                  Revolving Facility Limit.

            5.3.2 Subject always to the other terms of this Agreement, a
                  Drawdown Notice shall be irrevocable and the Company shall be
                  obliged to borrow in accordance with its terms.

            5.3.3 Advances shall be made only on a Business Day.

5.4   Participations and Payments

5.4.1 Subject always to the other terms of this Agreement (including Clause
      5.6), each Bank acting through its Lending Office, agrees to contribute
      its Participation in each Advance, in, subject to Clause 7, the currency
      of such Advance, the amount of its Participation being that proportion
      which its unutilised Term Loan Commitment or Revolving Loan Commitment, as
      the case may be, bears to the unutilised part of the Total Term Loan
      Commitments or the Total Revolving Loan Commitments, as the case may be,
      on the relative Drawdown Date.

5.4.2 Subject to Clause 5.6, each Bank shall on the relative Drawdown Date
      advance to the Company its Participation in the requested Advance by
      making available to the




      Agent to such account as the Agent may have previously specified for this
      purpose, not later than 11.00 am. (London time) (or 11.00a.m. local time
      in the principal financial centre of the relevant Alternative Currency) on
      such date in immediately available funds, an amount in the relevant
      currency equal to such Participation and, subject to receiving the same,
      the Agent will advance such amount to the Company or, as its directs, as
      requested in the relative Drawdown Notice.

5.5   Drawdown Indemnity

      If for any reason any Advance (or part thereof) is not made to the Company
      on a Drawdown Date in accordance with the relative Drawdown Notice, the
      Company shall indemnify each of the Banks in accordance with Clause 12.3.

5.6   Initial Funding

5.6.1 This Clause 5.6 applies notwithstanding any other provision hereof.

5.6.2 As at the date of this Agreement, there are advances (the "Existing
      Advances") outstanding under those of the Existing Facilities referred to
      in Clauses 4.1.1 (a)-(c) inclusive which mature on, respectively, 15th
      January 1996, 3rd, 4th and 9th April 1996. The Existing Advances are to be
      refinanced with the proceeds of the Term Advance of US$40,000,000 and the
      first Revolving Advances in an aggregate amount up to the Revolving
      Facility Limit (together the "First Advances"). On the Refinancing Date,
      the Existing Advances shall be deemed to be refinanced with the proceeds
      of the First Advances by the Banks on the basis that each Bank refinances
      that part of the Existing Advances owed to such Bank and that the Interest
      Periods relating to such Bank's Participation in the First Advances have
      Interest Dates which are the same as those parts of the Existing Advances
      which it refinances.

5.6.3 In respect of any part of the First Advances with an Interest Date of 3rd
      or 4th April 1996, on such date, that part shall be deemed to be
      refinanced with a Participation of the relevant Banks in an Advance with a
      Interest Period expiring on 9th April 1996.

5.6.4 In respect of any part (the "Short Term Part") of the First Advances with
      a corresponding Interest Date of 15th January 1996, on such date, the
      Short Term Part shall be deemed to be refinanced with a Participation of
      the relevant Banks in an Advance with an Interest Period expiring on 31st
      March 1996. On 31st March 1996 the Short Term Part, to the extent not
      applied in repayment and permanent reduction, of the Facilities shall be
      deemed to be refinanced with a Participation of the relevant Banks in an
      Advance with an Interest Period expiring on 30th June 1996.

5.6.5 The provisions of Clauses 5.6.2, 5.6.3 and 5.6.4 shall have automatic
      effect and shall not require the service of any Drawdown Notice by the
      Company.

5.6.6 On and from 9th April 1996 all Advances, other than those forming all or
      part of the Short Term Part, shall be made and funded in accordance with
      the other terms of this Agreement.




5.6.7 If, prior to 30th June 1996, the Agent serves notice under Clause 15.1,
      the Banks shall promptly make such payments amongst themselves in order to
      make their Participations in Advances what they would have been but for
      Clauses 5.6.2 to 5.6.6 inclusive on the basis of the then current exchange
      rates.

5.6.8 Prior to 30th June 1996, all prepayments of the Loans shall be applied as
      they would have been if the relevant prepayment was made after 30th June
      1996.

5.6.9 Interest on the First Advances (other than the Short Term Part) at the
      rate currently applicable to the Existing Advances shall be paid on 5th
      January 1996 and on the Interest Dates relating thereto and shall be
      deemed to have accrued from the date on which the interest periods current
      at the date hereof for the Existing Advances commenced.

5.6.10 Any commitment commission accrued but unpaid on undrawn amounts under the
      Existing Facilities shall be paid by the Company on the date or dates it
      would have been payable pursuant to the terms of the Existing Facilities.

5.6.11 Each of the Banks hereby authorise, and instruct the Facility Agent, to
      transfer on the Refinancing Date, to the credit of any current account of
      the Company which forms part of the Overdraft Facility, any monies
      standing to the credit of a suspense account held with the Facility Agent
      in connection with the Existing Facilities.


6.    THE OVERDRAFT FACILITY AND THE UNCOMMITTED ENGAGEMENTS FACILITY

6.1.1 The Overdraft Facility is made available to the Borrowers in accordance
      with this Clause 6 and the General Terms.

6.1.2 No utilisation of the Overdraft Facility may be made prior to the
      Refinancing Date and on the Refinancing Date all amounts outstanding under
      the overdraft facilities forming part of the Existing Facilities shall be
      deemed to have been made available under the Overdraft Facility and shall
      automatically be treated thereafter as outstanding under the Overdraft
      Facility.

6.1.3 A Borrower wishing to utilise the Overdraft Facility shall complete such
      mandate and other documents as the relevant Bank shall reasonably require.

6.1.4 The Overdraft Facility shall cease to be available on the Final Repayment

      its Overdraft Commitment, agrees to make the Overdraft Facility available

      of overdraft on usual banking terms PROVIDED THAT, subject to Clause
      6.2.2, no demand for repayment shall be made in respect thereof other than
      in accordance with Clause 15.2.

6.2.2 Notwithstanding Clause 6.2.1, as and from any date on which the Overdraft
      Outstandings exceed the Overdraft Facility Limit all amounts outstanding
      under the Overdraft Facility shall automatically become repayable on
      demand made by the Bank which makes available the relevant overdraft under
      the Overdraft Facility.

6.2.3 No utilisation of the Overdraft Facility under Clause 6.2.1 shall be made
      if it would result in the amounts outstanding by way of overdraft under
      the Overdraft Outstandings exceeding the Overdraft Facility Limit.

6.2.4 For the avoidance of doubt, a Bank may, without liability, return cheques
      unpaid and reflise to honour direct debits, Bankers Automated Clearing
      System facilities, standing orders and any other payment orders if the
      payment of such items would result in a breach of Clause 6.2.3.

      Capital Bank shall not be obliged to issue, or enter into, any Engagement.

            expenses, losses and charges whatsoever in relation to or arising
            out of any Engagement entered into, or issued, at the request of
            such Borrower and such Borrower will pay the Working Capital Bank on
            demand the amount of all payments made (whether directly or by way
            of set-off, counterclaim or otherwise howsoever) and all losses,
            costs and expenses suffered or incurred from time to time by the
            Working Capital Bank under or by reason or in consequence of any
            such Engagement and any of the aforesaid indemnities relating
            thereto;

      (b)   save in the case of negligence, fraud or willful default on the part
            of the Working Capital Bank:




            (i)   the Working Capital Bank is hereby irrevocably authorised by
                  each Borrower to comply with the terms of any demand served or
                  purporting to be served on the Working Capital Bank pursuant
                  to any Engagement without any reference to, or lurther
                  authority from, any Borrower and without any enquiry by the
                  Working Capital Bank into the justificationfor such. demand or
                  the validity thereof; and


            (ii)  each Borrower further agrees that any payment which the
                  Working Capital Bank shall make in accordance or purporting to
                  be in accordance with such a demand shall be binding on each
                  Borrower and be accepted by such Borrower as conclusive and
                  binding evidence that the Working Capital Bank was liable to
                  comply with the terms of such demand and was liable to do so
                  in the manner and for the amount in which the Working Capital
                  Bank effected such compliance;

      (c)   save as specifically provided in Clause 6.3.5(b) the liability of
            each Borrower under this Clause 6.3.5 shall not be discharged,
            lessened or impaired by any time being given or by any thing being
            done or other circumstance whatsoever which, but for this provision,
            would or might operate to exonerate or discharge such Borrower; and

      (d)   the indemnity contained in this Clause 6.3.5 shall constitute and be
            a continuing security to the Working Capital Bank and the said
            indemnity shall extend to each Engagement as it may, from time to
            time, be varied, modified, amended or extended.

6.3.6 Each Borrower hereby agrees that it shall pay to the Working Capital Bank
      interest on the amount of each payment, loss, cost and expense made,
      suffered or incurred from time to time by the Working Capital Bank under
      or by reason or in consequence of any Engagement entered into or issued at
      the request of such Borrower and any of the indemnities contained in
      Clause 6.3.5 from and including the date upon which such payment, loss,
      cost or expense is made, suffered or incurred as aforesaid up to and
      including the date upon which payment or reimbursement of such amount is
      demanded from such Borrower. The amount of such interest shall be
      calculated in accordance with the provisions of Clause 8.3. For the
      avoidance of doubt, interest on sums demanded under the provisions of
      Clause 6.3.5 shall also accrue in accordance with Clause 8.3.

7.    AVAILABILITY OF ALTERNATIVE CURRENCIES

7.1   Non-Availability

      Bank that:




      (i)   it is reasonably unable to obtain sufficient funds necessary to
            find its Participation in such Advance in the ordinary course of
            business in the London Inter-Bank Market; or

      (ii)  central bank or other governmental authorisation in the country of
            the proposed Alternative Currency is required to permit its use by

            not been obtained or is not in full force and effect; or

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

      the Agent shall give notice to the Company to that effect before 10.30
      a.m.(London time) on the second Business Day prior to such Drawdown Date.

7.2   Effect of Notice

      (i)   the Margin from time to time;

      (ii)  LIBOR; and

8.2.2 The Company shall, subject to Clause 8.2.6, in each Drawdown Notice select
      the Interest Period of the Advance to which such Drawdown Notice relates.

8.2.3 In respect of Term Advances, interest shall be calculated by reference to
      successive Interest Periods. Each succeeding Interest Period relative to a
      Term Advance shall commence on the last day of the preceding Interest

      Date and if an Interest Period selected purports so to do, it shall
      nevertheless expire on the Final Repayment Date.

8.2.7 If the Company fails to select an Interest Period for an Advance, the
      Company shall, subject to Clause 8.2.6, be deemed to have selected an
      Interest Period of 3 months.

8.2.8 Any Interest Period which commences on the last Business Day in a month or
      on a Business Day for which there is no numerically corresponding day in
      the month in which that Interest Period is to end, shall (subject to
      Clause 8.2.6) end on the last Business Day in that later month.

      falls in the following month, on the immediately preceding Business Day.

8.3   Default Interest

      its due date, a Borrower shall pay default interest on such sum (or, as
      the case may be, the amount thereof for the time being due and unpaid) to
      the Agent for the account of the Agent and the Banks or the Working
      Capital Bank, as the case may be, from the due date to the date of actual
      payment in full calculated by reference to successive Interest Periods
      (each of such duration as the Agent may from time to time select




      and the first beginning on the relative due date) at the rate per annum
      being the aggregate of:

      (i)   1 per cent. per annum;

      (ii)  the Margin from time to time;

      (iii) LIBOR; and

      (iv)  in the case of sums denominated in Sterling, the Mandatory Liquid
            Asset Costs.

      8.3.2 So long as the default continues, such rate shall be recalculated in
            accordance with the provisions of this Clause 8.3 on the last day of
            each such Interest Period and unpaid interest then payable but
            unpaid under this Clause shall be compounded at the end of each
            Interest Period.

      8.4   Interest under the Overdraft Facility

      8.4.1 Interest on all amounts outstanding by way of overdraft under the
            Overdraft Facility shall accrue at the rate per annum which is the
            aggregate of:

            (i)   the Margin from time to time; and

            (ii)  the most recently published base rate of the Bank making
                  available the relevant overdraft.

      8.4.2 Interest under Clause 8.4.1 on amounts outstanding by way of
            overdraft shall be paid by the relevant Borrower to the Bank making
            available the relevant overdraft on such Bank's usual quarterly
            charging days and (if not such a quarterly charging day) the Final
            Repayment Date.

      8.4.3 Each Bank making available an overdraft under the Overdraft Facility
            is hereby authorised by each Borrower to debit all interest payable
            by such Borrower under this Clause 8.4 to the current account held
            by such Borrower with such Bank and such Bank shall notify such
            Borrower of the amount debited in accordance with the normal
            practice of such Bank.

      8.5   Engagements Commission

            Commission in respect of each Engagement entered into or issued
            under the Uncommitted Engagements Facility shall:

            (i)   accrue from day to day on the Engagement Amount of such
                  Engagement at a rate per annum equal to the higher of:

                  (a)   the Margin from time to time; and




                  (b)   the Working Capital Bank's standard charges for the
                        relevant Engagement;

            (ii)  be calculated on the basis of actual days elapsed and a 360
                  days' year in the case of an Engagement denominated in a
                  currency other than Sterling, but if such Engagement is
                  denominated in Sterling, a 365 days' year; and

            (iii) be paid in Sterling on the Working Capital Bank's normal
                  charging days for the relevant Engagement.

8.6   Calculation and Payment of Interest

8.6.1 Promptly following the beginning of each Interest Period and, in the
      circumstances of the Margin reducing, on the date on which such reduction
      becomes effective, the Agent will notify the relevant Borrower of the rate
      and amount of interest payable for such Interest Period (but in the case
      of such interest calculated under Clause 8.3, any such notification need
      not be made more frequently than weekly). Such notification shall set out
      in reasonable detail the basis of computation of the amount of interest so
      payable.

8.6.2 Interest due from a Borrower to any of the Agent, the Working Capital Bank
      and the Banks under this Agreement shall:

      (i)   accrue from day to day at the appropriate rate calculated under this
            Clause 8;

      (ii)  except as otherwise provided in this Agreement (and, in particular,
            Clauses 8.4 and 8.6.3), be paid by the relevant Borrower to the
            Agent for the account of the Banks or the Agent, as the case may be,
            in arrear on each Interest Date, save that in the case of any
            Interest Period which is for longer than 6 months, such Borrower
            shall pay interest 6 monthly in arrear and on the relative Interest
            Date;

      (iii) be calculated on the basis of the actual number of days elapsed and,
            in the case of Sterling, a 365 day year or, in the case of an
            Alternative Currency, a 360 day year or, if different, such number
            of days as is market practice for the relevant currency; and

      (iv)  be payable after as well as before judgment.

8.6.3 The Additional Margin, if any, shall be payable on 30th June 1996 to the
      Banks, pro rata to their Commitments.

8.7   Market Disruption

      If:

      (i)   no relevant rate appears on the Reuter Monitor Money Rates Service
            for the purposes of paragraph (a) in the definition of LIBOR and the
            Agent



            determines that at or about 11.00 a.m.(London time), in the case of
            Sterling, or, in the case of an Alternative Currency, 2 Business
            Days before, the first day of an Interest Period none of the
            Reference Banks is offering to leading banks in the London
            Inter-Bank Market deposits in Sterling or an Alternative Currency,
            as appropriate, for the required period; or

      (ii)  no relevant rate appears on the Reuter Monitor Money Rates Service
            for the purposes of paragraph (a) in the definition of LIBOR and
            before the close of business in London in the case of an Alternative
            Currency, 2 Business Days before, or in the case of Sterling, on the
            first day of an Interest Period the Agent has been notified by each
            of a group of Banks the aggregate of whose Commitments, as the case
            may be, is equal to at least 33 per cent. of the Term Loan
            Commitments or the Revolving Loan Commitments, as the case may be,
            that the rate at which such deposits are being so offered does not
            accurately reflect the cost to it of obtaining such deposits; or

      (iii) by reasons of circumstances generally affecting the London
            Inter-Bank Market, reasonable and adequate means do not exist for
            ascertaining LIBOR for any Advance for any relative Interest Period;

      then:

      (a)   the Agent shall promptly give notice to the Company in writing of
            such event (a "market disruption notice");

      (b)   the Agent and the Company shall discuss an alternative basis for
            calculating the relative rate of interest for the relative Advance
            (the "Affected Advance") on the basis that the net return to the

                  (1)   the Margin during such period;

                  (2)   the rate notified by each Bank to the Agent to be the

      maintain its Commitment or its Participation, or otherwise give effect to
      all or any of its obligations as contemplated by this Agreement, the
      relative Bank shall promptly, upon becoming aware of the same, inform the
      Agent and the Agent shall forthwith inform the Borrower to that effect,
      whereupon such Bank's Commitment shall forthwith be reduced to zero and
      its obligation to permit its Participation in the Advances to remain
      outstanding shall forthwith terminate and the Borrower shall, within such

      prohibition and such Bank and the Agent will enter into negotiations in
      good faith with the Borrower with a view to finding a means of avoiding or
      mitigating the effects of such unlawfulness or prohibition including the
      transfer of the Lending Office to another jurisdiction or the transfer of

                  applies of the Bank of England, the European Community or of
                  any other governmental, monetary or other authority (whether
                  in the United Kingdom or elsewhere) having jurisdiction over
                  the relative Bank; or

      (b)   any change in the interpretation or application thereof,

      shall:

            (i)   subject any Bank to any Tax Liability in connection with its
                  Commitment or Participation in the Facilities or any part
                  thereof or in connection with any of the Financing Documents
                  other than Tax on the Overall Net Income of any Bank; or

            (ii)  change the basis or timing of Taxation of any Bank in respect
                  of payments of principal, interest or any other amount paid,
                  payable or to become payable in connection with its Commitment
                  or Participation in the Facilities or in connection with any
                  of the Financing Documents (or the treatment for Taxation
                  purposes of such payments); or

            (iii) change the basis or timing of the treatment of any of the
                  Banks for Taxation purposes in respect of any principal,
                  interest or other amounts paid, payable or to become payable
                  by such Bank on, or otherwise in respect of, deposits or loans
                  from third parties used to effect or maintain its

                  be fully compensated under Clause 8.1(c); or

            (v)   change the manner in which any of the Banks allocates capital
                  resources to its obligations under or in relation to the
                  Facilities so that it is unable to obtain the rate of return
                  on its overall capital which it would have been able to obtain
                  but for any of its entering into, performing its obligations
                  and assuming or maintaining its Commitment or its
                  Participation in the Facilities;




                  and the result of any of the foregoing is either to increase
                  the cost to any of the Banks of making available its
                  Commitment or its Participation in the Facilities or any part
                  thereof or of carrying out any of the transactions provided
                  for or contemplated by any of the Financing Documents or to
                  reduce the amount of any payment received or receivable by
                  such Bank or to reduce its return from the Facilities, then
                  and in any such case:

                  (aa)  such Bank shall notify the Company and the Agent;

                  (bb)  the Company shall pay (as additional interest) from time
                        to time to such Bank for the account of such Bank within
                        5 Business Days of demand all amounts which such Bank
                        certifies (in a certificate which shall set out in
                        reasonable detail so far as is practicable the basis of
                        the computation of such amounts) to be necessary to
                        compensate such Bank for the additional cost or
                        reduction;

                  (cc)  without prejudice to the foregoing, each Bank confirms
                        that if it notifies the Company and the relative
                        Borrower as aforesaid such Bank shall take such steps as
                        such Bank considers reasonable to reduce or avoid the
                        additional cost or reduction including the transfer of
                        its Lending Office to another jurisdiction or the
                        transfer of its rights and obligations to another
                        financial institution and, if the Company so requests,
                        such Bank shall consult with the Company and the Agent
                        with a view to finding a means of reducing or avoiding
                        the additional cost or reduction PROVIDED THAT neither
                        such Bank nor the Agent shall be obliged to continue
                        such negotiations for a period of longer than 30 days;
                        and

                  (dd)  without prejudice to the Company's obligation to pay to
                        the relative Bank the due amount under this Clause 11.2,
                        the relative Borrower, may, at any time alter receipt of
                        such notification, so long as the circumstances giving

                        interest thereon (subject always to the provisions of
                        Clause 12.3). In such event, such Bank's Commitment
                        shall be reduced to zero.




