     The Banks, upon the terms and subject to the conditions hereof, grant to
     the Account Party a dual currency letter of credit facility in an aggregate
     amount of (pound)380,000,000.

2.2  Purpose and Application
     The Facility is intended to support Funds at Lloyd's, and, accordingly, the
     Account Party shall apply all Letters of Credit issued hereunder in or
     towards satisfaction of such purpose and none of the Finance Parties shall
     be obliged to concern themselves with such application.

     listed in Schedule 3 (Conditions Precedent) and that each is, in form and
     substance, satisfactory to the Agent.

2.4  Several Obligations
     The obligations of each Bank are several and the failure by a Bank to
     perform its obligations hereunder and/or under any Letter of Credit issued
     hereunder shall not affect the obligations of either Obligor towards any
     other party hereto nor shall any other party be liable for the failure by
     such Bank to perform its obligations hereunder and/or under such Letter of
     Credit.

2.5  Several Rights
     The rights of each Finance Party are several and any debt arising hereunder
     at any time from an Obligor to any Finance Party shall be a separate and
     independent debt. Each such party shall be entitled to protect and enforce
     its individual rights arising out of this Agreement independently of any
     other party (so that it shall not be necessary for any party hereto to be
     joined as an additional party in any proceedings for this purpose).

     On and with effect from the Effective Date, all outstanding Original
     Letters of Credit shall be cancelled and replaced by the Letters of Credit
     issued after the Commencement Date.

            designate, by the date which falls three weeks prior to 30 September
            in that year, an Approved Credit Institution (the "Substitute Bank")
            which is willing to assume all of the rights and obligations of the
            Declining Bank in respect of its participation in the relevant
            Letter of Credit (the "Old Letter of Credit").

            year, transfer its rights and obligations hereunder to the
            Substitute Bank in accordance with the provisions of Clause 27.5
            (Transfers by Banks).

            extension of the Old Letter of Credit in any year (the "Extending
            Banks") shall, together with the Substitute Bank, issue, with effect
            from 30 September in that year, and participate in, a new Letter of
            Credit (the "New Letter of Credit") which shall:

                 Date specified in the Notice of Extension.

                 Old Letter of Credit from the Funds at Lloyd's of the relevant
                 Applicant,

            (b)  subject to the provisions of Clause 4.8 (Extension Conditions
                 Precedent), the Extending Banks shall issue, with effect from
                 30 September in that year, and participate in, a new Letter of
                 Credit (the "Reduced Letter of Credit") which shall:

                 (i)   replace their participation in the Old Letter of Credit;

                 (ii)  be in an amount equal to the Old Letter of Credit less
                       the amount of the Declining Bank's participation therein;

                 (iii) have a Termination Date which corresponds with the
                       Termination Date specified in the Notice of Extension;
                       and

            (c)  the Declining Bank shall issue, with effect from 30 September
                 in that year, and participate in, a separate Letter of Credit
                 (a "Bilateral Letter of Credit") which shall:

                 (i)   replace its participation in the Old Letter of Credit;

                 (ii)  be in an amount equal to the Declining Bank's
                       participation in the Old Letter of Credit; and

                 (iii) have a Termination Date which is the same as the
                       Termination Date of the Old Letter of Credit (as the same
                       may have been extended from time to time with the
                       agreement of the Declining Bank).

               provisions of the relevant Letter of Credit, the Banks shall not
               be obliged to agree to any extension requested if the Account
               Party fails to comply with its obligations under Clause 4
               (Extension of Letters of Credit) or if any of the events
               specified in sub-clause 4.8.1 above occurs.

        Lloyd's and subject to each Bank's Outstandings under the Letters of

     obligation, indemnify (on demand by the Agent) each Bank against:

     8.1.1   any sum paid or due and payable by such Bank in accordance with the
             terms of any Letter of Credit requested by the Account Party; and

             connection with such Letter of Credit), claims, losses and expenses
             which such Bank may at any time properly incur or sustain in
             connection with any Letter of Credit.

8.2  Preservation of Rights
     Neither the obligations of the Account Party set out in this Clause 8 nor
     the rights, powers and remedies conferred on any Bank by this Agreement or
     by law shall be discharged, impaired or otherwise affected by:

     8.2.1   the winding-up, dissolution, administration or re-organisation of
             any Bank or any other person or any change in its status, function,
             control or ownership;

     8.2.2   any of the obligations of any Bank or any other person hereunder or
             under any Letter of Credit or under any other security taken in
             respect of the Account Party's obligations hereunder or otherwise
             in connection with any Letter of Credit being or becoming illegal,
             invalid, unenforceable or ineffective in any respect;

     8.2.3   time or other indulgence being granted or agreed to be granted to
             any Bank or any other person in respect of its obligations
             hereunder or under or in connection with any Letter of Credit or
             under any such other security;

     8.2.4   any amendment to, or any variation, waiver or release of, any
             obligation of any Bank or any other person under any Letter of
             Credit or this Agreement; or

     8.2.5   any other act, event or omission which, but for this Clause 8,
             might operate to discharge, impair or otherwise affect any of the
             obligations of the Account Party

                                      -26-



          set out in this Clause 8 or any of the rights, powers or remedies
          conferred upon any Bank by this Agreement or by law.

     The obligations of the Account Party set out in this Clause 8 shall be in
     addition to and independent of every other security which any Bank may at
     any time hold in respect of the Account Party's obligations hereunder.

8.3  Settlement Conditional
     Any settlement or discharge between the Account Party and a Bank shall be
     conditional upon no security or payment to such Bank by the Account Party
     or any other person on behalf of the Account Party, being avoided or
     reduced by virtue of any laws relating to bankruptcy, insolvency,
     liquidation or similar laws of general application and, if any such
     security or payment is so avoided or reduced, such Bank shall be entitled
     to recover the value or amount of such security or payment from the Account
     Party subsequently as if such settlement or discharge had not occurred.

8.4  Right to make Payments under Letters of Credit
     Each Bank shall be entitled to make any payment in accordance with the
     terms of the relevant Letter of Credit without any reference to or further
     authority from the Account Party or any other investigation or enquiry. The
     Account Party irrevocably authorises each Bank to comply with any demand
     under a Letter of Credit which is valid on its face.

8.5  Revaluation of Outstandings
     On each L/C Valuation Date, the Agent shall calculate the amount of the
     Outstandings (having regard to changes in the Sterling Amounts of the
     Letters of Credit which may arise as a result of currency fluctuations),
     and the Agent shall notify the Account Party of the amount, if any (the
     "Excess Amount"), by which the Outstandings exceed 105 per cent. of the
     aggregate Commitments of the Banks on such date, and the Account Party
     shall secure such Excess Amount by providing Cash Collateral in an amount
     not less than the Excess Amount, provided that if the Account Party
     provides Cash Collateral as aforesaid and, on any succeeding L/C Valuation
     Date, the Excess Amount as determined on such date (the "New Excess
     Amount") is:

     8.5.1   less than the amount of the Cash Collateral provided at such time,
             the Agent shall deliver to the Account Party an amount equal to the
             difference between the amount of such Cash Collateral and the New
             Excess Amount; or

     8.5.2   greater than the amount of Cash Collateral provided at such time,
             the Account Party shall deliver to the Agent an amount equal to the
             amount by which the New Excess Amount exceeds the amount of such
             Cash Collateral.

9.   CANCELLATION and COLLATERALISATION

9.1  Cancellation/Cash Collateralisation of Letters of Credit

     Letter of Credit (whereupon it shall do so).

              be increased pursuant to Clause 10.1 (Tax Gross-up); or

       9.3.2  any Bank claims indemnification from the Account Party under
              Clause 10.2 (Tax Indemnity) or Clause 12.1 (Increased Costs),

       the Account Party may, whilst such circumstance continues, give the Agent

       its intention to cancel, and/or provide Cash Collateral in respect of the
       Commitment of such Bank.

9.4    Removal of a Bank

       reduction of the amount of such Letter of Credit in an amount equal to
       such Bank's L/C Proportion) or that Cash Collateral be provided in an
       amount equal to such Bank's L/C Proportion of such Letter of Credit.

9.5    No Further Availability
       A Bank for whose account a repayment is to be made under Clause 9.3
       (Notice of Removal of a Bank) shall not be obliged to participate in the
       making of any Letter of Credit on or after the date upon which the Agent
       receives the Account Party's notice of its intention to procure the
       repayment of such Bank's share of the Outstandings, and such Bank's
       Available Commitment shall be reduced to zero.

9.6    No Other Repayments or Cancellation
       The Account Party shall not repay or cancel all or any part of the
       Outstandings except at the times and in the manner expressly provided for
       in this Agreement.

10.    TAXES

10.1   Tax Gross-up
       All payments to be made by an Obligor to any Finance Party hereunder
       shall be made free and clear of and without deduction for or on account
       of tax unless such Obligor is required to make such a payment subject to
       the deduction or withholding of tax, in which case the sum payable by
       such Obligor (in respect of which such deduction or withholding is
       required to be made) shall be increased to the extent necessary to ensure
       that such Finance Party receives a sum net of any deduction or
       withholding equal to the sum which it would have received had no such
       deduction or withholding been made or required to be made.

                                      -28-



10.2   Tax Indemnity
       Without prejudice to Clause 10.1 (Tax Gross-up), if any Finance Party is
       required to make any payment of or on account of tax on or in relation to
       any sum received or receivable hereunder (including any sum deemed for
       purposes of tax to be received or receivable by such Finance Party
       whether or not actually received or receivable) or if any liability in
       respect of any such payment is asserted, imposed, levied or assessed
       against any Finance Party, the Account Party shall, upon demand of the
       Agent, promptly indemnify the Finance Party which suffers a loss or
       liability as a result against such payment or liability, together with
       any interest, penalties, costs and expenses payable or incurred in
       connection therewith, provided that this Clause 10.2 shall not apply to:

       10.2.1  any tax imposed on and calculated by reference to the net income
               actually received or receivable by such Finance Party by the
               jurisdiction in which such Finance Party is incorporated; or

       10.2.2  any tax imposed on and calculated by reference to the net income
               of the Facility Office of such Finance Party actually received or
               receivable by such Finance Party by the jurisdiction in which its
               Facility Office is located.

10.3   Claims by Banks
       A Bank intending to make a claim pursuant to Clause 10.2 (Tax Indemnity)
       shall notify the Agent of the event giving rise to the claim, whereupon
       the Agent shall notify the Account Party thereof.

11.    TAX RECEIPTS

11.1   Notification of Requirement to Deduct Tax
       If, at any time, an Obligor is required by law to make any deduction or
       withholding from any sum payable by it hereunder (or if thereafter there
       is any change in the rates at which or the manner in which such
       deductions or withholdings are calculated), such Obligor shall promptly,
       upon becoming aware of the same, notify the Agent.

11.2   Evidence of Payment of Tax
       If an Obligor makes any payment hereunder in respect of which it is
       required to make any deduction or withholding, it shall pay the full
       amount required to be deducted or withheld to the relevant taxation or
       other authority within the time allowed for such payment under applicable
       law and shall deliver to the Agent for each Bank, within thirty days
       after it has made such payment to the applicable authority, an original
       receipt (or a certified copy thereof) issued by such authority evidencing
       the payment to such authority of all amounts so required to be deducted
       or withheld in respect of that Bank's share of such payment.

