         stitution for lost, stolen, mutilated, defaced or destroyed  Securities
         or Coupons (ii) that the  Principal  Paying Agent  shall in respect of
         the Coupons of each  maturity  retain (in the case of Coupons other
         than  Talons) until the expiry of 10 years from the  Relevant  Date in
         respect of such  Coupons and (in the case of Talons) indefinitely
         either all paid or  exchanged  Coupons  of that  maturity  or a list of
         the serial  numbers of Coupons of that maturity still  remaining unpaid
         or unexchanged  and (iii) that such records and Coupons (if any) shall
         be made available to the Trustee at all reasonable times.

7.       GUARANTEE AND INDEMNITY

(A)      THE Guarantor hereby irrevocably and unconditionally guarantees to the
         Trustee:

         (i)      the due and punctual payment in accordance with the provisions
                  of these presents of the principal of and premium (if any) and
                  interest on the Securities and of any other amounts payable by
                  the Issuer under these presents; and

         (ii)     the due and punctual performance and observance by the Issuer
                  of each of the other provisions of these presents on the
                  Issuer's part to be performed or observed.

(B)      If the Issuer fails for any reason whatsoever punctually to pay any
         such principal, premium, interest or other amount, the Guarantor shall
         cause each and every such payment to be made as if the Guarantor
         instead of the Issuer were expressed to be the primary obligor under
         these presents and not merely as surety (but without affecting the
         nature of the Issuer's obligations) to the intent that the holder of
         the relevant Security, Coupon or Receipt or the Trustee (as the case
         may be) shall receive the same amounts in respect of principal,
         premium, interest or such other amount as would have been receivable
         had such payments been made by the Issuer.

(C)      If any payment received by the Trustee or any Holder or  Couponholder
         under the provisions of these presents shall (whether on the subsequent
         bankruptcy,  insolvency or corporate  reorganisation of the Issuer
         or, without  limitation,  on any other event) be avoided or set aside
         for any reason,  such payment shall not be  considered as  discharging
         or  diminishing  the  liability of the  Guarantor  and this  guarantee
         shall continue to apply as if such payment had at all times  remained
         owing by the Issuer and the Guarantor  shall indemnify the Trustee and
         the Holders  and/or  Couponholders  and/or  Receiptholders (as the case
         may be) in respect  thereof  PROVIDED THAT the  obligations  of the
         Issuer and/or the  Guarantor  under this  sub-clause shall, as regards
         each payment made to the Trustee or any Holder or Couponholder or
         Receiptholder  which is avoided or set aside,  be  contingent upon such
         payment  being  reimbursed  to the Issuer or other  persons entitled
         through the Issuer.

(D)      The  Guarantor  hereby  agrees that its  obligations  under this Clause
         shall be  unconditional  and that the Guarantor  shall be fully  liable
         irrespective of the validity, regularity, legality  or  enforceability
         against  the Issuer of, or of any defence or  counter-claim  whatsoever




         available  to the Issuer in relation to, its  obligations  under these
         presents,  whether or not any action has been taken to enforce the same
         or any judgment  obtained against the Issuer, whether or not any of the
         other provisions of these presents have been modified,  whether or not
         any time,  indulgence,  waiver,  authorisation  or consent has been
         granted to the  Issuer by or on  behalf of the  Holders  or the Coupon-
         holders  or the  Receiptholders  or the  Trustee, whether or not any
         determination  has been made by the  Trustee pursuant  to Clause 19(A),
         whether or not there have been any  dealings or  transactions  between
         the Issuer,  any of the Holders or  Couponholders  or Receiptholders or
         the  Trustee,  whether  or  not  the  Issuer  has  been  dissolved,
         liquidated, merged, consolidated, bankrupted or has changed its status,
         functions,  control or  ownership,  whether or not the Issuer has been
         prevented from making payment by foreign exchange provisions applicable
         at its place of registration  or  incorporation  and  whether  or not
         any  other  circumstances  have  occurred  which  might otherwise  con-
         stitute a legal or equitable  discharge of or defence to a guarantor.
         Accordingly the validity of  this  guarantee  shall  not  be  affected
         by reason of any invalidity, irregularity,  illegality  or unenforce-
         ability  of all or any of the  obligations  of the Issuer under these
         presents  and this  guarantee shall not be  discharged  nor shall the
         liability of the  Guarantor  under these  presents be affected by any
         act,  thing or omission or means  whatever  whereby its liability would
         not have been  discharged if it had been the principal debtor.

(E)      Without prejudice to the provisions of Clause 9(A) the Trustee may
         determine from time to time whether or not it will enforce this
         guarantee which it may do without making any demand of or taking any
         proceedings against the Issuer and may from time to time make any
         arrangement or compromise with the Guarantor in relation to this
         guarantee which the Trustee may consider expedient in the interests of
         the Holders.

