The finding of such independent certified public accountants shall be binding on the Parties hereto. Upon determination of the appropriate adjustment (the "Post-Closing Adjustment") by agreement of the parties or by binding determination of the independent certified public accountants, if the Post- Closing Adjustment is more or less than the Closing Adjustment, the Party owing the difference shall deliver the such difference to the other Party no later than two (2) business days after such determination in immediately available funds or in any other manner as reasonably requested by the payee. 2.8 Allocation of Purchase Price.

In the event that the parties cannot agree on a mutually satisfactory allocation within forty-five (45) days following 8 the execution of this Agreement, the Parties shall appoint independent certified public accountants who shall, at Seller's and Buyer's joint expense, determine the appropriate allocation. The finding of such independent certified public accountants shall be binding on the Parties hereto. Upon determination of the appropriate allocation by agreement of the parties or by binding determination of the accounting firm, the Parties will file all tax returns consistent with such allocation of the Purchase Price, and shall not take any action or position inconsistent with such allocation; provided, however, that if in any audit by the Internal Revenue Service or the taxing authority of any state of any tax return of either Party such allocation is finally determined to be different from the allocation as determined at the Closing, Seller or Buyer may, but shall not be obligated to, take any position or action inconsistent with such allocation as so finally determined. 2.9 [Reserved]. 2.10 Closing Deliveries by Seller.

Upon the occurrence of (i) any one or more Events ---------- of Loss, of which the aggregate costs to restore, repair or replace are reasonably estimated at an amount in excess of two percent (2%) of the Purchase Price, or (ii) any one or more Takings, of which the aggregate condemnation proceeds equal an amount in excess of two percent (2%) of the Purchase Price (a "Major Loss"), Seller shall have, in the case of a Major Loss relating to one or more Events of Loss, the option, exercised by notice to Buyer, to restore, repair or replace the damaged Assets prior to Closing. If Seller elects to restore, repair or replace the Assets relating to a Major Loss, which election shall be made by notice to Buyer within fifteen (15) days following the occurrence of the Major Loss, the completion of the repair, replacement or restoration will be a condition to the Closing and the Closing Date shall be postponed at the election of Seller for the amount of time reasonably necessary to complete the restoration, repair or replacement, not to exceed one hundred and eighty (180) days without Buyer's consent. If Seller elects not to restore, repair or replace the Assets affected by a Major Loss, or such Major Loss is the result of one or more Takings, the provisions of Section 8.1.3 will apply. 24 8.1.3 Equitable Adjustment. In the event that Seller elects not to -------------------- restore, repair or replace a Major Loss, or in the event that Seller, having elected to repair, replace or restore the Major Loss, fails to complete the repair, replacement or restoration within the one hundred eighty (180) days, or in the event that a Major Loss is the result of one or more Takings, then the parties shall, within thirty (30) days following Seller's election, failure to complete, or the occurrence of such Takings, as the case may be, negotiate in good faith an equitable adjustment in the Purchase Price to reflect the impact of the Major Loss, as mitigated by any repair, replacement or restoration work actually completed by Seller, on the Assets being sold to Buyer, and proceed to Closing. To assist Buyer in its evaluation of any and all Events of Loss, Seller shall provide Buyer such access to the Assets and such information as Buyer may reasonably request in connection therewith. 8.1.4 Buyer's Election. In the event that the parties fail to reach ---------------- agreement on an equitable adjustment of the Purchase Price within the thirty (30) days provided in Section 8.1.3, then Buyer shall have the election, exercisable by notice to Seller within fifteen (15) days immediately following the expiration of the thirty (30) day period, to either (a) proceed with the consummation of the transaction at Closing, with a reduction in the Purchase Price consistent with Seller's last offer communicated to Buyer, in which event Seller shall assign over or deliver to Buyer at Closing all condemnation proceeds or insurance proceeds which the Seller receives, or to which Seller becomes entitled by virtue of the Events of Loss, less any costs and expenses reasonably incurred by Seller in obtaining such condemnation proceeds or insurance proceeds, or (b) terminate this Agreement, in which event this Agreement shall terminate and neither Party shall thereafter have any obligation or liability to the other by reason of this Agreement. If Buyer fails to make the election within the fifteen (15) day period, Buyer will be deemed to have made the election to proceed with the Closing.