11.3   Tax Credit Payment
       If an additional payment is made under Clause 10 (Taxes) by an Obligor
       for the benefit of any Finance Party and such Finance Party, in its sole
       discretion, determines that it has obtained (and has derived full use and
       benefit from) a credit against, a relief or remission for, or repayment
       of, any tax, then, if and to the extent that such Finance Party, in its
       sole opinion, determines that:

                                      -29-



       11.3.1  such credit, relief, remission or repayment is in respect of or
               calculated with reference to the additional payment made pursuant
               to Clause 10 (Taxes); and

       11.3.2  its tax affairs for its tax year in respect of which such credit,
               relief, remission or repayment was obtained have been finally
               settled,

       such Finance Party shall, to the extent that it can do so without
       prejudice to the retention of the amount of such credit, relief,
       remission or repayment, pay to such Obligor such amount as such Finance
       Party shall, in its sole opinion, determine to be the amount which will
       leave such Finance Party (after such payment) in no worse after-tax
       position than it would have been in had the additional payment in
       question not been required to be made by such Obligor.

11.4   Tax Credit Clawback
       If any Finance Party makes any payment to an Obligor pursuant to Clause
       11.3 (Tax Credit Payment) and such Finance Party subsequently determines,
       in its sole opinion, that the credit, relief, remission or repayment in
       respect of which such payment was made was not available or has been
       withdrawn or that it was unable to use such credit, relief, remission or
       repayment in full, the Obligor shall reimburse such Finance Party such
       amount as such Finance Party determines, in its sole opinion, is
       necessary to place it in the same after-tax position as it would have
       been in if such credit, relief, remission or repayment had been obtained
       and fully used and retained by such Finance Party.

11.5   Tax and Other Affairs
       No provision of this Agreement shall interfere with the right of any
       Finance Party to arrange its tax or any other affairs in whatever manner
       it thinks fit, oblige any Finance Party to claim any credit, relief,
       remission or repayment in respect of any payment under Clause 10.1 (Tax
       Gross-up) in priority to any other credit, relief, remission or repayment
       available to it nor oblige any Finance Party to disclose any information
       relating to its tax or other affairs or any computations in respect
       thereof.

12.    INCREASED COSTS

12.1   Increased Costs

       If, by reason of (a) any change in law or in its interpretation or
       administration and/or (b) compliance with any request or requirement
       relating to the maintenance of capital or any other request from or
       requirement of any central bank or other fiscal, monetary or other
       authority (being a request or requirement with which banks are accustomed
       to comply) and/or (c) the introduction of, changeover to or operation of
       the euro in any participating member state:

       12.1.1  a Bank or any holding company of such Bank is unable to obtain
               the rate of return on its capital which it would have been able
               to obtain but for such Bank's entering into or assuming or
               maintaining a commitment, issuing or performing its obligations
               under this Agreement or any Letter of Credit;

       12.1.2  a Bank or any holding company of such Bank incurs a cost as a
               result of such Bank's entering into or assuming or maintaining a
               commitment, issuing or performing its obligations under this
               Agreement or any Letter of Credit; or

                                      -30-



       12.1.3  there is any increase in the cost to a Bank or any holding
               company of such Bank of funding or maintaining such Bank's share
               of any Unpaid Sum or any Letter of Credit,

       then the Account Party shall, from time to time on demand of the Agent,
       promptly pay to the Agent for the account of that Bank amounts sufficient
       to indemnify that Bank or to enable that Bank to indemnify its holding
       company from and against, as the case may be, (a) such reduction in the
       rate of return of capital, (b) such cost or (c) such increased cost.

12.2   Increased Costs Claims
       A Bank intending to make a claim pursuant to Clause 12.1 (Increased
       Costs) shall notify the Agent of the event giving rise to such claim and
       the amount of such claim and the basis for calculation of such amount in
       reasonable detail whereupon the Agent shall notify the Account Party
       thereof.

12.3   Exclusions
       Notwithstanding the foregoing provisions of this Clause 12, no Bank shall
       be entitled to make any claim under this Clause 12 in respect of:

       12.3.1  any cost, increased cost or liability as referred to in Clause
               12.1 (Increased Costs) to the extent the same is compensated by
               the Mandatory Liquid Asset Costs Rate; or

       12.3.2  any cost, increased cost or liability compensated by Clause 10
               (Taxes).

13.    ILLEGALITY
       If, at any time, it is or will become unlawful or prohibited pursuant to
       any request from or requirement of any central bank or other fiscal,
       monetary or other authority (being a request or requirement with which
       banks are accustomed to comply) for a Bank to fund, issue, participate in
       or allow to remain outstanding all or part of its share of the Letters of
       Credit, then that Bank shall, promptly after becoming aware of the same,
       deliver to the Account Party through the Agent a notice to that effect
       and:

       13.1.1  such Bank shall not thereafter be obliged to participate in any
               Letter of Credit or issue any Letter of Credit (whichever shall
               be so affected) and the amount of its Available Commitment shall
               be immediately reduced to zero; and

       13.1.2  if the Agent on behalf of such Bank so requires, the Account
               Party shall on such date as the Agent shall have specified ensure
               that the liabilities of such Bank under or in respect of each
               affected Letter of Credit are reduced to zero or otherwise
               secured by providing Cash Collateral in an amount equal to such
               Bank's L/C Proportion of such Letters of Credit or such Bank's
               maximum actual or contingent liabilities under such Letter of
               Credit.

14.    MITIGATION

       If, in respect of any Bank, circumstances arise which would or would upon
       the giving of notice result in:

                                      -31-



       14.1.1  an increase in any sum payable to it or for its account pursuant
               to Clause 10.1 (Tax Gross-up);

       14.1.2  a claim for indemnification pursuant to Clause 10.2 (Tax
               Indemnity) or Clause 12.1 (Increased Costs); or

       14.1.3  the reduction of its Available Commitment to zero or any
               repayment to be made pursuant to Clause 13 (Illegality),

       then, without in any way limiting, reducing or otherwise qualifying the
       rights of such Bank or the obligations of the Obligors under any of the
       Clauses referred to in sub-clauses 14.1.1, 14.1.2 and 14.1.3 such Bank
       shall promptly upon becoming aware of such circumstances notify the Agent
       thereof and, in consultation with the Agent and the Account Party and to
       the extent that it can do so lawfully and without prejudice to its own
       position, take reasonable steps (including a change of location of its
       Facility Office or the transfer of its rights, benefits and obligations
       hereunder to another financial institution which is an Approved Credit
       Institution and which is acceptable to the Account Party and willing to
       participate in the Facility) to mitigate the effects of such
       circumstances, provided that such Bank shall be under no obligation to
       take any such action if, in the opinion of such Bank, to do so might have
       any adverse effect upon its business, operations or financial condition
       (other than any minor costs and expenses of an administrative nature).

       affecting, the Account Party or any of its Subsidiaries before any court
       or arbitrator or any governmental body, agency or official in which there

       returns and all other material tax returns which are required to be filed

       where the necessity of compliance therewith is contested in good faith by
       appropriate proceedings and any reserves required under generally
       accepted accounting principles with respect thereto have been established
       and except where any such failure could not reasonably be expected to
       materially adversely affect the business, consolidated financial position
       or consolidated results of operations of the Account Party and its
       Consolidated Subsidiaries, considered as a whole.

15.9   Lien
       15.9.1  Each Obligor has good and marketable title in and to its portion

                Liens" as defined in the Charge Agreement.

       15.9.4   Neither Obligor is subject to any agreement, judgment,
                injunction, order, decree or other instrument or any law or
                regulation which would prevent or otherwise interfere with such
                Obligor's obligations to deliver Security in the amounts, at the
                times and as otherwise provided in the Charge Agreement, subject
                to the interest of the Custodian under the Finance Documents.

       the date hereof and shall only be repeated on each day commencing on the
       date on which the Pricing Level is Level V.

       All acts, conditions and things required to be done, fulfilled and
       performed in order:

       15.10.1  to enable each Obligor lawfully to enter into, exercise its
                rights under and perform and comply with the obligations
                expressed to be assumed by it in the Finance Documents to which
                it is a party,

       15.10.2  to ensure that the obligations expressed to be assumed by it in
                the Finance Documents to which it is a party are legal, valid,
                binding and enforceable; and

       15.10.3  to make the Finance Documents to which it is a party admissible
                in evidence in its jurisdiction of incorporation,

       have been done, fulfilled and performed (subject to any exception
       contained in the legal opinions provided as conditions precedent).

15.11  Claims Pari Passu
       Under the laws of its jurisdiction of incorporation in force at the date
       of this Agreement, the claims of the Finance Parties against each Obligor
       under this Agreement will rank at least pari passu with the claims of all
       its other unsecured and unsubordinated creditors save those claims which
       are preferred solely by any bankruptcy, insolvency, liquidation or other
       similar laws of general application or are mandatorily preferred by law
       applying to insurance companies generally.

15.12  No Filing or Stamp Taxes
       Under the laws of the jurisdiction of incorporation of each Obligor in
       force at the date of this Agreement, it is not necessary that the Finance

       court or other authority in such jurisdiction or that any stamp,
       registration or similar tax be paid on or in relation to the Finance
       Documents to which it is party.

15.13  No Winding-up
       No Obligor or Material Subsidiary has taken any corporate action nor have
       any other steps been taken or legal proceedings been started or (to the
       best of its knowledge and belief) threatened against any Obligor or
       Material Subsidiary for its winding-up, dissolution, administration or
       re-organisation (whether by voluntary arrangement, scheme of arrangement
       or otherwise) or for the appointment of a receiver, administrator,

                                      -35-



       administrative receiver, conservator, custodian, trustee or similar
       officer of it or of any or all of its assets or revenues.

      liabilities, except where the same may be contested in good faith by

      16.4.1  the merger of a Subsidiary (other than the Guarantor) into the
              Account Party or the merger or consolidation of a Subsidiary
              (other than the Guarantor) with or into another Person if the
              corporation surviving such consolidation or merger is a Subsidiary
              and if, in each case, after giving effect thereto, no Default
              shall have occurred and be continuing;

      16.4.2  any merger of any Obligor permitted by Clause 16.10

      material respects with all applicable laws, ordinances, rules,
      regulations, guidelines and other requirements of governmental authorities
      except where the necessity of compliance therewith is contested in good
      faith by appropriate proceedings and any reserves required under generally
      accepted accounting principles with respect thereto have been established
      and except where any such failure to comply could not reasonably be
      expected to materially adversely affect the business, consolidated
      financial position or consolidated results of operations of the Account
      Party and its Consolidated Subsidiaries, considered as a whole.

