3.2.	Determination of Adjustment Amount and Purchase Price.

(a) No later than fifteen (15) days prior to the Closing Date, Seller, in consultation with Parent and Buyer, will prepare and deliver to Buyer and Parent, Seller’s best estimate of the Actual Working Capital, the Actual Capital Expenditures, the Unrecovered Purchased Gas Adjustments, the Lease Buy-Out Amount, the Adjustment Amount and the Purchase Price to be paid at the Closing, based on Seller’s best estimates of the Adjustment Amount (such estimated Purchase Price being referred to herein as the “Closing Payment Amount”).

(b) Within ninety (90) days after the Closing Date, Buyer will prepare and deliver to Parent a statement (the “Proposed Adjustment Statement”) that reflects Buyer’s determination of (i) the Actual Working Capital, the Actual Capital Expenditures, the Unrecovered Purchased Gas Adjustments, the Lease Buy-Out Amount and the Adjustment Amount (the “Proposed Adjustment Amount”), and (ii) the Purchase Price based on the Proposed Adjustment Amount (the “Proposed Purchase Price”). In addition, Buyer will provide Parent with supporting assumptions and calculations, in reasonable detail, for such determinations at the time it delivers the Proposed Adjustment Statement. Parent and Seller agree to, and Parent

1-LA/903877.26

agrees to cause Seller’s successor to, cooperate with Buyer after the Closing in connection with the preparation of the Proposed Adjustment Statement and related information, and will provide Buyer with access to Seller’s books, records, information, and employees that are primarily related to the Business and the Purchased Assets that are in Seller’s or its successor’s possession or control as Buyer may reasonably request.

(c) The amounts determined by Buyer as set forth in the Proposed Adjustment Statement will be final, binding, and conclusive for all purposes unless, and only to the extent, that within thirty (30) days after Buyer has delivered the Proposed Adjustment Statement, Parent notifies Buyer of any dispute with matters set forth in the Proposed Adjustment Statement. Any such notice of dispute delivered by Parent (an “Adjustment Dispute Notice”) will identify with reasonable specificity each item in the Proposed Adjustment Statement with respect to which Parent disagrees, the reason for such disagreement, and Parent’s position with respect to such disputed item, and will include Parent’s recalculation of the Adjustment Amount and the Purchase Price. Parent shall be conclusively deemed to have accepted any item in the Proposed Adjustment Statement not addressed by the Adjustment Dispute Notice.

(d) If Parent delivers an Adjustment Dispute Notice in compliance with Section 3.2(c), Buyer and Parent will attempt to reconcile their differences and any resolution by them as to any disputed amounts will be final, binding, and conclusive for all purposes on the Parties. If Buyer and Parent are unable to reach a resolution with respect to all disputed items within forty five (45) days of delivery of the Adjustment Dispute Notice, Buyer and Parent will submit any items remaining in dispute for determination and resolution to the Independent Accounting Firm, which will be instructed to determine and report to the Parties, within thirty (30) days after such submission, upon such remaining disputed items. The determination of the Independent Accounting Firm on each issue shall be neither more favorable to Buyer than shown in the Proposed Adjustment Statement nor more favorable to Parent than shown in the Adjustment Dispute Notice. The report of the Independent Accounting Firm will identify the correct Actual Working Capital, Actual Capital Expenditures, Unrecovered Purchased Gas Adjustments, Lease Buy-Out Amount, Adjustment Amount and Purchase Price (the “Correct Purchase Price”) and such report will be final, binding, and conclusive on the Parties for all purposes. The fees and disbursements of the Independent Accounting Firm will be allocated between Buyer and Parent so that Parent’s share of such fees and disbursements will be in the same proportion that the aggregate amount of such remaining disputed items so submitted to the Independent Accounting Firm that is unsuccessfully disputed by Parent (as finally determined by the Independent Accounting Firm) bears to the total amount of the disputed amounts so submitted to the Independent Accounting Firm, with the remaining amount allocated to Buyer.

(e) “Final Purchase Price” shall mean (i) the Proposed Purchase Price, if Parent does not deliver an Adjustment Dispute Notice; (ii) the amount agreed between Parent and Purchaser, if any; or (iii) the Correct Purchase Price, if determined by the Independent Accounting Firm. Within five (5) days following the final determination of the Final Purchase Price pursuant to Sections 3.2(b), (c) and (d), (x) if the Final Purchase Price is greater than the Closing Payment Amount, Buyer will pay the difference to Seller or its successor; or (y) if the Final Purchase Price is less than the Closing Payment Amount, Parent will cause Seller, or its successor, to pay the difference to Buyer. Any amount paid under this Section 3.2(e) will be paid with interest for the period commencing on the Closing Date through the date of payment,

1-LA/903877.26

calculated at the Prime Rate in effect on the Closing Date, in cash by wire transfer of same day funds to the account specified by the Party receiving payment.

3.3. Allocation of Purchase Price. The sum of the Purchase Price and the Assumed Obligations will be allocated among the Purchased Assets on a basis consistent with section 1060 of the Code and the Treasury regulations promulgated thereunder. Within one hundred eighty (180) days following the Closing Date, the Parties will work together in good faith to agree upon such allocation; provided that in the event that such agreement has not been reached within such 180-day period, the allocation will be determined by the Independent Accounting Firm, and such determination will be binding on the Parties.

1-LA/903877.26

to the condition such Real Property was in prior to any investigation of environmental matters), (C) Seller will not be required to take any action which would constitute a waiver of the attorney-client privilege, and (D) Seller need not supply Buyer with any information which Seller is under a contractual or other legal obligation not to supply; provided, however, if Seller relies upon clauses (C) or (D) as a basis for withholding information from disclosure to Buyer, to the fullest extent possible without causing a waiver of the attorney-client privilege, or a violation of a contractual or legal obligation, as the case may be, Seller will provide Buyer with a description of the information withheld and the basis for withholding such information. Notwithstanding anything in this Section 8.2 to the contrary, (x) Buyer will not have access to personnel and medical records if such access could, in Seller’s good faith judgment, subject Seller to risk of liability or otherwise violate the Health Insurance Portability and Accountability Act of 1996, and (y) any investigation of environmental matters by or on behalf of Buyer will be limited to visual inspections and site visits commonly included in the scope of “Phase 1” level environmental inspections, and Buyer will not have the right to perform or conduct any other sampling or testing at, in, on, or underneath any of the Purchased Assets. Seller acknowledges and agrees that except for the information disclosed in Schedules 1.1-B, 3.1(a), 5.3(b), 5.5(a), 5.5(b), 5.8, 5.10(b), 5.10(c), 5.11, 5.14, 8.8(d)(ii)(D) and 8.8(d)(ii)-A to this Agreement, Buyer may include such information relating to the Business and the Purchased Assets as reasonably necessary in filings with the SEC, including in one or more registration statements filed by Buyer in connection with obtaining the Buyer Financing.

(b) Unless and until the transactions contemplated hereby have been consummated, Buyer will, and will cause its Affiliates and Buyer’s Representatives to, hold in strict confidence and not use or disclose to any other Person all Confidential Information. “Confidential Information” means all information in any form heretofore or hereafter obtained from Seller in connection with Buyer’s evaluation of the Business or the negotiation of this Agreement, whether pertaining to financial condition, results of operations, methods of operation or otherwise, other than information which is in the public domain through no violation of this Agreement or the Confidentiality Agreement by Buyer, its Affiliates, or Buyer’s Representatives. Notwithstanding the foregoing, Buyer may disclose Confidential Information to the extent that such information is required to be disclosed by Buyer by Law or in connection with any proceeding by or before a Governmental Entity, including any disclosure, financial or otherwise, required to comply with any SEC rules. In the event that Buyer believes any such disclosure is required, Buyer will give Seller notice thereof as promptly as possible and will cooperate with Seller in seeking any protective orders or other relief as Seller may determine to be necessary or desirable. In no event will Buyer make or permit to be made any disclosure of Confidential Information other than to the extent Buyer’s legal counsel has advised in writing is required by Law, and Buyer will use its reasonable best efforts to assure that any Confidential Information so disclosed is protected from further disclosure to the maximum extent permitted by Law. If the transactions contemplated hereby are not consummated, Buyer will promptly upon Seller’s request, destroy or return to Seller all copies of any Confidential Information, including any materials prepared by Buyer or Buyer’s Representatives incorporating or reflecting Confidential Information, and an officer of Buyer shall certify in writing compliance by Buyer with the foregoing. Seller acknowledges and agrees that this Agreement (other than the information disclosed in Schedules 1.1-B, 3.1(a), 5.3(b), 5.5(a), 5.5(b), 5.8, 5.10(b), 5.10(c), 5.11, 5.14, 8.8(d)(ii)(D) and 8.8(d)(ii)-A to this Agreement) shall not be considered Confidential Information for purposes of this Section 8.2(b).

1-LA/903877.26

(c) Seller agrees that for the two-year period immediately following the Closing Date, Seller will, and will cause its Affiliates and Seller’s Representatives to, hold in strict confidence and not disclose to any other Person all Confidential Business Information. “Confidential Business Information” means all commercially sensitive information in any form heretofore or hereafter obtained by Seller to the extent relating to the Business or the Purchased Assets, whether pertaining to financial condition, results of operations, methods of operation or otherwise, other than information which is in the public domain through no violation of this Agreement. Notwithstanding the foregoing, Seller may disclose Confidential Business Information to the extent that such information is required to be disclosed under contracts existing as of the Closing Date, by Law, or in connection with any proceeding by or before a Governmental Entity, including any disclosure, financial or otherwise, required to comply with any SEC rules or Required Regulatory Approvals. In the event that Seller believes any such disclosure is required by Law or in connection with any proceeding by or before a Governmental Entity, Seller will give Buyer notice thereof as promptly as possible and will cooperate with Buyer in seeking any protective orders or other relief as Buyer may determine to be necessary or desirable. In no event will Seller make or permit to be made any disclosure of Confidential Business Information other than to the extent Seller determines in good faith to be required pursuant to SEC rules, or rules governing required disclosure in other regulatory proceedings, or its legal counsel has advised is required to comply with the terms of a contract existing as of the Closing Date or required by Law, or is required in connection with any proceeding by or before a Governmental Entity, and Seller will use its reasonable best efforts to assure that any Confidential Business Information so disclosed is protected from further disclosure.

(d) The provisions of Section 8.2(b) supersede the provisions of the Confidentiality Agreement relating to Proprietary Information (as defined therein), and will survive for a period of two (2) years following the earlier of the Closing or the termination of this Agreement, except that if the Closing occurs, the provisions of Section 8.2(b) will expire with respect to any information principally related to the Purchased Assets and the Business.