                  Any of such notification and certification referred to in any
                  of paragraphs (aa) and (bb) of this Clause 11.2 may be made at

      on demand against any loss or expense (including any loss or expense
      sustained or incurred or to be sustained or incurred by any Bank in
      liquidating or employing




      deposits acquired or contracted for to effect or maintain its
      Participation in the Advances or the Overdraft Outstandings or any part
      thereof) which such Bank or the Working Capital Bank has sustained or
      incurred as a consequence of any of:

      (i)   an Advance not being made, following the service of a Drawdown
            Notice by reason of the non-fulfilment of any of the Conditions
            Precedent or otherwise (save as may arise as a result of the failure
            of such Bank to comply with its obligations hereunder);

      (ii)  a default by a Borrower on the payment on the due date of any sum
            due under this Agreement; and

      (iii) the repayment of the Term Loan or any Revolving Advance and/or the
            Overdraft Outstandings or the termination of the Facilities, in each
            case, pursuant to Clause 15.

12.3.2 If any prepayment or repayment of an Advance is made otherwise than on an
      Interest Date, the Company shall on demand pay to the Agent, for the
      account of the Banks, such additional amount as the Agent may certify is
      necessary to compensate the Banks or any of them for any loss or expense
      on account of funds borrowed, contracted for or utilised to fund the
      amounts so repaid or prepaid. Any certifications issued by the Agent
      pursuant to this Clause 12.3 shall be conclusive and binding on the
      Company save in the case of manifest error.

12.4  Grossing-Up

12.4.1 Subject to Clause 12.4.2, all sums payable by a Borrower to any of the
      Agents, the Working Capital Bank and the Banks pursuant to or in
      connection with any of the Financing Documents shall be paid in full
      without any set-off or counterclaim whatsoever and free and clear of all
      deductions or withholdings whatsoever save only as may be required by law.

12.4.2 If any deduction or withholding is required by law in respect of any
      payment due from a Borrower to any of the Agent, the Banks or the Working
      Capital Bank pursuant to or in connection with any of the Financing
      Documents, such Borrower shall:

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

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

      (c)   increase the payment in respect of which the deduction or
            withholding is required so that the net amount received by the
            relative payee after the deduction or withholding (and after taking
            account of any further deduction or withholding which is required
            to be made as a consequence of the increase) shall be equal to the
            amount which the relative payee




            would have been entitled to receive in the absence of any
            requirement to make any deductions or withholdings; and

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

12.4.3 If the Agent is obliged to make any deduction or withholding from any
      payment to any of the Banks (an "agency payment") which represents an
      amount or amounts received by the Agent from any Borrower under any of the
      Financing Documents, the Company shall pay directly to the relative Bank
      such sum (an "agency compensating sum") as will, after taking into account
      any deduction or withholding which the Company is obliged to make from the
      agency compensating sum, enable such Bank to receive, on the due date for
      payment of the agency payment, an amount equal to the agency payment which
      such Bank would have received in the absence of any obligation to make any
      deductions or withholdings.

12.4.4 A Borrower shall not be required to pay an additional amount under this
      Clause 12.4 if the relevant Bank either:

      (a)   is not at the date hereof a Qualifying Bank; or

      (b)   ceases after the date hereof to be a Qualifyng Bank otherwise than
            as a consequence of a change in any applicable law, regulation,
            practice, concession, regulatory requirement or request (whether or
            not having the force of law) of the Bank of England, the European
            Community or of any other governmental, monetary or other authority;

      and, in either case, the obligation to deduct or withhold would not have
      arisen if the relevant Bank had been a Qualifying Bank.

12.4.5(a)   If any of the Banks determines, in its absolute discretion, that it
            has received, realised, utilised and retained a Tax benefit by
            reason of any deduction or withholding in respect of which a
            Borrower has made an increased payment or paid an agency
            compensating sum under this Clause 12.4, such Bank shall, provided
            that the Agent and each Bank has received all amounts which are then
            due and payable by the obligors under any of the Financing
            Documents, pay to such Borrower (to the extent that such Bank can do
            so without prejudicing the amount of such benefit or repayment and
            the right of such Bank, to obtain any other benefit, relief or
            allowance which may be available to it) such amount, if any, as such
            Bank, in its absolute discretion shall determine, will leave such
            Bank in no worse position than it would have been in if the
            deduction or withholding had not been required PROVIDED THAT:

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




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

            (iii) if a Bank has made a payment to a Borrower pursuant to this
                  Clause 12.4.5 on account of any Tax benefit and it
                  subsequently transpires that such Bank did not receive that
                  Tax benefit, or received a lesser Tax benefit, such Borrower
                  shall, on demand, pay to such Bank such sum as the relative
                  Bank may determine as being necessary to restore its after-Tax
                  position to that which it would have been had no adjustment
                  under this Clause (iii) been necessary. Any sums payable by a
                  Borrower to a Bank under this Clause (iii) shall be subject to
                  the provisions of Clause 18.8.

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

12.5  Mitigation

      If, in respect of any Bank or the Working Capital Bank, circumstances
      arise which would, or would upon the giving of notice, result in an
      increase in the amount of any payment to be made to it or for its account
      pursuant to Clause 12.4 (Grossing up), then, without in any way limiting,
      reducing or otherwise qualifying the rights of such Bank or the Working
      Capital Bank, as the case may be, or the obligations of each Borrower
      under Clause 12.4 such Bank or the Working Capital Bank, as the case may
      be, shall promptly upon becoming aware of the same notify the Agent
      thereof and, in consultation with the Agent and the Company and to the
      extent that it can do so without prejudice to its own position, take
      reasonable steps to mitigate the effects of such circumstances including
      the transfer of its Lending Office.

12.6  Prepayment Right

      If the Company is required to make an increased payment for the account of
      a Bank under Clause 12.4.2 or 12.4.3 (but only so long as such requirement
      exists), subject to giving the Agent and such Bank not less than 10 days'
      prior written notice (which shall be irrevocable), the Company may prepay
      such Bank's Participation in the Advances together with accrued interest
      thereon PROVIDED THAT any such prepayment shall be subject to the
      provisions of Clause 12.3. In such circumstances, the Commitment of the
      relevant Bank will be reduced to zero.

12.7  Accounts

      Each Bank shall maintain in accordance with its usual practice an account
      or accounts, which account or accounts shall, in the absence of manifest
      error, as between the Borrowers and such Bank be conclusive evidence of
      the amounts from




      time to time advanced by, owing to, paid and repaid to such Bank under
      this Agreement.

12.8  Borrower's Payments

12.8.1 The Agent may assume that a Borrower will make all payments due under
      this Agreement on the due date and the Agent may, in reliance
      upon such assumption, make available to each Bank on any payment
      date an amount equal to such Bank's pro-rata share of such assumed
      payment.

12.8.2 If a Borrower does not in fact make such payment to the Agent, each Bank
      shall forthwith on demand by the Agent repay to the Agent the amount made
      available to such Bank (together with interest thereon at the rate
      determined by the Agent as being its cost of funding such payment).

12.9  Banks' Payments

12.9.1 The Agent may assume that each Bank has made its Participation in an
      Advance available to the Agent on the relative Drawdown Date and the Agent
      may in reliance upon such assumption, make available to the Company a
      corresponding amount.

12.9.2 If such corresponding amount is not in fact made available to the Agent
      by such Bank, the Agent shall be entitled to recover such corresponding
      amount (together with interest thereon at the rate determined by the Agent
      as being its cost of funds in the circumstances) on demand from the
      Company.

12.9.3 Where the Agent has made available an amount to the Company in reliance
      upon the assumption contained in Clause 12.9.1 but a Bank has not made its
      Participation in the relevant Advance available to the Agent then, unless
      that Bank notified the Agent in writing prior to the relevant Drawdown
      Date that it would not be making its Participation in such Advance
      available, that Bank shall:

      (a)   if the Company does not refund the corresponding amount to the Agent
            within 3 Business Days, reimburse the Agent for such amount
            (together with interest thereon at the rate determined by the Agent
            as being its cost of funds in the circumstances) on demand; and

      (b)   indemnify the Agent from and against all losses, costs, charges and
            expenses which the Agent may incur or sustain by reason of that Bank
            not having made its Participation in the relevant Advance available.

12.10 Appropriation

      If a Borrower shall pay a sum in relation to the Facilities which is less
      than the total amount due and payable by it under this Agreement on the
      day on which such sum is paid such Borrower hereby waives any rights it
      may have to make any appropriation thereof as between any amounts so due
      and payable and the sum so paid shall be applied in or towards
      satisfaction of principal, interest, fees and other sums which are due or
      overdue for payment on that day in such order as the Majority Banks may




      determine PROVIDED THAT each Bank shail receive its pro rata share of any
      such sum.

12.11 Currency of Account

      All payments to be made by the Company in respect of an Advance, whether
      of interest or principal, shall be made in the currency in which such
      Advance is denominated. All payments to be made under any indemnity or
      reimbursement provision of this Agreement relating to costs, losses and
      expenses shall be paid in the currency in which the relative costs, losses
      or expenses were incurred.

      Creditors by notice to the Company




      cancel the Term Loan Facility and/or the Revolving Loan Facility and/or
      the Overdraft Facility in whole or in part and:

      (a)   require the Borrowers immediately to repay the Term Loan, the
            Revolving Loan and the Overdraft Outstanding together with accrued
            interest thereon and immediately to pay all other sums payable under
            this Agreement, whereupon the same shall become immediately due and

      (b)   place the Term Loan, the Revolving Loan and all overdrafts made

            demand made by the Agent on the instructions of the Majority
            Creditors.

      Upon the service of any such notice by the Agent the Banks' obligations
      shall be terminated and each of the Banks' Commitments shall be cancelled
      and reduced to zero.

15.2.2 Forthwith upon the Agent serving notice under Clause 15.2.1, each
      Borrower shall in respect of each Engagement entered into or issues at its
      request:

      (i)   use its best endeavours to procure the release of the Working
            Capital Bank from, such Engagement; and

      (ii)  without prejudice to (i) above, pay to the credit of such account as
            the working Capital Bank issuing such Engagement shall stipulate an
            amount equal to the maximum actual and contingent liabilities of the
            Working Capital Bank under such Engagement and charge the same to
            the Working Capital Bank on such terms as the Working Capital Bank
            may stipulate.

16.   SET-OFF AND PRO RATA PAYMENTS

16.1  Set-Off

      Each Borrower hereby authorises each of the Agent, the Banks and the
      Working Capital Bank to apply any credit balance on any account of such
      Borrower with any of the Agent, the Banks and the Working Capital Bank in
      satisfaction of any sum due and payable from such Borrower pursuant to the
      terms of the Financial Documents. For this purpose each of the Agent, the
      Banks and the Working Capital Bank is authorised to purchase at its spot
      rate of exchange with the monies standing to the credit of any such
      account such other currencies as may be necessary to effect such
      application.

16.2  Pro Rata Sharing

16.2.1 If any Bank (the "Sharing Bank") shall at any time obtain (whether by way
      of voluntary or involuntary payment right of set-off, or otherwise) a
      proportion in




      respect of its Participation in the Advances which is greater than the
      proportion obtained by the Bank or Banks respectively obtaining the
      smallest proportion of its Participation in the Advances, including a nil
      receipt, (the amount so obtained by the Sharing Bank which represents such
      excess being herein called "the excess amount")
      then:

      (i)   the Sharing Bank shall promptly pay to the Agent, for the account of
            the Banks, an amount equal to the excess amount, whereupon the Agent
            shall notify the Company of such amount and its receipt by the
            Agent;

      (ii)  the Agent shall treat such payment as if it were a payment by the
            Borrowers on account of sums owned to the Banks; and

      (iii) as between the Company and the Sharing Bank the excess amount shall
            be treated as not having been paid, while as between the Company and
            each Bank it shall be treated as having been paid to the extent any
            monies are received by such Bank.

      If, because of the liquidation of the Company, or for any other reason
      affecting the Company, the provisions of paragraph (iii) above cannot be
      given effect to as between the Banks on the one hand and the Company on
      the other hand then, as between the Banks, the Sharing Bank shall be
      treated as having purchased from each other Bank an amount of the
      Participations of that Bank in Advances which is equal to that part of the
      excess amount which is paid to that Bank and the Sharing Bank shall,
      accordingly, be entitled to receive all dividends and other payments
      received by that Bank in respect of such Participations, as the case may
      be, deemed to have been purchased by it.

16.2.2 Each Bank shall forthwith notify the Agent of any such receipt or
      recovery by it other than by payment through the Agent.

16.2.3 If any excess amount subsequently has to be wholly or partly refunded to
      the Company by any Sharing Bank which has paid an amount equal thereto the
      Agent under Clause 16.2.1, each Bank to which any part of that amount was
      distributed shall on request from the Sharing Bank repay to the Sharing
      Bank such Bank's pro rata share of the amount which has to be so refunded
      by the Sharing Bank. Each Bank shall on request supply to the Agent such
      information as the Agent may from time to time request for the purpose of
      this Clause 16.2. Notwithstanding the foregoing provisions of this Clause
      16.2, no Sharing Bank shall be obliged to share any excess amount which it
      receives or recovers pursuant to legal proceedings taken by it to recover
      any sums owing to it under this Agreement with any other party which has a
      legal right to, but does not, either join in such proceedings or commence
      and diligently pursue separate proceedings to enforce its rights in the
      same or another court, unless the proceedings instituted by the Sharing
      Bank are instituted by it without prior notice having been given to such
      party through the Agent and an opportunity to such party to join in such
      proceedings.

16.2.4 Nothing in this Agreement shall oblige the Agent or any Bank to apply any
      credit balance or other benefit received from the Borrower against the
      liabilities of the




Borrower under this Agreement in priority to any other liabilities of the
Borrower to the Agent or that Bank.

                associated company of a member of the Group or any associated
                company of a member of the Group without regard to the effect of
                exercising or omitting to exercise its discretions, authorities,
                rights, powers and duties in such capacity in the interests of
                the Banks and may act or omit to act in such capacity as freely

                or any associated company of a member of the Group (and, in each
                case, may do so without liability to account).

17.1.4  For so long as Lloyds Bank Plc is the Agent, the Capital Markets Group
        of Lloyds Bank Plc shall be treated as a separate entity from any other
        of the divisions of the Agent or its Subsidiaries and, notwithstanding
        the generality of the foregoing, in the event that any of the Agent's
        divisions (including its Capital Market Group) or similar units or
        Subsidiaries should act for any member of the Group in any a capacity
        (whether as bankers or otherwise) in relation to any other matter, any
        information given by any member of the Group to such divisions, similar
        units or Subsidiaries





        shall be treated as confidential and the Agent shall, as between itself
        and the Banks, not be obliged to disclose the same to any Bank or any
        other person.

17.1.5  For the purposes of this Agreement, the Agent shall be deemed not to
        have any actual knowledge or actual notice of the contents of any
        information obtained by it or supplied to it by or on behalf of any
        member of the Group other than the contents of information obtained by
        or supplied to it as Agent for the Banks pursuant to or in connection
        with this Agreement.

17.2    Payments and Information Received

        The Agent will promptly account to the Lending Office of each Bank for
        such Bank's due proportion of all sums received by the Agent for such
        Bank's account, whether by way of repayment or prepayment of principal
        or payment of interest, fees or otherwise. The Agent shall provide the
        Banks with all information and copies of all notices which by the terms
        of this Agreement are to be provided or given to the Banks. The Agent
        may retain for its own use and benefit (and shall not be liable to
        account to any of the Banks for all or any part of) any sums received by
        it by way of agency or management or arrangement fees or by way of
        reimbursements of expenses incurred by it.

17.3    Defaults

        The Agent shall not be obliged to take any steps to ascertain whether
        any Default (other than a default in repayment of principal or in
        payment of interest, fees or other sums due pursuant to this Agreement)
        or Default Occurrence has happened or exists and, until the Agent shall
        have received express notice to the contrary from a Borrower or any
        Bank, the Agent shall be entitled to assume that no Default (other than
        as aforesaid) or Default Occurrence has happened or exists. Upon receipt
        of such notice the Agent shall promptly inform the Banks.

17.4    Assumptions

        The Agent shall be entitled to rely on any communication or document
        believed by it to be genuine and correct and to have been communicated
        or signed by the person by whom it purports to be communicated or signed
        and shall not be liable to any of the parties to this Agreement for any
        of the consequences of such reliance.

17.5    Legal Proceedings

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





17.6    No Liability

        Neither the Agent nor any of its directors, employees or agents shall be
        liable for any action taken or omitted to be taken by it or any of them
        under or in connection with the Financing Documents unless caused by its
        or their gross negligence or wilful misconduct. The Agent shall not be
        responsible for any statements, representations or warranties in this
        the Financing Documents or for any information supplied or provided or
        hereafter to be supplied or provided to any of the Banks and the Working
        Capital Bank by the Agent, in respect of a Borrower or any other person
        or for any other matter relating to the Facilities or the Financing
        Documents or for the execution, effectiveness, genuineness, validity,
        enforceability or sufficiency of such documents or any of the other
        documents referred to herein or therein or for the recoverability of all
        or any of the Loans or any of the other sums to become due and payable
        pursuant hereto.

17.7    Credit Decisions

17.7.1  Each Bank and the Working Capital Bank acknowledges that it has,
        independently and without reliance on the Agent and based on such
        documents and information as it deemed appropriate, made its own
        analysis of the transaction reached its own decision to enter into, this
        Agreement and made its own investigation of the financial condition and
        affairs of the Borrowers and its own appraisal of the creditworthiness
        of the Borrowers.

17.1.2  Save as specifically provided herein, the Agent shall not be under nay
        duty or obligation, either initially or on a continuing basis, to
        provide any Bank or the Working Capital Bank with any credit information
        or other information with respect to the financial condition of the
        Company or the Borrower of which is otherwise relevant to the
        Facilities.