16.6  Inspection of Property, Books and Records
      The Account Party will keep, and will cause each Subsidiary to keep,
      proper books of records and account in accordance with generally accepted
      accounting principles in which full, true and correct entries shall be
      made of all dealings and transactions in relation to its business and
      activities; and will permit, and will cause each Subsidiary to permit,
      representatives of any Bank at such Bank's expense to visit and inspect
      any of their respective properties, to examine and make abstracts from any
      of their respective books and records and to discuss their respective

      If the Obligors are required to grant security pursuant to sub-clause

      observe or perform any covenant relating to the delivery of the Security
      and the perfection of the first priority charge and security interest

      the market value of the Charged Portfolio falls below the Required Value
      or the Charged Portfolio fails to satisfy the Security Trustee's
      Requirements (as defined in the Charge Agreement), such circumstances
      shall not constitute an Event of Default if the market value of the
      Charged Portfolio is restored to the Required Value and/or, as the case
      may be, the Security Trustee's Requirements are satisfied in each case
      within five Business Days of notification by the Security Trustee on

17.18 Acceleration and Cancellation
      Upon the occurrence of an Event of Default at any time thereafter while

      17.18.1 require the Account Party to procure that the liabilities of each
              of the Banks under each Letter of Credit are promptly reduced to
              zero and/or provide Cash Collateral for each Letter of Credit in
              an amount specified by the Agent (whereupon the Account Party
              shall do so); and/or

      17.18.2 declare that any unutilised portion of the Facility shall be
              cancelled, whereupon the same shall be cancelled and the Available

              assets subject to the Security Documents and the books and records
              relating

                                      -46-



              thereto, with or without judicial process. For the purposes of the
              preceding sentence, the Security Trustee may enter upon any or all
              of the premises where any of the assets subject to the Security
              Documents, such other security or books or records may be situated

              (for distribution in proportion to each Bank's L/C Proportion of
              such Letter of Credit) a letter of credit commission in sterling
              at the L/C Commission Rate on the maximum actual and contingent
              liabilities of the Banks under the relevant Letter of Credit. Such
              Letter of Credit Commission shall be paid quarterly in arrear in
              respect of each successive period of three months (or such shorter

              the Required Value) shall (subject to Section 25.21.3) be
              increased to an amount equal to the aggregate amount of the
              Letters of Credit issued hereunder, and each Obligor shall
              promptly (and in any event within five Business Days) perform its
              obligations under clause 4 of the Charge Agreement. Upon the

              received legal opinions in form and substance satisfactory to the
              Security Trustee (acting reasonably) opining that the Charge
              Agreement creates in favour of the Security Trustee on behalf of
              the Banks a valid and enforceable first priority Lien on all of
              the Security (subject to such qualifications and assumptions as
              are customarily made by leading firms of solicitors in giving
              legal opinions of that nature), the L/C Commission Rate shall
              become 0.15 per cent. and the Security Trustee shall notify all
              parties hereto accordingly.

      18.1.3  Any change to the L/C Commission Rate shall take effect on the day
              on which the event giving rise to such change occurs (whether
              pursuant to Schedule 9 (Pricing Schedule) or pursuant to
              sub-clause 18.1.2).

       sum is discharged shall be divided into successive periods, each of which
       (other than the first) shall start on the last day of the preceding such

       20.4.1   the additional interest which would have been payable on the
                amount so received or recovered had it been received or
                recovered on the last day of that Term

       exceeds

                of that Term in respect of

                                      -49-

       22.1.4  each payment pursuant to Clause 10.2 (Tax Indemnity) or Clause
               12.1 (Increased Costs) shall be made in the currency specified by
               the party claiming thereunder; and

       22.1.5  any amount expressed to be payable in a currency other than
               sterling shall be paid in that other currency.

23.    PAYMENTS

23.1   Payments to the Agent
       On each date on which this Agreement requires an amount to be paid by an
       Obligor, such Obligor shall make the same available to the Agent for
       value on the due date at such time and in such funds and to such account
       with such bank as the Agent shall specify from time to time upon
       reasonable advance notice to such Obligor.

23.2   Payments by the Agent
       Save as otherwise provided herein, each payment received by the Agent
       pursuant to Clause 23.1 (Payments to the Agent) shall be made available
       by the Agent to the person entitled to receive such payment in accordance
       with this Agreement (in the case of a Bank, for the account of its
       Facility Office) for value the same day by transfer to such account of
       such person with such bank in the principal financial center of the
       country of the currency of such payment as such person shall have
       previously notified to the Agent.

23.3   No Set-off
       All payments required to be made by an Obligor hereunder shall be
       calculated without reference to any set-off or counterclaim and shall be

       set-off or counterclaim.

23.4   Clawback
       Where a sum is to be paid hereunder to the Agent for the account of
       another person, the Agent shall not be obliged to make the same available
       to that other person or to enter into or perform any exchange contract in
       connection therewith until it has been able to establish to its
       satisfaction that it has actually received such sum, but if it does so
       and it proves to be the case that it had not actually received such sum,
       then the person to whom

                                      -51-



       such sum or the proceeds of such exchange contract was so made available
       shall on request refund the same to the Agent together with an amount
       sufficient to indemnify the Agent against any cost or loss it may have
       suffered or incurred by reason of its having paid out such sum or the
       proceeds of such exchange contract prior to its having received such sum.

23.5   Partial Payments
       If and whenever a payment is made by an Obligor hereunder and the Agent
       receives an amount less than the due amount of such payment the Agent may
       apply the amount received towards the obligations of the Obligors under
       this Agreement in the following order:

       23.5.1  first, in or towards payment of any unpaid costs and expenses of
               each of the Agent and the Arrangers;

       23.5.2  second, in or towards payment pro rata of any accrued interest,
               Letter of Credit Commission or fees payable to any Bank hereunder
               due but unpaid;

       23.5.3  third, in or towards payment pro rata of any Outstandings due but
               unpaid; and

       23.5.4  fourth, in or towards payment pro rata of any other sum due but
               unpaid.

23.6   Variation of Partial Payments
       The order of partial payments set out in Clause 23.5 (Partial Payments)
       shall override any appropriation made by the Obligors to which the
       partial payment relates but the order set out in sub-clauses 23.5.2,
       23.5.3 and 23.5.4 of Clause 23.5 (Partial Payments) may be varied if
       agreed by all the Banks.

23.7   Appropriations of proceeds of enforcement of Security
       If the Agent recovers any moneys from the enforcement of any Finance
       Document in its capacity as Agent or Security Trustee thereunder, it

       23.7.1  first, in payment of all costs, charges, expenses and liabilities
               (and all interest thereon as provided in the Finance Documents)
               incurred by or on behalf of the Agent and the Security Trustee
               and any receiver, attorney or agent in connection with the due
               performance of its duties and exercise of its powers and
               discretions under the Finance Documents and the remuneration of
               the Agent, the Security Trustee and every receiver under the
               Finance Documents;

       23.7.2  secondly, in or towards payment pro rata of any due but unpaid
               costs and expenses of the Agent, the Arrangers and the Banks
               under the Finance Documents;

       23.7.3  thirdly, in or towards payment pro rata of any accrued interest,
               Letter of Credit Commission or fees due but unpaid under this
               Agreement;

       23.7.4  fourthly, in or towards payment pro rata of any Outstandings due
               but unpaid under this Agreement;

                                      -52-



       23.7.5  fifthly, in or towards payment pro rata of any other sum due but
               unpaid under the Finance Documents; and

       23.7.6  sixthly, in payment of the surplus (if any) to the Account Party
               or any other person entitled thereto.

       The order of application of money recovered in this Clause may only be
       varied with the consent of all the Banks.

24.    SET-OFF

24.1   Contractual Set-off
       Each Obligor authorises each Bank at any time after an Event of Default
       has occurred which is continuing to apply any credit balance to which
       such Obligor is entitled on any account of such Obligor with such Bank in
       satisfaction of any sum due and payable from such Obligor to such Bank
       hereunder (whether by way of collateralisation or otherwise) but unpaid.
       For this purpose, each Bank is authorised to purchase with the moneys
       standing to the credit of any such account such other currencies as may
       be necessary to effect such application.

24.2   Set-off not Mandatory
       No Bank shall be obliged to exercise any right given to it by Clause 24.1
       (Contractual Set-off).

25.    SHARING

25.1   Payments to Banks
       If a Bank (a "Recovering Bank") applies any receipt or recovery from an
       Obligor to a payment due under this Agreement and such amount is received
       or recovered other than in accordance with Clause 23 (Payments), then
       such Recovering Bank shall:

       25.1.1  notify the Agent of such receipt or recovery;

       25.1.2  at the request of the Agent, promptly pay to the Agent an amount
               (the "Sharing Payment") equal to such receipt or recovery less
               any amount which the Agent determines may be retained by such
               Recovering Bank as its share of any payment to be made in
               accordance with Clause 23.5 (Partial Payments).

25.2   Redistribution of Payments
       The Agent shall treat the Sharing Payment as if it had been paid by the
       relevant Obligor and distribute it between the Finance Parties (other
       than the Recovering Bank) in accordance with Clause 23.5 (Partial
       Payments).

25.3   Recovering Bank's Rights
       The Recovering Bank will be subrogated to the rights of the parties which
       have shared in a redistribution pursuant to Clause 25.2 (Redistribution
       of Payments) in respect of the Sharing Payment (and the relevant Obligor
       shall be liable to the Recovering Bank in an amount equal to the Sharing
       Payment) in place of any corresponding liability to the parties which
       have shared in the redistribution.

                                      -53-



25.4   Repayable Recoveries
       If any part of the Sharing Payment received or recovered by a Recovering
       Bank becomes repayable and is repaid by such Recovering Bank, then:

       25.4.1  each party which has received a share of such Sharing Payment
               pursuant to Clause 25.2 (Redistribution of Payments) shall, upon
               request of the Agent, pay to the Agent for account of such
               Recovering Bank an amount equal to its share of such Sharing
               Payment; and

       25.4.2  such Recovering Bank's rights of subrogation in respect of any
               reimbursement shall be cancelled and the relevant Obligor will be
               liable to the reimbursing party for the amount so reimbursed.

25.5   Exception
       This Clause 25 shall not apply if the Recovering Bank would not, after
       making any payment pursuant hereto, have a valid and enforceable claim
       against the relevant Obligor.

25.6   Recoveries Through Legal Proceedings
       If any Bank intends to commence any action in any court it shall give
       prior notice to the Agent and the other Banks. If any Bank shall commence
       any action in any court to enforce its rights hereunder and, as a result
       thereof or in connection therewith, receives any amount, then such Bank
       shall not be required to share any portion of such amount with any Bank
       which has the legal right to, but does not, join in such action or
       commence and diligently prosecute a separate action to enforce its rights
       in another court.

26.    THE AGENT, THE ARRANGERS AND THE BANKS

26.1   Appointment of the Agent
       The Arrangers and each of the Banks hereby appoints the Agent to act as
       its agent in connection herewith and authorises the Agent to exercise

       26.2.1  assume, unless it has, in its capacity as agent for the Banks,
               received notice to the contrary from any other party hereto, that
               (a) any representation made or deemed to be made by an Obligor in
               connection with the Finance Documents is true, (b) no Event of
               Default or Potential Event of Default has occurred, (c) no
               Obligor is in breach of or default under its obligations under
               the Finance Documents and (d) any right, power, authority or
               discretion vested therein upon the Majority Banks, the Banks or
               any other person or group of persons has not been exercised;

       26.2.2  assume that the Facility Office of each Bank is that notified to
               it by such Bank in writing prior to the date hereof (or, in the
               case of a Transferee, at the end of

                                      -54-



               the Transfer Certificate to which it is a party as Transferee)
               until it has received from such Bank a notice designating some
               other office of such Bank to replace its Facility Office and act
               upon any such notice until the same is superseded by a further
               such notice;

       26.2.3  engage and pay for the advice or services of any lawyers,
               accountants, surveyors or other experts whose advice or services
               may to it seem necessary, expedient or desirable and rely upon
               any advice so obtained;

       26.2.4  rely as to any matters of fact which might reasonably be expected
               to be within the knowledge of an Obligor upon a certificate
               signed by or on behalf of such Obligor;

       26.2.5  rely upon any communication or document believed by it to be
               genuine;

       26.2.6  refrain from exercising any right, power or discretion vested in
               it as agent hereunder unless and until instructed by the Majority
               Banks as to whether or not such right, power or discretion is to
               be exercised and, if it is to be exercised, as to the manner in
               which it should be exercised;

       26.2.7  refrain from acting in accordance with any instructions of the
               Majority Banks to begin any legal action or proceeding arising
               out of or in connection with the Finance Documents until it shall
               have received such security as it may require (whether by way of
               payment in advance or otherwise) for all costs, claims, losses,
               expenses (including legal fees) and liabilities together with any
               VAT thereon which it will or may expend or incur in complying
               with such instructions; and

       26.2.8  assume (unless it has specific notice to the contrary) that any
               notice or request made by the Account Party is made on behalf of
               both Obligors.