ARTICLE 10 AGREEMENTS RELATIVE TO PERIOD AFTER CLOSING 10.1 Post Closing Cooperation by Buyer. The Parties recognize that, --------------------------------- notwithstanding the transfer of the Assets to the Buyer, Seller will need access to certain information, records and assistance with respect to the Assets relating to the period prior to Closing. Accordingly, the Parties agree as follows: 10.1.1 Information and Administrative Support. For a period of five -------------------------------------- (5) years after the Closing (or, if requested in writing by Seller within five (5) years after the Closing, until the closing of the examination of Seller's federal and state income tax returns for all periods prior to and including the Closing, if later), Buyer agrees that it will, promptly following the request of Seller and at Seller's expense, provide such information and administrative support as will be reasonably requested by Seller to enable Seller to comply with its obligations with respect to the issuance of Forms W-2, 1099 and other tax reports, reports and notices relating to pension, profit sharing, health and other plans, income tax returns, preparation of financial statements and completion of Seller's audit for the two fiscal years ended December 31 following the Closing Date, and other similar matters. 10.1.2 Books and Records. For a period of five (5) years after the ----------------- Closing (or, if requested in writing by Seller within five (5) years after the Closing, until the closing of the examination of Seller's federal and state income tax returns for all periods prior to and including the Closing, if later), Buyer will not dispose of any Records relating to any of the Assets delivered to it by Seller without first giving notice to Seller of its intent to so dispose of such Records, and permitting Seller to retain or copy such Records at Seller's expense as Seller may select. During such period, Buyer will permit Seller to examine and make copies, at Seller's expense, of such Records for any reasonable purpose, including any litigation now pending or hereafter commenced against Seller, or the preparation of income or other tax returns. 10.1.3 Employees. For a period of five (5) years after the Closing, --------- each of Buyer and Seller will make available to the other on a reasonable basis and as requested from time to time by the other party after Closing, those of its employees with knowledge of, or relevant to, the matters described in Sections 5.1 and 5.2 and this Section 10.1 for the purpose of consultation, investigation or testimony in connection therewith. 10.2 Further Assurances. ------------------ 27 (a) From time to time after the Closing Date, without further consideration, the Seller, will, at its own expense, execute and deliver such documents to the Buyer as the Buyer may reasonably request in order to more effectively convey and transfer to, and vest in, the Buyer the Seller's title to the Assets (as described in Section 2.10). From time to time after the date hereof, the Buyer will, at its own expense, execute and deliver such documents to the Seller as the Seller may reasonably request in order to more effectively consummate the sale of the Assets pursuant to this Agreement. (b) To the extent that Seller's rights under any Contract may not be assigned without the consent of another Person, which consent has not been obtained by the Closing Date, this Agreement shall not constitute an agreement to assign the same, if an attempted assignment would constitute a breach thereof, or be unlawful. Seller and Buyer agree that if any consent to an assignment of any Contract shall not be obtained, or if any attempted assignment would be ineffective or would impair Buyer's rights and obligations under the Contract in question, so that Buyer would not in effect acquire the benefit of all such rights and obligations, Seller, to the maximum extent permitted by law and such Contract, shall, concurrently with or promptly after the Closing, appoint Buyer to be the Seller's agent with respect to such Contract, and Seller shall, to the maximum extent permitted by law and such Contract, enter into such reasonable arrangements with Buyer as are necessary to provide Buyer with the benefits and obligations of such Contract, provided that Buyer shall not have any obligation to offer or pay any consideration in order to obtain any such consents, and provided further that Seller shall not make any agreement, arrangement or other understanding affecting the Assets or their operation as a condition for obtaining and such consents without the prior written consent of Buyer. Seller and Buyer shall cooperate and use Commercially Reasonable Efforts after the Closing to obtain an assignment of such Contract to Buyer. (c) To the extent that Seller's rights under any warranty or guaranty described in Section 2.1(i) may not be assigned without the consent of another Person, which consent has not been obtained by the Closing Date, this Agreement shall not constitute an agreement to assign the same, if an attempted assignment would constitute a breach thereof, or be unlawful. Seller and Buyer agree that if any consent to an assignment of any such warranty or guaranty shall not be obtained, or if any attempted assignment would be ineffective or would impair Buyer's rights and obligations under the warranty or guaranty in question, so that Buyer would not in effect acquire the benefit of all such rights and obligations, Seller, shall use Commercially Reasonable Efforts, at Buyer's sole cost and expense, to the extent permitted by law and such warranty or Guaranty, to