Notwithstanding anything in this Section 2.2 to the contrary, Assumed Liabilities shall not include any liabilities, responsibilities or obligations expressly stated to be Retained Liabilities pursuant to Section 2.3.

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

Anything in this Agreement to the contrary notwithstanding, this Agreement shall not constitute an agreement to assign or assume any Contract or any claim or right or any benefit arising thereunder or resulting therefrom if an attempted assignment or assumption thereof, without the Consent of a third party thereto, would constitute a breach thereof. Any transfer or assignment to Buyer by Seller or any of its Affiliates of any property or property rights or any

- -

Contract that requires the Consent of any third party shall be made subject to such Consent being obtained. If such Consent is not obtained, or if an attempted assignment thereof would be ineffective or would affect the rights of Seller or its Affiliate thereunder such that Buyer would not in fact receive all such rights, Seller will cooperate with Buyer in any arrangement that does not constitute a breach of such Contract, including an operating or other services agreement if reasonably required by Buyer, reasonably designed to provide for Buyer the benefits under any such Contract or rights including enforcement for the benefit of Buyer of any and all rights of Seller or its Affiliates against a third party or Governmental Body thereto arising out of the breach or cancellation by such third party or Governmental Body or otherwise. To the extent that Buyer does receive all of the benefits of any such Contract or rights pursuant to the preceding sentence, Buyer shall accept, and shall indemnify Seller from and against, the burdens (including the out-of-pocket costs and expenses incurred by Seller in performing such arrangement) and perform the obligations under such Contract as subcontractor of Seller to the extent of the benefit received, and to the extent such burdens and obligations would have constituted an Assumed Liability if such Contract had been transferred to Buyer at the Closing. Seller shall and shall cause its Affiliates to exercise or exploit their respective rights and options under all such Contracts referred to in this Section 2.4 only as reasonably directed by Buyer. Furthermore, if the other party(ies) to such a Contract subsequently Consent to the assignment of such Contract to Buyer, Buyer shall thereupon agree to assume and perform all liabilities and the obligations arising thereunder after the date of such Consent, at which time such Contract shall be deemed an Asset, without the payment of further consideration, and the obligations so assumed thereunder shall be deemed Assumed Liabilities.

Section 2.5 Settlement of Intercompany Accounts.

At or prior to the Closing, Seller shall cause all intercompany payables, receivables and loans between New England Gas Company or any of the Subsidiaries relating to the Business, on the one hand, and Seller and its Affiliates (other than New England Gas Company and the Subsidiaries), on the other hand, to be settled or cancelled.

ARTICLE III

Section 3.1 Purchase Price.

Subject to the terms and conditions of this Agreement, the aggregate purchase price (the “Purchase Price”) for the Assets owned directly by Seller and for the Stock shall be an amount in cash equal to FIVE HUNDRED SEVENTY-FIVE MILLION DOLLARS ($575,000,000) less the aggregate outstanding principal amount of, and accrued and unpaid interest on, the Assumed Indebtedness as of the Closing Date (the “Estimated Purchase Price”), and as adjusted in accordance with Section 3.2 (as so adjusted, the “Final Purchase Price”), plus the assumption by Buyer at Closing of the Assumed Liabilities (including the Assumed Indebtedness).

Section 3.2 Adjustment to Estimated Purchase Price.

- -

(a) Within 90 days following the Closing Date, Buyer shall prepare and deliver to Seller a statement (the “Closing Statement”), utilizing the same accounting methods, policies, practices, procedures and adjustments as were used in the preparation of the Base Statement as described on Schedule 1.1(a) (and otherwise in accordance with GAAP, with such exceptions to GAAP as indicated on Schedule 1.1(a)) and shall set forth in reasonable detail the amount of Working Capital of the Business as of 11:59 p.m. on the Closing Date (as well as the adjustments contemplated in Section 6.8), and a calculation of the adjustment to the Estimated Purchase Price that is payable based upon the difference between the Working Capital Target and the Working Capital in the Closing Statement. Seller agrees, at no cost to Buyer, to give Buyer and its authorized representatives reasonable access to such employees, officers and other facilities and such books and records of Seller and its Affiliates as are reasonably necessary to allow Buyer and its authorized representatives to prepare the Closing Statement. The Closing Statement shall be prepared in accordance with Schedule 1.1(a). The Base Statement was prepared using the same accounting methods, policies, practices, procedures and adjustments as were used in the preparation of the Financial Statements and otherwise in accordance with GAAP (and with such exceptions to GAAP as indicated on Schedule 1.1(a)).

(b) Following its receipt from Buyer of the Closing Statement, Seller shall have 15 Business Days to review the Closing Statement and to inform Buyer in writing of any disagreement (the “Objection”) that it may have with the Closing Statement, which objection shall specify in reasonable detail Seller's disagreement with the Closing Statement. If Buyer does not receive the Objection within such 15-Business Day period, the amount of Working Capital set forth on the Closing Statement delivered pursuant to Section 3.2(a) shall be deemed to have been accepted by Seller and shall become binding upon Seller. If Seller does timely deliver an Objection to Buyer, Buyer shall then have 15 Business Days from the date of receipt of such Objection (the “Review Period”) to review and respond to the Objection. Seller and Buyer shall attempt in good faith to resolve any disagreements with respect to the determination of the Working Capital of the Business as of the Closing Date or the amount of the adjustment to the Estimated Purchase Price. If they are unable to resolve all of their disagreements with respect to the determination of Working Capital of the Business as of the Closing Date or the amount of the adjustment to the Estimated Purchase Price within 15 Business Days following the expiration of Buyer's Review Period, they may refer, at the option of either Buyer or Seller, their differences to Ernst & Young, or if Ernst & Young declines to accept such engagement, another internationally recognized firm of independent public accountants selected jointly by Buyer and Seller, which accountants shall determine, only with respect to the disagreements so submitted, whether and to what extent, if any, the amount of Working Capital of the Business as of the Closing Date set forth in the Closing Statement requires adjustment. If Buyer and Seller are unable to so select the independent public accountants within 15 Business Days of Ernst & Young declining to accept such engagement, either Buyer or Seller may thereafter request that the American Arbitration Association make such selection (as applicable, Ernst & Young, the firm selected by Buyer and Seller or the firm selected by the American Arbitration Association is herein referred to as the “CPA Firm”). Buyer and Seller shall direct the CPA Firm to use its reasonable best efforts to render its determination within 30 days after the issue is first submitted to the CPA Firm. The CPA Firm’s determination shall be conclusive and binding upon Buyer and Seller. The fees and disbursements of the CPA Firm shall be shared equally by Buyer and

- -

Seller. Buyer and Seller shall make readily available to the CPA Firm all relevant books and records relating to the Closing Statement and all other items reasonably requested by the CPA Firm. The Closing Statement as agreed to by Buyer and Seller or as determined by the CPA Firm shall be referred to as the “Final Closing Statement.”

(c) In the event of a positive difference between Working Capital on the Final Closing Statement from the Working Capital Target, Buyer shall pay to Seller in cash the amount of such difference, plus the Settlement Interest thereon. In the event of a negative difference between the Working Capital Target from the Working Capital on the Final Closing Statement, Seller shall pay to Buyer in cash the amount of such difference, plus the Settlement Interest thereon. All amounts payable under this Section 3.2(c) shall be paid within five Business Days of the determination of the Final Closing Statement by wire transfer of immediately available funds to a bank account in the United States of America designated in writing by the recipient not less than one Business Day before such payment.

Section 5.13 Employee Benefit Matters.

(a) Schedule 5.13(a) contains a true and complete list of each deferred compensation and each incentive compensation, stock purchase, stock option and other equity compensation plan, program, agreement or arrangement; each severance or termination pay, medical, surgical, hospitalization, life insurance and other “welfare” plan, fund or program (within the meaning of section 3(1) of ERISA); each profit-sharing, stock bonus or other “pension” plan, fund or program (within the meaning of section 3(2) of ERISA); each employment, termination or severance agreement; and each other employee benefit plan, fund, program, agreement or arrangement, in each case, that is sponsored, maintained or contributed to or required to be contributed to by the Seller or by any trade or business, whether or not incorporated (an “ERISA Affiliate”), that together with the Seller would be deemed a “single employer” within the meaning of section 4001(b) of ERISA, or to which the Seller or an ERISA Affiliate is party for the benefit of any Employee or Former Employee of the Seller (the “Employee Plans”). Seller’s Pension Plans and Seller’s 401(k) Plan are the only Employee Plans that are intended to be qualified under Section 401(a) of the IRC. Each employee benefit plan (within the meaning of Section 3(3) of ERISA) that is sponsored, maintained or contributed to or required to be contributed to by Seller or an ERISA Affiliate of Seller and that is subject to

- -

Section 302 or Title IV of ERISA or section 412 of the IRC is hereinafter referred to as a “Title IV Plan.”

