4.      EXTENSION OF LETTERS OF CREDIT

4.1     Bank Notification
        Each Bank acknowledges that the Account Party may request one or more
        extensions of a Letter of Credit hereunder, and that pursuant to the
        terms thereof each Letter of Credit shall be extended automatically for
        a further year each year unless Lloyd's receives notice to the contrary.
        Accordingly, each Bank undertakes to notify the Agent in writing as soon
        as reasonably practicable after it has determined that it will not agree
        to a requested extension, and in any event by no later than close of
        business on the date which falls ten weeks prior to the first date which
        Lloyd's notifies as being the Funds Date of such year and the Agent
        shall give notice thereof to the Account Party within two Business Days
        of notification from such Bank. Unless notice is given to the Agent as
        aforesaid each Bank will be deemed automatically to have agreed to such
        extension.

4.2     Request for Extension
        If the Account Party wishes to request the extension of a Letter of
        Credit, the Account Party shall give the Agent notice, by way of a
        Letter of Credit extension request in the form of Schedule 5 (Form of
        Extension Request) by the date which falls thirteen weeks prior to the
        Funds Date of such year, specifying that the Expiry Date of the
        applicable Letter of Credit is to be extended to 31 December of the year
        immediately succeeding the year in which the then current Expiry Date
        falls (such notice being a "Notice of Extension"). A single Notice of
        Extension may be delivered in respect of more than one Letter of Credit.

4.3     Non-Delivery of Notice of Extension
        If the Account Party does not deliver a Notice of Extension in
        accordance with the provisions of Clause 4.2 (Request for Extension),
        the Agent shall:

        4.3.1     as soon as reasonably practicable after the date which falls
                  ten weeks prior to the Funds Date of such year, notify the
                  Account Party and then notify the Banks thereof; and

        4.3.2     as soon as reasonably practicable after the date which falls
                  ten weeks prior to the Funds Date of such year and in any
                  event by no later than close of business on the Business Day
                  immediately preceding the Funds Date of such

                                     -19-
<PAGE>

                  year, notify Lloyd's that the Term of the relevant Letter of
                  Credit will not be extended beyond its then current Expiry
                  Date.

4.4     Notification to Banks
        Upon receipt of a Notice of Extension, the Agent shall promptly notify
        each Bank of the contents thereof and of the amount of such Bank's
        participation in the applicable Letter of Credit, together with notice
        of the applicable Funds Date for such year.

4.5     Extension of a Letter of Credit

        4.5.1     If all of the Banks agree (or are deemed to have agreed) to
                  the extension of the Letter of Credit in accordance with
                  Clause 4.1 (Bank Notification) the Agent shall notify the
                  Account Party and the Banks thereof and subject to the
                  provisions of Clause 4.8 (Extension Conditions Precedent), the
                  Letter of Credit shall be automatically extended in accordance
                  with the terms thereof.

        4.5.2     If a Bank gives notice in accordance with the provisions of
                  Clause 4.1 (Bank Notification) that it does not agree to a
                  requested extension of any Letter of Credit the Agent shall
                  notify the Account Party and Lloyd's accordingly within two
                  Business Days thereafter, and the succeeding provisions of
                  this Clause 4 shall apply.

4.6     Substitute Bank

        4.6.1     If any Bank (a "Declining Bank") gives notice in accordance
                  with the provisions of Clause 4.1 (Bank Notification) that it
                  does not agree to a requested extension, then the Account
                  Party may designate by the date which falls four weeks prior
                  to the Funds Date of such 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").

        4.6.2     If the Account Party has found a Substitute Bank it shall
                  promptly notify the Agent and the Declining Bank thereof and
                  shall procure the release by Lloyd's of the Old Letter of
                  Credit from the Funds at Lloyd's of the relevant Applicant.

        4.6.3     The Declining Bank shall as soon as reasonably practicable and
                  in any event no later than the date which falls two weeks
                  prior to the Funds Date of such year transfer its rights and
                  obligations hereunder to the Substitute Bank in accordance
                  with the provisions of Clause 26.5 (Transfers by Banks).

        4.6.4     The Substitute Bank shall pay to the Declining Bank all
                  amounts then due and owing (and all fees accrued to but
                  excluding the date of such transfer) to the Declining Bank in
                  respect of its participation in the Old Letter of Credit.