(e) For a period of seven (7) years after the Closing Date, each Party and its representatives will have reasonable access to all of the books and records relating to the Business or the Purchased Assets, including all Transferred Employee Records, in the possession of the other Party to the extent that such access may reasonably be required by such Party in connection with the Assumed Obligations or the Excluded Liabilities, or other matters relating to or affected by the operation of the Business and the Purchased Assets. Such access will be afforded by the Party in possession of such books and records upon receipt of reasonable advance notice and during normal business hours; provided, however, that (i) any review of books and records will be conducted in such a manner as not to interfere unreasonably with the operation of the business of any Party or its Affiliates, (ii) no Party will be required to take any action which would constitute a waiver of the attorney-client privilege, and (iii) no Party need supply any other Party with any information which such Party is under a contractual or other legal obligation not to supply. The Party exercising the right of access hereunder will be solely responsible for any costs or expenses incurred by it pursuant to this Section 8.2(e) and will reimburse the other Party for any costs or expenses incurred by such other Party in connection with complying with such request. If the Party in possession of such books and records desires to dispose of any such books and records prior to the expiration of such seven-year period, such Party will, prior to such disposition, give the other Party a reasonable opportunity at such other

1-LA/903877.26

Party’s expense to segregate and take possession of such books and records as such other Party may select.

8.3. Expenses. Except to the extent specifically provided herein, in the Merger Agreement or in the Partnership Interests Purchase Agreement, and irrespective of whether the transactions contemplated hereby are consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby will be borne by the Party incurring such costs and expenses.

8.4.	Further Assurances; Regulatory Filings; Consents and Approvals.

1-LA/903877.26

transactions contemplated by this Agreement as required by the terms of any note, bond, mortgage, indenture, deed of trust, license, franchise, permit, concession, contract, lease, Business Agreement, Easement, or other instrument to which Seller or Buyer is a party or by which either of them is bound. Buyer and Seller will each have the right to review in advance all characterizations of the information related to it or the transactions contemplated hereby which appear in any filing made by the other in connection with the transactions contemplated by this Agreement. Buyer will be solely responsible for payment of all filing fees required in connection with any Required Regulatory Approvals or such other applications, notices, petitions and filings made with any Governmental Entity.

(d) To the extent permitted by Law, Buyer and Seller will have the right to review in advance, and each will consult the other on, the form, substance and content of any filing to be made by Buyer or Seller or any of their respective Subsidiaries with, or any other written materials submitted by any of them to, any third party or any Governmental Entity (other than the SEC) in connection with the transactions contemplated by this Agreement, the Merger and the Partnership Interests Purchase Agreement. To the extent permitted by Law, each of Buyer and Seller will (i) provide the other with copies of all correspondence between it or any of its Subsidiaries (or its or their Representatives) and any Governmental Entity (other than the SEC) relating to the transactions contemplated by this Agreement, the Merger Agreement and the transactions contemplated by the Partnership Interests Purchase Agreement, (ii) consult and cooperate with the other Party, and to take into account the comments of such other Party in connection with any such filings, and (iii) inform the other Party in advance of any communication, meeting, or other contact which such Party proposes or intends to make with respect to such filings, including the subject matter, contents, intended agenda, and other aspects of any of the foregoing and to use reasonable best efforts to ensure that all telephone calls and meetings with a Governmental Entity regarding the transactions contemplated by this Agreement will include representatives of Buyer and Seller; provided that nothing in the foregoing will apply to or restrict communications or other actions by Seller with or with regard to Governmental Entities in connection with the Purchased Assets or the Business in the ordinary course of business. To the extent permitted by Law, Buyer, Seller and Parent each agree to (1) provide one another with copies of any registration statements filed with the SEC, in the case of Buyer, in connection with obtaining financing, or by Seller and Parent in connection with the transactions contemplated under the Merger Agreement, (2) provide the other Parties the opportunity to review in advance and consult with one another as to the content of such registration statements regarding such Parties and, (3) provide the other Parties with copies of all correspondence between it or any of its Subsidiaries (or its or their respective Representatives) and the SEC with respect to such registration statements regarding such Parties.

(e) Nothing in this Section 8.4(e) will require, or be construed to require, (i) Seller to take or refrain from taking, or to cause any of its Subsidiaries to take or refrain from taking, any action or to engage in any conduct, or to agree or consent to Seller or any of its Subsidiaries taking any action or engaging in any conduct, or agreeing to any restriction, condition or conduct, with respect to any of the businesses, assets or operations of Seller or any of its Subsidiaries, if this action, restriction, condition or conduct would take effect prior to the Closing or is not conditioned on the Closing occurring, or (ii) Buyer to take or refrain from taking, or to cause any of its Subsidiaries to take or refrain from taking, any action or to engage in any conduct, or to agree or consent to Seller or any of its Subsidiaries taking any action, or agreeing to any restriction, condition or conduct, with respect to any of the businesses, assets or

1-LA/903877.26

operations of Seller or any of its Subsidiaries, if the cumulative impact of these actions, restrictions, conditions and conduct would reasonably be expected to have a material adverse effect on the financial condition, properties, assets, liabilities (contingent or otherwise), business or results of operations of the Business and the Purchased Assets, together with the Colorado Business and the Colorado Assets, taken as a whole (a “Regulatory Material Adverse Effect”), it being understood that, for purposes of determining whether a Regulatory Material Adverse Effect would reasonably be expected to occur both the positive and negative effects of any actions, conduct, restrictions and conditions, including any sale, divestiture, licensing, lease, disposition or change or proposed change in rates, will be taken into account. Notwithstanding the foregoing, Seller shall not take, consent to or agree to take any action with respect to the Business or the Purchased Assets that would reasonably be expected to have a material adverse effect on the financial condition, properties, assets, liabilities (contingent or otherwise) business or results of operations of the Post-Sale Company (as defined in the Merger Agreement) and its Subsidiaries, without Parent’s written consent.

(f) Seller and Buyer will cooperate with each other and promptly prepare and file notifications with, and request Tax clearances from, state and local taxing authorities in jurisdictions in which a portion of the Purchase Price may be required to be withheld or in which Buyer would otherwise be liable for any Tax liabilities of Seller pursuant to such state and local Tax Law.

(g) Each of Buyer, Seller and Parent will keep the other apprised of the status of matters relating to completion of the transactions contemplated by this Agreement, the Merger Agreement and the Partnership Interests Purchase Agreement. Without limiting the foregoing, each of Buyer, Seller and Parent will promptly furnish the other with copies of any notice or other communication received by it or its Subsidiaries from any Person with respect to the transactions contemplated by this Agreement, the Merger Agreement or the Partnership Interests Purchase Agreement regarding (i) the occurrence or existence of (A) the breach in any material respect of a representation, warranty or covenant made by the other in this Agreement, or (B) any fact, circumstance or event that has had, or individually or in the aggregate would reasonably be expected to have a Material Adverse Effect; (ii) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated hereby; and (iii) (A) the commencement or, to a Party’s knowledge, threatened commencement of any material Claims against such Party, (B) the commencement of any material internal investigations or the receipt of any material and reasonably credible whistleblower complaints relating to a Party or any of its Subsidiaries, or (C) the entry of any material Order relating to a Party.

(h) Seller agrees that none of the information supplied or to be supplied by Seller or its Subsidiaries in writing specifically for Buyer’s use in preparing, or incorporation by reference, in any registration statement to be filed by Buyer in connection with obtaining Buyer’s financing will, at the time such registration statement is filed with the SEC, is amended or supplemented, or becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, not misleading.

(i) Buyer agrees that none of the information supplied or to be supplied by Buyer or its Subsidiaries in writing specifically for Seller’s and Parent’s use in preparing, or

1-LA/903877.26

incorporation by reference, in any registration statement to be filed by Seller and Parent in connection with the transactions contemplated by the Merger Agreement will, at the time such registration statement is filed with the SEC, is amended or supplemented, or becomes effective under the Securities Act, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, not misleading.

(j) Each of Seller, Parent and Buyer will, and will cause its Subsidiaries, including in the case of Parent, Seller’s successor, to cooperate with the others and use reasonable best efforts to take or cause to be taken all actions and do or cause to be done all things necessary, proper or advisable on its part to enable Buyer, Parent, Seller and Seller’s successor to perform their respective obligations under the Transition Services Agreement, including participation in the Transition Services Committee to be established pursuant to the Transition Services Agreement, and implementation of the Transition Plan in accordance therewith.

8.5.	Procedures with Respect to Certain Agreements and Other Assets.

(a) Seller has easements, real property license agreements (including railroad crossing rights), rights-of-way, and leases for rights-of-way, which relate solely to the Business and Purchased Assets (the “Easements”). At the Closing, Seller will convey and assign to Buyer, subject to the obtaining of any necessary consents, (i) by the Assignment of Easements, all Easements, and (ii) to the extent practicable, by separate, recordable Assignment of Easement as to all Easements in each separate County. Buyer and Seller agree that if Buyer and Seller determine that Seller’s Kansas electric utility operations “share” Easements with Seller’s gas utility operations in Kansas, Buyer and Seller will take all actions reasonably necessary (such as executing sub-easements or other documents) to ensure Buyer is permitted to use the same on a non-exclusive basis, as presently used by Seller with respect to its Kansas gas utility operations.

(b) To the extent that any of the Purchased Assets or Seller’s rights under any Business Agreement may not be assigned to Buyer without the consent of another Person which consent has not been obtained, this Agreement will not constitute an agreement to assign the same if an attempted assignment would constitute a breach thereof or be unlawful. Seller will use its reasonable best efforts (without being required to make any payment to any third party or incur any economic burden, except as may be specifically required under any Business Agreement in connection with the grant of such consent) to obtain any such required consent as promptly as possible. Buyer agrees to cooperate with Seller in its efforts to obtain any such consent (including the submission of such financial or other information concerning Buyer and the execution of any assumption agreements or similar documents reasonably requested by a third party) without being required to make any payment to any third party or to incur any economic burden (other than the assumption of Seller’s obligations under the applicable Business Agreement). Seller and Buyer agree that if any consent to an assignment of a Purchased Asset, including any Business Agreement, is not obtained or if any attempted assignment would be ineffective or would impair Buyer’s rights to such Purchased Assets or Buyer’s rights and obligations under the Business Agreement in question so that Buyer would not acquire the benefit of all such rights and obligations, at the Closing the Parties will, to the maximum extent permitted by Law and such Business Agreement, enter into such arrangements with each other as are reasonably necessary to effect the transfer or assignment of such

1-LA/903877.26

Purchased Asset or to provide Buyer with the benefits and obligations of such Business Agreement from and after the Closing.

