                    interests of any other  person,  the former shall prevail as
                    being paramount.

               (5)  In this Trust Deed  references to Coupons and  Couponholders
                    shall apply only if Definitive Bonds have been issued by the
                    Issuer in accordance with Clause 3.

out in the Conditions provided that (1) subject to Clause 2(D)(2), every payment
of any sum due in  respect of the Bonds made to the  Principal  Paying  Agent as
provided in the Paying  Agency  Agreement  shall,  to such extent,  satisfy such

(in the case of the Global  Bonds) to or to the order of the  bearer  thereof in
accordance  with the  provisions of the  Temporary  Global Bond or the Permanent
Global Bond, as the case may be, or (in the case of the Definitive Bonds) to the
relevant  Bondholders or (as the case may be) Couponholders under the Conditions
or (but only for the  purpose of AMBAC's  rights of  subrogation  under the Bond
Policy) to the extent that the relevant  payment is made by AMBAC under the Bond

Clause  8(I)),  except to the extent  that  there is  failure in the  subsequent
payment to the relevant  Bondholders or (as the case may be) Couponholders under
the  Conditions  or (but only for the purpose of AMBAC's  rights of  subrogation
under the Bond Policy) to the extent that the relevant  payment is made by AMBAC
under the Bond  Policy.  The Trustee  will hold the benefit of this  covenant on
trust for the Bondholders and Couponholders.

     (C) DISCHARGE: Subject to sub-Clause (D), any payment to be made in respect
of the Bonds, the Coupons,  this Trust Deed or the Bond Policy,  as the case may
be,  by the  Issuer,  the  Trustee  or  AMBAC  may be  made as  provided  in the
Conditions and the Paying Agency Agreement and any payment so made will (subject
to sub-Clause (D)) to such extent be a good discharge to the Issuer, the Trustee
or AMBAC,  as the case may be, subject to any rights of subrogation  which AMBAC
may acquire  against the Issuer by virtue of making any such  payment  under the
Conditions and the Bond Policy.

     (D) PAYMENT  AFTER A DEFAULT:  At any time after an Issuer Event of Default
or a  Potential  Issuer  Event of Default has  occurred  and is  continuing  the

     (1) by notice in  writing  to AMBAC,  the  Issuer  and the  Paying  Agents,
     require the Paying  Agents,  until notified by the Trustee to the contrary,
     so far as permitted by any applicable law:-

          (a) to act as Paying  Agents of the Trustee  under this Trust Deed and
          the  Bonds  on  the  terms  of  the  Paying  Agency   Agreement  (with
          consequential  amendments  as necessary  and except that the Trustee's
          liability  for  the   indemnification,   remuneration  and  all  other
          out-of-pocket  expenses  of the Paying  Agents  will be limited to the
          amounts for the time being held by the Trustee in respect of the Bonds
          on the terms of this Trust Deed) and thereafter to hold all Definitive
          Bonds and Coupons and all moneys,  documents  and records held by them
          in respect of the Bonds and Coupons to the order of the Trustee; or

          (b) to  deliver  all  Definitive  Bonds and  Coupons  and all  moneys,
          documents and records held by them in respect of the Bonds and Coupons
          (save for such  documents  and  records  which the  Paying  Agents are
          obliged not to release by virtue of any  applicable  law or regulation
          or by order of any court of competent  jurisdiction) to the Trustee or
          as the Trustee directs in such notice; and

     (2) by notice in writing to the  Issuer  require it to make all  subsequent
     payments  in  respect  of the Bonds and  Coupons  to or to the order of the
     Trustee and not to the Principal Paying Agent.

     (E)  FURTHER ISSUES:

     (1) The Issuer shall be at liberty from time to time (but subject always to
     the  provisions of this Trust Deed) without the consent of the  Bondholders
     or  Couponholders  to create and issue further  bonds or notes  (whether in
     bearer or  registered  form)  ranking pari passu in all respects (or in all
     respects save for the first payment of interest  thereon),  and so that the
     same shall be consolidated and form a single series,  with the Bonds and/or
     any further bonds or notes of any series, provided that:

          (a)  AMBAC has  consented  (in its  absolute  discretion)  to amend or
               substitute  the Bond  Policy so that the Bond  Policy also covers
               such further bonds or notes on the same terms mutatis mutandis as
               apply to the Bonds;

          (b)  the Trustee is  satisfied  that the rating  granted in respect of
               the  Bonds by S&P and  Moody's  will  not  thereby  be  adversely
               affected;  and

          (c)  the Issuer shall not create and issue such further bonds or notes
               while any default exists in relation to any payment by the Issuer
               of any amounts due under this Trust Deed.

                                       -7-


     (2) Any further bonds or notes which are to be created and issued  pursuant
     to the  provisions of paragraph (1) above shall be  constituted  by a trust
     deed supplemental to this Trust Deed. In such case the Issuer shall,  prior
     to the issue of such  further  bonds or notes,  execute  and deliver to the
     Trustee and AMBAC a trust deed supplemental to this Trust Deed (in relation
     to which all applicable stamp duties or other documentation fees, duties or
     taxes  have  been  paid  and,  if  applicable,   duly  stamped  or  denoted
     accordingly)  and  containing  a covenant by the Issuer in the form mutatis
     mutandis of Clause 2(B) in relation to the principal,  premium (if any) and
     interest  in  respect  of such  further  bonds  or  notes  and  such  other
     provisions  (corresponding to the provisions  contained in this Trust Deed)
     as the Trustee shall require.

     (3) A memorandum of every such supplemental Trust Deed shall be endorsed by
     the  Trustee  on this  Trust  Deed  and by the  Issuer  and  AMBAC on their
     duplicates of this Trust Deed.

     (4) Whenever it is proposed to create and issue any further  bonds or notes
     the  Issuer  shall  give to the  Trustee  and  AMBAC not less than 14 days'
     notice in writing of its  intention  so to do stating the amount of further
     bonds or notes proposed to be created and issued.

3.   FORM AND ISSUE OF THE BONDS

     (A) THE  GLOBAL  BONDS:  The Bonds will  initially  be  represented  by the
Temporary Global Bond without Coupons in the principal amount at the date hereof
of  (pound)200,000,000  which,  when duly  executed and  authenticated,  will be
deposited by the Issuer with Bankers Trust Company (the "Common  Depositary") as
common  depositary for Euroclear and Cedel Bank on the date hereof on terms that
the Common Depositary shall hold the Temporary Global Bond to or to the order of
the  Issuer  against  payment of the net  proceeds  of the issue of the Bonds in
accordance with the  Subscription  Agreement,  following which it shall hold the
Temporary Global Bond for the account of the Bondholders.  The Issuer shall also
deposit on the date  hereof the  Permanent  Global Bond  without  Coupons in the
principal  amount of up to  (pound)200,000,000  with the Common  Depositary  who
shall hold the Permanent  Global Bond pending  exchange of the Temporary  Global
Bond (in whole or in part) therefore in accordance with their respective  terms.
Following  exchange  of the  Temporary  Global  Bond in whole for the  Permanent
Global Bond in accordance with their  respective  terms the Bonds shall (subject
as provided in Clause 3(C) below)  thereafter  be  represented  by the Permanent
Global Bond.

The  procedures  as regards  the  issue,  exchange,  execution,  authentication,
delivery, surrender, cancellation, presentation and endorsement of the Temporary
Global  Bond and the  Permanent  Global  Bond (or part  thereof)  and any  other
matters to be carried out by the relevant  parties upon such  exchange (in whole
or in part) shall be made in  accordance  with this  Clause 3, their  respective
terms and the rules and  procedures  of  Euroclear  and Cedel  Bank for the time
being.

                                      -8-


     (B) SIGNATURE AND AUTHENTICATION: The Global Bonds and the Definitive Bonds
will be signed manually or in facsimile by a Director of the Issuer.  The Issuer
may use the facsimile signature of any person who at the date of this Trust Deed
is a Director of the Issuer even if at the time of issue of any Bonds  he/she no
longer holds such office.  The Issuer shall procure that, prior to the issue and
delivery of each Global  Bond,  each  Global  Bond will be  authenticated  by an
authorised  signatory on behalf of the Principal Paying Agent and no Global Bond
shall be valid for any purpose unless and until so  authenticated.  The Bonds so
executed  and,  if  applicable,  so  authenticated  shall be  binding  and valid
obligations  of the  Issuer.  Until it (or  part  thereof)  has  been  exchanged
pursuant to Clause 3(A) or (C) (but without prejudice to the escrow arrangements
referred to in Clause  3(A),  each Global  Bond (or part  thereof)  shall in all
respects be entitled to the same  benefits as a Definitive  Bond and each Global
Bond shall be subject to the  provisions  hereof except that the bearer  thereof
shall be the only person entitled to receive  payments of principal and interest
as set out therein.

     (C) EXCHANGE FOR DEFINITIVE  BONDS:  If while the Bonds are  represented by
one or more Global  Bonds (i) an AMBAC Event of Default  shall have  occurred or
(ii) either  Euroclear  or Cedel Bank is closed for  business  for a  continuous
period of 14 days (other than by reason of holiday,  statutory or  otherwise) or
announces an intention permanently to cease business or (iii) as a result of any
change in, or amendment to, the laws or  regulations of the United Kingdom or of
any political  sub-division  of, or any authority in, the United  Kingdom having
power to tax or any change in the application or official interpretation of such
laws or regulations  which becomes effective on or after 11th December 1997, the
Issuer, AMBAC or any Paying Agent is or will be required to make any withholding
or  deduction  from any  payment  in  respect  of the Bonds  which  would not be
required if the Bonds were in definitive form, then the Issuer shall (subject as
mentioned  below),  within 30 days of the  occurrence of such relevant event but
not prior to the expiry of a period of 40 days  commencing  on the date  hereof,
issue Definitive Bonds (with all unmatured Coupons attached) in exchange for the
whole (or the remaining  part(s)  outstanding) of the Permanent  Global Bond. If
any of the events  mentioned in (i),  (ii) or (iii) occurs  whilst the Bonds are
represented by the Temporary  Global Bond (or part thereof) the Temporary Global
Bond (or that part) shall  forthwith be exchanged for the Permanent  Global Bond
(or part thereof) in accordance with its terms and Clause 3(A) above so that the
Bonds are then  represented  solely by the Permanent Global Bond. All Definitive
Bonds shall be printed,  proofed,  executed and delivered as aforesaid but shall
be held by the  Principal  Paying Agent until a  Bondholder  requests the Issuer
through the  Principal  Paying Agent that his interest in the  Permanent  Global
Bond be exchanged for Definitive  Bonds whereupon such Definitive Bonds shall be
issued to such  Bondholder as aforesaid  without  charge.  The  procedures to be
carried  out by the  relevant  parties  upon  such  exchange  shall  be  made in
accordance  with the  provisions of the Permanent  Global Bond and the rules and
procedures of Euroclear and Cedel Bank for the time being.  The Permanent Global
Bond shall be endorsed by or on behalf of the Principal  Paying Agent in respect
of those Definitive Bonds which are so delivered.

     (D) THE DEFINITIVE  BONDS: The Definitive Bonds shall be serially  numbered
and  issued  in  bearer  form  in  the   denominations  of   (pound)10,000   and
(pound)100,000  each with all unmatured Coupons  attached.  The Definitive Bonds
and the Coupons will be security printed in accordance with all applicable stock
exchange  requirements in or  substantially  in the respective  forms set out in
Schedule 2 and the Definitive Bonds will be endorsed with the Conditions.

     (E) ENTITLEMENT TO TREAT HOLDER AS OWNER:  The holder of any Bond or Coupon
will (except as otherwise  required by law) be treated as its absolute owner for
all  purposes  (whether  or not it is overdue  and  regardless  of any notice of
ownership,  trust,  or any  interest  in it, any  writing on it, or its theft or
loss) and no person will be liable for so treating the holder.

                                      -9-

4.   STAMP DUTIES AND TAXES

     (A) STAMP  DUTIES:  The  Issuer  will pay any stamp,  issue,  registration,
documentary or other taxes and duties, including interest and penalties, payable
in Belgium,  Luxembourg and the United Kingdom in respect of the creation, issue
and offering of the Bonds and the Coupons and the  execution or delivery of this
Trust Deed. The Issuer will also indemnify the Trustee,  AMBAC,  the Bondholders
and  the  Couponholders  from  and  against  all  stamp,  issue,   registration,
documentary or other taxes paid by any of them in any jurisdiction in connection
with any action properly taken by or on behalf of the Trustee,  AMBAC or, as the
case may be, (where entitled under Condition 15 to do so) the Bondholders or the
Couponholders  to enforce the  obligations  of the Issuer under this Trust Deed,
the Bonds or the Coupons.

     (B) CHANGE OF TAXING JURISDICTION:  If the Issuer becomes subject generally
to the taxing  jurisdiction  of any  territory  or any  authority  of or in that
territory having power to tax other than or in addition to the United Kingdom or
any such  authority of or in the United Kingdom then the Issuer will (unless the
Trustee  otherwise  agrees)  in a trust  deed  supplemental  hereto  give to the
Trustee an undertaking in form and manner  satisfactory  to the Trustee in terms
corresponding to the terms of Condition 9 with the substitution  for, or (as the
case may be) the addition  to, the  references  in that  Condition to the United
Kingdom or any authority thereof or therein having power to tax of references to
that other or additional territory or authority to whose taxing jurisdiction the
Issuer has become so subject  and in such event this Trust  Deed,  the Bonds and
the Coupons will be read accordingly.  In addition, such supplemental trust deed
shall also modify  Condition 8(c) by the  substitution  for, or (as the case may
be) the addition to, the  references in that  Condition to the United Kingdom or
any authority in or of the United  Kingdom having power to tax, of references to
that other  territory or authority to whose taxing  jurisdiction  the Issuer has
become so subject and in such event this Trust  Deed,  the Bonds and the Coupons
will be read accordingly.

5.   THE TRUST DEED, THE BONDS AND THE BOND POLICY

     (A) BONDS  INCORPORATED BY REFERENCE:  The Issuer hereby covenants with the
Trustee and AMBAC that it will perform and comply with its obligations under the
Bonds which are  expressed to be binding on it.  Subject to Conditions 15 and 16
and Clause 19, the Trustee shall be entitled to enforce the  obligations  of the
Issuer under the Bonds and the Coupons in the manner therein  provided as if the
Bonds and the Coupons were  incorporated in this Trust Deed, which shall be read
and  construed  as one  document  with the Bonds.  The  provisions  contained in
Schedule 3 shall have effect in the same manner as if herein set forth.

     (B) BONDS AND BOND  POLICY  SUBJECT TO TRUST  DEED:  The Bonds and the Bond
Policy shall be subject to the provisions of this Trust Deed, all of which shall
be binding upon the Issuer, AMBAC, the Bondholders and the Couponholders and all
persons claiming through or under them respectively.

                                      -10-

     (C) EVIDENCE OF DEFAULT:  If the Trustee  makes any claim,  institutes  any
legal proceeding or lodges any proof in a winding up of the Issuer and/or AMBAC,
proof  that the  Issuer  or  AMBAC,  as the case may be,  has  failed to pay any
principal  or  interest  due and  payable in respect of any  particular  Bond or
Coupon shall  (unless the contrary is proved) be  sufficient  evidence  that the
Issuer or AMBAC,  as the case may be, has made the same  default as regards  all
other  Bonds or Coupons in respect of which a  corresponding  payment is due and
payable.