17.7.3  Each Bank and the Working Capital Bank further acknowledges and confirms
        that it will, independently and without reliance on the Agent and based
        on such documents and information as it shall deem appropriate at the
        time, make its own decisions in taking or not taking action under the
        Financing Documents.

17.8    Advisers

        The Agent shall be entitled to obtain and rely on the advice of any
        professional advisers selected by it given in connection with the
        Financing Documents or any of the matters contemplated hereby or
        thereby, and shall not be liable to any of the Banks and the Working
        Capital Bank for any of the consequences of such reliance.

17.9    Relationship with Banks

17.9.1  In performing its functions and duties under this Agreement, the Agent
        shall act solely as the agent for the Banks and shall not assume or be
        deemed to have assumed any obligation as agent or trustee for, or any
        relationship of agency or trust with or the Borrowers.





17.9.2  Neither the Agent nor any Bank nor the Working Capital Bank shall be
        under any liability or responsibility of any kind to the Borrowers or
        any of the other Banks arising out of or in relation to any failure or
        delay in performance or breach by an other Bank or Banks and the Working
        Capital Bank or, as the case may be, a Borrower of any of its or their
        respective obligations pursuant to the Financing Documents.

17.10   Agent's position as a Bank

        With respect to its own Participation in the Loans, the Agent shall have
        the same rights and powers under and in respect of the Financing
        Documents as though it were not also acting as agent and/or trustee for
        the Banks. The Agent may, without liability to account, accept deposits
        from, lend money to and generally engage in any kind of banking or trust
        business with or for any Borrower as if it were not the agent or the
        trustee for the Banks.

17.11   Indemnity

        Each of the Banks agrees to indemnify the Agent (to the extent not
        reimbursed by the Borrower) rateably according to the Banks' respective
        Commitments from and against any and all liabilities, obligations,
        losses, damages, penalties, actions, judgments, suits, costs, expenses
        and disbursements of any kind or nature whatsoever (except in respect of
        any agency, management or other fee due to the Agent) which may be
        imposed on, incurred by or asserted against the Agent in its capacity as
        agent for the Banks or in any way relating to or arising out of the
        Financing Documents or any action taken or omitted by the Agent in
        enforcing or preserving the rights of the Banks under the Financing
        Documents, provided that no Bank shall be liable for any portion of such
        liabilities, obligations, losses, damages, penalties, actions,
        judgments, suits, costs, expenses or disbursements resulting from the
        Agent's gross negligence or wilful misconduct.

17.12   Resignation

17.12.1 Subject to the appointment and acceptance of a successor Agent as
        provided below, the Agent may resign at any time by giving to the
        Company and each of the Banks not less than 60 days' notice of its
        intention to do so. Upon receipt of such notice of resignation the Banks
        shall appoint as successor Agent any bank or financial institution
        selected by the Company and the Majority Banks which is willing and able
        to act as such agent for the Banks.

17.12.2 If no such successor Agent selected by the Company and the Majority
        Banks shall have accepted such appointment within 20 days after the
        Agent's giving of notice of resignation then the Majority Banks after
        consultation with the Company shall have the right to appoint such a
        successor Agent.

17.12.3 If no such successor Agent shall have been so appointed by the Majority
        Banks and shall have accepted such appointment within 40 days after the
        Agent's giving of notice of resignation then the resigning Agent may,
        after consultation with the 





        Company, appoint as its successor any reputable and experience bank or
        other financial institution with an office in London.

17.12.4 Any such appointment shall take effect upon notice thereof (which notice
        shall specify the bank in London to which payments shall be made
        thereafter) being given to the Company and each Bank. Thereafter, the
        resigning Agent shall be discharged from any further obligation under
        the Financing Documents and its successor and each of the other parties
        hereto and thereto shall have the same rights and obligations inter se
        as they would have had if such success had been a party to the Financing
        Documents in place of the resigning Agent. The resigning Agent shall
        make over to its successor all such records as its successor requires to
        carry out its duties.

17.13   Change of Office

        The Agent may from time to time in its sole discretion by written notice
        to the Company and each Bank designate a different office in the United
        Kingdom from which its duties as the Agent will thereafter be performed.

17.14   Scope of Duties

        The Agent may (except where the same is required by the express
        provisions of this Agreement to be authorised by all the Banks or the
        Majority Creditors) grant waivers, vary the terms of the Financing
        Documents and do or omit to do all such acts and things in connection
        therewith as may be authorised in writing by the Majority Banks. Any
        such waiver, variation, act or omission so authorised and effected by
        the Agent shall be binding on all the Banks and the Agent shall be under
        no liability whatsoever in respect of any such waiver, consent,
        variation, act or omission. Except with the prior written agreement of
        all the Banks, nothing in this Clause shall authorise (as between the
        Agent and the Banks) (i) any change in the rate at which any interest or
        commission is payable under this Agreement, (ii) any extension of the
        date for, or alteration in the amount or currency of, the payment of any
        principal, interest, fees or any other amount payable under this
        Agreement, (iii) "Majority Banks" in Clause 1.1, (v) any variation of
        Clause 8, 9 or 15 and this Clause 17 or (vi) any provision of this
        Agreement which requires the consent of all the Banks.

17.15   Consents

        The Agent may at any time upon the application and at the cost of the
        Borrowers and without any consent of any of the Banks (only if and so
        far as its reasonable opinion the interests of the Banks shall not be
        materially prejudiced thereby) give any consent, approval or license
        required on the Agent under the terms of this Agreement, save where this
        Agreement expressly requires that such consent, approval or license
        should be given only with the approval of, or on the instructions of,
        the Banks, the Majority Banks or the Majority Creditors.





17.16   Evidence

        The Agent may accept a certificate signed by any director of the
        secretary of the Company or any Borrower as to any fact or matter on
        which the Agent may need or wish to be satisfied as sufficient evidence
        thereof and a like certificate that any assets in the opinion of the
        person so certifying have a particular value or produce a particular
        income or are suitable for a particular purpose as sufficient evidence
        that they have that value or produce that income or are so suitable and
        the Agent shall not be bound in any such case to call for further
        evidence or be responsible for any loss that may be occasioned by its
        failing to do so.

17.17   Distribution of Proceeds of Enforcement

17.17.1 In this Clause 17.17 the following expressions shall have the following
        meanings:

        "Bank Outstandings" means, in respect of a Bank (which expression for
        the purposes of this Clause 17.17 shall include the Working Capital
        Bank), the aggregate amount owed to such Bank by way of principal,
        interest, commission and fees in respect of the Facilities, including
        all amounts actually or contingently owed to the Working Capital Bank at
        such time under, or in respect of, the uncommitted Engagements Facility;
        and

        "Total Outstandings" means the aggregate of the Bank Outstandings of
        each Bank.

17.17.2 Subject to the terms of the Intercreditor Agreement on the enforcement
        of all or any of the Security Documents, any amount of enforcement
        proceeds paid to the Agent pursuant to the Intercreditor Agreement shall
        be applied as follows. The Agent shall be entitled to deduct from the
        proceeds of such enforcements its costs, charges and expenses incurred
        in connection with such enforcement together an amount equal to all sums
        due to the Agent hereunder before distributing to each Bank an amount
        equal to the remaining proceeds multiplied by:

                         Bank Outstanding of such Bank
                               Total Outstandings

        where Bank Outstandings, the Working Capital Bank's Outstandings and the
        Total Outstandings are all calculated as at the date of enforcement.

17.17.3 The Agent shall notify each Bank of any proposed distribution and the
        proposed date of distribution and each Bank shall provide to the Agent a
        calculation of what is due to it in respect of the sums referred to in
        Clause 17.17.1. The Agent shall send copies of all such calculations to
        all other Banks and, in the absence of manifest error, the Agent shall
        make the distributions on the basis of such calculations.

17.17.4 If any continent liability incurred in the calculation of Bank's
        Outstandings finally matures or is settled for less than the contingent
        amount provided for in the relevant calculations then the relevant Bank
        shall notify the Agent of that fact and such adjustment shall be made by
        payment by such Bank to the Agent for distribution amongst the Banks as
        may be necessary to put the Banks into the position they





        would have been in (but taking no account of the time cost of money) had
        the original distribution been made on the basis of the actual as
        opposed to the contingent liability.

17.17.5 The Agent may, at its discretion, accumulate proceeds of realisations on
        an interest bearing account in its own name until there is a minimum of
        (pound)500,000 to distribute under Clause 17.17.2.

17.18   Net Limits

        For the avoidance of doubt, any credit balances taken into account by a
        Bank when operating a net limit in respect of any overdraft under the
        Overdraft Facility shall not be subject to Clause 16.2 and shall, on the
        enforcement of the Security Documents, be applied first in reduction of
        the relevant overdraft provided under the Overdraft Facility to the
        extent taken into account in operating the net limit.

                                             (pound)

        relating thereto, which are imposed or charged on or in connection with
        any of the Financing Documents shall be paid by the Company PROVIDED
        THAT the Agent shall be entitled but not obliged to pay any such duties
        or Taxes (whether or not they are its primary responsibility), whereupon
        the Company shall on demand indemnify the Agent against those duties or
        Taxes and against any costs and expenses so incurred by the Agent in
        discharging them.

18.8    VAT

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

        Agent, the Bank or the Working Capital Bank to a Borrower pursuant to or

        document contemplated herein may be increased or added to by reference

        Where in the Financing Documents a Borrower has an obligation to
        indemnify or reimburse any of the Agent, the Banks and the Working
        Capital Bank in respect of any loss or payment, the calculation of the
        amount payable by way of indemnity or reimbursement shall take account
        of the actual Tax treatment in the hands of such person (as determined
        by the relevant person's auditors) of the amount payable by way of
        indemnity or reimbursement together with the loss or payment in respect
        of which the amount is payable.

19.     SEVERABILITY, WAIVERS, REMEDIES CUMULATIVE

19.1    Severance

        invalid or unenforceable in any respect under the law of any
        jurisdiction neither the legality, validity or enforceability of the
        remaining provisions hereof nor the legality, validity or enforceability
        of such provision under the law of any other jurisdiction shall in any
        way be affected or impaired thereby.

        No failure to exercise, nor any delay in exercising, on the part of any
        of the Agent, the Banks or the Working Capital Bank, any right or remedy

        partial exercise of any right or remedy prevent any further or other
        exercise thereof or the exercise of any other right or remedy. The

        Bank and other Banks that it shall be under the same obligations towards

        as a Bank, the Agent, the Working Capital Bank and the other 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.

21.3.3  If any Bank (the "Existing Bank") wishes to transfer all or any part of

        (i)     to the extent that in the Transfer Certificate the Existing Bank

                Borrowers and the Existing Bank shall each be released from
                further obligations to each other under this Agreement and their
                respective rights against each other shall be cancelled (such
                rights and obligations being referred to in this Clause 21.3.4
                as "Discharged Rights and Obligations");

        (ii)    the Borrowers and the Bank Transferee shall each assume
                obligations towards each other and/or acquire rights against
                each other which differ from the Discharged Rights and
                Obligations only insofar as the Borrower and the Bank Transferee
                have assumed and/or acquired the same in place of the Borrower
                and the Existing Bank;

        (iii)   the Agent, the Borrowers, the Working Capital Bank, the Bank
                Transferee and the other Banks shall acquire the same rights and
                assume the same obligations among themselves as they would have
                acquired and assumed had the Bank Transferee been a party
                hereunder as a Bank with the rights and/or the obligations
                acquired or assumed by it as a result of the transfer;

        (iv)    a proportion of the Existing Bank's rights under the Security
                Documents equal to the proportion of the Existing Bank's rights
                under this Agreement being transferred, shall automatically be
                transferred to the Bank Transferee; and

        (v)     a proportion of the Existing Bank's rights and obligations under
                the Intercreditor Agreement equal to the proportion of the
                Existing Bank's rights under this Agreement being transferred
                shall automatically be transferred to the Bank Transferee in
                accordance with the terms of the Intercreditor Agreement.

21.3.5  The Agent will promptly complete Transfer Certificates on request by an
        Existing Bank and upon payment by such Existing Bank of a fee of
        (pound)750 to the Agent. The Working Capital Bank, the Borrowers and
        each of the Banks hereby irrevocably authorize the Agent to execute any
        duly completed Transfer Certificate on its behalf provided that such
        authorisation does not extend to the execution of a Transfer Certificate
        on behalf of either the Existing Bank or the Bank Transferee named
        therein.

21.3.6  The Agent shall promptly notify the Company of the receipt and execution
        on its behalf by the Agent of any Transfer Certificate.

21.3.7  A Borrower shall be under no obligation to pay any greater amount under
        this Agreement following an assignment or transfer by a Bank of any of
        its rights or obligations pursuant to the foregoing provisions of this
        Clause 21 where, in the circumstances existing at the time of such
        assignment or transfer, such greater amount would not have been payable
        but for the assignment or transfer.





21.4    Disclosure of Information

        The Agent and the Banks may not disclose any information furnished or
        made available to them hereunder by the Borrowers unless such
        information is available in the public domain PROVIDED THAT such
        information may be disclosed to each other, their professional advisers
        and to any actual or potential assignee, transferee or sub-participant
        subject to the condition that each of the same undertakes to the Company
        to keep confidential any such information and not disclose it save in
        accordance with the provisions of this Clause 21.4.

22.     COUNTERPARTS

        This Agreement may be executed in any number of counterparts and all
        such counterparts when executed and taken together shall constitute one
        and the same Agreement.

23.     LAW

        This Agreement shall be governed by, and construed in all respects in
        accordance with, English law.

24.     CURRENCY INDEMNITY

        Any payment or payments made to or for the account of or received by the
        Agent, the Working Capital Bank or any Bank in respect of any monies or
        liabilities due, arising or incurred by any Borrower to the Agent, the
        Working Capital Bank or any Bank in a currency (the "Currency of
        Payment") other than the currency in which the payment should have been
        made pursuant to this Agreement (the "Currency of Obligation") in
        whatever circumstances (including, without limitation, as a result of a
        judgment against such Borrower) and for whatever reason shall constitute
        a discharge to such Borrower to the extent of the Currency of Obligation
        amount which the Agent, the Working Capital Bank or Bank, as the case
        may be, is able on the date or dates of receipt of such payment or
        payments (or if not a Business Day on the next succeeding Business Day)
        to purchase with the Currency of Payment amount in the London foreign
        exchange market. If the amount of the Currency of Obligation which the
        Agent, the Working Capital Bank or that Bank is so able to purchase
        falls short of the amount originally due to the Agent, the Working
        Capital Banks or that Bank, as the case may be, under this Agreement,
        then such Borrower shall indemnify and hold the Agent, the Working
        Capital Banks or that Bank, as the case may be, harmless against any
        loss or damage arising as a result thereof by paying to the Agent, the
        Working Capital Bank or that Bank, as the case may be, that amount in
        the Currency of Obligation certified by the Agent, the Working Capital
        Bank or that Bank, as the case may be, as necessary so to indemnify it.
        It is hereby declared that this indemnity shall constitute a separate
        and independent obligation from the other obligations contained in this
        Agreement, shall give rise to a 





        separate and independent cause of action, shall apply irrespective of
        any indulgence granted from time to time and shall continue in full
        force and effect notwithstanding any judgment or order for a liquidated
        sum or sums in respect of amounts due under this Agreement or under any
        such judgment or order. The certificate of the Agent, the Working
        Capital Bank or the relevant Bank, as the case may be, as to the amount
        of any such loss or damage as aforesaid shall, in the absence of
        manifest error, be conclusive and binding on each Borrower.

IN WITNESS whereof the parties hereto have caused this Agreement to be duly
executed on the date set out above.

                                   SCHEDULE 3

                      MANDATORY LIQUID ASSET COSTS FORMULA

(1)     The additional rate relative to an Advance shall, subject as hereinafter
        provided, be calculated in accordance with the following formula:


                         BY + L(Y-X) + S(Y-Z)% per annum
                         --------------------
                           100 - (B+S)

        Where on the day of the application of the formula:

        B =     The percentage of the Agent's eligible liabilities which the
                Bank of England then requires the Agent to Hold on a
                non-interest-bearing deposit account in accordance with its the
                Company ratio requirements.

        Y =     The rate at which Sterling deposits in an amount comparable with
                such Advance are offered by the Agent to leading banks in the
                London Inter-Bank Market at or about 11.00 a.m. on such day for
                the relevant period.

        L =     The percentage of eligible liabilities which (as a result of the
                requirements of the Bank of England) the Agent maintains as
                secured money with members of the London Discount Market
                Association or in certain marketable or callable securities
                approved by the Bank of England, which percentage shall (in the
                absence of evidence that any other figure is appropriate) be
                conclusively presumed to be 5 per cent.

        X =     The rate at which secured Sterling deposits in an amount
                comparable to such Advance may be placed by the Agent with
                members of the London Discount Market Association at or about
                11.00 a.m. on such day for the relevant period or, if greater,
                the rate at which Sterling bills of exchange (of an amount
                comparable to such Advance and of a tenor equal to the relevant
                period) eligible for rediscounting at the Bank of England can be
                discounted in the London Discount Market at or about 11.00 a.m.
                on that day.

        S =     The percentage of the Agent's eligible liabilities which the
                Bank of England requires the Agent to place as a special
                deposit.

        Z =     The percentage interest rate per annum allowed by the Bank of
                England on special deposits.

(2)     For the purposes of this Schedule 3:

        (i)     "eligible liabilities" and "special deposits" shall bear the
                meanings ascribed to them from time to time by the Bank of
                England; and

        (ii)    "relevant period" in relation to each Interest Period means:





                (a)     if it is 3 monthly or less, that Interest Period; or

                (b)     if it is more than 3 months, 3 months.

(3)     In the application of the above formula, B, Y, L, X, S and Z will be
        included in this formula as figures and not as percentages, e.g., if B =
        0.5% and Y = 15%, BY will be calculated as 0.5 x 15 and not as 0.5% x
        15%.

(4)     The additional rate computed by the Agent in accordance with this
        Schedule 3 shall, if not so already, be rounded upward to 4 decimal
        places.

(5)     In the event of a change in circumstances (including the imposition of
        alternative or additional official requirements) which renders the above
        formula inapplicable, the Agent shall notify Newco of the manner in
        which the additional rate shall thereafter be determined which shall
        reflect the additional costs following such change incurred by the Banks
        at such time and from time to time.





                                   SCHEDULE 4

governmental authority, as amended from time to time.

          1.2.2. Governing Law. This Guaranty shall be governed by, and
construed in accordance with, the laws of the State of New York (other than
choice of law rules that would require the application of the laws of any other

provisions hereof or the validity, legality or enforceability of such provision
in any other jurisdiction.

                                   ARTICLE 2.

