On or before November 27, 2017, Purchaser will deliver to Sellers a written report containing all changes that Purchaser proposes to be made to the Preliminary Settlement Statement, if any, together with a brief explanation of any such changes. The Preliminary Settlement Statement, as agreed upon by the Parties, will be used to adjust the Unadjusted Purchase Price at Closing; provided that if the Parties cannot agree on all adjustments set forth in the Preliminary Settlement Statement prior to the Closing for the purpose of determining the Closing Payment, then any adjustments as set forth in the Preliminary Settlement Statement as presented by Sellers will be used to adjust the Unadjusted Purchase Price at Closing.

Sellers may deliver a written report to Purchaser during the same thirty-day (30-day) period reflecting any changes that Sellers propose to be made in such statement as a result of additional information received after the statement was prepared. The Parties shall undertake to agree on the final statement of the Adjusted Purchase Price no later than forty-five (45) days following Purchaser’s receipt of Sellers’ statement delivered hereunder. In the event that the Parties cannot reach agreement as to the final statement of the Adjusted Purchase Price within such period of time, any Party may refer the items of adjustment which are in dispute or the interpretation or effect of this Section 2.5 to a nationally-recognized independent accounting firm or consulting firm mutually acceptable to Purchaser and Sellers (the “Accounting Referee”), for review and final determination by arbitration. The Accounting Referee shall conduct the arbitration proceedings in Houston, Texas in accordance with the AAA Rules, to the extent such rules do not conflict with the terms of this Section 2.5. The Accounting Referee’s determination shall be made within thirty (30) days after submission of the matters in dispute and shall, without limiting Section 9.1(c) or Section 11.3, be final and binding on all Parties, without right of appeal. In determining the amount of any adjustment to the Adjusted Purchase Price, the Accounting Referee shall be bound by the terms of Section 2.4 and may not increase the Adjusted Purchase Price more than the increase proposed by Sellers nor decrease the Adjusted Purchase Price more than the decrease proposed by Purchaser, as applicable. The Accounting Referee shall act as an expert for the limited purpose of determining the specific disputed aspects of Adjusted Purchase Price adjustments submitted by any Party and may not award damages, interest (except to the extent expressly provided for in this Section 2.5), or penalties to any Party with respect to any matter. Sellers and Purchaser shall each bear its own legal fees and other costs of presenting its case.

(a) All adjustments to the Unadjusted Purchase Price described in Section 2.4 shall be made (i) in accordance with the terms of this Agreement and, to the extent not inconsistent with this Agreement and otherwise applicable, in accordance with the United States generally accepted accounting principles using the accrual method of accounting, as consistently applied (the “Accounting Principles”) except that the Accounting Principles shall not apply to any adjustments for Taxes and (ii) without duplication. For the avoidance of doubt, no item that is included in or taken into account in the determination the calculation of Effective Time Working Capital shall be subject to any other adjustment to the Unadjusted Purchase Price. When available, actual figures will be used for the adjustments to the Unadjusted Purchase Price at Closing. To the extent actual figures are unavailable, estimates will be used subject to final adjustments in accordance with the terms hereof.

(b) In making the adjustments contemplated under Section 2.4, the following shall be taken into account to the extent not in conflict or inconsistent with the definitions of Effective Time Working Capital, Working Capital Assets and Working Capital Liabilities; provided, the following shall in no way be construed as a limitation to the definition of any of Effective Time Working Capital, Working Capital Assets and Working Capital Liabilities:

Purchaser shall use commercially reasonable efforts to obtain such Required Consent from the applicable Third Party. If Purchaser or Sellers are unable to obtain any such Required Consent within one hundred ten (110) days after Closing, then Purchaser may elect, by giving written notice to Sellers, to exclude any Asset Seller Assets subject to any such Required Consent, in which case (a) the Parties shall promptly simultaneously execute and deliver such Asset Conveyances, assignments, certificate of non-foreign status, letters in lieu and other instruments described in Section 8.2 and Section 8.3, mutatis mutandis, to effect the assignment of such Asset Seller Assets from Purchaser to the applicable Asset Sellers (which shall include a special warranty of title by, through and under Purchaser), (b) Sellers shall pay and remit to Purchaser the Allocated Value of such re-assigned Asset Seller Assets to Purchaser, net of any post-Effective Time Mineral Proceeds or other revenues attributable to such Asset Seller Assets, (c) such Asset Seller Assets shall be deemed to be deleted from Exhibit A-1, Exhibit A-2, Schedule 1.1(c) and Schedule 1.1(d) and (d) such Asset Seller Assets shall be deemed to constitute Excluded Assets and shall be deemed to be described on Schedule 1.2. If Purchaser fails to provide any notice or election required or permitted under this Section 6.15 with respect to any Required Consent as to any Asset Seller Asset, then Purchaser shall be deemed to have elected to retain any and all such Asset Seller Assets burdened by any such Required Consents discovered by Purchaser prior to the date one hundred ten (110) days after Closing and Purchaser shall be deemed to have waived and released Sellers for any and all liability and Damages arising out of any failure to obtain such Required Consents discovered by Sellers prior to such date.

(a) Sellers acknowledge that Purchaser may be required pursuant to Regulation S-X under the Securities Act of 1933, as amended, to disclose certain information with respect to Sellers and/or the Samedan Group.

(b) From and after Closing until May 31, 2018, Sellers shall (i) cause the appropriate personnel of Sellers, and each of Seller’s Affiliates, and shall request its independent auditors, to reasonably cooperate with Purchaser, to the extent reasonably requested by Purchaser, in the interpretation, preparation and disclosure of any Requested Financial Information and (ii) request Sellers’ independent auditors to (A) provide customary “comfort letters” to any underwriter or purchaser, (B) consent to be named an expert, in any offering memorandum, private placement memorandum or prospectus by Purchaser in which Requested Financial Information is required or customary, and (C) provide access to the work papers of Sellers’ independent auditors related to the Requested Financial Information, but subject to such firm’s policies and procedures relating to such work papers.

Notwithstanding the foregoing, nothing herein shall expand Sellers’ representations, warranties, covenants, or agreements set forth in this Agreement or any other Transaction Document or give Purchaser, its Affiliates, or any Third Party any rights to which such Person is not expressly entitled hereunder.

(d) Purchaser agrees to indemnify, defend and hold harmless each member of the Seller Group from and against any and all Damages (including court costs and reasonable attorneys’ fees) in connection with Sellers’ performance of any obligations or assistance provided under this Section 6.16, including Damages attributable to, arising out of or relating to any Requested Financial Information, books, records, documents, representation letters or other information provided by or on behalf of any member of the Seller Group in connection with this Section 6.16, EVEN IF SUCH CLAIMS, DAMAGES, LIABILITIES, OBLIGATIONS, LOSSES, COSTS, AND EXPENSES ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER SOLE, JOINT, OR CONCURRENT), STRICT LIABILITY, OR OTHER LEGAL FAULT OF ANY MEMBER OF THE SELLER GROUP; provided, however, that the foregoing shall not apply to the willful misconduct or gross negligence of any member of the Seller Group. Notwithstanding anything herein to the contrary, in no event shall Sellers be obligated hereunder to disclose, provide or grant access to any books, records, information or documents to the extent such disclosure, provision or access would, in the reasonable discretion of Sellers, (i) violate applicable Laws, (ii) be likely to result in the waiver any legal privilege of any Seller, any Seller’s Affiliates or Sellers’ counselors, attorneys, accountants or consultants, or (iii) violate any obligations to any Third Party.

