THIS MASTER AGREEMENT is made the 30th day of March 1990 and becomes effective
on the 31st day of March 1990 BETWEEN:

(1)   THE NATIONAL GRID COMPANY PLC a company registered in England with number
      2366977 whose registered office is at National Grid House, Sumner Street,
      London SEI 9JU ("NGC", which expression shall include its successors
      and/or permitted assigns) and whose address, telex and facsimile numbers
      for notices are set out in Schedule 1; and

(2)   THE PERSONS whose names, registered numbers, registered offices, and
      addresses, telex and facsimile numbers for notices are set out in Schedule
      1 (each a "User", which expression shall include its successors and/or
      permitted assigns)

WHEREAS:

      This Master Agreement has the following principal purposes:

      (i)   to establish contractual framework between NGC and all Users
            pursuant to which Supplemental Agreements will from time to time be
            made which will provide for, amongst other things:

            (a)   connection of a User's Equipment at a Connection Site to the
                  NGC Transmission System;

            (b)   the use by a User of the NGC Transmission System in connection
                  with the generation and/or transmission of electricity;

            (c)   the payment to NGC of Connection Charges and/or Use of System
                  Charges; and

      (ii)  to provide for the enforcement of the Grid Code.

 
NOW IT IS HEREBY AGREED AS FOLLOWS:

1.    INTERPRETATION AND CONSTRUCTION

1.1   In this Agreement and in each Supplemental Agreement the words and
      expressions defined in Schedule 2 shall, unless the subject matter or
      context otherwise requires or is inconsistent therewith, apply.

1.2   In the event of any inconsistency between the provisions of any
      Supplemental Agreement and this Agreement, the provisions of the
      Supplemental Agreement shall prevail in relation to the Connection Site
      which is the subject thereof to the extent that the rights and obligations
      of Users not party to that Supplemental Agreement are not affected.

1.3   If in order to comply with any obligation in this Agreement or any
      Supplemental Agreement any Party is under a duty to obtain the consent or
      approval (including any statutory licence or permission) ("the Consent")
      of a third party (or the consent of another Party to this Agreement) such
      obligation shall be deemed to be subject to the obtaining of such Consent
      which the Party requiring the consent shall use its reasonable endeavors
      to obtain including (if there are reasonable grounds therefor) pursuing
      any appeal in order to obtain such Consent.

      1.3.1. If such Consent is required from any Party to this Agreement then
             such Party shall grant such Consent unless it is unable to do so or
             it would be unlawful for it to do so provided that such grant by
             such Party may be made subject to such reasonable conditions as 
             such Party shall reasonably determine.

      1.3.2. For the avoidance of doubt if the Party who is under a duty to
             obtain such Consent fails to obtain such Consent having complied
             with this Clause 1.3 the obligation on that Party (in relation to
             which such Consent is required) shall cease.

            account in its assessment of the circumstances and anticipated
            breach referred to above; and

      (ii)  use its best endeavors to comply with the relevant provision in a
            manner which will not cause the Nuclear Generator to breach any of
            the matters specified in Sub-Clause 5.4 below.

5.2   Sub-Clauses 5.1 and 5.3 shall not apply in relation to the provisions of
      SDC1, SDC2 and SDC3 of the Grid Code which will apply with full force and
      effect notwithstanding the occurrence of the circumstances referred to in
      Sub-Clause 5.1(a) (including those provisions specified in Sub-Clause 5.4
      which relate to Safety of Personnel and Plant).

5.3   Save as provided in Sub-Clause 5.2 above notwithstanding anything this
      Agreement, the Nuclear Generator shall be entitled upon giving reasonable
      notice


                                       8

 
      to all affected Parties to require any Party to take any reasonable and
      proper action whatsoever to the extent necessary in order to comply with
      (or avert an anticipated breach of) any of the matters specified in
      Sub-Clause 5.4 below.

