(ii) (x) customer advances, customer deposits and construction advances, except in the case of this clause (x) to the extent (and only to the extent) such advances and deposits are reflected on the Base Statement (as adjusted pursuant to the Final Closing Statement), and (y) unperformed service obligations, Easement relocation obligations, and engineering and construction required to complete scheduled construction, construction work in progress, and other capital expenditure projects, and to the extent any such individual obligations set forth in this clause (y) exceed $1,000,000.00, as set forth on Schedule 2.2(b)(ii), in each case relating to the Business and outstanding on or arising after the Closing Date;

(iii) the Assumed Environmental Liabilities;

(iv) Taxes for periods on and after the Closing Date to the extent Buyer is obligated to pay such Taxes in accordance with Article XI;

(d) obligations and liabilities of Buyer and its Affiliates under the Employee Agreement.

The liabilities, responsibilities and obligations to be assumed by Buyer pursuant to this Section 2.2 are hereinafter collectively referred to as the “Assumed Liabilities.” Notwithstanding anything in this Section 2.2 to the contrary, the Assumed Liabilities shall not include any liabilities, responsibilities or obligations expressly stated to be Retained Liabilities pursuant to Section 2.3.

Section 2.4 Condition on Assignment or Assumption of Contracts and Rights.

(a) Except as otherwise set forth in this Section 2.4, anything in this Agreement to the contrary notwithstanding, this Agreement shall not constitute an agreement to assign or assume any Material Contract, material Permit or, in each case, any claim or right or any benefit arising thereunder or resulting therefrom if an attempted assignment or assumption thereof, without the Consent of a third party thereto, would constitute a breach thereof. Any transfer or assignment to Buyer by Seller or any of its Affiliates of any property or property rights or any Material Contract or material Permit that requires the Consent of any third party shall be made subject to such Consent being obtained. If such Consent is not obtained, or if an attempted assignment thereof would be ineffective or would affect the rights of Seller or its Affiliate thereunder such that Buyer would not in fact receive all such rights, Seller will continue to use its reasonable best efforts to obtain the relevant Consent until such Consent is obtained or such Material Contract or material Permit expires or is terminated, and will either (at Buyer’s request) (i) cooperate with Buyer in any arrangement that does not constitute a breach of such Material Contract or material Permit, including an operating or other services agreement if reasonably required by Buyer, reasonably designed to provide for Buyer the benefits under any such Material Contract material Permit or rights including enforcement for the benefit of Buyer of any and all rights of Seller or its Affiliates against a third party or Governmental Body thereto arising out of the breach or cancellation by such third party or Governmental Body or otherwise or (ii) subject to the following, assign such Material Contract or material Permit to Buyer.

(b) To the extent that Buyer elects clause (i) of paragraph (a), above, and does receive all of the benefits of any such Contract or rights pursuant to the preceding sentence, Buyer shall accept, and shall indemnify Seller from and against, the burdens (including the

out-of-pocket costs and expenses incurred by Seller in performing such arrangement) and perform the obligations under such Contract as subcontractor of Seller to the extent of the benefit received, and to the extent such burdens and obligations would have constituted an Assumed Liability if such Contract had been transferred to Buyer at the Closing. Seller shall and shall cause its Affiliates to exercise or exploit their respective rights and options under all such Contracts referred to in this Section 2.4 only as reasonably directed by Buyer. Furthermore, if the other party(ies) to such a Contract subsequently Consent to the assignment of such Contract to Buyer, Buyer shall thereupon agree to assume and perform all liabilities and the obligations arising thereunder after the date of such Consent, at which time such Contract shall be deemed an Asset, without the payment of further consideration, and the obligations so assumed thereunder shall be deemed Assumed Liabilities.

(c) To the extent Buyer elects clause (ii) of paragraph (a), above, Buyer shall indemnify Seller from and against any liability associated with such assignment.

Section 2.5 Settlement of Intercompany Accounts. At or prior to the Closing and effective no later than the day immediately prior to the Closing Date, Seller shall cause all intercompany payables, receivables and loans between Missouri Gas Energy relating to the Business, on the one hand, and Seller and its Affiliates (other than Missouri Gas Energy) on the other hand, to be settled or cancelled.

ARTICLE III

PURCHASE PRICE

Section 3.1 Purchase Price. Subject to the terms and conditions of this Agreement, the aggregate purchase price (the “Purchase Price”) for the Assets shall be an amount in cash equal to nine hundred seventy-five million dollars ($975,000,000.00) (the “Estimated Purchase Price”), as adjusted in accordance with Section 3.2(c) (as so adjusted, the “Final Purchase Price”), plus the assumption by Buyer at Closing of the Assumed Liabilities.

Section 3.2 Adjustment to Estimated Purchase Price.

(a) Buyer shall prepare and deliver to Seller within forty-five (45) days following the Closing Date a statement (the “Closing Statement”), which will utilize the same accounting methods, policies, practices, procedures and adjustments as were used in the preparation of the Base Statement, and which shall set forth in reasonable detail the Net Assets of the Business as of the close of business on the date immediately prior to the Closing Date (the “True-Up Amount”).

(b) Following its receipt from Buyer of the Closing Statement, Seller shall have thirty (30) days to review the Closing Statement and the True-Up Amount and to inform Buyer in writing of any disagreement (the “Objection”) that it may have with the Closing Statement or the True-Up Amount, which objection shall specify in reasonable detail Seller’s disagreement with the Closing Statement or the True-Up Amount. Buyer agrees, at no cost to Seller, to give Seller and its authorized Representatives reasonable access to such employees, officers and other facilities and such books and records of Buyer and its Affiliates as are

reasonably necessary to allow Seller and its authorized Representatives to review the Closing Statement and the True-Up Amount. If Buyer does not receive the Objection within such thirty (30) day period, the True-Up Amount and the other amounts set forth on the Closing Statement delivered pursuant to Section 3.2(a) shall be deemed to have been accepted by Seller and shall become binding upon Seller. If Seller does timely deliver an Objection to Buyer, Buyer shall then have fifteen (15) days from the date of receipt of such Objection (the “Review Period”) to review and respond to the Objection. Seller and Buyer shall attempt in good faith to resolve any disagreements with respect to the Closing Statement or the True-Up Amount. If they are unable to resolve all of their disagreements with respect to the Closing Statement or the True-Up Amount within twenty (20) days following the expiration of Buyer’s Review Period, they may refer, at the option of either Buyer or Seller, their differences to an internationally recognized firm of independent public accountants selected jointly by Buyer and Seller, which accountants shall determine, only with respect to the disagreements so submitted, whether and to what extent, if any, the amounts set forth on the Closing Statement or the True-Up Amount require adjustment. If Buyer and Seller are unable to so select the independent public accountants within twenty (20) days, either Buyer or Seller may thereafter request that the American Arbitration Association make such selection (as applicable, the firm selected by Buyer and Seller or the firm selected by the American Arbitration Association is herein referred to as the “CPA Firm”). Buyer and Seller shall direct the CPA Firm to use its reasonable best efforts to render its determination within thirty (30) days after the issue is first submitted to the CPA Firm. The CPA Firm’s determination shall be conclusive and binding upon Buyer and Seller. The fees and disbursements of the CPA Firm shall be borne by Buyer and Seller in inverse proportion as they may prevail on matters resolved by the CPA Firm, which proportionate allocations shall also be determined by the CPA Firm at the time the determination of the CPA Firm is rendered on the Closing Statement or the True-Up Amount. Buyer and Seller shall make readily available to the CPA Firm all relevant books and records relating to the Closing Statement and all other items reasonably requested by the CPA Firm. The Closing Statement and True-Up Amount as agreed to by Buyer and Seller or as determined by the CPA Firm shall be referred to as the “Final Closing Statement.”

(c) In the event of a positive difference between the True-Up Amount on the Final Closing Statement and the Net Assets as set forth on the Base Statement, Buyer shall pay to Seller in cash the amount of such difference, plus the Settlement Interest thereon. In the event of a negative difference between the True-Up Amount on the Final Closing Statement and the Net Assets as set forth on the Base Statement, Seller shall pay to Buyer in cash the amount of such difference, plus the Settlement Interest thereon. All amounts payable under this Section 3.2(c) shall be paid within five (5) Business Days of the determination of the Final Closing Statement by wire transfer of immediately available funds to a bank account designated in writing by the recipient not less than one (1) Business Day before such payment.

Seller’s Pension Plans and Seller’s 401(k) Plan are the only Employee Plans that are intended to be qualified under Section 401(a) of the IRC. Other than Employees and Former Employees of the Business (and their applicable beneficiaries), no individuals participate in or are otherwise entitled to receive benefits from Seller’s Pension Plans. Each Employee Plan that is subject to Section 302 or Title IV of ERISA or Sections 412 and 430 of the IRC is hereinafter referred to as a “Title IV Plan.” Other than as specifically set forth in the Employee Agreement, Buyer shall have no liability with respect to any Employee Plan of Seller or any of its Affiliates.

(b) With respect to each Employee Plan, Seller has heretofore delivered to Buyer true and complete copies of the Employee Plan and any amendments thereto (or if the Employee Plan is not a written Employee Plan, a description thereof), any related trust or other funding vehicle documents, the most recent actuarial valuation reports, annual reports, Forms 5500 and asset statements, in each case, as applicable, any summary plan descriptions required under ERISA or the IRC and the most recent determination letter received from the IRS with respect to each Employee Plan intended to qualify under Section 401 of the IRC.

Except as set forth on Schedule 5.12(c), since May 1, 2010 to the date of this Agreement, there has been no “reportable

event” (as such term is defined in Section 4043 of ERISA) in connection with any of Seller’s Pension Plans other than reportable events for which notice is waived under applicable regulations.

(d) Except as set forth on Schedule 5.12(d), all contributions, premiums or payments required to be made by Seller or any of its ERISA Affiliates with respect to any Employee Plan prior to the Closing Date have been timely made prior to the Closing Date or, if not yet due, have been reflected in the Financial Statements in accordance with GAAP, and will be reflected in the Carve-Out Financials in accordance with GAAP when delivered.

