          Our opinion is based upon facts described in the Registration
          Statement and upon facts represented to us or determined by us as
          of the date hereof.  Our opinion is also based upon existing
          United Kingdom law, practice and judicial and administrative
          precedent, all of which are subject to change either
          prospectively or retroactively.

          Based upon the foregoing, it is our opinion that the summary of
          current law and practice in the United Kingdom relating to the
          taxation of the New Notes as set out under the heading "CERTAIN
          INCOME TAX CONSIDERATIONS" -- "UK Tax Considerations" is a summary
          of current United Kingdom tax consequences for those noteholders
          to whom that summary relates.

          We hereby consent to the use of our name in the Registration
          Statement and to the use of this opinion as an exhibit thereto.

          Yours faithfully

                                        pursuant to this Clause 1.5, if Parties'
                                        working practices current at the date on
                                        which this Clause 1.5 takes effect are
                                        inconsistent with the terms of any
                                        Agreed Procedure or Code of Practice,

                                        the Review End Date then, until it is
                                        completed, the Parties shall continue to
                                        comply with the Parties' working
                                        practices then current.

          Availability and Genset Re-Offered Availability do not exceed at any
          time the maximum Gross/Net generation which it, acting as a prudent
          operator using Good Industry Practice, would reasonably expect to
          achieve if such Centrally Despatched Generating Unit were to be
          despatched at that level. In this Clause 1.6 capitalised terms not

          3.3.1     Upon receipt of any Admission Application duly completed the

                    Parties and the Director of such receipt and of the name of
                    the New Party.

          3.3.2     Within 60 days after receipt of a duly completed Admission
                    Application from a New Party the Executive Committee shall
                    notify the New Party and the Director either:-

                    (a)       that the New Party shall be admitted as a Party,
                              in which event the provisions of Clause 3.6 shall
                              apply; or

                    (b)       that the Executive Committee requires the New

                              Executive Committee ("Additional Evidence")
                              demonstrating the New Party's fulfilment of the
                              admission conditions relevant to it set out in its
                              Admission Application, in which event the
                              provisions of Clause 3.4 shall apply.

                    If the Executive Committee shall fail so to notify the New
                    Party and the Director, the New Party may within 28 days
                    after the expiry of the said 60 day period refer the matter

          New Party shall:-

          3.4.1     provide the Executive Committee with the Additional

                    apply; or

<PAGE>


          3.4.2     refer the matter to the Director pursuant to Clause 3.5, in
                    which event the provisions of that Clause shall apply,

          failing which the New Party's application for admission shall lapse
          and be of no effect and the New Party shall not be, and shall not be
          entitled to be, admitted as a Party consequent upon such application
          (but without prejudice to any new application for admission it may
          make thereafter).

3.5       Reference to the Director:

          3.5.1     If:-

                    (a)       any dispute shall arise between the Executive
                              Committee and a New Party over whether the New
                              Party has fulfilled the admission conditions
                              relevant to it; or

                    (b)       the Executive Committee shall have failed to
                              notify the New Party as provided in Clause 3.3
                              within the 60 day period therein specified,

                    the issue of whether the New Party has fulfilled the
                    admission conditions relevant to it may be referred by way
                    of written application of the New Party, copied to the
                    Executive Committee, to the Director for determination. The
                    determination of the Director, which shall be made within 28
                    days after receipt of the said written application and shall
                    be to the effect set out in paragraph (a) or (b) of Clause
                    3.5.2, shall be final and binding for all purposes. The
                    Director shall publish reasons supporting his determination.

          3.5.2     (a)       If the determination is to the effect that the New
                              Party has fulfilled the said admission conditions,
                              the New Party shall be admitted and the provisions
                              of Clause 3.6 shall apply.

                    (b)       If the determination is to the effect that the New
                              Party has not fulfilled the said admission
                              conditions, the New Party's application for
                              admission shall lapse and be of no effect and the
                              New Party shall not be, and shall not be entitled
                              to be, admitted as a Party consequent upon such
                              application (but without prejudice to any new
                              application it may make thereafter).

3.6       Admission: If:-

          3.6.1     the Executive Committee shall notify the New Party and the
                    Director as provided in Clause 3.3.2(a); or

          3.6.2     following a request for Additional Evidence pursuant to
                    Clause 3.3.2(b), the New Party provides the same within the
                    period specified in Clause 3.4; or

          the Executive Committee shall forthwith prepare or cause to be
          prepared an Accession Agreement. Subject to the Executive Committee
          making all notifications and filings (if any) required of it for
          regulatory purposes and obtaining all regulatory consents and
          approvals (if any) required to be obtained by it, the Executive
          Committee shall instruct the Chief Executive or another person

          Accession Agreement and to sign and deliver the Accession Agreement on
          behalf of all Parties other than the New Party and the New Party shall
          also execute and deliver the Accession Agreement and, on and subject
          to the terms and conditions of the Accession Agreement, the New Party
          shall become a Party for all purposes of this Agreement with effect
          from the date specified in such Accession Agreement (and, if no such

          Party shall pay all costs and expenses associated with the
          preparation, execution and delivery of its Accession Agreement. Each

          person authorised for the purpose by the Executive Committee to sign
          on its behalf Accession Agreements and undertakes not to withdraw,
          qualify or revoke such authority and instruction at any time. The
          Executive Committee shall promptly notify all Parties and the Director
          of the execution and delivery of each Accession Agreement.

          Party, a New Party shall execute and deliver such further agreements

          The application fee shall be (pound)250 or such other amount as the
          Executive Committee may, with the prior approval of the Director, from
          time to time prescribe.

          it shall at all times satisfy or otherwise comply with the admission
          conditions set out in its Admission Application applicable to it
          (and/or such further or other conditions as the Executive Committee
          may from time to time reasonably specify) and upon request from time
          to time shall promptly provide the Executive Committee with evidence
          reasonably satisfactory to the Executive Committee of such
          satisfaction and compliance.

                    Interconnected Party and any Party admitted as an additional

                    application to the Executive Committee and satisfaction of
                    such conditions (if any) as the Executive Committee may
                    reasonably require, change the capacity(ies) in which it
                    participates as a Party.

<PAGE>


          3.10.2    If upon receipt of any Admission Application the Executive
                    Committee shall consider that the New Party should either:-

                    (a)       not be admitted as a Party in the capacity in
                              which it has applied so to be admitted but should
                              be admitted in another capacity; or

                    (b)       be admitted both in the capacity in which it has
                              applied so to be admitted and in another capacity,

                    then the Executive Committee shall within the period
                    specified in Clause 3.3.2 notify the New Party and the
                    Director accordingly and shall specify what, if any,
                    additional evidence the Executive Committee requires the New
                    Party to produce to demonstrate its fulfilment of the
                    admission conditions relevant to its admission in such other
                    capacity(ies). The provisions of Clauses 3.4, 3.5 and 3.6
                    shall apply mutatis mutandis but as if the references
                    therein to Additional Evidence were read and construed as
                    references to the said additional evidence.

          System Administrator requiring to be admitted as a Party in that
          capacity shall, upon application to the Executive Committee, be so
          admitted by way of Accession Agreement modified insofar as is
          necessary to take account of the capacity in which such successor is
          to be admitted. The provisions of Clause 3.6 shall apply mutatis
          mutandis to any such admission.

          require.

3.13      Successor Grid Operator: Any successor Grid Operator requiring to be
          admitted as a Party in that capacity shall, upon application to the
          Executive Committee, be so admitted by way of Accession Agreement
          modified insofar as is necessary to take account of the capacity in
          which such successor is to be admitted. The provisions of Clause 3.6
          shall apply mutatis mutandis to any such admission.

3.14      Successor Ancillary Services Provider: Any successor Ancillary
          Services Provider requiring to be admitted as a Party in that capacity
          shall, upon application to the Executive Committee, be so admitted by
          way of Accession Agreement modified insofar as is necessary to take
          account of the capacity in which such successor is to be admitted. The

          admission.

          with the Settlement System Administrator, the Pool Auditor and, to the
          extent that the Executive Committee considers it appropriate, the Pool
          Agents) the operation in practice of this Agreement and the Settlement
          System to assess whether the principal objects and purpose set out in
          Clause 4.1 are being or could be better achieved. In carrying out each
          such review the Executive Committee shall give due consideration to
          any matter referred to it by any Party or Pool Agent, the Pool
          Auditor, the Director or the Secretary of State. Clauses 5.5 to 5.15

          State (and, if the Executive Committee considers it appropriate, the
          Pool Agents or any one or more of them).

                    in Clause 4.1;

          5.7.5     the effect which any such recommendation referred to in
                    Clause 5.7.4 would, if implemented, have on the role of the
                    Pool Auditor under this Agreement and any comments of the
                    Pool Auditor thereon;

          any Recommendation is so approved (an "Approved Recommendation") then,
          subject to Clause 13.5, the provisions of Clauses 5.9 to 5.14
          (inclusive) shall have effect in relation thereto. If any
          Recommendation is not so approved, no further action shall be taken in
          respect thereof arising from such report.

          Pool

<PAGE>


          Members and with Pool Agents who, in either case, might reasonably be
          expected to be affected by the Works Programme) include:-

                    Principle or (as the case may be) the Approved
                    Recommendation, including (where appropriate) a series of
                    milestone and/or target dates for the achievement of
                    specified parts of such programme;

                    Recommendation is to be implemented, including a detailed
                    analysis of such New Principle or Approved Recommendation
                    and the objectives which it is intended to achieve, the work
                    involved, the resources required and the amendments likely
                    to be required to this Agreement, the Specification and to
                    any other relevant agreement or document and of any changes
                    required to be made to the Software or the Hardware; and

          (c)       an estimate of the cost of such implementation supported by
                    a breakdown of such cost and a detailed commentary on each
                    element thereof together with proposals for the recovery of
                    such cost;

          and (unless otherwise resolved by the Executive Committee after
          consultation with those Parties not being Pool Members and with Pool
          Agents who, in either case, might reasonably be expected to be
          affected by the Works Programme) shall be supported by:-

          (i)       any draft legal documentation required to give effect to the
                    amendments referred to in paragraph (b) above; and

          (ii)      the outline form of agreement appointing the Works Programme
                    Manager as project manager for the implementation of the
                    Works Programme (which form shall, where the Settlement
                    System Administrator is or, in the Executive Committee's
                    opinion, is likely to be the Works Programme Manager or
                    where the Works Programme involves changes to the
                    Specification (so far as applicable to or having an effect
                    on the Stage 1 Settlement System) or the Stage 1 Software,
                    be prepared in consultation with the Settlement System
                    Administrator).

          The provisions of this Clause 5.9 shall not apply to Settlement Goal
          or Generation Schedule Goal.

5.10      Review: The Executive Committee shall arrange for a copy of each Works
          Programme to be sent to each Party, the Pool Auditor and the Director
          and to each Pool Agent who might reasonably be expected to be affected
          by the Works Programme for review under cover of a letter setting a
          deadline for receipt of comments on such Works Programme (being no
          earlier than one month and no later than two months after the date of
          despatch of copies of the Works Programme for comment) and indicating
          to whom such comments should be addressed. Within such time as is
          reasonable after the deadline set for receipt of comments but, in any
          event, within two months thereafter, the Executive

<PAGE>


          Committee shall revise (or cause to be revised) the Works Programme to
          take into account (so far as it considers desirable) the comments
          received from the Parties, the Pool Auditor, the Director and affected
          Pool Agents.

5.11      General Meeting referral: As soon as a Works Programme has been
          revised as provided in Clause 5.10 (or, if the Executive Committee
          considers no such revision desirable, within one month after the
          deadline set under Clause 5.10 for receipt of comments on such Works
          Programme), the Executive Committee shall convene an extraordinary
          general meeting of Pool Members to consider and, if thought fit,
          approve such Works Programme (with or without amendment).

5.12      Approval of the Works Programme:

          5.12.1    A Works Programme shall not be given effect to unless and
                    until approved by the Pool Members in general meeting.
                    Additionally, if a Works Programme or any part thereof shall
                    involve a matter requiring the approval of Generators or
                    Suppliers in separate general meeting under Clause 13.2 (a
                    "Class Issue"), then such Works Programme shall not be given
                    effect to unless and until approved by the relevant class of
                    Pool Members. If a Works Programme shall not be duly
                    approved (with or without amendment), then the Executive
                    Committee shall revise (or cause to be revised) the same to
                    take account of the wishes of the Pool Members in general
                    meeting and/or (as the case may be) in separate general
                    meeting and thereafter such revised Works Programme shall be
                    re-submitted to the Pool Members in general meeting and, if
                    such revised Works Programme or any part thereof shall
                    involve a Class Issue, to the relevant Pool Members in
                    separate general meeting, in each case for approval (with or
                    without amendment). This revision and re-submission
                    procedure shall be repeated as often as may be required
                    until such time as the Pool Members in general meeting and,
                    as necessary, in separate general meetings approve the Works
                    Programme.

          5.12.2    Notwithstanding the provisions of Clause 5.12.1, the
                    Executive Committee and each Party shall be entitled at any
                    time prior to the approval of a Works Programme by the Pool
                    Members in general meeting and (where required under Clause
                    5.12.1) by the relevant class of Pool Members in separate
                    general meeting to apply to the Director requesting that the
                    implementation of the New Principle or (as the case may be)
                    the Approved Recommendation should not proceed or should not
                    proceed in the manner set out by such Works Programme and,
                    in such event, effect shall not be given to the Works
                    Programme pending the determination of the Director and then
                    (subject as provided in Clause 5.14) only to the extent (if
                    at all) that the Director in his absolute discretion shall
                    approve.

5.13      Implementation: The implementation of a Works Programme shall be
          project managed:-

          5.13.1    if the Works Programme has a significant impact on the Stage
                    1 Settlement System, by the Settlement System Administrator;
                    or

<PAGE>


          5.13.2    in any other case or if the Settlement System Administrator
                    is unable or unwilling to project manage a Works Programme
                    falling within Clause 5.13.1, by such person as the
                    Executive Committee shall nominate

          (in either case, the "Works Programme Manager") upon and subject to
          such terms and conditions as are agreed by the Executive Committee
          with the Works Programme Manager and the cost thereof recovered in
          accordance with the terms of the relevant Works Programme. Cost
          overruns, liquidated damages and all other financing costs, incentives
          and penalties shall be financed, levied and/or paid at the times and
          in the manner provided for in such Works Programme. Costs incurred by
          the Settlement System Administrator shall be recovered in accordance
          with the Charging Procedure. The Executive Committee shall require the
          Works Programme Manager to prepare and submit to the Executive
          Committee no less frequently than quarterly a written report giving a
          detailed commentary on the progress of implementing each Works
          Programme, including a comparison of actual progress made against the
          timetable set by such Works Programme and of actual costs incurred
          against budgeted costs.

5.14      Pool Auditor's approval: At the completion of the work required by
          each Works Programme but prior to effect being given to the New
          Principle or (as the case may be) the Approved Recommendation the
          Executive Committee shall request the Pool Auditor to issue an opinion
          in form and content satisfactory to the Executive Committee confirming
          to all Parties and the Director that the Pool Auditor has inspected
          and tested the arrangements giving effect to the New Principle or (as
          the case may be) the Approved Recommendation and is satisfied (without
          qualification or reservation) that such arrangements do give effect to
          the New Principle or Approved Recommendation in the manner required by
          the Works Programme. The Executive Committee shall use all reasonable
          endeavours to make (or procure to be made) such modifications to such
          arrangements as are necessary to enable the Pool Auditor to give its
          opinion without qualification or reservation, and the costs of any
          such modification shall be recovered in accordance with the relevant
          Works Programme. If the Pool Auditor's opinion can be given only with
          qualification or reservation, the Executive Committee shall convene an
          extraordinary general meeting of Pool Members and, where required
          under Clause 5.12.1, a separate general meeting of Generators and/or
          (as the case may be) Suppliers to consider and, if thought fit,
          approve such arrangements in the knowledge that the Pool Auditor's
          opinion can be given only with qualification or reservation. Subject
          to the provisions of Clause 6, each of the Parties undertakes with
          each of the other Parties promptly following the issue of the Pool
          Auditor's opinion (but, where such opinion has a qualification or
          reservation, only after approval as aforesaid by the Pool Members in
          general meeting and, where required under Clause 5.12.1, by the
          relevant class of Pool Members in separate general meeting) to execute
          and deliver any amending agreement or other documents and to take such
          other action as may reasonably be required of it to give effect to
          such arrangements, in any such case at its own cost and expense.

<PAGE>


5.15      Secretary of State's approval: In respect of the Secretary of State's
          decision as set out in his letter of 11th December, 1991 to the Chief
          Executive concerning the selling of the output of plant by Generators
          with on-site demand under this Agreement:-

          5.15.1    each of the Parties undertakes with each of the other
                    Parties forthwith to take all such steps (including as to
                    the execution of any document) as may be required to give
                    full force and effect to the decision of the Secretary of
                    State. Each of the Parties shall take all such steps at its
                    own cost and expense except that the Settlement System
                    Administrator, the Pool Funds Administrator and the
                    Ancillary Services Provider shall be entitled to recover any
                    such costs and expenses in accordance with the terms of this
                    Agreement; and

          5.15.2    each of the Parties acknowledges and agrees that damages
                    would not be an adequate remedy for any failure by it to
                    give in accordance with Clause 5.15.1 full force and effect
                    to the decision of the Secretary of State pursuant to this
                    Clause 5.15 and that, accordingly, each of the other Parties
                    and the Director shall be entitled to the remedies of
                    injunction, specific performance and other equitable relief
                    for any threatened or actual such failure and that no proof
                    of special damages shall be necessary for enforcement.

5.16      Director's modifications:

          5.16.1    Where the Monopolies and Mergers Commission has issued a
                    report on a reference under section 12 of the Act which:-

                    (a)       includes conclusions to the effect that any of the
                              matters specified in the reference operate, or may
                              be expected to operate, against the public
                              interest;

                    (b)       specifies effects adverse to the public interest
                              which those matters have or may be expected to
                              have;

                    (c)       includes conclusions to the effect that those
                              effects could be remedied or prevented by
                              modifications of the conditions of any Licence and
                              such modifications would require a change to the
                              Pooling and Settlement Agreement; and

                    (d)       specifies modifications by which those effects
                              could be remedied or prevented,

                    the Director may, subject to the following provisions of
                    this Clause, require such modifications to this Agreement as
                    are requisite for the purpose of remedying or preventing the
                    adverse effect specified in the report.

          5.16.2    Before requiring modifications to be made pursuant to this
                    Clause, the Director shall have regard to the modifications
                    specified in the report. Further, the

<PAGE>


                    Director shall not, and shall not be entitled to, require a
                    modification to be made to this Agreement which modification
                    could not have been achieved lawfully through a modification
                    of one or more Licences consequent upon the report (but as
                    if, for this purpose, only those Parties who are holders of
                    Licences were parties to this Agreement).

          5.16.3    Before requiring modifications to be made pursuant to this
                    Clause, the Director shall give notice:-

                    (a)       stating that he proposes to make the modifications
                              and setting out their effect;

                    (b)       stating the reasons why he proposes to make the
                              modifications; and

                    (c)       specifying the period (not being less than 28 days

          inconsistency or conflict:-

          6.8.1     the Pool Rules (excluding sub-section 8.4.3 and the Datum
                    Document) shall prevail over the other provisions of this
                    Agreement (except Clause 4);

          6.8.2     the provisions of this Agreement shall prevail over the
                    Specification;

          6.8.3     the Specification shall prevail over the Software;

          6.8.4     the provisions of this Agreement shall prevail over the
                    provisions of an Agreed Procedure, a Code of Practice, a
                    Service Line, the Development Policies or the Change
                    Management Policies; and

<PAGE>


          6.8.5     the provisions of a Service Line shall prevail over the
                    provisions of an Agreed Procedure or a Code of Practice,

          and the Parties shall use all reasonable endeavours promptly to secure
          the elimination of such inconsistency or conflict.

6.9       Conflicts with the Grid Code:

          6.9.1     Each of the Parties hereby acknowledges and agrees the
                    desirability of achieving and maintaining consistency and
                    absence of conflict between the provisions of this Agreement
                    and the Grid Code but recognises that, due principally to
                    the different functions and objectives of this Agreement and
                    the Grid Code, the fact that there may be Parties who are
                    not bound by the Grid Code and the different procedures in
                    this Agreement and the Grid Code for review of their
                    respective terms, it will not in all circumstances be
                    possible to avoid inconsistency or conflict.

          6.9.2     Where at the Effective Date there is an inconsistency or
                    conflict between the provisions of this Agreement and the
                    Grid Code the Executive Committee shall first consider the
                    matter and make recommendations and thereafter the Parties
                    shall negotiate in good faith to eliminate such
                    inconsistency and/or conflict having regard to the different
                    functions and objectives of the Grid Code and this
                    Agreement.

          6.9.3     Each of the Parties shall use its reasonable endeavours to
                    ensure that where any change to this Agreement is proposed
                    to be made which may reasonably be expected to require a
                    change to the Grid Code (or vice versa) such change is
                    brought by the Executive Committee to the attention of the
                    Grid Code Review Panel in good time to enable it to consider
                    what corresponding change, if any, should be made to the
                    Grid Code or (as the case may be) this Agreement. In any
                    such consideration, the Parties acknowledge and agree that
                    it would be desirable in the event of any inconsistency or
                    conflict between the provisions of this Agreement and the
                    Grid Code if regard were had by the Grid Code Review Panel
                    to the principles set out in Clause 6.9.4.

          6.9.4     The principles referred to in Clause 6.9.3 are that:-

                    (a)       where by reason of any inconsistency or conflict
                              the security, quality of supply and/or safe
                              operation of the NGC Transmission System under
                              both normal and/or abnormal operating conditions
                              would necessarily be compromised and/or the Grid
                              Operator would necessarily be in breach of its
                              obligations under the Act or its Transmission
                              Licence, the provisions of this Agreement should
                              be made to conform (to the extent of such
                              inconsistency or conflict) to those of the Grid
                              Code; and

<PAGE>


                    (b)       in any other case, where by reason of such
                              inconsistency or conflict there is or is likely to
                              be a material financial effect on any class of
                              Pool Members or on all or a significant number of
                              Pool Members, the provisions of the Grid Code
                              should be made to conform (to the extent of such
                              inconsistency or conflict) to those of this
                              Agreement.

          6.9.5     The Parties acknowledge that changes to the Grid Code are
                    required to be approved by the Director.

          6.9.6     Where there is any conflict or inconsistency between the
                    Grid Code and the Pool Rules, no Party shall be liable
                    hereunder or under the Grid Code as a result of complying
                    with its obligations under this Agreement or under the Grid
                    Code.

6.10      Breaches of the Pool Rules: If at any time any Party believes that
          there has been a breach of the Pool Rules, such Party shall promptly
          report the same in writing to the Executive Committee.

6.11      Director's requests: The Executive Committee shall:-

          (i)       give due and prompt consideration to any matter referred to
                    it in writing by the Director;

          (ii)      advise the Director in writing of any decision or action of
                    the Executive Committee in relation to such matter;

          (iii)     provide the Director in writing with an explanation in
                    reasonable detail of the reasons for such decision or
                    action; and

          (iv)      if reasonably requested by the Director (having regard, in
                    particular, to the resources available to the Executive
                    Committee), in relation to any proposal by the Director for
                    a change to any provision of this Agreement provide or
                    procure the provision of advice and assistance to the
                    Director as soon as reasonably practicable as to the
                    implications of the change and the actions necessary to
                    implement it (including any relevant feasibility study).

6.12      Conflicts with the MRA: The provisions of Section 5 of Schedule 32
          shall have effect in relation to any conflict between this Agreement
          and the Master Registration Agreement.

                    failure of any Pool Member to carry out all or any of its
                    obligations under this Agreement shall not relieve any other

                    being held liable by operation of law (or contesting any
                    such liability) for the performance or non-performance of

          Agreement (other than (i) Metered Data and (ii) pursuant to paragraph
          2.5.2 of Schedule 9), the relevant Pool Member or (as the case may be)

                                        such Metering System properly to be
                                        taken into account for the purposes of
                                        Settlement; and

                              (ii)      without prejudice to the generality of
                                        paragraph (i), such Metering System
                                        conforms with the requirements of Part
                                        XV or (as the case may be) Schedule 28

                    (c)       the Party has entered into and has in full force
                              and effect (save for satisfaction of any condition

          capacity(ies) in which it participates as a Pool Member and any Pool
          Member who acquires an additional capacity in which it participates as
          a Pool Member shall be deemed to have been admitted as a new Pool
          Member pursuant to Clause 8.2 in that additional capacity.

                    (a)       by the Secretary on the instructions of the

                              Committee Members pursuant to Clause 13.4; or

                              of Pool Members holding together at the date of
                              the deposit of the requisition not less than two

                              Chairman.

          9.4.3     A Pool Members' requisition shall state the objects of the
                    meeting and must be signed by or on behalf of the

                    Secretary, and may consist of several documents in like form
                    each signed by one or more requisitionists. If the Executive
                    Committee does not within 21 days from the date of the
                    deposit of the requisition proceed duly to convene an
                    extraordinary general meeting for a date not later than two
                    months after the said date of deposit, the requisitionists
                    may themselves convene a meeting, but any meeting so
                    convened shall not be held after the expiration of three
                    months from such date. A meeting convened under this Clause
                    9.4 by requisitionists shall be convened in the same manner,
                    as nearly as possible, as that in which meetings are to be

          Parties, all Committee Members, the Pool Chairman, the Chief Executive
          (if any), the Pool Auditor and the Director. The accidental omission
          to give notice of a meeting to, or the non-receipt of notice of a
          meeting by, any person entitled to receive notice shall not invalidate

<PAGE>


          the proceedings at that meeting. In every such notice there shall
          appear with reasonable prominence a statement that a Pool Member
          entitled to attend and vote is entitled to appoint a proxy to attend,
          speak and (subject to Clause 12.1) vote in its place and that a proxy
          need not also be a Pool Member.

                    after the immediately preceding annual general meeting and
                    ending on the day falling one calendar month before the date
                    for which the Annual Conference has been convened. In
                    addition, the Executive Committee shall arrange for such
                    other matters to be discussed, presentations to be made and
                    Pool Member activities to be organised at the Annual
                    Conference as it may resolve to be appropriate.

                    (ii)      any recommendation which the Pool Auditor wishes
                              to make regarding the operation of the Settlement
                              System, the Charging Procedure, the PFA Accounting
                              Procedure, the ASP Accounting Procedure and/or the

                              Pool Auditor shall consider appropriate.

          9.7.3     If the Executive Committee so resolves, the Secretary shall
                    convene a meeting of all Pool Members in order to discuss
                    the Pool Auditor's Report.

                              Stage 2 Initial Settlement Run and with the number
                              of GWh being rounded up or down (0.5 being rounded
                              upwards) to the nearest whole number;

                    GWV       is the total number of Generator Weighted Votes of
                              all Pool Members for such month; and

                    (SIGMA)   means summed over the total SV of all Pool Members
                              for such month,

                    provided that the total number of Supplier Weighted Votes
                    shall at all times equal the total number of Generator
                    Weighted Votes and if, as a result of the foregoing, such
                    would not be the case, the Pool Member with the greatest
                    number of Generator Weighted Votes or of Supplier Weighted
                    Votes calculated as aforesaid shall have deducted that
                    number of Weighted Votes of the relevant class as will
                    ensure that the total number of Supplier Weighted Votes
                    equals the total number of Generator Weighted Votes.

                    For the purposes of this Clause 11.2:-

                    (a)       a Generating Unit shall be an Allocated Generating
                              Unit of a Pool Member (in this Clause, the
                              "Identified Pool Member") if it belongs to the
                              Identified Pool Member as of the date on which the
                              Executive Committee calculates the Weighted Votes
                              of Pool Members for the relevant month pursuant to
                              Clause 11.3.2. If at any time during such month an
                              Allocated Generating Unit shall belong to another
                              Pool Member (in this Clause, the "Transferee Pool
                              Member"), the Weighted Votes attributed to the
                              Identified Pool Member for such month by reason of
                              the Allocated Generating Unit belonging to it
                              shall (subject to Clause 11.4) be transferred to
                              the Transferee Pool Member as of the date on which
                              such Allocated Generating Unit first belongs to
                              the Transferee Pool Member (and the Identified
                              Pool Member and the Transferee Pool Member shall
                              jointly notify the Executive Committee in writing
                              of such date in good time before its occurrence);

                    (b)       a Generating Unit shall belong to a Pool Member if
                              it is owned by that Pool Member and not leased to
                              another person or if it is leased by that Pool
                              Member from another person;

                    (c)       a Pool Member shall notify the Executive Committee
                              promptly on request of its Allocated Generating
                              Units and the Executive Committee and each other
                              Party may rely on the information in that
                              notification and in any notification under
                              paragraph (a) above without further enquiry or
                              need to verify that information;

                    (d)       in determining the meaning of "good time" for the
                              purposes of paragraph (a) above one factor to be
                              taken into account is that the Settlement System
                              Administrator must be allowed sufficient time to
                              effect the necessary changes in Settlement
                              associated with the transfer of the relevant
                              Allocated Generating Unit; and

                    (e)       the Executive Committee may, upon application of
                              any Pool Member involved in any transfer of assets
                              between Pool Members during any month, adjust as
                              between the Pool Members involved in such
                              transfer, the number of Weighted Votes to which
                              they in their capacities as Suppliers are entitled
                              in respect of the remaining part of that month
                              and/or one or more succeeding months if, in the
                              opinion of the Executive Committee, such
                              adjustment would help accommodate the consequences
                              of such a transfer and not prejudice the interests
                              of any other Pool Member in any material respect.

                    effected in the case of votes amounting to fractions of

                    Genset Metered Generation for the relevant month or, in the
                    case of Supplier Weighted Votes, to the largest Supplier in
                    terms of Aggregate Demand for the relevant month, to the
                    extent that this does not cause a breach of Clause 11.4.1 or
                    Clause 11.4.2. Thereafter, any unallocated Fractional
                    Redistributed Votes shall be allocated in accordance with
                    this Clause 11.4.8 to the next such largest Generator and/or
                    Supplier and the process shall continue until all Fractional
                    Redistributed Votes have been so allocated.

                    (i)       the interests of a group of Pool Members
                              (including the Dissentient Pool Member) or of the
                              Dissentient Pool Member under this Agreement have
                              been, are or will be unfairly prejudiced by the
                              passing of or the failure to pass such resolution;
                              or

                    (ii)      such resolution will breach, or will cause the
                              Dissentient Pool Member to be in breach of, one or
                              more provisions of this Agreement or of its
                              Licence or of the Act.

                    Any such application shall give detailed reasons and
                    evidence in support and shall be copied to the Executive
                    Committee. The Dissentient Pool Member shall be entitled to
                    mark all or any part of such application as confidential and
                    the Executive Committee shall give such weight as it sees
                    fit to such marking in the copying of such application to
                    those persons to whom it is obliged to copy such
                    application. The Executive Committee shall promptly notify
                    all other Pool Members, each Externally Interconnected Party
                    (not being a Pool Member), the Pool Chairman, the Settlement

                    (and may send any Pool Agent) a copy of the relevant
                    application (amended, if appropriate, to take account of any
                    such marking where the Executive Committee shall have seen
                    fit so to do). The Executive Committee, each Pool Member,
                    each Externally Interconnected Party (not being a Pool
                    Member), the Pool Chairman, the Settlement System
                    Administrator and the Pool Funds Administrator and (if
                    invited by the Director) the Pool Auditor shall each be
                    entitled to make representations to the Director. If the
                    Pool Auditor shall be so invited to make any such
                    representations, the Executive Committee will provide it
                    with a copy of the relevant application (amended, if
                    appropriate, as aforesaid).

          13.5.2    Any determination of the Director in respect of any such
                    application as is referred to in Clause 13.5.1 shall be
                    final and binding. Pending any determination of the Director
                    in respect of any such application, the relevant resolution
                    (if passed) shall not have effect provided that, if the
                    Director shall decline to accept a reference or to make a
                    determination (in either case, for whatsoever reason), such
                    resolution shall take effect from the date that the Director
                    notifies the Executive Committee that he declines to accept
                    the reference or to make the determination.

          13.5.3    The Parties acknowledge and agree that the satisfaction of
                    either of the grounds referred to in Clause 13.5.1(i) or
                    (ii) shall not of itself entitle the Dissentient Pool Member
                    to a determination by the Director in its favour.

15.6      RS Committee Member election procedures: The procedures set out in
          this Clause 15.6 shall apply to the election of the RS Committee
          Members:-

          15.6.1    each RS Pool Member shall be entitled, by notice to the
                    Executive Committee given no earlier than 90 days and no
                    later than 30 days before each annual general meeting of
                    Pool Members or, failing election of either RS Committee
                    Member at such meeting, no later than 15 days before an
                    extraordinary general meeting convened for such purpose to
                    propose one individual (a "RS Nominee") to be a RS Committee
                    Member. The RS Nominee need not be an officer or employee of
                    a Pool Member but shall not be the Chief Executive or Pool
                    Chairman or any then current nominee for the position of
                    Chief Executive or Pool Chairman. Any such proposal to be
                    valid shall be accompanied by a written statement from the
                    RS Nominee stating that he is aware of the proposal and
                    would be prepared to serve as a Committee Member if elected
                    and identifying whether he is standing for the position of

                    Executive Committee shall circulate (or cause to be
                    circulated) to all Pool Members and the Director a list of
                    all the names of the RS Nominees and of the Pool Members who
                    nominated them (the "RS Nominee List"). The Director may

                    Committee no later than 5 working days before the annual
                    general meeting on the grounds that such RS Nominee could
                    not reasonably be expected to represent the interests of
                    Small Generators or (as the case may be) Independent
                    Suppliers on the Executive Committee. Any RS Nominee to whom
                    the Director so objects shall not be eligible for election
                    at the relevant meeting of Pool Members as an RS Committee
                    Member and his name shall be deleted from the RS Nominee
                    List. The RS Nominee List (amended, if necessary, to take
                    account of the Director's objections) shall be circulated at
                    the annual general meeting or, as the case may be,
                    extraordinary general meeting to all Pool Members present in
                    person and (if practicable) to all Pool Members in advance
                    of such meeting;

          15.6.3    if there is no RS Nominee or no RS Nominee eligible for
                    election as the SG Committee Member or (as the case may be)
                    the IS Committee Member, the Director shall be entitled to
                    appoint and remove an individual to serve in that capacity
                    for the term of office referred to in Clause 15.4 and the
                    procedures in Clause 15.6.4 shall not apply to the election
                    of such RS Nominee;

                              shall terminate;

                    (k)       if the condition in paragraph (j) above is not
                              satisfied, the RS Nominee whose name appears last
                              on the SG Preference List or (as the case may be)
                              IS Preference List shall be removed from that list
                              and shall take no further part in the election
                              process for the relevant RS Committee Members and
                              the Moderator shall transfer the Weighted Votes of
                              all those RS Pool Members who voted for that RS

                              respective second preference. The Moderator shall
                              then prepare a revised SG Preference List or (as
                              the case may be) IS Preference List in each case
                              to which paragraph (j) above shall be applied and
                              the procedure set out in this paragraph (k) shall

                              relation to the relevant list (on each occasion

                              respective preference); and

                    (l)       if (where applicable, after the provisions of
                              paragraph (k) above have been followed) only two

                              Member shall be decided by the drawing of lots in
                              a manner to be determined by the Pool Chairman;
                              and

          15.6.5    if a SG Pool Member is a member of a Pool Member's Group of
                    which an IS Pool Member is also a member (or vice versa) and
                    there are no MP Pool Members in that Pool Member's Group,
                    the SG Pool Member and the IS Pool Member shall jointly
                    notify the Secretary upon receipt of the RS Nominee List at
                    the annual general meeting or, as the case may be,
                    extraordinary general meeting whether the SG Pool Member
                    will participate in the election of the SG Committee Member
                    or the IS Pool Member will participate in the election of
                    the IS Committee Member. In the former case, the IS Pool
                    Member shall not have the right to participate in the
                    election of either RS Nominee and, in the latter case, the
                    SG Pool Member shall not have the right to participate in
                    the election of either RS Nominee. If no such notification
                    is received by the Secretary before the election procedure
                    for the RS Nominees begins, the votes of both the SG Pool
                    Member and the IS Pool Member shall be discounted and
                    ignored.

15.7      Spoilt papers: If any Voting Paper is incorrectly completed or
          otherwise spoilt, the Moderator shall take no account of it or of the
          Weighted Votes purported to be cast by it in the conduct of the
          procedures set out in Clause 15.5 and/or 15.6.

15.8      Default appointment: If the procedures set out in Clause 15.5 or 15.6
          (other than Clause 15.6.3) shall result in less than the prescribed or
          (as the case may be) agreed maximum number of Committee Members
          permitted under Clause 15.1 being appointed (including where there are
          insufficient nominees nominated to fill the seats), the Director shall
          have the right to appoint and remove individuals to the Executive
          Committee as Committee Members in such numbers as may be necessary to
          provide for such maximum number of Committee Members until such time
          as another election pursuant to Clause 15.5.3 or (as the case may be)
          15.6.4 takes place. Any Committee Member appointed pursuant to this
          Clause 15.8 shall, for the purposes of Clause 23.6, represent the
          interests of all Pool Members for the time being and from time to
          time.

15.9      Notification of Committee Members: The Secretary shall promptly notify
          all Pool Members and the Director of the appointment and removal of
          any Committee Member.

          15.10.1   A Committee Member may be removed by vote of all those Pool
                    Members whose Weighted Votes were cast in favour of that
                    Committee Member in his election pursuant to Clause 15.5 or
                    Clause 15.6, such vote to be passed requiring a majority of
                    65 per cent. of the total number of Weighted Votes of all
                    such Pool Members (after deduction of any Weighted Votes of
                    persons who were Pool Members at the time of his election
                    and who voted in favour of him but who are no longer Pool
                    Members). For the purposes of such vote, relevant Pool
                    Members may cast only that number of Weighted Votes which
                    they cast in favour of such Committee Member in his election
                    pursuant to Clause 15.5 or 15.6.

                    Member and to every such separate general meeting the
                    provisions of Part III relating to general meetings of Pool
                    Members (other than Clause 10.9, save in respect of the
                    attendance by the Pool Auditor or the Director or its or his
                    duly appointed representative) shall apply mutatis mutandis
                    but so that:-

                    (a)       the necessary quorum shall be one Pool Member
                              entitled to vote thereat; and

                    (b)       notice of any such separate general meeting need
                              be given only to those entitled to attend the
                              same.

15.11     Vacation of office by Committee Members: The office of a Committee
          Member shall be vacated if:-

          15.11.1   he resigns his office by notice delivered to the Secretary;

          15.11.2   he becomes bankrupt or compounds with his creditors
                    generally; or

          15.11.3   he becomes of unsound mind or a patient for any purpose of
                    any statute relating to mental health; or

          15.11.4   he and his alternate fail to attend more than three
                    consecutive meetings of the Executive Committee; or

          15.11.5   he dies; or

          15.11.6   he is removed from office pursuant to Clause 15.10.

15.12     Election of replacement Committee Members: At the time of the vacation
          of office of a Committee Member (for the purposes of this Clause 15.12
          an "Outgoing Committee Member") or as soon as is reasonably
          practicable thereafter , a replacement Committee Member shall be
          elected following the procedures set out in, in the case of an MP
          Committee Member, Clause 15.5 or, in the case of an RS Committee
          Member, Clause 15.6, provided that:-

          (a)       only Pool Members whose Weighted Votes were cast in favour

                    vacation of office, represented by him pursuant to Clause
                    23.6.1 or 23.6.2; and

<PAGE>


          (b)       only those persons who have become Pool Members in the
                    period of the Outgoing Committee Member's term of office and

          pursuant to this Clause 15.12.

15.13     Alternates:

          15.13.1   Each Committee Member shall have the power to appoint any
                    person (who may be an existing Committee Member) to be his
                    alternate and may at his discretion remove an alternate
                    Committee Member so appointed. Any appointment or removal of
                    an alternate Committee Member shall be effected by notice in
                    writing executed by the appointor and delivered to the
                    Secretary who shall forthwith notify all other Committee
                    Members of such appointment. If his appointor so requests,
                    an alternate Committee Member shall be entitled to receive
                    notice of all meetings of the Executive Committee or of
                    sub-committees or sub-groups of which his appointor is a
                    member and to receive a voting paper on a poll instead of
                    the appointor. He shall also be entitled to attend, speak
                    and vote as a Committee Member at any such meeting at which
                    the Committee Member appointing him is not personally
                    present and at the meeting to exercise and discharge all the
                    functions, powers and duties of his appointor as a Committee
                    Member and for the purposes of the proceedings at the
                    meeting the provisions of this Part IV shall apply as if he
                    were a Committee Member. He shall also be entitled to demand
                    a poll (whether at or after the meeting) pursuant to Clause
                    22.3, to carry out consultations with Pool Members
                    contemplated by Clause 22.8 insofar as his appointor shall
                    be unable to do so, to act on the instructions of Pool
                    Members duly given to his appointor or to him on behalf of
                    his appointor and to complete his appointor's voting paper
                    on a poll on behalf of his appointor.

          15.13.2   Except on a poll, every person acting as an alternate
                    Committee Member shall have one vote for each Committee
                    Member for whom he acts as alternate, in addition to his own
                    vote if he is also a Committee Member. On a poll, an
                    alternate Committee Member shall be entitled (if his
                    appointor is unable to do so) to exercise (on behalf of his
                    appointor and by completion of the appointor's separate
                    voting paper) all of the votes which his appointor is
                    entitled to cast, in addition to any votes which the
                    alternate is entitled to cast in his own capacity if he is
                    also a Committee Member. Execution by an alternate Committee
                    Member of any resolution in writing of the Executive
                    Committee shall, unless the notice of his appointment
                    provides to the contrary, be as effective as execution by
                    his appointor.

          15.13.3   An alternate Committee Member shall ipso facto cease to be
                    an alternate Committee Member if his appointor ceases for
                    any reason to be a Committee Member.

          15.13.4   References in this Agreement to a Committee Member shall,
                    unless the context otherwise requires, include his duly
                    appointed alternate.

                    (ii)      should the Executive Committee so decide, by a
                              postal vote in accordance with Clause 16.4, such
                              postal vote to have a closing date which (where
                              practicable) is not less than three months before
                              the end of the term of the then current Pool

                              the meeting at which he is elected is held after

                    (iii)     his term of office shall expire before 31st March
                              if he resigns or is unable for whatever reason to
                              continue to act or if a successor Pool Chairman is
                              elected with a term of office which Pool Members
                              either in general meeting or (as the case may be)

                    removal (subject to Clause 13.1.2)) as have been approved by
                    Pool Members in general meeting. Any amendment to those
                    terms and conditions shall require the prior approval of

                    resolve to extend the term of office of the Pool Chairman by
                    one year. If the resolution is approved in accordance with
                    the terms of this Agreement then his term of office shall be
                    so extended provided that no person shall hold office as
                    Pool Chairman for more than six consecutive years.

                    or so advised shall be discussed or resolved upon at such
                    meeting. The accidental omission to give notice of a meeting
                    or accompanying agenda or supporting documents or papers to,

                    agenda or supporting documents or papers by, any person
                    entitled to receive notice shall not invalidate the
                    proceedings at that meeting.

                    retrospectively with the consent in writing of all such
                    persons as are entitled to attend the relevant meeting.

          18.1.6    The Secretary shall prepare minutes of all meetings of the

                    such persons as were entitled to attend the relevant meeting
                    as soon as practicable (and in any event within ten working
                    days) after the relevant meeting has been held. Each person
                    who attended such meeting shall notify his approval or
                    disapproval of the minutes thereof to the Secretary no later

                    meetings of the Executive Committee to any other Party
                    within a reasonable time after request therefor provided
                    that the said time for approving or disapproving the same
                    has expired. Further, the Secretary shall provide copies of
                    such minutes to such persons as the Executive Committee may
                    from time to time direct within a reasonable time after
                    receipt of such direction.

                    appropriate in any particular case) invite any Pool Agent or
                    the Certification Agent to attend all or any part of a
                    meeting of the Executive Committee at which a matter is to
                    be considered which concerns directly the functions, duties
                    or responsibilities of that Pool Agent or (as the case may
                    be) the Certification Agent.

                    Clause 4.1.2 and to promote, and not obstruct, the fair and
                    efficient operation of the procedures referred to in Clause
                    4.1.3 so that the objectives set out in Clause 4.1.3 are
                    thereby achieved; and

          20.1.3    shall be given written terms of reference and, unless
                    otherwise varied by the Executive Committee, the provisions
                    of Clauses 18 and 19 shall apply mutatis mutandis to
                    meetings of such sub-committee and the provisions of Clauses
                    19.4, 23.3.1, 23.3.2 and 23.3.3 shall apply mutatis mutandis
                    in relation to any such sub-committee and the members

                    written terms of reference and, unless otherwise varied by
                    the Executive Committee or any sub-committee acting on the

                    Clauses 18 and 19 shall apply mutatis mutandis to meetings
                    of such sub-groups and the provisions of Clauses 23.3.1,
                    23.3.2, and 23.3.3 shall apply mutatis mutandis in relation
                    to each such sub-group and the members thereof.

          provided that a Pool Member shall not be required in any period of 12
          months to make available nominees for more than 60 days in aggregate.
          Save as provided by Clause 23.5 no payment shall be made to Pool
          Members in respect of any such attendance or participation.

          delegate all or any of its rights, powers, duties and responsibilities
          under this Agreement to the Chief Executive upon such terms and
          conditions as the Executive Committee thinks fit.

20.5      Effect of decisions: Resolutions of sub-committees shall not have
          binding effect (a) unless and then only to the extent that the
          Executive Committee shall have delegated the relevant decision-making
          powers to the sub-committee, or (b) unless approved by resolution of
          the Executive Committee (and then subject to Clause 13). Meetings of
          such sub-committees shall, so far as possible, be arranged so that
          minutes of such meetings can be circulated to each Committee Member in
          sufficient time for consideration before the next following regular
          meeting of the Executive Committee. Resolutions of sub-groups shall

          review or consultation and the preparation and submission of any
          report required of it under this Agreement, to such person or persons
          as it thinks fit and on such terms and conditions as it thinks fit and
          shall require that, in the performance of the delegated duties, such
          person or persons shall conform to any regulations that may be imposed
          on it or them by the Executive Committee.

          22.3.1    at the meeting at which the simple majority vote takes
                    place, by the chairman of the meeting or by any Committee
                    Member; or

22.4      Effect of decision: A decision duly made at a meeting of the Executive
          Committee shall (unless otherwise determined by the Executive
          Committee or otherwise provided by the terms of the decision) have
          immediate effect, unless a poll be duly demanded in accordance with

          demand for, or the remittance of a matter for decision on, a poll
          despatch to each Committee Member a voting paper in such form as shall
          be agreed by the chairman of the Executive Committee meeting at which
          the matter in question was considered or (failing him) the Chief
          Executive but which shall in any event set out the full text of the
          resolution in respect of which the poll is required (which shall be
          the same as the resolution which was put to a simple majority vote),
          shall provide for each Committee Member to cast votes for or against
          the resolution and shall specify the date by which votes must be
          lodged by Committee Members. The Secretary shall at the same time give
          notice to all Parties that a poll has been demanded and shall specify
          in such notice the resolution on which the poll has been called (if
          applicable), the identity of the person (or persons) who has demanded
          the poll and the date by which votes must be lodged by the Committee

          notice by, any person entitled to receive the voting paper or (as the
          case may be) the notice shall not invalidate the conduct of the poll
          or the result thereof.

          22.7.1    the Committee Members shall in aggregate be entitled to a
                    number of votes equal to the number of votes which the Pool

                    general meeting if such meeting had taken place on the day

                    his Constituents and shall cast such votes in accordance
                    with the individual written instructions of each such
                    Constituent, but so that no Constituent shall be entitled to
                    instruct that the votes attributable to it be cast more than
                    once;

          22.7.3    in the absence of any written instructions from any
                    Constituent, a Committee Member shall not be entitled to

                    abstain from casting any or a specified number of votes on
                    its behalf;

                    unless:-

                    (a)       the relevant voting paper shall have been received
                              by the Secretary on or before the date falling 10
                              working days after the date on which the voting
                              papers were despatched to Committee Members and
                              the votes cast in such voting paper accord with
                              the written instructions referred to in paragraph
                              (b) below;

                    (b)       accompanied by a copy of the written instructions

                              and

                    (c)       the Committee Member in other respects shall have
                              complied with the procedures for votes on a poll
                              (if any) from time to time established by the
                              Executive Committee; and

          22.7.6    any Constituent on whose instructions a Committee Member is
                    required to act in accordance with the foregoing provisions
                    shall be entitled to make arrangements with any other
                    Constituent on whose instructions that same Committee Member
                    is required to act for the requisite written instructions to
                    be given on its behalf by that other Constituent. Details of
                    any such arrangement shall promptly be given to the

                    Agreed Procedures, the Pool Funds Administrator shall permit
                    the Pool Auditor unrestricted access to its operation of the

                    in the conduct of such business and shall make available
                    members of its staff to explain such operations and such
                    other issues as the auditor considers relevant.

          48.4.4    Without prejudice to specific rights of access granted
                    elsewhere to the Pool Auditor, each of the Parties shall use
                    its reasonable endeavours to procure for the Pool Auditor
                    access to premises, personnel, data, information and records
                    sufficient to enable the Pool Auditor properly to perform

                    or the Chief Executive, the Grid Operator shall have no

                    directions, instructions, approval or consent have first
                    been obtained. Notwithstanding the foregoing sentence,
                    nothing in this Agreement shall prevent the Executive

                    bound to act in accordance with the directions or

          50.2.6    General Meetings: The Grid Operator shall not be obliged to
                    take any steps to ascertain whether any resolution of Pool
                    Members in general meeting or of any class of Pool Members
                    in separate general meeting which it is advised by the
                    Executive Committee or the Chief Executive as having been
                    passed was in fact

<PAGE>


                    passed or passed by the requisite majority and until the
                    Grid Operator shall have express written notice to the
                    contrary from the Executive Committee or the Chief Executive
                    it shall be entitled to assume that the relevant resolution
                    was passed or (as the case may be) the relevant requisite
                    majority was obtained.

          50.2.7    Exceptions: Notwithstanding the foregoing provisions of this
                    Clause 50.2, in the performance of its duties and
                    responsibilities under this Agreement the Grid Operator
                    shall not be bound to act in accordance with the directions
                    or instructions of the Executive Committee or the Chief
                    Executive:-

                    (a)       if to do so would cause the Grid Operator to
                              breach any of its obligations under the Act or its
                              Transmission Licence; or

                    (b)       if the Grid Operator has reasonable grounds for
                              believing that it would so breach any of such
                              obligations and has consulted the Director and the
                              Director has not indicated that in his view it
                              would not involve any such breach; or

                    (c)       unless the Director has indicated that,
                              notwithstanding any such actual or potential
                              breach, the Director would not be minded to
                              enforce compliance with those obligations under
                              the Act or its Transmission Licence and the Grid
                              Operator has received an indemnity reasonably
                              satisfactory to it in respect of its acting in
                              accordance with such directions and instructions.

                    In any such event the Grid Operator shall promptly notify
                    the Executive Committee.

          50.2.8    Reference to the Director: If at any time the Grid Operator
                    has a concern which is properly and reasonably founded that,
                    in acting in accordance with any direction or instruction of
                    the Executive Committee or the Chief Executive, it will
                    breach one or more of its obligations under the Act or its
                    Transmission Licence, then, if having discussed the matter
                    with the Executive Committee the matter remains unresolved,
                    the Grid Operator shall either comply with such direction or
                    instruction or by notice in writing refer the same to the
                    Director, such notice to set out in full the directions or
                    instructions given to the Grid Operator and the grounds for
                    such concern and to be copied to the Executive Committee.
                    Pending any guidance from the Director in response to any
                    such reference and, provided that the Director shall not
                    express any view that such reference is misconceived,
                    vexatious or in respect of an improperly or unreasonably
                    founded concern, the Grid Operator shall not be liable to
                    any of the other Parties for refusing to act in accordance
                    with the relevant direction or instruction. If the Director
                    shall express such a view, the Grid Operator shall be so
                    liable.

51.5      Audit of Ancillary Services:

          51.5.1    The Suppliers may require the Pool Auditor to carry out
                    audits, tests, checks or reviews in relation to the
                    operation by the Ancillary Services Provider of the
                    Ancillary Services Business as Suppliers may from time to
                    time reasonably require (having regard, in particular, to
                    the disruptive effect of the same on the business and
                    operations of the Ancillary Services Provider). The terms of
                    engagement for any such audit, test, check or review shall
                    be made available to the Ancillary Services Provider.

          51.5.2    The Suppliers shall not require more than two audits, tests,
                    checks and reviews pursuant to Clause 51.5.1 in any
                    Accounting Period.

          51.5.3    On instructing the Pool Auditor pursuant to Clause 51.5.1,
                    the Supplier(s) concerned may require the Pool Auditor:-

                    (a)       forthwith to report any material concerns with
                              respect to matters the subject of the relevant
                              audit, test, check or review; and

                    (b)       to make such recommendations as to changes in the
                              procedures, controls and/or audit coverage of the
                              Ancillary Services Business as the Pool Auditor
                              considers appropriate.

          51.5.4    The Ancillary Services Provider shall permit the Pool
                    Auditor such access to its Ancillary Services' operations
                    and all records, documents, data and other information
                    (other than Excluded Information) held by the Ancillary
                    Services Provider in the conduct of such operations in each
                    case as the Pool Auditor may reasonably require and shall
                    make available members of its staff to explain such
                    operations and such other issues as the Pool Auditor
                    considers relevant. The Pool Auditor shall not disclose and
                    shall not be obliged to disclose to any Supplier details of
                    prices paid to each Generator by the Ancillary Services
                    Provider.

