Schedule 2.2.2 attached hereto sets forth a non-exclusive list of the types of accounts to be used in the calculation of Estimated Net Working Capital and Closing Net Working Capital made in accordance with the Financial Principles.

If the Closing Net Working Capital is more than the Estimated Net Working Capital, the Closing Purchase Price shall be increased by the amount by which the Closing Net Working Capital exceeds the Estimated Net Working Capital. If the Closing Net Working Capital is less than the Estimated Net Working Capital, the Closing Purchase Price shall be decreased by the amount by which Closing Net Working Capital is less than the Estimated Net Working Capital.

If the Final Working Capital Adjustment is a negative amount, then Seller shall pay the absolute value of such amount to Buyer. Any payment pursuant to this Section 2.2.2(c) shall be made by wire transfer of immediately available funds within five (5) days after Buyer’s written notification to Seller of Buyer’s acceptance of the Closing Statement or within five (5) days after Buyer is deemed (or Buyer and Seller are deemed) to have accepted the Closing Statement as provided in Section 2.2.2(e) (or Section 2.2.2(i)) or within five (5) days after the resolution of the dispute pursuant to Section 2.2.2(h). The amount of any payment required by this Section 2.2.2(c) shall bear interest from the Closing Date through the date of actual payment at the rate per annum equal to 30-day LIBOR plus 150 basis points.

After Seller’s delivery of the Closing Statement, each Party shall permit the other Party and its independent accountants access, upon reasonable notice and during reasonable business hours, to review its work papers and all books and records of the Company or of Buyer, as the case may be, relevant to the items covered by the Closing Statement, and each Party shall permit such accountants to perform such tests as they may reasonably require to confirm the accuracy of such items.

In the event Buyer disputes any matter or matters on the Closing Statement, Buyer may within thirty (30) days after the delivery of the Closing Statement notify Seller of such dispute in a writing setting forth in reasonable detail the nature of such dispute and the facts upon which it is based, together with the application or treatment proposed by Buyer and the reasons supporting the use of such application or treatment rather than that used by Seller. If both the Closing Statement as delivered by Seller to Buyer and the form of closing statement as proposed by Buyer would require a payment by the same Party pursuant to Section 2.2.2(c), then, notwithstanding the amount in dispute (which shall be resolved in accordance with Sections 2.2.2(f) – (i)), such Party shall make a payment of the undisputed portion of such amount within five (5) days of delivery to Seller of Buyer’s notice and proposed form of closing statement,

together with interest thereon as provided by Section 2.2.2(c). If no such notice is given by Buyer within the time specified, the Closing Statement shall be deemed accepted by Buyer.

In the event that the Parties are unable to resolve any disagreement with respect to any amount remaining in dispute pursuant to Section 2.2.2(e) within the ten (10) day period after Buyer’s delivery to Seller of Buyer’s notice and proposed form of closing statement (the “Ten Day Period”), then Buyer, on the one hand, and Seller, on the other hand, shall each promptly nominate (and in any event within five (5) Business Days following the expiration of the Ten Day Period) an officer from their respective senior management teams to use commercially reasonable efforts to resolve such amount in dispute on or before the tenth day following the date of such nomination. If such senior management representatives fail to resolve any such dispute within thirty (30) days after Seller’s receipt of the notice of dispute from Buyer pursuant to Section 2.2.2(e), then either Party may elect to refer such remaining issues to a neutral accounting firm for resolution pursuant to the procedures set forth in the following Sections 2.2(g), (h) and (i).

If the Parties have not resolved all matters in dispute relating to the Closing Statement within thirty (30) days after Seller’s receipt of the notice of dispute from Buyer pursuant to Section 2.2.2(e), then either Party may notify the other in writing that it elects to submit all remaining issues to resolution by a neutral accounting firm of national reputation. Within ten (10) days after receipt of such notice of election by a Party, the Parties shall agree upon the selection of a neutral accounting firm or, if they are unable to agree, Seller and Buyer shall each submit the names of two neutral firms and a firm shall be selected at random from among them. A firm shall be considered neutral if it has not within the past three (3) years performed and does not currently perform or contemplate performing any accounting, consulting or other services having an aggregate value in excess of $250,000 for either of the Parties and their respective Affiliates. In the event that the Parties are unable to identify an accounting firm of national reputation that is neutral, then either Party may apply to the American Arbitration Association for the appointment of a qualified neutral accountant.

As soon as reasonably practicable, the firm selected shall resolve all matters remaining in dispute solely on the basis of the Financial Principles and the provisions of this Section 2.2.2. Such firm shall not be required to follow any particular rules of procedure, it being the intention of the Parties to create a feasible, practical and expeditious method for resolving any disagreement hereunder. In this regard, the Parties agree to use their commercially reasonable best efforts to enter into any “agreed-upon-procedures” agreement or similar arrangement with such accounting firm to assist in such resolution. The decision of such firm hereunder shall be final and binding and shall not be subject to review or challenge of any kind. The appropriate Party shall pay to the other any disputed amount that is determined to be due within five (5) days after such determination, together with interest thereon as provided by Section 2.2.2(c). The fees and expenses of such firm shall be borne equally by the Parties. It the appropriate Party does not timely pay the amount due plus interest as required by the foregoing, then the

accounting firm’s decision may be treated as an arbitration award, and the prevailing Party may seek to enforce the decision as a final and binding arbitration award.

If the Parties resolve all matters in dispute relating to the Closing Statement, then the Closing Statement shall be adjusted as required by the agreement resolving the matters in dispute and the Closing Statement as so modified shall be deemed accepted by Buyer and Seller.

Time and Place. The closing of the transactions contemplated hereby (the “Closing”) shall take place at the offices of Seller, 2350 N. Sam Houston Parkway E., Houston, Texas 77032, at 11:00 a.m., Central Time (or at such other place and time as Buyer and Seller shall agree), on the third Business Day following the date on which all of the conditions specified in Articles IX and X hereof (other than those conditions that by their nature are to be satisfied at the Closing, and subject to the satisfaction or due waiver of such conditions at the Closing) have been satisfied or waived.

No broker or finder has acted directly or indirectly for Buyer in connection with this Agreement or the transactions contemplated hereby, and no broker or finder is entitled to any brokerage or finder’s fee or other commission in respect thereof based in any way on agreements, arrangements or understandings made by or on behalf of Buyer.

Litigation. There is no legal, administrative or other action, proceeding or, to the Knowledge of Buyer, governmental investigation either pending or, to the Knowledge of Buyer, filed but not yet served, or otherwise threatened, (i) against Buyer, or (ii) which seeks to enjoin or obtain damages in respect of the consummation of the transactions contemplated hereby, which, in either case, if decided adversely, would, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of Buyer to perform its obligations under this Agreement. The Buyer is not subject to any outstanding judgment, order, writ, injunction or decree that would, individually or in the aggregate, reasonably be expected to have or result in a material adverse effect on the ability of Buyer to perform its obligations under this Agreement.

Financial Ability. Buyer has, in cash or cash equivalents on hand, or will have sufficient funds in cash, to ensure timely payment in full of the Closing Purchase Price and any adjustments thereto and as may otherwise be required in order for Buyer to consummate the transactions to be performed by it contemplated under this Agreement and to satisfy all other costs, expenses and obligations of Buyer arising in connection therewith or hereunder.

Securities Law Compliance. Buyer (i) is acquiring the Shares for its own account and not with a view to distribution, and (ii) understands that the Shares will, upon purchase, be characterized as “restricted securities” under applicable state and federal securities laws and that under such laws and applicable regulations the Shares may be resold without registration under such laws only in certain limited circumstances.

Consents. Seller will, and will take all actions necessary to cause the Company to, use commercially reasonable efforts, and will cooperate with Buyer, to secure all necessary consents, approvals, authorizations, exemptions and waivers from third parties, including any Governmental Authority, as shall be required in order to enable Seller and Buyer to effect the transactions contemplated on its part hereby. Seller shall keep Buyer apprised of its efforts to obtain such consents, approvals, authorizations, exemptions and waivers and the responses of such third parties to Seller’s requests to provide such consents, approvals, authorizations, exemptions and waivers, but only to the extent that the failure to secure any such particular consents, approvals, authorizations, exemptions and waivers would, individually or in the aggregate, materially affect the Company (including its results of operations or financial condition), or the ability of either Party to perform its obligations under this Agreement in accordance with the terms hereof. To the extent that any third-party consent set forth in Schedule 3.3, Schedule 3.7 or Schedule 3.10 cannot be obtained (excluding for these purposes any consent, order, approval or waiver of any Governmental Authority), then at the request of Buyer, Seller shall use commercially reasonable efforts to enter into other arrangements which result in the Company being in the same economic position as though the consent had been obtained. To the extent required by the Hart-Scott Rodino Act (the “HSR Act”) and/or the APSC, Seller will:

File or cause to be filed, as promptly as practicable but in no event later than thirty (30) days after the execution and delivery of this Agreement, with the Federal Trade Commission and the United States Department of Justice, all reports and other documents required to be filed by Seller under the HSR Act concerning the transactions contemplated hereby;

Promptly comply with, or cause to be complied with, any requests by the Federal Trade Commission, the United States Department of Justice or any other Governmental Authority in respect of such filings or transactions, for additional information concerning such transactions, in each case so that the waiting period applicable to this Agreement and the transactions contemplated hereby under the HSR Act shall expire as promptly as practicable after the execution and delivery of this Agreement; and

Cooperate with Buyer in causing to be filed, as promptly as practicable after the execution and delivery of this Agreement, all applications, reports and other documents required to be filed jointly by the Parties with the APSC concerning the transactions contemplated hereby (collectively, the “Joint Filings”), which applications, reports and other documents (together with the Seller Filings) shall be in form and substance reasonably satisfactory to Seller in its sole good faith and reasonable discretion.

Notwithstanding anything to the contrary contained in this Agreement or otherwise, all applications, reports and other documents submitted or to be submitted by Seller or the Company

to the APSC with respect to the transactions contemplated by this Agreement (collectively, the “Seller Filings”) shall be submitted together with and as part of the applications, reports and other documents submitted or to be submitted by Buyer to the APSC with respect to the transactions contemplated by this Agreement (collectively, the “Buyer Filings”), it being the intention of the Parties that all the Seller Filings and such Buyer Filings shall be filed jointly by the Parties unless Buyer otherwise agrees in writing.

