records and supporting documentation in connection with Seller’s preparation of the Final Post-Closing Purchase Price Adjustment Statement, and shall consult with Buyer in preparing, the Final Post-Closing Purchase Price Adjustment Statement.

(ii) The Final Post-Closing Purchase Price Adjustment Statement shall be subject to Buyer’s review. In reviewing the Final Post-Closing Purchase Price Adjustment Statement, Buyer and its agents and representatives (including, without limitation, accountants and attorneys) shall have the right to communicate with, and to review the work papers, schedules, memoranda and other documents which were prepared by or on behalf of, Seller in its calculation of the Purchase Price Adjustment. Seller and its agents and representatives (including, without limitation, accountants and attorneys) shall also have access to all relevant books and records reasonably required for Buyer to complete its review. Within forty-five (45) days of Buyer’s receipt of the Final Post-Closing Purchase Price Adjustment Statement, Buyer shall by written notice advise Seller of any exceptions (described in reasonable detail) which Buyer may have to the Final Post-Closing Purchase Price Adjustment Statement (“Buyer’s Dispute Notice”).

(iii) For a period of twenty (20) days after Seller’s receipt of a Buyer’s Dispute Notice, the Parties shall use their commercially reasonable efforts to agree on the Purchase Price Adjustment. If the Parties are able to reach agreement on the Purchase Price Adjustment, such resolution shall be final, binding and conclusive.

(iv) If after such twenty (20) day period, Buyer and Seller are unable to reach agreement on the Purchase Price Adjustment, the matter shall be referred to an independent national accounting firm mutually acceptable to the Parties (the “Independent Accounting Firm”). The Parties shall cause the Independent Accounting Firm to submit to them a determination of the Purchase Price Adjustment within thirty (30) days after submission of the matter, and such report and determination shall be final, non-appealable, binding and conclusive on Seller and Buyer. The fees, costs and expenses of the Independent Accounting Firm shall be paid fifty percent (50%) by Buyer and fifty percent (50%) by Seller.

(v) The Purchase Price Adjustment, as finally determined in accordance with this Section 1.10(d), shall be referred to as the “Final Post-Closing Purchase Price Adjustment Amount.”

(A) If the Final Post-Closing Purchase Price Adjustment Amount is less than the Initial Post-Closing Estimated Purchase Price Adjustment Amount, Seller shall pay Buyer an amount equal to such difference.

(B) If the Final Post-Closing Purchase Price Adjustment Amount is greater than the Initial Post-Closing Estimated Purchase Price Adjustment Amount, Buyer shall pay Seller an amount equal to such difference.

(C) The amount payable in accordance with Section 1.10(d)(v)(A) or 1.10(d)(v)(B) above is referred to as the “Final Post-Closing True-Up Amount.”

The Final Post-Closing True-Up Amount shall be paid by the applicable Party within seven (7) days of the final determination of the Final Post-Closing Purchase Price Adjustment Amount by wire transfer of immediately available funds to the account designated by the Party entitled to such payment.

1.11 Additional Proceeds.

(b) If at any time and from time to time prior to the Cut-Off Date, after the last date for which proceeds have been received and reflected in the Final Post-Closing Purchase Price Adjustment Amount, Seller receives any proceeds attributable to the Purchased Assets that are attributable to any period from and after the Effective Time, as calculated in accordance with GAAP and Section 1.7, Seller shall promptly pay to Buyer all such proceeds.

1.12 No Duplicative Effect; Methodologies. The provisions of Section 1.7 through Section 1.11 shall apply in such a manner so as not to give the components and calculations duplicative effect to any item of adjustment and, except as otherwise expressly provided in this Agreement, the Parties covenant and agree that no amount shall be (or is intended to be) included, in whole or in part (either as an increase or reduction) more than once in the calculation of (including any component of) the Purchase Price or Closing Date Aggregate Purchase Price, or any other calculated amount pursuant to this Agreement if the effect of such additional inclusion (either as an increase or reduction) would be to cause such amount to be overstated or understated for purposes of such calculation. The Parties acknowledge and agree that, if there is a conflict between a determination, calculation, methodology, procedure or principle set forth in the definitions contained in this Agreement on the one hand, and those provided by GAAP, on the other hand, a) the determination, calculation, methodology, procedure or principle set forth in this Agreement shall control to the extent that the matter is specifically provided for in this Agreement and b) the determination, calculation or methodology, procedure or principle prescribed by GAAP shall control to the extent that the matter is not so addressed in this Agreement or requires reclassification as an asset or liability to be included in a line item or specific adjustment.