(c) No liability under Title IV or section 302 of ERISA has been incurred by the Seller or any ERISA Affiliate that has not been satisfied in full, and no condition exists that presents a material risk to the Seller or any ERISA Affiliate of incurring any such liability, other than liability for premiums due the Pension Benefit Guaranty Corporation (“PBGC”) (which premiums have been paid when due). Insofar as the representation made in this Section 5.13(c) applies to sections 4064, 4069 or 4204 of Title IV of ERISA, it is made with respect to any employee benefit plan, program, agreement or arrangement subject to Title IV of ERISA to which the Seller or any ERISA Affiliate made, or was required to make, contributions during the five (5)-year period ending on the last day of the most recent plan year ended prior to the Closing Date.

(d) The PBGC has not instituted proceedings to terminate any Title IV Plan and no condition exists that presents a material risk that such proceedings will be instituted.

(e) No Title IV Plan or any trust established thereunder has incurred any “accumulated funding deficiency” (as defined in section 302 of ERISA and section 412 of the IRC), whether or not waived, as of the last day of the most recent fiscal year of each Title IV Plan ended prior to the Closing Date. All contributions required to be made with respect to any Employee Plan on or prior to the Closing Date have been timely made.

(f) No Title IV Plan is a “multiemployer pension plan,” as defined in section 3(37) of ERISA, nor is any Title IV Plan a plan described in section 4063(a) of ERISA. Neither the Seller nor any ERISA Affiliate has made or suffered a “complete withdrawal” or a “partial withdrawal,” as such terms are respectively defined in sections 4203 and 4205 of ERISA (or any liability resulting therefrom has been satisfied in full).

(g) Neither the Seller or any Subsidiary, any Employee Plan, any trust created thereunder, nor any trustee or administrator thereof has engaged in a transaction in connection with which the Seller or any Subsidiary, any Employee Plan, any such trust, or any trustee or administrator thereof, or any party dealing with any Employee Plan or any such trust could be subject to either a civil penalty assessed pursuant to section 409 or 502(i) of ERISA or a tax imposed pursuant to section 4975 or 4976 of the IRC.

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

- -

(i) Each Employee Plan intended to be “qualified” within the meaning of section 401(a) of the IRC is so qualified and the trusts maintained thereunder are exempt from taxation under section 501(a) of the IRC. Each Employee Plan intended to satisfy the requirements of Section 501(c)(9) has satisfied such requirements.

(j) Except as disclosed in Schedule 5.13(j), no Employee Plan provides medical, surgical, hospitalization, death or similar benefits (whether or not insured) for Employees or Former Employees of the Seller or any Subsidiary for periods extending beyond their retirement or other termination of service, other than (i) coverage mandated by applicable law, (ii) death benefits under any “pension plan,” or (iii) benefits the full cost of which is borne by the Employee or Former Employee (or his beneficiary).

(l) Except as disclosed in Schedule 5.13(l), the consummation of the transactions contemplated by this Agreement will not, either alone or in combination with another event, (i) entitle any Employee, Former Employee or officer of the Seller or any Subsidiary to severance pay or any other payment, except as expressly provided in this Agreement, or (ii) accelerate the time of payment or vesting, or increase the amount of compensation due any such Employee, Former Employee or officer.

(m) There are no pending, threatened or anticipated claims by or on behalf of any Employee Plan, by any employee or beneficiary covered under any such Employee Plan, or otherwise involving any such Employee Plan (other than routine claims for benefits).

(n) The Subsidiaries do not employ any Employees or any other individuals and do not currently maintain any Employee Plan.

(o) The only representations and warranties given in respect of employee benefit matters are those contained in this Section 5.13 and Section 5.14 and none of the other representations and warranties set forth in this Agreement shall be deemed to constitute, directly or indirectly, a representation or warranty in respect of employee benefit matters.

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

Each of Seller and Buyer shall use their respective commercially reasonable efforts to furnish the information required to be included by the SEC in the Proxy Statement. After consultation with Buyer, Seller shall respond promptly to any comments made by the SEC with respect to the Proxy Statement and cause a definitive Proxy Statement to be mailed to its stockholders as promptly as practicable following the date of this Agreement, and the parties shall respond promptly to any comments with respect to any other statement or schedule filed by them. No filing of, or amendment or supplement to, the Proxy Statement or any other statement or schedule will be made by Seller without providing Buyer a reasonable opportunity to review and comment on the portions thereof pertaining to the transactions contemplated by this Agreement. If at any time after the date the Proxy Statement is mailed to Seller's stockholders and prior to the Seller Meeting any information relating to Seller, Buyer or any of their respective affiliates, officers or directors, should be discovered by Seller or Buyer which is required to be set forth in an amendment or supplement to the Proxy Statement, so that the Proxy Statement will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other parties and an appropriate amendment or supplement describing such information shall be promptly filed with the SEC and, to the extent required by law, rule or regulation, disseminated to the stockholders of Seller.

(iv) Recommendation. Seller, acting through the board of directors of Seller, shall (a) recommend adoption of this Agreement and the transactions contemplated hereby and include such recommendation in the Proxy Statement, and (b) use its commercially reasonable efforts to solicit and obtain such adoption. Neither the board of directors of Seller nor any committee thereof shall directly or indirectly (x) withdraw (or amend or modify in a manner adverse to Buyer), or publicly propose to withdraw (or amend or modify

Buyer will cause such records to be maintained for not less than seven years from the Closing Date and will not dispose of such records without first offering in writing to deliver them to Seller; provided, however, that in the event that Buyer transfers all or a portion of the Business to any third party during such period, Buyer may transfer to such third party all or a portion of the books, records, files and documents related thereof, provided such third party transferee expressly assumes in writing the obligations of Buyer under this Section 6.2(b). In addition, on and after the Closing Date, at Seller’s request, Buyer shall make available to Seller and its Affiliates, employees, representatives and agents, those employees of Buyer requested by Seller in connection with any Proceeding, including to provide testimony, to be deposed, to act as witnesses and to assist counsel; provided, however, that (i) such access to such employees shall not unreasonably interfere with the normal conduct of the operations of Buyer and (ii) Seller shall reimburse Buyer for the out-of-pocket costs reasonably incurred by Buyer in making such employees available to Seller. Without limiting the application of Section 6.1(d), all documents or information furnished by Buyer or obtained by Seller or its Representatives hereunder shall be subject to Section 6.1(d).

(c) Seller Guarantees and Surety Instruments. Buyer shall use its commercially reasonable efforts to assist Seller in obtaining full and complete releases on the guarantees, letters of credit, bonds and other surety instruments provided by Seller in connection with the Business or for the benefit of any Subsidiary, all of which have been listed by Seller on Schedule 6.2(c). For purposes of this Section 6.2(c), commercially reasonable efforts shall include: (i) Buyer’s assumption of the Contracts on the terms set forth in this Agreement; and (ii) an obligation on the part of Buyer to provide a guaranty, letter of credit, bond or other surety

- -

instrument at Closing to the extent required by any Contract assumed by Buyer or retained by any Subsidiary at Closing and, in general, no later than 90 days after the Closing Date but effective as of the Closing Date, an equivalent surety instrument to be substituted for any surety instrument provided by Seller to any beneficiary in connection with the Business or for the benefit of any Subsidiary. Buyer shall indemnify, defend and hold harmless Seller and its Affiliates for any and all Losses (in each case without deduction or set off) incurred on account of Seller’s guarantees, letters of credit, bonds and other surety instruments on or after the Closing Date insofar as such Losses relate to any failure of Buyer or any Subsidiary to perform or discharge any Assumed Liability following the Closing.

Section 6.3 Governmental Filings.

