                                       PART I

      Item 1. Description of Business

      Introduction
      The group is a leading multi-utility business in the U.K. serving
      approximately 5.5 million homes across Scotland, England and Wales. The
      map located on the inside front cover of this report indicates the
      location of the group's principal businesses. The group's activities
      span the generation, transmission, distribution and supply of
      electricity, gas supply, water supply and wastewater services,
      telecommunications, retailing of electrical appliances, technology and
      contracting services. ScottishPower and its subsidiaries comprise one
      of the largest industrial groups in the U.K., positioned around the
      middle of the FTSE 100 index, with an annual turnover in fiscal 1999 of
      over (Pounds)3.2 billion.

      Industry Background
      The U.K. electricity industry has undergone a period of rapid and
      dramatic change in the past decade. The sector has been restructured
      and its major players privatized and floated to the public by the U.K.
      government. Regulation is focused on encouraging cost reduction and
      productivity gains while increasing competition, and consolidation has
      brought further gains for shareholders and customers alike.

      Today, supported by an open and dynamic economy, the U.K. has recently
      completed another major change: full competition in the retail supply
      of electricity and gas services. The gas and electricity markets
      throughout Great Britain were fully opened to competition in May 1998
      and May 1999, respectively. This increased competition has spurred
      multi-utility convergence in the U.K. in a realignment affecting all
      segments of the utility industry.

      Business Strategy
      The group is committed to enhancing shareholder value through building
      businesses in electricity and utility related markets.

      The group has grown from a regional generator, distributor and supplier
      of electricity into a growing U.K. multi-utility business serving some
      5.5 million of the homes in Great Britain. This is due in large part to
      (i) the acquisition in 1995 of Manweb plc ("Manweb"), one of the twelve
      regional electricity companies created when the electricity utility
      industry in England and Wales was restructured in 1990, and (ii) the
      acquisition in 1996 of Southern Water plc ("Southern Water"), one of
      the ten water and wastewater service companies created when the water
      and wastewater industry in England and Wales was privatized in 1989.
      These acquisitions have allowed the group to expand both its customer
      base (by 1.3 million customers in the case of Manweb and 1.7 million
      customers in the case of Southern Water) as well as its geographic and
      product base by expanding into the electricity distribution and supply
      business in north-west England and Wales and into the water and
      wastewater business in southern England. The group has further
      leveraged its utility skills and assets in its expansion into the gas
      supply and telecommunications businesses. In domestic gas supply,
      ScottishPower is already established as a leading competitor to British
      Gas, with a total of 760,000 domestic contracts at the end of fiscal
      1999. Since the opening of the competitive electricity market, the
      Company has secured 190,000 new electricity contracts.

      Improving the efficiency of the group's businesses through a program of
      cost reductions is a key part of the strategy. In the Scottish energy
      businesses, the cost base has been significantly reduced since 1991
      through a process of benchmarking operations against other major
      companies around the world, both within and outside the utility sector.
      ScottishPower management has delivered substantial cost savings from
      both Manweb and Southern Water, totaling (Pounds)139 million to date.
      Management believes that further cost savings from the Scottish energy
      businesses, Manweb and Southern Water are achievable after fiscal 1999.

      The group intends to build its U.K. business primarily by exploiting
      the opportunity, and managing the challenge, of the deregulation of the
      electricity and gas supply markets and the telecommunications sector.
      The aim of the group's energy supply business will be to defend its
      existing base in the ScottishPower and Manweb areas, while exploiting

      the U.K.

      In addition, the company intends to utilize its excess capacity of
      efficient, coal-fired plant to continue to increase its share of the
      U.K. electricity generation market by exploiting expansion of the
      capacity of the Interconnector to the England and Wales market and the
      construction of an Interconnector between Scotland and Northern
      Ireland.

      ScottishTelecom's strategy has been to achieve growth through a
      combination of organic growth and selective acquisitions. This has
      provided ScottishTelecom with operations in key markets across the
      communications sector since its launch in 1994.

      ScottishTelecom now provides, under innovative tariff packages, a wide
      portfolio of communication services ranging from voice, data and mobile
      telephony services to call-center, on-line information and Internet
      access services.

      The development of the group has caused the Directors to review the
      future of ScottishTelecom. ScottishPower is currently evaluating the
      strategy of ScottishTelecom and the options available to maximize
      shareholder value from its investment in this business, in what is a
      rapidly changing and developing sector. This assessment includes a
      review of the services provided by ScottishTelecom, its funding needs
      and any consequential restructuring. The Directors expect to reach a
      decision during the year.

      Since privatization of the U.K. electricity industry in 1990-91, the
      group has experienced tightening regulation. Looking ahead it is
      expected that regulation will continue to have a material bearing on
      the profitability and investment capability of the group. The group's
      regulated monopoly businesses comprise electricity transmission and
      distribution in ScottishPower and electricity distribution in Manweb
      (together representing 44% of the group's fiscal 1999 operating
      profits) and the water supply and wastewater business in Southern Water
      (representing 30% of the group's fiscal 1999 operating profits). The
      regulatory price controls relating to these areas of the group's
      business for the five-year period commencing April 1, 2000 are
      currently being reviewed, and reviews are also taking place in relation
      to supply and generation. Nevertheless, the Board is unable to judge
      accurately the outcome of these reviews and there can be no assurance
      that they will not materially affect group profits. It is expected that
      final proposals resulting from these reviews will be known by November
      1999.

      Through organic growth and acquisitions, ScottishPower has laid the
      foundations for its U.K. business, creating a broadly based utility
      group that is strongly placed to add value for shareholders and
      customers.

      As well as continuing to drive for growth in its U.K. businesses, the
      group has explored international opportunities in the electricity
      sector. The focus has been on the United States, where management
      believes the cultural fit and the likely development of U.K.-style
      industry restructuring and convergence offers opportunities to deliver
      shareholder value by applying the group's core skills.

      Proposed ScottishPower--PacifiCorp Merger
      On December 7, 1998, the boards of ScottishPower and PacifiCorp
      announced that they had reached agreement on the proposed merger of
      their two companies. Under the terms of the Merger, PacifiCorp common
      shareholders (other than ScottishPower or any subsidiary of
      ScottishPower or PacifiCorp) will be entitled to receive 0.58
      ScottishPower ADSs, which will be listed on the New York Stock
      Exchange, or 2.32 ordinary shares of ScottishPower, which will be
      listed on the London Stock Exchange, for each share of PacifiCorp they
      own. ScottishPower shareholders will continue to own their existing
      shares after the Merger.

      The Combined Group intends to account for the Merger using the
      acquisition method of accounting under U.K. GAAP and using the purchase
      method of accounting under U.S. GAAP. The Merger is subject to a number
      of conditions, including its approval by both the ScottishPower
      shareholders and the PacifiCorp shareholders which were recently
      obtained. The Merger is also conditional on a number of regulatory, tax
      and other consents and confirmations in the U.S. and the U.K. The
      Merger is expected to be completed this year.

      The Merger will create an international utility company with
      significant energy businesses in the U.K. and the U.S. with
      approximately seven million customers. The Directors believe that
      significant benefits will be derived from the Merger and that the
      Combined Group will be more operationally efficient and stronger
      financially than either ScottishPower or PacifiCorp would be on its
      own. The Merger is expected to enhance New ScottishPower's or
      ScottishPower's, as applicable, earnings per share, before goodwill
      amortization, from the first full year after

ScottishPower Form 20-F 1999                                                   7
<PAGE>

      completion of the Merger compared to the Directors' present
      expectations for the existing group. See "Scheme of Arrangement" below.
      The Merger represents a major step in ScottishPower's stated strategy
      of achieving growth and creating value for shareholders by utilizing
      its core skills in the U.S.

      ScottishPower has carried out detailed analyses of the U.S. market and
      possible combination partners. The Directors believe that PacifiCorp is
      an excellent partner, in that it combines:

      . a sound business, good quality assets and an extensive customer base
        in a region of the U.S. benefiting from good economic growth;

      . substantial scope for improved performance and efficiency;

      . experienced operational management; and

      . low-cost coal resources and generation plant.

      The Combined Group will focus on accelerating PacifiCorp's strategy to
      improve the performance of its western U.S. electricity business.
      ScottishPower and PacifiCorp believe that the application of best
      practices of the two companies will reduce costs and increase operating
      efficiencies with the goal of enhancing shareholder value. Although it
      is difficult to predict the source of cost savings, the Directors
      expect most, if not all, of the anticipated cost savings to come from
      the application of best practices in operational and overhead areas
      rather than through elimination of costs duplicated between
      ScottishPower and PacifiCorp. The Directors believe that this will
      enable PacifiCorp, which has recently suffered from a period of
      financial under-performance, to achieve more quickly its stated aim of
      earning the authorized regulatory rate of return in each U.S. state in
      which it conducts business and will bring PacifiCorp's non-generation
      costs per customer in the U.S. in line with some of the most efficient
      comparable utilities, based on comparisons drawn from information filed
      with FERC.

      To assist the delivery of these improvements, the Directors intend to
      transfer a number of senior managers with integration experience into
      PacifiCorp. Some PacifiCorp managers will also be transferred into
      ScottishPower's U.K. operations to gain experience of ScottishPower's
      working practices.

      The Merger should enable ScottishPower to apply its proven utility
      management skills to PacifiCorp. The Directors believe that these
      skills, developed in the competitive U.K. market, will assist
      PacifiCorp as competition is introduced into the U.S. generation and
      supply businesses.

      The Directors also intend to enhance significantly the performance and
      service standards of PacifiCorp, and to increase the range of energy
      services offered to PacifiCorp customers, by investing in PacifiCorp's
      existing U.S. businesses and by applying the best practices drawn from
      both ScottishPower and PacifiCorp. ScottishPower and PacifiCorp share a
      common commitment to high standards of customer service, to the
      environment and to the communities they serve.

      Earnings and Dividends
      The Merger should, when completed, create one of the largest
      international utility companies and open up more growth opportunities
      for the Combined Group.

      The Merger is expected to be earnings enhancing from the first full
      year, before goodwill amortization, compared to the Directors' present
      expectations for the existing group.

      ScottishPower's stated dividend aim is to achieve 7% to 8% real
      dividend growth per annum until at least the U.K. regulatory reviews
      which take effect in the year 2000, whilst maintaining a prudent level
      of dividend cover. It is ScottishPower's current aim to deliver real
      dividend growth thereafter and this will be re-examined once the
      outcome of the regulatory reviews is known.

      Scheme of Arrangement
      The company announced on February 25, 1999 its intention to recommend
      to ScottishPower shareholders a proposal to introduce a new holding
      company for the group, New ScottishPower (to be renamed Scottish Power
      plc upon the scheme becoming effective). The holding company structure
      will be effected through a "scheme of arrangement" which must be
      sanctioned by a Scottish court and approved by ScottishPower's
      shareholders, which approval was recently obtained. Under the scheme,
      New ScottishPower will issue one share of New ScottishPower

8                                                   ScottishPower Form 20-F 1999


<PAGE>

      in exchange for each outstanding ScottishPower share. As a result, New
      ScottishPower will become the holding company for ScottishPower. The
      Merger with PacifiCorp is not conditional upon the scheme becoming
      effective nor is the scheme conditional upon the Merger becoming
      effective.

      In addition, ordinary shares of New ScottishPower will be listed on the
      London Stock Exchange, New ScottishPower ADSs will be listed on the New
      York Stock Exchange and New ScottishPower will be subject to the
      registration and information requirements of U.S. securities laws.

      The rights attaching to the New ScottishPower ordinary shares will be
      substantially the same as those currently attaching to the
      ScottishPower ordinary shares. Thus, after the scheme is implemented,
      holders of ScottishPower ordinary shares will have their interest in
      ScottishPower replaced by an equivalent proportionate interest in New
      ScottishPower and, subject to the effect of exercise of options to
      subscribe for ScottishPower shares granted under ScottishPower share
      schemes, their proportionate interests in the profits, net assets and
      dividends in the group will not be affected.

      If the scheme of arrangement is not implemented by June 30, 2000, the
      holders of ScottishPower shares will remain as such, ScottishPower
      ordinary shares will continue to be listed on the London Stock Exchange
      and its ADSs will continue to be listed on the New York Stock Exchange.

      If the scheme is sanctioned by the court and the conditions to the
      scheme are satisfied or waived, it is expected to become effective on
      July 30, 1999.

      Share Buy-back
      The Directors started a share buy-back program of up to (Pounds)500
      million following approval of the Merger by both ScottishPower
      shareholders and PacifiCorp shareholders. This is intended to achieve
      further financial efficiency, with an expected net interest cover of
      approximately three times, while targeting an "A" credit rating. The
      buy-back is being undertaken through on-market purchases.

      Outlook
      Apart from the many changes and opportunities which the year ahead
      offers in the U.K. operations, it is expected the PacifiCorp merger
      will be completed later this year. This would make ScottishPower one of
      the top 10 electricity companies in the world and would bring the total
      employment complement in the new enlarged group to 25,000.

      Looking forward into the new millennium, regulation will continue to
      have a significant bearing on the profitability and investment
      capability of the group. The Directors believe that the group has high
      standards of operation and customer service. Nevertheless, they are
      unable to judge accurately the outcome of the current U.K. regulatory
      reviews and there can be no assurance that they will not materially
      affect the group's profits.

      ScottishPower's goal is to provide better service and value to
      customers and at the same time enhanced earnings for shareholders. This
      must be supported by a process of regulation which takes a balanced
      long-term view to reward investment and encourages improvements in
      service and efficiency.

      ScottishPower will continue its strategy to develop and grow the
      business. This will require ongoing revenue and capital investment in
      the year ahead. ScottishPower is confident in its strategy for long-
      term growth and, given the quality of the company and its people, looks
      forward to further success.

      Structure of the Electricity Industry in the United Kingdom
      The U.K. electricity industry, which was restructured in March 1990 to
      introduce competition into the generation and supply of electricity,
      consists of the following activities:

      Generation:     the production of electricity at power stations

      Transmission:   the bulk transfer of electricity across a high voltage
                      transmission system

      Distribution:   the transfer of electricity from the high voltage
                      transmission system and its delivery, across local low
                      voltage distribution systems, to customers

      Supply:         the bulk purchase of electricity by suppliers and its
                      sale to customers, with the associated customer service
                      activities including sales and marketing, billing and
                      income collection

      The U.K. has three distinct geographical systems: Scotland, England &
      Wales and Northern Ireland, each with a different commercial framework.
      The Scottish and English systems are interconnected, and an agreement
      has been reached for the construction of a link between Scotland and
      Northern Ireland.

      In each of Scotland and England & Wales, the electricity industry is
      regulated under the Electricity Act 1989 (the "Electricity Act") by the
      Secretary of State for Scotland or the Secretary of State for Trade and
      Industry, as applicable (collectively, the "Secretary of State"), and
      the Director of Electricity Supply (the "DGES"). See "Regulation of the
      Electricity Industry". The chart below provides an overview of the
      electricity industry in Great Britain.

      Industry Structure in Scotland
      The electricity industry in Scotland is principally comprised of two
      vertically integrated companies, ScottishPower and Scottish & Southern,
      each generating, transmitting, distributing and supplying electricity
      within their respective franchise areas. A third, Scottish Nuclear, a
      subsidiary of British Energy, is primarily a generator selling all the
      electricity it generates at its two nuclear power stations in Scotland
      to ScottishPower and Scottish & Southern under the Nuclear Energy
      Agreement (the "NEA").

      Generation ScottishPower and Scottish & Southern generate electricity
      from their own portfolio of power stations. In addition the companies
      are obliged, under the NEA, to purchase the entire output from Scottish
      Nuclear. A number of further contractual relationships exist between
      the two companies which involve the sharing of coal-fired, dual oil and
      gas-fired and conventional hydro generating capacity by allocating part
      of the capacity of certain generating stations operated by one company
      to the other company. See "Generation Wholesale--Generation Portfolio"
      for further discussion of these contractual arrangements. Currently,
      there exists a surplus of generating capacity in Scotland which enables
      the companies to sell electricity to England and Wales through the
      Interconnector. The quantity of these sales is set to increase as the
      current transmission constraints are reduced.

      Transmission The transmission systems of ScottishPower and Scottish &
      Southern are each made up of a network comprised of overhead lines,
      underground cables and associated equipment operating at either 275 kV
      or 132 kV and, in the case of ScottishPower, 400 kV. This network
      connects the generating stations and distribution entry points
      operating at, or below, 33 kV. ScottishPower's transmission system is
      connected to the national grid in England and Wales by the
      Interconnector. Both companies have access to this link which enables
      the companies to export and import electricity from England and Wales.
      The available capacity of the Interconnector at any time depends on a
      number of variable factors, (e.g., the secure thermal rating of the
      Interconnector circuits and the pattern of scheduled generation on
      either side of the border). In fiscal 1999, the average level of
      exports on the Interconnector was 1,427 MW.

      Distribution The distribution systems are each made up of a network of
      overhead lines and underground cables operating at either 33 kV, 11 kV,
      415 volts or 230 volts. The distribution voltages and equipment used
      are determined by end users' requirements and their location and by the
      relative economics of transferring electricity at different voltages.
      To ensure competition in the supply business, the companies are
      required to provide open access to their transmission and distribution
      networks on a non-discriminatory basis.

      Supply The energy supply business purchases electricity from a range of
      sources, including the group's generation business, for sale to
      customers both within its home areas and outside them.

      Industry Structure in England and Wales
      In England and Wales, electricity is produced by generators, the
      largest of which are National Power plc, PowerGen plc and Nuclear
      Electric plc, a subsidiary of British Energy, and the Energy Group plc.
      Electricity is transmitted through the national grid transmission
      system by NGC and distributed by the 12 RECs (one of which is Manweb)
      in their respective franchise, or authorized, areas. Most customers are
      currently supplied with electricity by their local REC, although there
      are other suppliers holding second tier supply licenses, including
      other generators and RECs, who can also compete to supply customers.

      Generation Virtually all electricity generated in England and Wales is
      sold by generators and bought by suppliers through the Pool. The Pool
      was established at the time of privatization for bulk trading of
      electricity in England and Wales between generators and suppliers. All
      licensed generators and suppliers must become signatories to the
      Pooling and Settlement Agreement governing the constitution and
      operation of the Pool and the calculation of payments due to and from
      generators and suppliers. The Pool also provides centralized settlement
      of accounts and clearing. As discussed above, ScottishPower and
      Scottish & Southern can participate in the Pool by exporting
      electricity to or importing electricity from England and Wales via the
      Interconnector.

      Prices for wholesale electricity sales 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. A computerized
      system (the settlement system) is used to calculate prices and to

12                                                  ScottishPower Form 20-F 1999


<PAGE>

      process metered, operational and other data and to carry out the other
      procedures necessary to calculate the payments due under the Pool
      trading arrangements. Because Pool prices tend to be volatile and
      difficult to predict, generators and suppliers often enter into
      bilateral arrangements, such as contracts for differences, to provide a
      degree of protection against such fluctuations.

      In October 1997, HM Government requested the DGES carry out a review
      into wholesale electricity trading arrangements in England and Wales to
      advise on whether, and if so what, changes should be made. Under the
      terms of reference of the review, the new trading arrangements being
      considered would be required to be transparent, efficient and risk
      reducing while meeting customers needs, promoting competition and
      avoiding discrimination. The DGES published proposals for new trading
      arrangements in July 1998 and these proposals were supported by HM
      Government in an Energy White Paper in October 1998. These arrangements
      will encompass the development of a balancing market, a short-term bi-
      lateral market and a related settlement system. The DGES is due to
      publish a further policy report in August 1999 with implementation of
      the new arrangements planned for fall 2000.

      Transmission NGC owns and operates the high voltage 275 kV and 400 kV
      electricity transmission system in England and Wales also known as the
      national grid. NGC has a statutory duty to operate a non-discriminatory
      policy both in the day-to-day administration of the system, and in the
      provision of access to the transmission network.

      Distribution The distribution businesses of the RECs operate and
      maintain the assets which carry power from grid supply points to
      individual customers within their authorized areas. This involves a
      network of overhead lines, underground cables, switches and
      transformers operating at voltages ranging from 132 kV down to 230
      volts in residential premises. To ensure competition in the supply
      business, the RECs are required to provide open access to their
      distribution networks on a non-discriminatory basis.

      Supply The supply business covers the bulk purchase of electricity
      through the Pool and the selling on to customers. RECs can supply
      customers within their authorized areas and holders of second tier
      licenses, subject to meeting certain requirements, can supply any
      customer. Second tier licenses are held by all the RECs, National Power
      plc, PowerGen plc, Nuclear Electric, ScottishPower, Scottish & Southern
      and some new suppliers.

      Competitive Framework
      Competition in supply has been progressively introduced in Scotland and
      in England and Wales. ScottishPower and Scottish & Southern in
      Scotland, and the RECs in England and Wales, are subject to competition
      from second tier suppliers for the supply of electricity to customers,
      including residential customers, in their respective franchise areas.

      Generation Wholesale
      The group's Generation Wholesale business ("Generation Wholesale")
      operates ScottishPower's generating stations and deals in the wholesale
      trading of electricity and gas. The business objective is to create
      competitive advantage for ScottishPower by optimizing the energy chain.

      Generation Portfolio
      ScottishPower's owned generation capacity comprises coal, gas, hydro
      and wind power and has available more than 3,500 MW after taking into
      account the impact of contractual obligations to supply Scottish &
      Southern with a proportion of its coal-fired capacity. In addition to
      its own capacity, ScottishPower also has access to nuclear energy, from
      British Energy Generation (U.K.) Limited, and gas-fired, oil-fired and
      hydro power from Scottish & Southern under contracts established in
      connection with the restructuring of the U.K. electricity industry in
      1990 and 1991. These resources combine to give ScottishPower a flexible
      fuel portfolio and result in total available capacity of some 6,400 MW.
      ScottishPower's available capacity in Scotland is significantly greater
      than the demand it is required to meet. Additional information
      concerning the group's generating capacity, either owned or available
      under contract, is set out on the following two pages.

     /1/The NEA entitles ScottishPower and Scottish & Southern to 74.9% and
        25.1%, respectively, of the electricity generated from British Energy's
        Hunterston B and Torness nuclear generating stations. Except in limited
        circumstances, the NEA obliges ScottishPower and Scottish & Southern to
        pay for all the electricity declared by British Energy to be available
        from such nuclear stations, whether or not they take such electricity.
     /2/Following the end of the Miller Gas Plateau, ScottishPower is entitled
        to 50% of the net output capacity of Scottish & Southern's Peterhead
        station (or such lesser part of that capacity as Scottish & Southern
        declares to be available to ScottishPower on any day).
     /3/The gas turbines installed at Peterhead are primarily for use during an
        outage on one of the main units at the station to enable the consumption
        of the gas delivered from the Miller gas field. The use of the gas
        turbines at other times is subject to agreement with Scottish &
        Southern.
     /4/The Hydro Agreement entitles ScottishPower to 400 GWh of electricity
        from Scottish & Southern's conventional hydro generating capacity during
        each contract year (although this amount may be reduced during periods
        of unusually low rainfall or unusually low run-off) and requires
        ScottishPower to pay for that amount of electricity, irrespective of how
        much electricity it actually takes.

      Station Performance
      Generation Wholesale's goal is to achieve best practice in terms of
      generation performance and costs, at the same time maintaining the
      flexibility to optimize energy trading.

      Generation Wholesale has undertaken extensive benchmarking of all its
      activities against an international peer group and undertaken programs
      to implement its findings. However, it is the intention of the business
      to drive costs down further through continued reductions in fixed costs
      and manpower plus improved engineering efficiencies and enhanced
      environmental performance. The group has a detailed engineering
      strategy to upgrade its existing coal stations. Furthermore, management
      believes that, as a result of its ongoing maintenance program,
      ScottishPower's portfolio of power stations is in a condition to
      support current and expected generation output.

      Fuel Strategy and Sourcing
      ScottishPower's fuel purchasing strategy is based upon the objective of
      achieving competitive fuel prices while balancing the need for security
      and flexibility of supply. The major components of the fuel portfolio
      are coal, gas and oil.

      Coal -- ScottishPower currently purchases the majority of its coal from
      Scottish suppliers under long-term contracts, with the principal
      supplier being The Scottish Coal (Deep Mine) Limited. Under a six year
      deal which
ScottishPower Form 20-F 1999                                                  15
<PAGE>

      commenced on April 1, 1998, ScottishPower will take 1.67 million tonnes
      per annum of low sulphur coal from Scottish Coal's Longannet Deep Mine
      Complex, adjacent to the Longannet Power Station.

      Up to a further 1.7 million tonnes of Scottish opencast coal will also
      be supplied yearly by other Scottish suppliers under long-term
      contracts of between three and five years, which commenced on April 1,
      1998.

      These purchase commitments secure the major part of ScottishPower's
      coal requirements from local sources at competitive prices. The balance
      of requirements will be sourced through the exercise of options under
      the long term contracts and/or short term competitive tenders,
      depending on market conditions.

      Gas -- ScottishPower purchases gas to meet the needs of the group's
      generation and supply businesses. Balancing and trading of gas is the
      responsibility of the Energy Trading Center.

      The group's gas purchasing strategy is based upon a combination of
      long, medium and short-term contracts. In accordance with this
      strategy, the group has agreed contracts direct with gas producers for
      the supply of gas on a non-interruptible basis. The group has two long
      term contracts (with terms of, respectively, 10 and 15 years, from
      1994) for supply from major gas fields. In addition, ScottishPower is
      party to agreements which require Scottish & Southern to purchase and
      accept delivery of gas from the Miller gas fields at Peterhead power
      station. These agreements continue in force until the reserves of the
      field have been fully depleted. Latest projections are that this could
      occur within the next two to three years. It should be noted that
      ScottishPower is continuing to look at opportunities which might be
      available for it to participate in the Peterhead repowering project
      which will upgrade the station to combined cycle gas turbine status.

      Oil -- From time to time, ScottishPower purchases heavy fuel oil on the
      international spot market when favorable prices are available. Heavy
      fuel oil is therefore an opportunity purchase rather than a firm fuel
      source.

      Generation Sales
      Generation sales totalled 29,679 GWh in fiscal 1999. Approximately
      22,246 GWh were attributable to ScottishPower's energy supply business,
      with the remaining 7,433 GWh either being sold to other suppliers or
      exported via the Interconnector to the Pool in England and Wales.

      The average utilization of ScottishPower's two largest coal-fired
      stations, Longannet and Cockenzie, in fiscal 1999 was approximately 46%
      and 26%, respectively. It is expected that this utilization will
      increase as the capacity of the Interconnector is progressively
      expanded enabling ScottishPower to sell greater quantities of
      electricity into the Pool.

      The Pool in England and Wales
      ScottishPower has the ability to sell, or purchase electricity through,
      the Pool in England and Wales via the Interconnector which is shared by
      Scottish & Southern and BNFL under formal agreement. See "Structure of
      the Electricity Industry in the United Kingdom--Industry Structure in
      England and Wales" for a general discussion of the Pool. The current
      maximum capacity of the Interconnector is 1,950 MW with an average in
      fiscal 1999 of 1,427 MW. As ScottishPower produces electricity for
      significant periods of the year at a cost that is below the price at
      which the Pool purchases electricity, ScottishPower is able to take
      advantage of the prices at which electricity is purchased and sold by
      the Pool.

      The ScottishPower network is also connected at several points to the
      transmission network of Scottish & Southern. An agreement has been made
      with the NGC and Scottish & Southern to upgrade the maximum capacity of
      the Interconnector to 2,200 MW. Planning approval has now been granted
      by HM Government for the reinforcement necessary in England and Wales
      to give full effect to the upgrade. The current completion date for
      this project is September 2001. ScottishPower's generation business
      will provide 75% of the capital cost of the upgrade. Pursuant to an
      agreement with Scottish & Southern, ScottishPower has the contractual
      right to 54% of the pre-upgrade capacity and up to 75% of the
      additional upgrade capacity of the Interconnector.

      ScottishPower's Composite License only entitles it to reserve capacity
      to itself with the consent of the DGES, and obliges it to offer to
      enter into an agreement with a third party applicant for use of the
      Interconnector, except when

<PAGE>

      the DGES determines that the capacity of the Interconnector is
      insufficient to accommodate the requirements of the applicant having
      regard to such amounts of capacity as has already been reserved to
      ScottishPower (with the DGES's consent) or a third party. The DGES
      determined, in December 1998, that ScottishPower may not reserve any of
      its allocated capacity on the Interconnector to its own generation
      business. The DGES also determined that capacity was sufficient to
      accommodate the requirements of BNFL, and specified that ScottishPower
      should make available to BNFL up to 196 MW of capacity for the period
      January 1, 1999 to March 31, 2002. In the case of National Power plc,
      the DGES declined to make a determination on the grounds that National
      Power plc had not provided sufficient information in support of its
      application. Following these determinations, ScottishPower has made
      applications to the DGES to reserve capacity of 75% of the additional
      upgrade capacity to itself and, with respect to the existing capacity,
      is in negotiation with the DGES with respect to amendments to the rules
      governing the allocation of capacity.

      The determinations referred to above resulted from requests to
      ScottishPower from BNFL and National Power plc for access to the
      Interconnector, and a request by ScottishPower that the whole of the
      capacity on the Interconnector to which ScottishPower is contractually
      entitled be reserved to ScottishPower's generation business. On March
      31, 1999, ScottishPower extended on an interim basis its existing Use
      of Interconnector Agreement with BNFL, and negotiations are ongoing to
      enter into a new agreement to provide BNFL with access up to 196 MW per
      year until March 31, 2002 and potentially beyond to accommodate the
      remaining life of the Chapelcross power station. Without negating the
      December 1998 determination, ScottishPower contends that, under the
      existing contractual arrangements, Scottish & Southern is obliged to
      accommodate 46% of BNFL's required access. Scottish & Southern contends
      that all of BNFL's required access should be deducted from
      ScottishPower's share of access. Following discussions between
      ScottishPower and Scottish & Southern a compromise between the two
      positions has now been agreed in principle and will be ratified shortly
      in a formal agreement.

      Trading with Northern Ireland Electricity
      ScottishPower has entered into an agreement with Northern Ireland
      Electricity, a subsidiary of Viridian Group plc, for the construction
      of a Scottish-Northern Irish Interconnector with a transfer capability
      of 250 MW and an agreement for the supply by ScottishPower of around
      1,095 GWh of electricity per year over a period of 70 months from the
      date of commissioning. These agreements amend and restate agreements
      originally entered into in 1994. Once completed, the Northern Irish and
      marine sections of the Scottish-Northern Irish Interconnector will be
      owned by Northern Ireland Electricity, and the Scottish section from
      the converter station will be owned by ScottishPower. Northern Ireland
      Electricity will provide the full capital cost of this Interconnector.
      Approval has been obtained from the Northern Ireland Office for the
      Regulation of Electricity and Gas for this agreement although European
      Commission approval and U.K. competition clearance are still being
      sought. It is anticipated that the Scottish-Northern Irish
      Interconnector will commence commercial operation in December 2001.

      The capital cost to ScottishPower of both the England and Wales
      Interconnector upgrade and the construction of the link between
      Scotland and Northern Ireland are not considered material. Costs
      incurred will be recouped, by the company, through "use of system'
      charges on both projects.

      Power Systems
      ScottishPower owns and manages a substantial electricity network
      comprising both the distribution system to customers in its two
      authorized areas and, in Scotland, the high voltage transmission system
      (132 kilovolts and above). The latter includes all the assets of the
      Anglo-Scottish Interconnector which are in its Scottish authorized
      area. The main function of the power systems business ("Power Systems")
      is to develop and maintain an efficient, coordinated and economical
      network, including high voltage connections to England, and to operate
      and develop the distribution system to approved standards of safety and
      reliability. Within Power Systems the focus continues to be on reducing
      costs and improving service. Its principal business activities involve
      the provision of new connections, construction and refurbishment of the
      system, maintenance and fault repair, setting tariffs and collecting
      revenues for the use of its authorized networks, and all metering
      activities, from provision and repair to meter reading. Power Systems
      continues to focus strongly on the efficient delivery of electricity to
      customers in its franchise areas via its overhead and underground
      network. Investment in the business, has included significant upgrades
      and refurbishments to the transmission and distribution system.

      Power Systems is divided into three regions in Scotland, three regions
      in the Manweb authorized area and a metering business which covers both
      areas. It has a distribution/transmission network which extends to
      approximately 113,000 kilometers, with 63,000 kilometers of underground
      cables and some 50,000 kilometers of overhead lines.

     /1/Full-time equivalent

      ScottishPower and Manweb each hold a PES license allowing each company
      to undertake electricity distribution activities within its authorized
      area. The income derived from the distribution business is dependent on
      changes in the demand for electricity by customers in the franchise
      area. Demand for electricity is affected by such factors as growth and
      movements in population, social trends, economic and business growth or
      decline, changes in the mix of energy sources used by customers,
      weather conditions and energy efficiency measures. The following tables
      set out, by customer type, the levels of electricity distributed in GWh
      over ScottishPower and Manweb's distribution systems during the five
      most recent fiscal years.

      The group is committed to providing its customers with an electricity
      supply which is safe and reliable. Both ScottishPower and Manweb are
      fully compliant with the EU standards for safe and reliable electricity
      set forth in the European Standard EN50169 entitled "Voltage
      Characteristics of Electricity Supplied by Public Distribution
      Systems".

      In 1995, the Office of Electricity Regulation ("OFFER") made the
      provision of customer connections to the electrical network
      competitive. This change, together with similar actions by the Office
      of Gas Supply and the Office of Telecommunications, has provided an
      opportunity for the group to provide multi-utility connections, a
      development which provides benefits both to the group and to customers.
      The group has now developed fully integrated, cost effective packages,
      providing solutions for inward investors and property developers. Thus,
      the group has unrivalled expertise in delivering multi-utility projects
      ranging from large scale industrial sites to multi-unit commercial and
      housing developments.

      In late December 1998 and early January 1999, the group's network in
      Scotland sustained damage due to very severe weather conditions,
      causing interruptions to supply. ScottishPower is implementing measures
      to further improve its ability to deal with such incidents and is
      contributing to a review by OFFER of electricity companies' responses
      to the bad weather.

      Energy Supply
      The group's Energy Supply business ("Energy Supply") is responsible for
      the sales and marketing of electricity, gas and related products to
      customers within ScottishPower's and Manweb's respective home areas and
      to the competitive market throughout the rest of Great Britain. At the
      end of fiscal 1999, Energy Supply had 3.2 million electricity customers
      in Great Britain and an overall market share of 12%.

      Energy Supply's strategy is to defend the existing markets, build the
      energy customer base, and add value from an extended range of products
      and services--all underpinned by high-quality, low-cost service. In
      addition the group will continue to meet the electricity supply and
      service obligations of Scottish Power and Manweb under their respective
      PES licenses. The tables below set forth the relative proportion of
      units of electricity supplied by ScottishPower and Manweb to their
      residential, commercial and industrial customers over the five most

      Electricity Trading
      Electricity trading, within the Energy Trading Center, secures
      competitive advantage for the group through being an informed trader
      optimizing its position across the electricity value chain and
      continuously evaluating and managing trading risk exposure. The risks
      identified in electricity trading generally relate to price volatility
      arising in the Pool market in England and Wales and the group's overall
      exposure as a net generator (seller) or net supplier (purchaser) of
      electricity which can (and does) vary over time. Such net exposure can
      be managed through trading in contracts for differences with willing
      parties such as other generators, suppliers or intermediaries. As an
      external member of the Pool of England and Wales since 1990,
      ScottishPower has traded principally as an exporter (generator), in
      that energy market.

      Electricity Markets
      Energy Supply purchases electricity from a range of sources, including
      the group's generation business, for sale to customers both within its
      home areas and outside them. Until September 1998, only public
      electricity suppliers were entitled to supply customers in their
      franchise areas (now home areas) with demand less than 100 kW. From
      September 1998 to May 1999, the franchise areas of all public
      electricity suppliers were opened to competition on a phased basis,
      with the result that electricity suppliers holding second tier
      licenses, including ScottishPower and Manweb, are able to supply
      electricity to all customers in the franchise area of a public
      electricity supplier. Large industrial or commercial customers with
      demand above that threshold have been and continue to be able to seek
      supply from other electricity suppliers holding a "second tier"
      license. ScottishPower's and Manweb's respective franchises were opened
      to competition in three phases, commencing in September 1998 and
      running through to February 1999. Since September 1998, the strategic
      focus of the energy supply business has been defense of its existing
      markets, particularly domestic and small business customers in the
      ScottishPower and Manweb areas, while exploiting the opportunity to
      expand its customer base outside these regional boundaries. As at March
      31, 1999, the energy supply business had retained 96% of domestic
      customers in the ScottishPower area and 94% in Manweb. The business had
      also signed up 190,000 electricity contracts outside those home areas.

      In the highly competitive industrial and commercial energy market the
      group has sought to defend market share and has retained 76% of these
      volumes in the ScottishPower area. In Manweb, which comprises some of
      the largest industrial electricity users in the country, the group has
      retained a 27% share of these volumes. Outside the group's home areas,
      the group currently supplies around 1,750 GWh of electricity.

      As the industrial and commercial energy market has become increasingly
      commoditised, the group has continued to develop a presence in the
      growing energy services marketplace, focusing mainly on larger
      businesses. This involves the outsourcing of energy and utility related
      services for on-site generating plant, boiler and steam raising plant
      and other energy efficient applications.

      Gas Markets
      The group has a growing gas supply business, which exploits the
      synergies with the generation business and allows value to be created
      by profiling gas between supply and generation. The domestic gas supply
      market has been open to full competition (i.e., extended to premises
      with consumption under 2,500 therms per annum) since late May 1998. The
      group has now established itself as one of the leading challengers to
      Centrica plc (British Gas Trading) in this market, having already
      acquired a total of 760,000 domestic contracts at the end of fiscal
      1999, approximately 4.0% of the total U.K. gas supply market.

      In the business market, the group has continued to grow, supplying gas
      representing approximately 220 million therms per annum to 23,215 sites
      across the U.K.

      Domestic Energy Contracts
      Fiscal 1999 was a very challenging one for the group's energy
      businesses as the residential electricity supply market was opened to
      competition. At March 31, 1999, new domestic energy contracts secured
      since, in the case of gas, the second phase of competition in April
      1997 and, in the case of electricity, the introduction of competition
      in September 1998, totaled 950,000 (760,000 gas and 190,000 new
      electricity contracts). The group's focus is on securing "dual fuel"
      electricity and gas customers and to date the group has more than
      317,000 dual fuel energy contracts signed. The group's progress has
      been achieved in spite of intense competition. Electricity customers

      registered to leave the group at March 31, 1999 were 147,000,
      representing 5% of customers in ScottishPower's and Manweb's home
      areas.

      The group will continue to seek to win further new customers.
      Attracting new customers leads to initial costs in sales and marketing,
      information systems and new procedures. However, ScottishPower believes
      that this investment should contribute to earnings in the medium to
      longer term.

      Customer Service
      ScottishPower has taken steps to improve all aspects of its customer
      service within the energy businesses in preparation for full
      competition in the domestic electricity supply market, and intends to
      continue to treat improving customer service as a priority over the
      next year. The businesses' customer service guaranteed standards were
      maintained in the year ended March 31, 1999 at the high level set in
      the previous year, with over 99.99% of all electricity services
      provided currently matching or exceeding regulatory standards.

      All service requirements in Scotland are met by a customer service call
      center, employing modern communications and information technology,
      offering a comprehensive service to customers, including 24 hour faults
      and emergency support. In Manweb's home area the group has focused its
      activities on improving customer service through the provision of two
      regional call centers and a business call center. The group has also
      established a gas call center in Warrington servicing domestic and
      small business customers.

      The performance of ScottishPower and Manweb in the area of Guaranteed
      Standards failures over the last seven years as reported to OFFER is
      shown below.

      Domestic gas suppliers faced increases in complaints during the period
      of market liberalization. The most common complaints to the Gas
      Consumers' Council have concerned the change of supplier process and
      sales and marketing activity. ScottishPower received 2,285 OFGAS and
      Gas Consumer Council complaints during fiscal 1999, which equates to
      less than 1% of the customer accounts won during the year.
      ScottishPower's performance in terms of user complaints was
      considerably better than that experienced by some other market
      entrants.

      ScottishPower is responding to competition by reducing operating costs
      and improving customer service. Underlying operating costs within
      ScottishPower's home area have declined by an average of 10% per annum
      over the last three years. ScottishPower has achieved these reductions
      by consolidating customer service operations from nine regional offices
      into one Customer Service Call Center; introducing new customer systems
      to streamline processes and remove unnecessary manual effort;
      introducing more flexible working practices which enabled services to
      be expanded at minimum cost. These initiatives have enabled
      ScottishPower to match its resources to work profile more efficiently
      and to remove "back office" costs. In addition, following the Manweb
      acquisition in 1995, the group has continued to exploit opportunities
      for synergy savings in common or shared supply functions.

      Southern Water

      Structure of the Water Industry in the United Kingdom
      Prior to privatization of the water industry, the provision of water
      supply and wastewater services in England and Wales was split between
      twenty-nine statutory water companies, each incorporated by separate
      Acts of Parliament

ScottishPower Form 20-F 1999                                                  21

      which could only supply water, and ten water authorities established
      under the Water Act 1973 which could provide both water and wastewater
      services. Pursuant to the Water Act 1989 (the "WA 1989"), the functions
      of each water authority relating to water supply (except in areas where
      those functions were carried out through statutory water companies) and
      the provision of wastewater services were transferred on September 1,
      1989 to a Water and Sewerage Company (a "WaSC"). At privatization,
      certain of the water authorities' other functions, including pollution
      control, water resource management, fisheries, flood protection and
      alleviation and land drainage were transferred to the National Rivers
      Authority (the "NRA"). See "Environmental Regulation--Water" for
      further discussion.

      The relevant provisions of the WA 1989 were consolidated with other
      functional legislative provisions into the Water Industry Act of 1991
      ("WIA 1991"). This provides that each company engaged in public water
      supply or wastewater services must be licensed by the Secretary of
      State for the Environment or by the Director General of Water Services
      (the "DGWS"), in accordance with a general authorization given by the
      Secretary of State for the Environment. See "Regulation of the Water
      Industry".

      Southern Water was acquired by ScottishPower on August 6, 1996. At the
      time of its acquisition, Southern Water consisted of the holding
      company, an appointed WaSC (Southern Water Services), and a diverse
      portfolio of 20 other businesses.

      Region
      The region in which Southern Water operates occupies an area of
      approximately 10,450 square kilometers in the counties of Kent, East
      and West Sussex, Hampshire and the Isle of Wight and small parts of
      Wiltshire, Berkshire and Surrey. The region's coastline stretches from
      Swanscombe on the Thames Estuary to just beyond the Solent at Barton on
      Sea, including the Isle of Wight. The region has an estimated
      population of approximately 4.2 million. Around half of the resident
      population of the region live in urban areas spread along the coastline
      and around major estuaries. Approximately one fifth live in
      predominantly inland urban areas and the remainder inhabit
      predominantly rural areas. The portion of the region to which Southern
      Water supplies water covers a total area of some 4,450 square
      kilometers, contains approximately 1.0 million premises and has a
      resident population of some 2.2 million people. Local water companies
      supply the rest of the region's water requirements. Southern Water
      provides wastewater services to virtually all of the region, collecting
      sewage from around 1.7 million premises.

      Water Supply Business
      Southern Water supplies on average 600 million liters of water per day
      which is distributed through 13,300 kilometers of water main. Southern
      Water's 104 water treatment works treat water from 132 water sources in
      the region with 70% of water supplied coming from underground sources.
      Water is pumped through the water mains by 413 pumping stations.
      Southern Water is also responsible for the operation and maintenance of
      four impounding reservoirs which have a total storage capacity of
      42,390 million liters.

      Water put into supply exhibits a pronounced seasonal variation between
      summer and winter. Typically the peak seven day demand in the summer is
      up to 40% higher than the annual average and stems from increased
      residential usage and the influx of tourists to resort towns along the
      south coast and on the Isle of Wight.

      The bulk of Southern Water's underground sources are located in chalk,
      with a small number of abstractions being made from sandstone aquifers.
      The water is of high quality and receives various forms of treatment
      appropriate to each source. These provide reductions in the level of
      pesticides, iron and manganese; the reduction of plumbosolvency; and in
      all cases protection against bacteria throughout the distribution
      system to the point of use at the customers' taps by a residual level
      of chlorine. A single source has treatment to reduce the amount of
      nitrates, which is kept elsewhere within acceptable limits by blending
      output from various sources where necessary.

      The smaller proportion of water from rivers and reservoirs has a more
      complex form of treatment. In addition to the processes used for
      underground supplies, clarification and filtration processes provide a
      similar high quality drinking water. Again, in all cases disinfection
      is maintained by a residual level of chlorine.

      Southern Water has 13,300 kilometers of water main. In order to
      minimize the loss of water through leakage, a leakage control
      initiative was introduced following privatization in 1989 and has
      reduced water loss by 144 million

22                                                  ScottishPower Form 20-F 1999

      liters per day. Since privatization Southern Water has one of the best
      records with respect to water supply leakage among the WaSCs. Losses
      through leaks in its distribution system stand at 11.2% in fiscal 1999
      compared to 26% just before the time of privatization, with a target to
      achieve 11.0% by the year 2000.

      Southern Water monitors water quality through a program in which
      samples are analyzed regularly for both microbiological and chemical
      parameters. In 1998, 99.82% of water sampled passed the EU performance
      criteria.

      Wastewater Business
      Southern Water has 392 wastewater treatment works ("WTWs") which treat
      sewage pumped through 20,700 kilometers of sewer by 1,975 pumping
      stations. WTWs provide various treatment types as follows: primary,
      enhanced primary, secondary biological and tertiary. In addition, as
      part of the treatment process to meet current bathing water standards,
      Southern Water has 24 long sea outfalls around the coastline of its
      region.

      Under the Water Resources Act 1991, WTWs are granted consent by the
      Environment Agency (the "EA") to discharge sewage effluent to
      controlled waters. The conditions attached to each consent can cover
      quality, quantity and operational parameters as laid down in the
      "Standard Clauses" of the Discharge Consents Manual issued by the EA.
      The basis of the EA's policy is to maintain and improve water quality
      and the aquatic environment.

      In addition to the residential population, the businesses in Southern
      Water's region discharge industrial effluent having the equivalent
      strength of an additional population of about 486,000.

      The disposal of sludge produced by WTWs is strictly controlled.
      Disposal to landfill is becoming restricted due to the lack of
      available local sites. In addition, all sludge disposed in this way is
      subject to a Landfill Tax. Disposal at sea ceased by December 1998. It
      is intended that the majority of the sludge produced at Southern
      Water's WTWs will be further processed to produce a soil conditioner
      which can be recycled and sold to the agricultural industry and any
      remaining amount will be incinerated. The recycling of treated sludge
      to agricultural land is controlled by an EU directive while
      incineration is controlled by licenses issued by the EA. The sludge
      produced by Southern Water's WTWs amounts to 77,500 tonnes of dry
      solids per year.

      In the 1999 bathing season, under the EU Bathing Water Directive, the
      EA is testing 79 beaches in the Southern Water region. Under the
      directive, the EA takes at least 20 samples during the bathing water
      season (May 1 to September 30) at each identified bathing beach and
      compliance is assessed on the basis of tests for bacteria. Additional
      tests are carried out for 19 physicochemical parameters in addition to
      the bacterial test and on two occasions during each season the bathing
      water is tested for the presence or absence of enteroviruses. Results
      may be published and posted by district councils on the beaches
      concerned. In the 1998 bathing season, only 2 beaches out of 77 failed
      the compliance tests. Capital schemes are in progress to reduce the
      likelihood of failures in future years.

      Table 1.10 below sets forth key information with respect to the
      Southern Water's activities in fiscal 1999.

      Business Objectives
      Following the acquisition, a new business strategy has been developed
      based on maximizing value for ScottishPower shareholders. Under this
      new strategy, the group is seeking to radically remodel Southern Water
      into one of the U.K.'s most efficient water and wastewater companies.
      This has involved shifting the focus firmly back to the core business
      where the group's key utilities skills of asset management, customer
      service and regulatory management are being exploited to deliver
      enhanced value. Non-strategic businesses have been sold and business
      processes have been substantially simplified by absorbing certain key
      activities from the enterprise businesses back into an expanded core
      business. At the same time, head office functions have been
      rationalized, with group functions being transferred to Scotland.
      Southern Water contributed more than (Pounds)21 million of additional
      operating profit, mainly from increased revenues and continued cost
      savings of (Pounds)10 million delivered by the acquisition transition
      plan during fiscal 1999.

      The business strategy is also aimed at building a proactive and co-
      operative relationship with the Office of Water Services ("OFWAT"),
      including the development of an output driven capital program which
      delivers all of the obligations included in fiscal 1996 to fiscal 2000
      price determination period at a reduced cost from the agreed funding
      level granted by OFWAT. The delivery of obligations at lower cost than
      assumed in the price determination will generate efficiencies that will
      initially add shareholder value and ultimately result in a more cost-
      efficient service to customers.

      Investment Program
      In common with other WaSCs, Southern Water is faced with a substantial
      investment program for the period for 1996 to 2000, estimated to be of
      some (Pounds)1.0 billion. This program is largely driven by the EU
      Bathing Water Directive, the Urban Waste Water Treatment Directive
      ("UWWTD"), a sludge strategy to deal with cessation of dumping at sea,
      the increase in the volume of sludge due to the UWWTD and the
      expectation of more stringent environmental constraints relating to
      sludge disposal on land.

      The program is dominated by the construction of 24 new WTWs as required
      by the EU Directives. In addition, there are required regulations set
      by OFWAT, the Drinking Water Inspectorate and the EA to maintain and
      improve the security and quality of service provided. These outputs
      include projects to address:

      . above and below ground asset maintenance;

      . water resources and security of water supply;

      . reduced leakage and improved water pressure;

      . drinking water quality;

      . removal of flooding risk; and

      . avoidance of storm overflows on combined sewers.

      Southern Water was granted implicit funding in the price determination
      via an allowed annual rate of return on the OFWAT estimate of
      investment of (Pounds)1.0 billion. Southern Water's investment program
      has therefore essentially been "funded" upfront. A key aspect of the
      group's business strategy is to seek to deliver all of the required
      regulatory outputs of the capital program as efficiently as possible.

      ScottishTelecom
      ScottishPower Telecommunications Limited ("ScottishTelecom"), a
      subsidiary of ScottishPower, provides competitive communication
      services. Organic growth, coupled with a focused acquisitions policy,
      has positioned ScottishTelecom strongly across the breadth of the
      communication business since its launch in 1994.

      ScottishTelecom now provides, under innovative tariff packages, a wide
      portfolio of communication services ranging from fixed voice, data and
      mobile telephony services to call center services, on-line information
      and Internet access.

      In February 1998 ScottishTelecom acquired Pinnacle Cellular and it
      acquired Demon Internet for (Pounds)66 million on May 1, 1998.
      ScottishTelecom's "Scotland On-Line" and "Prestel" operations combined
      with Demon Internet now have in excess of 275,000 customers.

<PAGE>

      The business moved into operating profit during fiscal 1998 and
      contributed (Pounds)10.3 million to the group's audited consolidated
      operating profits for fiscal year 1999. ScottishTelecom's current share
      of the overall Scottish telecommunications market in which it operates
      is still relatively small, but is increasing. The ScottishPower Board
      believes that revenue growth will come from carrying Demon Internet
      telecoms traffic following the installation of a network switch and
      supporting infrastructure which was completed at the beginning of
      February 1999.

      The development of the group has caused the Directors to review the
      future of ScottishTelecom. ScottishPower is currently evaluating the
      strategy of ScottishTelecom and the options available to maximize
      shareholder value from its investment in this business, in what is a
      rapidly changing and developing sector. This assessment includes a
      review of the services provided by ScottishTelecom, its funding needs
      and any consequential restructuring. The Directors expect to reach a
      decision during the year.

      Other Businesses

      Electrical Retailing
      ScottishPower's electrical retailing business sells electrical products
      through a chain of 183 outlets throughout the U.K. In addition to
      retail sales, the group's electrical retailing business provides
      servicing and repair facilities and delivery and connection facilities.

      ScottishPower's electrical retailing business is the third largest
      specialist retailer of electrical appliances in the U.K. It now has
      5.5% of the U.K. 'white goods' market and 4.0% of the U.K. "brown
      goods' market. Electrical white goods (including cookers, washing
      machines, refrigerators and small residential appliances) account for
      approximately 60% of total appliance sales. Brown goods (including
      televisions, stereo equipment, computers and camcorders) account for
      approximately 40% of appliance sales.

      The business has continued to gain market share through incrementally
      increasing the number of new stores and organic growth from existing
      stores. During fiscal 1999 it opened 10 new superstores, increasing
      selling space by 76,289 square feet.

      Contracting Services
      The group's contracting services business specializes in niche markets,
      including the installation and maintenance of high voltage equipment,
      residential heating (electrical and gas installations), street
      lighting, security and fire alarms, residential telephone connections,
      appliance and installation inspection and pre-planned maintenance, as
      well as instrumentation, mechanical and project management along with
      property and facilities management.

      Technology
      The group's Technology business combines a number of groups which
      specialize in different areas of engineering consultancy and science,
      including mechanical, electrical, civil engineering and environmental
      sciences. The range of work undertaken by the business is expansive and
      includes most categories of engineering consultancy from design and
      construction of buildings, plant and components, to the development of
      sophisticated control systems and monitoring devices.

      In addition to supporting ScottishPower's operational activities, the
      Technology business is closely involved in ScottishPower's capital
      investment program in its power stations, in the design and project
      management of new generation schemes such as combined cycle gas turbine
      plant and wind farms. The business also plays an important role in the
      refurbishment of the group's electrical retailing stores and the
      development of the telecommunications infrastructure.

      Information Systems
      The Information Systems Division is heavily involved in helping the
      group's other businesses prepare for energy supply liberalization. In
      fiscal 1999, expenditure on systems development throughout the group
      was (Pounds)51 million.

      The group has already made substantial progress towards achieving Year
      2000 compliance, investing (Pounds)20 million in fiscal 1999. In
      addition, it has achieved the IBM "e-business mark', a fast developing
      standard for electronic commerce.

      Year 2000
      Potential computer problems associated with the Year 2000 date change
      are an issue for users of computer systems throughout the world,
      including systems with embedded chips. ScottishPower is dependent on
      its own systems and on those of its key suppliers and customers. The
      Directors do not believe that ScottishPower faces greater risks from
      Year 2000 issues than other comparable utility companies in the U.K.

      ScottishPower established its group-wide Year 2000 program in 1997 to
      seek to manage the effects that Year 2000 issues may have on the
      group's operations. The methodology used builds on practices developed
      in conjunction with several user groups, including the Electricity
      Association (the trade association for electricity), U.K. Y2K Interest
      Group (the largest Year 2000 self-help group in the U.K.) and IMPACT (a
      confederation of many of the Top 100 companies in the U.K.). The scope
      of ScottishPower's program covers all aspects of the group's business.

      ScottishPower's approach concentrates on three main areas which are as
      follows:

      . working on and testing its own internal systems through gathering
        inventory, assessing criticality, prioritization and planning,
        testing and remediation;

      . understanding the Year 2000 readiness of its suppliers and major
        customers; and

      . modifying and developing contingency processes to reduce residual
        risk.

      The program focuses on IT systems, both corporate and desktop, non-IT
      systems (embedded chip systems) including process monitoring and
      control, business processes and business partners. ScottishPower is
      currently reviewing contingency plans, operational procedures, staffing
      issues and "worst case" scenarios. A Millenium Operating Regime is
      being implemented, and is particularly aimed at enhancing the group's
      state of readiness for the rollover period.

      Within each of ScottishPower's businesses, the Directors believe that
      scheduled remediation projects on the group's systems are well advanced
      with 89% of all critical projects substantially complete. The group is
      finalizing compliance work on its systems, and this work is planned to
      be completed well in advance of the end of 1999.

      ScottishPower's systems and operations are also dependent on products
      and services provided by others. Since autumn 1997, all orders and
      contracts placed by ScottishPower have included a Year 2000 clause
      requiring compliance to the BSI standard PD2000-1. As part of the
      supply chain management work undertaken, ScottishPower is assessing
      critical suppliers and customers for their Year 2000 compliance. The
      group has made an initial assessment of all its critical suppliers and
      will continue to monitor all of them during 1999. Interdependencies
      with other utilities are being reviewed through the U.K. Y2K Utilities
      Forum and other forums and one-to-one meetings. All other suppliers are
      being treated in accordance to the group's reliance on them. Where
      appropriate, alternative suppliers may be appointed.

      ScottishPower's Year 2000 program has been carried out using internal
      resources where possible, supplier resources where appropriate and
      specialist contractors where considered necessary. As at March 31,
      1999, the group has already spent approximately (Pounds)22 million on
      its Year 2000 program. The Directors estimate, based on the group's
      best estimates and, where appropriate, advice from specialist
      contractors, that the total cost to ScottishPower of the Year 2000
      program will be approximately (Pounds)30 million. This does not include
      the cost of certain capital investment programs which are being
      accelerated in order to seek to resolve the Year 2000 issues.

      The Directors believe that the group's work on its own systems and
      equipment and review of critical suppliers means that the group is
      taking all reasonable steps to minimize the risks associated with Year
      2000 issues. Based on the current state of knowledge on managing Year
      2000 issues and the Directors' best estimates, the Directors believe
      that, because of the anticipated short-term nature of any potential
      interruptions, it is unlikely that Year 2000 issues will have a
      material impact on the group's financial condition or operations.
      However, there can be no assurance that the steps taken by the group
      will successfully minimize vulnerabilities of its software and systems,
      or those of its suppliers, to the problems associated with the
      transition to the Year 2000, that disruptions to the group's business
      will not occur or that the costs associated with the advent of the Year
      2000 will not be greater than anticipated.

      Regulation of the Electricity Industry

      Introduction
      The U.K. electricity industry is regulated under the provisions of the
      Electricity Act 1989. The Electricity Act provided for the basis of the
      restructuring of the electricity supply industry ("ESI") in England and
      Wales and in Scotland in 1990, including the introduction of price
      regulation for transmission and distribution and competition in supply
      and generation.

      Regulation of the ESI
      The Electricity Act provides for the appointment of the DGES by the
      Secretary of State for Trade and Industry. The DGES holds office for
      renewable periods of five years and is the head of OFFER and its staff
      of administrators, economists and accountants.

      Under the Electricity Act, the Secretary of State and the DGES are
      required to exercise their respective functions in the manner best
      calculated to achieve various objectives including securing that all
      reasonable demands for electricity are satisfied; securing that license
      holders are able to finance the carrying on of the activities for which
      they are authorized by their licenses; and promoting competition in the
      generation and supply of electricity. Subject to these duties, the
      Secretary of State and the DGES have a number of other duties,
      including protecting the interests of consumers of electricity.

      The DGES exercises, concurrently with the Director General of Fair
      Trading, certain functions relating to monopoly situations in the
      generation, transmission, distribution or supply of electricity under
      the Fair Trading Act 1973 and certain functions relating to anti-
      competitive conduct under the Competition Act 1980. Under the
      Competition Act 1998, the DGES will continue to exercise functions
      concurrently with the Director General of Fair Trading.

      The Licensing Regime
      The Electricity Act prohibits the generation, transmission or supply of
      electricity to any premises unless authorized by a license or
      exemption. Licenses are granted for generation, transmission, public
      electricity supply by a PES and second tier supply.

      Under the electricity regime, England and Wales is divided into 12 PES
      franchise areas, and Scotland into two additional PES franchise areas,
      for the purposes of electricity supply and distribution.

      Each of the 14 PES licenses permits its holder to supply electricity to
      any premises within its authorized franchise area (first-tier license).
      Electricity suppliers which are not the PES license holder for that
      franchise area are known as second-tier suppliers and have second-tier
      supply licenses (second-tier license).

      Each PES licensee distributes electricity for second tier suppliers
      whose customers are within that PES licensee's authorized area, as well
      as for its own supply business. Charges for distribution are made to
      the PES licensee's own supply businesses or to second-tier suppliers as
      appropriate. Each PES license prohibits discrimination between its own
      supply business and other users of its distribution system.

      Each PES licensee is required, among other duties, to develop and
      maintain an efficient, coordinated and economical system of electricity
      and supply and to offer terms for connection to, and use of its
      distribution system on a non-discriminatory basis; in particular, a PES
      licensee may not discriminate in favor of its own first- or second-tier
      supply businesses.

      Each PES license requires the PES licensee to plan and develop its
      distribution system to a standard not less than that previously
      applicable within the nationalized electricity supply industry and to
      report annually to the DGES giving details of the performance of the
      licensee in maintaining distribution security and availability and
      quality of service during the previous financial year.

ScottishPower Form 20-F 1999                                                  27

      ScottishPower is licensed under the Electricity Act to generate
      electricity, transmit electricity within its authorized transmission
      area and distribute and supply electricity within its authorized supply
      area. This license (a "Composite License") regulates each of its
      generation, transmission, distribution and supply businesses and
      certain other related aspects of its activities. In addition, it has
      second-tier licenses which authorize it to supply electricity to
      customers located outside its authorized supply area.

      Manweb is licensed under the Electricity Act to distribute and supply
      electricity within its authorized supply area pursuant to its PES
      license. Manweb also holds three second tier licenses which authorize
      it to supply electricity to users located in the authorized areas of
      other PESs, in England and Wales, Scotland and Northern Ireland
      respectively.

      Prior to September 1998, PESs were the only suppliers authorized to
      supply electricity to franchise customers (being customers with a
      maximum demand of less than 0.1 MW) in their respective authorized
      areas. Starting from September 1998, each PES was, at the direction of
      the DGES, to open its franchise area progressively to competition from
      other suppliers holding second tier licenses. The scope of the second
      tier licenses was extended correspondingly at the direction of the
      DGES. This process was completed in May 1999.

      In addition, in order for a second tier license holder to supply a
      "designated customer" (being a domestic customer or a customer
      requiring less than 12,000 kWh per year) in the authorized area of a
      PES, the second tier license holder must issue a designated supply
      notice to OFFER, and have its codes of practice (statements of intent
      about how the supplier will interact with customers) approved by OFFER.

      Modification of Licenses
      The DGES is responsible for monitoring compliance with the conditions
      of licenses and, where necessary, enforcing them through procedures
      laid down in the Electricity Act. License conditions may be modified,
      either in accordance with the terms of the relevant licenses or in
      accordance with the procedures laid down in the Electricity Act.

      Under the Electricity Act, the DGES may modify a license condition with
      the agreement of the license holders after due notice, public
      consultation and consideration of any representations or objections. In
      the absence of agreement, the only means by which the DGES can secure a
      modification is following a modification reference to the Competition
      Commission and in the circumstances set out below. A modification
      reference requires the Competition Commission to investigate and report
      on whether matters specified in the reference relating to the
      generation, transmission or supply of electricity in pursuance of a
      license operate, or may be expected to operate, against the public
      interest and, if so, whether the adverse public interest effect of
      those factors could be remedied or prevented by modification of the
      conditions of the license. In determining whether any particular matter
      operates, or may be expected to operate, against the public interest,
      the Competition Commission is to have regard to the matters in relation
      to which duties are imposed on the Secretary of State and the DGES.

      If there is an adverse finding, the Competition Commission's report
      will state whether any adverse effects on the public interest could be
      remedied or prevented by modification of the license conditions. If the
      Competition Commission so concludes, the DGES must then make such
      modifications to the license as appear to him requisite for the purpose
      of remedying or preventing the adverse effects specified in the report,
      after giving due notice and consideration to any representations and
      objections. The Secretary of State has the power to veto any
      modification reference.

      Modifications to license conditions may also be made in consequence of
      a monopoly or merger reference under the Fair Trading Act 1973 or,
      until March 2000, a reference under the Competition Act 1980. At that
      date, the relevant provisions of the Competition Act 1980 will be
      repealed by the Competition Act 1998.

      ScottishPower's acquisition of Manweb in 1995 and Southern Water in
      1996 involved ScottishPower giving assurances to the Secretary of State
      to modify Manweb's PES license and ScottishPower's Composite License
      (and Southern Water Services' Water Appointment). These modifications
      are discussed in more detail below. See "Principal Conditions of
      ScottishPower's Composite License and Manweb's PES License" and
      "Principal Conditions of Southern Water Services' Appointment".

<PAGE>


      Term and Revocation of Licenses
      ScottishPower's Composite License continues until terminated by not
      less than 25 years' notice given by the Secretary of State on or after
      March 31, 2000. Manweb's PES license also continues until terminated by
      not less than 25 years' notice given by the Secretary of State on or
      after March 31, 2000.

      ScottishPower's and Manweb's second-tier licenses in relation to
      second-tier supply in England and Wales continue until terminated by
      not less than 25 years' notice given by the Secretary of State for
      Trade and Industry on or after November 19, 2000, and April 1, 2001,
      respectively. ScottishPower's second-tier license in relation to what
      was formerly Scottish Hydro-Electric plc's authorized supply area
      continues until terminated by not less than 25 years' notice given by
      the Secretary of State for Trade and Industry on or after March 31,
      2000. Manweb's second-tier license in relation to Scotland continues
      until terminated by not less than 25 years' notice given by the
      Secretary of State for Trade and Industry on or after July 1, 2004.

      Licenses under the Electricity Act may be revoked in certain
      circumstances specified in the licenses, such as the insolvency of the
      licensee or the licensee's failure to comply with an enforcement order
      made by the DGES. In addition, the Secretary of State for Trade and
      Industry may revoke each of ScottishPower's generation, transmission
      and PES licenses if ScottishPower ceases to carry on the activities
      authorized by the respective license.


      Principal Conditions of ScottishPower's Composite License and Manweb's
      PES License
      ScottishPower's Composite License and Manweb's PES License require
      ScottishPower and Manweb respectively to prepare and publish separate
      accounts, including on a current cost accounting basis, for each of
      ScottishPower's generation, transmission, distribution and supply
      businesses (first and second tier and wholesaling business) and
      Manweb's distribution and supply businesses.

      It is a further license requirement that none of ScottishPower's nor
      Manweb's businesses gives any cross-subsidy to, or receives any cross-
      subsidy from, any of ScottishPower's or Manweb's other businesses,
      whether regulated by the Composite License or not.

      A number of Composite License and PES License conditions require
      ScottishPower and Manweb, respectively, to be party to certain
      agreements or codes which affect their operational activities, for
      example, the Grid Code, which includes provisions governing the
      technical aspects of connections to, and the operation of, the
      transmission systems. Each PES licensee must also draw up, implement
      and comply with a Distribution Code, which interacts with the Grid Code
      and specifies technical requirements for connection to, and the
      operation and use of, its distribution system, and Codes of Practice on
      customer relations, which require the approval of the DGES. There are
      also Electricity Supply Regulations and certain performance standards
      determined by the DGES which must be complied with.

      The modifications made upon the acquisition of Manweb were designed to
      address the fact that, as a result of the acquisition, Manweb became a
      subsidiary of ScottishPower. Broadly, the modifications were designed
      to ring-fence Manweb's regulated businesses (distribution, supply and
      second-tier supply) from its non-regulated businesses and from
      ScottishPower's other businesses, to impose certain information
      reporting requirements on Manweb and ScottishPower to assist the DGES
      in his ability to carry out his regulatory functions and to address the
      fact that ScottishPower and Manweb are both electricity companies.

      As a condition for regulatory clearance of ScottishPower's acquisition
      of Southern Water, ScottishPower gave assurances to the Secretary of
      State that it would not operate any new business which is not regulated
      under the Electricity Act and whose annual turnover accounts for more
      than 5% of ScottishPower's aggregate annual turnover excluding all
      subsidiaries, other than as subsidiary company; ensure that
      ScottishPower had sufficient management and financial resources to
      fulfill its obligations to enable the introduction of competition in
      supply for all customers in its authorized area; and agree to
      appropriate modifications to Southern Water's license. These are
      discussed in more detail below--see "Principal Conditions of Southern
      Water Services' Appointment".

      Price Controls
      The primary objective of the regulation of the U.K. electricity
      industry is the promotion of competition wherever possible while
      ensuring that demand can be met and companies are able to finance their
      regulated activities. However, it is recognized that the development of
      competitive markets is not appropriate in some areas (such as in the
      transmission and distribution of electricity) and that in other areas
      it will take time to develop (as in the supply of electricity). In
      these areas regulatory controls are deemed necessary to protect
      customers in a monopoly market (by determining inflation limited price
      caps) and to encourage efficiency.

      ScottishPower and Manweb's businesses are subject to a number of price
      controls which take the form of a maximum price which can be charged
      (price cap). This price cap restricts the average amount charged for a
      bundle of services. Since 1995 regulation has tended to restrict price
      increases to customers to levels below the increase in the retail price
      index through a formula expressed as RPI-X.

      The rationale behind the use of the RPI-X formula is that companies are
      motivated, during the period of the price control, to maximize
      efficiencies knowing that they can retain any element of
      overperformance for their shareholders. The price caps are expressed in
      terms of an RPI minus X constraint on charges, where RPI represents the
      annual percentage change in the U.K.'s retail price index, and X may be
      any number determined by the DGES. The X factor is used to reflect
      expected efficiency gains and investment requirements. For example,
      where RPI is running at 3% and X is 2%, a company would be able to
      increase the average charge for a bundle of services by 1%. Since the
      controls are forward looking and are based on forecasts (e.g.,
      projected electricity sales volumes), correction factors may also be
      required to adjust tariffs in subsequent years to account for any
      forecasting errors.

      The DGES from time to time reviews the price cap formulae applicable to
      the transmission, distribution and supply businesses to ensure that
      reasonable demands for electricity are satisfied, that license holders
      are able to finance the carrying on of their licensed activities
      (including the ability to raise capital at reasonable rates), that
      competition is promoted in the area of energy supply and that the
      interests of consumers of electricity are protected.

      ScottishPower and Manweb participate in reviews of price caps
      applicable to them by submitting to OFFER their view of what reasonable
      efficiency gains and future investment requirements should be built
      into the determination of the revised price control.

      As with any modification to license conditions, the DGES must undertake
      a consultation exercise, inviting comments from PES licensees and third
      parties, before modifying licenses to incorporate new price controls.
      As described above under "--The Licensing Regime--Modification of
      Licenses", license conditions may be modified, either with the consent
      of the licensee or, in the absence of consent, following a modification
      reference to the Competition Commission. The Competition Commission is
      an independent body whose statutory duty is to determine whether the
      matters specified in a reference to it operate or may be expected to
      operate, against the public interest, and if so whether the adverse
      public interest effect of those factors could be remedied or prevented
      by modification of the conditions of the license. The Competition
      Commission must have regard to the matters in relating to which duties
      are imposed on the Secretary of State and the DGES, but will also take
      evidence from the electricity companies and third parties before
      reaching its conclusion. If the Competition Commission concludes that
      adverse effects on the public interest could be remedied or prevented
      by modification of the license conditions, the DGES must then make such
      modifications to the license as to appear to him to be requisite to
      remedy or prevent the adverse effects identified.

      Through participation in, and the submission of evidence to, these
      price control reviews and, where necessary, through the Competition
      Commission modification process described above, companies have the
      opportunity to comment on and seek to influence the final outcome of
      any price control review.

      ScottishPower Transmission Price Control
      The permitted maximum average charge per unit transmitted calculated
      under the transmission formula, multiplied by a pre-determined number
      of units transmitted, including both in area consumption and exports,
      determines the maximum transmission revenue that ScottishPower is
      permitted to earn in any financial year from these services.

<PAGE>


      In September 1993, the DGES announced a revised transmission price
      control for ScottishPower, to take effect from April 1, 1994 and to run
      for five years. The new control left the X factor unchanged at RPI
      minus 1. The major changes to the initial control were: the inclusion
      of Interconnector revenue from the link with NGC within the definition
      of regulated revenue; the use of a predetermined forecast of units
      transmitted (including units transmitted onto another transmission
      system) rather than actual numbers transmitted; and the replacement of
      forecasts of inflation with actual historic values.

      In Spring 1998 ScottishPower agreed with the DGES to a delay of one
      year in the ScottishPower transmission price review with the new price
      control taking effect from April 1, 2000. For the interim year, fiscal
      2000, transmission revenue will be allowed to increase at the rate of
      inflation. OFFER is currently reviewing the scope and duration of the
      transmission price controls for Scotland thereafter and is expected to
      publish draft proposals for revised price controls in August 1999 and
      final proposals in November 1999, which will come into effect in April
      2000.

      Distribution Price Control
      The maximum distribution revenue is calculated from a formula that is
      based on customer numbers as well as units distributed. The current
      value of X for ScottishPower's distribution price control is 2 and will
      continue at this level until March 31, 2000. Following a reopening by
      the DGES in March 1995 of the five year price control set for RECs in
      England and Wales in August 1994 (and due to take effect on April 1,
      1995), the DGES imposed a one-off price reduction of 11% for Manweb
      from April 1, 1996. The value of X from April 1, 1997 to March 31, 2000
      was increased in England and Wales to 3.

      OFFER is currently reviewing the distribution price controls for all
      PESs and is expected to publish draft proposals in August 1999 and
      final proposals in November 1999, to come into effect in April 2000.

      Supply Price Control
      The value of X for ScottishPower's supply price control from April 1,
      1995 to March 31, 1998 was set at 2. The value of X for Manweb's supply
      price control from April 1, 1994 to March 31, 1998 was also set at 2.

      All customers are now subject to competitive supply, although certain
      smaller customers remain protected: for a two-year period from April
      1998, the supply price control operates as a maximum price restraint on
      tariff increases for ScottishPower's and Manweb's designated customers.

      The nature and extent of possible restraints from April 1, 2000 are
      being reviewed at the same time as the distribution price controls. By
      way of protection of the consumer, PES license conditions prohibit
      discriminatory, onerous or predatory pricing in areas in which a PES
      has been determined dominant (currently in the PES's authorized area).

      Future Regulation
      The prices which the group's electricity businesses may charge
      customers in their respective authorized areas are controlled by a
      formula which is linked to the U.K. RPI. Reviews of the price controls
      governing the group's electricity supply activities took effect from
      April 1, 1998 with a further review from April 1, 2000. Reviews of the
      price controls governing the group's transmission activities and
      distribution activities and for the water business will take effect
      from April 1, 2000. The effect of the current price controls is
      illustrated under "Effect of Price Controls".

      In March 1998, the HM Government published a Green Paper "A Fair Deal
      for Consumers-Modernising the Framework for Utility Regulation". In
      July 1998, the HM Government published a summary of the response to its
      consultations and in October 1998 it published a further consultation
      paper which contains specific proposals. The main proposals are:

      . separate licensing of supply and distribution activities of the PESs
        with the licenses to be held by separate legal entities, though not
        necessarily in separate ownership; and

      . a new single, primary duty on utility regulators to protect the
        interests of consumers, wherever possible and appropriate through the
        promotion of effective competition.

      Further proposals to revise the regulation of the electricity industry
      were published by the HM Government and the DGES in 1998, the most
      important of which include the following:

      . the DGES published proposals in July 1998 to reform the trading
        arrangements in England and Wales along the lines of commodity
        markets and other energy markets. The DTI published an Energy White
        Paper in October 1998, supporting the DGES's proposals, and setting
        out its expectation that wholesale price falls of at least 10% in
        real terms, and possibly more, can be expected in the medium term. In
        November 1998 a framework document on implementation of the new
        trading arrangements was published by the DGES (encompassing the
        development of a balancing market, a short-term bilateral market and
        a related settlement system). A Development and Implementation
        Steering Group has been set up to develop the new trading
        arrangements with a target implementation date of fall 2000;

      . revision of Scottish trading arrangements from April 2000. OFFER
        issued a consultation paper on options for future Scottish trading
        arrangements in December 1998, inviting comments on the creation of
        either a single trading area in Scotland or unified UK-wide trading
        arrangements. Further papers are expected to be published in June and
        August 1999 with final proposals in November 1999; and

      . separation of the supply, distribution, generation and transmission
        activities of ScottishPower and Scottish & Southern into separate
        companies. In May 1998, the DGES published a consultation paper on
        the separation of the distribution and supply activities of PESs to
        facilitate competition. It also considered the interface between
        transmission and generation in Scotland. A further consultation paper
        was published by OFFER in November 1998 proposing alternative
        scenarios for operational separation. Following examination by
        consultants of the costs of separation, OFFER published a further
        paper in May 1999, proposing new arrangements for metering and new
        obligations on PESs to separate their distribution and supply
        activities. In addition, the operational separation of transmission
        from generation in Scotland is being considered as part of the
        reviews of the transmission price controls and Scottish trading
        arrangements. A likely outcome will be a requirement for separate
        licensed businesses within the same group to operate as separate
        legal entities. Detailed proposals are expected in August 1999.

      The timing of any potential legislation arising from these proposals
      has not been announced. Until then the group will be actively involved
      in the consultation process.

      Callum McCarthy has been appointed as combined energy regulator, taking
      up the post of Director General of Gas Supply in November 1998 and
      Director General of Electricity Supply in January 1999.

      Regulation of the Water Industry

      Introduction
      The U.K. Water Industry is principally regulated under the provisions
      of WIA 1991 and the Water Resources Act 1991. WIA 1991 consolidates
      enactments relating to the supply of water and the provision of
      wastewater services, including WA 1989 and other enactments. WA 1989
      provided for the privatization process itself and set up the post-
      privatization structure and regulation of the industry.

      WIA 1991
      WA 1989 (now WIA 1991) provided for the appointment by the Secretary of
      State for the Environment of an industry regulator, the DGWS. The DGWS
      holds office for renewable periods of five years and is the head of
      OFWAT and its staff of administrators, economists and accountants. The
      current DGWS, Ian Byatt, was appointed as the first DGWS on August 1,
      1989 and was subsequently re-appointed for a five-year term to run from
      June 30, 1996 to the end of June, 2000.

      The EA regulates discharges by water companies into rivers and coastal
      waters and the abstraction of water from rivers and ground water; and
      the Drinking Water Inspectorate regulates the quality of drinking water
      in accordance with EU standards.

<PAGE>

      Under WIA 1991, the DGWS and the Secretary of State for the Environment
      must exercise or perform their duties in the manner best calculated to
      secure that the functions of a water undertaker and of a sewerage
      undertaker are properly carried out as respects every area of England
      and Wales; and to ensure that companies holding Appointments are able
      (in particular, by securing reasonable returns on their capital) to
      finance the proper carrying out of their functions.

      These powers and duties are also to be exercised in a manner best
      calculated to ensure that the interests of the customer in relation to
      the fixing and the recovery of charges are protected, and in particular
      to ensure that the interests of customers and potential customers in
      rural areas are so protected; that no undue preference is shown; and
      that there is no undue discrimination in the fixing of those charges.

      The DGWS and the Secretary of State for the Environment are also under
      a duty to ensure that the interests of customers are protected as
      respects benefits that could be secured for them by applying a share of
      the proceeds of any disposals of a WaSC's land in future reviews.

      The DGWS exercises, concurrently with the Director General of Fair
      Trading, certain functions relating to monopoly situations in the
      supply of water or the provision of wastewater services under the Fair
      Trading Act 1973, and certain functions relating to anti-competitive
      conduct in connection with the supply of water or securing a supply of
      water or with the provision of, or securing of, wastewater services
      under the Competition Act 1980. Under the new U.K. competition
      legislation (Competition Act 1998), the DGWS will continue to exercise
      functions concurrently with the Director General of Fair Trading.

      Duties of Water Undertakers
      Under WIA 1991, each water undertaker is under a general duty to
      develop and maintain an efficient and economical system of water supply
      within its license area. It must also ensure that all such arrangements
      have been made for providing supplies of water to premises in its
      license area, for making such supplies available to people who demand
      them and for maintaining, improving and extending its mains and other
      pipes, as are necessary to enable it to meets its water supply
      obligations under the Act.

      Duties of Sewerage Undertakers
      Under WIA 1991, each sewerage undertaker is under a general duty to
      provide, improve and extend such a system of public sewers and to
      cleanse and maintain those sewers to ensure that its sewerage region is
      effectively drained. Sewerage undertakers are required to make
      provision for the emptying of sewers and whatever further arrangements
      are necessary from time to time for effectively dealing with the
      contents of sewers. In addition, discharges from wastewater treatment
      works must be consented to by the Environment Agency ("EA"); and
      sewerage undertakers are responsible under WIA 1991 for regulating
      discharges of industrial effluent into sewers. Contamination of
      controlled waters by non-complying effluent being discharged by a
      treatment works may involve the sewerage undertaker in liability,
      including clean-up costs.

      The Licensing Regime
      Following privatization of the U.K. water industry in 1989, each of the
      water and sewerage undertakers, while maintaining its effective
      monopoly supply, became regulated through an instrument of Appointment.
      The Appointment confirms the appointment of the water or sewerage
      undertaker as supplier in its own area and provides for the monitoring
      of its performance by the DGWS and the Secretary of State for the
      Environment.

      Modification of Licenses
      The DGWS is responsible for monitoring compliance with the conditions
      of Appointments and, where necessary, enforcing them through procedures
      laid down in WIA 1991. Conditions of the Appointment may be modified,
      either in accordance with the terms of the relevant licenses or in
      accordance with the procedures laid down in WIA 1991. Subject to a
      power of veto by the Secretary of State, the DGWS may modify the
      conditions in the Appointment with the consent of the licensee. Before
      making the modifications, the DGWS must publish the proposed
      modifications as part of a consultation process, giving third parties
      the opportunity to make representations and objections which the DGWS
      must consider.
ScottishPower Form 20-F 1999

                                                                              33
<PAGE>


      In the absence of consent, the only means by which the DGWS can secure
      a modification is following a modification reference to the Competition
      Commission and in the circumstances set out below. A modification
      reference requires the Competition Commission to investigate and report
      on whether matters specified in the reference relating to the carrying
      out of any function of a company by virtue of its Appointment operate,
      or may be expected to operate, against the public interest and, if so,
      whether the adverse public interest effect of those factors could be
      remedied or prevented by modification of the conditions of the
      Appointment. In determining whether any particular matter operates, or
      may be expected to operate, against the public interest, the
      Competition Commission is to have regard to the matters in relation to
      which duties are imposed on the Secretary of State for the Trade and
      Industry and the DGWS.

      If there is an adverse finding, the Competition Commission's report
      will state whether any adverse effects on the public interest could be
      remedied or prevented by modification of the license conditions. If the
      Competition Commission so concludes, the DGWS must then make such
      modifications to the Appointment as appear to him requisite for the
      purpose of remedying or preventing the adverse effects specified in the
      report, after giving due notice and consideration to any
      representations and objections. The Secretary of State for Trade and
      Industry has the power to veto any modification by agreement.

      Modifications to license conditions may also be made in consequence of
      a monopoly or merger reference under the Fair Trading Act 1973 or,
      until March 2000, a reference under the Competition Act 1980. At that
      date, the relevant provisions of the Competition Act 1980 will be
      repealed by the Competition Act 1998.

      Southern Water Services' Appointment was modified as a result of
      assurances given by ScottishPower as a condition to receiving
      regulatory clearance for its acquisition of Southern Water plc in 1996.
      These are discussed in more detail below, see "Principal Conditions of
      Southern Water Services' Appointment".

      Term and Revocation of Licenses
      Southern Water Services' Appointment continues until terminated by not
      less than 10 years' notice given to Southern Water Services by the
      Secretary of State for the Environment, expiring not earlier than 25
      years after September 1, 1989, the transfer date. Appointments may also
      be revoked or transferred to another company in certain circumstances
      specified in WIA 1991 or in the Appointments, such as the appointee
      failing to comply with an enforcement order made by the Secretary of
      State for the Environment or the DGWS, or the appointee being unable to
      pay its debts.

      Principal Conditions of Southern Water Services' Appointment
      The principal regulatory provisions which apply to the regulated
      activities of Southern Water Services are set out in WIA 1991 and
      regulations and orders made under it. Other business activities of
      Southern Water, such as waste management and other environmental
      services, engineering services and systems technology services, if
      undertaken, fall outside the direct scope of regulation under WIA 1991.
      Southern Water Services is an appointed WaSC and holds an Appointment
      regulated under WIA 1991 to supply water and sewerage services within
      its authorized area, which regulates its appointed activities. Southern
      Water Services' Appointment requires Southern Water Services to prepare
      and publish separate accounts, including on a current cost accounting
      basis showing separately its appointed business from all other
      businesses and activities. It is a further Appointment requirement that
      the regulated business neither gives to, nor receives from, any other
      business or activity of Southern Water Services, any cross-subsidy,
      whether those businesses are regulated by the Appointment or not.

      Southern Water Services' Appointment was modified following assurances
      given to the Secretary of State for Trade and Industry by ScottishPower
      as a condition to regulatory clearance of its acquisition of Southern
      Water plc to address regulatory concerns arising out of the merger, in
      particular to ensure the management independence of Southern Water
      Services and strengthen the ring fencing of its finances.

      As a result, the Appointment of Southern Water Services contains an
      obligation that it must at all times conduct the businesses regulated
      by its Appointment as if such businesses were substantially Southern
      Water Services' sole business and Southern Water Services were a
      separate public listed company. In particular, Southern Water Services
      must ensure that its board of directors is independent of ScottishPower
      and includes two non-executive

34                                                  ScottishPower Form 20-F 1999
<PAGE>

      Directors of relevant experience and standing. All Directors must
      disclose to Southern Water Services and to the DGWS any conflicts with
      their duties as Directors of Southern Water Services and have regard
      exclusively to the interests of Southern Water Service as a water and
      sewage undertaker, in the event of a potential conflict with the
      interests of other group companies. The DGWS must be informed of any
      change in the identity and functions of the Directors of Southern Water
      Services.

      In addition, Southern Water Services must not, without the consent of
      the DGWS make a loan to or guarantee any liability of any group
      company, or make any disposal of any asset of the regulated business.
      The payment of dividends by Southern Water Services should not impair
      its ability to finance its regulated business. Similarly, any financial
      support or transfer of assets from Southern Water Services to a group
      company must not adversely affect the former's ability to carry out its
      functions.

      In March 1998, Southern Water issued a (Pounds)100 million variable
      rate bond to help fund capital expenditure. The bond listing provides a
      form of Stock Exchange listing for the water business, to compensate
      OFWAT for the loss of comparative information (as a result of the
      discontinuance of Southern Water's stock exchange listing on the
      acquisition by ScottishPower). The bond listing imposes an obligation
      on Southern Water Services to comply with financial information
      requirements incumbent on a quoted plc and to maintain an investment
      grade rating for all its corporate debt.

      As a condition for regulatory clearance of ScottishPower's acquisition
      of Southern Water, ScottishPower gave assurances to the Secretary of
      State that it would not operate any new business which is not regulated
      under the Electricity Act and whose annual turnover accounts for more
      than 5% of ScottishPower's aggregate annual turnover excluding all
      subsidiaries, other than as a subsidiary company; ensure that
      ScottishPower had sufficient management and financial resources to
      fulfil its obligations to enable the introduction of competition in
      supply for all customers in its authorized area; and agree to
      appropriate modifications to Southern Water's license.

      Price Controls
      Southern Water Services' business is subject to price controls.
      Southern Water Services is allowed to increase its standard charges for
      the provision of water supply and sewerage services by the percentage
      change in the RPI plus an adjustment factor K. The value of K is
      currently set at 4% for the period ending on March 31, 2000. In 1996,
      as a result of the takeover of Southern Water Services by
      ScottishPower, ScottishPower undertook that the average price increases
      of Southern Water Services in the three charging years commencing April
      1, 1997, would be lower than the allowed charging limits. This
      undertaking was the subject of a license condition modification which
      came into effect on September 28, 1996, requiring Southern Water
      Services' average prices to be 1% lower than they would otherwise have
      been in 1997 and 3% lower than they would otherwise have been in the
      two years from April 1998.

      Infrastructure charges, being the amount that Southern Water Services
      can charge when new properties are connected for a domestic supply of
      water or sewerage services for each service, are also controlled. The
      infrastructure charge was set at (Pounds)200 for 1995-96 and is
      permitted to rise in line with inflation in subsequent charging years.

