Item 1.       BUSINESS

       Solely for the convenience of the reader, certain pounds sterling amounts
have been translated into US dollars at the Noon Buying Rate on March 31, 1998
of $1.6765 = (pound)1.00; see Note 1 in the "Notes to the Financial Statements".

General

       The Company is a wholly-owned subsidiary of Holdings. Throughout the
period under review, 75% of Holdings was owned indirectly by Southern and 25%
was owned indirectly by PP&L Resources. On June 18, 1998, Southern sold a
further share of its ownership in Holdings to PP&L Resources; see Note 13 in the
"Notes to the Consolidated Financial Statements". The Company was incorporated
as a public limited company under the laws of England and Wales in June 1995 as
a vehicle for the acquisition of SWEB, one of the 12 RECs in England and Wales
licensed to distribute, supply and, to a limited extent, generate electricity.
In September 1995, the Company gained effective control of SWEB, and
subsequently replaced SWEB's board of directors and certain senior managers with
officers and employees of companies from within the Southern Company system. The
Company's sole investment and only significant asset is the entire share capital
of SWEB, which is headquartered in Bristol, England. At March 31, 1998 the
Company had consolidated assets of (pound)1.728 billion ($2.897 billion).

       SWEB's two main business lines are the distribution of electricity and
supply of electricity to approximately 1.3 million customers in its Authorized
Area in southwest England. The distribution business and the supply business are
distinct business segments and produced operating income of (pound)106 million
($178 million) and (pound)22 million ($37 million), respectively, in fiscal year
1998, representing substantially all of the Company's consolidated operating
income in that fiscal year.

       SWEB's Authorized Area covers approximately 5,560 square miles extending
from Bristol and Bath in the northeast, 188 miles southwest along the peninsula
to Land's End and 28 miles beyond to the Isles of Scilly, and has a resident
population of approximately 2.8 million. The southwest of England, of which the
Authorized Area forms the greater part, has benefitted from economic growth (as
measured by Gross Domestic Product) which on average has exceeded the UK rate
over the long term and on average was broadly similar to it from 1992 through
1997. The area has also benefitted from an average unemployment rate during
calendar year 1997 of approximately 4.4% which was below the UK average of 5.6%
according to a 1998 study by Cambridge Econometrics. The largest cities and
towns in SWEB's Authorized Area are Bath, Bristol, Exeter, Plymouth and Taunton.
Business activity is generally concentrated in the population centers around
Bristol, Bath and Plymouth. The Bristol and Bath area is served by the M4 and M5
motorways, a strong rail network including a link between Bristol and London,
and a commercial port at Avonmouth.

       The Company and SWEB have undertaken to make SWEB a more focused and
competitive company concentrating on the main electricity businesses of
distribution and supply. Several businesses not related to distribution and
supply have been sold, and the remaining ancillary businesses have been
redirected to focus on support for the main electricity businesses.

Change of Government in the UK

       The first budget of the newly elected Labour government had a significant
impact on the profitability of the Company in the fiscal year 1998. The Labour
Party's election manifesto included the commitment to introduce "a one-off
windfall levy on the excess profits of the privatized utilities", and on July 2,
1997 the government presented its first budget which included such a levy. Based
upon the legislation, SWEB estimated its liability to be approximately (pound)90
million ($151 million). The levy is payable in two equal installments. The first
installment was paid on December 1, 1997 and the second will be paid on or
before December 1, 1998. The legislation also reduced the UK corporation tax
rate from 33% to 31% with effect from April 1, 1997. Such a decrease resulted in
an accounting credit reducing SWEB's provision for deferred income taxes by
approximately (pound)22 million ($37 million). Both items were included in the
second quarter's earnings.
                                   
       On March 17, 1998 the government announced its second budget proposing a
further reduction in the UK corporation tax rate to 30%. This will become
effective from April 6, 1999, but only after receiving Royal assent which is

                                      I-1


<PAGE>

expected to be in August 1998. From that date, SWEB should be able to further
reduce its provision for deferred income taxes by approximately (pound)11
million ($18 million).

Overview of the Electric Utility Industry in Great Britain

       In 1990, the electric utility industry in Great Britain was privatized,
and SWEB was created along with the other 11 RECs in England and Wales. In
connection with the privatization, distribution assets in England and Wales,
previously owned indirectly by Her Majesty's Government, were allocated among
the RECs, licensing requirements were established for the RECs and price
controls were implemented in the areas of distribution and supply. In England
and Wales, generation assets (other than nuclear facilities) were allocated to
two generating companies, and the high voltage transmission assets were
allocated to NGG.

       The high voltage transmission system in England and Wales, which is
generally referred to as the "national grid", carries the generated electricity
in bulk from the power stations to the regional and local distribution systems.
This transmission system is owned and operated by NGG.

       Distributors transfer electricity over their networks, generally at lower
voltage than the national grid, from supply points on the national grid to final
consumers. The distribution systems in England and Wales are owned by the 12
RECs. Virtually all customers in England and Wales are connected to the
distribution system of the RECs and have no choice as to the distribution system
from which they receive their electricity. Distribution prices charged by the
RECs are regulated by the Distribution Price Control Formula.

       Suppliers sell electricity to end users. Each REC is required to have a
PES license which authorizes it to supply electricity to any customers within
its Authorized Area. Electricity customers fall into two categories, Regulated
Supply Customers (largely domestic and small commercial) and Unregulated Supply
Customers. Prices for supply of electricity to Regulated Supply Customers were
regulated by the Supply Price Control Formula until March 31, 1998. The
exclusive right to supply Regulated Supply Customers was scheduled to be phased
out over a six-month period commencing April 1, 1998, after which all supply
customers would have the ability to choose their electricity supplier. An
announcement by the Regulator on October 16, 1997 stated that the phasing out of
the exclusive right to supply Regulated Supply Customers should be phased in
from September 1998. Each REC has an authorized start date for competition to
commence in its Authorized Area, and SWEB's is towards the end of calendar year
1998. Once a REC's Authorized Area is open to competition, then it can compete
in the Authorized Area of other RECs where competition has commenced, and vice
versa. From April 1, 1998, prices which a REC may charge to Regulated Supply
Customers within its Authorized Area are subject to a Price Cap determined by
the Regulator. Unregulated Supply Customers (as defined prior to April 1, 1998)
may already be supplied by any company which has obtained the required license.
Such suppliers, including SWEB, compete for business nationally and at prices
determined by competitive bids or negotiation.

       At the time of privatization, the Pool was established for bulk trading
of electricity in England and Wales between generators and suppliers. The Pool
reflects two principal characteristics of the physical generation and supply of
electricity from a particular generator to a particular supplier. First, it is
not possible to trace electricity from a particular generator to a particular
supplier. Second, it is not practicable to store electricity in significant
quantities, creating the need for a constant matching of supply and demand.
Subject to certain exceptions, all electricity generated in England and Wales
must be sold and purchased through the Pool. All licensed generators and
suppliers must become signatories to a Pooling and Settlement Agreement, which
governs the constitution and operation of the Pool and the calculation of
payments due to and from generators and suppliers. Prices for electricity are
set by the Pool daily for each half hour of the following day based on the bids
of the generators and a complex set of calculations matching supply and demand
and taking account of system stability, security and other costs.
  
SWEB's Main Businesses

Distribution Business

       SWEB's distribution business is the ownership, management and operation
of the electricity distribution network within SWEB's Authorized Area. The
primary activity of the distribution business is the receipt of electricity from
the national grid transmission system and its distribution to end users of
electricity that are connected to SWEB's power lines. Virtually all electricity
supplied (whether by SWEB's independent supply business or by other suppliers)
to consumers in SWEB's Authorized Area is transported through its distribution


                                    I-2

<PAGE>


network, thus providing SWEB with distribution volume that is stable from year
to year. As a holder of a PES license, SWEB is subject to a regulatory framework
that provides economic incentives to increase the number of units of electricity
distributed and to operate in a more cost-efficient manner.

       SWEB's distribution business has grown in both its customer base and in
the number of units distributed, primarily reflecting economic growth in the
southwest of England. At March 31, 1998 SWEB had experienced a 5-year compound
annual growth rate of 0.9% in customers and 1.9% in units distributed.

Strategy

       Since being acquired by the Company, SWEB has reviewed and refined its
distribution strategy and has established key goals of cost savings and improved
customer service.

       Staff reductions play a key role in cost savings. Since acquisition, SWEB
has implemented a plan of voluntary and other staff reductions, mainly in the
distribution business. By March 31, 1998 staff numbers had been reduced by 743
(22%). Part of these reductions were made possible due to new work practices
which SWEB has developed with the cooperation of SWEB's unions. Team
restructuring in the engineering group and the establishment of multi-skilled
independent field teams have been achieved. In addition, management
restructuring has produced a flatter organizational structure by reducing
management levels from seven to three.

       Improvements in customer service in the distribution business are part of
SWEB's strategy and are expected to enable SWEB to meet or exceed the
performance criteria established by the Regulator who is responsible for setting
the performance standards of the RECs. SWEB believes that achieving these goals
is important both for improving customer satisfaction and for maintaining good
relations with the Regulator. Improvements in customer service are being
pursued, in part, through improvements in system performance, measured primarily
in terms of customer minutes lost, number of outages and the time necessary to
restore customers after an outage. To that end, several initiatives are being
pursued including:

  *  refurbishment of 11kv aluminum overhead lines;

  *  eliminating a backlog of tree-trimming near distribution lines;

  *  introduction of rubber glove working techniques, allowing work to take
     place on the network without disrupting supplies to customers;

  *  implementing a program of network improvements that creates more dual
     routing;

  *  reordering the priorities of SWEB's capital expenditure program to focus
     on improving system reliability;

  *  implementation of a computerized telecontrol system, allowing the move to
     one centralized Control Room, providing a speedier, more accurate and
     reliable service to customers;

   * continuous process improvement and training at our call center supported
     by new computerized information systems; and,

   * monthly measurement of customer satisfaction through individual telephone
     surveys.

Customers

         Most of SWEB's distribution customers are Regulated Supply Customers.
This customer group consists predominantly of residential and small commercial
consumers which provides SWEB a stable customer base. SWEB's fastest growing
category of distribution customers, in terms of units distributed and revenues,
is commercial and small industrial customers. Commercial activity of SWEB's
customers is mostly service based and includes financial services, electronics
and technology-related businesses. SWEB also distributes electricity to
industrial concerns in its Authorized Area. The principal activities of SWEB's


                                     I-3
<PAGE>

largest distribution customers include china clay extraction, ship repair,
fertilizer production, aerospace, defense engineering, cement and paper
manufacturing and water supply. SWEB's 20 largest distribution customers in its
Authorized Area accounted for 11% of total electricity distributed by SWEB in
fiscal year 1998 in terms of units distributed, with no single customer
exceeding 3% of total electricity distributed.

         The following table sets out details of SWEB's distribution customers,
units distributed and distribution revenues.

Distribution Facilities

       Electricity is transported across the national grid transmission system
at 400kv or 275kv to ten grid supply points connected to SWEB's distribution
network, where it is transformed to 132kv and enters SWEB's distribution system.
Two of these grid supply points are situated in neighboring RECs' Authorized
Areas. Substantially all electricity which enters SWEB's system is received at
these ten grid supply points.

       At March 31, 1998, SWEB's electricity distribution network (excluding
service connections to consumers) included overhead lines and underground cables
at the operating voltage levels indicated in the table below:

       Operation and control of SWEB's distribution system is continuously
monitored and coordinated from a control center located in Exeter. Electricity
is received by customers at various voltages depending upon their requirements.
At March 31, 1998, SWEB's distribution system was connected to over 1.3 million
customers.

Supply Business

       SWEB's supply business is selling electricity to end users, purchasing
such electricity, primarily from the Pool, and arranging for its distribution to
those end users. SWEB's supply business is comprised predominantly of supplying
Regulated Supply Customers (largely domestic and small commercial). In fiscal
year 1998, these customers accounted for approximately 73% of all units of
electricity supplied by SWEB. Prices for these customers were regulated, and
SWEB's costs of purchasing, hedging, and delivering electricity were collected
from them on an actual cost basis.

       The exclusive right to supply Regulated Supply Customers (as defined
prior to April 1, 1998) was scheduled to be phased out over a six-month period
commencing April 1, 1998, after which all supply customers would have the
ability to choose their electricity supplier. An announcement by the Regulator
on October 16, 1997 stated that the phasing out of the exclusive right to supply
Regulated Supply Customers should be phased in from September 1998. Each REC has
an authorized start date for competition to commence in its Authorized Area, and
SWEB's is towards the end of calendar year 1998. Once a REC's Authorized Area is
open to competition, then it can compete in the Authorized Area of other RECs
where competition has commenced, and vice versa. SWEB intends to maintain a
significant share of these customers by providing superior service and
competitive pricing. The Regulator has also proposed a penalty on all RECs,
including SWEB, related to the delay in opening the remainder of the supply
market to competition beyond the April 1, 1998 deadline; any penalty imposed on
SWEB is not expected to have a material impact on earnings. The supply tariffs
for Regulated Supply Customers in fiscal years 1999 and 2000 represent maximum
price restraints ("Price Cap") intended to protect such customers.

       The market to supply Unregulated Supply Customers (as defined prior to
April 1, 1998) is fully competitive, principally with other RECs and the major
generators. Unregulated Supply Customers are typically supplied through
individual contracts with a duration of from one to two years with competitively
bid or negotiated prices.

Strategy

       Since its acquisition by the Company, SWEB has completed a review of the
supply market, established new goals for its supply business and adopted new
strategies for achieving those goals. The key goals established are the
retention of its current Regulated Supply Customers as supply customers after
the opening of the market, and a profitable increase in SWEB's share of
electricity supplied to Unregulated Supply Customers both inside and outside
SWEB's Authorized Area.

       SWEB's strategy for retaining its Regulated Supply Customers is to build
customer loyalty and to offer competitive prices. SWEB seeks to build customer
loyalty by providing superior, responsive service in dealing with billing and
other matters and providing other service enhancements.

       Initiatives in relation to the Regulated Supply Customers include:

  *  a single-number, local rate, telephone service call center (which has been
     in place since April 1996);

  *  improvements and enhancements to the billing and customer service system
     which will enable employees at the call center to act on or resolve
     customer billing and account inquiries on line during their calls (which
     has already begun and should be fully operational in 1998); and

 *   increasing meter reads to reduce estimated readings. In the UK, most
     meters are located within structures and meter readers are required to
     obtain access from occupants in order to read meters.

                                      I-5

<PAGE>

       SWEB's strategy for sales to Regulated Supply Customers outside its
Authorized Area is to respond to any request received for a quotation, and to
actively pursue high margin/low acquisition cost customers. SWEB's strategy for
Unregulated Supply Customers both inside and outside its Authorized Area is to
offer competitive pricing and, with respect to its Unregulated Supply Customers
inside its Authorized Area, to build customer loyalty through the measures
described above. Additional initiatives to support growth in market share in
both the Supply Customer markets include:

  *   the expanded use of account managers;

  *   increasing the number of proposals and bids made to customers, potential
      customers, brokers and agents;

  *   development of an integrated system for contract customer sales,
      electronic registration and marketing with full customer life-cycle
      management and tracking facilities (which was brought into service during
      February 1997); and

  *   further enhancement of a competitive price setting system used to
      determine appropriate contract supply prices;

Regulated Supply Market

       Under the terms of its PES license, SWEB currently holds the right to
supply approximately 1.3 million Regulated Supply Customers within its
Authorized Area. See "Business-General". During fiscal year 1998, sales to
Regulated Supply Customers (as defined prior to April 1, 1998) represented 73%
of total units supplied by SWEB and produced 81% of SWEB's total supply
revenues.

       As discussed above, the exclusive right to supply Regulated Supply
Customers is scheduled to be phased out and SWEB intends to maintain a
significant share of these customers by providing superior customer service and
competitive pricing. In fiscal year 1998, SWEB met or exceeded the Regulator's
standards of performance targets for all of the services measured by the
Regulator. SWEB has moved from worst to best in a national ranking of RECs in
respect of customer complaints received.

Unregulated Supply Market

       In addition to competing for Unregulated Supply Customers in its
Authorized Area, SWEB holds the required license to compete with RECs and other
suppliers to provide electricity to Unregulated Supply Customers outside its
Authorized Area. At the end of fiscal year 1998, SWEB had approximately 1,770
Unregulated Supply Customers, consisting primarily of large commercial and
industrial accounts. Revenue from Unregulated Supply Customers during fiscal
year 1998 accounted for 19% of total supply revenues.

SWEB's Other Business Activities

       SWEB also has ancillary business activities that support its main
electricity distribution and supply businesses, including electricity
generation. SWEB owns generating assets with 16 MW of capacity used to back up
the distribution network as well as minority investments in windfarms, a
landfill gas generation project, and a 7.69% interest in Teesside Power Limited,
owner of a 1,875 MW combined cycle plant. SWEB derives small amounts of revenue
from the lease of fibers within the fiber optic cables carried on its
distribution network, and also markets and develops property no longer used in
the main electricity businesses.

Risk Management

       SWEB's distribution business does not involve the purchase and sale of
electricity, and therefore SWEB's risk management efforts are focused on the
supply business which is exposed to Pool price volatility. SWEB uses CFDs to
hedge against Pool price volatility. CFDs are contracts predominantly between
generators and suppliers which fix the price of electricity for a contracted
quantity of electricity over a specific time period. Differences between the
actual price set by the Pool and the agreed prices give rise to difference
payments between the parties to the particular CFD. At the present time, SWEB's
forecast total demand for fiscal year 1999 is substantially hedged through
various types of agreements including CFDs.

                                      I-6

<PAGE>



       The most common contracts for supply to Unregulated Supply Customers are
for a twelve-month term and contain fixed rates. SWEB is exposed to two
principal risks associated with such contracts: load shape risk (the risk
associated with a shift in the customer's usage pattern, including absolute
amounts demanded and timing of amounts demanded) and purchasing price risk (the
cost of purchased electricity relative to the price received from the supply
customer). SWEB employs risk management methods to maximize its return
consistent with an acceptable level of risk. SWEB manages load shape risk by
setting individual customer sales prices based on their expected load shape and
including an additional premium to cover the risk of load shape variation.
Variable volume CFDs are also used when available at a competitive price. SWEB
hedges purchasing price risk by employing a variety of risk management tools,
including management of its supply contract portfolio, hedging contracts and
other means which mitigate risk of future Pool price volatility.

       SWEB's ability to manage its purchasing price risk depends, in part, on
the future availability of properly priced risk management mechanisms such as
CFDs. SWEB intends to purchase cover at competitive prices and constantly
evaluates market conditions. No assurance can be given that an adequate,
transparent market for such products will in fact be available and thus that
contracts will be available at competitive prices.

       SWEB constantly evaluates whether owning its own source of generation or
contracting for such source or sources is the most appropriate method for
managing purchase price risk, but no assurance can be given that such methods
would be available to, or economically appropriate for, SWEB.

       The Company and SWEB utilize certain financial derivative contracts for
the sole purpose of hedging business exposure in connection with fluctuations in
interest rates and currency rates. Interest rate swaps are used to assure the
stability of future interest charges by effectively converting a portion of
outstanding variable-rate debt into fixed rates. In addition, the US dollar
liabilities associated with certain of the Company's and SWEB's debt are
converted into pounds sterling by entering into foreign currency hedging
contracts.

UK Environmental Regulation

       SWEB's businesses are subject to numerous regulatory requirements with
respect to the protection of the environment. The Electricity Act obligates the
President of the Board of Trade and Secretary of State for Trade and Industry to
take into account the effect of electricity generation, transmission and supply
activities upon the physical environment in approving applications for the
construction of generating facilities and the location of overhead power lines.
The Electricity Act requires SWEB to have regard to the desirability of
preserving natural beauty and the conservation of natural and man-made features
of particular interest when it formulates proposals for development in
connection with certain of its activities. SWEB mitigates the effects its
proposals have on natural and man-made features and is required to carry out an
environmental assessment when it intends to lay cables, construct overhead lines
or carry out any other development in connection with its licensed activities.
SWEB also has produced an Environmental Policy Statement which sets out the
manner in which it intends to comply with its obligations under the Electricity
Act.

       The Environmental Protection Act 1990 addresses waste management issues
and imposes certain obligations and duties on companies which handle and dispose
of waste. Some of SWEB's distribution activities produce waste, but SWEB
believes that it is in compliance with applicable standards in such regard.

       Possible adverse health effects of EMFs from various sources, including
transmission and distribution lines, have been the subject of a number of
studies and increasing public discussion. The scientific research is currently
inconclusive as to whether EMFs may cause adverse health effects. The only UK
standards for exposure to power frequency EMFs are those promulgated by the
National Radiological Protection Board and relate to the levels above which
non-reversible physiological effects may be observed. SWEB fully complies with
these standards. However, there is the possibility that the introduction and
passage of legislation and change of regulatory standards would require measures
to mitigate EMFs, with resulting increases in capital and operating costs. In
addition, the potential exists for public liability with respect to lawsuits
brought by plaintiffs claiming damages for adverse health effects caused by
EMFs.

       SWEB believes that it has taken and continues to take measures to comply
with the applicable laws and governmental regulations for the protection of the
environment. There are no material legal or administrative proceedings pending
against SWEB or the Company with respect to any environmental matter.

Employee Relations

       At March 31, 1998, SWEB had 2,597 employees (2,523 full time equivalent)
and the Company had no employees. Of SWEB's employees, 96% are represented by
labor unions. All SWEB employees who are not party to a personal employment
contract are subject to one of two collective bargaining agreements. One is
called The Electricity Business Agreement, which covered 2,381 employees at
March 31, 1998 (2,307 full time equivalent); it may be amended by agreement
between SWEB and the unions and is terminable with 12 months notice by either
side. The other is called the SWEB Data Collection Services Agreement, which
covered 104 employees at March 31, 1998 (103 full time equivalent); it may be
amended by agreement between SWEB and the unions and is terminable by written
notice (with no period specified) by either side. SWEB believes that its
relations with its employees are favorable. Legal proceedings concerning the
Electricity Supply Pension Scheme involving a company other than SWEB were
taken. These proceedings may affect SWEB in the future.  See "Item 3 - Legal
Proceedings".


Item 2.       PROPERTIES

       SWEB has both network and non-network land and buildings.

Network Land and Buildings

       At March 31, 1998 SWEB had freehold and leasehold interests in
approximately 12,000 network properties, comprising principally substation
sites. The recorded cost of total network land and buildings at March 31, 1998
was (pound)72 million ($121 million).

Non-Network Land and Buildings

       At March 31, 1998 SWEB had freehold and leasehold interests in
non-network properties comprising chiefly offices, former retail outlets,
depots, warehouses and workshops and including the freehold of its principal
executive offices in Bristol. The recorded cost of total non-network land and
buildings at March 31, 1998 was (pound)37 million ($62 million).

       The number of properties in each category is:

Item 3.       LEGAL PROCEEDINGS

       The Company and SWEB are routinely party to legal proceedings arising in
the ordinary course of business which are not material, either individually or
in the aggregate. The Company is not a party to any material legal proceedings
nor is it currently aware of any threatened material legal proceedings, except
as described below.

       The Pensions Ombudsman (a UK statutorily appointed independent
arbitrator) had issued a determination in favor of complaints made by members of
the Electricity Supply Pension Scheme ("ESPS") relating to another employer's
use of ESPS surplus to offset the employer's costs of providing early pensions
on redundancies and certain other items. Under that determination the Pensions
Ombudsman directed the employer to pay into ESPS the amount of that use of the
surplus plus interest. The determination was challenged in the High Court by the
employer, and the High Court upheld the employer's appeal in a judgment
delivered on June 10, 1997. The High Court also granted the complainants leave
to appeal to a higher court. No date has yet been set for any hearing in the
   
                                   I-8

<PAGE>

Appeal Court. If the complainants' appeal is successful, either at the Appeal
Court or on a subsequent appeal to the House of Lords, it will have an adverse
effect on SWEB. Unless the High Court decision is reversed, this case should not
impact SWEB significantly; however it is not practical to make an estimate of
the exposure at the present time.

Item 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS
           AND FINANCIAL CONDITION

       The following discussion should be read in conjunction with the
consolidated financial statements and the notes thereto. The consolidated
financial statements discussed in this Section are presented in accordance with
US GAAP. Solely for the convenience of the reader, certain pounds sterling
amounts have been translated into US dollars at the Noon Buying Rate on March
31, 1998 of $1.6765 = (pound)1.00; see Note 1 in the "Notes to the Financial
Statements".

INTRODUCTION

Background

       The Company was incorporated as a public limited company under the laws
of England and Wales in June 1995, as a vehicle for the acquisition of SWEB. In
September 1995, the Company gained effective control of SWEB and subsequently
replaced SWEB's board of directors and certain senior managers with officers and
employees of companies from within the Southern Company system. Total
consideration for the acquisition was (pound)1.065 billion ($1.785 billion)
excluding a special dividend of (pound)52 million ($87 million) paid by SWEB to
its former shareholders (other than those whose shares the Company had purchased
in the open market). Such dividend, when considered in aggregate with the final
dividend of (pound)23 million ($39 million) paid in October 1995 in respect of
fiscal year 1995, yields the (pound)75 million ($126 million) payment of
pre-acquisition dividends disclosed in the financial statements located
elsewhere in this document.

Accounting for the Acquisition

       The recorded assets and liabilities of SWEB immediately prior to the time
the Company gained effective control of SWEB were (pound)855 million ($1.433
billion) and (pound)528 million ($885 million), respectively. As a result of the
purchase method of accounting, the amount of SWEB's assets recorded on the books
of the Company was increased by (pound)927 million ($1.554 billion) to their
fair value of (pound)1.782 billion ($2.987 billion), and the amount of SWEB's
liabilities recorded on the books of the Company was increased by (pound)372
million ($624 million) to their fair value of (pound)900 million ($1.509
billion). The increase in liabilities included the establishment of reserves
totalling (pound)44 million ($74 million) related principally to staff
reductions and the disposition of ancillary businesses. The resulting difference
between the purchase price of (pound)1.065 billion ($1.785 billion) and the fair
value of the assets and liabilities acquired, including the reserves
established, resulted in goodwill of (pound)183 million ($307 million).

       The information presented for the Pro Forma Fiscal Year 1996 consists of
the historical results of operations of the Predecessor Company prior to the
acquisition and the results of operations of the Successor Company subsequent to
the acquisition, both of which have been adjusted for the effects of the
acquisition as though it had taken place on April 1, 1995. The effects of the
acquisition that are reflected in Pro Forma Fiscal Year 1996 include: (i)
depreciation expense based on property, plant and equipment valued according to
the purchase method of accounting as if the acquisition had occurred on April 1,
1995, (ii) amortization of goodwill valued according to the purchase method of
accounting as if the acquisition had occurred on April 1, 1995, (iii) fair
valuation of existing liabilities and the related interest expense as if the
acquisition had occurred on April 1, 1995, (iv) debt issued to finance the
acquisition and the related interest expense as if the acquisition had occurred
on April 1, 1995, and (v) recognition of pension fund surplus and the reduction
of pension expense in the accounts of the Company.

       The information for Pro Forma Fiscal Year 1996 has been prepared for
illustrative purposes only and, because of its nature, cannot give a complete
picture of the Company's results of operations for that year had the
transactions been consummated on the date assumed and does not project the
Company's financial position or results of operations for any future date or
period. Unaudited amounts have been prepared based upon the audited consolidated
financial statements of the Company, which have been prepared in accordance with
US GAAP.

Significant Events

     The first budget of the newly elected Labour government included a "one-off
windfall levy on the excess profits of the privatized utilities". SWEB estimated
its liability to be approximately (pound)90 million adversely impacting earnings
for the fiscal year 1998. The budget also reduced the UK corporation tax rate
from 33% to 31%. This decrease resulted in an accounting credit reducing SWEB's
provision for deferred income taxes by approximately (pound)22 million in the
fiscal year 1998.

       During fiscal year 1996, the sale by SWEB of its shares in NGG and
related actions produced a nonrecurring pre-tax gain of (pound)14 million over
the fair value established at the time of the Company's acquisition of SWEB and
resulted in net pre-tax cash flow of (pound)241 million. This followed a listing
for the NGG shares on the London Stock Exchange. The listing was conditional
upon the prior demerger of NGG's pumped storage electricity generation business
("PSB") which was sold in December 1995. SWEB had received (pound)36 million of
its share of the total proceeds from that sale by the end of fiscal year 1996
and a further (pound)7 million by the end of fiscal year 1997. The fair value of
this asset at acquisition was assessed at (pound)39 million. In fiscal year 1996
SWEB paid to the Company and the Company paid to Holdings a dividend of
(pound)191 million which was made possible because of the proceeds from the sale
of SWEB's interest in NGG. See Note 11 in the "Notes to the Financial
Statements".

       SWEB has progressively withdrawn from its involvement in non-core
businesses. Neither the contribution to SWEB's or the Company's operating income
from the disposed businesses nor the effect of the dispositions on SWEB's or the
Company's net income was material after taking into account the reserves
established in connection with the acquisition. SWEB sold its appliance
retailing business in June 1995; its appliance servicing business in February
1996; its creditor and warranty insurance business and electrical installation
and contracting business in March 1996; and its interest in a cable television
and telecommunications company in July 1996. SWEB has also restructured its gas
retailing business, which includes a teaming arrangement with another
organization effective from October 1, 1997.


RESULTS OF OPERATIONS

       SWEB was acquired in September 1995 and has undergone certain
restructuring, and the level and cost of financing has changed significantly.
Where relevant, the results for fiscal year 1996 have been presented on a pro
forma basis to provide a comparison with fiscal years 1998 and 1997.

Fiscal Year 1998 Compared with Fiscal Year 1997 Compared with Pro Forma Fiscal
Year 1996

    Earnings

       Earnings in fiscal year 1998 were adversely affected by a (pound)90
million windfall levy assessed against SWEB and an accounting credit reducing
the Company's provision for deferred income taxes by (pound)22 million, as
discussed in "Significant Events" above. The remainder of this discussion is on
items other than the windfall levy and deferred income taxes.

       Operating income increased by (pound)7 million (6%) to (pound)132 million
in the fiscal year 1998 from (pound)125 million in the fiscal year 1997. This
increase is due to a (pound)10 million increase in operating income from the
supply business, partly offset by a (pound)2 million decrease in the
distribution business and a (pound)1 million decrease from other businesses.

       Operating income decreased by (pound)4 million (3%) to (pound)125 million
in the fiscal year 1997 from (pound)129 million in the Pro Forma Fiscal Year
1996. This decrease was due to a (pound)4 million decrease in operating income
from the distribution business, a (pound)3 million decrease in operating income
from the supply business, partly offset by a (pound)3 million increase in
operating income from the ancillary businesses.

       Net income decreased by (pound)2 million (4%) to (pound)53 million in the
fiscal year 1998, before the windfall levy and effect of the tax rate change on
deferred income taxes, from (pound)55 million in the fiscal year 1997. This
decrease was principally due to increased interest expense and customary income
tax charges more than offsetting an increase in operating income discussed
above.


                                      II-3
<PAGE>


         Net income increased by (pound)6 million (12%) to (pound)55 million in
the fiscal year 1997 from (pound)49 million in the Pro Forma Fiscal Year 1996.
This increase was primarily attributable to reduced after-tax interest expense
of (pound)9 million resulting from the repayment during the second half of Pro
Forma Fiscal Year 1996 of debt issued to finance the acquisition and increased
gains on the sale of investments, offset by decreased operating income as
described above.

   Revenues

       Operating revenues decreased by (pound)88 million (10%) to (pound)760
million in the fiscal year 1998 from (pound)848 million in fiscal year 1997
which had increased by (pound)68 million (9%) from (pound)780 million in Pro
Forma Fiscal Year 1996 as follows:

(1)   Intra-business revenues relate to the elimination of intra-business
      revenues in consolidation, principally distribution sales to the supply
      business.

       Two factors determine the amount of revenues produced by the distribution
business: the unit price of the electricity distributed (which is controlled by
the Distribution Price Control Formula) and the number of electricity units
distributed. In July 1995, the Regulator announced the result of distribution
price review which was precipitated by certain market events in the UK electric
utility industry. For SWEB, such announcement meant a real reduction of 11% in
allowable distribution income for the twelve months from April 1, 1996, followed
by an efficiency factor of X = 3% for each year thereafter. The number of units
distributed depends on the demand of SWEB's customers for electricity. That
demand varies based in part upon weather conditions and economic activity.
Revenues from the distribution business decreased by (pound)3 million (1%) to
(pound)228 million for the fiscal year 1998 from (pound)231 million for the
fiscal year 1997 which had decreased by (pound)21 million (8%) from Pro Forma
Fiscal Year 1996 as a result of the following factors:

</TABLE>

       Two factors determine the amount of revenues produced by the supply
business: the unit price of the electricity supplied (which, in the case of the
Regulated Supply Customers until March 31, 1998, is controlled by the Supply
Price Control Formula) and the number of electricity units supplied. From April
1, 1998 the unit price of electricity supplied to Regulated Supply Customers is
subject to Price Cap regulation and, until late 1998, SWEB is expected to have
the exclusive right to supply all Regulated Supply Customers in its Authorized
Area.

       Regulated Supply Customers are generally residential/domestic and small
commercial customers. The volume of unit sales of electricity for Regulated
Supply Customers is influenced largely by the number of customers in the
Authorized Area, weather conditions and prevailing economic conditions. Unit
sales to Unregulated Supply Customers are determined primarily by the success of
the supply business in entering into contracts to supply customers with
electricity.


                                      II-4

<PAGE>


       Revenues from the supply business decreased by (pound)82 million (10%) to
(pound)706 million for the fiscal year 1998 from (pound)788 million for the
fiscal year 1997. The number of electricity units supplied in the fiscal year
1998 also decreased by 10%, which mainly arose from a reduction in units
supplied to Unregulated Supply Customers. In addition to units supplied
reducing, revenues were also reduced due to a reduction in the fossil fuel levy
for the fiscal year 1998, which is passed through to customers. Revenues from
Regulated Supply Customers reduced by 5% mainly due to the reduction in the
fossil fuel levy, together with a reduction in allowable income as set by the
Supply Price Control Formula.

       Revenues from the supply business increased by (pound)62 million (9%) to
(pound)788 million for the fiscal year 1997 from (pound)726 million for the Pro
Forma Fiscal Year 1996. In the fiscal year 1997, the number of electricity units
supplied increased by 23% but total revenues produced by the supply business
increased by only 9%, because a majority of the increase in total units supplied
was to Unregulated Supply Customers, who are the larger energy users charged at
generally lower average unit prices than those charged to Regulated Supply
Customers. Within the regulated market, the number of electricity units
increased by 1%, offset by a reduction in allowable income as set by the Supply
Price Control Formula.

       Revenues from ancillary business decreased by (pound)13 million (21%) to
(pound)50 million in the fiscal year 1998 from (pound)63 million for the fiscal
year 1997. The decrease was principally due to the lower activity in the gas
retailing business due to a restructuring of that business, including a teaming
arrangement with another organization effective from October 1, 1997.

       Intra-business eliminations for fiscal year 1998 decreased by (pound)10
million (4%) from fiscal year 1997 which decreased by (pound)18 million (7%)
from Pro Forma Fiscal Year 1996. Decreases in both years were primarily as the
result of the decrease in revenues from the distribution business described
above.

   Cost of Sales

       Cost of sales decreased by (pound)103 million (17%) to (pound)491 million
in the fiscal year 1998 from (pound)594 million in the fiscal year 1997. The
decrease principally arose from the reduction in energy purchases due to the
decrease in units supplied, together with a decrease in the fossil fuel levy as
mentioned above, and lower volumes in the gas retailing business.

       Cost of sales increased by (pound)90 million (18%) to (pound)594 million
in the fiscal year 1997 from (pound)504 million in the Pro Forma Fiscal Year
1996. This increase was principally the result of an increase in the supply
business cost of sales of (pound)68 million reflecting an increase in purchases
of electricity to supply the increase in unit sales as discussed above.

   Operating Expenses

       Operating expenses increased by (pound)8 million (6%) to (pound)137
million in the fiscal year 1998 from (pound)129 million in the fiscal year 1997.
The increase was principally due to a (pound)6 million increase in selling,
general and administrative costs, together with a (pound)3 million increase in
depreciation and amortization, partly offset by a (pound)1 million decrease in
maintenance costs. The increase in selling, general and administrative costs is
primarily due to the activities and restructuring of the gas retailing business.

