<PAGE>

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.

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
<PAGE>

            (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
<PAGE>

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
<PAGE>

      (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
<PAGE>

      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.

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
<PAGE>

      implications (including the feasibility) of making a Modification to the
      User's Equipment or the User's 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.

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:

      (i)   in the case of recurrent monthly charges other than the Energy
            related charges identified in Appendix D to the relevant
            Supplemental Agreement NGC shall despatch an invoice on or before
            the 15th day of the month for the charges due in relation to that

            undertaking it shall have the right to transfer its rights and
            obligations under this Agreement and 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


                                       26
<PAGE>

            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
<PAGE>

            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;

      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.

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
<PAGE>

      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 as 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
<PAGE>

      proceedings (pursuant to the Rules of the Supreme Court 1965 or the County
      Court Rules 1981) 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.

2.5      APPEAL TO DIRECTOR

         2.5.1    Where any TUG Party considers that any modification,
                  abrogation, amendment or suspension proposed to be made to any
                  provisions of the Agreement in respect of which the consent or
                  approval of a TUG Party is not required (pursuant to paragraph
                  2.2) would have a material adverse effect on its rights and
                  liabilities as a TUG Party as set out in this Schedule (the
                  "proposed change"), it shall have the right in the prescribed
                  time limits to refer the matter in writing to the Director
                  (such referral to be copied to NGC, each Party and each TUG
                  party) who shall determine, taking into account the views of
                  Parties, whether such proposed change has a material adverse
                  effect on the basis of TUG Parties as a group.  The Director
                  shall not have locus standi to consider perceived or actual
                  prejudice to an individual TUG Party. The Director's
                  determination shall be final and binding for all purposes.

         2.5.2    For the purposes of enabling a TUG Party to appeal to the
                  Director in accordance with the terms of paragraph 2.5.1, NGC
                  shall give all TUG Parties and the Director notice of the
                  proposed change at least 14 clear days prior to the
                  implementation of the proposed change in accordance with the
                  provisions of this Agreement.

         2.5.3    If an appeal to the Director against a proposed change is made
                  within 14 days after notification by NGC pursuant to paragraph
                  2.5.2, the change shall not come into effect until the
                  determination of the Director has been made in accordance with
                  the terms of paragraph 2.5.4 or paragraph 2.5.5 applies. If no
                  appeal is made within the said 14 days, the change shall come
                  into effect on the expiry of that period.

         2.5.4    The Director shall within 28 days of receipt of a referral
                  pursuant to paragraph 2.5.1 or such longer period as shall be
                  agreed in writing by the Director and NGC, make the
                  determination referred to therein giving supporting reasons
                  and:

                  (a)      if the determination of the Director is that the
                           proposed change does not have a material adverse
                           effect upon the rights and liabilities as set out in
                           this Schedule of the TUG Parties as a group, then the
                           proposed change shall come into effect in accordance
                           with the provisions of this Agreement;

                  (b)      if the determination of the Director is that the
                           proposed change does have a material adverse effect
                           upon the rights and liabilities as set out in this
                           Schedule of the TUG Parties as a group, the Director
                           shall require that the proposed change does not come
                           into effect and in which case such proposed change
                           shall not come into effect; and

                  (c)      if the Director determines that a proposed change is
                           not to come into effect pursuant to paragraph
                           2.5.4(b), the Director shall have no authority to
                           require any modifications to the proposed change to
                           obviate or mitigate such material adverse effect or
                           to require any other change.

         2.5.5    If the Director does not make his determination within 28 days
                  of receipt of a referral or, such other period as shall have
                  been agreed in writing by the Director and NGC, in accordance
                  with the terms of paragraph 2.5.4, the proposed change shall
                  come into effect in accordance with the provisions of this
                  Agreement.

         additional party for the purposes of this Schedule only, on the terms

                  thereto and enter into similar confidentiality undertakings as
                  are given by the Obligor under this paragraph 7; and

         7.3.3    any copies of the TUG Confidential Information whether in hard

                                            subsequently selected such
                                            Representative as their choice
                                            pursuant to paragraph 6.2.2.

                  6.2.1.2           in the case of Industry Party

                                            pursuant to paragraph 6.2.2.

         6.2.2    In the event that an Industry Party did not:

                  6.2.2.1           express a preference for any elected
                                    Industry Party Representative; or

                  6.2.2.2           nominate an Industry Party Representative
                                    appointed pursuant to paragraph 7.1 of Part
                                    1 of Appendix 2 (as the case may be),

                  the elected or appointed (as the case may be) Industry Party
                  Representatives to be its Representative in accordance with
                  paragraph 7.3 or 10 (as the case may be) of Part 1 of Appendix
                  2. If it does not so select one of the elected or appointed
                  (as the case may be) Industry Party Representatives, then it

                  Industry Party who selects him under paragraphs 6.2.1 and
                  6.2.2.

         Consumer Party Representatives (one of whom must represent the
         interests of Domestic Consumers and no more than 2 may represent the
         interests of other consumers) will be appointed in accordance with Part
         2 of Appendix 2, which procedure shall be conducted by the Chairman. No
         person (including, for the avoidance of doubt, Industry Parties and
         Representatives) shall be entitled to make any claim for compensation
         or damages or any other relief whatsoever against NGC as a result of
         NGC performing its obligations in accordance with paragraph 1 of Part 2
         of Appendix 2. The Group will review and amend as necessary from time
         to time the selection procedure set out in Part 2 of Appendix 2 in
         relation to Consumer Party Representatives and will in any event carry
         out such a review not earlier than 12 months but no later than 24
         months of the Group being established.

6.4      NGC Representative

         NGC will, from time to time, appoint a person to act as the NGC

         be effected by notice in writing and delivered to the Secretary or
         tendered at a meeting of the Group.

6.5      Non-Voting Representatives

         Non-Voting Representatives are those listed in paragraph 5.1.3. Each
         Non-Voting Representative may attend meetings of the Group, and may
         speak, but cannot vote.

6.6      Appeal/Audit of election/selection procedure for Representatives

         If any Interested Party believes that the procedures set out in Parts 1
         or 2 (as the case may be) of Appendix 2 have not been followed
         correctly to a significant extent it may ask the Chairman appointed
         pursuant to paragraph 7.1 to investigate. If, following investigation
         (which shall take such form as the Chairman decides) the Chairman
         believes there are grounds for further investigation, the Chairman
         shall appoint a suitable external person or body to carry out further
         investigation. The Chairman shall carry out such investigation as
         expeditiously as is reasonably practicable. In any event, the Chairman
         shall report on the progress of such investigation at the next meeting
         of the Group following a request by any Interested Party to investigate
         and subsequent meetings of the Group if necessary.

6.7      Findings of Appeal/Audit of Election/Selection Procedure for
         Representatives

         If, as a result of an investigation carried out under paragraph 6.6
         above it is found:

         6.7.1    that the number of votes allocated to Industry Parties is
                  incorrect; or

         6.7.2    that as a result of an incorrect allocation of votes between
                  Industry Parties or a miscalculation of votes, an Industry
                  Party Representative would have not been elected had the votes
                  been allocated or calculated correctly; or

         6.7.3    that the procedure for the selection of Consumer Party
                  Representatives had not been followed correctly to a
                  significant extent,

         then the Representatives elected or selected (as the case may be) shall
         remain Representatives of the Group until the next election or
         selection procedure (as the case may be). In the event of the votes
         allocated between Industry Parties being incorrect then NGC shall
         re-allocate the votes appropriately between Industry Parties.

7.       CHAIRMAN

7.1      Upon the retirement or removal by NGC of the first and each successive
         Chairman, NGC shall appoint a person to act as Chairman. The Chairman
         shall be an executive director of NGC except for the first Chairman who
         shall be the "Director, Commercial and System Strategy" as at 1 April
         1997.

7.2      The Chairman shall preside at every meeting of the Group at which he is
         present. If the Chairman is unable to be present at a meeting, the
         Vice-Chairman appointed pursuant to paragraph 7.3 shall act as
         Chairman. If neither the Chairman nor the Vice-Chairman is present
         within half an hour after the time appointed for holding the meeting,
         the Representative present may appoint a Representative to be Chairman
         of the meeting provided that such meeting is quorate in accordance with
         paragraph 13.2.

7.3      At the first meeting of the Group (and from time to time thereafter)
         the Representatives present at such meeting shall elect, by a simple
         majority on a show of hands, one of the Representatives to be
         Vice-Chairman. Representatives present shall each have one vote. For
         the avoidance of doubt Industry Party Representatives will not be
         required to vote in accordance with the wishes of those Interested
         Parties whom he represents and NonVoting Representatives and the NGC
         Representative present shall each have one vote on the election of a
         Vice-Chairman.

7.4      The Chairman shall have and carry out only such duties and
         responsibilities and exercise such powers as are expressly provided in
         this Constitution. The Chairman shall exercise impartially all such
         duties, responsibilities and powers.

7.5      If the Chairman does not carry out his duties and responsibilities in
         accordance with paragraph 7.4, the Group may pass a resolution which
         shall be recorded in the minutes of the Group expressing its concern at
         that failure.


8.       SECRETARY

8.1      NGC shall, unless the Group decides otherwise, perform the secretarial
         role in reaction to the Group and shall provide a Secretary together
         with such other staff as it shall deem necessary. NGC shall notify each
         Representative of the identity and address for correspondence of the
         Secretary as soon as reasonably practicable after his appointment.

8.2      The Secretary shall not be a Representative of the Group and shall not
         be entitled to cast a vote at any meeting although he shall have the
         right to speak at a meeting.

8.3      The Secretary's duties shall be to attend to the day to day operation
         of the Group and in particular to.

                  requisite notices;

         8.3.2    maintain a register of names and addresses of Representatives
                  and the Chairman and alternates as appointed from time to
                  time; and

         8.3.3    keep minutes of all meetings.


9.       ALTERNATES

9.1      Each Representative shall have the power to appoint any individual to
         be his alternate and may at the Representative's discretion remove an
         alternate so appointed.

9.2      Any appointment or removal of an alternate shall (unless the Chairman
         otherwise agrees) be effected by notice in writing executed by the
         Representative appointing the alternate and delivered to the Secretary
         or tendered at a meeting of the Group.

9.3      If the Representative appointing the alternate so requests, an
         alternate shall be entitled to receive notice of all meetings of the
         Group or of meetings of sub-committees or working groups of which the
         Representative who appointed him is a member, and for the purpose of
         the proceedings at the meeting, the provisions of this Constitution
         shall apply as if the alternate were a Representative. Every person
         acting as an alternate shall have the votes of each Representative for
         whom that person acts as alternate, in addition to that person's own
         votes if he is also a Representative.

9.4      An alternate Representative shall cease to be an alternate if the
         Representative who appointed him ceases for any reason to be a
         Representative.

9.5      References in this Constitution to a Representative shall, unless the
         context otherwise requires, include his duly appointed alternate.


10.      VACATION OF OFFICE

10.1     The office of a Representative shall be vacated if:

         10.1.1   the Representative resigns his office by notice delivered to
                  the Secretary; or

         10.1.2   three consecutive meetings of the Group have been held at
                  which neither that Representative nor his alternate has been
                  present, neither having submitted to the Chairman an
                  explanation for absence which is acceptable in the reasonable
                  opinion of the Chairman appointed pursuant to paragraph 7.1;
                  or

         10.1.3   the Representative conducts himself in a manner which in the
                  reasonable opinion of the Chairman appointed pursuant to
                  paragraph 7.1 is unbecoming to the office of a Representative.

10.2     In the event that the office of an Industry Party Representative is
         vacated pursuant to paragraph 10.1 or such Industry Party
         Representative dies or ceases to be employed or exclusively retained by
         the company or other entity (whether or not a corporate body) which
         employed him at the time he was elected or (as the case may be)
         nominated then:

         10.2.1   those Industry Parties whom such Industry Party Representative
                  represents (as identified on the list published by NGC
                  pursuant to paragraph 11 of Part 1 of Appendix 2) may select a
                  new Industry Party Representative;

         10.2.2   in the event that an Industry Party does not wish the newly
                  selected Industry Party Representative to be its
                  Representative it may select one of the other elected Industry
                  Party Representatives to be its Representative;

         10.2.3   if it does not wish the newly elected Industry Party
                  Representative to be its Representative and it does not so
                  select one of the other elected Industry Party
                  Representatives, then it shall cease to be represented.

         In any event such Industry Party shall notify the Secretary of its
         selection or non- selection as the case may be.

10.3     In the event that the office of a Consumer Party Representative is
         vacated pursuant to paragraph 10.1 or such Consumer Party
         Representative dies, the Electricity Consumers' Committees Chairmen's
         Group shall be invited to select a new Consumer Party Representative.

10.4     In the event that the office of a Non-Voting Representative or the NGC
         Representative is vacated pursuant to paragraph 10.1 or such
         Representative dies then the Executive Committee (PEC) or the Director
         or the Grid Code Review Panel or NGC (as the case may be) will appoint
         a new Representative.

10.5     Any Representative elected or appointed pursuant to paragraphs 10.2 or

                  the case may be) of Representatives in accordance with the
                  procedures set out in paragraphs 6.1 and 6.3.


12.      NOTICE OF MEETINGS

12.1     All meetings shall be called by the Secretary on at least 14 days

         day for which it is given), or by shorter notice if so agreed by all
         Representatives and the Chairman.

12.2     If at any time a person has not been appointed as Secretary, or the
         Secretary is for any reason unable to act, the Chairman shall make
         alternative arrangements to convene meetings.

12.3     The notice of each meeting shall be given to all Representatives and to
         the Chairman and shall contain the time, date and venue of the meeting,

         matters to be considered at the meeting and provided such notice is
         given at least 10 days (exclusive of the day on which it is served and

12.6     Each Representative and the Chairman shall from time to time

13.2     8 Voting Representatives and the NGC Representative present in person
         or by their alternates shall constitute a quorum for a meeting of the
         Group.

13.3     Subject to the provisions of paragraph 13.5, the Chairman may, after a
         reasonable period of time from the time appointed for holding any
         meeting of the Group decide that because a quorum is not present, the
         meeting shall be adjourned. The meeting shall be adjourned to such day,
         time and place as the Secretary may notify to Representatives and to
         the Chairman within 3 days of the adjournment. Alternatively, the
         Chairman may with the consent of all Representatives present decide
         that the meeting of the Group should proceed. In the case of a meeting
         which, at any time, ceases to be quorate the Chairman any also with the
         consent of all Representatives remaining decide that such meeting
         should continue.

13.4     A meeting adjourned in accordance with paragraph 13.3 shall not be
         called to take place within one week of the adjournment but may be
         called on less than 14 days notice. If at such adjourned meeting a
         quorum is not present within a reasonable period of time (as the
         Chairman may decide) from the time appointed for holding the meeting,
         the meeting shall not take place.

13.5     Only matters identified in the agenda referred to in paragraph 12.3 (or
         a revised agenda submitted pursuant to paragraph 12.5), and which have
         been discussed as an agenda item at a meeting of the Group which met
         the requirements of paragraph 13.2 at least 4 weeks prior, shall be
         resolved upon at a meeting (but this shall not prevent matters raised
         under the heading "Any Other Business" being discussed), provided that
         the meeting at which a matter is to be resolved upon is itself quorate
         or (in the case of a meeting which is not quorate throughout) the
         matter is resolved upon in that part of the meeting which was quorate.

13.6     In the event that:

         13.6.1   there was some defect in the appointment of either a

         of Appendix 2.


3.       RESOLUTION OF DISPUTES

         NGC and any Industry Party who raises an objection or query under
         paragraph 2 of this Part 1 of Appendix 2, shall attempt to resolve such

4.       DISPATCH OF NOMINATION FORMS

         No later than 21st January each year, NGC will send to each Industry
         Party a Nomination Form on which to nominate one person who must have
         agreed to stand as an Industry Party Representative if elected (and who

         place, or indicate in some other manner agreed with the Chairman
         appointed pursuant to paragraph 7.1), but who need not be an employee
         of an Industry Party.


5.       PRINCIPLES OF NOMINATIONS

5.1      Each Industry Party:

         5.1.1    may only nominate one person to stand for election as an
                  Industry Party Representative, and

         5.1.2    shall ensure that there will only be one person who is
                  connected (employee, consultant or otherwise) with such
                  Industry Party and who has agreed to stand for election as an
                  Industry Party Representative.

5.2      Each Industry Party that is a member of an Industry Party Group shall
         be obliged to:

         5.2.1    nominate the same person as the other Industry Party or
                  Industry Parties (as the case may be) who are also members of
                  such Industry Party Group; and

         5.2.2    ensure that there will only be one person who is connected
                  (employee, consultant or otherwise) with such Industry Party
                  Group and who has agreed to stand for election as an Industry
                  Party Representative.


6.       RETURN OF NOMINATION FORMS

         No later than 5th February each year, each Industry Party shall return
         to NGC the Nomination Form. In the event that NGC does not receive a
         duly completed Nomination Form within that time it shall be presumed
         that any Industry Party which has not returned a duly completed
         Nomination Form does not wish to nominate a person to stand as an
         Industry Party Representative.


7.       RECEIPT OF 15 OR FEWER NOMINATIONS

7.1      In the event that 15 or fewer than 15 nominations are received, there
         will be no election and each of the nominees shall be appointed as an
         Industry Party Representative.

7.2      No later than 24th February each year NGC shall send to all Industry
         Parties who did not nominate one of the Industry Party Representative
         so appointed, a list of the Industry Party Representatives so
         appointed.

7.3      No later than 4 March each year, such Industry Parties will notify NGC
         whether it wishes to select a Representative pursuant to paragraph
         6.2.2 and if so the name of the Representative.

8.       RECEIPT OF NOMINATION IN EXCESS OF 15

8.1      DESPATCH OF VOTING PAPERS

         In the event that more than 15 nominations are received, NGC shall draw
         up a complete list of nominations on a Voting Paper which shall then be
         sent to all Industry Parties by 24th February each year.


8.2      MARKING OF VOTING PAPERS

         On receipt, each Industry Party shall mark the Voting Paper to rank the
         nominees in order of preference until they are indifferent about the
         remaining candidates. Each Industry Party that is a member of an
         Industry Party Group shall when marking the Voting Paper to rank the
         nominees in order of preference be obliged to rank the same nominees in
         the same order of preference as the other Industry Party of Industry
         Parties (as the case may be) who are also members of such Industry
         Party Group.


8.3      RETURN OF VOTING PAPERS

         No later than 10th March each year, each Industry Party shall return to
         NGC its Voting Paper. In the event that NGC does not receive a duly
         completed Voting Paper within that time it shall be presumed that any
         Industry Party which has not returned a duly completed Voting Paper
         does not wish to express a preference about any of the candidates on
         the Voting Paper.


8.4      COUNTING OF VOTES

         The votes for first preferences will be totalled by NGC to rank the
         nominees in order of popularity.


8.5      ELIMINATION OF NOMINEES

         The nominee with the fewest votes shall be eliminated and shall take no
         further part in the election process. NGC shall transfer the votes of
         all those Industry Parties who voted for that nominee to the nominee
         who is the next highest preference (and who has not already been
         eliminated) of such Industry Party or Industry Parties (as the case may
         be).

8.6      RE-RANKING OF NOMINEES

         NGC will then re-rank the nominees and this process will be repeated
         until there are only 15 nominees left who will become the 15 Industry
         Party Representatives.

8.7      EQUAL VOTES

         In the event that there are two or more nominees with equally the
         fewest votes then each such nominee will be eliminated except in the
         event when such elimination would result in there being fewer than 15
         nominees left. In such circumstance the lowest nominees will be ranked
         according to the number of first preference votes to determine which
         shall fill the remaining seat(s) on the Group. If the lowest ranked
         nominees are also equal on the number of first preference votes then
         NGC shall rank according to second preference votes and so on until one
         nominee ranks higher than the other. In the event that there is still
         no outcome the nominees concerned will draw lots.


9.       VOTING BY AN INDUSTRY PARTY GROUP

9.1      NGC shall not be under any obligation to monitor or to ensure that
         nominations made by or the voting by (as the case may be) Industry
         Parties that are members of the same Industry Group as part of the
         election procedure for Industry Party Representatives is in accordance
         with the provision of:

         9.1.1    paragraph 5.4, and

         9.2.1    paragraph 5.2 and 8.2 of this Part 1 or Appendix 2.

         provisions relating to Industry Party Groups set out in:

         9.2.1    paragraph 5.4; and

         9.2.2    paragraphs 5.2 and 8.2 of this Part 1 of Appendix 2.


10.      SELECTION OF INDUSTRY PARTY REPRESENTATIVES

         No later than 20th March each year NGC shall send to each Industry
         Party who did not express a preference for any elected Industry Party
         Representative a list of the Industry Party Representatives elected. No
         later than 31st March each year each such Industry Party shall notify
         NGC whether it wishes to select a Representative pursuant to paragraph
         6.2.2 and if so, the name of the Representative.

11.      NOTIFICATION OF INDUSTRY PARTY REPRESENTATIVES

         On completion of the election procedure set out in this Part 1 of
         Appendix 2 (including selection by those who did not express a
         preference as provided in paragraph 10 of this Part 1 of Appendix 2),
         NGC shall publish to Industry Parties:

         (a)      a list of elected Representatives and the Industry Parties
                  whom they each represent.

         (b)      a list of all Industry Parties and the number of votes
                  allocated to each Industry Party pursuant to Appendix 3
                  provided that NGC shall not disclose the number of votes
                  allocated to Industry Parties who have notified the Chairman
                  in writing that they elect not to have the number of votes
                  allocated to them disclosed. Industry Parties may only elect
                  not to have the number of votes allocated to them disclosed if
                  they have fewer than 500,000 votes.

         A maximum of 150,000,000 votes shall be allocated between Industry
         Parties and Consumers Party Representatives. Industry Parties shall,

                  all data used by NGC in calculating the number of votes to be
                  allocated to Industry Parties in respect of each TUG Year will
                  be based on the 12 month period expiring on 30th November

                  (as those expressions are respectively defined in the Pooling
                  and Settlement Agreement) to NGC broken down on a company by
                  company basis provided always that if the Settlement System
                  Administrator fails to supply such data the Industry Parties
                  will provide such data direct to NGC.

         2.3      DATA

                  the data to be utilized is as follows:

                  (B)      in relation to payments made and/or from NGC, the

                                       (or equivalents agreements) with each
                                       Industry Party, provided that

                                       (a)       for the purpose of arriving at
                                                 such amount, any generation or
                                                 demand infrastructure charges
                                                 payable to an Industry Party in

                                                 Site shall be deemed to be a
                                                 payment to NGC; and

                                       (b)       connection charges invoiced
                                                 internally by NGC on NGC
                                                 Interconnections Business shall
                                                 not (for the avoidance of
                                                 doubt) be included, and

                                       (c)       any capital contribution
                                                 (whether in monetary form or
                                                 otherwise) made other than
                                                 annually shall be converted
                                                 into a deemed annual charge on
                                                 the basis of the applicable
                                                 depreciation period;

                           (ii)        the sum of the magnitude of amounts
                                       invoiced under Ancillary Service

                           (iii)       equivalent amounts invoiced under an
                                       Interconnection Agreement.

         2.4      VOTES ALLOCATION

                  votes will be allocated to Industry Party on the basis of 50%
                  on energy traded within the England and Wales electricity pool
                  (calculated in accordance with paragraph 2.3 of this Appendix
                  3) and 50% on payments to/from NGC (calculated in accordance
                  with paragraph 2.3 of this Appendix 3) as follows:

                  Industry Party's Energy Traded (MWhrs)
                  --------------------------------------
                           Total Energy Traded (MWhrs)          x 67,500,000

                  plus

                  Total Payments of Industry Party
                  --------------------------------
                           Total Payments                       x 67,500,000;

         2.5      Rounding Down of Votes

                  votes allocated to each Industry Party shall be rounded down
                  to the nearest whole number.

         2.6      Reallocation of Votes

                  the number of votes allocated to each Industry Party will not
                  be changed between elections other than as provided in
                  paragraph 6.7. If an Industry Party starts trading energy or
                  money starts to flow between NGC and such Industry Party
                  between elections of Industry Party Representatives, such
                  Industry Party will not be allocated any votes until the next
                  election. For the avoidance of doubt, Industry Parties ceasing
                  to trade between election will not have their votes
                  reallocated until the next election of Industry Party
                  Representatives. An Industry Party either acquiring or
                  divesting itself of assets will not result in a reallocation
                  of votes until the next election.

3.       CONSUMER PARTY REPRESENTATIVES

         3.1      VOTING ALLOCATION

                  each Consumer Party Representative will be allocated 5,000,000
                  votes;

         3.2      FEWER THAN 3 CONSUMER PARTY REPRESENTATIVES

                  in the event that fewer than three Consumer Party
                  Representatives are nominated or fewer than three are
                  appointed pursuant to Part 2 of Appendix 2 then the 5,000,000
                  votes which would have been allocated to such Consumer Party
                  Representative will not be transferred to the Consumer Party
                  Representative or Representatives (as the case may be) who
                  have been selected. For the avoidance of doubt, if a Consumer
                  Party Representative decides not to exercise its voting power
                  such votes will not be transferred to any other Consumer Party
                  Representative selected.

  FORM OF CONSUMER PARTY REPRESENTATIVES' CONFIDENTIALITY LETTER OF UNDERTAKING


To The National Grid Company plc ("NGC")
and the Industry Parties (as hereinafter      [name of Consumer Representative]
defined) as at the date hereof and as                  [address]
from time to time hereafter                            [date]


Dear Sirs

TRANSMISSION USERS GROUP

1.       I refer to the Constitution and Rules of the Transmission Users Group
         as amended from time to time (the "Constitution"). Words of expressions
         used in this letter shall have the same meaning as defined in the
         Constitution.

2.       I hereby undertake to the Industry Parties as at the date hereof and
         from time to time hereafter as follows:

         2.1      to comply with the provisions of the Constitution; and

         2.2.     to preserve the confidentiality of, and not directly or
                  indirectly reveal, report, publish, disclose, transfer or use
                  for my own purpose, TUG Confidential Information (as defined
                  in paragraph 5 of this letter) except with the prior consent
                  in writing of NGC and the Industry Parties or in the
                  circumstances set out in paragraph 3 of this letter.