enforce such warranty or guaranty for the benefit of Buyer so as to the maximum extent possible to provide Buyer with the benefits and obligations of such warranty or guaranty. Notwithstanding the foregoing, Seller shall not be obligated to bring or file suit against any third party, provided that if Seller shall determine not to bring or file suit after being requested by Buyer to do so, Seller shall assign, to the extent permitted by law of any applicable agreement or contract, its rights in respect of the claims so that Buyer may bring or file such suit. 28 10.3 Notification of Transfer. After the Closing, Buyer, with the ------------------------ cooperation of and following consultation with Seller, will notify promptly all relevant Governmental Authorities and all third Persons of the change in ownership of the Assets resulting from the transactions contemplated herein, to the extent required by applicable law or the specific underlying agreements. 10.4 NEPOOL. Buyer shall on or prior to the Closing become a member of ------ NEPOOL. 10.5 Local Area Transmission Support. The Parties intend that the ISO ------------------------------- will have the primary responsibility for ensuring that the operation of the Assets is performed in a manner that is consistent with maintaining a level of system reliability that is comparable to the level achieved when the Assets were operated by Seller. In order to effectuate the ISO's oversight of the operation of the Assets, Buyer agrees to maintain membership in good standing in NEPOOL, and to submit to the governance of the ISO as established by the NEPOOL Agreement. For a period of twelve (12) months following the termination of the Transition Agreement, Buyer will submit to Seller any plan to effect a permanent or long-term shut-down or substantial reduction in existing generation capacity no less than thirty (30) days prior to such shut-down or reduction. If Seller notifies Buyer within the aforementioned thirty (30) day period that implementation of Buyer's plan has been determined to have a material adverse effect on the stability, reliability or operating characteristics of Seller's system or provision of electric service, then Buyer shall not proceed to implement such plan until Buyer and Seller have engaged in good faith negotiations for a period of thirty (30) days, or such shorter period as is required, to negotiate an agreement resolving the matter on terms acceptable to the Parties. Other than as may be required to preserve system reliability or to comply with the requirements of the ISO or NEPOOL, Seller shall not interfere with Buyer's efforts to expand or modify generation capacity at any of the Sites. 10.6 Employees. (a) Except as provided in Section 10.6(c), Buyer is --------- required to offer employment, effective as of the Closing Date, to only those employees of Seller who are members of Local 369 and whose employment responsibilities primarily relate to the Assets. All such offers of employment shall be made in accordance with (i) all applicable laws and regulations, and (ii) the Collective Bargaining Agreement and the Local 369 AOU, as defined in Section 10.6(b) below. (b) Schedule 10.6(b) sets forth the collective bargaining agreement, ---------------- and amendments thereto, to which Seller is a party with Local 369 in connection with the Assets (collectively, the "Collective Bargaining Agreement"), and the Agreement of Understanding between Seller and Local 369 (the "Local 369 AOU"). On the Closing Date, Buyer will assume the Collective Bargaining Agreement, as amended by the AOU, as it relates to Local 369 Employees to be employed at the Assets and comply with all applicable obligations thereunder and will accept and fulfill all obligations under the Local 369 AOU that are designated for Buyer, including but not limited to the obligation of Buyer to recognize the union as the collective bargaining agent. In the event that Buyer shall sell the Assets to a third party prior to May 15, 2000, Buyer shall require such third party to assume and comply with each of the 29 obligations set forth in the "Successor Clause and Continued Employment" section of the Local 369 AOU. Under the terms of the Local 369 AOU, compliance by Buyer with its obligations under this Section 10.6(b) may not be waived by Seller without the consent of Local 369. Except as provided in the Local 369 AOU, Seller shall retain any and all liability under the Group Welfare Benefits Plan for Retirees of Boston Edison. (c) Buyer is required to offer employment to those employees of Seller, other than members of Local 369, who were employed in non-managerial positions to provide services for operation of the Assets at any time during the three month period prior to the Closing Date, at levels of wages and overall compensation not lower than the employees' prior levels for a period of six months. Each person who becomes employed by Buyer pursuant to Section 10.6(a) or Section 10.6(c) shall be referred to herein as a "FBU Employee." To the extent that the number of FBU Employees of the Seller in a non-managerial position (other than members of Local 369) employed by the Buyer at the Closing exceeds thirty (30), following the Closing Date, Seller shall reimburse Buyer for the wages paid by Buyer, and the cost to Buyer of benefits provided, to each such employee in excess of thirty (30), based on the average actual wages and benefits provided to all such non-managerial employees (other than members of Local 369). To the extent such number of employees exceeds thirty (30), Seller's obligation with respect to such employees shall continue for a