6.   APPLICATION OF MONEYS RECEIVED BY THE TRUSTEE

     (A)  DECLARATION  OF TRUST:  All moneys  received by the  Trustee  from the
Issuer in respect of the Bonds and all other  amounts  payable  under this Trust
Deed will be held by the Trustee upon trust to apply them (subject to sub-Clause
(B)):

     first, in payment of all costs, charges,  expenses and liabilities incurred
     by the Trustee (including  remuneration payable to the Trustee) in carrying
     out its functions under this Trust Deed;

     secondly,  in  payment  of any  interest  owing  in  respect  of the  Bonds
     (including any amounts owing to AMBAC pursuant to its rights of subrogation
     following  any payment of interest  by AMBAC  under the Bond  Policy)  pari
     passu and rateably;

     thirdly,  in payment of any principal and premium (if any) owing in respect
     of the Bonds (including any amounts of principal owing to AMBAC pursuant to
     its rights of subrogation following any payment of principal by AMBAC under
     the Bond Policy) pari passu and rateably; and

     fourthly, in payment of the balance (if any) to the Issuer for itself.

Without  prejudice to this sub-Clause (A), if the Trustee holds any moneys which
represent  principal,  premium or interest in respect of Bonds or Coupons  which
have become void under  Condition 10, the Trustee will hold such moneys upon the
above trusts  provided  that the Trustee shall be required to treat the payments
of interest  and/or  principal  and/or  premium as having been  satisfied and no
amounts as outstanding or owing in respect thereof. The Trustee shall as soon as
practicable  apply such moneys as aforesaid and promptly  thereafter return such
moneys (or the balance thereof, as the case may be) to the Issuer.

     (B)  ACCUMULATION:  If the amount of the moneys at any time  available  for
payment in respect of the Bonds under sub-Clause (A) is less than 10 per cent of
the  principal  amount of the Bonds then  outstanding,  the Trustee  may, at its
discretion,  invest such  moneys.  The Trustee may retain such  investments  and
accumulate the resulting  income until the  investments  and the  accumulations,
together  with any other  funds for the time  being  under  the  control  of the
Trustee and available  for such  payment,  amount to at least 10 per cent of the
principal  amount  of the Bonds  then  outstanding  and then  such  investments,
accumulations  and funds (after  deduction of, or provision  for, any applicable
taxes) will be applied as specified in sub-Clause (A).

     (C) INVESTMENT:  Any moneys held by the Trustee may be invested in the name
or under the control of the Trustee in any  investments  or other  assets in any
part of the world whether or not they produce income or are placed on deposit in
the name or under the  control of the  Trustee  at such bank or other  financial
institution and in such currency as the Trustee may, in its absolute discretion,
think fit.  The Trustee may at any time vary or transpose  any such  investments
for or into other such  investments  or convert any moneys so deposited into any
other currency,  and will not be responsible  for any loss  occasioned  thereby,
whether by depreciation in value, fluctuation in exchange rates or otherwise.

                                      -11-

7.   AMBAC AND THE BOND POLICY

     (A) NOTICES OF CLAIM: The Issuer shall procure that the Trustee is notified
by no later  than  close of  business  on the sixth  business  day  before  each
Scheduled  Payment Date if the amount available to the Issuer for payment of the
interest and (if  applicable)  principal which the Issuer is scheduled to pay on
such Scheduled Payment Date in respect of the Bonds and/or Coupons,  as the case
may be, is less than the Scheduled  Amount.  If such amount is insufficient  for
payment of the Scheduled Amount,  the Trustee shall deliver a Notice of Claim to
AMBAC with a copy to the Issuer and the Principal  Paying Agent  requiring AMBAC
to pay the shortfall in accordance with the terms of the Bond Policy.

     (B)  PAYMENTS  UNDER BOND POLICY AT AMBAC'S  OPTION:  Any election by AMBAC
under the Bond Policy to pay any amount of principal in respect of the Bonds and
any  accrued  interest  thereon  which has become  immediately  due and  payable
(whether by virtue of  acceleration,  prepayment or otherwise) other than on the
relevant  Scheduled  Payment  Date  shall be made by  notice in  writing  to the
Trustee,  with a copy to the Issuer and the Principal  Paying Agent,  specifying
the date on which such amount will be paid by AMBAC.

     (C) PAYMENTS UNDER BOND POLICY TO GO TO PRINCIPAL PAYING AGENT: The Trustee
shall  direct  AMBAC to pay all  sums  payable  under  the  Bond  Policy  to the
Principal  Paying Agent;  provided  that at any time after the  occurrence of an
Issuer Event of Default,  a Potential  Issuer Event of Default or an AMBAC Event
of  Default  or in the  event  that  the  Trustee  considers  that it  would  be
inappropriate  for  such  sums to be paid to the  Principal  Paying  Agent,  the
Trustee may require AMBAC to make payments to the Trustee or as it may otherwise
direct.

     (D) NOTICE OF AMBAC'S  TRANSFER  INSTRUCTIONS:  At least one  business  day
before  each date on which  AMBAC is  obliged  to make a payment  under the Bond
Policy,  it shall notify the Trustee,  the Issuer and the Principal Paying Agent
of its irrevocable  instructions to the bank effecting  payment on its behalf to
transfer such amount in accordance with the relevant Notice of Claim.

                                      -12-


     (E) THE ISSUER NOT DISCHARGED:  The Issuer shall not be discharged from its
obligations  under the Bonds and this Trust Deed by any  payment  under the Bond
Policy:  provided that this sub-clause shall operate only for the purpose of the
rights of subrogation of AMBAC contemplated by sub-clause (G).

     (F) RETURN OF BOND POLICY: The Trustee will return the Bond Policy to AMBAC
for cancellation upon:

     (a) the redemption in full of the Bonds by the Issuer,  the payment in full
     of accrued  interest  thereon and the expiry of any  applicable  preference
     period  during  which the  amount of any  payments  in respect of the Bonds
     which  are  subsequently  avoided  in  whole  or in part as a  preferential
     transaction  under applicable law may be required to be paid by AMBAC under
     the Bond Policy; or

                                      -12-


     (b) the  payment in full of all  amounts  which are or may become due under
     the Bond Policy.

     (G) SUBROGATION:  Without prejudice to its other rights and remedies, AMBAC
shall be  subrogated  to all and any rights of the bearers of the Global  Bonds,
the  Bondholders,  the  Couponholders  and the Trustee against the Issuer to the
extent of amounts  due and  payable in respect of the Bonds which have been paid
by AMBAC under the Bond Policy.

     (H) CONFLICT:  To the extent that the provisions of this Trust Deed and the
Bond Policy conflict, the provisions of the Bond Policy shall prevail.

permitted  by  applicable  law,  allow and  procure  that each of its  Principal
Subsidiaries  will allow the  Trustee,  AMBAC (so long as it is the  Controlling

this  Trust  Deed  or,  if  later,  the  Certification  Date  of the  last  such
certificate (if any) and is continuing or, if such an event had occurred, giving
details of it, provided however that the Issuer shall not be required to provide
any such certificate more than twice in any calendar year unless the Trustee and

Issuer  Event of Default  has  occurred  (in which case the Issuer  shall not be
required to provide a certificate more than once in any two week period);

approved  by the  Trustee  (such  approval  not to be  unreasonably  withheld or

effect;

     (P) NEGATIVE PLEDGE: give notice to the Trustee and to AMBAC (so long as no
AMBAC Event of Default has occurred and is  continuing)  as soon as  practicable

permit  to arise or  subsist  any  Security  Interest  to  secure  any  Relevant
Indebtedness  or any  guarantee  of or  indemnity  in  respect  of any  Relevant
Indebtedness or become aware of the existence of any such Security Interest,  in
each case where the  creation or  existence  of which would  oblige the Security
Interest to be extended to the Bonds pursuant to Condition 5 or Condition 11;

     (Q) OBLIGATIONS UNDER PAYING AGENCY AGREEMENT:  comply with and perform all
its obligations under the Paying Agency Agreement and use all its best endeavors
to procure that the Paying Agents  comply with and perform all their  respective
obligations  hereunder  and any notice  given by the Trustee  pursuant to Clause
2(D)( 1) and  notify  the  Trustee  and  AMBAC (if then the  Controlling  Party)
forthwith  on being  notified  in writing by the  relevant  Paying  Agent of any

               the Northern Group.

               A  report  by the  Auditors  as to  the  amount  of the  Northern

                    Subsidiary Undertakings.

                    by Section 258 of the  Companies Act 1985 (but shall exclude
                    any  undertakings  (as  defined in the  Companies  Act 1985)
                    whose accounts are not included in the then latest published
                    audited consolidated  accounts of Northern Electric plc, nor

                    subsidiary  undertaking  of a member of the  Northern  Group
                    since the date as at which any such  audited  accounts  were
                    prepared)  would  its  accounts  have  been so  included  or
                    consolidated if it had become so on or before that date.

               (4)  Any  reference  to  an  obligation  being  guaranteed  shall
                    include a reference to any indemnity  being given in respect
                    of the obligation.

11.  REMUNERATION AND INDEMNIFICATION OF THE TRUSTEE

     (A) NORMAL REMUNERATION: So long as any Bond is outstanding the Issuer will
pay to the Trustee by way of  remuneration  for its services as Trustee such sum
as may from time to time be agreed between them. Such  remuneration  will accrue
from day to day from the date of this  Trust  Deed and shall be  payable on such
dates as may from time to time be agreed  between  the Issuer  and the  Trustee.
However,  if any payment to a Bondholder  or  Couponholder  of the moneys due in
respect  of any Bond or  Coupon  is  improperly  withheld  or  refused  upon due
presentation of such Bond or Coupon, such remuneration will again accrue as from
the date of such  presentation  until payment to such Bondholder or Couponholder
is duly made.

     (B) EXTRA REMUNERATION: At any time after the occurrence of an Issuer Event
of Default or an AMBAC Event of Default or if the Trustee  finds it expedient or
necessary or is  requested  by the Issuer to undertake  duties which the Trustee
and the Issuer agree to be of an  exceptional  nature or  otherwise  outside the
scope of the normal duties of the Trustee under this Trust Deed, the Issuer will
pay such  additional  remuneration  as may be agreed  between  them or,  failing
agreement  as to any of the  matters  in this  sub-Clause  (or as to  such  sums
referred to in sub-Clause  (A)), as determined by a merchant or investment  bank
(acting as an expert)  selected by the  Trustee  and  approved by the Issuer or,
failing such approval,  nominated by the President for the time being of The Law
Society of England and Wales,  the expenses  involved in such nomination and the
fee  of  such  merchant  or  investment  bank  being  paid  by the  Issuer.  The
determination of such merchant or investment bank will be conclusive and binding
on the Issuer, the Trustee,  the Bondholders and the Couponholders,  save in the
case of manifest error.

     Nothing  in this  Trust  Deed  shall in any case in which the  Trustee  has
failed  to show the  degree  of care and  diligence  required  of it as  trustee
relieve or  indemnify  it from or against any  liability  which by virtue of any
rule of law would otherwise attach to it in respect of any negligence,  default,
breach of duty or breach of trust of which it may be guilty.

14.  WAIVER

     (A) WAIVER: Subject to Condition 16 and Clause 19, the Trustee may, subject
to the prior written consent of AMBAC (if AMBAC is then the Controlling  Party),
without the consent of the Bondholders or Couponholders and without prejudice to
its  rights in respect of any  subsequent  breach,  from time to time and at any
time, if in its opinion the interests of the Bondholders  will not be materially
prejudiced  thereby,  waive or authorize,  on such terms and conditions as seems
expedient  to it,  any  breach or  proposed  breach by the  Issuer of any of the
provisions  of this  Trust  Deed or the  Bonds  or  determine  that  any  event,
condition  or act  which  would  otherwise  be an  Issuer  Event of  Default  or
Potential  Issuer  Event of Default  will not be treated as such  provided  that
where the Trustee is the Controlling  Party, it will not do so in  contravention
of any  express  direction  given by an  Extraordinary  Resolution  or a written
request  made  pursuant to  Condition  12 but no such  direction or request will
affect any previous  waiver,  authorisation or  determination.  Any such waiver,
authorisation  or  determination  will be  binding  on the  Bondholders  and the
Couponholders  and,  if  the  Trustee  so  requires,  will  be  notified  to the
Bondholders as soon as practicable.

     (B)  PROCEEDINGS:  At any time after amounts in respect of principal of and
interest on the Bonds shall have become due and payable, the Trustee may, at its
discretion, and without further notice but subject as mentioned below, take such
proceedings against:

          (i)  the Issuer as it may think fit to enforce the  provisions of this
               Trust Deed; and/or

          (ii) AMBAC as it may think fit to enforce the  provisions  of the Bond
               Policy.

     If the Trustee is not the  Controlling  Party it shall not be  permitted to
take any such  proceedings  against the Issuer  and/or  AMBAC unless it has been
directed  by the  Controlling  Party  to do so and  shall  only be bound to take
proceedings  against the Issuer at the direction of the Controlling  Party if it
has been  indemnified to its  satisfaction by the Controlling  Party (or, if the
Trustee  is the  Controlling  Party,  unless  it  has  been  indemnified  to its
satisfaction by the Bondholders).

     (C) NO ACTION BY BONDHOLDERS OR COUPONHOLDERS:  Subject as provided in this
Trust Deed (including the  Conditions)  only the Trustee may pursue the remedies
available  under  general  law or under this Trust Deed to enforce the rights of
the Bondholders or Couponholders  and no such holder will be entitled to proceed
against the Issuer or AMBAC  unless the Trustee,  having  become bound to act in
accordance with the terms of this Trust Deed, fails to do so and such failure is
continuing. If, in connection with any insolvency,  bankruptcy,  administration,
dissolution,  liquidation  or  analogous  procedure  relating to the  Issuer,  a
payment  on  the  Bonds  by the  Issuer  is  claimed  to be or is  avoided  as a
preferential  transfer,  AMBAC may (provided that AMBAC is then the  Controlling
Party)  direct all matters  relating to such claim or avoidance on behalf of the
Trustee, the Bondholders and the Couponholders.

                                      -26-


15.  TRUSTEE NOT PRECLUDED FROM ENTERING INTO CONTRACTS

precluded  from becoming the owner of, or acquiring any interest in,  holding or
disposing of any Bond or Coupon or any shares or securities of the Issuer or any
of its  subsidiary,  holding or associated  companies with the same rights as it
would have had if the Trustee  were not Trustee or from  entering  into or being
interested in any contracts or  transactions  with the Issuer or its subsidiary,
holding or  associated  companies or from acting on, or as  depositary  or agent
for,  any  committee or body of holders of any  securities  of the Issuer or its
subsidiary,  holding or  associated  companies and will not be liable to account
for any profit.

16.  MODIFICATION AND SUBSTITUTION

Subject to Condition 16 and Clause 19:

     (A)  MODIFICATION:  Subject to the prior written consent of AMBAC (if AMBAC
is then the  Controlling  Party) the  Trustee  may,  without  the consent of the
Bondholders or  Couponholders,  agree (i) to any modification to this Trust Deed
or the  Conditions  or the Bond Policy which is of a formal,  minor or technical
nature or is made to correct a  manifest  error or (ii) to any  modification  to
this Trust Deed,  the  Conditions or the Bond Policy which is in its opinion not
materially   prejudicial  to  the  interests  of  the   Bondholders.   Any  such
modification  shall be binding on the  Bondholders  and the  Couponholders  and,
unless the Trustee agrees otherwise, the Issuer shall cause such modification to
be notified to the  Bondholders as soon as practicable  thereafter in accordance
with the Conditions. Notwithstanding the provisions of the foregoing, the Issuer
and AMBAC may, without the consent of the Bondholders or Couponholders, agree to
any modification to Condition 11 and to Clause 10 of this Trust Deed.

