     (g)  where the Facility is an FX Line, a notice given at least two Business
          Days in advance specifying the proposed date for each foreign exchange
          or option  transaction,  it being clearly understood that we shall not
          be obliged to enter into any  particular FXC at any time if we, in our
          sole  discretion,  determine  not to do so and shall not be obliged to
          give any reason therefor;

     (h)  Where the Facility  permits  drawings in currencies  other than Pounds
          Sterling or exchanges  between  currencies  (whether or not  including
          Pounds Sterling), a notice given at least two Business Days in advance
          specifying the proposed date for each transaction;

     (i)  such legal  opinions as we shall  consider  are  necessary  to satisfy
          ourselves  that you have  capacity to accept the Facility and that the
          Security  Documents are legally


                                       3

<PAGE>



          valid and binding  obligations  of you duly  enforceable in accordance
          with these terms;

     (j)  such other  documentation  as we shall reasonably  consider  necessary
          including Account Opening Documentation;

     (k)  Payment of any facility fees as specified in the Facility Letter.

3.   Undertakings
     You  undertake  to us that until the  termination  date or until all monies
     which may become due by you to us pursuant to the Facility are paid:

     (a)  your liabilities  pursuant to this facility will rank at least equally
          and rateably  (pari passu) in point of priority and security  with all
          your other liabilities (both actual and contingent) except:

          (i)  liabilities  which  are  subject  to liens or  rights  of set off
               arising in the normal  course of your  business and the amount of
               which will not in our opinion,  prejudice your ability to perform
               you obligations hereunder; and,

          (ii) liabilities  which are preferred  solely by Jersey Law and not by
               reason of any security interest;

          and you will not create or permit to exist over any of your assets any
          security  interest other than is permitted  under (i) above unless the
          benefit of the  security  interest  is, upon its  creation or arising,
          extended  equally and rateably to our satisfaction to your liabilities
          under the Facility  Letter and so that, in default of such  extension,
          the person  entitled to the security  interest shall (if he had notice
          of this  undertaking)  hold the security interest pro tanto upon trust
          for us;

     (b)  where you are a corporate  body,  you will carry on and  conduct  your
          business and affairs in a proper and efficient manner;

     (c)  you shall not effect any of the following without our prior consent in
          writing:

            (i)   sell or otherwise  dispose of any material part of your assets
                  or, where you are a corporate  body, any material part of your
                  business;

            (ii)  enter into any partnership or joint venture agreement;

            (iii) where you are  a  corporate  body,  enter  into any  contract
                  outside your normal course of business;

            (iv)  where you are a corporate  body,  enter into any  transaction,
                  arrangement  or  agreement  with or for the  benefit of any of
                  your directors;

            (v)   create or issue any debenture,  mortgage,  charge or any other
                  security.


                                       4

<PAGE>



     (d)  where applicable,  you will notify us forthwith if you become aware of
          the  occurrence  of an Event of  Default  or any event  which with the
          giving  of a notice  and/or  the  lapse of time  and/or  the  relevant
          determination would constitute such an Event of Default.

     (e)  where security is being taken by the charging of immovable property:

          (i)  you shall maintain  insurance on the Property in accordance  with
               good commercial practice, against such risks and for such amounts
               and with such  insurance  company as may be acceptable to us and,
               without  prejudice to the  generality of the foregoing and unless
               otherwise  agreed in writing,  such insurance shall include cover
               for  damage  arising  from  fire,   explosion,   storm,  tempest,
               earthquake,  impact,  subsidence,  aircraft and articles  dropped
               therefrom,  malicious  damage,  bursting and overflowing of pipes
               and tanks, riot and civil commotion,  flooding, lightning and oil
               leakage,  and you shall  ensure that our interest in the Property
               is noted thereon; and

          (ii) you shall not without our prior written consent (which may in our
               absolute  discretion  be  refused)  alter  the  structure  of the
               Property  or enter into any  contract  for the  refurbishment  or
               renovation  of the  Property or in any way deal with the Property
               including,  but  without  prejudice  to  the  generality  of  the
               foregoing, the granting of leases or tenancies of the Property.

4.   Further Representations and Warranties
     By acceptance of the Facility you represent and warrant to us that:

     (a)  you have the capacity to enter into,  exercise your rights and perform
          and comply  with the  obligations  under the  Facility  Letter and the
          Security Documents;

     (b)  the  obligations  expressed as being assumed by you under the Facility
          Letter and the Security  Documents  constitute  your valid,  legal and
          binding  obligations  enforceable against you in accordance with their
          respective terms;

     (c)  neither the execution and delivery of the form of acceptance  endorsed
          on the  Facility  Letter  or the  Security  Documents  by you  nor the
          performance or observance of any of your obligations under this Letter
          or the Security  Documents will conflict with, or result in any breach
          of, any law, statute,  regulation,  indenture,  mortgage,  trust deed,
          agreement  or other  instrument,  arrangement,  obligation  or duty by
          which  you are bound or cause any  limitation  on any of your  powers,
          howsoever  imposed,  or on your  right or  ability  to  exercise  such
          powers, to be exceeded;

     (d)  no Event of Default has occurred and remains unremedied;

     (e)  in the event that you are acting as a trustee,  all  necessary  action
          has been taken to appoint you as trustee of the trusts declared by the
          Trust  Deed and you have the power and  authority  as such  trustee to
          accept  the  Facility  and to give the  security  contemplated  by the
          Security Documents;


                                       5

<PAGE>



     (f)  you are not in default under any law, statute, regulation,  indenture,
          mortgage,  trust deed,  agreement  or other  instrument,  arrangement,
          obligation or duty by which you are bound;

     (g)  there exists no mortgage,  charge,  pledge, lien, encumbrance or other
          security  interest  whatsoever  over  the  whole  or any  part of your
          assets, present or future; and

     (h)  no litigation,  administrative or arbitration  proceeding before or of
          any court,  government  authority or  arbitrator  is presently  taking
          place,  pending  or  threatened  against  you or  against  any of your
          assets.

          These representations and warranties shall be deemed to be repeated on
          the  date  of  the  first  and  (where   applicable)   any  subsequent
          draw-downs. For the avoidance of doubt, each utilisation of an FX Line
          shall be deemed to be a separate draw-down.