(e) No Title IV Plan that is maintained or contributed to by Seller or its ERISA Affiliates and for which Buyer could, directly or indirectly, reasonably be expected to have liability, is or has been a multiemployer plan, as defined in Section 3(37) of ERISA, nor is any Title IV Plan a plan described in Section 4063(a) of ERISA. Neither Seller nor any ERISA Affiliate has made or suffered a complete withdrawal or a partial withdrawal, as determined under Sections 4203 and 4205 of ERISA (or any liability resulting therefrom has been satisfied in full). With respect to each Title IV Plan, as of the date of this Agreement, there has been no material change in the financial condition of any such Title IV Plan since the last day of its most recently completed fiscal year.

(f) None of Seller, any Employee Plan, any trust created thereunder, or any trustee or administrator thereof has engaged in a transaction in connection with which Seller or any Employee Plan could be subject to either a material penalty assessed pursuant to Section 409 or 502(i) of ERISA or a material tax imposed pursuant to Section 4975 or 4976 of the IRC.

(g) Each Employee Plan has been operated and administered (including with respect to required contributions thereunder) in all material respects in accordance with its terms and applicable law, including but not limited to ERISA and the IRC.

(h) Each Employee Plan intended to be qualified under Section 401(a) of the IRC is so qualified and has received a favorable determination or opinion letter as to its qualification. To the Knowledge of Seller, nothing has occurred since the date of determination of such qualification and exemption that would reasonably be expected to materially adversely affect the qualified or exempt status of such Employee Plan or trust. Each Employee Plan intended to satisfy the requirements of Section 501(c)(9) of the IRC has satisfied such requirements in all material respects.

(i) Except as disclosed in Schedule 5.12(i)(A), no Employee Plan provides medical, surgical, hospitalization, death or similar benefits coverage (whether or not insured) for Employees or Former Employees for periods extending beyond their retirement or other termination of service, other than (A) coverage mandated by Section 4980B of the IRC, Section 601 et seq of ERISA, or comparable provisions of state law, (B) death benefits under any pension plan, or (C) benefits the full cost of which is borne by the Employee or Former Employee (or in either case, his beneficiary).

(k) Except as disclosed in Schedule 5.12(k), the consummation of the transactions contemplated by this Agreement will not, either alone or in combination with another event, (i) entitle any Employee or Former Employee to severance pay or any other payment, or (ii) accelerate the time of payment or vesting, or increase the amount of compensation due an Employee or Former Employee.

(l) Except as would not result in material cost or liability to Buyer or its Affiliates, there are no pending or, to the Knowledge of Seller, Threatened or anticipated claims, liens, lawsuits or complaints by or on behalf of any Employee Plan, by any Employee, Former Employee or beneficiary thereof covered under any such Employee Plan, or otherwise involving any such Employee Plan (other than routine claims for benefits).

(m) Except as disclosed in Schedule 5.12(m), (i) Seller has no plan, contract or commitment, whether legally binding or not, to create any additional employee benefit or compensation plans, policies or arrangements or, except as may be required by applicable law, to modify any Employee Plan, and (ii) each Employee Plan that provides medical, surgical, hospitalization, death or similar benefits coverage (whether or not insured) for Employees or Former Employees for periods extending beyond their retirement or other termination of service may be amended, modified or terminated at any time without incurring liability thereunder, other than medical or welfare claims incurred prior to such amendment or termination.

(n) The only representations and warranties given in respect of employee benefit matters are those contained in this Section 5.12, the Employee Agreement and, to the extent related to the funding (or underfunding) of any Employee Plan, Section 5.5, and none of the other representations and warranties set forth in this Agreement shall be deemed to constitute, directly or indirectly, a representation or warranty in respect of employee benefit matters.

Except as expressly provided in Section 6.1(b), neither such notice nor the receiving party’s resulting knowledge of the matters disclosed therein shall be deemed to waive or limit in any respect any representation or warranty, rights in respect thereof, or conditions to the consummation of the transactions under this Agreement

(d) Confidentiality. From and after the Closing Date, Seller shall, and shall cause its Affiliates and their respective Representatives to, keep confidential and not disclose any information relating to the Business (whether in the possession of Seller, any Affiliate of Seller or such Representatives at the time of the Closing or subsequently obtained by Seller, any Affiliate of Seller or any such Representative from Buyer pursuant to this Agreement or any Related Document) (“Restricted Information”), and shall not directly or indirectly use such Restricted Information for any purpose, except as and to the extent permitted by the terms of this Agreement or any Related Document. The obligation to keep such Restricted Information confidential shall continue indefinitely from the Closing Date and shall not apply to any information which (i) is in the public domain, (ii) is published or otherwise becomes part of the public domain through no fault of Seller, any of its Affiliates or any of their Representatives or (iii) becomes available to Seller, any of its Affiliates or any of their Representatives on a non-confidential basis from a source that did not acquire such information (directly or indirectly) from Seller or Buyer on a confidential basis. Notwithstanding the foregoing, Seller may make disclosures required by law; provided, that Seller, to the extent practicable, shall provide Buyer with prompt notice thereof so that Buyer may seek a protective order or other appropriate remedy or waive compliance with the provisions of this Section 6.1(d). In the event that such protective order or other remedy is not obtained or Buyer waives compliance with the provisions of this Section 6.1(d), Seller shall, or shall cause the Person required to disclose such Restricted Information to, furnish only that portion of the information that such Person is advised by an opinion of Seller’s counsel is legally required, and, to the extent practicable, Seller shall exercise its reasonable best efforts to obtain reliable assurance that confidential treatment is accorded the Restricted Information so furnished.

(e) Non-Solicitation of Employees. Except as otherwise set forth in Section 2.3 of the Employee Agreement, for a period of two (2) years after the Closing Date, Seller shall not, and shall cause its Affiliates not to, without the prior written approval of Buyer, directly or indirectly, solicit, encourage, entice or induce any Transferred Employee or any other employee of Buyer or its Affiliates to terminate his or her employment with Buyer or any of its Affiliates; provided, however, that such prohibition shall not apply to any person who responds to a general solicitation.

(f) Assets Owned by Affiliates. Prior to or at the Closing, Seller shall cause each of its Affiliates that holds any interest in any of the Assets as of the Closing Date to cause such Assets to be transferred and conveyed to Buyer hereunder upon the Closing (and any liability of Seller to any of its Affiliates created thereby shall be deemed an Excluded Liability).

Section 6.2 Covenants of Buyer. Buyer agrees to observe and perform the following covenants and agreements:

(a) Access to Information. After Closing, Buyer will, and will cause its Representatives to, at no cost to Buyer or its Representatives, afford to Seller, including its Representatives, on reasonable notice and at reasonable times, reasonable access to all books, records, files and documents related to the Business in order to permit Seller to prepare and file its Tax Returns and to prepare for and participate in any investigation with respect thereto, to prepare for and participate in any other investigation and defend any Proceedings relating to or involving Seller or the Business for which Seller may be responsible, to discharge its obligations under this Agreement and the other Related Documents to which it is a party and for other reasonable purposes and will afford Seller reasonable assistance in connection therewith. Buyer will cause such records to be maintained for not less than seven (7) years from the Closing Date and will not dispose of such records without first offering in writing to deliver them to Seller; provided, however, that in the event that Buyer transfers all or a portion of the Business to any third party during such period, Buyer may transfer to such third party all or a portion of the books, records, files and documents related thereof, provided such third party transferee expressly assumes in writing the obligations of Buyer under this Section 6.2(a). In addition, on and after the Closing Date, at Seller’s request, Buyer shall make available to Seller and its Affiliates and Representatives, on reasonable notice and at reasonable times, those employees of Buyer reasonably requested by Seller in connection with any Proceeding, including to provide testimony, to be deposed, to act as witnesses and to assist counsel; provided, however, that (i) such access to such employees shall not unreasonably interfere with the normal conduct of the operations of Buyer and (ii) Seller shall reimburse Buyer for the out-of-pocket costs reasonably incurred by Buyer in making such employees available to Seller. Without limiting the application of Section 6.1(d), all documents or information furnished by Buyer or obtained by Seller or its Representatives hereunder shall be subject to Section 6.1(d).

(b) Seller Guarantees and Surety Instruments. Buyer shall use its commercially reasonable efforts to assist Seller in obtaining full and complete releases on the guarantees, letters of credit, bonds and other surety instruments provided by Seller in connection with the Business, all of which have been listed by Seller on Schedule 6.2(b). For purposes of this Section 6.2(b), commercially reasonable efforts shall include: (i) Buyer’s assumption of the Contracts on the terms set forth in this Agreement; and (ii) an obligation on the part of Buyer to provide a guaranty, letter of credit, bond or other surety instrument at Closing (upon substantially the same terms as such surety instrument provided by Seller) to the extent required by any Contract assumed by Buyer at Closing and, in general, no later than ninety (90) days after the Closing Date but effective as of the Closing Date, an equivalent surety instrument (upon substantially the same terms as such surety instrument provided by Seller) to be substituted for any surety instrument provided by Seller to any beneficiary in connection with the Business. Buyer shall indemnify, defend and hold harmless Seller and its Affiliates for any and all Losses (in each case without deduction or set off) incurred on account of Seller’s guarantees, letters of credit, bonds and other surety instruments on or after the Closing Date insofar as such Losses relate to any failure of Buyer to perform or discharge any Assumed Liability on or after the Closing.

Section 6.3 Reasonable Best Efforts; Governmental Filings.

(a) Reasonable Best Efforts. Subject to the terms and conditions set forth in this Agreement, each party hereto shall use its reasonable best efforts (subject to, and in accordance with, applicable Law) to take, or cause to be taken, promptly all actions, and to do, or cause to be done, promptly and to assist and cooperate with the other parties in doing, all things necessary, proper or advisable under applicable Laws to consummate the transactions contemplated by this Agreement and the Related Documents, including: (i) the obtaining of all necessary Consents required to consummate the transactions contemplated by this Agreement and the Related Documents in a timely manner, including any Consent required under any Legal Requirement, Contract, Lease or Easement applicable to the Business and all Consents listed in Schedule 5.3, (ii) the defending of any lawsuits or other legal proceedings, whether judicial or administrative, challenging this Agreement or the Related Documents or the consummation of the transactions contemplated hereby or thereby, including seeking to have any stay or temporary restraining order entered by any Governmental Body vacated or reversed, and (iii) the execution and delivery of any additional instruments necessary to consummate the transactions contemplated by this Agreement and the Related Documents; provided, however, that in no event shall Seller or its Affiliates be required to pay any penalty, compensation or other consideration to any third party for any such Consent. In the event that any Proceeding is commenced challenging the proposed transactions contemplated by this Agreement or the Related Documents, each of the parties shall cooperate with each other and use its respective reasonable best efforts to contest and resist any such Proceeding and to have vacated, lifted, reversed or overturned any Order, whether temporary, preliminary or permanent, that is in effect and that prohibits, prevents or restricts consummation of the transactions contemplated by this Agreement or the Related Documents.