26.3   Agent's Obligations
       The Agent shall:

       26.3.1  promptly inform each Bank of the contents of any notice or
               document received by it in its capacity as Agent from an Obligor
               under the Finance Documents and shall promptly deliver to each
               Bank a copy of each Letter of Credit delivered to Lloyd's
               pursuant to Clause 3.3 (Completion of Letters of Credit);

       26.3.2  promptly notify each Bank of the occurrence of any Event of
               Default or any default by an Obligor in the due performance of or
               compliance with its obligations under the Finance Documents of
               which the Agent has notice from any other party hereto;

       26.3.3  save as otherwise provided herein, act as agent under the Finance
               Documents in accordance with any instructions given to it by an
               Majority Banks, which instructions shall be binding on the
               Arrangers and the Banks; and

       26.3.4  if so instructed by the Majority Banks, refrain from exercising
               any right, power or discretion vested in it as agent under the
               Finance Documents.

                                      -55-



       The Agent's duties under the Finance Documents are solely mechanical and
       administrative in nature.

26.4   Excluded Obligations
       Notwithstanding anything to the contrary expressed or implied herein,
       neither the Agent nor the Arrangers shall:

       26.4.1  be bound to enquire as to (a) whether or not any representation
               made or deemed to be made by an Obligor in connection with the
               Finance Documents is true, (b) the occurrence or otherwise of any
               Default, (c) the performance by an Obligor of its obligations
               under the Finance Documents or (d) any breach of or default by an
               Obligor of or under its obligations under the Finance Documents;

       26.4.2  be bound to account to any Bank for any sum or the profit element
               of any sum received by it for its own account;

       26.4.3  be bound to disclose to any other person any information relating
               to any member of the Group if (a) such person, on providing such
               information, expressly stated to the Agent or, as the case may
               be, the Arrangers, that such information was confidential or (b)
               such disclosure would or might in its opinion constitute a breach
               of any law or be otherwise actionable at the suit of any person;

       26.4.4  be under any obligations other than those for which express
               provision is made herein; or

       26.4.5  be or be deemed to be a fiduciary for any other party hereto.

26.5   Indemnification
       Each Bank shall, in its Proportion, from time to time on demand by the
       Agent, indemnify the Agent against any and all costs, claims, losses,
       expenses (including legal fees) and liabilities together with any VAT
       thereon which the Agent may incur, otherwise than by reason of its own
       gross negligence or wilful misconduct, in acting in its capacity as agent
       hereunder (other than any which have been reimbursed by the Account Party
       pursuant to Clause 21.1 Company's Indemnity).

26.6   Exclusion of Liabilities
       Except in the case of gross negligence or wilful default, neither the
       Agent nor the Arrangers accepts any responsibility:

       26.6.1  for the adequacy, accuracy and/or completeness of any information
               supplied by the Agent or the Arrangers, by an Obligor or by any
               other person in connection with the Finance Documents or any
               other agreement, arrangement or document entered into, made or
               executed in anticipation of, pursuant to or in connection with
               the Finance Documents;

       26.6.2  for the legality, validity, effectiveness, adequacy or
               enforceability of the Finance Documents or any other agreement,
               arrangement or document entered into, made or executed in
               anticipation of, pursuant to or in connection with the Finance
               Documents; or

                                      -56-



       26.6.3  for the exercise of, or the failure to exercise, any judgement,
               discretion or power given to any of them by or in connection with
               the Finance Documents or any other agreement, arrangement or
               document entered into, made or executed in anticipation of,
               pursuant to or in connection with the Finance Documents.

       Accordingly, neither the Agent nor the Arrangers shall be under any
       liability (whether in negligence or otherwise) in respect of such
       matters, save in the case of gross negligence or wilful misconduct.

26.7   No Actions
       Each of the Banks agree that it will not assert or seek to assert against
       any director, officer or employee of the Agent or the Arrangers any claim
       it might have against any of them in respect of the matters referred to
       in Clause 26.6 (Exclusion of Liabilities).

26.8   Business with the Group
       The Agent and the Arrangers may accept deposits from, lend money to and
       generally engage in any kind of banking or other business with any member
       of the Group.

26.9   Resignation
       The Agent may resign its appointment hereunder at any time without
       assigning any reason therefor by giving not less than thirty days' prior
       notice to that effect to each of the other parties hereto, provided that
       no such resignation shall be effective until a successor for the Agent is
       appointed in accordance with the succeeding provisions of this Clause 26.

26.10  Removal of Agent
       The Majority Banks may remove the Agent from its role as agent hereunder
       after consultation with the Account Party by giving notice to that effect
       to each of the other parties hereto. Such removal shall take effect only
       when a successor to the Agent is appointed in accordance with the terms
       hereof.

26.11  Successor Agent
       If the Agent gives notice of its resignation pursuant to Clause 26.9
       (Resignation) or it is removed pursuant to Clause 26.10 (Removal of
       Agent) then any reputable and experienced bank or other financial
       institution may be appointed as a successor to the Agent by the Majority
       Banks (after consultation with the Account Party if the successor is a
       Bank or otherwise with the Account Party's prior written consent) during
       the period of such notice (with the co-operation of the Agent), subject
       to such entity executing and delivering a confidentiality undertaking
       substantially in the form set out in Schedule 8 (Form of Confidentiality
       Undertaking) but, if no such successor is so appointed, the Agent may
       appoint such a successor itself.

26.12  Rights and Obligations
       If a successor to the Agent is appointed under the provisions of Clause
       26.11 (Successor Agent), then (a) the retiring Agent shall be discharged
       from any further obligation hereunder but shall remain entitled to the
       benefit of the provisions of this Clause 26 and (b) its successor and
       each of the other parties hereto shall have the same rights and
       obligations amongst themselves as they would have had if such successor
       had been a party hereto.

                                       -57-



26.13   Own Responsibility
        It is understood and agreed by each Bank that at all times it has itself
        been, and will continue to be, solely responsible for making its own
        independent appraisal of and investigation into all risks arising under
        or in connection with this Agreement including, but not limited to:

        26.13.1  the financial condition, creditworthiness, condition, affairs,
                 status and nature of each member of the Group;

        26.13.2  the legality, validity, effectiveness, adequacy and
                 enforceability of the Finance Documents and any other
                 agreement, arrangement or document entered into, made or
                 executed in anticipation of, pursuant to or in connection with
                 the Finance Documents;

        26.13.3  whether such Bank has recourse, and the nature and extent of
                 that recourse, against an Obligor or any other person or any of
                 its assets under or in connection with the Finance Documents,
                 the transactions therein contemplated or any other agreement,
                 arrangement or document entered into, made or executed in
                 anticipation of, pursuant to or in connection with the Finance
                 Documents; and

        26.13.4  the adequacy, accuracy and/or completeness of any information
                 provided by the Agent or the Arrangers, an Obligor or by any
                 other person in connection with the Finance Documents, the
                 transactions contemplated therein or any other agreement,
                 arrangement or document entered into, made or executed in
                 anticipation of, pursuant to or in connection with the Finance
                 Documents.

        Accordingly, each Bank acknowledges to the Agent and the Arrangers that
        it has not relied on and will not hereafter rely on the Agent and the
        Arrangers or either of them in respect of any of these matters.

26.14   Agency Division Separate
        In acting as agent hereunder for the Banks, the Agent shall be regarded
        as acting through its agency division which shall be treated as a
        separate entity from any other of its divisions or departments and,
        notwithstanding the foregoing provisions of this Clause 26, any
        information received by some other division or department of the Agent
        may be treated as confidential and shall not be regarded as having been
        given to the Agent's agency division.

26.15   Declaration of Agent as Security Trustee
        The Agent hereby declares that it shall hold:

        26.15.1  all rights, titles and interests that may hereafter be
                 mortgaged, charged, assigned or otherwise secured in favour of
                 the Agent by or pursuant to the Finance Documents;

        26.15.2  the benefit of all representations, covenants, guarantees,
                 indemnities and other contractual provisions given in favour of
                 the Agent (other than any such benefits given to the Agent
                 solely for its own benefit) by or pursuant to the Finance
                 Documents (other than this Agreement); and

                                      -58-



        26.15.3  all proceeds of the security referred to in sub-clause 26.15.1
                 above and of the enforcement of the benefits referred to in
                 26.15.2 above,

        on trust for itself and the other Finance Parties from time to time.

        Such declaration shall remain valid notwithstanding that the Agent may
        on the date hereof or at any other time be the sole Finance Party; for
        the avoidance of doubt, however, such declaration shall, in such case,
        be deemed repeated on each date on which the Agent ceases to be the sole
        Finance Party.

        Each of the parties hereto agrees that the obligations, rights and
        benefits vested or to be vested in the Agent as trustee as aforesaid
        by the Finance Documents or any document entered into pursuant thereto
        shall (as well before as after enforcement) be performed and (as the
        case may be) exercised by the Agent in accordance with the provisions
        of this Clause 26.

26.16   Powers and Discretions
        The Agent shall have all the powers and discretions conferred upon
        trustees by the Trustee Act 1925 (to the extent not inconsistent
        herewith) and by way of supplement it is expressly declared as follows:

        26.16.1  the Agent shall be at liberty to place any of the Finance
                 Documents and any other instruments, documents or deeds
                 delivered to it pursuant thereto or in connection therewith for
                 the time being in its possession in any safe deposit, safe or
                 receptacle selected by the Agent or with any bank, any company
                 whose business includes undertaking the safe custody of
                 documents or any firm of lawyers of good repute;

        26.16.2  the Agent may, whenever it thinks fit, delegate by power of
                 attorney or otherwise to any person or persons or fluctuating
                 body of persons all or any of the rights, trusts, powers,
                 authorities and discretions vested in it by any of the Finance
                 Documents and such delegation may be made upon such terms and
                 subject to such conditions (including the power to
                 sub-delegate) and subject to such regulations as the Agent may
                 think fit and the Agent shall not be bound to supervise, or be
                 in any way responsible for any loss incurred by reason of any
                 misconduct or default on the part of, any such delegate (or
                 sub-delegate);

        26.16.3  notwithstanding anything else herein contained, the Agent may
                 refrain from doing anything which would or might in its opinion
                 be contrary to any law of any jurisdiction or any directive or
                 regulation of any agency of any state or which would or might
                 otherwise render it liable to any person and may do anything
                 which is, in its opinion, necessary to comply with any such
                 law, directive or regulation;

        26.16.4  save in the case of gross negligence or wilful misconduct, the
                 Agent and every attorney, agent, delegate, sub-delegate and any
                 other person appointed by any of them under any of the Finance
                 Documents may indemnify itself or himself out of the security
                 held by the Agent against all liabilities, costs, fees,
                 charges, losses and expenses incurred by any of them in
                 relation to or arising out of the

                 taking or holding of any of the security constituted by, or
                 any of the benefits provided by, any of the Finance Documents,
                 in the exercise or purported exercise of the rights, trusts,
                 powers and discretions vested in any of them or in respect of
                 any other matter or thing done or omitted to be done in any
                 way relating to any of the Finance Documents or pursuant to
                 any law or regulation; and

        26.16.5  without prejudice to the provisions of any of the Finance
                 Documents, the Agent shall not be under any obligation to
                 insure any property or to require any other person to maintain
                 any such insurance and shall not be responsible for any loss
                 which may be suffered by any person as a result of the lack of
                 or inadequacy or insufficiency of any such insurance.

