                                    (whether or not a Separate Business)
                                    together with a description of the basis of
                                    that charge; or

                                       19

 
                           (bb)     determined by apportionment or allocation
                                    between any Separate Business and any other

                                    Business) together with a description of the
                                    basis of the apportionment or allocation;
                                    and

                  (ii)     the first six months of the financial year commencing

                  Separate Business to which the statements relate; and

         (d)      deliver to the Director a copy of the account referred to in
                  sub-paragraph (b) (ii) above, the Auditors' report referred to
                  in sub-paragraph (c) above and the accounting statements
                  referred to in sub-paragraph (b) (i) above as soon as
                  reasonably practicable, and in any event not later than three
                  months after the end of the period to which it relates in the
                  case of the account referred to in sub-paragraph (b) (ii) and
                  six months after the end of the financial year to which they
                  relate in the case of the accounting statements and Auditors'
                  report referred to in sub-paragraphs (b) (i) and (c) above.

4.       Unless the Director so specifies in directions issued for the purposes
         of this Condition or with his prior written approval the Licensee shall
         not in relation to the accounting statements in respect of a financial
         year change the bases of charge or apportionment or allocation referred
         to in sub-paragraph (b) (i) of paragraph 3 from those applied in
         respect of the previous financial year.

 5.      Where, in relation to the accounting statements in respect of a
         financial year, the

                                       20

 
         Licensee has changed such bases of charge or apportionment or
         allocation from those adopted for the immediately preceding financial
         year, the Licensee shall, if so directed in directions issued by the
         Director, in addition to preparing accounting statements on those bases
         which it has adopted, prepare such accounting statements on the bases
         which applied in respect of the immediately preceding financial year.

6.       Accounting statements in respect of a financial year prepared under
         sub-paragraph (b) (i) of paragraph 3 shall, so far as reasonably

         to the purposes of this Condition:

         (a)      have the same content and format (in relation to each Separate
                  Business) as the annual accounts of the Licensee prepared
                  under Section 226 and, where appropriate, Section 227 of the
                  Companies Act 1985 and conform to the best commercial

         (b)      state the accounting policies adopted; and

         (c)      (with the exception of the part of such statement which shows
                  separately the amounts charged, apportioned or allocated and
                  describes the bases of charge or apportionment or allocation
                  respectively and with the exception of the accounting
                  statements relating to the Second-Tier Supply Business), be

7.       Unless the accounting statements prepared under sub-paragraph (b) (i)
         of paragraph 3 are prepared on the current cost basis as provided by
         the alternative accounting rules, the Licensee shall, unless otherwise
         agreed by the Director, in addition to preparing those accounting
         statements under that paragraph, prepare accounting statements for each
         Separate Business covering the same period, which shall comprise and
         show separately:

                  source and application of funds, together with notes thereto,
                  which shall:

                  (i)      include in respect of current cost assets amounts
                           determined on the current cost basis as provided by
                           the alternative accounting rules; and
                           

                                       22

 
                  (ii)     show or disclose the information and other matters

                           included in respect of assets covered by any items
                           shown in those accounts have been determined on any
                           basis mentioned in paragraph 31 of Section C of Part
                           II of Schedule 4 to the Companies Act 1985;

         (b)      in respect of each Separate Business the adjusted amount of
                  any such provision for depreciation as is referred to in
                  paragraph 32 (2) of Section C of Part II of Schedule 4 to the
                  Companies Act 1985 and the items shown in the profit and loss
                  account of the Separate Business for the relevant period which

                  cost basis as provided by the alternative accounting rules,
                  including the profit (or loss) before taxation; and

         (c)      such other current cost information as is referred to in the
                  Handbook as the Director may reasonably require

         and shall deliver the same, together with the Auditors' report prepared

         referred to in sub-paragraph (c) of paragraph 3, to the Director within
         the time limit referred to in sub-paragraph (d) of paragraph 3, and

         separately the amounts charged, apportioned or allocated and describes
         the bases of charge or apportionment or allocation respectively and
         with the exception of the accounting statements relating to the Second-
         Tier Supply Business) publish the same with the annual accounts of the
         Licensee.

8.       References in this Condition to costs or liabilities of, or reasonably
         attributable to, any Separate Business shall be construed as excluding
         taxation, capital liabilities which do not relate principally to a
         particular Separate Business, and interest thereon; and references to
         any profit and loss account shall be construed accordingly.

         Companies Act 1989 are not in force at the date of grant of this
         Licence shall be construed as if such provisions were in force at such
         date.

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 on 30 June 1997 and 30 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

         (c)  "In the opinion of the directors of the Licensee, the Licensee
              will not have available to it 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."

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 no longer to 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 Licence. Such
         undertaking shall be obtained by 22 December 1997 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.

                                       28

 
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

         (b)      inform the Director immediately in writing if the directors of
                  the Licensee become aware that the undertaking has ceased to
                  be legally enforceable or that its terms have been breached.

CONDITION 3A:  RESTRICTION 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/)
                        -----------------------------------------------

                    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 Cdt only) for each relevant year, given in the
                    table appearing under that term in the part of Annex A to

                    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 from 1 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
                    distribution losses in respect of the twelve-month period
                    from 1 April 1989 shall be derived by applying the initial

7.1  Without prejudice to Condition 3F, in the case of any tariff described in
     column 2 of the 

                                       51

 
     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 Table
          by the same proportion as the standing charge and the unit charge at
          the beginning of the ninth relevant year of the nearest equivalent
          domestic tariff (not being a prepayment tariff) are lower than the
          standing charge and unit charge respectively of that nearest
          equivalent domestic charge shown against them in column 5 of the Table
          (and in this sub-paragraph the standing charge shall be exclusive of
          any prepayment surcharge); and

     (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)
     shall be multiplied by the following factor:

                         100 + F/t/

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 the 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
      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

           (i)  to reflect what the regulated supply revenue would have been if
           the tariffs in force on 1 August 1997 had remained unchanged until
           the end of the eighth relevant year; and

           (ii) by adding any rebates or discounts to Regulated Customers in
           respect of the period from 1 August 1997 to the end of the eighth
           relevant year, being rebates or discounts not included in the tariffs
           in force on 1 August 1997;

      (b)  to any representations made by the Licensee; and

      (c)  to the cost to the Licensee of changing any tariff.

