(a) From the date hereof through the Closing, Sellers shall afford to Buyers and their authorized Representatives full access, during normal business hours and in such manner as not to unreasonably interfere with normal operation of the business, to the properties, property records, title insurance, title opinions and reports, books, contracts, leases, records and appropriate officers and employees of the Partnership Companies (and of Sellers to the extent related to the business of the Partnership Companies), and shall furnish such authorized Representatives with all financial and operating data, title and property information and records and other information concerning the affairs of any Partnership Company (and of Sellers to the extent related to the business of the Partnership Companies) as Buyers and such Representatives may reasonably request (including, without limitation, planning and preliminary arrangements (including data mapping and testing) for the transfer of data from Sellers to Buyers necessary for post-Closing provision of payroll, benefits and data services); provided, however, that Buyers shall not be entitled to conduct any environmental testing or sampling on or at any properties or Facilities of the Partnership Companies without Sellers’ prior written consent, which consent will not be unreasonably withheld or delayed. Sellers shall have the right to have a Representative present at all times during any such inspections, interviews, and examinations.

(b) Buyers shall hold in confidence all information referred to in subsection (a) above on the terms and subject to the conditions contained in the Confidentiality Agreement. Notwithstanding the foregoing, Buyers shall have no right of access to, and Sellers shall have no obligation to provide to Buyers, information relating to (i) bids received from others in connection with the transactions contemplated by this Agreement and information and analysis (including financial analysis) relating to such bids, (ii) any information the disclosure of which Sellers have reasonably concluded after consultation with counsel would jeopardize any privilege available to a Partnership Company, Sellers or any of their respective Affiliates relating to such information, (iii) any information the disclosure of which would cause a Partnership Company, Sellers or any of their respective Affiliates to breach a confidentiality obligation or (iv) any information the disclosure of which would result in a violation of Law. With respect to clause (iii) above, Sellers represent and warrant that the information not being

disclosed to Buyers could not reasonably be expected to have a Material Adverse Effect on the Partnership Companies or the operation of the business of the Partnership Companies.

(c) From and after the Closing Date until the fifth anniversary of the Closing Date, Sellers will, and will cause each of their subsidiaries and Representatives to, hold in confidence, unless compelled to disclose by judicial or administrative process or by other requirements of applicable Law, all confidential information concerning the Partnership Companies or the business and assets of the Partnership Companies, except to the extent that such information can be shown to have been (i) in the public domain through no fault of Sellers or any of their Representatives, (ii) disclosed by Buyers, their Affiliates or their respective Representatives to a third party without a duty of confidentiality on such third party or (iii) lawfully acquired by Sellers or their Representatives after the Closing Date on a non-confidential basis from sources other than Buyers or the Partnership Companies, but only to the extent that any such source is not bound by a confidentiality agreement or other duty to keep such information confidential.

Sellers agree to provide, and shall cause the Partnership Companies and each of its officers and employees to provide, all cooperation reasonably requested by Buyers, at Buyers’ sole cost and expense, and necessary in connection with (x) the arrangement of any equity or debt financing by Buyers (“Financing”), including (i) preparation of financial statements for use in any offering document prepared by Buyers or their Affiliates and (ii) delivery by the Partnership Companies of any pledge and security documents, lien releases, other definitive financing documents, including any indemnity agreements or other requested certificates or documents relating to the Financing, and (y) the filing of Form 8-K by Buyers or any of their Affiliates under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as a result of the consummation of the transactions contemplated hereby; provided, however, that no such agreements or documents shall impose any monetary obligation or liability on the Partnership Companies prior to the Closing Date or on such officers, employees or Sellers at any time. Sellers and the Partnership Companies shall take all actions reasonably requested by Buyers, at Buyers’ sole cost, to cause KPMG LLP to provide any unqualified opinions, consents or customary comfort letters with respect to the financial statements needed in connection with the Financing and the filing of such Form 8-K. The obligations set forth in this Section 6.3(b) shall survive until the third anniversary of the Closing Date.

Section 6.4 Regulatory Filings. From the date of this Agreement until the Closing:

(a) Each of Buyers and Sellers shall, and shall cause their respective Affiliates to (i) make or cause to be made the filings required of such party or any of its Affiliates under any Laws with respect to the transactions contemplated by this Agreement and to pay any fees due of it in connection with such filings, as promptly as is reasonably practicable, and in any event within 15 Business Days after the date hereof, (ii) cooperate with the other Party and furnish all information in such Party’s possession that is necessary in connection with such other Party’s filings, (iii) use Reasonable Efforts to cause the expiration of the notice or waiting periods under the HSR Act and any other Laws with respect to the transactions contemplated by this Agreement as promptly as is reasonably practicable, (iv) promptly inform the other Party of any communication from or to, and any proposed understanding or agreement with, any Governmental Authority in respect of such filings, (v) consult and cooperate with the other Party in connection with any analyses, appearances, presentations, memoranda, briefs, arguments and opinions made or submitted by or on behalf of any Party in connection with all meetings, actions and proceedings with Governmental Authorities relating to such filings, (vi) comply, as promptly as is reasonably practicable, with any requests received by such Party or any of its Affiliates under the HSR Act and any other Laws for additional information, documents or other materials, and (vii) use Reasonable Efforts to resolve any objections as may be asserted by any Governmental Authority with respect to the transactions contemplated by this Agreement.

(b) In connection with any such filings, Buyers shall cooperate in good faith with Governmental Authorities and undertake promptly any and all action required to complete lawfully the transactions contemplated by this Agreement. Notwithstanding the foregoing, in no event shall Buyers be required to take any action, or agree to take any action, that in the judgment of Buyers would have a material adverse effect on Buyers or on the Partnership Companies or any of their respective Affiliates.

Section 6.5 No-Hire/Non-Solicitation.

(a) For a period of 12 months following the Closing Date, neither Buyers nor any Affiliate of Buyers shall, directly or indirectly, hire or solicit (with the exception of any general solicitation of employment through any general advertising medium in the ordinary course of business) for employment as an employee or consultant, any employee of Sellers or their Affiliates other than a Transferred Employee, unless such employee’s employment is or has been terminated by Sellers and their Affiliates.

(b) For a period of 12 months following the Closing Date, neither Sellers nor any of their Affiliates shall, directly or indirectly, hire or solicit (with the exception of any general solicitation of employment through any general advertising medium in the ordinary course of business) for employment as an employee or consultant, any individual who is identified as a Transferred Employee on the date hereof or who was a Transferred Employee as of the Closing Date, unless such employee’s employment is or has been terminated by Buyers and their Affiliates (including, after the Closing, the Partnership Companies).

Section 6.6 Partnership Guarantees.

(a) Buyers shall use Reasonable Efforts to obtain from the respective beneficiary, in form and substance reasonably satisfactory to Sellers, on or before the Closing, valid and binding written releases of Sellers and their respective Affiliates (other than the Partnership Companies), as applicable, from any liability or obligation, whether arising before, on or after the Closing Date, under any Partnership Guarantees in effect as of the Closing. If any Partnership Guarantee has not been released as of the Closing Date, then Buyers shall continue to use their Reasonable Efforts after the Closing to cause each such unreleased Partnership Guarantee to be released promptly. The Buyers shall be deemed to have met their obligations described in the two immediately preceding sentences if they shall have offered to provide a substitute guarantee, a substitute letter of credit or a substitute surety or performance bond, as applicable, with terms and provisions that are not less favorable to such beneficiary in any material respect than the guarantee, letter of credit or surety or performance bond being replaced. In no event shall the Buyers be obligated to offer to provide guarantees, letters of credit or surety or performance bonds with terms and provisions more favorable to the beneficiary than the guarantee, letter of credit or surety or performance bond being replaced.

(b) Notwithstanding anything to the contrary herein, the Parties acknowledge and agree that at any time on or after 90 days following the Closing Date, the expiration of the Transition Services Agreement, any of SRCG, Genpar and their respective Affiliates may, in its sole discretion, take any action to terminate, obtain release of or otherwise limit its liability under any and all outstanding Partnership Guarantees.

(c) Buyers shall reimburse Sellers for any and all Losses incurred on account of claims and payments made under or for the Partnership Guarantees on or after the Closing Date and the obligations of Buyers hereunder to reimburse Sellers for such Losses shall not be subject to the limitations or conditions contained in Article IX hereof. Notwithstanding the foregoing, Buyers shall not be required to indemnify the Sellers for any Losses attributable to an event or condition, the occurrence or existence of which results in a valid claim by Buyers against the Sellers for indemnity pursuant to Article IX hereof.