5.7 Access to Purchased Assets and Records. (a) Subject to the terms and conditions of the Confidentiality Agreement dated January 23, 2012 (the “Confidentiality Agreement”), by and between Buyer and Seller, from the date of this Agreement until the Closing, Seller shall cooperate with Buyer and provide Buyer and its representatives, consultants, and current and prospective lenders and advisors, and each of their authorized representatives reasonable access to the Purchased Assets and reasonable access to the Records, but only to the extent that Seller may do so without violating any obligations to any third party and to the extent that Seller has authority to grant such access without breaching any restriction legally binding on Seller. Buyer shall conduct all such inspections and other information gathering described above only (i) (x) during regular business hours and (y) during any weekends and after hours requested by Buyer that can be reasonably accommodated by Seller, and (ii) in a manner which will not unduly interfere with Seller’s operation of the Purchased Assets.

(b) Subject to the Confidentiality Agreement from the date of this Agreement until the Closing, Seller shall afford to Buyer and its officers, employees, agents and current and prospective lenders and each of their authorized representatives reasonable access to the Purchased Assets, including the Records in accordance with Section 5.7(a). During such period, Seller shall also make available to Buyer, upon reasonable notice during normal business hours, Seller’s personnel knowledgeable with respect to the Purchased Assets in order that Buyer may make such diligent investigation as Buyer considers desirable. For those Purchased Assets that are not operated by Seller, Seller shall use commercially reasonable efforts to obtain permission from the operator for Buyer to conduct such inspections but, provided Seller has exercised such commercially reasonable efforts, Seller shall have no liability to Buyer for failure to obtain any such operator’s permission. Upon reasonable notice to Seller, Buyer shall have the right to conduct an environmental assessment of all or any portion of the Purchased Assets (the “Assessment”), to be conducted by a reputable environmental consulting or engineering firm approved in advance in writing by Seller (such approval not to be unreasonably withheld), but only to the extent that Seller may grant such right without violating any obligations to any third party (provided that Seller shall use its commercially reasonable efforts to obtain any necessary third party consents to any Assessment to be conducted by Buyer). The Assessment shall be conducted at the sole cost and expense of Buyer. After completing any Assessment of the Purchased Assets, Buyer shall, at its sole cost and expense, restore the Purchased Assets to their condition prior to the commencement of such Assessment, unless Seller requests otherwise, and shall promptly dispose of all drill cuttings, corings, or other investigative-derived wastes generated in the course of the Assessment. Upon Seller’s written request, 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 Assessment conducted on the Purchased

Assets. In the event that any necessary disclosures under applicable laws are required with respect to matters discovered by any Assessment conducted by, for or on behalf of Buyer, Buyer agrees that Seller shall be the responsible party for disclosing such matters to the appropriate Governmental Entities; provided that, if Seller fails to promptly make such disclosure and Buyer or any of its Affiliates is legally obligated to make such disclosure, Buyer or any of its Affiliates, as applicable, shall have the right to fully comply with such legal obligation. If, as a result of its investigation pursuant to this Section 5.7(b), Buyer determines that with respect to the Purchased Assets, there exists a violation of any Environmental Law (an “Environmental Defect”), Buyer may give Seller notice (“Environmental Defect Notice”) as soon as possible but no later than April 15, 2012, which notice should include a description of the Environmental Defect, a description of the reasonable basis for the Environmental Defect, and reasonable documentation supporting the basis for the Environmental Defect. If Seller receives a timely Environmental Defect Notice, Seller shall elect from among the following options (provided, however that Seller may not elect the option described in sub-section (iii) without Buyer’s consent which shall not be unreasonably delayed, conditioned or denied):

(i) Seller may reduce the Purchase Price by the Environmental Defect Value and include the affected Purchased Asset in the Purchased Assets to be sold and transferred at Closing, in which event Seller shall be released from all further liability or obligation to Buyer with respect to the Environmental Defect, and the Environmental Defect shall become an Environmental Matter.

(ii) Seller may elect to attempt to cure the Environmental Defect post-Closing, in which case, Section 5.7(e) shall apply.

(iii) Seller may notify Buyer, at any time prior to the Closing or the expiration of the Environmental Cure Period, as applicable, in writing that it has elected to indemnify Buyer from all liabilities and obligations arising out of the Environmental Defect. Within ten (10) days following the date that Seller notifies Buyer that Seller has elected to indemnify Buyer under this Section 5.7(b)(iii) Seller shall sell, assign and convey to Buyer, and Buyer shall purchase and accept from Seller, the affected Purchased Asset, in accordance with and subject to the terms and conditions of this Agreement, and Buyer shall pay to Seller the amount by which the Purchase Price was reduced at the initial Closing with respect to such affected Purchased Asset; provided that Buyer consents to indemnity as a cure and to the form of the indemnity which consents shall not be unreasonably denied, delayed or conditioned. If Seller later cures the Environmental Defect to Buyer’s reasonable satisfaction in accordance with this Agreement, the indemnity and all further liability or obligation to Buyer with respect to the affected Purchased Asset shall terminate.

