                   ARTICLE III    ELECTION TO DEFER COMPENSATION

3.1  DEFERRAL ELECTION.

     (a)  Each Eligible Employee who desires to defer Compensation otherwise
          payable for a Plan Year may do so by filing a deferral election with
          the Plan Administrator during the Enrollment Period for that Plan
          Year. The election shall be made on the form specified by the Plan
          Administrator and shall be irrevocable after the end of the Enrollment
          Period. To be effective, the form must be received by the Plan
          Administrator prior to the end of the Enrollment Period.

     (b)  Notwithstanding the foregoing, the Plan Administrator may, in his or
          her sole discretion, permit an Eligible Employee who commences
          Employment during a Plan Year to submit a deferral election for
          Compensation payable during such Plan Year, provided such election is
          submitted no later than 30 days after Employment commences and applies
          only to Compensation earned after the date such form is received by
          the Plan Administrator.

3.2 AMOUNT OF COMPENSATION WHICH MAY BE DEFERRED. Each Eligible Employee may
defer, at the Plan Administrator's discretion, a portion of Salary and/or
Incentive Award otherwise payable for the Plan Year immediately following the
Enrollment Period. From time to time the Plan Administrator shall establish
maximum deferral percentages for Salary and Incentive Award deferrals.

3.3 DEFERRAL OF COMPENSATION. Notwithstanding Section 3.1 above, the Committee
shall have the discretion to deny any Eligible Employee's Deferral Election for
any given Plan Year or portion of a Plan Year. The Employer shall withhold
payment of the applicable portion of each Salary payment and/or each Incentive
Award elected by the Participant to be deferred for the Plan Year for those
deferral elections which the Committee does not deny. The deferred Compensation
shall be credited to the Participant's Deferred Compensation Account as
described in Article IV.

3.4 WITHHOLDING. Notwithstanding any other provision of the Plan to the
contrary, the Plan Administrator may establish procedures applicable to satisfy
FICA or other required withholding that may arise at the time a deferral is
allocated to a Participant's Account. These procedures may call for such
withholding to be satisfied either (i) by reducing a Participant's deferral
prior to such amount being allocated to the Participant's Account, (ii) by
reducing other compensation payable to the Participant at or about the same time
the deferral is allocated to a Participant's Account, or (iii) by receiving a
check or other payment from the Participant for the amount(s) due.

3.5 VESTING. All amounts deferred under the Plan, and any earnings thereon,
shall be fully vested at all times.

          ARTICLE IV   DEFERRED COMPENSATION ACCOUNT AND CREDITS THERETO

4.1 DEFERRED COMPENSATION ACCOUNT. An unfunded bookkeeping account known as the
Deferred Compensation Account shall be established for each Participant. The
Deferred Compensation Account shall be credited with (i) all deferred amounts
credited under an Other Plan as of the Other Plan Transfer Date, and (ii) all
amounts deferred under Article III of the Plan. The amounts credited to a
Participant's Deferred Compensation Account, as reduced for amounts distributed
under Article V, shall be adjusted each Crediting Date to reflect gain or loss
from the Investment Options.

4.2 ALLOCATION OF OTHER PLAN ACCOUNT BALANCES ON THE OTHER PLAN TRANSFER DATE.
The amount credited to a Participant under an Other Plan as of the Other Plan
Transfer Date shall be allocated among the Investment Options according to
guidance provided by the Participant to the Plan Administrator using a special
election form provided by the Plan Administrator for such purpose. If
Participant fails to elect an Investment Option or Options prior to the Other
Plan Transfer Date or for any subsequent Plan Year, the Plan Administrator has
the discretion to select an Investment Option or Options for the Participant.

4.3  ALLOCATION OF NEW DEFERRALS AMONG INVESTMENT OPTIONS AND TRANSFERS AMONG
INVESTMENT OPTIONS.

     (a)  During the Enrollment Period, the Participant shall elect how
          deferrals during the applicable Plan Year are to be allocated among
          the available Investment Options using forms and procedures
          established by the Plan Administrator for such purpose.

     (b)  Each Participant may reallocate his or her accumulated Deferred
          Compensation Account or deferrals among the Investment Options only
          during times approved by the Plan Administrator and using forms and
          procedures established from time to time by the Plan Administrator for
          such purpose. Any changes a Participant makes shall become effective
          on the next Crediting Date following the Plan Administrator's
          acceptance of the Participant's reallocation election.

4.4 PAYMENTS DEDUCTED ON A PRO-RATA BASIS FROM EACH INVESTMENT OPTION. Lump
sums, installments, or any other distributions from the Deferred Compensation
Account shall be deducted from the balance in each Investment Option on a pro
rata basis in proportion to the balance in each option using procedures
established by the Plan Administrator for such purpose.

4.5 CHANGE IN INVESTMENT OPTION. The Plan Administrator may change the
Investment Options available from time to time under the Plan. However, no such
change shall reduce a Participant's Deferred Compensation Account. If, following
a change in the Investment Options, the Participant fails to reallocate his or
her Account among the available Investment Options the Plan Administrator has
the discretion to select an Investment Option for the Participant.

               ARTICLE V    PAYMENT OF DEFERRED COMPENSATION ACCOUNT

5.1 FORM OF PAYMENT. The amounts credited to a Participant's Deferred
Compensation Account shall be paid in cash.

5.2 MANNER OF DISTRIBUTION. A Participant's Deferred Compensation Account shall
be distributed according to the procedures set forth below.

(a)  Distributions while employed. A Participant may elect to receive a
     distribution from their Account during their period of employment. Such
     election may either be for a Scheduled Distribution, or an Unscheduled
     Distribution, each as defined below.

     (i)    Scheduled Distribution. During the Enrollment Period when a
            Participant makes their deferral election, the Participant may
            specify a future Payment Date when the amount deferred or
            portion thereof will be distributed. To be valid, such future
            Payment Date must not be within 3 years of the Plan anniversary to
            which such election first applied, and such future Payment Date must
            precede the Participant's Termination Date. The amount distributed
            shall be allocated against the Investment Options as provided under
            Section 4.4. The Plan Administrator may disregard any invalid
            Scheduled Distribution election.

     (ii)   Unscheduled Distribution. During the Enrollment Period, a
            Participant may submit a written request to the Plan Administrator
            for an unscheduled distribution from their Account. If the Plan
            Administrator approves such request, the amount shall be payable
            upon the Payment Date following such approval. The amount
            distributed shall be subject to a 10% penalty, with the
            Participant's Account being debited an amount equal to 10% of the
            Unscheduled Distribution amount. The withdrawn amounts and the
            Unscheduled Distribution penalty shall be allocated against the
            Investment Options as provided under Section 4.4. Any Participant
            electing an Unscheduled Distribution during an Enrollment Period
            shall be considered ineligible to defer any Compensation under the
            Plan for the remainder of the Plan Year in which the Unscheduled
            Distribution occurs and for the next following Plan Year.

     (iii)  Notwithstanding the foregoing, no Covered Executive shall be
            eligible to make an election for either a Scheduled Distribution or
            Unscheduled Distribution, and the Plan Administrator is hereby
            empowered to disregard a Scheduled Distribution election made by a
            Participant at a time prior their first becoming a Covered
            Executive.

(b)  Distributions following employment. A Participant may receive either a
     Termination Distribution or a Retiree Distribution following their period
     of employment, each as defined below.

