     NOW THEREFORE, this QUEBEC INTERCONNECTION TRANSFER AGREEMENT
("Agreement") is dated as of September 1, 1998, and is made by and between NEP
and Asset Purchaser.  This Agreement sets forth the terms and conditions under
which NEP will transfer to Asset Purchaser the benefits, rights, and
privileges associated with the Commitments and Asset Purchaser will undertake
the payment obligations associated with the Commitments, except for NEP's
rights and obligations under the NEP Facilities Support Agreement and except
that regarding NEP's right to designate a representative to serve on the
Advisory Committee provided for in Section 6 of the Massachusetts Facilities
Support Agreement and Section 6 of the New Hampshire Facilities Support
Agreement (hereinafter "the Section 6 Right"), the Asset Purchaser shall have
an option to exercise the Section 6 Right.  With regard to the NEP Facilities
Support Agreement NEP will transfer to Asset Purchaser such benefits, rights,
and privileges, and only such benefits, rights, and privileges, as  NEP enjoys
as a Supporter under said Commitment, and Asset Purchaser will undertake such
obligations, and only such obligations, as NEP has undertaken as a Supporter
under said Commitment.  NEP will retain all of its rights and obligations
under the NEP Facilities Support Agreement as owner and operator of the
facilities that are the subject of said agreement.  NEP and Asset Purchaser
desire said transfer and undertaking to occur concurrently with the sale of
NEP's generation business to Asset Purchaser pursuant to the Asset Purchase
Agreement.  

1.   The Commitments are incorporated into this Agreement by reference.  A
     Commitment shall be automatically deleted from the Commitments
     incorporated in this Agreement without further action by the parties 
     (I) on the effective date of any Novation (defined in Section as 7,
     below), (ii) upon the expiration of a Commitment pursuant to its terms,
     or (iii) upon the termination of a Commitment pursuant to the written
     agreement of the parties thereto.

2.   This Agreement shall become effective on the Effective Date (as defined
     in Section 12) and shall remain in effect until Asset Purchaser has made
     payment to NEP of amounts owed pursuant to Section 4 of this Agreement
     and NEP has made payment to Asset Purchaser of any amounts owed pursuant
     to Section 3 or 4 of this Agreement for the last month in which a
     Commitment remains incorporated in this Agreement.

     (a)  Commencing as of the Effective Date, and terminating upon the
          termination of the Use Agreement, pursuant to section 6 of said
          Agreement, NEP transfers to Asset Purchaser the right to use all
          of NEP's Percentage Interest in the Transfer Capability of the
          Interconnection.  Such transfer shall be subject to the conditions
          set forth in section 6 of said Agreement.

     (b)  Asset Purchaser agrees that, to the extent it elects not to use a
          portion of the Transfer Capability transferred under subsection
          (a) of this section, Asset Purchase shall so notify NEP in
          writing, and NEP may make such Transfer Capability available under
          NEP's open access transmission tariff on file with the Federal
          Energy Regulatory Commission, and Asset Purchaser agrees to
          provide NEP with all information that NEP reasonably requests for
          the purpose of calculating the Annual Opportunity Cost Charge in
          Attachment Q, Exhibit 2 of the tariff to each Customer that uses a
          portion of the Transfer Capability.