      The DGWS reviews Southern Water Services' price controls on a five year
      basis. The DGWS also has the power to make an interim determination to
      adjust price limits between the five yearly periodic reviews. At
      present, price limits for the water and sewerage companies are being
      examined as part of such a periodic review to be concluded in November
      1999, when the DGWS will set new price limits for the period from April
      1, 2000 to March 31, 2005. In setting price limits, the DGWS proposes
      to take into account compliance with environmental and quality
      standards in assessing price limits for the period from 2000 to 2005.
      The DGWS will also consult each water company individually to discuss
      responses to the review. In July 1999, the DGWS will publish a draft
      determination of new price limits to run from 2000 to 2005, and final
      decisions will be made in November 1999. The outcome of this price
      review and its impact on the group is uncertain.

ScottishPower Form 20-F 1999                                                  35
<PAGE>


      As part of the current review process, on October 29, 1998 the DGWS
      published a consultation paper setting out proposed ranges for bills
      for the period from 2000 to 2005. In this paper, the DGWS has confirmed
      that, on the basis of past efficiencies achieved by water companies, he
      considers there to be scope for substantial price reductions in April
      2000. However, HM Government has proposed a program of capital
      expenditure by the water companies aimed at environmental improvements
      which was included in the consultation paper. This program is estimated
      to cost some (Pounds)8.5 billion in the aggregate. The water companies
      would be entitled to pass that cost through to customers with the
      effect of increasing bills in the four years after 2000. In the
      consultation paper, the DGWS estimated, in the case of Southern Water
      Services, that expected average household bills could be reduced by
      more than 17.5% (in real terms) in 2000/01 on previous year levels.
      However, the DGWS expected there to be an overall increase in the
      1999/2000 level of bills in the four year period up to 2005.

      ScottishPower has responded to the DGWS's proposals by requesting an
      initial price increase of 3.5% and a K factor of + 3% which would
      result in an average regulated rate of return of 6.5%.

      Large industrial users can now choose their own water and sewerage
      suppliers. From April 1, 2000 fifteen water companies including
      Southern Water, will not be able to recoup from other customers any
      amounts lost by offering lower tariffs to such industrial users. The
      regulated charging base to which price limits apply will no longer
      include tariffs to large industrial users. Southern Water Services
      agreed to this change to its Appointment in February 1999.

      Future Regulation
      In May 1997, it was reported that the Secretary of State for the
      Environment announced a review by the Department of the Environment to
      examine ways in which environmentally damaging abstractions can be
      equitably curtailed. The review will also include arrangements for
      revoking licenses in areas where pumping causes significant
      environmental damage. The consultation paper was published on June 19,
      1998 and was open for comment until September 17, 1998. The review is
      still progressing and it is unlikely that legislation will be
      introduced before the 2000/01 Parliamentary session.

      Effect of Price Controls
      It is expected that regulation will continue to have a material bearing
      on the profitability and investment capability of ScottishPower.
      ScottishPower's regulated monopoly businesses comprise electricity
      transmission and distribution in ScottishPower and electricity
      distribution in Manweb (together representing 44% of the 1999 operating
      profit) and the water supply and wastewater business in Southern Water
      (representing 30% of ScottishPower's 1999 operating profit). The
      regulatory price controls relating to these areas of ScottishPower's
      business for the five year period commencing April 1, 2000 are
      currently being reviewed by regulatory authorities in the U.K., as well
      as those relating to supply and generation. ScottishPower believes that
      it has high standards of operation and customer service. Nevertheless,
      ScottishPower is unable to judge accurately the outcome of these
      reviews and there can be no assurance that they will not materially
      affect profits. It is expected that all the results of these reviews
      will be known by November 1999.

      The natural monopoly businesses of the group which are currently
      subject to RPI-X price controls in the electricity businesses and RPI +
      K for Southern Water Services had a combined total turnover of
      (Pounds)1,156.2 million in fiscal 1999, or approximately 25% of group
      total turnover of (Pounds)4,706.0 million. However, these businesses
      had a combined operating profit of (Pounds)595.4 million in fiscal
      1999, or some 74% of the group's total operating profit of
      (Pounds)802.8 million. The breakdown of total turnover and operating
      profit among the natural monopoly businesses of the group is shown in
      the table below:

<PAGE>


      As an example of the effect of an RPI-X price control, the current
      transmission price control applicable to ScottishPower was set at RPI-1
      to take effect from April 1, 1994 and to run for five years. Had this
      control been set at RPI-2 for the same period, then the allowed revenue
      for fiscal 1999 would have been 5% lower than the value of
      (Pounds)136.8 million above, because of the cumulative effect of the
      control. All other things being equal, this would have resulted in a
      reduction of operating profit of some (Pounds)6.8 million. A similar
      effect would occur with the other price controls dependent on when the
      control had been set. For a five year control a tightening of X or K by
      1 percentage point would result in average annual allowed revenue over
      the five year period being reduced by 2.5% which, all other things
      being equal, would be around (Pounds)29 million in total for the four
      regulated businesses above.

      Each price control is subject to a separate price review undertaken by
      the applicable regulator and the setting of a new price control
      requires the license to be amended. If ScottishPower, or any of its
      subsidiaries, does not agree with the new price control then it is up
      to the company to seek a referral to the Competition Commission. Under
      such a reference the Competition Commission would be required to
      investigate and report on whether the revenues generated under the
      control would be sufficient for ScottishPower to finance its activities
      covered by the control.

      While it is only in these natural monopoly businesses that price
      controls (RPI-X and RPI+K) will continue for the foreseeable future, a
      supply price restraint will continue for a period of two years from
      April 1, 1998. The Supply price restraint takes the form of maximum
      tariff levels applying to individual tariffs, or groups of tariffs.
      These levels were set to give a reduction of 4.1% in real terms from
      April 1, 1998 with a further reduction of 3% in real terms from April
      1, 1999. This is an interim measure and the form of constraint is one
      setting maximum tariff levels for the two years. The nature and extent
      of possible restraints from April 1, 2000 will be reviewed in light of
      the experience and prospects at the same time as the distribution price
      controls are reviewed.

      The Competition Act 1998
      The U.K. has enacted new legislation, the Competition Act 1998, which
      introduces in the U.K. law prohibitions on anti-competitive agreements
      and the abuse of a dominant position. The Competition Act 1998 replaced
      the Monopolies and Mergers Commission with a new statutory body to be
      known as the Competition Commission with effect from April 1, 1999. The
      Competition Act 1998 also provides the Office of Fair Trading with
      significant investigative powers and the ability to grant interim
      measures.

      The Competition Act 1998 will grant the DGES and the DGWS concurrent
      powers with the Director General of Fair Trading in relation to,
      respectively "commercial activities connected with the generation,
      transmission, or supply of electricity" and "commercial activities
      connected with the supply (or securing a supply) of water or of
      sewerage services".

      Environmental Regulation
      The group's businesses are subject to numerous regulatory requirements
      with respect to the protection of the environment, including
      environmental laws which regulate the construction, operation and
      decommissioning of power stations, pursuant to legislation implementing
      environmental directives adopted by the EU and protocols agreed under
      the auspices of international bodies such as the United Nations
      Economic Commission for Europe ("UNECE").

      Electricity Generation, Transmission and Supply
      The Electricity Act obligates the Secretary of State 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. This Electricity Act requires the group to take into
      account the conservation of natural features of beauty and other items
      of particular interest, when it formulates proposals for development in
      connection with certain of its activities. The group is required, in
      terms of the Environmental Impact Assessment Regulations, 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. The group also prepares formal statements on
      the "Preservation of Amenity and Fisheries' in line with the
      requirements of the Electricity Act.

      Possible adverse health effects of electric and magnetic fields
      ("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 can cause adverse health effects. This uncertainty has
      been reinforced by a number of recent studies and as a result a number
      of claims which were being brought against other companies within the
      electricity business in the U.K. alleging personal injuries caused by
      EMFs have been dropped.

      The Environmental Protection Act of 1990 (the "EPA") requires that
      potentially polluting activities such as the operation of combustion
      processes (which includes power plant) requires prior authorization.
      These authorizations dictate the control technologies and techniques to
      be used to ensure that environmental harm is prevented or minimized.
      The Act also provides for the licensing of waste management and imposes
      certain obligations and duties on companies which produce, handle and
      dispose of waste. Waste generated as a result of the group's
      electricity activities is managed to ensure compliance with legislation
      and waste minimization is undertaken where possible.

      Environmental Regulation of Generation Activities
      The EPA is the primary U.K. statute governing the environmental
      regulation of power stations. It introduced a system of Integrated
      Pollution Control ("IPC") in April 1991 for large scale industrial
      processes, including power stations. Under the EPA, the authority for
      enforcing IPC with respect to emissions to atmosphere in England and
      Wales is the EA, previously Her Majesty's Inspectorate of Pollution
      ("HMIP"), and in Scotland is the Scottish Environment Protection Agency
      ("SEPA"), previously Her Majesty's Industrial Pollution Inspectorate
      ("HMIPI"). Transfer of control from HMIP and HMIPI to EA and SEPA came
      into force on April 1, 1996 and was established by the Environment Act
      of 1995 (the "1995 Act").

      The EU has adopted a framework directive on ambient air quality
      assessment and management which came fully into force in May 1998 (the
      "EU Directive on Integrated Pollution Prevention and Control"). The
      directive defines and fixes objectives for air quality, while
      subsidiary directives establish emission limit values for a number of
      contaminants. The EU Directive on Integrated Pollution Prevention and
      Control is being implemented via modifications to the IPC regime.

      The United Nations Framework Convention on Climate Change sets forth
      standards regarding emissions of greenhouse gases, the most significant
      of which is carbon dioxide (CO\\2\\). Agreement on a Protocol under
      this convention was reached in Kyoto in December 1997. This Protocol,
      when ratified, calls for mandatory target reductions of "a basket" of
      six greenhouse gases, most significantly CO\\2\\, in the commitment
      period 2008-2012. The Protocol also provides for Joint Implementation
      ("JI") between signatories, a Clean Development Mechanism by which
      signatories may gain credit for actions in certain non-signatory
      countries and a provision which would allow for trading of emissions.

      The EU has, under the terms of the Kyoto Protocol, signed up to the
      United Nations Framework Convention on Climate Change, under which
      Member States are committed to reducing "greenhouse gases" by 8% below
      1990 emission levels between the years 2008 and 2012. This reduction
      target applies to the EU as a whole, with each individual Member State
      being allocated its own target which is 12.5% for the U.K. HM
      Government has announced its intention of unilaterally setting itself a
      goal of 20% reduction in carbon dioxide emissions by 2010. The UNECE
      protocols regarding sulphur dioxide (SO\\2\\) and oxides of nitrogen
      (NOx) are currently implemented in the EU by means of the Air Framework
      Directive and Large Combustion Plants Directive (the "LCPD"). Emissions
      limits for existing and new plants will be introduced via the LCPD, the
      Air Framework Directive and, in the future, the EU Directive on
      Integrated Pollution Prevention and Control.

      The principal emissions from fossil fuelled electricity generation are
      SO\\2\\, NOx, CO\\2\\ and particulate matter, such as dust, with the
      main waste being ash, namely pulverized fuel ash and furnace bottom
      ash. The primary focus of current environmental legislation is to
      reduce emissions of SO\\2\\, NOx and particulates, the first two of
      which contribute to acid rain. A number of other power station
      emissions and discharges are subject to environmental regulation.

38                                                  ScottishPower Form 20-F 1999
<PAGE>

      Under the requirements of the LCPD, HM Government has implemented a
      national program, the National Plan, to reduce SO\\2\\ and NOx
      emissions from power stations in Scotland. ScottishPower and Scottish &
      Southern have entered into an agreement providing for the sharing of
      limits in emissions of SO\\2\\ and NOx from existing generating
      stations in Scotland set out in the National Plan to meet the targets
      of the LCPD. It also provides for the sharing of station-specific
      limits on emissions of SO\\2\\ and NOx imposed by SEPA at the
      Peterhead, Longannet and Cockenzie generating stations where capacity
      is shared between ScottishPower and Scottish & Southern. Reductions of
      CO\\2\\, SO\\2\\ and NOx per unit of electricity generated have been
      achieved as a result of the group's investments in environmental
      upgrades, such as low NOx burners and gas reburn, to existing power
      stations and in new power stations, together with increases in the
      proportion of the group's output generated by more efficient coal-fired
      power stations. ScottishPower's emissions of SO\\2\\ and NOx have been
      below the limits set by the National Plan for these emissions each year
      since its publication.

      Each of ScottishPower's power stations is required to have IPC
      authorization. Under IPC, each power station has a single authorization
      which regulates emissions of certain pollutants and seeks to minimize
      pollution of the environment. Each IPC authorization requires that a
      power station uses the Best Available Techniques Not Entailing
      Excessive Cost ("BATNEEC") to prevent the emissions described above or,
      to the extent this is not practicable, to minimize and render harmless
      any such emissions. Each authorization also contains an improvement
      program. ScottishPower's IPC authorizations do not have an expiry date,
      but SEPA is required to review the conditions contained within it at
      least once every four years and may impose new conditions to prevent or
      reduce emissions of pollutants, subject to the application of BATNEEC.
      The EU Directive on Integrated Pollution Prevention and Control
      requires that all emission and pollution control measures be placed
      upon the best available technique to control impact on the environment.

      The IPC authorizations granted in 1993 in respect of ScottishPower's
      existing power stations limit the levels of atmospheric emissions of
      SO\\2\\ and NOx from each station. A number of minor variations have
      taken place with a full four year IPC review now underway with SEPA.
      The review commenced in April 1997. Due to continued UK-wide policy
      development on the control of SO\\2\\, the review has continued into
      1999. The final outcome is awaited. The group is confident that it will
      be able to achieve the environmental improvements required by potential
      future limits arising from this review without materially constraining
      operational and commercial flexibility. In particular, gas reburn
      technology offers greater potential to reduce emissions than other
      technology in use elsewhere in the U.K. Furthermore, planning consent
      has been gained for flue gas desulphurization at Longannet, which will
      be installed when emissions levels require its implementation.

      Water
      Since April 1, 1996, the EA has been responsible in England and Wales
      for the control of water pollution and the maintenance and improvement
      of the quality of controlled waters, including the regulation of
      discharges to those waters; for conserving, redistributing and
      augmenting water resources and for securing the proper use of such
      resources for land drainage and flood defense. Previously, this was the
      responsibility of the NRA in England and Wales. In Scotland, SEPA has
      largely replaced the River Purification Boards to fulfil these
      responsibilities. The group is also subject to regulations governing
      drinking water quality, receiving water quality and wastewater
      discharges. Although recent cases have suggested that commercial
      enterprises may be fined more heavily for pollution offenses than in
      the past, ScottishPower does not believe that the level of fines will
      have a materially adverse impact on its operations.

      Within its general water resource management role, the EA has a duty to
      operate the system under the Water Resources Act 1991, whereby water
      undertakers and other abstractors must have a license authorizing each
      of their abstractions and other impoundments. It also has a duty to
      enter into water resource management arrangements with water
      undertakers to secure the proper management and operation of waters,
      reservoirs and other works vested in the undertakers. The EA may, and
      shall if so directed, consider the setting of minimum acceptable flows
      in rivers and make recommendations to the Secretary of State
      accordingly.

      Under the Water Resources Act 1991 and the Control of Pollution Act
      (COPA) 1974, the EA may require persons to take precautions against
      pollution, may prohibit or restrict certain activities likely to cause
      pollution in areas designated by the Secretary of State, and may impose
      a requirement for a consent to discharge matter from a drain or sewer.
      When reviewing existing consents and issuing new ones, the EA has said
      that it will seek to set contamination which causes, or is likely to
      cause, significant harm to the environment or any pollution of

ScottishPower Form 20-F 1999                                                  39
<PAGE>

      conditions at the level required to at least maintain and, where
      appropriate, improve the quality of the receiving waters.

      HM Government's upgrading of minimum levels of wastewater treatment for
      coastal works will mean further improvements to recently completed new
      works such as Eastbourne and Shoreham, as well as a review of proposed
      treatment levels in several long-term investment projects at Dover and
      Folkestone, Littlehampton and Bognor, Margate and Broadstairs, and the
      Isle of Wight.

      Under the EPA, the EA is responsible for maintaining registers
      containing details of applications for discharge consents, consents
      granted and the results of samples of effluent and receiving waters.
      The registers are open to public inspection.

      European Legislation
      The activities of the WaSCs are affected by the requirements of EU
      directives including the Drinking Water Directive, the Bathing Waters
      Directive and the Urban Waste Water Treatment Directive. EU directives
      are binding on HM Government, not on the Water Service Companies, as to
      the result to be achieved within a specified period. It is the
      responsibility of European Member States, including the U.K., to bring
      into force appropriate national environmental legislation, such as the
      Urban Waste Water Treatment Regulations to implement these EU
      directives.

      New requirements will be binding on the Water Service Companies only
      when they are translated into the law of England and Wales. Any
      expenditure incurred by a Water Service company necessitated by new
      legislation applying to them in their capacity as water or sewerage
      undertakers, or by any change in consents as a result of any changes to
      existing EU directives, or adoption of future EU directives, would be
      eligible for consideration for a specific K adjustment.

      The Water Resources Act and the Urban Waste Water Treatment Regulations
      are the main U.K. statutes governing water abstraction, receiving water
      quality and wastewater discharges. This legislation implements the
      Bathing Waters Directive and the Urban Waste Water Treatment Directive
      and requires improvements in the treatment of wastewater discharges.
      The Water Supply (Water Quality) Regulations introduce the requirements
      of the EU Drinking Water Directive into the U.K. and govern drinking
      water quality. In fiscal 1999, Southern Water spent approximately
      (Pounds)179 million to comply with the relevant statutes. Fines
      received by Southern Water in fiscal 1999 for violating water quality
      standards and the terms of applicable discharge consents were
      immaterial to the results of operations of Southern Water.

      Southern Water, like other WaSCs in the U.K., must have a license from
      the EA authorizing each of its abstractions and certain impoundments.
      For additional obligations of Southern Water affecting the environment,
      see the sections of this document entitled "Water Business--Southern
      Water" and "Regulation of the Water Industry".

      In addition to its other obligations affecting the environment,
      Southern Water may be required by the EA to take precautions against
      pollution, may be prohibited or restricted by the EA from certain
      activities likely to cause pollution in areas designated by the
      Secretary of State, and may be required by the EA to obtain a consent
      to discharge matter (other than sewage or trade effluent) from a drain
      or sewer. Further, in the course of its activities, the EA may carry
      out anti-pollution works and may recover the cost of such works from
      the person responsible for the pollution.

      General
      While the nature of developments in environmental regulation and
      control cannot be predicted, the group anticipates that the direction
      of future changes will be towards tightening controls. In view of the
      age and history of many sites owned by the group, the group may incur
      liability in respect of sites which are found to be contaminated,
      together with increased costs of managing or cleaning up such sites.
      Site values could be affected and potential liability and clean-up
      costs may make disposal of potentially contaminated sites more
      difficult. The Environment Act 1995 (the "1995 Act") requires the
      polluter (or if the polluter cannot be found or has legally transferred
      its responsibilities by disclosure, the owner or occupant) of
      contaminated land to clean up any

40                                                  ScottishPower Form 20-F 1999


<PAGE>

      controlled waters, so that environmental compliance is consistent with
      the intended use of the site. Although there have been prolonged
      consultations, the U.K. Government has yet to bring forward finalized
      regulations to implement the appropriate sections of the 1995 Act but
      is expected to do so during 1999. Other proposals which may impose
      strict liability for environmental damage are also under consideration
      by the EU. ScottishPower is not currently aware of any liability which
      it may have under the 1995 Act or of proposed EU directives which will
      have a materially adverse impact on its operations.

      The group believes that it has taken and continues to take measures to
      comply with applicable laws and regulations for the protection of the
      environment.

      Research & Development
      The group supports research into development of the generation,
      transmission, distribution and supply of electricity and continually
      seeks more innovative and cost effective methods of carrying out its
      water and wastewater activities. It also continues to contribute, on an
      industry-wide basis, towards the cost of research into electricity
      utilization, distribution developments and water purification and
      wastewater treatment. In fiscal years 1997, 1998, and 1999 the group's
      expenditure on research and development was (Pounds)5.6 million,
      (Pounds)5.4 million and (Pounds)5.3 million, respectively.

      Employees
      The group had 15,145 full-time equivalent employees as of March 31,
      1999. A breakdown of the number of full-time equivalent employees
      employed in the group's main businesses over the last five years is
      illustrated in the following table.

      Approximately 45% of group employees are union members and 66% are
      covered by collective bargaining arrangements. These reductions by
      comparison with previous years largely reflect manpower growth within
      ScottishTelecom where union strength is generally low. There are a
      number of different collective agreements now in place throughout the
      group reflecting differing market conditions in which the group's
      businesses operate. Management believes its overall relations with its
      employees are good.

      In the energy businesses, ongoing integration of Scottish and Manweb
      operations has been largely completed. The group continues to benchmark
      for further efficiencies and reduced costs which will include ongoing
      reduction in manpower numbers. However, these reductions have been
      offset in fiscal 1999 by manpower growth within customer-facing
      businesses to gain new customers in the fully deregulated market place.

      Within Southern Water, manpower reductions have occurred and will
      continue as the business is reorganized to focus on core activities,
      achieving operating improvements and taking better advantage of
      technological advancements. Manpower reductions of approximately 20%
      are anticipated over the next two years.

      The manpower figure in ScottishTelecom has increased by 63% in fiscal
      1999 from fiscal 1998 due to significant growth, both organic and
      inorganic, and in particular the group's acquisition of Demon Internet
      in 1998. This growth is expected to continue in fiscal 2000.

      The other businesses which include electrical retailing, electrical
      contracting, engineering consultancy, information systems and corporate
      services have remained relatively stable in manpower numbers since
      fiscal 1998.

      Item 2. Description of Property

      The group's properties consist of generating stations, transmission and
      distribution facilities, water supply and wastewater treatment
      facilities, telecommunication facilities, retail facilities and certain
      non-operational properties in which the group holds freehold or
      leasehold interests. The group believes that substantially all of its
      facilities are in a condition adequate for their purpose and
      utilization according to the individual nature and requirements of
      relevant operations. The group has a continuing program of improvements
      and maintenance of properties when considered appropriate to meet the
      needs of the individual operations. In connection with any of the
      group's properties that are held under lease, the group believes that
      it will be able to negotiate lease renewals on satisfactory terms or
      relocate the relevant facilities without such relocation having a
      material adverse impact on the group or its operations.

      Generation Facilities
      The group owns eight power stations in Scotland, six of which are
      operational with a total net output capacity of 4,035 MW, and one in
      England. The group also owns three windfarms in Northern Ireland, one
      in Scotland and one in the Republic of Ireland. In addition, the
      company has joint venture interests in three windfarms, two of which
      are in England and one in Wales. All generation plant is owned by the
      group, with the exception of the Methil power station, which is held on
      a ground lease which expires in 2012 and the windfarms which are
      generally held on ground leases of at least 25 years duration. Further
      details regarding the generating capacity of ScottishPower's power
      stations and windfarms as of March 31, 1999 are contained under "Item
      1. Description of Business--Energy Business--Generation Wholesale".

      Transmission and Distribution Facilities
      As of March 31, 1999, the group's transmission facilities included
      approximately 4,000 circuit kms of overhead lines and 240 circuit kms
      of underground cable operated at 400 kV, 275 kV and 132 kV.

      In addition, as of March 31, 1999, the group's distribution facilities
      included approximately 24,000 circuit kms of overhead lines and 40,000
      circuit kms of underground cable operated at 33 kV, 11 kV, and 0.4/0.23
      kV in Scotland and approximately 20,000km of overhead lines and
      23,000km of underground cable operating at 132 kV, 25 kV, 11 kV, 6.6
      kV, 6.3 kV, and 0.4/0.23 kV in England and Wales. The group holds
      either permanent rights or wayleaves which entitles it to run these
      lines and cables through private land. Wayleaves are usually terminable
      by either the landowner or the group upon six or twelve months' notice.
      The group has statutory rights to seek the compulsory retention of a
      wayleave if termination is sought by the landowner. The group owns the
      land for in excess of 95% of the transmission substation sites.
      Approximately 64% of the distribution substation sites are owned by the
      group with the remainder being secured by wayleave lease or local
      agreement. Approximately 25% of the leases securing substation sites
      expire within five years.

      Water Supply and Wastewater Treatment Facilities
      Southern Water has freehold and leasehold interest covering a total of
      approximately 10,000 acres of land. Of such land, an aggregate of
      approximately 9,800 acres are specialized properties, consisting
      chiefly of the raw water storage reservoirs with surrounding land,
      water and wastewater treatment works and pumping stations listed below.
      Approximately 95% of the above-ground water supply and wastewater
      assets are on land in Southern Water's freehold ownership including the
      assets listed below, with the remainder being located on land subject
      to long-leasehold.

      Telecommunication Facilities
      As of March 31, 1999, ScottishTelecom operated a network comprising
      approximately 2,550 km of optical fiber cable. Installation of the
      fiber is subject to wayleaves under the Public Telecommunications
      Operator License held by ScottishTelecom. The majority of
      ScottishTelecom's telecommunication network switching and transmission
      equipment is located in four main operational sites in Glasgow, London,
      Edinburgh, and Warrington. Additional telecommunication network
      equipment is housed in equipment rooms under the control of the group.

      Retail Facilities
      As of March 31, 1999, the group operated 183 retail outlets, 24 of
      which are owned by the group and 159 are leased. The outlets are
      located both on the main street of major metropolitan areas and in out
      of town superstores. The group also leases two large retail
      distribution depots, one at Castleford in England consisting of
      approximately 8,000 square meters; and another facility of
      approximately 12,600 square meters at Mossend near Glasgow. The
      properties are generally held on leases of 20 to 25 years.

      Non-Operational Facilities
      In addition to the properties described above, as of March 31, 1999,
      the group utilized a number of non-operational properties comprised
      primarily of offices, depots, warehouses and workshops. Approximately
      50% of these properties are owned by the group with the remainder being
      leased. The most significant of these non-operational properties are
      Cathcart Business Park, Glasgow (which is the main office for the
      electricity businesses in Scotland), the corporate office located at
      Atlantic Quay, Glasgow, the Manweb head office at Manweb House, Chester
      Business Park and the Southern Water head office at Worthing.

      Item 3. Legal Proceedings

      Manweb participates in the industry-wide Electricity Supply Pension
      Scheme. Two other members of the scheme, National Power plc and NGC,
      have been the subject of legal proceedings in connection with the use
      of surplus following an actuarial valuation at March 31, 1992 to fund
      early retirement benefits. Manweb also applied surplus following that
      valuation and the subsequent valuation at March 31, 1995 ((Pounds)6
      million following the 1992 valuation and (Pounds)32 million following
      the 1995 valuation) for the same purpose.

      In a decision on February 10, 1999, the Court of Appeal decided that,
      without a scheme amendment or trustee agreement, employers could not
      apply surplus unilaterally to forgive an accrued liability. This could
      lead to employers being required to make additional contributions to
      the scheme to meet that liability. A further hearing took place in May
      1999 which clarified certain aspects of the judgment. The judgment
      indicates that Manweb may be liable for additional contribution to the
      scheme. Leave to appeal to the House of Lords was given and if an
      appeal is made, it is unlikely to be heard before mid-2000.

      There is a range of possible outcomes to the current NGC litigation,
      any of which could affect Manweb's own potential liability, if any, to
      contribute to the scheme. If amendments can be made to the scheme to
      perfect the past arrangements to use surplus, no employer contributions
      should be required. If the courts in the NGC case ultimately decide
      that additional payments are due from employers to the scheme in
      respect of all or any part of the surplus used since the 1992
      valuation, Manweb may also be required to make payments. However in
      this event two further points must be determined before the ultimate
      cost to Manweb could be assessed: the effective date for calculating
      the amounts due, and whether payments can be spread over a number of
      years. Both these issues may affect significantly the ultimate cost to
      Manweb.

      No proceedings have been commenced against Manweb as at June 30, 1999
      (being the latest practicable date prior to the publication of this
      document) in respect of the issues raised by the NGC decisions.

      Except as discussed above, ScottishPower is not aware of any material
      pending legal proceedings, other than ordinary routine litigation
      incidental to the business of the group, to which ScottishPower or any
      of its subsidiaries is a party, or of which any of their property is
      the subject, or any such proceedings known to be contemplated by any
      governmental authority.

      Item 4. Control of Registrant

      (a) As far as is known to ScottishPower, ScottishPower is not directly
          or indirectly owned or controlled by another corporation or by any
          foreign government.

      (b)(i)   As of June 30, 1999, no person known to ScottishPower owned more
               than ten per cent of any class of the group's voting securities.

         (ii)  As of June 30, 1999, the total amount of voting securities
               owned by Directors and executive officers of ScottishPower as a
               group was:

      In addition, as of June 30, 1999, the Directors and executive officers
      of ScottishPower, as a group, held options to purchase 900,559 ordinary
      shares, all of which options were issued pursuant to ScottishPower's
      Long Term Incentive Plan, ScottishPower's Executive Share Option Scheme
      or ScottishPower's Sharesave Scheme. See "Item 12. Options to Purchase
      Securities From Registrant or Subsidiaries" and Note 33 to the
      Consolidated Financial Statements of the group.

      (c) ScottishPower does not know of any arrangements the operation of
          which might result in a change in control of the group.

      Item 5. Nature of Trading Market

      The principal trading market for the ordinary shares of ScottishPower
      is the London Stock Exchange. In addition, American Depositary Shares
      ("ADSs") (each of which represents four ordinary shares) have been
      issued by The Bank of New York, as depositary (the "Depositary"), for
      the company's ADSs and are traded on the New York Stock Exchange
      following listing on September 8, 1997.

      The table below sets forth, for the calendar quarters of the fiscal
      years indicated, the highest and lowest middle market quotations for
      the ordinary shares, as derived from the Daily Official List of the
      London Stock Exchange and the range of high and low closing sale prices
      for ADSs, as reported over-the-counter prior to September 8, 1997 and
      as reported on the New York Exchange Composite Tape following that
      date.

        which took effect on the listing of the ADSs on the New York Stock
        Exchange on September 8, 1997. Until that time, each ADS represented ten
        ordinary shares.

      On March 31, 1999, there were 332 registered holders of 127,842
      ordinary shares with addresses in the United States and 13 registered
      holders of 1,221,487 ADSs (equivalent to 4,885,948 ordinary shares).
      The combined holdings of these shareholders constituted 0.42% of the
      total number of ordinary shares outstanding as of March 31, 1999. As
      certain of the ordinary shares and ADSs are held by brokers and other
      nominees, these numbers may not be representative of the actual number
      of beneficial owners in the United States or the number of ordinary
      shares or ADSs beneficially held by U.S. persons.

      Item 6. Exchange Controls and Other Limitations Affecting Security
               Holders

      (a) There are currently no U.K. laws, decrees or regulations that
          restrict the export or import of capital, including, but not
          limited to, foreign exchange capital restrictions, or that affect
          the remittance of dividends or other payments to non-U.K. resident
          holders of the company's securities except as otherwise set forth
          in "Item 7. Taxation" below.

      (b) There are no limitations imposed by U.K. law or the company's
          Memorandum and Articles of Association that restrict the right of
          non-U.K. resident or non-U.K. citizen owners to hold or vote the
          ordinary shares other than the restrictions described in "Item 14.

        filed with the U.S. Securities and Exchange Commission in September
        1997 and incorporated herein by reference. However, non-U.K.
        shareholders are not entitled to receive notices from the company,
        including notices of general meetings, unless they have given the
        company an address in the U.K. to which such notices may be sent.

      Item 7. Taxation

      The following discussion of U.K. and U.S. federal income tax
      consequences is set forth with respect to U.S. tax considerations in
      reliance upon the advice of Milbank, Tweed, Hadley & McCloy LLP,
      special U.S. counsel to the company, and with respect to U.K. tax
      considerations in reliance upon the advice of the company's internal
      taxation adviser. The discussion is intended only as a summary of the
      principal U.S. federal income tax and U.K. tax consequences to
      investors who hold the ADSs or ordinary shares as capital assets and
      does not purport to be a complete analysis or listing of all potential
      tax consequences of the purchase, ownership and disposition of ADSs or
      ordinary shares. The summary does not discuss special tax rules that
      may be applicable to certain classes of investors, including banks,
      insurance companies, tax exempt entities, dealers, traders who elect to
      mark to market, investors with a functional currency other than the
      U.S. dollar, persons who hold the ADSs as part of a hedge, straddle or
      conversion transaction, or holders of 10% or more of the voting stock
      of the company. The statements of U.K. and U.S. tax laws and practices
      set out below are based on the laws in force and as interpreted by the
      relevant taxation authorities as of the date of this report. The
      statements are subject to any changes occurring after that date in U.K.
      or U.S. law or practice, in the interpretation thereof by the relevant
      taxation authorities, or in any double taxation convention between the
      United States and the United Kingdom. The company believes, and the
      discussion therefore assumes, that it is not a passive foreign
      investment company for United States federal income tax purposes.

      Each investor is urged to consult its own tax adviser regarding the tax
      consequences of the purchase, ownership and disposition of ordinary
      shares or ADSs under the laws of the United States, the United Kingdom
      and their constituent jurisdictions and any other jurisdiction where
      the investor may be subject to tax.

      If the obligations contemplated by the Deposit Agreement are performed
      in accordance with its terms, a beneficial owner of ADSs will be
      treated as the owner of the underlying ordinary shares for the purposes
      of the current convention between the United States and the United
      Kingdom for the avoidance of double taxation with respect to taxes on
      income and capital gains (the "Income Tax Convention") and for the
      purposes of the U.S. Internal Revenue Code of 1986, as amended (the
      "Code").

      For the purposes of this summary, the term "U.S. Holder" means a
      beneficial owner of the ADSs that is a United States citizen or
      resident, a domestic corporation or partnership, a trust subject to the
      control of a U.S. person and the primary supervision of a U.S. court,
      or an estate the income of which is subject to United States federal
      income tax regardless of its source.

      For the purposes of this summary, the term "Eligible U.S. Holder" means
      a U.S. Holder that is a resident of the United States for the purposes
      of the Income Tax Convention and that satisfies the following
      conditions:

      (i)   is not also resident in the United Kingdom for U.K. tax purposes;

      (ii)  is not a corporation which, alone or together with one or more
            associated corporations, controls, directly or indirectly, 10% or
            more of the voting stock of the company;

      (iii) whose holding of the ADSs is not effectively connected with a
            permanent establishment in the United Kingdom through which such
            holder carries on a business or with a fixed base in the United
            Kingdom from which such holder performs independent personal
            services, and;

      (iv) under certain circumstances, is not a company 25% or more of the
           capital of which is owned, directly or indirectly, by persons that
           are neither individual residents of, nor nationals of, the United
           States.

      Taxation of Dividends
      Individuals and companies who are resident in the United Kingdom and
      who receive the dividend on the ordinary shares are entitled to a tax
      credit (the "associated U.K. tax credit"). Under the Income Tax
      Convention and under current U.K. law, an Eligible U.S. Holder is
      entitled to receive, in addition to the dividend paid, an amount equal
      to the associated U.K. tax credit, subject to a U.K. withholding tax
      equal to 15% of the sum of the dividend and the associated U.K. tax
      credit. Beginning April 6, 1999, the rate of the associated U.K. tax
      credits for dividends is 1/9 of the dividend (i.e. the equivalent of
      10% of the sum of the dividend and the associated tax credit). As a
      result, Eligible U.S. Holders generally will not receive additional
      payments in respect of associated U.K. tax credits. Instead, payments
      to Eligible U.S. Holders will be reduced by the excess of the U.K.
      withholding tax over the associated U.K. tax credit.

      If ScottishPower paid a dividend of $90, for example, for U.S. federal
      income tax purposes an Eligible U.S. Holder would recognize ordinary
      income of $90 plus the $10 U.K tax credit, or a total of $100. The
      gross payment would be subject to a U.K. withholding tax of $10. The
      income is recognized when the dividend is actually or constructively
      received by the Eligible U.S. Holder, in the case of ordinary shares,
      or by the Depository, in the case of ADSs. The dividend will not be
      eligible for the dividends-received deduction generally allowed to
      United States corporations in respect of dividends received from other
      United States corporations. Distributions in excess of current and
      accumulated earnings and profits, as determined for United States
      federal income tax purposes, will be treated as a return of capital to
      the extent of the Eligible U.S. Holder's basis in the ordinary shares
      or ADSs and thereafter as capital gain. In determining the amount of
      dividend income, an Eligible U.S. Holder will use the spot currency
      exchange rate on the date the dividend is included in income. Any
      difference between that amount and the dollars actually received may
      constitute foreign currency gain or loss, which is ordinary gain or
      loss. Individual Eligible U.S. Holders, however, are not required to
      recognize gain of less than $200 from the exchange of foreign currency
      in a "personal transaction" as defined in Section 988(e) of the Code.

      Subject to certain limitations and requirements, an Eligible U.S.
      Holder will be entitled under the Income Tax Convention to credit the
      U.K. withholding tax against the Eligible U.S. Holder's United States
      federal income tax liability. Claiming a U.S. foreign tax credit with
      respect to the U.K. withholding tax imposed under the Income Tax
      Convention upon the refunded U.K. tax credit may result in a lower
      effective U.S. federal income tax rate on dividends paid by
      ScottishPower for certain Eligible U.S. Holders. It is not clear
      whether inclusion on the U.K tax credit in income and entitlement to
      the U.S. foreign tax credit are dependent on the Eligible U.S. Holder
      filing a claim with the U.K. Inland Revenue. Eligible U.S. Holders that
      do not elect to claim foreign tax credits may instead claim a deduction
      for U.K. withholding tax. For foreign tax credit limitation purposes,
      the dividend will be income from sources without the United States. The
      rules relating to the computation of foreign taxes are complex and
      Eligible U.S. Holders should consult their own tax advisors to
      determine whether and to what extent a credit would be available and
      whether any filings or other actions may be required to substantiate an
      Eligible U.S. Holder's foreign tax credit claim.

      If, at some point in the future, ScottishPower is at least 50% owned by
      United States persons, then under Section 904(g) of the Code, dividends
      paid by a foreign corporation that is at least 50% owned by United
      States persons may be treated as United States source income (rather
      than foreign source income) for foreign tax credit purposes to the
      extent the foreign corporation has more than an insignificant amount of
      United States source income, and the effect of this rule may be to
      treat a portion of the dividends paid by ScottishPower as United States
      source income. Under the Income Tax Convention, Section 904(g)(10) of
      the Code would permit an Eligible U.S. Holder to elect to treat
      ScottishPower dividends as foreign source income for foreign tax credit
      limitation purposes, if the dividend income is separated from other
      income items for purposes of calculating the holder's foreign tax
      credit.

      If the U.S. Holder is a U.S. partnership, trust or estate, the
      associated U.K. tax credit will be available only to the extent that
      the income derived by such partnership, trust or estate is subject to
      United States federal income tax as the income of a resident either in
      its hands or in the hands of its partners or beneficiaries, as the case
      may be.

      Whether holders of ADSs who reside in countries other than the United
      States are entitled to a tax credit in respect of dividends on ADSs
      depends in general upon the provisions of conventions or agreements, if
      any, as may exist between such countries and the United Kingdom.

      Taxation of Capital Gains
      In general, for U.S. tax purposes, U.S. Holders of ADSs will be treated
      as the owners of the underlying ordinary shares that are represented by
      such ADSs and deposits and withdrawals of ordinary shares by U.S.
      Holders in exchange for ADSs will not be treated as a sale or other
      disposition for U.S. federal income tax purposes.

      Upon a sale or other disposition of ordinary shares or ADSs, an
      Eligible U.S. Holder will recognize gain or loss for United States
      federal income tax purposes in an amount equal to the difference
      between the U.S. dollar value of the amount realized and the Eligible
      U.S. Holder's tax basis (determined in U.S. dollars) in such ordinary
      shares or ADSs. Generally, such gain or loss will be a long-term
      capital gain or loss if the Eligible U.S. Holder's holding period for
      such ordinary shares or ADSs exceeds one year any such gain and loss
      generally will be income from sources within the United States for
      foreign tax credit limitation purposes. Long-term capital gain for a
      non-corporate Eligible U.S. Holder is generally subject to a maximum
      tax rate of 20%.

      A U.S. Holder who is not resident or ordinarily resident for U.K. tax
      purposes in the United Kingdom will not be liable for U.K. tax on
      capital gains recognized on the sale or other disposition of ADSs,
      unless the ADS holder carries on a trade, profession or vocation in the
      United Kingdom through a branch or agency and the ADSs are or have been
      used, held or acquired for the purposes of such trade, profession or
      vocation or such branch or agency.

      U.S. citizens resident or ordinarily resident in the United Kingdom,
      U.S. corporations resident in the United Kingdom by reason of their
      business being managed or controlled in the United Kingdom and U.S.
      citizens who or U.S. corporations which, are trading or carrying on a
      trade, profession or vocation in the United Kingdom through a branch or
      agency and who or which have used, held or acquired the ADSs for the
      purposes of such trade, profession or vocation or such branch or agency
      may be liable for both U.K. and U.S. tax in respect of a gain on the
      disposal of the ADSs. Such holders may not be entitled to a tax credit
      against their United States federal income tax liability for the amount
      of U.K. capital gains tax or U.K. corporation tax on chargeable gains,
      as the case may be, paid in respect of such gain unless the holder
      appropriately can apply the credit against tax due on income from
      foreign sources.

      United States Information Reporting and Backup Withholding
      In general, information reporting requirements will apply to dividend
      payments (or other taxable distributions) in respect of ordinary shares
      or ADSs made within the United States to a non-corporate United States
      person. Accordingly, individual U.S. Holders will receive an annual
      statement showing the amount of taxable dividends paid to them during
      the year. "Backup withholding " at the rate of 31% will apply to such
      payments (i) if the holder or beneficial owner fails to provide an
      accurate taxpayer identification number in the manner required by
      United States law and applicable regulations, (ii) if there has been
      notification from the Internal Revenue Service of a failure by the
      holder or beneficial owner to report all interest or dividends required
      to be shown on its federal income tax returns or, (iii) in certain
      circumstances, if the holder or beneficial owner fails to comply with
      applicable certification requirements.

      In general, payment of the proceeds from the sale of ordinary shares or
      ADSs to or through a United States office of a broker is subject to
      both United States backup withholding and information reporting
      requirements, unless the holder or beneficial owner establishes an
      exemption. Different rules apply to payments made outside the United
      States through an office outside the United States.

      U.K. Inheritance Tax
      An individual who is domiciled in the United States for the purposes of
      the convention between the United States and the United Kingdom for the
      avoidance of double taxation with respect to estate and gift taxes (the
      "Estate Tax Convention") and who is not a national of the United
      Kingdom for the purposes of the Estate Tax Convention generally will
      not be subject to U.K. inheritance tax in respect of the ADSs on the
      individual's death or on a gift of the ADSs during the individual's
      lifetime, unless the ADSs are part of the business property of a
      permanent establishment of the individual in the United Kingdom or
      pertain to a fixed base in the United Kingdom of an individual who
      performs independent personal services. Special rules apply to ADSs
      held in trust. In the

48                                                 ScottishPower Form 20-F 1999


<PAGE>

      exceptional case where the shares are subject both to U.K. inheritance
      tax and to U.S. federal gift or estate tax, the Estate Tax Convention
      generally provides for the tax paid in the United Kingdom to be
      credited against tax paid in the United States.

      U.K. Stamp Duty and Stamp Duty Reserve Tax
      No U.K. stamp duty will be payable on the acquisition or transfer of
      ADSs provided that the instrument of transfer is executed outside the
      United Kingdom and subsequently remains at all times outside the United
      Kingdom. An agreement to transfer ADSs in the form of ADRs settled
      within or reported through any system approved under U.K. Treasury
      Regulations will give rise to a liability to stamp duty reserve tax at
      the rate of 0.5%. Transfers between non-residents not settled or
      reported through any system approved under U.K. Treasury regulations
      are exempt from stamp duty reserve tax.

      An agreement to purchase ordinary shares, as opposed to ADSs, will
      normally give rise to a charge to U.K. stamp duty or stamp duty reserve
      tax at the rate of 0.5% of the price. Stamp duty reserve tax is
      generally the liability of the purchaser and is usually paid by the
      purchaser. Where such ordinary shares are later transferred to the
      Depository's nominee, further stamp duty or stamp duty reserve tax will
      normally be payable at the rate of (Pounds)1.50 per (Pounds)100 (or
      part thereof) of the value of the ordinary shares at the time of the
      transfer. However, where ordinary shares being acquired are transferred
      directly to the Depositary's nominee, the only charge will generally be
      the higher charge of (Pounds)1.50 per (Pounds)100 (or part of the price
      payable for the ordinary shares so acquired) and the stamp duty reserve
      tax generally will not apply.

      Prior to April 6, 1999, a transfer of ordinary shares by the Depositary
      or its nominee to the relative ADS holder when the ADS holder is not
      transferring beneficial ownership gave rise to a U.K. stamp duty at the
      rate of 50p per transfer. On April 6, 1999, this rate increased to
      (Pounds)5 per transfer.

      Item 8. Selected Financial Data

      The selected financial data set out below are extracted or derived from
      the consolidated financial statements of the group which have been
      audited by PricewaterhouseCoopers, Chartered Accountants and Registered
      Auditors, for fiscal 1999 and Coopers & Lybrand, Chartered Accountants
      and Registered Auditors, for fiscal years 1995 to 1998. This selected
      financial data should be read in conjunction with, and is qualified in
      its entirety by reference to, such consolidated financial statements
      and their accompanying notes located on pages F-1 through F-40.

      ScottishPower prepares the consolidated financial statements of the
      group in accordance with accounting principles generally accepted in
      the U.K. ("U.K. GAAP"), which differs in certain significant respects
      from accounting principles generally accepted in the United States
      ("U.S. GAAP"). A description of the significant differences between
      U.K. GAAP and U.S. GAAP applicable to ScottishPower and a
      reconciliation of profit after taxation (or net income) and equity
      shareholders' funds (or shareholders' equity) under U.K. GAAP to those
      under U.S. GAAP are set out in Note 34 to the consolidated financial
      statements of the group.

      In the table below, amounts for fiscal 1999 have been translated,
      solely for the convenience of the reader, at $1.61 to (Pounds)1.00, the
      Noon Buying Rate in effect on March 31, 1999.

      The earnings per ScottishPower ADS have been calculated based on a
      ratio of four ScottishPower ordinary shares to one ScottishPower ADS.
      Dividends per ScottishPower ordinary share and per ScottishPower ADS
      exclude any associated U.K. tax credit available to certain holders of
      ScottishPower ordinary shares and ScottishPower ADS. See "Item 7.
      Taxation--Taxation of Dividends".

     /1/As permitted under U.K. GAAP, earnings per share has been presented
        above including and excluding the impact of the windfall tax and
        goodwill amortization, to provide an additional measure of underlying
        performance. In accordance with U.S. GAAP, earnings per share has been
        presented above based on U.S. GAAP earnings, without adjustments for the
        impact of windfall tax and goodwill amortization. As such additional
        measures of underlying performance are not permitted under U.S. GAAP,
        the inclusion of windfall tax in the determination of earnings for the
        purpose of computation of earnings per share in accordance with U.S.
        GAAP decreased earnings by (Pounds)317.0 million or 26.86 pence per
        share/(Pounds)1.07 per ADS for the year ended March 31, 1998. The
        inclusion on goodwill amortization decreased earnings by (Pounds)31.2
        million or 2.63 pence per share/(Pounds)0.11 per ADS for the year ended
        March 31, 1999, by (Pounds)29.8 million or 2.53 pence per
        share/(Pounds)0.10 per ADS for the year ended March 31, 1998, by
        (Pounds)23.7 million or 2.14 pence per share/(Pounds)0.09 per ADS for
        the year ended March 31, 1997 and by (Pounds)7.5 million or 0.84 pence
        per share/(Pounds)0.03 per ADS for the year ended March 31, 1996.
     /2/In fiscal 1996, the results included turnover of (Pounds)439.4 million
        and operating profit of (Pounds)37.7 million (net of reorganization
        costs of (Pounds)42.7 million explained below) in respect of Manweb for
        the period of the year following its acquisition on October 6, 1995. In
        September 1994, the Accounting Standards Board issued Financial
        Reporting Standard No. 7 on fair values in acquisition accounting. To
        comply with that reporting standard, reorganization and integration
        costs must be charged against post acquisition profits, and must not be
        reflected in the acquisition balance sheet. Accordingly, in line with
        the company's announcement in January 1996, the severance and
        reorganization costs of (Pounds)42.7 million associated with the
        acquisition of Manweb were charged against profits in the second half of
        fiscal 1996. (Pounds)28.2 million of the (Pounds)42.7 million represents
        accrual for severance costs (including

      Directors' severance costs) and (Pounds)14.5 million represents
      reorganization costs in areas such as contracting and retail. In fiscal
      1997, the results include turnover of (Pounds)316.2 million and
      operating profit of (Pounds)114.4 million (net of reorganization costs
      of (Pounds)21.2 million) in respect of Southern Water, for the period
      of the year following its acquisition on August 6, 1996.

      Dividends
      An interim dividend in respect of each fiscal year is normally declared
      by ScottishPower in November for payment in the following March. The
      final dividend in respect of each fiscal year is normally recommended
      by Directors in May and paid in October, following approval by
      ScottishPower's shareholders. A final dividend in respect of fiscal
      1999 of 15.00p net per ordinary share will be paid on October 4, 1999,
      making a total dividend of 22.50p net for fiscal 1999. The total
      dividend payable per ADS for fiscal 1999 was approximately $1.45 net
      based on the Noon Buying Rate in effect on March 31, 1999. The
      following table sets out the dividends paid on ordinary shares and ADSs
      in respect of the past five fiscal years, excluding any associated U.K.
      tax credit in respect of such dividends.

        "Item 7. Taxation--Taxation of Dividends". Dividends paid by the
        Depositary in respect of ADSs are paid in U.S. dollars based on a market
        rate of exchange that differs from the Noon Buying Rate.

     /3/Dividends have been translated from pounds sterling into U.S. dollars,
        solely for the convenience of the reader, at $1.61 to (Pounds)1.00, the
        Noon Buying Rate in effect on March 31, 1999. As dividends paid by
        ScottishPower are in pounds sterling, exchange rate fluctuations will
        affect the U.S. dollar amounts received by holders of ADSs on conversion
        by the Depositary of such cash dividends. See "--Exchange Rates" below.

      Future dividends will be dependent upon the group's earnings, financial
      condition and other factors. Although dividends have historically been
      declared and paid semi-annually, following completion of the merger
      with PacifiCorp, ScottishPower intends to move to quarterly reporting
      and payment of quarterly dividends. It is expected that a dividend will
      be paid in February, May, August and November of each year, which is
      consistent with the current timing of PacifiCorp's dividend payments.
      Interim and final dividends paid in the past are not necessarily
      indicative of future dividends. A person resident in the U.K. for tax
      purposes who receives a dividend from ScottishPower is generally
      entitled to a tax credit, currently at a rate of 1/9th of the dividend
      (the "associated U.K. tax credit"). For further information, see "Item
      7. Taxation--Taxation of Dividends".

      Exchange Rates
      Cash dividends are paid by ScottishPower in pounds sterling. Exchange
      rate fluctuations will affect the U.S. dollar amounts received by
      owners of the ADSs on conversion by the Depositary of such cash
      dividends paid. In addition, fluctuations in the exchange rate between
      pounds sterling and U.S. dollars will affect the U.S. equivalent of the
      quoted pound sterling price of ordinary shares on the London Stock
      Exchange, and as a result, will likely affect the market price of ADSs
      in the United States.

</TABLE>

      Group turnover grew during the year by (Pounds)114 million to
      (Pounds)3,242 million, an increase of 3.6%. This was due mainly to
      growth in the developing domestic gas area and telecommunications
      business. Gas and other energy sales were up by (Pounds)77 million to
      (Pounds)240 million, reflecting our continuing success in gaining new
      customers in the domestic market, and the total sales of
      ScottishTelecom were almost doubled at (Pounds)220 million.

      The rise in overall turnover, together with continued strong control
      over operating costs, led to good growth in earnings before interest,
      tax, depreciation and amortization (EBITDA), up (Pounds)66 million to
      (Pounds)1,017 million, and higher operating profit of (Pounds)803
      million, up (Pounds)18 million.

      The net interest charge increased by (Pounds)14 million to (Pounds)161
      million, mainly due to the impact on debt of the two windfall tax
      payments in December 1997 and December 1998, totaling (Pounds)317
      million, and the continued capital expenditure program.

      Profit before tax grew by (Pounds)4 million to (Pounds)644 million. At
      (Pounds)142 million, the ordinary tax charge represented an effective
      tax rate of 22.0%, reduced from 23.7% in the previous year.

      Earnings per share amounted to 42.42p, a rise of 2.8% on a comparable
      basis. One further measure of earnings per share in the financial
      statements is before windfall tax and amortization of goodwill. This
      amounted to 42.52p, an increase of 3% on the equivalent figure last
      year. The recommended final dividend of 15.00p net per share brought
      the total dividend per share for the year to 22.50p net, an increase of
      10.3%. This is in line with our aim of 7% to 8% real dividend growth
      per annum until at least the regulatory reviews in the year 2000,
      whilst

      maintaining a prudent level of dividend cover. The dividend cover
      reduced marginally to 1.9 times from 2.0 times the previous year.

      Free cash flow for the year, before windfall tax, was (Pounds)702
      million (as defined on page F-12), a reduction of (Pounds)32 million,
      reflecting working capital increases in our developing gas and
      telecommunications businesses. The group invested (Pounds)754 million
      in capital projects during the year, (Pounds)97 million more than in
      the previous year. This investment was primarily to improve the quality
      of the infrastructure assets in our electricity, and water and
      wastewater services businesses, and to support the growth of our
      telecommunications business.

      Net debt increased from (Pounds)1,953 million to (Pounds)2,421 million,
      mainly due to the continuing capital investment program. Gearing at
      March 31, 1999 increased to 124% compared to 114% a year ago. Interest
      cover remained prudent at 5.0 times.

      Group turnover of (Pounds)3,242 million was (Pounds)114 million higher
      than fiscal 1998, an increase of 3.6%. Total energy sales across the
      group were (Pounds)2,274 million, a reduction of (Pounds)6 million on
      the previous year. Higher sales volumes in the ScottishPower franchise
      area and further growth in our share of the domestic gas market were
      more than offset by lower revenues in Manweb and in the ScottishPower
      second tier and large business markets, due to competitive pricing.
      Southern Water's contribution to group turnover reduced by (Pounds)13
      million, reflecting the full-year impact of the disposal of non-core
      businesses in the prior year, with underlying business turnover
      increasing by (Pounds)19 million year-on-year. Scottish Telecom
      increased its total turnover by (Pounds)107 million to (Pounds)220
      million, with external sales rising by (Pounds)99 million to
      (Pounds)181 million. The group's other businesses increased their
      turnover by (Pounds)35 million.

      ScottishPower energy sales are divided into four market segments: first
      tier sales, which represent the sale of electricity to customers in the
      Scottish franchise area; second tier sales by ScottishPower to
      customers outside the Scottish franchise area; wholesale, which is the
      sale of electricity to other electricity companies and to the Pool in
      England and Wales; and gas and other energy sales, which include the
      sale of gas by ScottishPower in both the established commercial and
      industrial market and in the emerging domestic gas market in the U.K.

      First tier sales were (Pounds)1,116 million, an increase of (Pounds)5
      million on the previous year. Volumes increased in the year by 1.4% to
      19,831 GWh, primarily due to more normal winter weather following the
      unusually mild winter in 1997-98. Sales in the first tier competitive
      market were broadly in line with the previous year, despite prices
      being lower in the domestic and commercial sectors, and because of
      continued competition in the industrial sector.

      Sales of electricity in the second tier market sector reduced by
      (Pounds)16 million to (Pounds)137 million, with lower sales volumes
      outside our home territories as a result of exiting from loss-making
      business in this area.

      Wholesale turnover reduced in the year, down 7% to (Pounds)185 million,
      with higher export volumes, up by 442 GWh to 6,049 GWh, offset by lower
      Pool prices. Agency sales were 2.7% lower at 1,010 GWh.

      Gas and other energy sales increased by (Pounds)77 million to
      (Pounds)240 million, mainly as a result of our success in winning
      customers in the new domestic gas markets.

      Manweb's energy turnover for the year was (Pounds)596 million, a fall
      of (Pounds)58 million or 9% compared to the previous year. Distribution
      revenues increased by (Pounds)8 million, principally as a result of the
      regulatory pricing formula. The benefits of lower costs were passed on
      to domestic and business customers through reduced tariffs. The effect
      on profit from tariff reductions to the domestic and small business
      sectors, some (Pounds)20 million, was more than offset by improved
      performance elsewhere in the commercial and industrial sector, arising
      from exiting from loss-making business.

      Southern Water's contribution to group turnover fell by (Pounds)13
      million to (Pounds)440 million, due entirely to the previous year's
      disposal of the non-core businesses. Turnover in the regulated business
      increased to (Pounds)439 million, a rise of (Pounds)19 million compared
      to the previous year, due to higher prices to fund the capital
      expenditure program.

      Total sales in ScottishTelecom increased by (Pounds)107 million to
      (Pounds)220 million, including a contribution to group turnover of
      (Pounds)49 million from Demon Internet for the period since
      acquisition. Total turnover in Telecommunication Services increased by
      (Pounds)41 million to (Pounds)126 million, with total turnover in The
      CallCentre Service rising by (Pounds)3 million to (Pounds)12 million
      and in Information Services by (Pounds)14 million to (Pounds)33
      million. External turnover in ScottishTelecom increased by (Pounds)99
      million to (Pounds)181 million.

      The group's other businesses increased their turnover by (Pounds)35
      million to (Pounds)348 million. The Retail business, despite the poor
      market conditions during the year, increased its turnover to
      (Pounds)287 million due to new store openings, with like-for-like sales
      falling by 5.7%.

      Group Operating Costs
      The 0.5% increase in cost of sales to (Pounds)1,861 million compared
      favorably with the 3.6% increase in turnover. Cost of sales in the
      energy businesses increased due to the higher gas sales volumes.

<PAGE>


      Transmission and distribution costs increased by (Pounds)39 million
      year-on-year, largely due to customer capture costs in the growing
      electricity and gas supply businesses, together with costs of the
      severe winter storms in Scotland. Administrative expenses increased by
      (Pounds)46 million in the year, due to the expansion of our developing
      businesses, especially telecommunications, and increased rates and
      depreciation charges in our wires and pipes businesses.

      The group has continued to use benchmarking as a tool to reduce
      substantially underlying operating costs and improve performance during
      the year.

      In the Scottish energy businesses, Generation Wholesale announced a
      major new cost savings initiative, while Power Systems' continued
      reduction of core business costs has been achieved, principally through
      benchmarking and continued transfer of best practices--specifically by
      comparing performance between regions. Energy Supply achieved
      significant efficiency improvements through best practice transfer
      between ScottishPower and Manweb and from external benchmarking of cost
      and service performance.

      In Manweb further cost savings have been identified through best
      practice transfers with both the Power Systems and Energy Supply
      businesses.

      Cost reduction initiatives in Southern Water have achieved significant
      improvements in OFWAT ratings of cost performance in water and drainage
      businesses. Transition plan savings totaled (Pounds)10 million in the
      year, bringing total savings to (Pounds)41 million since acquisition.
      Further initiatives announced in September 1998 to build on the success
      of the transition plan will deliver additional cost savings.

      Group operating profit amounted to (Pounds)803 million, an increase of
      2.3% or (Pounds)18 million compared with fiscal 1998. This increase in
      group operating profit is after absorbing an additional (Pounds)28
      million of costs compared to the previous year, for capturing new
      energy and telecom customers, marketing the ScottishPower brand, and
      depreciation of new systems required to operate in the competitive
      electricity and gas markets.

      Operating profit in the Scottish energy businesses increased by
      (Pounds)2 million to (Pounds)397 million. Reduced Generation Wholesale
      profit from lower sales prices was more than offset by increased profit
      in Power Systems from higher distribution revenues and in Energy Supply
      from increasing domestic gas margins and improved performance in the
      second tier market.

      The profit in Generation Wholesale was (Pounds)115 million in the year,
      down (Pounds)16 million compared with fiscal 1998. Higher electricity
      volumes were sold at lower prices, both to our Energy Supply business
      and to the wholesale
ScottishPower Form 20-F 1999                                                  55

      market. In addition there were higher capacity and transmission
      charges. Interconnector capacity was increased in the year, with
      volumes up by 7.9%, but with contribution unchanged due to reductions
      in Pool prices.

      Power Systems increased profit by more than (Pounds)12 million to
      (Pounds)262 million. Transmission increased operating profit by
      (Pounds)3 million to (Pounds)84 million, due to price increases allowed
      under the regulatory formula. Distribution profits improved by
      (Pounds)9 million, as a result of higher distribution revenues from
      allowed price increases, higher sales volumes and a more favorable mix
      of units sold. Further business cost reductions were achieved, which
      partially offset increased depreciation charges and new industry costs
      associated with the operation of the competitive electricity market.

      In Energy Supply, first tier profit reduced by (Pounds)2 million to
      (Pounds)36 million, with lower generation costs more than offset by
      price reductions to customers and the costs of operating in the
      competitive electricity market. The impact of competition on financial
      performance in our first tier market has not been significant. The
      second tier segment recorded a break-even result, despite absorbing
      (Pounds)3 million of capture costs for new domestic electricity
      customers won in this market. Margins have been improved despite the
      competitive pressures in the large business sector of this market,
      primarily as a result of lower Pool prices and exit from loss-making
      contracts.

      In the commercial and domestic gas markets the operating loss of
      (Pounds)16 million reflects customer capture costs of (Pounds)17
      million this year, increased costs from serving the expanded customer
      base, in part offset by the margins obtained from supplying new gas
      customers in the domestic sector. Payback on our initial investment in
      acquiring a domestic gas customer is currently being achieved in 18
      months. Overall, Energy Supply profits increased by (Pounds)5 million
      to (Pounds)20 million.

      Operating profit in Manweb decreased by (Pounds)6 million to
      (Pounds)125 million. Increased depreciation charges and marketing costs
      in the competitive electricity market contributed to the reduction in
      profit, with price reductions passed on to customers offset by lower
      generation prices.

      Southern Water contributed more than (Pounds)21 million of additional
      operating profit, mainly from increased revenues and continuing cost
      savings of (Pounds)10 million delivered by the acquisition transition
      plan during fiscal 1999. These savings offset the additional (Pounds)7
      million costs of new obligations arising from the construction and
      operation of new wastewater treatment plants. Year-on-year, Southern
      Water's operating profit increased by 8.9% from (Pounds)241 million to
      (Pounds)262 million. All non-core businesses have been sold and,
      together with property sales, have realized (Pounds)129 million,
      (Pounds)29 million ahead of the target set at acquisition.

      ScottishTelecom's contribution to group operating profit was (Pounds)10
      million, up from (Pounds)5 million in fiscal 1998, with EBITDA higher
      by (Pounds)15 million to (Pounds)26 million. The improvement in
      operating profit reflects the increased volume of network traffic and
      growth in the provision of Internet services, resulting from our
      acquisition of Demon Internet on May 1, 1998. Operating profit for
      Demon totaled (Pounds)12 million including increased ingress receipts,
      with the Information Services business recording a profit of (Pounds)7
      million and The CallCentre Service (Pounds)2 million. Telecommunication
      Services recorded a loss of (Pounds)11 million, primarily from one-off
      customer capture costs and increased depreciation.

      Profits in the other businesses were (Pounds)8 million, (Pounds)5
      million lower than the previous year due to a fall in Retail's profits,
      as a result of difficult market conditions in this sector throughout
      fiscal 1999. Performance in the other businesses was in line with the
      prior year.

      Interest and Taxation
      The net interest charge of (Pounds)161 million was (Pounds)14 million
      higher than in fiscal 1998. This was due mainly to the full-year effect
      of increased debt on payment of the first installment of the windfall
      tax in December 1997, and part-year impact from the second installment,
      paid in December 1998. Changes to the group's debt portfolio were made
      during the year to take advantage of falling interest rates and to
      extend the maturity profile of the group's borrowings. As a result, the
      average interest rate for the group during the year was 8.0%, versus
      8.4% in fiscal 1998. Interest cover remained prudent at 5.0 times,
      against 5.3 times in the prior year. The effective tax rate was reduced
      to 22.0% from 23.7% in the previous year largely due to higher capital
      allowances on the current mix and level of capital expenditure.

      Earnings and Dividends
      The profit after ordinary tax for the year amounted to (Pounds)502
      million, an increase of (Pounds)14 million or 2.9%. With a weighted
      average 1,185 million shares in issue during the year, earnings per
      share were 42.42p before windfall tax, an increase of 2.8% on a
      comparable basis.

      The proposed final dividend of 15.00p net per share brings the total
      dividend per share for the year to 22.50p net, an increase of 10.3%.
      The full-year dividend was covered 1.9 times by earnings, versus 2.0
      times in fiscal 1998. This increase in dividend is in line with our
      stated aim of achieving 7% to 8% real dividend growth until at least
      the regulatory reviews in the year 2000, whilst maintaining a prudent
      level of dividend cover. It is ScottishPower's current aim to deliver
      real dividend growth thereafter and this will be re-examined once the
      outcome of the regulatory reviews is known.

</TABLE>

      Group turnover of (Pounds)3,128 million in fiscal 1998 was (Pounds)187
      million higher than in fiscal 1997, an increase of 6.4%. This was due
      mainly to a full year's revenue from Southern Water and growth in
      ScottishTelecom where sales more than doubled. Sales in our energy
      businesses were maintained, despite lower prices to our customers due
      to tariff reductions, competitive pricing outside ScottishPower's
      franchise area and lower volumes which resulted from the exceptionally
      mild winter. Offsetting this, gas sales were up by over 200% to
      (Pounds)60 million, reflecting our continuing success in gaining new
      customers in that market. Total domestic gas customers acquired at
      March 31, 1998 were 320,000.

      The rise in overall turnover together with continued strong control
      over operating costs led to good growth in EBITDA, up (Pounds)150
      million to (Pounds)951 million, and higher operating profit of
      (Pounds)785 million, up (Pounds)121 million.

      The net interest charge increased by (Pounds)39 million to (Pounds)147
      million, mainly due to the full year effect of additional borrowings
      associated with the acquisition of Southern Water in August 1996 and
      the payment of the first installment of the windfall tax in December
      1997.

      Profit before tax grew by 14.5% to (Pounds)640 million. At (Pounds)152
      million, the ordinary tax charge represented an effective tax rate of
      23.7%, down from 24.5% in the previous year. Provision has been made in
      full for the windfall tax on utilities announced in the July 1997
      budget; the liability for the group has been assessed at (Pounds)317
      million.

      Earnings per share before the windfall tax amounted to 41.28p, an
      increase of 8.3% compared to fiscal 1997. The recommended final
      dividend of 13.60p net per share brought the total dividend per share
      for fiscal 1998 to 20.40p net, an increase of 10.3% compared to fiscal
      1997. This is in line with ScottishPower's stated aim of 7% to 8% real
      dividend growth per annum, until at least the regulatory reviews in the
      year 2000, while maintaining a prudent level of dividend cover. The
      dividend cover remained at just over two times earnings before the
      windfall tax.

      Free cash flow for the year before windfall tax was (Pounds)734
      million, an increase of (Pounds)150 million compared to fiscal 1997,
      reflecting the improved operating performance and good control of
      working capital. The group invested (Pounds)657

ScottishPower Form 20-F 1999                                                  57

      million in capital projects during the year, (Pounds)186 million more
      than in the previous year. This investment was primarily to improve the
      quality of the infrastructure assets in the group's electricity and
      water and wastewater services businesses, and to grow the group's
      telecommunications business. The figures also reflect a full year of
      expenditure at Southern Water.

      Net debt increased from (Pounds)1,790 million to (Pounds)1,953 million,
      mainly due to payment of the first installment of the windfall tax of
      (Pounds)158 million.

      Gearing at March 31, 1998 reduced to 114% compared to 118% a year ago,
      despite the impact of part of the windfall tax. Excluding the effect of
      the windfall tax, gearing would have been 100%. Interest cover remained
      prudent at 5.3 times.

      Group turnover of (Pounds)3,128 million was (Pounds)187 million higher
      than fiscal 1997, an increase of 6.4%. Total energy sales across the
      group were (Pounds)2,280 million, the same as in the previous year.
      Lower sales as a result of the exceptionally mild winter, combined with
      competitive pricing in the second tier market and lower prices in the
      domestic market, were offset by increased sales in the emerging gas
      markets. Southern Water's contribution to group turnover increased by
      (Pounds)136 million, mainly reflecting the inclusion of the first full
      year's trading. ScottishTelecom turnover was (Pounds)45 million higher
      compared to fiscal 1997.

<PAGE>


      In the first tier market, sales were (Pounds)1,111 million, down
      (Pounds)39 million on the previous year. Volumes were reduced (down
      3.0% to 19,622 GWh) by the unusually mild Winter in fiscal 1998 and
      lower sales in the competitive part of this market. In addition, prices
      were lower due to tariff reductions in the domestic sector and
      competition in the commercial and industrial sector.

      In contrast, second tier volumes continued to grow with volumes
      increasing by 54%; turnover was (Pounds)51 million higher at
      (Pounds)153 million, reflecting our success in winning new customers.
      In addition, the further combination of the ScottishPower and Manweb
      sales forces led to all new customers contracting with ScottishPower.

      Wholesale electricity sales also increased in the year, up 2% to
      (Pounds)199 million, where the effect of lower export volumes, down 4%
      to 5,607 GWh due to system constraints in the first half of the year,
      was offset by higher agency sales.

      Gas and other energy sales increased by (Pounds)69 million to
      (Pounds)163 million in fiscal 1998, mainly as a result of the group's
      success in winning customers in the new domestic gas markets.

      Manweb's energy turnover for fiscal 1998 was (Pounds)654 million, a
      fall of (Pounds)84 million or 11% compared to the previous year.
      Distribution income reduced as a result of the regulatory pricing
      formula and the benefits of lower costs were passed on to domestic and
      business customers through reduced tariffs. In addition, the continued
      combination of the ScottishPower and Manweb sales forces led to further
      new industrial and commercial customers contracting with ScottishPower.

      Southern Water's contribution to group turnover increased by
      (Pounds)136 million to (Pounds)453 million primarily as a result of the
      full year effect. Turnover in the core business increased to
      (Pounds)420 million, an increase of (Pounds)21 million compared to the
      equivalent full year in fiscal 1997, due to higher prices to fund the
      capital expenditure program. In the non-core businesses, turnover for
      the full year fell by (Pounds)43 million, as expected, due to the
      business disposals achieved during the year.

      Turnover in ScottishTelecom increased by (Pounds)45 million in fiscal
      1998 to (Pounds)82 million reflecting the continued expansion through
      further organic growth and acquisitions. External turnover increased by
      122% to (Pounds)82 million and total turnover by 111% to (Pounds)113
      million.

      Turnover in the other businesses increased by (Pounds)23 million in
      fiscal 1998 to (Pounds)314 million. The Retail business, despite the
      poor market conditions experienced during the year, increased its
      turnover by (Pounds)7 million to (Pounds)274 million due to new store
      openings and increased sales of multimedia; however like-for-like sales
      fell by 4%.

      Group Operating Costs
      The 6.1% increase in cost of sales to (Pounds)1,851 million in fiscal
      1998 compared favorably with the 6.4% increase in turnover, reflecting
      the continued focus in the group on cost control and improved
      efficiency. Cost of sales in the energy businesses increased due to the
      higher gas and second tier sales volumes, offset by reduced other costs
      arising from benchmarking and cost initiatives.

      Operating costs at Manweb were (Pounds)24 million less than the
      previous year, beating the original target by (Pounds)6 million. In
      Southern Water on a full year basis, after allowing for higher costs
      from new environmental obligations and capital schemes, operating costs
      fell by (Pounds)28 million, (Pounds)3 million better than target. These
      operating cost reductions have been achieved principally as a result of
      synergies following acquisition and through the sale of non-core
      Southern Water businesses.

      Costs in Scottish Telecom increased due to business expansion.

      Transmission and distribution costs fell by (Pounds)3 million year-on-
      year despite the impact of initial domestic gas customer capture costs
      in the gas business and the repair costs necessary as a result of the
      severe Winter storms.

      Allowing for restructuring costs in the prior year arising on the
      acquisition of Southern Water, administrative expenses reduced due to
      savings which offset increases arising through the expansion in
      telecommunications. As with cost of sales, there is a continued drive
      on improving cost efficiency across all areas of the group.

     /1/Eight months from date of acquisition and after reorganization costs
       of (Pounds)21.2 million.

      Group operating profit was (Pounds)785 million in fiscal 1998, an
      increase of 18% compared to fiscal 1997. Operating profit in the
      Scottish Energy businesses fell by (Pounds)11 million to (Pounds)395
      million, due mainly to reduced generation profits and customer capture
      costs in the emerging gas markets. These were offset in part by lower
      costs and increased profit in Power Systems, mainly due to lower costs
      and increased distribution revenues.

      The profit in Generation Wholesale was (Pounds)131 million in fiscal
      1998, down (Pounds)15 million from fiscal 1997. The generation
      profitability was down (Pounds)9 million due to reduced volumes, higher
      depreciation and a greater volume of "must take' nuclear purchases. In
      wholesale, profit fell by (Pounds)6 million reflecting lower export
      volumes, as a result of system constraints, and reduced margins.

      The Power Systems business increased profit by (Pounds)22 million to
      (Pounds)250 million. Within this business, transmission increased
      operating profit by (Pounds)3 million to (Pounds)80 million with higher
      National Grid costs being more than offset by increased exit charges
      and savings from operating cost initiatives. The distribution profit
      increased by (Pounds)19 million as a result of higher distribution
      revenues and operating cost savings.

      In Energy Supply, first tier profit fell by (Pounds)1 million due to
      reductions in prices and the impact of lower volumes as a result of the
      mild Winter. Losses in the second tier market increased modestly to
      (Pounds)4 million due to the competitive pressures in this sector.
      Actions to stem further second tier losses have been taken and much of
      the unprofitable business has now been surrendered. In other energy
      sales, the operating loss of (Pounds)19 million reflects initial
      domestic customer gas capture costs of approximately (Pounds)12
      million, principally in the second half of the year.

      Operating profit in Manweb decreased slightly by (Pounds)4 million to
      (Pounds)131 million. A fall in turnover was offset by a reduction in
      costs due to the implementation of the last stage of the acquisition
      transition plan. Total operating cost savings arising from the
      acquisition of Manweb now total (Pounds)98 million compared to cost
      levels pre-acquisition of (Pounds)176 million, and ongoing cost savings
      are (Pounds)6 million better than the transition plan target.

      Southern Water contributed an additional (Pounds)126 million of
      operating profit arising mainly from the inclusion of results for a
      full year and cost savings of (Pounds)28 million delivered by the
      acquisition transition plan in fiscal 1998, (Pounds)3 million ahead of
      plan. Year-on-year, Southern Water's operating profit increased by 21%
      to (Pounds)241 million from (Pounds)200 million. All enterprise
      businesses are now sold and will realize (Pounds)90 million, (Pounds)20
      million ahead of target. Property disposal proceeds have already
      reached just under the target of (Pounds)30 million, with further sales
      scheduled in the year ahead.

      Profits in ScottishTelecom were (Pounds)5 million for the year, an
      increase of (Pounds)6 million meeting the previously announced target
      of (Pounds)4 million for the year from a (Pounds)1 million loss in the
      previous year.

      Profits in the other businesses were (Pounds)13 million for the year, a
      decrease of (Pounds)3 million after removing the effect of (Pounds)7
      million of gas capture costs included in this segment last year.
      Retail's profit fell from (Pounds)14 million to (Pounds)9 million due
      to the difficult market conditions in this sector throughout fiscal
      1998. The operating profits of the Contracting Services, Technology and
      other businesses improved from the prior year.

      Interest
      The net interest charge of (Pounds)147 million was (Pounds)39 million
      higher than in fiscal 1997 due mainly to the full year effect of
      increased debt following the acquisition of Southern Water in 1996 and
      the payment of the first installment of the windfall tax of (Pounds)158
      million in December 1997. Changes to the group's debt portfolio were
      made during the year to manage the increasing trend of interest rates
      and extend the maturity profile of the group's borrowings. As a result,
      the average interest rate for the group during the year was 8.4%,
      slightly below that for fiscal 1997. Interest cover remained prudent at
      5.3 times.

      Taxation
      Profit before tax grew by 14.5% to (Pounds)640 million, while the
      effective tax rate was reduced to 23.7% from 24.5% in the previous
      year. The decrease was mainly due to the reduction in the corporation
      tax rate arising from the July 1997 budget and the write back of
      Advance Corporation Tax, offset in part by the previous Chancellor's
      decision to reduce capital allowances on long life assets. Provision
      has been made in full for the windfall tax on utilities announced in
      the July 1997 budget. The liability for the group has been assessed at
      (Pounds)317 million.

      Earnings and Dividends
      The profit after ordinary tax for fiscal 1998 amounted to (Pounds)488
      million, an increase of (Pounds)66 million or 15.7%. With a weighted
      average 1,180 million shares in issue during the year, earnings per
      share before windfall tax were 41.28p, an increase of 8.3%.

      The recommended final dividend of 13.60p net per share brought the
      total dividend per share for the year to 20.40p net, an increase of
      10.3%. The full year dividend was covered just over two times by
      earnings excluding the effects of the windfall tax. This increase in
      dividend is in line with our stated aim of achieving 7% to 8% real
      dividend growth per annum until at least the regulatory reviews in the
      year 2000, while maintaining a prudent level of dividend cover.

      The group continued to increase investment in its businesses, with net
      capital expenditure for fiscal 1999 of (Pounds)754 million, an increase
      of (Pounds)97 million over fiscal 1998. This reflected increased
      expenditure on the capital program in Southern Water and the continued
      emphasis on growth of ScottishTelecom.

      Capital expenditure in Generation Wholesale was (Pounds)42 million,
      with investment directed towards efficiency and environmental
      improvements and development of gas storage facilities at Hatfield
      Moors. Further expenditure was incurred at Longannet and Cockenzie
      power stations to extend station lives.

      In Power Systems, net capital expenditure for the year amounted to
      (Pounds)128 million, a decrease of (Pounds)14 million. The distribution
      business spent (Pounds)36 million to improve the quality and
      reliability of the electricity supply to customers, and (Pounds)22
      million on expanding the network to meet demand for new electricity
      supply. More than (Pounds)42 million was invested in new systems for
      improved network management, the opening up of the electricity market
      to full competition, and on enhancing customer service.

      In transmission, (Pounds)28 million was invested to reinforce and
      refurbish specific parts of the overhead line system, and on network
      expansion to support new business opportunities.

      In Energy Supply, capital expenditure of (Pounds)24 million mainly
      reflected further investment in new systems for the liberalization of
      the electricity market, and in the development of Energy Services
      products for large business customers.

      Manweb capital expenditure amounted to (Pounds)86 million. (Pounds)26
      million was spent on modernizing the network to improve reliability and
      quality of electricity supply to customers. Net expenditure on
      expanding the network to meet demand growth and on providing new
      connections to customers was (Pounds)37 million. The balance was
      invested in enhancing customer service and business systems for the
      competitive market.

      Capital expenditure in Southern Water, including infrastructure renewal
      expenditure, amounted to (Pounds)347 million, compared with (Pounds)285
      million in the previous year. The amount included (Pounds)197 million
      as part of the ongoing program to ensure compliance with the higher
      standards set by European Union Directives on the quality of bathing
      water, urban wastewater discharges and sludge disposal. Investment was
      also undertaken to improve security of supply, increase the
      availability of water resources and reduce leakage in line with Water
      Summit commitments.

      Capital expenditure in ScottishTelecom amounted to (Pounds)103 million,
      with (Pounds)48 million associated with the expansion of network reach
      and capacity, including (Pounds)16 million in the north of Scotland and
      (Pounds)5 million for expansion in the Manweb territory. A further
      (Pounds)29 million of spending was attributable to Demon Internet,
      including expenditure related to the migration of Demon customers to
      the ScottishTelecom network and to acquiring increased transatlantic
      capacity.

      In the other businesses, Retail's capital expenditure totaled (Pounds)8
      million, most of which related to the opening of new stores.

      Cash Flow
      Net cash inflow from operations decreased from (Pounds)1,014 million to
      (Pounds)945 million. This reflected the group's investment in working
      capital, primarily in the growing gas and telecommunications
      businesses.

      Net interest paid of (Pounds)150 million was (Pounds)3 million higher
      than the equivalent figure in fiscal 1998, with increases due to the
      higher debt level, partly offset by a change in the mix of our debt
      portfolio. Ordinary tax paid decreased by (Pounds)41 million. Free cash
      flow for the group, before windfall tax, was (Pounds)702 million,
      (Pounds)32 million lower than in fiscal 1998. The payment of the final
      installment of windfall tax amounted to (Pounds)158 million and capital
      expenditure was (Pounds)683 million, up (Pounds)90 million on last
      year.

      Business acquisitions in the year totaled (Pounds)77 million, all of
      which were undertaken by ScottishTelecom. Of this total, (Pounds)66
      million related to Demon Internet, (Pounds)2 million to Watermark Games
      and the remainder comprised

      deferred consideration for prior year acquisitions of Megafone and
      Teledata. Dividends paid to shareholders amounted to (Pounds)253
      million, up from (Pounds)226 million last year.

      Net debt at March 31, 1999 was (Pounds)2,421 million, an increase of
      (Pounds)468 million compared with a year ago, principally due to
      payments of windfall tax and the increased program of capital
      expenditure. Gearing at March 31, 1999 was 124%, up from 114% at March
      31, 1998.

      Treasury

      Financing
      The treasury focus during the year was on further refinancing of the
      group's debt to minimize interest payments and reduce risk. The group
      continues to ensure that borrowings are financed from a variety of
      competitive sources and that committed facilities are available both to
      cover uncommitted borrowings and to meet the financing needs of the
      group in the future.

      Under the Euro-Medium Term Note (EMTN) Program, established in November
      1997, several issues were undertaken during the financial year. These
      included a (Pounds)250 million, 25 year, 6.75% issue in May 1998 and a
      DM725 million, 5.25%, 10-year issue in August 1998, providing a fixed
      rate in sterling of 6.79%. In addition to these, there were nine other
      smaller issues with maturities between two and ten years. Cumulative
      issues under the program reached a peak during the year of $1,870
      million and, as a result, the program limit was increased from $2,000
      million to $4,000 million. This increase will allow the group continued
      access to a variety of funding sources and the ability to tap market
      demand as and when appropriate. As part of the group's strategy to
      develop new funding sources, a (Pounds)150 million facility with the
      European Investment Bank was completed in December. Drawings under the
      facility as at the balance sheet date totaled (Pounds)51 million.

      On March 12, 1999 the company's (Pounds)2,600 million revolving credit
      facility was renegotiated in order to allow for the merger with
      PacifiCorp. In effect this meant reducing it to (Pounds)2,000 million,
      incorporating the creation of a new holding company and raising the
      margin. At the same time a new facility of (Pounds)600 million was
      arranged in order to finance maximum working capital requirements
      during the next 12 to 18 months. This facility has a 364-day life with
      an option to extend it to June 2001, the same maturity date as the
      (Pounds)2,000 million facility.

      The group continues to manage interest rate exposure by maintaining the
      majority of its debt at fixed rates of interest. This is achieved by a
      combination of fixed rate debt issues and the conversion of floating
      rate issues into fixed rate obligations by the use of interest rate
      swaps, interest rate caps and forward rate agreements. The use of
      financial instruments relates directly to underlying indebtedness; no
      speculative or trading transactions are undertaken. The group treasury
      operates strictly within policies set out by the Board and is subject
      to regular examination by internal and external audit. At March 31,
      1999, the interest rate on some 77% of debt was fixed and the interest
      rate on a further 8% of borrowings was capped.

      Risk Management
      The main financial risks faced by the group are exchange rate risk,
      interest rate risk and Pool price risk. The Board has reviewed and
      agreed policies for managing each of these risks as summarized below.
      The use of all classes of financial instruments to manage these risks
      has been approved by the Board. The group treasury, which is authorized
      to conduct the day-to-day treasury activities of the group, reports at
      least annually to the Board and is subject to examination by internal
      audit. The Energy Trading Center, which is authorized to carry out
      activities to manage the group's Pool price risk, reports monthly to a
      risk committee which is comprised of two executive Directors and an
      external consultant. The Energy Trading Center also reports at least
      annually to the Board and is subject to examination by internal audit.

      The weighted average period of maturity of year-end fixed debt and
      swaps was nine years, while the forward cover on capped debt was for an
      average period of some three years. Accordingly, changes in floating
      interest rates will have a limited impact on interest payable by the
      group.

ScottishPower Form 20-F 1999                                                  63
<PAGE>


      In order to reduce the weighted average cost of capital by improving
      the efficiency of the balance sheet, the group is targeting an "A'
      credit rating, which implies a minimum interest cover of approximately
      3.0 times. It is expected that the merger with PacifiCorp will be
      structured in order to achieve this aim. As a result, the group's long-
      term credit ratings may decline from the current levels of Aa3 (Moody's
      Investors Service) and A+ (Standard & Poor's), both of which are under
      review for possible downgrade. The short-term credit ratings of P1/A1
      are not under review.

      The group has limited exposure to foreign currencies. Commercial paper
      and EMTNs issued in currencies other than sterling are fully covered by
      forward contracts or swaps to convert the debt into sterling. Certain
      limited imports of capital equipment and fuel are denominated in
      foreign currencies and the sterling cost of these is fixed by means of
      forward contracts as soon as the company's contractual commitments are
      known.

      The group has procedures in place to minimize exposure to Pool price
      variations, being the possibility that a change in Pool prices will
      reduce the proceeds of electricity sold to the Pool or increase the
      cost of electricity purchased from the Pool. These involve
      ScottishPower and its subsidiary Manweb entering into contracts for
      differences (CfDs). CfDs are contracts which fix the price of
      electricity for an agreed quantity and duration by reference to an
      agreed strike price. The group's use of such derivative instruments
      relate directly to the underlying purchase and sale of electricity to
      and from the Pool.

      In ScottishPower, the risk management efforts of the energy businesses
      are focused on electricity supply and generation, which are exposed to
      Pool price volatility.

      On the supply side, the group sells predominantly fixed price contracts
      to customers and buys output from the Pool to meet the demand of these
      customers. Since the price of electricity purchased from the Pool can
      be volatile, the group is exposed to risk arising from differences
      between the fixed price at which it sells electricity and the
      fluctuating prices at which it purchases electricity, unless it can
      effectively hedge such exposure.

      The group's generation business is also exposed to fluctuations in Pool
      price. It sells electricity through the Pool, via the Anglo-Scottish
      Interconnector. Sales of electricity to other suppliers in Scotland are
      also made at a price related to the Pool price. In addition, the
      generation business purchases electricity from Scottish Nuclear under
      the terms of the Nuclear Energy Agreement, at a Pool-related price.

      The group's exposure to Pool price risk is managed by its Energy
      Trading Center. The role of the Energy Trading Center is to monitor the
      group's overall energy price exposure and hedge this risk where
      appropriate. In the electricity market the primary hedging tool is
      CfDs.

      The Energy Trading Center manages CfDs by reference to its own internal
      forecasts of customer demand, volume available for Pool trading and
      Pool prices and bases its choices on the interpretation of these
      forecasts and market intelligence.

      Bilateral contracts are then entered into with RECs, generators and
      other large electricity consumers to mitigate Pool price risk. These
      contracts are typically settled monthly for cash, based on the actual
      variance of Pool prices to the agreed CfD strike price. Therefore,
      these contracts do not involve actual delivery of the underlying
      commodity. These CfDs involve a degree of credit risk. This is the risk
      that the counterparty to the CfD defaults on settlement. The group
      controls credit risk arising from holding the CfDs through credit
      approvals, limits and monitoring procedures.