(c) To the extent that any Business Agreement consisting of a futures contract, options contract, or other derivatives transaction (but not including contracts for physical delivery) (each, a “Financial Hedge”) is not assignable due to the rules and regulations of the Commodities Futures Trading Commission, the New York Mercantile Exchange or other futures or options exchange on which the Financial Hedge was entered into, or the relevant clearinghouse, Buyer and Seller agree that the Financial Hedge will be liquidated at or promptly after the Closing. Liquidation proceeds will be paid as follows: (i) in the event Seller’s aggregate ▇▇▇▇-to-market value of the Financial ▇▇▇▇▇▇ is positive, Seller will pay Buyer the ▇▇▇▇-to-market value of the Financial ▇▇▇▇▇▇; or (ii) in the event Seller’s aggregate ▇▇▇▇-to-market value of the Financial ▇▇▇▇▇▇ is negative, Buyer will pay Seller the ▇▇▇▇-to-market value of the Financial ▇▇▇▇▇▇. On or before the Closing, the Parties will agree on a specific procedure to liquidate the non-assignable Financial ▇▇▇▇▇▇, and any payment due as a result of such liquidation under this Section 8.5(c) will be made at or promptly after the Closing. Seller will calculate the ▇▇▇▇-to-market value of the Financial ▇▇▇▇▇▇ in accordance with its usual and customary practice.

(d) Buyer and Parent agree that the agreements, if any, described on Schedule 8.5(d) (the “Shared Agreements”), which will be attached to this Agreement prior to July 1, 2007 by the mutual agreement of Buyer and Parent, will be governed by this Section 8.5(d) and will not be Business Agreements for purposes of this Agreement. Seller’s rights and obligations under the Shared Agreements, to the extent such rights and obligations relate to the Business, are described on Schedule 8.5(d), and are referred to herein as the “Allocated Rights and Obligations.” Unless Parent elects for Seller or its successor to enter into Other Arrangements, Seller shall, or Parent shall cause Seller’s successor to, cooperate with Buyer and use their reasonable best efforts to enter into agreements (effective from and after the Closing Date) with the other party or parties to each Shared Agreement providing for (i) assignment to and assumption by Buyer, effective from and after the Closing, of the Allocated Rights and Obligations, and (ii) retention by Seller or its successor of all rights and obligations of Seller under the Shared Agreements other than the Allocated Rights and Obligations (such agreements set forth in (i) and (ii) being referred to as “Substitute Arrangements”); provided, that neither Seller or its successor nor Buyer will be obligated to enter into or agree to any such Substitute Arrangements unless such Substitute Arrangements have the effect of transferring to Buyer the Allocated Rights and Obligations (and reserving to Seller or its successor the rights and obligations which are not Allocated Rights and Obligations) on a fair and equitable basis, as determined in the reasonable discretion of Parent and Buyer. In connection with the foregoing, Parent, Seller and Buyer will, and Parent will cause Seller’s successor to, as reasonably requested, to submit such financial or other information concerning themselves or Seller, and to execute such assumption agreements or similar documents reasonably requested by a third party; provided that no Party will be, and Seller’s successor will not be, required to make any payment to any third party or to incur any economic burden (other than the assumption of the Allocated Rights and Obligations by Buyer, and the retention of the other rights and obligations under the Shared Agreements by Seller or its successor). In the event that (x) Buyer and Seller or its successor are unable to enter into Substitute Arrangements with respect to a Shared Agreement in accordance with the foregoing, or (y) Seller notifies Buyer that it elects not to pursue Substitute Arrangements with respect to such Shared Agreement, then in either case at or

1-LA/903877.26

promptly after the Closing Buyer and Seller, to the maximum extent permitted by Law and such Shared Agreement, will enter into such arrangements with each other as are necessary to provide Buyer with the benefits and obligations of the Allocated Rights and Obligations under such Shared Agreement, with Seller or its successor retaining the other benefits and obligations under such Shared Agreements from and after the Closing (the “Other Arrangements”).

(e) Seller from time to time provides collateral or other security to certain other Persons in connection with certain Business Agreements, Financial ▇▇▇▇▇▇ and Shared Agreements. Seller and Buyer agree to use their reasonable best efforts to cause such collateral or other security to be returned to Seller (including in the case of a letter of credit a return of the letter of credit to Seller), or released (in the case of other credit support previously provided by Seller) at or promptly after the Closing. In the event that such collateral or other security is not returned to Seller or otherwise released at or promptly after the Closing, Buyer will (i) pay to Seller, or its successor, an amount equal to any cash collateral posted by Seller; and (ii) in the case of a letter of credit provided in connection with a Business Agreement, replace such letter of credit as soon as practicable, or if such letter of credit is provided in connection with a Shared Agreement, provide to Seller, or its successor, a back-up letter of credit in the same amount and for a period expiring no earlier than ten (10) days following the expiration of the letter of credit previously provided by Seller. The provisions of this Section 8.5(e) will apply to collateral or other security provided in connection with Shared Agreements to the extent such collateral or other security is related to the Allocated Rights and Obligations under such Shared Agreements.

(f) In the event that any approval for the transfer of any of the Purchased Assets to Buyer is required from the Federal Communications Commission or any Franchise authority, and such approval is necessary to obtain in order to avoid violation of any Law, but is not a Required Regulatory Approval, the Parties agree that if such approval is not obtained prior to the Closing:

(i) they will each continue to use, and Parent and Seller will, and Parent will cause Seller’s successor to use, reasonable best efforts to obtain, and with respect to Parent, to cause Seller’s successor to obtain, such approvals as promptly as possible;

(ii) any of the Purchased Assets, the transfer of which to Buyer in the absence of such an approval would cause or lead to a violation of any Law (the “Contingent Purchased Assets”), shall not be transferred to Buyer at the Closing, but Seller will, or Parent will cause Seller’s successor to, transfer such assets immediately upon receipt of the requisite approvals, with the time between the Closing and the receipt of such approval being referred to as the “Interim Period”

(iii) during the Interim Period, Seller or its successor shall continue to have all title, rights, and obligations in the Contingent Purchased Assets to the extent necessary to avoid any violation of Law; and

(iv) Buyer will, and Seller will, or Parent will cause Seller’s successor to, enter into such arrangements with each other prior to Closing as are permissible under Law and reasonably necessary to provide Buyer with the benefits and obligations in

1-LA/903877.26

respect of the Contingent Purchased Assets from and after the Closing, and otherwise on terms and conditions reasonably acceptable to Buyer and Seller or its successor.

(g) Following the Closing, Buyer and Seller will, or Parent will cause Seller’s successor to, promptly remit to the other any payments Buyer or Seller or its successor receives that are in satisfaction of any rights or assets belonging to the other.

(h) With respect to the vehicles that are included in the Purchased Assets and that are subject to the Master Lease Agreement described in Schedule 5.8, Seller shall, upon written notice from Buyer, purchase such vehicles prior to the Closing and obtain the release of the liens on such vehicles as indicated in Schedule 5.8.

8.6. Public Statements. Each Party will consult with the other prior to issuing any press releases or otherwise making public announcements with respect to the transactions contemplated by this Agreement, except (i) as may be required by Law or by obligations pursuant to any listing agreement with or rules of any national securities exchange or any self-regulatory organization, and(ii) for any consultation that would not be reasonably practicable as a result of requirements of Law.

8.7.	Tax Matters.

(a) All transfer, documentary, stamp, registration, sales and use Taxes, including real property conveyance Taxes (“Transfer Taxes”), incurred in connection with this Agreement and the transactions contemplated hereby shall be shared equally between Seller or its successor, on the one hand, and Buyer, on the other hand. To the extent required by applicable Law, Seller shall, or Parent shall cause Seller’s successor to, at its own expense, file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes, and, if required by applicable Law, Buyer shall join in the execution of any such Tax Returns or other documentation. Buyer shall remit to Seller, within 20 days after receipt of notice as to the amount of such Transfer Taxes that are payable on or after the Closing or have been paid, 50 percent of the total amount of such Transfer Taxes. In the event there is an additional assessment of such Transfer Taxes or an amount of such Transfer Taxes is refunded, (i) Buyer and Seller shall share equally the amount of any such additional assessment, with the Party that is not required to pay such Transfer Tax under applicable Law remitting to the other 50 percent of such additional assessment within 20 days after receiving notice of a final determination, and (ii) Buyer and Seller shall share equally the amount of any such refund, with the Party receiving such refund paying 50 percent of such refund to the other within 20 days after receiving such refund (or claiming an offset against Taxes relating to such refund).

(b) Buyer will be responsible for the preparation and timely filing of all Tax Returns associated with the Business, the Purchased Assets and the Business Employees for (i) in the case of property Taxes and payroll Taxes, all periods that begin before and end after the Closing Date (the “Straddle Period Taxes”), and (ii) in the case of all Taxes, all periods that begin after the Closing Date, and for the timely payment of all Taxes described in clauses (i) and (ii) of this Section 8.7(b).

(c) Any Tax Return that reflects Transfer Taxes or that reflects Taxes to be prorated in accordance with Section 3.4 will be subject to the approval of the Party not preparing

1-LA/903877.26

such return, which approval will not be unreasonably withheld or delayed. Each Party will make any such Tax Return prepared by it available for the other Party’s review and approval no later than twenty (20) Business Days prior to the due date for filing such Tax Return.

(d) Buyer, Parent and Seller will, and Parent will cause Seller’s successor to, provide one another with such assistance as may reasonably be requested by such other Persons in connection with the preparation of any Tax Return, any audit or other examination by any Governmental Entity, or any judicial or administrative proceedings relating to liability for Taxes, and each of Buyer, Parent and Seller will, and Parent will cause Seller’s successor to, retain and provide the other with any records or information which may be relevant to such return, audit or examination or proceedings. Any information obtained pursuant to this Section 8.7(d) or pursuant to any other Section hereof providing for the sharing of information in connection with the preparation of, or the review of, any Tax Return or other schedule relating to Taxes will be kept confidential by the Parties hereto in accordance with Section 8.2(b).

8.8.	Employees and Employee Benefits.

(a) No later than twenty (20) Business Days prior to the Closing Date, Buyer will give Qualifying Offers of employment commencing as of the Closing Date to all Business Employees, including any such employees who are on a leave of absence under the Family and Medical Leave Act, the Uniformed Services Employment and Reemployment Rights Act or other applicable Law, or authorized under Seller’s established leave policy, including short-term or long-term disability. For this purpose, a “Qualifying Offer” means employment at a level of base pay at least equal to the Business Employee’s base pay in effect immediately prior to the Closing Date, and with a primary work location no more than fifty (50) miles from the Business Employee’s primary work location immediately prior to the Closing Date; provided, however, that with respect to any Business Employee who is covered by a Collective Bargaining Agreement or Successor Collective Bargaining Agreement, the Qualifying Offer shall be on terms and conditions set forth in the Collective Bargaining Agreement, Successor Collective Bargaining Agreement or, if applicable, a new collective bargaining agreement negotiated by Buyer covering such employee. Each Business Employee who becomes employed by Buyer pursuant to this Section 8.8(a) is referred to herein as a “Transferred Employee.” Each Transferred Employee who is covered by a Collective Bargaining Agreement or a Successor Collective Bargaining Agreement shall be referred to herein as a “CB Transferred Employee,” and each Transferred Employee who is not covered by a Collective Bargaining Agreement or a Successor Collective Bargaining Agreement shall be referred to herein as a “Non-CB Transferred Employee.”