     (i)  Termination Distribution. A Participant who is not a Retirement
          Eligible Employee shall have their Account balance valued as of the
          Evaluation Date first following their Termination Date. Such balance
          shall be distributed in a lump sum on the Payment Date first following
          such Evaluation Date.

     (ii) Retiree Distribution. A Participant who is a Retirement Eligible
          Employee shall have their Account paid according to the following
          procedures:

          1)   Notwithstanding sections 2) and 3) below, if the Participant's
               Account, determined as of the first Evaluation Date following
               their Termination Date, is equal to or less than an amount
               established by the Plan Administrator from time to time (the
               "Minimum Installment Amount") such amount shall be distributed
               according to section (i) above.

                                     Page 8
<PAGE>   9

10/20/00

          2)   If the Participant has made an election as described in Section
               5.3 that has been in effect for at least twelve months prior to
               the Termination Date, the Participant's Account shall be paid in
               accordance with such payment election.

          3)   If the Participant does not have a payment election that has been
               in effect for at least twelve months prior to the Termination
               Date, the Participant's Account shall be paid in annual
               installments over a period of 10 years, as provided in the
               Section 5.3.

5.3 FORM OF PAYMENT ELECTION. Each Participant may submit a payment election
form specifying how the Participant's accumulated Deferred Compensation Account
shall be paid. The following distribution options shall be available:

(a)  Distributions following employment. A Participant who is a Retirement
     Eligible Employee, having an accumulated Account of at least the Minimum
     Installment Amount, as provided in Section 5.2(b)(ii) above, may elect
     their Account to be distributed in either of the following forms:

     (i)    Lump Sum Distribution. The amount payable shall equal the Account
            balance determined as of the Evaluation Date. Pursuant to the
            Participant's election, the Evaluation Date may be any Evaluation
            Date following the Termination Date. If the Participant fails to
            elect a date, the Evaluation Date will be the last day of the Plan
            Year in which the Termination Date occurs. The amount so determined
            shall be paid on the Payment Date next following such Evaluation
            Date.

     (ii)   Annual Installments. The amount of the first distribution shall be
            based on the Account balance as determined on the last Evaluation
            Date in the Plan Year in which the Participant's Termination Date
            occurs. Such amount shall be divided by the number of payments
            elected (being either 5 or 10, or other period as determined by the
            Plan Administrator) to determine the distribution. The distribution
            shall be made on the Payment Date next following such Evaluation
            Date. Subsequent distributions shall be determined annually
            thereafter using the procedure established herein, with the
            exception that the divisor shall be the number of payments
            remaining.

     (iii)  Participants not making a valid election shall have their Account
            distributed over a period of ten years as provided in Section
            5.3(a)(ii) above.

5.4 PLAN ADMINISTRATOR'S DISCRETION. The Plan Administrator shall have the
discretion to distribute the Account of any Participant who is not a Covered
Executive in a single distribution following their Termination Date. Such
distribution shall be based on the balance of the Participant's Account as of
the Evaluation Date immediately following their Termination Date. Such amount
shall be paid on the Payment Date next following such Evaluation Date.

5.5 PAYMENTS UPON DEATH OF PARTICIPANT.

     (a)  A Participant may designate any person or persons (not exceeding 5),
          including a trust, as his or her beneficiary to receive his or her
          Deferred Compensation Account in the event of the Participant's death.
          Any such designation shall be made by filing the form designated for
          that purpose by the Plan Administrator. The Participant may change or
          cancel his or her beneficiary designation at any time prior to death
          without the consent of any designated beneficiary. If no beneficiary
          has been designated by the Participant, or if no beneficiary is alive
          at the date of the Participant's death, payment shall be made to the
          Participant's estate.

     (b)  If the Participant's death occurs during Employment, the Participant's
          Account shall be distributed in a lump sum as provided in 5.3(a)(i) to
          each of the Participant's surviving beneficiaries in the portions
          designated by the Participant in 5.5(a).

          sum on the next scheduled Payment Date to each of the Participant's
          surviving beneficiaries in the portions designated by the Participant
          in 5.5(a).

distributions under the Plan any and all taxes required to be collected under
federal, state or local laws, using procedures established by the Plan
Administrator for such purpose.

                         ARTICLE VII   CLAIMS FOR BENEFITS

7.1  CLAIMS PROCEDURE.

     (a)  Claims Must be Filed. An Employee, Participant, beneficiary or estate
          of a deceased Participant (the "claimant") who has a claim for
          benefits or concerning any other matter under the Plan must give
          written notice of such claim or other matter to the Plan
          Administrator.

     (b)  Review of Claim. After the Plan Administrator has reviewed the claim
          and obtained any other information it deems necessary to render a
          decision on the claim, the Plan Administrator shall notify the
          claimant within 90 days after receipt of the claim of the acceptance
          or denial of the claim, unless special circumstances require an
          extension of time for processing the claim. Such an extension of time
          may not exceed 90 additional days and notice of the extension shall be
          provided to the claimant prior to the termination of the initial 90
          day period indicating the special circumstances requiring the
          extension and the date by which a final decision on the claim is
          expected.

     (c)  Denied Claims. In the event any application for benefits is denied, in
          whole or in part, the Plan Administrator shall notify the claimant of
          such denial in writing and shall advise the claimant of the right to
          appeal the denial and to request a review thereof. Such notice shall
          be written in a manner calculated to be understood by the claimant and
          shall contain:

          (1)  Specific reason for such denial.
          (2)  Specific reference to the Plan provisions on which such denial is
               based.
          (3)  A description of any information or material necessary for the
               Employee to perfect the claim.
          (4)  An explanation of why such material is necessary.
          (5)  An explanation of the Plan's appeal and review procedure.

7.2  APPEAL AND REVIEW PROCEDURE.

     (a)  Appeal to Committee. If the claimant's claim for benefits is denied in
          whole or in part, the claimant, or the claimant's duly authorized
          representative, may appeal the denial by submitting to the Plan
          Administrator a written request for review of the application by the
          Committee within 180 days after receiving written notice of such
          denial. The Plan Administrator shall give the applicant (upon request)
          an opportunity to review pertinent Plan documents (other than legally
          privileged documents) in preparing such request for review.

     (b)  Contents of Appeal. The request for review must be in writing and
          shall be addressed to the Committee c/o the Plan Administrator. The
          request for review shall set forth all of the grounds upon which it is
          based, all facts in support thereof and any other matters which the
          claimant deems pertinent. The Committee may require the claimant to
          submit (at the claimant's expense) such additional facts, documents or
          other material as the Committee deems necessary or advisable in making
          its review.

     (c)  Review of Appeal. The Committee shall act upon each request for review
          within 120 days after its receipt thereof unless special circumstances
          require further time for processing. Written notice of an extension of
          time beyond 120 days shall be furnished to the claimant prior to the
          commencement of the extension. In no event shall the decision on
          review be rendered more than 365 days after the Committee receives the
          request for review.

     (d)  Denied Appeals. In the event the Committee confirms the denial of the
          claim for benefits in whole or in part, it shall give written notice
          of its decision to the claimant. Such notices shall be written in a
          manner calculated to be understood by the claimant and shall contain
          the specific reasons for the denial.