5.4   The matters referred to in Sub-Clauses 5.1 and 5.3 above are any covenant,
      agreement, restriction, stipulation, instruction, provision, condition or
      notice contained, or referred to, in a licence for the time being in
      force, granted in accordance with the Notice Installation Act 1965 (or

6.    PRINCIPLES OF OWNERSHIP

6.1   Ownership - electrical boundaries

      Subject to the Transfer Scheme or any contrary agreement in this
      Agreement, any Supplemental Agreement or elsewhere the division of
      ownership of Plant and Apparatus shall be at the electrical boundary, such
      boundary to be determined in accordance with the following principles:

      (i)   In relation to Plant and Apparatus located between the NGC
            Transmission System and a Power Station, the electrical boundary is
            at the busbar clamp on the busbar side of the busbar isolators on
            Generators and Power Station transformer circuits;

      (ii)  save as specified in Clause 6.1(iii) below, in relation to Plant and
            Apparatus located between the NGC Transmission System and a
            Distribution System, the electrical boundary is at the busbar clamp
            in the busbar side of the Distribution System voltage busbar
            selector isolator(s) of the NGC Transmission System circuit or, if a
            conventional busbar does not exist, an equivalent isolator. If no
            isolator exists an agreed bolted connection at or adjacent to the
            tee point shall be deemed to be an isolator for these purposes;

      (iii) in relation to Plant and Apparatus located between the NGC
            Transmission System and a Distribution System and owned by NGC but
            designed for a voltage of 132KV or below, the electrical boundary is
            at the busbar clamp on the busbar side of the busbar selector
            isolator on the Distribution System circuit or, if a conventional
            busbar does not exist, an equivalent isolator. If no isolator
            exists, an agreed bolted connection at or adjacent to the tee point
            shall be deemed to be an isolator for these purposes; and

      (iv)  in the case of a metal clad switchgear bay the electrical boundary
            will be the equivalent of those specified in this Clause 6.1 save
            that:


                                       10

 
            (a)   for rack out switchgear, the electrical boundary will be at
                  the busbar shutters;

            (b)   for SF6 switchgear, the electrical boundary will be at the gas
                  zone separators on the busbar side of the busbar selection
                  devices.

6.2   If a User wants to use transformers of specialised design for unusual load
      characteristics at the electrical boundary, NGC shall own such
      transformers but the User shall pay NGC for the proper and reasonable
      additional cost thereof as identified by NGC in the Offer covering such
      transformers. In this Sub-Clause 6.2 "unusual load characteristics" means
      loads which have characteristics which are significantly different from
      those of the normal range of domestic, commercial and industrial loads
      (including loads which vary considerably in duration or magnitude).

6.3   For the avoidance of doubt nothing in this Clause 6 shall effect any
      transfer of ownership in any Plant or Apparatus.

7.    METERING

7.1   Each User consents to NGC having access to and copies of all meter
      readings taken from Energy Metering Equipment pursuant to the Pooling and
      Settlement Agreement in any Financial Year for the purposes of calculating
      Connection Charges and Use of System Charges due from Users or for the
      purpose of operating the NGC Transmission System. Such access and copies
      shall be obtained from the Settlement System Administrator appointed under
      the Pooling and Settlement Agreement from time to time provided always
      that if the Settlement System Administrator fails to provide such access
      and copies at NGC's request the User shall supply any such meter readings
      in the possession of the User direct to NGC.


                                       11

 
7.2   The relationship between the Parties hereto with respect to Energy
      Metering Equipment shall be regulated by Part XV of the Pooling and
      Settlement Agreement.

7.3   In respect of Operational Metering Equipment owned by the Party and in
      respect of which access and rights to deal with such Operational Metering
      Equipment are not set down in any other document the Parties shall grant
      each other such access and the rights as are reasonably necessary to
      enable them to perform their obligations under this Agreement and the Grid
      Code upon presentation of a suitable indemnity and the Parties shall take
      such action as may be necessary to regularise the position forthwith
      thereafter.

8.    NGC OBLIGATIONS

8.1   NGC agrees with each User to make available, plan, develop, operate and
      maintain the NGC Transmission System in accordance with the NGC
      Transmission Licence and with the Grid Code subject to any Derogations
      from time to time.

9.    COMPLIANCE WITH THE GRID CODE/DISTRIBUTION CODE

9.1   Subject to Sub-Clause 9.3 each Party agrees with each other Party to be
      bound by and to comply in all respects with the provisions of the Grid
      Code in so far as applicable to that Party.

