Section 8.7. Confidentiality Agreement. The Confidentiality Agreement, except to the extent modified herein, will remain in full force and effect; provided, however, that, subject to the provisions of Section 8.12, upon Closing, the Confidentiality Agreement shall terminate, and Seller shall, and shall cause its Affiliates to, not make disclosure to third parties of any confidential or proprietary information relating to a Company or the Properties, except with the prior consent of Buyer or as required by Applicable Law; provided, further, that nothing shall prohibit Seller or its Affiliates from using their knowledge or mental impressions of such information or their general knowledge of the industry or geographic area in the conduct of their respective businesses following Closing. At Closing, and to the extent assignable, Seller will, or will cause its Affiliates to, assign to Buyer the benefits under any and all confidentiality agreements between Seller, or any of its Affiliates, and any third party in connection with the potential sale or other disposition by Seller and its Affiliates of the Companies or the Properties.

Section 8.8. Officer and Director Resignation and Releases.

(a) Neither Buyer nor any Company shall amend, repeal or otherwise modify the Governing Documents of a Company so as to affect adversely the rights thereunder of individuals who at and any time prior to the Closing Date were directors, officers, managers or agents of such Company to indemnification or exculpation. Buyer shall, and shall cause each Company to, honor any indemnification agreements between such Company and any of its directors, officers, managers or agents. In the event any claim or claims are asserted or made pursuant to the indemnification rights set forth in this Section 8.9, all rights to indemnification in respect of any such claim or claims shall continue until the disposition of any and all such claims. Any determination required to be made with respect to whether a person’s conduct complies with the applicable standard of conduct shall be made by independent legal counsel selected by any such director, officer, manager or other agent and reasonably acceptable to Buyer.

(b) Prior to the Closing, each Company will purchase a six (6) year directors’ and officers’ liability insurance and fiduciary liability insurance covering the directors and officers of such Company who are currently covered by such Company’s existing directors’ and officers’ liability insurance or fiduciary liability insurance policies and Buyer will take no action which would interfere with the benefit of such policy during such term.

Section 8.10. Employee Matters. At least five (5) days before the Closing Date, Buyer shall issue, or shall cause its Affiliate to issue, written offers of employment to all Employees whose primary duties involve maintaining or providing services to the Properties in the field (“Field Employees”) subject to each Field Employee passing the standard pre-employment background check and drug-screening procedure of Buyer or its Affiliate. The list of Field Employees is set forth on Section 8.10 of the Disclosure Schedule. Buyer or its Affiliate shall also be permitted to make written offers of employment to Employees who are not designated on Section 8.10 of the Disclosure Schedule as Field Employees only with prior written permission from Seller. All employment offers issued by Buyer or its Affiliate under this Section 8.10 shall be conditioned on the Closing and effective from and after the Closing Date and shall provide for the same regular salary or hourly rate, as applicable, as each Employee had with Seller immediately before the Closing Date for at least one year following the Closing Date, plus substantially similar other terms and conditions of employment (including without limitation position, title, duties, responsibilities, insurance and other employee benefits, bonus opportunity, incentive opportunity, vacation, sick, or other paid leave) as Buyer and its Affiliates provide to similarly situated employees. Buyer shall notify Seller in writing and Buyer and Seller shall

confer at least two (2) days before the Closing Date as to the identities of such Employees who have accepted Buyer’s offers of employment (the “Hired Employees”). Seller will accept the resignation or terminate the employment of the Hired Employees effective as of the date immediately before the Closing Date. On and after the Closing Date, Buyer shall cause each Hired Employee to receive full credit for such Employee’s service with Seller and any predecessor for purposes of eligibility, benefit level and accrual (but not for purposes of benefit accruals under defined benefit pension plans), and vesting under any benefit plans made available to employees of Buyer or any Affiliate of Buyer that employs the Hired Employees in which a Hired Employee participates to the same extent recognized by Seller or Insperity immediately prior to the Closing Date; provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits with respect to the same period of service. On and after the Closing Date, Buyer shall or shall cause any Affiliate that employs the Hired Employees to make reasonable efforts to (A) waive any preexisting condition limitations otherwise applicable to Hired Employees and their eligible dependents under any plan of Buyer or its Affiliate that provides health benefits in which Hired Employees may be eligible to participate on and after the Closing and (B) waive any waiting period limitation or evidence of insurability requirement that would otherwise be applicable to a Hired Employee and his or her eligible dependents on or after the Closing Date, in each case to the extent such Hired Employee or eligible dependent had satisfied any similar limitation or requirement under an analogous employee plan of Seller or Insperity immediately prior to the Closing Date; provided, however, that with respect to any insured plan the obligations of Buyer or its Affiliate hereunder shall be limited to (i) requesting in good faith that the applicable insurer implement such actions, and (ii) incurring any reasonable administrative costs related thereto, if necessary. The provisions of this Section 8.10 are intended to benefit the parties to this Agreement and the Affiliate(s) of each Company referenced in this Section 8.10 and nothing in this Agreement, express or implied, is intended or shall be construed to confer upon or give to any other Person (including for the avoidance of doubt any Employees) other than the parties to this Agreement, the Affiliate(s) of each Company referenced in this Section 8.10, and their respective permitted successors and assigns, any legal or equitable or other rights or remedies under or by reason of any provision of this Agreement.

Section 8.11. Taxes.

(a) Buyer and Seller agree to treat the purchase and sale of the membership interests of CGT for federal income Tax purposes as a purchase and sale of all of the assets of CGT.

(b) Buyer and Seller agree to allocate the Base Purchase Price, as adjusted hereunder, among the membership interests of CGT, the common membership interests of CAM, the CAI Note and the CAI Stock. Buyer and Seller agree to further allocate the amounts allocated to the membership interests of CGT and the common membership interests of CAM among the assets of CGT and CAM. At least ten (10) days prior to the Closing Date, Seller shall prepare and deliver to Buyer an allocation of the Base Purchase Price among the assets of CGT and CAM, the CAI Note and the CAI Stock in a manner consistent with Section 1060 of the Code (the “Purchase Price Allocation”) based upon the fair market values of such assets. (For these purposes, Seller and Buyer agree that the fair market value of the CAI Note, and the portion of the Base Purchase Price to be

allocated to such note, is equal to the total amount due thereunder as of the Closing Date, including principal and accrued interest thereon.) Seller and Buyer shall thereafter use commercially reasonable efforts to agree upon the Purchase Price Allocation on or before the Closing Date. Buyer and Seller anticipate that, in general, the amounts allocated to the Pipeline, Facilities, Permits, Easements and Fee Interests will (because those items were recently purchased or constructed) be equal to the original cost of such Properties.

(c) If an adjustment to the Base Purchase Price is made under this Agreement, the parties shall adjust the Purchase Price Allocation to be consistent with the Purchase Price. Seller and Buyer shall report the transactions contemplated hereby on all Tax Returns (including Form 8594 and all other information returns and supplements thereto required to be filed by the parties under Section 1060 of the Code) in a manner consistent with such Purchase Price Allocation.