                         ARTICLE VIII   GENERAL PROVISIONS

8.1 SOURCE OF PAYMENTS. The Deferred Compensation Accounts established under the
Plan are unfunded bookkeeping accounts and are payable from the general assets
of the Corporation. The Corporation is not required to physically segregate any
cash or securities or establish any separate funds to pay any benefits under the
Plan. Nothing in this Plan shall be deemed to create a trust or fund of any kind
or any fiduciary relationship.

8.2 PROHIBITION ON ALIENATION. No amount payable under the Plan shall be subject
to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance,
hypothecation, charge, attachment, garnishment, execution, or levy of any kind
or any other process of law, voluntary or involuntary. Any attempt to dispose of
any rights to benefits payable under the Plan shall be void. Notwithstanding the
preceding sentence, the Corporation shall have the right to offset from a
Participant's Account balance any amounts due and owing from the Participant to
the extent permitted by law. Notwithstanding the foregoing, the Corporation may
transfer a Participant's rights under the Plan to a successor entity in
connection with a sale, spin-off, or other similar event, if and only if the
successor entity agrees to enforce the terms and provisions hereof.

8.3 NOT A CONTRACT OF EMPLOYMENT. Participation in this Plan by an Employee
shall not give such Employee any right to be retained in the employ of the
Employer and the ability of the Employer to dismiss or discharge an Employee is
specifically reserved.

8.4 HEADINGS NOT TO CONTROL. Headings and titles within the Plan are for
convenience only and are not to be read as part of the text of the Plan.

8.5 SEPARABILITY OF PLAN PROVISIONS. If any provisions of the Plan are for any
reason declared invalid or not enforceable, such provisions will not affect the
remaining terms and conditions, but the Plan will be construed and enforced
thereafter as if such provisions had not been inserted.

8.6 APPLICABLE LAW. The validity and effect of the Plan and the rights and
obligations of all persons affected thereby, are to be construed and determined
in accordance with applicable federal law, and to the extent that federal law is
inapplicable, under the laws of the State of Ohio.

8.7 ENTIRE PLAN. This document is a complete statement of the Deferred
Compensation Plan and as of January 1, 2001 supersedes all representations,
prior plans, promises and inducements, proposals, written or oral, relating to
its subject matter. The Corporation shall not be bound by or liable to any
person for any representation, promise or inducement made by any person which is
not embodied in this document or in any authorized written amendment to the
Plan.

                      ARTICLE IX   AMENDMENT AND TERMINATION

9.1 AMENDMENT AND TERMINATION. The Corporation expects to continue this Plan
indefinitely, but reserves the right, by action of the Committee, to amend it
from time to time or to discontinue it if such change is deemed necessary or
desirable. However, if the Plan is amended by the Committee, the Corporation
shall remain obligated under the Plan with respect to each Participant's
Deferred Compensation Account (including the earnings, gains, and losses
thereon, if any) for which, as of the date of such action, have been credited or
debited to the Account. No such amendment, modification or termination shall
reduce the amount credited to a Participants' Accounts as of the date of such
action. Upon Plan termination, all amounts credited to Participants' Accounts
shall be paid to Participants in a single payment within 120 days.

IN WITNESS WHEREOF, National City Corporation, has caused this instrument to be
executed by its duly authorized officer, this 23rd day of October, 2000, to be

Core Industry Document, as amended pursuant hereto, shall be resolved in
accordance with the applicable provisions of that document.

4.8.3 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

1996 shall apply to any such arbitration wherever the same or any part of it
shall be conducted.

<PAGE>   13

arising out of or in connection with the Scheme may be brought (and may only be
brought) in such courts.

4.9.2 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

judgment in any proceedings brought in the English or Welsh courts shall be
conclusive and binding upon such Party and may be enforced in the courts of any
other jurisdiction.

shall immediately on becoming a Party (or upon ceasing to be a company so

at any time to provide such address, such Party shall be deemed to have
appointed BSCCo as its agent to accept service of process on its behalf until
and unless such Party provides BSCCo with an alternative address in England or
Wales for these purposes.

4.9.4 For the avoidance of doubt nothing contained in the foregoing provision of
this paragraph B4.9 shall be taken as permitting a Party to commence proceedings
in the courts where the Scheme otherwise provides for the proceedings to be
referred to arbitration or otherwise determined.

PART C - AMENDMENT OF CORE INDUSTRY DOCUMENTS

1. GENERAL

1.1 This Part C sets out or refers to amendments which are to be made to Core
Industry Documents (other than the P&SA, to which Part E applies) and sets out
steps to be taken (if any) by Parties for the purposes of making such
amendments.

1.2 Unless otherwise specified in this Part C, all amendments to Core Industry
Documents made or to be made pursuant to this Part C shall be made so as to take
effect on and from:

(a) the Go-live Date, or

(b) in relation to (but only to the extent necessary to give effect to)
provisions of the relevant document which (when so amended) will require or
entitle any Party to take steps before the Go-live Date for the purposes of
commencing trading under the BSC on the Go-live Date, such earlier time as is
appropriate for that purpose, but for the avoidance of doubt such amendments
shall not be made so as to vary or qualify the effect of such Core Industry
Documents as they apply or applied in respect of periods prior to the date with
effect from which such amendments are to be made.

1.3 This paragraph C1 applies to all Parties, and each other paragraph of this
Part C shall apply to the Party or Parties or classes of Party specified in that
paragraph (or, in the absence of any specification, to all Parties who are bound
by or have rights in respect of the Core Industry Document referred to in such
paragraph).

1.4 Without prejudice to the further provisions of this Part C, each Party:

(a) hereby agrees and acknowledges the amendment of each Core Industry Document
made or to be made pursuant to this Part C, and, accordingly, grants or waives
the requirement (if any) for its consent or approval to such amendment (and
waives the requirement for any procedural steps which are not provided for in
the Scheme); and

(b) shall take such further steps and do such further things within its power as
may be necessary in order to perfect the amendment of Core Industry Documents
pursuant to this Part C and shall facilitate the full and timely completion of
those amendments; and

(c) shall use all reasonable endeavours to procure any necessary consents and
approvals required to effect or give effect to the amendment pursuant to this
Part C of Core Industry Documents (to which such Party is party) from persons
who are not Parties

<PAGE>   15

(and to do so as soon as reasonably practicable after the Scheme Effective
Date); and

(d) shall discharge its obligations under this Part C as promptly and
expeditiously as reasonably possible; and

(e) shall not take any step or exercise any right which is intended to or the
effect of which (to the knowledge of such Party) is to hinder, frustrate or
delay the full and timely amendment of the Core Industry Documents made or to be
made under this Part C.

1.5 The requirements of, and obligations of Parties under, this Part C shall
continue in force after the Go-live Date to the extent to which any amendment
which is required to be made to a Core Industry Document under this Part C has
not been made by that date.

<PAGE>   16

1.6 Paragraph C1.2 shall apply in respect of any amendment to a Core Industry
Document made (pursuant to this Part C) after the Go-live Date; provided that
(without prejudice to the obligations of Parties under this Part C) this shall
not require such amendment to be made in a manner which would impose on any
Party an obligation such that:

(a) that Party would be in breach of that obligation, and

(b) that breach would be incapable of remedy by reason of the fact that the
amendment is to have retrospective force.