     (B) SUBSTITUTION:

     Couponholders,  agree with the  Issuer,  with the  consent  of AMBAC  (such
     consent not to be unreasonably withheld or delayed), to the substitution of
     any wholly-owned  Subsidiary of the Issuer (the  "SUBSTITUTED  OBLIGOR") in
     place of the Issuer (or of any previous  substitute  under this sub-Clause)
     as the  principal  debtor under this Trust Deed,  the Bonds and the Coupons
     provided  that,  in  the  opinion  of the  Trustee,  the  interests  of the
     Bondholders  will not be  materially  prejudiced  thereby and also provided
     that:

                                      -27-


          (a) a trust deed is  executed  or some other  form of  undertaking  is
          given by the  Substituted  Obligor to the Trustee,  in form and manner
          satisfactory to the Trustee, agreeing to be bound by the terms of this
          Trust  Deed,  the  Bonds  and  the  Coupons  with  any   consequential
          amendments  which the Trustee may deem  appropriate as fully as if the
          Substituted Obligor had been named in this Trust Deed and on the Bonds
          and Coupons as the principal debtor in place of the Issuer;

          (b) where the Substituted  Obligor is subject  generally to the taxing
          jurisdiction of any territory or any authority of or in that territory
          having  power  to tax (the  "SUBSTITUTED  TERRITORY")  other  than the
          territory  to the  taxing  jurisdiction  of  which  (or  to  any  such
          authority  of or in  which)  the  Issuer  is  subject  generally  (the
          "ISSUER'S  TERRITORY"),  the  Substituted  Obligor  will  (unless  the
          Trustee  otherwise  agrees) give to the Trustee an undertaking in form
          and manner  satisfactory to the Trustee in terms  corresponding to the
          terms of Condition 9 with the  substitution for the references in that
          Condition to the Issuer's  Territory of references to the  Substituted
          Territory and  Condition  8(c) shall be modified  accordingly;  and in
          such  event the Trust  Deed,  the Bonds and the  Coupons  will be read
          accordingly;

          (c) if any two of the  Directors of the  Substituted  Obligor  certify
          that it will be  solvent  immediately  after  such  substitution,  the
          Trustee need not have regard to the  financial  condition,  profits or
          prospects of the Substituted Obligor or compare them with those of the
          Issuer;

          (d) the  Issuer and the  Substituted  Obligor  comply  with such other
          requirements  as  the  Trustee  may  direct  in the  interests  of the
          Bondholders; and

          (e)  (unless the  Issuer's  successor  in business is the  Substituted
          Obligor) the obligations of the  Substituted  Obligor under this Trust
          Deed, the Bonds and the Coupons are  unconditionally  and  irrevocably
          guaranteed  by the  Issuer  in form  and  manner  satisfactory  to the
          Trustee.

     (2)  RELEASE OF  SUBSTITUTED  ISSUER:  Any such  agreement  by the  Trustee
     pursuant to sub-Clause  (B) will,  if so expressed,  operate to release the
     Issuer (or any such previous substitute) from any or all of its obligations
     under this Trust Deed,  the Bonds and the  Coupons.  Not later than 14 days
     after the execution of any such  documents and after  compliance  with such
     requirements, notice of the substitution will be given to the Bondholders.

     (3)  COMPLETION OF  SUBSTITUTION:  Upon the execution of such documents and
     compliance with such requirements,  the Substituted  Obligor will be deemed
     to be named in this  Trust  Deed and the Bond  Policy  and on the Bonds and
     Coupons as the principal debtor in place of the Issuer (or of any; previous
     substitute under sub-Clause (B)) and this Trust Deed, the Bond Policy,  the
     Bonds and the Coupons will be deemed to be modified in such manner as shall
     be necessary to give effect to the substitution.

17.  APPOINTMENT, RETIREMENT AND REMOVAL OF THE TRUSTEE

     (A) APPOINTMENT:  The Issuer will have the power of appointing new trustees
but  no  person  will  be  so  appointed  unless   previously   approved  by  an
Extraordinary  Resolution  of  Bondholders  and approved in writing by AMBAC (if
then the Controlling  Party). A trust corporation will at all times be a Trustee
and may be the sole Trustee.  Any  appointment of a new Trustee will be notified
by the Issuer to the Bondholders as soon as practicable.

                                      -28-


     (B)  RETIREMENT  AND  REMOVAL:  The Trustee may not resign its  appointment
unless a successor,  willing to act in such capacity,  has been appointed by the
Issuer with the prior consent of AMBAC (if AMBAC is then the Controlling  Party)
and the Bondholders by Extraordinary Resolution, provided that the Trustee shall
not be prevented  from  resigning  its  appointment  if,  having given notice in
writing to the Issuer and AMBAC (if AMBAC is then the Controlling  Party) of its
intention to resign its  appointment,  a successor is not  appointed  within the
period of three  months from the date of such  notice.  The  Bondholders  may by
Extraordinary  Resolution  remove any Trustee  provided  that the  retirement or
removal of any sole trustee or sole trust  corporation will not become effective
until a trust corporation is appointed as successor  Trustee.  If a sole trustee
or sole  trust  corporation  gives  notice  of  retirement  or an  Extraordinary
Resolution is passed for its removal under this Clause,  the Issuer will use its
best  endeavors  to procure  that  another  trust  corporation  be  appointed as
Trustee.

     (C)  CO-TRUSTEES:  The Trustee may,  despite  sub-Clause  (A), by notice in
writing to the Issuer  appoint  anyone to act as an additional  Trustee  jointly
with the Trustee:

     (a) if the Trustee considers such appointment to be in the interests of the
     Bondholders and/or the Couponholders;

     (b for the purpose of conforming with any legal requirement, restriction or
     condition  in  any  jurisdiction  in  which  any  particular  act  is to be
     performed; or

     (c) for the  purpose of  obtaining a judgment  in any  jurisdiction  or the
     enforcement  in any  jurisdiction  against  the Issuer of either a judgment
     already obtained or any of the provisions of this Trust Deed,

Subject  to the  provisions  of this Trust  Deed the  Trustee  may confer on any
person so appointed  such  functions as it thinks fit, The Trustee may by notice
in writing to the Issuer and such person remove any person so appointed.  At the
request  of the  Trustee,  the  Issuer  will  forthwith  do all things as may be
required to perfect such appointment or removal and it irrevocably  appoints the
Trustee to be its attorney in its name and on its behalf to do so.

     (D)  COMPETENCE  OR A  MAJORITY  OF  TRUSTEES:  If there  are more than two
Trustees the majority of such Trustees will (provided  such majority  includes a
trust  corporation)  be  competent  to  carry  out  all or any of the  Trustee's
functions.

18.  COUPONS

     (A) NOTICES: Neither the Trustee nor the Issuer need give any notice to the
Couponholders  and the  Couponholders  will be  deemed  to  have  notice  of the
contents  of any  notice  given  to  the  Bondholders  in  accordance  with  the
Conditions.
                                      -29-


     (B) BONDHOLDERS  ASSUMED TO HOLD COUPONS:  Even if it has express notice to
the contrary,  whenever the Trustee is required to exercise any of its functions
by reference to the interests of the  Bondholders,  the Trustee will assume that
each Bondholder is the holder of all Coupons  appertaining to each Bond of which
he is the bearer.  The  holders of Coupons  shall be bound by and subject to the
terms  of this  Trust  Deed to the  same  extent  as if they  were  Bondholders;
provided  that no holder of a Coupon shall have any right of action by virtue of
this Trust Deed or its holding of such Coupon.

19.  CONTROLLING PARTY

     Subject  to (i)  AMBAC  being at that time the  Controlling  Party and (ii)
AMBAC giving notice to the Trustee that it intends to exercise the Trust Rights,
AMBAC shall have exclusive control to exercise the Trust Rights or to direct the
exercise of the Trust Rights (as applicable)  without regard to the interests of
any other person, and will not be a fiduciary or owe any fiduciary duties to any
person  under the Trust Deed and will be  exclusively  authorised  to direct and
refrain from directing, the Trustee under this Trust Deed in the exercise of the
Trust Rights without regard to the interests of any other person,  provided that
such  power  shall not  extend to permit  AMBAC (i) to  exercise  or direct  the
exercise of the Excluded Rights, which shall, so long as any of the Bonds remain
outstanding, be exercisable by the Trustee in its sole discretion without regard
to the  provisions  of  Condition  16 or this  Clause 19, or (ii) to require any
modification as is mentioned in the proviso to paragraph 19 of Schedule 3.

20.  CURRENCY INDEMNITY

     (A)  CURRENCY OF ACCOUNT AND PAYMENT:  Pounds  sterling  (the  "CONTRACTUAL
CURRENCY")  is the sole  currency of account and payment for all sums payable by
the  Issuer  under or in  connection  with this  Trust  Deed,  the Bonds and the
Coupons, including damages.

     (B) EXTENT OF  DISCHARGE:  Any amount  received or  recovered in a currency
other  than  the  Contractual  Currency  (whether  as a  result  of,  or of  the
enforcement  of, a  judgment  or order  of a court of any  jurisdiction,  in the
winding-up  or  dissolution  of the Issuer or  otherwise),  by the  Trustee  any
Bondholder or  Couponholder in respect of any sum expressed to be due to it from
the Issuer will only  constitute  a discharge to the Issuer to the extent of the
Contractual  Currency  amount which the  recipient is able to purchase  with the
amount so  received  or  recovered  in that other  currency  on the date of that
receipt or recovery (or, if it is not  practicable to make that purchase on that
date, on the first date on which it is practicable to do so).

     (C)  INDEMNITIES:  If that  Contractual  Currency  amount  is less than the
Contractual  Currency  amount  expressed to be due to the  recipient  under this
Trust Deed,  the Bonds or the Coupons,  the Issuer will indemnify it against any
loss  sustained by it as a result.  In any event,  the Issuer will indemnify the
recipient against the cost of making any such purchases.

     (D)  INDEMNITIES  SEPARATE:  These  indemnities  constitute  a separate and
independent  obligation from the other obligations in this Trust Deed, will give
rise to a separate and independent cause of action,  will apply  irrespective of
any indulgence  granted by the Trustee and/or any Bondholder or Couponholder and
will  continue in full force and effect  despite any judgment,  order,  claim or
proof for a  liquidated  amount in respect of any sum due under this Trust Deed,
the Bonds and/or the Coupons or any  judgment or order.  No proof of evidence of
any actual loss may be required.

                              TEMPORARY GLOBAL BOND

                                  representing

               (pound)200,000,000 7.25% Guaranteed Bonds due 2022
       unconditionally and irrevocably guaranteed as to scheduled payments
  of principal and interest pursuant to a financial guarantee insurance policy
                      issued by AMBAC Insurance UK Limited

This Bond is a Temporary  Global Bond without  interest  coupons in respect of a
duly authorised issue of Bonds of CE Electric UK Funding Company (the "Issuer"),
designated  as  specified  in the title  hereof  (the  "Bonds"),  limited to the
aggregate principal amount of

            Two Hundred Million Pounds Sterling ((pound)200,000,000)

            or, if less, that amount as shall be shown by the latest
                entry duly made in each of the Schedules hereto,

and  constituted  by a Trust Deed dated 15th  December  1997 (the "TRUST  DEED")
between the Issuer,  AMBAC Insurance UK Limited  ("AMBAC") and The Law Debenture
Trust  Corporation  plc, as trustee (the  "TRUSTEE").  References  herein to the
Conditions (or to any particular  numbered  Condition) shall be to the Terms and
Conditions of the Bonds (or that  particular  one of them) set out in Schedule 2
to the Trust Deed.

                                      -33-


If the Issuer becomes obliged to issue  definitive Bonds pursuant to Clause 3(C)
of the Trust Deed, this Temporary Global Bond will be exchangeable in whole upon
the request of the bearer hereof for interests in a Permanent  Global Bond in or
substantially  in the form set out in Part B of  Schedule 1 to the Trust Deed on
and subject to the terms and conditions set out below and in the Trust Deed.

The Issuer hereby promises to pay to the bearer hereof the principal sum of this
Temporary Global Bond being at the date hereof:

            TWO HUNDRED MILLION POUNDS STERLING ((POUND)200,000,000)

or such lesser amount as may from time to time be  represented by this Temporary
Global Bond (or such part thereof or such greater amount as may become repayable
pursuant to the  Conditions)  on such date(s) as the said principal sum (or part
thereof)  and  premium,  if any, may become  repayable  in  accordance  with the
Conditions  and the Trust Deed and to pay  interest  in arrear on each  Interest
Payment Date (as defined in Condition 6) on the principal amount  outstanding of
this  Temporary  Global Bond at the rate specified in Condition 6 all subject to
and  in  accordance  with  the  certification  requirements  described  in  this
Temporary Global Bond, the Conditions and the Trust Deed, which shall be binding
upon the bearer hereof (as if references in the  Conditions to the Bonds and the
Bondholders  were references to this Temporary Global Bond and the bearer hereof
respectively  and as if the  same  had  been  set out  herein  in  full  mutatis
mutandis), except as otherwise provided herein.

Payments of interest (if any) on this Temporary  Global Bond or any part of this
Temporary  Global  Bond  due to be made  prior  to the  date or  dates  on which
interests  in this  Temporary  Global  Bond (or that  part)  are  exchanged  for
interests  in a Permanent  Global Bond (as  provided  below) which date or dates
shall be no earlier  than the  Exchange  Date (as  defined  below)  may,  at the
direction of the bearer hereof, be made on each due date for any such payment to
Morgan Guaranty Trust Company of New York,  Brussels office,  as operator of the
Euroclear system ("EUROCLEAR") and/or Cedel Bank, societe anonyme ("CEDEL BANK")
for credit to the accounts of the persons  appearing in the records of Euroclear
and/or Cedel Bank as being entitled thereto provided that any such payment shall
only be made in respect of the Bonds in  relation to which there shall have been
presented to Bankers Trust Company in its capacity as principal  paying agent in
respect of the Bonds (the "PRINCIPAL PAYING AGENT") at its head office in London
for the time being,  a certificate  in the form set out in Exhibit A hereto from
Euroclear  and/or  Cedel  Bank,  as the case may be, to the  effect  that it has
received from or in respect of such persons,  a certificate from such persons in
the  form of  Exhibit  B  hereto.  Otherwise  no  interest  will be paid on this
Temporary  Global  Bond or any part of this  Temporary  Global  Bond  until this
Temporary  Global Bond (or that part) is so  exchanged  for a  Permanent  Global
Bond.

Upon any payment of principal,  premium (if any) and/or interest on the Bonds as
referred to above  details of such payment  shall be endorsed by or on behalf of
the  Issuer  on the  First  Schedule  hereto  and,  in the case of  payments  of
principal,  the  principal  amount  outstanding  hereof shall be reduced for all
purposes by the amount so paid and endorsed. All payments of any amounts payable
and paid to the bearer of this Temporary  Global Bond shall be valid and, to the
extent of the sums so paid, effectual to satisfy and discharge the liability for
the moneys  payable  hereon,  on the  Permanent  Global Bond and on the relative
Definitive Bonds and Coupons.