                    In this Clause 51.5 "Excluded Information" means all
                    records, documents, data and other information provided in
                    the course of the discussions or negotiations with any
                    person with whom the Ancillary Services Provider contracts
                    or considers contracting for the provision of Ancillary
                    Services other than as stated in any Ancillary Services
                    Agreement whether such discussions or negotiations take
                    place before contracting or as part of any price review
                    during the term of any Ancillary Services Agreement.

          51.5.5    The Pool Auditor shall report to the Suppliers and a copy of
                    any report by the Pool Auditor relating to an audit, test,
                    check or review pursuant to Clause 51.5.1 shall be provided
                    to the Ancillary Services Provider. The Pool Auditor

<PAGE>


                    shall owe a duty of confidentiality to the Ancillary
                    Services Provider save to the extent necessary to carry out
                    the particular audit, test, check or review provided that
                    any matter or thing set out in any report to the Suppliers
                    shall not be subject to any such obligation and provided
                    always that nothing in this Clause 51.5.5 shall prevent the
                    disclosure of any information pursuant to Clause 68. The
                    Ancillary Services Provider shall be entitled to rely on any
                    such report in any legal proceedings (including
                    arbitration).

          51.5.6    If the Suppliers so resolve, the Ancillary Services Provider
                    shall promptly implement any recommendations made by the
                    Pool Auditor in a report relating to an audit, test, check
                    or review pursuant to Clause 51.5.1 and, in the event of any
                    dispute, such dispute shall be referred to arbitration in
                    accordance with Clause 83.

          51.5.7    The cost of any audit, test, check or review pursuant to
                    Clause 51.5.1 shall be borne by the requisitioning
                    Supplier(s). The costs of implementing any recommendations
                    pursuant to Clause 51.5.6 may be recovered by the Ancillary
                    Services Provider in accordance with the ASP Accounting
                    Procedure.

51.6      Basis of Payment: The Ancillary Services Provider shall calculate the
          total amount payable under Ancillary Services Agreements in respect of
          each Settlement Day together with any amendments to calculations made
          for previous Settlement Days based upon information derived from the
          Grid Operator and the Settlement System Administrator. The charges to
          the Grid Operator for Ancillary Services shall comprise the costs so
          calculated together with the charges of the Ancillary Services
          Provider calculated in accordance with Schedule 18. The Ancillary
          Services Provider shall notify a provisional sum to the Settlement
          System Administrator within three working days after receipt of such
          information from the Grid Operator and the Settlement System
          Administrator so as to be despatched by the Settlement System
          Administrator to the Grid Operator in accordance with the relevant
          Agreed Procedure to enable the Settlement System Administrator to
          apportion this sum to the sale of Active Energy according to the Pool
          Rules. The Ancillary Services Provider shall notify a final sum to the
          Settlement System Administrator by such time as will enable the
          Settlement System Administrator to take into account the final
          Settlement Run for each Settlement Day. Any unresolved amount shall be
          included in the final Settlement Run on an interim basis pending
          resolution. Thereafter it may be included (together with any errors or
          omissions subsequently arising) in any appropriate Settlement Run.

51.7      Lost opportunity costs:

          51.7.1    Subject to Clause 51.6, where the Ancillary Services
                    Provider pays any Generator an amount in respect of lost
                    opportunity costs, the Ancillary Services Provider shall use
                    reasonable endeavours to include any such amount in its

<PAGE>


                    Ancillary Service charge to the Grid Operator in the
                    Settlement Day on which it arises or as soon as possible
                    thereafter.

          51.7.2    As soon as the Ancillary Services Provider is notified by
                    any Generator that any obligation to pay any lost
                    opportunity costs may arise, it shall consult the Suppliers
                    and the Grid Operator and, without prejudice to the
                    Ancillary Services Provider's right to recover such lost
                    opportunity costs from the Grid Operator in accordance with
                    Clause 51.6 or Clause 51.7.1, the Ancillary Services
                    Provider shall, if requested by the Suppliers or Grid
                    Operator, collect payment from the Grid Operator on account
                    of or by way of recovery of such costs over such period as
                    may be agreed between the Ancillary Services Provider, the
                    Suppliers and the Grid Operator and, in default of
                    agreement, over such period as the Ancillary Services
                    Provider considers to be reasonable.

51.8      Independent Contractor: The Ancillary Services Provider shall act as
          an independent contractor in carrying out its duties pursuant to this
          Agreement and (unless expressly authorised to the contrary) shall
          neither act nor hold itself out nor be held out as acting as agent for
          any of the other Parties.

51.9      Standard of care: In the exercise of its duties and responsibilities
          under this Agreement the Ancillary Services Provider shall exercise
          that degree of care, diligence, skill and judgment which would
          ordinarily be expected of a reasonably prudent operator of the
          Ancillary Services Business taking into account the circumstances
          actually known to the Ancillary Services Provider, its officers and
          employees at the relevant time or which ought to have been known to it
          or them had it or they made such enquiries as were reasonable in the
          circumstances.

51.10     Miscellaneous:

          51.10.1   (a)       The Ancillary Services Provider shall be entitled
                              to rely upon any direction or instruction of the
                              Executive Committee or the Chief Executive (if
                              any) if the same is signed by way of authority in
                              accordance with Clause 51.10.4 on behalf of two or
                              more Committee Members or on behalf of the Chief
                              Executive and shall not be obliged to comply with
                              any direction or instruction of any sub-committee
                              of the Executive Committee or any delegate of the
                              Executive Committee other than the Chief Executive
                              (unless such direction or instruction is shown as
                              having been ratified by the Executive Committee);

                    (b)       The Ancillary Services Provider shall be entitled
                              to rely upon any communication or document
                              reasonably believed by it to be genuine and
                              correct and to have been communicated or signed by
                              the person by whom it purports to be communicated
                              or signed and shall not be liable to any of the
                              Parties for any of the consequences of such
                              reliance.

<PAGE>


          51.10.2   Compliance with the Director's directions: No liability
                    whatsoever shall attach to the Ancillary Services Provider
                    as a result of due compliance by it with any directions and
                    instructions of the Director, provided that in complying
                    with such directions and instructions the Ancillary Services
                    Provider is at all times acting in good faith.

          51.10.3   Prior approval: Where by the terms of this Agreement the
                    Ancillary Services Provider is required to obtain the prior
                    directions, instructions, approval or consent of the
                    Executive Committee or the Chief Executive, the Ancillary
                    Services Provider shall have no authority to, and shall not,
                    act unless the requisite directions, instructions, approval
                    or consent have first been obtained. Notwithstanding the
                    foregoing sentence, nothing in this Agreement shall prevent
                    the Executive Committee from ratifying any act of the

                    Executive Committee or the Chief Executive to the Ancillary
                    Services Provider shall, as between the Ancillary Services
                    Provider and the Pool Members, be deemed to have the express
                    authority of, and shall be binding without reservation upon,

                    shall not be bound to act in accordance with the directions

                    act through the Executive Committee.

          51.10.6   General Meetings: The Ancillary Services Provider shall not
                    be obliged to take any steps to ascertain whether any
                    resolution of Pool Members in general meeting or of any
                    class of Pool Members in separate general meeting which it
                    is advised by the Executive Committee or the Chief Executive
                    as having been passed was in fact passed or passed by the
                    requisite majority and until the Ancillary Services Provider
                    shall have express written notice to the contrary from the
                    Executive Committee or the Chief Executive it shall be
                    entitled to assume that the relevant resolution was passed
                    or (as the case may be) the relevant requisite majority was
                    obtained.

          51.10.7   Exceptions: Notwithstanding the foregoing provisions of this
                    Clause 51.10, in the performance of its duties and
                    responsibilities under this Agreement the Ancillary Services
                    Provider shall not be bound to act in accordance with the
                    directions or instructions of the Executive Committee or the
                    Chief Executive:-

                    (a)       if to do so would cause the Ancillary Services
                              Provider to breach any of its obligations under
                              the Act or its Transmission Licence; or

<PAGE>


                    (b)       if the Ancillary Services Provider has reasonable
                              grounds for believing that it would so breach any
                              of such obligations and has consulted the Director
                              and the Director has not indicated that in his
                              view it would not involve any such breach; or

                    (c)       unless the Director has indicated that,
                              notwithstanding any such actual or potential
                              breach, the Director would not be minded to
                              enforce compliance with those obligations under
                              the Act or its Transmission Licence and the
                              Ancillary Services Provider has received an
                              indemnity reasonably satisfactory to it in respect
                              of its acting in accordance with such directions
                              and instructions.

                    In any such event the Ancillary Services Provider shall
                    promptly notify the Executive Committee.

          51.10.8   Reference to the Director: If at any time the Ancillary
                    Services Provider has a concern which is properly and
                    reasonably founded that, in acting in accordance with any
                    direction or instruction of the Executive Committee or the
                    Chief Executive, it will breach one or more of its
                    obligations under the Act or its Transmission Licence, then,
                    if having discussed the matter with the Executive Committee
                    the matter remains unresolved, the Ancillary Services
                    Provider shall either comply with such direction or
                    instruction or by notice in writing refer the same to the
                    Director, such notice to set out in full the directions or
                    instructions given to the Ancillary Services Provider and
                    the grounds for such concern and to be copied to the
                    Executive Committee. Pending any guidance from the Director
                    in response to any such reference and, provided that the
                    Director shall not express any view that such reference is
                    misconceived, vexatious or in respect of an improperly or
                    unreasonably founded concern, the Ancillary Services
                    Provider shall not be liable to any of the other Parties for
                    refusing to act in accordance with the relevant direction or
                    instruction. If the Director shall express such a view, the
                    Ancillary Services Provider shall be so liable.

51.11     Suppliers' Resolutions: Where any matter is reserved under this Part
          XI or Schedule 18 for the Suppliers to resolve, that matter shall be
          decided upon by the Suppliers in separate general meeting.

          "Consumer" and "Stage 2 Supplier" shall bear the respective meanings
          given to those terms in the Pool Rules.

                    more than four Generating Units (whether situate within
                    England and Wales or elsewhere). For the avoidance of doubt
                    a combined cycle module shall be deemed for these purposes a
                    single Generating Unit;

          54.3      the Centrally Despatched Generating Unit which is the
                    subject of the Scheme Admission Application has not at the
                    date of the Scheme Admission Application been Commissioned;

          54.4      the Centrally Despatched Generating Unit shall be admitted
                    for seven calendar years from the date of its admission to
                    the Scheme specified in the Scheme Admission Application;
                    and

          54.5      the Pool Member shall specify in the Scheme Admission
                    Application the proposed Scheme Planned Availability for
                    each Settlement Period in the proposed first Scheme Year for
                    the Centrally Despatched Generating Unit.

55.       RIGHTS AND OBLIGATIONS OF POOL MEMBERS

55.1      Notification of unavailability: In respect of each Scheme Year for
          each Scheme Genset (other than the first) the Pool Member shall not
          later than 28 days before the start of that Scheme Year for each
          Scheme Genset notify the Executive Committee of all Settlement Periods
          in that Scheme Year during which the Scheme Genset is intended to be
          unavailable.

55.2      Scheme Planned Availability: All Settlement Periods in that Scheme
          Year other than those notified under Clause 55.1 shall together
          constitute the Scheme Planned Availability in respect of that Scheme
          Genset for that Scheme Year.

55.3      Failure to notify: If the Pool Member fails to notify the Executive
          Committee in accordance with Clause 55.1 of the Scheme Planned
          Availability in respect of that Scheme Genset for the following Scheme
          Year, the Scheme Planned Availability shall be deemed to be the same
          as the Scheme Planned Availability for the current Scheme Year.

55.4      No amendment: The Scheme Planned Availability for any Scheme Year
          notified in accordance with Clause 55.1 or deemed in accordance with
          Clause 55.3 may not be amended.

<PAGE>


55.5      Payment rights: The Pool Member shall make or be entitled to receive
          payments in respect of each Scheme Genset as determined in accordance
          with Section 27 of Schedule 9 notwithstanding the expiry of the period
          referred to in Clause 50.4.

55.6      No withdrawal: The Pool Member may not withdraw any Scheme Genset from

55.7      Actual planned availability: In respect of each Scheme Genset, the
          Pool Member shall use all reasonable endeavours to ensure that the
          Scheme Planned Availability for each Scheme Year is the actual planned
          availability of such Scheme Genset.

56.       REVIEW

56.1      Review: Within two months after the end of the third Scheme Year in
          respect of which the first Scheme Genset has been admitted to the
          Scheme and each subsequent anniversary of that date the Executive
          Committee shall (with the consent of the Director) appoint an
          independent firm of accountants of internationally recognised standing
          to review the Scheme to establish whether or not any element of the
          Scheme (or the Scheme taken as a whole) gives rise to a systematic
          imbalance which is likely to prevent the payments to the Scheme
          balancing payments from the Scheme and to submit to the Executive
          Committee and the Director a report setting out details of any such
          imbalance and his findings and recommendations for amending the Scheme
          designed to correct any such imbalance.

56.2      Amendments: The Executive Committee may make such amendments to the
          provisions of Section 27 of Schedule 9 as are required to implement
          the recommendations referred to in Clause 56.1. Any such amendments
          shall apply in respect of any Scheme Admission Application received
          after the date such amendments become effective and shall constitute a
          new Scheme.

56.3      Existing rights and obligations continue: Any Pool Member shall remain
          entitled to the benefits and subject to the obligations of the Scheme
          with respect to any Scheme Genset in effect at the time of admission
          of that Scheme Genset to the Scheme.

                    Instruction (together with any Fuel Security Interest in
                    relation thereto) shall be treated as an amount which is due
                    to that Generator from those persons specified in that
                    Payment Instruction and which is payable on the basis
                    provided in that Payment Instruction; and

          58.1.2    any Fuel Security Reimbursement specified in that Payment
                    Instruction (together with any Fuel Security Interest in
                    relation thereto) shall be treated as an amount which is due
                    from that Generator to those persons specified in that
                    Payment Instruction and which is payable on the basis
                    provided in that Payment Instruction; and

          58.1.3    subject to Clauses 58.2 and 58.3, the Pool Funds
                    Administrator shall arrange for such Fuel Security Payment
                    or such Fuel Security Reimbursement (together with any Fuel
                    Security Interest in relation thereto) to be paid to or, as
                    the case may be, paid by that Generator by or, as the case
                    may be, to those persons specified in that Payment
                    Instruction in accordance with the provisions of such
                    Payment Instruction; and

          58.1.4    such Payment Instruction (including any calculation,
                    determination or other matter stated or specified therein)
                    shall, save in the case of fraud, be conclusive and binding
                    upon all Parties.

          the basis of payment of a Fuel Security Payment or a Fuel Security
          Reimbursement provided for in a Payment Instruction is unclear,
          contradictory or incomplete or that it is impossible to implement in
          full the basis of payment provided for in a Payment Instruction, then
          the Pool Funds Administrator must, promptly on becoming aware of the
          same, notify the Director in reasonable detail of the same and, until
          that matter is clarified, the Pool Funds Administrator shall only be
          obliged to implement the payment specified in that Payment Instruction
          to the extent that without clarification such implementation is
          possible.

          of that Generator) shall, to the extent that they have been set off as
          aforesaid, be deemed satisfied and extinguished.

59.6      Schedule 11: All payments made to or by any Generator in accordance
          with the provisions of a Payment Instruction shall, subject to any
          contrary instruction contained in the provisions of a Payment
          Instruction, be effected by the Pool Funds Administrator through the
          Banking System and the Billing System established in accordance with
          Schedule 11.

                              Party complying with the definition of Registrant
                              accepts such role as Registrant in accordance with
                              the provisions of this Agreement by service of a
                              duly completed notice in the form prescribed by
                              the relevant Agreed Procedure (but without

                              Administrator in the form prescribed by the
                              relevant Agreed Procedure); or

                    (iii)     the Metering System is registered in a PES
                              Registration Service as a Stage 2 Metering System.

          60.3.5    The Settlement System Administrator shall inform the
                    relevant Host PES of:-

                    (i)       the identity of any new Registrant; and

          60.3.8    If, other than by reason of the fault or negligence of the
                    Settlement System Administrator, a Stage 1 Metering System
                    ceases to have a Registrant who is not replaced as
                    Registrant in relation to the relevant Metering System, the
                    Settlement System Administrator shall not be obliged to take
                    the relevant Stage 1 Metering System into account for the
                    purposes of Stage 1 Settlement. The Settlement System
                    Administrator shall forthwith notify the Host PES and the
                    Executive Committee that it will not be taking such Stage 1
                    Metering System into account for the purposes of Stage 1
                    Settlement and the Parties shall comply with any directions
                    given by the Director in this matter.

          60.3.9    A Registrant may not resign or retire as Registrant except
                    in accordance with Clause 60.3.4.

          60.3.10   The Registrant in respect of any Stage 1 Metering System
                    shall provide to the Settlement System Administrator such
                    information as may be required by the relevant Agreed
                    Procedures.

          60.3.11   The Settlement System Administrator shall not enter on the
                    Register in respect of a Stage 1 Metering System a
                    Registrant in respect of which evidence of consent of the
                    Equipment Owner has not been provided in accordance with the
                    relevant Agreed Procedure.

          60.3.12   A Stage 1 Metering System for recording the output of a
                    Stage 1 Non-Pooled Generator must be capable of being
                    identified separately for the purposes of Stage 1 Settlement
                    from any Stage 1 Metering System recording demand. For the
                    avoidance of doubt, it is acknowledged that one set of
                    Metering Equipment may comprise more than one
                    separately-identified Stage 1 Metering System.

60.4      Operators:

          60.4.1    There must always be one and, at any point in time, no more
                    than one Operator for each Stage 1 Metering System which is
                    registered with the Settlement System Administrator. A
                    replacement Operator of such Stage 1 Metering System may be
                    appointed from time to time in accordance with the
                    provisions of this Part XV, Schedule 21 and the relevant
                    Agreed Procedure.

                    Non-Pooled Generator, which contain all or any part of the
                    same Metering Equipment, must have the same Operator.

          60.4.3    Any notice of a new Operator or of a change in Operator
                    (including upon resignation, removal or cessation in
                    accordance with the provisions of Schedule 21) or any Form
                    of Acknowledgement required under this Part XV or Schedule
                    21 shall be in such form and given to such person at such
                    time(s) and

<PAGE>


                    accompanied by payment of such fees (if any) as is
                    prescribed by the relevant Agreed Procedures. Where any
                    Meter Operator Party has not acknowledged its appointment as
                    Operator the Settlement System Administrator shall notify
                    the Registrant in accordance with the relevant Agreed
                    Procedure.

          60.4.4    The Registrant in respect of a Stage 1 Metering System shall
                    ensure that there is appointed from time to time an
                    Operator, which is a Meter Operator Party, in accordance
                    with, and for the purposes of, Schedule 21 as Operator in
                    respect of that Stage 1 Metering System.

          60.4.5    If a person which is an Operator in respect of any Stage 1
                    Metering System ceases to be an Operator in respect thereof
                    for whatever reason (including upon removal or resignation)
                    or ceases to be a Meter Operator Party (including upon
                    removal or resignation) and there has not been appointed, at
                    that time, a replacement Operator in respect of the relevant
                    Stage 1 Metering System(s) in accordance with the provisions
                    of this Part XV and Schedule 21, such person's
                    responsibilities as Operator of such Metering Equipment
                    shall upon such cessation be assumed by the Registrant in
                    respect of such Metering Equipment who shall be deemed to be
                    the Operator therefor (notwithstanding that it shall not be
                    registered as such by the Settlement System Administrator)
                    in accordance with the provisions of this Clause (the
                    "deemed Operator").

          60.4.6    If a person which is an Operator in respect of any Stage 1
                    Metering System at the site of a Stage 1 Non-Pooled
                    Generator ceases to be an Operator in respect thereof for
                    whatever reason (including upon removal or resignation) or
                    ceases to be a Meter Operator Party (including upon removal
                    or resignation) and there has not been appointed, at that
                    time, a replacement Operator in respect of the relevant
                    Stage 1 Metering System(s) in accordance with the provisions
                    of this Part XV and Schedule 21, such person's
                    responsibilities as Operator of the relevant Metering
                    Equipment shall upon such cessation be assumed by the
                    Registrant of the Stage 1 Metering System registered for
                    supply with respect to such Metering Equipment. Such
                    Registrant shall be deemed to be the Operator therefor
                    (notwithstanding that it shall not be registered as such by
                    the Settlement System Administrator) in accordance with the
                    provisions of this Clause (the "deemed Operator").

          60.4.7    As soon as any Registrant has reasonable grounds to believe
                    that an Operator of any Stage 1 Metering System in respect
                    of which it is the Registrant has ceased to act as Operator
                    therefor in accordance with substantially all of its
                    responsibilities as set out in Schedule 21 it shall remove
                    such Operator in respect of such Stage 1 Metering System in
                    accordance with sub-section 6.1 of Schedule 21.

<PAGE>


          60.4.8    If the Settlement System Administrator has reasonable
                    grounds to believe that an Operator of any Stage 1 Metering
                    System has ceased to act as Operator therefor in accordance
                    with substantially all of its responsibilities as set out in
                    Schedule 21 the Settlement System Administrator shall notify
                    the Registrant in accordance with the relevant Agreed
                    Procedure.

          60.4.9    Any Registrant which is deemed to be the Operator of a Stage
                    1 Metering System pursuant to the provisions of Clause
                    60.4.5 or 60.4.6 shall, subject to Clauses 60.4.10 and
                    60.4.11, continue to act as the Operator in respect of any
                    Stage 1 Metering System to which that Clause applies, or
                    shall appoint an agent or contractor which shall continue to
                    act as the Operator in respect of such Stage 1 Metering
                    System, for a period of 10 Business Days (which shall
                    commence at the time of the cessation referred to in Clause
                    60.4.5 or, as the case may be, 60.4.6) or, if a new Operator
                    is registered in respect of that Stage 1 Metering System
                    prior to the expiry of that period, for a period ending on
                    the date of such registration.

          60.4.10   If a Registrant to which Clause 60.4.9 applies does not act
                    as Operator in accordance with the provisions thereof or
                    does not appoint an agent or contractor who shall act as
                    Operator, or if the 10 Business Day period referred to in
                    Clause 60.4.9 shall expire without a replacement Operator
                    being registered with the Settlement System Administrator in
                    respect of that Stage 1 Metering System in accordance with
                    Section 4 of Schedule 21, that Registrant shall:-

                    (i)       undertake to cease forthwith to supply or to
                              generate or to take a supply of electricity for

                              electricity pursuant to this Agreement at the Site
                              where such supply or generation is measured,
                              recorded and communicated to the Settlement System
                              Administrator by that Stage 1 Metering System;

                    (ii)      notify the Settlement System Administrator in

                    exercise its right under Section 18 of Schedule 21 to
                    replace, renew or repair the defective Metering Equipment
                    (the "remedial work"); (y) the exercise of such right would
                    result in the incurring of significant capital expenditure;
                    and (z) the Register indicates that such Registrant is

                    apportioned so that the Grid Operator is liable for 5 per
                    cent. of the indemnified amount and the Pool Members are
                    liable for the balance of such indemnified amount in

                    calculated on the basis that the points allocated to the
                    Pool Member in default are disregarded) against any
                    liability which the Pool Funds Administrator may incur as a
                    result of the failure of any Pool Member, the Grid Operator

                    keep indemnified each non-defaulting Pool Member and (if it
                    is not in default) the Grid Operator (on an after tax basis,
                    but taking account of any tax relief available to the
                    relevant Pool Member or the Grid Operator, as the case may
                    be) against any liability which such non-defaulting Pool
                    Member and (if it is not in default) the Grid Operator shall

          disregarded) shall indemnify and keep indemnified the Grid Operator
          and/or the Relevant User (as the case may be) on demand against any
          and all liability, loss or damage which it may suffer or incur by

A Party shall not assign and/or transfer and shall not purport to assign and/or
transfer any of its rights and/or obligations under the Settlement Arrangements
provided that any Party may assign by way of security only all or any of its
rights over receivables arising under the Settlement Arrangements.

77.       COUNTERPARTS

This Agreement may be executed in any number of counterparts and by the
different Parties on separate counterparts, each of which when executed and

78.       WAIVERS; REMEDIES NOT CUMULATIVE

78.1      Waivers: No delay by or omission of any Party in exercising any right,
          power, privilege or remedy under the Settlement Arrangements shall
          operate to impair such right, power, privilege or remedy or be
          construed as a waiver thereof. Any single or partial exercise of any
          such right, power, privilege or remedy shall not preclude any other or
          further exercise thereof or the exercise of any other right, power,
          privilege or remedy.

78.2      Remedies not cumulative: The rights and remedies provided by the
          Settlement Arrangements to the Parties are exclusive and not
          cumulative and exclude and are in place of all substantive (but not
          procedural) rights or remedies express or implied and provided by
          common law or statute in respect of the subject matter of the
          Settlement Arrangements (other than any such rights or remedies
          provided under section 58 of the Act or any directions (if any) issued
          thereunder), including any rights any Party may possess in tort which
          shall include actions brought in negligence and/or nuisance.
          Accordingly, each of the Parties hereby waives to the fullest extent
          possible all such rights and remedies provided by common law or
          statute, and releases a Party which is liable to another (or others),
          its officers, employees and agents to the same extent from all duties,
          liabilities, responsibilities or obligations provided by common law or
          statute in respect of the matters dealt with in this Agreement and
          undertakes not to enforce any of the same except as expressly provided
          herein.

78.3      Director's and Secretary of State's rights: For the avoidance of
          doubt, the Parties acknowledge and agree that nothing in the
          Settlement Arrangements shall exclude or restrict or otherwise
          prejudice or affect any of the rights, powers, privileges, remedies,
          duties and obligations of the Secretary of State or the Director under
          the Act or any Licence or otherwise howsoever.

79.      SEVERANCE OF TERMS

If for any reason whatever any provision of the Settlement Arrangements is or
becomes invalid, illegal or unenforceable, or is declared by any court of
competent jurisdiction or any other Competent Authority to be invalid, illegal
or unenforceable or if such Competent Authority:-

(a)       refuses, or formally indicates an intention to refuse, authorisation
          of, or exemption to, any of the provisions of or arrangements
          contained in the Settlement Arrangements (in the case of a refusal
          either by way of outright refusal or by way of requiring the amendment
          or deletion of any provision of the Settlement Arrangements and/or the
          inclusion of any provision in the Settlement Arrangements and/or the
          giving of undertakings or the acceptance of conditions as to future
          conduct before such authorisation or exemption can be granted); or

(b)       formally indicates that to continue to operate any provision of the
          Settlement Arrangements may expose the Parties to sanctions under any
          law, order, enactment or regulation, or requests any Party to give
          undertakings or to accept conditions as to future conduct in order
          that such Party may not be subject to such sanctions

and, in all cases, whether initially or at the end of any earlier period or
periods of exemption then, in any such case, the Parties will negotiate in good
faith with a view to agreeing one or more provisions which may be substituted
for such invalid, unenforceable or illegal provision which substitute
provision(s) is(are) satisfactory to the Competent Authority(ies) and produce(s)
as nearly as is practicable in all the circumstances the appropriate balance of
the commercial interests of the Parties.

80.       ENTIRE AGREEMENT

The Settlement Arrangements contain or expressly refer to the entire agreement
between the Parties with respect to the subject matter thereof and expressly
exclude any warranty, condition or other undertaking implied at law or by custom
and supersedes all previous agreements and understandings between the Parties
with respect thereto and each of the Parties acknowledges and confirms that it
does not enter into this Agreement in reliance on any representation, warranty
or other undertaking not fully reflected in the terms of the Settlement
Arrangements.

81.       LANGUAGE

Each notice, instrument, certificate or other document to be given by one Party
to another hereunder shall be in the English language.

82.       RESTRICTIVE TRADE PRACTICES ACT 1976

If after the commencement of section 100 of the Act (the "RTP Section") this
Agreement is subject to registration under the Restrictive Trade Practices Act
1976, and if it is not a

<PAGE>


non-notifiable agreement under that Act, then NGC undertakes, no earlier than
five months but no later than six months after the commencement of the RTP
Section, to furnish to the Director General of Fair Trading particulars of this
Agreement and of any agreement of which it forms part. Before furnishing such
particulars NGC will consult with the Founder Generators and the Founder
Suppliers as to the nature of the particulars to be so furnished and will
consult with the Founder Generators and Founder Suppliers regularly regarding
the progress of discussions with the Director General of Fair Trading in regard
to the agreement(s) so furnished.

83.       ARBITRATION

83.1      Referral to arbitration: Save where expressly stated in this Agreement
          to the contrary and subject to any contrary provision of the Act or
          any Licence or the rights, powers, duties and obligations of the
          Director or the Secretary of State under the Act, any Licence or
          otherwise howsoever, any dispute or difference of whatever nature
          howsoever arising under, out of or in connection with the Settlement
          Arrangements between any one or more Parties shall be and is hereby
          referred to arbitration pursuant to the arbitration rules of the
          Electricity Arbitration Association in force from time to time.

83.2      Proper law: Whatever the nationality, residence or domicile of any
          Party 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 seat of any such arbitration
          shall be England and Wales and the provisions of the Arbitration Act
          1996 shall apply to any such arbitration wherever the same or any part
          of it shall be conducted.

83.3      Third Party Claims (1): Subject always to Clause 83.6, if any tariff
          customer (as defined in section 22(4) of the Act) 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 (the "Defendant Contracting Party"), and the
          Defendant Contracting Party wishes to make a Third Party Claim (as
          defined in Clause 83.5) against any other Party (a "Contracting
          Party") which would but for this Clause 83.3 have been a dispute or
          difference referred to arbitration by virtue of Clause 83.1 then,
          notwithstanding the provisions of Clause 83.1 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 Contracting Party but also
          between either or both of them and any other Contracting Party whether
          by way of third party 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.

83.4      Third Party Claims (2): Where a Defendant Contracting Party makes a
          Third Party Claim against any Contracting Party and such Contracting
          Party wishes to make a Third Party Claim against a further Contracting
          Party the provisions of Clause 83.3 shall apply

<PAGE>


          mutatis mutandis as if such Contracting Party had been the Defendant
          Contracting Party and similarly in relation to any such further
          Contracting Party.

83.5      Third Party Claims (3): For the purposes of this Clause 83 "Third
          Party Claim" shall mean:-

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

          83.5.2    any claim by a Defendant Contracting Party against such a
                    Contracting 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

          83.5.3    any requirement by a Defendant Contracting 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
                    Contracting Party but also as between either or both of them
                    and a Contracting Party (whether or not already a party to
                    the legal proceedings).

83.6      Limitation: Clause 83.3 shall apply only if at the time the legal
          proceedings are commenced no arbitration has been commenced between
          the Defendant Contracting Party and another Contracting 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.

83.7      Emergency relief: Notwithstanding the rest of this Clause 83, any
          Party may apply at any time to any court of competent jurisdiction for
          emergency interim interlocutory relief as may be necessary.

84.       JURISDICTION

84.1      Submission to jurisdiction: Subject and without prejudice to Clauses
          83 and 84.4, all the Parties irrevocably agree that the courts of
          England are to have exclusive jurisdiction to settle any disputes
          which may arise out of or in connection with the Settlement
          Arrangements and that accordingly any suit, action or proceeding
          (together in this Clause 84 referred to as "Proceedings") arising out
          of or in connection with the Settlement Arrangements may be brought in
          such courts.

84.2      Waiver: Each Party irrevocably waives any objection which it may have
          now or hereafter to the laying of the venue of any Proceedings in any
          such court as is referred to in this

<PAGE>


          Clause and any claim that any such Proceedings have been brought in an
          inconvenient forum and further irrevocably agrees that a judgment in
          any Proceedings brought in the English courts shall be conclusive and
          binding upon such Party and may be enforced in the courts of any other
          jurisdiction.

84.3      Agent for service of process: Each Party which is not incorporated in
          any part of England or Wales agrees that if it does not have, or shall
          cease to have, a place of business in England or Wales it will
          promptly and hereby does appoint the Settlement System Administrator
          (or such other person as shall be acceptable to the Executive
          Committee) irrevocably to accept service of process on its behalf in
          any Proceedings in England.

84.4      Arbitration: For the avoidance of doubt nothing contained in the
          foregoing provisions of this Clause 84 shall be taken as permitting a
          Party to commence Proceedings in the courts where this Agreement
          otherwise provides for Proceedings to be referred to arbitration.

85.       GOVERNING LAW

The Settlement Arrangements shall be governed by, and construed in all respects
in accordance with, English law.

4.1       Standard of care: Subject to sub-sections 4.2 and 4.3, in the exercise
          of its duties and responsibilities under the SSA Arrangements the
          Settlement System Administrator shall exercise that degree of care,
          diligence, skill and judgment which would ordinarily be expected of a
          reasonably prudent operator of the Stage 1 Settlement System taking
          into account the circumstances actually known to the Settlement System
          Administrator, its officers and employees at the relevant time or
          which ought to have been known to it or them had it or they made such
          enquiries as were reasonable in the circumstances. In particular, but
          without prejudice to the generality of the foregoing, in the absence
          of directions and instructions given to it by the Executive Committee
          or the Contract Manager under the SSA Arrangements and having due
          regard to the constraints imposed on the Settlement System
          Administrator by the Charging Procedure and the resources available to
          it, the Settlement System Administrator shall at all times conduct
          itself in a manner calculated to achieve the principal objects and
          purpose of this Agreement set out in Clauses 4.1.2 and 4.1.3.

4.2       Service Line: If the standard required of the Settlement System
          Administrator for the performance of a Service is included in the
          Service Line for that Service, such standard shall be deemed to be the
          standard to which the Settlement System Administrator will be required
          to perform to discharge its duty of care under sub-section 4.1 in
          respect of that Service.

4.3       Qualification to the standard of care: If the Executive Committee or
          the Contract Manager orders from a third party software design or
          integration services which are similar to the software design or (as
          the case may be) integration services that are the subject of Service
          Line 19 (System Integration), then the Settlement System Administrator
          shall not be deemed to be in breach of its standard of care under the
          SSA Arrangements set out in sub-section 4.1 if and to the extent that
          such breach is a direct result of the Settlement System Administrator
          being required to operate new or changed software components to the
          Stage 1 Settlement System which have been so designed

<PAGE>

          and/or integrated by the third party without the Settlement System
          Administrator being given a reasonable opportunity to satisfy itself
          about the design of such components or (as the case may be) the manner
          of such integration.

          agents shall be liable to any of the other Parties for loss arising

          resulting from such breach and which at the date of this Agreement was
          reasonably foreseeable as not unlikely to occur in the ordinary course
          of events from such breach in respect of:-

          (i)       physical damage to the property of any of the other Parties
                    or its or their respective officers, employees or agents;

          agents and the Settlement System Administrator shall indemnify and

         indemnity to be payable, neither the Settlement System Administrator
         nor any of its officers, employees or agents shall in any circumstances
         whatsoever be liable to any of the other Parties for:-

                    contract or loss of goodwill; or

          foregoing provisions of this Section 4 have been the subject of

                    entitle such other party to claim damages or to bring
                    proceedings for an injunction.

                              Settlement System Administrator shall procure that
                              all intellectual property rights in such Software
                              shall vest in the Settlement System Administrator.

          8.2.2     Pool Members confirm and agree:-

                    (i)       that they have no objection to intellectual
                              property rights referred to in paragraph 8.2.1
                              being held in this way; and

                    (ii)      that, subject to the remaining provisions of this
                              Section 8 and to Section 9, the Settlement System
                              Administrator shall have the right of use of such
                              intellectual property rights as an absolute owner.

          8.2.3     The Settlement System Administrator hereby grants to Pool
                    Members a royalty free, non-exclusive, irrevocable,
                    perpetual and transferable licence to use, copy and develop
                    the Software referred to in paragraph 8.2.1 without
                    limitation or restriction for the purposes of operating the
                    Settlement System within the United Kingdom. The licence
                    granted hereunder may be assigned by Pool Members, without
                    limitation or restriction, to their nominee. If Pool Members
                    or their nominee, as the case may be, should wish to use,
                    copy or develop any such Software in any territory outside
                    the United Kingdom or for any purpose other than the
                    operation of the Settlement System, then the Settlement
                    System Administrator shall grant to Pool Members or their
                    nominee, as the case may be, a licence so to use, copy or
                    develop such Software in such territory on fair and
                    reasonable commercial terms.

          8.2.4     For the avoidance of doubt, this sub-section 8.2 shall not
                    apply to Settlement Goal.

8.3       Licensed software: In respect of any other Software, not developed
          internally, purchased or commissioned, the Settlement System
          Administrator shall ensure that it has a fully transferable licence
          (such transfer to include the transfer to any successor Settlement
          System Administrator) to use and develop such Software, together with
          (unless the Executive Committee otherwise notifies the Settlement
          System Administrator) suitable escrow arrangements for any Software
          for which the source code and full documentation has not been provided
          or which is not freely available. No further fee shall be payable in
          respect of any transfer of the licence to any nominee of Pool Members
          under Section 21 except to the extent that the licensor may continue
          to charge the same licence fees to the transferee.

8.4       Third party maintenance: Except in circumstances beyond the Settlement
          System Administrator's control, the SSA System shall be fully
          maintained, by third party

<PAGE>

          maintenance organisations to the extent that the Software is not
          developed internally, and the SSA System shall be fully documented so
          that it can be operated by any successor to the Settlement System
          Administrator. The Settlement System Administrator shall promptly
          notify the Executive Committee upon the Settlement System
          Administrator becoming aware that the SSA System will cease to be
          maintained by such a third party maintenance organisation.

8.5      SSA System changes: The Settlement System Administrator shall be free
         to make any changes to the SSA System, except to the extent that (a)
         the modification necessitates any change to the Developed Application
         Software or Licensed Application Software or (b) it detrimentally
         affects the operation of the Settlement System or (c) it necessitates
         any change to the ISRA System or the Stage 2 Software or any other
         aspect of the Stage 2 Settlement System to and from which the SSA
         System (or any part thereof) has an interface.

8.6      Maintenance of the SSA System Software: Without prejudice to Section
         10, in respect of any Software related to the SSA System which is
         written, commissioned or customised by the Settlement System
         Administrator, the Settlement System Administrator shall maintain
         support for, and where necessary fix any bugs in, such Software from
         the Termination Date until the expiry of the Post-Termination Period,
         if any, and the costs of maintaining that support and fixing the bugs
         shall be as agreed between the Settlement System Administrator and the
         Contract Manager and shall be recovered in accordance with the Charging
         Procedure.

8.7      Settlement Goal:

          8.7.1     The Settlement System Administrator shall be deemed to have
                    complied with its obligations set out in sub-section 8.3
                    solely in so far as they relate to Settlement Goal if it has
                    entered into and has in force a licence agreement with NGC
                    in the terms of the Type 1 Goal Licence.

          8.7.2     The Settlement System Administrator shall be deemed to have
                    complied with its obligations set out in the first sentence
                    of sub-section 8.4 solely in so far as they relate to
                    Settlement Goal if it has entered into and has in force a
                    support and maintenance agreement with NGC in the terms of
                    the Type 1 Support and Maintenance Agreement.

          8.7.3     Where the introduction of a Settlement Goal Enhancement or
                    Emergency Fix to Settlement Goal causes or occasions changes
                    to be required to the SSA System, all costs associated with
                    such changes shall be recharged to Pool Members in
                    accordance with the Charging Procedure.

                              less favourable to it than the terms of the
                              licence held by the Settlement System
                              Administrator and without payment of a fee by Pool

                              fee to the transferee or in the case of a Type 1
                              Goal Licence such other fee as may be specified in

9.3       Re-engineered Settlement System: For the avoidance of doubt, all
          Parties agree that all existing and future intellectual property
          rights of whatsoever nature subsisting in the Re-engineered Settlement
          System (as defined in the Appendix) shall vest in Pool Members or, at
          the direction of the Executive Committee, in a nominee of Pool
          Members. The Settlement System Administrator hereby assigns to Pool
          Members or their nominee, as the case may be, with full title
          guarantee all such existing and (to the extent that future assignment
          is permitted by law) all future intellectual property rights that
          exist or may exist in the Re-engineered Settlement System and, to the
          extent that such future intellectual property rights that exist, or
          may exist, in such Re-engineered Settlement System are not hereby
          assigned to Pool Members or their nominee, as the case may be, the
          Settlement System Administrator undertakes to do all such acts and
          execute all such documents as may be necessary or desirable to give
          full effect to the assignment of such intellectual property rights.

                    procedure or a remedy to such Software to allow for the
                    continued running of such Software in accordance with its
                    specification provided that the Settlement System
                    Administrator shall be deemed to have complied with the
                    provisions of this sub-section 10(a), solely in so far as
                    they relate to Settlement Goal, if it has entered into and
                    has a current Type 1 Support and Maintenance Agreement;

                    Developed Application Software and the Licensed Application
                    Software.

          single, major respect to perform or comply with any of the obligations
          expressed to be assumed by it under the SSA Arrangements and such
          failure, in the reasonable opinion of the Executive Committee, is
          capable of remedy, the Executive Committee shall have the right to
          give notice in writing (the "Remediable Removal Notice") to the
          Settlement System Administrator giving details of the relevant failure
          and requiring that such failure be remedied within 30 days (or such

          as may be necessary but in any event within 90 days or any longer
          period as may be reasonable and agreed between the Settlement System
          Administrator and the Executive Committee) from the date of receipt by
          the Settlement System Administrator of the Remediable Removal Notice
          and, if a longer period is reasonable, that within 30 days from the
          said date of receipt the Settlement System Administrator agree a
          timetable with the Executive Committee for the remedy of such failure
          (such agreement not to be unreasonably withheld).

17.2      Breach of obligations incapable of remedy: If the Settlement System
          Administrator fails in any persistent, material respect or in any
          single, major respect to perform or comply with any of the obligations

          Removal Notice") to the Settlement System Administrator giving details
          of the relevant failure and stating that, in the reasonable opinion of
          the Executive Committee, the Settlement System Administrator is in
          breach of the terms of the SSA Arrangements and such breach is
          incapable of remedy.

17.3      Insolvency: If the Settlement System Administrator:-

          (a)       is unable to pay its debts (within the meaning of section

                    hereinafter provided in this sub-section 17.3) or if any
                    voluntary agreement is proposed in relation to it under
                    section 1 of that Act or if the Settlement System

          (b)       has a receiver (which expression shall include an
                    administrative receiver within the meaning of section 29 of
                    the Insolvency Act 1986) of the whole or any material part

          (in this sub-section 17.3, the "Irremediable Removal Notice") to the
          Settlement System Administrator referring to such event.

<PAGE>

          For the purposes of paragraph (a) above section 123(1)(a) of the
          Insolvency Act 1986 shall have effect as if for "(pound)750" there
          were substituted "(pound)250,000" and, further, the Settlement System
          Administrator shall not be deemed to be unable to pay its debts for
          the purposes of paragraph (a) above if any such demand as is mentioned
          in the said section is being contested in good faith by the Settlement
          System Administrator with recourse to all appropriate measures and
          procedures.

17.4      Change of Status: If ESIS ceases to be a wholly-owned subsidiary of
          NGC then, subject to the prior written consent of the Director having

          notice in writing (in this sub-section 17.4, the "Irremediable Removal

                    unable to remedy the failure within 30 days from the date of
                    receipt of the Remediable Removal Notice (or such longer
                    period as may be permitted under sub-section 17.1) or, as
                    the case may be, within the period provided in the timetable

                    resolving to remove ESIS as Settlement System Administrator

                              there is no more than one dissentient Pool Member;

          (ii)      the Director has given his prior written consent in the
                    light of the resolution passed in accordance with
                    sub-paragraph (i) above; and

<PAGE>

          (iii)     the Executive Committee has given the Settlement System
                    Administrator after such resolution has been passed or

                    17, the "Removal Notice") of such removal to take effect on
                    the date specified in the Removal Notice (in this Section
                    17, the "Termination Date") and, subject to Section 20, the

                    terminate on the Termination Date.

18.       POWERS OF EXECUTIVE COMMITTEE ON RESIGNATION AND REMOVAL

Executive Committee Powers: At any time and from time to time on or after a

Committee shall have the right:-

          (a)       subject to all security, safety and operational constraints
                    of the Settlement System Administrator current at the time

                    Notice is given, to enter (and any third party reasonably
                    nominated by the Executive Committee shall have the right to
                    enter) upon reasonable notice any premises where the

                    functions relating to the Stage 1 Settlement System to
                    inspect any aspect of the Stage 1 Settlement System, to
                    ensure maintenance of service levels and to facilitate the
                    transfer of service, responsibilities and assets pursuant to
                    Section 21; and

          (b)       on such reasonable basis as may be agreed with the
                    Settlement System Administrator (such agreement not to be
                    unreasonably withheld), to communicate with and consult such
                    of the Settlement System Administrator's staff as are
                    available as the Executive Committee reasonably considers to
                    be essential to the Stage 1 Settlement System for a period
                    up to 12 months following the Termination Date.

19.       APPOINTMENT OF SUCCESSOR SETTLEMENT SYSTEM ADMINISTRATOR

19.1      Approval of the Director: The Parties undertake with each other that
          no successor Settlement System Administrator shall be appointed
          without the written approval of the Director first having been
          obtained.

19.2      Discharge: With effect from the Termination Date ESIS in its capacity
          as Settlement System Administrator shall (save as provided in

          further rights under the SSA Arrangements but shall remain entitled to
          the benefit of the provisions of sub-sections 4.3 to 4.9 (inclusive)
          and any other provision of this Agreement providing for an indemnity
          or the payment of other costs or charges in favour

          provided in this sub-section 19.2) each of the other Parties shall
          have the same rights and obligations amongst themselves as they would
          have had if such successor had been a party to this Agreement in place
          of ESIS as Settlement System Administrator.

20.       CONTINUATION OF SERVICES

20.1      Continuation of Services: Subject to sub-section 20.5, the Executive
          Committee shall have the right to postpone the Termination Date beyond
          its original date on a maximum of four occasions and, on each

          and ESIS agrees to continue to act as Settlement System Administrator
          for the duration of each Extension Period. The Executive Committee
          shall exercise such right by written notice to the Settlement System
          Administrator specifying the duration of each Extension Period (each
          an "Extension Notice"), and the Termination Date shall thereupon be
          postponed to the last day of the then proposed Extension Period.

20.2      Post-Termination Services: The Contract Manager may, by placing an
          Order, request the Settlement System Administrator to provide such
          training and support services as are set out in the Menu of
          Consultancy Services Prices and the Menu of Development Services
          Prices (each as defined in the Appendix hereto) as the Executive
          Committee may reasonably require for the Post-Termination Period. Any
          such Order shall specify the length of time for which such services
          are required. Subject to sub-section 20.4, the Settlement System
          Administrator shall be entitled to charge for such services in
          accordance with the Menu of Prices current immediately prior to the
          Termination Date (subject to indexation in accordance with the terms
          of the Appendix hereto) but shall only be required to provide such
          services to the extent that the resources are at the time employed by
          ESIS or were formerly employed by ESIS and are at the time employed
          within the NGC group of companies.

20.3      Extension Period Charges: The Settlement System Administrator shall
          have the right to charge for Services rendered during the Extension
          Period in accordance with Section 1 of Part H of the Appendix hereto.

          shall charge only a nominal sum (being not more than (pound)100 in the
          aggregate) for such training and support services rendered in
          accordance with sub-section 20.2 where the Termination Date is
          referable to a Resignation Notice given by ESIS pursuant to Section 14
          or a Removal Notice given by the Executive Committee pursuant to
          Section 17.

20.5      Two year limit: Notwithstanding any other provision of this Agreement,
          the Executive Committee shall not be entitled to require ESIS to
          remain appointed as Settlement System Administrator after the date
          falling 24 months after the date on which:-

<PAGE>

          (a)       the Settlement System Administrator gives the Executive
                    Committee a Resignation Notice; or (as the case may be)

          (b)       the Executive Committee gives the Settlement System
                    Administrator a Removal Notice.

20.6      Full force and effect: All the provisions of this Schedule and the
          Appendix hereto shall remain in full force and effect for the duration
          of the Extension Period (if any) and the Post-Termination Period (if
          any) to the extent necessary to give effect to the terms of this
          Section 20.

21.       TRANSFER OF SERVICES, RESPONSIBILITIES AND ASSETS

21.1      Transfer of services, responsibilities and assets: Upon a successor
          Settlement System Administrator being appointed under Section 19 and
          accepting such appointment ESIS in its capacity as outgoing Settlement
          System Administrator shall:-

          (a)       grant to a nominee of the Pool Members (who may be the
                    successor Settlement System Administrator) a royalty free,
                    non-exclusive, irrevocable, perpetual and transferable
                    licence of all Software which for the avoidance of doubt
                    shall exclude Settlement Goal, all related documentation and
                    other similar intellectual property rights belonging to the
                    outgoing Settlement System Administrator free of charge, to
                    use, copy, adapt and translate such Software and other
                    property for any purpose related to the operation of the
                    Stage 1 Settlement System;

          (b)       use all reasonable endeavours to novate, or procure the
                    novation of, any licence or other agreement to use and/or
                    maintain software and other property related to the
                    operation of the Stage 1 Settlement System provided that in
                    respect of Settlement Goal such obligation shall be subject
                    to the provisions of the Type 1 Goal Licence;

          (c)       transfer to such successor all Hardware belonging to the
                    outgoing Settlement System Administrator and essential to
                    such successor to carry out such successor's duties and
                    responsibilities under the SSA Arrangements and which is not
                    otherwise readily obtainable by such successor;

          (d)       make over to such successor copies of all such records,
                    manuals and data and other information not referred to in
                    sub-section 21.1(a) and in the ownership or under the
                    control of the outgoing Settlement System Administrator and
                    relating to the operation, and necessary for the proper
                    functioning of the Stage 1 Settlement System; and

          (e)       without prejudice to the foregoing provisions of this
                    Section 21, transfer or otherwise make available to such
                    successor all assets (excluding freehold and

<PAGE>

                    leasehold property), equipment, facilities, rights, know-how
                    and transitional assistance which it possesses and which is
                    necessary for such successor to have to operate the Stage 1
                    Settlement System in accordance with the SSA Arrangements
                    and which is not otherwise readily obtainable by such
                    successor,

          in each case on such reasonable terms (other than as to consideration)
          as may be agreed between ESIS, such successor and the Executive
          Committee (and, in default of agreement, the dispute shall be referred
          to arbitration in accordance with Clause 83) and in consideration of
          the payment of such sums as are referred to in sub-section 21.2. ESIS
          further agrees, in consideration of the payment of such sums as are
          referred to in sub-section 21.2, to co-operate with any such successor
          and the Executive Committee so that the transfer of duties, services,
          responsibilities, assets and know-how to such successor is carried out
          causing as little disruption to the operation of the Settlement System
          and inconvenience to the Parties and Pool Agents as is practical in
          all the circumstances.

21.2      Asset Transfer Costs:

          21.2.1    The consideration referred to in sub-section 21.1 is:-

                              (i)       the right to use all Software, related
                                        documentation and other similar

notice from the Settlement System Administrator giving details of the relevant
failure and requiring its remedy (or such longer period as may be necessary but
in any event within 90 days or any longer period as may be reasonable and agreed
between the Settlement System Administrator and the Executive Committee) and,
where such reasonable period is longer than 30 days, a timetable for the remedy
of such failure is not agreed by the Executive Committee with the Settlement
System Administrator (such agreement not to be unreasonably withheld) within 30
days from the said date of receipt, then ESIS may (the prior written consent of
the Director having been obtained):-

          (a)       give not less than 12 months' notice in writing to the

                    on that date and the provisions of Section 24 shall apply as

                    Administrator shall have been terminated by its removal in
                    accordance with Section 16 (but disregarding for this
                    purpose any requirement to pay Compensation if the
                    appointment of ESIS as Settlement System Administrator in
                    fact terminates after 31st March, 1999); or

          (b)       give notice to all Pool Members, the Executive Committee and

                    breach or failure to remedy or agree a timetable for remedy
                    of a remediable breach and, if at any time after the service
                    of such notice and while such breach is continuing, the
                    Settlement System Administrator resigns or is removed
                    pursuant to Section 14, 15, 16 or 17 then, notwithstanding
                    Sections 22, 23 and 25, the provisions of Section 24 shall
                    apply as if the appointment of ESIS as Settlement System
                    Administrator shall have been terminated by its removal in
                    accordance with Section 16 (but disregarding for this
                    purpose any requirement to pay Compensation if the
                    appointment of ESIS as Settlement System Administrator in
                    fact terminates after 31st March, 1999).

29.       VARIATION OF SERVICE LINES

If the Executive Committee engages a person other than the Settlement System
Administrator to perform a Service contained in a Service Line or part thereof
which is listed in the Sole Supplier Index there shall be deemed to be a failure
by the Executive Committee in a single, major respect to comply with its
obligations under the SSA Arrangements or the Settlement System Administrator
shall be entitled to insist upon due and proper performance of the SSA
Arrangements provided that the mere variation of any Service Line to a state
where no Service is to be provided or can be Ordered thereunder shall not be
deemed to be such a failure.

30.       EXTENSION OF TIME

If performance of the terms of the SSA Arrangements by the Settlement System
Administrator is delayed by reason of the act or default of a Party (not being
the Settlement System Administrator), a Meter Operator Party or a Pool Agent or
a nominee to whom intellectual property rights in the Software have been
transferred pursuant to Section 8 or 9, the Settlement System Administrator
shall be entitled to a reasonable extension of time for performance and to any
reasonable additional costs which it can demonstrate to the Executive Committee
were directly incurred as a result of such delay provided always and on
condition that the Settlement System Administrator shall notify the Executive
Committee in writing within a reasonable time of the circumstances giving rise
to the delay in performance.

          are expected to facilitate that day-to-day operation. The Parties
          agree that a failure by a Party to comply with the Contract Management

                    so agree and reach agreement as to the changes in prices,
                    any such price change

<PAGE>

36.       CONTRACT TRANSFER

If Pool Members so resolve in general meeting, the Settlement System
Administrator and the Executive Committee shall negotiate in good faith to give
effect to the terms of engagement of ESIS as Settlement System Administrator by
means of an agreement separate from this Agreement between the Settlement System
Administrator and a nominee of Pool Members (such nominee to be a limited
liability company in which some or all of the Pool Members are investors or some
or all of the obligations of which, including its obligations to ESIS as
Settlement System Administrator, they financially support). The terms and
conditions of such substitute agreement shall (taken as a whole) not be
materially less favourable to the parties thereto than are enjoyed by the
Parties under the SSA Arrangements and each Party agrees that it will not
unreasonably withhold its consent to any amendment to the SSA Arrangements or,
if required, to the substitute agreement in order to give effect to the
foregoing provisions of this Section.