3. The circumstances referred to in paragraph 2 of this letter are:

         3.1      where the TUG Confidential Information is in the public domain
                  before it is furnished to me; or

         3.2      where the TUG Confidential Information after it is furnished
                  to me:

                  (a)      is acquired me in circumstances to which this letter
                           does not apply;

                  (b)      is acquired by me in circumstances to which this
                           letter does not apply but then ceases to be subject
                           to the restrictions imposed by this letter; or

                  (c)      enters the pubic domain.

                  and in any case otherwise than as a result of (a) a breach by
                  me of my obligations in this letter or (b) a breach by the
                  person who disclosed that TUG Confidential Information of that
                  person's confidentiality obligation and I am aware of such
                  breach; or

         3.3      if I am required or permitted to make disclosure of the TUG
                  Confidential Information to any person:

                  (a)      in compliance with the requirements of a Competent
                           Authority; or

                  (b)      in compliance with any other requirement or law; or

                  (c)      in response to a requirement of any stock exchange or
                           regulatory authority or the Panel on Take-overs and
                           Mergers; or

                  (d)      pursuant to any judicial or arbitral process or
                           tribunal having jurisdiction in relation to me; or

         3.4      if I make disclosure of the TUG Confidential Information to my
                  consultants and professional advisers in each case on the
                  basis set out in paragraph 4; or

         3.5      if I make disclosure of the TUG Confidential Information in
                  circumstances where I am expressly permitted or required to
                  disclose that information under the terms of any agreement or
                  arrangement with the party to whose affairs such TUG
                  Confidential Information relates.

4.       I hereby agree that I will adopt procedures ensuring the
         confidentiality of TUG Confidential Information which I am obliged to
         preserve as confidential under paragraph 2.2 of this letter. These
         procedures shall include, but shall not necessarily be limited to:

         4.1      Consumer Parties, my consultants and professional advisers in
                  receipt of TUG Confidential Information will be made fully
                  aware of my obligations of confidence in relation to the TUG
                  Confidential Information and will enter into similar
                  confidentiality undertakings as are given by me in this
                  letter; and

         4.2      any copies of the TUG Confidential Information whether in hard
                  copy or computerized form will clearly identify the TUG
                  Confidential Information as confidential.

5.       In this letter TUG Confidential Information means all data and other
         information supplied to me by another Representative or Industry Party
         in connection with the Constitution.

6.       The obligations relating in confidentiality contained in paragraphs 2
         to 6 inclusive of this letter shall continue to be binding on me after
         I have ceased to be a Representative for whatever reason.

7.       The terms of Clause 15 (limitation of liability) of the Master
         Agreement shall apply to this letter as if set out in full herein.

8.       This letter shall be governed by and construed in accordance with
         English law.

               made between NGC and the Users as amended by an Agreement to

                    be passed to the Transmission Users Group but further
                    agree that, unless and until otherwise agreed by the
                    Parties in writing, and notwithstanding and without
                    prejudice to Clause 25.1 of this Agreement, this
                    Schedule and the Appendices (except this paragraph 2)
                    may be varied upon the terms and conditions of sub-
                    paragraphs 2.2 to 2.5 inclusive.

               (b)  Solely for the purposes of enabling this Schedule and

                    upon the terms and conditions of sub-paragraphs 2.2 to
                    2.5 inclusive as specified in sub-paragraph 2.1(a), the
                    contents of this Schedule and the Appendices as varied
                    from time to time shall be deemed to be incorporated as
                    a separate Appendix into each and every Supplemental
                    Agreement entered into by a User and in force from time
                    to time, and the Parties hereby agree that,
                    notwithstanding any contrary provision, express or
                    implied in this Agreement or any Supplemental
                    Agreement, each such Appendix to a Supplemental
                    Agreement shall only be capable of variation with the
                    agreement in writing of all Parties or by way of a
                    variation to this Schedule and the Appendices upon the
                    terms and conditions of sub-paragraphs 2.2 to 2.5
                    inclusive and not otherwise (and Sub-Clause 1.2 of this
                    Agreement shall be read and construed accordingly).
                    Such Appendix is hereafter referred to in this

                         Supporting Documentation may not be so submitted
                         for the purposes of this paragraph 2 if the effect
                         of the Proposed Variation would in any way
                         conflict with, or otherwise be inconsistent with,
                         the charging principles (as amended from time to
                         time) set out in Appendix 8 (save to the extent
                         the Proposed Variation comprises solely a
                         variation to such charging principles or includes
                         a variation to such charging principles remedying
                         the conflict or inconsistency); and

                    (ii) for the purposes of this paragraph 2, written
                         details of a Proposed Variation shall only be
                         deemed to have been submitted as a TUG Issue at a
                         meeting of the Transmission Users Group if such
                         details include a statement to the effect that
                         they are being submitted pursuant to and for the
                         purposes of this paragraph 2.

               (b)  If this Schedule and/or the Appendices shall not have
                    been amended in accordance with Clause 25.1 of this
                    Agreement to effect such Proposed Variation, then at
                    any time after expiry of a period of 120 days, but not
                    later than 180 days, following the date on which
                    written details of the Proposed Variation and
                    Supporting Documentation were submitted at a meeting of
                    the Transmission Users Group in accordance with sub-
                    paragraph 2.2(a), the Proposing Party shall be
                    entitled:

                    (i)  where the Proposing Party is a User, to serve
                         written notice on NGC requiring NGC to serve
                         written notice on all other Users of the Proposing
                         Party's intention to require NGC pursuant to sub-
                         paragraph 2.2(c)(i) to refer the Proposed
                         Variation to the Director for determination; or

                    (ii) where the Proposing Party is NGC, to serve written
                         notice on all Users of its intention to refer the
                         Proposed Variation to the Director in accordance
                         with sub-paragraph 2.2(c)(ii),

                    each such notice to be copied to the Director.  NGC
                    shall so notify all other Users as referred to in sub-
                    paragraph 2.2(b)(i) within 10 days following receipt of
                    the notice from the Proposing Party.

               (c)  If no such amendments to this Schedule and/or the
                    Appendices to effect such Proposed Variation shall have
                    been made within 30 days following receipt (or issue,
                    as the case may be) by NGC of the notice referred to in
                    sub-paragraph 2.2(b), then the Proposing Party shall be
                    entitled:

                    (i)  where the Proposing Party is a User, within a
                         further 30 day period, to serve written notice on
                         NGC requiring NGC to refer the Proposed Variation
                         to the Director, whereupon NGC shall be obliged
                         within 10 days following receipt thereof by
                         written notice (copied to all other Users) to
                         refer the Proposed Variation to the Director for
                         determination; or

                    (ii) where the Proposing Party is NGC, within a further
                         30 day period, by written notice (copied to all
                         Users) to refer the Proposed Variation to the
                         Director for determination.

          2.3  Each reference by NGC of a Proposed Variation to the
               Director referred to in sub-paragraph 2.2(c) shall be made
               in the manner of a variation to each Supplemental Appendix
               proposed by NGC pursuant to Condition 10C(3) of the
               Transmission License, and shall be accompanied by a request
               from NGC to the Director to settle any dispute relating
               thereto.  When making each such reference, NGC shall provide
               the Director with copies of the written details and
               Supporting Documentation in relation to the Proposed
               Variation first submitted by the Proposing Party at a
               meeting of the Transmission Users Group as referred to at
               sub-paragraph 2.2(a) and, where the Proposing Party is a
               User, NGC shall invite the Director to raise any questions
               or queries concerning the Proposed Variation direct with the
               User concerned.

          2.4  If a reference shall have been made by NGC to the Director
               pursuant to sub-paragraph 2.2(c) and the Director shall have
               made a determination in accordance with Condition 10C(3) of
               the Transmission License requiring each Supplemental
               Appendix and/or the provisions of this Schedule and/or the
               Appendices to be varied, then the Parties shall give effect
               to any such variation so determined to be made by varying
               each of their respective Supplemental Appendices and/or the
               provisions of this Schedule and/or the Appendices
               accordingly, and each Party hereby authorises and instructs
               NGC to make all such variations on its behalf and undertakes
               not to withdraw, qualify or revoke such authority and
               instruction at any time.  In the absence of any such
               determination by the Director, no such variations shall be
               made.

          2.5  The Parties acknowledge and agree that the Transmission
               Users Group shall be requested to review each of the matters
               described in Appendix 7 by the respective date (if any)
               shown opposite each therein.  In carrying out such review,
               the Transmission Users Group shall be requested to take into
               account the respective applicable principles (if any) set
               out therein and to give due and proper consideration to any
               matter referred to it by the Director.  For the avoidance of
               doubt, following each such review NGC or any User may raise
               a Proposed Variation with respect thereto in accordance with
               sub-paragraph 2.2(a).  It is further agreed that:

               (a)  NGC shall consider and, no later than 31st December,
               1999, report to the Transmission Users Group on the
               practicalities of establishing a unified mechanism for the
               provision of voltage support for the NGC Transmission
               System; and

               (b)  the Transmission Users Group shall be requested, no
               later than 31st March, 2000, to invite the Grid Code Review
               Panel to review the provisions of the Grid Code with respect
               to Reactive Power in light of this Schedule.

          2.6  For the avoidance of doubt:

               (a)  the provisions of sub-paragraphs 2.2 to 2.5 inclusive
                    shall constitute the entirety of the rights of Parties
                    (whether under this Agreement or otherwise) to refer
                    (or to require NGC to refer) to the Director for
                    determination any variation to this Schedule 5 and/or
                    the Appendices, and each of the Parties hereby agrees
                    that, save in the circumstances provided in sub-
                    paragraph 2.3, no request shall be made to the Director
                    under Condition 10C(3) of the Transmission License to
                    settle any dispute relating to any Proposed Variation
                    where NGC is the Proposing Party; and

               (b)  nothing in this paragraph 2 shall confer on any Party
                    any right to refer (or to require NGC to refer) to the
                    Director for determination any variation or proposed
                    variation to any part or parts of this Agreement other
                    than this Schedule 5 and the Appendices; and

               (c)  the provisions of this paragraph 2 may only be varied

                    Agreement.

          3    DISPUTE RESOLUTION
               ------------------

          3.1  Save in relation to any dispute or difference concerning a
               Proposed Variation (in respect of which paragraph 2 shall
               apply), and subject always to subparagraph 3.2, any dispute
               or difference of whatever nature howsoever arising under out
               of or in connection with this Schedule and/or the Appendices
               (in this paragraph 3 referred to as a "Dispute") shall be
               and hereby is referred to arbitration pursuant to the
               arbitration rules of the Electricity Arbitration Association
               in force from time to time.

          3.2  (a)  In this sub-paragraph 3.2, each Party which is party to
                    the Dispute in question is referred to as "a Disputing
                    Party" and "Disputing Parties" shall be construed
                    accordingly.

               (b)  Before submitting any notice under the arbitration
                    rules commencing arbitration proceedings in relation to
                    any Dispute, unless a notice shall have been served in
                    respect of that Dispute pursuant to sub-paragraph
                    3.2(c), a Disputing Party shall first serve written
                    notice on all other Disputing Parties of its intention
                    to commence arbitration proceedings.  Arbitration
                    proceedings may not then be commenced until the 30 day
                    period referred to in sub-paragraph 3.2(c)(ii) shall
                    have elapsed without a notice pursuant to that sub-
                    paragraph having been served or, where such notice has
                    been served within such period, except in the
                    circumstances provided in sub-paragraphs 3.2(d) and
                    (e).

               (c)  If a Disputing Party reasonably believes that the
                    subject matter of the Dispute is directly relevant to,
                    or the resolution of the Dispute would have a material
                    effect upon, any one or more other Parties not being
                    Disputing Parties, then that Disputing Party may:

                    (i)  for so long as no notice is served in accordance
                         with sub-paragraph 3.2(b) above, at any time, or

                    (ii) upon receipt of any such notice, within 30 days
                         thereafter,

                    serve written notice on all other Disputing Parties of
                    its intention to raise the Dispute as a TUG Issue at a
                    meeting of the Transmission Users Group.  Upon receipt
                    of such notice, no Disputing Party may subsequently
                    commence arbitration proceedings except in the
                    circumstances provided in sub-paragraphs 3.2(d) and
                    (e).

               (d)  Not earlier than 30 days nor later than 90 days after a
                    notice is served pursuant to sub-paragraph 3.2(c)
                    above, the Representative of that and/or any other
                    Disputing Party may submit written details of the
                    Dispute as a TUG Issue at a meeting of the Transmission
                    Users Group.  Provided it shall first have been given
                    the opportunity to consult with regard to the nature
                    and scope of confidential information relating to its
                    affairs proposed to be disclosed, each Disputing Party
                    hereby consents to such disclosure of confidential
                    information (but not rates and prices) relating to its
                    affairs to the extent relevant to the Dispute.  If such
                    written details are not so submitted prior to expiry of
                    such 90 day period, then any Disputing Party wishing to
                    commence arbitration proceedings in relation to the
                    Dispute in question may thereafter do so.

               (e)  Upon the expiry of the period of 120 days after the
                    date on which written details of the Dispute are
                    submitted at a meeting of the Transmission Users Group
                    in accordance with subparagraph 3.2(d), any Disputing
                    Party wishing to commence arbitration proceedings in
                    relation to the Dispute in question may thereafter do
                    so.

          3.3  Clause 26.1 of this Agreement shall be read and construed
               accordingly.


          4.   OBLIGATORY REACTIVE POWER SERVICE - DEFAULT PAYMENT
               ---------------------------------------------------
               ARRANGEMENTS
               ------------

          4.1  Notwithstanding any other provision of this Agreement, the
               provisions of this Schedule and the Appendices, together
               with the Ancillary Services Agreements referred to in sub-
               paragraph 4.6, shall govern the rights and obligations of
               the Parties with respect to payments to be made by NGC to
               Users for the provision of the Obligatory Reactive Power
               Service.

          4.2  Subject always to paragraph 5, and notwithstanding:

               (a)  the provisions of the Works Programme for reactive
                    power ancillary services agreed by Pool Members on 1st
                    March, 1994, as adopted from 1st August, 1994; and

               (b)  the provisions of any Ancillary Services Agreement now
                    or hereafter in effect (but subject always to
                    subparagraph 6.2),

               the payments to be made by NGC to Users for the provision of
               the Obligatory Reactive Power Service in all Ancillary
               Services Agreements under which Users are or will be paid
               for the Obligatory Reactive Power Service shall, subject
               always to sub-paragraphs 2.5 and 4.7, in respect of all
               periods from (and including) 1st October, 1997 to (and
               including) 31st March, 2000 comprise solely payments for
               capability and utilisation, and thereafter comprise solely
               payments for utilisation, in each case determined in respect
               of each Settlement Period in accordance with sub-paragraph
               4.3.

          4.3  Save to the extent and for the duration of any Market
               Agreement (as defined in sub-paragraph 5.1) which may be
               entered into between NGC and a User as referred to in
               paragraph 5:

               (a)  the utilisation and capability payment for provision of
                    the Obligatory Reactive Power Service from Despatch
                    Units shall be determined in accordance with the
                    provisions of Appendix 1; and

               (b)  the utilisation and capability payments for provision
                    of the Obligatory Reactive Power Service from Non-
                    Centrally Despatched Generating Units shall be
                    determined on a basis to be agreed between NGC and each
                    relevant User but, so far as reasonably practicable,
                    consistent with the provisions of Appendix 1 (but so
                    that such payments shall not become due and payable
                    from NGC to any such User with effect from a date
                    earlier than that on which the relevant Ancillary
                    Services Agreement referred to in subparagraph 4.6 is
                    so amended or concluded).

          4.4  The Parties acknowledge and agree that, as at the date this
               Schedule comes into effect:

               (a)  the totality of payments for the provision of the
                    Obligatory Reactive Power Service, determined in
                    accordance with the provisions of this paragraph 4,
                    reflect so far as reasonably practicable the overall
                    variable costs (on the basis of the charging principles
                    set out in Appendix 8) incurred across all relevant
                    Generating Units of the provision of the Obligatory
                    Reactive Power Service (whether or not payments are
                    made in respect of those Generating Units pursuant to
                    this paragraph 4 or pursuant to Market Agreements
                    entered into in accordance with paragraph 5); and

               (b)  without prejudice to the review of the indexation
                    factor specified as item 4 in Appendix 7, such totality
                    of payments will continue to reflect those overall
                    variable costs notwithstanding all and any variations
                    thereto reasonably anticipated at such date.

          4.5  It is hereby agreed and acknowledged that nothing in this
               Schedule and the Appendices shall affect in any way the
               obligation on each User to comply with the provisions of the
               Grid Code insofar as they relate to Reactive Power.  For the
               avoidance of doubt, and without limiting the foregoing, it
               is hereby agreed and acknowledged that, notwithstanding that
               the payments for the Obligatory Reactive Power Service with
               effect from 1st April, 2000 shall, subject always to sub-
               paragraph 2.5, comprise solely payments for utilisation,
               nothing in this Schedule and the Appendices shall relieve
               Users from the obligation to comply with the provisions of
               the Grid Code in relation to Reactive Power by virtue of
               Sub-Clause 9.3 of this Agreement or otherwise howsoever.

          4.6  Ancillary Services Agreements have been and will continue to
               be entered into bilaterally between NGC and Users but it is
               intended that subject as provided below, Ancillary Services
               Agreements between NGC and Users providing the Obligatory
               Reactive Power Service will be amended or (if not in
               existence when this Schedule takes effect) concluded so as
               to give effect to the provisions of sub-paragraphs 4.2 and
               4.3.  Subject always to sub-paragraphs 4.8 and 6.2, NGC and
               each relevant User therefore agree, as soon as reasonably
               practicable, to amend the existing Ancillary Services
               Agreement or conclude a new Ancillary Services Agreement in
               respect of each relevant Generating Unit in order to give
               effect to the provisions of sub-paragraphs 4.2 and 4.3.

          4.7  For the avoidance of doubt, no payments referred to in this
               paragraph 4 shall be payable by NGC to a User in relation to
               any Generating Unit unless and until the relevant Ancillary
               Services Agreement is so amended or concluded as provided in
               sub-paragraph 4.6.

          4.8  Notwithstanding the foregoing provisions of this paragraph
               4, and without prejudice to paragraph 7, NGC shall only be
               obliged to amend or conclude any Ancillary Services
               Agreement with regard to any Generating Unit if:

               (a)  the leading or lagging Reactive Power capability
                    required of that Generating Unit in accordance with
                    Grid Code CC 6.3.2 is 15 Mvar or more (measured at the
                    Commercial Boundary); and

               (b)  where that Generating Unit is not subject to Central
                    Despatch, NGC and the relevant User shall have agreed
                    terms (to be incorporated into the Ancillary Services
                    Agreement) with regard to despatch facilities,
                    including the ability for NCC to obtain relevant
                    technical, planning and other data in connection
                    therewith; and

               (c)  there exists in rotation to that Generating Unit
                    metering facilities meeting the requirements of
                    Appendix 4.

               -------------------------------------------------------
               POWER SERVICES - MARKET PAYMENT MECHANISM
               -----------------------------------------

          5.1  Nothing in this Schedule and the Appendices, and nothing in
               any Ancillary Services Agreement entered into or amended in
               accordance with sub-paragraph 4.6, shall prevent or
               restrict:

               (a)  the entering into or amendment of any Ancillary
                    Services Agreement between NGC and any User to provide
                    for the making of payments by NGC to that User for the
                    provision of the Obligatory Reactive Power Service on
                    an alternative basis to that set out or referred to in
                    paragraph 4; or

               (b)  the entering into or amendment of any Ancillary
                    Services Agreement between NGC and any User (or other
                    person) for the provision of Enhanced Reactive Power
                    Service.

               Any such agreement constituting an Ancillary Services
               Agreement or an amendment thereto and which is entered into
               in accordance with the principles contained in sub-paragraph
               5.3 is referred to in this Schedule and the Appendices as a
               "Market Agreement".

          5.2  The coming into effect of a Market Agreement in relation to
               any Generating Unit shall, in respect of that Generating
               Unit, suspend and replace for the duration thereof the
               provisions for payment for the Obligatory Reactive Power
               Service (if applicable) set out or referred to in paragraph
               4.  In such a case, and for the avoidance of doubt, with
               effect from the expiry or termination of the Market
               Agreement, the provisions for payment for the Obligatory
               Reactive Power Service set out or referred to in paragraph 4
               shall in relation to that Generating Unit cease to be
               suspended and shall resume full force and effect.

          5.3  The following principles shall govern the entering into of
               Market Agreements:

               (a)  Relevant Dates

                              twenty weeks and not later than sixteen weeks
                              prior to a Contract Start Day; and

                         (b)  a Tender Period shall be a period of at least
                              eight consecutive weeks, commencing on a date
                              nominated by NGC and ending on a Market Day.

               (b)  Submission of Tender information by NGC

                    (i)  NGC shall, acting reasonably and having regard to
                         the principles contained in this sub-paragraph
                         5.3, compile a package of information for the use
                         of interested parties comprising technical,
                         procedural and contractual requirements,
                         directions and specifications to govern Market
                         Agreements to take effect from the following
                         Contract Start Day.  NGC shall ensure that such
                         requirements, directions and specifications do not
                         conflict with any of the principles contained in
                         this sub-paragraph 5.3 and so far as reasonably
                         practicable do not discriminate between Tenderers.

                         (c)) shall be submitted in accordance with and on
                         the basis of such (if any) reasonable directions
                         given by NGC in the package of information
                         referred to in subparagraph 5.3(b)(i) or otherwise
                         in such manner as may be reasonably specified by
                         NGC from time to time, which directions shall in
                         either case be, so far as reasonably practicable,
                         consistent with the provisions of Appendices 2 and
                         5.

                    (iii) Each Tender comprising prices for and Tendered

                         of the Obligatory Reactive Power Service shall be
                         submitted on the basis that NGC may only select
                         all (and not some) of the prices and Tendered
                         Capability Breakpoints comprised therein.

                    (iv) Save where expressly provided otherwise in a
                         Tender, each Tender comprising terms for the
                         provision of an Enhanced Reactive Power Service
                         shall be treated as having been submitted on the
                         basis that NGC may select all or part only of the
                         Reactive Power capability comprised therein
                         (which, in the case of the Enhanced Reactive Power
                         Service specified in sub-paragraph 1.3(a), shall
                         mean all or part only of the excess capability
                         comprised therein).

                    (v)  All Tenders shall be submitted in respect of
                         periods of whole and consecutive calendar months,
                         to be not less than twelve months and in multiples
                         of six months, to commence on the next following
                         Contract Start Day.  Save where expressly provided
                         otherwise in a Tender, a Tender (whether in
                         relation to the Obligatory Reactive Power Service
                         or an Enhanced Reactive Power Service) shall be
                         treated as having been submitted on the basis that
                         NGC may select all or part only of any period so
                         tendered (in multiples of six months), subject to
                         a minimum period of twelve consecutive months,
                         commencing on the next following Contract Start
                         Day.

               (e)  Qualification and Evaluation of Tenders

                    (i)  Each Tender must satisfy the mandatory
                         qualification criteria set out in Section A of
                         Appendix 6.

                    (ii) NGC shall evaluate and (without prejudice to sub-
                         paragraphs 5.3(d)(iii), (iv) and (v)) select
                         Tenders (or part(s) thereof) on a basis consistent
                         with its obligations under the Act, the
                         Transmission License and this Agreement and,
                         subject thereto, in accordance with the evaluation
                         criteria set out in Section B of Appendix 6.
                         Without limitation, NGC reserves the right to
                         require tests of a Generating Unit or other Plant
                         and Apparatus (or other equipment), on a basis to
                         be agreed with a Tenderer, as part of the
                         evaluation of a Tender.

                   (iii) NGC shall use reasonable endeavours to evaluate
                         Tenders within ten weeks from each Market Day.

               (f)  Entering into of Market Agreements

                    (i)  Having selected a Tender (or part(s) thereof) in
                         accordance with sub-paragraph 5.3(e), NGC shall
                         notify the relevant Tenderer that it wishes to
                         enter into a Market Agreement in respect thereof
                         and that Tenderer and NGC shall each use
                         reasonable endeavours to agree the terms of, and
                         enter into, a Market Agreement in respect thereof
                         as soon as reasonably practicable but in any event
                         not later than 4 weeks prior to the relevant
                         Contract Start Day.  Notwithstanding the
                         foregoing, if a Market Agreement has not been
                         entered into by the date being 4 weeks prior to
                         the relevant Contract Start Day, then either NGC
                         or the Tenderer shall be entitled, provided that
                         it shall have used all reasonable endeavours to
                         agree the terms of, and enter into, the Market
                         Agreement as aforesaid, to notify the other that
                         it no longer wishes to enter into the Market
                         Agreement, whereupon the Tender in question shall
                         be deemed to be withdrawn.

                    (ii) In the event of a deemed withdrawal of a Tender in
                         the circumstances set out in sub-paragraph
                         5.3(f)(i), NGC shall be entitled to re-evaluate
                         and select all or part of any outstanding Tenders
                         in accordance with sub-paragraphs 5.3(c)(i) and
                         (ii) and to notify one or more Tenderers; if, in
                         substitution for the Tender so deemed to be
                         withdrawn, it wishes to enter into a Market
                         Agreement in respect of any other Tender or
                         Tenders (or part(s) thereof).  Following such
                         notification, NGC and each Tenderer in question
                         shall use reasonable endeavours to agree the terms
                         of, and enter into, a Market Agreement prior to
                         the relevant Contract Start Day.

                   (iii) If, in respect of any Tender, a Market Agreement
                         is not entered into by the relevant Contract Start
                         Day, that Tender shall be deemed to be withdrawn.

                    (iv) Save where otherwise provided in this paragraph 5,
                         all Market Agreements must be entered into on the
                         basis of the terms set out in the relevant Tender
                         (or relevant part(s) thereof).

               (g)  Legal Status of Tenders

                    For the avoidance of doubt, a Tender shall not
                    constitute an offer open for acceptance by NGC, and in
                    respect of any Tender or part(s) thereof selected by
                    NGC pursuant to sub-paragraph 5.3(e) or (f), neither
                    the Tenderer in question nor NGC shall be obliged to
                    provide or pay for the Obligatory Reactive Power
                    Service and/or an Enhanced Reactive Power Service upon
                    the terms of that Tender (or the relevant part(s)
                    thereof) unless and to the extent that those terms are
                    incorporated in a Market Agreement subsequently entered
                    into.

               (h)  Publication

                    (i)  Within the six weeks following each Contract Start
                         Day, NGC shall provide to all persons requesting
                         the same the following information:

                         (a)  in respect of all Market Agreements then
                              subsisting, prices and contacted Reactive
                              Power capability on an individual Tender
                              basis relating to the period from the
                              immediately preceding Contract Start Day
                              until the next following Contract Start Day;

                         (b)  in respect of all Ancillary Services
                              Agreements (including Market Agreements)
                              subsisting in respect of the six month period
                              ending on the immediately preceding Contract
                              Start Day (commencing with that ending on 30
                              September, 1998), details of utilisation of
                              Mvarh provided by individual Despatch Units
                              (or, where relevant, Non-Centrally Despatched
                              Generating Units, other Plant and/or
                              Apparatus or other equipment) pursuant to the
                              Obligatory Reactive Power Service and
                              Enhanced Reactive Power Services;

                         (c)  details of the circumstances surrounding any
                              failure by NGC during the preceding six month

                              responsibilities under this paragraph 5 in
                              the circumstances referred to in paragraph 7;
                              and

                         (d)  any other information reasonably considered
                              by NGC to be pertinent to the Tender process,

                         and, to this extent, each party consents to the
                         disclosure by NGC of the information referred to
                         in sub-sub-paragraphs (a) and (b) above in so far
                         as it relates to the provision of the Obligatory
                         Reactive Power Service and (where applicable) an
                         Enhanced Reactive Power Service from its

                         (or other equipment).