       Operating expenses decreased by (pound)18 million (12%) to (pound)129
million in the fiscal year 1997 from (pound)147 million in the Pro Forma Fiscal
Year 1996. This decrease was primarily due to a (pound)4 million decrease in
maintenance costs and a (pound)15 million decrease in selling, general and
administrative costs, which were partially offset by a (pound)1 million increase
in depreciation and amortization resulting from the application of the purchase
method of accounting. The decrease in selling, general and administrative costs
included a decrease in certain classes of computer software development costs
which were expensed during the first half of Pro Forma Fiscal Year 1996 but
which were capitalized subsequently, having satisfied the criteria for
capitalization under the Company's accounting policy (see Note 1 in the "Notes
to the Financial Statements"). The decrease in selling, general and
administrative costs also included a decrease in labor costs resulting from a
reduction in personnel.

   Interest Expense

       Interest expense increased by (pound)5 million to (pound)57 million in
the fiscal year 1998 from (pound)52 million in the fiscal year 1997. In the
latter part of the fiscal year 1997, the Company effectively replaced (pound)325
million of short term bank financed debt with higher margin long term debt.
This, together with an approximate 1% increase in bank borrowing rates during
the fiscal year 1998, and increases in debt as mentioned below, has contributed
to the increase in interest expense.

       The weighted average balance of debt outstanding during the fiscal year
1998 was (pound)654 million at a weighted average interest rate of 7.9% compared
to (pound)621 million at 7.5% during the fiscal year 1997. The change in level
of debt is primarily due to payment of the windfall levy in December 1997.

       Interest expense decreased by (pound)14 million to (pound)52 million in
the fiscal year 1997 from (pound)66 million in the Pro Forma Fiscal Year 1996,
principally as a result of the financing costs associated with the amount of
debt issued for the acquisition. Interest expense for Pro Forma Fiscal Year 1996
reflects interest expense recorded in connection with the acquisition as if the
acquisition had occurred on April 1, 1995, and had been 100% financed with
short-term borrowings at an interest rate of 6% per year. However, in the fiscal
year 1997, the Company benefitted from the retirement of (pound)96 million of
debt and the conversion of (pound)500 million of debt to equity during the
second half of fiscal year 1996. The weighted average balance of debt
outstanding during the fiscal year 1997 was (pound)621 million at a weighted
average interest rate of 7.5% compared to (pound)876 million at 7.0% during the
Pro Forma Fiscal Year 1996.

   Gain on Sale of Investments

       In the fiscal year 1998 there was no gain on the sale of investments. The
gain on the sale of investments was (pound)6 million in the fiscal year 1997.
There was no gain in the Pro Forma Fiscal Year 1996. The gain in the fiscal year
1997 related principally to additional proceeds of (pound)4 million relating to
the demerger of the PSB associated with the sale of NGG and the sale by SWEB of
its interest in a cable television and telecommunications company. See
"Significant Events" above.

   Investment Income

       Investment income increased  by(pound)3 million (50%) to(pound)9 million
in the fiscal  year 1998 from(pound)6 million in the fiscal year 1997, mainly
due to additional dividends from an investment in generating plant.

Future Earnings Potential

       The results of operations discussed above are not necessarily indicative
of future earnings potential. The level of future earnings depends on numerous
factors including the success of the implementation of reorganization plans,
future regulatory price reviews and the level of energy sales and customer
growth/retention in the electricity business.

       The largest portion (approximately 80%) of SWEB's operating income is
derived from its distribution business - essentially the operation and
maintenance of the electricity network in its Authorized Area in the southwest
of England. SWEB is the only distributor of electricity in this area, and
management believes that economic, environmental and regulatory factors are
likely to prevent competitors from entering this business in SWEB's Authorized
Area. Distribution revenues are subject to price-cap regulation. Current
regulation is expected to continue until March 31, 2000. A regulatory review has
commenced which will determine the regulation to apply thereafter.

       In March 1998 the government published a discussion paper ("Green Paper")
on the regulation of the water, electricity, gas and telecommunications
utilities within the UK entitled "A Fair Deal for Consumers: Modernizing the
Framework for Utility Regulation". The government's stated objective for the
review is to set a long term stable framework for utilities which is seen to be
fair by all the interested groups involved. The guiding principles are that
regulation must be transparent, consistent and predictable. The closing date for
responses was May 31, 1998.

       In May 1998 OFFER issued a consultation paper concerning the separation
of businesses in the context of the reviews of the PES's price controls post
2000. It is OFFER's view that full separation of supply and distribution would
be desirable. However, they recognize that it is likely that interim
arrangements will be necessary.

                                     II-6
<PAGE>


       As these papers are only consultative at this time, it is not possible
for the Company to precisely determine the impact until after these issues have
been finalized by the government, and firm proposals are made by OFFER.

       The supply market is subject to change as it is currently partially open
to competition and competition is scheduled to be extended to the remaining
customers as discussed in Item 1 "Business - SWEB's Main Businesses - Supply
Business".

       A possible further impact on future earnings is a court ruling related to
a pension matter. See Note 2 in the "Notes to the Financial Statements" herein
for discussion of this matter. Additionally, other contingencies, including the
possibility of changes in the valuation of the Teesside contract, and other
matters that may affect future earnings potential are discussed in Notes 3 and
4.

       SWEB is heavily dependent upon complex computer systems for all phases of
its operations. The year 2000 issue, common to most corporations, concerns the
inability of certain software and databases to properly recognize date-sensitive
information related to the year 2000 and thereafter. This problem could result
in a material disruption to the Company's operations, if not corrected. SWEB has
assessed and developed a detailed strategy to prevent or at least minimize
problems related to the year 2000 issue. During 1997, resources were committed
and implementation began to modify affected information systems. The total costs
related to the project are not expected to materially impact earnings.
Implementation is currently on schedule. Although the degree of success of this
project can not be determined at this time, management believes there will be no
significant effect on the Company's operations.

New Accounting Standard

       The Financial Accounting Standards Board ("FASB") has issued Statement
No. 130, "Reporting Comprehensive Income", which will be effective for the
fiscal year 1999. This statement establishes standards for reporting and display
of comprehensive income and its components in a full set of general purpose
financial statements. The objective of the statement is to report a measure of
all changes in equity of an enterprise that result from transactions and other
economic events of the period other than transactions with owners (comprehensive
income). Comprehensive income is the total of net income and all other non-owner
changes in equity. The Company will adopt this statement for fiscal year 1999.
Currently, the adoption of this statement will not have a material effect on the
Company's financial results.


FINANCIAL CONDITION

Overview

       The major change in the Company's financial condition during the fiscal
year 1998 was the addition by SWEB of approximately (pound)81 million in
property, plant, and equipment, largely in respect of the distribution network.
The funds required for the plant additions were derived primarily from
operations. It is expected that SWEB's capital requirements in the foreseeable
future for investment in property will be generated from operating activities.

       Demand for electricity in Great Britain, in general, and in SWEB's
Authorized Area, in particular, is seasonal, with demand being higher in the
winter months and lower in the summer months. SWEB balances the effect of this
and other cyclical influences on its working capital needs with drawings under
its available credit facilities.

       The Company's sole investment and only significant asset is the entire
share capital of SWEB. The Company is therefore dependent upon dividends from
SWEB for its cash flow. SWEB can make distribution of dividends to the Company
under English law to the extent that it has distributable reserves, subject to
the retention of sufficient financial resources to conduct its supply and
distribution businesses as required by its regulatory license. The Company
believes that currently sufficient distributable reserves will continue to exist
at SWEB to allow for reasonable and necessary dividends from SWEB, through
operations, to be distributed to the Company. In the UK, the Accounting
Standards Board is currently reviewing the treatment of deferred income tax
accounting. If full provision for deferred tax were required, SWEB's
distributable reserves could be eliminated.
    
                                  II-7

Derivative Financial Instruments

         The Company and SWEB have non-trading operations that are exposed to
certain market risks including changes in interest rates, cross currency
exchange rates and the volatility of prices of electricity purchased in the
Pool. To mitigate changes in cashflow attributed to these exposures the Company
has entered into various derivative financial instruments, the sole purpose of
which is to hedge exposure in these areas.

       Interest rate swaps are used to hedge specific debt issuances and
therefore qualify for hedge accounting. Where debt is issued in US dollars,
currency swaps effectively convert the exposure to sterling. The interest rate
differential is reflected as an adjustment to interest expense over the life of
the instruments. Derivative exposures for interest rate and cross currency swaps
are measured using mark-to-market valuations.

       If the Company sustained a 100 basis point change in interest rates for
all variable rate debt, the change would affect annualized interest expense by
approximately (pound)1 million i.e. 1% on (pound)78 million variable rate debt
as at March 31, 1998. Based on the Company's overall interest rate exposure as
at March 31, 1998, including derivative and other interest rate sensitive
instruments, a 100 basis point change in interest rates would not materially
affect the consolidated financial statements.

         In addition, SWEB utilizes CFD's to mitigate its exposure to volatility
in the prices of electricity purchased through the Pool. The gains and losses on
such contracts are deferred and recognized as electricity is purchased.

       The Company does not have an exposure to changes in exchange rates
between (pound) sterling and the US dollar as it uses both long term and short
term cross-currency agreements to fully hedge any debt issued in US dollars.
Therefore a 10% sustained decline of the US dollar would not affect these swaps
in respect of the consolidated financial statements.

Financing Activities

         During the fiscal year 1998 the Company and SWEB entered into
(pound)100 million of fixed rate sterling interest swaps, (pound)25 million ($42
million) in December 1997 and (pound)75 million ($125 million) in January 1998.

         At March 31, 1998, the Company and SWEB have sterling interest rate
swaps expiring between 2001 and 2012, with notional amounts totalling (pound)600
million ($1,006 million), and have cross currency swaps expiring between 2001
and 2007, with notional amounts totalling (pound)350 million ($587 million).

Sources of Capital

         The Company has a US commercial paper program under which the maximum
available is $520 million. This program is supported by a swingline and
revolving credit facility provided by a syndicate of banks. The amount available
under the program, which is supported by the swingline and revolving credit
facility, at March 31, 1998 was $164 million. SWEB enters into foreign currency
contracts to hedge the currency risk associated with the interest and principal
of each utilization under this program.

         SWEB actively manages its short-term debt, which includes a number of
bank lines of credit in addition to the commercial paper program. At March 31,
1998 the Company and SWEB together had short-term debt of (pound)363 million
($608 million) outstanding ($134 million from commercial paper, $222 million
from swingline and revolving credit facility, and $252 million in other
short-term loans). The increase in short-term debt is largely due to the payment
of the first installment of the windfall levy.

       To meet short-term cash needs and contingencies, the Company and SWEB
together had at March 31, 1998 approximately (pound)5 million of cash and
(pound)180 million of unutilized committed lines of credit with banks. Also
available was $164 million of the swingline and revolving credit facility
mentioned above. The Company currently has sufficient liquidity to meet the
second installment of the windfall levy, and the pension matter, discussed in
Item 1 - "Business", and Note 2 in the "Notes to the Financial Statements"
herein.

                               MANAGEMENT'S REPORT
                               1998 Annual Report

       The management of the Company has prepared -- and is responsible for --
the consolidated financial statements and related information included in this
report. These statements were prepared in accordance with generally accepted
accounting principles appropriate in the circumstances and necessarily include
amounts that are based on the best estimates and judgments of management.
Financial information throughout this annual report is consistent with the
financial statements.

       The Company maintains a system of internal accounting controls to provide
reasonable assurance that assets are safeguarded and that books and records
reflect only authorized transactions of the Company. Limitations exist in any
system of internal controls, however, based on a recognition that the cost of
the system should not exceed its benefits. The Company believes its system of
internal accounting controls maintains an appropriate cost/benefit relationship.

       The Company's system of internal accounting controls is evaluated on an
ongoing basis by the Company's internal audit staff. The Company's independent
public accountants also consider certain elements of the internal control system
in order to determine their auditing procedures for the purpose of expressing an
opinion on the financial statements.

       Management believes that its policies and procedures provide reasonable
assurance that the Company's operations are conducted according to a high
standard of business ethics.

       In management's opinion, the consolidated financial statements present
fairly, in all material respects, the financial position, results of operations,
and cash flows of the Company and its subsidiaries in conformity with generally
accepted accounting principles in the United States.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To the Board of Directors of Southern Investments UK plc:


       We have audited the accompanying consolidated balance sheets of SOUTHERN
INVESTMENTS UK plc (the "Company" being a company incorporated in England and
Wales) and SUBSIDIARIES as of March 31, 1998 and 1997, the related consolidated
statements of income, changes in stockholder`s equity and cash flows for the
years ended March 31, 1998 and 1997 and for the period from inception (June 23,
1995) to March 31, 1996. In addition we have audited the accompanying
consolidated statements of income, changes in stockholder's equity, and cash
flows of SOUTH WESTERN ELECTRICITY plc and SUBSIDIARIES for the period from

responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

       We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

       In our opinion, the financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Southern Investments UK plc and subsidiaries as of March 31, 1998 and 1997 and
the consolidated results of its operations, changes in stockholder's equity and
cash flows for the years ended March 31, 1998 and 1997 and for the period from
inception (June 23, 1995) to March 31, 1996, and the consolidated results of the
operations, changes in stockholders' equity, and cash flows of South Western
Electricity plc and subsidiaries for the period from April 1, 1995 to September
17, 1995, in conformity with generally accepted accounting principles in the
United States.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

                                 MARCH 31, 1998

1.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

General

       Southern Investments UK plc (the "Company") is a wholly-owned subsidiary
of SWEB Holdings Limited ("Holdings"). Throughout the period under review, 75%
of Holdings was owned indirectly by Southern and 25% was owned indirectly by
PP&L Resources. On June 18, 1998, Southern sold a further share of its ownership
in Holdings to PP&L Resources as set out in Note 13. The Company was
incorporated as a public limited company under the laws of England and Wales on
June 23, 1995 as a vehicle for the acquisition of South Western Electricity plc
(together with its subsidiaries, "SWEB"). On September 18, 1995, the Company
gained effective control of SWEB, having acquired approximately 84% of its
shares (the "Acquisition"). Accordingly, the Company has designated September
18, 1995 as the effective date of the Acquisition (the "Acquisition Date").
Given that SWEB represents substantially all of the current operations of the
Company, SWEB is considered the Predecessor Company (the "Predecessor Company").
All references in the financial statements to the Successor Company represent
the Company and its subsidiaries and to the Predecessor Company represent South
Western Electricity plc and its subsidiaries. See Note 7 for a further
discussion of the Acquisition. The pro forma accounts for 1996 are based on the
adjusted results for these two entities for the 12 months to March 31, 1996, as
set out in Note 14.

Basis of Presentation

       The financial statements of the Company are presented in pounds sterling
((pound)) and in conformity with accounting principles generally accepted in the
United States. The accompanying financial statements have not been prepared in
accordance with the policies of Statement of Financial Accounting Standards No.
71, "Accounting for the Effects of Certain Types of Regulation" ("SFAS No. 71").
This pronouncement, under which most US electric utilities report financial
statements, applies to entities which are subject to cost-based rate regulation.
By contrast, SWEB is not subject to rate regulation, but, rather is subject to
price cap regulation (Note 3) and therefore the provisions of SFAS No. 71 do not
apply. Financial statements presented in accordance with SFAS No. 71 contain
deferred items which have not yet been included in rates charged to customers in
compliance with the respective regulatory authorities, but which would have been
included in the income statement of enterprises in general under US GAAP. The
accompanying financial statements of the Company do not contain such deferrals.

       The consolidated financial statements include the accounts of the Company
and its wholly owned and majority owned subsidiaries and have been prepared from
records maintained by SWEB in the United Kingdom. All significant intercompany
accounts and transactions have been eliminated in consolidation. Investments in
companies in which the Company's ownership interests range from 20% to 50% and
the Company exercises significant influence over operating and financial
policies are accounted for using the equity method. Other investments are
accounted for using the cost method (Note 11).

       Solely for the convenience of the reader, certain pounds sterling amounts
included in the financial statements have been translated into US dollars at the
exchange rate of $1.6765 = (pound)1.00, the noon buying rate in New York City
for cable transfers in pounds sterling as certified for customs purposes by the
Federal Reserve Bank of New York on March 31, 1998. The following table sets out
this rate for previous periods:

           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS-(Continued)


Use of Accounting Estimates

       The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expense during the reporting
period. Actual results could differ from those estimates.

Revenue Recognition

       SWEB records revenue net of value added tax ("VAT") and accrues revenues
for services provided but unbilled at the end of each reporting period. SWEB
purchases power primarily from a market for the bulk trading of electricity (the
"Pool").

       The Company has a diversified base of customers. No single customer
comprises 10% or more of revenues.

Cash and Cash Equivalents

       The Company considers all short-term investments with an original
maturity of three months or less to be cash equivalents.

Property, Plant, and Equipment

       Property, plant, and equipment are recorded at fair market value as
adjusted at the acquisition date in accordance with Accounting Principles Board
Opinion No. 16, "Accounting for Business Combinations" ("APB No. 16"). Items
capitalized subsequent to the Acquisition are recorded at original cost, which
includes materials, labor, appropriate administrative and general costs, and the
estimated cost of funds used during construction. The cost of maintenance,
repairs, and replacement of minor items of property is charged to maintenance
expense.

       Depreciation of the recorded cost of depreciable property, plant, and
equipment is provided by using primarily composite straight-line rates, which
approximate 3.2% per year (2.5% per year for depreciable utility plant in
service). Upon the retirement or sale of assets, the costs of such assets and
the related accumulated depreciation are removed from the balance sheet and the
gain or loss, if any, is included in income.

Information Technology Consultancy and Development Costs

       Significant information technology ("IT") consultancy and development
costs are capitalized when they become technologically feasible and are
amortized over their estimated useful economic life from the date of first use.
Other IT consultancy and development costs are charged to income in the period
in which they are incurred. This policy was adopted effective October 1, 1995 as
the Company embarked on a significant program of investment and will be
incurring significant development costs which are fundamental to the future
performance of the business and which will benefit the business for a number of
years. The Directors are of the opinion that in relation to the planned
development costs to be incurred in the future, the policy followed by the
Predecessor Company of writing off such costs to the Statement of Income does
not give a fair reflection of the period over which the benefits will accrue.
Prior to this change in accounting policy the Company expensed all IT
consultancy and development costs as incurred. The effect of adopting this
policy has resulted in the capitalization of (pound)14 million of costs in the
fiscal year 1998 and (pound)11 million of costs in the fiscal year 1997.

Goodwill

       The Company amortizes costs in excess of fair value of net assets of the
business acquired using the straight-line method over a period of 40 years.
Recoverability (performed on the basis of undiscounted operating cash flow
analysis) is reviewed annually or sooner if events or changes in circumstances
indicate that the carrying amount may exceed fair value, in accordance with the
provisions of Statement of Financial Accounting Standards ("SFAS") No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of". Goodwill shown in the accompanying consolidated financial
statements relates to the acquisition of SWEB.

Investments

       The Company accounts for its current investments in accordance with SFAS
No. 115, "Accounting for Investments for Certain Debt and Equity Securities".
These investments represent investments in debt securities, which management
classifies as available-for-sale securities in accordance with SFAS No. 115. The
Company's long-term investments consist of investments accounted for using the
cost method (Note 11).

Income Taxes

       SFAS No. 109, "Accounting for Income Taxes", requires the asset and
liability approach for financial accounting and reporting for deferred income
taxes. The Company uses the liability method of accounting for deferred income
taxes and provides deferred income taxes for all significant income tax
temporary differences.

Financial Instruments

       Non-trading derivative financial instruments are used to hedge exposures
to volatility in electricity prices and fluctuations in interest rates and
foreign currency exchange rates. Gains and losses on qualifying hedges are
deferred and recognized either in income or as an adjustment to the carrying
amount when the hedged transaction occurs.

Reclassifications

       Certain prior years' data presented in the consolidated financial
statements has been reclassified to conform with the current year presentation.

       SWEB has two pension plans, a defined contribution plan and a defined
benefit plan.

Defined Contribution Plan

       The defined contribution plan was established in fiscal year 1994. The
assets of the defined contribution plan are held and administered by an
independent trustee. Contributions to the plan by SWEB on behalf of its
employees were (pound)0.2 million ($0.3 million) for the fiscal year 1998, and
(pound)0.1 million for the fiscal year 1997. Contributions in prior periods were
not material.

Defined Benefit Plan

       SWEB participates in the Electricity Supply Pension Scheme, which
provides pension and other related defined benefits, based on final pensionable
pay, to substantially all employees throughout the Electricity Supply Industry
in the UK. Contributions to the plan by SWEB on behalf of its employees were
(pound)0.3 million ($0.5 million) for the fiscal year 1998, (pound)0.6 million
for the fiscal year 1997, (pound)4.8 million for the period from inception (June
23, 1995) through March 31, 1996, and (pound)3.7 million for the period from
April 1, 1995 to September 17, 1995.

       In accordance with SFAS No. 87, as of the date of the Acquisition, the
assignment of the purchase price to individual assets acquired and liabilities
assumed includes the plan assets in excess of the projected benefit obligation.
SWEB uses the "entry age normal method with a frozen initial liability"
actuarial method for funding purposes. Amounts funded to the pension trust are
primarily invested in equity and fixed-income securities. SFAS No. 87 requires
use of the "projected unit credit" actuarial method for financial reporting
purposes.

Pensions Contingency

       The Pensions Ombudsman (a UK statutorily appointed independent
arbitrator) has issued a determination in favor of complaints made by members of
the Electricity Supply Pension Scheme ("ESPS") relating to another employer's
use of ESPS surplus to offset the employer's costs of providing early pensions
on redundancies and certain other items. Under that determination the Pensions
Ombudsman directed the employer to pay into ESPS the amount of that use of the
surplus plus interest. The determination was challenged in the High Court by the
employer, and the High Court upheld the employer's appeal in a judgment
delivered on June 10, 1997. The High Court also granted the complainants leave
to appeal to a higher court. No date has yet been set for any hearing in the
Appeal court. If the complainants' appeal is successful, either at the Appeal
court or on a subsequent appeal to the House of Lords, it will have an adverse
effect on SWEB. Unless the High Court decision is reversed, this case should not
impact SWEB significantly; however it is not practical to make an estimate of
the exposure at the present time.

3. REGULATORY MATTERS

Distribution

       OFFER controls the revenues generated by SWEB in its distribution
business by applying a price control formula, P + RPI -X, where P is the price
level at the beginning of each new regulatory period, RPI is the change in the
Retail Price Index and X is an adjustment factor determined by OFFER. X is
currently 3%.

       The DPCF is usually set for a five-year period, subject to more frequent
adjustments as determined necessary by the Regulator. At each review, the
Regulator can require a one-time price adjustment. An initial review by the
Regulator of allowable income in the distribution business led to a reduction of
the price level by 14% for SWEB starting April 1, 1995, followed by efficiency
factors of X = 2% for each year until March 2000. On July 6, 1995, the Regulator
announced the result of a further distribution price review which was
precipitated by certain market events in the UK electric utility industry. For
SWEB, such announcement meant a real reduction of 11% in allowable distribution
income for the twelve months from April 1, 1996, followed by an efficiency
factor of X = 3% for each year, before an allowed increase for inflation. The
Regulator is currently undertaking the next DPCF review expected to become
effective from April 1, 2000.

Supply

       Within the supply business, customers fall into the two categories of
Unregulated and Regulated Supply Customers.

       Until March 31, 1998, Unregulated Supply Customers were defined as
customers who had an electricity demand of more than 100kW. From April 1, 1998,
Unregulated Supply Customers are defined as customers who are non-domestic and
who have an annual consumption in excess of 12,000kWh. Unregulated Supply
Customers may contract for their electricity from any holder of a PES license.
However, those customers who were Regulated Supply Customers until the change in
definition must continue to take supply from their host REC until competition
commences in that REC's Authorized Area (see below).

       Regulated Customers are those customers who are not Unregulated Supply
Customers and largely comprise domestic and small business customers. Prices
charged to Regulated Supply Customers by a REC within its Authorized Area are
controlled by regulation. Until March 31, 1998, the calculation of the maximum
supply charge was based on a SPCF, similar to the DPCF, plus an ability to pass
through certain costs, principally the costs of energy purchases, transmission
and distribution use of system charges. For the four-year period ending March
31, 1998, an efficiency factor of X = 2% (before an allowed increase for
inflation) was applied to SWEB, offset by an allowance for both unit and
customer growth. From April 1, 1998 supply business charges to Regulated Supply
Customers is subject to a Price Cap instead of being based on the SPCF; the
concept of pass through costs no longer applies.

        SOUTHERN INVESTMENTS UK plc AND SUBSIDIARIES (SUCCESSOR COMPANY)
    AND SOUTH WESTERN ELECTRICITY plc AND SUBSIDIARIES (PREDECESSOR COMPANY)
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

       Following the announcement by the Regulator on October 16, 1997, in
respect of its latest supply price review for Regulated Supply Customers
effective from April 1, 1998, SWEB has implemented a tariff reduction of 2.8%
effective from that date. A further 3% reduction (before an allowed increase for
inflation) will be implemented for fiscal year 2000. This average tariff
reduction primarily reflects the expected reduction in power purchase costs
after March 31, 1998 when expensive CFDs, (Note 8), agreed by the government at
the time of privatization of the electricity industry, will end, and the fossil
fuel levy will be further reduced.

       The exclusive right to supply Regulated Supply Customers (as defined
prior to April 1, 1998) was scheduled to be phased out over a six-month period
commencing April 1, 1998, after which all supply customers would have the
ability to choose their electricity supplier. An announcement by the Regulator
on October 16, 1997 stated that the exclusive right to supply Regulated Supply
Customers should be phased out from September 1998. Each REC has an authorized
start date for competition to commence in its Authorized Area, and SWEB's is
towards the end of calendar year 1998. Once a REC's Authorized Area is open to
competition, then it can compete in the Authorized Area of other RECs where
competition has commenced, and vice versa.

       The Regulator has also proposed a penalty on all RECs, including SWEB,
related to the delay in opening competition to Regulated Supply Customers beyond
the April 1, 1998 deadline; any penalty imposed on SWEB is not expected to have
a material impact on earnings. The supply tariffs in fiscal years 1999 and 2000
represent maximum price restraints intended to protect each REC's Regulated
Supply Customers, which it supplies within its Authorized Area.

4. COMMITMENTS AND CONTINGENT MATTERS

Power Purchase Agreements

       SWEB has entered into a contract relating to the purchase of 200
megawatts of capacity from a 7.69% owned related party, Teesside Power Limited
("Teesside"), for a period of 15 years beginning April 1, 1993. The contract
sets escalating electricity purchase prices at predetermined levels. The Company
has recognized an accrual at the acquisition date for the excess of these
Teesside power purchase costs in each year over an estimate of the equivalent
Pool costs in that respective year. These costs have been discounted at an
appropriate rate to their present value of (pound)72 million ($121 million) at
March 31, 1998 and (pound)69 million at March 31, 1997. Over the past two years,
the Pool prices have been less than anticipated when the accrual was recognized.
The Company is continuing to review the trend of Pool prices and an adjustment
to the provision may be required in the future.

Operating Leases

       SWEB has commitments under operating leases with various terms and
expiration dates. Expenses associated with these commitments totalled (pound)5
million ($8 million) for the fiscal year 1998, (pound)4 million for the fiscal
year 1997, (pound)3 million for the period from inception (June 23, 1995) to
March 31, 1996, and (pound)3 million for the period from April 1, 1995 to
September 17, 1995.

       Estimated minimum rental commitments for noncancelable operating leases
were as follows at March 31, 1998 (in millions):

Labor Subject to Collective Bargaining Agreements

       Substantially all of SWEB's employees are subject to one of two
collective bargaining agreements. Such agreements are ongoing in nature, and
SWEB's employee participation level is consistent with that of the electric
utility industry in the UK.

5. SEGMENT AND RELATED INFORMATION

       Effective March 31, 1998, the Company adopted FASB Statement No. 131,
"Disclosure About Segments of an Enterprise and Related Information". The
Company is primarily engaged in two electric industry segments: distribution,
which involves the transmission of electricity across its network and its
transfer and delivery to its customers, and supply, which involves bulk purchase
of electricity from the Pool and arranging for its sale and transfer to its
customers. Information about the Company's operations in these individual
segments, which also reflect its products and services, is detailed below. All
revenues are in respect of sales to customers in the UK.

       On July 2, 1997 the newly elected Labour government presented its first
budget which included a "one-off windfall levy on the excess profits of the
privatized utilities". Based upon the legislation, SWEB estimated its liability
to be approximately (pound)90 million. The levy is payable in two equal
installments. The first installment was paid on December 1, 1997 and the second
will be paid on or before December 1, 1998. The legislation also reduced the UK
corporation tax rate from 33% to 31% with effect from April 1, 1997. Such a
decrease resulted in an accounting credit reducing the Company's provision for
deferred income taxes by approximately (pound)22 million.

       The tax effects of temporary differences between the carrying amounts of
assets and liabilities in the financial statements and their respective tax
bases, which give rise to deferred tax assets and liabilities, are as follows
(in millions):

7. ACQUISITION

       The acquisition of SWEB in the amount of (pound)1.065 ($1.785) billion
was accomplished through the purchase of shares via both cash and non-cash
consideration (see accompanying consolidated statement of cash flows) between
July and November 1995, and was accounted for using the purchase method of
accounting in accordance with APB No. 16. The purchase price of SWEB has been
allocated to the underlying assets and liabilities based on estimated fair
values at the acquisition date. The acquisition cost exceeded the fair market
value of net assets acquired, including (pound)28 million ($47 million) of
acquisition related costs, by (pound)183 million ($307 million) and is
considered goodwill. The operating results of SWEB have been included in the
Company's financial statements from the effective date of the acquisition.

       The following unaudited pro forma information has been prepared assuming
that the acquisition had occurred at the beginning of the respective periods.
The pro forma adjustments made are detailed in Note 14. The pro forma
information is presented for informational purposes only and may not be
indicative of the results of operations as they would have been had the
acquisition occurred at the beginning of the respective periods, nor is the
information necessarily indicative of the results of operations which may occur
in the future.

8. FINANCIAL INSTRUMENTS

       SWEB utilizes CFDs to mitigate its exposure to volatility in the prices
of electricity purchased through the Pool. Such contracts allow the Company to
effectively convert the majority of its anticipated Pool purchases from market
prices to fixed prices. SWEB's goal is to obtain competitively priced contracts
to cover the majority of its purchase requirements. The gains and losses on such
contracts are deferred and recognized as electricity is purchased. Management
believes that the fair value of these contracts at present is not materially
different than the fair value determined at acquisition. SWEB also has
commitments to purchase capacity under its long term contracts. See Note 4 where
these contracts are discussed in greater detail.

       The Company and SWEB utilize interest rate swaps to minimize borrowing
costs and mitigate their exposure to fluctuations in interest rates by allowing
them to convert their outstanding variable rate debt into fixed rate debt. These
swaps are designated as hedges of underlying debt obligations and, as such, the
interest rate differential is reflected as an adjustment to interest expense
over the life of the swaps. At March 31, 1998, sterling interest rate swaps
expiring between 2001 and 2012 with notional amounts totalling (pound)600
million ($1,006 million), resulted in an unrealized loss of (pound)39 million
($65 million).

       Foreign currency swaps are used by the Company and SWEB to hedge exposure
to currency fluctuations for US dollar denominated debt. Gains and losses on
these hedges are deferred and recognized as an adjustment to the carrying amount
when the hedged transaction occurs. At March 31, 1998, currency swaps expiring
between 2001 and 2007 with notional amounts totalling (pound)350 million ($587
million), resulted in an unrealized profit of (pound)4 million ($6 million).

       The Company is exposed to losses in the event of nonperformance by
counterparties to its financial instrument contracts. To mitigate this credit
risk, the Company selects counterparties based on their credit ratings, limits
its exposure to any one counterparty under defined guidelines, and monitors the
market position of the programs and its relative market position with each
counterparty. The Company does not expect any of the counterparties to fail to
meet their obligations.

9. CAPITAL BUDGET

       The Company's capital expenditure for the fiscal year 1998 was (pound)81
million ($136 million); for the fiscal years 1999 and 2000 capital expenditures
are estimated to be (pound)71 million and (pound)67 million respectively. The
capital budget is subject to periodic review and revision, and actual capital
cost incurred may vary from the above statement because of numerous factors. The
factors include: changes in business conditions; revised load growth
projections; change in regulatory requirements; and increasing costs of labor,
equipment, and materials.

10. FINANCING

       The Company has $500 million Senior Notes in the US, of which some $168
million of the Senior Notes are due for redemption in 2001 and $332 million in
2006; the Senior Notes are at rates of 6.375% and 6.8% respectively. The Company
entered into currency swap transactions that effectively convert the US dollar
obligations of the Senior Notes into pounds sterling obligations, with a nominal
value of (pound)300 million.

       The Company has a US commercial paper program under which the maximum
available is $520 million. This program is supported by a swingline and
revolving credit facility provided by a syndicate of banks. The amount available
under the program, which is supported by the swingline and revolving credit
facility, at March 31, 1998 was $164 million. SWEB enters into foreign currency
contracts to hedge the currency risk associated with the interest and principal
of each utilization under this program.

       During the fiscal year 1998 the Company and SWEB entered into a further
(pound)100 million of fixed rate sterling interest swaps. At March 31, 1998, the
Company and SWEB have sterling interest rate swaps expiring between 2001 and
2012 with notional amounts totalling (pound)600 million ($1,006 million), and
cross currency swaps expiring between 2001 and 2007 with notional amounts
totalling (pound)350 million ($587 million).

       Southern Investments UK Capital Trust I (the "Trust"), issued $82 million
of its 8.23% preferred securities and invested the proceeds thereof in 8.23%
subordinated debentures issued by the Company, which are scheduled to mature on
February 1, 2027. The Company guarantees the Trust's obligations under the
preferred securities. The Company has also entered into foreign currency swap
contracts to hedge the currency risk associated with the interest and principal
on the preferred securities, by swapping the US dollar liabilities back to
pounds sterling for the period to February 2007. The nominal value of the
swapped liabilities is (pound)50 million. The Company owns all of the common
securities of the Trust, all of the assets of which are the aforementioned
subordinated debentures of the Company in the aggregate principal amount of
$84.5 million.

       The Company considers that the mechanisms and obligations relating to the
preferred securities, taken together, constitute a full and unconditional
guarantee by the Company of the Trust's payment obligations with respect to the
preferred securities.

11. INVESTMENTS

       The Company's long-term investments accounted for under the cost method
consist of its 7.69% ownership of Teesside (Note 4), the fair value of which is
not readily determinable. The Company's short-term investments are classified as
available-for-sale under SFAS No. 115, the fair value of which approximated cost
at March 31, 1998.

       During fiscal year 1996, SWEB sold its share of NGG into the market,
following the listing of the NGG shares on the London Stock Exchange in December
1995. At the Acquisition Date, the eventual listing of shares in NGG was not
certain as it required numerous actions by the 12 RECs, NGG and the UK
government, followed by the consent of the shareholders given at meetings of
each of the 12 RECs on the terms of a listing. Management determined that it had
all the facts necessary to complete a calculation of the fair value of its long
term investment in NGG, and it utilized a discounted cash flow methodology to
determine the asset's fair value shortly after the Acquisition Date in
accordance with APB No. 16.

    AND SOUTH WESTERN ELECTRICITY plc AND SUBSIDIARIES (PREDECESSOR COMPANY)
           NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS-(Continued)

       The Company's valuation of (pound)199 million was within the range of
independent appraisals of NGG performed during the same period. Subsequently,
certain facts and circumstances changed which increased the value of the
Company's investment in NGG. SWEB disposed of its shares for (pound)213 million,
resulting in a pretax gain of (pound)14 million. This gain is nonrecurring in
nature as it is the result of changes in circumstances after the fair valuation
of the investment in NGG resulting from the application of APB No.
16 which valuation was finalized shortly after the Acquisition Date.

