               Advance shall be the Exchange Amount relating to the Tranche or,
               as the case may be, the Term B Advance under which such
               Refinancing Advance is to be made. The Facility Agent will, as
               soon as reasonably practicable, notify the Parent Guarantor and
               each Bank of the Exchange Amount and the relevant spot rate of
               exchange.

       5.1.4   On the Conversion Day:

                             applied in repayment of the outstanding Sterling
                             denominated Term A Advances under each of Tranches
                             A1 and A2; and

                             denominated Term B Advance.

       5.1.5   Each of the Parties authorises the Facility Agent to make the

                      damages, costs, expenses, losses and charges in relation
                      to or arising out of any Guarantee issued by the Issuing
                      Bank and each Bank Indemnity unless incurred as a result
                      of the negligence or wilful default of the Issuing Bank
                      or, as the case may be, the relevant Bank; and

               (b)    pay to the Issuing Bank for its own account or to the
                      Facility Agent for the account of the Banks, as the case
                      may be, on demand the amount of all payments made (whether
                      directly or by way of set-off, counterclaim or otherwise)
                      and all losses, costs and expenses suffered or incurred by
                      the Issuing Bank and the Banks under or by reason of each

                      a result of the negligence or wilful default of the
                      Issuing Bank or, as the case may be, the relevant Bank.

       5.10.2  The Issuing Bank is irrevocably authorised by each Borrower to

               the Issuing Bank without any reference to, or further authority
               from, any Borrower and without any enquiry into the justification
               for that demand or its validity. Any payment which the Issuing
               Bank shall make in accordance or purporting to be in accordance
               with such a demand shall be binding on each Borrower and be

               in which the Issuing Bank effected such compliance.

       5.10.3  The liability of any Borrower under this Clause 5.10 shall not be

               for this provision, would or might operate to exonerate or
               discharge that Borrower.

       5.10.4  The Borrower Indemnities shall constitute and be a continuing
               security to the Issuing Bank and the Banks and shall extend to
               each Guarantee issued by the Issuing Bank and each Bank Indemnity
               as they may be varied, modified, amended or extended.

       5.10.5  The Issuing Bank may claim under any Borrower Indemnity or under
               any Bank Indemnity in such order as the Issuing Bank shall think
               fit.

5.11   COUNTER INDEMNITY FROM THE BANKS

       5.11.1  Each Bank shall:

               (a)    indemnify the Issuing Bank and keep the Issuing Bank
                      indemnified (in the proportion which its Revolving Credit
                      Commitment bears to the Revolving Credit Commitments of
                      all the Banks) from and against all actions, suits,
                      proceedings, claims, demands, liabilities, damages, costs,
                      expenses, losses and charges in relation to or arising out
                      of any Guarantee issued by the Issuing Bank; and

               (b)    pay to the Issuing Bank on demand its relevant proportion
                      of the amount of all payments made (whether directly or by
                      way of set-off, counterclaim or otherwise) and all losses,
                      costs and expenses suffered or incurred by the Issuing
                      Bank under or by reason of each such Guarantee.

               For the purposes of paragraph (a), the Revolving Credit
               Commitment of the Bank which is the Overdraft Bank shall be
               deemed to be reduced by the amount of the Optional Overdraft
               Limit.

       5.11.2  The Issuing Bank is irrevocably authorised by each Bank to comply
               with the terms of any demand served or purporting to be served on
               the Issuing Bank pursuant to any Guarantee issued by the Issuing
               Bank without any reference to, or further authority from, any
               Bank and without any enquiry into the justification for that
               demand or its validity. Any payment which the Issuing Bank shall
               make in accordance or purporting to be in accordance with such a
               demand shall be binding on each Bank and be accepted by each Bank
               as conclusive and binding evidence that the Issuing Bank was
               liable to comply with the terms of such demand and was liable to
               do so in the manner and for the amount in which the Issuing Bank
               effected such compliance.

       5.11.3  The liability of any Bank under this Clause 5.11 shall not be
               discharged, lessened or impaired by any time being given or by
               any thing being done or other circumstance whatsoever which, but
               for this provision, would or might operate to exonerate or
               discharge that Bank.

       5.11.4  The Bank Indemnities shall constitute and be a continuing
               security to the Issuing Bank and shall extend to each Guarantee
               issued by the Issuing Bank as it may be varied, modified, amended
               or extended.

       5.11.5  The Issuing Bank may claim under any Bank Indemnity or under any
               Borrower Indemnity in such order as the Issuing Bank shall think
               fit.

       5.11.6  For the avoidance of doubt, each Bank Indemnity shall extend to
               any interest expressed to be due from a Borrower pursuant to
               Clause 5.12 (INTEREST ON PAYMENTS) in respect of any payment,
               loss, cost or expense made, suffered or incurred by the Issuing
               Bank under or by reason of any Guarantee issued by the Issuing
               Bank.

                                      -36-

5.12   INTEREST ON PAYMENTS

       Each Borrower shall pay to the Facility Agent for the account of the
       Issuing Bank or the account of the Banks, as the case may be, interest on
       the amount of each payment, loss, cost and expense made, suffered or
       incurred by the Issuing Bank or any Bank under or by reason of any
       Guarantee issued by the Issuing Bank and any Bank Indemnity from and
       including the date upon which such payment, loss, cost or expense is
       made, suffered or incurred up to and including the date upon which
       payment or reimbursement of such amount is demanded from that Borrower.
       The amount of such interest shall be calculated in accordance with Clause
       8.4 (DEFAULT INTEREST). For the avoidance of doubt, interest on sums
       demanded under Clause 5.10 (COUNTER INDEMNITY FROM THE BORROWERS) shall
       also accrue in accordance with Clause 8.4 (DEFAULT INTEREST).

6.     ALTERNATIVE CURRENCIES

6.1    REQUESTS FOR ALTERNATIVE CURRENCY

       Subject to Clause 6.2 (AVAILABILITY), a Borrower may request in a
       Drawdown Notice that a Revolving Advance be denominated in an Alternative
       Currency.

6.2    AVAILABILITY

       A Borrower may not request that a Revolving Advance be denominated in an
       Alternative Currency unless the Facility Agent has confirmed to that
       Borrower that the Alternative Currency is available for drawing under the
       Revolving Credit Facility.

6.3    NOTIFICATION TO BANKS

       The Facility Agent shall promptly notify each Bank of the currency and
       the Original Dollar Amount of each Revolving Advance.

6.4    NO ALTERNATIVE CURRENCY

       If, no later than 10.00 a.m. on the second Business Day before the first
       day of an Interest Period in relation to a Revolving Advance which is
       proposed to be denominated in an Alternative Currency, a Bank notifies
       the Facility Agent that:

       6.4.1   for whatever reason it is impracticable for that Bank to fund its
               Participation in that Revolving Advance in the proposed
               Alternative Currency in the ordinary course of business in the
               London interbank market; or

       6.4.2   central bank or other governmental authorisation in the country
               of the proposed Alternative Currency is required to permit its
               use by that Bank for the making of that Revolving Advance and the
               authorisation has not been obtained or is not in full force and
               effect or is subject to unacceptable conditions; or

       6.4.3   the use of the proposed Alternative Currency is restricted or
               prohibited by any request, directive, regulation or guideline of
               any governmental body, agency, department or regulatory or other
               authority (whether or not having the force of law) in accordance
               with which that Bank is accustomed to act,

       the Facility Agent shall notify the Parent Guarantor and the Banks by
       11.00 a.m. on the same day. In this event, the Parent Guarantor and the
       Banks may agree that the Revolving Advance shall not be made, PROVIDED
       THAT, in the absence of such agreement

                                      -37-

<Page>


       by 12.00 noon on the same day, the Revolving Advance shall be denominated
       in Dollars during that Interest Period.

6.5    EXCHANGE RATE MOVEMENTS

       6.5.1   Subject to sub-clause 7.2.4 of Clause 7.2 (UTILISATIONS), if on
               any Quarter Date:

               (a)    the Total Revolving Credit Amount exceeds the Revolving
                      Credit Facility Limit; and

               (b)    the Facility Agent determines that the Dollar Equivalent
                      (calculated on that Quarter Date) of the Guaranteed Amount
                      of all Guarantees denominated in an Alternative Currency
                      shall be greater than the Original Dollar Amount of those
                      Guarantees by 5 per cent. or more,

               the relevant Borrowers shall, within 2 Business Days of receiving
               the Facility Agent's demand so to do, pay to the credit of their
               respective Collateral Accounts (as defined in sub-clause 6.5.3)
               such amounts in the relevant Alternative Currencies to ensure
               that the aggregate of (i) the Original Dollar Amount of those
               Guarantees and (ii) the Dollar Equivalent (calculated on that
               Quarter Date) of all sums standing to the credit of the
               Collateral Accounts on that Quarter Date shall, after the
               crediting of such amounts, equal the Dollar Equivalent
               (calculated on that Quarter Date) of the Guaranteed Amount of
               those Guarantees.

       6.5.2   On each Quarter Date (and on the Final Repayment Date or such
               earlier date on which the Revolving Credit Facility is cancelled
               in accordance with the terms of this Agreement), PROVIDED THAT no
               Default has occurred and is continuing, the Borrowers may
               withdraw such amounts standing to the credit of the Collateral
               Accounts (as determined by the Facility Agent and comprised of
               such Alternative Currencies as the Facility Agent may select) to
               ensure that, after payment of such amounts, the aggregate of (a)
               the Original Dollar Amount of all Guarantees denominated in an
               Alternative Currency and (b) the Dollar Equivalent (calculated on
               that Quarter Date) of all sums, if any, standing to the credit of
               the Collateral Accounts on that Quarter Date is equal to the
               Dollar Equivalent (calculated on that Quarter Date) of the
               Guaranteed Amount of those Guarantees.

       6.5.3   In this Clause 6.5, a "COLLATERAL ACCOUNT" means, in relation to
               a Borrower and an Alternative Currency, an account of that
               Borrower in that currency held with such bank as the Facility
               Agent may nominate and designated as being in respect of
               Guarantees issued by the Issuing Bank at the request of that
               Borrower.

       6.5.4   On the first occasion a Borrower is obliged to make a payment to
               a Collateral Account, it shall open that Collateral Account and
               (to the extent it has not already done so) charge the same to the
               Facility Agent (as agent and trustee for itself, the Issuing Bank
               and the Banks) on terms satisfactory to the Facility Agent acting
               reasonably.

                                      -38-

       6.5.5   Except as expressly permitted in this Clause 6.5, no Borrower may
               withdraw any amount from a Collateral Account.

