During the forty-five (45) days following the date upon which Seller receives a Notice of Disagreement, Seller and Buyer shall use commercially reasonable efforts to attempt to resolve in writing any differences that they may have with respect to all matters specified in the Notice of Disagreement. If at the end of such forty-five (45) day period (or earlier by mutual agreement), Buyer and Seller have not reached agreement on such matters, the matters that remain in dispute (and only such matters) shall promptly be submitted to KPMG LLP (the “Closing Statement Arbitrator”) for review and final and binding resolution. If KPMG LLP is unable or unwilling to serve as an arbitrator hereunder, then Seller and Buyer shall, in good faith, mutually agree upon an independent national accounting firm who has not represented either Party at any time during the five (5) year period of time immediately preceding its designation hereunder, to serve as the Closing Statement Arbitrator. Buyer and Seller shall, not later than seven (7) days prior to the hearing date set by the Closing Statement Arbitrator, each submit a written brief to the Closing Statement Arbitrator (and a copy thereof to the other Party on the same day) with dollar figures for settlement of the disputes as to the amount of the adjusted Adjustment Amount (together with a proposed Closing Statement and Closing Balance Sheet that reflects such figures) consistent with their respective calculations delivered pursuant to Section 2.9(a). The hearing shall be conducted on a confidential basis. The Closing Statement Arbitrator shall consider only those items or amounts in the Closing Statement and Closing Balance Sheet which were identified in the Notice of Disagreement and which remain in dispute and the Closing Statement Arbitrator’s decision resolving the matters in dispute shall be based upon and be consistent with the terms and conditions in this Agreement. In deciding any matter, the Closing Statement Arbitrator (i) shall be bound by the provisions of this Section 2.9 and the related definitions and (ii) may not assign a value to any disputed item greater than the greatest value for such item claimed by either Seller or Buyer or less than the smallest value for such item claimed by Seller or Buyer in their respective calculations delivered pursuant to Section 2.9(a). The Closing Statement Arbitrator shall render a decision resolving the matters in dispute (which decision shall include a written statement of findings and conclusions) promptly after the conclusion of the hearing, unless the Parties reach agreement prior thereto and withdraw the dispute from arbitration. The Closing Statement Arbitrator shall provide to the Parties explanations in writing of the reasons for its decisions regarding the adjusted Adjustment Amount and shall issue the Final Closing Statement and Final Closing Balance Sheet (each defined below) reflecting such decision. The decision of the Closing Statement Arbitrator shall be (i) final and binding on the Parties and (ii) final and non-appealable for all purposes hereunder; provided, however, that such decision may be reviewed, corrected or set aside by a court of competent jurisdiction, but only if and to the extent that the Closing Statement Arbitrator is found by such court of competent jurisdiction to have made mathematical errors with respect to its decision. The cost of any arbitration (including the fees and expenses of the Closing Statement Arbitrator) under this Section 2.9(b) shall be borne entirely by the Party awarded the smaller percentage of the disputed amount by the Closing Statement Arbitrator. The fees and disbursements of Seller’s independent auditors and other costs and expenses incurred in connection with the services performed with respect to the Closing Statement and Closing Balance Sheet shall be borne by Seller and the fees and disbursements of

Purchase and Sale Agreement

Page 11

Buyer’s independent auditors and other costs and expenses incurred in connection with their preparation of the Notice of Disagreement shall be borne by Buyer. As used in this Agreement, the terms “Final Closing Statement” and “Final Closing Balance Sheet” shall mean the revised Closing Statement and the revised Closing Balance Sheet, respectively, described in Section 2.9(a), as prepared by Seller and as may be subsequently adjusted to reflect any subsequent written agreement between the parties with respect thereto, or if submitted to the Closing Statement Arbitrator, the Arbitrator’s Closing Statement (the “Arbitrator’s Closing Statement”) and the Arbitrator’s Closing Balance Sheet (the “Arbitrator’s Closing Balance Sheet”), each as described in this Section 2.9(b).