(b) All offers of employment made by Buyer pursuant to Section 8.8(a) will be made in accordance with all applicable Laws, will be conditioned only on the occurrence of the Closing, and will remain open until the Closing Date. Any such offer which is accepted before it expires will thereafter be irrevocable, except for good cause. Following acceptance of such offers, Buyer will provide written notice thereof to Seller and Seller will, or Parent will cause Seller’s successor to, provide Buyer with access to the Transferred Employee Records consistent with applicable Law. Buyer will be responsible for all liabilities and obligations for and with respect to any Business Employees who do not become Transferred Employees including (i) pursuant to Exhibit 8.8(d)(ii)(C), (ii) due to retirement by such employee after the date hereof and prior to Closing, (iii) severance benefits which become payable to such Business

1-LA/903877.26

Employee upon any termination of such Business Employee’s employment on or following the Closing Date, and (iv) the benefits described in Section 8.8(d)(ii)(D), but not including liabilities and obligations with respect to insured welfare benefits provided to such Business Employee for periods prior to the Closing Date. Without limiting the obligations of Buyer hereunder, the employment of each Business Employee who does not become a Transferred Employee as of the Closing shall be terminated immediately following the Closing by Seller or the applicable Affiliate of Seller.

(c) From and after the Closing Date, Buyer will recognize the union locals that are the counterparties to Seller under the Collective Bargaining Agreements or any Successor Collective Bargaining Agreements entered into in compliance with Section 8.1(a) (the “Locals”) as the exclusive bargaining representatives of the bargaining units that include CB Transferred Employees. No later than twenty (20) Business Days prior to the Closing Date, Buyer will negotiate and reach agreement with each Local on the terms and conditions of a new collective bargaining agreement to be effective from and after the Closing Date with respect to the applicable bargaining unit represented by such Local (each such agreement being referred to as a “New CBA”). Should Buyer fail to successfully negotiate a New CBA with a Local at least twenty (20) Business Days prior to the Closing Date, then at the Closing, Buyer will assume the existing Collective Bargaining Agreement or, as applicable, Successor Collective Bargaining Agreement entered into in compliance with Section 8.1(a), to the extent applicable to the bargaining unit represented by such Local and to the extent consistent with applicable Law; provided that Buyer shall not assume any of the Benefit Plans (but may receive assets to be transferred from such plans pursuant to Exhibit 8.8(d)(ii)(C)), and Buyer will instead provide benefits of the type and amount described in the existing Collective Bargaining Agreements or Successor Collective Bargaining Agreements entered into in compliance with Section 8.1(a), as applicable, through Buyer’s own benefit plans and arrangements. Buyer agrees that (i) upon request by Seller, Buyer will notify Seller of the status of negotiations with each Local, and (ii) no later than nineteen (19) Business Days prior to the Closing Date, Buyer will notify Seller whether a New CBA has been successfully negotiated with such Local.

(d) The following will be applicable with respect to the Transferred Employees, Business Employees, Current Retirees, and Other Plan Participants as appropriate. For all purposes of this Section 8.8, determinations as to whether any individuals are “similarly situated” shall be made by Buyer in its reasonable discretion.

(i) From and after the Closing, the Transferred Employees will accrue no additional benefits under any Benefit Plan or any other employee benefit plan, policy, program, or arrangement of Seller, Parent or their respective Affiliates.

(ii) As of the Closing, with respect to the CB Transferred Employees, Buyer will provide benefits of the type and amount described in the relevant collective bargaining agreements through Buyer’s own benefit plans and arrangements. As of the Closing and extending through December 31 of the calendar year following the calendar year in which the Closing occurs, Buyer will cause the Non-CB Transferred Employees to be covered by Buyer benefit plans that provide compensation and employee benefits (excluding (i) equity or equity based compensation, and (ii) change in control, severance or retention payments) that are no less favorable in the aggregate than provided to the Non-CB Transferred Employees immediately before the Closing ; provided, that in

1-LA/903877.26

determining the timing, amount and terms and conditions of equity compensation and other incentive awards to be granted to Non-CB Transferred Employees, Buyer will treat in a substantially similar manner Non-CB Transferred Employees and similarly situated other employees of Buyer (including by reason of job duties and years of service). The commitments under this Section 8.8(d)(ii) require the following with respect to the Non-CB Transferred Employees and, to the extent not addressed in the relevant collective bargaining agreement, the CB Transferred Employees:

(A) With respect to welfare benefit plans, Buyer agrees to waive or to cause the waiver of all restrictions, limitations or exclusionary periods as to pre-existing conditions, actively-at-work exclusions, waiting periods and proof of insurability requirements (to the extent allowable under Buyer’s welfare benefit plans and insurance policies) for the Transferred Employees to the same extent waived or satisfied under the corresponding Benefit Plans. With respect to the calendar year in which the Closing Date occurs, all eligible expenses incurred by any such employees or any eligible dependent thereof, including any alternate recipient pursuant to qualified medical child support orders, in the portion of the calendar year preceding the Closing Date that were qualified to be taken into account for purposes of satisfying any deductible, co-insurance or out-of-pocket limit under any Seller Benefit Plan will be taken into account for purposes of satisfying any deductible, co-insurance or out-of-pocket limit under similar plans of Buyer for such calendar year. As soon as practicable, but in no event later than sixty (60) days after the Closing Date, Seller will, or Parent will cause Seller’s successor to, provide Buyer with all relevant information necessary or reasonably requested by Buyer for purposes of administering this provision, consistent with applicable Law.

(B) With respect to service and seniority, Buyer will recognize the service and seniority of each of the Transferred Employees recognized by Seller for all material purposes, including the determination of eligibility and vesting, the extent of service or seniority-related welfare benefits, and eligibility for and level of retiree health benefits, but in any event not for purposes of determining the accrual of pension benefits and levels of pension or other retirement income benefits.

(D) Buyer will assume all liabilities, obligations, and responsibilities with respect to providing post-retirement health and life insurance benefits arising under or pursuant to existing plans and agreements of Seller (“Post-Retirement Welfare Benefits”) to (i) the persons listed on Schedule 8.8(d)(ii)(D) and any Business Employee who retires between the date hereof and the Closing Date (such listed persons and such Business Employees, the “Current Retirees”), and their spouses and eligible dependents, and (ii) the Business Employees (together with the Current Retirees, the “Covered Individuals”) and their spouses and eligible dependents. From and after the Closing, Buyer will continue to provide to the Covered Individuals Post-Retirement Welfare Benefits that, in material respects, are comparable to in the aggregate those Post-Retirement Welfare Benefits provided to such Covered Individuals immediately prior to the Closing Date, under cost-sharing structures that either are at least as favorable as the cost-sharing structures in effect for and available to the Covered Individuals immediately

1-LA/903877.26

prior to the Closing Date (as adjusted for inflation); provided that if Buyer reduces or eliminates any Post-Retirement Welfare Benefits provided to Covered Individuals from such benefits that are available to such individuals under the terms and conditions of the existing plans and agreements of Seller applicable to such individuals as in effect on the date hereof, any liabilities arising in connection with such reduction or elimination shall be deemed an Assumed Obligation and Buyer will be responsible therefor.

(E) With respect to the Aquila, Inc. Retirement Investment Plan (the “Savings Plan”), Seller will vest Transferred Employees in their Savings Plan account balances as of the Closing Date. Buyer will take all actions necessary to establish or designate a defined contribution plan and trust intended to qualify under Section 401(a) and Section 501(a) of the Code in which Transferred Employees are eligible to participate (x) to recognize the service that the Transferred Employees had in the Savings Plan for purposes of determining such Transferred Employees’ eligibility to participate, vesting, attainment of retirement dates, contribution levels, and, if applicable, eligibility for optional forms of benefit payments, and (y) to accept direct rollovers of Transferred Employees’ account balances in the Savings Plan, including transfers of loan balances and related promissory notes, provided that such loans would not be treated as taxable distributions at any time prior to such transfer.

(F) Within sixty (60) days after the Closing Date, Seller will, or Parent will cause Seller’s successor to, transfer to a flexible spending plan maintained by Buyer any balances standing to the credit of Transferred Employees under Seller’s flexible spending plan as of the day immediately preceding the Closing Date, net of any negative balances in the applicable accounts at such time. As soon as practicable after the Closing Date, Seller will, or Parent will cause Seller’s successor to, provide to Buyer a list of those Transferred Employees that have participated in the health or dependent care reimbursement accounts of Seller, together with (x) their elections made prior to the Closing Date with respect to such account and (y) balances standing to their credit as of the day immediately preceding the Closing Date. As of the transfer described in the first sentence hereof, the flexible spending plan maintained by Buyer shall assume the rights and obligations of Seller’s flexible spending plan with respect to the Transferred Employees for the remainder of the year in which such transfer occurs. For the avoidance of doubt, this paragraph shall not be construed to require a transfer with respect to any Transferred Employee of an amount in excess of such employee’s unreimbursed contributions to the flexible spending plan as of the date of transfer.

(iii) With respect to severance benefits, Buyer will provide to any Non-CB Transferred Employee who is terminated by Buyer (other than for cause) prior to the date which is one (1) year following the Closing Date, severance benefits comparable to those provided by Seller under Seller’s severance plans and policies (other than any plans or policies with respect to stock options or other types of equity compensation) in effect immediately prior to the Closing Date. Any employee who is provided severance benefits under this Section 8.8(d)(iii) may be required to execute a release of claims against Buyer, Seller and their respective Affiliates and successors, in such form as Buyer reasonably prescribes, as a condition for the receipt of such benefits.

1-LA/903877.26

(iv) Parent will, or will cause Seller or its successor to, provide COBRA Continuation Coverage to any current and former Business Employees, or to any qualified beneficiaries of such Business Employees, who become or became entitled to COBRA Continuation Coverage on or before the Closing, including those for whom the Closing occurs during their COBRA election period. Buyer will be responsible for extending and continuing to extend COBRA Continuation Coverage to all Transferred Employees (and their qualified beneficiaries) who incur a COBRA qualifying event and thus become entitled to such COBRA Continuation Coverage following the Closing.

(v) Without limiting the obligations of the Parties under Sections 8.8(d)(ii)(C) and 8.8(d)(ii)(D), Seller or its Affiliates will pay or cause to be paid to all Transferred Employees, all compensation (including any accrued vacation carried over to the calendar year of the Closing from a previous calendar year), workers’ compensation or other employment benefits to which they are entitled or that have accrued under the terms of the applicable compensation or Seller Benefit Plans or programs with respect to employment or events occurring prior to the Closing Date; provided that if any of the CB Transferred Employees elect to retain or carryover accrued and unused vacation days rather than receive such payments, Seller or its Affiliates will pay or cause to be paid to Buyer an amount equal to the aggregate amount that would otherwise have been paid to such CB Transferred Employees with respect to such vacation days, and Buyer will honor all such accrued and unused vacation days of such CB Transferred Employees as of the Closing. Buyer will pay to each Transferred Employee all unpaid salary or other compensation or employment benefits (but not including any compensation attributable to stock options or other types of equity compensation granted by Seller) which accrue to such employee from and after the Closing Date, at such times as provided under the terms of the applicable compensation or benefit programs.

