The Closing Purchase Price shall be subject to a further adjustment pursuant to Section 2.3(c) of this Agreement (the Closing Purchase Price, as so adjusted, the “Purchase Price”).

2.3 Purchase Price Adjustment.

(a) Not later than three Business Days before the Closing Date, the Seller shall provide the Buyers by notice with the Seller’s good-faith estimate of the Net Working Capital, based upon the accounting books and records of the Company (the “Estimated Net Working Capital”), and all underlying documentation supporting the Estimated Net Working Capital. If the Estimated Net Working Capital is greater than $0, then the Initial Purchase Price shall be increased by the amount of such excess. If the Estimated Net Working Capital is less than $0, then the Initial Purchase Price shall be decreased by the amount of such deficit.

(b) Within 60 days after the Closing Date, the Buyers will prepare and deliver to the Seller a written calculation of the Net Working Capital. Buyers will provide copies and otherwise make available to Seller and its representatives the work papers and back-up materials used in calculating the Net Working Capital.

(c) If the Seller has any good faith objections to the Buyers’ calculation of the Net Working Capital, then it must deliver a detailed written statement describing its objections to the Buyers within 20 Business Days after the Buyers deliver their calculation of the Net Working Capital to the Seller. If the Seller does not object to the Buyers’ calculation of Net Working Capital (and any adjustments resulting therefrom) within such 20 Business Day period, then the Seller shall be deemed to have accepted the Buyers’ calculation thereof and any amounts due shall be paid pursuant to clause

11

(d) below. If the Seller does object in a timely manner, the Parties will make a diligent, good faith effort to resolve all such objections. Any payment due pursuant to clause (d) below shall be paid upon resolution of such objections whether between the Parties or by the national accounting firm as set forth below. If the Parties do not resolve all objections to Buyers’ calculation of the Net Working Capital within 10 Business Days after the Buyers receive the Seller’s statement of objections, then the Parties will select a mutually acceptable, nationally-recognized accounting firm (which may not be the regular outside accounting firms of any Party) to resolve any remaining objections. If the Buyers and the Seller do not agree upon the choice of an accounting firm, they will select a nationally-recognized accounting firm by lot (after excluding their respective regular outside accounting firms). The Buyers will collectively pay 50%, and the Seller will pay 50%, of the costs and expenses of any accounting firm so used. The Buyers and the Seller will jointly instruct the accounting firm to compute the disputed items as soon as practicable, and the determination made by such accounting firm will be set forth in writing and will be conclusive and binding upon the Parties. The amount of the Net Working Capital as agreed to by the Buyers and the Seller or as determined by the accounting firm constitutes the Net Working Capital for purposes of clause (d) below.

(d) In the event that the Net Working Capital exceeds the Estimated Net Working Capital, then each Buyer shall pay to Seller in cash that Buyer’s Percentage of the amount of such excess. In the event that the Estimated Net Working Capital exceeds the Net Working Capital, then the Seller shall pay to each Buyer in cash that Buyer’s Percentage of the amount of such excess. All amounts payable under this Section 2.3(d) shall be paid within three Business Days of the determination of the Closing Date Net Working Capital by wire transfer of immediately available funds to a bank account designated in writing by the recipient not less than one Business Day before such payment.

The Buyers will collectively pay 50% and the Seller will pay 50%, of the costs and expenses of any accounting firm so used.

Employee Benefit Plans as of the Closing Date and (b) to cause the Company to have no liability with respect to the Allegheny Employee Benefit Plans after the Closing (whether for contributions, the payment of benefits or otherwise). The Parties also shall take the actions required by Section 7.6 to occur before the Closing.

7. Post-Closing Covenants. The Parties agree as follows with respect to the period following the Closing.

7.1 General. If after the Closing any further action is necessary to carry out the purposes of this Agreement, the Transaction Documents and the contemplated transactions, each of the Parties will take such further action (including the execution and delivery of such further instruments and documents) as any other Party reasonably may request, and the requesting Party will pay all reasonable out-of-pocket costs and expenses of the requested Party (unless the requesting Party is entitled to indemnification for the requested action under Section 9 of this Agreement). No Party, however, will be required to take any action that, in the opinion of counsel, could constitute a violation of any Law.