(c) Final Settlement. If the amount of the adjusted Adjustment Amount as set forth on the Final Closing Statement exceeds the amount of the Estimated Adjustment Amount paid at Closing, then, within thirty (30) days after the Final Settlement Date, Buyer shall pay to Seller the amount by which the Adjustment Amount as set forth on the Final Closing Statement exceeds the Estimated Adjustment Amount paid at Closing. If the amount of the adjusted Adjustment Amount as set forth on the Final Closing Statement is less than the Estimated Adjustment Amount paid at Closing, then Seller shall pay to Buyer, within five (5) days after the Final Settlement Date, the amount by which the adjusted Adjustment Amount, as set forth on the Final Closing Statement, is less than the Estimated Adjustment Amount shown in the Closing Statement. Any post-Closing payment made pursuant to this Section 2.9(c) shall be made by means of a wire transfer of immediately available funds to a bank account designated by the Party receiving the funds.

2.10 Purchase Price Allocation.

(a) The Parties agree that the transactions contemplated hereby will be treated for federal income Tax purposes as a purchase and sale of the assets of the Company. On or prior to Closing, Seller shall provide to Buyer a schedule setting forth a proposal for an allocation of a portion of the Purchase Price (including any assumed liabilities) among the classes of Company Assets on IRS Form 8594 in accordance with Section 1060 of the Code and the U.S. Treasury Regulations promulgated thereunder (the “Allocation”). If within thirty (30) days after Closing, Buyer notifies Seller in writing that Buyer objects to the allocation set forth in the Allocation, identifying in such writing Buyer’s detailed objections, Buyer and Seller shall use commercially reasonable efforts to resolve such dispute within fifteen (15) days thereafter. In the event that Buyer and Seller are unable to resolve such dispute within such fifteen (15) days, Buyer and Seller shall submit such disputed items for resolution to a mutually agreed internationally recognized national investment banking or accounting firm (“Resolution Firm”); which shall, within thirty (30) days after submission, report to Buyer and Seller its determination on such disputed allocations. The allocations determined by the Resolution Firm shall be conclusive and binding upon Buyer and Seller. Each of Buyer and Seller shall bear all fees and costs incurred by it in connection with the disputed allocations, except that all costs and expenses of the Resolution Firm relating to the disputed allocations shall be borne equally by Buyer and Seller.

(b) If an adjustment is made to the Purchase Price pursuant to this Agreement, the Allocation shall be adjusted accordingly in accordance with Section 1060 of the Code and as mutually agreed by Buyer and Seller based solely on such adjustment. In the event that an

Purchase and Sale Agreement

Page 12

agreement with respect to any adjustment is not reached within thirty (30) days after the Final Settlement Date, any disputed items shall be resolved in the manner described in Section 2.10(a).

(c) Seller and Buyer shall report consistently with the Allocation in all Tax Returns, including IRS Form 8594, which Seller and Buyer shall timely file with the IRS, and neither Seller nor Buyer shall take any position in any such return that is inconsistent with the Allocation, as adjusted, in each case, unless required to do so by a final determination as defined in Section 1313 of the Code, or otherwise with the written consent of the other Party. Not later than ten (10) days prior to the filing of their respective IRS Forms 8594 relating to this transaction, each Party shall deliver to the other Party a copy of its IRS Form 8594.

From and after Closing, Seller shall indemnify, defend, and hold harmless Buyer, its Affiliates, and each of their respective officers, members, managers, partners, directors, employees, and representatives (the “Buyer Indemnified Parties”) against any and all liabilities, damages, losses, costs, and expenses (including reasonable attorneys’ and consultants’ fees and expenses) (“Losses”) incurred or suffered by the Buyer Indemnified Parties as a result of, relating to or arising out of any breach of any representation or warranty made by Seller in Article 3 as though such representation or warranty were made as of the Closing Date (except to the extent that such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall have been made as of such earlier date).

(b) Indemnity Regarding the Company. From and after Closing, Seller shall indemnify, defend, and hold harmless the Buyer Indemnified Parties against any and all Losses incurred or suffered as a result of, relating to, or arising out of (i) any breach of any representation or warranty made by Seller in Sections [Omitted] and [Omitted] and in Section [Omitted] that are [Omitted] (disregarding all materiality and Material Adverse Effect qualifications contained therein) as though such representation or warranty were made as of the Closing Date (except to the extent that such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall have been made as of such earlier date) and (ii) the breach of any covenant or agreement made or to be performed by Seller under this Agreement.