Section 6.7 Indebtedness; Termination of Related Party Transactions.

(a) Immediately prior to the Closing, (i) Sellers shall cause the Partnership Companies to distribute to Sellers any Indebtedness due to the Partnership Companies from Sellers or their respective Affiliates (other than the Partnership Companies) and (ii) Sellers shall cancel (or, as applicable, cause their respective Affiliates to cancel) any Indebtedness due from the Partnership Companies to Sellers or their respective Affiliates (other than the Partnership Companies), in each case including interest and other amounts accrued thereon or due in respect thereof.

Prior to the Closing, each of Sellers and Buyers shall give the other Party prompt written notice of (i) any development that is reasonably likely to result in a failure of a condition to the Closing or (ii) the breach of any of its respective representations and warranties or covenants. No such disclosure by any such party shall be deemed to cure any such breach.

Section 6.9 Change of Name; Seller Marks.

(a) As soon as practicable following the Closing Date, but in no event later than 30 days following the Closing Date, Buyers shall cause each of the Partnership Companies, as applicable, to change its name to a name that does not include “Sid,”“Xxx Xxxxxxxxxx,”“SRCG,”“Xxxxxxxxxx” or “Keystone” and to make any necessary legal filings with the appropriate Governmental Authorities to effectuate such changes. Buyers shall hold harmless and indemnify Sellers against all costs, expenses, and damages resulting from or arising in connection with Buyers’ or the Partnership Companies use of the “Sid,”“Xxx Xxxxxxxxxx,”“SRCG,”“Xxxxxxxxxx” or “Keystone” names as provided in this Section 6.9.

(b) Buyers shall obtain no right, title, interest, license or any other right whatsoever to use the words “Sid,”“Xxx Xxxxxxxxxx,”“SRCG,”“Xxxxxxxxxx,”“Keystone” or any trademarks containing or comprising the foregoing, or any trademark confusingly similar thereto or dilutive thereof (collectively, the “Seller Marks”). From and after the Closing, Buyers agree that they shall (i) cause each Partnership Company to cease using the Seller Marks in any manner, directly or indirectly, except for such limited uses as cannot be promptly terminated (e.g., signage, e-mail addresses and the like), and to cease such limited usage of the Seller Marks as promptly as possible after the Closing and in any event within 12 months following the Closing Date, (ii) remove, strike over or otherwise obliterate all Seller Marks from all assets and all other materials owned, possessed or used by any of the Partnership Companies to the extent reasonably practicable and (iii) use Reasonable Efforts to cause any third parties using or licensing Seller Marks on behalf of or with the consent of any Partnership Company, to remove, strike over or otherwise obliterate all Seller Marks from all materials owned, possessed or used by such third parties. The Parties agree, because damages would be an inadequate remedy, that a Party seeking to enforce this Section 6.9 shall be entitled to seek specific performance and injunctive relief as remedies for any breach thereof in addition to other remedies available at law or in equity.

(c) Subject to the last sentence of this Section 6.9(c), each of the Sellers shall not, and shall cause each of their Affiliates not to, directly or indirectly, during the period commencing on the Closing Date and ending on the second anniversary of the Closing Date engage in, or own, manage, operate, control or participate in the management, operation or control of, or have any controlling interest, financial or otherwise, in (collectively, “Engage In”) the conduct of any business that is a Competitive Business. For purposes of this Section 6.9(c), the term “Competitive Business” shall mean the business engaged in by the Partnership Companies as it exists immediately after the Closing, including without limitation the business of gathering, treating, processing, storing, transporting and selling natural gas and transporting, fractionating and selling natural gas liquids. The restrictions contained in this Section 6.9(c) shall be limited to the Texas and New Mexico counties in which the Partnership Companies’ physical properties and assets are located as of the Closing Date together with any counties that are adjacent thereto (the “Non-Compete Area”). For purposes hereof, “control” of a Person means the ownership of more than 50% of the equity of such Person or the power to exercise more than 50% of the general voting rights of such Person. Notwithstanding anything to the

contrary contained in this Section 6.9(c), nothing in this Section 6.9(c) shall be deemed to prohibit the continued business and operations of Xxx Xxxxxxxxxx Carbon, Ltd., Xxxxxxxxxx Fuels, Inc. and Bass Enterprises Production Co. as currently conducted.

Section 6.10 Books and Records. From and after the Closing:

(a) Sellers and their respective Affiliates may retain a copy of all of the data room materials and other books and records (other than Tax records which are addressed in Article VII) relating to the business or operations of the Partnership Companies on or before the Closing Date. Notwithstanding the foregoing, and in addition to the provisions of Article VII, Sellers and their respective Affiliates shall be entitled to retain originals of (i) any Tax Return covering a taxable period ending on or prior to the Closing Date and (ii) any Benefit Plan documentation. Sellers and their respective Affiliates shall provide Buyers with reasonable access, during normal business hours and upon reasonable prior notice, to any original books and records that remain in the possession of Sellers and their respective Affiliates which relate primarily to the business or operations of the Partnership Companies on or before the Closing Date and are reasonably required by Buyers in connection with the business and operations of the Partnership Companies, copies of which books and records are not in the possession of Buyers or their Affiliates. Sellers and their respective Affiliates shall cooperate with and provide reasonable assistance to Buyers in connection with their accessing of such books and records.

(b) Buyers shall preserve and keep a copy of all data room materials and all books and records (other than Tax records which are addressed in Article VII) relating to the business or operations of the Partnership Companies on or before the Closing Date in Buyers’ possession for a period of at least seven years after the Closing Date.

Section 6.11 Permits. The Partnership Companies shall provide all notices and otherwise take all actions required to transfer or reissue any Permits, including those required under Environmental Laws, as a result of or in furtherance of the transactions contemplated by this Agreement. Buyers and Sellers shall use Reasonable Efforts to cooperate with the Partnership Companies to provide information necessary to apply for such Permits.

Section 6.12 Insurance.

(a) With the exception of the crime and pollution and remediation coverages, all Policies listed in Schedule 4.14 are written on an occurrence basis. Claims covered by the occurrence based Policies, occurring before the Closing Date, will be reported into these occurrence forms. Because the occurrence Policies are shared with entities not involved in the transactions contemplated by this Agreement, and therefore cannot be transferred to Buyers, coverage for occurrences after the Closing shall be obtained by Buyers under separate policies. Claims arising under the crime and pollution and remediation Policies shall be governed by the applicable policy terms and conditions.

(b) After the Closing, Buyers and the Partnership Companies shall be responsible for, and neither Sellers nor their Affiliates shall have any responsibility for, the payment of any deductible amounts attributable to the Policies specified in subsection (a) above and the predecessor policies arising from the operations of the Partnership Companies. Buyers acknowledge that certain of the Policies require Sellers or their respective Affiliates to provide an indemnity to the insurance carrier for deductible amounts and to provide collateral to secure such indemnity obligations. Buyers and Sellers will cooperate and use Reasonable Efforts to cause Buyers to be substituted for Sellers or any of their respective Affiliates (as applicable) with respect to such indemnities and to have such collateral replaced with a letter of credit or other adequate collateral from Buyers. Sellers shall indemnify and hold harmless Buyers for any and all charges made against such collateral or indemnification payments required to be paid by Buyers in connection with claims arising or alleged to arise from the operations of any entity other than the Partnership Companies. In the event that such substitution of indemnitor and collateral cannot be accomplished prior to the Closing, Buyers shall enter into an indemnification agreement in form mutually acceptable to Buyers and Sellers wherein Buyers agree to indemnify and hold harmless Sellers or any of their respective Affiliates (as applicable) for any and all of the costs of maintaining such collateral and for any charges made against such collateral or indemnification payments in connection with claims arising or alleged to arise from the operations of the Partnership Companies required to be paid by Sellers or any of their respective Affiliates (as applicable) under or with respect to such Policies from and after the Closing Date.

(c) If, at any time after the date hereof, Sellers or any of their respective Affiliates are entitled to receive proceeds under the Policies or receive any notices or proceeds under the Policies which are related to the business of the Partnership Companies, Sellers shall (and shall cause their Affiliates to) (i) use Reasonable Efforts to collect any such Proceeds from the insurance carrier and accept and hold such proceeds and notices for the account and sole benefit of Buyers, (ii) have no equitable or beneficial interest in such proceeds and notices and (iii) deliver such proceeds and notices (free of any withholding, setoff, recoupment, or deduction of any kind except as required by Law) promptly to Buyers in the same form received.