(F)      The Guarantor waives diligence, presentment, demand of payment, filing
         of claims with a court in the event of dissolution, liquidation, merger
         or bankruptcy of the Issuer,  any right to require a proceeding  first
         against the Issuer, protest or notice with respect to these presents or
         the indebtedness  evidenced  thereby and all demands  whatsoever and
         covenants that this guarantee shall be a continuing  guarantee,  shall
         extend to the ultimate balance of all sums payable and obligations owed
         by the Issuer under these presents,  shall not be discharged  except by
         complete  performance of the obligations in these presents and is
         additional to, and not instead of, any  security  or other  guarantee
         or  indemnity  at any time  existing in favour of any person, whether
         from the Guarantor or otherwise.

(G)      If any moneys shall become payable by the Guarantor under this
         guarantee the Guarantor shall not, so long as the same remain unpaid,
         without the prior written consent of the Trustee:

         (i)      in respect of any amounts paid by it under this guarantee,
                  exercise any rights of subrogation or contribution or, without
                  limitation. any other right or remedy which may accrue to it
                  in respect of or as a result of any such payment; or

         (ii)     in respect of any other moneys for the time being due to the
                  Guarantor by the Issuer, claim payment thereof or exercise any
                  other right or remedy;

         (including in either case claiming the benefit of any security or right
         of set-off or, on the liquidation of the Issuer, proving in competition
         with the Trustee). If, notwithstanding the foregoing, upon the
         bankruptcy, insolvency or liquidation of the Issuer, any payment or
         distribution of assets of the Issuer of any kind or character, whether
         in cash, property or securities, shall be received by the Guarantor
         before payment in full of all amounts payable under these presents
         shall have been made to the Holders, the Couponholders, the



         Receiptholders and the Trustee, such payment or distribution shall be
         received by the Guarantor on trust to pay the same over immediately to
         the Trustee for application in or towards the payment of all sums due
         and unpaid under these presents in accordance with Clause 10.

(H)      The obligations of the Guarantor under these presents constitute
         direct, unconditional and (subject to the provisions of Condition 3)
         unsecured obligations of the Guarantor and (subject as aforesaid) rank
         and will rank pari passu with all other outstanding unsecured and
         unsubordinated obligations of the Guarantor, present and future, but,
         in the event of insolvency, only to the extent permitted by applicable
         laws relating to creditors' rights.

(I)      As separate,  independent and alternative stipulations,  the Guarantor
         unconditionally and irrevocably agrees (1) that any sum which, although
         expressed  to be  payable  by the  Issuer  under  this  Trust Deed, the
         Securities  or the  Coupons,  is for any reason  (whether or not now
         existing and whether or not now known or becoming  known to the Issuer,
         the Guarantor, the Trustee or any holder or Couponholder) not recover-
         able from the Guarantor on the basis of a guarantee will  nevertheless
         be  recoverable  from it as if it were the sole  principal  debtor and
         will be paid by it to the  Trustee on demand and (2) as a primary
         obligation  to indemnify the Trustee, each Holder and each Couponholder
         against any loss suffered by it as a result of any sum  expressed to be
         payable by the Issuer  under this Trust Deed,  the  Securities  or the
         Coupons not being paid on the date and  otherwise in the manner
         specified in this Trust Deed or any payment obligation of the Issuer
         under  this  Trust  Deed,  the  Securities  or the  Coupons  being  or
         becoming  void,  voidable  or unenforceable  for any reason  (whether
         or not now existing and whether or not now known or becoming known to
         the Trustee,  any Holder or any  Couponholder),  the amount of any such
         loss being the amount expressed to be payable by the Issuer in respect
         of the relevant sum.

8.       ENFORCEMENT

(A)      THE Trustee may at any time, at its discretion and without notice, take
         such proceedings and/or other action as it may think fit against or in
         relation to each of the Issuer and the Guarantor to enforce their
         respective obligations under these presents.

(B)      Proof that as regards any specified Security or Coupon the Issuer or
         the Guarantor (as the case may be) has made default in paying any
         amount due in respect of such Security or Coupon shall (unless the
         contrary be proved) be sufficient evidence that the same default has
         been made as regards all other Securities or Coupons (as the case may
         be) in respect of which the relevant amount is due and payable.

(C)      References in the provisions of any Trust Deed supplemental to this
         Trust Deed corresponding to provisos (ii) and (iii) to Clause 2(B) to
         "the rate aforesaid" shall, in respect of any Securities bearing
         interest at a floating or variable rate, in the event of such
         Securities having become due and repayable, with effect from the expiry
         of the interest period during which such Securities become due and
         repayable, be construed as references to a rate of interest calculated
         mutatis mutandis in accordance with the Conditions except that no
         notices need be published in respect thereof.

9.       PROCEEDINGS, ACTION AND INDEMNIFICATION

(A)      THE Trustee shall not be bound to take any proceedings mentioned in
         Clause 8(A) or any other action in relation to these presents unless
         respectively directed or requested to do so (i) by an Extraordinary
         Resolution or (ii) in writing by the holders of at least one-quarter in




         principal amount of the Securities then outstanding and in either case
         then only if it shall be indemnified to its satisfaction against all
         Liabilities to which it may thereby render itself liable or which it
         may incur by so doing.