7.2 Transition. The Seller and its Affiliates will not take any action that is designed or intended to have the effect of discouraging any lessor, licensor, customer, supplier or other business associate of the Company from maintaining the same business relationships with the Company after the Closing as it maintained with the Company prior to the Closing.

7.3 Access to Information.

(a) After the Closing, the Buyers will afford to the Seller and its Representatives access during normal business hours with reasonable notice to the books, records and personnel of the Company and the Facility, and to such other information, and will furnish such cooperation relating to the Company, as the Seller reasonably requests for financial, environmental and regulatory reporting and accounting matters, the calculation of Net Working Capital, the preparation and filing of any Tax Returns, the defense of Tax and indemnity claims, and any other purposes related to this Agreement, the Transaction Documents or the contemplated transactions. In addition, the Seller will afford each Buyer and its Representatives similar access to any books, records or files retained by the Seller relating to the business of the Company.

(b) Each Buyer and Seller will hold, and will use all commercially reasonable efforts to cause its respective Affiliates and its respective officers, employees, directors, counsel, accountants, financial advisors and other representatives to hold, in strict confidence from any other Person all information and documents obtained pursuant to Section 7.3(a), provided that nothing in this sentence shall limit the disclosure by any party of any information (a) to the extent required by statute, rule, regulation or judicial

38

process (provided that if permitted by law, each party agrees to give the other parties prior notice of such disclosure in sufficient time to permit any of such other parties to obtain a protective Order should it so determine), (b) in connection with any litigation to which such party is a party (provided that such party has taken all reasonable actions to limit the scope and degree of disclosure in any such litigation), (c) in an action or proceeding brought by a party in pursuit of its rights or in the exercise of its remedies under this Agreement, (d) to the extent that such documents or information can be shown to have come within the public domain through no action or omission of the disclosing party or its Affiliates and (e) to its Affiliates (but the party shall be liable for any breach by its Affiliates).

7.4 Transfer Taxes. The Buyers on the one hand and the Seller on the other each will pay 50% of all sales, use, transfer, real property transfer, recording, stock transfer and other similar Taxes and fees, if any, arising out of or in connection with the sale of the Interests pursuant to this Agreement, and will indemnify, defend and hold harmless the other and its Representatives with respect to its share of any such Taxes. The Buyers and the Seller shall cooperate in the preparation, execution and filing of all necessary documentation and Tax Returns with respect to such Taxes.

7.5 Securities Law Covenant. No Buyer will transfer or otherwise dispose of any of the Interests, or any interest in the Interests, in such manner as to cause the Seller or its Affiliates to be in violation of the registration requirements of the Securities Act, or applicable federal or state securities or blue sky Laws.

7.6 Employment Matters.

(a) Not later than 14 days before the Closing Date, the Buyers shall cause the New Operator to offer employment to each Employee, effective immediately following the Closing provided that the Closing occurs, at an initial rate of base pay not less than that in effect with respect to the Employee immediately before the Closing and initially at the same location and in a capacity substantially equivalent to the capacity of the Employee immediately before the Closing. The Seller shall, and shall cause the Company and their Affiliates to cooperate with the reasonable requests of Buyers and the New Operator for access to the Employees before Closing for purposes of making such employment offers. Any Employee who accepts such offer of employment shall be referred to herein as a “Transferred Employee.” The Buyers shall cause the Company to terminate, effectively immediately following the Closing, the employment of all Employees and to pay to each Employee who is not a Transferred Employee the cash severance that the Employee would have received from the Seller or its Affiliates had such termination of employment occurred immediately before the Closing. The Buyers also shall, or shall cause the Company to, notify the Seller, on or before the

39

third Business Day following the Closing Date, of the names of the Employees (if any) who are not Transferred Employees. Except as otherwise required by applicable Law, the New Operator shall not be required to continue the employment of any Transferred Employee after the Closing or, except as otherwise provided in this Section 7.6, to continue such employment on any particular terms and conditions.