                                      -34-


On or after the date  which is not  earlier  than 40 days  after the date of the
issue of the Bonds  represented  by this  Temporary  Global Bond (the  "EXCHANGE
DATE"), this Temporary Global Bond may be exchanged in whole or in part (free of
charge to the holder) for a Permanent  Global Bond in the form set out in Part B
of Schedule 1 to the Trust Deed upon  presentation of this Temporary Global Bond
by the bearer hereof to the Principal  Paying Agent at its head office in London
for the time being (or such other place  outside  the United  States of America,
its territories,  its possessions and other areas subject to its jurisdiction as
the Trustee may agree). The Permanent Global Bond shall be delivered in exchange
for only that part of this Temporary Global Bond in respect of which there shall
have been  presented to the Principal  Paying Agent by Euroclear or Cedel Bank a
certificate,  in the form set out in Exhibit A hereto, to the effect that it has
received  from or in respect of a person or persons  entitled to a Bond or Bonds
comprising  or comprised  in such part (as shown by its  records) a  certificate
from such person or persons in or substantially in the form set out in Exhibit B
hereto.  On an exchange of part only of this Temporary  Global Bond,  details of
such  exchange  shall be  entered  by or on behalf of the  Issuer in the  Second
Schedule hereto and the relevant space in the Second  Schedule hereto  recording
such  exchange  shall be  signed by or on behalf  of the  Issuer  whereupon  the
principal  amount of the Bonds to which this Temporary Global Bond relates shall
be reduced for all purposes by the  principal  amount so exchanged  and endorsed
and the Second Schedule to the Permanent Global Bond shall be marked accordingly
by or on behalf of the Issuer  whereupon the  principal  amount of the Permanent
Global Bond shall be increased by such amount.  If,  following the date of issue
hereof,  any Bonds represented by this Temporary Global Bond are purchased by or
on  behalf  of  the  Issuer  or  any  of its  Subsidiaries  (as  defined  in the
Conditions) and surrendered for  cancellation,  the Principal Paying Agent shall
endorse  the Second  Schedule  hereto to reflect the  decrease in the  aggregate
principal  amount  of  this  Temporary  Global  Bond  due to such  purchase  and
cancellation,  whereupon the principal  amount hereof shall be decreased for all
purposes by the principal amount of the Bonds so purchased and cancelled.  On an
exchange of the whole of this Temporary  Global Bond, this Temporary Global Bond
shall be  surrendered  to or to the order of the  Principal  Paying  Agent.  If,
following  the issue of a Permanent  Global Bond in exchange for this  Temporary
Global Bond, further Bonds are to be exchanged pursuant to this paragraph,  such
exchange may be effected,  without the issue of a new Permanent  Global Bond, by
the Principal Paying Agent endorsing the Second Schedule of the Permanent Global
Bond previously issued to reflect an increase in the aggregate  principal amount
of such  Permanent  Global Bond by an amount  equal to the  aggregate  principal
amount of the Permanent  Global Bond which would  otherwise  have been issued on
such exchange.

Any certificate  referred to in this Temporary Global Bond which is delivered by
Euroclear or Cedel Bank may be relied upon by the Issuer, the Trustee, AMBAC and
the  Principal  Paying  Agent as  conclusive  evidence  that  the  corresponding
certification or certifications  have been delivered to Euroclear or Cedel Bank,
as the case may be, as contemplated by the terms of this Temporary Global Bond.

                                      -35-


So long as all the Bonds are  represented by this Temporary  Global Bond and the
same  is/are  held  on  behalf  of  Euroclear  and/or  Cedel  Bank,  notices  to
Bondholders   may  be  given  by  delivery  to  Euroclear  and  Cedel  Bank  for
communication  by them to the persons for the time being shown in the records of
Euroclear  and Cedel  Bank  (other  than  Cedel  Bank if Cedel  Bank shall be an
accountholder  of Euroclear  and other than  Euroclear if Euroclear  shall be an
accountholder of Cedel Bank) as being holders of the Bonds ("accountholders") in
which regard any certificate or other document issued by Cedel Bank or Euroclear
as to the principal  amount of Bonds standing to the account of any person shall
be  conclusive  and binding  for all  purposes  (other than for the  purposes of
payments in respect thereof,  the right to which shall be vested, as against the
Issuer and the Trustee,  solely in the bearer of this  Temporary  Global Bond or
the  Permanent  Global Bond in accordance  with and subject to their  respective
terms and the terms of the Trust  Deed),  in  substitution  for  publication  as
required by the  conditions;  provided  that, so long as the Bonds are listed on
the Luxembourg Stock Exchange and the rules of that exchange so require, notices
shall also be published in a leading  newspaper  having  general  circulation in
Luxembourg (which is expected to be the Luxemburger Wort).

In considering the interests of Bondholders  while this Temporary Global Bond is
held on behalf of  Euroclear  or Cedel Bank,  the Trustee may have regard to any
information  provided to it by such clearing  system as to the identity  (either
individually  or by category) of its  accountholders  with  entitlement  to this
Temporary Global Bond and may consider such interests as if such  accountholders
were the holders of the Bonds represented by this Temporary Global Bond.

For so long as all the Bonds are  represented by this Temporary  Global Bond, no
drawing of Bonds will be  required  under  Condition  8(b) in the event that the
Issuer exercises its option in Condition 8(b) while the Bonds are represented by
this  Temporary  Global  Bond in  respect of less than the  aggregate  principal
amount of Bonds  outstanding at such time. Bonds will be selected for redemption
in accordance  with the rules and procedures  from time to time of Euroclear and
Cedel Bank.

The  Bondholders'  option in Condition 14 may be exercised by the holder of this
Temporary  Global  Bond  giving  notice  to the  Principal  Paying  Agent of the
principal  amount of Bonds in  respect  of which the  option  is  exercised  and
presenting  this Temporary  Global Bond for  endorsement of exercise  within the
time limits specified in Condition 14.

This  Temporary  Global Bond is subject to the Conditions and the Trust Deed and
until the whole of this  Temporary  Global  Bond shall have been  exchanged  for
equivalent  interests in the Permanent  Global Bond its holder shall be entitled
to the same benefits as if he were the holder of the  Permanent  Global Bond (or
the relevant part of it as the case may be) except that, save as provided above,
no person  shall be entitled to receive  any  payment on this  Temporary  Global
Bond.

This Temporary Global Bond shall become void unless presented for payment within
ten years (in  respect of payment of  principal  and  premium  (if any)) or five
years (in respect of payment of interest),  respectively, from the Relevant Date
(as  defined in  Condition  9) for  payment in respect  thereof,  subject to the
provisions  of  Condition 7. All  references  in this  Temporary  Global Bond to
Euroclear or Cedel Bank shall be deemed to include such  substitute or successor
clearing system as may be approved by the Trustee from time to time.

                                      -36-


This  Temporary  Global Bond shall not become  valid for any purpose  unless and
until the Certificate of Authentication  hereon has been signed by an authorised
signatory of the Principal Paying Agent.

This Temporary  Global Bond is governed by, and shall be construed in accordance
with, the laws of England.

IN WITNESS whereof the Issuer has caused this Temporary Global Bond to be signed
manually or in facsimile by a Director of the Issuer on its behalf.

  OF PRINCIPAL AND INTEREST PURSUANT TO A FINANCIAL GUARANTEE INSURANCE POLICY
                      ISSUED BY AMBAC INSURANCE UK LIMITED

This Bond is a Permanent  Global Bond without  interest  coupons in respect of a
duly authorized issue of Bonds of CE Electric UK Funding Company (the "Issuer"),
designated  as  specified  in the title  hereof  (the  "Bonds"),  limited to the
aggregate principal amount of up to

            TWO HUNDRED MILLION POUNDS STERLING ((POUND)200,000,000)

and  constituted  by a Trust Deed dated 15th  December  1997 (the "Trust  Deed")
between the Issuer,  AMBAC  Insurance  UK Limited  and The Law  Debenture  Trust
Corporation plc, as trustee (the "Trustee").  Reference herein to the Conditions
(or to any particular  numbered  Condition) shall be to the Terms and Conditions
of the Bonds (or that particular one of them) set out in Schedule 2 to the Trust
Deed.

                                      -44-


The Bonds represented by this Permanent Global Bond were originally  represented
by a Temporary Global Bond. Unless such Temporary Global Bond has been exchanged
in whole for this  Permanent  Global  Bond,  such  Temporary  Global Bond may be
further  exchanged,  on the  terms  and  conditions  set out  therein,  for this
Permanent  Global Bond. If any such exchange occurs  following the date of issue
hereof,  the Principal  Paying Agent shall endorse the Second Schedule hereto to
reflect the increase in the aggregate  principal amount of this Permanent Global
Bond due to each such exchange,  whereupon the principal  amount hereof shall be
increased for all purposes by the amount so exchanged and endorsed.

If, following the date of issue hereof,  any Bonds represented by this Permanent
Global  Bond  are  purchased  by or on  behalf  of  the  Issuer  or  any  of its
Subsidiaries  (as defined in the Conditions)  and surrendered for  cancellation,
the Principal  Paying Agent shall endorse the Second  Schedule hereto to reflect
the decrease in the aggregate principal amount of this Permanent Global Bond due
to such purchase and  cancellation,  whereupon the principal amount hereof shall
be decreased for all purposes by the principal  amount of the Bonds so purchased
and cancelled.

If the Issuer  becomes  obliged to issue Bonds in  definitive  form  pursuant to
Clause 3(C) of the Trust Deed,  this Permanent  Global Bond will be exchangeable
in whole but not in part free of charge  upon the  request of the bearer  hereof
for Bonds in definitive form in the form set out in Schedule 2 to the Trust Deed
only on and subject to the terms and conditions set out in the Trust Deed and as
provided below. If the Issuer has become so obliged to issue Bonds in definitive
form pursuant to Clause 3(C) of the Trust Deed,  this Permanent  Global Bond may
be  exchanged  in whole but not in part at the offices of the  Principal  Paying
Agent in London (or such other place outside the United  States of America,  its
territories,  its possessions and other areas subject to its jurisdiction as the
Trustee may agree) for Bonds in  definitive  form and the Issuer  shall  procure
that the  Principal  Paying  Agent  shall issue and deliver  duly  executed  and
authenticated  Bonds in definitive form (together with the Coupons  appertaining
thereto) in aggregate  principal  amount equal to the  principal  amount of this
Permanent  Global Bond  submitted for  exchange.  On an exchange of the whole of
this Permanent  Global Bond, this Permanent  Global Bond shall be surrendered to
the Principal  Paying Agent and  cancelled.  The Bonds in definitive  form to be
issued  on such  exchange  will be in bearer  form,  serially  numbered,  in the
denominations  of  (pound)10,000  and  (pound)100,000  each  with all  unmatured
Coupons attached.  If the Issuer fails to meet its obligations to issue Bonds in
definitive  form,  this shall be without  prejudice to the Issuer's  obligations
with respect to the Bonds under the Trust Deed and this Permanent Global Bond.

The Issuer  hereby  promises to pay to the bearer  hereof the  principal  amount
shown as outstanding in the fourth column of the Second Schedule hereto (or such
part  thereof or such  greater  amount as may become  repayable  pursuant to the
Conditions) on such date(s) as the said  principal  amount (or part thereof) and
premium,  if any, may become repayable in accordance with the Conditions and the
Trust  Deed and to pay  interest  in arrear on each  Interest  Payment  Date (as
defined  in  Condition  6) on the  principal  amount  outstanding  of the  Bonds
represented by this  Permanent  Global Bond at the rate specified in Condition 6
all subject to and in accordance  with the Conditions and the Trust Deed,  which
shall be binding upon the bearer hereof (as if  references in the  Conditions to
the Bonds and the Bondholders  were references to this Permanent Global Bond and
the  bearer  hereof  respectively  and as if the same had been set out herein in
full mutatis mutandis), except as otherwise provided herein.

                                      -45-


Upon any payment of principal, premium (if any) and/or interest on the Bonds due
to be made  hereunder  details of such payment shall be endorsed by or on behalf
of the Issuer on the First Schedule  hereto in accordance with the provisions of
the Paying  Agency  Agreement (as defined in the Trust Deed) and, in the case of
payments of principal,  the principal amount hereof outstanding shall be reduced
for all  purposes  by the  amounts so paid and  endorsed.  All  payments  of any
amounts  payable and paid to the bearer of this  Permanent  Global Bond shall be
valid and, to the extent of the sums so paid, effectual to satisfy and discharge
the  liability for the moneys  payable  hereon and on the  Definitive  Bonds and
Coupons.

So long as all the Bonds are  represented by this Permanent  Global Bond and the
same is held on behalf of Morgan  Guaranty  Trust Company of New York,  Brussels
office,  as operator of the Euroclear  system  ("EUROCLEAR")  and/or Cedel Bank,
societe anonyme ("CEDEL BANK"),  notices to Bondholders may be given by delivery
to  Euroclear  and Cedel Bank for  communication  by them to the persons for the
time being  shown in the records of  Euroclear  and Cedel Bank (other than Cedel
Bank if Cedel  Bank  shall be an  accountholder  of  Euroclear  and  other  than
Euroclear if Euroclear shall be an accountholder of Cedel Bank) as being holders
of the  Bonds  ("ACCOUNTHOLDERS")  in  which  regard  any  certificate  or other
document  issued by Cedel Bank or Euroclear as to the principal  amount of Bonds
standing to the account of any person  shall be  conclusive  and binding for all
purposes (other than for the purposes of payments in respect thereof,  the right
to which shall be vested,  as against the Issuer and the Trustee,  solely in the
bearer of this Permanent  Global Bond or the Temporary Global Bond in accordance
with and subject to their  respective terms and the terms of the Trust Deed), in
substitution  for publication as required by the  Conditions;  provided that, so
long as the Bonds are listed on the  Luxembourg  Stock Exchange and the rules of
that exchange so require, notices shall also be published in a leading newspaper
having  general   circulation  in  Luxembourg  (which  is  expected  to  be  the
Luxemburger Wort).

Upon any cancellation of any Bond represented by this Permanent Global Bond, the
portion of the principal  amount so cancelled  shall be endorsed by or on behalf
of the Issuer on the Second Schedule hereto, whereupon the outstanding principal
amount  hereof shall be reduced for all purposes by the amount so cancelled  and
endorsed.

In considering the interests of Bondholders  while this Permanent Global Bond is
held on behalf of Euroclear  and/or  Cedel Bank,  the Trustee may have regard to
any  information  provided  to it by such  clearing  system  as to the  identity
(either  individually or by category) of its accountholders  with entitlement to
this  Permanent  Global  Bond  and  may  consider  such  interests  as  if  such
accountholders  were the  holders  of the Bonds  represented  by this  Permanent
Global Bond.

For so long as all the Bonds are  represented by this Permanent  Global Bond, no
drawing of Bonds will be  required  under  Condition  8(b) in the event that the
Issuer exercises its call option hereunder in respect of less than the aggregate
principal  amount of Bonds  outstanding at such time. Bonds will be selected for
redemption  in  accordance  with the rules and  procedures  from time to time of
Euroclear and Cedel Bank.

                                      -46-


The  Bondholders'  put option in  Condition 14 may be exercised by the holder of
this  Permanent  Global Bond giving notice to the Principal  Paying Agent of the
principal  amount of Bonds in  respect  of which the  option  is  exercised  and
presenting  this Permanent  Global Bond for  endorsement of exercise  within the
time limits specified in Condition 14.

This Permanent Global Bond shall become void unless presented for payment within
ten years (in  respect of payment of  principal  and  premium  (if any)) or five
years (in respect of payment of interest),  respectively, from the Relevant Date
(as  defined in  Condition  9) for  payment in respect  thereof,  subject to the
provisions  of  Condition 7. All  references  in this  Permanent  Global Bond to
Euroclear or Cedel Bank shall be deemed to include such  substitute or successor
clearing system as may be approved by the Trustee from time to time.

This  Permanent  Global Bond shall not become  valid for any purpose  unless and
until the Certificate of Authentication  hereon has been signed by an authorised
signatory of the Principal Paying Agent.