(d) If, notwithstanding Section 8.11(b), Seller and Buyer do not agree on the Purchase Price Allocation prior to the Closing Date, Seller shall promptly engage a firm experienced in such matters and reasonably acceptable to Buyer, to conduct an appraisal and determine the fair market value of the assets of CGT and CAM and of the CAI Stock (it being assumed for such purposes that the fair market value of the CAI Note is the amount specified in Section 8.11(b)). The cost of such appraisal shall be borne one-half by Seller and one-half by Buyer. Seller and Buyer agree to allocate the Purchase Price among the assets of CGT and CAM and the CAI Stock and to report the transactions contemplated hereby on all Tax Returns (including Form 8594 and all other information returns and supplements thereto required to be filed by the parties under Section 1060 of the Code) in a manner consistent with the values determined by such appraisal (and of the agreed value of the CAI Note).

(e) Neither Seller nor Buyer shall take, or shall permit any of their respective Affiliates to take, any position inconsistent with the allocation under this Section 8.11 on any Tax Return or otherwise, unless required to do so by Applicable Laws or a “determination” within the meaning of Section 1313(a)(1) of the Code or a similar provisions of state, local or foreign Applicable Law respecting Tax.

(f) Seller will cause to be prepared and filed (i) all federal and state income Tax Returns for CAM and Centrahoma JV that are required to be filed for any Tax period ending on or before the Closing Date, including but not limited to the final federal income Tax Returns of CAM and Centrahoma JV on IRS Form 1065 for the Tax period that ends on the Closing Date, and (ii) all other Tax Returns for the Companies and Centrahoma JV that are required to be filed on or prior to the Closing Date. Seller shall pay or cause to be paid all Taxes reported to be due on such Tax Returns (subject to reimbursement by Buyer if required by Section 8.11(h)); provided, however, that with respect to any Tax Return of Centrahoma JV, Seller shall be responsible only for Taxes attributable to the CAM Centrahoma JV Interest. Buyer and Seller acknowledge and agree that the transactions contemplated under this Agreement will cause a termination of CAM and Centrahoma JV for federal income Tax purposes under Section 708(b)(1)(B) of the Code, and that the respective taxable years of CAM and Centrahoma JV will end on the Closing Date. Buyer will cause to be prepared and filed all Tax Returns for the

Companies and Centrahoma JV that are required to be filed after the Closing Date and shall pay or cause to be paid all Taxes due with respect to such Tax Returns (subject to reimbursement by Seller if required by Section 8.11(h)).

(g) For purposes of this Agreement, the portion of Tax with respect to the income, property or operations of the Company that is attributable to any Tax period that begins on or before the Effective Time and ends after the Effective Time (a “Straddle Period”) will be apportioned between the period of the Straddle Period from before the Effective Time through the Effective Time (the “Pre-Effective Time Straddle Period”) and the period of the Straddle Period that extends after the Effective Time to the end of the Straddle Period (the “Post-Effective Time Straddle Period”) in accordance with this Section 8.11(g). The portion of such Tax attributable to the Pre-Effective Time Straddle Period will (i) in the case of any Taxes other than sales or use taxes, value-added taxes, employment taxes, withholding taxes, and any Tax based on or measured by income, receipts or profits earned during a Straddle Period, be deemed to be the amount of such Tax for the entire taxable period multiplied by a fraction, the numerator of which is the number of days in the Pre-Effective Time Straddle Period and denominator of which is the number of days in the Straddle Period, and (ii) in the case of any sales or use taxes, value-added taxes, employment taxes, withholding taxes, and any Tax based on or measured by income, receipts or profits earned during a Straddle Period, be deemed equal to the amount that would be payable if the Straddle Period ended on and included the Effective Time. The portion of Tax attributable to a Post-Effective Time Straddle Period shall be calculated in a corresponding manner.

(h) Buyer and Seller acknowledge that Tax Returns relating to a Straddle Period may be required to be filed by either Buyer or Seller under Section 8.11(f), and thus the Tax thereon may be initially paid by either Buyer or Seller. If any such Tax is initially paid by Seller, and Seller gives written notice to Buyer that includes a copy of the Tax Return for the Straddle Period and provides reasonable detail concerning the calculation of the portions of Tax attributable to the Post-Effective Time Straddle Period, within 30 days Buyer shall pay Seller the portion properly attributable to such Post-Effective Time Straddle Period. Similarly, if any such Tax is initially paid by Buyer, and Buyer gives written notice to Seller that includes a copy of the Tax Return for the Straddle Period and provides reasonable detail concerning the calculation of the portions of Tax attributable to the Pre-Effective Time Straddle Period, within 30 days Seller shall pay Buyer the portion properly attributable to such Pre-Effective Time Straddle Period, but only to the extent that such Tax is not taken into account in the determination of Net Working Capital or otherwise taken into account as a Purchase Price adjustment under Section 13.1.

(i) Seller and Buyer agree to furnish to each other any and all information and documents reasonably required to comply with Tax and financial reporting requirements and audits.

Section 8.12. Press Releases. Unless consultation is prohibited by Applicable Law, Buyer and Seller shall consult with each other before issuing any press release or otherwise making any public statement with respect to this Agreement or the transactions contemplated hereby and shall not issue any such press release or make any such public statement prior to such consultation (but no approval thereof shall be required).

Section 8.13. Books and Records. At or promptly after Closing, Seller shall deliver to Buyer all records of the Companies that are in Seller’s control, including original minute books and other corporate books and records and accounts. Seller will deliver to Buyer, at Buyer’s expense, all of the rights of way easements, rights of way option agreements, files, assignments, operating records and agreements, engineering records, financial and accounting records (but not including general financial accounting or tax accounting records), and other similar files and records of the Companies which directly relate to the Properties, other than those which Seller considers to be proprietary or confidential, or which Seller cannot provide to Buyer without, in its opinion, breaching, or risking a breach of, agreements with other parties, or waiving, or risking waiving, legal privilege. Buyer agrees that Seller may retain copies of all files transferred to Buyer pursuant to this Section 8.13.

Section 8.14. Rights to “Cardinal” Name, Derivations of Name and Logo. Buyer agrees that Seller shall retain all rights to the “Cardinal” name, logo, and all derivatives thereof, and that Buyer may not use such names, logos, or derivations in any manner without the prior written consent of Seller. Within ninety (90) days after the Closing Date, Buyer shall remove all names and markers used by Seller or the Companies and all variations and derivations thereof and logos relating thereto from the Properties.

Section 8.15. Amendments to the Certificates of Formation of the Companies. Immediately after the Closing, Buyer agrees to file an amendment to each Company’s certificate of formation in a form reasonably acceptable to Seller that provides for a change in the name of such Company, which name does not contain the word “Cardinal” or any derivative thereof and is otherwise reasonably acceptable to Seller.

Section 8.16. HSR Filing. If compliance with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), is required in connection with the transactions contemplated under this Agreement, as promptly as practicable on the date hereof or such other date as shall be mutually agreed by Seller and Buyer, Seller and Buyer will file with the Federal Trade Commission and the Department of Justice, as applicable, the required notification and report forms and will as promptly as practicable furnish any supplemental information which may be requested in connection therewith. Seller and Buyer will request expedited treatment (i.e., early termination) of such filing. Buyer and Seller shall use commercially reasonable efforts to make or modify all other filings and submissions on a prompt and timely basis in connection with the filings required by this Section. Each of Seller and Buyer will bear its own costs and expenses relating to the compliance with this Section.