7.     THE OPTIONAL OVERDRAFT FACILITY

7.1    NATURE OF FACILITY

       7.1.1   The Optional Overdraft Facility forms part of the Revolving
               Credit Facility and, subject to the terms of this Agreement,
               shall be available for utilisation by any Borrower, PROVIDED
               THAT, without prejudice to the continued operation of the
               Revolving Credit Facility, the Optional Overdraft Facility may be
               terminated and cancelled (in whole or in part) by the Overdraft
               Bank at any time and the Optional Overdraft Limit shall be
               reduced by the amount so cancelled.

       7.1.2   The Optional Overdraft Facility shall be made available by the
               Overdraft Bank in a maximum amount equal to the Optional
               Overdraft Limit. Prior to the Optional Overdraft Facility being
               terminated, the Bank which is the Overdraft Bank shall not
               transfer or assign any of its Revolving Credit Commitment if the
               relevant transfer or assignment would result in it ceasing to
               have a Revolving Credit Commitment at least equal to the Optional
               Overdraft Limit.

       7.1.3   The Optional Overdraft Facility shall cease to be available on
               the Final Repayment Date in relation to the Revolving Credit
               Facility or such earlier date on which it is cancelled in
               accordance with the terms of this Agreement.

       7.1.4   Each Borrower shall complete such mandate and other like
               documents in respect of the Optional Overdraft Facility as the
               Overdraft Bank may reasonably require.

7.2    UTILISATION

       7.2.1   Subject to the terms of this Agreement, the Overdraft Bank agrees
               to make the Optional Overdraft Facility available on a revolving
               basis to the Borrowers to be utilised on any Business Day:

               (a)    by way of overdraft on usual banking terms including a
                      term that amounts outstanding by way of overdraft are
                      repayable on demand;

               (b)    by way of issue of Guarantees;

               (c)    by way of FFE Contracts; and

               (d)    by way of such other facilities or financial accommodation
                      as the Overdraft Bank and the Parent Guarantor may agree.

       7.2.2   Subject to sub-clause 7.2.4 of this Clause 7.2, no utilisation of
               the Optional Overdraft Facility under sub-clause 7.2.1 shall be
               made if it would result in:

               (a)    the aggregate of (i) the Original Dollar Amount of all
                      Revolving Advances and Guarantees issued by the Issuing
                      Bank and (ii) the Overdraft Outstandings exceeding the
                      Revolving Credit Facility Limit; or

               (b)    the Overdraft Outstandings exceeding the Optional
                      Overdraft Limit.

                                      -39-

<Page>


       7.2.3   For the avoidance of doubt, the Overdraft Bank may, without
               liability, return cheques unpaid if the payment of those cheques
               would result in a breach of sub-clause 7.2.2 of this Clause 7.2.

       7.2.4   The Optional Overdraft Limit may only be increased with the prior
               consent of the Majority Banks and the Overdraft Bank, PROVIDED
               THAT the Overdraft Bank may, without the consent of the Majority
               Banks, allow the Optional Overdraft Limit to be exceeded by a
               maximum of US$100,000 for a period not exceeding 5 days.

7.3    FFE CONTRACTS

       7.3.1   An FFE Contract shall:

               (a)    be on the usual terms of the Overdraft Bank;

               (b)    be of a duration of not more than 12 months;

               (c)    be on terms that the Overdraft Bank shall have no
                      obligation to make payments under it at any time after the
                      Final Repayment Date in relation to the Revolving Credit
                      Facility unless the OVERDRAFT Bank (in its sole discretion
                      and upon such terms as it requires) agrees otherwise; and

               (d)    only be entered into on a Business Day.

       7.3.2   All obligations and liabilities owing to the Overdraft Bank under
               or in respect of an FFE Contract shall be deemed to be
               obligations and liabilities owing to the Overdraft Bank under
               this Agreement.

7.4    GUARANTEES

       7.4.1   The Overdraft Bank shall not be obliged to issue any Guarantee
               unless it has approved the form of the proposed Guarantee.

       7.4.2   No Guarantee shall be issued by the Overdraft Bank under which a
               claim could be made at a time after the Final Repayment Date in
               relation to the Revolving Credit Facility unless the Overdraft
               Bank (in its sole discretion and upon such terms as its requires)
               agrees otherwise.

       7.4.3   Each Guarantee issued by the Overdraft Bank shall be denominated
               in Dollars and shall state on its face the maximum amount payable
               under it and its expiry date.

       7.4.4   A Guarantee shall only be issued by the Overdraft Bank on a
               Business Day.

7.5    COUNTER INDEMNITY FROM THE BORROWERS

       7.5.1   Each Borrower shall:

               (a)    indemnify the Overdraft Bank and keep the Overdraft Bank
                      indemnified from and against all actions, suits,
                      proceedings, claims, demands, liabilities, damages, costs,
                      expenses, losses and charges in relation to or arising out
                      of any Guarantee issued by the Overdraft Bank on its
                      behalf; and

                                      -40-

<Page>


               (b)    pay to the Overdraft Bank on demand the amount of all
                      payments made (whether directly or by way of set-off,
                      counterclaim or otherwise) and all losses, costs and
                      expenses suffered or incurred by the Overdraft Bank under
                      or by reason of each such Guarantee.

       7.5.2   The Overdraft Bank is irrevocably authorised by each Borrower to
               comply with the terms of any demand served or purporting to be
               served on the Overdraft Bank pursuant to any Guarantee issued by
               the Overdraft Bank without any reference to, or further authority
               from, any Borrower and without any enquiry into the justification
               for that demand or its validity. Any payment which the Overdraft
               Bank shall make in accordance or purporting to be in accordance
               with such a demand shall be binding on each Borrower and be
               accepted by each Borrower as conclusive and binding evidence that
               the Overdraft Bank was liable to comply with the terms of such
               demand and was liable to do so in the manner and for the amount
               in which the Overdraft Bank effected such compliance.

       7.5.3   The liability of any Borrower under this Clause 7.5 shall not be
               discharged, lessened or impaired by any time being given or by
               anything being done or other circumstance whatsoever which, but
               for this provision, would or might operate to exonerate or
               discharge that Borrower.

       7.5.4   The indemnity contained in this Clause 7.5 shall constitute and
               be a continuing security to the Overdraft Bank and shall extend
               to each Guarantee issued by the Overdraft Bank as it may be
               varied, modified, amended or extended.

7.6    INTEREST ON PAYMENTS

       Each Borrower shall pay interest on the amount of each payment, loss,
       cost and expense made, suffered or incurred by the Overdraft Bank under
       or by reason of any Guarantee issued by the Overdraft Bank on its behalf
       from and including the date upon which such payment, loss, cost or
       expense is made, suffered or incurred up to and including the date upon
       which payment or reimbursement of such amount is demanded from that
       Borrower which demand shall be made promptly by the Overdraft Bank upon
       it making the relevant payment or, as the case may be, becoming aware of
       the relevant loss, cost or expense. The amount of such interest shall be
       calculated in accordance with Clause 8.4 (DEFAULT INTEREST). For the
       avoidance of doubt, interest on sums demanded under this Clause 7.5 shall
       also accrue in accordance with Clause 8.4 (DEFAULT INTEREST).

8.     INTEREST

8.1    INTEREST RATE

       Interest shall accrue on each Advance from and including the relevant
       Drawdown Date to but excluding the date the Advance is repaid at the rate
       determined by the Facility Agent to be the aggregate of:

       8.1.1   the Margin;

       8.1.2   LIBOR; and

       8.1.3   the Additional Cost Rate.

8.2    MARGIN RATCHET IN RELATION TO THE TERM A LOAN FACILITY AND THE REVOLVING
       CREDIT FACILITY

       8.2.1   The Margin in relation to the Term A Loan Facility and the

       8.2.4   In relation to a Quarter, for the purpose of this Clause 8.2, any
               reduction or increase in the Margin in relation to the Term A
               Loan Facility and the Revolving Credit Facility shall be

               Facility Agent of the Management Accounts for the last month in
               the Relevant Period. Any reduction or increase shall, subject to

               control of the Parent Guarantor) until the date once such
               Management Accounts have been so delivered, be reinstated to 2.25
               per cent.

       8.2.5   Notwithstanding any other term of this Clause 8.2, at the time a

8.3    INTEREST PERIODS

       8.3.1   Interest payable on each Advance shall be calculated by reference
               to Interest Periods of 1, 3 or 6 months' duration (or such other
               Interest Period as the Facility Agent, acting on the instructions
               of all the Banks, may allow) as selected by the relevant Borrower
               in accordance with this Clause 8.3 PROVIDED THAT (1) during the
               Syndication Period a Borrower shall only select an Interest
               Period of 1 month's duration or such other agreed period as to
               assist the syndication process and (2) the first Interest Period
               for each Term Advance made on the Drawdown Date shall be 2
               Business Days.

       8.3.2   The relevant Borrower shall select an Interest Period for a
               Revolving Advance in the relevant Drawdown Notice. The relevant
               Borrower may select an Interest Period for a Term Advance in
               either the Drawdown Notice (in the case of the first Interest
               Period for that Advance) or (in the case of any subsequent
               Interest Period for that Advance) by notice received by the
               Facility Agent no later than 3 Business Days before the
               commencement of that Interest Period.

       8.3.3   In respect of Term Advances, interest shall be calculated by
               reference to successive Interest Periods. The first Interest
               Period for a Term Advance shall begin on the Drawdown Date of
               that Advance. Each succeeding Interest Period for that Advance
               shall begin on the Interest Date of the previous Interest Period.

       8.3.4   Swiss Newco may, by notice to the Facility Agent at least 3
               Business Days before an Interest Date relating to a Term Advance,
               elect that that Term Advance be split into two or more Term
               Advances of at least US$2,000,000 each (and being multiples of
               US$500,000) (or, in the case of Tranche A2, being of at least Yen
               240,000,000 each and multiples of Yen 60,000,000) or, in the case
               of a Term A Advance such lesser amount equal to the amount of the
               Term A Instalment falling due on the next Term A Instalment
               Repayment Date or, in the case of a Term B Advance, such lesser
               amount equal to the amount of the Term B Instalment falling due
               on the next Term B Instalment Repayment Date. Any such notice
               shall specify the Interest Periods applicable to those Term
               Advances and shall take effect in accordance with its terms from
               that Interest Date, PROVIDED THAT there shall not be more than 5
               Term Advances outstanding at any one time.

       8.3.5   Subject to the other terms of this Agreement, if the Interest
               Periods for two or more Term A Advances under the same Tranche or
               Term B Advances under the same Tranche end on the same day those
               Term A Advances or Term B Advances shall be deemed to be a single
               Term A Advance under the same Tranche or, as the case may be,
               Term B Advance under the same Tranche from that day.