(vi) Without limiting the obligations of the Parties under Sections 8.8(d)(ii)(C) and 8.8(d)(ii)(D), Business Employees who on the Closing Date are not actively at work due to a leave of absence covered by the Family and Medical Leave Act, the Uniformed Service Employment and Reemployment Rights Act or other applicable Law, or other authorized leave of absence under Seller’s established leave policy, including short-term or long-term disability, will be provided by Buyer with benefits and compensation during such leave that is substantially similar to the benefits and compensation provided to such employees by Seller prior to the Closing Date, and will be treated as Transferred Employees on the date that they are able to return to work (provided that such return to work occurs within the authorized period of their leaves following the Closing Date) and are able to perform the essential functions of their jobs with or without reasonable accommodation. Seller shall provide Buyer with a list of such individuals as of the Closing Date with the scheduled dates for expiration of their leaves.

(vii) Buyer will assume Seller’s obligations as of the Closing Date to pay nonqualified deferred compensation to the applicable Business Employees and former Business Employees.

(e) On or before the Closing Date, Seller shall provide Buyer a list of the names and sites of employment of any and all Business Employees who have experienced, or

1-LA/903877.26

will experience, an employment loss or layoff as defined by WARN Act or any similar applicable state or local Law requiring notice to employees in the event of a closing or layoff within ninety (90) days prior to the Closing Date. Seller shall update this list up to and including the Closing Date. For a period of ninety (90) days after the Closing Date, Buyer shall not engage in any conduct which would result in an employment loss or layoff for a sufficient number of employees of Buyer which, if aggregated with any such conduct on the part of Seller prior to the Closing Date, would trigger the WARN Act or any similar applicable Law. Without limiting the foregoing, Buyer will be responsible, with respect to the Business, for performing and discharging all requirements under the WARN Act and under applicable state and local laws and regulations for the notification to Transferred Employees of any “employment loss” within the meaning of the WARN Act which occurs at or following the Closing Date.

(f) From and after the Closing Date, with respect to worker’s compensation, Buyer shall assume, discharge, pay and be solely liable for all Losses in respect of any Claims pending as of or commenced after the Closing Date resulting from actual or alleged harm or injury to any Business Employee regardless of when the incident or accident giving rise to such liability occurred or occurs. Buyer shall make all necessary arrangements to assume all such worker’s compensation claim files, whether opened or closed, as of the Closing Date, and will make the necessary arrangements for assuming the continued management of such liabilities.

(g) From and after the Closing Date, except to the extent any such Losses are covered under Seller’s or an Affiliates’ third party insurance plans or policies, reinsurance policies or arrangements, or trusts or other funding vehicles, Buyer shall assume, discharge, pay and be solely liable for health, accidental death and dismemberment, short term disability or life insurance coverage and any medical or dental benefits to the Business Employees and their eligible dependents.

(h) Buyer agrees that from and after the Closing Date, if a Business Employee commences an action, suit or proceeding relating to an employment-related claim (but excluding, in any event the ERISA Case), any resulting Liability shall be the responsibility of Buyer. Parent shall reasonably cooperate with Buyer in the defense of any such claim to the extent that the applicable actions or events transpired preceding the Closing Date.

(i) For purposes of Sections 8.8(f), 8.8(g) and 8.8(h), the term “Business Employees” shall also include any individuals who (A) were employed principally for the Business at the time the incident or circumstances giving rise to such suit, claim, action, proceeding or Loss occurred, and (B) who are not employed by Seller either as of the date hereof or as of the Closing Date.

(j) No provision in this Agreement shall modify or amend any other agreement, plan, program or document, including any of Buyer’s benefit plans or arrangements, unless this Agreement explicitly states that the provision “amends” that other agreement, plan, program or document. This shall not prevent the parties entitled to enforce this Agreement from enforcing any provision in this Agreement, but no other party shall be entitled to enforce any provision in this Agreement on the grounds that it is an amendment to another agreement, plan, program or document, unless a provision is explicitly designated as such in this Agreement, and the person is otherwise entitled to enforce such other agreement, plan, program or document. If a party not entitled to enforce this Agreement brings a lawsuit or other action to enforce any

1-LA/903877.26

provision in this Agreement as an amendment to another agreement, plan, program or document, and such provision is construed to be such an amendment despite not being explicitly designated as an amendment in this Agreement, such provision shall lapse retroactively, thereby precluding it from having any amendatory effect. The provisions of this Section 8.8 are not, and will not be construed as being, for the benefit of any Person other than the Parties, and are not enforceable by any Persons (including Transferred Employees, Current Retirees, and Other Plan Participants) other than such Parties.

(k) Following the Closing, if Buyer or Seller or its successor identifies any individual that was incorrectly classified by Seller (including employees not listed in Schedule 1.1-B) with respect to whether such individual was a Business Employee, a former employee of the Natural Gas Businesses or a Current Retiree, as applicable, Buyer and Seller, or Parent shall cause Seller’s successor to, each agree to notify the other Party and, acting in good faith, to take, or cause to be taken, all action, and to do, or cause to be done, all things reasonably necessary, proper or advisable to cause such individual to be appropriately classified for purposes of this Agreement, and to allocate the liabilities and obligations related to such re-classified individual in accordance with the terms hereof.

8.9.	Eminent Domain; Casualty Loss.

(a) If, before the Closing Date, any of the Purchased Assets are taken by eminent domain or condemnation, or are the subject of a pending or (to Seller’s Knowledge) contemplated taking which has not been consummated, Seller will (i) notify Buyer promptly in writing of such fact, and (ii) at the Closing assign, or Seller shall, or Parent shall cause Seller’s successor to, assign to Buyer all of Seller’s right, title, and interest in and to any proceeds or payments received, or to be received, in compensation for such taking.

(b) If, before the Closing Date, all or any material portion of the Purchased Assets are damaged or destroyed by fire or other casualty, Seller will notify Buyer promptly in writing of such fact and, at the Closing assign, or Seller shall, or Parent shall cause Seller’s successor to, assign all of Seller’s right, title, and interest in and to any insurance recoveries received, or to be received, in compensation for such damage or destruction less any such amounts received, or to be received, to reimburse Seller for expenditures incurred by Seller to repair or replace such Purchased Assets.

(c) Seller and Buyer will use their reasonable best efforts (without being required to make payment to any third party or to incur any economic burden) to obtain from each holder of any Preferential Purchase Right a written waiver of such Preferential Purchase Right if required with respect to the transactions contemplated by this Agreement (an “Applicable Preferential Purchase Right”). If the Parties cannot obtain a waiver of an Applicable Preferential Purchase Right, the Parties will cooperate, using reasonable best efforts, to provide for compliance with the terms of such Applicable Preferential Purchase Right. In the event that any Purchased Asset remains subject to such Applicable Preferential Purchase Right as of the Closing, in lieu of any adjustment to the Purchase Price, Seller will, or Parent will cause Seller’s successor to, at the Closing assign to Buyer, as a Purchased Asset, all of Seller’s right, title, and interest in and to all rights of Seller with respect to such Applicable Preferential Purchase Right, including proceeds received or to be received in respect to such Applicable Preferential Purchase Right, and will assign to Buyer and Buyer will assume, as Assumed Obligations, all obligations

1-LA/903877.26

of Seller with respect to such Applicable Preferential Purchase Right. If any third party holding a Preferential Purchase Right exercises such right prior to the Closing, Seller shall promptly give Buyer written notice of such exercise. Buyer and Seller hereby expressly acknowledge and agree that nothing in this Agreement constitutes an offer or agreement to sell, transfer, dispose of, purchase, assume, or acquire any asset subject to a Preferential Purchase Right except upon the Closing following the satisfaction of all conditions to Closing specified in this Agreement. Neither this Agreement nor anything herein or in connection herewith shall be deemed to obligate Seller to sell, transfer, assign or otherwise dispose of any Purchased Asset or Assumed Obligation, to Buyer or any other Person, except upon the Closing following the satisfaction or waiver of all conditions to Closing specified in this Agreement.

(d) A condemnation or taking of, casualty or exercise of a Preferential Purchase Right set forth in Schedule 5.8 with respect to, any Purchased Asset, and any effects thereof (including any resulting termination of any Franchise or other agreement principally related to such Purchased Asset), may be taken into account in determining whether a Material Adverse Effect has occurred; provided that to the extent Buyer is assigned the rights, title and interest to any payments or proceeds received by Seller with respect to any such condemnation or taking, casualty or exercise of a Preferential Purchase Right, such payments or proceeds may be considered in determining whether any Material Adverse Effect has occurred; provided further that assignment of such proceeds or payments to Buyer shall not necessarily mean a Material Adverse Effect did not occur.

8.10. Transitional Use of Signage and Other Materials Incorporating Seller’s Name or other Logos. Parent acknowledges that it will have no ongoing claim or rights in or to the Seller Marks. Within one hundred eighty (180) days following the Closing Date, Parent will remove or cause the removal of the Seller Marks from all signage or other items relating to or used in connection with the Excluded Assets and, thereafter, Parent will not use or permit the use of any Seller Marks.

8.11. Litigation Support. In the event and for so long as Buyer, Parent or Seller or its successor is actively contesting or defending against any third-party Claim in connection with (i) any transaction contemplated under this Agreement or (ii) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act, or transaction on or prior to the Closing Date involving Seller, Buyer, Parent and Seller will, and Parent will cause Seller’s successor to, cooperate with the contesting or defending Person and its counsel in the contest or defense, make reasonably available its personnel, and provide such testimony and access to its books and records as is reasonably necessary in connection with the contest or defense, all at the sole cost and expense of the contesting or defending Person.

8.12.

Audit Assistance.

(a) If, (i) during or for the period beginning on the date hereof and ending on the Closing Date, Buyer is, in connection with any annual or quarterly report filed with the SEC, required by the SEC to file audited or reviewed financial statements of the Business in respect of any period occurring prior the Closing Date, or (ii) during or for the period beginning on the date hereof and ending on the last day of the calendar year of the Closing, Buyer is, in connection with a registration statement or other voluntary filing to be filed by Buyer with the SEC, required by the SEC to file audited or reviewed financial statements of the Business in respect of any

1-LA/903877.26

period occurring prior the Closing Date, then in each case at Buyer’s request, as applicable, Seller will, or Parent will cause Seller’s successor to, use its reasonable best efforts to cause Seller’s auditor to, at Buyer’s sole cost and expense, (a) cooperate with and provide Buyer access to such information, books and records as necessary for Buyer to prepare audited and interim or reviewed financial statements of the Business, and (b) agree to provide to Buyer an audit or review of the financial statements of the Business, for the periods necessary to satisfy the SEC requirements (and any consents, if any, to use such audited or reviewed financial statements in Buyer’s SEC filings). Further, Seller will use reasonable best efforts to assist Buyer in preparing pro forma financial information that in Buyer’s reasonable judgment may be required to be included in any such filing or prospectus, offering memorandum or other document or materials that may be prepared in connection with the Buyer Financing or otherwise on or prior to the Closing, and, whether or not Seller’s auditor is retained by Buyer to conduct an audit or review of the Business, Seller will, or Parent will cause Seller’s successor to (x) use its reasonable best efforts to cause Seller’s auditor to, at Buyer’s sole cost and expense, make available to Buyer and its auditors the work papers and other documents and records reasonably requested by Buyer that were created prior to the Closing and relate principally to the Business, and (y) cooperate with Buyer, at Buyer’s sole cost and expense, in obtaining an audit or review of the Business, in each case, to the extent required by the SEC.