11.1  Where, for relevant year t, the terms TAdt or GAdt (or both of them) in
      paragraph 4 of Condition 3A have a value greater than 0, the Director may
      give a direction to the Licensee stipulating the prices to be charged, in
      that or any subsequent relevant year, for any (or all) of the tariffs
      described in column 2 of the Table.

11.2  Before giving any such direction, the Director shall consult the Licensee.

                                       53

 
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;

       (b)   to any representation made by the Licensee; and

       (c)   to the cost to the Licensee of changing any tariff.

12.1   Without prejudice to paragraph 9 and Condition 3F, for the tenth and
       every subsequent relevant year, unless the Director has consented in
       writing, each component of each tariff described in column 2 of the Table
       or approved for the purpose of paragraph 2 shall have a price no greater
       than the price at the end of the immediately preceding relevant year, in
       each case multiplied by the formula

                        100 + RPIt - Xc                         
                       -----------------
                             100

       where X/c/ has the value of 3 for the tenth relevant year and the value
       of 0 for every subsequent relevant year.

12.2   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.

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.

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 thereon at a rate 4 per cent above the
     average specified rate, during the ninth relevant year to all 0.1MW
     customers supplied by the 

                                       62

 
     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.

                                       63

 
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.

                                       64

 
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.

6.   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.

7.   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 terms referred to in paragraph 9.

8.   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) the amounts shown in respect of each
          of those specified items are in accordance with the Licensee's
          accounting records which have been maintained in respect of each of
          the relevant Separate Businesses in accordance with Condition 2; and

                                       65

 
     (b)  certified by a director of the Licensee on behalf of the Licensee that
          to the best of his knowledge, information and belief having made all
          reasonable enquiries:

          (i)    there is no amount included in its calculations under Condition

     revised statement in respect of such of the specified items as may be

                                       68

 
CONDITION 3F:  ALLOWANCES 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 Supply Business and
            its Second-Tier Supply Business respectively are recovered by
            appropriate equitable increases in the charges made by the Licensee
            in those Businesses and the Licensee shall comply with the terms of
            any directions so issued.

                                       69

 
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
     forgone 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 insofar 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.

                                       70

 
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

     (b)   the aggregate amounts charged under paragraph 6 on account of the
           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.

11.  In this Condition:

     "allowed security      shall have the meaning ascribed to that term in the
      cost"                 Fuel Security Code;

                                       71

 
     "security period"      means a period commencing on the date on which any
                            direction issued by the Secretary of State under
                            Section 34 (4) (b) of the Act enters into effect and
                            terminating on the date (being not earlier than the
                            date such direction, as varied, is revoked or
                            expires) as the Director, after consultation with
                            such persons (including without limitation, Licence
                            holders liable to be principally affected) as he
                            shall consider appropriate, may with the consent of
                            the Secretary of State by notice to all Licence
                            holders determine after having regard to the views
                            of such persons.

                                       72

 
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
          by the Licensee in accordance with either paragraph 4 or paragraph 5.

2.   A disapplication request pursuant to this Condition 3G shall (a) be in
     writing addressed to the Director, (b) specify the charge restriction
     conditions (or any part or parts thereof) to which the request relates and
     (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

     (b)  in the case of distribution charges regulated under Condition 3A, 31st
          March 2000; or

     (c)  in the case of supply charges regulated under Condition 3B, 31st March
          2000.

                                       73

 
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 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
     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.

5.   If the Monopolies Commission makes a report on a reference made by the
     Director relating to the modification of the 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 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 charge restriction conditions with effect from the disapplication date
     or later.

6.   A disapplication request or notice served under this Condition may be
     served in respect of a specified geographic area.

                                       74

 
CONDITION 4:   PROHIBITION OF CROSS-SUBSIDIES AND OF DISCRIMINATION IN
- ----------------------------------------------------------------------
ELECTRICITY SALE CONTRACTS
- --------------------------


1.   The Licensee shall procure that no Separate Business gives any cross-
     subsidy to, or receives any cross-subsidy from, any other business of the
     Licensee or an affiliate or related undertaking of the Licensee (whether or
     not a Separate Business).

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
     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
     duration of the relevant agreements.

3.   For the purposes of paragraph 2:

     "relevant purchaser"               means any purchaser of electricity from
                                        the Licensee or any affiliate or related
                                        undertaking of the Licensee under an
                                        electricity purchase contract.

                                       75

 
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.

                                       76

 
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.

                                       77

 
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;

     (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:

                                       78

 
     (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

                                       79

 
     (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:

     "Interested Persons"          means all Electricity Suppliers which supply
                                   electricity within the market or area or to
                                   the class of customers in question, the
                                   Relevant Consumers' Committee and such other
                                   persons or bodies as in the opinion of the
                                   Director have a legitimate interest in the
                                   terms on which the Licensee supplies
                                   electricity.

     "terms"                       means all the terms on which a supply of
                                   electricity is offered or provided which
                                   significantly affect the evaluation of that
                                   supply, and shall include all terms as to
                                   price.

                                       80

 
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.

                                       81

 
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
     notice.