      The operation of the Energy Trading Center is carried out under strict
      guidelines which are agreed and monitored by the Risk Management
      Committee, whose membership includes the Executive Finance Director and
      the Executive Director, U.K. Power Operations. In addition, the
      operation of the Energy Trading Center is monitored by internal audit.

      The group's ability to manage both its purchase price risk and its
      sales price risk depends, in part, on the continuing availability of
      properly priced risk management mechanisms such as CfDs. However,
      because the CfD market in electricity is very illiquid, no assurance
      can be given that an adequate, transparent market for such products
      will in fact be available.

      Recent Developments
      ScottishPower has announced proposals for the creation of a new holding
      company for the group, subject to Court approval. A new holding company
      will be introduced to formalize the separation between the ultimate
      holding company, the existing trading activities of the group and
      PacifiCorp. These changes, expected to take effect at the end of July,
      are in line with the position held by both the U.K. and U.S. Federal
      regulatory authorities, who favor the corporate structure of a "non-
      trading" holding company.

      The first sitting of both the Scottish Parliament and the Welsh
      Assembly took place on May 12, 1999 with devolved powers being assumed
      from July 1, 1999. No party gained overall control in either the
      Scottish Parliament or the Welsh Assembly. The Rt. Hon Donald Dewar MSP
      has been elected First Minister of the Scottish Parliament. In
      Scotland, a coalition agreement has been formed between the Scottish
      Labour Party and the Scottish Liberal Democrats. The Rt. Hon Alun
      Michael AM has been elected First Minister of the Welsh Assembly and
      the Labour Party has formed a minority administration.

      The group has continued to make a very positive contribution to the
      devolution process, which it believes will offer opportunities for
      business. The retention of a "level playing field" across the industry
      in the U.K. remains a centrally important issue. Given that regulatory
      control and macro economic policy is to be retained by Westminster,
      parity is expected to continue. Powers to control and even further
      legislate on local planning, business rates and environmental issues
      will be devolved to the new Parliament as will power to implement EU
      directives and legislation. The Welsh Assembly does not have the power
      to introduce primary legislation and will act as an administrative body
      for the implementation of those powers historically held by the
      Secretary of State for Wales. However, the Assembly will have a large
      scope to concentrate on areas such as economic development, which have
      been expanded through the enhanced operation of a central development
      agency, planning issues and education, again providing positive
      business opportunities.

      In line with ScottishPower's commitment to develop effective working
      relationships with all political audiences, a full contact program
      strategy has been developed and will be implemented in both the
      Scottish Parliament and the Welsh Assembly. Close monitoring of
      developments in Scotland and Wales is also essential to ensure that the
      group identifies positive opportunities as they arise.

      Outlook
      Apart from the many changes and opportunities which the year ahead
      offers in the U.K. operations, it is expected the PacifiCorp merger
      will be completed later this year. This would make ScottishPower one of
      the top 10 electricity companies in the world and would bring the total
      employment complement in the new enlarged group to 25,000.

      Looking forward into the new millennium, regulation will continue to
      have a significant bearing on the profitability and investment
      capability of the group. The Directors believe that the group has high
      standards of operation and customer service. Nevertheless, they are
      unable to judge accurately the outcome of the current U.K. regulatory
      reviews and there can be no assurance that they will not materially
      affect the group's profits.

      ScottishPower's goal is to provide better service and value to
      customers and at the same time enhanced earnings for shareholders. This
      must be supported by a process of regulation which takes a balanced
      long-term view to reward investment and encourages improvements in
      service and efficiency.

      ScottishPower will continue its strategy to develop and grow the
      business. This will require ongoing revenue and capital investment in
      the year ahead. ScottishPower is confident in its strategy for long-
      term growth and, given the quality of the company and its people, looks
      forward to further success.

      European Economic and Monetary Union and the impact of the euro
      European Economic and Monetary Union (EMU) commenced on January 1, 1999
      with the introduction of a new currency, the euro.

      The group's businesses are almost totally domestic in nature, with very
      few sales denominated in currencies other than sterling, and relatively
      few purchases. As a result, while the United Kingdom remains outside
      EMU, the group

ScottishPower Form 20-F 1999                                                  65

      will be affected to only a very minor extent by the introduction of the
      euro. A project team has been established to review the impact of the
      first wave of EMU on customers and suppliers and to formulate the
      group's response. The project group is also considering the
      implications of potential U.K. membership of EMU.

      The benefits of a new integrated capital market have been recognized
      and the group has already issued commercial paper denominated in euros
      and will consider issuing bonds in euros in due course.

      U.K. GAAP to U.S. GAAP Reconciliation
      Under U.S. GAAP, profit after ordinary and windfall taxation for fiscal
      1999 and fiscal 1998 was (Pounds)455.0 million and (Pounds)129.8
      million, respectively, compared with (Pounds)502.8 million and
      (Pounds)170.1 million under U.K. GAAP. Equity shareholders' funds under
      U.S. GAAP at the end of fiscal 1999 and fiscal 1998 were
      (Pounds)2,460.8 million and (Pounds)2,252.6 million compared with
      (Pounds)1,945.9 million and (Pounds)1,707.8 million under U.K. GAAP.
      Differences result principally from the differing accounting treatment
      of pension costs, goodwill, deferred taxation and the recognition of
      dividend payments. For details of these differences, see Note 34 to the
      Consolidated Financial Statements of the group.

      Item 9A. Quantitative and Qualitative Disclosures About Market Risk

      Market Rate Sensitive Instruments and Risk Management
      The following discussion about the group's risk management activities
      includes "forward looking" statements that involve risk and
      uncertainties. Actual results could differ materially from those
      projected in the forward looking statements.

      The following tables summarize the financial instruments, derivative
      instruments and derivative commodity instruments held by the group at
      March 31, 1999, which are sensitive to changes in interest rates,
      foreign exchange rates and commodity prices. The group uses interest
      rate swaps, forward foreign exchange contracts and other derivative
      instruments to manage the primary market exposures associated with the
      underlying assets, liabilities and committed transactions. The group
      uses these instruments to reduce risk by essentially creating
      offsetting market exposures. The instruments held by the group are not
      leveraged and are not held for financial trading purposes.

      Financial Instruments and Risk Management

      Overview
      The main financial risks faced by the group are exchange rate risk,
      interest rate risk and Pool price risk. The Board has reviewed and
      agreed policies for managing each of these risks as summarised below.
      In order to mitigate the risks identified the Board has endorsed the
      use of financial instruments. The financial instruments endorsed for
      use by the Board include swaps, both interest rate and cross currency,
      caps, forward rate agreements, forward contracts and contracts for
      differences. The group treasury, which is authorized to conduct the
      day-to-day treasury activities of the group, reports annually to the
      Board and is subject to both internal and external audit. The Energy
      Trading Center, which is authorized to carry out activities to manage
      the group's Pool price risk reports monthly to a risk committee which
      is comprised of two executive directors and an external consultant.
      Pool price risk is defined as the possibility that a change in the cost
      of electricity from the Pool will either reduce the proceeds of
      electricity sold to the Pool or increase the cost of electricity

      Interest rate risk management
      The group continues to access funding opportunities in the major global
      markets in a range of currencies at both fixed and floating rates of
      interest, using derivatives where appropriate, to convert the
      obligations and payments into fixed or floating rate sterling.

      The exposure to fluctuating interest rates is managed by using a
      spectrum of financial instruments to maintain a majority of the group's
      debt portfolio at fixed rates. This involves either issuing fixed rate
      debt or swapping floating rate debt obligations into fixed rates by
      either interest rate swaps or a string of forward rate agreements
      ("FRA"). Flexibility in the fixed/floating mix is maintained by using
      interest rate caps that protect the group should rates rise, i.e. above
      the strike price, while maintaining the potential benefit should
      interest rates fall. The overall policy framework with regards to the
      fixed/floating debt mix has been approved by the Board. At March 31,
      1999, 77% (1998:81%) of the group's debt was either issued as fixed or
      converted to fixed rates using interest rates swaps. No FRAs were
      outstanding as at March 31, 1999.

      All transactions are undertaken to manage the risks arising from
      underlying activities and no speculative trading is undertaken. The
      counterparties to these instruments generally consist of financial
      institutions and other bodies with good credit ratings, i.e. "AA" rated
      by any one of the following, Standard & Poor's, Moody's or Duff &
      Phelps. Although the group is potentially exposed to credit risk in the
      event of non-performance by counterparties, such credit risk is
      controlled through credit rating reviews of the counterparties and by
      limiting the total amount of exposure to any one party to levels agreed
      by the Board. The group does not believe that it is exposed to any
      material concentration of credit risk.

      The following table indicates the type of swaps used, their duration,
      their respective interest rates, the maturity profile of the foreign
      currency denominated borrowings and the currency of issue. Average
      variable rates are based on rates that are implied by the yield curve
      at March 31, 1999. These may change significantly, affecting future
      cash flows. The information is presented in pounds sterling
      equivalents, the reporting currency of the group. For avoidance of
      doubt, reference to "m" in "m LIBOR" represents months, not millions.

      The assumptions used to estimate current fair values of debt and other
      financial instruments are summarized below:
      (i)   For cash, short-term deposits and short-term borrowings (uncommitted
            borrowing, commercial paper, and short-term borrowings under the
            committed facilities) the book value approximates to fair value
            because of their short maturities.
      (ii)  The fair values of all quoted euro bonds are based on their
            closing clean market price converted at the spot rate of exchange
            as appropriate.
      (iii) The fair values of the sterling bond 2001 and the European
            Investment Bank loans have been calculated by discounting their
            future cash flows at market rates adjusted to reflect the
            redemption adjustments allowed under each agreement.
      (iv)  The fair values of the sterling interest rate swaps and sterling
            interest rate caps have been estimated by calculating the present
            value of estimated cash flows.
      (v)   The fair values of the cross currency interest rate swaps have been
            estimated by adding the present values of the two sides of each
           swap. The present value of each side of the swap is calculated by
           discounting the estimated future cash flows for that side, using
           the appropriate market discount rates for that currency in effect
           at the balance sheet date.
      (vi) The fair values of unquoted debt have been calculated by
           discounting the estimated cash flows for each instrument at the
           appropriate market discount rate in the currency of issue in
           effect at the balance sheet date.

      (a) Foreign exchange risk management
      The primary source of foreign exchange risk is from the foreign
      exchange risk associated with the issue of debt sourced in a foreign
      currency, i.e. debt issued in currencies other than sterling. The
      foreign exchange exposure on the debt is eliminated entirely by the use
      of cross currency interest rate swaps. The group has a policy to hedge
      all contractually committed income/expenditure denominated in
      currencies other than sterling into sterling by the use of spot and
      forward contracts.

      (b) Commodity price risk management
      Almost all electricity generated in England and Wales must be sold to
      the Pool. Electricity suppliers including Manweb and ScottishPower must
      buy electricity from the Pool for resale to their customers in England
      and Wales. The Pool was established at the time of privatization in
      England and Wales for bulk electricity trading between generators and
      suppliers. ScottishPower participates in the Pool by
      exporting/importing electricity to/from England and Wales via the
      interconnector and purchasing electricity from the Pool to meet the
      requirements of its customers in England and Wales. The Pool is
      operated under a Pooling and Settlement Agreement to which all licensed
      generators and suppliers of electricity in Great Britain are party.

      The group has procedures in place to minimize exposure to Pool price
      variations, that is, the possibility that a change in Pool prices will
      reduce the proceeds of electricity sold to the Pool or increase the
      cost of electricity purchased from the Pool. These procedures involve
      ScottishPower and its subsidiary Manweb entering into contracts for
      differences (CfDs) with third parties. In general, the terms of CfDs
      are such that contracts are settled monthly (or more frequently) in
      arrears by reference to actual half hourly Pool prices.

      A CfD is a contract between two parties (e.g. a generator and a public
      electricity supplier) that requires each party to either make or
      receive monthly payments over a specific term based on the difference
      between an agreed price (i.e. the bilaterally determined strike price)
      and a price that varies with a specified commodity index (i.e. the
      Pool), applied to an agreed quantity (i.e. number of MWhs). The group's
      policy is to hedge the net electricity sales to or purchases from the
      Pool.

      During the year ended March 31, 1999, more than 90% of the group
      exposure to Pool prices was hedged in this way. Cover is built up
      throughout the year and at March 31, 1999 a significant proportion of
      the group's exposure to Pool price variations for the following
      financial year is covered.

      The group has also entered into some longer term (in excess of one
      year) arrangements to protect against the volatility of Pool prices.
      These arrangements have the potential to be increased at
      ScottishPower's discretion as the business grows and the time period
      covered will be reviewed on an ongoing basis. The contracts specify the
      price indexation that applies.

<PAGE>


      CfDs involve a degree of credit risk. This is the risk that the
      counterparty to the CfD defaults on settlement. The counterparties
      dealt with include generators, suppliers and financial institutions.
      The group controls credit risk arising from holding the CfDs through
      credit approvals, limits and monitoring procedures.

</TABLE>

      The notional amount represents the gross volume covered under the
      contracts multiplied by the respective strike prices. The fair value
      represents the forecast future cash flows at current market prices.
      CfDs are both bought and sold depending on whether ScottishPower is
      exposed as a buyer from or seller to the Pool.

      The difference between these figures and those reported last year is
      due to the inclusion of new CfDs which were entered into during fiscal
      1999.

      It is difficult to estimate the long term level of Pool prices with
      reasonable accuracy and there is no readily identifiable market through
      which the CfDs could be realized in an exchange. However, based on
      management projections of the future prices of electricity, and
      considering the outcome under several future price scenarios, the group
      has determined that the fair value amount of CfDs, outstanding at the
      year end, is not material to the group's Accounts. The fair value
      amount is the difference between the strike price of the contract and
      the estimated Pool price for the relevant half hourly periods.

      Item 10. Directors and Officers of Registrant

      The business of ScottishPower is managed by the Board of Directors.
      ScottishPower's Articles of Association provide that at every Annual
      General Meeting of ScottishPower one third (or the number nearest to
      but not exceeding one third) of the Directors shall retire from office.
      The Directors to retire in each year are the Directors who have been
      longest in office since their appointment or re-appointment. A retiring
      Director is eligible for re-appointment. The Directors may, at any
      time, appoint any person to be a Director. Any person so appointed will
      hold office until the next Annual General Meeting and shall then be
      eligible for election. The Directors may appoint one or more of their
      number to the office of Managing Director or to any other executive
      office for such period and on such terms as the Directors think fit.
      The executive Directors have two year rolling employment contracts with
      ScottishPower, other than Charles Berry and Alan Richardson who have
      service contracts terminable on one year's notice. The executive
      officers have contracts that are terminable by the company on the
      serving of one year's notice.

      The non-executive Directors, the executive Directors and the executive
      officers of ScottishPower are as follows:

      Awards will vest only if the Remuneration Committee is satisfied that
      certain performance measures related to the sustained underlying
      financial performance of the company and improvements in certain OFFER
      published Customer Service Standards and OFWAT published levels of
      service (in the case of awards granted in 1997 and 1998) are achieved
      over a period of three financial years commencing with the financial
      year preceding the date an award is made.

      Assuming that such targets have been achieved, the number of shares
      that can be acquired will depend upon how the company ranks in terms of
      its total shareholder return performance over a three year period, in
      comparison to the constituent companies of the FTSE 100 Index and the
      electricity and water sectors.

      Following the acquisition of Southern Water, participants in the
      Southern Water Sharesave Scheme were offered the opportunity to
      exchange existing options over Southern Water shares on the basis of
      3.3514 ScottishPower shares under replacement options for every one
      Southern Water share under option. Consequently, the number of shares
      under options and the option prices were adjusted on this basis for
      participants exchanging options.

      Item 16. Changes in Securities and Changes in Security for Registered
               Securities

      (a) Ordinary shares 50p each/American Depositary Shares
          For a discussion of the proposed scheme of arrangement whereby New
          ScottishPower will become the new holding company for the group, see
          "Item 1. Description of Business--Introduction--Scheme of
          Arrangement." If this occurs, in exchange for ADSs or ordinary
          shares of ScottishPower, shareholders will receive ADSs or ordinary
          shares of New ScottishPower, with the same economic and voting
          rights as the ADSs and ordinary shares of ScottishPower.

          The rights attaching to the New ScottishPower ordinary shares will
          be substantially the same as those attaching to the ScottishPower
          ordinary shares. A copy of the Memorandum and Articles of
          Association of New ScottishPower was previously filed with the
          registrant's Form F-4, file no. 333-77877, exhibit 3(i)(a), filed
          with the U.S. Securities and Exchange Commission in May 1999.

          The principal differences between the New ScottishPower Articles and
          the ScottishPower Articles are explained below. The numbering of the
          New ScottishPower Articles (each an "article") referred to below
          corresponds to the numbering of the ScottishPower Articles, other
          than article 6(E) which is a new article and has no equivalent in
          the ScottishPower Articles.

          (1) Article 6(E) (The Redeemable Shares)
          This article was inserted to set out the rights attaching to the
          49,998 redeemable shares of (Pounds)1 each in New ScottishPower (the
          "Redeemable Shares") issued to ScottishPower in order for it to
          obtain a trading certificate under section 117 of the Companies Act
          1985 (as amended). By virtue of a special resolution of New
          ScottishPower passed on April 29, 1999, this article will
          automatically be deleted from the New ScottishPower Articles
          following redemption of all of the Redeemable Shares.

          (2) Article 7 (The New ScottishPower Special Share)
          This article sets out the rights attaching to the New ScottishPower
          Special Share and has been amended so that in addition to those
          matters which are currently deemed in the ScottishPower Articles to
          be a variation of the rights attaching to the ScottishPower Special
          Share and as such only effective with the prior consent in writing
          of the Special Shareholder, the rights attaching to the New
          ScottishPower Special Share provide that each of the following
          matters is also deemed to be a variation requiring the prior consent
          of the Special Shareholder in writing:

          (i)   the giving by New ScottishPower of any consent or agreement to
                any amendment, removal or alteration of the effect of article 7
                of the ScottishPower Articles (as amended in connection with the
                scheme of arrangement);

          (ii)  the giving by New ScottishPower of any consent or agreement to
                the creation or issue of any shares in the capital of
                ScottishPower other than an issue of shares following which New
                ScottishPower will own the full legal and beneficial interest
                in, and control, shares in the capital of ScottishPower carrying
                at least 85% of the voting rights exercisable on a poll at
                general meetings of ScottishPower;

          (iii) the disposal by New ScottishPower of any of the shares in
                ScottishPower held by it or of any rights or interest in such
                shares or the entering into by New ScottishPower of any
                agreement or arrangement with respect to such shares or to the
                exercise of any voting or other rights attaching to such
                shares, such that New ScottishPower would cease to own the
                full legal and beneficial interest in, and control, shares in
                the capital of ScottishPower carrying at least 85% of the
                voting rights exercisable on a poll at general meetings of
                ScottishPower;

<PAGE>


          (iv) the giving by New ScottishPower of any consent or agreement to
               any abrogation, variation, waiver or modification of any of the
               rights or privileges attaching to any shares in ScottishPower
               such that New ScottishPower would cease to own the full legal
               and beneficial interest in, and control, shares in the capital
               of ScottishPower carrying at least 85% of the voting rights
               exercisable on a poll at general meetings of ScottishPower; and

          (v)  any other act or omission to act by New ScottishPower or the
               Directors of New ScottishPower which results in New ScottishPower
               ceasing to own the full legal and beneficial interest in, and
               control, shares in the capital of ScottishPower carrying at least
               85% of the voting rights exercisable on a poll at general
               meetings of ScottishPower.

          (3)Article 98 (Number of Directors to retire)
          This article relates to the number of Directors to retire from
          office by rotation and has been amended in accordance with the new
          London Stock Exchange requirement that all Directors shall retire by
          rotation at least every three years.

          (4)Article 123 (Borrowing powers)
          This article relates to the borrowing powers of New ScottishPower
          and has been amended to include an interim borrowing limit of
          (Pounds)8 billion up to the date of publication of the audited
          accounts of New ScottishPower for the year ended March 31, 2000, and
          to delete the provision which required goodwill and intangible
          assets to be deducted from the Adjusted Capital and Reserves (as
          defined in the New ScottishPower Articles). This deletion reflects
          the U.K. Financial Reporting Standard FRS10.

          (5)Article 130 (Interim dividends)
          This article relates to the ability of the Directors to pay interim
          dividends and has been amended to provide that the Directors may
          declare and pay any dividends, including final dividends, and not
          just interim dividends. This is in order to facilitate the proposed
          move to quarterly dividend payments.

          (6)CREST
          Articles 2 ("Definitions") and 51 ("Limitations on Shareholdings")
          have been amended to reflect the introduction of CREST.

          (7)Removal of interim privatization arrangements
          Articles 2 ("Definitions"), 50 ("Disclosure of interests in shares")
          and 51 ("Limitations on Shareholdings") have been amended to remove
          references to certain interim arrangements originally included in
          relation to the privatization of ScottishPower.

          Future Proposals
          The Directors intend pursuant to the Merger agreement with
          PacifiCorp to propose a resolution at the 2000 Annual General
          Meeting of New ScottishPower to amend the New ScottishPower Articles
          in order to provide (to the extent reasonably possible) for the
          holders of ADSs to attend, vote and speak at general meetings. It is
          intended that the amendments to be proposed will provide for the
          appointment of multiple proxies by approved depositories, for such
          proxies themselves to be able to appoint a proxy, for the holding of
          special and extraordinary resolutions on a poll and for certain
          other minor amendments to the New ScottishPower Articles.

          The Merger with PacifiCorp is not conditional upon the passing of
          this resolution although the Merger agreement requires that the
          resolution, if not passed, would again be put forward for
          consideration at the next annual general meeting.

          New ScottishPower also intends to seek to amend its depository
          agreement to reflect the changes proposed to be made to the New
          ScottishPower Articles and to make certain other amendments.

      (b) No rights evidenced by any class of registered securities have been
          materially limited or qualified by the issuance or modification of
          any other class of securities.

      (c) There are no assets securing any class of registered securities of
          the company.

      (d) There are no trustees or paying agents for any registered
          securities of the company.

      Consolidated Financial Statements of Scottish Power plc
      for the year ended March 31, 1999

      Accounting Policies and Definitions

      Basis of accounting
      The Accounts have been prepared under the historical cost convention,
      modified to include the revaluation of certain tangible fixed assets,
      and in accordance with applicable accounting standards in the U.K. and,
      subject to the treatment of water infrastructure grants and
      contributions described under "Grants and contributions" below, comply
      with the requirements of the Companies Act 1985.

      In preparing these Accounts, certain reclassifications and changes in
      presentation have been made to the Accounts previously presented in
      ScottishPower's published U.K. Annual Report and Accounts, with the
      exception of the consolidated cash flow statements, in order to comply
      with accounting presentation and disclosure requirements applicable in
      the United States. A reconciliation to U.S. GAAP is set out in Note 34.

      Basis of consolidation
      The group Accounts include the Accounts of the company and its
      principal subsidiary undertakings together with the group's share of
      results and net assets of associated undertakings and joint ventures.
      For commercial reasons one subsidiary has a different year end. The
      consolidation includes the Accounts of this subsidiary as adjusted for
      material transactions in the period between its year end and March 31.

      Use of estimates
      The preparation of Accounts 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
      Accounts and the reported amounts of revenues and expenses during the
      reporting period. Actual results can differ from those estimates.

      Turnover
      Turnover comprises the sales value of energy, goods, water, wastewater
      and other services supplied to customers during the year and excludes
      Value Added Tax and intra-group sales. Income from the sale of energy
      and measured water is the value of units supplied during the year and
      includes an estimate of the value of units supplied to customers
      between the date of their last meter reading and the year end.

      Under/over recovery of regulated income
      Under the licences issued to Scottish Power plc and Manweb plc which
      permit them to operate as public electricity companies, price control
      formulae determine the regulated allowable maximum unit revenues of the
      transmission and distribution businesses, as appropriate. If actual
      revenue for the year exceeds the regulated allowable maximum, the
      excess is deducted from turnover and included in creditors where
      amounts are due to be returned to customers. Where there is an under
      recovery compared with the regulated allowable maximum no anticipation
      of any potential future recovery is made.

      Research and development
      Expenditure on research and development is charged to the profit and
      loss account as it is incurred.

      Interest
      Interest on the funding attributable to major capital projects is
      capitalized gross of tax relief during the period of construction and
      written off as part of the total cost over the operational life of the
      asset. All other interest payable and receivable is reflected in the
      profit and loss account as it arises.

F-1                                                 ScottishPower Form 20-F 1999

<PAGE>

      Financial instruments
      Debt instruments
      All borrowings are stated at the fair value of consideration received
      after deduction of issue costs. The issue costs and interest payable on
      bonds are charged to the profit and loss account at a constant rate
      over the life of the bond.

      Interest rate swaps
      Interest rate swap agreements are used to manage interest rate
      exposures and are accounted for using hedge accounting. In order to
      qualify for hedge accounting, the company's notional amount of interest
      rate swaps and caps must be less than or equal to existing variable
      rate debt. Amounts payable or receivable in respect of these agreements
      are recognized as adjustments to interest expense over the period of
      the contracts. The cash flows from interest rate swaps and gains and
      losses arising on terminations of interest rate swaps are recognized as
      returns on investments and servicing of finance. Where associated debt
      is not retired in conjunction with the termination of an interest swap,
      gains and losses are deferred and are amortized to interest expense
      over the remaining life of the associated debt to the extent that such
      debt remains outstanding.

      Interest rate caps
      Interest rate caps are used to limit interest rate exposures. The
      premiums on these contracts are amortized over the period of the
      contracts and are disclosed as interest expense.

      Forward contracts
      The company enters into forward contracts for the purchase and/or sale
      of foreign currencies in order to manage its exposure to fluctuations
      in currency rates. Unrealized gains and losses on contracts are not
      accounted for until the maturity of the contract. The cash flows from
      forward purchase contracts are classified in a manner consistent with
      the underlying nature of the hedged transaction.

      Premiums and discounts
      Premiums and discounts arising on the early repayment of borrowings are
      written off to the profit and loss account as incurred.

      Contracts for Differences (CfDs)
      The company uses CfDs to minimize exposure to Pool price variations.
      The cost or the income attributable to CfDs is recorded in the
      accounting records when settlement is made. Where delivery under the
      CfD has taken place prior to the period end, adjustments are made to
      account for the known variances between the contract strike price and
      the Pool price on the date of delivery.

      Goodwill
      Purchased goodwill represents the excess of the fair value of the
      purchase consideration over the fair value of the net assets acquired.
      Goodwill arising from the purchase of trading entities in accounting
      periods prior to March 31, 1998 has been written off on acquisition
      against the merger reserve to reduce it to zero and thereafter has been
      offset against the profit and loss reserve. On disposal of trading
      entities, the goodwill previously included in reserves is charged to
      the profit and loss account matched by an equal credit to reserves.
      Goodwill arising on acquisitions since April 1, 1998 is capitalized and
      amortized through the profit and loss account over its useful economic
      life.

      Tangible fixed assets
      Accounting for non-water infrastructure assets
      Tangible fixed assets are stated at cost or valuation and are
      depreciated on the straight line method over their estimated
      operational lives. Tangible fixed assets include capitalized employee
      costs which are directly attributable to construction of fixed assets.
      Land is not depreciated. The main depreciation periods used by the
      group are as set out below:

</TABLE>

      Infrastructure accounting
      Water infrastructure assets, being mains and sewers, reservoirs, dams,
      sludge pipelines and sea outfalls comprise a network of systems.
      Expenditure on water infrastructure assets relating to increases in
      capacity or enhancement of the network and on maintaining the operating
      capability of the network in accordance with defined standards of
      service is treated as an addition to fixed assets.

      The depreciation charge for water infrastructure assets is the
      estimated level of annualised expenditure required to maintain the
      operating capability of the network and is based on the asset
      management plan agreed with the water industry regulator as part of the
      price regulation process.

      The asset management plan is developed from historical experience
      combined with a rolling program of reviews of the condition of the
      infrastructure assets.

      The method of accounting for water infrastructure renewals has been
      revised following the introduction of FRS 12 "Provisions, contingent
      liabilities and contingent assets' and the infrastructure renewals
      accounting basis as set out in FRS 15 "Tangible fixed assets'. As a
      consequence the balance sheet has been restated to take account of the
      necessary changes since the date of acquisition of Southern Water in
      August 1996. Further information is given in Note 16. The change of
      accounting policy has no effect on the profit and loss account other
      than to reclassify the renewals charge as depreciation.

      Comparative figures have been restated in the cash flow statement, the
      balance sheet, Notes 2, 9(b), 10, 16, 19 and 34.

      Leased assets
      As lessee
      Assets leased under finance leases are capitalized and depreciated in
      line with the group depreciation policy. The interest element of the
      finance lease repayments is charged to the profit and loss account in
      proportion to the balance of the capital repayments outstanding.
      Rentals payable under operating leases are charged to the profit and
      loss account as incurred.

      As lessor
      Rentals receivable under finance leases are allocated to accounting
      periods to give a constant periodic rate of return on the net cash
      investment in the lease in each period. The amounts due from lessees
      under finance leases are recorded in the balance sheet as a debtor at
      the amount of the net investment in the lease after making provisions
      for bad and doubtful rentals receivable.

      Property clawback
      A debenture has been issued to the Secretary of State for Scotland
      which entitles HM Government to a proportion of any property gain
      (above certain thresholds and after deducting an amount representing
      corporation tax thereon) accruing or treated as accruing to
      ScottishPower as a result of the disposal or deemed disposal after
      March 31, 1991 of certain property held at March 31, 1990. These
      arrangements last until March 31, 2001.

<PAGE>


      In the case of Manweb, if properties are disposed of, or are deemed to
      have been disposed of prior to April 1, 2000, a part of the gain over
      the value at March 31, 1990 (as adjusted for inflation and taxation)
      will become payable to HM Government.

      In the case of both companies, a liability for clawback in respect of
      property disposals is recognized only when an actual or a deemed
      disposal occurs.

      Investments
      Investments in subsidiary and associated undertakings and joint
      ventures are stated in the balance sheet of the parent company at cost,
      or nominal value of shares issued as consideration where applicable,
      less provision for any impairment in value. The group profit and loss
      account includes the group's share of the operating profits less
      losses, net interest charge and taxation of associated undertakings and
      joint ventures. The group balance sheet includes the investment in
      associated undertakings and joint ventures at the group's share of
      their net assets. Other fixed asset investments are carried at cost
      less provision for diminution in value.

      Stocks
      Stocks are valued at the lower of cost and net realizable value.

      Foreign currencies
      Transactions in foreign currencies are recorded at the rate ruling at
      the date of the transaction. At the year end, monetary assets and
      liabilities denominated in foreign currencies are translated at the
      rate of exchange ruling at the balance sheet date or, where applicable,
      at the contracted rate. Any gain or loss arising on the restatement of
      such balances is taken to the profit and loss account.

      Taxation
      The charge for ordinary taxation is based on the profits for the year
      and takes into account deferred taxation, using the liability method,
      in respect of timing differences to the extent that it is probable that
      a liability will crystallize in the foreseeable future. Such timing
      differences arise primarily from the differing treatment for taxation
      and accounting purposes of provisions and the depreciation of fixed
      assets.

      Pensions
      The group provides pension benefits through both defined benefit and
      defined contribution arrangements. The regular cost of providing
      pensions and related benefits and any variations from regular cost
      arising from the actuarial valuations for defined benefit schemes are
      charged to the profit and loss account over the expected remaining
      service lives of current employees following consultations with the
      actuary. Any difference between the charge to the profit and loss
      account and the actual contributions paid to the Pension Schemes is
      included as an asset or liability in the balance sheet. Payments to the
      defined contribution schemes are charged against profits as incurred.

      Grants and contributions
      Capital grants and customer contributions in respect of additions to
      non-water infrastructure fixed assets are treated as deferred income
      and released to the profit and loss account over the estimated
      operational lives of the related assets. Grants and contributions
      receivable relating to water infrastructure assets have been deducted
      from the cost or valuation of those assets. While this treatment is in
      accordance with Statement of Standard Accounting Practice (SSAP) 4, it
      is not in accordance with the Companies Act 1985. The Act requires
      capital grants and contributions to be shown as deferred income rather
      than offset against the cost or valuation of tangible fixed assets.
      This departure from the requirements of the Act is, in the opinion of
      the directors, necessary for the Accounts to give a true and fair view
      as, while provision is made for depreciation of water infrastructure
      assets, these assets do not have determinable finite lives and
      therefore no basis exists on which to recognise grants and
      contributions as deferred income. The effect of this treatment on the
      value of tangible fixed assets is disclosed in Note 16.

      Own shares held under trust
      The amount recorded in the balance sheet for shares in the company
      purchased for employee sharesave schemes represents the amounts
      receivable from option holders on exercise of the options.

      Long Term Incentive Plan
      Shares in the company purchased for the Long Term Incentive Plan are
      held under trust and are recorded within investments in the balance
      sheet at cost. The cost of awards made by the trust under the Long Term
      Incentive Plan, being the difference between the fair value of the
      shares and the option price at the date of grant, is taken to the
      profit and loss account on a straight line basis over the period in
      which performance is measured.

      Business segment definitions
      ScottishPower defines business segments based on a combination of
      factors, principally differences in products and services and the
      regulatory environment in which the businesses operate.

      The business segments of the group are defined as follows:

      Generation Wholesale
      The generation of electricity from the company's own power stations,
      the purchase of external supplies of energy for sale to other business
      segments of the company and the sale of electricity to other public
      electricity suppliers and to the Pool in England and Wales.

      Power Systems
      The transmission and distribution businesses in Scotland and,
      specifically, the transportation of units of electricity from the power
      stations through the transmission and distribution networks to
      customers in Scotland and to customers in England and Wales through the
      Anglo-Scottish Interconnector.

      Energy Supply
      The sale of energy to customers, together with related billing and
      collection activities for customers contracted to Scottish Power plc.

      Manweb
      The distribution and supply businesses operating in Merseyside and
      North Wales and, specifically, the purchase, distribution and sale of
      electricity to customers, together with related billing and collection
      activities within that licensed area.

      Southern Water
      The provision of water and wastewater services in the south-east of
      England, together with related billing and collection activities.

      ScottishTelecom
      The provision of telecommunications services, Internet access and
      information services to national corporates, small and medium-sized
      enterprises and residential customers.

      Other
      The retailing and servicing of domestic electrical goods and home
      entertainment appliances, the provision of electrical contracting,
      consultancy and corporate services, gas trading and the businesses of
      the company's other subsidiary and associated undertakings.

      In the segmental analyses on pages F-9 and F-17, all material
      activities are derived from continuing operations in the U.K.

<PAGE>


      Revenue cost definitions
      Cost of sales
      The cost of sales for the group, excluding Southern Water, reflect the
      direct costs of the generation and purchase of electricity, the
      purchase of natural gas, retail trading, telecommunication services,
      electrical contracting and consultancy services. For Southern Water,
      cost of sales represents the cost of extracting water from underground
      and raw water surface reservoirs and of its treatment and supply to
      customers and the subsequent collection of wastewater and its treatment
      and disposal.

      Transmission and distribution costs
      The cost of transmitting units of electricity from the power stations
      through the transmission and distribution networks to customers. It
      includes the costs of metering, billing and debt collection. This
      heading is considered more appropriate to the electricity industry than
      the standard Companies Act heading of distribution costs.

      Administrative expenses
      The indirect costs of businesses, the costs of centralised services and
      rates.

      Other definitions
      Company or ScottishPower
      Scottish Power plc.

      Group
      Scottish Power plc and its consolidated subsidiaries.

      Associated undertakings
      Entities in which the company holds a long-term participating interest
      and exercises significant influence.

      Joint ventures
      Entities in which the company holds a long-term interest and shares
      control with another company external to the group.

      Subsidiary undertakings
      Entities in which the company holds a long-term controlling interest.

      (i) In fiscal 1999, ScottishPower adopted FAS 131, Disclosures about
      Segments of an Enterprise and Related Information. This standard
      establishes a new framework for segment reporting where the management
      reporting structure forms the basis of external disclosures. The
      accounting policies of the segments are the same as those described in
      the "Accounting Policies and Definitions' on pages F-1 to F-6.

      (ii) The 1997 figures for Southern Water cover the post-acquisition
      period from August 6, 1996 to March 31, 1997.

      (iii) The Generation Wholesale segment previously included sales from
      gas trading activities which are now reported in the Other business
      segment. Total turnover for the Generation Wholesale segment for 1998
      included (Pounds)100.5 million and for 1997 (Pounds)30.0 million of gas
      trading sales of which (Pounds)82.4 million and (Pounds)16.1 million
      related to internal sales.

      (iv) The ScottishTelecom business segment and the Other business
      segment were previously combined as the Developing businesses and
      ancillary services segment. The ScottishTelecom business segment has
      been separately identified due to its increased significance to the
      group. Prior year figures have been restated accordingly.

      (v) Within the ScottishTelecom business segment, Demon Internet Limited
      contributed external turnover of (Pounds)48.5 million and operating
      profit before goodwill amortization of (Pounds)12.4 million since its
      acquisition on May 1, 1998. The turnover and operating profit of
      Watermark Games Limited are not material to the ScottishTelecom
      business segment.

      (vi) Operating profit for Manweb comprises distribution operating
      profit of (Pounds)91.9 million (1998 (Pounds)95.4 million, 1997
      (Pounds)112.0 million) and supply and other operating profit of
      (Pounds)33.3 million (1998 (Pounds)35.9 million, 1997 (Pounds)23.0
      million).

      Adjusted earnings per share has been presented in addition to earnings
      per share calculated in accordance with FRS 14 in order that more
      meaningful comparisons of financial performance can be made. The
      figures for the years ended March 31, 1997 and March 31, 1998 do not
      contain goodwill amortization as the group has adopted the transitional
      provisions of FRS 10 and only capitalized goodwill arising on
      acquisitions since April 1, 1998.

      The adjustments relate to alignment of fixed asset capitalization
      policies and recognition of unrecorded liabilities.

      The acquisition method of accounting has been adopted in respect of
      both acquisitions. The results of these companies for the periods
      before and since acquisition are not material to the group.

      Goodwill on these acquisitions is being amortized over 15 years. The
      directors have estimated the useful economic life of goodwill acquired
      after assessment of trade barriers and technology and rate of market
      change.

      (i) The Manweb distribution and Southern Water operational assets were
      revalued by the directors on September 30, 1997 by assessing discounted
      estimated future cash flows. These revaluations followed the imposition
      of the windfall tax which reduced significantly uncertainties taken
      into account in assessing the values ascribed to these assets at their
      respective dates of acquisition. In view of the isolated nature of the
      reason for the revaluation, the valuations have not been and will not
      be updated, as permitted under the transitional provisions of FRS 15
      "Tangible fixed assets'. The net book value of tangible fixed assets
      included at valuation at March 31, 1999 was (Pounds)2,311.2 million
      (1998 (Pounds)2,373.9 million).
      (ii) Interest on the funding attributable to major capital projects was
      capitalized during the year at a rate of 9% (1998 10%).
      (iii) Assets not subject to depreciation are land. Land and buildings
      held by the group and company are predominantly freehold.
      (iv) The opening balances in respect of cost or valuation and
      depreciation of water infrastructure assets have been restated as a
      result of implementing the infrastructure renewals accounting basis as
      set out in FRS 15 "Tangible fixed assets'. The effect of the adjustment
      has been to increase tangible fixed assets and reduce prepayments and
      accrued income by (Pounds)15.7 million (1998 (Pounds)5.4 million).
      There is no effect on the profit and loss account other than to
      reclassify the renewals charge as depreciation.
      (v) The historical cost of fully depreciated tangible fixed assets
      still in use was (Pounds)241.2 million (1998 (Pounds)234.6 million).

      All amounts in the analysis above are payable in sterling and take into
      account the effect of interest rate swaps and caps and currency swaps.
      Floating rate borrowings bear interest at rates based on LIBOR.
      Based on the floating rate net debt of (Pounds)384.0 million at March
      31, 1999 (1998 (Pounds)199.5 million), a 1% change in interest rates
      would result in a (Pounds)3.8 million change in profit before tax for
      the year (1998 (Pounds)2.0 million change).

      (d) Borrowing facilities
      The group has the following undrawn committed borrowing facilities at
      March 31 in respect of which all conditions precedent have been met.
      The (Pounds)600 million committed facility that expires within one year
      has a term out option that allows the facility to be extended until
      June 2001.

      (e) Financial instruments and risk management

      (i) Overview
      The main financial risks faced by the group are exchange rate risk,
      interest rate risk and Pool price risk. The Board has reviewed and
      agreed policies for managing each of these risks as summarized below.
      The use of all classes of financial instruments to manage these risks
      has been approved by the Board. The group treasury, which is authorized
      to conduct the day-to-day treasury activities of the group, reports at
      least annually to the Board and is subject to examination by internal
      audit. The Energy Trading Center, which is authorized to carry out
      activities to manage the group's Pool price risk, reports monthly to a
      risk committee which is comprised of two executive directors and an
      external consultant. The Energy Trading Center also reports at least
      annually to the Board and is subject to examination by internal audit.

      (ii) Treasury strategy
      The group treasury aims to obtain finance at the lowest possible cost
      by borrowing in the global financial markets in a range of different
      instruments. Debt is sourced in a range of different currencies,
      maturities and interest terms, primarily by means of a US$4,000 million
      debt issuance program and a US$2,000 million euro-commercial paper
      program. These are supported by committed and uncommitted bank
      facilities and funds from the European Investment Bank.

      Treasury strategy is regularly reviewed by the Board, which sets
      parameters for the maturity and interest profiles of the group's debt.
      Borrowings sourced in currencies other than sterling are swapped back
      to sterling by means of cross currency swaps and the approved balance
      between fixed and floating rate debt is achieved by means of interest
      rate swaps and caps. This means that the group has a substantial
      portfolio of derivative contracts which help to increase flexibility
      and reduce cost. The credit risk associated with such derivative
      contracts is approved by the Board and is limited by reference to
      credit ratings published by the international credit rating agencies.
      These limits also apply to any credit risk associated with cash
      deposits. The group does not believe that it is exposed to any material
      concentration of credit risk.

      All derivative contracts are undertaken as hedging arrangements;
      speculative trades are not undertaken. In view of the long life of some
      of these contracts the effect of marking them to market can give rise
      to substantial present value opportunity profits or losses as is the
      case for medium and long-term primary instruments. These present value
      opportunity profits and losses are not recognized in the profit and
      loss account in the current year since they relate to future periods
      and are matched by cash flows in those periods.

      (iii) Energy trading strategy
      Almost all electricity generated in England and Wales must be sold to
      the Pool, and electricity suppliers including Manweb must likewise buy
      electricity from the Pool for resale to their customers. The Pool was
      established at the time of privatization in England and Wales for bulk
      electricity trading between generators and suppliers. ScottishPower
      participates in the Pool by exporting/importing electricity to/from
      England and Wales via the Interconnector. The Pool is operated under a
      Pooling and Settlement Agreement to which all licensed generators and
      suppliers of electricity in Great Britain are party.

      The group has procedures in place to minimize exposure to Pool price
      variations, that is, the possibility that a change in Pool prices will
      reduce the proceeds of electricity sold to the Pool or increase the
      cost of electricity purchased from the Pool. These procedures involve
      ScottishPower and its subsidiary Manweb entering into contracts for
      differences (CfDs). In general, the terms of CfDs are such that
      contracts are settled monthly (or more frequently) in arrears by
      reference to actual half hourly Pool prices.

      During the year ended March 31, 1999, more than 90% of the group's
      exposure to Pool prices was hedged in this way. Cover is built up
      throughout the year and at March 31, 1999 a significant proportion of
      the group's exposure to Pool price variations for the following
      financial year is covered.

      The group has also entered into some longer term (in excess of one
      year) arrangements to protect against the volatility of Pool prices.
      These arrangements have the potential to be increased as the business
      grows and the time period covered will be reviewed on an ongoing basis.

      These CfDs involve a degree of credit risk. This is the risk that the
      counterparty to the CfD defaults on settlement. The group controls
      credit risk arising from holding the CfDs through credit approvals,
      limits and monitoring procedures.

      (iv) Principal financial instruments used by the group

      Interest rate swaps
      Interest rate swaps are used mainly to convert floating rate borrowings
      to fixed rates to reduce the financial risk to the group from potential
      future increases in interest rates.

      Cross currency swaps
      Cross currency swaps are used to convert liabilities for borrowings in
      currencies other than sterling into sterling liabilities.

      Interest rate caps
      Interest rate caps are used solely to limit the group exposure to
      possible future increases in interest rates.

      Forward contracts
      The group generally hedges foreign exchange transaction exposures up to
      one year forward. Hedges are put in place using forward contracts at
      the time that the forecast exposure becomes reasonably certain. Gains
      and losses resulting from changes in exchange rates on contracts
      designated as hedges of forecast foreign exchange transactions are
      deferred and included in the measurement of the related foreign
      currency transaction in the period they occur.

      Commercial paper is issued in several different foreign currencies.
      Forward contracts are taken out solely to convert the debt to sterling
      to eliminate the financial risk to the group of currency movements. As
      at the year end, the group had outstanding forward foreign exchange
      contracts, the majority of which were for periods of three months or
      less, denominated in U.S. Dollars, Canadian Dollars, Swiss Francs,
      German Marks, and Euros.

      Contracts for differences (CfDs)
      A CfD is a contract between two parties (e.g. a generator and a public
      electricity supplier) that requires each party to either make or
      receive monthly payments over a specific term based on the difference
      between an agreed price (i.e. the bilaterally determined strike price)
      and a price that varies with a specified commodity index (i.e. the
      Pool), applied to an agreed quantity (i.e. number of kWs). The average
      duration for these contracts is approximately one year. The group's use
      of such derivative instruments relates directly to the underlying
      purchase and sale of electricity to and from the Pool.

      It is difficult to estimate the long-term level of Pool prices with
      reasonable accuracy and there is no readily identifiable market through
      which the CfDs could be realized in an exchange. However, based on
      management projections of the future prices of electricity, and
      considering the outcome under several future price scenarios, the group
      has determined that the fair value amount of CfDs, outstanding at the
      year end, is not material to the group's Accounts. The fair value
      amount is the difference between the strike price of the contract and
      the estimated Pool price for the relevant half hourly periods.

      The gross value of outstanding CfDs as at March 31, 1999 was
      (Pounds)467.8 million (1998 (Pounds)781.2 million).

</TABLE>

      The assumptions used to estimate current fair values of debt and other
      financial instruments are summarized below:

      (i) For cash, short-term deposits and short-term borrowings
      (uncommitted borrowing, commercial paper, and short-term borrowings
      under the committed facilities) the book value approximates to fair
      value because of their short maturities.
      (ii) The fair values of all quoted euro bonds are based on their
      closing clean market price converted at the spot rate of exchange as
      appropriate.
      (iii) The fair values of the sterling bond 2001 and the European
      Investment Bank loans have been calculated by discounting their future
      cash flows at market rates adjusted to reflect the redemption
      adjustments allowed under each agreement.
      (iv) The fair values of the sterling interest rate swaps and sterling
      interest rate caps have been estimated by calculating the present value
      of estimated cash flows.
      (v) The fair values of the cross currency interest rate swaps have been
      estimated by adding the present values of the two sides of each swap.
      The present value of each side of the swap is calculated by discounting
      the estimated future cash flows for that side, using the appropriate
      market discount rates for that currency in effect at the balance sheet
      date.
      (vi) The fair values of unquoted debt have been calculated by
      discounting the estimated cash flows for each instrument at the
      appropriate market discount rate in the currency of issue in effect at
      the balance sheet date.

      (g) Hedges
      The group's policy is to hedge the following exposures:
      -- interest rate risk using interest swaps, both sterling and cross
      currency, caps, collars, and forward foreign currency contracts;
      -- currency exposures on foreign denominated debt and future
      purchases/sales using currency swaps and forwards and spot foreign
      currency contracts.
      Gains and losses on instruments used for hedging are not recognized
      until the exposure that is being hedged is itself recognized.
      Unrecognized gains and losses on instruments used for hedging, and the
      movements therein, are as follows:

      22 Deferred taxation
      ------------------------------------------------------------------------
      No provision for deferred taxation is considered necessary at March 31,
      1999, since future taxation depreciation is expected to exceed
      accounting depreciation and therefore no deferred taxation liabilities
      are expected to crystallize in the foreseeable future. Total potential
      deferred liabilities computed at the future rate of corporation tax of
      30% (1998 30%) are as follows:

      (a) Special Share
      The "Special Share', which can be held only by one of the Secretaries
      of State or any other person acting on behalf of HM Government, does
      not carry rights to vote at the general or separate meetings but
      entitles the holder to attend and speak at such meetings. Written
      consent of the Special Shareholder is required before certain
      provisions of the company's Articles of Association or certain rights
      attaching to the Special Share are varied. This share shall confer no
      rights to participate in the capital or profits of the company, except
      that in a winding up the Special Shareholder shall be entitled to
      repayment in priority to the other shareholders. The Special Share is
      redeemable at par at any time by the Special Shareholder after
      consultation with the company.

      (b) Share capital issued
      The movement on the merger reserve reflects the reduction in shares
      which were to be issued following the acquisition of Southern Water plc
      in August 1996. It represented the cost to ScottishPower of
      transferring existing options over Southern Water plc shares to the
      Scottish Power plc Share Option Scheme. As these options are exercised,
      the merger reserve is reduced for the attributable cost of the option.

      (c) Profit and loss account of the company
      As permitted by Section 230 of the Companies Act 1985, the company has
      not presented its own profit and loss account. The company's profit and
      loss account was approved by the Board on May 6, 1999. The profit for
      the financial year per the Accounts of the company was (Pounds)260.5
      million (1998 (Pounds)219.1 million).

      (a) Group pension arrangements
      Following a review of the group's pension arrangements, the
      ScottishPower Pension Scheme, Manweb Pension Scheme and Southern Water
      Pension Scheme were closed to new members from December 31, 1998.

      The company has introduced two new group pension plans for new
      employees effective from January 1, 1999. The new plans are a defined
      benefit plan and a defined contribution plan. The defined benefit plan
      has an initial employer's contribution of 10% of pensionable salary and
      the employer's contributions to the defined contribution plan vary,
      dependent on age, between 3-5%. The pension charge in respect of these
      schemes since their introduction is (Pounds)30,000.

      (b) ScottishPower
      The company operates a funded pension scheme providing defined benefits
      based on final pensionable salary for eligible employees of the
      company. The assets of the Scheme are held separately from those of the
      company in a separate trustee administered fund. The pension charge for
      the year is based on the advice of the Scheme's independent qualified
      actuary. The prepayment included in the balance sheet represents the
      accumulated excess of the actual contributions paid to the Scheme over
      the pension accounting charge. The outcome of the valuation mentioned
      in the table above resulted in the accounting rate used for the
      calculation of the 1998-99 pension charge remaining at 4.8% of
      pensionable salaries.

      (c) Manweb
      Most of the Manweb employees are entitled to join the Electricity
      Supply Pension Scheme which provides pension and other related benefits
      based on final pensionable pay to employees throughout the Electricity
      Supply Industry in England and Wales. The assets are held in a separate
      trustee administered fund. The pension charge for the year, of 12% of
      pensionable salaries, is based on the advice of the Scheme's
      independent qualified actuary.

      (d) Southern Water
      The Southern Water group operates a number of pension schemes. The
      Scheme details above relate to the principal defined benefit scheme
      which covers the majority of the Southern Water employees. The assets
      are held in a separate trustee administered fund. Southern Water's
      other schemes are not material to the group. The pension charge for the
      year, of 12.8% of pensionable salaries, is based on the advice of the
      scheme's independent qualified actuary.

      29 Contingent liabilities
      ------------------------------------------------------------------------
      (a) The group has contingent liabilities under performance bonds and
      actual and potential claims, none of which, in the opinion of the
      directors, is material to the group.

      (b) The company has guaranteed the overdrafts of three subsidiary
      undertakings up to an amount of (Pounds)0.7 million (1998 one
      subsidiary undertaking for (Pounds)0.5 million).

      (c) The company has guaranteed Manweb's liabilities to the Pool in
      England and Wales. At March 31, 1999 these liabilities were
      (Pounds)30.9 million (1998 (Pounds)37.4 million).

      (d) Under the terms of the merger agreement between ScottishPower and
      PacifiCorp dated December 6, 1998 (as amended), if the merger agreement
      is terminated by PacifiCorp following a change in control of
      ScottishPower, other than through a Scheme of Arrangement under Section
      425 of the Companies Act 1985, ScottishPower would be required to pay
      PacifiCorp a termination fee of US$250 million.

      If the merger agreement is terminated by ScottishPower due to the
      failure to obtain the requisite vote of its shareholders and the
      termination fee described above is not payable, ScottishPower would be
      required to pay PacifiCorp US$10 million if the merger agreement is
      approved by the PacifiCorp shareholders.

      32 Employee Share Schemes
      ------------------------------------------------------------------------
      The group has three types of share scheme for employees. Options have
      been granted and awards made to eligible employees to subscribe for
      ordinary shares in Scottish Power plc in accordance with the rules of
      each scheme. The ScottishPower and Southern Water Sharesave Schemes are
      savings related and under normal circumstances share options are
      exercisable on completion of a three, five or seven year save-as-you-
      earn contract as appropriate. The Executive Share Option Scheme applied
      to executive directors and certain senior managers. However, this
      Scheme has been replaced with the Long Term Incentive Plan and,
      although it will not affect options already granted, this plan
      supersedes executive share options. Options granted under the Long Term
      Incentive Plan will vest only if the Remuneration Committee is
      satisfied that certain performance measures related to the sustained
      underlying financial performance of the group and improvements in
      customer service standards are achieved over a period of three
      financial years commencing with the financial year preceding the date
      an award is made.

      All options are exercisable over Scottish Power plc shares. Where
      reference is made to Southern Water, this is to identify the Sharesave
      Scheme under which the options over Scottish Power plc shares have been
      granted. The exercise prices of options granted prior to the rights
      issue on August 30, 1996 were adjusted to reflect the bonus element
      inherent in the rights issue.

      For the Southern Water Sharesave Scheme, the date of grant refers to
      the date the original Southern Water share options were granted. These
      options were exchanged for options over ScottishPower shares following
      acquisition in 1996.

      (i) The accrued entitlement of the highest paid director (Mr Robinson)
      was (Pounds)180,080 (1998 (Pounds)141,348, 1997 (Pounds)101,762).
      (ii) The pension entitlement shown is that which would be paid annually
      on retirement based on service to the end of the year assuming normal
      retirement at age 63. Members of the scheme have the option to pay
      additional voluntary contributions; neither the contributions nor the
      resulting benefits are included in the above table.
      (iii) Executives who joined the company on or after June 1, 1989 are
      subject to the earnings cap introduced in the Finance Act 1989. Pension
      entitlements which cannot be provided through the company's approved
      schemes due to the earnings cap are provided through unapproved pension
      arrangements. The pension benefits disclosed above include approved and
      unapproved pension arrangements.
      (iv) The increase in accrued pension during the year allows for an
      increase in inflation of RPI as measured at December 1998 (2.8%) except
      in the case of Mr. Kinski who left service on April 19, 1998.
      (v) The transfer value has been calculated on the basis of actuarial
      advice in accordance with Actuarial Guidance Note GN11, less directors'
      contributions.
      (vi) Transferred in benefits represent pension rights accrued in
      respect of previous employments.

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

      Notes

      (i) The market price of the shares at March 31, 1999 was 540.0p and the
      range during 1998-99 was 521.0p to 675.0p.

      (ii) The Long Term Incentive Plan supersedes the Executive Share Option
      Scheme, and annual awards to acquire shares in ScottishPower at nil or
      nominal cost are made to the plan participants up to a maximum value
      equal to 60% of base salary. The award will vest only if the
      Remuneration Committee is satisfied that certain performance measures
      related to the sustained underlying financial performance of the
      company and improvements in certain OFFER published Customer Service
      Standards and OFWAT published levels of service (in the case of awards
      granted in 1997 and 1998) are achieved over a period of three financial
      years commencing with the financial year preceding the date an award is
      made. Assuming that such targets have been achieved, the number of
      shares that can be acquired will be dependent upon how the company
      ranks in terms of its total shareholder return performance over a three
      year period, in comparison to the constituent companies of the FTSE 100
      Index and the electricity and water sectors. A percentage of each half
      of the award will vest depending upon the company's ranking within each
      of the relevant comparator groups. The plan participant may acquire the
      shares in respect of the percentage of the award which has vested at
      any time after the fourth year up to the seventh year after the grant
      of the award. No dividends accrue to participants prior to vesting.

      (iii) The option price of executive share options was based on the
      middle-market share price on the day immediately preceding the date of
      grant. For Sharesave options, the option price is calculated in the
      same way at the date of invitation and discounted by 20% in accordance
      with the Inland Revenue rules for such schemes.

      (iv) The options initially granted to each executive director under the
      Executive Share Option Scheme were based on a multiple of four times
      salary in respect of the Chief Executive, Mr Robinson, and three times
      in respect of the other executive directors, which is in accordance
      with the limits set out in current guidelines. Subsequent grant of
      options were made to reflect increases in directors' basic salary
      levels, following periodic review by the Remuneration Committee of the
      performance of the company and the executive directors individually.
      Executive options are normally exercisable in a manner which does not
      attract an income tax liability provided that exercise occurs between
      three and ten years after the date of grant and at least three years
      have elapsed from the date of the last "tax relieved' exercise. Total
      gains made on exercise of directors' share options during the year were
      (Pounds)592,966 (1998 (Pounds)424,097, 1997 (Pounds)16,979).

      (v) The number of options granted to a director under the Sharesave
      Scheme is calculated by reference to the total amount which the
      director agrees to save for a period of three or five years under an
      Inland Revenue approved savings contract, subject to a current maximum
      of (Pounds)250 per month. Options under the Sharesave Scheme are,
      subject to a few exceptions, exercisable within a period of six months
      from the date of completion of the savings contract.

</TABLE>

      (i) Goodwill and business combinations
      Goodwill
      Under U.K. GAAP, goodwill arising from the purchase of operating
      entities before March 31, 1998 has been written off directly against
      the merger reserve to reduce the merger reserve to zero and thereafter
      has been offset against the profit and loss reserve. Goodwill arising
      on acquisitions after March 31, 1998 is capitalized and amortized
      through the income statement over its useful economic life. Under U.S.
      GAAP, goodwill arising from the purchase of operating entities should
      be held as an intangible asset in the balance sheet and amortized over
      its expected useful life.

      The goodwill adjustment is made to recognize goodwill previously
      written off to reserves under U.K. GAAP, as an intangible asset under
      U.S. GAAP.

      This goodwill, which is capitalized under U.S. GAAP, is then amortized
      on a straight line basis over its useful economic life of 40 years with
      the effect being a reduction in profit reflecting the amortization
      charge for the period.

<PAGE>

      Note 34 continued
      ------------------------------------------------------------------------

      Business combinations
      In addition to re-instating the goodwill calculated under U.K. GAAP as
      described above, goodwill must also be recalculated in accordance with
      U.S. GAAP. This is required due to differences between U.K. GAAP and
      U.S. GAAP in the determination of acquisition price and valuation of
      assets and liabilities at the acquisition date. The adjustment referred
      to as business combinations reflects principally the impact of
      recalculating the goodwill arising on the acquisitions of Manweb and
      Southern Water under U.S. GAAP.

      (ii) Deferred taxation
      Under U.K. GAAP, provision for deferred tax is only required to the
      extent that it is probable that a taxation liability or asset will
      crystallize, in the foreseeable future, as a result of timing
      differences between taxable profit and accounting profit. Provision is
      made at known rates of tax.

      Under U.S. GAAP, full provision for deferred tax is required to the
      extent that accounting profit differs from taxable profit due to
      temporary timing differences. Provision is made at future enacted
      rates.

      The item "effect of U.S. GAAP adjustments' reflects the additional
      impact of making full provision for deferred tax in respect of
      adjustments made in restating the balance sheet to U.S. GAAP.

      The item "effect of differences in methodology' reflects the impact of
      making full provision for deferred tax.

      (iii) Pension costs
       The fundamental differences between U.K. GAAP and U.S. GAAP are as
       follows:
       (a) Under U.K. GAAP, the annual pension charge is determined so that it
       is a substantially level percentage of the current and expected future
       payroll.
       Under U.S. GAAP, the aim is to accrue the cost of providing pension
       benefits in the year in which the employee provides the related service.
       (b) Under U.K. GAAP, pension liabilities are usually discounted using an
       interest rate that represents the expected long-term return on plan
       assets. Under
       U.S. GAAP, pension liabilities are discounted using the current rates at
       which the pension liability could be settled.
       (c) Under U.K. GAAP, variations from plan can be aggregated and
       amortized over the remaining employee service lives. Under U.S. GAAP,
       variations from
       plan must be amortized separately over remaining service lives.
       (d) Under U.K. GAAP, alternative bases can be used to value plan assets.
       Under U.S. GAAP, plan assets should be valued at market or at market
       related values.

      (iv) Revaluation of fixed assets
      The revaluation of Manweb distribution assets and Southern Water
      operational assets is not permitted under U.S. GAAP. Accordingly, the
      reconciliation restates fixed assets to historical cost and the
      depreciation charge has been adjusted. Refer to Note 16 (i) for further
      information relating to the fixed assets revaluation.

      (v) Comprehensive income
      As of April 1, 1998 ScottishPower adopted FAS 130, Reporting
      Comprehensive Income. FAS 130 established new rules for the reporting
      and display of comprehensive income and its components; however, the
      adoption of this statement has no impact on ScottishPower's net income
      or shareholders' equity under U.S. GAAP.

      (vi) Ordinary dividends
      Under U.K. GAAP, final ordinary dividends are recognized in the
      financial year in respect of which they are recommended by the Board of
      Directors for approval by shareholders. Under U.S. GAAP, such dividends
      are not recognized until they are formally declared by the Board of
      Directors.

      (vii) ESOP shares held in trust
      Under U.K. GAAP, shares held by an Employee Share Ownership Plan
      ("ESOP') are recorded as fixed asset investments at cost less amounts
      written off. Under U.S. GAAP, shares held in trust are recorded at cost
      in the balance sheet as a deduction from shareholders' funds. No
      dividends have been paid on the shares held by the ScottishPower ESOP
      and future dividends have been waived.

      (viii) Earnings per share
      Under U.K. GAAP, earnings per share is calculated by dividing the net
      profit or loss for the period by the weighted average number of shares
      (for basic and diluted number of shares) outstanding for the period.
      U.K. GAAP permits the presentation of more than one measure of earnings
      per share provided that all such measures are clearly explained and are
      given equal prominence on the face of the income statement.

      Under U.S. GAAP, earnings per share is calculated by dividing earnings
      from continuing operations, excluding extraordinary items, by the
      weighted average number of shares (for basic and diluted number of
      shares) outstanding for the period. U.S. GAAP permits only one measure
      of earnings per share as a performance measure.

      (a) Earnings per ordinary share have been calculated by dividing the
      profit for the financial year under U.S. GAAP by the weighted average
      number of ordinary shares in issue during the financial year, based on
      the following information:

       Profit for the financial year under U.S. GAAP
       ((Pounds) million)                               455.0     129.8   352.9
       Basic weighted average share capital (number
       of shares, millions)                           1,185.2   1,180.1 1,104.9
       Diluted weighted average share capital
       (number of shares, millions)                   1,197.2   1,191.9 1,116.0
      -------------------------------------------------------------------------
</TABLE>

      The difference between the basic and the diluted weighted average share
      capital is wholly attributable to outstanding share options.

      (b) As permitted under U.K. GAAP, earnings per share have been
      presented including and excluding the impact of the windfall tax and
      goodwill amortization, to provide an additional measure of underlying
      performance. In accordance with U.S. GAAP, earnings per share have been
      presented above based on U.S. GAAP earnings, without adjustments for
      the impact of windfall tax and goodwill amortization. As such
      additional measures of underlying performance are not permitted under
      U.S. GAAP, the inclusion of windfall tax in the determination of
      earnings for the purpose of computation of earnings per share in
      accordance with U.S. GAAP decreased earnings by (Pounds)317.0 million
      or 26.86 pence per share for the year ended March 31, 1998. The
      inclusion on goodwill amortization decreased earnings by (Pounds)31.2
      million or 2.63 pence per share for the year ended March 31, 1999, by
      (Pounds)29.8 million or 2.53 pence per share for the year ended March
      31, 1998 and by (Pounds)23.7 million or 2.14 pence per share for the
      year ended March 31, 1997.

      Consolidated statement of Cash Flows
      The consolidated statement of cash flows prepared in accordance with
      FRS 1 (Revised) presents substantially the same information as that
      required under U.S. GAAP. Under U.S. GAAP, however, there are certain
      differences from U.K. GAAP with regard to the classification of items
      within the cash flow statement and with regard to the definition of
      cash and cash equivalents.

      Under U.K. GAAP, cash flows are presented separately for operating
      activities, dividends received from associates and joint ventures,
      returns on investments and servicing of finance, taxation, capital
      expenditure and financial investment, acquisition and disposals, equity
      dividends paid, management of liquid resources, and financing. Under
      U.S. GAAP, only three categories of cash flow activity are reported;
      operating activities, investing activities and financing activities.
      Cash flows from dividends received from associates and joint ventures,
      returns on investments and servicing of finance and taxation would be
      included as operating activities under U.S. GAAP. Equity dividends paid
      would be included under financing activities under U.S. GAAP.

      Under U.S. GAAP, cash and cash equivalents are not offset by bank
      overdrafts repayable within twenty four hours from the date of the
      advance, as is the case under U.K. GAAP and instead such bank
      overdrafts are classified within financing activities.

      The consolidated cash flow statement prepared in conformity with U.K.
      GAAP is set out on page F-12. In this statement an additional measure,
      free cash flow, is included which is not an accepted measure under U.S.
      GAAP. This measure represents cash flow from operations after adjusting
      for dividends received from associates and joint ventures, returns on
      investments and servicing of finance and taxation. U.K. investors
      regard free cash flow as the money available to management annually to
      be allocated among a number of options including capital expenditure,
      payments of dividends and the financing of acquisitions.

      Set out below is a consolidated statement of cash flows under U.S. GAAP

      (a) Group profit and loss account
      For the purposes of U.S. GAAP, transmission and distribution costs
      would be included in cost of sales, and gross profit from continuing
      operations would be calculated after deducting these expenses.

      (b) Infrastructure accounting
      The group's accounting policy in respect of Southern Water's
      infrastructure assets and related maintenance and renewals expenditure,
      as set out and explained in the accounting policies, is not generally
      accepted under U.S. GAAP which requires historical cost depreciation
      accounting for these assets. The difference between the infrastructure
      renewals depreciation charge and depreciation accounting under U.S.
      GAAP is not material to profit and equity shareholders' funds.

      (c) Share option schemes
      Under U.S. GAAP, the group applies Accounting Principles Board Opinion
      No. 25 (APB 25), Accounting for Stock Issued to Employees, and related
      interpretations in accounting for its plans. Accordingly, compensation
      expense has been recognized for its variable plan (ie long term
      incentive plan). As the group applies APB 25 in accounting for its
      plans, it is permitted, under FAS 123, Accounting for Stock-Based
      Compensation, to adopt the disclosure only option in relation to its
      share option schemes. However, if the accounting provisions of the
      statement had been adopted, the effect on 1999 net earnings would have
      been immaterial (1998: immaterial, 1997: immaterial) and accordingly no
      additional disclosures have been provided.


      (d) Deferred taxation
      U.K. GAAP requires provision for deferred taxation only when it is
      expected that a liability will become payable or an asset will
      crystallize in the foreseeable future and then at the known future
      rates of tax. U.S. GAAP requires full provision for deferred taxes to
      be made using enacted future tax rates.

      The components of the estimated net deferred tax liability that would
      be recognized under U.S. GAAP are as follows:

      (e) Pensions
      As at March 31, 1999 ScottishPower had six statutorily approved defined
      benefit pension plans. One of these plans, together with a statutorily
      approved defined contribution pension plan, was established with effect
      from January 1, 1999.

      Benefits under the defined benefit plans reflect each employee's basic
      earnings, years of service and age at retirement. Funding of the
      defined benefit plans is based upon actuarially determined
      contributions, with members paying contributions at fixed rates and the
      employers meeting the balance of cost as determined by the scheme
      actuaries.

      Under the defined contribution plan, contributions are paid by the
      member and employer at a fixed rate. Benefits under the defined
      contribution plan reflect each employee's fund at retirement and the
      cost of purchasing benefits at that time.

      ScottishPower does not provide any non-pension post-retirement benefits
      for employees.

      Reconciliations of the beginning and ending balances of the projected
      pension benefit obligation and the funded status of these plans for the
      years ending March 31, 1999 and March 31, 1998 are as follows:

      (f) Joint ventures and associates
      Under U.S. GAAP, the investor's interest in the net results of joint
      ventures and associates is disclosed as a single line in the income
      statement net of interest and taxation.

      Under U.K. GAAP, the investor's interest in the turnover and results of
      a joint venture or associate are disclosed gross. The investor's share
      of the interest and taxation are disclosed separately as a component of
      the group interest and taxation lines. The directors do not regard this
      as a material classification difference and there is no impact on net
      income.

      (g) Acquisition of Southern Water
      In accordance with the disclosure requirement of the APB Opinion Number
      16 paragraphs 95 and 96, the following is included relating to the
      acquisition of Southern Water in 1996:

      In August 1996, ScottishPower acquired Southern Water, a U.K. water
      company, for a total consideration of (Pounds)1,716.5 million which
      included a share issue of (Pounds)397.9 million (including 126.4
      million shares). As part of the acquisition agreement, deferred
      contingent consideration of (Pounds)13.4 million was included and
      related to the election made by participants of the Southern Water
      Sharesave Scheme to be granted options over ScottishPower shares in
      place of options previously granted over Southern Water shares. The
      acquisition method of accounting was used and the goodwill arising on
      the acquisition was written off to reserves in the year to March 31,
      1997 in accordance with the accounting policy adopted at that time.
      Southern Water contributed operating profit, before reorganization
      costs, of (Pounds)135.6 million in the eight months from the date of
      acquisition to March 31, 1997 and operating profit of (Pounds)240.7
      million in the year ended March 31, 1998. Had the acquisition taken
      place on April 1, 1996, Southern Water would have contributed turnover
      of (Pounds)474.5 million, operating profit of (Pounds)200.0 million and
      profit after ordinary tax of (Pounds)139.3 million in the year to March
      31, 1997. For the year to March 31, 1996, Southern Water recorded
      turnover of (Pounds)424.7 million, operating profit of (Pounds)170.6
      million and profit on ordinary activities after tax of (Pounds)144.8
      million. Had the acquisition taken place on April 1, 1996, the
      contribution to earnings per share from Southern Water's operations
      would have been 12.60p in the year to March 31, 1997 and 16.20p in the
      year to March 31, 1996.

      New U.S. accounting standards adopted

      Reporting Comprehensive Income
      FAS 130: Statement of Financial Accounting Standard 130, Reporting
      Comprehensive Income. This statement was issued in June 1997 and
      establishes standards for the reporting and display of comprehensive
      income and its components. FAS 130 is effective for fiscal years
      beginning after December 15, 1997. The standard requires financial
      statements provided for earlier periods to be reclassified.

      Segmental Information
      FAS 131: Statement of Financial Accounting Standard 131, Disclosures
      About Segments of an Enterprise and Related Information. This statement
      was issued in June 1997 and establishes standards for the reporting of
      information about operating segments in financial statements issued to
      shareholders. It also establishes standards for related disclosure of
      products and services, geographic areas, and major customers. The
      information set out in Note 1 and Note 14 to the financial statements
      reflects the requirements of FAS 131.

      Employers' Disclosures about Pensions
      FAS 132: Statement of Financial Accounting Standard 132, Employers'
      Disclosures about Pensions and Other Post-retirement Benefits was
      issued in February 1998 and revises employers' disclosures about
      pensions. The information set out above reflects the requirements of
      FAS 132.

      Recent U.S. accounting pronouncements

      Accounting for Derivative Instruments and Hedging Activities
      FAS 133: Statement of Financial Accounting Standard 133, Accounting for
      Derivative Instruments and Hedging Activities has been issued and is
      effective for fiscal periods beginning after June 15, 2000 with earlier
      application permitted. This standard establishes accounting and
      reporting standards for derivative instruments and for hedging
      activities. Management is currently reviewing the standard to assess
      the impact on ScottishPower. Implementation of FAS 133 will result in
      financial instruments being included in the balance sheet and carried
      at fair market value, including hedging activities.

      Accounting for the Costs of Computer Software Developed or Obtained for
      Internal Use
      SOP 98-1: Statement of Position 98-1, Accounting for the Costs of
      Computer Software Developed or Obtained for Internal Use was issued
      during January 1998 by the American Institute of Certified Public
      Accountants (AICPA). This becomes effective for all fiscal years
      beginning after December 15, 1998 and provides guidance on when costs
      incurred for internal use computer software are and are not
      capitalized. ScottishPower does not expect adoption of SOP 98-1 to have
      a material impact on ScottishPower's financial statements.

      Accounting for Contracts Involved in Energy Trading and Risk Management
      Activities
      In December 1998 the FASB Emerging Issues Task Force (EITF) reached a
      consensus on Issue No. 98-10, Accounting for Contracts Involved in
      Energy Trading and Risk Management Activities. The guidance comes into
      effect for ScottishPower for the year ended March 31, 2000 and is
      expected to have minimal impact as the majority of ScottishPower's
      energy contracts fall outside the scope of this consensus.

      Accounting for Plant Decommissioning Costs
      The FASB is currently reviewing the utility industry's accounting
      treatment of certain plant decommissioning costs. In an exposure draft
      issued in February 1996, the FASB concluded that decommissioning costs
      should be accounted for as a liability at expected present value, with
      a corresponding asset in utility plant. The FASB expects to issue a new
      exposure draft in 1999 and ScottishPower will assess the impact at that
      time.

      Directors' Responsibilities for the Preparation of the Financial
      Statements

      The directors are required to prepare financial statements for each
      fiscal year which present fairly, in all material aspects, the
      consolidated financial position of the group at the fiscal year end and
      the consolidated results of operations and cash flows of the group for
      that period.

      The directors are also required to consider whether in preparing the
      financial statements for the fiscal years shown on pages F-1 to F-40,
      the group has used appropriate accounting policies, consistently
      applied and supported by reasonable and prudent judgments and
      estimates. They also consider whether all accounting principles which
      they consider to be applicable have been followed and ascertain whether
      it is appropriate for the financial statements to be prepared on the
      going concern basis.

      The directors are responsible for ensuring that the company keeps
      accounting records which disclose with reasonable accuracy the
      financial position of the group and which enable them to ensure that
      the financial statements comply with the U.K. Companies Act 1985. They
      are also responsible for taking such steps that are reasonably open to
      them to safeguard the assets of the group and to prevent and detect
      fraud and other irregularities.

      Report of the Independent Accountants
      To the board of directors and members of Scottish Power plc

      We have audited the consolidated balance sheets of Scottish Power plc
      as at March 31, 1999 and March 31, 1998 and the related consolidated
      statements of income, cash flows and changes in shareholders' funds for
      the years ended March 31, 1999, March 31, 1998 and March 31, 1997.
      These financial statements are the responsibility of the company's
      directors, as set out above. Our responsibility is to express an
      opinion on these financial statements based on our audits. Our
      examinations of these statements were made in accordance with auditing
      standards generally accepted in the United States and in the United
      Kingdom and, accordingly, included such tests of the accounting records
      and such other auditing procedures as we considered necessary in the
      circumstances.

      Opinion

      In our opinion the consolidated financial statements referred to above
      present fairly, in all material respects, the consolidated financial
      position of Scottish Power plc as at March 31, 1999 and March 31, 1998
      and the results of its operations and cash flows for the years ended
      March 31, 1999, March 31, 1998 and March 31, 1997 in conformity with
      accounting principles generally accepted in the United Kingdom.

      Accounting principles in the United Kingdom vary in certain specific
      respects from accounting principles generally accepted in the United
      States. Application of generally accepted accounting principles in the
      United States would have affected the determination of profit for the
      financial year and shareholders' funds as at and for the years ending
      March 31, 1999 and March 31, 1998 to the extent summarized in Note 34
      to the financial statements.

1.    This document illustrates the licence obligations which presently apply
      under the Generation, Transmission and Public Electricity Supply Licences
      held by Scottish Power plc (excluding only the schedules relating to
      transmission price restraints). The document comprises conditions
      contained in the original Licence Document granted on 28 March 1990 and
      subsequent modifications made to that Licence Document.

2.    OFFER wishes to make clear that this is not a legally binding document but
      has been produced as a working copy of Scottish Power plc's Generation,
      Transmission and PES Licences. It is hoped that this document accurately
      reflects the present Licence Document, but it is not a substitute for the
      original Licence Document and the subsequent schedules of modifications
      issued to Scottish Power plc and held by OFFER's library.

8.    The Licensee shall not be obliged pursuant to this Condition 8 to offer to
      enter into any agreement with any person if:

      (a)   to do so would be likely to involve the Licensee in breach of:

                  Licensee; or

            (ii)  the Distribution Code or the Distribution Code of any other

Condition 8A. Connection to and use of ancillary system - functions of the
Director

1.    If, after a period which appears to the Director to be reasonable for the
      purpose, the Licensee has failed to enter into an agreement with a person
      entitled or claiming to be entitled thereto pursuant to an application in
      accordance with Condition 8, the Director may, pursuant to Section 7(3) of
      the Act, on the application of such person or the Licensee, settle any
      terms of the agreement in dispute between the Licensee and the person in
      such manner as appears to the Director to be reasonable having (insofar as
      relevant) regard, in particular, to the following considerations:

      (a)   that the person should pay to the Licensee the whole or an
            appropriate proportion (as determined in accordance with paragraph 6
            of Condition 8) of the costs directly or indirectly incurred by the
            Licensee in the carrying out of any works or in providing or doing
            any other thing under the agreement in question calculated in
            accordance with the principles set out in paragraph 4 of Condition 8
            together with a reasonable rate of return on the capital represented
            by such costs;

      (b)   that the performance by the Licensee of its obligations under the
            agreement should not cause it to be in breach of any other Condition
            to which the Generation Licence is subject;

      (c)   that any methods by which the system is connected to the
            Transmission System of the Licensee or any other Transmission
            Licensee or the Distribution System of the Licensee or any other
            public electricity supplier or the system for the distribution of
            electricity of any other person authorised to supply electricity
            accords with good engineering principles and practices; and

      (d)   that the terms and conditions of agreements entered into by the
            Licensee pursuant to an application in accordance with Condition 8
            should be, so far as circumstances allow, as similar in substance
            and form as is practicable.

2.    If the person wishes to proceed on the basis of the agreement as settled
      by the Director, the Licensee shall forthwith enter into and implement

3.    If the Licensee proposes to vary the contractual terms of any agreement
      entered into pursuant to Condition 8 or this Condition in any manner
      provided for under such agreement, the Director may, at the request of the
      Licensee or other party to such agreement, settle any dispute relating to
      such variation in such manner as appears to the Director to be reasonable.

Condition 3. Prohibition of discrimination in electricity sale contracts

1.    The Licensee shall not, and shall procure that no affiliate or related
      undertaking of the Licensee shall, sell or offer to sell electricity under
      any electricity sale contract to any one relevant purchaser or person
      seeking to become a relevant purchaser on terms as to price which are
      materially more or less favourable than those on which it sells or offers
      to sell electricity under any electricity sale contract to comparable
      relevant purchasers. For these purposes, due regard shall be had to the
      circumstances of sale to such purchasers including (without limitation)
      volumes, load factors, conditions of interruptibility and the dates and

Condition 3A. Prohibition of discrimination in supply

1.    This Condition applies where the Licensee is in a dominant position in a
      market for the supply of electricity to customers at premises.

2.    Where this Condition applies the Licensee shall not supply or offer to
      supply electricity to customers in any market in which it is dominant on
      terms which are predatory.

3.    Where this Condition applies, but subject to paragraph 4, the Licensee
      (taken together with its affiliates and related undertakings) shall not,
      in supplying or offering terms for the supply of electricity to customers
      in any market in which it is dominant:

      (a)   show undue preference to any person (or class of persons) within
            such market;

      (b)   exercise undue discrimination between any persons (or classes of
            person) within such market; or

      (c)   set terms which are unduly onerous.

4.    Nothing in paragraph 3 shall prohibit the Licensee, within any area or
      class of customers (the "relevant area or class") in respect of which
      there is established competition in the supply of electricity, from
      supplying or offering to supply electricity on terms which are reasonably
      necessary to meet that competition, save that the Licensee (taken together
      with its affiliates and related undertakings) shall not, in supplying or
      offering terms for the supply of electricity:

      (a)   show undue preference to any person (or class of persons) or
            exercise undue discrimination between any persons (or classes of
            person) within the relevant area or class of customers; or


Scottish Power                          95                           August 1998
<PAGE>

      (b)   set terms in respect of any person (or class of persons) in a market
            in which the Licensee is dominant, save such persons who are within
            the relevant area or class of customers, which are unduly onerous.

5.    For the purposes of this Condition, terms are unduly onerous if the
      revenue from the supply of electricity to customers on those terms:

      (a)   significantly exceeds the costs of that supply; and

      (b)   exceeds such costs to a significantly greater degree than the
            revenue from supply to all other customers of the Licensee (and of
            its affiliates and related undertakings) within the same market
            exceeds the costs of supply to those customers.

6.    For the purposes of this Condition, a market may be defined by reference
      to a geographical area, or to a class of customer or both, save that no
      market defined by reference to Designated Customers shall comprise fewer
      than 50,000 such customers.

7.    In determining, for the purposes of this Condition, whether any persons
      constitute a class of person, due regard shall be had to the circumstances
      of supply to such persons including (without limitation) volumes, load
      factors, conditions of interruptibility, location of premises being
      supplied and date and duration of the supply contract.

8.    For the purposes of this Condition, the Director shall determine any
      question as to:

      (a)   whether any area or class of customers constitutes a market for the
            supply of electricity;

      (b)   whether the Licensee is dominant in any market for the supply of
            electricity;

      (c)   whether there is established competition in respect of the supply of
            electricity in any area or to any class of customers; and

<PAGE>

      (d)   whether any terms are predatory, having due regard to whether such
            terms:

            (i)   incorporate charges which do not reasonably cover the
                  avoidable costs incurred in consequence of supplying the
                  customers in question; and

            (ii)  are intended or are likely to restrict, distort or prevent
                  competition in the supply of electricity.

9.    The Director may determine that the Licensee is dominant in a specified
      market:

      (a)   at any time prior to this Condition coming into force; or

      (b)   having first consulted with the Licensee and such other persons as
            he considers appropriate (and having taken into account any
            representations made to him), at any time after this Condition has
            come into force,

      and where the Director does make such a determination he shall immediately
      notify the Licensee.

10.   Where the Director has notified the Licensee of his determination in
      accordance with paragraph 9 that it is dominant in a specified market, the
      provisions of paragraphs 11 to 16 shall apply in respect of that market.

11.   Where this paragraph applies the Licensee shall, prior to supplying or
      offering to supply electricity under a tariff or Designated Supply
      Contract on any new terms, give to the Director at least 28 days' notice
      in writing of its intention to supply on such terms.

12.   For the purposes of this Condition, a tariff or Designated Supply Contract
      is on "new terms" if:

      (a)   it is a form of tariff or Designated Supply Contract under which the
            Licensee has not previously supplied or offered to supply
            electricity;


Scottish Power                          97                           August 1998
<PAGE>

      (b)   it is a tariff or Designated Supply Contract in respect of which the
            Licensee is varying the terms as to price; or

      (c)   it is a tariff or Designated Supply Contract in respect of which the
            Licensee is varying any other terms in such a manner as to
            significantly affect the evaluation of that tariff or contract.

13.   Where the Licensee has given notice to the Director of its intention to
      supply on new terms it shall not supply or offer to supply electricity on
      such terms until either the period of notice given to the Director has
      expired and:

      (a)   the Director has not given or sent to the Licensee a counter-notice
            (the "counter-notice") in accordance with paragraph 14; or

      (b)   prior to the expiry of such period, the Director has informed the
            Licensee that he will not issue a counter-notice in respect of such
            terms.

14.   The Director may issue a counter-notice where, having considered the new
      terms and having had regard to the likely effects of issuing such
      counter-notice (including, but not limited to, the likely effect upon the
      business of the Licensee), he determines that further consideration is
      required to assess whether such terms are in breach of the provisions of
      this Condition.

15.   Where the Director issues a counter-notice in respect of any new terms the
      Licensee shall not supply or offer to supply electricity on such terms
      until either:

      (a)   a period of 3 months from the date of the counter-notice has
            expired; or

      (b)   prior to the expiry of such period, the Director indicates to the
            Licensee that he has no present intention of taking enforcement
            action under Section 25 of the Act in respect of such terms.

16.   Where the Director issues a counter-notice he may:

      (a)   give or send a copy of that counter-notice to any Interested Person;

      (b)   invite representations from Interested Persons as to the matters to
            which the counter-notice relates; and

      (c)   require the Licensee, within a reasonable period determined by the
            Director, to provide him with such further information relating to
            the new terms as he may specify (save that he may not by virtue of
            this paragraph require the Licensee to furnish him with information
            for the purpose of exercising his functions under Section 48 of the
            Act),

      and the Director shall take into account any representations made to him
      by the Licensee in respect of such terms.

17.   The Director may, at any time after notifying the Licensee of his
      determination in accordance with paragraph 9 that it is dominant in a
      specified market, determine that the Licensee is no longer dominant in
      that market, and where he does make such a determination:

      (a)   the Director shall immediately notify the Licensee; and

      (b)   the provisions of paragraphs 11 to 16 shall cease to apply in
            respect of the specified market.

18.   For the purposes of this Condition, any reference to the Licensee being
      dominant in a market for the supply of electricity shall be treated as a
      reference to the Licensee, taken together with its affiliates and related
      undertakings, being so dominant.

19.   In this Condition:

                                          evaluation of that supply, and shall
                                          include all terms as to price.

Condition 3B. Duration of discrimination conditions

1.    Condition 3A shall cease to have effect (in whole or in part, as the case
      may be) if the Licensee makes a disapplication request in accordance with
      this Condition and:

      (a)   the Director agrees in writing to that request; or

      (b)   the application of Condition 3A (in whole or in part) is terminated
            by notice given by the Licensee in accordance with paragraph 4 or 5
            of this Condition.

2.    A disapplication request pursuant to this Condition may be made by the
      Licensee only where the Director has notified it, in accordance with
      paragraph 9 of Condition 3A, of his determination that the Licensee is
      dominant in a specified market, and any such request shall:

      (a)   be made in writing to the Director;

      (b)   specify whether the request relates to the whole of Condition 3A or
            any part or parts thereof; and

      (c)   state the date (the "disapplication date") from which the Licensee
            wishes the specified provisions of Condition 3A to cease to have
            effect, which date shall be in accordance with paragraph 3 and not
            earlier than 12 months after the date on which the request is made.

3.    Where the Licensee was notified by the Director prior to this Condition
      coming into force of his determination that the Licensee is dominant in a
      specified market, no disapplication request made by the Licensee shall be
      effective to disapply any of the provisions of Condition 3A prior to 31
      March 2000.

4.    If the Director has not by the date which is 6 months prior to the
      disapplication date made a reference to the Monopolies Commission (under
      Section 12 of the Act) relating to the modification of Condition 3A, the
      Licensee may give to the Director a

      notice in writing terminating the application of such of the provisions of
      Condition 3A as are specified in the disapplication request with effect
      from the disapplication date or from any later date specified in the
      notice.