(b) Seller acknowledges and agrees that any audited and interim or reviewed financial statements and related information prepared in accordance with this Section 8.12 will not be deemed Confidential Information for purposes of this Agreement.

8.13. Notification of Customers. As soon as practicable following the Closing, Seller will, or Parent will cause Seller’s successor to, cooperate with Buyer to cause to be sent to customers of the Business a notice of the transfer of the customers from Seller to Buyer (the “Customer Notification”). The Customer Notification will contain such information as is required by Law and approved by Buyer and Seller, which approval will not be unreasonably withheld or delayed.

8.14. Financing. Buyer will use reasonable best efforts to take or to cause to be taken, all actions, and to do or cause to be done, all things necessary, proper or advisable to close the Buyer Financing on the terms and conditions described in the Buyer Financing Commitments by the date upon which the Closing Date is contemplated to occur in accordance with Section 4.1 (provided and to the extent that Buyer has not otherwise obtained funds sufficient to pay the Purchase Price through other sources of funds and provided that Buyer may replace or amend the Buyer Financing Commitments after consultation with Parent and Seller but only if the terms of such replacement or amended Buyer Financing Commitments, including with respect to conditionality, would not adversely impact Buyer’s ability to consummate the transactions contemplated by this Agreement or the Partnership Interests Purchase Agreement, or otherwise prevent, impact or delay the consummation of the transactions contemplated by this Agreement or the Partnership Interests Purchase Agreement), including paying the commitment fees arising under the Buyer Financing Commitments as and when such fees become due and payable during the period beginning on the date hereof and ending on the Closing Date, and using reasonable best efforts to (i) negotiate definitive agreements with respect thereto on the terms and conditions contained therein and (ii) to satisfy on a timely basis all conditions applicable to obtain the Buyer Financing. In the event any portion of the Buyer Financing becomes unavailable on the terms and conditions contemplated in the Buyer Financing Commitments and Buyer has not otherwise

1-LA/903877.26

obtained other sources of funds, Buyer will use reasonable best efforts to obtain alternative financing from alternative sources by the date upon which the Closing Date is contemplated to occur in accordance with Section 4.1. Buyer will give prompt notice to Seller and Parent of any material breach of the Buyer Financing Commitments of which Buyer becomes aware or any termination of the Buyer Financing Commitments or any Buyer Financing. Buyer will keep Seller and Parent informed on a regularly current basis in reasonable detail of the status of the Buyer Financing.

8.15. Document Delivery. The Parties will work cooperatively to make available to Buyer prior to the Closing such Documents as are reasonably necessary to transition the control and operation of the Business to Buyer at the Closing with minimal interruptions or disruptions in the conduct of the Business. At or within a reasonably practicable period of time after the Closing Date, Seller will, or Parent will cause Seller’s successor to, deliver to Buyer, at such location mutually agreed upon by Buyer and Seller or its successor, any remaining Documents. At Buyer’s reasonable request, Seller will, or Parent will cause Seller’s successor to, use reasonable best efforts to make available in an electronic format compatible with Buyer’s electronic systems any Documents and other books and records relating to the Purchased Assets which are maintained by Seller in electronic form.

8.16. Surveys’ Title Insurance, Estoppel Certificates, and Non-Disturbance Agreements. At Buyer’s option and at Buyer’s sole cost and expense, Buyer may obtain (i) surveys desired by Buyer in respect of the Real Property, in form and substance reasonably satisfactory to Buyer; (ii) title insurance policies in current ALTA Form or equivalent covering the Real Property, insuring title to the applicable Real Property as vested in Buyer, and in form, substance, and amounts reasonably satisfactory to Buyer, and without limiting the generality of the foregoing, with all requirements satisfied or waived, with all exceptions deleted, and with all endorsement thereto to the extent desired by Buyer; and (iii) all estoppel certificates and non-disturbance agreements desired by Buyer in respect of any real property leases included in the Purchased Assets, in form and substance reasonably satisfactory to Buyer and to the parties providing such certificates and agreements. Seller agrees, and Parent agrees to cause Seller’s successor, to cooperate as reasonably requested by Buyer (at Buyer’s expense) in its efforts to obtain such items, provided that (y) none of Seller, Parent, Seller or Seller’s successor shall be required to make any payment to any third party or incur any economic burden in connection therewith, and (z) Buyer’s obtaining any such items shall not be a requirement of or a condition to the Closing. In addition, with respect to Seller’s and Seller’s successor’s cooperation with Buyer’s reasonable requests to obtain title insurance under clause (ii) above, neither Seller nor Seller’s successor, except to the extent required to satisfy the Closing condition set forth in Section 9.2(f), and except for such actions as may be necessary to enable Buyer’s title insurance company to insure title to the applicable Real Property as vested in Buyer, shall be required to cure any purported defects, cause any exceptions to be deleted, or provide any affidavits, indemnities, or representations or warranties to any title company issuing such title insurance.

8.17.

Post-Closing Release of Encumbrances and Transfer of Purchased Assets.

(a) Notwithstanding anything to the contrary herein, if any Non-Permitted Encumbrances on the Business or the Purchased Assets are not released on or before the Closing, and such Non-Permitted Encumbrances secure or are created by or in respect of the Excluded Liabilities, or are for material delinquent Taxes or material delinquent assessments, Seller shall,

1-LA/903877.26

and Parent shall cause Seller’s successor to, promptly make such payments and take such actions as necessary to obtain the release of such Non-Permitted Encumbrances after the Closing.

(b) Notwithstanding anything to the contrary herein, if Seller fails to deliver any deeds of conveyance or assignments or other instruments, certificates or documents as necessary to transfer any of the Purchased Assets to Buyer at the Closing, Seller shall, and Parent shall cause Seller’s successor to, promptly execute and deliver such deeds of conveyance, assignments or other instruments, certificates or documents and take such actions as necessary to transfer such Purchased Assets to Buyer as soon as practicable after the Closing.

8.18. Shared Code Licenses. Buyer hereby grants to Parent a worldwide, non-exclusive, royalty-free, fully paid-up, sublicensable, transferable license to use, reproduce, make derivative works of, distribute, display and perform the Shared Code that is included in the Purchased Assets. Parent hereby grants to Buyer a worldwide, non-exclusive, royalty-free, fully paid-up, sublicensable, transferable license to use, reproduce, make derivative works of, distribute, display and perform the Shared Code that is included in the Excluded Assets. Except as set forth in the Transition Services Agreement, neither Buyer nor Parent shall have any obligation to support, maintain, provide updates or upgrades for, or otherwise provide any assistance to the other in connection with, the Shared Code. The foregoing licenses shall be binding on the respective successors and assigns of Buyer and Parent.

(b) This Agreement may be terminated by Seller or Buyer if the Closing has not occurred on or before the first anniversary of the date of this Agreement (the “Termination Date”); provided that, if Buyer or Seller determines that additional time is necessary to obtain any of the Required Regulatory Approvals, the Material Company Regulatory Consents or the Material Parent Regulatory Consents (each as defined in the Merger Agreement), or the “Required Regulatory Approvals” as defined in the Partnership Interests Purchase Agreement, or if all of the conditions to Parent’s obligations to consummate the Merger shall have been satisfied or shall be then capable of being satisfied and this Agreement fails to be consummated by reason of a breach by Parent of its obligation to be in a position to consummate the Merger after the Closing, the Termination Date may be extended by Buyer or Seller from time to time by written notice to the other Party and to Parent up to a date not beyond eighteen (18) months after the date of this Agreement, any of which dates shall thereafter be deemed to be the Termination Date; provided further that the right to terminate this Agreement under this Section 10.1(b) will not be available to a Party that has breached in any material respect its obligations under this Agreement in any manner that will have proximately contributed to the failure of the Closing to occur on or before the Termination Date.

representation or warranty of Buyer shall have become untrue after the date of this Agreement, so that Sections 9.3(a) and 9.3(b) would not be satisfied and this breach or failure to be true is not curable, or if curable, is not curable by the Termination Date (as the same may be extended).

(g) This Agreement may be terminated by Buyer or Seller upon or following the termination of the Merger Agreement in accordance with its terms.

10.2. Procedure and Effect of Termination. In the event of termination of this Agreement pursuant to Section 10.1, written notice thereof will forthwith be given by the terminating Party to the other Parties and this Agreement (other than as set forth in this Section 10.2, Section 10.4 and Section 11.1) will terminate and become void and of no effect, and the transactions contemplated hereby will be abandoned without further action by any Party, whereupon the liabilities of the Parties hereunder (and of any of their respective Representatives) will terminate, except as otherwise expressly provided in this Agreement; provided, that such termination will not relieve any Party from any liability for damages to any other Party resulting from any prior breach of this Agreement, the Partnership Interests Purchase Agreement or the Merger Agreement which is (i) material, and (ii) willful or knowing. If this Agreement is terminated pursuant to Section 10.1(e) or Section 10.1(g) upon or following termination of the Merger Agreement under circumstances where Seller is required to pay Parent the Company Termination Fee (as defined in the Merger Agreement) pursuant to the provisions of Section 9.5(b) of the Merger Agreement, Seller will, following such termination and at the time required under Section 9.5(b) of the Merger Agreement, pay into a joint bank account in the names of Buyer and Parent the termination fee required to be paid pursuant to the terms of the Merger Agreement, by wire transfer of same day funds. If this Agreement is terminated pursuant to Section 10.1(g) upon or following termination of the Merger Agreement under circumstances where Parent is required to pay Seller the Parent Termination Fee (as defined in the Merger Agreement) pursuant to the provisions of Section 9.5(c) of the Merger Agreement, Parent will, following such termination and at the time required for payment of the Parent Termination Fee (as defined in the Merger Agreement), pay Buyer the Termination Fee, which shall be in an amount (subject to the limitations thereon as set forth in the definition of Termination Fee set forth herein) reasonably agreed upon by Buyer and Parent. Seller and Parent acknowledge that the agreements contained in this Section 10.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, Buyer would not enter into this Agreement; accordingly, if Seller or Parent fails to pay promptly the amount due pursuant to this Section 10.2, and, in order to obtain such payment, Buyer commences a suit which results in a judgment against Seller or Parent, as the case may be, for the fee to be paid by such Party as set forth in this Section 10.2, Seller or Parent, as applicable, will pay to Buyer its costs and expenses (including attorneys’ fees) in connection with this suit, together with interest on the amount of the fee at the Prime Rate in effect on the date the payment should have been made.