5.   Valuation of Property and Surveyor's Reports
     Where security is being taken by the charging of immovable property:

     (a)  At any time during the  continuance  of the Facility we shall have the
          right at your  expense to appoint an  independent  valuer to value the
          Property the valuation  being made on such basis as we in our absolute
          discretion shall determine.

     (b)  If at any time in our opinion the net realisable value of the Security
          would not exceed the amount  required to  discharge  all amounts  owed
          under the Facility by the applicable Margin, we may, without prejudice
          to any  rights  to  demand  repayment  of the  whole of the  Facility,
          require you, on such terms as we shall determine, to:

          (i)  reduce the amounts  owing under the Facility by such amount as we
               shall specify; or

          (ii) provide  such  further  security  acceptable  to us,  as shall in
               either case restore the Margin.

     (c)  In addition we shall have the right at your  expense to appoint at any
          time during the  continuance  of the Facility an  independent  firm of
          chartered surveyors to report to us on the structural condition of the
          Property or on such other matter as we in our absolute  discretion see
          fit.

6. Margin
We shall from time to time determine the Margin  required by us and in the event
that the net realisable value of the Security does not in our opinion provide us
with the required Margin upon our request you shall, without prejudice to any of
our rights to demand repayment restore the Margin either by reducing the amounts
of your liability to us or providing us with further security acceptable to us.


                                       6

7.   Authorisation
     In the event of any sum  becoming due by you to us pursuant to the Facility
     you hereby  authorise us to debit any of your  accounts with the amount due
     or, in our absolute  discretion,  to sell all or any securities held in any
     capacity  by us for you in order to  realise  the amount due and you hereby
     agree that we shall be under no  obligation to give any prior notice of any
     action taken  pursuant to the  authority  hereby  conferred  and you hereby
     indemnify us against all actions,  proceedings,  losses, costs, damages and
     other  demands  which you may  suffer or incur by reason of or arising as a
     result of our taking any action hereby authorised.

8.   Costs and Expenses
     You will forthwith pay to us on demand all reasonable  expenses,  including
     legal fees,  incurred by us in  connection  with your  application  for the
     Facility, the granting of the Facility, the preparation and/or the approval
     of the  Security  Documents  and any  approvals  thereunder  or  variations
     thereof and their preservation or enforcement or attempted  preservation or
     enforcement.

9.   Interest
     In the case of Pounds Sterling  liabilities,  interest will accrue on a 365
     day year basis.  In any other case,  interest will accrue on a 360 day year
     basis.

10.  Taxes

     All  payments to be made by you  hereunder  shall be made free and clear of
     any  deduction  or  withholding;  if you are  required  by law to make  any
     deduction  or  withholding  on  account of tax or  otherwise  from any such
     payment, the sum due from you in respect of such payment shall be increased
     to the extent  necessary to ensure that, after the making of such deduction
     or  withholding,  we receive a net sum equal to the sum which we would have
     received had no deduction or withholding been made.

11.  Increased Costs 
     If by reason of:

     (a)  any change in law or in its interpretation of administration; and/or

     (b)  compliance with any request from or requirement of any central bank or
          other fiscal, monetary or other authority;

     the cost to us or funding or  maintaining  the  Facility is increased or we
     become  liable  to make any  payment  (not  being a  payment  of tax on our
     overall net income) or any increased  payment on or calculated by reference
     to the  amount of the  Facility,  you shall from time to time on our demand
     promptly pay to us amounts sufficient to indemnify us against,  as the case
     may be, such increased cost or such liability. If we intend to make a claim
     pursuant to this paragraph for  indemnification  against an increased cost,
     we shall  notify you of the event by reason of which we are  entitled to do
     so. Any  determination by us of the amount of any such increased cost shall
     be conclusive and binding on you for all purposes.


                                       7

12.  Rights Cumulative, Waiver
     Our rights under the Facility  Letter are  cumulative,  may be exercised as
     often as we consider  appropriate  and are in addition to our rights  under
     the general law. Our rights  (whether  arising under the Facility Letter or
     under the  general  law)  shall not be  capable  of being  waived or varied
     otherwise  than  by an  express  waiver  or  variation  in  writing  and in
     particular  any failure to exercise or any delay in exercising  any of such
     rights shall not operate as a waiver or variation of that or any other such
     right;  any  defective  of partial  exercise  of any such  right  shall not
     preclude  any other or further  exercise of that or any other such  rights;
     and no act or course of conduct or negotiation on our part shall in any way
     preclude us from  exercising  any such right or  constitute a suspension or
     any variation of such right.

13.  Events of Default
     If any of the following events occur:

     (a)  you fail to pay any  amount due under the  Facility  Letter on the due
          date or on demand, if so payable;

     (b)  you fail to observe  or perform  any  obligations  under the  Facility
          Letter or under the Security Documents as the case may be or under any
          undertaking or arrangement entered into in connection therewith;

     (c)  any   representation,   warranty  or  statement   which  is  made  (or
          acknowledged to have been made) by you in connection with the Facility
          proves to be incorrect in any material respect;

     (d)  any  indebtedness  of you or the Guarantor for borrowed  money becomes
          due and payable prior to its specified maturity,  you or the Guarantor
          are in breach or default under any agreement or document evidencing or
          regulating such indebtedness, you or the Guarantor fail to pay any sum
          due to be paid by you under the  Facility or the  Guarantor  under the
          Guarantee,  you or the  Guarantor  are unable or fail to admit your or
          the Guarantor's inability to pay your or the Guarantor's debts as they
          fall  due,  or  commit  any act or  omission  which is  indicative  of
          insolvency  or make a  general  assignment  for the  benefit  of, or a
          composition with, your or the Guarantor's creditors;

     (e)  an  encumbrancer  takes  possession or a trustee,  receiver or similar
          officer is  appointed  of any of your or the  Guarantor's  assets or a
          distress or any form of execution is levied or forced upon any of your
          or the Guarantor's assets;

     (f)  it becomes  unlawful  for you or the  Guarantor  or us to perform  the
          obligations   under  the  Facility  Letter  or  any  of  the  Security
          Documents;

     (g)  any circumstances  arise which give reasonable  grounds in our opinion
          for the  belief  that you may not (or may be unable to)  perform  your
          obligations under the Facility Letter;



                                       8

<PAGE>



     (h)  you or the Guarantor become or are declared bankrupt as defined in the
          Interpretation  (Jersey)  Law 1954 or  commit  any act  indicative  of
          bankruptcy;

     (i)  any Security Documents shall cease to be enforceable by us;

     (j)  in the case of FX Lines only,  at any time we  determine  that the net
          cumulative book losses  attributable to open FXCs,  including  Matched
          FXCs, exceeds 40% of the lendable value of the Security; or

     (k)  in the case of FX Lines only,  at any time within two Business Days of
          the date of maturity of any open FXC which is unmatched, we are of the
          opinion that you have  insufficient  funds in accounts on which we are
          entitled  to draw for the  purpose of meeting  liabilities  under that
          FXC;

     then we may at any  time  thereafter  by  notice  to you  declare  that the
     Facility,  together with accrued interest and all amounts payable hereunder
     are immediately due and payable and the Facility shall thereupon  terminate
     (or, in the case of an FX Line,  we may close out or match,  in  accordance
     with the Close-Out Formula, sufficient FXCs to restore the margin).