                    (ii) Without prejudice to the provision of information
                         pursuant to sub-paragraph 5.3(h)(i), NGC further
                         agrees to use all reasonable endeavours to provide
                         to all persons requesting the same, within the six
                         weeks following each Contract Start Day, estimates
                         of the Mvarh absorption and generation by the NGC
                         Transmission System, where used for the purposes
                         of voltage support, during the preceding six month
                         period (commencing with that ending on 30th
                         September, 1998).

          6.   AMENDMENT AND CONCLUSION OF ANCILLARY SERVICES AGREEMENTS
               ---------------------------------------------------------

          6.1  NGC and each relevant User shall promptly do all such acts
               and execute and deliver such agreements and other
               documentation as may be necessary to amend or conclude the
               relevant Ancillary Services Agreements so as to give effect
               to the provisions of this Schedule and the Appendices as
               amended from time to time.

          6.2  Sub-paragraphs 4.6 and 6.1 shall not require NGC or any User
               to amend or conclude an Ancillary Services Agreement so as
               to give effect to this Schedule and the Appendices if and to
               the extent that, in respect of any Generating Unit, NGC and
               such User shall have expressly agreed in writing that no
               payments shall be made by NGC to such User under an
               Ancillary Services Agreement for the provision of the
               Obligatory Reactive Power Service from that Generating Unit.

          7    STATUTORY AND REGULATORY OBLIGATIONS
               ------------------------------------

          7.1  No Party shall be bound to perform any of its duties or
               responsibilities under this Schedule and the Appendices
               (including without limitation with regard to the amending or
               concluding of Ancillary Services Agreements in accordance
               with sub-paragraph 4.6 and the entering into of Market
               Agreements in accordance with paragraph 5) if and to the
               extent that to do so would be likely to involve that Party
               in breach of its duties and obligations (if any) under the
               Act or of any condition of a License.  Accordingly, nothing
               in this Schedule and the Appendices shall preclude NGC from
               procuring the provision of any Enhanced Reactive Power
               Service in a manner otherwise than in accordance with
               paragraph 5 in order to comply with its duties and
               obligations under the Act and/or any condition of the
               Transmission License to the extent such compliance cannot
               reasonably be assured by the performance of its duties and
               responsibilities under paragraph 5.

          7.2  Without prejudice to sub-paragraph 7.1, NGC shall not be
               bound to comply with the provisions of sub-paragraph 5.3(h)
               with regard to the disclosure of information to the extent
               that to do so would be likely to restrict, distort or
               prevent competition in the provision of the Obligatory
               Reactive Power Service and/or Enhanced Reactive Power
               Services.

                                                  Despatch Unit]

               where, subject always to paragraphs 7 and 8 below:

               PU   =    the utilisation payment in respect of a Despatch
                         Unit for a Settlement Period determined in
                         accordance with paragraph 2 below; and

               PC   =    the capability payment in respect of a Despatch

                    As soon as reasonably practicable following the expiry
                    of each twelve month period ending 31st March, NGC
                    shall recalculate ZWF [lead] ZWF [lag] for that twelve
                    month period in accordance with the above provisions
                    for calculation of the Provisional Zonal Weighting
                    Factors but substituting for the Total Forecast
                    Capability the actual total leading or lagging (as the
                    case may be) Mvar capability for that twelve month
                    period in each Relevant Zone as determined by NGC ("the
                    Total Actual Capability").  Such recalculation of ZWF
                    [lead] and ZWF [lag] shall be undertaken by NGC in a
                    manner consistent with the principles and methodologies
                    set out in the document entitled "Methodology Document
                    for the Recalculation of Zonal Weighting Factors"

                    Weighting Factors"), together with the Total Actual
                    Capability, shall be published by NGC in the Seven Year
                    Statement.  Each Final Zonal Weighting Factor (both
                    leading and lagging) shall not in any event be greater
                    than 3,000 and (for the avoidance of doubt) no
                    determination of ZWF [lead], ZWF [lag] and TAN shall be
                    made in respect of any such twelve month period when
                    Y=O.

                    NGC shall derive the Total Actual Capability from the
                    Mvar capability (required under and in accordance with
                    the Connection Conditions of the Grid Code) of
                    Generating Units in respect of which Ancillary Services

                    give effect to the provisions of sub-paragraphs 4.2 and
                    4.3 of this Schedule.  In respect of any twelve month
                    period ending 31st March, such Mvar capability shall be
                    reduced pro rata for all Settlement Periods in such
                    twelve month period in respect of which no capability
                    payments referred to in this Appendix 1 shall fall due:

                         question); and

                         the twelve month period in question); and

                    (c)  by virtue of factor J referred to in paragraph 3
                         above being set to zero (at any time during the
                         twelve month period in question).

                    As soon as reasonably practicable following publication
                    of the relevant Seven Year Statement, NGC shall pay to
                    each relevant User or be paid by each relevant User
                    such sum as will reconcile:

                    (i)  capability payments made to that User and
                         calculated in accordance with paragraph 3 above by
                         reference to the Provisional Zonal Weighting
                         Factors;

                    with

                    (ii) capability payments due to or from that User and
                         calculated in accordance with paragraph 3 above by
                         reference to the Final Zonal Weighting Factors.

                    For the avoidance of doubt, such reconciliation will
                    include the payment of interest at the Base Rate from
                    the date of payment by NGC to that User of the
                    capability payments referred to at (i) above.

                    For clarification purposes, each reference in this
                    paragraph 4 to "need" does not imply actual Reactive
                    Power need but is used merely to refer to the figure
                    identified as "need" in the Seven Year Statement.  Such
                    figure shall be determined each year using the same
                    principles and methodologies as used to determine the
                    zonal weighting factors for the twelve month periods
                    ended on 31st March, 1996 and 31st March, 1997.

          5    INDEXATION
               ----------

               The indexation factor I used in the formulae in paragraphs 2
               and 3 above shall, with effect from 1st October, 1997 in
               respect of the period from (and including) that date to (and
               including) 31st March, 1998, and with effect from 1st April
               in respect of each subsequent twelve month period ending
               31st March, be determined as follows:

               I    =              RPI[2]
                                   ------
                                   RPI[1]

               Where

               For the period from (and including) 1st October, 1997 to
               (and including) 31st March, 1998 RPI[2] = 155.4, and
               thereafter RPI[2] is the RPI for March of the immediately
               preceding twelve month period ending 31st March.

               RPI[1] is the RPI for March, 1994 (142.5).

               The index used is the Retail Prices Index (RPI) with 1987 =
               100 base.  The source of the RPI index is the monthly
               Department of Employment "Employment Gazette".

               In the event that RPI ceases to be published or is not
               published in respect of any relevant month or it is not
               practicable to use RPI because of a change in the method of
               compilation or some other reason, the indexation factor I
               shall be calculated by NGC using an alternative index
               nominated by NGC as it thinks fit acting reasonably but with
               a view to determining the relevant payment after indexation
               that would be closest to the relevant payment after
               indexation if RPI had continued to be available.

               Subject always to sub-paragraph 2.5 of this Schedule, in
               respect of all periods from (and including) 1st April, 2001
               the indexation factor I applicable for the period from (and
               including) 1st April, 2000 to (and including) 31st March,
               2001 shall apply.

          6    INFORMATION UNAVAILABLE
               -----------------------

               Where any information or data required by NGC for the
               calculation of payments to be made pursuant to this Schedule
               for any 12 month period ending 31st March is not available
               to NGC at the relevant time, NGC shall calculate payments
               for that 12 month period based upon the amounts payable to
               Users for the immediately preceding 12 month period adjusted
               by NGC to reflect its best estimate of the unavailable
               information or data.  Once such information or data is
               available, NGC shall accordingly make all consequential
               adjustments to the payments from itself to Users as soon as
               reasonably practicable thereafter to reflect any repayment
               or additional payment so required to be made by one party to
               the other in respect of the period from 1st April in such
               year until the date of such repayment or additional payment
               (including interest thereon at the Base Rate).

          7    COMMISSIONING
               -------------

          7.1  Save in relation to Despatch Units operational prior to 1st
               April, 1997, no utilisation or capability payments referred
               to in this Appendix 1 shall fall due and payable to any User
               in respect of any Despatch Unit until the Settlement Period
               in which it is demonstrated to the reasonable satisfaction
               of NGC, having regard to industry practice, that the
               Despatch Unit (or, in or the case of a Centrally Despatched
               CCGT Module, but subject always to sub-paragraph 7.4 below,
               each relevant CCGT Unit) complies with the provisions of
               Grid Code CC6.3.2 and CC6.3.4 or (where NGC in its sole
               discretion requires Reactive Power from a Despatch Unit
               before then for the purposes of security of the NGC
               Transmission System) such earlier date as NGC may agree with
               a User in respect of that Despatch Unit.

          7.2  Before any demonstration of compliance referred to in sub-
               paragraph 7.1 above, it shall be necessary for the User to
               demonstrate to NGC's reasonable satisfaction, having regard
               to industry practice, that the Despatch Unit's (or, in the
               case of a Centrally Despatched CCGT Module, each relevant
               CCGT Unit's) Excitation system, and in particular the Under-
               excitation Limiter, has been successfully commissioned and
               complies with the provisions of Grid Code CC6.3.8.

          7.3  For the avoidance of doubt, the issue by NGC in relation to
               a Despatch Unit of a Despatch Instruction to unity power
               factor or zero Mvar shall neither imply by itself that NGC
               is reasonably satisfied with compliance as referred to in
               sub-paragraph 7.1 above nor imply in relation to the
               Despatch Unit agreement by NGC of an earlier date as also
               referred to therein.

          7.4  Until such time as it shall be demonstrated to the
               reasonable satisfaction of NGC that, in relation to a
               Centrally Despatched CCGT Module, all relevant CCGT Units
               comply with the provisions of Grid Code CC6.3.2 and CC6.3.4
               as referred to in sub-paragraph 7.1 above, it is the
               intention that capability and utilisation payments shall
               fall due to a User in respect of that Centrally Despatched
               CCGT Module notwithstanding the provisions of sub-paragraph
               7.1 above but on the basis that capability payments will be
               calculated by reference to the Reactive Power capability of
               each CCGT Unit in respect of which compliance has been
               demonstrated.  For such period, and in relation to that
               Centrally Despatched CCGT Module only, this Appendix 1 and
               the definition of QC and QR set out in Appendix 3 shall be
               read and construed accordingly.

          8    DE-ENERGISATION, DECOMMISSIONING AND DISCONNECTION
               --------------------------------------------------

               Subject to all rights and obligations of NGC and the User
               accrued at such date, utilisation and capability payments
               referred to in this Appendix 1 shall cease to fall due and
               payable to any User in respect of any Despatch Unit with
               effect from the date of expiry or termination for whatever
               reason of the relevant Ancillary Services Agreement in
               accordance with its terms or (if earlier) with effect from
               the date of De-energisation, Decommissioning or
               Disconnection of that Despatch Unit for any reason pursuant
               to the relevant Supplemental Agreement or this Agreement.

          9    RECONCILIATION
               --------------

               As soon as practicable after this Schedule has taken effect
               and Ancillary Services Agreements have been amended so as to
               give effect thereto, NGC will pay to each relevant User or
               be paid by each relevant User such sum as will reconcile:

               (a)  payments (if any) made to such User for the provision
                    of the Obligatory Reactive Power Service from Despatch
                    Units in respect of the period from 1st October, 1997
                    to (and including) the date of such reconciliation by
                    NGC

                    with

               (b)  payments due to or from such User pursuant to any
                    Ancillary Services Agreements giving effect to this
                    Schedule in respect of the period from 1st October,
                    1997 to the date of such reconciliation (both dates
                    inclusive) as if such Ancillary Services Agreements had
                    then been effective.

               For the avoidance of doubt, such reconciliation will include
               the payment of interest at Base Rate from the date of the
               relevant payment by NGC referred to at sub-paragraph 9(a)
               above.

               AND ENHANCED REACTIVE POWER SERVICES - MARKET MECHANISM
               --------------------------------------------------------

          The provisions of this Appendix 2, as referred to in sub-
          paragraph 5.3(d)(i) of this Schedule, shall apply to the
          calculation of payments in respect of Tenders comprising prices
          for and Tendered Capability Breakpoints relating to the
          Obligatory Reactive Power Service and in respect of Tenders
          comprising terms for the provision of the Enhanced Reactive Power
          Service specified in sub-paragraph 1.3(a) of this Schedule, in
          each case in respect of Despatch Units.  All payments shall be
          expressed in pounds sterling.  All algebraic terms contained in
          this Appendix 2 shall bear the meanings set out in paragraph 1
          below unless the context otherwise requires.

          1.   DEFINITIONS
               -----------

               For the purposes of this Appendix 2, unless the context
               otherwise requires, the following terms shall have the

               Settlement Period per Despatch Unit)

               where, subject always to paragraphs 6, 7 and 8 below:

               PUM  =    the utilisation payment in respect of a Despatch
                         Unit for a Settlement Period determined in
                         accordance with paragraph 3 below;

               PCA  =    the available capability payment in respect of a
                         Despatch Unit for a Settlement Period determined
                         in accordance with paragraph 4 below; and

                         a Despatch Unit for a Settlement Period determined
                         in accordance with paragraph 5 below.

               Provided always that PTM shall be 0 in all Settlement
               Periods from and including that in which:

               (a)  the relevant Despatch Unit (or, in relation to a
                    Centrally Despatched CCGT Module, any relevant CCGT
                    Unit) fails a Reactive Test or a Contract Test until
                    (and including) the Settlement Period in which a
                    subsequent Reactive Test or Contract Test (as the case
                    may be) is passed in relation to that Despatch Unit (or
                    CCGT Unit (as the case may be)); or

               (b)  the User fails (other than pursuant to an instruction
                    given by NGC or as permitted by the Grid Code) to set
                    the Automatic Voltage Regulator of the Despatch Unit
                    (or, in relation to a Centrally Despatched Module, any
                    relevant CCGT Unit) to a voltage following mode until
                    (and including) the Settlement Period in which the User
                    notifies NGC that the Automatic Voltage Regulator is so
                    set; or

               (c)  the Despatch Unit fails to comply with a Reactive
                    Despatch Instruction due to the fact that the Despatch
                    Unit (or, in relation to a Centrally Despatched CCGT
                    Module, any relevant CCGT Unit) is unable to increase
                    and/or decrease its Mvar Output (other than as a direct
                    result of variations in System voltage) until (and
                    including) the Settlement Period in which the User
                    notifies NGC that the Despatch Unit is so able to
                    comply; or

               (d)  the Despatch Unit fails to have a Mvar range which
                    includes the ability to provide zero Mvar at the
                    Commercial Boundary until (and including) the
                    Settlement Period in which the User notifies NGC that
                    the Despatch Unit has or once more has such range.

                                      APPENDIX 5
                                      ----------

                                SUBMISSION OF TENDERS
                                ---------------------

          The provisions of this Appendix 5 specify the manner in which
          Users shall complete Tenders comprising prices and Tendered
          Capability Breakpoints relating to the Obligatory Reactive Power
          Service and terms for the provision of the Enhanced Reactive
          Power Service specified in sub-paragraph 1.3(a) of this Schedule,
          in each case in respect of Despatch Units.

          A Tender shall include (inter alia) details of the Reactive Power
          range, the prices tendered for utilisation and capability and an
          indexation mechanism as set out below.  Each Tender must relate
          to one Despatch Unit only.  Users wishing to tender in relation
          to more than one Despatch Unit must therefore submit separate
          Tenders for each Despatch Unit.

          1    REACTIVE POWER CAPABILITY
               -------------------------

          1.1  In respect of each Despatch Unit, a Tenderer must nominate a
               Genset Registered Capacity which it anticipates will be the
               actual Genset Registered Capacity on the Contract Start Day
               for that Despatch Unit (in this Appendix 5 referred to as
               "the Nominated Genset Registered Capacity") to be used for
               the duration of the Market Agreement.  All capability data
               used for the purpose of a Tender must be expressed as the
               capability of a Despatch Unit at the Commercial Boundary and
               must represent the value of Reactive Power output which can
               be supplied continuously at the Commercial Boundary when the
               Despatch Unit is operating at the Nominated Genset
               Registered Capacity.

          1.2  In respect of each Despatch Unit, all capability data
               relating to the provision of the Enhanced Reactive Power
               Service specified in sub-paragraph 1.3(a) of this Schedule
               must be expressed as the capability of that Despatch Unit at
               the Commercial Boundary across a system voltage range to be
               specified by the Tenderer in its Tender (or otherwise in
               accordance with directions given by NGC).

          1.3  All Reactive Power capability data in respect of a Despatch
               Unit must be expressed as positive, whole numbers in Mvar,
               with leading and lagging capability data distinguished by
               the subscripts [lead] and [lag].

          1.4  In respect of each Despatch Unit, and subject to any
               directions issued from time to time by NGC with regard to
               such values, the User must submit at least one Reactive
               Power capability value and may in addition submit up to a
               further two Reactive Power capability values (all three
               being "Tendered Capability Breakpoints"), for both leading
               and lagging Mvar.  One of these Tendered capability
               Breakpoints, in respect of both leading and lagging Mvar,
               must be equivalent to the minimum Reactive Power capability
               of a Despatch Unit which a User is obligated to provide
               under and in accordance with the Connection Conditions of
               the Grid Code (to the nearest whole Mvar) after application
               of the principles set out in sub-paragraphs 1.1 and 1.2
               above and as further described in the package of information
               referred to in sub-paragraph 5.3(b)(i) of this Schedule.

          1.5  The Tendered Capability Breakpoints shall be defined for the
               purposes of this Appendix as TQ1, TQ2, TQ3, for leading and
               lagging Mvar as the case may be, where:

                    TQ3[lead] >TQ2[lead] >TQ1[lead] >0

               and  TQ3[lag] >TQ2[lag] >TQ1[lag] >0

          1.6  Where only two Tendered Capability Breakpoints are tendered,
               for leading or lagging Mvar as the case may be, then the
               value of TQ3 shall be deemed to be null for the purposes of
               calculating payments for capability and utilization and no
               additional payments for capability will fall due and payable
               in respect of a Despatch Unit for the provision of Reactive
               Power capability above Tendered Capability Breakpoint TQ2.

          1.7  Where only one Tendered Capability Breakpoint is tendered,
               for leading or lagging Mvar as the case may be, then the
               values of TQ2 and TQ3 shall be deemed to be null for the
               purposes of calculating payments for capability and
               utilisation and no additional payments for capability will
               fall due and payable in respect of a Despatch Unit for the
               provision of Reactive Power capability above Tendered
               Capability Breakpoint TQ1.

          1.8  The Reactive Power capability value at zero Mvar (referred
               to in paragraph 2 below as Q0) shall be treated as a
               Tendered Capability Breakpoint for the purposes of tendering
               capability and utilisation prices and calculating capability
               and utilisation payments.

               1.1  in relation to a Tender for provision of the Enhanced
                    Reactive Power Service specified in sub-paragraph
                    1.3(a) of this Schedule, the leading and/or lagging
                    capability (as the case may be) comprised therein,
                    being the capability in excess of that required under
                    and in accordance with the Connection Conditions of the
                    Grid Code, must be at least 15 Mvar leading and/or 15
                    Mvar lagging (as the case may be) or (if lower) such
                    amount of Mvar representing an additional 10% of that
                    required under and in accordance with the Connection
                    Conditions of the Grid Code (in each case as measured
                    at the Commercial Boundary); and

               1.2  in relation to a Tender for provision of any other
                    Enhanced Reactive Power Service, the leading and/or
                    lagging capability (as the case may be) comprised
                    therein must be at least 15 Mvar leading and/or 15 Mvar
                    lagging (as the case may be) (as measured at the

               1.3  the tendered capability must be subject to Mvar
                    metering meeting the requirements of Appendix 4; and

               1.4  the tendered capability must be subject to Mvar
                    despatch facilities reasonably acceptable to NGC,
                    incorporating the ability for NGC to receive from the
                    Tenderer relevant technical, planning and other data in
                    NGC's reasonable opinion necessary in connection
                    therewith; and

               1.5  the site in question must be the subject of an
                    agreement for connection to, and/or use of, the NGC
                    Transmission System or (as the case may be) a
                    Distribution System.

          SECTION B - EVALUATION CRITERIA
          -------------------------------

          2    The overall economic value of a Tender (and where
               appropriate any part thereof) will be assessed by reference
               to the following criteria (which are not listed in any order
               of importance or priority):

               2.1  in relation to a Generating Unit providing the
                    Obligatory Reactive Power Service, a comparison with
                    the default payment arrangements for that Generating
                    Unit, including the effect (if any) of the balance of
                    tendered capability and utilisation prices as a hedge
                    against forecast costs of that Generating Unit pursuant
                    to the default payment arrangements;

               2.2  the location of the tendered capability and its
                    effectiveness in providing voltage support for the NGC
                    Transmission System;

               2.3  its interaction with other Tenders, in terms (inter
                    alia) of relative prices and capability tendered and
                    relative effectiveness in providing voltage support as
                    referred to in sub-paragraph 2.2 above;

               2.4  forecast savings (if any) in constraint costs resulting
                    from the consequential effect on power flows; and

               2.5  and forecast benefit or detriment attributable to it in
                    the context of the investment planning process referred
                    to at paragraph 4 below.

          3    Particular factors affecting the value of a Tender (and
               where appropriate any part thereof) may include (without
               limitation) the following evaluation criteria (which are not
               listed in any order of importance or priority):

               3.1  the amount of leading and lagging Mvar tendered and the
                    impact (if any) of any changes in the technical data,

               3.4  forecast Mvarh output, including any revised forecast
                    of Mvarh output taking into account tendered
                    utilisation prices (for the avoidance of doubt of the
                    Tender and of all other Tenders pursuant to sub-
                    paragraph 2.3 above);

               3.5  in relation to a Generating Unit, forecast MW output
                    and MW availability;

               3.6  the expected availability and quality of capability
                    tendered, in terms of reliability and dependability for
                    despatch purposes, derived from:

                    (i)  historical performance (where relevant);

                    (ii) expected reliability of capability tendered
                         signalled by tendered prices;

                   (iii) any programme agreed with NGC for the restoration
                         of capability;

               3.7  the availability of suitable monitoring facilities;

               3.8  the capability (if any) of a Generating Unit to provide
                    voltage support services when not providing Active
                    Power (for example pumped storage plant operating in
                    spin-gen mode or when pumping and open cycle gas
                    turbine plant when declutched and operating in
                    Synchronous Compensation mode);

               3.9  the complexity of the terms offered within the Tender;

               3.10 the results of any testing carried out pursuant to sub-
                    paragraph 5.3(e)(ii) of this Schedule and (where
                    applicable) the absence of any such testing; and

               3.11 any other factors enhancing or constraining the
                    capability tendered, derived (inter alia) from
                    technical and other information made available to NGC
                    (including without limitation operational and planning
                    data provided to NGC pursuant to the Grid Code).

          4.   For the avoidance of doubt, Tenders will be considered in
               the investment planning process of NGC's Transmission
               Business only if, and to the extent, required to enable NGC
               to comply with its obligations under the Act and the
               Transmission License, and in such a case any consequential
               benefit or detriment attributable to the Tender will be
               taken into account in the tender evaluation process and
               Tenders will be evaluated accordingly.

          5.   For the avoidance of doubt:

               (a)  extant voltage support for the NGC Transmission System
                    whether via contracted services from third parties or
                    assets owned and/or operated by NGC's Transmission
                    Business; and

               (b)  forecast Mvarh Demand on the NGC Transmission System
                    and at Grip Supply Points;

               in each case as at the relevant Market Day and as
               anticipated by NGC at the subsequent Contract Start Day and
               throughout the term of the Tender, will be taken into
               account in the tender evaluation process and Tenders will be
               evaluated accordingly.

                     paragraph 1 of
                     Appendix 8 upon
                     which the totality
                     of payments referred

                     and founded.

                Applicable principle:

                That, to the extent
                innovation in the
                development of the
                default payment
                arrangements or the
                giving of appropriate
                economic signals is not
                thereby stifled, the
                specific costs from time
                to time identified in
                paragraph 1 of Appendix 8
                (and upon which the
                totality of payments
                referred to therein is
                based and founded) should
                continue to comprise the
                totality of variable
                costs (actual or
                estimated) incurred or to
                be incurred in respect

                Units providing
                Obligatory Reactive Power
                Service, provided always
                that each of those
                specific costs from time
                to time identified shall
                only be a variable cost
                not recovered under the
                Pooling and Settlement
                Agreement which:

                (i)  is not being
                     incurred at the date
                     this Schedule comes
                     into effect; or

                (ii) is being incurred at
                     the date this
                     Schedule comes into
                     effect and as at
                     that date is either
                     identified as a
                     specific cost in
                     paragraph 1 of
                     Appendix 8 or is
                     being recovered
                     under the Pooling
                     and Settlement
                     Agreement.

                                      ----------

                                 CHARGING PRINCIPLES
                                 -------------------

          In accordance with the relevant provisions of this Schedule, the
          following principles are intended to form the basis of the
          default payment arrangements for the provision of the Obligatory
          Reactive Power Service set out in this Schedule and are intended
          to be taken into account in any review of the indexation factor
          referred to in Appendix 1.  However, they are not intended to
          stifle innovation in the development of default payment
          arrangements or the giving of appropriate economic signals.  It
          is therefore the Parties' intention that, upon any change in the
          nature of, or extent of recovery under the Pooling and Settlement
          Agreement of, variable costs (actual or estimated) incurred or to
          be incurred by Generating Units providing the Obligatory Reactive
          Power Service, the specific costs identified in paragraph 1 below
          shall be a matter for review by the Transmission Users Group as
          more particularly referred to as item 5 of Appendix 7.

