      Clause 2.2 (Tranche and Bank limits)):

      Notwithstanding any other provision of this Agreement:
      (a)  no Bank shall be obliged to participate in any Utilisation
           under either Tranche, to the extent that if it were to do so the
           aggregate of its participation in the Loans and its Relevant
           Percentage of the Undrawn Face Amount in the Bank Guarantees under
           that Tranche would exceed its Commitment under that Tranche;

   34
                                       33

     not yet occurred) were made, exceed the Tranche A Commitments on the
     proposed Utilisation Date.
(b)  In addition to the obligations under paragraph (a) above, the obligations
     of each Bank to make available or participate in any Tranche A Loan is

           pounds sterling 15,000,000;

           Amount of the Bank Guarantees at that time to exceed the then
           Available Total B Commitments or the aggregate of the Loans and the
           Undrawn Face Amount of the Bank Guarantees to exceed the Total B
           Commitments; and

     demand from the Agent an amount equal to and in the same currency as each
     amount demanded in accordance with paragraph (b) below of, or paid out by,
     the Bank under Clause 7.3 (Payment by the Banks) in respect of any Bank
     Guarantee issued for the account of the Borrower and undertakes to
     indemnify and hold harmless each Finance Party from and against all
     liabilities, costs, losses, damages and expenses which any Finance Party
     may incur or sustain by reason of or arising in any way whatsoever in
     connection with or by reference to the issue of any such Bank Guarantee or
     its performance of the obligations expressed to be assumed by it under any
     such Bank Guarantee save to the extent that any such liability, cost,
     loss, damage or expense:
      (i)   is caused by the wilful misconduct, default or gross negligence of
            the Finance Party concerned; or
      (ii)  represents a day to day cost of the Finance Party incurred by it in
            the ordinary course of its business in connection with or by
            reference to the issue of any Bank Guarantee or the performance of
            the obligations expressed to be assumed by it under or related to
            that Bank Guarantee or in respect thereof which is not an increased
            cost of the nature compensated by the Borrower under Clause 13
            (Taxes) or 15.1 (Increased Costs) or is excluded from costs to be
            compensated under Clauses 13 (Taxes) or 15.1 (Increased Costs) by
            virtue of its express terms.
(b)   The Borrower and each Bank unconditionally and irrevocably:
      (i)   authorises and directs the Issuing Bank to pay any prima facie valid
            demand under and in accordance with any Bank Guarantee issued for
            its account without requiring proof of the agreement of the Borrower
            or any Licence Holding Subsidiary or any Bank that the amounts so
            demanded or paid are or were due and notwithstanding that the
            Borrower or any Licence Holding Subsidiary may dispute the validity
            of any such request, demand or payment;
      (ii)  confirm that the Issuing Bank deals in documents only and shall not
            be concerned with the legality of the claim or any other underlying
            transaction or any set off, counterclaim or defence as between the
            Borrower or any Licence Holding Subsidiary and the Beneficiary of
            any Bank Guarantee; and
      (iii) agree that neither the Issuing Bank nor any Bank need have regard to
            the sufficiency, accuracy or genuineness of any such demand or any
            certificate or statement in
   41
                                       40
            connection therewith or any incapacity of or limitation upon the
            powers of any person signing or issuing such demand, certificate or
            statement which appears on its face to be in order and agree that
            neither the Issuing Bank nor any Bank shall be obliged to enquire
            as to any such matters and may assume that any such demand,
            certificate or statement which appears on its face to be in order
            is correct and properly made.
8.2   RIGHTS OF CONTRIBUTION AND SUBROGATION
(a)   Until the Facility has been fully and irrevocably discharged and all
      amounts which are or may become payable by the Obligors under or in
      connection with the Finance Documents have been irrevocably paid in full,
      no Obligor shall, by virtue of any payment made by it or them under or in
      connection with or referable to this Clause 8 or otherwise, be subrogated
      to any rights, security or moneys held or received by a Finance Party or
      be entitled at any time to exercise, claim or have the benefit of any
      right of contribution or subrogation or similar right against a Finance
      Party.  All rights of contribution or similar rights arising under or in
      connection with the Finance Documents against any Finance Party are hereby
      waived by the Obligors.
(b)   Notwithstanding paragraph (a) above, the Issuing Bank shall, provided that
      no Event of Default is outstanding and provided further that it has been
      satisfactorily indemnified against all potential cost, losses and
      expenses, afford the Obligors such assistance as is reasonably necessary
      in the circumstances to contest any claim made by a Beneficiary which the
      Obligors are able to demonstrate to the reasonable satisfaction of the
      Issuing Bank is a claim that (i) cannot be contested without the
      assistance of the Issuing Bank and (ii) is not properly merited.
8.3   WAIVER OF DEFENCES
      The Borrower agrees that its obligations under this Clause 8 shall not be
      affected by any act, omission, matter or thing which but for this
      provision might operate to release or otherwise exonerate it from its
      obligations hereunder in whole or in part, including without limitation
      and whether or not known to it:
      (a)  any time or waiver granted to or composition with a Finance
           Party, the Beneficiary of any Bank Guarantee or any other person;
      (b)  any taking, variation, compromise, renewal or release of, or
           refusal or neglect to perfect or enforce, any rights, remedies or
           securities available to any Finance Party or other person or arising
           under any Bank Guarantee; or
      (c)  any variation or extension of (where that extension is
           requested by the Borrower) or increase in liabilities under any Bank
           Guarantee, so that references in this Agreement to any Bank
           Guarantee shall include each such extension and variation.
   42
                                       41
8.4   CONTINUING INDEMNITY
      This shall be a continuing indemnity, shall extend to the ultimate balance
      of the obligations and liabilities of the Borrower under this Clause 8 and
      shall continue in force notwithstanding any intermediate payment in whole
      or in part of such obligations or liabilities.
8.5   ADDITIONAL SECURITY
      The obligations of the Borrower under this Clause 8 shall be in addition
      to and shall not be in any way prejudiced by any collateral or other
      security now or hereafter held by any Finance Party as security or any
      lien to which that Finance Party may be entitled.
8.6   PRESERVATION OF RIGHTS
      No invalidity or unenforceability of all or any part of this Clause 8
      shall affect any rights of indemnity or otherwise which any Finance Party
      would or may have in the absence of or in addition to this Clause 8.

