Dear Sirs

(pound)200,000,000 7.25 per cent bonds due 2022 Issued by CE Electric UK Funding
- --------------------------------------------------------------------------------
Company and guaranteed by Ambac Assurance UK Limited (the "Bonds")
- ------------------------------------------------------------------

1.   We,  Ambac  Assurance  UK Limited  ("Ambac"),  refer to the trust deed (the
     "TRUST  DEED") dated 15 December 1997  constituting  the Bonds entered into
     between CE Electric UK Funding  Company (the  "ISSUER"),  Ambac and The Law
     Debenture  Trust  Corporation  p.l.c.  (the  "TRUSTEE").  Unless  otherwise
     defined in this  letter or unless the  context  otherwise  requires,  terms
     defined  (expressly  or by  incorporation)  in the Trust Deed have the same
     meanings when used in this letter.

2.   We have been advised by the Issuer that upon completion of the transactions
     contemplated by a share sale agreement  dated 6 August 2001 between,  among
     others,  Innogy  Holdings  plc and CE Electric UK plc and the  arrangements
     connected with such share sale agreement, inter alia:

     2.1  CE Electric UK plc will acquire  94.75% of the issued share capital of
          Yorkshire Power Group Limited ("YPG");


     2.2  Northern  Electric  plc, a  Principal  Subsidiary  of the Issuer  will
          dispose of its electricity  supply and metering  business and Northern
          Electric and Gas Limited will dispose of its gas supply business;

     2.3  thereafter,  upon the  implementation  of a statutory  transfer scheme
          pursuant to the Utilities Act 2000, the PES Licence will be split into
          separate   distribution   and  supply   licences  and  the   resulting
          distribution licence will be vested in Northern Electric  Distribution
          Ltd.  (a  Subsidiary  of  Northern  Electric  plc)  and the  resulting
          electricity supply licence will be vested in Northern Electric and Gas
          2 Limited; and

     2.4  immediately  after  such  implementation,  and in  furtherance  of the
          transactions  described  above,  Northern  Electric  plc will sell its
          entire  interests in Northern  Electric and Gas 2 Limited to an Innogy
          Holdings plc group company.

3.   We have been  advised by the Issuer and agree,  based upon the  information
     that the Issuer has provided to us, that none of the circumstances referred
     to in paragraph 2 above would give rise to a Restructuring  Event under the
     Bonds.  In  particular,  the Issuer's  view is that where,  as described in
     paragraph 2.3 above, a new  distribution  licence will be issued in respect
     of the Group's Distribution Business:

     3.1  the exception in paragraph  (B) of paragraph (i) of the  definition of
          "Restructuring Event" will apply; and

     3.2  the exception in paragraph (a) of paragraph  (ii) of the definition of
          "Restructuring Event" will apply,

     in each case,  even if (as  described in paragraph  2.3 above) a new supply
     licence is also granted.

4.   However, to remove any potential doubt, at the request of the Issuer we, in
     our  capacity as  Controlling  Party,  hereby  exercise the Trust Rights in
     respect of the Bonds and direct  that you, as Trustee  confirm  pursuant to
     Clause 12(K) of the Trust Deed that:

     4.1  with  regard to  paragraph  (i) of the  definition  of  "Restructuring
          Event" and, in particular, the exception contained therein:

          4.1.1     the  circumstances described in paragraph 2.3 above shall be
                    construed as falling exclusively within paragraph (B) of
                    such exception; and

          4.1.2     accordingly  and to the  extent  that  paragraph  (i) of the
                    definition of "Restructuring  Event" applies,  the operative
                    provision  within the  definition of  "Restructuring  Event"
                    relating to the deeming of references to the PES Licence and
                    Northern  Electric plc shall be construed (in the context of
                    the circumstances described in paragraphs 2.3 and 2.4 above)
                    as  only  requiring,  upon  implementation  of the  relevant
                    statutory transfer scheme;


               (A)  references  to the PES Licence to be deemed to be references
                    to  the  distribution  licence  to be  granted  to  Northern
                    Electric  Distribution  Ltd. (being the licence  relating to
                    the Group's Distribution Business); and

               (B)  references  to  Northern  Electric  plc to be  deemed  to be
                    references to Northern Electric Distribution Ltd. (being the
                    Relevant Transferee);

     4.2  with regard to  paragraph  (ii) of the  definition  of  "Restructuring
          Event":

          4.2.1     the circumstances  described in paragraph 2.3 above shall be
                    construed as falling exclusively within sub-paragraph (a) of
                    such paragraph (ii); and

          4.2.2     accordingly  and to the extent  that  paragraph  (ii) of the
                    definition of "Restructuring  Event" applies,  the operative
                    provision  within such paragraph  relating to the deeming of
                    references  to the PES Licence  and  Northern  Electric  plc
                    shall be  construed  (in the  context  of the  circumstances
                    described  in   paragraphs   2.3  and  2.4  above)  as  only
                    requiring,  upon  implementation  of the relevant  statutory
                    transfer scheme:

                    (A)  references  to  the  PES  Licence  to be  deemed  to be
                         references to the distribution licence to be granted to
                         Northern Electric  Distribution Ltd. (being the licence
                         relating to the Group's Distribution Business); and

                    (B)  references to Northern  Electric plc to be deemed to be
                         references  to  Northern  Electric   Distribution  Ltd.
                         (being the Applicable Transferee).

5.   Please  provide  the  confirmations  referred  to in  paragraph  4 above by
     counter-signing  this letter (or a copy of the same) and  providing to each
     of the Issuer and us a counter-signed version of this letter.