37.       YEAR 2000 COMPLIANCE

37.1      Software Compliant: The Settlement System Administrator warrants and
          undertakes to ensure that the Stage 1 Software, the Developed
          Application Software, the Licensed Application Software, all as
          existing as at 31st December, 1997, are and will remain Millennium
          Compliant for a period of 368 days commencing at 00.00 hours on 31st
          December, 1999 save that the provisions of this sub-section 37.1 shall
          not apply to Settlement Goal.

37.2      ESIS Compliant: The Settlement System Administrator warrants and
          undertakes to ensure that the Stage 1 Hardware and the SSA System are
          and will remain Millennium Compliant for a period of 368 days
          commencing on 31st December, 1999.

37.3      No breach for non-compliant data: For the avoidance of doubt, the
          Settlement System Administrator shall not be deemed to be in breach of
          its obligations under this Section 37 where the Stage 1 Settlement
          System or the SSA System is unable to process results because its data
          input validation software rejects data not originating from the Stage
          1 Settlement System or (as the case may be) the SSA System where such
          data is itself not Millennium Compliant.

<PAGE>

37.4      Continuance: The warranties and undertakings of the Settlement System
          Administrator under sub-sections 37.1 and 37.2 shall survive the

          (c)       if agreed to be provided, will not be included in a Service
                    Line or a Menu of Prices but will be provided on stand-alone
                    terms and conditions,

and, for the avoidance of doubt, any service or obligation of the Settlement
System Administrator pursuant to the SSA Arrangements which is not described in
a Service Line is a Non-Menu Service.

6.        PRICE ON REQUEST ITEMS

Price on Request Items are those Services designated as Price on Request in the
Service Lines, being services for which there is a general description in one or
more of the Service Lines but for which there is no corresponding price stated
or referred to in any Menu of Prices and for which the Settlement System
Administrator will quote a price in accordance with Section 2 of Part C and
which may or may not be added to the relevant Menu of Prices.

7.        SOLE SUPPLIER SERVICES

7.1       Sole Supplier Services: Those Services or parts thereof which for the
          time being and from time to time are listed in the Sole Supplier Index
          are known as Sole Supplier Services.

7.2       Status of Sole Supplier Services: Subject to sub-section 7.2 of
          Schedule 4, Sole Supplier Services may only be provided by the
          Settlement System Administrator. If the Executive Committee shall
          engage a person other than the Settlement System Administrator to
          perform a Sole Supplier Service, there shall be deemed to be a failure
          by the Executive Committee in a single, major respect to comply with
          its obligations under the SSA Arrangements for the purposes of Section
          28 of Schedule 4 or the Settlement System Administrator shall be
          entitled to insist upon due and proper performance by the Executive
          Committee of its obligations under the SSA Arrangements.

7.3       Variations of Sole Supplier Services: The Executive Committee shall
          have the right to vary the volume of Service under any Sole Supplier
          Service to a level where no Service under the relevant Service Line is
          capable of being provided or can be Ordered. Exercise

<PAGE>

          of this right will not constitute a failure or deemed failure by the
          Executive Committee to comply with its obligations under the SSA
          Arrangements.

7.4       Review of Sole Supplier Index: Within a period of six months after
          each of 31st March, 1999 and 31st March, 2002 the Settlement System
          Administrator shall review the Sole Supplier Index in consultation
          with the Executive Committee to assess whether it is appropriate to
          amend or, as the case may be, further amend the list of Services which
          are designated as Sole Supplier Services. If as a result of either
          such review or at any other time the Settlement System Administrator
          and the Executive Committee shall agree to amend or substitute the
          list of Services in whole or in part, the Sole Supplier Index shall be
          revised accordingly.

8.        MANAGEMENT OF RESOURCES

The Settlement System Administrator shall manage and schedule its resources and
the resources available to it as it sees fit. Neither the Contract Manager nor
Pool Members shall be entitled to specify that particular individuals be
provided in relation to Services other than named project managers pursuant to
Service Line 16 (Management Services), but the Contract Manager and Pool Members
shall have the right to specify skill categories.

9.        MARKET TESTS

9.1       Market Tests: The Executive Committee shall have the right to carry
          out market tests of the price of Services in accordance with the
          following provisions of this Section.

9.2       Timing: Market tests shall be carried out at the request of the
          Executive Committee from time to time and shall be conducted by or on
          behalf of the Executive Committee.

9.3       Settlement System Administrator's involvement:

          (a)       If the Executive Committee wishes the Settlement System
                    Administrator to take account of a market test, then the
                    Executive Committee shall use its reasonable endeavours to
                    commission a market test on a "like for like" basis for the
                    provision of the Service in question (including as to
                    quality, timeliness and flexibility) from a supplier of
                    equal standing to the Settlement System Administrator agreed
                    between the Executive Committee and the Settlement System
                    Administrator (such agreement not to be unreasonably
                    withheld) and shall permit the Settlement System
                    Administrator to appraise the method and results of the
                    market test and to request clarification of the method and
                    clarification and correction of the results.

          (b)       If the market test shall result in an indication that the
                    Service in question may be obtained at a lower comparable
                    price from another supplier, the Settlement System
                    Administrator shall either demonstrate within a reasonable
                    time why it is

<PAGE>

                    unable to adopt the lower comparable price or accept the
                    results of the market test and forthwith adopt the lower
                    comparable price.

          (c)       If the Settlement System Administrator shall seek to
                    demonstrate why it is unable to adopt the lower comparable
                    price rather than accept the results of the market test but
                    the Executive Committee disputes that the Settlement System
                    Administrator either has done so within a reasonable time as
                    required by paragraph (b) above or has adequately
                    demonstrated why it is unable to adopt the lower comparable
                    price, and in either case should therefore accept the
                    results of the market test and adopt the lower comparable
                    price, the Executive Committee may refer the dispute to
                    arbitration in accordance with Clause 83.

10.       PERFORMANCE IMPROVEMENT PROGRAMMES

10.1      Performance Improvement Programmes: The Executive Committee and the
          Settlement System Administrator may from time to time agree to conduct
          programmes designed to improve the cost-effectiveness of the Services.
          All such programmes shall be conducted in accordance with the
          principles set out in the following provisions of this Section and the
          Settlement System Administrator shall be obliged to participate in all
          such programmes.

10.2      Close Co-operation: Performance Improvement Programmes shall require
          close co-operation and an exchange of information between the
          Executive Committee and the Settlement System Administrator to a
          greater degree than is contemplated elsewhere by the terms of this
          Agreement.

10.3      Cost-benefit Sharing: The purpose of a Performance Improvement
          Programme is to yield cost-benefit sharing and any such programme will
          involve an analysis of actual costs rather than the prices that are
          contained in the Menus of Prices.

10.4      Procedure: The procedure for conducting a Performance Improvement
          Programme is set out in the Contract Management Rules.

10.5      Costs of PIPs: The costs of all Performance Improvement Programmes
          shall be borne by Pool Members according to their respective
          Contributory Shares and shall be recovered in accordance with the
          Charging Procedure.

10.6      Division of Cost Savings: If a Performance Improvement Programme shall
          demonstrate a saving in all or any of the costs that are incurred by
          the Settlement System Administrator in providing the Services, then
          that saving shall be shared equally between the Settlement System
          Administrator on the one hand and Pool Members on the other hand at
          that time and in the manner agreed between the Account Manager and the
          Contract Manager from time to time provided that the Pool Members
          shall have the right to receive the entire benefit of that saving
          until such time as they have received in full

<PAGE>

          through that saving an amount equal to the costs incurred by them
          referred to in sub-section 10.5 above.

10.7      Cost Savings by Pool Members: If a Performance Improvement Programme
          shall demonstrate a saving in all or any of the costs that are
          incurred by Pool Members (other than costs payable to the Settlement
          System Administrator under the SSA Arrangements), the relevant Pool
          Members shall have the right to the entire benefit of that saving and
          shall not be required to share all or any part of that benefit.

10.8      Non-PIP Modifications: The following actions with regard to any
          Service provided by the Settlement System Administrator shall not be
          the subject of a Performance Improvement Programme and any cost
          savings caused by such action shall not be dealt with in accordance
          with the principles of the Performance Improvement Programmes:-

          (a)       a change in the volume and/or frequencies of any Service
                    under a Service Line within the maximum and minimum limits
                    stated for that Service in the relevant Menu of Prices;

          (b)       a change in the level of quality, fault tolerance or
                    security for a particular Service where the commercial
                    objectives (as stated in the relevant Service Lines) are not
                    amended in respect of that change;

          (c)       replacement of any Hardware or Software in the normal course
                    of business;

          (d)       where a Performance Improvement Programme is undertaken in
                    respect of one or more particular Service Lines, any
                    concomitant modification to a Service Line which is not the
                    subject of that particular Performance Improvement
                    Programme; and

          (e)       where the Settlement System Administrator discovers that,
                    through its own efforts, it has performed Services in a more
                    efficient manner than it originally planned.

11.       CONTRACT REPORTING

Reports: The Settlement System Administrator shall provide the Contract Manager
with reports in accordance with Service Line 10 (Service to CEO and Pool
Members).

                            PART C: NEW REQUIREMENTS

1.        CHANGES TO SERVICES

1.1       Changes to Services: Without prejudice to Parties' rights generally to
          amend this Agreement, the Contract Manager may from time to time
          request the Settlement System Administrator:-

          (a)       to provide a new Service; or

          (b)       to amend a Service currently included in a Service Line or
                    to amend a Non-Menu Service; or

          (c)       to delete a Service currently included in a Service Line.

          negotiate in good faith with the Contract Manager to amend in
          accordance with the Change Management Procedure, the applicable
          Service Line, Menu of Prices and Variation Menu (or, if the Service is
          a Non-Menu Service, to agree or amend documentation recording the
          terms and conditions on which the Non-Menu Service is to be provided)
          and, if necessary, to amend other elements of the SSA Arrangements to
          give effect to such request provided that:-

          (a)       neither the Settlement System Administrator nor the
                    Executive Committee nor Pool Members shall be obliged to
                    agree any such amendment or documentation; and

          (b)       there shall be no obligation on the Account Manager or the
                    Contract Manager to continue such negotiations if it is or
                    becomes evident that there is no agreement to provide the
                    Service or make the change referred to in sub-section 1.1
                    above or as to the amendments required to give effect to
                    such new Service or change.

          As part of the negotiations for the provision of a new or amended
          Service, the Account Manager shall provide the Contract Manager with
          (in the case of a new Service) a price for the Service together with a
          statement of the incremental (but not necessarily pro rata) resource
          requirement and an accompanying written explanation, and (in the case
          of an amended Service) a revised price for that Service justified by
          reference to the prices in the relevant Menu of Prices and accompanied
          by a written explanation.

1.3       Agreed Changes to Services: The SSA Arrangements, applicable Service
          Lines, Menus of Prices and Variation Menus (or, if a Non-Menu Service
          is affected, the documentation recording the terms and conditions on
          which the Non-Menu Service is to be provided) shall be amended as
          required to reflect any agreement between the Pool Members and the
          Settlement System Administrator to:-



                                       2
<PAGE>

          (a)       vary the SSA Arrangements, the Settlement System or the
                    Stage 1 Development Policies; or

          (b)       include an Ad Hoc Production Service as a Continuous
                    Production Service,

          in accordance, where appropriate, with the Contract Management Rules.

1.4       Formal documentation: Any new Service or change to Service referred to
          in sub-section 1.1 above shall take effect as from the date specified
          in the formal documentation giving effect to such new Service or
          change and in accordance with the terms of such documentation.

1.5       Addition to Sole Supplier Index: Where a new Service Line is created
          as part of the formal documentation giving effect to a new Service or
          change to a Service the Settlement System Administrator and the
          Executive Committee shall consider whether such new Service Line
          should be added to the Sole Supplier Index and, if they so agree, it
          shall be so added.

2.        PRICE ON REQUEST

2.1       Request for a price: The Contract Manager may from time to time
          request the Account Manager on behalf of the Settlement System
          Administrator to quote a price for any Price on Request Item and the
          Settlement System Administrator will within a reasonable time quote
          such a price.

2.2       Basis of the price: The price quoted by the Settlement System
          Administrator shall be calculated by taking account of the Menu of
          Prices for the category of Services which most closely corresponds to
          the relevant Price on Request Item and, if applicable, to the price
          payable for any third party resources for which the Settlement System
          Administrator will need to contract to provide such Price on Request
          Item.

2.3       Price on Request: The request and quotation procedure in sub-sections
          2.1 and 2.2 above is known as the Price on Request procedure.

2.4       Amendment Procedure: Upon receipt of the Settlement System
          Administrator's price the Contract Manager may (but shall not be
          obliged to) agree the price quoted. If the Contract Manager shall
          notify the Account Manager that he agrees the price, the Account
          Manager and the Contract Manager shall ordinarily amend the applicable
          Menu of Prices to include the quoted price and the applicable
          Variation Menu and, if necessary, the applicable Service Line to
          include more detail as to the Service to be provided, unless the
          Contract Manager and the Account Manager agree that the price of a
          Price on Request Item shall not be added to the applicable Menu of
          Prices in which case such Price on Request Item shall remain a Price
          on Request Item. Upon such amendment(s) being made the relevant Price
          on Request Item shall cease to be a Price on Request Item and


                                       3
<PAGE>

          shall become a Production Service, a Development Service or a
          Consultancy Service (as appropriate) which may then be Ordered.

          requisite period of notice of variation (if any) being given.

4.2       Limits: Menus of Prices may provide maximum and minimum limits of a
          particular Service. Services required in excess of any such maximum

          minimum shall, at the request of the Contract Manager, be provided at
          a revised lower price where determined in accordance with a
          Performance Improvement Programme.

          Parties for any of the consequences of such reliance.

4.6       General meetings: The Settlement System Administrator shall not be

          Members in general meeting or of any class of Pool Members in separate
          general meeting which it is advised by the Executive Committee or the
          Chief Executive as having been passed was in fact passed or passed by
          the requisite majority and until the Settlement System Administrator
          shall have express written notice to the contrary from the Executive
          Committee or the Chief Executive it shall be entitled to assume that
          the relevant resolution was passed or (as the case may be) the

          (b)       the Settlement System Administrator has reasonable grounds

                    (ii)      the Director has indicated that, notwithstanding
                              any such actual or potential breach, the Director
                              would not be minded to enforce compliance with
                              those obligations and the Settlement System
<PAGE>

                              Administrator has received an indemnity reasonably
                              satisfactory to it in respect of its acting in
                              accordance with such requests or Orders.

          In any such event the Settlement System Administrator shall promptly
          notify the Executive Committee.

4.8       Reference to the Director: If at any time the Settlement System
          Administrator has a concern which is properly and reasonably founded
          that, in acting in accordance with any requests of the Executive

          Order, it will breach one or more of NGC's obligations under the Act
          or NGC's Transmission Licence, then, if having discussed the matter
          with the Executive Committee the matter remains unresolved, the
          Settlement System Administrator shall either comply with such request
          or Order or by notice in writing refer the same to the Director, such
          notice to set out in full the request or be accompanied by a copy of
          the Order (as the case may be) given to the Settlement System
          Administrator and the grounds for such concern and to be copied to the
          Executive Committee and (if applicable) the individual Pool Member.
          Pending any guidance from the Director in response to any such
          reference and, provided that the Director shall not express any view
          that such reference is misconceived, vexatious or in respect of an
          improperly or unreasonably founded concern, the Settlement System
          Administrator shall not be liable to any of the other Parties for
          refusing to act in accordance with the relevant request or Order. If
          the Director shall express such a view, the Settlement System
          Administrator shall be so liable.

          give the Settlement System Administrator a Remediable Removal Notice

          Executive Committee pursuant to this sub-section, the provisions of
          sub-section 12.1 shall apply for each such Service Failure.

System Administrator in providing the Services and arising in any SSA Accounting
Period may be recovered by the Settlement System Administrator in any subsequent
SSA Accounting Period as if it were a Third Party Cost (but the Settlement
System Administrator shall not have the right to recover the Handling Charge in
respect thereof).

3.        NEW TAXES OR NEW LEGISLATION

3.1       New taxes: If by reason of the introduction of a new tax (other than a
          tax on overall net income) the cost to the Settlement System
          Administrator of providing the Services is increased or the amount of
          any payment received or receivable by the Settlement System
          Administrator under the SSA Arrangements for providing the Services is
          reduced, then:-

          (a)       forthwith upon becoming aware of the happening of such event
                    the Settlement System Administrator shall notify the
                    Executive Committee who shall thereupon notify the Pool
                    Members;

          (b)       the Settlement System Administrator shall, as soon as is
                    reasonably practicable, give the Executive Committee (who
                    shall thereupon notify the Pool Members) a certificate
                    giving details of the new tax and the amount of such
                    additional cost or reduction and the calculation thereof and
                    the period to which it applies together with a report from
                    its auditors confirming that they have reviewed the basis of
                    the calculation of the additional cost or reduction and
                    confirming the accuracy of the calculation; and

          (c)       subject to the Settlement System Administrator complying
                    with its obligations under paragraphs (a) and (b) above, the
                    Settlement System Administrator shall have the right to
                    recover from Pool Members the amount of such additional cost
                    or reduction through an adjustment to the Menus of Prices or
                    in such other manner as may be agreed with the Executive
                    Committee as will in either case ensure that the Settlement
                    System Administrator is kept whole in respect of such
                    additional cost or reduction.

3.2       New legislation: If at any time the Settlement System Administrator
          becomes subject to either a new statute passed by the government of
          the United Kingdom or a new European Union regulation which is
          directly applicable, in either case under which the

<PAGE>

          Settlement System Administrator is obliged to act in a manner which
          materially increases the cost to it of providing the Services then it
          shall notify the Executive Committee of such a change and if the
          Executive Committee is satisfied, in its sole discretion, that:-

          (a)       the Settlement System Administrator is obliged to act in
                    accordance with the new legislation; and

          (b)       the cost to the Settlement System Administrator of providing
                    the Services as a whole will be materially increased as a
                    result of complying with such legislation,

          the Executive Committee shall enter into good faith negotiations with
          the Settlement System Administrator to agree (but with no absolute
          obligation on the Executive Committee or the Settlement System
          Administrator to agree) amendments to the Menus of Prices to reflect
          such increased costs.

4.        EXCEPTIONAL ITEMS

If, where Service Line 21 (Emergency Services) is invoked by the Executive
Committee, the Settlement System Administrator shall necessarily incur
additional costs in running the Stage 1 Settlements Business during a Security
Period, those costs shall be regarded as beyond the control of the Settlement
System Administrator and the Settlement System Administrator may recover the
same, together with an administration charge of 2.5 per cent., as if they were
Third Party Costs (but shall not have the right to recover the Handling Charge
in respect thereof) provided that such costs have been verified as additional
costs by the Settlement System Administrator's auditors. Pool Members shall be
obliged to pay the actual amount of such costs and all reasonable costs of the
Settlement System Administrator's auditors in verifying the same.

5.        MARKET TEST COSTS

Where any market test is commissioned by the Executive Committee, Pool Members
shall be liable according to their Contributory Shares for:-

          (a)       all Third Party Costs (if any) incurred in contracting for
                    the market test services; and

          (b)       all costs (if any) directly and properly incurred by ESIS in
                    appraising the result of a market test of which the
                    Settlement System Administrator has been asked to take
                    account pursuant to sub-section 9.3 of Part B and in
                    requesting clarification of the method and clarification and
                    correction of the results thereof.

Settlement System Administrator for

<PAGE>

          Administrator shall send the Contract Manager an invoice statement for

<PAGE>

2.4       Content of Invoice Statement: Each invoice statement for Post Charges
          shall specify the amount due in respect of Services provided during
          the relevant month and not contained in the invoice statement for

                    Charge;

          (f)       any charges for Services provided during such month
                    requested by the Director or his staff under Service Line 9
                    (Service to the Director General of Electricity Supply);

          (g)       any charge for Services provided under Service Line 8
                    (Service to Pool Auditor) requested by the Pool Auditor; and

          the same, but shall not be precluded from raising any such concerns at
          any later stage. If any concerns are not settled by the date the
          invoices are required to be despatched to Pool Members, such invoices
          may be despatched by the Settlement System Administrator on the basis
          it reasonably believes to be correct insofar as they relate to Prior
          Charges or Post Charges which are not disputed by the Contract
          Manager. Any Prior Charges or Post Charges which are believed in good
          faith to be wrong by the Contract Manager and continue to be disputed
          in good faith may not be included in any invoice until the amount
          outstanding has been settled between the Settlement System
          Administrator and the Contract Manager. Where, after investigation, it
          is agreed between the Contract Manager and the Settlement System
          Administrator that the amount disputed has in fact been correctly
          calculated by the Settlement System Administrator, the Settlement
          System Administrator shall have the right to charge interest on such
          Prior Charges or Post Charges in accordance with and on the basis set
          out in sub-section 3.3 below from the date upon which they would have
          been due for

          send each Pool Member an invoice:-

          (a)       in respect of an invoice for Prior Charges, no later than
                    the first day of the month prior to the month in respect of
                    which the relevant charges are to be recovered; and

          (b)       in respect of an invoice for Post Charges, no later than ten
                    days after such statement is sent to the Contract Manager,

          in each case for an amount determined in accordance with Part K
          provided that where the aggregate amount of Post Charges in any month
          does not exceed (pound)100,000 the Settlement System Administrator may
          include such Post Charges in the next following invoice for Prior
          Charges issued subject to sub-section 2.6(a) above.

2.6A      Invoices for Suppliers' ERS Charges: No later than the fifth working
          day of each month, the Settlement System Administrator shall send to
          each Supplier an invoice determined in accordance with Part K in
          respect of:-

          (a)       the Supplier's ERS Variable Charge for that month,

                    purpose, to rely on information provided to it by the
                    Executive Committee); and

          (b)       the Supplier's ERS Fixed Charge for that month, calculated
                    as specified in Section 4 of Schedule 31 (the Settlement
                    System Administrator being entitled, for this purpose, to
                    rely on information provided to it by the Executive
                    Committee).

2.7       Resignation or removal of the Settlement System Administrator: Where
          the Settlement System Administrator resigns in accordance with Section
          14 of Schedule 4 or is removed in accordance with Section 17 of
          Schedule 4, the Settlement System Administrator shall be responsible
          for all Transition Costs. Accordingly:-

          (a)       Orders placed by Pool Members cannot be used to defray
                    Transition Costs; and

          (b)       the Settlement System Administrator shall not include any

          default up to but excluding the date of actual payment (after as well
          as before judgment) at the rate which is 4 per cent. per annum above
          the base rate from time to time during each period of default of
          National Westminster Bank plc.

3.4       Payment of charges: Each Pool Member shall pay its due proportion of

                                        terms and for such period(s) as it
                                        reasonably sees fit;

                    (v)       (A)       any Pool Member falling within

                    (vi)      the Executive Committee may from time to time
                              amend the categories of membership and the fees

                              Administrator, such consent not to be unreasonably
                              withheld or delayed);

                              in this paragraph (c) shall be adjusted in
                              relation to each Pool Member, Generator or
                              Supplier, as the case may be, by reference to the
                              number of days during each year for which such
                              Party was a Pool Member and (where appropriate)
                              the number of Generating Units or Metering Systems
                              allocated to it during such period; and

          (d)       fourthly, 100 per cent. of the balance of the Total Sum Due
                    during any month not recovered pursuant to paragraphs (a) to
                    (c) (inclusive) above shall be allocated amongst all Pool
                    Members during such month by reference to the Contributory
                    Shares of each Pool Member.

                    For this purpose:-

                    (i)       each Pool Member's due proportion of the charges
                              shall be assessed first by reference to the then
                              latest Contributory Shares of all Pool Members
                              calculated by the Executive Committee for the
                              period and each part thereof to which such charges
                              relate (or, if and to the extent that the charges
                              relate to a period for which no such calculation
                              has yet been made, by reference to the then most
                              recently calculated current Contributory Shares of
                              all Pool Members) and shall thereafter be
                              readjusted from time to time for each day within
                              the relevant period following changes to the
                              Contributory Shares of Pool Members for all or any
                              part of such period or (as the case may be)
                              following the calculation or (as the case may be)
                              re-calculation of the Contributory Shares for such
                              period; and

                    (ii)      in calculating any such readjustment from time to
                              time, the Total Sum Due shall, as between Pool
                              Members, be calculated in respect of any month
                              after September 1998 on the basis that the Total
                              Sum Due attributable to each month in an SSA
                              Accounting Period (or, in respect of the SSA
                              Accounting Period ending on 31st March, 1999, each
                              of the last six months of that SSA Accounting
                              Period) shall be equal and that the amount so
                              attributable to each such month shall accrue on a
                              daily basis.


<PAGE>

                    Provided that, in calculating the balance of the Total Sum
                    Due payable by each Pool Member in any month, the annual
                    membership fee payable by each Pool Member in accordance
                    with paragraph (c) above shall be divided by the number of
                    complete months in the SSA Accounting Period remaining after
                    the date of payment of such annual membership fee and the
                    resultant figure (after rounding to the nearest (pound)1)
                    shall be credited to the relevant Pool Member for offset
                    against its proportionate share of the Total Sum Due for
                    each such remaining month.

1.3       Prima facie evidence: The Settlement System Administrator's
          determination of the allocation of all costs during any month shall,
          in the absence of manifest error, be prima facie evidence thereof.

1.4       Contributory Shares: The Settlement System Administrator shall advise
          each Pool Member of its Contributory Share and how such Contributory
          Share is calculated.

1.5       Minimum payment: The Settlement System Administrator shall not issue
          any invoice, nor shall any Pool Member be required to pay any amount
          (whether by way of payment to the Settlement System Administrator or
          by way of adjustment), if the aggregate amount otherwise payable by
          that Pool Member pursuant to this Part is less than the minimum amount
          from time to time agreed by the Executive Committee with the
          Settlement System Administrator provided that if in respect of an SSA
          Accounting Period such aggregate amount is less than such minimum
          amount, the Settlement System Administrator shall issue an invoice in
          respect thereof (which the Pool Member shall be required to pay)
          immediately after the Final Calculation Date for the Accounting Period
          correlating to the SSA Accounting Period in question. Where the
          minimum applies, a Pool Member shall remain liable for any amounts
          payable by it but shall not be required to make any such payment until
          such time as the amount in question is permitted to be, and is,
          included in an invoice. Sub-section 3.3 of Part J shall be construed
          accordingly.

          other than in accordance with the terms hereof.

6.        FEES

          The Settlement System Administrator will pay the Custodian's fees as
          detailed in Schedule C as amended from time to time by written
          agreement between the parties. Such fees shall be invoiced monthly and
          paid within one month of the date of the invoice.

7.        TERMINATION

7.1       This Agreement shall terminate upon the release of the copy of the

7.3       This Agreement may be terminated by the Settlement System
          Administrator giving not less than 90 days' written notice to the
          Custodian provided that it may not terminate this Agreement without

<PAGE>

          unless it has been removed or has resigned as Settlement System
          Administrator and has complied with its obligations relevant to the
          Material under Clauses 28.1.1 and 28.1.4 of the Pooling and Settlement
          Agreement.

          instructed to the contrary by the Settlement System Administrator and
          the Executive Committee).

7.5       Termination of this Agreement for whatever reason will not relieve the

          5.

8.        TESTS

          The Executive Committee shall be entitled to require the Custodian to
          carry out such tests in the presence of the Settlement System
          Administrator which in the reasonable opinion of the Custodian would
          reasonably establish that the Material and Modifications contain true
          and accurate versions of the source codes and load (machine
          executable) modules in use at the time of testing in the settlement
          process. Any reasonable charges and expenses incurred by the Custodian
          in carrying out such tests will be paid by the Settlement System
          Administrator.

9.        OBSOLETE MATERIAL AND MODIFICATIONS

9.1       The Executive Committee shall be entitled to review from time to time
          the Material and Modifications on deposit with the Custodian. Where
          the Executive Committee is satisfied that any part of the Material or
          Modifications on deposit has ceased to be used in the settlement
          process and will be of no further use, whether directly or indirectly,
          it may request the Custodian to release any such part to the then
          current Settlement System Administrator. Such request shall be in
          writing and identify the part or parts of the Material or
          Modifications to be released by the Custodian and state that the
          reason for such release is that such part or parts is or are no longer
          of use. The Custodian shall release such part or parts to the then
          current Settlement System Administrator as soon as conveniently
          possible after receipt of any such written request from the Executive
          Committee.

9.2       Notwithstanding the release of any part or parts of the Material or
          Modifications to the Settlement System Administrator pursuant to
          Clause 9.1, in the event that any such released Material or
          Modifications or copies thereof are subsequently used in the
          settlement process such Material or Modifications shall be placed on
          deposit and held in escrow pursuant to this Agreement on the same
          terms and conditions as any Modification.

4.        LIMITATION OF LIABILITY

4.1       The total aggregate liability of the Performance Assurance Board and
          the Performance Assurance Administrator to an Interested Person
          whether in contract, tort (including negligence or breach of statutory
          duty) or otherwise arising directly or indirectly out of or in
          connection with the performance or non-performance of its functions
          (including the contents of any opinion or report prepared by the
          Performance Assurance Board or the Performance Assurance
          Administrator) shall in no circumstances exceed (pound)1,000,000 per
          claim or series of related claims.

4.2       Neither the Performance Assurance Board nor the Performance Assurance
          Administrator shall be liable to any Interested Person for any loss of
          profit, loss of revenue, loss of contract, loss of goodwill or any
          indirect or consequential loss arising out of or in connection with
          the performance or non-performance of its functions.

4.3       Sub-sections 4.1 and 4.2 shall not exclude the liability of the

4.4       The exclusions from and limitations of liability of the Performance

          negligence of the relevant one of the Performance Assurance Board or
          the Performance Assurance Administrator.

4.5       The exclusions from and limitations of liability of the Performance
          Assurance Board and the Performance Assurance Administrator under this
          Section are reasonable because of (amongst other matters) the
          likelihood that the amount of damages awardable to the Interested
          Person from the Performance Assurance Board or the Performance
          Assurance Administrator would otherwise be disproportionate to the
          charges which it makes in connection with the performance of its
          functions and because of the limited resources and expertise of the
          Performance Assurance Board and the Performance Assurance
          Administrator.


<PAGE>

4.6       The exclusions from and limitations of liability of the Performance
          Assurance Board and the Performance Assurance Administrator under this
          Section shall be considered severally and the invalidity or
          unenforceability of any one sub-section shall not affect the validity
          or enforceability of any other sub-section.

                       PART 5 : DISAPPLICATION PROVISIONS

5.        DISAPPLICATION

                             Billing and Settlement

                               PART 1: PRELIMINARY

1.        INTRODUCTION

1.1       Interpretation:

          1.1.1     In this Schedule, except where the context otherwise
                    requires, references to a particular Annex, Part, Section,
                    sub-section, paragraph or sub-paragraph shall be a reference
                    to that Annex to or Part of this Schedule or, as the case
                    may be, that Section, sub-section, paragraph or
                    sub-paragraph in this Schedule.

          1.1.2     In this Schedule references to any amount being exclusive or
                    inclusive of United Kingdom Value Added Tax shall mean that
                    that amount is exclusive or inclusive (as the case may be)
                    of a sum equal to such amount, if any, of United Kingdom
                    Value Added Tax as is properly chargeable on the supply to
                    which the first-mentioned amount is attributable as being
                    all or part of the consideration for that supply.

1.2       Banking and billing procedures:

          1.2.1     The banking and billing procedures set out in this Schedule
                    provide an administratively convenient method of arranging
                    financial settlement on a Settlement Day basis between Pool
                    Members, the Ancillary Services Provider and the Grid
                    Operator in respect of sales and purchases of electricity
                    under this Agreement, the provision of Ancillary Services
                    and sums payable by the Grid Operator in relation to
                    Transport Uplift. The Parties are content for these banking
                    and billing procedures to be used in the ordinary course of
                    electricity trading under this Agreement.

          1.2.2     The Parties acknowledge however that using the banking and
                    billing procedures set out in this Schedule will not in all
                    circumstances result in the payments required to be made
                    between Pool Members, the Ancillary Services Provider and
                    the Grid Operator (or some of them) being the same as those
                    that would result from the strict application of the Pool
                    Rules (and, in particular, sub-section 24.8 of Schedule 9).

          1.2.3     The Parties further acknowledge the provisions of Clause 6.8
                    (which provide for the Pool Rules to prevail over the other
                    provisions of this Agreement in the event of any
                    inconsistency or conflict) and irrevocably and
                    unconditionally authorise the Pool Funds Administrator to
                    issue accounts from time to time when instructed to do so by
                    the Executive Committee (but subject to the Pool Funds
                    Administrator having received the information requested
                    under sub-section 7.1 so as to enable it to issue such
                    accounts) to Pool Members, the Ancillary Services Provider
                    and the Grid Operator providing for payments to be made
                    between


<PAGE>

                    them (or some of them) to correct any imbalances between
                    amounts paid and received (or payable and receivable)
                    pursuant to the operation of the banking, billing and
                    payment default procedures set out in this Schedule and the
                    amounts that would have been due between them had the Pool
                    Rules been strictly applied (and, in particular, had claims
                    been identified and settled in accordance with sub-section
                    24.8 of Schedule 9).

          5.3.1     the extent of each Pool Creditor's individual rights shall
                    be deemed to consist of the aggregate of the claims (to the
                    extent not paid or otherwise satisfied) of such Pool
                    Creditor in respect of each Settlement Period; and

          5.3.2     the assets referred to in paragraph 5.1.1 shall be deemed to
                    consist of a series of funds, each fund representing the
                    rights or moneys owed, paid, held or otherwise attributable
                    to each Settlement Period. The Pool Funds Administrator
                    shall not be obliged to segregate moneys into separate
                    funds.

5.4       Rights of Ancillary Services Provider: The rights of the Ancillary
          Services Provider to assets held on trust shall be determined in
          accordance with Section 23 of Schedule 9.

5.5       Trusts in respect of Pool Reserve Assets: The Pool Funds Administrator
          shall stand possessed of the Pool Reserve Assets on the following
          trusts, that is to say:-

          5.5.1     at any time when no amounts owed by Pool Debtors are
                    overdue, on trust to repay (subject to and in accordance
                    with the provisions of sub-sections 5.8 and 5.9) to each
                    Providing Member and the Grid Operator the respective share
                    of such Providing Member or (as the case may be) the Grid
                    Operator (determined in accordance with sub-section 5.13) of
                    the Pool Reserve Assets; and

          5.5.2     with automatic effect as soon as any amount owed by a Pool
                    Debtor becomes overdue, to hold an amount of the moneys
                    credited from time to time to the Pool Reserve Account equal
                    to the Notified Payment Shortfall or the amount held in the
                    Pool Reserve Account attributable to such Pool Debtor
                    (whichever is less) on the trusts set out in paragraph 5.1.1
                    and the balance (if any) shall be held on the trusts set out
                    in paragraph 5.5.1.

5.6       Overdue amounts: In respect of a Pool Debtor and for the purposes of
          sub-section 5.5, an amount shall be deemed to become overdue at the
          time at which the Pool Funds Administrator becomes aware that such
          Pool Debtor has not made or will not make by 12.30 hours payment in
          full to the credit of the Collection Account of such Pool Debtor of
          such an amount as it is required on such day to make and, for as long
          as the Credit Facility remains unconditionally available, the Pool
          Funds Administrator considers in good faith that the amount in default
          is not likely to be remedied on the next Business Day.

5.7       Notified Payment Shortfall: The term "Notified Payment Shortfall"
          means the amount from time to time of Notified Payments which have
          become overdue by application of the rule set out in sub-section 5.6
          and which have not subsequently been paid (whether by


<PAGE>

          remittance from a Pool Debtor, payment out of the Pool Reserve Account
          or a call under a Letter of Credit). To the extent that the Pool Funds
          Administrator is unable to determine the precise amount of a Notified
          Payment Shortfall, it shall be deemed to be such amount as the Pool
          Funds Administrator and the Pool Banker shall agree or, failing
          agreement, the entire amount of the Notified Payment.

5.8       Providing Members' and the Grid Operator's rights to funds:

          5.8.1     Each Providing Member and the Grid Operator remitting funds
                    for credit to the Pool Reserve Account agrees that the
                    following terms shall apply. None of the remittances shall
                    be repayable until a Providing Member has ceased to be a
                    Pool Member or (as the case may be) the Grid Operator has
                    ceased to be a Party and has paid in full all amounts
                    actually or contingently owed by it to any Pool Creditor,
                    the Settlement System Administrator or the Pool Funds
                    Administrator pursuant to this Schedule.

          5.8.2     Furthermore, if and to the extent that, at any time when an
                    amount would be repayable to a Providing Member or the Grid
                    Operator pursuant to this sub-section 5.8, all or any part
                    of the Providing Member's or the Grid Operator's interest in
                    the Pool Reserve Assets is represented by a loan to a Pool
                    Member or the Grid Operator deemed to be made in accordance
                    with paragraph 21.1.3 or 21.1.5, the rights of a Providing
                    Member or (as the case may be) the Grid Operator as against
                    the Pool Funds Administrator to receive a payment of its
                    share in the Pool Reserve Assets (or the relevant portion of
                    such share) shall be conditional on repayment in full of the
                    relevant loan.

          purported notice of withdrawal not complying with this sub-section
          5.9.

5.10      Providing Members' and Grid Operator's rights to withdraw funds:
          Notwithstanding sub-sections 5.8 and 5.9, if a Providing Member or (as
          the case may be) the Grid Operator is not in default in respect of any
          amount owed to a Pool Creditor:-

          5.10.1    the Pool Funds Administrator shall transfer to the relevant
                    Providing Member or the Grid Operator quarterly its share of
                    interest credited to the Pool Reserve Account; and

          5.10.2    the Pool Funds Administrator shall transfer to such
                    Providing Member or the Grid Operator within a reasonable
                    time after a written request of such Providing Member or (as
                    the case may be) the Grid Operator therefor any amount of
                    cash which exceeds the amount which such Providing Member or
<PAGE>

                    the Grid Operator is required to maintain in the Pool
                    Reserve Account from time to time in accordance with Section

5.11      Waiver of Providing Members' and Grid Operator's rights: Each
          Providing Member and the Grid Operator waives any right it might

          5.12.1    amounts from time to time credited to the Pool Reserve
                    Account;

          5.12.2    amounts which any Providing Member or the Grid Operator is
                    from time to time obliged to pay to the Pool Funds
                    Administrator for credit to the Pool Reserve Account and
                    claims in respect of such amounts;

          5.12.3    interest accrued and accruing on the Pool Reserve Account;

          5.12.4    any amounts credited to the Pool Reserve Account pursuant to
                    paragraph 15.4.3; and

          5.12.5    any loans deemed to be made from any amounts credited to the
                    Pool Reserve Account pursuant to paragraph 21.1.3 or 21.1.5.

5.13      Providing Members' and Grid Operator's rights and interests in the
          Pool Reserve Account: At any time when it is necessary to determine
          the respective rights and interests of Providing Members and the Grid
          Operator in and to funds standing to the credit of the Pool Reserve
          Account, such rights shall be determined in accordance with the
          following rules:-

          5.13.1    any amount withdrawn from the Pool Reserve Account following
                    the occurrence of a Notified Payment Shortfall which the
                    Pool Funds Administrator has determined to be attributable
                    to a particular Providing Member or (as the case may be) the
                    Grid Operator (the "Relevant Provider") (irrespective of the
                    existence or otherwise of actual fault on the part of the
                    Relevant Provider) shall in the first instance reduce pro
                    tanto the Relevant Provider's interest in the Pool Reserve
                    Assets;

          5.13.2    if, in any circumstances described in paragraph 5.13.1, the
                    Notified Payment Shortfall exceeds the Relevant Provider's
                    interest in the Pool Reserve Account, then any excess
                    required to be withdrawn from the Pool Reserve Account shall
                    reduce the respective interests of Providing Members and the
                    Grid Operator,


<PAGE>

                    other than the Relevant Provider, in proportion to their
                    respective interests in the Pool Reserve Account prior to
                    the withdrawal;

          5.13.3    any proceeds of a Letter of Credit which are to be credited
                    to the Pool Reserve Account pursuant to sub-section 5.16,
                    and any amounts paid by a Relevant Provider to make up a
                    payment out of the Pool Reserve Account, shall be applied in
                    priority in or towards reinstating (rateably among
                    themselves) the respective interests of Providing Members
                    and the Grid Operator other than the Relevant Provider in
                    the Pool Reserve Account;

          5.13.4    subject to the rules set out in paragraphs 5.13.1 to 5.13.3
                    (inclusive), the respective rights of each Providing Member
                    and the Grid Operator in and to funds standing to the credit
                    of the Pool Reserve Account shall be to receive (subject to
                    sub-sections 5.8 and 5.9) an amount equal to the aggregate
                    amounts remitted by the Providing Member and the Grid
                    Operator to the Pool Reserve Account and not subsequently
                    withdrawn, together with a proportionate share of any
                    interest from time to time credited to the Pool Reserve
                    Account; and

          5.13.5    in the absence of a Notified Payment Shortfall, any amounts
                    credited to the Pool Reserve Account following a call under
                    a Letter of Credit pursuant to sub-section 15.5 shall be
                    considered as an interest in the Pool Reserve Assets of the
                    Relevant Provider in respect of the relevant Letter of
                    Credit.

5.14      Overpayments to be held on trust:

          5.14.1    If and to the extent that payments under this Schedule
                    actually made on any day by the Pool Funds Administrator to
                    Pool Members or the Ancillary Services Provider in respect
                    of supplies of electricity under this Agreement or the
                    provision of Ancillary Services do not correspond exactly
                    with their respective payment entitlements established in
                    accordance with this Schedule in relation to supplies of
                    electricity or the provision of Ancillary Services in
                    respect of that same day, then the person receiving any
                    overpayment shall receive and be deemed to hold the amount
                    of such overpayment on trust for the Pool Member or rateably
                    for the Pool Members, the Ancillary Services Provider or (as
                    the case may be) for the Grid Operator which, in respect of
                    that same day was (were) underpaid (and, if none of them was
                    in fact underpaid, for the person(s) who overpaid the
                    amount).

          5.14.2    The person receiving any overpayment shall, on the written
                    instruction of the Pool Funds Administrator, pay the amount
                    of such overpayment to the Pool Funds Administrator for
                    redistribution.
<PAGE>

5.15      Reimbursement of overpayments: Subject to sub-sections 5.8 and 5.14,
          all payments under this Schedule shall be made on the basis that a
          Pool Member or the Grid Operator shall only be entitled to claim
          reimbursement of an overpayment made by it (whether to the Pool Funds
          Administrator or (through the Pool Funds Administrator) to another
          Pool Member, the Ancillary Services Provider or the Grid Operator) if,
          and then only to the extent that:-

          (a)       the aggregate amounts paid by the Pool Member or (as the
                    case may be) the Grid Operator in respect of the relevant
                    Payment Date

          exceed

          (b)       the total amounts payable by that Pool Member or (as the
                    case may be) the Grid Operator to Pool Creditors in respect
                    of that Payment Date together with all amounts (if any)
                    overdue by that Pool Member or (as the case may be) the Grid
                    Operator in respect of periods prior to the relevant Payment
                    Date.

5.16      Repayment of loans: Notwithstanding their rights pursuant to paragraph
          5.1.1 in and to Letters of Credit and the proceeds thereof, Pool
          Creditors agree that if:-

          5.16.1    a payment is received under a Letter of Credit after a sum
                    has been withdrawn from the Pool Reserve Account to make
                    good (in whole or in part) a discrepancy between amounts
                    owed and amounts received by the due time on a particular
                    Payment Date; and

          5.16.2    the aggregate of the amounts paid out of the Pool Reserve
                    Account and paid under the Letter of Credit exceeds the
                    amounts owed in respect of the relevant Payment Date,

          then any excess paid under the Letter of Credit over the amount then
          remaining unpaid in respect of the relevant Payment Date shall be
          credited to the Pool Reserve Account. Where appropriate, any such
          credit shall pro tanto constitute repayment of any loans deemed to be
          made pursuant to paragraph 21.1.3 or 21.1.5.

5.17      No claim for breach of trust: Provided that the Pool Funds
          Administrator carries out its duties under this Agreement, none of the
          Pool Members, Ancillary Services Provider nor the Grid Operator shall
          have any claim against the Pool Funds Administrator for breach of
          trust or fiduciary duty arising solely out of any discrepancy between
          payments actually made in respect of any day and the entitlement of
          Pool Members, Ancillary Services Provider or the Grid Operator under
          this Schedule to receive payments in respect of that same day.

                                        initial period of not less than 12
                                        months); and

                              (ii)      cash for credit to the Pool Reserve
                                        Account,

                              in both cases in such amount as shall be notified
                              by the Executive Committee in accordance with
                              Section 16;

          15.1.3    each Providing Member and the Grid Operator mentioned in
                    paragraph 15.1.1 to which paragraph (b) of paragraph 15.1.1
                    applies and (if paragraph (b) of paragraph 15.1.1 applies to
                    it) the Grid Operator shall immediately be required (in
                    addition to its obligations, if any, under paragraph 15.1.2)
                    to deliver to the Pool Funds Administrator a Letter of
                    Credit (available for an initial period of not less than 12
                    months) or cash for credit to the Pool Reserve Account in
                    such amount and in such proportions as shall be notified by
                    the Executive Committee in accordance with Section 16.

15.2      Letters of Credit: For the avoidance of doubt nothing in sub-section
          15.1 or 15.6 shall prevent any Providing Member or the Grid Operator
          from delivering a single Letter of Credit in respect of its
          obligations under paragraphs 15.1.2 and 15.1.3.

15.3      Cash deposit: Any cash amount delivered to the Pool Funds
          Administrator for credit to the Pool Reserve Account shall be held on

15.4      Maintenance of Security Cover: Each Providing Member and the Grid
          Operator shall be required to provide and at all times thereafter
          maintain a Security Amount equal to or more than the Security Cover
          applicable to it in such aggregate amount as shall be set from time to
          time in accordance with this Part 3. Immediately upon any reduction
          occurring in the Security Amount provided by any Providing Member or
          the Grid Operator or any Letter of Credit being for any reason drawn
          down (and including the deemed making of any loan to that Providing
          Member or the Grid Operator under the provisions of paragraph 21.1.3
          or 21.1.5) the Providing Member or (as the case may be) the Grid
          Operator will procure that new Letters of Credit are issued or
          existing Letters of Credit are reinstated (to the satisfaction of the
          Pool Funds Administrator) to their full value or that cash is placed
          to the credit of the Pool Reserve Account in an amount required to
          restore the Security Amount to an amount at least equal to the
          Security Cover applicable to the Providing Member or (as the case may
          be) the Grid Operator and in such proportions of Letters of Credit and
          cash as this Part 3 requires. Not later than 10 Business Days before
          any outstanding Letter of Credit is due to expire, the Providing

<PAGE>

          Member or the Grid Operator providing such Letter of Credit shall
          procure to the satisfaction of the Pool Funds Administrator that its
          required Security Amount will be available for a further period of not
          less than 12 months which may be done in one of the following ways:-

          15.4.1    (subject to the issuing bank continuing to have the credit
                    rating referred to in sub-section 15.6) provide the Pool
                    Funds Administrator with confirmation from the issuing bank
                    that the validity of the Letter of Credit has been extended
                    for a period of not less than 12 months on the same terms
                    and otherwise for such amount as is required by this Part 3;
                    or

          15.4.2    provide the Pool Funds Administrator with a new Letter of
                    Credit issued by an issuing bank with the credit rating
                    required by this Schedule for an amount at least equal to
                    the required Security Amount applicable to it (less its
                    balance on the Pool Reserve Account) which Letter of Credit
                    shall be available for a period of not less than 12 months;
                    or

          15.4.3    procure such transfer to the Pool Funds Administrator for
                    credit to the Pool Reserve Account as shall ensure that the
                    credit balance applicable to it standing to the credit of
                    the Pool Reserve Account shall be at least equal to the
                    required Security Amount.

15.5      Failure to supply Security Cover: If a Providing Member or the Grid
          Operator fails at any time to provide Security Cover to the
          satisfaction of the Pool Funds Administrator in accordance with the
          provisions of this Section 15, the Pool Funds Administrator may at any
          time while such default continues, and if at such time any Letter of
          Credit forming part of the Security Cover is due to expire within nine
          Business Days it shall immediately, and without notice to such
          Providing Member or (as the case may be) the Grid Operator, demand
          payment of the entire amount of any outstanding Letter of Credit and
          shall credit the proceeds of the Letter of Credit to the Pool Reserve
          Account to be held on the terms and on the trusts set out in Section
          5.

15.6      Substitute Letter of Credit: If the bank issuing the Letter of Credit
          of any Providing Member or the Grid Operator ceases to have the credit
          rating as is set out in the definition in Part I of this Agreement of
          "Letter of Credit", such Providing Member or (as the case may be) the
          Grid Operator shall forthwith procure the issue of a substitute Letter
          of Credit by a bank that has such credit rating.

16.       CREDIT MONITORING

16.1      Determination of Security Cover: The amount of Security Cover which
          each Providing Member and the Grid Operator shall be required to
          maintain and, in respect of the amounts of Security Cover to be
          provided under paragraph 15.1.2 (so long as applicable) and paragraph
          15.1.3 the proportions as between cash and Letter of Credit that may
          be


<PAGE>

          permitted, shall be determined from time to time by the Executive
          Committee in consultation with the Pool Funds Administrator in
          accordance with this Section 16 and on the basis of the criteria set
          out in sub-section 16.2, and shall be notified to such Providing
          Member or (as the case may be) the Grid Operator, and to the Pool
          Funds Administrator.

16.2      Criteria for provision of Security Cover:

          16.2.1    If paragraph (b) of paragraph 15.1.1 applies to a Providing
                    Member or the Grid Operator, the amount of Security Cover
                    required to be provided by such Providing Member or (as the
                    case may be) the Grid Operator in addition to the amounts
                    referred to in paragraph 15.1.2 (so long as applicable)
                    shall be provided by Letter of Credit in an amount to be
                    assessed by the Executive Committee in consultation with the
                    Pool Funds Administrator as the aggregate amounts payable
                    pursuant to this Agreement by the relevant Providing Member
                    or (as the case may be) the Grid Operator in respect of
                    purchases of, or as the case may be, prospective purchases
                    of electricity (including Ancillary Services) made by the
                    relevant Providing Member or in respect of sums payable in
                    accordance with Clause 49 of this Agreement by the Grid
                    Operator over a 28 day period, as determined by the
                    Executive Committee provided that with the approval of the
                    Executive Committee, all or part of the required Security
                    Cover may be provided in cash credited to the Pool Reserve
                    Account.

          16.2.2    In respect of all Providing Members and the Grid Operator,
                    the amounts required to be provided by each of them which
                    are referred to in paragraph 15.1.2 (so long as applicable)
                    shall (subject as provided in sub-section 21.12 and Section
                    25) be initially as to a minimum of 20 per cent. in cash and
                    the remainder by way of Letter of Credit, and thereafter as
                    revised by the Executive Committee. Such amounts shall be
                    assessed by the Executive Committee in consultation with the
                    Pool Funds Administrator to cover banking error and to
                    minimise reductions of payments to Pool Creditors.

16.3      Six monthly variation: In respect of paragraphs 16.2.1 and 16.2.2, the
          Executive Committee shall calculate two amounts for the two six-month
          periods commencing 1st April and 1st October in each year and shall
          advise the Pool Funds Administrator and the relevant Providing Members
          or (as the case may be) the Grid Operator accordingly. Such six
          monthly variation shall not apply to paragraph 16.2.2 where Section 25
          is applicable.

16.4      Review of Security Cover: The Pool Funds Administrator shall keep
          under review the Security Amounts relating to each Providing Member
          and the Grid Operator and shall promptly advise the Executive
          Committee, the relevant Providing Member or (as the case may be) the
          Grid Operator whenever the Security Cover maintained by such Providing

<PAGE>

          Member or (as the case may be) the Grid Operator is significantly more
          or less than the amount required to be maintained pursuant to this
          Part 3.

16.5      Increase or Decrease of Security Cover: If, after considering the
          recommendations of the Pool Funds Administrator and any
          representations which may be made by the relevant Providing Member or
          (as the case may be) the Grid Operator, the Executive Committee
          determines that the Security Cover of a Providing Member or the Grid
          Operator should be increased or decreased, it shall so notify the
          Providing Member or the Grid Operator (as the case may be), the Pool
          Funds Administrator and the Director. If the Executive Committee
          determines that such Security Cover should be decreased, the Providing
          Member or (as the case may be) the Grid Operator consents and the
          Director so approves, that reduction shall take place. The Pool Funds
          Administrator shall consent to an appropriate reduction in the
          available amount of any outstanding Letter of Credit and/or shall
          repay to the Providing Member or (as the case may be) the Grid
          Operator such part of the deposit held in the Pool Reserve Account for
          the account of such Providing Member or the Grid Operator (together
          with all accrued interest on the part to be repaid) sufficient to
          reduce the Providing Member's or Grid Operator's Security Amount to
          the level of Security Cover applicable to it. If the Executive
          Committee determines that the Providing Member's or the Grid
          Operator's Security Cover should be increased, the relevant Providing
          Member or (as the case may be) the Grid Operator shall, within five
          Business Days of notice as aforesaid, procure an additional or
          replacement Letter of Credit or transfer to the Pool Funds
          Administrator a cash deposit for credit to the Pool Reserve 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.