This Permanent  Global Bond is governed by, and shall be construed in accordance
with, the laws of England.

IN WITNESS whereof the Issuer has caused this Permanent Global Bond to be signed
manually or in facsimile by a Director of the Issuer on its behalf.

2.   STATUS AND BOND POLICY

     (a) Status

     The Bonds and Coupons constitute direct,  unconditional and (subject to the
provisions  of Condition 5) unsecured  obligations  of the Company and rank pari
passu and without any preference among  themselves.  The payment  obligations of
the Company under the Bonds and the Coupons shall, subject as aforesaid and save
for such exceptions as may be provided by applicable  legislation,  at all times
rank  at  least   equally  with  all  its  present  and  future   unsecured  and
unsubordinated obligations.

     (b) Bond Policy

     The Bonds have the  benefit of the Bond  Policy  (which has been  issued by
AMBAC pursuant to an insurance and indemnity  agreement dated 15th December 1997
between the Company and AMBAC) (the "Insurance and Indemnity  Agreement")  under
which AMBAC unconditionally and irrevocably guarantees Insured Amounts which are
Due for Payment subject only to the Trustee being required to make a claim under
and in accordance with the Bond Policy,  all as more  particularly  described in
the Bond Policy.

     The terms of the Bond Policy provide that amounts of principal on any Bonds
which  have  become   immediately   due  and  payable   (whether  by  virtue  of
acceleration,  prepayment  or  otherwise)  other than on the relevant  Scheduled
Payment  Date will not be treated as Insured  Amounts  which are Due for Payment
unless AMBAC in its sole discretion  elects so to do by notice in writing to the
Trustee.  If no such election is made,  AMBAC will continue to be liable to make
payments  in respect of the Bonds  pursuant  to the Bond  Policy on the dates on
which such payments  would have been required to be made as if the Bonds had not
become immediately due and payable.

to any of its  shareholders  if (A) (i) no Issuer  Event of Default has occurred
and is  continuing,  and (ii) no Issuer  Event of Default  will  result from the

          Company shall  thereafter  cease to be bound by the provisions of this
          Condition.

5.   NEGATIVE PLEDGE

     So long as any of the Bonds  remain  outstanding,  the Company  will ensure
that no Relevant  Indebtedness of the Company or of any PES Subsidiary or of any
other  person  and no  guarantee  by the  Company or any PES  Subsidiary  of any
Relevant Indebtedness of any other person will be secured by a Security Interest
upon,  or with respect to, any of the present or future  business,  undertaking,
assets or revenues  (including  any uncalled  capital) of the Company or any PES
Subsidiary unless the Company shall,  before or at the same time as the creation
of the Security Interest, take any and all action necessary to ensure that:

          (a) all  amounts  payable by it under the Bonds,  the  Coupons and the
     Trust Deed are secured equally and rateably with the Relevant  Indebtedness
     or guarantee of Relevant indebtedness, as the case may be, by such Security
     Interest; or

          (b) such other  Security  Interest or guarantee  or other  arrangement
     (whether or not including the giving of a Security Interest) is provided in
     respect of all amounts payable by the Company under the Bonds,  the Coupons
     and  the  Trust  Deed  either  (i) as the  Trustee  shall  in its  absolute
     discretion  deem not  materially  less  beneficial  to the interests of the
     Bondholders or (ii) as shall be approved by an Extraordinary Resolution (as
     defined in the Trust Deed) of the Bondholders.

save  that  the  Company  or any  PES  Subsidiary  may  create,  assume  or have
outstanding a Security Interest in respect of any Relevant  Indebtedness  and/or
any  guarantees  given by the  Company or any PES  Subsidiary  in respect of any
Relevant  Indebtedness  of any  person  (without  the  obligation  to  provide a
Security  Interest or guarantee or other  arrangement  in respect of all amounts
payable  by the  Company  under the  Bonds,  the  Coupons  and the Trust Deed as
aforesaid) where (1) such Relevant  Indebtedness has an initial maturity falling
not  earlier  than  31st  December  2022 and is of a  maximum  aggregate  amount
outstanding at any time not exceeding the greater of  (pound)200,000,000  and 20
per cent, of the Capital and Reserves,  (2) such  Security  Interest  existed in
respect of a company that  becomes a PES  Subsidiary  of the Company  after 11th
December  1997  (provided  that  such  Security  Interest  was  not  created  in
contemplation of such company becoming a PES Subsidiary and the principal amount
secured  at  the  time  of  such  company  becoming  a  PES  Subsidiary  is  not
subsequently  increased),  (3) such  Security  Interest  existed  on the date of
original issue of the Bonds or (4) with respect to Security Interests  described

                                      -67-


in (2) and (3),  such Security  Interests are extended,  renewed or replaced (or
extensions,  renewals or replacements for such Security Interests are themselves
extended,  renewed or replaced) to secure Relevant  Indebtedness in an aggregate
principal  amount which does not exceed the  aggregate  principal  amount of the
Relevant  Indebtedness secured by the Security Interest so extended,  renewed or
replaced, provided that such extension, renewal or replacement Security Interest
is limited to all or part of the same  property or assets  which were subject to
the Security  Interest so extended,  renewed or  replaced,  as such  property or
assets may be improved from time to time.

6.   INTEREST

     The Bonds bear interest  ("Scheduled  Interest")  from (and including) 15th
December  1997  (the  "Issue  Date")  at the  rate of 7.25 % per  annum  payable
annually  in arrear on 15th  December  in each year (each an  "Interest  Payment
Date").  Each Bond will cease to bear  Scheduled  Interest from the due date for
redemption  thereof,  unless,  upon due  presentation,  payment of  principal or
premium (if any) is  improperly  withheld or refused.  In such event,  each Bond
shall  continue to bear interest  ("Default  Interest") at such rate both before
and after  judgment  until  whichever is the earlier of (i) the day on which all
sums due in respect of such Bond up to that day are  received by or on behalf of
the  relevant  holder  and (ii) the day  seven  days  after the  Trustee  or the
Principal Paying Agent has notified  Bondholders in accordance with Condition 18
of receipt  of all sums then due in respect of all the Bonds up to that  seventh
day except to the extent that there is failure in the subsequent  payment to the
relevant  holder  under these Terms and  Conditions.  If  Scheduled  Interest or
Default  Interest  is required  to be  calculated  for a period of less than one
year,  it will be  calculated  on the basis of a 360 day year  consisting  of 12
months of 30 days each and, in the case of an  incomplete  month,  the number of
days elapsed.

     DEFAULT INTEREST DOES NOT ACCRUE ON SCHEDULED INTEREST OR DEFAULT INTEREST.
THE PAYMENT OF DEFAULT INTEREST IS NOT GUARANTEED UNDER THE BOND POLICY.

7.   PAYMENTS

     Payments of principal, premium (if any) or interest in respect of the Bonds
will be made against  surrender of Bonds or, in the case of payments of interest
due on an Interest Payment Date, against surrender of Coupons,  at the specified
office of any Paying  Agent by a sterling  cheque  drawn on, or at the option of
the holder,  by transfer to a sterling  account  maintained  by the payee with a
branch of a bank in the City of  London,  subject  in all cases to any fiscal or
other laws and  regulations  applicable  in the place of  payment,  but  without
prejudice to the provisions of Condition 9.

                                     -68-


     Upon the due date for redemption of any Bond, unmatured Coupons relating to
such Bond  (whether or not  attached)  shall become void and no payment shall be
made in respect of them. Where any Bond is presented for redemption  without all
unmatured  Coupons  relating to it,  redemption  shall be made only  against the
provision of such indemnity as the Company and AMBAC may require.

     If the due date for  redemption  of any  Bond is not 15th  December  in any
year,  interest  accrued in respect of such Bond from (and  including)  the last
preceding 15th December will be paid only against  presentation and surrender of
such Bond.

     If the due date for  payment of any amount in respect of any Bond or Coupon
is not a business day, then the holder  thereof shall not be entitled to payment
of the  amount  due until the next  following  business  day nor to any  further
interest or other  payment in respect of such delay.  The  expression  "business
day" in this  Condition  means a day other  than a  Saturday  or Sunday on which
banks are open (for  business in the place where the Bond or Coupon is presented
and,  in the case of payment by  transfer  to a sterling  account as referred to
above, in the City of London.

     The names of the  initial  Principal  Paying  Agent  and the other  initial
Paying  Agents and their  initial  specified  offices  are set out at the end of
these Terms and Conditions. The Company reserves the right, subject to the prior
written  approval of the Trustee and the Controlling  Party, at any time to vary
or terminate the  appointment  of any Paying Agent and to appoint  additional or
other  Paying  Agents  provided  that it will at all times  maintain  two Paying
Agents having  specified  offices in separate  European  cities  approved by the
Trustee,  one of which, so long as any of the Bonds are listed on the Luxembourg
Stock Exchange and the rules of the Luxembourg Stock Exchange so require,  shall
be Luxembourg.  Notice of any such termination or appointment and of any changes
in the specified  offices of the Paying Agents will be given to the  Bondholders
in accordance  with  Condition 18 as soon as  practicable  thereafter.  UNDER NO
CIRCUMSTANCES  WILL  INTEREST BE PAYABLE IN THE UNITED  STATES OF AMERICA OR ANY
POSSESSION OF THE UNITED STATES OF AMERICA.

8.   REDEMPTION AND PURCHASE

          (a) Unless previously redeemed or purchased and cancelled, the Company
     will redeem the Bonds on 15th December 2022 at their principal amount.

          (b) The Company  may,  having  given not less than 30 nor more than 45
     days'  notice  in  accordance  with  Condition  18 (which  notice  shall be
     trrevocable),   redeem   the  whole  or  part  (in   principal   amount  of
     (pound)5,000,000  or integral  multiples  thereof) of the Bonds at any time
     prior to 15th  December  2022 at a price  which  shall be the higher of the
     following, together with Scheduled Interest accrued up to and including the
     date of redemption:

          (i) par; and

          (ii) that price (the  "Redemption  Price")  expressed  as a percentage
          (rounded to three decimal places,  0.0005 being rounded  upwards),  at
          which the Gross  Redemption  Yield  (calculated as described below) on
          the  Bonds,  if they were to be  purchased  at such price on the third
          dealing  day prior to the due date for  redemption,  would be equal to
          the Gross  Redemption  Yield on such dealing day of 8% Treasury  Stock
          due 7th June  2021 or, if such  stock is no  longer in issue,  of such
          other United Kingdom government stock as the Trustee,  with the advice
          of three brokers or market-makers  operating in the gilt-edged market,

                                      -69-


          shall  determine to be appropriate  (the  "Reference  Stock"),  on the
          basis of the middle market price of the Reference Stock  prevailing at
          11:00 am on such dealing  day, as  determined  by Credit  Suisse First
          Boston  (Europe)  Limited  (or such other  person as the  Trustee  may
          approve).  Any  reference in these Terms and  Conditions  to principal
          shall be deemed to include any sum payable as the Redemption Price.

               Notices of redemption will specify the date fixed for redemption,
          the  applicable   Redemption   Price  and,  in  the  case  of  partial
          redemption,  the  aggregate  principal  amount  of  the  Bonds  to  be
          redeemed,  the serial numbers of the Bonds called for redemption,  the
          serial numbers of the Bonds  previously  called for redemption and not
          presented for payment and the aggregate  principal amount of the Bonds
          to remain  outstanding  after the  redemption.  Upon the expiry of any
          notice of  redemption  the Company  shall be bound to redeem the Bonds
          called for redemption at the applicable  Redemption Price. Any partial
          redemption of the Bonds shall be on the basis of selection by drawings
          (the  method of such  drawings  to be  approved  by the Trustee in its
          absolute discretion).

          The "Gross Redemption Yield" on the Bonds and the Reference Stock will
          be  expressed  as a  percentage  and will be  calculated  on the basis
          indicated  by the Joint  Index  and  Classification  Committee  of the
          Institute  and Faculty of  Actuaries as reported in the Journal of the
          Institute  of  Actuaries,  Vol.  105 Part 1, 1978,  page 18 or on such
          other basis as the Trustee may approve.

               (c) If, as a result of any change in, or  amendment  to, the laws
          or regulations of the United Kingdom or any political  subdivision of,
          or any authority in, or of, the United Kingdom having power to tax, or
          any change in the application or official  interpretation of such laws
          or regulations, which change or amendment becomes effective after 11th
          December  1997,  the  Company  has  or  will  become  obliged  to  pay
          additional amounts as provided or referred to in Condition 9 (and such
          amendment or change has been  evidenced by the delivery by the Company
          to the Trustee and AMBAC (who shall, in the absence of manifest error,
          accept such certificate and opinion as sufficient evidence thereof) of
          a  certificate  signed by a Director  of the  Company on behalf of the
          Company   stating   that  such   amendment   or  change  has  occurred
          (irrespective  of whether such amendment or change is then effective),
          describing the facts leading  thereto and stating that such obligation
          cannot be avoided by the Company taking reasonable  measures available
          to it) the Company may at its  option,  having  given not less than 30
          nor more than 60 days notice to the  Bondholders  in  accordance  with
          Condition 18 (which notice shall be irrevocable), redeem all the Bonds
          (other than Bonds in respect of which the  Company  shall have given a
          notice of  redemption  pursuant to Condition  8(b) prior to any notice
          being given under this  Condition  8(c)),  but not some only, at their
          principal amount together with interest accrued to (but excluding) the
          date of  redemption,  provided that no notice of  redemption  shall be
          given  earlier  than 90 days  before  the  earliest  date on which the
          Company would be required to pay the additional amounts were a payment
          in respect of the Bonds than due.

                                      -70-

          OF THE AMOUNTS PAYABLE BY THE COMPANY FOLLOWING AN EARLY REDEMPTION OF
          THE BONDS PURSUANT TO CONDITION 8(B) OR (C). AMBAC WILL NOT BE OBLIGED
          UNDER ANY  CIRCUMSTANCES TO ACCELERATE  PAYMENT UNDER THE BOND POLICY;
          IF IT DOES SO, THE AMOUNT  PAYABLE  WILL BE THE PAR VALUE OF THE BONDS
          TOGETHER  WITH ACCRUED  INTEREST AS AT THE DATE OF  ACCELERATION.  ANY
          AMOUNT  OF  PRINCIPAL  ON  THE  BONDS  IN  EXCESS  OF PAR  WLL  NOT BE
          GUARANTEED BY AMBAC UNDER THE BOND POLICY.

               (d)  The  Company  or  any of its  Subsidiaries  may at any  time
          purchase  or  otherwise  acquire  Bonds  provided  that all  unmatured
          Coupons are attached thereto or are surrendered therewith at any price
          in the open  market or  otherwise.  If  purchases  are made by tender,
          tenders must be available to all Bondholders alike.

               (e) All Bonds which are redeemed pursuant to this Condition shall
          be cancelled  (together with all relative  unmatured  Coupons attached
          thereto or surrendered  therewith) and accordingly may not be reissued
          or resold.  Bonds  purchased  by or on behalf of the Company or any or
          its  Subsidiaries may be held or reissued or resold or surrendered for
          cancellation.