                                    GUARANTY

          Section 2.1. Guaranty. The Guarantors unconditionally jointly and
severally guaranty and promise to pay to the order of the Security Trustee, for
the benefit of the Beneficiaries, on demand, in lawful money of the United
States of America, any and all Obligations of the Borrowers from time to time
owed to the Beneficiaries. The term "Obligations" is used herein in its most
comprehensive sense and includes any and all present and future obligations and
liabilities of the Borrowers of every type and description under any of the
Financing Documents to the Beneficiaries, or any of them, or any of their
successors or assigns, or any Person entitled to indemnification under the



                                    Guaranty

                                       4


Financing Documents, whether for principal, interest, letter of credit or other
reimbursement obligations, cash collateral cover, fees, expenses, indemnities or
other amounts (including attorney's fees and expenses), including without
limitation all Bank Liabilities (as defined in the Inter-Creditor Agreement) and
all Note Holder Liabilities (as defined in the Inter-Creditor Agreement),

in each case whether due or not due, direct or indirect, joint and/or several,
absolute or contingent, voluntary or involuntary, liquidated or unliquidated,
determined or undetermined, now or hereafter existing, renewed or restructured,
whether or not from time to time decreased or extinguished and later increased,
created or incurred, whether or not arising after the commencement of a
proceeding under the Bankruptcy Code (including post-petition interest) and
whether or not allowed or allowable as a claim in any such proceeding, and
whether or not recovery of any such obligation or liability may be barred by a
statute of limitations or such obligation or liability may otherwise be
unenforceable. All Obligations shall be conclusively presumed to have been
created in reliance on this Guaranty. All payments hereunder shall be made on
the same basis as payments by the Borrowers under Section 12.4 of the Credit
Agreement.

          Section 2.2. Continuing and Irrevocable Guaranty. This is a continuing
guaranty of the Obligations and may not be revoked and shall not otherwise
terminate unless and until the Obligations have been indefeasibly paid and
performed in full. If notwithstanding the foregoing any Guarantor shall have any
right under Applicable Law to terminate this Guaranty prior to indefeasible
payment in full of the Obligations, no such termination shall be effective until
noon the next Business Day after the Security Trustee shall receive written
notice thereof, signed by such Guarantor. Any such termination shall not affect
this Guaranty in relation to (a) any Obligation that was incurred or arose prior
to the effective time of such notice, (b) any Obligation incurred or arising
after such effective time where such Obligation is incurred or arises either
pursuant to commitments existing at such effective time or incurred for the
purpose of protecting or enforcing rights against any Borrower, any Guarantor or
other Guarantor of or other Person directly or indirectly liable on the
Obligations or any portion thereof (an "Other Guarantor") or any security
("Collateral") given for the Obligations or any other guaranties of the
Obligations or any portion thereof (an "Other Guaranty"), (c) any renewals,
extensions, readvances, modifications or rearrangements of any of the foregoing
or (d) the liability of any other Guarantor hereunder. Without limiting the
generality of the foregoing, if any part of the Obligations arises under
revolving credit facilities, then even if the Borrowers are no longer entitled
to further credit (as a result of the purported termination hereof or
otherwise), no termination of this Guaranty shall in any event be effective to
reduce the obligations of any Guarantor hereunder with respect to any extensions
of credit that may thereafter be made to the Borrowers by the Beneficiaries to
the extent that the outstanding amount of such credit (including letter of
credit and other contingent exposure), together with all other Obligations then
outstanding, does not exceed the aggregate amount of all Obligations outstanding
as of the time any termination of this Guarantor becomes effective.

                                       5


          Section 2.3. Nature of Guaranty. The liability of each Guarantor
hereunder is independent of and not in consideration of or contingent upon the
liability of any Borrower or any other Obligor and a separate action or actions
may be brought and prosecuted against any Guarantor, whether or not any action
is brought or prosecuted against any Borrower or any other Obligor or whether
any Borrower or any other Obligor is joined in any such action or actions. This
Guaranty shall be construed as a continuing, absolute and unconditional guaranty
of payment (and not merely of collection) without regard to:

          2.3.1. the legality, validity or enforceability of any of the
Financing Document, any of the Obligations, any Lien or Collateral or any Other
Guaranty;

          2.3.2. any defense (other than payment), set-off or counterclaim that
may at any time be available to any Borrower or any other Obligor against, and
any right of set-off at any time held by, any Beneficiary; or

          2.3.3. any other circumstance whatsoever (with or without notice to or
knowledge of any Guarantor or any other Obligor), whether or not similar to any
of the foregoing, that constitutes, or might be construed to constitute, an
equitable or legal discharge of any Borrower or any other Obligor, in bankruptcy
or in any other instance.

          Section 2.4. Authorization. Each Guarantor authorizes each
Beneficiary, without notice to or further assent by such Guarantor, and without
affecting any Guarantor's liability hereunder (regardless of whether any
subrogation or similar right that such Guarantor may have or any other right or
remedy of such Guarantor is extinguished or impaired), from time to time to:

          2.4.1. permit any Borrower to increase or create Obligations, or
terminate, release, compromise, subordinate, extend, accelerate or otherwise
change the amount or time, manner or place of payment of, or rescind any demand
for payment or acceleration of, the Obligations or any part thereof (including
increasing or decreasing the rate of interest thereon), or otherwise amend the
terms and conditions of any of the Financing Documents or any provision thereof;

          2.4.2. take and hold Collateral from any Borrower or any other Person,
perfect or refrain from perfecting a Lien on such Collateral, and exchange,
enforce, subordinate, release (whether intentionally or unintentionally), or
take or fail to take any other action in respect of, any such Collateral or Lien
or any part thereof;

          2.4.3. exercise in such manner and order as it elects in its sole
discretion, fail to exercise, waive, suspend, terminate or suffer expiration of,
any of the remedies or rights of such Beneficiary against any Borrower or any
other Obligor in respect of any Obligations or any Collateral;

          2.4.4. release, add or settle with any Obligor in respect of this
Guaranty, any Other Guaranty or the Obligations;



                                    Guaranty

                                       6


          2.4.5. accept partial payments on the Obligations and apply any and
all payments or recoveries from any Obligor or Collateral to such of the
Obligations as each Beneficiary may elect in its sole discretion, whether or not
such Obligations are secured or guaranteed;

          2.4.6. refund at any time, at such Beneficiary's sole discretion, any
payments or recoveries received by such Beneficiary in respect of any
Obligations or Collateral; and

          2.4.7. otherwise deal with any Borrower, any other Obligor and any
Collateral as such Beneficiary may elect in its sole discretion.

          Section 2.5. Certain Waivers. Each Guarantor waives:

          2.5.1. the right to require the Beneficiaries to proceed against any
Borrower or any other Obligor, to proceed against or exhaust any Collateral or
to pursue any other remedy in any Beneficiary's power whatsoever and the right
to have the property of the Borrowers or any other Obligor first applied to
the discharge of the Obligations;

          2.5.2. all rights and benefits under any applicable law purporting to
reduce a guarantor's obligations in proportion to the obligation of the
principal or providing that the obligation of a surety or guarantor must neither
be larger nor in other respects more burdensome than that of the principal;

          2.5.3. the benefit of any statute of limitations affecting the
Obligations or any Guarantor's liability hereunder and of Section 359.5 of the
California Code of Civil Procedure;

          2.5.4. any requirement of marshaling or any other principle of
election of remedies and all rights and defenses arising out of an election of
remedies by any Beneficiary, even though that election of remedies, such as
nonjudicial foreclosure with respect to the security for a guaranteed
obligation, has destroyed any Guarantor's rights of subrogation and
reimbursement against any Borrower by the operation of Section 580d of the
California Code of Civil Procedure or otherwise;

          2.5.5. any right to assert against any Beneficiary any defense (legal
or equitable), set-off, counterclaim and other right that any Guarantor may now
or any time hereafter have against any Borrower or any other Obligor;

          2.5.6. presentment, demand for payment or performance (including
diligence in making demands hereunder), notice of dishonor or nonperformance,
protest, acceptance and notice of acceptance of this Guaranty, and all other
notices of any kind, including (i) notice of the existence, creation or
incurrence of new or additional Obligations, (ii) notice of any action taken or
omitted by the Beneficiaries in reliance hereon, (iii) notice of any default by
the Borrowers or any other Obligor, (iv) notice that

                                       7


any portion of the Obligations is due, (v) notice of any action against any
Borrower or any other Obligor, or any enforcement of other action with respect
to any Collateral, or the assertion of any right of any Beneficiary hereunder;

          2.5.7 all defenses that at any time may be available to any Guarantor
by virtue of any valuation, stay, moratorium or other law now or hereafter in
effect;

          2.5.8. any rights, defenses and other benefits any Guarantor may have
by reason of any failure of any Beneficiary to hold a commercially reasonable
public or private foreclosure sale or otherwise to comply with applicable law in
connection with a disposition of the Collateral; and

          2.5.9. without limiting the generality of the foregoing or any other
provision hereof, all rights and benefits under California Civil Code Sections
2810, 2819, 2839, 2845, 2848, 2849, 2850, 2899, and 3433 or any similar
provisions of applicable law.

          Section 2.6. Subrogation; Certain Agreements.

          2.6.1 EACH GUARANTOR WAIVES ANY AND ALL RIGHTS OF SUBROGATION,
INDEMNITY, CONTRIBUTION OR REIMBURSEMENT, AND ANY AND ALL BENEFITS OF AND RIGHTS
TO ENFORCE ANY POWER, RIGHT OR REMEDY THAT ANY BENEFICIARY MAY NOW OR HEREAFTER
HAVE IN RESPECT OF THE OBLIGATIONS AGAINST ANY BORROWER OR ANY OTHER OBLIGOR,
ANY AND ALL BENEFITS OF AND RIGHTS TO PARTICIPATE IN ANY COLLATERAL, WHETHER
REAL OR PERSONAL PROPERTY, NOW OR HEREAFTER HELD BY ANY BENEFICIARY, AND ANY AND
ALL OTHER RIGHTS AND CLAIMS (AS DEFINED IN THE BANKRUPTCY CODE) ANY GUARANTOR
MAY HAVE AGAINST ANY BORROWER OR ANY OTHER OBLIGOR, UNDER APPLICABLE LAW OR
OTHERWISE, AT LAW OR IN EQUITY, BY REASON OF ANY PAYMENT HEREUNDER, UNLESS AND
UNTIL THE OBLIGATIONS SHALL HAVE BEEN PAID IN FULL. Without limitation, the
Guarantors shall exercise no voting rights, shall file no claim, and shall not
participate or appear in any bankruptcy or insolvency case involving any
Borrower with respect to the Obligations unless and until all the Obligations
shall have been paid in full. If, notwithstanding the foregoing, any amount
shall be paid to any Guarantor on account of any such rights at any time, such
amount shall be held in trust for the benefit of the Beneficiaries and shall
forthwith be paid to the Security Trustee to be held as Collateral or credited
and applied in accordance with the terms of the Inter-Creditor Agreement and the
other Financing Documents upon the Obligations, whether matured, unmatured,
absolute or contingent, in the discretion of the Security Trustee.

          2.6.2. Each Guarantor assumes the responsibility for being and keeping
itself informed of the financial condition of each Borrower and each other
Obligor and of all other circumstances bearing upon the risk of nonpayment of
the Obligations that 



                                    Guaranty

                                        8


diligent inquiry would reveal, and agrees that the Beneficiaries shall have no
duty to advise any Guarantor of information regarding such condition or any such
circumstances.

          Section 2.7. Bankruptcy No Discharge.

          2.7.1. Without limiting Section 2.3., this Guaranty shall not be
discharged or otherwise affected by any bankruptcy, reorganization or similar
proceeding commenced by or against any Borrower or any other Obligor, including
(i) any discharge of, or bar or stay against collecting, all or any part of the
Obligations in or as a result of any such proceeding, whether or not assented to
by any Beneficiary, (ii) any disallowance of all or any portion of any
Beneficiary's claim for repayment of the Obligations, (iii) any use of cash or
other collateral in any such proceeding, (iv) any agreement or stipulation as to
adequate protection in any such proceeding, (v) any failure by any Beneficiary
to file or enforce a claim against any Borrower or any other Obligor or its
estate in any bankruptcy or reorganization case, (vi) any amendment,
modification, stay or cure of any Beneficiary's rights that may occur in any
such proceeding, (vii) any election by any Beneficiary under Section 1111(b)(2)
of the Bankruptcy Code, or (viii) any borrowing or grant of a Lien under Section
364 of the Bankruptcy Code. Each Guarantor understands and acknowledges that by
virtue of this Guaranty, it has specifically assumed any and all risks of any
such proceeding with respect to each Borrower and each other Obligor.

          2.7.2. Notwithstanding anything to the contrary herein contained, this
Guaranty (and any Lien on the Collateral securing this Guaranty or the
Obligations) shall continue to be effective or be reinstated, as the case may
be, if at any time any payment, or any part thereof, of any or all of the
Obligations is rescinded, invalidated, declared to be fraudulent or preferential
or otherwise required to be restored or returned by any Beneficiary in
connection with any bankruptcy, reorganization or similar proceeding involving
any Borrower, any other Obligor or otherwise, if the proceeds of any Collateral
are required to be returned by such Beneficiary under any such circumstances, or
if any Beneficiary elects to return any such payment or proceeds or any part
thereof in its sole discretion, all as though such payment had not been made or
such proceeds not been received. Without limiting the generality of the
foregoing, if prior to any such rescission, invalidation, declaration,
restoration or return, this Guaranty shall have been canceled or surrendered (or
if any Lien or Collateral shall have been released or terminated in connection
with such cancellation or surrender), this Guaranty (and such Lien and
Collateral) shall be reinstated in full force and effect, and such prior
cancellation or surrender shall not diminish, discharge or otherwise affect the
obligations of the Guarantors in respect of the amount of the affected payment
or application of proceeds (or such Lien or Collateral).

          Section 2.8. Subordination.

          2.8.1. Each Guarantor hereby absolutely subordinates, both in right of
payment and in time of payment, any and all present or future obligations and
liabilities



                                    Guaranty

                                       9


of any Borrower and each other Obligor to such Guarantor ("Subordinated Debt"),
to the prior payment in full in cash of the Obligations, whether or not such
Subordinated Debt constitutes or arises out of any subrogation, reimbursement,
contribution, indemnity or similar right attributable to this Guaranty. If,
whether or not at any Beneficiary's request, any Guarantor shall receive, prior
to payment in full in cash of all Obligations, payment of any sum from any
Borrower or any other Obligor upon any Subordinated Debt, any such sum shall be
received by such Guarantor as trustee for the Beneficiaries and shall forthwith
be paid over to the Security Trustee on account of the Obligations, without
reducing or affecting in any manner the liability of any Guarantor under this
Guaranty.

          2.8.2. Each Guarantor shall file in any bankruptcy or reorganization
or similar proceeding in which the filing of claims is required by applicable
law, all claims that such Guarantor may have against any Borrower or other
Obligor (or its nominee) relating to any Subordinated Debt. If the Guarantor
does not file any such claim, the Security Trustee (or its nominee) as
attorney-in-fact for the Guarantor is hereby authorized to do so in the name of
such Guarantor. Each Guarantor agrees that, in connection with any such
proceeding, it shall not contest or oppose the treatment of claims of the
Beneficiaries in any plan of reorganization or otherwise and it shall vote any
claims that exist by virtue of this Guaranty or the Subordinated Debt in
connection with any plans of reorganization or otherwise, as may be requested by
the Security Trustee.

          2.8.3. Each Guarantor hereby grants the Security Trustee a power of
attorney for the purposes set forth in this Section 2.8. Such power of attorney
is coupled with an interest and cannot be revoked.

          Section 2.9. Maximum Liability of Guarantors. The obligations of each
Guarantor hereunder shall be limited to an aggregate amount equal to the largest
amount that would not render its obligations hereunder subject to avoidance
under Section 548 of the Bankruptcy Code or any applicable provisions of
comparable state law.

          Section 2.10. Right of Contribution. In order to provide for just and
equitable contribution among the Guarantors and any Other Guarantors (for
purposes of this Section only, each Guarantor and each Other Guarantor is
referred to as a "Guarantor"), in connection with the execution of this
Guaranty, the Guarantors have agreed among themselves that if any Guarantor
satisfies some or all of the Obligations (a "Funding Guarantor"), the Funding
Guarantor shall be entitled to contribution from the other Guarantors that have
positive Maximum Net Worth (as defined below) for all payments made by the
Funding Guarantor in satisfying the Obligations, so that each Guarantor that
remains obligated under this Guaranty or any Other Guaranty at the time
that a Funding Guarantor makes such payment (a "Remaining Guarantor") and has a
positive Maximum Net Worth shall bear a portion of such payment equal to the
percentage that such Remaining Guarantor's Maximum Net Worth bears to the
aggregate Maximum Net Worth of all Remaining Guarantors that have positive
Maximum Net Worth.



                                    Guaranty

                                       10


          As used herein, "Net Worth" means, with respect to any Guarantor, the
amount, as of the respective date of calculation, by which the sum of a Person's
assets (including subrogation, indemnity, contribution, reimbursement and
similar rights that the Guarantor may have), determined on the basis of a "fair
valuation" or their "fair saleable value" (whichever is the applicable test
under Section 548 and other relevant provisions of the Bankruptcy Code and the
relevant state fraudulent conveyance or transfer laws), is greater than the
amount that will be required to pay all of such Person's debts, in each case
matured or unmatured, contingent or otherwise, as of the date of calculation,
but excluding liabilities arising under this Guaranty or any Other Guaranty and
excluding, to the maximum extent permitted by applicable law with the objective
of avoiding rendering such Person insolvent, liabilities subordinated to the
Obligations arising out of loans or advances made to such Person by any other
Person. "Maximum Net Worth" means, with respect to any Guarantor, the greatest
of the Net Worth of such Guarantor calculated as of the following dates: (A) the
date on which such Person becomes a Guarantor, (B) the date on which such
Guarantor expressly reaffirms this Guaranty or the Other Guaranty to which it
is a party, (C) the date on which demand for payment is made on such Guarantor
hereunder or under such Other Guaranty, (D) the date on which payment is made by
such Guarantor hereunder or thereunder or (E) the date on which any judgment,
order or decree is entered requiring such Guarantor to make payment hereunder or
in respect hereof or under or in respect of such Other Guaranty. The meaning of
the terms "fair valuation" and "fair saleable value" and the calculation of
assets and liabilities shall be determined and made in accordance with the
relevant provisions of the Bankruptcy Code and applicable state fraudulent
conveyance or transfer laws.

                                   ARTICLE 3.

                         REPRESENTATIONS AND WARRANTIES

          Each Guarantor represents and warrants that all representations and
warranties made with respect to it, its assets and its obligations in Section
13.2 of the Credit Agreement are true and correct and makes the following
additional representations and warranties, all of which shall survive until
termination of this Guaranty pursuant to Section 2.2.