       The offering of NGG was conditional on the prior demerger of PSB which
was completed in November 1995. The fair value of SWEB's holdings at acquisition
in PSB was assessed at (pound)39 million. PSB was subsequently sold. At March
31, 1997, proceeds of (pound)43 million had been received; a gain of (pound)4
million had been recognized in fiscal year 1997.

12. COMMON STOCKHOLDER'S EQUITY

       As discussed in Note 7, the Company obtained effective control of SWEB in
September 1995. During October 1995, (pound)315 million of advances from the
parent of the Company were converted to share capital, an equity contribution of
(pound)185 million was received from the parent of the Company, and a
combination of short-term and long-term debt financing was obtained to
facilitate the payment of the former shareholders. These transactions are
reflected in the consolidated statements of cash flows.

       Dividends in the amount of (pound)191 million were declared and paid by
the Company during the period ending March 31, 1996 as proceeds from the sale of
the Company's shares in NGG (Note 11) provided cash in addition to that provided
from operations during the period.

       The Company's sole investment and only significant asset is the entire
share capital of SWEB. The Company is therefore dependent upon dividends from
SWEB for its cash flow. SWEB can make distribution of dividends to the Company
under English law to the extent that it has distributable reserves, subject to
the retention of sufficient financial resources to conduct its supply and
distribution businesses as required by its regulatory license. The Company
believes that currently sufficient distributable reserves will exist at SWEB to
allow for any and all cash flow generated at SWEB through operations to be
distributed to the Company through dividends to the Company. In the UK, the
Accounting Standards Board is currently reviewing the treatment of deferred
income tax accounting. If full provision for deferred tax were required, SWEB's
distributable reserves could be eliminated.

13. SUBSEQUENT EVENT

       On June 18, 1998, Southern sold an additional 26 percent interest in
Holdings to PP&L Resources for $170 million.

       PP&L Resources initially purchased a 25 percent stake in Holdings in July
1996. This further sale will increase PP&L Resources' economic interest in
Holdings to 51 percent.

       Under the terms of the agreement, Southern will retain operational and
management control of SWEB and the Holdings group. Southern will continue to
hold a majority of the voting shares in Holdings and will retain a majority of
the Board of Directors.  In addition, all members of SWEB's senior management
team will remain in place.

(1)   Depreciation expense which would have been recorded based on the valuation of property, plant, and equipment recorded in
      connection with the purchase business combination, as if such combination had occurred on April 1, 1995. It has been provided
      using composite straight line rates which approximate 3.1% on an asset value of (pound)1,190 million for 170 days, less
      depreciation already charged to the Predecessor Company's consolidated statement of income.

(2)   Amortization of goodwill recorded in connection with the purchase business combination as if the combination had occurred on
      April 1, 1995.

(3)   Reflect the fair value of long-term debt obligations and associated interest expense recorded in connection with the purchase
      business combination as if the combination had occurred on April 1, 1995. The charge relates to notional interest ((pound)2
      million) on a discounted provision for onerous purchase contracts ("Teesside"), partly offset by a reduction in interest to
      market rates on the HM Government debt put in place at privatization ((pound)1 million).

(4)   Reflect the interest expense recorded in connection with the purchase business combination as if the combination had occurred
      on April 1, 1995 and had been 100% financed with short-term borrowings at an interest rate of 6% per year. The impact of a
      1/8% change in the assumed interest rate  would change income from continuing operations by (pound)0.4 million.

(5)   Remove gain on sale of investment in NGG and costs incurred by the Predecessor Company relating to bid defense associated
      with the Acquisition. An extraordinary gain of (pound)6 million ($10 million) on early extinguishment of debt during the
      successor period above, normally  shown after income from continuing operations, has also been removed.

of directors of the Company pursuant to a Shareholders' Agreement dated July 1,
1996 (the "Shareholders' Agreement") among Southern Electric
International-Europe Inc. ("SEI-Europe"), PMDC and Holdings. The Shareholders'
Agreement provides that each shareholder of Holdings owning 10 percent or more
of the shares of Holdings has the right to elect one director for every 10
percent held. This right applies not only to the board of directors of Holdings
but also extends to the board of directors of the Company as a wholly-owned
subsidiary of Holdings. Thus, PMDC, as holder of 25 percent of the shares of
Holdings during the period under review, had the right to elect two directors to
the board of the Company. Accentacross and Mighteager are represented on the
board of directors of the Company by Messrs. Fagan and Petersen, respectively.

Statements".

     (iii)In  summary  the  effect  of the  modifications will be to amend  the
          charge restriction conditions so that:

          -    from 1 April  1998,  the  control  of  charges for the supply of
               electricity  will apply only to domestic  customers  and to other
               customers consuming no more than 12000 kWh per year;

          -    except  with the consent of the  Director  such  customers shall
               continue to be offered the tariffs at present available to them,

          -    for  the  year  commencing  1  April  1998,  in  respect of such
               customers

               -    the average price must fall, in comparison with the average
                    price   obtaining  on  1  August  1997,   by the  following
                    percentage in real terms: being 8.9 for Eastern Electricity
                    plc, 6.3 for East Midlands Electricity plc, 11.8 for London
                    Electricity  plc,  5.8 for Manweb  plc,  7.1  for  Midlands

                    Electricity Group plc;

               -    the prices charged to those on standard domestic tariff who
                    consume  3300  kWh in  that  year  must  fall  by  the  same
                    percentage in real terms;

               -    the prices charged to other domestic customers must fall by
                    3 per cent in real terms;
     <PAGE>

                    increase in real terms;
    
               -    no standing charge may be increased in real terms;

               -    the prices to customers on a domestic prepayment tariff must
                    be  reduced  by  the  same   proportion as  prices  on  the
                    Comparable domestic credit tariff;

          -    for the subsequent year, prices must be reduced by 3 per cent in
               real terms;

          -    adjustments  may be made to prices to take account of changes in
               the rate of fossil fuel levy,  over-recovery  in previous years,
               delay in introducing competition or unexpected movement in costs;

          -    from 1 April 1998, the allowed maximum average charge per unit of
               electricity distributed by each licence holder

               -    shall be increased to account for the costs of  establishing
                    and operating  certain services which each licence holder is
                    required  by its  PES  licence  to  undertake in  order  to
                    facilitate competition in electricity supply;

               -    may be adjusted  downwards  in  circumstances: in which the
                    introduction  of competition in  electricity, supply to any
                    part of Great Britain is delayed beyond April 1998;  and in
                    which  the  phased  introduction of  competition  into  the
                    authorised  area of each  licence holder is  delayed at any
                    stage beyond July 1998.

     A copy of the  statement of 16 October 1997 and of the present  draft of
     the  modifications can be obtained (free of charge) from the Office of
     Electricity Regulation.

     Any representations  or  objections to the proposed  modifications may be
     made on or before 20  February  1998 to the  Director at the Office of
     Electricity  Regulation,  Hagley House, 83-85 Hagley Road,  Edgbaston,

         authorise the Chief Executive to maintain a document (the "1998
         Framework Agreement") which shall contain points of principle and text

         Framework Agreement will be revised as further principles and/or text
         are agreed by the Executive Committee or Pool Members in general
         meeting so that, in good time before 31st March, 1998, the 1998
         Framework Agreement will contain all text necessary to be included in
         this Agreement in order to implement the 1998 Programme.
         Notwithstanding the Agreement of Pool Members or the Executive
         Committee to the inclusion of such principles and/or text in the 1998
         Framework Agreement, it is agreed by the Parties and Meter Operator
         Parties that no part of the 1998 Framework Agreement shall have effect
         or shall alter, amend or replace any part of this Agreement until
         included in this Agreement by way of a supplemental agreement hereto
         and the process in this Clause 1.8 shall not bind or commit any Party
         or Meter Operator Party or otherwise affect in any way the rights and
         discretions of any Party or Meter Operator Party to withhold or qualify
         its agreement to any supplemental agreement to this Agreement.

                  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

                          Clause 3.6 shall apply.

                  (b)     If the determination is to the effect that the New

                          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).

                  reasonably require, change the capacity(ies) in which it
                  participates as a Party.

               (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,

     Committee's  opinion,  is likely to be the Works Programme Manager or where
     the Works Programme  involves changes to the Specification or the Software,
     be prepared in consultation with the Settlement System Administrator).

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
         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 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 and the Director.

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 all Works Programmes shall be
         project managed by the Settlement System Administrator or (if the
         Settlement System Administrator is unable or unwilling so to project
         manage) such other person as the Executive Committee shall nominate
         (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.

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.

                  Clause, the Director shall have regard to the modifications
                  specified in the report. Further, the 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

                    (c)  specifying the period (not being less than 28 days from
                         the date of  publication  of the notice)  within  which
                         representations  or  objections  with  respect  to  the
                         proposed modifications may be made,

                  and shall consider any representations or objections from any
person which are duly made and not withdrawn.

         5.16.4   A notice under Clause 5.16.3 shall be given:-

                  (a)     by publishing the notice in such manner as the
                          Director considers appropriate for the purpose of
                          bringing the matters to which the notice relates to
                          the attention of persons likely to be affected by the
                          making of the modifications; and

                  (b) by serving a copy of the notice on each Party, the
Executive Committee and the Pool Auditor.

         5.16.5   After considering any representations or objections which are
                  duly made and not withdrawn pursuant to Clause 5.16.3, the
                  Director may by notice published as provided in Clause
                  5.16.4(a) and served on those referred to in Clause 5.16.4(b)
                  specify the modifications to this Agreement which he requires
                  to be made and the date upon which such modifications are to
                  take effect and each of the Parties undertakes with each other
                  of the Parties promptly to take all such steps as may be
                  necessary to give full force and effect to the modifications
                  so required. Any costs incurred by the Settlement System
                  Administrator in giving effect to such modifications shall be
                  recovered in accordance with the Charging Procedure.

                  between certain designated persons and those persons agree in
                  writing the amendment to be made, then the SSA Arrangements,
                  the Menu of Prices or, as the case may be, the Variation Menus
                  (or the relevant one or part thereof) shall be so amended
                  without the need for any other Party to execute or deliver any
                  amending or confirmatory document and each Party hereby
                  consents to such amendments being made in such a manner and
                  undertakes not to withdraw that consent.

         6.7.3 In the following cases the amendment procedure set out in Clause
6.7.2 shall itself be modified as hereinafter provided:-

          (a)  if Schedule 4 refers to "formal  documentation"  being  agreed to
               give effect to the amendment,  an amending  agreement executed by
               all Parties shall be required;

          (b)  if the consent of a particular  person is required to be obtained
               under Clauses 6.1 to 6.6  (inclusive),  the  amendment  shall not
               take effect until that consent has been obtained.

         6.7.4    Subject to:-

          (a)  any consent of a particular  person required to be obtained under
               Clauses 6.1 to 6.6 (inclusive) being obtained;

          (b)  the requirements of Clauses 6.7.5 and 13.2,

                  and save as provided otherwise in this Agreement, any
                  amendment to or variation of this Agreement shall be effective
                  if approved by Pool Members in general meeting pursuant to
                  Clause 13.1 or 13.2 and all Parties agree promptly to execute
                  and deliver all agreements and other documentation and to do
                  all such other acts, matters and things as may be necessary to
                  give effect to such amendment or variation.

          6.7.5 Where any change is proposed to be made to this Agreement which,
               if made:-

                  (a) would introduce provisions dealing with matters not then
dealt with in or expressly contemplated by this Agreement; and

                  (b)     would in any material respect directly affect the
                          rights, benefits, duties, responsibilities,
                          liabilities and/or obligations under this Agreement of
                          the Settlement System Administrator, the Grid
                          Operator, the Ancillary Services Provider and/or any
                          Externally Interconnected Party,

                  such change shall not be made without the prior written
                  consent of the relevant one of them (in each case not to be
                  unreasonably withheld or delayed) provided that the reference
                  to the Grid Operator in this Clause 6.7.5 shall be construed
                  as if it was a reference to such term prior to the creation of
                  Meter Operator Parties and the associated amendments to this
                  Agreement, but this shall be without limitation to any right
                  to consent to any amendment or variation of this Agreement
                  under this Clause 6.7.5.

         Inconsistencies and Conflicts

          6.8  Internal inconsistencies  and  conflicts:  In the  event  of any
               inconsistency or conflict:-

         6.8.1 the Pool Rules 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; and

         6.8.3    the Specification shall prevail over the Software,

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

6.9      External inconsistencies and conflicts:

         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

                  (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).

                  several and a Pool Member shall not be responsible for the

                  obligations under this Agreement shall not relieve any other
                  Pool Member of all or any of its obligations hereunder.

                  or any of such obligations of the Indemnifying Pool Member.

                  date of its admission as a Party and, subject as aforesaid,
                  such person shall not be required to fulfil any further or
                  other Pool Membership Conditions introduced after such date
                  unless the applicant notifies the Executive Committee in

                  admission as a Pool Member that it wishes such further or

                  accordance with that Clause.

         9.4.2    Extraordinary general meetings shall be convened:-

          (a)  by the Secretary on the  instructions of the Executive  Committee
               or of any one or more Committee  Members pursuant to Clause 13.4;
               or

          (b)  by the  Executive  Committee,  forthwith  upon  receipt of a Pool
               Members'  requisition being a requisition of Pool Members holding
               together at the date of the deposit of the  requisition  not less
               than  two per  cent.  of the  Total  Weighted  Votes  of all Pool
               Members; or

          (c)  by the Secretary on the instructions of the Pool 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
                  requisitionists and deposited at the office 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 convened by the Executive Committee.

          9.5  Notice of general  meetings:  Any notice  convening  any  general
               meeting of Pool Members shall be exclusive of the day on which it
               is served  or deemed to be served  and of the day for which it is
               given,  and shall specify the place,  the day and the hour of the
               meeting and the general  nature of the  business of such  meeting
               and shall be given to all 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 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.

9.6      Annual conference:

         9.6.1    In each year, on a date falling as near as practicable to, but
                  in any event not later than, eight months after the

                  Pool Members shall be convened and held which shall not be the
                  annual general meeting but which may (but need not) be

               by  reason  of  its  Pool  Membership  (its  "Membership  Vote").

          11.2 Weighted Votes:  Subject as provided in the following  provisions
               of this Clause 11, in respect of any Quarter:-

          11.2.1 each Pool Member which is a Generator shall be entitled in that
               capacity to one vote (each such vote a "Generator Weighted Vote")
               for each GWh of Genset  Metered  Generation  of all its Allocated
               Generating Units for all Settlement  Periods falling in the Votes
               Calculation  Period relative to such Quarter,  as determined from
               the final run of Settlement for each such  Settlement  Period and
               with the  number  of GWh  being  rounded  up or down  (0.5  being
               rounded upwards) to the nearest whole number;

         11.2.2   the number of votes (each a "Supplier Weighted Vote") to which
                  a Pool Member which is a Supplier shall be entitled in that
                  capacity shall be calculated in accordance with the following
                  formula:-

                                            GWV  x    SV
                                                     (SIGMA) SV

                          where:

                          SV       is equal to the total GWh of Consumer Metered
                                   Demand taken by the relevant Pool Member in
                                   all Settlement Periods falling in the Votes
                                   Calculation Period relative to the relevant
                                   Quarter, as determined from the final run of
                                   Settlement for each such Settlement Period
                                   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 the relevant Quarter; and

                    (SIGMA) means  summed over the total SV of all Pool  Members
                         for the relevant Quarter,

                  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 Quarter pursuant to
                           Clause 11.3.2. If at any time during such Quarter 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 Quarter 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 Quarter, adjust as
                           between the Pool Members involved in such transfer,
                           the number of Points and/or Weighted Votes to which
                           they in their capacities as Suppliers are entitled in
                           respect of the remaining part of that Quarter and/or
                           one or both of the two immediately succeeding
                           Quarters 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.

                    11.3 Calculation of Weighted  Votes:  Subject as provided in
                         the following provisions of this Clause 11:-

         11.3.1   New Pool Members:

                  (a)     until the third Quarter Day next falling after the
                          date of its admission as a Pool Member, any Party who
                          is admitted as a Pool Member pursuant to Clause 8.2

                         Weighted Vote, depending on the capacity(ies) in which
                         it is participating as a Pool Member; and

         11.3.4   Additional capacity: for the purposes of this Clause 11 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 and until the third Quarter Day next
                  falling after the date such Pool Member's application to the

                          Votes in accordance with Clause 11.4.5, such Pool
                          Member shall have as nearly as practicable (but not in
                          excess of) 15 per cent. of the Total Weighted Votes.
                          The Redistributed Votes shall:-

                  Votes, to the largest Supplier in terms of Consumer Metered
                  Demand for the relevant Quarter, 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

         be deemed to warrant to all other Pool Members that all such details
         are true and accurate in all material respects as at the date they are

                          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 System Administrator and
                          the Pool Funds Administrator of receipt of such
                          application. At the same time as the Executive
                          Committee shall notify all such other Pool Members,
                          each Externally Interconnected Party (not being a Pool
                          Member), the Pool Chairman, the Settlement System
                          Administrator and the Pool Funds Administrator of such
                          receipt, the Executive Committee shall send each of
                          them 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.

14.      ESTABLISHMENT OF THE EXECUTIVE COMMITTEE

          Establishment:   The  Pool  Members  hereby  establish  the  Executive

15.1     Number of the Committee Members: The maximum number of Committee
         Members shall not at any time exceed twelve or such lesser number
         (subject to a minimum of six) as Pool Members may decide in general

         Pool Members. Any such lesser number so decided upon prior to an annual
         general meeting of Pool Members shall be the maximum number of
         Committee Members during the entire term of office (according to Clause
         15.4) of those Committee Members elected at that annual general meeting

         On the expiry of that term of office, the maximum number of Committee
         Members shall be twelve unless a lesser number shall have been decided
         upon in accordance with the procedures set out in this Clause 15.1.

15.2 Maximum  number of Committee  Members  fewer than  twelve:  If Pool Members
     decide on a maximum  number  of  Committee  Members  fewer  than  twelve in

                  with the provisions of Clause 15.5 shall be two fewer than the
                  agreed maximum number of Committee Members and the number of
                  Committee Members to be appointed in accordance with Clause
                  15.6 shall be two; and

         15.2.2   The references to "ten" and its derivatives in Clauses
                  15.5.3(g) and 15.5.3(i) shall be substituted by the number

                  agreed by Pool Members and the references to "nine" and
                  "eleven" (and their respective derivatives) in Clause
                  15.5.3(i) shall be correspondingly altered.

15.3 Appointment and Removal: As from 1st April, 1997 and subject as provided in
     Clauses 15.2 and 15.8, ten Committee Members shall be appointed and removed
     in  accordance  with the  provisions  of  Clauses  15.5 and  15.10  and two
     Committee  Members shall be appointed  and removed in  accordance  with the
     provisions of Clauses 15.6 and 15.10.

         Committee Members shall be from 1st April in the year of appointment to
         31st March in the next following year provided that, if the meeting at
         which any Committee Member is appointed is held after 1st April, his
         term of office shall commence from the time of his appointment. A
         Committee Member whose term of office has expired or is to expire shall
         be eligible for re-election.

15.5 MP Committee  Member  election  procedure:  The  procedures set out in this
     Clause 15.5 shall apply to the election of those Committee  Members who are
     not RS Committee Members ("MP Committee Members"):- --------------------

         15.5.1   Each MP 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 any MP Committee Members at
                  such meeting, no later than 15 days before an extraordinary
                  general meeting convened for such purpose to propose, one
                  individual (an "MP Nominee") to be an MP Committee Member. The
                  MP 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 MP Nominee stating
                  that he is aware of the proposal and would be prepared to
                  serve as a Committee Member if elected.

         15.5.2   No later than 10 days before the date of the annual general
                  meeting (or, as the case may be, extraordinary general
                  meeting) the Executive Committee shall circulate (or cause to
                  be circulated) to all Pool Members and the Director a list of
                  all the names of the MP Nominees and of the Pool Members who
                  proposed them (the "MP Nominee List"). The MP Nominee List
                  shall also be circulated at the annual general meeting or, as
                  the case may be, extraordinary general meeting to all Pool
                  Members present in person; and

         15.5.3   At the annual general meeting or extraordinary general meeting
                  (as the case may be) of Pool Members held to appoint Committee
                  Members the following procedures shall be applied in
                  sequence:-

                  (a)     each MP Pool Member shall be given a voting paper (in
                          this Clause 15.5, a "Voting Paper") with the name of
                          every MP Nominee who appears on the MP Nominee List;

                  (b)     subject to paragraphs (c) and (d) below, an MP Pool
                          Member shall rank each MP Nominee on its Voting Paper
                          in order of preference by marking the MP Nominee which
                          is its first choice for membership of the Executive
                          Committee (its "Preferred MP Nominee") with the number
                          "1" and continuing numbering sequentially in order of
                          preference until it is indifferent as to the
                          preference it accords to any remaining MP Nominees;

                  (c)     if an MP Pool Member has proposed an MP Nominee in
                          accordance with Clause 15.5.1, then such MP Pool
                          Member must choose that MP Nominee as its Preferred MP
                          Nominee;

                  (d)  all MP Pool  Members  that are members of the same Pool
                         Member's  Group  shall be  obliged  to rank the same MP
                         Nominees in the same order of preference;

                  (e)     the Moderator shall collect in all Voting Papers and
                          for each Preferred MP Nominee shall calculate the
                          number of Weighted Votes cast by those MP Pool Members
                          in his favour and for this purpose each MP Pool Member
                          shall be deemed to have cast all its Weighted Votes in
                          favour of its Preferred MP Nominee;

                  (f)     the Moderator shall prepare a list (the "MP Preference
                          List") ranking the Preferred MP Nominees in order
                          according to the number of Weighted Votes cast for
                          each such Preferred MP Nominee, with the Preferred MP
                          Nominee with the most number of Weighted Votes being
                          at the head of the list;

                  (g)     when there are more than ten MP Nominees on the MP
                          Preference List then, if the MP Nominee ranked tenth
                          on the MP Preference List has more Weighted Votes cast
                          in his favour than the sum of all Weighted Votes cast
                          for all those MP Nominees ranked below him on the MP
                          Preference List, those MP Nominees ranked first to
                          tenth on the MP Preference List shall be elected as
                          Committee Members and the voting procedure in this
                          Clause 15.5.3 shall terminate;

                    (h)  if  the   condition  in  paragraph  (g)  above  is  not
                         satisfied,  the MP Nominee  whose name  appears last on
                         the MP  Preference  List shall be  removed  from the MP
                         Preference  List and shall take no further  part in the
                         election  process for the MP Committee  Members and the
                         Moderator  shall  transfer  the  Weighted  Votes of all
                         those MP Pool  Members who voted for that MP Nominee to
                         the  MP  Nominee(s)  who  is  their  respective  second
                         preference.  The Moderator shall then prepare a revised
                         MP Preference  List to which  paragraph (g) above shall
                         be applied and the procedure set out in this  paragraph
                         (h)  shall be  repeated  as  often as may be  necessary
                         until the condition in paragraph (g) above is satisfied
                         (on each  occasion  the MP Nominee  whose name  appears
                         last on the MP  Preference  List being  removed from it
                         and the Moderator  transferring  the Weighted  Votes of
                         all  those  MP  Pool  Members  attributable  to that MP
                         Nominee  to  the  MP  Nominee(s)   who  is  their  next
                         respective preference); and

                          (i)      if the provisions of paragraph (h) above have
                                   been followed with the result that only
                                   eleven MP Nominees appear on the MP
                                   Preference List, and if the MP Nominee ranked
                                   tenth has more Weighted Votes cast in his
                                   favour than the MP Nominee ranked eleventh,
                                   then those MP Nominees ranked first to tenth
                                   on the MP Preference List shall be elected as
                                   Committee Members. If, however, the Weighted
                                   Votes cast in favour of the MP Nominees
                                   ranked tenth and eleventh on the MP
                                   Preference List are equal, then those MP
                                   Nominees ranked first to ninth on the MP
                                   Preference List shall be elected as Committee
                                   Members and the selection of the tenth
                                   Committee Member from the tenth and eleventh
                                   MP Nominee on the MP Preference List shall be
                                   decided by the drawing of lots in a manner to
                                   be determined by the Pool Chairman.

     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 SG Committee Member or IS
                  Committee Member;

         15.6.2   No later than 10 days before the annual general meeting (or,
                  as the case may be, the extraordinary general meeting) the
                  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
                  object to any RS Nominee by notice to the Executive 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;

         15.6.4   At the annual general meeting or extraordinary general meeting
                  (as the case may be) of Pool Members the following procedures
                  shall be applied (subject to Clause 15.6.5) in sequence first
                  for the election of the SG Committee Member and, secondly, for
                  the election of the IS Committee Member immediately following
                  the conclusion of the election procedures for the MP Committee
                  Members in Clause 15.5:-

                  (a)     each RS Pool Member shall be given a voting paper (in
                          this Clause 15.6, a "Voting Paper") with the name of
                          every RS Nominee who appears on the RS Nominee List
                          (amended, if appropriate, in accordance with Clause
                          15.6.2);

                  (b)     SG Pool Members shall be entitled to vote only for RS
                          Nominees nominated by SG Pool Members and whose names
                          appear on the Voting Paper ("SG Nominees");

                  (c)     IS Pool Members shall be entitled to vote only for RS
                          Nominees nominated by IS Pool Members and whose names
                          appear on the Voting Paper ("IS Nominees");

                  (d)     in the case of the election of the SG Committee
                          Member, each SG Pool Member shall rank each SG Nominee
                          on its Voting Paper in order of preference by marking
                          the SG Nominee which is its first choice for
                          membership of the Executive Committee (its "Preferred
                          SG Nominee") with the number "1" and continuing
                          numbering sequentially in order of preference until it
                          is indifferent as to the preference it accords to any
                          remaining SG Nominees;

                  (e)     in the case of the election of the IS Committee
                          Member, each IS Pool Member shall rank each IS Nominee
                          on its Voting Paper in order of preference by marking
                          the IS Nominee which is its first choice for
                          membership of the Executive Committee (its "Preferred
                          IS Nominee") with the number "1" and continuing
                          numbering sequentially in order of preference until it
                          is indifferent as to the preference it accords to any
                          remaining IS Nominees. Preferred SG Nominees and
                          Preferred IS Nominees are, for the purposes of this
                          Clause 15.6, known as the "Preferred RS Nominees";

                  (f)     if a RS Pool Member has proposed a SG Nominee or an IS
                          Nominee in accordance with Clause 15.6.1, then such RS
                          Pool Member must choose that SG Nominee or (as the
                          case may be) IS Nominee as its Preferred RS Nominee;

                  (g)     the Moderator shall collect in all Voting Papers and
                          for each SG Nominee and each IS Nominee shall
                          calculate the number of Weighted Votes cast by RS Pool
                          Members in his favour and for this purpose each RS
                          Pool Member shall be deemed to have cast all its
                          Weighted Votes in favour of its Preferred RS Nominee;

                  (h)     the Moderator shall prepare a list (the "SG Preference
                          List") ranking the Preferred SG Nominees in order
                          according to the number of Weighted Votes cast for
                          each such Preferred SG Nominee, with the Preferred SG
                          Nominee with the most number of Weighted Votes being
                          at the head of the list;

                  (i)     the Moderator shall prepare a list (the "IS Preference
                          List") ranking the Preferred IS Nominees in order
                          according to the number of Weighted Votes cast for
                          each such Preferred IS Nominee, with the Preferred IS
                          Nominee with the most number of Weighted Votes being
                          at the head of the list;

                  (j)     if the RS Nominee ranked first on the SG Preference
                          List or (as the case may be) IS Preference List has
                          more Weighted Votes cast in his favour than the sum of
                          all Weighted Votes cast for all those RS Nominees
                          ranked below him on the same list, the RS Nominee
                          ranked first on the relevant list shall be elected as
                          the SG Committee Member or (as the case may be) IS
                          Committee Member and the voting procedure in this
                          Clause 15.6.4 shall terminate; and

                    (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  Nominee to  the RS
                         Nominee(s) who is their 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 be  repeated as often as may be  necessary  until
                         the  condition in  paragraph (j) above is satisfied in
                         relation to the relevant  list (on each occasion the RS
                         Nominee  whose name appears  last on the SG  Preference
                         List or (as the case may be) IS  Preference  List being
                         removed  from it and  the  Moderator  transferring  the
                         Weighted   Votes   of  all   those   RS  Pool   Members
                         attributable  to that RS Nominee  to the RS  Nominee(s)
                         who is their next respective preference); 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    Removal of Committee Members:

         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.

         15.10.2  A separate general meeting of those Pool Members entitled to
                  vote may be convened for the purpose of removing a Committee
                  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; or

  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 of the
          Outgoing  Committee  Member in an election  pursuant to Clause 15.5 or
          15.6 and who were, at the time of his vacation of office,  represented
          by him pursuant to Clause 23.6.1 or 23.6.2; and

     (b)  only those  persons who have become Pool  Members in the period of the
          Outgoing  Committee  Member's term of office and who were, at the time
          of his  vacation  of office,  represented  by him  pursuant  to Clause
          23.6.4

         may take part in the election of a replacement Committee Member
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,

                                   an annual general meeting or (as the case may
                                   be) an extraordinary general meeting of Pool

                  collection costs are incurred by Second Tier Agents or the
                  Settlement System Administrator shall be used in determining
                  the number of Second Tier Systems.

34A.6    If in respect of any Specified Accounting Period (other than the one
         beginning on 1st April, 1997) the aggregate of all second tier system
         charges payable pursuant to Sections 34A.5(a), 34A.5(b) and 34A.5(c)
         and received by the Settlement System Administrator is less than or (as
         the case may be) more than the Total Second Tier System Charges for
         such Specified Accounting Period the deficit or (as the case may be)
         the surplus shall be carried forward to the immediately succeeding
         Specified Accounting Period and shall be included in the calculation of
         the Total Second Tier System Charges therefor.

         that the aggregate of all second tier system charges payable pursuant
         to Sections 34A.5(a), 34A.5(b) and 34A.5(c) and received by the

                          communication or document reasonably believed by it to

                          reliance.


         50.2.2   Compliance with the Director's directions: No liability
                  whatsoever shall attach to the Grid Operator as a result of
                  due compliance by it with any directions and instructions of

                  or the Chief Executive, the Grid Operator 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

                  Members, be deemed to have the express authority of, and shall
                  be binding without reservation upon, all Pool Members.

         50.2.5   Authority of Pool Members: The Grid Operator shall not be
                  bound to act in accordance with the directions or instructions
                  of the Pool Members unless the Pool Members act through the
                  Executive Committee.

         50.2.6   General Meetings: The Grid Operator shall not be obliged to
                  take any steps to ascertain whether any resolution of Pool

                  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
                  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

                  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
                  if:-


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


                  (b)     the Grid Operator has reasonable grounds for believing
                          that it would so breach any of such obligations and
                          has consulted the Director and:-


               (i)  the Director has not indicated that in his view it would not
                    involve any such breach; or


                          (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 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.

                    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 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 69. 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
         Suppliers 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 Suppliers 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 amounts in its
                    Ancillary Service charge to Suppliers 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, without prejudice to the Ancillary Services Provider's
                    right to recover such lost opportunity costs from Suppliers,
                    if requested by the Suppliers shall recover such lost
                    opportunity costs over such a period as may be agreed
                    between the Ancillary Services Provider and the Suppliers
                    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

                                   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

                                   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.

         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

                          the Ancillary Services Provider is required to obtain

                          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

                          Provider shall not be bound to act in accordance with

                          unless the Pool Members act through the Executive

         51.10.6          General Meetings: The Ancillary Services Provider
                          shall not be obliged to take any steps to ascertain

                          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 sub-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 if:-

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

                          (b)      the Ancillary Services Provider has
                                   reasonable grounds for believing that it
                                   would so breach any of such obligations and
                                   has consulted the Director and:-



               (i)  the Director has not indicated that in his view it would not
                    involve any such breach; or



                                   (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
                                            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.



                    51.11Suppliers'  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
                         majority vote of the Suppliers'  representatives on the
                         Executive Committee.

         Agreement which related to UMIS2 (as was therein defined) shall
         prejudice any Consumer's (as defined in the Pool Rules) or the Grid
         Operator's (acting through its agent the Ancillary Services Provider)
         accrued rights and liabilities under each of UMIS2 and/or TSS at the
         date of such termination or expiry which accrued rights shall include,
         for the avoidance of doubt, the ability to adjust sums calculated under
         UMIS2 and/or TSS in respect of disputes arising after such termination
         or expiry in respect of periods falling before such termination or
         expiry.

                  Transmission Services Scheme 2 at the date of such termination
                  or expiry, which accrued rights shall, for the avoidance of
                  doubt, include the ability to adjust sums calculated under the

52.      SETTLEMENT RE-RUNS

          52.1 Re-runs:  The  Parties  acknowledge  and agree  that there may be
               occasions  following any final run of Settlement  (as referred to
               in  paragraph  D(3) of the  Preamble  to  Schedule  9) when it is
               necessary  in respect of a  Settlement  Day (or part  thereof) to
               re-determine the trades of electricity pursuant to this Agreement
               and the provision of Ancillary  Services (whether to take account
               of  oversight  or error,  malfunction  of the  Settlement  System
               operation in accordance with Grid Operator Despatch  instructions
               issued under emergency  circumstances,  award of an arbitrator(s)
               pursuant to Clause 83, court order or otherwise  howsoever).  The
               Executive  Committee,  in consultation with the Settlement System
               Administrator,  the Pool Funds Administrator and the Pool Auditor
               and, where  appropriate,  the Ancillary Services Provider and the
               Grid Operator,  shall decide how such  re-determination  is to be
               effected, the re-allocation of moneys and the period of time over
               which any such  re-allocation is to take place, any such decision
               to take account and give effect, as nearly as practicable, to the
               principles and procedures set out in this Agreement  (and,  where
               relevant, the award of the said arbitrator(s) or court order). In
               particular,  but  without  prejudice  to  the  generality  of the
               foregoing,  the  Executive  Committee  may require  following any
               relevant  final run of  Settlement  (and shall take due notice of
               any  request  from the  Ancillary  Services  Provider or the Grid
               Operator to this effect) the Settlement  System  Administrator to
               re-run,  and the Settlement  System  Administrator  shall re-run,
               Settlement  in respect of any  Settlement  Day (or relevant  part
               thereof) using the software and data  originally  used in respect
               of such  Settlement Day (or relevant part thereof) but subject to
               such changes,  amendments or additional inputs as may be required
               by the Executive  Committee (in  consultation  with the Ancillary
               Services Provider, the Grid Operator or any other relevant party)
               or by (as the case may be) such  arbitrator(s) or court. Any such
               re-run  shall  hereafter  in this  Clause 52 be  referred to as a
               "Re-run".

52.2     Timing: The Settlement System Administrator shall arrange for any
         Re-run to be carried out as soon as is reasonably practicable following
         request by the Executive Committee subject to the availability of
         computer time, compatible software, appropriate data and other
         resources.

52.3     Ancillary Services Provider: The Ancillary Services Provider shall have
         the right to incorporate any delayed or disputed amount in respect of
         the provision of Ancillary Services into Settlement without requiring a
         Re-run.

52.4     Notification: The Executive Committee shall promptly notify each Party,
         the Pool Auditor and the Director of each occasion on which it requires
         the Settlement System Administrator to carry out any Re-run, the
         reasons for such requirement, the timing thereof and the period to be
         covered thereby and shall provide each Party with such information
         about any Re-run as is relevant to such Party and shall provide the
         Pool Auditor and the Director with full details of any Re-run.

52.5     Proviso: The foregoing provisions of this Clause 52 are subject to the
         proviso that no Re-run shall be carried out, and neither the Executive
         Committee nor any Party shall be entitled to require that a Re-run be
         carried out, in respect of a Settlement Day or any part thereof after
         the first anniversary of such Settlement Day, but so that this proviso
         shall not restrict the right of any Party to claim or recover any
         moneys properly due and owing to it under this Agreement.

          53.4 Notification (1): If the Executive Committee  determines that, in
               respect of any Centrally  Despatched  Generating Unit, the Scheme
               Admission  Conditions have been met it shall forthwith and in any
               event  within  40 days  after  receipt  of the  Scheme  Admission

         54.1       No person has an Accountable Interest in the Centrally
                    Despatched Generating Unit which is the subject of the
                    Scheme Admission Application which, when added to the
                    Accountable Interests of that person in other Generating

                    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

               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.