Section 6.13 Further Assurances. Upon the request of any Party at any time after the Closing Date, the other Parties will promptly execute and deliver such further instruments of assignment, transfer, conveyance, endorsement, direction or authorization and other documents as the requesting Party or its counsel may reasonably request to perfect title of Buyers and their successors and assigns to the Purchased Interests or otherwise to effectuate the purposes of this Agreement.

Section 6.14 Exclusivity. From the date of this Agreement through the Closing Date, Sellers will not (and Sellers will not permit the Partnership Companies or any of their officers, partners, directors, managers or advisors to), directly or indirectly, solicit, initiate, encourage, negotiate with, engage in discussions with, accept any proposal or offers from, or provide any information or access to any Person relating to the acquisition of all or substantially all of the equity securities or assets of the

Partnership Companies by such Person (including any acquisition structured as a merger, consolidation, or share exchange).

Section 6.15 Release Related to Due Diligence Activities. BUYERS HEREBY RELEASE AND AGREE TO INDEMNIFY, DEFEND, SAVE AND HOLD HARMLESS THE SELLER INDEMNIFIED PARTIES (AS HEREAFTER DEFINED) FROM ANY CLAIM ARISING OUT OF OR RELATED TO DUE DILIGENCE ACTIVITIES BY OR ON BEHALF OF BUYERS, INCLUDING DUE DILIGENCE ACTIVITIES CONDUCTED PURSUANT TO SECTION 6.2 OF THIS AGREEMENT ; PROVIDED, HOWEVER, THAT BUYERS SHALL NOT BE LIABLE TO THE SELLER INDEMNIFIED PARTIES FOR ANY ACT OR OMISSION OF SELLERS, THE PARTNERSHIP COMPANIES OR ANY OF THEIR RESPECTIVE EMPLOYEES OR AGENTS IN CONNECTION WITH ANY DUE DILIGENCE ACTIVITIES BY OR ON BEHALF OF BUYERS. THE OBLIGATIONS OF BUYERS UNDER THIS SECTION 6.15 SHALL NOT BE SUBJECT TO THE CONDITIONS AND LIMITATIONS SET FORTH IN ARTICLE IX HEREOF.

Section 6.16 Identification of Transferred Employees.

(a) Schedule 6.16(a) identifies each Active Employee as of the date of this Agreement (other than Non-Transferred Employees, as such term is defined in Section 6.16(b)), together with the Employee’s title or job position, work location, service, compensation and maximum amount of severance liability if such Employee were not to be retained for the Continuation Period in a manner complying with Section 6.17(c). Schedule 6.16(a) shall be updated by Sellers on or before the Closing Date to identify individuals who become Active Employees after the date of this Agreement (and who are not otherwise identified on an updated schedule), to remove those individuals who cease to be Active Employees prior to the Closing (without regard to the reason or circumstance for such termination of Active Employee status) and to identify any other changes in the information listed thereon.

(c) Schedule 6.16(c) identifies each other non-Partnership Company employee of Sellers or their other Affiliates who principally provides services in connection with the

Partnership Companies (hereinafter collectively referred to as “Other Employees”) and who would be an Active Employee if he or she were employed by any of the Partnership Companies, together with such employee’s title or job position, work location, service, compensation and maximum amount of severance liability if such employee were not to be retained for the Continuation Period in a manner complying with Section 6.17(c).

(a) Buyers shall cause all Employees listed in Schedule 6.16(a) to remain employed by the Partnership Companies as of the Closing Date in the same or comparable positions, and with at least the same base pay as was in effect immediately prior to the Closing Date (subject to Section 6.1(iii)). Such Employees, together with the Other Employees who meet the conditions for employment with Buyers or their Affiliates on and after the Closing Date as described in Section 6.17(b), are hereinafter collectively referred to as the “Transferred Employees.”

(b) On or before the Closing Date, but effective as of the Closing Date, Buyers or their Affiliates shall make offers of employment to each Other Employee who they desire to employ. The terms and conditions of each such offer of employment shall be on the terms and conditions determined by Buyers in their sole discretion; provided, that, the Buyers shall cause the Other Employees who become employed by a Partnership Company or another Affiliate of Buyers as of the Closing Date to be employed in the same or comparable positions, and with at least the same base pay as was in effect immediately prior to the Closing Date. For purposes of this Section, with respect to the compensation and benefits of the Other Employees between the date of this Agreement and the Closing Date, Sellers shall observe the covenants contained in Section 6.1(iii) as if the Other Employees were covered by such covenants. For an Other Employee to become an employee of Buyers or their Affiliates, the Other Employee must (i) accept Buyers’ or their Affiliates offer of employment under the terms and conditions provided in such offer, (ii) remain employed by the Sellers or any of their Affiliates until the Closing Date, and (iii) commence active employment with Buyers or their Affiliates immediately upon the Closing Date or such later date as otherwise agreed by Buyers. Sellers shall be responsible for all wages and benefits of Other Employees who become Transferred Employees for all periods prior to the Closing Date (or such later date as such employee commences employment with Buyers or their Affiliates, as agreed with Buyers).

(c) Except as provided in Section 6.17(f), this Section 6.17 shall not limit Buyers’ ability to change a Transferred Employee’s position, compensation or benefits for performance-related or other business reasons or require Buyers to continue the employment of a Transferred Employee for any particular period of time after the Closing; provided, however,

that in the event that (A) a Transferred Employee is terminated without Cause during the one year period following the Closing Date (the “Continuation Period”), (B) during the Continuation Period, Buyers fail to provide a Transferred Employee with a base compensation level at least as high as such Transferred Employee’s base compensation level (i.e., base hourly wages or base salary, as applicable) as of the day immediately preceding the Closing (subject to Section 6.1(iii)), or (C) during the Continuation Period, if a Transferred Employee resigns his employment with the Partnership Companies and their Affiliates after Buyers fail to provide such Transferred Employee with a principal place of work that is no more than 20 miles from such Transferred Employee’s place of work as of the day immediately preceding the Closing, then Buyers shall be responsible for and shall pay (or shall cause the Partnership Companies or another of their Affiliates to pay) the severance payment due to such Transferred Employee in accordance with the provisions of Sellers’ severance pay program reflected in the form of the April 4, 2005 communication to Employees provided to Buyers.

(e) On and after the Closing Date, Buyers shall cause the Partnership Companies to recognize the service of each Transferred Employee for Sellers and the Partnership Companies before the Closing Date for all employee benefit and employment-related purposes, except for benefit accrual under any defined benefit pension plan, whether non-qualified or subject to Title IV of ERISA.

(f) Sellers shall pay to Transferred Employees any quarterly bonus payments due to Transferred Employees for the full and partial quarterly periods prior to the Closing Date.

Section 6.20 Defined Benefit Plan, Deferred Compensation Plan and Defined Contribution Plans.

(a) Effective as of the Closing Date, benefit accruals under the Retirement Plan for Employees of Bass Enterprises Production Co. (the “Sellers’ Pension Plan”) shall cease as to all Transferred Employees (the “Eligible Transferred Employees”) and Sellers’ Pension Plan shall be amended to exclude all other employees of SRES, REM and Leapartners and their ERISA Affiliates from and after the Closing Date. Sellers shall cause Sellers’ Pension Plan to fully vest and make nonforfeitable all accrued benefits of the Transferred Employees under such Plan, effective as of the Closing Date. None of SRES, REM, Leapartners or their ERISA Affiliates from and after the Closing Date shall have any further funding obligation with respect to Sellers’ Pension Plan as of and following the Closing Date and Sellers shall indemnify and hold harmless Buyers, SRES, REM, Leapartners and their ERISA Affiliates from and after the Closing Date from any liability arising thereunder. Benefits shall be payable under Sellers’ Pension Plan in accordance with its terms, subject to the vesting and freezing of benefit accruals and eligibility subsequent to the Closing Date.

(b) Sellers or an identified ERISA Affiliate of the Sellers shall assume sponsorship of and all obligations under the Xxx Xxxxxxxxxx Energy Restoration Plan and the Xxxxxxxxxx Energy Marketing Restoration Plan (collectively, the “SRCG Restoration Plan”) effective as of the Closing Date.