period of one year from the Closing Date or until any such employee's earlier termination of employment. To the extent such number of employees exceeds forty (40), such obligation with respect to any such employee in excess of forty (40) shall continue for an additional year from the Closing Date or until any such employee's earlier termination of employment. (d) Any individual covered as of the Closing Date pursuant to the provisions of COBRA under any Benefit Plan that is a Group Health Plan, or with respect to whom a qualifying event, as defined under COBRA, has occurred on or prior to the Closing Date and who later elects continuation coverage under COBRA for such qualifying event, shall continue to be covered under such Group Health Plan after Closing in accordance with the provisions of COBRA and such Group Health Plan for such qualifying event. On or before the Closing Date, Seller shall relocate or terminate the employment of all of its employees whose responsibilities primarily relate to the Assets and shall be solely responsible for payments of all wages and compensation including without limitation accrued vacation pay, bonuses, severance pay, overtime, all benefits under any Benefit Plan that become payable on account of such termination of employment or any other amounts to which those employees may be entitled for services rendered prior to their termination or by virtue of their termination; provided, however, that Seller shall be responsible for any severance benefits under the Local 369 AOU payable to the FBU Employees who are members of the Local 369 who voluntarily resign from Buyer after completing at least 30 days of employment with Buyer, within six (6) months of the Closing Date who are eligible for such severance benefits. Seller agrees to timely perform and discharge all requirements under the WARN Act and under applicable state and local laws and regulations for the notification of its employees arising from the sale of the Assets to Buyer up to and including the Closing Date for those employees who will become FBU Employees effective as of the Closing Date. After the 30 Closing Date, Buyer shall be responsible for performing and discharging all requirements under the WARN Act and under applicable state and local laws and regulations for the notification of its employees with respect to the Assets. ARTICLE 11 ENVIRONMENTAL MATTERS 11.1 Environmental Conditions. Except as otherwise provided herein, the ------------------------ Parties intend that the Buyer be solely responsible for any and all Environmental Conditions with respect to the Sites and the Assets, as well as for any and all Remediation resulting from any such Environmental Conditions other than with respect to the Excluded Assets. Seller shall have no liability to Buyer for the existence of any Environmental Condition at the Sites or with respect to the Assets, and shall not have any obligation to undertake any Remediation of any such Environmental Condition. 11.2 Obligations of Seller. Seller shall retain responsibility for --------------------- Environmental Conditions, including any Remediation, with respect to the Excluded Assets. Seller shall also retain responsibility for all matters arising out of the transportation and disposal of Hazardous Substances from the Sites to an Offsite Disposal Facility on or before the Closing Date and for any civil or criminal fines or penalties for violations of Environmental Laws arising from the operation of the Facilities prior to the Closing. 11.3 Environmental Commitments. As part of the Settlement Agreement, ------------------------- Seller has made certain environmental commitments regarding the operation of the Facilities. Such commitments are described in Attachment 6 of the Settlement Agreement, and a copy is attached hereto as Schedule 11.3 (the ------------- "Environmental Commitments"). Buyer agrees to comply with such Environmental Commitments in accordance with their terms, to the extent applicable to the Facilities. Buyer acknowledges that the performance of the Environmental Commitments is a condition of the Settlement Agreement. The Parties agree that Buyer's obligation with respect to the Environmental Commitments shall survive the Closing, and shall be specifically enforceable by Seller to the extent that such Environmental Commitments have not been superseded by other laws and so long as such Environmental Commitments remain enforceable against Seller or Buyer by relevant Governmental Authorities. ARTICLE 12 INDEMNIFICATION, RELEASE AND RELATED MATTERS 12.1 Indemnification by Seller. Seller will indemnify, defend and hold ------------------------- harmless Buyer from and against all Claims asserted against or suffered by the Buyer relating to, resulting from or arising out of the following: 31 (a) any breach by the Seller of any covenant, agreement or obligation of the Seller contained in this Agreement; (b) the failure of Seller to perform its obligations under Section 11.2; (c) the Excluded Liabilities; (d) any Third Party Claims against Buyer based on Seller's ownership or operation of (i) to the extent not expressly assumed by Buyer pursuant to the terms of the Agreement or the Related Agreements, the Assets prior to the Closing, and (ii) the Excluded Assets after the Closing; or (e) any liability which may be asserted by third parties with respect to the Assets as a result of non-compliance with any Bulk Sales Laws. 12.2 Indemnification by Buyer. Buyer will indemnify, defend and hold ------------------------ harmless Seller from and against all Claims asserted against or suffered by the Seller relating to, resulting from or arising out of the following: (a) any breach by the Buyer of any covenant, agreement or obligation of the Buyer contained in this Agreement; (b) the Assumed Liabilities; (c) the failure of the Buyer to perform its obligations under this Agreement, including without limitation Sections 11.1 and 11.3; (d) any Third Party Claims arising out of, or related to, the assignment or purported assignment of Contracts, warranties or guarantees, or any agreements or arrangements between the parties concerning the same; or (e) any Third Party Claims against Seller based on Buyer's ownership or operation of the Facilities and Assets after the Closing. 