(a) HSR Act Filing. Buyer and Seller shall use reasonable efforts to make an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the transactions contemplated hereby within ten Business Days following the execution of this Agreement. Buyer and Seller shall supply as promptly as practicable any additional information or documentary material that may be requested pursuant to the HSR Act and shall take all other actions necessary to cause the expiration or termination of the applicable waiting periods under the HSR Act as soon as practicable. Buyer and Seller shall comply substantially with any additional requests for information, including requests for production of documents and production of witnesses for interviews or depositions, made by the Antitrust Division of the United States Department of Justice, the United States Federal Trade Commission or the antitrust or competition law authorities of any other jurisdiction (the “Antitrust Authorities”) and take all other reasonable actions to obtain clearance from the Antitrust Authorities, or if such clearance cannot be obtained, to reach an agreement, settlement, consent providing for divestiture, a “hold separate” agreement, contractual undertakings with third parties or any other relief with the concerned Antitrust Authority in order to permit the consummation of the transactions contemplated by this Agreement. Buyer shall exercise its commercially reasonable efforts, and Seller shall cooperate fully with Buyer, to prevent the entry in any Proceeding brought by an Antitrust Authority or any Governmental Body of an Order that would prohibit, make unlawful or delay the consummation of the transactions contemplated by this Agreement. Seller shall not oppose any efforts of Buyer, including Buyer’s proffer of consent to any Order, to complete lawfully the transactions contemplated by this Agreement, and shall cooperate in good faith with Buyer and the Antitrust Authorities to the same effect. Notwithstanding the foregoing, neither party shall be required to agree to any sale, transfer, license, separate holding, divestiture or other disposition of, or to any prohibition of or any limitation on, the acquisition, ownership, operation, effective control or exercise of full rights of ownership (each, a “Divestiture”) relating (x) to the Business to the extent such Divestiture would have a Material Adverse Effect thereon, (y) to The Narragansett Electric Company to the extent that such Divestiture constitutes other than an immaterial restriction on the operations thereof, or (z) to any material business unit of such party or any subsidiary or Affiliate of such party to the extent that such Divestiture would have a material adverse effect thereon.

(b) Other Regulatory Filings. Buyer and Seller will, as soon as reasonably practicable following the execution of this Agreement, but no later than twenty Business Days thereafter with respect to the joint application to the Rhode Island Division of Public Utilities and Carriers, prepare and file with each Governmental Body requests for such

Consents as may be necessary for the consummation of the transactions contemplated hereby in accordance with the terms of this Agreement. Buyer and Seller will diligently pursue such Consents and will cooperate with each other in seeking such Consents. To such end, the parties agree to make available the personnel and other resources of their respective organizations in order to obtain all such Consents. Each party will promptly inform the other party of any communication received by such party from, or given by such party to, any Governmental Body from which any such Consent is required and of any material communication received or given in connection with any Proceeding by a private party, in each case regarding any of the transactions contemplated hereby, and will permit the other party to review any communication given by it to, and consult with each other in advance of any meeting or conference with, any such Governmental Body or, in connection with any Proceeding by a private party, with such other Person, and to the extent permitted by such Governmental Body or other Person, give the other party the opportunity to attend and to participate in such meetings and conferences. Neither party shall take any action in connection with obtaining any Consent from any Governmental Body that is intended to create, allocate, or shift to the other party any liability arising from the obtaining of such Consent. Notwithstanding the foregoing, neither party shall be required to agree to any divestiture of or material restriction on, a material business, a material asset or a material group of related assets that, in any such case, is owned or operated by it or any of its Affiliates.

(c) Seller, with the full cooperation of Buyer, shall take all commercially reasonable actions necessary to effect the transfer or reissuance of any Permit required for the operation of the Assets and the Business, including, without limitation, all Environmental Permits, prior to the Closing Date, to the extent required by applicable Legal Requirements.

No later than 180 days after the Closing Date, Buyer shall cease using any names, marks, trade names, trademarks and corporate symbols and logos incorporating “Southern Union”, “Southern,” “SU,” “SUG,” “New England Gas Company” and “Negasco” (collectively and together with all other names, marks, trade names, trademarks and corporate symbols and logos owned by Seller or any of its Affiliates (other than the Subsidiaries), the “Seller Marks”); shall use commercially reasonable efforts to remove from the Assets any and all Seller Marks and shall amend the relevant Organizational Documents of each Subsidiary to change the name of each Subsidiary to a name that does not include any Seller ▇▇▇▇ or any name or term confusingly similar to any Seller ▇▇▇▇. Thereafter, except as required by Legal Requirement or Order or with the written consent of Seller, Buyer shall not use any Seller ▇▇▇▇ or any name or term confusingly similar to any Seller ▇▇▇▇ in connection with the sale of any products or services, in the corporate or doing business name of any of its Affiliates or otherwise in the conduct of its or any of its Affiliates’ businesses or operations. In the event that Buyer breaches this Section 6.4, Seller shall be entitled to specific performance of this Section 6.4 and to injunctive relief against further violations, as well as any other remedies at law or in equity available to Seller.

Section 6.5 Acknowledgment by Buyer.

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

- -

THE REPRESENTATIONS AND WARRANTIES SET FORTH IN ARTICLE V OF THIS AGREEMENT CONSTITUTE THE SOLE AND EXCLUSIVE REPRESENTATIONS AND WARRANTIES OF SELLER TO BUYER IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY AND BY THE RELATED DOCUMENTS, AND THERE ARE NO REPRESENTATIONS, WARRANTIES, COVENANTS, UNDERSTANDINGS OR AGREEMENTS, ORAL OR WRITTEN, IN RELATION THERETO BETWEEN THE PARTIES OTHER THAN THOSE INCORPORATED HEREIN AND THEREIN. EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES EXPRESSLY SET FORTH IN ARTICLE V OF THIS AGREEMENT, BUYER DISCLAIMS RELIANCE ON ANY REPRESENTATIONS OR WARRANTIES, EITHER EXPRESS OR IMPLIED, BY OR ON BEHALF OF SELLER OR ITS AFFILIATES OR REPRESENTATIVES. WITHOUT LIMITING THE GENERALITY OF THE FOREGOING, BUYER ACKNOWLEDGES AND AGREES THAT, EXCEPT AS PROVIDED IN SECTIONS 5.11, 5.15, 5.16 AND 5.21 THERE ARE NO REPRESENTATIONS OR WARRANTIES OF SELLER WITH RESPECT TO THE CONDITION OF THE ASSETS, COMPLIANCE WITH ENVIRONMENTAL LAWS AND ENVIRONMENTAL PERMITS OR THE PRESENCE OR RELEASES OF HAZARDOUS MATERIAL IN THE FIXTURES, SOILS, GROUNDWATER, SURFACE WATER OR AIR ON, UNDER OR ABOUT OR EMANATING FROM ANY OF THE PROPERTIES OR ASSETS OF SELLER OR ANY SUBSIDIARY.

Section 6.6 Transition Plan.

Within 15 days after the execution date of this Agreement, Buyer shall deliver to Seller a list of its proposed representatives to a joint transition team, which shall include individuals with expertise from various functional specialties associated or involved in providing billing, payroll and other support services provided to the Business by any automated or manual process using facilities or employees that are not included among the Assets or Transferred Employees. Seller will add its representatives to such team within 15 days after receipt of Buyer’s list. Such team will be responsible for preparing as soon as reasonably practicable after the execution date of this Agreement, and timely implementing, a transition plan that will identify and describe substantially all of the various transition activities that the parties will cause to occur before and after the Closing and any other transfer of control matters that any party reasonably believes should be addressed in such transition plan, including the matters set forth on Exhibit 6.6. Buyer and Seller shall use their commercially reasonable efforts to cause their Representatives on such transition team to cooperate in good faith and take all reasonable steps necessary to develop a mutually acceptable transition plan by no later than 60 days after the date of this Agreement. The terms and conditions governing such transition activities will be more fully set forth in a transition services agreement (the “Transition Services Agreement”) reasonably satisfactory to the parties, including the matters set forth on Exhibit 6.6, to be executed and delivered by Buyer and Seller at the Closing.

Section 6.7 Purchase of Leased Assets.

Buyer and Seller shall use commercially reasonable efforts to arrange for Buyer, on the Closing Date, to enter into new lease agreements covering the motor vehicles and other equipment listed on Schedule 6.7 and leased by the lessors to Seller and/or any Subsidiary as identified on Schedule 6.7 (the “Leased Assets”), or if unable to do so, then for Buyer to

- -

purchase any Leased Assets directly from any such lessor on, or promptly after, the Closing Date upon Buyer’s payment directly to any lessor of the purchase price for any of the Leased Assets under the applicable lease. Each party shall be responsible for one-half of any related transfer, registration, sales tax or similar fees associated with the transfer of such leases from Seller to Buyer.

Section 6.8 Meter Reading.