Section 8.17. Release of Credit Facility Liens.

Article IX.

Buyer’s Due Diligence Examination

Section 9.1. Due Diligence Examination. From the Execution Date until 5:00 p.m. (local time in Dallas, Texas) on the twentieth (20th) day thereafter (the “Examination Period”), each Company shall afford Buyer and its authorized representatives reasonable access during normal business hours to the records of such Company at the offices of Seller for the purposes of determining whether Title Defects (as defined below) exist (“Buyer’s Review”); provided, however, that such investigation shall be upon reasonable notice and shall not unreasonably disrupt the personnel and operations of Seller or such Company or impede the efforts of Seller or such Company to comply with their other obligations under this Agreement. Such books and records shall include files, assignments, operating records and agreements, financial and accounting records, engineering records, in each case insofar as same may now be in existence and in the possession of a Company, excluding, however, any information that a Company is prohibited from disclosing by bona fide, third party confidentiality restrictions; provided, that: (i) any information withheld on such basis shall be identified with as much specificity and detail as reasonably possible without breaching such obligation, and (ii) if requested by Buyer, such Company shall use its Reasonable Efforts to obtain a waiver of any such restrictions in favor of Buyer. Subject to the other provisions of this Agreement, Seller shall give Buyer, or Buyer’s authorized representatives, at all reasonable times during the Examination Period and upon adequate notice to Seller, physical access to the Properties for the purpose of inspecting same. The cost and expense of Buyer’s Review, if any, shall be borne solely by Buyer. Buyer shall not contact any of the customers or suppliers of Seller in connection with the transactions contemplated hereby, whether in person or by telephone, mail or other means of communication, without the specific prior authorization of Seller, which consent shall not be unreasonably withheld.

Section 9.2. Assertion of Title Defects. If Buyer discovers any Title Defects prior to the expiration of the Examination Period, Buyer shall notify the appropriate Company as soon as possible and no later than the expiration of the Examination Period of such alleged Title Defect. To be effective, such notice (“Title Defect Notice”) must (i) be in writing, (ii) be received by the appropriate Company prior to the expiration of the Examination Period, (iii) describe the Title Defect in reasonable detail including the basis therefor (including any supporting documents in possession of Buyer), (iv) identify the specific Properties to which such Title Defect relates, and (v) include the Title Defect Amount as determined by Buyer in good faith. Any matters that may otherwise constitute Title Defects, but of which the appropriate Company has not been specifically notified by Buyer in accordance with the foregoing, shall be deemed to have been waived by Buyer for all purposes. It being expressly understood that Buyer’s sole and exclusive rights and remedies with respect to any matter that constitutes a Title Defect shall be those set forth in this Article IX and Section 12.1(d), and Buyer shall not be entitled to refuse to close (other than pursuant to Section 10.1(d)), to indemnification or any other right or remedy with respect to any Title Defect. Upon the receipt of such effective Title Defect Notice from Buyer, a Company shall have the option, in addition to the rights set forth in this Article IX, but not the obligation, to attempt to cure such Title Defect at any time prior to the Closing.

Section 9.3. Title Defect Amount. With respect to each Title Defect that is properly asserted and not cured on or before the Closing Date, the Base Purchase Price shall be reduced,

subject to Section 9.7, by the Title Defect Amount with respect to such Title Defect Property. The Property (or portion thereof) affected by such uncured Title Defect shall be a “Title Defect Property.” The “Title Defect Amount” resulting from a Title Defect shall be the amount by which the value of the Title Defect Property is reasonably reduced as a result of the existence of such Title Defect and shall be determined in accordance with the following terms and conditions:

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

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

(c) if a Title Defect represents an obligation or Lien upon or other defect in title to the Title Defect Property of a type not described above, the Title Defect Amount shall be determined by taking into account the portion of the Title Defect Property affected by the Title Defect, the legal effect of the Title Defect, the reasonably estimated potential economic effect of the Title Defect over the life of the Title Defect Property, the values and estimated cost to cure placed upon the Title Defect by Buyer and Seller and such other reasonable factors as are necessary to make a proper evaluation; provided, however, that if such Title Defect is reasonably capable of being cured, the Title Defect Amount shall not be greater than the reasonable cost and expense of curing such Title Defect;

(d) if a Title Defect relates to an ownership gap in a right-of-way included in the Property, the Title Defect Amount shall be the reasonable estimated costs and expenses necessary to cure such gap, or alternatively, to construct an alternative route for the pipeline system around such gap, including the cost of acquiring any necessary real property right-of-way and related capital expenditures; and

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

Section 9.4. Defensible Title. “Defensible Title” means, as of the date of this Agreement and the Closing Date, such title and ownership by a Company that:

(a) entitles such Company to operate, maintain, repair, replace and use the Pipeline and the Facilities of such Company in the same manner as they are currently operated;

(b) entitles such Company to use the Easements and Permits of such Company to the extent necessary to operate, maintain, repair, replace and use the Pipeline and Facilities of such Company in the same manner as they are currently used;

(d) reflects that all Consents of such Company which are applicable to or must be complied with in connection with the transaction contemplated by this Agreement have been obtained and complied with to the extent the failure to obtain or comply with the same could render this transaction or any such sale, assignment or transfer (or any right or interest affected thereby) void or voidable.

Section 9.5. Permitted Encumbrances. “Permitted Encumbrances” shall mean (A) Liens for Taxes which are not yet delinquent or which are being contested in good faith and for which adequate reserves have been established; (B) mechanic’s and materialmen’s Liens relating to the Properties, which obligations are not yet due and pursuant to which Seller is not in default; (C) Liens in the ordinary course of business that are minor defects and irregularities in title or other restrictions that are of the nature customarily accepted by prudent purchasers of midstream assets and that do not materially affect the value or use of any property encumbered thereby; (D) all rights to consent by, required notices to, filings with, or other actions by Governmental Entities in connection with the sale or conveyance of midstream assets if the same are customarily obtained routinely and subsequent to such sale or conveyance; (E) required third party consents to assignments and similar agreements unless the failure to obtain such consents would void the transfer or terminate a material right under a Contract or Easement; (F) easements, rights-of-way, servitudes, Permits, surface leases and other rights in respect of surface operations, pipelines, grazing, logging, canals, ditches, reservoirs or the like, and easements for streets, alleys, highways, pipelines, telephone lines, power lines, railways and other easements and rights-of-way, on, over or in respect of any of the Property to the extent such matters do not interfere with operations on the Property; (G) Liens which (i) do not, individually or in the aggregate, materially detract from the value of, or materially interfere with, the operation, maintenance, repair, replacement and/or use of the Properties subject thereto or affected thereby or (ii) are of a nature that would be reasonably acceptable to a prudent owner or operator of natural gas assets and facilities of a type similar to the Properties; (H) rights reserved to or vested in any municipality or governmental, statutory or public authority to control or regulate any of the Property in any manner, and all Applicable Laws, rules and orders of governmental authority; (I) Liens created by Buyer or its successors and assigns; (J) any Lien granted by a third party to encumber properties or assets owned by such third party which also encumbers the Easements; and (K) any deed of trust, mortgage or other Lien that will be fully released at Closing.