          1.   The totality of payments that would be made pursuant to the
               default payment arrangements in the absence of Market
               Agreements shall be based and founded upon the following
               variable costs (actual or estimated) incurred or to be
               incurred in respect of, and aggregated across, all
               Generating Units providing the Obligatory Reactive Power
               Service:

               1.1  the additional heat losses incurred as a consequence of
                    producing Reactive Power, measured at the high voltage
                    side of the generator/transformer terminals, the
                    calculation of such heat losses to take account of the
                    square law relationship between the electric current
                    and the additional heat losses incurred; and

               1.2  maintenance costs incurred as a direct result of
                    Reactive Power output (including a sum in respect of
                    any reduction in the working life of generating unit
                    components consequent upon Reactive Power output).

          2.   For the avoidance of doubt, and without limitation, the
               totality of payments referred to in paragraph 1 above shall
               not take into account in respect of any Generating Unit
               providing the Obligatory Reactive Power Service the fixed
               costs incurred in achieving initial compliance with the
               relevant provisions of the Grid Code.

          3.   Further for the avoidance of doubt, the totality of payments
               referred to in paragraph 1 above shall, to the extent
               affecting the specific costs therein identified, take due
               account of any change in or amendments to, or replacement
               of, the Pooling and Settlement Agreement, the Grid Code and
               any other statutory or regulatory obligation, in each case
               coming into force or effect after 1st October, 1997 and
               affecting the provision of the Obligatory Reactive Power
               Service.

                    to comply with the order.
          17.4 NGC Transmission Licence
               ------------------------
               If a breach of the nature referred to in Sub-Clause 17.1
               continues to the extent that it places or seriously
               threatens to place in the immediate future NGC in breach of
               the NGC Transmission Licence, NGC may De-Energise the User's
               Equipment upon the expiry of at least 12 hours prior written
               notice to the User, provided that at the time of expiry of
               such notice the breach concerned remains unremedied.
          17.5 Re-Energisation Disputes
               ------------------------
               If, following any de-Energisation pursuant to this Clause
               17, the User applies to NGC for the User's Equipment to be
               Re-Energised and is refused or is offered terms which the
               User does not accept, this shall be recognised as a dispute
               over the terms for connection and use of system which the
               User may refer to the Director for determination under the
               NGC Transmission Licence.  If the User accepts any terms
               offered by NGC or settled by the Director pursuant to any
               such reference, NGC shall Re-Energise the User's Equipment
               forthwith after any request from the User for NGC to do so.
          17.6 Event of Default
               ----------------
               If the breach which led to any De-Energisation pursuant to
               this Clause 17 remains unremedied at the expiry of at least
               6 months after the date of such De-Energisation, NGC may
               declare by notice in writing to the User that such breach
               has become an event of default provided that:
               (a)       all disputes arising out of the subject-matter of
                         this Clause 17 which are referred to the Dispute
                         Resolution Procedure have then been finally
                         determined in favour of NGC; and
               (b)       any reference to the Director pursuant to sub-
                         clause 17.5 has then been finally determined in
                         favour of NGC or any terms settled by the Director
                         pursuant to such application have not been
                         accepted by the User.
          17.7 Disconnection
               -------------
               Once NGC has given a valid notice of an event of default
               pursuant to Sub-Clause 17.6 NGC may give notice of
               termination to that User whereupon this Supplemental
               Agreement shall terminate and:
               (i)       NGC shall Disconnect all the User's Equipment at

                                   which forms part of such Trading Site;
                                   and

                         (ii)      the average Demand within the Trading
                                   Site (other than Station Demand) to be
                                   supplied by the Power Station in (i)
                                   above for each of the number of peak
                                   half hours notified by the User to NGC
                                   pursuant to paragraph 2.1;

                         (iii)     the Station Demand for the Power Station
                                   within the Trading Site determined in
                                   accordance with paragraph 1.1.2(c)(i);

                    for the period as notified by NGC to the User under
                    paragraph 2.1 and NGC shall use such forecasts as the
                    basis of Transmission Network Use of System Charges for
                    such Financial Year.

          1.1.3     Variation of Charges by NGC during the Financial Year
                    -----------------------------------------------------

                    The User shall notify NGC of any revision to the
                    forecast Demand submitted by the User under paragraph
                    1.1 of this Appendix E at least quarterly or at such
                    other intervals as may be agreed between NGC and the
                    User from time to time.  NGC shall revise the
                    Transmission Network Use of System Charges payable by
                    the User to take account of any such revised forecast
                    provided in accordance with this paragraph 1.1.3, NGC
                    shall commence charging the varied Transmission Network
                    Use of System Charges from the first day of the month
                    following the month in which such revised forecast was
                    received provided always that such forecast is provided
                    before 15th day of such month.

          1.2       Reconciliation Statements
                    -------------------------

                    Initial Reconciliation Statements
                    ---------------------------------

          1.2.1     On or before 1 March in each Financial Year NGC shall
                    promptly calculate on the basis set out in the
                    statement published by NGC in accordance with Licence
                    Condition 10 of the Transmission Licence the Demand
                    related or Generation related Transmission Network Use
                    of System Charges (as the case may be) that would have
                    been payable by the User during each month during that
                    Financial Year in respect of the forecasts which had
                    previously been provided by the User in accordance with
                    paragraph 1.1 (the "Actual Amount").  NGC shall then
                    compare the Actual Amount with the amount of Demand
                    related or Generation related Transmission Network Use
                    of System Charges (as the case may be) paid during each
                    month during that Financial Year by the User (the
                    "Notional Amount").

          1.2.2     As soon as reasonably practicable and in any event by
                    1st March in each Financial Year NGC shall then prepare
                    an initial reconciliation statement and send it to the
                    User.  Such statement shall specify the Actual Amount
                    and the Notional Amount for each month during the
                    relevant Financial Year and, in reasonable detail, the
                    information from which such amounts were derived and
                    the manner in which they were calculated.

          1.2.3     Together with the initial reconciliation statement NGC
                    shall issue a credit note in relation to any sum shown
                    by the reconciliation statement to be due to the User
                    or an invoice in respect of sums due to NGC and in each
                    case interest thereon calculated pursuant to paragraph
                    1.2.5 below.

          1.2.4     Invoices issued under paragraph 1.2.3 above and 1.2.5
                    below shall be payable on or before 31st March in the
                    Financial Year to which they relate.

          1.2.5     In respect of the Financial Year:

                    (a)  the User shall, following receipt of an
                         appropriate invoice, pay to NGC an amount equal to
                         the amount (if any) by which the aggregate Actual
                         Amount exceeds the aggregate Notional Amount; and

                    (b)  NGC shall issue the User with a credit note for an
                         amount equal to the amount (if any) by which the
                         aggregate Notional Amount exceeds the aggregate
                         Actual Amount.

                    Interest shall be payable by the paying Party to the
                    other on such amounts from the date of payment
                    applicable to the month concerned until the date of
                    actual payment of such amounts and such interest shall
                    be calculated on a daily basis at a rate equal to the
                    Base Rate during such period.

                    Final Reconciliation Statements
                    -------------------------------
          1.2.6     (a)  NGC shall as soon as reasonably practicable after
                         the end of each Financial Year issue a further
                         reconciliation statement in respect of
                         Transmission Network Use of System Charges payable
                         in respect of each month of that Financial Year
                         showing:
                         (i)       any change in the Transmission Network
                                   Use of System Charges from those
                                   specified in the initial reconciliation
                                   statement provided in accordance with
                                   paragraph 1.2.1 above;

                         (ii)      whether the change represents a
                                   reconciliation payment owing by NGC to a
                                   User or by a User to NGC;

                         (iii)     the amount of interest determined in
                                   accordance with 1.2.5 above;

                         (iv)      the information from which the amounts
                                   in (i) above are derived and the manner
                                   of their calculation.

                    (b)  The provisions of paragraph 1.2.3 and 1.2.5 shall
                         apply mutatis mutandis to sums specified in the
                         Final Reconciliation Statement.

          2.   Revision of Charges
               -------------------

          2.1  To the extent permitted by the Transmission Licence and this
               Agreement NGC may revise its Connection Charges and
               Transmission Network Use of System Charges or the basis of
               their calculation including issuing revisions to Appendices
               A, B, C, and D (or D1 if appropriate) hereto.  On or before
               31st October in each Financial Year NGC shall notify the
               User in writing of the intended basis of calculation to be
               used by NGC in the following Financial Year together with
               time periods over which the data required to be provided
               pursuant to paragraph 1 of this Appendix E is required and
               shall consult with the User concerning the same.  On or
               before 30th November in each Financial Year NGC shall
               confirm to the User the basis of calculation to be used in
               the following Financial Year.

          2.2  NGC shall give the User not less than 2 months prior written
               notice of any revised charges, including revisions to
               Appendices A, B, C and D (or D1 if appropriate) hereto,
               which notice shall specify the date upon which such
               revisions become effective (which may be at any time).  The
               User shall pay any such revised charges and Appendix A, B,
               C, D (and/or D1 as appropriate) shall be amended
               automatically (and a copy sent to the User) to reflect any
               changes to such Appendices with effect from the date
               specified in such notice.

          2.3  Subject to the provisions of paragraph 3.2 below if in the
               reasonable opinion of NGC any development, replacement,
               renovation, alteration, construction or other work to the
               NGC Transmission System or termination of a Supplemental
               Agreement by another User or an alteration to the
               requirements of the User or any other User means that to
               ensure that NGC is charging in accordance with the
               provisions of the Statement pursuant to Condition 10 of the
               Transmission Licence NGC needs to vary the Connection
               Charges payable by the User in relation to the Connection
               site then NGC shall have the right to vary such charges
               accordingly upon giving to the User not less than 2 months
               prior written notice.  Such notice shall be deemed to be a
               revised connection Offer and before any such variation
               becomes effective the provisions of Sub-clauses 11.3 to 11.4
               of the Master Agreement shall apply mutatis mutandis.
               Following any such variation the provisions of Appendices A
               and B shall be amended automatically (and a copy sent to the
               User) to reflect such variation with effect from the date
               such variation comes into effect.

          3.   REPLACEMENT OF NGC ASSETS
               -------------------------

          3.1  Appendix A specifies the age of the NGC Assets at the
               Connection Site at the date of this Supplemental Agreement.
               NGC Connection Charges are calculated on the assumption that
               NGC Assets will not require replacement until the expiry of
               the Replacement Period applicable to each NGC Asset
               concerned and such period has been agreed between NGC and
               the User.

          3.2  Where in NGC's reasonable opinion an NGC Asset requires
               replacement before the expiry of its Replacement Period NGC
               shall, with the prior written approval of the User (except
               where in NGC's reasonable opinion such replacement is
               necessary in which case such approval shall not be required
               but in such case the User shall have the right to
               Disconnect) have the right to replace the NGC Asset at no
               additional cost to the User until expiry of its original
               Replacement Period.  Upon expiry of such original
               Replacement Period NGC shall be entitled to vary the
               Connection Charges in respect of the replaced NGC Asset so
               that they are calculated on the basis of the then Net Asset
               Value of such NGC Assets.  NGC shall give the User not less
               than 2 months prior written notice of such varied charges
               which notice shall specify the date upon which such increase
               or reduction (as the case may be) becomes effective.  The
               User shall pay such varied charges and Appendices A and B
               shall be amended automatically (and a copy sent to the User)
               to reflect such revised charges with effect from the date
               specified in such notice.

          3.3  Upon the expiry of the Replacement Period of any NGC Asset:

               (a)  (i)       if in NGC's reasonable opinion to enable NGC
                              to comply with its licence and statutory
                              obligations it is necessary to replace such
                              NGC Asset; or

                    (ii)      if such NGC Asset is to be left in service
                              then NGC shall give written notice of this
                              and that it will, unless within 3 months of
                              the receipt of such notice the User objects
                              in writing to the proposal, replace or retain
                              (as the case may be) such NGC Asset.

               (b)  the User may request that NGC replaces the Asset.

          3.4  Where the User serves a counter notice pursuant to paragraph
               3.3 above then NGC shall:

               (a)  keep the NGC Asset in service; and

               (b)  negotiate with the User in good faith with regard to
                    the Connection Charges applicable to such NGC Asset.

               In the event that NGC and the User fail to agree the level
               of such Connection Charges in accordance with paragraph
               3.4(b) above then the User shall pay Connection Charges to
               NGC in respect of such NGC Asset equal to the Connection
               Charges payable by the User in respect of the NGC Asset in
               the last Financial Year of the Replacement Period (the
               "Deemed Charge") and the matter shall be referred to the
               Director for determination.  If the Director determines that
               the Connection Charges payable in respect of such NGC Asset
               should be:

               (i)  less than the Deemed Charge then NGC shall repay to the
                    User the difference between the Deemed Charge and the
                    amount so determined by the Director together with
                    interest at the Base Rate, for the period from when the
                    User started to pay the Charge until the date of
                    payment;

               (ii) greater than the Deemed Charge then the User shall pay
                    the difference to NGC with interest at the Base Rate
                    for the period from when the User started to pay the
                    Deemed Charge until the date of payment.

          3.5  Where the Connection Charges are payable in respect of NGC
               Assets:

               (a)  replaced in accordance with paragraph 3.3 above; or

               (b)  retained in accordance with paragraph 3.3 above; then
                    NGC shall except in the circumstances in paragraph
                    3.4(b) give the User not less than 2 months prior
                    written notified of such varied charges and specify the
                    date upon which such charges become effective.  The
                    User shall pay such varied charges and Appendices A and
                    B shall be amended automatically (and a copy sent to
                    the User) to reflect such revised charges with effect
                    from the dates notified to the User by NGC.  Where NGC
                    is in negotiation with the User in accordance with
                    paragraph 3.4(b) then it shall give such notice as is
                    reasonably practicable in the circumstances.

          4    Termination Amounts
               -------------------

          4.1  The expressions set out below shall have the meanings shown:

                                             the figure expressed as a
                                             percentage appearing in the
                                             column headed Allocation and
                                             immediately adjacent to the
                                             description of the NGC Asset
                                             to which it relates.

          4.2  In the event that a Termination Amount specified in
               paragraph 4.1(a)(i) is paid, in respect of Type A Assets,
               and subsequently NGC re-uses such NGC Assets in respect of
               which such payment has been made at the same or another
               Connection Site then NGC shall pay to the User a sum equal
               to the lower of:

               (i)  the Termination Amount paid in respect of such NGC
                    Asset; or

               (ii) the Net Asset Value attributed to such NGC Asset for
                    charging purposes upon its re-use.

               less any reasonable costs incurred by NGC in respect of
               storage.  NGC shall use its reasonable endeavors to re-use
               such NGC Assets.

          4.3  In the event that a Termination Amount specified in
               paragraph 4.1(a)(ii) above is paid in respect of Type B
               Assets and these are subsequently re-used then NGC shall pay
               to the User a sum equal to the lower of:

               (i)  the Termination Amount paid in respect of such NGC
                    Assets; or

               (ii) the Net Asset Value attributed to such NGC Asset for
                    charging purposes upon its re-use.

          4.4  For the purposes of paragraphs 4.2 and 4.3 re-use shall not
               occur where any NGC Asset remains connected for the purpose
               of providing a continuing connection for other Users
               connected to the NGC Transmission System at the Connection
               Site at the date of termination.  However in the event of
               any User requiring a continued connection modifying its
               requirements or another User connecting at the Connection
               Site and the NGC Assets in respect of which a payment has
               been made are required for this modification this shall
               constitute re-use.

          4.5  NGC shall be under no obligation to rebate any of the
               Termination Amounts described in paragraph 4.1(b), except to
               the extent that Connection and/or Transmission Network Use
               of System Charges are subsequently received in respect of
               NGC Assets in relation to which such Termination Amounts
               have been paid to NGC during the Financial Year in which
               termination has occurred.

          4.6  Upon request in writing, and at the cost of the User, NGC
               shall issue a certificate no more recently than once each
               calendar year indicating whether or not such assets have or
               have not been re-used.  If NGC at any time decide that it is
               not economic to retain any Plant and Apparatus constituting
               any NGC Asset in respect of which Termination Amounts have
               been paid it may at its reasonable discretion dispose of the
               said Plant and Apparatus.  Where NGC decides to so dispose
               of such Plant and Apparatus it shall where the Plant and/or
               Apparatus is disposed of in a state where it is capable of
               re-use pay to the User an appropriate proportion of any sale
               proceeds received in respect thereof.

          5.   Deductions
               ----------

               In respect of any NGC Engineering Charges which have been
               paid by the User in connection with a Connection Application
               or under Sub-Clause 2.4 of the Supplemental Agreement Type 2
               NGC shall reduce the amount of Connection Charges payable by
               the User in relation to the respective Connection Site on 1
               April in each of the first 3 years (or such other period as
               may be agreed between NGC and the User) of the payment of
               such Connection Charges by an amount equal on each occasion
               to one third of such NGC Engineering Charges.

          Part 2 Transmission Services Use of System Charges
          --------------------------------------------------

          Introduction
          ------------

          Under the terms of this Supplemental Agreement the User is liable
          to pay Transmission Services Use of System Charges.  The basis
          upon which Transmission Services Use of System Charges are levied
          and the calculation methodology and rules which will be used to
          quantify those charges are set out in the statement issued by NGC
          under paragraphs 1 and 2 of Condition 10 to the Transmission
          License.

          1.   Reconciliation
               --------------

          1.1  At any time after the Payment Date NGC may submit to the
               User, and shall submit to the User at the written request of
               the User a Statement (which may form part of an invoice or
               other document) in respect of any Settlement Day (a
               "Reconciliation Statement") showing:

               (a)  each Settlement Day in respect of which there has been
                    a change (for any reason) in the value of any parameter
                    originally used in the calculation of the Transmission
                    Services Use of System Charges in respect of such
                    Settlement Day, together with details of the value of
                    the old and new parameter;

               (b)  the amount of any reconciliation payments (if any)
                    required to make the Transmission Services Use of
                    System Charges paid in respect of that Settlement Day
                    equal to the payment which would have been payable had
                    the invoice prepared pursuant to Clause 5.4.1 of this
                    Supplemental Agreement been prepared on the basis of
                    the changed parameter;

               (c)  whether the reconciliation payment represents an amount
                    owing by NGC to the User or by the User to NGC;

               (d)  the amount of interest accruing on such reconciliation
                    payment calculated in accordance with this paragraph
                    1.1 below.

               Interest payable in respect of each reconciliation payment
               shall accrue from and including the relevant Payment Date up
               to but excluding the date upon which the amounts specified
               in the Reconciliation Statement are paid, and shall be at a
               rate equal to the Base Rate for the time being and from time
               to time.  Interest shall accrue from day to day

          1.2  Together with the Reconciliation Statement in the case of
               sums due:

                         with paragraph 1.1; or

               (b)  from NGC to the User, forthwith following the issue of
                    any Reconciliation Statement, NGC shall;

                    (i)  issue a credit note in relation to any sum shown
                         by the Reconciliation Statement to be due to the

          1.3  The right to submit a Reconciliation Statement and the
               consequential invoices and/or credit notes shall survive the
               termination of this Supplemental Agreement and the parties
               agree that the provisions of this Appendix E Part 2 shall
               remain in full force and effect and shall continue to bind
               them after such termination (the version in existence as at
               the date of termination being the applicable version, in the
               case of any amendments).

                         (a)  this Supplemental Agreement shall relieve it
                              of its obligations to provide such security
                              under the terms of any other Supplemental
                              Agreement to which the User is a party; and

                         (b)  any other Supplemental Agreement to which the
                              User is a party shall relieve it of its
                              obligations to provide such security under
                              the terms of this Supplemental Agreement;

                         in each case, to the extent of the security
                         provided to NGC pursuant to this Appendix or the
                         same provision under the terms of any other
                         Supplemental Agreement made between NGC and the

               1.1.4     The provisions of this Part 3 of Appendix E shall
                         be in addition to any other requirements to

                         under the terms of this Supplemental Agreement.

          1.2  Maintenance of Security Cover
               -----------------------------

               Where the User is required to provide Security Cover in
               accordance with the terms of paragraph 1.1 it shall at all
               times thereafter maintain a Security Amount equal to or more
               than the Security Cover applicable to it.  Immediately upon
               any reduction occurring in the Security Amount provided by
               the User or any Letter of Credit or Qualifying Guarantee
               being for any reason drawn down or demanded respectively,
               the User will procure that new Letters of Credit or
               Qualifying Guarantees are issued or existing Letters of
               Credit or Qualifying Guarantees are reinstated (to the
               satisfaction of NGC) to their full value or cash is placed
               to the credit of the Escrow Account in an amount required to
               restore the Security Amount to an amount at least equal to
               the Security Cover applicable to the User, and in such
               proportions of Letters of Credit, Qualifying Guarantees
               and/or cash as the User may determine.  Not later than 10
               Business Days before any outstanding Letter of Credit and/or
               Qualifying Guarantee is due to expire, the User shall
               procure to the satisfaction of NGC that its required
               Security Amount will be available for a further period of
               not less than 6 months which may be done in one of the
               following ways:

               1.2.1     subject to the issuing bank continuing to have an
                         Approved Credit Rating provide NGC with
                         confirmation from the issuing bank that the
                         validity of the Letter of Credit has been extended
                         for a period of not less than 6 months on the same
                         terms and otherwise for such amount as is required
                         by this Part 3; or

               1.2.2     provide NGC with a new Letter of Credit issued by
                         an issuing bank with an Approved Credit Rating for
                         an amount at least equal to the required Security
                         Amount applicable to it (less its balance on the
                         Escrow Account) which Letter of Credit shall be
                         available for a period of not less than 6 months;
                         or

               1.2.3     subject to the entity issuing the Qualifying
                         Guarantee continuing to have an Approved Credit
                         Rating provide NGC with confirmation from the
                         issuing entity that the validity of the Qualifying
                         Guarantee has been extended for a period of not
                         less than 6 months on the same terms and otherwise
                         for such amount as is required by this Part 3; or

               1.2.4     provide NGC with a new Qualifying Guarantee for an
                         amount at least equal to the required Security
                         Amount applicable to it (less its balance on the
                         Escrow Account) which Qualifying Guarantee shall
                         be available for a period of not less than 6
                         months; or

               1.2.5     procure such transfer to NGC for credit to the
                         Escrow Account of an amount as shall ensure that
                         the credit balance applicable to the User and
                         standing to the credit of the Escrow Account shall
                         be at least equal to the required Security Amount.

          1.3  Failure to supply or maintain Security Cover
               --------------------------------------------

               If the User fails at any time to provide or maintain
               Security Cover to the satisfaction of NGC in accordance with
               the provisions of this Part 3, NGC may at any time while
               such default continues, and if at such time any Letter of
               Credit and/or Qualifying Guarantee forming part of the
               Security Cover is due to expire within nine Business Days
               immediately, and without notice to the User, demand payment
               of the entire amount of any outstanding Letter of Credit
               and/or Qualifying Guarantee and shall credit the proceeds of
               the Letter of Credit and/or Qualifying Guarantee to the
               Escrow Account.

          1.4  Substitute Letter of Credit or Qualifying Guarantee
               ---------------------------------------------------

          1.4.1     If the bank issuing the User's Letter of Credit ceases
                    to have the credit rating set out in the definition of
                    Letter of Credit in Clause 1.1 of this Supplemental
                    Agreement such User shall forthwith procure the issue
                    of a substitute Letter of Credit by a bank that has
                    such a credit rating or a Qualifying Guarantee or
                    transfer to NGC cash to be credited to the Escrow
                    Account.

          1.4.2     If the entity providing the User's Qualifying Guarantee
                    ceases to have an Approved Credit Rating the User shall
                    forthwith procure a replacement Qualifying Guarantee
                    from an entity with such a credit rating or a Letter of
                    Credit or transfer to NGC cash to be credited to the
                    Escrow Account.

          2    CREDIT MONITORING
               -----------------

          2.1  Determination of Security Cover
               -------------------------------

               The amount of Security Cover which the User shall be
               required to maintain shall be determined from time to time
               by NGC in accordance with this Part 3 on the basis of the
               criteria set out in paragraph 2.2 and shall be notified to
               the User.

          2.2  Criteria for provision of Security Cover
               ----------------------------------------

               If paragraph 1.1.2 applies, the amount of Security Cover
               required to be provided by the User in respect of this and
               any other Supplemental Agreement to which the User is a
               party shall be provided in an amount to be reasonably
               assessed by NGC as the aggregate amount reasonably
               anticipated by NGC as being payable by the User pursuant to
               all Supplemental Agreements to which the User is a party in
               respect of the Transmission Services Use of System Charges
               referred to in Part 2 of Appendix D over a 28 day period.

          2.3  Six Monthly Variation
               ---------------------

               In respect of paragraph 2.2 NGC shall calculate the amount
               for the two six-month periods commencing 1st April and 1st
               October in each year and shall advise the User accordingly.

          2.4  Review of Security Cover
               ------------------------

               NGC shall keep under review the Security Cover relating to
               the User and shall promptly advise the User whenever the
               Security Amount maintained by the User is more or less than
               the amount required to be maintained pursuant to paragraph 2
               of this Part 3.

          2.5  Increase or Decrease of Security Cover
               --------------------------------------

               If, after considering any representations which may be made
               by the User, NGC reasonably determines that the User's
               Security Cover should be increased or decreased, it shall so
               notify the User.  If NGC so determines that such Security
               Cover should be decreased and the User consents then that
               reduction shall take place.  NGC shall consent to an
               appropriate reduction in the available amount of any
               outstanding Qualifying Guarantee or Letter of Credit and/or
               shall repay to the User such part of the deposit held in the
               Escrow Account for the account of the User (together with
               all accrued interest on the part to be repaid) sufficient to
               reduce the User's Security Amount to the level of Security
               Cover applicable to it.  If NGC so determines that the
               User's Security Cover should be increased, the User shall,
               within five Business Days of notice as aforesaid, procure an
               additional or replacement Qualifying Guarantee or Letter of
               Credit or transfer to NGC cash to be credited to the Escrow
               Account in an amount sufficient to increase its Security
               Amount so as to be at least equal to the level of Security
               Cover applicable to it.

          2.6  Notification in respect of Security Cover
               -----------------------------------------

               NGC shall notify the User promptly if:

               2.6.1     the User fails to provide, maintain, extend or
                         renew a Qualifying Guarantee or a Letter of Credit
                         which it is required to provide, maintain, extend
                         or renew pursuant to paragraphs 1 or 2;

               2.6.2     NGC shall make a demand under any such Qualifying
                         Guarantee or a call under a Letter of Credit; or

               2.6.3     NGC becomes aware that the User (a) shall cease to
                         have an Approved Credit Rating, or (b) shall be
                         placed on credit watch by the relevant credit
                         rating agency (or becomes subject to an equivalent
                         procedure) which in any case casts doubt on the
                         User retaining an Approved Credit Rating, or (c)
                         shall be in default under the additional or
                         alternative security required to be provided
                         pursuant to this Part 3; or

               2.6.4     NGC becomes aware that any bank that has issued a
                         Letter of Credit which has not expired shall cease
                         to have the credit rating required by this
                         Appendix; or

               2.6.5     NGC becomes aware that any entity providing a
                         Qualifying Guarantee which has not expired shall
                         cease to have an Approved Credit Rating.