          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 the  Scheme  during any period  referred  to in Clause  50.4
               applicable to that Scheme Genset.

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 to the Pool Funds Administrator:-

         58.1.1     any Fuel Security Payment specified in that Payment
                    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.

58.2     Clarification: If the Pool Funds Administrator considers either that
         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.

58.3     Failure to specify or clarify: If a Payment Instruction fails to
         specify the basis upon which the Fuel Security Payment or a Fuel
         Security Reimbursement specified in that Payment Instruction must be
         paid or if the Director fails to clarify any matter notified to it in
         accordance with Clause 58.2 within ten Business Days of such
         notification then the Pool Funds Administrator shall arrange for the
         relevant payment to be made on such basis as the Executive Committee

          60.4.2 All  Metering  Systems at the site of a  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 accompanied by payment of such fees (if any) as
                    is prescribed by the relevant Agreed Procedures. Where any

         60.4.4     The Registrant in respect of a 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
                    Metering System.

         60.4.5     If a person which is an Operator in respect of any 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
                    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

                    the decision of the Executive Committee, the matter may be
                    referred by such Party to arbitration in accordance with
                    Clause 83.

         60.11.3    It is hereby expressly acknowledged and agreed by the
                    Parties that the resolution of any dispute referred to in
                    Clause 60.11.1 or 60.11.2 shall in all cases be without
                    prejudice to the bringing or pursuing of any claim, by or
                    against, or the resolving of any issue between any one or

          may  incur as a result of the  failure  of any Pool  Member,  the Grid
          Operator  or the  Ancillary  Services  Provider  (as the  case may be)
          properly to account to H.M. Customs & Excise for all amounts of United

                    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
                    incur pursuant to paragraph 63.3.1.

         Arrangements for the purpose or to such other address, telex number or
         facsimile number as the Secretary may from time to time specify by
         notice given in accordance with this Clause 75 to the Parties.

75.3     Deemed receipt: Save as otherwise expressly provided in the SSA
         Arrangements, any notice or other communication to be given by any
         Party to any other Party under, or in connection with the matters
         contemplated by, the SSA Arrangements shall be in writing and shall be
         given by letter delivered by hand or sent by first class prepaid post
         (airmail if overseas) or telex or facsimile, and shall be deemed to

         75.3.2     in the case of first class prepaid post, on the second day

                    posting; or

         75.3.3     in the case of telex, on the transmission of the automatic
                    answer-back of the addressee (where such transmission occurs

         75.3.4     in the case of facsimile, on acknowledgement by the

                    acknowledgement) and in any other case on the day following
                    the day of acknowledgement.

76.      ASSIGNMENT

         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
         SSA Arrangements provided that any Party may assign by way of security
         only all or any of its rights over receivables arising under the SSA
         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 delivered shall constitute an original, but all the counterparts
         shall together constitute but one and the same instrument.

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 SSA 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 SSA
         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 SSA Arrangements (other than any
         such rights or remedies provided under section 58 of the Act or any
         directions (if any) issued thereunder), including without limitation
         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 SSA 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 SSA 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 SSA 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
                  SSA Arrangements and/or the inclusion of any provision in the
                  SSA 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 SSA 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 SSA Arrangements contain or expressly refer to the entire agreement
         between the Parties with respect to the subject matter hereof 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 SSA 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 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 SSA 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 provisions of the Arbitration Acts
         1950 (notwithstanding anything in section 34 thereof) to 1979 shall
         apply to any such arbitration wherever the same or any part of it shall
         be conducted.

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 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.

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

IN WITNESS whereof this Agreement has been duly executed the day and year first
above written

         System Administrator shall exercise that degree of care, diligence,

         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

         the SSA Arrangements other than for loss directly 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:-

         employees or agents shall in any circumstances whatsoever be liable to

         4.8  Saving:  For the  avoidance  of doubt,  nothing in this Section 4

                  undertakings is held to be against the public interest or
                  unlawful or in any way an unlawful restraint of trade, the
                  remaining undertakings shall continue to bind the relevant
                  Party.

         5.4.2    Breach by ESIS of its obligations under paragraph 5.4.1(a)
                  above shall not entitle the Executive Committee to terminate
                  the appointment of ESIS as Settlement System Administrator
                  under this Agreement and breach by a Pool Member of its
                  obligations under paragraph 5.4.1(b) above shall not
                  constitute a breach by a Pool Member of its obligations for
                  the purposes of Section 28, but in each case shall only
                  entitle such other party to claim damages or to bring
                  proceedings for an injunction.

                          inconsistencies therein.

7.       PERFORMANCE OF DUTIES

7.1      Independent contractor: In carrying out its duties and responsibilities
         under the SSA Arrangements, the Settlement System Administrator shall
         act as an independent contractor 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.

7.2      Delegation:

         7.2.1    Subject as provided in paragraphs 7.2.2 and 7.2.3, the
                  Settlement System Administrator may delegate the performance
                  of all or any of its duties and responsibilities under the SSA
                  Arrangements to agents or contractors.

         7.2.2    The Settlement System Administrator shall be entitled to
                  delegate the performance of all or any of its duties and
                  responsibilities under the SSA Arrangements provided that they
                  are not duties or responsibilities which are in respect of any
                  significant matter (unless the prior written approval of the
                  Executive Committee under paragraph 7.2.3 has been given).

         7.2.3    In giving any such approval as is referred to in paragraph
                  7.2.2 the Executive Committee shall specify the particular
                  duties and responsibilities which may be delegated and to whom
                  and for what period. On receipt of such approval the
                  Settlement System Administrator may delegate its duties and
                  responsibilities only to the extent of the terms of such
                  approval.

         7.2.4    As between the Settlement System Administrator and the other
                  Parties, no delegation pursuant to this sub-section 7.2 or
                  pursuant to Clause 60.15 nor the terms or conditions of any
                  contract pursuant to which any such delegation is effected
                  shall relieve the Settlement System Administrator of any of
                  its duties or responsibilities under the SSA Arrangements. The
                  Settlement System Administrator shall at all times properly
                  supervise the performance of all such delegates.

         7.2.5For the avoidance of doubt, the term "delegation" as used in this
               sub-section 7.2 includes sub-contracting.

8.       RESPONSIBILITY FOR THE SSA SYSTEM

          8.1  The SSA System:  The Settlement System  Administrator  shall have
               control of the running and development of the SSA System, subject
               to the restrictions set out in this Section 8.

8.2      Developed software:

         (a)      In relation to any Software developed by the Settlement System
                  Administrator, the Settlement System Administrator shall
                  procure that all intellectual property rights shall vest in
                  the Settlement System Administrator absolutely. In the case of
                  Software commissioned from third parties or where rights in
                  Software are purchased, the Settlement System Administrator
                  shall procure that all intellectual property rights are
                  transferred to the Settlement System Administrator. Where the
                  Settlement System Administrator customises, or commissions the
                  customisation of, any Software licensed from any third
                  parties, the Settlement System Administrator shall procure
                  that all intellectual property rights shall vest in the
                  Settlement System Administrator.

         (b)      Pool Members confirm and agree (i) that they have no objection
                  to the intellectual property rights referred to in paragraph
                  (a) above being held in this way and (ii) that the Settlement
                  System Administrator shall have the right of use of such
                  intellectual property rights as an absolute owner.

8.3      Licensed software: In respect of any Software not developed internally,
         purchased or commissioned, the Settlement System Administrator shall
         ensure that it has a fully transferable licence to use the 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 fees shall be
         payable in respect of any transfer of the licence to any nominated
         representative of the Executive Committee 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 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.

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      Notification of commercial use: The Settlement System Administrator
         shall promptly notify the Executive Committee if it uses the Software
         for a purpose other than that envisaged under the SSA Arrangements,
         including its sale, licence, development or otherwise being made
         available howsoever to any other person with such details as the
         Executive Committee may reasonably request.

                  translate such Software and other property for any purpose
                  related to the operation of the Settlement System;

         (b)      use all reasonable endeavours to novate, or procure the

                  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,

                  the outgoing Settlement System Administrator and relating to

                  facilities, rights, know-how and transitional assistance which
                  it possesses and which is necessary for such successor to have
                  to operate the 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 as is practical in all the

         remedy or is capable of remedy, but is not remedied within 30 days from
         the date of receipt by the Executive Committee of 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):-

                  date thereof, and the appointment of ESIS as Settlement System
                  Administrator shall terminate on that date and 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); or

         (b)      give notice to all Pool Members, the Executive Committee and
                  the Chief Executive's Office identifying such irremediable
                  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 or a Meter Operator Party, 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.

31.      CONTRACT MANAGEMENT RULES

31.1     Contract Management Rules: The Parties agree that, whilst the Contract
         Management Rules do not constitute or evidence legally binding
         obligations, they are indicative of best practice with respect to
         certain aspects of the day-to-day operation of the SSA Arrangements and
         include practices and procedures which either have been proven or are
         expected to facilitate that day-to-day operation. The Parties agree
         that a failure by a Party to comply with the Contract Management Rules
         shall not of itself constitute a breach of the SSA Arrangements nor
         give rise to any sanction against that Party.

31.2     Amendments to the Contract Management Rules: The Contract Management
         Rules may be amended, modified or varied by agreement between the
         Account Manager and the Contract Manager in accordance with procedures

                  Period referred to in paragraph 32.2.1 above.

         32.2.3   The provisions of this sub-section 32.2 are without prejudice
                  to any other review or revision of the Menus of Prices

                  Schedule or the Appendix hereto.

2.5      Limits on Production Services: There are physical constraints on the
         Settlement System which are recognised through the maxima set out in
         the Menu of Production Services Prices. This Appendix provides in

         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

7.2      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 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 31st
         March, 1999 the Settlement System Administrator shall review the Sole
         Supplier Index in consultation with the Executive Committee to assess
         whether it is appropriate to amend the list of Services which are
         designated as Sole Supplier Services. If as a result of that 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 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 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).

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

1.2      Negotiation: Upon receipt of any such request the Account Manager will
         negotiate in good faith with the Contract Manager to amend in
         accordance with the Change Management Procedure referred to in Service
         Line 12 (Management of Settlement Change) 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:-

          (a)  vary  the  SSA   Arrangements,   the  Settlement  System  or the
               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 shall become a Production Service, a
         Development Service or a Consultancy Service (as appropriate) which may
         then be Ordered.

2.       VARIATION MENUS

2.1      Variation Menus: With effect from the first day of each SSA Accounting
         Period, beginning with the SSA Accounting Period starting in 1995,
         and/or at such other times as may be prescribed in the relevant

                  first day of an SSA Accounting Period, the Settlement System
                  Administrator shall prepare and deliver to the Contract
                  Manager no later than two months before the adjustment is to

          System  Administrator  for such  premises  occupied by the  Settlement
          System  Administrator  as may be agreed from time to time  between the
          Settlement System  Administrator and the Executive Committee (being in
          any event premises occupied by the Settlement System Administrator for
          the  performance  of the  Services),  the Menu of Production  Services
          Prices shall be  automatically  adjusted  with effect from the date on
          which such change takes effect by the fair allocation of the amount of
          such change across the prices for all Continuous  Production  Services
          provided that in the calculation of the change in the aggregate amount
          of rent payable by the Settlement System Administrator any increase in
          the amount of rent payable in respect of any premises  occupied by the
          Settlement  System  Administrator  shall be taken into account only to
          the  extent  that  the  Settlement  System  Administrator  is  able to
          demonstrate to the reasonable  satisfaction of the Executive Committee
          that the rent for the  relevant  premises as so  increased  is no more
          than the open  market  rack rent for those  premises as at the date of
          such increase.

3.2      Mechanics: If there shall be a change in rent as described in
         sub-section 3.1 above, the Settlement System Administrator shall
         prepare and deliver to the Contract Manager a revised Menu of
         Production Services Prices adjusted in accordance with sub-section 3.1
         above together with a report from the Settlement System Administrator's
         auditor confirming that it has reviewed the revised Menu of Production
         Services Prices and that it has been fairly adjusted in accordance with
         sub-section 3.1 above.

4.       VOLUME CHANGES

4.1      Units of Variation: Menus of Prices may provide for units of variation
         and prices per unit of variation to Services in which case the units of
         variation can be Ordered at the price per unit stated upon the
         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
         shall be treated as new Services and Services required below any such
         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.

5.       STANDING CHARGES

         The standing charges referred to in sub-sections 4.1 and 5.1 of Part G
         shall be varied automatically at the times and in the manner provided
         in the relevant Service Line.

6.       MONTHLY MINIMUM MANPOWER CHARGE COMMITMENT

     6.1  Monthly Minimum Manpower Charge Commitment: For each Service Line, the
          Monthly  Minimum  Manpower  Charge  Commitment  for any month shall be
          determined in accordance with the following formula:-

         MMMCC    =        C
                                   12

         where:-

     MMMCCis the Monthly  Minimum  Manpower  Charge  Commitment for the month in
          question (expressed in pounds sterling);

          A    is the  minimum  number of  man-days  per  annum  for each  skill
               category as shown in the minimum  manpower  column in the current
               Menu of  Consultancy  Services  Prices  and the  current  Menu of
               Development Services Prices;

          B    is the price at current FSC Rates for the same skill  category as
               shown in the Menu of Manpower Prices; and

          C    is the  aggregate of the sum of (A x B) for all skill  categories
               as so shown.

6.2      Reconciliation: Within 15 working days after (x) the first six month
         period in an SSA Accounting Period and (y) the end of an SSA Accounting
         Period (each an "MMMCC Calculation Period") the Settlement System
         Administrator shall for each Service Line calculate and notify the
         Contract Manager of:-

         (a) the aggregate Monthly Minimum Manpower Charge Commitment for the
six months falling in the MMMCC Calculation Period ("Sum A");

         (b)      the aggregate charges for manpower Ordered for the six months
                  falling in the MMMCC Calculation Period in connection with
                  Consultancy Services and Development Services ("Sum B"); and

         (c)      the aggregate amount invoiced to Pool Members in the MMMCC
                  Calculation Period being for each month the greater of the
                  Monthly Minimum Manpower Charge Commitment or the charge for
                  manpower Ordered ("Sum C").

         The relevant adjustment for the purposes of sub-section 10.2 of Part G
shall always be zero or a credit to Pool Members, shall arise either:-

          (i)  where Sum A is greater  than or equal to Sum B in which event the
               credit  shall be such  amount as is equal to the  amount by which
               Sum C exceeds Sum A; or

          (ii) where Sum A is less than Sum B in which event the credit shall be
               such  amount as is equal to the amount by which Sum C exceeds Sum
               B.

7.       MARKET TESTS AND PERFORMANCE IMPROVEMENT PROGRAMMES

         The Menus of Prices shall be further adjusted following a market test
         or the implementation of a Performance Improvement Programme in
         accordance with the agreement (if any) reached between the Settlement
         System Administrator and the Executive Committee.

8.       INCONSISTENCIES IN THE SSA ARRANGEMENTS

         If there is a change or variation to any part of the SSA Arrangements
         which creates an inconsistency in the obligations to be discharged by
         the Settlement System Administrator under the SSA Arrangements, the
         Settlement System Administrator may request the Contract Manager (in
         the case of a Service Line) or Pool Members, through the Executive
         Committee (in the case of any other part of the SSA Arrangements) to
         make such amendments to the SSA Arrangements as it considers necessary
         to remove such inconsistency and the Contract Manager or, as the case
         may be, the Executive Committee shall act accordingly to make such
         amendments as soon as reasonably possible.

               or potential breach,  the Director would not be minded to enforce

               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

         Committee or the Contract Manager or an individual Pool Member or any
         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.

               that he issues  shall have a Job  Number and a stated  objective.

               objective they will bear a related Job Number.

          5.2  Extensions  to Orders:  Extensions  to Orders may be made only if
               the Order in  respect  of such  extension  bears the same  stated
               objective as the earlier Order.

6.       SUPPLEMENTAL PROVISIONS

6.1      Changing resources: Once the Contract Manager has become aware of the
         identity of a particular person to be allocated to a particular Order

         consultation with and the agreement of the Executive Committee or the

         Manager.

         not delivered in accordance with the terms of that Order, that resource
         shall be delivered at no further cost to Pool Members at such time or
         times as may be reasonably required by the Contract Manager and subject
         to such limits as may be agreed from time to time by the Account

         (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 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 Settlement 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.

                    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.

         Programme there shall be any rebate due to Pool Members in respect of
         the charges of the Settlement System Administrator for the provision of
         Services, Pool Members will be credited a proportionate sum of such

               charges are  exclusive  of United  Kingdom  Value Added Tax which
               shall be added to such charges, if applicable.

3.2      Disputes: If there is any dispute regarding charges in any month, a
         Pool Member may not withhold payment of any invoiced amount but, for
         the avoidance of doubt, may refer such dispute to arbitration in
         accordance with Clause 83 following payment.

3.3      Interest on non-payment: If any amount due to the Settlement System
         Administrator is not received on the due date the Pool Member is
         required to pay such amount, such Pool Member shall pay interest to the
         Settlement System Administrator on such amount from and including the
         date of 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
 the Settlement System Administrator's charges for each SSA Accounting Period
         determined in accordance with Part K.

4.       ALLOCATION OF CHARGES

4.1      Allocation: The Settlement System Administrator shall allocate its
 charges amongst Pool Members in accordance with Part K.

4.2      New and former Pool Members: Any Pool Member which is a Pool Member for
         part only of any month shall pay charges on an interim basis of such
         amount apportioned on a daily basis for each day that it was a Pool
         Member during that month on the basis of the allocation of charges set
         out in Part K. Adjustments to charges on all Pool Members as a result
         of existing Pool Members leaving or new Pool Members joining will be
         set out in the invoice published for the Post Charges for the relevant
         month whereupon the Pool Members and/or former Pool Members shall be
         required to pay such additional amount or shall be entitled to such
         reimbursement.

                                   from that in which data are generally
                                   provided to other Pool Members of the same

                          that they are charged to such Pool Member, have added
                          to them a single lump sum payment for maintenance
                          equal to 40 per cent. of the costs of such charge, as
                          reasonably determined by the Settlement System
                          Administrator);

                  (ii)    shall pay the costs (if any and as far as the same are
                          directly referable to such Pool Member) for the use by

                          or provided by the Settlement System Administrator
                          which are directly referable to such Pool Member; and

                          Generating Units in respect of which standing data
                          have been submitted; and

                          amount as the Executive Committee and the Settlement
                          System Administrator may agree) for each Metering
                          System in respect of which it is the Registrant;

          (c)  thirdly,  but  only  in  respect  of the  first  month in an SSA
               Accounting  Period in which a  Generator  or  Supplier is a Pool
               Member:-

                  (i) subject as provided in paragraphs (ii) to (vii) inclusive

 (2)           A Supplier with a maximum demand at any time       (pound) 2,500
               during such year (as reasonably determined by
               Executive Committee) of less than 200MW or a
               Generator with aggregate Registered Capacity
               of less than 50MW, in either case which
               requires to have delivered to it only its own
               trading information
 (B)           Intermediate
               A Supplier with a maximum demand at

                 Supplier shall pay only one membership fee, being that
                 fee which is the greater of its annual membership fee
                 as a Generator and its annual membership fee as a
                 Supplier (and, if both are the same amount, such Pool
                 Member shall pay only its membership fee as a
                 Generator): such fee shall continue to be payable
                 regardless of any change during the relevant year in
                 the capacity(ies) in which such Pool Member
                 participates as a Pool Member;

         (iii)   unless otherwise resolved by the Executive Committee
                 with respect to the relevant Pool Member, a Pool
                 Member with no demand or generation shall not pay any
                 membership fee and, if the Executive Committee shall
                 so resolve, shall pay only that membership fee
                 referable to a Pool Member falling within the relevant
                 sub-category of paragraph (i)(A) above;

         (iv) if, in its reasonable opinion, the Executive Committee
considers:-

                          (A)      any Pool Member (not being a Pool Member
                                   referred to in paragraph (iii) above) to be
                                   insignificant in terms of generation or
                                   demand, it may waive the membership fee for
                                   such Pool Member until further notice; and

                          (B)      if inequitable or otherwise inappropriate to
                                   levy the full amount of the membership fee
                                   that would otherwise be payable by any Pool
                                   Member, it may waive all or part of such fee
                                   on such terms and for such period(s) as it
                                   reasonably sees fit;

                  (v)              (A) any Pool Member falling within
                                   sub-category (2) of paragraph (i)(A) above
                                   which wishes to receive data by electronic
                                   mail shall be required to pay an additional
                                   monthly membership fee of one-twelfth of
                                   (pound)800; and

                          (B)      any Pool Member which wishes to receive data
                                   by courier shall be required to pay an
                                   additional monthly membership fee of
                                   one-twelfth of (pound)1,000;

                  (vi)    the Executive Committee may from time to time amend
                          the categories of membership and the fees (with the
                          consent of the Settlement System Administrator, such
                          consent not to be unreasonably withheld or delayed);

                  (vii)   the charges referred to in paragraph (b) above and 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;

         (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, 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
                  of the Contributory Shares for such period.

                  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.

2.1      Preparation: No later than 31st January in each year the Pool Funds
         Administrator and the Settlement System Administrator shall agree on a
         Payments Calendar showing for the period from 1st April in that year to

         the Notification Dates on which the Settlement Run in respect of such
         supplies shall be delivered by the Settlement System Administrator to
         the Pool Funds Administrator.

          2.2  Principles:  Each  Payments  Calendar  shall  give  effect to the

                    Settlement System Administrator to the Pool Funds
                    Administrator no later than the 24th day after the
                    Settlement Day to which the Settlement Run relates (or, if
                    such day is not a Business Day, the next succeeding day
                    which is a Business Day);

         2.2.2      the Payment Date shall not fall earlier than two clear
                    Business Days after the day on which the Settlement Run is
                    required to be delivered by the Settlement System
                    Administrator to the Pool Funds Administrator;

          2.2.3expressed  as an average  over the entire  period  covered by the
               Payments  Calendar,  the  Payment  Date  shall  fall,  as near as
               practicable,  28  days  after  the  Settlement  Day to  which  it
               relates; and

         2.2.4 each Payment Date shall fall as close as is reasonably
practicable to the 28th day after the Settlement Day to which it relates,

         and shall be prepared in accordance with the relevant Agreed Procedure.

          2.3  Form:  The  Payments  Calendar  shall  be in  such  form  as  the

         Administrator shall fail to agree a Payments Calendar for any period by
         the date stated in sub-section 2.1 or the Payments Calendar prepared by
         them does not give effect to the principles set out in sub-section 2.2,
         the Executive Committee shall prepare or cause to be prepared a
         Payments Calendar for that period giving effect to the said principles
         and that shall be the Payments Calendar for use for that period.

         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

                    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 Shortfall or the amount held in the Pool Reserve
                    Account attributable to such Pool Debtor (whichever is less)
                    on the trusts set out in sub-section 5.1 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 and the amount overdue
         shall be the amount of the Shortfall.

5.7      Shortfall: The term "Shortfall", as used in this Section 5, 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 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 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: 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. 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.
5.9      Funds not to be withdrawn: Each Providing Member and the Grid Operator
         undertakes not to seek withdrawal of any funds to which it may be
         entitled except in the circumstances permitted by sub-section 5.10 or
         16.7. The Pool Funds Administrator shall be entitled to disregard any
         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
                    the Grid Operator is required to maintain in the Pool
                    Reserve Account from time to time in accordance with Section
                    16.

5.11     Waiver of Providing Members' and Grid Operator's rights: Each Providing
         Member and the Grid Operator waives any right it might otherwise have
         to set off against any obligation owed to the Pool Funds Administrator,
         the Pool Banker, any Pool Member, the Ancillary Services Provider or
         the Grid Operator any claims such Providing Member or the Grid Operator
         may have to or in respect of the Pool Reserve Assets.

5.12     Pool Reserve Assets: "Pool Reserve Assets" means the aggregate of:-

          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 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
                    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, 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 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:  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  the
               Agreement  or  the   provision  of  Ancillary   Services  do  not
               correspond  exactly with their  respective  payment  entitlements
               established  in  accordance  with the  Agreement  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,  on the written  instruction  of the Pool
               Funds Administrator, shall account in accordance with sub-section
               23.2   to  the   Pool   Funds   Administrator   accordingly   for
               redistribution of the moneys.

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
               sub-section  5.1 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 paragraphs 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 the 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 to
         receive payments in respect of that same day.

6.       POOL LEDGER ACCOUNTS

6.1      Maintenance of Pool Ledger Accounts: The Pool Funds Administrator shall
         maintain ledger accounts showing all amounts payable and receivable by
         each Pool Member, the Ancillary Services Provider and the Grid Operator
         according to calculations made and notifications issued by the Pool
         Funds Administrator pursuant to this Schedule.

6.2      Ledger extracts: Each Pool Member, the Ancillary Services Provider and
         the Grid Operator shall be entitled to receive a quarterly extract of
         the ledger account which is relevant to it showing all amounts debited
         and credited to its account provided that, if a Pool Member, the
         Ancillary Services Provider or the Grid Operator so requests of the
         Pool Funds Administrator, it shall be entitled to receive a monthly
         extract of such ledger account.

6.3      Certified copy extracts: Without prejudice to the generality of the
         general duties and responsibilities of the Pool Funds Administrator set
         out in Schedule 15, in the event of any enforcement proceedings being
         brought by a Pool Creditor against a non-paying Pool Member or the Grid
         Operator, the Pool Funds Administrator shall forthwith upon request
         being made to it at the cost of the requesting Pool Creditor provide a
         certified copy of an extract of the ledger accounts sufficient to
         establish the details of each transaction in respect of which the Pool
         Creditor has a claim against the non-paying Pool Member or the Grid
         Operator.

6.4      Confidentiality: The ledger accounts maintained by the Pool Funds
         Administrator shall be kept confidential in accordance with Part XVIII
         of the Agreement from Committee Members and from all Pool Members and
         the Grid Operator (except as required pursuant to Clause 63.1.5 or
         63.1.6 or sub-section 6.2 or 6.3) but the Pool Funds Administrator
         shall disclose such ledger accounts to the Pool Auditor for the purpose
         of any audit requested to be conducted pursuant to Part IX of the
         Agreement.

6.5      Information: Any extract of a ledger account of any other records, data
         or information provided pursuant to Clause 63.1.5 or 63.1.6 or
         sub-section 6.2 (collectively referred to in this Section 6 as the
         "information") shall, save in the case of manifest error, be deemed
         prima facie evidence of its contents.

6.6      Review of extracts: Each Pool Member, the Ancillary Services Provider
         and the Grid Operator shall promptly review all extracts of ledger
         accounts sent to it and shall (without prejudice to any of its rights
         under the Agreement) where practicable within 10 Business Days after
         receiving such information notify the Pool Funds Administrator of any
         errors in such account of which it is aware.

6.7      Dispute of accuracy: If the Pool Funds Administrator at any time
         receives a notice disputing the accuracy of any ledger account,
         records, data or information, it shall consult with the Pool Member who
         gave the notice, the Ancillary Services Provider or (as the case may
         be) the Grid Operator and each shall use all reasonable endeavours to
         agree the information. Promptly after agreement is reached, the Pool
         Funds Administrator shall, if necessary, issue corrected information
         and notifications under the provisions of sub-section 17.8.

                          Funds Administrator:-

          (i)  a Letter of Credit  (available  for an initial period of not less

                          in paragraph 15.1.2(a) above) shall, not later than
                          the date of its admission as a Pool Member or 31st
                          March, 1995 (whichever is the later) and the Grid
                          Operator shall, not later than 1st April, 1997,
                          deliver to the Pool Funds Administrator:-

               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

         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 the terms set

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 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;

                    the required Security Amount applicable to it (less its
                    balance on the Pool Reserve Account) which Letter of Credit

                    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 sub-section 1.1 under "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
         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 the 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 the 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 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

         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: Upon a Providing Member
         ceasing to be a Pool Member or the Grid Operator ceasing to be a Party
         to the Agreement (as the case may be) and provided that all amounts
         owed by the Providing Member or the Grid Operator have been duly and
         finally paid and that it is not otherwise in default in any respect
         under the Agreement, the Providing Member or the Grid Operator shall be
         released from the obligation to maintain Security Cover and the Pool
         Funds Administrator shall consent to the revocation of any outstanding
         Letter of Credit.

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.

                    Added Tax thereon) shall be:-

                    (a) if verification has been made in accordance with
sub-section 17.6, the full relevant amounts so verified;

                    (b)   to the extent verification can reasonably be made in
                          circumstances where all the information cannot be
                          fully verified as described in sub-section 17.6, those
                          amounts which are shown against the name of each Pool
                          Debtor in such information as is received under the
                          provisions of sub-section 17.1 (whether or not such
                          information is an estimate only) and such amounts will
                          be shared amongst the relevant Pool Creditors in the

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

                    (c)   to the extent that for any reason whatever the amounts
                          to be paid cannot be verified at all (including, but
                          not limited to, application of Force Majeure and
                          failure to provide information on the part of the
                          Settlement System Administrator) or the appropriate
                          calculations to permit payment in accordance with
                          sub-paragraph (b) above cannot properly be made, the
                          same as the amounts calculated as being payable by and
                          to Pool Members, to the Ancillary Services Provider
                          and by the Grid Operator in respect of the last same
                          day of the week in respect of which payments were
                          verified under sub-section 17.6 (provided that any
                          Pool Member who was not at that earlier time a Pool
                          Member, or vice versa, shall be ignored and such
                          adjustment made as the Pool Funds Administrator
                          considers appropriate).

         17.9.2     In the event that payments are made in the circumstances set
                    out in paragraph 17.9.1(b) or (c), the Settlement System
                    Administrator in conjunction with the Pool Funds
                    Administrator shall, as soon as actual verification can
                    thereafter be made, make such adjustments as may be
                    necessary (and, where relevant, apply interest at the
                    Reserve Interest Rate or at such rate as shall be set from
                    time to time by the Executive Committee) to account for any
                    differences between payments made and actual verified
                    payment information.

17.10    Postponed Payment Date: If for any reason beyond the reasonable control
         of the Pool Funds Administrator it is not possible, after application
         of sub-section 17.9, 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 Payment Date
         shall be postponed so that it falls on the second Business Day after
         the day on which the Pool Funds Administrator verifies the information
         provided by the Settlement System Administrator pursuant to sub-section
         17.6 (any such Payment Date being the "Postponed Payment Date" and a
         reference to a Payment Date in this Schedule shall where applicable
         include a reference to a Postponed Payment Date). On the Postponed
         Payment Date, each Pool Member who took electricity on the Settlement
         Day to which the Postponed Payment Date applies and the Grid Operator
         shall pay interest on all such amounts for each day from and including
         the originally scheduled Payment Date to (but excluding) the Postponed
         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 Reserve
         Interest 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.

17.11    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 Clause 52, the Pool Funds 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 Debtor: Without prejudice to its obligations in respect
         of supplies of electricity in accordance with the provisions of the
         Agreement, 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. 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. 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.

         thereto and the amount (if any) of tax to be withheld.

19.      PAYMENT PROCEDURE

19.1     Instructions for payment: 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. 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.

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
                    verifies 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: 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 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. 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: 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. As soon as practicable and
         not later than 14.30 hours on that day the Pool Funds Administrator
         shall give irrevocable instructions to the Pool Banker to remit from
         the Pool Clearing Account to the relevant Settlement Accounts
         maintained by the Pool Creditors the aggregate of amounts determined by
         the Pool Funds Administrator to be available for payment to Pool
         Creditors and, if required, to transfer 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
         in respect of the longest outstanding Settlement Day shall be, and be
         deemed to be, settled first.

19.9     Bank contacts: 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. 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. 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 the Agreement not substituted by the provisions of this Section 20,
         the provisions set out in this Section 20 shall apply:-

         20.1.1     if, on the Effective Date, it has not been possible to
                    establish the Notified Payments System (in which case they
                    shall continue to apply until the Notified Payments System
                    is established, or until such other time as the Executive
                    Committee may determine); or

         20.1.2     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.

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 the 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 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 as provided by 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
               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
               Reserve  Interest  Rate 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 Reserve  Interest Rate 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; 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 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 Reserve Interest Rate.

          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 Reserve Interest Rate.

          21.7 Indemnification  by non-paying  Pool Debtor:  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.  The Pool Creditors, in proportion
               to the  amounts  payable to them on the  Payment Date to which a
               default relates in respect of which the Pool Funds Administrator
               has operated  sub-section 21.5, and any succeeding Payment Dates
               as may be required,  shall  indemnify and keep indemnified  each
               Pool Member as is referred to in the earlier  provisions of this
               sub-section  21.7  and the Grid  Operator  to the  extent of any
               failure by the non-paying  Pool Debtor to fulfil its  obligations
               under this sub-section 21.7.

21.8     Notification to Pool Creditors: The Pool Funds Administrator shall use
         all reasonable endeavours promptly to notify the relevant Pool
         Creditors whenever it makes any such reduction as is referred to in
         paragraph 21.1.6.

21.9     Default Interest: Save as otherwise provided in the Agreement
         (including where an express rate of interest is provided), if any
         amount payable by any Pool Debtor pursuant to this Schedule is not
         given value for the due date by close of banking business on the due
         date the Pool Debtor shall on written demand by the Pool Funds
         Administrator pay to the Pool Funds Administrator, for the account of
         the person or persons entitled to receive the amount in default,
         interest on such amount from the due date up to the day of actual
         receipt by the Pool Funds Administrator (after as well as before
         judgment) at the Default Interest Rate.

21.10    Application of payments: Any amount received by the Pool Funds
         Administrator from a non-paying Pool Debtor for the credit of any Pool
         Account shall be applied by the Pool Funds Administrator in or towards
         payment of amounts payable by the non-paying Pool Debtor to Pool
         Creditors on each successive Payment Date in respect of which there is
         an outstanding default (with the longest outstanding default being
         settled first).

21.11    Clearing of Pool Clearing Account: All amounts standing to the credit
         of the Pool Clearing Account at the close of business on any Payment
         Date shall be transferred to the Pool Reserve Account so that the
         balance in the Pool Clearing Account shall at the end of such day be
         nil.

21.12    Credit Facility: If and for so long as the Credit Facility remains
         unconditionally available, the provisions of this Section 21 shall
         apply  with the modifications provided by Section 25.

23.1     Overpayments: If for any reason whatsoever (including the negligence of

         receives on any Payment Date a payment in excess of the amount
         disclosed in the Pool Ledger Account as calculated as being payable to
         it (an "overpayment") (including but not limited to the proceeds of any
         loan made or deemed to be made in accordance with Section 21 or Section
         25 to any non-paying Pool Debtor which becomes insolvent before such
         advance is repaid) the provisions of sub-section 5.15 apply, and the
         Pool Creditor shall forthwith notify the Pool Funds Administrator of
         the amount of the overpayment and shall forthwith pay the overpayment
         into a Pool Account specified by the Pool Funds Administrator.

23.2     Repayment of overpayment (1): If prior to a Pool Creditor notifying the
         Pool Funds Administrator of the overpayment, the Pool Funds
         Administrator receives notice (from the Pool Banker or otherwise) of
         the overpayment, the Pool Funds Administrator shall forthwith require
         (by written notice) that the recipient of the overpayment pay the
         overpayment to a Pool Account specified by the Pool Funds Administrator
         and any Pool Creditor who receives such notice shall forthwith pay the
         amount to an account specified by the Pool Funds Administrator. If the
         overpayment is repaid within two Business Days of receiving the notice,
         the overpayment (or any part not paid) shall bear interest at the
         Reserve Interest Rate or at such rate as shall be set from time to time
         by the Executive Committee from the date the overpayment was received
         up to the date that value is given in a Pool Account by the Pool Funds
         Administrator (after as well as before judgment). Any overpayment (or
         part thereof) not repaid within two Business Days after demand therefor
         in accordance with this Section 23 shall bear interest at the Default
         Interest Rate from the expiry of that period and shall be recoverable
         in accordance with Section 24. The Pool Funds Administrator shall
         account to those entitled to payment by reason of an overpayment.

23.3     Repayment of overpayment (2): Upon receipt of the overpayment
         (including any interest) the Pool Funds Administrator shall (forthwith
         upon entitlement to it being ascertained) pay the amount received to
         the Pool Member, the Ancillary Services Provider or the Grid Operator
         who should have received the payment on the Payment Date.