Section 9.6. Title Defects. “Title Defect” shall mean a defect exists (A) that causes Seller to not have Defensible Title to the Pipeline, Facilities, Easements or Permits, and (B) for which a Title Defect Notice has been timely and otherwise validly delivered. Notwithstanding any other provision in this Agreement to the contrary, the following matters shall not constitute, and shall not be asserted as, a Title Defect: (1) defects or irregularities arising out of lack of corporate authorization or variation in corporate or entity name; (2) defects or irregularities that have been cured or remedied by the applicable statutes of limitation or statutes for prescription; (3) defects or irregularities in the chain of title consisting of the failure to recite marital status in documents or omissions of heirship Proceedings, and (4) Permitted Encumbrances. Notwithstanding the foregoing, no Title Defect may be asserted with respect to the Properties listed on Section 4.24 of the Disclosure Schedule.

Section 9.7. Base Purchase Price Adjustments for Title Defects.

(a) If a Company and Buyer are unable to reach an agreement as to whether a Title Defect exists or the Title Defect Amount applicable to any Title Defect, the provisions of Article XVII shall be applicable.

(b) Notwithstanding anything to the contrary contained in this Agreement, if the Base Purchase Price adjustment with respect to a particular Title Defect which would result from the above provided for procedures does not exceed Fifty Thousand Dollars ($50,000) (“Title Defect Threshold”), no adjustment shall be made for such Title Defect, it being expressly understood that if the adjustment for such Title Defect exceeds the Title Defect Threshold, the entire Title Defect Amount for such Title Defect shall be included in the calculation of the total amount of all Title Defects for which an adjustment is to be made pursuant to this Article IX (“Total Defect Amount”). In the event the Total Defect Amount does not exceed one and a half percent (1.5%) of the Base Purchase Price, then no adjustment of the Base Purchase Price shall occur. If the Total Defect Amount, in the aggregate, exceeds one and a half percent (1.5%) of the Base Purchase Price, the Base Purchase Price shall be adjusted by the amount by which the Total Defect Amount exceeds one and a half percent (1.5%) of the Base Purchase Price.

Article X.

(a) No later than sixty (60) calendar days after the Closing Date (or such later date as mutually agreed by Buyer and Seller), Seller shall prepare and deliver to Buyer (i) balance sheets of the Companies (on a combined basis) and Centrahoma JV as of the Effective Time (together with supporting documentation reasonably necessary for Buyer to verify each estimated balance sheet, the “Final Balance Sheets”), (ii) worksheets showing Seller’s calculation of the Net Working Capital derived from the Final Balance Sheets (based upon, and subject to the adjustments set forth in, the definitions of Current Assets and Current Liabilities as set forth herein) (the “Final Net Working Capital”), and (iii) Seller’s calculation of the Purchase Price Adjustment Amount (“Final Purchase Price Adjustment Amount”), in each case, together with a worksheet showing the difference, if any, between any Estimated Closing Item and the corresponding Final Closing Item (as defined below). The Final Balance Sheets, the Final Net Working Capital and the Final Purchase Price Adjustment Amount (collectively, the “Final Closing Items”) shall be prepared on a basis consistent with past practice of Seller and consistent with the principles and assumptions used in preparation of the Estimated Closing Items. If Seller does not deliver the Final Closing Items in accordance with this Section 13.3(a) on or before the sixtieth (60^th) calendar day after the Closing Date (or such later date as mutually agreed by Buyer and Seller), Buyer shall have the right to prepare such Final Closing Items on or before the ninetieth (90^th) day after the Closing Date (or such later date as mutually agreed by Buyer and Seller), in which case the relative obligations of Buyer and Seller in the remainder of this Section 13.3 shall be switched. Buyer and Seller shall promptly provide to each other all documents reasonably requested by the other to verify any of the items set forth in the Final Closing Item calculations. Buyer shall have the right for thirty (30) days following receipt of the Final Closing Items to object to the Final Balance Sheet(s) and the proposed calculation of the Final Purchase Price Adjustment Amount. Buyer and its Representatives shall be entitled to access during normal business hours to all books and records of Buyer and Centrahoma JV as may be reasonably requested by Buyer for the purpose of this Section 13.3. Any objection made by Buyer shall be made in writing and shall set forth such objection in reasonable detail. Buyer shall be deemed to have waived any rights to object under this Section 13.3 unless Buyer furnishes its written objections to Seller within such thirty (30) day period. If Buyer delivers an objection within such thirty (30) day period, then Buyer and Seller shall endeavor in good faith to resolve the objections. If, at the end of a fifteen (15) day period from the date of delivery of any objection by Buyer or such longer period as may be mutually agreed by Buyer and Seller, there are any objections that remain in dispute, then the remaining objections in dispute shall be submitted for

resolution to an independent accounting firm to be selected jointly by Seller and Buyer within the following five (5) Business Days (the “Referee”). The Referee shall determine the Final Purchase Price Adjustment Amount as promptly as reasonably practicable after the objections that remain in dispute are submitted to it, but in any event within thirty (30) days after such objections that remain in dispute are submitted to it. If any objections are submitted to the Referee for resolution, (i) each of Buyer and Seller shall furnish to the Referee such workpapers and other documents and information relating to such objections as the Referee may request and are reasonably available to that Party (or its independent public accountants) and will be afforded the opportunity to present to the Referee any material relating to the determination of the matters in dispute and to discuss such determination with the Referee; (ii) the Referee must adopt the amount of the Final Purchase Price Adjustment Amount submitted by either Buyer or Seller and may not adopt any other amount; (iii) the determination by the Referee of the Final Purchase Price Adjustment Amount, as set forth in a written notice delivered to both Buyer and Seller by the Referee, shall be made in accordance with this Agreement and shall be binding and conclusive on the parties and, absent manifest error, shall constitute an arbitral award that is final, binding and unappealable and upon which a judgment may be entered by a court having jurisdiction thereof; and (iv) the fees and expenses of the Referee shall be paid (1) by Buyer if the Referee adopts the Final Purchase Price Adjustment Amount submitted by Seller and (2) by Seller if the Referee adopts the Final Purchase Price Adjustment Amount submitted by Buyer. The Referee and procedures set forth herein shall be the sole method for resolving any disputes regarding the Final Purchase Price Adjustment Amount or the provisions of this Section 13.3 in lieu of the provisions set forth in Article XVII and Section 18.6.

(b) Following the final determination of the Final Purchase Price Adjustment Amount as set forth in Section 13.3(a), if the cumulative amount payable to either Buyer or Seller (“Final Payment Amount”) is more than Fifty Thousand Dollars ($50,000), the amount of the Final Payment Amount in excess of Fifty Thousand Dollars ($50,000) shall be promptly (but in any event within five (5) Business Days of the determination of the Final Payment Amount) paid by wire transfer in immediately available funds to Buyer or Seller, as applicable, to an account designated by such payee.

Section 13.4. Adjustments to Purchase Price. All amounts to be paid under this Article XIII shall be deemed to be adjustments to the Purchase Price for Tax purposes.

Article XIV.