               Provided always that the failure by NGC to notify the User
               pursuant to this paragraph 2.6 shall not relieve the User of
               its obligations under and in accordance with the terms of
               this Appendix.

          2.7  Release from Security Cover Obligations
               ---------------------------------------

               Upon the User ceasing to be a party to the Master Agreement
               and provided that all amounts owed by the User in respect of
               the Transmission Services Use of System Charges have been
               duly and finally paid and that it is not otherwise in

                    If, following any De-Energisation pursuant to this
                    Clause 13, the User applies to NGC for NGC to issue
                    instructions that the User's Equipment should be Re-
                    energised and is refused or is offered terms which the
                    User does not accept, this shall be recognised as a
                    dispute over the terms for connection and use of system
                    which the User may refer to the Director for
                    determination under the NGC Transmission Licence.  If
                    the User accepts any terms offered by NGC or settled by
                    the Director pursuant to any such reference, NGC shall
                    request the owner of the Distribution System to which
                    the User is connected to Re-energise the User's
                    Equipment forthwith after any request from the User for
                    NGC to do so.

          13.6      Event of Default
                    ----------------

                    If the breach which led to any De-energisation pursuant
                    to this Clause 13 remains unremedied at the expiry of
                    at least 6 months after the date of such De-
                    energisation, NGC may declare by notice in writing to
                    the User that such breach has become an event of
                    default provided that-

                    (a)     all disputes arising out of the subject-matter
                            to this Clause 13 which are referred to the
                            Dispute Resolution Procedure have then been
                            finally determined in favour of NGC; and

                    (b)     any reference to the Director pursuant to sub-
                            clause 13.5 has then been finally determined
                            in favour of NGC or any terms settled by the
                            Director pursuant to such application have not
                            been accepted by the User.

          13.7      Disconnection
                    -------------

                    Once NGC has given a valid notice of an event of
                    default pursuant to Sub-Clause 13.6 NGC may give notice
                    of termination to that User whereupon this Supplemental

                    (ii)    the average Demand within the Trading Site
                            (other than Station Demand) to be supplied by
                            the Power Station in (i) above for each of the
                            number of peak half hours notified by the User
                            to NGC pursuant to paragraph 2.1; and

                    (iii)   the Station Demand for the Power Station
                            within the Trading Site determined in
                            accordance with paragraph 1.1.2(c)(i)

               for the period as notified by NGC to the User under
               paragraph 2.1 and NGC shall use such forecasts as the basis
               of Transmission Network Use of System Charges for such
               Financial Year.

          1.1.3     Variation of Charges by NGC during the Financial Year
                    -----------------------------------------------------

               The User shall notify NGC of any revision to the forecast
               Demand submitted by the User under paragraph 1.1 of this
               Appendix E at least quarterly or at such other intervals as
               may be agreed between NGC and the User from time to time.
               NGC shall revise the Transmission Network Use of System
               Charges payable by the User to take account of any such
               revised forecast provided in accordance with this paragraph
               1.1.3.  NGC shall commence charging the varied Transmission
               Network Use of System Charges from the first day of the
               month following the month in which such revised forecast was
               received provided always that such forecast is provided
               before 15th day of such month.

          1.2  Reconciliation Statements
               --------------------------

               Initial Reconciliation Statements
               ---------------------------------

          1.2.1     On or before 1 March in each Financial Year NGC shall
                    promptly calculate on the basis set out in the
                    statement published by NGC in accordance with Licence
                    Condition 10 of the Transmission Licence the Demand
                    related or Generation related Transmission Network Use
                    of System Charges (as the case may be) that would have
                    been payable by the User during each month during that
                    Financial Year if those charges had been calculated on
                    the basis of the actual Demand data or the User's
                    highest declared Registered Capacity recorded during
                    the Financial Year in respect of the forecasts which
                    had previously been provided by the User in accordance
                    with paragraph 1.1 (the "Actual Amount").  NGC shall
                    then compare the Actual Amount with the amount of
                    Demand related or Generation related Transmission
                    Network Use of System Charges (as the case may be) paid
                    during each month during that Financial Year by the
                    User (the "Notional Amount").

          1.2.2     As soon as reasonably practicable and in any event by
                    1st March in each Financial Year NGC shall then prepare
                    an initial reconciliation statement and send it to the
                    User.  Such statement shall specify the Actual Amount
                    and the Notional Amount for each month during the
                    relevant Financial Year and, in reasonable detail, the
                    information from which such amounts were derived and
                    the manner in which they were calculated.

          1.2.3     Together with the initial reconciliation statement NGC
                    shall issue a credit note in relation to any sum shown
                    by the reconciliation statement to be due to the User
                    or an invoice in respect of sums due to NGC and in each
                    case interest thereon calculated pursuant to paragraph
                    1.2.5 below.

          1.2.4     Invoices issued under paragraph 1.2.3 above and 1.2.5
                    below shall be payable on or before 31 st March in the
                    Financial Year to which they relate.

          1.2.5     In respect of the Financial Year:-

               (a)  the User shall, following receipt of an appropriate
                    invoice, pay to NGC an amount equal to the amount (if
                    any) by which the aggregate Actual Amount exceeds the
                    aggregate Notional Amount; and

               (b)  NGC shall issue the User with a credit note for an
                    amount equal to the amount (if any) by which the
                    aggregate Notional Amount exceeds the aggregate Actual
                    Amount.

               Interest shall be payable by the paying Party to the other
               on such amounts from the date of payment applicable to the
               month concerned until the date of actual payment of such
               amounts and such interest shall be calculated on a daily
               basis at a rate equal to the Base Rate during such period.

               Final Reconciliation Statements
               -------------------------------

          1.2.6     (a)     NGC shall as soon as reasonably practicable
                            after the end of each Financial Year issue a
                            further reconciliation statement in respect of
                            Transmission Network Use of System Charges
                            payable in respect of each month of that
                            Financial Year showing:-

                    (i)     any change in the Transmission Network Use of
                            System Charges from those specified in the
                            initial reconciliation statement provided in
                            accordance with paragraph 1.2.1 above;

                    (ii)    whether the change represents a reconciliation
                            payment owing by NGC to a User or by a User to
                            NGC;

                    (iii)   the amount of interest determined in
                            accordance with 1.2.5 above;

                    (iv)    the information from which the amounts in (i)
                            above are derived and the manner of their
                            calculation.

               (b)  The provisions of paragraphs 1.2.3 and 1.2.5 shall
                    apply mutatis mutandis to sums specified in the Final
                    Reconciliation Statement.


          2.   Revision of Charges
               -------------------

          2.1  To the extent permitted by the Transmission Licence and this
               Agreement NGC may revise its Connection Charges and
               Transmission Network Use of System Charges or the basis of
               their calculation including issuing revisions to Appendices
               A, B, C and D (or D1 if appropriate) hereto.  On or before
               31st October in each Financial Year NGC shall notify the
               User in writing of the intended basis of calculation to be
               used by NGC in the following Financial Year together with
               time periods over which the data required to be provided
               pursuant to paragraph 1 of this Appendix E is required and
               shall consult with the User concerning the same.  On or
               before 30th November in each Financial Year NGC shall
               confirm to the User the basis of calculation to be used in
               the following Financial Year.

          2.2  NGC shall give the User not less than 2 months, prior
               written notice of any revised charges, including revisions
               to Appendices A, B, C and D (or D1 if appropriate) hereto,
               which notice shall specify the date upon which such
               revisions become effective (which may be at any time).  The
               User shall pay any such revised charges and Appendix A, B,
               C, D (and/or D1 as appropriate) shall be amended
               automatically (and a copy sent to the User) to reflect any
               changes to such Appendices with effect from the date
               specified in such notice.

          2.3  Subject to the provisions of paragraph 3.2 below if in the
               reasonable opinion of NGC any development, replacement,
               renovation, alteration, construction or other work to the
               NGC Transmission System or termination of a Supplemental
               Agreement by another User or an alteration to the
               requirements of the User or any other User means that to
               ensure that NGC is charging in accordance with the
               provisions of the Statement pursuant to Condition 10 of the
               Transmission Licence NGC needs to vary the Connection
               Charges payable by the User in relation to the Connection
               Site then NGC shall have the right to vary such charges
               accordingly upon giving to the User not less than 2 months,
               prior written notice.  Such notice shall be deemed to be a
               revised Connection Offer and before any such variation
               becomes effective the provisions of Sub-Clauses 11.3 to 11.4
               of the Master Agreement shall apply mutatis mutandis.
               Following any such variation the provisions of Appendices A
               and B shall be amended automatically (and a copy sent to the
               User) to reflect such variation with effect from the date
               such variation comes into effect.


          3.   Replacement of NGC Assets
               -------------------------

          3.1  Appendix A specified the age of each of the NGC Assets at
               the Connection Site at the date of this Supplemental
               Agreement.  NGC Connection Charges are calculated on the
               assumption that NGC Assets will not require replacement
               until the expiry of the Replacement Period applicable to
               each NGC Asset concerned and such period has been agreed
               between NGC and the User.

          3.2  Where in NGC's reasonable opinion an NGC Asset requires
               replacement before the expiry of its Replacement Period NGC
               shall, with the prior written approval of the User (except
               where in NGC's reasonable opinion such replacement is
               necessary in which case such approval shall not be required
               but in such case the User shall have the right to
               Disconnect) have the right to replace the NGC Asset at no
               additional cost to the User until expiry of its original
               Replacement Period.  Upon expiry of such original
               Replacement Period NGC shall be entitled to vary the
               Connection Charges in respect of the replaced NGC Asset so
               that they are calculated on the basis of the then Net Asset
               Value of such NGC Assets.  NGC shall give the User not less
               than 2 months, prior written notice of such varied charges
               which notice shall specify the date upon which such increase
               or reduction (as the case may be) becomes effective.  The
               User shall pay such varied charges and Appendices A and B
               shall be amended automatically (and a copy sent to the User)
               to reflect such revised charges with effect from the date
               specified in such notice.

          3.3  Upon the expiry of the Replacement Period of any NGC Asset:-

               (a)  (i)     if in NGC's reasonable opinion to enable NGC
                            to comply with its licence and statutory
                            obligations it is necessary to replace such
                            NGC Asset; or

                    (ii)    if such NGC Asset is to be left in service,

                            then NGC shall give written notice of this and
                            that it will, unless within 3 months of the
                            receipt of such notice the User objects in
                            writing to the proposal, replace or retain (as
                            the case may be) such NGC Asset.

               (b)  the User may request that NGC replaces the Asset.

          3.4  Where the User serves a counter notice pursuant to paragraph
               3.3 above then NGC sh.

               (a)  keep the NGC Asset in service; and

               (b)  negotiate with the User in good faith with regard to
                    the Connection Charges applicable to such NGC Asset.

               In the event that NGC and the User fail to agree the level
               of such Connection Charges in accordance with paragraph
               3.4(b) above then the User shall pay Connection Charges to
               NGC in respect of such NGC Asset equal to the Connection
               Charges payable by the User in respect of the NGC Asset in
               the last Financial Year of the Replacement Period (the
               "Deemed Charge") and the matter shall be referred to the
               Director for determination.  If the Director determines that
               the Connection Charges payable in respect of such NGC Asset
               should be:-

               (i)  less than the Deemed Charge then NGC shall repay to the
                    User the difference between the Deemed Charge and the
                    amount so determined by the Director together with
                    interest at the Base Rate, for the period from when the
                    User started to pay the Deemed Charge until the date of
                    payment;

               (ii) greater than the Deemed Charge then the User shall pay
                    the difference to NGC together with interest at the
                    Base Rate for the period from when the User started to
                    pay the Deemed Charge until the date of payment.

          3.5  Where the Connection Charges are payable in respect of NGC
               Assets:-

               (a)  replaced in accordance with paragraph 3.3 above; or

               (b)  retained in accordance with paragraph 3.3 above

               then NGC shall except in the circumstances in paragraph
               3.4(b) give the User not less than 2 months, prior written
               notice of such varied charges and specify the date upon
               which such charges become effective.  The User shall pay
               such varied charges and Appendices A and B shall be amended
               automatically (and a copy sent to the User) to reflect such
               revised charges with effect from the dates notified to the
               User by NGC.

               Where NGC is in negotiation with the User in accordance with
               paragraph 3.4(b) then it shall give notice as is reasonably
               practicable in the circumstances.


          4.   Termination Amounts
               -------------------

          4.1  The expressions set out below shall have the meanings
               shown:-

               "Termination Amount"     shall be the sum calculated to be
                                        equal to the aggregate of the
                                        following:-

                                   (a)  in respect of NGC Assets:-

                                             Supplemental Agreement and
                                             which, in NGC's reasonable
                                             opinion, are no longer
                                             required by NGC to enable NGC
                                             to comply with its Licence
                                             Standards, and can therefore
                                             be removed ("Type A Assets"),
                                             (aa) the Net Asset Value of
                                             such NGC Asset as at the end
                                             of the Financial Year in which
                                             termination occurs (on the
                                             assumption that the sums
                                             specified in paragraph 4.1(b)
                                             will be paid), plus (bb) a sum
                                             equal to the reasonable costs
                                             of removing such NGC Assets
                                             and of making good the
                                             remaining Plant and Apparatus
                                             at the Connection Site
                                             following the removal of any
                                             Type A Assets;

                                             ("Type B Assets") as a result
                                             of the termination, a sum
                                             equal to the product of the
                                             Asset Allocation Factor
                                             multiplied by the Net Asset
                                             Value of that NGC Asset as at
                                             the end of the Financial Year
                                             in which termination occurs;
                                             and

                                                  such NGC Assets by the
                                                  User by the date of
                                                  termination,

                                             the reasonable costs incurred
                                             by NGC in connection with the
                                             installation of such NGC
                                             Assets;

                                   (b)  the Connection Charges and Use of
                                        System Charges for the Financial

               "Asset Allocation Factor"     means in respect of each NGC
                                             Asset specified in Appendix A
                                             to this Supplemental Agreement
                                             the figure expressed as a
                                             percentage appearing in the
                                             column headed Allocation and
                                             immediately adjacent to the
                                             description of the NGC Asset
                                             to which it relates.

          4.2  In the event that a Termination Amount specified in
               paragraph 4.1(a)(i) is paid, in respect of Type A Assets,
               and subsequently NGC re-uses such NGC Assets in respect of
               which such payment has been made at the same or another
               Connection Site then NGC shall pay to the User a sum equal
               to the lower of:

               (i)  the Termination Amount paid in respect of such NGC
                    Asset; or

               (ii) the Net Asset Value attributed to such NGC Asset for
                    charging purposes upon its
                    re-use,

               less any reasonable costs incurred by NGC in respect of
               storage.  NGC shall use its reasonable endeavours to re-use
               such NGC Assets.

          4.3  In the event that a Termination Amount specified in
               paragraph 4.1(a)(ii) above is paid in respect of Type B
               Assets and these are subsequently re-used then NGC shall pay
               to the User a sum equal to the lower of:-

               (i)  the Termination Amount paid in respect of such NGC
                    Assets; or

               (ii) the Net Asset Value attributed to such NGC Asset for
                    charging purposes upon its
                    re-use.

          4.4  For the purposes of paragraphs 4.2 and 4.3 re-use shall not
               occur where any NGC Asset remains connected for the purpose
               of providing a continuing connection for other Users
               connected to the NGC Transmission System at the Connection
               Site at the date of termination.  However in the event of
               any User requiring a continued connection modifying its
               requirements or another User connecting at the Connection
               Site and the NGC Assets in respect of which a payment has
               been made are required for this modification this shall
               constitute re-use.

          4.5  NGC shall be under no obligation to rebate any of the
               Termination Amounts described in paragraph 4.1(b) except to
               the extent that Connection and/or Transmission Network Use
               of System Charges are subsequently received in respect of
               NGC Assets in relation to which such Termination Amounts
               have been paid to NGC during the Financial Year in which
               termination has occurred.

          4.6  Upon request in writing, and at the cost of the User, NGC
               shall issue a certificate no more frequently than once each
               calendar year indicating whether or not such assets have or
               have not been re-used.  If NGC at any time decide that it is
               not economic to retain any Plant and Apparatus constituting
               any NGC Asset in respect of which Termination Amounts have
               been paid it may at its reasonable discretion dispose of the
               said Plant and Apparatus.  Where NGC decides to so dispose
               of such Plant and Apparatus it shall where the Plant and/or
               Apparatus is disposed of in a state where it is capable of
               re-use pay to the User an appropriate proportion of any sale
               proceeds received in respect thereof.


          5.   Deductions
               ----------

               In respect of any NGC Engineering Charges which have been
               paid by the User in connection with a Connection Application
               or under Sub-Clause 2.4 of the Supplemental Agreement Type 2
               NGC shall reduce the amount of Connection Charges payable by
               the User in relation to the respective Connection Site on 1
               April in each of the first 3 years (or such other period as
               may be agreed between NGC and the User) of the payment of
               such Connection Charges by an amount equal on each occasion
               to one third of such NGC Engineering Charges.



          Part 2 - Transmission Services Use of System Charges
          ----------------------------------------------------

          Introduction
          ------------

          Under the terms of this Supplemental Agreement the User is liable
          to pay Transmission Services Use of System Charges.  The basis
          upon which Transmission Services Use of System Charges are levied
          and the calculation methodology and rules which will be used to
          quantify those charges are set out in the statement issued by NGC
          under paragraphs 1 and 2 of Condition 10 to the Transmission
          Licence.

          1.   Reconciliation
               --------------

          1.1  At any time after the Payment Date NGC may submit to the
               User, and shall submit to the User at the written request of
               the User, a Statement (which may form part of an invoice or
               other document) in respect of any Settlement Day (a
               "Reconciliation Statement") showing:-

               (a)  each Settlement Day in respect of which there has been
                    a change (for any reason) in the value of any parameter
                    originally used in the calculation of the Transmission
                    Services Use of System Charges in respect of such
                    Settlement Day, together with details of the value of
                    the old and new parameter;

               (b)  the amount of any reconciliation payments (if any)
                    required to make the Transmission Services Use of
                    System Charges paid in respect of that Settlement Day
                    equal to the payment which would have been payable had
                    the invoice prepared pursuant to Clause 5.4.1 of this
                    Supplemental Agreement been prepared on the basis of
                    the changed parameter;

               (c)  whether the reconciliation payment represents an amount
                    owing by NGC to the User or by the User to NGC;

               (d)  the amount of interest accruing on such reconciliation
                    payment calculated in accordance with this paragraph
                    1.1 below.

               Interest payable in respect of each reconciliation payment
               shall accrue from and including the relevant Payment Date up
               to but excluding the date upon which the amounts specified
               in the Reconciliation Statement are paid, and shall be at a
               rate equal to the Base Rate for the time being and from time
               to time.  Interest shall accrue from day to day.

          1.2  Together with the Reconciliation Statement in the case of
          sums due:-

               (a)  from the User to NGC, NGC shall:-

                    (i)     send the User an invoice in relation to any
                            sums shown by the Reconciliation Statement to
                            be due to NGC and interest thereon calculated
                            in accordance with paragraph 1.1; or

                    (ii)    include those sums due in another invoice; and

               (b)  from NGC to the User, forthwith following the issue of
                    any Reconciliation Statement, NGC shall:-

                    (i)     issue a credit note in relation to any sum
                            shown by the Reconciliation Statement to be
                            due to the User and interest thereon
                            calculated in accordance with paragraph 1.1;
                            or

                    (ii)    include those sums due to the User as a credit
                            in an invoice from NGC to the User.

          1.3  The right to submit a Reconciliation Statement and the
               consequential invoices and/or credit notes shall survive the
               termination of this Supplemental Agreement and the parties
               agree that the provisions of this Appendix E Part 2 shall
               remain in full force and effect and shall continue to bind
               them after such termination (the version in existence as at
               the date of termination being the applicable version, in the
               case of any amendments).


          2.   Reconciliation Payments
               -----------------------

               The User, or as the case may be, NGC, shall pay the amounts
               set out in the relevant invoice or credit note, either in
               accordance with the applicable requirements for payment of
               other sums due under that invoice in the case of sums shown
               in an invoice also dealing with other payments, or in other
               cases within 5 Business Days of the date of the
               Reconciliation Statement.


          3.   Revision of Charges

                                   Escrow Account in such amount as shall
                                   be notified by NGC in accordance with
                                   paragraph 2;

               1.1.3        the provision of security in respect of
                            Transmission Services Use of System Charges by
                            the User in accordance with the terms of:

                            (a)    this Supplemental Agreement shall
                                   relieve it of its obligations to provide
                                   such security under the terms of any
                                   other Supplemental Agreement to which
                                   the User is a party; and

                            (b)    any other Supplemental Agreement to
                                   which the User is a party shall relieve
                                   it of its obligations to provide such
                                   security under the terms of this
                                   Supplemental Agreement,

                    in each case, to the extent of the security provided to
                    NGC pursuant to this Appendix or the same provision
                    under the terms of any other Supplemental Agreement
                    made between NGC and the User;

          1.1.4     the provisions of this Part 3 of Appendix E shall be in
                    addition to any other requirements to provide security
                    in respect of any other sums due under the terms of
                    this Supplemental Agreement.

          1.2  Maintenance of Security Cover
               -----------------------------

               Where the User is required to provide Security Cover in
               accordance with the terms of paragraph 1.1 it shall at all
               times thereafter maintain a Security Amount equal to or more
               than the Security Cover applicable to it.  Immediately upon
               any reduction occurring in the Security Amount provided by
               the User or any Letter of Credit or Qualifying Guarantee
               being for any reason drawn down or demanded respectively,
               the User will procure that new Letters of Credit or
               Qualifying Guarantees are issued or existing Letters of
               Credit or Qualifying Guarantees are reinstated (to the
               satisfaction of NGC) to their full value or cash is placed
               to the credit of the Escrow Account in an amount required to
               restore the Security Amount to an amount at least equal to
               the Security Cover applicable to the User, and in such
               proportions of Letters of Credit, Qualifying Guarantees
               and/or cash as the User may determine.  Not later than 10
               Business Days before any outstanding Letter of Credit and/or
               Qualifying Guarantee is due to expire, the User shall
               procure to the satisfaction of NGC that its required
               Security Amount will be available for a further period of
               not less than 6 months which may be done in one of the
               following ways -

               1.2.1        subject to the issuing bank continuing to have
                            an Approved Credit Rating provide NGC with
                            confirmation from the issuing bank that the
                            validity of the Letter of Credit has been
                            extended for a period of not less than 6
                            months on the same terms and otherwise for
                            such amount as is required by this Part 3; or

               1.2.2        provide NGC with a new Letter of Credit issued
                            by an issuing bank with an Approved Credit
                            Rating for an amount at least equal to the
                            required Security Amount applicable to it
                            (less its balance on the Escrow Account) which
                            Letter of Credit shall be available for a
                            period of not less than 6 months; or

               1.2.3        subject to the entity issuing the Qualifying
                            Guarantee continuing to have an Approved
                            Credit Rating provide NGC with confirmation
                            from the issuing entity that the validity of
                            the Qualifying Guarantee has been extended for
                            a period of not less than 6 months on the same
                            terms and otherwise for such amount as is
                            required by this Part 3; or

               1.2.4        provide NGC with a new Qualifying Guarantee
                            for an amount at least equal to the required
                            Security Amount applicable to it (less its
                            balance on the Escrow Account) which
                            Qualifying Guarantee shall be available for a
                            period of not less than 6 months; or

               1.2.5        procure such transfer to NGC for credit to the
                            Escrow Account of an amount as shall ensure
                            that the credit balance applicable to the User
                            and standing to the credit of the Escrow
                            Account shall be at least equal to the
                            required Security Amount.

          1.3  Failure to supply or maintain Security Cover
               --------------------------------------------

               If the User fails at any time to provide or maintain
               Security Cover to the satisfaction of NGC in accordance with
               the provisions of this Part 3, NGC may at any time while
               such default continues, and if at such time any Letter of
               Credit and/or Qualifying Guarantee forming part of the
               Security Cover is due to expire within nine Business Days
               immediately, and without notice to the User, demand payment
               of the entire amount of any outstanding Letter of Credit
               and/or Qualifying Guarantee and shall credit the proceeds of
               the Letter of Credit and/or Qualifying Guarantee to the
               Escrow Account.

          1.4  Substitute Letter of Credit or Qualifying Guarantee
               ---------------------------------------------------

               1.4.1        If the bank issuing the User's Letter of
                            Credit ceases to have the credit rating set
                            out in the definition of Letter of Credit in
                            Clause 1.1 of this Supplemental Agreement such
                            User shall forthwith procure the issue of a
                            substitute Letter of Credit by a bank that has
                            such a credit rating or a Qualifying Guarantee
                            or transfer to NGC cash to be credited to the
                            Escrow Account.

               1.4.2        If the entity providing the User's Qualifying
                            Guarantee ceases to have an Approved Credit
                            Rating the User shall forthwith procure a
                            replacement Qualifying Guarantee from an
                            entity with such a credit rating or a Letter
                            of Credit or transfer to NGC cash to be
                            credited to the Escrow Account.

          2.   Credit Monitoring
               -----------------

          2.1  Determination of Security Cover
               -------------------------------

               The amount of Security Cover which the User shall be
               required to maintain shall be determined from time to time
               by NGC in accordance with this Part 3 on the basis of the
               criteria set out in paragraph 2.2 and shall be notified to
               the User.

          2.2  Criteria for provision of Security Cover
               ----------------------------------------

               If paragraph 1.1.2 applies, the amount of Security Cover
               required to be provided by the User in respect of this and
               any other Supplemental Agreement to which the User is a
               party shall be provided in an amount to be reasonably
               assessed by NGC as the aggregate amount reasonably
               anticipated by NGC as being payable by the User pursuant to
               all Supplemental Agreements to which the User is a party in
               respect of the Transmission Services Use of System Charges
               referred to in Part 2 of Appendix D over a 28 day period.

          2.3  Six Monthly Variation
               ---------------------

               In respect of paragraph 2.2 NGC shall calculate the amount
               for the two six-month periods commencing 1st April and 1st
               October in each year and shall advise the User accordingly.

          2.4  Review of Security Cover
               ------------------------

               NGC shall keep under review the Security Cover relating to
               the User and shall promptly advise the User whenever the
               Security Amount maintained by the User is more or less than
               the amount required to be maintained pursuant to paragraph 2
               of this Part 3.