                                       82

 
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 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 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 it 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.

                                       83

 
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 Licence
          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 Licence 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.

                                       84

 
8.   In this Condition:

     "defined undertaking"    means Non-Fossil Purchasing Agency Limited or
                              other entity through which the Licensee enters
                              into qualifying arrangements within the meaning of
                              Section 33 of the Act.

     "purchase"               includes the acquisition of electricity from
                              sources falling to be treated as own-generation
                              for the purpose of Condition 6, and the purchase
                              of electricity under electricity purchases
                              contracts.
           
     "qualifying non-fossil   shall include generation from renewable sources
     generation"              which for the time being has not been contracted
                              as being qualifying renewable generation.

                                       85

 
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 amount 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 800 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:

     (a)  the whole of the declared net capacity represented by own-generation
          sets; and

     (b)  the appropriate share (namely the share representing the Licensee's
          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
          determine.

5.   Where the Director is satisfied that by virtue of the Licensee's economic
     interest (ascertained in such manner as the Director may determine)
     therein:

     (a)  generation sets in which the Licensee has only an accountable interest
          should more properly be treated as own-generation sets; or

                                       86

 
     (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 that effect.

6.   For the purposes of this Condition and subject to paragraphs 5 and 9, the
     Licensee shall have an accountable interest in a generation set in
     circumstances where (such generation set not being an own-generation set of
     the Licensee):

     (a)  the operator is a related undertaking of the Licensee or any affiliate
          of the Licensee; or

     (b)  the Licensee or any affiliate of the Licensee is in partnership with
          or is party to any arrangement for sharing profits or cost-savings or
          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):

          (i)    any beneficial shareholding interest in the operator; or

          (ii)   any beneficial underlying interest in the generation set; or

          (iii)  provided or agreed to provide finance to the operator otherwise
                 than on arm's length terms; or

          (iv)   provided or agreed to provide, or has determined or is
                 responsible for determining the price (or other terms affecting
                 the financial value) of, the fuel used in the generation sets;

                                       87

 
                 and is entitled under a contract of not less than 5 years'
                 duration:

                 (aa)  to a share of the declared net capacity of the generation
                       set; or

                 (bb)  to a share of the declared net capacity of a generation
                       set 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 electricity representing such entitlement
                       between the licensee or its affiliate and such Authorised
                       Electricity Operator.

7.   Paragraph 6 shall be applied in relation to the calculation of an
     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.

9.   The Licensee shall not be deemed to have an accountable interest in a
     generation set where:

     (a)  such generation set is owned and operated by the National Grid Company
          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
          the sharing with the operator of any generation set of the risks
          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.

                                       88

 
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

     (b)  identifying (in such detail and with such supporting documents or
          information as the Director may require) the amount of capacity in
          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.

11.  Where the Director is satisfied that the basis of calculation used by the
     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
     be specified in the directions.

12.  In this Condition:

     "operator"                 means, in relation to any generation set, the

                                or otherwise) for the generation or sale of
                                electricity from such plant.

     "own-generation set"       means any generation set the majority beneficial

                                an affiliate of the Licensee or in respect of
                                which the Licensee or an affiliate of the
                                Licensee is the operator and references to own-
                                generation sets of another Authorised
                                Electricity Operator shall be construed as if
                                the reference herein to the Licensee were
                                replaced by reference to that Authorised
                                Electricity Operator.

                                      not be deemed to be operated as a unit
                                      with any generation set by reason only of

     (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.

                                       91

     (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.

     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.

                                       92

     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;

          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;

                                       93

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

                                       96

 
     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;

          Licensee or any third party; and

     (b)  omit information the disclosure of which would place the Licensee in
          breach of Condition 12.

     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.

          making the request to pay the amount estimated or such other amount as
          is determined by the Director (as the case may be) under paragraph 16.

18.  The Licensee shall, not less than 5 months prior to the date on which it
     proposes to amend its use of system charges in respect of any agreement for
     use of system, send to the Director a notice setting out the Licensee's

     any person who has entered into an agreement for use of system under
     Condition 8B. 

                                      103

 
19.  Except with the prior consent of the Director, the Licensee shall not amend
     its use of system charges in respect of any agreement for use of system
     save to the extent that it has given prior notice of the amendment in
     accordance with paragraph 18 and such amendment reflects the proposals made
     in the notice (subject only to revisions consequent upon material changes
     in the matters which were expressed, in the statement which accompanied the
     notice, to be assumptions on which the proposals were based).

5.   For the purpose of determining an appropriate proportion of the costs

          additional entry or exit points on such system or otherwise;

     (b)  the ability or likely future ability of the Licensee to recoup a

     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 if:

     (a)  to do so would be likely to involve the Licensee being:

          i)   in breach of its duties under section 9 of the Act;

          ii)  in breach of the Electricity Supply Regulations 1988 or of any
               regulations made under section 29 of the Act or of any other

          iv)  in breach of the Conditions;

     (b)  the person making the application does not undertake to be bound,     
          in so far as applicable, by the terms of the Distribution Code or     
          the Grid Code from time to time in force;                             
                                                                                
     (c)  in the case of a person making application for use of system          
          under paragraph 1, such person ceases to be an Authorised             
          Electricity Operator; or                                              
                                                                                
     (d)  in the case of a person making application for exempt supply          
          services under paragraph 4, such person ceases to be an Exempt        
          Supplier.  

8.   For the purpose of paragraph 6, the period specified shall be:

     (a)  in the case of persons seeking use of system, exempt supply services
          or top-up or standby supplies or sales of electricity only, 28 days;

     (c)  in the case of persons seeking use of system or top-up or standby
          supplies or sales of electricity in conjunction with connection, 3
          months.