16.6      Notification in respect of Security Cover: The Pool Funds
          Administrator shall notify the Executive Committee, the Settlement
          System Administrator and the Director promptly if:-

          16.6.1    a Providing Member or the Grid Operator fails to provide,
                    extend or renew a Letter of Credit which it is required to
                    maintain pursuant to Section 15; or

          16.6.2    the Pool Funds Administrator shall make a call under any
                    such Letter of Credit; or

          16.6.3    the Pool Funds Administrator becomes aware that a Providing
                    Member or the Grid Operator (a) shall cease to retain 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 Providing Member or the Grid Operator retaining
                    an Approved Credit Rating, or (c) shall be in default under
                    the additional or alternative security referred to in
                    paragraph 15.1.1; or

<PAGE>

          16.6.4    the Security Amount in relation to any Providing Member or
                    the Grid Operator is at any time less than the level of its
                    required Security Cover for the time being; or

          16.6.5    the Pool Funds Administrator becomes aware that any bank
                    that has issued a Letter of Credit which has not expired
                    ceases to have the credit rating required by this Schedule.

16.7      Release from Security Cover obligations: A Providing Member or (as the
          case may be) the Grid Operator shall be released from its obligation
          to maintain Security Cover, and the Pool Funds Administrator shall
          consent to the revocation of any outstanding Letter of Credit, upon:-

          16.7.1    the Providing Member or the Grid Operator (as the case may
                    be) ceasing to be a Party;

          16.7.2    all its accrued liabilities under this Agreement having been
                    discharged; and

          16.7.3    all its liabilities under this Agreement which may accrue in
                    relation to the period during which it was a Party
                    (including amounts payable by it as a result of a Final
                    Reconciliation Run for any Settlement Day which falls during
                    that period), the Funds Transfer Agreement and any agreement
                    referred to in Clause 8.8.1(c), having been discharged.

16.8      No liability for amount of Security Cover: Any recommendations made by
          the Pool Funds Administrator pursuant to this Section 16 shall be
          given in good faith. Any instructions given by the Executive Committee
          in respect of the amount of Security Cover to be maintained by a
          Providing Member or the Grid Operator if given in good faith shall,
          insofar as applicable in terms of this Schedule, be binding on all
          Pool Members, the Ancillary Services Provider and the Grid Operator
          and neither the Pool Funds Administrator nor any Committee Member
          shall incur any liability by reason of the Security Cover of a
          Providing Member or the Grid Operator proving to be inadequate or
          excessive.

                    (b)       the corresponding amount shown to be payable by

                              Settlement Run for the same Settlement Day or, if
                              a Timetabled Reconciliation Run has already been
                              delivered in respect of that Settlement Day, in
                              the most recent Timetabled Reconciliation Run
                              previously delivered for that Settlement Day.

          17.6A.2   On the basis of the calculations made pursuant to paragraph
                    17.6A.1, the Pool Funds Administrator shall calculate in
                    respect of each Pool Member the aggregate of the additional
                    amounts (if any) shown to be payable by it or (as the case
                    may be) payable to it by way of adjustment in respect of
                    purchases of electricity for the relevant Settlement Day.

17.7      Deemed Reconciliation: Unless the Pool Funds Administrator shall, by
          close of business on the Notification Date or (as the case may be) on

          Notification Date), each Pool Member, the Ancillary Services Provider
          and the Grid Operator to the contrary, the information provided by the

          17.8.1    If the Pool Funds Administrator determines that the
                    information provided by the Settlement System Administrator

                    reconciled in accordance with sub-section 17.6, it shall as
                    soon as possible notify the Settlement System Administrator
                    or (as the case may be) the Initial Settlement and
                    Reconciliation Agent and (in either case) each Pool Member,
                    the Ancillary Services Provider and the Grid Operator
                    accordingly and require the Settlement System Administrator
                    or (as the case may be) the Initial Settlement and
                    Reconciliation Agent to correct any errors and obtain the
                    Pool Funds Administrator's reconciliation of the corrected
                    information as quickly as possible.

          17.8.2    As soon as the Pool Funds Administrator determines that the
                    information provided by the Settlement System Administrator
                    or (as the case may be) the Initial Settlement and
                    Reconciliation Agent can be reconciled in accordance with
                    sub-section 17.6, the Pool Funds Administrator shall notify
                    the Settlement System Administrator or (as the case may be)
                    the Initial Settlement and Reconciliation Agent and (in
                    either case) each Pool Member, the Ancillary Services
                    Provider and the Grid Operator of the reconciled information
                    required to be given pursuant to sub-section 17.6.

          17.8.3    Where the discrepancy lies with information originally
                    provided by the Settlement System Administrator, the
                    Settlement System Administrator shall

                    Administrator to carry out and issue the reconciliation.

                    provided by the Initial Settlement and Reconciliation Agent,
                    the Initial Settlement and Reconciliation Agent shall use
                    its best endeavours to provide such corrected information as
                    may be necessary for the Pool Funds Administrator to carry
                    out and issue the reconciliation.

                              relevant Pool Creditors in the proportion which

                              information as aforesaid bears to the amounts
                              which are so shown as due to all of them;

                              be ignored and such adjustment made as the Pool

                              be ignored and such adjustment made as the Pool
                              Funds Administrator considers appropriate).

          17.9.2    If payments are made in the circumstances set out in
                    paragraph 17.9.1(b), (c) or (d), the Settlement System
                    Administrator in conjunction with the Pool Funds
                    Administrator and (if applicable) the Initial Settlement and
                    Reconciliation Agent shall, as soon as actual reconciliation
                    can thereafter be made, make such adjustments as may be
                    necessary (and, where relevant, apply interest at the Base
                    Rate or at such other rate as shall be set from time to time
                    by the Executive Committee) to account for any differences
                    between payments made and actual reconciled payment
                    information.

          17.9.3    The amounts to be incorporated in the Advice Notes in
                    accordance with sub-section 18.1 (and in all cases together
                    with United Kingdom Value Added Tax thereon) as a result of
                    the calculations to be made in accordance with sub-section
                    17.6A shall be the amounts (if any) determined pursuant to
                    that sub-section to be payable by each Pool Member on that
                    Reconciliation Payment Date, together with such adjustments
                    as may be necessary (which shall include interest accrued as
                    specified in sub-section 17.10 at the Base Rate or at such
                    other rate as shall be set from time to time by the
                    Executive Committee) to account for the difference between
                    amounts previously paid by Pool Members and those payable on
                    that Reconciliation Payment Date.

          17.9.4    To the extent that for any reason the amounts to be paid on
                    any Reconciliation Payment Date cannot be calculated in
                    accordance with sub-section 17.6A, any difference between
                    the amounts paid by a Pool Member and the amounts
                    subsequently shown to be payable by that Pool Member
                    (together with any related adjustments) shall be dealt with
                    at the next Reconciliation Payment Date following full
                    reconciliation of the information unless the Executive
                    Committee determines in any particular case that an
                    adjustment shall be made at an earlier date.

17.10     Postponed Payments:

          17.10.1   If for any reason beyond the reasonable control of the Pool
                    Funds Administrator it is not possible, after application of
                    paragraph 17.9.1, for the Pool Funds Administrator to
                    determine by the close of business on the Notification Date
                    the amounts to be incorporated in the Advice Notes, the Pool
                    Funds Administrator shall inform the Settlement System
                    Administrator, each Pool Member, the Ancillary Services
                    Provider and the Grid Operator that the relevant Settlement
                    Payment Date shall be postponed so that it falls on the
                    second Business Day after the day on which the Pool Funds
                    Administrator reconciles the information provided by the
                    Settlement System Administrator pursuant to sub-section 17.6
                    (any such Payment Date being the "Postponed Settlement
                    Payment Date" and a reference to a Settlement Payment Date
                    in this Schedule shall where applicable include a reference
                    to a Postponed Settlement Payment Date).

          17.10.2   On the Postponed Settlement Payment Date, each Pool Member
                    who took electricity on the Settlement Day to which the
                    Postponed Settlement Payment Date applies and the Grid
                    Operator shall pay interest on all such amounts for each day
                    from and including the originally scheduled Settlement
                    Payment Date to (but excluding) the Postponed Settlement
                    Payment Date at such rate as shall be set from time to time
                    by the Executive Committee or, in the absence of such rate,
                    at the Base Rate and all Pool Members who supplied
                    electricity and the Ancillary Services Provider on such
                    Settlement Day shall be entitled to receive, in addition to
                    the amounts that they are entitled to receive in respect of
                    such supplies, interest on such amounts for each day during
                    the same period and at the same rate. Interest shall accrue
                    from day to day and shall be calculated by the Pool Funds
                    Administrator on a 365 day year basis.

          17.10.3   If for any reason beyond the reasonable control of the Pool
                    Funds Administrator it is not possible, after the
                    application of paragraph 17.9.1, for it to determine by the
                    close of business on a Reconciliation Notification Date the
                    amounts to be incorporated in the Advice Notes in respect of
                    reconciliation adjustments, the Pool Funds Administrator
                    shall forthwith inform the Executive Committee. Unless
                    otherwise directed by the Executive Committee, the Pool
                    Funds Administrator shall arrange to deal with such amounts
                    at the next Reconciliation Notification Date following the
                    necessary information becoming available. Where the
                    necessary information is not available by the final
                    Reconciliation Notification Date, the amounts shall be dealt
                    with as determined by the Executive Committee.

17.11     Further notification: Where instructed by the Executive Committee, or
          where there is an award by a court of competent jurisdiction or an
          arbitrator, or a decision of the Pool Auditor or where rendered
          appropriate by Section 62 of Schedule 9, the Pool Funds


<PAGE>

          Administrator shall issue further or other notification to the Pool
          Members, the Ancillary Services Provider and the Grid Operator in
          accordance with the provisions of this Section 17; and the Business
          Day which falls five Business Days after the date of such notification
          or earlier if practicable shall be a Payment Date.

17.12     Payment by Pool Debtors:

          17.12.1   Each Pool Debtor shall without defence, set-off or
                    counterclaim (but without prejudice to any other rights or
                    remedies available to such Pool Debtor) make payment on the
                    relevant Payment Date of the full amount (including United
                    Kingdom Value Added Tax) so notified as being payable by it
                    for the account of those Pool Members and, as the case may
                    be, the Ancillary Services Provider so notified as being
                    entitled to receive payments. Payment shall be made in
                    accordance with the terms of this Schedule.

          17.12.2   For the avoidance of doubt no payment made shall be treated
                    as being paid on account or subject to any condition or
                    reservation, notwithstanding the provisions for the making
                    of subsequent adjusting payments provided in this Schedule.

          17.12.3   The provisions of sub-section 5.14 shall apply to any
                    payment insofar as it is or may constitute an overpayment.

17.13     Liability several: Save as otherwise expressly provided, the liability
          of each Pool Member and the Grid Operator for amounts payable by it
          pursuant to this Schedule is several and no Pool Member shall be
          liable for the default of any other Pool Member or the Grid Operator
          and the Grid Operator shall not be liable for the default of any Pool
          Member.

          Ancillary Services Provider who is required to pay interest and to
          each Pool Member, the Ancillary Services Provider and the Grid

19.       PAYMENT PROCEDURE

19.1      Instructions for payment:

          19.1.2    Each Pool Member, the Ancillary Services Provider and the
                    Grid Operator shall, in respect of each Payment Date on
                    which it is under an obligation to make a payment under this
                    Schedule, make such arrangements as will ensure that such
                    payment is credited to the relevant Collection Account in
                    sufficient time to allow such Settlement Bank to make
                    irrevocable arrangements to remit to the Pool Clearing
                    Account by 12.30 hours the amount payable by that Pool
                    Member, the Ancillary Services Provider or (as the case may
                    be) the Grid Operator in respect of that Payment Date.

          19.1.2    Each Pool Member, the Ancillary Services Provider and the
                    Grid Operator shall ensure all remittances by its bank to
                    the relevant Collection Account shall be remittances for
                    value on the relevant Payment Date.

<PAGE>

19.2      Pool Funds Administrator's responsibilities:

          19.2.1    As soon as practicable and in any event not later than 13.00
                    hours on each Payment Date the Pool Funds Administrator
                    shall take such action as is required to ensure that all
                    amounts required to be credited to each Collection Account
                    on such Payment Date have been so credited (or if not so
                    credited, the reason therefor established).

          19.2.2    As soon as practicable and in any event not later than 13.30
                    hours on each Payment Date the Pool Funds Administrator
                    shall take such action as is required to ensure that all
                    amounts credited to each Collection Account on such Payment
                    Date in accordance with sub-section 19.1 have been remitted
                    to the Pool Clearing Account.

          19.2.3    As soon as practicable and in any event not later than 14.30
                    hours on each Payment Date the Pool Funds Administrator
                    shall take such action as is required to ensure that it
                    reconciles the actual amounts credited to each Collection
                    Account and remitted to the Pool Clearing Account on or
                    before 13.30 hours on that Payment Date and the aggregate of
                    such amounts.

19.3      Non-payment: If a Pool Member or the Grid Operator becomes aware that
          a payment for which it is responsible will not be credited to the
          relevant Collection Account by 12.30 hours on the relevant Payment
          Date, it will immediately notify the Pool Funds Administrator, giving
          all details available to the Pool Member or (as the case may be) the
          Grid Operator. The Pool Funds Administrator shall, as soon as it
          becomes aware that a payment will not be remitted, use its best
          endeavours to establish the cause of non-payment.

19.4      Excess payments:

          19.4.1    If by 12.30 hours on any Payment Date the Pool Funds
                    Administrator is advised by a Settlement Bank that the
                    Settlement Bank will be making a payment in excess of the
                    amount notified to the Pool Member or the Grid Operator
                    pursuant to sub-section 18.1 in respect of that Payment
                    Date, or if the Pool Banker notifies the Pool Funds
                    Administrator by 13.30 hours that amounts greater than the
                    amounts notified to the Pool Banker pursuant to paragraph
                    18.1.3 have been credited to the Pool Clearing Account, the
                    Pool Funds Administrator shall use its best endeavours to
                    ascertain the nature of the excess payment, to calculate the
                    entitlement to such payment and to instruct the Pool Banker
                    by 14.30 hours that day to credit the appropriate Settlement
                    Account(s) with the amount determined by the Pool Funds
                    Administrator as falling due to each Pool Creditor in
                    accordance with this Schedule provided that, where an
                    External Pool Member makes a payment in excess of the amount
                    owing by it on any Payment Date and the reason for such
                    overpayment is the difficulty in


<PAGE>

                    remitting funds on a future Payment Date because of the
                    mismatch of bank and public holidays between countries, the
                    Pool Funds Administrator shall instruct the Pool Banker to
                    credit the Pool Reserve Account with the amount of the
                    excess.

          19.4.2    Any Pool Member or the Grid Operator who instructs its bank
                    to make a payment in excess of the amount owing by that Pool
                    Member or (as the case may be) the Grid Operator on any
                    Payment Date shall simultaneously with giving such
                    instructions advise the Pool Funds Administrator in writing
                    of the amount of the excess payment providing a description
                    of what the Pool Member or the Grid Operator considers the
                    excess payment relates to.

19.5      Payment to Pool Creditors:

          19.5.1    The Pool Funds Administrator shall, prior to 14.30 hours on
                    each day, calculate the amounts available for distribution
                    to Pool Creditors on that day.

          19.5.2    As soon as practicable and not later than 14.30 hours on
                    that day the Pool Funds Administrator shall arrange for the
                    remittance from the Pool Clearing Account to the relevant
                    Settlement Accounts maintained by the Pool Creditors of the
                    aggregate of amounts determined by the Pool Funds
                    Administrator to be available for payment to Pool Creditors
                    and, if required, arrange for the transfer of amounts from
                    the Pool Reserve Account or the Pool Borrowing Account to
                    the Pool Clearing Account or vice versa. 19.6 Making good
                    the Pool Reserve Account: If the Pool Reserve Account is
                    debited or credited in or towards clearing the Pool Clearing
                    Account, the Pool Funds Administrator shall as soon as
                    possible thereafter take the necessary steps, including
                    making any calculations or taking any action in accordance
                    with Section 21, to reverse the debit or credit to the Pool
                    Reserve Account and/or to make a call under a Letter of
                    Credit.

19.7      Prohibition on transfers: The Pool Funds Administrator shall not at
          any time instruct the Pool Banker to transfer any sum from a Pool
          Account to another account (not being a Pool Account) unless that
          account is a Settlement Account.

19.8      Application of payments: Where payments in respect of more than one
          Settlement Day are required to be settled on a Payment Date, payments
          shall be, and shall be deemed to be, settled in the following order of
          priority:-

          19.8.1    first, in or towards settlement of amounts outstanding under
                    this Schedule in respect of Timetabled Reconciliation Runs
                    (with the longest outstanding Settlement Day to which a
                    Timetabled Reconciliation Run relates being settled first);
                    and
<PAGE>

          19.8.2    secondly, in or towards settlement of amounts outstanding
                    under this Schedule in respect of Stage 1 Settlement Runs
                    and Stage 2 Initial Settlement Runs (with the longest
                    outstanding Settlement Day to which a Settlement Run relates
                    being settled first).

19.9      Bank contacts:

          19.9.1    Upon written request of the Pool Funds Administrator each
                    Pool Member, the Ancillary Services Provider and the Grid
                    Operator shall provide the Pool Funds Administrator in
                    writing with the name of, and communication details for, one
                    or more individuals at the branch of its Settlement Bank
                    from which payments or payment instructions required to be
                    made or given by it pursuant to this Schedule originate (the
                    "Local Branch") who is (are) familiar with the payment
                    procedures set out in this Section 19 applicable to such
                    Pool Member, the Ancillary Services Provider or (as the case
                    may be) the Grid Operator, and shall promptly advise the
                    Pool Funds Administrator in writing of any change of any
                    such individual or his communication details.

          19.9.2    Each Pool Member, the Ancillary Services Provider and the
                    Grid Operator hereby authorises the Pool Funds Administrator
                    to contact any such individual to enquire in respect of any
                    Payment Date whether and in respect of what amount
                    instructions have been given for the remittance of any
                    payment required to be made by such Pool Member, the
                    Ancillary Services Provider or (as the case may be) the Grid
                    Operator under this Schedule and/or whether such payment has
                    been remitted or otherwise made as provided for in this
                    Schedule, and undertakes not to withdraw, qualify or revoke
                    such authority at any time.

          19.9.3    Each Pool Member, the Ancillary Services Provider and the
                    Grid Operator shall instruct its Local Branch to co-operate
                    with the Pool Funds Administrator accordingly and to provide
                    the Pool Funds Administrator with all such information as is
                    necessary to answer such enquiries. The Pool Funds
                    Administrator shall comply with all reasonable security
                    arrangements imposed by the relevant Pool Member, the
                    Ancillary Services Provider or the Grid Operator or any
                    Local Branch.

20.       ALTERNATIVE PAYMENT PROCEDURE

20.1      Alternative Payment procedure: Without prejudice to other obligations
          in this Agreement not substituted by the provisions of this Section
          20, the provisions set out in this Section 20 shall apply if, for any
          reason, it is not possible to apply the procedures contemplated by the
          Notified Payments System and for so long as it is not possible to
          apply such procedures.


<PAGE>

20.2      Pool Debtor to effect remittance: Each Pool Debtor shall, in respect
          of each Payment Date on which it is under an obligation to make a
          payment under this Agreement, give instructions to its bank, which it
          undertakes not to qualify, withdraw or revoke, to effect remittance to
          the Pool Clearing Account of the amount payable by that Pool Debtor to
          be received on that Payment Date.

20.3      Receipt of remittance: Any remittance must be received by the Pool
          Banker in the Pool Clearing Account no later than 12.30 hours on the
          Payment Date unless arrangements have been made between the Pool
          Banker and the relevant Pool Member or the Grid Operator (as the case
          may be) which shall be notified to the Pool Funds Administrator and
          which are satisfactory to the Pool Banker such that funds will be
          received for value on that Payment Date. The Pool Members and the Grid
          Operator shall ensure that instructions are given to their banks in
          sufficient time to ensure that their respective banks comply with this
          time limit.

20.4      Method of remittance: The Parties acknowledge and agree that when
          practicable to give effect to sub-section 20.3 a Pool Debtor shall
          cause remittances to be effected through CHAPS but, where not
          practicable or where the amount payable is less than the minimum
          individual amount then processed through CHAPS, the Pool Member and
          the Grid Operator shall ensure by whatever means at their disposal
          that remittance for value on the relevant Payment Date is made for
          credit to the Pool Clearing Account not later than 12.30 hours.

20.5      Notification of non-payment: The Parties acknowledge and agree that if
          a Pool Debtor becomes aware that a payment for which it is responsible
          will not be remitted to the Pool Banker by 12.30 hours on the relevant
          day, and where satisfactory arrangements, as referred to in
          sub-section 20.3, have not been made, it shall immediately notify the
          Pool Funds Administrator, giving all details available to that Pool
          Debtor.

20.6      Payment default: If the Pool Funds Administrator determines at any
          time after 12.30 hours on any day that a remittance which should have
          been credited on that day to the Pool Clearing Account has not been
          made (or that the credit has not been received) (in whole or in part)
          and where satisfactory arrangements, as referred to in sub-section
          20.3, have not been made, the provisions of Section 21 shall apply
          mutatis mutandis.

20.7      Late payment: If, after the Pool Funds Administrator has either
          debited the Pool Reserve Account or made a call under a Letter of
          Credit, the Pool Banker receives the remittance which had not been
          credited to the Pool Clearing Account by 12.30 hours, then such
          remittance shall be credited to the Pool Reserve Account.

20.8      Payments to Pool Creditors: The Pool Funds Administrator shall, prior
          to 14.30 hours on each day, calculate the amounts available for
          distribution to Pool Creditors on that day (including amounts
          resulting from the application of sub-section 20.6). Not later than
          14.30 hours on that day the Pool Funds Administrator shall give
          instructions to the Pool


<PAGE>

          Banker, which it undertakes not to qualify, withdraw or revoke, to
          make same day value remittances to the Pool Creditors.

20.9      Construction: Where the provisions of this Section 20 apply references
          in Sections 5 and 18 and sub-section 21.1 to "Settlement Bank" and
          "Collection Account" shall be construed as references to "bank" and
          "Pool Clearing Account" respectively.

21.       PAYMENT DEFAULT

21.1      Payment default: Subject to sub-section 21.12, if, by 12.30 hours on a
          Payment Date, the Pool Funds Administrator has been notified by a
          Settlement Bank or it otherwise has reason to believe that a
          Settlement Bank will not remit to the Pool Clearing Account all or any
          part (the "Amount in Default") of any amount which has been notified
          by the Pool Funds Administrator as being payable by a Pool Debtor (the
          "Non-paying Pool Debtor") on the relevant Payment Date in sufficient
          time to ensure that such amount can be cleared through the Pool
          Clearing Account not later than the close of banking business on such
          Payment Date, the Pool Funds Administrator shall act in accordance
          with the following provisions (or whichever of them shall apply) in
          the order in which they appear until the Pool Funds Administrator is
          satisfied that the Pool Clearing Account will clear not later than the
          close of business on the relevant Payment Date:-

          21.1.1    if the Pool Funds Administrator has been able to identify
                    the Non-paying Pool Debtor in sufficient time to apply this
                    paragraph 21.1.1 and to the extent that the Non-paying Pool
                    Debtor is entitled to receive payment from any Pool Debtor
                    pursuant to this Schedule on the relevant Payment Date, then
                    the Pool Funds Administrator shall (unless it reasonably
                    believes that such set-off shall be unlawful) set off the
                    amount of such entitlement against the Amount in Default;

          21.1.2    if the Pool Funds Administrator has been able to identify
                    the Non-paying Pool Debtor in sufficient time to apply this
                    paragraph 21.1.2, the Pool Funds Administrator shall debit
                    the Pool Reserve Account and credit the Pool Clearing
                    Account with a sum not exceeding the amount of funds
                    standing to the credit of the Non-paying Pool Debtor in the
                    Pool Reserve Account;

          21.1.3    subject to sub-section 21.2, the Pool Funds Administrator
                    shall debit the Pool Reserve Account and credit the Pool
                    Clearing Account with a sum not exceeding the amount of
                    funds then standing to the credit of the Pool Reserve
                    Account to the extent that they represent Security Cover
                    provided in accordance with paragraph 15.1.2, the transfer
                    of such amount as is not attributable to the funds standing
                    to the credit of the Non-paying Pool Debtor being deemed to
                    give rise to a series of loans to the Non-paying Pool Debtor
                    by each Providing Member and the Grid Operator rateably
                    according to its share of the funds standing to the credit
                    of the Pool Reserve Account to the extent


<PAGE>

                    that they represent Security Cover provided in accordance
                    with paragraph 15.1.2, at the time immediately prior to the
                    transfer, such loans to be repayable on demand and to carry
                    interest at the Base Rate (or at such other rate as shall be
                    set from time to time by the Executive Committee) and in any
                    case repayable not later than two Business Days after they
                    arise after which, to the extent that any such loans remain
                    outstanding, such loans shall carry interest at the Default
                    Interest Rate (which interest shall be credited to the Pool
                    Ledger Account of the relevant Providing Member and (where
                    applicable) the Grid Operator). Each Providing Member and
                    the Grid Operator hereby irrevocably authorises the Pool
                    Funds Administrator to advance, collect in and enforce
                    payment of such loans for its account and on its behalf and
                    each Pool Member and the Grid Operator hereby irrevocably
                    consents to the making of such loans to the extent that such
                    Pool Member or (as the case may be) the Grid Operator has a
                    share in the Pool Reserve Account;

          21.1.4    if the Pool Funds Administrator has been able to identify
                    the Non-paying Pool Debtor in sufficient time to apply this
                    paragraph 21.1.4 and provided that the Pool Funds
                    Administrator is satisfied that the proceeds of a call under
                    the Letter of Credit will be paid into the Pool Clearing
                    Account in sufficient time to ensure that it will clear not
                    later than the close of business on the relevant Payment
                    Date, the Pool Funds Administrator shall make a call under
                    the Letter of Credit supplied by the Non-paying Pool Debtor
                    in a sum not exceeding the available amount of such Letter
                    of Credit, and the Pool Funds Administrator shall cause the
                    proceeds of such call to be paid into the Pool Clearing
                    Account;

          21.1.5    subject to sub-section 21.2 and provided that the Pool Funds
                    Administrator is satisfied that the proceeds of a call under
                    a Letter of Credit will be paid into the Pool Clearing
                    Account in sufficient time to ensure that it will clear not
                    later than the close of business on the relevant Payment
                    Date, the Pool Funds Administrator shall make a call under
                    one or more Letters of Credit supplied by Pool Members or
                    the Grid Operator (other than the Non-paying Pool Debtor) in
                    a total sum not exceeding the total available amount of all
                    such Letters of Credit to the extent that such amount
                    represents Security Cover provided in accordance with
                    paragraph 15.1.2, and the Pool Funds Administrator shall
                    cause the proceeds of such call or calls to be paid into the
                    Pool Clearing Account. The transfer of such proceeds into
                    the Pool Clearing Account shall be deemed to give rise to a
                    series of loans to the Non-paying Pool Debtor by each
                    Providing Member or the Grid Operator whose Letter of Credit
                    was called rateably according to the amounts called under
                    their respective Letter of Credit, such loans to be
                    repayable on demand and to carry interest at the Base Rate
                    (or at such other rate as shall be set from time to time by
                    the Executive Committee) and in any case repayable not later
                    than two Business Days after they arise after which, to the
                    extent that any such loans remain outstanding, such loans
                    shall carry interest at the Default Interest Rate (which
                    interest shall


<PAGE>

                    be credited to the Pool Ledger Account of the relevant
                    Providing Member and (where applicable) the Grid Operator).
                    Each Providing Member and the Grid Operator hereby
                    irrevocably authorises the Pool Funds Administrator to
                    advance, collect in and enforce payment of such loans for
                    its account and on its behalf and each Pool Member and the
                    Grid Operator hereby irrevocably consents to the making of
                    such loans to the extent that such Pool Member or (as the
                    case may be) the Grid Operator has a share in the Pool
                    Reserve Account; and

          21.1.6    if and to the extent that, notwithstanding application of
                    the foregoing measures, it is not possible to clear the Pool
                    Clearing Account by any of the foregoing means, the Pool
                    Funds Administrator shall reduce payments to all Pool
                    Creditors in proportion to the amounts payable to them on
                    the relevant Payment Date by an aggregate amount equal to
                    the amount necessary to clear the Pool Clearing Account and
                    shall account for such reduction in the Pool Ledger Accounts
                    as amounts due and owing by the Non-paying Pool Debtor to
                    each Pool Creditor whose payments were reduced.

21.2      Amount in default likely to be remedied: The Pool Funds Administrator
          shall not apply paragraph 21.1.3 or 21.1.5 unless it considers in good
          faith that the Amount in Default is likely to be remedied by the
          Non-paying Pool Debtor no later than the next Business Day and in such
          a case the Pool Funds Administrator shall only apply paragraphs 21.1.2
          and 21.1.4 to the extent of any amounts provided by way of Security
          Cover pursuant to paragraph 15.1.2.

21.3      Loans part of Pool Reserve Assets: Any loans arising pursuant to
          paragraph 21.1.3 or 21.1.5 shall be deemed to constitute part of the
          Pool Reserve Assets and all repayments of such loans, together with
          interest thereon, shall be paid into the Pool Reserve Account for the
          account of each Providing Member or the Grid Operator who is deemed to
          have made such loan.

21.4      Repayment of loans: If any loans to a Non-paying Pool Debtor arising
          pursuant to paragraph 21.1.3 or 21.1.5 shall not have been repaid in
          full (together with interest at the rate or rates specified therein)
          by 12.00 hours on the next Business Day after such loan is deemed to
          have arisen, the Pool Funds Administrator shall make a call under the
          Letter of Credit (if any) which shall have been supplied by the
          Non-paying Pool Debtor and which remains outstanding in an amount not
          exceeding the amount necessary to repay such loans and all accrued
          interest in full and, if the proceeds of any Letter of Credit are
          insufficient to repay all outstanding loans to the relevant Non-paying
          Pool Debtor, such proceeds shall be applied towards repayment of each
          such outstanding loan rateably.

21.5      Reduction of payments to Pool Creditors: If, after the date that any
          loans to a Non-paying Pool Debtor arise pursuant to paragraph 21.1.3
          or 21.1.5, the Pool Funds

<PAGE>

          Administrator shall reasonably be of the opinion that the Non-paying
          Pool Debtor will not repay forthwith all of such loans and all accrued
          interest in full or the loans have not been repaid with all interest
          within two Business Days after they arose (whichever occurs first),
          the Pool Funds Administrator shall reduce payments to all Pool
          Creditors in proportion to the amounts payable to them on the Payment
          Date to which the default relates and any succeeding Payment Dates as
          may be required by an aggregate amount necessary to restore the
          balance in the Pool Reserve Account to the sum for the time being
          required under this Schedule to be deposited by the Pool Members and
          the Grid Operator other than the Non-paying Pool Debtor, to the intent
          that all loans arising under paragraphs 21.1.3 and 21.1.5 and
          remaining undischarged after application of the Non-paying Pool
          Debtor's Letter of Credit are discharged in full together with
          interest thereon at the Base Rate (or at such rate as shall be set
          from time to time by the Executive Committee).

21.6      Obligation to make calls: If and whenever the Pool Funds Administrator
          has not applied the provisions of paragraph 21.1.4, and has reduced
          payments to Pool Creditors in accordance with paragraph 21.1.6, it
          shall, on the relevant Payment Date or so soon thereafter as the
          Non-paying Pool Debtor has been identified (but, in any event, not
          later than the close of business on the Business Day following such
          Payment Date) make a call under the Letter of Credit supplied by the
          Non-paying Pool Debtor in a sum sufficient to cover the reduction made
          under paragraph 21.1.6 (but not exceeding the available amount of all
          such Letters of Credit) and the Pool Funds Administrator shall cause
          the proceeds of such call to be paid forthwith into the Pool Reserve
          Account. On the next Business Day following receipt of such proceeds,
          the Pool Funds Administrator shall pay such amounts as have been
          credited to the Pool Reserve Account to the Pool Creditors whose
          payments were reduced in full or (as the case may be) in proportion to
          their respective entitlements including interest on such amounts at
          the Base Rate (or at such rate as shall be set from time to time by
          the Executive Committee). 21.7 Indemnification by Non-paying Pool
          Debtor:

21.7.1    The Non-paying Pool Debtor shall indemnify and keep indemnified each
          Pool Member and the Grid Operator whose Letter of Credit is called
          under paragraph 21.1.5 and/or who is deemed to have made loans under
          paragraph 21.1.3 or 21.1.5 on demand against all costs, expenses and
          losses (including the costs of management time) suffered or incurred
          by such Pool Member or (as the case may be) the Grid Operator arising
          from its Letter of Credit being so called (including the costs of
          reinstating the same) or such loans being deemed to have been made to
          the extent that such Pool Member or (as the case may be) the Grid
          Operator is not compensated under this Section 21. This indemnity
          shall be in addition to and without prejudice to the liability of the
          Non-paying Pool Debtor to repay the loan, together with accrued
          interest, which arises pursuant to paragraph 21.1.5.

<PAGE>

          21.7.2    The Pool Creditors, in proportion to the amounts payable to

                    shall forthwith require (by written notice) that the
                    recipient of the overpayment pay the overpayment as directed
                    by the Pool Funds Administrator and any Pool Creditor who

                    full amount disclosed as owing to it pursuant to the Pool
                    Ledger Account (an "underpayment") that Pool Creditor shall
                    forthwith notify the Pool Funds Administrator of the amount
                    of the underpayment, and the Pool Funds Administrator after
                    consultation with the Pool Banker shall use all reasonable
                    endeavours to identify such person as shall have received
                    any corresponding overpayment and promptly to correct the
                    underpayment.

                    Services Provider or the Grid Operator, such Pool Members,
                    the Ancillary Services Provider or the Grid Operator shall
                    be entitled to interest on such amounts at the Default
                    Interest Rate and for such period as the Pool Funds
                    Administrator improperly holds or has such amounts under its
                    control.

          bring any such proceedings.

25.       CREDIT FACILITY: PAYMENT DEFAULTS

25.1      Purpose of Credit Facility: It is acknowledged that the Credit
          Facility provides an alternative to the Security Cover referred to in
          paragraph 15.1.2 and the Pool Funds


<PAGE>

          Administrator will use the Credit Facility to cover banking error and
          payment error and to minimise reductions of payments to Pool Creditors
          unless it considers in good faith that an Amount in Default is not
          likely to be remedied by the Non-paying Pool Debtor no later than the
          next Business Day.

25.2      Modification of other provisions of this Schedule: If and so long as
          the Credit Facility is unconditionally available to the Pool Funds
          Administrator (whether or not there remains any amount undrawn),

          remaining provisions of this Schedule shall be implemented on the
          basis that the following sub-sections apply.

25.3      Payment default: The Pool Funds Administrator shall operate the Credit
          Facility on the following basis:-

          25.3.1    the Credit Facility may be drawn down by the Pool Funds
                    Administrator if, by 12.30 hours on any Payment Date, there
                    is an Amount in Default unless the Pool Funds Administrator
                    considers in good faith that the Amount in Default is not
                    likely to be remedied by the Non-paying Pool Debtor no later
                    than the next Business Day;

          25.3.2    if paragraph 25.3.1 applies such that the Credit Facility
                    may be drawn down, the Pool Funds Administrator will first
                    act in accordance with paragraph 21.1.1, will then draw on
                    the Credit Facility for an amount not exceeding the
                    available amount under the Credit Facility (after allowing
                    for any repayment to be made to the Facility Bank under
                    sub-section 25.6) and, if it is not possible to clear the
                    Pool Clearing Account by either or both of those means, it
                    will then act in accordance with paragraph 21.1.6; and

          25.3.3    if paragraph 25.3.1 does not apply, then the Pool Funds
                    Administrator will act in accordance first with paragraph
                    21.1.1, then with paragraph 21.1.2, then with paragraph
                    21.1.4 and only then with paragraph 21.1.6.

25.4      Amounts in default: Each Non-paying Pool Debtor will be responsible in
          relation to any Amount in Default in accordance with the following
          paragraphs:-

          25.4.1    each Non-paying Pool Debtor will be responsible for the
                    repayment of all amounts of principal drawn down under the
                    Credit Facility in respect of any Amount in Default relating
                    to that Pool Debtor as if the Pool Funds Administrator had
                    made a loan to such Pool Debtor of the relevant amount and
                    the amounts so payable are to be paid to, or otherwise made
                    available for credit to, the Pool Clearing Account as soon
                    as possible, but in any event no later than two Business
                    Days after the relevant Payment Date;


<PAGE>

          25.4.2    each Non-paying Pool Debtor will be responsible also for
                    interest (determined in accordance with paragraph 25.4.4) on
                    all amounts of principal drawn down under the Credit
                    Facility in respect of any Amount in Default relating to
                    that Pool Debtor as if the Pool Funds Administrator had made
                    a loan to such Pool Debtor of the relevant amount and the
                    amount so payable by way of interest is to be paid to, or
                    otherwise made available for credit to, the Pool Clearing
                    Account by no later than the day notified by the Pool Funds
                    Administrator to such Pool Debtor for payment thereof (being
                    the date which is 2 Business Days prior to the date on which
                    interest is payable under the Credit Facility by the Pool
                    Funds Administrator to the Facility Bank for the month in
                    which the principal amount in question was outstanding);

          25.4.3    each Non-paying Pool Debtor will further be responsible for
                    its proportionate share (determined in accordance with
                    paragraph 25.4.5) of any additional sum payable to the
                    Facility Bank pursuant to the terms of the Credit Facility
                    as if the Pool Funds Administrator had made a loan to such
                    Pool Debtor of the relevant amount and the amount so payable
                    is to be paid to, or otherwise made available for credit to,
                    the Pool Clearing Account forthwith on notification thereof
                    by the Pool Funds Administrator to the Pool Debtor in
                    question;

          25.4.4    for the purposes of paragraph 25.4.2, interest is to be
                    calculated using the effective daily rate of interest
                    reasonably determined by the Pool Funds Administrator on the
                    basis of the aggregate interest (including any compound
                    interest) payable under the Credit Facility in relation to
                    any particular day; and

          25.4.5    for the purposes of paragraph 25.4.3, the proportionate
                    share for a particular Non-paying Pool Debtor is the amount
                    (if any) which the Pool Funds Administrator reasonably
                    determines (after consultation with the Facility Bank) as
                    being the amount of any additional sum payable in accordance
                    with the terms of the Credit Facility attributable to
                    drawings under the Credit Facility made in respect of that
                    Pool Debtor.

25.5      Application of payments: On the Relevant Date the Pool Funds
          Administrator shall, if the amount in question has not been received
          in full from the Non-paying Pool Debtor:-

          25.5.1    first debit the Pool Reserve Account and credit the Pool
                    Clearing Account with a sum not exceeding the amount of
                    funds (if any) standing to the credit of the Non-paying Pool
                    Debtor in the Pool Reserve Account;

          25.5.2    if that sum is insufficient to repay in full the amount in
                    question, the Pool Funds Administrator shall call the Letter
                    of Credit (if any) provided by the Non-paying Pool Debtor
                    (for an amount not exceeding the available amount) and pay
                    or cause the proceeds thereof to be paid into the Pool
                    Clearing Account; and


<PAGE>

          25.5.3    if the amount credited to the Pool Clearing Account after
                    following the foregoing procedure is insufficient, reduce
                    payments to all Pool Creditors in proportion to the amounts
                    payable to them on the Payment Date to which the default
                    relates,

          so that, in any case, the Pool Funds Administrator has available to it
          on the Pool Clearing Account sufficient funds to comply with
          sub-section 25.6. For the purposes of this paragraph, the "Relevant
          Date" is whichever of the following is applicable:-

          (a)       in relation to any principal amount for which a Non-paying
                    Pool Debtor is responsible under paragraph 25.4.1, the last
                    date specified for payment under paragraph 25.4.1;

          (b)       in relation to any principal amount as referred to in
                    sub-paragraph (a), the first date (if earlier than the date
                    referred to in sub-paragraph (a)) on which the Pool Funds
                    Administrator is reasonably of the opinion that the
                    Non-paying Pool Debtor will not repay forthwith all of the
                    amounts of principal in question;

          (c)       in relation to payment of interest under paragraph 25.4.2,
                    the last date for payment thereof; and

          (d)       in relation to an additional amount under paragraph 25.4.3
                    the last date for payment of this amount.

25.6      Payments to Facility Bank: To the extent of any payment by the
          Non-paying Pool Debtor and/or if any of the circumstances described in
          sub-section 25.5 occur, the Pool Funds Administrator will forthwith
          repay to the Facility Bank by credit to the Pool Borrowing Account, if
          applicable, an amount equal, in the former case, to the amount so paid
          and, in the latter case, to the amount which should have been paid by
          the Non-paying Pool Debtor.

25.7      Reduction in payments to Pool Creditors: A reduction in payments as
          contemplated by paragraph 25.5.3 will also apply in the event of any
          amounts drawn down under the Credit Facility being required to be
          repaid in accordance with the terms of the Credit Facility and the
          Pool Funds Administrator shall account for such reduction in the Pool
          Ledger Accounts as amounts due and owing by the Non-paying Pool Debtor
          to each Pool Creditor whose payments were reduced.

25.8      Enforcement of claims and other provisions: Sub-sections 21.7, 21.8,
          21.9, 21.10 and Section 24 shall have effect in relation to amounts
          due from a Non-paying Pool Debtor which arise under the foregoing
          sub-sections.

25.9      Unavailability of Credit Facility: If at any time the Credit Facility
          ceases to be unconditionally available and paragraph 15.1.2 shall
          thereupon have become effective,


<PAGE>

          the whole or any part of the Security Cover thereby required to be
          provided by each Providing Member or the Grid Operator may be provided
          by a credit to the Pool Reserve Account, unless otherwise determined
          by the Executive Committee. The Executive Committee shall from time to
          time assess (in consultation with the Pool Funds Administrator) and
          determine the amount of Security Cover which would be required
          pursuant to paragraph 15.1.2 as if that paragraph were in effect and
          such assessment and determination shall apply for the purposes of
          paragraph 16.2.2 if paragraph 15.1.2 becomes applicable, pending any
          revised assessment by the Executive Committee.

25.10     Interpretation: Terms and expressions used in this Section 25 shall,
          unless the context otherwise requires, have the same meanings as are
          given to them for the purposes of Section 21.

26.       CREDIT FACILITY: GENERAL

26.1      Notifications to the Executive Committee: The Pool Funds Administrator
          shall notify the Executive Committee forthwith:-

          26.1.1    on it becoming aware of any circumstances which might lead
                    to an event under the Credit Facility as a result of which
                    the Credit Facility might cease to be available; and

          26.1.2    upon receipt of a written demand from the Facility Bank
                    pursuant to the terms of the Credit Facility as a result of
                    which the Facility ceases to be available; and

          26.1.3    in the event that the Facility Bank requires any additional
                    amount to be paid under the Credit Facility by reason of any
                    increased costs to the Facility Bank or any changes in
                    circumstances.

26.2      Notifications to Providing Members and the Grid Operator: The Pool
          Funds Administrator shall notify the Providing Members and the Grid
          Operator as soon as reasonably practicable after receipt by it of a
          notice from the Facility Bank that an additional amount will or may be
          payable by the Pool Funds Administrator to the Facility Bank under the
          terms of the Credit Facility.

26.3      Amendment and Cancellation:

          26.3.1    The Pool Funds Administrator shall not:-

                    (a)       amend or supplement, or agree to any amendment or
                              supplement to, the terms of the Credit Facility
                              without the approval of the Executive Committee;
                              or


<PAGE>

                    (b)       cancel the Credit Facility unless either the
                              approval of the Executive Committee has been
                              obtained or paragraph 26.3.2 applies.

          26.3.2    The Pool Funds Administrator shall cancel the Credit
                    Facility in full at any time if a resolution to that effect
                    is passed (on a simple majority vote) by the Providing
                    Members in separate general meeting and the Grid Operator
                    consents or if all Providing Members and the Grid Operator
                    have requested such cancellation.

26.4      Extension and Renewal: The Pool Funds Administrator shall negotiate
          with the Facility Bank an extension or renewal of the Credit Facility
          on the instructions of the Executive Committee and, in the absence of
          such instructions, shall begin negotiations with the Facility Bank no
          later than ten weeks before the Credit Facility is due to terminate in
          accordance with its terms, with a view to the extension or renewal of
          the Credit Facility on substantially the same terms for a further year
          and, in any event, to keep the Executive Committee informed on a
          timely basis of the progress of any such negotiations. The Pool Funds
          Administrator shall, however, act only with the approval and consent
          of the Executive Committee in agreeing any extension or renewal of the
          Credit Facility and the Executive Committee shall be responsible for
          deciding whether or not to renew or extend the Credit Facility and, if
          so, on what terms and for what period.

26.5      Fees not attributable to a particular Providing Member or the Grid
          Operator: Any fees (and any additional amounts payable under the terms
          of the Credit Facility which are not the responsibility of any
          particular Providing Member or the Grid Operator) charged under the
          Credit Facility to the Pool Funds Administrator shall be recharged to
          the Providing Members, in accordance with their respective Providing
          Member Contributory Shares (to be calculated on the basis of those
          current on the date on which the relevant fee (or the relevant portion
          thereof) or additional amount is payable by the Pool Funds
          Administrator under the Credit Facility and having deducted the
          relevant Credit Facility Contribution).

26.6      Fees attributable to the Grid Operator: The Grid Operator shall, from
          the date on which it first becomes a Pool Debtor and for the period
          thereafter during which the Credit Facility is in place, pay each year
          to the Pool Funds Administrator the Credit Facility Contribution on a
          date agreed from time to time by the Grid Operator and the Pool Funds
          Administrator (and, failing such agreement, on 31st January in each
          year). If the Credit Facility is available for part of a year only,
          the Credit Facility Contribution shall be adjusted accordingly on a
          pro rata basis.

26.7      No additional charge: The Pool Funds Administrator shall not make any
          additional charge for arranging, participating in or administering the
          Credit Facility.

                               Contributory Shares



1.        CONTRIBUTORY SHARE

The Contributory Share of a Pool Member shall be calculated in accordance with
the following provisions of this Schedule.

2.        POINTS

Subject as provided in Section 3, in respect of each month:-

2.1       each Pool Member which is a Generator shall receive in that capacity
          one point (a "Point") for each MWh of Genset Metered Generation of all
          Allocated Generating Units for all Settlement Periods falling in the
          Calculation Period relative to such month; and

2.2       each Pool Member which is a Supplier shall receive in that capacity
          such number of points (each a "Point") as is equal to the total MWh of
          Aggregate Demand taken by that Pool Member in all Settlement Periods
          falling in the Calculation Period relative to such month.

For the purposes of this Section 2:-

(A)       a Generating Unit shall be an Allocated Generating Unit of a Pool
          Member (in this Section, the "Identified Pool Member") if it belongs
          to the Identified Pool Member as of the date on which the Executive
          Committee calculates the Contributory Shares of Pool Members for the
          relevant month pursuant to Section 6. If at any time during such month
          an Allocated Generating Unit shall belong to another Pool Member (in
          this Section, the "Transferee Pool Member"), the Contributory Shares
          attributed to the Identified Pool Member for such month by reason of
          the Allocated Generating Unit belonging to it shall be transferred to
          the Transferee Pool Member as of the date on which such Allocated
          Generating Unit first belongs to the Transferee Pool Member (and the
          Identified Pool Member and the Transferee Pool Member shall jointly
          notify the Executive Committee in writing of such date in good time
          before its occurrence);

(B)       a Generating Unit shall belong to a Pool Member if it is owned by that
          Pool Member and not leased to another person or if it is leased by
          that Pool Member from another person;

(C)       a Pool Member shall notify the Executive Committee promptly on request
          of its Allocated Generating Units and the Executive Committee and each
          other Party may rely on the information in that notification and in
          any notification under paragraph (A) above without further enquiry or
          need to verify that information;

(D)       in determining the meaning of "good time" for the purposes of
          paragraph (A) above one factor to be taken into account is that the
          Settlement System Administrator must be

          allowed sufficient time to effect the necessary changes in Settlement
          associated with the transfer of the relevant Allocated Generating
          Unit;

(E)       the Executive Committee may, upon application of any Pool Member
          involved in any transfer of assets between Pool Members during any
          month, adjust as between the Pool Members involved in such transfer,

                    adjusted Contributory Shares in respect of that month
                    attributable to each Pool Member, based (subject as provided

                    Settlement Runs and Stage 2 Initial Settlement Runs in
                    respect of Settlement Periods falling in the Calculation
                    Period relating to that month; and

          6.1.3     on the Final Calculation Date, calculate for each month in
                    the relevant Accounting Period the adjusted Contributory
                    Shares attributable in respect of that month to each Pool
                    Member, based (subject as provided in sub-section 6.2) on

6.2       If a Pool Member shall cease for whatever reason to participate as a
          Pool Member in any particular capacity, then the Contributory Share of
          that Pool Member in that capacity shall be reduced to zero with effect
          from the date of such cessation. Such reduction shall not apply in
          relation to any calculation to be performed on or after such cessation
          in respect of any date or period before such cessation.

6.3       The Executive Committee shall notify each Pool Member and the Director
          in writing of the Contributory Share or (as the case may be) adjusted
          Contributory Share of each of the Pool Members. The determination of

          Member (whether initially or following any adjustment made pursuant to
          this Schedule) shall (in the absence of manifest error) be final and
          binding for all purposes of this Agreement.

7.        RECORDS

The provisions of Clause 11.9 shall apply mutatis mutandis in respect of each
Pool Member's Points and Contributory Share as if the reference to the period of
eight years were a reference to the period of eight years from the end of the
Accounting Period to which the Points and Contributory Share relate.

          period may be extended or further extended in accordance with the
          terms of this Schedule).

2.2       Term: On 1st April, 1992 EPFAL was appointed by each Pool Member and
          the Ancillary Services Provider as the Pool Funds Administrator for a
          period of three years commencing on 1st April, 1992 and ending on 31st
          March, 1995. EPFAL's appointment as the Pool Funds Administrator was
          then extended beyond 31st March, 1995 for a period ending on 31st
          March, 1999 and has been subsequently renewed on and subject to the
          terms and conditions set out in this Schedule for a period starting on
          the PFA Implementation Date and, subject as hereinafter provided in
          this Schedule, ending on 31st March, 2003 (the period from the PFA
          Implementation Date to 31st March, 2003 (both dates inclusive) being
          the "Current Term").

2.3       Extension of term: EPFAL's appointment as the Pool Funds Administrator
          may be extended beyond the expiry of the Current Term or (as the case
          may be) any extended or further extended term either:-

          2.3.1     if it successfully tenders pursuant to sub-section 4.3 for
                    continuation of its appointment and then on and subject to
                    the terms and conditions of the tender; or

          2.3.2     if at any time prior to that expiry EPFAL and the Executive
                    Committee so agree in writing and then on and subject to
                    such terms and conditions as are so agreed.

2.4       Wholly-owned subsidiary: NGC shall procure that, so long as EPFAL acts
          or is obliged to act as the Pool Funds Administrator, EPFAL at all
          times remains a wholly-owned subsidiary of NGC.

2.5       Independent Contractor: In carrying out its duties and
          responsibilities and otherwise in acting as the Pool Funds
          Administrator under the Agreement, EPFAL shall act as an independent

2.6       Restriction on business: For so long as EPFAL is the Pool Funds
          Administrator EPFAL undertakes to each Party and the Executive
          Committee that it shall not render to any other Party any billing
          service or any other service of any nature whatsoever which is likely
          to give rise to a conflict of interest in the performance by EPFAL of
          its duties and responsibilities as the Pool Funds Administrator under
          the Agreement. EPFAL further undertakes that if it carries on any
          business other than that of Pool Funds Administrator it shall maintain
          separate accounts and records in respect of any other business. EPFAL
          acknowledges and agrees that this undertaking has been the subject of
          discussion and negotiation and is fair and reasonable having regard to
          the revision of the terms and conditions of EPFAL's appointment as the
          Pool Funds Administrator with effect from the PFA Implementation Date.

                    effect on and from the time of the removal of EPFAL or
                    expiry of EPFAL's term as the Pool Funds Administrator
                    (unless such removal is without notice in which case so soon
                    thereafter as is reasonably practicable),

          and in any such case on such reasonable terms as may be agreed between
          EPFAL and its successor as Pool Funds Administrator (but only, in the
          case of such successor, after it has itself obtained the written

          has itself obtained the written consent of the Executive Committee to
          such terms) within the period referred to in the final paragraph of
          sub-section 5.1 (and, in default of agreement of terms, the dispute
          shall be referred to arbitration in accordance with Clause 83), to
          co-operate with any such successor and the Executive Committee so that
          the transfer of duties, responsibilities, assets and know-how to such
          successor is carried out causing as little disruption to the operation
          of the Funds Transfer System and as little inconvenience to the
          Parties as is practicable in all the circumstances.

          Funds Transfer Software and any records, manuals, data or other
          information referred to in sub-section 5.1 and EPFAL shall not be
          entitled to withhold any training, assistance and system support but
          shall continue to co-operate with the Executive Committee and the
          successor Pool Funds Administrator including carrying out its
          obligations set out in sub-sections 5.1 and 5.2 and accordingly EPFAL

          all instructions and directions issued by the Executive Committee to
          EPFAL in its capacity as the Pool Funds Administrator unless such

          obligations as the Pool Funds Administrator under the Agreement or the
          Agreed Procedures.