26.17   Liability
        The Agent shall not be liable for any failure:

        26.17.1  to require the deposit with it of any deed or document

                 the documents of title of the Account Party;

        26.17.4  to effect or procure registration of or otherwise protect any
                 of the security created by any of the Finance Documents by

                 any territory or otherwise by registering any notice, caution

        subject matter of any of the Finance Documents and shall not be bound or
        concerned to investigate or make any enquiry into the right or title of
        the Account Party to such property (or any part thereof) or, without
        prejudice to the foregoing, to require the Account Party to remedy any

        The Agent may at any time appoint any person (whether or not a trust
        corporation) to act either as a separate trustee or as a co-trustee
        jointly with the Agent:

        26.19.1  if the Agent considers such appointment to be in the interests
                 of the Banks; or

        26.19.2  for the purposes of conforming to any legal requirements,
                 restrictions or conditions which the Agent deems relevant for

                 prior notice to the Account Party and the Banks of any such
                 appointment.

        Any person so appointed shall (subject to the provisions of the Finance

        appointed.

        Such reasonable remuneration as the Agent may pay to any person so
        appointed, and any costs, charges and expenses incurred by such person
        in performing its functions pursuant to such appointment, shall for the
        purposes hereof be treated as costs, charges and expenses incurred by
        the Agent under the Finance Documents.

26.21   Security
        26.21.1  In the event that the Required Value is greater than US$100
                 pursuant to sub-clause 18.1.2 of Clause 18.1 (Letter of Credit
                 Commission), as soon as reasonably practicable after each
                 delivery to the Security Trustee of the statement(s) of the
                 Charged Portfolio by the Custodian pursuant to paragraph 3 of
                 the Custodian's Undertaking and in any event within seven
                 Business Days of such delivery, the Security Trustee and the
                 Obligors shall adjust the Required Value to the extent
                 necessary to ensure that the Required Value of the Charged
                 Portfolio is an amount equal to the aggregate of:

                 A + (A x Y per cent.) + B + (B x Y per cent.) +C + (C x Y per
                 cent.)

                 where:

                 A    represents the amount of the Charged Portfolio denominated
                      in sterling

                 B    represents the amount of the Charged Portfolio denominated
                      in dollars (converted into sterling at the Spot Rate)

                                      -61-

                       denominated in any currency other than sterling or
                       dollars (converted into sterling at the Spot Rate)

                  Y per cent. means:

                 (a)  10 per cent. in respect of any portion of the Charged
                      Portfolio denominated in sterling;

                 (b)  10 per cent. in respect of any portion of the Charged
                      Portfolio denominated in dollars; and

                 (c)  15 per cent. in respect of any portion of the Charged

                 level IV or above (each as defined in Schedule 9 (Pricing
                 Schedule), the Required Value will revert to US$100. For the
                 avoidance of doubt, if, following any such reduction in the
                 Required Value, the Pricing Level again reaches Level V, the
                 Required Value shall be increased to the extent required
                 pursuant to sub-clause 18.1.2 of Clause 18.1 (Letter of Credit

                 Agent on the Bank's behalf has been duly authorised by all
                 necessary action on the part of the Bank; and

        26.22.2  the obligations of the Bank under each Letter of Credit
                 constitute its legal, valid and binding obligations.

26.23   Letters of Credit
        Each Bank shall in its Proportion, indemnify the Agent against any and
        all liabilities, costs and expenses which the Agent may incur (in its

27.3    Assignments and Transfers by Banks
        Subject to obtaining the prior written consent of the Account Party
        (such consent not to be unreasonably withheld or delayed), any Bank may,

        Finance Documents or transfer in accordance with Clause 27.5 (Transfers
        by Banks) all or any of its rights, benefits and obligations under the

        27.3.1   no such assignment or transfer of the whole or any part of the
                 Commitment may be made unless it is to an Approved Credit
                 Institution; and

        27.3.2   the Account Party's consent is not required if such assignment
                 or transfer is:

                 (a)  to any subsidiary or holding company, or to any subsidiary
                      of any holding company, of such Bank; or

        notice to the Agent confirming in favour of the Agent, the Arrangers and
        the Banks that it shall be under the same obligations towards each of
        them as it would have been under if it had been an original party hereto
        as a Bank (whereupon such assignee shall become a party hereto as a
        "Bank"), the Agent, the Arrangers, and the Banks shall not be obliged to
        recognise such assignee as having the rights against each of them which
        it would have had if it had been such a party hereto.

27.5    Transfers by Banks
        If any Bank wishes to transfer all or any of its rights, benefits and/or
        obligations under the Finance Documents as contemplated in Clause 27.3
        (Assignments and Transfers by Banks), then such transfer may be effected
        by the delivery to the Agent of a duly completed Transfer Certificate
        executed by such Bank and the relevant Transferee in which event, on the
        later of the Transfer Date specified in such Transfer Certificate and
        the fifth Business Day after (or such earlier Business Day endorsed by
        the Agent on such Transfer Certificate falling on or after) the date of
        delivery of such Transfer Certificate to the Agent:

        27.5.1   to the extent that in such Transfer Certificate the Bank party
                 thereto seeks to transfer by novation its rights, benefits and
                 obligations under the Finance Documents, each of the Obligors
                 and such Bank shall be released from further obligations
                 towards one another under the Finance Documents and their
                 respective rights against one another shall be cancelled (such
                 rights and obligations being referred to in this Clause 27.5 as
                 "discharged rights and obligations");

                                      -63-



        27.5.2   each of the Obligors and the Transferee party thereto shall
                 assume obligations towards one another and/or acquire rights
                 against one another which differ from such discharged rights
                 and obligations only insofar as such Obligor and such
                 Transferee have assumed and/or acquired the same in place of
                 such Obligor and such Bank;

        27.5.3   the Agent, the Arrangers, the Security Trustee, such Transferee
                 and the other Banks shall acquire the same rights and benefits
                 and assume the same obligations between themselves as they
                 would have acquired and assumed had such Transferee been an
                 original party hereto as a Bank with the rights, benefits
                 and/or obligations acquired or assumed by it as a result of
                 such transfer and to that extent the Agent, the Arrangers and
                 the relevant Bank shall each be released from further
                 obligations to each other under the Finance Documents; and

        27.5.4   such Transferee shall become a party hereto as a "Bank".

        the Bank transferring all or any of its rights, benefits and/or
        obligations under the Finance Documents shall ensure that the Account
        Party will procure the release by Lloyd's of each Letter of Credit (an
        "Old Letter of Credit") with respect to which the transfer is to have
        effect and its replacement by a new Letter of Credit to be issued by the
        Transferee and all the other Banks in an amount equal to that of the Old
        Letter of Credit and having a Termination Date which corresponds with
        the Termination Date thereof.

27.7    Transfer Fees
        On the date upon which a transfer takes effect pursuant to Clause 27.5

        confidentiality undertaking substantially in the form set out in
        Schedule 8 (Form of Confidentiality Agreement).

      30.1 (Guarantee and Indemnity) may, in that Bank's discretion, be credited
      to an interest bearing suspense or impersonal account and may be held in
      such account for so long as such Bank thinks fit pending the application

      Party to such Bank under the Finance Documents.

31.1  Remedies and Waivers
      No failure to exercise, nor any delay in exercising, on the part of any
      Finance Party, any right or remedy hereunder shall operate as a waiver

      prevent any further or other exercise thereof or the exercise of any other
      right or remedy. The rights and remedies herein provided are cumulative
      and not exclusive of any rights or remedies provided by law.

31.2  Partial Invalidity
      If, at any time, any provision of the Finance Documents is or becomes

                                   SCHEDULE 7

                        Mandatory Liquid Asset Costs Rate

1.   For the purposes of this Agreement, the cost of compliance with existing
     requirements of the Bank of England and/or the Financial Services Authority
     will be calculated by the Agent in relation to each Unpaid Sum on the basis
     of rates supplied by the Agent (or such Bank(s) as it may from time to time
     determine) by reference to the circumstances existing on the first day of
     each Term in respect of such Unpaid Sum and, if any such Term of such
     Unpaid Sum exceeds three months, at three calendar monthly intervals from
     the first day of such Term during its duration in accordance with the
     following formula:

     (a)  in relation to Unpaid Sums denominated in Sterling:

                            AB + C(B - D) + E x 0.01      per cent. per annum
                            ------------------------
                                  100 - (A + C)

     (b)  in relation to Unpaid Sums denominated in dollars:

                                    E x 0.01              per cent. per annum
                                    --------
                                       300

Where:

          A    is the percentage of eligible liabilities (assuming these to be
               in excess of any stated minimum) which the Agent (or such Bank as
               it may determine) is from time to time required to maintain as an
               interest free cash ratio deposit with the Bank of England to
               comply with cash ratio requirements.

          B    is the percentage rate per annum at which sterling deposits are
               offered by the Agent (or such Bank as it may determine) in
               accordance with its normal practice, for a period equal to (a)
               the relevant Term (or, as the case may be, remainder of such
               Term) in respect of the relevant Unpaid Sum or (b) three months,
               whichever is the shorter, to a leading bank in the London
               Interbank Market as of 11.00 a.m. in a sum approximately equal to
               the amount of such Unpaid Sum.

          C    is the percentage of eligible liabilities which the Agent (or
               such Bank as it may determine) is required from time to time to
               maintain as interest bearing special deposits with the Bank of
               England.

          D    is the percentage rate per annum payable by the Bank of England
               to the Agent (or such Bank as it may determine) on interest
               bearing special deposits.

          E    is the rate payable by the Agent (or such Bank as it may
               determine) to the Financial Services Authority pursuant to the
               Fees Regulations (but, for this purpose, ignoring any minimum fee
               required pursuant to the

                                      -90-



               Fees Regulations) and expressed in Pounds per (Pounds)1,000,000
               of the Fee Base of the Agent (or such Bank as it may determine).

2.   For the purposes of this Schedule:

     (i)   "eligible liabilities" and "special deposits" shall bear the meanings
           ascribed to them from time to time under or pursuant to the Bank of
           England Act 1998 or (as may be appropriate) by the Bank of England;

     (ii)  "Fee Regulations" means the Banking Supervision (Fees) Regulations
           2001 or such other regulation as may be in force from time to time in
           respect of the payment of fees for banking supervision; and

     (iii) "Fee Base" shall bear the meaning ascribed to it, and shall be
           calculated in accordance with, the Fees Regulations.

3.   The percentages used in A and C above shall be those required to be
     maintained on the first day of the relevant period as determined in
     accordance with B above.