       8.3.6   If a Borrower fails to select an Interest Period for an Advance
               in accordance with sub-clause 8.3.2, that Interest Period shall,
               subject to the other provisions of this Clause 8.3 (INTEREST
               PERIODS), be 3 months.

                                      -43-

<Page>


       8.3.7   If an Interest Period would otherwise end on a day which is not a
               Business Day, that Interest Period shall instead end on the next
               Business Day in the same calendar month (if there is one) or the
               preceding Business Day (if there is not).

       8.3.8   If an Interest Period begins on the last Business Day in a
               calendar month or on a Business Day for which there is no
               numerically corresponding day in the calendar month in which that
               Interest Period is to end, it shall end on the last Business Day
               in that later calendar month.

       8.3.9   In respect of Term Advances, the Parent Guarantor shall select
               such Interest Periods to ensure that on each Term A Instalment
               Repayment Date or, as the case may be, Term B Instalment
               Repayment Date there are Term A Advances under the same Tranche
               or, as the case may be, Term B Advances under the same Tranche
               with an Interest Period ending on that Term A Instalment
               Repayment Date or, as the case may be, Term B Instalment
               Repayment Date which are, in aggregate, at least equal to the
               Term A Instalment or, as the case may be, Term B Instalment due
               on that Term A Instalment Repayment Date or, as the case may be,
               Term B Instalment Repayment Date.

       8.3.10  If an Interest Period for an Advance would otherwise extend
               beyond the Final Repayment Date for the Facility under which such
               Advance is made, it shall be shortened so that it ends on that
               Final Repayment Date.

8.4    DEFAULT INTEREST

       8.4.1   If a Borrower fails to pay any amount payable under any Financing
               Document on the due date, it shall pay default interest on the
               overdue amount from the due date to the date of actual payment
               calculated by reference to successive Interest Periods (each of
               such duration as the Facility Agent may select and the first
               beginning on the relevant due date) at the rate per annum being
               the aggregate of (a) 2.00 per cent. per annum, (b) the Margin,
               (c) LIBOR and (d) the Additional Cost Rate.

       8.4.2   So long as the overdue amount remains unpaid, the default
               interest rate shall be recalculated in accordance with the
               provisions of this Clause 8.4 on the last day of each such
               Interest Period and any unpaid interest shall be compounded at
               the end of each Interest Period.

8.5    GUARANTEE COMMISSION AND FRONTING FEES

       8.5.1   Commission in respect of all Bank Indemnities shall:

               (a)    accrue from day to day on an amount equal to the aggregate
                      Original Dollar Amount of all Guarantees issued by the
                      Issuing Bank at a rate per annum equal to the Margin in
                      respect of the Revolving Credit Facility;

               (b)    be calculated on the basis of actual days elapsed and a
                      360 day year (or such number of days as is market practice
                      for the relevant currency); and

               (c)    be paid by the relevant Borrower to the Facility Agent for
                      the account of the Banks (PRO RATA to their Revolving

                      on the Issue Date of the first Guarantee issued by the
                      Issuing Bank.

               Optional Overdraft Facility shall accrue at the rate per annum
               which is the aggregate of:

               (a)    the Margin; and

               (b)    the most recently published base rate of the Overdraft
                      Bank.

       8.6.3   In respect of each Guarantee issued by the Overdraft Bank, the
               Borrower on whose behalf that Guarantee has been issued, shall
               pay a commission to the Overdraft Bank on the Guaranteed Amount
               of that Guarantee, in the case of Guarantees, at a rate per annum
               equal to the Margin and in all other cases at a rate per annum
               determined in accordance with the Overdraft Bank's usual charging
               scales as notified to the Parent Guarantor but not exceeding the

       8.6.4   In respect of each FFE Contract, the relevant Borrower shall pay
               fees and commissions to the Overdraft Bank in accordance with the
               Overdraft Bank's usual charging scales as notified to the Parent
               Guarantor from time to time for entering into forward foreign

               last sentence of sub-clause 15.2.1 of Clause 15.2 (ACCELERATION,
               ETC.)).

               "TOTAL REMUNERATION" means the aggregate remuneration by way of

8.8    CALCULATION AND PAYMENT OF INTEREST

       8.8.1   At the beginning of each Interest Period, the Facility Agent
               shall notify the Banks and the relevant Borrower of the duration
               of the Interest Period and the rate and amount of interest
               payable for the Interest Period (but in the case of any default
               interest calculated under Clause 8.4 (DEFAULT INTEREST), any such
               notification need not be made more frequently than weekly). Each
               notification shall set out in reasonable detail the basis of
               computation of the amount of interest payable.

       8.8.2   Interest due from a Borrower under this Agreement shall:

               (a)    accrue from day to day at the rate calculated under this

                      may be) in arrear on the last day of each Interest Period,
                      PROVIDED THAT for any Interest Period which is for longer
                      than 6 months, the relevant Borrower shall also pay
                      interest 6 monthly in arrear during that Interest Period;

               (c)    be calculated on the basis of the actual number of days
                      elapsed and a 360 day year or, if different, such number
                      of days as is market practice for the relevant currency;
                      and

               (d)    be payable both before and after judgment.

                                    the Facility Agent and the Issuing Bank.

       10.1.2  If it is or becomes illegal for the Issuing Bank to issue or
               leave outstanding any Guarantee, the Revolving Credit Facility
               and the Optional Overdraft Facility shall cease to be available
               for the issue of Guarantees and the Borrowers shall use their
               best endeavours to procure the release of each Guarantee
               outstanding at such time.

10.2   INCREASED COSTS

       10.2.1  If, after the date of this Agreement, a Change occurs which
               causes an Increased Cost (as defined in sub-clause 10.2.3) to a
               Bank (or any company of which that Bank is a Subsidiary) then
               each Borrower shall pay (as additional interest) to the Facility
               Agent (for the account of that Bank) within 5 Business Days of
               demand all amounts which that Bank certifies to be necessary to
               compensate that Bank (or any company of which that Bank is a
               Subsidiary) for the Increased Cost.

       10.2.2  Any demand made under sub-clause 10.2.1 shall be made by the
               relevant Bank through the Facility Agent and shall set out in
               reasonable detail so far as is practicable the basis of
               computation of the Increased Cost.

       10.2.3  In this Clause 10.2:

               "INCREASED COST" means any cost to, or reduction in the amount
               payable to, or reduction in the return on capital or regulatory
               capital achieved by, a Bank (or any company of which that Bank is
               a Subsidiary) to the extent that it arises, directly or
               indirectly, as a result of the Change and is attributable to the
               Commitment of that Bank or its Participation in the Facilities or
               the funding of that Bank's Participation in any Advance
               including:

               (a)    any Tax Liability (other than Tax on Overall Net Income)
                      incurred by that Bank;

               (b)    any changes (other than changes made voluntarily by that
                      Bank) in the basis or timing of Taxation of that Bank in
                      relation to its Commitment or Participation in the
                      Facilities or to the funding of that Bank's Participation
                      in any Advance;

               (c)    the cost to that Bank (or any company of which that Bank
                      is a Subsidiary) of complying with, or the reduction in
                      the amount payable to or reduction in the return on
                      capital or regulatory capital achieved by that Bank (or
                      any company of which that Bank is a Subsidiary) as a
                      result of complying with, any capital adequacy or similar
                      requirements howsoever arising,

                                      -52-

<Page>


                      including as a result of an increase in the amount of
                      capital to be allocated to any Facility or of a change to
                      the weighting of that Bank's Commitment or Participation
                      in any Facility;

               (d)    the cost to that Bank of complying with any reserve, cash
                      ratio, special deposit or liquidity requirements (or any
                      other similar requirements); and

               (e)    the amount of any fees payable by that Bank to any
                      supervisory or regulatory authority.

               "TAX LIABILITY" means, in respect of any person:

               (a)    any liability or any increase in the liability of that
                      person to make any payment of or in respect of Tax;

               (b)    the loss of any relief, allowance, deduction or credit in
                      respect of Tax which would otherwise have been available
                      to that person;

               (c)    the setting off against income, profits or gains or
                      against any Tax liability of any relief, allowance,
                      deduction or credit in respect of Tax which would
                      otherwise have been available to that person; and

               (d)    the loss or setting off against any Tax liability of a
                      right to repayment of Tax which would otherwise have been
                      available to that person.

               For the purposes of this definition of "Tax Liability", any
               question of whether or not any relief, allowance, deduction,
               credit or right to repayment of Tax has been lost or set off, and
               if so, the date on which that loss or set-off took place, shall
               be conclusively determined by the relevant person.

               "TAX ON OVERALL NET INCOME" means, in relation to a Bank, Tax
               (other than Tax deducted or withheld from any payment) imposed on
               the net profits of that Bank by the jurisdiction in which its
               Lending Office or its head office is situated.

       10.2.4  The Borrowers shall not be obliged to make a payment in respect
               of an Increased Cost under this Clause 10.2:

               (a)    if and to the extent that the Increased Cost has been
                      compensated for by the payment of the Additional Cost Rate
                      or the operation of Clause 11.9 (GROSSING-UP);

               (b)    if and to the extent that the Increased Cost is the result
                      of the negligence or wilful default of the relevant Bank
                      in complying with any law or regulation;

               (c)    if and to the extent that the Increased Cost arises as a
                      direct result of a failure by the relevant Bank to file
                      any relevant tax form or to provide any statements which
                      have been reasonably requested by the relevant authorities
                      within a reasonable time following a Change and which is
                      within the control of such Bank to file or provide, as the
                      case may be; or

                                      -53-

<Page>


               (d)    if and to the extent that the Increased Cost is
                      compensated for under any other provision of this
                      Agreement.

       10.2.5  If the Borrowers are required to pay any amount to a Bank under
               this Clause 10.2, then, without prejudice to that obligation and
               so long as the circumstances giving rise to the relevant
               Increased Cost are continuing and subject to the Parent Guarantor
               giving the Facility Agent and that Bank not less than 5 Business
               Days' prior notice (which shall be irrevocable), the Borrowers
               may (a) prepay all, but not part, of that Bank's Participation in
               the Advances together with accrued interest on the amount prepaid
               and (b) pay to one or more accounts nominated by the Facility
               Agent amounts in the relevant currencies equal, in aggregate, to
               that Bank's actual and contingent liabilities under its Bank
               Indemnity and shall charge such accounts in favour of the
               Facility Agent on terms reasonably satisfactory to the Facility
               Agent and the Issuing Bank. Any such prepayment shall be subject
               to Clause 24.1 (BREAKAGE COSTS INDEMNITY). On any such prepayment
               the Commitment of the relevant Bank shall be automatically
               cancelled.