5.    If the Monopolies Commission reports on a reference made by the Director
      relating to the modification of Condition 3A and does not conclude that
      the disapplication of any of the provisions of that Condition (being
      provisions specified in the disapplication request) would or may be
      expected to operate against the public interest, the Licensee may within
      30 days of the publication of the report under Section 13 of the Act give
      to the Director notice in writing terminating the application of such
      provisions with effect from the disapplication date or any later date
      specified in the notice.

Condition 4. Tariffs

1.    The Licensee shall ensure that any tariffs fixed under Section 18 of the
      Act shall be so framed as separately to identify:

      (a)   the element for use of the Licensee's Transmission System in the
            Licensee's charges;

      (b)   the element for use of the Licensee's Distribution System in the
            Licensees charges; and

      (c)   the element in respect of the supply of electricity to tariff
            customers in the Licensee's charges.

2.    Where the Director considers that by reason of the complexity of any such
      tariffs fixed by the Licensee, simplified explanatory statements are
      required or expedient for the understanding of tariff customers, the
      Director may direct the Licensee to draw up such explanatory statements
      and thereafter to publish them with the tariffs to which they relate.

Condition 4A. Arrangements for informing customers on revocation of Licence

1.    The Licensee shall comply with a direction from the Director in the
      following terms where the Director:

      (a)   is, or is aware that the Secretary of State is, about to revoke a
            Licence granted to another Electricity Supplier to supply
            electricity (in this Condition known as the "First Supplier"); and

      (b)   considers that the Licensee is able to supply electricity to the
            customers of the First Supplier without significantly prejudicing
            the supplies of electricity which the Licensee makes or is
            contracted to make.

2.    The Director shall only issue a direction in accordance with paragraph 1
      when the Secretary of State or, as the case may be, the Director has
      served the First Supplier with a notice that he is revoking the First
      Supplier's Licence to supply electricity in accordance with the terms of
      the First Supplier's Licence, or such earlier date as the Director may
      agree with the First Supplier.

3.    A direction issued in accordance with paragraph 1 shall require that the
      Licensee shall, within the period specified by the Director, send a
      written notice in a form approved by the Director to each of the persons
      or premises specified or described in the direction:

      (a)   informing the customer in question that, notwithstanding any
            contract he may have with the First Supplier, the First Supplier is
            no longer supplying him with electricity and has not done so since
            the revocation took effect or, where the notice has been sent before
            the revocation has taken effect, will be no longer supplying him
            with electricity when it takes effect;

      (b)   informing the customer that the customer must from the moment the
            revocation takes effect enter into a new contract for supply with
            another

            Electricity Supplier of the customer's choice, and that he is free
            to request a supply from the Licensee; and

      (c)   setting out the terms upon which the Licensee is prepared to supply
            electricity if requested.

Condition 4B. The Programme Implementation Agreement

1.    The Licensee shall, where the Director has given it a written direction to
      do so, enter into and comply with the Programme Implementation Agreement
      established in accordance with paragraph 4.

2.    The Programme Implementation Agreement shall be concerned with matters
      relating to the effective implementation of trading and other arrangements
      between the Licensee and other Relevant Parties which, in the reasonable
      opinion of the Director following consultation with all Relevant Parties,
      are or are likely to be necessary and appropriate to provide for the
      effective and timely facilitation of competition in the supply of
      electricity.

3.    The Programme Implementation Agreement may include provisions relating to:

      (a)   the operation and management of procedures for the testing, trialing
            and integration of those systems, processes and procedures required
            to facilitate competition in the supply of electricity;

      (b)   the obligations of each of the Relevant Parties in respect of the
            procedures defined under sub-paragraph (a);

      (c)   limitations of the liability of the Licensee and of such other
            persons as are specified in the Agreement in respect of actions
            taken in connection with the Agreement;

      (d)   the provision of information as between Relevant Parties and to
            other persons specified in the Agreement;

      (e)   the determination of the specification of systems, processes and
            procedures to be tested, trialed and integrated in accordance with
            the Agreement, except in those circumstances where the Director
            considers that any of the Relevant

            Parties has entered into another agreement which adequately provides
            for such specification to be otherwise determined;

      (f)   the settling by the Director of disputes between Relevant Parties in
            relation to matters covered by the Agreement; and

      (g)   the establishment of a board (the "Implementation Board"),
            comprising appropriate persons appointed by the Director following
            consultation with the Relevant Parties, which shall:

            (i)   oversee the conduct of the Agreement;

            (ii)  advise the Director and the Relevant Parties of any matters
                  upon which they may reasonably seek advice in relation to
                  matters covered by the Agreement, including the operation and
                  management of procedures established under the Agreement; and

            (iii) undertake such other functions as in the reasonable opinion of
                  the Director are necessary to provide for the effective and
                  timely facilitation of competition in electricity supply.

4.    The Programme Implementation Agreement shall be that established by
      agreement between the Relevant Parties with the approval of the Director
      or, where the Relevant Parties cannot agree (or where in the opinion of
      the Director such agreement is unlikely to be reached within a reasonable
      period) and where:

      (a)   the Director has sent to each of the Relevant Parties a notice (the
            "proposals notice") setting out his own proposals in relation to the
            content of the Programme Implementation Agreement; and

      (b)   following consideration of any comments received from any of the
            Relevant Parties within 21 days of the issue of the proposals
            notice, and having made such changes to his proposals as the
            Director considers appropriate, the


Scottish Power                          107                          August 1998
<PAGE>

            Director has given to each of the Relevant Parties a notice setting
            out his final proposals (the "confirmation notice"),

      the Programme Implementation Agreement shall, unless within 7 days of the
      issue of the confirmation notice the parties have reached agreement with
      the approval of the Director as to an alternative, be established in
      accordance with the terms of the Director's confirmation notice.

5.    With regard to the provisions of paragraphs 1 to 4, and following
      consultation with the Relevant Parties and with such other persons or
      bodies as appear to the Director to represent the interests of those
      likely to be affected, the Director may issue a direction that specified
      parts of the Relevant Conditions shall take effect at such time and in
      such cases or circumstances as he shall direct.

6.    In issuing a direction in accordance with paragraph 5 the Director shall
      have regard to the need to provide for effective arrangements to
      facilitate competition in the supply of electricity to customers and for
      the effective maintenance of existing trading arrangements in respect of
      the supply of electricity.

7.    This Condition shall cease to be in force on whichever is the latest of
      the following dates:

      (a)   30 September 1998;

      (b)   the date which is 6 months after the latest date upon which any
            provision in accordance with paragraph 3 (but excluding
            sub-paragraph 3(c)) ceases to have effect; or

      (c)   such other date as may be agreed between the Director and the
            Licensee.

8.    In this Condition:

Condition 5. Generation security standard

1.    The Licensee shall make arrangements sufficient to meet the generation
      security standard.

2.    Not later than 3 months before the end of each financial year, commencing
      with the financial year ending on 31 March 1991, the Licensee shall
      provide to the Director a statement complying with the provisions of
      paragraph 3.

3.    The statement to be provided to the Director under paragraph 2 shall:

      (a)   be signed by 2 directors of the Licensee;

      (b)   describe the arrangements made or to be made by the Licensee to meet
            the generation security standard in each of the 7 succeeding
            financial years;

      (c)   state the planning margin or margins adopted by the Licensee for the

            arrangements for trading energy and capacity with other persons,
            arrangements with qualifying customers and relevant purchasers,

            availability of generation, and load management (if any) of
            qualifying customers and relevant purchasers); and

      (e)   include such other matters as the Director shall specify in
            directions issued by the Director to the Licensee for the purpose of
            this Condition not later than 6 months before the end of the
            financial year in which the statement is provided.

4.    The Licensee shall upon request by the Director provide to the Director
      such information as the Director may require for the purpose of monitoring
      compliance with this Condition and to enable the Director (having regard
      to his statutory duties) to review the operation of the generation
      security standard.

5.    The Licensee shall not make or agree any alteration, other than an
      alteration to which paragraph 7 applies, to the arrangements described in
      any statement provided to the Director under paragraph 2 as having been
      made by the Licensee to meet the generation security standard for the
      first financial year covered by such statement.

6.    The Licensee shall:

      (a)   procure that, except to the extent that the Director shall otherwise
            approve, arrangements described in any statement provided to the
            Director under paragraph 2 as falling to be made by the Licensee to
            meet the generation security standard for the first financial year
            covered by such statement shall be made; and

      (b)   not make or agree any alteration, other than an alteration to which
            paragraph 7 applies to the arrangements so made.

7.    This paragraph applies to an alteration which the Director considers is
      unlikely to result in the Licensee failing to meet the generation security
      standard.

8.    Save as required by law, the Licensee shall not enter into any contract
      for the supply of electricity if the entering into of the contract would
      cause demand in the first year covered by the statement most recently
      provided to the Director under paragraph 2 to exceed the maximum demand
      which the Licensee can meet in that year without failing to meet the
      generation security standard as referred to in such statement, unless the
      Director shall consider that the entering into of the contract is unlikely
      to result in the Licensee failing to meet the generation security
      standard.

9.    Subject to paragraph 10, the Licensee shall not:

      (a)   enter into any contract to supply electricity to a person other than
            a qualifying customer if the Licensee has interrupted or reduced the
            supply of electricity to any qualifying customer (other than by
            reason of relevant constraints) and the interruption or reduction
            continues during the period or any part of the period in which
            electricity would otherwise be supplied under such contract; or

      (b)   interrupt or reduce the supply of electricity to any qualifying
            customer (except to the extent that such interruption or reduction
            is made by reason of relevant constraints) if at or shortly before
            the time of the interruption or reduction the Licensee enters into
            any contract to supply electricity to a person other than a
            qualifying customer during the period or part of the period that the
            supply is interrupted or reduced; or

      (c)   interrupt or reduce the supply of electricity to any qualifying
            customer in circumstances where:

            (i)   electricity is available for purchase under the terms of the
                  Pooling and Settlement Agreement or the trading system
                  established by the Trading Code at a price less than Value of
                  Lost Load; and

            (ii)  the Licensee is not prevented from purchasing such electricity
                  by reason of relevant constraints.

10.   Notwithstanding paragraph 9, the Licensee may interrupt or reduce a supply
      of electricity in circumstances where it is necessary to do so by reason
      of planned maintenance undertaken on the Licensee's Distribution System or
      Transmission System or by reason of a fault on or affecting either the
      Licensee's Distribution System or Transmission System or the quantities of
      electricity delivered into that system.

11.   In the event that the Director, after consultation with the Licensee,
      shall at any time or from time to time issue a direction to the Licensee
      for the purpose of this Condition to the effect that, in the opinion of
      the Director, it is desirable that the Licensee make arrangements such as
      are specified in the direction to meet the generation security

      standard, then the duty imposed by paragraph 1 shall not be capable of
      being discharged by the Licensee after such date as shall be specified for
      the purpose in the direction except by the Licensee making the
      arrangements so specified.

12.   The Director, after consultation with the Licensee, may at any time and
      from time to time by directions issued to the Licensee for the purpose of
      this Condition make such modifications to this Condition or any other
      Condition to which the Public Electricity Supply Licence is subject as, in
      the opinion of the Director, are the most appropriate to ensure that the
      Licensee's supply charges are restricted in circumstances where the
      Licensee fails to meet demand from its qualifying customers by reason of
      an insufficiency of electricity generation available for the purposes of
      supply by the Licensee to such customers.

13.   The duty of the Licensee under paragraph 1 may, in relation to qualifying
      customers whose premises are located in isolated areas, be discharged by
      the making of arrangements sufficient to meet a standard of generation
      security (other than the generation security standard) agreed between the
      Licensee and the Director.

14.   The provisions of this Condition are without prejudice to the duties of
      the Licensee under the Electricity Supply Regulations 1988.

15.   In this Condition:

      "generation security standard"      means:

                                          (a)   such standard of generation
                                                security as will ensure:

                                                      electricity to qualifying
                                                      customers will not be
                                                      discontinued in more than
                                                      9 years in any period of

                                                      reduced below usual

                                                for the purposes of supply by

                                                times of annual system peak
                                                demand to ensure that the
                                                standard of generation security
                                                at each such time will be not
                                                less than that referred to in

Condition 6. Obligation on economic purchasing

1.    Subject to paragraph 2, the Licensee shall:

      (a)   itself purchase;

      (b)   procure any affiliate of the Licensee to purchase; and

      (c)   insofar as it is able through the exercise of voting rights or
            otherwise to do so, procure any related undertaking of the Licensee
            to purchase

      electricity at the best effective price reasonably obtainable having
      regard to the sources available.

2.    In the discharge of its obligations under paragraph 1, the Licensee may
      additionally have regard to any considerations liable to affect its
      ability and that of any affiliate or related undertaking of the Licensee
      to discharge its obligations under this Condition in the future, including
      the future security, reliability and diversity of sources of fuel for own
      generation and of electricity available for purchase.

3.    In addition, and without prejudice to, the Licensee's obligations under
      paragraph 1:

      (a)   the Licensee shall purchase electricity under the terms of the
            Pooling and Settlement Agreement during any period that the Licensee
            is a pool member under the Pooling and Settlement Agreement (and, in
            its capacity as a member of the trading system established by the
            Trading Code, the Licensee shall make offers to purchase electricity
            and offers to acquire options to purchase electricity, and accept
            offers to sell electricity and offers to grant options to purchase
            electricity under such trading system) in the manner which is best
            designed to secure that the short term electricity requirements of
            the Licensee are met at the best effective price reasonably
            obtainable having regard to the sources available; and


Scottish Power                          117                          August 1998

      (b)   the Licensee shall procure that any affiliate of the Licensee which
            is a pool member under the Pooling and Settlement Agreement or a
            member of such trading system and (insofar as it is able through the
            exercise of voting rights or otherwise to do so) procure that any
            related undertaking of the Licensee which is a pool member under the
            Pooling and Settlement Agreement or a member of such trading system
            shall purchase electricity (or, in the case of such trading system,
            make and accept offers such as are referred to in sub-paragraph (a)
            above) in the manner which is best designed to secure that the short
            term electricity requirements of the affiliate or related
            undertaking are met at the best effective price reasonably
            obtainable having regard to the sources available.

4.    In determining the effective price at which electricity is purchased by
      the Licensee or any affiliate or related undertaking of the Licensee,
      regard shall be had to any payments made or received or to be made or
      received for the grant of or pursuant to any electricity purchase
      contract.

5.    Paragraphs 1 to 4 shall apply mutatis mutandis where the Licensee (or any
      affiliate or related undertaking of the Licensee) exercises a discretion
      or (by agreement or otherwise) varies the terms of an existing agreement
      (whether or not entered into prior to the date on which the Public
      Electricity Supply Licence comes into force) in such a manner as to alter
      the effective price under such agreement.

6.    The Licensee shall not be in breach of this Condition by reason only of
      performing a must-take obligation to purchase electricity under a relevant
      electricity agreement or acquiring electricity from own generation in
      circumstances where the Licensee has a must-take obligation to purchase
      the fossil fuel which is used to generate the electricity in question
      under a relevant fuel agreement.

7.    For the purpose of this Condition, an agreement which imposes an
      obligation on the Licensee to make a payment to another party to the
      agreement in the event that the Licensee does not purchase electricity (or
      a minimum quantity of electricity) under the agreement shall be deemed to
      be an agreement under which the Licensee has a must-take obligation to
      purchase electricity and any quantity of electricity purchased by the

      Licensee pursuant to the agreement shall be deemed to have been purchased
      in performance of a must-take obligation to purchase electricity if the
      Licensee would have been obliged to make a payment to another party to the
      agreement had it not purchased such quantity of electricity.

8.    For the purpose of this Condition:

Condition 7C. Provisions relating to the connection of metering equipment

1.    On application made by any person the Licensee shall, subject to paragraph
      5, offer to enter into an agreement authorising that person to connect
      metering equipment to the Licensee's Distribution System.

2.    In making an offer to enter into an agreement specified in paragraph 1,
      the Licensee shall set out:

      (a)   the date from which the applicant is authorised to undertake
            connections;

      (b)   the procedures to be adopted by the applicant when making
            connections, with particular regard to those relating to safety; and

      (c)   such other detailed terms as are or may be appropriate for the
            purposes of the agreement.

3.    The Licensee shall offer terms for agreements in accordance with paragraph
      1 as soon as practicable and (save where the Director consents to a longer
      period) in any event not more than 28 days after receipt by the Licensee
      from any person of an application containing all such information as the
      Licensee may reasonably require for the purpose of formulating the terms
      of the offer.

4.    In the offering of the terms in accordance with paragraph 1, the Licensee
      shall not show undue preference to or exercise undue discrimination
      against any person or class of persons.

5.    The Licensee shall not be obliged pursuant to this Condition to offer to
      enter or to enter into any agreement:

      (a)   (in respect of non-half-hourly metering equipment) which comes into

      (b)   where to do so would be likely to cause the Licensee to be in breach
            of those provisions referred to at sub-paragraph 7(a) of Condition
            2B of Part VI.

6.    If, after a period which appears to the Director to be reasonable for the
      purpose, the Licensee has failed to enter into an agreement with any
      person entitled or claiming to be entitled thereto pursuant to a request
      under this Condition, the Director may, on the application of such person
      or the Licensee, settle any terms of the agreement in dispute between the
      Licensee and that person in such manner as appears to the Director to be
      reasonable.

7.    In so far as any person entitled or claiming to be entitled to an offer
      under this Condition wishes to proceed on the basis of the agreement as
      settled by the Director, the Licensee shall forthwith enter into and
      implement such agreement in accordance with its terms.

8.    If the Licensee or other party to such agreement proposes to vary the
      terms of any agreement entered into pursuant to this Condition in any
      manner provided for under such agreement, the Director may, at the request
      of the Licensee or other party to such agreement, settle any dispute
      relating to such variation in such manner as appears to the Director to be
      reasonable.

1.    The Licensee shall not, in the course if its Supply Business, enter into
      an agreement with any person for the provision of an electricity meter at

      is likely to restrict, distort or prevent competition in the supply of
      electricity.

            and (without prejudice to the foregoing) making express provision as
            to the matters referred to in paragraph 5; and

      (b)   which is designed so as:

            (i)   to permit the development, maintenance and operation of an
                  efficient, co-ordinated and economical system for the

            reasonably thinks fit for the achievement of the objectives referred
            to in sub-paragraph (b) of paragraph 1; and

      (c)   any written representations or objections from Authorised
            Electricity Operators (including any proposals by such operators for

            the course of the review) arising during the consultation process
            and subsequently maintained.

3.    Revisions to the Distribution Code proposed by the Licensee and sent to
      the Director pursuant to paragraph 2 shall require to be approved by the

      sub-paragraph (c) of paragraph 2, and following such further consultation
      (if any) as the Director may consider appropriate, the Director may issue
      directions requiring the Licensee to revise the Distribution Code in such
      manner as may be specified in the directions, and the Licensee shall
      forthwith comply with any such directions.

5.    The Distribution Code shall include:

      (a)   a distribution planning and connection code containing:

            (i)   connection conditions specifying the technical, design and

      would become liable for the provision of such services and of the other
      terms, likely to have a material impact on the conduct of his business,
      upon which the service would be provided and (without prejudice to the

Condition 8F. Functions of the Director

1.    If, after a period which appears to the Director to be reasonable for the
      purpose, the Licensee has failed to enter into an agreement with any
      person entitled or claiming to be entitled thereto pursuant to a request
      under Condition 8C, the Director may, on the application of such person or
      the Licensee, settle any terms of the agreement in dispute between the
      Licensee and that person in such manner as appears to the Director to be
      reasonable having (in so far as relevant) regard in particular to the
      following considerations:

      (a)   that such person should pay in respect of the services required the
            whole or the appropriate proportion of such sum as is determined in
            accordance with paragraph 4 of Condition 8E;

      (b)   that the performance by the Licensee of its obligations under the
            agreement should not cause it to be in breach of those provisions
            referred to at subparagraph 7(a) of Condition 2B of Part VI; and

      (c)   that the terms and conditions of the agreement so settled by the
            Director and of any other agreements entered into pursuant to a
            request under Condition 8C should be, so far as circumstances allow,
            in as similar a form as is practicable.

2.    In so far as any person entitled or claiming to be entitled to an offer
      under Condition 8C wishes to proceed on the basis of the agreement as
      settled by the Director, the Licensee shall forthwith enter into and
      implement such agreement in accordance with its terms.

3.    If any party to such agreement proposes to vary the contractual terms of
      any agreement for any Metering and Data Services entered into pursuant to
      Condition 8C or this Condition in any manner provided for under such
      agreement, the Director may, at the request of that party, settle any
      dispute relating to such variation in such manner as appears to the
      Director to be reasonable.

      such information shall be treated as confidential information for the
      purposes of this Condition and, subject to paragraph 7, the provisions of

      meter or apparatus installed by the Licensee in the like position and for
      a like purpose in relation to the customer, does not exceed 10 watts
      except where otherwise agreed with the customer.

Condition 12. Code of practice on payment of bills and guidance for dealing with
customers in difficulty

1.    The Licensee shall, no later than 1 January 1998, prepare and submit to
      the Director for his approval a code of practice concerning the payment of
      electricity bills by its Domestic Customers, including appropriate
      guidance for the assistance of such customers who, through misfortune or
      inability to cope with electricity supplied on credit terms, may have
      difficulty in paying such bills.

2.    The code of practice shall include procedures by which the Licensee can
      distinguish customers in difficulty (the "relevant customers") from others
      in default and can:

      (a)   provide general information as to how relevant customers might
            reduce their bills in the future by the more efficient use of
            electricity;

      (b)   where such a facility is available, accept in payment for

            security benefits payable to relevant customers;

      (c)   detect failures by relevant customers to comply with arrangements
            entered into for paying by instalments charges for electricity
            supplied;

      (d)   make such arrangements so as to take into account the customers'
            ability to comply with them;

      (e)   ascertain with the assistance of other persons or organisations, the
            ability of customers to comply with such arrangements;

      (g)   arrange for the calibration of any prepayment meter so provided so
            as to take into account the customers' ability to pay any of the
            charges due from them under such arrangements in addition to the
            other charges lawfully being recovered through the prepayment meter.

3.    In formulating the procedures referred to at paragraph 2 the Licensee
      shall have particular regard:

      (a)   to the purpose of avoiding, in so far as is practicable, the
            disconnection of premises occupied by relevant customers otherwise
            than following compliance by the Licensee with such procedures; and

      (b)   to the interests of relevant customers who are of pensionable age or
            disabled or chronically sick and to the purpose of avoiding, in so
            far as is practicable, the disconnection of premises occupied by
            such customers during the winter months of each year,

      and the procedures shall be designed for the achievement of such purposes.

4.    This Condition is subject to the provisions of Condition 17A.

      Committee a report dealing with the matters mentioned in paragraphs 1 and

      consent, individual Designated Customers referred to therein cannot
      readily be identified.

5.    The report shall be presented, so far as is reasonably practicable, in a
      standard form designated by the Director for the purposes of this
      Condition.

10.   In this Condition:

      "relevant second tier supply     means arrangements which the Director

            be known as the Settlement Agreement for Scotland, which shall
            contain terms on which the settlement system will be made available
            and shall comply with the other requirements of this Condition; and

      (d)   to offer (or procure that a third party offers) to make available
            the settlement system, pursuant to and in accordance with the

            system in accordance with the objects set out at paragraph 2.

2.    The objects set out at this paragraph are:

      (a)   to enable private electricity suppliers to have their volumetric
            purchases of electricity from Portfolio Generators and from parties
            to the Pooling and Settlement Agreement correctly allocated to them;

      (b)   to enable private electricity suppliers and Portfolio Generators,
            other than the Licensee and the other Scottish Public Electricity
            Supplier, to have their

3.    The Settlement Agreement for Scotland shall provide - to the extent
      required to facilitate the proper functioning of arrangements established
      in accordance with Condition 23, or as otherwise agreed by the Licensee
      and the other Scottish Public Electricity Supplier - for the fulfilment of

            estimate of the reasonable costs of efficiently establishing,
            operating and maintaining such a system;

      (b)   which provide for the variation of the Settlement Agreement for
            Scotland following consultation with the parties, or representatives

Condition 25. Designated Premises

1.    For the purposes of this Licence, the question whether any premises are
      "Designated Premises" shall be determined in accordance with the
      provisions of this Condition.

2.    Premises are Designated Premises if they are either:

      (a)   Domestic Premises; or

      (b)   premises at which, in the reasonable expectation of the Licensee at
            the time of entering into a contract for the supply of electricity
            to such premises, the normal annual consumption of electricity will
            amount to no more than 12,000 kWh,

      but excluding premises referred to at sub-paragraph (b) which receive an
      unmetered supply, or which are supplied through half-hourly or maximum
      demand metering equipment or under the terms of a multi-site contract.

3.    For the purposes of this Condition, a "multi-site contract" is a contract
      for the supply of electricity both to any premises which do not fall
      within the terms of sub-paragraphs 2(a) or (b) and to one or more other
      premises (not being Domestic Premises), all of which premises are owned or
      occupied by:

      (a)   the same person or body of persons whether corporate or
            unincorporate; or

      (b)   an undertaking (the "principal undertaking") and any holding
            company, subsidiary, or subsidiary of the holding company of that
            principal undertaking, or any other undertaking in which the
            principal undertaking has a participating interest.

4.    Any premises supplied by the Licensee which (in accordance with paragraphs
      1 to 3) were not Designated Premises at the time at which the Licensee
      entered into a contract for their supply shall, notwithstanding subsequent
      changes to the nature or level of the

      consumption of electricity at those premises, not become Designated
      Premises for the purposes of this Licence prior to the time at which they
      cease to be supplied by the Licensee.

5.    Any premises supplied by the Licensee which (in accordance with paragraphs
      1 to 3) were Designated Premises at the time at which the Licensee entered
      into a contract for their supply shall cease to be Designated Premises for
      the purposes of this Licence where:

      (a)   they have been continuously supplied by the Licensee for a period of
            at least 12 months and:

            (i)   they are not, or are no longer, Domestic Premises; and

            (ii)  it is reasonably to be expected that the normal annual
                  consumption of electricity at the premises will amount to more
                  than 12,000 kWh; or

      (b)   (not being, or being no longer, Domestic Premises) the premises
            commence receipt of an unmetered supply or a supply through
            half-hourly or maximum demand metering equipment or under the terms
            of a multi-site contract.

6.    In this Condition:

      "maximum demand metering            means metering equipment which is
      equipment"                          capable of recording the demand for
                                          electricity supplied to premises
                                          during the half hour of maximum demand
                                          in any period of supply.

Condition 26. Terms for supply of electricity incompatible with Licence
Conditions

1.    Without prejudice to its rights and obligations under the Act, the
      Licensee shall not enter into, offer to enter into or enter into a
      variation of any contract for the supply of electricity to a customer at
      Designated Premises otherwise than on terms which comply with the
      Licensee's obligations under this Licence.

2.    The Licensee shall not enforce or take advantage of any term of a contract
      for the supply of electricity to a customer at Designated Premises if the
      inclusion of that term was in breach of the provisions of this Licence.

3.    The Licensee shall not take advantage of the omission of any term from a
      contract for the supply of electricity to a customer at Designated
      Premises if the omission of that term was in breach of the provisions of
      this Licence.

Condition 27. Limitation on requirements for termination fees

1.    Where the Licensee enters into any Designated Supply Contract in the
      circumstances set out at paragraph 2 it may not in such contract provide
      for the payment of any termination fee by the Designated Customer.

2.    Paragraph 1 applies in respect of any Designated Supply Contract entered
      into prior to the date which is 90 days following the earliest date
      specified (and not subsequently withdrawn or varied to a later date) in
      any direction or variation of a direction issued by the Director, pursuant
      to condition 3 of the licence held by any Second Tier Supplier, in
      relation to the supply of electricity to all premises within the
      authorised area.

Condition 28. Revision of the Contract Terms Conditions

1.    The Director, in accordance with the provisions of this Condition, may
      from time to time review (in whole or in part) the provisions and
      operation of the Contract Terms Conditions in the licences of all
      Electricity Suppliers with a view to establishing whether any revision
      should be made to the Contract Terms Conditions in all such licences.

2.    At the commencement of any review by the Director, the Director shall:

      (a)   give to all Relevant Parties a notice in writing which sets out the
            terms of the review and of any proposals in connection therewith and
            which invites the submission of any representations by a specified
            date (being not less than 28 days after the date of the notice); and

      (b)   publish such notice or an accurate summary of it in a manner which
            will, in the opinion of the Director, secure adequate publicity for
            it.

3.    On receiving from the Director notice of such a review the Licensee may
      submit any representations on matters within the terms of the review by
      the date specified in the notice.

4.    As soon as practicable following the completion of any such review, the
      Director shall send to each Relevant Party, and to any person who has made
      representations to him by virtue of the notice published under
      sub-paragraph 2(b), a copy of:

      (a)   a report on the outcome of such review;

      (b)   any revisions which he proposes to make, having regard to any
            representations received during such review, to the Contract Terms
            Conditions in the licences of all Electricity Suppliers;


Scottish Power                        189                            August 1998
<PAGE>

      (c)   a statement of his reasons for proposing those revisions; and

      (d)   a notice specifying the time (being not less than 28 days from the
            date the Director issues the notice) within which Electricity
            Suppliers which are entitled to supply electricity to Designated
            Premises shall state whether or not they consent to the proposed
            revisions to the Contract Terms Conditions in their licences.

5.    A revision proposed to be made by the Director to the Contract Terms
      Conditions of all Electricity Suppliers may be made only where the
      Director is satisfied that the figures determined in accordance with
      paragraphs 6 and 7 (expressed as a percentage) are each not less than 90
      per cent.

6.    The figure determined in accordance with this paragraph shall be
      calculated under the following formula:

                              C   x  100
                            ----
                            C+N

      where:

            C =   the number of Designated Premises supplied on contract by
                  consenting Electricity Suppliers; and

            N =   the number of Designated Premises supplied on contract by
                  non-consenting Electricity Suppliers

      as estimated (in each case) by the Director on the basis of the
      information most recently available to him.

7.    The figure determined in accordance with this paragraph shall be
      calculated under the following formula:


Scottish Power                        190                            August 1998

                            ----
                            C+N

      where:

            C =   the number of consenting Electricity Suppliers; and

            N =   the number of non-consenting Electricity Suppliers.

8.    In paragraphs 6 and 7 the expressions "consenting" and "non-consenting"
      refer (as the case may be) to the consent or otherwise of Electricity
      Suppliers which are entitled to supply electricity to Designated Premises
      to the proposed revision to the Contract Terms Conditions in their
      licences.

9.    Where the Director is satisfied that the figures determined in accordance
      with paragraphs 6 and 7 (expressed as a percentage) are each not less than
      90 per cent the Director may amend the Contract Terms Conditions of the
      Licensee in accordance with the proposed revision.

10.   No revision made to the Contract Terms Conditions by virtue of this
      Condition may introduce an obligation in respect of any matter other than
      one which:

      (a)   is provided for, or is reasonably ancillary to a matter provided
            for, under the Contract Terms Conditions on the date on which such
            Conditions come into force;

      (b)   concerns the terms of contracts offered or entered into by the
            Licensee for the supply of electricity to Designated Premises; or

      (c)   concerns any dealings with customers by or on behalf of the Licensee
            prior to and for the purpose of offering or entering into contracts
            for the supply of electricity to Designated Premises.

      (a)   be in a standard form, save that there may (subject to paragraph 4)
            be different forms for different areas, cases and circumstances;

      (b)   set out all the terms and conditions, including terms as to price,
            on which the Licensee will supply electricity in the relevant case;
            and

      (c)   contain terms reflecting the termination provisions of Conditions 33
            and 34.

4.    Where the Secretary of State has specified an area of Scotland by an order
      made pursuant to section 3(2)(a) of the Act, a Designated Supply Contract
      for the supply of electricity to premises within that area shall be on
      terms as to price which are the same as those for an equivalent supply to
      any other premises within that area.

5.    Any Designated Supply Contract for both the supply of electricity and the
      provision of goods or services shall identify separately the charge for
      that supply from the charge for the goods or services.

6.    Where a Designated Supply Contract may be terminated by a customer by
      virtue of any provision included in that contract in compliance with
      Conditions 33 and 34, the

      Licensee may at its discretion accept a lesser period of notice than is
      specified in that provision.

7.    Nothing in this Licence shall prevent the Licensee from entering into a
      Designated Supply Contact which contains provisions for its termination
      that are additional to and do not derogate from those set out at
      Conditions 33 and 34.

Condition 30. Contractual terms

1.    Where the Licensee offers to supply electricity to Domestic Premises under
      Designated Supply Contracts, it shall have available forms of Designated
      Supply Contract which provide for the payment of charges for electricity
      supplied to Domestic Premises:

      (a)   by prepayment through a prepayment meter;

      (b)   by different methods, including:

            (i)   by cash, at such places and to such persons as are reasonable
                  in all the circumstances; and

            (ii)  by cheque, and

      (c)   at a reasonable range of different intervals, including:

            (i)   paying monthly a predetermined sum; and

            (ii)  paying quarterly in arrears.

2.    Before entering into any contract to supply electricity to Domestic
      Premises (other than through a prepayment meter) the Licensee shall inform
      the customer of and offer to enter into Designated Supply Contracts which
      comply with sub-paragraphs 1(b) and (c).

3.    The Licensee shall process all requests for a supply of electricity to
      Designated Premises without undue preference or undue discrimination.

4.    The Licensee shall send copies of each of the forms of Designated Supply
      Contract (as revised from time to time) under which it supplies or offers
      to supply electricity:

      (a)   on receipt of a request, to any person; and

      (b)   not later than the date on which it first offers to supply
            electricity under each such form of Designated Supply Contract (or
            revision thereof), to the Director.

5.    The Licensee shall prepare, in respect of each form of Designated Supply
      Contract:

      (a)   a document which sets out an accurate summary of the Principal Terms
            of that form of Designated Supply Contract; and

      (b)   particulars of inducements offered to any person entering into such
            a contract which might reasonably be expected materially to
            influence the decision whether or not to enter into it.

6.    The Licensee shall publish the documents and particulars referred to at
      paragraph 5 in a manner that will in the opinion of the Licensee secure
      adequate publicity for them, and shall send copies of them to the Director
      no later than the date on which they are published.

Condition 31. Notification of terms

1.    Before entering into any Designated Supply Contract the Licensee shall
      take all reasonable steps to draw the attention of the customer to the
      Principal Terms of the contract.

2.    Where the Licensee has entered into a Designated Supply Contract it shall
      (except where it has already done so) provide the customer within 2
      working days of the date of the contract with a copy of its full terms and
      conditions.

3.    Subject to paragraph 4 the Licensee shall, at least 30 days before any
      Designated Supply Contract to supply electricity for a specified period is
      due to expire, send to the customer:

      (a)   a written offer to enter into a new contract for supply from the
            date of expiry of the existing contract, drawing the attention of
            the customer to the Principal Terms relevant to that offer;

      (b)   an accurate summary of the Principal Terms of other contracts which
            the Licensee will make available to the customer; and

      (c)   details of how the customer can obtain continuity of supply from the
            Licensee.

4.    Paragraph 3 shall not apply where:

      (a)   the customer has informed the Licensee that he does not wish to
            continue to be supplied by it after the expiry of the existing
            contract; or

      (b)   it is not reasonable in all the circumstances for the Licensee to be
            required to continue to supply that customer and the Licensee has
            (at least 30 days before the contract was due to expire) both
            notified the customer to that effect and informed him that he must
            make arrangements to obtain a supply from another Electricity
            Supplier.

5.    Where a Designated Supply Contract allows for its unilateral variation (in
      any respect) by the Licensee and is so varied to the significant
      disadvantage of the customer, the Licensee shall within 10 days of the
      variation give to the customer written notice:

      (a)   of the variation;

      (b)   of the customer's right to terminate the contract; and

      (c)   of the effect of paragraph 6.

6.    Where a customer gives to the Licensee a valid notice of termination
      within 14 days of receiving notice under paragraph 5, the Licensee shall
      treat the variation as ineffective and shall neither enforce nor take
      advantage of it.

7.    Where the Licensee believes that any of its customers no longer occupies
      or is about to vacate Designated Premises to which it supplies
      electricity, it shall as soon as reasonably practicable provide any new
      occupier of those premises with an accurate summary of the Principal Terms
      of contracts it will make available to him.

Condition 32. Security deposits

1.    The Licensee shall not, in respect of the supply of electricity under any
      Designated Supply Contract, require a deposit:

      (a)   where the customer is prepared to be supplied through a prepayment
            meter and it is reasonably practicable in all the circumstances
            (including in particular the risk of loss or damage) for the
            Licensee to provide such a meter; or

      (b)   where it is otherwise unreasonable in all the circumstances to do
            so.

2.    Any deposit required of a Designated Customer may be 1 1/2 times the value
      of the average quarterly consumption of electricity reasonably expected at
      the relevant premises, or more if that is reasonable in all the
      circumstances.

3.    Where the Licensee requires a deposit of a Designated Customer it shall at
      the same time inform that customer of the effect of paragraphs 5 and 7.

4.    Where the Licensee holds any deposit it shall pay interest, at a rate it
      shall fix from time to time with the approval of the Director, on every
      sum of 50p deposited for every 3 months during which that sum is held.

5.    Subject to paragraph 6, any deposit given by a Designated Customer shall
      be repaid (with interest) by the Licensee:

      (a)   within 14 days where, in the previous 12 months, the customer has
            paid all charges for electricity supplied within 28 days of each
            written demand made; or

      (b)   as soon as reasonably practicable, and in any event within 1 month,
            where the Licensee has ceased to supply the customer and the
            customer has paid all charges for electricity supplied.

6.    Sub-paragraph 5(a) shall not apply where it is reasonable in all the
      circumstances for the Licensee to retain the deposit.

7.    Any dispute arising under this Condition between the Licensee and a
      Designated Customer may be referred by either party to the Director. The
      Director shall determine any such dispute, following such practice and
      procedure as he considers appropriate.

Condition 33. Termination of contracts on notice

1.    Each Designated Supply Contract shall contain a term allowing the customer
      to terminate such contract at any time by:

      (a)   giving to the Licensee a valid notice of termination; and

      (b)   subject to paragraph 6, paying to the Licensee on demand a
            termination fee.

2.    A notice of termination is valid where it is given at least 28 days in
      advance of the date on which it is to take effect and where, not later
      than that date, the requirements of paragraphs 3 and (unless the Licensee
      expressly agrees to waive it) 4 are satisfied.

3.    The requirement of this paragraph is that either:

      (a)   another Electricity Supplier commences a supply of electricity to
            the relevant premises; or

      (b)   the relevant premises are cut off because the customer at those
            premises has ceased to require a supply.

4.    The requirement of this paragraph is that no charges for electricity
      supplied to the customer (whether at the relevant premises or at any
      premises previously occupied by him), having been demanded in writing
      prior to the notice of termination being given, remain owing to the
      Licensee more than 28 days after that demand was made.

5.    Each Designated Supply Contract shall provide that a notice of termination
      which is not valid shall not be effective to terminate such contract.

6.    A termination fee shall not be demanded of a customer where:

      (a)   the contract was terminated under any provision of Condition 34;


Scottish Power                         201                           August 1998
<PAGE>

      (b)   the contract was a contract of indefinite length, and was terminated
            other than during a fixed term period;

      (c)   the Licensee notified the customer, under paragraph 5 of Condition
            31, of a unilateral variation of the contract and the customer gave
            notice of termination in accordance with paragraph 6 of that
            Condition; or

      (d)   the contract was a contact to which paragraph 4 of Condition 34
            applied and the Licensee did not, before entering into it, take all
            reasonable steps to draw the attention of the customer to the effect
            of the term set out at that paragraph.

7.    Where a termination fee is payable, it shall be of an amount not greater
      than that which the Licensee may in all the circumstances reasonably
      require.

Condition 34. Termination of contracts in specified circumstances

1.    Each Designated Supply Contract shall provide that the contract will
      terminate:

      (a)   on the date on which the customer ceases to own or occupy the
            relevant premises, having given the Licensee at least 2 working
            days' notice of that date; or

      (b)   where the customer has ceased to own or occupy the premises without
            giving the Licensee at least 2 working days' notice, on the first in
            time of:

            (i)   the second working day after he has given notice to the
                  Licensee;

            (ii)  the next day on which the meter is due to be read; and

            (iii) the date on which any subsequent owner or occupier enters into
                  a contract or tariff agreement for the supply of electricity
                  to the premises.

2.    Each Designated Supply Contract shall provide that where it is terminated
      by virtue of a term included in the contract in compliance with paragraph
      1, the customer shall remain liable for any charges for the supply of
      electricity until the date of termination.

3.    Each Designated Supply Contract shall provide that it may be terminated
      immediately by either party at any time after the Director or the
      Secretary of State has revoked this Licence.

4.    Any Designated Supply Contract which:

      (a)   provides for the Licensee to supply electricity for a specified
            period of more than 12 months; or

      (b)   contains an initial fixed term period,

<PAGE>

      shall provide that it may be terminated immediately by the customer at any
      time within 5 working days of the date of the contract.

5.    Where a Designated Supply Contract is for both the supply of electricity
      and the provision of goods or services:

      (a)   any reference in the Contract Terms Conditions to its termination is
            a reference to its termination in respect of the supply of
            electricity alone; and

      (b)   on its termination by virtue of any provision of the Contract Terms
            Conditions, the Licensee may require the customer to give any
            reasonable security for his future compliance with the contract for
            the provision of goods or services.

Condition 35. Assignment of outstanding charges

1.    This Condition shall apply where:

      (a)   the Licensee has commenced the supply of electricity to Domestic
            Premises at which a supply was previously given to its customer by
            the Previous Supplier;

      (b)   the customer has failed to pay, within 28 days of receiving a demand
            in writing, any charges due from him to the Previous Supplier for
            the supply of electricity at those premises;

      (c)   that failure occurred after either the Previous Supplier was
            informed of the change of supplier or the Licensee commenced supply
            to the premises (whichever is the earlier);

      (d)   the Previous Supplier has given written notice to the customer that
            it proposes to assign the debt to the Licensee, which may be
            entitled to reclaim from him its costs in recovering the debt; and

      (e)   the Licensee has received from the Previous Supplier a notice in
            accordance with paragraph 2.

2.    A notice in accordance with this paragraph is one which:

      (a)   is given at least 14 days after the notice referred to at
            sub-paragraph 1(d) and is received by the Licensee within 90 days of
            it commencing a supply to the premises;

      (b)   specifies the amount of the debt which remains unpaid;

      (c)   states that the Previous Supplier has used all reasonable endeavours
            to recover the debt, which remains unpaid at least 42 days after
            being demanded in writing; and


Scottish Power                         205                           August 1998
<PAGE>

      (d)   states that the Previous Supplier intends to assign to the Licensee
            the debt, up to a maximum sum of one-third of the value (calculated
            in accordance with the charges of the Previous Supplier to the
            customer immediately before it ceased to supply him) of the average
            annual consumption reasonably expected of the customer.

3.    Where this Condition applies the Licensee shall, within 60 days of
      receiving a notice under paragraph 2 and in consideration of the
      assignment of the debt, pay to the Previous Supplier the sum specified
      under sub-paragraph 2(d) (less, where they cannot be reclaimed from the
      customer, its reasonable costs of recovering that debt).

4.    For the purposes of this Condition, a customer shall not be regarded as
      being in debt to the Previous Supplier to the extent to which that debt is
      genuinely in dispute.

5.    In this Condition:

      "Previous Supplier"     means, in relation to any premises, the
                              Electricity Supplier which supplied electricity to
                              those premises immediately prior to the
                              commencement of supply by the Licensee.

Condition 36. Modification of Provisions under Conditions 33 and 35

1.    In this Condition, the "relevant provisions" are the provisions of
      paragraph 4 of Condition 33 and Condition 35 of Part V (or any of them).

2.    Where the Director considers (having regard to any representations made to
      him) that in any specified class of cases the relevant provisions do not
      fulfil the requirements of paragraph 4, he may direct that they shall
      cease to have effect in that class of cases.

3.    Where a direction under paragraph 2 has been made and the Director
      considers (having regard to any representations made to him) that in the
      specified class of cases the relevant provisions would fulfil the
      requirements of paragraph 4, he may direct that they shall again have
      effect in those cases.

4.    The requirements of this paragraph are that, in the specified class of
      cases, the operation of the relevant provisions:

      (a)   significantly reduces the number of unrecovered debts otherwise to
            be expected; or

      (b)   involves expenditure in debt recovery which is less than the
            reduction in the value of unrecovered debts which it achieves.

5.    Any direction under paragraphs 2 or 3 shall be made by a notice given to
      the Relevant Parties which shall specify:

      (a)   the relevant provisions to which it applies;

      (b)   the class of cases to which it applies; and

      (c)   the date on which it shall have effect (being, in a direction under
            paragraph 3, at least 3 months after the notice is given).

6.    In this Condition:

      "Relevant Parties"      means the Licensee, all other Electricity
                              Suppliers, the Electricity Consumers' Committees
                              and such other persons or bodies as in the opinion
                              of the Director are representative of those likely
                              to be affected by a revision to the relevant
                              provisions.

Condition 37. Marketing of electricity to Designated Customers

1.    This Condition applies to the marketing activities of the Licensee in
      respect of the supply or the proposed supply of electricity to the
      Designated Premises.

2.    This Condition shall cease to have effect on a date (the "termination
      date") which shall be 31 March 2000, provided that:

      (a)   if the Director, after consultation with the Licensee, all other
            Electricity Suppliers, the electricity consumers' committees and
            such other persons or bodies as in the opinion of the Director are
            representative of those likely to be affected, gives notice for the
            purposes of this Condition generally:

            (i)   by publishing the notice in such a manner as the Director
                  considers appropriate for the purpose of bringing it to the
                  attention of persons likely to be affected by it; and

            (ii)  by sending a copy of the notice to all Electricity Suppliers
                  and electricity consumers' committees,

            that he considers that the development of competition in electricity
            supply is such as to require the continuation of any part of this
            Condition until such date - not later than two years from the
            termination date - as may be specified in the notice (the "new
            termination date"), then such part of this Condition as may be
            specified in the notice shall continue to apply as if for the
            termination date there were substituted the new termination date;
            and

      (b)   notice under sub-paragraph (a) may be given on more than one
            occasion.

3.    The Licensee shall:

      (a)   set up appropriate procedures for the selection of staff employed or
            engaged in roles the principal duties of which involve oral
            communication with Designated Customers for the purposes of the
            marketing activities of the Licensee;

      (b)   take all reasonable steps to ensure that each such person is trained
            so as to have a sufficient understanding of:

            (i)   the arrangements for competition in electricity supply in
                  Scotland; and

            (ii)  the Principal Terms of Designated Supply Contracts made
                  available by the Licensee;

            such that any relevant advice given by him to Designated Customers
            is not misleading;

      (b)   the reasons for its proposal, together with a summary of responses
            received from such parties as were consulted by the Licensee.

5.    A proposal made by the Licensee in accordance with paragraph 4 shall

6.    The Licensee shall, in such manner as will in the opinion of the Licensee
      secure adequate publicity therefor:

      (a)   publish, no later than 31 December 1997, the Standard Terms of
            Connection approved by the Director in accordance with paragraph 1;

            the supply of electricity to premises which are to be supplied
            through an established connection without at the same time (in
            respect of such premises) entering into an agreement with the
            customer on the Standard Terms of Connection; or

      (b)   do anything to prevent the conclusion of an agreement on the

            Licensee in accordance with an agreement for use of system.

8.    The Licensee may at any time agree with any person (by way of variation to

Condition 2D. Functions of the Director

1.    If, after a period which appears to the Director to be reasonable for the
      purpose, the Licensee has failed to enter into an agreement with any
      person entitled or claiming to be entitled thereto pursuant to a request
      under Condition 2B or 2C, the Director may, on the application of that
      person or the Licensee, settle any terms of the agreement in dispute
      between the Licensee and that person in such manner as appears to the
      Director to be reasonable having (insofar as relevant) regard in
      particular to the following considerations:

      (a)   that such person should pay to the Licensee:

            (i)   in the case of the provision of top-up or standby supplies or
                  sales of electricity, such sum as is determined in accordance
                  with paragraph 3 of Condition 2;

            (ii)  in the case of exempt supply services, such sum as is
                  determined in accordance with paragraph 6 of Condition 2;

            (iii) in the case of provision of use of system, the use of system
                  charges determined in accordance with paragraph 8 of Condition
                  2; and

            (iv)  in the case of provision of a connection, or a modification to
                  an existing connection, to the system the whole or an
                  appropriate proportion (as determined in accordance with
                  paragraph 3 of Condition 2B) of the costs referred to in
                  sub-paragraph 10(a) of Condition 2, together with a reasonable
                  rate of return on the capital represented by such costs;

      (b)   that no such person should pay any charges such as are referred to
            in subparagraph 9(b) of Condition 2 in respect of any connection to
            the Licensee's Transmission System or any modification to an
            existing connection made prior to such date as shall be specified in
            a direction issued by the Director for the purposes of this
            Condition and that no such charges should be paid in respect of


Scottish Power                         237                           August 1998

            any such connection or modification made after such date unless the
            Director is satisfied that the extension or reinforcement in respect
            of which the charges are to be paid was rendered necessary or
            appropriate by virtue of providing connection to or use of system to
            the person or making such a modification;

      (c)   that the performance by the Licensee of its obligations under the
            agreement should not involve the Licensee in a breach such as is
            referred to in subparagraph 7(a) of Condition 2B;

      (d)   that any methods by which the Licensee's System is connected to any
            other system for the transmission or distribution of electricity
            accord (insofar as applicable to the Licensee) with the Grid Code
            and with the Distribution Code;

      (e)   that the terms and conditions of the agreement so settled by the
            Director and of any other agreements entered into by the Licensee
            pursuant to an application under Condition 2B or 2C should be, so
            far as circumstances allow, in as similar a form as is practicable;
            and

      (f)   in the case of exempt supply services, that the agreement for the
            provision of exempt supply services should make provision for all
            the matters set out at paragraph 5 of Condition 2B.

2.    In so far as any person entitled or claiming to be entitled to an offer
      under Condition 2B or 2C wishes to proceed on the basis of the agreement
      as settled by the Director, the Licensee shall forthwith enter into and
      implement such agreement in accordance with its terms.

3.    If either party to such agreement proposes to vary the contractual terms
      of any agreement for exempt supply services, for the provision of a
      connection or for the modification of an existing connection to the
      Licensee's System, for the retention of an established connection to such
      system or for use of system entered into pursuant to Condition 2B or 2C or
      under this Condition in any manner provided for under such agreement, the

      Director may, at the request that party, settle any dispute relating to
      such variation in such manner as appears to the Director to be reasonable.

Condition 3. Basis of charges for use of the Scottish interconnection

1.    Unless (and except for so long as) the Director approves otherwise,
      charges for use of the Scottish interconnection shall be set at a level
      which will enable the Licensee to recover no more than a reasonable rate
      of return on the relevant proportion of the capital represented by the
      Scottish interconnection.

2.    The Licensee shall as soon as practicable after the Transmission Licence
      has come into force, and, in any event, not later than such date as the
      Director shall specify, prepare a statement approved by the Director
      setting out the basis upon which charges for use of the Scottish
      interconnection will be made, such statement to be in such form and to
      contain such detail as shall be necessary to enable any person to make a
      reasonable estimate of the charges to which it would become liable for use
      of the Scottish interconnection, and (without prejudice to the foregoing)
      including the information required to be included therein pursuant to
      paragraph 3.

3.    Except to the extent that the Director shall otherwise specify, the
      statement referred to in paragraph 2 shall include:

      (a)   a schedule of charges for transport of electricity under use of the
            Scottish interconnection;

      (b)   the charge for maintaining voltage and frequency within statutory
            limits;

      (c)   a schedule of the adjustment factors to be made in respect of
            transmission losses, in the form of additional supplies required to
            cover those transmission losses;

      (d)   the methods by which and the principles on which charges (if any)
            will be made for availability of capacity on the Scottish
            interconnection; and

      (e)   such other matters as shall be specified in directions issued by the
            Director from time to time for the purposes of this Condition.

4.    In addition to, and without prejudice to, the Licensee's obligations under
      paragraph 2, the Licensee shall, upon being directed to do so in
      directions issued by the Director from time to time for the purposes of
      this Condition and within such period as shall be specified in the
      directions, prepare a statement approved by the Director providing that
      charges for use of the Scottish interconnection will be made on such basis
      as shall be specified in the directions and such statement shall be in
      such form and contain such detail as shall be necessary to enable any
      person to make a reasonable estimate of the charges to which it would
      become liable for use of the Scottish interconnection and (without
      prejudice to the foregoing) including such information as shall be
      specified in the directions. Each statement prepared in accordance with
      this paragraph shall, with effect from the date on which it is approved by
      the Director or such later date as the Director shall specify, replace the
      corresponding statement prepared by the Licensee in accordance with
      paragraph 2 or, as the case may be, this paragraph (as from time to time
      revised in accordance with paragraph 5) which is in force at such date and
      the Licensee shall, with effect from such date, make charges for use of
      the Scottish interconnection in accordance with the statement (as from
      time to time revised in accordance with paragraph 5) which has replaced
      such corresponding statement.

5.    The Licensee may periodically revise the statement prepared in accordance
      with paragraph 2 or, in the event that the Licensee shall have prepared a
      statement in accordance with paragraph 4, that statement or the latest of
      such statements and shall, at least once in every year the Transmission
      Licence is in force, revise such statement in order that the information
      set out therein shall continue to be accurate in all material respects.
      Each such revision shall require to be approved by the Director and shall
      not become effective until approved by the Director.

6.    The Licensee shall as soon as practicable after the Transmission Licence
      has come into force and, in any event, not later than such date as the
      Director shall specify prepare a statement approved by the Director
      showing:

      (a)   the amount of the capacity of the Scottish interconnection which the
            Licensee anticipates will be available for the transfer of
            electricity from Scotland to England and England to Scotland during
            each remaining week of the year ending

      (c)   the Licensee's forecast of the amount of the remainder of the
            capacity of the Scottish interconnection which will be used for the
            transfer of electricity from Scotland to England and from England to
            Scotland during each week referred to in sub-paragraph (a) above;
            and

      (d)   such other matters (if any) as the Director shall specify prior to
            his approval of the statement.

7.    The Licensee shall, as soon as practicable (and, in any event, within such
      period as the Director shall specify) after giving a notification such as
      is referred to in sub-paragraph (a) of paragraph 6 to SHE in respect of
      the year ending on 31 March 1992 and each subsequent year, prepare a
      statement approved by the Director showing the matters referred to in
      sub-paragraphs (a) to (d) of paragraph 6 in respect of that year.

      with paragraph 2 and any statement prepared in accordance with paragraph
      4, and of each revision of such statements in accordance with paragraph 5,
      and of each statement prepared in accordance with paragraphs 6 and 7 and
      with paragraphs 3(a) and 8 of Condition 3B, to the Director.

      statement in accordance with paragraph 5 approved by the Director pursuant
      to such paragraph and of each statement prepared in accordance with
      paragraphs 6 and 7 to any person who requests a copy of such statement.

      accordance with paragraphs 3(a) and 8 of Condition 3B to any person who
      requests a copy of such statement.

11.   The Licensee may make a charge for any statement given or sent pursuant to

      providing such a statement which shall not exceed the maximum amount
      specified in directions issued by the Director for the purposes of this

      provide an estimate of its reasonable costs in the preparation of any
      statement referred to in paragraph 10, and its obligation to provide such
      statement shall be conditional on the person requesting such statement
      agreeing to pay the amount estimated or such other amount as the Director
      may, upon the application of the Licensee or the person requesting such
      statement, direct.

Condition 3A. Non-discrimination in the provision of use of the Scottish
interconnection

1.    In the provision of use of the Scottish interconnection the Licensee shall
      not discriminate:

      (a)   between any person or class or classes or persons; or

      (b)   between the Licensee (in the provision of use of the Scottish
            interconnection by the Licensee as part of the Transmission Business
            to itself for the purpose of the Supply Business, Second Tier Supply
            Business or Wholesaling Business) and any person or class or classes
            of persons.

2.    Without prejudice to paragraph 1, and subject to paragraph 3, the Licensee
      shall not make charges for the provision of use of the Scottish
      interconnection to any person or class or classes of persons which differ
      from the charges for such provision:

      (a)   to any other person or class or classes of persons; or

      (b)   to the Licensee (in the provision of use of the Scottish
            interconnection by the Licensee to itself for the purposes of the
            Supply Business, Second Tier Supply Business or Wholesaling
            Business);

      except insofar as such differences reasonably reflect differences in the
      costs associated with such provision.

3.    Notwithstanding paragraphs 1 and 2, the Licensee shall not make charges
      for use of the Scottish interconnection in respect of any item of charge
      separately identified in any statement such as is referred to at
      paragraphs 2 and 4 of Condition 3 on any person whose contract does not
      provide for it to receive the service to which such item of charge refers.

5.    The Licensee shall:

      (a)   comply with and perform its obligations under the Interconnector
            Agreement;

      (b)   exercise its rights and perform its obligations under the
            Interconnector Agreement in a manner which is designed to facilitate
            the carrying out of Upgrades proposed by SHE pursuant to the
            Interconnector Agreement (but, for the avoidance of doubt, so that
            the Licensee shall have no obligation to participate in any Upgrade
            proposed by SHE);

      (c)   not exercise or perform such rights or obligations in a manner which
            is designed to have the effect of inhibiting or preventing
            competition in the supply of electricity from Scotland to England or
            from England to Scotland; and

      (d)   not exercise or perform its rights or obligations under any related
            document in a manner which is designed to have the effect referred
            to in sub-paragraph (c) above.

6.    The Licensee shall not be in breach of this Condition or Conditions 3, 3B
      or 3C by reason only of a failure to do or not do any thing which it is
      prevented from doing or not doing by reason of a failure by SHE to comply
      with and perform its obligations under the Interconnector Agreement or by
      a party to a related document or a person who is obliged to comply with a
      related document to comply with and perform its obligations under the
      related document in question.

7.    The Licensee shall keep and maintain such records concerning the provision
      of use of the Scottish interconnection as are, in the opinion of the
      Director, sufficient to enable the Director to assess whether the Licensee
      is performing its obligations under paragraph 1

      and the Licensee shall furnish to the Director such records (or such of
      these as the Director may require), in such manner and at such times as
      the Director may require.

                                      force and to which the Licensee is a party
                                      or with which the Licensee is obliged to

Condition 3B. Requirement to offer terms

1.    On application made by any person, the Licensee shall (except in a case
      where paragraph 2 applies and subject to paragraph 7) offer to enter into
      an agreement for use of the Scottish interconnection to transport across
      the Scottish interconnection in such quantities and for such periods as
      may be specified in the application, electricity to be provided by or on
      behalf of such person:

      (a)   specifying the charges for use of the Scottish interconnection to be
            paid by the person seeking use of the Scottish interconnection, such
            charges to be referable to the statement referred to at paragraph 2
            or (as the case may be) paragraph 4 of Condition 3 or any revision
            thereof; and

      (b)   containing such further terms as are or may be appropriate for the
            purposes of the agreement.

2.    This paragraph applies in any case where, on the application of the
      Licensee or any person entitled or claiming to be entitled to an offer
      pursuant to an application under paragraph 1, the Director shall determine
      that (having regard to the part of the capacity of the Scottish
      interconnection already contracted to persons other than the Licensee and
      affiliates and related undertakings of the Licensee and the part thereof
      approved by the Director as being reserved to the Licensee and affiliates
      and related undertakings of the Licensee for the purpose of the Supply
      Business, Second Tier Supply Business and Wholesaling Business) the
      capacity of the Scottish interconnection is insufficient to accommodate
      the requirements of the person who has made application for an offer
      pursuant to paragraph 1.

3.    In a case where paragraph 2 applies:

      (a)   the Licensee shall (subject to paragraph 12 of Condition 3), if
            requested by the person who has made application for an offer
            pursuant to paragraph 1 and within such period as the Director shall
            specify in his determination under paragraph 2, prepare a statement
            approved by the Director setting out the basis upon which

            charges will be made for the costs which the Licensee would incur if
            an Upgrade were to be carried out in accordance with the
            Interconnector Agreement to accommodate the requirements of the
            person who has made the application for an offer pursuant to
            paragraph 1, such statement to be in such form and to contain such
            detail as shall be necessary to enable such person to make a
            reasonable estimate of the charges to which he would become liable
            in respect of the Upgrade; and

      (b)   following the preparation of a statement under sub-paragraph (a)
            above, the Licensee shall, on the application of the person who has
            made the application for an offer pursuant to paragraph 1, offer to
            enter into:

            (i)   an agreement pursuant to which the Licensee undertakes to
                  exercise its rights under the Interconnector Agreement to
                  require the carrying out of an Upgrade; and

            (ii)  an agreement such as is referred to in paragraph 1, but so
                  that the Licensee shall not be bound to make use of the
                  Scottish interconnection available pursuant to such agreement
                  until the time of completion of the Upgrade.

4.    Charges in respect of Upgrades carried out pursuant to an agreement such
      as is referred to in sub-paragraph (b)(i) of paragraph 3 will be set at a
      level which will enable the Licensee to recover:

      (a)   the appropriate proportion of the costs directly incurred by the
            Licensee in connection with Upgrades; and

      (b)   a reasonable rate of return on the capital represented by such
            costs.

5.    For the purpose of determining an appropriate proportion of the costs
      directly incurred in connection with an Upgrade, the Licensee shall have
      regard to:


Scottish Power                         252                           August 1998

      (a)   the benefit (if any) to be obtained or likely in the future to be
            obtained by the Licensee or any other person from the increase in
            the capacity of the Scottish interconnection resulting from the
            Upgrade; and

      (b)   the ability or likely future ability of the Licensee to recoup a
            proportion of such costs from third parties.

6.    The Licensee shall offer terms for agreements in accordance with paragraph
      1 and paragraph 3(b) as soon as practicable and (save where the Director
      consents to a longer period) in any event not more than the period
      specified in paragraph 9 after receipt by the Licensee of an application
      containing all such information as the Licensee may reasonably require for
      the purpose of formulating the terms of the offer.

7.    The Licensee shall not be obliged pursuant to this Condition to offer to
      enter or to enter into any agreement:

      (a)   if to do so would involve the Licensee:

            (i)   in breach of its duties under Section 9 of the Act; or

            (ii)  in breach of the Electricity Supply Regulations 1988 or of any
                  regulations made under Section 29 of the Act or of any other
                  enactment relating to safety or standards applicable to the
                  interconnection; or

            (iii) in breach of the Conditions to which the Transmission Licence
                  is subject; or

      (b)   if the person making the application does not undertake to be bound
            by the terms of any code of general application or agreement between
            the Licensee and any co-operator of the interconnection governing
            the operation of and maintenance of the interconnection approved for
            the time being by the Director; or

      (c)   if (in the case of an application for an agreement for use of the
            Scottish interconnection to transport electricity from the Southern
            Delivery Point) the electricity to be so transported is to be
            transported from the northern end of the Scottish interconnection to
            the Combined Delivery Point under an agreement for use of the
            Licensee's Transmission System or Distribution System; or

      (d)   if (in the case of an application for an agreement for use of the
            Scottish interconnection to transport electricity to the Southern
            Delivery Point) the electricity to be so transported is to be
            transported from the Combined Delivery Point to the northern end of
            the Scottish interconnection under an agreement for use of the
            Licensee's Transmission System or Distribution System.

8.    If so requested by any person, the Licensee shall (subject to paragraph 12
      of Condition 3), as soon as practicable and in any event not later than
      the expiry of such period as the Director, on the application of the
      person making the request, shall determine for this purpose, give or send
      to such person a statement approved by the Director setting out the basis
      upon which charges will be made for the costs which the Licensee would
      incur if an Upgrade were to be carried out in accordance with the
      Interconnector Agreement to accommodate the requirements of such person as
      specified in the request, such statement to be in such form and to contain
      such detail as shall be necessary to enable such person to make a
      reasonable estimate of the charges to which it would become liable in
      respect of the Upgrade.

9.    For the purpose of paragraph 1, the period specified shall be 28 days. For
      the purpose of paragraph 3(b), the period specified shall be 3 months.

10.   The Licensee shall within 28 days following receipt of a request from any
      person, give or send to such person such information in the possession of
      the Licensee as may be reasonably required by such person for the purpose
      of completing paragraph 8 of Part 1 and paragraphs 2(v) and (vi) of Part 2
      of Schedule 2 to the Electricity (Application for Licences and Extensions
      of Licences) Regulations 1990 or such provisions to like effect contained

Condition 3C. Functions of the Director

1.    If, after a period which appears to the Director to be reasonable for the
      purpose the Licensee has failed to enter into an agreement with any person
      entitled or claiming to be entitled thereto pursuant to a request under
      Condition 3B the Director may, on the application of such person or the
      Licensee, settle any terms of the agreement in dispute between the
      Licensee and that person in such manner as appears to the Director to be
      reasonable having (insofar as relevant) regard in particular to the
      following considerations:

      (a)   that such person should pay to the Licensee charges determined in
            accordance with Conditions 3, 3A and 3B; and

      (b)   that the performance by the Licensee of its obligations under the
            agreement should not involve it in such a breach as is referred to
            in paragraph 7 of Condition 3B;

      (c)   that the obligations of the Licensee under the agreement should not
            be in conflict with the provisions of the Interconnector Agreement
            or any relevant document for the time being approved by the
            Director; and

      (d)   that the terms and conditions of the agreement so settled by the
            Director and of any other agreements entered into by the Licensee
            pursuant to a request under Condition 3B should be, so far as
            circumstances allow, in as similar a form as is practicable.

2.    If the person wishes to proceed on the basis of the agreement as settled
      by the Director, the Licensee shall forthwith enter into and implement
      such agreement in accordance with its terms.

3.    If the Licensee proposes to vary the contractual terms of any agreement
      entered into pursuant to Condition 3B or this Condition in any manner
      provided for under such agreement, the Director may, at the request of the
      Licensee or other party to such agreement, settle any dispute relating to
      such variation in such manner as appears to the Director to be reasonable.

      column 2 of the Table which is a domestic prepayment tariff,

      (a)   the standing charge and the unit charge at the beginning of the
            ninth relevant year shall each be lower than the standing charge and
            unit charge respectively set against that tariff in column 5 of the

2.8.3 In giving consent the Director shall have regard in particular but not
      exclusively to the impact of significant movements in costs outside the
      Licensee's control, and shall consider whether such movements in costs
      justify an increase in all tariffs, a differential increase in tariffs or
      an increase in some tariffs only.

      incorporated in the prices to be charged by the Licensee to Designated
      Customers, the Licensee shall give notice of the new rate to the Director

       regulated unit supplied (as those terms are defined in the form of
       licence in force 31 March 1998) assumed for the purpose of setting the
       prices in column 5 of the Table, the Director may give a direction to the

       tariffs described in column 2 of the Table.

       content of any such direction, the Director shall have regard

      (a)   to the extent to which the regulated supply revenue for the eighth
            relevant year assumed for the purpose of setting the prices in
            column 5 of the Table differs from the actual regulated supply
            revenue for that year adjusted

2.11.3 In considering whether to give any such direction, and in considering the
       content of any such direction, the Director shall have regard

      (a)   to the extent by which the charges made by the Distribution Business
            to the Supply Business have been reduced on account of the terms
            TA(dt) or GA(dt) (or both of them) having a greater value than 0;

       subsequent relevant year, unless the Director has consented in writing,
       each component of each tariff described in colunm 2 of the Table or
       approved for the purpose of paragraph 2.2 shall have a price no greater
       than the price at the end of the immediately preceding relevant year, in
       each case reduced by the formula

       not exclusively to the impact of significant movements in costs outside

4.    Restriction of distribution charges

      Basic Formula

4.1   Without prejudice to paragraph 7, the Licensee shall in setting its
      charges for the provision of distribution services use its best endeavours
      to ensure that in any relevant year the average charge per regulated unit
      distributed shall not exceed the maximum average charge per unit
      distributed calculated in accordance with the following formula:

                         M(dt) = P(dt) + PN(dt) - K(dt)

4.2   For the purposes of paragraph 4.1, M(dt) means the maximum average charge
      per unit distributed in relevant year t.

      Formula for P(dt) as used in paragraph 4.1

4.3   For the purposes of paragraph 4.1, P(dt) is derived from the following
      formula:


            P(dt)=((PU+PM). GR(t).PID(t)) + (PL.(AL(t)-L(t)).PIL(t))

4.6.2 Adjusted distribution losses L(t) means in respect of relevant year t the
      difference between adjusted grid supply point purchases (calculated as
      provided in paragraph 4.6.3 and 4.6.4) and adjusted units distributed
      (calculated as provided in paragraph 4.6.5), save that for the purposes of
      paragraph 4.6.6, adjusted distribution losses for the 12 month period from
      1 April 1989 shall be derived by applying the initial relevant loss
      percentage (calculated as provided in paragraphs E6 to E8 of Part E of
      Schedule 3 of the public electricity supply licences for England and Wales
      PESs in the form in force on 31 March 1995) to the adjusted units
      distributed in that period.

4.6.3 Adjusted grid supply point purchases shall be obtained by adjusting the
      units metered on entry to the Licensee's distribution system by:

      (a)   excluding that number of units which is equal to the sum of

            (i)   EHV units; and

            (ii)  units distributed by the Licensee for the purpose of supply to
                  premises outside the Licensee's authorised area; and

            (iii) an amount in respect of distribution losses between the grid
                  supply point and the exit point attributable to the units
                  referred to in (i) and (ii) above, as determined in accordance
                  with the schedule of adjustment factors referred to in Part
                  VI, Condition 2, paragraph 5(b); and

      (b) including an amount (in units) to represent the effect of units
          entering the Licensee's distribution system otherwise than at grid
          supply points, being the difference between the number of units so
          entering and the number of units that would have been required to have
          entered at grid supply points in their absence (such later number of
          units calculated

                  adjustment factors referred to at Part VI, Condition 2,
                  paragraph 5(b)).

4.6.4 For so long as units are metered on entry to the Licensee's distribution
      system at bulk supply points instead of at grid supply points, such units
      shall be calculated by:

      (i)   applying the procedures in paragraph 4.6.3 as if all references to
            units metered at grid supply points were to units metered at bulk
            supply points; and

      (ii)  grossing-up units metered at the bulk supply points by the relevant
            grid supply point conversion factor being either:

            (a)   0.5 per cent of the units metered at the bulk supply points;
                  or

            (b)   such other factor to take account of losses occurring between
                  the grid supply points and the bulk supply points as the
                  Licensee may with the prior approval of the Director determine
                  to be appropriate.

4.6.5 Adjusted units distributed shall be obtained by:

      (a)   calculating all units distributed by the Licensee metered during
            relevant year t at exit points on leaving the Licensee's
            distribution system; and

      (b)   deducting therefrom EHV units delivered or deemed to be delivered
            during relevant year t and units distributed during relevant year t
            for the purpose of supply to premises outside the Licensee's
            authorised area; and

      (c)   adding thereto an amount equal to the units consumed during relevant
            year t on the Licensee's premises in the authorised area (insofar as
            not otherwise taken into account in determining units distributed
            under sub-paragraph (a) above).

4.6.6 The allowed distribution losses AL(t) in relevant year t shall be derived:

      (a)   by ascertaining the adjusted units distributed in accordance with
            paragraph 4.6.5;

      (b)   multiplying it by the aggregate of adjusted distribution losses
            (calculated as provided in paragraph 4.6.2) over the preceding
            relevant years (commencing with the 12 month period from 1 April
            1989 or, if the number of preceding relevant years exceeds 10,
            relevant year t-10); and

      (c)   dividing the product by the aggregate of adjusted units distributed
            over the same preceding relevant years.

      Information to be provided to the Director

4.6.7 The Licensee shall by 1 July 1995 furnish to the Director as being one of
      the specified items to be included in the statement referred to at
      paragraph 6.7 a statement showing for each year since 1 April 1990
      adjusted grid supply point purchases, adjusted units distributed and
      adjusted distribution losses.

4.6.8 The Licensee shall, following the end of the sixth relevant year and each
      succeeding relevant year, furnish to the Director, as being one of the
      specified items to be included in the statement referred to at paragraph
      6.7, a statement showing the grid supply point purchases, adjusted units
      distributed and adjusted distribution losses for that relevant year,
      accompanied by the underlying calculations of the adjusted distribution
      losses and (where

4.6.9 Where the Director is satisfied that any statement or underlying
      calculation provided has not been drawn up in conformity with paragraph
      4.6.2 to 4.6.6 above, the Director may issue directions, and the statement
      or underlying calculation shall be adjusted with effect from the date of
      issue of the directions or (subject to paragraph 6.10) such other date as
      may be specified in the directions.

Restriction of distribution charges and of supply charges: adjustments

5.1   It in respect of any relevant year, the average charge per regulated unit
      distributed exceeds the maximum average charge per unit distributed by
      more than 3 per cent, the Licensee shall furnish an explanation to the
      Director and in the next following relevant year the Licensee shall not
      effect any increase in charges for the provision of distribution services
      unless it has demonstrated to the reasonable satisfaction of the Director
      that the average charge per regulated unit distributed would not be likely
      to exceed the maximum charge per unit distributed in that next following
      relevant year.

5.2   It in respect of any 2 successive relevant years, the sum of the amounts
      by which the average charge per regulated unit distributed has exceeded
      the maximum average charge per unit distributed is more than 4 per cent,
      then in the next following relevant year the Licensee shall, if required
      by the Director, adjust its charges such that the average charge per unit
      distributed would not be likely, in the judgment of the Director, to
      exceed the maximum average charge per unit distributed in that next
      following relevant year.

5.3   It in respect of 2 successive relevant years, the average charge per
      regulated unit distributed is less than 90 per cent of the maximum average
      charge per unit distributed, the Director, after consultation with the
      Licensee, may direct that in calculating K(dt) for the purposes of
      paragraph 4.1 in respect of the next

      following relevant year, there shall be substituted for R(dt-1) in the
      formula at that paragraph such figure as the Director may specify being
      not less than R(dt-1) and not more than 0.90 (D(t-1).M(dt-1)).

5.4.1 If, in respect of the eighth relevant year, the average charge per
      regulated unit supplied exceeds the maximum average charge per regulated
      unit supplied (as those terms are defined in the form of licence in force
      on 31 March 1998), but by not more than 1 1/2 per cent, the Licensee shall
      ensure that the excess above the maximum average charge per regulated unit
      supplied, with interest thereon at a rate 2 per cent above the average
      specified rate, shall be paid to all 0.1 MW customers who continue to be
      supplied by the Licensee in the ninth relevant year.

5.4.2 If, in respect of the eighth relevant year, the average charge per
      regulated unit supplied exceeds the maximum average charge per regulated
      unit supplied (as those terms are defined in the form of licence in force
      on 31 March 1998) by more than 1 1/2 per cent, the Licensee shall use all
      reasonable endeavours to return the excess above the maximum average
      charge per regulated unit supplied, with interest thereon at a rate 4 per
      cent above the average specified rate, during the ninth relevant year to
      all 0.1 MW customers supplied by the Licensee in the eighth relevant year.

5.4.3 For the purpose of paragraph 2, no sum payable under paragraph 5.4.1 or
      5.4.2 shall be regarded as paid or payable under a tariff applicable to
      the ninth relevant year or any subsequent relevant year.

5.5   No later than three months after the end of the eighth relevant year, the
      Licensee shall send to the Director a statement accompanied by such
      forecasts, estimates and calculations as may be necessary, showing the
      basis by which the Licensee intends to comply with paragraph 5.4.

            the change is to take effect unless a statement complying with
            paragraph 6.7 in respect of relevant year t-1 has been furnished by
            the Licensee to the Director before the publication of the proposed
            change.

6.2   The relevant time referred to in paragraph 6.1 shall be the date of
      publication of such change.

6.3   If within 3 months of the commencement of any relevant year t the Licensee
      has not provided the aforementioned forecasts pursuant to paragraph 6.1
      for the purpose of such changes in charges as are referred to in paragraph
      6.1, the Licensee shall provide the Director with a written forecast of

            applicable in consequence of the average charge per regulated unit
            distributed in the preceding relevant year t-1 or the 2 preceding
            relevant years t-1 and t-2; and

      (b)   its best estimate as to the relevant correction factor K(dt)
            calculated in accordance with the formula set out in paragraph 4 to
            be applied in calculating the maximum average charge per unit
            distributed in respect of the relevant year t.

7.1   The Licensee may at any time after the commencement of a security period
      give notice in writing to the Director suspending, with effect from the
      date of receipt of the notice by the Director, application of such of the
      public electricity supply charge restriction conditions as may be
      specified in the notice for the unexpired term of the security period.

7.2   At any time during a security period, the Director may (having regard to
      his duties under the Act) by means of directions:

      (a)   suspend or modify for the unexpired term of the security period the
            public electricity supply charge restriction conditions or any part
            or parts thereof; or

      (b)   introduce for the unexpired term of the security period new public
            electricity supply charge restriction conditions

       in either case, so as to make such provision as in the opinion or
       estimation of the Director is requisite or appropriate:

             (i)   to enable the Licensee to recover by means of increased
                   charges an amount estimated as being equal to the Licensee's
                   allowed security costs during such period;

             (ii)  to ensure that such part of the amount referred to in
                   subparagraph (i) above as is estimated as being equal to the
                   Licensee's allowed security costs incurred as costs in the
                   Distribution Business are recovered by means of appropriate
                   equitable increases in the charges made in the Distribution
                   Business;

             (iii) to ensure that such part of the amount referred to in
                   subparagraph (i) above as is estimated as being equal to the

                  Licensee's allowed security costs incurred as costs in the
                  Supply Business, Second-Tier Supply Business and Wholesaling
                  Business respectively are recovered by appropriate equitable
                  increases in the charges made in those Businesses

            and the Licensee shall comply with the terms of any directions so
            issued.

7.3   At any time following a security period, the Director may (following such
      consultation with the Licensee and others as the Director may consider
      appropriate) issue directions suspending or modifying the public
      electricity supply charge restriction conditions or any part or parts
      thereof or replacing such directions as may have been made during the
      security period and introducing such new public electricity supply charge
      restriction conditions as in the opinion of the Director are appropriate
      in all the circumstances (including, at the Director's discretion, an
      appropriate adjustment having regard to any profit gained or foregone by
      the Licensee during the security period), and the Licensee shall comply
      with any directions so issued.

7.4   At any time within 3 months after the issue of directions by the Director
      under paragraph 7.3, the Licensee may serve on the Director a
      disapplication request in respect of such of the public electricity supply
      charge restriction conditions or any part or parts thereof as are
      specified in the request.

7.5   If within 3 months of the receipt by the Director of the disapplication
      request referred to in paragraph 7.4, the Director has either not agreed
      in writing to such disapplication request or has not made a reference to
      the Monopolies Commission under Section 12 of the Act relating to the
      modification of the public electricity supply charge restriction
      conditions, the Licensee may deliver one month's written notice to the
      Director terminating the application of such of the public electricity
      supply charge restriction conditions (or any part or parts thereof) as are
      specified in the disapplication request.

7.6   Subject to paragraphs 7.7 and 7.9, the Licensee shall in any relevant year
      be entitled to recover an aggregate amount equal to the Licensee's allowed
      security costs in that year or (insofar as not previously recovered) any
      previous year by means of appropriate equitable increases in the charges
      made in each of the Distribution, Supply, Second-Tier Supply and
      Wholesaling Businesses.

7.7   Paragraph 7.6 shall not apply insofar as the Licensee's allowed security
      costs:

      (a)   were otherwise recovered by the Licensee; or

      (b)   were taken into account by the Director in setting public
            electricity supply charge restriction conditions by means of
            directions issued under paragraph 7.3.

7.8   The Licensee shall following the end of each relevant year provide to the
      Director, as being one of the specified items to be contained in the
      statement referred to in paragraph 6.7, details in respect of that
      relevant year of:

      (a)   the amount of the Licensee's allowed security costs (on an accruals
            basis);

      (b)   the aggregate amounts charged (on an accruals basis) under paragraph
            7.6 on account of the Licensee's allowed security costs; and

      (c)   the bases and calculations underlying the increases in charges made
            in the Distribution, Supply, Second-Tier Supply and Wholesaling
            Businesses under paragraph 7.6.

7.9   Where the Director is satisfied that the Licensee has recovered amounts in
      excess of the Licensee's allowed security costs, the Director may issue
      directions requiring the Licensee to take such steps as may be specified
      to reimburse customers of or purchasers from the Distribution, Supply,
      Second-Tier Supply and Wholesaling Businesses (as the case may be) for the
      excess amounts charged to them, and the Licensee shall comply with any
      directions so issued

      provided that if the excess amounts relate to the Licensee's allowed
      security costs paid to any authorised electricity operator, the Licensee
      shall not be obliged to make any such reimbursement unless and until it
      has recovered such costs from the relevant authorised electricity
      operator.

7.10  No amounts charged by the Licensee under this paragraph 7 (whether or not
      subsequently required to be reimbursed) shall be taken into account for
      the purpose of applying the public electricity supply charge restriction
      provisions of paragraphs 2, 3 and 4.

7.11  In this paragraph 7:

"Licensee's allowed security costs"

                                          means any cost (whenever arising)
                                          incurred by the Licensee and approved
                                          by the Director as being directly
                                          attributable to actions taken or
                                          omitted to be taken by the Licensee or
                                          by any authorised electricity operator
                                          (as the case may be) in consequence
                                          of:

                                          (i) complying with directions issued

                                          (ii) implementing recommendations of
                                          any committee constituted to advise
                                          the Secretary of State as to matters
                                          related to his power to issue
                                          directions under Section 34 of the Act
                                          which are made to and

                                          accepted by the Secretary of State in
                                          contemplation of circumstances likely
                                          to lead to the issue of directions by

                                          34(3) or 34(4) of the Act;

                                          but for the avoidance of doubt
                                          excluding any cost which forms part of
                                          the Licensee's allowed
                                          transmission-related security costs
                                          (as defined in paragraph 6.8 of

      Licensee requires to be attributed to any part of the market, the Licensee
      shall make that attribution on a basis which ensures that no more than a
      fair proportion of those costs, reflecting the costs incurred by the
      Licensee in supplying that part of the market, are so attributed.

8.2   The following paragraphs are without prejudice to paragraph 8.1.

8.3   Fossil Fuel Levy and payments in lieu thereof

      The fossil fuel levy requiring to be attributed to supplies to Designated
      Customers shall be attributed on the basis of the amount of the levy
      incorporated in the prices actually charged or to be charged by the
      Licensee on supplies to such customers in the relevant year in respect of
      which the attribution falls to be made.

8.4   Distribution losses

      Where an amount (in units) in respect of distribution losses requires to
      be calculated and attributed in respect of EHV units and units distributed
      by the Licensee for the purpose of supply to premises outside the
      Licensee's authorised area, such calculation and attribution shall be made
      consistently with the principles underlying the schedule of adjustment
      factors referred to in paragraph 5(b) in Condition 2 of Part VI.

8.5   Information to be provided by Licensee

      The Licensee shall following the end of each relevant year furnish to the

      calculation of amounts in lieu of the fossil fuel levy and the attribution
      of the fossil fuel levy, amounts in lieu thereof and of distribution
      losses was made in accordance with the provisions of this paragraph
      accompanied (where appropriate) by

      (i)   a statement of the total amounts attributed to Designated Customers
            and other customers; and

      (ii)  an explanation of any changes in the principles of attribution or
            their application (as the case may be) since the issue by the
            Licensee of the last such statement.

8.6   Where the Director is satisfied that the basis of calculation or
      attribution (as the case may be) used by the Licensee is not in conformity
      with paragraph 8.1, the Director may issue directions specifying an
      alternative basis of calculation or attribution, and the basis of
      calculation or attribution by the Licensee (as the case may be) shall be
      adjusted accordingly with effect from the date of issue of the directions
      or (subject to paragraph 6.10) such other date as may be specified in
      those directions.

            of the Distribution Business.

      9.2.5 A service provided as part of the Distribution Business may be
            treated as an excluded service insofar as it consists in the
            provision of services (including metering, electric lines or
            electrical plant) for the specific benefit of any third party
            requesting the same and not made available as a normal part of the

      Director relating to the modification of the public electricity supply
      charge restriction conditions (or any part or parts thereof) specified in

      that the cessation of such public electricity supply charge restriction
      conditions, in whole or in part, operates or may be expected to operate
      against the public interest, the Licensee may within 30 days after the
      publication of the report by the Director in accordance with Section 13 of

2.    Initial restriction of transmission charges

Basic Formula

2.1  Without prejudice to paragraph 6 the licensee shall in setting its charges
for the provision of transmission services use its best endeavours to secure
that in any relevant year the average charge per regulated unit transmitted
shall not exceed the maximum average charge per unit transmitted calculated in
accordance with the following formula:

                              RPI(t) - X(t)
                  T(t) = [1 + -------------] P(t-1) - K(Tt)
                                   100

            where:

            T(t)  means the maximum average charge per regulated unit
            transmitted in relevant year t.

            RPI(t)  means the arithmetic mean of the percentage change (whether
            of a positive or a negative value) in the Retail Price Index between
            that published or determined with respect to each of the months from
            July to December (both inclusive) in relevant year t-1 and that
            published or determined with respect to the same months in the
            relevant year t-2 but in relation to the relevant year commencing on
            1 April 1994 shall have a value equal to 2.5;

            X(T)  means 1.0.

            P(t-1)  means that amount per regulated unit transmitted in relevant
            year t-l which is derived from the following formula:

                                                             RPI(t-1) - X(T)
                                       P(t-1) = P(t-2) [ 1 + _______________ ]
                                                                   100

            but, in relation to the relevant year commencing on 1 April 1994
            P(t-1) shall have a value equal to O.348p, and in relation to the
            relevant year commencing on 1 April 1995 P(t-2) shall have that
            value.

            K(Tt)  means the correction factor per regulated unit (whether of a
            positive or negative value) to be applied to the average price per
            regulated unit transmitted in relevant year t (other than in the
            first relevant year and subject to paragraph 3.3) which is derived
            from the following formula.

                          Q (t-1)(C(t-1) - T(t-1))       I(t)
                  K(Tt) = ________________________ (1 +  ____ )
                                     Q(t)                100

      where:

            Q(t-1)  means the regulated quantity transmitted in relevant year
            t-1, but in relation to the relevant year commencing on 1 April 1995
            and each of the three succeeding relevant years shall have the value
            specified opposite the preceding relevant year in Table 1 below.
<PAGE>

            C(t-1)  means the average charge per regulated unit transmitted in
            relevant year t-1.

            T(t-1)  means the maximum average charge per unit transmitted in
            relevant year t-1.

            Q(t)  means the regulated quantity transmitted in relevant year t,
            but in relation to the relevant year commencing on 1 April 1994 and
            each of the four succeeding relevant years shall have the value
            specified opposite that relevant year in Table 1 below.

I(t) means that interest rate in relevant year t which is equal to, where K(Tt)
(taking no account of I for this purpose) has a positive value and C(t-1)
exceeds T(t-1) by more than 2 per cent, the average specified rate plus 4 or,
where K(Tt)(taking no account of I for this purpose) has a negative value, or
C(t-1) does not exceed T(t-1) by more than 2 per cent the average specified
rate.

3.    Restriction of transmission charges; adjustments

3.1 If, in respect of any relevant year, the average charge per regulated unit
transmitted exceeds the maximum average charge per unit transmitted by more than
3 per cent of the latter, the licensee shall furnish an explanation to the
Director and in the next following relevant year the licensee shall not effect
any increase in charges for the provision of transmission services the revenue
from which is regulated under this Schedule unless it has demonstrated to the
reasonable satisfaction of the Director that the average charge per regulated
unit transmitted would not be likely to exceed the maximum average charge per
unit transmitted in that next following relevant year.

3.2 If, in respect of any 2 successive relevant years, the sum of the amounts by
which the average charge per regulated unit transmitted has exceeded the maximum
average charge per unit transmitted is more than 4 per cent of the maximum
average charge per unit transmitted for the second of these relevant years, then
in the next following relevant year the licensee shall, if required by the
Director, adjust its charges for the provision of transmission services the
revenue from which is regulated under this Schedule such that the average charge
per regulated unit transmitted would not be likely, in the judgment of the
Director, to exceed the maximum average charge per unit transmitted in that next
following relevant year.