(b) HSR Act Filing. Buyer and Seller shall use their respective reasonable best efforts to make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby no later than thirty (30) days following the date of this Agreement. Buyer and Seller shall supply as promptly as practicable any additional information or documentary material that may be requested pursuant to the HSR Act and shall take all other actions necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act as soon as practicable (such expiration or termination is hereinafter referred to as “Clearance”). Subject to the last sentence of this Section 6.3(b), Buyer and Seller shall use their reasonable best efforts to keep the other party informed with respect to the status of submissions under the HSR Act, including with respect to: (i) the receipt of any non-action, action, clearance, consent, approval or waiver, (ii) the expiration of any waiting period, (iii) the commencement or proposed or threatened commencement of any investigation, litigation or administrative or judicial action or proceeding and (iv) the nature and status of any objections raised or proposed or threatened to be raised with respect to this Agreement or the transactions contemplated hereby. Buyer and Seller shall comply substantially with any lawful additional requests for information, including requests for production of documents and production of witnesses for interviews or depositions, made by the Antitrust Division of the United States Department of Justice or the United States Federal Trade Commission (the “Antitrust Authorities”) and use their respective reasonable best efforts to take all other actions to obtain Clearance from the Antitrust Authorities, including, without limitation, agreeing to divest, hold separate or otherwise restrict the use or operation of any business or assets of Buyer or Seller or any of their respective subsidiaries and agreeing to any conduct or other remedy in order to secure Clearance from Antitrust Authorities (each, a “Divestiture Action”). Buyer and its Affiliates shall use their respective reasonable best efforts to take promptly any steps necessary to obtain Clearance from the Antitrust Authorities as promptly as practicable in order to allow the consummation of the transactions contemplated by this Agreement and the Related Documents no later than the End Date, provided, that, for the avoidance of doubt and notwithstanding anything to the contrary contained in this Agreement, neither party shall be required or obligated (and shall not be obligated to cause any of its subsidiaries) to take any Divestiture Action if doing so would, individually or in the aggregate, have a Material Adverse Effect.

(c) Other Regulatory Filings. Buyer and Seller will prepare and file (i) no later than thirty (30) days following the date of this Agreement, a joint application, substantially in the form of Schedule 6.3(c)(i), to the MPSC for the approval by the MPSC of the transactions contemplated hereby, accompanied by any required direct testimony in support of such application, and (ii) promptly following the date of this Agreement, with any other Governmental Body, requests for such other Consents as may be necessary for the consummation of the transactions contemplated by this Agreement or the Related Documents. Buyer and Seller will diligently pursue such Consents and will cooperate with each other in seeking such Consents. To such end, the parties agree to make available the personnel and other resources of their respective organizations in order to obtain all such Consents. Each party will promptly inform the other party of any communication received by such party from, or given by such party to, any Governmental Body from which any such Consent is required and of any material communication received or given in connection with any Proceeding by a private party,

in each case regarding any of the transactions contemplated hereby, and will permit the other party to review any communication given by it to, and consult with each other in advance of any meeting or conference with, any such Governmental Body or, in connection with any Proceeding by a private party, with such other Person, and to the extent permitted by such Governmental Body or other Person, give the other party the opportunity to attend and to participate in such meetings and conferences. Buyer shall use its reasonable best efforts to (i) take promptly any and all steps necessary to resolve the issues raised by the MPSC, its Staff or parties to the proceedings before the MPSC in connection with the transactions contemplated by this Agreement and (ii) obtain approval from the MPSC as promptly as practicable in order to allow the consummation of the transactions contemplated by this Agreement no later than the End Date, including committing to and effecting, by stipulation, settlement or otherwise, conditions on Buyer or the Assets imposed by the MPSC, including the conditions approved by the MPSC in the Non-Unanimous Stipulation and Agreement in Case No. GM-2011-0412; provided, however, that Buyer shall not be required or obligated (and shall not be obligated to cause any of its subsidiaries) to take any action if such action would have a Material Adverse Effect.

Section 6.4 Seller Marks. No later than one hundred eighty (180) days after the Closing Date, Buyer shall cease using any names, marks, trade names, trademarks and corporate symbols and logos incorporating “Southern Union”, “Southern,” “SU” and “SUG” (collectively and together with all other names, marks, trade names, trademarks and corporate symbols and logos owned by Seller or any of its Affiliates, other than those included in the Assets, the “Seller Marks”) and shall remove from the Assets any and all Seller Marks. Thereafter, except as required by Legal Requirement or with the prior written consent of Seller, Buyer shall not use any Seller Mark or any name or term confusingly similar to any Seller Mark in connection with the sale of any products or services, in the corporate or doing business name of any of its Affiliates or otherwise in the conduct of its or any of its Affiliates’ businesses or operations. In the event that Buyer breaches this Section 6.4, Seller shall be entitled to specific performance of this Section 6.4 and to injunctive relief against further violations, as well as any other remedies at law or in equity available to Seller.

Section 6.5 Acknowledgment by Buyer. In order to induce Seller to enter into and perform this Agreement and the Related Documents, Buyer acknowledges and agrees with Seller as follows:

THE REPRESENTATIONS AND WARRANTIES SET FORTH IN THIS AGREEMENT AND THE RELATED DOCUMENTS CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF SELLER TO BUYER IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY, AND THERE ARE NO REPRESENTATIONS, WARRANTIES, COVENANTS, UNDERSTANDINGS OR AGREEMENTS, ORAL OR WRITTEN, IN RELATION THERETO BETWEEN THE PARTIES OTHER THAN THOSE INCORPORATED HEREIN AND THEREIN. EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES EXPRESSLY SET FORTH IN THIS AGREEMENT AND THE RELATED DOCUMENTS, BUYER

DISCLAIMS RELIANCE ON ANY REPRESENTATIONS OR WARRANTIES, EITHER EXPRESS OR IMPLIED, BY OR ON BEHALF OF SELLER OR ITS AFFILIATES OR REPRESENTATIVES. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, BUYER ACKNOWLEDGES AND AGREES THAT, EXCEPT AS PROVIDED IN SECTION 5.14, THERE ARE NO REPRESENTATIONS OR WARRANTIES OF SELLER WITH RESPECT COMPLIANCE WITH ENVIRONMENTAL LAWS AND ENVIRONMENTAL PERMITS OR THE PRESENCE OR RELEASES OF HAZARDOUS MATERIAL IN THE FIXTURES, SOILS, GROUNDWATER, SURFACE WATER OR AIR ON, UNDER OR ABOUT OR EMANATING FROM ANY OF THE PROPERTIES OR ASSETS OF SELLER.

Section 6.6 Continuing Services. Within fifteen (15) days after the execution date of this Agreement, Buyer shall deliver to Seller a list of its proposed Representatives to a joint continuing services team, which shall include individuals with expertise from various functional specialties associated or involved in providing billing, payroll and other support services provided to the Business by any automated or manual process using facilities or employees that are not included among the Assets or Transferred Employees. Seller will add its Representatives to such team within fifteen (15) days after receipt of Buyer’s list. Such team will be responsible for preparing as soon as reasonably practicable after the execution date of this Agreement, and timely implementing, a continuing services plan that will identify and describe substantially all of the various continuing services activities that the parties will cause to occur before and after the Closing and any other transfer of control matters that any party reasonably believes should be addressed in such continuing services plan, substantially in the form attached hereto as Exhibit 6.6 (the “Continuing Services Agreement”). Buyer and Seller shall use their commercially reasonable efforts to cause their Representatives on such continuing services team to cooperate in good faith and take all reasonable steps necessary to develop a mutually acceptable continuing services plan. The specific continuing services activities will be mutually agreed upon and more fully set forth in a definitive Continuing Services Agreement to be executed and delivered by Buyer and Seller at the Closing.

Section 6.7 Risk of Loss. The risk of any loss, damage, impairment, confiscation or condemnation of any of the Assets from any cause whatsoever shall be borne by Seller at all times prior to the Closing, and by Buyer at all times thereafter (subject to the representations and warranties of Seller set forth in this Agreement and the Related Documents and Buyer’s rights to indemnification pursuant to Section 12.1). If any such loss, damage, impairment, confiscation or condemnation occurs prior to Closing, Seller shall apply the proceeds of any insurance policy, judgment or award with respect thereto to repair, replace or restore the Assets as soon as reasonably practicable (whether before or after Closing) to their prior condition; provided, however, anything contained in this Agreement to the contrary notwithstanding, Seller shall not be obligated to expend sums in excess of the proceeds of any insurance policy (together with the amount of any deductible or self-insured retention), judgment or award with respect to any loss, damage, impairment, confiscation or condemnation of any of the Assets in order to repair, replace or restore such Assets to their prior condition. In the event (“Casualty Event”) of any

damage or destruction to the Assets which would result in the nonsatisfaction of a condition precedent to Buyer’s obligation to consummate this Agreement, Buyer at its option, may proceed to close this Agreement on the Closing Date, in which event Seller shall pay or assign to Buyer (together with the amount of any deductible or self-insured retention) the proceeds from any insurance policies covering Assets subject to the Casualty Event to the extent such proceeds are received by or payable to Seller and have not been used in or committed to the restoration or replacement of Assets subject to the Casualty Event as of the Closing Date. For the avoidance of doubt, the determination of whether there has been any damage or destruction to the Assets which would result in the nonsatisfaction of a condition precedent to Buyer’s obligation to consummate this Agreement shall only take into account those repairs, replacements and restorations that have actually taken place.