4.7     Replacement Letters of Credit

        4.7.1     If a Substitute Bank has become party hereto pursuant to
                  Clause 4.6 (Substitute Bank), then subject to the provisions
                  of Clause 4.8 (Extension Conditions Precedent) the Banks who
                  have confirmed their agreement to the

                                     -20-
<PAGE>

                  extension of the Old Letter of Credit (the "Extending Banks")
                  shall, together with the Substitute Bank, participate in, and
                  issue by the Funds Date of such year, a new Letter of Credit
                  (the "New Letter of Credit") which shall (i) replace the Old
                  Letter of Credit, (ii) be in an amount equal to the Old Letter
                  of Credit and (iii) have an Expiry Date which corresponds with
                  the Expiry Date requested in the Notice of Extension.

        4.7.2     If a Substitute Bank has not been found then: (a) the Account
                  Party shall procure the release by Lloyd's of the 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 participate
                  in, and issue by the Funds Date of such year, a new Letter of
                  Credit (the "Reduced Letter of Credit") which shall (1)
                  replace their participation in the Old Letter of Credit, (2)
                  be in an amount equal to the Old Letter of Credit less the
                  amount of the Declining Bank's participation and (3) have an
                  Expiry Date which corresponds with the Expiry Date requested
                  in the Notice of Extension; and (c) the Declining Bank shall
                  participate in a separate Letter of Credit (a "Bilateral
                  Letter of Credit") which shall (1) replace its participation
                  in the Old Letter of Credit, (2) be in an amount equal to the
                  Declining Bank's participation in the Old Letter of Credit and
                  (3) have an Expiry Date which is the same as the Expiry Date
                  specified in the Old Letter of Credit (as the same may have
                  been extended from time to time with the consent of the
                  Declining Bank).

4.8     Extension Conditions Precedent

        4.8.1     On or prior to close of business on the Funds Date immediately
                  following the delivery of any Notice of Extension, the Account
                  Party shall promptly notify the Agent if:

                  (a)   an Event of Default or Potential Event of Default occurs
                        which is continuing;

                  (b)   any of the representations and warranties of the Account
                        Party contained in this Agreement or in the Charge
                        Agreement cease to be correct in all material respects,
                        or become misleading in any material respect; or

                  (c)   the Letter of Credit which is the subject of such Notice
                        of Extension ceases solely to be used to support the
                        relevant Applicant's underwriting business at Lloyd's
                        which has been provided in accordance with the
                        requirements of Lloyd's applicable to it.

        4.8.2     Subject to due notification to Lloyd's in accordance with the
                  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.

        Declining Bank the Account Party may give the Agent and the Declining
        Bank not less than fourteen days' prior written notice of its intention
        to procure that the liability of the Declining Bank under such Letter of

        If a Letter of Credit is automatically extended in accordance with the

        had failed to comply with its obligations under Clause 4 (Extension of
        Letters of Credit) or any of the events specified in sub-clause 4.8.1
        thereof had occurred, the Agent may (and if so instructed by the
        Majority Banks participating in such Letter of Credit shall) require the
        Account Party to procure that the liabilities of each of the Banks under
        such Letter of Credit are reduced to zero and/or provide Cash Collateral
        for each Bank's L/C Proportion under such Letter of Credit.

        change at or around the time of any given Funds Date in terms of amount

        and subject to each Bank's Outstandings under the Letters of Credit
        issued hereunder not being increased other than in accordance with
        Clause 5 (Increase of the Facility), the Banks shall co-operate with the
        Account Party to ensure to the extent reasonably possible that the
        Letters of Credit provide for the revised Funds at Lloyd's Requirements
        of the Applicants.

5.      INCREASE OF THE FACILITY

5.1     Request for Increase
        In the event that the Funds at Lloyd's Requirements of an Applicant
        increases at or around the time of any given Funds Date and as a result
        of such increase the aggregate amount of the Funds at Lloyd's
        Requirements of the Applicants on such Funds Date would exceed the
        aggregate amount of the Banks' Outstandings under the Letters of Credit,
        the Account Party shall be entitled to request an increase of the amount
        of the Letter of Credit of such Applicant by giving notice to the Agent
        no later than thirteen weeks prior to the Funds Date of such year (the
        "Increase Request"). The Increase Request shall be made in writing and
        shall be unconditional and irrevocable and shall specify:

        5.1.1    which Letters of Credit and Applicants the Increase Request
                 relates to;

        participation in any such increased Letter of Credit.