9.   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
     in any further regulations then in force made pursuant to sections 6(3), 60
     and 64(1) of the Act.

                                      113

 
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.

                                      114

 
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.

                                      115

 
CONDITION 8D:   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 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
     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 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 6 of Condition 8;

          ii)  in the case of exempt supply services, such sum as is determined
               in accordance with paragraph 7 of Condition 8;

          iii) in the case of provision of use of system, the use of system
               charges determined in accordance with paragraph 8 of Condition 8;
               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 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;
 

                                      116

 
         (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 an application under Condition 8B or 8C
                  should be, so far 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.

                                      117

         Chief Engineers' Conference in so far as applicable to it or such other
         standard of planning as the Licensee may, following consultation (where
         appropriate) with the Transmission Company and any other Authorised
         Electricity Operator liable to be materially affected thereby and with
         the approval of the Director, adopt from time to time.

2.       The Licensee shall within 3 months after this Licence enters into force
         draw up and submit to the Director for his approval a statement setting
         out criteria by which the quality of performance of the Licensee in
         maintaining distribution system security and availability and quality
         of service may be measured.

3.       The Licensee shall within 2 months after the end of each financial year
         submit to the Director a report providing details of the performance of
         the Licensee during the previous financial year against the criteria
         referred to in paragraph 2.

4.       The Director may (following consultation with the Licensee and, where
         appropriate, with the Transmission Company and any other Authorised
         Electricity Operator liable to be materially affected thereby) issue
         directions relieving the Licensee of its obligation under paragraph 1
         in respect of such parts of the Licensee's Distribution System and to
         such extent as may be specified in the directions.

                                      118

                  authorised area; or

         (b)      affects or is likely to affect the maintenance of the

3.       In the establishment and operation of the enquiry service in accordance
         with paragraph 1 the Licensee shall not discriminate:

         (a)      between any persons or class or classes thereof; or

         (b)      between the Licensee (in the provision of such services by the
                  Licensee as part of its Distribution Business to itself for
                  the purpose of its Supply Business) and any private
                  electricity supplier or any customer thereof.

                                      119

 
4.       In the establishment and operation of the enquiry service in accordance
         with paragraph 1 the Licensee shall not restrict, distort or prevent
         competition in the supply of electricity.

5.       The Licensee shall by 1 January 1998 prepare and submit to the Director
         for his approval a statement setting out details of the service to be
         provided in accordance with paragraph 1, and the Licensee shall,
         following the Director's approval, give or send a copy of such
         statement to any person requesting it.

6.       The Licensee shall give to the Director notice of any amendments it
         proposes to make to the statement prepared under paragraph 5, and shall
         not make such amendments until either:

         (a)      a period of one month from the date of the notice has expired;
                  or

         (b)      prior to the expiry of such period, the Licensee has obtained
                  the written approval of the Director to the amendments.

7.       The Licensee shall make arrangements to keep each of its customers
         informed of a postal address and telephone number at which the service
         established in accordance with paragraph 1 may be contacted.

8.       The Licensee may discharge the duty imposed by paragraph 7 by providing
         the requisite information to each of its customers:

         (a)      on the occasion of the customer first commencing to take a
                  supply from the Licensee; and

         (b)      either:

                  (i)    where bills or statements in respect of charges for the
                         supply of electricity are rendered to the customer, on
                         a quarterly basis (it being sufficient that the
                         information is included on or with any bill or
                         statement); or

                  (ii)   where no bills or statements in respect of charges for
                         the supply of electricity are rendered to the customer,
                         on an annual basis

         and by publishing such information in such manner as will in the
opinion of the Licensee secure adequate publicity for it.

                                      120

 
9.       The Licensee shall take steps to inform each of its customers, and each
         Authorised Electricity Operator which uses the service, of any change
         to the address or telephone number of the service established in
         accordance with paragraph 1 as soon as is practicable prior to such
         change becoming effective.

                                      121

 
CONDITION 9B:     PROCEDURES FOR THE DETECTION AND PREVENTION OF THEFT, DAMAGE
- ------------------------------------------------------------------------------
AND METER INTERFERENCE
- ----------------------

1.       The Licensee shall (and shall ensure that its agents) take all
         reasonable steps to detect and prevent:

         (a)      the theft of electricity at premises which are supplied by it;

         (b)      damage to any electrical plant, electric line or electricity
                  meter through which such premises are supplied; and

         (c)      interference with any electricity meter through which such
                  premises are supplied.

2.       Where a person other than the Licensee is the owner of any electrical
         plant, electric lines or meter the Licensee shall, as soon as is
         reasonably practicable, inform that person of any incident where it has
         reason to believe:

         (a)      there has been damage to such electrical plant, electric line
                  or meter; or

         (b)      there has been interference with the meter to alter its
                  register or prevent it from duly registering the quantity of
                  electricity supplied.

3.       Where a person other than the Licensee is the supplier of electricity
         to premises within the authorised area the Licensee shall, as soon as
         is reasonably practicable, inform that person of any incident where it
         has reason to believe:

         (a)      there has been damage to any electrical plant, electric line
                  or meter through which such premises are supplied with
                  electricity; or

         (b)      there has been interference with the meter through which such
                  premises are supplied to alter its register or prevent it from
                  duly registering the quantity of electricity supplied.

                                      122

 
CONDITION 9C:     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 effect prior to 1 April 2000; or

         (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 8B.

                                      123

 
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.

                                      124

 
CONDITION 9D:     AGREEMENTS FOR THE PROVISION OF METERS
- --------------------------------------------------------

1.       The Licensee shall not, in the course of its Supply Business, enter
         into an agreement with any person for the provision of an electricity
         meter at any premises (whatever the nature of that agreement) which is
         intended or is likely to restrict, distort or prevent competition in
         the supply of electricity.