Indemnification

Section 14.1. Indemnification by Buyer. From and after the Closing, Buyer shall indemnify, defend and hold Seller (and its Affiliates and Encap, their respective successors and assigns and their respective owners, directors, officers, managers and employees) harmless from and against any and all Damages (individually a “Seller’s Indemnified Claim” and collectively “Seller’s Indemnified Claims”) to the extent arising out of or resulting from:

THE FOREGOING INDEMNIFICATIONS BY BUYER SHALL APPLY WHETHER OR NOT SUCH DUTIES, OBLIGATIONS OR LIABILITIES, OR SUCH CLAIMS, ACTIONS, CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS OR EXPENSES ARISE OUT OF (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SIMPLE NEGLIGENCE, CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT INCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF ANY INDEMNITEE, (ii) STRICT LIABILITY, OR (iii) ANY VIOLATION OF ANY LAW, RULE, REGULATION OR ORDER RELATED TO THE OWNERSHIP OR OPERATION OF THE PROPERTIES, INCLUDING APPLICABLE ENVIRONMENTAL LAWS.

(i) any misrepresentation or breach of any warranty, covenant or agreement of Seller or a Company contained in this Agreement that survives the Closing for the period of such survival as set forth in Section 14.3;

(ii) those matters disclosed in Section 3.11 of the Disclosure Schedule; or

(iii) except to the extent taken into account in the determination of Net Working Capital or otherwise taken into account as a Purchase Price adjustment under Section 13.1, any Taxes of the Companies or related to the Properties for which Seller is responsible under this Agreement.

(b) THE FOREGOING INDEMNIFICATIONS BY SELLER SHALL APPLY WHETHER OR NOT SUCH DUTIES, OBLIGATIONS OR LIABILITIES, OR SUCH CLAIMS, ACTIONS, CAUSES OF ACTION, LIABILITIES, DAMAGES, LOSSES, COSTS OR EXPENSES ARISE OUT OF (i) NEGLIGENCE (INCLUDING SOLE NEGLIGENCE, SIMPLE NEGLIGENCE, CONCURRENT NEGLIGENCE, ACTIVE OR PASSIVE NEGLIGENCE, BUT EXPRESSLY NOT INCLUDING GROSS NEGLIGENCE OR WILLFUL MISCONDUCT) OF ANY INDEMNITEE, (ii)

STRICT LIABILITY, OR (iii) ANY VIOLATION OF ANY LAW, RULE, REGULATION OR ORDER RELATED TO THE OWNERSHIP OR OPERATION OF THE PROPERTIES, INCLUDING APPLICABLE ENVIRONMENTAL LAWS.

(c) Notwithstanding anything to the contrary, it is expressly understood that Seller shall not have any obligation to defend, indemnify and hold harmless Buyer (or its owners, directors, officers, and employees) with respect to any Buyer’s Indemnified Claims for any breach of a representation or warranty under this Agreement or for breach of Section 8.18 unless the aggregate of such Buyer’s Indemnified Claims exceeds the Deductible, and in the event such Buyer’s Indemnified Claims exceed the Deductible, only the value of Damages in excess of the Deductible shall be considered in applying Section 14.2(a); provided, however, that the Deductible shall not apply with respect to any Buyer’s Indemnified Claims for any breach of the Fundamental Representations or for Damages arising out of or resulting from those matters disclosed in Section 3.11 of the Disclosure Schedule. In no event shall Seller have liability for Damages with respect to any Buyer’s Indemnified Claims for any breach of a representation or warranty under this Agreement or for breach of Section 8.18 in excess of the Cap; provided, however, that the Cap shall not apply with respect to any Buyer’s Indemnified Claims for any breach of the Fundamental Representations or for Damages arising out of or resulting from those matters disclosed in Section 3.11 of the Disclosure Schedule.

(d) Nothing in this Article XIV shall apply to Damages with respect to any and all Title Defects, the Damages with respect to which shall be governed exclusively by Article IX.

(e) Notwithstanding anything to the contrary in this Agreement, Buyer (and its Affiliates, their respective successors and assigns and their respective owners, directors, officers, and employees) shall be deemed not to have suffered any Damages under this Section 14.2 arising from claims based on specific types of assets, liabilities, revenues and expenses including in the calculation of the Purchase Price or in the preparation of the Final Balance Sheet. It is the intent of the Parties that (i) the procedures set forth in Article XIII and the dispute resolution procedures referenced in Article XVII shall provide the sole and exclusive remedies for claims relating to the preparation of the Final Balance Sheet and the determination of the Purchase Price and (ii) Buyer shall not have recourse pursuant to Section 14.2 for breaches of representations and warranties contained in this Agreement to the extent that the facts constituting any such breaches are taken into account in preparing the Final Balance Sheet pursuant to Section 13.3 or in determining the Purchase Price.

Section 14.3. Survival of Provisions.

(a) All representations and warranties shall survive the Closing for the Survival Period.

(b) Except for the covenants contained in Section 2.1, Article X and Section 18.10, which shall survive the Closing indefinitely, and the indemnity obligation of Seller under Section 14.2(b), which shall survive for the statute of limitations applicable to such

Taxes plus 60 days, all covenants of Seller, a Company or Buyer contained in this Agreement shall survive for a period of six (6) months after the Closing (i) except for any covenant which by its terms otherwise terminates as of a specific date or is only made for a specified period and (ii) except for the covenants contained in Section 8.8 (Officer and Director Resignation and Release) and Section 8.9 (Indemnification of Officers and Directors), which shall survive the Closing without limitation; provided that to the extent any representation or warranty survives for a longer period of time, the covenants set forth in Section 14.2 shall survive for such longer period of time solely with respect to such representation and warranty or covenant.

(c) The indemnity for Taxes contained in Section 14.2(b) shall survive for the applicable statute of limitations and sixty (60) days thereafter.

(d) Written notice of any claim by Buyer for indemnification from Seller under Section 14.2 arising during the Survival Period must be given by Buyer to Seller no later than the end of the Survival Period as a condition precedent to the right to enforce such claim for indemnification. In the event a Buyer’s Indemnified Claim is timely and properly asserted, the covenants set forth in Section 14.2 shall survive until such Buyer’s Indemnified Claim is satisfied, but only with respect to such timely and properly asserted Buyer’s Indemnified Claim.

Section 14.4. Notice of Claim. If indemnification pursuant to Section 14.1 or Section 14.2 is sought, the party seeking indemnification (the “Indemnitee”) shall give written notice to the indemnifying party of an event giving rise to the obligation to indemnify, describing in reasonable detail the factual basis for such claim, and shall allow the indemnifying party to assume and conduct the defense of the claim or action with counsel reasonably satisfactory to the Indemnitee, and cooperate with the indemnifying party in the defense thereof; provided, however, that the omission to give such notice to the indemnifying party shall not relieve the indemnifying party from any liability which it may have to the Indemnitee, except to the extent that the indemnifying party is prejudiced by the failure to give such notice and as otherwise provided in Section 14.3. The Indemnitee shall have the right to employ separate counsel to represent the Indemnitee if the Indemnitee is advised by counsel that an actual or likely conflict of interest makes it advisable for the Indemnitee to be represented by separate counsel and the reasonable expenses and fees of such separate counsel shall be paid by the indemnifying party.