10.3   MARKET DISRUPTION

       10.3.1  If, in relation to an Advance and a particular Interest Period:

               (a)    the Facility Agent determines that, because of
                      circumstances affecting the London interbank market
                      generally, reasonable and adequate means do not exist for
                      ascertaining LIBOR for that Advance for that Interest
                      Period; or

               (b)    the Facility Agent has been notified by a group of Banks
                      whose Term A Loan Commitments, Term B Loan Commitments or,
                      as the case may be, Revolving Credit Commitments together
                      exceed 33 per cent. of the Total Term A Loan Commitments,
                      Total Term B Loan Commitments or, as the case may be,
                      Total Revolving Credit Commitments that in their opinion:

                      (i)    matching deposits may not be available to them in
                             the London interbank market in the ordinary course
                             of business to fund their Participations in that
                             Advance for that Interest Period; or

                      (ii)   the cost to them of obtaining matching deposits in
                             the London interbank market would be in excess of
                             LIBOR for that Interest Period,

               the Facility Agent shall promptly notify the Parent Guarantor and
               the Banks of that event (such notice being a "MARKET DISRUPTION
               NOTICE").

       10.3.2  If a Market Disruption Notice applies to a proposed Revolving
               Advance (which is not to be used to repay another Revolving
               Advance), that Advance shall not be made. Instead, the Facility
               Agent and the Parent Guarantor shall immediately enter into
               negotiations for a period of not more than 30 days with a view to
               agreeing a substitute basis for calculating the interest rate for
               the Advance or for funding the Advance. Any substitute basis
               agreed by the

                                      -54-

<Page>


               Facility Agent (with the consent of all the Banks) and the Parent
               Guarantor shall take effect in accordance with its terms and be
               binding on all the Parties.

       10.3.3  If a Market Disruption Notice applies to a Term Advance or a
               Revolving Advance, then:

               (a)    the Facility Agent and the Parent Guarantor shall
                      immediately enter into negotiations for a period of not
                      more that 30 days with a view to agreeing a substitute
                      basis for calculating the rate of interest for the Advance
                      or for funding the Advance;

               (b)    any substitute basis agreed under sub-clause 10.3.3(a) by
                      the Facility Agent (with the consent of all the Banks) and
                      the Parent Guarantor shall take effect in accordance with
                      its terms and be binding on all the Parties;

               (c)    if no substitute basis is agreed under sub-clause
                      10.3.3(a), then, subject to sub-clause 10.4, each Bank
                      shall (through the Facility Agent) certify before the last
                      day of the Interest Period to which the Market Disruption
                      Notice relates a substitute basis for maintaining its
                      Participation in the Advance which shall reflect the cost
                      to the Bank of funding its Participation in the Advance
                      from whatever sources it reasonably selects plus the
                      Margin and (if applicable) Additional Cost Rate; and

               (d)    each substitute basis so certified shall be binding on the
                      relevant Borrower and the certifying Bank and treated as
                      part of this Agreement.

10.4   If no substitute basis is agreed under sub-clause 10.3.3(a), then, so
       long as the circumstances giving rise to the Market Disruption Notice
       continue and subject to the Parent Guarantor giving the Facility Agent
       and the Banks not less than 5 Business Days' prior notice (which shall be
       irrevocable), the relevant Borrower may prepay the Advance to which the
       Market Disruption Notice applies together with accrued interest on the
       amount prepaid. Any such prepayment shall be subject to Clause 24.1
       (BREAKAGE COSTS INDEMNITY).

10.5   MITIGATION

       10.5.1  If any circumstances arise in respect of any Bank which would, or
               upon the giving of notice would, result in the operation of
               Clause 10.1 (ILLEGALITY), 10.2 (INCREASED COSTS), 10.3 (MARKET
               DISRUPTION) or 11.9 (GROSSING-UP) to the detriment of any
               Borrower, then that Bank shall:

               (a)    promptly upon becoming aware of those circumstances and
                      their results, notify the Facility Agent and the Parent
                      Guarantor; and

               (b)    in consultation with the Facility Agent and the Parent
                      Guarantor, take all such steps as are reasonably open to
                      it to mitigate the effects of those circumstances
                      (including changing its Lending Office or consulting with
                      the Parent Guarantor with a view to transferring some or
                      all of its rights and obligations under this Agreement to
                      another bank or other financial institution acceptable to
                      the Parent Guarantor) in a manner which will

                                      -55-

<Page>


                      avoid the circumstances in question and on terms
                      acceptable to the Facility Agent, the Parent Guarantor and
                      that Bank,

               PROVIDED THAT no Bank shall be obliged to take any steps which in
               its opinion would or might have an adverse effect on its business
               or financial condition or the management of its Tax affairs or
               cause it to incur any material costs or expenses except to the
               extent that such Bank is indemnified and secured for such costs
               and expenses to its reasonable satisfaction.

       10.5.2  Nothing in this Clause 10.5 shall limit, reduce, affect or
               otherwise qualify the rights of any Bank or the obligations of
               the Borrowers under Clause 10.1 (ILLEGALITY), 10.2 (INCREASED
               COSTS), 10.3 (MARKET DISRUPTION) or 11.9 (GROSSING-UP).

10.6   CERTIFICATES

       The certificate or notification of the Facility Agent or, as the case may
       be, the relevant Bank as to any of the matters referred to in this Clause
       10 shall be in reasonable detail and shall be conclusive and binding on
       the Borrowers except for any manifest error.

11.    PAYMENTS

11.1   PLACE AND TIME

       All payments by a Borrower or a Bank under this Agreement shall be made
       to the Facility Agent to its account at such office or bank at such time
       as the Facility Agent may notify the Borrowers or the Banks for this
       purpose PROVIDED THAT all payments to be made by a Borrower to the
       Overdraft Bank in relation to the Optional Overdraft Facility shall be
       made in accordance with usual procedures for the operation of the
       Optional Overdraft Facility.

11.2   FUNDS

       All payments to the Facility Agent under this Agreement shall be made for
       value on the due date in freely transferable and readily available funds.

11.3   DISTRIBUTION

       11.3.1  Each payment received by the Facility Agent under this Agreement
               for another Party shall, subject to sub-clauses 11.3.2 and
               11.3.3, be made available by the Facility Agent to that Party by
               payment (on the date and in the currency and funds of receipt) to
               its account with such office or bank in the principal financial
               centre of the country of the relevant currency (or, in the case
               of euros, such financial centre in the Participating Member
               States as the Facility Agent shall reasonably specify) as it may
               notify to the Facility Agent for this purpose by not less than 5
               Business Days' prior notice.

       11.3.2  The Facility Agent may apply any amount received by it for a
               Borrower in or towards payment (on the date and in the currency
               and funds of receipt) of any amount due from that Borrower under
               this Agreement or in or towards the purchase of any amount of any
               currency to be so applied.

       11.3.3  Where a sum is to be paid to the Facility Agent under this
               Agreement for another Party, the Facility Agent is not obliged to
               pay that sum to that Party

                                      -56-

<Page>


               until it has established that it has actually received that sum.
               The Facility Agent may, however, assume that the sum has been
               paid to it in accordance with this Agreement, and, in reliance on
               that assumption, make available to that Party a corresponding
               amount. If the sum has not been made available but the Facility
               Agent has paid a corresponding amount to another Party, that
               Party shall immediately on demand by the Facility Agent refund
               the corresponding amount together with interest on that amount
               from the date of payment to the date of receipt, calculated at a
               rate determined by the Facility Agent to reflect its cost of
               funds.

       11.3.4  Notwithstanding the provisions of this Clause 11.3, the Facility
               Agent shall not be liable to any Borrower or any Bank for the
               failure, or the consequences of any failure, of any euro
               cross-border payment system to effect same-day settlement to an
               account of any Borrower or any Bank.

11.4   BUSINESS DAYS

       If a payment under this Agreement is due on a day which is not a Business
       Day, the due date for that payment shall instead be the next Business Day
       in the same calendar month (if there is one) or the preceding Business
       Day (if there is not).

11.5   CURRENCY

       In this Agreement, subject to any EMU Legislation:

       11.5.1  all payments by a Borrower in respect of an Advance, whether of
               interest or principal, shall be made in the currency (or the
               denomination of the currency) in which that Advance is
               denominated;

       11.5.2  all payments relating to costs, losses, expenses or Taxes shall
               be made in the currency in which the relevant costs, losses,
               expenses or Taxes were incurred; and

       11.5.3  any other amount payable under this Agreement shall, except as
               otherwise provided, be made in Dollars.

11.6   ACCOUNTS AS EVIDENCE

       Each Bank shall maintain in accordance with its usual practice an account
       which shall, as between the Borrowers and that Bank, be prima facie
       evidence of the amounts from time to time advanced by, owing to, paid and
       repaid to that Bank under this Agreement.

11.7   PARTIAL PAYMENTS

       11.7.1  If the Facility Agent receives a payment insufficient to
               discharge all the amounts then due and payable by a Borrower

               towards the obligations of that Borrower in the following order:

               (a)    first, in or towards payment of any unpaid costs and
                      expenses of the Facility Agent under this Agreement;

               (b)    second, in or towards payment PRO RATA of any accrued

                      Agreement;

               (c)    third, in or towards payment PRO RATA of any principal due
                      by that Borrower but unpaid under this Agreement; and

               (d)    fourth, in or towards payment PRO RATA of any other sum
                      due by that Borrower but unpaid under the Financing
                      Documents.

       11.7.2  The Facility Agent shall, if so directed by all the Banks, vary
               the order set out in sub-clauses 11.7.1(c) to 11.7.1(d).

       11.7.3  Sub-clauses 11.7.1 and 11.7.2 shall override any appropriation
               made by any Borrower.

11.8   SET-OFF AND COUNTERCLAIM

       All payments by any Borrower under this Agreement shall be made without
       set-off or counterclaim.

11.9   GROSSING-UP

               Party pursuant to or in connection with any Financing Document
               shall be paid in full free and clear of all deductions or
               withholdings whatsoever except only as may be required by law.