(d) Asset Conveyances, duly executed by Purchaser, in sufficient duplicate originals to allow recording in all appropriate jurisdictions and offices;

(h) All other documents and instruments reasonably requested by Sellers from Purchaser that are necessary to transfer the Asset Seller Assets and Subject Securities to Purchaser.

(a) Sellers shall be allocated and bear all Asset Taxes (ignoring, for purposes of this Section 9.1, that such Asset Taxes with respect to the Samedan Assets may be imposed on the Samedan Group rather than on the Parties directly) attributable to (i) any Tax period ending prior to the Effective Time and (ii) the portion of any Straddle Period ending immediately prior to the Effective Time, and Purchaser shall be allocated and bear all Asset Taxes attributable to (x) any Tax period beginning at or after the Effective Time and (y) the portion of any Straddle Period beginning at the Effective Time.

(i) The Parties acknowledge that the State of Colorado and the State of Wyoming determine the assessed value for Property Taxes with respect to certain of the Assets based on the production of Hydrocarbons (“Oil and Gas Property Taxes”). Notwithstanding the forgoing, however, Oil and Gas Property Taxes shall be apportioned between the Parties in accordance with the relative ownership periods during the year such Oil and Gas Property Taxes are assessed. For example, 2017 Oil and Gas Property Taxes for the State of Colorado, payable in 2018, are measured by the value of 2016 production of Hydrocarbons but shall be allocated between Sellers and Purchaser in accordance with their proportionate ownership periods during 2017 before and after the Effective Time (notwithstanding the fact that such Oil and Gas Property Taxes are measured by the value of 2016 production of Hydrocarbons). Similarly, 2017 Oil and Gas Property Taxes for the State of Wyoming, payable in 2018, are measured by the value of 2017 production of Hydrocarbons but shall be allocated between Sellers and Purchaser in accordance with their proportionate ownership periods during 2017 before and after the Effective Time (regardless of the amount of production of Hydrocarbons occurring before and after the Effective Time);

(ii) Property Taxes other than those described in clause (i) (“Other Property Taxes”) shall be deemed attributable to the period during which ownership of the applicable Assets gives rise to liability for such Other Property Taxes, and liability therefor allocated to Sellers for all periods ending prior to the Effective Time and to Purchaser for all periods beginning on or after the Effective Time. Other Property Taxes pertaining to a Straddle Period shall be allocated between the portion of such Straddle Period ending prior to the Effective Time and the portion of such Straddle Period beginning on or after the Effective Time by prorating each such Other Property Tax based on the number of days in the applicable Straddle Period that occur before the day on which the Effective Time occurs, on the one hand, and the number of days in such Straddle Period that occur on and after the day on which the Effective Time occurs, on the other hand. For purposes of the preceding sentence, the period for such Other Property Tax shall begin on the date on which ownership of the applicable Assets gives rise to liability for the particular Other Property Tax and shall end on the day before the next such date; and

(iii) Severance Taxes shall be deemed attributable to the period during which the production of the Hydrocarbons with respect to such Severance Taxes occurred, and liability therefor shall be allocated to Sellers for Severance Taxes that relate to production of Hydrocarbons prior to the Effective Time and to Purchaser for Severance Taxes that relate to production of Hydrocarbons on or after the Effective Time.

(c) To the extent the actual amount of an Asset Tax is not known at the time an adjustment is to be made with respect to such Asset Tax pursuant to Section 2.4 or Section 2.5, as applicable, the Parties shall utilize the most recent information available in estimating the amount of such Asset Tax for purposes of such adjustment. To the extent the actual amount of an Asset Tax (or the amount thereof paid or economically borne by a Party) is ultimately determined to be different than the amount (if any) that was taken into account in the final settlement statement as finally determined pursuant to Section 2.5(b), timely payments will be made from one Party to the other to the extent necessary to cause each Party to bear the amount of such Asset Tax that is allocable to such Party under this Section 9.1.

Section 9.2 Transfer Taxes and Recording Fees. To the extent that any Transfer Taxes are incurred, imposed or payable on the purchase and sale of the Asset Seller Assets or the Subject Securities pursuant to this Agreement, Purchaser shall bear such Transfer Taxes. Purchaser shall pay all required filing and recording fees and expenses in connection with the filing and recording of the Asset Conveyances, assignments and/or other instruments required to convey title to the Assets to Purchaser. Sellers and Purchaser shall reasonably cooperate in good faith to minimize, reduce or eliminate, to the extent permissible under applicable Law, the amount of any such Transfer Taxes.

(a) The Parties shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns and any audit, litigation, or other proceeding with respect to Taxes relating to the Assets. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information that are relevant to any such Tax Return or audit, litigation, or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided under this Agreement. Sellers and Purchaser agree to retain all books and records with respect to Tax matters pertinent to the Assets relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations of the respective taxable periods and to abide by all record retention agreements entered into with any Governmental Authority.

(b) Notwithstanding anything to the contrary in Section 11.6, Sellers shall have the right, at their own expense, to control and settle the portion of any audit, examination, or other administrative or judicial proceeding, contest, assessment, notice of deficiency, or other adjustment or proposed adjustment relating to any and all Taxes for which a Seller may be required to indemnify Purchaser under Section 11.3 (a “Tax Contest”). Purchaser shall have the right to participate at its own expense in any proceeding which Sellers control pursuant to the preceding sentence. Purchaser shall give prompt written notice of any Tax Contest to Sellers and shall execute appropriate powers of attorney so as to allow Sellers to control and settle any such Tax Contest as described above; provided that the failure to provide such notice shall not release Sellers from any indemnification obligation under this Agreement except to the extent that Sellers are actually prejudiced by such failure. If Sellers elect to assume the defense of any Tax Contest, Sellers shall (x) keep Purchaser reasonably informed of all material developments and events relating to such Tax Contest (including promptly forwarding copies to Purchaser of any related correspondence), (y) consult with Purchaser in connection with the defense or prosecution of any such Tax Contest and (z) provide such cooperation and information as Purchaser shall reasonably request.

Section 9.4 Tax Returns. Subject to Purchaser’s indemnification rights under Section 11.3, after the Closing Date, Purchaser shall (a) be responsible for paying any Asset Taxes relating to any Tax period that ends before or includes the Effective Time that become due and payable after the Closing Date and shall file with the appropriate Governmental Authority any and all Tax Returns required to be filed after the Closing Date with respect to such Asset Taxes, (b) submit each such Tax Return to Sellers for their review and comment no fewer than fifteen (15) days prior to the due date therefor, and (c) timely file any such Tax Return, incorporating any comments received from Sellers prior to the due date therefor.