          Company  shall be made without  withholding  or  deduction  for, or on
          account  of,  any  present or future  taxes,  duties,  assessments  or
          governmental charges of whatever nature ("Taxes") imposed or levied by
          or on behalf of the United Kingdom,  or any political  subdivision of,
          or authority in, or of, the United Kingdom having power to tax, unless
          the  withholding or deduction of the Taxes is required by law. In that
          event,  the  Company  will  pay  such  additional  amounts  as  may be
          necessary  in order that the net amounts  received by the  Bondholders
          and  Couponholders  after the withholding or deduction shall equal the
          respective  amounts which would have been receivable in respect of the
          Bonds  or,  as  the  case  may  be.  Coupons  in  the  absence  of the
          withholding or deduction;  except that no additional  amounts shall be
          payable in relation to any payment in respect of any Bond or Coupon:

                    (i) to, or to a third  party on behalf  of, a holder  who is
               liable to the Taxes in respect of the Bond or Coupon by reason of
               his having some connection with the United Kingdom other than the
               mere holding of the Bond or Coupon; or

                    (ii) presented for payment in the United Kingdom; or

                                      -71-


                    (iii) to, or to a third  party on  behalf  of, a holder  who
               would not be liable or subject to the withholding or deduction by
               making a declaration of  non-residence or other similar claim for
               exemption to the relevant tax authority; or

                    (iv)  presented  for  payment  more  than 30 days  after the
               Relevant  Date  except to the extent  that the holder  would have
               been  entitled to additional  amounts on presenting  the same for
               payment on the last day of the period of 30 days.

     to, any of the present or future business,  undertaking, assets or revenues
     (including  any  uncalled  capital)  of  Northern  Electric  plc or any PES

          Interest; or

               (b)  such  other   Security   Interest  or   guarantee  or  other
          arrangement  (whether  or  not  including  the  giving  of a  Security

          under the Bonds,  the Coupons,  the Trust Deed and the  Insurance  and

                                     -73-


     save that Northern  Electric plc or any PES  Subsidiary  may create or have
     outstanding  a  Security  Interest  in  respect  of  any  of  its  Relevant
     Indebtedness  and/or any guarantees  given by Northern  Electric plc or any
     PES Subsidiary in respect of any Relevant  Indebtedness of any other person
     (without  the  obligation  to provide a Security  Interest or  guarantee or
     other  arrangement in respect of the Bonds, the Coupons and the Trust Deed)
     where such Relevant Indebtedness has an initial maturity rating not earlier
     than 31st December 2022 and is of maximum  aggregate amount  outstanding at
     any time not exceeding the greater (pound)50,000,000 and 20 per cent of the
     Northern Consolidated Tangible Net Worth (as defined below).

          For the purposes of this paragraph:

          (1) "Northern Consolidated Tangible Net Worth" means at any particular
     time the aggregate of the amount paid up on Northern  Electric plc's issued
     share  capital  and the  consolidated  distributable  and  nondistributable
     reserves of the  Northern  Group (as shown in the most  recently  published
     audited consolidated financial statements of the Northern Group), after:

               (i)  deducting  the total of any debit  balance on the profit and
          loss account and the book value of any intangible assets including but
          not limited to goodwill;

               (ii) excluding any minority interests in Subsidiary Undertakings;
          and

               (iii) adding the amount shown in respect of deferred taxation;

     but adjusted as may be necessary in respect of any variation in the paid-up
     share capital or share premium account of the Northern Group since the date
     of that balance  sheet and further  adjusted as may be necessary to reflect
     any  change  since  the  date  of  that  balance  sheet  in the  Subsidiary
     Undertakings comprising the Northern Group.

          A report by the Auditors as to the amount of the Northern Consolidated
     Tangible  Net Worth at any given time  shall,  in the  absence of  manifest
     error, be conclusive and binding on all parties.

          (2) "Northern  Group" means  Northern  Electric plc and its Subsidiary
     Undertakings.

          (3)  "Subsidiary  Undertaking"  shall have the meaning  given to it by
     Section 258 of the Companies  Act 1985 (but shall exclude any  undertakings
     (as defined in the Companies  Act 1985) whose  accounts are not included in
     the  then  latest  published  audited  consolidated  accounts  of  Northern
     Electric plc, nor (in the case of an  undertaking  which has first become a
     subsidiary  undertaking of a member of the Northern Group since the date as
     at which any such audited  accounts were prepared)  would its accounts have
     been so  included  or  consolidated  if it had become so on or before  that
     date.
                                     -74-


          (4) Any reference to an obligation  being  guaranteed  shall include a
     reference to any indemnity being given in respect of the obligation.

12.  ISSUER EVENTS OF DEFAULT

     If:

          (a)  default is made in the  payment of any  principal  or premium (if
     any) in respect of any Bond  pursuant to  Condition 8, or for a period of 5
     days or more in the payment of any interest due in respect of the Bonds; or

          (b)  the  Company  fails  to  perform  or  observe  any of  its  other
     obligations, covenants, conditions or provisions under the Bonds, the Trust
     Deed or the  Insurance  and  Indemnity  Agreement  and  (except  where  the
     Controlling  Party shall have  certified  to the Company in writing that it
     considers  such  failure  to be  incapable  of remedy in which case no such
     notice or continuation  as is hereinafter  mentioned will be required) such
     failure  continues  for the period of 60 days (or such longer period as the
     Trustee  may,  with the  approval of the  Controlling  Party,  permit) next
     following the service by the Trustee on the Company of notice requiring the
     same to be remedied; or

          (c) (i) any other  Indebtedness  For Borrowed  Money of the Company or
     any  Principal  Subsidiary  becomes due and  repayable  prior to its stated
     maturity by reason of an event of default  (however  described) or (ii) any
     such  Indebtedness  For Borrowed Money (including as aforesaid) is not paid
     when due or (iii) the Company or any Principal Subsidiary fails to pay when

     any  Indebtedness  For  Borrowed  Money of any person or any  guarantee  or
     indemnity  of  Indebtedness  For  Borrowed  Money  of  any  person  becomes
     enforceable by reason of default in relation thereto and steps are taken to
     enforce  such  security  save in any such case  where  there is a bona fide
     dispute as to whether the relevant  Indebtedness  For Borrowed Money or any
     such guarantee or indemnity as aforesaid shall be due and payable, provided
     that the aggregate  amount of the relevant  Indebtedness For Borrowed Money
     in respect of which any one or more of the events  mentioned  above in this
     sub-paragraph  (c) has or have occurred equals or exceeds  whichever is the
     greater of  (pound)25,000,000  or its  equivalent in other  currencies (as
     determined by the Trustee) and two per cent of the Capital and Reserves and
     such event shall continue  unremedied or unwaived for more than 14 days (or
     such  longer  grace  period as may have  been  originally  provided  in the
     applicable instrument) and the time for payment of such amount has not been
     expressly  extended  (until such time as any payment  default is  remedied,
     cured or waived). For the purposes of this sub-paragraph (c), "Indebtedness
     for Borrowed Money" shall exclude Project Finance Indebtedness; or

     the  purposes  of  amalgamation,  merger,  consolidation,   reorganisation,
     reconstruction or other similar arrangement on terms previously approved in
     writing by the  Controlling  Party or (where the  Controlling  Party is the
     Trustee) by an Extraordinary Resolution of the Bondholders; or

          (f) any order shall be made by any competent  court or any  resolution
     shall be passed and not validly revoked or cancelled within 30 days for the
     winding up or dissolution of a Principal Subsidiary,  save for the purposes

     other  similar  arrangement  (i)  not  involving  or  arising  out  of  the
     insolvency  of such  Principal  Subsidiary  and under which all the surplus
     assets of such Principal  Subsidiary are  transferred to the Company or any
     of its other  Subsidiaries  (not being an Excluded  Subsidiary) or (ii) the
     terms of which have  previously been approved in writing by the Controlling

     insolvency of the Company or such Principal  Subsidiary and under which all
     or  substantially  all of its  assets are  transferred,  in the case of the
     Company,  to a  Subsidiary  of the  Company  or, in the case of a Principal
     Subsidiary,  to the Company or another  Subsidiary  of the Company (in each
     case not being an  Excluded  Subsidiary)  or to a  transferee  which is, or
     immediately  upon such  transfer  becomes,  a Principal  Subsidiary or (ii)
     under which all or  substantially  all of its assets are  transferred  to a
     third party or parties (whether a Subsidiary or Subsidiaries of the Company
     or not) for full consideration by the Company or a Principal  Subsidiary on
     an arm's  length  basis or (iii) the terms of which  have  previously  been
     approved  in writing  by the  Controlling  Party or (where the  Controlling
     Party is the Trustee) by an  Extraordinary  Resolution  of the  Bondholders
     provided  that (A) if  Northern  Electric  plc shall cease to hold or shall
     transfer  the PES  Licence  (other  than where the PES  Licence is revoked,
     terminated  or  surrendered  in the  circumstances  envisaged  by paragraph
     (i)(a), (b) or (c) of the definition of Restructuring  Event in Condition 3
     and  such  revocation,  termination  or  surrender  does not  constitute  a
     Restructuring  Event  pursuant to  paragraph  (i) of such  definition)  the
     Company  shall  be  deemed  to  have  ceased  to  carry  on  the  whole  or
     substantially  the whole of its business (and neither of exceptions (i) and
     (ii) above shall  apply)  unless the  transferee  of the PES Licence is the
     Company or a Subsidiary of the Company (not being an Excluded  Subsidiary),
     at least 51% of the ordinary  share  capital of which is owned  directly or
     indirectly  by the Company (the "NE  Transferee")  and in either such event
     all references in these Terms and Conditions to Northern Electric plc shall
     hereafter be deemed to be  references  to the NE  Transferee;  or (B) if an
     Excluded Licence is granted to any person, the transfer by the Company or a
     Principal  Subsidiary of the business relating to such Excluded Licence for
     full consideration on an arms length basis and the consequent  cessation at
     such business of the Company or such Principal  Subsidiary  shall be deemed
     not to fail within this paragraph (g); or

                                     -76-


          (h) the Company or any  principal  Subsidiary  shall  suspend or shall

     process  shall be  levied  or  enforced  upon or sued out  against,  or any
     encumbrancer  shall take possession of, the whole or a substantial  part of
     the assets of any of them and in any of the foregoing  cases it or he shall
     not be paid out or discharged  within 20 days (or such longer period as the
     Trustee may in its absolute discretion permit);

and,  in the case of  sub-paragraphs  (b),  (c) and (f) to (i)  (inclusive)  the
Controlling  Party shall have certified in writing that the relevant event is in
its opinion  materially adverse to (1) where the Controlling Party is AMBAC, the
interests  of AMBAC or (2)  where  the  Controlling  Party is the  Trustee,  the
interests of the Bondholders,  the Controlling  Party may at its discretion (and
if the  Controlling  Party is the  Trustee it shall on the request in writing of
the  holders  of at least one  quarter  in  principal  amount of the Bonds  then
outstanding  or upon being so directed  by an  Extraordinary  Resolution  of the
Bondholders),  by notice in writing to the Company  declare  that the Bonds are,
and  they  shall  accordingly  thereby  forthwith  become,  immediately  due and
repayable at their principal  amount together with accrued interest (as provided
in the Trust Deed), provided always that the giving of any notice in relation to
any  Issuer  Event of  Default  shall  not  operate  as a  waiver  of any of the
Controlling  Party's rights  (including  the right to gave a further  notice) or
prevent  the  Controlling  Party  from  giving a further  notice  in the  manner
referred  to above in  relation  to that  Issuer  Event of  Default  at any time
thereafter, and provided further that for the purposes of sub-paragraphs (c) and
(f) to (i) (inclusive), the term "Principal Subsidiary" shall include each of CE
Electric UK Holdings, CE Electric UK plc and Northern Electric plc.

     So long as any of the Bonds remain outstanding the Company will,  forthwith
upon  becoming  aware of any issuer  Event of  Default,  give  notice in writing
thereof to the Trustee and to AMBAC.

     For the  purpose of  sub-paragraph  (i)  above,  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 (as referred
to in the PES Licence)  may from time to time  determine by notice in writing to
the Secretary of State (as referred to in the PES Licence) and Northern Electric
plc.
                                     -77-


     Neither  the  Company nor any  Principal  Subsidiary  shall be deemed to be
unable to pay its debts for the purposes of sub-paragraph  (i) above if any such
demand as is mentioned in Section  123(1)(a) of the Insolvency Act 1986 is being
contested in good faith by the Company or the relevant Principal Subsidiary with
recourse to all appropriate measures and procedures.

     WHILE  AMBAC IS THE  CONTROLLING  PARTY,  NEITHER THE  BONDHOLDERS  NOR THE
TRUSTEE  WILL HAVE ANY RIGHT TO CALL FOR  REPAYMENT OF THE BONDS  FOLLOWING  THE
OCCURRENCE OF AN ISSUER EVENT OF DEFAULT.

13.  AMBAC EVENTS OF DEFAULT

     (i)  Each of the following events is an AMBAC Event of Default:

          on the date stipulated in the Bond Policy;

          (b) AMBAC  disclaims,  disaffirms,  repudiates  and/or  challenges the

          do so;

          (c)  a  court  or   competent   jurisdiction   enters   a  final   and
          non-appealable  order,  judgment  or decree for the winding up, or the
          appointment   of   an   administrator   or   receiver   including   an
          administrative receiver or manager), of AMBAC (or, as the case may be,
          of a material part of its Property or assets); or

     AMBAC:

          (1) presents any petition or takes any proceedings for the winding up,
     or  the  appointment  or  an  administrator   or  receiver   (including  an

     its creditors; or

IN THE BONDS  BECOMING  REPAYABLE  EARLY.  FOLLOWING  AN AMBAC EVENT OF DEFAULT,
AMBAC SHALL CEASE TO BE THE CONTROLLING PARTY.

                                      -78-


14.  RESTRUCTURING EVENT

               (a) (i) If,  at any time  following  the  occurrence  of an AMBAC
          Event of  Default,  while  any of the  Bonds  remains  outstanding,  a
          Restructuring  Event occurs and prior to the commencement of or during
          the Restructuring Period an Independent  Financial Adviser (as defined
          below)  shall  have  certified  in writing  to the  Trustee  that such
          Restructuring Event will not be or is not, in its opinion,  materially
          prejudicial  to  the  interests  of  the  Bondholders,  the  following
          provisions of this Condition shall cease to have any further effect in
          relation to such Restructuring Event.

          (ii) if, at any time  following  the  occurrence  of an AMBAC Event of
     Default while any of the Bonds remains  outstanding,  a Restructuring Event
     occurs and (subject to (a)(i) above):

               (A) within the Restructuring Period, either:

                    (i) if at the time such Restructuring Event occurs there are
               Reference Rated Securities, a Rating Downgrade in respect of such
               Restructuring Event also occurs; or

                    (ii)  if  at  such  time  there  are  not  Reference   Rated
               Securities, a Negative Rating Event also occurs; and

               (B) an  Independent  Financial  Adviser  shall have  certified in
               writing to the Trustee that such  Restructuring  Event is, in its
               opinion,   materially   prejudicial   to  the  interests  of  the
               Bondholders (a "Negative Certification"),

     then,  unless  at any time the  Company  shall  have  given a notice  under
     Condition  8(b) or Condition  8(c), in each case expiring  prior to the Put
     Date (as defined below), the holder of each Bond will, upon the giving of a
     Put Event Notice (as defined below),  have the option (the "Put Option") to
     require  the Company to redeem or, at the option of the  Company,  purchase
     (or procure  the  purchase  of) that Bond on the Put Date at its  principal
     amount  together with (or, where  purchased,  together with an amount equal
     to) interest (if any) accrued to (but excluding) the Put Date.

     A Restructuring  event shall be deemed not to be materially  prejudicial to
the interests or the Bondholders it,  notwithstanding the occurrence of a Rating
Downgrade or a Negative Rating Event, the rating assigned to the Reference Rated
Securities  by any Rating Agency is  subsequently  increased to, or, as the case
may be, there is assigned to the Reference Rated Securities by any Rating Agency
an  Investment  Grade  Rating or, in the event that the rating  assigned  to the
Reference  Rated  Securities  immediately  prior to the occurrence to the Rating
Downgrade or Negative Rating Event was not an Investment  Grade Rating,  if such
rating is  restored,  in either case prior to any Negative  Certification  being
issued.