14.  Close-Out Formula
     Closing out of FXCs other than option shall be  conducted in the  following
     manner (the "Close-Out Formula"):

14.1 (a)  each  balance  of  currency  (other  than  the Base  Currency)  with a
          Settlement  Date on or after the  Close-Out  Date shall be  notionally
          converted  into the Base Currency at the  appropriate  market rate (as
          conclusively  determined  by us) at which on the  Close-Out  Date,  we
          could enter into a contract in the foreign exchange market to buy that
          other  currency in exchange for the Base  Currency for delivery on the
          appropriate Settlement Date;

     (b)  in respect of each  Settlement  Date, the balance of the Base Currency
          account for such Settlement  Date shall be consolidated  with the Base
          Currency sum  calculated  in  accordance  with  paragraph (a) above to
          determine  the net amount to be paid or  received  on such  Settlement
          Date;

     (c)  each Base Currency amount  calculated in accordance with paragraph (b)
          above  will be  notionally  discounted  so as to  calculate  the  Base
          Currency sum which,  when aggregated with the amount of interest which
          could be  earned on that sum if it were  placed  on a deposit  for the
          period  from  the  Close-Out  Date  to  the  Settlement  Date  at  the
          appropriate  Eurodollar  rate (to be  conclusively  determined by us),
          assuming (in the case of Pounds  Sterling) a year with 365 days or (in
          the case of any other currency) a year with 360 days,  would equal the
          relevant Base Currency amount;

     (d)  on the basis that an amount  outstanding  to your  credit is an amount
          owed by us to you and an amount outstanding to your debit is an amount
          owing from you to us,


                                       9

<PAGE>



          the aggregate  amount of all the Base Currency  amounts  calculated in
          accordance with paragraph (a), (b) and (c) above as owed by you to us,
          will be  deducted  from the  aggregate  amount  of all  Base  Currency
          amounts so calculated as owing to you; and

     (e)  the  amounts  determined  shall  be  payable  by us if that  deduction
          produces a positive  figure  and by you if that  deduction  produces a
          negative figure.

14.2 In the case of FXCs consisting of options,  closing-out  shall be conducted
     by  purchasing  or writing from or with you FXCs on such terms as we in our
     absolute discretion think fit (the "Option Close-Out Formula"),  but with a
     view to  there  arising  Matched  FXCs,  in which  case you  shall be bound
     accordingly.

14.3 We shall not be liable  to you for any loss or other  damage  which you may
     suffer  as a  result  of our  exercise  of any of  our  rights  under  this
     agreement in respect to Closing-Out or entering into any other transactions
     with a view to protecting our position in accordance with this clause.

14.4 Following  close  out,  all  obligations  of us to you,  or of you to us in
     respect  of  FXCs  shall  be  automatically   and  immediately   satisfied,
     discharged  and replaced by an  obligation  upon you or us, as the case may
     be, to pay an amount determined in accordance with the Close-Out Formula or
     the Option Close-Out Formula.

15.  Maturing FXCs
     On the maturity of FXCs, all entries will be passed over the Account unless
     otherwise agreed by us.

16.  Netting Off

16.1 Immediately  upon  any FXC  other  than a put or  call  option  written  or
     purchased by you or for your account being entered into  resulting in there
     being Matched FXCs:

     (a)  the amount of each currency  bought under a Matched FXC will be netted
          against the aggregate amount of that currency sold under all FXCs with
          which it is matched and vice versa, and

     (b)  all obligations  under each such FXC will be  automatically  satisfied
          and  discharged and replaced by an obligation to pay the net aggregate
          amount  resulting from such netting of each currency on the Settlement
          Date to you or us as the case may be.

16.2 Immediately  upon  any  put or  call  option  being  written  or  purchased
     resulting  in there being  Matched  FXCs,  the amount of each  currency the
     subject of the purchased call option which is a Matched FXC shall be netted
     against the aggregate  amount of that  currency to be delivered  under call
     options  written,  or put options  purchased with which it is matched,  and
     vice  versa,  and the amount of each  currency  the subject of a put option
     written which is a Matched FXC will be netted against the aggregate  amount
     of that currency the subject of all call options purchased and vice-versa.


                                       10

<PAGE>



16.3 In the case of put  options or call  options  which are Matched  FXCs,  the
     liability  under such  Matched  FXCs  shall be  mutually  extinguished  and
     neither of us shall  thereafter  be  entitled  to call on the other for the
     exercise of such options.

16.4 FXCs  shall be  capable  of being  matched  in part,  in which case the FXC
     covering the larger  amount of  underlying  currency  shall be deemed to be
     divided  into two  parts:  the part  that is  matched  and the part that is
     unmatched. Upon the one part becoming matched, the balance shall be treated
     as a new FXC.

17.  Set off
     At all times,  whether before or after the right to close-out FXCs (if any)
     has arisen in  addition  to any other of our rights we shall be entitled to
     apply any sum due from us to you on any account  whatsoever and in whatever
     currency in or towards satisfaction of any sum due to us from you.

18.  Withdrawals
     Any  withdrawal  made pursuant to the Facility  shall be made on a Business
     Day and shall be deemed to constitute a repeat of the warranties set out in
     this Appendix.

19.  Notices
     Any notices or communications under the Facility Letter shall be in writing
     and shall be delivered  personally  or sent by post,  telex or cable to the

                 WHEREAS  the  pledgor  has placed  the  deposit  with  CITIBANK

                 the depository (hereinafter the "securities",  which term shall
                 include all rights and dividends  accruing to such  securities)

                 indebtedness  of any  pledgor/borrower  vis-a-vis  the pledgee.
                 Except if expressly  otherwise  provided  for,  all  securities
                 shall be considered as being fungible.