Buyers’ 401(k) Plan until the receipt of reasonable evidence that Buyers’ 401(k) Plan is tax-qualified. In the event that Buyers’ do not intend to cover the Transferred Employees under Buyers’ 401(k) Plan, or no such plan exists, then SRES, REM and Leapartners shall consent to a “termination spinoff” of the portion of Sellers’ 401(k) Plan attributable to Transferred Employees, in which case the Transferred Employees with account balances in Sellers’ 401(k) Plan shall be entitled to a distribution in accordance with the terms of Sellers’ 401(k) Plan.

If the employment of an Employee of SRES, REM, or Leapartners is terminated by reason of the transactions contemplated hereby on the Closing Date, then Sellers or their ERISA Affiliates shall provide health continuation coverage under COBRA (or an election for such coverage, as applicable) through the period of required coverage under a health plan of Sellers or their ERISA Affiliates for such Employee and all Qualified Beneficiaries with respect to such Employee in accordance with COBRA.

On or after the Closing Date, Buyers and their Affiliates shall allow Transferred Employees to receive paid time off for any unused vacation time (including personal days) specified on Schedule 6.22, as adjusted to reflect actual vacation through the Closing Date. Except as required otherwise by applicable Laws, Sellers and their Affiliates shall have no liability to Transferred Employees for the vacation payments described in the immediately preceding sentence. Notwithstanding Buyers’ obligations set forth in this Section 6.22, nothing in this Section 6.22 shall obligate Buyers to maintain the Partnership Companies’ vacation plans in effect at the Closing.

Section 6.23 No Third Party Beneficiaries. Nothing expressed or implied in Section 6.16 through Section 6.22 shall confer upon any employee of Sellers or their Affiliates (including but not limited to the Partnership Companies), or Buyers or their Affiliates, or upon any legal representative of any such employees, any rights or remedies, including any right to employment or continued

employment for any specified period, of any nature or kind whatsoever under or by reason of this Agreement. Nothing in this Agreement, express or implied, shall create a third party beneficiary relationship or otherwise confer any benefit, entitlement, or right upon any person or entity other than the parties hereto. Nothing in this Agreement shall cause Buyers or their Affiliates or Sellers or their Affiliates to have any obligation to provide employment or any employee benefits to any individual who is not a Transferred Employee.

Section 6.24 Plan Terms Controlling. Nothing in this Agreement shall be deemed to confer upon any Person (or any beneficiary thereof) any rights under or with respect to any plan, program, or arrangement described in or contemplated by Section 6.16 through Section 6.22, and each Person (and any beneficiary thereof) shall be entitled to look only to the express terms of any such plan, program, or arrangement for his or her rights thereunder.

Section 6.25 WARN Act Requirements. On and after the Closing Date, Buyers and the Partnership Companies shall be responsible with respect to Transferred Employees and their beneficiaries for compliance, if required, with The Worker Adjustment and Retraining Notification Act of 1988 and any other similar, applicable law (the “Warn Act”), including any requirement to provide for and discharge any and all notifications, benefits, and liabilities to Transferred Employees and government agencies that might be imposed as a result of the consummation of the transactions contemplated by this Agreement or otherwise. On and after the Closing Date, Sellers shall retain all liabilities and obligations with respect to the WARN Act for all employees of Sellers and their Affiliates and their beneficiaries other than Transferred Employees.

Section 6.26 Successors and Assigns. In the event Buyers or any of their successors and assigns (a) consolidate with or merge into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger or (b) transfer all or substantially all of their assets to any Person, then, and in each case, proper provision shall be made so that such successors and assigns of Buyers honor the obligations of Buyers and their Affiliates set forth in Section 6.16 through Section 6.26.

Section 6.27 Financial Statements. The Sellers shall provide Buyers access to Sellers’ personnel, books and records to the extent reasonably necessary to enable Buyers to prepare financial statements of the Partnership Companies in such form and covering such periods as may be required by any applicable securities laws to be filed with the Securities and Exchange Commission by Buyers as a result of the transactions contemplated by this Agreement.

Section 6.28 Certain Contracts. To the extent, if any, that any contract rights, agreements, commitments or other arrangements relating to the business of the Partnership Companies exist and will not be, after the Closing Date, held of record by the Partnership Companies, Sellers (or their Affiliates) will hold such contract rights, agreements, commitments or other arrangements as nominee for and on behalf of Buyers and for Buyers’ sole account.

Section 6.29 Capital Expenditures. Sellers shall cause the Partnership Companies to make Capital Expenditures substantially in accordance with the Capital Expenditure Budget and, on or before the Closing Date, shall notify Buyers of any expected variance between actual capital expenditures and budgeted amounts.

ARTICLE VII

TAX MATTERS

Section 7.1 [Intentionally Omitted]

Section 7.2 Tax Returns.

(a) The income of the Partnership Companies will be apportioned to the period up to and including the Closing Date, and the period after the Closing Date by closing the books and records of the Partnership Companies as of 11:59 p.m. local time on the day immediately preceding the Closing Date.

(b) With respect to any Tax Return of a Partnership Company covering a taxable period ending on or before the Closing Date that is required to be filed after the Closing Date, Sellers shall cause such Tax Return to be prepared and shall cause to be included in such Tax Return all items required to be included therein. Not later than 30 days prior to the due date of each such Tax Return, Sellers shall deliver a copy of such Tax Return to Buyers together with a statement of the difference, if any, of the amount of Tax shown due on such Tax Return over the amount set up as a liability for such Tax in the Closing Statement. If the Tax shown on the Tax Return exceeds the amount set up as a liability for the Tax in the Closing Statement, not later than 5 days prior to the due date of such Tax Return, Sellers shall pay to Buyers the amount of such excess. If the amount set up as a liability for the Tax in the Closing Statement exceeds the Tax shown on the Tax Return, not later than 5 days prior to the due date of such Tax Return, Buyers shall pay to Sellers the amount of such excess. Buyers shall cause such Partnership Company to file such Tax Return and timely pay the Taxes shown due on such Tax Return.

(c) With respect to any Tax Return of a Partnership Company covering a taxable period beginning on or before the Closing Date and ending after the Closing Date (the “Straddle Period”) that is required to be filed after the Closing Date, Buyers shall cause such Straddle Period Tax Return to be prepared and shall cause to be included in such Straddle Period Tax Return all Tax items required to be included therein. Buyers shall determine the Tax which would have been due with respect to the Straddle Period if such Straddle Period ended on the Closing Date (the “Pre-Closing Date Tax”). Not later than 45 days prior to the due date of each such Straddle Period Tax Return, Buyers shall deliver a copy of the Straddle Period Tax Return to Sellers for their review. If Sellers agree with the Straddle Period Tax Return, Sellers shall pay to Buyers an amount equal to the excess, if any, of the Pre-Closing Date Tax over the amount set up as a liability for such Tax in the Closing Statement not later than 5 days prior to the due date

of the Straddle Period Tax Return. If, within 15 days of the receipt of the Straddle Period Tax Return, Sellers notify Buyers that they dispute the manner of preparation of the Straddle Period Tax Return or the amount of the Pre-Closing Date Tax, then Buyers and Sellers shall attempt to resolve their disagreement within the five-day period following Sellers’ notification to Buyers of such disagreement. If Buyers and Sellers are unable to resolve their disagreement, the dispute shall be submitted to a mutually agreed upon Accounting Firm, whose expense shall be borne equally by Buyers and Sellers, for resolution within 20 days of such submission. The decision of such accounting firm with respect to such dispute shall, absent manifest error, be binding upon Buyers and Sellers, and Sellers shall pay to Buyers an amount equal to the excess, if any, of the Pre-Closing Date Tax over the amount set up as a liability for such Tax in the Closing Statement as decided by such Accounting Firm not later than 5 days prior to the due date of the Straddle Period Tax Return. In the event of (i) any Tax Authority review of a Straddle Period Tax Return or (ii) any proposed audit, notice, proposed adjustment, assessment, claim, liability, or other potential tax proceeding relating to a Straddle Period Tax Return (each, a “Straddle Period Tax Claim”), Buyers and Sellers shall handle such review and/or Straddle Period Tax Claim on a joint basis and in a reasonable manner.

(d) Any Tax Return prepared pursuant to the provisions of this Section 7.2 shall be prepared in a manner consistent with practices followed in prior years with respect to similar Tax Returns, except as otherwise required by Law or fact.