10.3. Payment of Termination Fee. As promptly as practicable after payment of the Company Termination Fee (as defined in the Merger Agreement) to be paid pursuant to the terms of the Merger Agreement to the joint bank account, Parent and Buyer will reasonably agree upon the amount of the Termination Fee (subject to the limitations thereon as set forth in the definition of Termination Fee set forth herein) to be paid to Buyer, and upon such agreement Buyer and Parent shall jointly direct payment of the agreed-upon Termination Fee to Buyer and disbursement of the remaining amount in such joint account to Parent.

1-LA/903877.26

10.4.

Remedies upon Termination. If this Agreement is terminated as provided herein:

(a) ARTICLE XI (other than Section 11.2, Section 11.3 and Section 11.5) and the agreements of the Parties contained in Section 8.2(b), Section 8.2(d), Section 8.3, Section 10.2, Section 10.3 and Section 10.4 will survive the termination of this Agreement.

(b) Notwithstanding anything to the contrary herein, in view of the difficulty of determining the amount of damages which may result from a termination of this Agreement and the failure of the Parties to consummate the transactions contemplated by this Agreement under circumstances in which a termination fee is payable as contemplated by Section 10.2, Buyer, Parent, Merger Sub and Seller have mutually agreed that the payment of the termination fees as set forth in Section 10.2 will be made as liquidated damages, and not as a penalty. In the event of any such termination, the Parties have agreed that the payment of the applicable termination fee as set forth in Section 10.2 will be the sole and exclusive remedy for monetary damages of Buyer. ACCORDINGLY, THE PARTIES HEREBY ACKNOWLEDGE THAT (i) THE EXTENT OF DAMAGES CAUSED BY THE FAILURE OF THIS TRANSACTION TO BE CONSUMMATED WOULD BE IMPOSSIBLE OR EXTREMELY DIFFICULT TO ASCERTAIN UNDER CIRCUMSTANCES IN WHICH A TERMINATION FEE IS PAYABLE AS CONTEMPLATED BY SECTION 10.2, (ii) THE AMOUNT OF THE TERMINATION FEE CONTEMPLATED IN SECTIONS 10.2 AND 10.3 IS A FAIR AND REASONABLE ESTIMATE OF SUCH DAMAGES UNDER THE CIRCUMSTANCES, AND (iii) RECEIPT OF SUCH TERMINATION FEE BY BUYER DOES NOT CONSTITUTE A PENALTY. THE PARTIES HEREBY FOREVER WAIVE AND AGREE TO FOREGO TO THE FULLEST EXTENT PERMITTED UNDER APPLICABLE LAW ANY AND ALL RIGHTS THEY HAVE OR IN THE FUTURE MAY HAVE TO ASSERT ANY CLAIM DISPUTING OR OTHERWISE OBJECTING TO ANY OR ALL OF THE FOREGOING PROVISIONS OF THIS SECTION 10.4(b). Any payment under Section 10.2 will be made by wire transfer of same day funds to a bank account in the United States of America designated in writing by the Parties entitled to receive such payment not later than three (3) Business Days following the date such Party delivers notice of such account designation to the Party responsible to make such payment.

(c) Upon any termination of this Agreement, all filings, applications and other submissions made pursuant to this Agreement, to the extent practicable, will be withdrawn from the Governmental Entity or other Person to which they were made.

ARTICLE XI.

MISCELLANEOUS PROVISIONS

11.1. Survival. None of the covenants or agreements of Seller, Buyer, Parent or Merger Sub contained in this Agreement will survive the Closing, except for this ARTICLE XI and those covenants and agreements contained herein that by their terms apply or are to be performed in whole or in part after the Closing. Except as specified in the foregoing sentence, all other representations, warranties, covenants and agreements in this Agreement will not survive the Closing of this Agreement.

1-LA/903877.26

11.2. Amendment and Modification. This Agreement may be amended, modified, or supplemented only by a written agreement executed and delivered by duly authorized officers of Seller, Parent and Buyer.

11.3. Waiver of Compliance. Except as otherwise provided in this Agreement, any failure of a Party to comply with any obligation, covenant, agreement, or condition herein may be waived by the Party entitled to the benefits thereof only by a written instrument signed by the Party granting such waiver, but such waiver or failure to insist upon strict compliance with such obligation, covenant, agreement, or condition will not operate as a waiver of, or estoppel with respect to, any subsequent or other failure.

11.4. Notices. Notices, requests, instructions or other documents to be given under this Agreement must be in writing and will be deemed given, (a) when sent if sent by facsimile, provided that the fax is promptly confirmed by telephone confirmation thereof, (b) when delivered, if delivered personally to the intended recipient, and (c) one (1) Business Day later, if sent by overnight delivery via a national courier service, and in each case, addressed to a Party at the following address for such Party:

11.5. Assignment. This Agreement and all of the provisions hereof will be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns, but neither this Agreement nor any of the rights, interests, or obligations hereunder may be assigned by any Party, without the prior written consent of the other Parties, nor is this Agreement intended to confer upon any other Person except the Parties any rights or remedies hereunder. Notwithstanding the foregoing, Buyer, upon written notice to but without the consent of Seller, Parent or Merger Sub, may assign this Agreement or the rights, benefits and obligations described herein to one or more wholly-owned Subsidiaries formed or to be formed to operate as a regulated utility in each of Iowa, Kansas and Nebraska; provided, however, that notwithstanding such assignment, Buyer shall retain and remain responsible for all obligations and liabilities of Buyer hereunder; provided, further, that Buyer shall consult with Seller regarding the structure, financing and other attributes of such Subsidiaries to reflect requirements of the IUB, KCC or NPSC.

11.6. No Third Party Beneficiaries. This Agreement is not intended to, and does not, confer upon any Person other than Buyer, Seller, Parent and Merger Sub, any rights or remedies hereunder. Without limiting the generality of the foregoing, no provision of this Agreement creates any third party beneficiary 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 employee or former employee of Seller (including any beneficiary or dependent thereof) in respect of any benefits

1-LA/903877.26

that may be provided, directly or indirectly, under any employee benefit plan or arrangement except as expressly provided for under such plans or arrangements.

11.7.

GOVERNING LAW AND VENUE; WAIVER OF JURY TRIAL.

(a) THIS AGREEMENT WILL BE DEEMED TO BE MADE IN AND IN ALL RESPECTS SHALL BE INTERPRETED, CONSTRUED AND GOVERNED BY AND IN ACCORDANCE WITH THE LAW OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO THE CONFLICTS OF RULES THEREOF. The Parties hereby irrevocably submit exclusively to the jurisdiction of the State of Delaware and agree not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof, that it is not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof may not be appropriate or that this Agreement may not be enforced in or by such courts, and each of Seller, Buyer, Parent and Merger Sub irrevocably agrees that all claims with respect to such action or proceeding will be heard and determined in Delaware state court. Each of Seller, Buyer, Parent and Merger Sub hereby consents to and grants any such court jurisdiction over the Person of such Parties and over the subject matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 11.4 or in such other manner as may be permitted by Law, will be valid and sufficient service thereof.

(b) EACH OF SELLER, BUYER, PARENT AND MERGER SUB ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT THE PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH OF SELLER, BUYER, PARENT AND MERGER SUB CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT THE OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 11.7(b).

11.8. Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction will not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

11.9. Specific Performance. Each of Seller, Buyer, Parent and Merger Sub acknowledges and agrees that any breach of this Agreement would give rise to irreparable harm for which monetary damages would not be an adequate remedy. Each of Seller, Buyer, Parent and Merger Sub accordingly agrees that, in addition to other remedies, the Parties will be entitled

1-LA/903877.26

to enforce the terms of this Agreement by decree of specific performance without the necessity of providing the inadequacy of monetary damages as a remedy and to obtain injunctive relief or other equitable remedy against any breach or threatened breach hereof.

11.10. Entire Agreement. This Agreement will be a valid and binding agreement of the Parties only if and when it is fully executed and delivered by the Parties, and until such execution and delivery no legal obligation will be created by virtue hereof. This Agreement, the Partnership Interests Purchase Agreement and the Merger Agreement (in each case together with the Schedules and Exhibits hereto or thereto, and the certificates and instruments delivered pursuant hereto or thereto), the Confidentiality Agreement, the confidentiality agreement dated June 28, 2006 between Seller and Parent, as amended by the letter agreement dated September 5, 2006 between Seller and Parent, the letter of intent dated November 21, 2006 between Buyer and Parent, and the Transition Services Agreement (together with the schedules thereto), embody the entire agreement and understanding of the Parties hereto in respect of the transactions contemplated by this Agreement, the Partnership Interests Purchase Agreement and the Merger Agreement, and supersede all prior agreements, understandings, representations and warranties, both written and oral, between or among the Parties or any of them with respect to the transactions contemplated herein, in the Partnership Interests Purchase Agreement and the Merger Agreement.

11.11. Bulk Sales or Transfer Laws. Buyer and Parent acknowledge that Seller will not comply with the provisions of any bulk sales or transfer laws of any jurisdiction in connection with the transactions contemplated by this Agreement. Buyer hereby waives compliance by Seller with the provisions of the bulk sales or transfer laws of all applicable jurisdictions.

11.12. No Consequential Damages. Notwithstanding anything to the contrary elsewhere in this Agreement or provided for under any applicable Law, no Party will, in any event, be liable to any other Party, either in contract, in tort or otherwise, for any consequential, incidental, indirect, special, or punitive damages of such other Party or Persons represented by such other Party, whether or not the possibility of such damages has been disclosed to such other Party or Persons represented by such other Party in advance or could have been reasonably foreseen by such other Party or Persons represented by such other Party. The preceding sentence shall not limit the right of any Party to seek “benefit of the bargain” damages for a breach of this Agreement or specific performance or other equitable remedy as provided in Section 11.9; provided that the right of any Party or Persons represented by such Party to seek any of such remedies is not an admission by the other Parties that, under the circumstances, any such remedies are proper remedies; provided, further, that the Party against whom any such remedy is sought may not claim that the awarding of “benefit of the bargain” damages is prohibited by virtue of the restriction against liability for consequential, incidental, indirect, special or punitive damages contained in this Section 11.12.

11.13. Counterparts. This Agreement, and any certificates and instruments delivered under or in accordance herewith, may be executed in any number of counterparts (including by facsimile or other electronic transmission), each such counterpart being deemed to be an original instrument, and all such counterparts will together constitute the same instrument, it being understood that all of the Parties need not sign the same counterpart.