On and prior to the Closing Date, Seller shall read the customer meters in their normal cycle and in due course render the related bills to its customers served by the Business. Seller shall also read each daily read transportation customer meter (collectively, “Large Volume Meters”) on the day immediately preceding the Closing Date. Seller shall provide Buyer with the last meter reading from each of the Large Volume Meters made on the day immediately preceding the Closing Date as soon as practicable after the Closing Date. After the Closing Date, Buyer shall read the customer meters for their first time, in the normal cycle, and in due course render bills for service during the period between Seller’s last reading in the normal cycle and Buyer’s first reading in the normal cycle to the customers. Buyer shall determine the volume of gas sold by Seller prior to the Closing Date through Large Volume Meters by Seller’s meter readings on the day immediately preceding Closing Date. Buyer shall determine by allocation the volumes of gas sold by Seller through all meters other than Large Volume Meters, prior to the Closing Date, and the gas sold by Seller, on and after the Closing Date and prior to its first meter reading through meters without charts. Such allocation shall be consistent with Seller’s past practices for unbilled revenues. Once such determinations have been made by Buyer, the estimated amounts of accounts receivable and earned but unbilled revenue and any other related payables or liabilities shall be adjusted based upon such determinations for purposes of the Working Capital adjustment.

Section 6.9 Insurance.

(a) At Buyer’s request, Seller agrees to use commercially reasonable efforts to assert and diligently pursue all rights to insurance coverage under the Policies (other than with respect to ▇▇▇▇▇▇▇’▇ Compensation and punitive damage policies) and any past insurance policies of Seller relating to the Business or the Assets (such Policies and past insurance policies shall collectively be referred to herein as the “Insurance Policies”) with respect to insured claims asserted prior to the Closing for matters included in the Assumed Liabilities pursuant to Section 2.2(b)(v). Seller retains the exclusive right, in its sole discretion, to make and settle insurance claims under past insurance policies for all matters, whether relating to Assumed Liabilities or Retained Liabilities. As part of any such settlement(s), Seller may relinquish all rights in and to such past insurance policies with respect to such matters, including Assumed Liabilities. Seller shall remit to Buyer insurance proceeds (net of Seller’s costs and expenses) obtained by Seller after Closing with respect to such insured claims allocable to the Assumed Liabilities, as determined by the insurers with whom such claims are settled (or in the absence of such allocation by the insurers, by Seller in proportion to the weight attributable to the claims related to the Assumed Liabilities to the totality of Seller’s claims to such insurers), but in no event shall Buyer be entitled to receive more than $4,000,000 (net of Seller’s costs and expenses) in the aggregate in respect of the Business under such past insurance policies. Subject to the preceding sentence, Seller agrees to use commercially reasonable efforts to negotiate with

- -

each of its insurance companies in order to provide Buyer the benefit of the coverage under the Policies for all claims asserted on or after the Closing Date (to the extent available) and to cooperate with Buyer with any efforts to obtain “tail” coverage, all at Buyer’s sole cost, with respect to any “claims made policies.” Seller shall provide access to Buyer to all of the non-privileged information relating to these matters and shall consult with Buyer on the progress thereof from time to time.

(b) After the Closing, Buyer shall be responsible for, and neither Seller nor any of its Affiliates shall have any responsibility for, the payment of any deductible amounts or underlying limits attributable to the Insurance Policies for claims relating to Assumed Liabilities. Buyer acknowledges that certain of the Insurance Policies may require Seller or any of its Affiliates to provide an indemnity to the insurance carrier for deductible amounts and to provide collateral to secure such indemnity obligations. Buyer shall enter into an indemnification agreement in form mutually acceptable to Buyer and Seller wherein Buyer agrees to indemnify and hold harmless Seller or any of its Affiliates (as applicable) for any and all of the costs of maintaining such collateral and for any charges made against such collateral or indemnification payments in connection with claims arising or alleged to arise from the operations of the Business required to be paid by Seller of any of its Affiliates (as applicable) under or with respect to such Insurance Policies from and after the Closing Date.

(c) Seller makes no representation or warranty with respect to the applicability, validity or adequacy of any Insurance Policies, and Seller shall not be responsible to Buyer or any of its Affiliates for the failure of any insurer to pay under such Insurance Policy.

(d) Nothing in this Agreement is intended to provide or shall be construed as providing a benefit or release to any insurer or claims service organization of any obligation under any Insurance Policy. Nothing herein shall be construed as creating or permitting any insurer or claims service organization the right of subrogation against Seller or Buyer or any of their Affiliates in respect of payments made by one to the other under any Insurance Policy.

Section 6.10 Risk of Loss.

The risk of any loss, damage, impairment, confiscation or condemnation of any of the Assets from any cause whatsoever shall be borne by Seller at all times prior to the Closing, and by Buyer at all times thereafter. If any such loss, damage, impairment, confiscation or condemnation occurs, Seller shall apply the proceeds of any insurance policy, judgment or award with respect thereto to impair, replace or restore the Assets as soon as possible to their prior condition; provided, however, anything contained in this Agreement to the contrary notwithstanding, Seller shall not be obligated to expend sums in excess of the proceeds of any insurance policy, judgment or award with respect to any loss, damage, impairment, confiscation or condemnation of any of the Assets in order to repair, replace or restore such Assets to their prior condition. The provisions of this Section 6.10 shall apply in the event (“Casualty Event”) of any damage or destruction to the Assets which would result in the nonsatisfaction of a condition precedent to Buyer's obligation to consummate this Agreement. If a Casualty Event shall occur, Buyer at its option, may proceed to close this Agreement on the Closing Date, in which event Seller shall pay or assign to Buyer the proceeds from any insurance policies

- -

covering Assets subject to the Casualty Event to the extent such proceeds are received by or payable to Seller and have not been used in or committed to the restoration or replacement of Assets subject to the Casualty Event as of the Closing Date.

Section 6.11 Outstanding Payments and Bank Accounts.

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

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

Section 6.12 Collective Bargaining Agreements.

Seller has advised Buyer that Seller (a) intends to negotiate a renewal or extension of that certain collective bargaining agreement listed on Schedule 6.12(a) and (b) intends to negotiate an early renewal or extension of that certain collective bargaining agreement listed on Schedule 6.12(b). Seller agrees to negotiate such renewals or extensions diligently to achieve commercially reasonable terms and conditions consistent with past practice. Seller shall give Buyer access to all information relating to the renewals or extensions of any such collective bargaining agreement and shall permit Buyer to consult with Seller and its counsel on the progress thereof from time to time. Notwithstanding the foregoing, Seller shall have discretion to conduct such negotiations in the manner consistent with the foregoing standards, but Seller shall not enter into any such renewal or extension without the prior written consent of Buyer , such consent not to be unreasonably withheld.

Section 6.13 Alternative Proposals.

(a) Seller agrees that it shall not, and Seller shall cause its Affiliates and its and its Affiliates' respective Representatives not to, (i) directly or indirectly initiate, solicit, knowingly encourage or facilitate (including by way of furnishing information) any inquiries or the making or submission of any proposal that constitutes, or could reasonably be expected to lead to, an Alternative Proposal, (ii) participate or engage in discussions or negotiations with, or disclose any non-public information or data relating to Seller or any of its Affiliates or afford access to the properties, books or records of Seller or any of its Affiliates to any Person that has made an Alternative Proposal or to any Person in contemplation of an Alternative Proposal, or (iii) accept an Alternative Proposal or enter into any agreement, including any letter of intent, memorandum of understanding, agreement in principle, merger agreement, acquisition

- -

agreement, option agreement, joint venture agreement, partnership agreement or other similar agreement, arrangement or understanding, (A) constituting or related to, or that is intended to or could reasonably be expected to lead to, any Alternative Proposal or (B) requiring, intended to cause, or which could reasonably be expected to cause Seller to abandon, terminate or fail to consummate the sale and transfer of the Assets and Stock to Buyer or any other transaction contemplated by this Agreement.

(b) Seller shall advise Buyer in writing promptly (but in no event more than the later of 24 hours after Seller's or any Affiliate's receipt thereof) of (i) any request for information by any Person in contemplation of an Alternative Proposal, (ii) any Alternative Proposal received from any Person, (iii) the terms and conditions of any such request or proposal, and (iv) the identity of the Person or group making any such request, Alternative Proposal or inquiry, and Seller shall promptly provide to Buyer copies of any written materials received in connection with any of the foregoing.

(c) For purposes of this Agreement, “Alternative Proposal” shall mean any bona fide proposal, whether or not in writing, for the (i) direct or indirect acquisition or purchase of any assets that constitute 10% or more of the net revenues, net income or the assets (based on the fair market value thereof) of the Business, or (ii) direct or indirect acquisition or purchase of any of the Stock; provided, however, that “Alternative Proposal” shall not be deemed to include any proposal to engage in any merger, consolidation, restructuring, or other business combination transaction, sale of shares of capital stock (other than any tracking or similar shares related in whole or in part to the Business or any part thereof), tender offer, exchange offer, recapitalization, stock repurchase program or other similar transaction involving Seller, so long as such transaction would not result in Seller ceasing to own and conduct all or any part of the Business or ceasing to own all or any part of the Assets or Stock.