1.7 Any dispute as to whether an amendment is to be made in a particular manner
pursuant to paragraph C1.6 shall be referred to the Director General for
determination. 1.8 The Secretary of State may, before the Go-live Date,
designate further amendments to Core Industry Documents (as amended under the
Scheme):

(a) to take account of any modification to the Scheme made pursuant to the
Scheme Licence Conditions or to take account of any Transitional BSC
Modifications (made in any of the circumstances set out in paragraph G5.3); or

(b) to take account of any matters which emerge as a result of the testing and
trialling of computer systems and processes required to support the new
electricity trading arrangements envisaged by the Scheme; or

(c) to correct any errors or omissions in the amendments designated, on or
before the Scheme Effective Date, to Core Industry Documents pursuant to the
Scheme and/or to resolve any inconsistencies between the provisions of the BSC
and the Core Industry Documents (as so amended); or

(d) to make such changes as are necessary to ensure that the trading of
electricity under or by reference to the BSC can commence and take place, where
such trading would be prevented or materially hindered for the whole or a
substantial part of the relevant market, or where the operation of the relevant
market for such trading would be materially distorted, without such change; or

(e) to make any other minor consequential changes resulting from any of the
changes referred to in paragraphs (a) to (d). and in any such case to be made in
order to give (or continue to give) full and timely effect to the matters set
out in the Scheme Licence Conditions; and the provisions of this Part C shall
apply, mutatis mutandis, to any such further amendments (but so that references
to the making of such amendments on or within a specified period after the
Scheme Effective Date

<PAGE>   17

are replaced by references to the making of such amendments on or within such
specified period after the date when such further amendments are designated).

1.9 Before designating further amendments to Core Industry Documents under
paragraph C1.8, the Secretary of State shall consult Parties and such other
persons as he considers appropriate and, for this purpose:

(a) consultation may be by way of, inter alia , electronic communication; and

(b) the period for responses shall be such as the Secretary of State thinks fit,
taking into account the urgency, importance and complexity of the amendment but
shall, in any event, be not less than 2 working days.

<PAGE>   18

1.10 Where:

(a) a Party is required to take a step under this Part C; and

(b) such Party has already taken such step (in conformity with the provisions of
the Scheme) prior to the Scheme Effective Date, such step shall be deemed to
have been taken by such Party under the Scheme as at the Scheme Effective Date.

1.11 Where and to the extent that this Part C provides that a matter may or
shall be referred to the Director General or the Secretary of State (as the case
may be) for determination, the Parties agree that such reference shall be the
sole means of determining such matter and the Parties hereby waive any other
rights whatsoever they may have in respect of such matter (but subject to the
duties of the Director General and the Secretary of State at law).

pursuant to the authority conferred on NGC by the clause in the Supplemental
Agreement providing for variations.

currently used by NGC (by reference to which amendments are designated pursuant
to paragraph C4.1); and

established under the Scheme Licence Conditions, then such special provisions
are to be amended to incorporate the changes necessary to give effect to and to
be given effect in consequence of the coming into force, in place of the P&SA,
of the BSC as it is to take effect from the Go-live Date.

4.6 In respect of each Supplemental Agreement referred to in paragraph C4.5, NGC

reference to the pro forma of that type of ancillary services agreement
currently used by NGC).

5.2 Each Party which is party to an Ancillary Services Agreement hereby agrees

prejudice to any effect the exercise of that right may have in respect of any
Part 2 System Ancillary Services and Commercial Ancillary Services).

to Part 1 System Ancillary Services, which:

agreement currently used by NGC (by reference to which amendments are designated

(b) are required to be amended for the purposes for which the Scheme is

are to be amended to incorporate the changes necessary to give effect to and to

of the BSC as it is to take effect from the Go-live Date.

duties and functions as Chief Executive and otherwise to support the
implementation and administration of the P&SA;

4.2.3 So far as the Pool Transfer Deed makes provision for the basis on which
BSCCo is to hold any contract (acquired by BSCCo pursuant to the Pool Transfer

agree that:

(a) BSCCo shall be entitled (notwithstanding any such provision) to give
instructions to the contractor and otherwise exercise the rights under the
contract as may be reasonably necessary for or in connection with any of the
matters contemplated by Part F or paragraphs G3, G4 and G5, provided that this
has no material adverse effect

<PAGE>   41

on the implementation of the P&SA and does not constitute a material variation
or waiver of rights and obligations of Pool Members pursuant to such contract;

(b) subject to paragraph

(c), Section C5.1 (excluding references to Section C5.2) of the BSC shall apply
(as if incorporated mutatis mutandis into the Pool Transfer Deed) in relation to

Member pursuant to the Pool Transfer Deed in respect of amounts payable to or
claims made by the contractor under the contract.

4.2.4 The provisions of Section C5.1 (but not Section C5.2) of the BSC shall
apply, mutatis mutandis, in respect of the functions of BSCCo under this

4.3.1 In the event that:

(a) any conflict (including a conflict as to the allocation of BSCCo's
resources) arises between the performance by BSCCo of its duties and functions

and functions under the BSC and under any other provision of the Scheme, and

(b) such conflict cannot be resolved by discussions between BSCCo, the BSC Panel
and the Executive Committee BSCCo may (and if required by the Panel or the

functions by acting in accordance with the Director General's decision.

4.4 ROLE OF PEC AND POOL MEMBERS

4.4.1 It is agreed that with effect from the Scheme Effective Date and until the

particular shall not amend (or agree to amend) the P&SA (including any Agreed
Procedure, Service Line, Supplier Service Line or Code of Practice), or other
document subsisting under the P&SA, in such a way as would (to their knowledge)
conflict with, impede or delay NETA Implementation; provided that nothing done
for the purposes of implementing the P&SA in accordance with its terms, or
complying with any request made by the NETA Programme, shall be a breach of this
paragraph (b);
<PAGE>   43

(c) shall not, without the prior approval of the Director General, make or
procure any change to the Stage 2 Settlement System or Stage 2 Software which
would result in any increase in the extent of the differences (as at the Scheme

(ii) the assets, systems, procedures or software which are necessary in
order to implement Supplier Volume Allocation, except only to the extent to
which emergency circumstances make it necessary to do any such thing (in order
to allow Settlement under the P&SA to continue) before it is possible to seek
the approval of the Director General.

Go-live Date only to the extent provided in paragraph E5.3.

5.2 Recovery of Authorised Pool Expenditure

5.2.1 For the purposes of this paragraph E5.2, "AUTHORISED POOL EXPENDITURE"
means

(a) expenditure in respect of the period commencing 1 st April 2000 (and, so far
as any such expenditure remains outstanding or unrecovered, any earlier period)
authorised by Pool Members pursuant to the P&SA prior to the date of exercise of
the power referred to in the definition of 'Scheme Licence Condition' (and up to
the amount so authorised); and

(b) any further expenditure in respect of that period so authorised by Pool
Members after that date; and whether such expenditure is incurred or funded by
or on behalf of Pool Members (where accruing before the Scheme Effective Date)
or by BSCCo (where accruing after the Scheme Effective Date).

5.2.2 Subject to the provisions of this paragraph E5, Part 4 of Schedule 31
shall continue to apply in accordance with its terms and shall not be affected
by the fact that (in accordance with paragraph E4.2) Authorised Pool Expenditure
is incurred by BSCCo with effect from the Scheme Effective Date.