     (c)  Commencing as of the Effective Date, NEP agrees that it will
          provide to Asset Purchaser all benefits accruing to NEP under each
          of the Commitments, except for the NEP Facilities Support
          Agreement, and that Asset Purchaser may exercise all rights and
          privileges of NEP under each of the Commitments; provided,
          however, that NEP shall retain the Section 6 Right subject to
          Asset Purchaser's option, exercisable in Asset Purchaser's sole
          discretion, to direct NEP to transfer to it the Section 6 Right. 
          Commencing as of the Effective Date, NEP agrees that, if and to
          the extent Asset Purchaser does not enjoy the rights of NEPOOL
          members under the Interconnection Agreement, NEP will provide to
          Asset Purchaser all benefits accruing to NEP under the
          Interconnection Agreement, and that Asset Purchaser may exercise
          all rights and privileges of NEP under the Interconnection
          Agreement, and that Asset Purchaser may exercise all rights and
          privileges of NEP under the Interconnection Agreement and the
          Interconnection Agreement shall be deemed to be a "Commitment"
          under this Agreement.  Commencing as of the Effective Date, NEP
          agrees that, if and to the extent Asset Purchaser does not enjoy
          the rights of NEPOOL members under the Energy Banking Agreement,
          NEP will provide to Asset Purchaser all benefits accruing to NEP
          under the Energy Banking Agreement, and that Asset Purchaser may
          exercise all rights and privileges of NEP under the Energy Banking
          Agreement and the Energy Banking Agreement shall be deemed to be a
          "Commitment" under this Agreement. 

     (d)  Commencing as of the Effective Date, NEP agrees that it will
          provide Asset Purchaser such benefits accruing to NEP under the
          NEP Facilities Support Agreement, and only such benefits, as NEP
          enjoys jointly with the other Supporters of the NEP Facilities
          Support Agreement and that Asset Purchaser may exercise such
          rights and privileges of NEP under the NEP Facilities Support
          Agreement, and only such rights and privileges, as NEP enjoys
          jointly with the other Supporters of the NEP Facilities Support
          Agreement.

     (e)  Commencing as of the Effective Date, Asset Purchaser agrees to
          maintain a billing settlement account at NEPOOL. The benefits and
          obligations relating to the NEPOOL settlement process that are
          being transferred under this Agreement, including but not limited
          to capability responsibility, shall be reflected in the Asset
          Purchaser's settlement account.

4.   Commencing as of the month following the Effective Date, Asset Purchaser
     agrees to pay to NEP (unless mutually agreeable arrangements are in
     place for Asset Purchaser to make direct payments under a Commitment)
     each month all amounts properly due for the preceding month, under each
     Commitment that remained incorporated in the Agreement during the
     previous month, from NEP to any party to such Commitment, including such
     amounts for which NEP is responsible solely as a Supporter, and not as
     owner and/or operator, under the NEP Facilities Support Agreement,
     except that during the first month following the Effective Date, Asset
     Purchaser shall pay to NEP the amount described in subsection (b) of
     this section.  The amounts properly due for the preceding month shall
     include any charges to NEP associated with goods or services provided
     pursuant to the Commitments in months prior to the preceding month but
     subsequent to the Effective Date, including billing adjustments and
     true-ups, any charges or costs resulting from regulatory or court
     orders, and any associated interest, but specifically excluding any
     general and administrative costs incurred by NEP in administering
     Attachment Q of NEP's open access transmission tariff, and shall be
     increased by any costs incurred by NEP or reduced by any revenues
     received by NEP, both associated with the sale of Transfer Capability
     under section 3(b).  Asset Purchaser's rights to audit NEP's bills shall
     be governed by NEP's open access transmission tariff.  Asset Purchaser
     shall make  payment under this section by wire transfer of immediately
     available funds at least one business day before such payment is due by

     NEP under each Commitment as to allow NEP to make timely payment under
     such Commitment.  In turn, each month NEP agrees to timely pay all
     amounts due under each Commitment, which includes the amount NEP
     receives from Asset Purchaser in connection with such Commitment.

     (a)  During the first month following the Effective Date, Asset
          Purchaser agrees to pay to NEP a portion of all amounts properly
          due for the preceding month, under each Commitment that remained
          incorporated in the Agreement during the previous month, from NEP
          to any party to  such Commitment, including such amounts for which
          NEP is responsible as a Supporter under the NEP Facilities Support
          Agreement.  Such portion shall be determined according to the
          ratio of the number of days in the month for which Asset Purchaser
          has a payment obligation under this Agreement to the total number
          of days in the month. 