          Section 3.1. Financial Benefit. Each Guarantor hereby acknowledges and
warrants it has derived or expects to derive a financial advantage from each
loan or other extension of credit and each renewal, extension, release of
Collateral, or other relinquishment of legal rights, made or granted or to be
made or granted by the Beneficiaries in connection with the Obligations. After
giving effect to this Guaranty and the other Financing Documents to which any
Guarantor is a party, and the transactions contemplated hereby and thereby, each
Guarantor is not Insolvent or left with assets or capital that is unreasonably
small in relation to its business or the Obligations. "Insolvent" means, with
respect to any Guarantor, that (a) determined on the basis of a "fair valuation"
or their "fair saleable value" (whichever is the applicable test under



                                    Guaranty

                                       11


Section 548 and other relevant provisions of the Bankruptcy Code and the
relevant state fraudulent conveyance or transfer laws) the sum of such
Guarantor's assets is less than its debts, or (b) such Guarantor is generally
not paying its debts as they become due.

          Section 3.2. Review of Documents; Understanding With Respect to
Waivers. Each Guarantor hereby acknowledges that it has copies of and is fully
familiar with the Credit Agreement, the U.S. Loan Notes and each other Financing
Document. Each Guarantor warrants and agrees that each waiver set forth in this
Guaranty is made with such Guarantor's full knowledge of its significance and
consequences and after opportunity to consult with counsel of its own choosing
and that, under the circumstances, each such waiver is reasonable and should not
be found contrary to public policy or law.

                                   ARTICLE 4.

                                  MISCELLANEOUS

          Section 4.1. Expenses. Each Guarantor shall pay to the Security
Trustee any and all costs and expenses, (including attorneys' fees and
expenses), that any Beneficiary may incur in connection with (a) the collection
of all sums guaranteed hereunder or (b) the exercise or enforcement of any of
the rights, powers or remedies of the Beneficiaries under this Guaranty or
applicable law. All such amounts and all other amounts payable hereunder shall
be payable on demand, together with interest at the Default Rate, from and
including the due date to and excluding the date of payment.

          Section 4.2. Amendments and Other Modifications. No amendment of any
provision of this Guaranty (including a waiver thereof or consent relating
thereto) shall be effective unless the same shall be in writing and signed by
the Security Trustee. Any waiver or consent relating to any provision of this
Guaranty shall be effective only in the specific instance and for the specific
purpose for which given. No notice to or demand on any Guarantor in any case
shall entitle such Guarantor to any other or further notice or demand in similar
or other circumstances.

          Section 4.3. Cumulative Remedies; Failure or Delay. The rights and
remedies provided for under this Guaranty are cumulative and are not exclusive
of any rights and remedies that may be available to the Beneficiaries under
applicable law or otherwise. No failure or delay on the part of any Beneficiary
in the exercise of any power, right or remedy under this Guaranty shall impair
such power, right or remedy or shall operate as a waiver thereof, nor shall any
single or partial exercise of any such power, right or remedy preclude other or
further exercise of such or any other power, right or remedy.

          Section 4.4. Notices, Etc. All notices and other communications under
this Guaranty shall be in writing and shall be personally delivered or sent by
prepaid courier, by overnight, registered or certified mail (postage prepaid),
or by prepaid telex, 



                                    Guaranty

                                       12


telecopy or telegram, and shall be deemed given when received by the intended
recipient thereof. Unless otherwise specified in a notice given in accordance
with the foregoing provisions of this Section, all notices and other
communications shall be given to the parties hereto at their respective
addresses (or to their respective telex or telecopier numbers) indicated on
Schedule 4.4.

          Section 4.5. Successors and Assigns. This Guaranty and each amendment
hereof shall be binding upon and, subject to the next sentence, inure to the
benefit of each Guarantor, the Beneficiaries and their respective successors and
assigns. The Guarantor shall not assign any of its rights or obligations
hereunder without the prior written consent of the Security Trustee. The benefit
of this Guaranty shall automatically pass with any assignment of the Obligations
(or any portion thereof), to the extent of such assignment.

          Section 4.6. Choice of Forum.

          4.6.1. Each of the Guarantors irrevocably agrees for the benefit of
each of the Beneficiaries that the courts of England shall have jurisdiction to
hear and determine any suit, action or proceeding, and to settle any disputes,
which may arise out of or in connection with this Guaranty (and the other
Financing Documents) and, for such purposes, irrevocably submits to the
jurisdiction of such courts. Each of the Guarantors irrevocably agrees that the
courts of the State of New York and the courts of the United States of America
in New York shall have jurisdiction to hear and determine any suit, action or
proceeding, and to settle any disputes, which may arise out of or in connection
with this Guaranty (and the other Financing Documents) and, for such purposes,
irrevocably submits to the jurisdiction of such courts. Each of the Guarantors
irrevocably waives any objection which it might now or hereafter have to the
courts referred to in this Section 4.6.1 being nominated as the forum to hear
and determine any suit, action or proceeding, and to settle any disputes, which
may arise out of or in connection with this Guaranty and the Financing Documents
and agrees not to claim that any such court is not a convenient or appropriate
forum.

          IN ANY ACTION AGAINST ANY GUARANTOR, SERVICE OF PROCESS MAY BE MADE
UPON SUCH GUARANTOR BY DELIVERY OR BY REGISTERED OR CERTIFIED MAIL, RETURN
RECEIPT REQUESTED, TO ITS ADDRESS INDICATED IN SCHEDULE 4.4., WHICH SERVICE
SHALL BE DEEMED SUFFICIENT FOR PERSONAL JURISDICTION AND SHALL BE DEEMED
EFFECTIVE UPON RECEIPT, IN THE CASE OF DELIVERY, AND 10 DAYS AFTER MAILING, IN

METHOD OF SERVICE PROVIDED FOR UNDER APPLICABLE LAWS IN EFFECT IN THE STATE OF

gaining knowledge thereof, irrevocably shall appoint a substitute process agent
acceptable to the Security Trustee in the County of New York and advise the
Security Trustee thereof.

          4.6.2. The submission to the jurisdiction of the courts referred to in
Section 4.6.1 shall not (and shall not be construed as to) limit the right of
the Beneficiaries or any of them to take proceedings against any of the
Guarantors in any other court of competent jurisdiction nor shall the taking of
proceedings in any one or more jurisdictions preclude the taking of proceedings
in any other jurisdiction (whether concurrently or not) if and to the extent
permitted by applicable law.

granted under applicable law and not by way of limitation of any such rights,
upon the occurrence and during the continuation of any Default, each
Beneficiary, each holder or transferee of any Obligations or any Person with any
interest therein is hereby irrevocably authorized by each Guarantor, at any time
or from time to time, without notice to such Guarantor or to any other Person,
any such notice being hereby expressly waived, to set off and to appropriate and
to apply any and all deposits (general or special, including certificates of
deposit, whether matured or unmatured, but not including trust accounts) and any
other indebtedness, in each case whether direct or indirect or contingent or
matured or unmatured at any time held or owing by such Beneficiary, such holder,
such transferee or such other Person, to or for the credit or the account of

currency of account and payment for each and every sum at any time due from the
Guarantors hereunder; provided that any amount of Obligations expressed to be
payable in a currency other than dollars shall be paid in that other currency.
If any sum due from any Guarantor under this Guaranty (or any sum due from any
Borrower under any Financing Document in respect of which any Guarantor is
obligated hereunder) or any order or judgment given or made in relation thereto
has to be converted from the currency (the "first currency") in which the same
is payable thereunder or under such order or judgment into another currency (the
"second currency") for the purpose of (i) making or filing a claim or proof
against such Guarantor, (ii) obtaining an order or judgment in any court or
other tribunal or (iii) enforcing any order or judgment given or made in
relation hereto, the Guarantors shall indemnify and hold harmless the
Beneficiaries from and against any loss suffered as a result of any discrepancy
between (a) the rate of exchange used for such purpose to convert the sum in
question from the first currency into the second currency and (b) the rate or
rates of exchange at which such person may in the ordinary course of business
purchase the first currency with the second currency upon receipt of a sum paid
to in satisfaction, in whole or in part, of any such order, judgment, claim or
proof.

          Section 4.9. Application of Payments and Collections. In the case of
any payments by or collection from any Guarantor hereunder, the proceeds of such
payment or collection shall be applied in the manner set forth in Clause 5 of
the Inter-Creditor Agreement.

          Section 4.10. Execution in Counterparts. This Guaranty may be executed
in any number of counterparts, each of which counterparts, when so executed and
delivered, shall be deemed to be an original and all of which counterparts,
taken together, shall constitute but one and the same Guaranty.

          Section 4.11. Complete Agreement. This Guaranty, together with the
exhibits and schedules hereto and other Financing Documents, is intended by the
parties as the final expression of their agreement regarding the subject matter
hereof and as a complete and exclusive statement of the terms and conditions of
such agreement.

Guarantor against any Beneficiary or the affiliates, directors, officers,
employees or agents of any Beneficiary for any special, indirect, consequential
or punitive damages in respect of any claim for breach of contract or under any
other theory of liability arising out of or related to the transactions
contemplated by this Guaranty, or any act, omission or event occurring in
connection therewith; and each Guarantor waives, releases and agrees not to sue
upon any claim for any such damages, whether or not accrued and whether or not
known or suspected to exist in its favor.

Pledgor of this Agreement and each other Financing Document to which such
Pledgor is a party, the consummation of the transactions contemplated hereby or
thereby, or the exercise by the Security Trustee of any of the voting and other
rights or remedies hereunder, do not and will not (a) violate any provision of
the charter or bylaws of such Pledgor, (b) conflict with, result in a breach of
or constitute (or, with the giving of notice or lapse of time or both,
constitute) a default under, or require the approval or consent of any Person
pursuant to, any contractual obligation of such Pledgor or violate any provision
of Applicable Law binding on such Pledgor, or (c) result in the creation or
imposition of any Lien of any nature whatsoever upon any of such Pledgor's
assets except for Liens created under this Agreement and the other Financing
Documents. Except for filings and recordings in connection with the perfection
of Liens created by the Financing Documents, all of which have been made and are
in full force and effect, no Governmental Approval is or will be required in
connection with the execution, delivery and performance by any Pledgor of this
Agreement or any other Financing Documents to which any Pledgor is a party, the
consummation of the transactions contemplated hereby or thereby, or the exercise
by the Security Trustee of any of the voting and other rights or remedies
hereunder, or to ensure the legality, validity or enforceability hereof or
thereof, except as may be required in connection with the disposition of
Collateral by laws affecting the offering and sale of securities generally.

          Section 3.2. Title to Collateral: Validity and Perfection of Security
Interest; Absence of Other Liens.

          3.2.1. Each Pledgor has good and marketable title to all Collateral.
The Security Interest constitutes a valid and, upon delivery of all Pledged

Obligations.

          3.2.2. The Collateral is free and clear of all Liens other than the
Security Interest and other Liens in favor of Security Trustee.

          Section 3.3. Regarding the Pledged Stock. Schedule 3.3. sets forth the
number of authorized and the number of issued shares of each class of capital
stock of each issuer of Pledged Stock. All outstanding capital stock of each

outstanding options, warrants, convertible securities or other rights,
contingent or absolute, to acquire any capital stock of any such issuer.

                            COVENANTS AND AGREEMENTS

          Section 4.1. Delivery of Pledged Collateral, Etc.

          4.1.1. On the date hereof, each Pledgor is delivering to the Security
Trustee all Collateral consisting of certificated securities, instruments or the
like the physical possession of which is necessary in order for the Security
Interest to be perfected or delivery of which was requested by the Security
Trustee to assure the priority of the Security Interest therein (such Collateral
being "Pledged Collateral"). Each Pledgor shall deliver to the Security Trustee
promptly after acquisition thereof all Pledged Collateral acquired after the
date hereof. All Pledged Collateral shall be in suitable form for transfer by
delivery, or be accompanied by duly executed instruments of transfer or
assignment in blank, all in form and substance satisfactory to the Security
Trustee. The Security Trustee shall have the right, at any time in its
discretion and without notice to any Pledgor, to transfer to or to register in
the name of the Security Trustee or its nominee any or all of the Collateral,
subject only to the revocable rights specified in Section 4.7.1. In addition,
the Security Trustee shall have the right at any time to exchange certificates
or instruments representing or evidencing Pledged Collateral for certificates or
instruments of smaller or larger denominations.

          4.1.2. Without limitation of Section 4.1.1., if any Pledgor receives
or becomes entitled to receive any securities issues by any issuer of Pledged
Stock, or any successor thereto, in any manner in substitution for or in
addition to the Pledged Stock, or if any Pledgor shall become entitled to
receive or shall receive any securities or other property in addition to, in
substitution of, as a conversion of, or in exchange for, any of the Pledged
Stock or any other Collateral, such Pledgor shall receive the same as the agent
for the Security Trustee, and shall hold the same in trust for and deliver the
same promptly to the Security Trustee in the exact form in which received,
together with appropriate instruments of transfer or assignments in blank, to be
held by the Security Trustee as Collateral hereunder.

          Section 4.2. Further Assurances. Each Pledgor shall, at its own
expense, perform on request of the Security Trustee, such acts as may be
necessary or advisable in the opinion of the Security Trustee, or that the
Security Trustee may request at any time, to assure the attachment, perfection
and first priority of the Security Interest, to exercise the rights and remedies
of the Secured Parties hereunder or to carry out the intent of this Agreement.

          Section 4.3. Power of Attorney. Each Pledgor hereby irrevocably
appoints the Security Trustee and its employees and agents as such Pledgor's
true and lawful attorneys-in-fact, with full power of substitution, to do (a)
all things required to be 



                                Pledge Agreement

                                       8


done by such Pledgor under this Agreement or the other Financing Documents, and
(b) to do all things that the Security Trustee may deem necessary or advisable
to assure the attachment, perfection and first priority of the Security Interest
or otherwise to exercise the rights and remedies of the Secured Parties
hereunder or carry out the intent of this Agreement, in each case irrespective
of whether a Default or Default Occurrence then exists (except as otherwise
provided herein) and at the Pledgor's expense. Without limitation, the Security
Trustee and its officers and agents shall be entitled to affix, by facsimile
signature or otherwise, the general or special endorsement of any Pledgor, in
such manner as the Security Trustee shall deem advisable, to any Collateral that
has been delivered to or obtained by the Security Trustee without appropriate
endorsement or assignment, which endorsement shall be effective for all
purposes.

          Section 4.4. Payments of Charges and Claims. Each Pledgor shall pay
(a) all Charges imposed upon any Collateral, and (b) all claims that have become
due and payable and, under Applicable Law, have or may become Liens upon any
Collateral, in each case before any penalty shall be incurred with respect
thereto; provided that, unless foreclosure, levy or similar proceedings shall
have commenced, such Pledgor need not pay or discharge any such Charges to
claims so long as the validity or amount thereof is being contested in good
faith and by appropriate proceedings and so long as adequate reserves therefore
have been established in accordance with generally accepted accounting
principles. If any Pledgor fails to pay or obtain the discharge of any Charge,
claim or Lien required to be paid or discharged under this Section and asserted
against any material portion of the Collateral, the Security Trustee may, at any
time and from time to time, in its sole discretion and without waiving or
releasing any obligation of such Pledgor under this Agreement or the other
Financing Documents or waiving any Default or Event of Default, make such
payment, obtain such discharge or take such other action with respect thereto as
the Security Trustee deems advisable; provided, however, that the Security
Trustee shall in any event first have given such Pledgor written notice of its
intent to do the same and such Pledgor shall not have, within 15 days of such
notice, paid such claim or obtained to the Security Trustee's satisfaction the
release of the claim or Lien to which such notice relates.

          Section 4.5. Duty of Care.

          4.5.1 The Secured Parties shall have no duty of care with respect to
the Collateral, except that each Secured Party shall have an obligation to
exercise reasonable care with respect to Collateral in its possession; provided
that (i) each Secured Party shall be deemed to have exercised reasonable care if
Collateral in its possession is accorded treatment substantially comparable to
that which such Secured Party accords its own property or treatment
substantially in accordance with actions requested by any Pledgor in writing,
although the Secured Party shall not be obligated to comply with any such
requests, and (ii) the Secured Parties shall have no obligation to take any
actions to preserve rights against other parties with respect to any Collateral.
Without limitation, the Secured Parties shall have no duty with respect to



                                Pledge Agreement

                                       9


calls, conversions, presentments, maturities, notices or other matters relating
to Collateral, or to maximize interest or other returns with respect thereto.

          4.5.2 Each Pledgor hereby agrees to indemnify and hold harmless each
Secured Party and its directors, officers, employees and agents against any and
all claims, actions, liabilities, costs and expenses of any kind or nature
whatsoever (including reasonable fees and disbursements of counsel) that may be
imposed on, incurred by, or asserted against any of them, in any way relating to
or arising out of this Agreement or any action taken or omitted by them
hereunder, except to the extent a court holds in a final and nonappealable
judgment that they directly resulted from the gross negligence or willful
misconduct of such Persons against and from all such obligations and
liabilities.

          4.5.3 The Security Trustee may at any time deliver or redeliver the
Collateral or any part thereof to any Pledgor and the receipt of any of the same
by such Pledgor shall be complete and full acquittance for the Collateral so
delivered, and the Security Trustee thereafter shall be discharged from any
liability or responsibility therefor.

          Section 4.6 Sale of Collateral; Further Encumbrances. No Pledgor shall
(a) except for dispositions with the prior written consent of the Security
Trustee ("Permitted Sales"), sell, lease or otherwise dispose of any Collateral,
or any interest therein, or (b) grant or suffer to exist any Lien in or on any
Collateral. Concurrently with any Permitted Sale, the Security Interest shall
automatically be released from the Collateral so disposed of; provided, however
that the Security Interest shall continue in the Proceeds thereof. If any
Collateral, or any interest therein, is disposed of in violation of these
provisions, the Security Interest shall continue in such Collateral or interest
notwithstanding such disposition, the Person to which the Collateral or interest
is being transferred shall be bound by this Agreement, and the Pledgor shall
deliver all Proceeds thereof to the Security Trustee to be held as Collateral
hereunder.

          Section 4.7 Voting and Other Consensual Rights; Distributions.

          4.7.1. So long as no Default shall exist:

               4.7.1.1. Each Pledgor shall be entitled to exercise any and all
voting and other consensual rights pertaining to any Collateral, for any purpose
not inconsistent with the terms of this Agreement and the other Financing
Documents; provided, however, that such Pledgor shall not exercise any such
right if it would result in a Default or a Default Occurrence or have a Material
Adverse Effect. Within 10 days of exercising any such right in a manner material
to the Secured Parties, the Pledgor shall give notice to the Security Trustee of
such exercise and the action taken or approved in connection therewith.

               4.7.1.2. Except as otherwise provided herein, each Pledgor shall
be entitled to receive and retain and use free of the Security Interest any and
all cash



                                Pledge Agreement

                                       10


and other property paid or otherwise distributed in respect to the Collateral;
provided, however, that any and all (A) dividends and other distributions paid
or payable other than in cash and (B) cash paid upon or in respect of any of the
Collateral upon or in respect of the liquidation or dissolution of any issuer
thereof or upon or in respect of any distribution of capital or redemption or
exchange of any Collateral shall be delivered to the Security Trustee, in the
exact form received, to be held as Collateral hereunder.