5.2.3 For the purposes of Part 4 of Schedule 31:

(a) the period from 1 st April 2000 until the day before the Go-live Date shall
be considered to be an Accounting Period; and the provisions of Part 4 of
Schedule 31 (including without limitation provisions as to final determination
of volumes, Contributory Shares, other shares and amounts and the reconciliation
and adjustment in respect of payments by Pool Members) shall apply in respect of
such period on that basis, with any such adjustments as the Executive Committee
or, after the Pool Run-off Date, the BSC Panel may determine to be appropriate
to take account of the fact that such Accounting Period is so varied;

(b) so far as is necessary to give effect to the P&SA (as then in force, and
subject to the Pool Supplement) the period from the Go-live Date to 31 st March
2001 shall be considered to be a further separate Accounting Period.

Scheme Effective Date to the day before the Go-live Date, EPFAL shall in
accordance with Part 4 of Schedule 31:

(a) collect from Pool Members the amounts payable by them pursuant to Part 4 of
Schedule 31 in respect of Authorised Pool Expenditure; and

including amounts n respect of VAT);

<PAGE>   46

and BSCCo shall apply such amounts received by it in or towards meeting, paying
or reimbursing the costs and expenses referred to in paragraph E4.2.1(b) or
otherwise incurred by it as BSC Transitional Costs within paragraph E5.1.3(a).

5.2.5 For the avoidance of doubt BSCCo will hold amounts paid over to it by
EPFAL on its own account and not as trustee for any purposes, and such amounts
shall be released from any trust upon which they are held by EPFAL upon being so
paid over to BSCCo.

5.2.6 Each Party hereby undertakes to BSCCo to pay to EPFAL all amounts payable
by it pursuant to Part 4 of Schedule 31 in respect of Authorised Pool
Expenditure and to indemnify and hold harmless BSCCo in respect of any failure
by such Party to make any payment so required to be made by such Party
(including without limitation any payment required to be made pursuant to Part 4
of Schedule 31 in consequence of the failure of any other Party to make such a
payment).

5.2.7 BSCCo and EPFAL shall co-operate to establish arrangements to ensure
continuity in the collection (before and after the Scheme Effective Date) of
such amounts and for co-ordinating the invoicing and collection of such amounts
with the incurring by BSCCo of Authorised Pool Expenditure.

5.2.8 In this paragraph E5.2 references to EPFAL include any other person which
the Executive Committee may nominate pursuant to paragraph 6.9 or (as the case
may be) 7.8 of Schedule 31, provided that such person has first agreed with
BSCCo to the terms set out in this paragraph E5.2.

5.3 RECOVERY OF FURTHER BSCCO TRANSITIONAL COSTS

5.3.1 It is anticipated that BSCCo will fund BSCCo Transitional Costs, in excess
of the amounts recoverable as Authorised Pool Expenditure, by borrowings.

5.3.2 Notwithstanding paragraph E5.3.1, BSCCo shall be entitled to recover from
Pool Members, and each Pool Member agrees and undertakes to pay to BSCCo its
Contributory Share of, all amounts in respect of BSCCo Transitional Expenditure
(in excess of the amounts recoverable as Authorised Pool Expenditure), to the
extent to which BSCCo does not fund such amounts by borrowings in the
Transitional Period, or is required to pay or repay any amount in respect of
such borrowings and not itself financed by borrowings; (and Annex D-5 of the BSC
provides for the subsequent recovery by Pool Members of amounts so paid).

<PAGE>   47

5.3.3 Paragraph G6.3 sets out the basis on which Section D of the BSC shall
apply for the purposes of giving effect to paragraph E5.3.2.

5.3.4 In this paragraph E5.3, references to Pool Members are to BSC Parties
which are Pool Members.

5.4 GENERAL

5.4.1 Without prejudice to the specific arrangements provided for in this
paragraph E5, BSCCo shall, and other Parties shall cooperate with BSCCo to
enable it to, make and implement arrangements relating to the transition (at the
Go-live Date) from:

(a) the incurring and recovery of BSC Transitional Costs (within paragraph
E5.1.3(a)) under the Scheme and the P&SA, to the incurring and recovery of BSC
Costs under the BSC;

<PAGE>   48

(b) the collection and payment of Supplier charges under the Appendix to
Schedule 26 of the P&SA, to the equivalent arrangements under Annex S-1 of the
BSC; which so far as practicable ensure continuity in and proper accounting for
(and in particular avoid any double counting of or omitting to account for) such
matters, and allocate appropriately costs or amounts which accrue before or
after the Go-live Date but are paid or recovered respectively after or before
that date.

5.4.2 For the purposes of paragraph 1 of Annex D-5 of the BSC, in relation to
the Quarter commencing with the BSC 1998 Start Date (being the first Quarter in
respect of which the provisions of that Annex apply):

(a) the Chargeable 1998 MWh so far as relating to the part of that Quarter which
precedes the Go-live Date shall be determined by reference to the equivalent
quantities under Schedule 22 of the P&SA;

(b) the amount payable by each Supplier shall be determined to include a
reconciliation (in respect of the previous Quarter) as provided in paragraph
1.2.6 of that Annex by reference to what was determined under Schedule 22 of the
P&SA to be payable in respect of that preceding Quarter;

(c) otherwise, the provisions of that Annex shall be given effect so far as
practicable in continuity of the equivalent provisions in Schedule 22 of the
P&SA.

5.4.3 For the avoidance of doubt, nothing in the Scheme shall be construed as
making BSCCo liable to bear, pay, fund or reimburse any costs, expenses or
liability incurred under or pursuant to Schedule 4 or Schedule 15 of the P&SA.

5.4.4 In the Scheme "Contributory Share" has the meaning given to that term in
the P&SA, subject to paragraph E5.2.3(a); and the Contributory Shares of Pool
Members in respect of any period ending after the Go-live Date (for any purpose
of the P&SA or the Scheme which requires such Contributory Shares to be
determined) shall be deemed to be equal to the Contributory Shares determined
under the P&SA in respect of the period ending (in accordance with paragraph
E5.2.3(a)) immediately before the Go-live Date.

6. POOL SUPPLEMENT

Each Party which is a Pool Member and is not a BSC Party undertakes to be bound
by the Pool Supplement (as the same takes effect in accordance with, and as from
time to time modified pursuant to, the Code) as if such Party were a BSC Party.

the Testing and Pre-Production Terms and Conditions.

<PAGE>   51

3.5 The provisions of this paragraph F3 supersede any prior agreement or
arrangement (relating to the subject matter of the Testing and Pre-Production

entitlement to Trading Charges in respect of such Initial Transactions (for the
avoidance of doubt, Initial Trading Data is not Initial Data);

(g) the "TRANSITION DOCUMENT" is the document of that title, designated by the

the matters described in paragraph F4.3) as modified in accordance with
paragraph F4.16, for the purposes of providing transitional arrangements for the
commencement of trading under the BSC;

(h) BSC Systems are "AVAILABLE" when (in each case) the relevant system has been

4.3 The Transition Document sets out:

(a) in relation to certain Initial Data and certain Initial Registrations:

(i) arrangements under which Parties may be required to effect Initial
Registrations or provide Initial Data under procedures or within timescales
which differ from those which would otherwise apply under the BSC;

(ii) in particular, dates (or the basis for determining dates), earlier than the
Go-live Date, by which Parties may be required to effect Initial Registrations
or provide Initial Data;

(iii) arrangements under which, in default of a Party's effecting an Initial
Registration or providing any Initial Data in compliance with the requirements
of the BSC as varied by the Transition Document, such registration may be
effected or data established and recorded on a default basis on behalf of the
Party;

(iv) arrangements for establishing and recording any Initial Data which is not

without limitation) to circumstances applying, things done or decisions made
under the Pooling and Settlement Agreement.