3.3 If, in respect of any 2 successive relevant years, the average charge per
regulated unit transmitted is less than 90 per cent of the maximum average
charge per unit transmitted, the Director, after consultation with the licensee,
may direct that in calculating K(Tt) in respect of the next following relevant
year, there shall be substituted for C(t-1) in the formula set out in paragraph
2.1 such figure as the Director may specify being not less than C(t-1) and not
more than 0.90 (T(t-1)).

transmitted, together with its components, in respect of the relevant year t-1
immediately preceding the relevant year in which the change is to take effect
unless a statement complying with paragraph 4.5 in respect of relevant year t-1
has been furnished by the licensee to the Director before the publication of the
proposed change.

4.2 If within 3 months of the commencement of any relevant year t the licensee
has not made any such change in charges as is referred to in paragraph 4.1, the
licensee shall provide the Director with a written forecast of the maximum
average charge per unit transmitted together with its components, in respect of
relevant year t.

4.3 Any forecast or estimate provided in accordance with paragraph 4.1 or 4.2
shall be accompanied by such information as regards the assumptions underlying
the forecast or estimate as may be necessary to enable the Director to be

6.2 At any time during a security period, the Director may (having regard to his
duties under the Act) by means of directions:

      (a) suspend or modify for the unexpired term of the security period the
transmission charge restriction conditions or any part or parts thereof; or

      (b) introduce for the unexpired term of the security period new
transmission charge restriction conditions

in either case, so as to make such provision as in the opinion or estimation of
the Director is requisite or appropriate to enable the licensee to recover by
means of a uniform percentage increase on all charges made in the course of the
Transmission Business an amount estimated as being equal to the licensee's
allowed transmission-related security costs during such period, and the licensee
shall comply with the terms of the directions so issued.

6.3 Subject to paragraphs 6.4 and 6.6, the licensee shall in any relevant year
be entitled to recover an aggregate amount equal to the licensee's allowed
transmission-related security costs in that year or (insofar as not previously
recovered) any previous year, by means of appropriate equitable increases in the
charges made by the licensee in the course of the Transmission Business.

6.4 Paragraph 6.3 shall not apply insofar as such licensee's allowed
transmission-related security costs:

      (a) were otherwise recovered by the licensee; or

      (b) were taken into account by the Director in setting charge restriction
conditions by means of directions issued under paragraph 6.2.

6.5 The licensee shall following the end of each relevant year provide to the
Director details in respect of that relevant year of:

      (a) the aggregate amounts charged under paragraph 6.3 on account of the
licensee's allowed transmission-related security costs; and

      (b) the bases and calculations underlying the increases in charges made by
the licensee in the course of the Transmission Business.

6.6 Where the Director is satisfied that the licensee has recovered amounts in
excess of the licensee's allowed transmission-related security costs, the
Director may issue directions requiring the licensee to take such steps as may
be specified to reimburse customers of the Transmission Business for the excess
amounts charged to them, and the licensee shall comply with any directions so
issued.
<PAGE>

6.7 No amounts charged by the licensee under this paragraph 6 (whether or not
subsequently required to be reimbursed) shall be taken into account for the
purpose of applying the transmission charge restriction provisions of paragraph
2.1.

6.8 In this paragraph 6:

"licensee's allowed transmission-         means any cost allowed by the Director
related security costs"                   (upon receipt of such information,
                                          including a certificate from the
                                          Auditors, as the Director may request)
                                          as being a cost which is directly
                                          attributable to any action taken or
                                          omitted to be taken by the licensee in
                                          its capacity as holder of the
                                          transmission licence for the purpose
                                          of complying with directions issued by
                                          the Secretary of State under Section
                                          34(4) of the Act.

7. Duration of transmission charge restriction conditions

7.1 The transmission charge restriction conditions shall apply so long as the
transmission licence continues in force but shall cease to have effect (in whole
or in part, as the case may be) if the licensee delivers to the Director a
disapplication request made in accordance with paragraph 7.2 and:

      (a) the Director agrees in writing to the disapplication request; or

      (b) their application (in whole or in part) is terminated by notice given
by the licensee in accordance with either paragraph 7.4 or paragraph 7.5.

7.2 A disapplication request shall (a) be in writing addressed to the Director,
(b) specify the transmission charge restriction conditions (or any part or parts
thereof) to which the request relates and (c) state the date (being not earlier
than the date referred to in paragraph 7.3) from which the licensee wishes the
Director to agree that the specified transmission charge restriction conditions
shall cease to have effect.

7.3 Save where the Director agrees otherwise, no disapplication following
delivery of a disapplication request pursuant to this paragraph 7 shall have
effect earlier than the date which is the later of:

      (a) the date occurring 18 months after delivery of the disapplication
request; and

      (b) 31 March 1999.

7.4 If the Director has not made a reference to the Monopolies Commission under
Section 12 of the Act relating to the modification of the transmission charge
restriction conditions before the beginning of the period of 12 months which
will end with the disapplication date, the licensee may deliver written notice
to the Director terminating the application of such of the transmission charge
restriction conditions (or any part or parts thereof) as are specified in the
disapplication request with effect from the disapplication date or a later date.

7.5 If the Monopolies Commission makes a report on a reference made by the
Director relating to the modification of the transmission charge restriction
conditions (or any part or parts thereof) specified in the disapplication
request and such report does not include a conclusion that the cessation of such
transmission charge restriction conditions, in whole or in part, operates or may
be expected to operate against the public interest, the licensee may within 30
days after the publication of the report by the Director in accordance with
Section 13 of the Act deliver to him written notice terminating the application
of such transmission charge restriction conditions (or any part or parts
thereof) with effect from the disapplication date or a later date.

1.   This document illustrates the licence obligations which presently apply
     under the Public Electricity Supply Licence held by Manweb plc. The
     document comprises conditions contained in the original Licence granted on
     26 March 1990 and subsequent modifications made to that Licence.

2.   OFFER wishes to make clear that this is not legally binding document but
     has been produced as a working copy of Manweb plc's PES licence. It is
     hoped that this document accurately reflects the present Licence, but it is
     not a substitute for the original Licence and the subsequent schedules of
     modifications issued to Manweb plc and held by OFFER's library.

Condition 2B.  Availability of resources

1.   The Licensee shall at all times act in a manner calculated to secure that
     it has sufficient management resources and financial resources and
     financial facilities to enable it:

     (a)  to carry on the Supply Business and the Distribution Business; and

     (b)  to comply with its obligations under the Act and this Licence.

2.   The Licensee shall submit a certificate addressed to the Director, approved
     by a resolution of the board of directors of the Licensee and signed by a
     director of the Licensee pursuant to that resolution. Such certificate
     shall be submitted in June 1996 and June of each subsequent year. Each
     certificate shall be in one of the following forms:

     (a)  "After making enquiries, the directors of the Licensee have a
          reasonable expectation that the Licensee will have available to it,
          after taking into account in particular (but without limitation) any
          dividend or other distribution which might reasonably be expected to
          be declared or paid, sufficient financial resources and financial
          facilities to enable the Licensee to carry on the Supply Business and
          Distribution Business for a period of 12 months from the date of this
          certificate."

     (b)  "After making enquiries, the directors of the Licensee have a
          reasonable expectation, subject to what is said below, that the
          Licensee will have available to it, after taking into account in
          particular (but without limitation) any dividend or other distribution
          which might reasonably be expected to be declared or paid, sufficient
          financial resources and financial facilities to enable the Licensee to
          carry on the Supply Business and Distribution Business for a period of
          12 months from the date of this certificate. However, they would like
          to draw attention to the following factors which may cast doubt on the
          ability of the Licensee to carry on the Supply Business and
          Distribution Business...."

     (c)  "In the opinion of the directors of the Licensee, the Licensee will
          not have available to it sufficient financial resources and financial
          abilities to enable the Licensee to carry on the Supply Business and
          Distribution Business for a period of 12 months from the date of this
          certificate."

3.   The Licensee shall submit to the Director with that certificate a statement
     of the main factors which the directors of the Licensee have taken into
     account in giving that certificate.

4.   The Licensee shall inform the Director in writing immediately if the
     directors of the Licensee become aware of any circumstance which causes
     them to no longer have the reasonable expectation expressed in the then
     most recent certificate given under paragraph 2.

5.   The Licensee shall use its best endeavours to obtain and submit to the
     Director with each certificate provided for in paragraph 2 a report
     prepared by its auditors and addressed to the Director stating whether or
     not the auditors are aware of any inconsistencies between, on the one hand,
     that certificate and the statement submitted with it and, on the other
     hand, any information which they obtained during their audit work.

6.   The Licensee shall procure from the holding company of the Licensee a
     legally enforceable undertaking in favour of the Licensee in a form already
     specified by the Director that the holding company will refrain from any
     action, and will procure that every subsidiary of the holding company
     (other than the Licensee and its subsidiaries) will refrain from any
     action, which would then be likely to cause the Licensee to breach any of
     its obligations under the Act or this License. Such undertaking shall be
     obtained by 1 March 1996 and shall remain in force for as long as the
     Licensee remains the holder of this Licence and the giver of the
     undertaking remains the holding company of the Licensee.

7.   The Licensee shall:

     (a)  deliver to the Director evidence (including a copy of such
          undertaking) that the Licensee has complied with the obligation to
          procure an undertaking pursuant to paragraph 6; and

          Licensee become aware that the undertaking has ceased to be legally
          enforceable or that its terms have been breached.

Conditions 3A. Restrictions of distribution charges

Basic Formula

1.   Without prejudice to Condition 3F the Licensee shall in setting its charges
     for the provision of distribution services use its best endeavours to
     ensure that in any relevant year the average charge per unit distributed
     shall not exceed the maximum average charge per unit distributed calculated
     in accordance with the following formula:

                         M(dt) = P(dt) + PN(dt) - K(dt)

2.   For the purposes of paragraph 1, M(dt) means the maximum average charge per
     unit distributed in relevant year t.

Formula for P(dt) as used in paragraph 1

3.   For the purposes of paragraph 1, P(dt) is derived from the following
     formula:


             P(dt) = ((PU+PM) GR(t) PID(t)) + (PL (AL(t)-L(t))PIL(t))
                     ------------------------------------------------
                                      D(t)

     where:

     PU   means the amount set against that term in the part of Annex A to this
          Condition that applies to the Licensee.

     PM   means the amount set against that term in the part of Annex A to this
          Condition that supplies to the Licensee.

     Gr(t)  is derived from the following formula:

        where for the relevant year beginning 1st April 1995 GR(t-1) equals 1.

(SIGMA) means the summation across all regulated distribution unit categories i.

P(oi)   means in respect of each regulated distribution unit category i set out
        in column 1 under that term in the part of Annex A to this Condition
        that applies to the Licensee the value opposite that category in
        column 2.

D(it)   means that number of units in each regulated distribution unit category
        i distributed in relevant year t.

D(it-1) means that number of units in each regulated distribution unit category
        i distributed in relevant year t-1.

C(dt)   means a notional figure, representing the number of customers in the
        authorised area defined (for the purpose of this term C(dt) only) for
        each relevant year, given in the table appearing under that term in the
        part of Annex A to this Condition that applies to the Licensee.

C(dt-1) means the number equal to C(dt) in relevant year t-1.

        in the arithmetic average of the Retail Price Index numbers published or
        determined with respect to each of the six months July to December
        (inclusive) in relevant year t-1 and the arithmetic average of the
        Retail Price Index numbers published or determined with respect to the
        same months in relevant year t-2.

Xd(t)   for any relevant year beginning on or after 1 April 1997, shall equal 3.

PL      means an amount equal to 3.0656p.

AL(t)   means an amount (in units) representing allowed distribution losses in
        relevant year t, being the allowed percentage of the adjusted units
        distributed (calculated as provided in paragraph E5 of Part E of
        Schedule 3) where in respect of each relevant year t, the allowed
        percentage shall equal that percentage which the aggregate of adjusted
        distribution losses (calculated as provided in paragraphs E2 to E5 of
        Part E of Schedule 3) over the preceding relevant years (commencing with
        the twelve-month period form 1st April 1989, or, if the number of
        preceding relevant years exceeds nine, relevant year t-10) bears to the
        aggregate of adjusted units distributed (calculated as aforesaid) over
        the corresponding relevant years save that for this purpose adjusted

Formula for PN(dt) as used in paragraph 1

4.      For the purposes of Paragraph 1, in the ninth and subsequent relevant
        years the term PN(dt) shall be calculated in accordance with the
        following formula:



                      (PS + PR) PIR(t) - TA (dt-1) - GA(dt-1)
             PN(dt) = ----------------------------------------
                                     D(t)

        and for each relevant year t prior to the ninth relevant year PN(dt)
        shall be 0.

        where:

        PS      means an amount equal to (pound)4.87 million for each of the
                ninth to the thirteenth relevant years, and thereafter shall
                be 0.

Condition 3B. Restriction on Supply Charges

Continuation Of Tariffs

1.1  Save where the Director consents in writing to a tariff being discontinued,
     the Licensee shall continue to make available to customers at Designated
     Premises the tariffs listed under the Licensee's name in Annex A to this
     Condition.

1.2  Where a customer at Designated Premises was supplied at the end of the
     eighth relevant year on a tariff listed under the Licensee's name in Annex
     B to this Condition, the Licensee shall continue to offer that tariff to
     that customer at those premises unless the Director consents in writing to
     the Licensee's not doing so.

1.3  The Licensee shall not, without the consent in writing of the Director,
     change the terms (other than price, which shall be regulated in accordance
     with this Condition) of any tariff described in the second column of the
     Table; and the terms to which this prohibition applies include, for
     example, the hours between which particular prices apply and the level of
     consumption at which prices change.

New Tariffs

2.   The Licensee shall not offer to supply any customer at Designated Premises
     on a tariff not shown in the Table unless the terms of that tariff have
     been approved by the Director.

The Price Restraint

3.   Without prejudice to Condition 3F, the prices in the tariffs which apply at
     the beginning of the ninth relevant year to supplies to Desgnated Customers
     shall be set at or below the limit imposed by paragraph 4 and in addition
     at or below each of the limits imposed by paragraph 5 and (where those
     paragraphs apply) by paragraphs 6 and 7.

     year the Licensee shall so set its prices to Designated Customers supplied
     on the tariff numbered 1 in the Table that the total charge for that year
     for a Designated Customer supplied on such a tariff who consumes 3300 units
     in that year shall not exceed

5.2  Without prejudice to Condition 3F, at the beginning of the ninth relevant
     year, the prices to Designated Customers on each of the domestic tariffs in
     the Table other than the tariff numbered 1 shall be so set that, when used
     to determine the value of the terms PUi(t), and PSi(t), they do not cause

          relevant year shall each be lower than the standing charge and unit
          charge respectively set against that tariff in column 5 of the Table

     (b)  there shall at no time be any increase in the amount by which the
          standing charge (including any prepayment meter surcharge) for any
          domestic prepayment tariff exceeds the standing charge for the nearest
          comparable domestic tariff (not being a prepayment tariff).


7.2  The Director may direct which tariff is the nearest equivalent domestic
     tariff for the purpose of this paragraph.


8.1  Without prejudice to paragraph 9 and Condition 3F, no price (whether a
     standing charge or a unit charge) in any tariff shall be increased during
     the ninth relevant year above the price which applies at the beginning of
     the ninth relevant year, unless the Director has consented in writing.

8.2  In giving consent the Director shall have regard in particular but not
     exclusively to the impact of significant movements in costs outside the
     Licensee's control, and shall consider whether such movements in costs
     justify an increase in all tariffs, a differential increase in tariffs or
     an increase in some tariffs only.

9.   If any change is made to the rate of the Fossil Fuel Levy between 1 August
     1997 and 2 April 1998, and whenever any change is made to that rate
     thereafter, every price limit set pursuant to paragraphs 4, 5, 6 and 7.1(a)

10.1 Where, after the end of the eighth relevant year, the Director is satisfied
     that in the eighth relevant year the average charge per unit supplied
     differed from the maximum average charge per unit supplied assumed for the
     purpose of setting the prices in column 5 of the Table, the Director may
     give a direction to her Licensee stipulating the prices to be charged for
     any (or all) of the tariffs described in column 2 of the Table.

10.2 Before giving any such direction, the Director shall consult the Licensee.

10.3 In considering whether to give any such direction, and in considering the

     (a)  to the extent to which the regulated supply revenue for the eighth
          relevant year assumed for the purpose of setting the prices in column

11.2 Before giving any such direction, the Director shall consult the Licensee.

11.3 In considering whether to give any such direction, and in considering the
     content of any such direction, the Director shall have regard

     (a)  to the extent by which the charges made by the Distribution Business
          to the Supply Business have been reduced on account of the terms
          TA(dt) or GA(dt) (or both of them) having a greater value than 0;

Condition 3D. Restriction of distribution charges and of supply charges:
- ------------------------------------------------------------------------
adjustments
- -----------


1.   If, in respect of any relevant year, the average charge per unit
     distributed exceeds the maximum average charge per unit distributed by more
     than 3 per cent, the Licensee shall furnish an explanation to the Director
     and in the next following relevant year the Licensee shall not effect any
     increase in charges unless it has demonstrated to the reasonable
     satisfaction of the Director that the average charge per unit distributed
     would not be likely to exceed the maximum charge per unit distributed in
     that next following relevant year.

2.   If, in respect of any two successive relevant years, the sum of the amounts
     by which the average charge per unit distributed has exceeded the maximum
     average charge per unit distributed is more than 4 per cent, then in the
     next following relevant year the Licensee shall, if required by the
     Director, adjust its charges such that the average charge per unit
     distributed would not be likely, in the judgment of the Director, to exceed
     the maximum average charge per unit in that next following relevant year.

3.   If, in respect of two successive relevant years, the average charge per
     unit distributed is less than 90 per cent of the maximum average charge per
     unit distributed, the Director, after consultation with the Licensee, may
     direct that in calculating K(dt) for the purposes of paragraph 1 of
     Condition 3A in respect of the next following relevant year, there shall be
     substituted for R(dt-1) in the formula at paragraph 1 of Condition 3A such
     figure as the Director may specify being not less than R(dt-1) and not more
     than 0.90 (Dt-1.M(dt-1)).

4.1  If, in respect of the eighth relevant year, the average charge per
     regulated unit supplied exceeds the maximum average charge per regulated
     unit supplied, but by not more than 1 1/2 per cent, the Licensee shall
     ensure that the excess above the maximum average charge per regulated unit
     supplied, with interest thereon at a rate 2 per cent above the average
     specified rate, shall be paid to all 0.1 MW customers who continue to be
     supplied by the Licensee in the ninth relevant year.


Manweb                                115                             April 1998
<PAGE>

4.2  If, in respect of the eighth relevant year, the average charge per
     regulated unit supplied exceeds the maximum average charge per regulated
     unit supplied by more than 1 1/2 per cent, the Licensee shall use all
     reasonable endeavours to return the excess above the maximum average charge
     per unit supplied, with interest theron at a rate 4 per cent above the
     average specified rate, during the ninth relevant year to all 0.1 MW
     customers supplied by the Licensee in the eighth relevant year.

4.3  For the purpose of Condition 3B, no sum payable under paragraphs 4.1 or 4.2
     shall be regarded as paid or payable under a tariff applicable to the ninth
     relevant year or any subsequent relevant year.

5.   No later than three months after the end of the eighth relevant year, the
     Licensee shall send to the Director a statement accompanied by such
     forecasts, estimates and calculations as may be necessary, showing the
     basis by which the Licensee intends to comply with paragraph 4.

6.   The powers exercisable under paragraphs F6 and F8 of Part F of Schedule 3
     in the form of licence in force on 31 March 1998 shall continue to be
     exercisable after that date, but only in respect of a relevant year ending
     before 1 April 1998.

Condition 3E. Information to be provided to the Director in connection with the
- -------------------------------------------------------------------------------
charge restriction conditions
- -----------------------------

1.   Where the Licensee is intending to make any change in charges for the
     provision of distribution services regulated under Condition 3A the
     Licensee shall (unless otherwise agreed by the Director) not later than the
     date of publication of such charges provide the Director with:

     (a)  written forecast of the maximum average charge per unit distributed,
          together with its components, in respect of the relevant year t in
          which such a change is to take effect and in respect of the next
          following relevant year t+1; and

     (b)  a written estimate of the maximum average charge per unit distributed,
          together with its components, in respect of the relevant year t-1
          immediately preceding the relevant year in which the change is to take
          effect unless a statement complying with paragraph 7 in respect of
          relevant year t-1 has been furnished to the Director before the
          publication of the proposed change.

2.   Where, at any time during the eighth relevant year, the Licensee intends to
     change the principles of attribution or any provisional attribution
     specified in a statement already made to the Director or to purchase or
     sell an electricity sale contract, the change or the provisional
     attribution in relation to the purchase or sale shall be specified in a
     written statement signed by a person authorised to sign the statement by
     the directors of the Licensee which statement shall not provide for a
     retrospective change of principles or for any re-attribution of payments
     already made or any payment where the event giving rise to that payment has
     already occurred.

3.   If within three months of the commencement of any relevant year t the
     Licensee has not made any such change in charges as is referred to in
     paragraph 1, the Licensee shall provide the Director with a written
     forecast of the maximum average charge per unit distributed, together with
     its components, in respect of the relevant year t.

<PAGE>

4.   The Director may issue directions providing that any forecast or estimate
     provided in accordance with paragraphs 1, 2 or 3 shall be accompanied by
     such information as regards the assumptions underlying the forecast or
     estimate as may be necessary to enable the Director to be satisfied that
     the forecast or estimate has been properly prepared on a consistent basis.

5.   Subject as provided in sub-paragraph (b) below, not later than six weeks
     after the commencement of each relevant year t, the Licensee shall send to
     the Director a statement as to:

     (a)  whether or not the provisions of Condition 3D are likely to be
          applicable in consequence of the average charge per unit distributed
          in the preceding relevant year t-1 or the two preceding relevant years
          t-1 and t-2; and

     (b)  its best estimate as to the relevant correction factor K(dt) to be
          applied in calculating the maximum average charge per unit distributed
          in respect of the relevant year t.

1.   Not later than 15 January in the ninth and tenth relevant years the
     Licensee shall send to the Director a written estimate of the value of the
     term TA for that year (TA(dt)), together with an estimate of the value of
     each of its component parts, as detailed in paragraph 4 of Condition 3A.

2.   Not later than three months after the end of a relevant year the Licensee
     shall send the Director a statement, in respect of that relevant year,
     showing the specified items referred to in paragraph 9.

3. The statement referred to in the preceding paragraph shall be:

     (a)  accompanied by a report from the Auditors that in their opinion (i)
          such statement fairly presents each of the specified items referred to
          in paragraph 9 in accordance with the requirements of the charge
          restriction conditions and (ii)

               (in each case in the form of licence in force on 31 March 1998)
               which represents other than:

Condition 3F. Allowance in respect of security costs


1.   At any time during a security period, the Licensee may give notice in
     writing to the Director suspending, with effect from the date of receipt of
     the notice by the Director, application of such of the charge restriction
     conditions as may be specified in the notice for the unexpired term of the
     security period.

2.   At any time during a security period, the Director may (having regard to
     his duties under the Act) by means of directions:

     (a)  suspend or modify for the unexpired term of the security period the
          charge restriction conditions or any part or parts thereof; or

     (b)  introduce for the unexpired term of the security period new charge
          restriction conditions

     in either case, so as to make such provision as in the opinion or
     estimation of the Director is requisite or appropriate:

          (i)  to enable the Licensee to recover by means of increased charges
               an amount estimated as being equal to the Licensee's allowed
               security costs during such period;

          (ii) to ensure that such part of the amount referred to in
               sub-paragraph (i) above as is estimated as being equal to the
               allowed security costs incurred by the Licensee as costs in its
               Distribution Business are recovered by means of appropriate
               equitable increases on the charges made by the Licensee in its
               Distribution Business; and

         (iii) to ensure that such part of the amount referred to in
               sub-paragraph (i) above as is estimated as being equal to the
               allowed security costs incurred by the Licensee as costs in its

               increases in the charges made by the Licensee in those
               Businesses.

     and the Licensee shall comply with the terms of any directions so issued.

3.   At any time following a security period, the Director may (following such
     consultation with the Licensee and others as the Director may consider
     appropriate) issue directions suspending or modifying the charge
     restriction conditions or any part or parts thereof or replacing such
     directions as may have been made during the security period and introducing
     such new charge restriction conditions as in the opinion of the Director
     are appropriate in all the circumstances (including at the Director's
     discretion an appropriate adjustment having regard to any profit gained or
     foregone by the Licensee during the security period), and the Licensee
     shall comply with any directions so issued.

4.   At any time within three months after the issue of directions by the
     Director under paragraph 3, the Licensee may serve on the Director a
     disapplication request in respect of such of the charge restriction
     conditions or any part or parts thereof as are specified in the request.

5.   If within three months of the receipt by the Director of the disapplication
     request referred to in paragraph 4, the Director has either not agreed in
     writing to such disapplication request or has not made a reference to the
     Monopolies Commission under Section 12 of the Act relating to the
     modification of the charge restriction conditions, the Licensee may deliver
     one month's written notice to the Director terminating the application of
     the charge restriction conditions (or any part or parts thereof) as were
     specified in the disapplication request.

6.   Subject to paragraphs 7 and 9, the Licensee shall in any relevant year be
     entitled to recover an aggregate amount equal to its allowed security costs
     in that year or (insofar as not previously recovered) any previous year, by
     means of appropriate equitable increases on the charges made by the
     Licensee in each of its Distribution, Supply and Second-Tier Supply
     Businesses.

7.   Paragraph 6 shall not apply in so far as such allowed security costs:

     (a)  were otherwise recovered by the Licensee; or

     (b)  were taken into account by the Director in setting charge restriction
          conditions by means of directions issued under paragraph 3 above.

8.   The Licensee shall following the end of each relevant year provide to the
     Director, as being one of the specified items to be contained in the
     statement referred to at paragraph 8 of Condition 3E, details in respect of
     that relevant year of:

     (a)  the amount of the Licensee's allowed security costs; and

          Licensee's allowed security costs; and

     (c)  the bases and calculations underlying the increases in charges made by
          the Licensee in its Distribution, Supply and Second-Tier Supply
          Businesses under paragraph 6.

9.   Where the Director is satisfied that the Licensee has recovered amounts in
     excess of the allowed security costs, the Director may issue directions
     requiring the Licensee to take such steps as may be specified to reimburse
     customers of or purchasers from the Distribution, Supply and Second-Tier
     Supply Business (as the case may be) for the excess amounts charged to
     them, and the Licensee shall comply with any directions so issued provided
     that if the excess amounts relate to allowed security costs paid to any
     authorised electricity operator, the Licensee shall not be obliged to make
     any such reimbursement unless and until it has recovered such costs from
     the relevant authorised electricity operator.

10.  No amounts charged by the Licensee under this Condition (whether or not
     subsequently required to be reimbursed) shall be taken into account for the
     purpose of applying the charge restriction provisions of Conditions 3A and
     3B.

Condition 3G. Duration of charge restriction conditions

1.   The charge restriction conditions shall apply so long as this licence
     continues in force but shall cease to have effect (in whole or in part, as
     the case may be) if the Licensee delivers to the Director a disapplication
     request made in accordance with paragraph 2 and:

     (a)  the Director agrees in writing to the disapplication request; or

     (b)  their application (in whole or in part) is terminated by notice given

2.   A disapplication request pursuant to this Condition 3G shall (a) be in
     writing addressed to the Director, (b) specify the charge restriction

     (c) state the date from which the Licensee wishes the Director to agree
     that the specified charge restriction conditions shall cease to have
     effect.

3.   Save where the Director otherwise agrees, no disapplication following
     delivery of a disapplication request pursuant to this Condition 3G shall
     have effect earlier than that date which is the later of:

     (a)  a date being not less than 18 months after delivery of the
          disapplication request; and either

2.   The Licensee shall not, and shall procure that any affiliate or related
     undertaking of the Licensee shall not, sell or offer to sell electricity
     under any electricity sale contract to any one relevant purchaser or person
     seeking to become a relevant purchaser on terms as to price which are
     materially more or less favourable than those on which it sells or offers

Condition 4A. Prohibition of discrimination in supply

1.   This Condition applies where the Licensee is in a dominant position in a
     market for the supply of electricity to customers at premises.

2.   Where this Condition applies the Licensee shall not supply or offer to
     supply electricity to customers in any market in which it is dominant on
     terms which are predatory.

3.   Where this Condition applies, but subject to paragraph 4, the Licensee
     (taken together with its affiliates and related undertakings) shall not, in
     supplying or offering terms for the supply of electricity to customers in
     any market in which it is dominant:


     (a)  show undue preference to any person (or class of persons) within such
          market;

     (b)  exercise undue discrimination between any persons (or classes of
          person) within such market; or

     (c)  set terms which are unduly onerous.

4.   Nothing in paragraph 3 shall prohibit the Licensee, within any area or
     class of customers (the "relevant area or class") in respect of which
     there is established competition in the supply of electricity, from
     supplying or offering to supply electricity on terms which are reasonably
     necessary to meet that competition, save that the Licensee (taken together
     with its affiliates and related undertakings) shall not, in supplying or
     offering terms for the supply of electricity:


     (a)  show undue preference to any person (or class of persons) or exercise
          undue discrimination between any persons (or classes of person) within
          the relevant area or class of customers; or

     (b)  set terms in respect of any person (or class of persons) in a market
          in which the Licensee is dominant, save such persons who are within
          the relevant area or class of customers, which are unduly onerous.

5.   For the purposes of this Condition, terms are unduly onerous if the revenue
     from the supply of electricity to customers on those terms:


     (a)  significantly exceeds the costs of that supply; and

     (b)  exceeds such costs to a significantly greater degree than the revenue
          from supply to all other customers of the Licensee (and of its
          affiliates and related undertakings) within the same market exceeds
          the costs of supply to those customers.

6.   For the purposes of this Condition, a market may be defined by reference to
     a geographical area, or to a class of customer or both, save that no market
     defined by reference to Designated Customers shall comprise fewer than
     50,000 such customers.

7.   In determining, for the purposes of this Condition, whether any persons
     constitute a class of person, due regard shall be had to the circumstances
     of supply to such persons including (without limitation) volumes, load
     factors, conditions of interruptibility, location of premises being
     supplied and date and duration of the supply contract.

8.   For the purposes of this Condition, the Director shall determine any
     question as to:


     (a)  whether any area or class of customers constitutes a market for the
          supply of electricity;

     (b)  whether the Licensee is dominant in any market for the supply of
          electricity;

     (c)  whether there is established competition in respect of the supply of
          electricity in any area or to any class of customers; and

     (d)  whether any terms are predatory, having due regard to whether such
          terms:

          (i)  incorporate charges which do not reasonably cover the avoidable
               costs incurred in consequence of supplying the customers in
               question; and

          (ii) are intended or are likely to restrict, distort or prevent
               competition in the supply of electricity.

9.   The Director may determine that the Licensee is dominant in a specified
     market:


     (a)  at any time prior to this Condition coming into force; or

     (b)  having first consulted with the Licensee and such other persons as he
          considers appropriate (and having taken into account any
          representations made to him), at any time after this Condition has
          come into force.

     and where the Director does make such a determination he shall immediately
     notify the Licensee.

10.  Where the Director has notified the Licensee of his determination in
     accordance with paragraph 9 that it is dominant in a specified market, the
     provisions of paragraphs 11 to 16 shall apply in respect of that market.

11.  Where this paragraph applies the Licensee shall, prior to supplying or
     offering to supply electricity under a tariff or Designated Supply Contract
     on any new terms, give to the Director at least 28 days' notice in writing
     of its intention to supply on such terms.

12.  For the purposes of this Condition, a tariff or Designated Supply Contract
     is on "new terms" if:


Manweb                                131                             April 1998

     (a)  it is a form of tariff or Designated Supply Contract under which the
          Licensee has not previously supplied or offered to supply electricity;

     (b)  it is a tariff or Designated Supply Contract in respect of which the
          Licensee is varying the terms as to price; or

     (c)  it is a tariff or Designated Supply Contract in respect of which the
          Licensee is varying any other terms in such a manner as to
          significantly affect the evaluation of that tariff or contract.

13.  Where the Licensee has given notice to the Director of its intention to
     supply on new terms it shall not supply or offer to supply electricity on
     such terms until either the period of notice given to the Director has
     expired and:

     (a)  the Director has not given or sent to the Licensee a counter-notice
          (the "counter-notice") in accordance with paragraph 14; or

     (b)  prior to the expiry of such period, the Director has informed the
          Licensee that he will not issue a counter-notice in respect of such
          terms.

14.  The Director may issue a counter-notice where, having considered the new
     terms and having had regard to the likely effects of issuing such counter-
     notice (including, but not limited to, the likely effect upon the business
     of the Licensee), he determines that further consideration is required to
     assess whether such terms are in breach of the provisions of this
     Condition.

15.  Where the Director issues a counter notice in respect of any new terms the
     Licensee shall not supply or offer to supply electricity on such terms
     until either:


     (a)  a period of 3 months from the date of the counter-notice has expired;
          or


                                      132                             April 1998

     (b)  prior to the expiry of such period, the Director indicates to the
          Licensee that he has no present intention of taking enforcement action
          under Section 25 of the Act in respect of such terms.

16.  Where the Director issues a counter-notice he may:


     (a)  give or send a copy of that counter-notice to any Interested Person;

     (b)  invite representations from Interested Persons as to the matters to
          which the counter-notice relates; and

     (c)  require the Licensee, within a reasonable period determined by the
          Director, to provide him with such further information relating to the
          new terms as he may specify (save that he may not virtue of this
          paragraph require the Licensee to furnish him with information for the
          purpose of exercising his functions under Section 48 of the Act),

     and the Director shall take into account any representations made to him by
     the Licensee in respect of such terms.

17.  The Director may, at any time after notifying the Licensee of his
     determination in accordance with paragraph 9 that it is dominant in a
     specified market, determine that the Licensee is no longer dominant in that
     market, and where he does make such a determination:

     (a)  the Director shall immediately notify the Licensee; and

     (b)  the provisions of paragraphs 11 to 16 shall cease to apply in respect
          of the specific market.

18.  For the purposes of this Condition, any reference to the Licensee being

Condition 4B. Duration of discrimination conditions

1.   Condition 4A shall cease to have effect (in whole or in part, as the case
     may be) if the Licensee makes a disapplication request in accordance with
     this Condition and:

     (a)  the Director agrees in writing to that request; or

     (b)  the application of Condition 4A (in whole or in part) is terminated by
          notice given by the Licensee in accordance with paragraph 4 or 5 of
          this Condition.

2.   A disapplication request pursuant to this Condition may be made by the
     Licensee only where the Director has notified it, in accordance with
     paragraph 9 of Condition 4A, of his determination that the Licensee is
     dominant in a specified market, and any such request shall:

     (a)  be made in writing to the Director;

     (b)  specify whether the request relates to the whole of Condition 4A or
          any part or parts thereof; and

     (c)  state the date (the "disapplication date") from which the Licensee
          wishes the specified provisions of Condition 4A to cease to have
          effect, which date shall be in accordance with paragraph 3 and not
          earlier than 12 months after the date on which the request is made.

3.   Where the Licensee was notified by the Director prior to this Condition
     coming into force of his determination that the Licensee is dominant in a
     specified market, no disapplication request made by the Licensee shall be
     effective to disapply any of the provisions of Condition 4A prior to 31
     March 2000.

4.   If the Director has not by the date which is 6 months prior to the
     disapplication date made a reference to the Monopolies Commission (under
     Section 12 of the Act)

     relating to the modification of Condition 4A, the Licensee may give to the
     Director a notice in writing terminating the application of such of the
     provisions of Condition 4A as are specified in the disapplication request
     with effect from the disapplication date or from any later date specified
     in the notice.

5.   If the Monopolies Commission reports on a reference made by the Director
     relating to the modification of Condition 4A and does not conclude that the
     disapplication of any of the provisions of that Condition (being provisions
     specified in the disapplication request) would or may be expected to
     operate against the public interest, the Licensee may within 30 days of the
     publication of the report under Section 13 of the Act give to the Director
     notice in writing terminating the application of such provisions with
     effect from the disapplication date or any later date specified in the

Condition 5. Obligation on economic purchasing

1.   Subject to paragraph 6, the provisions of paragraph 2 shall apply
     separately in relation to purchases of electricity from the following
     sources:

     (a)  qualifying renewable generation;

     (b)  qualifying non-fossil generation; and

     (c)  generation from any source other than as referred to in sub-paragraphs
          (a) and (b) above.

2.   In respect of each category referred to in paragraph 1 above, and subject
     to paragraph 4 below, the Licensee shall:

     (a)  itself purchase;

     (b)  procure any affiliate of the Licensee (other than any member of the
          ScottishPower Group) to purchase; and

     (c)  in so far as it is able through the exercise of voting rights or
          otherwise to do so, procure any related undertaking of the Licensee or
          any defined undertaking to purchase

     electricity at the best effective price reasonably obtainable having regard
     to the sources available.

3.   In determining the effective price at which electricity is purchased by the
     Licensee or any affiliate or related undertaking of the Licensee or any
     defined undertaking, regard shall be had to any payments made or received
     or to be made or received for the grant of or pursuant to any electricity
     purchase contract.

4.   In the discharge of its obligations under paragraph 2 above, the Licensee
     may additionally have regard to any considerations liable to affect its
     ability and that of any affiliate of the Licensee to discharge its
     obligations under this Condition in the future, including the future
     security, reliability and diversity of sources of electricity available for
     purchase.

5.   In this Condition (and subject to paragraph 6) references to qualifying
     renewable generation and to qualifying non-fossil generation shall refer to
     generation from capacity of that description which:

     (a)  has been contracted by the Licensee or any defined undertaking under
          an arrangement certified by the Secretary of State under Section 32(7)
          of the Act which was entered into prior to the date this License
          enters force; or

     (b)  is available to be contracted under arrangements to be produced to the
          Director in satisfaction of an obligation imposed on the Licensee by
          Order made under Section 32 of the Act after this License enters
          force.

6.   Notwithstanding that generation may previously have been contracted as
     being qualifying renewable generation or qualifying non-fossil generation
     (as the case may be), it shall cease to be so treated to the extent that:

     (a)  the Licensee (or any affiliate or related undertaking of the Licensee
          or any defined undertaking) enjoys contractual freedom to vary or
          discontinue its obligation to purchase such generation; and

     (b)  capacity from which qualifying renewable or non-fossil generation (as
          the case may be) is otherwise contracted by the Licensee or any
          affiliate or related undertaking of the Licensee or any defined
          undertaking is equal to or exceeds the aggregate capacity specified in
          any Orders previously made under Section 32 of the Act and continuing
          in force, as being required to be available to the Licensee at that
          time or in respect of any future period covered by such Orders.

7.   Paragraphs 2, 3 and 4 of this Condition shall apply mutatis mutandis where
     the Licensee exercises a discretion or (by agreement or otherwise) varies
     the terms of an existing contract (whether or not entered into prior to the
     date of entry into force of this Licence) in such a manner as to alter the
     effective price under such contract.

Condition 6. Restriction on own generation capacity

1.   The Licensee shall procure that, with effect from the transfer date, the
     Generation Business of the Licensee is held as a Separate Business by or
     through a wholly-owned subsidiary of the Licensee.

2.   Save with the prior written consent of the Director or in the circumstances
     described in paragraph 3 below, the Licensee shall at all times ensure that
     the sum of the amounts in megawatts (calculated as provided under
     paragraphs 4 and 5 below) represented by the declared net capacity of the
     Licensee's own-generation sets and the appropriate share of the declared
     net capacity of generation sets in which the Licensee has an accountable
     interest shall not exceed 550 megawatts.

3.   Where the Licensee is in breach of paragraph 2 by reason of the acquisition
     of own-generation sets or an accountable interest in other generation sets
     in consequence of the occurrence of a specified event affecting the
     operator or any third party, the Licensee shall forthwith notify the
     Director for the purpose of obtaining such consent as is specified in
     paragraph 2.

4.   For the purposes of calculating the limit under paragraph 2 and subject to
     paragraph 5, there shall be attributed to the Licensee:

          economic interest therein) of the declared net capacity of generation
          sets in which it has an accountable interest, ascertained in such
          manner as the Licensee with the approval of the Director may

     (a)  generation sets in which the Licensee has only an accountable interest
          should more properly be treated as own-generation sets; or

     (b)  own-generation sets should more properly be treated as sets in which
          the Licensee only has an accountable interest; or

     (c)  own-generation sets, or generation sets in which the Licensee has an
          accountable interest, should not be treated as falling in either
          category; or

     (d)  generation sets not declared as sets in which the Licensee has an
          accountable interest, should be treated as generation sets in which
          the Licensee has an accountable interest

     the Director may issue directions to the effect.

6.   For the purpose of this Condition and subject to paragraphs 5 and 9, the

          of the Licensee; or

     (b)  the Licensee or any affiliate of the Licensee is in partnership with

          any joint venture with the operator or with any third party with
          regard to the operator; or

     (c)  the Licensee or any affiliate of the Licensee has (directly or
          indirectly):

          (ii) any beneficial underlying interest in the generation set; or

                    being the own-generation set of another Authorised
                    Electricity Operator or in which such Authorised Electricity
                    Operator has an accountable interest, under arrangements for
                    the exchange of capacity entitlement or supplies of

                    Licensee or its affiliate and such Authorised Electricity

     accountable interest in generation sets of any other Authorised Electricity
     Operator as if the references therein to the Licensee were replaced by
     references to such Authorised Electricity Operator.

8.   References in paragraph 6 to contracts giving entitlements to a share of
     declared net capacity shall include electricity sale or purchase contracts
     where rights under such contract are exercisable by reference to an
     identified generation set or to amounts generated at such set.

          plc or a wholly-owned subsidiary thereof under a licence granted
          pursuant to Section 6 of the Act; or

     (b)  the Licensee's interest arises wholly under the terms of the Pooling
          and Settlement Agreement or (other than as provided in paragraph 8)
          under any electricity purchase or sale contract; or

     (c)  the Licensee's interest arises solely by virtue of arrangements for

          associated with changes in the price of fuel used by the generation
          set during the term of any such contract as is referred to in
          paragraph 6 or 8 above.

10.  The Licensee shall, on each such occasion as it provides to the Director
     separate accounts for the Generation Business pursuant to paragraph 3(b)(i)
     of Condition 2 and at any other time upon request of the Director, provide
     to the Director a statement:

     (a)  confirming compliance with paragraphs 1, 2 and 3 above as at the date
          of the statement and throughout the period since the last such
          statement; and

          megawatts represented by the declared net capacity of own-generation
          sets attributable to the Licensee and the appropriate share of the
          Licensee in the declared net capacity of generation sets in which the
          Licensee has an accountable interest, as at the date of the statement.

     Licensee is not in conformity with paragraphs 4 and 5 above, the Director
     may issue directions specifying an alternative basis of calculation, and
     the basis of calculation by the Licensee shall be adjusted accordingly with
     effect from the date of issue of the directions or such other date as may

Condition 7. Tariffs

1.   The Licensee shall ensure that any tariffs fixed under Section 18 of the
     Act shall be so framed as separately to identify:

     (a)  the use of system element in the Licensee's charges; and

     (b)  the charges in respect of the supply of electricity to tariff
          customers.

2.   Where the Director considers that by reason of the complexity of any such
     tariffs fixed by the Licensee, simplified explanatory statements are
     required or expedient for the understanding of tariff customers, the
     Director may direct the Licensee to draw up such explanatory statements and
     thereafter to publish them with the tariffs to which they relate.

Condition 7A. Arrangements for informing customers on revocation of Licence


1.   The Licensee shall comply with a direction from the Director in the
     following terms where the Director:

     (a)  is, or is aware that the Secretary of State is, about to revoke a
          Licence granted to another Electricity Supplier to supply electricity
          (in this Condition known as the "First Supplier"); and

     (b)  considers that the Licensee is able to supply electricity to the
          customers of the First Supplier without significantly prejudicing the
          supplies of electricity which the Licensee makes or is contracted to
          make.

2.   The Director shall only issue a direction in accordance with paragraph 1
     when the Secretary of State or, as the case may be, the Director has served
     the First Supplier with a notice that he is revoking the First Supplier's
     Licence to supply electricity in accordance with the terms of the First
     Supplier's Licence, or such earlier date as the Director may agree with the
     First Supplier.

3.   A direction issued in accordance with paragraph 1 shall require that the
     Licensee shall, within the period specified by the Director, send a written
     notice in a form approved by the Director to each of the persons or
     premises specified or described in the direction:

     (a)  informing the customer in question that, notwithstanding any contract
          he may have with the First Supplier, the First Supplier is no longer
          supplying him with electricity and has not done so since the
          revocation took effect or, where the notice has been sent before the
          revocation has taken effect, will be no longer supplying him with
          electricity when it takes effect.

     (b)  informing the customer that the customer must from the moment the
          revocation takes effect enter into a new contract for supply with
          another

          Electricity Supplier of the customer's choice, and that he is free to
          request a supply from the Licensee; and

     (c)  setting out the terms upon which the Licensee is prepared to supply
          electricity if requested.

Condition 7B. The Programme Implementation Agreement

1.   The Licensee shall, where the Director has given it a written direction to
     do so, enter into and comply with the Programme Implementation Agreement
     established in accordance with paragraph 4.

2.   The Programme Implementation Agreement shall be concerned with matters
     relating to the effective implementation of trading and other arrangements
     between the Licensee and other Relevant Parties which, in the reasonable
     opinion of the Director following consultation with all Relevant Parties,
     are or are likely to be necessary and appropriate to provide for the
     effective and timely facilitation of competition in the supply of
     electricity.

3.   The Programme Implementation Agreement may include provisions relating to:


     (a)  the operation and management of procedures for the testing, trialing
          and integration of those systems, processes and procedures required to
          facilitate competition in the supply of electricity;

     (b)  the obligations of each of the Relevant Parties in respect of the
          procedures defined under sub-paragraph (a);

     (c)  limitations of the liability of the Licensee and of such other persons
          as are specified in the Agreement in respect of actions taken in
          connection with the Agreement;

     (d)  the provision of information as between Relevant Parties and to other
          persons specified in the Agreement;

     (e)  the determination of the specification of systems, processes and
          procedures to be tested, trialed and integrated in accordance with the
          Agreement, except in those circumstances where the Director considers
          that any of the Relevant

          Parties has entered into another agreement which adequately provides
          for such specification to be otherwise determined;

     (f)  the settling by the Director of disputes between Relevant Parties in
          relation to matters covered by the Agreement; and

     (g)  the establishment of a board (the "Implementation Board"), comprising
          appropriate persons appointed by the Director following consultation
          with the Relevant Parties, which shall:

          (i)  oversee the conduct of the Agreement;

          (ii) advise the Director and the Relevant Parties of any matters upon
               which they may reasonably seek advice in relation to matters
               covered by the Agreement, including the operation and management
               of procedures established under the Agreement; and

         (iii) undertake such other functions as in the reasonable opinion of
               the Director are necessary to provide for the effective and
               timely facilitation of competition in electricity supply.

4.   The Programme Implementation Agreement shall be that established by
     agreement between the Relevant Parties with the approval of the Director
     or, where the Relevant Parties cannot agree (or where in the opinion of the
     Director such agreement is unlikely to be reached within a reasonable
     period) and where:

     (a)  the Director has sent to each of the Relevant Parties a notice (the
          "proposals notice") setting out his own proposals in relation to the
          content of the Programme Implementation Agreement; and

     (b)  following consideration of any comments received from any of the
          Relevant Parties within 21 days of the issue of the proposals notice,
          and having made

<PAGE>

          such changes to his proposals as the Director considers appropriate,
          the Director has given to each of the Relevant Parties a notice
          setting out his final proposals (the "confirmation notice"),

     the Programme Implementation Agreement shall, unless within 7 days of the
     issue of the confirmation notice the parties have reached agreement with
     the approval of the Director as to an alternative, be established in
     accordance with the terms of the Director's confirmation notice.

5.   With regard to the provisions of paragraph 1 to 4, and following
     consultation with the Relevant Parties and with such other persons or
     bodies as appear to the Director to represent the interests of those likely
     to be affected, the Director may issue a direction that specified parts of
     the Relevant Conditions shall take effect at such time and in such cases or
     circumstances as he shall direct.

6.   In issuing a direction in accordance with paragraph 5 the Director shall
     have regard to the need to provide for effective arrangements to facilitate
     competition in the supply of electricity to customers and for the effective
     maintenance of existing trading arrangements in respect of the supply of
     electricity.

7.   This Condition shall cease to be in force on whichever is the latest of the
     following dates:

     (a)  30 September 1998;

     (b)  the date which is 6 months after the latest date upon which any
          provision in accordance with paragraph 3 (but excluding sub-paragraph
          3(c)) ceases to have effect; or

     (c)  such other date as may be agreed between the Director and the
          Licensee.

     Licensee's Distribution System (in each case, as part of the Distribution
     Business) will be made, in all cases in such form and with such detail as

          will be made in circumstances where the electric lines or electrical
          plant to be installed are (at the Licensee's discretion) of greater
          size or capacity than that required for use of system by the person
          seeking connection;

     (d)  the methods by which and the principles on which any charges
          (including any capitalised charge) will be made for maintenance,

          the Licensee's Distribution System or the provision and installation,
          maintenance, repair, and replacement or (as the case may be) removal
          following disconnection of any electric lines, electrical plant or
          meters; and

     soon as practicable and in any event within 28 days (or where the Director
     so approves such longer period as the Licensee may reasonably require
     having regard to the nature and complexity of the request) after the date

     (a)  with the prior consent of the Director omit from any such statement
          any details as to circuit capacity, power flows, loading or other
          information, disclosure of which would, in the view of the Director,
          seriously and prejudicially affect the commercial interests of the
          Licensee or any third party; and

     (b)  omit information the disclosure of which would place the Licensee in
          breach of Condition 12.

     the approval of the Director, alter the form of the statements prepared in

     paragraph 14 of an amount which shall not exceed the amount specified in
     directions issued by the Director for the purposes of this Condition based
     on the Director's estimate of the Licensee's reasonable costs of providing
     such a statement.

16.  The Licensee may within 10 days after receipt of the request provide an
     estimate of its reasonable costs in the preparation of any statement
     referred to in paragraph 10, and its obligation to provide such statement
     shall be conditional on the person requesting such statement agreeing to
     pay the amount estimated or such other amount as the Director may, upon
     application of the Licensee or the person requesting such statement,
     direct.

          or class or classes of persons.

2.   In the provision of use of system the Licensee shall not discriminate:

     (a)  between any Authorised Electricity Operators or class of classes
          thereof, or

          or class or classes thereof; or

     use of system restrict, distort or prevent competition in the generation,

Condition 8C. Requirement to offer Standard Terms of Connection

1.   The Licensee shall, within 28 days after this Condition has come into
     force, prepare and submit to the Director for his approval the standard
     terms of an agreement (the "Standard Terms of Connection") to provide, as
     between the Licensee and any customer, for the retention of an established
     connection at premises which are to be supplied with electricity through
     such a connection.

2.   The Licensee may, subject to the approval of the Director, prepare
     different Standard Terms of Connection for different cases or classes of
     customer or premises, clearly identifying the criteria used to distinguish
     between such cases or classes.

3.   The Licensee shall from time or time, and whenever requested to do so by
     the Director, review the Standard Terms of Connection with a view to
     determining whether any revision should be made to such terms, and in the
     course of the review the Licensee shall consult with the Relevant
     Consumers' Committee, all other public electricity suppliers and all Second
     Tier Suppliers which supply electricity within the authorised area.

4.   At the conclusion of any review in accordance with paragraph 3 the Licensee
     shall submit to the Director:

     (a)  a proposal for the revision of the Standard Terms of Connection (or,
          where the Licensee considers it appropriate in all the circumstances,
          a proposal that no revision should be made to the Standard Terms of
          Connection); and

     (b)  the reasons for its proposal, together with a summary of responses
          received from such parties as were consulted by the Licensee.

5.   A proposal made by the Licensee in accordance with paragraph 4 shall
     require to be approved by the Director and, following such approval in
     writing, the Licensee shall

     accordingly revise (or, as the case may be, shall make no revision to) the
     Standard Terms of Connection.

6.   The Licensee shall, in such manner as will in the opinion of the Licensee
     secure adequate publicity therefor:

     (a)  publish, no later than 31 December 1997, the Standard Terms of
          Connection approved by the Director in accordance with paragraph 1;
          and

     (b)  publish, within 21 days after receiving the approval of the Director,
          any revision to the Standard Terms of Connection in accordance with
          paragraph 5.

7.   The Licensee shall not:

     (a)  subject to paragraph 8, enter into a contract with a customer for the
          supply of electricity to premises which are to be supplied through an
          established connection without at the same time (in respect of such
          premises) entering into an agreement with the customer on the Standard
          Terms of Connection; or

     (b)  do anything to prevent the conclusion of an agreement on the Standard
          Terms of Connection between itself and a customer of any Authorised
          Electricity Operator which is acting as agent for the Licensee in
          accordance with an agreement for use of system.

8.   The Licensee may at any time agree with any person (by way of variation to
     the Standard Terms of Connection) terms for the retention of a particular
     established connection which differ from the Standard Terms of Connection
     where such different terms are appropriate in all the circumstances.

Condition 8D. Functions of the Director

     purpose, the Licensee has failed to enter into an agreement with any person
     entitled or claiming to be entitled thereto pursuant to a request under
     Condition 8B or 8C, the Director may, on the application of such person or
     the Licensee, settle any terms of the agreement in dispute between the

     reasonable having (in so far as relevant) regard in particular to the
     following considerations:

     (a)  that such person should pay to the Licensee:

          (i)  in the case of the provision of top-up or standby supplies or

               charges determined in accordance with paragraph 8 of Condition 8;
               and

               existing connection to the system, the whole or an appropriate
               proportion (as determined in accordance with paragraph 5 of
               Condition 8B) of the costs referred to in sub-paragraph 9(a) of
               Condition 8, together with a reasonable rate of return on the
               capital represented by such costs;

     (b)  that the performance by the Licensee of its obligations under the
          agreement should not cause it to be in breach of those provisions
          referred to at sub-paragraph 7(a) of Condition 8B;

     (c)  that any methods by which the Licensee's Distribution System is
          connected to any other system for the transmission or distribution of
          electricity accord (in so far as applicable to the Licensee) with the
          Distribution Code and with the Grid Code;

     (d)  that the terms and conditions of the agreement so settled by the
          Director and of any other agreements entered into by the Licensee

          as circumstances allow, in as similar a form as is practicable; and

     (e)  in the case of exempt supply services, that the agreement for the
          provision of exempt supply services should make provision for all the
          matters set out at paragraph 5 of Condition 8B.

2.   In so far as any person entitled or claiming to be entitled to an offer
     under Condition 8B or 8C wishes to proceed on the basis of the agreement as
     settled by the Director, the Licensee shall forthwith enter into and
     implement such agreement in accordance with its terms.

3.   If either party to such agreement proposes to vary the contractual terms of
     any agreement for exempt supply services, for the provision of a connection
     or for the modification of an existing connection to the Licensee's
     Distribution System, for the retention of an established connection to such
     Distribution System or for use of system entered into pursuant to Condition
     8B or 8C or under this Condition in any manner provided for under such
     agreement, the Director may, at the request of that party, settle any
     dispute relating to such variation in such manner as appears to the
     Director to be reasonable.

6.   If, after a period which appears to the Director to be reasonable for the
     purpose, the Licensee has failed to enter into an agreement with any person

     settled by the Director, the Licensee shall forthwith enter into and
     implement such agreement in accordance with its terms.

     (c)  that the terms and conditions of the agreement so settled by the
          director and of any other agreements entered into pursuant to a
          request under Condition 11C should be, so far as circumstances allow,
          in as similar a form as is practicable.

2.   In so far as any person entitled or claiming to be entitled to an offer
     under Condition 11C wishes to proceed on the basis of the agreement as
     settled by the Director; the Licensee shall forthwith enter into and
     implement such agreement in accordance with its terms.

3.   If any party to such agreement proposes to vary the contractual terms of
     any agreement for any Metering and Data Services entered into pursuant to
     Condition 11C or this Condition in any manner provided for under such
     agreement, the Director may, at the request of that party, settle any
     dispute relating to such variation in such manner as appears to the
     Director to be reasonable.

          (ii) there is an unremedied breach of such undertaking.

Condition 30. Designated Premises

1.   For the purposes of this Licence, the question whether any premises are
     "Designated Premises" shall be determined in accordance with the provisions
     of this Condition.

2.   Premises are Designated Premises if they are either:

     (a)  Domestic Premises; or

     (b)  premises at which, in the reasonable expectation of the Licensee at
          the time of entering into a contract for the supply of electricity to
          such premises, the normal annual consumption of electricity will
          amount to no more than 12,000 kWh,

          but excluding premises referred to at sub-paragraph (b) which receive
          an unmetered supply, or which are supplied through half-hourly or
          maximum demand metering equipment or under the terms of a multi-site
          contract.

3.   For the purposes of this Condition, a "multi-site contract" is a contract
     for the supply of electricity both to any premises which do not fall within
     the terms of sub-paragraphs 2(a) or (b) and to one or more other premises
     (not being Domestic Premises), all of which premises are owned or occupied
     by:

     (a)  the same person or body of persons whether corporate or unincorporate;
          or

     (b)  an undertaking (the "principal undertaking") and any holding company,
          subsidiary, or subsidiary of the holding company of that principal
          undertaking, or any other undertaking in which the principal
          undertaking has a participating interest.

4.   Any premises supplied by the Licensee which (in accordance with paragraphs
     1 to 3) were not Designated Premises at the time at which the Licensee
     entered into a contract


Manweb                                 240                            April 1998

     for their supply shall, notwithstanding subsequent changes to the nature or
     level of the consumption of electricity at those premises, not become
     Designated Premises for the purposes of this Licence prior to the time at
     which they cease to be supplied by the Licencee.

5.   Any premises supplied by the Licensee which (in accordance with paragraphs
     1 to 3) were Designated Premises at the time at which the Licensee entered
     into a contract for their supply shall cease to be Designated Premises for
     the purposes of this Licence where:

     (a)  they have been continuously supplied by the Licensee for a period of
          at least 12 months and:

          (i)  they are not, or are no longer, Domestic Premises; and

          (ii) it is reasonably to be expected that the normal annual
               consumption of electricity at the premises will amount to more
               than 12,000 kWh; or

     (b)  (not being, or being no longer, Domestic Premises) the premises
          commence receipt of an unmetered supply or a supply through
          half-hourly or maximum demand metering equipment or under the terms of
          a multi-site contract.

6.   In this Condition:

     "maximum demand metering           means metering equipment which is
     equipment"                         capable of recording the demand for
                                        electricity supplied to premises during
                                        the half hour of maximum demand in any
                                        period of supply.

Condition 31. Terms for supply of electricity incompatible with Licence
Conditions

1.   Without prejudice to its rights and obligations under the Act, the Licensee
     shall not enter into, offer to enter into, or enter into a variation of any
     contract for the supply of electricity to a customer at Designated Premises
     otherwise than on terms which comply with the Licensee's obligations under
     the Licence.

2.   The Licensee shall not enforce or take advantage of any term of a contract
     for the supply of electricity to a customer at Designated Premises if the
     inclusion of that term was in breach of the provisions of this Licence.

3.   The Licensee shall not take advantage of the omission of any term from a
     contract for the supply of electricity to a customer at Designated Premises
     if the omission of that term was in breach of the provisions of this
     Licence.

Condition 32. Limitation on requirements for termination fees

1.   Where the Licensee enters into any Designated Supply Contract in the
     circumstances set out at paragraph 2 it may not in such contract provide
     for the payment of any termination fee by the Designated Customer.

2.   Paragraph 1 applies in respect of any Designated Supply Contract entered
     into prior to the date which is 90 days following the earliest date
     specified (and not subsequently withdrawn or varied to a later date) in any
     direction or variation of a direction issued by the Director, pursuant to
     condition 3 of the licence held by any Second Tier Supplier, in relation to
     the supply of electricity to all premises within the authorised area.

Condition 33. Revision of the Contract Terms Conditions

1.   The Director, in accordance with the provisions of this Condition, may from
     time to time review (in whole or in part) the provisions and operation of
     the Contract Terms Conditions in the licences of all Electricity Suppliers
     with a view to establishing whether any revision should be made to the
     Contract Terms Conditions in all such licences.

2.   At the commencement of any review by the Director, the Director shall:

     (a)  give to all Relevant Parties a notice in writing which sets out the
          terms of the review and of any proposals in connection therewith and
          which invites the submission of any representations by a specified
          date (being not less than 28 days after the date of the notice); and

     (b)  publish such notice or an accurate summary of it in a manner which
          will, in the opinion of the Director, secure adequate publicity for
          it.

3.   On receiving from the Director notice of such review the Licensee may
     submit any representations on matters within the terms of the review by the
     date specified in the notice.

4.   As soon as practicable following the completion of any such review, the
     Director shall send to each Relevant Party, and to any person who has made
     representation to him by virtue of the notice published under sub-paragraph
     2(b), a copy of:

     (a)  a report on the outcome of such review;

     (b)  any revisions which he proposes to make, having regard to any
          representations received during such review, to the Contract Terms
          Conditions in the licences of all Electricity Suppliers;

<PAGE>

     (c)  a statement of his reasons for proposing those revisions; and

     (d)  a notice specifying the time (being not less than 28 days from the
          date the Director issues the notice) within which Electricity
          Suppliers which are entitled to supply electricity to Designated
          Premises shall state whether or not they consent to the proposed
          revisions to the Contract Terms Conditions in their licences.

5.   A revision proposed to be made by the Director to the Contract Terms
     Conditions of all Electricity Suppliers may be made only where the Director
     is satisfied that the figures determined in accordance with paragraphs 6
     and 7 (expressed as a percentage) are each not less than 90 per cent.

6.   The figure determined in accordance with this paragraph shall be calculated
     under the following formula:

                                    --- x 100
                                    C+N


     where:

          C=   the number of Designated Premises supplied on contract by
               consenting Electricity Supplies; and

          N=   the number of Designated Premises supplied on contract by
               non-consenting Electricity Suppliers

     as estimated (in each case) by the Director on the basis of the information
     most recently available to him.

7.   The figure determined in accordance with this paragraph shall be calculated
     under the following formula:


Manweb                                 245                            April 1998

                                       C+N

where:

          C =  the number of consenting Electricity Suppliers; and

          N =  the number of non-consenting Electricity Suppliers


     8.   In paragraphs 6 and 7 the expressions "consenting" and
          "non-consenting" refer (as the case may be) to the consent or
          otherwise of Electricity Suppliers which are entitled to supply
          electricity to Designated Premises to the proposed revision to the
          Contract Terms Conditions in their licences.

     9.   Where the Director is satisfied that the figures determined in
          accordance with paragraphs 6 and 7 (expressed as a percentage) are
          each not less than 90 per cent the Director may amend the Contract
          Terms Conditions of the Licensee in accordance with the proposed
          revision.

     10.  No revision made to the Contract Terms Conditions by virtue of this
          Condition may introduce an obligation in respect of any matter other
          than one which:

          (a)  is provided for, or is reasonably ancillary to a matter provided
               for, under the Contract Terms Conditions on the date on which
               such Conditions come into force;

          (b)  concerns the terms of contracts offered or entered into by the
               Licensee for the supply of electricity to Designated Premises; or

          (c)  concerns any dealings with customers by or on behalf of the
               Licensee prior to and for the purpose of offering or entering
               into contracts for the supply of electricity to Designated
               Premises.

Condition 36. Notification of terms

1.   Before entering into any Designated Supply Contract the Licensee shall take
     all reasonable steps to draw the attention of the customer to the Principal
     Terms of the contract.

2.   Where the Licensee has entered into a Designated Supply Contract it shall
     (except where it has already done so) provide the customer within 2 working
     days of the date of the contract with a copy of its full terms and
     conditions.

3.   Subject to paragraph 4 the Licensee shall, at least 30 days before any
     Designated Supply Contract to supply electricity for a specified period is
     due to expire, send to the customer:

     (a)  a written offer to enter into a new contract for supply from the date
          of expiry of the existing contract, drawing the attention of the
          customer to the Principal Terms relevant to that offer.

     (b)  an accurate summary of the Principal Terms of other contracts which
          the Licensee will make available to the customer; and

     (c)  details of how the customer can obtain continuity of supply from the
          Licensee.

4.   Paragraph 3 shall not apply where:

     (a)  the customer has informed the Licensee that he does not wish to
          continue to be supplied by it after the expiry of the existing
          contract; or

     (b)  it is not reasonable in all the circumstances for the Licensee to be
          required to continue to supply that customer and the Licensee has (at
          least 30 days before the contract was due to expire) both notified the
          customer to that effect and

          informed him that he must make arrangements to obtain a supply from
          another Electricity Supplier.

5.   Where a Designated Supply Contract allows for its unilateral variation (in
     any respect) by the Licensee and is so varied to the significant
     disadvantage of the customer, the Licensee shall within 10 days of the
     variation give to the customer written notice:

     (a)  of the variation;

     (b)  of the customer's right to terminate the contract; and

     (c)  of the effect of paragraph 6.

6.   Where a customer gives to the Licensee a valid notice of termination within
     14 days of receiving notice under paragraph 5, the Licensee shall treat the
     variation as ineffective and shall neither enforce nor take advantage of
     it.

7.   Where the Licensee believes that any of its customers no longer occupies or
     is about to vacate Designated Premises to which it supplies electricity, it
     shall as soon as reasonably practicable provide any new occupier of those
     premises with an accurate summary of the Principal Terms of contracts it
     will make available to him.

Condition 37. Security deposits

1.   The Licensee shall not, in respect of the supply of electricity under any
     Designated Supply Contract, require a deposit:

     (a)  where the customer is prepared to be supplied through a prepayment
          meter and it is reasonably practicable in all the circumstances
          (including in particular the risk of loss or damage) for the Licensee
          to provide such a meter; or

     (b)  where it is otherwise unreasonable in all the circumstances to do so.

2.   Any deposit required of a Designated Customer may be 1 1/2 times the value
     of the average quarterly consumption of electricity reasonably expected at
     the relevant premises, or more if that is reasonable in all the
     circumstances.

3.   Where the Licensee requires a deposit of a Designated Customer it shall at
     the same time inform that customer of the effect of paragraphs 5 and 7.

4.   Where the Licensee holds any deposit it shall pay interest, at a rate it
     shall fix from time to time with the approval of the Director, on every sum
     of 50p deposited for every 3 months during which that sum is held.

5.   Subject to paragraph 6, any deposit given by a Designated Customer shall be
     repaid (with interest) by the Licensee.

     (a)  within 14 days where, in the previous 12 months, the customer has paid
          all charges for electricity supplied within 28 days of each written
          demand made; or

     (b)  as soon as reasonably practicable, and in any event within 1 month,
          where the Licensee has ceased to supply the customer and the customer
          has paid all charges for electricity supplied.

<PAGE>

6.   Sub-paragraph 5(a) shall not apply where it is reasonable in all the
     circumstances for the Licensee to retain the deposit.

7.   Any dispute arising under this Condition between the Licensee and a
     Designated Customer may be referred by either party to the Director. The
     Director shall determine any such dispute, following such practice and
     procedure as he considers appropriate.

Condition 38. Termination of contracts on notice


1.   Each Designated Supply Contract shall contain a term allowing the customer
     to terminate such contract at any time by:

     (a)  giving to the Licensee a valid notice of termination; and

     (b)  subject to paragraph 6, paying to the Licensee on demand a termination
          fee.

2.   A notice of termination is valid where it is given at least 28 days in
     advance of the date on which it is to take effect and where, not later than
     that date, the requirements of paragraphs 3 and (unless the Licensee
     expressly agrees to waive it) 4 are satisfied.

3.   The requirement of this paragraph is that either:

     (a)  another Electricity Supplier commences a supply of electricity to the
          relevant premises; or

     (b)  the relevant premises are cut off because the customer at those
          premises has ceased to require a supply.

4.   The requirement of this paragraph is that no charges for electricity
     supplied to the customer (whether at the relevant premises or at any
     premises previously occupied by him), having been demanded in writing prior
     to the notice of termination being given, remain owing to the Licensee more
     than 28 days after that demand was made.

5.   Each Designated Supply Contract shall provide that a notice of termination
     which is not valid shall not be effective to terminate such contract.

6.   A termination fee shall not be demanded of a customer where:

<PAGE>

     (a)  the contract was terminated under any provision of Condition 39;

     (b)  the contract was a contract of indefinite length, and was terminated
          other than during a fixed term period;

     (c)  the Licensee notified the customer, under paragraph 5 of Condition 36,
          of a unilateral variation of the contract and the customer gave notice
          of termination in accordance with paragraph 6 of that Condition; or

     (d)  the contract was a contract to which paragraph 4 of Condition 39
          applied and the Licensee did not, before entering into it, take all
          reasonable steps to draw the attention of the customer to the effect
          of the term set out at that paragraph.

7.   Where a termination fee is payable, it shall be of an amount not greater
     than that which the Licensee may in all the circumstances reasonably
     require.

Condition 39. Termination of contracts in specified circumstances


1.   Each Designated Supply Contract shall provide that the contract will
     terminate:

     (a)  on the date on which the customer ceases to own or occupy the relevant
          premises, having given the Licensee at least 2 working days' notice of
          that date; or

     (b)  where the customer has ceased to own or occupy the premises without
          giving the Licensee at least 2 working days' notice, on the first in
          time of:

           (i) the second working day after he has given notice to the Licensee;

          (ii) the next day on which the meter is due to be read; and

         (iii) the date on which any subsequent owner or occupier enters into a
               contract or tariff agreement for the supply of electricity to the
               premises.

2.   Each Designated Supply Contract shall provide that where it is terminated
     by virtue of a term included in the contract in compliance with paragraph
     1, the customer shall remain liable for any charges for the supply of
     electricity until the date of termination.

3.   Each Designated Supply Contract shall provide that it may be terminated
     immediately by either party at any time after the Director or the Secretary
     of State has revoked this Licence.

4.   Any Designated Supply Contract which:

     (a)  provides for the Licensee to supply electricity for a specified period
          of more than 12 months; or

Manweb                                 258                            April 1998

     (b)  contains an initial fixed term period,


          shall provide that it may be terminated immediately by the customer at
          any time within 5 working days of the date of the contract.

5.   Where a Designated Supply Contract is for both the supply of electricity
     and the provision of goods or services:

     (a)  any reference in the Contract Terms Conditions to its termination is a
          reference to its termination in respect of the supply of electricity
          alone; and

     (b)  on its termination by virtue of any provisions of the Contract Terms
          Conditions, the Licensee may require the customer to give any
          reasonable security for his future compliance with the contract for
          the provision of goods or services.

Condition 40. Assignment of outstanding charges


1.   This Condition shall apply where:

     (a)  the Licensee has commenced the supply of electricity to Domestic
          Premises at which a supply was previously given to its customer by the
          Previous Supplier;

     (b)  the customer has failed to pay, within 28 days of receiving a demand
          in writing, any charges due from him to the Previous Supplier for the
          supply of electricity at those premises;

     (c)  that failure occurred after either the Previous Supplier was informed
          of the change of supplier or the Licensee commenced supply to the
          premises (whichever is the earlier);

     (d)  the Previous Supplier has given written notice to the customer that it
          proposes to assign the debt to the Licensee, which may be entitled to
          reclaim from him its costs in recovering the debt; and

     (e)  the Licensee has received from the Previous Supplier a notice in
          accordance with paragraph 2.

2.   A notice in accordance with this paragraph is one which:

     (a)  is given at least 14 days after the notice referred to at
          sub-paragraph 1(d) and is received by the Licensee within 90 days of
          it commencing a supply to the premises;

     (b)  specifies the amount of the debt which remains unpaid;


Manweb                                 260                            April 1998
<PAGE>

     (c)  states that the Previous Supplier has used all reasonable endeavors to
          recover the debt, which remains unpaid at least 42 days after being
          demanded in writing; and

     (d)  states that the Previous Supplier intends to assign to the Licensee
          the debt, up to a maximum sum of one-third of the value (calculated in
          accordance with the charges of the Previous Supplier to the customer
          immediately before it ceased to supply him) of the average annual
          consumption reasonably expected of the customer.

3.   Where this Condition applies the Licensee shall, within 60 days of
     receiving a notice under paragraph 2 and in consideration of the assignment
     of the debt, pay to the Previous Supplier the sum specified under
     sub-paragraph 2(d) (less, where they cannot be reclaimed from the customer,
     its reasonable costs of recovering that debt).

4.   For the purposes of this Condition, a customer shall not be regarded as
     being in debt to the Previous Supplier to the extent to which that debt is
     genuinely in dispute.

5.   In this Condition:

     "Previous Supplier"                means, in relation to any premises, the
                                        Electricity Supplier which supplied
                                        electricity to those premises
                                        immediately prior to the commencement of
                                        supply by the Licensee.

Condition 41. Modification of provisions under Conditions 38 and 40


1.   In this Condition, the "relevant provisions" are the provisions of
     paragraph 4 of Condition 38 and Condition 40 of this Licence (or any of
     them).

2.   Where the Director considers (having regard to any representations made to
     him) that in any specified class of cases the relevant provisions do not
     fulfil the requirements of paragraph 4, he may direct that they shall
     cease to have effect in that class of cases.

3.   Where a direction under paragraph 2 has been made and the Director
     considers (having regard to any representations made to him) that in the
     specified class of cases the relevant provisions would fulfil the
     requirements of paragraph 4, he may direct that they shall again have
     effect in those cases.

4.   The requirements of this paragraph are that, in the specified class of
     cases, the operation of the relevant provisions:

     (a)  significantly reduces the number of unrecovered debts otherwise to be
          expected; or

     (b)  involves expenditure in debt recovery which is less than the reduction
          in the value of unrecovered debts which it achieves.

5.   Any direction under paragraphs 2 or 3 shall be made by a notice given to
     the Relevant Parties which shall specify:

     (a)  the relevant provisions to which it applies;

     (b)  the class of cases to which it applies; and

     (c)  the date on which it shall have effect (being, in a direction under
          paragraph 3, at least 3 months after the notice is given).

                                        likely to be affected by a revision to
                                        the relevant provisions.

Condition 42. Marketing of electricity to Designated Customers

1.   This Condition applies to the marketing activities of the Licensee in
     respect of the supply or the proposed supply of electricity to the
     Designated Premises.

2.   This Condition shall cease to have effect on a date (the "termination
     date") which shall be 31 March 2000, provided that:

     (a)  if the Director, after consultation with the Licensee, all other
          Electricity Suppliers, the electricity consumers' committee and such
          other persons or bodies as in the opinion of the Director are
          representative of those likely to be affected, gives notice for the
          purposes of this Condition generally:

          (i)  by publishing the notice in such a manner as the Director
               considers appropriate for the purpose of bringing it to the
               attention of persons likely to be affected by it; and

         (ii)  by sending a copy of the notice to all Electricity Suppliers and
               electricity consumers' committees.

          that he considers that the development of competition in electricity
          supply is such as to require the continuation of any part of this
          Condition until such date - not later than two years from the
          termination date - as may be specified in the notice (the "new
          termination date"), then such part of this Condition as may be
          specified in the notice shall continue to apply as if for the
          termination date there were substituted the new termination date; and

     (b)  notice under sub-paragraph (a) may be given on more than one occasion.

          communication with Designated Customers for the purposes of the
          marketing activities of the Licensee:

     (b)  take all reasonable steps to ensure that each such person is trained
          so as to have a sufficient understanding of:

               & Wales; and

         (ii)  the principal Term of Designated Supply Contracts made available

          such that any relevant advice given by him to Designated Customers is
          not misleading;

     (c)  take all reasonable steps to ensure that:

          (i)  a Designated Customer may readily identify the Licensee whenever
               he is contacted by a representative of the Licensee; and

         (ii)  any unsolicited contact made on behalf of the Licensee with any
               Designated Customer takes place at a reasonable time; and

     (d)  take all reasonable steps to ensure that any agents or sub-contractors
          of the Licensee set up equivalent procedures and take equivalent steps
          to those set out at sub-paragraphs (a), (b) and (c).

     engaged in activities leading to the making of contracts between the
     Licensee and customers, and not less than 24 hours nor more than 14 days
     after the date of the contract:

     (a)  use its reasonable endeavors to contact the customer by telephone or
          by letter seeking his confirmation that:

          (i)  he understands that he has entered into an electricity supply
               contract;

         (ii)  he is content to have entered into that contract; and

        (iii)  he is content with the way in which the marketing activities of
               the Licensee were conducted;

     (b)  if in the course of such telephone contact, or within a reasonable
          period of the dispatch of such a letter, the customer indicates that
          he is not content to have entered into the contract and wishes to
          terminate it, take all reasonable steps to ensure that the contract is
          terminated and, where reasonably practicable, that the Licensee does
          not commence a supply to the customer; and

     (c)  if the response of the customer, alone or when considered with the
          responses of other customers, suggests weaknesses in the methods,
          systems of personnel employed or engaged by the Licensee or its agents
          or sub-contractors for the purpose of its marketing activities, ensure
          that all reasonable steps to remedy the matter are taken.

     into an electricity supply contract with the Licensee.

6.   The complaint handling procedures to be established by the Licensee in
     accordance with Condition 23 shall provide in appropriate cases for the
     payment of compensation to Designated Customers adversely affected by
     failure by the Licensee to perform its obligations under this Condition.

          of the Licensee secure adequate publicity for it; and

     (b)  send a copy of it free of charge to any person requesting one.

Schedule 3. Supplementary provisions of the charge restriction conditions

Part A. Principles for Attribution

     General Principles

Al.  Where for the purposes of the charge restriction conditions, a share of
     costs borne by the Licensee requires to be attributed to any part of the
     market, the Licensee shall make that attribution on a basis which ensures
     that no more than a fair proportion of those costs, reflecting the costs
     incurred by the Licensee in supplying that part of the market, are so
     attributed.

A2.  The following paragraphs of this Part of Schedule 3 are without prejudice
     to paragraph Al.

     Fossil Fuel Levy and payments in lieu thereof

A3.  The fossil fuel levy requiring to be attributed to supplies to Designated
     Customers shall be attributed on the basis of the amount of the levy
     incorporated in the prices actually charged or to be charged by the
     Licensee on supplies to such customers in the relevant year in respect of
     which the attribution falls to be made. Amounts in lieu of the fossil fuel
     levy in respect of purchases of electricity other than leviable electricity
     requiring to be calculated and then attributed to supplies to Designated
     Customers in any relevant year for the purposes of Condition 3B shall:

     (a)  be calculated as being such amounts as correspond to the lesser of:

          (i)  the premium actually payable (measured on an accruals basis) by
               the Licensee during the relevant year on purchases of
               electricity other than leviable electricity as representing the
               benefit to the Licensee of being



Manweb                                 275                            April 1998
<PAGE>

               able to treat such electricity as being other than leviable
               electricity for the purposes of Section 33 of the Act and
               Regulations thereunder: and

          (ii) the additional amount that would have been payable (measured on
               an accruals basis) by the Licensee in respect of the fossil fuel
               levy pursuant to Regulations made under Section 33 of the Act had
               such electricity been leviable electricity: and

     (b)  be attributed to supplies to Designated Customers pro rata to the
          amount which the quantity supplied to Designated Customers bears to
          the total quantity supplied (in each case in the relevant year in
          respect of which the attribution falls to be made) or on the basis of
          the amount referred to in paragraph (a) incorporated in the prices
          actually charged or to be charged by the Licensee on supplies to such
          customers in the relevant year in respect of which the attribution
          falls to be made or on such other basis of attribution as the Licensee
          shall previously have agreed with the Director.

     Transmission connection point charges and remote transmission asset
     rentals

A4.  The transmission connection point charges and remote transmission asset
     rentals requiring to be attributed between the regulated quantity
     distributed and other quantities distributed shall be attributed in
     proportion to the transmission connection point and remote transmission
     asset capacity required for the purpose of distributing those quantities.

     Distribution losses

A5.  Where an amount (in units) in respect of distribution losses requires to be
     calculated and attributed in respect of EHV units and units distributed by
     the Licensee for the

Manweb                                 276                            April 1998

     purpose of supply to premises outside the licensee's authorised area, such
     calculation and attribution shall be made consistently with the principles
     underlying the schedule of adjustment factors referred to at sub-paragraph
     (b) of paragraph 3 of Condition 8.

     Information to be provided by Licensee

A6.  The Licensee shall following the end of each relevant year furnish to the
     Director, as being one of the specified items to be included in the

     actual attribution of electricity purchase costs between regulated and
     other customers and reconciling the attribution with any statements made in
     respect of the relevant year under paragraph 2 of Condition 3E, and
     a statement confirming that the calculation of amounts in lieu of the
     fossil fuel levy and the attribution of the fossil fuel levy, amounts in
     lieu thereof, the transmission connection point charges, the remote
     transmission asset rentals and of distribution losses was made in
     accordance with the provisions of this Part of Schedule 3, accompanied
     (where appropriate) by

     (i)  a statement of the total amounts attributed to regulated Designated
          Customers and other customers; and

     (ii) copies of statements prepared under paragraph 2 of Condition 3E and
          an explanation of the basis therefore.

A7.  Where the Director is satisfied that the basis of calculation or
     attribution (as the case may be) used by the Licensee is not in conformity
     with paragraph AI, the Director may issue directions specifying an
     alternative basis of calculation or attribution, and the basis of
     calculation or attribution by the Licensee (as the case may be) shall be
     adjusted accordingly with effect from the date of issue of the directions
     or (subject to paragraph 10 of Condition 3E) such other date as may be
     specified in those directions.

     statement referred to at paragraph 7 of Condition 3E, a statement listing

B3.  Where the Director is satisfied that any premises treated by the Licensee
     as EHV premises should not in conformity with sub-paragraph B1(b) above be
     so treated, the Director may issue directions to that effect, and such
     premises shall cease to be treated as EHV premises from the date of issue
     of the directions or (subject to paragraph 10 of Condition 3E) such other
     date as may be specified in those directions.

     for prepayment may not be treated as an excluded service except the
     provision of prepayment meters as an excluded service by the Distribution
     Business.

Part E. Calculation of factor in respect of distribution losses

E1.  For the purposes of calculation of the terms AL\1\ and L\1\ as used in
     paragraph 1 of Condition 3A shall each be determined for relevant years
     commencing on or 1st April 1995 using the consistent methodological basis
     set out in paragraphs E2 to E5 below.

     Consistent methodological basis for determination of AL\1\ and L\1\

E2.  Adjusted distribution losses shall be determined as being the difference
     between adjusted grid supply point purchases and adjusted units
     distributed.

E3.  Units metered on entry to the Licensee's Distribution System shall be
     adjusted to obtain adjusted grid supply point purchases by:

     (a)  excluding that number of units which is equal to the sum of:

          (i)  EHV units; and

          (ii) units distributed by the Licensee for the purpose of supply to
               premises outside the licensee's authorised area; and

          (iii) an amount in respect of distribution losses between the grid
                supply point and the exit point attributable to the units
                referred to in (i) and (ii) above, as determined in accordance
                with paragraph A5 in Part A of Schedule 3; and

     (b)  including an amount (in units) to represent the effect of units
          entering the Licensee's Distribution System otherwise than at grid
          supply points, being the difference between the number of units so
          entering and the number of units that would have been required to
          have entered at grid supply points in their absence (such latter
          number of units being calculated consistently with the


Manweb                                 285                            April 1998
<PAGE>

          principles underlying the schedule of adjustment factors in respect of
          distribution losses referred to at sub-paragraph (b) of paragraph 3 of
          Condition 8).

E4.  For so long as units are metered on entry to the Licensees Distribution
     System at bulk supply points instead of at grid supply points, such units
     shall be calculated by:

     (i)  applying the procedures in paragraph E3 as if all references to units
          metered at grid supply points were to units metered at bulk supply
          points; and

     (ii) grossing-up units metered at the bulk supply points by the relevant
          grid supply point conversion factor being either:

          (a)  0.5 percent of the units metered at the bulk supply points; or

          (b)  such other factor to take account of losses occurring between the
               grid supply points and the bulk supply points as the Licensee may
               with the prior approval of the Director determine to be
               appropriate.

E5.  Adjusted units distributed shall be obtained by:

          (a)  calculating all units distributed by the Licensee metered at exit
               points on leaving the Licensee's Distribution System; and

          (b)  deducting therefrom EHV units and units distributed for the
               purpose of supply to premises outside the licensee's authorised
               area; and

Manweb                                 286                            April 1998
<PAGE>

          (c)  adding thereto an amount equal to the units consumed on the
               licensee's premises in the authorised area (insofar as not
               otherwise taken into account in determining units distributed
               under sub-paragraph (a) above).



          Initial relevant loss percentage in the term Al\1\

E6.  In the first relevant year, the initial relevant loss percentage in the
     term AL, shall (consistently with the methodology set out in paragraphs
     E2 to E5 above) be determined as being:

     adjusted GSP purchase units less adjusted units distributed
                      adjusted units distributed

     where adjusted GSP purchase units are calculated as provided in paragraph
     E7 and adjusted units distributed are calculated as provided in paragraph
     E8.



E7.  Adjusted GSP purchase units shall be calculated in accordance with the
     procedures successively described in the following sub-paragraphs:

     (a)  the actual losses in each of relevant years t-1, t-2 and t-3 (the
          "historic losses") shall be calculated as the difference in each of
          those years between units purchased at entry points to the Licensee's
          Distribution System and units sold;

     (b)  the historic loss percentage shall be calculated as the proportion
          (expressed as a percentage) which the aggregate historic losses were
          of the aggregate units purchased at entry points to the Licensee's
          Distribution System, in each case over the three relevant years t-1
          to t-3;

     (c)  the total number of units sold in relevant year t-1 shall be grossed
          up by the historic loss percentage ("BSP purchase units"); and


Manweb                                 287                            April 1998
<PAGE>

     (d)  the figure for BSP purchase units resulting from sub-paragraph (c)
          shall be adjusted to obtain adjusted GSP purchase units in accordance
          with the provisions of paragraphs E3 and E4 above.

E8.  Adjusted units distributed shall be calculated by applying the methodology
     of paragraph E5 in respect of those units referred to in sub-paragraphs (a)
     to (c) of paragraph E5 in relevant year t-1.

     Information to be provided to the Director

E9.  The Licensee shall within three months after the entry into force of this
     licence furnish to the Director a statement showing the initial relevant
     loss percentage and the underlying calculations.

E10. The Licensee shall, following the end of each relevant year, furnish to the
     Director, as being one of the specified items to be included in the
     statement referred to at paragraph 7 of Condition 3E, a statement showing
     adjusted distribution losses for that relevant year, accompanied by the
     underlying calculations and (where appropriate) an explanation of any
     changes in the basis of calculation or estimation thereof.

E1l. Where the Director is satisfied that any statement or underlying
     calculation provided has not been drawn up in conformity with paragraphs E2
     to E8 above, the Director may issue directions, and the statement or
     underlying calculation shall be adjusted with effect from the date of issue
     of the directions or (subject to paragraph 10 of Condition 3E) such other
     date as may be specified in the directions.

2.    THE FACILITIES

2.1   Facilities

      (a)   Subject to the terms of this Agreement, the Banks grant to the
            Company the following facilities:

            (i)   prior to the exercise of the Term-out Option, a committed
                  multicurrency revolving credit facility under which the Banks
                  agree to make Revolving Loans to the Company; and

            (ii)  if the Term-out Option is exercised, a committed multicurrency
                  term loan facility under which the Banks agree to make Term
                  Loans to the Company.

      (b)   The Banks shall, when requested by the Company, make to the Company
            Loans up to an aggregate principal amount not exceeding, at any
            time, the Total Commitments at that time.

      (c)   No Bank is obliged to lend more than its Commitment.