(b) The Buyers shall procure that the New Operator agrees to (i) provide each Transferred Employee with employee benefits under plans maintained by New Operator (“Post-Closing Benefit Plans”) that are no less favorable in the aggregate than the benefits provided by the New Operator from time to time to its other similarly situated employees, (ii) upon receiving proof of prior creditable coverage, waive all health care plan pre-existing condition requirements, actively at work exclusions, and waiting periods applicable to the Transferred Employees under the Post-Closing Benefit Plans (except to the extent that the requirements, exclusions, or periods applied with respect to the Transferred Employees immediately before the Closing), (iii) credit under the Post-Closing Benefit Plans all health care expenses incurred by the Transferred Employees under the Allegheny Employee Benefit Plans during the year in which the Closing Date occurs and prior to the Closing Date for the purposes of satisfying annual and lifetime deductibles and out of pocket limits, (iv) credit each Transferred Employee with service before the Closing Date for all purposes under the Post-Closing Benefit Plans (other than for purposes of benefit accrual under any defined benefit pension plan) to the extent that such service was credited under the Allegheny Employee Benefit Plans immediately before the Closing, (v) fulfill all obligations for accrued vacation and sick leave earned or accrued by the Transferred Employees as of the Closing Date, including all unused earned, banked and accrued vacation and sick leave that Transferred Employees have earned as of the Closing Date, and (vi) cause the trustee of any Post-Closing Benefit Plan that is a defined contribution plan in which a Transferred Employee participates, as directed by the Employee, to accept as a contribution any distribution to the Transferred Employee from the Allegheny Energy Employee Stock Ownership and Savings Plan that constitutes an “eligible rollover distribution” within the meaning of section 401(a)(31)(D) of the Code and complies with the provisions of both the Allegheny Energy Employee Stock Ownership and Savings Plan and the applicable receiving Post-Closing Benefit Plan; provided, however, that such Post-Closing Benefit Plan shall not be required to accept any distribution from the Allegheny Energy Employee Stock Ownership and Savings Plan in the form of securities of Seller or its Affiliates.

(c) The Seller shall, or shall cause an appropriate Affiliate of the Seller to, be responsible for complying with the requirements of Part 6 of Subtitle B of Title I of ERISA, section 4980B of the Code, and any similar applicable state law, including the notice requirements thereof, with respect to any

40

Employee (or any person who is a qualified beneficiary in respect of an Employee) who has a “qualifying event” (within the meaning of the foregoing statutes) that occurs on or before the Closing Date.

(d) The Buyers acknowledge that the Company does not own any pension assets and that no pension assets of the Seller, if any, will be transferred to the Company or the Buyers.

(e) Nothing contained in this Section 7.6, whether express or implied, is intended to confer upon any Employee or former employee of the Company any right or remedy, including without limitation any right as a third-party beneficiary.

7.7 Non-Use of Allegheny Marks.

(a) The Allegheny Marks appear on some of the properties and assets of the Company, including on signage at the Facility, and on supplies, materials, stationery, brochures, advertising materials, manuals and similar consumable items of the Company. The Buyers acknowledge and agree that they do not have and, upon consummation of the transactions contemplated by this Agreement, will not have, any right, title, interest, license or other right to use the Allegheny Marks.

(b) The Buyers will (i) within 60 days after the Closing Date, remove the Allegheny Marks from, or cover or conceal the Allegheny Marks on, the properties and assets of the Company, including signage at the Facility, and provide written verification thereof to the Seller promptly after completing such removal, (ii) within 14 days after the Closing Date, return or destroy (with proof of destruction) all other assets of the Company that contain any Allegheny Marks that are not removable, and (iii) within 30 days after the Closing Date, file amendments to the certificate, charter, bylaws or other governing documents, or submit notifications or amendments with respect to any Permits, of the Company that use any Allegheny Marks.

(c) Each Buyer agrees never to challenge Parent’s or its Affiliates’ ownership of the Allegheny Marks or any application for registration thereof or any registration thereof or any rights of the Seller or its Affiliates therein as a result, directly or indirectly, of its ownership of the Company.

(d) No Buyer will conduct any business or offer any goods or services under any Allegheny Marks, except as expressly permitted during the transaction period pursuant to Section 7.7(b) above or as permitted pursuant to Parent’s written consent.