(c) Notwithstanding anything to the contrary, (i) in no event shall there be any adjustments to the Purchase Price or other remedies provided by Seller for any individual Environmental Defect for which the Environmental Defect Value does not exceed $10,000 (“Individual Environmental Defect Threshold”); and (ii) in no event shall there be any adjustments

to the Purchase Price or other remedies provided by Seller for any Environmental Defect for which the Environmental Defect Value exceeds the Individual Environmental Defect Threshold unless (A) the sum of (1) the Environmental Defect Values of all such Environmental Defects that exceed the Individual Environmental Defect Threshold (excluding any Environmental Defects cured by Seller), plus (2) the Title Defect Values of all such Title Defects (excluding any Title Defects cured by Seller) exceeds (B) the Defect Threshold, after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Environmental Defects in excess of the Defect Deductible.

(d) Seller and Buyer shall attempt to agree on all Environmental Defects and Environmental Defect Values. If Seller and Buyer are unable to agree on the existence of an Environmental Defect or the Environmental Defect Value thereof, the Environmental Defects and/or Environmental Defect Amounts in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 5.7(d). There shall be a single arbitrator, who shall be an environmental attorney with at least 10 years experience in environmental matters involving oil and gas producing properties in the regional area in which the affected Purchased Assets are located, as selected by mutual agreement of Buyer and Seller within 15 days after notice requesting arbitration is given by either Party to the other (the “Environmental Arbitrator”). In the event the Parties are unable to mutually agree upon the Environmental Arbitrator within such time period, then each Party will nominate a candidate to be the Environmental Arbitrator, and such candidates so nominated by the Parties shall together determine the Environmental Arbitrator. The arbitration proceeding shall be held in Houston, Texas. The Environmental Arbitrator’s determination shall be made within 20 days after submission of the matters in dispute and shall be final and binding upon both Parties, without right of appeal. In making his determination, the Environmental Arbitrator shall be bound by the rules set forth in this Section 5.7(d) 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 Buyer its share of any greater Environmental Defect Value than the Environmental Defect Value claimed by Buyer in its applicable Environmental Defect Notice. The Environmental Arbitrator shall act as an expert for the limited purpose of determining the specific disputed Environmental Defects and/or Environmental Defect Values submitted by either Party and may not award damages, interest or penalties to either Party with respect to any matter. Seller and Buyer shall each bear its own legal fees and other costs of presenting its case. Each of Seller and Buyer shall bear one-half of the costs and expenses of the Environmental Arbitrator. Nothing herein shall operate to cause the Closing to be delayed on account of any arbitration hereunder and to the extent any adjustments are not agreed upon by the Parties as of the Closing , the Purchase Price or the Allocated Value of the affected Purchased Asset, as applicable, shall not be adjusted therefor as of the Closing or subsequent closing and subsequent adjustments thereto, if any, will be made pursuant to Section 1.10.

(e) Post-Closing Cure of Environmental Defects

(i) If Seller elects to attempt to cure the Environmental Defect post-Closing pursuant to Section 5.7(b)(ii), the Environmental Defect Value shall be deducted from the Purchase Price and paid into an escrow account (the “Defects Escrow”) established with a federally insured savings or banking institution mutually acceptable to

Buyer and Sellers (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”).

(ii) Seller shall have a period of 180 days within which to cure an Environmental Defect. If the Parties mutually agree that an Environmental Defect affecting a Purchased Asset has been cured, then within two Business Days after such determination, the Environmental Defect Value withheld for such Purchased Asset (together with any interest earned thereon) shall be released from the Defects Escrow to Seller in accordance with the terms of the Defects Escrow Agreement. If the Parties mutually agree that an Environmental Defect has not been cured within the 180 day period, then within two Business Days after such determination, the Environmental Defect Value withheld for such Purchased Asset (together with any interest earned thereon) shall be released to Buyer in accordance with the terms of the Defects Escrow Agreement. If, at the end of the 180 day period, the Parties are unable to agree with the sufficiency of the cure of an Environmental Defect, then the Environmental Defect Value withheld for such Purchased Asset (together with any interest earned thereon) shall remain in the Defects Escrow pending resolution of such disagreement in the manner provided in Section 5.7(c) for disagreements with respect to Environmental Defect Values. For avoidance of doubt, the term cure used in this subsection means that the Seller will obtain a “no further action” letter or its equivalent from the relevant Governmental Entity, or if the Parties agree that no such letter or approval is likely to be forthcoming because the provision for such “no further action” letter or its equivalent is not provided for under applicable Environmental Laws, to cure the Environmental Defect to the reasonable satisfaction of Buyer.