4.4 Each Party shall be bound by the Transition Document and anything done
pursuant to or given effect by virtue of the Transition Document.

4.5 The BSC shall be varied by the Transition Document, so far as the Transition
Document provides for such variation.

4.6 Subject only to the provisions of the Transition Document, it is the
responsibility of each Party to ensure that it has taken all such steps under
and complied with all such requirements of the BSC, as varied by the Transition
Document, as are necessary to secure that the Party is Go-live Compliant,
including effecting all Initial Registrations, providing all Initial Data and
completing all Initial Entry Requirements (including ensuring, where applicable,
that such Party's Party Agents have completed all relevant Initial Entry
Requirements).

4.7 Except where otherwise provided in the Transition Document, the provisions
of the BSC shall apply (in accordance with their terms) as to the steps which
are to be taken and requirements to be satisfied in order for a Party to be
Go-live Compliant.

4.8 It is acknowledged (for the avoidance of doubt) that the consequences under
the BSC of a Party's failing to comply with the requirements referred to in
paragraph F4.6 include the following:

(a) such Party will be in breach of the BSC with effect from the Go-live Date
and will continue to be in breach until such time as he complies with the
requirements of the BSC, and the provisions of Section H3 of the BSC shall apply
accordingly; and

(b) such Party may be unable (in accordance with the BSC) to exercise rights
under the BSC relating to Initial Transactions.

4.9 A Party which is in breach of its obligations as to the provision of Initial
Data or effecting of Initial Registrations shall not be relieved of such breach
by reason of the operation of any

<PAGE>   56

such provision of the Transition Document as is referred to in paragraph
F4.3(a)(iii).

4.10 Each Party accepts responsibility for submitting (in accordance with the
BSC and the Transition Document) all of the data which it is required to submit
in order to be Go-live Compliant and agrees and acknowledges that, if such Party
fails to do so in accordance with the requirements of the BSC and the Transition
Document:

(a) the data which the Party should so submit may be (but the Party is not
entitled to expect that it will be) input to or created as default values in BSC
Systems by BSCCo or any BSC Agent or any person acting in the NETA Programme;

(b) the Party (and only the Party) will be responsible for and bound for the
purposes of the BSC by any data so input or created, and will obliged to review
and validate and where appropriate update or correct the data (and no person
shall have any

<PAGE>   57

responsibility or liability to the Party in respect of the inputting or creation
of data under paragraph (a)).

4.11 Each Party hereby irrevocably and unconditionally agrees and consents to
the doing of anything which is required to be done pursuant to the Transition
Document, including the transfer or other provision to any person or other
release of any data or information (and, for the avoidance of doubt, the
provisions of Section H4.6 of the BSC shall apply to such data and information
as if such data and information had been submitted by such Party under the BSC).

4.12 Each Party agrees that any metering data under the P&SA which relates to
any period (or, in the case of Stage 1 Metering Systems, as defined in the P&SA,
to any period within the 12 months) preceding the Go-live Date shall be provided
or otherwise made available to and may be used and disclosed by BSCCo and BSC
Agents in accordance with the provisions of and for the purposes of the BSC and
the Scheme as if such data had been so provided or made available pursuant to
the BSC.

4.13 It is recognised that, prior to the Go-live Date, Parties may be submitting
data (equivalent to Initial Trading Data) both as part of Pre-Production and for
the purposes of effecting Initial Transactions; therefore, the following rules
shall apply in order to establish whether such data is to be taken into account
for the purposes of determining a Party's liability or entitlement in respect of
Trading Charges under the BSC:

(a) any data (equivalent to Initial Trading Data) submitted by a Party prior to
the date when both of the conditions referred to in paragraph F4.14 have been
met shall not be taken into account for the purposes of determining such Party's
liability or entitlement in respect of Trading Charges under the BSC (whether or
not such data is expressed to apply or be effective in respect of the period on
or after the Go-live Date);

(b) any data (equivalent to Initial Trading Data):

(i) submitted by a Party on or after the date when both of the conditions
referred to in paragraph F4.14 have been met; and

(ii) not withdrawn or modified by such Party (prior to the time when such data
may no longer be withdrawn or modified in accordance with the provisions of the
BSC) shall, subject to the provisions of the BSC and unless BSCCo has notified
such Party

<PAGE>   58

otherwise not less than 5 Business Days before the Go-live Date, be taken into
account for the purposes of determining such Party's liability or entitlement
for Trading Charges under the BSC (to the extent that such data is expressed to
apply or be effective, or would be treated pursuant to provisions of the BSC as
applying or being effective, in respect of the period on or after the Go-live
Date) provided that a Party and BSCCo may agree in writing a later date (being a
date after the date referred to in paragraph (i) above) with effect from which
the provisions of this paragraph F4.13(b) shall apply to such Party.

4.14 The conditions referred to in paragraph F4.13 are that:

(a) the relevant BSC Systems are Available; and

(b) BSCCo has confirmed to the Party that the Party has substantially complied
with the requirements referred to in paragraph F4.6,

<PAGE>   59

and, for the purposes of this paragraph F4.14, the "relevant" BSC Systems are
those BSC Systems required to receive, store and maintain, for the purposes of
Settlement, the Initial Trading Data in question.

4.15 Each Party hereby acknowledges and accepts that:

(a) the BSC Systems will not be Available at the Scheme Effective Date and will
only be Available when BSCCo has notified Parties that such Systems are
Available in accordance with the procedures laid down in the Transition
Document;

(b) notwithstanding that BSCCo has notified Parties that BSC Systems are
Available, such Systems may, after that date, cease to be available on a
temporary basis from time to time prior to the Go-live Date for technical
reasons; and:

(i) BSCCo shall use its reasonable endeavours to notify Parties in advance of
any such period in accordance with the procedures laid down in the
Transition Document;

(ii) for the avoidance of doubt the BSC Systems shall continue to be Available
(for the purposes of this Part F) notwithstanding any such temporary
unavailability.

4.16 The Director General may make modifications, relating to matters of the
kind described in paragraph F4.3 and (following any modification pursuant to
paragraph F5.3) paragraph F5, to the Transition Document in the following
circumstances:

(a) to take account of any matters which emerge as a result of Testing and
Pre-Production;

(b) to take account of any modifications to the Scheme pursuant to the Scheme
Licence Conditions;

(c) to take account of any Transitional BSC Modifications;

(d) to correct any errors or omissions in the Transition Document;

(e) to make such changes as are necessary to ensure that the trading of
electricity under or by reference to the BSC can commence and take place, where
such trading would be prevented or materially hindered for the whole or a
substantial part of the relevant market, or where the operation of the relevant
market for such trading would be materially distorted, without such change; or

(f) to make any other minor consequential changes resulting from any of the
changes referred to in paragraphs (a) to (e).