(B)      Only the Trustee may enforce the provisions of these presents. No
         Holder or Couponholder shall be entitled to proceed directly against
         the Issuer or the Guarantor to enforce the performance of any of the
         provisions of these presents unless the Trustee having become bound as
         aforesaid to take proceedings fails to do so within a reasonable period
         and such failure is continuing.

10.      APPLICATION OF MONEYS

         ALL moneys received by the Trustee under these presents shall, unless
         and to the extent attributable in the opinion of the Trustee to a
         particular series of the Securities, be apportioned pari passu and
         rateably between each series of the Securities, and all moneys received
         by the Trustee under these presents to the extent attributable in the
         opinion of the Trustee to a particular series of the Securities or
         which are apportioned to such series as aforesaid (including any moneys
         which represent principal, premium or interest in respect of Securities
         or Coupons which have become void under Condition 10) shall be held by
         the Trustee upon trust to apply them (subject to Clause 12):

         FIRST in payment or satisfaction of all amounts then due and unpaid
         under Clauses 15 and/or 16(J) to the Trustee and/or any Appointee;

         SECONDLY in or towards payment pari passu and rateably of all
         principal, premium (if any) and interest then due and unpaid in respect
         of the Securities of that series;

         THIRDLY in or towards payment pari passu and rateably of all principal,
         premium (if any) and interest then due and unpaid in respect of the
         Securities of each other series; and

         FOURTHLY in payment of the balance (if any) to the Issuer or the
         Guarantor, as the case may be, (without prejudice to, or liability in
         respect of, any question as to how such payment to the Issuer shall be
         dealt with as between the Issuer, the Guarantor and any other person).

         Without prejudice to this Clause 10, if the Trustee holds any moneys
         which represent principal, premium (if any) and interest in respect of
         the Securities which have become void or in respect of which claims
         have been prescribed under Condition 10, the Trustee will hold such
         moneys on the above trusts.

11.      NOTICE OF PAYMENTS

         THE Trustee shall give notice to the relevant Holders in accordance
         with Condition 15 of the day fixed for any payment to them under Clause
         10. Such payment may be made in accordance with Condition 6 and any
         payment so made shall be a good discharge to the Trustee.

12.      INVESTMENT BY TRUSTEE

(A)      IF the  amount of the moneys at any time available for the  payment  of
         principal,  premium  (if any) and interest in respect of the Securities
         under  Clause 10 shall be less than 10 per cent.  of the  principal
         amount of the Securities  then  outstanding  the Trustee may at its
         discretion  invest such moneys in some or one of the  investments




         authorised  below.  The Trustee at its discretion may vary such invest-
         ments and may accumulate such investments and the resulting income
         until the  accumulations,  together with any other funds for the time
         being under the control of the Trustee and  available for such purpose,
         amount to at least 10 per cent. of the principal amount of the
         Securities then outstanding and then such accumulations and funds shall
         be applied under Clause 10.

(B)      Any moneys  which under the trusts of these presents ought to or may be
         invested  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 by  placing  the
         same 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 think fit. If such bank or  financial  institution  is the  Trustee
         or a  Subsidiary,  holding or  associated company  of the  Trustee  it
         need only  account  for an amount of  interest  equal to the  largest
         amount of interest  payable by it on such a deposit to an  independent
         customer.  The Trustee may at any time vary any such investments for or
         into other  investments  or convert any moneys so deposited into any
         other currency and shall not be responsible  for any loss resulting
         from any such  investments or deposits,  whether due to depreciation in
         value, fluctuations in exchange rates or otherwise.

13.      PARTIAL PAYMENTS

         UPON any payment under Clause 10 (other than payment in full against
         surrender of a Security or Coupon) the Security or Coupon in respect of
         which such payment is made shall be produced to the Trustee or the
         Paying Agent by or through whom such payment is made and the Trustee
         shall or shall cause such Paying Agent to enface thereon a memorandum
         of the amount and the date of payment but the Trustee may in any
         particular case or generally in relation to Registered Securities
         dispense with such production and enfacement upon such indemnity being
         given as it shall think sufficient.