12.3 Buyer's Release of Seller. Except as provided in Section 12.1, ------------------------- Buyer, for itself and on behalf of the Buyer Group, does hereby release, hold harmless and forever discharge each member of the Seller Group from any and all Claims of any kind or character, whether known or unknown, hidden or concealed, resulting from or arising out of any Environmental Condition, other than the Environmental Conditions retained by the Seller under Section 11.2. Buyer hereby waives any and all rights and benefits that it now has, or in the future may have conferred upon it by virtue of any statute or common law principle of which provides that a general release does not extend to claims which a party does not know or suspect to exist in its favor at the time of executing the release, which if known would have materially affected such party's settlement 32 with the obligor. In this connection, the Buyer hereby acknowledges that factual matters now unknown to it may have given or may hereafter give rise to Claims that are presently unknown, unanticipated and unsuspected, and it further agrees that this release has been negotiated and agreed upon in light of that awareness and it nevertheless hereby intends to release each member of the Seller Group from the Claims described in the first sentence of this Section. 12.4 Notice of Claim. Promptly after obtaining Knowledge of a Claim for --------------- which it is entitled to indemnity under this Article 12, the Party seeking indemnification hereunder (the "Indemnitee") will notify the Party against whom indemnification is sought (the "Indemnitor") in writing of such Claim, including any Third Party Claim (a "Notice of Claim"). A Notice of Claim will specify, in reasonable detail, the facts known to the Indemnitee regarding the Claim. Subject to the terms of this Agreement, the failure to provide (or timely provide) a Notice of Claim will not affect the Indemnitee's rights to indemnification, except to the extent the Indemnitor is prejudiced thereby; provided, however, the Indemnitor is not obligated to indemnify the Indemnitee for the increased amount of any Claim which would otherwise have been payable to the extent that the increase resulted from the failure to deliver timely a Notice of Claim. 12.5 Defense of Third Party Claims. The Indemnitor will have the right to ----------------------------- conduct and control, at its expense, the defense, compromise or settlement of any Third Party Claim or demand set forth in a Notice of Claim with counsel of its choice. If the Indemnitor fails to notify the Indemnitee in writing within thirty (30) days that it intends to undertake a defense or contest a Third Party Claim with due diligence, or the Indemnitor fails to take reasonable steps necessary to defend diligently such Third Party Claim within twenty (20) days after receiving notice from the Indemnitee that the Indemnitee believes the Indemnitor has failed to take such steps, the Indemnitee may undertake its own defense, compromise or settlement and the Indemnitor will be bound by the result obtained by the Indemnitee. Without the prior written consent of the Indemnitee (which consent shall not be unreasonably withheld), the Indemnitor shall not enter into any settlement of any Third Party Claim for which would lead to liability or create any financial or other obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification hereunder. If firm offer is made to settle any Third Party Claim without leading to liability or the creation of a financial or other obligation on the part of the Indemnitee for which the Indemnitee is not entitled to indemnification hereunder and the Indemnitor desires to accept and agree to such offer, the Indemnitor shall give written notice to the Indemnitee to that effect. If the Indemnitee fails to consent to such firm offer within twenty (20) days after its receipt of such notice, the Indemnitee may continue to contest or defend such Third Party Claim and, in such event, the maximum liability of the Indemnitor shall be the amount of such settlement offer, plus reasonable costs and expenses paid or incurred by the Indemnitee up to the date of such notice. Notwithstanding the foregoing, the Indemnitee shall have the right to pay, compromise or settle any Third Party Claim at any time, provided that in such event the Indemnitee shall waive any right to indemnity therefor hereunder unless the Indemnitee shall have first sought the consent of the Indemnitor in writing to such payment, settlement or compromise and such consent was unreasonably withheld or delayed, in which event no claim 33 for indemnity therefor hereunder shall be waived. This Section 12.5 is subject to the rights of any insurance carrier that is defending the Third Party Claim. 