In addition, to the extent permitted by Law, Seller will (i) promptly provide Buyer with copies of all correspondence between it and any of its Subsidiaries (or its or their representatives) and the APSC relating to the transactions contemplated by this Agreement, (ii) consult and cooperate with Buyer, and take into account the comments of Buyer in connection with any such Seller Filings (including correspondence), (iii) promptly furnish Buyer with copies of any notice or other communication received by it or its Subsidiaries from the APSC or any of its representatives with respect to the transactions contemplated by this Agreement and (iv) inform Buyer, to the extent practicable, reasonably in advance of any communication, meeting, or other contact of which Seller or the Company has received notice, or which Seller or the Company proposes or intends to make, with respect to any such filings or correspondence, 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 the APSC regarding the transactions contemplated by this Agreement will include representatives of both Seller and Buyer; provided, however, that nothing contained in the foregoing will apply to or restrict communications or other actions by Seller with or with regard to the APSC in connection with the Company or the operations of the Company in its ordinary course of business. To the extent permitted by Law, Seller shall otherwise keep Buyer apprised of the status of matters concerning the APSC relating to the transactions contemplated by this Agreement.

Seller shall request, and use its commercially reasonable efforts to cooperate with Buyer in requesting, early termination of any applicable waiting period under the HSR Act. Notwithstanding anything contained herein to the contrary, this Section 5.1 shall not be deemed to require Seller or any of its Subsidiaries to take or agree to take any Seller Action of Divestiture with respect to their respective assets which would be materially adverse to the business, financial condition, assets or results of operations of Seller or such Subsidiary following the Closing. For purposes of this Agreement, a “Seller Action of Divestiture” shall mean making proposals, executing or carrying out agreements providing for the license, sale or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets that are material to Seller, or any of its Subsidiaries, or imposing or seeking to impose any limitation on the ability of Seller, or any of its Subsidiaries, to conduct their respective businesses or own such assets or to acquire, hold or exercise full rights of ownership of such businesses.

Conduct of Business. (a) Except as may be otherwise contemplated by this Agreement or required by any of the documents listed in any Schedule hereto or except as Buyer may otherwise consent to in writing, between the date hereof and the Closing Date, Seller shall cause the Company to:

In all material respects, conduct the Company’s business only in the ordinary course consistent with past practice;

Use commercially reasonable efforts to preserve intact the Company’s business and the goodwill of its customers, suppliers, employees and any other Persons having business relations with them;

Use commercially reasonable efforts to conduct business of the Company in such a manner so that the representations and warranties of Seller contained herein shall continue to be true and correct at all times prior to the Closing Date as if made on and as of such times; and

Use commercially reasonable efforts to make the capital expenditures in accordance with Schedule 2.2.2(a) attached hereto and the Company shall have or shall have access to sufficient funds in order to make such capital expenditures.

Without limiting the generality of the foregoing, except as set forth on Schedule 5.2 or as Buyer may otherwise consent to in writing, Seller shall not permit the Company to:

(A) Enter into any contract or agreement that would have constituted a Material Contract had it been in existence as of the date hereof other than Material Contracts of the type entered into in the Company’s ordinary course of business consistent with past practice or (B) amend, terminate or modify, or provide any waiver or consent under, any such contract or agreement or any Material Contract other than any amendment, modification, waiver or consent in the Company’s ordinary course of business consistent with past practice;

Adopt, amend or terminate any Plan, increase any salary, bonus or other compensation or benefit, or promise or commit to do any of the foregoing, except in a manner which individually or in the aggregate will not result in a material increase in benefits or compensation expense, provided, that, notwithstanding the immediately preceding provision of this Section 5.2(b)(ii), in no event will the Company or Seller amend, modify or alter in any other manner any Assumed Plan without the prior written consent of Buyer, which consent will not be unreasonably withheld;

Amend or otherwise change its charter or bylaws or equivalent organizational documents;

(A) Issue, sell, pledge, dispose of, redeem, purchase, acquire, grant, encumber or authorize the issuance, sale, pledge, disposition, redemption, purchase, acquisition or grant of any shares of capital stock of any class of the Company, or any options, warrants, convertible securities or other rights of any kind to acquire any shares of such capital stock, or any other equity interest (including, without limitation, any phantom interest) of the Company, or (B) sell, pledge, dispose of, encumber, purchase, acquire or authorize the sale, pledge, disposition, encumbering, purchase or acquisition of

any assets and properties material to the Company other than in the Company’s ordinary course of business consistent with past practice or as contemplated herein;

(A) Incur any indebtedness for borrowed money or issue any debt securities or assume, guarantee or endorse, or otherwise as an accommodation become responsible for, the obligations of any Person, except for borrowings from Seller or (B) make any loans or advances except for loans to customers in connection with financing the sale of appliances, in either case, in the Company’s ordinary course of business consistent with past practice;

Enter into any contract that restrains, restricts, limits or impedes the ability of the Company to compete with or conduct any business or line of business in any geographic area or solicit the employment of any person;

Settle or compromise any pending or threatened proceeding or any claim or claims for, or that would result in an uninsured loss by the Company following the Closing of, an amount that could, individually or in the aggregate, reasonably be expected to be greater than $250,000;

other than (A) to the extent necessary to satisfy the Company’s obligations under applicable Law or (B) in response to an emergency situation as is reasonably necessary to protect human health or safety, or the environment, or to provide for continuation of the operations and business of the Company, in each case as determined by Seller or the Company, in its reasonable discretion, make or commit to make any capital expenditure not provided for in Schedule 2.2.2(a) in excess of $100,000 per month prior to the Closing;

Settle any dispute with the APSC involving a potential cost, loss, reimbursement or liability greater than $250,000 in the aggregate; provided, however,

that the foregoing shall not preclude or affect the Company’s rights to settle any dispute (if any) with respect to the Gas Cost Compliance Audit prior to the Closing to the extent the settlement involves only the payment of money to the APSC or other parties prior to the Closing and all such money is so paid by Seller or the Company (or the Company has recorded such amount to deferred gas purchases, other deferred credits or a similar account or accounts, to the extent such amount is taken into account as a negative adjustment to Net Working Capital for purposes of Section 2.2.1 or post-Closing adjustments pursuant to Section 2.2.2) prior to the Closing without right of reimbursement by the Company from and after the Closing;

Hire any new employees other than to fill vacancies in existing positions in the reasonable discretion of Seller and Seller will not (and will cause its Affiliates not to) hire or otherwise transfer any Company employee other than hires or transfers in process as of the date hereof as described on Schedule 5.2;

Engage in any mass layoff, plant closing or other group terminations that would create any liability under the Worker Adjustment and Retraining Notification Act or any similar state or local Law; or

Enter into any agreement or commitment to take any of the actions described in clauses (i) through (xv) above.

Access Before Closing. From the date of this Agreement until the Closing Date, subject to the Confidentiality Agreements, Seller will cause the Company to permit Buyer and its representatives reasonable access on reasonable advance notice during normal business hours to the properties, personal property, personnel, books and records, contracts and commitments of the Company, including in connection with Buyer’s review of the statement referred to in Section 2.2.1 (as well as access to the personnel, books and records, contracts and commitments of Seller and its Affiliates as may be appropriate for purposes of Buyer evaluating whether it may want any of the Hedging Agreements to be novated pursuant to Section 8.13). In the event that any record or other information requested by Buyer is subject to a confidentiality agreement with a third party, attorney-client privilege or other legal restriction or privilege, Seller and Buyer will endeavor to find means of disclosing as much information as practicable that is needed by Buyer to prepare for the transfer of the Shares, but Seller and the Company will not be obligated to breach any such restriction or privilege. In the event this Agreement shall be terminated, (i) Buyer shall not utilize any such information or material, directly or indirectly, (ii) all such information shall be destroyed or returned to Seller and (iii) Buyer shall certify to Seller that such information has either been destroyed or returned to Seller.

Rate and Regulatory Matters. To the extent permitted by applicable Law, Seller will cause the Company to deliver to Buyer a copy of each principal filing or agreement (other than filings or agreements related to a fuel adjustment or purchase gas adjustment or similar adjusting rate mechanism) related to its generally applicable rates, charges, standards of service, accounting or regulatory policy which could lead to a material change in any of those areas as soon as practicable and in any event no later than five (5) Business Days prior to the filing or execution thereof so that Buyer may comment thereon; provided, however, that the foregoing shall not be construed such that Buyer’s consent is required by Seller or the Company

as to any such filing or agreement. Seller will cause the Company to make all such filings only in the ordinary course of business consistent with past practice or as required by a Governmental Authority or regulatory agency with appropriate jurisdiction or under existing settlement agreements to which the Company is a party.

Contracts. Following the execution of this Agreement and until the Closing Date, Seller shall promptly provide Buyer copies of (i) all contracts or agreements entered into during such period that would have constituted Material Contracts had they been in existence as of the date hereof and (ii) any amendments, renewals, extensions, supplements or other modifications thereto or to any Material Contracts.

No Shop. Following the execution of this Agreement and until the Closing Date, Seller shall not (and shall not permit any Affiliate thereof to) directly or indirectly take (or authorize or permit its or their respective officers, directors, principals, attorneys, employees, agents, consultants, accountants or other representatives to take) any action to (i) solicit or initiate, or encourage the submission of, proposals or offers relating to, (ii) respond to any submissions, proposals, offers or inquiries relating to, (iii) engage in any negotiations or discussions with any Person relating to, or (iv) otherwise cooperate in any way with any Person in connection with, any disposition, acquisition, recapitalization, liquidation, dissolution or similar transaction involving all or any portion of the Shares or the business or assets of the Company (whether structured as an asset sale, stock sale, sale of interests, merger, equity issuance, recapitalization or otherwise).

