     THIS EIGHTY-THIRD AGREEMENT AMENDING NEW ENGLAND POWER POOL AGREEMENT,
dated as of March 8, 2002 ("Eighty-Third Agreement"), amends the New England
Power Pool Agreement (the "NEPOOL Agreement"), as amended.

     WHEREAS, the NEPOOL Agreement as in effect on December 1, 1996 was amended
and restated by the Thirty-Third Agreement Amending the New England Power Pool
Agreement dated as of December 1, 1996 (the "Thirty-Third Agreement") in the

Agreement") attached to the Thirty-Third Agreement as Exhibit A thereto, and
the Thirty-Third Agreement also provided for the NEPOOL Open Access
Transmission Tariff (the "NEPOOL Tariff") which is Attachment B to the Restated
NEPOOL Agreement; and

     WHEREAS, the Restated NEPOOL Agreement and the NEPOOL Tariff have
subsequently been amended numerous times, the most recent amendment dated as of
January 18, 2002; and

     WHEREAS, the Participants desire to amend the NEPOOL Agreement and the
NEPOOL Tariff, as heretofore amended, to reflect the revisions detailed herein.

     NOW, THEREFORE, upon approval of this Eighty-Third Agreement by the NEPOOL
Participants Committee in accordance with the procedures set forth in the
NEPOOL Agreement, the Participants agree as follows:

                                   SECTION 1
                        AMENDMENTS TO NEPOOL AGREEMENT

1.1  Amendment to Section 21.2(c) of the NEPOOL Agreement.  The second sentence
     of Section 21.2(c) of the NEPOOL Agreement is amended to read as follows:

     If a Participant fails to meet the requirements for continuation of
     service, NEPOOL may take such actions as are specified in the NEPOOL
     Billing Policy attached to the Tariff (the "Billing Policy") and the
     Financial Assurance Policy for NEPOOL Members attached to the Tariff (the
     "Member Financial Assurance Policy").

1.2  Amendment to Section 21.2(d) of the NEPOOL Agreement.  Section 21.2(d) of
     the NEPOOL Agreement is amended to read as follows:

     In the event a Participant fails, for any reason other than a billing
     dispute as described in subsection (c) of this Section 21.2, to pay when
     due in accordance with NEPOOL System Rules (including, without limitation,
     the Billing Policy) all amounts invoiced to it by NEPOOL, or by the
     System Operator on behalf of NEPOOL (a "Payment Default"), or the
     Participant otherwise fails to comply with the Billing Policy or the
     Member Financial Assurance Policy (including, without limitation, a
     failure to provide adequate financial assurance), or the Participant fails
     to perform any other obligation under the Agreement or the Tariff, and
     such failure continues for at least five days in the case of a Payment
     Default and for at least ten days in the case of any other default,
     NEPOOL, or the System Operator on behalf of NEPOOL, may (but shall not be
     required to) notify such Participant in writing, electronically and
     by first class mail sent in each case to such Participant's member or
     alternate on the Participants Committee or billing contact, that it is
     in default, and NEPOOL may initiate a proceeding before the Commission
     to terminate such Participant's status as a Participant.  Simultaneously
     with the giving of the notice described in the preceding sentence
     in the case of a Payment Default and within ten days after the giving of
     such notice in the case of any other default (unless the default giving
     rise to such notice is cured during such period), NEPOOL, or the System
     Operator on behalf of NEPOOL, shall notify each other member and
     alternate on the Participants Committee and each Participant's billing
     contact of the identity of the Participant receiving such notice, whether
     such notice relates to a Payment Default, to a failure to comply otherwise
     with the Billing Policy or the Member Financial Assurance Policy, or to
     another failure to perform obligations under the Agreement or the Tariff,
     and the actions NEPOOL and/or the System Operator plans to take
     and/or has taken in response to such default.  Pending Commission action
     on such termination, NEPOOL may suspend service, in whole or part, to the
     Participant on or after 50 days after the giving of such notice and the
     initiation of such proceeding, in accordance with Commission policy, or
     such shorter time period as is specified in the Billing Policy or the
     Member Financial Assurance Policy, unless the Participant cures the
     default within such period.  Nothing set forth in this Section 21.2 is
     intended to limit the additional provisions of the Information Policy,
     the Member Financial Assurance Policy or the Billing Policy relating to
     defaults.