       11.9.2  If any deduction or withholding is required by law in respect of
               any payment due from a Borrower to any Finance Party pursuant to
               or in connection with any Financing Document, that Borrower
               shall:

               (a)    ensure or procure that the deduction or withholding is
                      made and that it does not exceed the minimum legal
                      requirement therefor;

               (b)    pay, or procure the payment of, the full amount deducted
                      or withheld to the relevant Taxation or other authority in
                      accordance with the applicable law;

               (c)    (unless and to the extent the deduction or withholding
                      arises as a direct result of the negligence or wilful
                      default of the relevant Finance Party or the failure of
                      the relevant Finance Party to file any relevant tax form
                      or to provide any statements which have been reasonably
                      requested by the relevant tax authorities within a
                      reasonable time following a Change and which is within the
                      control of the relevant Finance Party to file or provide,
                      as the case may be) increase the payment in respect of
                      which the deduction or withholding is required so that the
                      net amount received by the payee (which expression when
                      used in this sub-clause 11.9.2 shall mean any Finance
                      Party) after the deduction or withholding (and after
                      taking account of any further deduction or withholding
                      which is required to be made as a consequence of the
                      increase) shall be equal to the amount which the payee
                      would have been entitled to receive in the absence of any
                      requirement to make any deduction or withholding; and

               (d)    promptly deliver or procure the delivery to the relative
                      payee of receipts evidencing each deduction or withholding
                      which has been made.

                                      -58-

       11.9.3  If the Facility Agent is obliged to make any deduction or
               withholding from any payment to any Bank (an "AGENCY PAYMENT")
               which represents an amount or amounts received by the Facility
               Agent from a Borrower under any Financing Document, that Borrower
               shall pay directly to that Bank such sum (an "AGENCY COMPENSATING
               SUM") as shall, after taking into account any deduction or
               withholding which that Borrower is obliged to make from the
               Agency Compensating Sum, enable that Bank to receive, on the due
               date for payment of the Agency Payment, an amount equal to the
               Agency Payment which that Bank would have received in the absence
               of any obligation to make any deduction or withholding.

       11.9.4  If any Bank determines, in its absolute discretion, that it has
               received, realised, utilised and retained a Tax benefit by reason
               of any deduction or withholding in respect of which a Borrower
               has made an increased payment or paid an Agency Compensating Sum
               under this Clause 11.9, that Bank shall, PROVIDED THAT the
               Finance Parties have received all amounts which are then due and
               payable by the obligors under any Financing Document, pay to that
               Borrower (to the extent that that Bank can do so without
               prejudicing the amount of the benefit or repayment and the right
               of that Bank to obtain any other benefit, relief or allowance
               which may be available to it) such amount, if any, as that Bank,
               in its absolute discretion shall determine, will leave that Bank
               in no worse position than it would have been in if the deduction
               or withholding had not been required, PROVIDED THAT:

               (a)    each Bank shall have an absolute discretion as to the time
                      at which and the order and manner in which it realises or
                      utilises any Tax benefit and shall not be obliged to
                      arrange its business or its Tax affairs in any particular
                      way in order to be eligible for any credit or refund or
                      similar benefit;

               (b)    no Bank shall be obliged to disclose any information
                      regarding its business, Tax affairs or Tax computations;

               (c)    if a Bank has made a payment to a Borrower pursuant to
                      this sub-clause 11.9.4 on account of any Tax benefit and
                      it subsequently transpires that that Bank did not receive
                      that Tax benefit, or received a lesser Tax benefit, that
                      Borrower shall, on demand, pay to that Bank such sum as
                      that Bank may determine as being necessary to restore its
                      after-tax position to that which it would have been had no
                      adjustment under this sub-clause 11.9.4 been made.

       11.9.5  No Bank shall be obliged to make any payment under sub-clause
               11.9.4 if, by doing so, it would contravene the terms of any
               applicable law or any notice, direction or requirement of any
               governmental or regulatory authority (whether or not having the
               force of law).

       11.9.6  If a Borrower is required to make an increased payment for the
               account of a Bank under sub-clause 11.9.2, then, without
               prejudice to that obligation and so long as such requirement
               exists and subject to the Parent Guarantor giving the Facility
               Agent acting reasonably and that Bank not less than 10 days'
               prior

               notice (which shall be irrevocable), the Borrowers may (a) prepay
               all, but not part, of that Bank's Participation in the Advances
               together with accrued interest on the amount prepaid and (b) pay
               to one or more accounts nominated by the Facility Agent amounts
               in the relevant currencies equal, in aggregate, to that Bank's
               actual and contingent liabilities under its Bank Indemnity and
               shall charge such accounts in favour of the Facility Agent on
               terms reasonably satisfactory to the Facility Agent. Any such
               prepayment shall be subject to Clause 24.1 (BREAKAGE COSTS
               INDEMNITY). On any such prepayment the Commitment of the relevant
               Bank shall be automatically cancelled.

12.    SECURITY

12.1   SECURITY DOCUMENTS

       The obligations and liabilities of the Borrowers to the Finance Parties
       under the Financing Documents shall be secured by the interests and
       rights granted in favour of the Security Trustee as trustee for itself,
       the Facility Agent, the Issuing Bank, the Overdraft Bank, the Lead
       Arranger and the Banks under the Security Documents.

12.2   INTEREST RATE PROTECTION AGREEMENTS

       12.2.1  All obligations and liabilities of a Borrower to any Bank or, as
               the case may be, the Overdraft Bank under or in connection with
               any Interest Rate Protection Agreement shall be treated, for all
               purposes (other than Clauses 11.7 (PARTIAL PAYMENTS) and 17.1
               (REDISTRIBUTION)), as obligations and liabilities incurred under
               this Agreement and, for the avoidance of doubt, a Borrower's
               obligations and liabilities under any Interest Rate Protection
               Agreement shall be secured obligations and liabilities under the
               Security Documents and for such purposes any reference in any
               Security Document to a Bank shall be deemed to include that Bank
               or, as the case may be, the Overdraft Bank as a party to the
               relevant Interest Rate Protection Agreements.

       12.2.2  In respect of an Interest Rate Protection Agreement,
               notwithstanding the terms of such Interest Rate Protection
               Agreement, the Bank that is a party thereto may only exercise its
               rights to terminate that Interest Rate Protection Agreement by
               reason of an event of default (howsoever described) if:

               (a)    such event of default relates to non-payment of any amount
                      under such Interest Rate Protection Agreement by the Group
                      Company that is a party thereto; or

               (b)    a resolution is passed, or a court order is made, which
                      would result in the bankruptcy, liquidation or dissolution
                      of such Group Company; or

               (c)    a Default Notice is served pursuant to Clause 15.2
                      (ACCELERATION, ETC).

12.3   RELEASE OF SECURITY ON DISPOSALS

       In respect of any Disposal made by a Group Company which falls within
       sub-clauses 14.3.2(a) to 14.3.2(h) of Clause 14.3 (NEGATIVE
       UNDERTAKINGS), the Security Trustee shall (and is authorised by the
       Finance Parties so to do) on the completion of that Disposal release, at
       the cost and expense of the Parent Guarantor, from the Security
       Documents,

       Disposal which falls within sub-clause 14.3.2(b) of Clause 14.3 (NEGATIVE
       UNDERTAKINGS), only if the Security Trustee is reasonably satisfied that
       it will receive security over the asset purchased with the Disposal
       Proceeds of the released asset equivalent to that which attached to the
       released asset immediately prior to its release from the Security
       Documents.

                      of Chartered Accountants in England and Wales to nominate
                      a firm of chartered accountants for that purpose. Such

               other period in relation to which the calculation falls to be
               made. Each determination of the Facility Agent under this Clause

               any manifest error.

               by or on behalf of any Borrower under or in connection with any

               Parent Guarantor cancel the Facilities and require the Borrowers
               immediately to repay each Loan together with accrued interest and
               all other sums payable under this Agreement, whereupon they shall

               Default Notice the Banks' obligations to each Borrower under this
               Agreement shall be terminated and the Commitment of each Bank
               shall be cancelled.

       15.2.2  Immediately upon the Facility Agent serving a Default Notice,
               each Borrower shall in respect of each Guarantee issued on its
               behalf:

               (a)    use its reasonable endeavours to procure the release of
                      the Issuing Bank or, as the case may be, the Overdraft
                      Bank, from the Guarantee; and

               (b)    without prejudice to sub-clause 15.2.2(a), pay to the
                      credit of such account as the Issuing Bank or, as the case
                      may be, the Overdraft Bank, shall stipulate an amount
                      equal to the Guaranteed Amount of that Guarantee and
                      charge such account in favour of the Issuing Bank or, as
                      the case may be, the Overdraft Bank, in such manner and on
                      such terms as the Issuing Bank or, as the case may be, the
                      Overdraft Bank, may stipulate.

       15.2.3  Immediately upon the Facility Agent serving a Default Notice,
               each outstanding FFE Contract shall be automatically terminated
               and closed out. Upon such termination and close-out, the
               Overdraft Bank shall determine in good faith the applicable
               closing gain or loss payable by or to it for the outstanding FFE
               Contracts, calculated by reference to the netting of the
               respective amounts in each currency which the Overdraft Bank is
               contracted to deliver and receive under all such FFE Contracts.
               Any amount payable to the Overdraft Bank or to any Borrower in
               respect of the FFE Contracts pursuant to this sub-clause 15.2.3

               Overdraft Bank shall:

               (a)    make demand on each overdraft made available under the
                      Optional Overdraft Facility; and

               (b)    terminate all other facilities or financial accommodation
                      made available by it under the Optional Overdraft Facility
                      (and which are not referred to in sub-clauses 15.2.2 and
                      15.2.3),

               whereupon any moneys owing to the Overdraft Bank shall be
               immediately due and payable and the Overdraft Bank may apply any
               credit balance on any account of any Charging Group Company with
               the Overdraft Bank against any liability owed to the Overdraft
               Bank by that Charging Group Company (to the extent that any such
               credit balance is freely available to be set off in this manner).

       15.2.5  If the Overdraft Bank makes a demand under any overdraft provided
               under the Optional Overdraft Facility, that demand shall not be a
               Default for the purposes of sub-clause 15.1.1 and the Security
               Trustee shall not take any steps to enforce

                                      -80-

               the Security Documents in respect of that demand if (a) that
               demand is satisfied in full within 15 Business Days of the date
               of that demand and (b) no other Default has occurred and is
               continuing during that period. For the avoidance of doubt, if any
               other Default has occurred, the Agents and the Banks may exercise
               all their rights under this Clause 15 and the Security Trustee
               may enforce the Security Documents, including in respect of the
               amount so demanded by the Overdraft Bank.