     (b)  Upon and after the Effective Date, NEP shall notify Asset
          Purchaser within a reasonable time of any and all amounts which
          are then or thereafter received, under each Commitment, by NEP
          from any other party to such Commitments, except for payments
          received by NEP as owner and operator of the facilities that are
          the subject of the NEP Facilities Support Agreement.  Such amounts
          shall include, without limitation, any aggregate differential
          balances under any Commitment and the benefit of and proceeds from
          any security deposits, letters of credit or other similar
          instruments or accounts established for the benefit of NEP by such
          other party.  At Asset Purchaser's direction, NEP shall pay such
          amount to Asset Purchaser or  irrevocably and unconditionally
          assign and thereafter hold for the benefit of and/or credit to
          Asset Purchaser against payments due from it to NEP under Section
          4 hereof or at the termination of this Agreement.  Such amount
          shall exclude any credits or refunds received by NEP after the
          Effective Date which relate to billing errors or reconciliations
          of pre-Effective Date bills, and any amounts paid by such other
          party to NEP with respect to disputes arising before the Effective
          Date that are attributable to a period prior to the Effective
          Date.

5.   Effective as of the Effective Date, NEP hereby irrevocably and
     unconditionally appoints Asset Purchaser as its representative and agent
     for all purposes under each Commitment except for the NEP Facilities
     Support Agreement and except for NEP's Section 6 Right, subject to the
     Asset Purchaser's exercise of the option described in Section 3(c). 
     Effective as of the Effective Date, NEP hereby further irrevocably and
     unconditionally appoints Asset Purchaser as its representative and agent
     for any actions, and only such actions, that might be taken by NEP as a
     Supporter under the NEP Facilities Support Agreement.  Asset Purchaser
     is hereby authorized under such appointments to take all actions that
     NEP may lawfully take under such Commitments without further approval by
     NEP, including, without limitation, the following:  with respect to all
     matters arising under such Commitments, deal directly with the other
     parties to such Commitment, the New England Power Pool (NEPOOL), the
     Independent System Operator (as designated under the Restated NEPOOL
     Agreement as filed with the Federal Energy Regulatory Commission on
     December 31, 1996, and as amended from time to time), other transporters
     of electric energy, federal, state and local governmental authorities,
     and any other persons; act on NEP's behalf in the prosecution or
     defense, as the case may be, of any rights or liabilities arising under
     such Commitments; monitor the parties' performance under the
     Commitments; review and audit all bills and related documentation
     rendered  pursuant to the Commitments; and on NEP's behalf enter into
     amendments to such Commitments of any nature; provided, however Asset
     Purchaser shall not (i) amend any Commitment in a manner that affects
     NEP's rights or obligations under such Commitment prior to the Effective
     Date; (ii) amend any Commitment to extend the term thereof or increase
     NEP's obligations thereunder without NEP's consent, which shall not be
     unreasonably withheld and provided, further, that Asset Purchaser need