          4.7.2. So long as a Default shall exist, at the sole option of the
Security Trustee, any or all rights of the Pledgors to exercise voting and other
consensual rights and to receive cash and other property distributed in respect
of Collateral as permitted above by this Section, shall cease, at the option of
the Security Trustee, and the Security Trustee, if and when it notified the
Pledgors of the exercise of such option, shall have the sole right to exercise
any or all such voting and other consensual rights and receive and to hold as
Collateral any or all such cash and other property.

          4.7.3. All cash and other property required to be delivered to the
Security Trustee hereunder shall, if received by any Pledgor, be received in
trust for the benefit of the Secured Parties, be segregated from the other
property of the Pledgors, and promptly be delivered to the Security Trustee in
the same form as so received (with any appropriate endorsements of assignments).

          4.7.4. The Security Trustee shall execute and deliver (or cause to be
executed and delivered) to the Pledgors all proxies and other instruments as any
Pledgor may reasonably request for the purpose of enabling such Pledgor to
exercise the voting and other rights which it is entitled to exercise pursuant
to this Section.

          Section 4.8. Registration Rights.

          4.8.1. Each Pledgor agrees that, at any time following the occurrence
of an Acceleration, upon request of the Security Trustee and without expense to
the Secured Parties, it shall at its own expense:

               4.8.1.1. use its best efforts to obtain all necessary
Governmental Approvals for the sale by the Security Trustee of the Collateral or
any part thereof;

               4.8.1.2. prepare, cause to be filed and use its best efforts to
cause to become effective with respect to the Collateral, or any part thereof,
one or more registration statements under the Securities Act of 1933, as amended
(or any similar statute from time to time in effect, the "Securities Act"), on
Form S-1 (or such other form for which the respective issuer of the Collateral
then qualifies and which is available for the sale of the Collateral in
accordance with the intended method of disposition thereof) or one or more
qualifications for exemption from registration or similar documents under the
Securities Act relating to any public offering or sale by the Security Trustee
of such Collateral;



                                Pledge Agreement

                                       11


               4.8.1.3. prepare, cause to be filed and use its best efforts to
cause to become effective with respect to the Collateral, or any part thereof,
such qualification statements or similar documents (including any offering
circular) as may be necessary to have such Collateral qualified or registered
under the securities laws of such other jurisdictions (including the applicable
state securities of "Blue Sky" law), and to obtain such Governmental Approvals
for the sale of such Collateral, as the Security Trustee may request in
connection with any such offering or sale;

               4.8.1.4. include in any such registration statement,
qualification statement or similar document all appropriate information relating
to the transaction or transactions in which the Security Trustee proposes to
offer or sell such Collateral;

               4.8.1.5. cause to be filed such pre-effective and post-effective
amendments to each such registration statement, qualification statement or
similar document as may be necessary to prevent any statement therein contained
from being untrue or misleading, and such filing, qualification or registration
to be kept effective for such period as the Security Trustee may deem
appropriate to facilitate the sale or other disposition of such Collateral;

               4.8.1.6. furnish the Security Trustee with such numbers of copies
of each such registration statement, qualification statement or similar
document, and any amendments thereto as the Security Trustee may request;

               4.8.1.7. furnish to the Security Trustee a legal opinion of
counsel acceptable to the Security Trustee as to such matters regarding such
offering or sale as the Security Trustee may reasonable request; and

               4.8.1.8. do such further acts and things as the Security Trustee
may deem necessary to advisable to effectuate the offering and sale by the
Security Trustee of such Collateral in compliance with Applicable Law.

          4.8.2. Each Pledgor agrees to indemnify and hold harmless the Secured
Parties and each underwriter (within the meaning of the Securities Act) acting
in the transaction, and each Person controlling (within the meaning of the
Securities Act) any Secured Party or underwriter, from and against any and all
claims, actions, liabilities, costs and expenses (including legal fees and
expenses) based upon or arising out of any actual or alleged untrue statement of
a material fact contained in any such registration statement, qualification
statement or similar document, or part thereof, or any actual or alleged
omission to state a material fact required to be stated in any such document, or
part thereof, or necessary to make the statements contained therein not
misleading; provided, however, that no Pledgor shall have any liability to any
Person under the foregoing indemnity on account of any actual or alleged untrue
or misleading statement contained in, or any actual or alleged omission from,
any information furnished in writing to such Pledgor by such Person specifically
for use in such document and included thereon in reliance therein.



                                Pledge Agreement

                                       12


          4.8.3. If the indemnification provided for in this Section 4.8. is
unavailable to or otherwise insufficient to hold harmless an indemnified party
hereunder in respect of any claims, actions, liabilities, costs or expenses
referred to herein, then each Pledgor, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such claims, actions, liabilities, costs or expenses in such
proportion as is appropriate to reflect the relative fault of such Pledgor, any
Secured Party and each underwriter in connection with the statements or
omissions that resulted in such claims, actions, liabilities, costs or expenses,
as well as any other relevant equitable considerations.

          4.8.4. Each Pledgor agrees that (i) exercise of registration and other
rights provided in this Section 4.8 is not required in connection with any
exercise of remedies under Article 5 of this Agreement, (ii) such rights may be
exercised or not exercised in the sole discretion of the Security Trustee and
(iii) any request for exercise of such rights may be withdrawn in whole or in
part at any time by the Security Trustee in its sole discretion.

                                   ARTICLE 5.

                    DEFAULT; RIGHTS AND REMEDIES ON DEFAULT

          Section 5.1. Remedies Upon Default. If upon or after the occurrence of
any Default, the Security Trustee elects to exercise remedies under this
Agreement (the occurrence of any such election or other event shall be referred
to as an "Acceleration"), then, whether or not all the Secured Obligations shall
have become immediately due and payable:

          5.1.1. In addition to all its other rights, powers and remedies under
this Agreement and Applicable Law, each Secured Parties shall have, and may
exercise, any and all of the rights, powers and remedies of any secured part
under the UCC, all of which rights, powers and remedies shall be cumulative and
not exclusive, to the extent permitted by Applicable Law.

          5.1.2. The Security Trustee shall have the right, all at the Security
Trustee's sole option and as the Security Trustee in its discretion may deem
necessary or advisable, to do any or all of the following:

               5.1.2.1. to foreclose the Security Interest by any available
judicial procedure or without judicial process; and

               5.1.2.2. to exercise any and all other rights, powers, privileges
and remedies of any owner of the Collateral, including rights of conversion,
exchange or subscription or other rights or upon the exercise by any Pledgor or
the Security Trustee of any right, power or privilege pertaining to the
Collateral, the right to deposit and deliver any and all of the Collateral to
any committee, depositary, transfer agent, registrar or other designated agency
upon such terms and conditions as the Security



                                Pledge Agreement

                                       13


Trustee may determine to be appropriate, all without liability except to account
for property actually received by it, but the Security Trustee shall have no
duty to the Pledgors to exercise any such right, power or privilege and shall
not be responsible for any failure to do so or delay in so doing.

               5.1.3. The Security Trustee shall have the right to sell or
otherwise dispose of all or any Collateral at public or private sale or sales,
with such notice as may be required by Section 5.3., in lots or in bulk, at any
exchange, over the counter or at any of the Security Trustee's offices or
elsewhere, for cash or on credit, with or without representations or warranties,
all as the Security Trustee, in its discretion, may deem advisable. The
Collateral need not be present at any such sales. If sale of all or any part of
the Collateral is made on credit or for future delivery, the Collateral so sold
may be retained by the Security Trustee until the sale price is paid by the
purchaser thereof, but the Secured Parties shall not incur any liability in case
any such purchaser shall fail to take up and pay for the Collateral so sold and,
in case of any such failure, such Collateral may be sold again upon like notice.
The Security Trustee shall not be obligated to make any sale of the Collateral
regardless of notice of sale having been given. The Security Trustee may
purchase all or any part of the Collateral at public or, if permitted by
Applicable Law, private sale, and in lieu of actual payment of the purchase
price, the Security Trustee may apply against such purchase price any amount of
the Secured Obligations. Each Pledgor agrees that any sale of Collateral
conducted by the Security Trustee in accordance with the foregoing provisions of
this Section and Section 5.2. shall be deemed to be a commercially reasonable
sale under Section 9-504 of the UCC.

               5.1.4. The Security Trustee shall not be required to register or
qualify any of the Collateral that constitutes securities under applicable state
or federal securities laws in connection with any sale or other disposition
thereof if such disposition is effected in a manner that complies with all
applicable federal and state securities laws. The Security Trustee shall be
authorized at any such disposition (if it deems it advisable to do so) to
restrict the prospective bidders or purchasers to persons who will represent and
agree that they are "accredited investors" or "qualified institutional buyers"
under Applicable Law and purchasing the Collateral for their own account for
investment and not with a view to the distribution or sale thereof. If any such
Collateral is sold at private sale, each Pledgor agrees that if such Collateral
is sold in a manner that the Security Trustee in good faith believes to be
reasonable under the circumstances then existing, then (A) the sale shall be
deemed to be commercially reasonable in all respects, (B) such Pledgor shall not
be entitled to a credit against the Secured Obligations in any amount in excess
of the purchase price, and (C) the Secured Parties shall not incur any liability
or responsibility to any Pledgor in connection therewith, notwithstanding the
possibility that a substantially higher price might have been realized at a
public sale. Each Pledgor recognizes that a ready market may not exist for such
Collateral if it is not regularly traded on a recognized securities exchange,
and that a sale by the Security Trustee of any such Collateral for an amount
substantially less than the price that might have been achieved had the
Collateral been



                                Pledge Agreement

                                       14


so traded may be commercially reasonable in view of the difficulties that may be
encountered in attempting to sell Collateral that is privately traded.

          Section 5.2. Application of Proceeds.

          5.2.1. Any cash proceeds received by the Security Trustee in respect
of any sale of, collection from, or other realization upon, all of any part of
the Collateral following the occurrence of an Acceleration or otherwise
(including insurance proceeds) may be held by the Security Trustee as Collateral
and/or then or at any time thereafter applied as provided in the Inter-Creditor
Agreement (or as otherwise determined by the Security Trustee if the
Inter-Creditor Agreement is no longer in effect).

          5.2.2. Each Pledgor and any other Person then obligated therefor shall
pay to the Security Trustee on demand any deficiency with regard to the Secured
Obligations that may remain after such sale, collection or realization of, from
or upon the Collateral.

          5.2.3. Payments received from any third party on account of any
Collateral shall not reduce the Secured Obligations until paid in cash to the
Security Trustee. The application of proceeds by the Security Trustee shall be
without prejudice to the Security Trustee's rights as against any Pledgor or
other Persons with respect to any Secured Obligations that may then be or remain
unpaid.

          5.2.4. If at any time after an Acceleration any Pledgor receives any
collections upon or other Proceeds of any Collateral, whether in the form of
cash, notes or otherwise, such Proceeds shall be received in trust for the
Secured Parties and such Pledgor shall keep all such Proceeds separate and apart
from all other funds and property so as to be capable of identification as the
property of the Secured Parties and promptly deliver such Proceeds to the
Security Trustee in the identical form received.

          Section 5.3. Notice. Unless the Collateral is perishable or threatens

market, the Security Trustee will send or otherwise make available to each
Pledgor reasonable notice of the time and place of any public sale or of the
time on or after which any private sale of any Collateral is to be made. Each
Pledgor agrees that any notice required to be given by the Security Trustee of a
sale or other disposition of Collateral, or any other intended action by the
Security Trustee, that is received in accordance with the provisions set forth
in Section 6.4. five days prior to such proposed action shall constitute
commercially reasonable and fair notice thereof to the Pledgers. 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. Each Pledgor hereby
waives any right to receive notice of any public or private sale of any
Collateral or other security for the Secured Obligations except as expressly
provided for in this Section.

                                    GENERAL

          Section 6.1. Security Trustee's Expenses, Including Attorneys' Fees.
Regardless of the occurrence of a Default or Default Occurrence, the Pledgors
jointly and severally agree to pay to the Security Trustee any and all advances,
charges, costs and expenses, including the fees and expenses of counsel and any
experts or agents, that the Security Trustee may incur in connection with (a)
the administration of this Agreement, (b) the creation, perfection or
continuation of the Security Interest or protection of its priority or the
Collateral, including the discharging of any prior or junior Lien or adverse
claim against the Collateral or any part thereof that is not permitted hereby or
by the Financing Documents, (c) the custody, preservation or sale of, collection
from, or other realization upon, any of the Collateral, (d) the exercise or
enforcement of any of the rights, powers or remedies of the Security Trustee
under this Agreement or under Applicable Law (including attorneys' fees and
expenses incurred by the Security Trustee in the collection of Collateral
deposited with the Security Trustee and amounts incurred in connection with the
operation, maintenance or foreclosure of the Security Interest) or any workout
or restructuring or insolvency or bankruptcy proceeding or (e) the failure by
any Pledgor to perform or observe any of the provisions hereof. All such amounts
and all other amounts payable hereunder shall be payable on demand, together
with interest at the Default Rate, from and including the due date to and
excluding the date of payment.

          Section 6.2. Amendments and Other Modifications. No amendment of any
provision of this Agreement (including a waiver thereof or consent relating
thereto) shall be effective unless the same shall be in writing and signed by
the Security Trustee. Any waiver or consent relating to any provision of this
Agreement shall be effective only in the specific instance and for the specific
purpose for which given. No notice to or demand on any Pledgor in any case shall
entitle such Pledgor to any other or further notice or demand in similar or
other circumstances.

          Section 6.3. Cumulative Remedies; Failure or Delay.

          The rights and remedies provided for under this Agreement are
cumulative and are not exclusive of any rights and remedies that may be
available to the Secured Parties under Applicable Law, the other Financing
Documents or otherwise. No failure or delay on the part of the Security Trustee
in the exercise of any power, right or remedy under this Agreement shall impair
such power, right or remedy or shall operate as a waiver thereof, nor shall any
single or partial exercise of any such power, right or remedy preclude other or
further exercise of such or any other power, right or remedy.

          Section 6.4. Notices, Etc. All notices and other communications under
this Agreement shall be in writing and shall be personally delivered or sent by
prepaid courier, by overnight, registered or certified mail (postage prepaid) or
by prepaid telex,

recipient thereof. Unless otherwise specified in a notice given in accordance
with the foregoing provisions of this Section 6.4, notices and other
communications shall be given to the parties hereto at their respective
addresses (or to their respective telex telecopier numbers) indicated on
Schedule 6.4.

          Section 6.5. Successors and Assigns. This Agreement shall be binding
upon and, subject to the next sentence, inure to the benefit of each Pledgor and
the Security Trustee and their respective successors and assigns. No Pledgor
shall assign or transfer any of its rights or obligations hereunder without the
prior written consent of the Security Trustee. The benefits of this Agreement
shall pass automatically with any assignment of the Secured Obligations (or any
portion thereof), to the extent of such assignment.

          Section 6.6. Payments Set Aside. Notwithstanding anything to the
contrary herein contained, this Agreement, the Secured Obligations and the
Security Interest shall continue to be effective or reinstated, as the case may
be, if at any time any payment, or any part thereof, of any or all of the
Secured Obligations is rescinded, invalidated, declared to be fraudulent or
preferential or otherwise required to be restored or returned by any Secured
Party in connection with any bankruptcy, reorganization or similar proceeding
involving any Pledgor, any other party liable with respect to the Secured
Obligations or otherwise, if the proceeds of any Collateral are required to be
returned by such Secured Party under any such circumstances, or if any Secured
Party elects to return any such payment or proceeds or any part thereof in its
sole discretion, all as though such payment had not been made or such proceeds
not been received. Without limiting the generality of the foregoing, if prior to
any such rescission, invalidation, declaration, restoration or return, this
Agreement shall have been cancelled or surrendered or the Security Interest or
any Collateral shall have been released or terminated in connection with such
cancellation or surrender, this Agreement and the Security Interest and such
Collateral shall be reinstated in full force and effect, and such prior
cancellation or surrender shall not diminish, discharge or otherwise affect the
obligations of the Pledgors in respect of the amount of the affected payment or
application of proceeds, the Security Interest or such Collateral.

          Section 6.7. Continuing Security Interest; Termination. This Agreement
shall create a continuing security interest in the Collateral and, except as
provided below, the Security Interest and all agreements, representations and
warranties made herein shall survive until, and this Agreement shall terminate
only upon, the indefeasible payment in full of the Secured Obligations.

          Notwithstanding anything in this Agreement or Applicable Law to the
contrary, the agreements of the Pledgors set forth in Sections 4.8.2 and 6.1
shall survive the payment of all other Secured Obligations and the termination
of this Agreement.

          Section 6.8. Choice of Forum

          6.8.1. Each of the Pledgors irrevocably agrees for the benefit of each
of the Beneficiaries that the courts of England shall have jurisdiction to hear
and determine any suit, action or proceeding, and to settle any disputes, which
may arise out of or in connection with this Agreement (and the other Financing
Documents) and, for such purposes, irrevocably submits to the jurisdiction of
such courts. Each of the Pledgors irrevocably agrees that the courts of the
State of New York and the courts of the United States of America in New York
shall have jurisdiction to hear and determine any suit, action or proceeding,
and to settle any disputes, which may arise out of or in connection with this
Agreement (and the other Financing Documents) and, for such purposes,
irrevocably submits to the jurisdiction of such courts. Each of the Pledgors
irrevocably waives any objection which it might now or hereafter have to the
courts referred to in this Section 6.8.1 being nominated as the forum to hear
and determine any suit, action or proceeding, and to settle any disputes, which
may arise out of or in connection with this Agreement and the Financing
Documents and agrees not to claim that any such court is not a convenient or
appropriate forum.