15.3   LOSS SHARING

       15.3.1  In this Clause 15.3:

               "OVERDRAFT OUTSTANDINGS" means the aggregate of:

               (a)    all amounts outstanding by way of overdraft under the
                      Optional Overdraft Facility (after deducting any credit
                      balance on any account of any Charging Group Company with
                      the Overdraft Bank which is freely available to be set off
                      by the Overdraft Bank against liabilities owed to the
                      Overdraft Bank by that Charging Group Company);

               (b)    the Guaranteed Amount of each Guarantee issued by the
                      Overdraft Bank;

               (c)    the liabilities of each Borrower to the Overdraft Bank
                      under sub-clause 15.2.3; and

               (d)    in relation to any other facilities or financial
                      accommodation provided under the Optional Overdraft
                      Facility, such other amount as the Overdraft Bank
                      determines fairly represents the aggregate exposure of the
                      Overdraft Bank in respect of that facility or
                      accommodation.

               "REVOLVING OUTSTANDINGS" means, in relation to a Bank, the
               Original Dollar Amount of (i) its Participations in the Revolving
               Advances and (ii) its Bank Indemnity, PROVIDED THAT in
               calculating the Revolving Outstandings of the Bank which is the
               Overdraft Bank, its Revolving Outstandings shall also include the
               Overdraft Outstandings.

               "TOTAL REVOLVING OUTSTANDINGS" means the aggregate of all
               Revolving Outstandings.

       15.3.2  The Facility Agent shall, within 4 Business Days of the service
               of a Default Notice:

               (a)    determine the adjusting payments required to be made
                      between the Banks to ensure that the Revolving
                      Outstandings of each Bank bears the same proportion to the
                      Total Revolving Outstandings as its Revolving Credit
                      Commitment bears to the Total Revolving Credit Commitments
                      (taking no account for these purposes of the last sentence
                      of sub-clause 15.2.1;

               (b)    provide to the Banks details of how such adjusting
                      payments were calculated; and

               (c)    request that the Banks make such adjusting payments
                      between themselves.

                                      -81-

<Page>


       15.3.3  Each Bank shall promptly make the adjusting payments requested of
               it by the Facility Agent under this Clause 15.3.

       15.3.4  Any amount paid by a Bank under this Clause 15.3 shall be deemed
               to be an immediately due and payable debt of the Borrowers to
               that Bank.

       15.3.5  Any amount received by a Bank under this Clause 15.3 shall be
               deemed to be a payment by the Borrowers of sums owed under this
               Agreement.

       15.3.6  If any future or contingent liability included in the calculation
               of Revolving Outstandings for any Bank for the purposes of Clause
               15.2.3 finally matures, or is settled, for less than the future
               or contingent amount provided for in that calculation, that Bank
               shall notify the Facility Agent. The Facility Agent shall
               determine the further adjusting payments required to be made by
               that Bank to put the Banks into the position they would have been
               in had the original adjusting payments been made on the basis of
               the actual as opposed to the future or contingent liability (but
               taking no account of the time cost of money) and shall request
               that Bank to make such further adjusting payments.

16.    SET-OFF

       Following the occurrence of a Default which remains outstanding (without
       prejudice to the Finance Parties rights at law) each Finance Party may
       set off any matured obligation owed by a Borrower under any Financing
       Document against any obligation (whether or not matured) owed by the
       relevant Finance Party to that Borrower, regardless of the place of
       payment, booking branch or currency of either obligation. If the
       obligations are in different currencies, the relevant Finance Party may
       convert either obligation at the relevant spot rate of exchange of the
       relevant Finance Party for the purpose of the set-off.

17.    PRO RATA SHARING

17.1   REDISTRIBUTION

       If any amount owing by a Borrower under this Agreement to a Bank (the
       "SHARING BANK") (other than an amount owing to the Overdraft Bank in its
       capacity as provider of the Optional Overdraft Facility) is discharged by
       voluntary or involuntary payment, set-off or any other manner other than
       through the Facility Agent in accordance with Clause 11 (PAYMENTS), then:

       17.1.1  the Sharing Bank shall immediately notify the Facility Agent of
               the amount discharged and the manner of its receipt or recovery;

       17.1.2  the Facility Agent shall determine whether the amount discharged
               is in excess of the amount which the Sharing Bank would have
               received had the amount discharged been received by the Facility
               Agent and distributed in accordance with Clause 11 (PAYMENTS);

       17.1.3  the Sharing Bank shall pay the Facility Agent an amount equal to
               that excess (the "EXCESS AMOUNT") within 5 Business Days of
               demand by the Facility Agent;

                                      -82-

<Page>


       17.1.4  the Facility Agent shall treat the Excess Amount as if it were a
               payment by a Borrower under Clause 11 (PAYMENTS) and shall pay
               the Excess Amount to the Banks (other than the Sharing Bank) in
               accordance with Clause 11.7 (PARTIAL PAYMENTS); and

       17.1.5  as between the relevant Borrower and the Sharing Bank the Excess
               Amount shall be treated as not having been received or recovered,
               and that Borrower shall owe the Sharing Bank an immediately
               payable debt equal to the Excess Amount.

17.2   LEGAL PROCEEDINGS

       Notwithstanding Clause 17.1 (REDISTRIBUTION), no Sharing Bank shall be
       obliged to share any Excess Amount which it receives or recovers pursuant
       to legal proceedings taken by it to recover any sums owing to it under
       this Agreement with any other Bank which has a legal right to, but does
       not, either join in such proceedings or commence and diligently pursue
       separate proceedings to enforce its rights, unless the proceedings
       instituted by the Sharing Bank are instituted by it without prior notice
       having been given to such Bank through the Facility Agent and an
       opportunity to such Bank to join in such proceedings.

17.3   REVERSAL OF REDISTRIBUTION

       If any Excess Amount subsequently has to be wholly or partly refunded to
       a Borrower by a Sharing Bank which has paid an amount equal to that
       Excess Amount to the Facility Agent under Clause 17.1 (REDISTRIBUTION),
       each Bank to which any part of that amount was distributed shall on
       request from the Sharing Bank repay to the Sharing Bank that Bank's
       proportionate share of the amount which has to be so refunded by the
       Sharing Bank.

17.4   INFORMATION

       Each Bank shall on request supply to the Facility Agent such information
       as the Facility Agent may from time to time request for the purpose of
       this Clause 17.

18.    THE FINANCE PARTIES

18.1   APPOINTMENT AND DUTIES

               to act). Any such instructions, and any action taken by the
               Facility Agent in accordance with those instructions, shall be
               binding upon all the Banks.

                      associated company of a Group Company, as freely in all
                      respects as if it had not been appointed to act as agent
                      and/or trustee for the Banks under this Agreement and
                      without regard to the effect on the Banks of acting in
                      such capacity; and

               (b)    subscribe for, hold, be beneficially entitled to or
                      dispose of shares or securities, or options or other
                      rights to and interests in shares or securities in any
                      Group Company or any associated company of a Group Company
                      (in each case, without liability to account).

       18.1.4  Each division of the Facility Agent (including, for so long as
               The Royal Bank of Scotland plc is the Facility Agent, the agency
               department of The Royal Bank of Scotland plc) shall be treated as
               a separate entity from any other division or department of the
               Facility Agent. If any of the Facility Agent's divisions or
               departments (including, in the case of The Royal Bank of Scotland
               plc, its agency department) should act for any Group Company in
               any capacity (whether as bankers or otherwise) in relation to any
               other matter, any information given by any Group Company to any
               such division or department may be treated as confidential and
               the Facility Agent shall, as between itself and the Banks, not be
               obliged to disclose the same to any Bank or any other person.

       18.1.5  The Issuing Bank acts solely as issuer of Guarantees under the
               Revolving Credit Facility and owes no fiduciary duties to any
               other Party in respect of the Financing Documents and the
               Guarantees.

       18.1.6  It is acknowledged that the role of the Lead Arranger is and has
               been confined solely to arranging the Facilities and that the
               Lead Arranger does not act as agent of any Bank and that in such
               capacity the Lead Arranger shall have no obligations and
               liabilities in relation to this Agreement.

18.2   PAYMENTS

       18.2.1  The Facility Agent shall promptly account to the Lending Office
               of each Bank for such Bank's due proportion of all sums received
               by the Facility Agent for such Bank's account, whether by way of
               repayment or prepayment of principal or payment of interest, fees
               or otherwise.

       18.2.2  The Facility Agent shall maintain a memorandum account showing
               the principal amount of each Advance outstanding under this
               Agreement and the amount of each Bank's Participation in each
               Advance.

18.3   DEFAULT

       The Facility Agent shall not be obliged to monitor or enquire as to
       whether or not a Default or Potential Default has occurred. The Facility
       Agent shall be entitled to assume that no Default or Potential Default
       has occurred unless it receives notice to the contrary from a Borrower or
       any Bank describing the Default or Potential Default and stating that

                                      -84-

<Page>


       such notice is a "Default Notice" or unless it is aware of a payment
       default under this Agreement, in which case it shall promptly notify each
       Bank, the Issuing Bank and the Overdraft Bank.

18.4   RELIANCE

       The Facility Agent may:

       18.4.1  rely on any communication or document believed by it to be
               genuine and correct and to have been communicated or signed by
               the person by whom it purports to be communicated or signed; and

       18.4.2  engage, pay for and rely on the advice of any professional
               advisers selected by it given in connection with the Financing
               Documents or any of the matters contemplated by the Financing
               Documents,

       and shall not be liable to any Party for any of the consequences of such
       reliance.

18.5   LEGAL PROCEEDINGS

       18.5.1  The Facility Agent shall not be obliged to take or commence any
               legal action or proceeding against a Borrower or any other person
               arising out of or in connection with the Financing Documents
               until it shall have been indemnified or secured to its
               satisfaction against all costs, claims and expenses (including
               any costs award which may be made against it as a result of any
               such legal action or proceeding not being successful) which it
               may expend or incur in such legal action or proceeding.

       18.5.2  The Facility Agent may refrain from doing anything which might in
               its opinion constitute a breach of any law or any duty of secrecy
               or confidentiality or be otherwise actionable at the suit of any
               person.

18.6   NO LIABILITY

       18.6.1  None of the Facility Agent or the Lead Arranger or any of its
               respective officers, employees or agents shall be liable for any
               action taken or not taken by it or any of them under or in
               connection with the Financing Documents unless directly caused by
               its or their gross negligence or wilful misconduct.

       18.6.2  Neither the Facility Agent nor the Lead Arranger shall be
               responsible for any statements, representations or warranties in
               the Financing Documents or for any information supplied or
               provided to any Bank or the Issuing Bank or the Overdraft Bank by
               the Facility Agent or the Lead Arranger in respect of a Borrower
               or any other person or for any other matter relating to the
               Financing Documents or for the execution, genuineness, validity,
               legality, enforceability or sufficiency of such documents or any
               other document referred to in the Financing Documents or for the
               recoverability of any Advance or any other sum to become due and
               payable under the Financing Documents.