                 WHEREAS  the  facility  shall at all  times be  secured  by the
                 aggregate   of  the  pledge  on  deposit   and  the  pledge  on
                 securities.

                 WHEREAS the facility may never exceed the loanable value of the
                 assets pledged by the pledgor to the pledgee.

                 WHEREAS the loanable  value of the  securities  and the deposit
                 shall be calculated  and monitored on a permanent  basis by the
                 depositary  as  agent of the  pledgee  in  accordance  with the
                 margin  table  set  out  in  appendix  hereto.  The  depositary
                 reserves the right to make any necessary  changes to the margin
                 table  based  on  the  quality,  liquidity,  marketability  and

                 depositary  (as  applicable  from  time  to  time)  is  at  the
                 permanent disposal of the pledgor/borrower by the depositary.

                 WHEREAS the depositary  shall be the agent of and represent the
                 pledgee  in any acts and  deeds to be  undertaken  or signed in
                 order to give effect to this pledge  agreement.  The depositary
                 shall for instance be empowered to accept this pledge agreement
                 on behalf of the pledgee, to monitor the loanable value, and to
                 request and accept an additional  pledge of securities and/or a
                 pledge of deposit, pursuant to clause 3.2. of this agreement.

                 WHEREAS for all acts and deeds under this pledge agreement, the
                 depositary  (even if acting in his own name) shall be deemed to
                 act as an agent for the pledgee.

NOW AND THEREFORE THE PARTIES HAVE AGREED AS FOLLOWS:

1. PLEDGE ON DEPOSIT

1.1 The pledgor hereby pledges the deposit in favour of the pledgee.

1.2 The depositary is empowered,  upon instruction of the pledgee, to convert at
any time all or part of the deposit into  certificates  of deposit,  held by the
depositary  in safe custody for the pledgor and pledged in favour of the pledgee
pursuant to clause 2.1 hereafter.

1.3 The pledge shall remain in full force and effect until the  pledgor/borrower
has fulfilled all its obligations  under the facility,  in principal,  interest,
commissions,  fees and other charges including the repayment of all judicial and
extra  judicial  costs  incurred  for the  recovery of any amounts due under the
facility.

1.4 The pledgor  hereby  agrees that this  pledge  agreement  be notified to the
depositary at the pledgor's  exclusive costs and expenses in the appropriate way
under Luxembourg law.

1.5 If the  pledgor/borrower  does not fulfill,  on due date,  any commitment or
obligation  towards  the  pledgee  under the  facility,  or shall not have fully
complied  within  eight  days  from the date of a  summons  containing  a formal
request to satisfy the claims of the  pledgee  under the  facility,  the pledgee
shall be authorized to demand  payment,  transfer and delivery of the deposit in
view to  satisfy  its  secured  claims,  in  accordance  with  applicable  legal
provisions.

2. PLEDGE ON SECURITIES

2.1 The pledgor hereby pledges all securities to the pledgee, who accepts.

2.2 The  depositary  holds the  securities in surety in a special pledge account
and  guarantee  for the due and  punctual  payment of all amounts of  principal,
interest,  commissions,  fees and other  charges  including the repayment of all
judicial and extra  judicial  costs incurred for the recovery of any amounts due
under the  facility or of any debt which is now due and payable or may become in
the future due and payable to the pledgee by the  pledgor/borrower,  as and when
the same shall become due and payable.

2.3 The pledgor hereby represents and warrants:

2.3.1 that the securities are free and clear of any claims, mortgages,  pledges,
liens or other encumbrances of any nature whatsoever,  and that the pledgor will
not sell and will keep the  securities  fee and clear of any claims,  mortgages,
pledges, liens or other encumbrances of any nature whatsoever;

2.3.2 that the present  agreement  is not  contrary to any legal or  contractual
obligation  imposed  upon the  pledgor,  and that it creates  valid and  binding
obligations upon him.

2.4 If and when a formal  notice of repayment to the borrower and the pledgor by
the pledgee or the  depository,  by way of a  registered  letter,  has  remained
unsatisfied  for eight days, the pledgee may instruct the depositary to sell the
securities,  in accordance  with  applicable  legal  provisions,  and assign the
proceeds  by  privilege  to  the  reimbursement  of  the  said  debt  due by the
pledgor/borrower  to the  pledgee  upon  transfer  of the sales  proceeds by the
depository  to the  pledgee.

3. GENERAL

3.1 If the outstanding  amount of the facility exceeds or threatens to exceed at
any time, the loanable value of the deposit and the securities pledged in favour
of the pledgee,  the pledgor  undertakes,  within five days of first demand,  to
pledge,  mortgage,  transfer  and  assign to the  pledgee,  and  deliver  to the
depository, further securities and/or a further deposit into the account, to the
extent  necessary  for the facility no longer to exceed or to threaten to exceed
the loanable value of the deposit and the securities.

3.2 In the event of failure to comply with the obligation undertaken pursuant to
clause 3.1 above, the pledgor herewith  unconditionally and irrevocably empowers
the pledgee to take all  appropriate  measures,  and in particular to effect all
transactions  in order to reduce the  outstanding  liabilities  to the  loanable
value of the deposit and the  securities,  or to render due and payable any sums
due to the pledgee by the pledgor, and to enforce this pledge agreement pursuant
to clause 1.5 and 2.4 above.

3.3 The pledgee shall not be limited in its  discretion to enforce the pledge on
deposit or the pledge on securities,  whether  simultaneously  or alternatively,
whether in full or in part.  The  enforcement,  in full or in part,  of the mere
pledge on deposit,  or of the pledge on securities,  as the case may be, does to
constitute  a waiver by the  pledgee  to any of his  rights  under the pledge on
securities and/or under the pledge on deposit, as the case may be.

3.4 For the duration of this pledge agreement,  the pledgor irrevocably empowers
the depositary to give the pledgee from time to time full disclosure  concerning
the details of the securities and the deposit. All communications by the pledgee
to either the borrower or the pledgor shall be deemed to be provided to both.