14. COVENANTS BY THE ISSUER AND THE GUARANTOR

         SO long as any of the Securities remains outstanding (or, in the case
         of paragraphs (viii), (ix), (xiii) to (xvi) inclusive and (xviii), so
         long as any of the Securities or Coupons remains liable to
         prescription) each of the Issuer and the Guarantor severally covenants
         with the Trustee that it shall:

         (i)      at all times carry on and conduct its affairs and procure its
                  Subsidiaries (if any) to carry on and conduct their respective
                  affairs in a proper and efficient manner;

         (ii)     give or procure to be given to the Trustee such opinions,
                  certificates, information and evidence as it shall properly
                  require and in such form as it shall properly require
                  (including without limitation the procurement by the Issuer
                  and/or the Guarantor of all such certificates called for by
                  the Trustee pursuant to Clause 16(C)) for the purpose of the
                  proper discharge or exercise of the duties, trusts, powers,
                  authorities and discretions vested in it under these presents
                  or by operation of law;

         (iii)    cause to be prepared and certified by its Auditors in respect
                  of each financial accounting period accounts in such form as
                  will comply with all relevant legal and accounting
                  requirements and all applicable requirements for the time
                  being of The Stock Exchange;

         (iv)     at all times keep and procure its Subsidiaries (if any) to
                  keep proper books of account and following the occurrence of
                  an Event of Default or a Potential Event of Default or if the
                  Trustee has grounds to believe that an Event of Default or a




                  Potential Event of Default has occurred or is likely to occur
                  allow and procure its Subsidiaries to allow the Trustee and
                  any person appointed by the Trustee to whom the Issuer, the
                  Guarantor or the relevant Subsidiary (as the case may be)
                  shall have no reasonable objection free access to such books
                  of account at all reasonable times during normal business
                  hours;

         (v)      send to the Trustee (in addition to any copies to which it may
                  be entitled as a holder of any securities of the Issuer or the
                  Guarantor) two copies in English of every balance sheet,
                  profit and loss account, report, circular and notice of
                  general meeting and every other document issued or sent to its
                  shareholders in their capacity as such together with any of
                  the foregoing, and every document issued or sent to holders of
                  securities other than its shareholders (including the Holders)
                  in their capacity as such as soon as reasonably practicable
                  after the issue or publication thereof;

         (vi)     forthwith give notice in writing to the Trustee of the coming
                  in to existence of any Security Interest which would require
                  any security to be given to any series of the Securities
                  pursuant to Condition 3 or of the occurrence of any Event of
                  Default or any Potential Event of Default or any Restructuring
                  Event

         (vii)    give to the Trustee (a) within  seven days after demand by the
                  Trustee therefor  and (b)  (without the necessity for any such
                  demand) promptly after the publication of its audited accounts
                  (if such audited  accounts are prepared and published) in
                  respect of each financial period commencing with the financial
                  period  ending 31st  March, 1998 (or such later date as may be
                  the end of the first financial period in respect of which such
                  accounts are  required to be prepared)  and in any event not
                  later  than 180 days after the end of each such  financial
                  period a certificate signed by two Directors of the Issuer and
                  two Directors  of the  Guarantor  to the effect  that as at a
                  date not more than seven days before  delivering such certifi-
                  cate (the "relevant date") there did not exist and had not
                  existed  since the  relevant date of the  previous certificate
                  (or in the case of the first such certificate the date hereof)
                  any Event of Default or any Potential  Event of Default or any
                  Restructuring  Event (or if such  exists or existed specifying
                  the same) and that  during the period from and  including  the
                  relevant date of the last such certificate  or in the case of
                  the first such  certificate  the date hereof) to and including
                  the relevant  date of such  certificate each of the Issuer and
                  the Guarantor has complied with all its  obligations contained
                  in these presents or (if such is not the case) specifying the

         holder of any  Coupon as the  absolute  owner of such  Security  or
         Coupon,  as the case may be,  for all  purposes (whether  or not such
         Security  or Coupon  shall be overdue  and  notwithstanding  any notice
         of  ownership thereof,  any notice of loss or theft thereof or any
         writing  thereon),  and the Issuer,  the Guarantor,  the Trustee,  the



         Paying  Agents,  the Registrar  and the Transfer  Agents shall not be

         effective  to satisfy and  discharge  the  liability  for the moneys
         payable in respect of such  Security or Coupon, as the case may be.

                  New Company in form and manner  satisfactory  to the Trustee,
                  agreeing to be bound by the provisions of these presents with
                  any  consequential  amendments  which the Trustee may deem
                  appropriate as fully as if the New  Company  had been named in
                  these  presents  as the  principal  debtor in place of the
                  Issuer (or of the previous  substitute  under this Clause) and
                  provided  further that (other than in the case of a substitu-
                  tion  of the  Guarantor)  the  Guarantor  unconditionally  and
                  irrevocably guarantees all amounts  payable under these
                  presents save where YEG has transferred the PES Licence to the
                  New Company.