Section 10.1 Termination. This Agreement may be terminated at any time prior to Closing (the date of any permitted termination of this Agreement under this Section 10.1, the “Termination Date”):

(b) by Sellers or Purchaser upon written notice to the other Party, if Closing has not occurred on or before December 1, 2017;

provided, however, that no Party shall be entitled to terminate this Agreement under Section 10.1(b) if (i) the Closing has failed to occur as a result of the breach or failure of any such Party’s representations, warranties, or covenants hereunder, including, if and when required, such Party’s obligations to consummate the transactions contemplated hereunder at Closing or (ii) a Party is entitled to and is enforcing its right to specific performance of this Agreement under Section 10.2(b), Section 10.2(c) or Section 10.2(d).

(a) If this Agreement is terminated pursuant to Section 10.1, this Agreement shall become void and of no further force or effect (except for the provisions of Article 1, Section 2.3, Section 4.12, Section 6.1(b), Section 6.1(c), Section 6.8, Section 6.9, Section 6.11, this Article 10, and Section 12.1 through Section 12.14, all of which shall survive and continue in full force and effect indefinitely). The Confidentiality Agreement shall survive any termination of this Agreement.

(b) In the event that (i) all conditions precedent to the obligations of Sellers set forth in Section 7.1 have been satisfied or waived in writing by Sellers (or would have been satisfied except for the breach or failure of any of Sellers’ representations, warranties or covenants hereunder) and (ii) the Closing has not occurred solely as a result of the material breach or material failure of Sellers’ representations, warranties or covenants hereunder, including, if and when required, Sellers’ obligations to consummate the transactions contemplated hereunder at Closing, then Purchaser shall, at Purchaser’s option, be entitled to (1) terminate this Agreement and receive the Deposit (and all interest having accrued thereon), free and clear of any claims thereof by Sellers or (2) exercise any rights at law or in equity to enforce the specific performance of this Agreement.

(c) In the event that (i) all conditions precedent to the obligations of Purchaser set forth in Section 7.2 have been satisfied or waived in writing by Purchaser (or would have been satisfied except for the breach or failure of any of Purchaser’s representations, warranties or covenants hereunder) and (ii) the Closing has not occurred solely as a result of the material breach or material failure of Purchaser’s representations, warranties or covenants hereunder,

including, if and when required, Purchaser’s obligations to consummate the transactions contemplated hereunder at Closing, then Sellers shall, at Sellers’ option, be entitled to (1) terminate this Agreement and retain the entirety of the Deposit for the sole account and use of Sellers as liquidated damages hereunder or (2) exercise any rights at law or in equity and the rights of specific performance of this Agreement. Sellers and Purchaser acknowledge and agree that in the event Sellers elect to terminate and retain the Deposit (x) Sellers’ actual damages upon the event of such a termination are difficult to ascertain with any certainty, (y) the Deposit is a fair and reasonable estimate by the Parties of such aggregate actual damages of Sellers, and (z) such liquidated damages do not constitute a penalty.

(d) In the event that this Agreement is terminated and Purchaser does not exercise its rights in Section 10.2(b)(2) and Sellers are not entitled or required to retain the Deposit under Section 10.2(c), Purchaser shall be entitled to receive the entirety of the Deposit from Sellers for the account of Purchaser.

(e) Each Party acknowledges that as express consideration for the Parties entering into this Agreement and such Party’s representations, warranties and covenants set forth herein, each Party covenants and agrees that solely with respect to each Party’s rights to exercise any rights at law or in equity and the rights of specific performance, (i) such Party would be irreparably harmed by any breaches by the other Party of its obligations to consummate the transactions hereunder as and when required by such Party hereunder, (ii) monetary damages would not be a sufficient remedy for any violation of the terms of this Agreement, (iii) such Party shall be entitled to equitable relief, including injunction (without the posting of any bond and without proof of actual damages) and specific performance, in the event of any breach of the provisions of this Agreement with respect to such Party’s rights under Section 10.2, and (iv) neither the other Party, nor its representatives shall oppose the granting of specific performance or any such relief as a remedy.

Section 11.1 Assumption and Retention. Without limiting Purchaser’s rights to indemnity under this Article 11, from and after the Closing Date, Purchaser assumes and hereby agrees to fulfill, perform, pay, and discharge (or cause to be fulfilled, performed, paid, or discharged) all of the obligations, liabilities, and Damages, known or unknown, with respect to the ownership, use, and operation of the Asset Seller Assets and Subject Securities, regardless of whether such obligations or liabilities arise out of, are attributable to, or incurred prior to, on, or after the Effective Time or the Closing Date (the “Assumed Obligations”); provided, that notwithstanding the foregoing, from and after the Closing, Sellers shall retain and hereby agree to fulfill, perform, pay and discharge (or cause to be fulfilled, performed, paid or discharged) the Retained Liabilities.

Section 11.2 Sellers’ Indemnification Rights. Subject to the terms hereof, from and after the Closing Date, Purchaser shall be responsible for, shall pay, and shall indemnify, defend, and hold harmless each Seller, each Affiliate of such Seller, and each of such Person’s respective shareholders, members, officers, directors, employees, agents, lenders, advisors, representatives, accountants, attorneys, and consultants (“Seller Group”) from and against all obligations, liabilities, claims, causes of action, and Damages caused by, arising out of, attributable to, or resulting from:

(a) any failure or breach of any of Purchaser’s covenants or agreements contained in this Agreement or in any Transaction Document;

(b) any failure or breach of any representation or warranty made by Purchaser contained in Article 4 of this Agreement, in the certificate delivered by Purchaser at Closing pursuant to Section 8.3(g) or in any Transaction Document; and/or

EVEN IF ANY SUCH DAMAGES ARE CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER GROSS, SOLE, JOINT, ACTIVE, PASSIVE, COMPARATIVE, OR CONCURRENT), STRICT LIABILITY, OR OTHER LEGAL FAULT OF ANY INDEMNIFIED PERSON, INVITEE, OR THIRD PARTY, but excepting and excluding in the case of Section 11.2(a), Section 11.2(b) and Section 11.2(c), any Damages against which Purchaser is entitled to indemnity from any Seller under Section 11.3 at the time the applicable Claim Notice is presented by Purchaser (but such exception and exclusion only applying to the extent and for the periods Sellers are obligated hereunder to provide such indemnity under this Article 11).