(e) Because Treasury Regulations section 301.6109-(1)(d)(2)(iii) requires that Buyers retain the Employer Identification Number of each Partnership Company, the following shall apply for purposes of (i) Tax Authority reviews of any Partnership Company Tax Return covering a taxable period ending on or prior to the Closing Date and (ii) any Pre-Closing Date Period Tax Claim; provided, however, that in the event that (A) a Pre-Closing Date Period Tax Claim is also an Indemnified Tax Claim, the provisions of Section 7.4 shall control and (B) a Pre-Closing Date Period Tax Claim could result in Tax liability to Buyers that is not an Indemnified Tax Claim, such Pre-Closing Date Period Tax Claim shall be handled on a joint basis in a reasonable manner. Buyers shall promptly notify Sellers of any written or oral notice that any applicable Tax Authority has proposed a review of any Partnership Company Tax Return for taxable periods ending on or prior to the Closing Date, and Buyers shall promptly send to Sellers a copy of any written notice or other document received by Buyers from any Tax Authority with respect to any Partnership Company Tax Return covering a taxable period ending on or prior to the Closing Date. Sellers shall have the sole and exclusive right to control, handle, dispose of, and/or settle any and all proposed audits, notices, proposed adjustments, assessments, claims, liabilities, or other potential tax proceedings relating to a Tax Return of any Partnership Company covering a taxable period ending on or prior to the Closing Date (“Pre-Closing Date Period Tax Claims”), and Buyers shall execute or cause to be executed any and all documents and forms (including, without limitation, powers of attorney) necessary to enable Sellers to carry out the provisions of this Section 7.2(e). Sellers shall have the sole right, at Sellers' cost, to select counsel and other tax professionals for any Pre-Closing Date Period Tax Claim; provided, however, that Buyers may monitor any such Pre-Closing Date Period Tax Claim and shall pay for any costs associated with such monitoring. Buyers and Sellers shall, and Buyers shall cause the Partnership Companies to, cooperate to the extent necessary to resolve any Pre-Closing Date Period Tax Claims. So long as Sellers have not agreed in writing to settle a Pre-Closing Date Period Tax Claim and a challenge of such Pre-Closing Date Period Tax Claim can continue (by

any available means), neither Buyers, the Partnership Companies nor any of their respective representatives shall consent or otherwise agree to any element relating to such Pre-Closing Date Period Tax Claim. All positions taken herein by Sellers, Buyers and the Partnership Companies shall be in good faith.

(f) Buyers and Sellers shall cooperate fully, and Buyers shall cause each of the Partnership Companies to cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the preparation and filing of Tax Returns pursuant to this Section 7.2, any audit, litigation or other proceeding (each, a “Tax Proceeding”) with respect to Taxes and any Pre-Closing Date Period Tax Claims. Such cooperation shall include access to, the retention and (upon the other Party’s request) the provision of records and information which are reasonably relevant to any such Tax Return, Tax Proceeding or Pre-Closing Date Period Tax Claim, and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Sellers will, and Buyers will and will cause the Partnership Companies to, retain all books and records with respect to Tax matters pertinent to the Partnership Companies relating to any taxable period beginning before the Closing Date until the earlier of six years after the Closing Date or the expiration of the applicable statute of limitations of the respective taxable periods, and to abide by all record retention agreements entered into with any Tax Authority. Buyers and Sellers each agree, upon request, to use Reasonable Efforts to obtain any certificate or other document from any Tax Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed with respect to the transactions contemplated by this Agreement.

(g) From and after the Closing Date, Buyers and their respective Affiliates (including the Partnership Companies) will not file any amended Tax Return or other adjustment request with respect to the Partnership Companies for taxable periods ending on or prior to the Closing Date without the prior written consent of Sellers.

(h) Subject to the second sentence of this Section 7.2(h), Tax refunds of any kind relating to any taxable period ending (or treated as ending) on or prior to the Closing Date shall inure to the benefit of Sellers, and Buyers shall pay the full amount of any such refund (including interest thereon), net of any tax liability related to the receipt of such refund, to Sellers promptly upon receipt of such refund by Buyers. Buyers shall be entitled to any Tax refunds resulting from the carryback of any loss or credit arising in a taxable period beginning on or after the Closing Date except for Tax refunds for which Buyers were given credit as a reduction in Purchase Price to which Sellers shall be entitled.

(i) At least 30 days prior to the Closing, Sellers (or, at Buyers’ option, Buyers) shall prepare and deliver to the other Parties an allocation (the “Allocation”) of the Purchase Price (and all other capitalized costs) among the Assets of the Partnership Companies in accordance with Treasury Regulations section 1.755 - 1 (and any similar provision of state, local or foreign law, as appropriate). Within 45 days after the date the Purchase Price is finally determined pursuant to Section 2.5 hereof, Sellers and Buyers shall use their best efforts to agree to the final Allocation. If the Parties agree to such Allocation, as contemplated by the foregoing sentence, such Allocation shall be binding upon Sellers and Buyers. Further, Sellers, Buyers and their respective Affiliates shall then report, act, and file Tax Returns in all respects

and for all purposes consistent with the Allocation and shall not take any position (whether in audits, Tax Returns or otherwise) that is inconsistent with the Allocation unless required to do so by applicable law. Buyers shall timely and properly prepare, execute, file and deliver all such documents, forms and other information as Sellers may reasonably request in their preparation of the Allocation.

Section 7.3 Transfer Taxes. Buyers shall be responsible for and indemnify Sellers for the payment of all state and local transfer, sales, use, stamp, registration or other similar Taxes resulting from the transactions contemplated by this Agreement.

Section 7.4 Tax Indemnity.

(a) Sellers shall be solely liable for, shall pay and shall protect, defend, indemnify and hold harmless (x) Buyers and any Person holding a direct or indirect interest in either Buyer that is required to include for Tax purposes on its Tax Return all or a portion of the income, gain, loss, deduction or credit of the Partnership Companies or the Buyers, and (y) the Partnership Companies from any and all Losses attributable to (i) any breach of any representation or warranty made by Sellers in Section 4.10 or any covenants and agreements made by Sellers in this Article VII and (ii) Taxes in excess of any liability for Taxes reflected on the Closing Statement which relate to or result from the income, business, property, status or operations of a Partnership Company prior to or on the Closing Date, or for which a Partnership Company is liable with respect to such period (whether pursuant to Treasury Regulations section 1.1502-6 or any similar state, local or foreign law or regulation, as a transferee or successor, by contract or otherwise). Buyers shall be solely liable for, shall pay and shall protect, defend, indemnify and hold harmless Sellers from any and all Taxes which relate to or result from the income, business, property, status or operations of the Partnership Companies after the Closing Date.

(b) If any claim (an “Indemnified Tax Claim”) is made by any Tax Authority that, if successful, would result in indemnification of any Party (the “Tax Indemnified Party”) or its Affiliate by another Party (the “Tax Indemnifying Party”) under this Section 7.4, the Tax Indemnified Party shall promptly, but in no event later than the earlier of (i) 45 days after receipt of notice from the Tax Authority of such claim or (ii) 15 days prior to the date required for the filing of any protest of such claim, notify the Tax Indemnifying Party in writing of such fact; provided, however, that the failure of the Tax Indemnified Party to so notify the Tax Indemnifying Party shall not relieve the Tax Indemnifying Party of its obligations hereunder, unless and only to the extent that such failure to notify prejudices the Tax Indemnifying Party.

(c) The Tax Indemnifying Party shall control all decisions with respect to any Tax Proceeding involving an Indemnified Tax Claim and the Tax Indemnified Party shall take such action (including settlement with respect to such Tax Proceeding or the prosecution of such Tax Proceeding to a determination in a court or other tribunal of initial or appellate jurisdiction) in connection with a Tax Proceeding involving an Indemnified Tax Claim as the Tax Indemnifying Party shall reasonably request in writing from time to time, including with respect to the selection of counsel and experts and the execution of powers of attorney; provided, however, that (i) within 30 days after the notice required by Section 7.4(b) has been

delivered (or such earlier date that any payment of Taxes with respect to such claim is due but in no event sooner than five days after the Tax Indemnifying Party’s receipt of such notice), the Tax Indemnifying Party requests that such claim be contested and (ii) if the Tax Indemnified Party is requested by the Tax Indemnifying Party to pay the Tax claimed and xxx for a refund, the Tax Indemnifying Party shall have advanced to the Tax Indemnified Party, on an interest-free basis, the amount of such claim. The Tax Indemnified Party shall not make any payment of an Indemnified Tax Claim for at least 30 days (or such shorter period as may be required by applicable law) after the giving of the notice required by Section 7.4(b) with respect to such claim, shall give to the Tax Indemnifying Party any information requested related to such claim, and otherwise shall cooperate with the Tax Indemnifying Party in order to contest effectively any such claim. Notwithstanding the foregoing, the Parties shall jointly control all decisions with respect to any Tax Proceeding which, in the event of an adverse determination, may result in each Party having responsibility for an amount of Taxes hereunder.