(e) No Buyer will send, or cause to be sent, any correspondence or other materials to any Person on any stationery that contains any Allegheny Marks or otherwise operate the Company in any manner that would or

Nothing in this Agreement shall require a Buyer to indemnify Seller in respect of any breach by the other Buyer.

9.4 Matters Involving Third Parties.

(a) If any third party notifies any Party (the “Indemnified Party”) with respect to any matter (a “Third Party Claim”) that may give rise to a claim for indemnification against any other Party (the “Indemnifying Party”) under this Section 9, then the Indemnified Party will promptly notify each Indemnifying Party in writing. Delay on the part of the Indemnified Party in notifying any Indemnifying Party will not relieve the Indemnifying Party from its obligation unless (and then solely to the extent) the Indemnifying Party is actually prejudiced.

(c) So long as the Indemnifying Party is conducting the defense of the Third Party Claim in accordance with Section 9.4(b) of this Agreement, (i) the Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, (ii) the Indemnified Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnifying Party (which consent may not be withheld, conditioned or delayed unreasonably), and (iii) the Indemnifying Party will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnified Party (which consent may not be withheld, conditioned or delayed unreasonably).

47

breach or alleged breach by the Seller of its representations or warranties contained in this Agreement or any inaccuracy in its certificate delivered under Section 8.1(d) until the Buyers’ Indemnitees have suffered Adverse Consequences by reason of all such breaches (or alleged breaches) in excess of a $1,000,000 aggregate deductible, at which point the Seller will be obligated only to indemnify the Buyers’ Indemnitees from and against such further Adverse Consequences.

(b) Subject to Section 9.5(c), the Seller will not be obligated to pay more than $86,000,000 in the aggregate on account of its obligation to indemnify the Buyers’ Indemnitees from and against all Adverse Consequences resulting from, arising out of, relating to, in the nature of or caused by the breach or alleged breach by the Seller of its representations, warranties or covenants contained in this Agreement or any inaccuracy in its certificate delivered under Section 8.1(d), including with respect to the matters set forth in Section 9.6(a) of this Agreement.

(c) The provisions of Sections 9.5(a) and (b) shall not apply to any breaches of representations and warranties in Sections 3.1 through 3.5, 4.1 through 4.5, 4.7, 4.18, and 5.1 through 5.8; provided, however, the Seller will not be obligated to pay more than the Purchase Price in the aggregate on account of its obligation to indemnify the Buyers’ Indemnitees from and against all Adverse Consequences resulting from, arising out of, relating to, in the nature of or caused by the breach or alleged breach by the Seller of such representations or warranties or any inaccuracy in its certificate delivered under Section 8.1(d).

(ii) Any Liability under or related to Environmental Laws arising as a result of or in connection with a Response Action (whether such Response Action commenced before or after the Closing Date) for Hazardous Substances that are disposed at any Off-Site Location in

connection with the ownership or operation of the Facility prior to the Closing Date; or

(iii) Third Party Claims by a Governmental Authority or other Person relating to the storage, transportation, treatment, disposal, discharge, recycling or Release of any Hazardous Substances at any Off-Site Location, including, without limitation, former properties owned or operated by the Company, prior to the Closing Date, or the arrangement by the Company for any storage, transportation, treatment, disposal, discharge, recycling or Release of any such Hazardous Substances at any Off-Site Location, including, without limitation, former properties owned or operated by the Company, prior to the Closing Date.

(b) Each Buyer, for itself and on behalf of its Representatives, hereby irrevocably releases and forever discharges the Seller’s Indemnitees from any and all Adverse Consequences of any kind or character, whether known or unknown, contingent or accrued, arising under or relating to Environmental Laws, including Environmental Laws enacted or amended after the Closing Date, or relating to any claim in respect of any Environmental Condition or Hazardous Substance, with respect to any of the Company, the Facility (other than as provided in Sections 9.2 and 9.6(a) of this Agreement) (collectively, “Environmental Claims”).

9.7 Employment Indemnification.

49

9.8 Other Indemnification Provisions.

(a) The Parties will make appropriate adjustments for Tax benefits, Tax burdens, insurance coverage and third-party indemnification rights in determining Adverse Consequences for purposes of this Section 9. All indemnification payments under this Agreement will, to the maximum extent permitted by Law, be treated by the Parties as adjustments to the Purchase Price.