12.6 Cooperation. The Party defending the Third Party Claim will (a) ----------- consult with the other Party throughout the pendency of the Third Party Claim regarding the investigation, defense, settlement, compromise, trial, appeal or other resolution thereof; and (b) afford the other Party the opportunity, by notice, to participate and be associated in the defense of the Third Party Claim through counsel chosen by such other Party at its own expense in the defense of any Third Party Claim as to which a Party has elected to conduct and control the defense thereof; provided, however, if the named parties to any such proceedings (including any impleaded parties) include both the Indemnitee and Indemnitor and representation of the Indemnitee and Indemnitor by the same counsel would be inappropriate due to actual or potential differing interests between them, then the Indemnitee shall have the right to retain its own counsel at the cost and expense of the Indemnitor. The Parties will cooperate in the defense of the Third Party Claim. The Indemnitee will make available to the Indemnitor or its representatives all Records and other materials reasonably required for use in contesting any Third Party Claim (subject to the confidentiality provisions) and will furnish such testimony and attend such conferences, discovery proceedings, hearings, trials, and appeals as may be reasonably requested by the Indemnitor in connection therewith. If requested by the Indemnitor, the Indemnitee will cooperate with the Indemnitor and its counsel in contesting any Third Party Claim that the Indemnitor elects to contest or, if appropriate, in making any counterclaim against the Person asserting the claim or demand, or any cross-complaint against any Person. The Indemnitor will reimburse the Indemnitee for any expenses incurred by Indemnitee in cooperating with or acting at the request of the Indemnitor. 12.7 Mitigation and Limitation on Claims. Notwithstanding anything to the ----------------------------------- contrary contained herein: 12.7.1 Reasonable Efforts to Mitigate. The Indemnitee will use ------------------------------ Commercially Reasonable Efforts to mitigate all losses, damages and the like relating to a Claim, including availing itself of any defenses, limitations, rights of contribution, claims against third Persons and other rights at law or equity. The Indemnitee's Commercially Reasonable Efforts shall include the reasonable expenditure of money to mitigate or otherwise reduce or eliminate any loss or expense for which indemnification would otherwise be due, and the Indemnitor shall reimburse the Indemnitee for the Indemnitee's reasonable expenditures in undertaking the mitigation. 12.7.2 Net of Insurance and Tax Benefits. Any Claim is limited to --------------------------------- the amount of actual damages sustained by the Indemnitee, net of (i) the dollar amount of any insurance or other proceeds actually receivable by the Indemnitee or any of its Affiliates with respect to the Claim, and (ii) income tax benefits to the Indemnitee, to the extent realized by the Indemnitee. Any party seeking indemnity hereunder shall use Commercially Reasonable Efforts to seek coverage (including both costs of defense and indemnity) under applicable insurance policies with respect to any such Claims. 34 12.7.3 [Reserved]. 12.7.4 Applicability. The indemnification obligations of the ------------- Parties described in this Article 12 apply only with respect to matters arising under this Agreement, excluding the Related Agreements. Any Claims arising under or pursuant to a Related Agreement shall be governed by the indemnification obligations, if any, in the respective Related Agreement under which the Claim arises. 12.8 No Recourse. To the extent the transfer, conveyance, assignment and ----------- delivery of Assets to Buyer as provided in this Agreement is accomplished by deeds, assignments, easements, leases, licenses, bills of sale, or other instruments of transfer and conveyance, whether executed at the Closing or thereafter, these instruments are made without representation or warranty by, or recourse against, Seller, except as expressly provided in this Agreement or in any such instrument. 12.9 Survival of Representations and Warranties. The representations and ------------------------------------------ warranties of Seller contained in Article 3, and the representations and warranties of Buyer contained in Article 4 will remain in effect until the Closing Date, at which time these representations and warranties will terminate, and will be of no further force or effect. 12.10 Survival of Indemnification Provisions. The provisions of this -------------------------------------- Article 12 shall survive the Closing. 12.11 Remedies Exclusive. From and after the Closing, the remedies set ------------------ forth in this Article 12 constitute the sole and exclusive remedy for any and all Claims relating to this Agreement and are in lieu of any and all other rights and remedies which the Seller or the Buyer may have under this Agreement or otherwise for monetary relief with respect to any breach or failure to perform or with respect to the Assumed or Excluded Liabilities, other than equitable remedies or fraud. Each Party waives any provision of law to the extent that it would limit or restrict the agreements contained in this Article 12. Nothing herein shall prevent either Party from terminating this Agreement in accordance with Article 15. ARTICLE 13 CONDITIONS PRECEDENT TO OBLIGATIONS OF BUYER AT THE CLOSING The obligations of Buyer under this Agreement to complete the purchase of the Assets and assume the Assumed Liabilities are subject to the satisfaction or waiver by Buyer, on or prior to the Closing, of each of the following conditions precedent: 35 13.1 Warranties and Covenants.