Resignation of Designated Officers and Directors at Closing. Seller agrees to use commercially reasonable efforts to cause each member of the board of directors (or similar governing body) of the Company designated in writing by Buyer not later than three (3) Business Days prior to the Closing Date and each officer of the Company set forth in Schedule 5.7 (the “Designated Employees”) to execute and deliver to the Company on the Closing Date (with a copy to Buyer) a written resignation in the form attached hereto as Exhibit G which resignation shall be effective immediately prior to the effectiveness of the Closing (each such resignation, a “Resignation”). At the Closing, Seller shall deliver to Buyer a list of each such designated member of the board of directors (or similar governing body) and each such designated officer of the Company who has not executed and delivered a Resignation to the Company.

Financial Statements. Seller shall provide Buyer copies of monthly and annual financial statements for the Company as soon as practicable but in any event within fifteen (15) Business Days after the end of each calendar month and within forty-five (45) Business Days after the end of 2007 (such reports to be in the form prepared by the Company in the ordinary course of business consistent with past practice). For the avoidance of doubt, the first monthly financial statement shall be prepared for October 2007.

Subject in all respects to Section 5.9(b) below, in order to assist with obtaining any third party debt and equity financing (the “Financing”), at Buyer’s sole cost and expense, prior to Closing Seller and the Company shall use commercially reasonable efforts to provide such assistance and cooperation as Buyer may reasonably request, all

subject to and in accordance with the terms of this Section; provided, however, that such requested cooperation does not unreasonably interfere with the ongoing operations of the Company or of Seller and its Subsidiaries considered as a whole (collectively, the “Seller Cooperation”). To the extent Buyer has so requested, and Seller is providing, assistance and cooperation with respect to a Financing, if Buyer becomes aware of any event or circumstance that makes procurement of the Financing impossible or unlikely to occur, Buyer shall notify Seller thereof as promptly as practicable. Seller shall cause the Company to provide, and shall use commercially reasonable efforts to cause Seller’s representatives, including legal and accounting, to provide the Seller Cooperation, including (i) assisting in preparing any information memorandum or similar document or marketing material, and, cooperating with one or more arrangers and agents for the Financing, (ii) making senior management of the Company reasonably available for customary syndication presentations and calls, lender or proposed financing source meetings and rating agencies presentations and (iii) cooperating with prospective lenders, equity investors and their respective advisors in performing their due diligence; provided, however, that, except as expressly provided in this Section 5.9, (x) no obligation of Seller or any of its Subsidiaries under this Section 5.9(a) shall be effective after the Closing Date and (y) none of Seller, the Company or any of Seller’s Subsidiaries shall be required to pay any commitment or other similar fee or incur any other liability in connection with the Financing. In addition, at Buyer’s sole cost and expense, Seller shall use commercially reasonable efforts to cause the preparation and delivery to Buyer as soon as reasonably practicable of audited financial statements for the Company and such other financial data of the type required by Regulations S-X and S-K under the Securities Act of 1933, as amended, for calendar years 2005, 2006 and 2007 and the first quarter of 2008. In the event that the Closing occurs and all of the financial statements and other financial data referred to in the immediately preceding sentence have not been prepared and delivered to Buyer pursuant to this Section 5.9(a), Seller will continue to provide the Seller Cooperation and cause such financial statements and other financial data to be prepared and delivered to Buyer as soon as practicable after the Closing, subject to and in accordance with the terms of this Section 5.9 at Buyer’s sole cost and expense.

Notwithstanding any provision contained herein to the contrary, (i) nothing contained in Section 5.9(a) above shall be deemed to affect Buyer’s representation pursuant to Section 4.7 of this Agreement, and (ii) the failure to timely deliver any financial statements referred to in Section 5.9(a) shall under no circumstances, by itself be deemed a failure of Seller or any of its Affiliates to satisfy any of the conditions under Article IX of this Agreement to Buyer’s obligations to consummate the transactions contemplated hereunder.

Non-Solicitation. Except as set forth in Schedule 5.10, from the date hereof and continuing for a period of twelve (12) months from and after the Closing Date, Seller shall not, and shall cause its directors, officers, employees and Affiliates not to, directly or indirectly (i) cause, solicit, induce or encourage any employees of the Company to leave such employment or hire, employ or otherwise engage any such individual or (ii) cause, induce or encourage any material actual or prospective client or customer of the Company (including any existing or former customer of the Company, or any other Person who has a material business relationship with the Company, to terminate or modify any such actual or prospective relationship; provided

however, that nothing contained herein shall limit the right of Seller or any Seller Affiliate to solicit any existing retail sales customer of the Company to purchase natural gas from Seller or any Seller Affiliate so long as such retail sales customer remains a distribution customer of the Company.

Insurance. To the extent the Company is covered under any of the Policies set forth in Schedule 3.17 that is an “occurrence” insurance policy, the Company shall continue to be covered by such insurance policy after the Closing with respect to claims made by or on behalf of the Company before or after the Closing. To the extent claims are, or can be, made by the Company after Closing relating to occurrences or circumstances prior to the Closing, Seller shall cooperate with and assist the Company in making claims and enforcing rights under such Policies. Seller shall not terminate or amend such Policies in a manner that terminates or otherwise adversely affects the Company’s rights under any such Policy with respect to any pre-Closing occurrences or circumstances.

Natural Gas Service Agreement. Seller shall cause SEECO, Inc. to execute and deliver to Buyer the Natural Gas Service Agreement.

Bill of Sale. Seller shall promptly following the date hereof cause the Bill of Sale and Assignment of Public Utility Property dated as of July 24, 1978 (the “Bill of Sale”) by the entity then known as Arkansas Western Gas Company and accepted as of July 24, 1978 by Arkansas Utility Company to be promptly recorded in each county in Arkansas in which any real property, fixtures or similar interests set forth in the Bill of Sale were located and, promptly following each such recordation, deliver evidence thereof to Buyer.

Consents. Buyer will use commercially reasonable efforts, and will cooperate with Seller and the Company, to secure all necessary consents, approvals, authorizations, exemptions and waivers from third parties, including any Governmental Authority, as shall be required in order to enable Buyer to effect the transactions contemplated hereby. Buyer shall keep Seller apprised of its efforts to obtain such consents, approvals, authorizations, exemptions and waivers and the responses of such third parties to Buyer’s requests to provide such consents, approvals, authorizations, exemptions and waivers, but only to the extent that the failure to secure any such particular consents, approvals, authorizations, exemptions and waivers would, individually or in the aggregate, materially affect the ability of either Party to perform its obligations under this Agreement in accordance with the terms hereof. To the extent required by the HSR Act and the APSC, Buyer will:

File or cause to be filed, as promptly as practicable but in no event later than thirty (30) days after the execution and delivery of this Agreement, with the Federal Trade Commission and the United States Department of Justice, all reports and other documents required to be filed by Buyer under the HSR Act concerning the transactions contemplated hereby;

Cooperate with Seller in causing to be filed, as promptly as practicable after the execution and delivery of this Agreement, the Joint Filings, which applications, reports and other documents (together with the Buyer Filings) shall be in form and substance reasonably satisfactory to Buyer in its sole good faith and reasonable discretion.

Notwithstanding anything to the contrary contained in this Agreement or otherwise, all Buyer Filings shall be submitted to the APSC together with and as part of the Seller Filings, it being the intention of the Parties that all the Seller Filings and such Buyer Filings shall be filed jointly by the Parties unless Seller otherwise agrees in writing.

In addition, to the extent permitted by Law, Buyer will promptly (i) provide Seller with copies of all correspondence between it and any of its Subsidiaries (or its or their representatives) and the APSC relating to the transactions contemplated by this Agreement, (ii) consult and cooperate with Seller, and take into account the comments of Seller in connection with any such Buyer Filings (including correspondence), (iii) promptly furnish Seller with copies of any notice or other communication received by it or its Subsidiaries from the APSC or any of its representatives with respect to the transactions contemplated by this Agreement and (iv) inform Seller, to the extent practicable, reasonably in advance of any communication, meeting, or other contact of which Buyer has received notice, or which Buyer proposes or intends to make, with respect to any such filings or correspondence, 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 the APSC regarding the transactions contemplated by this Agreement will include representatives of both Buyer and Seller; provided, however, that nothing contained in the foregoing will apply to or restrict communications or other actions by Seller with or with regard to the APSC in connection with the Company or the business of the Company in the ordinary course of business. To the extent permitted by Law, Buyer shall otherwise keep Seller apprised of the status of matters concerning the APSC relating to the transactions contemplated by this Agreement.

Buyer shall request, and use its commercially reasonable efforts to cooperate with Seller in requesting, early termination of any applicable waiting period under the HSR Act. Buyer shall pay the filing fees payable in connection with the filings by the Parties with the APSC and as required by the HSR Act. Notwithstanding anything contained herein to the contrary, this Section 6.1 shall not be deemed to require either Buyer, or any of its Subsidiaries to take or agree to take any Buyer Action of Divestiture with respect to their respective assets which would be materially adverse to the business, financial condition, assets or results of operations of Buyer or the Company, following the Closing (excluding, however, the loss of any cost savings or revenue enhancements expected as a result of the transactions contemplated hereunder and the

consolidated operations of Buyer and the Company thereafter). For purposes of this Agreement, “Buyer Action of Divestiture” shall mean making proposals, executing or carrying out agreements providing for the license, sale or other disposition or holding separate (through the establishment of a trust or otherwise) of any assets or categories of assets that are material to Buyer or any of its Subsidiaries or the holding separate of capital stock of the Company, or imposing or seeking to impose any limitation on the ability of Buyer or any of its Subsidiaries to conduct their respective businesses or own such assets or to acquire, hold or exercise full rights of ownership of the business of the Company.

Non-Solicitation. From the date hereof and continuing for a period of twelve (12) months from and after the Closing Date, Buyer shall not, and shall cause its directors, officers, employees and SourceGas Holdings LLC and its Subsidiaries not to (and following the Closing, shall cause SourceGas Holdings LLC and its directors, officers, employees and its Subsidiaries not to), directly or indirectly cause, solicit, induce or encourage any employees of Seller or its Affiliates (other than employees of the Company) to leave such employment or hire, employ or otherwise engage any such individual.

Natural Gas Service Agreement. Buyer shall cause the Company to execute and deliver to Seller the Natural Gas Service Agreement at the Closing.