5.3     Response to Increase Request
        If a Bank, in its sole discretion, agrees to the increase requested by
        the Account Party pursuant to the Increase Request, it shall give notice
        to the Agent (a "Notice of Increase") accordingly not less than ten
        weeks prior to the Increase Date. If a Bank does not give such Notice of
        Increase by such date, then such Bank shall be deemed to have refused
        such increase. Nothing shall oblige a Bank to agree to the Increase
        Request.

5.4     Notification of Response to Increase Request
        The Agent shall notify the Account Party in writing of each Bank's
        decision in relation to the Increase Request (specifying which Banks
        have given a Notice of Increase, which Banks have actually refused the
        Increase Request and which Banks are deemed to have refused the Increase
        Request) no less than eight weeks prior to the Increase Date.

        5.5.1     If one or more of the Banks does not give a Notice of Increase
                  (hereinafter referred to as "Refusing Banks"), then the
                  Refusing Banks shall not participate in any increase pursuant
                  to the Increase Request but shall continue to participate in
                  the Letters of Credit to the extent of their existing
                  participation.

        5.5.2     If one or more Banks agree to the Increase Request such Banks'
                  participation in the relevant Letter(s) of Credit shall,
                  subject to satisfaction of any conditions precedent which may
                  be specified in connection therewith, be increased in
                  accordance with the terms of the Increase Request.

        5.5.3     The Account Party shall co-operate with the Agent, the Banks
                  and Lloyd's with respect to the replacement of any Letters of
                  Credit required as a result of an Increase Request and all
                  parties shall agree on any necessary replacement Letters of
                  Credit in the context of any replacement Letters of Credit
                  required in accordance with Clause 4.7 (Replacement Letters of
                  Credit).

        5.5.4     The Facility, save as amended pursuant to the Increase
                  Request, shall continue to operate in accordance with its

        Neither the obligations of the Account Party set out in this Clause 7
        nor the rights, powers and remedies conferred on any Bank by this
        Agreement or by law shall be discharged, impaired or otherwise affected
        by:

        7.2.1    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;

        7.2.2    any of the obligations of any Bank or any other person

        7.2.5    any other act, event or omission which, but for this Clause 7,

                 or any of the rights, powers or remedies conferred upon any

7.3     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.

        terms of the relevant Letter of Credit without any reference to or

        with any demand under a Letter of Credit which is valid on its face.

7.5     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:

        7.5.1     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

        7.5.2     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.

8.      CANCELLATION AND COLLATERALISATION

8.1     Cancellation/Cash Collateralisation of Letters of Credit
        The Account Party may give the Agent not less than fourteen days' prior
        notice of its intention to procure that the liability of each Bank under
        a Letter of Credit requested by it is reduced to zero (whereupon it
        shall do so) or provide Cash Collateral for each Bank's L/C Proportion
        under such Letter of Credit (whereupon it shall do so).

8.2     Notice of Cancellation or Collateralisation
        Any notice of cancellation or collateralisation given by the Account

        the amount of such cancellation or

                                     -25-

        collateralisation and shall oblige the Account Party to procure such

        If:

        8.3.1    any sum payable to any Bank by the Account Party is required to
                 be increased pursuant to Clause 9.1 (Tax Gross-up); or

        8.3.2    any Bank claims indemnification from the Account Party under
                 Clause 9.2 (Tax Indemnity) or Clause 11.1 (Increased Costs),

        the Account Party may, whilst such circumstance continues, give the
        Agent at least ten Business Days' notice (which notice shall be
        irrevocable) of its intention to cancel, and/or provide Cash Collateral
        in respect of the Commitment of such Bank.

8.4     Removal of a Bank
        On the day the notice referred to in Clause 8.3 (Notice of Removal of a
        Bank) expires the Account Party shall procure either that such Bank's
        L/C Proportion of each relevant Letter of Credit be reduced to zero (by
        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.

8.5     No Further Availability
        A Bank for whose account a repayment is to be made under Clause 8.3
        (Notice of Removal of a Bank) shall not be obliged to participate in the

        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.      TAXES

9.1     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.

                                     -26-
<PAGE>

9.2     Tax Indemnity
        Without prejudice to Clause 9.1 (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 9.2 shall not apply to:

        9.2.1     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

        9.2.2     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.

9.3     Banks' Tax Status Confirmation
        Each Bank confirms in favour of the Agent (on the date hereof or, in the
        case of a Bank which becomes a party hereto pursuant to a transfer or
        assignment, on the date on which the relevant transfer or assignment
        becomes effective) that either:

        9.3.1     it is a Qualifying Bank; or

        9.3.2     it is not resident for tax purposes in the United Kingdom and
                  is beneficially entitled to its share of the Outstandings and
                  any interest thereon.