Section 14.5. No Commissions Owed. Seller agrees to indemnify, defend and hold Buyer (and its partners and its and their Affiliates, and the respective owners, officers, directors, employees, attorneys, contractors and agents of such parties) harmless from and against any and all claims, actions, causes of action, liabilities, damages, losses, costs or expenses (including, without limitation, court costs and attorneys fees) of any kind or character arising out of or resulting from any agreement, arrangement or understanding alleged to have been made by, or on behalf of, Seller or a Company with any broker or finder in connection with this Agreement or the transaction contemplated hereby. Buyer agrees to indemnify, defend and hold Seller (and its partners and its and their Affiliates and the respective owners, officers, directors, employees, attorneys, contractors and agents of such parties) harmless from and against any and all claims, actions, causes of action, liabilities, damages, losses, costs or expenses (including, without limitation, court costs and attorneys fees) of any kind or character arising out of or resulting from

any agreement, arrangement or understanding alleged to have been made by, or on behalf of, Buyer, with any broker or finder in connection with this Agreement or the transaction contemplated hereby.

Section 14.6. Net Amounts. Any amounts recoverable by any party pursuant to this Article XIV with respect to any Buyer’s Indemnified Claims or Seller’s Indemnified Claims, as the case may be, shall be decreased by any insurance proceeds or other amounts relating to such Buyer’s Indemnified Claims or Seller’s Indemnified Claims, as the case may be, paid to such Indemnitee by any Person (other than any Affiliate of such Indemnitee) not a party to this Agreement. To the extent that any Buyer’s Indemnified Claims or Seller’s Indemnified Claims relate to CAI and give rise to a tax benefit to the Indemnitee making the claim for indemnification (or an Affiliate of such Indemnitee), then the claim for indemnification shall be reduced by an amount equal to such tax benefit realized by such Indemnitee.

Section 14.7. Manner of Payment and Release of Escrow Account. Except with respect to any outstanding Dispute arising from or relating to Article XIV (including this Section 14.7) which is in the process of resolution under Section 17.1:

(a) Any indemnification with respect to any Buyer’s Indemnified Claims or Seller’s Indemnified Claims pursuant to this Article XIV shall be effected by wire transfer of immediately available funds from the indemnifying party (or the Escrow Account, as applicable) to an account designated in writing by the applicable Indemnitee within ten (10) Business Days after a final determination thereof;

(b) In the event any amount is owed by Seller pursuant to Section 14.2, such amount shall first be satisfied from the Escrow Account (to the extent funds from the Escrow Account are sufficient); and

(c) In the event that any funds remain in the Escrow Account on the Escrow Termination Date, Buyer and Seller shall execute joint written instructions to the Escrow Agent instructing the Escrow Agent to release such funds to Seller; provided, that, if there are any Buyer’s Indemnified Claims hereunder that are properly pending but unresolved on such date, the applicable portion of funds in the Escrow Account that are subject to such claims shall not be released until such applicable claims are finally resolved in accordance with this Agreement at which time Buyer and Seller shall execute joint written instructions to the Escrow Agent instructing the Escrow Agent to release such funds to Seller.

Article XV.

Casualty Losses

In the event of damage by fire or other casualty to the Properties after the date of this Agreement but prior to the Closing (“Casualty Loss”), then subject to Section 12.1: (a) this Agreement shall remain in full force and effect; (b) Buyer shall take title to the Property affected by such damage without reduction of the Purchase Price; and (c) Seller shall, at Seller’s sole election, either (i) assign to Buyer any property damage insurance claims related to such damage and pay any deductibles, or (ii) repair or replace such damaged property to a condition similar to

the condition of the affected Property immediately prior to the Casualty Loss and retain all insurance claims and payments with respect thereto. Until the Closing Date, Seller shall maintain the existing insurance coverage, and in the event of a Casualty Loss which is not covered by insurance, except as provided in this Section, Seller shall have no obligation to Buyer with respect thereto; provided that, if Buyer so requests, and if Seller has not repaired the damage or replaced the affected Property, Seller will assign any rights it may have against third parties with respect to such damage.

Section 17.1. Dispute Resolution.

(a) Except as otherwise provided in Article XIII and Section 18.10, any and all claims, disputes, controversies or other matters in question arising out of or relating to this Agreement (all of which are referred to herein as “Disputes”) shall be resolved solely in accordance with this Section 17.1, even though some or all of such Disputes are allegedly extra contractual in nature, whether such Disputes sound in contract, tort, or otherwise, at law or in equity, under state or federal law, whether provided by statute or the common law, for damages or any other relief.

(b) If a Dispute occurs that the senior representatives of the parties responsible for the transaction contemplated by this Agreement have been unable, in good faith, to settle or agree upon within a period of fifteen (15) days after written notice is given of such Dispute, Seller shall nominate and commit one of its senior officers, and Buyer shall nominate and commit one of its senior officers, to meet at a mutually agreed time and place not later than thirty (30) days after written notice of the Dispute to attempt to resolve same. If such senior management have been unable to resolve such Dispute within a period of fifteen (15) days after such meeting, or if such meeting has not occurred within forty-five (45) days following such written notice of such Dispute, then any party shall have the right, by written notice to the other, to resolve the Dispute (i) through the relevant Independent Expert pursuant to Section 17.1(c).

(c) Each party shall have the right to submit Disputes (including the existence of a Title Defect or the Title Defect Amounts attributable thereto), to an independent expert appointed in accordance with this Section 17.1(c) (each, an “Independent Expert”), who shall serve as sole arbitrator. The Independent Expert shall be appointed by mutual agreement of Seller and Buyer from among candidates with experience and expertise in the area that is the subject of such Dispute, and failing such agreement, such Independent Expert for such Dispute shall be selected in accordance with the Rules (as hereinafter defined). Disputes to be resolved by an Independent Expert shall be resolved in accordance with mutually agreed procedures and rules and failing such agreement, in accordance with the rules and procedures (including timing) for arbitration provided in

Section 17.1(d). The Independent Expert shall be instructed by the parties to resolve such Dispute as soon as reasonably practicable in light of the circumstances. The decision and award of the Independent Expert shall be binding upon the parties as an award under the Federal Arbitration Act and final and nonappealable to the maximum extent permitted by law, and judgment thereon may be entered in a court of competent jurisdiction and enforced by any party as a final judgment of such court. If the parties have any Dispute as to the selection of an Independent Expert or an Independent Expert is not selected within ten (10) days of the notice set forth in Section 17.1(b), any party may elect to proceed with arbitration in accordance with Section 17.1(d).

(d) Any Dispute that is not resolved pursuant to the foregoing provisions of this Section 17.1 shall be settled exclusively and finally by arbitration in accordance with this Section 17.1(d).

(i) Such arbitration shall be conducted pursuant to the Federal Arbitration Act. The validity, construction, and interpretation of this Section 17.1(d), and all procedural aspects of the arbitration conducted pursuant hereto, including the determination of the issues that are subject to arbitration (i.e., arbitrability), the scope of the arbitrable issues, allegations of “fraud in the inducement” to enter into this Agreement or this arbitration provision, allegations of waiver, laches, delay or other defenses to arbitrability, and the rules governing the conduct of the arbitration (including the time for filing an answer, the time for the filing of counterclaims, the times for amending the pleadings, the specificity of the pleadings, the extent and scope of discovery, the issuance of subpoenas, the times for the designation of experts, whether the arbitration is to be stayed pending resolution of related litigation involving third parties not bound by this Agreement, the receipt of evidence, and the like), shall be decided by the arbitrators. The arbitration shall be conducted using the rules (but not the auspices) of the American Arbitration Association (the “Rules”) or any successor when not in conflict with the Federal Arbitration Act.