18.7   CREDIT DECISIONS

       18.7.1  Each Bank, the Issuing Bank and the Overdraft Bank:

                                      -85-

<Page>


               (a)    acknowledges that it has, independently and without
                      reliance on the Facility Agent or the Lead Arranger, made
                      its own analysis of the transaction contemplated by, and
                      reached its own decision to enter into, this Agreement and
                      made its own investigation of the financial condition and
                      affairs and its own appraisal of the creditworthiness of
                      the Borrowers and any surety for the Borrowers'
                      obligations; and

               (b)    shall continue to make its own independent appraisal of
                      the creditworthiness of the Borrowers and any surety for
                      the Borrowers' obligations.

       18.7.2  Each Bank, the Issuing Bank and the Overdraft Bank shall,
               independently and without reliance on the Facility Agent or the
               Lead Arranger, make its own decision to take or not take action
               under the Financing Documents.

18.8   INFORMATION

       18.8.1  The Facility Agent shall provide the Banks, the Issuing Bank and
               the Overdraft Bank with all information and copies of all notices
               which are given to it and which by the terms of this Agreement
               are to be provided or given to the Banks, the Issuing Bank and
               the Overdraft Bank, as the case may be.

       18.8.2  Except as provided in this Agreement, the Facility Agent shall
               not be under any duty or obligation:

               (a)    either initially or on a continuing basis, to provide any
                      Bank, the Issuing Bank or the Overdraft Bank with any
                      credit information or other information with respect to
                      the financial condition of a Borrower or which is
                      otherwise relevant to the Facilities; or

               (b)    to request or obtain any certificate, document or
                      information from a Borrower unless specifically requested
                      to do so by a Bank, the Issuing Bank or in accordance with
                      this Agreement.

18.9   RELATIONSHIP WITH BANKS

       18.9.1  In performing its functions and duties under this Agreement, the

               to be acting as trustee for any Bank. The Facility Agent shall
               not assume or be deemed to have assumed any obligation as agent

               Borrower.

       18.9.2  Neither the Facility Agent nor any Bank shall be under any
               liability or responsibility of any kind to a Borrower, the
               Issuing Bank, the Overdraft Bank or any other Bank arising out of
               or in relation to any failure or delay in performance or breach
               by a Borrower, the Issuing Bank, the Overdraft Bank or any other
               Bank of any of its or their respective obligations under the
               Financing Documents.

18.10  FACILITY AGENT'S POSITION

       18.10.1 With respect to its own Participation in the Facilities, the
               Facility Agent shall have the same rights and powers under and in
               respect of the Financing Documents as any other Bank and may
               exercise those rights and powers as though it were not also
               acting as agent and/or trustee under this Agreement. The Facility
               Agent may, without liability to account, accept deposits from,
               lend money to and generally engage in any kind of banking,
               finance, advisory, trust or other business with or for a Borrower
               as if it were not the agent or the trustee for other persons
               under any Financing Documents.

       18.10.2 The Facility Agent may retain for its own use and benefit (and
               shall not be liable to account to any Bank, the Issuing Bank or
               the Overdraft Bank for all or any part of) any sums received by
               it by way of agency or management or arrangement fees or by way
               of reimbursement of expenses incurred by it.

18.11  INDEMNITY

       Each Bank shall immediately on demand indemnify the Facility Agent (to
       the extent not reimbursed by the Borrowers) rateably according to that
       Bank's Participation in the Facilities (or, if no Term Advance shall then
       be outstanding, its Commitment) from and against all liabilities, losses
       and expenses of any kind or nature whatsoever (except in respect of any
       agency, management or other fee due to the Facility Agent) which may be
       incurred by the Facility Agent in its capacity as agent or trustee under
       this Agreement or in any way relating to or arising out of the Financing
       Documents or any action taken or omitted by the Facility Agent in
       enforcing or preserving the rights of the Finance Parties under the
       Financing Documents, PROVIDED THAT no Bank shall be liable for any
       portion of such liabilities, losses or expenses resulting from the
       Facility Agent's gross negligence or wilful misconduct.

18.12  RESIGNATION

       18.12.1 The Facility Agent may resign by giving at least 60 days' notice
               to the Parent Guarantor and each Bank. Upon receipt of a notice
               of resignation the Parent Guarantor and the Majority Banks may
               select any bank or other financial institution as successor
               Facility Agent.

       18.12.2 If no bank or other financial institution selected by the Parent
               Guarantor and the Majority Banks shall have accepted such
               appointment within 20 days after the resigning Facility Agent has
               given a notice of resignation then the Majority Banks may, after
               consultation with the Parent Guarantor, appoint any bank or other
               financial institution as successor Facility Agent.

       18.12.3 If no bank or other financial institution selected by the
               Majority Banks shall have accepted such appointment within 40
               days after the resigning Facility Agent has given a notice of
               resignation then the resigning Facility Agent may, after
               consultation with the Parent Guarantor, appoint any bank or other
               financial institution with an office in London as successor
               Facility Agent.

       18.12.4 The resignation of the Facility Agent and the appointment of any
               successor Facility Agent shall both become effective only upon
               the successor Facility

                                      -87-

<Page>


               Agent notifying the resigning Facility Agent, the Parent
               Guarantor and each Bank that it accepts its appointment. On such
               notification:

               (a)    the resigning Facility Agent shall be discharged from its
                      obligations and duties as Facility Agent under the
                      Financing Documents but it shall continue to be able to
                      rely on the provisions of this Clause 18 in respect of all
                      matters relating to the period of its appointment; and

               (b)    the successor Facility Agent shall assume the role of
                      Facility Agent and shall have all the rights, powers,
                      discretions and duties which the Facility Agent has under
                      the Financing Documents.

       18.12.5 The resigning Facility Agent shall make available to the
               successor Facility Agent all records and documents held by it as
               Facility Agent and shall co-operate with the successor Facility
               Agent to ensure an orderly transition.

18.13  CHANGE OF OFFICE

       The Facility Agent may at any time in its sole discretion by notice to
       the Parent Guarantor and each Bank designate a different office in the
       United Kingdom from which its duties as the Facility Agent will be
       performed.

18.14  DISTRIBUTION OF PROCEEDS OF ENFORCEMENT

       18.14.1 In this Clause 18.14:

               "BANK OUTSTANDINGS" means, in respect of a Bank, the aggregate
               of:

               (a)    all amounts actually and contingently due to it under this
                      Agreement (including, in the case of the Bank which is the
                      Overdraft Bank, the Overdraft Outstandings); and

               (b)    all amounts actually and contingently due to it in respect
                      of the Interest Rate Protection Agreements.

               "OVERDRAFT OUTSTANDINGS" has the meaning given to that term in
               sub-clause 15.1.1 of Clause 15.1 (DEFAULT).

               "TOTAL OUTSTANDINGS" means the aggregate amount of all Bank
               Outstandings.

       18.14.2 On receiving proceeds under the Intercreditor Agreement, the
               Facility Agent shall be entitled to deduct from the proceeds of
               such enforcement its costs, charges and expenses incurred in
               connection with such enforcement together with an amount equal to
               all sums due to the Facility Agent under this Agreement before
               distributing to each Bank an amount equal to the remaining
               proceeds multiplied by:

                         Bank Outstandings of such Bank
                        --------------------------------
                               Total Outstandings

               where Bank Outstandings, the Overdraft Outstandings and the Total
               Outstandings are all calculated as at the date of distribution
               PROVIDED THAT if a Bank owes moneys under this Agreement to the
               Issuing Bank, all distributions

                                      -88-

<Page>


               which would otherwise be made to that Bank shall be made to the
               Issuing Bank to be applied in discharge of such moneys until the
               same have been discharged in full.

       18.14.3 Where any part of any Bank Outstandings is denominated in a
               currency other than Dollars, any calculation for the purposes of
               this sub-clause 18.14 shall be made on the basis of the Dollar
               Equivalent of that part calculated as at the date of
               distribution. However, an actual distribution may, in the
               Facility Agent's discretion, be made in the currencies of the
               Bank Outstandings and for this purpose the Facility Agent is
               authorised to convert any proceeds of enforcement (including the
               proceeds of any previous conversion under this Clause) from their
               existing currency into any other currency at such rate of
               exchange and at such time as the Facility Agent thinks fit.

       18.14.4 The Facility Agent shall notify each Bank of any proposed
               distribution and the proposed date of distribution and each Bank
               shall provide to the Facility Agent a calculation of what is due
               to it in respect of the sums referred to in sub-clause 18.14.1.
               The Facility Agent shall send copies of all such calculations to
               each Bank and shall make the distributions on the basis of such
               calculations.

       18.14.5 If any future or contingent liability included in the calculation
               of Bank Outstandings or Overdraft Outstandings finally matures,
               or is settled, for less than the future or contingent amount
               provided for in that calculation, the relevant Bank shall notify
               the Facility Agent of that fact and such adjustment shall be made
               by payment by that Bank to the Facility Agent for distribution
               amongst the Banks as may be necessary to put the Banks into the
               position they would have been in (but taking no account of the
               time cost of money) had the original distribution been made on
               the basis of the actual as opposed to the future or contingent
               liability.

       18.14.6 The Facility Agent may, at its discretion, accumulate proceeds of
               enforcement in an interest bearing account in its own name until
               there is a minimum of US$500,000 to distribute under sub-clause
               18.14.2.

18.15  ISSUING BANK AND OVERDRAFT BANK

       18.15.1 The Issuing Bank or, as the case may be, the Overdraft Bank may,
               with the prior consent of the Parent Guarantor and the Facility
               Agent be replaced as Issuing Bank or, as the case may be, the
               Overdraft Bank by another Bank.

       18.15.2 Any replacement of the Issuing Bank or, as the case may be, the
               Overdraft Bank shall take effect only on the beneficiaries under
               all outstanding Guarantees, if any, agreeing that the Bank that
               is to replace the existing Issuing Bank or, as the case may be,
               the existing Overdraft Bank may be substituted in place of the
               existing Issuing Bank or, as the case may be, the existing
               Overdraft Bank as the obligor under all such Guarantees.

19.    FEES AND EXPENSES

19.1   EXPENSES

       The Parent Guarantor shall on demand pay all expenses incurred (including
       legal, valuation and accounting fees but, in relation to sub-clauses
       19.1.1, 19.1.2 and 19.1.3, only to the extent the same are reasonable in
       amount), and any VAT on those expenses:

               the negotiation, preparation and execution of the Financing

       All stamp, documentary, registration or other like duties or Taxes,
       including any penalties, additions, fines, surcharges or interest
       relating to those duties and Taxes, which are imposed or chargeable on or
       in connection with any Financing Document shall be paid by the Parent
       Guarantor. The Facility Agent shall be entitled but not obliged to pay
       any such duties or Taxes (whether or not they are its primary
       responsibility). If the Facility Agent does so the Parent Guarantor shall
       on demand indemnify the Facility Agent against those duties and Taxes and
       against any costs and expenses incurred by the Facility Agent in
       discharging them.