9.4     Claims by Banks
        A Bank intending to make a claim pursuant to Clause 9.2 (Tax Indemnity)
        shall notify the Agent of the event giving rise to the claim, whereupon
        the Agent shall notify the Account Party thereof.

10.     TAX RECEIPTS

10.1    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.

10.2    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

                                     -27-
<PAGE>

        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.

10.3    Tax Credit Payment
        If an additional payment is made under Clause 9 (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:

        10.3.1    such credit, relief, remission or repayment is in respect of
                  or calculated with reference to the additional payment made
                  pursuant to Clause 9 (Taxes); and

        10.3.2    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.

10.4    Tax Credit Clawback
        If any Finance Party makes any payment to an Obligor pursuant to Clause
        10.3 (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.

10.5    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 8.1 (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.

11.     INCREASED COSTS

11.1    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

                                     -28-
<PAGE>

     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:

     11.1.1    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;

     11.1.2    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

     11.1.3    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, (i) such reduction in the
     rate of return of capital, (ii) such cost or (iii) such increased cost.

11.2 Increased Costs Claims

     A Bank intending to make a claim pursuant to Clause 11.1 (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.

11.3 Exclusions

     Notwithstanding the foregoing provisions of this Clause 11, no Bank shall
     be entitled to make any claim under this Clause 11 in respect of:

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

     11.3.2    any cost, increased cost or liability compensated by Clause 9
               (Taxes).

12.  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:

                                     -29-
<PAGE>

     12.1.1    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

     12.1.2    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.

13.  MITIGATION

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

     13.1.1    an increase in any sum payable to it or for its account pursuant
               to Clause 8.1 (Tax Gross-up);

     13.1.2    a claim for indemnification pursuant to Clause 9.2 (Tax
               Indemnity) or Clause 11.1 (Increased Costs); or

     13.1.3    the reduction of its Available Commitment to zero or any
               repayment to be made pursuant to Clause 12 (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 13.1.1, 13.1.2 and 13.1.3 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).

                   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

                   perform any material provision of the Custodian's Undertaking
                   and such failure, if in the reasonable opinion of the
                   Majority Banks it is capable of remedy, is not remedied

              (if any) by which (a) 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 (b) the
              amount of interest which in the opinion of the Agent (acting
              reasonably) would have been payable to the Agent on the last day
              of that Term in respect of a deposit in the currency of the amount

          received or recovered other than in accordance with Clause 22
          (Payments), then such Recovering Bank shall:

          24.1.1    notify the Agent of such receipt or recovery;

          24.1.2    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 22.5 (Partial
                    Payments).

24.2      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 22.5
          (Partial Payments).

24.3      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 24.2
          (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.

24.4      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:

          24.4.1    each party which has received a share of such Sharing
                    Payment pursuant to Clause 24.2 (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

          24.4.2    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.

24.5      Exception
          This Clause 24 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.

                                     -52-

24.6    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.

25.     THE AGENT, THE ARRANGER AND THE BANKS

25.1    Appointment of the Agent
        The Arranger and each of the Banks hereby appoints the Agent to act as
        its agent in connection herewith and authorises the Agent to exercise
        such rights, powers, authorities and discretions as are specifically
        delegated to the Agent by the terms hereof together with all such
        rights, powers, authorities and discretions as are reasonably incidental
        thereto.

25.2    Agent's Discretions
        The Agent may:

        25.2.1    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;

        25.2.2    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 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;

        25.2.3    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;

        25.2.4    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;

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

                                     -53-
<PAGE>

          25.2.6    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;

          25.2.7    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

          25.2.8    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.

25.3      Agent's Obligations
          The Agent shall:

          25.3.1    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);

          25.3.2    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;

          25.3.3    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 Arranger and the Banks; and

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

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

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

          25.4.1    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

                                     -54-
<PAGE>

                    of or default by an Obligor of or under its obligations
                    under the Finance Documents;

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

          25.4.3    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 Arranger, 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;

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

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

25.5      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 20.1 (Company's Indemnity).

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

          25.6.1    for the adequacy, accuracy and/or completeness of any
                    information supplied by the Agent or the Arranger, 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;

          25.6.2    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

          25.6.3    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.

                                     -55-
<PAGE>

        Accordingly, neither the Agent nor the Arranger 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.