No suit, action or other proceeding against any Party ------------- or its Affiliates or any of the Assets shall be pending before any Governmental Authority which seeks to restrain or prohibit any of the transactions contemplated by this Agreement, except for matters that, in the aggregate, will not have a Material Adverse Effect, or to obtain material damages or other material relief in connection with this Agreement or the transactions contemplated hereby. No preliminary or permanent injunction or other order or decree by any Governmental Authority which prevents the consummation of the sale of the Assets contemplated hereby shall have been issued and remain in effect (each party agreeing to use its reasonable best efforts to have any such injunction, order or decree lifted), and no statute, rule or regulation shall have been enacted by any Governmental Authority which prohibits the consummation of the sale of the Assets. 13.4 Seller's Closing Deliveries.

Metering shall be provided as needed for accurate accounting at the ISO of unit output, station service, and interchange with Edison's Transmission System. If the existing metering fails to meet CRS 13 standards at the date of this Agreement Edison shall at its own cost use due diligence to provide metering that meets the requirements of CRS 13 as soon as practicable thereafter, but in no case shall the completion date of the metering changes be later than six months after the date of this Agreement. In lieu of charging Buyer a rate based upon system wide Non-PTF Transmission Facilities, a portion of Buyer's payments under the Purchase and Sale Agreement will be attributed to the right to use the Non-PTF Transmission Facilities serving the Generating Facilities based upon an allocation of the depreciated value of those Facilities. 5.2 Billing Procedures ------------------ The Parties shall prepare monthly invoices for reimbursable services, if any, provided to the other Party. 5.3 Interest on Unpaid Balances --------------------------- Interest on unpaid balances shall be calculated in accordance with FERC regulations, 18 C.F.R. 35.19a (a)(2)(iii). 5.4 Default ------- "Event of Default" shall mean, in relation to a Party (the "Defaulting Party): failure to make any payment that is required hereunder when due or failure to observe or perform any of its material obligations hereunder, and such failure continues for sixty (60) days after the Defaulting Party receives written notice from the Non-Defaulting Party of such failure. Upon an Event of Default, the Non-Defaulting Party may terminate this Agreement provided that they comply with the notice and termination provisions set forth in the FERC's regulations. 14 If there is a billing dispute, obligations pursuant to this Agreement shall continue, but the amount in dispute shall be paid into escrow until the dispute is resolved. If either party fails to perform its obligations under this Agreement, the other Party may seek specific performance to the extent that monetary damages are determined by a court of competent jurisdiction to be an inadequate remedy. 6. Documentation ------------- The Parties shall provide each other with appropriate documentation whenever one Party makes an alteration, change or modification to its property, equipment or facilities that could reasonably be expected to affect the other Party or whenever it is necessary to maximize operational efficiencies and promote safety and environmental compliance. Edison shall provide Buyer with a set of drawings that represent equipment or facilities that shall be jointly used or operated. 7. Confidentiality --------------- Any information specific to the operation of the Generating Facilities which Edison may require in the course of its business shall be provided to Edison and its use shall be governed by the NEPOOL Information Policy (CRS-45) and by the Code of Conduct under FERC Order 889. 8. Damage to Equipment, Facilities and Property -------------------------------------------- Each Party shall be responsible for all physical damage to or destruction of equipment/facilities solely owned by it and its affiliates, regardless of whether the damage is caused by itself, the other Party or the other Party's affiliates, except to the extent of the other Party's negligence or willful or wanton acts or omissions or except as otherwise provided in this Agreement. 15 9. Indemnification --------------- 9.1 Indemnification --------------- Each Party shall defend, indemnify and hold harmless the other Party from and against any claims and/or liability for damage to property, injury to or death of any person, or any other liability incurred by the other Party caused wholly or in part by the negligent, willful or wanton act or omission of the indemnifying Party, its affiliates, subcontractors, employees and agents arising out of or connected with the operation of its own or the other Party's or either Party's affiliates' facilities, equipment and property described in this Agreement, regardless of whether caused in part by the Party indemnified hereunder, to the extent that the indemnifying Party has agreed to assume responsibility and liability under this Agreement; provided, however, that in the case where the indemnified Party has contributed to the damage or injury, the indemnification shall be reduced based upon the relative degree of fault of the Parties. 9.2 Indemnification Procedures -------------------------- Any Party desiring to make a claim for indemnification pursuant to this Section 9 must first provide notice to the other Party in writing of the basis of the claim. Such written notice must be sent by registered or certified mail, postage prepaid, to the other Party as indicated in Section 18. Such notice must be given within one hundred twenty days (120) of the occurrence of the event giving rise to the claim for indemnification. After receiving written notice of a claim for indemnification, neither Party shall compromise or settle such claim except by written agreement signed by an officer of the Party authorized to compromise or settle such claims. 10. Insurance --------- Each Party shall maintain, at its own cost, fire, liability, worker's compensation and such other forms of insurance, in such amounts and on such terms and conditions as is customary and reasonable in the electric utility industry. Each Party shall maintain a certificate or other written evidence of insurance and shall make available a copy of such certificate upon request by the other Party. All insurance shall provide for not less than thirty (30) days' notice of cancellation, change, 16 amendment or nonrenewal of such insurance. Each Party must notify the other Party within five (5) days of receiving a notice of cancellation, change, amendment or nonrenewal of any insurance policy. 11.