(d) Immediately after the execution and delivery of this Agreement, Seller shall, and shall instruct its Affiliates and its and their respective Representatives to, terminate any existing activities, discussions or negotiations with any parties conducted heretofore with respect to any possible Alternative Proposal.

(f) No Injunctions. On the Closing Date, there shall be no Orders that operate to restrain, enjoin or otherwise prevent the consummation of the transactions contemplated by this Agreement.

(g) Documents. Seller shall have delivered or shall stand ready to deliver all of the certificates, instruments, Contracts and other documents specified to be delivered by it hereunder, including pursuant to Section 8.1.

- -

(h) No Material Adverse Effect. No occurrence or condition (alone or together with other occurrences or conditions) giving rise to a Material Adverse Effect shall have occurred since the date of this Agreement; for the avoidance of doubt, the failure of Buyer or its designee to have a tariff (including reasonable evidence of the existence of such tariff) sufficient to generate revenues to operate the Business after Closing will be deemed to be a Material Adverse Effect.

(i) Third Party Consents. Seller shall have obtained all Consents of Persons (other than Governmental Bodies) that are required under any loan or credit agreement, note, mortgage, indenture, lease, license, charter or other agreement or instrument in order to consummate the transactions contemplated hereby and such Consents shall remain in full force and effect, other than those the failure of which to obtain or keep in full force and effect would not, individually or in the aggregate, have a Material Adverse Effect.

ARTICLE IX

TERMINATION

Section 9.1 Termination Rights.

This Agreement may be terminated in its entirety at any time prior to the Closing:

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

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

(c) By either party in writing if there shall have been a material breach of or any inaccuracy in any of the representations or warranties set forth in this Agreement on the

- -

part of the other party, which breach is not cured within 30 days following receipt by the breaching party of written notice of such breach from the terminating party, or which breach, by its nature, cannot be cured prior to the Closing; provided, however, that neither party shall have the right to terminate this Agreement pursuant to this Section 9.1(c) unless the breach of representation or warranty, together with all other such breaches, would entitle the party receiving such representation not to consummate the transactions contemplated by this Agreement under Section 7.2(a) (in the case of a breach of representation or warranty by Seller) or Section 7.1(a) (in the case of a breach of representation or warranty by Buyer) and provided, further, that the terminating party is not then in material breach of any representation, warranty, covenant or other agreement contained herein;

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

(e) By either party in writing if the Closing has not occurred by August 25, 2006 (the “Upset Date”); provided, however, that the right to terminate this Agreement under this Section 9.1(e) will not be available to any party that is in material breach of its representations, warranties, covenants or agreements contained herein; and provided further that in the event either party's conditions precedent to Closing set forth in Sections 7.1(d) or 7.1(e) or Sections 7.2(d) or 7.2(e) have not been satisfied prior to the Upset Date but are reasonably capable of being satisfied thereafter, then either party may, following written notice to the other, extend the Upset Date in thirty day increments (up to an aggregate of 120 days);

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

(g) By Buyer, on the one hand, or Seller, on the other hand, in writing if Seller’s Stockholder Approval is not obtained upon the taking of such vote at the Southern Union Company stockholders’ meeting held for the purposes of obtaining such Seller’s Stockholder Approval or any adjournment or postponement thereof; provided that the right to terminate this Agreement pursuant to this Section 9.1(g) shall not be available to Seller if it has not complied with its obligations under Section 6.1(f).

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

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

(b) If this Agreement is terminated as permitted under Section 9.1, such termination shall be without liability of or to any party to this Agreement, or any shareholder or Representative of such party; provided, however, that if such termination shall

- -

result from the willful failure of any party to fulfill a condition to the performance of any other party or to perform a covenant of this Agreement or from a material and willful breach by any party to this Agreement (it being understood that the failure to cure a breach shall not, by itself, be a willful breach of this Agreement), then such party shall (subject to the last sentence of this Section 9.2(b)) be fully liable for any and all damages sustained or incurred by the other party. If prior to Closing either party to this Agreement resorts to legal proceedings to enforce this Agreement, the prevailing party in such proceedings shall be entitled to recover all costs incurred by such party including reasonable attorney’s fees, in addition to any other relief to which such party may be entitled; provided, however, and notwithstanding anything to the contrary in this Section 9.2(b), in no event shall either party be entitled to receive any punitive, exemplary, special, remote, speculative, indirect or consequential damages (including any damages on account of lost profits or opportunities) in connection with any termination of this Agreement.

EMPLOYEE MATTERS

Section 10.1 Employee Agreement.

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

ARTICLE XI

TAX MATTERS

Section 11.1 Purchase Price Allocation.

Within 180 days after the Closing Date, Buyer and Seller shall use their good faith efforts to agree upon the allocation (the “Allocation”) of the Purchase Price to the individual assets or classes of assets within the meaning of Section 1060 of the IRC and the Treasury Regulations thereunder. If Buyer and Seller agree to such Allocation, Buyer and Seller covenant and agree that (a) the values assigned to the assets by the parties’ mutual agreement shall be conclusive and final for all purposes, (b) neither Buyer nor Seller will take any position before any Governmental Body or in any Proceeding that is in any way inconsistent with such Allocation and (c) Buyer and Seller shall file all federal, state, local and foreign Tax Returns and IRS Forms 8594 and 8883 (and any similar forms required for state or local Tax purposes) in accordance with the Allocation. Notwithstanding the foregoing, if Buyer and Seller cannot agree to an Allocation, Buyer and Seller covenant and agree to file, and to cause their respective Affiliates to file, all Tax Returns and schedules thereto (including, for example, amended returns, claims for refund, and those returns and forms required under Section 1060 of the IRC and any Treasury regulations promulgated thereunder) consistent with each of such party’s good faith Allocations, unless otherwise required because of a change in any Legal Requirement. Each of Buyer and Seller agrees to provide the other promptly with any other information reasonably required to complete Form 8594 and Form 8883 (and any similar forms required for state or local Tax

- -

purposes). Each of Buyer and Seller shall notify the other in the event of an examination, audit or other proceeding regarding the Allocation determined under this Section 11.1.

Section 11.2 Cooperation with Respect to Like-Kind Exchange.

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

Section 11.3 Transaction Taxes.

All transfer, documentary, recording, notarial, sales, use, registration, stamp and other similar taxes, fees and expenses (including, but not limited to, all applicable stock transfer, real estate transfer or gains Taxes and including any penalties, interest and additions to such tax) (“Transaction Taxes”) incurred in connection with this Agreement and the transactions contemplated hereby shall be borne one-half by Buyer and one-half by Seller, regardless of whether the Tax authority seeks to collect such Taxes from Seller or Buyer. Buyer and Seller shall cooperate in timely making and filing all Tax Returns as may be required to comply with

- -

the provisions of laws relating to such Transaction Taxes. Seller shall prepare all tax filings related to any Transaction Taxes. Fifteen days prior to making such filings, Seller shall provide to Buyer Seller’s work papers for Buyer’s review and approval. Buyer shall also be responsible for (a) administering the payment of such Transaction Taxes, (b) defending or pursuing any proceedings related thereto and (c) paying any expenses related thereto. Seller shall give prompt written notice to Buyer of any proposed adjustment or assessment of any Transaction Taxes with respect to the transaction, or of any examination of said transaction in a sales, use, transfer or similar Tax audit. In any proceedings, whether formal or informal, Seller shall permit Buyer to participate and control the defense of such proceeding and shall take all actions and execute all documents required to allow such participation. Seller shall not negotiate a settlement or compromise of any Transaction Taxes without the prior written consent of Buyer, which consent shall not be unreasonably withheld or delayed.

Section 11.4 Real and Personal Property Taxes.

All real (including public utility realty tax) and personal property Taxes and assessments arising with respect to the Assets and the assets of Subsidiary and any similar utility Taxes of any other jurisdiction shall be prorated between Buyer and Seller based on the relative periods of time the Assets were owned by each respective party or their respective Affiliates during the fiscal period for which such Taxes are imposed by the applicable taxing jurisdiction (as such fiscal period is or may be reflected on the ▇▇▇▇ rendered by such taxing jurisdiction, but in the case of Taxes imposed based on the specific day of ownership of assets, a fiscal period shall be deemed to be the 365 day period ending with such date). Upon receipt by Buyer of the tax ▇▇▇▇, invoice or other statement regarding such real and personal property Taxes, Buyer shall calculate the pro rata share of such tax ▇▇▇▇, invoice or other statement attributable to Buyer and Seller. Buyer then shall forward, as soon as practicable, to Seller a copy of such tax ▇▇▇▇, invoice or statement along with the supporting documentation relating to the calculation of the pro rata share to Seller. Seller then shall forward to Buyer payment in immediately available funds of its pro rata share of such Taxes as soon as practicable in advance of the due date of the tax ▇▇▇▇, invoice or statement and in time to avoid the incurrence of penalties or interest. Upon its receipt of such payment, Buyer will pay the full amount of the tax ▇▇▇▇, invoice or statement to the applicable taxing authority. In the event Seller first receives a tax ▇▇▇▇, invoice or statement relating to the Assets from a taxing authority, Seller shall immediately forward such tax ▇▇▇▇, invoice or statement to Buyer.