25.7    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 Arranger
        any claim it might have against any of them in respect of the matters
        referred to in Clause 25.6 (Exclusion of Liabilities).

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

25.9    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
        25.

25.10   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.

25.11   Successor Agent
        If the Agent gives notice of its resignation pursuant to Clause 25.9
        (Resignation) or it is removed pursuant to Clause 25.10 (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.

25.12   Rights and Obligations
        If a successor to the Agent is appointed under the provisions of Clause
        25.11 (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 25 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.

<PAGE>

25.13   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:

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

        25.13.2   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;

        25.13.3   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

        25.13.4   the adequacy, accuracy and/or completeness of any information
                  provided by the Agent or the Arranger, 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 Arranger that
        it has not relied on and will not hereafter rely on the Agent and the
        Arranger or either of them in respect of any of these matters.

25.14   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 25, 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.

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

        25.15.1   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;

        25.15.2   the benefit of all representations, covenants, guarantees,
                  indemnities and other contractual provisions given in favour
                  of the Agent (other than any such

                                     -57-
<PAGE>

                  benefits given to the Agent solely for its own benefit) by or
                  pursuant to the Finance Documents (other than this Agreement);
                  and

        25.15.3   all proceeds of the security referred to in sub-clause 25.15.1
                  above and of the enforcement of the benefits referred to in
                  25.15.2 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 25.

25.16   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:

        25.16.1   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;

        25.16.2   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

<PAGE>

               Value to the extent necessary to ensure that the Required Value
               of the Charged Portfolio is of 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:

                Institution; and

        as a Bank (whereupon such assignee shall become a party hereto as a
        "Bank"), the Agent, the Arranger, 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.

                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 26.5 as "discharged
                rights and obligations");

                assume obligations towards one another and/or acquire rights

        26.5.3  the Agent, the Arranger, the Security Trustee, the Co-Arrangers,
                such Transferee and the other Banks shall acquire the same
                rights and benefits and assume the same obligations between

                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

                further obligations to each other under the Finance Documents;

               this Agreement to a fixed amount or fixed amounts in a national
               currency unit to be paid to or by the Agent shall be replaced by

                       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

                                     -89-
<PAGE>

                          Fees Regulations) and expressed in pounds per
                          (pound)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 2000 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.

        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 which
        has not been remedied or waived under the Agreement, you shall have and
        be entitled without prior notice to us to exercise the power to sell or
        otherwise dispose of, for any consideration (whether payable immediately
        or by instalments) as you shall think fit, the whole or any part of the
        Charged Portfolio and may (without prejudice to any right which you may
        have under any other provision hereof) treat such part of the Charged
        Portfolio as consists of money as if it were the proceeds of such sale
        or other disposal. You shall be entitled to apply the proceeds of such
        sale or other disposal in paying the costs of such sale or other
        disposal and (subject to the rights or claims of any person entitled in
        priority to you) in or towards the discharge of the Obligations, the
        balance (if any) to be paid to us or other persons entitled thereto.
        Such power of sale or other

                                     -98-
<PAGE>

        disposal shall operate as a variation and extension of the statutory
        power of sale under Section 101 of the Law of Property Act 1925.

8.2     The restriction contained in Section 103 of the Law of Property Act 1925
        on the exercise of the statutory power of sale shall not apply to any
        exercise by you of your power of sale or other disposal which shall
        arise, as shall the statutory power under the said Section 101 of
        appointing a receiver of the Charged Portfolio or the income thereof,
        immediately upon the occurrence of an Event of Default which is
        continuing and which has not been remedied or waived as is referred to
        in Clause 8.1. In favour of a purchaser of all or any part of the
        Charged Portfolio, a certificate in writing by your officer or agent
        that either or both of such powers has arisen and is exercisable shall
        be conclusive evidence of that fact.

8.3     Without limitation to the generality of your rights and remedies as set
        forth in Clause 8.1, you may at any time without prior notice to us:-

        8.3.1     after an Event of Default has occurred which is continuing and
                  which has not been remedied or waived, exercise any or all of
                  your rights under or pursuant to the Custodian's Undertaking;
                  and

        8.3.2     if any or all of the component parts of the Charged Portfolio
                  (the "Ineligible Property") delivered, transferred or assigned
                  to you under or pursuant to the Custodian's Undertaking do not
                  satisfy the Security Trustee's Requirements,

        then you may (but shall not be obliged to):

        (a)       convert for our account and at our sole risk all or any part
                  of the Ineligible Property into property which does satisfy
                  all or any of the Security Trustee's Requirements in such
                  manner as you in your sole discretion (acting reasonably) may
                  determine to be appropriate; and/or

        (b)       sell for our account and at our sole risk all or any part of
                  the Ineligible Property in return for payment of such currency
                  or currencies as you in your sole discretion (acting
                  reasonably) determine to be appropriate and pay the same to an
                  account or accounts opened or maintained by you for that
                  purpose pursuant to Clause 13.2.