9.2   Subject to Sub-Clause 9.3 each Party agrees with each other Party to be
      bound by and to comply in all respects with the provisions of the relevant
      Distribution Code(s) in so far as applicable to that Party except as may
      be otherwise provided in any agreement for connection to a Distribution
      System.

9.3   Neither NGC nor a User need comply with the Grid Code or any relevant
      Distribution Code(s) to the extent (if any) that:


                                       12

 
      (i)   either the Director has issued directions relieving NGC or that User
            from the obligation under its respective licence to comply with the
            Licence Standards, the Grid code or any relevant Distribution
            Code(s) in respect of such parts of the Grid Code or any relevant
            Distribution Code(s) respectively as may be specified in those
            directions or to the extent that NGC and a User which does not have
            a Licence under the Act can and have so agreed in any Supplemental
            Agreement in relation to any Connection Site or New Connection Site
            and/or Derogated Plant; or

      (ii)  (in the case of a User) the Grid Code relates to the provision by
            that User of any Ancillary Services unless there is an Ancillary
            Services Agreement in force between that User and NGC for the
            payment by NGC for such Ancillary Services; or

      (iii) (in the case of NGC) the Grid Code imposes any obligation on NGC to
            make available Additional Scheduling Data (as defined in the Grid
            code) before 31st December 1990.

9.4   In this Sub-Clause 9.4 the following expressions shall bear the following
      meanings:

      "Required Standard"       In relation to an item of Derogated Plant, the
                                respective standard required of that item (which
                                shall not exceed that required by the Grid code
                                or the Licence Standards, as the case may be) as
                                specified in or pursuant to the relevant
                                Derogation;

      "Back                     Stop Date" in relation to an item of Derogated
                                Plant, the date by which it is to attain its
                                Required Standard, as specified in or pursuant
                                to the relevant Derogation.


                                       13

 
      Each User undertakes to NGC and NGC undertakes to each User to use all
      reasonable endeavours to carry out such works as are necessary to ensure
      that each item of Derogated Plant owned or operated by that User or NGC
      (as appropriate) is brought up to the Required Standard applicable to it
      no later than the Back stop Date applicable to it.

9.5   The terms and provisions of the Fuel Security Code shall prevail to the
      extent that they are inconsistent with the Grid code or any Distribution
      code and the Parties' obligations under this Agreement shall be construed
      accordingly.

10.   MODIFICATIONS

10.1  No modification may be made by or on behalf of a User or NGC otherwise
      than in accordance with the provisions of this Clause 10.

      proceed according to the terms of the Supplemental Agreement entered into
      consequent upon acceptance of the Offer.

12.   GENERAL PROVISIONS CONCERNING MODIFICATIONS AND NEW CONNECTION SITES

12.1  subject to the payment of its Reasonable Charges, if any, as provided for
      in this Sub-Clause NGC undertakes to each User to provide all advice and
      assistance reasonably requested by that User to enable that User
      adequately to assess the


                                       16

 
      implications (including the feasibility) of making a Modification to the
      User's Equipment or the Users System (whether such Modification is to be
      made at the request of NGC or of the User) or of constructing a New
      Connection Site (including adequately assessing the feasibility of making
      any Connection Application or considering the terms of any Connection
      Offer). If the proposed Modification by the User is or may be required as
      a result of a Modification proposed by NGC then NGC shall provide such
      advice and assistance free of charge. If the proposed Modification is or
      may be proposed by the User or if the advice and assistance is in respect
      of a New connection Site NGC may charge the User Reasonable charges for
      such advice and assistance. The provisions of such advice and assistance
      shall be subject to any confidentiality obligations binding on NGC and
      that User.

12.2  When giving such advice and assistance NGC shall comply with Good Industry
      Practice.

12.3  NGC shall have no obligation to compensate any User (the "First User") for
      the cost or expense of any Modification required to be made by any User as
      a result of any NGC Modification under Sub-Clause 10.3.1. Where such NGC
      Modification is made as a result of the construction of a New Connection
      Site or a Modification for another User (the "Other User"), the Other User
      shall compensate the First User for the reasonable and proper cost and
      expense of any Modifications required to be made by the First User as a
      result of that NGC Modification. Such compensation shall be paid to the
      First User by the Other User within thirty days of production to the Other
      User of a receipted invoice (together with a detailed breakdown of such
      reasonable costs and expenses) for the expenditure which has been incurred
      by the First User.