Section 6.8 Outstanding Payments and Bank Accounts.

(a) Notwithstanding anything contained herein to the contrary, (i) to the extent elected by Buyer prior to the Closing, all of the bank accounts and lock boxes of Seller used in or in connection with the Business shall be considered “Assets” for purposes of this Agreement and shall be transferred to Buyer at the Closing, (ii) any checks that are in the possession of Seller at the Closing that relate to accounts receivable (or any other asset) included in the Assets shall be transferred to Buyer at the Closing and (iii) any checks that are in the possession of Seller at the Closing that relate to accounts receivable (or any other asset) not included in the Assets shall be retained by Seller.

(b) From and after the Closing, (i) if Seller or any of its Affiliates receives or collects any funds relating to any accounts receivable (or any other asset) included in the Assets, Seller or its Affiliates shall remit any such amounts to Buyer as promptly as practicable but no later than ten (10) days after Seller or any of its Affiliates receives such sum, and (ii) Seller and its Affiliates shall promptly forward all mail, remittances, receipts or other mailings received by any of them relating to the Business to Buyer.

Section 6.9 Financing.

(a) Subject to the terms and conditions of this Agreement, Buyer shall use its reasonable best efforts to obtain the Financing on the terms and conditions described in the Financing Letter, after giving effect to the market flex terms in the Fee Letter, and shall not permit any amendment or modification to be made to (other than to amend the Financing Letter to add lenders, lead arrangers, book runners, syndication agents or similar entities who had not executed the Financing Letter as of the date of this Agreement), or any waiver of any provision or remedy under, the Financing Letter or the Fee Letter, if such amendment, modification or waiver (i) reduces the aggregate amount of the Financing or (ii) imposes new or additional conditions or other terms or otherwise expands, amends or modifies any of the conditions to the receipt of the Financing or other terms in a manner that would reasonably be expected to (x) delay or prevent the Closing (y) make the timely funding of the Financing or satisfaction of the conditions to obtaining the Financing less likely to occur or (z) adversely impact the ability of Buyer to enforce its rights against the other parties to the Financing Letter or the definitive

agreements with respect thereto; provided that Buyer shall have the right to substitute other financing for all or any portion of the Financing from the same and/or alternative financing sources; provided, further, that such substitution shall only be permitted if (i) the terms thereof would not be reasonably expected to delay or prevent the Closing or make the timely funding of the Financing or satisfaction of the conditions to obtaining the Financing less likely to occur and (ii) the conditions to the Financing set forth in the Financing Letter would not be expanded or modified in a manner that would reasonably be expected to delay or prevent the Closing, provided, still further, that any such substitute financing shall not obligate any of Seller or its Affiliates as a surety, guarantor or indemnitor or to extend credit to any Person. Any reference in this Agreement to (A) “Financing,” shall include the financing contemplated by the Financing Letter as amended or modified in compliance with this Section 6.9(a) and (B) “Financing Letter,” and “Fee Letter” shall include such documents as amended or modified in compliance with this Section 6.9(a).

(b) Buyer shall use its reasonable best efforts (i) to maintain in effect the Financing Letter in accordance with the terms and subject to the conditions thereof, (ii) to negotiate and enter into all definitive agreements with respect to the Financing on the terms and conditions contained in the Financing Letter, including the market flex provisions in the Fee Letter, and (iii) to satisfy all conditions to such definitive agreements and consummate the Financing at or prior to the Closing. Buyer shall keep Seller reasonably apprised of the status of the Financing and developments with respect thereto (including giving Seller prompt notice of any material change with respect to such Financing) and shall provide to Seller copies of all material definitive documents related to the Financing. Without limiting the generality of the foregoing, Buyer agrees to notify Seller promptly, and in any event within two (2) Business Days, if at any time (x) the Financing Letter shall expire or be terminated for any reason, (y) any of the other parties to the Financing Letter notify Buyer that such party no longer intends to provide financing on the terms set forth therein or (z) to Buyer’s knowledge (without a requirement of due inquiry), any of the other parties to the Financing Letter is or is alleged to be in breach or default thereunder.

(c) To the extent necessary to complete the transactions contemplated hereby, Buyer shall use its reasonable best efforts to cause the parties providing Financing to fund on the Closing Date the Financing required to consummate the transactions contemplated hereby and the other transactions contemplated by the Financing Letter, including by taking enforcement action, if all conditions in the Financing Letter and all conditions to Closing contained in this Agreement are satisfied or waived, or upon funding will be satisfied.

(d) If the Financing Letter shall be terminated or modified in a manner materially adverse to Buyer, if the Financing Letter shall be materially breached or repudiated by the other parties to the Financing Letter, or if any portion of the Financing becomes unavailable on the terms and conditions contemplated in the Financing Letter (other than as a result of obtaining substitute debt financing in accordance with Section 6.9(a)) (such event, an “Original Financing Failure”), Buyer shall use its reasonable best efforts to arrange promptly to obtain alternative financing from alternative sources on terms and conditions not less favorable to Buyer than those contained in the Financing Letter and the Fee Letter and in an amount at least

equal to the Financing or such unavailable portion thereof, as the case may be (the “Alternate Financing”), and to obtain a new financing commitment letter with respect to such Alternate Financing (the “New Financing Letter”), which shall replace the existing Financing Letter, provided that any such Alternate Financing shall not obligate any of Seller or its Affiliates as a surety, guarantor or indemnitor or to extend credit to any Person (the terms described in this proviso “Prohibited Alternate Terms”). Buyer shall not execute a New Financing Letter or consummate any Alternate Financing, without the written consent of Seller, if (i) the terms of the New Financing Letter or Alternate Financing are, in the aggregate, less favorable to the Seller than the Financing Letter or the Financing (without giving effect to the Original Financing Failure), (ii) the terms thereof would be reasonably expected to delay or prevent the Closing or make the timely funding of the Alternate Financing or satisfaction of the conditions to obtaining the Alternate Financing less likely to occur, as compared to the Financing Letter and the Financing (without giving effect to the Original Financing Failure) or (iii) the conditions to the Alternate Financing set forth in the New Financing Letter would be expanded or modified in a manner that would reasonably be expected to delay or prevent the Closing, as compared to the Financing Letter and the Financing (without giving effect to the Original Financing Failure). Buyer shall promptly provide a true, correct and complete copy of such New Financing Letter to Seller. In the event any New Financing Letter is obtained, (i) any reference in this Agreement to the “Financing” shall mean the financing contemplated by the Financing Letter as modified pursuant to clause (ii) below, (ii) any reference in this Agreement to the “Financing Letter” shall be deemed to include the Financing Letter that is not superseded by a New Financing Letter at the time in question and the New Financing Letter to the extent then in effect and (iii) any reference in this Agreement to “Fee Letter” shall be deemed to include any fee or other letter relating to the Financing Letter that are not superseded by a New Financing Letter at the time in question and the New Financing Letter to the extent then in effect.

(e) Notwithstanding anything to the contrary set forth in this Agreement, with the consent of Seller, Buyer shall be entitled to pursue substitute financing, the terms of which may differ from the terms set forth in the Financing Letter and such substitute financing may not constitute Alternate Financing. No actions taken by Buyer, its Affiliates or their respective Representatives in connection therewith shall in and of itself constitute a breach of the obligations of Buyer under this Agreement.

(f) Notwithstanding anything to the contrary set forth in paragraphs (a)-(e) of this Section 6.9, Buyer hereby acknowledges and agrees that receipt of the Financing or Alternate Financing does not constitute a condition to the consummation of the transactions contemplated by this Agreement.

Section 6.10 Financing Cooperation.

(a) For purposes of this Section 6.10, the term “Financing” shall include any Permanent Financing (as defined in the Financing Letter), whether for debt, equity or otherwise. Prior to the Closing, Seller shall, and shall use reasonable best efforts to cause each of its Affiliates and Representatives to, use reasonable best efforts to provide to Buyer such cooperation reasonably requested by Buyer and reasonably required in connection with the Financing or the Alternate Financing, including (to the extent reasonably requested and reasonably required):

(i) participating in a customary and reasonable number of meetings, presentations, due diligence sessions, drafting sessions, road shows and sessions with rating agencies;

(ii) assisting with the preparation of materials for rating agency presentations, offering documents, private placement memoranda, bank information memoranda, prospectuses (registered or otherwise) and similar documents for the Financing, including execution and delivery of customary representation letters in connection with an audit of the Business and auditors comfort letter;

(iv) in addition to the information required pursuant to clause (iii), above, as promptly as reasonably practical, furnishing Buyer and the other parties to the Financing Letter with financial and other information regarding the Business and the Assets as may be reasonably requested by Buyer (including in connection with Buyer’s preparation of pro forma financial statements), including unaudited interim financial statements, financial data, projections, audit reports and other information of the type required by Regulation S-X and Regulation S-K of the Securities Act of 1933 for a registered public offering, and of type and form customarily included in private placements under Rule 144A, to consummate the offering(s) of debt or equity securities contemplated by the Financing, or as otherwise reasonably required in connection with the Financing, or as otherwise necessary in order to assist in receiving customary “comfort” (including “negative assurance” comfort) from independent accountants in connection with the offering(s) of debt or equity securities contemplated by the Financing (all such information in clause (iii) and this clause (iv), including the Carve-Out Financials, the “Required Information”);

(v) providing information relating to the Business that is reasonably available to it to assist in the preparation of any credit agreements, indentures, purchase agreements, currency or interest hedging arrangements, other definitive financing documents, officer’s certificates, customary closing documents, or other certificates or documents with respect to the Financing contemplated by the Financing as may be reasonably requested by Buyer;

(vi) furnishing Buyer and their Financing sources as promptly as practicable all financial information required to be delivered pursuant to the Financing Letter and monthly financial statements for the Business (to the extent prepared in the ordinary course of business);

(vii) assisting Buyer to obtain waivers, consents, estoppels and approvals from other parties to Contracts, material Leases and Easements, and Encumbrances to which the Assets or the Business are bound; and

(viii) cooperating with Buyer in its efforts to obtain accountants’ comfort Letter, consents, legal opinions, surveys, appraisals, engineering reports, environmental and other inspections, title insurance and other documentation and items relating to the Financing, as reasonably requested by Buyer;

provided that (A) nothing herein shall require such cooperation to the extent it would require Seller or any of its Affiliates to waive or amend any terms of this Agreement, incur any Liabilities, pay any fees, reimburse any expenses, in each case, with respect to the Financing, prior to the Closing for which it has not received prior reimbursement by or on behalf of Buyer, or would cause Seller or any of its Affiliates to breach this Agreement or become unable to satisfy a condition to the Closing, (B) nothing herein shall require such cooperation from Seller or its Affiliates to the extent it would unreasonably interfere with the ongoing operations of Seller or its Affiliates and (C) there shall be no action, Liability or obligation of Seller or its Affiliates under any certificate, agreement, arrangement, document or instrument relating to the Financing. Notwithstanding anything to the contrary in this Section 6.10, neither Seller nor its Affiliates shall be in breach of the covenant set forth in this Section 6.10 if it has acted in good faith to comply with the cooperation and assistance set forth herein.