Employment of Employees. For a period of one year after the Closing Date, Buyer shall, except in the case of the Designated Employees, cause the Company to employ each employee (unless severed pursuant to the terms of Section 7.2) set forth on Schedule 3.13.9 (referred to herein individually as a “Company Employee” and collectively as the “Company Employees”) at a base salary or hourly rate not less than the base salary or hourly rate then applicable to such Company Employee and to provide such benefits, holidays, vacation days, and similar benefits as are, in the aggregate, substantially comparable to those then in effect for such Company Employees as reasonably determined by Buyer in its sole good faith discretion. Nothing in this Section 7.1 or elsewhere in this Agreement requires Buyer or the Company to continue to employ any Company Employee for any specific period of time after the Closing Date.

Severance Benefits. For a period of one year after the Closing Date, Buyer shall, or shall cause the Company to, provide to each Company Employee who is involuntarily terminated after the Closing not for cause (as defined in Schedule 7.2 hereto) by Buyer or the Company the severance benefits set forth on Schedule 7.2 hereto.

Savings Plan. As soon as practicable following the Closing Date, Seller shall cause to be transferred (i) from the 401(k) Savings Plan of Seller (the “Seller Savings Plan”) to the 401(k) Savings Plan sponsored by Buyer or the Company (the “Buyer Savings Plan”), and the Buyer Savings Plan shall assume, the account balance liability as of the date of transfer for each Company Employee, not including the Designated Employees, who participated in the

Seller Savings Plan prior to the Closing Date (the “Eligible Company Employees”), and (ii) from the trust relating to the Seller Savings Plan, an amount in cash or other property, including participant loans, acceptable to the trustee of the Buyer Savings Plan equal to the sum of the account values (as of the date of transfer) of each Eligible Company Employee. Seller shall not be obligated to cause any amount to be transferred to the Buyer Savings Plan or the trust thereunder until Buyer provides evidence (such as a favorable determination letter from the Internal Revenue Service, an opinion of counsel or other reasonably satisfactory evidence) reasonably acceptable to Seller that such plan and trust satisfy the requirements for qualification under Section 401(a) of the Code. Each Eligible Company Employee shall be entitled on the date of transfer to a nonforfeitable account balance under the Buyer Savings Plan that is not less than such Eligible Company Employee’s nonforfeitable account balance under the Seller Savings Plan immediately prior to such transfer. Buyer agrees to permit any Eligible Company Employee who has an unpaid loan balance under the Seller Savings Plan to continue to repay such loan under the Buyer Savings Plan under the same terms as such loan was required to be repaid under the Seller Savings Plan.

Transfer. As soon as practicable following the Closing Date, but not before that date which is thirty (30) days following the filing of appropriate Forms 5310-A, if applicable, with the Internal Revenue Service, and subject to the requirements of applicable law, including Section 414(l) of the Code, Seller shall cause to be transferred (i) from the Southwestern Energy Company Pension Plan (the “Seller Pension Plan”) to the pension plan sponsored by or to be established by Buyer or the Company (the “Buyer Pension Plan”), and the Buyer Pension Plan shall assume, the Pension Liability as of the Closing Date, and shall assume responsibility for future liability which may accrue after the Closing Date, for each of the Company Employees who participated in the Seller Pension Plan prior to the Closing Date, not including the Designated Employees (the “Company Pension Plan Participants”), and (ii) from the Southwestern Energy Company Pension Trust (the “Seller Pension Plan Trust”) to the Buyer Pension Plan trust, an amount in cash equal to the aggregate amount of funds held in the Seller Pension Plan Trust for the benefit of Company Pension Plan participants, such amount to be determined pursuant to Schedule 7.6.2 below; provided, however, that the amount of cash transferred by Seller pursuant to this clause (ii) shall in no event be less than the amount required to be transferred under Section 414(l) of the Code.

Pension Calculations. The “Pension Liability” with respect to the Company Pension Plan Participants means the Accumulated Benefit Obligation to the Company Pension Plan Participants immediately prior to the Closing on the Closing Date under the Seller Pension Plan, determined in accordance with the assumptions and methodologies set forth on Schedule 7.6.2, plus interest accrued thereon at the Seller Pension Plan’s actuarial rate per annum (which shall be the interest rate specified in Schedule 7.6.2) from Closing to the actual date of transfer and decreased by the amount of any benefit payments to Company Pension Plan Participants from the Seller Pension Plan after the Closing Date but before the date of transfer.

Indemnification for Plan Liabilities. From and after the date of the transfer of the assets referred to in Sections 7.5 and 7.6, Buyer shall indemnify and hold Seller, the Seller Savings Plan and the Seller Pension Plan harmless for any loss that Seller or said plans may incur in respect of any obligation or liability transferred under Sections 7.5 or 7.6 to the applicable plans of Buyer designated under such Sections.

Service Credit. For purposes of vesting, benefit accrual, benefit calculation, participation, eligibility (including for optional forms of benefits or early retirement or disability retirement under the Buyer Pension Plan), and matching contribution benefits, if any, Buyer shall, with respect to each benefit required to be provided under the terms of this Article VII, credit each Company Employee with all service credited to the Company Employee under Seller’s corresponding plan, policy, program, or arrangement applicable to such Company Employee as of the Closing Date.

Except as provided in this Article VII, effective as of the Closing Date, Buyer or the Company shall make enrollment available to all Company Employees and their eligible dependents without any waiting period in a Buyer plan or plans providing medical and dental benefits (the “Buyer Medical Plans”), to the extent such individuals were eligible for coverage under the Seller Medical Plans, as contemplated by Section 7.1. Such Buyer Medical Plans shall waive any restrictions and limitations for pre-existing conditions for all Company Employees and shall give credit to each Company Employee for any deductibles and out-of-pocket expenses paid during the current plan year by such Company Employee under Seller’s applicable medical and dental Plans (hereinafter collectively referred to as the “Seller Medical Plans”).

Buyer shall be responsible for medical and dental expenses covered under the terms of the Buyer Medical Plans incurred on or after the Closing Date by a Company Employee and/or his covered dependents who are enrolled in the Buyer Medical Plans. Seller shall be responsible only for medical and dental expenses covered under the terms of the Seller Medical Plans incurred prior to the Closing Date by a Company Employee and/or his covered dependents.

Buyer, at no expense to Seller, shall provide the benefits, if any, required from and after the Closing Date pursuant to COBRA for any Company Employee who is or becomes entitled to such continuation medical coverage from Seller or Buyer on or after the Closing Date, and Seller shall be responsible for any benefits required pursuant to COBRA prior to the Closing Date.

At the Closing Date, the Company shall assume or retain sole liability for all obligations with respect to post-retirement medical and other welfare benefits for all Company Employees and all Former Employees of the Company. The liabilities with

respect to such post-retirement benefits shall be determined in accordance with the applicable methodology and assumptions set forth in Schedule 7.6.2.

Wage Reporting. The Parties acknowledge that, for federal income tax wage reporting purposes, Buyer qualifies as a successor employer with respect to the Company Employees. In connection with the foregoing, the Parties agree to follow the “Alternative Procedures” set forth in Section 5 of Revenue Procedure 96-60, 1996-2-C.B.399. In connection with the application of the “Alternative Procedures,” (i) Seller and Buyer each shall report on a predecessor-successor basis as set forth in such Revenue Procedure, (ii) Seller shall be relieved from furnishing Forms W-2 to the Company Employees, and (iii) Buyer shall assume the obligations of Seller to furnish such Forms W-2 to such employees for the full calendar year in which the Closing occurs.

Access After Closing. Buyer will permit Seller and its representatives reasonable access on reasonable notice during normal business hours, for a period of three (3) years following the Closing Date and for such longer period as may be required in connection with any pending or threatened judicial or administrative proceeding with respect to which Seller is indemnifying the Buyer Indemnified Parties pursuant to this Agreement, to the books and records of the Company, including the right to make copies thereof, and to personnel (for reasonable inquiry and testimony) in compliance with Section 6(a) of the Release of Liability. Notwithstanding the foregoing, Buyer will permit Seller reasonable access after the Closing Date until the date that is six (6) months after the expiration of any applicable statutes of limitations (including extensions thereof) with respect to books and records relating to liabilities for Taxes and Tax Returns of the Company with respect to which Seller is indemnifying the Company pursuant to this Agreement. Similarly, Seller will permit Buyer, the Company and their representatives reasonable access on reasonable notice during normal business hours, for a period of three (3) years following the Closing Date and for such longer period as may be required in connection with any pending or threatened judicial or administrative proceeding, to the books and records of Seller and its Subsidiaries that are relevant to such proceedings with respect to which Buyer is indemnifying the Seller Indemnified Parties pursuant to this Agreement, including the right to make copies thereof, and to personnel (for reasonable inquiry and testimony) in compliance with Section 6(a) of the Release of Liability. Notwithstanding the foregoing, Seller will permit Buyer and the Company reasonable access after the Closing Date until the date that is six (6) months after the expiration of any applicable statutes of limitations (including extensions thereof) with respect to books and records relating to liabilities for Taxes

and Tax Returns of the Company. Seller and Buyer shall preserve all information, records or documents in their respective possessions relating to liabilities for Taxes with respect to the Company for taxable years or portions thereof ending on or before the Closing Date until six (6) months after the expiration of any applicable statute of limitations (including extensions thereof) with respect to the assessment of such Taxes. All information so obtained shall be kept confidential by Buyer and Seller pursuant to the terms and conditions of the Release. As soon as practicable following the Closing Date, at Seller’s sole cost and expense, Buyer shall arrange for the delivery to Seller of the existing records and documents in the Company’s possession relating to Seller’s and its Subsidiaries’ (other than the Company’s) business and affairs, including, without limitation, files and records related to SEECO, Inc. and Southwestern Energy Production Company. In the event Buyer becomes aware (after the Closing) of Buyer’s possession of documents or records related to Seller's or its Subsidiaries’ (other than the Company’s) business and affairs before the Closing Date, Buyer will continue to comply with the foregoing. Similarly, as soon as practicable following the Closing Date, Seller shall arrange for the delivery to Buyer of the existing records and documents in the possession of Seller or any of its Subsidiaries relating solely to the Company’s business and affairs. In the event Seller becomes aware (after the Closing) of Seller’s possession of documents or records related to the Company’s business and affairs before the Closing Date, Seller will continue to comply with the foregoing. For seven (7) years after the Closing Date (or such longer period as may be required by applicable Law), Buyer shall have reasonable access to any other records relating to the Company Employees or Former Employees of the Company or the disclosure of which is required by Law or legal or regulatory process or subpoena, in the possession of Seller or any of its Subsidiaries to the extent that such access may reasonably be required in connection with the Company Employees or Former Employees of the Company, or other matters relating to or affected by the operation of the natural gas distribution business of the Company. The guidelines set forth in Schedule A of the Transition Services Agreement shall supplement this obligation to deliver.