(c) Buyer Indemnity. From and after Closing, Buyer shall indemnify, defend, and hold harmless Seller, the partners of Seller, its and their Affiliates, and each of their respective officers, members, managers, partners, directors, employees, and representatives (the “Seller Indemnified Parties”) against any and all Losses incurred or suffered by the Seller Indemnified Parties as a result of, relating to or arising out of (i) any breach of any representation or warranty made by Buyer in this Agreement as though such representation or warranty were made as of the Closing Date (except to the extent that such representations and warranties expressly relate to an earlier date, in which case such representations and warranties shall have been made as of such earlier date), (ii) the breach of any covenant or agreement made or to be performed by Buyer under this Agreement, and (iii) the Company and the ownership and operation of the Company Assets after the Closing.

Purchase and Sale Agreement

Page 32

(a) Express Negligence Rule. The indemnification and waiver provisions in this Article 9 shall be enforceable regardless of whether any Person (including the Person from whom indemnification is sought) alleges or proves the sole, concurrent, contributory, or comparative negligence of the Person seeking indemnification or the sole or concurrent strict liability imposed upon the Person seeking indemnification, except in the case of gross negligence or willful misconduct by such Person.

9.2 Limitations on Liability.

(a) Deductible and Escrow. A Buyer Indemnified Party will not be entitled to indemnity under Section 9.1(b) of this Agreement for Losses with respect to any claim until the aggregate amount of all such finally determined claims plus the aggregate amount of all finally determined claims for Title Defects and Title Defect Amounts under the procedures set forth in Exhibit B exceeds the Deductible, and thereafter, the Buyer Indemnified Parties shall only be entitled to indemnity for the amount in excess of the Deductible, subject to the limitations set forth in this Agreement. If a Buyer Indemnified Party is entitled to indemnity under Section 9.1(b) of this Agreement, any such claim (including any claim pursuant to Section 4.7(viii)) shall be satisfied solely and exclusively against the Indemnity Deposit Escrow Account. Notwithstanding the foregoing provisions of this Section 9.2(b) the limitations set forth on Seller’s indemnification obligations in the previous two sentences shall not apply to Losses resulting from any breach of any representation or warranty of Seller in Sections 4.2(b), 4.3, 4.7(ix) and 4.13(the “Excepted Matters”). Therefore, except for the Excepted Matters, the maximum aggregate liability of Seller under Section 9.1(b) of this Agreement shall not exceed the Indemnity Deposit, and the Buyer Indemnified Parties shall have no further right to indemnity thereunder at such time as all funds have been disbursed from the Indemnity Deposit Escrow Account. Except for Excepted Matters, under no circumstance shall a Buyer Indemnified Party be entitled to recover an indemnity claim arising under Section 9.1(b) of this Agreement directly against Seller.

(b) Survival. The representations and warranties of the Parties under this Agreement shall survive the Closing, except that the representations and warranties of Seller in Article 4 shall terminate at Closing, other than Seller’s representations and warranties (i) in Sections [Omitted] and [Omitted], which shall survive until the end of the 180th day following the Closing Date and (ii) in Sections [Omitted] and [Omitted], which shall survive until the 30th day following the expiration of the applicable statute of limitations (taking into account all applicable extensions or tollings thereof). The covenants and agreements of the Parties in this Agreement shall survive the Closing in accordance with their terms. Notwithstanding the foregoing, any assertion by any Buyer Indemnified Party under Section [Omitted] for any claim (other than a claim based on an Excepted Matter) must be made in a Notice delivered to Seller (or not at all) on or prior to the end of the 180th day following the Closing Date.