3.5 The obligations of the pledgor hereunder shall not be affected or discharged
in case of the occurrence of any of the following events:

     -    any time,  indulgence,  waiver  or  consent  at any time  given to the
          pledgor/borrower or any other person;

     -    any  amendment  to any  of  the  facility  documents  or to any  other
          security or any guarantee or indemnity for the facility;

     -    the enforcement or absence of enforcement of claims for or the release
          of the facility or any other security,  guarantee or indemnity for the
          facility;

     -    the   dissolution,   amalgamation,   bankruptcy,   reconstruction   or
          re-organization of the pledgor/borrower or any other person.

3.6 The pledgee is explicitly  authorized to  communicate  openly and assign its
rights  hereunder  to all other  Citicorp/Citibank  entities  which are granting
credit to the  pledgor/borrower or which may be in possession of assets securing
such  credit or which are a party with or on behalf of the  pledgor/borrower  in
foreign exchange or securities transactions.

3.7 Generally,  the pledgor shall bear all costs,  expenses,  taxes,  duties and
similar  charges which shall be incurred to the pledgee by virtue of this pledge
agreement  now or in the future,  including any costs of  notification,  even to
foreign counties,  and including all court and legal expenses arising out of the



<PAGE>



enforcement  of  the  pledgee's  rights,  and  the  pledgor  hereby  irrevocably
authorizes the pledgee and empowers the depository to debit such amount from the
account.

3.8 This pledge  agreement shall in all respects be governed by and construed in
accordance with the laws of the Grand Dutchy of Luxembourg.

3.9 This  pledge  agreement  is  subject  the  depository's  general  terms  and
conditions,  which the pledgor declares having read and accepted, and which form
an integral part of this pledge  agreement  inasfar as applicable and consistent
with this pledge agreement.

proceedings  arising  out of or in  connection  with this  pledge  agreement  is
submitted  to the  jurisdiction  of the  Courts of  Luxembourg,  Grand  Duchy of

despositary.

          (i)  liabilities  which  are  subject  to liens or  rights  of set off
               arising in the normal  course of your  business and the amount of

          extended  equally and rateably to our satisfaction to your liabilities
          under the Facility  Letter and so that, in default of such  extension,

          the  occurrence  of an Event of  Default  or any event  which with the
          giving  of a notice  and/or  the  lapse of time  and/or  the  relevant
          determination would constitute such an Event of Default.

     (e)  where security is being taken by the charging of immovable property:

          (i)  you shall maintain  insurance on the Property in accordance  with
               good commercial practice, against such risks and for such amounts

               is noted thereon; and

               Property  or enter into any  contract  for the  refurbishment  or
               renovation  of the  Property or in any way deal with the Property

          Security Documents;

     (b)  the  obligations  expressed as being assumed by you under the Facility
          Letter and the Security  Documents  constitute  your valid,  legal and
          binding  obligations  enforceable against you in accordance with their
          respective terms;

     (c)  neither the execution and delivery of the form of acceptance  endorsed
          on the  Facility  Letter  or the  Security  Documents  by you  nor the
          performance or observance of any of your obligations under this Letter
          or the Security  Documents will conflict with, or result in any breach
          of, any law, statute,  regulation,  indenture,  mortgage,  trust deed,
          agreement  or other  instrument,  arrangement,  obligation  or duty by
          which  you are bound or cause any  limitation  on any of your  powers,

          powers, to be exceeded;

<PAGE>



     (f)  you are not in default under any law, statute, regulation,  indenture,
          mortgage,  trust deed,  agreement  or other  instrument,  arrangement,
          obligation or duty by which you are bound;

     (g)  there exists no mortgage,  charge,  pledge, lien, encumbrance or other
          security  interest  whatsoever  over  the  whole  or any  part of your
          assets, present or future; and

     (h)  no litigation,  administrative or arbitration  proceeding before or of
          any court,  government  authority or  arbitrator  is presently  taking
          place,  pending  or  threatened  against  you or  against  any of your
          assets.

     These  representations and warranties shall be deemed to be repeated on the
     date of the first and (where applicable) any subsequent draw-downs. For the
     avoidance of doubt,  each utilisation of an FX Line shall be deemed to be a

     (a)  At any time during the  continuance  of the Facility we shall have the
          right at your  expense to appoint an  independent  valuer to value the
          Property the valuation  being made on such basis as we in our absolute
          discretion shall determine.

     (b)  If at any time in our opinion the net realisable value of the Security
          would not exceed the amount  required to  discharge  all amounts  owed
          under the Facility by the applicable Margin, we may, without prejudice
          to any  rights  to  demand  repayment  of the  whole of the  Facility,
          require you, on such terms as we shall determine, to:

          (i)  reduce the amounts  owing under the Facility by such amount as we
               shall specify; or

          (ii) provide  such  further  security  acceptable  to us,  as shall in
               either case restore the Margin.

     (c)  In addition we shall have the right at your  expense to appoint at any
          time during the  continuance  of the Facility an  independent  firm of
          chartered surveyors to report to us on the structural condition of the
          Property or on such other matter as we in our absolute  discretion see
          fit.

6.   Margin
     We shall from time to time  determine the Margin  required by us and in the
     event that the net realisable value of the Security does not in our opinion
     provide us with the  required  Margin upon our  request you shall,  without
     prejudice  to any of our  rights to demand  repayment  restore  the  Margin
     either by reducing the amounts of your liability to us or providing us with
     further security acceptable to us.

     of the  Security  Documents  and any  approvals  thereunder  or  variations
     thereof and their preservation or enforcement or attempted  preservation or
     enforcement.

9.   Interest
     In the case of Pounds Sterling  liabilities,  interest will accrue on a 365
     day year basis.  In any other case,  interest will accrue on a 360 day year
     basis.

10.  Taxes
     All  payments to be made by you  hereunder  shall be made free and clear of
     any  deduction  or  withholding;  if you are  required  by law to make  any
     deduction  or  withholding  on  account of tax or  otherwise  from any such
     payment, the sum due from you in respect of such payment shall be increased
     to the extent  necessary to ensure that, after the making of such deduction
     or  withholding,  we receive a net sum equal to the sum which we would have
     received had no deduction or withholding been made.