     not seek NEP's consent for amendments, extensions, or increases in NEP
     obligations if (i) the net present value of any increase on NEP
     obligations created thereby is less than five million dollars
     ($5,000,000) and (ii) Asset Purchaser shall have attained and maintained
     (A) "net worth," or "consolidated net worth," if applicable, as
     determined in accordance with U.S. generally accepted accounting
     principles and reflected in an audited balance sheet (or consolidated
     balance sheet, if applicable) ("Net Worth") at least equal to
     $500,000,000, and (B) an Investment Grade Rating, as defined below.  For
     purposes hereof, "Investment Grade Rating" means either (i) and S&P
     Credit Rating (as defined below) of BBB or above or (ii) a Moody's
     Credit Rating (as defined below) of Baa2 or above.  "S&P Credit Rating"
     shall mean the rating assigned by Standard & Poor's Ratings Group
     ("S&P") to the senior unsecured long-term debt of the Asset Purchaser
     (or, in the event that none of the Asset Purchaser's senior unsecured
     debt is rated by S&P, the Asset Purchaser's implied senior unsecured
     debt rating), and "Moody's Credit Rating" shall mean the rating level
     assigned by Moody's Investor Service, Inc. ("Moody's") to the senior
     unsecured long-term debt of the Asset Purchaser (or, in the event that
     none of the Asset Purchaser's senior unsecured debt is rated by Moody's,
     the Asset Purchaser's implied senior unsecured debt rating).  Asset
     Purchaser shall have the right to delegate to its affiliates or third
     parties any of its responsibilities under this Section 5.  NEP hereby
     agrees to provide and deliver to Asset Purchaser all information which
     NEP now has or hereafter acquires or to which it is entitled with
     respect to each Commitment and Asset Purchaser hereby agrees with
     respect to such information to be subject to any confidentiality
     provisions of such Commitment  and any restrictions on the dissemination
     of such information as are required by the Federal Energy Regulatory
     Commission.  NEP also agrees to participate at Asset Purchaser's request
     and under Asset Purchaser's direction in any governmental proceeding
     with respect to the Commitments or this Agreement.  Notwithstanding any
     provision to the contrary in this section, NEP shall have the right, and
     nothing in this Agreement shall limit NEP's right, to take a position on
     its own behalf and to submit testimony, make filings, and otherwise
     assert and defend such position in connection with any matter or
     proceeding concerning the  recovery of costs  associated with any
     Commitment in NEP's transmission rates.  Neither of the parties shall
     institute proceedings concerning this Agreement under sections 205 or
     206 of the Federal Power Act without the consent of the other party,
     which consent shall not be unreasonably withheld.

     (a)  NEP agrees not to agree to any amendment to, termination of,  or
          waiver of rights under a Commitment other than the NEP Facilities
          Support Agreement without Asset Purchaser's consent, which Asset
          Purchaser may grant or withhold in its sole discretion.  NEP will
          not take any actions inconsistent with the provisions of Section
          5.

6.   NEP will indemnify, defend and hold harmless the Asset Purchaser from
     and against any and all claims, demands or suits (by any person),
     losses, liabilities, damages (excluding consequential or special
     damages), obligations, payments, costs and expenses (including, without
     limitation, the costs and expenses of any and all actions, suits,
     proceedings, assessments, judgments, settlements, and compromises
     relating thereto and reasonable attorneys' fees and reasonable
     disbursements in connection therewith) to the extent the foregoing are
     not covered by insurance (each, an "Indemnifiable Loss"), asserted
     against or suffered by Asset Purchaser relating to, resulting from or
     arising out of any payment obligation of NEP resulting from or contained
     in this Agreement or any obligation of NEP for any acts or omissions
     under the Commitments incurred prior to the Effective Date.  For purpose
     hereof NEP's and Asset Purchaser's administrative costs incurred in
     administering the Commitments and performing their obligations under
     this Agreement shall not be an Indemnifiable Loss.  For purposes hereof,
     any failure of NEP to perform any act required to be performed by it
     under a Commitment (other than as owner/operator under the NEP

     Facilities Support Agreement) which increases the amounts payable by
     Asset Purchaser under Section 4(a) hereof shall be entitled to
     indemnification hereunder.

     (a)  Asset Purchaser will indemnify, defend and hold harmless NEP from
          and against any and all Indemnifiable Losses asserted against or
          suffered by NEP relating to, resulting from or arising out of any
          payment obligation of, or exercise of rights as NEP's agent by,
          Asset Purchaser resulting from or contained in this Agreement.

     (b)  Any person entitled to receive indemnification under this
          Agreement (an "Indemnitee") having a claim under these
          indemnification provisions shall make a good faith effort to
          recover all losses, damages, costs and expenses from insurers of
          such Indemnitee under applicable insurance policies so as to
          reduce the amount of any Indemnifiable Loss hereunder.  The amount
          of any Indemnifiable Loss shall be reduced (i) to the extent that
          Indemnitee receives any insurance proceeds with respect to an
          Indemnifiable Loss and (ii) to take into account any net Tax
          benefit recognized by the Indemnitee arising from the recognition
          of the Indemnifiable Loss and any payment actually received with
          respect to an Indemnifiable Loss.