(b) The Seller’s Indemnitees and the Buyers’ Indemnitees, as appropriate, will use Commercially Reasonable Efforts to mitigate all Adverse Consequences relating to claims for indemnification pursuant to this Section 9, including availing itself of any defenses, limitations, rights of contribution, claims against third parties and other rights at law or equity. For purposes of this Section 9.7(b), Commercially Reasonable Efforts will include the reasonable expenditure of money to mitigate or otherwise reduce or eliminate any loss or expenses for which indemnification would otherwise be due (which reasonable expenditures will be included as Adverse Consequences suffered by the Party incurring such expenditures).

9.9 Exclusive Remedy.

NO PARTY OR THEIR RESPECTIVE REPRESENTATIVES WILL HAVE ANY OTHER REMEDY (STATUTORY, EQUITABLE, COMMON LAW OR OTHERWISE) AGAINST ANY OTHER PARTY WITH RESPECT TO SUCH MATTERS, AND ALL SUCH OTHER REMEDIES ARE HEREBY WAIVED. WITHOUT LIMITING THE FOREGOING, EACH OF THE PARTIES ACKNOWLEDGES AND AGREES THAT NEITHER IT NOR ITS REPRESENTATIVES WILL HAVE ANY REMEDY AFTER THE CLOSING FOR ANY BREACH OF THE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT, EXCEPT AS EXPRESSLY PROVIDED IN SECTION 9 OF THIS AGREEMENT OR IN THE CASE OF FRAUD.

10. Tax Matters. The following provisions will govern the allocation of responsibility as among the Buyers and the Seller for certain Tax matters following the Closing Date:

10.1 Tax Periods Ending on or Before the Closing Date. The Seller will prepare or cause to be prepared and file or cause to be filed when due all Tax Returns of the Company or with respect to the assets or activities of the Company for all periods ending on or prior to the Closing Date that are filed after the Closing Date and will remit all Taxes shown due on such Tax Returns to the extent such Tax liability is not included as a Liability in the determination of Net Working Capital under Section

50

2.3. All such Tax Returns shall be prepared in a manner consistent with past practice.

10.2 Straddle Periods . The Buyers will prepare or cause to be prepared and file or cause to be filed when due any Tax Returns of the Company or with respect to the assets or activities of the Company for Straddle Periods and will remit all Taxes shown due on such Tax Returns. The Buyers will permit the Seller to review and comment on each such Tax Return described in the preceding sentence prior to filing and will make such revisions to such Tax Returns unless the Buyers reasonably determine that a proposed revision is not appropriate. The Seller will pay to the Buyers no later than two days prior to the date on which the Buyers pay the Taxes shown due on the Tax Returns an amount equal to the portion of such Taxes for which the Seller is liable pursuant to this Section 10 to the extent such Tax Liability is not included as a Liability in the determination of Net Working Capital under Section 2.3. To the extent permitted or required by law or administrative practice, the taxable year of the Company which includes the Closing Date shall be treated as closing on (and including) the Closing Date. Where it is necessary for purposes of this Section 10 to apportion between the Seller and the Buyers the Taxes of the Company or with respect to the assets or activities of the Company for a Straddle Period (which is not treated under the immediately preceding sentence as closing on the Closing Date), such liability shall be apportioned between the period deemed to end at the close of the Closing Date, and the period deemed to begin at the beginning of the day following the Closing Date on the basis of an interim closing of the books, except that in the case of any Taxes that are imposed on a periodic basis, the portion of such Tax that shall be allocated to the portion of such Straddle Period ending on the Closing Date will be deemed to be the amount of such Tax for the entire Straddle Period multiplied by a fraction the numerator of which is the number of days in the Straddle Period ending on the Closing Date and the denominator of which is the number of days in the entire Straddle Period. For purposes of this Section 10, if any transaction occurs on the Closing Date but after the Closing has occurred, and that transaction is outside the Ordinary Course of Business or otherwise is with respect to assets and activities of the Company, that transaction shall be treated as having occurred on the day following the Closing Date.

