amount of such estimated taxes owed by and allocated to Seller for the portion of the taxable year or other period prior to the Effective Time.