(b) Buyer shall indemnify the Seller Indemnitees from, against and in respect of any Losses imposed on, sustained, incurred or suffered by, or asserted against, any of them, directly or indirectly relating to, arising out of or resulting from the arrangement of the Financing, any other financing and/or the provision of information utilized in connection therewith to the fullest extent permitted by applicable Legal Requirement.

(c) Seller will use its reasonable best efforts to update Required Information provided to Buyer pursuant to clauses (iii) and (iv) of Section 6.10(a) as may be necessary such that the Required Information does not contain any untrue statement of material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which they were made, not misleading.

ARTICLE IX

TERMINATION

Section 9.1 Termination Rights. This Agreement may be terminated in its entirety at any time prior to the Closing:

(a) By the mutual written agreement of Seller and Buyer;

(b) By Buyer, on the one hand, or Seller, on the other hand, in writing if there shall be in effect a Final Order prohibiting, enjoining or restricting the transactions contemplated by this Agreement;

(c) By either party in writing if there shall have been a material breach of any of the representations or warranties set forth in this Agreement and the Related Documents (which, for purposes of this Article IX, shall include any violation of or inaccuracy in any of the representations or warranties set forth in this Agreement or the Related Documents as measured on any relevant date (not just the date hereof and the Closing Date)) on the part of the other party, which breach is not cured within thirty (30) days following receipt by the breaching party of written notice of such breach from the terminating party, or which breach, by its nature, cannot be cured prior to the Closing; provided, however, that neither party shall have the right to terminate this Agreement pursuant to this Section 9.1(c) unless the breach of a representation or warranty, together with all other such breaches, would entitle the party receiving such representation not to consummate the transactions contemplated by this Agreement under Section 7.2(a) (in the case of a breach of a representation or warranty by Seller) or Section 7.1(a) (in the case of a breach of a representation or warranty by Buyer) and provided, further, that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein;

(d) By either party in writing if there shall have been a material breach of any of the covenants or agreements set forth in this Agreement or in the Related Documents on the part of the other party, which breach shall not have been cured within thirty (30) days following receipt by the breaching party of written notice of such breach from the terminating party, or which breach, by its nature, cannot be cured prior to the Closing (provided that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein or in the Related Documents);

(e) By either party in writing if the Closing has not occurred by the date that is ten (10) months after the date of this Agreement (the “End Date”); provided, however, that the right to terminate this Agreement under this Section 9.1(e) will not be available to any party that is in material breach of its representations, warranties, covenants or agreements contained herein or in the Related Documents; and provided further that in the event Seller’s conditions precedent to Closing set forth in Section 7.1(d) or 7.1(e) or Buyer’s conditions precedent to Closing set forth in Sections 7.2(d) or 7.2(e) have not been satisfied prior to the End Date but are reasonably capable of being satisfied thereafter, then either party may, following written notice to the other, extend the End Date in thirty (30) day increments (up to an aggregate of one hundred twenty (120) days); or

(f) By Seller, if at Closing Buyer fails to make the payments required to be made by Buyer at Closing.

Section 9.2 Limitation on Right to Terminate; Effect of Termination.

(a) A party shall not be allowed to exercise any right of termination pursuant to Section 9.1 if the event giving rise to the termination right shall be due to the willful failure of such party seeking to terminate this Agreement to perform or observe in any material respect any of the covenants or agreements hereunder to be performed or observed by such party.

(b) If this Agreement is terminated as permitted under Section 9.1 and except as provided in this Section 9.2(b), such termination shall be without liability of or to any party to this Agreement, or any shareholder or Representative of such party; provided, however, that if such termination shall result from the willful failure of any party to fulfill a condition to the performance of any other party or to perform a covenant of this Agreement or from a material and willful breach by any party to this Agreement (it being understood that the failure to cure a breach shall not, by itself, be a willful breach of this Agreement), then such party shall (subject to the last sentence of this Section 9.2(b)) be fully liable for any and all damages sustained or incurred by the other party; provided, however, if (i) all of Buyer’s and Seller’s conditions precedent to Closing have been satisfied (except with respect to the representations and warranties set forth in Section 4.4), (ii) this Agreement is terminated by Seller pursuant to Section 9.1(d) due to a breach of Buyer’s covenants in Section 6.9 or Section 6.10 of this Agreement, or Section 9.1(e) or Section 9.1(f) of this Agreement and (iii) Buyer is in violation of

its representation in Section 4.4 as measured on such date, then Buyer shall pay to Seller an amount (the “Buyer Termination Fee”) equal to $73,125,000.00, by wire transfer of same day federal funds to the account specified by Seller, within two (2) business days after any such termination. Notwithstanding anything to the contrary in this Agreement, if the Buyer Termination Fee is required to be paid as a result of a termination of this Agreement, Seller’s right to receive the Buyer Termination Fee pursuant to this Section 9.2(b) shall be the sole and exclusive remedy (whether at law, in equity, in contract, in tort or otherwise) of Seller and its Affiliates, as applicable, against Buyer, The Laclede Group, Inc., and their respective Affiliates, and upon payment of the Buyer Termination Fee in accordance with this Section 9.2(b), none of Buyer, The Laclede Group, Inc. and any of their respective stockholders, directors, officers, agents or other representatives, shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement. If prior to Closing either party to this Agreement resorts to legal proceedings to enforce this Agreement, the prevailing party in such proceedings shall be entitled to recover all costs incurred by such party including reasonable attorney’s fees, in addition to any other relief to which such party may be entitled; provided, however, and notwithstanding anything to the contrary in this Section 9.2(b), in no event shall either party be entitled to receive any punitive, exemplary, special, remote, speculative, indirect or consequential damages (including any damages on account of lost profits or opportunities) in connection with any termination of this Agreement.

EMPLOYEE MATTERS

Section 10.1 Employee Agreement. The parties have addressed the transfer of employees and employee benefit matters in a separate agreement, entitled Employee Agreement, executed and delivered as of even date herewith, the terms and provisions of which agreement are incorporated into this Agreement as if fully set forth herein and a copy of which is attached hereto as Exhibit 10.1 (the “Employee Agreement”).

ARTICLE XI

TAX MATTERS

Section 11.1 Purchase Price Allocation. Within one hundred eighty (180) days after the Closing Date, Buyer and Seller shall use their good faith efforts to agree upon the allocation (the “Allocation”) of the Purchase Price (plus Assumed Liabilities, to the extent properly taken into account under the IRC), as adjusted pursuant to Section 3.2, among the Assets for U.S. federal (and applicable state and local) income Tax purposes in accordance with Section 1060 of the IRC and the Treasury Regulations thereunder. If Buyer and Seller are unable to resolve any dispute regarding the Allocation within such one hundred eighty (180) day period, such dispute shall be resolved promptly by the CPA Firm, the costs of which shall be borne equally by Buyer and Seller. If the Purchase Price is adjusted pursuant to this Agreement, the Allocation shall be adjusted as mutually agreed by Buyer and Seller. Buyer and Seller covenant and agree that (a) Buyer and Seller shall file all Tax Returns (including, but not limited to, IRS Form 8594) consistent with the Allocation, and (b) neither Buyer nor Seller will take any Tax position before any Governmental Body or in any Proceeding with respect to Tax that is in any way inconsistent

with such Allocation; provided, however, that nothing contained herein shall prevent Buyer or Seller from settling any proposed Tax deficiency or adjustment by any Governmental Body based upon or arising out of the Allocation, and neither Buyer nor Seller shall be required to litigate before any court any proposed Tax deficiency or adjustment by any Governmental Body challenging such Allocation. Each of Buyer and Seller agrees to provide the other promptly with any other information reasonably required to complete Form 8594 and Form 8883 (and any similar forms required for state or local Tax purposes). Each of Buyer and Seller shall notify the other in the event of an examination, audit or other proceeding regarding the Allocation determined under this Section 11.1.

Section 11.2 Cooperation with Respect to Like-Kind Exchange. Buyer agrees that Seller may, at Seller’s election at or prior to the Closing Date, direct that all or a portion of the Purchase Price be delivered to a “qualified intermediary” (as defined in Treasury Regulation Section 1.1031(k) - 1(g)(4)) identified by Seller (a “Qualified Intermediary”) in order to enable Seller’s relinquishment of the Assets to qualify as part of a like-kind exchange of property covered by Section 1031 of the IRC and any corresponding state income Tax provision. If Seller so elects, Buyer shall cooperate with Seller in connection with Seller’s efforts to effect such like-kind exchange, which cooperation shall include, without limitation, taking such actions as Seller requests in order to enable Seller to qualify such transfer as part of a like-kind exchange of property covered by Section 1031 of the IRC (including any actions required to facilitate the use of a Qualified Intermediary.) Notwithstanding anything herein, the structuring of the transactions in a manner that qualifies the transactions as part of a like-kind exchange shall not be a condition to Closing. Buyer agrees that Seller may assign all or part of its rights and delegate all or part of its obligations under this Agreement to a Qualified Intermediary to qualify the transfer of the Assets as part of a like-kind exchange of property covered by Section 1031 of the IRC and any corresponding state income Tax provision. Any and all representations, obligations, agreements, warranties and covenants made by Seller to Buyer in connection with this Agreement shall remain in full force and effect and continue to inure to the benefit of Buyer, notwithstanding any assignment of this Agreement to a Qualified Intermediary in connection with such Section 1031 exchange. Nothing in this Section 11.2 shall in any manner relieve Seller from any of its obligations under this Agreement, and Seller shall remain primarily liable to Buyer pursuant to the terms of this Agreement. Buyer and Seller agree in good faith to use reasonable efforts to coordinate the transactions contemplated by this Agreement with any other transactions engaged in by either Buyer or Seller; provided that such efforts do not result in an unreasonable delay in the consummation of the transactions contemplated by this Agreement. Buyer’s cooperation and actions taken pursuant to this Section 11.2 shall not increase Buyer’s liabilities or obligations pursuant to the terms of this Agreement, and Seller shall indemnify and hold Buyer harmless from any out-of-pocket cost or expense (including but not limited to legal fees, opinions of counsel or other costs incurred in implementing any transaction under this Section 11.2), or any obligation or liability incurred by Buyer in connection with any action taken by Buyer under this Section 11.2 or such Section 1031 exchange. Notwithstanding anything to the contrary in this Section 11.2, in no event shall Seller transfer title to any of the Assets to any Person other than directly to Buyer or its designee.