                                      -79-


     Any  certificate  by an  Independent  Financial  Adviser as aforesaid as to
whether  or  not,  in  its  opinion,   any  Restructuring  Event  is  materially
prejudicial to the interest of the Bondholders shall, in the absence of manifest
error,  be  conclusive  and  binding  on  the  Trustee,   the  Company  and  the
Bondholders.  For the  purposes of this  Condition,  an  "Independent  Financial
Adviser" means a financial  adviser appointed by the Company and approved by the
Trustee (such  approval not to be  unreasonably  withheld or delayed) or, it the
Company shall not have  appointed  such an adviser within 21 days after becoming
aware  of the  occurrence  to  such  Restructuring  Event  and  the  Trustee  is
indemnified to its satisfaction against the costs of such adviser,  appointed by
the Trustee following consultation with the Company.

     A Rating  Downgrade or a Negative  Rating Event or a  non-Investment  Grade
Rating  shall be deemed not to have  occurred  as a result of or in respect of a
Restructuring Event if the Rating Agency making the relevant reduction in rating
or, where applicable, declining to assign an Investment Grade Rating as provided
in this Condition does not announce or publicly confirm or inform the Trustee in
writing at its request that the  reduction  or, where  applicable,  declining to
assign a rating  of at least  investment  grade was the  result,  in whole or in
part,  of any event or  circumstance  comprised in or arising as a result of the
applicable Restructuring Event.

     The  Trust  Deed  provides  that the  Trustee  is under  no  obligation  to
ascertain  whether a  Restructuring  Event,  a Negative  Rating Event,  a Rating
Downgrade or any event which could lead to the occurrence of or could constitute
a  Restructuring  Event,  a  Negative  Rating  Event or a Rating  Downgrade  has
occurred and until it shall have actual  knowledge or express notice pursuant to
the Trust Deed to the  contrary  the Trustee  may assume  that no  Restructuring
Event, Negative Rating Event, Rating Downgrade or other such event has occurred.

          (b)  Promptly  upon the  Company  becoming  aware that a Put Event (as
     defined in  Condition 3) has  occurred,  and in any event not later than 14
     days after the  occurrence of a Put Event,  the Company  shall,  and at any
     time upon the Trustee  becoming  similarly so aware the Trustee may, and if
     so requested by the holders of at least  one-quarter in principal amount of
     the Bonds then outstanding shall, give notice (a "Put Event Notice") to the
     Bondholders  in accordance  with  Condition 18 specifying the nature of the
     Put Event and the procedure for exercising the Put Option.

          (c) To exercise the Put Option, the holder of a Bond must deliver such
     Bond to the  specified  office  of any  Paying  Agent,  on a day which is a
     business day (as defined in Condition 7) in London and in the place of such
     specified  office  falling  within the period (the "Put Period") of 45 days
     after  that on which a Put Event  Notice is  given,  accompanied  by a duly
     completed  and signed  notice of  exercise  in the form (for the time being
     current)  obtainable from any specified  office of any Paying Agent (a "Put
     Notice") and in which the holder may specify a bank account  complying with
     the  requirements  of Condition 7 to which payment is to be made under this
     Condition.  Each  Bond  should  be  delivered  together  with  all  Coupons
     appertaining  thereto  maturing  after the day (the "Put  Date")  being the
     fifteenth day after the date of expiry of the Put Period, failing which any
     such  missing  Coupon  will  become  void and no  payment  shall be made in
     respect  of it. The Paying  Agent to which  such Bond and Put  Notices  are
     delivered  shall  issue  to the  Bondholder  concerned  a  non-transferable
     receipt in respect of the Bond so delivered. Payment in respect of any Bond

                                      -80-


     so delivered  shall be made, if the holder duly specifies a bank account in
     the Put Notice to which  payment is to be made on the Put Date, by transfer
     to that bank account and, in every other case, on or after the Put Date, in
     each  case  against  presentation  and  surrender  or (as the  case may be)
     endorsement  of such receipt at any  specified  office of any Paying Agent,
     subject in any such case as  provided  in  Condition  7. A Put Notice  once
     given shall be  irrevocable.  For the purposes of Conditions 10, 12, 15, 17
     and 19 receipts  issued  pursuant to this Condition  shall be treated as if
     they were Bonds. The Company shall redeem or, at the option of the Company,
     purchase (or procure the purchase of) the relevant  Bond on the  applicable
     Put Date unless previously redeemed or purchased.

     THE  BOND  POLICY  DOES  NOT  GUARANTEE  THE  PAYMENT  OF ANY  SUMS  DUE TO
BONDHOLDERS UPON EXERCISE OF THE PUT OPTION PURSUANT TO CONDITION 14.

15.  ENFORCEMENT

          (a)  Limitation  on  Bondholders:  Save as  provided  below,  only the
     Trustee may pursue the remedies  available  under  general law or under the
     Trust Deed to enforce the rights of the Bondholders and  Couponholders  and
     no such holder  will be  entitled  to proceed  against the Company or AMBAC
     unless the Trustee, having become bound to act in accordance with the terms
     of the Trust Deed,  fails to do so and such failure is  continuing.  If, in
     connection with any insolvency,  bankruptcy,  administration,  dissolution,
     liquidation or analogous  procedure  relating to the Company,  a payment on
     the Bonds by the  Company is claimed to be or is avoided as a  preferential
     transfer,  AMBAC may (provided  that AMBAC is then the  Controlling  Party)
     direct all  matters  relating to such claim or  avoidance  on behalf of the
     Trustee, the Bondholders and the Couponholders.

          (b) Enforcement  Proceedings:  At any time after amounts in respect of
     princtpai  of and  interest on the Bonds shall have become due and payable,
     the Trustee may, at its discretion  and without  further notice but subject
     as mentioned below, take such proceedings against:

               (i) the Company as it may think fit to enforce the  provisions of
          the Trust Deed; and/or

               (ii) AMBAC as it may think fit to enforce the  provisions  of the
          Bond Policy.

     If the Trustee is not the  Controlling  Party it shall not be  permitted to
take any such  proceedings  against the Company  and/or AMBAC unless it has been
directed  by the  Controlling  Party  to do so and  shall  only be bound to take
proceedings  against the Company at the direction of the Controlling Party if it
has been  indemnified to its  satisfaction by the Controlling  Party (or, if the
Trustee  is the  Controlling  Party,  unless  it  has  been  indemnified  to its
satisfaction by the Bondholders).

                                      -81-


16.  CONTROLLING PARTY

     Subject to (i) the terms of the Trust  Deed,  (ii) AMBAC being at that time
the  Controlling  Party and (iii) AMBAC  giving  notice to the  Trustee  that it
intends to exercise  the Trust  Rights.  AMBAC shall have  exclusive  control to
exercise  the Trust  Rights or to direct the  exercise  of the Trust  Rights (as
applicable) without regard to the interests of any other person, and will not be
a fiduciary or owe any  fiduciary  duties to any person under the Trust Deed and
will be exclusively  authorised to direct and refrain from directing the Trustee
under the Trust Deed in the exercise of the Trust Rights  without  regard to the
interests of any other person.

     For these purposes "Trust Rights" means (i) the right to direct the Trustee
to consent to any amendment, waiver, modification and/or extension of any of the
provisions of the Trust Deed or any document  entered into pursuant to the Trust
Deed and (ii) the right to direct  the  Trustee  with  respect to each and every
right,  power and  discretion  of, or  exercisable  by,  the  Trustee  under any
provisions of the Trust Deed or any document  entered into pursuant to the Trust
Deed.

17.  REPLACEMENT OF BONDS AND COUPONS

     Should any Bond or Coupon be lost, stolen, mutilated,  defaced or destroyed
it may,  subject to all  applicable  laws and stock  exchange  requirements,  be
replaced at the  specified  office of the  Principal  Paying Agent or such other
Paying Agent as may be approved by the Trustee for such purpose) upon payment by
the claimant of the expenses,  taxes and duties incurred in connection therewith
and on such terms as to evidence  and  indemnity  as the Company may  reasonably
require.  Mutilated  or defaced  Bonds or  Coupons  must be  surrendered  before
replacements will be issued.

18.  NOTICES

     All notices to  Bondholders  shall be valid if  published  (i) in a leading
English language national daily newspaper (which is expected to be the Financial
Times) or, if this is not  practicable,  in such leading English  language daily
newspaper  with a circulation  in Europe as the Trustee may approve and (ii) (so
long as the Bonds are listed on the  Luxembourg  Stock Exchange so require) in a
leading newspaper having general circulation in Luxembourg (which is expected to
be the Luxemburger Wort). Such notices shall be deemed to have been given on the
date of such  publication or, if published more than once or on different dates,
on  the  date  of the  first  such  publication  in  both  such  newspapers.  If
publication is not practicable,  notice shall be given in such other manner, and
shall be deemed to have been given on such date, as the Trustee may approve.

     Couponholders  will be  deemed  for all  purposes  to  have  notice  of the
contents  of any  notice  given  to the  Bondholders  in  accordance  with  this
Condition.

19.  MEETINGS OF BONDHOLDERS, MODIFICATION AND WAIVER

     The  Trust  Deed  contains   provisions  for  convening   meetings  of  the
Bondholders  to  consider  any  matter  affecting  their  interests,   including


                                      -82-

modification  by  Extraordinary  Resolution of these Terms and Conditions or the
provisions  of the Trust  Deed.  The quorum at any such  meeting  for passing an
Extraordinary  Resolution shall be one or more persons holding or representing a
clear majority in principal amount of the Bonds for the time being  outstanding,
or at any  adjourned  such  meeting one or more  persons  being or  representing
Bondholders  whatever the principal  amount of the Bonds so held or represented,
except that, at any meeting the business of which includes the  modification  of
certain of these Terms and Conditions and certain of the provisions of the Trust
Deed (including  altering the currency of payment of the Bonds or Coupons),  the
necessary  quorum for passing an  Extraordinary  Resolution  will be one or more
persons holding or representing  not less than  two-thirds,  or at any adjourned
such meeting not less than one-third,  in principal  amount of the Bonds for the
time being  outstanding.  An Extraordinary  Resolution  passed at any meeting of
Bondholders shall be binding on all Bondholders, whether or not they are present
or represented at the meeting, and on all Couponholders.

     Subject as provided in the Trust Deed,  AMBAC is entitled to receive notice
of and to attend meetings of Bondholders but is not entitled to vote.

     Subject  to the  prior  written  consent  of  AMBAC  (if  AMBAC is then the
Controlling  Party),  the Trustee may, without the consent of the Bondholders or
Couponholders, agree (i) to any modification to these Terms and Conditions or to
any of the  provisions  of the Trust Deed or the Bond Policy or to any waiver or
authorisation of any breach or proposed breach by the Company of these Terms and
Conditions or of any of the  provisions of the Trust Deed or determine  that any
event,  condition  or act which would  otherwise  be an Issuer  Event of Default
shall not be so treated  provided that, in the opinion of the Trustee,  so to do
would not be materially prejudicial to the interests of the Bondholders, or (ii)
to any modification to these Terms and Conditions or to any of the provisions of
the Trust Deed or the Bond Policy  which is made to correct a manifest  error or
which is of a formal,  minor or technical nature,  provided that the Company and
AMBAC may, without the consent of the Bondholders or Couponholders, agree to any
modification to Condition 11.

     In  connection  with the  exercise of its trusts,  powers,  authorities  or
discretions   (including,   but  not  limited  to,  any  modification,   waiver,
authorisation or  substitution),  the Trustee shall have regard to the interests
of Bondholders as a class and, in particular, but without limitation,  shall not
have  regard  to the  consequences  of the  exercise  of its  trusts,  powers or
discretions for individual  Bondholders and  Couponholders  resulting from their
being for any purpose domiciled or resident in, or otherwise  connected with, or
subject to the jurisdiction  of, any particular  territory and the trustee snail
not be entitled to require, nor shall the Bondholder or Couponholder be entitled
to claim,  from the Company,  AMBAC or any other person any  indemnification  or
payment in respect of any tax  consequence of any such exercise upon  individual
Bondholders  or  Couponholders,  except to the extent  already  provided  for in
Condition 9 and/or any undertaking given to, or in substitution for, Condition 9
pursuant to the Trust Deed.

     Any  modification to these Terms and Conditions or to any of the provisions
of the Trust  Deed or the Bond  Policy or any  waiver  or  authorisation  of any
breach or proposed breach by the Company of these Terms and Conditions or any of
the  provisions  of the Trust Deed shall be binding on the  Bondholders  and the
Couponholders  and, unless the Trustee agrees otherwise,  any modification shall
be notified by the Company to the Bondholders as soon as practicable  thereafter
in accordance with Condition 18.

                                      -83-


20.  SUBSTITUTION

     The Trustee may,  without the consent of the Bondholders or  Couponholders,
agree with the  Company,  with the  consent  of AMBAC  (such  consent  not to be
unreasonably  withheld  or  delayed)  to the  substitution  of any  wholly-owned
Subsidiary of the Company in place of the Company (or of any previous substitute
under this Condition) as the principal  debtor under the Bonds,  the Coupons and
the Trust Deed,  subject to the Trustee  being of the opinion that the interests
of the Bondholders will not be materially  prejudiced  thereby and certain other
conditions  set out in the Trust Deed being  complied with including the Company
unconditionally  and irrevocably  guaranteeing that Subsidiary's  obligations in
respect of the Bonds and the Coupons).

21.  FURTHER BONDS

          (a) Subject as mentioned below,  power will be reserved to the Company
     to create and issue Further Bonds forming (or so as to form after the first
     payment of interest thereon) a single series with the Bonds provided that:

               (i) AMBAC has consented (in its absolute  discretion) to amend or
          substitute  the Bond  Policy so that the Bond  Policy also covers such
          Further Bonds on the same terms as the Bonds;

               (ii) the Trustee is satisfied  that the rating granted in respect
          of the  Bonds  by S&P  and  Moody's  will  not  thereby  be  adversely
          affected; and

               (iii) such issue shall be constituted by a deed  supplemental  to
          the Trust Deed (in such form as the Trustee may approve).

          (b) The Company  shall not be entitled to exercise the power  reserved
     in this Condition 21 while any default exists in relation to any payment by
     the Company of any amounts due under the Trust Deed.

22.  TRUSTEE

     The Trust Deed  contains  provisions  governing the  responsibility  of the
Trustee  and  providing  for  its  indemnification  in  certain   circumstances,
including  provisions  relieving it from taking proceedings  against the Company
and/or AMBAC unless indemnified to its satisfaction.  The Trustee may not resign
its appointment  unless a successor,  willing to act in such capacity,  has been
appointed  by the  Company  with  the  prior  consent  of  AMBAC  (if  then  the
Controlling  Party) and the Bondholders by  Extraordinary  Resolution,  provided
that the Trustee  shall not be prevented  from  resigning  its  appointment  if,
having given notice in writing to the Company and AMBAC (if then the Controlling

                                      -84-


Party) of its  intention  to so  resign  its  appointment,  a  successor  is not
appointed within the period of three months from the date of such notice.