2.2   Number of Requests and Drawdowns

      No Request may specify a Drawdown Date which is within three Business
      Day's of another Drawdown Date, although up to three Loans may be made on
      the same day. Subject to the above, any number of Requests may be
      delivered on the same day and/or specifying the same Drawdown Date,
      whether or not the Terms or Interest Periods requested are similar.

2.3   Limits

      (a)   The aggregated Original Sterling Amount of all outstanding Loans
            shall not exceed the Total Commitments.

      (b)   No Bank is obliged to participate if it would cause the Original
            Sterling Amount of its participations in the Loans to exceed its
            Commitment.

2.4   Nature of a Finance Party's rights and obligations

      (a)   The obligations of a Finance Party under the Finance Documents are
            several. Failure of a Finance Party to carry out those obligations
            does not relieve any other Party of its obligations under the
            Finance Documents. No Finance Party is responsible for the
            obligations of any other Finance Party under the Finance Documents.

      (b)   The rights of a Finance Party under the Finance Documents are
            divided rights. A Finance Party may, except as otherwise stated in
            the Finance Documents, separately enforce those rights.

2.5   Change of Currency

      If a change in any currency of a country occurs, this Agreement will be
      amended to the extent the Agent acting reasonably and in consultation with
      the Company specifies to be necessary to reflect the change in currency
      and to put the Banks in the same position, so far as possible, that they
      would have been in if no change in currency had occurred.

      of (pound)25,000,000 and an integral multiple of (pound)5,000,000 (or its

      Optional Currency), no amount of any Term Loan prepaid may subsequently be
      reborrowed. No amount of the Total Commitments cancelled under this
      Agreement may subsequently be reinstated.

8.    INTEREST

8.1   Interest rate

      The rate of interest on each Loan for its Term or Interest Period (as
      appropriate) is the rate per annum determined by the Agent to be the
      aggregate of the applicable:

      (a)   Margin;

      (b)   LIBOR; and

      (c)   Mandatory Cost.

8.2   Interest Periods for Term Loans

      (a)   The life of each Term Loan will be divided into successive periods
            (each an "Interest Period") for the calculation of interest. The
            first Interest Period will be the period selected in the Request for
            that Term Loan, and in the case of a Term Loan that has been
            borrowed, in a Selection Notice received by the Agent not later than
            10.00 a.m. three Business Days before the end of the current
            Interest Period (being one, two, three or six months).

      (b)   If an Interest Period extends beyond the Final Repayment Date, it
            shall be shortened so that it ends on the Final Repayment Date.

      (c)   If the Company fails to select an Interest Period for an outstanding
            Term Loan in accordance with paragraph (a) above, that Interest
            Period will, subject to the other provisions of this Clause 8, be
            one month.

8.3   Non-Business Days

      If an Interest Period would otherwise end on a day which is not a Business
      Day, that Interest Period shall instead end on the next Business Day in
      that calendar month (if there is one) or the preceding Business Day (if
      there is not).

8.4   Due dates

      Except as otherwise provided in this Agreement, accrued interest on each
      Loan is payable by the Company on the last day of its Term or Interest
      Period.

8.5   Default interest

      (a)   If an Obligor fails to pay any amount payable by it under the
            Finance Documents, it shall forthwith on demand by the Agent pay
            interest on the overdue amount from the due date up to the date of
            actual payment, as well after as before judgment, at a rate (the
            "default rate") determined by the Agent to be one per cent. per
            annum above the higher of:

            (i)   the rate on the overdue amount under Clause 8.1 (Interest
                  rate) immediately before the due date (if of principal); and

- --------------------------------------------------------------------------------
<PAGE>

                                       22

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


            (ii)  the rate which would have been payable if the overdue amount
                  had, during the period of non-payment, constituted a Loan in
                  the currency of the overdue amount for such successive Terms
                  or Interest Periods of such duration as the Agent may
                  determine (each a "Designated Term").

      (b)   The default rate will be determined on each Business Day or the
            first day of the relevant Designated Term, as appropriate.

      (c)   If the Agent determines that deposits in the currency of the overdue
            amount are not at the relevant time being made available by the
            Reference Banks to leading banks in the London interbank market, the
            default rate will be determined by reference to the cost of funds to
            the Agent from whatever sources it reasonably selects, after
            consultation with the Reference Banks.

      (d)   Default interest will be compounded monthly (where paragraph (a)(i)
            applies) and at the end of each Designated Term (in each other
            case).

8.6   Notification of rates of interest

      The Agent shall promptly notify each relevant Party of the determination
      of a rate of interest under this Agreement.

9.    OPTIONAL CURRENCIES

9.1   Selection

      (a)   The Company shall select the currency of a Revolving Loan in the
            relevant Request.

      (b)   The Company shall select the currency of a Term Loan for an Interest
            Period in either the relevant Request or, if a Term Loan is
            outstanding, a notice received by the Agent not later than 5
            Business Days' before the commencement of that Interest Period. In
            the latter case, the Company may specify whether that Term Loan is
            to be denominated in more than one currency, and, if so, the amount
            in Sterling of each such currency (being a minimum Original Sterling
            Amount of (pound)25,000,000 or an integral multiple of
            (pound)5,000,000 or the balance of the Term Loan, if more).

      (c)   The currency of each Loan must be Sterling or an Optional Currency.

      (d)   If the Company fails to give a notice in respect of an outstanding
            Term Loan in accordance with paragraph (b) above, that Term Loan
            will remain denominated for its next Interest Period in the same
            currency in which it is then denominated.

      (e)   Each part of a Term Loan which is to be denominated in a different
            currency from any other part of that Term Loan shall be treated as a
            separate Term Loan.

      (f)   The Company may not choose a currency if as a result the Loans would
            be denominated at any time in more than 3 currencies.

      (g)   The Agent shall notify each Bank of the currency and the Original
            Sterling Amount of each Loan and the applicable Agent's Spot Rate of
            Exchange promptly after they are ascertained.

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


9.2   Revocation of currency

      If, before 9.30 a.m. on any Rate Fixing Day, the Agent receives notice
      from a Bank that:

(a)   it is impracticable for the Bank to fund its participation in the relevant
      Loan in the relevant Optional Currency during its Term or Interest Period
      (as appropriate) in the ordinary course of business in the London
      interbank market; and/or

(b)   the use of the proposed Optional Currency might contravene any law or
      regulation,

      the Agent shall give notice to the Company and to the Banks to that effect
      before 11.00 a.m. on that day. In this event:

      (i)   the Company and the Banks may agree that the drawdown will not be
            made; or

      (ii)  in the absence of agreement, that Bank's participation in the Loan
            (or, if more than one Bank is similarly affected, those Banks'
            participations in the Loan) shall be treated as a separate Loan
            denominated in Sterling during the relevant Term or Interest Period
            (as appropriate).

9.3   Change of currency of Term Loan

      (a)   If a Term Loan is to be continued during its next Interest Period in
            a different currency (the "new currency") from that in which it is
            currently denominated, that Term Loan shall be repaid by the Company
            in full at the end of its current Interest Period in the currency in
            which it is then denominated and, subject to the terms of this
            Agreement, shall forthwith be re-advanced by the Banks in the new
            currency.

      (b)   If the new currency is Sterling, the amount of each Bank's
            participation in that Term Loan will be its participation in the
            Original Sterling Amount (as such Original Sterling Amount has been
            reduced by any repayment or prepayment of part of such Loan under
            this Agreement) of that Term Loan for that Interest Period.

      (c)   If the new currency is an Optional Currency, the amount of each
            Bank's participation in that Term Loan will be determined by
            converting into the new currency its participation in the Original
            Sterling Amount (as such Original Sterling Amount has been reduced
            by any repayment or prepayment of part of such Loan under this
            Agreement) of that Term Loan on the basis of the Agent's Spot Rate
            of Exchange three Business Days before the commencement of that
            Interest Period.

9.4   Same Optional Currency

      (a)   If a Term Loan is to be continued during its next Interest Period in
            the same Optional Currency as that in which it is denominated during
            its current Interest Period, the Agent shall calculate the
            difference between the amount of the Term Loan (in that Optional
            Currency) for the current Interest Period and for the next Interest
            Period. The amount of the Term Loan for the next Interest Period
            will be determined by notionally converting into that Optional
            Currency the Original Sterling Amount of the Term Loan on the basis
            of the Agent's Spot Rate of Exchange three Business Days before the
            commencement of that Interest Period.

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


      (b)   At the end of the current Interest Period (but subject always to
            paragraph (c) below):

            (i)   if the amount of the Term Loan for the next Interest Period is
                  less than that of the preceding Interest Period, the Company
                  shall repay the difference in such Optional Currency; or

            (ii)  if the amount of the Term Loan for the next Interest Period is
                  greater than that of the preceding Interest Period, each Bank
                  shall forthwith make available to the Agent for the Company
                  its participation in the difference and the Agent shall pay to
                  the Company the difference in such Optional Currency.

      (c)   If the Agent's Spot Rate of Exchange for the next Interest Period
            shows an appreciation or depreciation of the Optional Currency
            against Sterling of less than five per cent. when compared with the
            Original Exchange Rate, no amounts are payable in respect of the
            difference. In this Clause 9 (Optional Currencies) "Original
            Exchange Rate" means the Agent's Spot Rate of Exchange used for
            determining the amount of the Optional Currency for the Interest
            Period which is the later of the following:

            (i)   the Interest Period during which the Term Loan was first
                  denominated in that Optional Currency if the Term Loan has
                  since then remained denominated in that Optional Currency; and

            (ii)  the most recent Interest Period immediately prior to which a
                  difference was required to be paid under this Clause 9.4.

9.5   Prepayments and repayments

      If a Term Loan is to be repaid or prepaid by reference to an Original
      Sterling Amount, the Optional Currency amount to be repaid or prepaid
      shall be determined by reference to the Agent's Spot Rate of Exchange last
      used for determining the Optional Currency amount of that Term Loan under
      this Clause 9 or, if applicable, the Original Exchange Rate.

10.   PAYMENTS

10.1  Place

      All payments by an Obligor or a Bank under the Finance Documents shall be
      made to the Agent to its account at such office or bank as it may notify
      to the Obligors or that Bank for this purpose.

10.2  Funds

      Payments under the Finance Documents to the Agent shall be made for value
      on the due date at such times and in such funds as the Agent may specify

      of transactions in the relevant currency in the place for payment.

10.3  Distribution

      (a)   Each payment received by the Agent under this Agreement for another
            Party shall, subject to paragraphs (b) and (c) below, be made

            the currency and funds of receipt) to its account with such office
            or bank:

            (i)   in the principal financial centre of the relevant currency; or

            (ii)  in the case of euro units or national currency units, in the
                  principal financial centre of a Participating Member State or
                  London,

            as it may notify to the Agent for this purpose by not less than 5
            Business Days' prior notice.

      (b)   The Agent may apply any amount received by it for an Obligor in or
            towards payment (on the date and in the currency and funds of
            receipt) of any amount due from an Obligor under the Finance
            Documents.

      (c)   Where a sum is to be paid under the Finance Documents to the Agent
            for the account of another Party, the Agent is not obliged to pay
            that sum to that Party until it has established that it has actually
            received that sum. The Agent may, however, assume that the sum has
            been paid to it in accordance with this Agreement and, in reliance
            on that assumption, make available to that Party a corresponding
            amount. If the sum has not been made available but the Agent has
            paid a corresponding amount to another Party, that Party shall
            forthwith on demand refund the corresponding amount to the Agent
            together with interest on that amount from the date of payment to
            the date of refund, calculated at a rate determined by the Agent to
            reflect its cost of funds.

10.4  Currency

      (a)   A repayment or prepayment of a Loan or any part of a Loan is payable
            in the currency in which the Loan is denominated on its due date.

      (b)   Interest is payable in the currency in which the relevant amount in
            respect of which it is payable is denominated.

      (c)   Amounts payable in respect of costs, expenses, taxes and the like
            are payable in the currency in which they are incurred.

      (d)   Any other amount payable under the Finance Documents is, except as
            otherwise provided in this Agreement, payable in Sterling.

10.5  Set-off and counterclaim

      All payments made by an Obligor under the Finance Documents shall be made
      without set-off or counterclaim.

10.6  Non-Business Days

      (a)   If a payment under the Finance Documents is due on a day which is
            not a Business Day, the due date for that payment shall instead be
            the next Business Day in the same calendar month (if there is one)
            or the preceding Business Day (if there is not).

      (b)   During any extension of the due date for payment of any principal
            under this Agreement interest is payable on the principal at the
            rate payable on the original due date.

10.7  Partial payments

      (a)   If the Agent receives a payment insufficient to discharge all the
            amounts then due and payable by the Obligors under the Finance
            Documents, the Agent shall apply that payment towards the
            obligations of the Obligors under the Finance Documents in the
            following order:

            (i)   first, in or towards payment of any unpaid costs and expenses
                  of the Agent under the Finance Documents;

            (ii)  secondly, in or towards payment pro rata of any accrued fees
                  due but unpaid under Clause 20.2 (Commitment fee);

            (iii) thirdly, in or towards payment pro rata of any accrued
                  interest due but unpaid under this Agreement;

            (iv)  fourthly, in or towards payment pro rata of any principal due
                  but unpaid under this Agreement; and

            (v)   fifthly, in or towards payment pro rata of any other sum due
                  but unpaid under the Finance Documents.

      (b)   The Agent shall, if so directed by all the Banks, vary the order set
            out in sub-paragraphs (a)(ii) to (v) above.

      (c)   Paragraphs (a) and (b) above shall override any appropriation made
            by an Obligor.

10.8  Netting of payments

      (a)   If on any date an amount (the "first amount") is to be advanced or
            paid by a Bank under this Agreement and an amount (the "second
            amount") is due from an Obligor to that Bank under the Finance
            Documents, the Obligor instructs that Bank to apply the first amount
            in or towards payment of the second amount.

      (b)   The relevant Bank shall remain obliged to advance any excess (or, as
            the case may be, an Obligor shall remain obliged to pay any
            shortfall) in accordance with this Clause 10. Nothing in this Clause
            10.8 shall be effective to create a charge.

11.   TAXES

11.1  Gross-up

      All payments by an Obligor under the Finance Documents shall be made free
      and clear of and without deduction for or on account of any taxes levied
      or imposed by or on behalf of the UK or any taxing authority thereof or
      therein except to the extent that the Obligor is required by law to make
      payment subject to any taxes. If any tax or amounts in respect of tax must
      be deducted from any amounts payable or paid by an Obligor, or paid or
      payable by the Agent to a Bank, under the Finance Documents, the Obligor
      shall pay such additional amounts as may be necessary to ensure that the
      relevant Bank receives a net amount equal to the full amount which it
      would have received had payment not been made subject to tax.

11.2  Tax receipts

      All taxes required by law to be deducted or withheld by an Obligor from
      any amounts paid or payable under the Finance Documents shall be paid by
      the relevant Obligor when due and the Obligor shall, within 30 days of the
      payment being made, deliver to the Agent for the relevant Bank an original
      or certified copy of an official receipt or such other evidence, if any,
      as is then customary, evidencing that such deduction or withholding has
      been made and has been accounted for to the appropriate authorities.

11.3  Qualifying Banks

      (a)   If, otherwise than as a result of the introduction of, change in, or
            change in the interpretation, administration or application of, any
            law, treaty or regulation or any practice or concession of the UK
            Inland Revenue occurring after the date of this Agreement, a Bank is
            not or has ceased to be a Qualifying Bank or is not or has ceased to
            be beneficially entitled to all interest received by it in respect
            of advances made by it under this Agreement, no Obligor will be
            liable to pay to or for the account of that Bank under Clause 11.1
            (Gross-up) any amount in respect of taxes levied or imposed by the
            U.K. or any taxing authority of or in the UK in excess of the amount
            it would have been obliged to pay if that Bank had been, or had not
            ceased to be a Qualifying Bank and had been beneficially entitled to
            all interest received by it in respect of advances made by it under
            this Agreement.

      (b)   Each Bank warrants and represents to the Obligors on the date of
            this Agreement or (if later) on the date on which it becomes a Party
            that it is a Qualifying Bank and is beneficially entitled to all
            interest receivable by it in respect of advances made by it under
            this Agreement.

      (c)   Each Bank which ceases to be a Qualifying Bank or which ceases to be
            beneficially entitled to interest received by it in respect of
            advances made by it under this Agreement will notify the Company
            forthwith upon becoming aware that it has so ceased.

11.4  Tax Credit

      (a)   If an Obligor makes a payment pursuant to Clause 11.1 (Gross-up) for
            the account of any Bank and that Bank has received or been granted a
            credit against, or relief or remission or repayment of, any tax paid
            or payable by it (a "Tax Credit") which is attributable to that
            payment or the corresponding payment under the Finance Document that
            Bank shall, to the extent that it can do so without prejudice to the
            retention of the amount of such credit, relief, remission or
            repayment, pay to the Obligor concerned such amount as the Bank
            shall have reasonably determined to be attributable to such payments
            and which will leave the Bank (after such payment) in no better or
            worse position than it would have been if the Obligor had not been
            required to make any deduction or withholding.

      (b)   Nothing in this Clause 11.4 shall interfere with the right of a Bank
            to arrange its tax affairs in whatever manner it thinks fit and
            without limiting the foregoing no Bank shall be under any
            obligation, except as expressly stated in sub-clause (a) above, to
            claim a Tax Credit or to claim a Tax Credit in priority to any other
            claims, relief, credit or deduction available to it. No Bank shall
            be obliged to disclose any information relating to its tax affairs
            or any computations in respect thereof.

11.5  Double Tax Treaties

      For the purposes of Clause 11.3(a) above, a financial institution which is
      a Qualifying Bank by virtue of satisfying part (b) of the definition
      thereof shall nevertheless not be treated as a Qualifying Bank until the
      Obligors receive an appropriate direction as described in that part (b).

12.   MARKET DISRUPTION

12.1  Market disturbance

      (a)   If LIBOR is to be determined in accordance with paragraph (b) of its
            definition and a Reference Bank does not supply an offered rate by
            l1.30 a.m. on the applicable Rate Fixing Day, the applicable LIBOR
            shall, subject to paragraph (b) below, be determined on the basis of
            the quotations of the remaining Reference Banks.

      (b)   If, in relation to any proposed Loan:

            (i)   LIBOR is to be determined in accordance with paragraph (b) of
                  its definition and no, or only one, Reference Bank supplies a
                  rate by 11.30 a.m. on the applicable Rate Fixing Day for the
                  purposes of determining the applicable LIBOR; or

            (ii)  the Agent otherwise determines (which determination shall be
                  conclusive and binding on all parties) that adequate and fair
                  means do not exist for ascertaining the applicable LIBOR,

      the Agent shall promptly notify the Company and the relevant Banks of the
      fact and that this Clause 12 is in operation.

12.2  Alternative rates

      If the Agent gives a notice under Clause 12.1 (Market disturbance):

      (a)   the Company and the Banks may (through the Agent) agree that in the
            case of a Loan which has not been borrowed, that Loan shall not be
            borrowed; or

      (b)   in the absence of agreement, a Loan (if it has not been borrowed)
            shall still be made: and

            (i)   the Term or the Interest Period (as appropriate) of the Loans
                  concerned shall be one month; and

            (ii)  during the Term or the Interest Period (as appropriate) of
                  each Loan the rate of interest applicable to that Loan shall
                  be the applicable Margin plus the Mandatory Cost plus the rate
                  per annum which is expressed as a percentage rate per annum of
                  the cost to the Bank concerned of funding that Loan from
                  whatever sources it may reason ably select, which rate shall
                  be notified by the Bank concerned to the Agent before that
                  last date of such Term or the Interest Period (as
                  appropriate).

13.   INCREASED COSTS

13.1  Increased costs

      (a)   Subject to Clause 13.2 (Exceptions), the Company shall forthwith on
            demand by a Finance Party pay that Finance Party the amount of any
            increased cost incurred by it as a result of any law or regulation
            (including any relating to taxation or reserve asset, special
            deposit, cash ratio, liquidity or capital adequacy requirements or
            any other form of banking or monetary control).

      (b)   In this Agreement "increased cost" means:

            (ii)  that portion of an additional cost incurred by a Finance Party
                  in making, funding or maintaining all or any advances
                  comprised in a class of advances formed by or including the
                  participations in the Loans made or to be made under this
                  Agreement as is attributable to it making, funding or
                  maintaining those participations; or

            (iii) a reduction in any amount payable to a Finance Party or the
                  effective return to a Finance Party under this Agreement or on
                  its capital; or

            (iv)  the amount of any payment made by a Finance Party, or the
                  amount of interest or other return foregone by a Finance
                  Party, calculated by reference to any amount received or
                  receivable by a Finance Party from any other Party under this
                  Agreement.

13.2  Exceptions

      Clause 13.1 (Increased costs) does not apply to any increased cost:

      (a)   compensated for by the payment of the Mandatory Cost;

      (b)   attributable to any tax or amounts in respect of tax which must be
            deducted from any amounts payable or paid by the Company or payable
            or paid by the Agent to a Finance Party under the Finance Documents;

      (c)   attributable to any change in the rate of tax on the overall net
            income, profits or gains of a Bank (or the overall net income,
            profits or gains of a division or branch of the Bank) imposed in the
            jurisdiction in which its principal office or Facility Office is
            situate;

      (d)   arising directly out of the implementation by the applicable
            authorities having jurisdiction over such Finance Party and/or its
            Facility Office of the matters set out in the statement of the Basle
            Committee on Banking Regulations and Supervisory Practices dated

      which is in terms or has effects reasonably foreseeable by such Finance
      Party as at the date of this Agreement.

14.   ILLEGALITY AND MITIGATION

14.1  Illegality

      If it is or becomes unlawful in any jurisdiction for a Bank to give effect
      to any of its obligations as contemplated by this Agreement or to fund or
      maintain its participation in any Loan, then:

(a)   the Bank may notify the Company through the Agent accordingly; and

(b)   (i)   the Company shall to the extent required and within the period
            allowed or, if no period is allowed, forthwith prepay that Bank's
            participation in all the Loans together with all other amounts
            payable by it to that Bank under this Agreement; and

      (ii)  the Bank's Commitment shall be cancelled.

14.2  Mitigation

      Notwithstanding the provisions of Clauses 11 (Taxes), 13 (Increased costs)
      and 14.1 (Illegality), if in relation to a Bank or (as the case may be)
      the Agent circumstances arise which would result in:

      (a)   any deduction, withholding or payment of the nature referred to in
            Clause 11 (Taxes); or

      (b)   any increased cost of the nature referred to in Clause 13 (Increased
            costs); or

      (c)   a notification pursuant to Clause 14.1 (Illegality),

      then without in any way limiting, reducing or otherwise qualifying the
      rights of that Bank or the Agent, that Bank shall upon becoming aware of
      the same notify the Agent thereof (whereupon the Agent shall notify the
      Company) and such Bank shall use reasonable endeavours to transfer its
      participation in the Facility and its rights hereunder and under the
      Finance Documents to another financial institution or Facility Office not
      affected by the circumstances having the results set out in (a), (b) or
      (c) above and shall otherwise take such reasonable steps as may be open to
      it to mitigate the effects of such circumstances provided that such Bank
      shall not be under any obligation to take any such action if, in its
      reasonable opinion, to do so might have a material adverse effect upon its
      business, operations or financial condition or might involve it in any
      unlawful activity or any activity that is contrary to any request,
      guidance or directive of any competent authority (whether or not having
      the force of law) or (unless indemnified to its satisfaction) might
      involve it in any expense or tax disadvantage.

15.   GUARANTEE

15.1  Guarantee

      Holdco (if it becomes an Obligor by executing and delivering a Guarantor
      Accession Agreement in accordance with Clause 26.4 (Accession)),
      irrevocably and unconditionally and notwithstanding the release of the
      Company or any other person under the terms of any composition or
      arrangement with any creditors of any member of the Group:

      (a)   as principal obligor guarantees to each Finance Party prompt
            performance by the Company of all its obligations under the Finance
            Documents;

      (b)   undertakes with each Finance Party that, whenever the Company does
            not pay any amount when due under or in connection with any Finance
            Document. Holdco shall forthwith on demand by the Agent pay that
            amount as if Holdco instead of the Company were expressed to be the
            principal obligor; and

      (c)   indemnifies each Finance Party on demand against any loss or
            liability suffered by such Finance Party if any obligation
            guaranteed by Holdco is or becomes unenforceable, invalid or
            illegal.

15.2  Continuing guarantee

      This guarantee is a continuing guarantee and will extend to the ultimate
      balance of all sums payable by the Company under the Finance Documents and
      shall not be discharged by any intermediate payment or discharge in whole
      or in part.

15.3  Reinstatement

      (a)   Where any discharge (whether in respect of the obligations of any
            Obligor or any security for those obligations or otherwise) is made
            in whole or in part or any arrangement is made on the faith of any
            payment, security or other disposition which is avoided or must be
            restored on insolvency, liquidation or otherwise without limitation,
            the liability of Holdco under this Clause 15 shall continue as if
            the discharge or arrangement had not occurred.

      (b)   Each Finance Party may concede or compromise any claim that any
            payment, security or other disposition is liable to avoidance or
            restoration.

15.4  Waiver of defences

      The obligations of Holdco under this Clause 15 will not be affected by an
      act, omission, matter or thing which, but for this provision, would
      reduce, release or prejudice any of its obligations under this Clause 15
      or prejudice or diminish those obligations in whole or in part, including
      (whether or not known to it or any Finance Party):

(a)   any time or waiver granted to, or composition with, the Company or other
      person;

(b)   the taking, variation, compromise, exchange, renewal or release of, or
      refusal or neglect to perfect, take up or enforce, any rights against, or
      security over assets of, the Company or other person or any
      non-presentation or non-observance of any formality or other requirement
      in respect of any instrument or any failure to realise the full value of
      any security;

      (c)   any incapacity or lack of powers, authority or legal personality of
            or dissolution or change in the members of status of the Company or
            any other person;

      (d)   any variation (however fundamental) or replacement of a Finance
            Document or any other document or security so that references to
            that Finance Document in this Clause 15 shall include each variation
            or replacement;

      (e)   any unenforceability, illegality or invalidity of any obligation of
            any person under any Finance Document or any other document or
            security, to the intent that Holdco's obligations under this Clause
            15 shall remain in full force and its guarantee be construed
            accordingly, as if there were no unenforceability, illegality or
            invalidity;

      (f)   any postponement, discharge, reduction, non-provability or other
            similar circumstance affecting any obligation of Holdco under a
            Finance Document resulting from any insolvency, liquidation or
            dissolution proceedings or from the law, regulation or order so that
            each such obligation shall for the purposes of Holdco's obligations
            under this Clause 15 be construed as if there were no such
            circumstances; or

      (g)   the release of the Company or any other person under the terms of
            any composition or arrangement with any creditor of any member of
            the Group.

15.5  Immediate recourse

            Holdco waives any right it may have of first requiring any Finance
            Party (or any trustee or agent on its behalf) to proceed against or
            enforce any other rights or security or claim payment from any
            person before claiming from Holdco under this Clause 15.

15.6  Appropriations

            If a notice has been served on the Company under Clause 18.19

            Documents have been irrevocably paid in full, each Finance Party (or
            any trustee or agent on its behalf) may:

      (a)   refrain from applying or enforcing any other moneys, security or
            rights held or received by that Finance Party (or any trustee or
            agent on its behalf) in respect of those amounts, or apply and
            enforce the same in such manner and order as it sees fit (whether
            against those amounts or otherwise), and Holdco shall not be
            entitled to the benefit of the same; and

      (b)   hold in a suspense account any moneys received from Holdco or on
            account of the Holdco's liability under this Clause 15 which shall
            bear interest at an appropriate commercial rate as reasonably
            determined by such Finance Party.

15.7  Non-competition

      Until all amounts which may be or become payable by the Obligors under or
      in connection with the Finance Documents have been irrevocably paid in
      full, Holdco shall not, after a claim has been made or by virtue of any
      payment or performance by it under this Clause 15:

            receivable by any Finance Party (or any trustee or agent on its
            behalf) or be entitled to any right of contribution or indemnity in
            respect of any payment made or moneys received on account of
            Holdco's liability under this Clause 15;

      (b)   claim, rank, prove or vote as a creditor of the Company or its

      (c)   receive, claim or have the benefit of any payment, distribution or
            security from or on account of the Company, or exercise any right of

      delegated to it under or in connection with the Finance Documents,
      together with any other incidental rights, powers and discretions. The

      obligations of any kind to any other Party under or in connection with any
      Finance Document.

19.3  Relationship

      The relationship between the Agent and the other Finance Parties is that
      of agent and principal only. Nothing in this Agreement constitutes the
      Agent as trustee or fiduciary for any other Party or any other person and
      the Agent need not hold in trust any moneys paid to it for a Party or be
      liable to account for interest on those moneys.

19.4  Majority Banks' directions

      The Agent will be fully protected if it acts in accordance with the
      instructions of the Majority Banks in connection with the exercise of any
      right, power or discretion or any matter not expressly provided for in the
      Finance Documents. Any such instructions given by the Majority Banks will
      be binding on all the Banks. In the absence of such instructions the Agent
      may act as it considers to be in the best interests of all the Banks.

19.5  Delegation

      The Agent may act under the Finance Documents through its personnel and
      agents.

19.6  Responsibility for documentation

      Neither the Agent nor the Arranger is responsible to any other Party for:

      (a)   the execution, genuineness, validity, enforceability or sufficiency
            of any Finance Document or any other document;

      (b)   the collectability of amounts payable under any Finance Document; or

      (c)   the accuracy of any statements (whether written or oral) made in or
            in connection with any Finance Document.

19.7  Default

      (a)   The Agent is not obliged to monitor or enquire as to whether or not
            a Default has occurred. The Agent will not be deemed to have
            knowledge of the occurrence of a Default. However, if the Agent
            receives notice from a Party referring to this Agreement, describing
            the Default and stating that the event is a Default, it shall
            promptly notify the Banks.

      (b)   The Agent may require the receipt of security satisfactory to it
            whether by way of payment in advance or otherwise, against any
            liability or loss which it will or may incur in taking any
            proceedings or action arising out of or in connection with any
            Finance Document before it commences these proceedings or takes that
            action.

(a)   Without limiting paragraph (b) below, the Agent will not be liable to any
      other Party for any action taken or not taken by it under or in connection
      with any Finance Document, unless directly caused by its gross negligence
      or wilful misconduct.

(b)   No Party may take any proceedings against any officer, employee or agent
      of the Agent in respect of any claim it might have against the Agent or in
      respect of any act or omission of any kind (including negligence or wilful
      misconduct) by that officer, employee or agent in relation to any Finance
      Document.

19.9  Reliance

      The Agent may:

      (a)   rely on any notice or document believed by it to be genuine and
            correct and to have been signed by, or with the authority of, the
            proper person;

      (b)   rely on any statement made by a director or employee of any person
            regarding any matters which may reasonably be assumed to be within
            his knowledge or within his power to verify; and

      (c)   engage, pay for and rely on legal or other professional advisers
            selected by it (including those in the Agent's employment and those
            representing a Party other than the Agent).

19.10 Credit approval and appraisal

      Without affecting the responsibility of each Obligor for information
      supplied by it or on their behalf in connection with any Finance Document,
      each Bank confirms that it:

      (a)   has made its own independent investigation and assessment of the
            financial condition and affairs of the Obligors and their related
            entities in connection with its participation in this Agreement and
            has not relied exclusively on any information provided to it by the
            Agent or the Arranger in connection with any Finance Document; and

      (b)   will continue to make its own independent appraisal of the
            creditworthiness of the Obligors and their related entities while
            any amount is or may be outstanding under the Finance Documents or
            any Commitment is in force.

19.11 Information

(a)   The Agent shall promptly forward to the person concerned the original or a
      copy of any document which is delivered to the Agent by a Party for that
      person.

(b)   The Agent shall promptly supply a Bank with a copy of each document
      received by the Agent under Clause 4 (Conditions precedent) upon the
      request and at the expense of that Bank.

(c)   Except where this Agreement specifically provides otherwise, the Agent is
      not obliged to review or check the accuracy or completeness of any
      document it forwards to another Party.

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


(d)   Except as provided above, the Agent has no duty:

      (i)   either initially or on a continuing basis to provide any Bank with
            any credit or other information concerning the financial condition
            or affairs of any Obligor or any related entity of any Obligor
            whether coming into its possession or that of any of its related
            entities before, on or after the date of this Agreement; or

      (ii)  unless specifically requested to do so by a Bank in accordance with
            this Agreement, to request any certificates or other documents from
            any Obligor.

19.12 The Agent and the Arranger individually

(a)   If it is also a Bank, each of the Agent and the Arranger has the same
      rights and powers under this Agreement as any other Bank and may exercise
      those rights and powers as though it were not the Agent or the Arranger.

(b)   Each of the Agent and the Arranger may:

      (i)   carry on any business with any Obligor or its related entities;

      (ii)  act as agent or trustee for, or in relation to any financing
            involving, any Obligor or its related entities; and

      (iii) retain any profits or remuneration in connection with its activities
            under this Agreement or in relation to any of the foregoing.

19.13 Indemnities

(a)   Without limiting the liability of any Obligor under the Finance Documents,
      each Bank shall forthwith on demand indemnify the Agent for its proportion
      of any liability or loss incurred by the Agent in any way relating to or
      arising out of its acting as the Agent, except to the extent that the
      liability or loss arises directly from the Agent's gross negligence or
      wilful misconduct.

(b)   A Bank's proportion of the liability or loss set out in paragraph (a)
      above is the proportion which the Original Sterling Amount of its
      participation in the Loans (if any) bear to the Original Sterling Amount
      of all the Loans on the date of the demand. If, however, there are no
      Loans outstanding on the date of demand, then the proportion will be the
      proportion which its Commitment bears to the Total Commitments at the date
      of demand or, if the Total Commitments have been cancelled, bore to the
      Total Commitments immediately before being cancelled.

19.14 Compliance

(a)   The Agent may refrain from doing anything which might, in its opinion,
      constitute a breach of any law or regulation or be otherwise actionable at
      the suit of any person, and may do anything which, in its opinion, is
      necessary or desirable to comply with any law or regulation of any
      jurisdiction.

(b)   Without limiting paragraph (a) above, the Agent need not disclose any
      information relating to any Obligor or any of its related entities if the
      disclosure might, in the opinion of the Agent,

- --------------------------------------------------------------------------------
<PAGE>

                                       49

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


      constitute a breach of any law or regulation or any duty of secrecy or
      confidentiality or be otherwise actionable at the suit of any person.

19.15 Resignation of Agent

(a)   Notwithstanding its irrevocable appointment, the Agent may resign by
      giving notice to the Banks and the Company, in which case the Agent may
      forthwith appoint one of its Affiliates as successor Agent or, failing
      that, the Majority Banks may appoint a successor Agent.

(b)   If the appointment of a successor Agent is to be made by the Majority
      Banks but they have not, within 30 days after notice of resignation,
      appointed a successor Agent which accepts the appointment, the retiring
      Agent may appoint a successor Agent.

(c)   The resignation of the retiring Agent and the appointment of any successor
      Agent will both become effective only upon the successor Agent notifying
      all the Parties that it accepts the appointment. On giving the
      notification, the successor Agent will succeed to the position of the
      retiring Agent and the term "Agent" will mean the successor Agent.

(d)   The retiring Agent shall, at its own cost, make available to the successor
      Agent such documents and records and provide such assistance as the
      successor Agent may reasonably request for the purposes of performing its
      functions as the Agent under this Agreement.

(e)   Upon its resignation becoming effective, this Clause 19 shall continue to
      benefit the retiring Agent in respect of any action taken or not taken by
      it under or in connection with the Finance Documents while it was the
      Agent, and, subject to paragraph (d) above, it shall have no further
      obligation under any Finance Document.

19.16 Banks

      The Agent may treat each Bank as a Bank, entitled to payments under this
      Agreement and as acting through its Facility Office(s) until it has
      received notice from the Bank to the contrary by not less than five
      Business Days prior to the relevant payment.

19.17 Extraordinary management time and resources

      In addition to the fees (if any) paid or payable to the Agent pursuant to
      Clause 20 (Fees), an Obligor shall, on demand by the Agent, reimburse it
      for its own account at such reasonable daily or hourly rates as the Agent
      may separately agree with that Obligor from time to time, the reasonable
      cost of utilising its management time or other resources in connection
      with taking all such steps or other action which:

      (a)   that Obligor requests, in connection with:

            (i)   the granting or proposed granting of any waiver or consent
                  under any Finance Document; or

            (ii)  any amendment or proposed amendment to any Finance Document;
                  or

      (b)   which any Obligor or the Majority Banks request(s) in connection
            with:

            (i)   any breach by any Obligor of its obligations under any Finance
                  Document or any investigations in respect of any such breach;
                  or

            (ii)  the preservation and enforcement of any of the rights of the
                  Finance Parties under the Finance Documents; or

            (iii) the occurrence of a Default.

20.   FEES

      added tax or any other tax which might be chargeable in connection with

      be paid by the Company at the same time as it pays the relevant fee.

      under the Finance Documents or if that liability is converted into a
      claim, proof, judgment or order in a currency other than the currency (the
      "contractual currency") in which the amount is expressed to be payable
      under the relevant Finance Document:

      (i)   that Obligor shall indemnify that Finance Party as an independent

- --------------------------------------------------------------------------------
<PAGE>

                                       52

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


      (ii)  if the amount received by that Finance Party, when converted into
            the contractual currency at a market rate in the usual course of its
            business, is less than the amount owed in the contractual currency,
            the Obligor concerned shall forthwith on demand pay to that Finance
            Party an amount in the contractual currency equal to the deficit;
            and

      (iii) the Obligor shall pay to the Finance Party concerned on demand any
            exchange costs and taxes payable in connection with any such
            conversion.

      (d)   (other than by reason of negligence or default by a Finance Party) a

      to fund any amount payable under any Finance Document, any amount repaid
      or prepaid or any Loan.

24.   EVIDENCE AND CALCULATIONS

24.1  Accounts

      Accounts maintained by a Finance Party in connection with this Agreement
      are prima facie evidence of the matters to which they relate.

24.2  Certificates and determinations

      Any certification or determination by a Finance Party of a rate or amount
      under this Agreement is, in the absence of manifest error, conclusive
      evidence of the matters to which it relates.

24.3  Calculations

      Interest (including any applicable Mandatory Cost) and the fee payable
      under Clause 20.2 (Commitment fee) accrue from day to day and are

                                       53

      practice otherwise dictates, 360 days.

25.   AMENDMENTS AND WAIVERS

25.1  Procedure

(a)   Subject to Clause 25.2 (Exceptions), any term of the Finance Documents may
      be amended or waived with the agreement of the Company (on behalf of each
      Obligor), the Majority Banks and the Agent. The Agent may effect, on
      behalf of the Banks, an amendment to which they or the Majority Banks have
      agreed.

(b)   The Agent shall promptly notify the other Parties of any amendment or
      waiver effected under paragraph (a) above, and any such amendment or
      waiver shall be binding on all the Parties.

25.2  Exceptions

      An amendment or waiver which relates to:

      (a)   the definition of "Majority Banks" in Clause 1.1;

      (b)   an extension of the date for, or a decrease in an amount or a change
            in the currency of, any payment under the Finance Documents;

      (c)   an increase in a Bank's Commitment;

      (d)   the incorporation of additional borrowers;

      (e)   a term of a Finance Document which expressly requires the consent of
            each Bank; or

25.3  Waivers and remedies cumulative

      The rights of each Finance Party under the Finance Documents:

      (a)   may be exercised as often as necessary;

      (b)   are cumulative and not exclusive of its rights under the general
            law; and

      (c)   may be waived only in writing and specifically.

      Delay in exercising or non-exercise of any such right is not a waiver of
      that right.

26.   CHANGES TO THE PARTIES

26.1  Transfers by Obligors

      No Obligor may assign, transfer, novate or dispose of any of, or any
      interest in, its rights and/or obligations under this Agreement.

- --------------------------------------------------------------------------------
<PAGE>

                                       54

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


26.2  Transfers by Banks

(a)   A Bank (the "Existing Bank") may at any time assign, transfer or novate
      any of its rights and/or obligations under this Agreement (in a minimum
      amount equal to (pound)10,000,000 or, if less with respect to a particular
      Bank, the balance of that Bank's Commitment at the time of transfer) to
      another bank or financial institution which is a Qualifying Bank (the "New
      Bank"). The prior consent of the Company is required for any such
      assignment, transfer or novation, unless:

      (i)   the New Bank is another Bank or an Affiliate of a Bank; or

      (ii)  a Default is outstanding.

      However, the prior consent of the Company must not be unreasonably
      withheld or delayed and will be deemed to have been given if, within 14
      days of receipt by the Company of an application for consent, it has not
      been expressly refused.

(b)   A transfer of obligations will be effective only if either:

      (i)   the obligations are novated in accordance with Clause 26.3
            (Procedure for novations); or

      (ii)  the New Bank confirms to the Agent and the Company that it is a
            Qualifying Bank and that it undertakes to be bound by the terms of
            this Agreement as a Bank in form and substance satisfactory to the
            Agent. On the transfer becoming effective in this manner the
            Existing Bank shall be relieved of its obligations under this
            Agreement to the extent that they are transferred to the New Bank.

(c)   Nothing in this Agreement restricts the ability of a Bank to sub-contract
      an obligation if that Bank remains liable under this Agreement for that
      obligation except that no Bank may subcontract any such obligation if the
      effect of such contract would be that a person other than a Qualifying
      Bank has any beneficial entitlement to any interest received by it under
      this Agreement.

(d)   On each occasion that an Existing Bank assigns, transfers or novates any
      of its rights and/or obligations under this Agreement, the New Bank shall,
      on the date the assignment, transfer and/or novation takes effect, pay to
      the Agent for its own account a fee of (pound)750.

(e)   An Existing Bank is not responsible to a New Bank for:

      (i)   the execution, genuineness, validity, enforceability or sufficiency
            of any Finance Document or any other document;

      (ii)  the collectability of amounts payable under any Finance Document; or

      (iii) the accuracy of any statements (whether written or oral) made in or
            in connection with any Finance Document.

(f)   Each New Bank confirms to the Existing Bank and the other Finance Parties
      that it:

- --------------------------------------------------------------------------------
<PAGE>

                                       55

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


      (i)   has made its own independent investigation and assessment of the
            financial condition and affairs of each Obligor and its related
            entities in connection with its participation in this Agreement and
            has not relied exclusively on any information provided to it by the
            Existing Bank in connection with any Finance Document; and

      (ii)  will continue to make its own independent appraisal of the
            creditworthiness of each Obligor and its related entities while any
            amount is or may be outstanding under this Agreement or any
            Commitment is in force.

(g)   Nothing in any Finance Document obliges an Existing Bank to:

      (i)   accept a re-transfer from a New Bank of any of the rights and/or
            obligations assigned, transferred or novated under this Clause; or

      (ii)  support any losses incurred by the New Bank by reason of the
            non-performance by the Company of its obligations under this
            Agreement or otherwise.

(h)   Any reference in this Agreement to a Bank includes a New Bank, but
      excludes a Bank if no amount is or may be owed to or by that Bank under
      this Agreement and its Commitment has been cancelled or reduced to nil.

26.3  Procedure for novations

(a)   A novation is effected if the Existing Bank and the New Bank deliver to
      the Agent a Novation Certificate in the form of Schedule 5 and the Agent
      executes it.

(b)   Each Party (other than the Existing Bank and the New Bank) irrevocably
      authorises the Agent to execute any duly completed Novation Certificate in
      the form of Schedule 5 on its behalf.

(c)   To the extent that they are expressed to be the subject of the novation in
      the Novation Certificate:

      (i)   the Existing Bank and the other Parties (the "existing Parties")
            will be released from their obligations to each other (the
            "discharged obligations");

      (ii)  the New Bank and the existing Parties will assume obligations
            towards each other which differ from the discharged obligations only
            insofar as they are owed to or assumed by the New Bank instead of
            the Existing Bank;

      (iii) the rights of the Existing Bank against the existing Parties and
            vice versa (the "discharged rights") will be cancelled; and

      (iv)  the New Bank and the existing Parties will acquire rights against
            each other which differ from the discharged rights only insofar as
            they are exercisable by or against the New Bank instead of the
            Existing Bank,

      all on the date of execution of the Novation Certificate by the Agent or,
      if later, the date specified in the Novation Certificate.

26.4  Accession

(a)   Prior to the date that Holdco guarantees any obligations of any of its
      Subsidiaries in the Ring Fenced Group, the Company shall procure that
      Holdco delivers to the Agent a Guarantor Accession Agreement, duly
      executed by it.

(b)   Upon execution and delivery of a Guarantor Accession Agreement and all
      those other documents listed in Part 2 of Schedule 2, in each case in form
      and substance satisfactory to the Agent (acting reasonably), Holdco agrees
      to be bound by the terms of the Finance Documents.

26.5  Reference Banks

      If a Reference Bank (or, if a Reference Bank is not a Bank, the Bank of
      which it is an Affiliate) ceases to be one of the Banks, the Agent shall
      (in consultation with the Company) appoint another Bank or an Affiliate of
      a Bank to replace that Reference Bank.

26.6  Register

      The Agent shall keep a register of all the Parties and shall supply any
      other Party (at that Party's expense) with a copy of the register on
      request.

26.7  Change of Facility Office

      No Bank will change its Facility Office if, at the time of the change,
      circumstances exist which would oblige the Company to pay that Bank any
      amount under Clause 11.1 (Taxes) or Clause 13 (Increased costs) which it
      would not have been obliged to pay if that Bank had retained the same
      Facility Office.

27.   DISCLOSURE OF INFORMATION

(a)   A Bank may disclose to one of its Affiliates or any person with whom it is
      proposing to enter, or has entered into, any kind of transfer,
      participation or other agreement in relation to this Agreement:

      (i)   a copy of any Finance Document; and

      (ii)  any information which that Bank has acquired under or in connection
            with any Finance Document.

      Provided that any such Affiliate or person has agreed in writing to
      maintain the confidentiality of any such document or information on the
      same terms (with appropriate consequential changes) as set out in
      paragraph (c) below.

(b)   The prior written consent of the Company is required for any disclosure
      under paragraph (a) above unless:

      (i)   that person is another Bank or an Affiliate of a Bank; or

      (ii)  a Default is outstanding.

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

                                       57

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


      However, the prior consent of the Company must not be unreasonably
      withheld or delayed and will be deemed to have been given if, within 10
      Business Days of receipt by an Obligor of an application for consent, it
      has not been expressly refused.

(c)   Subject to paragraph (a) above, each Bank shall keep confidential and not,
      without the prior written consent of the Company, use any information
      (other than information which is publicly available unless as a result of
      a breach of this Clause 27) supplied by or on behalf of an Obligor under
      this Agreement otherwise than in connection with this Agreement. However,
      each Bank is entitled to disclose any information:

      (i)   in connection with any legal proceedings arising out of or in
            connection with this Agreement; or

      (ii)  if required to do so by an order of a court of competent
            jurisdiction whether in pursuance of any procedure for discovering
            documents or otherwise; or

      (iii) pursuant to any law or regulation in accordance with which that Bank
            is required to act; or

      (iv)  to any governmental, banking or taxation authority of competent
            jurisdiction; or

      (v)   to its auditors or legal or other professional advisers.

28.   SET-OFF

      A Finance Party may set off any matured obligation owed by an Obligor
      under this Agreement (to the extent beneficially owned by that Finance
      Party) against any obligation (whether or not matured) owed by that
      Finance Party to that Obligor, regardless of the place of payment, booking
      branch or currency of either obligation. If the obligations are in
      different currencies, the Finance Party may convert either obligation at a
      market rate of exchange in its usual course of business for the purpose of
      the set-off. If either obligation is unliquidated or unascertained, the
      Finance Party may set off in an amount estimated by it in good faith to be
      the amount of that obligation.

29.   PRO RATA SHARING

29.1  Redistribution

      If any amount owing by an Obligor under this Agreement to a Finance Party
      (the "recovering Finance Party") is discharged by payment, set-off or any
      other manner other than through the Agent in accordance with Clause 10
      (Payments) (a "recovery"), then:

      (a)   the recovering Finance Party shall, within three Business Days,
            notify details of the recovery to the Agent;

      (b)   the Agent shall determine whether the recovery is in excess of the
            amount which the recovering Finance Party would have received had
            the recovery been received by the Agent and distributed in
            accordance with Clause 10 (Payments);

- --------------------------------------------------------------------------------
<PAGE>

                                       58

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


      (c)   subject to Clause 29.3 (Exception), the recovering Finance Party
            shall, within three Business Days of demand by the Agent, pay to the
            Agent an amount (the "redistribution") equal to the excess;

      (d)   the Agent shall treat the redistribution as if it were a payment by
            that Obligor under Clause 10 (Payments) and shall pay the
            redistribution to the Finance Parties (other than the recovering
            Finance Party) in accordance with Clause 10.7 (Partial payments);
            and

      (e)   after payment of the full redistribution, the recovering Finance
            Party will be subrogated to the portion of the claims paid under
            paragraph (d) above, and that Obligor will owe the recovering
            Finance Party a debt which is equal to the redistribution,
            immediately payable and of the type originally discharged.

29.2  Reversal of redistribution

      If under Clause 29.1 (Redistribution):

      (a)   a recovering Finance Party must subsequently return a recovery, or
            an amount measured by reference to a recovery, to an Obligor; and

      (b)   the recovering Finance Party has paid a redistribution in relation
            to that recovery,

      each Finance Party shall, within three Business Days of demand by the
      recovering Finance Party through the Agent, reimburse the recovering
      Finance Party all or the appropriate portion of the redistribution paid to
      that Finance Party. Thereupon the subrogation in Clause 29.1(e)
      (Redistribution) will operate in reverse to the extent of the
      reimbursement.

29.3  Exception

      A recovering Finance Party need not pay a redistribution to the extent
      that it would not, after the payment, have a valid claim against the
      Obligor concerned in the amount of the redistribution pursuant to Clause
      29.1(e) (Redistribution).

30.   SEVERABILITY

      If a provision of any Finance Document is or becomes illegal, invalid or
      unenforceable in any jurisdiction, that shall not affect:

      (a)   the legality, validity or enforceability in that jurisdiction of any
            other provision of the Finance Documents; or

      (b)   the legality, validity or enforceability in other jurisdictions of
            that or any other provision of the Finance Documents.

31.   COUNTERPARTS

      This Agreement may be executed in any number of counterparts, and this has
      the same effect as if the signatures on the counterparts were on a single
      copy of this Agreement.

      proceeding, and to settle any disputes, which may arise out of or in
      connection with this Agreement and, for such purposes, irrevocably submits
      to the jurisdiction of such courts.

(b)   The Company irrevocably waives any objection which it might now or
      hereafter have to the courts referred to in paragraph (a) above being
      nominated as the forum to hear and determine any suit, action or
      proceeding, and to settle any disputes, which may arise out of or in

      is not a convenient or appropriate forum.

(c)   The submission to the jurisdiction of the courts referred to in paragraph
      (a) above shall not (and shall not be construed so as to) limit the right
      of the Agent or the Banks to take proceedings in any other court of
      competent jurisdiction nor shall the taking of proceedings in any one or
      more jurisdictions preclude the taking of proceedings in any other
      jurisdiction, whether concurrently or not.

This Agreement has been entered into on the date stated at the beginning of this
Agreement.

                                   SCHEDULE 3

                       CALCULATION OF THE MANDATORY COST

(a)   The Mandatory Cost for each Loan for each period in respect of which
      interest is payable is the rate determined by the Agent to be equal to the
      rate notified by the Agent and calculated in accordance with the following
      formulae:

      in relation to a Loan denominated in Sterling:

      BY + S(Y-Z) + F x 0.01 % per annum = Mandatory Cost
      ----------------------
           100-(B + S)

      in relation to any other Loan:

      F x 0.01 % per annum = Mandatory Cost
      --------
           300

      where on the day of application of the formula:

      B     is the percentage of the Agent's eligible liabilities which the Bank
            of England requires the Agent to hold on a non-interest-bearing
            deposit account in accordance with its cash ratio requirements;

      Y     is the rate at which Sterling deposits are offered by the Agent to
            leading banks in the London interbank market at or about 11.00 a.m.
            on that day for the Term or Interest Period;

      S     is the percentage of the Agent's eligible liabilities which the Bank
            of England requires the Agent to place as a special deposit;

      Z     is the interest rate per annum allowed by the Bank of England on
            special deposits; and

      F     is the charge payable by the Agent to the Financial Services
            Authority under paragraph 2.02 or 2.03 (as appropriate) of the Fees
            Regulations (but where for this purpose, the figure in paragraph
            2.02b and 2.03b will be deemed to be zero) expressed in pounds per
            (pound)1 million of the fee base of the Agent.

(b)   For the purposes of this Schedule 3:

      (i)   "eligible liabilities" and "special deposits" have the meanings
            given to them at the time of application of the formula by the Bank
            of England;

      (ii)  "fee base" has the meaning given to it in the Fees Regulations;

      (iii) "Fees Regulations" means:

            (A)   prior to 31st March, 1999, the Banking Supervision (Fees)
                  Regulations 1998; and

            (B)   on and after 31st March, 1999, any regulations governing the
                  payment of fees for banking supervision.

(c)   In the application of the formula, B, Y, S and Z are included in the
      formula as figures and not as percentages, e.g. if B = 0.5% and Y = 15%,
      BY is calculated as 0.5 x 15.

(d)   (i)   The formula is applied on the first day of each relevant period
            comprised in the relevant Term or Interest Period.

      (ii)  Each rate calculated in accordance with the formula is, if
            necessary, rounded upward to the nearest four decimal places.

(e)   If the Agent determines (after consultation with the Banks) that a change
      in circumstances has rendered, or will render, the formula inappropriate,
      the Agent shall notify the Company of the manner in which the Mandatory
      Cost will subsequently be calculated. The manner of calculation so
      notified by the Agent shall, in the absence of manifest error, be binding
      on all the parties to this Agreement.

                                   SCHEDULE 6

                     FORM OF LEGAL OPINION OF ALLEN & OVERY

To:   The Royal Bank of Scotland plc
      Waterhouse Square
      138-142 Holborn
      London EC1N 2TH
      (as Agent for the Finance Parties)

                                                          [              ], 1999

Dear Sirs,


                      Scottish Power plc (the "Company") -
                 (pound)600,000,000 Revolving Credit Agreement
              dated [              ], 1999 (the "Credit Agreement")

We have acted as legal advisers in England to The Royal Bank of Scotland plc
(the "Agent") in connection with a Credit Agreement dated [              ], 1999
(the "Credit Agreement") made between the Company as borrower, The Royal Bank of
Scotland plc as Arranger, the Banks (as defined therein) and the Agent.

Terms defined in the Credit Agreement have the same meanings when used in this
opinion.

We have received instructions from and participated in discussions with the
Agent about the provisions contained in the Credit Agreement.

We have examined the following documents:

(a)   an executed copy of the Credit Agreement; and

(b)   the legal opinion of Maclay Murray & Spens legal advisers to the Agent in
      Scotland dated [              ], 1999 and addressed to the Finance
      Parties.

Except as stated above we have not examined any contracts, instruments or other
documents entered into by or affecting the Company or any corporate records of
the Company and have not made any other enquiries concerning the Company.

In giving this opinion, we have assumed:

(i)   the genuineness of all signatures;

(ii)  the authenticity and completeness of all documents submitted to us as
      originals;

(iii) the conformity to original documents of all documents submitted to us as
      copies and the authenticity and completeness of such original documents;

- --------------------------------------------------------------------------------
<PAGE>

                                       72

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


(iv)  the power and authority to execute and the due execution of the Credit
      Agreement by the Company, each Bank, the Arranger and the Agent, and that
      the obligations expressed to be assumed by each Bank, the Arranger and the
      Agent under the Credit Agreement are legally valid;

(v)   that, so far as the laws of Scotland are concerned, the Credit Agreement
      constitutes a valid and legally binding obligation of the Company in
      accordance with its terms; and

(vi)  that the certificates and other documents dated earlier than the date
      hereof and on which we have expressed reliance remain accurate and that
      there have been no variations to any such certificates or documents.

We have not investigated the laws of any country other than England and this
opinion is given only with respect to English law. We assume that no foreign law
which may apply with respect to the Credit Agreement or the transactions and
matters contemplated thereby would be such as to affect any of the conclusions
stated herein. We express no opinion as to matters of fact.

Based upon and subject to the foregoing and subject to any matters not disclosed
to us we are of the opinion that, so far as the present laws of England are
concerned and subject to the qualifications set out below:

(A)   Legal validity  The Credit Agreement constitutes valid and legally binding
      obligations of the Company.

(B)   Stamp duties  No stamp or registration duty or similar taxes or charges
      are payable in the United Kingdom in respect of the execution or delivery
      of the Credit Agreement.

(C)   Registrations  It is not necessary to register the Credit Agreement in any
      public office or elsewhere in England.

Notwithstanding the foregoing this opinion is subject to the following
qualifications:

(i)   The validity, performance and enforcement of the Credit Agreement may be
      limited by bankruptcy, insolvency, reorganisation or similar laws
      affecting creditors' rights generally.

(ii)  Remedies such as specific performance or the issue of an injunction are
      available only at the discretion of the court. Specific performance is not
      usually granted and an injunction is not usually issued where damages
      would be an adequate alternative.

(iii) The Credit Agreement provides for interest to be paid on overdue amounts.
      Such interest may amount to a penalty under English law and may therefore
      not be recoverable.

(iv)  We express no opinion as to the enforceability of Clause 29 (Pro rata
      sharing) of the Credit Agreement.

(v)   An English court may stay proceedings if concurrent proceedings are being
      brought elsewhere.

(vi)  There could be circumstances in which an English court would not treat as
      conclusive those certificates and determinations which the Credit
      Agreement states are to be so treated.

<PAGE>

                                       73

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


(vii) The obligations contained in Clause 22 (Stamp duties) of the Agreement may
      be void in respect of stamp duty payable in the United Kingdom.

(viii) Clause 30 (Severability) of the Credit Agreement may not be effective in
       certain circumstances depending on the nature of the prohibition or
       unenforceability in question.

(ix)  The Credit Agreement may be amended orally by the parties thereto
      notwithstanding provisions therein to the contrary.

(x)   English courts may not give effect to any provision for reimbursement of
      legal costs incurred by an unsuccessful litigant.

(xi)  The effectiveness of terms exculpating a party from a liability or duty
      otherwise owed may be limited by law.

(xii) There is no authority as to whether or not an English court would give
      effect to the currency indemnity contained in Clause 23.1 (Currency
      indemnity) of the Credit Agreement. However, the English courts will now
      render judgments in foreign currencies.

(xiii) On the assumption that a Novation Certificate is duly completed,
       executed, authorised and delivered to the Agent in accordance with the
       Credit Agreement and any conditions to which the Novation Certificate is
       expressed to be subject are satisfied, then the provisions of Clause 26.3
       (Procedure for novations) will operate in accordance with its terms.
       However, without prejudice to the preceding sentence, no opinion is
       expressed with respect to any Novation Certificate issued after the date
       of this opinion because we do not know the identity of the parties
       concerned and this opinion is given only as at today's date. In any
       event, it should be noted that in certain circumstances transactions
       employing Novation Certificates and assignments or transfers of interests
       in the Credit Agreement may require compliance with the Financial
       Services Act 1986.

(xiv) A person may not be able to enforce a provision of the Credit Agreement
      expressed to be in his favour unless he is a party.

This opinion is given for the sole benefit of the Agent, the Arranger and the
Banks which are the original parties to the Credit Agreement and may not be
disclosed to, or relied upon by, any other person or be quoted or made public in
any way without our prior written consent.

Yours faithfully,

                 FORM OF LEGAL OPINION OF MACLAY MURRAY & SPENS

Ref:  RJL/SMK

[              ], 1999

The Royal Bank of Scotland plc
Waterhouse Square
138-142 Holborn
LONDON
EC1N 2TH
(as Agent for the Finance Parties)

Dear Sirs,

You have asked for our opinion in connection with an agreement of even date with
this opinion between Scottish Power plc as borrower (the "Company"), The Royal
Bank of Scotland plc as Arranger, the Banks (as defined therein) and The Royal
Bank of Scotland plc as agent (the "Agent") (the "Facility Agreement").

For the purposes of this opinion, we have examined copies of and base our
opinion on the following documents, copies of which we have signed and attach
for the purposes of identification (other than the Company Search):

(a)   an executed copy of the Facility Agreement;

(b)   a certified copy of the Memorandum and Articles of Association of the
      Company;

(c)   a microfiche of the files of the Company obtained from the Registrar of
      Companies in Edinburgh on [     , 1999] (the "Company Search");

(d)   a certified copy of the minutes of a meeting of the board of directors of
      the Company held on [    1999] (the "Directors' Minutes");

(e)   a certificate of a director of the Company confirming that the utilisation
      by the Company of the said Facility (as defined in the Facility Agreement)
      (the "Director Certificate") in full would not cause any internal
      borrowing limit binding on the Company to be exceeded; and

(f)   a certificate of an authorised signatory of the Company (the "Authorised
      Signatory Certificate") certifying that each of the items in paragraphs
      (b) and (d) is correct, complete and in full force. The Director
      Certificate and Authorised Signatory Certificate are herein together
      referred to as "the Certificates").

                                       75

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


We have not made any other enquiries concerning the Company and in particular we
have not concerned ourselves with investigating or verifying any matters of fact
or opinion (whether set out in any of the documents referred to above or
elsewhere) other than as expressly stated herein. We have not reviewed and
express no opinion on any government regulations, subordinate legislation or
statutes relating to the operation of the electricity, water or sewerage
industries in the United Kingdom.

We have assumed for the purposes of this opinion:

(i)   the capacity, power and authority of each of the Joint Arrangers, the
      Co-Arranger, the Banks and the Agent to enter into and perform their
      respective obligations under the Facility Agreement and the due execution
      and delivery of the Facility Agreement by each of the Arrangers, the Banks
      and the Agent;

(ii)  that the Facility Agreement has been signed by [              ] and
      [              ] on behalf of the Company and that the Facility Agreement
      has been duly delivered;

(iii) the conformity to original documents of all documents supplied to us as
      photocopies, specimen or facsimile copies;

(iv)  that each of the statements contained in the Certificates (on which we
      have relied without further inquiry) is true and correct as at the date
      hereof;

(v)   that the meeting of the board of directors of the Company held on
      [              ], 1999 was duly convened and held;

(vi)  that the information disclosed by the Company Search was accurate in all
      respects and that such Search did not fail to disclose any material
      information which had been delivered for registration but which did not
      appear on the microfiche supplied by the Companies Registry in Edinburgh;

(vii) the Company has not passed a voluntary winding-up resolution, no petition
      has been presented or order made by the Court for the winding up,
      dissolution or administration of the Company and no receiver, trustee,
      administrator or similar official has been appointed in relation to the
      Company or any of its assets or revenues; and

(viii) that the Facility Agreement constitutes a legal, valid and binding
       obligation of the parties thereto under English law to which it is
       expressed to be subject and that the performance of the obligations
       thereunder is not illegal or unenforceable by virtue of the law of any
       jurisdiction (other than Scotland) in which they are to be performed.

We have not made any investigation of and do not express any opinion as to the
laws of any jurisdiction outside Scotland and this opinion relates only to the
laws of Scotland as they exist at the date hereof.

Based upon and subject to the foregoing and subject to the reservations
hereinafter referred to and to any matters not disclosed to us, we are of the
opinion that:

1.    The Company is a limited liability company duly incorporated under the
      laws of Scotland and has full corporate power and authority to execute,
      deliver and perform its obligations under the Facility Agreement.

- --------------------------------------------------------------------------------
<PAGE>

                                       76

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


2.    The execution and delivery by the Company of the Facility Agreement and
      the performance of its obligations thereunder have been duly authorised by
      all requisite corporate action on its part.

3.    The obligations of the Company under the Facility Agreement are valid and
      binding obligations of the Company under the law of Scotland and would be
      so treated in the Courts of Scotland.

4.    The entry into and performance of the Facility Agreement by the Company
      and the transaction and matters to be implemented thereunder do not
      violate (i) Scottish Law or (ii) the Memorandum and Articles of
      Association of the Company.

5.    It is not necessary to file, register or record the Facility Agreement
      with any court or authority in Scotland.

6.    No stamp, registration or other similar taxes or charges are payable in
      Scotland with respect to the execution or delivery of the Facility
      Agreement.

7.    The choice of English law to govern the Facility Agreement is valid and
      effective under the private international law of Scotland. Subject to the
      usual exceptions affecting such matters as procedure, the availability of
      remedies and any provision which is repugnant to the law of Scotland, the
      law of England will accordingly be applied by the Courts of Scotland if
      any dispute arising from or contractual claim connected with the Facility
      Agreement comes under their jurisdiction. A judgment rendered against the
      Company by a competent court in England and registered in Scotland
      pursuant to the provisions of the Civil Jurisdiction and Judgments Act
      1982 will be enforceable by the Scottish Courts.

8.    The submission by the Company to the jurisdiction of the courts of England
      is valid and binding on the Company.

The foregoing opinion is subject to the following qualifications:

(a)   We do not express any view on the particular remedies available on
      enforcement, such as specific implement or interdict, which are
      discretionary remedies.

(b)   The enforcement of the Facility Agreement may be limited by applicable
      laws relating to prescription, limitation, bankruptcy, liquidation,
      receivership, administration, insolvency or other laws relating to
      creditors' rights generally or by the application of rules of equity or
      public policy.

(c)   A Scottish court may refuse to give effect to any provisions of the
      Facility Agreement providing for the payment of legal costs and other
      costs, charges and expenses in respect of the cost of unsuccessful
      litigation brought before such court or where that court has itself made
      an order for costs.

(d)   Any provision contained in the Facility Agreement to the effect that a
      calculation and/or certification will be conclusive and binding may not be
      effective if such calculation or certification is fraudulent or erroneous
      on its face and will not necessarily prevent judicial enquiry into the
      merit of any claim under the relative document.

                                       77

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


(e)   Any provision in the Facility Agreement relating to default interest would
      be unenforceable if it were held to constitute a penalty and not a genuine
      and reasonable pre-estimate of the damage likely to be suffered as a
      result of the default in payment of the amount in question.

(f)   We express no opinion whether any provision in the Facility Agreement
      conferring on any party thereto a right of set off or similar right would
      be effective against a liquidator or creditor.

(g)   We have not been asked to advise you in connection with the preparation of
      the Facility Agreement and we therefore express no opinion on the
      implications of the Facility Agreement or on whether the Facility
      Agreement gives effect to the commercial intentions of the parties.

(h)   Any undertakings or indemnities in relation to United Kingdom stamp duties
      given by the Company may be void under the provisions of Section 117 of
      the Stamp Act 1891.

(i)   A Scottish court may stay proceedings if concurrent proceedings are being
      brought elsewhere.

(j)   The effectiveness of terms exculpating a party from a liability or duty
      otherwise owed is limited by law.

This opinion shall be governed by and construed in accordance with the law of
Scotland.

This opinion is strictly limited to the matters specifically stated herein and
is not to be read as extending by implication to any other matter.

This opinion is provided solely for the benefit of the person to which it is
addressed and may not be communicated to or relied upon by any other person,
firm or corporation whatsoever.

Yours faithfully,

                                   SCHEDULE 2

                        CALCULATION OF THE MANDATORY COST

(a)   The Mandatory Cost for each Loan for each period in respect of which
      interest is payable is the rate determined by the Agent to be equal to the
      rate notified by the Agent and calculated in accordance with the following
      formulae:

      BY + S(Y-Z) + F x 0.01 % per annum = Mandatory Cost
      ----------------------
            100-(B + S)

      where on the day of application of the formula:

      B     is the percentage of the Agent's eligible liabilities which the Bank
            of England requires the Agent to hold on a non-interest-bearing
            deposit account in accordance with its cash ratio requirements;

      Y     is the rate at which Sterling deposits are offered by the Agent to
            leading banks in the London interbank market at or about 11.00 a.m.
            on that day for the relevant period;

      S     is the percentage of the Agent's eligible liabilities which the Bank
            of England requires the Agent to place as a special deposit;

      Z     is the interest rate per annum allowed by the Bank of England on
            special deposits; and

      F     is the charge payable by the Agent to the Financial Services
            Authority under paragraph 2.02 or 2.03 (as appropriate) of the Fees
            Regulations (but where for this purpose, the figure in paragraph
            2.02b and 2.03b will be deemed to be zero) expressed in pounds per
            (pound)1 million of the fee base of the Agent.

(b)   For the purposes of this Schedule 2:

      (i)   "eligible liabilities" and "special deposits" have the meanings
            given to them at the time of application of the formula by the Bank
            of England;

      (ii)  "fee base" has the meaning given to it in the Fees Regulations;

      (iii) "Fees Regulations" means:

            (A)   prior to 31st March, 1999, the Banking Supervision (Fees)
                  Regulations 1998; and

            (B)   on and after 31st March, 1999, any regulations governing the
                  payment of fees for banking supervision; and

      (iv)  "relevant period" in relation to each Term, means:

            (A)   if it is three months or less, that Term; or
<PAGE>

                                       15


            (B)   if it is more than three months, three months.

(c)   In the application of the formula, B, Y, S and Z are included in the
      formula as figures and not as percentages, e.g. if B=0.5% and Y=15%, BY is
      calculated as 0.5 x 15.

(d)   (i)   The formula is applied on the first day of each relevant period
            comprised in the relevant Term.

      (ii)  Each rate calculated in accordance with the formula is, if
            necessary, rounded upward to the nearest four decimal places.

(e)   If the Agent determines (after consultation with the Banks) that a change
      in circumstances has rendered, or will render, the formula inappropriate,
      the Agent shall notify the Company of the manner in which the Mandatory
      Cost will subsequently be calculated. The manner of calculation so
      notified by the Agent shall, in the absence of manifest error, be binding
      on all the parties to this Agreement.

THIS GUARANTEE is dated [                 ] between:

(1)   [HOLDCO] (Registered No. SC193794) ("Holdco"); and

(2)   THE ROYAL BANK OF SCOTLAND PLC as agent acting on behalf of the Finance
      Parties (the "Agent").

BACKGROUND

On and subject to the terms of a credit agreement dated 24th June, 1996, as
amended by a letter dated 29th January, 1998, between, amongst others, Scottish
Power plc (the "Company") and the Agent (the "Credit Agreement") (as amended by
a supplemental agreement dated 12th March, 1999 between the Company and the
Agent (the "Supplemental Agreement")) the Banks (as defined therein) agreed to
make the Facility available to the Company.

IT IS AGREED as follows:

1.    INTERPRETATION

(a)   Capitalised terms defined in the Credit Agreement have, unless expressly
      defined in this Guarantee, the same meaning in this Guarantee.

(b)   The provisions of clause 1.2 of the Credit Agreement apply to this
      Guarantee as though they were set out in full in this Guarantee except
      that references to the Credit Agreement are to be construed as references
      to this Guarantee.

2.    GUARANTEE

2.1   Guarantee

      In consideration of the Finance Parties, at any time making or continuing
      advances under the Credit Agreement or for other sufficient consideration
      (receipt of which Holdco acknowledges), Holdco irrevocably and
      unconditionally:

      (a)   as principal obligor guarantees to each Finance Party prompt
            performance by the Company of all its obligations under the Finance
            Documents;

      (b)   undertakes with each Finance Party that, whenever the Company does
            not pay any amount when due under or in connection with any Finance
            Document, Holdco shall forthwith on demand by the Agent pay that
            amount as if it instead of the Company were expressed to be the
            principal obligor; and

      (c)   indemnifies each Finance Party on demand against any loss or
            liability suffered by such Finance Party if any obligation of the
            Company guaranteed by Holdco is or becomes unenforceable, invalid or
            illegal.

2.2   Continuing guarantee

      This Guarantee is a continuing guarantee, will extend to the ultimate
      balance of all sums payable by the Company under the Finance Documents and
      shall not be discharged by any intermediate payment or discharge in whole
      or in part.
<PAGE>

                                       19


2.3   Reinstatement

(a)   Where any discharge (whether in respect of the obligations of the Company
      or any security for those obligations or otherwise) is made in whole or
      in part or any arrangement is made on the faith of any payment, security
      or other disposition which is avoided or must be restored on insolvency,
      liquidation or otherwise without limitation, the liability of Holdco under
      this Guarantee shall continue as if the discharge or arrangement had not
      occurred.

(b)   Each Finance Party may concede or compromise any claim that any payment,
      security or other disposition is liable to avoidance or restoration.

2.4   Waiver of defences

      The obligations of Holdco under this Guarantee will not be affected by any
      act, omission, matter or thing which, but for this provision, would
      reduce, release or prejudice any of its obligations under this Guarantee
      or prejudice or diminish those obligations in whole or in part, including
      (whether or not known to it or any Finance Party):

      (a)   any time or waiver granted to, or composition with, the Company or
            other person;

      (b)   the taking, variation, compromise, exchange, renewal or release of,
            or refusal or neglect to perfect, take up or enforce, any rights
            against, or security over assets of, the Company or other person or
            any non-presentation or non-observance of any formality or other
            requirement in respect of any instrument or any failure to realise
            the full value of any security;

      (c)   any incapacity or lack of powers, authority or legal personality of
            or dissolution or change in the members or status of the Company or
            any other person;

      (d)   any variation (however fundamental) or replacement of a Finance
            Document or any other document or security so that references to
            that Finance Document in this Guarantee shall include each variation
            or replacement;

      (e)   any unenforceability, illegality or invalidity of any obligation of
            any person under any Finance Document or any other document or
            security, to the intent that the obligations of Holdco under this
            Guarantee shall remain in full force and its guarantee be construed
            accordingly, as if there were no unenforceability, illegality or
            invalidity;

      (f)   any postponement, discharge, reduction, non-provability or other
            similar circumstance affecting any obligation of any Obligor under a
            Finance Document resulting from any insolvency, liquidation or
            dissolution proceedings or from any law, regulation or order so that
            each such obligation shall for the purposes of the obligations of
            Holdco under this Guarantee be construed as if there were no such
            circumstance; or

      (g)   the release of the Company or any other person under the terms of
            any composition or arrangement with any creditor of any member of
            the Group.

                                       20


2.5   Immediate recourse

      Holdco waives any right it may have of first requiring any Finance Party
      (or any trustee or agent on its behalf) to proceed against or enforce any
      other rights or security or claim payment from any person before claiming
      from it under this Guarantee.

2.6   Appropriations

      Until all amounts which may be or become payable by the Obligors under or
      in connection with the Finance Documents have been irrevocably paid in
      full, each Finance Party (or any trustee or agent on its behalf) may:

      (a)   refrain from applying or enforcing any other moneys, security or
            rights held or received by that Finance Party (or any trustee or
            agent on its behalf) in respect of those amounts, or apply and
            enforce the same in such manner and order as it sees fit (whether
            against those amounts or otherwise) and Holdco shall not be entitled
            to the benefit of the same; and

      (b)   hold in a suspense account bearing interest at a commercial rate any
            moneys received from Holdco or on account of the liability of Holdco
            under this Guarantee.

2.7   Non-competition

      Until all amounts which may be or become payable by the Obligors under or
      in connection with the Finance Documents have been irrevocably paid in
      full, Holdco shall not, after a claim has been made or by virtue of any
      payment or performance by it under this Guarantee:

      (a)   be subrogated to any rights, security or moneys held, received or
            receivable by any Finance Party (or any trustee or agent on its
            behalf) or be entitled to any right of contribution or indemnity in
            respect of any payment made or moneys received on account of
            Holdco's liability under this Guarantee;

      (b)   claim, rank, prove or vote as a creditor of the Company or its
            estate in competition with any Finance Party (or any trustee or
            agent on its behalf) unless otherwise required by law; or

      (c)   receive, claim or have the benefit of any payment, distribution or
            security from or on account of the Company, or exercise any right of
            set-off as against the Company.

      Holdco shall hold in trust for and forthwith pay or transfer to the Agent
      for the Finance Parties any payment or distribution or benefit of
      security received by it contrary to this Clause 2.7 (Non-competition) or
      if required by law as contemplated by paragraph (b) above or as directed
      by the Agent.

2.8   Additional security

      This Guarantee is in addition to and is not in any way prejudiced by any
      other security now or subsequently held by any Finance Party.

                                       21


3.    DEFAULT INTEREST

(a)   If Holdco fails to pay any amount payable by it under this Guarantee, it
      shall forthwith on demand by the Agent pay interest on the overdue amount
      from the due date up to the date of actual payment, as well as before
      judgment, at a rate (the "default rate") determined by the Agent to be one
      per cent. per annum above the higher of:

      (i)   the rate payable on the overdue amount under clause 8.1 (Interest
            rate) of the Credit Agreement immediately before the due date (if of
            principal); and

      (ii)  the rate which would have been payable if the overdue amount had,
            during the period of non-payment, constituted a Loan in Sterling for
            such successive Terms of such duration as the Agent may determine
            (each a "Designated Term").

(b)   The default rate will be determined by the Agent on each Business Day or
      the first day of the relevant Designated Term, as appropriate.

(c)   If the Agent determines that deposits in Sterling are not at the relevant
      time being made available by the Reference Banks to leading banks in the
      London interbank market, the default rate will be determined by reference
      to the cost of funds to the Agent from whatever sources it reasonably
      selects, after consultation with the Reference Banks.

(d)   Default interest will be compounded monthly (where paragraph (a)(i)
      applies) and at the end of each Designated Term (in each other case).

(e)   The Agent shall promptly notify Holdco of the determination of a rate of
      interest under this Guarantee.

4.    PAYMENTS

4.1   Place

      All payments by Holdco under this Guarantee shall be made to the Agent at
      its account at such office or bank as it may notify to Holdco for this
      purpose.

4.2   Funds

      Payments under this Guarantee to the Agent shall be made in Sterling for
      value on the due date.

4.3   Currency

      All amounts payable under this Guarantee are payable in Sterling.

4.4   Set-off and counterclaim

      All payments made by Holdco under this Guarantee shall be made without
      set-off or counterclaim.
<PAGE>

                                       22


4.5   Non-Business Days

(a)   If a payment under this Guarantee is due on a day which is not a Business
      Day, the due date for that payment shall instead be the next Business Day
      in the same calendar month (if there is one) or the preceding Business Day
      (if there is not).

(b)   During any extension of the due date for payment of any principal under
      this Guarantee interest is payable on that principal at the rate payable
      on the original due date.

4.6   Partial payments

      If the Agent receives a payment insufficient to discharge all the amounts
      then due and payable by Holdco under this Guarantee, the Agent shall apply
      that payment towards the obligations of Holdco under this Guarantee in
      such order as the Agent, in its absolute discretion, considers
      appropriate, and that application shall override any application made by
      Holdco.

5.    TAXES

5.1   Gross-up

      All payments by Holdco under this Guarantee shall be made free and clear
      of and without deduction for or on account of any taxes levied or imposed
      by or on behalf of the United Kingdom or any taxing authority thereof,
      except to the extent that Holdco is required by law to make payment
      subject to any taxes. If any tax or amounts in respect of tax must be
      deducted, or any other deductions must be made, from any amounts payable
      or paid by Holdco, or paid or payable by the Agent to a Bank under the
      Finance Documents, Holdco shall pay such additional amounts as may be
      necessary to ensure that the relevant Bank receives a net amount equal to
      the full amount which it would have received had payment not been made
      subject to tax.

5.2   Tax receipts

      All taxes required by law to be deducted or withheld by Holdco from any
      amounts paid or payable under this Guarantee shall be paid by Holdco when
      due and Holdco shall, within 30 days of the payment being made, deliver to
      the Agent for the relevant Bank an original or certified copy of an
      official receipt or such other evidence, if any, as is then customary,
      evidencing that such deduction or withholding has been made and has been
      accounted for to the appropriate authorities.

5.3   Qualifying Bank

      If, otherwise than as a result of the introduction of, change in, or any
      change in the interpretation, administration or application of, any law or
      regulation or any practice or concession of the United Kingdom Inland
      Revenue occurring after the date of this Guarantee, a Bank is not or
      ceases to be a Qualifying Bank, Holdco will not be liable to pay to that
      Bank under Clause 5.1 (Gross-up) any amount in respect of taxes levied or
      imposed by the United Kingdom or any taxing authority of or in the United
      Kingdom in excess of the amount it would have been obliged to pay if that
      Bank had been, or had not ceased to be a Qualifying Bank.
<PAGE>

                                       23


5.4   Tax Credits

      If:

      (a)   Holdco makes a payment under Clause 5.1 (Gross-up) (a "Tax Payment")
            in respect of a payment to any Bank under this Guarantee; and

      (b)   that Bank determines that it has obtained a refund of tax or
            obtained and used a credit against, or relief or remission or
            repayment of tax on its overall net income (a "Tax Credit") which in
            that Bank's opinion is reasonably determined to be attributable to
            that Tax Payment,

      then, if in its absolute discretion it can do so without any adverse
      consequences for that Bank, that Bank shall reimburse Holdco such amount
      as it reasonably determines to be such proportion of that Tax Credit as
      will leave it (after that reimbursement) in no better or worse position
      than it would have been in if no Tax Payment had been required. A Bank
      shall have an absolute discretion as to whether to claim any Tax Credit
      (and, if it does claim, the extent, order and manner in which it does so)
      and whether any amount is due from it under this Clause 5.4 (Tax Credits)
      (and, if so, what amount and when). A Bank shall not be obliged to
      disclose any information regarding its tax affairs and computations.

7.8   Negative Pledge

      Holdco will not create or permit to subsist any Security Interest on any
      of its assets.

8.    CURRENCY INDEMNITY

(a)   If a Finance Party receives an amount in respect of Holdco's liability
      under the Finance Documents or if that liability is converted into a
      claim, proof, judgment or order in a currency other than the currency (the
      "contractual currency") in which the amount is expressed to be payable
      under the relevant Finance Document:

      (i)   Holdco shall indemnify that Finance Party as an independent
            obligation against any loss or liability arising out of or as a
            result of the conversion;

      (ii)  if the amount received by that Finance Party, when converted into
            the contractual currency at a market rate in the usual course of its
            business, is less than the amount owed in the contractual currency,
            Holdco shall forthwith on demand pay to that Finance Party an amount
            in the contractual currency equal to the deficit; and

      (iii) Holdco shall pay to the Finance Party concerned on demand any
            exchange costs and taxes payable in connection with any such
            conversion.

(b)   Holdco waives any right it may have in any jurisdiction to pay any amount
      under the Finance Documents in a currency other than that in which it is
      expressed to be payable.

9.    EVIDENCE AND CALCULATIONS AND EXPENSES

      Holdco may not assign, transfer, novate or dispose of any of, or any
      interest in, its rights and/or obligations under this Guarantee.

      to which it has transferred any part of its rights and obligations under
      the Credit Agreement.

12.   DISCLOSURE OF INFORMATION

      A Bank may disclose to its professional advisers, any of its Affiliates
      or, subject (other than if a Default is outstanding) to the Company's
      prior written consent (which shall not be unreasonably withheld or
      delayed), any person with whom it is proposing to enter, or has entered

13.   SET-OFF

      A Finance Party may set off any matured obligation owed by Holdco under

      against any obligation (whether or not matured) owed by that Finance Party
      to Holdco, regardless of the place of payment, booking branch or currency
      of either obligation. If the obligations are in different currencies, the
      Finance Party may convert either obligation at a market rate of exchange
      in its usual course of business for the purpose of the set-off. If either
      obligation is unliquidated or unascertained, the Finance Party may set off
      in an amount estimated by it in good faith to be the amount of that
      obligation.

      Supplement. Upon the issue by the Issuer of any Notes expressed to be
      constituted by this Trust Deed, such Notes shall forthwith be constituted

      of Clauses 3 to 15 and Schedule 3 (all inclusive) shall apply mutatis

      constituted by a separate trust pursuant to sub-Clause 2.3 and that,
      unless expressly provided, events affecting one Series shall not affect
      any other.

2.3   Covenant to Pay: The Issuer shall on any date when any Notes become due to
      be redeemed, in whole or in part, unconditionally pay to or to the order
      of the Trustee in the Contractual Currency in the principal financial
      centre for the Contractual Currency in same day funds the Redemption
      Amount of the Notes becoming due for redemption on that date together with
      any applicable premium and shall (subject to the Conditions) until such
      payment (both before and after judgment) unconditionally so pay to or to
      the order of the Trustee interest on the principal amount of the Notes
      outstanding as set out in the Conditions (subject to sub-Clause 2.6)
      provided that (1) payment of any sum due in respect of the Notes made to
      the Issuing and Paying Agent as provided in the Agency Agreement shall, to
      that extent, satisfy such obligation except to the extent that there is
      failure in its subsequent payment to the relevant Noteholders or
      Couponholders under the Conditions and (2) a payment made after the due
      date or as a result of the Note becoming repayable following an Event of
      Default shall be deemed to have been made when the full amount due has
      been received by the Issuing and Paying Agent or the Trustee and notice to
      that effect has been given to the Noteholders (if required under Clause
      6.11), except to the extent that there is failure in its subsequent
      payment to the relevant Noteholders or Couponholders under the Conditions.
      This covenant shall only have effect each time Notes are issued and
      outstanding, when the Trustee shall hold the benefit of this covenant on
      trust for the Noteholders and Couponholders of the relevant Series.

2.4   Discharge: Subject to sub-Clause 2.5, any payment to be made in respect of
      the Notes, Receipts or the Coupons by the Issuer or the Trustee may be
      made as provided in the Conditions and any payment so made shall (subject
      to sub-Clause 2.5) to that extent be a good discharge to the Issuer or the
      Trustee, as the case may be.

                  remuneration and expenses of the Paying Agents and the

                  of this Trust Deed) and thereafter to hold all Notes,

                  Talons to the Trustee or as the Trustee directs in such notice
                  save for documents required to be retained by the Agents by
                  law or regulation; and

      2.5.2 by notice in writing to the Issuer require it to make all subsequent
            payments in respect of the Notes, Receipts, Coupons and Talons to or
            to the order of the Trustee and not to the Issuing and Paying Agent.

2.6   Rate of Interest After a Default: If the Notes bear interest at a floating
      or other variable rate and they become immediately payable under the
      Conditions, the rate of interest payable in respect of them shall continue
      to be calculated by the Calculation Agent in accordance with the
      Conditions (with consequential amendments as necessary) except that the
      rates of interest need not be published unless the Trustee otherwise
      requires. The first period in respect of which interest shall be so
      calculable shall commence on the expiry of the Interest Period during
      which the Notes become so repayable.

3     Form of the Notes

3.1   The Global Notes: The Notes shall initially be represented by a temporary
      Global Note, a permanent Global Note or one or more Certificates in the
      principal amount of the Tranche being issued. Interests in temporary
      Global Notes shall be exchangeable for Definitive Notes, Registered Notes
      or interests in permanent Global Notes as set out in each temporary Global
      Note. Interests in permanent Global Notes shall be exchangeable for
      Definitive Notes and/or Registered Notes as set out in each permanent
      Global Note.

3.2   The Definitive Notes: The Definitive Notes, Receipts, Coupons and Talons
      shall be security printed and the Certificates shall be printed, in each
      case in accordance with applicable legal and stock exchange requirements

      Certificates (other than Global Certificates) shall be endorsed with the

      or Talons he no longer holds that office. Notes, Certificates, Receipts,
      Coupons and Talons so executed and authenticated shall be or, in the case
      of Certificates, represent binding and valid obligations of the Issuer.

4.1   Stamp Duties: The Issuer shall pay any stamp, issue, documentary or other
      taxes and duties, including interest and penalties, payable in Belgium,
      Luxembourg, the United Kingdom and the country of each Contractual
      Currency in respect of the creation, issue and offering of the Notes,
      Certificates, Receipts, Coupons and Talons and the execution or delivery
      of this Trust Deed. The Issuer shall also indemnify the Trustee, the
      Noteholders and the Couponholders from and against all stamp, issue,
      documentary or other taxes paid by any of them in any jurisdiction in
      connection with any action taken by or on behalf of the Trustee or, as the
      case may be, the Noteholders or the Couponholders to enforce the Issuer's
      obligations under this Trust Deed or the Notes, Certificates, Receipts,
      Coupons or Talons.