Section 11.3 Transaction Taxes. All transfer, documentary, recording, notarial, sales, use, registration, stamp and other similar taxes, fees and expenses (including, but not limited to, all applicable stock transfer, real estate transfer or conveyance Taxes and including any penalties, interest and additions to such tax) (“Transaction Taxes”) incurred in connection with this Agreement and the transactions contemplated hereby shall be borne one-half by Buyer and one-half by Seller, regardless of whether the Tax authority seeks to collect such Taxes from Seller or Buyer. Buyer and Seller shall cooperate in timely making and filing all Tax Returns as may be required to comply with the provisions of laws relating to such Transaction Taxes. Seller shall prepare all tax filings related to any Transaction Taxes, which shall be subject to the reasonable review of Buyer, and also shall notify Buyer of any claimed material exemptions from Transaction Taxes for which no filing is required which shall be subject to the reasonable review of Buyer.

Section 11.4 Real and Personal Property Taxes. All real (including public utility realty tax) and personal property Taxes and assessments arising with respect to the Assets and any similar utility Taxes of any other jurisdiction shall be prorated between Buyer and Seller based on the relative periods of time the Assets were owned by each respective party or their respective Affiliates during the fiscal period for which such Taxes are imposed by the applicable taxing jurisdiction (as such fiscal period is or may be reflected on the bill rendered by such taxing jurisdiction, but in the case of Taxes imposed based on the specific day of ownership of assets or other specified standard not tied to a fiscal period, a fiscal period shall be deemed to be the three hundred sixty five (365) day period ending with such date). Upon receipt by Buyer of the tax bill, invoice or other statement regarding such real and personal property Taxes, Buyer shall calculate the pro rata share of such tax bill, invoice or other statement attributable to Buyer and Seller. To the extent such Taxes have not otherwise been accrued or accounted for in the Base Statement or the Final Closing Statement, Buyer then shall forward, as soon as practicable, to Seller a copy of such tax bill, invoice or statement along with the supporting documentation relating to the calculation of the pro rata share to Seller that had not otherwise been accrued or accounted for in the Base Statement or the Final Closing Statement. Seller then shall forward to Buyer payment of its pro rata share of such Taxes in immediately available funds as soon as practicable and in advance of the due date of the tax bill, invoice or statement and in time to avoid the incurrence of penalties, interest or other increases or additions to such Taxes. In the event Seller first receives a tax bill, invoice or statement relating to the Assets from a taxing authority, Seller shall promptly forward such tax bill, invoice or statement to Buyer.

Section 11.5 Other Taxes. Except as otherwise provided in Sections 11.3 and 11.4, and subject to the provisions and limitations in Article XII, Seller shall indemnify Buyer from and against and in respect of any and all Losses incurred by Buyer, which may be imposed on, sustained, incurred or suffered by or assessed against Buyer, directly or indirectly, to the extent relating to or arising from (a) all Taxes (or the non-payment thereof) of Seller or with respect to the Assets for all taxable periods ending on or before the Closing Date and, with respect to any Straddle Period, the portion of such Straddle Period deemed to end on the Closing Date (“Pre-Closing Tax Period”), (b) all Taxes of any member of an affiliated, consolidated, combined or unitary group of which Seller (or any predecessor of any of the foregoing) is or was a member on or prior to the Closing Date, including pursuant to Treasury Regulation §1.1502-6 or any

analogous or similar state, local, or foreign law or regulation, (c) any and all Taxes of any Person (other than Seller) imposed on Seller as a transferee or successor, by contract (excluding customary Tax indemnification provisions in commercial contracts not primarily relating to Taxes) or pursuant to any law, rule, or regulation, which Taxes relate to an event or transaction occurring before the Closing, and (d) any Taxes of Seller that do not relate to the Business or the Assets purchased pursuant to this Agreement.

Section 11.6 Straddle Period. In the case of any taxable period that includes (but does not end on) the Closing Date (a “Straddle Period”), the amount of any Taxes based on or measured by income or receipts of Seller for the Pre-Closing Tax Period shall be determined based on an interim closing of the books as of the close of business on the Closing Date (and for such purpose, the taxable period of any partnership or other pass-through entity in which Seller holds a beneficial interest shall be deemed to terminate at such time) and the amount of other Taxes of Seller for a Straddle Period that relates to the Pre-Closing Tax Period shall 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 taxable period ending on the Closing Date and the denominator of which is the number of days in such Straddle Period.

Section 11.7 Cooperation on Tax Matters. Buyer and Seller shall cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns pursuant to this Article XI and any audit, litigation or other proceeding with respect to Taxes. Such cooperation shall include the retention and (upon the other Party’s request) the provision of records and information that are reasonably relevant to any such audit, litigation or other proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder.

Section 11.8 Tax Returns. Except as otherwise provided in Sections 11.3 and 11.4,

(a) Seller shall prepare and file or cause to be prepared and filed when due (including extensions) all Tax Returns that are required to be filed by Seller with respect to the Assets for taxable years or periods ending on or before the Closing Date that are due on or before the Closing Date, and Seller shall remit or cause to be remitted any Taxes due in respect of such Tax Returns. All such Tax Returns shall be prepared in a manner consistent with past practice.

(b) Except as provided in Section 11.8(a), Buyer shall prepare and file or cause to be prepared and filed when due all Tax Returns that are required to be filed with respect to the Assets for taxable years or periods ending on or before the Closing Date. At least twenty (20) days prior to filing any such Tax Return, Buyer shall submit a copy of such Tax Return to Seller for Seller’s review. Buyer shall consider in good faith any comment that Seller submits to Buyer no less than ten (10) days prior to the due date of such Tax Returns. Buyer shall remit or cause to be remitted any Taxes due in respect of such Tax Returns.

Section 11.9 Effect of Indemnity Payments. Buyer and Seller hereby agree that any and all indemnity payments made pursuant to this Agreement shall, to the maximum extent permitted by applicable law, be treated for all Tax purposes as an adjustment to the Purchase Price.

Section 11.10 Survival of Obligations. Notwithstanding any other provision of this Agreement, the obligations of Buyer and Seller set forth in this Article XI shall not be subject to any restrictions or limitations other than those expressly set forth in this Article XI and shall survive the Closing.

ARTICLE XII

From and after Closing and subject to the other provisions of this Article XII, Seller shall indemnify and hold harmless Buyer, its Representatives, Affiliates, and each of their successors and permitted assigns (collectively, the “Buyer Indemnitees”) from and against any and all Losses actually incurred by a Buyer Indemnitee, and resulting from:

(a) (i) any representations and warranties made by Seller in this Agreement or in any Related Document not being true and correct when made, or (ii) any representations and warranties made by Seller in this Agreement or any Related Document not being true and correct as of the Closing Date, each of which representations and warranties will be deemed for purposes of this Section 12.1(a)(ii) to have been made by Seller as of the Closing Date, except that those representations and warranties that are made as of a specific date will be deemed for purposes of this Section 12.1(a)(ii) to have been made by Seller as of such specific date;

(b) any breach or default by Seller in the performance of its covenants, agreements, or obligations under this Agreement or any Related Document;

(d) the Excluded Assets.

(b) any breach or default by Buyer in the performance of its covenants, agreements, or obligations under this Agreement or any Related Document; and

Section 12.3 Limitations on Seller’s Liability. Notwithstanding anything to the contrary in this Agreement, the liability of Seller under this Agreement and any documents delivered in connection herewith or contemplated hereby shall be limited as follows:

(a) EXCEPT TO THE EXTENT ARISING OUT OF FRAUD, CRIMINAL MISREPRESENTATION OR WILLFUL MISCONDUCT, IN NO EVENT SHALL SELLER BE LIABLE TO THE BUYER INDEMNITEES FOR ANY EXEMPLARY, PUNITIVE, SPECIAL, INDIRECT, CONSEQUENTIAL, REMOTE OR SPECULATIVE DAMAGES; provided, however, that if Buyer is held liable to a third party for any of such damages and Seller is obligated to indemnify Buyer for the matter that gave rise to such damages, then Seller shall be liable for, and obligated to reimburse Buyer for, such damages.