(c) Reductions. The amount of any Losses subject to indemnification under this Article 9 shall be reduced or reimbursed, as the case may be, by any third party insurance proceeds and third party recoveries actually received by the Buyer Indemnified Parties with respect to such Losses. Buyer shall, and shall cause the Buyer Indemnified Parties to, use

Purchase and Sale Agreement

Page 33

commercially reasonable efforts to collect any amounts available under such insurance coverage and from such other third party alleged to have responsibility. If a Buyer Indemnified Party receives an amount under insurance coverage or from such third party with respect to Losses that were the subject of indemnification under this Article 9 at any time subsequent to indemnification provided thereunder, then such Buyer Indemnified Party shall promptly reimburse Seller.

(d) Mitigation. Each Indemnified Party shall make reasonable efforts to mitigate or minimize Losses under this Agreement upon and after becoming aware of any event or condition which would reasonably be expected to give rise to any Losses that are indemnifiable under this Article 9; provided, that such Indemnified Party shall not be required to incur extraordinary expense or risk to mitigate or minimize any such Losses. If an Indemnified Party fails to so mitigate an indemnifiable loss under the preceding sentence, the Indemnifying Party shall have no liability for any portion of such loss that reasonably could have been avoided had the Indemnified Party made such efforts.

Purchase and Sale Agreement

Page 34

9.3 Procedures. Claims for indemnification under this Agreement shall be asserted and resolved as follows.

(a) Third Party Claim. If any Person entitled to seek indemnification under Section 9.1 (an “Indemnified Party”) receives Notice of the assertion or commencement of any claim asserted against an Indemnified Party by a third party (“Third Party Claim”) in respect of any matter that is subject to indemnification under Section 9.1, the Indemnified Party shall promptly (i) notify the Party obligated to the Indemnified Party pursuant to Section 9.1 above, (the “Indemnifying Party”) of the Third Party Claim and (ii) transmit to the Indemnifying Party Notice (“Claim Notice”) describing in reasonable detail the nature of the Third Party Claim, a copy of all papers served with respect to such claim (if any), the Indemnified Party’s best estimate of the amount of Losses attributable to the Third Party Claim and the basis of the Indemnified Party’s request for indemnification under this Agreement. Failure to timely provide such Claim Notice shall not affect the right of the Indemnified Party’s indemnification hereunder, except to the extent the Indemnifying Party is prejudiced by such delay or omission.

(b) Indemnifying Party. Except with respect to Tax Audits described in Section 7.2, the Indemnifying Party shall have the right to defend the Indemnified Party against such Third Party Claim. If the Indemnifying Party notifies the Indemnified Party that the Indemnifying Party elects to assume the defense of the Third Party Claim (such election to be without prejudice to the right of the Indemnified Party to dispute whether such claim is an identifiable Loss under this Article 9), then the Indemnifying Party shall have the right to defend such Third Party Claim with counsel selected by the Indemnifying Party (who shall be reasonably satisfactory to the Indemnified Party), by all appropriate proceedings, to a final conclusion or settlement at the discretion of the Indemnifying Party in accordance with this Section 9.3(b). The Indemnifying Party shall have full control of such defense and proceedings, including any compromise or settlement thereof; provided that the Indemnifying Party shall not enter into any settlement agreement or consent to the entry of any judgment with respect thereto without the written consent of the Indemnified Party (which consent shall not be unreasonably withheld, conditioned, or delayed) that (i) does not result in a final resolution of the Indemnified Parties’ liability to the third party with respect to the claim (including, in the case of a settlement, an unconditional written release of the Indemnified Party from all further liability in respect of such claim) or (ii) may materially and adversely affect the Indemnified Party (other than as a result of money damages covered by the indemnity). If requested by the Indemnifying Party, the Indemnified Party agrees, at the sole cost and expense of the Indemnifying Party, to cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim which the Indemnifying Party elects to contest pursuant to this Section 9.3(b), including the making of any related counterclaim against the Person asserting the Third Party Claim or any cross complaint against any Person. The Indemnified Party may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 9.3(b), and the Indemnified Party shall bear its own costs and expenses with respect to such participation.