Further Assurances. At any time and from time to time after the Closing Date, Seller shall, at the request of Buyer, and Buyer shall, at the request of Seller, execute and deliver any further instruments or documents and take all such further action as the other Party may reasonably request in order to consummate and make effective the sale of the Shares pursuant to this Agreement or to fulfill any other of such Party’s obligations hereunder.

Confidentiality. The terms of the Confidentiality Agreements are hereby incorporated herein by reference and shall continue in full force and effect; provided, however, that notwithstanding the foregoing, on the Closing Date the Confidentiality Agreements shall terminate and the parties thereto shall be released from all obligations thereunder.

Schedules. Unless the context otherwise requires, all capitalized terms used in the Schedules shall have the respective meanings assigned in this Agreement. No reference to or disclosure of any item or other matter in the Schedules shall be construed as an admission or indication that such item or other matter is material or that such item or other matter is required to be referred to or disclosed in the Schedules. No disclosure in the Schedules relating to any possible breach or violation of any agreement or Law shall be construed as an admission or indication that any such breach or violation exists or has actually occurred. Each disclosure in the Schedules referred to in Article III or IV shall be deemed to qualify all representations and warranties of the Parties notwithstanding the lack of a specific cross-reference to the extent the applicability of such disclosure to such other Schedule is readily apparent on its face.

Pre-Closing Tax Period Returns. With respect to any Tax Return relating to income taxes covering a Pre-Closing Tax Period with respect to the Company, Seller shall cause such Tax Return to be prepared and to be filed timely with the appropriate Governmental Authority, and Seller shall pay to the appropriate Governmental Authority, on or prior to the due date for any such Tax Return, all amounts which are shown as due on such Tax Return. Seller shall be entitled to any refund for Taxes (and related interest) for any period covered by any such Tax Return.

Straddle Returns. With respect to any Tax Return covering a Tax period beginning on or before the Closing Date and ending after the Closing Date (a “Straddle Period Return”) with respect to the Company, Buyer shall cause such Tax Return to be prepared, shall cause to be included in such Tax Return all Tax Items required to be included therein and shall furnish a copy of such Tax Return to Seller. Seller shall provide Buyer with the information necessary to prepare all such Tax Returns. Seller shall pay to Buyer at least five (5) days prior to the due date for the filing of any Straddle Period Return an amount equal to the portion of the Taxes shown on such return which relates to the portion of such Tax period ending on the Closing Date (a “Pre-Closing Straddle Period”). For purposes of this Section 8.5.2, in the case of any Taxes, other than corporate income taxes, that are imposed on a periodic basis and are payable with respect to a taxable period that includes (but does not end on) the Closing Date, the portion of such Tax which relates to the portion of such taxable period ending on the Closing Date shall (i) in the case of any Taxes other than Taxes based upon or related to income, receipts, sales or payroll, be deemed to be the amount of such Tax for the entire Tax period multiplied by a fraction the numerator of which is the number of days in the taxable period ending on the Closing Date and the denominator of which is the number of days in the entire taxable period, and (ii) in the case of any Tax, other than corporate income tax, based upon or related to income, receipts, sales or payroll, be deemed equal to the amount which would be payable if the relevant Tax period ended on the Closing Date. Any franchise or similar Taxes shall be allocated to the period during which the

income operations, assets or capital comprising the base of such Tax is measured, regardless of whether the right to do business for another period is obtained by the payment of such franchise Tax. For purposes of corporate income Tax Returns filed with the IRS and the State of Arkansas, such Tax Returns shall be filed in accordance with the requirements of Internal Revenue Service Regulations §1.1502-76(b), which require that Seller include all items of income, gain, deduction, loss and credit for the portion of the tax return year for which the Company is a member of Seller's consolidated tax return group. The Company shall remain a member of Seller's consolidated tax return group until the Closing Date and Seller shall cause income tax returns to be filed which include all applicable return items that occur prior to the Closing Date. For the Tax Return period following the Closing Date, all items of income, gain, deduction, loss and credit shall be reported by Buyer in its consolidated group return or in a separate return filed by the Company as set forth in the Internal Revenue Service Regulations §1.1502-76(b). Buyer shall cause income tax returns to be filed which include all applicable return items that occur subsequent to the Closing Date. Income tax payments will be the responsibility of the party required to file the returns.

Post-Closing Tax Period Returns. Buyer shall prepare or cause to be prepared and file or cause to be filed all Tax Returns for the Company for all Tax years beginning after the Closing Date.

Consistency. Any Tax Return to be prepared pursuant to the provisions of Section 8.5.2 or 8.5.3 shall be prepared in a manner consistent with practices followed in prior years with respect to similar Tax Returns, except for changes required by changes in law or fact. Buyer shall not (or after the Closing, shall not cause or permit the Company to) amend, refile or otherwise modify (or grant an extension of any statute of limitation with respect to) any Tax Return relating in whole or in part to the Company (i) with respect to any Pre-Closing Tax Period, or (ii) with respect to any Straddle Period Return without the prior written consent of Seller, which consent shall not be unreasonably withheld.

Access to Tax Records. Seller shall grant to Buyer (or its designees) access at all reasonable times to all of the information, books and records relating to the Company within the possession of Seller or any member of the Seller Group (including workpapers and correspondence with taxing authorities), and shall afford Buyer (or its designees) the right (at Buyer’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Buyer (or its designees) to prepare Tax Returns and to conduct negotiations with Governmental Authorities. Buyer shall grant or cause the Company to grant to Seller (or its designees) access at all reasonable times to all of the information, books and records relating to the Company within the possession of Buyer or the Company (including workpapers and correspondence with taxing authorities), and shall afford Seller (or its designees) the right (at Seller’s expense) to take extracts therefrom and to make copies thereof, to the extent reasonably necessary to permit Seller (or its designees) to prepare Tax Returns and to conduct negotiations with taxing authorities.

Transfer Taxes. Buyer shall be responsible for the payment of all state and local transfer, sales, use or other similar Taxes resulting from the transactions contemplated by this Agreement.

Indemnification for Taxes. From and after the Closing Date, Seller shall protect, defend, indemnify and hold harmless Buyer and the Company from any and all (i) Losses resulting from a breach of the representations and warranties in Section 3.11 (and the certifications in Seller’s Closing Certificate insofar as relating to said Section 3.11) and (ii) Taxes imposed on Buyer or the Company (a) for any Tax period beginning on or after the Beginning Tax Date and ending on or before the Closing Date (except for Taxes resulting from any transaction not in the ordinary course of business occurring on the Closing Date after the Closing), (b) with respect to any Pre-Closing Straddle Period or (c) resulting by reason of the liability of the Company for Taxes pursuant to Treas. Reg. § 1.1502-6 or any analogous state, local or a foreign law or regulation for periods beginning on or before the Closing Date; provided, however, that Seller’s liability under this Section 8.5 shall be reduced with respect to any item to the extent that the amount of such item is reflected as a current liability in Net Working Capital for purposes of Section 2.2.2. Buyer shall protect, defend, indemnify and hold harmless Seller and each member of the Seller Group from any and all other Taxes imposed on the Company. For purposes of this Section 8.5.7, in determining whether there has been a breach of the representations and warranties in Section 3.11 (and the certifications in Seller’s Closing Certificate insofar as relating to said Section 3.11), the terms “Material Adverse Effect,” “material,” “materiality” and words of similar import used therein shall be disregarded.

Tax Proceedings. In the case of any audit, examination or other proceeding (“Tax Proceeding”) with respect to Taxes for which Seller would be liable pursuant to this Agreement, Buyer shall promptly inform Seller, and shall afford Seller, at its expense, the opportunity to control the conduct of such Tax Proceedings. Seller shall have the right to initiate any claim for refund, file any amended Tax Return or take any other action which it deems appropriate with respect to such Taxes; provided, however, that such action does not adversely affect Buyer or the Company for any Tax year beginning after the Closing Date. Any Tax Proceeding with respect to Taxes for a period which includes but does not end on the Closing Date shall be controlled jointly by Seller and Buyer.

Tax Sharing Agreements. On or before the Closing Date, (i) all tax sharing agreements and arrangements (other than those reflected in this Section 8.5) with respect to or involving the Company shall be terminated and, after the Closing Date, the Company shall not be bound thereby or have any liability or obligations thereunder, (ii) all intercompany obligations or payables between the Company and Seller or any Affiliate of Seller relating to Taxes (other than those reflected in this Section 8.5) shall have been eliminated and the Company shall have no obligation to Seller or any Affiliate of Seller with respect to Taxes other than those reflected in this Section 8.5.

Tax Refunds. Any refunds or credits of Taxes that were paid in respect of a Tax year or Tax period of the Company for a Pre-Closing Tax Period shall be for the account of Seller (except to the extent appearing as an asset on the Closing Statement),

and any refund or credits of Taxes that were paid in respect of a Tax year or Tax period of the Company beginning on or after the Closing Date shall be for the account of Buyer. Buyer shall pay the amount of any such refunds or credits to the other Party within fifteen (15) days after receipt thereof. The preceding sentences shall not apply to any refunds or credits to the extent such refunds or credits are an asset on the Closing Statement, in each case, all of which refunds or credits shall be for the account of Buyer.

FIRPTA Certificate. At Closing Seller shall provide to Buyer a "Certificate of Non-Foreign Status" as prescribed in Treas. Reg. Section 1.1445 -2.