(b) Except as provided below, the representations and warranties of Seller set forth in this Agreement or any Related Document shall survive the Closing until the date that is twenty-four (24) months after the Closing Date; provided however, that (i) the representations and warranties set forth in Section 5.1 (Organization, Existence and Qualification), Section 5.2 (Authority Relative to this Agreement and Binding Effect), in the first and last sentences of Section 5.4(a) (Title to Assets; Encumbrances), and in Section 5.17 (Brokers) shall survive indefinitely, and (ii) the representations and warranties set forth in Sections 5.8 (Taxes), 5.12 (Employee Benefit Matters) and 5.13 (Employee and Labor Matters) and in the Employee Agreement shall survive for a period equal to the applicable statute of limitations (giving effect to any extensions or waivers thereof). The other terms of this Agreement and the Related Documents, including the covenants and agreements made in connection herewith and therewith, shall survive the Closing. All representations and warranties, covenants and agreements of Seller under this Agreement and the indemnities granted by Seller in Section 12.1 shall terminate at 5:00 p.m., Central time, on the applicable survival termination date set forth above; provided, however, that such indemnities shall continue to survive with respect only to any specific matter that is the subject of a proper Claim Notice delivered in good faith in compliance with the requirements of this Section 12.3 until the earlier to occur of (i) the date on which a final nonappealable resolution of the matter described in such Claim Notice has been reached, including the determination of all related Losses, if any, regardless of when such Losses are finally determined or (ii) the date on which the matter described in such Claim Notice has otherwise reached final resolution, including the determination of all related Losses, if any, regardless of when such Losses are finally determined. In no event shall any amounts be recovered from Seller under Section 12.1 or otherwise for any matter for which a Claim Notice is not delivered to Seller prior to the close of business on the applicable expiration date set forth above.

(c) Notwithstanding anything to the contrary in this Agreement, in no event shall Seller indemnify the Buyer Indemnitees, or be otherwise liable in any way whatsoever to the Buyer Indemnitees, for any Losses (determined after giving effect to the other provisions of this Section 12.3) otherwise subject to indemnification by Seller pursuant to Section 12.1(a) (other than in respect of any claim for any inaccuracy or breach (or deemed inaccuracy or

breach) of the representations and warranties contained in Section 5.4(a), which claims shall not be subject to the limitations set forth in this Section 12.3(c)) until the Buyer Indemnitees have incurred Losses otherwise indemnifiable pursuant to Section 12.1(a) that in the aggregate exceed $10,000,000.00 (the “Deductible”), after which Seller shall then be liable for all Losses incurred by the Buyer Indemnitees that are indemnifiable pursuant to Section 12.1(a) in excess of such amount up to the maximum amount set forth in Section 12.3(d). Losses subject to indemnification by Seller pursuant to Section 12.1(a) (other than in respect of any claim for any inaccuracy or breach (or deemed inaccuracy or breach) of the representations and warranties contained in Section 5.4(a)) relating to any single breach or series of related breaches by Seller shall not constitute Losses, and therefore shall not be applied toward the Deductible or be indemnifiable hereunder, unless such Losses relating to any single breach or series of related breaches exceed $100,000.00. For purposes of this Section 12.3, the Losses resulting from any breach of the representations and warranties of Seller (other than the representations and warranties of Seller in Section 5.11 and the last sentence of Section 5.15) shall be determined without regard to the effect of any qualifications relating to materiality or Material Adverse Effect (it being understood that such qualifications shall not be disregarded for purposes of determining whether or not any breaches of such representations or warranties have occurred).

(d) Notwithstanding anything to the contrary in this Agreement, (i) in no event shall Seller indemnify the Buyer Indemnitees, or be otherwise liable in any way whatsoever to the Buyer Indemnitees, for any Losses (determined after giving effect to the other provisions of this Section 12.3) otherwise subject to indemnification by Seller pursuant to Section 12.1(a) (other than in respect of any claim for any inaccuracy or breach (or deemed inaccuracy or breach) of the representations and warranties contained in Section 5.4(a)) that in the aggregate exceed $100,000,000.00, and (ii) in no event shall Seller indemnify the Buyer Indemnitees, or be otherwise liable in any way whatsoever to the Buyer Indemnitees, for any Losses (determined after giving effect to the other provisions of this Section 12.3) otherwise subject to indemnification by Seller pursuant to Section 12.1(a) (solely in respect of any claim for any inaccuracy or breach (or deemed inaccuracy or breach) of the representations and warranties contained in Section 5.4(a)) that in the aggregate exceed the Purchase Price.

(e) Seller shall have no liability for the portion of any claim or Loss for which Buyer has recovered or has been specifically authorized to recover through rates; provided, however, that Buyer shall have made a good faith effort to recover any such claim or Loss through rates and that such recovery is not indeterminable due to the terms of any rate settlement agreed to by Buyer. No cost or expense relating to any such claim or Loss that is actually recovered on the basis of the foregoing shall be included in determining the extent of Losses suffered by the Buyer Indemnitees for purposes of Section 12.3(c) or Section 12.3(d). If at any time subsequent to the receipt by a Buyer Indemnitee of an indemnity payment from Seller hereunder, such Buyer Indemnitee (or any Affiliate thereof) receives any recovery, settlement or other similar payment with respect to the Loss for which it receives such indemnity payment, such Buyer Indemnitee shall promptly pay to Seller an amount equal to the amount of such recovery, less any expense incurred by such Buyer Indemnitee (or its Affiliates) in connection with such recovery, but in no event shall any such payment exceed the amount of such indemnity payment.

(f) Seller shall have no liability for the portion of any claim or Loss to the extent (but only to the extent) the liability for such Loss was reflected in Net Assets and taken into account in determining the Final Purchase Price.

(g) Notwithstanding any language contained in any Related Document (including deeds and other conveyance documents relating to the Real Property), any representations and warranties of Seller set forth in any Related Document, the indemnification obligations of Seller, and the limitations on such obligations, set forth in this Agreement shall control. No provision set forth in any such Related Document shall be deemed to enlarge, alter or amend the terms or provisions of this Article XII.

Section 12.4 Limitation on Buyer’s Liability. EXCEPT TO THE EXTENT ARISING OUT OF FRAUD, CRIMINAL MISREPRESENTATION OR WILLFUL MISCONDUCT, IN NO EVENT SHALL BUYER BE LIABLE TO THE SELLER INDEMNITEES FOR ANY EXEMPLARY, PUNITIVE, SPECIAL, REMOTE OR SPECULATIVE DAMAGES; provided, however, that if Seller is held liable to a third party for any of such damages and Buyer is obligated to indemnify Seller for the matter that gave rise to such damages, then Buyer shall be liable for, and obligated to reimburse Seller for, such damages.

Section 12.5 Claims Procedure.

(a) All claims for indemnification under Section 12.1 or 12.2, or any other provision of this Agreement except as otherwise expressly provided in this Agreement, shall be asserted and resolved pursuant to this Article XII. Any Person claiming indemnification hereunder is referred to as the “Indemnified Party” and any Person against whom such claims are asserted hereunder is hereinafter referred to as the “Indemnifying Party.” In the event that any Losses are asserted against or sought to be collected from or Threatened to be sought from an Indemnified Party by a third party, including a Governmental Body, said Indemnified Party shall with reasonable promptness provide to the Indemnifying Party a Claim Notice. If the Indemnified Party fails to notify the Indemnifying Party of any Losses in accordance with the provisions of this Article XII in reasonably sufficient time such that the Indemnifying Party’s ability to defend against the Losses is prejudiced, then the Indemnifying Party shall not be obligated to indemnify the Indemnified Party with respect to such Losses to the extent (but only to the extent) of such prejudice. The Indemnifying Party shall have thirty (30) days from the personal delivery or receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party (i) whether or not it disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such Losses and/or (ii) whether or not it desires, at the sole cost and expense of the Indemnifying Party, to defend the Indemnified Party against such Losses; provided, however, that any Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading that it shall reasonably deem necessary or appropriate to protect its interests or those of the Indemnifying Party (and of which it shall have given notice and opportunity to comment to the Indemnifying Party) and not prejudicial to the Indemnifying Party. In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against

such Losses and expressly confirms in writing its obligation to indemnify and hold harmless the Indemnified Party for the Losses that are reasonably likely to result from such claim, the Indemnifying Party shall have the right to defend all appropriate proceedings, and with counsel reasonably acceptable to the Indemnified Party, which proceedings shall be promptly settled or prosecuted by them to a final conclusion. If the Indemnified Party desires to participate in, but not control, any such defense or settlement, it may do so at its sole cost and expense; provided, however, that the participation of such claim by counsel selected by the Indemnifying Party will not, in the reasonable judgment of counsel to the Indemnified Party, create a conflict or potential conflict of interest between such parties. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any Losses that the Indemnifying Party elects to contest or, if appropriate and related to the claim in question, in making any counterclaim against the Person asserting the third party Losses, or any cross-complaint against any Person. No claim may be settled or otherwise compromised without the prior written consent of both the Indemnifying Party and the Indemnified Party; provided, however, that the Indemnifying Party may pay, compromise, settle or otherwise dispose of any claim without the prior written consent of the Indemnified Party only if (i) such settlement involves only the payment of money, (ii) such payment is made in full solely by the Indemnifying Party without recourse to the Indemnified Party, and (iii) such settlement does not impose any obligations or restrictions on the Indemnified Party of any nature. In no event will the Indemnifying Party have the authority to agree, without the consent of the Indemnified Party, to any relief binding on the Indemnified Party other than the payment of money damages by the Indemnifying Party without recourse to the Indemnified Party.

(b) The Indemnified Party shall provide reasonable assistance to the Indemnifying Party and provide access to its books, records and personnel as the Indemnifying Party reasonably requests in connection with the investigation or defense of the Losses. The Indemnifying Party shall promptly, upon receipt of reasonable supporting documentation, reimburse the Indemnified Party for out-of-pocket costs and expenses incurred by the latter in providing the requested assistance.

(c) With regard to third party claims for which Buyer or Seller is entitled to indemnification under Section 12.1 or 12.2, such indemnification shall be paid by the Indemnifying Party upon (i) the entry of an Order against the Indemnified Party and the expiration of any applicable appeal period or (ii) a settlement with the consent of the Indemnifying Party, provided that no such consent need be obtained if the Indemnifying Party fails to respond to the Claim Notice as provided in Section 12.5(a). Notwithstanding the foregoing but subject to Section 12.5(a), and provided that there is no dispute as to the applicability of indemnification, expenses of counsel to the Indemnified Party shall be reimbursed on a current basis by the Indemnifying Party as if such expenses are a liability of the Indemnifying Party.