(d) No claim for indemnity for any Losses or Taxes relating to any single Tax Return or any single item or group of related items shall be permitted pursuant to this Section 7.4 if such claim is for less than $10,000.

Section 7.5 Scope. Notwithstanding anything to the contrary herein, this Article VII shall be the exclusive remedy for any claims relating to Taxes (including any claims relating to representations and warranties respecting Tax matters). The rights hereunder relating to Taxes shall survive the Closing until 30 days after the expiration of the statute of limitations (including extensions) applicable to such Tax matter. No claim may be made or brought by any Party hereto after the expiration of the applicable survival period unless such claim has been asserted by written notice specifying the details supporting the claim on or prior to the expiration of the applicable survival period.

ARTICLE IX

INDEMNIFICATION

Section 9.1 Survival. The representations and warranties of the Parties contained in this Agreement or in any certificates or other writing delivered pursuant to this Agreement or in connection with this Agreement will survive the Closing for a period of twelve months following the Closing Date; provided, however, that (a) the representations and warranties contained in Sections 3.2, 3.5, 3.6, 4.9, 5.2 and 5.5 will survive the Closing indefinitely, (b) the representations and warranties contained in Section 4.10 will survive the Closing in accordance with the provisions of Article VII

Unless otherwise expressly provided herein, all covenants, agreements and obligations made by any party hereunder which are to be performed on or prior to the Closing Date shall expire at the Closing, and all covenants, agreements and obligations made by any party hereunder which are to be performed after the Closing Date shall survive in accordance with their terms until the applicable statute of limitations therefor has expired with respect to any breach thereof. Any right of indemnification or reimbursement pursuant to this Article IX with respect to a claimed breach, inaccuracy or non-fulfillment of any representation, warranty, covenant, agreement or obligation shall expire on the applicable date of termination of the representation, warranty, covenant, agreement or obligation claimed to be breached as set forth in Section 9.2(a) or 9.2(b) (provided, however, that a Party may make a claim for indemnification for a breach of any covenant that expires on the Closing Date until one year after the Closing Date) (the “Expiration Date”), unless on or prior to the applicable Expiration Date, the Indemnifying Party has received written notice from the Indemnified Party of such breach, inaccuracy or non-fulfillment, in which case the Indemnified Party may continue to pursue its right of indemnification or reimbursement hereunder beyond the Expiration Date of the applicable representation, warranty, covenant, agreement or obligation.

Section 9.2 Indemnification.

(a) Subject to the provisions of this Article IX (including, without limitation, the provisions of Section 9.4 hereof), from and after the Closing, Sellers shall indemnify, defend and hold harmless Buyers, Buyers’ Affiliates (including the Partnership Companies from and after the Closing) and their respective Representatives and their respective successors and permitted assigns (the “Buyer Indemnified Parties”) from and against all Losses incurred or suffered by them as a result of, relating to or arising out of (i) any breach of or any inaccuracy in any representation or warranty of Sellers contained in Sections 3.2 or 3.6 of this Agreement as of the date hereof or as of the Closing Date or in any certificates delivered pursuant to or in connection with this Agreement, (ii) any breach of or any inaccuracy in any representation or warranty of Sellers contained in Article III (other than Sections 3.2 or 3.6) or Article IV of this Agreement as of the date hereof or as of the Closing Date, (iii) any breach of or failure by Sellers to perform any covenant or obligation of Sellers contained in this Agreement, and (iv) assets or lines of business that have been sold, transferred, relinquished or abandoned by the Partnership Companies, including assets that have reverted to landowner ownership, as of the Closing Date. For purposes of Section 9.2(a)(ii), in determining whether the Sellers have breached any of their representations and warranties contained in Article III or IV, all qualifications of such representations and warranties by materiality (whether by reference to the terms “material,”“Material Adverse Effect” or any threshold amount or otherwise) shall be disregarded.

(b) Subject to the provisions of this Article IX, from and after the Closing, Buyers shall indemnify, defend and hold harmless Sellers, their respective Affiliates, their respective Representatives and their respective permitted successors and assigns (the “Seller Indemnified Parties”) from and against all Losses incurred or suffered by them as a result of, relating to or

arising out of (i) any breach of or any inaccuracy in any representation or warranty of Buyers contained in this Agreement as of the date hereof or as of the Closing Date or in any certificates delivered pursuant to or in connection with this Agreement, (ii) any breach of or failure by Buyers to perform any covenant or obligation of Buyers contained in this Agreement and (iii) the businesses and operations of the Partnership Companies (whether relating to periods prior to or after the Closing Date) to the extent such Losses (A) arise out of a matter for which a Partnership Company has liability, (B) are not subject to the provisions of Section 9.2(a) hereof or any other provision of this Agreement that requires the Sellers to assume such liability or indemnify Buyers or the Partnership Companies for such liability and (C) are not the subject of a written notice delivered by the Buyer Indemnified Parties in accordance with, and by the date specified in, Section 9.1.

Section 9.3 Indemnification Procedures. Claims for indemnification under this Agreement (other than claims involving a Tax Proceeding, the procedures for which are set forth in Article VII) shall be asserted and resolved as follows:

(a) If any Person who or which is entitled to seek indemnification under Section 9.2 (an “Indemnified Party”) receives notice of the assertion or commencement of any claim, demand, action, suit or proceeding made or brought by any third party (a “Third Party Claim”) against such Indemnified Party with respect to which the Person against whom or which such indemnification is being sought (an “Indemnifying Party”) is obligated to provide indemnification under this Agreement, the Indemnified Party will give such Indemnifying Party reasonably prompt written notice thereof, but in any event not later than 30 days after receipt of such written notice of such Third Party Claim. Such notice by the Indemnified Party will describe the Third Party Claim in reasonable detail, will include copies of all available material written evidence thereof and will indicate the estimated amount, if reasonably practicable, of the Losses that have been or may be sustained by the Indemnified Party. The Indemnifying Party will have the right to participate in, or, by giving written notice to the Indemnified Party, to assume, the defense of any Third Party Claim at such Indemnifying Party’s own expense and by such Indemnifying Party’s own counsel (reasonably satisfactory to the Indemnified Party), and the Indemnified Party will cooperate in good faith in such defense.

(b) If, within 10 days after giving notice of a Third Party Claim to an Indemnifying Party pursuant to Section 9.3(a), an Indemnified Party receives written notice from the Indemnifying Party that the Indemnifying Party has elected to assume the defense of such Third Party Claim as provided in the last sentence of Section 9.3(a), the Indemnifying Party will not be liable for any legal expenses subsequently incurred by the Indemnified Party in connection with the defense thereof; provided, however, that (i) if the Indemnifying Party fails to take reasonable steps necessary to defend diligently such Third Party Claim within 10 days after receiving written notice from the Indemnified Party that the Indemnified Party believes the Indemnifying Party has failed to take such steps or if the Indemnifying Party has not undertaken fully to indemnify the Indemnified Party in respect of all Losses relating to the matter, the Indemnified Party may assume its own defense, and the Indemnifying Party will be liable for all

reasonable costs and expenses paid or incurred in connection therewith and (ii) the Indemnified Party may employ separate counsel, and the Indemnifying Party will bear the expenses of such separate counsel, if in the written opinion of counsel to the Indemnified Party use of counsel of the Indemnifying Party’s choice would be expected to give rise to a conflict of interest. Without the prior written consent of the Indemnified Party, the Indemnifying Party will not enter into any settlement of any Third Party Claim that would lead to loss, liability or create any financial or other obligation on the part of the Indemnified Party for which the Indemnified Party is not entitled to indemnification hereunder, or which provides for injunctive or other non-monetary relief applicable to the Indemnified Party, or does not include an unconditional release of all Indemnified Parties.

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

(d) A failure to give timely notice or to include any specified information in any notice as provided in Section 9.3(a), 9.3(b) or 9.3(c) will not affect the rights or obligations of any party hereunder, except and only to the extent that, as a result of such failure, any party that was entitled to receive such notice was materially prejudiced as a result of such failure.