Evidence of the cancellations referred to in this Section 8.6 (in form and substance acceptable to the Buyer) shall be provided to Buyer at the Closing.

Litigation and Other Proceedings. Buyer and Seller shall use commercially reasonable efforts to cooperate with the other after the Closing Date in connection with any litigation or other proceedings relating to the Company or its business or assets. Without limiting the generality of the foregoing, in connection with such litigation or other proceedings, the Parties will comply with Section 8.1 hereof.

Buyer and Seller agree that some assets (including equipment) connected to the Company’s gathering system are not assets of the Company. Buyer and Seller hereby agree that, as of the Closing Date, equipment located from the wellhead to the inlet flange of the Company’s measurement meter shall be owned by Seller and title to such assets shall be in the name of Seller, and all other equipment located from the Company’s measurement meter to the Company’s gathering system shall be owned by the Company and title to such assets shall be in the name of the Company. Buyer and Seller shall take and do all commercially reasonable actions to ensure that title to such assets are in the name of the Company or Seller, as applicable, in accordance with this Section 8.8(a).

Buyer and Seller agree that, on or prior to the Closing Date, the Company shall transfer and convey the Office Building to Seller as a distribution in respect of the Shares (the “Office Building Conveyance”). The deed effecting such transfer and conveyance shall be in form and substance reasonably acceptable to Buyer and Seller but shall in any event expressly disclaim all express and implied representations and warranties on the part of the Company (including warranties of title and condition) and Seller shall pursuant to such document (i) expressly assume all liabilities and obligations, whether known or unknown, implied or express, relating to the Office Building and take

the Office Building “as is, where is” subject to any and all Encumbrances thereon and (ii) indemnify the Company and its successors and assigns from and against any and all Losses to which the Company or any of its successors or assigns becomes subject or which the Company or any of its successors or assigns suffers or incurs arising out of the ownership or operation of the Office Building prior to or after the Closing. At the Closing, immediately following the transfer of the Shares to Buyer, Seller and the Company shall enter into a lease with respect to the premises of the Office Building in the form set forth in Exhibit C hereto (the “Building Lease”). Seller shall pay (without right of reimbursement from the Company or Buyer) all costs, fees, taxes and expenses in connection with the Office Building Conveyance including transfer and recordation fees and taxes. The Parties acknowledge and agree that the covenants and agreements contained in this Section 8.8(b) shall not supersede the conditions to Closing set forth in Sections 9.8 and 10.8 or limit the requirement that any such condition be satisfied or waived as set forth therein as a condition to the obligations of the applicable Party to consummate the transactions contemplated at the Closing. For the avoidance of doubt, neither the Seller Filings nor Buyer Filings shall include any offer or otherwise require any Person to provide any consideration or to incur any current or future liability (other than the obligations of the parties as set forth in the Building Lease) or to agree to a net loss of benefit for the Company in order to cause or permit the distribution of the Office Building as contemplated by this Agreement.

Buyer agrees that it is the express intention of Buyer and Seller that any right of first refusal that may be held by the Company with respect to the Stockton Storage Facility owned by a Subsidiary of Seller be terminated as a part of the transactions contemplated hereby and the reverter contained in the deed to the real property related thereto be relinquished and that the applicable APSC application(s) to be filed pursuant to Sections 5.1 and 6.1 provide for the modification by the APSC of the Stipulation and Agreement approved in Order #52 under Docket 92-028-U (including any amendments of such Stipulation and Agreement) to eliminate any requirement for the Company to retain any such right of first refusal and to cause title to the Stockton Storage Facility and the related real property to be held by such Seller’s Subsidiary free and clear of all Encumbrances arising pursuant to such Stipulation and Agreement and amendments (“Stockton Encumbrances”). Further, at and following the Closing, Buyer agrees to take and do, and to cause the Company to take and do (subject to and in accordance with the decisions of the APSC), all commercially reasonable actions necessary (including the execution of such other documents as Seller may reasonably request) to remove any Encumbrances arising by, through or under the Company from the title to the Stockton Storage Facility and the related real property including, if requested by Seller, seeking the consent or approval of any third party; provided, however, that neither Buyer nor the Company shall be required to provide any consideration to any Person or incur any current or future liability or loss of benefit to cause or permit the removal of any Encumbrance. The Parties acknowledge and agree that the covenants and agreements contained in this Section 8.8(c) shall not affect or supersede the condition to Closing set forth in Section 10.4.

dated as of and effective as of the Closing Date in the form set forth in Exhibit D hereto (the “Release of Liability”), which in no event shall affect the existing agreements (other than the Terminated Arrangements (as defined in Schedule 8.9) and the Intercompany Note) by and among the Company, Seller and Seller’s Affiliates, which agreements are described in Schedule 8.9 hereof.

Charitable Contributions, Etc. Following the Closing Date, Buyer shall cause the Company to honor and pay all commitments of the Company with respect to charitable contributions and local community support that are set forth on Schedule 8.10 hereof.

Novation of Hedging Agreements. Buyer shall have the right, but at its sole cost and expense, at any time prior to the Closing Date to require the novation (pursuant to a novation agreement in form and substance reasonably satisfactory to Buyer) of any or all of the Hedging Agreements to the Company or any other designee of Buyer effective as of the Closing Date (the “Novation of Hedging Agreements”) and Seller shall novate the designated Hedging Agreements (or cause the applicable Affiliate of Seller to so novate) effective as of the Closing Date and deliver a duly executed original of each such Novation of Hedging Agreement to Buyer at the Closing. The Company shall have the right to enter into Hedging Agreements in the ordinary course of business consistent with past practice but prior to entering into any such Hedging Agreement, Seller shall use its commercially reasonable efforts to provide Buyer with a reasonable opportunity to review such Hedging Agreement (and credit support requirements relating thereto) and consult with Seller with respect thereto. Any Hedging Agreement entered into after the date hereof and prior to Closing for the Company’s benefit shall be entered into directly by the Company and not through Seller or any other Person. Subject to Section 5.2, in no event shall Seller be obligated to enter into, or to cause the Company to enter into, any Hedging Agreements.

Transition Trademark License. Seller, Buyer and the Company shall enter into, execute and deliver a transition trademark license agreement to be dated as of and effective as of the Closing Date, in the form attached to this Agreement as Exhibit H whereby Seller grants to Buyer and the Company the right to use the business names, brand names, trade names, trademarks, services marks, logos and domain names or any portion thereof of Seller or its Affiliates that are not assigned to Buyer on the Closing Date but that on or before the Closing Date were used in connection with or on the Company’s equipment, goods, services, inventory,

signage, publications, websites, marks, names, logos, supplies, software, pipelines, or other assets, all as more particularly set forth in Exhibit H (the “Transition Trademark License Agreement”)

Abstracts. Within seventy-five (75) days after the date hereof, Seller shall cause to be prepared by a title abstractor reasonably acceptable to Buyer and delivered to Buyer abstracts of title for the Owned Properties (other than office and warehouse space) (the “Abstracts”) showing, in customary detail, the state of title to such assets, including the legal description and any other identification of such assets and the instruments creating or evidencing such assets and the Encumbrances to which such assets are subject and the instruments otherwise reflected in the Abstracts (all the instruments referred to in this sentence hereinafter referred to as the “Instruments”). If, within twenty (20) Business Days following Buyer’s receipt of the Abstracts (and copies of the Instruments) from Seller and a letter from Seller listing all of the Abstracts delivered to Buyer in accordance with this Section 8.15 and stating that the listed Abstracts constitute all of the Abstracts for purposes of Section 8.15, Buyer does not inform Seller that, in Buyer’s sole good faith reasonable discretion, the state of title reflected in such Abstracts are, in the aggregate, not satisfactory to Buyer, then the Abstracts shall be deemed satisfactory to Buyer for the purposes of this Agreement. If the state of title reflected in the Abstracts is not satisfactory to Buyer in Buyer’s sole good faith reasonable discretion, then Buyer shall notify Seller in writing prior to expiration of such twenty (20) Business Day period and specifically identify the issues that exist with respect to the state of the title that caused it to be unsatisfactory to Buyer and the steps that Buyer requires to be taken to remedy such issues (“Buyer Objection Notice”). Seller shall have the right (but not the obligation) at Seller’s sole cost and expense (the “Seller Option”) to take the steps required by Buyer to remedy the title issues. If Seller (i) notifies Buyer in writing that it is not exercising the Seller Option, or (ii) fails to notify Buyer within ten (10) Business Days after Seller’s receipt of the Buyer Objection Notice (the “Seller Notice Period”) that Seller has elected to exercise the Seller Option, then Buyer shall have the right to terminate this Agreement pursuant to Section 11.1(d). If Seller elects to exercise the Seller Option, Seller shall use commercially reasonable efforts to remedy the title issues and shall keep Buyer regularly apprised of the status of the title curative work.

Transition Services Agreement. Seller shall consider in good faith such modifications to the form of Transition Services Agreement attached as Exhibit B as Buyer may propose, it being recognized that Buyer has not completed its evaluation of all transition services it may desire that Seller provide. Seller shall not unreasonably withhold its consent to Buyer’s request to add any services to the Transition Services Agreement so long as such services are consistent with Seller’s past practices, in terms of quantity and quality, and the fees for such additional services shall not exceed the amounts of Seller's historical allocation of costs (including overhead) to the Company for providing such services.