          2.5  Increase or Decrease of Security Cover
               --------------------------------------

               If, after considering any representations which may be made
               by the User, NGC reasonably determines that the User's
               Security Cover should be increased or decreased, it shall so
               notify the User.  If NGC so determines that such Security
               Cover should be decreased and the User consents then that
               reduction shall take place.  NGC shall consent to an
               appropriate reduction in the available amount of any
               outstanding Qualifying Guarantee or Letter of Credit and/or
               shall repay to the User such part of the deposit held in the
               Escrow Account for the account of the User (together with
               all accrued interest on the part to be repaid) sufficient to
               reduce the User's Security Amount to the level of Security
               Cover applicable to it.  If NGC so determines that the
               User's Security Cover should be increased, the User shall,
               within five Business Days of notice as aforesaid, procure an
               additional or replacement Qualifying Guarantee or Letter of
               Credit or transfer to NGC cash to be credited to the Escrow
               Account in an amount sufficient to increase its Security
               Amount so as to be at least equal to the level of Security
               Cover applicable to it.



          2.6  Notification in Respect of Security Cover
               -----------------------------------------

               NGC shall notify the User promptly if:

               2.6.1        the User fails to provide, maintain, extend or
                            renew a Qualifying Guarantee or a Letter of
                            Credit which it is required to provide,
                            maintain, extend or renew pursuant to
                            paragraphs 1 or 2;

               2.6.2        NGC shall make a demand under any such
                            Qualifying Guarantee or a call under a Letter
                            of Credit; or

               2.6.3        NGC becomes aware that the User (a) shall
                            cease to have an Approved Credit Rating, or
                            (b) shall be placed on credit watch by the
                            relevant credit rating agency (or becomes
                            subject to an equivalent procedure) which in
                            any case casts doubt on the User retaining an
                            Approved Credit Rating, or (c) shall be in
                            default under the additional or alternative
                            security required to be provided pursuant to
                            this Part 3; or

               2.6.4        NGC becomes aware that any bank that has
                            issued a Letter of Credit which has not
                            expired shall cease to have the credit rating
                            required by this Appendix; or

               2.6.5        NGC becomes aware that any entity providing a
                            Qualifying Guarantee which has not expired
                            shall cease to have an Approved Credit Rating.

               Provided always that the failure by NGC to notify the User
               pursuant to this paragraph 2.6 shall not relieve the User of
               its obligations under and in accordance with the terms of
               this Appendix.

          2.7  Release from Security Cover Obligations
               ---------------------------------------

               Upon the User ceasing to be a party to the Master Agreement
               and provided that all amounts owed by the User in respect of
               the Transmission Services Use of System Charges have been
               duly and finally paid and that it is not otherwise in
               default in any respect of any Transmission Services Use of
               System Charges (including interest) payable under the terms
               of any Supplemental Agreement, the User shall be released
               from the obligation to maintain Security Cover and NGC shall
               consent to the revocation of any outstanding Qualifying
               Guarantee or Letter of Credit and shall repay to the User
               the balance (including interest credited thereto) standing
               to the credit of the User on the Escrow Account at that
               date.


          3.   Payment Default
               ---------------

               If by 1230 hours on any Payment Date, NGC has been notified
               by the User or it otherwise has reason to believe that the
               User will not have remitted to it by close of banking
               business on the Payment Date all or any part ("the amount in
               default") of any amount which has been notified by NGC to
               the User as being payable by the User by way of the
               Transmission Services Use of System Charges on the relevant
               Payment Date, then NGC shall be entitled to act in
               accordance with the following provisions (or whichever of
               them shall apply) in the order in which they appear until
               NGC is satisfied that the User has discharged its
               obligations in respect of the Transmission Services Use of
               System Charges under this Supplemental Agreement and/or any
               other Supplemental Agreement to which the User is a party
               which are payable in respect of the relevant Settlement Day.

               (a)  NGC may to the extent that the User is entitled to
                    receive payment from NGC pursuant to this Supplemental
                    Agreement and/or any other Supplemental Agreement to
                    which the User is a party (unless it reasonably
                    believes that such set-off shall be unlawful) set off
                    the amount of such entitlement against the amount in
                    default;

               (b)  NGC shall be entitled to set off the amount of funds
                    then standing to the credit of the Escrow Account to
                    the extent that it represents Security Cover provided
                    by the User in accordance with paragraph 2.1.2 against
                    the Transmission Services Use of System Charges unpaid
                    by the User and for that purpose NGC shall be entitled
                    to transfer any such amount from the Escrow Account to
                    any other account of NGC at its absolute discretion and
                    shall notify the User accordingly;

               (c)  NGC may demand payment under any outstanding Letter of
                    Credit supplied by the User in a sum not exceeding the
                    available amount of all such Lenders of Credit;

               (d)  NGC may demand payment under any outstanding Qualifying
                    Guarantee provided for the benefit of the User pursuant
                    to paragraph 1.1.2(a).


          4.   Utilisation of Funds
               --------------------

               In addition to the provisions of paragraph 3 above if NGC
               serves a notice of default under the terms of Clause 17.6A
               of a Type 1 Supplemental Agreement and/or notice of
               termination under Clause 17.7 of a Type 1 Supplemental
               Agreement (or the equivalent Clauses in a Supplemental
               Agreement other than a Type 1 Supplemental Agreement) then
               NGC shall be entitled to demand payment of any of the
               Transmission Services Use of System Charges which are
               outstanding whether or not the Payment Date in respect of
               them shall have passed and:

               (i)  make demand under any outstanding Qualifying Guarantee
                    or a call under any outstanding Letter of Credit
                    supplied by the User; and

               (ii) to set off the funds in the Escrow Account to the

               terms of the Master Agreement and shall be read as being
               governed by them.

          NOW IT IS HEREBY AGREED AS FOLLOWS:

          1.   DEFINITIONS, INTERPRETATION AND CONSTRUCTION
               --------------------------------------------

          1.1  GENERAL
               -------

               Unless the subject matter or context otherwise requires or
               is inconsistent therewith terms and expressions defined in
               Schedule 2 to the Master Agreement have the same meanings
               interpretations or constructions in this Supplemental
               Agreement.

          2.   RIGHT TO USE THE NGC TRANSMISSION SYSTEM

               with such margin as NGC shall in its reasonable opinion
               consider necessary having due regard to NGC's duties under
               its Transmission License except to the extent (if any) that
               NGC is prevented from doing so by transmission constraints
               or by insufficiency of generation which, in either case,
               could not have been avoided by the exercise of Good Industry
               Practice by NGC.

                    nature of the breach and requiring the User within 28
                    days after receipt of such notice to remedy the breach
                    or within any longer period agreed between NGC and the
                    User, the agreement of NGC not to be unreasonably
                    withheld or delayed; or

               (ii) where the breach is incapable of remedy, give written
                    notice to the User specifying in reasonable detail the
                    nature of the breach and the reasons why the breach is
                    incapable of remedy and requiring the User within 5
                    Business Days after receipt of such notice to undertake
                    to NGC not to repeat the breach.

          8.2  De-Energisation
               ---------------
               If:

               (a)  the User fails to comply with the terms of any valid
                    notice served on it by NGC in accordance with Sub-
                    Clause 8.1(i) or is in breach of any undertaking given
                    in accordance with Sub-Clause 8.1(ii) and such breach
                    causes or can be reasonably expected to cause a
                    material adverse effect on the business or condition of
                    NGC or other Users or the NGC Transmission System or
                    Users Systems; or

               (b)  five Business Days have elapsed since the date of any
                    valid notice served on the User in accordance with Sub-
                    Clause 8.2(ii) and no undertaking is given by the User
                    in accordance with Sub-Clause 9.2(ii);

               NGC may request the owner of the Distribution System to
               which the User's Customers are connected to De-Energise such
               Users customers upon the expiry of at least 48 hours prior
               written notice to the User provided that at the time of
               expiry of such notice the breach concerned remains
               unremedied and that neither the User nor NGC has referred
               the matter to the Dispute Resolution Procedure.  In such
               event NGC may request the owner of the Distribution System
               to which the User's Customers are connected to De-Energise
               such User's Customers forthwith following completion of the
               Dispute Resolution Procedure and final determination of the
               dispute in NGC's favour.

          8.3  NGC Transmission License
               ------------------------

               If a breach of the nature referred to in Sub-Clause 8.1
               continues to the extent that it places or seriously
               threatens to place in the immediate future NGC in breach of
               the NGC Transmission License, NGC may request the owner of
               the Distribution System to which the User's Customers are
               connected to De-Energise such User's Customers upon the
               expiry of at least 12 hours prior written notice to the
               User, provided that at the time of expiry of such notice the
               breach concerned remains unremedied.

          8.4  Re-Energisation Disputes
               ------------------------

               If, following any De-Energisation pursuant to this Clause 8,
               a User applies to NGC for NGC to issue instructions that the
               User's Customers be Re-Energised and is refused or is
               offered terms which the User does not accept, this shall be
               recognized as a dispute over the terms for use of system
               which the User may refer to the Director for determination
               under the NGC Transmission License.  If the User accepts any
               terms offered by NGC or settled by the Director pursuant to
               any such reference, NGC shall request the owner of the
               Distribution System to which the User's Customers are
               connected to Re-Energise the User's Customers forthwith
               after any request from the User for NGC to do so.

          8.5  Event of Default
               ----------------

               If the breach which led to any De-Energisation pursuant to
               this Clause 8 remains unremedied at the expiry of at least 6
               months after the date of such De-Energisation, NGC may
               declare by notice in writing to the User that such breach
               has become an event of default provided that:

               (a)  all disputes arising out of the subject-matter to this
                    Clause 8 which are referred to the Dispute Resolution
                    Procedure have then been finally determined in favour
                    of NGC; and

               (b)  any reference to the Director pursuant to Sub-Clause
                    8.4 has then been finally determined in favour of NGC
                    or any terms settled by the Director pursuant to such
                    application have not been accepted by the User.

          8.6  Disconnection
               -------------

               Once NGC has given a valid notice of an event of default
               pursuant to Sub-Clause 8.5 NGC may give notice of
               termination to that User whereupon this Supplemental
               Agreement shall terminate and:

               (i)  NGC shall request the owner of the Distribution System
                    to which that User's Customers are connected to
                    disconnect such Customers; and

               (ii) the User shall be obliged to pay to NGC forthwith the
                    Use of System Charges due hereunder up to the end of
                    the Financial Year in which Termination occurs.

          9.   NOTICE TO TERMINATE
               -------------------

          9.1  The User may terminate the Supplemental Agreement upon
               giving to NGC not less than 28 days written notice of
               termination.

          9.2  If notice to terminate is given by the User under Sub-Clause
               9.1 this Supplemental Agreement shall terminate upon the
               expiry of the notice period.  Immediately prior thereto the
               User shall pay NGC all Use of System Charges payable by the
               User under this Supplemental Agreement in respect of the
               Financial Year in which termination takes place.
               This provision shall survive the termination of this
               Supplemental Agreement.

          10.  MASTER AGREEMENT
               ----------------

               The provisions of Clauses 18 to 24 and 26 to 30 inclusive of
               the Master Agreement shall apply to this Supplemental
               Agreement as if set out in full herein.

          11.  VARIATIONS
               ----------

               No variation to this Supplemental Agreement shall be
               effective unless made in writing and signed by or on behalf
               of both NGC and the User.  NGC and the User shall effect any
               amendment required to be made to this Supplemental Agreement
               by the Director as a result of a change in the Transmission
               License or an order made pursuant to the Act or as a result
               of settling any of the terms hereof and the User hereby
               authorises and instructs NGC to make any such amendment on
               its behalf and undertakes not to withdraw, qualify or revoke
               such authority or instruction at any time.

                              the following Financial Year of:

                              (i)  the highest Registered Capacity declared
                                   pursuant to the terms of the Pooling and
                                   Settlement Agreement of each Generating

                         for the period as notified by NGC to the User
                         under paragraph 2.1 and NGC shall use such
                         forecasts as the basis of Transmission Network Use
                         of System Charges for such Financial Year.

               1.1.3     Variation of Charges by NGC during the Financial
                         ------------------------------------------------
                         Year
                         ----

                         The User shall notify NGC of any revision to the
                         forecast Demand submitted by the User under
                         paragraph 1.1 of this Appendix E at least
                         quarterly or at such other intervals as may be
                         agreed between NGC and the User from time to time.
                         NGC shall revise the Transmission Network Use of
                         System Charges payable by the User to take account
                         of any such revised forecast provided in
                         accordance with this paragraph 1.1.3.  NGC shall
                         commence charging the varied Transmission Network
                         Use of System Charges from the first day of the
                         month following the month in which such revised
                         forecast was received provided always that such
                         forecast is provided before 15th day of such
                         month.

          1.2  Reconciliation Statements
               -------------------------

               Initial Reconciliation Statements
               ---------------------------------

               1.2.1     On or before 1 March in each Financial Year NGC
                         shall promptly calculate on the basis set out in
                         the statement published by NGC in accordance with
                         License Condition 10 of the Transmission License
                         the Demand related or Generation related
                         Transmission Network Use of System Charges (as the
                         case may be) that would have been payable by the
                         User during each month during that Financial Year
                         if those charges had been calculated on the basis
                         of the actual Demand data or the User's highest
                         declared Registered Capacity recorded during the
                         Financial Year in respect of the forecasts which
                         had previously been provided by the User in
                         accordance with paragraph 1.1 (the "Actual
                         Amount").  NGC shall then compare the Actual
                         Amount with the amount of Demand related or
                         Generation related Transmission Network Use of
                         System Charges (as the case may be) paid during
                         each month during that Financial Year by the User
                         (the "Notional Amount").

               1.2.2     As soon as reasonably practicable and in any event
                         by 1st March in each Financial Year NGC shall then
                         prepare an initial reconciliation statement and
                         send it to the User.  Such statement shall specify
                         the Actual Amount and the Notional Amount for each
                         month during the relevant Financial Year and in
                         reasonable detail, the information from which such
                         amounts were derived and the manner in which they
                         were calculated.

               1.2.3     Together with the initial reconciliation statement
                         NGC shall issue a credit note in relation to any
                         sum shown by the reconciliation statement to be
                         due to the User or an invoice in respect of sums
                         due to NGC and in each case interest thereon
                         calculated pursuant to paragraph 1.2.5 below.

               1.2.4     Invoices issued under paragraph 1.2.3 above and
                         1.2.5 below shall be payable on or before 31st
                         March in the Financial Year to which they relate.

               1.2.5     In respect of the Financial Year:

                         (a)  the User shall, following receipt of an
                              appropriate invoice, pay to NGC an amount
                              equal to the amount (if any) by which the
                              aggregate Actual Amount exceeds the aggregate
                              Notional Amount; and

                         (b)  NGC shall issue the User with a credit note
                              for an amount equal to the amount (if any) by
                              which the aggregate Notional Amount exceeds
                              the aggregate Actual Amount.

                         Interest shall be payable by the paying Party to
                         the other on such amounts from the date or payment
                         applicable to the month concerned until the date
                         of actual payment of such amounts and such
                         interest shall be calculated on a daily basis at a
                         rate equal to the Base Rate during such period.


               Final Reconciliation Statements
               -------------------------------

               1.2.6     (a)  NGC shall as soon as reasonably practicable
                              after the end of each Financial Year issue a
                              further reconciliation statement in respect
                              of Transmission Network Use of System Charges
                              payable in respect of each month of that
                              Financial Year showing:

                              (i)  any change in the Transmission Network
                                   Use of System Charges from those
                                   specified in the initial reconciliation
                                   statement provided in accordance with
                                   paragraph 1.2.1 above;

                              (ii) whether the change represents a
                                   reconciliation payment owing by NGC to a
                                   User or by a User to NGC;

                             (iii) the amount of interest determined in
                                   accordance with 1.1.5 above;

                              (iv) the information from which the amounts
                                   in (i) above are derived and the manner
                                   of their calculation.

                         (b)  The provisions of paragraphs 1.2.3 and 1.2.5
                              shall apply mutatis mutandis to sums
                              specified in the Final Reconciliation
                              Statement.

          2.   Revision of Charges
               -------------------

          2.1  To the extent permitted by the Transmission License and this
               Agreement NGC may revise its Connection Charges and
               Transmission Network Use of System Charges or the basis of
               their calculation including issuing revisions to Appendices
               A, B, C and D (or D1 if appropriate) hereto.  On or before
               31st October in each Financial Year NGC shall notify the
               User in writing of the intended basis of calculation to be
               used by NGC in the following Financial Year together with
               time periods over which the data required to be provided
               pursuant to paragraph 1 of this Appendix E is required and
               shall consult with the User concerning the same.  On or
               before 30th November in each Financial Year NGC shall
               confirm to the User the basis of calculation to be used in
               the following Financial Year.

          2.2  NGC shall give the User not less than 2 months prior written
               notice of any revised charges, including revisions to
               Appendices A, B, C and D (or D1 if appropriate) hereto,
               which notice shall specify the date upon which such
               revisions become effective (which may be at any time).  The
               User shall pay any such revised charges and Appendix A, B,
               C, D (and/or D1 as appropriate) shall be amended
               automatically (and a copy sent to the User) to reflect any
               changes to such Appendices with effect from the date
               specified in such notice.

          2.3  Subject to the provisions of paragraph 3.2 below if in the
               reasonable opinion of NGC any development, replacement,
               renovation, alteration, construction or other work to the
               NGC Transmission System or termination of a Supplemental
               Agreement by another User or an alteration to the
               requirements of the User or any other User means that to
               ensure that NGC is charging in accordance with the
               provisions of the Statement pursuant to Condition 10 of the
               Transmission License NGC needs to vary the Connection
               Charges payable by the User in relation to the Connection
               Site then NGC shall have the right to vary such charges
               accordingly upon giving to the User not less than 2 month
               prior written notice.  Such notice shall be deemed to be a
               revised Connection Offer and before any such variation
               becomes effective the provisions of Sub-Clauses 11.3 to 11.4
               of the Master Agreement shall apply mutatis mutandis.
               Following any such variation the provisions of Appendices A
               and B shall be amended automatically (and a copy sent to the
               User) to reflect such variation with effect from the date
               such variation comes into effect.

          3.   Replacement of NGC Assets
               -------------------------

          3.1  Appendix A specifies the age of each of the NGC Assets at
               the Connection Site at the date of this Supplemental
               Agreement.  NGC Connection Charges are calculated on the
               assumption that NGC Assets will not require replacement
               until the expiry of the Replacement Period applicable to
               each NGC Asset concerned and such period has been agreed
               between NGC and the User.

          3.2  Where in NGC's reasonable opinion an NGC Asset requires
               replacement before the expiry of its Replacement Period NGC
               shall, with the prior written approval of the User (except
               where NGC's reasonable opinion such replacement is necessary
               in which case such approval shall not be required but in
               such case the User shall have the right to Disconnect) have
               the right to replace the NGC Asset at no additional cost to
               the User until expiry of its original Replacement Period.
               Upon expiry of such original Replacement Period NGC shall be
               entitled to vary the Connection Charges in respect of the
               replaced NGC Asset so that they are calculated on the basis
               of the then Net Asset Value of such NGC Assets.  NGC shall
               give the User not less than 2 months prior written notice of
               such varied charges which notice shall specify the date upon
               which such increase or reduction (as the case may be)
               becomes effective.  The User shall pay such varied charges
               and Appendices A and B shall be amended automatically (and a
               copy sent to the User) to reflect such revised charges with
               effect from the date specified in such notice.

          3.3  Upon the expiry of the Replacement Period of any NGC Asset:

               (a)  (i)  if in NGC's reasonable opinion to enable NGC to
                         comply with its license and statutory obligations
                         it is necessary to replace such NGC Asset; or

                    (ii) if such NGC Asset is to be left in service

                         then NGC shall give written notice of this and
                         that it will, unless within 3 months of the
                         receipt of such notice the User objects in writing
                         to the proposal, replace or retain 4 (as the case
                         may be) such NGC Asset,

               (b)  the User may request that NGC replaces the Asset.

          3.4  Where the User serves a counter notice pursuant to paragraph
               3.3 above then NGC shall:

               (a)  keep the NGC Asset in service; and

               (b)  negotiate with the User in good faith with regard to
                    the Connection Charges applicable to such NGC Asset.

                    In the event that NGC and the User fail to agree the
                    level of such Connection Charges in accordance with
                    paragraph 3.4(b) above then the User shall pay
                    Connection Charges to NGC in respect of such NGC Asset
                    equal to the Connection Charges payable by the User in
                    respect of the NGC Asset in the last Financial Year of
                    the Replacement Period (the "Deemed Charge") and the
                    matter shall be referred to the Director for
                    determination.  If the Director determines that the
                    Connection Charges payable in respect of such NGC Asset
                    should be:

                    (i)  less than the Deemed Charge then NGC shall repay
                         to the User the difference between the Deemed
                         Charge and the amount so determined by the
                         Director together with interest at the Base Rate,
                         for the period from when the User started to pay
                         the Deemed Charge until the date of payment;

                    (ii) greater than the Deemed Charge then the User shall
                         pay the difference to NGC together with interest
                         at the Base Rate for the period from when the User
                         started to pay the Deemed Charge until the date of
                         payment.

          3.5  Where the Connection Charges are payable in respect of NGC
               Assets:

               (a)  replaced in accordance with paragraph 3.3 above; or

               (b)  retained in accordance with paragraph 3.3 above; then

               NGC shall except in the circumstances in paragraph 3.4(b)
               give the User not less than 2 months prior written notice of
               such varied charges and specify the date upon which such
               charges become effective.  The User shall pay such varied
               charges and Appendices A and B shall be amended
               automatically (and a copy sent to the User) to reflect such
               revised charges with effect from the dates notified to the
               User by NGC.  Where NGC is in negotiation with the User in
               accordance with paragraph 3.4(b) then it shall give such
               notice as is reasonably practicable in the circumstances.

               -------------------

          4.1  The expressions set out below shall have the meanings shown:

               "Termination Amount"     shall be the sum calculated to be
                                        equal to the aggregate of the
                                        following:

                                        (a)  in respect of NGC Assets:

                                             (i)  shown in Appendix A to

                                                  Agreement and which in
                                                  NGC's reasonable opinion
                                                  are no longer required by
                                                  NGC to enable NGC to

                                                  end of the Financial Year
                                                  in which termination
                                                  occurs (on the assumption
                                                  that the sums specified
                                                  in paragraph 4.1(b) will
                                                  be paid), plus (bb) a sum
                                                  equal to the reasonable
                                                  costs of removing such
                                                  NGC Assets and of making

                                                  reasonable opinion cannot
                                                  be removed ("Type B
                                                  Assets") as a result of
                                                  the termination, a sum
                                                  equal to the product of
                                                  the Asset Allocation
                                                  Factor multiplied by the

                                                  incurred by NGC in

                                             termination occurs.

               "Asset Allocation Factor"     means in respect of each NGC
                                             Asset specified in Appendix A
                                             to this Supplemental Agreement
                                             the figure expressed as a
                                             percentage appearing in the
                                             column headed Allocation and
                                             immediately adjacent to the
                                             description of the NGC Asset
                                             to which it relates.

          4.2  In the event that a Termination Amount specified in
               paragraph 4.1(a)(i) is paid, in respect of Type A Assets,
               and subsequently NGC re-uses such NGC Assets in respect of
               which such payment has been made at the same or another
               Connection Site then NGC shall pay to the User a sum equal
               to the lower of:

               (i)  the Termination Amount paid in respect of such NGC
                    Asset; or

               (ii) the Net Asset Value attributed to such NGC Asset for
                    charging purposes upon its re-use;

                    less any reasonable costs incurred by NGC in respect of
                    storage.  NGC shall use its reasonable endeavors to re-
                    use such NGC Assets.

          4.3  In the event that a Termination Amount specified in
               paragraph 4.1(a)(ii) above is paid in respect of Type B
               Assets and these are subsequently re-used then NGC shall pay
               to the User a sum equal to the lower of:

               (i)  the Termination Amount paid in respect of such NGC
                    Assets; or

               (ii) the Net Asset Value attributed to such NGC Asset for
                    charging purposes upon its re-use.

          4.4  For the purposes of paragraphs 4.2 and 4.3 re-use shall not
               occur where any NGC Asset remains connected for the purpose
               of providing a continuing connection for other Users
               connected to the NGC Transmission System at the Connection
               Site at the date of termination.  However in the event of
               any User requiring a continued connection modifying its
               requirements or another User connecting at the Connection
               Site and the NGC Assets in respect of which a payment has
               been made are required for this modification this shall
               constitute re-use.

          4.5  NGC shall be under no obligation to rebate any of the
               Termination Amounts described in paragraph 4.1(b) except to
               the extent that Connection and/or Transmission Network Use
               of System Charges are subsequently received in respect of
               NGC Assets in relation to which such Termination Amounts
               have been paid to NGC during the Financial Year in which
               termination has occurred.

          4.6  Upon request in writing, and at the cost of the User, NGC
               shall issue a certificate no more frequently than  once each
               calendar year indicating whether or not such assets have or
               have not been re-used.  If NGC at any time decide that it is
               not economic to retain any Plant and Apparatus constituting
               any NGC Asset in respect of which Termination Amounts have
               been paid it may at its reasonable discretion dispose of the
               said Plant and Apparatus.  Where NGC decides to so dispose
               of such Plant and Apparatus it shall where the Plant and/or
               Apparatus is disposed of in a state where it is capable of
               re-use pay to the User an appropriate proportion of any sale
               proceeds received in respect thereof.

          5.   Deductions
               ----------

               In respect of any NGC Engineering Charges which have been
               paid by the User in connection with a Connection Application
               or under Sub-Clause 2.4 of the Supplemental Agreement Type 2
               NGC shall reduce the amount of Connection Charges payable by
               the User in relation to the respective Connection Site on 1
               April in each of the first 3 years (or such other period as
               may be agreed between NGC and the User) of the payment of
               such Connection Charges by an amount equal on each occasion
               to one third of such NGC Engineering Charges.

          Part 2 - Transmission Services Use of System Charges
          ----------------------------------------------------

          Introduction
          ------------

          Under the terms of this Supplemental Agreement the User is liable
          to pay Transmission Services Use of System Charges.  The basis
          upon which Transmission Services Use of System Charges are levied
          and the calculation methodology and rules which will be used to
          quantify those charges are set out in the statement issued by NGC
          under paragraphs 1 and 2 of Condition 10 to the Transmission
          License.