4.   In application of the above formula, A, B, C and D will be included in the
     formula as figures and not as percentages e.g. if A is 0.5 per cent. and B
     is 12 per cent., AB will be calculated as 0.5 x 12 and not as 0.5 per cent.
     x 12 per cent.

5.   Calculations will be made on the basis of a 365 day year (or, if market
     practice differs, in accordance with market practice).

6.   A negative result obtained by subtracting D from B shall be taken as zero.

7.   The resulting figures shall be rounded to four decimal places.

8.   Additional amounts calculated in accordance with this Schedule are payable
     on the last day of the Term to which they relate.

9.   The determination of the Mandatory Liquid Asset Costs Rate by the Agent in
     relation to any period shall, in the absence of manifest error, be
     conclusive and binding on all of the parties hereto.

10.  The Agent may from time to time, after consultation with the Account Party
     and the Banks, determine and notify to all parties any amendments or
     variations which are required to be made to the formula set out above in
     order to comply with any requirements from time to time imposed by the Bank
     of England or the Financial Services Authority in relation to any Unpaid
     Sum and any such determination shall, in the absence of manifest error, be
     conclusive and binding on all the parties hereto.

                                      -91-

      (Payments).

                                      -97-



     It is a condition precedent to the obligations of the Banks under the
     Agreement that the Chargors shall have granted the security interests and
     undertaken the obligations contemplated by this Charge Agreement.

     NOW, THEREFORE, in consideration of the premises and in order to induce the
     Banks to issue Letters of Credit under the Agreement and for other good and
     valuable consideration, the receipt and adequacy of which are hereby
     acknowledged, each Chargor hereby agrees with the Security Trustee as
     follows:

1.   PAYMENT AND DISCHARGE

     We shall pay and discharge in full all of the Obligations at the times and
     in the manner provided for in the Agreements.

2.   CHARGE

2.1  Each Chargor hereby pledges and assigns to the Security Trustee, and hereby
     grants to the Security Trustee a security interest in, its portion of the
     Charged Portfolio as collateral security for the prompt payment or
     performance in full when due, whether at stated maturity, by required
     prepayment, declaration, acceleration, demand or otherwise (including the
     payment of amounts that would become due but for the operation of the
     automatic stay under Section 362(a) of the United States Bankruptcy Code,
     11 U.S.C. 362(a)), of all Obligations.

2.2  Notwithstanding any provision of the Agreement to the contrary, the
     Security Trustee's entitlement and recourse against the Charged Portfolio
     under this Charge Agreement shall not in any circumstances exceed an amount
     equal to the Required Value.

2.3  Each Chargor shall deposit all of its portion of the Charged Portfolio in
     the accounts comprising the Charged Portfolio and held with the Custodian.

3.   CUSTODIAN'S UNDERTAKING

     We undertake to deliver (or procure the delivery of) the Custodian's
     Undertaking to you forthwith upon the execution of this Charge Agreement.

4.   REQUIRED VALUE

     We undertake to ensure that with effect from the date of this Charge
     Agreement and at all times thereafter until the Obligations are discharged
     in full:

4.1  the market value of the Charged Portfolio (including the accounts and
     securities of both Chargors) shall not be less than the Required Value and
     without limitation from time to time to pay or transfer to the Custodian
     (by way of increment to the Charged Portfolio) money and/or securities so
     that the market value of each Chargor's portion of the Charged Portfolio
     (including the accounts and securities of both Chargors) shall not be less
     than the Required Value; and

4.2  each component part of the Charged Portfolio shall satisfy the Security
     Trustee's Requirements applicable thereto.

                                      -98-



5.   FURTHER ASSURANCE

     Each Chargor agrees that from time to time, at the expense of such Chargor,
     such Chargor shall promptly execute and deliver all further instruments and
     documents, and take all further action, that may be necessary or desirable,
     or that the Security Trustee may reasonably request, in order to perfect
     and protect any security interest granted or purported to be granted hereby
     or to enable the Security Trustee or the Custodian to exercise and enforce
     its rights and remedies hereunder or under the Custodian's Undertaking with
     respect to any part of such Chargor's portion of the Charged Portfolio.
     Without limiting the generality of the foregoing, each Chargor shall: (a)
     execute and file such assignments, financing or continuation statements, or
     amendments thereto, and such other instruments or notices, as may
     reasonably be necessary or desirable, or as the Security Trustee may
     request, in order to perfect and preserve the security interests granted or
     purported to be granted hereby, and (b) at the Security Trustee's request,
     appear in and defend any action or proceeding that may affect such
     Chargor's title to or the Security Trustee's security interest in all or
     any part of such Chargor's portion of the Charged Portfolio.

6.   REPRESENTATIONS AND WARRANTIES

     Each Chargor hereby represents and warrants to you and undertakes that:

6.1  it is (or at the time of transfer thereof to the Custodian will be) the
     beneficial owner of its portion of the Charged Portfolio from time to time
     transferred by it to the Custodian, as agent for the Security Trustee, free
     and clear of any lien other than Permitted Liens in accordance with the
     undertaking contained in Clause 7 (Negative Pledge) hereof, except for the
     security interest created by this Charge Agreement. The pledge and
     assignment of the Charged Portfolio pursuant to this Charge Agreement and
     the Custodian's Undertaking creates a valid security interest in its
     portion of the Charged Portfolio securing the payment of the Obligations.
     Assuming execution and due performance of the Custodian's Undertaking by
     the Custodian, the security interest in the Charged Portfolio is or will be
     perfected and senior in priority to any other lien therein;

6.2  subject to paragraph 11 of the Custodian's Undertaking, it has not sold or
     agreed to sell or otherwise disposed of or agreed to dispose of the benefit
     of its portion of the Charged Portfolio or any part thereof;

6.3  it has and will at all times have the necessary power to enable it to enter
     into and perform the obligations expressed to be assumed by it under this
     Charge Agreement;

6.4  this Charge Agreement constitutes its legal, valid, binding and enforceable
     obligation (subject to bankruptcy, insolvency or other laws of general
     application affecting the enforcement of creditors' rights, the application
     of equitable principles and the non-availability of the equitable remedies
     of specific performance or injunctive relief) and is a security over its
     portion of the Charged Portfolio and every part thereof effective in
     accordance with its terms; and

6.5  all necessary authorisations to enable or entitle it to enter into this
     Charge Agreement have been obtained and are in full force and effect and
     will remain in full force and effect

                                      -99-



     at all times during the subsistence of the security hereby constituted and
     no authorisation, approval or other action by, and no notice to or filing
     with, any governmental authority or regulatory body is required for either
     (a) the grant by it of the security interest granted hereby, (b) the
     execution, delivery or performance of this Charge Agreement or the
     Custodian's Undertaking by it, or (c) the perfection of or the exercise by
     Security Trustee or the Custodian of its rights and remedies hereunder or
     under the Custodian's Undertaking.

6.6  All information heretofore, herein or hereafter supplied to the Security
     Trustee or the Custodian by or on behalf of it with respect to its portion
     of the Charged Portfolio is accurate and complete in all material respects.

7.   NEGATIVE PLEDGE

     Each Chargor undertakes with you that at no time during the subsistence of
     the security interest granted hereby will it, otherwise than:

7.1  in your favour, or

7.2  with your prior written consent and in accordance with and subject to any
     conditions which you may attach to such consent,

     create, grant, extend or permit to subsist any lien, security interest or
     other encumbrance on or over its portion of the Charged Portfolio or any
     part thereof, other than Permitted Liens. The foregoing prohibition shall
     apply not only to any lien, security interest or other encumbrance which
     rank or purport to rank in point of security in priority to the security
     hereby constituted but also to any lien, security interest or other
     encumbrance which rank or purport to rank pari passu therewith or
     thereafter.

8.   POWER OF SALE

8.1  Upon the occurrence of an Event of Default which is continuing and has not
     been remedied or waived under the Agreement, the Security Trustee may
     instruct the Custodian to (a) sell or redeem any of the Charged Portfolio,
     (b) transfer any or all of the Charged Portfolio constituting cash to any
     account designated by the Security Trustee, including an account or
     accounts established in the Security Trustee's name (whether with the
     Security Trustee or the Custodian or otherwise), (c) register title to all
     or any portion of the Charged Portfolio in any name specified by the
     Security Trustee, including the name of the Security Trustee or any of its
     nominees or agents, without reference to any interest of the Chargors, or
     (d) otherwise deal with the Charged Portfolio as directed by the Security
     Trustee.

8.2  Upon the occurrence of an Event of Default which is continuing and has not
     been remedied or waived under the Agreement, the Security Trustee may
     exercise in respect of the Charged Portfolio, in addition to all other
     rights and remedies provided for herein or otherwise available to it, all
     the rights and remedies of a secured party on default under the Uniform
     Commercial Code as in effect in any relevant jurisdiction (the "UCC")
     (whether or not the UCC applies to the affected Charged Portfolio), and the
     Security Trustee may also in its sole discretion sell the Charged Portfolio
     or any part thereof in one or more parcels at public or private sale, at
     any exchange or broker's board

                                      -100-



     or at any of the Security Trustee's offices or elsewhere, for cash, on
     credit or for future delivery, at such time or times and at such price or
     prices and upon such other terms as the Security Trustee may deem
     commercially reasonable, irrespective of the impact of any such sales on
     the market price of the Charged Portfolio. Each purchaser at any such sale
     shall hold the property sold absolutely free from any claim or right on the
     part of the Chargors, and each Chargor hereby waives (to the extent
     permitted by applicable law) all rights of redemption, stay or appraisal
     which it now has or may at any time in the future have under any rule of
     law or statute now existing or hereafter enacted. The Security Trustee
     shall not be obligated to make any sale of Charged Portfolio regardless of
     notice of sale having been given. The Security Trustee may adjourn any
     public or private sale from time to time by announcement at the time and
     place fixed therefor, and such sale may, without further notice, be made at
     the time and place to which it was so adjourned.

8.3  Each Chargor hereby agrees that the property included in the Charged
     Portfolio is of a type customarily sold on recognized markets and,
     accordingly, that no notice to any person is required before any sale of
     any of the Charged Portfolio pursuant to the terms of this Charge
     Agreement; provided that, without prejudice to the foregoing, each Chargor
     agrees that, to the extent notice of any such sale shall be required by
     law, at least ten days' notice to it of the time and place of any public
     sale or the time after which any private sale is to be made shall
     constitute reasonable notification.

8.4  If the proceeds of any sale or other disposition of the Charged Portfolio
     are insufficient to pay all the Obligations, the Chargors shall be liable
     for the deficiency and the fees of any attorneys employed by the Security
     Trustee to collect such deficiency.

8.5  Anything contained herein to the contrary notwithstanding, any of the
     Charged Portfolio consisting of a deposit or an other obligation of the
     Security Trustee, whether credited to the Charged Portfolio or otherwise,
     shall be subject to the Security Trustee's rights of set-off.

9.   POWER OF ATTORNEY

9.1  Each Chargor hereby irrevocably appoints the Security Trustee as its
     attorney-in-fact, with full authority in the place and stead of such
     Chargor and in the name of such Chargor, the Security Trustee or otherwise,
     from time to time in the Security Trustee's discretion upon the occurrence
     of an Event of Default which is continuing and has not been remedied or
     waived under the Agreement, to take any action and execute and deliver, any
     instrument that the Security Trustee may reasonably deem necessary or
     advisable to accomplish the purposes of this Charge Agreement or the
     Custodian's Undertaking, including, without limitation, executing
     instruments of transfer (or completing partially completed instruments
     executed by us), assignments or notices, or exercising any of the rights
     and powers from time to time attaching to any part of such Chargor's
     portion of the Charged Portfolio. Each Chargor hereby undertakes to ratify
     and confirm all things done and documents executed by the Security Trustee
     in the exercise of the power of attorney conferred by this Clause.