     (c)  The expiration, termination or extinguishment of any covenant or
          agreement shall not affect the parties' obligations under this
          Section 6 if the Indemnitee provided to the person who is required
          to provide indemnification under this Agreement (the "Indemnifying
          Party") with proper notice of the claim or event for which
          indemnification is sought prior to such expiration, termination or
          extinguishment.

     (d)  The rights and remedies of NEP and Asset Purchaser under this
          Section 6 are exclusive and in lieu of any and all other rights
          and remedies which NEP and Asset Purchaser may have under this
          Agreement or otherwise for monetary relief with respect to any
          payment obligation resulting from this Agreement.

     (e)  NEP and Asset Purchaser each agree that, notwithstanding any
          provisions in this Agreement to the contrary, all parties to this
          Agreement retain their remedies at law or in equity with respect
          to willful or intentional breaches of this Agreement.

     (f)  If any Indemnitee receives notice of the assertion of any claim or
          of the commencement of any claim, action, or proceeding made or
          brought by any person who is not a party to this Agreement or any
          affiliate of a party to this Agreement (a "Third Party Claim")
          with respect to which indemnification is to be sought from an
          Indemnifying Party, the Indemnitee will give such Indemnifying
          Party reasonably prompt written notice thereof, but in any event
          not later than ten (10) calendar days after the Indemnitee's
          receipt of notice of such Third Party Claim.  Such notice shall
          describe the nature of the Third Party Claim in reasonable detail
          and will indicate the estimated amount, if practicable, of the
          Indemnifiable Loss that has been or may be sustained by the
          Indemnitee.  The Indemnifying Party will have the right to
          participate in or, by giving written notice to the Indemnitee, to
          elect to assume the defense of any Third Party Claim at such
          Indemnifying Party's own expense and by such Indemnifying Party's
          own counsel, and the Indemnitee will cooperate in good faith in
          such defense at such Indemnitee's own expense.

     (g)  If within ten (10) calendar days after an Indemnitee provides
          written notice to the Indemnifying Party of any Third Party Claim
          the Indemnitee receives written notice from the Indemnifying Party
          that such Indemnifying Party has elected to assume the defense of
          such Third Party Claim as provided in the last sentence of clause
          (g), the Indemnifying Party will not be liable for any legal

          expenses subsequently incurred by the Indemnitee in connection
          with the defense thereof; provided, however, that if the
          Indemnifying Party fails to take reasonable steps necessary to
          defend diligently such Third Party Claim within twenty (20)
          calendar days after receiving notice from the Indemnitee that the
          Indemnitee believes the Indemnifying Party has failed to take such
          steps, the Indemnitee may assume its own defense, and the
          Indemnifying Party will be liable for all reasonable expenses
          thereof.  Without the prior written consent of the Indemnitee, the
          Indemnifying Party will not enter into any settlement of any Third
          Party Claim 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 a
          firm offer is made to settle a 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 Indemnifying Party
          desires to accept and agree to such offer, the Indemnifying Party
          will give written notice to the Indemnitee to that effect.  If the
          Indemnitee fails to consent to such firm offer within ten (10)
          calendar 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 Indemnifying Party as to such
          Third Party Claim will 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.