6.4       Changes: EPFAL in its capacity as the Pool Funds Administrator shall

          thereof in relation to the Funds Transfer Business or any similar or

          Administrator.

7.3       Notification: EPFAL undertakes to notify the Executive Committee
          forthwith in writing if:-

          7.3.1     it is unable to ensure that it is the owner of, or licensee
                    on the terms set out in sub-section 7.2 under, any Future
                    Funds Transfer Software; or

          7.3.2     it receives any claim or notice of any alleged infringement
                    of the rights of any other person by its use of any Funds
                    Transfer Software or challenging its title to, or its right
                    to use, any Funds Transfer Software; or

          7.3.3     it is or becomes aware of any infringement by any third
                    party of its rights in any Funds Transfer Software,

          and to consult with the Executive Committee as to any steps to be
          taken in respect of any such situation.

7.4       Infringement: EPFAL hereby further represents and warrants to and
          undertakes with each of the Pool Members and the Executive Committee
          that the use of any Future Funds Transfer Software in connection with
          the Funds Transfer Business will not infringe the rights of any other

          under which it holds Future Funds Transfer Software.

          Software or give to such person a copy of, or permit such person to
          use, Funds Transfer Software or otherwise derive any benefit or profit
          therefrom (other than by itself using such Funds Transfer Software for
          the purpose of the Funds Transfer Business).

          keep indemnified each of the Pool Members and the Executive Committee
          from and against any and all loss, liability, damages, costs and
          expenses which it may suffer or incur arising out of or resulting from
          any breach by the Pool Funds Administrator of any of the terms,
          representations, warranties and undertakings contained in this Section

                    may be) the Reconciliation Fee for that PFA Accounting
                    Period to be recalculated, it would yield a different result

                    Period (or, as the case may be, from that most recently

<PAGE>

                    recalculated for that PFA Accounting Period pursuant to this
                    paragraph 8.6.1) EPFAL shall promptly recalculate the Basic
                    Fee or (as the case may be) the Reconciliation Fee and
                    notify the Executive Committee in writing of the amount
                    thereof. Such notification shall be accompanied by a
                    statement showing in reasonable detail the calculation of
                    such amount. Subject to sub-section 8C.3, such recalculated

                    take effect for the period from the date falling one month
                    after the receipt by the Executive Committee of such
                    notification until the end of the then current PFA
                    Accounting Period (or until further recalculated under this

          8.6.2     if at any time the total number of Active Trading Pool
                    Member Identities shall exceed 225 or the total number of
                    Market Domain Identities shall exceed 85, EPFAL may request
                    the Executive Committee to review the basis of calculation
                    and/or the amount of the Basic Fee or (as the case may be)
                    the Reconciliation Fee in accordance with Section 8C; and

          8.6.3     EPFAL and the Executive Committee shall within one month

                    exceeding one month (or such longer period as EPFAL and the

                    agreeing any appropriate adjustment in the Base Sum of the
                    Reconciliation Fee to reflect the calculation of the
                    Reconciliation Fee as shown in that Statement of PFA Costs
                    and Fees. If EPFAL and the Executive Committee shall agree

                    such adjustment shall take effect in accordance with the
                    terms of that agreement. If no agreement is reached under
                    this paragraph 8.6.3, EPFAL or the Executive Committee may

                    termination of EPFAL's appointment as the Pool Funds
                    Administrator pursuant to sub-section 3.2A, being the amount
                    (if any) by which the 1998 PFA Development Costs exceeds the
                    aggregate of all 1998 PFA Development Fees recovered by

10.4      Tender Costs:

          10.4.1    If, during any PFA Accounting Period, the Pool Funds
                    Administrator reasonably believes that any of the category
                    of services within the definition of PFA Operating Costs are
                    likely to exceed the amount of that expenditure for that
                    category or sub-category or other items of cost provided for
                    in the PFA Budget by more than 5 per cent., the Pool Funds
                    Administrator shall notify the Executive Committee
                    accordingly and explain the reasons for the increase. The
                    Executive Committee may require the Pool Funds Administrator
                    to invite tenders for any of the categories or
                    sub-categories or items of cost which are so exceeded, in
                    accordance with paragraph 10.4.3.

          10.4.2    If the Executive Committee considers that the amount
                    budgeted for any category or sub-category or other item of
                    cost in the PFA Budget is unreasonable then the Executive
                    Committee may require the Pool Funds Administrator to invite
                    tenders for any of the categories or sub-categories or other
                    items of cost in the PFA Budget in accordance with paragraph
                    10.4.3.

          10.4.3    Within seven Business Days after receipt of a notice given
                    pursuant to paragraph 10.4.1 the Executive Committee shall
                    notify the Pool Funds Administrator in writing whether it
                    wishes the Pool Funds Administrator to seek a further tender
                    for the service in question. If the Executive Committee so
                    notifies the Pool Funds Administrator that it requires a
                    further tender to be sought, the Pool Funds Administrator
                    shall obtain a further tender and shall give the Executive
                    Committee reasonable details of that further tender and at
                    the same time shall notify the Executive Committee of which
                    tender it has chosen to accept together (if applicable) with
                    reasons as to why it has not chosen the lowest price tender.

          10.4.4    If the Executive Committee fails to notify the Pool Funds
                    Administrator within the time period referred to in
                    paragraph 10.4.2 or notifies the Pool Funds Administrator
                    that it does not wish it to seek a further tender, the Pool
                    Funds Administrator may accept the original tender.

          amount from and including the date of default to the date of actual
          payment (as well after as before judgment) at the rate which is 4 per
          cent. per annum above the Base Rate from time to time of National
          Westminster Bank PLC during each period of default.

          Budget. EPFAL shall adjust the amount of each such payment by
          reference to the most recent Statement of PFA Costs and Fees and so as
          to take into account the PFA Operating Costs, the PFA Annual Fees and
          the Bank Charges during the previous PFA Accounting Period and
          anticipated costs in respect of the same during the current PFA
          Accounting Period and shall recover from or, as appropriate, credit to
          each Pool Member its due proportion of the difference between the
          actual and anticipated PFA Operating Costs, PFA Annual Fees and Bank
          Charges and payments received in respect of such costs, fees and
          charges in each case for the previous and the current PFA Accounting
          Period. Such recovery or credit shall take place by reference to an
          adjustment to each Pool Member's charges for the current PFA
          Accounting Period.

15.6      New and Former Pool Members: Any Pool Member which is a Pool Member
          for part only of any PFA Accounting Period shall pay charges on an

          be reasonable for such PFA Accounting Period on the basis of the
          allocation of charges set out in Section 17. Adjustments to charges on
          all Pool Members as a result of existing Pool Members leaving or new
          Pool Members joining will be made following, and shall be set out in,
          the Statement of PFA Charges submitted for the relevant PFA Accounting
          Period pursuant to sub-section 10.7 whereupon the Pool Members and/or
          former Pool Members shall be required to pay such additional amount or
          be entitled to such reimbursement as may be determined in accordance
          with the Agreement by an adjustment to charges in the then current PFA
          Accounting Period.

16.       BANK CHARGES

Bank Charges: EPFAL in its capacity as the Pool Funds Administrator shall

                    (a)       first, in order to recover the discrete costs
                              referable to each Pool Member during such PFA

                              Schedule 11 which are directly referable to such

                    (b)       secondly, 100 per cent. of such balance (less the
                              costs recovered pursuant to paragraph 17.3.2(a))
                              shall be allocated amongst all Pool Members during

                              Accounting Period. For this purpose, each Pool
                              Member's due proportion of the charges shall be
                              assessed first by reference to the then latest

                              by the Executive Committee for the period and each
                              part thereof to which such charges relate (or, if

                              period for which no such calculation has yet been
                              made, by reference to the then most recently

                              Members) and shall thereafter be readjusted from
                              time to time for each day within the relevant
                              period following changes to the Contributory
                              Shares of Pool Members for all or any part of such
                              period or (as the case may be) following the
                              calculation or re-calculation of the Contributory
                              Shares for such period.

17.4      Prima facie evidence: EPFAL's determination of the allocation of all
          costs during any PFA Accounting Period shall, in the absence of
          manifest error, be prima facie evidence thereof.

<PAGE>

17.5      Minimum payments: EPFAL shall not issue any invoice, nor shall any
          Pool Member be obliged to make any payment (whether initially or by
          way of adjustment), if the aggregate amount otherwise payable by that
          Pool Member pursuant to this Section is less than the minimum from
          time to time agreed by the Executive Committee with EPFAL provided
          that if in respect of an Accounting Period such aggregate amount is
          less than such minimum amount, EPFAL shall issue an invoice in respect
          thereof (which the Pool Member shall be required to pay) immediately
          after the Final Calculation Date for such Accounting Period. Where the
          minimum applies, a Pool Member shall remain liable for any amounts
          payable by it but shall not be required to make any payment until such
          time as the amount in question is permitted to be, and is, included in
          an invoice. Sub-section 15.3 shall be construed accordingly.

18.       ADJUSTMENT

18.1      Revision of charges: If the Executive Committee requests EPFAL to
          continue to serve as the Pool Funds Administrator pursuant to
          sub-section 3.1 to allow a successor to be appointed, EPFAL and the
          Executive Committee shall negotiate in good faith for a period not
          exceeding six weeks (or such longer period as EPFAL and the Executive
          Committee may agree in writing) with a view to agreeing a revision of
          the following:-

          18.1.1    the Base Sum to be used in the calculation of each of the
                    Basic Fee and the Reconciliation Fee for the duration of the
                    additional period referred to in sub-section 3.1; and

          18.1.2    the amount of the Pool Administration Fee, the Additional
                    Reconciliation Run Fee and the Special Run Fee.

18.2      Amendment: Any amendment agreed between EPFAL and the Executive
          Committee pursuant to sub-section 18.1 shall take effect in accordance
          with the terms of that agreement.

18.3      Arbitration: If no agreement is reached within the said negotiation
          period the Executive Committee or EPFAL may refer the dispute to
          arbitration pursuant to Clause 83. Pending any such agreement being
          reached or any such dispute being resolved by arbitration, EPFAL shall
          continue to serve as the Pool Funds Administrator for the additional
          period referred to in sub-section 3.1.

19.       ADDITIONAL COMPENSATION

19.1      General: A direction or instruction of the Executive Committee to
          EPFAL in its capacity as the Pool Funds Administrator shall not
          materially increase the duties, responsibilities or liabilities of
          EPFAL as the Pool Funds Administrator beyond those detailed in the
          Agreement as at the PFA Implementation Date and as detailed in the
          Agreed Procedures without proper compensation.

19.2      Compensation: If the Executive Committee gives a direction or
          instruction to EPFAL in its capacity as the Pool Funds Administrator
          which materially increases the duties, responsibilities or liabilities
          of EPFAL as the Pool Funds Administrator beyond those

<PAGE>

          detailed in the Agreement as at the PFA Implementation Date and as
          detailed in the Agreed Procedures, then (subject to sub-section
          19.3):-

          19.2.1    EPFAL shall carry out that direction or instruction unless
                    it has reasonable grounds for refusing so to do in which
                    event it shall forthwith notify the Executive Committee in
                    writing of its refusal and its reasons therefor (and, for
                    this purpose, an increase in the duties, responsibilities or
                    liabilities of EPFAL in its capacity as the Pool Funds
                    Administrator shall not of itself constitute reasonable
                    grounds);

          19.2.2    EPFAL and the Executive Committee shall negotiate in good
                    faith for a period not exceeding one month (or such longer
                    period as EPFAL and the Executive Committee may agree in
                    writing) with a view to agreeing an appropriate increase in
                    the following:-

                    (a)       the Base Sum to be used in the calculation of each
                              of the Basic Fee and the Reconciliation Fee; and

                    (b)       the amount of the Pool Administration Fee, the
                              Additional Reconciliation Run Fee and the Special
                              Run Fee;

          19.2.3    any increase agreed between EPFAL and the Executive
                    Committee pursuant to paragraph 19.2.2 shall take effect in
                    accordance with the terms of that agreement; and

          19.2.4    if there shall be any dispute as to whether that direction
                    or instruction does or did materially increase the duties,
                    responsibilities or liabilities of EPFAL as the Pool Funds
                    Administrator or whether EPFAL has reasonable grounds for
                    refusing to carry out that direction or instruction or if no
                    agreement is reached under paragraph 19.2.2, EPFAL or the
                    Executive Committee may refer the dispute to arbitration in
                    accordance with Clause 83.

19.3      Reservation: The performance by EPFAL of any direction or instruction
          of the Executive Committee shall not prevent EPFAL from later claiming
          that such direction or instruction materially increased its duties,
          responsibilities or liabilities as the Pool Funds Administrator
          provided always that EPFAL shall not be entitled so to claim unless it
          gave written notice to the Executive Committee promptly (and in any
          event within seven days) after first becoming aware that such
          direction or instruction materially increased or was likely materially
          to increase such duties, responsibilities or liabilities, such notice
          to contain detailed reasons in support of why there has been or is
          likely to be such an increase.

19.4      Funds Transfer Software Development Costs:

          19.4.1    EPFAL may at any time and from time to time notify the
                    Executive Committee of the amount of any Funds Transfer
                    Software Development Costs with a view to agreeing the same
                    with the Executive Committee.

<PAGE>

          19.4.2    EPFAL shall arrange for collection from Pool Members of
                    their respective proportionate share of the Funds Transfer
                    Software Development Costs in such manner as may be agreed
                    by EPFAL with the Executive Committee from time to time
                    (which may include collection in advance) and Pool Members
                    shall comply with such collection procedures and, in
                    particular, shall make payment within the time period
                    prescribed by such procedures.

          19.4.3    Any agreement between EPFAL and the Executive Committee
                    pursuant to paragraphs 19.4.1 and 19.4.2 shall take effect
                    in accordance with the terms of that agreement.

          19.4.4    If no agreement is reached under paragraph 19.4.1 within 30
                    days after receipt by the Executive Committee of EPFAL's
                    notification thereunder (or within such longer period as
                    EPFAL and the Executive Committee may agree) or if no
                    agreement is reached under paragraph 19.4.2, EPFAL or the
                    Executive Committee may refer the dispute to arbitration in
                    accordance with Clause 83.

20.       POOL ADMINISTRATION COSTS AND STAGE 2 OPERATIONAL COSTS

20.1      Services: Subject to sub-section 20.2, EPFAL shall provide the
          services referred to in, and shall recover the Pool Administration
          Costs and the Stage 2 Operational Costs in accordance with, Sections 6
          and 7 of Schedule 31.

20.2      Delegation by Executive Committee: The obligations and rights of EPFAL
          under sub-section 20.1 shall subsist only in respect of the period for
          which EPFAL is authorised to carry out the relevant function pursuant
          to Section 6 or 7 of Schedule 31, as the case may be.

20.3      Transfer of responsibilities: If EPFAL is authorised to carry out one
          or more of the functions referred to in sub-section 20.2 and that
          authorisation is then withdrawn or otherwise ceases, EPFAL shall
          co-operate with the Executive Committee or, as the case may be, the
          successor nominee in the transfer of such function(s) so that as
          little inconvenience to the Parties is caused as is practicable in all
          the circumstances and shall make over all such records, manuals, data
          and other information as the Executive Committee or the successor
          nominee may reasonably require to enable it to carry out such
          function(s).

                                PART A : GENERAL

1.        Introduction: A site shall be identified as a Trading Site for the
          purposes of this Agreement in accordance with the following provisions
          of this Schedule.

2.        Application: A Party may apply to the Executive Committee for a site
          to be treated as a Trading Site by sending to the Executive Committee
          a written application in the form prescribed by the relevant Agreed
          Procedure (in this Schedule, a "Trading Site Application") stating the
          class of application and containing the other information and
          supported by the documents and other matters referred to in Part C and
          signed by or on behalf of the Generator concerned and the Supplier
          concerned where there exists a Supplier in respect of that site
          (together in this Schedule, the "Trading Site Applicants").

3.        Decision: The Executive Committee shall consider any Trading Site
          Application within 45 days after receipt in accordance with the
          procedures set out in Part B and (subject to Section 5 of Part B)
          shall within that period make a determination as to whether the site
          the subject of such application (in this Schedule, the "Nominated
          Site") shall be treated as a Trading Site and shall promptly notify
          the Trading Site Applicants and the Settlement System Administrator of
          its determination.

                               PART B : PROCEDURES

1.        Classes: Every Trading Site Application shall state whether it is a
          Class 1, Class 2, Class 3 or Class 4 application and the Executive
          Committee shall consider a Trading Site Application by reference to
          the provisions set out in this Part B for the stated class (or, in the
          case of Section 5, as provided therein).

2.        Class 1: If the Trading Site Application shall state that it is a
          Class 1 application then the Executive Committee shall determine from
          the Trading Site Application and supporting documentation and other
          matters (and any further evidence provided in accordance with Section
          6) if the Nominated Site is a Power Station which is or is to be
          electrically configured in the same manner as is prescribed in one of
          the line diagrams contained in the relevant Agreed Procedure and
          fulfils all the conditions specified in such Agreed Procedure
          applicable to a Class 1 application, in which event the Nominated Site
          shall be treated as a Trading Site.

3.        Class 2: If the Trading Site Application shall state that it is a
          Class 2 application then the Executive Committee shall determine from
          the Trading Site Application and supporting documentation and other
          matters (and any further evidence provided in accordance with Section
          6) if the generation and demand at the Nominated Site are electrically
          connected solely by Dedicated Assets, in which event the Nominated
          Site shall be treated as a Trading Site.

<PAGE>

          In this Section, "Dedicated Assets" means assets and equipment which
          are used solely to connect electrically (a) the location at which the
          generation originates with (b) the location at which the demand is
          taken (and no other), and additionally satisfy one of the diagrammatic
          representations of Dedicated Assets contained in the relevant Agreed
          Procedure.

4.        Class 3: If the Trading Site Application shall state that it is a
          Class 3 application then the Executive Committee shall determine from
          the Trading Site Application and supporting documentation and other
          matters (and any further evidence provided in accordance with Section
          6) if the generation and demand at the Nominated Site are electrically
          connected by Contiguous Assets, in which event the Nominated Site
          shall be treated as a Trading Site.

          In this Section:-

          (a)       "Contiguous Assets" means those Specified Assets and
                    Equipment at a location which connect by one continuous
                    electrical connection the location at which the generation
                    originates with the location at which the demand is taken,
                    which Specified Assets and Equipment are all owned by the
                    Trading Site Applicants and/or are Specified Assets and
                    Equipment in respect of which a contribution is or will be
                    made by the Trading Site Applicants to the provision and
                    installation or maintenance and repair costs thereof or
                    where such Specified Assets and Equipment are already
                    provided and installed, the maintenance and repair costs
                    thereof; and

          (b)       "Specified Assets and Equipment" means assets and equipment
                    identified and quoted in the Connection Agreement of either
                    Trading Site Applicant where such assets and equipment
                    include assets and equipment identified and quoted in the
                    Connection Agreements relating to both Trading Site
                    Applicants which form part of the continuous electrical
                    connection for the purposes of (a) above.

5.        Class 4:

5.1       If the Trading Site Application shall state that it is a Class 4
          application or if the Executive Committee shall determine that the
          Nominated Site the subject of a Class 1, Class 2 or Class 3 Trading
          Site Application does not satisfy the conditions specified in Section
          2, 3 or (as the case may be) 4, the Executive Committee shall
          determine from the Trading Site Application and supporting
          documentation and other matters (and any further evidence provided in
          accordance with Section 6) if the Nominated Site shall be treated as a
          Trading Site having regard to the criteria set out in Section 5.2.

5.2       The criteria referred to in Section 5.1 are:-

          (a)       whether special circumstances existed before 30th March,
                    1990 which demonstrate to the reasonable satisfaction of the
                    Executive Committee that the generation and demand were
                    treated as being on a Trading Site;

<PAGE>

          (b)       whether special circumstances existed before 11th December,
                    1991 which demonstrate to the reasonable satisfaction of the
                    Executive Committee that the generation and demand should
                    have been treated as on a Trading Site;

          (c)       whether, although not satisfying the conditions applicable
                    to a Class 1, Class 2 or Class 3 Trading Site Application,
                    if, to the reasonable satisfaction of the Executive
                    Committee, the Trading Site Application demonstrates
                    sufficient similarities with sites which would satisfy those
                    conditions such that it would be unreasonable not to treat
                    the Nominated Site as a Trading Site;

          (d)       whether there are any other facts or evidence in support of
                    the Trading Site Application which in the reasonable opinion
                    of the Executive Committee demonstrate that the Nominated
                    Site ought to be treated as a Trading Site.

6.        Further evidence: The Executive Committee may request a Trading Site
          Applicant to produce such further evidence as the Executive Committee
          may reasonably require in support of its Trading Site Application
          before the Executive Committee makes any determination as to whether
          the Nominated Site is to be treated as a Trading Site, and the
          Executive Committee shall not be bound to make any determination on
          the issue of whether the Nominated Site is a Trading Site pending
          receipt of such further evidence.

7.        Majorities: Any determination of the Executive Committee in favour of
          treating a Nominated Site as a Trading Site shall require a simple
          majority of the votes cast by Committee Members at the relevant
          meeting provided that in the case of a Trading Site Application which
          falls to be considered under Section 5 the necessary majority shall be
          75 per cent. of all the votes cast by Committee Members.

8.        Effect of determination: If the Executive Committee shall determine
          pursuant to Section 2, 3, 4 or (as the case may be) 5 that a Nominated
          Site is a Trading Site all metered values of all meters associated
          with the Nominated Site and identified in the Trading Site Application
          shall be aggregated in accordance with the provisions of sub-section
          3.3 of, and Section 3.1 or 3.3 (as the case may be) of Appendix 6 to,
          Schedule 9.

                    and equipment electrically connecting the generation and

          (b)       confirmation from the Settlement System Administrator,
                    having duly notified the Grid Operator, that it is satisfied
                    that the metering arrangements at the Nominated Site are
                    compatible with the operation of Settlement;

          (c)       in the case of a Class 2 or Class 3 Trading Site

          salient differences between any such forecast expenditure and the
          budgeted expenditure in respect of each such item or category in the
          immediately preceding ASP Budget.

2.3       Form of ASP Budgets: Each ASP Budget shall be substantially in the
          form of that set out in Part 1 of the Annex (or in such other form as
          the Ancillary Services Provider and the Suppliers in separate general
          meeting (or their appointed representative) may from time to time
          agree).

          Statement of Costs

2.4       Statement of Costs: No later than one month following the date in any
          Accounting Period of the publication of the audited accounts for the
          Ancillary Services Business for the previous Accounting Period, the
          Ancillary Services Provider shall prepare and submit to each Supplier
          a Statement of Costs for such previous Accounting Period. The audited
          accounts of the Ancillary Services Provider and the auditors'
          management letter, to the extent it relates to the economy, efficiency
          and effectiveness of the Ancillary Services Provider in carrying out
          its duties, shall accompany each Statement of Costs for each entire
          Accounting Period.

<PAGE>


2.5       Form of Statement of Costs: The Statement of Costs for any Accounting
          Period shall attribute actual expenditure for such period against,
          inter alia, each of the categories and sub-categories set out in the
          corresponding ASP Budget for such Accounting Period.

2.6       Accompanying Report: Each ASP Budget and Statement of Costs for an
          entire Accounting Period submitted to the Suppliers pursuant to
          sub-section 2.1 or 2.4 shall be supported by a written report of the
          Ancillary Services Provider commenting in reasonable detail upon the
          matters comprised in the categories of expenditure included in such
          ASP Budget or Statement of Costs drawing attention to and giving
          reasons for any unusual commitment or item of expenditure proposed to
          be incurred or which has been incurred and, in the case of a Statement
          of Costs, explaining the difference (if material) between:-

          2.6.1     the amount set against each item or category therein; and

          2.6.2     the amount set against each corresponding item or category
                    in the immediately preceding ASP Budget.

2.7       Accounting Practices: Each ASP Budget and Statement of Costs shall be
          prepared on the basis of the accounting principles and practices used
          to draw up the most recent audited accounts of the Ancillary Services
          Provider and consistently applied. If any Statement of Costs for an
          entire Accounting Period is not prepared on such basis, the Ancillary
          Services Provider shall prepare and submit to the Suppliers a
          pro-forma set of audited accounts of the Ancillary Services Provider
          for such entire Accounting Period which is prepared on the basis of
          the accounting principles and practices used to prepare the relevant
          Statement of Costs. Any changes in the accounting principles and
          practices or their method of application used to prepare audited
          accounts of the Ancillary Services Provider shall be noted in the next
          following ASP Budget or Statement of Costs, as the case may be.

2.8       Statement of Charges: A Statement of Charges shall accompany each
          Statement of Costs.

2.9       Bad debts: The total cost of any bad debts of the Ancillary Services
          Provider arising in any Accounting Period may be taken into account by
          the Ancillary Services Provider in its Statement of Costs for such
          Accounting Period or any subsequent Accounting Period and accordingly
          recovered as part of Total Operating Costs for any such Accounting
          Period.

3.        AUDITORS' OPINION

The Statement of Costs to be sent to the Suppliers pursuant to sub-section 2.4
shall be accompanied by a report from the auditors of the Ancillary Services
Provider considering whether in such auditors' opinion:-

3.1       the Statement of Costs is in agreement with the underlying books and
          records of the Ancillary Services Provider; and

<PAGE>


3.2       Total Operating Costs and Depreciation have been properly extracted
          from the audited financial statements.

Such auditors' report shall also contain such other matters as the Suppliers in
separate general meeting (or their appointed representative) may agree with the
auditors of the Ancillary Services Provider.

4.        ACCOUNTING PERIOD

The first Accounting Period shall run from (and including) 31st March, 1990 to
(and including) 31st March, 1991. Thereafter, unless agreed by the Ancillary
Services Provider and the Suppliers in separate general meeting each Accounting
Period shall be for a period of twelve months. In the event that the Ancillary
Services Provider wishes to change its accounting reference date it shall give
due notice thereof to all Suppliers who shall agree to enter (either themselves
or through their appointed representative) into an amending agreement to give
effect to the same at the cost and expense of the Ancillary Services Provider.

5.        ANCILLARY SERVICES PROVIDER'S CHARGES

5.1       Ancillary Services Provider's charges: In respect of each Accounting
          Period, the Ancillary Services Provider shall be entitled to recover
          from the Grid Operator in addition to the cost of Ancillary Services
          the aggregate of:-

          5.1.1     Total Operating Costs for the relevant Accounting Period (as
                    identified by the Statement of Costs for such Accounting
                    Period to be submitted pursuant to sub-section 2.4); and

          5.1.2     the Margin.

5.2       Recovery of Charges: The Ancillary Services Provider's charges in
          respect of any Accounting Period shall be recovered from the Grid
          Operator on a daily basis in accordance with the Pool Rules and by
          reference to the allocation provided therein by:-

          5.2.1     estimating a daily amount necessary to recover the charge by
                    reference to the ASP Budget and, where appropriate, any
                    under- or over-recovery in respect of any previous
                    Accounting Period; and

          5.2.2     adjusting that amount by reference to any subsequent
                    Statement of Costs.

5.3       Revision of Estimates: If the Ancillary Services Provider reasonably
          believes that the amount which will be recovered under sub-section 5.2
          is likely to be 10 per cent. more or less than the amount to which it
          is entitled under sub-section 5.1 it shall, with the consent of the
          Suppliers in separate general meeting or their appointed
          representative (such consent not to be unreasonably withheld or
          delayed), revise as appropriate the estimate made in accordance with
          sub-section 5.2.

5.4       Sharing of Efficiency: The Ancillary Services Provider shall be
          entitled to the benefit of all Efficiencies and, accordingly, to
          charge Grid Operator the amount of all Efficiencies by

<PAGE>

          including them in ASP Budgets and Statements of Cost in the following
          manner. The amount of any Efficiency arising in any Accounting Period
          shall be identified in the Statement of Costs for such Accounting
          Period submitted pursuant to sub-section 2.4 and shall be taken into
          account in the Statement of Costs for the two successive Accounting
          Periods thereafter. Accordingly, the amount of any Efficiency may be
          included in any Statement of Costs for the two Accounting Periods
          following that in which the Efficiency is identified. In the Statement
          of Costs for the third consecutive Accounting Period and all following
          Accounting Periods thereafter the amount of such Efficiency shall be
          eliminated.

6.        CORPORATE OVERHEAD CHARGES AND PURCHASES

6.1       Corporate Overhead Charges: The Ancillary Services Business may take
          into account in any ASP Budget or Statement of Costs (and consequently
          its charges to Suppliers) all corporate overhead charges payable by
          the Ancillary Services Provider to its immediate holding company or
          any other division of the company of which it is a division provided
          such corporate overhead charges are reasonable and in due proportion
          to the corporate overhead charges payable by other affiliates of the
          Ancillary Services Provider or divisions of the company of which the
          Ancillary Services Provider is a division as reported upon by the
          auditors of the Ancillary Services Provider.

6.2       Goods or services: Purchases of goods or services from affiliates of
          the Ancillary Services Provider shall be on arm's length terms.

7.        FUEL SECURITY

Except to the extent recoverable under any other provision of this Schedule, any
additional costs necessarily incurred by the Ancillary Services Provider in
running the Ancillary Services Business during a Security Period shall be
regarded as beyond the control of the Ancillary Services Provider, which may
recover the same in full from Suppliers provided such costs have been verified
as additional costs by the auditors of the Ancillary Services Provider.
Suppliers shall be obliged to pay the actual amount of such costs and expenses.

8.        CAPITAL EXPENDITURE

8.1       Capital Expenditure (1): The following provisions apply to Capital
          Expenditure by the Ancillary Services Provider in respect of the

                    Services Provider which may be recovered by Depreciation
                    charged to Suppliers shall require the prior approval of the
                    Suppliers in separate general meeting (or their appointed
                    representative), such approval to take into account an
                    appropriate sharing of the Efficiencies arising from such
                    Capital Expenditure;

          8.1.2     Capital Expenditure which may be recovered by Depreciation
                    charged to Suppliers specified in any ASP Budget shall be
                    regarded as approved by the Suppliers in separate general
                    meeting or their appointed representative, as the case may
                    be unless the Suppliers in separate general meeting (or
                    their

<PAGE>

                    appointed representative) notify the Ancillary Services
                    Provider to the contrary within one month after receipt of
                    such ASP Budget;

          8.1.3     in any Accounting Period the Ancillary Services Provider may
                    incur Capital Expenditure which may be recovered by
                    Depreciation charged to Suppliers without the need to
                    consult or obtain the approval of the Suppliers or their
                    appointed representative, as the case may be, up to a
                    maximum of the Individual Limit for each item of Capital
                    Expenditure and a maximum of the Overall Limit for all items
                    of Capital Expenditure and, in the event of the Ancillary
                    Services Provider incurring such Capital Expenditure, it
                    shall notify all Suppliers as soon as practicable
                    thereafter; and

          8.1.4     the Ancillary Services Provider shall be entitled to incur
                    Capital Expenditure which may be recovered by Depreciation
                    charged to Suppliers of any amount without the need to
                    obtain the approval of the Suppliers in separate general
                    meeting (or, as the case may be, their appointed
                    representative) in circumstances where:-

                    (a)       the Ancillary Services Provider would be in breach
                              of its duties under the NGC Transmission Licence
                              unless such Capital Expenditure were incurred; and

                    (b)       it has not reached agreement with the Suppliers in
                              separate general meeting (or, as the case may be,
                              their appointed representative) on such Capital
                              Expenditure within a reasonable period of time.

8.2       Capital Expenditure (2): Capital Expenditure not falling within
          sub-section 8.1 may not be charged as Depreciation to Suppliers.

1.2       Interpretation:

          1.2.1     Wherever a reference is made in this Schedule to a Meter
                    Operator Party or to an Operator, such reference shall be to
                    a Meter Operator Party in its capacity as Meter Operator
                    Party in relation to Stage 1 Metering Systems or, where the
                    context so requires, to an Operator in its capacity as
                    Operator in relation to Stage 1 Metering Systems, but shall
                    not refer to the person which is that Meter Operator Party
                    or Operator in, and shall be in all cases without prejudice
                    to, any other capacity in which such person may be party to
                    this Agreement.

          1.2.2     This Schedule 21 relates only to the rights and obligations
                    of a Meter Operator Party regarding the accurate measurement
                    using Stage 1 Metering Systems of electricity traded under
                    this Agreement. It does not deal with any rights or
                    obligations of any Party relating to Stage 2 Metering
                    Systems as to which other provisions of this Agreement
                    apply.

1.3       Agreed Procedures and Codes of Practice:

          1.3.1     Each of the Parties and each of the Meter Operator Parties
                    undertakes to comply with the Agreed Procedures and the
                    Codes of Practice insofar as applicable to it.

          1.3.2     The Settlement System Administrator shall retain copies of
                    all Agreed Procedures and Codes of Practice applicable to
                    Stage 1 Settlement and of any other documentation referred
                    to in such Agreed Procedures or Codes of Practice and shall
                    provide a copy of all or any thereof to any Party or Meter
                    Operator Party on request and may make a reasonable charge
                    for such provision.

          1.3.3     Notwithstanding the absence from time to time of its express
                    consent, each Meter Operator Party hereby expressly
                    acknowledges and agrees to be bound by the provisions
                    contained in this Agreement which govern the method by which
                    all Agreed Procedures and Codes of Practice may be, from
                    time to time, changed or substituted

<PAGE>

                    and which determine the meaning in any given context of the
                    terms the "relevant Agreed Procedure" and the "relevant Code
                    of Practice".

1.4       Agreed Procedures and Codes of Practice: Referral to the Director:

          1.4.1     Without prejudice to paragraph 1.3.3, where any Meter
                    Operator Party considers that any change proposed to be made
                    to any Agreed Procedure or to any Code of Practice
                    applicable to Stage 1 Settlement would have a material
                    adverse effect on its rights and liabilities as a registered
                    Operator, a Potential Operator or Tariff Operator 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 the
                    Executive Committee) who shall determine, taking into
                    account the views expressed by the Executive Committee and
                    any Parties referred to below in this sub-section, whether
                    such proposed change has such a material adverse effect. The
                    Director's determination shall be final and binding for all
                    purposes.

          1.4.2     For the purposes of enabling any Meter Operator Party to
                    appeal to the Director against a proposed change to any
                    Agreed Procedure or Code of Practice in accordance with
                    paragraph 1.4.1, the Executive Committee shall give all
                    Parties, Meter Operator Parties and the Director notice of
                    the proposed changes at least 14 clear days prior to the
                    implementation of such proposed change in accordance with
                    the provisions of this Agreement.

          1.4.3     If an appeal to the Director against a proposed change to
                    any Agreed Procedure or Code of Practice is made within 14
                    days after notification by the Executive Committee pursuant
                    to paragraph 1.4.2, the change shall not come into effect
                    until the determination of the Director has been made and
                    then subject to paragraph 1.4.4. If no appeal is made within
                    the said 14 days, the change shall come into effect on the
                    expiry of that period (or such later date as the Executive
                    Committee may determine).

          1.4.4     The Director shall within 28 days of receipt of a referral
                    (or within such extended period as the Director shall have
                    notified to the Executive Committee within that 28 day
                    period as being necessary to enable him to reach a
                    considered determination) pursuant to paragraph 1.4.1 make
                    the determination referred to therein giving supporting
                    reasons and:-

                    (i)       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 21 of the appellant Meter
                              Operator Party as registered Operator, as
                              Potential Operator or as Tariff Operator then the
                              proposed change shall come into effect in
                              accordance with the provisions of this Agreement;
                              and

                    (ii)      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

<PAGE>

                              21 of the appellant Meter Operator Party as
                              registered Operator, as Potential Operator or as
                              Tariff Operator, the Director may require that the
                              proposed change not come into effect (in which
                              case such proposed change shall not come into
                              effect) or require that modifications be made to
                              the proposed change to obviate or mitigate such
                              material adverse effect. In the latter case the
                              Executive Committee and each Party whose consent
                              is required to the relevant amendment to that
                              Agreed Procedure or, as the case may be, Code of
                              Practice, shall take all reasonable steps to
                              implement any decision of the Director (for which
                              reasons shall be given) requiring changes to be
                              made to such Agreed Procedure or Code of Practice
                              with the purposes of obviating or, where the
                              Director considers appropriate, mitigating such
                              material adverse effect on such Meter Operator
                              Party.

2.        AMENDMENTS AND MODIFICATIONS

2.1       Obligations: The Parties and Meter Operator Parties expressly
          acknowledge and agree that each Meter Operator Party is bound only to
          the extent of the obligations which are expressly set out or referred
          to in this Schedule (including those provisions incorporated herein by
          reference in Section 24) and not by any other provision of this
          Agreement. Each Meter Operator Party agrees to comply with the
          provisions of this Schedule (including those provisions of this
          Agreement incorporated herein by reference in Section 24). The Parties
          and Meter Operator Parties further expressly agree that any Meter
          Operator Party (in its capacity as such) shall be conferred only with
          such rights in respect of this Agreement as are expressed to be
          conferred on it as Operator or Meter Operator Party pursuant to
          provisions which are expressly set out in this Schedule (including
          those provisions incorporated herein by reference in Section 24) or
          are definitions listed in sub-section 1.1.

2.2       Consent:

          2.2.1     The consent or agreement of any Meter Operator Party shall
                    not be required to any modification, abrogation, amendment
                    or suspension of any provision of this Agreement which is
                    not expressly set out in this Schedule (and for this purpose
                    the provisions of this Agreement incorporated herein by
                    reference in Section 24 shall be deemed to be not set out in
                    this Schedule) or which is not a definition listed in
                    sub-section 1.1. Each Meter Operator Party hereby
                    irrevocably waives any rights which it might be considered
                    or held to have to consent or agree to any such
                    modification, abrogation, amendment or suspension.

          2.2.2     Where under paragraph 2.2.1 a Meter Operator Party would
                    otherwise have a right to consent or agree to a
                    modification, abrogation, amendment or suspension of a
                    provision of this Agreement then that consent or agreement
                    shall not be required in circumstances where the consent or
                    agreement of any Party (not being the Settlement System
                    Administrator, the Grid Operator, the Ancillary Services
                    Provider, the Pool

<PAGE>

                    Funds Administrator or, if it is a Party, any Pool Agent) is
                    also not required under this Agreement to such modification,
                    abrogation, amendment or suspension.

          2.2.3     A Meter Operator Party whose consent or approval need not by
                    virtue of this Section 2 be sought or obtained to any
                    modification, abrogation, amendment or suspension of any
                    provision of this Agreement may refer the matter to the
                    Director as if it were a referral under and in accordance
                    with sub-section 1.4 (and such that the provisions of that
                    sub-section shall apply mutatis mutandis to such referral)
                    provided that in reaching any determination as to whether
                    the proposed change shall come into effect the Director
                    shall consider the nature of the changes upon Meter Operator
                    Parties as a class and shall not have locus standi to
                    consider any perceived or actual prejudice as an individual
                    Meter Operator Party.

2.3       Authorisation to amend: Without prejudice to sub-sections 2.1 and 2.2,
          each Meter Operator Party hereby unconditionally and irrevocably
          authorises and instructs the Chief Executive and each person
          authorised for the purpose by the Executive Committee to sign on its
          behalf amending agreements to this Agreement and to execute any
          agreement which modifies, abrogates, amends or suspends any provision
          of this Agreement in circumstances where such Meter Operator Party's
          consent or approval is not required, and undertakes not to withdraw,
          qualify or revoke such authority and instruction at any time.

2.4       Notification: The Executive Committee shall notify each Meter Operator
          Party of all amendments, modifications, abrogations and suspensions
          which are made to this Agreement for which the consent or agreement of
          such Meter Operator Party is not required.

2.5       Further rights: The Executive Committee shall from time to time
          consider any representations which Meter Operator Parties may make to
          the effect that there are provisions set out in this Agreement but not
          in this Schedule 21 and, accordingly, in respect of which Meter
          Operator Parties are not conferred with rights by virtue of this
          Section 2, which are operating in a manner which is having a material
          effect on the rights and liabilities of such Meter Operator Parties as
          set out herein. The Executive Committee shall consider whether, and
          the extent to which (if at all), such provisions should be recommended
          for incorporation into this Schedule 21.

                    PART 3: METER OPERATOR'S RESPONSIBILITIES

7.        OBLIGATION TO ENSURE COMPLIANT METERING EQUIPMENT

7.1       General Obligation and Commercial Boundary:

          7.1.1     There must always be one and, at any point in time, no more
                    than one Operator for each Stage 1 Metering System which is
                    registered with the Settlement System Administrator.

          7.1.2     All Stage 1 Metering Systems at the site of a Stage 1
                    Non-Pooled Generator, which are part of the same Metering
                    Equipment, must have the same Operator.

          7.1.3     Each Operator shall ensure there is installed a Stage 1
                    Metering System complying with the provisions of this
                    Schedule and Part XV of this Agreement which meets the
                    required levels of accuracy at the commercial boundary at
                    each Site for which it is the Operator and which is as close
                    as reasonably practicable to that commercial boundary taking
                    into account relevant financial considerations. The Parties
                    and Meter Operator Parties acknowledge and agree that
                    Metering Equipment at Power Stations either existing or
                    under construction at the Effective Date might not be
                    situated at the commercial boundary. In such cases, loss
                    adjustment factors may be applied after the Effective Date
                    subject to it being demonstrated to the reasonable
                    satisfaction of the Settlement System Administrator that
                    such loss adjustment factors have been correctly derived.

          7.1.4     To the extent that the required levels of accuracy referred
                    to in paragraph 7.1.3 depend upon associated current and
                    voltage transformers which are not in the ownership or
                    control of the relevant Operator, the relevant Equipment
                    Owner agrees to take reasonable steps to assist the Operator
                    in complying with its obligations under paragraph 7.1.3 by
                    the maintenance and repair of such current and voltage
                    transformers in accordance with the provisions of this
                    Schedule provided that this paragraph 7.1.4 shall be without
                    prejudice to any right to charge for the same and provided
                    further that an Equipment Owner shall not be required by
                    this paragraph 7.1.4 to take steps which would cause it to
                    be in breach of its obligations under its Licence, its
                    Nuclear Site Licence (as defined in sub-section 21.9(a)),
                    the Grid Code or any Distribution Code.

                    due to measuring transformers and connections thereto.
                    Beyond the ranges specified in the relevant Code of Practice
                    and power factors other than unity or zero (as the case may
                    be) limits of accuracy will depend on the characteristics of
                    the individual meters and measuring transformers specified
                    for such Metering Equipment. Such levels of accuracy will,
                    in the event of any uncertainty or dispute, be specified by
                    the Executive Committee.

8.2       Inspection and Testing:

          8.2.1     No less frequently than such period as may be specified in
                    the relevant Code of Practice each Operator shall carry out
                    a routine test of the accuracy of all Metering Equipment
                    comprising a Stage 1 Metering System in respect of which it
                    is the Operator. The Operator shall also carry out a test of
                    the accuracy of all such Metering Equipment in respect of
                    which it is the Operator and which replaces defective or
                    inaccurate Metering Equipment as soon as is reasonably
                    practicable after its installation. Such Operator will give
                    the Settlement System Administrator and the Registrant at
                    least 15 days' prior written notice of the date, time, place
                    and nature of every such test and the Settlement System
                    Administrator and Host PES and the Registrant shall have the
                    right to attend such test should it so require. Any such
                    test as envisaged in this paragraph 8.2.1 shall comply with
                    the relevant Code of Practice.

          8.2.2     If either:-

                    (a)       the Settlement System Administrator has reason to
                              believe that the Metering Equipment comprising a
                              Stage 1 Metering System which an Operator is

                        PART 10: COMMUNICATIONS EQUIPMENT

22.       COMMUNICATIONS EQUIPMENT

22.1      Compatibility: Communications Equipment required for the purposes of
          Stage 1 Settlement at or relating to any Site (which whenever used in
          this Section 22 shall include all Qualifying Sites) must be compatible
          with the communications links provided by the Settlement System
          Administrator pursuant to Clause 60.6.3(a) in respect of that Site.
          Prior to the installation of Communications Equipment required for the
          purposes of Stage 1 Settlement at or relating to any Site the Tariff
          Operator shall consult with the Settlement System Administrator to
          ensure that such Communications Equipment will be compatible with such
          communication links. Where a Tariff Operator becomes aware that
          Communications Equipment required for the purposes of Stage 1
          Settlement at or relating to a Site is used for purposes other than in
          connection with Stage 1 Settlement, it shall notify the Settlement
          System Administrator of any such use or purposes to which that
          Communications Equipment is put.

22.2      Settlement System Administrator's responsibility in respect of
          communications links: Subject to the requirement of the Settlement
          System Administrator to collect data in accordance with Clause 60.6.1
          and subject to the provisions of sub-section 22.1, the Settlement
          System Administrator shall use all reasonable endeavours to ensure
          that the communications link provided by it (but which, for the
          avoidance of doubt, does not form part of Communications Equipment) to
          any Site pursuant to Clause 60.6.3(a) is of the type requested by the
          Tariff Operator.

22.3      Tariff payments:

          (a)       The Settlement System Administrator shall pay from time to
                    time to each Tariff Operator in respect of a Site for which
                    it is the Tariff Operator, an amount (if any) determined in

                    to the relevant Tariff Operator set off amounts payable to

                    amounts payable by the Settlement System Administrator to
                    that Tariff Operator, under the relevant Tariff. Any amounts
                    so set off by the Settlement System Administrator under this
                    sub-section 22.3 shall be deemed to have been received by
                    the Settlement System Administrator for the purposes of
                    sub-section 22.3(b).

          (d)       Notwithstanding the terms of any Tariff, a Tariff Operator
                    shall not be entitled to receive payment of or otherwise
                    recover any sums for or relating to goods or services
                    delivered or provided by it under or for the purposes of
                    this Agreement and invoiced or claimed by the Tariff
                    Operator to or from the Settlement System Administrator or
                    Pool Members more than 90 days after the end of the month in
                    which such goods or services were delivered or provided.

22.4      Refunds: Where a Tariff Operator is removed, resigns or otherwise
          ceases to be Tariff Operator at or relating to any Site it shall pay
          to the Settlement System Administrator such amount (if any) as is set
          out in the relevant Tariff by way of reimbursement of amounts paid to
          it pursuant to sub-section 22.3.

22.5      Additional payments: If a Tariff Operator can demonstrate to the
          reasonable satisfaction of the Settlement System Administrator that
          any relevant payment to be made pursuant to this Section 22 and in
          accordance with the relevant Tariff in respect of any particular Site
          as is described in the relevant Tariff does not reflect the cost to
          such Tariff Operator of providing in respect of Communications
          Equipment at or relating to such Site installation and maintenance
          services in an efficient and economic manner then the Settlement
          System Administrator may negotiate an additional payment to such
          Tariff Operator in respect of Communications Equipment at or relating
          to such Site provided that the Tariff Operator shall be entitled to
          receive such additional payment only if and to the extent that the
          economic and efficient provision of installation and maintenance
          services in respect of the Communications Equipment at or relating to
          that Site is in fact effected. If the Tariff Operator and the
          Settlement System Administrator fail to agree on the amount of an
          additional payment, the Tariff Operator may refer the matter to the
          Executive Committee which shall determine the same. The relevant Meter
          Operator Party may refer any such decision of the Executive Committee
          to the Director and for the purposes thereof shall be deemed to be
          exercising a Dissentient Pool Member's right of appeal pursuant to and
          in accordance with Clause 13.5. The Settlement System Administrator
          shall send the Executive Committee on request a written report giving
          reasonable details of any such additional payments made or proposed to
          be made.

22.6      Costs beyond SSA's control: Payments which are made to Tariff
          Operators in respect of the provision of installation and maintenance
          services in respect of Communications Equipment (whether or not
          pursuant to or in addition to the relevant Tariff) and payments for
          communications links shall be a cost beyond the control of the
          Settlement System Administrator.

<PAGE>

22.7      Recovery of costs: All costs and expenses relating to the payment
          arrangements referred to in this Schedule for the installation and
          maintenance of Communications Equipment required for the purposes of
          Stage 1 Settlement, the relevant Tariff or otherwise, including
          payments which are made to Tariff Operators for the provision of
          installation and maintenance services in respect of such
          Communications Equipment, payments for communications links,
          management time and expenses of the Settlement System Administrator
          and the cost of funds borrowed to finance such costs, expenses and
          payments, may be recovered in full by the Settlement System
          Administrator in accordance with the Charging Procedure.

22.8      No agency: No agency relationship (whether express or implied) shall
          be, or be deemed to be, created between any Tariff Operator and the
          Settlement System Administrator or any other person as a result of the
          payments to be made pursuant to this Section 22.

22.9      Tariff Operators:

          (a)       There shall at any point in time be no more than one Tariff
                    Operator in respect of each Stage 1 Metering System or

          Electricity Suppliers and the Scottish PESs according to their
          respective Programme Shares.

2.3       Payment and collection:

          2.3.1     EPFAL shall collect from Public Electricity Suppliers and
                    the Scottish PESs the amounts which they are obliged to pay
                    towards the 1998 Programme Costs and each Public Electricity
                    Supplier and each Scottish PES will be obliged to pay its
                    proportionate share of the 1998 Programme Costs (together
                    with Value Added Tax thereon, if applicable) against receipt
                    of any invoice therefor issued by EPFAL.

          2.3.2     EPFAL shall arrange for collection from each Public
                    Electricity Supplier and each Scottish PES of its
                    proportionate share of the 1998 Programme Costs in such
                    manner as may be agreed by EPFAL with the Public Electricity

                    advance) and Public Electricity Suppliers and the Scottish
                    PESs shall comply with such collection procedures and, in
                    particular, shall make payment within the time period
                    prescribed by such procedures.

          2.3.3     If any Public Electricity Supplier or Scottish PES fails to
                    pay an amount properly due under this Schedule within
                    fifteen (15) days of the due date for such payment (such
                    Public Electricity Supplier or Scottish PES being a

                    allocated to the defaulting Non-paying Funder are
                    disregarded) and EPFAL shall accordingly be entitled to

                    EPFAL shall advise each Pool Member of the amount payable by

                    shall pay the amount advised in the relevant invoice within
                    fifteen (15) days after the invoice date.

                    instituting any action or proceedings in any court to
                    enforce payments due to it pursuant to this Section. Upon
                    receipt of any notice under this paragraph 2.3.5, EPFAL will
                    as soon as practicable notify the Executive Committee, all
                    Pool Members and the Director. The provisions of sub-section

                    notify the Executive Committee, the remaining Pool Members
                    and the Director, and the Executive Committee shall convene
                    and cause to be convened a general meeting of Pool Members
                    as soon as possible thereafter, which meeting will determine
                    whether any further 1998 Programme Costs shall be incurred.

          2.3.7     The provisions of paragraphs 15.2.4, 15.2.5 and sub-section

                    mutandis in respect of all payments required to be made
                    pursuant to this Section 2.

2.4       Accrued Costs: As soon as reasonably practicable, but in any event no
          later than 1st April, 1997, the Pool Members will pay each other such
          sums as will ensure that all Accrued Costs have effectively been paid
          for or reimbursed only by Public Electricity Suppliers and Scottish

          3.4.2     Prior to approving any further work packages after 15th
                    July, 1996, undertaking or commissioning any work in respect

                    the Steering Group shall submit one or more Funding Tranches
                    to the Steering Group (with a copy to all PES Nominees) at
                    least 5 working days in advance of any meeting of the
                    Steering Group, for approval. Each Funding Tranche shall

                    undertaken and a budget of all costs associated with that
                    work, together with a comparison of all its elements against
                    the Programme Budget (or, if the Programme Budget shall not
                    then have been agreed, against the planned budget). Any
                    amount to be reimbursed in respect of costs incurred in
                    relation to work packages approved in the period between
                    31st March, 1996 and 15th July, 1996 shall also be the

                    Steering Group at least five working days in advance of a
                    meeting of the Steering Group. Each such Funding Tranche
                    shall contain details of the scope of the work undertaken
                    and details of the costs associated with it.

          3.4.3     At each meeting of the Steering Group, the Steering Group
                    shall resolve whether to approve Funding Tranches duly
                    submitted to it in accordance with paragraph 3.4.2, and,
                    subject to any appeal to Public Electricity Suppliers, any
                    Funding Tranche so approved will become an Approved Funding
                    Tranche. Notwithstanding the decision taken, any Public
                    Electricity Supplier or any member of the Steering Group
                    appointed by a member of the Executive Committee appointed
                    by Public Electricity Suppliers may, within 5 working days
                    of the resolution of the Steering Group, by notice in
                    writing to the Steering Group, appeal the matter to be
                    considered by Public Electricity Suppliers under sub-section
                    7.2. If the Public Electricity Suppliers then resolve to
                    approve the Funding Tranche, it shall become an Approved
                    Funding Tranche. If the matter has been appealed and Public
                    Electricity Suppliers do not so approve it, the Funding
                    Tranche shall not be an Approved Funding Tranche.

          3.4.4     As soon as the Programme Board becomes aware that the cost
                    of any work carried out pursuant to any Approved Funding
                    Tranche is likely to exceed the budget considered by the
                    Steering Group in paragraph 3.4.2 above, it shall forthwith
                    prepare a revised budget and deliver it to the Steering
                    Group, at which point the Steering Group and, if necessary,
                    the Public Electricity Suppliers, will follow the procedure
                    set out in paragraphs 3.4.2 and 3.4.3 in considering whether
                    to authorise the continuation of work under the Approved
                    Funding Tranche, in accordance with such revised budget. If
                    (a) the Steering Group does not resolve to approve the
                    revised budget, in accordance with paragraph 3.4.2 or (b)
                    after referral to Public Electricity Suppliers in accordance
                    with sub-section 7.2 they resolve not to approve the revised
                    budget, then the relevant

<PAGE>

                    1998 Sub-Committee shall undertake no work to implement the
                    Approved Funding Tranche which would lead to the cost of
                    implementing the Approved Funding Tranche exceeding the
                    original budget. If the revised budget is approved in
                    accordance with paragraph 3.4.2 or, as the case may be,
                    sub-section 7.2, the cost of that Approved Funding Tranche
                    will be adjusted accordingly.