                  (i)      the Issuer, the Guarantor and the New Company shall
                           comply with such other requirements as the Trustee
                           may direct in the interests of the Holders;

                  (ii)     without prejudice to the rights of reliance of the
                           Trustee under the immediately following paragraph
                           (iii), the Trustee is satisfied that the relevant
                           transaction is not materially prejudicial to the
                           interests of the Holders; and

                  (iii)    if two Directors of the New Company (or other
                           officers acceptable to the Trustee) shall certify
                           that the New Company is solvent at the time at which
                           the relevant transaction is proposed to be effected
                           (which certificate the Trustee may rely upon
                           absolutely) the Trustee shall not be under any duty
                           to have regard to the financial condition, profits or
                           prospects of the New Company or to compare the same
                           with those of the Issuer or the previous substitute
                           under this Clause as applicable.

         thereof in a form  previously  approved  by the Trustee  to the Holders
         in the manner provided in Condition 15. Upon the execution of such
         documents and  compliance  with such  requirements,  the New  Company
         shall be deemed to be named in these  presents as the  principal debtor

         (a)      any Liability incurred by any of them arising from the

                  between those used for the purposes of calculating the amount
                  due under a judgment or order in respect thereof and those

                  for the purposes of any  bankruptcy, insolvency or liquidation
                  of the Issuer or the Guarantor and (ii) the final date for
                  ascertaining  the amount of claims in such  bankruptcy,
                  insolvency  or  liquidation.  The  amount of such  deficiency
                  shall be deemed not to be reduced by any  variation  in rates
                  of exchange occurring between the said final date and the date
                  of any distribution of assets in connection with any such
                  bankruptcy,  insolvency or liquidation.

         The above indemnities shall constitute obligations of the Issuer and
         the Guarantor separate and independent from their obligations under the
         other provisions of these presents and shall apply irrespective of any
         indulgence granted by the Trustee or the Holders or the Couponholders
         from time to time and shall continue in full force and effect
         notwithstanding the judgment or filing of any proof or proofs in any
         bankruptcy, insolvency or liquidation of the Issuer or the Guarantor
         for a liquidated sum or sums in respect of amounts due under these
         presents (other than this Clause). Any such deficiency as aforesaid
         shall be deemed to constitute a loss suffered by the Holders and
         Couponholders and no proof or evidence of any actual loss shall be
         required by the Issuer or the Guarantor or their liquidator or
         liquidators.

23.      NEW TRUSTEE

(A)      THE power to appoint a new  trustee of these  presents  shall be vested
         in the Issuer but no person shall be appointed who shall not previously
         have been approved by an Extraordinary Resolution.  One or more persons
         may hold office as trustee or trustees of these  presents but such
         trustee or trustees  shall be or include a Trust Corporation.  Whenever
         there shall be more than two  trustees of these  presents the majority
         of such trustees  shall be  competent  to execute and exercise all the
         duties,  powers,  trusts,  authorities  and discretions  vested in the
         Trustee by these presents  provided that a Trust  Corporation shall be
         included in such majority.  Any  appointment  of a new trustee of these
         presents shall as soon as practicable  thereafter be notified by the
         Issuer to the Principal Paying Agent, the Registrar, the Transfer
         Agents and the Holders.

         SEPARATE AND CO-TRUSTEES

(B)      Notwithstanding the provisions of sub-clause (A) above, the Trustee
         may, upon giving prior notice to the Issuer and the Guarantor (but
         without the consent of the Issuer, the Guarantor, the Holders or the
         Couponholders), appoint any person established or resident in any
         jurisdiction (whether a Trust Corporation or not) to act either as a
         separate trustee or as a co-trustee jointly with the Trustee:


         (i)      if the Trustee considers such appointment to be in the
                  interests of the Holders;

         (ii)     for the purposes of conforming to any legal requirements,
                  restrictions or conditions in any jurisdiction in which any
                  particular act or acts is or are to be performed; or

         (iii)    for the purposes of obtaining a judgment in any jurisdiction
                  or the enforcement in any jurisdiction of either a judgment
                  already obtained or any of the provisions of these presents
                  against the Issuer and/or the Guarantor.

         Each of the Issuer and the Guarantor irrevocably appoints the Trustee
         to be its attorney in its name and on its behalf to execute any such
         instrument of appointment. Such a person shall (subject always to the
         provisions of these presents) have such trusts, powers, authorities and
         discretions (not exceeding those conferred on the Trustee by these
         presents) and such duties and obligations as shall be conferred or
         imposed by the instrument of appointment. The Trustee shall have power
         in like manner to remove any such person. Such reasonable remuneration
         as the Trustee may pay to any such person, together with any
         attributable Liabilities incurred by it in performing its function as
         such separate trustee or co-trustee, shall for the purposes of these
         presents be treated as Liabilities incurred by the Trustee.

24. TRUSTEE'S RETIREMENT AND REMOVAL

         A trustee of these presents may retire at any time on giving not less
         than three months' prior written notice to the Issuer and the Guarantor
         without giving any reason and without being responsible for any
         Liabilities incurred by reason of such retirement. The Holders may by
         Extraordinary Resolution remove any trustee or trustees for the time
         being of these presents. The Issuer and the Guarantor undertake that in
         the event of the only trustee of these presents which is a Trust
         Corporation giving notice under this Clause or being removed by
         Extraordinary Resolution they will use their best endeavours to procure
         that a new trustee of these presents being a Trust Corporation is
         appointed as soon as reasonably practicable thereafter. The retirement
         or removal of any such trustee shall not become effective until a
         successor trustee being a Trust Corporation is appointed and if, in
         such circumstances no such appointment has become effective within two
         months of such notice of retirement or Extraordinary Resolution, the
         Trustee shall (with the prior written consent of the Issuer and the
         Guarantor, such consent not be unreasonably withheld) be entitled to
         appoint a trust corporation as Trustee and shall notify the Issuer and
         the Guarantor of such appointment.