     (h)  Any claim by an Indemnitee on account of an Indemnifiable Loss
          which does not result from a Third Party Claim (a "Direct Claim")
          will be asserted by giving the Indemnifying Party reasonably
          prompt written notice thereof, stating the nature of such claim in
          reasonable detail and indicating the estimated amount, if
          practicable, but in any event not later than ten (10) calendar
          days after the Indemnitee becomes aware of such Direct Claim, and
          the Indemnifying Party will have a period of thirty (30) calendar
          days within which to respond to such Direct Claim.  If the
          Indemnifying Party does not respond within such thirty (30)
          calendar day period, the Indemnifying Party will be deemed to have
          accepted such claim.  If the Indemnifying Party rejects such
          claim, the Indemnitee will be free to seek enforcement of its
          rights to indemnification under this Agreement.

     (i)  If the amount of any Indemnifiable Loss, at any time subsequent to
          the making of an indemnity payment in respect thereof, is reduced
          by recovery, settlement or otherwise under or pursuant to any
          insurance coverage, or pursuant to any claim, recovery, settlement
          or payment by or against any other entity, the amount of such
          reduction, less any costs, expenses or premiums incurred in
          connection therewith (together with interest thereon from the date
          of payment thereof at the prime rate then in effect of the Bank of
          Boston), will promptly be repaid by the Indemnitee to the
          Indemnifying Party.  Upon making any indemnity payment, the
          Indemnifying Party will, to the extent of such indemnity payment,
          be subrogated to all rights of the Indemnitee against any third
          party in respect of the Indemnifiable Loss to which the indemnity
          payment relates; provided, however, that (i) the Indemnifying
          Party will then be in compliance with its obligations under this
          Agreement in respect of such Indemnifiable Lose and (ii) until the
          Indemnitee recovers full payment of its Indemnifiable Loss, any
          and all claims of the Indemnifying Party against any such third
          party on account of said indemnity payment is hereby made
          expressly subordinated and subjected in right of payment to the
          Indemnitee's rights against such third party.  Without limiting
          the generality or effect of any other provision hereof, each such
          Indemnitee and Indemnifying Party will duly execute upon request
          all instruments reasonably necessary to evidence and perfect the
          above-described subrogation and subordination rights, and

          otherwise cooperate in the prosecution of such claims at the
          direction of the Indemnifying Party.  Nothing in this clause (j)
          shall be construed to require any party hereto to obtain or
          maintain any insurance coverage.

     (j)  A failure to give timely notice as provided herein will not affect
          the rights or obligations of any party hereunder except if, and
          only to the extent that, as a result of such failure, the party
          which was entitled to receive such notice was actually prejudiced
          as a result of such failure.

7.   NEP and Asset Purchaser agree to work cooperatively and use all
     reasonable efforts to amend each Commitment and assign each such amended
     Commitment to Asset Purchaser so that NEP will be released of all
     further liabilities and obligations under the Commitment and Asset
     Purchaser will be directly in contract with the other parties to the
     Commitment (a "Novation"), except that, with regard to the NEP
     Facilities Support Agreement, such assignment will be limited to the
     rights and obligations of NEP as a Supporter under the NEP Facilities
     Support Agreement and except that NEP shall retain its Section 6 Right,
     subject to Asset Purchaser's option, exercisable in Asset Purchaser's
     sole discretion, to direct NEP to assign its Section 6 Right, in which
     event there shall be a Novation of the Section 6 Right.  Any such
     Novation shall include all modifications necessary to reflect the
     substitution of Asset Purchaser for NEP as the party under the
     Commitment and to properly describe interconnection, delivery point and
     transmission system references and obligations in the Commitment.  It is
     intended by the parties that all such Novations preserve the economic
     benefit and other rights of the Commitment to the Asset Purchaser
     without increasing the Asset Purchaser's obligations under the
     Commitment while continuing to afford to NEP the protections for its
     transmission system embodied in the Commitment.  NEP and Asset Purchaser
     agree to execute all agreements and documents reasonably required by the
     other in connection with all such Novations.

8.   This Agreement and all rights, obligations, and performances of the
     parties hereunder, are subject to all applicable Federal and state laws,
     and to all duly promulgated orders and other duly authorized action of
     governmental authority having jurisdiction.