23.4     Underpayments: If for any reason whatsoever (including the negligence
         of the Pool Banker or the Pool Funds Administrator) a Pool Creditor
         does not receive on the relevant Payment Date the 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. If,
         by reason of negligence, the Pool Funds Administrator holds or has
         under its control amounts which it ought properly to have paid to Pool
         Members, the Ancillary 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.

24.      ENFORCEMENT OF CLAIMS

24.1     Notification of amount in default: Without prejudice to the provisions
         of Section 21, if a Pool Member or the Grid Operator shall fail to pay
         any amount payable pursuant to this Schedule on the due date, the Pool
         Funds Administrator shall notify the Director, the Executive Committee
         and each Pool Creditor to whom the amount in default is owed pursuant
         to this Agreement of the name of the non-paying Pool Debtor, the
         aggregate amount in default and the amount owed to each Pool Creditor.

24.2     Duties of Pool Funds Administrator: Except as otherwise expressly
         provided in this Schedule, the Pool Funds Administrator shall not be
         required to ascertain or enquire as to the performance or observance by
         any Pool Member, the Ancillary Services Provider or the Grid Operator
         of its obligations under the Agreement and shall have no duty to inform
         the Executive Committee or any Pool Member, the Ancillary Services
         Provider or the Grid Operator of any default, other than a failure to
         pay as may come to its attention.

24.3     Notice before action: Each Pool Creditor shall give notice to the Pool
         Funds Administrator before instituting any action or proceedings in any
         court to enforce payments due to it pursuant to this Schedule. Upon
         receipt of any notice under this sub-section 24.3, the Pool Funds
         Administrator will as soon as practicable notify the Executive
         Committee, all Pool Members, the Settlement System Administrator, the
         Ancillary Services Provider, the Grid Operator and the Director.

24.4     Proceedings to Recover Overdue Amounts: Without prejudice to the right
         of any Pool Member or the Grid Operator to bring such proceedings as it
         sees fit in connection with matters related to the Agreement, the Pool
         Funds Administrator shall, if instructed to do so by the Executive
         Committee, bring proceedings against a Pool Member or the Grid Operator
         (on behalf of those Pool Members and/or (as the case may be) the Grid
         Operator who have (has) indicated their (its) willingness to the
         Executive Committee for the Pool Funds Administrator first so to act)
         for the recovery of any amounts due by that Pool Member or (as the case
         may be) the Grid Operator pursuant to this Schedule so long as the Pool
         Funds Administrator has first reached agreement with the Executive
         Committee, those Pool Members and/or (as the case may be) the Grid
         Operator as to appropriate remuneration, is indemnified to its
         reasonable satisfaction or, if it so requires, provided that it shall
         have received such security as it may reasonably request against all
         costs, claims, expenses (including legal fees) and liabilities which it
         will or may sustain or incur in complying with such instructions. Save
         as provided in the foregoing provisions of this sub-section 24.4, the
         Pool Funds Administrator shall not be obliged to 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 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),
         paragraphs 15.1.2, 21.1.3 and 21.1.5 shall be of no effect and the
         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;

         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

         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 paragraph
         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, 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 Clause 21.

26.      CREDIT FACILITY: GENERAL

                    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.

                          without the approval of the Executive Committee; or

                    (b) cancel the Credit Facility unless either the approval of

          26.3.2 The Pool Funds Administrat or shall cancel the Credit Facility

               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

         relevant Credit Facility Contribution).

         thereafter during which the Credit Facility is in place, pay each year

                                   SCHEDULE 13

                               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 Quarter:-

         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 Votes Calculation Period
                  relative to such Quarter, as determined from the final run of
                  Settlement for each such Settlement Period; 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 Consumer Metered Demand taken by that Pool
                  Member in all Settlement Periods falling in the Votes
                  Calculation Period relative to such Quarter, as determined
                  from the final run of Settlement for each such Settlement
                  Period.

                  For the purposes of this paragraph 2:-

                  (A)      a Generating Unit shall be an Allocated Generating
                           Unit of a Pool Member (in this paragraph, 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 Quarter pursuant to
                           paragraph 6. If at any time during such Quarter an
                           Allocated Generating Unit shall belong to another
                           Pool Member (in this paragraph, the "Transferee Pool
                           Member"), the Contributory Shares
                                           ----------------------
                           attributed to the Identified Pool Member for such
                           Quarter 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; and

                    (E)  the Executive  Committee  may, upon application of any
                         Pool Member involved in any transfer of assets between
                         Pool Members during any Quarter, adjust as between the
                         Pool Members involved in such transfer,  the number of
                         Points  and/or  Weighted  Votes to which they in their
                         capacities as Suppliers are entitled in respect of the
                         remaining part of that  Quarter  and/or one or both of
                         the two immediately  succeeding  Quarters  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.

3.       New Pool Members: Until the third Quarter Day next falling after the
         date of its admission as a Pool Member, any Party which is admitted as
         a Pool Member pursuant to Clause 8.2 shall receive that number of
         Points as is equal to one thousand times the number of Weighted Votes
         to which such Pool Member would have been entitled under Clause
         11.3.1(b) had:-

         3.1       the provisions of Clause 11.3.3 been ignored; and

         3.2      any applicable restrictions under Clause 11.4 been ignored,

         as determined by the Executive Committee. Thereafter, such Pool
         Member's Points shall be calculated in accordance with paragraph 2.

4.   Calculation  of Points:  On or prior to each Quarter Day and at such other
     times as are referred to in paragraph 6 the Executive  Committee shall, on
     the  basis  of  information  to  be  supplied  by  the  Settlement  System
     Administrator as referred to in Clause 11.3.2, calculate for the Following
     Quarter or (as the case may be) the  remainder of the then current Quarter
     the  number of  Points  which  each  Pool  Member  whose  Points are to be
     calculated in accordance  with paragraph 2 shall receive, and shall notify
     each Pool  Member  and the  Director  in  writing  of the number of Points
     received  by all  Pool  Members  (whether  calculated  in accordance  with
     paragraph 2 or 3). The  determination of the Executive Committee as to the
     number of Points of each Pool  Member  shall (in the absence  of  manifest
     error) be final and binding for all purposes of this Agreement.

5.   Contributory  Shares:  The  Contributory  Share of a Pool  Member  shall be
     calculated in accordance with the following formula:-

         CS = X + Y

         Where:-

         X =   A
                2 x B

         Y =   C
                2 x D

         and where:-

          CS   = the  Contributory  Share of such Pool  Member,  expressed  as a
               percentage

          A    = the number of Points for the time being of such Pool  Member in
               its capacity as a Generator

         B                = the number of Points for the time being of all Pool
                          Members which are Generators, in their capacity as
                          such

         C                = the number of Points for the time being of such Pool
                          Member in its capacity as a Supplier

         D                = the number of Points for the time being of all Pool
                          Members which are Suppliers, in their capacity as
                          such.

6.       Calculation of Contributory Shares: On or prior to:-

         6.1       each Quarter Day;

         6.2  each  date  upon  which a New Party is  admitted,  resigns  or is
               removed as a Pool Member; and

         6.3  each date upon which there is a change in the capacity in which a
               Pool Member participates as a Pool Member,

                  the Executive Committee shall calculate for the Following
                  Quarter or (as the case may be) the remainder of the then
                  current Quarter the Contributory Share for the time being of
                  each Pool Member, and shall notify each Pool Member and the
                  Director in writing of the Contributory Share of each of the
                  Pool Members. The determination of the Executive Committee as
                  to the Contributory Share of each Pool Member 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.

8.       Additional Capacity: For the purposes of Section 3, 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 and, until the third
         Quarter Day next falling after the date such Pool Member's application
         to the Executive Committee pursuant to Clause 8.12 is approved, it
         shall receive that number of Points as is equal to one thousand times
         the number of Weighted Votes to which such Pool Member would have been
         entitled under Clause 11.3.1(b) had:-

         8.1       the provisions of Clause 11.3.3 been ignored; and

         8.2       any applicable restrictions under Clause 11.4 been ignored,

         as determined by the Executive Committee. Thereafter, such Pool
         Member's Points shall be calculated in accordance with paragraph 2.

         each Pool Member and the Ancillary Services Provider and agreed to act
         as the Pool Funds Administrator. This Schedule sets out the terms and
         conditions on and subject to which EPFAL shall continue and agrees to
         continue to act as the Pool Funds Administrator for the period referred
         to in sub-section 2.2 (as such period may be extended or further
         extended in accordance with the terms of this Schedule).

2.2      Term: EPFAL's appointment as the Pool Funds Administrator on and
         subject to the terms and conditions set out in this Schedule shall be
         deemed to have commenced on the PFA Commencement Date and, subject as
         hereinafter provided in this Schedule, shall end on 31st March, 1995
         (the period from the PFA Commencement Date to 31st March, 1995 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

         and otherwise in acting as the Pool Funds Administrator under the
         Agreement, EPFAL shall act as an independent contractor and (unless

         out nor be held out as acting as agent for any of the other Parties.

     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

          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

8.1      General: In consideration of the carrying out by EPFAL of its duties
         and responsibilities as the Pool Funds Administrator as set out in the
         Agreement and the Agreed Procedures (other than in respect of those
         matters for which EPFAL is or will be compensated through the recovery
         of the PFA Operating Costs in accordance with this Schedule) EPFAL
         shall be paid an annual fee as the Pool Funds Administrator (the
         "Annual Fee") calculated in accordance with the following provisions of
         this Section 8.

8.2      Calculation of fee:

         8.2.1      In respect of the PFA Accounting Period beginning on the PFA
                    Commencement Date the Annual Fee for that PFA Accounting
                    Period shall be (pound)1,250,000 (the "Base Sum").

         8.2.2      In respect of each PFA Accounting Period beginning on an
                    anniversary of the PFA Commencement Date the Annual Fee
                    (expressed in pounds sterling) for that PFA Accounting
                    Period shall be calculated in accordance with the following
                    formulae:-

                    (a)   ABS = Base Sum * (1+(RPIp/100))

                          where             RPIp = the percentage change
                                            (whether of a positive or negative
                                            value) in the Retail Price Index
                                            between that published in, or (as
                                            the case may be) the substitute
                                            index for, the third month before
                                            the PFA Commencement Date and that
                                            published in, or the substitute
                                            index for, the third month before
                                            the anniversary from which the
                                            adjusted Annual Fee is to take
                                            effect;

                    (b)   ATPM = Base Sum * (I/100)

                          where             I = the value set out in column 2
                                            below opposite the number of Active

                                            adjusted Annual Fee is to take
                                            effect:-

                                    121 to 130                      45
                                    131 to 140                      50
                                    141 to 150                      55


                    (c) Annual Fee = ABS + ATPM.

          8.2.3If during any PFA Accounting Period beginning on an anniversary
               of the PFA  Commencement Date the number of Active  Trading Pool
               Member Identities shall change such that, were the Annual Fee for
               that PFA Accounting  Period to be recalculated,  it would yield a
               different  result from that originally  calculated  for that PFA
               Accounting  Period  (or, as the  case  may be,  from  that  most
               recently  recalculated for that PFA Accounting Period pursuant to
               this paragraph 8.2.3) EPFAL shall promptly recalculate the Annual
               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 paragraph 8.3.2(b), such recalculated Annual Fee shall
               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 paragraph 8.2.3).

8.3      Review of fee:

         8.3.1      If at any time the total number of Active Trading Pool
                    Member Identities shall exceed 150 EPFAL may request the
                    Executive Committee to review the basis of calculation
                    and/or the amount of the Annual Fee. Upon receipt of such
                    request the Executive Committee and EPFAL shall negotiate in
                    good faith for a period not exceeding three months (or such
                    longer period as EPFAL and the Executive Committee may agree
                    in writing) with a view to agreeing a revised basis of
                    calculation and/or amount of the Annual Fee.

         8.3.2            (a) If EPFAL and the Executive Committee shall agree a
                          revised basis of calculation and/or amount of the
                          Annual Fee, such revisions shall take effect in
                          accordance with the terms of that agreement.

          (b)  If at the end of the negotiation  period referred to in paragraph
               8.3.1 EPFAL and the Executive  Committee  shall not have agreed a
               revised basis of  calculation  and/or amount of the Annual Fee or
               if the Executive  Committee  shall dispute any calculation of the
               Annual Fee made by EPFAL and notified to the Executive  Committee
               pursuant to  sub-section  9.4 or  paragraph  8.2.3,  EPFAL or the
               Executive Committee may refer the dispute to arbitration pursuant
               to Clause 83. Pending the award of the  arbitrator(s)  the Annual
               Fee   current   as  at  the  date  of  EPFAL's   calculation   or
               recalculation shall continue in force.

9.       PFA BUDGETS AND NOTICES OF ANNUAL FEE

9.1      PFA Budgets: Not earlier than three nor later than two months prior to
         the first day of each PFA Accounting Period EPFAL shall prepare and
         submit to the Executive Committee a PFA Budget for such PFA Accounting

         expenditure in respect of such item or category for the remainder of
         the then current PFA Accounting Period and report any salient
         differences between any such forecast expenditure and the budgeted
         expenditure in respect of each such item or category in the immediately
         preceding PFA Budget.

9.3      Form of PFA Budgets: Each PFA Budget shall be substantially in the form
         of that set out in Annex 1 (or in such other form as EPFAL and the
         Executive Committee may from time to time agree in writing).

9.4      Notice of Annual Fee: Each PFA Budget (other than the PFA Budget for
         the PFA Accounting Period beginning in 1992) shall be accompanied by a
         Notice of Annual Fee prepared by EPFAL stating the Annual Fee for the
         PFA Accounting Period to which such PFA Budget relates and setting out
         in reasonable detail the calculation of the Annual Fee. Subject to

               the date in any PFA Accounting Period of the  publication of the
               audited accounts for the Funds Transfer Business for the previous
               PFA  Accounting  Period,  EPFAL shall  prepare and submit to the
               Executive Committee and all Pool Members a Statement of Costs and
               Fees  for  such  previous  PFA Accounting  Period.  The  audited
               accounts  of EPFAL,  the  instruction letter  from  EPFAL to its
               auditors giving  instructions for the auditing of those accounts
               and  the  auditors'  management letter  (to the  extent  that it
               relates to the economy, efficiency, effectiveness and quality of
               service of EPFAL in carrying out its duties and  responsibilities
               as the Pool Funds  Administrator) shall accompany each Statement
               of Costs and Fees for each entire PFA Accounting Period.

          10.2 Form of Statement of Costs and Fees:  The Statement of Costs and
               Fees for any PFA Accounting Period:-

         10.2.1     in relation to the PFA Operating Costs, shall attribute
                    actual and accrued expenditure for such period against,
                    inter alia, each of the categories and sub-categories set
                    out in the corresponding PFA Budget for such PFA Accounting
                    Period; and

         10.2.2     in relation to the Annual Fee, shall state the Annual Fee
                    and any revisions thereto for such PFA Accounting Period and
                    shall set out in reasonable detail the calculation thereof.

10.3     Accompanying Report: Each PFA Budget and Statement of Costs and Fees
         for an entire PFA Accounting Period submitted to the Executive
         Committee and, in the case of the Statement of Costs and Fees, Pool
         Members pursuant to sub-section 9.1 or 10.1 shall be supported by a
         written report of EPFAL commenting in reasonable detail upon the
         matters comprised in the categories of expenditure included in such PFA
         Budget or Statement of Costs and Fees.

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 sub-section 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
                    sub-section 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.

10.5     Basis of preparation: All Statements of Costs and Fees other than a
         Statement of Costs and Fees in respect of an entire PFA Accounting
         Period shall be unaudited but prepared on a best estimates basis. The
         Statement of Costs and Fees in respect of an entire PFA Accounting
         Period shall be audited by EPFAL's auditors.

          10.6 Accounting Practices: Each PFA Budget and Statement of Costs and
               Fees shall be prepared on the basis of the accounting  principles
               and practices used to draw up the most recent audited accounts of
               EPFAL and  consistently  applied.  If any  Statement of Costs and
               Fees for an entire PFA Accounting  Period is not prepared on such
               basis, EPFAL shall prepare and submit to the Executive  Committee
               and all Pool Members a pro-forma set of its audited  accounts for
               such entire PFA Accounting  Period which is prepared on the basis
               of the  accounting  principles  and practices used to prepare the
               relevant  Statement  of  Costs  and  Fees.  Any  changes  in  the
               accounting   principles   and   practices   or  their  method  of
               application  used to prepare  EPFAL's  audited  accounts shall be
               noted in the next  following PFA Budget or Statement of Costs and
               Fees, as the case may be.

10.7 Statement of Charges: A Statement of Charges shall accompany each Statement
of Costs and Fees.

11.      QUALITY OF SERVICE REVIEW

11.1     Complaints: If the Executive Committee shall receive from any Pool
         Member written notification of a breach or an alleged breach of the
         Agreement or an Agreed Procedure involving EPFAL in its capacity as the
         Pool Funds Administrator it shall promptly notify EPFAL of receipt and
         shall send a copy of such notification to EPFAL.

11.2     Report: Within one month after receipt from the Executive Committee of
         any such notification as is referred to in sub-section 11.1 EPFAL shall
         prepare and submit to the Executive Committee a written report
         explaining in reasonable detail the circumstances which gave rise to,
         and the causes of, the breach (or, if it asserts that there has not
         been a breach, the reasons in support of that assertion), any remedial
         action taken by it and the consequences of such action.

          11.3 Quality  of Service Review:  Promptly  after  receipt of EPFAL's
               written  report referred  to in  sub-section  11.2 (or, if EPFAL
               shall fail to submit a report within the period  referred  to in
               that  sub-section,  promptly after  expiry of that  period)  the
               Executive   Committee  shall determine   whether  it  wishes  to
               commission   a  Quality  of Service   Review.   In  making  such
               determination the Executive Committee shall take into account the
               nature and seriousness of the notified breach (or alleged breach)
               and the said written  report (if any).  The  Executive  Committee
               shall notify EPFAL in writing of any such determination.

11.4     Consultants: If the Executive Committee shall determine to commission a
         Quality of Service Review, it shall instruct the Consultants to conduct
         such review and to report in writing (a "Review Report") to the
         Executive Committee and EPFAL.

11.5     Terms of engagement: The terms of engagement of the Consultants
         (including the objectives and scope of the work to be performed and the
         form of report to be issued) in respect of any Quality of Service
         Review shall (subject to sub-section 11.10) be determined by the
         Executive Committee in consultation with EPFAL.

          11.6 Review  Report:  EPFAL shall be given the opportunity to examine
               and comment on any factual details contained in any Review Report
               before it is submitted in final form.  Such final form shall, if
               the Consultants commissioned to carry out the Quality of Service
               Review shall think fit, take into  consideration the comments of
               EPFAL on any factual  details contained in the Review Report and
               include an  indication  of the response  and proposed  action of
               EPFAL.  A copy of the final  form of the Review Report  shall be
               sent to EPFAL and may be distributed  by the Executive Committee
               to Pool Members and the Director.

11.7     Implementation: Upon receipt of a Review Report, EPFAL shall (if so
         required by and in consultation with the Executive Committee) give
         effect to such recommendations, if any, as are set out in such report
         as soon as is reasonably practicable following the date of receipt by
         EPFAL of such report.

11.8     Arbitration: If EPFAL shall in good faith consider the recommendations
         in any Review Report to be impractical or inappropriate, the same shall
         be referred for resolution to arbitration in accordance with Clause 83.

          11.9 Access: For the purposes of any Review Report, EPFAL shall permit
               the Consultants access to the Funds Transfer Hardware,  the Funds
               Transfer  Software and all data used by EPFAL in the operation of
               the  Funds  Transfer  System  and to such of its  company  books,
               accounts and vouchers as relate to any of the items or categories
               of expenditure  which make up the PFA Operating  Costs and as are
               necessary for the  performance of the Quality of Service  Review.
               The  Consultants  shall also be entitled to require  from EPFAL's
               officers,  employees or agents such  information and explanations
               as are  necessary for the  performance  of the Quality of Service
               Review (but, for the avoidance of doubt,  the  Consultants  shall
               not have  access to any data  used,  information  held or records
               kept in relation to any Pool Member  without  such Pool  Member's
               prior written consent).

11.10    Confidentiality: The terms of engagement of the Consultants
         commissioned to carry out the Quality of Service Review shall include a
         written obligation of the Consultants and signed on their behalf in
         favour of EPFAL to keep confidential information made available by
         EPFAL to the Consultants or to which the Consultants have access for
         the purposes of the Quality of Service Review save that the Consultants
         shall be entitled to disclose any such information:-

         11.10.1    in the Review Report to the extent that the Consultants
                    reasonably consider appropriate (after consultation with
                    EPFAL) for the purposes of that report; or

         11.10.2   with the prior written consent of EPFAL; or

         11.10.3    in compliance with any requirement of law or pursuant to the
                    arbitration rules of the Electricity Arbitration Association
                    or pursuant to any judicial or other arbitral process or
                    tribunal having jurisdiction.

11.11    Additional rights: The provisions of this Section 11 are in addition to
         (and not in substitution for) and shall not prejudice any other rights
         which the Executive Committee or any Pool Member may have in respect of
         any such breach as is referred to in sub-section 11.1.

12.      AUDITORS' OPINION

         The Statement of Costs and Fees in respect of an entire PFA Accounting
         Period to be sent to the Executive Committee and all Pool Members
         pursuant to sub-section 10.1 shall be accompanied by a report from
         EPFAL's auditors considering whether in such auditors' opinion:-

          (a)  the  Statement of Costs and Fees is in  agreement  with  EPFAL's
               underlying books and records;

         (b)        PFA Operating Costs have been properly extracted from
                    EPFAL's audited financial statements; and

         (c)        the calculations in respect of the Annual Fee are in
                    accordance with the formulae set out in sub-section 8.2, and
                    are correct and in agreement with EPFAL's underlying books
                    and records.

13.      PFA ACCOUNTING PERIOD

         Each PFA Accounting Period shall be for a period of 12 months unless
         otherwise agreed in writing by EPFAL and the Executive Committee. If
         EPFAL wishes to change its accounting reference date it shall give due
         notice thereof to the Executive Committee which shall agree to enter
         into an amending agreement to the Agreement in order to give effect to
         the same at EPFAL's cost and expense.

14.      THE POOL FUNDS ADMINISTRATOR'S CHARGES

         EPFAL shall be entitled to recover from all Pool Members the charges
         set out in Sections 15 and 16 in respect of its operation of the Funds
         Transfer Business but, subject to Section 19, shall not be entitled to
         recover any other charges.

15.      AMOUNT

          15.1 Annual Charges: In respect of each PFA Accounting Period,  EPFAL
               shall be entitled to recover from Pool  Members  annual  charges
               equal to the aggregate of the following amounts:-

         15.1.1     PFA Operating Costs for the relevant PFA Accounting Period
                    (as identified by the Statement of Costs and Fees for such
                    period submitted pursuant to Section 10);

         15.1.2 the PFA Handling Charge, calculated on the total amount of the
PFA Operating Costs;

         15.1.3    the Annual Fee for such PFA Accounting Period; and

         15.1.4    the Bank Charges.

15.2     Recovery of Charges:

         15.2.1     The due proportion (determined in accordance with
                    sub-section 15.4) of EPFAL's annual charges referred to in
                    sub-section 15.1 payable by each Pool Member for each PFA
                    Accounting Period shall be recovered by monthly payments in
                    advance from each Pool Member or, where EPFAL and the Pool
                    Member otherwise agree, semi-annually in advance (calculated
                    on a best estimates and reasonable basis to be one twelfth
                    or, as the case may be, one half of the annual charges
                    payable by such Pool Member by reference to the most recent
                    PFA Budget).

         15.2.2     EPFAL shall advise each Pool Member of such amount by
                    invoice despatched to each Pool Member approximately 15 days
                    prior to the first day of each month or, as the case may be,
                    other period. Such invoice shall be paid no later than the
                    first day of such month or such other period. Each Pool
                    Member shall pay the amount advised in the relevant invoice
                    within 15 days after the invoice date.

         15.2.3     Each Pool Member shall pay all amounts due hereunder 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 are exclusive of United Kingdom Value Added Tax
                    which shall be added to such charges, if applicable.

         15.2.4     In the event of any dispute regarding charges 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.

15.3     Interest on non-payment: If any amount due to EPFAL in its capacity as
         the Pool Funds Administrator is not received on the due date the Pool
         Member required to pay such amount shall pay interest to EPFAL on such
         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.

15.4     Payment of Charges: Each Pool Member shall pay its due proportion of
         EPFAL's charges for each PFA Accounting Period determined in accordance
         with Section 17.

          15.5 Amount of  Charges:  The amount of each  such  payment  shall be
               estimated initially by reference to the PFA Budget.  EPFAL shall
               adjust the amount of each such  payment by  reference to the most
               recent Statement of Costs and Fees and so as to take into account
               PFA Operating Costs, the PFA Handling Charge,  the Annual Fee 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  actual and  anticipated PFA  Operating  Costs,  the PFA
               Handling Charge, the Annual Fee and the 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 interim  basis of such  amount  as the  Executive
               Committee  estimates to 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 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 collect from Pool Members the amounts they are obliged to pay by
         way of bank transaction charges towards the costs of the Pool Banker
         and all Settlement Banks ("Bank Charges") and shall account for the
         same to the Pool Banker and such Settlement Banks.

17.      ALLOCATION OF CHARGES

17.1     Total Sum Due: In respect of each PFA Accounting Period, the Total Sum
         Due shall be allocated amongst Pool Members in accordance with the
         following provisions of this Section 17.

17.2     Payment of Total Sum Due: Each Pool Member shall be obliged to pay the
         amount allocated to it in accordance with this sub-section. The total
         aggregate amount allocated to all Pool Members in respect of any PFA
         Accounting Period shall equal the Total Sum Due in respect of such PFA
         Accounting Period.

          17.3 Allocation of Total Sum Due: The Total Sum Due in respect of each
               PFA Accounting  Period shall be allocated amongst Pool Members in
               the following manner:-

         17.3.1     first, in order to recover the discrete costs referable to
                    each Pool Member during any PFA Accounting Period, the costs
                    incurred by EPFAL in its capacity as the Pool Funds
                    Administrator in complying with a request of such Pool
                    Member made pursuant to Clause 63.1.7 or sub-section 6.3 of
                    Schedule 11 which are directly referable to such Pool Member
                    shall, as far as possible, be allocated to such Pool Member;
                    and

          17.3.2  secondly,  100 per cent. of the  balance of the Total Sum Due
               during  any PFA  Accounting Period  not  recovered  pursuant  to
               paragraph  17.3.1  shall be allocated  amongst all Pool  Members
               during such PFA Accounting Period  according to their respective
               Contributory  Shares  or such PFA  Accounting  Period.  For this
               purpose,  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 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.

18.      ADJUSTMENT

         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 in the amount of the Base
         Sum to be used in the calculation of the Annual Fee for the duration of
         the additional period referred to in sub-section 3.1. If EPFAL and the
         Executive Committee shall agree to revise the amount of the Base Sum,
         such revision (and any consequential revision in the Annual Fee) shall
         take effect in accordance with the terms of that agreement. 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 Commencement 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 detailed in the
         Agreement as at the PFA Commencement 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 Base Sum to reflect such increase in EPFAL's duties,
                    responsibilities and liabilities as the Pool Funds
                    Administrator;

         19.2.3     if EPFAL and the Executive Committee shall agree an increase
                    in the Base Sum, such increase 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.

         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 paragraph 6) if

         configured in the same manner as is prescribed in one of the line
         diagrams contained in the relevant Agreed Procedure and fulfils all the

                    originates with the location at which the demand is taken,
                    which Specified Assets and Equipment are all owned by the
                    Applicants and/or are Specified Assets and Equipment in
                    respect of which a contribution is or will be made by the
                    Applicants to the provision and installation or maintenance
                    and repair costs thereof or where such Specified Assets and

                    relating to both 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 paragraph 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 paragraph 6) if the
     Nominated  Site shall be treated as a Trading  Site  having  regard to the
     criteria set out in paragraph 5.2.

5.2      The criteria referred to in paragraph 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;

         (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 an 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 paragraph 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 paragraph 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 paragraph 2F of Appendix 6 to, Schedule 9.

         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 Section

         3.1        the Statement of Costs is in agreement with the underlying
                    books and records of the Ancillary Services Provider; and

         3.2        Total Operating Costs and Depreciation have been properly
                    extracted from the audited financial statements.

         Executive may agree with the auditors of the Ancillary Services
         Provider.

         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 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

         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 Section 5.2 is
         likely to be 10 per cent. more or less than the amount to which it is
         entitled under Section 5.1 it shall, with the consent of the Executive
         (such consent not to be unreasonably withheld or delayed), revise as
         appropriate the estimate made in accordance with 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 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 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

                    may take into  account  in any ASP  Budget or  Statement  of

                    corporate overhead charges payable by the Ancillary Services
                    Provider  to its  immediate  holding  company  or any  other

         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.

         1.3.3      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 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 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 paragraph, 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 fourteen 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
                          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 Schedule
                         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

                         obligations which are expressly set out or referred to
                         in   this   Schedule    (including   those  provisions
                         incorporated  herein by reference in paragraph 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
                         paragraph 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
                         paragraph  24) or are  definitions listed in paragraph
                         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 paragraph 24 shall be deemed to be not set out
                    in this Schedule) or which is not a definition listed in
                    paragraph 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 or the Pool Funds Administrator) is also not
                    required under this Agreement to such modification,
                    abrogation, amendment or suspension.

                    2.2.3A Meter  Operator Party whose consent or approval need
                         not by virtue of this paragraph 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  paragraph 1.4 (and such
                         that  the provisions  of that  paragraph  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 paragraphs
                         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,  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 the  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  paragraph  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.

                          3.3.2 and has referred the matter to the Director in
                          accordance with paragraph 3.4.

                    (b)   the Executive Committee shall have failed to notify

                          Meter Operator Party should be admitted as a Meter
                          Operator Party, the New Meter Operator Party shall be
                          admitted and the provisions of paragraph 3.5 shall
                          apply.

                          Operator Party consequent upon such application (but
                          without prejudice to any new application it may make
                          thereafter).

                    For the purposes of paragraph (a) above the Meter Operator
                    Party shall not be deemed to be unable to pay its debts if
                    any such demand as is mentioned in the said section is being
                    contested in good faith by the Meter Operator Party with
                    recourse to all appropriate measures and procedures.

         For the avoidance of doubt, the Parties and Meter Operator Parties
         hereby acknowledge and agree that a resolution of the Executive
         Committee to remove the Operator as Operator or a Meter Operator Party
         as Meter Operator Party shall not, of itself, constitute good cause.

6.4      Referral to the Director: An Operator or, as the case may be, a Meter
         Operator Party may in writing within the 28 day period referred to in
         paragraph 6.2(b) refer a decision of the Executive Committee to remove

         prejudice to all past, present and future accrued and accruing rights
         and liabilities of that Party as Party in any capacity whatsoever other
         than as Meter Operator Party.

6.12     Paragraph exhaustive: The Parties and Meter Operator Parties agree that
         the foregoing provisions of this paragraph 6, when read with the
         provisions referred to in this paragraph, are exhaustive of cessation
         as a Meter Operator Party and of cessation of rights and liabilities as
         a Meter Operator Party.

                                       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 Metering System which is
                    registered with the Settlement System Administrator.

         7.1.2      All Metering Systems at the site of a Non-Pooled Generator,
                    which are part of the same Metering Equipment, must have the
                    same Operator.

         7.1.3Each Operator  shall ensure there is installed a 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.

          7.1.4To 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 paragraph 21.9(a)),  the Grid
               Code or any Distribution Code.

7.2      Description of Metering Equipment:

         7.2.1      Metering Equipment and its component parts shall comply, as
                    a minimum, with the requirements referred to or set out in
                    any relevant Code of Practice or shall be the subject of,
                    and comply with, a dispensation agreed in accordance with
                    paragraph 14.

         7.2.2      Metering Equipment comprising a Metering System shall use
                    such communication protocols selected, with the approval of
                    the Settlement System Administrator, as appropriate for that
                    Metering Equipment from a list of communication protocols
                    approved and maintained from time to time by the Settlement
                    System Administrator.

7.3      Accuracy of Metering Equipment:

         7.3.1      The Metering Equipment comprising any Metering System shall
                    be accurate within the prescribed limits for such Metering
                    Equipment referred to or set out in the relevant Code of
                    Practice except only in the case where such Metering
                    Equipment is the subject of, and complies with, a
                    dispensation relevant to those prescribed limits agreed in
                    accordance with paragraph 14.

         7.3.2      The accuracy limits referred to in the relevant Code of
                    Practice shall be applied after adjustments have been made
                    to Metering Equipment to compensate for any errors 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
                    the Metering Equipment. Such levels of accuracy will, in the
                    event of any uncertainty or dispute, be specified by the
                    Executive Committee.

          7.4  Calibration  of Metering  Equipment:  Each Operator  shall ensure
               that  all  Metering   Equipment  which  is  registered  with  the
               Settlement  System  Administrator  pursuant to this Agreement and
               for  which it is  Operator  pursuant  to this  Schedule  shall be
               calibrated in order to meet the accuracy requirements referred to
               in paragraph  7.3.1 and otherwise in accordance with the relevant
               Code of Practice or, where appropriate, any relevant dispensation
               agreed in accordance  with paragraph 14. Subject to paragraph 21,
               the Settlement System Administrator and the Pool Auditor shall be
               granted access to all such Metering Equipment and any other Plant
               or  Apparatus  on any Site in order to  inspect  the basis of any
               adjustments made to Metering Equipment.

8.       MAINTENANCE OF METERING EQUIPMENT

8.1      Proper order: Each Operator shall at its own cost and expense (but
         without prejudice to its right to charge any other person for such
         service pursuant to another agreement or arrangement) keep in good
         working order, repair and condition all Metering Equipment in respect
         of which it is the Operator to the extent necessary to allow the
         correct registration, recording and transmission of the requisite
         details of the quantity of Active Energy and/or Reactive Energy
         measured by the relevant Meter.

8.2      Inspection and Testing:

          8.2.1No 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  in respect of
               which it is the  Operator.  The  Operator  shall also carry out a
               test of the  accuracy  of all  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 which an Operator
                          is required to maintain for the purposes of this
                          Schedule is not performing within the prescribed
                          limits of accuracy referred to in paragraph 7.3.1; or

                    (b)   such Operator or any other Party or Meter Operator
                          Party has reason to believe there is any such failure
                          to so perform,

                    then, in the case of (b), such Operator, such other Party or
                    such Meter Operator Party shall notify the Settlement System
                    Administrator, the Registrant of the relevant Metering
                    System and the Host PES (if any) and, in any case, the
                    Settlement System Administrator:-

                    (i)   shall (if so requested by any Party or Meter Operator
                          Party) and (in any other case) may, without giving
                          notice to the relevant Operator or Registrant, inspect
                          such Metering Equipment and make such tests as the
                          Settlement System Administrator shall deem necessary
                          to determine its accuracy; or

                    (ii)  in any other circumstances require the relevant
                          Operator promptly to test the accuracy of the same but
                          in any event within 24 hours of receiving notification

                    Second Tier Customer or ERS First Tier Customer at the Site
                    in respect of which such access rights are required until
                    such access rights have been obtained and if supplying such
                    Second Tier Customer or ERS First Tier Customer at such Site
                    to cease forthwith to supply such Second Tier Customer or
                    ERS First Tier Customer at that Site;

         (ii)       hereby undertakes not to take any future supply of
                    electricity from such Non-Pooled Generator at the Site in
                    respect of which such access rights are required until such

                    exercising such right of access and procedures for obtaining
                    the same;

         (v)        the means of communication to the Meter Operator Party or,
                    as the case may be, Party (and all employees and/or
                    contractors who may be authorised from time to time to
                    exercise such right of access) of any relevant directions or
                    regulations made by the Meter Operator Party or, as the case
                    may be, Party; and

                    that all persons exercising any right of access on behalf of
                    such Party or Meter Operator Party) observe and perform any
                    such arrangements and all provisions (or directions or
                    regulations issued pursuant thereto) made from time to time.