                                       17

 
12.4  Modification Offers and Connection Offers conditional Upon other
      Modification Offers and Connection Offers

      If at the time of making any Offer or Modification Offer or Connection
      Offer to a User ("the Second Offer") there is an outstanding Modification
      Offer(s) or Connection Offer(s) to another User(s) ("the First Offer")
      which if accepted would affect the terms of the Second Offer NGC shall at
      the time of making the Second Offer.

      (i)   inform the recipient(s) of both the First Offer(s) and Second
            Offer(s) in writing that there is another Offer outstanding which
            might affect them; and

      (ii)  be entitled to make the First Offer(s) and Second Offer(s)
            conditional upon other outstanding Offers not having been or being
            accepted; and

      (iii) be entitled to vary the terms of either Offer if the other Offer is
            accepted first on the same procedures as those set out in Clauses
            10.2.2 to 10.2.4 or 11.2 to 11.4 inclusive as the case may be.

13.   ADDITIONAL PARTIES

13.1  The Parties shall admit as an additional party to this Master Agreement
      any person who accepts a Connection Offer from NGC or any new Embedded
      User (the "New Party") and who is not at the time already a Party. Such
      admission shall take effect by way of Accession Agreement prepared by NGC
      at the expense and cost of the New Party and to be executed by NGC for
      itself and on behalf of all other Parties. Upon execution of the Accession
      Agreement by NGC and the New Party and subject to the terms and conditions
      of that Accession Agreement, the New Party shall become a Party for all
      purposes of this Agreement.


                                       18

 
13.2  Each Party hereby authorises and instructs NGC to sign any such Accession
      Agreement on its behalf and undertakes not to withdraw, qualify or revoke
      any such authority or instruction at any time.

13.3  NGC shall promptly notify all Parties in writing that the New Party has
      become a Party.

14.   PAYMENT

14.1  NGC will invoice Users for Connection Charges and/or Use of System Charges
      due under each Supplemental Agreement in the following manner:

                  User with recourse to all appropriate measures and procedures)

            and in any such case within 28 days of this appointment the
            liquidator, receiver, administrative receiver, administrator,

      six months after the later of Deenergisation and the conclusion of the
      Disputes Resolution Procedure in favour of NGC, NGC may Disconnect all
      that User's Equipment at each Connection Site where the User's Equipment
      is connected and:

            Agreements to the purchaser thereof on condition that the purchaser
            if not already a User enters into an Accession Agreement with NGC
            under Clause 13 and confirms to NGC in


                                       26

 
            writing either that all of the technical or related conditions,
            data, information, operational issues or other matters specified in
            or pursuant to the relevant Supplemental Agreement(s) or Grid code
            by the User seeking the transfer will remain unchanged or, if any
            such matters are to be changed, the purchaser first notifies NGC in
            writing of such changes which NGC will consider promptly and in any
            event within 28 days of receiving notice of such change and until
            such consideration is complete the transfer shall not be effective.
            If having considered such changes NGC in its reasonable opinion does
            not consider the proposed changes reasonably satisfactory to NGC it
            shall consult with the User seeking to undertake such transfer and
            pending the outcome thereof to NGC's reasonable satisfaction the
            transfer shall not be effective provided always that the User may
            refer any dispute to the Disputes Resolution Procedure. such
            transfer shall become effective once the changes are reasonably
            satisfactory to NGC or have been determined to be so under the
            Disputes Resolution Procedure;

      (ii)  upon the disposal by a User of part of its business undertaking
            comprising User's Equipment at one or more Connection Sites that
            User shall have the right to transfer its rights and obligations
            under all relevant Supplemental Agreements to the purchaser thereof
            on condition that the purchaser (if not already a User) enters into
            an Accession Agreement with NGC under Clause 13 and confirms to NGC
            in writing either that all of the technical or related conditions,
            data, information, operational issues or other matters specified in
            or pursuant to the relevant Supplemental Agreement(s) or Grid Code
            by the User seeking the transfer will remain unchanged or, if any
            such matters are to be changed, the purchaser first notifies NGC in
            writing of such changes which NGC will consider promptly and in any