10.3 Tax Indemnification. Except for Taxes included as a Liability in the determination of Net Working Capital under Section 2.3, and not paid over to the Seller in accordance with Section 10.4, the Seller shall indemnify the Buyers from and against and in respect of any and all losses incurred by the Buyers, which may be imposed on, sustained, incurred, or suffered by or assessed against the Buyers, directly or indirectly, to the extent relating to or arising out of (i) any liability for Taxes of the Company or with respect to the assets or activities of the Company for any taxable year or period that ends 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, (ii) any breach of or inaccuracy in the representations and warranties set forth in Section 4.7, or (iii) any liability for Taxes of any Person (other than the Company) imposed on the Company as transferee, successor or otherwise (including any liability arising under Treasury

51

Regulation Section 1.1502-6 or any comparable provisions of foreign, state or local law), which Taxes relate to an event or transaction occurring before the Closing, except that this Section 10.3 shall not apply to Taxes to the extent such Taxes would not have been incurred but for the Buyer or its Affiliates (including the Company) making Tax elections, Tax accounting, or Tax reporting determinations for the Company (or with respect to the assets or activities of the Company on the Closing Date) for a Tax period ending after the Closing Date that are inconsistent with the Tax elections, Tax accounting, or Tax reporting of the Company for Tax periods ending on or prior to the Closing Date, unless such elections or determinations for Tax periods ending after the Closing Date are required by applicable Tax law or such elections or determinations for Tax periods ending on or prior to the Closing Date violate applicable Tax law. Except as set forth in this Section 10.3, the procedures governing indemnification claims under this section 10.3 shall be the same as set forth in Section 9.4 and 9.8 (except that clauses (iii) and (iv) of Section 9.4(b) shall not apply). With respect to any audit or other proceeding for Taxes for Straddle Period under Section 10.2, Buyer shall not consent to any entry of judgment or enter into any settlement of such claim that would increase the Tax liability for the portion of the Straddle Period ending on and including the Closing Date without the prior written consent of Seller (which consent may not be withheld, conditioned or delayed unreasonably).

10.4 Refunds and Tax Benefits; Amended Tax Returns. Any Tax refunds that are received by the Buyers or the Company, and any amounts credited against Tax to which the Buyers or the Company become entitled, that relate to Tax periods ending on or before the Closing Date, or to the portion of the Straddle Period ending on or before the Closing Date, will be for the account of the Seller, and the Buyers will pay over to the Seller any such refund or the amount of any such credit within 15 days after receipt or entitlement thereto. In addition, to the extent that any amount accrued as a Liability for Taxes in the determination of the Net Working Capital under Section 2.3 turns out to be greater than the actual Tax liability as of the Closing Date, the Buyers will pay over to the Seller such excess within 15 days after the actual amount of the Tax liability has been determined. No amended Tax Return or claim for Tax refund may be filed for any Tax Returns for tax periods ending on or prior to the Closing Date without the advance written consent of the Seller. No amended Tax Return or claim for Tax refund may be filed for any Tax Returns for any Straddle Periods under Section 10.2 without the advance written consent of the Seller (which consent may not be withheld, conditioned or delayed unreasonably).

10.5 Cooperation on Tax Matters.

(a) The Parties will cooperate fully, as and to the extent reasonably requested by the other Party, in connection with the filing of Tax Returns pursuant to this Section 10 and any audit, litigation or other proceeding with respect to Taxes. Such cooperation will 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

52

employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. The Company and the Seller agree (i) to retain all books and records with respect to Tax matters pertinent to the Company relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by the Buyers or the Seller, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any taxing authority, and (ii) to give the other Party reasonable notice prior to transferring, destroying or discarding any such books and records and, if the other party so requests, the Company or the Seller, as the case may be, will allow the other Party to take possession of such books and records.

(b) The Parties further agree, upon request, to use Commercially Reasonable Efforts to obtain any certificate or other document from any Governmental Authority or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including without limitation with respect to the transactions contemplated by this Agreement).

10.6 Survival of Obligations. For the avoidance of doubt, notwithstanding any other provision of this Agreement, the obligations of the Parties set forth in this Section 10 shall not be subject to any restrictions or limitations other than those expressly set forth in this Section 10 and shall survive the Closing.