          1.   Reconciliation
               --------------

          1.1  At any time after the Payment Date NGC may submit to the
               User, and shall submit to the User at the written request of
               the User, a Statement (which may form part of an invoice or
               other document) in respect of any Settlement Day (a
               "Reconciliation Statement") showing:

               (a)  each Settlement Day in respect of which there has been
                    a change (for any reason) in the value of any parameter

                    System Charges paid in respect of that Settlement Day
                    equal to the payment which would have been payable had
                    the invoice prepared pursuant to Clause 5.4.1 of this
                    Supplemental Agreement been prepared on the basis of
                    the changed parameter;

               (c)  whether the reconciliation payment represents an amount

          1.3  The right to submit a Reconciliation Statement and the
               consequential invoices and/or credit notes shall survive the
               termination of this Supplemental Agreement and the parties
               agree that the provisions of ties Appendix E Part 2 shall

               the date of termination being the applicable version, in the
               case of any amendments).

                                   shall be notified by NGC to the User in

                         User in accordance with the terms of:

                         (a)  this Supplemental Agreement shall relieve it
                              of its obligations to provide such security
                              under the terms of any other Supplemental
                              Agreement to which the User is a party; and

                         (b)  any other Supplemental Agreement to which the
                              User is a party shall relieve it of its
                              obligations to provide such security under
                              the terms of this Supplemental Agreement;

                         in each case, to the extent of the security
                         provided to NGC pursuant to this Appendix or the
                         same provision under the terms of any other
                         Supplemental Agreement made between NGC and the

               1.1.4     The provisions of this Part 3 of Appendix E shall
                         be in addition to any other requirements to
                         provide security in respect of any other sums due
                         under the terms of this Supplemental Agreement.

          1.2  Maintenance of Security Cover
               -----------------------------

               Where the User is required to provide Security Cover in
               accordance with the terms of paragraph 1.1 it shall at all
               times thereafter maintain a Security Amount equal to or more
               than the Security Cover applicable to it.  Immediately upon
               any reduction occurring in the Security Amount provided by
               the User or any Letter of Credit or Qualifying Guarantee
               being for any reason drawn down or demanded respectively,
               the User will procure that new Letters of Credit or
               Qualifying Guarantees are issued or existing Letters of
               Credit or Qualifying Guarantees are reinstated (to the
               satisfaction of NGC) to their full value or cash is placed
               to the credit of the Escrow Account in an amount required to
               restore the Security Amount to an amount at least equal to
               the Security Cover applicable to the User, and in such
               proportions of Letters of Credit, Qualifying Guarantees
               and/or cash as the User may determine.  Not later than 10
               Business Days before any outstanding Letter of Credit and/or
               Qualifying Guarantee is due to expire, the User shall
               procure to the satisfaction of NGC that its required
               Security Amount will be available for a further period of
               not less than 6 months which may be done in one of the
               following ways:

               1.2.1     subject to the issuing bank continuing to have an
                         Approved Credit Rating provide NGC with
                         confirmation from the issuing bank that the
                         validity of the Letter of Credit has been extended
                         for a period of not less than 6 months on the same
                         terms and otherwise for such amount as is required
                         by this Part 3; or

               1.2.2     provide NGC with a new Letter of Credit issued by
                         an issuing bank with an Approved Credit Rating for
                         an amount at least equal to the required Security
                         Amount applicable to it (less its balance on the
                         Escrow Account) which Letter of Credit shall be
                         available for a period of not less than 6 months;
                         or

               1.2.3     subject to the entity issuing the Qualifying
                         Guarantee continuing to have an Approved Credit
                         Rating provide NGC with confirmation from the
                         issuing  entity that the validity of the Guarantee
                         has been extended for a period of not less than 6
                         months on the same terms and otherwise for such
                         amount as is required by this Part 3; or

               1.2.4     provide NGC with a new Qualifying Guarantee for an
                         amount at least equal to the required Security
                         Amount applicable to it (less its balance on the
                         Escrow Account) which Qualifying Guarantee shall
                         be available for a period of not less than 6
                         months; or

               1.2.5     procure such transfer to NGC for credit to the
                         Escrow Account of an amount as shall ensure that
                         the credit balance applicable to the User and
                         standing to the credit of the Escrow Account shall
                         be at least equal to the required Security Amount.

          1.3  Failure to supply or maintain Security Cover
               --------------------------------------------

               If the User fails at any time to provide or maintain
               Security Cover to the satisfaction of NGC in accordance with
               the provisions of this Part 3, NGC may at any time while
               such default continues and if at such time any Letter of
               Credit and/or Qualifying Guarantee forming part of the
               Security Cover is due to expire within nine Business Days
               immediately, and without notice to the User, demand payment
               of the entire amount of any outstanding Letter of Credit
               and/or Qualifying Guarantee and shall credit the proceeds of
               the Letter of Credit and/or Qualifying Guarantee to the
               Escrow Account.

          1.4  Substitute Letter of Credit or Qualifying Guarantee
               ---------------------------------------------------

               1.4.1     If the bank issuing the User's Letter of Credit
                         ceases to have the credit rating set out in the
                         definition of Letter of Credit in Clause 1.1 of
                         this Supplemental Agreement such User shall
                         forthwith procure the issue of a substitute Letter
                         of Credit by a bank that has such a credit rating
                         or a Qualifying Guarantee or transfer to NGC cash
                         to be credited to the Escrow Account.

               1.4.2     If the entity providing the User's Qualifying
                         Guarantee ceases to have an Approved Credit Rating
                         the User shall forthwith procure a replacement
                         Qualifying Guarantee from an entity with such a
                         credit rating or a Letter of Credit or transfer to
                         NGC cash to be credited to the Escrow Account.

          2.   Credit Monitoring
               -----------------

          2.1  Determination of Security Cover
               -------------------------------

               The amount of Security Cover which the User shall be
               required to maintain shall be determined from time to time
               by NGC in accordance with this Part 3 on the basis of the
               criteria set out in paragraph 2.2 and shall be notified to
               the User.

          2.2  Criteria for provision of Security Cover
               ----------------------------------------

               If paragraph 1.1.2 applies, the amount of Security Cover
               required to be provided by the User in respect of this and
               any other Supplemental Agreement to which the User is a
               party shall be provided in an amount to be reasonably
               assessed by NGC as the aggregate amount reasonably
               anticipated by NGC as being payable by the User pursuant to
               all Supplemental Agreements to which the User is a party in
               respect of the Transmission Services Use of System Charges
               referred to in Part 2 of Appendix D over a 28 day period.

          2.3  Six Monthly Variation
               ---------------------

               In respect of paragraph 2.2 NGC shall calculate the amount
               for the two six-month periods commencing 1st April and 1st
               October in each year and shall advise the User accordingly.

          2.4  Review of Security Cover
               ------------------------

               NGC shall keep under review the Security Cover relating to
               the User and shall promptly advise the User whenever the
               Security Amount maintained by the User is more or less than
               the amount required to be maintained pursuant to paragraph 2
               of this Part 3.

          2.5  Increase or Decrease of Security Cover
               --------------------------------------

               If after considering any representations which may be made
               by the User, NGC reasonably determines that the User's
               Security Cover should be increased or decreased, it shall so
               notify the User.  If NGC so determines that such Security
               Cover should be decreased and the User consents then that
               reduction shall take place.  NGC shall consent to an
               appropriate reduction in the available amount of any
               outstanding Qualifying Guarantee or Letter of Credit and/or
               shall repay to the User such part of the deposit held in the
               Escrow Account for the account of the User (together with
               all accrued interest on the part to be repaid) sufficient to
               reduce the User's Security Amount to the level of Security
               Cover applicable to it.  If NGC so determines that the
               User's Security Cover should be increased, the User shall,
               within five Business Days of notice as aforesaid, procure an
               additional or replacement Qualifying Guarantee or Letter of
               Credit or transfer to NGC cash to be credited to the Escrow
               Account in an amount sufficient to increase its Security
               Amount so as to be at least equal to the level of Security
               Cover applicable to it.

          2.6  Notification in respect of Security Cover
               -----------------------------------------

               NGC shall notify the User promptly if:

               2.6.1     the User fails to provide, maintain, extend or
                         renew a Qualifying Guarantee or a Letter of Credit
                         which it is required to provide, maintain, extend
                         or renew pursuant to paragraphs 1 or 2;

               2.6.2     NGC shall make a demand under any such Qualifying
                         Guarantee or a call under a Letter of Credit; or

               2.6.3     NGC becomes aware that the User (a) shall cease to
                         have an Approved Credit Rating, or (b) shall be
                         placed on credit watch by the relevant credit
                         rating agency (or becomes subject to an equivalent
                         procedure) which in any case casts doubt on the
                         User retaining an Approved Credit Rating, or (c)
                         shall be in default under the additional or
                         alternative security required to be provided
                         pursuant to this Part 3; or

               2.6.4     NGC becomes aware that any bank that has issued a
                         Letter of Credit which has not expired shall cease
                         to have the credit rating required by this
                         Appendix; or

               2.6.5     NGC becomes aware that any entity providing a
                         Qualifying Guarantee which has not expired shall
                         cease to have an Approved Credit Rating.

               Provided always that the failure by NGC to notify the User
               pursuant to this paragraph 2.6 shall not relieve the User of
               its obligations under and in accordance with the terms of
               this Appendix.

          2.7  Release from Security Cover Obligations
               ---------------------------------------

               Upon the User ceasing to be a party to the Master Agreement
               and provided that all amounts owed by the User in respect of
               the Transmission Services Use of System Charges have been
               duly and finally paid and that it is not otherwise in
               default in any respect of any Transmission Services Use of
               System Charges (including interest) payable under the terms
               of any Supplemental Agreement, the User shall be released
               from the obligation to maintain Security Cover and NGC shall
               consent to the revocation of any outstanding Qualifying
               Guarantee or Letter of Credit and shall repay to the User
               the balance (including interest credited thereto) standing
               to the credit of the User on the Escrow Account at that
               date.

          3.   Payment Default
               ---------------

               If by 1230 hours on any Payment Date, NGC has been notified
               by the User or it otherwise has reason to believe that the
               User will not have remitted to it by close of banking
               business on the Payment Date all or any part ("the amount in
               default") of any amount which has been notified by NGC to
               the User as being payable by the User by way of the
               Transmission Services Use of System Charges on the relevant
               Payment Date, then NGC shall be entitled to act in
               accordance with the following provisions  (or whichever of
               them shall apply) in the order in which they appear until
               NGC is satisfied that the User has discharged its
               obligations in respect of the Transmission Services Use of
               System Charges under this Supplemental Agreement and/or any
               other Supplemental Agreement to which the User is a party
               which are payable in respect of the relevant Settlement Day:

               (a)  NGC may to the extent that the User is entitled to
                    receive payment from NGC pursuant to this Supplemental
                    Agreement and/or any other Supplemental Agreement to
                    which the User is a party (unless it reasonably
                    believes that such setoff shall be unlawful) set off
                    the amount of such entitlement against the amount in
                    default;

               (b)  NGC shall be entitled to set off the amount of funds
                    then standing to the credit of the Escrow Account to
                    the extent that it represents Security Cover provided
                    by the User in accordance with paragraph 2.1.2 against
                    the Transmission Services Use of System Charges unpaid
                    by the User and for that purpose NGC shall be entitled
                    to transfer any such amount from the Escrow Account to
                    any other account of NGC at its absolute discretion and
                    shall notify the User accordingly;

               (c)  NGC may demand payment under any outstanding Letter of
                    Credit supplied by the User in a sum not exceeding the
                    available amount of all such Letters of Credit;

               (d)  NGC may demand payment under any outstanding Qualifying
                    Guarantee provided for the benefit of the User pursuant
                    to paragraph 1.1.2(a).

          4.   Utilisation of Funds
               --------------------

               In addition to the provisions of paragraph 3 above if NGC
               serves a notice of default under the terms of Clause 17.6A
               of a Type 1 Supplemental Agreement and/or notice of
               termination under Clause 17.7 of a Type 1 Supplemental
               Agreement (or the equivalent Clauses in a Supplemental
               Agreement other than a Type 1 Supplemental Agreement) then
               NGC shall be entitled to demand payment of any of the
               Transmission Services Use of System Charges which are
               outstanding whether or not the Payment Date in respect of
               them shall have passed and:

               (i)  make demand under any outstanding Qualifying Guarantee
                    or a call under any outstanding Letter of Credit
                    supplied by the User; and

               (ii) to set off the funds in the Escrow Account to the
                    extent that they represent Security Cover provided by
                    the User against the Transmission Services Use of
                    System Charges unpaid by the User and for that purpose
                    NGC shall be entitled to transfer any such amount from
                    the Escrow Account to any other account of NGC as it
                    shall in its sole discretion think fit.

               ------------------------
          8.1  Emergency Deenergisation requested by NGC:
               -----------------------------------------
          If, in the reasonable opinion of NGC, the condition or manner of
          operation of the NGC Transmission System or the User's System (if any)
          poses an immediate threat of injury or material damage to any person

          9.   DEENERGISATION AND DISCONNECTION
               --------------------------------
          9.1  Breach by the User:
               ------------------
          If the User shall be in breach of the provisions of this Supplemental
          Agreement and such breach causes or can reasonably be expected to
          cause a material adverse effect on the business or condition of NGC or
          other Users or the NGC Transmission System or User Systems then NGC
          may:-

          (i)  where the breach is capable of remedy, give written notice to the
               User specifying in reasonable detail the nature of the breach and
               requiring the User within 28 days after receipt of such notice to
               remedy the breach or within any longer period agreed between NGC

               withheld or delayed; or

          (ii) where the breach is incapable of remedy, give written notice to
               the User specifying in reasonable detail the nature of the breach
               and the reasons why the breach is incapable of remedy and
               requiring the User within 5 Business Days after the receipt of
               such notice to undertake to NGC not to repeat the breach.

          9.2  De-Energisation
               ---------------
          If:-
               (a)  the User fails to comply with the terms of any valid notice
                    served on it by NGC in accordance with Sub-Clause 9.1(i) or
                    is in breach of any undertaking given in accordance with
                    Sub-Clause 9.1(ii) and such breach causes or can be
                    reasonably expected to cause a material adverse effect on
                    the business or condition of NGC or other Users or the NGC
                    Transmission or User Systems; or

               (b)  five Business Days have elapsed the date of any valid notice
                    served on the User in accordance with Sub-Clause 9.2(ii) and
                    no undertaking is given by the User in accordance with Sub-
                    Clause 9.2(ii);

          NGC may request the owner of the Distribution System to which the User
          is connected to De-Energise the User's Plant at that site upon expiry
          of at least 48 hours prior written notice to the User, provided that
          at the time of expiry of such notice the breach concerned remains
          unremedied and that neither the User nor NGC has referred the matter
          to the Dispute Resolution Procedure.  In such event NGC may request
          the owner of the Distribution System to which the User is connected to
          De-Energise the User's Plant at that site forthwith following
          completion of the Dispute Resolution Procedure and final determination
          of the dispute in NGC's favour.

          9.3  NGC Transmission Licence
               ------------------------
          If a breach of the nature referred to in Sub-Clause 9.1 continues to
          the extent that it places or seriously threatens to place in the
          immediate future NGC in breach of the NGC Transmission Licence, NGC
          may request the owner of the Distribution System to which the User's
          Customers are connected to De-Energise such User's Customers upon the
          expiry of at least 12 hours prior written notice to the User, provided
          that at the time of expiry of such notice the breach concerned remains
          unremedied.

          9.4  Re-Energisation Disputes
               ------------------------
          If, following any De-Energisation pursuant to this Clause 9, a User
          applies to NGC for NGC to issue instructions that the User's
          Customer(s) be Re-Energised and is refused or is offered terms which
          the User does not accept, this shall be recognised as a dispute over
          the terms for use of system which the User may refer to the Director
          for determination under the NGC Transmission Licence.  If the User
          accepts any terms offered by NGC or settled by the Director pursuant
          to any such reference, NGC shall request the owner of the Distribution
          System to which the User's Plant is connected to Re-Energise the
          User's Plant forthwith after any request from the User for NGC to do
          so.

          9.5  Event of Default
               ----------------
          If the breach which led to any De-Energisation pursuant to this Clause
          9 remains unremedied at the expiry of at least 6 months after the date
          of such De-Energisation, NGC may declare by notice in writing to the
          User that such breach has become an event of default provided that:-

               (a)  all disputes arising out of the subject-matter to this
                    Clause 9 which are referred to the Dispute Resolution
                    Procedure have then been finally determined in favour of
                    NGC; and

               (b)  any reference to the Director pursuant to Sub-Clause 8.4 has
                    then been finally determined in favour of NGC or any terms
                    settled by the Director pursuant to such application have
                    not been accepted by the User.

          9.6  Disconnection
               -------------
          Once NGC has given a valid notice of in event of default pursuant to

          1.2.1     On or before 1 March in each Financial Year NGC shall
          promptly calculate on the basis set out in the statement published by
          NGC in accordance with Licence Condition 10 of the Transmission
          Licence the Demand related or Generation related Transmission Network
          Use of System Charges (as the case may be) that would have been
          payable by the User during each month during that Financial Year if
          those charges had been calculated on the basis of the actual Demand
          data or the User's highest declared Registered Capacity recorded
          during the Financial Year in respect of the forecasts which had
          previously been provided by the User in accordance with paragraph 1.1
          (the "Actual Amount").  NGC shall then compare the Actual Amount with
          the amount of Demand related or Generation related Transmission
          Network Use of System Charges (as the case may be) paid during each
          month during that Financial Year by the User (the "Notional Amount").

          1.2.2     As soon as reasonably practicable and in any event by 1st
          March in each Financial Year NGC shall then prepare an initial
          reconciliation statement and send it to the User.  Such statement
          shall specify the Actual Amount and the Notional Amount for each month
          during the relevant Financial Year and, in reasonable detail, the
          information from which such amounts were derived and the manner in
          which they were calculated.

          1.2.3     Together with the initial reconciliation statement NGC shall
          issue a credit note in relation to any sum shown by the reconciliation
          statement to be due to the User or an invoice in respect of sums due
          to NGC and in each case interest thereon calculated pursuant to
          paragraph 1.2.5 below.

          1.2.4     Invoices issued under paragraph 1.2.3 above and 1.2.5 below
          shall be payable on or before 31st March in the Financial Year to

               (a)  the User shall, following receipt of an appropriate invoice,
               pay to NGC an amount equal to the amount (if any) by which the
               aggregate Actual Amount exceeds the aggregate Notional Amount;
               and

               (b)  NGC shall issue the User with a credit note for an amount
               equal to the amount (if any) by which the aggregate Notional
               Amount exceeds the aggregate Actual Amount.

          Interest shall be payable by the paying Party to the other on such
          amounts from the date of payment applicable to the month concerned
          until the date of actual payment of such amounts and such interest
          shall be calculated on a daily basis at a rate equal to the Base Rate
          during such period.

     2.   Revision of Charges
          -------------------

          2.1  To the extent permitted by the Transmission License and this
               Agreement NGC may revise its Connection Charges and Transmission
               Network Use of System Charges or the basis of their calculation
               including issuing revisions to Appendices A, B, C and D (or D1 if
               appropriate) hereto.  On or before 31st October in each Financial
               Year NGC shall notify the User in writing of the intended basis
               of calculation to be used by NGC in the following Financial Year
               together with time periods over which the data required to be
               provided pursuant to paragraph 1 of this Appendix E is required
               and shall consult with the User concerning the same.  On or
               before 30th November in each Financial Year NGC shall confirm to
               the User the basis of calculation to be used in the following
               Financial Year.

          2.2  NGC shall give the User not less than 2 months prior written
               notice of any revised charges including revisions to Appendices
               A, B, C and D (or D1 if appropriate) hereto, which notice shall
               specify the date upon which such revisions become effective
               (which may be at any time).  The User shall pay any such revised
               charges and Appendix A, B, C, D (and/or D1 as appropriate) shall
               be amended automatically (and a copy sent to the User) to reflect
               any changes to such Appendices with effect from the date
               specified in such notice.

          2.3  Subject to the provisions of paragraph 3.2 below if in the
               reasonable opinion of NGC any development replacement,
               renovation, alteration, construction or other work to the NGC
               Transmission System or termination on of a Supplemental Agreement
               by another User or an alteration to the requirements of the User
               or any other User means that to ensure that NGC is charging in
               accordance with the provisions of the Statement pursuant to
               Condition 10 of the Transmission Licence NGC needs to vary the
               Connection Charges payable by the User in relation to the
               Connection Site then NGC shall have the right to vary such
               charges accordingly upon giving to the User not less than 2
               months prior written notice.  Such notice shall be deemed to be a
               revised Connection Offer and before any such variation becomes
               effective the provisions of Sub-Clauses 11.3 to 11.4 of the
               Master Agreement shall apply mutatis mutandis.  Following any
               such variation the provisions of Appendices A and B shall be
               amended automatically (and a copy sent to the User) to reflect
               such variation with effect from the date such variation comes
               into effect.

     3.   Replacement of NGC Assets
          -------------------------
          3.1  Appendix A specifies the age of each of the NGC Assets at the
          Connection Site at the date of this Supplemental Agreement.  NGC
          Connection Charges are calculated on the assumption that NGC Assets
          will not require replacement until the expiry of the Replacement
          Period applicable to each NGC Asset concerned and such period has been
          agreed between NGC and the User.

          3.2  Where in NGC's reasonable opinion an NGC Asset require
          replacement before the expiry of its Replacement Period NGC shall,
          with the prior written approval of the User (except where in NGC's
          reasonable opinion such replacement is necessary in which case such
          approval shall not be required but in such case the User shall have
          the right to Disconnect) have the night to replace the NGC Asset at no
          additional cost to the User until expiry of its original Replacement
          Period.  Upon expiry of such original Replacement Period NGC shall be
          entitled to vary the Connection Charges in respect of the replaced NGC
          Asset so that they are calculated on the basis of the then Net Asset
          Value of such NGC Assets.  NGC shall give the User not less than 2
          months prior written notice of such varied charges which notice shall
          specify the date upon which such increase or reduction (as the case
          may be) becomes effective.  The User shall pay such varied charges and
          Appendices A and B shall be amended automatically (and a copy sent to
          the User) to reflect such revised charges with effect from the date
          specified in such notice.

          3.3  Upon the expiry of the Replacement Period of any NGC Asset-

               (a)  (i)  if in NGC's reasonable opinion to enable NGC to comply
                         with its licence and statutory obligations it is
                         necessary to replace such NGC Asset; or

                    (ii) if such NGC Asset is to be left in service

               then NGC shall give written notice of this and that it will,
               unless within 3 months of the receipt of such notice the User
               objects in writing to the proposal, replace or retain (as the
               case may be) such NGC Asset.

               (b)  the User may request that NGC replaces the Asset.

          3.4  Where the User serves a counter notice pursuant to paragraph 3.3
               above then NGC shall:-

               (a)  keep the NGC Asset in service; and

               (b)  negotiate with the User in good faith with regard to the
               Connection Charges applicable to such NGC Asset.

          In the event that NGC and the User fail to agree the level of such
          Connection Charges in accordance with paragraph 3.4(b) above then the
          User shall pay Connection Charges to NGC in respect of such NGC Asset
          equal to the Connection Charges payable by the User in respect of the
          NGC Asset in the last Financial Year of the Replacement Period (the
          "Deemed Charge") and the matter shall be referred to the Director for
          determination.  If the Director determines that the Connection Charges
          payable in respect of such NGC Asset should be:-

                    (i)  less than the Deemed Charge then NGC shall repay to the
                    User the difference between the Deemed Charge and the amount
                    so determined by the Director together with interest at the
                    Base Rate, for the period from when the User started to pay
                    the Deemed Charge until the date of payment;

                    (ii) greater than the Deemed Charge then the User shall pay
                    the difference to NGC together with interest at the Base
                    Rate for the period from when the User started to pay the
                    Deemed Charge until the date of payment.

          3.5  Where the Connection Charges are payable in respect of NGC
               Assets:

               (a)  replaced in accordance with paragraph 3.3 above; or

               (b)  retained in accordance with paragraph 3.3 above; then

          NGC shall except in the circumstances in paragraph 3.4(b) give the
          User not less than 2 months prior written notice of such varied
          charges and specify the date upon which such charges become
          effective.  The User shall pay such varied charges and Appendices A
          and B shall be amended automatically (and a copy sent to the User) to
          reflect such revised charges with effect from the dates notified to
          the User by NGC.  Where NGC is in negotiation with the User in
          accordance with paragraph 3.4(b) then it shall give such notice as is
          reasonable practicable in the circumstances.

     4.   Termination Amounts
          -------------------

          4.1  The expressions set out below shall have the meanings shown:-

          "Termination Amount"     shall be the sum calculated to be equal to
                                   the aggregate of the following:-

                              (a)  in respect of NGC Assets:-

                                   (i)  shown in Appendix A to the Supplemental
                                        Agreement and which, in NGC's reasonable
                                        opinion are no longer required by NGC to
                                        enable NGC to comply with its Licence
                                        Standards, and can therefore be removed
                                        ("Type A Assets"), (aa) the Net Asset
                                        Value of such NGC Asset as at the end of
                                        the Financial Year in which termination
                                        occurs (on the assumption that the sums
                                        specified in paragraph 4.1(b) will be
                                        paid), plus (bb) a sum equal to the
                                        reasonable costs of removing such NGC
                                        Assets and of making good the remaining
                                        Plant and Apparatus at the Connection
                                        Site following the removal of any Type A
                                        Assets;

                                   (ii) in Appendix A to the Supplemental
                                        Agreement and which in NGC's reasonable
                                        opinion cannot be removed ("Type B
                                        Assets") as a result of the termination,
                                        a sum equal to the product of the Asset
                                        Allocation Factor multiplied by the Net
                                        Asset Value of that NGC Asset as at the
                                        end of the Financial Year in which
                                        termination occurs; and

                                   (iii)     in relation to NGC Assets

                                        (aa) which NGC has determined to replace
                                             upon the expiry of the relevant
                                             Replacement Period in accordance
                                             with paragraph 3.3; and

                                        (bb) in respect of which no counter
                                             notice has been served by the User
                                             pursuant to paragraph 3.3; and

                                        (cc) the User has served in accordance
                                             with the provisions of this
                                             Supplemental Agreement a notice to
                                             Disconnect in respect of the
                                             Connection Site at which the NGC
                                             Assets were located; and

                                        (dd) due to the timing of the
                                             replacement of such NGC Assets, no
                                             Connection Charges will have become
                                             payable in respect of such NGC
                                             Assets by the User by the date of
                                             termination;

                                        the reasonable costs incurred by NGC in
                                        connection with the installation of such
                                        NGC Assets.

                              (b)  the Connection Charges and Use of System
                                   Charges for the Financial Year in which
                                   termination occurs.

          "Asset Allocation Factor"     means in respect of each NGC Asset
                                        specified in Appendix A to this
                                        Supplemental Agreement the figure
                                        expensed as a percentage applying in the
                                        column headed Allocation and immediately
                                        adjacent to the description of the NGC
                                        Asset to which it relates.