(f) Seller and Buyer shall preserve until the fifth (5th) anniversary of the Closing Date all records possessed or to be possessed by such Party relating to any of the Purchased Assets prior to the Closing Date; provided, however, that either Party may preserve such records electronically under its internal policies. After the Closing Date, where there is a legitimate purpose, such Party shall provide the other Party with access, upon prior reasonable written request specifying the need therefor, during regular business hours, to (a) the officers and employees of such Party and (b) the books of account and records of such Party, but, in each case, only to the extent relating to the Purchased Assets prior to the Closing Date, and the other Party and its representatives shall have the right to make copies of such books and records; provided, however, that the foregoing right of access shall not be exercisable in such a manner as to interfere unreasonably with the normal operations and business of such Party. Such records may nevertheless be destroyed by a Party if such Party sends to the other Party written notice of its intent to destroy records, specifying with particularity the contents of the records to be destroyed. Such records may then be destroyed after the thirtieth (30th) day after such notice is given unless another Party objects to the destruction in which case the Party seeking to destroy the records shall deliver such records to the objecting Party.

5.8 Further Assurances. Upon the terms and subject to the conditions hereof, the Parties hereto shall execute such documents and other instruments and take such further actions as may be reasonably required to carry out the provisions hereof and consummate the transactions contemplated by this Agreement.

Seller is not aware of any effort by any third party to have Seller removed as operator of any property for which it is currently operator. Rights and obligations associated with operatorship of such Purchased Assets are governed by operating and similar agreements covering the Purchased Assets and will be determined in accordance with the terms of such agreements. However, Seller will assist Buyer in Buyer’s efforts to succeed, or to cause its affiliate, Linn Operating, Inc., to succeed, Seller as operator of any Xxxxx and units included in the Purchased Assets where Seller currently serves as operator. Buyer shall, promptly following Closing, file all appropriate forms and declarations or bonds with federal and state agencies relative to its assumption of operatorship.

Any sales, excise or other transfer Tax shall be deemed attributable to the period during which the transfer giving rise to such transfer Tax occurred.

(b) Allocation of Purchase Price for Tax Purposes. On or prior to Closing, Seller and Buyer will use commercially reasonable efforts to agree to a Tax allocation on Internal Revenue

Service Form 8594 and any similar form that may be required. If Seller and Buyer agree to such a Tax allocation, Seller and Buyer agree that neither they nor their affiliates will take positions inconsistent with such agreed Tax allocation in notices to government authorities, in audit or other proceedings with respect to Taxes.

(c) Filing of Tax Returns; Payment of Taxes. Seller shall prepare or cause to be prepared all Tax Returns with respect to Applicable Taxes or that could affect a tax liability of Buyer or its direct or indirect owners, if such Tax Return is required to be filed on or before the Closing Date.

(e) Cooperation on Tax Returns and Tax Proceedings. Buyer and Seller shall cooperate fully as and to the extent reasonably requested by the other Party, in connection with the filing of any Tax Returns and any audit, litigation or other proceeding (each, a “Tax Proceeding”) with respect to Taxes relating to or in connection with the Purchased Assets. Such cooperation shall include the retention and (upon the other Party’s request) the provision of such records and information which are reasonably relevant to any such Tax Return or Tax Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Seller shall provide prompt notice to Buyer of any such Tax Proceeding.(f)Section 1031 Exchange. Each Party shall have the right to elect to effect a tax-deferred exchange under Code Section 1031 (an “Exchange”) for the Purchased Assets at any time prior to the Closing Date. If such Party elects to effect an Exchange, the other Party agrees to cooperate with such Party to accommodate such other Party in effectuating the Exchange and to execute escrow instructions, documents, agreements or instruments to effect the Exchange, provided that: (i) the Closing shall not be delayed or affected by reason of the Exchange nor shall the consummation or accomplishment of an Exchange be a condition precedent or condition subsequent to the exchanging Party’s obligations under this Agreement and the exchanging Party’s failure or inability to consummate an exchange for any reason or for no reason at all shall not be deemed to excuse or release the exchanging Party from its obligations under this Agreement, (ii) the exchanging Party shall effect its Exchange through an assignment of this Agreement, or its rights or obligations under this Agreement, to a qualified intermediary, but such assignment shall not release the exchanging Party from any of its liabilities or obligations to the non-exchanging Party under this Agreement or expand any liabilities or obligations of the non-exchanging Party under this Agreement, (iii) no Party shall be required to take an assignment of the purchase agreement for the relinquished or replacement property or be required to acquire or hold title to any

real property for purposes of consummating an Exchange desired by the other Party; and (iv) the exchanging Party shall pay any additional costs, expenses, fees or liabilities that would not otherwise have been incurred by the non-exchanging Party had the exchanging Party not consummated the transaction through an Exchange and the exchanging Party shall indemnify the non-exchanging Party against any such additional costs or liabilities (including reasonable attorney’s fees). No Party shall by this Agreement or acquiescence to an Exchange desired by the other Party have its rights under this Agreement affected or diminished in any manner or be responsible for compliance with or be deemed to have warranted to the exchanging Party that its Exchange in fact complies with Section 1031 of the Code.

(d) curing the Title Defect post-Closing, in which case Section 6.14 shall apply..