11.  Increased Costs
     If by reason of:

     (a)  any change in law or in its interpretation of administration; and/or

     (b)  compliance with any request from or requirement of any central bank or
          other fiscal, monetary or other authority;

     the cost to us or funding or  maintaining  the  Facility is increased or we
     become  liable  to make any  payment  (not  being a  payment  of tax on our
     overall net income) or any increased  payment on or calculated by reference
     to the  amount of the  Facility,  you shall from time to time on our demand
     promptly pay to us amounts sufficient to indemnify us against,  as the case
     may be, such increased cost or such liability. If we intend to make a claim
     pursuant to this paragraph for  indemnification  against an increased cost,
     we shall  notify you of the event by reason of which we are  entitled to do
     so. Any  determination by us of the amount of any such increased cost shall
     be conclusive and binding on you for all purposes.

12.  Rights Cumulative, Waiver
     Our rights under the Facility  Letter are  cumulative,  may be exercised as
     often as we consider  appropriate  and are in addition to our rights  under
     the general law. Our rights  (whether  arising under the Facility Letter or
     under the  general  law)  shall not be  capable  of being  waived or varied
     otherwise  than  by an  express  waiver  or  variation  in  writing  and in
     particular  any failure to exercise or any delay in exercising  any of such
     rights shall not operate as a waiver or variation of that or any other such
     right;  any  defective  of partial  exercise  of any such  right  shall not
     preclude  any other or further  exercise of that or any other such  rights;
     and no act or course of conduct or negotiation on our part shall in any way
     preclude us from  exercising  any such right or  constitute a suspension or
     any variation of such right.

13.  Events of Default
     If any of the following events occur:

     (a)  you fail to pay any  amount due under the  Facility  Letter on the due
          date or on demand, if so payable;

     (b)  you fail to observe  or perform  any  obligations  under the  Facility
          Letter or under the Security Documents as the case may be or under any
          undertaking or arrangement entered into in connection therewith;

     (c)  any   representation,   warranty  or  statement   which  is  made  (or
          acknowledged to have been made) by you in connection with the Facility
          proves to be incorrect in any material respect;

     (d)  any  indebtedness  of you or the Guarantor for borrowed  money becomes
          due and payable prior to its specified maturity,  you or the Guarantor
          are in breach or default under any agreement or document evidencing or
          regulating such indebtedness, you or the Guarantor fail to pay any sum
          due to be paid by you under the  Facility or the  Guarantor  under the
          Guarantee,  you or the  Guarantor  are unable or fail to admit your or
          the Guarantor's inability to pay your or the Guarantor's debts as they
          fall  due,  or  commit  any act or  omission  which is  indicative  of
          insolvency  or make a  general  assignment  for the  benefit  of, or a
          composition with, your or the Guarantor's creditors;

     (e)  an  encumbrancer  takes  possession or a trustee,  receiver or similar
          officer is  appointed  of any of your or the  Guarantor's  assets or a
          distress or any form of execution is levied or forced upon any of your
          or the Guarantor's assets;

     (f)  it becomes  unlawful  for you or the  Guarantor  or us to perform  the
          obligations   under  the  Facility  Letter  or  any  of  the  Security
          Documents;

     (g)  any circumstances  arise which give reasonable  grounds in our opinion
          for the  belief  that you may not (or may be unable to)  perform  your
          obligations under the Facility Letter;


                                       8

<PAGE>



     (h)  you or the Guarantor become or are declared bankrupt as defined in the
          Interpretation  (Jersey)  Law 1954 or  commit  any act  indicative  of
          bankruptcy;

     (i)  any Security Documents shall cease to be enforceable by us;

     (j)  in the case of FX Lines only,  at any time we  determine  that the net
          cumulative book losses  attributable to open FXCs,  including  Matched
          FXCs, exceeds 40% of the lendable value of the Security; or

     (k)  in the case of FX Lines only,  at any time within two Business Days of
          the date of maturity of any open FXC which is unmatched, we are of the
          opinion that you have  insufficient  funds in accounts on which we are
          entitled  to draw for the  purpose of meeting  liabilities  under that
          FXC;

     then we may at any  time  thereafter  by  notice  to you  declare  that the
     Facility,  together with accrued interest and all amounts payable hereunder
     are immediately due and payable and the Facility shall thereupon  terminate
     (or, in the case of an FX Line,  we may close out or match,  in  accordance
     with the Close-Out Formula, sufficient FXCs to restore the margin).

14.  Close-Out Formula
     Closing out of FXCs other than option shall be  conducted in the  following
     manner (the "Close-Out Formula"):

14.1 (a)  each  balance  of  currency  (other  than  the Base  Currency)  with a
          Settlement  Date on or after the  Close-Out  Date shall be  notionally
          converted  into the Base Currency at the  appropriate  market rate (as
          conclusively  determined  by us) at which on the  Close-Out  Date,  we
          could enter into a contract in the foreign exchange market to buy that
          other  currency in exchange for the Base  Currency for delivery on the
          appropriate Settlement Date;

     (b)  in respect of each  Settlement  Date, the balance of the Base Currency
          account for such Settlement  Date shall be consolidated  with the Base
          Currency sum  calculated  in  accordance  with  paragraph (a) above to
          determine  the net amount to be paid or  received  on such  Settlement
          Date;

     (c)  each Base Currency amount  calculated in accordance with paragraph (b)
          above  will be  notionally  discounted  so as to  calculate  the  Base
          Currency sum which,  when aggregated with the amount of interest which
          could be  earned on that sum if it were  placed  on a deposit  for the
          period  from  the  Close-Out  Date  to  the  Settlement  Date  at  the
          appropriate  Eurodollar  rate (to be  conclusively  determined by us),
          assuming (in the case of Pounds  Sterling) a year with 365 days or (in
          the case of any other currency) a year with 360 days,  would equal the
          relevant Base Currency amount;

     (d)  on the basis that an amount  outstanding  to your  credit is an amount
          owed by us to you and an amount outstanding to your debit is an amount
          owing from you to us,


                                       9

<PAGE>



          the aggregate  amount of all the Base Currency  amounts  calculated in
          accordance with paragraph (a), (b) and (c) above as owed by you to us,
          will be  deducted  from the  aggregate  amount  of all  Base  Currency
          amounts so calculated as owing to you; and

     (e)  the  amounts  determined  shall  be  payable  by us if that  deduction
          produces a positive  figure  and by you if that  deduction  produces a
          negative figure.

14.2 In the case of FXCs consisting of options,  closing-out  shall be conducted
     by  purchasing  or writing from or with you FXCs on such terms as we in our
     absolute discretion think fit (the "Option Close-Out Formula"),  but with a
     view to  there  arising  Matched  FXCs,  in which  case you  shall be bound
     accordingly.