25.      TRUSTEE'S POWERS TO BE ADDITIONAL

         THE powers conferred upon the Trustee by these presents shall be in
         addition to any powers which may from time to time be vested in the
         Trustee by the general law or as a holder of any of the Securities or
         Coupons.

26.      NOTICES

27. GOVERNING LAW

         THESE presents are governed by, and shall be construed in accordance
with, English law.



28.      SUBMISSION TO JURISDICTION

(A)      THE Issuer  irrevocably  agrees for the benefit of the Trustee,  the
         Holders and the  Couponholders that the courts of England are to have
         jurisdiction  to settle any disputes  which may arise out of or in
         connection with these presents and that  accordingly  any suit, action
         or  proceedings  arising out of or in connection with these presents
         (together  referred to as  "Proceedings") may be brought in the courts
         of England.  The Issuer  irrevocably  and unconditionally  waives and
         agrees not to raise any objection which it may have now or subsequently
         to the laying of the venue of any  Proceedings in the courts of England
         and any claim that any Proceedings have been brought in an inconvenient
         forum and further  irrevocably  and  unconditionally agrees that a
         judgment in any  Proceedings  brought in the courts of England shall be
         conclusive and binding upon the Issuer and may be enforced  in the
         courts of any other jurisdiction.  Nothing in this Clause  shall limit
         any right to take  Proceedings against the Issuer in any other court of
         competent  jurisdiction,  nor shall the taking of  Proceedings  in one
         or more  jurisdictions  preclude  the taking of  Proceedings  in any
         other jurisdiction, whether concurrently or not.

(B)      The Issuer irrevocably and unconditionally appoints the Guarantor
         (which appointment the Guarantor hereby accepts) at its registered

         service of process on its behalf in England in respect of any
         Proceedings. The Issuer:

         (i)      agrees to procure that, so long as any of the Securities
                  remains liable to prescription, there shall be in force an
                  appointment of such a person approved by the Trustee with an
                  office in England with authority to accept service as
                  aforesaid;

         (ii)     agrees that failure by any such person to give notice of such
                  service of process to the Issuer shall not impair the validity
                  of such service or of any judgment based thereon;

         (iii)    consents to the service of process in respect of any
                  Proceedings by the airmailing of copies, postage prepaid, to
                  the Issuer in accordance with Clause 26; and

         (iv)     agrees that nothing in these presents shall affect the right
                  to serve process in any other manner permitted by law.

         present for the transaction of any particular  business,  then, subject
         and without  prejudice to the  transaction of the business (if any) for
         which a quorum is present,  the Chairman may either  (with the approval
         of the  Trustee)  dissolve  such meeting or adjourn the same for such
         period, being not less than 14 clear days (but without any maximum
         number of clear  days),  and to such place as may be appointed by the
         Chairman either at or subsequent to such adjourned meeting and approved
         by the Trustee, and the  provisions of this sentence shall apply to all
         further  adjourned  such  meetings.  At any adjourned meeting  one or
         more  persons  present  holding  Securities  or voting certificates or
         being  proxies  or representatives  (whatever  the principal  amount of
         the  Securities  so held or  represented  by them) shall (subject as
         provided  below)  form a quorum and shall  (subject as  provided below)
         have power to pass any Extraordinary  Resolution or other  resolution
         and to decide upon all matters which could properly have been dealt
         with at the  meeting  from which the  adjournment  took place had the
         requisite  quorum been present PROVIDED THAT at any  adjourned meeting
         the quorum for the  transaction  of business  comprising  any of the
         matters  specified  in the  proviso  to  paragraph  5 above  shall  be
         one or more  persons  present holding Securities or voting certificates
         or being proxies or representatives and holding or  representing in the
         aggregate not less than one-third of the principal amount of the
         Securities for the time being outstanding.

7.       Notice of any adjourned meeting at which an Extraordinary Resolution is
         to be submitted shall be given in the same manner as notice of an
         original meeting but as if 10 were substituted for 21 in paragraph 3
         above and such notice shall state the relevant quorum. Subject as
         aforesaid it shall not be necessary to give any notice of an adjourned
         meeting.

8.       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) to which he may be
         entitled as a Holder or as a holder of a voting certificate or as a
         proxy or as a representative.

9.       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, the
         Guarantor, the Trustee or any person present holding a Security or a
         voting certificate or being a proxy or representative (whatever the
         principal amount of the Securities so held or represented by him) a
         declaration by the Chairman that a resolution has been carried or
         carried by a particular majority or lost or not carried by a 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.