9.2  If the Chargor fails to perform any agreement contained herein, the
     Security Trustee may itself perform, or cause performance of, such
     agreement, and the expenses of the Security

                                      -101-



      Trustee incurred in connection therewith shall be payable by the Chargor
      under Clause 14 (Exculpation, Costs, Charges and Expenses).

10.   EFFECTIVENESS OF SECURITY

10.1  This Charge Agreement shall be in addition to and shall be independent of
      every other security which you may at any time hold for any of the
      Obligations. No prior security held by you over the whole or any part of
      the Charged Portfolio shall merge in the security hereby constituted.

10.2  Nothing contained in this Charge Agreement is intended to, or shall
      operate so as to, prejudice or affect any bill, note, guarantee, mortgage,
      pledge, charge or other security of any kind whatsoever which you may have
      for the Obligations or any of them or any right, remedy or privilege of
      yours thereunder.

11.   REMEDIES, TIME OR INDULGENCE

11.1  The rights, powers and remedies provided by this Charge Agreement are
      cumulative and are not, nor are they to be construed as, exclusive of any
      right of set-off or other rights, powers and remedies provided by law.

11.2  No failure on your part to exercise, or delay on your part in exercising,
      any of the rights, powers and remedies provided by this Charge Agreement
      or by law (each a "Security Trustee Right") shall operate as a waiver
      thereof, nor shall any single or partial waiver of a Security Trustee
      Right preclude any further or other exercise of that Security Trustee
      Right or the exercise of any other Security Trustee Right.

11.3  You may in your discretion grant time or other indulgence or make any
      other arrangement, variation or release with any person(s) not party
      hereto (irrespective of whether such person(s) is/are jointly liable with
      us) in respect of the Obligations or in any way affecting or concerning
      them or any of them or in respect of any security for the Obligations or
      any of them, without in any such case prejudicing, affecting or impairing
      the security hereby constituted, or any Security Trustee Right or the
      exercise of the same, or any indebtedness or other liability owed by
      either of us to you.

12.   ACCOUNTS

      All monies received, recovered or realised by you under this Charge
      Agreement (including the proceeds of any conversion of currency) may in
      your discretion be credited to any suspense or impersonal account and may
      be held in such account for so long as you shall think fit (with interest
      accruing thereon at such rate, if any, as you may deem fit) pending their
      application from time to time (as you shall be entitled to do in your
      discretion) in or towards the discharge of any of the Obligations.

13.   CURRENCY

13.1  For the purpose of or pending the discharge of any of the Obligations you
      may convert any monies received, recovered or realised or subject to
      application by you under this Charge Agreement (including the proceeds of
      any previous conversion under this Clause) from their existing currency of
      denomination into the currency of denomination

                                      -102-



      of such Obligations as you may think fit, and any such conversion shall be
      effected at your then prevailing spot rate of exchange for obtaining such
      other currency with the existing currency.

13.2  References herein to any currency extend to any funds of that currency and
      for the avoidance of doubt funds of one currency may be converted into
      different funds of the same currency.

14.   EXCULPATION, COSTS, CHARGES AND EXPENSES

14.1  The powers conferred on the Security Trustee hereunder are solely to
      protect its interest in the Charged Portfolio and shall not impose any
      duty upon it to exercise any such powers. Except for the exercise of
      reasonable care in the custody of any portion of the Charged Portfolio in
      its possession and the accounting for moneys actually received by it
      hereunder, the Security Trustee shall have no duty as to any Charged
      Portfolio, it being understood that the Security Trustee shall have no
      responsibility for (a) ascertaining or taking action with respect to
      calls, conversions, exchanges, maturities, tenders or other matters
      relating to any Charged Portfolio, whether or not the Security Trustee has
      or is deemed to have knowledge of such matters, (b) taking any necessary
      steps (other than steps taken in accordance with the standard of care set
      forth above to maintain possession of the Charged Portfolio) to preserve
      rights against any parties with respect to any Charged Portfolio, (c)
      taking any necessary steps to collect or realise upon the Obligations or
      any guarantee therefor, or any part thereof, or any of the Charged
      Portfolio, (d) initiating any action to protect the Charged Portfolio
      against the possibility of a decline in market value, (e) any loss
      resulting from investments made, held or sold, or (f) determining (i) the
      correctness of any statement or calculation made by a Chargor in any
      written instructions or (ii) whether any transfer to or from the Charged
      Portfolio is proper. The Security Trustee shall be deemed to have
      exercised reasonable care in the custody and preservation of Charged
      Portfolio in its possession if such Charged Portfolio is accorded
      treatment substantially equal to that which the Security Trustee accords
      its own property of like kind. In addition to the foregoing and without
      limiting the generality thereof, the Security Trustee shall not be
      responsible for any actions or omissions of Custodian.

14.2  Each Chargor agrees to indemnify the Security Trustee from and against any
      and all claims, losses and liabilities in any way relating to, growing out
      of or resulting from this Charge Agreement and the transactions
      contemplated hereby (including enforcement of this Charge Agreement),
      except to the extent such claims, losses or liabilities result from the
      Security Trustee's gross negligence or wilful misconduct as finally
      determined by a court of competent jurisdiction.

14.3  Each Chargor shall pay to the Security Trustee upon demand the amount of
      any and all costs and expenses, including the reasonable fees and expenses
      of its counsel and of any experts and agents, that the Securities Trustee
      may incur in connection with (a) the administration of this Charge
      Agreement, (b) the custody, preservation, use or operation of, or the sale
      of, collection from, or other realisation upon, any of the Charged
      Portfolio, (c) the exercise or enforcement of any of the rights of the
      Security Trustee hereunder, or (d) the failure by a Chargor to perform or
      observe any of the provisions hereof on a full

                                      -103-



      indemnity basis together with interest from the date of the same having
      been incurred (or from the date of demand if such demand is made after
      unreasonable delay) to the date of payment at such rate or rates as you
      may determine in relation to the currency involved.

15.   CONTINUING SECURITY INTEREST

      This Charge Agreement shall create a continuing security interest in the
      Charged Portfolio and shall (a) remain in full force and effect until the
      indefeasible payment in full of the Obligations and the cancellation or
      expiration of all outstanding Letters of Credit, (b) be binding upon each
      Chargor, its successors and assigns, and (c) inure, together with the
      rights and remedies of the Security Trustee hereunder, to the benefit of
      Security Trustee and the Banks and their respective successors,
      transferees and assigns. Upon the indefeasible payment in full of all
      Obligations and the cancellation or expiration of all outstanding Letters
      of Credit, the security interest granted hereby shall terminate and all
      rights to the Charged Portfolio shall revert to the respective Chargor so
      long as the Custodian's fees, expenses, and advancements have first been
      paid or reimbursed in full. Upon any such termination the Security Trustee
      shall, at the Chargors' expense, execute and deliver to the Chargors such
      documents as the Chargors shall reasonably request to evidence such
      termination and each Chargor shall be entitled to the return, upon its
      request and at its expense, against receipt and without recourse to the
      Security Trustee, of such of its Charged Portfolio as shall not have been
      sold or otherwise applied pursuant to the terms hereof.

16.   AMENDMENTS

      No amendment or waiver of any provision of this Charge Agreement, or
      consent to any departure by a Chargor herefrom, shall in any event be
      effective unless the same shall be in writing and signed by the Security
      Trustee, and then such waiver or consent shall be effective only in the
      specific instance and for the specific purpose for which it was given.

17.   LAW AND JURISDICTION

17.1  THIS AGREEMENT SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED
      IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK, WITHOUT
      REGARD TO CONFLICTS OF LAWS PRINCIPLES, EXCEPT TO THE EXTENT THAT THE UCC
      PROVIDES THAT THE VALIDITY OR PERFECTION OF THE SECURITY INTEREST
      HEREUNDER, OR REMEDIES HEREUNDER, IN RESPECT OF ANY PARTICULAR COLLATERAL
      ARE GOVERNED BY THE LAWS OF A JURISDICTION OTHER THAN THE STATE OF NEW
      YORK.

17.2  ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST THE CHARGORS ARISING OUT OF OR
      RELATING TO THIS CHARGE AGREEMENT MAY BE BROUGHT IN ANY STATE OR FEDERAL
      COURT OF COMPETENT JURISDICTION IN THE STATE, COUNTY AND CITY OF NEW YORK,
      AND BY EXECUTION AND DELIVERY OF THIS CHARGE AGREEMENT EACH CHARGOR
      ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND
      UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS AND
      WAIVES ANY DEFENSE

      OF FORUM NON CONVENIENS AND IRREVOCABLY AGREES TO BE BOUND BY ANY JUDGMENT
      RENDERED THEREBY IN CONNECTION WITH THIS CHARGE AGREEMENT. Each Chargor
      hereby agrees that service of all process in any such proceeding in any
      such court may be made by registered or certified mail, return receipt
      requested, to such Chargor at its address as provided pursuant to Clause
      19 (Notices), such service being hereby acknowledged by each Chargor to be
      sufficient for personal jurisdiction in any action against such Chargor in
      any such court and to be otherwise effective and binding service in every
      respect. Nothing herein shall affect the right to serve process in any
      other manner permitted by law or shall limit the right of the Security
      Trustee to bring proceedings against a Chargor in the courts of any other
      jurisdiction.

17.3  EACH CHARGOR AND THE SECURITY TRUSTEE HEREBY AGREE TO WAIVE THEIR
      RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED
      UPON OR ARISING OUT OF THIS CHARGE AGREEMENT OR THE CUSTODIAN'S
      UNDERTAKING. The scope of this waiver is intended to be all-encompassing
      of any and all disputes that may be filed in any court and that relate to
      the subject matter of this transaction, including contract claims, tort
      claims, breach of duty claims, and all other common law and statutory
      claims. Each Chargor and the Security Trustee acknowledge that this waiver
      is a material inducement for such Chargor and the Security Trustee to
      enter into a business relationship, that each Chargor and the Security
      Trustee have already relied on this waiver in entering into this Charge
      Agreement and that each will continue to rely on this waiver in their
      related future dealings. Each Chargor and the Security Trustee further
      warrant and represents that it has reviewed this waiver with its legal
      counsel, and that it knowingly and voluntarily waives its jury trial
      rights following consultation with legal counsel. THIS WAIVER IS
      IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN
      WRITING, AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS,
      RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS CHARGE AGREEMENT OR THE
      CUSTODIAN'S UNDERTAKING. In the event of litigation, this Charge Agreement
      may be filed as a written consent to a trial by the court.

18.   PROVISIONS SEVERABLE

      Each of the provisions contained in this Charge Agreement shall be
      severable and distinct from one another and if at any time any one or more
      of such provisions is or becomes invalid, illegal or unenforceable, the
      validity, legality and enforceability of each of the remaining provisions
      of this Charge Agreement shall not in any way be affected, prejudiced or
      impaired thereby.

19.   NOTICES

      All notices, requests and demands to or upon the Security Trustee or
      either Chargor hereunder shall be effected in the manner provided for in

To:  the Security Trustee

We, the Custodian, refer to the afore-mentioned Charge Agreement (the "Charge
Agreement") between the Chargors and the Security Trustee. Save where the
context otherwise requires, terms defined in the Charge Agreement shall have the
same meanings herein.