(e) Notwithstanding anything contained herein to the contrary, the amount of any Losses incurred or suffered by any Indemnified Person shall be calculated after giving effect to (i) any insurance proceeds (net of any premiums paid or costs incurred in connection therewith) received by the Indemnified Person (or any of its Affiliates) with respect to such Losses, (ii) any net Tax Benefit actually and currently realized by the Indemnified Person (or any of its Affiliates) arising from the facts or circumstances giving rise to such Losses and (iii) any indemnification or reimbursement payments or other recoveries obtained by the Indemnified Person (or any of its Affiliates) from any other third party with respect to such Losses. Each Indemnified Person shall exercise Reasonable Efforts to obtain such proceeds, benefits, payments and recoveries. If any such proceeds, benefits, payments or recoveries are received by an Indemnified Person (or any of its Affiliates) with respect to any Losses after an Indemnifying Person has made a payment to the Indemnified Person with respect thereto, the Indemnified Person (or such Affiliate) shall pay to the Indemnifying Person the amount of such proceeds, benefits, payments or recoveries (up to the amount of the Indemnifying Person's

payment). An indemnified party shall use reasonable efforts to mitigate damages in respect of any claim for which it is seeking indemnification.

(f) Upon making any payment to an Indemnified Person in respect of any Losses, the Indemnifying Person will, to the extent of such payment, be subrogated to all rights of the Indemnified Person (and its Affiliates) against any third party in respect of the Losses to which such payment relates. Such Indemnified Person (and its Affiliates) and Indemnifying Person will execute upon request all instruments reasonably necessary to evidence or further perfect such subrogation rights.

(g) In the event an Indemnified Party shall recover Losses in respect of a claim of indemnification under this Article IX, no other Indemnified Party shall be entitled to recover the same Losses in respect of a claim for indemnification.

Section 9.4 Limitations on Liability of Sellers. Notwithstanding anything to the contrary herein, Sellers’ obligations to indemnify the Buyer Indemnified Parties pursuant to Section 9.2(a)(ii) hereof shall be subject to the following limitations:

(a) A breach of any representation, warranty or covenant of Sellers in this Agreement in connection with any single item or group of related items that results in Losses of less than $100,000 shall be deemed, for all purposes of this Article IX, not to be a breach of such representation, warranty or covenant, and therefore shall not be applied towards the Threshold Amount or be indemnifiable hereunder.

(b) Sellers shall have no liability arising out of or relating to Section 9.2(a)(ii) until the aggregate amount of all such Losses actually incurred by the Buyer Indemnified Parties thereunder exceeds an amount equal to 1% of the Purchase Price (the “Threshold Amount”), in which event Sellers’ indemnity obligations shall apply to Losses actually incurred in excess of the Threshold Amount (subject to the maximum liability provided for in subsection (c) below); provided, however, that in respect of Losses incurred or suffered by the Buyer Indemnified Parties as a result of, relating to or arising out of any breach of the representations and warranties contained in Section 4.11, the Threshold Amount shall be deemed to be $5,000,000.

(c) In no event shall Sellers’ aggregate liability arising out of or relating to Section 9.2(a)(ii) exceed 10% of the Purchase Price (the “Cap Amount”), and each Buyer Indemnified Party waives and releases and shall have no recourse against Sellers pursuant to Section 9.2(a)(ii) in excess of such Cap Amount.

(d) No Buyer Indemnified Party shall be entitled to indemnification under Section 9.2(a)(ii) to the extent Buyers have otherwise been compensated by reasons of adjustments (pursuant to Section 2.5) in the calculation of the Purchase Price relative to what it would have been absent such Loss.

Section 9.5 Waiver of Other Representations.

(a) NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, IT IS THE EXPLICIT INTENT OF EACH PARTY HERETO, AND THE PARTIES HEREBY AGREE, THAT NONE OF THE SELLERS OR ANY OF THEIR RESPECTIVE AFFILIATES OR REPRESENTATIVES HAS MADE OR IS MAKING ANY REPRESENTATION OR WARRANTY WHATSOEVER, EXPRESS OR IMPLIED, WRITTEN OR ORAL, INCLUDING ANY IMPLIED REPRESENTATION OR WARRANTY AS TO THE CONDITION, MERCHANTABILITY, USAGE, SUITABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE WITH RESPECT TO THE PURCHASED INTERESTS, THE PARTNERSHIP COMPANIES, THEIR ASSETS, OR ANY PART THEREOF, EXCEPT THOSE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, AND WITHOUT IN ANY WAY LIMITING THE FOREGOING, SELLERS MAKE NO REPRESENTATION OR WARRANTY TO BUYERS WITH RESPECT TO ANY FINANCIAL PROJECTIONS OR FORECASTS RELATING TO THE PARTNERSHIP COMPANIES.

(b) EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN, SELLERS’ INTERESTS IN THE PARTNERSHIP COMPANIES AND THEIR ASSETS ARE BEING TRANSFERRED THROUGH THE SALE OF THE PURCHASED INTERESTS “AS IS, WHERE IS, WITH ALL FAULTS,” AND, EXCEPT AS OTHERWISE EXPRESSLY PROVIDED HEREIN, SELLERS EXPRESSLY DISCLAIM ANY REPRESENTATIONS OR WARRANTIES OF ANY KIND OR NATURE, EXPRESS OR IMPLIED, AS TO THE CONDITION, VALUE OR QUALITY OF THE PARTNERSHIP COMPANIES AND THEIR ASSETS OR THE PROSPECTS (FINANCIAL OR OTHERWISE), RISKS AND OTHER INCIDENTS OF THE PARTNERSHIP COMPANIES AND THEIR ASSETS.

(c) Buyers acknowledge and agree that none of Sellers, their Affiliates, any of their Representatives and any other Person has made any representation or warranty, express or implied, as to the accuracy or completeness of any memoranda, charts, summaries or schedules heretofore made available by Sellers, their Affiliates or their Representatives to Buyers, any of their Affiliates or their Representatives (including, without limitation, the Executive Summary dated May 2005 prepared by Xxxxxx Brothers, Inc.) or any information that is not included in this Agreement or the Disclosure Schedule, and none of Sellers, their Affiliates, any of their Representatives nor any other Person will have or be subject to any liability to Buyers, any of their Affiliates or their Representatives resulting from the distribution of any such information to, or the use of any such information by, Buyers, any of their Affiliates or any of their agents, consultants, accountants, counsel or other Representatives.

(d) The representations and warranties contained in Section 4.11 shall be the exclusive representations and warranties with regard to Environmental Laws and related matters.

Section 9.6 Purchase Price Adjustment. The Parties agree to treat all payments made pursuant to this Article IX as adjustments to the Purchase Price for Tax purposes.

Section 9.7 Exclusive Remedy. Except for the indemnification provisions set forth in Article VII hereof, the right of indemnification set forth in this Article IX (subject to all limitations provided for herein) shall be the sole and exclusive remedy of the Parties and all Indemnified Parties under or by reason of this Agreement (including for any breach of any representation, warranty, covenant or agreement set forth in this Agreement) and each Party covenants and agrees not to seek or assert any other remedy following the Closing; provided, however, that the foregoing shall not limit the right of any Party to seek any equitable remedy available to enforce the rights of such Party under this Agreement.

Section 9.8 Waiver of Consequential Damages. NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, NO PARTY SHALL BE LIABLE FOR PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE AND WHETHER OR NOT ARISING FROM ANY OTHER PARTY’S SOLE, JOINT OR CONCURRENT NEGLIGENCE, STRICT LIABILITY OR OTHER FAULT.

Section 9.9 Tax Indemnity. Notwithstanding anything in this Article IX to the contrary, all Losses relating to Taxes which are the subject of Article VII shall only be subject to indemnification under Article VII.

Section 9.10 Security. Until the third anniversary of the Closing Date, Sellers shall provide security to Buyers in the form of a letter of credit, in form and substance reasonably satisfactory to Buyers, in an initial amount equal to the Cap Amount (such amount to be reduced by the amount of any payments made by Sellers in respect of their indemnification obligations under this Article IX) for the purpose of satisfying claims by Buyers for indemnification under this Article IX. After such third anniversary, in the event that Buyers shall have submitted to Sellers, prior to such third anniversary, written notice of a claimed breach, inaccuracy or non-fulfillment of any representation, warranty, covenant, agreement or obligation, Sellers shall provide such further security to Buyers (in the form of a bond, letter of credit or other means reasonably acceptable to Buyers) in an amount equal to the lesser of the Cap Amount and the amount of the Loss in question.