Except for the obligations of either Party to make payments under this Agreement for prior obligations, if either Party is rendered wholly or partly unable to perform its obligations under this Agreement because of a Force Majeure event, that Party shall be excused from whatever performance is affected by the Force Majeure event to the extent so affected; provided, however, that the period of excused performance shall only last as long as the period of Force Majeure and provided that the non-performing Party shall: (1) provide prompt notice to the other Party of the occurrence of the Force Majeure giving an estimation of its expected duration and the probable impact on the performance of its obligations hereunder and submitting good and satisfactory evidence of the existence of the Force Majeure; and (2) exercise all reasonable efforts to continue to perform its obligations hereunder; (3) expeditiously take action to correct or cure the Force Majeure and submit good and satisfactory evidence that it is making all reasonable efforts to correct or cure the Force Majeure; (4) exercise all reasonable efforts to mitigate or limit damages to the other Party to the extent such action will not adversely effect its own interest; and (5) provide prompt notice to the other Party of the cessation of the Force Majeure. 12. Dispute Resolution ------------------ The Parties shall attempt in good faith to resolve between themselves any disputes that may arise hereunder. In the event that the Parties are unable to resolve any such dispute, the matter shall be immediately referred to the executives of the Parties who have authority to resolve the dispute. If these executives are unable to agree upon a solution within thirty (30) days, the Parties shall have recourse to mediation, arbitration, or other alternative dispute resolution device of their mutual selection. If the Parties cannot agree on an alternative dispute resolution device, arbitration shall 17 be selected. Any arbitration shall be conducted in accordance with the commercial arbitration rules of the American Arbitration Association unless otherwise agreed upon. The award rendered by any Arbitrator shall, to the extent applicable law permits, be final and binding and judgment may be entered upon it in accordance with the applicable law in any court or regulatory body having jurisdiction thereof. Remedies and damages shall be provided by mutual agreement or in accordance with the procedures of the American Arbitration Association, as appropriate. Any arbitration, mediation or other dispute resolution proceeding shall be kept strictly privileged and confidential, except as necessary for the enforcement of a decision or award of damages. 13. Amendments ---------- This Agreement may not be amended or modified except in writing by or on behalf of the Parties by their duly authorized officers. The Parties shall negotiate in good faith to amend this Agreement if a change in law or other circumstances substantially affects Edison's provision of Interconnection Services. 14. Assignment/Change in Corporate Identity --------------------------------------- This Agreement shall inure to the benefit of and bind the respective successors and permitted assigns of the Parties hereto, but no assignment by either Party shall be made or become effective without the prior written consent of the other Party, except that this Agreement may be assigned without such consent to an affiliate or successor of either Party, or to a person acquiring all or a controlling interest in the business assets of such Party. No assignment or transfer of rights shall relieve the assigning Party from full liability and financial responsibility for performance unless the assignee or transferee agrees in writing and the other Party has so consented in writing. If Buyer terminates its existence as a corporate entity, by merger, acquisition, sale, consolidation or otherwise, or if substantially all of Buyer's assets are transferred to another entity, without complying with this Agreement, Edison shall have the right to seek equitable relief to enjoin Buyer's successor from using the property in any manner that interferes with, impedes or restricts Edison's ability to operate its Transmission and/or Distribution Systems and Edison shall have the right to operate all or part of the Purchased Interconnection Facilities necessary to maintain its Transmission and Distribution Systems. 18 15.