10.7 Tax Treatment. For purposes of all Income Tax Returns, the Buyers and the Seller will each report the acquisition of all of the Interests pursuant to this Agreement as a taxable purchase and sale, respectively, of all of the assets of the Company in exchange for the Purchase Price and the assumption of any liabilities of the Company that are deemed to be assumed for United States federal Income Tax purposes. The Buyers and the Seller shall (i) be bound by such treatment for purposes of determining any Income Taxes, (ii) prepare and file their Income Tax Returns on a basis consistent with each such treatment, and (iii) take no position inconsistent with such treatment on any applicable Income Tax Return or in any proceeding before any tax authority. In the event that such treatment is disputed by any tax authority, the Party receiving notice of the dispute shall promptly notify the other Parties of such dispute.

11. Termination.

(a) The Buyers and the Seller may terminate this Agreement by mutual written consent at any time prior to the Closing;

(b) The Buyers may terminate this Agreement by giving notice to the Seller at any time prior to the Closing in the event (i) the Seller has breached any representation, warranty or covenant contained in this Agreement and such

53

breach causes a Material Adverse Effect, (ii) a Buyer has notified the Seller of the breach (specifying in reasonable detail such breach), and (iii) the breach has continued without cure or written waiver by the Buyers for a period of 30 days after the notice of breach;

(c) The Buyers may terminate this Agreement by giving notice to the Seller at any time prior to the Closing if the Closing does not occur on or before March 27, 2005, by reason of the failure of any condition precedent under Section 8.1 of this Agreement (unless the failure results primarily from a Buyer breaching any representation, warranty or covenant contained in this Agreement);

(d) The Buyers may terminate this Agreement by giving notice to the Seller at any time prior to the Closing if any of the Buyers’ Required Regulatory Approvals, the receipt of which is a condition to the obligation of the Buyers to consummate the Closing as set forth in Section 8.1 of this Agreement, will have been denied (and a petition for rehearing or re-filing of an application initially denied without prejudice will also have been denied), and such denial was not caused by or the result of a breach of this Agreement by a Buyer;

(e) The Seller may terminate this Agreement by giving notice to each Buyer at any time prior to the Closing in the event (i) a Buyer has breached any material representation, warranty or covenant contained in this Agreement in any material respect, (ii) the Seller has notified each Buyer of the breach (specifying in reasonable detail such breach), and (iii) the breach has continued without cure or written waiver by the Seller for a period of 30 days after the notice of breach;

(f) The Seller may terminate this Agreement by giving notice to each Buyer at any time prior to the Closing if the Closing does not occur on or before March 27, 2005, by reason of the failure of any condition precedent under Section 8.2 of this Agreement (unless the failure results primarily from the Seller itself breaching any representation, warranty or covenant contained in this Agreement);

(g) The Seller may terminate this Agreement by giving notice to each Buyer at any time prior to the Closing if any of the Seller’s Required Regulatory Approvals, the receipt of which is a condition to the obligation of the Seller to consummate the Closing as set forth in Section 8.2 of this Agreement, will have been denied (and a petition for rehearing or re-filing of an application initially denied without prejudice will also have been denied), and such denial was not caused by or the result of a breach of this Agreement by the Seller;

(h) The Buyers may terminate this Agreement in the circumstances described in Section 6.9(b);

54

(i) The Seller may terminate this Agreement in the circumstances described in Section 6.2(a); and

(j) Any Party may terminate this Agreement in the event that any Law or Order becomes effective and continues in effect for 90 days restraining, enjoining or otherwise prohibiting or making illegal the consummation of any of the contemplated transactions.

11.2 Effect of Termination. If any Party terminates this Agreement pursuant to Section 11.1 of this Agreement, all rights and obligations of the Parties under this Agreement will terminate without any Liability of any Party to any other Party (except for any Liability of any Party then in breach). No termination of this Agreement, however, will affect the obligations of the Parties pursuant to the Confidentiality Agreement, except to the extent specified in such Confidentiality Agreement.