          3.4.5     Any Steering Group member may by reasonable notice request
                    such information of the Chief Executive or the Programme
                    Board as may be reasonably required to assess the
                    performance of the 1998 Programme against the Programme
                    Budget and Approved Funding Tranches, it being understood
                    that the Chief Executive and the Programme Board shall not
                    be required to comply with any such information request
                    unless it is made by 3 or more members of the Steering
                    Group.

          3.5       Voting: Any question or matter considered by the Steering
                    Group shall be resolved by a simple majority of votes of
                    members of the Steering Group.

          addition to, deletion from or other change to the Operational
          Framework by or on behalf of Pool Members shall be made only with the
          prior approval of Pool Members in general meeting.

4.2       Effect on 1998 Programme Costs: If any addition to, deletion from or
          other change to the Operational Framework may lead to an increase in
          the 1998 Programme Costs then, unless such addition, deletion or other
          change has been approved by the Public Electricity Suppliers in
          writing or in separate general meeting, the proposed addition,
          deletion or other change shall not take effect unless Pool Members so
          resolve (in which case any costs incurred as a result of the addition,
          deletion or other change in question shall not be 1998 Programme
          Costs).

          shall be an appointee of all Pool Members other than Public
          Electricity Suppliers, and the other three shall be appointees of the
          Public Electricity Suppliers.

          Tranches in paragraphs 3.4.2 and 3.4.3, save that if either the
          Steering Group or Public Electricity Suppliers do not approve the
          draft programme budget, they shall notify the

<PAGE>

          Programme Board of any areas requiring revision and the Programme
          Board shall, as soon as reasonably practicable after such
          notification, re-submit the draft programme budget to the Steering
          Group. Once the draft programme budget is approved it shall be the

          Programme Costs have effectively been paid for according to those
          amended Programme Shares. Any necessary adjustments as between the
          Public Electricity Suppliers and the Scottish PESs in respect of any
          reimbursements made pursuant to sub-sections 8.3 and 8.4 shall also be
          made.

          a Public Electricity Supplier and the Public Electricity Supplier
          retaining the other part shall have such PES Votes and Programme
          Shares as the Director shall determine. Any successor to part only of
          the authorised supply area (as such term is defined in the PES Licence
          of the relevant Scottish PES) of a Scottish PES and the Scottish PES
          retaining the other part shall have such Programme Shares as the
          Director shall determine.

          8.        RECOVERY OF 1998 PROGRAMME COSTS

8.1       Calculation of Aggregate Charging Limit: The Aggregate Charging Limit
          shall be calculated in the following manner:-

          8.1.1     if Total 1998 Programme Costs are less than the Lower Limit
                    then:-

                               LL-T1998 PC
                    ACL = LL - ----------- + FC
                                    2

          8.1.2     if Total 1998 Programme Costs are equal to or greater than
                    the Lower Limit and less than or equal to the Upper Limit
                    then:-

<PAGE>

                    ACL = T1998 PC + FC; and

          8.1.3     if Total 1998 Programme Costs are greater than the Upper
                    Limit then:-

                               T1998 PC - UL
                    ACL = UL + ------------- + FC
                                     2

          in each case, where, subject to the provisions set out below:-

          the Lower Limit ("LL") = (pound)43,500,000;

          the Upper Limit ("UL") = (pound)53,500,000; and

          the Total 1998 Programme Costs ("T1998 PC") = the aggregate amount of
          1998 Programme Costs allocated to Public Electricity Suppliers in
          England and Wales according to their respective Programme Shares,

          save that if, as a result of any addition to, deletion from or other
          change to the Operational Framework and/or the adoption of Approved
          Funding Tranches pursuant to sub-section 3.4 or Section 7 outside the
          scope of the Operational Framework, the Total 1998 Programme Costs are
          changed by any amount in excess of (pound)50,000 then, subject to
          prior approval by the Director, both the Lower Limit and the Upper
          Limit shall be adjusted by the amount of such change.

8.2       Recovery of 1998 Programme Costs from Suppliers:

          8.2.1     As soon as reasonably practicable after the Implementation
                    Date, the Executive Committee shall determine the aggregate
                    amount recoverable by Public Electricity Suppliers in
                    accordance with this sub-section, on the basis of the
                    following formula:-

                          RACL = ACL x (60 - a)
                                        ------
                                         (60)

                    where:-

                    RACL is the aggregate principal amount so recoverable;

                    ACL is the aggregate charging limit determined in accordance
                    with sub-section 8.1; and

                    a is the figure in months by which the Implementation Date
                    is delayed after 1st April, 1998 other than for an Approved
                    Reason.

                    For the purpose of this paragraph and paragraph 8.2.8, ACL
                    shall be determined on the basis of the then latest
                    available estimate of Total 1998 Programme Costs (if the
                    final actual figure for such costs has not then been
                    ascertained).

<PAGE>

          8.2.2     As soon as reasonably practicable after the Implementation
                    Date (or if that date is not the first day of a Quarter, the
                    first day of the next following Quarter) and thereafter
                    after the beginning of each Quarter during the 1998
                    Programme Recovery Period, the Executive Committee shall
                    determine the Quarterly 1998 Programme Amount in respect of
                    the Quarter beginning on the Implementation Date (or, if not
                    the first day of a Quarter, the first day of the next
                    following Quarter) or (as the case may be) in respect of the
                    relevant later Quarter, in accordance with the following
                    formula:-

                                       PACL x r
                          Q1998PA = ---------------
                                    (1 - (1 + r)-L)

                    where:-

                    r is the rate (expressed as a quarterly rate) determined by
                    the Executive Committee to be the time weighted average of
                    the Base Rates prevailing during the preceding Quarter;

                    L is the remaining part of the 1998 Programme Recovery
                    Period (specified in Quarters) as at the beginning of the
                    relevant Quarter save that (if the Implementation Date
                    occurs on a date which is not the first day of a Quarter)
                    for the purposes of the first such calculation L is the
                    remaining part of the 1998 Programme Recovery Period
                    (specified in Quarters) as at the end of the Quarter in
                    which the Implementation Date occurs;

                    PACL is the remaining portion of the principal amount
                    comprised in RACL not recoverable in respect of previous
                    Quarters; and

                    Q1998PA is the Quarterly 1998 Programme Amount.

          8.2.3     Not less than sixteen Business Days before the end of each
                    Quarter which starts during the 1998 Programme Recovery
                    Period, the Executive Committee shall notify each Supplier
                    of the Quarterly 1998 Programme Charge payable by it in
                    respect of that Quarter, which shall be determined in
                    accordance with the following formula:-

                          Q1998PC = Q1998PA x (C1998MWH / TC1998MWH)

                    where:-

                    C1998MWH is the Chargeable 1998 MWh for the Supplier;

                    TC1998MWH is the aggregate of Chargeable 1998 MWh for all
                    Suppliers;

                    Q1998PC is the Quarterly 1998 Programme Charge for the
                    Supplier; and

                    Q1998PA is the Quarterly 1998 Programme Amount for that
                    Quarter.

<PAGE>

          8.2.4     The Executive Committee shall determine the Chargeable 1998
                    MWh ("C1998 MWH") for each Supplier in respect of a Quarter
                    as the sum of the Supplier NHH MWh for the preceding Quarter
                    and the Supplier HH MWh for that preceding Quarter. For this
                    purpose:-

                    (a)       the Supplier NHH MWh in respect of a Supplier
                              shall be the number of MWh supplied by that
                              Supplier during the relevant preceding Quarter in
                              respect of premises with Non Half Hourly Metering
                              Systems (not being 100kW Premises); and

                    (b)       the Supplier HH MWh in respect of a Supplier shall
                              be the number of MWh supplied by that Supplier
                              during the relevant preceding Quarter in respect
                              of premises with Half Hourly Metering Systems (not
                              being 100kW Premises).

          8.2.5     In making any determination pursuant to paragraph 8.2.4 or
                    (as the case may be) paragraph 8.2.8, the Executive
                    Committee shall take into account the most recent
                    information received by it from PESs, the Settlement System
                    Administrator and the Initial Settlement and Reconciliation
                    Agent as at the thirtieth day before the end of the relevant
                    Quarter in which the determination falls to be made. The
                    Executive Committee shall be entitled, in the absence of
                    manifest error and in the absence of information to the
                    contrary derived from the ISRA System or provided by the
                    Settlement System Administrator:-

                    (a)       to assume that Metering Systems registered in ERS
                              relate to 100kW Premises;

                    (b)       to assume that all Non Half Hourly Metering
                              Systems relate to premises other than 100kW
                              Premises; and

                    (c)       to rely on information provided by a Supplier
                              pursuant to paragraph 8.2.6 as to its Supplier HH
                              MWh.

          8.2.6     For the purposes of paragraph 8.2.4 (unless otherwise agreed
                    by the Executive Committee) each Supplier shall inform the
                    Executive Committee in writing, no later than 30 days before
                    the end of each Quarter which starts during the 1998
                    Programme Recovery Period, of the number of MWh supplied by
                    it to premises with Half Hourly Metering Systems, not being
                    100kW Premises, during the preceding Quarter.

          8.2.7     Each Supplier shall pay, no later than the penultimate
                    Business Day of each Quarter during the 1998 Programme
                    Recovery Period, the Quarterly 1998 Programme Charge for the
                    Quarter notified to it by the Executive Committee in
                    accordance with paragraph 8.2.3. Any such payment shall be
                    made to EPFAL (or as otherwise directed by the Executive
                    Committee) in sterling in cleared funds in full without set
                    off or counter claim, withholding or deduction of any kind
                    whatsoever but without prejudice

<PAGE>

                    to any other remedy. All charges under this Section are
                    exclusive of United Kingdom Value Added Tax which shall be
                    added to such charges, if applicable.

          8.2.8     The Executive Committee:-

                    (i)       shall from time to time recalculate RACL on the
                              basis of the then latest estimated or (as the case
                              may be) actual Total 1998 Programme Costs and ACL;

                    (ii)      shall from time to time recalculate the Chargeable
                              1998 MWh and Supplier NHH MWh and Supplier HH MWh
                              for earlier Quarters on the basis of the then
                              latest available information (including
                              information provided by Suppliers pursuant to
                              paragraph 8.2.6) and as if references in paragraph
                              8.2.4 to the preceding Quarter were references to
                              the Quarter in respect of which the relevant
                              calculation falls to be made;

                    (iii)     may from time to time following an adjustment to
                              RACL, recalculate PACL such that any adjustment to
                              charges payable will not be applied
                              retrospectively across all Accounting Periods in
                              the 1998 Programme Recovery Period; and

                    (iv)      shall from time to time make such adjustments as
                              may be necessary (and, where relevant, apply
                              interest at the Base Rate or at such rate as shall
                              be set from time to time by the Executive
                              Committee in respect of any adjustments made as a
                              result of a recalculation in accordance with
                              paragraph (i)) from time to time to account for
                              any differences between payments made and the
                              payments which should have been made in the light
                              of such recalculations.

                    In the absence of manifest error and subject as provided in
                    paragraph 8.2.11, no adjustment shall fall to be made in
                    respect of charges payable by Suppliers pursuant to this
                    sub-section as a result of revised information (other than
                    as to Total 1998 Programme Costs, ACL and interest rates and
                    the final runs of Stage 1 Settlement and Stage 2 Initial
                    Settlement Runs in respect of all Settlement Periods in a
                    Quarter) becoming available to the Executive Committee after
                    it has made a determination pursuant to paragraph 8.2.4.

          8.2.9     In the event of any dispute regarding charges payable under
                    this Section, no Supplier may withhold payment of any
                    invoiced amount but may refer such dispute to arbitration in
                    accordance with Clause 83.

          8.2.10    If any amount due under this Section is not received on the
                    due date, the Supplier required to pay such amount shall pay
                    interest to EPFAL (or as otherwise directed by the Executive
                    Committee), for the account of the persons entitled to
                    receive the amount in default, on such amount from and
                    including the date of default to the date of actual

<PAGE>

                    payment (as well after as before judgment) at the Default
                    Interest Rate from time to time during such period of
                    default.

          8.2.11    Any Supplier which is a Supplier for part only of any
                    Quarter shall pay charges on an interim basis of such amount
                    as the Executive Committee estimates to be reasonable for
                    such Quarter. Adjustments to charges on all Suppliers as a
                    result of existing Suppliers leaving or new Suppliers
                    joining will be made in such manner as the Executive
                    Committee shall determine.

          8.2.12    The Executive Committee may, in its discretion, determine
                    the charges to be payable by Suppliers pursuant to this
                    sub-section 8.2 according to such transitional arrangements
                    as it considers appropriate from time to time having regard
                    to the availability of information concerning Half Hourly
                    Metering Systems or (as the case may be) Non Half Hourly
                    Metering Systems, premises which are not 100kW Premises and
                    quantities of energy attributable to particular Suppliers.
                    Without prejudice to the foregoing, the Executive Committee
                    shall establish reasonable transitional arrangements for the
                    period from the Implementation Date until the information
                    referred to in paragraph 8.2.4 is available in respect of
                    all GSP Groups and Suppliers shall pay the charges
                    established in accordance with those arrangements.

          8.2.13    Whenever the Executive Committee determines that an
                    adjustment is necessary pursuant to this sub-section 8.2,
                    the Suppliers and/or former Suppliers concerned shall be
                    required to pay such additional amounts or be entitled to
                    such reimbursement as may be determined by the Executive
                    Committee by an adjustment to charges in respect of the
                    relevant earlier Quarter or (as the case may be) the then
                    current Quarter.

          8.2.14    No reimbursement shall be made to a leaving Supplier in
                    respect of any month until the necessary adjustments (if
                    any) have been made to take into account, following the end
                    of the Accounting Period in which that Party is to cease to
                    be a Supplier, the final run of Stage 1 Settlement and the
                    Stage 1 Initial Settlement Run in respect of all Settlement
                    Periods during which that Party traded as a Supplier.

          8.2.15    The Executive Committee shall not be required to issue any
                    invoice, nor to pay an amount by way of reimbursement (nor
                    issue any credit note in respect of any such reimbursement),
                    to a Supplier if the aggregate amount otherwise payable by,
                    or to be reimbursed by, that Pool Member pursuant to this
                    sub-section is less than the minimum from time to time
                    determined by the Executive Committee. Where the minimum
                    applies, a Supplier shall remain liable for any amounts
                    payable by it but shall not be required to make any payment
                    until such time as the amount in question is included in an
                    invoice. Paragraph 8.2.10 shall be construed accordingly.

8.3       Reimbursement to Public Electricity Suppliers:

          8.3.1     The amounts recovered from Suppliers pursuant to sub-section
                    8.2 in respect of a Quarter shall be distributed among the
                    PESs on the last Business Day of that Quarter according to
                    their proportionate shares of "PES Votes" specified in
                    column 3 of sub-section 6.3. Any amounts received late from
                    Suppliers shall be distributed on the same basis as soon as
                    reasonably practicable following their receipt. The
                    Executive Committee shall make such arrangements with EPFAL
                    or otherwise as it determines to be necessary for the
                    collection of amounts payable pursuant to sub-section 8.2
                    and the payment of such amounts pursuant to this sub-section
                    8.3.

          8.3.2     Following the end of each Quarter the Executive Committee
                    shall monitor the amounts due to each PES since the
                    Implementation Date and the amounts paid, in each case in
                    accordance with the provisions of this Section.

          8.3.3     After the expiry of the 1998 Programme Recovery Period the
                    Executive Committee shall produce a statement showing the
                    amounts due to each PES and the amounts paid, in each case
                    in accordance with the provisions of this Section. The
                    Executive Committee shall review the materiality of any
                    differences and propose a mechanism for resolving them.

8.4       Recovery by Scottish PESs: Scottish PESs shall be entitled to recover
          from third parties their respective contributions towards the 1998
          Programme Costs in accordance with the terms of their agreement with
          the Director (if any).

9.        SCHEDULE 22 CEASING TO HAVE EFFECT

Without prejudice to any accrued rights or liabilities, the provisions of this
Schedule 22 shall cease to have effect on the date following that on which the
final payment has been made to the last Public Electricity Supplier to be
reimbursed its due proportion in respect of 1998 Programme Costs and Financing
Costs pursuant to Section 8.

1.        INTERPRETATION

          the context otherwise requires, words and expressions defined in this

          the provisions of this Schedule and the other provisions of this
          Agreement (other than Schedule 22) insofar as concerns the
          relationship of the Scottish Settlements Arrangements to the 1998
          Programme or the Operational Framework, the provisions of this
          Schedule shall, unless otherwise expressly stated, prevail. In the
          event of any other inconsistency or conflict between the provisions of
          this Schedule and the other provisions of this Agreement, such other
          provisions shall prevail.

          with the Scots Subsidiary Documents insofar as applicable to such
          Party. The Executive Committee shall provide copies of the Scots

          be entitled to attend, speak or vote at the relevant meeting or
          otherwise to participate in the decision taking processes and the
          voting procedures shall be adjusted in such manner as the Pool
          Chairman in his sole discretion shall see fit to make allowance for

          3.4.1     The obligations of the Scottish PESs contained in this
                    Section 3 shall be in addition to and independent of every
                    other security which any of the Combined Members may at any
                    time hold in respect of any obligations of Scottish

                              this paragraph 3.4.3, might operate to discharge,
                              impair or otherwise affect any of the obligations
                              of either of the Scottish PESs herein contained or
                              any of the rights, powers or remedies conferred
                              upon the Combined Members by this Schedule or any
                              of the Scots Subsidiary Documents or by law.

          3.4.4     Any settlement or discharge between the Scottish PESs and
                    Scottish Settlements shall be conditional upon no security
                    or payment to the Combined Members or any of them by the
                    Scottish PESs or either of them or Scottish Settlements or
                    any other person on behalf of the Scottish PESs or, as the
                    case may be, Scottish Settlements being avoided or reduced
                    by virtue of any provisions or enactments relating to
                    bankruptcy, insolvency, liquidation or similar laws of
                    general application for the time being in force and, if any
                    such security or payment is so avoided or reduced, the
                    Combined Members or the relevant one of them shall be
                    entitled to recover the value or amount of such security or
                    payment from the Scottish PESs subsequently as if such
                    settlement or discharge had not occurred.

          3.4.5     None of the Combined Members shall be obliged before
                    exercising any of the rights, powers or remedies conferred

                    (C)       to make or file any claim or proof in a winding-up
                              or dissolution of Scottish Settlements; or

                    (D)       to enforce or seek to enforce any other security
                              taken in respect of any of the obligations of
                              Scottish Settlements under this Schedule or any of
                              the Scots Subsidiary Documents.

          3.4.6     The Scottish PESs agree that, until all amounts which may be
                    or become payable by Scottish Settlements under or in
                    connection with this Schedule and the Scots Subsidiary
                    Documents have been irrevocably paid in full, neither of the

                              or agent on its behalf); or

                    (C)       receive, claim or have the benefit of any payment,
                              distribution or security from or on account of

                              Software together with all copies of them in the
                              Scots Licensees' possession or control and (if any
                              Scots Licensee fails to do so) the Executive
                              Committee or its agent shall have the right to
                              enter such Scots Licensee's premises and repossess
                              the Required Documentation and the Pool 1998

                    (iii)     the Scots Licensees will destroy any programme or

                              memory device which is derived from the Required
                              Documentation and/or the Pool 1998 Software and is

          (C)       Termination of the Scots 1998 Licence will not release any

                    effective or continue to be effective on or after the
                    termination of the Scots 1998 Licence.

4.5       Scope of Scots 1998 Licence:

          (A)       The Scots Licensee shall have the right to use the Required
                    Documentation and the Pool 1998 Software only for the
                    purposes of the Scottish Settlements Arrangements and shall
                    not use the Required Documentation or the Pool 1998 Software
                    in any other way.

          (B)       The Scots Licensee is licensed to copy, develop, alter or
                    modify the whole or any part of the Required Documentation
                    or Pool 1998 Software or combine it with any other
                    materials, in any such case only for the purposes of the
                    Scottish Settlements Arrangements (the "Developed
                    Material"), but will not permit any other person to do so
                    except for a person at any time under contract to the Scots
                    Licensee to do so (the "Scots Contractor"). The Scots
                    Contractor will not have any more extensive right to use the
                    Required Documentation or the Pool 1998 Software than the
                    Scots Licensee has under this Section 4.

          (C)       The Scots Licensee shall ensure the proper use, supervision,
                    management and control of the Required Documentation and
                    Pool 1998 Software and that the same are properly protected
                    at all times from unauthorised access or use by any person.

          (D)       The Scots Licensee shall keep the Required Documentation and
                    Pool 1998 Software confidential and shall only authorise
                    access or disclosure to those persons or categories of
                    person for the time being and from time to time listed or
                    referred to in Scots Subsidiary Document 6 and to whom
                    access or disclosure is strictly necessary to enable the
                    Required Documentation or Pool 1998 Software



<PAGE>

                    to be used in accordance with this Section 4. The Scots
                    Licensee shall ensure that each such person is aware of the
                    confidential nature of the Required Documentation and Pool
                    1998 Software and keeps them confidential. This paragraph
                    shall not apply to any part of the Required Documentation
                    and Pool 1998 Software which has entered the public domain
                    other than as a result of any breach of agreement or duty.

          (E)       The following obligations apply in relation to the use of
                    source code:-

                    (i)       all copies of any source code which is part of the
                              Required Documentation or Pool 1998 Software will
                              be individually numbered and the existence and
                              location of each such copy shall be notified by
                              the Scots Licensee to the Executive Committee; and

                    (ii)      the Scots Licensee shall notify the Executive
                              Committee of details of each of its employees and
                              those of any Scots Contractor who will have access
                              to the source code and, unless otherwise agreed by
                              the Executive Committee, shall ensure that each
                              such employee will (before access) enter into an
                              individual confidentiality agreement in a form
                              approved by the Executive Committee. The Scots
                              Licensee shall provide the Executive Committee
                              with an original copy of each such agreement and
                              will ensure that, unless otherwise agreed by the
                              Executive Committee, no employee of the Scots
                              Licensee or any Scots Contractor has access to the
                              source code except for those employees whose
                              details have been notified to the Executive
                              Committee and are bound by such agreements.

          (F)       The Scots Licensee shall immediately bring to the attention
                    of the Executive Committee any infringement or suspected
                    infringement by any third party of any rights in the
                    Required Documentation or the Pool 1998 Software of which it
                    becomes aware and shall, at the Executive Committee's
                    request and against payment of its reasonable costs and
                    expenses, take or join Pool Members in taking such action as
                    they may require for the purpose of protecting such rights.

          (G)       Pool Members are not obliged under the Scots 1998 Licence to
                    develop, maintain or enhance the Required Documentation or
                    the Pool 1998 Software.

          (H)       The Scots Licensees agree to grant Pool Members a perpetual,
                    royalty-free, non-exclusive licence to use and exploit the
                    Developed Material mutatis mutandis on the same terms as the
                    Scots 1998 Licence (the "Scots Licence-Back") provided
                    that:-

                    (i)       the Scots Licensees shall be entitled by notice to
                              the Executive Committee to designate particular
                              parts of the Developed Material as having
                              commercial value where the Scots Licensees decide
                              reasonably



<PAGE>

                              and in good faith that a material cost has been
                              incurred in developing the same. In any such case
                              the Scots Licence-Back shall be subject to the
                              agreement between the Scottish Licensees on the
                              one hand and the Other Pool Members on the other
                              hand of a reasonable royalty reflecting an
                              appropriate proportion of such cost (such
                              agreement not to be unreasonably withheld or
                              delayed); and

                    (ii)      the Scots Licensees shall not be obliged to
                              license any part of the Developed Material where
                              the Scots Licensees believe reasonably and in good
                              faith that the same would confer a significant
                              competitive benefit on the Other Pool Members and
                              for that reason should not be licensed to them.

          (I)       The Scots Licensees shall notify the Executive Committee at
                    least once every six months of all Developed Material that
                    has been produced during the preceding six month period.

4.6       Reporting requirement: The Scots Licensee shall supply the Executive
          Committee from time to time on request with a statement signed by a
          director of the Scots Licensee which certifies that the Required
          Documentation and Pool 1998 Software is being used only in accordance
          with this Section 4.

4.7       Access: The Scots Licensee shall grant the Executive Committee or its
          nominee access upon reasonable prior notice to the Scots Licensee's
          premises in order to audit the use of the Required Documentation and
          Pool 1998 Software.

4.8       Indemnity: The Scottish PESs and Scottish Settlements shall jointly
          and severally indemnify and keep indemnified the Combined Members and
          each of them on demand against all direct losses, costs, damages,
          expenses, liabilities and claims suffered or incurred by any of the
          Combined Members arising out of or in relation to any Scots Licensee's
          breach of any of its obligations under this Section 4.

4.9       Further licences: Pool Members agree that the Scottish PESs and
          Scottish Settlements shall be entitled to a licence to use the EAC/AA
          System and the NHH Data Aggregation System on terms and conditions
          comparable to those on which a licence to use the same is offered to
          Public Electricity Suppliers generally.

5.        SCOTTISH REQUIREMENTS AND THE RELEVANT 1998 SYSTEMS

5.1       Change to the Operational Framework: The provisions of Schedule 22
          shall govern any addition to, deletion from or other change to the
          Operational Framework.

5.2       Change control: Subject to sub-section 5.1, the provisions of Scots
          Subsidiary Document 3 shall govern the control of a change (which
          shall include any request by the Scottish



<PAGE>

          PESs or Scottish Settlements for an additional requirement) to the
          Relevant 1998 Systems insofar as the change concerns a change to the
          Relevant 1998 Systems requested by the Scottish PESs or Scottish
          Settlements for the purposes of the Scottish Settlements Project.

5.3       Disputes over change control: If pursuant to any Scots Subsidiary
          Document this sub-section is stated to apply and the relevant Systems
          Requirement Request relates to changes in the functionality of the
          Relevant 1998 Systems then, notwithstanding the provisions of Part III
          of this Agreement, the determination of the Executive Committee in
          relation to the matter shall be final, conclusive and binding and
          there shall be no right of referral to Pool Members in general meeting
          nor any right of appeal to the Director and each Party expressly,
          irrevocably and unconditionally waives all such rights of referral and
          appeal.

5.4       Other changes to the 1998 Programme: Pool Members acknowledge that, in
          respect of any change to the 1998 Programme required by the Scottish
          PESs (or, as the case may be, Scottish Settlements) for the purposes
          of the Scottish Settlements Arrangements which does not fall to be
          dealt with by sub-section 5.1 or 5.2, the Scottish PESs (or, as the
          case may be, Scottish Settlements) shall have the right, and shall be
          obliged, to use the change control procedure established under the
          1998 Programme and the costs of any such change and the change control
          charges shall be borne by the Scottish PESs (or, as the case may be,
          Scottish Settlements) as if they were charges under sub-section 9.1
          or, as the case may be, 9.2.

6.        1998 CONTRACTORS' SERVICES

6.1       Retaining 1998 Contractors:

          (A)       If the Scottish PESs (or either of them) or Scottish
                    Settlements wish to employ or retain any 1998 Contractor to
                    undertake work or provide services in relation to the
                    Scottish Settlements Project which is or are broadly
                    equivalent to the work or services which any 1998 Contractor
                    is or are performing in relation to the 1998 Programme for
                    the benefit of all Pool Members (including, for the
                    avoidance of doubt, the development of the EAC/AA System),
                    the Scottish PESs or (as the case may be, Scottish
                    Settlements) shall procure that, before they or it enter
                    into a contract or arrangement with such 1998 Contractor for
                    such work or services (the "Scots ------ Contract"), the
                    1998 Contractor (or, where the 1998 Contractor is a
                    sub-contractor, the principal 1998 Contractor) shall, unless
                    the Executive Committee otherwise resolves upon application
                    made by the Scottish PESs (or, as the case may be, Scottish
                    Settlements), confirm in writing to Pool Members (or a
                    nominee on their behalf) in the terms set out in sub-section
                    6.1(B).

<PAGE>

                    other contracts and arrangements of the relevant 1998
                    Contractor (including any contacts or arrangements relating
                    to the 1998 Programme), will not affect adversely the
                    performance of such 1998 Contractor's obligations to Pool
                    Members under its contract or arrangement with them (or
                    their nominee) or cause or otherwise result in such 1998
                    Contractor being in breach of any of its obligations to Pool
                    Members under its contract or arrangement with them (or
                    their nominee), to the intent that such confirmation shall
                    constitute a legally binding obligation of such 1998
                    Contractor under such contract or arrangement with Pool
                    Members (or their nominee).

6.2       List of 1998 Contractors: The Executive Committee shall provide the
          Scottish PESs from time to time with an up-to-date list of all the
          1998 Contractors and a summary of the work or services that they have
          been retained to perform.

6.3       No restriction: Nothing in this Section 6 shall preclude or restrict

          any person who is not a 1998 Contractor to perform the work or
          services referred to in sub-section 6.1 or from employing or retaining
          any person who is a 1998 Contractor to perform work or services in the
          period after completion of the 1998 Programme.

6.4       Liaison: The Scottish PESs (or, as the case may be, Scottish
          Settlements) and the Other Pool Members (in each case through their
          appointed representatives) shall liaise on a regular basis (usually
          monthly) on the planning and manpower requirements for the work and
          services referred to in sub-section 6.1.

7.        RELATIONSHIPS

7.1       Expert Groups: The Scottish PESs (or, as the case may be, Scottish
          Settlements) shall have the right on the terms and subject to the
          conditions set out in Scots Subsidiary Document 5 to attend meetings

                    shall address all such communications to the Programme
                    Liaison Officer (in the form, where appropriate, of a
                    Systems Requirement Request) provided that the Scottish PESs
                    and Scottish Settlements shall have the right to contact or
                    communicate directly with (and in the case of (ii) and (iii)

<PAGE>

                    with or give instructions to) a 1998 Contractor with respect
                    to any such matter (but subject to Section 4):-

                    (i)       in the case and for the purposes of an inspection
                              approved by the Programme Board (or otherwise
                              determined to be made on appeal from the decision
                              of the Programme Board) in accordance with
                              paragraph (C) below;

                    (ii)      in the circumstances and for the purposes
                              described in sub-section 6.1; and

                    (iii)     in the case of a determination of the Executive
                              Committee that, in the reasonable opinion of the
                              Scottish PESs, is unfavourable to the Scottish
                              PESs (or, as the case may be, Scottish
                              Settlements) in a significant respect where,
                              pursuant to sub-section 5.3, the determination of
                              the Executive Committee is final (but then only in
                              relation to those matters which were the subject
                              of that determination and on the terms set out in
                              sub-section 6.1),

                    provided that nothing in this paragraph (A) shall prevent or
                    restrict either of the Scottish PESs or Scottish Settlements
                    from contacting or communicating directly with any 1998
                    Contractor with respect to work or services required for the
                    production of Developed Material.

          (B)       The Scottish PESs and Scottish Settlements shall not
                    interfere with the performance by any 1998 Contractor of any
                    of its obligations in connection with the 1998 Programme.

          (C)       (i)       If the Scottish PESs or Scottish Settlements have
                              a material concern that the progress of work on
                              the 1998 Programme is such as to cause the date
                              for completion of the Scottish Settlements Project
                              to be delayed, the Scottish PESs and Scottish
                              Settlements shall have the right to request
                              inspection of work on the 1998 Programme in
                              accordance with paragraphs (C)(ii) and (iii)
                              below.

                    (ii)      An application for inspection by the Scottish PESs
                              or Scottish Settlements referred to in paragraph
                              (C)(i) shall be made to the Programme Board with
                              reasons in support and details of the form of
                              inspection required (it being understood that any
                              such inspection will normally be conducted under
                              the supervision of the Programme Board). The
                              Programme Board will give due consideration to any
                              such application and will notify the Scottish PESs
                              (or, as the case may be, Scottish Settlements) of
                              its determination whether the case for such an
                              inspection has been made

<PAGE>

                              and, if a case for an inspection has been made,
                              the form that such inspection is to take.

                    (iii)     If the Programme Board determines that a case for
                              an inspection has been made, Pool Members shall
                              use all reasonable endeavours to facilitate the
                              carrying out of such inspection in accordance with
                              the determination of the Programme Board.

                    (iv)      If the Programme Board determines that a case for
                              an inspection has not been made, the Scottish PESs
                              in their capacity as Pool Members shall have the
                              right to refer the matter to the Executive
                              Committee for determination and to appeal such
                              determination pursuant to the terms of this
                              Agreement.

          (D)       The Pool Members shall arrange for the Scottish PESs (or, as
                    the case may be, Scottish Settlements) to receive copies of
                    each 1998 Contractor's periodic progress reports to the
                    Programme Board or the 1998 Programme project boards on
                    matters concerning the 1998 Programme after deletion of any
                    information in or accompanying any such report which is
                    reasonably considered by those administering the 1998
                    Programme to be commercially sensitive.

          (E)       The Scottish PESs (or, as the case may be, Scottish
                    Settlements) shall be entitled at their own cost and expense
                    to attend and witness acceptance testing of the ISRA System
                    and to receive copies of the related test logs as may be
                    reasonably required by the Scottish PESs (or, as the case
                    may be, Scottish Settlements).

8.        NO REPRESENTATION OR LIABILITY

8.1       No representation or warranty: With the exception of the confirmations
          given by the Pool Members in sub-section 4.2(B), none of the Combined
          Members makes or gives any representation or warranty as to the
          suitability or fitness of the Required Documentation or the Pool 1998
          Software for any particular purpose and all conditions, warranties and
          representations whether express or implied as to the Required
          Documentation or the Pool 1998 Software (including as to its quality,
          fitness, operation or use) are excluded to the fullest extent
          permitted by law.

8.2       No reliance: Each of the Scottish PESs (for itself and on behalf of
          Scottish Settlements) hereby acknowledges that it has not been induced
          to enter into the arrangements set out in this Schedule and the Scots
          Subsidiary Documents by, nor has it placed reliance on any prior
          representation or statement (whether oral or in writing) made by, any
          of the Combined Members or the 1998 Contractors.

8.3       Exclusion of certain types of loss: Each of the Scottish PESs (for
          itself and on behalf of Scottish Settlements) hereby acknowledges and
          agrees that, save as provided in sub-

<PAGE>

          section 8.4, in no circumstances will any of the Combined Members be
          liable to either of the Scottish PESs or Scottish Settlements under
          this Schedule or the Scots Subsidiary Documents in contract, tort
          (including negligence or breach of statutory duty) or otherwise for
          loss (whether direct or indirect) of profit, loss of revenue, loss of
          use, loss of contract or loss of goodwill or for any indirect or
          consequential loss or damage whatsoever.

8.4       No exclusion for death or personal injury: Nothing in this Schedule
          shall exclude liability for death or personal injury resulting from
          the negligence of a Party or any of its officers, employees or agents.

8.5       Reasonableness of exclusion: Each of the Scottish PESs (for itself and
          on behalf of Scottish Settlements) acknowledges that it is aware of
          and understands the provisions in relation to liability set out in
          this Section and in particular that, given the level of charges made
          for the provision and use of the Required Documentation and Pool 1998
          Software, it is reasonable for the Combined Members to exclude their
          liability as provided for in this Section.

9.        PAYMENTS

9.1       Charges: The Scottish PESs and Scottish Settlements shall be jointly
          and severally liable to pay to the Other Pool Members in accordance
          with sub-section 9.3:-

                    (if any) as may be agreed from time to time by the Scottish

                    and (ii) the date on which all of the conditions precedent
                    in paragraph 3.2.2 shall have been satisfied in full or
                    shall have been waived by Pool Members in general meeting.

          3.2.2     The conditions precedent referred to in paragraph 3.2.1 are:

                    (i)       the Performance Assurance Board resolves (in its
                              absolute discretion) that the PES which owns or
                              operates the Distribution System to which the
                              relevant GSP Group relates has completed the PRS
                              Entry Process for such GSP Group or Pool Members
                              have resolved that such PES has completed that PRS

                              operates the Distribution System to which the
                              relevant GSP Group relates has completed the
                              Supplier Entry Process for such GSP Group or Pool
                              Members have resolved that such PES has completed
                              that Supplier Entry Process to Pool Members'
                              satisfaction,

                    and, in either case, such resolution has taken effect.

3.3       Postponement of GSP Group Implementation Date: The Performance

          may be) this sub-section to be the GSP Group Implementation Date for
          the relevant GSP Group, to postpone such GSP Group Implementation Date
          to such later date as the Performance Assurance Board shall determine
          if it considers that circumstances justify such a postponement. If

          GSP Group, the right to postpone the GSP Group Implementation Date for
          that GSP Group shall be exercisable, at any time before the date
          determined in accordance with sub-section 3.1 or (as the case may be)
          this sub-section, by Pool Members in general meeting if Pool Members
          in general meeting consider that circumstances justify such a
          postponement. Upon the Performance Assurance Board or (as the case may
          be) Pool Members in general meeting determining to postpone the date

          case with respect to a GSP Group, on and from the GSP Group

          System.

4.7       Referral to the Director:

          4.7.1     The sole and exclusive remedy of an Accredited Person who is

                    Accreditation or the Certification or removal of
                    Certification of its Agency Systems (the "Dissatisfied

                    Director in accordance with this sub-section 4.7 for
                    determination.

                    (b)       set out in its referral to the Director (with
                              reasons in support) the ground or grounds on which
                              the Dissatisfied Accredited Person is making its
                              application to the Director which shall be one or
                              more of the following (and no other):-

                              (i)       that the Performance Assurance Board has
                                        not followed the procedures set out in
                                        this Schedule and Agreed Procedure
                                        AP531; or

                              (ii)      that the Performance Assurance Board has
                                        given undue weight to particular
                                        evidence submitted or to the lack of
                                        particular evidence; or

                              (iii)     that the Performance Assurance Board has
                                        misinterpreted all or some of the
                                        evidence submitted in connection with
                                        such application; or

                              (iv)      that, notwithstanding any restrictions
                                        that Pool Members may place on the
                                        Performance Assurance Board as to how it
                                        is to assess and decide the matter, the
                                        Performance Assurance Board should not
                                        have taken into account the failure by
                                        the Dissatisfied Accredited Person to
                                        satisfy one or more specified
                                        Accreditation Requirements or, as the
                                        case may be, the failure of the


<PAGE>

                                        Dissatisfied Accredited Person's Agency
                                        System(s) to satisfy one or more
                                        Certification Requirements.

          4.7.3     On a valid referral pursuant to paragraph 4.7.1 the Director
                    may either determine the matter himself or, if he thinks
                    fit, refer the matter for determination by an arbitrator
                    appointed by him and, subject to paragraph 4.7.4, the
                    practice and procedure to be followed in connection with any
                    such determination shall be such as the Director may
                    consider appropriate.

          4.7.4     In connection with any referral pursuant to paragraph 4.7.1
                    which the Director determines himself, the Director shall
                    have:-

                    (a)       the right to engage an independent consultant
                              selected by the Director and to take and rely on
                              the advice of such independent consultant; and

                    (b)       the discretion to make a determination that the
                              Dissatisfied Applicant should or should not be or
                              remain Accredited or that its Agency System(s)
                              should or should not be or remain Certified
                              notwithstanding that the ground on which the
                              Dissatisfied Accredited Person has applied to the
                              Director is either the wrong ground or has not
                              been proven.

          4.7.5     The determination of the Director or, as the case may be,
                    the arbitrator pursuant to paragraph 4.7.3 shall be final,
                    conclusive and binding on the Dissatisfied Accredited
                    Person, the Performance Assurance Board and all Pool Members
                    and may include a provision as to the payment in respect of
                    the costs and expenses incurred by the person making the
                    determination. The Dissatisfied Accredited Person, the
                    Performance Assurance Board and all Pool Members shall
                    promptly give effect to any such determination.

          4.7.6     For the avoidance of doubt, neither Clause 83 nor Clause 84

          specified terms or conditions of this Agreement, the Service Lines,

          (in that capacity) who has appointed, or is to appoint, that
          Accredited Person (a "Related Supplier") shall be in breach of this
          Agreement insofar as it fails to comply with its obligations under

          Accredited Person in respect of whom it is a Related Supplier does not
          comply with the Derogated Provision at any time during the period for
          which such Derogation is in effect.


<PAGE>


6.2       Compliance with Derogations: An Accredited Person shall use its best
          endeavours to comply, and a Related Supplier shall (in that capacity)

          conditions of any applicable Derogation for so long as it is in

                            Supplier Responsibilities

1.        INTERPRETATION

Interpretation: In this Schedule, unless the context otherwise requires,
references to a particular Section, sub-section or paragraph shall be a
reference to that Section, sub-section or paragraph of this Schedule.

2.        SUPPLIERS AND SUPPLIER AGENTS

2.1       General: The provisions of this Schedule shall have effect generally
          with respect to certain responsibilities of Suppliers in connection
          with Stage 2 Settlement and with respect to the functions of Meter
          Operators, Data Collectors, Data Aggregators or Meter Administrators
          in relation to Stage 2 Metering Systems. A Supplier may (subject as
          provided in paragraphs 3.2.3, 4.3.3 and 5.3.3), instead of securing
          that a Meter Operator, Data Collector, Data Aggregator or Meter
          Administrator is appointed in relation to any Stage 2 Metering System,
          perform the relevant function or functions itself provided that it is
          and remains Accredited (where applicable), in which event the
          provisions of this Schedule shall apply and be interpreted on the
          basis that the Supplier shall (in its capacity as a Meter Operator,
          Data Collector, Data Aggregator or Meter Administrator) itself perform
          the obligations in respect of which it would otherwise be required to
          ensure compliance by the relevant Supplier Agent.

2.2       Appointment of Supplier Agents: Each Supplier shall, in relation to
          each Stage 2 Metering System in respect of which it has an effective
          registration in a PES Registration Service, secure that the following
          are appointed, and that such appointments are (where applicable)
          recorded in the relevant PES Registration Service, with effect from
          the time when such registration first takes effect and that an
          appointment of each of the following is maintained so long as the
          Supplier remains so registered:-

          2.2.1     unless the Metering System relates to an Unmetered Supply,
                    an Accredited Meter Operator;

          2.2.2     an Accredited Data Collector;

          2.2.3     an Accredited Data Aggregator; and

          2.2.4     if the Metering System relates to an Equivalent Unmetered
                    Supply, a Meter Administrator (who shall be Accredited if
                    applicable).

2.3       Supplier Entry Process: Each Supplier shall ensure that it and each of
          its Supplier Agents who are to be responsible for Metering Systems
          within a GSP Group has satisfied the

<PAGE>

          requirements of the Supplier Entry Process in accordance with the
          relevant Agreed Procedure before any registration of that Supplier in
          respect of a Stage 2 Metering System in the PES Registration Service
          relating to that GSP Group becomes effective.

2.4       Replacement of Supplier Agents:

          2.4.1     Each Supplier may arrange for any Supplier Agent for which
                    it is responsible to be removed from time to time provided
                    that a replacement Supplier Agent shall have been appointed
                    with effect from the date of removal of the removed Supplier
                    Agent. Each Supplier shall ensure that the appointment of a
                    Supplier Agent for which it is responsible shall terminate
                    on withdrawal of the Accreditation (where applicable) of the
                    relevant Supplier Agent.

          2.4.2     Each Supplier shall ensure that there are appropriate
                    arrangements in place in compliance with the relevant
                    Service Lines with each Supplier Agent for which it is
                    responsible from time to time to enable any replacement
                    Supplier Agent for which it is responsible to take over the
                    functions of a Supplier Agent whose appointment has expired
                    or been terminated, including arrangements for the transfer
                    of relevant data to such replacement Supplier Agent.

2.5       Responsibility of Suppliers: Each Supplier shall:-

          2.5.1     be responsible for every act, breach, omission, neglect and
                    failure of each Supplier Agent appointed as referred to in
                    sub-section 2.2 and shall itself comply, and procure
                    compliance by each such Supplier Agent, with the relevant
                    Service Lines, relevant Agreed Procedures, relevant Codes of
                    Practice (in respect of meter operation) and applicable Pool
                    Rules; and

          2.5.2     be entitled, as between itself and the other Pool Members,
                    to agree, amend and substitute the terms (including terms as
                    to charges and payment) of any such appointment as it may
                    think fit.

2.6       Performance Assurance: Each Supplier shall:-

          2.6.1     provide, or procure the provision of, such reports to the
                    Performance Assurance Board as may from time to time be
                    reasonably required in accordance with Agreed Procedure
                    AP532 in order to enable the Performance Assurance Board to
                    review compliance by that Supplier with the requirements of
                    this Schedule and compliance by each Supplier Agent for
                    which that Supplier is responsible with the relevant Service
                    Lines;

          2.6.2     provide the Executive Committee and the Performance
                    Assurance Board with access to all of its records, data and
                    other information (and those of its Supplier Agents) as may
                    reasonably be required by the Executive Committee or (as the


<PAGE>

                    case may be) the Performance Assurance Board to carry out
                    its functions in accordance with Schedule 8 and the Agreed
                    Procedure referred to in paragraph 2.6.1 or otherwise

                    provided; and

                               Unmetered Supplies

1.        INTRODUCTORY

1.1       Unmetered Supplies and this Schedule: The rights and obligations of
          the Parties in relation to Unmetered Supplies shall be as set out in
          this Schedule and the relevant Service Line and Agreed Procedure.

1.2       Inconsistency and conflict: If there is any inconsistency or conflict
          between the provisions of this Schedule and any other provisions of
          this Agreement in relation to Unmetered Supplies, the provisions of
          this Schedule shall prevail.

1.3       Standards of accuracy: The standards of accuracy of data for Unmetered
          Supplies from time to time shall be no worse than those which at such
          time apply generally under this Agreement for metered supplies of
          electricity.

1.4       Load research programmes: The Executive Committee on behalf of Pool
          Members shall have the right at any time and from time to time to
          commission load research programmes in respect of Unmetered Supplies
          to support changes made or proposed to be made to the relevant Service
          Line or Agreed Procedure.

2.        PUBLIC ELECTRICITY SUPPLIERS AND UNMETERED SUPPLIES

2.1       Determination of Unmetered Supplies: A Public Electricity Supplier
          shall determine in relation to supplies of electricity within its
          Authorised Area whether a supply of electricity to a particular
          inventory of Apparatus is to be treated for the purposes of this
          Agreement as an Unmetered Supply provided that, if such supply is
          separately measured and recorded through a Metering System at or near
          to the point of supply to the Customer, the Public Electricity
          Supplier shall not determine that such supply is an Unmetered Supply.

2.2       Considerations in determining an Unmetered Supply: Each Public
          Electricity Supplier acknowledges that, without prejudice to any other
          factor to which it may choose to have regard in making its
          determination, it would not expect to determine that a supply of
          electricity to a particular inventory of Apparatus is to be treated
          for the purposes of this Agreement as an Unmetered Supply unless it is
          technically impractical to install a Meter or to carry out meter
          readings or the cost of installation of a Meter or of carrying out
          meter readings is wholly disproportionate or the supply of electricity
          in question is both small (in kWh terms) and reasonably predictable.

2.3       Unmetered Supply Certificate: If a Public Electricity Supplier
          determines in accordance with sub-section 2.1 that a supply of
          electricity to a particular inventory of Apparatus qualifies as an
          Unmetered Supply, it shall issue an Unmetered Supply Certificate to
          the Customer taking such supply in relation to such inventory. Such
          Unmetered Supply Certificate shall state whether the Unmetered Supply
          to which it relates is an Equivalent Unmetered Supply or a Profiled
          Unmetered Supply, as agreed between the Public Electricity Supplier
          and the Customer.

<PAGE>


2.4       Inventory: The inventory of Apparatus relative to a particular
          Unmetered Supply shall be agreed between the Public Electricity
          Supplier in whose Authorised Area the Unmetered Supply takes place and
          the Customer taking such supply. The Public Electricity Supplier shall
          ensure that any such inventory includes the means of identifying the
          type and number of items connected and taking supply, the location of
          such items, the wattage and the switch regime. The Public Electricity
          Supplier shall prepare and provide in accordance with the relevant
          Agreed Procedure a summary inventory of Apparatus based on the
          information included in the detailed inventory of Apparatus.

2.5       Equivalent Unmetered Supply: A Public Electricity Supplier shall
          assign a unique Stage 2 Metering System Number to each Unmetered
          Supply Certificate relating to an Equivalent Unmetered Supply in its
          Authorised Area.

2.6       Profiled Unmetered Supply: A Public Electricity Supplier shall assign
          a unique Stage 2 Metering System Number to each Standard Settlement
          Configuration for each Unmetered Supply Certificate relating to a
          Profiled Unmetered Supply in its Authorised Area.

2.7       Equivalent Meters:

          2.7.1     Upon request by a Supplier or the Executive Committee, a
                    Public Electricity Supplier shall notify it in writing of
                    one or more Equivalent Meters to be used in its Authorised
                    Area for the purpose of calculating consumption associated
                    with an Equivalent Unmetered Supply. A Public Electricity
                    Supplier shall be entitled to change its nomination of an
                    Equivalent Meter from time to time provided that it gives at
                    least one year's prior written notice of such change to the
                    Executive Committee. The Executive Committee will, on
                    request by a Supplier, provide details of the Equivalent
                    Meter used or to be used by a Public Electricity Supplier,
                    as notified to the Executive Committee by that Public
                    Electricity Supplier.

          2.7.2     If an Equivalent Meter requires one or more photo electric
                    cell unit arrays to function properly, then the Public
                    Electricity Supplier which nominated the Equivalent Meter
                    shall agree with any relevant Supplier the location(s) of
                    such photo electric cell unit array(s).

2.8       Revised EACs and inventories:

          2.8.1     For each Profiled Unmetered Supply in its Authorised Area,
                    the Public Electricity Supplier shall calculate an Estimated
                    Annual Consumption and shall notify the relevant Supplier or
                    its Supplier Agent of such Estimated Annual Consumption.

          2.8.2     As soon as reasonably practicable after there has been a
                    material change in the inventory of Apparatus to which an
                    Unmetered Supply Certificate relates, the Public Electricity
                    Supplier which issued such Unmetered Supply Certificate
                    shall, in accordance with the relevant Agreed Procedure,
                    provide to the relevant Supplier or its Supplier Agent:-

<PAGE>


                    (a)       a revised summary inventory of Apparatus (in the
                              case of an Equivalent Unmetered Supply); and/or

                    (b)       a new Estimated Annual Consumption (in the case of
                              a Profiled Unmetered Supply).

2.9       Meter administration service: If at the 1998 Operational Date a Public
          Electricity Supplier is providing meter administration services to any
          third party it shall continue to provide meter administration services
          to Suppliers upon request and upon agreement as to the terms and
          conditions thereof, provided that a Public Electricity Supplier shall
          not be obliged to offer to provide such services if after the 1998
          Operational Date it ceases for more than six consecutive months to
          provide meter administration services to third parties.

2.10      Changes to this Section: No amendment or variation of this Section 2
          shall be effective except with the prior agreement of the Public
          Electricity Suppliers (which agreement shall be given by the passing
          of a resolution in a separate class meeting of the Public Electricity
          Suppliers). For the purposes of this Section, the provisions of Part
          III of the Agreement relating to general meetings of Pool Members
          shall apply mutatis mutandis to separate class meetings of Public
          Electricity Suppliers, but so that:-

          (a)       the necessary requirement for notice in writing to be given
                    of any such separate class meeting shall be 5 working days
                    rather than the period in Clause 9.3;

          (b)       Clause 10.9 shall not apply although the Pool Auditor and
                    the Director or its or his duly authorised representative
                    shall have the right to attend and speak (but not vote) at
                    such separate class meetings;

          (c)       such separate class meetings shall be convened by the
                    Secretary upon receipt of a request from a Public
                    Electricity Supplier;

          (d)       the necessary quorum shall be four Public Electricity
                    Suppliers present in person and if no quorum is present
                    within half an hour from the time appointed for the separate
                    class meeting, the separate class meeting shall be adjourned
                    until the following working day; and

          (e)       notice of any such separate class meeting need to be given
                    only to those entitled to attend the same,

          and any resolution put to any such separate class meeting shall, to be
          passed, require a simple majority of the Membership Votes or (as the
          case may be) Weighted Votes of those Pubic Electricity Supplies as
          (being entitled to do so) vote in person or by proxy at such separate
          class meeting.

3.        SUPPLIERS AND UNMETERED SUPPLIES

          Each Supplier shall:-

          3.1       trade Unmetered Supplies on a basis consistent with the
                    terms of the relevant Unmetered Supply Certificate so that
                    Equivalent Unmetered Supplies are treated and traded as such
                    and Profiled Unmetered Supplies are treated and traded as
                    such. A change in the treatment and trading of an Unmetered
                    Supply from an Equivalent Unmetered Supply to a Profiled
                    Unmetered Supply (or vice versa) shall only be made if the
                    relative Unmetered Supply Certificate is withdrawn and
                    cancelled and a new Unmetered Supply Certificate is issued
                    in its place; and

          3.2       ensure that Estimated Annual Consumption or summary
                    inventory of Apparatus associated with an Unmetered Supply
                    Certificate is properly submitted for use in Settlement.

                    Agreement and to co-operate fully with the Pool Auditor and
                    any such other person in any review of such records.

5.6       Charges of Teleswitch Agent: The charges of the Teleswitch Agent shall
          be as set out in its terms of engagement and otherwise as agreed from
          time to time by the Executive Committee. Unless otherwise determined
          by Pool Members in general meeting, the costs, fees, expenses,
          liabilities and losses of, and all other amounts incurred or paid by,
          the Teleswitch Agent shall be dealt with in accordance with Schedule
          31.