          4.2  In the event that a Termination Amount specified in paragraph
          4.1(a)(i) is paid, in respect of Type A Assets, and subsequently NGC
          re-uses such NGC Assets in respect of which such payment has been made
          at the same or another Connection Site then NGC shall pay to the User
          a sum equal to the lower of -

          (i)  the Termination Amount paid in respect of such NGC Asset; or

          (ii) the Net Asset Value attributed to such NGC Asset for charging
               purposes upon its re-use;

          less any reasonable costs incurred by NGC in respect of storage.  NGC
          shall use its reasonable endeavours to re-use such NGC Assets.

          4.3  In the event that a Termination Amount specified in paragraph
          4.1(a)(ii) above is paid in respect of Type B Assets and these are
          subsequently re-used then NGC shall pay to the User a sum equal to the
          lower of:

          (i)  the Termination Amount paid in respect of such NGC Assets; or

          (ii) the Net Asset Value attributed to such NGC Asset for charging
               purposes upon its re-use.

          4.4  For the purposes of paragraphs 4.2 and 4.3 re-use shall not occur
          where any NGC Asset remains connected for the purpose of providing a
          continuing connection for other Users connected to the NGC
          Transmission System at the Connection Site at the date of
          termination.  However in the event of any User requiring a continued
          connection modifying its requirements or another User connecting at
          the Connection Site and the NGC Assets in respect of which a payment
          has been made are required for this modification this shall constitute
          re-use.

          4.5  NGC shall be under no obligation to rebate any of the Termination
          Amounts described in paragraph 4.1(b) except to the extent that
          Connection and/or Transmission Network Use of System Charges are
          subsequently received in respect of NGC Assets in relation to which
          such Termination Amounts have been paid to NGC during the Financial
          Year in which termination has occurred.

          4.6  Upon request in writing, and at the cost of the User, NGC shall
          issue a certificate no more frequently than once each calendar year
          indicating whether or not such assets have or have not been re-used.
          If NGC at any time decide that it is not economic to retain any Plant
          and Apparatus constituting any NGC Asset in respect of which
          Termination Amounts have been paid it may at its reasonable discretion
          dispose of the said Plant and Apparatus.  Where NGC decides to so
          dispose of such Plant and Apparatus it shall where the Plant and/or
          Apparatus is disposed of in a state where it is capable of re-use pay
          to the User an appropriate proportion of any sale proceeds received in
          respect thereof.


     5.   Deductions
          ----------

          In respect of any NGC Engineering Charges which have been paid by the
          User in connection with a Connection Application or under Sub-Clause
          2.4 of the Supplemental Agreement Type 2 NGC shall reduce the amount
          of Connection Charges payable by the User in relation to the
          respective Connection Site on 1 April in each of the first 3 years (or
          such other period as may be agreed between NGC and the User) of the
          payment of such Connection Charges by an amount equal on each occasion
          to one third of such NGC Engineering Charges.

     Part 2 - Transmission Services Use of System Charges
     ----------------------------------------------------

     Introduction
     ------------

     Under the terms of this Supplemental Agreement the User is liable to pay
     Transmission Services Use of System Charges.  The basis upon which
     Transmission Services Use of System Charges are levied and the calculation
     methodology and rules which will be used to quantify those charges are set
     out in the statement issued by NGC under paragraphs 1 and 2 of Condition 10
     to the Transmission Licence.

     1.   Reconciliation
          --------------

          1.1  At any time after the Payment Date NGC may submit to the User,
          and shall submit to the User at the written request of the User, a
          Statement (which may form part of an invoice or other document) in
          respect of any Settlement Day (a "Reconciliation Statement") showing:-

               (a)  each Settlement Day in respect of which there has been a
                    change (for any reason) in the value of any parameter
                    originally used in the calculation of the Transmission Use
                    of System Charges in respect of such Settlement Day,
                    together with details of the value of the old and new
                    parameter;

               (b)  the amount of any reconciliation payments (if any) required
                    to make theTransmission Services Use of System Charges paid
                    in respect of that Settlement Day equal to the payment which
                    would have been payable had the invoice prepared pursuant to
                    Clause 5.4.1 of this Supplemental Agreement been prepared on
                    the basis of the changed parameter;

               (c)  whether the reconciliation payment represents an amount
                    owing by NGC to the User or by the User to NGC;

               (d)  the amount of interest accruing on such reconciliation
                    payment calculated in accordance with this paragraph 1.1
                    below.

               Interest payable in respect of any reconciliation payment shall
               accrue from and including the relevant Payment Date up to but
               excluding the date upon which the amounts specified in the
               Reconciliation Statement are paid, and shall be at a rate equal
               to the Base Rate for the time being and from time to time.
               Interest shall accrue from day to day.

          1.2  Together with the Reconciliation Statement in the case of sums
     due:-

          (a)  from the User to NGC, NGC shall:-

               (i)  send the User an invoice in relation to any sums shown by
                    the Reconciliation Statement to be due to NGC and interest
                    thereon calculated in accordance with paragraph 1.1; or

               (ii) include those sums due in another invoice; and

          (b)  from NGC to the User, forthwith following the issue of any
               Reconciliation Statement, NGC shall:-

               (i)  issue a credit note in relation to any sum shown by the
                    Reconciliation Statement to be due to the User and interest
                    thereon calculated in accordance with paragraph 1.1; or

               (ii) include those sums due to the User as a credit in an invoice
                    from NGC to the User.

          1.3  The right to submit a Reconciliation Statement and the
          consequential invoices and/or credit notes shall survive the
          termination of this Supplemental Agreement and the parties agree that
          the provisions of this Appendix E Part 2 shall remain in full force
          and effect and shall continue to bind them after such termination (the
          version in existence as at the date of termination being the
          applicable version, in the case of any amendments).

     2.   Reconciliation Payments
          -----------------------

          The User, or as the case may be, NGC, shall pay the amounts set out in
          the relevant invoice or credit note. either in accordance with the
          applicable requirements for payment of other sums due under that
          invoice in the case of sums shown in an invoice also dealing with
          other payments, or in other cases within 5 Business Days of the date
          of the Reconciliation Statement.

     3.   Revision of Charges
          -------------------

          On or before 31 October in each Financial Year NGC shall notify the
          User in writing of the intended basis of calculation to be used by NGC
          in calculating Transmission Services Use of System Charges for the
          following Financial Year and shall consult the User concerning the
          same.  On or before 30 November in each Financial Year NGC shall
          confirm to the User the basis of calculation to be used in calculating
          those charges for the Following Financial Year.

     Part 3

          time any Letter of Credit and/or Qualifying Guarantee forming part of
          the Security Cover is due to expire within nine Business Days

          entire amount of any outstanding Letter of Credit and/or Qualifying

                    ceases to have an Approved Credit Rating the User shall
                    forthwith procure a replacement Qualifying Guarantee from an

     2.   Credit Monitoring
          -----------------

     2.1  Determination of Security Cover
          -------------------------------

          The amount of Security Cover which the User shall be required to
          maintain shall be determined from time to time by NGC in accordance
          with this Part 3 on the basis of the criteria set out in paragraph 2.2
          and shall be notified to the User.

     2.2  Criteria for Provision of Security Cover
          ----------------------------------------

          If paragraph 1.1.2 applies, the amount of Security Cover required to
          be provided by the User in respect of this and any other Supplemental
          Agreement to which the User is a party shall be provided in an amount
          to be reasonably assessed by NGC as the aggregate amount reasonably
          anticipated by NGC as being payable by the User pursuant to all
          Supplemental Agreements to which the User is a party in respect of the
          Transmission Services Use of System Charges referred to in Part 2 of
          Appendix D over a 28 day period.

     2.3  Six Monthly Variation
          ---------------------

          In respect of paragraph 2.2 NGC shall calculate the amount for the two
          six-month periods commencing 1st April and 1st October in each year
          and shall advise the User accordingly.

     2.4  Review of Security Cover
          ------------------------

          NGC shall keep under review the Security Cover relating to the User
          and shall promptly advise the User whenever the Security Amount
          maintained by the User is more or less than the amount required to be
          maintained pursuant to paragraph 2 of this Part 3.

     2.5  Increase or Decrease of Security Cover
          --------------------------------------

          If after considering any representations which may be made by the
          User, NGC reasonably determines that the User's Security Cover should
          be increased or decreased, it shall so notify the User.  If NGC so
          determines that such Security Cover should be decreased and the User
          consents then that reduction shall take place.  NGC shall consent to
          an appropriate reduction in the available amount of any outstanding
          Qualifying Guarantee or Letter of Credit and/or shall repay to the
          User such part of the deposit held in the Escrow Account for the
          account of the User (together with all accrued interest on the part to
          be repaid) sufficient to reduce the User's Security Amount to he level
          of Security Cover applicable to it.  If NGC so determines that the
          User's Security Cover should be increased, the User shall, within five
          Business Days of notice as aforesaid, procure an additional or
          replacement Qualifying Guarantee or Letter of Credit or transfer to
          NGC cash to be credited to the Escrow Account in an amount sufficient
          to increase its Security Amount so as to be at least equal to the
          level of Security Cover applicable to it.

     2.6  Notification in respect of Security Cover
          -----------------------------------------

          NGC shall notify the User promptly if:-

          2.6.1     the User fails to provide, maintain, extend or renew a
                    Qualifying Guarantee or a Letter of Credit which it is
                    required to provide, maintain, extend or renew pursuant to
                    paragraphs 1 or 2;

          2.6.2     NGC shall make a demand under any such Qualifying Guarantee
                    or a call under a Letter of Credit; or

          2.6.3     NGC becomes aware that the User (a) shall cease to have an
                    Approved Credit or (b) shall be placed on credit watch by
                    the relevant credit rating agency (or becomes subject to an
                    equivalent procedure) which in any case casts doubt on the
                    User retaining an Approved Credit Rating, or (c) shall be in
                    default under the additional or alternative security
                    required to be provided pursuant to this Part 3; or

          2.6.4     NGC becomes aware that any bank that has issued a Letter of
                    Credit which has not expired shall cease to have the credit
                    rating required by this Appendix; or

          2.6.5     NGC becomes aware that any entity providing a Qualifying
                    Guarantee which has not expired shall cease to have an
                    Approved Credit Rating.

          Provided always that the failure by NGC to notify the User pursuant to
          this paragraph 2.6 shall not relieve the User of its obligations under
          and in accordance with the terms of this Appendix.

     2.7  Release from Security Cover Obligations
          ---------------------------------------

          Upon the User ceasing to be a party to the Master Agreement and
          provided that all amounts owed by the User in respect of the
          Transmission Services Use of System Charges have been duly and finally
          paid and that it is not otherwise in default in any respect of any
          Transmission Services Use of System Charges (including interest)
          payable under the terms of any Supplemental Agreement, the User shall
          be released from the obligation to maintain Security Cover and NGC
          shall consent to the revocation of any outstanding Qualifying
          Guarantee or Letter of Credit and shall repay to the User the balance
          (including interest credited thereto) standing to the credit of the
          User on the Escrow Account at that date.

     3.   Payment Default
          ---------------

          If, by 1230 hours on any Payment Date, NGC has been notified by the
          User or it otherwise has reason to believe that the User will not have
          remitted to it by close of banking business on the Payment Date all or
          any part ("the amount in default") of any amount which has been
          notified by NGC to the User as being payable by the User by way of the
          Transmission Services Use of System Charges on the relevant Payment
          Date, then NGC shall be entitled to act in accordance with the
          following provisions (or whichever of them shall apply) in the order
          in which they appear until NGC is satisfied that the User has
          discharged its obligations in respect of the Transmission Services Use
          of System Charges under this Supplemental Agreement and/or any other
          Supplemental Agreement to which the User is a party which are payable
          in respect of the relevant Settlement Day:-

          (a)  NGC may to the extent that the User is entitled to receive
               payment from NGC pursuant to this Supplemental Agreement and/or
               any other Supplemental Agreement to which the User is a party
               (unless it reasonably believes that such set-off shall be
               unlawful) set off the amount of such entitlement against the
               amount in default;

          (b)  NGC shall be entitled to set off the amount of funds then
               standing to the credit of the Escrow Account to the extent that
               it represents Security Cover provided by the User in accordance
               with paragraph 2.1.2 against the Transmission Services Use of
               System Charges unpaid by the User and for that purpose NGC shall
               be entitled to transfer any such amount from the Escrow Account
               to any other account of NGC at its absolute discretion and shall
               notify the User accordingly;

          (c)  NGC may demand payment under any outstanding Letter of Credit
               supplied by the User in a sum not exceeding the available amount
               of all such Letters of Credit;

          (d)  NGC may demand payment under any outstanding Qualifying Guarantee
               provided for the benefit of the User pursuant to paragraph
               1.1.2(a).

     4.   Utilisation of Funds
          --------------------

          ln addition to the provisions of paragraph 3 above if NGC serves a
          notice of default under the terms of Clause 17.6A of a Type 1
          Supplemental Agreement and/or notice of termination under Clause 17.7
          of a Type 1 Supplemental Agreement (or the equivalent Clauses in a
          Supplemental Agreement other than a Type 1 Supplemental Agreement)
          then NGC shall be entitled to demand payment of any of the
          Transmission Services Use of System Charges which are outstanding
          whether or not the Payment Date in respect of them shall have passed
          and:-

          (i)  make demand under any outstanding Qualifying Guarantee or a call
               under any outstanding Letter of Credit supplied by the User; and

          (ii) to set off the funds in the Escrow Account to the extent that
               they represent Security Cover provided by the User against the
               Transmission Services Use of System Charges unpaid by the User
               and for that purpose NGC shall be entitled to transfer any such
               amount from the Escrow Account to any other account of NGC as it
               shall in its sole discretion think fit.


     5.   User's Right to Withdraw Funds
          ------------------------------

     5.1  If the User is not in default in respect of any amount owed to NGC in
          respect of the Transmission Services Use of System Charges under the
          terms of any Supplemental Agreement to which the User is a party:-

          5.1.1     NGC shall transfer to the User quarterly interest credited
                    to the Escrow Account; and

          5.1.2     NGC shall transfer to such User within a reasonable time
                    after such User's written request therefor any amount of
                    cash provided by the User by way of Security Cover which
                    exceeds the amount which such User is required to provide by
                    way of security in accordance with paragraph 1 of this Part

                     substituted definition  or amendment by the Landlord in

                     appropriate definition or amendment within twenty-one days

                     of the notification referred to  above then the matter

                     shall be referred for resolution to such independent

                     consultant  as the Landlord and the Tenant shall  agree or

                     (in  default of  agreement within  such twenty-one days)

                     Expert). The Expert shall act as an expert and not as an

                     arbitrator. The function of the Expert shall be to decide

                     what amendments  (if any) to this Lease are necessary in

                     order  to  reflect the commercial agreement the parties

                     Chancellor of the Exchequer ceases to be published or there

                     is a material change in the basis of the index or if at any

                     relevant time there is a delay in the publication of the

                     index the Landlord may by notice to the Tenant (i)

                     necessary to ensure that the parties are in (as far  as is

                     or amendment(s) as they were prior to the substitution or

                     amendment(s) being made. If the Tenant does not agree to

                 4   The Tenant shall as soon as reasonably practicable notify

                     the Landlord of any change to the configuration of the

                     permit it accurately to verify the calculation of the

                     Premium payable under the Eighth Schedule the matter shall

                     be  referred to such independent consultant as the Landlord

                     and the Tenant shall agree or (in default of agreement

                     within one month of the Landlord notifying the

                     applicability of this paragraph 5) such independent

                     consultant as shall be appointed at  the request of

                     the Landlord by the President of the Electricity

                     calculation of the Premium payable under the Eighth

                     Schedule.  In doing so the Data Expert shall act as an

                     expert and not  as an  arbitrator. The statement produced

                     by the Data Expert  shall be treated as an agreed

                     adjustment under paragraph 2.6 of the Eighth Schedule.

                 6   Defined  terms  in this  Ninth Schedule  not  otherwise

                   not been agreed by that review date rent shall continue to
                   be payable at the rate previously payable and forthwith upon
                   the revised rent being ascertained:


                   (a)  the Tenant shall pay to the Landlord any shortfall
                        between the rent and the revised rent payable up to and

                        a day-to-day basis from the relevant review date on
                        which it would have been payable if the revised rent
                        had then been ascertained to the date of actual payment
                        of any shortfall; and

                   (b)  the Landlord shall pay to the Tenant any excess between
                        the rent and the revised rent payable up to and on the
                        preceding quarter day together with interest in any
                        excess at the seven day deposit rate of National

                        sub-paragraph (a) of this present subclause (C)(i).

              (ii) For the purposes of this proviso the revised rent shall be
                   deemed to have been ascertained on the date when the same
                   has been agreed between the Landlord and the Tenant or as
                   the case may be the date of the award of the arbitrator.

         (D)  If either the Landlord or the Tenant shall fail to pay any costs
              awarded against it in an arbitration under the provisions hereof
              within twenty-one days of the same being demanded by the
              arbitrator the other shall be entitled to pay the name and the
              amount so paid shall be repaid by the party chargeable on demand.

         (E)  If at any time on or after the tenth anniversary of the Term the
              Demised Premises shall cease to be used for the generation of
              electricity and shall be disconnected from the sub-station (the

          this Lease and the Drakelow Lease;

          1.2  the Premium has not been, and will not be, apportioned
          between the Demised Premises and the premises comprised within
          the Drakelow Lease;

          1.3  the Premium is due in full on the date of this Lease
          Provided always that, Eastern observing and performing the
          covenants on its part and the conditions contained in this Lease,
          including those as to payment of the Premium, PowerGen will
          accept payment of the Premium in accordance with the provisions
          of clause 5 and Schedule 1 to the Agreement for Lease;

          1.4  in the event that the Termination of the Term or the
          Handover Date occurs at any time when any part or the whole of
          the Premium is outstanding for whatever reason, then the whole of
          the outstanding balance of the Premium shall immediately become
          due and payable by Eastern;

          1.5  Eastern shall not, and shall procure that no member of the
          same group of companies as Eastern shall, seek to agree that any
          part of the Premium (other than as mentioned in clause 28 of the
          Agreement for Lease) should give rise to any relief or allowance
          for tax purposes other than as consideration, falling within
          section 38(1)(a) of the Transfer of Chargeable Gains Act 1992,
          given for the acquisition of its leasehold interests in land
          under this Lease and the Drakelow Lease.

          2.   FORFEITURE

          2.   This Lease is made on the express condition that if and
          whenever there shall be a breach, non-performance or non-
          observance of the covenant contained in paragraph 17.1 of
          Schedule 3 then PowerGen or its agents may at any time thereafter
          and notwithstanding the waiver or implied waiver of any previous
          right of re-entry arising under this Lease re-enter upon the
          Demised Premises or any part thereof in the name of the whole of
          the Demised Premises whereupon the Term shall absolutely cease
          and determine but without prejudice to any rights or remedies
          which may then have accrued to PowerGen in respect of payment of
          the Premium, arrears of rent or other breach or non-performance
          or non-observance of any condition covenant or agreement on the
          part of Eastern contained in this Lease or otherwise Provided
          always that PowerGen shall, if able to do so without prejudicing
          its obligations and liabilities under the Clawback Debenture,
          give such notice as is reasonably practicable to Eastern prior to
          exercising its rights pursuant to this paragraph.

          3.   NOTICES

          3.   All notices to be given under this Lease shall be in writing
          and Section 196 of the Law of Property Act 1925 as amended by the
          Recorded Delivery Service Act 1962 shall apply to the service of
          all such notices and in case of any notice to be served on
          Eastern such notice shall also be duly served if left at the
          Demised Premises or sent to the last known address of Eastern.

          4.   L & T A COMPENSATION EXCLUSION

          4.   Subject to the provisions of sub-section (2) of Section 38
          of the Landlord and Tenant Act 1954 neither Eastern nor any
          assignee or underlessee (whether immediate or derivative) of the
          Term or of the Demised Premises shall be entitled on quitting the
          Demised Premises to any compensation under Section 37 of such Act
          or under any corresponding provisions in any Act amending or
          replacing the same.

          5.   INTEREST ON UNPAID RENTS AND OTHER MONEYS

          5.   If the Basic Rent or any other amounts payable hereunder
          shall not be paid to PowerGen within seven days of the due date

          such sums (but without prejudice to all or any other rights or
          remedies of PowerGen under this Lease) interest thereon at the
          Prescribed Rate calculated on a day-to-day basis (and compounded
          with rests on the Rent Days) from the date on which the same
          became due and payable or (if earlier) the date of expenditure by
          PowerGen down to the date of payment or reimbursement by Eastern
          (and as well after as before any judgment).

          6.   NON-ACQUISITION OF EASEMENTS

          6.   Except as expressly herein provided Eastern shall not by
          implication of law or otherwise be entitled to any estate or any
          right privilege or easement whatsoever nor shall Eastern by
          virtue or in respect of the Demised Premises or this Lease be
          deemed to have acquired or to be entitled nor shall it during the
          Term acquire or become entitled by length of enjoyment
          prescription or any other means to any such estate right
          privilege or easement.

          7.   RENT ACCEPTANCE WHEN BREACH EXISTS

          7.   No demand for or acceptance or receipt of the Basic Rent or
          any other rents or any payment on account thereof shall operate
          as a waiver by PowerGen of any right which PowerGen may have to
          forfeit this Lease or re-enter the Demised Premises by reason of
          any breach of covenant by Eastern or otherwise notwithstanding
          that PowerGen may know or be deemed to know of such at the time
          of demand, acceptance or receipt.

          8.   DISPUTES

          8.   In the event of any dispute or difference between the

          decision of such nominee shall be final and binding on the
          parties Provided that in every case the nominee appointed shall
          be entitled to act as an expert and not as an arbitrator in any
          case where he expresses his willingness so to act and neither
          party objects to him so acting within twenty-one days of his
          statement that he is willing to do so and (subject to the
          foregoing) the provisions of the Arbitration Acts 1950-1979 shall
          apply.


          9.   LIABILITY FOR INDIRECT DAMAGE

                                      SCHEDULE 8

          1.1  In this Schedule "review date" means the expiration of the
               eighth year of the Term and every fifth year thereafter and
               `review period' means the period starting with any review
               date up to the next review date or starting with the last
               review date up to the end of the said Term.

          1.2  Properties may by giving to Generation prior written notice
               elect to review of the yearly rent payable hereunder on any
               review date.  The yearly rent shall be:

               (A)  until the first review date the yearly rent of thirty-
                    one million two hundred and fifty thousand pounds
                    (pound sterling 31,250,000) payable under clause 2; and

               (B)  during each successive review period such revised rent
                    as may be ascertained as herein provided subject only
                    to the provisions of clause 1.4(E) of this Schedule.

          1.3  Such revised rent for any review period may be agreed at any
               time between the Properties and Generation or (in the
               absence of agreement) determined not earlier than the
               relevant review date by an arbitrator such arbitrator to be
               nominated in the absence of agreement by or on behalf of the
               President for the time being of the Royal Institution of
               Chartered Surveyors on the application of Properties or
               Generation made not earlier than six months before the
               relevant review date but not later than the end of the
               relevant review period and so that in the case of such
               arbitration the revised rent to be awarded by the arbitrator
               shall be such as he shall decide is the yearly rent at which
               the Demised Premises might reasonably be expected to be let
               at the relevant review date:

               (A)  On the following assumptions at that date:

                    (i)  that the Demised Premises:

                         (a)  are available to let on the open market
                              without a fine or premium with vacant
                              possession by a willing landlord to a willing
                              tenant for the residue then unexpired of the
                              term of this lease;

                         (b)  are to be let subject to the terms of this
                              Lease (other than the amount of the rent
                              hereby reserved but including the provisions
                              for review of that rent);

               (B)  But disregarding any increase in rental value of the
                    Demised Premises attributable to the existence at the
                    relevant review date of any improvement to the Demised
                    Premises or any part thereof carried out with consent
                    where required otherwise than in pursuance of an
                    obligation to Properties or its predecessors in title
                    except obligations requiring compliance with statutes
                    or directions of local authorities or other bodies
                    exercising powers under statute or Royal Charter either
                    (a) by Generation its sub-tenants or their respective
                    predecessors in title during the term or during any
                    period of occupation prior thereto arising out of an
                    agreement to grant such term or (b) by any tenant or
                    sub-tenant of the Demised Premises before the
                    commencement of the Term so long as the Properties or
                    its predecessors in title have not since the
                    improvement was carried out had vacant possession of
                    the relevant part of the Demised Premises.

          1.4  It is hereby further provided in relation to the
               ascertainment and payment of revised rent as follows:

               (A)  The arbitration shall be conducted in accordance with
                    the Arbitration Acts 1950 and 1979 or any statutory
                    modification or re-enactment thereof for the time being
                    in force with the further provision that if the
                    arbitrator nominated pursuant to sub-clause 1.3 hereof
                    shall die or decline to act as the President for the
                    time being of the Royal Institution of Chartered
                    Surveyors or the person acting on his behalf may on the
                    application of either the Properties or Generation by
                    writing discharge the arbitrator and appoint another in
                    his place.

               (B)  When the amount of any rent to be ascertained or
                    payable as herein provided shall have been so
                    ascertained or payable a memoranda thereof shall
                    thereupon be signed by or on behalf of Properties and
                    Generation and annexed to this lease and counterpart
                    thereof and the parties shall bear their own costs in
                    respect thereof.

               (C)  (i)  If the revised rent payable on and from any review
                         date has not been agreed by that review date rent
                         shall continue to be payable at the rate
                         previously payable and forthwith upon the revised
                         rent being ascertained:

                         (a)  Generation shall pay to Properties any
                              shortfall between the rent and the revised
                              rent payable up to and on the preceding
                              quarter day together with interest on any
                              shortfall at the seven-day deposit rate of

                              to be calculated on a day-to-day basis from
                              the relevant review date on which it would
                              have been payable if the revised rent had
                              then been ascertained to the date of actual
                              payment of any shortfall; and

                         (b)  Properties shall pay to Generation any excess
                              between the rent and the revised rent payable
                              up to and on the preceding quarter day
                              together with interest in any excess at the
                              seven day deposit rate of National
                              Westminster Bank PLC on the same basis as in
                              subparagraph (a) of this present sub-clause
                              (C) (i).

                    (ii) For the purposes of this proviso the revised rent
                         shall be deemed to have been ascertained on the
                         date when the same has been agreed between
                         Properties and Generation or as the case may be
                         the date of the award of the arbitrator.

               (D)  If either Properties or Generation shall fail to pay
                    any costs awarded against it in an arbitration under

                  relevant review date of any improvement to the Demised
                  Premises or any part thereof carried out with consent
                  where required otherwise than in pursuance of an

                                between the Rent and the revised Rent payable

                           award of the arbitrator.