In consideration of the Security Trustee and the other Finance Parties entering
into the Agreement and issuing Letters of Credit thereunder and pursuant to
instructions received by the Custodian from the Chargors, the Custodian hereby
represents and irrevocably undertakes and agrees to and with the Security
Trustee as follows:

1.   The Custodian acknowledges the security interest granted by each Chargor in
     favor of Security Trustee in the Charged Portfolio.

2.   Anything contained herein to the contrary notwithstanding, the Custodian
     will, without further consent by any Chargor (a) comply with Entitlement
     Orders originated by the Security Trustee with respect to the Charged
     Portfolio and any Security Entitlements carried therein, (b) transfer, sell
     or redeem any of the Charged Portfolio as directed by the Security Trustee,
     (c) transfer any or all of the Charged Portfolio to any account or accounts
     designated by the Security Trustee, including an account established in the
     Security Trustee's name (whether at the Security Trustee or the Custodian
     or otherwise), (d) register title to any of the Charged Portfolio in any
     name specified by the Security Trustee, including the name of the Security
     Trustee or any of its nominees or agents, without reference to any interest
     of either Chargor, or (e) otherwise deal with the Charged Portfolio as
     directed by the Security Trustee.

3.   The Custodian hereby further acknowledges that it holds the Charged
     Portfolio, all Security Entitlements carried therein, and all other
     collateral held by the Custodian under this Custodian's Undertaking or the
     Charge Agreement, as custodian for the benefit of, and subject to the
     control of, the Security Trustee. The Custodian shall, by book entry or
     otherwise, indicate that the Charged Portfolio, and all Security
     Entitlements carried therein, are subject to the control of the Security
     Trustee as provided in Section 2.

4.   The Custodian hereby represents and warrants (a) that the records of
     Custodian show that each Chargor is the sole owner of such Chargor's
     portion of the Charged Portfolio, (b) that the Custodian has not been
     served with any notice of levy or received any notice of any security
     interest in or other claim to the Charged Portfolio, or any portion of the
     Charged Portfolio, other than Security Trustee's claim pursuant to the
     Charge Agreement, (c) that the Custodian is not presently obliged to accept
     any entitlement order from any person with respect to the Charged
     Portfolio, except for entitlement orders that the Custodian is obligated to
     accept from the Security Trustee under this undertaking and entitlement
     orders that the Custodian, subject to the provisions of Section 10 below,
     is obligated to accept from the Chargors, (d) that the Custodian has all
     necessary corporate power and authority to enter into and perform this
     undertaking, (e) that the execution, delivery and performance of this
     undertaking by the Custodian have been duly authorized by all necessary
     corporate action on the part of the Custodian, (f) that the Custodian is a
     "securities intermediary" (as that term is defined in Section 8-102(a)(14)
     of the Uniform Commercial Code as in effect in the state of New York (the
     "Code")) and is acting in such capacity with respect to the Charged
     Portfolio and (g) that the Custodian

                                      -113-



     is not a "clearing corporation" (as that term is defined in Section
     8-102(a)(5) of the Code).

5.   Without the prior written consent of the Security Trustee, the Custodian
     will not enter into any agreement by which the Custodian agrees to comply
     with any entitlement order of any person other than the Security Trustee
     or, subject to the provisions of Section 10 below, the Chargors, with
     respect to any portion or all of the Charged Portfolio. The Custodian (a)
     shall promptly notify the Security Trustee if any person requests the
     Custodian to enter into any such agreement or otherwise assert or seeks to
     assert a lien, encumbrance or adverse claim against any portion or all of
     the Charged Portfolio and (b) will not acknowledge any limitation on the
     right of Security Trustee to originate "entitlement orders" (as such term
     is defined in Section 8-102(8) of the Code, "Entitlement Orders") with
     respect to or direct the transfer of the Charged Portfolio or any portion
     thereof.

6.   The Custodian hereby agrees that: (a) each account comprising the Charged
     Portfolio established by the Custodian (each, a "Charged Account") is and
     will be maintained as a "securities account" (within the meaning of Section
     8-501 of the Code); (b) any credit balances or other property, other than
     cash, credited to, or held for the credit of, any such Charged Account
     shall be treated as "financial assets" (within the meaning of Section
     8-102(a)(9) of the Code, "Financial Assets") and (c) each Chargor is an
     "entitlement holder" (within the meaning of Section 8-102(a)(7) of the
     Code) in respect of the Financial Assets credited to such Charged Account
     and with respect to such Charged Account and Custodian shall so note in its
     records pertaining to such Financial Assets and each Charged Account; and
     (d) all Financial Assets in registered form or payable to or to the order
     of and credited to any such Charged Account shall be registered in the name
     of, payable to or to the order of, or specially endorsed to, the Custodian
     or in blank, or credited to another securities account maintained in the
     name of the Custodian, and in no case will any Financial Asset credited to
     any such Charged Account be registered in the name of, payable to or to the
     order of, or endorsed to, either Chargor except to the extent the foregoing
     have been subsequently endorsed by such Chargor to the Custodian or in
     blank.

7.   The Custodian will deliver to the Security Trustee within three business
     days of the Security Trustee's request therefor an up-to-date statement or
     statements of the Charged Portfolio, each component thereof and the
     aggregate value thereof.

8.   The Custodian will in any event deliver to the Security Trustee not later
     than the tenth business day of each calendar month a statement or
     statements, made up as at the close of business on the last business day of
     the preceding calendar month, of the Charged Portfolio, each component
     thereof and the aggregate value thereof.

9.   If trades of, or any transactions relating to, a component part of the
     Charged Portfolio are processed by the Custodian on any Business Day, the
     Custodian shall notify the Security Trustee as soon as possible (and in any
     event within three Business Days of such day) of the trades and
     transactions processed.

10.  The Custodian acknowledges that the Security Trustee has the right, by
     delivery of written notice (a "Prohibition Notice") to the Custodian, to
     prohibit each Chargor from

                                      -114-



     effecting any withdrawals, sales, trades, transfers or exchanges of any of
     the Charged Portfolio and the Custodian agrees that upon delivery of a
     Prohibition Notice, the Custodian will cease to honor instructions from
     either of the Chargors with respect to the Charged Portfolio and will
     comply with any and all written instructions delivered by the Security
     Trustee to the Custodian and has no obligation to and will not, investigate
     the reason for any action taken by the Security Trustee, the amount of any
     obligations of any Chargor to the Security Trustee, the validity of any of
     the Security Trustee's claims against or agreements with either Chargor,
     the existence of any defaults under such agreements, or any other matter.

11.  The Custodian acknowledges that, unless it receives written instructions
     from the Security Trustee to the contrary, it shall be entitled to process
     trades as it may be directed to do so under the terms of its custodial
     agreement with the [Chargors/each Chargor respectively] only to the extent
     such trades comprise a disposal to a third party in the market of a
     component part of the Charged Portfolio and the substitution therefor with
     the proceeds of such disposition or other securities, save that transfers
     can be made (a) to the Security Trustee in accordance with the terms of
     this undertaking or (b) to any person with the Security Trustee's prior
     written consent or (c) in respect of any part of the Charged Portfolio
     representing an excess over the Required Value, to the relevant Chargor or
     as it may direct, which excess will be determined by the Security Trustee
     and specified in written notice from the Security Trustee to the Custodian
     on the date of the request from the Chargors.

12.  After delivery of a Prohibition Notice, the Custodian shall deliver,
     transfer or assign to the Security Trustee on the Security Trustee's first
     written demand securities and monies in the Charged Portfolio as directed
     by the Security Trustee and all certificates and other instruments
     evidencing title thereto or necessary or desirable in order for the
     Security Trustee to acquire good and marketable title thereto. The Security
     Trustee shall indicate the identity of the securities and monies it wishes
     to receive and the Custodian shall have no discretion in this matter and
     shall be fully protected in relying upon any direction received from the
     Security Trustee.

13.  The Custodian agrees that it will not attempt to assert control, and does
     not claim and will not accept any security or other interest in any part of
     the Charged Portfolio, and will not exercise, enforce or attempt to enforce
     any claim, right of set-off, banker's lien, clearing lien, counterclaim or
     similar right against the Charged Portfolio or any portion thereof, or
     otherwise charge or deduct from the Charged Portfolio any amount
     whatsoever, except as provided below. All rights and interests of the
     Custodian in or towards the Charged Portfolio or any part thereof are and
     shall be subordinated and postponed to the Security Trustee's rights and
     interests therein under and pursuant to the Charge Agreement, save that the
     Custodian shall be entitled to debit any account of the relevant Chargor
     maintained with the Custodian with any reasonable fees or commissions due
     and owing by such Chargor to the Custodian in respect of the Charged
     Portfolio or part thereof or to settle any reasonable bank charges due and
     owing by such Chargor to the Custodian and incurred in the ordinary course
     of business for the purchase of securities and/or foreign exchange or
     contracts for foreign exchange.

                                      -115-



14.  Any notice, demand or other communication required to be:

     (a)  served on us by you hereunder, may be served by letter properly
          addressed and deposited with a recognised air express courier or
          transmitted by facsimile if (a) a telephone call is placed to the

          Undertaking notifying such officer of the facsimile transmission and

          procedures;

          of this Custodian's Undertaking, or to any substitute facsimile number
          or officer as you may notify to us.

15.  The Custodian shall not amend, supplement or otherwise modify its
     agreements with the Chargors or the Security Trustee governing the
     establishment and maintenance of the Charged Accounts (including, without
     limitation the choice of law provision and provisions providing for
     treatment of property held in any Charged Account as a financial asset) in
     any respect without the Security Trustee's prior written consent.

16.  This agreement shall remain in full force and effect until the Custodian
     receives written notice of its termination given by the Security Trustee
     and the Custodian shall not terminate the Charged Accounts, and shall not
     permit either Chargor to terminate the Charged Accounts, without the
     Security Trustee's prior written consent.

17.  The Custodian hereby acknowledges that in the event any dispute arises
     between one or both Chargors, on the one hand, and the Security Trustee, on
     the other hand, with respect to the payment, ownership or right to
     possession of the Charged Portfolio or any portion thereof, the Custodian
     shall take such actions and shall refrain from taking such actions with
     respect thereto as may be directed by the Security Trustee.

18.  THE CUSTODIAN AGREES that THIS UNDERTAKING shall be governed under and in
     accordance with the laws of the State of NEW YORK, without regard to
     conflict of laws principles AND FURTHER AGREES THAT ALL JUDICIAL
     PROCEEDINGS BROUGHT AGAINST THE CUSTODIAN ARISING OUT OF OR RELATING TO
     THIS AGREEMENT MAY BE BROUGHT IN THE ENGLISH COURTS OR ANY STATE OR FEDERAL
     COURT OF COMPETENT JURISDICTION IN THE STATE, COUNTY AND CITY OF NEW YORK.
     for purposes of this undertaking, the State of New York shall be deemed to
     be the Custodian's jurisdiction.

19.  Save as expressly provided herein, the Custodian shall have no further
     obligations or liabilities to the Security Trustee in relation to the
     Charged Portfolio and specifically shall have no liability or
     responsibility for monitoring or determining the compliance by any party
     with any other agreement including, without limitation, the Charge
     Agreement.