14.3 We shall not be liable  to you for any loss or other  damage  which you may
     suffer  as a  result  of our  exercise  of any of  our  rights  under  this
     agreement in respect to Closing-Out or entering into any other transactions
     with a view to protecting our position in accordance with this clause.

14.4 Following  close  out,  all  obligations  of us to you,  or of you to us in
     respect  of  FXCs  shall  be  automatically   and  immediately   satisfied,
     discharged  and replaced by an  obligation  upon you or us, as the case may
     be, to pay an amount determined in accordance with the Close-Out Formula or
     the Option Close-Out Formula.

15.  Maturing FXCs
     On the maturity of FXCs, all entries will be passed over the Account unless
     otherwise agreed by us.

16.  Netting Off

16.1 Immediately  upon  any FXC  other  than a put or  call  option  written  or
     purchased by you or for your account being entered into  resulting in there
     being Matched FXCs:

     (a)  the amount of each currency  bought under a Matched FXC will be netted
          against the aggregate amount of that currency sold under all FXCs with
          which it is matched and vice versa, and

     (b)  all obligations  under each such FXC will be  automatically  satisfied
          and  discharged and replaced by an obligation to pay the net aggregate
          amount  resulting from such netting of each currency on the Settlement
          Date to you or us as the case may be.

16.2 Immediately  upon  any  put or  call  option  being  written  or  purchased
     resulting  in there being  Matched  FXCs,  the amount of each  currency the
     subject of the purchased call option which is a Matched FXC shall be netted
     against the aggregate  amount of that  currency to be delivered  under call
     options  written,  or put options  purchased with which it is matched,  and
     vice  versa,  and the amount of each  currency  the subject of a put option
     written which is a Matched FXC will be netted against the aggregate  amount
     of that currency the subject of all call options purchased and vice-versa.


                                       10

<PAGE>



16.3 In the case of put  options or call  options  which are Matched  FXCs,  the
     liability  under such  Matched  FXCs  shall be  mutually  extinguished  and
     neither of us shall  thereafter  be  entitled  to call on the other for the
     exercise of such options.

16.4 FXCs  shall be  capable  of being  matched  in part,  in which case the FXC
     covering the larger  amount of  underlying  currency  shall be deemed to be
     divided  into two  parts:  the part  that is  matched  and the part that is
     unmatched. Upon the one part becoming matched, the balance shall be treated
     as a new FXC.

17.  Set off
     At all times,  whether before or after the right to close-out FXCs (if any)
     has arisen in  addition  to any other of our rights we shall be entitled to
     apply any sum due from us to you on any account  whatsoever and in whatever
     currency in or towards satisfaction of any sum due to us from you.

18.  Withdrawals
     Any  withdrawal  made pursuant to the Facility  shall be made on a Business
     Day and shall be deemed to constitute a repeat of the warranties set out in
     this Appendix.

19.  Notices
     Any notices or communications under the Facility Letter shall be in writing
     and shall be delivered  personally  or sent by post,  telex or cable to the
     address given in the Facility  Letter or at such other  addresses which may
     be  notified  in  writing.  Proof of posting or  despatch  of any notice or
     communications to you shall be deemed to be proof of receipt:

     (a)  in the case of a letter three Business Days after having been posted;

     (b)  in the  case of a telex,  facsimile  or  cable,  on the  Business  Day
          immediately following the date of despatch.

20.  Invalidity
     If any of the provisions in the Facility Letter become invalid,  illegal or
     unenforceable  in any respect  under any law,  the validity and legality or
     enforceabliity of the remaining provisions shall not in any way be affected
     or impaired.

21.  Benefit of Facility Letter
     (a) We may assign any of our rights under the  Facility  Letter but you may
     not assign any of your rights.

     (b) We may  disclose  to a  potential  assignee  of all or any  part of our
     rights under the  Facility  Letter such  information  about you as we think
     fit.

22.  Joint and Several Liability

     Where you comprise more than one person,  all  representations,  warranties
     and  undertakings  given by you pursuant to the Facility shall be deemed to
     be given by each of you jointly and severally and all liabilities of you to
     us  pursuant  to the  Facility  shall be deemed to be the joint and several
     liabilities of each of you.

23.  Entire Agreement

     The Facility Letter and this Appendix shall constitute the entire agreement
     between  you and us in  respect  of the  Facility  and  shall  replace  all
     existing oral and written  agreements between you and us in respect hereof.
     In the event of any inconsistency  between the terms and conditions set out
     in this letter and our  standard  terms  applying  generally to FXCs or the
     terms of any specific FXC, the Facility Letter shall prevail.

THE PLEDGE       WHEREAS  the  pledgor  grants in favour of the pledgee a pledge
                 (hereinafter  the  "pledge  on  deposit")  under  the form of a
                 deposit of a countervalue of: (in numbers)

                 ---------------------------------------------------------------
                 (in letters)

                 (hereinafter  the "deposit",  which term shall include interest
                 accruing to the deposit).

                 WHEREAS  the  pledgor  has placed  the  deposit  with  CITIBANK
                 (LUXEMBOURG)  S.A.,   (hereinafter  the  "DEPOSITARY")  in  the
                 account opened by the pledgor with the depository,  the balance
                 of which,  if  different  from the  deposit,  is also placed in
                 favour of the pledgee  (this  balance  shall be  considered  as
                 being comprised in the term "deposit" as used hereinafter),  to
                 secure any and all payments due by the  pledgor/borrower to the
                 pledgee under the facility.

                 WHEREAS, furthermore, the pledgor is willing to grant in favour
                 of  the   pledgee  a  pledge   (hereinafter   the   "pledge  on
                 securities")  on  all  securities,  debentures,  notes,  bonds,
                 certificates  of deposit,  as well as all stock,  share capital
                 and  any  other  negotiable  rights  of  property,  whether  in
                 nominative  or in bearer  form,  whether  transferable  or not,
                 which the pledgor  holds now,  or may hold in the future,  with
                 the depository (hereinafter the "securities",  which term shall
                 include all rights and dividends  accruing to such  securities)
                 to secure the  pledgor's/borrower's  payment  obligations under
                 the   facility   as  well  as  all  other   present  or  future
                 indebtedness  of any  pledgor/borrower  vis-a-vis  the pledgee.
                 Except if expressly  otherwise  provided  for,  all  securities
                 shall be considered as being fungible.