19.5   VAT

       19.5.1  All payments made by a Borrower under the Financing Documents are
               calculated without regard to VAT. If any such payment constitutes
               the whole or any part of the consideration for a taxable or
               deemed taxable supply (whether that supply is taxable pursuant to
               the exercise of an option or otherwise) by a Finance Party, the
               amount of that payment shall be increased by an amount equal to
               the amount of VAT which is chargeable in respect of the taxable
               supply in question.

       19.5.2  No payment or other consideration to be made or furnished to a
               Borrower by a Finance Party pursuant to or in connection with any
               Financing Document or any transaction or document contemplated in
               any Financing Document may be increased or added to by reference
               to (or as a result of any increase in the rate of) any VAT which
               shall be or may become chargeable in respect of any taxable
               supply.

19.6   INDEMNITY PAYMENTS

       Where in any Financing Document a Borrower has an obligation to indemnify
       or reimburse a Finance Party in respect of any loss or payment, the
       calculation of the amount payable by way of indemnity or reimbursement
       shall take account of the likely Tax treatment in the hands of the
       relevant Finance Party (as conclusively determined by the relevant party)
       of the amount payable by way of indemnity or reimbursement and of the
       loss or payment in respect of which that amount is payable.

               law; and

       20.4.3  may be waived only in writing and specifically.

       result the Bank of England recognises more than one currency or currency

<Page>


               (c)    each of the Parties and the Bank Transferee shall acquire
                      the same rights and assume the same obligations among
                      themselves as they would have acquired and assumed had the
                      Bank Transferee been a party under this Agreement as a
                      Bank with the rights and/or the obligations acquired or
                      assumed by it as a result of the transfer; and

               (d)    a proportion of the Existing Bank's rights under the

               completed Transfer Certificate on its behalf PROVIDED THAT such

               of the Parent Guarantor (such consent not to be unreasonably

               transfer or assignment made in consultation with the Parent
               Guarantor as part of the primary syndication of the Facilities.

       23.5.2  An assignment or transfer shall be in respect of a Commitment of

               which are not banks exceeding 10.

23.6   CONSEQUENCES OF TRANSFER

       The Borrowers shall be under no obligation to pay any greater amount
       under this Agreement following an assignment or transfer by a Bank of any
       of its rights or obligations pursuant to this Clause 23.6 if, in the
       circumstances existing at the time of such assignment or transfer, such
       greater amount would not have been payable but for the assignment or
       transfer.

23.7   DISCLOSURE OF INFORMATION

       Each Finance Party may not disclose except to each other, to their
       professional advisers and, subject to any such person entering into a
       confidentiality undertaking in favour of the Parent Guarantor, to any
       person with whom they are proposing to enter, or have entered into, any
       kind of assignment, transfer, novation, participation or other agreement
       in relation to this Agreement, any information which that Finance Party
       has acquired

                                      -95-

       under or in connection with any Financing Document, PROVIDED THAT each
       Finance Party may disclose to any person any information that such
       Finance Party has acquired under or in connection with any Financing
       Document which is already in the public domain or which it is required by
       law or any regulatory authority to disclose.

               Notice (except as a result of the failure of that Bank to comply
               with its obligations under this Agreement);

       24.2.1  Any payment made to or for the account of or received by any
               Finance Party in respect of any moneys or liabilities due,
               arising or incurred by a Borrower to any Finance Party in a
               currency (the "CURRENCY OF PAYMENT") other than the currency in
               which the payment should have been made under this Agreement (the
               "CURRENCY OF OBLIGATION") in whatever circumstances (including as
               a result of a judgment against a Borrower) and for whatever
               reason shall constitute a discharge to that Borrower only to the
               extent of the Currency of Obligation amount which that Finance
               Party is able on the date of receipt of such payment (or if such
               date of receipt is not a Business Day, on the next succeeding
               Business Day) to purchase with the Currency of Payment amount at
               its spot rate of exchange (as conclusively determined by that
               Finance Party) in the London foreign exchange market.

       24.2.2  If the amount of the Currency of Obligation which that Finance
               Party is so able to purchase falls short of the amount originally
               due to that Finance Party under this Agreement, then the relevant
               Borrower shall immediately on demand indemnify that Finance Party
               against any loss or damage arising as a result of

                                      -97-

               that shortfall by paying to that Finance Party that amount in the
               Currency of Obligation certified by that Finance Party as
               necessary so to indemnify it.

24.3  GENERAL

       24.3.1  Each indemnity in this Clause 24 shall constitute a separate and
               independent obligation from the other obligations contained in
               this Agreement, shall give rise to a separate and independent
               cause of action, shall apply irrespective of any indulgence
               granted from time to time and shall continue in full force and
               effect notwithstanding any judgment or order for a liquidated sum

       24.3.2  The certificate of the relevant Finance Party as to the amount of
               any loss or damage sustained or incurred by it shall be
               conclusive and binding on the Borrowers except for any manifest
               error.

       25.2.2  Each Borrower:

               (a)    waives any objections which it may have to the English

       judgment or other notice of legal process shall be sufficiently served on
       each Overseas Borrower if delivered to that agent at its address for the
       time being. No Overseas Borrower shall revoke the authority of that
       agent. If for any reason that agent no longer serves as agent of each
       Overseas Borrower

                                   SCHEDULE 5

                               MANDATORY COST RATE

The Mandatory Cost Rate is an addition to the interest rate on an Advance to
compensate the Banks for the cost attributable to an Advance resulting from the
imposition from time to time under or pursuant to the Bank of England Act 1998
(the "BANK OF ENGLAND ACT") and/or by the Bank of England and/or the Financial
Services Authority (the "FSA") (or other United Kingdom governmental authorities
or agencies) of a requirement to place non-interest-bearing or Special Deposits
(whether interest bearing or not) with the Bank of England and/or pay fees to
the FSA calculated by reference to liabilities used to fund the Advance.

The Mandatory Cost Rate shall be the rate determined by the Facility Agent to be
equal to the arithmetic mean (rounded upward, if necessary, to 4 decimal places)
of the respective rates notified by each Reference Bank to the Facility Agent as
the rate resulting from the application (as appropriate) of the following
formulae:

       in relation to an Advance denominated in Sterling: XL + S(L - D)+F X 0.01
                                                          ----------------------
                                                               100 - (X + S)

        in relation to an Advance denominated in
        a currency other than Sterling:                   F X 0.01
                                                          --------
                                                             300

where on the day of application of a formula:

X      is the percentage of Eligible Liabilities (in excess of any stated
       minimum) by reference to which that Reference Bank is required under or
       pursuant to the Bank of England Act to maintain cash ratio deposits with
       the Bank of England;

L      is LIBOR for the relevant Advance for the relevant period;

F      is the rate of charge payable by that Reference Bank to the FSA pursuant
       to paragraph 2.02 or 2.03, as the case may be, of the Fees Regulations
       (but where, for this purpose, the figures at paragraphs 2.02b and 2.03b
       of the Fees Regulations shall be deemed to be zero) and expressed in
       pounds per (pound)1 million of the Fee Base of that Reference Bank;

S      is the level of interest bearing Special Deposits, expressed as a
       percentage of Eligible Liabilities, which that Reference Bank is required
       to maintain by the Bank of England (or other United Kingdom governmental
       authorities or agencies); and

D      is the percentage rate per annum payable by the Bank of England to that
       Reference Bank on Special Deposits.

(X, L, S and D shall be expressed in the formula as numbers and not as
percentages, e.g. if X = 0.15% and L = 7%, XL will be calculated as 0.15 x 7 and
not as 0.15% x 7%. A negative result obtained from subtracting D from L shall be
counted as zero.)

If any Reference Bank fails to notify any such rate to the Facility Agent, the
Mandatory Cost Rate shall be determined on the basis of the rate(s) notified to
the Facility Agent by the remaining Reference Bank(s).

                                     -111-

<Page>


The Mandatory Cost Rate attributable to an Advance or other sum for any period
shall be calculated at or about 11.00 a.m. on the first day of that period for
the duration of that period.

The determination of the Mandatory Cost Rate in relation to any period shall, in
the absence of manifest error, be conclusive and binding on the Parties.

If there is any change in circumstance (including the imposition of alternative
or additional requirements) which in the reasonable opinion of the Facility
Agent renders or will render either of the above formulae (or any element of the
formulae, or any defined term used in the formulae) inappropriate or
inapplicable, the Facility Agent (following consultation with the Borrowers and
the Majority Banks) shall be entitled to vary the same by giving notice to the
Parties. Any such variation shall, in the absence of manifest error, be
conclusive and binding on the Parties and shall apply from the date specified in
such notice.

For the purposes of this Schedule:

       "ELIGIBLE LIABILITIES" and "SPECIAL DEPOSITS" have the meanings given to
       those terms under or pursuant to the Bank of England Act or by the Bank
       of England (as may be appropriate), on the day of the application of the
       formula.

       "FEE BASE" has the meaning given to that term for the purposes of, and
       shall be calculated in accordance with, the Fees Regulations.

       "FEES REGULATIONS" means the Banking Supervision (Fees) Regulations 2001
       or such other law or regulation as may be in force from time to time in
       respect of the payment of fees for banking supervision.

MEMORANDUM


This Memorandum is given in connection with the proposed arrangements whereby
the Company will give financial assistance for the acquisition of [its own]
shares, particulars of which are given in the statutory declaration made by the
directors this day pursuant to section 155(6) of the Companies Act 1985 (the
"ACT")

1.     As at the close of business on * [the latest practicable date before the
       memorandum is signed] the aggregate of the Company's assets as stated in
       its accounting records exceeded the aggregate of its liabilities as so
       stated.

2.     Based on the Company's knowledge of events since that date and of the
       likely course of the Company's business [as described in the accompanying
       paper] and having received advice from its financial advisers, the
       Company has formed the opinion that to the best of its knowledge and
       belief the aggregate of the Company's assets will exceed the aggregate of
       its liabilities immediately before the proposed financial assistance is
       given and

       EITHER  that the giving of such financial assistance will not reduce the
               net assets of the Company.

       OR      that the amount by which the giving of such financial assistance
               will reduce the net assets of the Company will not exceed the
               distributable profits of the Company as determined on the basis
               of its [last annual][interim] accounts made up to * (and after
               taking account of distributions since that date).