          IN ANY ACTION AGAINST ANY PLEDGOR, SERVICE OF PROCESS MAY BE MADE UPON
SUCH PLEDGOR OR BY DELIVERY OR BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT
REQUESTED, TO ITS ADDRESS INDICATED IN SCHEDULE 6.4, WHICH SERVICE SHALL BE
DEEMED SUFFICIENT FOR PERSONAL JURISDICTION AND SHALL BE DEEMED EFFECTIVE UPON
RECEIPT, IN THE CASE OF DELIVERY, AND 10 DAYS AFTER MAILING, IN THE CASE OF
MAILING. Each Pledgor hereby irrevocably appoints CT Corporation Systems (the
"Process Agent"), with offices on the date hereof in New York, New York as
Process Agent to receive for and on behalf of such Pledgor service of process in
the County of New York relating to this Agreement. SERVICE OF PROCESS IN ANY
ACTION OR PROCEEDING AGAINST ANY PLEDGOR MAY BE MADE ON THE PROCESS AGENT BY
REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT REQUESTED, OR BY ANY OTHER METHOD
OF SERVICE PROVIDED FOR UNDER APPLICABLE LAWS IN EFFECT IN THE STATE OF NEW
YORK, AND THE PROCESS AGENT IS HEREBY AUTHORIZED AND DIRECTED TO ACCEPT SUCH
SERVICE FOR AND ON BEAHLF OF SUCH PLEDGOR AND TO ADMIT SERVICE WITH RESPECT
THERETO. SUCH SERVICE UPON THE PROCESS AGENT SHALL BE DEEMED EFFECTIVE PERSONAL
SERVICE ON SUCH PLEDGOR, SUFFICIENT FOR PERSONAL JURISDICTION, 10 DAYS AFTER
MAILING, AND SHALL BE LEGAL AND BINDING UPON SUCH PLEDGOR FOR ALL PURPOSES,
NOTWITHSTANDING ANY FAILURE OF THE PROCESS AGENT TO MAIL COPIES OF SUCH LEGAL
PROCESS TO SUCH PLEDGOR, OR ANY FAILURE ON THE PART OF SUCH PLEDGOR TO RECEIVE
THE SAME. Each Pledgor confirms that it has instructed the Process Agent to mail
such Pledgor, upon service of process being made on the Process Agent pursuant
to this Section, a copy of the summons and complaint or other legal process
served upon it, be registered mail, return receipt

requested, at such Pledgor's address set forth in Schedule 6.4., or to such
other address as such Pledgor may notify the Process Agent in writing. Each
Pledgor agrees that it will at all time maintain a process agent to receive
service of process in the County of New York on its behalf with respect to this
Agreement. If for any reason the Process Agent or any successor thereto shall no
longer serve as such process agent or shall have changed its address without
notification thereof to the Beneficiaries, such Pledgor, immediately after
gaining knowledge thereof, irrevocably shall appoint a substitute process agent
acceptable to the Security Trustee in the County of New York and advise the
Security Trustee thereof.

          6.8.2. The submission to the jurisdiction of the courts referred to in
Section 6.8.1. shall not (and shall not be construed as to) limit the right of
the Beneficiaries or any of them to take proceedings against any of the Pledgors
in any other court of competent jurisdiction nor shall the taking of proceedings
in any one or more jurisdictions preclude the taking of proceedings in any other
jurisdiction (whether concurrently or not) if and to the extent permitted by
applicable law.

          Section 6.9. Waiver and Estoppel. Except as otherwise provided in this
Agreement, each Pledgor hereby waives: (a) presentment, protest, notice of
dishonor, release, compromise, settlement, extension or renewal and any other
notice of or with respect to the Secured Obligations and hereby ratifies and
confirms whatever the Security Trustee may do in this regard; (b) notice prior
to taking possession or control of any Collateral; (C) any bond or security that
might be required by any court prior to allowing the Security Trustee to
exercise any of their rights, powers or remedies; (d) the benefit of all
valuation, appraisement, redemption and exemption laws; (e) any rights to
require marshalling of the Collateral upon any sale or otherwise to direct the
order in which the Collateral shall be sold; (f) any set-off; and (g) any rights
to require the Security Trustee to proceed against any Person, proceed against
or exhaust any Collateral or any other security interests or guaranties or
pursue any other remedy in the Security Trustee power, or to pursue any of such
rights in particular order or manner, and any defenses arising by reason of any
disability or defense of any Person.

          Section 6.10. Nature of Agreement. This Agreement is independent of
and not in consideration of or contingent upon the liability of any Borrower or
any other Person and foreclosure or other action may be taken against all or any
Collateral and a separate action or actions may be brought and prosecuted
against any Pledgor, whether or not any foreclosure or other action is taken
with respect to any other collateral or action is brought or prosecuted against
any Borrower or any other obligor or whether any Borrower or any other obligor
is joined in any such action or actions. This Agreement shall be construed as
continuing, absolute and unconditional without regard to:

          6.10.1. the legality, validity or enforceability of the Credit
Agreement, the U.S. Loan Notes or any other Financing Document, any of the

other right or remedy of such Pledgor is extinguished or impaired), from time to
time to:

or terminate, release, compromise, subordinate, extend, accelerate or otherwise
change the amount or time, manner or place of payment of, or rescind any demand
for payment or acceleration of, the Secured Obligations or any part thereof
(including increasing or decreasing the rate of interest thereon), or otherwise
amend the terms and conditions of the Credit Agreement, the U.S. Loan Notes, any
other Financing Document or any provision thereof;

          6.11.2. take and hold other collateral from any Borrower or any other
Person, perfect or refrain from perfecting a Lien on such other collateral, and

          6.11.3. exercise in such manner and order as it elects in its sole

Agreement, any guaranty or the Secured Obligations;

          6.11.5. accept partial payments on the Secured Obligations and apply

discretion, whether or not such Secured Obligations are otherwise secured or
guaranteed;

any payments or recoveries received by such Secured Party in respect of any
Secured Obligations or other collateral; and

          6.11.7. otherwise deal with any Borrower, any other obligor and any
other collateral as such Secured Party may elect in its sole discretion.

consequential or punitive damages in respect of any claim for breach of contract
or under any other theory of liability arising out of or related to the
transactions contemplated by this Agreement and the other Financing Documents,
or any act, omission or event occurring in connection therewith; and each
Pledgor hereby waives, release and agrees not to sue upon any claim for any such
damages, whether or not accrued and whether or not known or suspected to exist
in its favor.

          Section 6.15. WAIVER OF TRIAL BY JURY. EACH PLEDGOR AND THE SECURITY
TRUSTEE WAIVE THE RIGHT TO A TRIAL BY JURY IN ANY ACTION UNDER THIS AGREEMENT OR
ANY OTHER FINANCING DOCUMENT OR ANY ACTION ARISING OUT OF THE TRANSACTIONS

          Encumbrance) whether in any such case ranking in priority to or pari
          passu with or after the security created by this Guarantee and
          Debenture save to the extent permitted or required under the Credit
          Agreement or the US Loan Notes Instrument; or

     (b)  sell, discount, factor, transfer, lease, lend or otherwise dispose of,
          whether by means of one or a number of transactions related or not and
          whether at one time or over a period of time, the whole or any part of
          its undertaking or assets except as permitted under the Credit
          Agreement or the US Loan Notes Instrument.

5.   FURTHER ASSURANCE

5.1  The Chargor hereby applies to the Chief Land Registrar for the registration
     against the registered titles specified in Schedule 2 of the following:

     (a)  a restriction in the following terms:

          "except under an order of the Registrar no charge or other security
          interest is to be registered or noted without the consent of the
          proprietor for the time being of charge number [ ]";




     (b)  a notice that under the provisions of this Guarantee and Debenture the
          Secured Parties are under an obligation to make further advances.

5.2  The Chargor shall from time to time and to the extent it is able to do so
     without breaching any provision of any other agreement binding upon it, at
     the request of the Security Trustee and at the Chargor's cost, execute in
     favour of the Security Trustee, or as it may direct, such further or other
     legal assignments, transfers, mortgages, charges or other documents as in
     any such case the Security Trustee shall stipulate over the Chargor's
     estate or interest in any property or assets of whatsoever nature or tenure
     and wheresoever situate, for the purpose of more effectively providing
     security to the Security Trustee on the terms of, or as intended to be
     created by, this Guarantee and Debenture for the payment or discharge of
     the Secured Obligations. Without prejudice to the generality of the
     foregoing, such assignments, transfers, mortgages, charges or other
     documents shall be in such form as the Security Trustee shall stipulate and
     may contain provisions such as are herein contained or provisions to the
     like effect and/or such other provisions of whatsoever kind as the Security
     Trustee shall consider requisite for the improvement or perfection of the
     security constituted by or pursuant to this Guarantee and Debenture. The
     obligations of the Chargor under this Clause shall be in addition to and
     not in substitution for the covenants for further assurance deemed to be
     included herein by virtue of the Law of Property (Miscellaneous Provisions)
     Act 1994.

5.3  The Chargor shall immediately after the execution of this Guarantee and
     Debenture (or upon becoming possessed thereof at any time hereafter)
     deposit with the Security Trustee all deeds, certificates and other
     documents constituting or evidencing title to its real property comprised
     within the Charged Property or any part thereof and to any of the assets
     and rights charged under Clause 3.1(e).

6.   DEBTS AND CREDIT BALANCES

6.1  With reference to the Debts the Chargor shall collect in the Debts and
     shall, in the absence of specific written instructions from the Security
     Trustee to the contrary, pay into the Chargor's current account with the
     Security Trustee and/or if so directed by the Security Trustee into a
     special or specifically designated account with the Security Trustee either
     in the name of the Chargor or the Security Trustee or into such other
     account as the Security Trustee may direct all moneys which the Chargor may
     receive in respect of the Debts and shall not without the prior consent in
     writing of the Security Trustee sell, factor, discount or otherwise charge
     or assign the Debts in favour of any other person or purport to do so and
     the Chargor shall if called upon to do so by the Security Trustee from time
     to time execute legal assignments of the Debts to the Security Trustee in
     forms approved by the Security Trustee.

6.2  Prior to the security hereby created becoming enforceable, in the absence
     of any written directions to the contrary from the Security Trustee to pay
     such moneys into any other account, any moneys in respect of the Debts
     received by the Chargor and paid into any current account with the Security
     Trustee in accordance with the




     requirements of Clause 6.1 hereof shall upon being paid into such current
     account be released from the fixed charge created by Clause 3.1(d) hereof
     and shall become subject to the floating charge created by Clause 3.1(i) .
     Such release from the fixed charge shall not affect and shall be entirely
     without prejudice to the continuance of the said fixed charge on all other
     Debts of the Chargor outstanding from time to time and on all moneys which
     the Chargor receives in respect thereof.

6.3  With reference to the Credit Balances the Chargor agrees to inform the
     Security Trustee as soon as any Credit Balance with any third party comes
     into existence and if so directed by the Security Trustee the Chargor shall
     transfer any such Credit Balance into the Chargor's account with the
     Security Trustee or into a specifically designated account with the
     Security Trustee in the name of the Chargor or the Security Trustee or in
     the joint names of the Chargor and the Security Trustee and shall not
     without the prior consent in writing of the Security Trustee sell or
     otherwise charge or assign any Credit Balance in favour of any person or
     purport to do so.

7.   CONVERSION OF FLOATING CHARGE AND AUTOMATIC CRYSTALLISATION

7.1  If, at any time, the Security Trustee believes that any assets of the
     Chargor are in danger of being seized or sold under any form of distress,
     execution or other similar process then without prejudice to the provisions
     of Clause 7.2 the Security Trustee may, by notice in writing to the
     Chargor, convert the floating charge created by this Guarantee and
     Debenture into a fixed charge in relation to the assets specified in such
     notice (which assets need not be exclusively those assets which are in
     danger of seizure or sale) and the Security Trustee shall further be
     entitled (but not bound) to take possession of or appoint a Receiver of
     such assets.

7.2  If the Chargor charges, pledges or otherwise encumbers (whether by way of
     fixed or floating security) any of the property, assets and income
     comprising the Floating Charge Property or attempts so to do without the
     prior consent in writing of the Security Trustee or if any creditor or
     other person levies any distress, execution, sequestration or other process
     against any of the said property, assets and income then in the absence of
     any notice or other action by the Security Trustee pursuant to Clause 7.1
     the floating charge hereby created shall automatically operate as a fixed
     charge forthwith upon the occurrence of such event, but only in respect of
     the assets, property or income in respect of which or against which such
     action was taken.

8.   INSURANCE

8.1  The Chargor shall at all times during the subsistence of the security
     constituted by or pursuant to this Guarantee and Debenture comply with all
     covenants, undertakings and conditions as to insurance of any part of the
     Charged Property imposed by the terms of any lease, agreement for lease or
     any tenancy under which the Chargor




     derives its estate or interest therein and, subject to the foregoing and so
     far as not inconsistent with the said terms, the Chargor shall at all such
     times:

     (a)  cause all buildings, trade and other fixtures and all plant,
          machinery, vehicles, computers and office and other equipment and all
          stock in trade forming part of the Charged Property to be insured and
          to be kept insured in such insurance office, in such amounts and
          against such risks as the Security Trustee may require from time to
          time, but otherwise in such insurance office of repute as shall have
          been selected by the Chargor or with Lloyd's underwriters on the
          equivalent basis as insurances are maintained by prudent companies
          carrying on businesses comparable with that of the Chargor and on a
          comparable scale as regards the property and assets insured, the
          insured risks and the classes of risk to be covered and the amount of
          the insurance cover;

     (b)  cause the interest of the Security Trustee and the other Secured
          Parties in all parts of the Charged Property that are for the time
          being insured otherwise than in the joint names of the Security
          Trustee and the Chargor to be noted by endorsement on the policy or
          policies of insurance relating thereto;

     (c)  duly and punctually pay all premiums and other moneys due and payable
          under all such insurances as aforesaid and promptly upon request by
          the Security Trustee produce to the Security Trustee the premium
          receipts or other evidence of the payment thereof; and

     (d)  on demand by the Security Trustee, deposit all policies and other
          contracts of insurance relating to the Charged Property or any part
          thereof with the Security Trustee or produce the same to the Security
          Trustee for inspection.

8.2  If default shall be made by the Chargor in complying with Clause 8.1 the
     Security Trustee may but shall not be obliged to effect or renew any such
     insurance as is mentioned in that Clause either in its own name or in its
     name and that of the Chargor jointly or in the name of the Chargor with an
     endorsement of the Security Trustee's interest. The moneys expended by the
     Security Trustee on so effecting or renewing any such insurance shall be
     reimbursed by the Chargor to the Security Trustee on demand and until so
     reimbursed shall carry interest at the rate of two (2) per cent. above the
     Security Trustee's Rate from time to time from the date of payment to the
     date of reimbursement (after as well as before any judgment).

8.3  All claims and moneys received or receivable under any such insurances as
     aforesaid shall (subject to the rights and claims of any lessor or landlord
     of any part of the Charged Property) at the direction of the Security
     Trustee be applied in making good the loss or damage in respect of which
     the same has been received or in or towards the discharge of the Secured
     Obligations.

9.   UNDERTAKINGS BY THE CHARGOR




9.1  The Chargor hereby undertakes with the Security Trustee and the Secured
     Parties that it will at all times while there shall subsist any security
     constituted by or pursuant to this Guarantee and Debenture:

     (a)  keep all buildings, trade and other fixtures, fixed and other plant
          and machinery forming part of the Charged Property in good and
          substantial repair and permit the Security Trustee, its officers,
          employees and agents free access at all reasonable times to view the
          state and condition thereof, provided that the Security Trustee shall
          have given the Chargor reasonable prior notice of its desire to
          exercise its rights under this sub-Clause and requested access
          accordingly;

     (b)  preserve, maintain and renew as and when necessary all copyrights,
          licences, patents, trade marks and other rights required in connection
          with its business:

     (c)  observe and perform all covenants and stipulations from time to time
          affecting its freehold or leasehold property or the mode of user or
          enjoyment of the same and not without the prior consent in writing of
          the Security Trustee enter into any onerous or restrictive obligations
          affecting any such property or make any structural or material
          alteration thereto or do or suffer to be done on any such property
          anything which is "development" as defined in section 55 of the Town
          and Country Planning Act 1990 nor do or suffer or omit to be done any
          act, matter or thing whereby any provision of any Act of Parliament,
          order or regulation from time to time in force affecting any such
          property is infringed;

     (d)  observe and perform all covenants reserved by or contained in any
          lease, agreement for lease or tenancy agreement under which any part
          of the Charged Property may be held and will not, without the consent
          of the Security Trustee vary, surrender, cancel, assign or otherwise
          dispose of or permit to be forfeited any leasehold interest forming
          part of the Charged Property or agree any rent review;

     (e)  not without the prior consent of the Security Trustee part with
          possession of the whole or any part of, or confer on any other person
          any right or licence to occupy, or grant any licence to assign or
          sub-let land or buildings forming part of the Charged Property;

     (f)  not without the prior written consent of the Security Trustee allow
          any person other than itself to be registered under the Land
          Registration Act 1925 as proprietor of the Charged Property or any
          part thereof or create or permit to arise any overriding interest (as
          specified in section 70(1) of the Land Registration Act 1925)
          affecting such property and the reasonable costs incurred by the
          Security Trustee of lodging a caution against registration of the
          title to such property or a land charge (if unregistered) or any part
          thereof, shall be an expense properly incurred in relation to this
          security; and




     (g)  indemnify the Security Trustee (and as a separate covenant any
          Receiver or Receivers appointed by it) against all existing and future
          rents, taxes, rates, duties, fees, renewal fees, charges, assessments,
          impositions and outgoings whatsoever (whether imposed by deed or
          statute or otherwise and whether in the nature of capital or revenue
          and even though of a wholly novel character) which now or at any time
          during the continuance of the security constituted by or pursuant to
          this Guarantee and Debenture are properly payable in respect of the
          Charged Property or any part thereof or by the owner or occupier
          thereof.

9.2  If any such sums as are referred to in Clause 9.1(g) shall be paid by the
     Security Trustee (or any Receiver or Receivers) the same shall be
     reimbursed by the Chargor to the Security Trustee on demand and until so
     reimbursed shall bear interest at the rate of two (2) per cent. above the
     Security Trustee's Rate from time to time from the date of payment to the
     date of reimbursement (after as well as before any judgment).

10.  POWERS OF THE SECURITY TRUSTEE

10.1 At any time after the making of a Demand, or if requested by the Chargor,
     the Security Trustee may exercise without further notice and without any of
     the restrictions contained in section 103 of the Law of Property Act 1925,
     whether or not it shall have appointed a Receiver, all the powers conferred
     on mortgagees by the Law of Property Act 1925 and all the powers and
     discretions conferred by this Guarantee and Debenture.

10.2 The statutory powers of leasing, letting, entering into agreements for
     leases or lettings and accepting and agreeing to accept surrenders of
     leases conferred by sections 99 and 100 of the said Act shall not be
     exercisable by the Chargor in relation to any part of the Charged Property
     without the prior written consent of the Security Trustee. In addition to
     such statutory powers the Security Trustee shall have power after serving
     the notice referred to in Clause 10.1 to lease or make agreements for
     leases at a premium or otherwise and accept surrenders of leases and
     generally without any restriction on the kinds of leases and agreements for
     leases that the Security Trustee may make and generally without the
     necessity for the Security Trustee to comply with any restrictions imposed
     by or the other provisions of the said sections 99 and 100. The Security
     Trustee may delegate such powers to any person and no such delegation shall
     preclude the subsequent exercise or such powers by the Security Trustee
     itself or preclude the Security Trustee from making a subsequent delegation
     thereof to some other person and any such delegation may be revoked.

10.3 The restriction on the right of consolidating mortgage securities contained
     in section 93 of the Law of Property Act 1925 shall not apply to this
     Guarantee and Debenture.




10.4 So far as permitted by law, neither the Security Trustee nor any Receiver
     shall by reason of it or any Receiver entering into possession of any part
     of the Charged Property when entitled so to do be liable to account as
     mortgagee in possession or be liable for any loss or realisation or for any
     default or omission for which a mortgagee in possession might be liable.

11.  APPOINTMENT OF RECEIVER

11.1 At any time after the making of a Demand, or if requested by the Chargor or
     after the application to the court for an administration order in relation
     to the Chargor under the Insolvency Act 1986 the Security Trustee may
     appoint one or more persons to be a Receiver or Receivers of the Charged
     Property or any part thereof.