Exhibit 8.8(d)(ii)(C)

Pension and Benefit Matters

The following terms will govern the Parties’ obligations under Section 8.8(d)(ii)(C) of the Agreement (and any reference to Section 8.8 will be deemed to include a reference to this Exhibit):

A.	Post-Closing Spin-Off to Buyer Plan.
(1)	Transfer of Liabilities.

(a) As of the Closing Date, Buyer will cause a Buyer Pension Plan to accept the liabilities for benefits under the Seller Pension Plan that would have been paid or payable (but for the transfer of assets and liabilities pursuant to this Paragraph A) to or with respect to the Transferred Employees and Other Plan Participants (as defined below), and Buyer will become, with respect to each Transferred Employee and Other Plan Participant, responsible for all benefits due under the Seller Pension Plan. Buyer is assuming only the obligation to provide benefits in the amount determined in accordance with the terms of the Seller Pension Plan, and Buyer is not assuming any other liability or obligation that Seller or an ERISA Affiliate of Seller might have or incur with respect to the Seller Pension Plan, including liability (if any) for breaches of fiduciary duty or other penalty or excise Tax amounts. Seller will not, and Parent will not permit Seller’s successor to, take any action to fully vest the Business Employees in their accrued benefits under the Seller Pension Plan; provided that any vesting of Business Employees in such accrued benefits in the ordinary course in accordance with the Seller Pension Plan as in effect on the date hereof shall not be deemed a violation of this Paragraph A(1). Buyer will not amend the Buyer Pension Plan, or permit the Buyer Pension Plan to be amended, to eliminate any benefit accrued as of the Closing Date, whether or not vested, with respect to which liabilities are transferred pursuant to this Paragraph A; provided that Buyer may amend the Buyer Pension Plan or permit the Buyer Pension Plan to be amended to eliminate an optional form of distribution to the extent that such action is consistent with applicable Law, including the regulations under section 411(d)(6) of the Code. Notwithstanding any other provision of this Agreement, Seller will, or Parent will cause Seller’s successor to, cause the Seller Pension Plan to continue to make all benefit payments to Transferred Employees and Other Plan Participants due under the Seller Pension Plan until both the Initial Transfer Amount and the True-Up Amount have been transferred to the Buyer Pension Plan, following which transfer the Buyer Pension Plan shall make all benefit payments to or in respect of Transferred Employees and Other Plan Participants. “Other Plan Participants” means any individuals (x) who have an accrued benefit under the Seller Pension Plan but who are not actively employed by Seller on the Closing Date, or whose employment is terminated by Seller on the Closing Date, and (y) whose employment was principally associated with the Natural Gas Businesses, all of whom are listed on Schedule 8.8(d)(ii)-A, or will be listed on such Schedule as the same is amended by Seller, with Buyer’s and Parent’s consent, on the Closing Date.

(b) As soon as practicable but in any event within thirty (30) days after the Closing Date, Seller will, or Parent will cause Seller’s successor to, deliver to Buyer a list reflecting each Transferred Employee’s service and compensation under the Seller Pension Plan, each Transferred Employee’s and Other Plan Participant’s accrued benefit thereunder as of the

1-LA/903877.26

Closing Date, a copy of each pending or final domestic relations order affecting the benefit of any Transferred Employee or Other Plan Participant, and such other information as may be reasonably requested by Buyer consistent with applicable Law to facilitate or assist with such transition or the establishment of necessary records.

(2)	Transfer of Assets.

(a) Not later than ten (10) days after the Closing, Seller will, or Parent will cause Seller’s successor to, direct its actuary to determine the amount of assets allocable to the benefits with respect to the Transferred Employees and Other Plan Participants in the Seller Pension Plan based on section 4044 of ERISA and the Pension Benefit Guaranty Corporation regulations promulgated thereunder, and in compliance with section 414(l) of the Code using the safe harbor assumptions thereunder (the “Section 4044 Amount”), measured as of the Closing Date. The actuarial assumptions used in the Section 4044 Amount determination shall be limited to the safe harbor assumptions specified under Section 4.14(l) of the Code. Seller will, or Parent will cause Seller’s successor to, provide the information used to compute the Section 4044 Amount for review by Buyer’s actuary before such amount is transferred.

(b) In accordance with the procedures set forth in this Paragraph A(2)(b), Seller will, or Parent will cause Seller’s successor to, cause cash (or other assets as Seller or its successor and Buyer mutually agree) equal to the Section 4044 Amount to be transferred to the trust established by Buyer as part of the Buyer Pension Plan (the “Buyer Pension Plan Trust”). On the Initial Transfer Date, Seller will, or Parent will cause Seller’s successor to, cause the trust which is a part of the Seller Pension Plan (the “Seller Pension Plan Trust”) to make a transfer of cash or other assets as Seller or its successor and Buyer mutually agree equal to the Initial Transfer Amount to the Buyer Pension Plan Trust. The “Initial Transfer Date” is the date that is twenty (20) Business Days after the requirements of Paragraphs A(2)(d) and A(2)(e) have been met. The “Initial Transfer Amount” means 75% of Seller’s or its successor’s good faith estimate of the Section 4044 Amount. As soon as practicable after the Section 4044 Amount is determined in accordance with the requirements of Paragraph A(2)(a), and in no event more than sixty (60) days after such final determination, the True-Up Amount shall be transferred as provided below (the “True-Up Date”). If the Section 4044 Amount adjusted for earnings and losses of the assets of the Seller Pension Plan from the Closing Date through the True-Up Date (the “Increased Section 4044 Amount”), is greater than the Reduction Amount adjusted for earnings and losses of the assets of the Seller Pension Plan from the Closing Date through the True-Up Date (the “Increased Reduction Amount”), then Seller will, or Parent will cause Seller’s successor to, cause a transfer in cash or other assets as Seller or its successor and Buyer mutually agree equal to the True-Up Amount to be made from the Seller Pension Plan Trust to the Buyer Pension Plan Trust. If the Increased Reduction Amount is greater than the Increased Section 4044 Amount, then Buyer will cause a transfer in cash or other assets as Seller or its successor and Buyer mutually agree equal to the True-Up Amount to be made from the Buyer Pension Plan Trust to the Seller Pension Plan Trust. The “True-Up Amount,” if any, means the difference between the Increased Section 4044 Amount and the Increased Reduction Amount. The “Reduction Amount” equals the sum of (x) the Initial Transfer Amount, plus (y) benefit payments made to any Transferred Employees and Other Plan Participants by the Seller Pension Plan after the Closing Date. For purposes of these calculations, the earnings and losses of the assets of the Seller Pension Plan from the Closing Date through the True-Up Date shall be the net investment

returns reasonably calculated by the trustee of the Seller Pension Plan for each month between the Closing Date and the True-Up Date. Seller will, or Parent will cause Seller’s successor to, provide the information used to make such calculations and compute the True-Up Amount for review by Buyer’s actuary before any such amounts are transferred.

(c) To the extent that under Section 8.8 Buyer has agreed to accept a liability of Seller under any of Seller’s Benefit Plans (other than the Seller Pension Plan) with respect to employees of Seller that are Business Employees, Transferred Employees, Current Retirees or Covered Individuals, and such Benefit Plans, including any non-qualified deferred compensation plan or agreement, is funded through or maintained in connection with a grantor trust, secular trust, Voluntary Employees’ Beneficiary Association or other trusts or arrangements used to provide benefits payable under any such plan or agreement, as promptly as practicable after the Closing, Buyer and Seller will, or Parent will cause Seller’s successor to, determine the amount of assets in such trusts or other arrangements historically allocated to the Natural Gas Businesses, the Business Employees, Transferred Employees, or other Covered Individuals with respect to liabilities assumed by Buyer, and such assets shall be transferred, to the extent consistent with the terms of any such trust as in effect on the date hereof and not contrary to applicable Law, to a similar trust or arrangement established and maintained by Buyer to fund such benefits. Seller shall use reasonable best efforts to make or cause to be made any required amendments to such trusts and agreements to provide for the transfers described in this Paragraph A(2)(c).

(d) In connection with the transfer of assets and liabilities pursuant to this Section, Seller will, or Parent will cause Seller’s successor to, provide to Buyer, and Buyer will provide to Seller or its successor, evidence reasonably satisfactory to the other Party that the other Party’s Pension Plan is or continues to be qualified under section 401(a) of the Code and is in compliance with the funding requirements of section 302 of ERISA and section 412 of the Code.

(e) In connection with the transfer of assets and liabilities pursuant to Paragraph A, Buyer and Seller will, or Parent will cause Seller’s successor to, cooperate with each other in making all appropriate filings required by the Code or ERISA in a timely manner, but not later than within thirty (30) days after the Closing Date, and the transfer of assets and liabilities from the Seller Pension Plan pursuant to this Exhibit 8.8(d)(ii)(C) will not take place until after the expiration of the thirty (30) day period following the filing of any required notices with the Internal Revenue Service pursuant to section 6058(b) of the Code.

(3) Benefits. The benefit provided by the Buyer Pension Plan to each Transferred Employee and Other Plan Participant who becomes a participant in the Buyer Pension Plan will be at least equal to the benefits accrued by such Transferred Employee or Other Plan Participant under the Seller Pension Plan on the Closing Date, computed by taking into account the service credited to such Transferred Employee and Other Plan Participant with Seller and Buyer (in the case of service of Transferred Employees with Buyer, such service will be required to be taken into account only for the purpose of vesting and early retirement subsidies or as otherwise required by applicable Law).

B.	Further Purchase Price Adjustment.

(1) Adjusted Section 4044 Amount. Seller will, or Parent will cause Seller’s successor to, also calculate the Section 4044 Amount using the same assumptions and methodologies as used to calculate the Section 4044 Amount pursuant to Paragraph A(2)(a), but adjusted to remove from the assets of the Seller Pension Plan an amount equal to Seller’s contributions to the Seller Pension Plan made between the date hereof and the Closing Date (the Section 4044 Amount so adjusted, the “Adjusted Section 4044 Amount”). Seller shall, or Parent shall cause Seller’s successor to, provide the information used to compute the Adjusted Section 4044 Amount for review by Buyer’s actuary. Buyer and Seller, or Parent will cause Seller’s successor to, cooperate in good faith and resolve and reconcile any differences or disputes with respect to the calculation of the Adjusted Section 4044 Amount as soon as practicable.

(2) Notwithstanding anything to the contrary herein, the Purchase Price (i) shall be decreased by the amount, if any, by which the Adjusted Section 4044 Amount exceeds the Section 4044 Amount, and (ii) shall be increased by the amount, if any, by which the Adjusted Section 4044 Amount is less than the Section 4044 Amount. On the earlier of the date that the True-Up Amount is transferred, or within five (5) Business Days of the date the True-Up Amount is determined, Buyer shall pay an amount equal to the amount of the increase in the Purchase Price, if any, determined pursuant to this Paragraph B, to Seller or its successor, or Seller shall, or Parent shall cause Seller’s successor to, pay an amount equal to the amount of the decrease, if any, in the Purchase Price determined pursuant to this Paragraph B, as applicable, by wire transfer of same day funds.