6.12 Disputes Relating to Title Defect Value

(a) Buyer and Seller shall attempt to agree on the effect of any efforts of Seller to cure any Title Defects and all Title Defect Values of Title Defects (that are not cured and with respect to which Seller has not elected the option set forth at Section 6.11(b)) on or before the Closing Date. If Seller and Buyer are unable to agree by such date on the effect of any efforts of Seller to cure any Title Defect or the Title Defect Value of any Title Defect not cured and with respect to which Seller has not elected the option set forth at Section 6.11(b), Buyer’s reasonable, good faith estimate of the Title Defect Value for all Title Defects that remain or as to which there is a dispute as of Closing, based on all information reasonably available to Buyer (but which may not, as to any Title Defect, exceed the lesser of the amount asserted by Buyer in a Title Defect Notice or the applicable Allocated Value) (together with all Title Defect Values agreed to by such Seller Party and Buyer as of the Closing, the “Estimated Closing Defect Value”), shall be used to determine the Closing Date Aggregate Purchase Price, and the Title Defects and Title Defect Values in dispute shall be exclusively and finally resolved by arbitration pursuant to this Section 6.12.

(b) Following the date that is one-hundred eighty (180) days after the Closing Date, any Title Defects and Title Defect Values in dispute and not resolved pursuant to Section 6.12(a) shall be submitted to a title attorney with at least ten years experience in oil and gas titles in Texas as selected by mutual agreement of Buyer and the affected Seller Party, or absent such agreement within a ten-day period following the date that is one-hundred eighty (180) days after the Closing Date, by the Houston, Texas office of the AAA (the “Title Arbitrator”). The arbitration proceeding shall be held in Houston, Texas and shall be conducted in accordance with the Commercial Rules, to the extent such rules do not conflict with the terms of this Section. The Title Arbitrator’s determination shall be made within thirty (30) days after submission of the matters in dispute and shall be final and binding on all Parties, without right of appeal. In making his or her determination, the Title Arbitrator shall be bound by the rules set forth in Section 6.7 and may consider such other matters as in the opinion of the Title Arbitrator are necessary or helpful to make a proper determination. Additionally, the Title Arbitrator may consult with and engage disinterested third parties to advise the Title Arbitrator, including title attorneys from other states and petroleum engineers. The Title Arbitrator shall act as an expert for the limited purpose of

determining the specific disputed Title Defects and Title Defect Values submitted by any Party and may not award damages, interest or penalties to any Party with respect to any matter. Each Party shall bear such Party’s own legal fees and other costs of presenting such Party’s case. Buyer and the affected Seller Party shall bear the costs and expenses of the Title Arbitrator in equal parts.

6.13 Adjustment to Purchase Price; Threshold and Deductible. The Purchase Price may be adjusted for Title Defect Values as set forth in Section 6.11(c), Section 6.12 and 6.14; provided, however, notwithstanding anything to the contrary herein, there shall be no cure, remedy, deletion or adjustment to the Purchase Price whatsoever pursuant to Section 6.11(c), Section 6.12. Section 6.14 or otherwise in respect of any Title Defects unless (A) the sum of (1) the Environmental Defect Values of all such Environmental Defects that exceed the Individual Environmental Defect Threshold (excluding any Environmental Defects cured by Seller), plus (2) the Title Defect Values of all such Title Defects (excluding any Title Defects cured by Seller) equals or exceeds (B) one percent (1%) of the Purchase Price (the “Defect Threshold”) after which point Buyer shall be entitled to adjustments to the Purchase Price or other remedies only with respect to such Title Defects in excess of one-half of one percent (0.5%) of the Purchase Price (the “Title Defect Deductible”). For avoidance of doubt, there shall be no adjustment to Purchase Price for Title Defects cured or remedied in accordance with Section 6.11(a) or 6.11(b).

6.14 Post Closing Cure of Title Defects

(a) If Seller elects to attempt to cure the Title Defect post-Closing pursuant to Section 6.11(d), the Title Defect Value shall be deducted from the Purchase Price and paid into an escrow account (the “Title Defects Escrow”) established with a federally insured savings or banking institution mutually acceptable to Buyer and Sellers (the “Title 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 “Title Defects Escrow Agreement”).

(b) Seller shall have a period of 180 days within which to cure a Title Defect.

(i) If the Parties mutually agree that a Title Defect affecting a Purchased Asset has been cured, then within two Business Days after such determination, the Title Defect Value withheld for such Purchased Asset (together with any interest earned thereon) shall be released from the Title Defects Escrow to Seller in accordance with the terms of the Title Defects Escrow Agreement.

(ii) If the Parties mutually agree that a Title Defect has not been cured within the 180 day period, then within two Business Days after such determination, the Title Defect Value withheld for such Purchased Asset (together with any interest earned thereon) shall be released to Buyer in accordance with the terms of the Title Defects Escrow Agreement.

(iii) If, at the end of the 180 day period, the Parties are unable to agree with the sufficiency of the cure of a Title Defect, then the Title Defect Value withheld for

such Purchased Asset (together with any interest earned thereon) shall remain in the Title Defects Escrow pending resolution of such disagreement in the manner provided in Section 6.12(b) for disagreements with respect to Title Defect Values.