                                      125

 
CONDITION 10:     GENERATION SECURITY STANDARD
- ----------------------------------------------

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

2.       The duty imposed by paragraph 1 shall be discharged either by the
         Licensee's complying with the provisions of paragraph 3 below or by the
         making by the Licensee of such other arrangements as may have been
         previously approved in writing for the purpose by the Director.

3.       The Licensee may discharge the duty imposed by paragraph 1 by:

         (a)      for so long as the relevant condition is met, purchasing as a
                  pool member under the terms of the Pooling and Settlement
                  Agreement quantities of electricity which are at all times
                  sufficient to meet the demands of all qualifying customers of
                  the Licensee; and

         (b)      for so long as the relevant condition is met, and save by
                  reason of planned maintenance undertaken on the Licensee's
                  Distribution System or in circumstances of force majeure
                  affecting either the Licensee's Distribution System or the
                  quantities of electricity delivered into that system, not:

                  (i)      making voltage reductions outside statutory limits;
                           or

                  (ii)     interrupting or reducing supplies to any qualifying
                           customer

         otherwise than as instructed pursuant to the Grid Code by the
         Transmission Company or in accordance with the Distribution Code.

4.       The relevant condition referred to in paragraph 3 is that there should
         at any relevant time be electricity available to be purchased under the
         terms of the Pooling and Settlement Agreement at a price less than the
         ceiling price.

                                      126

 
5.       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.

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

7.       In this Condition:

         "ceiling price"            means such price as would be equal to the
                                    Pool Selling Price in circumstances where
                                    the corresponding Pool Purchase Price was an
                                    amount equal to the Value of Lost Load.

         "generation security       means such standard of generation security 
          standard"                 as will ensure that:

                                    (a)     the supply of electricity to
                                            qualifying customers will not be
                                            discontinued in more than 9 years in
                                            any 100 years; and

                                    (b)     the voltage or frequency of
                                            electricity supplied to qualifying
                                            customers will not be reduced below
                                            usual operational limits in more
                                            than 30 years in any 100 years by
                                            reason of insufficiency of
                                            electricity generation available for
                                            the purposes of supply by the
                                            Licensee to its qualifying customers
                                            at times of annual system peak
                                            demand.

         "Pool Purchase Price"      shall each have the meaning from time to
          and "Pool Selling         time ascribed to them in Schedule 9 to the
          Price"                    Pooling and Settlement Agreement.

         "qualifying customer"      means any purchaser from the Licensee
                                    entitled and requiring at any time to be
                                    supplied by the Licensee at premises within
                                    the authorised area of the Licensee but
                                    shall exclude:

                                    (a)     a contract purchaser under an
                                            interruptible contract or a contract
                                            containing load management terms to
                                            the extent that supplies to that
                                            purchaser may be interrupted or
                                            reduced in accordance with the terms
                                            of that contract; and

                                    (b)     a tariff customer on special tariffs
                                            which restrict supplies to
                                            particular time periods to the
                                            extent that supplies to that
                                            customer may be interrupted or
                                            reduced in accordance with such
                                            tariff.

         "Value of Lost Load"       means in respect of the first financial
                                    year, the sum of (pound)2 per kWh and, in
                                    respect of each succeeding financial year,
                                    the sum which corresponds to (pound)2 per
                                    kWh as adjusted to reflect the percentage
                                    change in the Retail Price Index between the
                                    index published or determined in respect to
                                    the December prior to the start of that
                                    financial year and the index published or
                                    determined for December 1989.

CONDITION 11:     DISTRIBUTION CODE
- -----------------------------------

1.       The Licensee shall in consultation with Authorised Electricity
         Operators liable to be materially affected thereby prepare and at all
         times have in force and shall implement and (subject to paragraph 10 of
         this Condition) comply with a Distribution Code:

         (a)      covering all material technical aspects relating to
                  connections to and the operation and use of the Licensee's
                  Distribution System or (insofar as relevant to the operation
                  and use of the Licensee's Distribution System) the operation
                  of electric lines and electrical plant connected to the
                  Licensee's Distribution System or the distribution system of
                  any Authorised Electricity Operator and (without prejudice to
                  the foregoing) making express provision as to the matters
                  referred to in paragraph 5 below; 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 distribution of electricity; and

                  (ii)     to facilitate competition in the generation and
                           supply of electricity.

2.       The Distribution Code in force at the date this Licence enters force
         shall be sent to the Director for his approval. Thereafter the Licensee
         shall (in consultation with Authorised Electricity Operators liable to
         be materially affected thereby) periodically review (including upon the
         request of the Director) the Distribution Code and its implementation.
         Following any such review, the Licensee shall send to the Director:

         (a)      a report on the outcome of such review; and

         (b)      any proposed revisions to the Distribution Code from time to
                  time as the Licensee (having regard to the outcome of such
                  review) reasonably thinks fit for the achievement of the
                  objectives referred to in sub-paragraph (b) of paragraph 1;
                  and

                                      129

 
         (c)      any written representations or objections from Authorised
                  Electricity Operators (including any proposals by such
                  operators for revisions to the Distribution Code not accepted
                  by the Licensee in 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 Director.

4.       Having regard to any written representations or objections referred to
         in 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

          and Data Services will be made; and

     (b)  information relating to the other terms that will apply to the
          provision of each service,

in each case in such form and with such detail as shall be necessary to enable
     any person to make a reasonable estimate of the charges to which he 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 foregoing)
     including the information set out in paragraph 2.

2.   The statements referred to in paragraph 1 shall include:

     (a)  a schedule of charges for such services; and

     (b)  an explanation of the methods by which and the principles on which
          such charges will be calculated.