5.7       Force Majeure: The terms of engagement of the Teleswitch Agent may
          include provision for certain specific obligations to be suspended for
          a period where the Teleswitch Agent is unable to perform for reasons
          beyond its control provided that the suspension of performance is of
          no greater scope and of no longer duration than is reasonable in the
          circumstances. If any such event occurs, the Executive Committee shall
          if practicable inform the Pool Members and (if the Executive Committee
          considers it appropriate) the Pool Auditor, the Director and (if
          affected by the suspension of performance) any of the other Pool
          Agents.

5.8       Changes to the terms of engagement: The terms of engagement of the
          Teleswitch Agent shall include provision for changes to be made to
          such terms of engagement by agreement between the Executive Committee
          and the Teleswitch Agent and, further, for changes to be made at the
          request of the Executive Committee, subject to the reimbursement of
          the Teleswitch Agent's costs in relation to any such change and to the
          Teleswitch Agent's right to refuse on reasonable grounds to agree to
          any such change.

                              Collection of Charges

                                 PART 1: GENERAL

1.        INTERPRETATION

Interpretation: In this Schedule, unless the context otherwise requires,
references to a particular Part, Section, sub-section or paragraph shall be a
reference to that Part, Section, sub-section or paragraph of this Schedule.

                               PART 2: ERS CHARGES

2.        FUNDING OF 100kW SHORTFALL AND RECOVERY OF CHARGES

2.1       Allocation of 100kW Shortfall Amount: In respect of each month from
          and including 1st April, 1998 that part (if any) of the 100kW
          Shortfall Amount due or expected to fall due in that month (as
          determined by the Executive Committee) shall be funded by Pool Members
          according to their respective Contributory Shares (on the basis of the
          then most recently calculated current Contributory Shares).

2.2       Collection and payment of 100kW Shortfall Amount funding:

          2.2.1     The Executive Committee shall collect from Pool Members the
                    amounts which they are obliged to pay in accordance with
                    sub-section 2.1 towards the 100kW Shortfall Amount monthly
                    in advance in accordance with procedures agreed from time to
                    time by the Executive Committee and Pool Members shall pay
                    their proportionate share of such amounts in accordance with
                    such procedures.

          2.2.2     If any Pool Member fails to pay an amount properly due in
                    connection with its funding of the 100kW Shortfall Amount
                    under this Section within 15 days of the due date for such
                    payment (such Pool Member being a "Non-paying Contributor")
                    each Pool Member (other than the Non-paying Contributor)
                    shall be severally liable for that Pool Member's
                    Contributory Share (calculated on the basis that the Points
                    allocated to the Non-paying Contributor are disregarded and
                    on the basis of the then most recently calculated current
                    Contributory Shares) and the Executive Committee shall
                    accordingly be entitled to recover the due proportion of
                    that amount from each Pool Member (other than the Non-paying
                    Contributor). In that event, the Executive Committee shall
                    advise each Pool Member of the amount payable by invoice
                    despatched to each Pool Member and each Pool Member shall
                    pay the amount advised in the relevant invoice within 15
                    days after the invoice date.

          2.2.3     A Non-paying Contributor shall indemnify and keep
                    indemnified each Pool Member on demand against all sums
                    properly paid by such Pool Member pursuant to this
                    sub-section 2.2.

<PAGE>


          2.2.4     Each Pool Member shall give notice to the Executive
                    Committee before instituting any action or proceedings to
                    enforce payments due to it pursuant to sub-section 2.2. Upon
                    receipt of any notice under this paragraph 2.2.4, the
                    Executive Committee will as soon as practicable notify all
                    Pool Members. The provisions of sub-section 24.4 of Schedule
                    11 shall apply mutatis mutandis in respect of any payment
                    due from a Non-paying Contributor pursuant to this
                    sub-section 2.2.

          2.2.5     The amounts so collected together with any amount
                    transferred pursuant to sub-section 3.6 of Part G of the
                    Appendix to Schedule 4 (and any interest accrued on any such
                    amounts as referred to in this paragraph) shall be applied
                    by the Executive Committee in or towards meeting the 100kW
                    Shortfall Amount and, pending such application, may be
                    deposited in an interest-bearing account under the control
                    of the Executive Committee.

2.3       Determination of 100kW Shortfall Charge: The 100kW Shortfall Charge
          for an Accounting Period shall be determined by the Executive
          Committee as the amount payable by each Supplier in that Accounting
          Period in respect of each Chargeable 100kW Premises.

2.4       Determination of quarterly charge: The charge payable by each Supplier
          pursuant to this Section in respect of each Quarter shall be
          calculated in accordance with the following formula:-

                  100kW Shortfall Charge x N100P
                  ----------------------
                             4


          where N100P is the total number of Chargeable 100kW Premises relating
          to that Supplier as at the beginning of the relevant Quarter,
          determined in accordance with sub-section 2.5.

2.5       Determination of Chargeable 100kW Premises: For the purposes of
          sub-section 2.4:-

          2.5.1     the number of "Chargeable 100kW Premises" relating to a
                    Supplier as at the beginning of each Quarter shall be
                    determined by the Executive Committee (the Executive
                    Committee being entitled, in the absence of any information
                    to the contrary, to rely on the information relating to the
                    last Quarter for which it has information) by reference to
                    (i) the number of Metering Systems (if any) registered in
                    ERS in respect of which the Supplier is the Registrant at
                    the start of that Quarter (as notified to the Executive
                    Committee by the Settlement System Administrator) and (ii)
                    the number of 100kW Premises in relation to which one or
                    more Metering Systems (if any) are effectively registered
                    against that Supplier in a PES Registration Service as at
                    the start of that Quarter (as notified to the Executive
                    Committee by the relevant Supplier, but subject to
                    adjustment as provided in paragraph 2.5.2); and

          2.5.2     the number of 100kW Premises with Metering Systems
                    registered in a PES Registration Service as notified by each
                    Supplier shall be adjusted pro rata by the Executive
                    Committee so that the total number of Metering Systems
                    registered in ERS for all Suppliers, when added to the total
                    number of 100kW Premises not registered in ERS

<PAGE>


                    for all Suppliers taken into account by the Executive
                    Committee as Chargeable 100kW Premises, is equal to the
                    total number of Metering Systems registered in ERS on the
                    first day of the month in which the first GSP Group
                    Migration Date occurs.

2.6       Notification to Suppliers: The Executive Committee shall, not less
          than fifteen Business Days before the end of each Quarter, beginning
          with the Quarter ending on 30th June, 1998, notify each Supplier of
          the amount (if any) due from it pursuant to sub-section 2.4.

2.7       Payment by Suppliers: Each Supplier shall pay, no later than the last
          Business Day of the relevant Quarter, the amount for that Quarter
          notified to it by the Executive Committee in accordance with
          sub-section 2.6.

2.8       Adjustments for leaving and new Suppliers: Any Supplier which is a
          Supplier for part only of any Quarter shall pay charges pursuant to
          sub-sections 2.4 and 2.7 on an interim basis of such amount as the
          Executive Committee estimates to be reasonable for such Quarter.
          Adjustments to charges on all Suppliers as a result of existing
          Suppliers leaving or new Suppliers joining will be made in such manner
          as the Executive Committee shall determine, whereupon the Suppliers
          and/or former Suppliers shall be required to pay such additional
          amount or be entitled to such reimbursement as may be determined by
          the Executive Committee by an adjustment to charges in respect of the
          then current Quarter.

2.9       Provisions relating to payments generally: Any payment to be made by a
          Pool Member or (as the case may be) a Supplier under this Section
          shall be made to the Executive Committee (or as otherwise directed by
          the Executive Committee), for distribution in accordance with
          sub-section 2.12, in sterling in cleared funds in full without set off
          or counterclaim, withholding or deduction of any kind whatsoever but
          without prejudice to any other remedy. All charges under this Section
          are exclusive of United Kingdom Value Added Tax which shall be added
          to such charges, if applicable.

2.10      No withholding: In the event of any dispute regarding charges in any
          Quarter, no Pool Member or (as the case may be) Supplier may withhold
          payment of any invoiced amount under this Section but may refer such
          dispute to arbitration in accordance with Clause 83.

2.11      Interest on non-payment: If any amount due under this Section is not
          received on the due date, the Pool Member or, as the case may be, the
          Supplier required to pay such amount shall pay interest (for
          distribution in accordance with sub-section 2.12) to the Executive
          Committee (or as otherwise directed by the Executive Committee) on
          such amount from and including the date of default to the date of
          actual payment (as well after as before judgment) at the Default
          Interest Rate from time to time during such period of default.

2.12      Allocation of amounts recovered: The amounts recovered from Suppliers
          pursuant to this Section shall be available for distribution amongst
          Pool Members according to their contributions to the funding of the
          100kW Shortfall Amount in accordance with sub-sections 2.1 and 2.2.
          Amounts received in respect of a Quarter shall be so distributed on
          the first Business Day of the next following Quarter and any amounts
          received late shall be distributed on the same basis as soon as
          reasonably practicable following their receipt. Each Pool Member

<PAGE>


          shall accordingly be entitled to receive its due proportion of amounts
          received from Suppliers pursuant to this Section on the basis that:-

          2.12.1    each Pool Member who has contributed to the 100kW Shortfall
                    Amount pursuant to sub-sections 2.1 and 2.2 shall be
                    entitled to be reimbursed (out of the amounts so recovered
                    from Suppliers) in respect of the sum of:-

                    (a)       the amount so contributed by that Pool Member; and

                    (b)       an amount equal to that Pool Member's 100kW
                              Shortfall Financing Costs in relation to the
                              amount so contributed by it;

          2.12.2    any amount so received from a Supplier shall be applied by
                    the Executive Committee in or towards the amount payable by
                    that Supplier in respect of the longest outstanding invoice;
                    and

          2.12.3    any amounts paid to Pool Members by way of reimbursement of
                    their funding of the 100kW Shortfall Amount shall be applied
                    by the Executive Committee to the Pool Member or Pool
                    Members with the longest outstanding unreimbursed funding
                    payments made pursuant to sub-sections 2.1 and 2.2.

2.13      Delegation by Executive Committee: The Executive Committee may arrange
          for EPFAL or some other person nominated by it from time to time to
          carry out all or any of its functions pursuant to sub-sections 2.1 to
          2.12 (save where the Executive Committee is required to make a
          determination or an estimate pursuant to any of sub-sections 2.1, 2.3,
          2.5 and 2.8), in which case the applicable references to the Executive
          Committee in those sub-sections are to be read as references to EPFAL
          or such other person so long as such delegation continues. The
          Executive Committee shall promptly give notice to all Pool Members of
          any such delegation.

2.14      Aggregate recovery: The Executive Committee shall use its reasonable
          endeavours to ensure that the aggregate of all 100kW Shortfall Charges
          payable pursuant to this Section is such as to allow the recovery, by
          the end of the 100kW Shortfall Recovery Period, of the 100kW Shortfall
          Amount funded pursuant to sub-sections 2.1 and 2.2, with due allowance
          being made for the aggregate of 100kW Shortfall Financing Costs.

2.15      Overriding provision: The provisions of this Part shall have effect
          notwithstanding the provisions of Clause 34A.

3.        VARIABLE ERS CHARGES

3.1       Determination of Variable ERS Charge: Subject to sub-section 3.4, the
          Variable ERS Charge for an Accounting Period shall be determined, for
          each Accounting Period beginning with that starting on 1st April,
          1998, by the Executive Committee as the amount payable for that
          Accounting Period by each Supplier in respect of each Metering System
          registered in ERS for which that Supplier is the Registrant. The
          Variable ERS Charge in respect of an Accounting Period beginning after
          1st April, 1998 shall, failing any determination by the Executive

<PAGE>


          Committee in respect of that Accounting Period, be the same as that
          most recently determined (or (as the case may be) re-determined
          pursuant to sub-section 3.5) in respect of a prior Accounting Period.

3.2       Calculation of variable ERS charge payable: The charge payable by each
          Supplier in respect of each month in an Accounting Period shall be
          calculated in accordance with the following formula:-

                  Variable ERS Charge x NMS
                  -------------------
                           12


          where NMS is the number of Metering Systems registered in ERS for
          which the Supplier is the Registrant at the beginning of the relevant
          month.

3.3       Determination of Metering Systems: For the purposes of sub-section
          3.2, the number of Metering Systems attributable to a Supplier as at
          the beginning of a month shall be as determined by the Settlement
          System Administrator (the Settlement System Administrator being
          entitled, in the absence of any notification to the contrary, to rely
          on the most recent information in its possession).

3.4       Treatment of deficit or surplus variable ERS charges: If in respect of
          any Accounting Period the aggregate of all Variable ERS Charges
          payable pursuant to sub-section 3.2 and received by the Settlement
          System Administrator is less than or (as the case may be) more than
          the Total Variable ERS Charges for such Accounting Period, the deficit
          or (as the case may be) the surplus shall be carried forward to the
          immediately succeeding Accounting Period and shall be taken into
          account in the calculation of the Variable ERS Charge therefor.

3.5       Executive Committee responsibility: The Executive Committee will use
          its reasonable endeavours to ensure that the aggregate of all Variable
          ERS Charges payable pursuant to sub-section 3.2 and received by the
          Settlement System Administrator meets the Total Variable ERS Charges
          specified for that Accounting Period. The Executive Committee may
          accordingly from time to time determine that the Variable ERS Charge
          in respect of an Accounting Period should be adjusted, whereupon
          Suppliers shall be required to pay such additional amounts or be
          entitled to such reimbursement as may be determined by the Executive
          Committee by an adjustment to charges in respect of any month in that
          or any later Accounting Period.

4.        FIXED ERS CHARGES

4.1       Determination of Fixed ERS Charge: Subject to the provisions of this
          Section, the Fixed ERS Charge for an Accounting Period shall be
          determined, for each Accounting Period beginning with that starting on
          1st April, 1998, by the Executive Committee as the amount payable for
          that Accounting Period by each Supplier in respect of each Chargeable
          100kW Premises. The Fixed ERS Charge in respect of an Accounting
          Period beginning after 1st April, 1998 shall, failing any
          determination by the Executive Committee in respect of that Accounting
          Period, be the same as that most recently determined (or (as the case
          may be) re-determined pursuant to sub-section 4.4) in respect of a
          prior Accounting Period.

<PAGE>


4.2       Calculation of fixed ERS charge payable: The charge payable by each
          Supplier in respect of each month in an Accounting Period shall be
          calculated in accordance with the following formula:-

                  Fixed ERS Charge x N100P
                  ----------------
                         12

          where N100P is the total number of Chargeable 100kW Premises relating
          to that Supplier as at the beginning of the Quarter in which that
          month falls, determined in accordance with sub-section 2.5.

4.3       Treatment of deficit or surplus fixed ERS charges: If in respect of
          any Accounting Period the aggregate of all Fixed ERS Charges payable
          pursuant to sub-section 4.2 and received by the Settlement System
          Administrator is less than or (as the case may be) more than the Total
          Fixed ERS Charges for such Accounting Period, the deficit or (as the
          case may be) the surplus shall be carried forward to the immediately
          succeeding Accounting Period and shall be included in the calculation
          of the Fixed ERS Charge therefor.

4.4       Executive Committee responsibility: The Executive Committee will use
          its reasonable endeavours to ensure that the aggregate of all Fixed
          ERS Charges payable pursuant to sub-section 4.2 and received by the
          Settlement System Administrator meets the Total Fixed ERS Charges
          specified for that Accounting Period. The Executive Committee may
          accordingly from time to time determine that the Fixed ERS Charge in
          respect of an Accounting Period should be adjusted, whereupon
          Suppliers shall be required to pay such additional amounts or be
          entitled to such reimbursement as may be determined by the Executive
          Committee by an adjustment to charges in respect of any month in that
          or any later Accounting Period.

5.2       Determination of compliance and amounts payable: The Performance
          Assurance Board shall determine whether a Supplier has failed to
          comply with any of the Serials and the associated charges payable, in
          each case as soon as is reasonably practicable following receipt by
          the Performance Assurance Board of the Routine Performance Monitoring
          Reports pursuant to Serial 10.

5.3       Basis of determination: The Performance Assurance Board shall make its
          determination on the basis of the information provided to it in the
          Routine Performance Monitoring Reports adjusted where appropriate to
          reflect the circumstances which applied at the time when the
          calculations would have been made if the Routine Performance
          Monitoring Reports had been provided within the time period specified
          in Serial 10.

5.4       Adjustment of calculations following application of the Supplier's
          Monthly Cap: When making its determination pursuant to sub-section 5.2
          of whether a Supplier has failed to comply with any of the Serials and
          the associated charges payable by the Supplier, the Performance
          Assurance Board shall compare the Supplier's Net Liability for the
          relevant month (calculated as SNL below) with the Supplier's Monthly
          Cap. If the Supplier's Net Liability exceeds the Supplier's Monthly
          Cap then the total charges payable by the Supplier in respect of the
          relevant month shall be calculated according to the following formula
          (instead of by general application of the Menu of Supplier Charges):-

          Supplier's charges = STGC x [SC/SNL]

          where:-

          STGC      is the total charges which would be payable by the Supplier
                    for the relevant month under this Part 3 in respect of the
                    relevant GSP Group before the application of this
                    sub-section;

          SC        is the Supplier's Monthly Cap for the relevant month
                    (calculated pursuant to sub-section 16.2 of the Menu of
                    Supplier Charges); and

          SNL       is the total charges which would be payable by the Supplier
                    for the relevant month under this Part 3 in respect of the
                    relevant GSP Group before the application of this
                    sub-section, less any share of those charges payable by the
                    Supplier which would otherwise be receivable by the Supplier
                    pursuant to sub-section 5.12 before the application of this
                    sub-section.

5.5       Notification by Performance Assurance Board: As soon as practicable
          following a determination pursuant to sub-section 5.2, the Performance
          Assurance Board shall notify each Supplier of the amount (if any) due
          from it pursuant to this Section in respect of any particular month in
          respect of failures to comply with any of the Serials. Any
          notification by the Performance Assurance Board pursuant to this
          sub-section shall specify the GSP Group in relation to which the
          relevant amount is payable by a Supplier (where relevant).

5.6       Payment by Suppliers: Each Supplier shall pay the amount notified to
          it by the Performance Assurance Board in accordance with sub-section
          5.5 within 15 days after the invoice date. Any such payment shall be
          made to the Performance Assurance Board (for distribution in
          accordance with sub-sections 5.12 and 5.13) in sterling in cleared
          funds in full without set-off or counterclaim, withholding or
          deduction of any kind whatsoever but without prejudice to any other
          remedy. All charges under this Part 3 are exclusive of United Kingdom
          Value Added Tax which shall be added to such charges, if applicable.

5.7       No withholding: In the event of any dispute regarding charges in
          respect of any month, no Supplier may withhold payment of any invoiced
          amount.

<PAGE>


5.8       Interest on late payment: If any amount due under this Part 3 is not
          received on the due date, or if the Performance Assurance Board has to
          calculate any amounts due under this Part 3 following the late receipt
          of a Routine Performance Monitoring Report, the Supplier required to
          pay such amount shall pay interest to the Performance Assurance Board
          on such amount from and including the date of default, or deemed due
          date (calculated as if the relevant report had been submitted on
          time), to the date of actual payment (before as well as after
          judgment) at the Default Interest Rate from time to time during such
          period of default.

5.9       Interest on payments resulting from delays in the Performance
          Assurance Reporting and Monitoring System: If the Performance
          Assurance Board is unable to calculate any amounts due under this Part
          3 as a result of delays in the Performance Assurance Reporting and
          Monitoring System being operational, then the Supplier required to pay
          any such amounts shall pay interest to the Performance Assurance Board
          from and including the deemed due date for payment, calculated in
          accordance with sub-section 19.2 of the Menu of Supplier Charges, to
          the date of payment (before as well as after judgment) at the Base
          Rate from time to time during such period.

5.10      Application of payments: Any amount received by the Performance
          Assurance Board pursuant to this Part 3 shall be applied by the
          Performance Assurance Board (unless otherwise specified by the paying
          Supplier) in or towards payment of amounts payable by the Supplier in
          respect of the longest outstanding invoice and (where there is a
          shortfall in payment by a Supplier of any amounts specified in a
          single invoice in respect of different GSP Groups) according to the
          proportion which the individual amounts payable pursuant to the
          invoice bear to the total amount payable under that invoice.

5.11      Accounting by the Performance Assurance Board: Any amounts paid by a
          Supplier pursuant to this Part 3 shall be accounted for separately by
          the Performance Assurance Board by reference to the GSP Group in
          respect of which the relevant amounts have been collected or
          appropriated. The Performance Assurance Board shall not be obliged to
          segregate any amounts received pursuant to this Part 3 into separate
          funds.

5.12      Recovery by Suppliers: Each qualifying Supplier shall be entitled to
          receive its due proportion of amounts recoverable pursuant to this
          Part 3 and available for distribution in respect of a GSP Group. For
          this purpose:-

          5.12.1    a "qualifying Supplier" is a Supplier who has at any time
                    during the relevant month supplied any customers in the
                    relevant GSP Group who have Non Half Hourly Metering
                    Systems;

          5.12.2    the due proportion relating to a qualifying Supplier is the
                    amount (as near as may be) calculated by the Performance
                    Assurance Board as that Supplier's share of the total
                    quantity of energy (after adjustment for Line Loss Factors)
                    attributable to Non Half Hourly Metering Systems taken by
                    all Suppliers in the GSP Group during the relevant month
                    pursuant to this Agreement;

<PAGE>


          5.12.3    the amount available for distribution in relation to a GSP
                    Group in respect of a particular month is 90 per cent. of
                    the total amount from time to time paid or due and payable
                    from Suppliers pursuant to this Part 3 in relation to the
                    relevant GSP Group in respect of that month, whether or not
                    then paid; and

          5.12.4    the information as to total quantity of energy referred to
                    in paragraph 5.12.2 shall be as provided by the Initial
                    Settlement and Reconciliation Agent based on the latest
                    available run of Stage 2 Settlement as at the time when the
                    relevant calculation falls to be made.

5.13      Recovery by Pool Members: Each qualifying Pool Member shall be
          entitled to receive a share of amounts recoverable pursuant to this
          Part 3 and available for distribution in respect of Pool Members in
          the proportion to which a Pool Member's Contributory Share bears to
          the Contributory Shares of all Pool Members applicable in respect of
          the relevant month. For this purpose:-

          5.13.1    a "qualifying Pool Member" is a Pool Member who was at any
                    time during the relevant month a Pool Member; and

          5.13.2    the amount recoverable pursuant to this Part 3 and available
                    for distribution to qualifying Pool Members in respect of a
                    particular month is 10 per cent. of the total amount from
                    time to time paid or due and payable from Suppliers pursuant
                    to this Part 3 in relation to the relevant GSP Group in
                    respect of that month, whether or not then paid.

5.14      Payments to Suppliers and Pool Members: The Performance Assurance
          Board shall, by no later than the end of each month, calculate the
          amount (if any) payable to each qualifying Supplier and qualifying
          Pool Member pursuant to sub-section 5.12 and sub-section 5.13 in
          respect of the relevant preceding month (or months) to which a
          Supplier's Routine Performance Monitoring Report relates and any
          earlier months. The Performance Assurance Board shall, by no later
          than the end of each month, notify each qualifying Supplier and
          qualifying Pool Member of the amounts (if any) so recoverable by them
          and shall account to each qualifying Supplier and qualifying Pool
          Member on a monthly basis out of the funds received in respect of any
          particular GSP Group for the amounts so recoverable. The Performance
          Assurance Board shall in no circumstances be obliged to account to a
          qualifying Supplier or qualifying Pool Member in an amount exceeding
          the available funds collected pursuant to this Part 3. Any amounts so
          paid by the Performance Assurance Board to a qualifying Supplier or
          qualifying Pool Member shall be deemed to be inclusive of any United
          Kingdom Value Added Tax, if applicable.

5.15      Rights of Suppliers and Pool Members entitled to a recovery: The
          provisions of this Part 3 shall give rise to rights and obligations as
          between Suppliers within the same GSP Group and as between qualifying
          Pool Members generally and the relevant Supplier. The procedures for
          collection and payment of amounts by the Performance Assurance Board
          shall accordingly be without prejudice to the rights of any qualifying
          Supplier or qualifying Pool Member to enforce its claim (to the extent
          not paid or otherwise satisfied) against any Supplier who fails to
          make payment on the due date.

5.16      Delegation by Performance Assurance Board: The Performance Assurance
          Board may arrange for EPFAL or some other person nominated by it from
          time to time to carry out all or any of its functions pursuant to
          sub-sections 5.1 to 5.15 (save where the Performance Assurance Board
          is required to make a determination pursuant to any of sub-sections
          5.2 and 5.3 and paragraph 5.12.2), in which case references to the
          Performance Assurance Board in those sub-sections are to be read as
          references to EPFAL or such other person so long as such delegation
          continues.

6.8       Non payment provision:

          6.8.1     Without prejudice to sub-section 6.7, if any Pool Member
                    fails to pay an amount properly due under this Section
                    within 15 days of the due date for such payment (such Pool
                    Member being a "Non-paying Pool Member") each Pool Member
                    (other than the Non-paying Pool Member) shall be severally
                    liable for its Contributory Share (calculated on the basis
                    that the Points allocated to the Non-paying Pool Member are
                    disregarded and on the basis of the then most recently
                    calculated current Contributory Shares) and EPFAL shall
                    accordingly be entitled to recover the due proportion of
                    that amount from each Pool Member (other than the Non-paying
                    Pool Member). In that event, the Executive Committee shall
                    advise each Pool Member and each Pool Member shall pay the
                    amount advised in the relevant invoice within 15 days after
                    the invoice date.

          6.8.2     A Non-paying Pool Member shall indemnify and keep
                    indemnified each Pool Member on demand against all sums
                    properly paid by such Pool Member pursuant to this
                    sub-section 6.8.

          6.8.3     Each Pool Member shall give notice to the Executive
                    Committee before instituting any action or proceedings to
                    enforce payments due to it pursuant to this Section. Upon
                    receipt of any notice under this paragraph 6.8.3, the
                    Executive Committee will as soon as practicable notify all
                    Pool Members. The provisions of sub-section 24.4 of Schedule
                    11 shall apply mutatis mutandis in respect of any payment
                    due from a Non-paying Pool Member pursuant to this Section.

6.9       Delegation by Executive Committee:

          6.9.1     The Executive Committee may from time to time nominate some
                    other person to carry out all or any of the functions
                    specified to be carried out by EPFAL pursuant to this
                    Section or determine to carry out such functions itself, in
                    which case the applicable references to EPFAL are to be read
                    as references to the person so nominated or (as the case may
                    be) the Executive Committee for so long as such nomination
                    or (as the case may be) determination continues.

          6.9.2     The Executive Committee shall promptly give notice to all
                    Pool Members of any such nomination, determination or
                    re-nomination.

          6.9.3     EPFAL shall be entitled (subject to any contrary agreement
                    with the Executive Committee) to cease to carry on all such
                    functions if at any time it ceases to be the Pool Funds
                    Administrator. In that event, the Executive Committee shall
                    itself carry out such functions or nominate some other
                    person to do so, in each case with effect from the date of
                    termination of EPFAL's role, in which event the provisions
                    of paragraph 6.9.1 shall apply.

          of this Section.

7.2       Allocation of Stage 2 Operational Costs: The Stage 2 Operational Costs
          in respect of any Accounting Period shall be allocated as to half
          amongst all Generators and as to half amongst all Suppliers.

7.3       Payment and Collection:

          7.3.1     The Executive Committee shall collect from Pool Members the
                    amounts which they are obliged to pay towards Stage 2
                    Operational Costs pursuant to this Section and Pool Members
                    shall pay their share of such costs in accordance with
                    procedures approved from time to time by the Executive
                    Committee.

          7.3.2     Unless otherwise determined by the Executive Committee and
                    subject to the other provisions of this Section and Section
                    8, payments in respect of such costs shall be made monthly
                    in advance on the basis of estimates prepared by the
                    Executive Committee of the Stage 2 Operational Costs which
                    will or may fall due in each month.

7.4       Allocation of Stage 2 costs to Generators: Generators shall contribute
          towards the Stage 2 Operational Costs attributable to Generators in
          the proportions which their respective Contributory Shares bear to the
          aggregate Contributory Shares of Generators determined as X for the
          purposes of Section 5 of Schedule 13.

7.5       Allocation of Stage 2 costs to Suppliers:

          7.5.1     The "Suppliers' Half Hourly Charge" for an Accounting Period
                    shall be determined by the Executive Committee as the amount
                    payable in that Accounting Period in respect of each
                    Chargeable Metering System. The Executive Committee may from
                    time to time adjust the Suppliers' Half Hourly Charge in
                    respect of an Accounting Period, either before or after the
                    expiry of that Accounting Period. The Suppliers' Half Hourly
                    Charge in respect of an Accounting Period beginning after
                    1st April, 1998 shall, failing any determination by the
                    Executive Committee in respect of that Accounting Period, be
                    the same as that most recently determined in respect of a
                    prior Accounting Period.

                              where:-

                              OCS is the aggregate Stage 2 Operational Costs
                              attributable to Suppliers in respect of that
                              Accounting Period in accordance with sub-section
                              7.2;

                              TS2HHC is the total of the charges payable by all
                              Suppliers in respect of that month in accordance
                              with paragraph 7.5.2(i);

                              SNHH is the aggregate quantity of energy
                              (expressed in MWh) relating to Non Half Hourly
                              Metering Systems for which that Supplier is
                              responsible for all Settlement Periods in the
                              Calculation Period relating to that month; and

                              TNHH is the aggregate quantity of energy
                              (expressed in MWh) relating to Non Half Hourly

                              Month; and

                    (ii)      the volumes of energy shall be as determined, for
                              all Settlement Periods in the Calculation Period
                              relating to a month, from the final run of Stage 1
                              Settlement and the latest available run of Stage 2
                              Settlement as at the close of business on the
                              Business Day immediately preceding the relevant
                              Calculation Date.

7.6       Non payment provision:

          7.6.1     If any Pool Member fails to pay an amount properly due under
                    this Section within 15 days of the due date for such payment
                    (such Pool Member being a "Non-paying Pool Member") each
                    Pool Member (other than the Non-paying Pool Member) shall be
                    severally liable for its Contributory Share (calculated on
                    the basis that the Points allocated to the Non-paying Pool
                    Member are disregarded and on the basis of the then most
                    recently calculated current Contributory Shares) of the
                    amount payable by such Non-paying Pool Member pursuant to
                    sub-section 7.4 or (as the case may be) sub-section 7.5 and
                    the Executive Committee shall accordingly be entitled to
                    recover the due proportion of that amount from each Pool
                    Member (other than the Non-paying Pool Member). In that
                    event, the Executive Committee shall advise each Pool Member
                    of the amount payable by invoice despatched to each Pool
                    Member and each Pool Member shall pay the amount advised in
                    the relevant invoice within 15 days after the invoice date.

          7.6.2     A Non-paying Pool Member shall indemnify and keep

                    properly paid by such Pool Member pursuant to this
                    sub-section 7.6.

          7.6.3     Each Pool Member shall give notice to the Executive
                    Committee before instituting any action or proceedings to
                    enforce payments due to it pursuant to this Section. Upon
                    receipt of any notice under this paragraph 7.6.3, the
                    Executive Committee will as soon as practicable notify all
                    Pool Members. The provisions of sub-section 24.4 of

<PAGE>


                    Schedule 11 shall apply mutatis mutandis in respect of any
                    payment due from a Non-paying Pool Member pursuant to this
                    Section.

7.7       Transitional provisions: The Executive Committee may, in its
          discretion, determine the respective charges to be payable by
          Suppliers pursuant to sub-section 7.5 according to such transitional
          arrangements as it considers appropriate from time to time having
          regard to the availability of information concerning Half Hourly
          Metering Systems or (as the case may be) Non Half Hourly Metering
          Systems and volumes of energy attributable to particular Suppliers.
          Without prejudice to the foregoing, the Executive Committee shall
          establish reasonable transitional arrangements for the period from the
          date when the provisions of this Section come into effect until the
          information referred to is available in respect of all GSP Groups and
          Pool Members shall pay the charges established in accordance with
          those arrangements.

7.8       Delegation by Executive Committee: The Executive Committee may arrange
          for EPFAL or some other person nominated by it from time to time to
          carry out all or any of its functions pursuant to this Section (save
          where the Executive Committee is required to make a determination or
          estimate pursuant to any of paragraphs 7.3.2, 7.3.3, 7.5.1, 7.5.3 and
          sub-section 7.7), in which case the applicable references to the
          Executive Committee in this Section are to be read as references to
          the EPFAL or such other person so long as such delegation continues.
          The Executive Committee shall promptly give notice to all Pool Members
          of any such delegation.

8.        GENERAL PROVISIONS

8.1       Allocation of costs: The Executive Committee shall determine from time
          to time whether any particular costs or category of costs fall to be

          in respect of any Accounting Period or other period.

8.2       Provisions relating to payments generally: Any payment to be made by a
          Pool Member (whether a Generator or Supplier) under this Part shall be
          made to the relevant payee (or as otherwise directed by the Executive
          Committee) in sterling in cleared funds in full without set off or
          counterclaim, withholding or deduction of any kind whatsoever but
          without prejudice to any other remedy. All charges and payments under
          this Part are exclusive of United Kingdom Value Added Tax which shall
          be added to such charges or payments, if applicable.

8.3       No withholding: In the event of any dispute regarding charges or
          payments under this Part in any month or period, no Pool Member may
          withhold payment of any invoiced amount but may refer such dispute to
          arbitration in accordance with Clause 83.

8.4       Interest on non-payment: If any amount due under this Part is not
          received on the due date, the Pool Member required to pay such amount

8.5       Adjustments: The Executive Committee shall from time to time determine
          what (if any) adjustments are necessary as a result of:-

          8.5.1     any recalculation of Contributory Shares or (as the case may
                    be) volumes of energy on any Calculation Date after the
                    initial Calculation Date relating to a month;

          8.5.2     any recalculation of Pool Administration Costs referable to
                    a month pursuant to sub-section 8.6;

                    a month pursuant to sub-section 8.6;

          8.5.4     any recalculation of Stage 2 Operational Costs referable to
                    a month by virtue of a change in the Calculation Period
                    relating to a month;

          8.5.5     existing Pool Members leaving or new Pool Members joining;
                    and

          8.5.6     any change of capacity in which a Party participates as a
                    Pool Member.

          Notwithstanding the foregoing provisions, no adjustment shall fall to
          be made in respect of charges payable by Suppliers as a result of
          revised information in relation to quantities of energy attributable
          to particular Suppliers becoming available to the Executive Committee
          on account of a Reconciliation Run.

8.6       Recalculation of costs: On each Calculation Date during an Accounting
          Period and on the Final Calculation Date in respect of an Accounting
          Period, the Executive Committee shall:-

          8.6.1     re-calculate the Pool Administration Costs referable to each
                    wholly or partially elapsed month in that Accounting Period
                    and in the Following Month (if in that Accounting Period)
                    such that the amount of those costs treated as referable to
                    each such month is equal; and

          8.6.2     re-calculate the Stage 2 Operational Costs referable to each
                    wholly or partially elapsed month in that Accounting Period
                    and in the Following Month (if in that Accounting Period)
                    such that the amount of those costs treated as referable to
                    each such month is equal.

8.7       Consequences of adjustments:

          8.7.1     Whenever the Executive Committee determines that an
                    adjustment is necessary pursuant to sub-section 8.5, the
                    Pool Members and/or former Pool Members concerned shall be
                    required to pay such additional amounts or be entitled to
                    such reimbursement as may be determined by the Executive
                    Committee by an adjustment to charges in respect of a
                    preceding month or the Following Month.

<PAGE>


          8.7.2     No adjustment shall fall to be made unless the information
                    which gives rise to the adjustment is available as at close
                    of business on the Business Day immediately before a
                    Calculation Date.

          8.7.3     No reimbursement shall be made to a leaving Pool Member in
                    respect of any month until the necessary adjustments (if
                    any) have been made to take into account, following the end
                    of the Accounting Period in which that Party is to cease to
                    be a Pool Member, the final run of Stage 1 Settlement and
                    the Stage 1 Initial Settlement Run in respect of all
                    Settlement Periods during which that Party traded as a Pool
                    Member.

8.8       Invoice amounts: The Executive Committee shall not be required to
          issue any invoice, nor to pay an amount by way of reimbursement (nor
          issue any credit note in respect of any such reimbursement), to a Pool
          Member if the aggregate amount otherwise payable by, or to be
          reimbursed by, that Pool Member pursuant to Sections 6 and 7 and
          sub-section 8.5 is less than the minimum from time to time determined
          by the Executive Committee provided that if in respect of an
          Accounting Period such aggregate amount is less than such minimum
          amount, the Executive Committee shall issue an invoice in respect of
          such aggregate amount (which the Pool Member shall be required to pay)
          immediately after the Final Calculation Date for such Accounting
          Period. Where the minimum applies, a Pool Member shall remain liable
          for any amounts payable by it but shall not be required to make any
          payment until such time as the amount in question is included in an
          invoice. Sub-section 8.4 shall be construed accordingly.

                    PART 5: MISCELLANEOUS SETTLEMENT CHARGES

9.1       Charges relating to disputes: The Executive Committee shall be
          entitled to require that a fee or other charge (not
          exceeding(pound)500 per dispute or such other sum as the Pool Members
          in general meeting may from time to time approve) be levied on and
          paid by a Party in respect of any dispute concerning Settlement or its
          operation (including with respect to data) referred by such Party for
          determination to the Executive Committee or any sub-committee thereof.
          Such fee or other charge shall be levied, paid and collected in such
          manner and at such time as the Executive Committee shall direct and
          the relevant Party hereby undertakes to pay any such fee or other
          charge so levied. Any such fee or other charge shall at the option of
          the Executive Committee (i) be refunded in whole or in part to the
          Party which paid the same, or (ii) be applied against the
          administration costs of whatsoever nature of the Executive Committee
          or the relevant sub-committee.

          8.1       Annual General Meeting: Poolit's annual general meeting at

9.        FINANCE FOR POOLIT

9.1       Poolit's financing needs: The Poolit Shareholders acknowledge and
          agree with the other Poolit Shareholders and Poolit that Poolit will
          from time to time require finance in order to fund its projected cash
          requirements and to meet its liabilities.

9.2       Limits on financing: Poolit agrees that it shall not incur costs in
          respect of any of its Financial Years of an amount greater than the
          "Poolit Maximum Aggregate Shareholder Contribution" in respect of that
          Financial Year. The Poolit Maximum Aggregate Shareholder Contribution
          in respect of a Financial Year of Poolit shall be that amount which
          those Poolit Shareholders who together as Pool Members have not less
          than 84 per cent. of the Weighted Votes of all Pool Members shall
          agree in writing no later than twenty working days before the start of
          that Financial Year. The Poolit Company Secretary shall determine and
          shall give notice to all Poolit Directors and Poolit Shareholders of
          his determination whether a Poolit Maximum Aggregate Shareholder
          Contribution has been so agreed in respect of a Financial Year of
          Poolit and, if so agreed, the amount of that Poolit Maximum Aggregate
          Shareholder Contribution. If no such agreement is reached in respect
          of a Financial Year then, until such time as such agreement is
          reached, the Poolit Maximum Aggregate Shareholder Contribution in
          respect of such Financial Year shall be(pound)1 million.

9.3       Poolit Shareholders' contribution: The Poolit Shareholders shall be
          liable to contribute towards the financing requirements of Poolit in
          accordance with their respective Contributory Shares and shall make
          payment of their proportionate share (together with Value Added Tax
          thereon, if applicable) to Poolit or to such other person as Poolit
          may from time to time direct within fifteen days after receipt of an
          invoice or other statement therefor issued by Poolit.

9.4       Non-paying Poolit Shareholders: If any Poolit Shareholder fails to pay
          an amount due to Poolit under this Schedule within fifteen days after
          the due date for such payment (such Poolit Shareholder being a
          "Non-paying Poolit Shareholder"), each Poolit Shareholder (other than
          the Non-paying Poolit Shareholder) shall be severally liable for its
          Contributory Share (calculated on the basis that the Points allocated
          to the Non-paying Poolit Shareholder are disregarded) of that amount
          and Poolit shall accordingly be entitled to recover the due proportion
          of that amount from each Poolit Shareholder (other than the Non-paying
          Poolit Shareholder). In that event, Poolit shall advise each Poolit
          Shareholder of the amount payable by invoice or statement despatched
          to each Poolit Shareholder and each Poolit Shareholder shall pay
          Poolit (or such other person as Poolit may from time to time direct)
          the amount advised in the relevant invoice or statement within fifteen
          days after receipt.

9.5       Non-paying Poolit Shareholder's indemnity: A Non-paying Poolit
          Shareholder shall indemnify each Poolit Shareholder on demand against
          all sums properly paid by such Poolit Shareholder pursuant to
          sub-section 9.4 and all costs and expenses reasonably incurred by each
          Poolit Shareholder in recovering such sums. Any payment by a
          Non-paying Poolit Shareholder pursuant to such indemnity shall be made
          without any deduction and free and clear of and without any deduction
          for or on account of any taxes, except to the extent that the
          Non-paying Poolit Shareholder is required by law to make payment
          subject to any taxes. If any tax or amounts in respect of tax must be
          deducted or any other deductions must be made from any

<PAGE>


          amounts payable or paid by a Non-paying Poolit Shareholder pursuant to
          such indemnity, the Non-paying Poolit Shareholder shall pay such
          additional amounts as may be necessary to ensure that the relevant
          Poolit Shareholder receives a net amount equal to the full amount
          which it would have received had payment not been made subject to tax.

9.6       Third party finance: If Poolit requires finance in addition to that
          provided by the Poolit Shareholders pursuant to sub-sections 9.3 and
          9.4, it shall endeavour to obtain such finance from a third party
          lender on the best terms which could reasonably be expected to be
          obtained in the open market.

9.7       Poolit Shareholder guarantees: If any indemnity, guarantee or other
          assurance against loss is given by a Poolit Shareholder for any
          obligation or liability of Poolit, at the request of Poolit all the
          other Poolit Shareholders shall indemnify such Poolit Shareholder in
          respect of any liability arising out of such indemnity, guarantee or
          other assurance against loss in the proportions which the respective
          Contributory Shares of all the Poolit Shareholders bear one to the
          other at the time of request for indemnification.

10.       TRANSFER OF POOLIT SHARES

          following provisions of this Section 10 no Poolit Shareholder shall:-

          10.1.1    pledge, mortgage (whether by way of fixed or floating
                    charge) or otherwise encumber its legal or beneficial
                    interest in its Poolit Shares; or

          10.1.2    sell, transfer or otherwise dispose of any of such Poolit
                    Shares (or any legal or beneficial interest therein); or

          10.1.3    enter into any agreement in respect of the votes attached to
                    Poolit Shares; or

          10.1.4    agree, whether or not subject to any condition precedent or
                    subsequent, to do any of the foregoing.

10.2      Intra-group transfers: A Poolit Shareholder may transfer its Poolit

          a Pool Member at the same time as such Poolit Shareholder ceases to be
          a Pool Member.

10.3      Retiring Poolit Shareholders: If in relation to any of the Poolit
          Shareholders (the "Retiring Poolit Shareholder"):-

          10.3.1    the Retiring Poolit Shareholder ceases to be a Pool Member
                    for any reason; or

          10.3.2    the Retiring Poolit Shareholder fails to remedy any material
                    breach on its part of this Schedule within 21 days after the
                    service of any written notice by a majority in number of the
                    other Poolit Shareholders complaining of such breach; or

<PAGE>


          10.3.3    any of the events set out in Clause 66.3.6 or 66.3.7 shall
                    occur in relation to the Retiring Poolit Shareholder,

          other Poolit Shareholder, the Retiring Poolit Shareholder shall
          transfer at par to a nominee for all the Poolit Shareholders (other
          than the Retiring Poolit Shareholder) selected by the Poolit Directors
          all of the Poolit Shares held by the Retiring Poolit Shareholder. All
          costs and expenses of such transfer shall be for the account of the
          Retiring Poolit Shareholder.

          refuse to transfer any Poolit Shares in accordance with its
          obligations under sub-section 10.3 the Poolit Directors may authorise
          Poolit to execute and deliver a transfer from the Retiring Poolit
          Shareholder to a nominee on behalf of the Retiring Poolit Shareholder.
          Poolit may accept the consideration for the transfer and hold it on
          trust for the Retiring Poolit Shareholder, which acceptance shall be a
          good discharge to the nominee and may set off such amount against the
          costs and expenses of the transfer. The Poolit Directors shall cause
          the transferee to be registered as the holder of such Poolit Shares
          and, following the registration of the transfer, the validity of the
          proceedings shall not be questioned by any person.

                    for the winding up of Poolit,

          provided, however, that this Schedule shall cease to have effect as
          regards any Poolit Shareholder who ceases to hold any Poolit Shares
          (save that any accrued rights and obligations as at the date of
          cessation shall not be thereby extinguished).

12.       POOLIT SHAREHOLDERS GENERALLY

          The Poolit Shareholders shall procure that, save for any nominee
          referred to in sub-section 10.3:-

          12.1      no person other than a Pool Member shall acquire shares in
                    Poolit (whether by transfer or allotment) and that no Pool
                    Member shall be a Poolit Shareholder unless and until it

<PAGE>


                    has agreed to be bound by this Schedule in the capacity of a

          Shareholder a non-exclusive, royalty-free licence to use the Licensed
          IPR on substantially the terms and conditions which those Poolit
          Shareholders who together as Pool Members have not less than 84 per

14.       CONFLICT WITH THE ARTICLES

          In the event of any ambiguity or discrepancy between the provisions of

          reasonably requested from time to time in order to carry out, evidence
          and confirm their or its rights under, and the intended purpose of,
          this Schedule.

          meeting of the holders of all of the shares, of the holders of not
          less than 95 per cent. in nominal value of all the issued shares. All
          the provisions of these articles as to general meetings of the company
          shall, with any necessary modifications, apply to any such separate
          general meeting, but so that the necessary quorum shall be two persons
          holding or representing by proxy not less than one-third in nominal
          value of the issued shares (but so that at any adjourned meeting one
          holder present in person or by proxy (whatever the number of shares
          held by him) shall be a quorum) and that any holder of a share present
          in person or by proxy may demand a poll.

6.2       Subject to the provisions of the Act, the voting rights and rights
          relating to the return of capital to members for the time being

          in nominal value of all the issued shares or with the sanction of an
          extraordinary resolution passed at a separate general meeting of the
          holders of all of the shares. All the provisions of these articles as
          to general meetings of the company shall, with any necessary
          modifications, apply to any such separate general meeting, but so that
          the necessary quorum shall be two persons holding or representing by
          proxy not less than one-third in nominal value of the issued shares
          (but so that at any adjourned meeting one holder present in person or
          by proxy (whatever the number of shares held by him) shall be a
          quorum) and that any holder of shares present in person or by proxy
          may demand a poll.

          who may (subject to Article 4) offer, allot, grant options over or
          otherwise dispose of them to such persons at such times and for such

          unconditionally authorised to exercise all powers of the company to
          allot relevant securities. The maximum nominal amount of relevant
          securities that may be allotted under this authority shall be the
          nominal amount of the unissued share capital at the date of
          incorporation of the company or such other amount as may from time to
          time be authorised by the company in general meeting. The authority
          conferred on the directors by this article shall remain in force for a
          period of five years from the date of incorporation of the company but
          may be revoked, varied or renewed from time to time by the company in
          general meeting in accordance with the Act.

                    interest in its shares; or

          10.2.2    sell, transfer or otherwise dispose of any of such shares
                    (or any legal or beneficial interest therein); or

          10.2.3    enter into any agreement in respect of the votes attached to
                    shares; or

          Shareholder"):-

          10.4.1    the Retiring Poolit Shareholder ceases to be a Pool Member

                    breach on its part of Schedule 33 to the Pooling and
                    Settlement Agreement within 21 days after the service of any
                    written notice by a majority (in number and value) of the
                    other members complaining of such breach; or

<PAGE>


          10.4.3    any of the events set out in Clause 66.3.6 or 66.3.7 of the
                    Pooling and Settlement Agreement shall occur in relation to
                    the Retiring Poolit Shareholder,

          then, upon written notice to the Retiring Poolit Shareholder by any
          other member, the Retiring Poolit Shareholder shall transfer at par to
          a person selected by the directors all of the shares held by the
          Retiring Poolit Shareholder. All costs and expenses of such transfer
          shall be for the account of the Retiring Poolit Shareholder.

10.5      If a Retiring Poolit Shareholder shall fail or refuse to transfer any
          shares in accordance with its obligations under Article 10.4 the
          directors may authorise the company to execute and deliver a transfer
          from the Retiring Poolit Shareholder to a nominee on behalf of the
          Retiring Poolit Shareholder. The company may accept the consideration
          for the transfer and hold it on trust for the Retiring Poolit
          Shareholder, which acceptance shall be a good discharge to the nominee
          and may set off such amount against the costs and expenses of the
          transfer. The directors of the company shall cause the transferee to
          be registered as the holder of such shares and, following the
          registration of the transfer, the validity of the proceedings shall
          not be questioned by any person.

          shall do so his vote shall be counted and he shall be taken into

          prejudice to any indemnity to which the person concerned may otherwise
          be entitled, every director or other officer of the company shall be
          indemnified, and if the board so determines an auditor may be
          indemnified, out of the assets of the company against any liability
          incurred by him as a director or other officer of the company, or as
          auditor, in defending any proceedings (whether civil or criminal) in
          which judgment is given in his favour or he is acquitted or in
          connection with any application under the Act in which relief is
          granted to him by the court. For the purposes of this article no
          person appointed or employed by the company as an auditor is an
          officer of the company.

          Poolserco Business Plans are prepared and submitted to the Board for
          approval no later than three months before the end of each of

          by the Board and by those Shareholders who together as Pool Members
          have not less than 84 per cent. of the Weighted Votes of all Pool
          Members, it shall become definitive for that period. If a draft
          Poolserco Business Plan is not approved prior to the commencement of
          the relevant Financial Year, the most recently approved Poolserco
          Business Plan shall be adopted as the Poolserco Business Plan for such
          year until such time as a later draft Poolserco Business Plan for such
          Financial Year is approved.

7.3       Poolserco obligations: Poolserco shall comply with the most recently
          approved Poolserco Business Plan and, in particular, agrees that,
          without the prior consent of those Shareholders who together as Pool
          Members have not less than 84 per cent. of the Weighted Votes of all
          Pool Members, it shall not incur costs in respect of the period to
          which a Poolserco Business Plan relates of an amount greater than the
          Maximum Aggregate Shareholder Contribution which is identified as such
          in such Poolserco Business Plan.

8.        ACCOUNTS

8.1       Annual Accounts: At the end of each of Poolserco's Financial Years, or
          as soon as reasonably practicable thereafter, Poolserco shall procure
          that an account shall be taken of all the assets and liabilities of
          Poolserco and of all dealings and transactions of Poolserco during
          such Financial Year and that the Board shall prepare a report and
          accounts in accordance with the Companies Act 1985 to be audited
          within three months after the end of each Financial Year.

          Poolserco to instruct the auditors of Poolserco to conduct a review in
          respect of the financial affairs of Poolserco. The cost of such review
          shall be borne by the Shareholder requesting such review, unless such
          review is approved by the majority of Directors in which case it shall
          be borne by Poolserco. If any such review is requested, Poolserco
          shall procure that Poolserco's auditors are given all reasonable
          assistance to complete the review within a reasonable period of time.

9.        DISTRIBUTION POLICY

          The Shareholders shall take such action as may be necessary to procure
          that:-

9.1       Annual General Meeting: Poolserco's annual general meeting at which
          audited accounts in respect of its preceding Financial Year are laid
          before the Shareholders is held not later than the date falling six
          months after the end of that Financial Year;

9.2       Auditors' Report: Poolserco's auditors shall at the expense of
          Poolserco be instructed to report as to the amount of the profits
          available for distribution by Poolserco for each accounting reference
          period at the same time as they sign their report on Poolserco's
          audited accounts for the accounting reference period in question; and

9.3       Distribution of Profits: Subject to the appropriation of such
          reasonable and proper reserves for working capital or otherwise as the
          Board may consider appropriate, Poolserco distributes to and among the
          Shareholders within 30 days of approval of the audited accounts 100
          per cent. of its profits available for distribution in each year. For
          this purpose no part of any surplus arising in such Financial Year by
          reason of Shareholders' contributions pursuant to sub-section 10.2
          being found to be in excess of Poolserco's requirements for that
          Financial Year shall be available for distribution so that the whole
          of any such surplus shall be dealt with in accordance with sub-section
          10.2.

10.       FINANCE FOR POOLSERCO

10.1      Poolserco's financing needs: The Shareholders acknowledge and agree
          with the other Shareholders and Poolserco that Poolserco will from
          time to time require finance in order to fund its projected cash
          requirements and to meet its liabilities.

10.2      Shareholders' contribution: The Shareholders shall be liable to
          contribute in accordance with their respective Contributory Shares
          towards the financing requirements of Poolserco in respect of any
          Financial Year of Poolserco up to the Maximum Aggregate Shareholder
          Contribution which is identified as such in the Poolserco Business
          Plan for such Financial Year or such greater amount as is agreed by
          Shareholders under the terms of sub-section 7.3. Poolserco shall
          procure that any amounts received by it which are surplus to its
          requirements in any Financial Year shall be carried forward to the
          next following Financial Year of Poolserco and reduce the amount of
          the Maximum Aggregate Shareholder Contribution for that next following
          Financial Year of Poolserco, so that a corresponding reduction shall
          be made to the contribution that any Shareholder would, in the absence
          of such surplus, have been liable to make to Poolserco for the next
          following Financial Year of Poolserco. Shareholders shall make payment
          of their proportionate share (together with Value Added Tax thereon,
          if applicable) to Poolserco or to such other person as Poolserco may
          from time to time direct within fifteen days after receipt of an
          invoice or other statement therefor issued by Poolserco.