                                       27

 
            event within 28 days of receiving notice of such change and until
            such consideration is complete the assignment shall not be
            effective. If having considered such changes NGC in its reasonable
            opinion does not consider the proposed changes reasonably
            satisfactory to NGC it shall consult with the User seeking to
            undertake such transfer and pending the outcome thereof to NGC's
            reasonable satisfaction the transfer shall not be effective provided
            always that the User may refer any dispute to the Disputes
            Resolution Procedure. Such transfer shall become effective once the
            changes are reasonably satisfactory to NGC or have been determined
            to be so under the Disputes Resolution Procedure;

      (iii) a User may assign or charge its benefit under this Agreement and any
            Supplemental agreements in whole or in part by way of security.

      performance of any of its obligations or duties arising under this
      Agreement or any Supplemental Agreement including activities envisaged by
      the Grid Code without the prior consent of any other Party. The
      sub-contracting by a Party of the performance of any obligations or duties
      under this Agreement or any supplemental Agreement or of any activities
      envisaged by the Grid Code shall not relieve that party from liability for
      performance of such obligation or duty.

            Party's obligations

      shall be suspended for a period equal to the circumstance of Force Majeure
      provided that:

      (i)   the suspension of performance is of no greater scope and of no

      partial exercise of any such right, power, privilege or remedy shall not

                                       38

 
25.2  NGC and each User acknowledges that, because there has been insufficient
      time to discuss and agree the details of the Appendices to each
      Supplemental Agreement, those details may be inaccurate. Accordingly,

      (a)   each User and NGC undertake to discuss in good faith the correct
            identification of the details of each part of Appendix F of each
            Supplemental Agreement entered into between NGC and the User with a
            view to amending the same as necessary to reflect the correct
            position. To the extent that agreement on the correct position
            cannot be reached within 12 months after the date of that
            Supplemental Agreement the matter shall be referred to arbitration
            for determination in accordance with Clause 26 of this Agreement and
            such details shall be amended accordingly following such agreement
            or determination (as the case may be); and

      (b)   in relation to Appendix A of each Supplemental Agreement, NGC
            undertakes to establish a new asset register, specifying all Plant
            and Apparatus owned by NGC which is necessary to connect each User's
            Equipment to the NGC Transmission System at each Connection Site,
            during the course of the Financial Year ending 31st March 1991 in
            accordance with paragraph 2.2 of Appendix E to such Supplemental
            Agreement. Such new asset register shall, provided that NGC has
            complied with such paragraph 2.2, take effect from 1st April 1991.
            Following the establishment of such new asset register, each such
            Appendix A and any provisions of the relevant Supplemental Agreement
            which refer to it shall, to the extent appropriate, be amended
            accordingly.

26.   DISPUTE RESOLUTION

26.1  Save where expressly stated in this Agreement to the contrary and subject
      to any contrary provision of the Act, any License, or the Regulations, or
      the rights,


                                       39

 
      powers, duties and obligations of the Director or the Secretary of State
      under the Act, any License or otherwise howsoever, any dispute or
      difference of whatever nature howsoever arising under out of or in
      connection with this Agreement between any one or more Parties hereto
      shall be and is hereby referred to arbitration pursuant to the arbitration
      rules of the Electricity Supply Industry Arbitration Association in force
      from time to time.

26.2  Whatever the nationality, residence or domicile of any Party to this
      Agreement and wherever the dispute or difference or any part thereof arose
      the law of England shall be the proper law of any reference to arbitration
      hereunder and in particular (but not so a to derogate from the generality
      of the foregoing) the provisions of the Arbitration Acts 1950
      (notwithstanding anything in section 34 thereof) to 1979 shall apply to
      any such arbitration wherever the same or any part of it shall be
      conducted.