23.  GOVERNING LAW

     The Trust Deed, the Bonds, the Coupons and the Bond Policy are governed by,
and shall be construed in accordance with, English law.

     meeting  specified in such voting  certificate  or any  adjournment of such
     meeting)  bearing  specified serial numbers were deposited with such Paying
     Agent (or to its order at a bank or other  depositary)  and that such Bonds

     adjournment of it; and

     specified in such block voting  instruction or any  adjournment of it) have
     been  deposited  with such Paying Agent (or to its order at a bank or other
     depositary) and that such Bonds will not be released until the earlier of:

     1)  the  conclusion  of the  meeting  specified  in  such  document  or any
     adjournment of it; and

     attributable  to his Bonds so deposited  should be cast in a particular way

     of it and that all such  instructions  are,  during  the period of 48 hours
     before  the time  fixed for such  meeting  or  adjourned  meeting,  neither
     revocable nor subject to amendment;

                                      -89-


     C. the total number and the serial  numbers of the Bonds so  deposited  are

     instructed  by such Paying  Agent to vote in respect of the Bonds so listed
     in accordance with the instructions  referred to in (C) above as set out in
     such document.

     (iii) "24 HOURS" shall mean a period of 24 hours including all or part of a
     day upon  which  banks are open for  business  in both the place  where the

     Agents have their specified offices  (disregarding for this purpose the day
     upon which such meeting is to be held) and such period shall be extended by
     one period  or, to the extent  necessary,  more  periods of 24 hours  until

     or require a Paying Agent to issue a block voting instruction by depositing
     his Bond with such  Paying  Agent not later  than 48 hours  before the time
     fixed for any meeting.  Voting  certificates and block voting  instructions
     shall be valid until the relevant Bonds are released  pursuant to paragraph
     1 and until then the holder of any such voting  certificate or (as the case
     may be) the proxy named in any such block voting instruction shall, for all
     purposes in connection with any meeting or proposed meeting of Bondholders,
     be deemed to be the holder of the Bonds to which such voting certificate or
     block voting instruction relates and the Paying Agent with which (or to the
     order of which)  such  Bonds have been  deposited  shall be deemed for such
     purposes not to be the holder of those Bonds.

     (3) Each of the  Issuer,  AMBAC and the  Trustee  at any time may,  and the
     Trustee (subject to its being  indemnified to its satisfaction  against all
     costs and  expenses  thereby  occasioned)  upon a  request  in  writing  of
     Bondholders  holding not less than  one-tenth  in  principal  amount of the
     Bonds  for  the  time  being  outstanding  shall,   convene  a  meeting  of
     Bondholders.  Whenever  any such party is about to convene any such meeting
     it shall  forthwith give notice in writing to the other parties of the day,
     time and  place of the  meeting  and of the  nature of the  business  to be
     transacted  at it. Every such meeting  shall be held at such time and place
     as the Trustee may approve.

                                      -90-


     (4) At least 21 days' notice  (exclusive  of the day on which the notice is
     given and of the day on which the meeting is held) specifying the day, time
     and place of meeting shall be given to the Bondholders  (with a copy to the
     Issuer and AMBAC or, where the meeting is convened by the Issuer, AMBAC and
     the Trustee). A copy of the notice shall in all cases be given by the party
     convening the meeting to the other parties. Such notice shall also specify,
     unless in any particular case the Trustee otherwise  agrees,  the nature of
     the  resolutions to be proposed and shall include a statement to the effect
     that Bonds may be deposited  with (or to the order of) any Paying Agent for
     the purpose of obtaining  voting  certificates  or  appointing  proxies not
     later than 48 hours before the time fixed for the meeting.

     (5) A person (who may, but need not, be a Bondholder)  nominated in writing
     by the  Trustee  may take the chair at every  such  meeting  but if no such
     nomination is made or if at any meeting the person  nominated  shall not be
     present  within  15  minutes  after  the time  fixed  for the  meeting  the
     Bondholders  present  shall  choose  one of their  number  to be  chairman,
     failing  which the  Issuer  may  appoint a  chairman.  The  chairman  of an
     adjourned  meeting  need  not be the same  person  as was  chairman  of the
     original meeting.

     (6) At any such meeting any one or more persons  present in person  holding
     Bonds or voting  certificates  and holding or representing in the aggregate
     not less than one-tenth in principal amount of the Bonds for the time being
     outstanding  shall  (except  for the  purpose of  passing an  Extraordinary
     Resolution)  form a quorum for the  transaction of business and no business
     (other than the choosing of a chairman)  shall be transacted at any meeting
     unless the requisite quorum be present at the commencement of business. The
     quorum at any such meeting for passing an  Extraordinary  Resolution  shall
     (subject  as  provided  below)  be one or more  persons  present  in person
     holding Bonds or voting  certificates  and holding or  representing  in the
     aggregate a clear  majority in  principal  amount of the Bonds for the time
     being  outstanding  provided  that at any  meeting  the  business  of which
     includes  any of the matters  specified  in the proviso to paragraph 19 the
     quorum  shall be one or more  persons  present in person  holding  Bonds or
     voting  certificates  and holding or representing in the aggregate not less
     than  two-thirds  in  principal  amount  of the  Bonds  for the time  being
     outstanding.

     (7) If within 15 minutes  from the time fixed for any such meeting a quorum
     is not present the meeting  shall,  if  convened  upon the  requisition  of
     Bondholders,  be  dissolved.  In any other  case it shall  stand  adjourned
     (unless the Issuer,  AMBAC and the Trustee agree that it be dissolved)  for
     such period, not being less than 14 days nor more than 42 days, and to such
     place, as may be decided by the chairman.  At such adjourned meeting one or
     more  persons  present  in  person  holding  Bonds or  voting  certificates
     (whatever the principal  amount of the Bonds so held or represented)  shall
     form a quorum and may pass any resolution and decide upon all matters which
     could  properly  have  been  dealt  with  at the  meeting  from  which  the
     adjournment  took place had a quorum been present at such meeting  provided
     that at any adjourned  meeting at which is to be proposed an  Extraordinary
     Resolution for the purpose of effecting any of the modifications  specified
     in the proviso to  paragraph  19 the quorum shall be one or more persons so
     present holding Bonds or voting  certificates  and holding in the aggregate
     not less than one-third in principal amount of the Bonds for the time being
     outstanding.

                                      -91-


     (8) The  chairman  may with the consent of (and shall if  directed  by) any
     meeting  adjourn such meeting from time to time and from place to place but
     no business shall be transacted at any adjourned  meeting  except  business
     which might  lawfully  have been  transacted  at the meeting from which the
     adjournment took place.

     (9) At least 10 days'  notice of any meeting  adjourned  through  want of a
     quorum  shall be given in the same  manner as for an  original  meeting and
     such notice shall state the quorum required at such adjourned  meeting.  It
     shall  not,  however,  otherwise  be  necessary  to give any  notice  of an
     adjourned meeting.

     (10) Every  question  submitted to a meeting  shall be decided in the first
     instance by a show of hands and in case of  equality of votes the  chairman
     shall both on a show of hands and on a poll have a casting vote in addition
     to the vote or votes  (if any)  which he may have as a  Bondholder  or as a
     holder of a voting certificate.

     (11) At any meeting,  unless a poll is (before or on the declaration of the
     result of the show of hands) demanded by the chairman,  the Issuer,  AMBAC,
     the Trustee or by one or more  persons  holding one or more Bonds or voting
     certificates  and holding or  representing  in the  aggregate not less than
     one-fiftieth  in  principal   amount  of  the  Bonds  for  the  time  being
     outstanding,  a  declaration  by the chairman  that a  resolution  has been
     carried or carried by a  particular  majority or lost or not carried by any
     particular  majority shall be conclusive evidence of the fact without proof
     of the number or proportion  of the votes  recorded in favour of or against
     such resolution.

     (12) If at any  meeting  a poll is so  demanded,  it shall be taken in such
     manner and  (subject  as  provided  below)  either at once or after such an
     adjournment  as the  chairman  directs and the result of such poll shall be
     deemed to be the  resolution  of the meeting at which the poll was demanded
     as at the date of the  taking of the poll.  The demand for a poll shall not
     prevent the continuation of the meeting for the transaction of any business
     other than the question on which the poll has been demanded.

     (13) Any poll  demanded at any meeting on the  election of a chairman or on
     any  question  of  adjournment  shall  be  taken  at  the  meeting  without
     adjournment.

     (14)  The  Issuer,   the  Trustee  and  AMBAC  (through  their   respective
     representatives)  and their  respective  financial  and legal  advisers may
     attend and speak at any meeting of  Bondholders.  No one else may attend at
     any meeting of  Bondholders or join with others in requesting the convening
     of  such  a  meeting  unless  he  is  the  holder  of a  Bond  or a  voting
     certificate.

     (15) At any  meeting  on a show of hands  every  person  who is  present in
     person and who  produces a Bond or voting  certificate  shall have one vote
     and on a poll very person who is so present  shall have one vote in respect
     of each (pound)10,000  principal amount of Bonds so produced or represented
     by the voting certificate.  Without prejudice to the obligations of proxies
     named in any block voting instruction, any person entitled to more than one
     vote  need  not use all his  votes  or cast  all the  votes  to which he is
     entitled in the same way.
                                      -91-


     (16)  The  proxy  named  in any  block  voting  instruction  need  not be a
     Bondholder.

     (17) Each block voting  instruction  shall be  deposited at the  registered
     office  (of the  Issuer,  or at  such  other  place  as the  Trustee  shall
     designate or approve,  not less than 24 hours before the time appointed for
     holding  the meeting or  adjourned  meeting at which the proxy named in the
     block voting  instruction  proposes to vote and in default the block voting
     instruction  shall not be  treated  as valid  unless  the  chairman  of the
     meeting decides otherwise before such meeting or adjourned meeting proceeds
     to  business.  A  notarially  certified  copy of  each  such  block  voting
     instruction and satisfactory proof (if applicable) shall if required by the
     Trustee be produced by the proxy at the  meeting or  adjourned  meeting but
     the Trustee  shall not thereby be obliged to  investigate  or be  concerned
     with the  validity  of, or the  authority  of, the proxy  named in any such
     block voting instruction.

     (18)  Any vote  given  in  accordance  with  the  terms  of a block  voting
     instruction  shall be valid even if the block voting  instruction or any of
     the  Bondholders'  instructions  pursuant to which it was executed has been
     previously  revoked or amended,  provided  that no intimation in writing of
     such  revocation  or amendment  shall have been  received from the relevant
     Paying  Agent by the Issuer or the Trustee at its  registered  office or by
     the  chairman of the meeting in each case not less than 24 hours before the
     time fixed for the meeting or  adjourned  meeting at which the block voting
     instruction is used.

     (19) A meeting of Bondholders shall, subject to the Conditions, in addition
     to the powers given above, but without prejudice to any powers conferred on
     other persons by this Trust Deed, have power  exercisable by  Extraordinary
     Resolution:

     (A) to sanction any  proposal by the Issuer or AMBAC for any  modification,
     abrogation,  variation or compromise  of, or arrangement in respect of, the
     rights of the  Bondholders  and/or  the  Couponholders  against  the Issuer
     (whether such rights shall arise under this Trust Deed or otherwise) or the
     obligations of AMBAC under the Bond Policy;

     (B) to  sanction  the  exchange  or  substitution  for the Bonds of, or the
     conversion  of the Bonds  into,  shares,  bonds,  or other  obligations  or
     securities  of the  Issuer  or any  other  body  corporate  formed or to be
     formed;

     (C) to assent to any  modification  of this  Trust  Deed,  the Bonds or the
     Coupons which shall be proposed by the Issuer or the Trustee;

                                      -93-


     (D) to  authorise  anyone  to  concur  in and do all such  things as may be
     necessary to carry out and give effect to any Extraordinary Resolution;

     (E) to give any  authority,  direction  or sanction  which under this Trust
     Deed or the Bonds is required to be given by Extraordinary Resolution;

     (F) to appoint any persons  (whether  Bondholders or not) as a committee or
     committees to represent the interests of the Bondholders and to confer upon
     such  committee  or  committees   any  powers  or  discretions   which  the
     Bondholders could themselves exercise by Extraordinary Resolution;

     (G) to approve a person  proposed to be  appointed  as a new Trustee and to
     remove any Trustee;

     (H) to  approve  the  substitution  of any  entity  for the  Issuer (or any
     previous  substitute)  as  principal  debtor  under  this Trust Deed or the
     substitution of any person for AMBAC as guarantor under the Bond Policy;

     (I) to discharge or exonerate  the Trustee from any liability in respect of
     any act or omission  for which it may become  responsible  under this Trust
     Deed, the Bonds or the Coupons; and

     (J) to  waive or  authorise  any  breach  by the  Issuer  or AMBAC of their
     respective obligations under this Trust Deed and the Bond Policy;

     provided  that the special  quorum  provisions  contained in the proviso to
     paragraph 6 and,  in the case of an  adjourned  meeting,  in the proviso to
     paragraph 7 shall apply in relation to any Extraordinary Resolution for the
     purpose  of  paragraph  19(B)  or (H) or for  the  purpose  of  making  any
     modification  to the provisions  contained in this Trust Deed, the Bonds or
     the Coupons which would have the effect of:

     1)postponing  the  maturity of the Bonds or the dates on which  interest is
     payable in respect of the Bonds; or

     2)reducing or cancelling  the principal  amount of, any premium  payable on
     redemption of, or interest on the Bonds; or

     3) changing the currency of payment of the Bonds; or

     4)modifying the provisions contained in this Schedule concerning the quorum
     required at any meeting of Bondholders or the majority  required to pass an
     Extraordinary Resolution; or

     5) amending this proviso.

                                      -94-


          (20) An  Extraordinary  Resolution  passed at a meeting of Bondholders
     duly convened and held in accordance  with this Trust Deed shall be binding
     upon all the Bondholders,  whether or not present at such meeting, and upon
     all the Couponholders  and each of the Bondholders and Couponholders  shall
     be  bound  to give  effect  to it  accordingly.  The  passing  of any  such
     resolution  shall be  conclusive  evidence that the  circumstances  of such
     resolution justify the passing of it.

          (21) The  expression  "EXTRAORDINARY  RESOLUTION"  means a  resolution
     passed at a meeting of  Bondholders  duly  convened and held in  accordance
     with  these   provisions  by  a  majority   consisting  of  noc  less  than
     three-quarters of the votes cast.

          (22) Minutes of all  resolutions and proceedings at every such meeting
     shall be made and entered in the books to be from time to time provided for
     that  purpose  by the  Issuer  or the  Trustee  and any  such  minutes,  if
     purporting  to be signed  by the  chairman  of the  meeting  at which  such
     resolutions were passed or proceedings transacted or by the chairman of the
     next succeeding meeting of Bondholders, shall be conclusive evidence of the
     matters  contained  in them and until the  contrary  is proved  every  such
     meeting in respect of the  proceedings  of which  minutes have been so made
     and  signed  shall be deemed to have  been duly  convened  and held and all
     resolutions passed or proceedings transacted at it to have been duly passed
     and transacted.

          (23) Subject to all other provisions  contained in this Trust Deed the
     Trustee may without the consent of the  Bondholders  prescribe such further
     regulations regarding the holding of meetings of Bondholders and attendance
     and  voting at them as the  Trustee  may in its sole  discretion  determine
     including  particularly  (but without  prejudice to the  generality  of the
     foregoing)  such   regulations  and  requirements  as  the  Trustee  thinks
     reasonable:

          (A) so as to satisfy  itself that persons who purport to requisition a
     meeting  in  accordance  with  paragraph  3 or  who  purport  to  make  any
     requisition  to the Trustee in accordance  with this Trust Deed are in fact
     Bondholders; and

          (B) as to the form of voting certificates or block voting instructions
     to be issued  pursuant to paragraph 1 so as to satisfy  itself that persons
     who purport to attend or vote at any meeting of Bondholders are entitled to
     do so in accordance with this Trust Deed.

                                      -95-
