Electric wishes to implement two retail electric pilot programs (the "Pilot Programs"), the first for residential and small commercial and industrial customers located in the cities of Lawrence, Lynn, Northampton, and Worcester for up to 100 million kilowatthours per year (the "Residential and Small Commercial Pilot Program"), and the second for members of the Massachusetts High Technology Council ("MHTC") served under Mass. Electric's G-3 Rate for up to 200 million kilowatthours per year (the "MHTC Pilot Program"); WHEREAS, the implementation of the Pilot Programs requires Mass.

Electric during the Term. The calculation of this credit is shown on Attachment 1 to this amendment. In addition, NEP agrees during the Term to credit Mass. Electric's fixed payments to NEP to assure that the average cost of purchased power expense to Mass.

The Parties agree that, notwithstanding anything to the contrary in the Service Agreement or in the Tariff, the Customer's obligation to purchase electricity under the Service Agreement and the Company's obligation to provide electricity under the Service Agreement shall terminate as of the Contract Termination Date, which shall be determined pursuant to section 2 of this Amendment. Except as provided in Section 7, below, or in a separate contract for power supply, the Company shall have no further obligation to meet the electricity demands of the ultimate customers in the service territory of the Customer on or after the Contract Termination Date, or to make any plan, investment, purchase, or commitment to maintain sufficient generating capacity to provide adequate, continuous, or reliable electricity supplies to the Customer or its ultimate customers on or after such date. 2. The Contract Termination Date shall be defined as the first to occur of the Retail Access Date, determined in accordance with sub-paragraph (a) or the Wholesale Access Date, determined in accordance with sub-paragraph (b). (a) The Retail Access Date shall be the later of (i) January 1, 1998; or (ii) the date when retail access is made available to all ultimate customers of the investor-owned electric utilities in Massachusetts; provided, however, that in the event the condition stated in clause (ii) is not satisfied by January 1, 1998, the Customer in its sole discretion shall have the option to accelerate the Retail Access Date and implement retail access for its ultimate customers in its service territory by providing the Company at least 90 days advance written notice of the date such access shall be made available. (b) The Wholesale Access Date shall be the date upon which the Customer in its sole discretion decides to terminate purchases under Tariff 1 and the Service Agreement, provided that such date shall not be earlier than January 1, 1998 and provided further that the Customer shall give the Company at least 90 days advance written notice of its declaration of the Wholesale Access Date. 3. After the Contract Termination Date, the Customer shall pay to the Company the Contract Termination Charges determined in accordance with Appendix 1 and the Schedules attached to this Amendment, which set forth Base Contract Termination Charges and formulae for the adjustment of the Base Contract Termination Charges. 4. For service under the Tariff prior to the Contract Termination Date, the Company shall charge and the Customer shall pay the Demand and Energy Charges shown on Fifty-third Revised Page No. 1 of Schedule II-A, which sets forth the W-95(S) rates, and, except as provided in footnote 1 below, such charges shall not be subject to change during such period for service to the Customer/1/; provided, however, nothing in this agreement shall preclude the Company from requesting an increase in rates that may become effective after suspension on January 1, 2001, if the Contract Termination Date has not occurred by that time. ______________________ /1/ By April 1 of each year after 1998 during which the Retail Access Date or the Contract Termination Date pursuant to footnote 4 of the Agreement has not occurred, the Company shall file a report with the Commission calculating its return on equity for the prior calendar year using the earnings available for common equity as reported to the Securities and Exchange Commission in the Company's annual report divided by the average of the thirteen monthly common equity balances on the Company's books for the same period. The Company's earnings available for common equity and common equity balances shall be adjusted to eliminate the effects of any writedown and to restore expenses associated with any such writedown that may result from the implementation of industry restructuring or this Agreement. If the Company's return so calculated is above 11.75 percent, it shall calculate the revenue requirement associated with 72.6 percent of the excess above 11.75 percent and shall: (1) refund to the Customer revenues sufficient to cause the Customer's return on equity for the prior calendar year to reach 11.75 percent; and (2) accrue the balance to the Reconciliation Account established under Section 3.4 of this Agreement. The obligation in this footnote shall cease as of the Retail Access Date or the Contract Termination Date pursuant to footnote 4 of the Agreement. 5. Notwithstanding anything to the contrary in the Tariff or the Service Agreement, the Contract Termination Charges specified in Appendix 1 and attached Schedules to this Amendment shall remain in effect until the Company has collected all amounts subject to collection thereunder and neither the Customer's obligation to pay the Contract Termination Charges in full nor the formulae for the calculation of the Contract Termination Charges set forth in Appendix 1 and the attached Schedules to this Amendment shall be subject to change through application to the Federal Energy Regulatory Commission pursuant to the provisions of Section 205 or Section 206 of the Federal Power Act, absent the agreement of the Company or its successors or assigns. 