                 WHEREAS  the  facility  shall at all  times be  secured  by the
                 aggregate   of  the  pledge  on  deposit   and  the  pledge  on
                 securities.

                 WHEREAS the facility may never exceed the loanable value of the
                 assets pledged by the pledgor to the pledgee.

                 WHEREAS the loanable  value of the  securities  and the deposit
                 shall be calculated  and monitored on a permanent  basis by the
                 depositary  as  agent of the  pledgee  in  accordance  with the
                 margin  table  set  out  in  appendix  hereto.  The  depositary
                 reserves the right to make any necessary  changes to the margin
                 table  based  on  the  quality,  liquidity,  marketability  and
                 concentration  of the pledged  assets.  The margin table of the
                 depositary  (as  applicable  from  time  to  time)  is  at  the
                 permanent disposal of the pledgor/borrower by the depositary.

                 WHEREAS the depositary  shall be the agent of and represent the
                 pledgee  in any acts and  deeds to be  undertaken  or signed in
                 order to give effect to this pledge  agreement.  The depositary
                 shall for instance be empowered to accept this pledge agreement
                 on behalf of the pledgee, to monitor the loanable value, and to
                 request and accept an additional  pledge of securities and/or a
                 pledge of deposit, pursuant to clause 3.2. of this agreement.

                 WHEREAS for all acts and deeds under this pledge agreement, the
                 depositary  (even if acting in his own name) shall be deemed to
                 act as an agent for the pledgee.

obligation  towards  the  pledgee  under the  facility,  or shall not have fully
complied  within  eight  days  from the date of a  summons  containing  a formal
request to satisfy the claims of the  pledgee  under the  facility,  the pledgee
shall be authorized to demand  payment,  transfer and delivery of the deposit in
view to  satisfy  its  secured  claims,  in  accordance  with  applicable  legal
provisions.

2. PLEDGE ON SECURITIES

2.1 The pledgor hereby pledges all securities to the pledgee, who accepts.

2.2 The  depositary  holds the  securities in surety in a special pledge account
and  guarantee  for the due and  punctual  payment of all amounts of  principal,
interest,  commissions,  fees and other  charges  including the repayment of all
judicial and extra  judicial  costs incurred for the recovery of any amounts due

the same shall become due and payable.

2.3 The pledgor hereby represents and warrants:

2.3.1 that the securities are free and clear of any claims, mortgages,  pledges,
liens or other encumbrances of any nature whatsoever,  and that the pledgor will

pledges, liens or other encumbrances of any nature whatsoever;

2.3.2 that the present  agreement  is not  contrary to any legal or  contractual
obligation  imposed  upon the  pledgor,  and that it creates  valid and  binding
obligations upon him.

2.4 If and when a formal  notice of repayment to the borrower and the pledgor by
the pledgee or the  depository,  by way of a  registered  letter,  has  remained
unsatisfied  for eight days, the pledgee may instruct the depositary to sell the
securities,  in accordance  with  applicable  legal  provisions,  and assign the
proceeds  by  privilege  to  the  reimbursement  of  the  said  debt  due by the
pledgor/borrower  to the  pledgee  upon  transfer  of the sales  proceeds by the
depository  to the  pledgee.

3. GENERAL

3.1 If the outstanding  amount of the facility exceeds or threatens to exceed at
any time, the loanable value of the deposit and the securities pledged in favour
of the pledgee,  the pledgor  undertakes,  within five days of first demand,  to
pledge,  mortgage,  transfer  and  assign to the  pledgee,  and  deliver  to the

extent  necessary  for the facility no longer to exceed or to threaten to exceed
the loanable value of the deposit and the securities.

clause 3.1 above, the pledgor herewith  unconditionally and irrevocably empowers
the pledgee to take all  appropriate  measures,  and in particular to effect all
transactions  in order to reduce the  outstanding  liabilities  to the  loanable
value of the deposit and the  securities,  or to render due and payable any sums
due to the pledgee by the pledgor, and to enforce this pledge agreement pursuant
to clause 1.5 and 2.4 above.

3.3 The pledgee shall not be limited in its  discretion to enforce the pledge on
deposit or the pledge on securities,  whether  simultaneously  or alternatively,
whether in full or in part.  The  enforcement,  in full or in part,  of the mere
pledge on deposit,  or of the pledge on securities,  as the case may be, does to
constitute  a waiver by the  pledgee  to any of his  rights  under the pledge on
securities and/or under the pledge on deposit, as the case may be.

3.4 For the duration of this pledge agreement,  the pledgor irrevocably empowers
the depositary to give the pledgee from time to time full disclosure  concerning
the details of the securities and the deposit. All communications by the pledgee
to either the borrower or the pledgor shall be deemed to be provided to both.

in case of the occurrence of any of the following events:

     -    any time,  indulgence,  waiver  or  consent  at any time  given to the
          pledgor/borrower or any other person;

     -    any  amendment  to any  of  the  facility  documents  or to any  other
          security or any guarantee or indemnity for the facility;

     -    the enforcement or absence of enforcement of claims for or the release
          of the facility or any other security,  guarantee or indemnity for the
          facility;

     -    the   dissolution,   amalgamation,   bankruptcy,   reconstruction   or
          re-organization of the pledgor/borrower or any other person.

3.6 The pledgee is explicitly  authorized to  communicate  openly and assign its
rights  hereunder  to all other  Citicorp/Citibank  entities  which are granting
credit to the  pledgor/borrower or which may be in possession of assets securing
such  credit or which are a party with or on behalf of the  pledgor/borrower  in
foreign exchange or securities transactions.

3.7 Generally,  the pledgor shall bear all costs,  expenses,  taxes,  duties and
similar  charges which shall be incurred to the pledgee by virtue of this pledge
agreement  now or in the future,  including any costs of  notification,  even to
foreign counties,  and including all court and legal expenses arising out of the

account.

3.8 This pledge  agreement shall in all respects be governed by and construed in
accordance with the laws of the Grand Dutchy of Luxembourg.

conditions,  which the pledgor declares having read and accepted, and which form
an integral part of this pledge  agreement  inasfar as applicable and consistent
with this pledge agreement.

proceedings  arising  out of or in  connection  with this  pledge  agreement  is
submitted  to the  jurisdiction  of the  Courts of  Luxembourg,  Grand  Duchy of