Section 11.3 Purchaser’s Indemnification Rights. Subject to the terms hereof, from and after the Closing Date, Sellers shall be responsible for, shall pay, and shall indemnify, defend, and hold harmless Purchaser, the Affiliates of Purchaser, and each of their respective shareholders, members, officers, directors, employees, agents, advisors, representatives, accountants, attorneys, and consultants (“Purchaser Group”) against and from all obligations, liabilities, claims, causes of action, and Damages that are caused by, arising out of, attributable to, or resulting from:

(a) any failure or breach of any Seller’s covenants or agreements contained in this Agreement;

(b) any failure or breach of any representation or warranty made by any Seller contained in Article 3 of this Agreement or in the certificate delivered by Sellers at Closing pursuant to Section 8.2(g); and/or

(a) Subject to Section 11.4(b) and Section 11.4(c): (i) the Non-Fundamental Representations of Sellers (other than the Special Warranties, which shall survive until four (4) years after the Closing Date) shall survive Closing and terminate on the date twelve (12) months after the Closing Date; (ii) the Fundamental Representations in Section 3.4(b) shall survive the Closing indefinitely and all other Fundamental Representations shall survive the Closing and terminate on the expiration of the applicable statute of limitation; (iii) the covenants and

agreements of Sellers to be performed on or prior to Closing shall each survive the Closing and terminate on the date six (6) months after the Closing Date; (iv) the covenants and agreements of Sellers to be performed after Closing shall survive the Closing and terminate on the date twenty-four (24) months after the Closing Date; provided, the covenants and agreements of Sellers contained in Section 2.6, Section 6.3, Section 9.1 shall survive the Closing and terminate on the expiration of the applicable statute of limitations; (v) the indemnification or reimbursement rights of the Purchaser Group in Section 11.3 shall survive the Closing and terminate on the termination date of each respective representation, warranty, covenant, or agreement of Sellers that is subject to indemnification thereunder; (vi) the covenants, representations, and warranties of Purchaser set forth in this Agreement and the other Transaction Documents shall survive the Closing indefinitely, and (vii) the representations, warranties, covenants, and agreements of Sellers set forth in this Agreement and the other Transaction Documents shall be of no further force and effect, and Sellers shall not have any obligations hereunder, after the applicable date of their expiration; provided, however, there shall be no expiration or termination of any bona fide claim validly asserted pursuant to a valid Claim Notice pursuant to this Agreement with respect to such a representation, warranty, covenant, or agreement prior to the expiration or termination date of the applicable survival period thereof.

(b) As a condition to making any claims for indemnification, defense, or to be held harmless under this Article 11, Purchaser must deliver a valid Claim Notice pursuant to this Agreement prior to the expiration or termination date of the applicable survival period (if any) thereof or the date otherwise required to be delivered hereunder. All rights of each member of the Purchaser Group to indemnification and reimbursement under Section 11.3(b) with respect to Non-Fundamental Representations and under Section 11.3(a) with respect to the covenants and agreements of Seller to be performed on or prior to Closing shall terminate and expire on the earlier to occur of (i) the termination date of each respective representation or warranty of Sellers for which Purchaser is entitled to indemnification or reimbursement hereunder, except in each case as to matters for which a specific written Claim Notice has been validly delivered to Sellers on or before the earlier of such termination date or the date otherwise required to be delivered hereunder or (ii) the date the Purchaser Group has received indemnification and/or reimbursement from Sellers in an aggregate amount equal to the amount set forth in Section 11.4(c). All rights of each member of the Purchaser Group to indemnification under Section 11.3(b) with respect to Fundamental Representations not contained in Section 3.4(b) or Section 3.19 and Section 11.3(a) with respect to the covenants and agreements of Sellers to be performed after the Closing Date shall survive the Closing and terminate on the earlier to occur of (A) (w) with respect to Section 3.19, four (4) years after the Closing Date, (x) with respect to the other Fundamental Representations, the expiration of the applicable statute of limitations and (y) with respect to the covenants and agreements of Sellers be performed after Closing, other than those contained in Section 2.6, Section 6.3, Section 9.1, twenty-four (24) months after the Closing Date (B) the date the Purchaser Group has received indemnification and/or reimbursement from Sellers in an aggregate amount equal to the amounts set forth in Section 11.4(c).

(c) Subject to Section 5.2 and Section 12.11 and notwithstanding anything to the contrary contained elsewhere in this Agreement, Sellers shall not have any liability or be required to indemnify Purchaser (i) under Section 11.3(b) with respect to Non-Fundamental Representations (other than the Special Warranties) Damages relating to or arising out of any

individual event, matter or occurrence for which a Claim Notice is delivered by Purchaser and for which Sellers admit (or it is otherwise finally determined) that Sellers have an obligation to indemnify Purchaser pursuant to Section 11.3(b) unless and until the amount of such Damages exceeds the Indemnity Threshold (it being agreed that the Indemnity Threshold represents a threshold and not a deductible), (ii) under Section 11.3(b) with respect to Non-Fundamental Representations (other than the Special Warranties) for Damages that exceed the Indemnity Threshold for which Claim Notices are delivered by Purchaser and for which Sellers admit (or it is otherwise finally determined) that Sellers have an obligation to indemnify Purchaser pursuant to Section 11.3(b) unless the aggregate amount of all such Damages exceeds two percent (2%) of the Unadjusted Purchase Price and then only to the extent such liability exceeds two percent (2%) of the Unadjusted Purchase Price (it being agreed that such amount represents a deductible and not a threshold), (iii) under Section 11.3(b) for aggregate Damages in excess of ten percent (10%) of the Unadjusted Purchase Price relating to breaches of Non-Fundamental Representations (other than the Special Warranties) and (iv) under this Agreement or any of the agreements, instruments, or documents delivered in connection with the transactions contemplated hereunder for aggregate Damages in excess of one hundred percent (100%) of the Unadjusted Purchase Price. Subject to Section 12.11, the liability of Purchaser pursuant to Section 11.2 shall be without limit.

(d) No Party or Person is asserting the accuracy, completeness, or truth of any representation and warranty set forth in this Agreement; rather the Parties have agreed that should any representation or warranty of any Party prove inaccurate, incomplete or untrue, the other Party shall have the specific rights and remedies herein specified as the exclusive remedy therefor, but that no other rights, remedies or causes of action (whether in law or in equity or whether in contract or in tort or otherwise) are permitted to any Party as a result of the failure, breach, inaccuracy, incompleteness or untruth of any such representation and warranty. Sellers and Purchaser each acknowledge and agree that (i) the payment of money, as limited by the terms of this Agreement, shall be adequate compensation for breach of any representation, warranty, covenant, or agreement contained herein or for any other claim arising in connection with or with respect to the transactions contemplated by this Agreement and (ii) Purchaser and Sellers hereby waive any and all rights to rescind, reform, cancel, terminate, revoke, or void this Agreement or any of the transactions contemplated hereby; provided, however, Sellers shall have the right to specific performance and other equitable remedies available at law or equity (including injunctive relief) for the breach or failure of Purchaser to perform its obligations required to be performed after Closing.

(e) Sellers shall not be required to indemnify Purchaser under Section 11.3(b) for any Asset Tax (or portion thereof) allocable to Purchaser under Section 9.1 as a result of a breach by Seller of any representation or warranty set forth in Section 3.12 or Section 3.13, except to the extent the amount of such Asset Tax (or portion thereof) exceeds the amount that would have been due absent such breach.