10.      Subject to paragraph 12 below, if at any such meeting a poll is so
         demanded it shall be taken in such manner and subject as hereinafter
         provided either at once or after an adjournment as the Chairman directs
         and the result of such pol1 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 continuance of
         the meeting for the transaction of any business other than the motion
         on which the poll has been demanded.

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




12.      Any poll demanded at any such meeting on the election of a Chairman or
         on any question of adjournment shall be taken at the meeting without
         adjournment.

13.      The Trustee and its lawyers and  financial advisers and any  director,
         officer or employee of a corporation being a trustee  of these presents
         and any  director  or officer  of the  Issuer or the  Guarantor and its
         lawyers and its accountants and financial advisers and any other person
         authorised so to do by the Trustee may attend and speak at any meeting.
         Save as  aforesaid,  but  without  prejudice  to the  proviso to the
         definition  of  "outstanding"  in Clause 1, no person shall be entitled
         to attend  and speak nor shall any person be entitled to vote at any
         meeting of the Holders or join with others in  requesting the convening
         of such a meeting or to exercise the rights conferred on the Holders by
         Conditions  11 and 12 unless he either produces the Bearer Security or
         Bearer Securities of which he is the holder or a voting  certificate or
         is a proxy or a  representative  or is the holder of a Registered
         Security or Registered Securities.  No person shall be entitled to vote
         at any meeting in respect of Securities  held by, for the benefit of,
         or on behalf of, the Issuer, the Guarantor, any other Subsidiary of the
         Guarantor, any holding company of the Guarantor or any other Subsidiary
         of any such holding  company.  Nothing herein shall prevent any of the
         proxies named in any block voting  instruction  or form of proxy or any
         representative  from being a director,  officer or representative of or
         otherwise connected with the Issuer or the Guarantor.

14.      Subject as provided in paragraph 13 hereof at any meeting:

         (A)      on a show of hands every person who is present in person and
                  produces a Bearer Security or voting certificate or is a
                  holder of Registered Securities or is a proxy or
                  representative shall have one vote; and

         (B)      on a poll every person who is so present shall have one vote
                  in respect of each (pound)1 or such other amount as the
                  Trustee may in its absolute discretion stipulate (or, in the
                  case of meetings of holders of Securities denominated in
                  another currency, such amount in such other currency as the
                  Trustee in its absolute discretion may stipulate) in principal
                  amount of the Securities so produced or represented by the
                  voting certificate so produced or in respect of which he is a
                  proxy or representative or in respect of which he is the
                  holder.

         Without prejudice to the obligations of the proxies named in any block
         voting instruction or form of proxy 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.

I5.      In respect of Registered Securities, in the case of joint holders the
         vote or the senior who tenders a vote whether in person or by proxy
         shall be accepted to the exclusion of the votes of the other joint
         holders and for this purpose seniority shall be determined by the order
         in which the names stand in the register of Holders as the Holders
         thereof.

16.      The proxies named in any block voting instruction or form of proxy and
         representatives need not be Holders.

17.      Each block voting instruction together (if so requested by the Trustee)
         with proof  satisfactory  to the Trustee  of its due  execution  on
         behalf of the  relevant  Paying  Agent and each form of proxy shall be
         deposited  by the  relevant  Paying  Agent  or (as the  case may be) by
         the  Registrar  at such  place as the Trustee shall  approve not less
         than 24 hours before the time  appointed for holding the meeting or
         adjourned meeting at which the proxies  named in the block voting



         instruction  or form of proxy propose to vote and in default the block
         voting  instruction  or form of proxy 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 block  voting  instruction  and form of proxy
         shall be  deposited  with the  Trustee before the  commencement of 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 proxies  named in any such block voting instruction or
         form of proxy.

18.      Any vote given in  accordance with the terms of a block voting instruc-
         tion  or form of proxy shall be valid notwithstanding  the previous
         revocation or amendment of the block voting instruction or form of
         proxy or of any of the Holders'  instructions  pursuant to which it was
         executed  provided  that no intimation in writing of such  revocation
         or amendment  shall have been received from the relevant Paying Agent
         or in the case of a Registered  Security from the holder thereof by the
         Issuer at its  registered  office (or such other place as may have been
         required or approved by the Trustee for the  purpose) by the time being
         24 hours and 48 hours respectively before the time appointed for
         holding the  meeting or  adjourned  meeting at which the block voting
         instruction or form of proxy is to be used.

19.      A meeting of the Holders shall in addition to the powers hereinbefore
         given have the following powers exercisable only by Extraordinary
         Resolution (subject to the provisions relating to quorum contained in
         paragraphs 5 and 6 above) namely:

         (A)      Power to sanction any compromise or arrangement proposed to be
                  made between the Issuer, the Guarantor, the Trustee, any

         (B)      Power to sanction any abrogation, modification, compromise or
                  arrangement in respect of the rights of the Trustee, any

                  Guarantor against any other or others of them or against any

                  presents or otherwise.