4.2   Change of Taxing Jurisdiction: If the Issuer becomes subject generally to
      the taxing jurisdiction of a territory or a taxing authority of or in that
      territory with power to tax other than or in addition to the United
      Kingdom or any such authority of or in such territory then the Issuer
      shall (unless the Trustee otherwise agrees) give the Trustee an
      undertaking satisfactory to the Trustee in terms corresponding to the
      terms of Condition 8 with the substitution for, or (as the case may
      require) the addition to, the references in that Condition to the United
      Kingdom of references to that other or additional territory or authority
      to whose taxing jurisdiction the Issuer has become so subject. In such
      event this Trust Deed and the Notes, Certificates, Receipts, Coupons and
      Talons shall be read accordingly.

5     Application of moneys received by the Trustee

5.1   Declaration of Trust: All moneys received by the Trustee in respect of the
      Notes or amounts payable under this Trust Deed shall, despite any
      appropriation of all or part of them by the Issuer, be held by the Trustee
      on trust to apply them (subject to Clause 5.2):

            first, in payment of all costs, charges, expenses and liabilities
            incurred by the Trustee (including remuneration payable to it) in
            carrying out its functions under this Trust Deed;

            secondly, in payment of any amounts owing in respect of the Notes,
            Receipts or Coupons pari passu and rateably; and

            thirdly, in payment of any balance to the Issuer for itself.

      If the Trustee holds any moneys in respect of Notes, Receipts or Coupons
      that have become void or in respect of which claims have become
      prescribed, the Trustee shall hold them on these trusts.

5.2   Accumulation: If the amount of the moneys at any time available for
      payment in respect of the Notes under sub-Clause 5.1 is less than 10 per
      cent of the principal amount of the Notes then outstanding, the Trustee
      may, at its discretion, invest such moneys. The Trustee may retain such
      investments and accumulate the resulting income until the investments and
      the accumulations, together with any other funds for the time being under
      its control and available for such payment, amount to at least 10 per cent
      of the principal amount of the Notes then outstanding and then such
      investments, accumulations and funds (after deduction of, or provision
      for, any applicable taxes) shall be applied as specified in sub-Clause
      5.1.

<PAGE>

5.3   Investment: Moneys held by the Trustee may be invested in its name or
      under its control in any investments or other assets anywhere whether or
      not they produce income or deposited in its name or under its control at
      such bank or other financial institution in such currency as the Trustee
      may, in its absolute discretion, think fit. If that bank or institution is
      the Trustee or a subsidiary, holding or associated company of the Trustee,
      it need only account for an amount of interest equal to the largest amount
      of interest payable by it on such a deposit to an independent customer.
      The Trustee may at any time vary or transpose any such investments or
      assets or convert any moneys so deposited into any other currency, and
      shall not be responsible for any resulting loss, whether by depreciation
      in value, change in exchange rates or otherwise.

6     Covenants

      it shall:

6.1   at all times carry on and conduct its affairs in a proper manner;

6.2   so far as permitted by applicable law, give to the Trustee such
      information as it shall require and in such form as it shall require

      purpose of the discharge or exercise of the duties, trusts, powers,
      authorities and discretions vested in it under these presents or by
      operation of law;

6.3   cause to be prepared and certified by the Auditors in respect of each
      financial accounting period accounts in such form as will comply with all
      relevant legal and accounting requirements and all requirements for the

      writing to the Issuer that it has reasonable grounds to believe that an
      Event of Default or a Potential Event of Default has or may have occurred
      and so far as permitted by applicable law allow and procure its Principal
      Subsidiaries to allow the Trustee and any person appointed by the Trustee
      to whom the Issuer or the relevant Principal Subsidiary (as the case may
      be) shall have no reasonable objection, upon reasonable notice, free
      access to such books of account at all reasonable times during normal
      business hours for the purpose of the discharge or exercise of the duties,
      trusts, powers, authorities and discretions vested in it under these
      presents or by operation of law;

6.5   send to the Trustee (in addition to any copies to which it may be entitled
      as a holder of any securities of the Issuer) four copies in English of
      every balance sheet, profit and loss account, report, circular and notice
      of general meeting and every other document issued or sent to its
      shareholders together with any of the foregoing, and every document issued
      or sent to its creditors (or any class thereof) generally concerning the

      their capacities as such, as soon as practicable after the issue or
      publication thereof;

6.6   give notice in writing to the Trustee of the occurrence of any Event of
      Default or any Potential Event of Default immediately upon becoming aware
      of the same;

6.7   send to the Trustee (a) within 14 days after demand by the Trustee
      therefor and (b) (without the necessity for any such demand) promptly

      pay the Trustee as remuneration for its services as Trustee such sum on
      such dates in each case as the Issuer and the Trustee may from time to
      time agree. Such remuneration shall accrue from day to day from the date

      Trust Deed, the Issuer shall pay such additional remuneration as they may
      agree or, failing agreement as to any of the matters in this sub-Clause

      the time being of The Law Society of England and Wales. The expenses
      involved in such nomination and such merchant bank's fee shall be shared
      equally between the Trustee and the Issuer. The determination of such
      merchant bank shall be conclusive and binding on the Issuer, the Trustee,
      the Noteholders and the Couponholders.

7.3   Expenses: The Issuer shall also on demand by the Trustee pay or discharge

            per annum over the base rate of National Westminster Bank PLC on the
            date on which the Trustee made such payments; and

      7.3.2 in other cases, carry interest at such rate from 30 days after the
            date of the demand or (where the demand specifies that payment is to
            be made on an earlier date) from such earlier date.

7.4   Indemnity: The Issuer shall indemnify the Trustee in respect of all
      liabilities and expenses incurred by it or by anyone appointed by it or to
      whom any of its functions may be delegated by it in the carrying out of
      its functions and against any loss, liability, proper cost, claim, action,
      demand or expense (including, but not limited to, all proper costs,
      charges and expenses paid or incurred in disputing or defending any of the
      foregoing) that any of them may incur or that may be made against any of
      them arising out of or in relation to or in connection with, its
      appointment or the exercise of its functions.

7.5   Continuing Effect: Sub-clauses 7.3 and 7.4 shall continue in full force
      and effect as regards the Trustee even if it no longer is Trustee.

      the Notes of any two or more Series.

      obtained from, any expert and shall not be responsible to anyone for any
      loss occasioned by so acting provided it shall have exercised proper care
      in the selection of such person. Any such opinion, advice or information
      may be sent or obtained by letter, telex or fax and the Trustee shall not

      having acted in good faith on a resolution purporting to have been passed

8.3   Certificate Signed by Directors: If the Trustee, in the exercise of its
      functions, requires to be satisfied or to have information as to any fact

      by any two Directors of the Issuer as to that fact or to the effect that,

      further evidence and shall not be responsible for any loss occasioned by
      acting on such a certificate.

      conduct, or concur in transacting or conducting, any business and to do or
      concur in doing all acts required to be done by the Trustee (including the
      receipt and payment of money). Provided that it shall have exercised
      proper care in the selection of such person, the Trustee shall not be
      responsible to anyone for any misconduct or omission by any such agent so

      such agent.

8.7   Delegation: Whenever it considers it expedient in the interests of the
      Noteholders, the Trustee may delegate to any person on any terms

      Couponholders, the Trustee may determine all questions and doubts arising
      in relation to any of the provisions of this Trust Deed. Such

      implied in the acts or proceedings of the Trustee, shall be conclusive and

      Trustee having consulted the Issuer (if the Trustee reasonably believes
      such consultation to be in the interests of the Noteholders) but having

      date so specified shall be binding on the Issuer, the Noteholders and the
      Couponholders.

      Noteholders and the Couponholders.

8.13  Payment for and Delivery of Notes: The Trustee shall not be responsible

      responsibility for the correctness of the recitals to this Trust Deed,
      which shall be taken as statements of the Issuer, and shall not by the

      presents or to take any steps to ascertain whether any Event of Default,
      Potential Event of Default, Restructuring Event, Potential Restructuring
      Event (as defined in Clause 6.24) or Negative Rating Event has happened
      and, until it shall have actual knowledge or express notice to the

<PAGE>

      assume that no Event of Default, Potential Event of Default, Restructuring
      Event, Potential Restructuring Event (as defined in Clause 6.24) or
      Negative Rating Event has happened and that the Issuer is observing and
      performing all its obligations under this Trust Deed, the Notes, the
      Receipts, the Coupons and the Talons.

9     Trustee liable for negligence

      If the Trustee fails to show the degree of care and diligence required of
      it as trustee having regard to the provisions of the Trust Deed conferring
      on it powers, duties and discretions, nothing in this Trust Deed shall
      relieve or indemnify it from or against any liability that would otherwise
      attach to it in respect of any negligence, default, breach of duty or
      breach of trust of which it may be guilty.

10    Waiver and proof of default

10.1  Waiver: The Trustee may, without the consent of the Noteholders or
      Couponholders and without prejudice to its rights in respect of any
      subsequent breach, from time to time and at any time, if in its opinion
      the interests of the Noteholders will not be materially prejudiced
      thereby, waive or authorise, on such terms as seem expedient to it, any
      breach or proposed breach by the Issuer of this Trust Deed or the
      Conditions or determine that an Event of Default or Potential Event of
      Default shall not be treated as such provided that the Trustee shall not
      do so in contravention of an express direction given by an Extraordinary
      Resolution or a request made pursuant to Condition 10. No such direction
      or request shall affect a previous waiver, authorisation or determination.
      Any such waiver, authorisation or determination shall be binding on the
      Noteholders and the Couponholders and, if the Trustee so requires, shall
      be notified to the Noteholders as soon as practicable.

10.2  Proof of Default: Proof that the Issuer has failed to pay a sum due to the
      holder of any one Note, Receipt or Coupon shall (unless the contrary be
      proved) be sufficient evidence that it has made the same default as
      regards all other Notes, Receipts or Coupons that are then payable.

11    Trustee not precluded from entering into contracts

      The Trustee and any other person, whether or not acting for itself, may
      acquire, hold or dispose of any Note, Receipt, Coupon, Talon or other
      security (or any interest therein) of the Issuer or any other person, may
      enter into or be interested in any contract or transaction with any such
      person and may act on, or as depositary or agent for, any committee or
      body of holders of any securities of any such person in each case with the
      same rights as it would have had if the Trustee were not acting as Trustee
      and need not account for any profit.

12    Modification and Substitution

12.1  Modification: The Trustee may agree without the consent of the Noteholders
      or Couponholders to any modification to this Trust Deed which is of a
      formal, minor or technical nature or to correct a manifest error. The
      Trustee may also so agree to any modification to this Trust Deed that is
      in its opinion not materially prejudicial to the interests of the
      Noteholders, but such power does not extend to any such modification as is
      mentioned in paragraphs 2.2 and 2.8 of Schedule 3.

12.2  Substitution:

      12.2.1 The Trustee may, without the consent of the Noteholders or
             Couponholders, agree to the substitution of any company (the
             "Substituted Obligor") in place of the Issuer (or of any previous
             substitute under this sub-Clause) as the principal debtor under
             this Trust Deed, the Notes, the Receipts, the Coupons and the
             Talons provided that:

                                       16
<PAGE>

            (i)   a deed is executed or undertaking given by the Substituted
                  Obligor to the Trustee, in form and manner satisfactory to the
                  Trustee, agreeing to be bound by this Trust Deed, the Notes,
                  the Receipts, the Coupons and the Talons (with consequential
                  amendments as the Trustee may deem appropriate) as if the
                  Substituted Obligor had been named in this Trust Deed, the
                  Notes, the Certificates, the Receipts, the Coupons and the
                  Talons as the principal debtor in place of the Issuer;

            (ii)  if the Substituted Obligor is subject generally to the taxing
                  jurisdiction of a territory or any authority of or in that
                  territory with power to tax (the "Substituted Territory")
                  other than the territory to the taxing jurisdiction of which
                  (or to any such authority of or in which) the Issuer is
                  subject generally (the "Issuer's Territory"), the Substituted
                  Obligor shall (unless the Trustee otherwise agrees) give to
                  the Trustee an undertaking satisfactory to the Trustee in
                  terms corresponding to Condition 8 with the substitution for
                  the references in that Condition to the Issuer's Territory of
                  references to the Substituted Territory whereupon the Trust
                  Deed, the Notes, the Certificates, the Receipts, the Coupons
                  and the Talons shall be read accordingly;

            (iii) if any two Directors of the Substituted Obligor certify that
                  it will be solvent immediately after such substitution, the
                  Trustee need not have regard to the Substituted Obligor's
                  financial condition, profits or prospects or compare them with
                  those of the Issuer; and

            (iv)  the Issuer and the Substituted Obligor comply with such other
                  requirements as the Trustee may direct in the interests of the
                  Noteholders.

      12.2.2 Release of Substituted Issuer: An agreement by the Trustee
             pursuant to sub-Clause 12.2 shall, if so expressed, release the
             Issuer (or a previous substitute) from any or all of its
             obligations under this Trust Deed, the Notes, the Receipts, the
             Coupons and the Talons. Notice of the substitution shall be given
             to the Noteholders within 14 days of the execution of such
             documents and compliance with such requirements.

      12.2.3 Completion of Substitution: On completion of the formalities set
             out in sub-Clause 12.2, the Substituted Obligor shall be deemed to
             be named in this Trust Deed, the Notes, the Certificates, the
             Receipts, the Coupons and the Talons as the principal debtor in
             place of the Issuer (or of any previous substitute) and this Trust
             Deed, the Notes, the Certificates, the Receipts, the Coupons and
             the Talons shall be deemed to be amended as necessary to give
             effect to the substitution.

13    Appointment, Retirement and Removal of the Trustee

13.1  Appointment: The Issuer has the power of appointing new trustees but
      no-one may be so appointed unless previously approved by an Extraordinary
      Resolution. A trust corporation shall at all times be a Trustee and may be
      the sole Trustee. Any appointment of a new Trustee shall be notified by
      the Issuer to the Noteholders as soon as practicable.

13.2  Retirement and Removal: Any Trustee may retire at any time on giving at
      least 3 months' written notice to the Issuer without giving any reason or
      being responsible for any costs occasioned by such retirement and the
      Noteholders may by Extraordinary Resolution remove any Trustee provided
      that the retirement or removal of a sole trust corporation shall not be
      effective until a trust corporation is appointed as successor Trustee. If
      a sole trust corporation gives notice of retirement or an Extraordinary
      Resolution is passed for its removal, it shall use all reasonable
      endeavours to procure that another trust corporation be appointed as
      Trustee.

                                       17
<PAGE>

13.3  Co-Trustees: The Trustee may, despite sub-Clause 13.1, by written notice
      to the Issuer appoint anyone to act as an additional Trustee jointly with
      the Trustee:

      13.3.1 if the Trustee considers the appointment to be in the interests of
             the Noteholders and/or the Couponholders;

      13.3.2 to conform with a legal requirement, restriction or condition in a
             jurisdiction in which a particular act is to be performed; or

      13.3.3 to obtain a judgment or to enforce a judgment or any provision of
             this Trust Deed in any jurisdiction.

      Subject to the provisions of this Trust Deed the Trustee may confer on any
      person so appointed such functions as it thinks fit. The Trustee may by
      written notice to the Issuer and that person so remove that person. At the
      Trustee's request, the Issuer shall forthwith do all things as may be
      required to perfect such appointment or removal and it irrevocably
      appoints the Trustee as its attorney in its name and on its behalf to do
      so.

13.4  Competence of a Majority of Trustees: If there are more than two Trustees
      the majority of them shall be competent to perform the Trustee's functions
      provided the majority includes a trust corporation.

14    Notes held in Clearing Systems and Couponholders

14.1  Notes Held in Clearing Systems: So long as any Global Note is, or any
      Notes represented by a Global Certificate are, held on behalf of a
      clearing system, in considering the interests of Noteholders, the Trustee
      may have regard to any information provided to it by such clearing system
      or its operator as to the identity (either individually or by category) of
      its accountholders or participants with entitlements to any such Global
      Note or the Registered Notes and may consider such interests on the basis
      that such accountholders or participants were the holder(s) thereof.

14.2  Couponholders: No notices need be given to Couponholders. They shall be
      deemed to have notice of the contents of any notice given to Noteholders.
      Even if it has express notice to the contrary, in exercising any of its
      functions by reference to the interests of the Noteholders, the Trustee
      shall assume that the holder of each Note is the holder of all Receipts,
      Coupons and Talons relating to it.

15    Currency Indemnity

15.1  Currency of Account and Payment: The Contractual Currency is the sole
      currency of account and payment for all sums payable by the Issuer under
      or in connection with this Trust Deed, the Notes, the Receipts and the
      Coupons, including damages.

15.2  Extent of Discharge: An amount received or recovered in a currency other
      than the Contractual Currency (whether as a result of, or of the
      enforcement of, a judgment or order of a court of any jurisdiction, in the
      winding-up or dissolution of the Issuer or otherwise), by the Trustee or
      any Noteholder or Couponholder in respect of any sum expressed to be due
      to it from the Issuer shall only discharge the Issuer to the extent of the
      Contractual Currency amount that the recipient is able to purchase with
      the amount so received or recovered in that other currency on the date of
      that receipt or recovery (or, if it is not practicable to make that
      purchase on that date, on the first date on which it is practicable to do
      so).

15.3  Indemnity: If that Contractual Currency amount is less than the
      Contractual Currency amount expressed to be due to the recipient under
      this Trust Deed, the Notes, the Receipts or the


- --------------------------------------------------------------------------------
                                       18
<PAGE>

      Coupons, the Issuer shall indemnify it against any loss sustained by it as
      a result. In any event, the Issuer shall indemnify the recipient against
      the cost of making any such purchase.

15.4  Indemnity Separate: The indemnities in this Clause 15 and in sub-Clause
      7.4 constitute separate and independent obligations from the other
      obligations in this Trust Deed, shall give rise to a separate and
      independent cause of action, shall apply irrespective of any indulgence
      granted by the Trustee and/or any Noteholder or Couponholder and shall
      continue in full force and effect despite any judgment, order, claim or
      proof for a liquidated amount in respect of any sum due under this Trust
      Deed, the Notes, the Receipts and/or the Coupons or any other judgment or
      order.

16    Communications

16.1  Method: Each communication under this Trust Deed shall be made by telex,
      fax or otherwise in writing. Each communication or document to be
      delivered to any party under this Trust Deed shall be sent to that party
      at the telex, fax number or address, and marked for the attention of the
      person (if any), from time to time designated by that party to the other
      party for the purpose of this Trust Deed. The initial telephone number,
      telex number, fax number, address and person so designated by the parties
      under this Trust Deed are set out in the Procedures Memorandum.

16.2  Deemed Receipt: Any communication from any party to the other under this
      Trust Deed shall be effective, (if by telex) when a confirmed answerback
      is received at the end of the transmission, (if by fax) when good receipt
      is confirmed by the recipient following enquiry by the sender and (if in
      writing) when delivered, except that a communication received outside
      normal business hours shall be deemed to be received on the next business
      day in the city in which the recipient is located.

17    Governing Law and Jurisdiction

17.1  Governing Law: This Trust Deed shall be governed by and construed in
      accordance with English law.

17.2  Jurisdiction: The courts of England are to have jurisdiction to settle any
      disputes that may arise out of or in connection with this Trust Deed, the
      Notes, the Receipts, the Coupons or the Talons and accordingly any legal
      action or proceedings arising out of or in connection with this Trust
      Deed, the Notes, the Receipts, the Coupons or the Talons ("Proceedings")
      may be brought in such courts. The Issuer irrevocably submits to the
      jurisdiction of such courts and waives any objections to Proceedings in
      such courts on the ground of venue or on the ground that the Proceedings
      have been brought in an inconvenient forum. This submission is for the
      benefit of each of the Trustee, the Noteholders and the Couponholders and
      shall not limit the right of any of them to take Proceedings in any other
      court of competent jurisdiction nor shall the taking of Proceedings in any
      one or more jurisdictions preclude the taking of Proceedings in any other
      jurisdiction (whether concurrently or not).

17.3  Service of Process: The Issuer shall procure that its London office, whose
      address is at 54 Queen Anne Street, London W1M 9LA will act as its agent
      for service of process in any Proceedings in England. Such service shall
      be deemed completed on delivery to such process agent (whether or not it
      is forwarded to and received by the Issuer). If for any reason such
      process agent ceases to be able to act as such or no longer has an address
      in England the Issuer irrevocably agrees to appoint a substitute process
      agent acceptable to the Trustee and shall immediately notify the Trustee
      of such appointment. Nothing shall affect the right to serve process in
      any other manner permitted by law.

Schedule 3 to the Agency Agreement with respect thereto and that no contrary
advice as to the contents thereof has been received by Euroclear or Cedel Bank,
as the case may be.

Upon the whole or a part of this temporary Global Note being exchanged for a
permanent Global Note, such permanent Global Note shall be exchangeable in
accordance with its terms for Definitive Notes or Registered Notes.

The Definitive Notes or the Certificates representing the Registered Notes for

requirements and shall be substantially in the form set out in the Schedules to
the Trust Deed as supplemented and/or modified and/or superseded by the terms of
the Second Schedule hereto. Certificates issued upon exchange for Registered
Notes shall not be Global Certificates unless the holder so requests and
certifies to the Issuing and Paying Agent that it is, or is acting as a nominee
for, Cedel Bank, Euroclear and/ or any other clearing system.

On any exchange of a part of this temporary Global Note for an equivalent
interest in a permanent Global Note, for Definitive Notes or for Registered
Notes, as the case may be, the portion of the principal amount hereof so
exchanged shall be endorsed by or on behalf of the Issuing and

Except as otherwise specified herein, this temporary Global Note is subject to
the Conditions and the Trust Deed and, until the whole of this temporary Global
Note is exchanged for equivalent interests in a permanent Global Note, for
Definitive Notes or for Registered Notes, as the case may be, the holder of this
temporary Global Note shall in all respects be entitled to the same benefits as
if it were the holder of the permanent Global Note (or the relevant part of it)
or the Definitive Notes, as the case may be, for which it may be exchanged as if
such permanent Global Note or Definitive Notes had been issued on the Issue
Date.

Payments

No person shall be entitled to receive any payment in respect of the Notes
represented by this temporary Global Note that falls due on or after the
Exchange Date unless, upon due presentation of this temporary Global Note for
exchange, delivery of (or, in the case of a subsequent exchange, due endorsement
of) a permanent Global Note or delivery of Definitive Notes or Certificates, as
the case may be, is improperly withheld or refused by or on behalf of the
Issuer.

Payments due before the Exchange Date shall only be made in relation to such
principal amount of this temporary Global Note with respect to which there shall
have been Certification dated no earlier than such due date for payment.

Any payments that are made in respect of this temporary Global Note shall be
made to its holder against presentation and (if no further payment falls to be
made on it) surrender of it at the specified office of the Issuing and Paying
Agent or of any other Paying Agent provided for in the Conditions. If any
payment in full of principal is made in respect of any Note represented by this
temporary Global Note, the portion of this temporary Global Note representing
such Note shall be cancelled and the amount so cancelled shall be endorsed by or
on behalf of the Issuing and Paying Agent in the First Schedule hereto (such
endorsement being prima facie evidence that the payment in question has been
made) whereupon the principal amount hereof shall be reduced for all purposes by
the amount so cancelled and endorsed. If any other payments are made in respect
of the Notes represented by this temporary Global Note, a record of each such
payment shall be endorsed by or on behalf of the Issuing and Paying Agent on an
additional schedule hereto (such endorsement being prima facie evidence that the
payment in question has been made).

Cancellation

Cancellation of any Note represented by this temporary Global Note that is
required by the Conditions to be cancelled (other than upon its redemption)
shall be effected by reduction in the principal amount of this temporary Global
Note representing such Note on its presentation to or to the order of the
Issuing and Paying Agent for endorsement in the First Schedule hereto, whereupon
the principal amount hereof shall be reduced for all purposes by the amount so
cancelled and endorsed.

temporary Global Note may be given by their being delivered (so long as this
temporary Global Note is held on behalf of Euroclear and Cedel Bank or any other
clearing system) to Euroclear, Cedel Bank or such other clearing system, as the
case may be, or otherwise to the holder of this temporary Global Note, rather
than by publication as required by the Conditions.

Exchange

This permanent Global Note is exchangeable (free of charge to the holder) on or

an Exchangeable Bearer Note) Registered Notes represented by the Certificates
described below:

      (i)   by the Issuer giving notice to the Issuing and Paying Agent and the
            Noteholders of its intention to effect such exchange

      (ii)  if the Third Schedule hereto provides that this permanent Global
            Note is exchangeable for Definitive Notes at the request of the
            holder, by such holder giving notice to the Issuing and Paying Agent
            of its election for such exchange

      (iii) if this permanent Global Note is an Exchangeable Bearer Note, by the

            election to exchange the whole or a part of this permanent Global

            Euroclear or Cedel Bank or any other clearing system (an
            "Alternative Clearing System") and any such clearing system is
            closed for business for a continuous period of 14 days (other than
            by reason of holidays, statutory or otherwise) or announces an
            intention permanently to cease business or does in fact do so.

This permanent Global Note is exchangeable in part (provided, however, that if
this permanent Global Note is held by or on behalf of Euroclear and/or Cedel

Subject as provided in the Conditions applicable to Party-paid Notes, any such
exchange may be effected on or after an Exchange Date by the holder of this
permanent Global Note surrendering this permanent Global Note or, in the case of

thereof to be exchanged, the Issuer shall deliver, or procure the delivery of,
duly executed and authenticated Definitive Notes and/or (if this permanent
Global Note is an Exchangeable Bearer Note) Certificates in an aggregate
principal amount equal to the principal amount of this permanent Global Note
submitted for exchange (if appropriate, having attached to them all Coupons
(and, where appropriate, Talons) in respect of interest, and all Receipts in
respect of Instalment Amounts, that have not already been paid on this permanent
Global Note), security printed or, in the case of Certificates, printed in
accordance with any applicable legal and stock

exchange requirements and substantially in the form set out in Schedule 2 to the
Trust Deed as supplemented and/or modified and/or superseded by the terms of the
Third Schedule hereto. Certificates issued upon exchange for Registered Notes
shall not be Global Certificates unless the holder so requests and certifies to
the Issuing and Paying Agent that it is, or is acting as a nominee for, Cedel
Bank, Euroclear and/or an Alternative Clearing System.

On any exchange of a part of this permanent Global Note the portion of the
principal amount hereof so exchanged shall be endorsed by or on behalf of the
Issuing and Paying Agent in the First Schedule hereto, whereupon the principal
amount hereof shall be reduced for all purposes by the amount so exchanged and
endorsed.

Benefit of Conditions

Except as otherwise specified herein, this permanent Global Note is subject to
the Conditions and the Trust Deed and, until the whole of this permanent Global
Note is exchanged for Definitive Notes or Registered Notes, the holder of this
permanent Global Note shall in all respects be entitled to the same benefits as
if it were the holder of the Definitive Notes for which it may be exchanged and
as if such Definitive Notes had been issued on the Issue Date.

Payments

No person shall be entitled to receive any payment in respect of the Notes
represented by this permanent Global Note that falls due after an Exchange Date
for such Notes, unless upon due presentation of this permanent Global Note for
exchange, delivery of Definitive Notes or Certificates is improperly withheld or
refused by or on behalf of the Issuer or the Issuer does not perform or comply
with any one or more of what are expressed to be its obligations under any
Definitive Notes.

Payments in respect of this permanent Global Note shall be made to its holder
against presentation and (if no further payment falls to be made on it)
surrender of it at the specified office of the Issuing and Paying Agent or of
any other Paying Agent provided for in the Conditions. A record of each such
payment shall be endorsed on the First or Second Schedule hereto, as
appropriate, by the Issuing and Paying Agent or by the relevant Paying Agent,
for and on behalf of the Issuing and Paying Agent, which endorsement shall
(until the contrary is proved) be prima facie evidence that the payment in
question has been made.

Prescription

Claims in respect of principal and interest (as each is defined in the
Conditions) in respect of this permanent Global Note shall become void unless it
is presented for payment within a period of 10 years (in the case of principal)
and 5 years (in the case of interest) from the appropriate Relevant Date.

Meetings

The holder of this permanent Global Note shall (unless this permanent Global
Note represents only one Note) be treated as 2 persons for the purposes of any
quorum requirements of a meeting of Noteholders and, at any such meeting, as
having one vote in respect of each principal amount of Notes equal to the
minimum Denomination of the Notes for which this permanent Global Note may be
exchanged.

Cancellation

Cancellation of any Note represented by this permanent Global Note that is
required by the Conditions to be cancelled (other than upon its redemption)
shall be effected by reduction in the principal amount of this permanent Global
Note representing such Note on its presentation to or to the order of the
Issuing and Paying Agent for endorsement in the First Schedule hereto,


- --------------------------------------------------------------------------------
                                       27
<PAGE>

whereupon the principal amount hereof shall be reduced for all purposes by the
amount so cancelled and endorsed.

Purchase

Notes may only be purchased by the Issuer or any of its subsidiaries if they are
purchased together with the right to receive all future payments of interest and
Instalment Amounts (if any) thereon.

Issuer's Options

Any option of the Issuer provided for in the Conditions shall be exercised by
the Issuer giving notice to the Noteholders within the time limits set out in
and containing the information required by the Conditions, except that the
notice shall not be required to contain the serial numbers of Notes drawn in the
case of a partial exercise of an option and accordingly no drawing of Notes
shall be required.

Noteholders' Options

Any option of the Noteholders provided for in the Conditions may be exercised by
the holder of this permanent Global Note giving notice to the Issuing and Paying
Agent within the time limits relating to the deposit of Notes with a Paying
Agent set out in the Conditions substantially in the form of the notice
available from any Paying Agent, except that the notice shall not be required to
contain the certificate numbers of the Notes in respect of which the option has
been exercised, and stating the principal amount of Notes in respect of which
the option is exercised and at the same time presenting this permanent Global
Note to the Issuing and Paying Agent, or to a Paying Agent acting on behalf of
the Issuing and Paying Agent, for notation accordingly in the Fourth Schedule
hereto.

Notices

Notices required to be given in respect of the Notes represented by this
permanent Global Note may be given by their being delivered (so long as this
permanent Global Note is held on behalf of Euroclear, Cedel Bank or any other
clearing system) to Euroclear, Cedel Bank or such other clearing system, as the
case may be, or otherwise to the holder of this permanent Global Note, rather
than by publication as required by the Conditions.

Negotiability

This permanent Global Note is a bearer document and negotiable and accordingly:

      (i)   is freely transferable by delivery and such transfer shall operate
            to confer upon the transferee all rights and benefits appertaining

            hereto pursuant to the Conditions

      (ii)  the holder of this permanent Global Note is and shall be absolutely
            entitled as against all previous holders to receive all amounts by
            way of Redemption Amount interest or otherwise payable in respect of
            this permanent Global Note and the Issuer has waived against such
            holder and any previous holder of this permanent Global Note all
            rights of set-off or counterclaim that would or might otherwise be
            available to it in respect of the obligations evidenced by this
            Global Note and

      (iii) payment upon due presentation of this permanent Global Note as
            provided herein shall operate as a good discharge against such
            holder and all previous holders of this permanent Global Note.

                        Terms and Conditions of the Notes

The Notes are constituted by a Trust Deed (as amended or supplemented as at the
date of issue of the Notes (the "Issue Date"), the "Trust Deed") dated 4th
November 1997 between the Issuer and The Law Debenture Trust Corporation p.l.c.
(the "Trustee", which expression shall include all persons for the time being
the trustee or trustees under the Trust Deed) as trustee for the Noteholders (as
defined below). These terms and conditions include summaries of, and are subject
to, the detailed provisions of the Trust Deed, which includes the form of the
Bearer Notes, Certificates, Receipts, Coupons and Talons referred to below. An
Agency Agreement (as amended or supplemented as at the Issue Date, the "Agency
Agreement") dated 4th November 1997 has been entered into in relation to the
Notes between the Issuer, the Trustee, Morgan Guaranty Trust Company of New
York, London office as initial issuing and paying agent and the other agents
named in it. The issuing and paying agent, the paying agents, the registrar, the
transfer agents and the calculation agent(s) for the time being (if any) are
referred to below respectively as the "Issuing and Paying Agent", the "Paying
Agents" (which expression shall include the Issuing and Paying Agent), the
"Registrar", the "Transfer Agents" (which expression shall include the
Registrar) and the "Calculation Agent(s)". Copies of the relevant Pricing
Supplement, Trust Deed and the Agency Agreement are available for inspection
during usual business hours at the registered office of the Trustee (presently
at Princes House, 95 Gresham Street, London EC2V 7LY) and at the specified
offices of the Paying Agents and the Transfer Agents.

The Noteholders, the holders of the interest coupons (the "Coupons")
appertaining to interest bearing Notes in bearer form and, where applicable in
the case of such Notes, talons for further Coupons (the "Talons") (the
"Couponholders") and the holders of the receipts for the payment of instalments
of principal (the "Receipts") relating to Notes in bearer form of which the
principal is payable in instalments are entitled to the benefit of, are bound
by, and are deemed to have notice of, all the provisions of the Trust Deed and
the relevant Pricing Supplement and are deemed to have notice of those
provisions applicable to them of the Agency Agreement.

1. Form, Denomination and Title

The Notes are issued in bearer form ("Bearer Notes", which expression includes
Notes that are specified to be Exchangeable Bearer Notes), in registered form
("Registered Notes") or in bearer form exchangeable for Registered Notes
("Exchangeable Bearer Notes") in each case in the Denomination(s) shown thereon.

All Registered Notes shall have the same Denomination. Where Exchangeable Bearer
Notes are issued, the Registered Notes for which they are exchangeable shall
have the same Denomination as the lowest denomination of Exchangeable Bearer
Notes.

Bearer Notes are serially numbered and are issued with Coupons (and, where
appropriate, a Talon) attached, save in the case of Notes that do not bear
interest in which case references to interest (other than in relation to
interest due after the Maturity Date), Coupons and Talons in these Conditions
are not applicable. Any Bearer Note the principal amount of which is redeemable
in instalments is issued with one or more Receipts attached.

Registered Notes are represented by registered certificates ("Certificates")
and, save as provided in Condition 2(c), each Certificate shall represent the
entire holding of Registered Notes by the same holder.

Title to the Bearer Notes and the Receipts, Coupons and Talons shall pass by
delivery. Title to the Registered Notes shall pass by registration in the
register that the Issuer shall procure to be kept by the


- --------------------------------------------------------------------------------
                                       43
<PAGE>

Registrar in accordance with the provisions of the Agency Agreement (the
"Register"). Except as ordered by a court of competent jurisdiction or as
required by law, the holder (as defined below) of any Note, Receipt, Coupon or
Talon shall be deemed to be and may be treated as its absolute owner for all
purposes whether or not it is overdue and regardless of any notice of ownership,
trust or an interest in it, any writing on it (or on the Certificate
representing it) or its theft or loss (or that of the related Certificate) and
no person shall be liable for so treating the holder.

In these Conditions, "Noteholder" means the bearer of any Bearer Note and the
Receipts relating to it or the person in whose name a Registered Note is
registered (as the case may be), "holder" (in relation to a Note, Receipt,
Coupon or Talon) means the bearer of any Bearer Note, Receipt, Coupon or Talon
or the person in whose name a Registered Note is registered (as the case may be)
and capitalised terms have the meanings given to them hereon, the absence of any
such meaning indicating that such term is not applicable to the Notes.

2. Exchanges of Exchangeable Bearer Notes and Transfers of Registered Notes

(a) Exchange of Exchangeable Bearer Notes

Subject as provided in Condition 2(f), Exchangeable Bearer Notes may be
exchanged for the same aggregate principal amount of Registered Notes at the
request in writing of the relevant Noteholder and upon surrender of each
Exchangeable Bearer Note to be exchanged, together with all unmatured Receipts,
Coupons and Talons relating to it, at the specified office of any Transfer
Agent; provided, however, that where an Exchangeable Bearer Note is surrendered
for exchange after the Record Date (as defined in Condition 7(b)) for any
payment of interest, the Coupon in respect of that payment of interest need not
be surrendered with it. Registered Notes may not be exchanged for Bearer Notes.
Bearer Notes of one Denomination may not be exchanged for Bearer Notes of
another Denomination. Bearer Notes that are not Exchangeable Bearer Notes may
not be exchanged for Registered Notes.

(b) Transfer of Registered Notes

One or more Registered Notes may be transferred upon the surrender (at the
specified office of the Registrar or any Transfer Agent) of the Certificate
representing such Registered Notes to be transferred, together with the form of
transfer endorsed on such Certificate duly completed and executed and any other
evidence as the Registrar or Transfer Agent may reasonably require. In the case
of a transfer of part only of a holding of Registered Notes represented by one
Certificate, a new Certificate shall be issued to the transferee in respect of
the part transferred and a further new Certificate in respect of the balance of
the holding not transferred shall be issued to the transferor.

(c) Exercise of Options or Partial Redemption in Respect of Registered Notes

In the case of an exercise of an Issuer's or Noteholders' option in respect of,
or a partial redemption of, a holding of Registered Notes represented by a
single Certificate, a new Certificate shall be issued to the holder to reflect
the exercise of such option or in respect of the balance of the holding not
redeemed. In the case of a partial exercise of an option resulting in Registered
Notes of the same holding having different terms, separate Certificates shall be
issued in respect of those Notes of that holding that have the same terms. New
Certificates shall only be issued against surrender of the existing Certificates
to the Registrar or any Transfer Agent. In the case of a transfer of Registered
Notes to a person who is already a holder of Registered Notes, a new Certificate
representing the enlarged holding shall only be issued against surrender of the
Certificate representing the existing holding.

(d) Delivery of New Certificates

Each new Certificate to be issued pursuant to Conditions 2(a), (b) or (c) shall
be available for delivery within five business days of receipt of the request
for exchange, form of transfer or Exercise Notice or surrender of the
Certificate for exchange. Delivery of the new Certificate(s) shall be made at
the specified office of the Transfer Agent or of the Registrar (as the case may
be) to whom delivery or surrender of such request for exchange, form of
transfer, Exercise Notice or Certificate shall have been made or, at the option
of the holder making such delivery or surrender as aforesaid and as specified in
the relevant request for exchange, form of transfer, Exercise Notice or
otherwise in writing, be mailed by uninsured post at the risk of the holder
entitled to the new Certificate to such address as may be so specified, unless
such holder requests otherwise and pays in advance to the relevant Agent the
costs of such other method of delivery and/or such insurance as it may specify.
In this Condition 2(d), "business day" means a day, other than a Saturday or
Sunday, on which banks are open for business in the place of the specified
office of the relevant Transfer Agent or the Registrar.

(e) Exchange Free of Charge

Exchange and transfer of Notes and Certificates on registration, transfer,
exercise of an option or partial redemption shall be effected without charge by
or on behalf of the Issuer, the Registrar or the Transfer Agents, but upon
payment of any tax or other governmental charges that may be imposed in relation
to it (or the giving of such indemnity as the Registrar or the relevant Transfer
Agent may reasonably require).

                                      44
<PAGE>

(f) Closed Periods

No Noteholder may require the transfer of a Registered Note to be registered or
an Exchangeable Bearer Note to be exchanged for one or more Registered Note(s)
(i) during the period of 15 days ending on the due date for redemption of, or
payment of any Instalment Amount in respect of, that Note, (ii) during the
period of 15 days prior to any date on which Notes may be called for redemption
by the Issuer at its option pursuant to Condition 6(d), (iii) after any such
Note has been called for redemption or (iv) during the period of seven days
ending on (and including) any Record Date. An Exchangeable Bearer Note called
for redemption may, however, be exchanged for one or more Registered Note(s) in
respect of which the Certificate is simultaneously surrendered not later than
the relevant Record Date.

3. Status

The Notes and the Receipts and Coupons constitute (subject to Condition 4)
unsecured obligations of the Issuer and shall at all times rank pari passu and
without any preference among themselves. The payment obligations of the Issuer
under the Notes and the Receipts and Coupons shall, save for such exceptions as
may be provided by applicable legislation and subject to Condition 4, at all
times rank at least equally with all other unsecured and unsubordinated
indebtedness and monetary obligations of the Issuer, present and future.

4. Negative Pledge

So long as any of the Notes remains outstanding (as defined in the Trust Deed)
the Issuer will ensure that no Relevant Indebtedness of the Issuer or any
Relevant Subsidiary (as defined in Condition 6) or of any other person and no
guarantee by the Issuer or any Relevant Subsidiary of any Relevant Indebtedness
(as defined in Condition 6) of any person will be secured by a mortgage, charge,
lien, pledge or other security interest (each a "Security Interest") upon, or
with respect to, any of the present or future business, undertaking, assets or
revenues (including any uncalled capital) of the Issuer or any Relevant
Subsidiary unless the Issuer shall, before or at the same time as the creation
of the Security Interest, take any and all action necessary to ensure that:

(i) all amounts payable by it under the Notes, the Receipts, the Coupons and the
Trust Deed are secured equally and rateably with the Relevant Indebtedness or
guarantee, as the case may be, by the Security Interest to the satisfaction of
the Trustee; or

(ii) such other Security Interest or guarantee or other arrangement (whether or
not including the giving of a Security Interest) is provided in respect of all
amounts payable by the Issuer under the Notes, the Receipts, the Coupons and the
Trust Deed either (i) as the Trustee shall in its absolute discretion deem not
materially less beneficial to the interests of the Noteholders or (ii) as shall
be approved by an Extraordinary Resolution (as defined in the Trust Deed) of the
Noteholders,

save that the Issuer or any Relevant Subsidiary may create or have outstanding a
Security Interest in respect of any Relevant Indebtedness and/or any guarantees
given by the Issuer or any Relevant Subsidiary in respect of any Relevant
Indebtedness of any person (without the obligation to provide a Security
Interest or guarantee or other arrangement in respect of the Notes, the
Receipts, the Coupons and the Trust Deed as aforesaid) where (1) such Relevant
Indebtedness has an initial maturity of not less than twenty years and is of a
maximum aggregate amount outstanding at any time not exceeding the greater of
(pound)250,000,000 or 20% of the Capital and Reserves (as defined in Condition
6) or (2) such Security Interest is provided in respect of a company becoming a
Subsidiary of the Issuer after the date of the relevant Pricing Supplement and
where such Security Interest existed at the time that company becomes a
Subsidiary of the Issuer (provided that such Security Interest was not created
in contemplation of that company becoming a Subsidiary of the Issuer and the
principal amount secured at the time of that company becoming a Subsidiary of
the Issuer is not subsequently increased).

5. Interest and Other Calculations

(a) Interest Rate and Accrual

Each Note bears interest on its outstanding principal amount from the Interest
Commencement Date at the rate per annum (expressed as a percentage) equal to the
Interest Rate, such interest being payable in arrear on each Interest Payment
Date.

Interest shall cease to accrue on each Note on the due date for redemption
unless, upon due presentation, payment of principal is improperly withheld or
refused, in which event interest shall continue to accrue (as well after as
before judgment) at the Interest Rate in the manner provided in this Condition 5
to the Relevant Date (as defined in Condition 8).

(b) Business Day Convention

If any date referred to in these Conditions that is specified to be subject to
adjustment in accordance with a Business Day Convention would otherwise fall on
a day that is not a Business Day, then, if the Business Day Convention specified
is (i) the Floating Rate Business Day Convention, such date shall be postponed

                                      45
<PAGE>

to the next day that is a Business Day unless it would thereby fall into the
next calendar month, in which event (A) such date shall be brought forward to
the immediately preceding Business Day and (B) each subsequent such date shall
be the last Business Day of the month in which such date would have fallen had
it not been subject to adjustment, (ii) the Following Business Day Convention,
such date shall be postponed to the next day that is a Business Day, (iii) the
Modified Following Business Day Convention, such date shall be postponed to the
next day that is a Business Day unless it would thereby fall into the next
calendar month, in which event such date shall be brought forward to the
immediately preceding Business Day or (iv) the Preceding Business Day
Convention, such date shall be brought forward to the immediately preceding

(c) Interest Rate on Floating Rate Notes

If the Interest Rate is specified in the Pricing Supplement as being Floating
Rate, the Interest Rate for each Interest Accrual Period shall be determined by
the Calculation Agent at or about the Relevant Time on the Interest
Determination Date in respect of each Interest Accrual Period in accordance with
the following

(i) if the Primary Source for the Floating Rate is a Page, subject as provided
below, the Interest Rate shall be:

(x) the Relevant Rate (where such Relevant Rate on such Page is a composite
quotation or is customarily supplied by one entity); or

(y) the arithmetic mean of the Relevant Rates of the persons whose Relevant
Rates appear on that Page,

in each case appearing on such Page at the Relevant Time on the Interest
Determination Date

(ii) if the Page specified in the Pricing Supplement as a Primary Source
permanently ceases to quote the Relevant Rate(s) but such quotation(s) is/are
available from another page, section or other part of such information service
selected by the Calculation Agent (the "Replacement Page"), the Replacement Page
shall be substituted as the Primary Source for Interest Rate Quotations and if
no Replacement Page exists but such quotation(s) is/are available from a page,
section or other part of a different information service selected by the
Calculation Agent and approved by the Issuer (the "Secondary Replacement Page"),
the Secondary Replacement Page shall be substituted as the Primary Source for
Interest Rate Quotations

(iii) if the Primary Source for the Floating Rate is Reference Banks (as defined
below) or if sub-paragraph (i)(x) applies and no Relevant Rate appears on the
Page at the Relevant Time on the Interest Determination Date or if sub-paragraph
(i)(y) above applies and fewer than two Relevant Rates appear on the Page at the
Relevant Time on the Interest Determination Date, subject as provided below, the
Interest Rate shall be the arithmetic mean of the Relevant Rates that each of
the Reference Banks is quoting to leading banks in the Relevant Financial Centre
at the Relevant Time on the Interest Determination Date, as determined by the
Calculation Agent

(iv) if paragraph (iii) above applies, and the Calculation Agent determines that
fewer than two Reference Banks are so quoting Relevant Rates, and either the
Relevant Currency is not ECU or the Relevant Currency is ECU and the third stage
of the European monetary union has started (in which event, references to the
Relevant Currency shall mean the Euro), subject as provided below, the Interest
Rate shall be the arithmetic mean of the rates per annum (expressed as a
percentage) that the Calculation Agent determines to be the rates (being the
nearest equivalent to the Benchmark) in respect of a Representative Amount of
the Relevant Currency that at least two out of five leading banks selected by
the Calculation Agent in the principal financial centre of the country of the
Relevant Currency or, if the Relevant Currency is ECU, in Brussels, Frankfurt,
London, Luxembourg or Paris as selected by the Calculation Agent (the "Principal
Financial Centre") are quoting at or about the Relevant Time on the date on
which such banks would customarily quote such rates for a period commencing on
the Effective Date for a period equivalent to the Specified Duration (x) to
leading banks carrying on business in Europe, or (if the Calculation Agent
determines that fewer than two of such banks are so quoting to leading banks in
Europe) (y) to leading banks carrying on business in the Principal Financial
Centre; except that, if fewer than two of such banks are so quoting to leading
banks in the Principal Financial Centre, the Interest Rate shall be the Interest
Rate determined on the previous Interest Determination Date (after readjustment
for any difference between any Margin, Rate Multiplier or Maximum or Minimum
Interest Rate applicable to the preceding Interest Accrual Period and to the
relevant Interest Accrual Period)

(v) if paragraph (iii) above applies and the Relevant Currency is ECU and the
third stage of European monetary union has not started and the Calculation Agent
determines that fewer than two Reference Banks are so quoting Relevant Rates,
the Calculation Agent shall, in respect of each of the then component currencies
of the ECU (provided that, if the ECU is not then used as the unit of account of
the European Communities (the "EC"), the component currencies of the ECU shall
be those provided for in

                                      46
<PAGE>

Condition 7(i)(iv)), determine an Interest Rate (each a "Component Rate") for
such component in accordance with paragraphs (iii) and (iv) above as if such
component was the Relevant Currency (and without any adjustment in accordance
with Condition 5(e) below) and, provided that Component Rates for component
currencies representing in aggregate 95% (determined as provided below) of one
ECU are determined on the Interest Determination Date and subject as provided
below, the Interest Rate shall be the arithmetic mean of the Component Rates,
weighted in the manner provided below, as determined by the Calculation Agent
and

(vi) if paragraph (v) above applies and the Calculation Agent is unable to
determine the Interest Rate for an Interest Accrual Period in accordance with
that paragraph, the Interest Rate for such Interest Accrual Period shall be the
Interest Rate in effect for the last preceding Interest Accrual Period to which
paragraphs (i) or (iii) above shall have applied (after readjustment for any
difference between any Margin, Rate Multiplier or Maximum or Minimum Interest
Rate applicable to the preceding Interest Accrual Period and to the relevant
Interest Accrual Period).

(d) Interest Rate on Zero Coupon Notes

Where a Note the Interest Rate of which is specified in the Pricing Supplement
to be Zero Coupon is repayable prior to the Maturity Date and is not paid when
due, the amount due and payable prior to the Maturity Date shall be the
Redemption Amount of such Note. As from the Maturity Date, the Interest Rate for
any overdue principal of such a Note shall be a rate per annum (expressed as a
percentage) equal to the Amortisation Yield (as defined in Condition 6(b)).

(e) Margin, Maximum/Minimum Interest Rates, Instalment Amounts and Redemption
    Amounts, Rate Multipliers, Rounding and ECU Weighting

(i) If any Margin or Rate Multiplier is specified in the Pricing Supplement
(either (x) generally, or (y) in relation to one or more Interest Accrual
Periods), an adjustment shall be made to all Interest Rates, in the case of (x),
or the Interest Rates for the specified Interest Accrual Periods, in the case of
(y), calculated in accordance with Condition 5(c) above by adding (if a positive
number) or subtracting the absolute value (if a negative number) of such Margin
or multiplying by such Rate Multiplier, subject always to the next paragraph.

(ii) If any Maximum or Minimum Interest Rate, Instalment Amount or Redemption
Amount is specified in the Pricing Supplement, then any Interest Rate,
Instalment Amount or Redemption Amount shall be subject to such maximum or
minimum, as the case may be.

(iii) For the purposes of any calculations required pursuant to these Conditions
(unless otherwise specified in the Pricing Supplement), (x) all percentages
resulting from such calculations shall be rounded, if necessary, to the nearest
one hundred-thousandth of a percentage point (with halves being rounded up), (y)
all figures shall be rounded to seven significant figures (with halves being
rounded up) and (z) all currency amounts that fall due and payable shall be
rounded to the nearest unit of such currency (with halves being rounded up),
save in the case of yen, which shall be rounded down to the nearest yen. For
these purposes "unit" means, with respect to any currency other than ECU, the
lowest amount of such currency that is available as legal tender in the country
of such currency and, with respect to ECU, means 0.01 ECU.

(iv) For the purposes of this Condition 5, the weighting to be given to a
component currency of, or the percentage that it bears to, one ECU shall be
determined by the Calculation Agent by reference to the proportion that the
amount of such component currency included in one ECU bears to one ECU and
calculated on the basis of the U.S. dollar equivalent of each of the component
currencies as at or about the Relevant Time on the Interest Determination Date
in question. Such U.S. dollar equivalent shall be determined by the Calculation
Agent in the manner provided under Condition 7(i), except that for the purposes
of this Condition 5, (i) any reference therein to a Day of Valuation shall be
deemed to refer to the Interest Determination Date in question, (ii) all
decisions or choices to be made by the Trustee thereunder shall be made by the
Calculation Agent, and (iii) if the ECU is being used as the unit of account of
the EC on such Interest Determination Date, the components of the ECU shall be
the currency amounts that are components of the ECU on such date.

(f) Calculations

The amount of interest payable in respect of any Note for any period shall be
calculated by multiplying the product of the Interest Rate and the outstanding
principal amount of such Note by the Day Count Fraction, unless an Interest
Amount (or a formula for its calculation) is specified in respect of such
period, in which case the amount of interest payable in respect of such Note for
such period shall equal such Interest Amount (or be calculated in accordance
with such formula). Where any Interest Period comprises two or more Interest
Accrual Periods, the amount of interest payable in respect of such Interest
Period shall be the sum of the amounts of interest payable in respect of each of
those Interest Accrual Periods.

                                      47
<PAGE>

(g) Determination and Publication of Interest Rates, Interest Amounts,
    Redemption Amounts and Instalment Amounts

As soon as practicable after the Relevant Time on each Interest Determination
Date or such other time on such date as the Calculation Agent may be required to
calculate any Redemption Amount or Instalment Amount, obtain any quote or make
any determination or calculation, it shall determine the Interest Rate and
calculate the amount of interest payable (the "Interest Amounts") in respect of
each Denomination of the Notes for the relevant Interest Accrual Period,
calculate the Redemption Amount or Instalment Amount, obtain such quote or make
such determination or calculation, as the case may be, and cause the Interest
Rate and the Interest Amounts for each Interest Period and the relevant Interest
Payment Date and, if required to be calculated, the Redemption Amount or any
Instalment Amount to be notified to the Trustee, the Issuer, each of the Paying
Agents, the Noteholders, any other Calculation Agent appointed in respect of the
Notes that is to make a further calculation upon receipt of such information
and, if the Notes are listed on a stock exchange and the rules of such exchange
so require, such exchange as soon as possible after their determination but in
no event later than (i) the commencement of the relevant Interest Period, if
determined prior to such time, in the case of notification to such exchange of
an Interest Rate and Interest Amount, or (ii) in all other cases, the fourth
Business Day after such determination. Where any Interest Payment Date or
Interest Period Date is subject to adjustment pursuant to Condition 5(b), the
Interest Amounts and the Interest Payment Date so published may subsequently be
amended (or appropriate alternative arrangements made with the consent of the
Trustee by way of adjustment) without notice in the event of an extension or
shortening of the Interest Period. If the Notes become due and payable under
Condition 10, the accrued interest and the Interest Rate payable in respect of
the Notes shall nevertheless continue to be calculated as previously in
accordance with this Condition but no publication of the Interest Rate or the
Interest Amount so calculated need be made unless the Trustee otherwise
requires. The determination of each Interest Rate, Interest Amount, Redemption
Amount and Instalment Amount, the obtaining of each quote and the making of each
determination or calculation by the Calculation Agent(s) shall (in the absence
of manifest error) be final and binding upon all parties.

(h) Determination or Calculation by Trustee

If the Calculation Agent does not at any time for any reason determine or
calculate the Interest Rate for an Interest Period or any Interest Amount,
Instalment Amount or Redemption Amount, the Trustee shall do so (or shall
appoint an agent on its behalf to do so) and such determination or calculation
shall be deemed to have been made by the Calculation Agent. In doing so, the
Trustee shall apply the foregoing provisions of this Condition, with any
necessary consequential amendments, to the extent that, in its opinion, it can
do so, and, in all other respects it shall do so in such manner as it shall deem
fair and reasonable in all the circumstances.

Trust Deed). If any Reference Bank (acting through its relevant office) is
unable or unwilling to continue to act as a Reference Bank, then the Issuer
shall (with the prior approval of the Trustee) appoint another Reference Bank
with an office in the Relevant Financial Centre to act as such in its place.
Where more than one Calculation Agent is appointed in respect of the Notes,
references in these Conditions to the Calculation Agent shall be construed as
each Calculation Agent performing its respective duties under the Conditions. If
the Calculation Agent is unable or unwilling to act as such or if the
Calculation Agent fails duly to establish the Interest Rate for an Interest
Period or to calculate any Interest Amount, Instalment Amount or the Redemption
Amount or to comply with any other requirement, the Issuer shall (with the prior
approval of the Trustee) appoint a leading bank or investment banking firm
engaged in the interbank market (or, if appropriate, money, swap or
over-the-counter index options market) that is most closely connected with the
calculation or determination to be made by the Calculation Agent (acting through
its principal London office or any other office actively involved in such
market) to act as such in its place. The Calculation Agent may not resign its
duties without a successor having been appointed as aforesaid.

(k) Certificates to be Final

connection with the exercise or non-exercise by them of their powers, duties and
discretions pursuant to such provisions.

6. Redemption, Purchase and Options

(a) Redemption by Instalments and Final Redemption

(i) Unless previously redeemed, purchased and cancelled as provided in this
Condition 6 or the relevant Instalment Date (being one of the dates so specified
hereon) is extended pursuant to the Issuer's or any Noteholder's option in
accordance with Condition 6(d) or 6(e), each Note that provides for Instalment
Dates and Instalment Amounts shall be partially redeemed on each Instalment Date
at the related Instalment Amount specified in the Pricing Supplement. The
outstanding principal amount of each such Note shall be reduced by the
Instalment Amount (or, if such Instalment Amount is calculated by reference to a
proportion of the principal amount of such Note, such proportion) for all
purposes with effect from the related Instalment Date, unless payment of the
Instalment Amount is improperly withheld or refused on presentation of the
related Receipt, in which case, such amount shall remain outstanding until the
Relevant Date relating to such Instalment Amount.

(ii) Unless previously redeemed, purchased and cancelled as provided below or
its maturity is extended pursuant to the Issuer's or any Noteholder's option in
accordance with Condition 6(d) or 6(e), each Note shall be finally redeemed on
the Maturity Date specified in the Pricing Supplement at its Redemption Amount
(which, unless otherwise provided in the Pricing Supplement, is its principal
amount) or, in the case of a Note falling within paragraph (i) above, its final
Instalment Amount.

(b) Early Redemption of Zero Coupon Notes

(i) The Redemption Amount payable in respect of any Note that does not bear
interest prior to the Maturity Date, the Redemption Amount of which is not
linked to an index and/or a formula, upon redemption of such Note pursuant to
Condition 6(c) or 6(f) or upon it becoming due and payable as provided in
Condition 10 shall be the Amortised Face Amount (calculated as provided below)
of such Note.

                                      50
<PAGE>

(ii) Subject to the provisions of sub-paragraph (iii) below, the Amortised Face
Amount of any such Note shall be the scheduled Redemption Amount of such Note on
the Maturity Date discounted at a rate per annum (expressed as a percentage)
equal to the Amortisation Yield (which, if none is shown in the Pricing
Supplement, shall be such rate as would produce an Amortised Face Amount equal
to the issue price of the Notes if they were discounted back to their issue
price on the Issue Date) compounded annually. Where such calculation is to be
made for a period of less than one year, it shall be made on the basis of the
Day Count Fraction shown hereon.

(iii) If the Redemption Amount payable in respect of any such Note upon its
redemption pursuant to Condition 6(c) or 6(f) or upon it becoming due and
payable as provided in Condition 10 is not paid when due, the Redemption Amount
due and payable in respect of such Note shall be the Amortised Face Amount of
such Note as defined in sub-paragraph (ii) above, except that such sub-paragraph
shall have effect as though the reference therein to the date on which the Note
becomes due and payable were replaced by a reference to the Relevant Date. The
calculation of the Amortised Face Amount in accordance with this sub-paragraph
shall continue to be made (as well after as before judgment) until the Relevant
Date, unless the Relevant Date falls on or after the Maturity Date, in which
case the amount due and payable shall be the scheduled Redemption Amount of such
Note on the Maturity Date together with any interest that may accrue in
accordance with Condition 5(d).

(c) Redemption for Taxation Reasons

If, as a result of any amendment to or change in the laws or regulations of the
United Kingdom or of any political subdivision thereof or any authority therein
or thereof having power to tax or any change in the official or generally
accepted interpretation or application of such laws or regulations which becomes
effective on or after the date of the Trust Deed, the Issuer has or will become
obliged to pay any additional amounts as described in Condition 8 (and such
amendment or change has been evidenced by the delivery by the Issuer to the
Trustee (who shall accept such certificate and opinion as sufficient evidence
thereof) of (i) a certificate signed by two directors of the Issuer on behalf of
the Issuer stating that such amendment or change has occurred (irrespective of
whether such amendment or change is then effective), describing the facts
leading thereto and stating that such requirement cannot be avoided by the
Issuer, taking reasonable measures available to it and (ii) an opinion of
independent legal advisers of recognised standing to the effect that such
amendment or change has occurred (irrespective of whether such amendment or
change is then effective)), the Issuer may (having given not less than 30 nor
more than 90 days' notice to the Trustee and to the holders in accordance with
Condition 16) redeem all, but not some only, of the Notes (other than Notes in
respect of which the Issuer shall have given a notice of redemption pursuant to
Condition 6(d) or in respect of which a Noteholder shall have given a Put Event
Notice in accordance with Condition 6(f), in each case prior to any notice being
given under this Condition 6(c)) at their Redemption Amount, together with
accrued interest to the date fixed for such redemption, provided that no such
notice of redemption shall be given earlier than 90 days prior to the earliest
date on which the Issuer would be required to pay such additional amounts were a
payment in respect of the Notes then due.

(d) Redemption at the Option of the Issuer and Exercise of Issuer's Options

If so provided in the Pricing Supplement, the Issuer may, on giving irrevocable
notice to the Noteholders falling within the Issuer's Option Period, redeem, or
exercise the Issuer's option in relation to, all or, if so provided, some of the
Notes (other than Notes in respect of which the Issuer shall have given a notice
of redemption pursuant to Condition 6(c) or in respect of which a Noteholder
shall have given a Put Event Notice in accordance with Condition 6(f), in each
case prior to any notice being given under this Condition 6(d)) in the principal
amount or integral multiples thereof and on the date or dates so provided. Any
such redemption of Notes shall be at their Redemption Amount together with
interest accrued to the date fixed for redemption.

All Notes in respect of which any such notice is given shall be redeemed, or the
Issuer's option shall be exercised, on the date specified in such notice in
accordance with this Condition.

In the case of a partial redemption or a partial exercise of the Issuer's
option, the notice to Noteholders shall also contain the certificate numbers of
the Notes to be redeemed or in respect of which such option has been exercised,
which shall have been drawn in such place as the Trustee may approve and in such
manner as it deems appropriate, subject to compliance with any applicable laws
and stock exchange requirements. So long as the Notes are listed on the London
Stock Exchange or any other stock exchange and the rules of the relevant stock
exchange so require, the Issuer shall, once in each year in which there has been
a partial redemption of the Notes, cause to be published in a leading newspaper
of general circulation in London or as specified by such other stock exchange, a
notice specifying the aggregate principal amount of Notes outstanding and a list
of the Notes drawn for redemption but not surrendered.

(e) Redemption at the Option of Noteholders and Exercise of Noteholders' Options

If so provided in the Pricing Supplement, the Issuer shall, at the option of the
holder of any such Note, redeem such Note on the date or dates so provided at
its Redemption Amount together with interest accrued to the date fixed for
redemption.

                                      51
<PAGE>

To exercise such option or any other Noteholders' option that may be set out
hereon the holder must deposit (in the case of Bearer Notes) such Note (together
with all unmatured Receipts and Coupons and unexchanged Talons) with any Paying
Agent or (in the case of Registered Notes) the Certificate representing such
Note(s) with the Registrar or any Transfer Agent at its specified office,
together with a duly completed option exercise notice ("Exercise Notice" which
expression shall include any Put Notice (as defined below)) in the form
obtainable from any Paying Agent, the Registrar or any Transfer Agent (as
applicable) within the Noteholders' Option Period (which expression shall, in
the case of the exercise of the option referred to in Condition 6(f) below, mean
the Put Period (as defined below)). No Note or Certificate so deposited and
option exercised may be withdrawn without the prior consent of the Issuer,
except that such Note or Certificate will be returned to the relevant Noteholder
by the Paying Agent, the Registrar or Transfer Agent with which it has been
deposited if, prior to the due date for its redemption or the exercise of the
option, the Note becomes immediately due and payable or if upon due presentation
payment of the redemption moneys is not made or exercise of the option is
denied.

(f) Redemption at the Option of the Noteholders on a Put Event

If so provided in the Pricing Supplement, if, at any time while any of the Notes
remains outstanding, a Restructuring Event occurs and prior to the commencement
of or during the Restructuring Period an Independent Financial Adviser shall
have certified in writing to the Trustee that such Restructuring Event will not
be or is not, in its opinion, materially prejudicial to the interests of the
Noteholders, the following provisions of this Condition 6(f) shall cease to have
any further effect in relation to such Restructuring Event.

If, at any time while any of the Notes remains outstanding, a Restructuring
Event occurs and (subject to this Condition 6(f)) within the Restructuring
Period, either:

(i) if at the time such Restructuring Event occurs there are Rated Securities, a
Rating Downgrade in respect of such Restructuring Event also occurs; or

(ii) if at such time there are no Rated Securities, a Negative Rating Event also
occurs; and

an Independent Financial Adviser shall have certified in writing to the Trustee
that such Restructuring Event is, in its opinion, materially prejudicial to the
interests of the Noteholders (a "Negative Certification"), then, unless at any
time the Issuer shall have given a notice under Condition 6(c) or 6(d), the
holder of each Note will, upon the giving of a Put Event Notice (as defined
below), have the option (the "Put Option") to require the Issuer to redeem or,
at the option of the Issuer, purchase (or procure the purchase of) that Note on
the Put Date (as defined below), at its principal amount together with (or,
where purchased, together with an amount equal to) interest (if any) accrued to
(but excluding) the Put Date.

An event shall be deemed not to be a Restructuring Event if, notwithstanding the
occurrence of a Rating Downgrade or a Negative Rating Event, the rating assigned
to the Rated Securities by any Rating Agency is subsequently increased to, or,
as the case may be, there is assigned to the Notes or other unsecured and
unsubordinated debt of the Issuer or a Relevant Subsidiary (or of any Subsidiary
of the Issuer which is guaranteed on an unsecured and unsubordinated basis by
the Issuer or a Relevant Subsidiary) having an initial maturity of five years or
more by any Rating Agency, an investment grade rating (BBB-/Baa3 or their
respective equivalents for the time being) or better prior to any Negative
Certification being issued.

Any certification by an Independent Financial Adviser as aforesaid as to whether
or not, in its opinion any Restructuring Event is materially prejudicial to the
interests of the Noteholders shall, in the absence of manifest error, be
conclusive and binding on the Trustee, the Issuer and the Noteholders.

Promptly upon, and in any event within 14 days after, the Issuer becoming aware
that a Put Event has occurred, the Issuer shall, and at any time upon the
Trustee becoming similarly so aware the Trustee may, and if so requested by the
holders of at least one-quarter in principal amount of the Notes then
outstanding shall, give notice (a "Put Event Notice") to the Noteholders in
accordance with Condition 16 specifying the nature of the Put Event and the
procedure for exercising the Put Option.

To exercise the Put Option, the holder of a Note must deposit (in the case of a
Bearer Note) such Note with any Paying Agent or (in the case of Registered
Notes) the Certificate representing such Note(s) with the Registrar or any
Transfer Agent at its specified office, on a day which is a Business Day in the
City of London and in the place of such specified office falling within the
period (the "Put Period") of 45 days after that on which a Put Event Notice is
given, accompanied by a duly completed and signed notice of exercise in the form
(for the time being current) obtainable from any specified office of any Paying
Agent, the Registrar or any Transfer Agent (as applicable) (a "Put Notice") and
in which the holder may specify a bank account to which payment is to be made
under this Condition 6. Where any Bearer Note is delivered without all Coupons
relating to it which mature after the day (the "Put Date") being the fifteenth
day after the date of expiry of the Put Period, the exercise of the Put Option
in respect of such Note shall be subject

                                      52
<PAGE>

to the provision of such indemnity as the Issuer may reasonably require. The
Paying Agent to which such Note and Put Notice or, as the case may be, the
Registrar or Transfer Agent to which the Certificate and Put Notice are
delivered shall issue to the Noteholder concerned a non-transferable receipt in
respect of the Note so delivered. Payment in respect of any Note so delivered
shall be made, if the holder duly specifies in the Put Notice an account with a
bank to which payment is to be made, on the Put Date by transfer to that bank
account and, in every other case, on or after the Put Date in each case against
presentation and surrender or (as the case may be) endorsement of such receipt
at any specified office of any Paying Agent. A Put Notice, once given, shall be
irrevocable. For the purposes of Conditions 9, 10, 11, 12, 14, 16 and 17 and for
certain other purposes specified in the Trust Deed, receipts issued pursuant to
this Condition 6(f) shall be treated as if they were Notes. The Issuer shall
redeem or, at the option of the Issuer, purchase (or procure the purchase of)
the relevant Note on the applicable Put Date unless previously redeemed or
purchased.

A Rating Downgrade or a Negative Rating Event or a non-investment grade rating
shall be deemed not to have occurred as a result or in respect of a
Restructuring Event if the Rating Agency making the relevant reduction in rating
or, where applicable, declining to assign a rating of at least investment grade
as provided in this Condition 6(f) does not announce or publicly confirm or
inform the Trustee in writing at its request that the reduction or, where
applicable, declining to assign a rating of at least investment grade was the
result, in whole or in part, of any event or circumstance comprised in or
arising as a result of the applicable Restructuring Event.

The Trust Deed provides that the Trustee is under no obligation to ascertain
whether a Restructuring Event, a Negative Rating Event or any event which could
lead to the occurrence of, or could constitute a, Restructuring Event has
occurred and until it shall have actual knowledge or express notice pursuant to
the Trust Deed to the contrary the Trustee may assume that no Restructuring
Event, Negative Rating Event or such other event has occurred. The Trust Deed
also provides that in determining whether or not a Restructuring Event has
occurred, the Trustee may rely solely on an opinion given in a certificate
signed by two directors of the Issuer.

on, or, at the option of the holder, by transfer to an account denominated in
that currency with, a bank in the principal financial centre for that currency;
provided that (i) in the case of ECU, the transfer may be to, or the cheque
drawn on, an ECU account with a bank in London, Luxembourg, Paris, Frankfurt or

Paying Agent in New York City in the same manner as aforesaid if (i) the Issuer

States

                                      58

payment in full of such amounts at all such offices is illegal or effectively
precluded by exchange controls or other similar restrictions on payment or
receipt of such amounts and (iii) such payment is then permitted by United
States law, without involving, in the opinion of the Issuer, any adverse tax
consequence to the Issuer.

(4) Payments Subject to Fiscal Laws

regulations and directives, but without prejudice to the provisions of Condition
8. No commission or expenses shall be charged to the Noteholders or
Couponholders in respect of such payments.

The Issuing and Paying Agent, the Paying Agents, the Registrar, the Transfer
Agents and the Calculation Agent initially appointed by the Issuer and their
respective specified offices are listed below. The Issuing and Paying Agent, the
Paying Agents, the Registrar, the Transfer Agents and the Calculation Agent act
solely as agents of the Issuer and do not assume any obligation or relationship
of agency or trust for or with any Noteholder or Couponholder. The Issuer
reserves the right at any time with the approval of the Trustee to vary or
terminate the appointment of the Issuing and Paying Agent, any other Paying
Agent, the Registrar, any Transfer Agent or the Calculation Agent and to appoint
additional or other Paying Agents or Transfer Agents, provided that the Issuer
shall at all times maintain (i) an Issuing and Paying Agent, (ii) a Registrar in
relation to Registered Notes, (iii) a Transfer Agent in relation to Registered
Notes, (iv) one or more Calculation Agent(s) where the Conditions so require,
(v) Paying Agents having specified offices in at least two major European cities
(including London) so long as the Notes are listed on the London Stock Exchange
and (vi) such other agents as may be required by any other stock exchange on
which the Notes may be listed, in each case, as approved by the Trustee.

In addition, the Issuer shall forthwith appoint a Paying Agent in New York City
in respect of any Bearer Notes denominated in U.S. dollars in the circumstances
described in paragraph (c) above.

Notice of any such change or any change of any specified office shall promptly
be given to the Noteholders.

(f) Unmatured Coupons and Receipts and Unexchanged Talons

(i) Unless the Pricing Supplement provides that the relative Coupons are to
become void upon the due date for redemption of those Notes, Bearer Notes should
be surrendered for payment together with all unmatured Coupons (if any)
appertaining thereto, failing which an amount equal to the face value of each
missing unmatured Coupon (or, in the case of payment not being made in full,
that proportion of the amount of such missing unmatured Coupon that the sum of
principal so paid bears to the total principal due) shall be deducted from the
Redemption Amount due for payment. Any amount so deducted shall be paid in the
manner mentioned above against surrender of such missing Coupon within a period
of 10 years from the Relevant Date for the payment of such principal (whether or
not such Coupon has become void pursuant to Condition 9).

(ii) If the Pricing Supplement so provides, upon the due date for redemption of
any Bearer Note, unmatured Coupons relating to such Note (whether or not
attached) shall become void and no payment shall be made in respect of them.

(iii) Upon the due date for redemption of any Bearer Note, any unexchanged Talon
relating to such Note (whether or not attached) shall become void and no Coupon
shall be delivered in respect of such Talon.

(iv) Upon the due date for redemption of any Bearer Note that is redeemable in
instalments, all Receipts relating to such Note having an Instalment Date
falling on or after such due date (whether or not attached) shall become void
and no payment shall be made in respect of them.

(v) Where any Bearer Note that provides that the relative unmatured Coupons are
to become void upon the due date for redemption of those Notes is presented for
redemption without all unmatured Coupons and any unexchanged Talon relating to
it, and where any Bearer Note is presented for redemption without all unmatured
Coupons and any unexchanged Talon relating to it, redemption shall be made only
against the provision of such indemnity as the Issuer may require.

                                      59
<PAGE>

(vi) If the due date for redemption of any Note is not a due date for payment of
interest, interest accrued from the preceding due date for payment of interest
or the Interest Commencement Date, as the case may be, shall only be payable
against presentation (and surrender if appropriate) of the relevant Bearer Note
or Certificate representing it, as the case may be. Interest accrued on a Note
that only bears interest after its Maturity Date shall be payable on redemption
of such Note against presentation of the relevant Note or Certificate
representing it, as the case may be.

(g) Talons

On or after the Interest Payment Date for the final Coupon forming part of a
Coupon sheet issued in respect of any Bearer Note, the Talon forming part of
such Coupon sheet may be surrendered at the specified office of the Issuing and
Paying Agent in exchange for a further Coupon sheet (and if necessary another
Talon for a further Coupon sheet) (but excluding any Coupons that may have
become void pursuant to Condition 9).

(h) Non-Business Days

If any date for payment in respect of any Note, Receipt or Coupon is not a
business day, the holder shall not be entitled to payment until the next
following business day nor to any interest or other sum in respect of such
postponed payment. In this paragraph, "business day" means a day (other than a
Saturday or a Sunday) on which banks and foreign exchange markets are open for
business in the relevant place of presentation, in such jurisdictions as shall
be specified as "Business Day Jurisdictions" hereon and:

(i) (in the case of a payment in a currency other than ECU) where payment is to
be made by transfer to an account maintained with a bank in the relevant
currency, on which foreign exchange transactions may be carried on in the
relevant currency in the principal financial centre of the country of such
currency or

(ii) (in the case of a payment in ECU) on which banks are open for business and
carrying out transactions in ECU in the jurisdiction in which the ECU account
specified by the payee is located.

(i) ECU Notes

(i) Definition of the ECU

The ECU for the purpose of any Notes denominated or payable in ECU ("ECU") is
the same as the ECU that is from time to time used as the unit of account of the
EC. Changes to the ECU may be made by the EC, in which event the ECU shall
change accordingly.

(ii) Choice of Component Currencies for Future Payments

With respect to each due date for the payment of principal, interest or other
amounts in respect of Notes denominated in ECU on which the ECU is neither used
as the unit of account of the EC nor used as the currency of the European Union,
the Trustee shall, without liability on its part and without having regard to
the interests of individual Noteholders, choose a component currency of the ECU
(the "chosen currency") in which all payments due on that due date with respect
to such Notes shall be made. Notice of the chosen currency selected by the
Trustee shall, where practicable, be given to Noteholders. The amount of each
payment in the chosen currency shall be computed on the basis of the equivalent
of the ECU in that currency, determined as set out in this Condition 7(i) as of
the fourth Business Day in Luxembourg prior to the date on which such payment is
due.

(iii) Choice of Component Currency for Payments Already Due

On the first Business Day in Luxembourg on which the ECU is neither used as the
unit of account of the EC nor used as the currency of the European Union, the
Trustee shall, without liability on its part and without having regard to the
interests of individual Noteholders, choose a component currency of the ECU (the
"chosen currency") in which all payments of principal, interest or other amounts
in respect of Notes denominated in ECU having a due date prior thereto but not
yet presented for payment are to be made. The amount of each payment in the
chosen currency shall be computed on the basis of the equivalent of the ECU in
that currency, determined as set out in this Condition 7(i), as of such first
Business Day.

(iv) Determination of Equivalent in Component Currency

The equivalent of the ECU in the relevant chosen currency as of any date (the
"Day of Valuation") shall be determined on the following basis by a leading bank
(the "Computation Agent") having its head office in Europe appointed by the
Issuer and approved by the Trustee and notice of whose appointment is given to
Noteholders. The component currencies of the ECU for this purpose (the
"Components") shall be the currency amounts that were components of the ECU when
the ECU was most recently used as the unit of account of the EC. The equivalent
of the ECU in the chosen currency shall be calculated by, first,

                                      60
<PAGE>

aggregating the U.S. dollar equivalents of the Components, and then, using the
rate used for determining the U.S. dollar equivalent of the Component in the
chosen currency as set out below, calculating the equivalent in the chosen
currency of such aggregate amount in U.S. dollars.

(v) U.S. dollar Equivalent of Component Currencies

The U.S. dollar equivalent of each of the Components shall be determined by the
Computation Agent on the basis of the middle spot delivery quotations prevailing
at 2.30 p.m. (Luxembourg time) on the Day of Valuation, as obtained by the
Computation Agent from one or more leading banks, as selected by the Trustee or
the Computation Agent, in the country of issue of the Component in question.

(vi) No Direct Quotation for Component Currency

If no direct quotations are available for a Component as of a Day of Valuation
from any of the banks selected by the Trustee or the Computation Agent for this
purpose because foreign exchange markets are closed in the country of issue of
that currency or for any other reason, the most recent direct quotations for
that currency obtained by the Computation Agent shall be used in computing the
equivalents of the ECU on such Day of Valuation, provided, however, that such
most recent quotations may be used only if they were prevailing in the country
of issue not more than two Business Days for such currency before such Day of
Valuation. Beyond such period of two Business Days for such currency, the
Computation Agent shall determine the U.S. dollar equivalent of such Component
on the basis of cross rates derived from the middle spot delivery quotations for
such component currency and for the U.S. dollar prevailing at 2.30 p.m.
(Luxembourg time) on such Day of Valuation, as obtained by the Computation Agent
from one or more leading banks, as selected by the Computation Agent, in a
country other than the country of issue of such Component. Within such period of
two Business Days for such currency, the Computation Agent shall determine the
U.S. dollar equivalent of such Component on the basis of such cross rates if the
Computation Agent judges that the equivalent so calculated is more
representative than the U.S. dollar equivalent calculated on the basis of such
most recent direct quotations. Unless otherwise specified by the Computation
Agent, if there is more than one market for dealing in any Component by reason
of foreign exchange regulations or for any other reason, the market to be
referred to in respect of such currency shall be that upon which a non-resident
issuer of securities denominated in such currency would purchase such currency
in order to make payments in respect of such securities.

(vii) Determinations made by the Computation Agent or the Trustee

All determinations made by the Computation Agent or the Trustee shall be at
their sole discretion and shall, in the absence of manifest error, be conclusive
for all purposes and binding on the Issuer and all Noteholders and
Couponholders.

8. Taxation

All payments of principal and interest in respect of the Notes, the Receipts and
the Coupons (other than payments of interest in respect of Registered Notes
which will be made subject to the deduction of any United Kingdom income tax
required to be withheld or deducted at source) shall be made free and clear of,
and without withholding or deduction for, any taxes, duties, assessments or
governmental charges of whatever nature imposed, levied, collected, withheld or
assessed by or within the United Kingdom or any authority therein or thereof
having power to tax, unless such withholding or deduction is required by law. In
that event, the Issuer shall pay such additional amounts as shall result in
receipt by the Noteholders and Couponholders of such amounts as would have been
received by them had no such withholding or deduction been required, except that
no such additional amounts shall be payable with respect to any Note, Receipt or
Coupon:

(a) to, or to a third party on behalf of, a holder who is liable to such taxes,
duties, assessments or governmental charges in respect of such Note, Receipt or
Coupon by reason of his having some connection with the United Kingdom other
than the mere holding of the Note, Receipt or Coupon; or

(b) presented (or in respect of which the Certificate representing it is
presented) for payment more than 30 days after the Relevant Date except to the
extent that the holder of it would have been entitled to such additional amounts
on presenting it for payment on the thirtieth day; or

(c) presented for payment in the United Kingdom.*

As used in these Conditions, "Relevant Date" in respect of any Note, Receipt or
Coupon means the date on which payment in respect of it first becomes due or (if
any amount of the money payable is improperly withheld or refused) the date on
which payment in full of the amount outstanding is made or (if earlier) the date
seven days after that on which notice is duly given to the Noteholders that,
upon further presentation of the Note (or relative Certificate), Receipt or
Coupon being made in accordance with the Conditions, such payment will be made,
provided that payment is in fact made upon such presentation. References in
these

                                      61
<PAGE>

Conditions to (i) "principal" shall be deemed to include any premium payable in
respect of the Notes, all Instalment Amounts, Redemption Amounts, Amortised Face
Amounts and all other amounts in the nature of principal payable pursuant to
Condition 6 or any amendment or supplement to it, (ii) "interest" shall be
deemed to include all Interest Amounts and all other amounts payable pursuant to
Condition 5 or any amendment or supplement to it and (iii) "principal" and/or
"interest" shall be deemed to include any additional amounts that may be payable
under this Condition or any undertaking given in addition to or in substitution
for it under the Trust Deed.

9. Prescription

Claims against the Issuer for payment in respect of the Notes, Receipts and
Coupons (which, for this purpose, shall not include Talons) shall be prescribed
and become void unless made within 10 years (in the case of principal) or five
years (in the case of interest) from the appropriate Relevant Date in respect of
them.

10. Events of Default

The Trustee at its discretion may, and if so requested in writing by the holders
of at least one-quarter in principal amount of the Notes then outstanding or if
so directed by an Extraordinary Resolution of the Noteholders shall, subject to
being indemnified to its satisfaction, (but, in the case of the happening of any
of the events mentioned in sub-paragraphs (b), (c), (e), (f), (g) and (h) below,
only if the Trustee shall have certified in writing to the Issuer that such
event is, in its opinion, materially prejudicial to the interests of the
Noteholders), give notice to the Issuer that the Notes are, and they shall
accordingly thereby forthwith become, immediately due and repayable at their
principal amount together with accrued interest (as provided in the Trust Deed)
if any of the following events (each an "Event of Default") shall have occurred
(unless such Event of Default has been remedied to the satisfaction of the
Trustee):

(a) if default is made for a period of 14 days or more in the payment of any
principal or the purchase price due in respect of any Notes pursuant to
Condition 6 or 21 days or more in the payment of any interest due in respect of
the Notes or any of them; or

(b) if the Issuer fails to perform or observe any of its other obligations under
the Notes or the Trust Deed and (except where the Trustee shall have certified
to the Issuer in writing that it considers such failure to be incapable of
remedy in which case no such notice or continuation as is hereinafter mentioned
will be required) such failure continues for the period of 60 days (or such
longer period as the Trustee may in its absolute discretion permit) next
following the service by the Trustee of notice on the Issuer requiring the same
to be remedied; or

(c) if (i) any other indebtedness for borrowed money of the Issuer or any
Principal Subsidiary becomes due and repayable prior to its stated maturity by
reason of an event of default or (ii) any such indebtedness for borrowed money
is not paid when due or, as the case may be, within any applicable grace period
(as originally provided) or (iii) the Issuer or any Principal Subsidiary fails
to pay when due (or, as the case may be, within any originally applicable grace
period) any amount payable by it under any present or future guarantee for, or
indemnity in respect of, any indebtedness for borrowed money of any person or
(iv) any security given by the Issuer or any Principal Subsidiary for any
indebtedness for borrowed money of any person or for any guarantee or indemnity
of indebtedness for borrowed money of any person becomes enforceable by reason
of default in relation thereto and steps are taken to enforce such security,
save in any such case where there is a bona fide dispute as to whether the
relevant indebtedness for borrowed money or any such guarantee or indemnity as
aforesaid shall be due and payable, provided that the aggregate amount of the
relevant indebtedness for borrowed money in respect of which any one or more of
the events mentioned above in this sub-paragraph (c) has or have occurred equals
or exceeds whichever is the greater of (pound)20,000,000 or its equivalent in
other currencies (as determined by the Trustee) or 2% of Capital and Reserves,
and for the purposes of this sub-paragraph (c), "indebtedness for borrowed
money" shall exclude Project Finance Indebtedness; or

(d) if any order shall be made by any competent court or any resolution shall be
passed for the winding up or dissolution of the Issuer, save for the purpose of
amalgamation, merger, consolidation, reorganisation, reconstruction or other
similar arrangement on terms previously approved in writing by the Trustee (such
approval not to be unreasonably withheld or delayed having regard to the
interests of the Noteholders) or by an Extraordinary Resolution of the
Noteholders; or

(e) if (i) any order shall be made by any competent court or any resolution
shall be passed for the winding up or dissolution of a Principal Subsidiary,
save for the purposes of amalgamation, merger, consolidation,

                                      62
<PAGE>

reorganisation, reconstruction or other similar arrangement (A) not involving or
arising out of the insolvency of such Principal Subsidiary and under which all
the surplus assets of such Principal Subsidiary are transferred to the Issuer or
any of its other Subsidiaries (other than an Excluded Subsidiary) or (B) the
terms of which have previously been approved in writing by the Trustee (such
approval not to be unreasonably withheld or delayed having regard to the
interests of Noteholders) or by an Extraordinary Resolution of the Noteholders
or (ii) a petition is presented under Section 24 of the Water Industry Act (and
is not dismissed within 60 days) or a special administration order is made under
Section 24 of the Water Industry Act in respect of SWSL; or

(f) if the Issuer or any Principal Subsidiary shall cease to carry on the whole
or substantially the whole of its business, save in each case for the purposes
of amalgamation, merger, consolidation, reorganisation, reconstruction, or other
similar arrangement (i) not involving or arising out of the insolvency of the
Issuer or such Principal Subsidiary and under which all or substantially all of
its assets are transferred to another member or members of the Group (other than
an Excluded Subsidiary) or to a transferee or transferees which is or are, or
immediately upon such transfer become(s), a Principal Subsidiary or Principal
Subsidiaries, or (ii) under which all or substantially all of its assets are
transferred to a third party or parties (whether associates or not) for full
consideration by the Issuer or a Principal Subsidiary on an arm's length basis
or (iii) the terms of which have previously been approved in writing by the
Trustee or by an Extraordinary Resolution of the Bondholders, provided that if
neither the Issuer nor any Relevant Subsidiary holds an Electricity Licence, the
Issuer shall be deemed to have ceased to carry on the whole or substantially the
whole of its business (and neither of exceptions (i) and (ii) shall apply); or

(g) if the Issuer or any Principal Subsidiary shall suspend or announce its
intention to suspend payment of its debts generally or shall be declared or
adjudicated by a competent court to be unable, or shall admit in writing its
inability, to pay its debts generally (within the meaning of Section 123(1) or
(2) of the Insolvency Act 1986) as they fall due, or shall be adjudicated or
found insolvent by a competent court or shall enter into any composition or
other similar arrangement with its creditors generally under Section 1 of the
Insolvency Act 1986; or

(h) if a receiver, administrative receiver, administrator or other similar
official shall be appointed in relation to the Issuer or any Principal
Subsidiary or in relation to the whole or a substantial part of the undertaking
or assets of any of them or a distress, execution or other process shall be
levied or enforced upon or sued out against, or any encumbrancer shall take
possession of, the whole or a substantial part of the assets of any of them and
in any of the foregoing cases it or he shall not be paid out or discharged
within 90 days (or such longer period as the Trustee may in its absolute
discretion permit).