ARTICLE X

TERMINATION

Section 10.1 Termination. At any time prior to the Closing, this Agreement may be terminated and the transactions contemplated hereby abandoned:

(a) by the mutual consent of Buyers and Sellers as evidenced in writing signed by each of Buyers and Sellers;

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

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

(d) by either Buyers or Sellers if any Governmental Authority having competent jurisdiction has issued a final, non-appealable order, decree, ruling or injunction (other than a temporary restraining order) or taken any other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement; or

(e) by either Buyers or Sellers, if the Closing has not occurred on or before March 1, 2006 (provided that if the Closing shall not have occurred by such date solely as a result of the conditions relating to the HSR Act set forth in either Section 8.1(a) or 8.2(a) not being satisfied, such date shall be extended to June 30, 2006), or such later date as the Parties may agree upon.

Section 10.2 Effect of Termination. In the event of the termination of this Agreement pursuant to Section 10.1, this Agreement, except for the provisions of Section 6.2(b), Section 6.15, this Section 10.2 and all of Article XI, shall become void and have no effect, without any liability on the part of any Party hereto or its directors, officers, managers, members or partners; provided, however, that (i) nothing in this Section 10.2 shall relieve any Party hereto of liability for a material breach of any of its obligations under this Agreement or a material breach of any of its representations and warranties hereunder and (ii) all filings, applications and other submissions made pursuant to this Agreement, to the extent practicable, shall be withdrawn from the agency or other Person to which they were made or appropriately amended to reflect the termination of the transactions contemplated hereby. If it shall be judicially determined that termination of this Agreement was caused by an intentional breach of this Agreement, then, in addition to other remedies at law or equity for breach of this Agreement, the Party so found to have intentionally breached this Agreement shall indemnify and hold harmless the other Parties hereto for their respective out-of-pocket costs, including the fees and expenses of their counsel, accountants, financial advisors and other experts and advisors, as well as fees and expenses incident to the negotiation, preparation and execution of this Agreement and related documentation. The Confidentiality Agreement shall not be affected by a termination of this Agreement.

or to such other address or addresses as a Party may from time to time designate by written notice to the other Parties in the manner in this Section 11.1. Notice by mail shall be deemed to have been duly given and received on the third day after posting. Notice by messenger, nationally recognized overnight courier service, facsimile transmission or personal delivery shall be deemed given on the date of actual delivery.

Section 11.2 Assignment.

(a) Except as set forth in Section 11.2(b), no Party may assign this Agreement or any part of its rights or obligations hereunder without the prior written consent of the other Parties. Any attempted assignment in violation of this Section 11.2 shall be null and void.

(b) Buyers shall have the right to structure this transaction so that it qualifies, in whole or in part, under the exchange provisions of Section 1031 of the Code. In the event Buyers elect to structure this transaction so that it qualifies under such provisions, Sellers shall cooperate with Buyers at no cost or liability to Sellers in connection with efforts to effect the exchange transaction, including any reasonable use of a “qualified intermediary” or an “exchange accommodation titleholder” within the meaning of the United States Treasury Regulations and related authority (collectively, the “Qualified Intermediary”). In order to

implement such structure, (i) Buyers may, upon written notice to Sellers, assign all or part of their rights under this Agreement to a third party designated by Buyers to act as a Qualified Intermediary; (ii) Sellers shall, and hereby agree to, acknowledge such assignment in writing and to accept payment of all or a portion of the Purchase Price from the Qualified Intermediary; and (iii) at Closing, Sellers shall convey the Purchased Interests directly to Buyers, Buyers' designee, or the Qualified Intermediary, as the case may be. Sellers shall have no responsibility or liability to Buyers or any other person for the qualification of Buyers' purported exchange transaction under Section 1031 of the Code. Sellers shall not be required to incur any additional expense or liability as a result of such cooperation, exchange or assignment. Buyers shall indemnify, defend and hold Sellers harmless from and against any and all claims, damages, liabilities, losses, costs and expenses, including, without limitation, court costs and reasonable attorneys’ fees and paralegals’ fees and disbursements, arising out of or in any way connected with the exchange that Sellers would not have incurred but for the exchange.

Section 11.3 Benefits of Agreement. All of the terms and provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Except for the provisions of Article IX, this Agreement is for the sole benefit of the parties hereto and not for the benefit of any third party.

Section 11.4 Expenses. Except as otherwise provided herein, each Party shall bear its own expenses incurred in connection with this Agreement and the transactions contemplated hereby whether or not such transactions shall be consummated, including all fees of its legal counsel, financial advisers and accountants.

Section 11.5 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Delivery of an executed counterpart of a signature page to this Agreement by facsimile or other electronic transmission shall be effective as delivery of a manually executed original counterpart of this Agreement.

Section 11.6 Entire Agreement. This Agreement (together with the Disclosure Schedule and any Exhibits hereto), the Confidentiality Agreement and all certificates, documents, instruments and writings that are delivered pursuant hereto constitute the entire understanding among the Parties with respect to the transactions contemplated hereby and supersede all prior arrangements, understandings and agreements, whether written or oral, relating to the subject matter of this Agreement and all prior drafts of this Agreement, all of which are merged into this Agreement.

Section 11.7 Disclosure Schedule. Unless the context otherwise requires, all capitalized terms used in the Disclosure Schedule shall have the respective meanings assigned in this Agreement. No reference to or disclosure of any item or other matter in the Disclosure Schedule shall be construed as an admission or indication that such item or other matter is material or that such item or other

matter is required to be referred to or disclosed in the Disclosure Schedule. No disclosure in the Disclosure Schedule relating to any possible breach or violation of any agreement or Law shall be construed as an admission or indication that any such breach or violation exists or has actually occurred. The inclusion of any information in the Disclosure Schedule shall not be deemed to be an admission or acknowledgment by Sellers, in and of itself, that such information is material to or outside the ordinary course of the business of the Partnership Companies or required to be disclosed on the Disclosure Schedule. Each disclosure in the Disclosure Schedule shall constitute disclosure for purposes of the corresponding Sections or subsections of this Agreement expressly referred to in the Disclosure Schedule and any other Section or subsection to the extent such disclosure is made in such a way as to make its relevance to such other Section or subsection readily apparent on its face.

Section 11.8 Acknowledgment by Buyers. Buyers have not relied on any representation or warranty from Sellers or any of their respective Affiliates, except as set forth in this Agreement.

Section 11.9 Amendments and Waivers. This Agreement may be amended, modified, superseded or cancelled, in whole or in part, only by a written instrument duly executed by each of the Parties hereto. Any of the terms of this Agreement and any condition to a Party’s obligations hereunder may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party or Parties waiving such term or condition. No waiver by any Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion. All remedies, either under this Agreement or by law or other afforded, will be cumulative and not alternative.

Section 11.10 Publicity. Except as may otherwise be required by securities Laws and public announcements or disclosures that are, in the reasonable opinion of the Party proposing to make the announcement or disclosure, legally required to be made, prior to the Closing there shall be no press release or public communication concerning the transactions contemplated by this Agreement by any Party except with the prior written consent of the Party not originating such press release or communication, which consent shall not be unreasonably withheld or delayed. Prior to the Closing, Buyers and Sellers will consult in advance on the necessity for, and the timing and content of, any communications to be made to the public and, subject to legal constraints, to the form and content of any application or report to be made to any Governmental Authority that relates to the transactions contemplated by this Agreement.

Section 11.11 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. The Parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise

modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the Parties to the greatest extent legally permissible.

Section 11.12 Governing Law; Jurisdiction.

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

(b) Each Party hereby irrevocably consents to the exclusive personal jurisdiction and venue of the courts of the State of Texas and the federal courts of the United States of America sitting in Xxxxxx County, Texas, and appropriate appellate courts therefrom over any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby, and each Party hereby irrevocably agrees that all claims in respect of such dispute or proceeding may be heard and determined in such courts. The Parties hereby irrevocably waive, to the fullest extent permitted by Law, any objection which they may now or hereafter have to the laying of venue of any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby brought in such court or any defense of lack of personal jurisdiction or inconvenient forum or any similar defense for the maintenance of such dispute. Each Party agrees that a judgment in any such dispute may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law. This consent to jurisdiction is being given solely for purposes of this Agreement and is not intended for and shall not confer consent to jurisdiction with respect to any other dispute in which a Party to this Agreement may become involved.

IN WITNESS WHEREOF this Agreement has been duly executed and delivered by each Party as of the date first above written.