3.   The Director may, upon the written request of the Licensee, issue a
     direction relieving the Licensee of its obligations under paragraphs 1 and
     2 to such extent and subject to such terms and conditions as he may specify
     in that direction.

4.   The Licensee shall not in setting its charges for or in setting the other
     terms that will apply to the provision of any of the Metering and Data
     Services restrict, distort or prevent competition in the generation,
     distribution or supply of electricity or in the provision of meter
     operation, data retrieval, data processing or data aggregation services.

                                      142

     in order that the information set out in the statements shall continue to
     be accurate in all material respects.

8.   The Licensee may make a charge for any statement given or sent pursuant to
     paragraph 7 of an amount which shall not exceed the amount specified in

CONDITION 11F:   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 11C, 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 11E;

     (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; 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 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.

4.   The Director may (following consultation with the Licensee) issue
     directions relieving the Licensee of its obligations under Condition 11C in
     respect of such parts of that Condition and to such extent as may be
     specified in the directions.

                              legal or beneficial interest in land upon which
                              any of the foregoing is situate.

1.   Subject to paragraphs 6 and 7, the Licensee shall furnish to the Director,
     in such manner and at such times as the Director may require, such
     information and shall procure and furnish to him such reports, as the
     Director may consider necessary in the light of the Conditions or as he may
     require for the purpose of performing:

     (a)  the functions assigned to him by or under the Act; and

     (b)  any functions transferred to him under the Act.

2.   The Licensee shall by 22 December 1997 procure from the holding company of
     the Licensee a legally enforceable undertaking in favour of the Licensee in

     that the holding company will give to the Licensee, and will procure that
     each subsidiary of that holding company (other than the Licensee and its
     subsidiaries) will give to the Licensee, all such information as may be
     necessary to enable the Licensee to comply fully with paragraph 1. Such
     undertaking 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.

     such undertaking) that the Licensee has complied with the obligation to
     procure an undertaking pursuant to paragraph 2.

     enter (directly or indirectly) into any agreement or arrangement with the
     holding company of the Licensee or any of the subsidiaries of the holding
     company (other than the subsidiaries of the Licensee) at a time when:

     (a)  an undertaking complying with paragraph 2 is not in place; or

     (b)  there is an unremedied breach of such undertaking.

5.   Without prejudice to the generality of paragraph 1, the Director may call

     under Condition 2.

                                      179

 
6.   The Licensee may not be required by the Director to furnish him under this
     Condition with information for the purpose of the exercise of his functions
     under Section 48 of the Act.

     Condition with any information in relation to an enforcement matter which
     the Licensee could not be compelled to produce or give under Section 28(3)
     of the Act.

8.   The power of the Director to call for information under paragraph 1 is in
     addition to the power of the Director to call for information under or
     pursuant to any other Condition.

9.   The Licensee shall, if so requested by the Director, give reasoned comments
     on the accuracy and text of any information and advice (so far as relating

1.   The Licensee shall, at the times stated hereunder, pay to the Secretary of
     State fees of the amount specified in, or determined under, this Condition.

2.   In respect of the year beginning on 1 April 1991 and in each subsequent
     year, the Licensee shall pay to the Secretary of State a fee which is the
     aggregate of the following amounts:

     (a)  an amount which is a proportion as determined by the Director of the
          amount estimated by the Director, according to a method which has
          previously been disclosed in writing to the Licensee, as likely to be
          his total costs during the coming year;

     (b)  the amount (or, where the Relevant Consumers' Committee in question is
          the consumers' committee for more than one public electricity
          supplier, the amount which is a proportion as determined by the
          Director, according to a method which has previously been disclosed in
          writing to the Licensee, of such amount) estimated by the Director
          (having regard to any statement under paragraph 8(2) of Schedule 2 to
          the Act) as being likely to be the costs during the coming year of the
          Relevant Consumers' Committee in the exercise of the functions
          assigned to it by or under the Act and any other such functions as it
          has been or may be required to exercise by the Director;

     (c)  an amount which is a proportion as determined by the Director of the
          amount estimated by the Director (in consultation with the Monopolies
          Commission) as having been incurred in the calendar year immediately
          preceding the 1st April in question by the Monopolies Commission in
          connection with references made to it under Section 12 of the Act with
          respect to this Licence or any other licence issued under Section

     (d)  the difference (being a positive or a negative amount), if any,
          between:

          (i)  the amount of the fee paid by the Licensee in respect of the year
               immediately preceding the 1st April in question; and

          (ii) the amount which that fee would have been in respect of that year
               had the amounts comprised therein been calculated by reference
               to:

                                      181

 
                    (aa) in the case of sub-paragraph 2(a), the actual total
                         costs of the Director during that year and the
                         proportion thereof attributable to the Licensee; and

                    (bb) in the case of sub-paragraph 2(b), the actual total
                         costs of the Relevant Consumers' Committee during that
                         year and where appropriate, the proportion thereof
                         attributable to the Licensee,

                    (such costs being apportioned in each case as determined by
                    the Director according to a method previously disclosed in
                    writing to the Licensee),

     and the fee shall be paid by the Licensee to the Secretary of State within
one month of the Director giving notice to the Licensee of its amount if that
notice is given within 6 months of the beginning of the year in respect of which
the fee is payable.

                                      182

 
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 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.

                                      183

 
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.  
                                        

                                      184

 
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
     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.

                                      185

 
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.

                                      186

 
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 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;

     (c)  a statement of his reasons for proposing those revisions; and

                                      187

 
     (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:

                                 C  x 100
                                --- 
                                C+N

     where:

          C =  the number of consenting Electricity Suppliers; and

          N =  the number of non-consenting Electricity Suppliers.