4.17 Before making any modifications under paragraph F4.16, the Director General
shall consult Parties and, for this purpose:

(a) consultation may be by way of, inter alia , electronic communication; and

<PAGE>   60

(b) the period for responses shall be such as the Director General thinks fit,
taking into account the urgency, importance and complexity of the modification
but shall, in any event, be not less than 2 working days.

<PAGE>   61

4.18 A modification to the Transition Document shall be made upon service by the
Director General to BSCCo of a notice stating that the Transition Document is
modified in the manner set out in such notice, and such modification shall take
effect from the date specified in such notice.

4.19 BSCCo shall forthwith copy any notice referred to in paragraph F4.18 to
each Party which is a BSC Party.

5. PARALLEL RUNNING AND FINAL TRANSITION

5.1 It is anticipated that it will be appropriate for arrangements to be put in
place for parallel running and final transition, for a period before and up to
the Go-live Date, for the purposes of:

(a) further testing of the systems and process involved in the operation of the
Balancing Mechanism and otherwise in the implementation of the arrangements in
the Balancing Codes to be included (pursuant to Part C) in the Grid Code,

(b) managing the transition from operations under the P&SA and the Grid Code as
in force before the Go-live Date to operations under the BSC and the Grid Code
as in force on and after that date.

5.2 For the purposes of this paragraph F5:

(a) parallel running means the taking by NGC and other Parties (in periods
before and up to the Go-live Date) of certain operational steps involved in the
submission of availability declarations (and related offer prices) and
scheduling and despatch for the purposes of SDC1 and SDC2 of the Grid Code and
the P&SA using the new forms of data submission, systems and other processes
designed to support operation of the Balancing Mechanism;

(b) final transition means the operational transition (whether or not as a
continuation of parallel running) from such availability declarations,
scheduling and despatch instructions to the operation of the Balancing
Mechanism;

(c) arrangements for parallel running and final transition may include
arrangements relating to NGC Systems equivalent to those provided for in
paragraphs F4.13 to F4.15.

5.3 The Director General may, after consultation with Parties, modify the
Transition Document to include such arrangements for and matters relating to
parallel running and final transition as appear to him appropriate.

<PAGE>   62

5.4 NGC shall in consultation with other Parties, the Panel and the NETA
Programme:

(a) develop proposals for parallel running and final transition; and

(b) on the basis of such proposals, so far as the proposals require:

(i) any obligations to be placed on any Parties, or

(ii) any variation to be made in respect of the rights and obligations of
Parties in relation to operations under the P&SA and Grid Code as in force
before the Go-live Date

<PAGE>   63

propose to the Director General terms for inclusion in the Transition Document
which sets out such obligations and variations.

3.2 Commencing on the Scheme Effective Date, the differences between or
consistency of the matters referred to in paragraph G3.1 will be identified and
assessed, and such changes in respect of any of those matters made as are
appropriate (in the case of the BSC, as approved by the Director General
pursuant to paragraph G5 and, in the case of BSC Subsidiary Documents, as
approved by the BSC Panel pursuant to the relevant provisions of the BSC but
having regard to the principle set out in paragraph G4.3) for the purposes of
removing such differences or ensuring such consistency.

<PAGE>   70

to the Director General additions and, if applicable, changes to the BSC and BSC
Subsidiary Documents in respect of each the following issues (separately):

(a) arrangements, on an enduring basis, to address the possibility of
emergencies (for example, significant system failures, Fuel Security Periods,
civil emergencies and similar events) arising which affect the operation of the
Balancing Mechanism and/or the Settlement process, including (without
limitation) provisions relating to the identification and consequences (for BSC
Parties) of such emergencies, with a view to including appropriate contingency
arrangements in the BSC prior to the Go-live Date;

(b) arrangements to apply in the situation where a Supplier fails or becomes
insolvent, including arrangements for the replacement of that Supplier for the
purposes of the BSC and arrangements, where applicable, for the allocation of

ancillary matters; and

(d) the adoption of arrangements (or provision for the establishment of
arrangements) similar, as far as appropriate and applicable, to those contained
in schedule 23 of the P&SA, taking account of any structural, governance and
other relevant differences between the P&SA and the BSC.

3.6 For the purposes of paragraph G3.5 and in relation to the matters referred
to in that paragraph, BSCCo and the NETA Programme shall as soon as reasonably
practicable after the Scheme Effective Date:

developing and evaluating proposals for additions and/or changes to the BSC and
for

<PAGE>   71

undertaking the further steps set out in this paragraph G3.6;

parties during the consultation exercise and BSCCo's and the NETA Programme's
combined recommendations as to the most appropriate option(s) which the Director
General might direct as a Transitional BSC Modification.

3.7 Without prejudice to the responsibilities assigned to BSCCo and the NETA
Programme in this paragraph G3, it is acknowledged that it may not be necessary
to complete the implementation of the matters envisaged by this paragraph G3
during the Transitional Period,

<PAGE>   72

and nothing in the Scheme shall prevent the Go-live Date from being determined
as a date on which such implementation is not complete.

4. UPDATING OF BSC SUBSIDIARY DOCUMENTS

4.1 The BSC Subsidiary Documents in force as at the Scheme Effective Date are
listed in Annex 2 (with reference to versions of those documents prepared and
identified as such by the NETA Programme or the office of the Pool Chief
Executive not later than the Scheme Effective Date).

revision (in addition to what is required pursuant to paragraph G3) in the
Transitional Period:

(a) generally to ensure that they are consistent with, and comply with the
requirements (as to BSC Subsidiary Documents or classes thereof generally, and
as to particular such documents) of, the BSC (after taking account of paragraph
G3);

(b) in particular, where they are based on equivalent documents subsisting under
the P&SA, to ensure that such documents have been properly adapted to reflect
the provisions of (including defined terms in) the BSC.

4.3 The BSC Panel and BSCCo shall act in co-operation with the Implementation
Director and the NETA Programme to ensure that the BSC Subsidiary Documents are
so reviewed and revised, in timescales and in accordance with procedures which
are appropriate having regard to the purposes and requirements of the Scheme.

5. TRANSITIONAL BSC MODIFICATIONS

5.1 The provisions of Section F of the BSC as they relate to modification of the
BSC shall not apply for the duration of the Transitional Period (provided that,
for the avoidance of doubt, nothing in the Scheme shall prevent the BSC Panel
and/or BSCCo taking such steps as they consider appropriate to establish working
arrangements for the conduct of the Modification Procedures contained in Section
F of the BSC, which are intended to take effect from the Go-live Date).

5.2 During the Transitional Period, the BSC may be modified pursuant to
Condition 7C(7) of the Transmission Licence in the circumstances set out in
paragraph G5.3.

5.3 The circumstances referred to in paragraph G5.2 are:

as envisaged fby the Pool Supplement (including arrangements relating to the
contracts and services required to support the Pool Supplement);

(g) to make such changes as are necessary to ensure that the trading of
electricity under or by reference to the BSC can commence and take place, where
such trading would be prevented or materially hindered for the whole or a
substantial part of the relevant market, or where the operation of the relevant
market for such trading would be materially distorted, without such change; or

(h) to make any other minor consequential changes resulting from any of the
changes referred to in paragraphs (a) to (g).

5.4 Where NGC is directed by the Director General during the Transitional Period
to make a modification to the BSC pursuant to the Transmission Licence, NGC
shall serve on BSCCo a notice of such modification signed by NGC, and BSCCo
shall forthwith:

(a) copy such notice to each BSC Party and each BSC Agent;

(b) place a copy of such notice on the BSC Website.