     Amounts withdrawn from the Late Payment Account and applied toward any
     shortfall resulting from the Default Amount shall not relieve the
     defaulting Participant or defaulting Non-Participant Transmission
     Customer of its obligation to pay such Default Amount.

4.2  Amendment to Section 3.3(j) of the NEPOOL Billing Policy. Section 3.3(j)
     of the NEPOOL Billing Policy is amended as follows:

     (j) Notice and Suspension. Without limiting any of the other remedies
     described above, in the event that the ISO, in its reasonable opinion,
     believes that all or any part of any amount due to be paid by any
     Participant or any Non-Participant Transmission Customer will not be
     or has not been paid when due (a "Payment Default"), the ISO (on its
     own behalf or on behalf of NEPOOL) may (but shall not be required to)
     notify such Participant or Non-Participant Transmission Customer in
     writing, electronically and by first class mail sent in each case to
     such Participant's member or alternate on the Participants Committee
     or billing contact (it being understood that the ISO will use
     reasonable efforts to contact all three) or such Non-Participant
     Transmission Customer's billing contact, of such Payment Default. If a
     Payment Default is not cured within five days after when such payment
     was originally due, the ISO shall notify each member and alternate on
     the NEPOOL Participants Committee, each Participant's billing contact
     and each of the New England governors and utility regulatory agencies
     of (i) the identity of the Participant or Non-Participant Transmission
     Customer receiving such notice, (ii) whether such notice relates to a
     Payment Default, (iii) whether the defaulting Participant has a
     registered load asset, and (iv) the actions the ISO plans to take and/or
     has taken in response to such Payment Default.  In addition, the
     ISO will provide any additional information with respect to such Payment
     Default as may be required under the Information Policy.  If a Payment
     Default is not cured within ten days after when such payment was
     originally due, the defaulting Participant or Non-Participant Transmission
     Customer shall be suspended (if applicable) from (a) making any purchases
     or sales of Market Products in the NEPOOL Market; (b) scheduling
     any future transmission service under the Tariff; and (c) voting on
     matters before the Participants Committee or any Technical Committee, in
     each case until (x) in the case of purchases and sales of Market Products
     and the scheduling of transmission services, such Payment Default has been
     cured in full, and (y) in the case of voting on matters before the
     Participants Committee or any Technical Committee, such Payment Default
     has been cured in full at least three Business Days prior to such vote;
     provided; however, that any suspension of a Participant's authority to
     vote on matters before the Participants Committee or any Technical
     Committee hereunder shall not be effective while an appeal of such
     suspension is pending.  The suspension of a Participant's ability to
     purchase or sell Market Products in the NEPOOL Market shall not limit,
     in any way, NEPOOL's or the ISO's right to invoice or collect payment for
     any amounts owed (whether such amounts are due or becoming due) by such
     Participant under the Documents.  If the ISO has issued a notice that a
     Participant or a Non-Participant Transmission Customer has defaulted on
     a payment obligation and that Participant or Non-Participant Transmission
     Customer subsequently cures that Payment Default, such Participant or
     Non-Participant Transmission Customer may request the ISO to issue a
     notice stating such fact; provided; however, that the ISO shall not be
     required to issue that notice unless, in its sole discretion, the ISO
     determines that such Payment default has been cured.

                                  SECTION 5
                                MISCELLANEOUS

5.1  This Eighty-Third Agreement shall become effective on June 1, 2002, or
     on such other date as the Commission shall provide that the amendments
     reflected herein shall become effective.

5.2  Terms used in this Eighty-Third Agreement that are not defined herein
     shall have the meanings ascribed to them in the NEPOOL Agreement.