9.   Except as otherwise set forth in Section 5 hereof, this Agreement and
     all of the provisions hereof shall be binding upon and inure to the
     benefit of the parties hereto and their respective successors and
     permitted assigns, but neither this Agreement nor any of the rights,
     interests or obligations hereunder shall be assigned by any party
     hereto, including by operation of law without the prior written consent
     of the other party, not to be unreasonably withheld, nor is this
     Agreement intended to confer upon any other person except the parties
     hereto any rights or remedies hereunder.  Notwithstanding the foregoing,
     (i) the Asset Purchaser may assign all of its rights and obligations
     hereunder to any wholly owned Subsidiary (direct or indirect) of PG&E
     Corporation and upon NEP's receipt of notice from Asset Purchaser of any
     such assignment, the Asset Purchaser will be released from all
     liabilities and obligations hereunder, accrued and unaccrued, such
     assignee will be deemed to have assumed, ratified, agreed to be bound by
     and perform all such liabilities and obligations, and all references
     herein to Asset Purchaser shall thereafter be deemed references to such
     assignee, in each case without the necessity for further act or evidence
     by the parties hereto or such assignee; provided, however, that no such
     assignment and assumption shall release the Asset Purchaser from its
     liabilities and obligations hereunder unless the assignee shall have
     acquired all or substantially all of the Asset Purchaser's assets;
     provided, further, however, that no such assignment and assumption shall
     relieve or in any way discharge PG&E Corporation from the performance of
     its duties and obligations under the Guaranty dated August 5, 1997,
     executed by PG&E Corporation for the purpose of financing or refinancing
     the Purchased Assets (as defined in the Asset Purchase Agreement); and

     (ii) the Asset Purchaser or its permitted assignee may assign, transfer,
     pledge or otherwise dispose of its rights and interests hereunder to a
     trustee or lending institution(s) for the purpose of financing or
     refinancing the Purchased Assets (as defined in the Asset Purchase
     Agreement), including upon or pursuant to the exercise of remedies under
     a financing or refinancing, or by way of assignments, transfers,
     conveyances or dispositions in lieu thereof; provided, however, that no
     such assignment or disposition shall relieve or in any way discharge the
     Asset Purchaser or such assignee from the performance of its duties and
     obligations under this Agreement.  NEP agrees to execute and deliver
     such documents as may be reasonably necessary to accomplish any such
     assignment, transfer, conveyance, pledge or disposition of rights
     hereunder so long as NEP's rights under this Agreement are not thereby
     altered, amended, diminished or otherwise impaired.

10.  This Agreement, the Asset Purchase Agreement and any other agreement
     entered into by the parties pursuant to the Asset Purchase Agreement
     constitute the entire agreement between the parties and supersede all
     previous offers, negotiations, discussions, communications and
     correspondence.  This Agreement may be amended only by a written
     agreement signed by the parties.  This Agreement is not intended to
     confer upon any other person except the parties hereto any rights or
     remedies.  The interpretation and performance of this Agreement shall be
     according to and controlled by the Federal Power Act and the laws of The
     Commonwealth of Massachusetts (regardless of the laws that might
     otherwise govern under applicable Massachusetts principles of conflicts
     of laws).

11.  All payments required under this Agreement shall be paid in cash by
     federal or other wire transfer of immediately available funds to an
     account designated by the party to receive such payment.

12.  This Agreement shall be of no force and effect until the Effective Date. 
     If the Asset Purchase Agreement shall have been terminated before the
     occurrence of the Closing Date (as defined in the Asset Purchase
     Agreement), this Agreement shall, without any action of the parties
     hereto, terminate as of the time of the termination of the Asset
     Purchase Agreement.  As used in this Agreement, "Effective Date" shall
     mean the Closing Date (as defined in the Asset Purchase Agreement).

     IN WITNESS WHEREOF, the parties have caused their duly authorized
representatives to execute this Agreement on their behalf as of the date first
above written.