21.8     Damage: Each Party or Meter Operator Party shall procure that all
         reasonable steps are taken in the exercise of any right of access by or
         on behalf of such Party or Meter Operator Party to:-

         (a)        avoid or minimise damage in relation to any Meter Operator
                    Party's, Party's, Second Tier Customer's, ERS First Tier
                    Customer's, Non-Pooled Generator's or other Third Party's
                    property; and

         (b)        cause as little disturbance and inconvenience as possible to
                    any Meter Operator Party, Party, Second Tier Customer, ERS

                                                    PART 10

                                           COMMUNICATIONS EQUIPMENT

22.      COMMUNICATIONS EQUIPMENT

22.1 Compatibility:  Communications  Equipment at or relating to any Site (which
     whenever used in this paragraph 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 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  at or relating to a Site is used for
     purposes  other than in  connection  with  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 paragraph 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
                    accordance with the relevant Tariff and payable in respect
                    of Communications Equipment installed and maintained at or
                    relating to such Site by such Tariff Operator for the
                    purposes of this Agreement.

          (b)  The Settlement  System  Administrator shall recover from time to
               time (for credit to Pool Members as the Executive Committee shall
               from time to time direct) from a Tariff  Operator  and a Tariff
               Operator shall pay from time to time (for credit to Pool Members
               as the Executive Committee shall from time to time direct) to the
               Settlement System Administrator in respect of the costs of manual
               on-site interrogation or data estimation costs incurred by it in
               respect  of  each  Site at  which  there  is not  installed and
               maintained   Communications Equipment  in  accordance  with  the
               requirements  of this Schedule, such amounts (if any) determined
               in  accordance  with the relevant  Tariff.  Where the Settlement
               System  Administrator  has received any such payment pursuant to
               this  sub-paragraph  22.3(b) it shall be set off in full against
               amounts  which  may  be  recovered  by  the   Settlement System
               Administrator pursuant to paragraph 22.6 or 22.7.

         (c)        The Settlement System Administrator may, and at the
                    direction of the Executive Committee shall, without notice
                    to the relevant Tariff Operator set off amounts payable to
                    it by that Tariff Operator under the relevant Tariff against
                    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
                    paragraph 22.3 shall be deemed to have been received by the
                    Settlement System Administrator for the purposes of
                    paragraph 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 paragraph 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 paragraph 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.

22.7 Recovery  of  costs:  All costs  and xpenses relating  to  the  payment
     arrangements referred  to  in  this  Schedule  for the  installation and
     maintenance of Communications Equipment, the relevant Tariff or otherwise,
     including payments which are made to Tariff Operators for the provision of

23.1     Transitional Arrangements: With effect from the date this Schedule
came into effect (the "NSD Date")
                                    --------
         each Party which is at that date an Operator or a Potential Operator
         shall be deemed to be a Meter Operator Party (in addition to continuing
         as a Party in any other capacity) and to have complied with all the
         requirements of or referred to in this Schedule 21 relating to
         admission as a Meter Operator Party and as an Operator. Such Parties
         are more particularly described in Annex 4 hereto. The Parties
         acknowledge and confirm that the deemed admission of an existing Party
         as a Meter Operator Party shall not affect that Party's rights and
         obligations under any agreement or arrangement relating to being an
         Operator entered into or existing between the Parties or any of them
         prior to such deemed admission, and that accordingly such agreement or
         arrangement shall continue notwithstanding the change and any reference
         to that Party being an Operator under this Agreement shall be construed
         as being an Operator as a Meter Operator Party.

23.2 Saving:  Notwithstanding  paragraph 23.1, each Party to which this Part 11
     applies expressly acknowledges and agrees that, notwithstanding any deemed
     satisfaction of the conditions which are required to be fulfilled as at the
     NSD Date in accordance with this Schedule for the purposes of admission as
     a Meter Operator Party and as Operator,  it shall be subject (but only with
     prospective  effect; that is to say to the effect that any conditions which
     apply as at the NSD Date are  deemed to be  fulfilled  and need not then be
     fulfilled  as a  continuing  obligation)  to  the  continuing  and  further
     conditions  for  registration  as an Operator  from time to time and to the
     provisions of paragraph 4.4, and that it shall be subject to the provisions
     for the  resignation, removal and  cessation as Operator in respect of any
     Metering  System,  or as Meter Operator  Party,  as the  case  may be,  in
     accordance  with the  provisions of this Schedule as at the date hereof and
     from time to time, and after any such resignation,  removal or cessation as
     a Meter Operator  Party,  it shall be subject in full to the procedures for
     admission  as a Meter  Operator  Party and  Operator as may be set out from
     time to time in this Schedule.

                         advance  of any meeting  of the  teering  Group,  for
                         approval. Each Funding Tranche shall contain details of
                         the scope of the work proposed to be  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 subject of a Funding Tranche or Funding Tranches
                         to be submitted to the Steering  Group (with a copy to
                         all PES Nominees) by the Programme Board or any member
                         of 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.

                    3.4.3At 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.

                    3.4.4As 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 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
                         4.3.2 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.

4.       THE OPERATIONAL FRAMEWORK

         4.1      Changes to Operational Framework: Subject to sub-section 4.2,
                  any 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).

5.       PROGRAMME BOARD AND PROGRAMME BUDGET

         5.1      Constitution of the Programme Board: At all times, the
                  Programme Board shall comprise three senior users, one senior

               approval  of the draft  programme  budget  shall  follow that for
               approval of Funding 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
               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

                    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:

                  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:

                                   ACL = T1998 PC + FC; and

                  8.1.3 if Total 1998 Programme Costs are greater than the Upper
Limit then:

                                   [OBJECT OMITTED]

               Financing  Costs, over a  maximum  period  of 5 years  from  the
               Implementation Date from all suppliers of customers  below 100kW
               on the basis of a charge per megawatt hour  supplied. The Public
               Electricity  Suppliers  shall be  entitled to recover the ACL in
               proportion to the 1998 Programme  Costs contributed by them (the
               Public  Electricity Suppliers'  proportions being grossed up for

               Implementation  Date is later than 1st April,  1998,  the Public
               Electricity  Suppliers or their agents will be able to recover a
               proportionately lesser amount.

                  8.2.2   If, by reason of force majeure (which for these
                          purposes means any delay as a result of the
                          requirements of the Director or the Secretary of State
                          or any exceptional circumstances outside the control
                          of the Pool), the 1998 Programme is delayed or not
                          implemented, full cost recovery of the ACL shall be
                          made.

                  8.2.3   The principles for recovery set out in this
                          sub-section 8.2 require further detailed drafting.
                          Pool Members undertake to use their reasonable
                          endeavours to agree the detailed drafting by 1st June,
                          1997.

         8.3      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).

                         the Required Documentation and the Pool 1998 Software;

                          (ii)     the Scots Licensees shall within 30 days of
                                   termination deliver to the Executive

                                   the Pool 1998 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 Software and any copies of them;

                          (iii)    the Scots Licensees will destroy any
                                   programme or other series of instructions
                                   contained in any memory device which is
                                   derived from the Required Documentation
                                   and/or the Pool 1998 Software and is in their
                                   possession or control.

                  (C)     Termination of the Scots 1998 Licence will not release
                          any of the Scots Licensees from any obligations
                          arising prior to termination or which expressly or by
                          implication become 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
                         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  equired
                         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 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 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.

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 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 the 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.

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
               paragraph 6.1(B).

(B) The terms referred to in paragraph 6.1(A) are that the entry into and
performance of the Scots Contract, either in itself or in conjunction with the
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 the Scottish PESs or Scottish Settlements from
                  employing or retaining 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.

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 of those expert and systems delivery user
                  groups established under the 1998 Programme which are of
                  direct relevance to the Scottish Settlements Project.

         7.2      1998 Contractor relationship:

               (A)  The Scottish PESs and Scottish Settlements shall not contact
                    or  communicate directly  with,  or place any order with or
                    give any instruction to, any 1998 Contractor with respect to
                    any matter concerning the 1998 Programme,  the 1998 Systems,
                    the  Required  Documentation  or the Pool 1998  Software but
                    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)
                    below, to place orders 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 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).

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-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.

                              required disclosure to the Accreditation

                     administration of the Accreditation Process to the
                     Accreditation Administrator. For the avoidance of doubt,
                     this shall not include the taking of any decision as to
                     whether the Agency Systems of an Applicant (or any of them)
                     should be Certified or the Applicant should be Accredited.

                         as the Accreditation Authority, the Executive Committee

                         Accredited  person  and  shall not rely on the fact of
                         Accreditation  (or the lack of Accreditation)  as,  or

                         statement   or   indication   on  the part of  the
                         Accreditation  Authority,  the  Accreditation
                         Administrator  or  the  Certification  Agent that  the
                         Accredited  person has any or any particular financial
                         condition  or  prospects  or  level  of  management or
                         operational ability.

          PART 5 : THE CERTIFICATION PROCESS AND ACCREDITATION PROCESS

5.1      The Certification Process and Accreditation Process:

         5.1.1    The Certification Process and the Accreditation Process shall
                  be conducted in accordance with Agreed Procedure 531.

         5.1.2    Agreed Procedure 531 shall not conflict with the provisions of
                  this Schedule and, to the extent of any conflict or
                  inconsistency between the two, the provisions of this Schedule
                  shall prevail.

         5.1.3    The Accreditation Authority shall provide copies of the latest
                  version of this Schedule and Agreed Procedure 531 to
                  Applicants.

         5.1.4    The Accreditation Authority shall, subject to sub-section 6.2,
                  provide each Applicant with a copy of all opinions (whether
                  preliminary or final) of the Certification Agent in relation
                  to the Agency System(s) of that Applicant delivered pursuant
                  to paragraph 4.3.4 at the same time as the Accreditation
                  Authority notifies such Applicant whether its Agency System(s)
                  has (have) been Certified and/or (as the case may be) such
                  Applicant has been Accredited. The Accreditation Authority
                  shall be under no obligation to provide an Applicant with a
                  copy of any such opinion at any time before it gives such
                  notification.

5.2      No Certification: The Accreditation Authority shall not Certify the
         Agency System of any Applicant unless the Certification Agent has
         provided an opinion (not being a disclaimer of opinion, howsoever
         called) in the terms of paragraph 4.3.4 in relation to that Agency
         System.

5.3      Loss of Certified or Accredited status: The Accreditation Authority
         shall have the right at any time and from time to time in accordance
         with Agreed Procedure 531:

         5.3.1    to remove the Certification of all or any of the Agency
                  Systems of any person, whereupon such Agency System(s) shall
                  cease to be Certified; and/or

         5.3.2    to remove the Accreditation of any person, whereupon such
                  person shall cease to be Accredited.

5.4      Re-certification: Each person who has been Accredited shall be required
         to have some or all of its Agency Systems re-Certified in accordance
         with Agreed Procedure 531. If any such Agency System is not so
         re-Certified, such person's Accreditation shall automatically lapse.

5.5      Fees and expenses:

         5.5.1    The Accreditation Authority shall determine and publish to
                  Applicants and to those persons who have been Accredited a
                  Menu of Certification Fees which shall be charged directly to
                  Applicants for the purposes of Certification, and the
                  Accreditation Authority shall have the right to revise such
                  fees from time to time.

         5.5.2    Each Applicant shall pay its own costs and expenses incurred
                  in connection with the Certification Process and the
                  Accreditation Process.

5.6      Applicants bound by this Schedule: Applicants shall agree to be bound
         by the Certification Process, the Accreditation Process, the provisions
         of this Schedule and Agreed Procedure 531 by the execution of a letter
         agreement in form and content satisfactory to the Accreditation
         Authority.

5.7  Appeal procedure: If an Applicant is dissatisfied for any reason (including
     on the grounds that the Applicant disagrees with the final opinion of the
     Certification  Agent in relation to one or more of its Agency Systems) with
     the decision of the  Accreditation Authority as to whether such  Applicant
     shall be Accredited,  the sole and exclusive remedy of the Applicant shall
     be to refer the matter for determination to the Director in accordance with
     Agreed  Procedure  531. The determination  of the Director shall be final,
     conclusive and binding on the Applicant,  the  Accreditation Authority and
     all Pool Members.

5.8      Exclusion of other appeals:

         5.8.1    For the avoidance of doubt, neither Clause 83 nor Clause 84
                  shall apply in the case where an Applicant is dissatisfied for
                  any reason with the decision of the Accreditation Authority as
                  to whether such Applicant shall be Accredited. Sub-section 5.7
                  provides the sole and exclusive remedy of the Applicant.

         6.1.2            (a) completion of all documentation by or on behalf of
                          the Applicant in connection with the Certification

                          documentation and provide all the information required
                          thereunder within the time periods prescribed by
                          Agreed Procedure 531; and

                  (c)     the Applicant has had the opportunity to take its own
                          legal and other professional advice regarding the

                  to the Applicant's business records, working papers and

                  or any oral or written advice given in relation to, any such
                  working papers, opinion, report or other documentation by) the
                  Accreditation Authority, the Accreditation Administrator or
                  the Certification Agent in connection with the Certification
                  Process or the Accreditation Process unless such working
                  papers, opinion, report or other documentation is expressly
                  addressed to such Applicant; and

         6.2.2    it shall keep confidential on the terms set out in Clause 70
                  any working papers, opinions, report or other documentation
                  referred to in paragraph 6.2.1 unless such working papers,
                  opinion, report or other documentation is expressly addressed
                  to such Applicant.

                                       PART 7 : LIMITATION OF LIABILITY

7.1      Limitation of liability: Each Applicant, each person who has (or whose
         Agency Systems have) been Certified or Accredited (or whose
         Certification or Accreditation has been removed) and each Pool Member
         (each an "Interested Person") agrees that:

         7.1.1    the total aggregate liability of the Accreditation Authority
                  and the Accreditation Administrator to any Interested Person
                  whether in contract, tort (including negligence or breach of
                  statutory duty) or otherwise arising directly or indirectly
                  for or in connection with the Certification Process or the
                  Accreditation Process (including the contents of any opinion
                  or report prepared by the Accreditation Authority or the
                  Accreditation Administrator) shall in no circumstances exceed
                  (pound)5,000,000;

         7.1.2    neither the Accreditation Authority nor the Accreditation
                  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 from or
                  in connection with the Certification Process or the
                  Accreditation Process;

     7.1.3sub-sections  7.1 and 7.2  shall  not  exclude  the  liability of the
          Accreditation Authority or the Accreditation Administrator for fraud;

         7.1.4    the exclusions from and limitations of liability of the
                  Accreditation Authority and the Accreditation Administrator
                  under this section shall not apply to death or personal injury
                  caused by the negligence of the relevant one of the
                  Accreditation Authority or the Accreditation Administrator;

         7.1.5    the exclusions from and limitations of liability of the
                  Accreditation Authority and the Accreditation Administrator
                  under this Section 7 are reasonable because of (amongst other
                  matters) the likelihood that the amount of damages awardable
                  to the Interested Person from the Accreditation Authority or
                  the Accreditation Administrator would otherwise be
                  disproportionate to the charges which it makes in connection
                  with the Certification Process or the Accreditation Process
                  and because of the limited resources and expertise of the
                  Accreditation Authority and the Accreditation Administrator;

         7.1.6    the exclusions from and limitations of liability of the
                  Accreditation Authority and the Accreditation Administrator
                  under this Section 7 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; and

         7.1.7    the exclusions from and limitations of liability of the
                  Certification Agent are set out in the terms of its engagement
                  referred to in sub-section 4.1 and shall apply to this
                  Schedule as if the same were set out in full herein.
  PART 8 : DISAPPLICATION PROVISIONS

8.1      Disapplication:

         8.1.1    Parts III and V of this Agreement shall not apply in or to
                  this Schedule except, in the case of Part III, in respect of
                  any action under this Schedule which Pool Members in general
                  meeting are entitled or required by the terms of this Schedule
                  to take.

         8.1.2    If, and for long as, the Pool Auditor is also appointed as the
                  Certification Agent, the provisions of Clause 48.11 shall
                  apply.".

or by law;

                              (ii) in order for his employer to comply with the

                              in any of which events the Committee Member shall
                              first be required to give written notice of the
                              required disclosure to the Accreditation

                     administration of the Accreditation Process to the
                     Accreditation Administrator. For the avoidance of doubt,
                     this shall not include the taking of any decision as to
                     whether the Agency Systems of an Applicant (or any of them)

          and  prospects  and the  management  and  operational  ability of any
          Accredited person and shall not rely on the fact of Accreditation (or
          the lack of Accreditation) as, or infer therefrom, any representation,
          warranty  or other  statement  or  indication  on  the  part of  the
          Accreditation Authority,  the  Accreditation   Administrator or  the
          Certification Agent  that  the  Accredited  person  has  any  or any
          particular financial condition or prospects or level of management or
          operational ability.

                  an opinion of the Certification Agent addressed to the

          PART 5 : THE CERTIFICATION PROCESS AND ACCREDITATION PROCESS

The Certification Process and Accreditation Process:

         5.1.1    The Certification Process and the Accreditation Process shall
                  be conducted in accordance with Agreed Procedure 531.

         5.1.2    Notwithstanding paragraph 5.1.1, in reaching its decision as
                  to whether the Agency Systems of an Applicant (or any of them)
                  should be certified or an Applicant should be Accredited, the
                  Accreditation Authority shall be required to give effect to
                  any instruction given to it by Pool Members in general meeting
                  (whether of general application to the Certification Process
                  or the Accreditation Process or specific to one or more Agency
                  Systems or Applicants) and to any determination made by Pool
                  Members in general meeting with respect to the Accreditation
                  Requirements or the Certification Requirements.

         5.1.3    Agreed Procedure 531 shall not conflict with the provisions of
                  this Schedule and, to the extent of any conflict or
                  inconsistency between the two, the provisions of this Schedule
                  shall prevail.

         5.1.4    The Accreditation Authority shall provide copies of the latest
                  version of this Schedule and Agreed Procedure 531 to
                  Applicants.

         5.1.5    The Accreditation Authority shall, subject to sub-section 6.2,
                  provide each Applicant with a copy of all opinions of the
                  Certification Agent in relation to the Agency System(s) of
                  that Applicant delivered pursuant to paragraph 4.3.4 at the
                  same time as the Accreditation Authority notifies such
                  Applicant whether its Agency System(s) has (have) been
                  Certified and/or (as the case may be) such Applicant has been
                  Accredited. The Accreditation Authority shall be under no
                  obligation to provide an Applicant with a copy of any such
                  opinion at any time before it gives such notification.

         5.1.6    The Accreditation Authority shall make available to the
                  Director all information held by the Accreditation Authority
                  which the Director reasonably requires for the purposes of
                  making any determination pursuant to sub-section 5.7.

No       Certification: The Accreditation Authority shall not Certify the Agency
         System of any Applicant unless the Certification Agent has provided an
         opinion (not being a disclaimer of opinion, howsoever called) in the
         terms of paragraph 4.3.4 in relation to that Agency System.

38.3 Loss of Certified or Accredited status: The Accreditation Authority shall
have the right at any time and from time to time in accordance with Agreed
Procedure 531:
         5.3.1    to remove the Certification of all or any of the Agency
                  Systems of any person, whereupon such Agency System(s) shall
                  cease to be Certified; and/or

         5.3.2    to remove the Accreditation of any person, whereupon such
                  person shall cease to be Accredited.

Re-certification: Each person who has been Accredited shall be required to have
         some or all of its Agency Systems re-Certified in accordance with
         Agreed Procedure 531. If any such Agency System is not so re-Certified,
         such person's Accreditation shall automatically lapse.

38.5   Fees and expenses:
         5.5.1    The Accreditation Authority shall determine and publish to
                  Applicants and to those persons who have been Accredited a
                  Menu of Certification Fees which shall be charged directly to
                  Applicants for the purposes of Certification, and the
                  Accreditation Authority shall have the right to revise such
                  fees from time to time.

         5.5.2    Each Applicant shall pay its own costs and expenses incurred
                  in connection with the Certification Process and the
                  Accreditation Process.

Applicants bound by this Schedule: Applicants shall agree to be bound by the
         Certification Process, the Accreditation Process, the provisions of
         this Schedule and Agreed Procedure 531 by the execution of a letter
         agreement in form and content satisfactory to the Accreditation
         Authority.

38.7   Referral to the Director:
         5.7.1    The sole and exclusive remedy of an Applicant who is
                  dissatisfied with the decision of the Accreditation Authority
                  to refuse to Accredit such Applicant (the "Dissatisfied
                  Applicant") shall be to refer the matter to the Director in
                  accordance with this sub-section 5.7 for determination.

         5.7.2 To be a valid referral pursuant to paragraph 5.7.1, the
Dissatisfied Applicant must:

                  (a)     refer the matter for determination to the Director in
                          writing (with a copy to the Accreditation Authority)
                          no later than 14 days after receipt by the
                          Dissatisfied Applicant of the decision of the
                          Accreditation Authority refusing to Accredit it; and

                  (b)     set out in its referral to the Director (with reasons
                          in support) the ground or grounds on which the
                          Dissatisfied Applicant is making its application to
                          the Director which shall be one or more of the
                          following (and no other):

                          (i)      that the Accreditation Authority has not
                                   followed the procedures set out in this
                                   Schedule and Agreed Procedure 531 in
                                   considering whether the Dissatisfied
                                   Applicant should be Accredited; or

                          (ii)     that the Accreditation Authority has given
                                   undue weight to particular evidence submitted
                                   or to the lack of particular evidence in
                                   connection with the Dissatisfied Applicant's
                                   application for Accreditation; or

                          (iii)    that the Accreditation Authority 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 Accreditation
                                   Authority as to how it is to assess and
                                   decide Applications, the Accreditation
                                   Authority should not have taken into account
                                   the failure by the Dissatisfied Applicant to
                                   satisfy one or more specified Accreditation
                                   Requirements.

         5.7.3    On a valid referral pursuant to paragraph 5.7.1 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 5.7.4, the practice and
                  procedure to be followed in connection with any such
                  determination shall be such as the Director may consider
                  appropriate.

         5.7.4    In connection with any referral pursuant to paragraph 5.7.1
                  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 be Accredited
                          notwithstanding that the ground on which the
                          Dissatisfied Applicant has applied to the Director is
                          either the wrong ground or has not been proven.

         5.7.5    The determination of the Director or, as the case may be, the
                  arbitrator pursuant to paragraph 5.7.3 shall be final,
                  conclusive and binding on the Dissatisfied Applicant, the
                  Accreditation Authority 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 Applicant, the Accreditation Authority and all
                  Pool Members shall promptly give effect to any such
                  determination.

         5.7.6    For the avoidance of doubt, neither Clause 83 nor Clause 84
                  shall apply in the case where an Applicant is dissatisfied
                  with the decision of the Accreditation Authority to refuse to
                  Accredit such Applicant. This sub-section 5.7 provides the
                  sole and exclusive remedy of a Dissatisfied Applicant. Parties
                  and Applicants shall not use, or seek to use, those Clauses or
                  any other provisions of this Agreement to thwart or challenge
                  referrals to the Director pursuant to paragraph 5.7.1.

Exclusionof other appeals: Save for any reference to the Director in accordance
         with sub-section 5.7, in respect of any matter concerning the
         Certification of any particular Agency Systems or the Accreditation of
         any person all reference or appeal procedures in this Agreement to or
         involving the Director are expressly excluded.

                                     PART 6 : APPLICANT'S RESPONSIBILITIES

Applicant's warranty and undertakings: Each Applicant represents, warrants and
         undertakes to each of the Pool Members (for itself and as trustee and
         agent for the Accreditation Authority, the Accreditation Administrator
         and the Certification Agent) that:

         6.1.1    all information supplied by or on behalf of the Applicant to
                  the Accreditation Authority, the Accreditation Administrator
                  or the Certification Agent in connection with the

                  complete and accurate and not misleading because of any
                  omission or ambiguity or for any other reason, subject to
                  disclosure, if any, acceptable to the Accreditation Authority
                  being made in advance of the provision of the relevant
                  information to the Accreditation Authority, the Accreditation
                  Administrator or (as the case may be) the Certification Agent;

         6.1.2            (a) completion of all documentation by or on behalf of
                          the Applicant in connection with the Certification
                          Process or the Accreditation Process is and will
                          remain the sole responsibility of the Applicant;

                  (b)     the Applicant will duly complete all such
                          documentation and provide all the information required
                          thereunder within the time periods prescribed by
                          Agreed Procedure 531; and

                  (c)     the Applicant has had the opportunity to take its own
                          legal and other professional advice regarding the
                          Certification Process and the Accreditation Process;

         6.1.3    it will confirm in writing to the Accreditation Authority (for
                  itself and on behalf of all Pool Members, Accreditation
                  Authority and the Certification Agent) in accordance with
                  Agreed Procedure 531 that each of the other representations,
                  warranties and undertakings in this sub-section 6.1 are true
                  and have been complied with as at the date on which it has
                  been notified that its application(s) for Certification and/or
                  Accreditation will be considered by the Accreditation
                  Authority; and

         6.1.4    the Applicant will co-operate fully with the Accreditation
                  Authority, the Accreditation Administrator and the
                  Certification Agent in the Certification Process and the
                  Accreditation Process and, without prejudice to the generality
                  of the foregoing, shall permit each of them reasonable access
                  to the Applicant's business records, working papers and
                  employees for the purposes of each such process upon not less
                  than three working days' advance notice.

No reliance by Applicant: The Applicant acknowledges and agrees that:

         6.2.1    it shall not, and shall not be entitled to, place any reliance
                  on any working papers, opinion, report or other documentation
                  prepared by or for (or any oral or written interpretation of,
                  or any oral or written advice given in relation to, any such
                  working papers, opinion, report or other documentation by) the
                  Accreditation Authority, the Accreditation Administrator or
                  the Certification Agent in connection with the Certification
                  Process or the Accreditation Process unless such working
                  papers, opinion, report or other documentation is expressly
                  addressed to such Applicant; and

         6.2.2    it shall keep confidential on the terms set out in Clause 70
                  any working papers, opinions, report or other documentation
                  referred to in paragraph 6.2.1 unless such working papers,
                  opinion, report or other documentation is expressly addressed
                  to such Applicant.

                                       PART 7 : LIMITATION OF LIABILITY

         Limitation of liability: Each Applicant, each person who has (or whose
         Agency Systems have) been Certified or Accredited (or whose
         Certification or Accreditation has been removed) and each Pool Member
         (each an "Interested Person") agrees that:

         7.1      the total aggregate liability of the Accreditation Authority
                  and the Accreditation Administrator to any Interested Person
                  whether in contract, tort (including negligence or breach of
                  statutory duty) or otherwise arising directly or indirectly
                  for or in connection with the Certification Process or the
                  Accreditation Process (including the contents of any opinion
                  or report prepared by the Accreditation Authority or the
                  Accreditation Administrator) shall in no circumstances exceed
                  (pound)5,000,000;

         7.2      neither the Accreditation Authority nor the Accreditation
                  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 from or
                  in connection with the Certification Process or the
                  Accreditation Process;

         7.3      sub-sections 7.1 and 7.2 shall not exclude the liability of
 the Accreditation Authority or
                  the Accreditation Administrator for fraud;

         7.4      the exclusions from and limitations of liability of the
                  Accreditation Authority and the Accreditation Administrator
                  under this section shall not apply to death or personal injury
                  caused by the negligence of the relevant one of the
                  Accreditation Authority or the Accreditation Administrator;

               7.5  the  exclusions from and  limitations  of  liability of the
                    Accreditation Authority and the Accreditation Administrator
                    under this  Section 7 are  reasonable  because of (amongst
                    other  matters)  the  likelihood that the amount of damages
                    awardable to the  Interested Person from the Accreditation
                    Authority or the Accreditation Administrator would otherwise
                    be  disproportionate  to  the  charges  which  it makes in
                    connection   with   the   Certification   Process or   the
                    Accreditation  Process and because of the limited resources
                    and  expertise  of  the  Accreditation   Authority and  the
                    Accreditation Administrator;

         7.6      the exclusions from and limitations of liability of the
                  Accreditation Authority and the Accreditation Administrator
                  under this Section 7 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; and

         7.7      the exclusions from and limitations of liability of the
                  Certification Agent are set out in the terms of its engagement
                  referred to in sub-section 4.1 and shall apply to this
                  Schedule as if the same were set out in full herein.

                                      PART 8 : DISAPPLICATION PROVISIONS

         Disapplication:

         8.1      Parts III and V of this Agreement shall not apply in or to
                  this Schedule except, in the case of Part III, in respect of
                  any action under this Schedule which Pool Members in general
                  meeting are entitled or required by the terms of this Schedule
                  to take.

         8.2      If, and for long as, the Pool Auditor is also appointed as the
                  Certification Agent, the provisions of Clause 48.11 shall
                  apply.".

1.2      Reconciliation Statements

         Initial Reconciliation Statements

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

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

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

1.2.4    Invoices issued under paragraph 1.2.3 above and 1.2.5 below shall be
         payable on or before 3lst March in the Financial Year to which they
         relate.

1.2.5    In respect of the Financial Year:-

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

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

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

2.       Revision of Charges

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

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

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

3.       Replacement of NGC Assets

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

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

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

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

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

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

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

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

         (a)      keep the NGC Asset in service;  and

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

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

         If the Director determines that the Connection Charges payable in
         respect of such NGC Asset should be:-

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

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

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

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

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

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

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

4.       Termination Amounts

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

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

                                                             (a)    in respect
                          of NGC Assets:-

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

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

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

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

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

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

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

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

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

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

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

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

5.       Deductions

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

Part 2 - Transmission Services Use of System Charges

Introduction

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

1.       Reconciliation

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

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

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

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

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

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

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

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

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

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

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

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

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

1.3      The right to submit a Reconciliation Statement and consequential

         rating or a Letter of Credit or transfer to NGC cash to be credited to
         the Escrow Account.

2.       Credit Monitoring

2.1      Determination of Security Cover

         The amount of Security Cover which the User shall be required to

         Supplemental Agreement to which the User is a party shall be provided
         in an amount to be reasonably assessed by NGC as the aggregate amount
         reasonably anticipated by NGC as being payable by the User pursuant to
         all Supplemental Agreements to which the User is a party in respect of
         the Transmission Services Use of System Charges referred to in Part 2
         of Appendix D over a 28 day period.

2.3      Six Monthly Variation

         NGC shall keep under review the Security Cover relating to the User and

         pursuant to paragraph 2 of this Part 3.

2.5      Increase or Decrease of Security Cover

         If, after considering any representations which may be made by the
         User, NGC reasonably determines that the User's Security Cover should
         be increased or decreased, it shall so notify the User. If NGC so
         determines that such Security Cover should be decreased and the User
         consents then that reduction shall take place. NGC shall consent to an
         appropriate reduction in the available amount of any outstanding
         Qualifying Guarantee or Letter of Credit and/or shall repay to the User
         such part of the deposit held in the Escrow Account for the account of
         the User (together with all accrued interest on the part to be repaid)

         Security Cover applicable to it. If NGC so determines that the User's
         Security Cover should be increased, the User s hall, within five
         Business Days of notice as aforesaid, procure an additional or
         replacement Qualifying Guarantee or Letter of Credit or transfer to NGC

2.6      Notification in respect of Security Cover

         NGC shall notify the  User promptly if:-

                  2.6.1 the User fails to provide, maintain, extend or renew a

                  required to provide, maintain, extend or renew pursuant to
                  paragraphs 1 or 2;

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

                  2.6.3 NGC becomes aware that the User (a) s hall cease to have
                  an Approved Credit Rating, or (b) shall be placed on credit
                  watch by the relevant credit rating agency (or becomes subject

                  the User retaining an Approved Credit Rating, or (c) shall be
                  in default under the additional or alternative security
                  required to be provided pursuant to this Part 3; or

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

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

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

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

                  the Escrow Account to any other accounts of NGC at its
                  absolute discretion and shall notify the User accordingly;

                  (c) NGC may demand payment under any outstanding Letter of

                  is made within 14 days after notification by NGC pursuant to
                  paragraph 2.5.2, the change shall not come into effect until

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

                                    (b) if the determination of the Director is
                           that the proposed change does have a material adverse
                           effect upon the rights and liabilities as set out in
                           this Schedule of the TUG Parties as a group, the

                           proposed change is not to come into effect pursuant
                           to paragraph 2.5.4(b), the Director shall have no
                           authority to require any modifications to the

                           adverse effect or to require any other change.

                  2.5.5 If the Director does not make his determination within
                  28 days of receipt of a referral or, such other period as
                  shall have been agreed in writing by the Director and NGC, in

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

8.2      Marking of Voting Papers

         On receipt, each Industry Party shall mark the Voting Paper to rank the
         nominees in order of preference until these, are indifferent about the
         remaining candidates. Each Industry Party that is a member of an

         further part in the election process. NGC shall transfer the votes of
         all those Industry Parties who voted for that nominee to the nominee
         who is the next highest preference (and who has not already been
         eliminated) of such Industry Party or Industry Parties (as the case may
         be).

8.6      Re-ranking of Nominees

         until there are only 15 nominees left who will become the 15 Industry
         Party Representatives.

8.7      Equal Votes

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

9.       Voting by an Industry Party Group

9.1      NGC shall not be under any obligation to monitor or to ensure that

         Representative pursuant to paragraph 6.2.2 and if so, the name of the
         Representative.

11.      Notification of Industry Party Representatives

         payments to/from NGC (calculated in accordance with paragraph 2.3 of
         this Appendix 3) as follows:-

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

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

2.6      Reallocation of Votes

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

3.       Consumer Party Representatives

         In respect of Consumer Party Representatives votes shall be calculated
         by NGC in accordance with the following:-

         3.1      Vote Allocation

                  each Consumer Party   Representative   will  be  allocated
                  5,000.000 votes;

         3.2      Fewer than 3 Consumer Party Representatives

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

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

4.       OBLIGATORY REACTIVE POWER SERVICE - DEFAULT PAYMENT ARRANGEMENT

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

4.2      Subject always to paragraph 5, and notwithstanding

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

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

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

4.3  Save to the extent and for the duration of any Market Agreement (as defused
     in  sub-paragraph 5. 1) which may be entered into between NGC and a User as
     referred to in paragraph S:-

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

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

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

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

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

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

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

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

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

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

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

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

5.       OBLIGATORY REACTIVE POWER SERVICE AND ENHANCED REACTIVE POWER SERVICES
         - MARKET PAYMENT MECHANISM

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

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

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

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

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

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

         (a)      Relevant Dates

                           endeavours to agree the terms of. and enter into, the
                           Market Agreement as aforesaid, to notify the other
                           that it no longer wishes to enter into the Market
                           Agreement. whereupon the Tender in question shall be
                           deemed to be withdrawn.

                                    (ii) In the event of a deemed withdrawal of
                           a Tender in the circumstances set out in subparagraph

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

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

                         capability  for that  period in each  Relevant  Zone as
                         forecast by NGC ("the Total Forecast Capability"),

                             question, as given each year in the
                             Seven Year Statement,

                               provided that each Provisional Zonal Weighting
                               Factor (both leading and lagging) shall not
                               in any event be greater than 3.000 and
                               provided further that (for the avoidance of
                               doubt) no determination of ZWFlead, ZWFlag,
                               and TAN shall be made in respect of any such
                               twelve month period when Y = 0.

                  (b) The Provisional Zonal Weighting Factors, together with the
                  Total Forecast Capability, will be notified by NGC as soon as
                  reasonably practicable by publication in the first practicable
                  Seven Year Statement (or any update thereof).

         Reconciliation

         As soon as reasonably practicable following the expiry of each twelve
         month period ending 31st March, NGC shall recalculate ZWFlead and
         ZWFlag, for that twelve month period in accordance with the above
         provisions for calculation of the Provisional Zonal Weighting. Factors
         but substituting for the Total Forecast Capability the actual total
         leading or lagging (as the case may be) Mvar capability for that twelve
         month period in each Relevant Zone as determined by NGC ("the Total
         Actual Capability"). Such recalculation of ZWFlead and ZWFlag shall be
         undertaken by NGC in a manner consistent with the principles and
         methodologies set out in the document entitled "Methodology Document
         for the Recalculation of Zonal Weighting Factors" published by NGC for
         this purpose. Such recalculated figures for ZWFlead and ZWFlag ("the
         Final Zonal Weighting Factors"), together with the Total Actual
         Capability, shall be published by NGC in the Seven Year Statement. Each
         Final Zonal Weighting Factor (both leading and lagging) shall not in
         any event be greater than 3.000 and (for the avoidance of doubt) no
         determination of ZWFlead, ZWFlag, and TAN shall be made in respect of
         any such twelve month period when Y=0.