(a) Notwithstanding anything to the contrary contained in this Agreement, from and after Closing, Purchaser’s and Purchaser Group’s sole exclusive remedy against any member of the Seller Group with respect to the negotiation, performance, and consummation of

the transactions contemplated hereunder, any breach of the representations, warranties, covenants, and agreements of any member of the Seller Group contained herein, the affirmations of such representations, warranties, covenants, and agreements contained in the certificates delivered by any member of the Seller Group at Closing pursuant to Section 8.2(g) or contained in any other Transaction Document delivered hereunder by or on behalf of any member of the Seller Group are the rights set forth in Section 11.3, as limited by the terms of this Article 11. Except for the remedies contained in this Article 11, upon Closing, Purchaser waives, releases, remises, and forever discharges, and shall cause each member of the Purchaser Group to waive, release, remise, and forever discharge, each member of the Seller Group from any and all Damages, suits, legal or administrative proceedings, claims, demands, losses, costs, obligations, liabilities, interest, charges, or causes of action whatsoever, in law or in equity, known or unknown, which any member of the Purchaser Group might now or subsequently may have, based on, relating to, or arising out of the negotiation, performance, and consummation of this Agreement or the transactions contemplated hereunder or any member of the Seller Group’s ownership, use or operation of the Assets and Subject Securities, or the condition, quality, status, or nature of the Assets or Subject Securities, INCLUDING RIGHTS TO CONTRIBUTION UNDER CERCLA OR ANY OTHER ENVIRONMENTAL LAW, BREACHES OF STATUTORY AND IMPLIED WARRANTIES, NUISANCE OR OTHER TORT ACTIONS, RIGHTS TO PUNITIVE DAMAGES, COMMON LAW RIGHTS OF CONTRIBUTION, ANY RIGHTS UNDER INSURANCE POLICIES ISSUED OR UNDERWRITTEN BY ANY MEMBER OF THE PURCHASER GROUP, AND ANY RIGHTS UNDER AGREEMENTS AMONG ANY MEMBERS OF THE SELLER GROUP, EVEN IF CAUSED IN WHOLE OR IN PART BY THE NEGLIGENCE (WHETHER GROSS, SOLE, JOINT, ACTIVE, PASSIVE, COMPARATIVE, OR CONCURRENT), STRICT LIABILITY OR OTHER LEGAL FAULT OF ANY RELEASED PERSON, INVITEE, OR THIRD PARTY. Without limiting the generality of the immediately preceding sentence, Purchaser agrees, and shall cause each member of the Purchaser Group to agree, that from and after Closing the sole and exclusive remedies of the Purchaser Group with respect to any member of the Seller Group’s breach of representations, warranties, covenants, and agreements herein or in the other Transaction Document shall be the rights to indemnity under Section 11.3, as limited by the terms of this Article 11. No Party or Person is asserting the accuracy, completeness, or truth of any representation and warranty set forth in this Agreement; rather the Parties have agreed that should any representation or warranty of any Party prove inaccurate, incomplete, or untrue, the other Party shall have the specific rights and remedies herein specified as the exclusive remedy therefor, but that no other rights, remedies, or causes of action (whether in law or in equity or whether in contract or in tort or otherwise) are permitted to any Party hereto as a result of the failure, breach, inaccuracy, incompleteness, or untruth of any such representation and warranty.

(b) Any claim for indemnity under this Article 11 by any current or former Affiliate, stockholder, member, officer, director, employee, agent, lender, advisor, representative, accountant, attorney, and consultant of any Party must be brought and administered by the applicable Party to this Agreement. No Indemnified Person other than Sellers and Purchaser shall have any rights against Sellers or Purchaser under the terms of this Article 11 except as may be exercised on its behalf by Purchaser or Sellers, as applicable, pursuant to this Article 11. Sellers and Purchaser may elect to exercise or not exercise indemnification rights under this Section on behalf of the other Indemnified Persons affiliated with it in its sole discretion and shall have no liability to any such other Indemnified Person for any action or inaction under this Section.

(c) Notwithstanding anything in this Agreement to the contrary, if the Closing occurs, in no event shall any member of the Purchaser Group be entitled to assert the breach or failure of any representation, warranty, or covenant of any member of the Seller Group or any condition precedent of Purchaser in this Agreement or any related document or any certificate delivered pursuant hereto or thereto as a basis for a claim for indemnification or defense under this Article 11 to the extent that any member of the Purchaser Group had knowledge of such breach or failure prior to the Closing Date, and the members of the Purchaser Group shall be deemed to have waived any claim for breach of a covenant, representation, or warranty or for indemnity hereunder related thereto.

(d) The amount of any Damages for which Purchaser or any member of the Purchaser Group is entitled to indemnity under this Article 11 shall be reduced by the amount of insurance or other Third Party proceeds, reimbursements, or claims realized or that could reasonably be expected to be realized by Purchaser or applicable members of the Purchaser Group if a claim were properly pursued under the relevant insurance arrangements with respect to such Damages. Purchaser shall use commercially reasonable efforts to pursue and prosecute any and all claims against Third Parties for which Purchaser or any member of the Purchaser Group is entitled to indemnity from Sellers under this Article 11. In the event that any member of the Purchaser Group receives funds or proceeds from any insurance carrier or any other Third Party with respect to any Damages, Purchaser shall, regardless of when received by such member of the Purchaser Group, promptly pay to the Sellers such funds or proceeds to the extent of any funds previously paid by Sellers or any of its Affiliates with respect to such Damages.

(e) Subject to the terms hereof, each Indemnified Person shall use commercially reasonable efforts to mitigate or minimize all Damages upon and after becoming aware of any event or condition which would reasonably be expected to give rise to any Damages that are indemnifiable hereunder. If an Indemnified Person fails to so mitigate any indemnifiable Damages under the preceding sentence, such Indemnified Person shall have no right to indemnity hereunder with respect to such Damages and the Indemnifying Party shall have no liability for any portion of such Damages that reasonably could have been avoided, reduced, or mitigated had the Indemnified Person made such reasonable efforts.

(f) The Parties shall treat, for U.S. federal and applicable state and local income tax purposes, any amounts paid or received under this Article 11 as an adjustment to the Adjusted Purchase Price, unless otherwise required by applicable Laws.

(g) To the extent of the indemnification obligations in this Agreement, Purchaser and Sellers hereby waive for themselves and their respective successors and assigns, including any insurers, any rights to subrogation for Damages for which such Party is liable or against which such Party indemnifies any other Person under this Agreement. If required by applicable insurance policies, each Party shall obtain a waiver of such subrogation from its insurers.

(h) Notwithstanding anything herein or in any Transaction Document to the contrary, the obligations and the rights of the Parties hereunder, and the amount of any Damages for which any Party is obligated to indemnify, or any member of the Seller Group or any member of the Purchaser Group, as applicable, is entitled to indemnity under Section 11.2 or Section 11.3 as applicable, shall be calculated by excluding and without giving effect to any qualifiers as to materiality or Material Adverse Effect set forth in any representation or warranty of Sellers or Purchaser; provided, however, this subpart (h) shall not apply in connection with the determination of any breaches of any such representations or warranties.