6.15 Preference Rights and Transfer Requirements. (a) The transactions contemplated by this Agreement are expressly subject to all validly existing and applicable Preference Rights and Transfer Requirements. Prior to the Closing Date, Seller shall initiate all procedures which are reasonably required to comply with or obtain the waiver of all Preference Rights and Transfer Requirements with respect to the transactions contemplated by this Agreement. Seller shall use their commercially reasonable efforts to obtain all applicable consents and to obtain waivers of applicable Preference Rights; provided, however, Seller shall not be obligated to pay any consideration to (or incur any cost or expense for the benefit of) the holder of any Preference Right or Transfer Requirement in order to obtain the waiver thereof or compliance therewith.

(b) If the holder of a Preference Right elects prior to Closing to purchase the Purchased Asset subject to a Preference Right (a “Preference Property”) in accordance with the terms of such Preference Right, and Seller receives written notice of such election prior to the Closing, such Preference Property will be eliminated from the Purchased Assets and the Purchase Price shall be reduced by the Allocated Value of the Preference Property.

(i) a third party brings any suit, action or other proceeding prior to the Closing seeking to restrain, enjoin or otherwise prohibit the consummation of the transactions contemplated hereby in connection with a claim to enforce a Preference Right;

(ii) a Purchased Asset is subject to a Transfer Requirement that provides that transfer of such Purchased Asset without compliance with such Transfer Requirement will result in termination or other material impairment of any rights in relation to such Purchased Asset, and such Transfer Requirement is not waived, complied with or otherwise satisfied prior to the Closing Date; or

(iii) the holder of a Preference Right does not elect to purchase such Preference Property or waive such Preference Right with respect to the transactions contemplated by this Agreement prior to the Closing Date and the time in which the Preference Right may be exercised has not expired;

then, unless otherwise agreed by Seller and Buyer, the Purchased Asset or portion thereof affected by such Preference Right or Transfer Requirement (a “Retained Asset”) shall be held back from the Purchased Assets to be transferred and conveyed to Buyer at Closing and the Purchase Price to be paid at Closing shall be reduced by the Allocated Value of such Retained Asset. Any Retained Asset so held back at the initial Closing will be conveyed to Buyer at a delayed Closing (which shall become the new Closing Date with respect to such Retained Asset), within ten (10) days following the date on which the suit, action or other proceeding, if any, referenced in clause (i) above is settled or a judgment is rendered (and no longer subject to appeal) permitting transfer of

the Retained Asset to Buyer pursuant to this Agreement and Seller obtains, complies with, obtains a waiver of or notice of election not to exercise or otherwise satisfies all remaining Preference Rights and Transfer Requirements with respect to such Retained Asset as contemplated by this Section (or if multiple Purchased Assets are Retained Assets, on a date mutually agreed to by the Parties in order to consolidate, to the extent reasonably possible, the number of Closings). At the delayed Closing, Buyer shall pay Seller a purchase price equal to the amount by which the Purchase Price was reduced on account of the holding back of such Retained Asset (as adjusted pursuant to Section 1.7 through the new Closing Date therefor); provided, however, if all such Preference Rights and Transfer Requirements with respect to any Retained Asset so held back at the initial Closing are not obtained, complied with, waived or otherwise satisfied as contemplated by this Section within one hundred eighty (180) days after the initial Closing has occurred with respect to any Purchased Asset, then such Retained Asset shall be eliminated from the Purchased Assets and shall become an Excluded Asset, unless Seller and Buyer agree to proceed with a closing on such Retained Asset, in which case Buyer shall be deemed to have waived any objection (and shall be obligated to indemnify the Seller Indemnitees for all Losses) with respect to non-compliance with such Preference Rights and Transfer Requirements with respect to such Retained Asset(s).

6.16 Casualty Loss.

(a) Notwithstanding anything herein to the contrary from and after the Effective Time, if Closing occurs, Buyer shall assume all risk of loss with respect to production of Hydrocarbons through normal depletion (including watering out of any Well, collapsed casing or sand infiltration of any Well) and the depreciation of Equipment due to ordinary wear and tear, in each case, with respect to the Purchased Assets.