Section 12.6 Exclusive Remedy. Except (i) for claims arising out of fraud, criminal misrepresentation, or willful misconduct, and (ii) as otherwise provided in Sections 2.4(b), 2.4(c), 3.2(b), 6.1(c)(i), 6.2(b), 6.4, 6.10(b), 9.2, 11.2 and 11.5, the rights, remedies and obligations of the Buyer Indemnitees and the Seller Indemnitees set forth in this Article XII will

be the exclusive rights, remedies and obligations of such Persons after the Closing with respect to all post-Closing claims relating to this Agreement, the events giving rise to this Agreement and the transactions provided for herein or contemplated hereby or thereby. Except for claims arising out of fraud, criminal misrepresentation or willful misconduct, no Proceeding for termination or rescission, or claiming repudiation, of this Agreement may be brought or maintained by either party against the other following the Closing Date no matter how severe, grave or fundamental any breach, default or nonperformance may be by one party. Accordingly, except as otherwise provided in this Section 12.6, the parties hereby expressly waive and forego any and all rights they may possess to bring any such Proceeding.

Section 13.3 Assignment. This Agreement may not be assigned, by operation of law or otherwise, by any party hereto without the prior written consent of the other party hereto, such consent not to be unreasonably withheld or delayed. Notwithstanding the foregoing, Seller may assign all or part of its rights or delegate all or part of its duties under this Agreement, without the prior written consent of Buyer, to a Qualified Intermediary chosen by Seller to structure all or part of the transactions contemplated hereby as a like-kind exchange of property covered by

Section 1031 of the IRC; provided that no such assignment or delegation shall relieve Seller of its obligations hereunder, and Seller shall remain primarily liable to Buyer pursuant to the terms of this Agreement.

Section 13.4 Successor Bound. Subject to the provisions of Section 13.3, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns.

Section 13.5 Governing Law. The validity, performance, and enforcement of this Agreement, all Related Documents and the transactions contemplated hereby and thereby, unless expressly provided to the contrary, shall be governed by the laws of the State of Delaware without giving effect to the conflicts of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

Section 13.6 Construction of Agreement. The terms and provisions of this Agreement represent the results of negotiations between Buyer and Seller, each of which has been represented by counsel of its own choosing, and neither of which has acted under duress or compulsion, whether legal, economic or otherwise. Accordingly, the terms and provisions of this Agreement shall be interpreted and construed in accordance with their usual and customary meanings, and Buyer and Seller hereby waive the application in connection with the interpretation and construction of this Agreement of any rule of law to the effect that ambiguous or conflicting terms or provisions contained in this Agreement shall be interpreted or construed against the party whose attorney prepared the executed draft or any earlier draft of this Agreement. It is understood and agreed that neither the specification of any dollar amount in the representations and warranties contained in this Agreement nor the inclusion of any specific item in the Schedules or Exhibits is intended to imply that such amounts or higher or lower amounts, or the items so included or other items, are or are not material, and none of the parties shall use the fact of the setting of such amounts or the fact of any inclusion of any such item in the Schedules or Exhibits in any dispute or controversy between the parties as to whether any obligation, item or matter is or is not material for purposes hereof; provided, however, that all contracts included on Schedule 5.11 are Material Contracts. The word “including” in this Agreement shall mean including without limitation. Words in the singular shall be held to include the plural and vice versa and words of one gender shall be held to include the other genders as the context requires. The terms “hereof,” “herein,” and “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole (including all of the Schedules and Exhibits hereto) and not to any particular provision of this Agreement, and Article, Section, paragraph, Exhibit and Schedule references are to the Articles, Sections, paragraphs, Exhibits and Schedules to this Agreement unless otherwise specified.

Section 13.7 Publicity. Neither party hereto, nor any of their respective Affiliates or Representatives, shall issue, make or cause the publication of any press release or other announcement with respect to this Agreement or the transactions contemplated hereby, or otherwise make any disclosures relating thereto, without the consent of the other party, such consent not to be unreasonably withheld or delayed; provided, however, that such consent shall

not be required where such release or announcement is required by applicable law or the rules or regulations of a securities exchange, in which event the party so required to issue such release or announcement shall endeavor, wherever possible, to furnish an advance copy of the proposed release to the other party.

Section 13.8 Waiver. Except as otherwise expressly provided in this Agreement, neither the failure nor any delay on the part of any party to exercise any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise or waiver of any such right, power or privilege preclude any other or further exercise thereof, or the exercise of any other right, power or privilege available to each party at law or in equity. The rights and remedies of the parties hereunder are cumulative and are not exclusive of any rights or remedies which they would otherwise have hereunder.

Section 13.9 Parties in Interest. This Agreement (including the documents and instruments referred to herein) is not intended to confer upon any Person, other than the parties hereto and their successors and permitted assigns, any rights or remedies hereunder; provided, however, that the indemnification provisions in Article XII shall inure to the benefit of, and be enforceable by, the Buyer Indemnitees and the Seller Indemnitees as provided therein. Without limiting the foregoing, no provision of this Agreement (including the documents and instruments referred to herein) creates any rights in any employee or former employee of Seller (including any beneficiary or dependent thereof) in respect of continued employment or resumed employment, and no provision of this Agreement creates any rights in any such Persons in respect of any benefits that may be provided, directly or indirectly, under any employee benefit plan or arrangement; provided, further, that notwithstanding anything to the contrary in this Section 13.9, each of this Section 13.9, Section 13.15, Section 13.17 and Section 13.20 is intended to benefit, and be enforceable by, the Financing Sources and their stockholders, partners and members.

Section 13.10 Section and Paragraph Headings. The section and paragraph headings in this Agreement are for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement.

Section 13.11 Amendment. This Agreement may be amended only by an instrument in writing executed and delivered by the parties hereto.

Section 13.12 Entire Agreement. This Agreement, the Exhibits and Schedules hereto and the documents specifically referred to herein and the Confidentiality Agreement constitute the entire agreement, understanding, representations and warranties of the parties hereto, and supersede all prior agreements, both written and oral, between Buyer and Seller. All Exhibits and Schedules annexed hereto or referred to herein are hereby incorporated in and made a part of this Agreement as if set forth in full herein. Disclosure of any fact or item in any Schedule referenced by a particular paragraph or Section in this Agreement shall, should the existence of the fact or item or its contents be relevant to any other paragraph or Section, be deemed to be disclosed with respect to that other paragraph or Section whether or not any explicit cross-reference appears therein but only to the extent that such relevance is clearly and readily apparent from the face of such disclosure; provided, however, that notwithstanding the foregoing, no disclosures shall be deemed to be disclosed on Schedule 5.20 except for such disclosures explicitly set forth thereon or explicitly incorporated by reference into Schedule 5.20.

Section 13.13 Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original, and all of which together shall constitute one and the same instrument.

Section 13.14 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that transactions contemplated hereby are fulfilled to the greatest extent possible.

Section 13.15 Consent to Jurisdiction. The parties hereby irrevocably submit to the exclusive jurisdiction of the state and federal courts located in the State of Delaware over any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby, and each party irrevocably agrees that all claims in respect of such dispute or proceeding shall be heard and determined in such courts. The parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any objection which they may now or hereafter have to the 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 inconvenient forum 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 applicable law. Notwithstanding anything in this Agreement to the contrary and without limitation of the rights of the Financing Sources set forth in Section 13.20, the parties hereby agree that they will not bring or support, or permit any of their Affiliates or Representatives to bring or support, any action, cause of action, claim, cross-claim or third-party claim of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against any Financing Source (or any Financing Source’s stockholders, partners and members) in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including but not limited to any dispute arising out of or relating in any way to the Financing or the performance thereof, in any forum other than the Supreme Court of the State of New York, County of New York, or if under applicable law exclusive jurisdiction is vested in the Federal courts, the United States District Court for the Southern District of New York (and appellate courts thereof), and hereby irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of, and the defense of an inconvenient forum to the maintenance of, any such action in any such court.

Section 13.16 Enforcement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each of the parties shall be

entitled to specific performance of the terms hereof, including an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in any state or federal court located in the State of Delaware, this being in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereto further hereby waives (a) any defense in any action for specific performance that a remedy at law would be adequate and (b) any requirement under any law to post security as a prerequisite to obtaining equitable relief.

Section 13.17 Waiver of Jury Trial. EACH OF THE PARTIES TO THIS AGREEMENT HEREBY IRREVOCABLY WAIVES ALL RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY, INCLUDING ANY ACTION OR PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF UNDER OR IN CONNECTION WITH THE FINANCING OR ANY CLAIM OR PROCEEDING INVOLVING THE FINANCING SOURCES.

Section 13.18 Time of Essence. This Agreement contains a number of dates and times by which performance or the exercise of rights is due, and the parties hereto intend that each and every such date and time be the firm and final date and time, as agreed. For this reason, each party hereto hereby waives and relinquishes any right it might otherwise have to challenge its failure to meet any performance or rights election date applicable to it on the basis that its late action constitutes substantial performance, to require the other party to show prejudice, or on any equitable grounds. Without limiting the foregoing, time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date which is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day which is a Business Day.

Section 13.19 Guarantee. The Laclede Group, Inc. agrees to take all action necessary to cause Buyer to perform all of its respective agreements, covenants and obligations under this Agreement and the Related Documents. The Laclede Group, Inc. unconditionally guarantees to Seller the full and complete performance by Buyer of its respective obligations under this Agreement. This is a guarantee of payment and performance and not of collectability. The Laclede Group, Inc. hereby waives diligence, presentment, demand of performance, filing of any claim, any right to require any proceeding first against Buyer, protest, notice and all demands whatsoever in connection with the performance of its obligations set forth in this Section 13.19.

Section 13.20 Financing Sources. Notwithstanding anything in this Agreement to the contrary, neither the Seller, nor any of its stockholders, partners, members, Affiliates or Representatives, and each of their successors and permitted assigns shall have, and the Seller hereby waives, any rights or claims against each of the Financing Sources and each of the Financing Source’s respective stockholders, partners and members, in connection with this Agreement or the Financing, whether at law or equity, in contract in tort or otherwise. Without limiting the foregoing, the Financing Sources shall be beneficiaries of all limitations on remedies

and damages in this Agreement that apply to Buyer hereto and are express third party beneficiaries of this Section 13.20 (which may not be changed without the Financing Sources’ prior written consent).

IN WITNESS WHEREOF, the parties have caused this Agreement to be executed and delivered by their duly authorized officers as of the date first written above.