Section 11.6 Indemnification Actions. All claims for indemnification under Article 11 shall be asserted and resolved as follows:

(a) For purposes of this Article 11, the term “Indemnifying Party” when used in connection with particular Damages means (i) Sellers in the event any member of the Purchaser Group is entitled to indemnity from Sellers under Section 11.3 and (ii) Purchaser in the event any member of the Seller Group is entitled to indemnification under this Agreement. For purposes of this Article 11, the term “Indemnified Person” when used in connection with particular Damages means (A) Purchaser in the event any member of the Purchaser Group is entitled to indemnity from Sellers under Section 11.3 and (B) Sellers in the event any member of the Seller Group is entitled to indemnification under this Agreement.

(b) To make a claim for indemnification, defense, or reimbursement under this Article 11, an Indemnified Person shall notify the Indemnifying Party of its claim, including the specific details (including supporting documentation of the alleged Damages in such Indemnified Person’s possession and control and such Indemnified Person’s good faith estimate of the applicable claim) of and specific basis under this Agreement for its claim (the “Claim Notice”).

(c) In the event that any claim for indemnification set forth in any Claim Notice is based upon a claim by a Third Party against the Indemnified Person (a “Third Party Claim”), the Indemnified Person shall provide its Claim Notice promptly after the Indemnified Person has actual knowledge of the Third Party Claim and shall enclose a copy of all papers (if any) served with respect to the Third Party Claim in such Indemnified Person’s possession and control; provided that the failure of any Indemnified Person to give notice of any Third Party Claim as provided in this Section 11.6 shall not relieve the Indemnifying Party of its obligations under this Article 11 except to the extent such failure results in insufficient time being available to permit the Indemnifying Party to effectively defend against the Third Party Claim or otherwise prejudices the Indemnifying Party’s ability to defend against the Third Party Claim. In the event that the claim for indemnification is based upon an alleged inaccuracy or breach of a representation, warranty, covenant, or agreement, the Claim Notice shall specify the representation, warranty, covenant, or agreement that was allegedly inaccurate or breached.

(d) In the case of a claim for indemnification based upon any Third Party Claim, the Indemnifying Party shall have thirty (30) days from its receipt of the Claim Notice to notify the Indemnified Person whether it admits or denies (i) in the case of Sellers, Purchaser’s right to indemnity from Sellers in respect of such Third Party Claim as provided in this Article 11 or (ii) in the case of Purchaser, its obligation to defend the Indemnified Person against

such Third Party Claim under this Article 11. The Indemnified Person is authorized, prior to and during such thirty (30) day period, to file any motion, answer, or other pleading that it shall deem necessary or appropriate to protect its interests or those of the Indemnifying Party and that is not prejudicial to the Indemnifying Party. If the Indemnifying Party fails to notify the Indemnified Person within such thirty (30) day period regarding whether the Indemnifying Party admits or denies (A) in the case of Sellers, Purchaser’s right to indemnity from Sellers in respect of such Third Party Claim as provided in this Article 11 or (B) in the case of Purchaser, its obligation to defend the Indemnified Person against such Third Party Claim under this Article 11, then until such date as the Indemnifying Party admits or it is finally determined by a non-appealable judgment that such right or obligation exists, the Indemnified Person may file any motion, answer, or other pleading, settle any Third Party Claim or take any other action that the Indemnified Person deems necessary or appropriate to protect its interest, regardless of whether the Indemnifying Party is prejudiced or adversely impacted by any such actions.

(e) If (i) Sellers admit Purchaser’s right to indemnity from Sellers in respect of such Third Party Claim as provided in this Article 11 or (ii) Purchaser admits its obligation to defend the Indemnified Person against such Third Party Claim under this Article 11, as applicable, then the applicable Indemnifying Party shall have (x) the right and obligation to diligently prosecute and control the defense of such Third Party Claim, if Purchaser is the Indemnifying Party, at the sole cost and expense of Purchaser, and if Sellers are the Indemnifying Party, at the sole cost and expense of Sellers, and (y) full control of such defense and proceedings, including any compromise or settlement thereof unless the compromise or settlement includes the payment of any amount by, the performance of any obligation by, or the limitation of any right or benefit of, the Indemnifying Party, in which event such settlement or compromise shall not be effective without the consent of the Indemnified Person, which shall not be unreasonably withheld or delayed. If requested by the Indemnifying Party, the Indemnified Person agrees at the cost and expense of the Indemnifying Party to cooperate in contesting any Third Party Claim which the Indemnifying Party elects to contest; provided, however, that the Indemnified Person shall not be required to bring any counterclaim or cross-complaint against any Person. The Indemnified Person may participate in, but not control, any defense or settlement of any Third Party Claim controlled by the Indemnifying Party pursuant to this Section 11.6(e), provided that the Indemnified Person may file initial pleadings as described in the last sentence of Section 11.6(d) if required by court or procedural rules to do so within the thirty (30) day period in Section 11.6(d). An Indemnifying Party shall not, without the written consent of the Indemnified Person, settle any Third Party Claim or consent to the entry of any judgment with respect thereto that (A) does not result in a final resolution of the Indemnified Person’s liability with respect to the Third Party Claim (including, in the case of a settlement, an unconditional written release of the Indemnified Person from all further liability in respect of such Third Party Claim) or (B) may materially and adversely affect the Indemnified Person (other than as a result of money damages covered by the indemnity).

(f) If (i) Sellers do not admit Purchaser’s right to indemnity from Sellers in respect of such Third Party Claim as provided in this Article 11 or admit such right but thereafter fail to diligently defend or settle the Third Party Claim or (ii) Purchaser admits its obligation to defend the Indemnified Person against such Third Party Claim under this Article 11 or admits its obligation but thereafter fails to diligently defend or settle the Third Party Claim, as applicable, then the Indemnified Person shall have the right, but not the obligation, to defend and control the

defense against the Third Party Claim (if Purchaser is the Indemnifying Party, at the sole cost and expense of Purchaser, and if Sellers are the Indemnifying Party, at the sole cost and expense of Sellers, and in either case if the Indemnified Person is entitled to indemnification hereunder), with counsel of the Indemnified Person’s choosing, subject to the right of (x) Sellers as the Indemnifying Party to admit Purchaser’s right to indemnity from Sellers in respect of such Third Party Claim as provided in this Article 11 or (y) Purchaser as the Indemnifying Party to admit its obligation to defend the Indemnified Person against such Third Party Claim under this Article 11, as applicable, at any time prior to settlement or final determination thereof. If (A) Sellers have not yet admitted Purchaser’s right to indemnity from Sellers in respect of such Third Party Claim as provided in this Article 11 or (B) Purchaser has not yet admitted its obligation to defend the Indemnified Person against such Third Party Claim under this Article 11, as applicable, the Indemnified Person shall send written notice to the Indemnifying Party of any proposed settlement and the Indemnifying Party shall have the option for ten (10) days following receipt of such notice to (i)(1) in the case of Sellers, admit Purchaser’s right to indemnity from Sellers in respect of such Third Party Claim as provided in this Article 11 or (2) in the case of Purchaser, admit its obligation to defend the Indemnified Person against such Third Party Claim under this Article 11, as applicable, and (ii) if such right or obligation is so admitted, assume the defense of the Third Party Claim, including the power to reject the proposed settlement. If the Indemnified Person settles any Third Party Claim over the objection of the Indemnifying Party after the Indemnifying Party has timely admitted such right or obligation for indemnification in writing and assumed the defense of the Third Party Claim, the Indemnified Person shall be deemed to have waived any right to indemnity with respect to the Third Party Claim.