(b) If, after the date of this Agreement but prior to the Closing Date, any portion of the Purchased Assets is destroyed by fire or other casualty (other than normal wear and tear, or downhole destruction through downhole risks other than blowouts) or is taken in condemnation or under right of eminent domain, Buyer shall nevertheless be required to close and Seller shall, at Closing, reduce the Purchase Price in an amount equal to the reduction in the value of the Purchased Asset(s) affected; provided that Seller shall retain all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards and other rights against Third Parties arising out of such casualty or taking insofar as with respect to the Purchased Assets. If the parties cannot agree on a reduction, the Seller’s good faith calculation shall be used for purposes of Closing. In the event of downhole destruction through downhole risks other than blowouts, or if Buyer agrees with respect to other casualty or any taking, Seller shall in lieu of a Purchase Price reduction contemplated above, pay to Buyer all sums paid to Seller by Third Parties by reason of such casualty or taking insofar as with respect to the Purchased Assets and shall assign, transfer and set over to Buyer or subrogate Buyer to all of Seller’s right, title and interest (if any) in insurance claims, unpaid awards and other rights against Third Parties arising out of such casualty or taking insofar as with respect to the Purchased Assets; provided, however, that in either case Seller shall reserve and retain (and Buyer shall assign to Seller) all rights, title, interests and claims against Third Parties for the recovery of Seller’s costs and expenses incurred prior to the Closing in pursuing or asserting any such insurance claims or other rights against Third Parties. Seller will fully cooperate with efforts by Buyer to pursue or assert such claims and rights.

8.3 Indemnification Claims.

(a) (i) If any third party notifies any Indemnified Party with respect to any matter (a “Third Party Claim “) that may give rise to a claim for indemnification against an Indemnifying Party under Article VIII, then the Indemnified Party shall promptly give written notification to the Indemnifying Party thereof. Such notification shall be given within ten (10) days after receipt by the Indemnified Party of notice of such Third Party Claim, and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such Third Party Claim and the amount of the claimed damages (if available); provided, however, that no delay or failure on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party of any liability or obligation hereunder except to the extent of any damage or liability caused by or arising out of such failure.

(ii) The Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of such Third Party Claim with counsel reasonably satisfactory to the Indemnified Party; provided that (1) the Indemnifying Party notifies the Indemnified Party in writing within thirty (30) days after the Indemnified Party has given notice of the Third Party Claim that the Indemnifying Party will indemnify the Indemnified Party from and against the Damages the Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim (subject to the provisions of this Article VIII); (2) the ad damnum, if any, is less than or equal to the amount of Damages for which the Indemnifying Party is liable under this Article VIII; (3) the Indemnifying Party provides the Indemnified Party with evidence acceptable to the Indemnified Party that the Indemnifying Party will have the financial resources to defend against the Third Party Claim and fulfill its indemnification obligations hereunder; (4) the Third Party Claim does not involve criminal liability and seeks only money damages and not equitable relief against the Indemnified Party; (5) settlement of, or an adverse judgment with respect to, the Third Party Claim is not, in the good faith judgment of the Indemnified Party, likely to establish a precedential custom or practice adverse to the continuing business interests or the reputation of the Indemnified Party, and (6) the Indemnifying Party conducts the defense of the Third Party Claim actively and diligently.

(iii) If the Indemnifying Party does not, or is not permitted under the terms hereof to, so assume control of the defense of a Third Party Claim, the Indemnified Party shall control such defense.

(iv) The Non-controlling Party may participate in such defense at its own expense. The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Claim and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto.

controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Claim (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Claim. The reasonable fees and expenses of counsel to the Indemnified Party with respect to a Third Party Claim shall be considered Damages for purposes of this Agreement if (1) the Indemnified Party controls the defense of such Third Party Claim pursuant to the terms of this Section 8.3(a) or (2) the Indemnifying Party assumes control of such defense and the Indemnified Party reasonably concludes that the Indemnifying Party and the Indemnified Party have conflicting interests or different defenses available with respect to such Third Party Claim.

The Indemnified Party shall not agree to any settlement of, or the entry of any judgment arising from, any such Third Party Claim without the prior written consent of the Indemnifying Party, which shall not be unreasonably withheld or delayed.

(b) Within twenty (20) days after delivery of the notification of a Third Party Claim as provided in Section 8.3(a)(i) (a “Claim Notice”), the Indemnifying Party shall deliver to the Indemnified Party a response, in which the Indemnifying Party shall: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount to the extent the Claimed Amount may be finally determined at that time, by check or by wire transfer (provided that to the extent the Claimed Amount may not be finally determined at that time, the Indemnifying Party shall pay the Indemnified Party such additional amounts as to constitute the full Claimed Amount at such time as the full Claimed Amount can be finally determined)), (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Agreed Amount, by check or by wire transfer), or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount.

(c) During the thirty (30)-day period following the delivery of a Response that reflects a Dispute, the Indemnifying Party and the Indemnified Party shall use good faith efforts to resolve the Dispute. If the Dispute is not resolved within such thirty (30)-day period, the Indemnifying Party and the Indemnified Party shall discuss in good faith the submission of the Dispute to binding arbitration, and if the Indemnifying Party and the Indemnified Party agree in writing to submit the Dispute to such arbitration, then the provisions of Section 8.3(d) shall become effective with respect to such Dispute. The provisions of this Section 8.3(c) shall not obligate the Indemnifying Party and the Indemnified Party to submit to arbitration or any other alternative dispute resolution

procedure with respect to any Dispute, and in the absence of an agreement by the Indemnifying Party and the Indemnified Party to arbitrate a Dispute, such Dispute shall be resolved in a state or federal court sitting in Houston, Texas, in accordance with Section 11.12.