(c) Indemnified Party. Except with respect to Tax Audits described in Section 7.2, if the Indemnifying Party does not notify the Indemnified Party that the Indemnifying Party elects to defend the Indemnified Party pursuant to Section 9.3(b), then the Indemnified Party shall have the right to defend, and be reimbursed for its reasonable cost and expense (but only if the Indemnified Party is actually entitled to indemnification hereunder) in regard to the Third Party Claim with counsel selected by the Indemnified Party (who shall be reasonably satisfactory to the Indemnifying Party), by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnified Party. In such circumstances, the Indemnified Party shall defend any such Third Party Claim in good faith and have full control of such defense and proceedings; provided, however, that the Indemnified Party may not enter into any compromise or settlement of such Third Party Claim if indemnification is to be sought hereunder, without the Indemnifying Party’s consent (which consent shall not be unreasonably withheld, conditioned or delayed). The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 9.3(c), and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

(d) Direct Claim. Any claim by an Indemnified Party on account of Losses that does not result from a Third Party Claim (a “Direct Claim”) will be asserted by giving the Indemnifying Party reasonably prompt Notice thereof, but in any event not later than thirty (30) days after the Indemnified Party becomes aware of the events that gave rise to such Direct Claim. Such Notice by the Indemnified Party will describe the Direct Claim in reasonable detail, will include copies of all available material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of damages that has been or may be sustained by the Indemnified Party. The Indemnifying Party will have a period of ten (10) Business Days within which to respond in writing to such Direct Claim. If the Indemnifying Party does not so respond within such ten (10) Business Day period, the Indemnifying Party will be deemed to have rejected such Direct Claim, in which event the Indemnified Party will be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement.

9.4 Waiver of Consequential Damages. With respect to any and all Losses for which indemnification may be available hereunder, no Indemnifying Parties shall have any liability for any consequential, indirect, punitive, exemplary, and special damages with respect to any claim for which an Indemnifying Party may have liability pursuant to this Agreement; provided, however, that this waiver shall not apply to the extent such consequential, indirect, punitive, exemplary or special damages are awarded in a Proceeding brought or asserted by a third party against an Indemnified Party.

(b) No Reliance. Buyer has reviewed and has access to all contracts, documents, records, and information which it has desired to review in connection with its decision to enter into this Agreement, and to consummate the transactions contemplated hereby. Buyer has not relied upon any representation, warranty, statement, advice, document, projection, or other information of any type provided by Seller, or its Affiliates, or any of their Representatives, except for the representations and warranties of Seller set forth in this Agreement. In deciding to enter into this Agreement, and to consummate the transactions contemplated hereby, Buyer has relied solely upon its own knowledge, investigation, and analysis (and that of its Representatives) and not on any disclosure or representation made by, or any duty to disclose on the part of, Seller or its Affiliates, or any of their Representatives, other than the representations and warranties of Seller set forth in this Agreement.

(c) Limited Duties. Any and all duties and obligations which either Party may have to the other Party with respect to or in connection with the Interests, the Company Assets, this Agreement, or the transactions contemplated hereby are limited to those in this Agreement. The Parties do not intend (i) that the duties or obligations of either Party, or the rights of either Party, shall be expanded beyond the terms of this Agreement on the basis of any legal or equitable principle or on any other basis whatsoever or (ii) that any equitable or legal principle or any implied obligation of good faith or fair dealing or any other matter requires either Party to incur, suffer, or perform any act, condition, or obligation contrary to the terms of this Agreement and that it would be unfair, and that they do not intend, to increase any of the obligations of any Party under this Agreement on the basis of any implied obligation or otherwise.

(d) Defects. The Interests and the Company Assets are being conveyed and assigned to and accepted by Buyer in their “as is, where is” condition and state of repair, and with all faults and defects, without, subject to the exception below, any representation, warranty, or covenant of any kind or nature, express, implied, or statutory, including, but not limited to, warranties of marketability, quality, condition, conformity to samples, merchantability, and/or fitness for a particular purpose, all of which are expressly