                                      188

 
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.

11.  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 Contract Terms Conditions.

                                      189

 
                   PART III - THE CONTRACT TERMS CONDITIONS
                   ----------------------------------------


CONDITION 34:     DESIGNATED SUPPLY CONTRACTS
- ---------------------------------------------

1.   A Designated Supply Contract is a contract for the supply of electricity to
     Designated Premises, as varied from time to time, which complies with the
     provisions of this Condition.

2.   Without prejudice to its rights and obligations under the Act, the Licensee
     shall not supply electricity to Designated Premises on contract except
     under a Designated Supply Contract.

     and 39.

4.   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.

5.   Where a Designated Supply Contract may be terminated by a customer by
     virtue of any provision included in that contract in compliance with
     Conditions 38 and 39, the Licensee may at its discretion accept a lesser
     period of notice than is specified in that provision.

6.   Nothing in this Licence shall prevent the Licensee from entering into a
     Designated Supply Contract which contains provisions for its termination
     that are additional to and do not derogate from those set out at Conditions
     38 and 39.

                                      192

 
CONDITION 35:  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.

                                      191

 
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.

                                      192

 
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

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.

                                      193

 
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.

                                      194

 
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.

                                      195

 
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.

                                      196

 
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:

     (a)  the contract was terminated under any provision of Condition 39;

                                      197

 
     (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.

                                      198

 
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

     (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.

                                      199

 
     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.

                                      200

 
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;

     (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

     (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 

                                      201

 
          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.

                                      202

 
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).

                                      203

 
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.

                                      204

1.   The Secretary of State may at any time revoke this Licence by not less than
     30 days' notice in writing to the Licensee:

     (a)  if the Licensee agrees in writing with the Secretary of State that

     (b)  if any amount payable under Condition 29 is unpaid 30 days after it
          has become due and remains unpaid for a period of 14 days after the

          overdue. Provided that no such notice shall be given earlier than the
          sixteenth day after the day on which the amount payable became due;

          and (in either case) such failure is not rectified to the satisfaction
          of the Secretary of State within 3 months after the Secretary of State
          has given notice of such failure to the Licensee. Provided that no
          such notice shall be given by the Secretary of State before the
          expiration of the period within which an application under Section 27
          of the Act could be made questioning the validity of the final or
          provisional order or before the proceedings relating to any such

                 (1) or (2) of the Insolvency Act 1986, but subject to paragraph

                 period as may previously have been approved in writing by the
                 Secretary of State);

          (ii)   has a receiver (which expression shall include an
                 administrative receiver within the meaning of Section 29 of the

          (v)    becomes subject to an order by the High Court for winding-up;
                 or

     (g)  if the Licensee is convicted of having committed an offence under

2.   (a)  For the purposes of paragraph 1 (f) (i) of this Schedule Section 123
          (1) (a) of the Insolvency Act 1986 shall have effect as if for
          "(pound)750" there was substituted "(pound)250,000" or such higher
          figure as the Director may from time to time determine by notice in
          writing to the Secretary of State and the Licensee.

          is mentioned in Section 123 (1) (a) of the Insolvency Act 1986 is
          being contested in good faith by the Licensee with recourse to all
          appropriate measures and procedures or if any such demand is satisfied

          given by the Secretary of State under paragraph 1 of this Schedule.

3.   The provisions of Section 109 of the Act shall apply for the purposes of

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


     General Principles
     ------------------

A1.  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 A1.

     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:

                                      209

 
          (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 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 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.

                                      210

 
     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
     statement referred to at paragraph 7 of Condition 3E, a statement of 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 therefor.

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 A1, 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.

                                      211

 
                                    PART B
                                    ------

                                 EHV PREMISES
                                 ------------

B1.  EHV premises shall comprise:

     (a)  in relation to premises connected to the Licensee's distribution
          system as at the date this Licence enters into force, those premises
          specified in the list of EHV premises notified in writing to the
          Director by the Licensee within twenty-eight days after this Licence
          enters into force; and

     (b)  in relation to premises connected to the Licensee's distribution
          system which are either first connected or (having been previously
          connected) have had their connections materially altered following the
          date this Licence enters into force, means premises connected to the
          Licensee's distribution system at a voltage at or higher than 22
          kilovolts or at a sub-station with a primary voltage of 66 kilovolts
          or above.

B2.  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 listing
     any changes in the premises falling to be treated as EHV premises.

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.

                                      212

 
                                    PART C
                                    ------

                               EXCLUDED SERVICES
                               -----------------


     Distribution Business
     ---------------------

C1.  There may be treated as excluded services provided by the Licensee in its
     Distribution Business such services in respect of which charges are made
     which:

     (a)  do not fall within paragraph C2 of this Part; and

     (b)  may (subject to paragraph C9) be determined by the Licensee as falling
          under one of the principles set out in paragraphs C3 to C6 of this
          Part.

C2.  No service provided by the Licensee as part of its Distribution Business
     shall be treated as an excluded service insofar as it consists of the
     provision of services remunerated under the use of system charges in
     accordance with paragraph 3 of Condition 8 including (without prejudice to
     the foregoing):

          (i)    (subject to paragraph C3 of this Part) the transport of
                 electricity;

          (ii)   the carrying out of works for the installation of electric
                 lines or electrical plant (not otherwise payable in the form of
                 connection charges);

          (iii)  the carrying out of works or the provision of maintenance or
                 repair or other services for the purpose of enabling the
                 Licensee to comply with Conditions 9, 11 and 13, the
                 Electricity Supply Regulations 1988 or any regulations made
                 under Section 29 of the Act or any other enactment relating to
                 safety or standards applicable in respect of the Distribution
                 Business; and

          (iv)   (subject to paragraph C5 of this Part) the provision,
                 installation and maintenance of any meters, switchgear or other
                 electrical plant (not being part of connection charges).