5.5 A modification made in accordance with paragraph G5.4 shall take effect from
the time and date (if any) specified in such notice (in accordance with the
direction of the Director General pursuant to the Transmission Licence) and, in
the absence of any such time or date, from 0000 hours on the day next following
the date of service on BSCCo of a notice referred to in paragraph G5.4.

6. TRANSITIONAL APPLICATION OF THE BSC

6.1 Subject to the provisions of the Scheme, the BSC shall apply in relation to
the Transitional Period (but without prejudice to Section H2.3 of the BSC).

6.2 Without prejudice to the generality of paragraph G6.1:

(a) Sections B and C of the BSC shall apply by reference to the duties,
functions and responsibilities of the BSC Panel and BSCCo which are to be
discharged in the Transitional Period, except that Section C5.2 shall not apply;

(b) for the purposes of Section C6 of the BSC the Transitional Period shall be
considered to be a BSC Year and there shall be a separate Business Strategy and
Annual Budget for such period, but the provisions of Sections C6.3.1 and C6.4.1
shall not apply in relation thereto and instead such Business Strategy and
Annual Budget shall be

<PAGE>   75

established according to such procedures as shall have been established by the
NETA Programme and/or as BSCCo shall determine with the approval of the BSC
Panel;

(c) Section D of the BSC shall be varied and shall apply for the purposes of
paragraph E5.3.2 as provided in paragraphs G6.3 and G6.4.

6.3 Section D of the BSC (including without limitation Section D6 and in
particular Section D6.6) shall apply, mutatis mutandis, in relation to the
Transitional Period on the following basis:

(a) amounts incurred by BSCCo in any month in respect of BSCCo Transitional
Expenditure (in excess of amounts recoverable as Authorised Pool Expenditure,
and

<PAGE>   76

other than amounts funded by borrowings) shall be treated as being Monthly Net
Main Costs (for the purposes of Section D);

(b) references to Trading Parties in Section D shall be construed as references
to Pool Members (as construed in accordance with paragraph G6.4(a));

7. FURTHER ASSURANCE

7.1 It is recognised that it may be necessary to take urgent action in certain
circumstances in the period following the Go-live Date, while the new
electricity trading arrangements are in their early stages, in order to address
problems which may emerge in the implementation and operation of those
arrangements.

<PAGE>   78

7.2 At any time during the period of 12 months following the Go-live Date, the
Director General may, in the circumstances set out in paragraph G7.3, require
the BSC Panel (by notice in writing to the Panel Secretary):

(i) what modification(s) to the BSC would prevent the substantial disruption
referred to in paragraph G7.3 from continuing or recurring or would mitigate
such substantial disruption; and

(ii) what modification proposal to make which would best achieve that purpose
and which would, in the BSC Panel's opinion, better facilitate achievement of
the Applicable BSC Objective(s); and

(b) immediately upon completion of such consideration, either:

(i) to propose the modification which the BSC Panel considers would best achieve
that purpose; or

(ii) to advise the Director General in writing that, in the BSC Panel's opinion,
no urgent modification is feasible (for technical or other reasons) to prevent
or mitigate such substantial disruption, with a brief summary of the BSC
Panel's reasons for such conclusion.

7.3 The circumstances referred to in paragraph G7.2 are that, in the Director
General's opinion:

(a) there is substantial disruption (or substantial disruption has occurred and
is likely to recur) to the implementation and/or operation of the new
electricity trading arrangements (resulting from the exercise by the Secretary
of State on 7 August 2000 of the powers conferred on him under section 15A of
the Act) which result from matters inherent in the BSC; and

(b) urgent action is necessary to prevent such disruption from continuing or
recurring or to mitigate such disruption.

7.4 The BSC Panel shall comply with any notice issued by the Director General
pursuant to paragraph G7.2 and shall do so with all due speed, having regard to
the urgency of the matters in question and consistent with the timescales, if
any, specified by the Director General in such notice.

7.5 A modification proposal made by the BSC Panel pursuant to the provisions of
paragraph G7.2:

(a) shall be made in writing in such form as the BSC Panel thinks fit;

(b) shall be treated for the purposes of Section F of the BSC as an Urgent
Modification

<PAGE>   79

Proposal (and the provisions of paragraph G7.6 shall apply accordingly); and

(c) shall be copied to each BSC Party by the Panel Secretary as soon as
reasonably practicable after the making of such proposal and any such proposal
shall be treated as having been made under and in accordance with, and having
otherwise complied with, the requirements of Section F2.1 of the BSC.

<PAGE>   80

7.6 Where the BSC Panel makes a modification proposal pursuant to the provisions
of paragraph G7.2, the Panel Chairman shall forthwith consult with the Director
General as to the procedure and timetable which should apply in respect of such
proposal and the BSC Panel shall comply with any instruction of the Director
General issued in respect of such matters.

7.7 Without prejudice to paragraph G7.6, the BSC Panel shall use reasonable
endeavours to seek the views of BSC Parties and interested third parties on the
matters to be considered by the BSC Panel under paragraph G7.2(a) where
reasonably practicable within the timescales required by the Director General
for completion of such steps and having regard to the urgency of the matters in
question.

7.8 BSCCo shall:

(a) provide such support and assistance as the BSC Panel may require in order to
fulfil its duties under this paragraph G7;

(b) implement any modification proposal made under this paragraph G7 and
approved by the Director General in accordance with the Implementation Date
specified by the Director General in such approval.

7.9 For the purposes of Section F2.9.7 of the BSC, the BSC Panel shall conduct a
review of each modification made pursuant to the provisions of this paragraph G7
in accordance with the provisions of Section F2.9.7 within 3 months of each such
modification.

8. INITIAL BSC YEAR

8.1 For the purposes of the BSC, in relation to the initial BSC Year from the
Go-live Date until the next following 31 st March:

(a) where anything (which is required to be done under the BSC, in relation to a
BSC Year, before the start of such year) would thereby be required to be done
(in relation to the initial BSC Year) before the Scheme Effective Date, such
thing shall be done as soon as reasonably practicable after the Scheme Effective
Date;

(b) where any other question arises as to how any provision of the BSC (applying
by reference to a BSC Year) is to apply in relation to the initial BSC Year, the
BSC Panel may decide such question after consultation with Parties and the
Director General.

Notes:

1. Documents marked with an asterisk have been developed by and are (before the
Scheme Effective Date) available to BSC Parties from the Pool Chief Executive's
Office. Other documents are available from the NETA Programme.

2. These initial versions of the BSC Subsidiary Documents are subject to review
and revision before the Go-live Date as described in paragraph G4 of the NETA
Implementation Scheme.

3. Various COP versions/Issues will apply to Metering Equipment depending when
the Equipment was Installed, Registered and/or what Dispensations are
applicable. New BSC versions of the current COPs will be issued with an Issue
number of v1.0, but with no technical changes to the COPs. (It should be noted
that the COPs are distributed World wide and are changed as little as possible,
since meter manufacturers have long lead times when developing or changing
products.).

4. References to the Logica Contract are to the agreement between Logica UK
Limited and BSCC Limited (now Elexon Limited) entitled NETA Programme Services
Agreement and dated 12 May 2000. References to the EPFAL Services Agreement are