Section 11.5 Other Taxes.

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

- -

foreign law or regulation, (c) any and all Taxes of any Person (other than Seller and its Subsidiaries) imposed on Seller or its Subsidiaries as a transferee or successor, by contract or pursuant to any law, rule, or regulation, which Taxes relate to an event or transaction occurring on or before the Closing, (d) any Taxes of Seller that do not relate to the Business or the Assets purchased pursuant to this Agreement, and (e) any breach or inaccuracy in the representations and warranties set forth in Section 5.9.

Section 11.6 Straddle Period.

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

Section 11.7 Cooperation on Tax Matters.

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

Section 11.8 Tax Returns.

Except as otherwise provided in Sections 11.3 and 11.4,

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

(b) Buyer shall prepare and file or cause to be prepared and filed when due all Tax Returns that are required to be filed by the Subsidiaries or with respect to the Assets for taxable years or periods ending after the Closing Date, and Buyer shall remit or cause to be remitted any Taxes due in respect of such Tax Returns.

- -

(c) Upon the written request of Buyer setting forth in detail the computation of the amount owed, Seller shall pay to Buyer, no later than five (5) days prior to the due date for the applicable Tax Return, the Taxes for which Seller is liable pursuant to Section 11.5 but which are payable with any Tax Return to be filed by Buyer with respect to any Straddle Period.

Section 11.9 Effect of Indemnity Payments.

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

Section 11.10 Survival of Obligations.

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

Section 11.11 Dispute Resolution.

In the event that Seller and Buyer disagree as to the amount or calculation of any payment to be made under this Agreement relating to Taxes, or the interpretation or application of any provision under this Agreement relating to Taxes, the Parties shall attempt in good faith to resolve such dispute. If such dispute is not resolved within sixty (60) days following the commencement of the dispute, Seller and Buyer shall jointly retain a nationally recognized law or accounting firm, which firm is independent of both parties (the “Independent Firm”), to resolve the dispute. The Independent Firm shall act as an arbitrator to resolve all points of disagreement and its decision shall be final and binding upon all parties involved. Following the decision of the Independent Firm, Seller and Buyer shall each take or cause to be taken any action necessary to implement the decision of the Independent Firm. The fees and expenses relating to the Independent Firm shall be borne equally by Seller and Buyer.

Section 11.12 Termination of Tax Agreements.

All Tax allocation, Tax sharing, Tax indemnity or similar agreements between Seller or any of its Affiliates (other than the Subsidiaries), on the one hand, and the Subsidiaries, on the other hand, shall be terminated with respect to the Subsidiaries prior to the Closing Date, and, after the Closing Date, neither Seller or any of its Affiliates (other than the Subsidiaries), on the one hand, nor the Subsidiaries, on the other hand, shall be bound thereby or have any further liability or obligation thereunder to the other party with respect to periods prior to the Closing Date.

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

(b) Notwithstanding anything in this Agreement to the contrary, for purposes of Section 12.1 and this Section 12.3, (x) a breach of a representation or warranty shall be deemed to exist either if such representation or warranty is actually inaccurate or breached or would have been inaccurate or breached if such representation or warranty had not contained any limitation or qualification as to materiality, Material Adverse Effect (which instead will be read as adverse effect or change) or similar language, or any dollar limitation or threshold and (y) the amount of Losses in respect of any breach of a representation or warranty, including any deemed breach resulting from the application of clause (x), shall be determined without regard to any limitation or qualification as to materiality, Material Adverse Effect (which instead will be read as adverse effect or change) or similar language or any dollar limitation or threshold set forth in such representation or warranty.

(c) Except as provided below, the representations and warranties of Seller set forth in this Agreement shall survive the Closing until the date that is eighteen months after the Closing Date; provided however, that (i) the representations and warranties set forth in Section 5.2 (Authority Relative to this Agreement and Binding Effect), in the first two sentences of Section 5.4(a) (Capitalization of the Subsidiaries; Title to Stock), in Section 5.5(a) (Title to Assets; Encumbrances), and in Section 5.18 (Brokers) shall survive indefinitely, (ii) the representations and warranties set forth in Section 5.9 (Taxes) shall survive for a period equal to the applicable statute of limitations for the taxable year for each Tax (giving effect to any extensions or waivers thereof), and (iii) the representations and warranties set forth in Section 5.15 (Environmental Matters) shall survive until the second anniversary of the Closing Date.

5:00 p.m., East Coast time, on the applicable survival termination date set forth above; provided, however, that such indemnities shall survive with respect only to any specific matter that is the subject of a proper Claim Notice delivered in good faith in compliance with the requirements of this Section 12.3 until the earlier to occur of (i) the date on which a final nonappealable resolution of the matter described in such Claim Notice has been reached, including the determination of all related Losses, if any, regardless of when such Losses are finally determined or (ii) the date on which the matter described in such Claim Notice has otherwise reached final resolution, including the determination of all related Losses, if any, regardless of when such Losses are finally determined. In no event shall any amounts be recovered from Seller under Section 12.1 or otherwise for any matter for which a Claim Notice is not delivered to Seller prior to the close of business on the applicable expiration date set forth above.

(d) Notwithstanding anything to the contrary in this Agreement, in no event shall Seller indemnify the Buyer Indemnitees, or be otherwise liable in any way whatsoever to the Buyer Indemnitees, for any Losses (determined after giving effect to the other provisions of this Section 12.3) otherwise subject to indemnification by Seller pursuant to Section 12.1(a) (other than in respect of any claim for any inaccuracy or breach (or deemed inaccuracy or breach) of the representations and warranties contained in the first two sentences of Section 5.4(a) or in Sections 5.5(a) or (c), which claims shall not be subject to the limitations set forth in this Section 12.3(d)) until the Buyer Indemnitees have incurred Losses otherwise indemnifiable pursuant to Section 12.1(a) that in the aggregate exceed Five Million Dollars ($5,000,000) (the “Deductible”), after which Seller shall then be liable for all Losses incurred by the Buyer Indemnitees that are indemnifiable pursuant to Section 12.1(a) in excess of such amount up to the maximum amount set forth in Section 12.3(e). Losses subject to indemnification by Seller pursuant to Section 12.1(a) (other than in respect of any claim for any inaccuracy or breach (or deemed inaccuracy or breach) of the representations and warranties contained in the first two sentences of Section 5.4(a) or in Section 5.5(a)) relating to any single breach or series of related breaches by Seller shall not constitute Losses, and therefore shall not be applied toward the Deductible or be indemnifiable hereunder, unless such Losses relating to any single breach or series of related breaches exceed $20,000.

(e) Notwithstanding anything to the contrary in this Agreement, (i) in no event shall Seller indemnify the Buyer Indemnitees, or be otherwise liable in any way whatsoever to the Buyer Indemnitees, for any Losses (determined after giving effect to the other provisions of this Section 12.3) otherwise subject to indemnification by Seller pursuant to Section 12.1(a) (other than in respect of any claim for any inaccuracy or breach (or deemed inaccuracy or breach) of the representations and warranties contained in the first two sentences of Section 5.4(a) or in Sections 5.5(a) or (c)) that in the aggregate exceed One Hundred Million Dollars ($100,000,000), and (ii) in no event shall Seller indemnify the Buyer Indemnitees, or be otherwise liable in any way whatsoever to the Buyer Indemnitees, for any Losses (determined after giving effect to the other provisions of this Section 12.3) otherwise subject to indemnification by Seller pursuant to Section 12.1(a) (solely in respect of any claim for any inaccuracy or breach (or deemed inaccuracy or breach) of the representations and warranties contained in the first two sentences of Section 5.4(a) or in Sections 5.5(a) or (c)) that in the aggregate exceed the Purchase Price; provided, however, that in the event Seller makes any indemnification payment to any Buyer Indemnitee for any Loss pursuant to Section 12.1(a), regardless of whether such claim is for any inaccuracy or breach (or deemed inaccuracy or

- -

breach) of the representations and warranties contained in the first two sentences of Section 5.4(a) or in Sections 5.5(a) or (c), then the amount of such payment shall be credited against each of the limitations set forth in clause (i) and clause (ii) of this Section 12.3(e).