                                      213

 
C3.  The Licensee may treat as being an excluded service for the purposes of its
     Distribution Business the transport of:

     (a)  units of electricity not consumed in the Licensee's authorised area;
          or

     (b)  EHV units.

C4.  Charges of the type described in paragraph 4 of Condition 8 and borne in
     accordance with the principles set out in paragraph 7 of Condition 8 by any
     person as connection charges, and charges in respect of the statements
     referred to in paragraph 8 of Condition 8, may each be treated as excluded
     services for the purposes of the Distribution Business.

C5.  A service provided by the Licensee as part of its 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 by the Licensee as a normal part of its Distribution Business
     remunerated by use of system charges including (without prejudice to the
     foregoing):

          (i)    special metering (including "time of day" metering) to
                 facilitate energy saving programmes for the benefit of
                 customers requesting the same;

          (ii)   charges for moving mains, services or meters forming part of
                 the Licensee's distribution system to accommodate extension, 
                 re-design or re-development of any premises on which the same
                 are located or to which they are connected;

          (iii)  the provision of electric lines and electrical plant (a)
                 insofar as the same are required for the specific purpose of
                 enabling the provision of top-up or standby supplies or sales
                 of electricity or (b) to provide a higher degree of security
                 than is required for the purposes of complying with Condition
                 9;

                                      214

 
          (iv)   the amount by which charges for the provision of prepayment
                 meters to customers exceed charges for the provision of
                 standard meters for such customers; and

          (v)    special metering or telemetry or data processing equipment for
                 the purpose of enabling any person who is a party to the
                 Pooling and Settlement Agreement to comply with its obligations
                 in respect of metering thereunder, or for the performance by
                 the Licensee of any service in relation thereto.

C6.  There may be treated as an excluded service for the purposes of the
     Distribution Business, charges for the relocation of electric lines or
     electrical plant and the carrying out of works associated therewith
     pursuant to a statutory obligation (other than under Section 9 (1) or
     Section 16 of the Act) imposed on the Licensee.

     Supply Business
     ---------------

C7.  Subject to paragraph C9, a service provided by the Licensee as part of its
     Supply Business may be treated as an excluded service insofar as it
     consists of the provision of services for the specific benefit of customers
     requesting the same and not made available by the Licensee as a normal part
     of such Business. For the avoidance of doubt, the provision of facilities
     for prepayment may not be treated as an excluded service except the
     provision of prepayment meters as an excluded service by the Distribution
     Business.

     Information to be provided to the Director
     ------------------------------------------

C8.  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, details specifying
     separately the nature of all services provided as part of its Distribution
     Business or Supply Business by the Licensee and treated as excluded
     services by the Licensee during the course of such year and stating the
     revenues derived by the Licensee in respect of each such service so
     treated.

                                      215

 
     Directions
     ----------

C9.  Where the Director is satisfied that in light of the principles set out in
     paragraphs C2 to C7 inclusive any service treated by the Licensee as an
     excluded service should not be so treated, the Director shall issue
     directions to that effect, and the service or services specified in the
     directions shall cease to be treated as excluded services 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.

                                      216

 
                                    PART D
                                    ------

                    REGULATED DISTRIBUTION UNIT CATEGORIES
                    --------------------------------------

D1.  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, details specifying
     separately those use of system charges in respect of which the Licensee has
     during the course of such year treated the units distributed as falling
     within the definition of each of LV1 units and LV2 units and LV3 units
     respectively.

D2.  The definition of LV1 units includes units distributed under the following
     tariffs:

          Domestic E7 day rate
          Quarterly non domestic E7 day rate
          Quarterly non domestic 3-rate evening, weekend and night tariff: day,
          evening and weekend units only.

D3.  The definition of LV2 units includes units distributed under the following
     tariffs:

          Domestic E7 night rate
          Quarterly non domestic E7 night rate
          Quarterly non domestic 3-rate evening, weekend and night tariff: night
          units only
          Off peak tariffs.

D4.  The definition of LV3 units includes units distributed under the following
     tariffs:

          General domestic
          Quarterly unrestricted non domestic
          Quarterly non domestic two-rate evening and weekend tariffs
          Monthly billed maximum demand tariffs 
          STOD tariffs 
          Public lighting.

                                      217

 
D5.  Notwithstanding the provisions of paragraphs D2 to D4 above, where the
     Director is satisfied that a tariff or tariffs in respect of which the
     Licensee has treated the units distributed as falling within one of the
     categories in paragraphs D2 to D4 above should not be so treated, the
     Director shall issue directions to that effect and the tariff or tariffs
     specified in the directions shall cease to be so treated 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 and shall with effect from
     such date be treated in such manner as may be specified in the directions.

                                      218

 
                                    PART E
                                    ------

            CALCULATION OF FACTOR IN RESPECT OF DISTRIBUTION LOSSES
            -------------------------------------------------------

E1.  For the purposes of calculation of the terms ALt and Lt as used in
     paragraph 1 of Condition 3A shall each be determined for relevant years
     commencing on or after 1st April 1995 using the consistent methodological
     basis set out in paragraphs E2 to E5 below.

     Consistent methodological basis for determination of  ALt and L
     ---------------------------------------------------------------

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

                                      219

 
     (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 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 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 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 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.

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

     (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).

                                      220

 
     Initial relevant loss percentage in the term ALt
     ------------------------------------------------

E6.  In the first relevant year, the initial relevant loss percentage in the
     term ALt 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

     (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.

                                      221

 
      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.

E11.  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.

                                      222