For the purposes of sub-paragraph (g) above, Section 123(1)(a) of the Insolvency
Act 1986 shall have effect as if for "(pound)750" there was substituted
"(pound)250,000". Neither the Issuer nor any Principal Subsidiary shall be
deemed to be unable to pay its debts for the purposes of sub-paragraph (g) above
if any such demand as is mentioned in Section 123(1)(a) of the Insolvency Act
1986 is being contested in good faith by the Issuer or the relevant Principal
Subsidiary with recourse to all appropriate measures and procedures or if any
such demand is satisfied before the expiration of such period as may be stated
in any notice given by the Trustee under this Condition.

11. Meetings of Noteholders, Modification, Waiver and Substitution

(a) Meetings of Noteholders

The Trust Deed contains provisions for convening meetings of Noteholders to
consider matters affecting their interests, including the modification of any of
the terms and conditions of the Notes or any provisions of the Trust Deed. Any
such modification may be made if sanctioned by an Extraordinary Resolution. The
quorum for any meeting convened to consider an Extraordinary Resolution will be
one or more persons holding or representing a clear majority in principal amount
of the Notes for the time being outstanding, or at any adjourned meeting, one or
more persons being or representing Noteholders whatever the principal amount of
the Notes held or represented, unless the business of such meeting includes
consideration of proposals, inter alia (i) to postpone the maturity or
redemption of the Notes, any Instalment Date or any date for payment of any
interest or Interest Amount on the Notes, (ii) to reduce or cancel the principal
amount of, or any Instalment Amount of, or any premium payable on redemption of,
the Notes, (iii) to reduce the rate or rates of interest in respect of the Notes
or to vary the method or basis of calculating the rate or rates or amount of
interest or the basis for calculating any Interest Amount in respect of the
Notes, (iv) if a Minimum and/or a Maximum Interest Rate, Instalment Amount or
Redemption Amount is shown hereon, to reduce any such Minimum and/or Maximum,
(v) to vary any method of, or basis for, calculating the Redemption Amount,
including the method of calculating the Amortised Face Amount, (vi) to vary the
currency or currencies of payment or denomination of the Notes, (vii) to take
any steps that as specified hereon may only be taken following approval by an
Extraordinary Resolution to which the special quorum provisions apply, or (viii)
to modify the provisions concerning the quorum required at any meeting of
Noteholders or the majority required to pass the Extraordinary Resolution, in
which case the necessary

                                      63
<PAGE>

quorum shall be one or more persons holding or representing not less than
two-thirds, or at any adjourned meeting not less than one-third, in principal
amount of the Notes for the time being outstanding. Any Extraordinary Resolution
duly passed shall be binding on Noteholders (whether or not they were present at
the meeting at which such resolution was passed) and on all Couponholders.

These Conditions may be amended, modified or varied in relation to any Series of
Notes by the terms of the relevant Pricing Supplement in relation to such
Series.

(b) Modification of the Trust Deed

The Trustee may agree, without the consent of the Noteholders or Couponholders,
to (i) any modification of any of the provisions of the Trust Deed, the Notes or
the Coupons that is of a formal, minor or technical nature or is made to correct
a manifest error, and (ii) any other modification (except as mentioned in the
Trust Deed), and any waiver or authorisation of any breach or proposed breach,
of any of the provisions of the Trust Deed that is in the opinion of the Trustee
not materially prejudicial to the interests of the Noteholders. Any such
modification, authorisation or waiver shall be binding on the Noteholders and
the Couponholders and, if the Trustee so requires, such modification shall be
notified to the Noteholders as soon as practicable.

(c) Substitution

The Trust Deed contains provisions permitting the Trustee to agree, subject to
such amendment of the Trust Deed and such other conditions as the Trustee may
require, but without the consent of the Noteholders or the Couponholders, to the
substitution of any other company in place of the Issuer, or of any previous
substituted company, as principal debtor under the Trust Deed and the Notes. In
the case of such a substitution the Trustee may agree, without the consent of
the Noteholders or the Couponholders, to a change of the law governing the
Notes, the Receipts, the Coupons, the Talons and/or the Trust Deed provided that
such change would not in the opinion of the Trustee be materially prejudicial to
the interests of the Noteholders.

(d) Entitlement of the Trustee

In connection with the exercise of its functions (including but not limited to
those referred to in this Condition) the Trustee shall have regard to the
interests of the Noteholders as a class and shall not have regard to the
consequences of such exercise for individual Noteholders or Couponholders and
the Trustee shall not be entitled to require, nor shall any Noteholder or
Couponholder be entitled to claim, from the Issuer any indemnification or
payment in respect of any tax consequence of any such exercise upon individual
Noteholders or Couponholders.

12. Replacement of Notes, Certificates, Receipts, Coupons and Talons

If a Note, Certificate, Receipt, Coupon or Talon is lost, stolen, mutilated,
defaced or destroyed, it may be replaced, subject to applicable laws,
regulations and stock exchange regulations, at the specified office of the
Issuing and Paying Agent (in the case of Bearer Notes, Receipts, Coupons or
Talons) and of the Registrar (in the case of Certificates) or such other Paying
Agent or Transfer Agent, as the case may be, as may from time to time be
designated by the Issuer for the purpose and notice of whose designation is
given to Noteholders, in each case on payment by the claimant of the fees and
costs incurred in connection therewith and on such terms as to evidence,
security and indemnity (which may provide, inter alia, that if the allegedly
lost, stolen or destroyed Note, Certificate, Receipt, Coupon or Talon is
subsequently presented for payment or, as the case may be, for exchange for
further Coupons, there shall be paid to the Issuer on demand the amount payable
by the Issuer in respect of such Notes, Certificates, Receipts, Coupons or
further Coupons) and otherwise as the Issuer may reasonably require. Mutilated
or defaced Notes, Certificates, Receipts, Coupons or Talons must be surrendered
before replacements will be issued.

13. Further Issues

The Issuer may from time to time without the consent of the Noteholders or
Couponholders create and issue further securities either having the same terms
and conditions as the Notes in all respects (or in all respects except for the
first payment of interest on them) and so that such further issue shall be
consolidated and form a single series with the outstanding securities of any
series (including the Notes) or upon such terms as the Issuer may determine at
the time of their issue. References in these Conditions to the Notes include
(unless the context requires otherwise) any other securities issued pursuant to
this Condition and forming a single series with the Notes. Any further
securities forming a single series with the outstanding securities of any series
(including the Notes) constituted by the Trust Deed or any deed supplemental to
it shall, and any other securities may (with the consent of the Trustee), be
constituted by the Trust Deed. The Trust Deed contains provisions for convening
a single meeting of the Noteholders and the holders of securities of other
series where the Trustee so decides.

                                      64
<PAGE>

14. Enforcement

At any time after the Notes become due and payable, the Trustee may, as its
discretion and without further notice, institute such proceedings against the
Issuer as it may think fit to enforce the terms of the Trust Deed, but it need
not take any such proceedings unless (a) it shall have been so directed by an
Extraordinary Resolution or so requested in writing by holders of at least
one-fifth in principal amount of the Notes outstanding, and (b) it shall have
been indemnified to its satisfaction. No Noteholder, Receiptholder or
Couponholder may proceed directly against the Issuer unless the Trustee, having
become bound so to proceed fails to do so within a reasonable time and such
failure is continuing.

15. Indemnification of the Trustee

The Trust Deed contains provisions for the indemnification of the Trustee and
for its relief from responsibility. The Trustee is entitled to enter into
business transactions with the Issuer and any entity related to the Issuer
without accounting for any profit.

16. Notices

Notices to the holders of Registered Notes shall be mailed to them at their
respective addresses in the Register and deemed to have been given on the fourth
weekday (being a day other than a Saturday or a Sunday) after the date of
mailing. Notices to the holders of Bearer Notes shall be valid if published in a
daily newspaper of general circulation in London (which is expected to be the
Financial Times). The Issuer shall also ensure that notices are duly published
in a manner which complies with the rules and regulations of any other stock
exchange on which the Notes are, for the time being, listed. Any such notice
shall be deemed to have been given on the date of such publication or, if
published more than once or on different dates, on the first date on which
publication is made, as provided above.

Couponholders shall be deemed for all purposes to have notice of the contents of
any notice given to the holders of Bearer Notes in accordance with this
Condition.

17. Governing Law and Jurisdiction

(a) Governing Law

The Trust Deed, the Notes, the Receipts, the Coupons and the Talons are governed
by, and shall be construed in accordance with, English law.

(b) Jurisdiction

The courts of England are to have jurisdiction to settle any disputes that may
ate out of or in connection with any Notes, Receipts, Coupons or Talons and
accordingly any legal action or proceedings arising out of or in connection with
any Notes, Receipts, Coupons or Talons ("Proceedings") may be brought in such
courts. The Issuer has in the Trust Deed irrevocably submitted to the
jurisdiction of such courts.

(c) Service of Process

The Issuer, in accordance with the Trust Deed, will appoint its London office,
whose address is at 54 Queen Anne Street, London W1M 9LA to act as its agent in
England to receive, for it and on its behalf, service of process in any
Proceedings in England.

                                   SCHEDULE 3
                     Provisions for Meetings of Noteholders

      Interpretation

      of Notes and include, unless the context otherwise requires, any
      adjournment

1.2   references to "Notes" and "Noteholders" are only to the Notes of the
      Series in respect of which a meeting has been, or is to be, called, and to
      the holders of these Notes, respectively

1.3   "agent" means a holder of a voting certificate or a proxy for, or
      representative of, a Noteholder

1.4   "block voting instruction" means an instruction issued in accordance with
      paragraphs 8 to 14

1.5   "Extraordinary Resolution" means a resolution passed at a meeting duly
      convened and held in accordance with this Trust Deed by a majority of at
      least 75 per cent of the votes cast

1.6   "voting certificate" means a certificate issued in accordance with
      paragraphs 5, 6, 7 and 14 and

1.7   references to persons representing a proportion of the Notes are to
      Noteholders or agents holding or representing in the aggregate at least
      that proportion in principal amount of the Notes for the time being
      outstanding.

      Powers of meetings

2     A meeting shall, subject to the Conditions and without prejudice to any
      powers conferred on other persons by this Trust Deed, have power by
      Extraordinary Resolution:

2.1   to sanction any proposal by the Issuer or the Trustee for any
      modification, abrogation, variation or compromise of, or arrangement in
      respect of, the rights of the Noteholders and/or the Couponholders against
      the Issuer, whether or not those rights arise under this Trust Deed

2.2   to sanction the exchange or substitution for the Notes of, or the
      conversion of the Notes into, shares, bonds or other obligations or
      securities of the Issuer or any other entity

2.3   to assent to any modification of this Trust Deed, the Notes, the Receipts,

2.5   to give any authority, direction or sanction required to be given by

2.7   to approve a proposed new Trustee and to remove a Trustee

2.8   to approve the substitution of any entity for the Issuer (or any previous
      substitute) as principal debtor or guarantor under this Trust Deed and


- --------------------------------------------------------------------------------
                                       71
<PAGE>

2.9   to discharge or exonerate the Trustee from any liability in respect of any
      act or omission for which it may become responsible under this Trust Deed,
      the Notes, the Receipts, the Talons or the Coupons

      provided that the special quorum provisions in paragraph 19 shall apply to
      any Extraordinary Resolution (a "special quorum resolution") for the
      purpose of sub-paragraph 2.2 or 2.8, any of the proposals listed in
      Condition 11(a) or any amendment to this proviso.

      Convening a meeting

3     The Issuer or the Trustee may at any time convene a meeting. If it
      receives a written request by Noteholders holding at least 10 per cent in
      principal amount of the Notes of any Series for the time being outstanding
      and is indemnified to its satisfaction against all costs and expenses, the
      Trustee shall convene a meeting of the Noteholders of that Series. Every
      meeting shall be held at a time and place approved by the Trustee.

4     At least 21 days' notice (exclusive of the day on which the notice is
      given and of the day of the meeting) shall be given to the Noteholders. A
      copy of the notice shall be given by the party convening the meeting to
      the other parties. The notice shall specify the day, time and place of
      meeting and, unless the Trustee otherwise agrees, the nature of the
      resolutions to be proposed and shall explain how Noteholders may appoint
      proxies or representatives, obtain voting certificates and use block
      voting instructions and the details of the time limits applicable.

      Arrangements for voting

5     If a holder of a Bearer Note wishes to obtain a voting certificate in
      respect of it for a meeting, he must deposit it for that purpose at least
      48 hours before the time fixed for the meeting with a Paying Agent or to
      the order of a Paying Agent with a bank or other depositary nominated by
      the Paying Agent for the purpose. The Paying Agent shall then issue a
      voting certificate in respect of it.

6     A voting certificate shall:

6.1   be a document in the English language

6.2   be dated

6.3   specify the meeting concerned and the serial numbers of the Notes
      deposited and

6.4   entitle, and state that it entitles, its bearer to attend and vote at that
      meeting in respect of those Notes.

7     Once a Paying Agent has issued a voting certificate for a meeting in
      respect of a Note, it shall not release the Note until either:

7.1   the meeting has been concluded or

7.2   the voting certificate has been surrendered to the Paying Agent.

8     If a holder of a Bearer Note wishes the votes attributable to it to be
      included in a block voting instruction for a meeting, then, at least 48
      hours before the time fixed for the meeting, (i) he must deposit the Note
      for that purpose with a Paying Agent or to the order of a Paying Agent
      with a bank or other depositary nominated by the Paying Agent for the
      purpose and (ii) he or a duly authorised person on his behalf must direct
      the Paying Agent how those votes are to be cast. The Paying Agent shall
      issue a block voting instruction in respect of the votes attributable to
      all Notes so deposited.


- --------------------------------------------------------------------------------
                                       72
<PAGE>

9     A block voting instruction shall:

9.1   be a document in the English language

9.2   be dated

9.3   specify the meeting concerned

9.4   list the total number and serial numbers of the Notes deposited,
      distinguishing with regard to each resolution between those voting for and
      those voting against it

9.5   certify that such list is in accordance with Notes deposited and
      directions received as provided in paragraphs 8, 11 and 14 and

9.6   appoint a named person (a "proxy") to vote at that meeting in respect of
      those Notes and in accordance with that list.

      A proxy need not be a Noteholder.

10    Once a Paying Agent has issued a block voting instruction for a meeting in
      respect of the votes attributable to any Notes:

10.1  it shall not release the Notes, except as provided in paragraph 11, until
      the meeting has been concluded and

10.2  the directions to which it gives effect may not be revoked or altered
      during the 48 hours before the time fixed for the meeting.

11    If the receipt for a Note deposited with a Paying Agent in accordance with
      paragraph 8 is surrendered to the Paying Agent at least 48 hours before
      the time fixed for the meeting, the Paying Agent shall release the Note
      and exclude the votes attributable to it from the block voting
      instruction.

12    Each block voting instruction shall be deposited at least 24 hours before
      the time fixed for the meeting at such place as the Trustee shall
      designate or approve, and in default it shall not be valid unless the
      chairman of the meeting decides otherwise before the meeting proceeds to
      business. If the Trustee requires, a notarially certified copy of each
      block voting instruction shall be produced by the proxy at the meeting but
      the Trustee need not investigate or be concerned with the validity of the
      proxy's appointment.

13    A vote cast in accordance with a block voting instruction shall be valid
      even if it or any of the Noteholders' instructions pursuant to which it
      was executed has previously been revoked or amended, unless written
      intimation of such revocation or amendment is received from the relevant
      Paying Agent by the Issuer or the Trustee at its registered office or by
      the chairman of the meeting in each case at least 24 hours before the time
      fixed for the meeting.

14    No Note may be deposited with or to the order of a Paying Agent at the
      same time for the purposes of both paragraph 5 and paragraph 8 for the
      same meeting.

15.1  A holder of a Registered Note may, by an instrument in writing in the form
      available from the specified office of a Transfer Agent in the English
      language executed by or on behalf of the holder and delivered to the
      Transfer Agent at least 24 hours before the time fixed for a meeting,
      appoint any person (a "proxy") to act on his behalf in connection with
      that meeting. A proxy need not be a Noteholder.

15.2  A corporation which holds a Registered Note may by delivering to a
      Transfer Agent at least 24 hours before the time fixed for a meeting a
      certified copy of a resolution of its directors or other

      governing body (with, if it is not in English, a certified translation
      into English) authorise any person to act as its representative (a
      "representative") in connection with that meeting.

      Chairman

16    The chairman of a meeting shall be such person as the Trustee may nominate
      in writing, but if no such nomination is made or if the person nominated
      is not present within 15 minutes after the time fixed for the meeting the
      Noteholders or agents present shall choose one of their number to be
      chairman, failing which the Issuer may appoint a chairman. The chairman
      need not be a Noteholder or agent. The chairman of an adjourned meeting
      need not be the same person as the chairman of the original meeting.

      Attendance

17    The following may attend and speak at a meeting:

17.1  Noteholders and agents

17.2  the chairman

17.3  the Issuer and the Trustee (through their respective representatives) and
      their respective financial and legal advisers

17.4  the Dealers and their advisers.

      No-one else may attend or speak.

      Quorum and Adjournment

18    No business (except choosing a chairman) shall be transacted at a meeting
      unless a quorum is present at the commencement of business. If a quorum is
      not present within 15 minutes from the time initially fixed for the
      meeting, it shall, if convened on the requisition of Noteholders or if the
      Issuer and the Trustee agree, be dissolved. In any other case it shall be
      adjourned until such date, not less than 14 nor more than 42 days later,
      and time and place as the chairman may decide. If a quorum is not present
      within 15 minutes from the time fixed for a meeting so adjourned, the
      meeting shall be dissolved.

19    One or more Noteholders or agents present in person shall be a quorum:

19.1  in the cases marked "No minimum proportion" in the table below, whatever
      the proportion of the Notes which they represent

19.2  in any other case, only if they represent the proportion of the Notes
      shown by the table below.

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

20    The chairman may with the consent of (and shall if directed by) a meeting
      adjourn the meeting from time to time and from place to place. Only
      business which could have been transacted at the original meeting may be
      transacted at a meeting adjourned in accordance with this paragraph or
      paragraph 18.

21    At least 10 days' notice of a meeting adjourned through want of a quorum
      shall be given in the same manner as for an original meeting and that
      notice shall state the quorum required at the adjourned meeting. No notice
      need, however, otherwise be given of an adjourned meeting.

      Voting

22    Each question submitted to a meeting shall be decided by a show of hands
      unless a poll is (before, or on the declaration of the result of, the show
      of hands) demanded by the chairman, the Issuer, the Trustee or one or more
      persons representing 2 per cent of the Notes.

23    Unless a poll is demanded a declaration by the chairman that a resolution
      has or has not been passed shall be conclusive evidence of the fact
      without proof of the number or proportion of the votes cast in favour of
      or against it.

24    If a poll is demanded, it shall be taken in such manner and (subject as
      provided below) either at once or after such adjournment as the chairman
      directs. The result of the poll shall be deemed to be the resolution of
      the meeting at which it was demanded as at the date it was taken. A demand
      for a poll shall not prevent the meeting continuing for the transaction of
      business other than the question on which it has been demanded.

25    A poll demanded on the election of a chairman or on a question of
      adjournment shall be taken at once.

26    On a show of hands every person who is present in person and who produces
      a Bearer Note, a Certificate of which he is the registered holder or a
      voting certificate or is a proxy or representative has one vote. On a poll
      every such person has one vote in respect of each principal amount equal
      to the minimum denomination of such Series of Notes so produced or
      represented by the voting certificate so produced or for which he is a
      proxy or representative. Without prejudice to the obligations of proxies,
      a person entitled to more than one vote need not use them all or cast them
      all in the same way.

27    In case of equality of votes the chairman shall both on a show of hands
      and on a poll have a casting vote in addition to any other votes which he
      may have.

      Effect and Publication of an Extraordinary Resolution

28    An Extraordinary Resolution shall be binding on all the Noteholders,
      whether or not present at the meeting, and on all the Couponholders and
      each of them shall be bound to give effect to it accordingly. The passing
      of such a resolution shall be conclusive evidence that the circumstances
      justify its being passed. The Issuer shall give notice of the passing of
      an


- --------------------------------------------------------------------------------
                                       75
<PAGE>

      Extraordinary Resolution to Noteholders within 14 days but failure to do
      so shall not invalidate the resolution.

      Minutes

29    Minutes shall be made of all resolutions and proceedings at every meeting
      and, if purporting to be signed by the chairman of that meeting or of the
      next succeeding meeting, shall be conclusive evidence of the matters in
      them. Until the contrary is proved every meeting for which minutes have
      been so made and signed shall be deemed to have been duly convened and
      held and all resolutions passed or proceedings transacted at it to have
      been duly passed and transacted.

      Trustee's Power to Prescribe Regulations

30    Subject to all other provisions in this Trust Deed the Trustee may without
      the consent of the Noteholders prescribe such further regulations
      regarding the holding of meetings and attendance and voting at them as it
      in its sole discretion determines including (without limitation) such
      requirements as the Trustee thinks reasonable to satisfy itself that the
      persons who purport to make any requisition in accordance with this Trust
      Deed are entitled to do so and as to the form of voting certificates or
      block voting instructions so as to satisfy itself that persons who purport
      to attend or vote at a meeting are entitled to do so.

31    The holder of a Global Note or Global Certificate shall (unless such
      Global Note or Global Certificate represents only one Note) be treated as
      2 persons for the purposes of any quorum requirements of a meeting of
      Noteholders.

32    The foregoing provisions of this Schedule shall have effect subject to the
      following provisions:

32.1  Meetings of Noteholders of separate Series will normally be held
      separately. However, the Trustee may from time to time determine that
      meetings of Noteholders of separate Series shall be held together

32.2  A resolution that in the opinion of the Trustee affects one Series alone
      shall be deemed to have been duly passed if passed at a separate meeting
      of the Noteholders of the Series concerned

32.3  A resolution that in the opinion of the Trustee affects the Noteholders of
      more than one Series but does not give rise to a conflict of interest
      between the Noteholders of the different Series concerned shall be deemed
      to have been duly passed if passed at a single meeting of the Noteholders
      of the relevant Series provided that for the purposes of determining the
      votes a Noteholder is entitled to cast pursuant to paragraph 26, each
      Noteholder shall have one vote in respect of each U.S.$1,000 principal
      amount of Notes held, converted, if such Notes are not denominated in U.S.
      dollars, in accordance with sub-Clause 8.12

32.4  A resolution that in the opinion of the Trustee affects the Noteholders of
      more than one Series and gives or may give rise to a conflict of interest
      between the Noteholders of the different Series concerned shall be deemed
      to have been duly passed only if it shall be duly passed at separate
      meetings of the Noteholders of the relevant Series

32.5  To all such meetings as aforesaid all the preceding provisions of this
      Schedule shall mutatis mutandis apply as though references therein to
      Notes and to Noteholders were references to the Notes and Noteholders of
      the Series concerned.

            U.S.$4,000,000,000 Debt Issuance Programme of the Issuers (the
            "Programme").

      (B)   The Issuer wishes to record that as a result of the sale by Morgan
            Guaranty Trust Company of New York of its Global Agency and Trust
            business to Citibank, N.A. on 26 June 1998 and by a letter of
            agreement dated 31 March 1998 between the Issuer, Morgan Guaranty
            Trust Company of New York, and Citibank, N.A., the Issuer (i)

            Notice to Noteholders and the Trustee as required by Clause 18.8 of
            the Agency Agreement was given in accordance with the Conditions on
            3 July 1998.

      (C)   The parties to this Supplemental Trust Deed wish to amend the Trust
            Deed as set out herein.

1     Definitions

      terms defined in the Trust Deed shall have the same meaning in this

2     Amendment

      of the power conferred on it by Clause 12.1 of the Trust Deed to modify
      the Trust Deed by amending the Trust Deed in the form of this Supplemental
      Trust Deed.

2.2   The Trust Deed, as amended by this Supplemental Trust Deed shall
      henceforward in relation to Notes issued on or after 6 November 1998 have
      effect as so amended. For the avoidance of doubt the Trust Deed shall
      continue to have effect in relation to Notes issues prior to 6 November
      1998. Subject thereto, references herein to the "Trust Deed" shall be to
      the Trust Deed as amended by this Supplemental Trust Deed.

5     Governing Law, Submission and Jurisdiction

5.1   Governing Law: This Supplemental Trust Deed shall be governed by and
      construed in accordance with English law.

5.2   Submission to Jurisdiction: The courts of England are to have jurisdiction
      to settle any disputes that may arise out of or in connection with this
      Supplemental Trust Deed, the Notes, the Receipts, the Coupons or the
      Talons and accordingly any legal action or proceedings arising out of or
      in connection with this Supplemental Trust Deed, the Notes, the Receipts,
      the Coupons or the Talons ("Proceedings") may be brought in such courts.
      The Issuer irrevocably submits to the jurisdiction of such courts and
      waives any objections to Proceedings in such courts on the ground of venue
      or on the ground that the Proceedings have been brought in an inconvenient
      forum. This submission is for the benefit of each of the Trustee, the
      Noteholders and the Couponholders and shall not limit the right of any of
      them to take Proceedings in any other court of competent jurisdiction nor
      shall the taking of Proceedings in any one or more jurisdictions preclude
      the taking of Proceedings in any other jurisdiction (whether concurrently
      or not).

5.3   Service of Process: The Issuer shall procure that its London office, whose
      address is at 54 Queen Anne Street, London W1M 9LA will act as its agent
      for service of process in any Proceedings in England. The Issuer
      undertakes that in the event of the agent of process appointed by it
      ceasing to so act, it will appoint such other person acceptable to the
      Trustee and shall immediately notify the Trustee of such appointment.
      Nothing shall affect the right to serve process in any other manner
      permitted by law.

an Exchangeable Bearer Note) Registered Notes represented by the Certificates
described below:

      (i)   by the Issuer giving notice to the Issuing and Paying Agent and the
            Noteholders of its intention to effect such exchange

      (ii)  if the Third Schedule hereto provides that this permanent Global
            Note is exchangeable for Definitive Notes at the request of the
            holder, by such holder giving notice to the Issuing and Paying Agent
            of its election for such exchange

      (iii) if this permanent Global Note is an Exchangeable Bearer Note, by the
            holder hereof giving notice to the Issuing and Paying Agent of its
            election to exchange the whole or a part of this permanent Global
            Note for Registered Notes or

      (iv)  otherwise, if this permanent Global Note is held on behalf of
            Euroclear or Cedel Bank or any other clearing system (an
            "Alternative Clearing System") and any such clearing system is
            closed for business for a continuous period of 14 days (other than
            by reason of holidays, statutory or otherwise) or announces an
            intention permanently to cease business or does in fact do so.

This permanent Global Note is exchangeable in part (provided, however, that if
this permanent Global Note is held by or on behalf of Euroclear and/or Cedel
Bank, the rules of Euroclear and/or Cedel Bank, as the case may be, so permit)
(i) if this permanent Global Note is an Exchangeable Bearer Note and the part
hereof submitted for exchange is to be exchanged for Registered Notes or (ii) if
so provided, and in accordance with, the Conditions relating to Partly-paid
Notes.

"Exchange Date" means a day falling not less than 60 days, or in the case of an
exchange for Registered Notes 5 days, after that on which the notice requiring
exchange is given and on which banks are open for business in the city in which
the specified office of the Issuing and Paying Agent is located and, except in
the case of exchange pursuant to (iv) above, in the cities in which Euroclear
and Cedel Bank or, if relevant, the Alternative Clearing System, are located.

Subject as provided in the Conditions applicable to Party-paid Notes, any such
exchange may be effected on or after an Exchange Date by the holder of this
permanent Global Note surrendering this permanent Global Note or, in the case of
a partial exchange, presenting it for endorsement to or to the order of the

thereof to be exchanged, the Issuer shall deliver, or procure the delivery of,
duly executed and authenticated Definitive Notes and/or (if this permanent
Global Note is an Exchangeable Bearer Note) Certificates in an aggregate
principal amount equal to the principal amount of this permanent Global Note
submitted for exchange (if appropriate, having attached to them all Coupons
(and, where appropriate, Talons) in respect of interest, and all Receipts in
respect of Instalment Amounts, that have not already been paid on this permanent
Global Note), security printed or, in the case of Certificates, printed in
accordance with any applicable legal and stock

exchange requirements and substantially in the form set out in Schedule 2 to the
Trust Deed as supplemented and/or modified and/or superseded by the terms of the
Third Schedule hereto. Certificates issued upon exchange for Registered Notes
shall not be Global Certificates unless the holder so requests and certifies to
the Issuing and Paying Agent that it is, or is acting as a nominee for, Cedel
Bank, Euroclear and/or an Alternative Clearing System.

On any exchange of a part of this permanent Global Note the portion of the
principal amount hereof so exchanged shall be endorsed by or on behalf of the
Issuing and Paying Agent in the First Schedule hereto, whereupon the principal
amount hereof shall be reduced for all purposes by the amount so exchanged and
endorsed.

Benefit of Conditions

Except as otherwise specified herein, this permanent Global Note is subject to
the Conditions and the Trust Deed and, until the whole of this permanent Global
Note is exchanged for Definitive Notes or Registered Notes, the holder of this
permanent Global Note shall in all respects be entitled to the same benefits as
if it were the holder of the Definitive Notes for which it may be exchanged and
as if such Definitive Notes had been issued on the Issue Date.

Payments

No person shall be entitled to receive any payment in respect of the Notes
represented by this permanent Global Note that falls due after an Exchange Date
for such Notes, unless upon due presentation of this permanent Global Note for
exchange, delivery of Definitive Notes or Certificates is improperly withheld or
refused by or on behalf of the Issuer or the Issuer does not perform or comply
with any one or more of what are expressed to be its obligations under any
Definitive Notes.

Payments in respect of this permanent Global Note shall be made to its holder
against presentation and (if no further payment falls to be made on it)
surrender of it at the specified office of the Issuing and Paying Agent or of
any other Paying Agent provided for in the Conditions. A record of each such
payment shall be endorsed on the First or Second Schedule hereto, as
appropriate, by the Issuing and Paying Agent or by the relevant Paying Agent,
for and on behalf of the Issuing and Paying Agent, which endorsement shall
(until the contrary is proved) be prima facie evidence that the payment in
question has been made.

Prescription

Claims in respect of principal and interest (as each is defined in the
Conditions) in respect of this permanent Global Note shall become void unless it
is presented for payment within a period of 10 years (in the case of principal)
and 5 years (in the case of interest) from the appropriate Relevant Date.

Meetings

The holder of this permanent Global Note shall be treated at any meeting of
Noteholders, as having one vote in respect of each principal amount of Notes
equal to the minimum Denomination of the Notes for which this permanent Global
Note may be exchanged.

Cancellation

Cancellation of any Note represented by this permanent Global Note that is
required by the Conditions to be cancelled (other than upon its redemption)
shall be effected by reduction in the principal amount of this permanent Global
Note representing such Note on its presentation to or to the order of the
Issuing and Paying Agent for endorsement in the First Schedule hereto, whereupon
the principal amount hereof shall be reduced for all purposes by the amount so
cancelled and endorsed.

the Issuer giving notice to the Noteholders within the time limits set out in

permanent Global Note is held on behalf of Euroclear, Cedel Bank or any other
clearing system) to Euroclear, Cedel Bank or such other clearing system, as the
case may be, or otherwise to the holder of this permanent Global Note, rather
than by publication as required by the Conditions.

            holder and any previous holder of this permanent Global Note all
            rights of set-off or counterclaim that would or might otherwise be
            available to it in respect of the obligations evidenced by this
            Global Note and

      (iii) payment upon due presentation of this permanent Global Note as
            provided herein shall operate as a good discharge against such
            holder and all previous holders of this permanent Global Note.

No provision of this permanent Global Note shall alter or impair the obligation
of the Issuer to pay the principal and premium of and interest on the Notes when

purpose until authenticated by or on behalf of the Issuing and Paying Agent.

      (i)   if the Notes represented by this Global Certificate are held on

                                     Part C
                        Terms and Conditions of the Notes

The Notes are constituted by a Trust Deed (as amended or supplemented as at the
date of issue of the Notes (the "Issue Date"), the "Trust Deed") dated 4th
November 1997 between the Issuer and The Law Debenture Trust Corporation p.l.c.
(the "Trustee", which expression shall include all persons for the time being
the trustee or trustees under the Trust Deed) as trustee for the Noteholders (as
defined below). These terms and conditions include summaries of, and are subject
to, the detailed provisions of the Trust Deed, which includes the form of the
Bearer Notes, Certificates, Receipts, Coupons and Talons referred to below. An
Agency Agreement (as amended or supplemented as at the Issue Date, the "Agency
Agreement") dated 4th November 1997 has been entered into in relation to the
Notes between the Issuer, the Trustee, Citibank, N.A., London as initial issuing
and paying agent and the other agents named in it. The issuing and paying agent,
the paying agents, the registrar, the transfer agents and the calculation
agent(s) for the time being (if any) are referred to below respectively as the
"Issuing and Paying Agent", the "Paying Agents" (which expression shall include
the Issuing and Paying Agent), the "Registrar", the "Transfer Agents" (which
expression shall include the Registrar) and the "Calculation Agent(s)". Copies
of the relevant Pricing Supplement, Trust Deed and the Agency Agreement are
available for inspection during usual business hours at the registered office of
the Trustee (presently at Princes House, 93 Gresham Street, London EC2V 7LY) and
at the specified offices of the Paying Agents and the Transfer Agents.

The Noteholders, the holders of the interest coupons (the "Coupons")
appertaining to interest bearing Notes in bearer form and, where applicable in
the case of such Notes, talons for further Coupons (the "Talons") (the
"Couponholders") and the holders of the receipts for the payment of instalments
of principal (the "Receipts") relating to Notes in bearer form of which the
principal is payable in instalments are entitled to the benefit of, are bound
by, and are deemed to have notice of, all the provisions of the Trust Deed and
the relevant Pricing Supplement and are deemed to have notice of those
provisions applicable to them of the Agency Agreement.

1. Form, Denomination and Title

The Notes are issued in bearer form ("Bearer Notes", which expression includes
Notes that are specified to be Exchangeable Bearer Notes), in registered form
("Registered Notes") or in bearer form exchangeable for Registered Notes
("Exchangeable Bearer Notes") in each case in the Denomination(s) shown thereon.

All Registered Notes shall have the same Denomination. Where Exchangeable Bearer
Notes are issued, the Registered Notes for which they are exchangeable shall
have the same Denomination as the lowest denomination of Exchangeable Bearer
Notes.

Bearer Notes are serially numbered and are issued with Coupons (and, where
appropriate, a Talon) attached, save in the case of Notes that do not bear
interest in which case references to interest (other than in relation to
interest due after the Maturity Date), Coupons and Talons in these Conditions
are not applicable. Any Bearer Note the principal amount of which is redeemable
in instalments is issued with one or more Receipts attached.

Registered Notes are represented by registered certificates ("Certificates")
and, save as provided in Condition 2(c), each Certificate shall represent the
entire holding of Registered Notes by the same holder.

Title to the Bearer Notes and the Receipts, Coupons and Talons shall pass by
delivery. Title to the Registered Notes shall pass by registration in the
register that the Issuer shall procure to be kept by the Registrar in accordance
with the provisions of the Agency Agreement (the "Register"). Except as ordered
by a court of competent jurisdiction or as required by law, the holder (as
defined below) of any Note, Receipt, Coupon or Talon shall be deemed to be and
may be treated as its absolute owner for all purposes whether or not it is
overdue and regardless of any notice of ownership, trust or an interest in it,
any writing on it (or on the Certificate representing it) or its theft or loss
(or that of the related Certificate) and no person shall be liable for so
treating the holder.

In these Conditions, "Noteholder" means the bearer of any Bearer Note and the
Receipts relating to it or the person in whose name a Registered Note is
registered (as the case may be), "holder" (in relation to a Note, Receipt,
Coupon or Talon) means the bearer of any Bearer Note, Receipt, Coupon or Talon
or the person in whose name a Registered Note is registered (as the case may be)
and capitalised terms have the meanings given to them hereon, the absence of any
such meaning indicating that such term is not applicable to the Notes.

2. Exchanges of Exchangeable Bearer Notes and Transfers of Registered Notes

(a) Exchange of Exchangeable Bearer Notes

Subject as provided in Condition 2(f), Exchangeable Bearer Notes may be
exchanged for the same aggregate principal amount of Registered Notes at the
request in writing of the relevant Noteholder and upon surrender of each
Exchangeable Bearer Note to be exchanged, together with all unmatured Receipts.
Coupons and Talons relating to it, at the specified office of any Transfer
Agent: provided, however, that where an Exchangeable Bearer Note is surrendered
for exchange after the Record Date (as defined in Condition 7(b)) for any
payment of interest, the Coupon in respect of that payment of interest need not
be surrendered with it. Registered Notes may not be exchanged for Bearer Notes.
Bearer Notes of one Denomination may not be exchanged for Bearer Notes of
another Denomination. Bearer Notes that are not Exchangeable Bearer Notes may
not be exchanged for Registered Notes.
<PAGE>
(b) Transfer of Registered Notes

One or more Registered Notes may be transferred upon the surrender (at the
specified office of the Registrar or any Transfer Agent) of the Certificate
representing such Registered Notes to be transferred, together with the form of
transfer endorsed on such Certificate duly completed and executed and any other
evidence as the Registrar or Transfer Agent may reasonably require. In the case
of a transfer of part only of a holding of Registered Notes represented by one
Certificate, a new Certificate shall be issued to the transferee in respect of
the part transferred and a further new Certificate in respect of the balance of
the holding not transferred shall be issued to the transferor.

(c) Exercise of Options or Partial Redemption in Respect of Registered Notes

In the case of an exercise of an Issuer's or Noteholders' option in respect of,
or a partial redemption of, a holding of Registered Notes represented by a
single Certificate, a new Certificate shall be issued to the holder to reflect
the exercise of such option or in respect of the balance of the holding not
redeemed. In the case of a partial exercise of an option resulting in Registered
Notes of the same holding having different terms, separate Certificates shall be
issued in respect of those Notes of that holding that have the same terms. New
Certificates shall only be issued against surrender of the existing Certificates
to the Registrar or any Transfer Agent. In the case of a transfer of Registered
Notes to a person who is already a holder of Registered Notes, a new Certificate
representing the enlarged holding shall only be issued against surrender of the
Certificate representing the existing holding.

(d) Delivery of New Certificates

Each new Certificate to be issued pursuant to Conditions 2(a), (b) or (c) shall
be available for delivery within five business days of receipt of the request
for exchange, form of transfer or Exercise Notice or surrender of the
Certificate for exchange. Delivery of the new Certificate(s) shall be made at
the specified office of the Transfer Agent or of the Registrar (as the case may
be) to whom delivery or surrender of such request for exchange, form of
transfer, Exercise Notice or Certificate shall have been made or, at the option
of the holder making such delivery or surrender as aforesaid and as specified in
the relevant request for exchange, form of transfer, Exercise Notice or
otherwise in writing, be mailed by uninsured post at the risk of the holder
entitled to the new Certificate to such address as may be so specified, unless
such holder requests otherwise and pays in advance to the relevant Agent the
costs of such other method of delivery and/or such insurance as it may specify.
In this Condition 2(d), "business day" means a day, other than a Saturday or
Sunday, on which banks are open for business in the place of the specified
office of the relevant Transfer Agent or the Registrar.

(e) Exchange Free of Charge

Exchange and transfer of Notes and Certificates on registration, transfer,
exercise of an option or partial redemption shall be effected without charge by
or on behalf of the Issuer, the Registrar or the Transfer Agents, but upon
payment of any tax or other governmental charges that may be imposed in relation
to it (or the giving of such indemnity as the Registrar or the relevant Transfer
Agent may reasonably require).

(f) Closed Periods

No Noteholder may require the transfer of a Registered Note to be registered or
an Exchangeable Bearer Note to be exchanged for one or more Registered Note(s)
(i) during the period of 15 days ending on the due date for redemption of, or
payment of any Instalment Amount in respect of, that Note, (ii) during the
period of 15 days prior to any date on which Notes may be called for redemption
by the Issuer at its option pursuant to Condition 6(d), (iii) after any such
Note has been called for redemption or (iv) during the period of seven days
ending on (and including) any Record Date. An Exchangeable Bearer Note called
for redemption may, however, be exchanged for one or more Registered Note(s) in
respect of which the Certificate is simultaneously surrendered not later than
the relevant Record Date.

3. Status

The Notes and the Receipts and Coupons constitute (subject to Condition 4)
unsecured obligations of the Issuer and shall at all times rank pari passu and
without any preference among themselves. The payment obligations of the Issuer
under the Notes and the Receipts and Coupons shall, save for such exceptions as
may be provided by applicable legislation and subject to Condition 4, at all
times rank at least equally with all other unsecured and unsubordinated
indebtedness and monetary obligations of the Issuer, present and future.

4. Negative Pledge

So long as any of the Notes remains outstanding (as defined in the Trust Deed)
the Issuer will ensure that no Relevant Indebtedness of the Issuer or any
Relevant Subsidiary (as defined in Condition 6) or of any other person and no
guarantee by the Issuer or any Relevant Subsidiary of any Relevant Indebtedness
(as defined in Condition 6) of any person will be secured by a mortgage, charge,
lien, pledge or other security interest (each a "Security Interest") upon, or
with respect to, any of the present or future business, undertaking, assets or
revenues (including any uncalled capital) of the Issuer or any Relevant
Subsidiary unless the Issuer shall, before or at the same time as the creation
of the Security Interest, take any and all action necessary to ensure that:

(i) all amounts payable by it under the Notes, the Receipts, the Coupons and the
Trust Deed are secured equally and rateably with the Relevant Indebtedness or
guarantee, as the case may be, by the Security Interest to the satisfaction of
the Trustee; or
<PAGE>

(ii) such other Security Interest or guarantee or other arrangement (whether or
not including the giving of a Security Interest) is provided in respect of all
amounts payable by the Issuer under the Notes, the Receipts, the Coupons and the
Trust Deed either (i) as the Trustee shall in its absolute discretion deem not
materially less beneficial to the interests of the Noteholders or (ii) as shall
be approved by an Extraordinary Resolution (as defined in the Trust Deed) of the
Noteholders,

save that the Issuer or any Relevant Subsidiary may create or have outstanding a
Security Interest in respect of any Relevant Indebtedness and/or any guarantees
given by the Issuer or any Relevant Subsidiary in respect of any Relevant
Indebtedness of any person (without the obligation to provide a Security
Interest or guarantee or other arrangement in respect of the Notes, the
Receipts, the Coupons and the Trust Deed as aforesaid) where (1) such Relevant
Indebtedness has an initial maturity of not less than twenty years and is of a
maximum aggregate amount outstanding at any time not exceeding the greater of
(pound)250,000,000 or 20% of the Capital and Reserves (as defined in Condition
6) or (2) such Security Interest is provided in respect of a company becoming a
Subsidiary of the Issuer after the date of the relevant Pricing Supplement and
where such Security Interest existed at the time that company becomes a
Subsidiary of the Issuer (provided that such Security Interest was not created
in contemplation of that company becoming a Subsidiary of the Issuer and the
principal amount secured at the time of that company becoming a Subsidiary of
the Issuer is not subsequently increased).

5. Interest and Other Calculations

(a) Interest Rate and Accrual

Each Note bears interest on its outstanding principal amount from the Interest
Commencement Date at the rate per annum (expressed as a percentage) equal to the
Interest Rate, such interest being payable in arrear on each Interest Payment
Date.

Interest shall cease to accrue on each Note on the due date for redemption
unless, upon due presentation, payment of principal is improperly withheld or
refused, in which event interest shall continue to accrue (as well after as
before judgment) at the Interest Rate in the manner provided in this Condition 5
to the Relevant Date (as defined in Condition 8).

(b) Business Day Convention

If any date referred to in these Conditions that is specified to be subject to
adjustment in accordance with a Business Day Convention would otherwise fall on
a day that is not a Business Day, then, if the Business Day Convention specified
is (i) the Floating Rate Business Day Convention, such date shall be postponed
to the next day that is a Business Day unless it would thereby fall into the
next calendar month, in which event (A) such date shall be brought forward to
the immediately preceding Business Day and (B) each subsequent such date shall
be the last Business Day of the month in which such date would have fallen had
it not been subject to adjustment, (ii) the Following Business Day Convention,
such date shall be postponed to the next day that is a Business Day; (iii) the
Modified Following Business Day Convention, such date shall be postponed to the
next day that is a Business Day unless it would thereby fall into the next
calendar month, in which event such date shall be brought forward to the
immediately preceding Business Day or (iv) the Preceding Business Day
Convention, such date shall be brought forward to the immediately preceding
Business Day.

(c) Interest Rate on Floating Rate Notes

Subject to paragraph (v) below, if the Interest Rate is specified in the Pricing
Supplement as being Floating Rate, the Interest Rate for each Interest Accrual
Period shall be determined by the Calculation Agent at or about the Relevant
Time on the Interest Determination Date in respect of each Interest Accrual
Period in accordance with the following

(i) if the Primary Source for the Floating Rate is a Page, subject as provided
below, the Interest Rate shall be:

(x) the Relevant Rate (where such Relevant Rate on such Page is a composite
quotation or is customarily supplied by one entity); or

(y) the arithmetic mean of the Relevant Rates of the persons whose Relevant
Rates appear on that Page,

in each case appearing on such Page at the Relevant Time on the Interest
Determination Date

(ii) if the Page specified in the Pricing Supplement as a Primary Source
permanently ceases to quote the Relevant Rate(s) but such quotation(s) is/are
available from another page, section or other part of such information service
selected by the Calculation Agent (the "Replacement Page"), the Replacement Page
shall be substituted as the Primary Source for Interest Rate Quotations and if
no Replacement Page exists but such quotation(s) is/are available from a page,
section or other part of a different information service selected by the
Calculation Agent and approved by the Issuer (the "Secondary Replacement Page"),
the Secondary Replacement Page shall be substituted as the Primary Source for
Interest Rate Quotations

(iii) if the Primary Source for the Floating Rate is Reference Banks (as defined
below) or if sub-paragraph (i)(x) applies and no Relevant Rate appears on the
Page at the Relevant Time on the Interest Determination Date or if sub-paragraph
(i)(y) above applies and fewer than two Relevant Rates appear on the Page at the
Relevant Time on the Interest Determination Date, subject as provided below, the
Interest Rate shall be the arithmetic mean of the Relevant Rates that each of
the Reference Banks is quoting to leading banks in the Relevant Financial Centre
at the Relevant Time on the Interest Determination Date, as determined by the
Calculation Agent

(iv) if paragraph (iii) above applies, and the Calculation Agent determines that
fewer than two Reference Banks are so quoting Relevant Rates, subject as
provided below, the Interest Rate shall be the arithmetic mean of the rates per
annum
<PAGE>
(expressed as a percentage) that the Calculation Agent determines to be the
rates (being the nearest equivalent to the Benchmark) in respect of a
Representative Amount of the Relevant Currency that at least two out of five
leading banks selected by the Calculation Agent in the principal financial
centre of the country of the Relevant Currency (the "Principal Financial
Centre") selected by the Calculation Agent are quoting at or about the Relevant
Time on the date on which such banks would customarily quote such rates for a
period commencing on the Effective Date for a period equivalent to the Specified
Duration (x) to leading banks carrying on business in Europe, or (if the
Calculation Agent determines that fewer than two of such banks are so quoting to
leading banks in Europe) (y) to leading banks carrying on business in the
Principal Financial Centre; except that, if fewer than two of such banks are so
quoting to leading banks in the Principal Financial Centre, the Interest Rate
shall be the Interest Rate determined on the previous Interest Determination
Date (after readjustment for any difference between any Margin, Rate Multiplier
or Maximum or Minimum Interest Rate applicable to the preceding Interest Accrual
Period and to the relevant Interest Accrual Period)

(v) where the Relevant Currency is Euro (provided that if the third stage of the
European economic and monetary union has not started, references to Euro as the
relevant currency shall mean ECU) and the Interest Rate is specified as being
Floating Rate, provisions relating to the calculation and determination of
interest will be specified in the relevant Pricing Supplement.

(d) Interest Rate on Zero Coupon Notes

Where a Note the Interest Rate of which is specified in the Pricing Supplement
to be Zero Coupon is repayable prior to the Maturity Date and is not paid when
due, the amount due and payable prior to the Maturity Date shall be the
Redemption Amount of such Note. As from the Maturity Date, the Interest Rate for
any overdue principal of such a Note shall be a rate per annum (expressed as a
percentage) equal to the Amortisation Yield (as defined in Condition 6(b)).

(e) Margin, Maximum/Minimum Interest Rates, Instalment Amounts and Redemption
    Amounts, Rate Multipliers and Rounding

(i) If any Margin or Rate Multiplier is specified in the Pricing Supplement
(either (x) generally, or (y) in relation to one or more Interest Accrual
Periods), an adjustment shall be made to all Interest Rates, in the case of (x),
or the Interest Rates for the specified Interest Accrual Periods, in the case of
(y), calculated in accordance with Condition 5(c) above by adding (if a positive
number) or subtracting the absolute value (if a negative number) of such Margin
or multiplying by such Rate Multiplier, subject always to the next paragraph.

(ii) If any Maximum or Minimum Interest Rate, Instalment Amount or Redemption
Amount is specified in the Pricing Supplement, then any Interest Rate,
Instalment Amount or Redemption Amount shall be subject to such maximum or
minimum, as the case may be.

(iii) For the purposes of any calculations required pursuant to these Conditions
(unless otherwise specified in the Pricing Supplement), (x) all percentages
resulting from such calculations shall be rounded, if necessary, to the nearest
one hundred-thousandth of a percentage point (with halves being rounded up), (y)
all figures shall be rounded to seven significant figures (with halves being
rounded up) and (z) all currency amounts that fall due and payable shall be
rounded to the nearest unit of such currency (with halves being rounded up),
save in the case of yen, which shall be rounded down to the nearest yen. For
these purposes "unit" means, with respect to any currency other than ECU, the
lowest amount of such currency that is available as legal tender in the country
of such currency and, (a) with respect to ECU, means 0.01 ECU and (b) with
respect to Euro, means 0.01 Euro.

(f) Calculations

The amount of interest payable in respect of any Note for any period shall be
calculated by multiplying the product of the Interest Rate and the outstanding
principal amount of such Note by the Day Count Fraction, unless an Interest
Amount (or a formula for its calculation) is specified in respect of such
period, in which case the amount of interest payable in respect of such Note for
such period shall equal such Interest Amount (or be calculated in accordance
with such formula). Where any Interest Period comprises two or more Interest
Accrual Periods, the amount of interest payable in respect of such Interest
Period shall be the sum of the amounts of interest payable in respect of each of
those Interest Accrual Periods.

(g) Determination and Publication of Interest Rates, Interest Amounts,
    Redemption Amounts and Instalment Amounts

As soon as practicable after the Relevant Time on each Interest Determination
Date or such other time on such date as the Calculation Agent may be required to
calculate any Redemption Amount or Instalment Amount, obtain any quote or make
any determination or calculation, it shall determine the Interest Rate and
calculate the amount of interest payable (the "Interest Amounts") in respect of
each Denomination of the Notes for the relevant Interest Accrual Period,
calculate the Redemption Amount or Instalment Amount, obtain such quote or make
such determination or calculation, as the case may be, and cause the Interest
Rate and the Interest Amounts for each Interest Period and the relevant Interest
Payment Date and, if required to be calculated, the Redemption Amount or any
Instalment Amount to be notified to the Trustee, the Issuer, each of the Paying
Agents, the Noteholders, any other Calculation Agent appointed in respect of the
Notes that is to make a further calculation upon receipt of such information
and, if the Notes are listed on a stock exchange and the rules of such exchange
so require, such exchange as soon as possible after their determination but in
no event later than (i) the commencement of the relevant Interest Period, if
determined prior to such time, in the case of notification to such exchange of
an Interest Rate and Interest
<PAGE>

Amount, or (ii) in all other cases, the fourth Business Day after such
determination. Where any Interest Payment Date or Interest Period Date is
subject to adjustment pursuant to Condition 5(b), the Interest Amounts and the
Interest Payment Date so published may subsequently be amended (or appropriate
alternative arrangements made with the consent of the Trustee by way of
adjustment) without notice in the event of an extension or shortening of the
Interest Period. If the Notes become due and payable under Condition 10, the
accrued interest and the Interest Rate payable in respect of the Notes shall
nevertheless continue to be calculated as previously in accordance with this
Condition but no publication of the Interest Rate or the Interest Amount so
calculated need be made unless the Trustee otherwise requires. The determination
of each Interest Rate, Interest Amount, Redemption Amount and Instalment Amount,
the obtaining of each quote and the making of each determination or calculation
by the Calculation Agent(s) shall (in the absence of manifest error) be final
and binding upon all parties.

(h) Determination or Calculation by Trustee

If the Calculation Agent does not at any time for any reason determine or
calculate the Interest Rate for an Interest Period or any Interest Amount,
Instalment Amount or Redemption Amount, the Trustee shall do so (or shall
appoint an agent on its behalf to do so) and such determination or calculation
shall be deemed to have been made by the Calculation Agent. In doing so, the
Trustee shall apply the foregoing provisions of this Condition, with any
necessary consequential amendments, to the extent that, in its opinion, it can
do so, and, in all other respects it shall do so in such manner as it shall deem
fair and reasonable in all the circumstances.

quotations and decisions given, expressed, made or obtained for the purposes of
the provisions of this Condition 5, whether by the Calculation Agent or the

Agents and all Noteholders, Receiptholders and Couponholders and (in the absence
as aforesaid) no liability to the Issuer, the Noteholders, the Receiptholders or
the Couponholders shall attach to the Calculation Agent or the Trustee in
connection with the exercise or non-exercise by them of their powers, duties and
discretions pursuant to such provisions.

6. Redemption, Purchase and Options

(a) Redemption by Instalments and Final Redemption

(i) Unless previously redeemed, purchased and cancelled as provided in this
Condition 6 or the relevant Instalment Date (being one of the dates so specified
hereon) is extended pursuant to the Issuer's or any Noteholder's option in
accordance with Condition 6(d) or 6(e), each Note that provides for Instalment
Dates and Instalment Amounts shall be partially redeemed on each Instalment Date
at the related Instalment Amount specified in the Pricing Supplement. The
outstanding principal amount of each such Note shall be reduced by the
Instalment Amount (or, if such Instalment Amount is calculated by reference to a
proportion of the principal amount of such Note, such proportion) for all
purposes with effect from the related Instalment Date, unless payment of the
Instalment Amount is improperly withheld or refused on presentation of the
related Receipt, in which case, such amount shall remain outstanding until the
Relevant Date relating to such Instalment Amount.

(ii) Unless previously redeemed, purchased and cancelled as provided below or
its maturity is extended pursuant to the Issuer's or any Noteholder's option in
accordance with Condition 6(d) or 6(e), each Note shall be finally redeemed on
the Maturity Date specified in the Pricing Supplement at its Redemption Amount
(which, unless otherwise provided in the Pricing Supplement, is its principal
amount) or, in the case of a Note falling within paragraph (i) above, its final
Instalment Amount.

(b) Early Redemption of Zero Coupon Notes

(i) The Redemption Amount payable in respect of any Note that does not bear
interest prior to the Maturity Date, the Redemption Amount of which is not
linked to an index and/or a formula, upon redemption of such Note pursuant to
Condition 6(c) or 6(f) or upon it becoming due and payable as provided in
Condition 10 shall be the Amortised Face Amount (calculated as provided below)
of such Note.

(ii) Subject to the provisions of sub-paragraph (iii) below, the Amortised Face
Amount of any such Note shall be the scheduled Redemption Amount of such Note on
the Maturity Date discounted at a rate per annum (expressed as a percentage)
equal to the Amortisation Yield (which, if none is shown in the Pricing
Supplement, shall be such rate as would produce an Amortised Face Amount equal
to the issue price of the Notes if they were discounted back to their issue
price on the Issue Date) compounded annually. Where such calculation is to be
made for a period of less than one year, it shall be made on the basis of the
Day Count Fraction shown hereon.

(iii) If the Redemption Amount payable in respect of any such Note upon its
redemption pursuant to Condition 6(c) or 6(f) or upon it becoming due and
payable as provided in Condition 10 is not paid when due, the Redemption Amount
due and payable in respect of such Note shall be the Amortised Face Amount of
such Note as defined in sub-paragraph (ii) above, except that such sub-paragraph
shall have effect as though the reference therein to the date on which the Note
becomes due and payable were replaced by a reference to the Relevant Date. The
calculation of the Amortised Face Amount in accordance with this sub-paragraph
shall continue to be made (as well after as before judgment) until the Relevant
Date, unless the Relevant Date falls on or after the Maturity Date, in which
case the amount due and payable shall be the scheduled Redemption Amount of such
Note on the Maturity Date together with any interest that may accrue in
accordance with Condition 5(d).

(c) Redemption for Taxation Reasons

If, as a result of any amendment to or change in the laws or regulations of the
United Kingdom or of any political subdivision thereof or any authority therein
or thereof having power to tax or any change in the official or generally
accepted interpretation or application of such laws or regulations which becomes
effective on or after the date of the Trust Deed, the Issuer has or will become
obliged to pay any additional amounts as described in Condition 8 (and such
amendment or change has been evidenced by the delivery by the Issuer to the
Trustee (who shall accept such certificate and opinion as sufficient evidence
thereof) of (i) a certificate signed by two directors of the Issuer on behalf of
the Issuer stating that such amendment or change has occurred (irrespective of
whether such amendment or change is then effective), describing the facts
leading thereto and stating that such requirement cannot be avoided by the
Issuer, taking reasonable measures available to it and (ii) an opinion of
independent legal advisers of recognised standing to the effect that such
amendment or change has occurred (irrespective of whether such amendment or
change is then effective)), the Issuer may (having given not less than 30 nor
more
<PAGE>

than 90 days' notice to the Trustee and to the holders in accordance with
Condition 16) redeem all, but not some only, of the Notes (other than Notes in
respect of which the Issuer shall have given a notice of redemption pursuant to
Condition 6(d) or in respect of which a Noteholder shall have given a Put Event
Notice in accordance with Condition 6(f), in each case prior to any notice being
given under this Condition 6(c)) at their Redemption Amount, together with
accrued interest to the date fixed for such redemption, provided that no such
notice of redemption shall be given earlier than 90 days prior to the earliest
date on which the Issuer would be required to pay such additional amounts were a
payment in respect of the Notes then due.

(d) Redemption at the Option of the Issuer and Exercise of Issuer's Options

If so provided in the Pricing Supplement, the Issuer may, on giving irrevocable
notice to the Noteholders falling within the Issuer's Option Period, redeem, or
exercise the Issuer's option in relation to, all or, if so provided, some of the
Notes (other than Notes in respect of which the Issuer shall have given a notice
of redemption pursuant to Condition 6(c) or in respect of which a Noteholder
shall have given a Put Event Notice in accordance with Condition 6(f), in each
case prior to any notice being given under this Condition 6(d)) in the principal
amount or integral multiples thereof and on the date or dates so provided. Any
such redemption of Notes shall be at their Redemption Amount together with
interest accrued to the date fixed for redemption.

All Notes in respect of which any such notice is given shall be redeemed, or the
Issuer's option shall be exercised, on the date specified in such notice in
accordance with this Condition.

In the case of a partial redemption or a partial exercise of the Issuer's
option, the notice to Noteholders shall also contain the certificate numbers of
the Notes to be redeemed or in respect of which such option has been exercised,
which shall have been drawn in such place as the Trustee may approve and in such
manner as it deems appropriate, subject to compliance with any applicable laws
and stock exchange requirements. So long as the Notes are listed on the London
Stock Exchange or any other stock exchange and the rules of the relevant stock
exchange so require, the Issuer shall, once in each year in which there has been
a partial redemption of the Notes, cause to be published in a leading newspaper
of general circulation in London or as specified by such other stock exchange, a
notice specifying the aggregate principal amount of Notes outstanding and a list
of the Notes drawn for redemption but not surrendered.

(e) Redemption at the Option of Noteholders and Exercise of Noteholders'
    Options

If so provided in the Pricing Supplement, the Issuer shall, at the option of the
holder of any such Note, redeem such Note on the date or dates so provided at
its Redemption Amount together with interest accrued to the date fixed for
redemption.

To exercise such option or any other Noteholders' option that may be set out
hereon the holder must deposit (in the case of Bearer Notes) such Note (together
with all unmatured Receipts and Coupons and unexchanged Talons) with any Paying
Agent or (in the case of Registered Notes) the Certificate representing such
Note(s) with the Registrar or any Transfer Agent at its specified office,
together with a duly completed option exercise notice ("Exercise Notice" which
expression shall include any Put Notice (as defined below)) in the form
obtainable from any Paying Agent, the Registrar or any Transfer Agent (as
applicable) within the Noteholders' Option Period (which expression shall, in
the case of the exercise of the option referred to in Condition 6(f) below, mean
the Put Period (as defined below)). No Note or Certificate so deposited and
option exercised may be withdrawn without the prior consent of the Issuer,
except that such Note or Certificate will be returned to the relevant Noteholder
by the Paying Agent, the Registrar or Transfer Agent with which it has been
deposited if, prior to the due date for its redemption or the exercise of the
option, the Note becomes immediately due and payable or if upon due presentation
payment of the redemption moneys is not made or exercise of the option is
denied.

(f) Redemption at the Option of the Noteholders on a Put Event

If so provided in the Pricing Supplement, if, at any time while any of the Notes
remains outstanding, a Restructuring Event occurs and prior to the commencement
of or during the Restructuring Period an Independent Financial Adviser shall
have certified in writing to the Trustee that such Restructuring Event will not
be or is not, in its opinion, materially prejudicial to the interests of the
Noteholders, the following provisions of this Condition 6(f) shall cease to have
any further effect in relation to such Restructuring Event.

If, at any time while any of the Notes remains outstanding, a Restructuring
Event occurs and (subject to this Condition 6(f)) within the Restructuring
Period, either:

(i) if at the time such Restructuring Event occurs there are Rated Securities, a
Rating Downgrade in respect of such Restructuring Event also occurs; or

(ii) if at such time there are no Rated Securities, a Negative Rating Event also
occurs; and

an Independent Financial Adviser shall have certified in writing to the Trustee
that such Restructuring Event is, in its opinion, materially prejudicial to the
interests of the Noteholders (a "Negative Certification"), then, unless at any
time the Issuer shall have given a notice under Condition 6(c) or 6(d), the
holder of each Note will, upon the giving of a Put Event Notice (as defined
below), have the option (the "Put Option") to require the Issuer to redeem or,
at the option of the Issuer, purchase (or procure the purchase of) that Note on
the Put Date (as defined below), at its principal amount together with (or,
where purchased, together with an amount equal to) interest (if any) accrued to
(but excluding) the Put Date.
<PAGE>

An event shall be deemed not to be a Restructuring Event if, notwithstanding the
occurrence of a Rating Downgrade or a Negative Rating Event, the rating assigned
to the Rated Securities by any Rating Agency is subsequently increased to, or,
as the case may be, there is assigned to the Notes or other unsecured and
unsubordinated debt of the Issuer or a Relevant Subsidiary (or of any Subsidiary
of the Issuer which is guaranteed on an unsecured and unsubordinated basis by
the Issuer or a Relevant Subsidiary) having an initial maturity of five years or
more by any Rating Agency, an investment grade rating (BBB-/Baa3 or their
respective equivalents for the time being) or better prior to any Negative
Certification being issued.

Any certification by an Independent Financial Adviser as aforesaid as to whether
or not, in its opinion any Restructuring Event is materially prejudicial to the
interests of the Noteholders shall, in the absence of manifest error, be
conclusive and binding on the Trustee, the Issuer and the Noteholders.

Promptly upon, and in any event within 14 days after, the Issuer becoming aware
that a Put Event has occurred, the Issuer shall, and at any time upon the
Trustee becoming similarly so aware the Trustee may, and if so requested by the
holders of at least one-quarter in principal amount of the Notes then
outstanding shall, give notice (a "Put Event Notice") to the Noteholders in
accordance with Condition 16 specifying the nature of the Put Event and the
procedure for exercising the Put Option.

To exercise the Put Option, the holder of a Note must deposit (in the case of a
Bearer Note) such Note with any Paying Agent or (in the case of Registered
Notes) the Certificate representing such Note(s) with the Registrar or any
Transfer Agent at its specified office, on a day which is a Business Day in the
City of London and in the place of such specified office falling within the
period (the "Put Period") of 45 days after that on which a Put Event Notice is
given, accompanied by a duly completed and signed notice of exercise in the form
(for the time being current) obtainable from any specified office of any Paying
Agent, the Registrar or any Transfer Agent (as applicable) (a "Put Notice") and
in which the holder may specify a bank account to which payment is to be made
under this Condition 6. Where any Bearer Note is delivered without all Coupons
relating to it which mature after the day (the "Put Date") being the fifteenth
day after the date of expiry of the Put Period, the exercise of the Put Option
in respect of such Note shall be subject to the provision of such indemnity as
the Issuer may reasonably require. The Paying Agent to which such Note and Put
Notice or, as the case may be, the Registrar or Transfer Agent to which the
Certificate and Put Notice are delivered shall issue to the Noteholder concerned
a non-transferable receipt in respect of the Note so delivered. Payment in
respect of any Note so delivered shall be made, if the holder duly specifies in
the Put Notice an account with a bank to which payment is to be made, on the Put
Date by transfer to that bank account and, in every other case, on or after the
Put Date in each case against presentation and surrender or (as the case may be)
endorsement of such receipt at any specified office of any Paying Agent. A Put
Notice, once given, shall be irrevocable. For the purposes of Conditions 9, 10,
11, 12, 14, 16 and 17 and for certain other purposes specified in the Trust
Deed, receipts issued pursuant to this Condition 6(f) shall be treated as if
they were Notes. The Issuer shall redeem or, at the option of the Issuer,
purchase (or procure the purchase of) the relevant Note on the applicable Put
Date unless previously redeemed or purchased.

A Rating Downgrade or a Negative Rating Event or a non-investment grade rating
shall be deemed not to have occurred as a result or in respect of a
Restructuring Event if the Rating Agency making the relevant reduction in rating
or, where applicable, declining to assign a rating of at least investment grade
as provided in this Condition 6(f) does not announce or publicly confirm or
inform the Trustee in writing at its request that the reduction or, where
applicable, declining to assign a rating of at least investment grade was the
result, in whole or in part, of any event or circumstance comprised in or
arising as a result of the applicable Restructuring Event.

The Trust Deed provides that the Trustee is under no obligation to ascertain
whether a Restructuring Event, a Negative Rating Event or any event which could
lead to the occurrence of, or could constitute a, Restructuring Event has
occurred and until it shall have actual knowledge or express notice pursuant to
the Trust Deed to the contrary the Trustee may assume that no Restructuring
Event, Negative Rating Event or such other event has occurred. The Trust Deed
also provides that in determining whether or not a Restructuring Event has
occurred, the Trustee may rely solely on an opinion given in a certificate
signed by two directors of the Issuer.

date for redemption and provided that the Receipt is presented for payment
together with its relative Note), Notes (in the case of all other payments of
principal and, in the case of interest, as specified in Condition 7(f)(vi)) or
Coupons (in the case of interest, save as specified in Condition 7(f)(ii)), as
the case may be, at the specified office of any Paying Agent outside the United
States by a cheque payable in the currency in which such payment is due drawn
on, or, at the option of the holder, by transfer to an account denominated in
that currency with, a bank in the principal financial centre for that currency;
provided that (i) in the case of Euro, the transfer may be to, or the cheque
drawn on, an Euro account with a bank in Europe and (ii) until the start of the
third stage of European economic and monetary union, all payments in respect of
Notes which are expressed to be payable in Euro will be payable in ECU at the
rate of one ECU for one Euro by transfer to or cheque drawn on, an account
specified by the payee in London, Luxembourg, Paris or Brussels.

(b) Registered Notes

(i) Payments of principal (which for the purposes of this Condition 7(b) shall
include final Instalment Amounts but not other Instalment Amounts) in respect of
Registered Notes shall be made against presentation and surrender of the
relevant Certificates at the specified office of any of the Transfer Agents or
of the Registrar and in the manner provided in paragraph (ii) below.

Instalment Amounts other than final Instalment Amounts) on Registered Notes
shall be paid to the person shown on the Register at the close of business on
the fifteenth day before the due date for payment thereof (the "Record Date").
Payments of interest on each Registered Note shall be made in the currency in

centre of the country of the currency concerned and mailed to the holder (or to
the first named of joint holders) of such Note at its address appearing in the
Register. Upon application by the holder to the specified office of the
Registrar or any Transfer Agent before the Record Date and subject as provided
in paragraph (a) above, such payment of interest may be made by transfer to an
account in the relevant currency maintained by the payee with a bank in the
principal financial centre of the country of that currency.

(c) Payments in the United States

Notwithstanding the foregoing, if any Bearer Notes are denominated in U.S.
dollars, payments in respect thereof may be made at the specified office of any
Paying Agent in New York City in the same manner as aforesaid if (i) the Issuer
shall have appointed Paying Agents with specified offices outside the United
States with the reasonable expectation that such Paying Agents would be able to
make payment of the amounts on the Notes in the manner provided above when due,
(ii) payment in full of such amounts at all such offices is illegal or
effectively precluded by exchange controls or other similar restrictions on
payment or receipt of such amounts and (iii) such payment is then permitted by
United States law, without involving, in the opinion of the Issuer, any adverse
tax consequence to the Issuer.

(d) Payments Subject to Fiscal Laws

All payments are subject in all cases to any applicable fiscal or other laws,
regulations and directives, but without prejudice to the provisions of Condition
8. No commission or expenses shall be charged to the Noteholders or
Couponholders in respect of such payments.

(e) Appointment of Agents

The Issuing and Paying Agent, the Paying Agents, the Registrar, the Transfer
Agents and the Calculation Agent initially appointed by the Issuer and their
respective specified offices are listed below. The Issuing and Paying Agent, the
Paying Agents, the Registrar, the Transfer Agents and the Calculation Agent act
solely as agents of the Issuer and do not assume any obligation or relationship
of agency or trust for or with any Noteholder or Couponholder. The Issuer
reserves the right at any time with the approval of the Trustee to vary or
terminate the appointment of the Issuing and Paying Agent, any other Paying
<PAGE>

Agent, the Registrar, any Transfer Agent or the Calculation Agent and to appoint
additional or other Paying Agents or Transfer Agents, provided that the Issuer

relation to Registered Notes, (iii) a Transfer Agent in relation to Registered
Notes, (iv) one or more Calculation Agent(s) where the Conditions so require,
(v) Paying Agents having specified offices in at least two major European cities

In addition, the Issuer shall forthwith appoint a Paying Agent in New York City
in respect of any Bearer Notes denominated in U.S. dollars in the circumstances
described in paragraph (c) above.

Notice of any such change or any change of any specified office shall promptly
be given to the Noteholders.

(f) Unmatured Coupons and Receipts and Unexchanged Talons

(i) Unless the Pricing Supplement provides that the relative Coupons are to
become void upon the due date for redemption of those Notes, Bearer Notes should
be surrendered for payment together with all unmatured Coupons (if any)
appertaining thereto, failing which an amount equal to the face value of each
missing unmatured Coupon (or, in the case of payment not being made in full,
that proportion of the amount of such missing unmatured Coupon that the sum of
principal so paid bears to the total principal due) shall be deducted from the
Redemption Amount due for payment. Any amount so deducted shall be paid in the
manner mentioned above against surrender of such missing Coupon within a period
of 10 years from the Relevant Date for the payment of such principal (whether or
not such Coupon has become void pursuant to Condition 9).

(ii) If the Pricing Supplement so provides, upon the due date for redemption of
any Bearer Note, unmatured Coupons relating to such Note (whether or not
attached) shall become void and no payment shall be made in respect of them.

(iii) Upon the due date for redemption of any Bearer Note, any unexchanged Talon
relating to such Note (whether or not attached) shall become void and no Coupon
shall be delivered in respect of such Talon.

(iv) Upon the due date for redemption of any Bearer Note that is redeemable in
instalments, all Receipts relating to such Note having an Instalment Date
falling on or after such due date (whether or not attached) shall become void
and no payment shall be made in respect of them.

(v) Where any Bearer Note that provides that the relative unmatured Coupons are
to become void upon the due date for redemption of those Notes is presented for
redemption without all unmatured Coupons and any unexchanged Talon relating to
it, and where any Bearer Note is presented for redemption without all unmatured
Coupons and any unexchanged Talon relating to it, redemption shall be made only
against the provision of such indemnity as the Issuer may require.

(vi) If the due date for redemption of any Note is not a due date for payment of
interest, interest accrued from the preceding due date for payment of interest
or the Interest Commencement Date, as the case may be, shall only be payable
against presentation (and surrender if appropriate) of the relevant Bearer Note
or Certificate representing it, as the case may be. Interest accrued on a Note
that only bears interest after its Maturity Date shall be payable on redemption
of such Note against presentation of the relevant Note or Certificate
representing it, as the case may be.

(g) Talons

On or after the Interest Payment Date for the final Coupon forming part of a
Coupon sheet issued in respect of any Bearer Note, the Talon forming part of
such Coupon sheet may be surrendered at the specified office of the Issuing and
Paying Age, in exchange for a further Coupon sheet (and if necessary another
Talon for a further Coupon sheet) (but excluding any Coupons that may have
become void pursuant to Condition 9).

(h) Non-Business Days

If any date for payment in respect of any Note, Receipt or Coupon is not a
business day, the holder shall not be entitled to payment until the next
following business day nor to any interest or other sum in respect of such
postponed payment. In this paragraph, "business day" means a day (other than a
Saturday or a Sunday) on which banks and foreign exchange markets are open for
business in the relevant place of presentation, in such jurisdictions as shall
be specified as "Business Day Jurisdictions" hereon and:

(i) (in the case of a payment in a currency other than Euro) where payment is to
be made by transfer to an account maintained with a bank in the relevant
currency, on which foreign exchange transactions may be carried on in the
relevant currency in the principal financial centre of the country of such
currency or

(ii) (in the case of a payment in Euro, or, until the start of the third stage
of European economic and monetary union, the ECU) on which banks are open for
business and carrying out transactions in Euro (or ECU, as the case may be) in
the jurisdiction in which the Euro account (or ECU account, as the case may be)
specified by the payee is located.

(i) Euro and ECU Notes

(i) Definition of Euro and the ECU

References in these Conditions to the Euro are to the currency which is to be
introduced at the start of the third stage of the European economic and monetary
union pursuant to Article 1091(4) of the Treaty establishing the European
Communities as
<PAGE>

amended by the Treaty on European Union (the "Treaty"). References to the ECU
("ECU") are to ECU as referred to in Article 109(g) of the Treaty as defined in
Council Regulation (EC) No. 3320/94, that is from time to time used as the unit
of account of the EC. Changes to the ECU may be made by the EC, in which event
the ECU shall change accordingly.

(ii) Redenomination

Notes denominated in a currency that may, after the start of the third stage of
European economic and monetary union, be converted into Euros, may be subject to
redenomination, renominalisation and/or consolidation with other Notes then
denominated in Euros, as specified in the relevant Pricing Supplement.

8. Taxation

All payments of principal and interest in respect of the Notes, the Receipts and
the Coupons (other than payments of interest in respect of Registered Notes
which will be made subject to the deduction of any United Kingdom income tax
required to be withheld or deducted at source) shall be made free and clear of,
and without withholding or deduction for, any taxes, duties, assessments or
governmental charges of whatever nature imposed, levied, collected, withheld or
assessed by or within the United Kingdom or any authority therein or thereof
having power to tax, unless such withholding or deduction is required by law. In
that event, the Issuer shall pay such additional amounts as shall result in
receipt by the Noteholders and Couponholders of such amounts as would have been
received by them had no such withholding or deduction been required, except that
no such additional amounts shall be payable with respect to any Note, Receipt or
Coupon:

(a) to, or to a third party on behalf of, a holder who is liable to such taxes,
duties, assessments or governmental charges in respect of such Note, Receipt or
Coupon by reason of his having some connection with the United Kingdom other
than the mere holding of the Note, Receipt or Coupon; or

(b) presented (or in respect of which the Certificate representing it is
presented) for payment more than 30 days after the Relevant Date except to the
extent that the holder of it would have been entitled to such additional amounts
on presenting it for payment on the thirtieth day; or

(c) presented for payment in the United Kingdom.*

As used in these Conditions, "Relevant Date" in respect of any Note, Receipt or
Coupon means the date on which payment in respect of it first becomes due or (if
any amount of the money payable is improperly withheld or refused) the date on
which payment in full of the amount outstanding is made or (if earlier) the date
seven days after that on which notice is duly given to the Noteholders that,
upon further presentation of the Note (or relative Certificate), Receipt or
Coupon being made in accordance with the Conditions, such payment will be made,
provided that payment is in fact made upon such presentation. References in
these Conditions to (i) "principal" shall be deemed to include any premium
payable in respect of the Notes, all Instalment Amounts, Redemption Amounts,
Amortised Face Amounts and all other amounts in the nature of principal payable
pursuant to Condition 6 or any amendment or supplement to it, (ii) "interest"
shall be deemed to include all Interest Amounts and all other amounts payable
pursuant to Condition 5 or any amendment or supplement to it and (iii)
"principal" and/or "interest" shall be deemed to include any additional amounts
that may be payable under this Condition or any undertaking given in addition to
or in substitution for it under the Trust Deed.

9. Prescription

Claims against the Issuer for payment in respect of the Notes, Receipts and
Coupons (which, for this purpose, shall not include Talons) shall be prescribed
and become void unless made within 10 years (in the case of principal) or five
years (in the case of interest) from the appropriate Relevant Date in respect of
them.

10. Events of Default

The Trustee at its discretion may, and if so requested in writing by the holders
of at least one-quarter in principal amount of the Notes then outstanding or if
so directed by an Extraordinary Resolution of the Noteholders shall, subject to
being indemnified to its satisfaction, (but, in the case of the happening of any
of the events mentioned in sub-paragraphs (b), (c), (e), (f), (g) and (h) below,
only if the Trustee shall have certified in writing to the Issuer that such
event is, in its opinion, materially prejudicial to the interests of the
Noteholders), give notice to the Issuer that the Notes are, and they shall
accordingly thereby forthwith become, immediately due and repayable at their
principal amount together with accrued interest (as provided in the Trust Deed)
if any of the following events (each an "Event of Default") shall have occurred
(unless such Event of Default has been remedied to the satisfaction of the
Trustee):

(a) if default is made for a period of 14 days or more in the payment of any
principal or the purchase price due in respect of any Notes pursuant to
Condition 6 or 21 days or more in the payment of any interest due in respect of
the Notes or any of them; or
<PAGE>

(b) if the Issuer fails to perform or observe any of its other obligations under
the Notes or the Trust Deed and (except where the Trustee shall have certified
to the Issuer in writing that it considers such failure to be incapable of
remedy in which case no such notice or continuation as is hereinafter mentioned
will be required) such failure continues for the period of 60 days (or such
longer period as the Trustee may in its absolute discretion permit) next
following the service by the Trustee of notice on the Issuer requiring the same
to be remedied; or

(c) if (i) any other indebtedness for borrowed money of the Issuer or any
Principal Subsidiary becomes due and repayable prior to its stated maturity by
reason of an event of default or (ii) any such indebtedness for borrowed money
is not paid when due or, as the case may be, within any applicable grace period
(as originally provided) or (iii) the Issuer or any Principal Subsidiary fails
to pay when due (or, as the case may be, within any originally applicable grace
period) any amount payable by it under any present or future guarantee for, or
indemnity in respect of, any indebtedness for borrowed money of any person or
(iv) any security given by the Issuer or any Principal Subsidiary for any
indebtedness for borrowed money of any person or for any guarantee or indemnity
of indebtedness for borrowed money of any person becomes enforceable by reason
of default in relation thereto and steps are taken to enforce such security,
save in any such case where there is a bona fide dispute as to whether the
relevant indebtedness for borrowed money or any such guarantee or indemnity as
aforesaid shall be due and payable, provided that the aggregate amount of the

11. Meetings of Noteholders, Modification, Waiver and Substitution

(a) Meetings of Noteholders

The Trust Deed contains provisions for convening meetings of Noteholders to
consider matters affecting their interests, including the modification of any of
the terms and conditions of the Notes or any provisions of the Trust Deed. Any
such modification may be made if sanctioned by an Extraordinary Resolution. The
quorum for any meeting convened to consider an Extraordinary Resolution will be
one or more persons holding or representing a clear majority in principal amount
of the Notes for the time being outstanding, or at any adjourned meeting, one or
more persons being or representing Noteholders whatever the principal amount of
the Notes held or represented, unless the business of such meeting includes
consideration of proposals, inter alia (i) to postpone the maturity or
redemption of the Notes, any Instalment Date or any date for payment of any
interest or Interest Amount on the Notes, (ii) to reduce or cancel the principal
amount of, or any Instalment Amount of, or any premium payable on redemption of,
the Notes, (iii) to reduce the rate or rates of interest in respect of the Notes
or to vary the method or basis of calculating the rate or rates or amount of
interest or the basis for calculating any Interest Amount in respect of the
Notes, (iv) if a Minimum and/or a Maximum Interest Rate, Instalment Amount or
Redemption Amount is shown hereon to reduce any such Minimum and/or Maximum,
(v) to vary any method of, or basis for, calculating the Redemption Amount,
including the method of calculating the Amortised Face Amount, (vi) to vary the
currency or currencies of payment or denomination of the Notes, (vii) to take
any steps that as specified hereon may only be taken following approval by an
Extraordinary Resolution to which the special quorum provisions apply, or (viii)
to modify the provisions concerning the quorum required at any meeting of
Noteholders or the majority required to pass the Extraordinary Resolution, in
which case the necessary quorum shall be one or more persons holding or
representing not less than two-thirds, or at any adjourned meeting not less than
one-third, in principal amount of the Notes for the time being outstanding. Any
Extraordinary Resolution duly passed shall be binding on Noteholders (whether or
not they were present at the meeting at which such resolution was passed) and on
all Couponholders.

These Conditions may be amended, modified or varied in relation to any Series of
Notes by the terms of the relevant Pricing Supplement in relation to such
Series.

(b) Modification of the Trust Deed

The Trustee may agree, without the consent of the Noteholders or Couponholders,
to (i) any modification of any of the provisions of the Trust Deed, the Notes or
the Coupons that is of a formal, minor or technical nature or is made to correct
a manifest error, and (ii) any other modification (except as mentioned in the
Trust Deed), and any waiver or authorisation of any breach or proposed breach,
of any of the provisions of the Trust Deed that is in the opinion of the Trustee
not materially prejudicial to the interests of the Noteholders. Any such
modification, authorisation or waiver shall be binding on the Noteholders and
the Couponholders and, if the Trustee so requires, such modification shall be
notified to the Noteholders as soon as practicable.

(c) Substitution

The Trust Deed contains provisions permitting the Trustee to agree, subject to
such amendment of the Trust Deed and such other conditions as the Trustee may
require, but without the consent of the Noteholders or the Couponholders, to the
substitution of any other company in place of the Issuer, or of any previous
substituted company, as principal debtor under the Trust Deed and the Notes. In
the case of such a substitution the Trustee may agree, without the consent of
the Noteholders or the Couponholders, to a change of the law governing the
Notes, the Receipts, the Coupons, the Talons and/or the Trust Deed provided that
such change would not in the opinion of the Trustee be materially prejudicial to
the interests of the Noteholders.

(d) Entitlement of the Trustee

In connection with the exercise of its functions (including but not limited to
those referred to in this Condition) the Trustee shall have regard to the
interests of the Noteholders as a class and shall not have regard to the
consequences of such exercise for individual Noteholders or Couponholders and
the Trustee shall not be entitled to require, nor shall any Noteholder or
Couponholder be entitled to claim, from the Issuer any indemnification or
payment in respect of any tax consequence of any such exercise upon individual
Noteholders or Couponholders.

12. Replacement of Notes, Certificates, Receipts, Coupons and Talons

If a Note, Certificate, Receipt, Coupon or Talon is lost, stolen, mutilated,
defaced or destroyed, it may be replaced, subject to applicable laws,
regulations and stock exchange regulations, at the specified office of the
Issuing and Paying Agent (in the case of Bearer Notes, Receipts, Coupons or
Talons) and of the Registrar (in the case of Certificates) or such other Paying
Agent or Transfer Agent, as the case may be, as may from time to time be
designated by the Issuer for the purpose and notice of whose designation is
given to Noteholders, in each case on payment by the claimant of the fees and
costs incurred in connection therewith and on such terms as to evidence,
security and indemnity (which may provide, inter alia, that if the allegedly
lost, stolen or destroyed Note, Certificate, Receipt, Coupon or Talon is
subsequently presented for payment or, as the case may be, for exchange for
further Coupons, there shall be paid to the Issuer on demand the amount payable
by the Issuer in respect of such Notes, Certificates, Receipts, Coupons or
further Coupons) and otherwise as the Issuer may reasonably require. Mutilated
or defaced Notes, Certificates, Receipts, Coupons or Talons must be surrendered
before replacements will be issued.
<PAGE>

13. Further Issues

The Issuer may from time to time without the consent of the Noteholders or
Couponholders create and issue further securities either having the same terms
and conditions as the Notes in all respects (or in all respects except for the
first payment of interest on them) and so that such further issue shall be
consolidated and form a single series with the outstanding securities of any
series (including the Notes) or upon such terms as the Issuer may determine at
the time of their issue. References in these Conditions to the Notes include
(unless the context requires otherwise) any other securities issued pursuant to
this Condition and forming a single series with the Notes. Any further
securities forming a single series with the outstanding securities of any series
(including the Notes) constituted by the Trust Deed or any deed supplemental to
it shall, and any other securities may (with the consent of the Trustee), be
constituted by the Trust Deed. The Trust Deed contains provisions for convening
a single meeting of the Noteholders and the holders of securities of other
series where the Trustee so decides.

14. Enforcement

At any time after the Notes become due and payable, the Trustee may, as its
discretion and without further notice, institute such proceedings against the
Issuer as it may think fit to enforce the terms of the Trust Deed, but it need
not take any such proceedings unless (a) it shall have been so directed by an
Extraordinary Resolution or so requested in writing by holders of at least
one-fifth in principal amount of the Notes outstanding, and (b) it shall have
been indemnified to its satisfaction. No Noteholder, Receiptholder or
Couponholder may proceed directly against the Issuer unless the Trustee, having
become bound so to proceed fails to do so within a reasonable time and such
failure is continuing.

15. Indemnification of the Trustee

The Trust Deed contains provisions for the indemnification of the Trustee and
for its relief from responsibility. The Trustee is entitled to enter into
business transactions with the Issuer and any entity related to the Issuer
without accounting for any profit.

16. Notices

Notices to the holders of Registered Notes shall be mailed to them at their
respective addresses in the Register and deemed to have been given on the fourth
weekday (being a day other than a Saturday or a Sunday) after the date of
mailing. Notices to the holders of Bearer Notes shall be valid if published in a
daily newspaper of general circulation in London (which is expected to be the
Financial Times). The Issuer shall also ensure that notices are duly published
in a manner which complies with the rules and regulations of any other stock
exchange on which the Notes are, for the time being, listed. Any such notice
shall be deemed to have been given on the date of such publication or, if
published more than once or on different dates, on the first date on which
publication is made, as provided above.

Couponholders shall be deemed for all purposes to have notice of the contents of
any notice given to the holders of Bearer Notes in accordance with this
Condition.

17. Governing Law and Jurisdiction

(a) Governing Law

The Trust Deed, the Notes, the Receipts, the Coupons and the Talons are governed
by, and shall be construed in accordance with, English law.

(b) Jurisdiction

The courts of England are to have jurisdiction to settle any disputes that may
arise out of or in connection with any Notes, Receipts, Coupons or Talons and
accordingly any legal action or proceedings arising out of or in connection with
any Notes, Receipts, Coupons or Talons ("Proceedings") may be brought in such
courts. The Issuer has in the Trust Deed irrevocably submitted to the
jurisdiction of such courts.

(c) Service of Process

The Issuer, in accordance with the Trust Deed, will appoint its London office,
whose address is at 54 Queen Anne Street, London W1M 9LA to act as its agent in
England to receive, for it and on its behalf, service of process in any
Proceedings in England.