(f) Seller shall have no liability for any portion of any claim or Loss for which (i) Buyer receives or is entitled to receive (and which are collectible) any insurance proceeds or any indemnity, contribution or other similar payment from any other insurer or other third party (whether in a lump sum or stream of payments) or (ii) Buyer recovers or is entitled to recover through rates, provided that Buyer shall have made a good faith effort to recover any such claim or loss through rates and that such recovery is not indeterminable due to the terms of any rate settlement agreed to by Buyer. No cost or expense relating to any such claim or Loss that is actually recovered on the basis of the foregoing shall be included in determining the extent of Losses suffered by the Buyer Indemnitees for purposes of Section 12.3(c) or Section 12.3(d). Buyer agrees to use its commercially reasonable efforts to give timely and effective written notice to the appropriate insurance carrier(s) of any occurrence or circumstances that, in the judgment of Buyer consistent with its customary risk management practices, appear likely to give rise to a claim against Buyer that is likely to involve one or more insurance policies of Buyer. Any such notice shall be given in good faith by Buyer without regard to the possibility of indemnification payments by Seller under Section 12.1, and shall be processed by Buyer in good faith and in a manner consistent with its risk management practices involving claims for which no third party contractual indemnification is available. Buyer agrees that (x) if it is entitled to receive payment from Seller for a Loss, and (y) if Buyer has obtained insurance that may cover the claim or matter giving rise to such Loss, then (z) such insurance shall be primary coverage and Buyer will make a claim under such insurance (if such claim can be made in good faith) before enforcing its right to receive payment from Seller. If at any time subsequent to the receipt by a Buyer Indemnitee of an indemnity payment from Seller hereunder, such Buyer Indemnitee (or any Affiliate thereof) receives any recovery, settlement or other similar payment with respect to the Loss for which it receives such indemnity payment, such Buyer Indemnitee shall promptly pay to Seller an amount equal to the amount of such recovery, less any expense incurred by such Buyer Indemnitee (or its Affiliates) in connection with such recovery, but in no event shall any such payment exceed the amount of such indemnity payment.

(g) Notwithstanding any language contained in any Related Document (including deeds and other conveyance documents relating to the Real Property), the representations and warranties of Seller set forth in this Agreement will not be merged into any such Related Document and the indemnification obligations of Seller, and the limitations on such obligations, set forth in this Agreement shall control. No provision set forth in any such Related Document shall be deemed to enlarge, alter or amend the terms or provisions of this Agreement.

Section 12.4 Limitation on Buyer’s Liability.

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

Section 12.5 Claims Procedure.

(a) All claims for indemnification under Section 12.1 or 12.2, or any other provision of this Agreement except as otherwise expressly provided in this Agreement, shall be asserted and resolved pursuant to this Article XII. Any Person claiming indemnification hereunder is referred to as the “Indemnified Party” and any Person against whom such claims are asserted hereunder is hereinafter referred to as the “Indemnifying Party.” In the event that any Losses are asserted against or sought to be collected from or threatened to be sought from an Indemnified Party by a third party, including a Governmental Body, said Indemnified Party shall with reasonable promptness provide to the Indemnifying Party a Claim Notice. The Indemnifying Party shall not be obligated to indemnify the Indemnified Party with respect to any such Losses if the Indemnified Party fails to notify the Indemnifying Party thereof in accordance with the provisions of this Agreement in reasonably sufficient time so that the Indemnifying Party’s ability to defend against the Losses is not prejudiced. The Indemnifying Party shall have 30 days from the personal delivery or receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party (i) whether or not it disputes the liability of the Indemnifying Party to the Indemnified Party hereunder with respect to such Losses and/or (ii) whether or not it desires, at the sole cost and expense of the Indemnifying Party, to defend the Indemnified Party against such Losses; provided, however, that any Indemnified Party is hereby authorized prior to and during the Notice Period to file any motion, answer or other pleading that it shall reasonably deem necessary or appropriate to protect its interests or those of the Indemnifying Party (and of which it shall have given notice and opportunity to comment to the Indemnifying Party) and not prejudicial to the Indemnifying Party. In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against such Losses, the Indemnifying Party shall have the right to defend all appropriate proceedings, and with counsel of its own choosing, which proceedings shall be promptly settled or prosecuted by them to a final conclusion. If the Indemnified Party desires to participate in, but not control, any such defense or settlement it may do so at its sole cost and expense. If requested by the Indemnifying Party, the Indemnified Party agrees to cooperate with the Indemnifying Party and its counsel in contesting any Losses that the Indemnifying Party elects to contest or, if appropriate and related to the claim in question, in making any counterclaim against the Person asserting the third party Losses, or any cross-complaint against any Person. No claim may be settled or otherwise compromised without the prior written consent of the Indemnifying Party.

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

(c) With regard to third party claims for which Buyer or Seller is entitled to indemnification under Section 12.1 or 12.2, such indemnification shall be paid by the Indemnifying Party upon (i) the entry of an Order against the Indemnified Party and the expiration of any applicable appeal period or (ii) a settlement with the consent of the

- -

Indemnifying Party, provided that no such consent need be obtained if the Indemnifying Party fails to respond to the Claim Notice as provided in Section 12.5(a). Notwithstanding the foregoing but subject to Section 12.5(a), and provided that there is no dispute as to the applicability of indemnification, expenses of counsel to the Indemnified Party shall be reimbursed on a current basis by the Indemnifying Party as if such expenses are a liability of the Indemnifying Party.

Section 12.6 Exclusive Remedy.

Except (i) for claims arising out of fraud or criminal misrepresentation, and (ii) as otherwise provided in Sections 3.2(b), 6.4, 9.2 or 11.11, the rights, remedies and obligations of the Buyer Indemnitees and the Seller Indemnitees set forth in this Article XII will be the exclusive rights, remedies and obligations of such Persons after the Closing with respect to all post-Closing claims relating to this Agreement, the events giving rise to this Agreement and the transactions provided for herein or contemplated hereby or thereby. Except as provided above, no Proceeding for termination or rescission, or claiming repudiation, of this Agreement may be brought or maintained by either party against the other following the Closing Date no matter how severe, grave or fundamental any breach, default or nonperformance may be by one party. Accordingly, except as otherwise provided in this Section 12.6, the parties hereby expressly waive and forego any and all rights they may possess to bring any such Proceeding.

Notwithstanding the foregoing, Seller may assign all or part of its rights or delegate all or part of its duties under this Agreement, without the prior written consent of Buyer, to a qualified intermediary chosen by Seller to structure all or part of the transactions contemplated hereby as a like-kind exchange of property covered by Section 1031 of the IRC; provided that no such assignment or delegation shall relieve Seller of its obligations hereunder, and Seller shall remain primarily liable to Buyer pursuant to the terms of this Agreement.

Section 13.7 Construction of Agreement.

The terms and provisions of this Agreement represent the results of negotiations between Buyer and Seller, each of which has been represented by counsel of its own choosing, and neither of which has acted under duress or compulsion, whether legal, economic or otherwise. Accordingly, the terms and provisions of this Agreement shall be interpreted and construed in accordance with their usual and customary meanings, and Buyer and Seller hereby waive the application in connection with the interpretation and construction of this Agreement of any rule of law to the effect that ambiguous or conflicting terms or provisions contained in this Agreement shall be interpreted or construed against the party whose attorney prepared the

- -

executed draft or any earlier draft of this Agreement. It is understood and agreed that neither the specification of any dollar amount in the representations and warranties contained in this Agreement nor the inclusion of any specific item in the Schedules or Exhibits is intended to imply that such amounts or higher or lower amounts, or the items so included or other items, are or are not material, and none of the parties shall use the fact of the setting of such amounts or the fact of any inclusion of any such item in the Schedules or Exhibits in any dispute or controversy between the parties as to whether any obligation, item or matter is or is not material for purposes hereof. The word “including” in this Agreement shall mean including without limitation. Words in the singular shall be held to include the plural and vice versa and words of one gender shall be held to include the other genders as the context requires. The terms “hereof,” “herein,” and “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole (including all of the Schedules and Exhibits hereto) and not to any particular provision of this Agreement, and Article, Section, paragraph, Exhibit and Schedule references are to the Articles, Sections, paragraphs, Exhibits and Schedules to this Agreement unless otherwise specified.

Section 13.8 Publicity.

Neither party hereto shall issue, make or cause the publication of any press release or other announcement with respect to this Agreement or the transactions contemplated hereby, or otherwise make any disclosures relating thereto, without the consent of the other party, such consent not to be unreasonably withheld or delayed; provided, however, that such consent shall not be required where such release or announcement is required by applicable law or the rules or regulations of a securities exchange, in which event the party so required to issue such release or announcement shall endeavor, wherever possible, to furnish an advance copy of the proposed release to the other party.