10.3      Non-paying Shareholders: If any Shareholder fails to pay an amount due
          to Poolserco under this Schedule within fifteen days after the due
          date for such payment (such Shareholder being a "Non-paying
          Shareholder"), each Shareholder (other than the Non-paying
          Shareholder) shall be

<PAGE>


          severally liable for its Contributory Share (calculated on the basis
          that the Points allocated to the Non-paying Shareholder are
          disregarded) of that amount and Poolserco shall accordingly be
          entitled to recover the due proportion of that amount from each
          Shareholder (other than the Non-paying Shareholder). In that event,
          Poolserco shall advise each Shareholder of the amount payable by
          invoice or statement despatched to each Shareholder and each
          Shareholder shall pay Poolserco (or such other person as Poolserco may
          from time to time direct) the amount advised in the relevant invoice
          or statement within fifteen days after receipt.

10.4      Non-paying Shareholder's indemnity: A Non-paying Shareholder shall
          indemnify each Shareholder on demand against all sums properly paid by
          such Shareholder pursuant to sub-section 10.3 and all costs and
          expenses reasonably incurred by each Shareholder in recovering such
          sums. Any payment by a Non-paying Shareholder pursuant to such
          indemnity shall be made without any deduction and free and clear of
          and without any deduction for or on account of any taxes, except to
          the extent that the Non-paying Shareholder is required by law to make
          payment subject to any taxes. If any tax or amounts in respect of tax
          must be deducted, or any other deductions must be made, from any
          amounts payable or paid by a Non-paying Shareholder pursuant to such
          indemnity, the Non-paying Shareholder shall pay such additional
          amounts as may be necessary to ensure that the relevant Shareholder
          receives a net amount equal to the full amount which it would have
          received had payment not been made subject to tax.

10.5      Shareholder guarantees: If any indemnity, guarantee or other assurance
          against loss is given by a Shareholder for any obligation or liability
          of Poolserco at the request of Poolserco, all the other Shareholders
          shall indemnify such Shareholder in respect of any liability arising
          out of such indemnity, guarantee or other assurance against loss in
          the proportions which the respective Contributory Shares of all the
          Shareholders bear one to the other at the time of request for
          indemnification.

11.       TRANSFER OF SHARES

11.1      Restriction on transfer: Otherwise than in accordance with the
          following provisions of this Section 11 no Shareholder shall:-

          11.1.1    pledge, mortgage (whether by way of fixed or floating
                    charge) or otherwise encumber its legal or beneficial
                    interest in its Shares; or

          11.1.2    sell, transfer or otherwise dispose of any of such Shares
                    (or any legal or beneficial interest therein); or

          11.1.3    enter into any agreement in respect of the votes attached to
                    Shares; or

          11.1.4    agree, whether or not subject to any condition precedent or
                    subsequent, to do any of the foregoing.

<PAGE>


11.2      Intra-group transfers: A Shareholder may transfer its Shares to its
          Affiliate in circumstances where such Affiliate becomes a Pool Member
          at the same time as such Shareholder ceases to be a Pool Member.

11.3      Retiring Shareholders: If in relation to any of the Shareholders (the
          "Retiring Shareholder"):-

          11.3.1    the Retiring Shareholder ceases to be a Pool Member for any
                    reason; or

          11.3.2    the Retiring Shareholder fails to remedy any material breach
                    on its part of this Schedule within 21 days after the
                    service of any written notice by a majority in number of the
                    other Shareholders complaining of such breach; or

          11.3.3    any of the events set out in Clause 66.3.6 or 66.3.7 shall
                    occur in relation to the Retiring Shareholder,

          then, upon written notice to the Retiring Shareholder by any other
          Shareholder, the Retiring Shareholder shall transfer at par to a
          nominee for all the Shareholders (other than the Retiring Shareholder)
          selected by the Directors all of the Shares held by the Retiring
          Shareholder. All costs and expenses of such transfer shall be for the
          account of the Retiring Shareholder.

11.4      Enforced transfer: If a Retiring Shareholder shall fail or refuse to
          transfer any Shares in accordance with its obligations under
          sub-section 11.3 the Directors may authorise Poolserco to execute and
          deliver a transfer from the Retiring Shareholder to a nominee on
          behalf of the Retiring Shareholder. Poolserco may accept the
          consideration for the transfer and hold it on trust for the Retiring
          Shareholder, which acceptance shall be a good discharge to the nominee
          and may set off such amount against the costs and expenses of the
          transfer. The Directors shall cause the transferee to be registered as
          the holder of such Shares and, following the registration of the
          transfer, the validity of the proceedings shall not be questioned by
          any person.

11.5      Nominee's holding: The nominee referred to in sub-section 11.3 shall
          hold Shares transferred to it on the terms set out in that sub-section
          until such time as it is directed by the Directors to transfer them
          (or some of them) to one or more Pool Members.

12.       DURATION AND TERMINATION

This Schedule shall continue in full force and effect until the first to occur
of the following events:-

12.1      the termination of this Agreement pursuant to Clause 67.4;

12.2      all the Shareholders agree in writing to terminate the arrangements
          set out in this Schedule; and

<PAGE>


12.3      an effective resolution is passed or a binding order is made for the
          winding up of Poolserco,

provided, however, that this Schedule shall cease to have effect as regards any
Shareholder who ceases to hold any Shares (save that any accrued rights and
obligations as at the date of cessation shall not be thereby extinguished).

13.       SHAREHOLDERS GENERALLY

The Shareholders shall procure that, save for any nominee referred to in
sub-section 11.3:-

13.1      no person other than a Pool Member shall acquire shares in Poolserco
          (whether by transfer or allotment) and that no Pool Member shall be a
          Shareholder unless and until it has agreed to be bound by this
          Schedule in the capacity of a Shareholder (which it shall be taken to
          have done by being a signatory to this Agreement); and

13.2      no person shall at any point hold more than one Share.

14.       INTELLECTUAL PROPERTY

          If and to the extent that any Shareholder discloses any of its
          Intellectual Property to Poolserco for use in connection with the
          Business, unless it is unable to do so it shall grant, and shall be
          deemed to have granted from the date of such disclosure, licences of
          such Intellectual Property to Poolserco for use in connection with the
          Business and for no other purpose whatsoever. Any such licence shall
          be irrevocable, non-exclusive, perpetual and royalty-free. Such
          licences shall not be capable of assignment or sub-licence by
          Poolserco.

15.       CONFLICT WITH THE ARTICLES

          In the event of any ambiguity or discrepancy between the provisions of
          this Schedule and the Articles, then it is the intention of the
          Shareholders that the provisions of this Schedule (for so long as they
          remain in force) shall prevail and accordingly the Shareholders shall
          exercise all voting and other rights and powers available to them so
          as to give effect to the provisions of this Schedule.

16.       FURTHER ASSURANCE

          Each Shareholder shall co-operate with the other Shareholders and with
          Poolserco and shall execute and deliver to the other Shareholders or
          Poolserco (as the case may be) such other instruments and documents
          and take such other actions as may be reasonably requested from time
          to time in order to carry out, evidence and confirm their or its
          rights under, and the intended purpose of, this Schedule.

          meeting of the holders of all of the shares, of the holders of not

          the provisions of these articles as to general meetings of the company

          general meeting, but so that the necessary quorum shall be two persons
          holding or representing by proxy not less than one-third in nominal
          value of the issued shares (but so that at any adjourned meeting one

          in nominal value of all the issued shares or with the sanction of an
          extraordinary resolution passed at a separate general meeting of the

          (but so that at any adjourned meeting one holder present in person or
          by proxy (whatever the number of shares held by him) shall be a
          quorum) and that any holder of shares present in person or by proxy

          who may (subject to Article 4) offer, allot, grant options over or
          otherwise dispose of them to such persons at such times and for such
          consideration and upon such terms and conditions as they may

          unconditionally authorised to exercise all powers of the company to
          allot relevant securities. The maximum nominal amount of relevant
          securities that may be allotted under this authority shall be the
          nominal amount of the unissued share capital at the date of
          incorporation of the company or such other amount as may from time to
          time be authorised by the company in general meeting. The authority
          conferred on the directors by this article shall remain in force for a
          period of five years from the date of incorporation of the company but
          may be revoked varied or renewed from time to time by the company in

                    interest in its shares; or

                    (or any legal or beneficial interest therein); or

          10.2.3    enter into any agreement in respect of the votes attached to
                    shares; or

          where such Affiliate becomes a Pool Member at the same time as such
          member ceases to be a Pool Member.

          10.4.1    the Retiring Shareholder ceases to be a Pool Member for any
                    reason; or

          10.4.2    the Retiring Shareholder fails to remedy any material breach
                    on its part of Schedule 34 to the Pooling and Settlement
                    Agreement within 21 days after the service of any written
                    notice by a majority (in number and value) of the other
                    members complaining of such breach; or

          10.4.3    any of the events set out in Clause 66.3.6 or 66.3.7 of the
                    Pooling and Settlement Agreement shall occur in relation to
                    the Retiring Shareholder,

          then upon written notice to the Retiring Shareholder by any other
          member, the Retiring Shareholder shall transfer at par to a person
          selected by the directors all of the shares held by the Retiring
          Shareholder. All costs and expenses of such transfer shall be for the
          account of the Retiring Shareholder.

10.5      If a Retiring Shareholder shall fail or refuse to transfer any shares
          in accordance with its obligations under Article 10.4 the directors
          may authorise the company to execute and deliver a transfer from the
          Retiring Shareholder to a nominee on behalf of the Retiring
          Shareholder. The company may accept the consideration for the transfer
          and hold it on trust for the Retiring Shareholder, which acceptance
          shall be a good discharge to the nominee and may set off such amount
          against the costs and expenses of the transfer. The directors of the
          company shall cause the transferee to be registered as the holder of
          such shares and, following the registration of the transfer, the
          validity of the proceedings shall not be questioned by any person.

          several documents in like form each executed by one or more of the

          company shall declare the nature of his interest at a meeting of the
          directors in accordance with the Act. Subject where applicable to such
          disclosure, a director shall be entitled to vote in respect of any
          contract or proposed contract in which he is interested and if he
          shall do so his vote shall be counted and he shall be taken into
          account in ascertaining whether a quorum is present. Regulations 94
          and 95 of Table A shall not apply.

27.       Official Seal

          The company may exercise all the powers conferred by the Act with
          regard to having any official seal and such powers shall be vested in
          the directors. Subject to the provisions of the Act, any instrument to
          which an official seal is affixed shall be signed by such persons, if
          any, as the directors may from time to time determine.

          to a number provided by the member for this purpose, or by leaving it
          at his registered address addressed to the member, or by any other
          means authorised in writing by the member concerned. In the case of
          joint holders of a share, service or delivery of any notice or other

          Any notice or other document, if sent by the company by post, shall be
          deemed to have been served or delivered twenty four hours after
          posting and, in proving such service or delivery, it shall be
          sufficient to prove that the notice or document was properly
          addressed, stamped and

<PAGE>


          put in the post. Any notice or other document left by the company at a
          registered address otherwise than by post, or sent by fax or telex or
          other instantaneous means of transmission, shall be deemed to have
          been served or delivered when it was so left or sent. Regulation 115
          of Table A shall not apply.

30.       Indemnity of Officers

          Subject to the provisions of the Act, the company may indemnify any
          director or other officer against any liability and may purchase and
          maintain for any director or other officer or auditor insurance
          against any liability. Subject to those provisions, but without
          prejudice to any indemnity to which the person concerned may otherwise
          be entitled, every director or other officer of the company shall be
          indemnified, and if the board so determines an auditor may be
          indemnified, out of the assets of the company against any liability
          incurred by him as a director or other officer of the company, or as
          auditor, in defending any proceedings (whether civil or criminal) in
          which judgment is given in his favour or he is acquitted or in
          connection with any application under the Act in which relief is
          granted to him by the court. For the purposes of this article no
          person appointed or employed by the company as an auditor is an
          officer of the company.

2.        REVIEW OF ELECTRICITY TRADING ARRANGEMENTS

2.1       Changes to Electricity Trading Arrangements: The Parties acknowledge
          that reviews of the electricity trading arrangements may result in
          changes to the existing electricity trading arrangements and such
          changes may require amendments to the provisions of the SAV Licences
          and the Type 1 Goal Licence including the scope of use provisions.

2.2       Amendment of SAV Licences: Subject to sub-section 2.4, if at any time
          during, or upon the finalisation of, the review of the electricity
          trading arrangements referred to in sub-section 2.1, the existing
          electricity trading arrangements are changed as part of that review
          and the position under the SAV Licences is thereby affected, and NGC
          will continue to use Goal to assist in the function of central
          scheduling of generation or to use Goal (in whole or in part) as part
          of the interface between generators and NGC and SAV Licensees wish to
          continue to utilise Goal, then, upon written notice from either of
          them, NGC and each SAV Licensee shall negotiate in good faith
          amendments to the SAV Licences subject to prior discussions with the
          Executive Committee (including amendments to the scope of use of the
          relevant SAV Licences and provided that any proposed increase in
          licence fees shall be limited to such increase in fees which are
          required by a head licensor) so as to enable the SAV Licensees to
          model the output of the central scheduler and to ensure that data is
          compliant with the interface. The agreement of NGC and the SAV
          Licensees to such amendments shall not be unreasonably withheld or
          delayed. In the event of a failure to agree any such amendment within
          90 days (or such longer

<PAGE>


          period as shall be agreed by NGC and the relevant SAV Licensee) after
          receipt by NGC or the SAV Licensee, as the case may be, of the written
          notice initiating the negotiation, either NGC or the SAV Licensee may
          (at any time thereafter) refer the matter to arbitration in accordance
          with Clause 83. Pending determination of that reference, the relevant
          licence shall continue in effect.

2.3       Amendment of Type 1 Goal Licence: Subject to sub-section 2.4, if at
          any time during, or upon the finalisation of, the review of the
          electricity trading arrangements referred to in sub-section 2.1, the
          existing electricity trading arrangements are changed as part of that
          review and the position under the Type 1 Goal Licence is thereby
          affected and the Settlement System Administrator wishes to continue to
          utilise Goal, then, upon written notice from any of them, NGC, the
          Executive Committee and the Settlement System Administrator shall
          negotiate in good faith amendments to the Type 1 Goal Licence
          (including amendments to the scope of use of the Type 1 Goal Licence
          and provided that any proposed increase in licence fees shall be
          limited to such increase in fees which are required by a head
          licensor) so as to enable the Settlement System Administrator to
          produce the Unconstrained Schedule and to ensure that data is
          compliant with the interface. The agreement of NGC, the Executive
          Committee and the Settlement System Administrator to such amendments
          shall not be unreasonably withheld or delayed. In the event of a
          failure to agree any such amendment within 90 days (or such longer
          period as shall be agreed by NGC, the Executive Committee and the
          Settlement System Administrator) after receipt by NGC or the
          Settlement System Administrator, as the case may be, of the written
          notice initiating the negotiation, either NGC or the Settlement System
          Administrator may (at any time thereafter) refer the matter to
          arbitration in accordance with Clause 83. Pending determination of
          that reference, the relevant licence shall continue in effect.

2.4       Head Licensor Consent: To the extent that the amendments agreed
          pursuant to sub-sections 2.2 and 2.3 require the consent of any head
          licensor of NGC, then NGC shall, subject to the payment of its
          reasonable costs and expenses in connection therewith, use its
          reasonable endeavours to obtain the consent of such head licensors to
          any such amendment.

2.5       Future Licences: If NGC is required to grant new SAV Licences or a
          Type 1 Goal Licence after the implementation of any changes following
          the review of the electricity trading arrangements referred to in
          sub-section 2.1, such licences shall reflect the revisions to the
          relevant licence agreed pursuant to this Section 2 notwithstanding
          that such licence terms may differ from the Type 1 Goal Licence or the
          principles set out in Appendix 2, as the case may be.

3.        TYPE 1 GOAL LICENCE

3.1       Grant of Type 1 Goal Licence: On receipt of a request in writing from
          the Executive Committee or the Settlement System Administrator (in
          this Section 3, each a "Licence Applicant") NGC shall, subject to
          sub-section 3.6, grant a Type 1 Goal Licence to the Settlement System
          Administrator no later than the date specified in the Licence
          Applicant's request as the date on which it requires the Type 1 Goal

                    Settlement System Administrator shall enter into a Type 1
                    Support and Maintenance Agreement. NGC shall promptly (and
                    in any event within 30 days after receipt of the request)
                    deliver a draft form of Type 1 Support and Maintenance

                    Maintenance Agreement, the Executive Committee, NGC or the
                    Settlement System Administrator may refer the dispute to
                    arbitration in accordance with Clause 83 provided that, in
                    which such case, the arbitrator appointed pursuant to Clause
                    83 shall be required to take account of the principles set
                    out in Appendix 4 in determining such dispute.

                    conjunction with Settlement Goal for the purposes of the
                    Energy Uplift and Transmission Losses Scheme 2. The
                    operation and running of Old Goal for these purposes shall
                    be limited to and take effect for all Schedule Days prior to
                    and including the Goal Effective Date as if the relevant
                    provisions of Supplemental Agreement 25 in so far as it
                    affects Old Goal (other than the provisions of this
                    sub-section 3.5) had not come into effect.

          3.5.2     For the period of 3 months only following the Goal Effective
                    Date NGC shall continue to make available to the Settlement
                    System Administrator, at the direction of the Executive
                    Committee, Old Goal for the purposes of resolving any
                    dispute between Parties in respect of the financial
                    obligations owed by Parties to each other which are based
                    upon the use of Old Goal prior to the Goal Effective Date.

                    the financial obligations owed by Parties to each other
                    which is based upon the use or operation of Old Goal and
                    which would require for its resolution Old Goal shall be
                    resolved by the Executive Committee provided that where any
                    such dispute is not resolved by the Executive Committee to
                    the satisfaction of the Parties any Party to the dispute may
                    refer the dispute to arbitration in accordance with Clause
                    83.

          and the SAV Licensee shall enter into the SAV Licence forthwith upon
          agreement by NGC, the SAV Licensee and, if different, the requesting
          Party as to its terms. If no such agreement is reached within 60 days
          after receipt of the draft form of SAV Licence, NGC or the requesting
          Party may refer the dispute to arbitration in accordance with Clause
          83 provided that, in which such case the arbitrator appointed pursuant
          to Clause 83 shall be required to take account of the relevant
          principles relating to the SAV Licence in question set out in Appendix
          2 in determining such dispute.

          agreement with that Party in relation to the payment of NGC's
          reasonable costs and expenses incurred in connection therewith, NGC
          will use reasonable endeavours to obtain the consent of its
          head-licensors to the grant of a licence by NGC substantially similar
          to the SAV Licences but for uses of Goal:-

          4.2.1     that do not fall within the scope of use permitted by the
                    SAV Licences; and

          4.2.2     by or for the benefit of a Party solely in connection with
                    its own business needs in connection with the Pool.

          Upon receipt of the consent of its head licensors NGC and the
          requesting Party shall enter into good faith discussions with a view
          to agreeing the terms of the licence. NGC and the requesting Party, or
          person specified in the request, as the case may be, shall enter into
          such licence forthwith upon agreement by NGC and the requesting Party
          as to its terms. If no such agreement is reached within 60 days after
          the request of the Party, NGC or the requesting Party may refer the
          dispute to

<PAGE>


          arbitration in accordance with Clause 83 provided that, in which such
          case, the arbitrator appointed pursuant to Clause 83 shall be required
          to take account of the principles set out in Appendix 2 (save for
          those principles relating to scope of use) and the scope of use
          requirement set out in paragraph 4.2.2 in determining such dispute.

4.3       Executive Committee Nominee Licence: At the request of the Executive
          Committee NGC shall enter into good faith discussions with the
          Executive Committee with a view to agreeing the terms of a licence
          (such terms being based on the Type 1 Goal Licence with such
          amendments as NGC may require) to be granted by NGC to a person
          nominated by the Executive Committee to hold, inter alia, the
          intellectual property rights of Pool Members collectively which have
          been developed under the 1998 Programme. Notwithstanding the foregoing
          NGC shall be under no obligation to grant such licence. Failure to
          grant such a licence shall not be considered a dispute and the
          provisions of Clause 83 shall not apply.

4.4       Termination of NGC's Obligation: The obligation on NGC to grant SAV
          Licences in accordance with sub-sections 4.1 and 4.2 shall terminate
          on 1st January, 2010. Notwithstanding the foregoing, any SAV Licence

                              any such problem is in NGC's reasonable opinion
                              the immediate implementation of an Emergency Fix
                              to Generation Schedule Goal or is in the
                              Settlement System Administrator's reasonable

                              be, provided that each of them shall give the
                              Executive Committee as much notice of such
                              Emergency Fix, together with the reasons for, and
                              the timing and description of, such Emergency Fix,
                              as is practicable in the circumstances.

                    (b)       If it is not practicable to inform the Executive
                              Committee in advance of any Emergency Fix which
                              has been implemented, NGC or the Settlement System
                              Administrator, as the case may be, shall inform
                              the Executive Committee as soon as is practicable

                              working days of the date on which a Settlement
                              Goal Enhancement Proposal is approved by Pool
                              Members in general meeting (such Party being

                    (b)       Subject to NGC's and any Appealing Party's
                              approval of a Settlement Goal Enhancement Proposal

                              incorporating the provisions of the Settlement
                              Goal Enhancement Proposal and unless otherwise
                              agreed, based on service levels and other

                              that apply to the Settlement System Administrator
                              under the Service Lines that apply under Schedule
                              4 provided that such service lines and other
                              commercial terms are reasonable in all of the
                              circumstances existing at the relevant time. In
                              the event of any dispute or difference of any kind
                              arising between NGC and Pool Members as to the
                              terms of the Enhancement Agreement either NGC or
                              Pool Members may refer such dispute to arbitration
                              in accordance with Clause 83.

                    (c)       Following the execution and coming into force of
                              the Enhancement Agreement, the Enhancement
                              Agreement shall regulate the relationship between
                              NGC and Pool Members in relation to the relevant
                              Settlement Goal Enhancement which NGC shall
                              undertake. Without prejudice to the provisions of
                              the Goal Escrow Agreement, and for the avoidance
                              of doubt, the Executive Committee, the Settlement
                              System Administrator and Parties shall have no
                              rights to undertake any Settlement Goal
                              Enhancement themselves.

6.6       Goal Consistency Management: Where NGC makes any changes to Settlement
          Goal or Generation Schedule Goal under this Schedule or any
          maintenance and support arrangements then NGC shall, either before or
          after making such change, propose a corresponding and consequential
          change to Generation Schedule Goal or Settlement Goal, as the case may
          be, and the Datum Document in the form of a Settlement Goal
          Enhancement or Generation Schedule Goal Enhancement, as the case may
          be, provided that NGC shall not be obliged to make any such
          corresponding and consequential change to Generation Schedule Goal,
          Settlement Goal or the Datum Document if such a change would:

          6.6.1     detract from the security or quality of supply or safe
                    operation of the NGC Transmission System; or

          6.6.2     give rise to a breach of its obligations under the NGC
                    Transmission Licence or the Act; or

          6.6.3     have material adverse effect on NGC in respect of the
                    Transmission Services Activity (as defined in the NGC
                    Transmission Licence) where such effect has not been agreed
                    by NGC.

          If NGC objects to any such change, the matter shall be referred to the
          Director.

6.7       Information to Director: Unless otherwise notified by the Director,
          the Executive Committee shall keep the Director fully advised of any
          Settlement Goal Enhancements, Generation Schedule Goal Enhancements or
          Emergency Fixes and of any proposed Settlement Goal Enhancements,
          Generation Schedule Goal Enhancements or Emergency Fixes of which it
          is aware.

          2.1.1     to make and use an unlimited number of copies of the
                    Licensed Program at a main Location;

          2.1.2     to make and use an unlimited number of copies of the
                    Licensed Program at other Locations, solely for the purposes
                    of providing back-up support in the event of any failure at
                    the main Location;

          2.1.3     to copy the Program Documentation to the extent reasonably
                    required for its lawful use of the Licensed Programs; and

          2.1.4     to engage a Relevant Third Party to provide disaster
                    recovery services or to undertake Interface Work for the
                    Licensee,

          on the terms and subject to the conditions of this Licence.

2.2       The Licence shall commence on the Commencement Date and shall continue
          without limit in time unless and until terminated in accordance with
          clause 16.

3.        CHARGES AND TERMS OF PAYMENT

3.1       The Licence Fee shall be paid on the Commencement Date. The Disaster
          Recovery Service Fee shall be paid on the issue of a copy of the
          Licensed Program Materials to the Relevant Third Party under clause
          6.4.

3.2       The Licensee reserves the right to withhold payment against any
          invoice which is not submitted in accordance with this Licence, and
          shall forthwith notify to the Licensor in writing the reasons for
          withholding payment.

3.3       If the Licensee disputes the whole or any part of any invoice from the
          Licensor, the Licensee shall pay that amount of the invoice which is

          resolution of the dispute. Any amounts withheld, but subsequently
          found to be properly payable following the resolution of the dispute,
          will carry interest (as well after as before judgment) from (and
          including) the last date for

<PAGE>


          payment thereof to (but excluding) the date of actual payment at a
          rate equivalent to 2% over Barclays Bank PLC's base lending rate then
          in force.

3.4       If the payment of any sum due under the Licence shall be delayed by
          the Licensee other than in accordance with clauses 3.2 and 3.3, the
          Licensor shall be entitled to charge interest at a rate equivalent to
          2% over Barclays Bank PLC's base lending rate then in force, on the
          amount of the delayed payment for the period of the delay.

3.5       If any payment under this clause 3 would be due on a non-Business Day,
          the payment obligation shall be deferred until the next Business Day.

3.6       The Licence Fee and the Disaster Recovery Service Fee shall be paid in
          US dollars and all other charges payable in connection with the
          Licence shall be paid in GB sterling.

3.7       The Licensor shall be entitled to request the Licensee to make payment
          of the Licence Fee and the Disaster Recovery Service Fee direct to a
          third party including ABB (Systems Control Division) or as such third
          party may direct. If the Licensee makes such payment in accordance
          with the Licensor's instructions, the Licensee shall certify that
          payment has been made, and such payment shall discharge the Licensee's
          obligations under this Licence in so far as they relate to that
          payment.

3.8       All payments to the Licensor under the terms of this Licence are
          expressed to be exclusive of Value Added Tax howsoever arising. The
          Licensee shall pay to the Licensor in addition to those payments, or
          if earlier on receipt of a tax invoice or invoices from the Licensor,
          all Value Added Tax in relation to any supply made or deemed to be
          made for Value Added Tax purposes pursuant to this Licence.

3.9       If the Licensee is required under applicable law to deduct withholding
          tax or any other UK taxes from any sums payable to the Licensor under
          this Licence then the Licensee shall be entitled to do so, provided
          that the Parties shall co-operate and take reasonable steps lawfully
          to avoid making any such deduction. In the event that it is not
          possible lawfully to avoid making such deduction, the Licensee shall
          increase the sum payable to the extent necessary to ensure that, after
          the making of such deduction or withholding, the Licensor receives on
          the due date of such payment (and retains, free from any liability in
          respect of such deduction or withholding), a net sum equal to the sum
          which it would have received had no such deduction or withholding been
          required to be made. The Licensee shall promptly deliver to the
          Licensor any receipts, certificates or other proof evidencing the
          amounts (if any) paid or payable in respect of any deduction or
          withholding as aforesaid.

3.10      If any increased amount is paid pursuant to the above clause, then if
          in its sole opinion and without prejudice to the rights of the
          Licensor to manage its tax affairs as it thinks fit the Licensor
          determines that it has received or been granted a credit against or
          relief or remission from or repayment of any tax paid or payable by it
          in respect of or calculated with reference to the deduction or
          withholding giving rise to the payment of such increased amount ("the
          Benefit"), the Licensor shall, to the extent it can do so without
          prejudice to the retention of such credit, relief, remission or
          repayment, pay to the Licensee the amount of the Benefit.

                    Kingdom export laws and controls in force from time to time;
                    and

<PAGE>


          5.2.2     in any event, not to export copies of the Licensed Program
                    to other Locations outside the European Union or the USA
                    without the prior written consent of the Licensor (not to be
                    unreasonably withheld).

5.3       The Licensee shall, and shall procure that any Relevant Third Party
          shall, follow all reasonable instructions given by the Licensor from
          time to time with regard to the use of the Licensed Program Materials.
          The Licensee shall, and shall procure that any Relevant Third Party
          shall, permit the Licensor, at all reasonable times, and at the
          Licensor's expense, to do all acts and things (including entering onto
          any premises) necessary to verify that the use of the Licensed Program
          Materials is within the terms of this Licence, provided:

          5.3.1     that in doing so the Licensor shall not act in any manner
                    which will interfere with, or disrupt, the normal operations
                    of the Licensee in carrying out the functions of the
                    Settlement System Administrator in connection with the
                    Electricity Pool of England and Wales; and

          5.3.2     that the Licensor shall only exercise its right of entry
                    where it has reasonable grounds to believe that the Licensee
                    or a third party is in breach of the terms of this Licence.

6.        DISASTER RECOVERY AND INTERFACE WORK

6.1       Prior to engaging a third party to provide disaster recovery services,
          the Licensee shall notify the Licensor in writing of its intention to
          do so, and of the identity of the third party.

6.2       Subject to the proviso set out below, within 30 days of such notice,
          the Licensor shall either:

          6.2.1     approve the third party to provide disaster recovery
                    services, in which event that third party shall be treated
                    as a "Relevant Third Party"; or

          6.2.2     reject the third party,

          PROVIDED that approval shall not be unreasonably withheld and that
          failure to reject the third party within such 30 day period shall be
          treated as approval.

6.3       Prior to engaging a third party to assist the Licensee in ensuring
          that the Licensed Program will be interoperable with other computer
          programs used by the Licensee ("Interface Work"), the Licensee shall
          notify the Licensor in writing of its intention to do so, and of the
          identity of the third party. Such third party shall be treated as a
          "Relevant Third Party" for the purposes of this Agreement.

6.4       The Licensee may issue a copy of the Licensed Program Materials to a
          Relevant Third Party solely for the purposes of providing disaster
          recovery services to or undertaking Interface Work for the Licensee,
          subject to (in the case of disaster recovery services only):

<PAGE>


          6.4.1     the Licensee having paid the appropriate Disaster Recovery
                    Service Fee; and

          6.4.2     the Relevant Third Party having entered into a
                    confidentiality agreement with the Licensee in the form set
                    out in the Appendix and provided a copy to the Licensor.

6.5       The Relevant Third Party may make such copies of the Licensed Program
          as it reasonably requires for back-up purposes, provided that (in the
          case of disaster recovery services only) copies may only be retained
          at an additional Location where the Licensee has paid the appropriate
          Disaster Recovery Service Fee.

7.        SECURITY

7.1       The Licensee undertakes that the Licensed Program Materials and all
          copies of the Licensed Program made by the Licensee pursuant to clause
          2.1 and by a Relevant Third Party pursuant to clause 6.5 will remain
          under the control of the Licensee or the Relevant Third Party as the
          case may be, and that the Licensee will take, and will procure that a
          Relevant Third Party will take, all reasonable precautions to
          safeguard the Licensed Program Materials against unauthorised use. In
          particular, the Licensee shall, and shall procure that any Relevant
          Third Party shall, maintain a standard of care in protecting the
          Licensed Program Materials against theft, unauthorised access and use,
          which is not less than the standard that the Licensee employs itself
          in the protection of its own and/or other licensed computer programs
          and confidential information.

7.2       If the Licensee or any Relevant Third Party sells or disposes of any
          equipment on which a copy of the Licensed Program has been loaded
          (other than to a successor Settlement System Administrator to whom it
          also assigns this Licence in accordance with clause 12), the Licensee
          shall ensure and shall procure that any Relevant Third Party shall
          ensure that all copies of the Licensed Program have previously been
          deleted.

7.3       The Licensee shall not, and shall procure that any Relevant Third
          Party shall not:

          7.3.1     (subject to Section 296A of the Copyright Designs and
                    Patents Act 1988) disassemble or reverse engineer the
                    Licensed Program; or

          7.3.2     (subject to Section 50B of the Copyright Designs and Patents
                    Act 1988) decompile the Licensed Program.

7.4       The Licensee shall not and shall procure that any Relevant Third Party
          shall not translate, adapt, vary, or modify the whole or any part of
          the Licensed Program or attempt any error correction of the whole or
          any part of the Licensed Program or permit the whole or any part of
          the Licensed Program to be combined with or become incorporated in any
          other computer programs. For the avoidance of doubt, the use of
          interfaces to the Licensee's other computer programs shall not be
          regarded as "combining" or "incorporating", and the restrictions set
          out in this clause 7.4 shall not prevent the exercise by the Licensee
          of its rights and the performance by the Licensee of its obligations
          under clause 4.2.

8.        PROGRAM DOCUMENTATION COPYING

8.1       The Licensee shall procure that any Relevant Third Party shall not
          make any copies of the Program Documentation.

9.        EQUIPMENT UPGRADES

9.1       The Licensor shall notify the Licensee of any upgrades to the
          Equipment required to ensure satisfactory running of any future
          release or version of the Licensed Program.

10.       WARRANTIES

10.1      The Licensor warrants and undertakes that, provided it is operated in
          accordance with the Licensor's instructions and on the Equipment, the
          Licensed Program will for a period of 90 days from the Delivery Date
          (or if later, from the date of actual delivery of the Licensed Program
          Materials) ("the Warranty Period") conform in all material respects to
          the Specification existing at the Delivery Date. The Licensor does not
          guarantee that the Licensed Program is free of errors not materially
          affecting such conformity.

10.2      The Licensor warrants and undertakes that it shall fulfil its delivery
          and rectification obligations hereunder with all due reasonable care
          and skill and by suitably qualified and trained personnel.

10.3      Each Party represents and warrants to the other that so far as it is
          aware, all software and data it transfers to the other shall be free
          from all logic bombs, viruses, or other contaminants (including worms
          or trojan horses) or any self-propagating or other programs that may
          affect or cause damage to the software, data or systems belonging to
          or used by that other.

10.4      The Licensor represents and warrants:

          10.4.1    that it owns the Intellectual Property rights in the
                    Licensed Program Materials or has otherwise obtained full
                    right to grant the Licence to the Licensee; and

          10.4.2    that so far as it is aware, the use of the Licensed Program
                    or part thereof by the Licensee shall not infringe the
                    Intellectual Property rights of a third party.

10.5      The Licensor represents and warrants that the Licensed Program will
          be, and will remain, Millennium Compliant and will not cease to be so
          at or at any time prior to, during or after the year 2000. For the
          purposes of this warranty, "Millennium Compliant" means that neither
          the performance nor the functionality of the Licensed Program is or
          will be affected by dates prior to, during or after the year 2000, and
          in particular that the Licensed Program has the following features:

          10.5.1    no value for current date causes or will cause any
                    interruption in operation;

          10.5.2    database functionality behaves and will behave consistently
                    for dates prior to, during and after the year 2000;

<PAGE>


          10.5.3    in all interfaces and data storage, the century in any date
                    is and will be specified either explicitly or by unambiguous
                    algorithms or inference rules; and

          10.5.4    the year 2000 is and will be recognised as a leap year,

          provided that the Licensor shall have no liability in respect of
          defects in performance or functionality caused by incorrect or
          non-millennium compliant data or software originating outside the
          Licensor.

10.6      Subject to clause 10.7, if the Licensor receives written notice from
          the Licensee that the Licensed Program does not materially conform to
          the warranties set out in this clause 10, the Licensor's sole
          obligation (at its own expense) shall be:

          10.6.1    in the case of any of the Licensed Program the Intellectual
                    Property rights in which are vested in the Licensor, to
                    remedy such material non-conformity of the relevant portion
                    so as to conform materially with the relevant warranty; and

          10.6.2    in the case of any of the Licensed Program the Intellectual
                    Property rights in which are vested in a third party, either
                    to obtain and supply a corrected version so as to conform
                    materially with the relevant warranty or to remedy itself
                    such material non-conformity of the relevant portion so as
                    to conform materially with the relevant warranty.

10.7      The Licensor shall have no obligations or liability under clause 10
          unless it has first received written notice of the breach of warranty
          no later than:

          10.7.1    expiry of the Warranty Period (in the case of a breach of
                    clause 10.1);

          10.7.2    90 days from the date on which the Licensee became aware of
                    the breach (in the case of a breach of clauses 10.2, 10.3 or
                    10.4); or

          10.7.3    2nd January, 2001 (in the case of a breach of clause 10.5).

10.8      The warranties and undertakings set out in this clause 10 shall be
          subject to the Licensee complying with its material obligations under
          this Licence. When notifying any material non-conformity of the
          Licensed Program the Licensee shall, so far as it is able, provide the
          Licensor with documented examples of such material non-conformity.

10.9      Clause 10 constitutes the only warranties provided by the Licensor in
          respect of the Licensed Program. The obligations and liability of the
          Licensor in this Licence are in place of, and the Licensee accordingly
          waives, all implied guarantees and warranties including, without
          limitation, any warranty of satisfactory quality or fitness for a
          particular purpose whether or not any particular purpose has been
          notified to the Licensor. The Licensor shall have no liability under
          this Licence in respect of defects and/or derogations set out in the
          Technical Compliance Report.

11.       OWNERSHIP

11.1      The Intellectual Property rights subsisting in the Licensed Program
          Materials and all parts and copies thereof shall remain vested in the

          Licensor has been granted an appropriate licence or sub-licence.

                    and rights of the Licensor or, as the case may be, any third
                    party from which the Licensor has been granted an
                    appropriate licence or sub-licence; and

          11.2.2    affix any and all Intellectual Property notices affixed to
                    the Licensed Program Materials on any and all copies made by
                    the Licensee pursuant to clause 2.1 and a Relevant Third
                    Party pursuant to clause 6.5 and shall ensure that any such
                    notices shall not be tampered with, removed or obscured in
                    any manner whatsoever.

12.       ASSIGNMENT

12.1      The Licensor shall not assign any of its obligations under the Licence
          without the prior written consent of the Licensee, except that the
          Licensor shall have the right to assign this Licence to any
          organisation which is to carry on the business of Grid Operator
          currently carried out by the Licensor as part of a solvent
          reconstruction or amalgamation of the Licensor, provided always that

          Licensee to be bound by the terms of this Licence.

12.2      Subject to clause 12.3, the Licensee shall not be entitled to assign

13.       INDEMNITIES

13.1      The Licensor shall fully indemnify the Licensee against all damages,
          costs, charges and expenses arising from or incurred by reason of any
          infringement or alleged infringement in the United Kingdom of
          copyright in consequence of the authorised use or possession by the
          Licensee of Licensed Program Materials, subject to the following:

          13.1.1    the Licensee shall notify the Licensor forthwith in writing
                    if it becomes aware of any alleged infringement;

                    prior written consent; and

          13.1.3    the Licensee, at the Licensor's request and expense, shall
                    allow the Licensor to conduct any negotiations or litigation
                    and/or settle any claim. The Licensee shall give the
                    Licensor all reasonable assistance. The costs incurred or
                    recovered in such negotiations or settled claim shall be for
                    the Licensor's account.

13.2      If at any time an allegation of infringement of copyright is made in
          respect of the Licensed Program Materials, or if in the Licensor's
          reasonable opinion such an allegation is likely to be made, the
          Licensor may at his own expense modify or replace the Licensed Program
          Materials so as to avoid the infringement, without detracting from
          overall performance, the Licensor making good to the Licensee any loss
          of use during modification or replacement.

          subject to the following:

          13.3.1    the Licensor shall notify the Licensee forthwith in writing
                    if it becomes aware of any alleged breach; and

                    licensors without the prior written consent of the Licensee
                    (not to be unreasonably withheld or delayed).

14.       LIMITATION OF LIABILITY

14.1      Subject to clause 14.2 and save where any provision of this Licence
          provides for an indemnity, neither Party (the "Party Liable") nor any
          of its officers, employees or agents shall be liable to the other
          Party for loss arising from any breach of this Licence, other than for
          loss directly resulting from such breach and which at the Commencement
          Date was reasonably foreseeable in respect of:

          14.1.1    physical damage to the property of the other Party, its
                    officers, employees or agents; and/or

                    loss in respect of physical damage.

14.2      Nothing in this Licence shall exclude or limit the liability of the
          Party Liable for death or personal injury resulting from negligence.

          its officers, employees or agents from and against any such loss or
          liability resulting from the negligence of the Party Liable or any of
          its officers, employees or agents.

14.3      Subject to clause 14.2, and save where any provision of this Licence
          provides for an indemnity neither the Party Liable nor any of its
          officers, employees or agents shall in any circumstances whatsoever be
          liable to the other Party for:

          14.3.1    any loss of profit, loss of revenue, loss of use, loss of
                    contract or loss of goodwill; or

                    consequences of any of the foregoing; or

          14.3.3    any indirect or consequential loss; or

          14.3.4    loss resulting from the liability of the other Party to any
                    other person howsoever and whensoever arising save as
                    provided in clauses 14.1 and 14.2.

14.5      Each of the clauses of this clause 14 shall:

          14.5.1    be construed as a separate and severable Licence term and if
                    one or more of such clauses is held to be invalid, unlawful
                    or otherwise unenforceable the other sub-clause or
                    sub-clauses, as the case may be, shall remain in full force
                    and effect and shall continue to bind the Parties; and

          14.5.2    survive termination of this Licence.

14.6      For the avoidance of doubt nothing in this clause 14 shall prevent or
          restrict either Party enforcing any obligation (including suing for a
          debt) owed to it under or pursuant to this Licence.

14.7      Except for the liabilities described in clause 14.2, each Party's

15.       INSURANCE

15.1      Without thereby limiting its responsibilities under this Licence, the

18.3      Each Party shall adopt procedures within its organisation for ensuring
          the confidentiality of all Relevant Information. These procedures are:

          18.3.1    the Relevant Information will be disseminated only on a
                    "need to know" basis;

          18.3.2    directors, employees, agents, consultants and advisers will
                    be made fully aware of that Party's obligations of
                    confidence in relation thereto; and

          18.3.3    any copies of the Relevant Information, whether in hard copy
                    or computerised form, will clearly state that the Relevant

18.4      The obligations of both Parties contained in this clause 18 shall come
          into effect on the Commencement Date and shall continue in force

                    Party owed to the Non-Performing Party which the other Party
                    is unable to carry out directly as a result of the
                    suspension of the Non-Performing Party's obligations,

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

<PAGE>

                    no longer duration than is required by the Force Majeure;

          (ii)      no obligations of any Party are excused as a result of the
                    Force Majeure; and

                              the period of Force Majeure; and

                    (b)       the Non-Performing Party uses all reasonable
                              efforts to remedy its inability to perform.

19.2      As soon as practicable after the occurrence of the Force Majeure the
          Non-Performing Party shall discuss with the other Party how best to
          continue its operations and give effect to its obligations so far as
          possible in accordance with this Licence.

20.       EXPERT'S DECISION

          in the case of negligence or manifest error.

          quasi judicial procedure and the Parties shall have no right of appeal
          against the expert's decision, provided always that this shall not be

          expert for breaching his terms of appointment or otherwise being
          negligent.

          power, privilege or remedy under this Licence shall operate to impair
          such right, power, privilege or remedy or be construed as a waiver
          thereof. Any single or partial exercise of any such right, power,

          thereof or the exercise of any other right, power, privilege or
          remedy.

23.2      The rights and remedies provided by this Licence to the Parties are

          including without limitation any rights either Party may possess in
          tort which shall include actions brought in negligence and/or
          nuisance. Accordingly, each of the Parties hereby waives to the

          common law or statute, and releases the other Party, its officers,
          employees and agents to the same extent from all duties, liabilities,
          responsibilities or obligations provided by common law or statute in
          respect of the matters dealt with in this Licence and undertakes not

24.       SEVERANCE OF TERMS

If for any reason whatever any provision of this Licence is or becomes invalid,
illegal or unenforceable, or is declared by any court of competent jurisdiction
or any other Competent Authority to be invalid, illegal or unenforceable or if
such Competent Authority:

24.1      refuses, or formally indicates an intention to refuse, authorisation
          of, or exemption to, any of the provisions of or arrangements
          contained in this Licence (in the case of a refusal either by way of
          outright refusal or by way of requiring the amendment or deletion of
          any provision of this Licence and/or the inclusion of any provision in
          this Licence and/or the giving of undertakings or the acceptance of
          conditions as to future conduct before such authorisation or exemption
          can be granted); or

24.2      formally indicates that to continue to operate any provision of this
          Licence may expose the Parties to sanctions under any law, order,
          enactment or regulation, or requests either

<PAGE>


          Party to give undertakings or to accept conditions as to future
          conduct in order that such Party may not be subject to such sanctions

and, in all cases, whether initially or at the end of any earlier period or
periods of exemption then, in any such case, the Parties will negotiate in good
faith with a view to agreeing one or more provisions which may be substituted
for such invalid, unenforceable or illegal provision which substitute
provision(s) is(are) satisfactory to the Competent Authority(ies) and produce(s)
as nearly as is practicable in all the circumstances the appropriate balance of
the commercial interests of the Parties.

25.       ENTIRE AGREEMENT

This Licence contains or expressly refers to the entire agreement between the
Parties with respect to the subject matter hereof and expressly excludes any
warranty, condition or other undertaking implied at law or by custom and
supersedes all previous agreements and understandings between the Parties with
respect thereto and each of the Parties acknowledges and confirms that it does
not enter into this Licence in reliance on any representation, warranty or other
undertaking not fully reflected in the terms of this Licence.

to the other hereunder shall be in the English language.

27.       JURISDICTION

27.1      Subject and without prejudice to clauses 20 and 27.3, each of the
          Parties irrevocably agrees that the courts of England are to have
          exclusive jurisdiction to settle any disputes which may arise out of
          or in connection with this Licence and that accordingly any suit,
          action or proceeding (together in this clause 27 referred to as
          "Proceedings") arising out of or in connection with this Licence may
          be brought in such courts.

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

27.3      For the avoidance of doubt nothing contained in the foregoing
          provisions of this clause 27 shall be taken as permitting a Party to
          commence Proceedings in the courts where this Licence otherwise
          provides for Proceedings to be referred to arbitration.

28.       GOVERNING LAW

This Licence shall be governed by, and construed in all respects in accordance
with, English law.

                    Requirements for SAV (NGC/GRP/579A10.1).

          The fee for this service will be agreed between NGC and the licensee
          on a case by case basis provided that where support and maintenance
          consists of items (A) and (B) only, the fee for such support and
          maintenance service shall be (pound)5,000 per annum increasing in line
          with inflation each year from the Goal Effective Date.

8.        WARRANTIES

9.        ASSIGNMENT

          Assignment of SAV Licence by the licensee will be conditional on
          receiving the consent of NGC's head licensors and NGC will use
          reasonable endeavours to obtain such consent.

10.       LICENCE UPGRADE

          NGC will use reasonable endeavours subject to agreement in relation to

          10.1.1    assist the licensee to transfer from one type of SAV Licence
                    to another if so required; and

          10.1.2    procure that any consideration payable by the licensee for
                    such transfer shall be the difference in the licence fees
                    set out in Table 3.1 above relating to the original and new
                    licences.

11.       LIMITATION OF LIABILITY

                    damages, costs, charges or expenses payable to or in
                    relation to any claim arising from or incurred by reason of
                    any breach of the SAV Licence (other than for breach by
                    NGC); and

          11.1.2    reasonable legal costs incurred in relation to any such
                    claim

          provided that if any claim is made against a SAV Licensee by NGC, NGC
          shall, subject to the payment of its reasonable costs and expenses in
          connection therewith, use its reasonable endeavours to negotiate with
          the applicable head licensors so as to minimise

<PAGE>


          the amount of damages, costs, charges or expenses payable to such head
          licensors in respect of any such claim.

11.2      The total aggregate liability of all SAV Licensees to NGC for all
          liabilities as described in paragraph 11.1 (whenever arising):

          11.2.1    under paragraph 11.1.1 shall be limited to US$5,000,000.

          11.2.2    under paragraph 11.1.2 shall be limited to US$1,000,000.

11.3      The caps set out in 11.2.1 or 11.2.2, as the case may be, shall be
          reduced by an amount equal to any moneys paid by any SAV Licensee to
          NGC under paragraph 11.1.1 or 11.1.2, as the case may be.

11.4      The cap on NGC's liability to the SAV Licensee for breach of the SAV
          Licence will be equal to US$6,000,000 divided by the number of SAV
          Licences in force from time to time.

11.5      The provisions of this paragraph 11 shall be without prejudice to the
          principles set out in clauses 25.1 and 25.2 in respect of physical
          damage to property, liability to third parties in respect of physical
          damage and death and personal injury.

12.       REVIEW OF ELECTRICITY TRADING ARRANGEMENTS

12.1      The provisions of this paragraph 12 shall only apply where the SAV
          Licensee is not a party to the Agreement.

12.2      The parties acknowledge that reviews of the electricity trading
          arrangements may result in changes to the existing electricity trading
          arrangements and such changes may require amendments to the provisions
          of the SAV Licences including the scope of use provisions.

12.3      Subject to paragraph 12.4, if at any time during, or upon the
          finalisation of, the review of the electricity trading arrangements
          referred to in paragraph 12.2, the existing electricity trading
          arrangements are changed as part of that review and the position under
          the SAV Licences is thereby affected, and NGC will continue to use
          Goal to assist in the function of central scheduling of generation or
          to use Goal (in whole or in part) as part of the interface between
          generators and NGC and the SAV Licensee wishes to continue to utilise
          Goal, then, upon written notice from either of them, NGC and the SAV
          Licensee shall negotiate in good faith amendments to the SAV Licence
          subject to prior discussions with the Executive Committee (including
          amendments to the scope of use of the relevant SAV Licence and
          provided that any proposed increase in licence fees shall be limited
          to such increase in fees which are required by a head licensor) so as
          to enable the SAV Licensee to model the output of the central
          scheduler and to ensure that data is compliant with the interface. The
          agreement of NGC and the SAV Licensee to such amendments shall not be
          unreasonably withheld or delayed. In the event of a failure to agree
          any such amendment within 90 days (or such longer period as shall be
          agreed by NGC and the SAV Licensee) after receipt by NGC or the SAV
          Licensee, as the case may be, of the written notice initiating the
          negotiation, either NGC or the SAV Licensee may (at any time
          thereafter) refer the matter to arbitration pursuant to the
          arbitration rules of the

<PAGE>


          Electricity Arbitration Association in force from time to time.
          Pending determination of that reference, the relevant SAV Licence
          shall continue in effect.

12.4      To the extent that the amendments agreed pursuant to paragraph 12.2
          require the consent of any head licensor of NGC, then NGC shall,
          subject to the payment of its reasonable costs and expenses in
          connection therewith, use its reasonable endeavours to obtain the
          consent of such head licensors to any such amendment.

13.       TERMINATION

13.1      NGC will have the additional right to terminate a SAV Licence in the
          following circumstances:

          13.1.1    for material breach by the licensee;

          13.1.2    (in the case of a SAV Licence that is a Type 2 Goal Licence)
                    in the event of the licensee ceasing to be a Party;

          13.1.3    (in the case of a SAV Licence that is a Type 5 Goal Licence
                    or a Type 6 Goal Licence) in the event that the licensee
                    ceases to be an affiliate of a Pool Member;

          13.1.4    in the event that NGC ceases to use Goal to assist in the
                    function of central scheduling of generation or to use Goal
                    (in whole or in part) as part of the interface between
                    generators and NGC;

          13.1.5    (in the case of a SAV Licence which is a Type 8 Goal Licence
                    or a Type 9 Goal Licence) in the event that the licensee
                    ceases to be a member of a Pool Member Group; and

          13.1.6    in the event that the arbitrator for the reference pursuant
                    to paragraph 12.3 or sub-section 2.2 of Schedule 35, as the
                    case may be, determines as part of his decision that the SAV
                    Licence should terminate.

13.2      Notwithstanding the foregoing, the SAV Licence shall not be terminated
          solely by reason of:

          13.2.1    the termination or expiry of any head-licence (including,
                    without limitation, those with Stanford and ABB) held by
                    NGC; or

          13.2.2    NGC ceasing to perform the functions of the Grid Operator.

          sub-contractors, from the obligations of confidentiality contained in
          this Clause 7.

8.        Intellectual Property Rights

                                   APPENDIX 4

         PRINCIPLES APPLYING TO TYPE 1 SUPPORT AND MAINTENANCE AGREEMENT

1.        INTRODUCTION

          This Appendix sets out the principal terms of the Type 1 Support and
          Maintenance Agreement to be entered into by NGC and the Settlement
          System Administrator in connection with the Type 1 Goal Licence.

2.        DESCRIPTION OF MAINTENANCE SERVICES

          The basic maintenance services comprise (i) assistance with critical
          problems, (ii) error correction, Emergency Fixes and provision of
          corrections to the Licensee and (iii) provision of a telephone
          helpline.

3.        LICENSEE's OBLIGATIONS

          In order that NGC can properly provide the maintenance services, the
          licensee will be required to undertake certain obligations with regard
          to the use of the licensed program. By way of example these will
          include undertaking (i) to keep full security copies of its own
          databases and computer records, (ii) not to permit anyone other than
          NGC to provide maintenance services and (iii) to co-operate fully with
          NGC in the diagnosis of any error or defect.

4.        CHARGES

          The annual fee for the maintenance services will be agreed by NGC and
          the Settlement System Administrator based on normal commercial
          principles and shall increase in line with inflation each year from
          the date of the Type 1 Support and Maintenance Agreement. Any
          additional support or consultancy services requested by the licensee
          will be charged at rates to be agreed between the parties.

5.        WARRANTIES

          NGC will undertake to fulfil its obligations with reasonable care and
          skill and by suitably qualified and trained personnel.

6.        ASSIGNMENT

          Assignment of the Type 1 Support and Maintenance Agreement may not be
          done separately from assignment of the Type 1 Goal Licence.

          4.1.3     that the Confidential Information will be treated and
                    safeguarded as private and confidential to the same level as