6. Commencing on the Contract Termination Date, the Company (including any successor or assign of the Company that succeeds to the Company's obligations with respect to the operation of its transmission facilities) shall, upon request of the Customer, provide network integration transmission service to the Customer in accordance with the Service Agreement for Network Integration Transmission Service between the Customer and the Company of even date, and with the terms and conditions of the tariff maintained in effect by the Company for such service, or in accordance with the policy of the Federal Energy Regulatory Commission as in effect from time to time. Such service shall be provided to the Customer after the Wholesale Access Date to enable the Customer to integrate its loads and resources and shall be provided to the Customer after the Retail Access Date to enable the ultimate customers in the Customer's service territory to integrate their loads and resources. 7. For the period commencing on the Contract Termination Date and extending through December 31, 2004 (the "Standard Offer Period"), the Company shall provide service to the Customer in accordance with this section 7, such service being referred to as "Standard Offer Service." (a) Standard Offer Service shall be made available at the prices set forth in the Stipulation and Agreement, adjusted for a fuel index. The prices for Standard Offer Service do not include charges for transmission services provided in accordance with section 6 of this Amendment, or charges for distribution services under the Customer's rates for distribution services, but otherwise reflect the price of electricity delivered to the meters of the ultimate customers of the Customer. (b) Standard Offer Service shall be made available by the Company to the Customer after the Wholesale Access Date for the purposes set forth in paragraph D of Schedule I of the Tariff or to the Company for resale to those ultimate customers in the Customer's service territory who elect to purchase Standard Offer Service after the Retail Access Date and have not terminated Standard Offer Service to purchase electricity from another supplier, provided that, neither the Customer nor the ultimate customers shall be required to purchase Standard Offer Service from the Company. For the first year after the Retail Access Date, the Company shall make Standard Offer Service available to all residential or G-1 customers of the Customer, who have previously taken service from an alternative supplier, if such residential or G-1 customer elects to return to Standard Offer Service within 120 days of taking service from the alternative supplier. (c) In the event the Contract Termination Date is determined by the Wholesale Access Date, the Customer shall be free, either in its notice pursuant to section 2(b), or thereafter by giving the Company at least 90 days advance written notice directed to the first day of a calendar month, to terminate or reduce its purchases of Standard Offer Service from the Company in order to obtain electricity from other suppliers in the market. Once the Customer has reduced or terminated its purchases of Standard Offer Service from the Company, the Company shall have no obligation to supply Standard Offer Service to the Customer with respect to the terminated or reduced purchases. (d) No less than 90 days before the Retail Access Date, the Customer shall notify the Company in writing of the quantity of energy it shall purchase under Standard Offer Service for resale to ultimate customers in its service territory. The Customer shall provide the Company with at least 30 days prior advance written notice, directed to the first day of a calendar month, of reductions in the quantity of energy so purchased due to decisions by customers initially electing Standard Offer Service to purchase electricity from other suppliers after the Retail Access Date. Nothing in this Amendment shall restrict the right of any ultimate customer to purchase electricity from other suppliers after the Retail Access Date, provided that, except as set forth in section 7(b), above, once any such ultimate customer has purchased electricity from another supplier, the Company shall have no obligation to supply Standard Offer Service to the Customer for resale to such ultimate customer. (e) The Company acknowledges that the Customer will offer alternative power suppliers the opportunity in an auction to supply electricity to enable the Customer to provide Standard Offer Service to ultimate customers in its service territory after the Retail Access Date. The Company shall be free to bid in the auction, provided that the Company's bid shall not exceed the prices set forth in the Stipulation and Agreement, adjusted for the fuel index set forth in that Agreement. 8. This Amendment shall take effect as of the date it is permitted to become effective by the Federal Energy Regulatory Commission, which date shall be referred to as the "Effective Date." This Amendment, together with all provisions of the Tariff and the Service Agreement necessary to effectuate all provisions of this Amendment, shall remain in effect until all obligations of the parties under this Amendment, including, without limitation, the obligation of the Customer to pay to the Company the Contract Termination Charges, have been discharged in full. Upon the discharge in full of all such obligations, this Amendment and the Service Agreement shall terminate. 9. The provisions of this Amendment shall override any inconsistent provisions of the Service Agreement and, with respect to the Customer, all inconsistent provisions of the Tariff, but all provisions of the Tariff and the Service Agreement that are not inconsistent with this Amendment shall remain in full force and effect. 10. The rights conferred and obligations imposed on the Customer and Company under this Amendment shall be binding on or inure to the benefit of their successors in interest or assignees as if such successor or assignee was itself a signatory hereto. IN WITNESS WHEREOF, the parties have executed this Amendment of Service Agreement as of the date first written above.