Section 13.9 Waiver.

Except as otherwise expressly provided in this Agreement, neither the failure nor any delay on the part of any party to exercise any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise or waiver of any such right, power or privilege preclude any other or further exercise thereof, or the exercise of any other right, power or privilege available to each party at law or in equity.

Section 13.10 Parties in Interest.

This Agreement (including the documents and instruments referred to herein) is not intended to confer upon any Person, other than the parties hereto and their successors and permitted assigns, any rights or remedies hereunder provided, however, that the indemnification provisions in Article XII shall inure to the benefit of the Buyer Indemnitees and the Seller Indemnitees as provided therein.

All Exhibits and Schedules annexed hereto or referred to herein are hereby incorporated in and made a part of this Agreement as if set forth in full herein. Disclosure of any fact or item in any Schedule referenced by a particular paragraph or Section in this Agreement shall, should the existence of the fact or item or its contents be relevant to any other paragraph or Section, be deemed to be disclosed with respect to that other paragraph or Section whether or not any explicit cross-reference appears therein but only to the extent that such relevance is clearly and readily apparent from the face of such disclosure; provided, however, that notwithstanding the foregoing, no disclosures shall be deemed to be disclosed on Schedule 5.21 except for such disclosures explicitly set forth thereon or explicitly incorporated by reference into Schedule 5.21.

Section 13.14 Counterparts.

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

Section 13.15 Severability.

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

Section 13.16 Consent to Jurisdiction.

The parties hereby irrevocably submit to the exclusive jurisdiction of the courts of the State of New York located in the Borough of Manhattan and the federal courts of the United States of America located in the Southern District of the State of New York over any dispute arising out of or relating to this Agreement or any of the transactions contemplated hereby, and each party irrevocably agrees that all claims in respect of such dispute or proceeding shall be heard and determined in such courts.

Seller shall provide Buyer with a revised Schedule 1.1, updated as of the Closing Date, within ten (10) days following the Closing Date. Seller agrees that, during the period following the execution of the Sale Agreement and prior to the Closing Date, Seller shall not transfer an employee of Seller or any Affiliate of Seller, whose responsibilities prior to the transfer do not pertain primarily to the Business, to a position where the employee has responsibilities that pertain primarily to the Business.

Section 2.2 Collective Bargaining Agreements. Effective as of the Closing Date, Buyer shall assume and agree to perform all obligations of Seller and/or New England Gas

Company under the Collective Bargaining Agreements, and the Collective Bargaining Agreements shall thereafter be binding on Buyer.

Section 2.3 Offers of Employment to Employees

(a) At least thirty (30) days prior to the anticipated Closing Date, Buyer shall offer employment to all Employees (including Employees who are not actively at work on the Closing Date because the Employee is on workers’ compensation, on an approved leave of absence (including an approved leave of absence with a legal or contractual right to reinstatement, military leave, maternity leave, or leave under the Family and Medical Leave Act of 1993) or absent due to vacation, disability, illness or other similar circumstance (each, an “Absent Employee”)), effective as of 12:01 a.m. on the Closing Date (except as provided in the following sentence), with at least the same level of Base Compensation as was in effect for each such Employee immediately prior to the Closing Date. The offer to an Absent Employee shall be made for employment effective as of the expiration of the approved leave of absence or the Absent Employee’s other return from workers’ compensation, vacation, disability, illness or other similar circumstance, provided that such offer of employment shall remain open no later than (1) one hundred eighty (180) days following the Closing Date, or (2) such longer period as may be consistent with applicable Legal Requirements (as to each Absent Employee, the “Absent Employee’s Start Date”). An Absent Employee who does not return to work after the expiration of an approved leave of absence or otherwise under the preceding sentence shall not be considered a Transferred Employee hereunder. Notwithstanding the foregoing, Seller and Buyer agree that the Employees listed in Schedule 2.3(a) may have the opportunity to continue employment with Seller; provided that Buyer shall have reasonable access to the Employees listed in Schedule 2.3(a) prior to and after the Closing Date.

(b) Buyer shall notify Seller of the Employees’ responses to Buyer’s offers of employment under this Section 2.3 as soon as administratively feasible after receiving each Employee’s response. Buyer and Seller shall cooperate fully to facilitate the preparation of Buyer’s offers of employment and such offers shall include the language set forth in Schedule 2.3(b) or similar language reasonably acceptable to Buyer and Seller.

Section 2.4 Employment of Transferred Employees

(a) Buyer shall employ, as of 12:01 a.m. on the Closing Date, all of the Employees who accept Buyer’s offer of employment, except that each Absent Employee shall be deemed employed by Buyer as of 12:01 a.m. on the Absent Employee’s Start Date.

(b) In the event that (1) on the Closing Date or during the Continuation Period, the employment of a Transferred Employee (other than a Transferred Employee covered by a collective bargaining agreement) is terminated by the Buyer or an Affiliate of Buyer, other than For Cause, or (2) during the Continuation Period, Buyer fails to provide a Transferred Employee (other than a Transferred Employee covered by a collective bargaining agreement) with at least the same level of Base Compensation as was in effect immediately prior to the Closing Date, then Buyer shall be responsible for and shall pay to such Transferred Employee, in a lump sum payment, not later than sixty (60) days following the date of the Transferred Employee’s

termination of employment, the following severance benefit (the “Severance Benefits”): two weeks of the Employee’s Base Compensation at termination of employment for each full or partial year of service, measured from the Transferred Employee’s date of hire reflected in Schedule 1.1, not to exceed fifty-two (52) weeks of such Base Compensation; provided, however, that in no event shall such Severance Benefit be less than six (6) weeks of such Base Compensation. The costs incurred, directly or indirectly, in connection with the termination of employment of any Transferred Employee on or after the Closing Date shall be borne exclusively by Buyer. Buyer’s obligation to provide the Severance Benefits shall be subject to the Transferred Employee executing a release of all claims against the Buyer and its Affiliates, and the Seller and its Affiliates, in a form reasonably satisfactory to Buyer.

Section 2.5 Prior Service Credit. On and after the Closing Date, for each Transferred Employee not covered by a Collective Bargaining Agreement and, to the extent consistent with Section 2.2, each Transferred Employee covered by a Collective Bargaining Agreement, Buyer and its Affiliates shall recognize service for Seller, a former owner of the Business, or an Affiliate of either, prior to the Closing Date, for all employee benefit and employment-related purposes, other than for purposes of defined benefit plans and post-retirement health, dental and life insurance benefits (except as required by Section 3.1 or Section 4.6).

Section 2.6 Vacation. Buyer shall permit each Transferred Employee to carry forward (to the same extent allowed to be carried forward by Seller) and to receive paid time off for all vacation days (including sick days and personal days) accrued prior to the Closing Date. As soon as administratively feasible following execution of the Sale Agreement, Seller shall provide to Buyer a list reflecting the paid time off balances standing to the credit of each Transferred Employee as of the date of the Sale Agreement. Seller shall provide Buyer with a revised list, updated as of the Closing Date, within ten (10) days following the Closing Date.

ARTICLE III

PENSION, 401(k) AND NONQUALIFIED PLANS

Section 3.1 Pension Plans. Seller has no defined benefit plans that cover the Employees and that are intended to be qualified plans other than the Southern Union Company ProvEnergy Pension Plan for Non-Bargaining Unit Employees, the Southern Union Company ProvEnergy Pension Plan for Bargaining Unit Employees, the Southern Union Company Valley Resources Employees’ Retirement Plan and the Southern Union Company Valley Resources Employees’ Pension Plan (collectively, “Seller’s Pension Plans”). Effective as of the Closing Date, Buyer shall assume sponsorship of, and all assets (held in trust), liabilities and obligations under, Seller’s Pension Plans, including liability for any contributions due on or after the Closing Date. Seller and Buyer shall take all action necessary and appropriate to establish Buyer, effective as of the Closing Date, as successor to Seller as to all rights, assets (held in trust), duties, liabilities and obligations under or with respect to Seller’s Pension Plans. Buyer shall be responsible for the preparation and filing of any annual reports relating to plan years that include the Closing Date; provided, however, that Seller shall furnish Buyer with such information concerning Seller’s Pension Plans as is necessary to prepare such forms.

Section 3.2 401(k) Plans. Seller has no defined contribution plan that covers the Employees and that is intended to be a qualified plan other than the Southern Union Savings Plan, which includes a qualified cash or deferred arrangement under IRC Section 401(k) (“Seller’s 401(k) Plan”).