Purchase and Sale Agreement

disclaimed by Seller and waived by Buyer, except for the representations and warranties of Seller set forth in this Agreement. Buyer recognizes that the Company Assets have been used for oil and gas drilling, production, gathering, pipeline, transportation, storage, and related operations. Physical changes in the Company Assets and in the lands included therein may have occurred as a result of such uses. The Company Assets also may include buried pipelines and other equipment, the locations of which may not be known by Seller or readily apparent by a physical inspection of the Company Assets. It is understood and agreed that Buyer shall have inspected prior to Closing (or shall be deemed to have waived its right to inspect) the leases, equipment, pipelines, and the associated premises included in the Company Assets and satisfied itself as to their physical and environmental condition, both surface and subsurface, and that Buyer shall accept all of the same in their “as is, where is” condition and state of repair, and with all faults and defects, including, but not limited to, the presence of naturally occurring radioactive material and man-made material fibers, subject to the representations and warranties of Seller set forth in this Agreement.

(e) Additional Disclaimers. Seller makes no representation, covenant, or warranty, express, implied, or statutory, (i) as to the accuracy or completeness of any data or records delivered to Buyer with respect to the Company or the Company Assets, or (ii) concerning the quality or quantity of hydrocarbon reserves, if any, attributable to the Company Assets, or the ability of the Company Assets to produce hydrocarbons, or the product prices which the Company is or will be entitled to receive from the sale of any such hydrocarbons.

9.6 Exclusive Remedy and Release. The indemnification and remedies set forth in Section 6.3, this Article 9, and Exhibit B shall constitute the sole and exclusive post-Closing remedies of the Parties with respect to any breach of representation or warranty or non-performance of any covenant or agreement contained in this Agreement. Except as provided in this Agreement, if the Closing occurs, each Party hereby waives, releases, acquits, and forever discharges the other Party, its partners, their Affiliates, and its and their officers, directors, members, managers, partners, employees, or agents, or any other Person acting on behalf of such other Party, of and from any and all claims, actions, causes of action, demands, rights, damages, costs, expenses, Losses, or compensation whatsoever, whether direct or indirect, known or unknown, foreseen or unforeseen, which Buyer or the Company or Seller, as applicable, may have or which may arise in the future directly or indirectly arising out of the transactions contemplated hereby, including any of the foregoing that is from or relating to the possession, use, handling, management, disposal, investigation, remediation, cleanup, or release of any Constituents of Concern or any Environmental Law applicable thereto.

(b) by Buyer, upon Notice to Seller, if there has been a material breach by Seller of any representation, warranty, or covenant contained in this Agreement that has prevented the satisfaction of any condition to the obligations of Buyer at the Closing and, if such breach is of a character that it is capable of being cured, such breach has not been cured by Seller within thirty (30) days after Notice thereof from Buyer;

(c) by Seller, upon Notice to Buyer, if there has been a material breach by Buyer of any representation, warranty, or covenant contained in this Agreement that has prevented the satisfaction of any condition to the obligations of Seller at the Closing and, if such breach is of a character that it is capable of being cured, such breach has not been cured by Buyer within thirty (30) days after Notice thereof from Seller;

(d) by either Buyer or Seller, upon Notice to the other Party, if any Governmental Authority having competent jurisdiction has issued a final, non-appealable Order, decree, ruling or injunction (other than a temporary restraining order) or taken any other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such injunction shall have become final and non-appealable; or

(e) by either Buyer or Seller, upon Notice to the other Party, if the transactions contemplated at the Closing have not been consummated by February 29, 2012, provided that neither Buyer nor Seller will be entitled to terminate this Agreement pursuant to this Section 10.1(e) if such Person’s breach of this Agreement has prevented the consummation of the transactions contemplated by this Agreement; or

(f) by Seller, upon Notice to Buyer, if the sum of all Title Defect Amounts contained in any Defect Notice less the sum of all Title Benefit Amounts claimed by Seller is equal to or greater than [Omitted] of the Base Purchase Price; or