         NGC shall derive the Total Actual Capability from the Mvar capability
         (required under and in accordance with the Connection Conditions of the
         Grid Code) of Generating Units
         in respect of which Ancillary Services Agreements have been or will be
         amended or concluded to give effect to the provisions of sub-paragraphs
         42 and 4.3 of this Schedule. In respect of any twelve month period
         ending 31st March. such Mvar capability shall be reduced pro rata for
         all Settlement Periods in such twelve month period in respect of which
         no capability payments referred to in this Appendix I shall fall due:-

                    (a)  by virtue of  paragraph 7 below  (with  effect from the
                         commencement  of the twelve month period in  question);
                         and

                    (b)  by virtue of  paragraph  8 below  (until the end of the
                         twelve month period in question): and

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

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

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

         with

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

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

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

5.       Indexation

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

                  I        =                         RPI2
                                                     RPI1,
         Where

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

         RPI1 is the RPI for March, 1994 (142.5).

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

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

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

6.       Information Unavailable

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

7.       Commissioning

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

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

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

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

8.       De-energisation, Decommissioning and Disconnection

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

9.       Reconciliation

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

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

         with

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

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

6.       Testing

         NGC reserves the right to require to be included in any Market
         Agreement, on a basis to be agreed with a Tenderer, terms with regard
         to the carrying out of a Contract Test. The provisions of Grid Code OC
         5.5.1 relating to the carrying out of a Reactive Test (including
         re-tests) shall apply to the carrying out of Contract Tests.

7.       Termination

         Save where expressly provided otherwise in a Tender, each Market
         Agreement shall contain terms entitling NGC to terminate that Market
         Agreement in the event that the User fails to provide a satisfactory
         level of service and entitling the User to terminate the Market
         Agreement in the event that NGC fails (without reasonable cause) to
         make due payment to the User, in each case as more particularly defined
         therein.

8.       De-energisation, Decommissioning and Disconnection

         Subject to all rights and obligations of NGC and the User accrued at
         such date, utilisation, available capability and synchronised
         capability payments referred to in this Appendix 2 shall cease to fall
         due and payable to any User in respect of any Despatch Unit with effect
         from the date of expiry or termination for whatever reason of the
         relevant Market Agreement in accordance with its terms or (if earlier)
         with effect from the date of De-energisation, Decommissioning or
         Disconnection of that Despatch Unit for any reason pursuant to the
         relevant Supplemental Agreement or this Agreement.

1.       Pooling and Settlement Agreement

         For the avoidance of doubt, nothing in this Appendix shall affect the
         rights and obligations of those Parties also party to the Pooling and
         Settlement Agreement under Clause 60 and Schedule 21 thereto with
         regard to Metering Equipment and Metering Systems insofar as such
         provisions relate to Reactive Energy.

2.       Despatch Units

2.1      For the purposes of this Schedule and the Appendices, subject always to
         sub-paragraph 2.2. the quantities of Mvarh imported and exported by a
         Despatch Unit shall be derived from the relevant Metering System for
         that Despatch Unit registered with the Settlement System Administrator.

2.2      Where the existing Metering System for the Despatch Unit registered
         with the Settlement System Administrator does not incorporate Metering
         Equipment capable of measuring and recording Mvarh imports and exports
         for that Despatch Unit for each Settlement Period. then the relevant
         User shall register or procure that there is registered in accordance
         with Clause 60.2.2 of the Pooling and Settlement Agreement a Metering
         System which does incorporate such Metering Equipment.

                  2.4.1 Mvarh import and export values for the Despatch Unit are
                  not measured at the Commercial Boundary, and/or

                  2.4.2 Mvarh import and export values for the Despatch Unit are
                  measured by more than one Meter; and/or

                  2.4.3 the Mvarh import and export values for the Despatch Unit
                  are measured by a Meter which also measures the Mvarh import
                  and export values of one or more other Generating Units. Plant
                  and Apparatus or other equipment,

     then appropriate loss adjustment factors and aggregation  methodologies (as
     the case may be)  shall be used to  determineon  a  Settlement  Period
     basis the Mvarh  import  value and Mvarh export value for the relevant
     Despatch Unit at the  Commercial  Boundary to be used for the purposes
     of this Schedule.

         Subject always to sub-paragraph 2.5, the appropriate factors and
         methodologies for each relevant Despatch Unit shall be agreed by NGC
         and each relevant User (both acting reasonably) in the relevant
         Ancillary Services Agreement by adoption of one or more of the factors
         or methodologies set out in the document entitled "Methodology Document
         for the Aggregation of Reactive Power Metering" (as amended from time
         to time) published by NGC for this purpose. This document shall specify
         the respective factors and methodologies to be applied for particular
         Metering System configurations in order to determine so far as
         reasonably practicable the Mvarh import value and Mvarh export value
         for the relevant Despatch Unit at the Commercial Boundary as required
         by this sub-paragraph 2.4

2.5      Loss adjustment factors and aggregation methodologies need not be
         agreed between NGC and the relevant User in connection with any
         configuration described in sub-paragraph 2.4.3 in respect of periods
         prior to 1st April, 1998.

(or other equipment)

         In respect of each Generating Unit whose MW output is sold in
         accordance with the Pool Rules, the provisions of paragraph 2 shall
         apply (as if references therein to Despatch Unit were to Generating
         Unit). In all other cases, the following provisions shall apply:-

3.1      The quantities of Mvarh imported and exported shall be measured and
         recorded through Meters complying with all relevant Codes of Practice
         to the extent applying to Reactive Energy, Which shall include without
         limitation those relating to calibration, testing and commissioning.

3.2      Such Meters shall be capable of providing a Mvarh import and export
         value for each Settlement Period for each Non Centrally Despatched
         Generating Unit or other Plant and/or Apparatus or other equipment.

3.3      Such Meters shall be situated as close as reasonably practicable to the
         Commercial Boundary taking into account relevant financial
         considerations.

                                   Appendix 5
                              Submission of Tenders


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

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

1.       Reactive Power Capability

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

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

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

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

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

                                   Appendix 8
                               Charging Principles


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

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

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

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

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

3.       Further for the avoidance of doubt, the totality of payments referred
         to in paragraph I above shall, to the extent affecting the specific
         costs therein identified, take due account of any change in or
         amendments to, or replacement of, the Pooling and Settlement Agreement,
         the Grid Code and any other statutory or regulatory obligation, in each
         case coming into force or effect after 1st October, 997 and affecting
         the provision of the Obligatory Reactive Power Service.

     for the purpose of procuring Standard Connection Agreements in
     accordance with Clause 3.2 and 3.5 and shall procure that the Relevant

          3.1.2not make or give any representation or warranty in relation to

          on each occasion on which it or any Relevant  Exempt  Supplier  enters
          into a Supply  Contract  (whether  written  or oral)  (except  for the
          renewal of an existing Supply  Contract  entered into after [31 August
          1998]) that unless and to the extent that the provisions of Clause 3.5
          apply to the relevant Customer:

                                       18

<PAGE>


3.2.1     there is included in that Supply Contract the term set out in
          Schedule 2 or another term having the same effect as that term
          and that such term is drawn to the attention of the relevant
          Customer before the Supply Contract is entered into; and

    costs, demands, claims, expenses,
    liability, loss or damage arising from, or incurred by the Company as a

    case that a Standard Connection Agreement was procured in accordance
    with Clause 3.2 or Clause 3.5 (where the User has procured a Standard

connection. Where non-standard terms are agreed, the Company shall notify the
User as soon as reasonably practicable of any non-standard terms which affect

3.5 Notwithstanding the provisions of Clause 3.2, when at any time prior to 31st
    March 2000 the User or any Relevant Exempt Supplier proposes to enter into
    or enters into a Supply Contract with any Customer who:

    3.5.1  is being supplied with electricity other than as a Tariff
           Customer of the Company before [31st August 1998]; and

    3.5.2  as a relevant demand in Megawatts calculated in accordance with

           or entered into between the User or any Relevant Exempt Supplier and
           the relevant Customer.
        
      then by way of exception from the provisions of Clause 3.2 and in
      respect of the Exit Points referred to in Clause 3.5.3 and any Exit

             written notice, De-energise any Metering Point if:

             10.7.1  the Company  is  entitled  to  do  so  pursuant  to  the
                     Connection Agreement relating to such Metering Point; or

            10.7.2   any of the conditions set out in Clause  4.2 cease to be
                     fulfilled (or, in the case of Clause 4.2.4,  remain
                     unfulfilled 10 Working Days after the service of notice by
                     the Company requiring the User to remedy the  situation) in
                     relation to the relevant Exit Point (or, in the case of an
                     Unmetered Supply, any one or more of the relevant Exit
                     Points).


10.8         Notwithstanding the provisions of Clause 10.7
             the Company may, at any time with no prior notice to the User,
             De-energise any Metering Point if:

             10.8.1  the Company is  instructed,  pursuant to the terms of the
                     Master Connection and Use of System Agreement (as amended
                     from time to time) or the Settlement Agreement (as amended
                     from time to time), to do so;

            10.8.2   the Company reasonably considers it necessary to do so for
                     safety or system security reasons;

            10.8.3   the Company reasonably considers it necessary to do so to
                     avoid interference with the regularity or efficiency of its
                     Distribution System;

            10.8.4   an accident or emergency occurs or threatens  to occur
                     which requires the Company to do so to avoid the risk of
                     personal injury to any person or  physical  damage to the
                     property of the Company, its officers, employees or agents
                     or the property of any other person;

            10.8.5   it is entitled to do so under Schedule 11; or

            10.8.6   subject  to the terms of a replacement agreement,  this
                     Agreement is terminated in accordance with the provisions
                     of  Clause 18.

            In these circumstances the Company shall
            inform the User as soon as reasonably  practicable and in
            any event by the end of the next Working Day when MPAS is
            available of the fact that the Metering Point has been
            De-energised.

10.9         If the Company resolves to De-energise a Metering Point pursuant
             to Clause 10.7 or 10.8 then:

             10.9.1  the Company shall decide on the extent and nature of the
                     De-energisation Works required to De-energise the relevant
                     Metering Point; and

            10.9.2   the Company shall Re-energise the Metering Point as soon
                     as reasonably practicable after the circumstance giving 
                     rise to such De-energisation has ended;

            10.9.3   except where  the  Company  resolves  to  De-energise  a
                     Metering Point pursuant to Clauses 10.7.1, 10.8.1, 10.8.2,

                     10.8.3,  10.8.4  or  10.8.6 following termination of this
                     Agreement  by the User under  Clause 18.4 the Company
                     shall undertake both the De-energisation  Works and the
                     subsequent  Re-energisation  Works  at the cost of the
                     User and the User shall pay the  Company,  the relevant
                     charges  listed at Schedule 4 associated  with both the
                     De-energisation  Works and the subsequent
                     Re-energisation  Works. 


10.10       If the Company De-energises a Metering Point pursuant to Clause
            10.7 or 10.8 and such Metering Point remains De-energised for a
            period of 3 Working Days then:

             10.10.1 the Company shall forthwith instruct the User to send a
                     Registration Notice to the MPAS Operator instructing the
                     MPAS Operator to register the relevant Metering Point as
                     de-energised (but only, in the case of an Unmetered 
                     Supply, if the De-energisation works have ceased the flow
                     of electricity through each relevant Exit Point); and

            10.10.2  within 2 Working Days of receiving  an instruction  from
                     the Company pursuant to Clause 10.10.1, the User shall send
                     such a Registration Notice to the MPAS Operator.

10.11        If the Company Re-energises a Metering Point pursuant to Clause
             10.9 then:

             10.11.1 if an  instruction  has been given by the  Company  under
                     Clause 10.10.1 the Company shall forthwith instruct the
                     User to send a Registration Notice to the MPAS  Operator
                     instructing the MPAS Operator to register the  relevant
                     Metering Point as energised (but only, in the case of an
                     Unmetered Supply, if the Re-energisation works have allowed
                     the flow of electricity through each relevant Exit Point);
                     and

             10.11.2 within 2 Working Days of receiving  an  instruction  from
                     the Company pursuant to Clause 10.11.1,  the User shall
                     send such a Registration Notice to the MPAS Operator.


10.12        The User shall not be  entitled  to  Re-energise  a Metering
             Point which has previously been  De-energised by the Company
             on its own behalf (for the avoidance of doubt, not acting on
             the instructions or at the request of the User) or on behalf
             of the Company.  For the avoidance of doubt,  the User shall
             be  entitled  to  Re-energise  a  Metering  Point  which has
             previously  been  De-energised  by or on behalf  of  another
             supplier.

10.13If      there  is no  reasonably  foreseeable  future  use for a
             Metering  Point the User  shall be  entitled  to send to the
             Company  a   Disconnection   Notice.   In   respect  of  any
             Disconnection  Notice sent to the  Company  pursuant to this
             Clause, the User shall:


             10.13.1 warrant  that to the best of its  knowledge  and  belief,
                    having exercised Good Industry Practice, the Metering Point
                    has been  De-energised  and  that  there is no reasonably
                    foreseeable future use for the Metering Point giving details
                    of any De-energisation  Works which it has undertaken and
                    providing an explanation for why there is no reasonably
                    foreseeable future use for the Metering Point; and

             10.13.2 indemnify  the Company  against all costs,  demands,
                     claims, expenses,  liability, loss, or damage which the
                     Company  incurs in consequence of acting in reliance on
                     the warranty given in Clause 10.13.1 which proves to be
                     in any way inaccurate or misleading.

10.14        If a  third  party  contacts  the  Company  to  request
             directly  or  indirectly  that the  Company  undertakes
             works in relation to a Metering  Point because there is
             no reasonably  foreseeable future use for that Metering
             Point and the Company is satisfied that the third party
             is entitled to make such request then the Company shall
             contact  the  relevant  User and request it to submit a
             Disconnection Notice. Upon receiving such a request the
             User shall send the Company the requested Disconnection
             Notice unless in the User's reasonable opinion there is
             a  reasonably  foreseeable  future use for the Metering
             Point.

10.15        If, in any case, in the  reasonable  opinion of the Company there
             is a reasonably  foreseeable  future use for the  Metering  Point
             then  the  Company   shall  not  be  obliged  to  comply  with  a
             Disconnection  Notice  received  under  Clause 10.13 or 10.14 and
             where the Company decides not to comply it shall provide the User
             with the reasons for its decision.

             reasonably  foreseeable  future use for a Metering Point then the
             Company shall contact the relevant User and request it to submit
             a Disconnection  Notice.  Upon receiving such a request the User
             shall send the Company the requested  Disconnection Notice unless
             in the User's reasonable   opinion   there  is  a  reasonably
             foreseeable future use for the Metering Point.

10.17        For the avoidance of doubt, the warranty and indemnity  contained
             in  Clause  10.13  shall not  apply to any  Disconnection  Notice
             requested by the Company pursuant to Clause 10.14 and 10.16.

10.18        Subject to Clause 10.15, within 5 Working Days of receipt of the
             Disconnection  Notice, the Company shall send a Registration
             Notice to the MPAS Operator  instructing  it to register the
             Metering  Point as de-registered.


10.19        If a Metering Point has been De-energised by or on behalf  of a
             previous supplier and the Company receives a request from the User
             to Re-energise such Metering Point then:


             10.19.1 the Company shall  Re-energise the Metering Point as soon
                     as reasonably practicable and notify the User of when it
                     expects to carry out the Re-Energisation Works;

            10.19.2  the Company shall carry out all necessary Re-energisation
                     Works at its own cost and shall then reclaim such costs 
                     from the previous supplier; and


             10.19.3 the  Company shall notify the  User  as soon  as the
                     Re-energisation Works are complete and the User shall,
                     within 2 Working Days of receiving such notification, send
                     a Registration Notice to the MPAS Operator instructing the
                     MPAS  Operator to register the relevant Metering Point as
                     energised.


10.20        The Company shall notify Customers of and carry out System Outages

             doubt, when at any time the User ceases to be permitted to supply
             electricity  on the basis  that the supply of  electricity  is an
             Unmetered Supply,  the User shall immediately become bound by all
             the  provisions of this Clause 12 (other than those relating only
             to an Unmetered Supply).



13.          PROVISION OF INFORMATION

     after 31 August 1998, as soon as reasonably practicable following

         information to the Company in respect of any Exit Point through which
         the relevant supply is to be delivered:

          13.2.1 the  contact name for the Customer if different from the
               Customer's name; and

          13.2.2 the  Customer's  postal  address if different from the Metering
               Point Address.


13.3      The User shall use reasonable endeavours to notify
          the  Company of any changes to the details set out in Clause 13.1

13.4      Where  the  User or its  agent  or any  Relevant  Exempt  Supplier
          receives a report or enquiry  from any person about any matter or
          incident that does or is likely to:

          13.4.1 cause danger or require urgent  attention in relation
                 to the supply or  distribution  of  electricity  in the
                 Company's  authorised  area  (as  defined  in  the  PES
                  Licence) through the Distribution System; or

         13.4.2  affect  the maintenance of the security, availability  and
                quality  of service of the Distribution  System, the User shall
               notify the Company of such report or enquiry in a prompt and
               appropriate manner having regard to the nature of the incident to
               which the report  relates.  The User shall notify the Company by
               telephone or post using the telephone number and postal address
               identified  in the Security and Safety of Supplies  Statement or
               such other telephone number as may from time to time be notified
               in writing by the Company. For the avoidance of doubt,  if the
               User does not discharge its obligation  under Condition 15 of the
               Second Tier Supply Licence by providing to customers the address
               and telephone number of the Company's enquiry service established
               pursuant  to Condition 9A of the PES  Licence,  the User  shall
               notify  the Company of reports received from customers in
               accordance with this Clause 13.4.

13.5           The User shall, with the consent of any Customer who may be
               expected,  by virtue of being of pensionable age or disabled or
               chronically sick, to require advance notice of interruptions to
               the supply of electricity, provide the Company with appropriate
               details  concerning that Customer and his requirement within 3
               Working  Days of receiving such requirements pursuant to its
               obligations under Condition 30 of the Second Tier Supply Licence.

13.6      The User shall, with the consent of any Customer who has agreed a
          password with the User or any Relevant Exempt Supplier for access to

          concerning that Customer and his password within 2 Working Days of
          notification of such password by the Customer.

13.7     The User shall use reasonable endeavours to ensure that all the facts,
         information and other details provided pursuant to Clause 13.5 and 13.6

         and complete in all respects.

14.      DEMAND CONTROL

14.1     The parties undertake to comply with Schedule 11.

15.      REVENUE PROTECTION

15.1     The Company shall provide a revenue protection service in accordance
         with the provisions of the Revenue Protection Code of Practice.

15.2     The User shall comply with its obligations under the Revenue Protection
         Code of Practice.

16.      GUARANTEED PERFORMANCE STANDARDS

16.1     To the extent that, due to an act or omission on the part of the
         Distribution Business of the Company, compensation pursuant to the ESPR
         would be payable to the Customer by the Company if such Customer were a
         Tariff Customer of the Company then the Company shall make an
         equivalent compensation payment to the User for the benefit of the
         Customer in accordance with the provisions of this Clause 16.

16.2 To the extent that, due to circumstances other than those described in
Clause 16.1, compensation pursuant to the ESPR would be payable to the Customer
by the Company if such Customer were a Tariff Customer of the Company then the
Company shall not be liable to make any payment to the User for the benefit of
the Customer.

16.3 In the circumstances described in Clause 16.1, the Company
will comply with the terms and procedures of the ESPR as if the Customer were a
Tariff Customer provided that:



     16.3.1 the User shall be deemed to be a "person having  apparent  authority
          to represent the customer" for the purposes of ESPR regulation 2(4)(d)
          if the  Customer  independently  contacts  the User in  relation  to a
          matter which forms the basis of the  Customer's  claim under the ESPR;
          and

   16.3.2 where the ESPR  require  the  Company  to "pay to the  customer  the
          Prescribed  Sum" the Company shall pay the User the Prescribed Sum for
          the benefit of the  Customer and the User shall pass the payment on to
          the Customer as soon as reasonably  practicable  by [method of payment
          ].

16.4   If the  Customer  contacts the User in relation to a matter which might
       form  the  basis  of a claim  under  the  ESPR  then  the  User  shall
       diligently  record the details of the  Customer's  complaint and shall
       not agree or imply that the  Customer's  complaint is valid unless the


                                       36

<PAGE>

       matter is one which would be governed by Clause 16.2. If the matter is
       one which in the User's reasonable  opinion will be governed by Clause
       16.1  then  the  User  shall  pass on the  details  of the  Customer's
       complaint to the Company as soon as  reasonably  practicable  together
       with details of the Customer's name and address. In such circumstances
       the Prescribed Period will relate to the time at which the Customer or
       the User on behalf of the  Customer  contacts the Company and the time
       at which the  Customer  contacts  the User will not be relevant to the
       calculation of the Prescribed Period.

16.5 If the Customer contacts the Company in relation to a matter which might
form the basis of a claim under the ESPR then the Company shall diligently
record the details of the Customer's complaint and shall not agree or imply that
the Customer's complaint is valid unless the matter is one which would be
governed by Clause 16.1. If the matter is one which in the Company's reasonable
opinion will be governed by Clause 16.2 then the Company shall tell the Customer
to contact the User direct. In such circumstances the Prescribed Period will
relate to the time at which the Customer contacts the User and the time at which
the Customer contacts the Company will not be relevant to the calculation of the
Prescribed Period.

 16.6 When the User has received a payment from the Company
pursuant to Clause 16.3.2 then the User shall pass such payment to the Customer
as soon as reasonably practicable and if, due to the User's delay, an additional
payment becomes due pursuant to ESPR regulation 14 then this additional payment
shall be the liability of the User.


16.7 Neither party shall lead a Customer to
believe that he has a valid claim for a guaranteed standard payment by reason of
the action or default of the other party. Where however a Customer does have a
valid claim, a breach of the provisions of this Clause 16.7 shall not excuse the
party against whom the claim lies from making the relevant payment.


16.8 In the event of a dispute between the Company and the User as to which
     party is liable to pay  compensation  pursuant  to Clause 16.1 or 16.2
     then in the first  instance  the Company  shall make the  compensation
     payment for the benefit of the Customer and then the dispute  shall be
     referred to the Director and shall be deemed to be a dispute which may
     be referred to the Director by either party in accordance with section
     39 of the Act and ESPR regulation 13. The rules on  "Presumptions  and
     evidence"  contained  in ESPR  regulation  16 and all  other  relevant
     provisions  of the ESPR shall be deemed to apply to any such  dispute.
     The Company shall, as soon as reasonably  practicable after the end of
     each  Quarter,  provide  the User  with a report  in  accordance  with
     Schedule 13.

17.VARIATIONS

17.1The parties acknowledge and agree the desirability of achieving and
     maintaining consistency and the absence of conflict between the
     provisions of this Agreement and each of the Relevant Instruments.
     However, the parties recognise that, due principally to the different
     functions and objectives of this Agreement and of the Relevant
     Instruments, the fact that not every Relevant Instrument binds both the
     Company and the User, and the different procedures for the variation of
     this Agreement and of the Relevant Instruments, it will not in all
     circumstances be possible to avoid inconsistency or conflict.
                                       37

<PAGE>


17.2 The parties acknowledge that the Settlement Agreement may be amended from
time to time in a manner which is likely to change the User's requirements for
the provision of Use of Distribution System. Whenever such a change occurs the
User may serve upon the Company a notice setting out the change to the
Settlement Agreement and the consequent amendments to the Agreement which it
believes are required. Upon receipt of such notice by the Company, the parties
shall negotiate in good faith the terms of any amendments. If amendments to the
Agreement have not been agreed and put into place within 14 days after the User
serves its notice proposing changes, either party shall be entitled to refer the
matter to the Director, pursuant to Condition 11F of the PES Licence. 

17.3 The  Company  may  propose amendments to this Agreement to the extent
     necessary to ensure that any change to, or the coming  into force of, any
     Relevant Instrument does not materially affect the Company's ability to
     perform, or the cost to it of performing, any of its obligations under this
     Agreement.  Any such proposal shall be in writing and shall specify:

     17.3.1  the Relevant Instrument concerned;

     17.3.2 where relevant, the nature of the change to such Relevant Instrument
            relied on by the Company;

     17.3.3 the proposed amendments to the Agreement;

     17.3.4 the reasons why the Company considers the proposed amendments to be
            within the scope of this Clause 17.3;


     17.3.5 that similar amendments shall be proposed by the Company in respect
          of  ach subsisting agreement which it has entered into in its
          Authorised Area for the provision  of Use of Distribution System
          services and which is similarly affected; and

   17.3.6 that, so far as the Company is reasonably able, taking account of
          all  relevant factors,  the amendments will result in the  lowest
          practicable increase  in  the charges  payable for the  Use  of
          Distribution  System  services having  regard  to the other  options
          available.

17.4  Unless the User serves a counter-notice  within 28 days of
      receipt of such  proposal,  such  proposed  amendment to the Agreement
      shall take  effect  upon the expiry of such 28 day  period.  Where the
      User serves a  counter-notice,  both parties  shall  negotiate in good
      faith  the  terms of any such  variation,  but if a  variation  to the
      Agreement has not been agreed and put into effect within 28 days after
      it has been proposed by the Company, either party shall be entitled to
      refer the matter to the  Director  pursuant to Condition 8D of the PES
      Licence.

17.5  For the avoidance of doubt, nothing in this Agreement shall oblige either
      party to act at any time in a manner contrary to any existing, new or
      changed Relevant Instrument.

17.6 Without prejudice to Clause 17.2 and 17.3,  either party shall at any
     time be entitled to propose  amendments to this Agreement by notice in
     writing to the other party.  The parties shall negotiate in good faith
     the terms of any such variation,  but if a variation to this Agreement
     has not been  agreed and put into  effect  within 28 days after it has
     been  proposed,  either party shall be entitled to refer the matter to
     the Director, pursuant to Condition 8D of the PES Licence.

17.7 The parties  shall give effect to any determination  made by the  Director
     pursuant to Condition 8D of the PES Licence in relation to this  Agreement.
     If the Director  determines that amendments to the Agreement are required,
     the Company shall make such amendments as have been specified by him. 17.8
     Except where this Agreement provides to the contrary, no amendment to this
     Agreement  shall be  effectiv  unless in writing  signed by both  parties.

18.2 The  Company  may  terminate  this  Agreement  by giving the User 3 months'

          Party or the appointment of a receiver or an  administrative  receiver

               by a circumstance of Force Majeure; or

          (B)  (for the avoidance of doubt) such cessation  involves  solely the

 19.     FORCE MAJEURE

 19.1    If either party (the "Affected Party") shall be unable to carry out any
         of its  obligations  under this Agreement due to any circumstance  of
         Force  Majeure  this  Agreement  shall  remain in  effect  but save as
         otherwise  provided in this Agreement both parties' obligations shall
         be suspended  without liability for the period during which the
         circumstance of Force Majeure prevails provided that:

        19.1.1  the  Affected  Party  gives  the  other  party prompt  notice
                describing  the  circumstance of Force  Majeure, including the
                nature of the occurrence  and its expected  duration and, where

               the Affected Party uses all  reasonable  efforts to mitigate the
               impact of the circumstances  of Force  Majeure and to remedy its
               inability to perform  as  quickly  as  possible;  and  19.1.5
               immediately after the end of the circumstances of Force Majeure
               the  Affected Party  notifies  the other party in writing of the

             confidential  nature,

     and to the extent  that any  Affiliate  or
     Related  Undertaking of the User is in possession of Confidential
     Information the User shall procure that such Affiliate or Related

      confidentiality  of, and not directly or  indirectly  reveal,  report,
      publish,   disclose  or   transfer  or  use  for  its  own   purposes,

               does   apply  and   thereafter   ceases  to  be  subject  to  the
               restrictions imposed by this Clause 21; or

          (C)  (after it is furnished to the User) enters the public domain;

               otherwise (in any such case) than as a result of (i) a breach
               by the User of its obligations in this Clause 21 or (ii) a
               breach by the person who disclosed that Confidential
               Information of that person's confidentiality obligation and
               the User is aware of such breach;

21.3.3 if the User is required or permitted to make disclosure of the
Confidential Information to any person:

               (B)  in compliance with the provisions of  any Relevant
                    Instrument;

               (C)  in  compliance  with any  other  law or  regulation;  (D) in

               (E)  pursuant  to  the  rules  of  the  Electricity   Arbitration
                    Association or pursuant to any judicial or arbitral  process
                    or  tribunal  of  competent  jurisdiction; 

     21.3.4 to  any  Affiliate or  Related  Undertaking of the  User,  to the
          employees, directors, agents, consultants and professional advisers of
          the User or any Affiliate or Related  Undertaking  of the User, and to
          any Relevant Exempt Supplier in each case on the basis set out in
          Clause 21.4; or

     21.3.5 to  the  extent  the  Confidential  Information  is  required  to be
          disclosed  by  the  User  for  the   purposes  of  providing   billing
          information to Customers.

21.4 The User shall take all reasonable  steps to ensure that any such person as
     is referred  to in Clause  21.3.4 to whom the User  discloses  confidential
     information  does not use that  confidential  information  for any  purpose
     other  than  that for  which it is  provided  and  does not  disclose  that
     confidential information otherwise than in accordance with this Clause 21.

the term of this Agreement effect and maintain, all such registrations as it is
required to effect and maintain under the Data Protection Act to enable it
lawfully to perform the obligations imposed on it by this Agreement. The User
undertakes to comply with the Data Protection Act in the performance of this
Agreement.

 21.6 The User undertakes that, in any case where information to be
disclosed under this Agreement may lawfully be disclosed only with the prior
consent of the person to whom the information relates, it will use its

22. DISPUTES

22.1Save where expressly stated in this Agreement to the contrary, and subject
    to any contrary provisions of the Act, any licence issued pursuant to
    the Act or the Regulations (or any other regulations made under Section
    29 of the Act), or the rights, powers, duties and obligations of the
    Director or the Secretary of State under the Act, any such licence or
    otherwise howsoever, any dispute or difference of whatever nature
    howsoever arising under out of or in connection with this Agreement
    between the 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.

22.2 Whatever the nationality, residence, or domicile of either 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 or 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.


 22.3 Subject always to Clause 22.5, if any
consumer of electricity (the "consumer") brings any legal proceedings in any
court against any party (the "defendant party") and the defendant party wishes
to make a third party claim (as defined in Clause 22.4) against the other party
which would but for this Clause 22.3 have been a dispute or difference referred
to arbitration by virtue of Clause 22.1 then, notwithstanding the provisions of
Clause 22.1 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 consumer and the defendant party but also between either or both of
them and the other party whether by way of third party proceedings or otherwise
as may be ordered by the court.


 22.4 For the purpose of this Clause 22 "third party claim" shall mean:


     22.4.1 any claim by a defendant  party against the other party  (whether or
          not already a party to the legal  proceedings) for any contribution or
          indemnity; or

                                       45

<PAGE>


     22.4.2 any claim by a  defendant  party  against  the  other  party for any
          relief or remedy  relating to or connected  with the subject matter of
          the legal  proceedings  and  substantially  the same as some relief or
          remedy  claimed  by the  consumer;  or

     22.4.3 any  requirement  by a  defendant  party that any  question or issue
          relating  to or  connected  with  the  subject  matter  of  the  legal
          proceedings  should be determined not only as between the consumer and
          the defendant party but also as between either or both of them and the
          other party (whether or not already a party to the legal proceedings).



22.5   Clause 22.3 shall apply only if at the time the legal proceedings are
       commenced no  arbitration  has been  commenced  between the defendant
       party  and  the  other  party  raising  or involving  the same  or
       substantially the same issues as would be raised by or involved in the
       third party  claim.  The  tribunal in any  arbitration which has been
       commenced  prior  to  the  commencement of  legal proceedings  shall
       determine  the question,  in the event of dispute,  whether the issues
       raised or involved are the same or substantially the same.

23.  RESTRICTIVE TRADE PRACTICES ACT

     of which it forms part constitutes a restriction or information
     provision within the meaning of the Restrictive Trade Practices Act
     1976 (the "RTPA") so as to render this Agreement or arrangement (as the
     case may be) registrable under the RTPA, no such restriction or
     information provision shall take effect until the earlier of:

     23.1.1 the day after particulars of this Agreement or that arrangement have
          been  furnished to the Director  General of Fair Trading in accordance
          with the RTPA; or

     23.1.2 the day after the  Secretary  of State  for Trade and  Industry  has
          granted an exemption  pursuant to Section 100 of the Act in respect of
          this Agreement or that arrangement. MISCELLANEOUS

24.1  Entire Agreement

     24.1.1 This  Agreement and any document  referred to herein  represents the
          entire understanding, and constitutes the whole agreement, in relation
          to its subject matter and supersedes  any previous  agreement  between
          the  parties  with  respect  thereto  and  without  prejudice  to  the
          generality of the foregoing excludes any warranty,  condition or other
          undertaking implied at law or by custom.

     24.1.2 Each party confirms  that,  except as provided in this Agreement and
          without  prejudice to any liability for fraudulent  misrepresentation,
          no party has relied on any  representation,  warranty  or  undertaking
          which is not contained in this  Agreement or any document  referred to
          herein.

24.2     Severability

         If any provision of this Agreement shall be held to be invalid or
         unenforceable by a judgement or decision of any court of competent
        
                                       46
<PAGE>

         jurisdiction or any authority (including the Director) whose decisions
         shall be binding on the parties, the same shall be deemed severable and
         the remainder of this Agreement shall remain valid and enforceable to
         the fullest extent permitted by law. 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 or unenforceable provision in
         order to give effect, so far as practicable, to the spirit of this
         Agreement.

24.3     Waivers

         The failure by any party to exercise, or the delay by any party in
         exercising any right, power, privilege or remedy provided under this
         Agreement or the Distribution Code or by law shall not constitute a
         waiver thereof nor any other right, power, privilege or remedy. No
         single or partial exercise of any such right, power, privilege or
         remedy shall preclude any future exercise thereof or the exercise of
         any other right, power, privilege or remedy.

24.4     Data Transfer

         24.4.1 Any notice, request or other communication shall be sent by the
         means  (if any)  indicated  in  Schedule  10 and  shall  have the
         content (if any)  indicated in Schedule 10 and where  Schedule 10
         specifies a Data Transfer Catalogue  reference number in relation
         to any  notice,  request  or other  communication,  such  notice,
         request or communication shall be sent in the format and with the
         content  described  under  such  reference  in the Data  Transfer
         Catalogue, as amended from time to time.

         24.4.2 Where this  Agreement  requires  any  notice,  request or other
         communication  to be sent  via the  Data  Transfer  Network,  the
         relevant  message  shall be addressed to the  appropriate  Market
         Domain I.D. as follows:

               (A)  if to the Company, [insert appropriate M.D.I.D];

               (B)  if to the User, [insert appropriate M.D.I.D].

         24.4.3 Where this  Agreement requires  any  notice,  request or other
               communication to be sent via the Data Transfer Network, the party
               sending the relevant  message shall be responsible for ensuring
               that it reaches the relevant Gateway within any time period laid
               down in this Agreement for the provision of such notice, request
               or  communication (and any such message shall be deemed received
               by the  recipient  at the point in time it is  delivered to such
               Gateway). Provided that the party sending a message shall have no
               obligation  to ensure  receipt where the intended  recipient has
               failed,  contrary  to the Data Transfer Service  Agreement,  to
               remove or process all messages delivered  to its Gateway and to
               ensure that such  messages  are made  available  to its internal
               systems as  expeditiously as possible so that the Gateway is able
               to continue to process incoming and outgoing messages.