The obligations of Buyer under this Agreement to purchase the Shares and to consummate the other transactions at the Closing contemplated hereby shall be subject to the satisfaction (or waiver by Buyer in writing in its sole discretion) on or prior to the Closing Date of all of the following conditions:

Seller shall have complied in all material respects with its agreements and covenants contained herein to be performed on or prior to the Closing Date, and all the representations and warranties of Seller contained herein shall be true and correct in all material respects on and as of the Closing Date (other than those representations and warranties which are qualified by “Material Adverse Effect”, “material”, “materiality” or similar words, which shall be true and correct in all respects on and as of the Closing Date) with the same effect as though made on and as of the Closing Date, except (i) to the extent that such representations and warranties were made as of a specified date, and as to such representations and warranties the same shall continue on the Closing Date to have been true and correct in all material respects as of the specified date (other than those representations and warranties which are qualified by “Material Adverse Effect”, “material”, “materiality” or similar words, which shall be true and correct in respect as of the specified date) and (ii) Seller may update any Schedule referred to in Article III hereto at any time prior to the Closing Date to reflect changes after the date hereof resulting from the conduct of the Company’s business in the ordinary course consistent with past practice, if such updated Schedule does not reflect any matter that could, individually or in the aggregate, adversely affect Buyer or the Company in any material respect (but no such matter included in any updated Schedule shall limit, modify or otherwise affect the remedies available hereunder to Buyer, including any right to indemnification or the representations or warranties of, or the conditions to the obligation of, the Parties under or with respect to this Agreement); provided, however, Buyer shall have no right to indemnification under Section 12.1(a) insofar as relating to Section 3.6 with respect to the Owned Properties (or the certifications in Seller’s Closing Certificate relating to Section 3.6 with respect to the Owned Properties) with respect to any matter reflected in the Abstracts delivered to Buyer within seventy-five (75) days after the date hereof pursuant to Section 8.15 and Seller shall not be in breach of any representation or warranty set forth in this Agreement insofar as relating to Section 3.6 (or the certifications in Seller’s Closing Certificate relating to Section 3.6 with respect to the Owned Properties) as a result of any matter set forth in said Abstracts. Buyer shall have received a certificate of Seller, dated as of the Closing Date and signed by an officer of Seller, certifying as to the fulfillment of the conditions set forth in this Section 9.1 (“Seller’s Closing Certificate”).

Legal Proceedings. No preliminary or permanent injunction or other order issued by a Governmental Authority, and no statute, rule, regulation or executive order promulgated or enacted by a Governmental Authority or arbitral body, which restrains, enjoins, prohibits or otherwise makes illegal the consummation of the transactions contemplated hereby shall be in effect and there shall not be any action, suit, proceeding or investigation pending or threatened seeking to restrain, enjoin, prohibit or otherwise make illegal the consummation of the transactions contemplated by this Agreement. In addition, there shall not be any action, suit, proceeding or investigation, instituted or commenced by, or settled with, any Governmental Authority that would, or would be reasonably likely to, result in the imposition of either (i) material limitations on the ability of Buyer to exercise customary rights of ownership in the business of the Company; (ii) criminal sanctions on Buyer or any of its Affiliates arising from (A) the transactions contemplated by this Agreement, (B) actions of the Company; or (C) actions of Seller or its Affiliates and imposed on Buyer or its Affiliates as a result of entering into this Agreement or the consummation of the transactions contemplated therein, (iii) criminal sanctions on the Company; or (iv) any material penalties, fines or orders of restitution on Buyer (taking

into account the consummation of the transactions contemplated by this Agreement) or on the Company.

All consents, approvals or orders of each Governmental Authority referred to in Schedules 3.10 or 4.4 (other than item 4 (environmental permits) on such Schedules) hereto as well as all consents, approvals and orders of the APSC, the granting of which are necessary to consummate the transactions contemplated hereby, shall have been obtained with terms that are satisfactory to Buyer, in Buyer’s sole good faith and reasonable discretion; provided, however, that any consent, approval or order shall be deemed satisfactory to Buyer for purposes of this Agreement to the extent that the terms and conditions of such consent, approval or order are consistent with and are not less favorable to Buyer in any material respect than those terms and conditions contained in consents, approvals or orders obtained in connection with the acquisition of the companies or assets that constitute the Buyer Group.

The consents and approvals of third parties (other than any Governmental Authority) identified on Schedule 9.3 shall have been obtained; provided, however, that if any such consent or approval is not obtained, this condition will be deemed satisfied if Buyer and Seller enter into arrangements reasonably satisfactory to Buyer and Seller that result in the Company being in the same economic position as though such consent or approval had been obtained.

No Material Adverse Effect. Since the date of this Agreement, there shall not have occurred any events that, individually or in the aggregate, have had or could reasonably be expected to have a Material Adverse Effect.

Termination. This Agreement may be terminated and the transactions contemplated hereby may be abandoned at any time prior to the Closing:

By either Seller or Buyer, if any Governmental Authority with jurisdiction over such matters shall have issued an order restraining, enjoining, or otherwise prohibiting the sale of the Shares hereunder and such order shall have become final and unappealable; provided, however, that the right to terminate this Agreement under this Section 11.1(b) shall not be available to a Party if such order was primarily due to the failure of such Party to perform any of its obligations under this Agreement;

By either Buyer or Seller if the other Party breaches or fails to comply in any material respect with any of its representations, warranties, covenants or agreements in this Agreement; provided, however, that the terminating Party must give the defaulting Party at least twenty (20) days' prior written notice of such failure and the failure is not, or cannot be, cured before expiration of such period;

By Buyer, within ten (10) Business Days after the earlier of (i) the date upon which Seller notifies Buyer that it will not be exercising the Seller Option, or (ii) the expiration of the Seller Notice Period; or

By either Buyer or Seller, if the Closing shall have not occurred on or before July 1, 2008; provided, however, that the right to terminate this Agreement under this Section 11.1(e) shall not be available to any Party whose failure to fulfill any

obligation under this Agreement shall have been the cause of, or resulted in, the failure of the Closing to occur on or before such date.

Effect of Termination. In the event of termination of this Agreement as provided in Section 11.1, this Agreement shall forthwith become void; provided, however, that such termination shall not relieve any Party of its obligations under Section 8.3, this Section 11.2, Section 13.7 and Section 13.13, nor relieve any Party from liability for any breach of this Agreement and Article I, Sections 8.3, 11.1, 11.2 and Article XIII shall survive termination of this Agreement. Upon any termination of this Agreement, each Party will return all documents, work papers and other material of the other Party relating to the transactions contemplated hereby and all copies of such materials, whether so obtained before or after the execution hereof, to the Party furnishing the same, provided that each Party may retain one copy of all of the foregoing.

Indemnification by Seller. Subject to Sections 12.3 and 12.4, from and after the Closing, Seller shall protect, defend, indemnify and hold harmless Buyer and its Affiliates and Buyer’s and such Affiliates’ respective directors, officers, partners, owners and employees (each such Person, a “Buyer Indemnified Party” and, collectively, the “Buyer Indemnified Parties”) from and against any and all Losses to which any Buyer Indemnified Party becomes subject or which any Buyer Indemnified Party suffers or incurs, insofar as such Losses arise out of or result from (a) any breach by Seller of any of its representations or warranties made in this Agreement or any breach of any certification made in Seller’s Closing Certificate, (b) any breach of any of the covenants or agreements of Seller contained in this Agreement, (c) any current or former employee of Seller or any of Seller’s Affiliates in connection with their employment or termination of employment on or prior to the Closing (other than liabilities assumed by Buyer pursuant to Section 7.9.4, Section 7.7 or the Assumed Plans) and/or (d) the Gas Cost Compliance Audit including any Losses attributable to disallowance of costs (or settlement of any dispute with the APSC concerning the prudence of costs incurred by the Company); provided, however, that when determining whether representations or warranties or certifications of Seller set forth in this Agreement or in Seller’s Closing Certificate have been breached for purposes of determining the indemnification obligations of Seller under this Agreement, (x) the terms “Material Adverse Effect”, “material,” “materiality” or words of similar import as used therein shall be disregarded (other than (i) the reference to “material” and “materiality” in Section 3.12 (Financial Statements), (ii) the reference to “material” in Section 3.17 (Insurance), (iii) the references to “material,” “non-material” and “Material Adverse Effect” in Section 3.18) (No Undisclosed Liabilities; No Material Adverse Effect), and (iv) the references to “material” in Section 3.22 (Books and Accounts), in which cases effect shall be given to such qualifiers included therein), and (y) the term “Knowledge of Seller” in (I) the last sentence of Section 3.5 and (II) the penultimate sentence of Section 3.6 shall be disregarded. As used herein, “Losses” means any losses, liabilities, claims, damages or obligations (including whether direct or indirect, known, unknown, absolute or contingent, accrued or unaccrued or liquidated or unliquidated) and whether in contract, tort, strict liability or otherwise, and including all reasonable costs and expenses relating thereto (including all reasonable fees, disbursements and expenses of legal counsel, experts, engineers and consultants and costs of investigation), whether or not involving a third party claim; provided, however, that Losses shall not include (i) any consequential,

special, multiple, punitive or exemplary damages, except to the extent resulting from third party claims or (ii) any amount taken into account (without duplication) in determining (A) the Closing Purchase Price pursuant to Section 2.2.1 as a result of taking such Losses into account in determining the Estimated Net Working Capital or (B) the Purchase Price pursuant to Section 2.2.2 as a result of taking such Losses into account in determining the Closing Net Working Capital. Notwithstanding the forgoing, Section 8.5 shall be the exclusive remedy with respect to matters related to Taxes and the representations and warranties in Section 3.11 (and the certifications in Seller’s Closing Certificate insofar as relating to said Section 3.11) and this Section 12.1 shall not apply to such matters.

Indemnification by Buyer. Subject to Sections 12.3 and 12.4, from and after the Closing, Buyer shall protect, defend, indemnify and hold harmless Seller, its Affiliates and their respective directors, officers, partners, owners and employees (each such Person, a “Seller Indemnified Party” and, collectively, the “Seller Indemnified Parties”) from and against any and all Losses to which any Seller Indemnified Party becomes subject or which any Seller Indemnified Party suffers or incurs, insofar as such Losses arise out of or result from (a) any breach by Buyer of any of its representations or warranties made in this Agreement or any breach of any certification made in the Buyer’s Closing Certificate, or (b) any breach of any of the covenants or agreements of Buyer contained in this Agreement.