(d) If, as set forth in Section 8.3(c), the Indemnified Party and the Indemnifying Party agree to submit any Dispute to binding arbitration, the arbitration shall be conducted by a single arbitrator (the “Arbitrator”) in accordance with the Commercial Rules in effect from time to time and the following provisions:

Any award rendered by the Arbitrator shall be final, conclusive and binding upon the parties, and judgment thereon may be entered and enforced in any court of competent jurisdiction (subject to Section 11.12), provided that the Arbitrator shall have no power or authority to (1) award damages in excess of the portion of the Claimed Amount that is subject to such Dispute, (2) award multiple, consequential, punitive or exemplary damages, or (3) grant injunctive relief, specific performance or other equitable relief.

(v) The Arbitrator shall have no power or authority, under the Commercial Rules or otherwise, to (1) modify or disregard any provision of this Agreement, including the provisions of this Section 8.3(d), or (2) address or resolve any issue not submitted by the parties.

(vi) In connection with any arbitration proceeding pursuant to this Agreement, each party shall bear its own costs and expenses, except that the fees and costs of the AAA and the Arbitrator, the costs and expenses of obtaining the facility where the arbitration hearing is held, and such other costs and expenses as the Arbitrator may determine to be directly related to the conduct of the arbitration and appropriately borne jointly by the parties (which shall not include any party’s attorneys’ fees or costs, witness fees (if any), costs of investigation and similar expenses) shall be shared equally by the Indemnified Party and the Indemnifying Party.

(e) Notwithstanding the other provisions of this Section 8.3, if a third party asserts (other than by means of a lawsuit) that an Indemnified Party is liable to such third

party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Party may be entitled to indemnification pursuant to this Article VIII, and such Indemnified Party reasonably determines that it has a valid business reason to fulfill such obligation, then (i) such Indemnified Party shall be entitled to satisfy such obligation, without prior notice to or consent from the Indemnifying Party, (ii) such Indemnified Party may subsequently make a claim for indemnification in accordance with the provisions of this Article VIII and (iii) such Indemnified Party shall be reimbursed, in accordance with the provisions of this Article VIII, for any such Damages for which it is entitled to indemnification pursuant to this Article VIII (subject to the right of the Indemnifying Party to dispute the Indemnified Party’s entitlement to indemnification, or the amount for which it is entitled to indemnification, under the terms of this Article VIII).

(b) The rights to indemnification set forth in this Article VIII shall not be affected by (i) any investigation conducted by or on behalf of an Indemnified Party or any knowledge acquired (or capable of being acquired) by an Indemnified Party, whether before or after the Closing Date, with respect to the inaccuracy or noncompliance with any representation, warranty, covenant or obligation which is the subject of indemnification hereunder or (ii) any waiver by an Indemnified Party of any closing condition relating to the accuracy of representations and warranties or the performance of or compliance with agreements and covenants.

8.5 Limitations.

(c) The rights of the Indemnified Parties under this Article VIII shall be the exclusive remedy of the Indemnified Parties with respect to any and all matters arising out of, relating to, or connected with this Agreement, Seller and its assets and liabilities, including, without limitation, the Purchased Assets and the Assumed Liabilities; provided, however, that notwithstanding any other provision of this Agreement, nothing herein shall limit any claim of any Party for remedies at law or in equity for fraud or intentional misrepresentations.

In the event that an Indemnified Party shall receive funds from any insurance carrier or collateral source with respect to any Damages, any such amounts so received shall be payable to the Indemnifying Party, regardless of when received by the Indemnified Party, up to such amount previously paid by the Indemnifying Party or their Affiliates with respect to such Damages.

(e) Notwithstanding anything to the contrary contained in this Agreement, following a determination that the Indemnifying Party is obligated to indemnify the Indemnified Party pursuant to Sections 8.1(a) or 8.2(a), and subject to the deductible amounts set forth in Sections 8.5(a) or 8.5(b), and solely for purposes of determining the amount of any Damages that are the subject matter of a claim for indemnification hereunder, each representation and warranty in this Agreement and each certificate or document delivered pursuant hereto shall be read without regard and without giving effect to the term(s) “material” or “Material Adverse Effect” in each instance where the effect of including such term(s) would be to make such representation and warranty less restrictive (as if such words and surrounding related words (e.g., “reasonably be expected to,” “could have” and similar restrictions and qualifiers) were deleted from such representations and warranty).

ARTICLE IX

(iii) by Buyer if:

(A) the Closing shall not have occurred on or before June 1, 2012 by reason of the failure of any condition precedent under Section 7.1 or Section 7.2 (unless the failure results primarily from a breach by Buyer of any representation, warranty or covenant contained in this Agreement); or