11.2 Subject to Section 45 of the Insolvency Act 1986, the Security Trustee may
     remove any Receiver previously appointed hereunder, and appoint another
     person or other persons as Receiver or Receivers, either in the place of a
     Receiver so removed or who has otherwise ceased to act or to act jointly
     with a Receiver or Receivers previously appointed hereunder.

11.3 If at any time and by virtue of any such appointment(s) any two or more
     persons shall hold office as Receivers of the same assets or income, each
     one of such Receivers shall be entitled (unless the contrary shall be
     stated in any of the deed(s) or other instrument(s) appointing them) to
     exercise all the powers and discretions hereby conferred on Receivers
     individually and to the exclusion of the other or others of them.

11.4 Every such appointment or removal, and every delegation, appointment or
     removal by the Security Trustee in the exercise of any right to delegate
     its powers or to remove delegates herein contained, may be made in writing
     under the hand of any officer of the Security Trustee.

11.5 Every Receiver shall have:

     (a)  all the powers conferred by the Law of Property Act 1925 on mortgagees
          in possession and receivers appointed under that Act:

     (b)  all the powers specified in Schedule1of the Insolvency Act 1986; and

     (c)  all the powers of the Security Trustee hereunder.

11.6 In making any sale or other disposal of any of the Charged Property in the
     exercise of their respective powers, the Receiver or the Security Trustee
     may accept, as and by way of consideration for such sale or other disposal,
     cash, shares, loan capital or other obligations, including without
     limitation consideration fluctuating according to or dependent upon profit
     or turnover and consideration the amount whereof is to be determined by a
     third party. Any such consideration may be receivable in a lump sum or by
     instalments.




11.7 All moneys received by any Receiver appointed under this Guarantee and
     Debenture shall be applied in the following order: (1) in the payment or
     the costs, charges and expenses of and incidental to the Receiver's
     appointment and the payment of his remuneration; (2) in the payment and
     discharge of any outgoings paid and liabilities incurred by the Receiver in
     the exercise of any of the powers of the Receiver; (3) in providing for the
     matters (other than the remuneration of the Receiver) specified in the
     first three paragraphs of Section 109(8) of the Law of Property Act 1925;
     (4) in or towards payment of any debts or claims which are required by law
     to be paid in preference to the Secured Obligations but only to the extent
     to which such debts or claims have such preference; (5) in or towards the
     satisfaction of the Secured Obligations in accordance with the terms of the
     Intercreditor Agreement, and (6) any surplus shall be paid to the Chargor
     or other person entitled thereto. The provisions of this Clause and Clause
     11.9 shall take effect as and by way of variation and extension to the
     provisions of the said Section 109(8), which provisions as so varied and
     extended shall be deemed incorporated herein.

11.8 Every Receiver shall be the agent of the Chargor which shall be solely
     responsible for his acts and defaults and for the payment of his
     remuneration.

11.9 Every Receiver shall be entitled to remuneration for his services at a rate
     to be fixed by agreement between him and the Security Trustee (or, failing
     such agreement, to be conclusively fixed by the Security Trustee)
     commensurate with the work and responsibilities involved upon the basis of
     charging from time to time adopted in accordance with his current practice
     or the current practice of his firm and without being limited to the
     maximum rate specified in section 109(6) of the Law of Property Act 1925.

     (a)  the Security Trustee;

     (b)  each and every person to whom the Security Trustee shall from time to
          time have delegated the exercise of the power of attorney conferred by
          this Clause; and

     (c)  any Receiver appointed hereunder and for the time being holding office
          as such;

     jointly and also severally to be its attorney or attorneys and in its name
     and otherwise on its behalf to do all acts and things and to sign, seal,
     execute, deliver, perfect and do all deeds, instruments, documents, acts
     and things which may be required for carrying out any obligation imposed on
     the Chargor by or pursuant to this Guarantee and Debenture (including but
     not limited to the obligations of the Chargor under Clause 5.1 and the
     statutory covenant referred to in such Clause) and, following the making of
     a Demand, for carrying any sale, lease or other dealing by the Security
     Trustee or such Receiver into effect, for conveying or transferring



     any legal estate or other interest in land or other property or otherwise
     howsoever, for getting in the Charged Property, and generally for enabling
     the Security Trustee and the Receiver to exercise the respective powers
     conferred on them by or pursuant to this Guarantee and Debenture or by law.
     The Security Trustee shall have full power to delegate the power conferred
     on it by this Clause, but no such delegation shall preclude the subsequent
     exercise of such power by the Security Trustee itself or preclude the
     Security Trustee from making a subsequent delegation thereof to some other
     person; any such delegation may be revoked by the Security Trustee at any
     time.

12.2 The power of attorney hereby granted is as regards the Security Trustee,
     its delegates and any such Receiver (and as the Chargor hereby
     acknowledges) granted irrevocably and for value as part of the security
     constituted by this Guarantee and Debenture to secure proprietary interests
     in and the performance of obligations owed to the respective donees within
     the meaning of the Powers of Attorney Act 1971.

13.  PROTECTION OF PURCHASERS

     No purchaser or other person dealing with the Security Trustee or its
     delegate or any Receiver appointed hereunder shall be bound to see or
     enquire whether the right of the Security Trustee or such Receiver to
     exercise any of its or his powers has arisen or become exercisable or be
     concerned to see whether any such delegation by the Security Trustee shall
     have lapsed for any reason or been revoked.

14.  CONSOLIDATION OF ACCOUNTS AND SET-OFF

     In addition to any general lien or similar rights to which they may be
     entitled by operation of law, each of the Secured Parties shall have the

     consolidate all or any of the Chargor's then existing accounts with and
     liabilities to each of such Secured Parties and to set off or transfer any
     sum or sums standing to the credit of any one or more of such accounts in
     or towards satisfaction of any of the liabilities of the Chargor to each of
     such Secured Parties on any other account or in any other respect. The
     liabilities referred to in this Clause may be actual, contingent, primary,
     collateral, several or joint liabilities, and the accounts, sums and
     liabilities referred to in this Clause may be denominated in any currency.

     Obligations the Security Trustee may, in its sole discretion, convert any
     moneys received, recovered or realised in any currency under this Guarantee
     and Debenture (including the proceeds of any previous conversion under this
     Clause) from their existing currency of denomination into any other
     currency in which the Secured Obligations are

     Security Trustee thinks fit.

     subsequent charge or other interest affecting any part of the Charged

     Parties may open a new account or accounts with the Chargor. If any of the
     Secured Parties do not open a new account or accounts they shall
     nevertheless be treated as if they had done so at the time when the notice
     was, or was deemed to be, received and as from that time all payments made
     to the Secured Parties shall be credited or be treated as having been
     credited to the new account or accounts and shall not operate to reduce the

     received or was deemed to have received such notice.

19.  CONTINUING SECURITY

     continuing and shall not be considered as satisfied or discharged by any
     intermediate payment or settlement of the whole or any part of the Secured
     Obligations and shall be binding until all the Secured Obligations have
     been discharged in full to the satisfaction of the Security Trustee and all
     of the Secured Parties have ceased to have any obligation whether actual or
     contingent to make any credit or accommodation available to any company
     within the Group under or pursuant to the Financing Documents.

20.  REMEDIES CUMULATIVE ETC.

20.1 The rights, powers and remedies provided in this Guarantee and Debenture
     are cumulative and are not, nor are they to be construed as, exclusive of
     any rights, powers or remedies provided by law or otherwise.

20.2 No failure on the part of the Security Trustee to exercise, or delay on its
     part in exercising, any of its respective rights, powers and remedies
     provided by this Guarantee and Debenture or by law (collectively the
     "Rights") shall operate as a waiver thereof, nor shall any single or
     partial waiver of any of the Rights preclude any further or other exercise
     of that one of the Rights concerned or the exercise of any other of the
     Rights.

20.3 The Chargor hereby agrees to indemnify the Security Trustee, the Secured
     Parties and any Receiver against all losses, actions, claims, costs,
     charges, expenses and liabilities incurred by the Security Trustee, the
     Secured Parties and by any Receiver (including any substitute delegate
     attorney as aforesaid) in relation to this Guarantee and Debenture or the
     Secured Obligations (including, without limitation, the costs, charges and
     expenses incurred in the carrying of this Guarantee and Debenture into
     effect or in the exercise of any of the rights, remedies and powers
     conferred hereby or in the perfection or enforcement of the security
     constituted hereby or pursuant




     hereto or in the perfection or enforcement of any other security for or
     guarantee in respect of the Secured Obligations) or occasioned by any
     breach by the Chargor of any of its covenants or obligations under this
     Guarantee and Debenture. The Chargor shall so indemnify the Security
     Trustee, the Secured Parties and any Receiver on demand and shall pay
     interest on the sum demanded at the rate per annum of two (2) per cent.
     above the Security Trustee's Rate from time to time from the date on which
     the same were demanded by the Security Trustee, any Secured Parties or any
     Receiver, as the case may be, and any sum so demanded together with any
     interest, shall be a charge upon the Charged Property in addition to the
     moneys hereby secured.

21.  PROVISIONS SEVERABLE

     Every provision contained in this Guarantee and Debenture shall be
     severable and distinct from every other such provision 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 the remaining
     such provisions shall not in any way be affected thereby.

22.  THE SECURITY TRUSTEE'S DISCRETION

22.1 Save where expressly stated to the contrary herein, any liberty or power
     which may be exercised or any determination which may be made hereunder by
     the Security Trustee may be exercised or made in the absolute and
     unfettered discretion of the Security Trustee which shall not be under any
     obligation to give reasons therefor.

22.2 A certificate by an officer of the Security Trustee as to any sums payable
     to the Security Trustee hereunder shall, save in the case of manifest
     error, be conclusive and binding.

     and no consent to any departure by the Chargor therefrom shall in any event
     be effective unless the same shall be in writing and signed or approved in
     writing 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.

     time to time (including, without limitation, any increase in the amount of
     the Secured Obligations).

26.  TRUST

     The Security Trustee shall hold the benefit of the covenants, mortgages and
     charges given by the Chargor hereto upon trust for the Secured Parties.

27.  ASSIGNMENT

     and Debenture to any person to whom all or any part of its rights, benefits
     and obligations under the Credit Agreement or the US Loan Notes, as the
     case may be, are assigned or transferred in accordance with the provisions
     of the Credit Agreement or the US Loan Notes, as the case may be, and the
     expression "the Security Trustee" wherever used herein shall be deemed to
     include the assignees and other successors, whether immediate or
     derivative, of the Security Trustee, who shall be entitled to enforce and
     proceed upon this Guarantee and Debenture in the same manner as if named
     herein. The Security Trustee shall be entitled to disclose any information

     effect until all moneys, obligations and liabilities referred to in Clause
     2 of this Guarantee and Debenture have been paid, discharged or satisfied
     in full notwithstanding the liquidation or other incapacity or any change
     in the constitution of any company with the Group or in the name and style
     of any of them or any settlement of account or other mater whatsoever.

1.2  This Guarantee is in addition to and shall not merge with or otherwise
     prejudice or affect or be prejudiced by any other right, remedy, guarantee,
     indemnity or security and may be enforced without first having recourse to
     the same or any other bill, note, mortgage, charge, pledge or lien now or
     hereafter held by or available to the Security Trustee or the other Secured
     Parties.

1.3  Notwithstanding that this Guarantee ceases to be continuing for any reason
     whatever the Security Trustee and any of the other Secured Parties may
     continue any accounts of any company within the Group or open one or more
     new accounts and the liability of the Chargor hereunder shall not in any
     manner be reduced or affected by any subsequent transactions or receipts or
     payments into or out of any such accounts.

1.4  If any purported obligation or liability of any company within the Group to
     any of the Secured Parties which if valid would have been the subject of
     this Guarantee is not or ceases to be valid or enforceable against any
     company within the Group on any ground whatsoever whether or not known to
     the Secured Parties including but not limited to any defect in or want of
     powers of any company within the Group or irregular exercise thereof or
     lack of authority by any person purporting to act on behalf of any company
     within the Group or any legal or other limitation (whether under the
     Limitation Acts or otherwise), disability, incapacity or any change in the
     constitution of or any amalgamation, reconstruction or liquidation of any
     company within the Group, the Chargor shall nevertheless be liable to the
     Secured parties in respect of that purported obligation or liability as if
     the same were fully valid and enforceable and the Chargor was the principal
     debtor in respect thereof. The Chargor hereby agrees to keep the Secured
     Parties fully indemnified against all damages, loss, costs and expenses
     arising from any failure of any company within the Group to carry out any
     such purported obligation or liability.

1.5  The liability of the Chargor shall not be affected nor shall this Guarantee
     and Debenture be discharged or diminished by reason of:

     (a)  any present or future bill, note guarantee, indemnity, mortgage,
          charge, pledge, lien or other security or right or remedy held by or
          available to the Secured Parties becoming wholly or in part void,
          voidable or unenforceable on any ground whatsoever or by the Secured
          Parties from




          time to time dealing with, exchanging, varying, realising, releasing
          or failing to perfect or enforce any of the same; or

     (b)  the Secured parties compounding with, discharging, releasing or
          varying the liability of or granting any time, indulgence or
          concession to any company within the Group or any other person or
          renewing, determining, varying or increasing any bill, promissory note
          or other negotiable instrument, accommodation, facility or transaction
          in any manner whatsoever or concurring in, accepting or varying any
          compromise, arrangement or settlement or omitting to claim or enforce
          payment from any company within the Group or any other person; or

     (c)  any act or omission which would have discharged or affected the
          liability of the Chargor had it been principal debtor instead of
          guarantor or by anything done or omitted which bur for this provision
          might operate to exonerate the Chargor.

1.6  The Chargor warrants to the Secured Parties that it has not taken or
     received and undertakes that it will not take or receive the benefit of any
     security from any company within the Group in connection with this
     Guarantee and Debenture. If any such security is taken the Chargor hereby
     declares that such security and all moneys at any time received in respect
     thereof shall be held on trust for the Secured Parties and as security for
     the liabilities of the Chargor under this Guarantee.

1.7  The Chargor hereby agrees to pay interest to the Security Trustee for the
     account of the Secured Parties on all sums demanded under this Guarantee
     and Debenture from the date of demand until actual payment (as well after
     as before any judgment) at the rate of two (2) per cent. above the Security
     Trustee's Rate calculated on a day to day basis. Such interest shall be
     compounded monthly in accordance with the usual practice of the Security
     Trustee but without prejudice to the right of the Security Trustee to
     require payment of such interest.

1.8  Until the Secured Obligations have been paid, discharged or satisfied in
     full, the Chargor hereby waives all rights of subrogation and indemnity
     against any company within the Group and agrees not to share in any
     security held or moneys received by the Security Trustee or any other
     Secured Party on account of the Secured Obligations or (unless so
     instructed by the Security Trustee) to claim or prove in competition with
     the Secured Parties in the liquidation of any company within the Group in
     respect of any moneys paid by the Chargor to the Security Trustee or any
     other Secured Party under this Guarantee and Debenture. If the Chargor
     receives any payment or other benefit or exercises any set-off or
     counter-claim or otherwise acts in breach of this Clause anything so
     received and any benefit derived directly or indirectly by the Chargor
     therefrom shall be held in trust for the Secured Parties and as security
     for the liabilities of the Chargor under this Guarantee and Debenture.

1.9  Any money received in connection with this Guarantee and Debenture may be
     placed to the credit of a suspense account with a view to preserving the
     right of each of the Secured Parties to prove for the whole of its claim
     against any company within the Group or any other person liable or may be
     applied by the Secured Parties




     in or towards satisfaction of such of the moneys, obligations or
     liabilities of the Chargor under this Guarantee and Debenture as the
     Security Trustee may from time to time conclusively determine.

1.10 Any release, discharge or settlement between the Chargor and the Security
     Trustee shall be conditional upon no security disposition or payment to the
     Secured Parties by any company within the Group or any other person being
     void, set aside or ordered to be refunded pursuant to any enactment or law
     relating to bankruptcy, liquidation or insolvency or for any reason
     whatever and if such condition shall not be fulfilled the Security Trustee
     shall be entitled to enforce this Guarantee and Debenture subsequently as
     if such release, discharge or settlement had not occurred and any such
     payment had not been made.

1.11 Unless and until the Secured Parties are satisfied in their absolute
     discretion as to the solvency of the Chargor the Secured Parties shall be
     entitled to retain any security constituted by or pursuant to Clause 3 of
     this Guarantee and Debenture for a period of up to six months after the
     payment, discharge or satisfaction of all moneys, obligations and
     liabilities that are or may become due, owing or incurred to or in favour
     of the Secured Parties from each company within the Group or the Chargor
     and notwithstanding any such payment, discharge or satisfaction, in the
     event of an act of bankruptcy by or the commencement of winding-up of the
     person making such payment or effecting such discharge or satisfaction at
     any time within the said period of six months, the Security Trustee shall
     be entitled to retain any such security for such further period as the
     Security Trustee may determine.

1.12 If this Guarantee is determined or called in by demand made by the Security
     Trustee, then the Secured Parties may open a new account or accounts with
     any or all companies within the Group; if the Secured Parties do not open a
     new account or accounts they shall nevertheless be treated as if they had
     done so at the time of determination or calling in and as from that time
     all payments made to the Secured Parties shall be credited or be treated as
     having been credited to the new account or accounts and shall not operate
     to reduce the amount for which this Guarantee is available as security at
     that time.

1.13 The Security Trustee shall not be obliged before taking steps to enforce
     this Guarantee:

     (a)  to take action or obtain judgment in any court against any company
          within the Group or any other person; or

     (b)  to make or file any claim in a bankruptcy or liquidation of any
          company within the Group or any other person; or

     (c)  to make, enforce or seek to enforce any claim against any company
          within the Group or any other person under any security or other
          document, agreement or arrangement.

1.14 All sums due and payable by the Chargor under this Guarantee and Debenture
     shall be made in full without set-off or counter-claim and free and clear
     of and (subject as



     provided in the next sentence) without deduction for or on account of any
     future or present Taxes. If:

     (a)  the Chargor is required by any law to make any deduction or
          withholding from any sum payable by the Chargor to the Security
          Trustee hereunder; or

     (b)  the Security Trustee or any other Secured Party is required by law to
          make any payment on account of tax (other than tax on its overall net
          income) or otherwise, on or in relation to any amount received or
          receivable by the Secured Parties hereunder;

     then the sum payable by the Chargor in respect of which such deduction,
     withholding or payment is required to be made shall be increased to the
     extent necessary to ensure that, after the making of such deduction,
     withholding or payment, (and after taking account of any deduction,
     withholding or payment which is required to be made as a result of the
     increase) the Security Trustee receives and retains a net sum equal to the
     sum which it and the other Secured Parties would have received and so
     retained had no such deduction, withholding or payment been made.

1.15 This Guarantee and Debenture is and will remain the property of the
     Security Trustee.