(g) In the case of a claim for indemnification not based upon an Third Party Claim (a “Direct Claim”), such Direct Claim shall be asserted by giving the Indemnifying Party a reasonably prompt Claim Notice thereof, but in any event not later than thirty (30) days after the Indemnified Person becomes aware of the events that gave rise to such Direct Claim. Such Claim Notice by the Indemnified Person shall describe the Direct Claim in reasonable detail, shall include copies of all available material written evidence in such Indemnified Person’s possession or control thereof and shall indicate the estimated amount, if reasonably practicable, of Damages that have been or may be sustained by the Indemnified Person. The Indemnifying Party shall have sixty (60) days from its receipt of the Claim Notice to (i) cure the Damages complained of, (ii)(x) in the case of Sellers, admit Purchaser’s right to indemnity from Sellers in respect of such Direct Claim as provided in this Article 11 or (y) in the case of Purchaser, admits its obligation to defend the Indemnified Person against such Direct Claim under this Article 11, as applicable, or (iii) dispute the claim for such Damages. If the Indemnifying Party does not notify the Indemnified Person within such sixty (60) day period that it has cured the Damages or that it disputes the claim for such Damages, the Indemnifying Party shall be conclusively deemed (1) in the case of Sellers, to have admitted Purchaser’s right to indemnity from Sellers in respect of such Direct Claim as provided in this Article 11 or (2) in the case of Purchaser, to have admitted its obligation to defend the Indemnified Person against such Direct Claim under this Article 11, as applicable.

Section 11.7 Express Negligence/Conspicuous Manner. WITH RESPECT TO THIS AGREEMENT, BOTH PARTIES AGREE THAT THE PROVISIONS SET OUT IN THIS ARTICLE 11 AND ELSEWHERE IN THIS AGREEMENT COMPLY WITH THE REQUIREMENT, KNOWN AS THE EXPRESS NEGLIGENCE RULE, TO EXPRESSLY

STATE IN A CONSPICUOUS MANNER TO AFFORD FAIR AND ADEQUATE NOTICE THAT THIS AGREEMENT HAS PROVISIONS REQUIRING PURCHASER TO BE RESPONSIBLE FOR THE NEGLIGENCE (WHETHER GROSS, SOLE, JOINT, ACTIVE, PASSIVE, COMPARATIVE, OR CONCURRENT), STRICT LIABILITY, OR OTHER FAULT OF MEMBERS OF THE SELLER GROUP AND PURCHASER GROUP. PURCHASER REPRESENTS TO SELLER GROUP (A) THAT PURCHASER HAS CONSULTED AN ATTORNEY CONCERNING THIS AGREEMENT OR, IF IT HAS NOT CONSULTED AN ATTORNEY, THAT PURCHASER WAS PROVIDED THE OPPORTUNITY AND HAD THE ABILITY TO SO CONSULT, BUT MADE AN INFORMED DECISION NOT TO DO SO AND (B) THAT PURCHASER FULLY UNDERSTANDS ITS OBLIGATIONS UNDER THIS AGREEMENT.

Section 12.1 Notices. Any notice, request, instruction, correspondence, or other document to be given hereunder by any Party to another (herein collectively called “Notice”) shall be in writing and delivered in person or by courier service requiring acknowledgement of receipt or mailed by certified mail, postage prepaid and return receipt requested, facsimile transmission or other e-mail transmission following appropriate confirmation of receipt by return e-mail, including an automated confirmation of receipt, as follows:

Notice given by personal delivery or courier shall be effective upon actual receipt. Notice given by mail shall be effective upon actual receipt. Any Party may change any address to which Notice is to be given to it by giving Notice as provided above of such change of address.

Section 12.2 Governing Law. This Agreement and the documents delivered pursuant hereto and the legal relations between the Parties shall be governed by, construed, and enforced in accordance with the Laws of the State of Texas, without regard to principles of conflicts of Laws that would direct the application of the Laws of another jurisdiction; provided, however, with respect to conveyancing matters as to any Mineral Interest or Surface Interest, the Laws of the state where such Mineral Interest or Surface Interest is located shall control.

(a) Except as to any dispute, controversy, matters, or claim arising out of or in relation to or in connection with the calculation or determination of the Adjusted Purchase Price pursuant to Section 2.4, Section 2.4, Section 2.6 or Section 2.7 (which shall be resolved exclusively in accordance with Section 2.5(b)), or the scope, interpretation, and effect of this Article 12, any dispute, controversy, matter or claim between the Parties (each, subject to such exceptions, a “Dispute”), that cannot be resolved among the Parties, will be instituted exclusively in the courts of the State of Texas in and for Harris County or the United States District Court or the Texas State District Court located in Houston, Texas and each Party hereby irrevocably consents to the exclusive jurisdiction in connection with any Dispute, litigation or proceeding arising out of this Agreement or any of the transactions contemplated thereby. All Disputes between the Parties to this Agreement and the transactions contemplated hereby shall have exclusive jurisdiction and venue only in the courts of the State of Texas in and for Harris County or the United States District Court or the Texas State District Court located in Houston, Texas. Each Party waives any objection which it may have pertaining to improper venue or forum non-conveniens to the conduct of any litigation or proceeding in the foregoing courts. Each Party agrees that any and all process directed to it in any such proceeding or litigation may be served upon it outside of the State of Texas with the same force and effect as if such service had been made within the State of Texas in and for Harris County or the United States District Court or the Texas State District Court located in Houston, Texas.

(b) EACH OF THE PARTIES HEREBY VOLUNTARILY AND IRREVOCABLY WAIVES TRIAL BY JURY IN ANY LITIGATION, ACTION OR OTHER PROCEEDING BROUGHT IN CONNECTION WITH THIS AGREEMENT.

Section 12.4 Headings and Construction. The headings and captions herein are inserted for convenience of reference only and are not intended to govern, limit, or aid in the construction of any term or provision hereof. The rights and obligations of each Party shall be determined pursuant to this Agreement. Sellers and Purchaser have each had the opportunity to

exercise business discretion in relation to the negotiation of the details and terms of the transaction contemplated hereby. This Agreement is the result of arm’s length negotiations from equal bargaining positions. It is the intention of the Parties that every covenant, term, and provision of this Agreement shall be construed simply according to its fair meaning and not strictly for or against any Party (notwithstanding any rule of law requiring an agreement to be strictly construed against the drafting Party), and no consideration shall be given or presumption made, on the basis of who drafted this Agreement or any particular provision thereof, it being understood that the Parties to this Agreement are sophisticated and have had adequate opportunity and means to exercise business discretion in relation to the negotiation of the details of the transaction contemplated hereby and to retain counsel to represent their interests and to otherwise negotiate the provisions of this Agreement.