         24.4.4 If the  Data  Transfer  Network  or any  relevant  part of such
               network is at any time for any reason unavailable for the sending
               of  messages  between  the  parties,  then during the period of
               unavailability:
                                       47

<PAGE>


               (A)  the  parties  shall use  any means  reasonable  in  the
                    circumstances  to  send  any   notice,  request  or  other
                    communication that this Agreement would otherwise require to
                    be sent via the Data Transfer Network;

               (B)  where  other  means  are  used  in  accordance  with  Clause
                    24.4.4(A),  the parties  shall be relieved  from any service
                    levels set out in this  Agreement  relating to any  affected
                    notice, request or other communication (except to the extent
                    that  this  Agreement  expressly  provides  for  alternative
                    service  levels in such  circumstances)  but shall use their
                    reasonable endeavours to send such notice,  request or other
                    communication as soon as reasonably practicable; and

               (C)  to the extent that no such other means are practicable given
                    the  nature  of  the   communication   and  the  surrounding
                    circumstances,  such  unavailability  of the  Data  Transfer
                    Network  shall be  deemed  (to the  extent  not  caused by a
                    breach  by  either  party  of  the  Data  Transfer   Service
                    Agreement) to constitute a circumstance of Force Majeure for

          the  recipient's  Gateway and such failure occurs for reasons  outside
          that  party's  direct  control,  the  breaching  party  shall  have no
          liability to the other under this  Agreement in respect of that breach
          and the parties  shall rely  instead upon the  provisions  of the Data

                  (ii)     it has provided and is not in default under the Cover
                           obligations referred to in paragraph 1.1.2 below;

                         agreed  between  the parties in such amount as shall be
                         notified by the Company to the User in accordance  with

         than 6 months which may be done in one of the following ways:

                  rating set out in the definition of Letter of Credit, provide
                  the Company with confirmation from the issuing bank that the
                  validity of the Letter of Credit has been extended for a
                  period of not less than 6 months on the same terms and

                  issuing bank with an Approved Credit Rating for an amount at

                  available for a period of not less than 6 months; or

                  continuing to have an Approved Credit Rating provide the
                  Company with confirmation from the issuing entity that the
                  validity of the Qualifying Guarantee has been extended for a
                  period of not less than 6 months on the same terms and
                  otherwise for such amount as is required by this Schedule 1;
                  or

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

        1.2.5     place such  amount in the  Escrow  Account  of an amount as
                  shall ensure that the credit balance  applicable to the User
                  and placed in the Escrow  Account shall be at least equal to
                  the  required  Amount.

      If the User fails at any time to  provide or  maintain
      Cover to the  satisfaction of the Company in accordance with
      the  provisions  of this  Schedule 1, the Company may at any
      time while such default  continues,  and if at such time any
      Letter of Credit and/or Qualifying Guarantee forming part of
      the  Cover  is  due  to  expire  within  nine  Working  Days
      immediately,  and without notice to the User, demand payment
      of the  entire  amount of any  outstanding  Letter of Credit
      and/or Qualifying  Guarantee and shall place the proceeds of
      the  Letter of Credit  and/or  Qualifying  Guarantee  to the
      Escrow Account.

1.4      Substitute Letter of Credit or Qualifying Guarantee

         1.4.1    If the bank issuing the User's Letter of Credit ceases to have
                  the credit rating set out in the definition of Letter of
                  Credit such User shall forthwith procure the issue of a
                  substitute Letter of Credit by a bank that has such a credit
                  rating or a Qualifying Guarantee or place cash in the Escrow
                  Account.

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

2.       Credit Monitoring

2.1      Determination of Cover

         The amount of Cover which the User shall be required to maintain shall
         be determined from time to time by the Company in accordance with this
         Schedule 1 on the basis of the criteria set out in paragraph 2.2, and
         shall be notified to the User.

2.2      Criteria for the provision of Cover

         If paragraph 1.1.2 applies, the amount of Cover required to be provided
         by the User is the greater of an amount to be reasonably assessed by
         the Company as the aggregate amount reasonably anticipated by the
         Company as being payable by the User in respect of Use of System
         Charges referred to in this Agreement over a 60 day period and
         (pound)1,000.

2.3      Six Monthly Variation

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

2.4      Increase or Decrease of Cover

         If, after considering any representation which may be made by the User,
         the Company reasonably determines that the User's Cover should be
         increased or decreased, it shall so notify the User. If the Company so
         determines that such Cover should be decreased and the User consents
         then that reduction shall take place. The Company shall consent to an
         appropriate reduction in the available amount of any outstanding
         Qualifying Guarantee or Letter of Credit and/or shall subject to
         paragraph 5.1 permit such part of the deposit held in the Escrow
         Account to be released to the User as is sufficient to reduce the
         User's Amount to the level of Cover applicable to it. If the Company so
         determines that the User's Cover should be increased, the User shall,
         within five Working Days of notice as aforesaid, procure an additional
         or replacement Qualifying Guarantee or Letter of Credit or place cash
         in the Escrow Account in an amount sufficient to increase its Amount so
         as to be at least equal to the new level of Cover applicable to it.

2.5      Notification in respect of Cover

         The Company shall notify the User promptly if:

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

         2.5.2    the Company shall make a demand under any such Qualifying
                  Guarantee or a call under a Letter of Credit; or

         2.5.3    the Company becomes aware that the User (a) shall cease to
                  have an Approved Credit Rating, or (b) shall be placed on
                  credit watch by the relevant credit rating agency (or becomes
                  subject to an equivalent procedure) which in any case casts
                  doubt on the User's retaining an Approved Credit Rating; or

                                       52
<PAGE>


         2.5.4    the Company becomes aware that any bank that has issued a
                  Letter of Credit which has not expired shall cease to have the
                  credit rating required by this Schedule 1; or

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

         Provided always that the failure by the Company to notify the User
         pursuant to this paragraph 2.5 shall not relieve the User of its
         obligations under and in accordance with the terms of this Schedule 1.

2.6      Release from Cover Obligations

         Upon the termination of this Agreement and provided that all amounts
         owed by the User in respect of the Use of System Charges and any
         other amount owed by the User under the Agreement have been duly
         and finally paid including  interest,  the User shall be released
         from the  obligation  to  maintain  Cover and the  Company  shall
         consent to the revocation of any outstanding Qualifying Guarantee
         or Letter of Credit and the User shall be  entitled  to  withdraw
         the balance (including interest credited thereto) standing to the
         credit of the User on the Escrow Account at that date. 

3.       Payment Default

         If, by 12:30 hours on any Payment Date the Company has been notified by
         the User or it otherwise has reason to believe that the User will not
         have remitted to it by close of banking business on the Payment Date
         all or any part ("the amount in default") of any amount which has been
         notified by the Company to the User as being payable by the User by way
         of the Use of System Charges on the relevant Payment Date or any other
         amounts owing under this Agreement except for the disputed amount of a
         Designated Dispute (as defined in Schedule 6), then the Company shall
         be entitled to act in accordance with the following provisions (or
         whichever of them shall apply) in the order in which they appear until
         the Company is satisfied that the User has discharged its obligations
         in respect of the Use of System Charges or such other amounts under
         this Agreement which are payable in respect of the relevant account:

         (a)      the Company, to the extent that the User is entitled to
                  receive payment from the Company pursuant to this Agreement
                  (unless it reasonably believes that such set-off shall be
                  unlawful), shall be entitled to set off the amount of such
                  entitlement against the amount in default;

         (b)      the amount of funds then standing to the credit of the Escrow
                  Account to the extent that it represents Cover provided by the
                  User in accordance with paragraph 1.2.2 shall be released to
                  the Company and set-off against the amounts unpaid by the User
                  and for that purpose the Company shall be entitled to place
                  such funds in any account of the Company at its sole
                  discretion and shall notify the User accordingly;

         (c)      the Company may demand payment under any outstanding Letter of
                  Credit supplied by the User in a sum not exceeding the amount
                  of the Cover;

                                       53
<PAGE>


         (d)      the Company may demand payment under any outstanding
                  Qualifying Guarantee provided for the benefit of the User
                  pursuant to paragraph 1.2.3.

4.       Utilisation of Funds

         In addition to the provisions of paragraph 3 above, if the Company
         serves a notice of termination under the terms of Clause 18 of the
         Agreement then the Company shall be entitled to demand payment of any
         of the Use of System Charges and any other amounts owing by the User
         under the Agreement which are outstanding whether or not the Payment
         Date in respect of them shall have passed and:

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

         (ii)     the funds in the Escrow Account to the extent that they
                  represent Cover provided by the User shall be released to the
                  Company and set-off against the Use of System Charges and any
                  other amount owing by the User under the Agreement unpaid by
                  the User and for that purpose the Company shall be entitled to
                  place any such amount released to it from the Escrow Account
                  to any account of the Company as it shall in its sole
                  discretion think fit.

5.       User's Right to Withdraw Funds
5.1      If the User is not in default in respect of any amount owed to the
         Company in respect of the Use of System Charges or any other amount
         owing by the User under the Agreement, the Company shall permit the
         release to such User within a reasonable time after such User's written
         request therefor any amount of cash provided by the User by way of
         Cover which exceeds the amount which such User is required to provide
         in accordance with paragraph 1 of this Schedule 1.

5.2      Interest (at a rate to be agreed by the User with the Bank) on the
         amount deposited in the Escrow Account shall accrue for the benefit of
         the User and be compounded quarterly.

6.       No Security

         effective to create a charge or other security interest.

7.       Disputes

         The parties shall attempt to resolve in good faith any dispute in
         relation to this Schedule 1. Where the dispute remains unresolved after
         14 days either party may refer the dispute to the Director for
         determination. Any determination by the Director shall be final and
         binding

Account:



Tn+1 = Tn x (In x 1/365) + Tn



where



Tn= amount due under a Reconciliation Account, including interest calculated on

          B.   the  parties  shall use  reasonable  endeavours  to  resolve  the

               Clause 22; and

          D.   following  resolution  of  the  dispute,  any  amount  agreed  or
               determined  to be payable  shall be paid  within 20 Working  Days
               after such agreement or  determination  and interest shall accrue
               on such  amount  plus Value Added Tax (if any) from the date such

     29.  PRINCIPLES

     29.1 Subject to the  provisions  of Clause 10 and this Schedule 7, the User
          shall  be  entitled  to  procure  the  performance  of  Works  on  the
          Distribution System by a person who is not an employee of the Company.
          For the  avoidance  of doubt  this  Schedule  7 does not apply to work
          carried  out by a  Meter  Operator  pursuant  to the  Meter  Operation
          Services Agreement.

     29.2 A Competent  Person  shall be  recognised  to be a suitable  person to
          carry out Works on the  Distribution  System in accordance with and to
          the extent specified in a Permission.

     29.3 Where the User  elects to have  Works  performed  on the  Distribution
          System by an Approved Contractor rather than the Company, the Approved
          Contractor  shall  undertake to perform all the categories of Works in
          accordance with and to the extent specified in the Permissions held by
          its  Competent  Persons,  and the  Company  shall  only be  obliged to
          undertake such  categories of Works as are not so specified.  The User
          shall  remunerate  the  Company  for  undertaking  any  such  Works by
          reference  to the  relevant  charges  set  out in  Schedule  4,  or by
          agreement where the charges for such Works are not set out therein.


     30.PROCEDURE FOR APPROVING CONTRACTORS

     30.1Where an Applicant has applied for approval as an Approved Contractor
          for the  purposes of this  Schedule 7, the  Company  shall appoint a
          
<PAGE>


          Quality Assurance Certification Body to carry out an assessment of the
          Applicant's qualifications for approved status. The Applicant shall be
          advised of any  assessment fees payable to the  Company.  The Quality
          Assurance Certification  Body shall  advise  the  Company and  the
          Applicant of the results of the  assessment,  and the  Company shall
          decide whether the Applicant may be approved together with the reasons
          for that decision.

     30.2 An approval pursuant to paragraph 3.1:


          30.2.1 shall be valid for three years, during which period the Company
               may  at  any  time  carry  out   inspections   of  the   Approved
               Contractor's work on site; and

          30.2.2 may be withdrawn at any time by the Company,  subject always to
               the Approved Contractor being given a reasoned  explanation.  The
               Company may accept an approval of an  Applicant  given by another
               public  electricity  supplier in  accordance  with the  procedure
               stated in this paragraph 3.

     31.PROCEDURE FOR RECOGNISING COMPETENT PERSONS

     31.1 A person shall be recognised by the Company as being a suitable person
          to perform Works on the Distribution System if that person is employed
          by an Approved  Contractor  and has been  appointed  in writing by the
          Approved  Contractor  as a  Competent  Person,  being  someone who has
          successfully   completed  satisfactory  training  and  examination  in
          electrical safety awareness and appropriate  technical knowledge,  and
          who  personally  holds  a  Certificate  of  Competence  issued  by the
          Approved  Contractor  as evidence of a suitable  qualification  in all
          such respects.

     31.2 A  Certificate  of  Competence  issued  to  an  Approved  Contractor's
          employee  in  accordance  with this  paragraph  4 shall  certify  that
          employee's  suitability  to perform Works on the  Distribution  System
          subject to a Permission.  The Approved Contractor shall be responsible
          for giving the Company a copy of each Certificate of Competence issued
          by it, for reissuing or revoking each  Certificate of Competence every
          three  years,  and for  maintaining  a record of all  Certificates  of
          Competence currently in force.


     31.3 A  Competent  Person  must  have a  valid  Certificate  of  Competence
          available for inspection at all times when performing any Works on the
          Distribution System. PROCEDURE FOR GRANTING PERMISSION

     32.1The User shall be entitled to procure the performance  of Works on the
          Distribution System by a Competent Person provided that the Competent
          Person  has a  valid  Permission.  The grant of a Permission  to a
          Competent Person shall not be unreasonably withheld, provided that the
          Company shall always have a prior right to undertake a trade test and
          safety awareness  assessment of that person and that the reasonable
          costs of  exercising this right  shall  be  paid  by  the Approved
          Contractor if requested by the Company.

     32.2 The nature,  scope,  and extent of the Works which a Competent  Person
          may undertake shall be at the Company's sole discretion.  A Permission
          shall  specify in writing the  categories of Works which the Competent
          Person is allowed to undertake  on the  Distribution  System,  and the
          Competent  Person's  authority to undertake  Works shall be limited to
          those categories alone and shall in no circumstances whatsoever extent
          to any other category of Works howsoever described.

    <PAGE>

     32.3 Notwithstanding anything in paragraph  5.2, the categories of Works
          specified  in  a  Permission  may (for  example only  and  without
          limitation)  include  any  of  the   following: 

          the withdrawal or  replacement  of  fuse  links in the service
          terminations;

          the connection or severing of wiring  between service terminations,
          meters and distribution boards;

          attendance at or the  performance of work in a  Distribution System
          substation without the need for personal supervision;

          the supervision or control of a working party which undertakes any of
          the above; and

          the  operating of high or low voltage switchgear.

          33.DISPUTES

          33.1The parties shall attempt to resolve in good faith any dispute in
               relation to assessment fees payable to the Company  pursuant to
               paragraph  3.1 of  this Schedule  7.  Where  a  dispute  remains
               unresolved  after 14 days either party may refer the dispute to
               the Director for determination. Any determination by the Director
               shall be final and binding.

                                 Demand Control



          INTRODUCTION



         The capacity and other technical parameters of the constituent elements
         which make up the Distribution System provide operational constraints
         on Demand and the coincidence of Demand.



          DEFINITIONS



          In  this Schedule 11, except where the context otherwise  requires,
          the following  expressions  shall have the meanings set opposite
          them:



          "Capacity  Headroom"  means a margin of 5 to 15 % below  the maximum
           capacity  of  the  Distribution   System  supplying  a  group  of
           Customers;



          "Compliance  Notice" means a notice  issued to a Supplier  pursuant to
           paragraph 8.5;

          "Effective Date" means the date that a notice issued  pursuant to this
           Schedule 11 is deemed  received in accordance  with Clause 24.5.2
           and/or paragraph 11.3 (as appropriate);



          "Emergency SRN" means a notice issued pursuant to paragraph 8.1;



          "Firm SRN" means a notice issued pursuant to paragraph 7.1;



          "Load Managed Area" means an area designated pursuan  to paragraph
           5.1;



         "Load Managed

          Area Notice" means a notice issued pursuant to paragraph 5.1;

          <PAGE>

         "Provisional SRN" means a notice issued pursuant to paragraph 6.1;
          
          "Security of  Supply"  means the  ability  of the  Company  to provide
           supplies to Customers,  that comply with the  Electricity  Supply
           Regulations and with ERP2/5 and ERP28;
     
          "SSC" means Standard Settlement Configuration;
     
          "Supplier" means a person authorised to supply electricity pursuant to
          section 6(1)(c) and/or section 6(2) of the Act; and
     
         "Total System"  has the meaning given to that term in the
          Distribution Code;



          36.GENERAL OBLIGATIONS



          3.1  The User shall use  reasonable  endeavours to ensure that it does
               not make any  changes  to SSCs in  force at  particular  Metering
               Points which have or may have a materially  adverse effect on the
               discharge   of  the   Company's   statutory   and/or   regulatory
               obligations to develop and maintain an efficient,  secure,  safe,
               co-ordinated  and  economical  system  for  the  distribution  of
               electricity  by  increasing  the  coincidence  of  Demand  on the
               Distribution  System in a way which is  likely  to  infringe  the
               Capacity  Headroom so that it is insufficient to allow for normal
               variations in Demand.

          3.2  The Company shall use  reasonable  endeavours to issue notices in
               Load Managed Areas in the following order:  Provisional SRN; Firm
               SRN and  Emergency  SRN and  normally not to issue a notice for a
               relevant  geographic area within 30 days of the Effective Date of
               the last notice for that relevant geographic area.
     
          37.CONSULTATION

         The User may at any time seek advice concerning operational constraints
         on the Distribution System from the Company on such reasonable terms as
         the parties may agree in writing.
     <PAGE>



          38.LOAD MANAGED AREAS



          5.1  The  Company  may  from  time  to  time  designate  areas  of the
               Distribution System as Load Managed Areas where the Company:



          38.1.1 has  identified  a need to  reinforce or extend the capacity of
               such  areas and  prior to  issuing a Load  Managed  Area  Notice,
               either:

               (A)  avoided the need for such reinforcement or extension through
                    a reduction in  coincidence  of Demand by adopting  Customer
                    Demand  management to control the timing of load  switching;
                    or

               (B)  reasonably  believes  that such  reinforcement  or extension
                    would be  avoided  through a  reduction  in  coincidence  of
                    Demand by Suppliers  adopting  Customer Demand management to
                    control the timing of load switching.

          5.2  A Load Managed  Area Notice shall be sent to the User,  all other
               Suppliers and the Director.

          5.3  A Load Managed Area Notice  shall be effective  when  received or
               deemed  received  in  accordance  with  Clause  24.5.2  and shall
               indicate:



               the geographical  area to which it applies by map,  postcode  or
               such other method as the Company considers reasonable;

               the  time or times of day during which in the  Company's opinion
               changes  to SSCs in  force  at particular  Metering  Points
               induced by  Suppliers  have  increased  the  coincidence  of
               Demand  to such an extent  that  Security  of Supply  may be
               threatened; and

               that it shall continue in force until withdrawn in writing by the
               Company by serving a notice on all Suppliers.



     5.4  The  parties  acknowledge  and agree that the issue of a Load  Managed
          Area Notice constitutes notice that:



          (i)  significant   modifications   of  Customer  Demand  in  the  area
               identified in such notice may threaten Security of Supply;

          (ii) Provisional  SRNs,  Firm SRNs and Emergency SRNs may be issued in
               respect of that area;

     <PAGE>
          


         (iii)    any future changes to SSCs in force at particular Metering
                  Points in that area may be subject at the request of the
                  Company to change in accordance with paragraph 7.5 or 8.5; and

          (iv) any changes to SSCs referred to in  paragraph  5.4(iii)  will if
               requested by the Company pursuant to paragraph  7.5 or 8.5 or if
               made voluntarily  by a Supplier be at the  relevant Supplier's
               cost.

     5.5  The Company may designate Load Managed Areas:

         5.5.1    any time up to and including 31 March 1998; and

         5.5.2 any time from [31 August 1998].


          (For the  avoidance of doubt,  the Company  shall not  designate  Load
          Managed  Areas  during the period  from 1 April 1998 to 30 August
          1998 inclusive).



     39.PROVISIONAL SECURITY RESTRICTION NOTICES



     6.1  The  Company  may  from  time to time  issue  a  Provisional  Security
          Restriction  Notice where in the Company's opinion the changes to SSCs
          in force at particular  Metering  Points since the Effective Date of a
          Load Managed Area Notice have  increased the  coincidence of Demand in
          the  whole  or part of the area  identified  in that  notice  so as to
          materially infringe the Capacity Headroom on such area since the issue
          of that notice.

     6.2  A Provisional  SRN shall be sent to the User, all other  Suppliers and
          the Director.

     6.3  A Provisional  SRN shall be effective when received or deemed received
          in accordance with Clause 24.5.2 and shall indicate:



          the geographical  area to which it applies by map,  postcode  or such
          other method as the Company considers reasonable;

          the  time or times of day  during  which  Capacity  Headroom  has been
          infringed  from  the  Effective  Date of the  Load  Managed  Area
          Notice; and

          that it shall  continue  in force  until  withdrawn  in writing by the
          Company by serving a notice on all Suppliers.

     <PAGE>


     6.4  The parties  acknowledge and agree that the issue of a Provisional SRN
          constitutes notice that:


          (i)  any  modifications  of Customer Demand induced by changes to SSCs
               in the area  identified  in such notice may threaten  Security of
               Supply;

          (ii) Firm SRNs and  Emergency  SRNs may be issued in  respect  of that
               area and that such notices will  normally not be issued within 30
               days of the Effective Date of the relevant Provisional SRN;

         (iii)    any future changes to SSCs in force at particular Metering
                  Points in that area may be subject at the request of the
                  Company to change in accordance with paragraph 7.5 or 8.5 ;
                  and

         (iv)     any changes to switching times in order to effect changes to
                  SSCs referred to in paragraph 6.4(iii) will if requested by
                  the Company pursuant to paragraph 7.5 or 8.5 or if made
                  voluntarily by a Supplier be at the relevant Supplier's cost.



     40.FIRM SECURITY RESTRICTION NOTICES



     7.1  The  Company may from time to time issue a Firm  Security  Restriction
          Notice where in the Company's  opinion the changes to SSCs in force at
          particular  Metering Points since the Effective Date of a Load Managed
          Area Notice have  increased the  coincidence of Demand in the whole or
          part of the area  identified in that notice and as a result there is a
          material risk to Security of Supply.


     7.2  A Firm SRN shall be sent to the  User,  all  other  Suppliers  and the
          Director.



     7.3  A Firm SRN shall be  effective  when  received  or deemed  received in
          accordance with Clause 24.5.2 and shall indicate:



          the geographical  area to which it applies by map, postcode  or such
          other method as the Company considers reasonable;

          the time or times of day during which Capacity  Headroom is infringed
          and into which  Demand  cannot be moved as a result of changes to
          switching times by Suppliers;

          the  time or times of day during which there is sufficient capacity at
          the  Effective  Date of the  Firm SRN into  which  Demand  can be
          moved; and

     <PAGE>


          that it shall  continue  in force  until  withdrawn  in writing by the
          Company by serving a notice on all Suppliers.



     7.4  The  parties  acknowledge  and  agree  that the issue of a Firm SRN
          constitutes notice that:



          (i)  any  modifications  of Customer Demand induced by changes to SSCs
               in the area  identified  in such notice may threaten  Security of
               Supply;

          (ii) Emergency  SRNs may be  issued in  respect  of that area and that
               such  notices will  normally not be issued  within 30 days of the
               Effective Date of the relevant Firm SRN;

          (iii)any  future  changes  to SSCs in  force  at  particular  Metering
               Points in that area may be subject at the  request of the Company
               to change in accordance with paragraph 7.5 or 8.5; and

          (iv) any changes to switching times in order to effect changes to SSCs
               referred  to in  paragraph  7.4(iii)  will  if  requested  by the
               Company  pursuant to paragraph 7.5 or 8.5 or if made  voluntarily
               by a Supplier be at the relevant Supplier's cost.

     7.5  When the Company issues a Firm SRN it may where it reasonably believes
          that SSCs  allocated in respect of the  Customers of a Supplier  since
          the  Effective  Date of the  relevant  Load  Managed  Area  Notice  or
          Provisional SRN have materially contributed to the risk to Security of
          Supply in respect of which the Firm SRN has been  issued,  also send a
          separate notice to that Supplier and a copy to the Director, requiring
          it to change at the Supplier's  cost within such period of time as the
          Company considers  reasonable the SSCs in force at particular Metering
          Points  in the  area  designated  in the  Firm SRN to the SSCs for the
          relevant  Metering  Points  at the  Effective  Date  of  the  relevant
          Provisional  SRN  or  where  the  Company  reasonably  believes  it is
          necessary  to such other SSCs as shall not have a  materially  adverse
          effect on  Security  of Supply  or to take  such  other  action as the
          Company considers reasonable.



     41.EMERGENCY SECURITY RESTRICTION NOTICES



     8.1  The Company may at any time issue an  Emergency  Security  Restriction
          Notice where in the Company's  opinion  there is an immediate  risk to
          Security  of  Supply.  (For the  avoidance  of doubt  the  issue of an
          Emergency SRN shall not be restricted to Load Managed Areas).

     8.2  An Emergency  SRN shall be sent to the User,  all other  Suppliers and
          the Director.



     <PAGE>

     8.3  An Emergency SRN shall be effective  when received or deemed  received
          in accordance with paragraph 11.3 below and shall indicate:



          the  geographical  area to which it applies by map,  postcode  or such
          other method as the Company considers reasonable;

          the  time or times  of day  into  which  Demand  cannot  be moved as a
          result of changes to switching times by Suppliers;

          the  time or times of day during which there is sufficient capacity at
          the Effective  Date of the Emergency SRN into which Demand can by
          moved; and

          that it shall  continue  in force  until  withdrawn  in writing by the
          Company by serving a notice on all Suppliers.

     8.4  The parties  acknowledge  and agree that the issue of an Emergency SRN
          constitutes notice that:



          (i)  any  modifications  of Customer Demand induced by changes to SSCs
               in the area  identified  in that notice may threaten  Security of
               Supply;

          (ii) any future changes to SSCs in force at particular Metering Points
               in that  area may be  subject  to  reversion  to the SSCs for the
               relevant  Metering  Points at the Effective Date of the Emergency
               SRN or such  other  SSCs as shall not have a  materially  adverse
               effect on Security of Supply; and

          (iii)any  changes  to  switching  times in order to effect  changes to
               SSCs  referred to in  paragraph  8.4(ii) will if requested by the
               Company be at the relevant Supplier's cost.

     8.5  When the Company  issues an Emergency  SRN it may where it  reasonably
          believes that SSCs allocated in respect of the Customers of a Supplier
          have  materially  contributed  to the risk to  Security  of  Supply in
          respect  of which  the  Emergency  SRN has been  issued,  also  send a
          Compliance  Notice  to that  Supplier  and a copy to the  Director.  A
          Compliance  Notice  shall  require  the  Supplier  to  change  at  the
          Supplier's  cost within  such period of time as the Company  considers
          reasonable the SSCs in force at particular Metering Points in the area
          designated in the Emergency SRN to the SSCs for the relevant  Metering
          Points at the  Effective  Date of the  relevant  Firm SRN or where the
          Company  reasonably  believes  it is  necessary  to such other SSCs as
          shall not have a materially adverse effect on Security of Supply or to
          take such other action as the Company considers  reasonable.  PROVIDED
          that where the  Company  requires  changes to SSCs in an area which is
          not a Load Managed Area or to SSCs which have not been modified by the
          Supplier  since the  Effective  Date of the current  Load Managed Area
          Notice then the cost of Meter Operator  visits required to affect such
          changes shall be at the Company's cost.


     <PAGE>



     8.6  Failure to Comply with an Emergency  SRN or a Compliance  Notice shall
          constitute  a breach of this  Agreement  and the  Company  may with no
          prior notice to the User where the User is in such breach  De-energise

                                   SCHEDULE 12

                          Standard Connection Agreement

                          Standard Terms of Connection

          (A)  The electricity you receive from your electricity  supplier will
               be  delivered  using the  distribution network run by your local
               network operator.  To receive a supply of electricity you require
               both:

               a connection  agreement  with your local  network  operator to
               maintain the connection of your premises to the network; and

               a supply contract with your electricity supplier.

          (B)  Your electricity supplier has been appointed as the agent of your
               local network operator to obtain a connection agreement with you
               on these standard  terms.  When you enter into your electricity
               supply contract, you are also  entering  into  this connection
               agreement with your local network operator.

          (1)Interpretation:  In this agreement the terms "we", "our" and "local
               network  operator" mean, for each connection to a network through
               which you are supplied under your  electricity  supply  contract,
               the  public  electricity  supplier  which owns or  operates  that
               network.

          (2)  Existing terms: Any existing terms applying to your connection to
               our  network  (except  for our tariff  terms or another  standard
               connection agreement) will apply instead of this agreement to the
               extent  that  they are  inconsistent  with  this  agreement.

          (3)  Duration  of this  connection  agreement:  This  agreement  takes
               effect from the time that your electricity  supply contract takes
               effect  and  will  continue  (even  if  your  electricity  supply
               contract  ends)  until  it  ends  under  Clause  11  below. 

          (4)  Connection to our network: Your premises will remain connected to
               our network in accordance  with the provisions of the Electricity
               Act 1989,  any other legal  requirements  that apply from time to
               time, and the terms of this agreement.

          (5)  Network  constraints:  Our  obligations  under this agreement are
               subject to the maximum  capacity and any other design  feature of
               your  connection.  In accordance  with existing legal rules,  you
               must contact us in advance if you propose to make any significant
               change  to  your   connection,   electric   lines  or  electrical
               equipment, install or operate generating equipment or do anything
               else that could affect our network or require alterations to your
               connection.

          (6)  Delivery of electricity: We do not guarantee that we will deliver
               electricity  through our network at all times or that electricity
               delivered through our network will be free of brief variations in
               voltage or frequency.

          (7)  Cutting off your supply: We may cut off the supply of electricity
               to your  connection  where we are  entitled  to do so  under  the
               general law. We may also cut off your supply of electricity where
               we are required to do so under your  electricity  supply contract
               or the electricity industry arrangements under which we operate.


<PAGE>


          If something goes wrong:  If we fail to comply with any term of this
          agreement,  or are  negligent,  you  may be  entitled  under  the
          general law to recover compensation from us for any loss you have
          suffered.  However, we will not be required to compensate you for
          loss caused by anything beyond our reasonable control, or for any
          indirect,  consequential,  economic or financial loss  (including
          losses of revenue, profit or opportunity, wasted expenses or loss
          of contract or  goodwill),  other than where you are  entitled to
          recover  compensation  for such  loss  under the  general  law in
          relation to death or personal injury.

          (8)  Business customers: If the electricity supplied to your premises
               is used wholly or mainly for business  purposes, each of us will
               only be liable to the other in accordance with the limitations in
               Clause 8 and up to a maximum of (pound)100,000 per calendar year.

          (9)Changing this connection  agreement:  The terms of this connection
               agreement  will  be  changed  automatically  to  incorporate  any
               changes which are approved by the Director General of Electricity
               Supply.  Any change  which is approved  will be  announced  in at
               least three national  daily  newspapers and will take effect from
               the date stated in those announcements. 

               Either of us may ask the other to accept a change to any part of
               this agreement at any time if either  believes the change is
               needed  because of the nature of your  connection or because
               this  agreement  is no longer  appropriate.  (It is unlikely
               that we will propose any changes  unless your  connection is
               at high voltage,  you have generating equipment or there are
               other special  features.) If a change is proposed under this
               clause,  and  cannot  be agreed  between  us within 28 days,
               either of us may ask the  Director  General  of  Electricity
               Supply to decide whether or not the change should be made.

          (10)Ending this connection agreement:  This agreement will end in
              relation to a connection when one of the following occurs:

              you begin to take your electricity supply through  that
              connection from us on our tariff terms;

              you permanently stop having  electricity  delivered through that
              connection;

              you no longer either own or occupy the  premises at which that
              connection is situated; or

              any circumstances arise which legally entitle us to cut off your
              electricity  supply to that connection  and we write to you
              advising you that this agreement is ended.

     The ending of this  agreement  will not affect  any  rights,  remedies  or
     obligations  which may have come into being under this  agreement  and
     Clauses 8 and 9 will continue to apply to those  rights,  remedies and
     obligations.

          (11)Transferring  this connection  agreement:  You are not entitled to
               transfer this agreement to another person without our consent.

          (12) Providing  information:  You must provide us with any information
               we  request  in  relation  to  the  nature,  or use  by  you,  of
               electrical  equipment  on your  premises.  We will  only  ask for
               information  that we need in  relation to this  agreement  or the
               Distribution  Code  that  applies  under our  Public  Electricity
               Supply Licence.

                          STANDARD CONNECTION AGREEMENT
                          Standard Terms of Connection


A. The electricity you receive from your electricity supplier will be delivered
using the distribution network run by your local network operator. To receive a
supply of electricity you require both: . a connection agreement with your local
network operator to maintain the connection of your premises to the network; and
 . a supply contract with your electricity supplier.

B.Your electricity supplier has been appointed as the agent of your local
network operator to obtain a connection agreement with you on these standard
terms. When you enter into your electricity supply contract, you are also
entering into this connection agreement with your local network operator.

1.Interpretation: In this agreement the terms "we", "our" and "local network
operator" mean, for each connection to a network through which you are supplied
under your electricity supply contract, the public electricity supplier which
owns or operates that network.

2.Existing Terms:Any existing terms applying to your connection to our network
(except for our tariff terms or another standard connection agreement) will
apply instead of this agreement to the extent that they are inconsistent with
this agreement.

3.Duration of this connection agreement:This agreement takes effect from the
time that your electricity supply contract takes effect and will continue (even
if your electricity supply contract ends) until it ends under Clause 11 below.

4.Connection to our network: Your premises will remain connected to our network
in accordance with the provisions of the Electricity Act 1989, any other legal
requirements that apply from time to time, and the terms of this agreement.

5.Network constraints: Our obligations under this agreement are subject to the
maximum capacity and any other design features of your connection. In accordance
with existing legal rules, you must contact us in advance if you propose to make
any significant change to your connection, electric lines or electrical
equipment, install or operate generating equipment or do anything else that
could effect our network or require alterations to your connection.

6.Delivery of electricity: We do not guarantee that we will deliver electricity
through our network at all times or that electricity delivered through our
network will be free of brief variations in voltage or frequency.

7.Cutting off your supply: We may cut off your supply of electricity to your
connection where we are entitled to do so under general law. We may also cut off
your supply of electricity where we are required to do so under your electricity
supply contract or the electricity industry arrangements under which we operate.

8.If something goes wrong: If we fail to comply with any terms of this
agreement, or are negligent, you may be entitled under the general law to
recover compensation from us for any loss you have suffered. However, we will
not be required to compensate you for loss caused by anything beyond our
reasonable control, or for any indirect, consequential, economic or financial
loss (including loss of revenue, profit or opportunity, wasted expenses or loss
of contract or goodwill), other than where you are entitled to recover
compensation for such loss under the general law in relation to death or
personal injury.

9.Business customers:If the electricity supplied to your premises is used wholly
or mainly for business purposes, each of us will be liable to the other in
accordance with the limitations in Clause 8 and up to a maximum of
(pound)100,000 per calendar year.

10.Changing this connection agreement: The terms of this connection agreement
will be changed automatically to incorporate any changes which are approved by
the Director General of Electricity Supply. Any change which is approved will be
announced in at least three national daily newspapers and will take effect from
the date stated in those announcements.

Either of us may ask the other to accept a change to any part of this agreement
at any time if either believes the change is needed because of the nature of
your connection or because this agreement is no longer appropriate. (It is
unlikely that we will propose any changes unless your connection is at high
voltage, you have generating equipment or there are other special features.) If
a change is proposed under this clause, and cannot be agreed between us within
28 days, either of us may ask the Director General of Electricity Supply to
decide whether or not the change should be made.

11.Ending this  connection  agreement:This agreement will end in relation to a
connection  when one of the  following  occurs:  . you begin to take  your
electricity  supply through that  connection from us on our tariff terms: .
you permanently stop having electricity  delivered through that connection.
 . you no longer  either own or occupy the premises at which the connection
is situated;  or . any circumstances  arise which legally entitle us to cut
off your electricity  supplyto that connection and we write to you advising
you that this agreement is ended.

The ending of this agreement will not effect any rights, remedies or obligations
which may have come into being under this agreement and Clauses 8 and 9 will
continue to apply to those rights, remedies and obligations.

12.Transferring this connection agreement: You are not entitled to transfer this
   agreement to another person without our consent.

13.Providing information:You must provide us with any information we request in
relation to the nature, or use by you, of electrical equipment on your premises.
We will only ask for information that we need in relation to this agreement or
the Distribution Code that applies under our Public Electricity Supply Licence.