(ii) All arbitration proceedings hereunder shall be conducted in Tarrant County, Texas or such other mutually agreeable location.

(iii) Arbitration shall be commenced by the initiating party (the “claimant”) giving the other party (the “respondent”) written notice of the intention to arbitrate (the “Arbitration Demand”), which shall contain a statement setting forth the nature of the dispute, the names and addresses of all other parties, the amount involved, if any, the remedy sought, and the hearing locale requested.

(iv) All arbitration proceedings hereunder shall be before a panel of three (3) arbitrators. Each Person acting as an arbitrator must be impartial and independent and have at least ten (10) years of experience in or relating to the oil and gas industry. Seller and Buyer shall each appoint one arbitrator within fifteen (15) days after the Arbitration Demand and the third arbitrator shall be selected by the arbitrators appointed by Seller and Buyer within fifteen (15) days after their

appointment. If either Seller or Buyer has failed to designate an arbitrator within fifteen (15) days after the Arbitration Demand or if the two appointed arbitrators shall fail to select a third arbitrator within fifteen (15) days after their appointment, then an arbitrator shall be selected by a U.S. District Judge for the Northern District of Texas. Except as to the impartiality or independence of an arbitrator, no party may dispute the appointment of any arbitrator selected by the other party.

(v) Discovery shall be made pursuant to the Federal Rules of Civil Procedure and completed within sixty (60) days of selection of the third arbitrator.

(vi) In deciding the substance of the Dispute, the arbitrators shall refer to the substantive laws of the State of Texas for guidance (excluding choice-of-law principles that might call for the application of the laws of another jurisdiction). Matters relating to arbitration shall be governed by the Federal Arbitration Act.

(vii) The arbitrators shall conduct a hearing within ninety (90) days after appointment of the third arbitrator, and shall render a final decision completely disposing of the Dispute that is the subject of such proceedings as within thirty (30) days after the final hearing. The parties shall instruct the arbitrators to impose time limitations they consider reasonable for each phase of such proceeding, including, without limitation, limits on the time allotted to each party for the presentation of its case and rebuttal. The arbitrators shall actively manage the proceedings as they deem best so as to make the proceedings fair, expeditious, economical and less burdensome than litigation. To provide for speed and efficiency, the arbitrators may: (i) limit the time allotted to each party for presentation of its case; and (ii) exclude testimony and other evidence they deem irrelevant or cumulative.

(viii) Notwithstanding any other provision in this Agreement to the contrary, the parties expressly agree that the arbitrators shall have absolutely no authority to award consequential, incidental, special, treble, exemplary or punitive damages of any type under any circumstances regardless of whether such damages may be available under Texas law, or any other laws, or under the Federal Arbitration Act or the Rules.

(ix) The final decision of the arbitrators shall be in writing, be as brief as possible, set forth the reasons for such final decision, and if the arbitrators award monetary damages to either party, contain a certification by the arbitrators that they have not included any incidental, special, treble, exemplary or punitive damages. To the fullest extent permitted by law, the arbitration proceeding and the arbitrators’ decision and award shall be maintained in confidence by the parties and the parties shall instruct the arbitrators to likewise maintain such matters in confidence.

(x) The fees and expenses of the arbitrators shall be borne equally by Seller and Buyer.

(xi) The decision and award of the arbitrators shall be binding upon the parties and final and nonappealable to the maximum extent permitted by law, and judgment thereon may be entered in a court of competent jurisdiction and enforced by any party as a final judgment of such court.

Article XVIII.

Miscellaneous Matters

After the Closing, Seller shall execute and deliver, and shall otherwise cause to be executed and delivered, from time to time, such further instruments, notices, division orders, transfer orders and other documents, and do such other and further acts and things, as may be reasonably necessary to more fully and effectively grant, convey and assign the Securities and the Properties to Buyer.

After consultation with an attorney of Buyer’s own selection, Buyer voluntarily consents to this waiver. To evidence Buyer’s ability to grant such waiver, Buyer represents to Seller that it (a) is in the business of seeking or acquiring, by purchase or lease, goods or services for commercial or business use, (b) has knowledge and experience in financial and business matters that enable it to evaluate the merits and risks of the transactions contemplated hereby, (c) is not in a significantly disparate bargaining position, and (d) has consulted with, and is represented by, an attorney of Buyer’s own selection in connection with this transaction, and such attorney was not directly or indirectly identified, suggested, or selected by Seller or an agent of Seller.

Each party shall bear and pay all expenses (including, without limitation, legal fees) incurred by it in connection with the transaction contemplated by this Agreement. NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY NEITHER PARTY SHALL HAVE ANY OBLIGATIONS WITH RESPECT TO THIS AGREEMENT, OR OTHERWISE IN CONNECTION HEREWITH, FOR ANY INDIRECT, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES. For purposes of the foregoing, actual damages may, however, include indirect, special, consequential, exemplary or punitive damages to the extent (i) the injuries or losses resulting in or giving rise to such damages are incurred or suffered by a Person which is not an Indemnitee pursuant to the Agreement or an Affiliate of such Indemnitee and (ii) such damages are recovered against an Indemnitee by a Person which is not Indemnitee or an Affiliate of such Indemnitee. This Section shall operate only to limit a party’s liability and shall not operate to increase or expand any contractual obligation of a party hereunder or cause any contractual obligation of a party hereunder to survive longer than provided in Section 14.3.

Section 18.4. Transfer Taxes. No Transfer Tax will be collected at Closing from Buyer in connection with this transaction. If, however, this transaction is later deemed to be subject to Transfer Tax, for any reason, Buyer agrees to be solely responsible for, and shall indemnify and hold Seller harmless, for any and all Transfer Taxes due by virtue of this transaction and Buyer shall remit such Transfer Taxes at that time. Seller and Buyer agree to cooperate with each other in demonstrating that the requirements for exemptions, if any, from such Transfer Taxes have been met. Notwithstanding anything to the contrary herein, any Transfer Taxes imposed as a result of the transactions contemplated by Section 8.3 shall be solely the responsibility of Seller.

Section 18.5. Entire Agreement. This Agreement contains the entire understanding of the parties hereto with respect to subject matter hereof and supersedes all prior agreements, understandings, negotiations, and discussions among the parties with respect to such subject matter.

Section 18.6. Choice of Law, etc. Without regard to principles of conflicts of law, this Agreement, and all claims of causes of action (whether in contract or tort) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement (including any claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter into this Agreement) shall be construed and enforced in accordance with and governed by the laws of the State of Texas applicable to contracts made and to be performed entirely within such state and the laws of the United States of America, except that, to the extent that the law of a state in which a portion of the Properties is located (or which is otherwise applicable to a portion of the Properties) necessarily governs, the law of such state shall apply as to that portion of the property located in (or otherwise subject to the laws of) such state. EACH PARTY HERETO WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION, SUIT OR PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT.

Section 18.7. Time of Essence. Time is of the essence in this Agreement.