12. Miscellaneous.

12.1 Press Releases and Public Announcements. No Party will issue any press release or make any public announcement relating to the subject matter of this Agreement prior to the Closing without the prior written approval of the other Parties. Any Party, however, may make any public disclosure it believes in good faith is required by Law or any listing or trading agreement concerning its publicly-traded securities (in which case the disclosing Party will use Commercially Reasonable Efforts to advise the other Parties prior to making the disclosure).

12.2 No Third-Party Beneficiaries. This Agreement will not confer any rights or remedies upon any Person other than the Parties, their respective successors and permitted assigns, the Seller’s Indemnitees (solely in their capacity as such) and the Buyers’ Indemnitees (solely in their capacity as such).

12.3 Entire Agreement. This Agreement (including the Schedules and Exhibits), together with the Confidentiality Agreement and the Transaction Documents, embodies the entire agreement and understanding of the Parties with respect to the transactions contemplated by this Agreement and the Transaction Documents, and supersedes all prior agreements and understandings between or among the Parties with respect to such transactions. There are no representations, warranties, covenants or agreements between or among the Parties with respect to the subject matter set forth in this Agreement and the Transaction Documents, other than those expressly set forth in this Agreement and the Transaction Documents. Without limiting the foregoing, each Buyer acknowledges and agrees that there are no representations, warranties, covenants or agreements between or among the Parties with respect to any material made available to such Buyer pursuant to the terms of the Confidentiality Agreement (including the Due Diligence Materials).

55

12.4 Succession and Assignment. This Agreement will be binding upon and inure to the benefit of the Parties and their respective successors and permitted assigns. No Party may assign either this Agreement or any of its rights, interests or obligations under this Agreement without the prior written approval of the other Parties. No permitted assignment, however, will release the assigning party from primary liability under this Agreement. Notwithstanding the foregoing, before the Closing the ArcLight Buyer may assign its rights under this Agreement with respect to up to 10% of the Interests to one or more Persons it may designate. To effect such an assignment, the assignee must execute and deliver to the Seller an instrument agreeing to be bound by this Agreement as a Buyer with respect to that percentage Interest, whereupon (a) that assignee shall become a Buyer with a Percentage equal to the percentage specified in the assignment and have all rights of the Buyers with respect to its Percentage of the Interests and (b) ArcLight Buyer shall be released from its obligations under this Agreement in respect of the new Buyer’s Percentage of the Interests and its Percentage shall be reduced by an amount equal to the new Buyer’s Percentage; provided, however, that no such assignment shall relieve ArcLight Energy Partners Fund II, L.P. of its obligations under the guaranty provided above its signature on the signature page of this Agreement.

12.5 Counterparts and Facsimile Signatures. This Agreement may be executed in one or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument, and by facsimile.

(a) This Agreement has been negotiated under and will be governed by and construed in accordance with the domestic laws of the State of New York without giving effect to any choice or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York.

Each party hereby irrevocably submits to the jurisdiction of each such court with respect to any such action, suit or proceeding; provided, however, that such consent to jurisdiction is solely for the purpose referred to in this section and shall not be deemed to be a general submission to the

57

jurisdiction of said courts or in the State of New York other than for such purpose. Each party hereby irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such action, suit or proceeding brought in such a court and any claim that any such action, suit or proceeding brought in such a court has been brought in an inconvenient forum.

No waiver by any Party of any provision of this Agreement or any default, misrepresentation or breach of warranty or covenant under this Agreement, whether intentional or not, will be deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant under this Agreement or affect in any way any rights arising by virtue of any prior or subsequent such default, misrepresentation or breach of warranty or covenant.

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

12.11  Expenses. Except as otherwise provided in this Agreement, each Party will bear its own costs and expenses (including legal fees and expenses) incurred in connection with this Agreement and the contemplated transactions.

12.12  Construction. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement must be construed as if drafted jointly by the Parties, and no presumption or burden of proof will arise favoring or disfavoring any Party by virtue of the authorship of any of the provisions of this Agreement. Except where otherwise indicated, all references to Laws (including Environmental Laws, the Code and Treasury Regulations) means such Laws as in existence and as interpreted on the date of this Agreement or any amendment hereto.