9.      POWER OF ATTORNEY

        We hereby by way of security for the performance of our obligations
        hereunder irrevocably (within the meaning of Section 4 of the Powers of
        Attorney Act 1971) appoint you to be our attorney and in our name and on
        our behalf and as our act and deed after an Event of Default has
        occurred which is continuing and which has not been remedied or waived,
        to sign, seal, execute, deliver, perfect and do all deeds, instruments,
        mortgages and things as may be, or as you may consider to be, requisite
        for carrying out any obligations imposed on us under Clause 5, or for
        enabling you to exercise your power(s) of sale or other disposal or
        conversion referred to in Clause 8 or for carrying into effect any such
        sale or other disposal or conversion made under

                                     -99-
<PAGE>

        such power(s) by 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 the Charged Portfolio. We hereby undertake to ratify and
        confirm all things done and documents executed by you in the exercise of
        the power of attorney conferred by this Clause.

11.1    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.

11.2    This Charge Agreement shall remain in full force and effect as a
        continuing security unless and until you discharge it.

11.3    Nothing contained in this Charge Agreement is intended to, or shall

        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.

12.     REMEDIES, TIME OR INDULGENCE

12.1    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.

12.2    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.

12.3    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 us to you.

13.     ACCOUNTS

                                     -100-
<PAGE>

13.1    If you shall at any time receive notice of any subsequent mortgage,
        assignment, charge or other interest affecting all or any part of the
        Charged Portfolio you may open a new account or accounts for us in your
        books. If you do not do so, then (unless you give to us express written
        notice to the contrary) as from the time of receipt of such notice by
        you, all payments made by us to you shall in the absence of any express
        appropriation by you to the contrary be treated as having been credited
        to a new account of ours and not as having been applied in reduction of
        the Obligations at the time when you received the notice.

13.2    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.

13.3    In case you shall have more than one account for us in your books you
        may at any time after making any demand for payment or other discharge
        of any of the Obligations, and for so long as all the Obligations remain
        unpaid, or after you shall have received notice of any subsequent charge
        or other interest affecting all or any part of the Charged Portfolio,
        and without prior notice in that behalf, forthwith transfer all or any
        part of any balance standing to the credit of any such account to any
        other such account which may be in debit.

14.     CURRENCY

14.1    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 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.

14.2    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.

15.     COSTS, CHARGES AND EXPENSES

        All your reasonable costs, charges and expenses incurred in the exercise
        of any Security Trustee Right, or in connection with the execution of or
        otherwise in relation to this Charge Agreement and all your costs,
        charges and expenses incurred in connection with the perfection or
        enforcement of the security hereby constituted or any other security
        held by you for the Obligations or any guarantee to you in respect
        thereof, shall be reimbursed to you by us on demand on a full indemnity
        basis together with interest from the date of the same having been
        incurred (or from the date of

                                     -101-
<PAGE>

        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.

16.     LAW AND JURISDICTION

        This Charge Agreement shall be governed by English law and for your
        benefit we hereby irrevocably submit to the jurisdiction of the English
        courts.

17.     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.

2.   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.

3.   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.

4.   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 one Business Day of such day) of the trades and transactions
     processed.

5.   The Custodian shall be entitled to process trades as it may be directed to
     do so under the terms of its custodial agreement with the Chargor 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
     of other securities save that transfers can be made (i) to the Security
     Trustee in accordance with the terms of this undertaking or (ii) to any
     person with the Security Trustee's prior written consent or (iii) in
     respect of any part of the Charged Portfolio representing an excess over
     the Required Value, to the Chargor or as it may direct, which excess will
     be determined by the Security Trustee on the date of the request from the
     Chargor.

6.   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 up to the Required Value 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.

7.   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 Chargor with the Custodian with any reasonable fees or
     commissions due and owing by the Chargor to the Custodian in respect of the
     Charged Portfolio or part thereof or to settle any reasonable bank charges
     due and owing by the 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.