(g) by Buyer, upon Notice to Seller, if the sum of all Title Defect Amounts contained in any Defect Notice and determined to be valid less the sum of all Title Benefit Amounts claimed by Seller and determined to be valid is equal to or greater than [Omitted] of the Base Purchase Price; provided that for purposes of determining the validity of the Title Defect Amounts and the Title Benefit Amounts for this Section 10.1(g), (i) Seller shall have a Cure Period ending on October 31, 2011, (ii) if there are any unresolved Title Defects, Title Defect Amounts, Title Benefits, or Title Benefit Amounts at the end of the Cure Period, the Parties shall select and engage a Title Arbitrator by November 7, 2011, (iii) the Title Arbitrator shall make its final and binding determination as to any such unresolved Title Defects, Title Defect Amounts, Title Benefits, or Title Benefit Amounts by November 28, 2011, and (iv) the Closing Date shall be postponed hereunder until December 1, 2011 (plus one additional Business Day for each Business Day that the Title Arbitrator’s determination is delayed beyond November 28, 2011).

10.2 Effect of Termination. Except for this Section 10.2, Section 6.3(c), Section 9.1(d), Section 9.4 and Article 11 except for Section 11.10 (and the definitions related to any of the foregoing), this Agreement shall, upon termination hereof pursuant to Section 10.1,, become of no further force or effect. If this Agreement is terminated (i) by Seller under Section 10.1(c) or (ii) by either Party under Section 10.1(e) if at such xxxx Xxxxxx could have terminated this Agreement under Section 10.1(c) (without regard to any cure periods contemplated therein), then, in either case, the Parties shall instruct the Escrow Agent to release to Seller the Performance Deposit and any interest accrued thereon as partial satisfaction of the damages suffered by Seller as a result of such termination, but the acceptance of the Performance Deposit by Seller shall not limit or affect Seller’s rights to pursue any other rights and remedies available to Seller in respect of such termination (including liability for breach of this Agreement prior to such termination). If this Agreement is terminated under Section 10.1(a), (b), (d), (e) (other than as described in the prior sentence), (f) or (g) then the Parties shall instruct the Escrow Agent to release to Buyer the Performance Deposit and any interest accrued thereon, but the acceptance of the Performance Deposit by Buyer shall not limit or affect Buyer’s rights to pursue any other rights and remedies available to Buyer in respect of such termination (including liability for breach of this Agreement prior to such termination). Nothing in this Section 10.2 will relieve any Party to this Agreement of liability for breach of this Agreement occurring prior to any termination, or for breach of any provision of this Agreement that specifically survives termination hereunder. The Confidentiality Agreement shall not be affected by a termination of this Agreement.

Article 11.

11.2 Assignment. Neither Party shall assign this Agreement or any part hereof without the prior written consent of the other Party; provided that Buyer may assign this Agreement to a non-Texas Affiliate without Seller’s consent, but any such assignment shall not relieve Buyer of any of its obligations under this Agreement or delay, impact, or otherwise adversely affect the timely consummation of the transactions contemplated hereunder. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties and their respective permitted successors and assigns.

11.3 Rights of Third Parties. Except for the provisions of Article 9, which are intended to be enforceable by the Persons respectively referred to therein, nothing expressed or implied in this Agreement is intended or shall be construed to confer upon or give any Person, other than the Parties, any right or remedies under or by reason of this Agreement.

11.4 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Any facsimile copies hereof or signature hereon shall, for all purposes, be deemed originals.

11.5 Entire Agreement. This Agreement (together with the Disclosure Schedule and exhibits to this Agreement) and the Confidentiality Agreement constitute the entire agreement among the Parties and supersede any other agreements, whether written or oral, that may have been made or entered into by or among any of the Parties or any of their respective Affiliates relating to the transactions contemplated hereby.

11.6 Disclosure Schedule. Unless the context otherwise requires, all capitalized terms used in the Disclosure Schedule shall have the respective meanings assigned in this Agreement. No reference to or disclosure of any item or other matter in the Disclosure Schedule shall be construed as an admission or indication that such item or other matter is material or that such item or other matter is required to be referred to or disclosed in the Disclosure Schedule. No disclosure in the Disclosure Schedule relating to any possible breach or violation of any agreement or Law shall be construed as an admission or indication that any such breach or violation exists or has actually occurred. The inclusion of any information in the Disclosure Schedule shall not be deemed to be an admission or acknowledgment by Seller, in and of itself, that such information is material to or outside the ordinary course of the business of the Company or required to be disclosed on the Disclosure Schedule. To the extent reasonably inferable from the reference that it would qualify another representation or warranty, each disclosure in the Disclosure Schedule shall be deemed to qualify all representations and warranties of Seller notwithstanding the lack of a specific cross-reference.