Time Limitations and Survival. The representations and warranties of the Parties under this Agreement and the certifications contained in Seller’s Closing Certificate and the Buyer’s Closing Certificate shall survive the Closing and any investigation by the Parties. Any claim for indemnification by any Buyer Indemnified Party or Seller Indemnified Party pursuant to Section 12.1 or Section 12.2 must be made by written notice given within twelve (12) months after the Closing Date, except with respect to claims for indemnification relating (A) to a breach of any of the covenants or agreements that are performable after the Closing as contained in Article VII and/or any of Sections 2.2.2, 5.1, 5.9, 5.10, 5.11, 6.2, 8.1, 8.2, 8.3, 8.5, 8.7, 8.8, 8.10, 12.4, 12.5, 13.11, 13.12 and 13.13 (collectively, the “Post-Closing Covenants”), (B) the provisions of Section 12.1(b) and 12.2(b) solely as they relate to the Post-Closing Covenants, (C) Section 12.1(c) and (D) (unless terminated pursuant to Section 10.12) Section 12.1(d); provided, however, that (a) any claim for indemnification by any Buyer Indemnified Party with respect to any breach of any of the representations and warranties set forth in Sections 3.2 (Authorization and Validity of Agreement; Title to Shares), 3.3(i) (No Contravention) and/or 3.11 (Tax Matters) (and the certifications in Seller’s Closing Certificate relating to said Sections 3.2, 3.3(i) and/or 3.11) and (b) any claims pursuant to Section 8.5.7, may be made by written notice within sixty (60) days after the expiration of the applicable statute of limitation period. Notwithstanding anything to the contrary, in the event that written notice of a breach of a representation or warranty (or a breach of a covenant or agreement that by its nature is performable prior to or at the Closing) contained herein or in Seller’s Closing Certificate or Buyer’s Closing Certificate that gives rise to a claim for indemnification pursuant to Section 12.1 or 12.2 has, prior to the expiration of the applicable survival period for such representation or warranty (or covenant or agreement), been given to the Party against whom such indemnity claim may

be brought, the fact that the applicable survival period expires prior to the resolution of such indemnity claim shall not preclude any Buyer Indemnified Party or Seller Indemnified Party, as the case may be, from pursuing such indemnity claim to its final resolution and obtaining indemnification from Seller or Buyer, as applicable, hereunder.

Seller will have no obligation to indemnify Buyer for any Losses pursuant to Section 12.1, except to the extent that such Losses, taken together, exceed $1,000,000 (the “Seller Deductible”), and then only to the extent of such excess. In no event shall Seller be liable for Losses pursuant to Section 12.1 of more than 15% of the Purchase Price (as determined pursuant to Section 2.2.2 and without regard to Section 12.4(d)) in the aggregate (the “Seller Cap”). Notwithstanding anything to the contrary, the limitations on Seller’s obligations and liabilities set forth above in this Section 12.3.2(a) shall not apply to (i) Section 12.1(a) insofar as relating to Sections 3.2, 3.3(i) and/or 3.11 or the certifications in Seller’s Closing Certificate relating to said Sections 3.2, 3.3(i) and/or 3.11, (ii) Section 12.1(b) insofar as relating to any willful breach of any of the covenants or agreements of Seller contained in this Agreement that, by their nature, are performable at or prior to the Closing, (iii) Section 12.1(b) insofar as relating to any breach of any of the covenants or agreements of Seller contained in this Agreement that, by their nature, are performable after the Closing or (iv) Section 12.1(c) or 12.1(d) (provided that Section 12.1(d) shall be subject to the Seller Cap). Any amounts paid to any Buyer Indemnified Party relating to clauses (i), (ii), (iii) and/or (iv) of this Section 12.3.2(a) shall not count toward the Seller Deductible or (other than with respect to Section 12.1(d)) the Seller Cap, or otherwise be considered in determining whether the Seller Deductible has been reached or (other than with respect to Section 12.1(d)) the Seller Cap has been exceeded.

Buyer will have no obligation to indemnify Seller for any Losses pursuant to Section 12.2, except to the extent that such Losses, taken together, exceed $1,000,000 (the “Buyer Deductible”), and then only to the extent of such excess. In no event shall Buyer be liable for Losses pursuant to Section 12.2 of more than 15% of the Purchase Price (as determined pursuant to Section 2.2.2 and without regard to Section 12.4(d)) in the aggregate (the “Buyer Cap”). Notwithstanding anything to the contrary, the limitations on Buyer’s obligations and liabilities set forth above in this Section 12.3.2(b) shall not apply to (i) Section 12.2(a) insofar as relating to Sections 4.2 (Authorization and Validity of Agreement) and/or 4.3(i) (No Contravention) or the certifications in the Buyer’s Closing Certificate relating to said Sections 4.2 and/or 4.3(i), (ii) Section 12.2(b) insofar as relating to any willful breach of any of the covenants or agreements of Buyer contained in this Agreement that, by their nature, are performable at or prior to the Closing or (iii) Section 12.2(b) insofar as relating to any breach of any of the covenants or agreements of Buyer contained in this Agreement that, by their nature, are performable after the Closing, including Section 7.7. Any amounts paid to any Seller Indemnified Party relating to clauses (i), (ii) and/or (iii) of this Section 12.3.2(b) shall not count toward the Buyer Deductible or Buyer Cap or otherwise be considered in determining whether the Buyer Deductible or Buyer Cap has been satisfied.

Other Limitations. Any payment by an indemnifying Party shall be reduced by the amount of insurance proceeds recovered from any Person seeking indemnification with respect thereto. If any Indemnified Party may have the right to recover Losses from a third party (that is not an Affiliate of such Indemnified Party) in addition to the indemnifying Party, the Indemnified Party shall assign such right (to the extent assignable) to the indemnifying Party (to the extent of the amount of the payment in respect of the indemnification obligation in question that is actually paid by the indemnifying Party to the Indemnified Party) and shall reasonably cooperate (at the expense of the indemnifying Party) in pursuing any rights against such third party.

Promptly after receipt by any Indemnified Party of notice of the commencement of any action, proceeding or claim in respect of which such Indemnified Party intends to seek indemnification pursuant to Section 12.1 or 12.2, such Indemnified Party shall notify the indemnifying Party in writing; provided, however, that the omission to so notify shall not relieve the indemnifying Party of its indemnification obligations except to the extent the indemnifying Party is materially prejudiced thereby. The indemnifying Party shall by giving notice to the Indemnified Party of its election to assume control of the defense of such action, proceeding or claim within ten (10) days after the Indemnified Party provides notice to the indemnifying Party of the commencement thereof be entitled to assume control of the defense of such action, proceeding or claim with counsel reasonably satisfactory to the Indemnified Party; provided, however, that:

the Indemnified Party shall be entitled to participate in the defense of such action, proceeding or claim and to employ counsel (i) at its own expense to assist in the handling of such action, proceeding or claim, (ii) at the expense of the indemnifying Party if requested by the Indemnified Party to participate therein and (iii) at the expense of the indemnifying Party if in the reasonable opinion of counsel to the Indemnified Party a conflict or potential conflict exists between the Indemnified Party and the indemnifying Party that would make such separate representation advisable;

no indemnifying Party shall consent to the entry of any judgment or enter into any settlement unless such settlement or judgment (A) includes as an unconditional term thereof the giving by each claimant or plaintiff to the Indemnified Party and its Affiliates of a release from all liability in respect of such action, proceeding or claim and (B) does not involve any injunctive or other relief against the Indemnified Party or any of its Affiliates or their businesses or operations;

after providing written notice by the indemnifying Party to the Indemnified Party of its election to assume control of the defense of any such action, proceeding or claim in accordance with the foregoing provisions, the indemnifying Party shall not (except as otherwise expressly set forth herein) be liable to such Indemnified Party hereunder for any legal fees, costs and expenses subsequently incurred by such Indemnified Party in connection with the defense thereof; and

if a firm offer is made to settle any action, claim or proceeding that does not require the consent of the Indemnified Party pursuant to clause (ii) above and the indemnifying Party desires to accept and agree to such offer, it shall notify the Indemnified Party thereof prior to settling such action, claim or proceeding and if the Indemnified Party fails to consent to such firm offer within twenty (20) days after its receive of such notice, the Indemnified Party shall have the right to continue to contest or defend such action, claim or proceeding and, in such event, the maximum liability of the indemnifying Party with respect to such claim, action or proceeding shall be the amount of such settlement offer, plus reasonable costs and expenses paid or incurred by the Indemnified Party up to the date of such notice.

If the indemnifying Party does not assume control of the defense of such action, proceeding or claim in accordance with the foregoing provisions, the Indemnified Party shall have the right to defend such action, proceeding or claim in such manner as it may deem appropriate at the sole cost and expense of the indemnifying Party, and the indemnifying Party will promptly reimburse the Indemnified Party therefor in accordance with this Section 12.4; provided, however, that the Indemnified Party shall not be entitled to consent to the entry of any judgment or enter into any settlement of such action, proceeding or claim for which indemnification is sought without the prior written consent of the indemnifying Party (not to be unreasonably withheld or delayed).

Notwithstanding the provisions of Section 12.4(a), the provisions of Section 8.5.8 shall control the conduct of any Tax Proceeding.

All indemnification payments under this Article XII shall be considered adjustments to the Purchase Price.

Exclusive Rights and Remedies. If the Closing occurs, then the rights and remedies provided in Section 8.5.7 and this Article XII shall constitute the sole and exclusive rights and remedies with respect to the subject matter of this Agreement, and Buyer and Seller each waives all other rights and remedies, including without limitation any arising under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 as amended and any similar state law. Notwithstanding the foregoing, the provisions of Article VIII and this Article XII shall not affect the rights of any Party against any third party (including a third party whose claim against a Party is the basis of a claim for indemnification) and shall not inure to the benefit of any third party; provided, however, that this Section 12.5 is not a limitation on a Party’s rights and obligations under any agreement delivered pursuant to this Agreement.

Entire Agreement. This Agreement (including the Exhibits and Schedules hereto) and the Confidentiality Agreements referred to in Section 8.3 constitute the entire understanding of the Parties with respect to the subject matter hereof and, except as provided in Section 8.3, supersedes all other prior or contemporaneous oral or written statements by any Party with respect thereto.

No waiver of any of the provisions of this Agreement shall be deemed to or shall constitute a waiver of any other provision hereof (whether or not similar). No delay on the part of any Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof.

No Third-Party Beneficiary Rights. Subject to Sections 12.1 and 12.2, this Agreement is not intended to and shall not be construed to give any Person other than the Parties any interest or rights (including, without limitation, any third party beneficiary rights) with respect to or in connection with any agreement or provision contained herein or contemplated hereby.