         (C)      Power to assent to any modification of the provisions of these
                  presents which shall be proposed by the Issuer, the Guarantor,

         (D)      Power to give any authority or sanction which under the

         (E)      Power to appoint any persons (whether Holders or not) as a
                  committee or committees to represent the interests of the

                  Appointee from all liability in respect of any act or omission
                  for which the Trustee and/or such Appointee may have become
                  responsible under these presents.

         (H)      Power to authorise the Trustee and/or any Appointee to concur
                  in and execute and do all such deeds, instruments, acts and

                  shares, stock, bonds, notes, debentures, debenture stock

                  consideration of cash, or partly for or into or in

20.      Any resolution passed at a meeting of the Holders duly convened and
         held in accordance with these presents shall be binding upon all the
         Holders whether present or not present at such meeting and whether or
         not voting and upon all Couponholders and each of them shall be bound
         to give effect thereto accordingly and the passing of any such

         resolution duly considered by the Holders shall be published in
         accordance with Condition 15 by the Issuer within 14 days of such
         result being known PROVIDED THAT the non-publication of such notice
         shall not invalidate such result.

21.      The expression "Extraordinary Resolution" when used in these presents
         means a resolution passed at a meeting of the Holders duly convened and
         held in accordance with these presents by a majority consisting of not
         than three-fourths of the persons voting thereat upon a show of hands
         or if a poll is duly demanded by a majority consisting of not less than
         three-fourths of the votes cast on such poll.

22.      Minutes of all resolutions and proceedings at every meeting of the
         Holders shall be made and entered in books to be from time  to time
         provided for that purpose by the Issuer and any such Minutes as
         aforesaid if purporting to be signed by the Chairman of the meeting at
         which such resolutions were passed or proceedings transacted shall be
         conclusive evidence of the matters therein contained and until the
         contrary is proved every such meeting in respect of the proceedings of
         which Minutes have been made shall be deemed to have been duly held
         and convened and all resolutions passed or proceedings transacted
         thereat to have been duly passed or transacted.

23.      (A)      If and whenever the Issuer shall have issued and have
                  outstanding Securities of more than one series the foregoing
                  provisions of this Schedule shall have effect, subject to the
                  following modifications:

                  (i)      a resolution which in the opinion of the Trustee
                           affects the Securities of only one series shall be
                           deemed to have been duly passed if passed at a
                           separate meeting of the holders of the Securities of
                           that series;

                  (ii)     a resolution which in the opinion of the Trustee
                           affects the Securities of more than one series but
                           does not give rise to a conflict of interest between
                           the holders of Securities of any of the series so
                           affected shall be deemed to have been duly passed if
                           passed at a single meeting of the holders of the
                           Securities of all the series so affected;

                  (iii)    a resolution which in the opinion of the Trustee
                           affects the Securities of more than one series and
                           gives or may give rise to a conflict of interest
                           between the holders of the Securities of one series
                           or group of series so affected and the holders of the
                           Securities of another series or group of series so
                           affected shall be deemed to have been duly passed
                           only if passed at separate meetings of the holders of
                           the Securities of each series or group of series so
                           affected; and


                  (iv)     to all such meetings all the preceding provisions of
                           this Schedule shall mutatis mutandis apply as though
                           references therein to Securities, Holders and holders
                           were references to the Securities of the series or
                           group of series in question or to the holders of such
                           Securities, as the case may be.

         (B)      If the Issuer shall have issued and have outstanding
                  Securities  which are not  denominated in pounds  sterling, in
                  the case of any meeting of holders of Securities of more than
                  one currency the principal  amount  of such  Securities  shall
                  (i) for the  purposes of paragraph  2 above  be the equivalent
                  in  pounds  sterling  at the  spot  rate  of a bank  nominated
                  by the  Trustee  for the conversion of the relevant  currency
                  or currencies  into pounds sterling on the seventh dealing day
                  prior to the day on which the  requisition  in  writing is
                  received by the Issuer and (ii) for the purposes of paragraphs
                  5, 6 and 14 above  (whether in respect of the meeting or any
                  adjourned  such meeting  or any poll  resulting therefrom) be
                  the  equivalent  at such  spot  rate on the  seventh dealing
                  day  prior to the day of such meeting.  In such circumstances,
                  on any poll  each  person present shall have one vote for each
                  (pound)1 (or such other pound  sterling  amount as the Trustee
                  may in its absolute  discretion stipulate) in principal amount
                  of the  Securities  (converted  as above) which he holds or
                  represents.

24.      Subject to all other provisions of these presents the Trustee may
         without the consent of the Issuer, the Guarantor, the Holders or the
         Couponholders prescribe such further regulations regarding the
         requisitioning and/or the holding of meetings of Holders and attendance
         and voting thereat as the Trustee may in its sole discretion think fit.