26.3  Subject always to Sub-Clause 26.6 below, if any tariff customer (as
      defined in Section 22(4) of the Electricity Act 1989) brings any legal
      proceedings in any court (as defined in the Rules of the Supreme Court
      1965 and in the County Courts Act 1984) against one or more persons, any
      of which is a Party to this Agreement (the "Defendant Party"), and the
      Defendant Party, and the Defendant Party wishes to make a Third Party
      Claim (as defined in Sub-Clause 26.5 below) against any other Party to
      this Agreement ("the Other Party") which would but for this Sub-Clause
      have been a dispute or difference referred to arbitration by virtue of
      Sub-Clause 26.1 above which shall not apply and in lieu of arbitration,
      the court in which the legal proceedings have been commenced shall hear
      and completely determine and adjudicate upon the legal proceedings and the
      Third Party Claim not only between the tariff customer and the Defendant
      Party but also between either or both of them and any Other Party whether
      by way of third party


                                       40

 
      proceedings (pursuant to the Rules of the Supreme Court 1965 or the County
      Court Rules 1881) or otherwise as may be ordered by the court.

26.4  Where a Defendant Party makes a Third Party Claim against any Other Party
      and such Other Party wishes to make a Third Party Claim against a further
      Party the provisions of Sub-Clause 26.3 above shall apply mutatis mutandis
      as if such Party had been the Defendant Party and similarly in relation to
      any such further Party.

26.5  For the purposes of this Clause 26 "Third Party Claim" shall mean:-

      (a)   any claim by a Defendant Party against any other Party (whether or
            not already a party to the legal proceedings) for any contribution
            or indemnity, or

      (b)   any claim by a Defendant Party against such an Other Party for any
            relief or remedy relating to or connected with the subject matter of
            the legal proceedings and substantially the same as some relief or
            remedy claimed by the tariff customer, or

      (c)   any requirement by a Defendant Party that any question or issue
            relating to or connected with the subject matter of the legal
            proceedings should be determined not only as between the tariff
            customer and the Defendant Party but also as between either or both
            of them and an Other Party (whether or not already a party to the
            legal proceedings).

26.6  Sub-Clause 26.3 above shall apply only if at the time the legal
      proceedings are commenced no arbitration has been commenced between the
      Defendant Party and an Other Party raising or involving the same or
      substantially the same issues as would be raised by or involved in the
      Third Party Claim. The tribunal in any arbitration which has been
      commenced prior to the commencement of legal proceedings shall determine
      the question in the event of dispute, whether the issues raised or
      involved are the same or substantially the same.


                                       41

 
27.   JURISDICTION

      exclusive jurisdiction to settle any disputes which may arise out of or in
      connection with this Agreement including the Grid Code and any
      Supplemental Agreement and that accordingly any suit, action or proceeding
      (together in this Clause 27 referred to as "Proceedings") arising out of
      or in connection with this Agreement and any Supplemental Agreement may be
      brought in such courts.

27.2  Each Party irrevocably waives any objection which it may have now or
      hereafter to the laying of the venue of any Proceedings in any such court
      as is referred to in this Clause 27 and any claim that any such
      Proceedings have been brought in an inconvenient forum and further
      irrevocably agrees that judgment in any Proceedings brought in the English
      courts shall be conclusive and binding upon such Party and may enforced in
      the courts of any other jurisdiction.

27.3  Each Party which is not incorporated in any part of England and Wales
      agrees that if it does not have, or shall cease to have, a place of
      business in England and Wales it will promptly appoint, and shall at all
      times maintain, a person in England and Wales irrevocably to accept
      service of process on its behalf in any Proceedings in England.

27.4  For the avoidance of doubt nothing contained in Sub-Clause 27.1 to 27.3
      above shall be taken as permitting a Party to commence Proceedings in the
      courts where this Agreement otherwise provides for Proceedings to be
      referred to arbitration.

28.   GOVERNING LAW

      This Agreement and each Supplemental Agreement shall be governed by and

      Competent Authority such invalidity, unenforceability or illegality shall
      not prejudice or affect the remaining provisions of this Agreement or any
      Supplemental Agreement which shall continue in full force and effect
      notwithstanding such invalidity, unenforceability or illegality.