Section 18.8. No Assignment. This Agreement shall be binding on and inure to the benefit of the parties hereto and their respective successors and assigns, provided that neither party shall have the right to assign this Agreement, including any indemnification rights, or any obligations or benefits hereunder, without the prior written consent of the other party first having been obtained. Any transfer in absence of such consent shall be null and void.

Section 18.9. Counterpart Execution. For execution, this Agreement may be executed in counterparts, all of which are identical and all of which constitute one and the same instrument. It shall not be necessary for Buyer, Seller and the Companies to sign the same counterpart. This instrument may be validly executed and delivered by facsimile or other electronic transmission.

Section 18.10. Exclusive Remedy.

(a) THE PARTIES HERETO HAVE VOLUNTARILY AGREED TO DEFINE THEIR RIGHTS, LIABILITIES AND OBLIGATIONS RESPECTING THE SUBJECT MATTER OF THIS AGREEMENT EXCLUSIVELY IN CONTRACT PURSUANT TO THE EXPRESS TERMS AND PROVISIONS OF THIS AGREEMENT; AND, WITHOUT LIMITING THE RIGHT OF ANY PARTY TO RELY ON THE REPRESENTATIONS AND WARRANTIES MADE TO SUCH PARTY IN ARTICLE III, ARTICLE IV, ARTICLE V, AND ARTICLE VII HEREIN, THE PARTIES HERETO EXPRESSLY DISCLAIM THAT THEY ARE OWED ANY DUTIES OR ARE ENTITLED TO ANY REMEDIES NOT EXPRESSLY SET FORTH IN THIS AGREEMENT. FURTHERMORE, THE PARTIES EACH HEREBY ACKNOWLEDGE THAT THIS AGREEMENT EMBODIES THE JUSTIFIABLE EXPECTATION OF SOPHISTICATED PARTIES KNOWLEDGEABLE IN BUSINESS AND DERIVED FROM VOLUNTARY, ARM’S LENGTH NEGOTIATIONS; ALL PARTIES TO THIS AGREEMENT SPECIFICALLY ACKNOWLEDGE THAT NO PARTY HAS ANY SPECIAL RELATIONSHIP WITH ANOTHER PARTY THAT WOULD JUSTIFY ANY EXPECTATION BEYOND THAT OF AN ORDINARY BUYER AND AN ORDINARY SELLER IN AN ARM’S LENGTH TRANSACTION; THAT IS, NO FIDUCIARY RELATIONSHIP OR DUTY EXISTS. THE SOLE AND EXCLUSIVE REMEDY FOR ANY BREACH OF THE TERMS AND PROVISIONS OF THIS AGREEMENT (INCLUDING ANY REPRESENTATIONS AND WARRANTIES SET FORTH HEREIN) SHALL BE THOSE REMEDIES AVAILABLE AT LAW OR, SOLELY TO THE EXTENT PROVIDED IN SECTION 18.10(B), IN EQUITY FOR BREACH OF CONTRACT ONLY (AS SUCH CONTRACTUAL REMEDIES MAY BE FURTHER LIMITED OR EXCLUDED PURSUANT TO THE EXPRESS TERMS OF THIS AGREEMENT); AND, WITHOUT LIMITING THE RIGHT OF ANY PARTY TO RELY ON THE REPRESENTATIONS AND WARRANTIES MADE TO SUCH PARTY IN , ARTICLE IV, ARTICLE V, AND ARTICLE VII HEREIN, THE PARTIES HERETO HEREBY EXPRESSLY DISCLAIM RELIANCE ON THE OTHER PARTY AND CLEARLY AND UNEQUIVOCALLY WAIVE AND RELEASE ANY AND ALL TORT CLAIMS AND CAUSES OF ACTION THAT MAY BE BASED UPON, ARISE OUT OF OR RELATE TO THIS AGREEMENT, OR THE NEGOTIATION, EXECUTION OR PERFORMANCE OF THIS AGREEMENT (INCLUDING ANY TORT CLAIM OR CAUSE OF ACTION BASED UPON, ARISING OUT OF OR RELATED TO ANY REPRESENTATION OR WARRANTY MADE IN OR IN CONNECTION WITH THIS AGREEMENT OR AS AN INDUCEMENT TO ENTER INTO THIS AGREEMENT, INCLUDING RELEASING CLAIMS FOR BREACH OF FIDUCIARY DUTY, FRAUD, FRAUDULENT INDUCEMENT, AND FRAUDULENT INDUCEMENT INTO THE ARBITRATION CLAUSE). WITHOUT LIMITATION OF THE FOREGOING, THE SOLE AND EXCLUSIVE REMEDY OF BUYER FOR ANY AND ALL (A) CLAIMS RELATING TO ANY REPRESENTATIONS, WARRANTIES, COVENANTS AND AGREEMENTS CONTAINED IN THIS AGREEMENT, (B) OTHER CLAIMS PURSUANT TO OR IN CONNECTION WITH THIS AGREEMENT AND (C) OTHER CLAIMS RELATING TO THE PROPERTIES AND THE PURCHASE AND SALE THEREOF SHALL BE ANY RIGHT TO

INDEMNIFICATION FROM SUCH CLAIMS THAT IS EXPRESSLY PROVIDED IN THIS AGREEMENT, AND IF NO SUCH RIGHT OF INDEMNIFICATION IS EXPRESSLY PROVIDED, THEN SUCH CLAIMS ARE HEREBY WAIVED TO THE FULLEST EXTENT PERMITTED BY LAW. EACH PARTY UNDERSTANDS THIS AGREEMENT AND ITS CONTENTS, AND SIGNS THIS AGREEMENT AS ITS OWN FREE ACT. EACH PARTY EXPRESSLY WARRANTS THAT IT HAS BEEN REPRESENTED BY LEGAL COUNSEL IN THIS MATTER, AND LEGAL COUNSEL HAS READ AND EXPLAINED TO EACH PARTY THE ENTIRE CONTENTS OF THIS AGREEMENT, AND ITS WAIVERS AND RELEASES IN FULL. EACH PARTY COVENANTS NOT TO SUE ON CLAIMS RELEASED OR WAIVED BY THIS AGREEMENT, AND AGREES THAT ANY SUCH SUIT SHALL BE A BREACH OF THIS AGREEMENT FOR WHICH THE NONBREACHING PARTY MAY SEEK ACTUAL DAMAGES, WHICH SHALL INCLUDE ATTORNEYS FEES AND COSTS.

(b) If the Closing does not occur due to the breach of Seller, Seller agrees that Buyer’s legal remedies will be inadequate and that the Properties are unique. The sole and exclusive remedy of Buyer shall be the right to specific performance under Applicable Law and Buyer shall not be entitled to recover any monetary damages; provided however, if the foregoing limitation of Buyer’s remedy to specific performance should for any reason be legally unenforceable, then the sole and exclusive remedy of Buyer, in such event, shall instead be any right to recover actual direct damages for such breach.

(c) Upon Closing, Buyer shall also be deemed to have waived, to the fullest extent permitted under Applicable Law, any right to contribution against Seller (including, without limitation, any contribution claim arising under any Applicable Environmental Law) and any and all other rights, claims and causes of action it may have against Seller arising under or based on any federal, state or local statute, law, ordinance, rule or regulation or common law or otherwise.