11.7 Amendments. This Agreement may be amended or modified in whole or in part, and terms and conditions may be waived, only by a duly authorized agreement in writing which makes reference to this Agreement executed by each Party.

11.8 Publicity. Buyer, Seller, or any of the partners of Seller may make a press release or other public communication or announcement in connection with the execution of this Agreement, provided that the Person making such release, communication, or announcement provides the other Party reasonable opportunity to review and comment on any such release, communication, or announcement. Except for the foregoing, all press releases or other public communications of any nature whatsoever relating to the transactions contemplated by this Agreement, and the method of the release for publication thereof, shall be subject to the prior written consent of Buyer and Seller, which consent shall not be unreasonably withheld, conditioned, or delayed by such Party; provided, however, that nothing herein shall prevent a Party from publishing such press releases or other public communications as is necessary to satisfy such Party’s obligations at Law or under the rules of any stock or commodities exchange after consultation with the other Party. In the event that a Party believes it is required to issue or make any press release or announcement, such Party shall (i) give prompt notice thereof to the other Party, (ii) allow such other Party reasonable opportunity to review and provide comments with respect to the content of such press release or announcement and (iii) use commercially reasonable efforts to incorporate any reasonable comment from any other Party prior to any release or announcement.

11.9 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. The Parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement,

Purchase and Sale Agreement

Page 41

they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the Parties to the greatest extent legally permissible.

11.10 Specific Performance. Without limiting the effect of Section 9.6 after Closing, the Parties acknowledge and agree, that prior to Closing, (i) each Party would be irreparably harmed by a breach by the other Party of any of their obligations under this Agreement and (ii) the non-breaching Party is entitled to injunctive relief, specific performance, and other equitable remedies against the breaching Party to enforce the performance by the breaching Party of its obligations under this Agreement, and the Parties hereby consent and agree to such injunctive relief, specific performance, and other equitable remedies; provided that, if Buyer is required to consummate the purchase of the Company pursuant to this Section 11.10, the Performance Deposit (together with any interest accrued thereon) shall be applied as a credit against the Closing Payment notwithstanding Buyer’s breach under this Agreement.

11.11 Governing Law; Jurisdiction

(a) Law. This Agreement shall be governed and construed in accordance with the Laws of the State of Texas, without regard to the Laws that might be applicable under conflicts of laws principles.

(b) Forum. The Parties agree that the appropriate, exclusive and convenient forum for any disputes between any of the Parties hereto arising out of this Agreement or the transactions contemplated hereby shall be in any state or federal court in Xxxxxx County, Texas, and each of the Parties hereto irrevocably submits to the jurisdiction of such courts solely in respect of any legal proceeding arising out of or related to this Agreement. The Parties further agree that the Parties shall not bring suit with respect to any disputes arising out of this Agreement or the transactions contemplated hereby in any court or jurisdiction other than the above specified courts. The Parties further agree, to the extent permitted by Law, that a final and nonappealable judgment against a Party in any action or proceeding contemplated above shall be conclusive and may be enforced in any other jurisdiction within or outside the United States by suit on the judgment, a certified or exemplified copy of which shall be conclusive evidence of the fact and amount of such judgment. Except to the extent that a different determination or finding is mandated due to the applicable law being that of a different jurisdiction, the Parties agree that all judicial determinations or findings by a state or federal court in Xxxxxx County, Texas with respect to any matter under this Agreement shall be binding.

(c) Jurisdiction. To the extent that any Party hereto has or hereafter may acquire any immunity from jurisdiction of any court or from any legal process (whether through service or notice, attachment prior to judgment, attachment in aid of execution, execution or otherwise) with respect to itself or its property, each such party hereby irrevocably (i) waives such immunity in respect of its obligations with respect to this Agreement, and (ii) submits to the personal jurisdiction of any court described in Section 11.11(b).