Section 12.5 Waivers. Any failure by any Party to comply with any of its obligations, agreements, or conditions herein contained may be waived by the Party to whom such compliance is owed by the application of the express terms hereof by an instrument signed by the Party to whom compliance is owed and expressly identified as a waiver, but not in any other manner. No course of dealing on the part of any Party or its respective officers, employees, agents, or representatives and no failure by any Party to exercise any of its rights under this Agreement shall, in each case, operate as a waiver thereof or affect in any way the right of such Party at a later time to enforce the performance of such provision. Except as otherwise expressly provided herein, no waiver of, or consent to a change in or modification of, any of the provisions of this Agreement shall be deemed or shall constitute a waiver of, or consent to a change in or modification of, other provisions hereof (whether or not similar), nor shall such waiver constitute a continuing waiver unless otherwise expressly provided herein. The rights of each Party under this Agreement shall be cumulative and the exercise or partial exercise of any such right shall not preclude the exercise by such Party of any other right.

Section 12.6 Severability. It is the intent of the Parties that the provisions contained in this Agreement shall be severable and should any terms or provisions, in whole or in part, be held invalid, illegal, or incapable of being enforced as a matter of law, such holding shall not affect the other portions of this Agreement, and such portions that are not invalid shall be given effect without the invalid portion. Upon such determination that any term or provision is invalid, illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the extent possible.

Section 12.7 Assignment. No Party shall assign or otherwise transfer all or any part of this Agreement, nor shall any Party delegate any of its rights or duties hereunder, without the prior written consent of the other Party and any transfer or delegation made without such consent shall be null and void. Unless expressly agreed to in writing by the Parties, no permitted assignment of any Party’s rights or duties that is subject to the consent of the other Party shall relieve or release the assigning Party from the performance of such Party’s rights or obligations hereunder and such assigning Party shall be fully liable to the other Party for the performance of all such rights and duties. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the Parties hereto and their respective permitted successors and assigns.

Section 12.8 Entire Agreement. This Agreement, the exhibits and schedules attached hereto and the other Transaction Documents constitute the entire agreement among the Parties pertaining to the subject matter hereof, and supersede all prior agreements, understandings, negotiations, and discussions, whether oral or written, of the Parties pertaining to the subject matter hereof. IN THE EVENT OF A CONFLICT BETWEEN THE TERMS AND PROVISIONS OF THIS AGREEMENT AND THE TERMS AND PROVISIONS OF ANY SCHEDULE OR EXHIBIT HERETO, THE TERMS AND PROVISIONS OF THIS AGREEMENT SHALL GOVERN AND CONTROL; PROVIDED, HOWEVER THAT THE INCLUSION IN ANY OF THE SCHEDULES AND EXHIBITS HERETO OF TERMS AND PROVISIONS NOT ADDRESSED IN THIS AGREEMENT SHALL NOT BE DEEMED A CONFLICT, AND ALL SUCH ADDITIONAL PROVISIONS SHALL BE GIVEN FULL FORCE AND EFFECT, SUBJECT TO THE PROVISIONS OF THIS SECTION 12.8.

Section 12.9 Amendment. This Agreement may be amended or modified only by an agreement in writing signed by Purchaser and each Seller and expressly identified as an amendment or modification.

Section 12.10 No Third-Person Beneficiaries. Nothing in this Agreement shall entitle any Person other than Purchaser and Sellers to any claim, cause of action, remedy, or right of any kind, except the rights expressly provided to the Persons described in Section 6.3, Section 6.7, and Section 11.5(b), in each case, only to the extent such rights are exercised or pursued, if at all, by Sellers or Purchaser acting on behalf of such Person (which rights may be exercised in the sole discretion of the applicable Party hereunder). Notwithstanding the foregoing: (a) the Parties reserve the right to amend, modify, terminate, supplement, or waive any provision of this Agreement or this entire Agreement without the consent or approval of any other Person (including any Indemnified Person) and (b) no Party hereunder shall have any direct liability to any permitted Third Party beneficiary, nor shall any permitted Third Party beneficiary have any right to exercise any rights hereunder for such Third Party beneficiary’s benefit except to the extent such rights are brought, exercised, and administered by a Party or its successors and permitted assigns hereto in accordance with Section 11.5(b).

Section 12.11 Limitation on Damages. Notwithstanding anything to the contrary contained herein, NO PERSON SHALL BE ENTITLED TO LOST PROFITS, INDIRECT, CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY AND EACH OF PURCHASER AND SELLERS, FOR ITSELF AND ON BEHALF OF THEIR RESPECTIVE MEMBERS OF THE PURCHASER GROUP AND SELLER GROUP, RESPECTIVELY, HEREBY EXPRESSLY WAIVES ANY RIGHT TO LOST PROFITS, INDIRECT, CONSEQUENTIAL, SPECIAL, OR PUNITIVE DAMAGES IN CONNECTION WITH THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY, OTHER THAN LOSS OF PROFITS, CONSEQUENTIAL DAMAGES, OR PUNITIVE DAMAGES SUFFERED BY ANY THIRD PARTY FOR WHICH RESPONSIBILITY IS ALLOCATED AMONG THE PARTIES UNDER THE TERMS HEREOF.

Section 12.12 Deceptive Trade Practices Act. Purchaser certifies that it is not a “consumer” within the meaning of the Texas Deceptive Trade Practices Consumer Protection Act, Subchapter E of Chapter 17, Sections 17.41, et seq., of the Texas Business and Commerce Code, (as amended, the “DTPA”). Purchaser covenants, for itself and for and on behalf of any successor or assignee, that if the DTPA is applicable to this Agreement, (a) Purchaser is a “business consumer” as that term is defined in the DTPA, (b) AFTER CONSULTATION WITH ATTORNEYS OF PURCHASER’S OWN SELECTION, PURCHASER HEREBY VOLUNTARILY WAIVES AND RELEASES ALL OF PURCHASER’S RIGHTS AND REMEDIES UNDER THE DTPA AS APPLICABLE TO SELLERS AND SELLERS’ SUCCESSORS AND ASSIGNS AND (c) PURCHASER SHALL DEFEND AND INDEMNIFY THE SELLER GROUP FROM, AND AGAINST ANY AND ALL CLAIMS OF OR BY ANY MEMBER OF THE PURCHASER GROUP OR ANY OF THEIR SUCCESSORS AND ASSIGNS OR ANY OF ITS OR THEIR AFFILIATES BASED IN WHOLE OR IN PART ON THE DTPA ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT.

Section 12.13 Time of the Essence; Calculation of Time. Time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date that is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day that is a Business Day.

Section 12.14 Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Facsimile, .pdf, or other electronic transmission of copies of signatures shall constitute original signatures for all purposes of this Agreement and any enforcement hereof.

IN WITNESS WHEREOF, this Agreement has been signed by each of the Parties as of the Execution Date.