     to the Tranche B Term Date 10 days' prior notice if the prepayment is to
     be made before the Tranche B Term Date) to the Agent, prepay (without
     premium but without prejudice to Clause 26.2 (Other indemnities)) any
     Tranche B Loans in whole or in part (but, if in part, in a minimum amount
     of pounds sterling 5,000,000 and an integral multiple of pounds
     sterling 500,000).
(b)  Any Tranche B Loans prepaid prior to the Tranche B Term Date may be
     reborrowed under Tranche B subject to the terms hereof.  Any Tranche B
     Loans prepaid after the Tranche B Term Date may not be reborrowed and
     shall be applied against the Repayment Amounts in inverse order of
     maturity or if so elected by the Borrower by notice in writing prior to
     the date of prepayment, in chronological order of maturity.
9.3  VOLUNTARY CANCELLATION

   43
                                       42
(b)  Any cancellation in part shall be applied against either the relevant
     Tranche A Commitment and/or Tranche B Commitment, as the case may be, of
     each Bank pro rata.
(c)  If, at the same time as cancelling the whole of the Total A Commitments
     and the Total B Commitments, the Borrower repays the Loans, it shall not
     be obliged to satisfy the requirements of paragraphs (a) or (b) above.
9.4  ADDITIONAL RIGHT OF PREPAYMENT AND CANCELLATION
     If:
      (a)  an Obligor is, or will be on the last day of the then current
           interest period, required to pay to a Bank any additional amounts
           under Clause 13 (Taxes) or is otherwise obliged to account for tax
           in respect of interest paid under this Agreement; or
      (b)  an Obligor is or will be required to pay to a Bank any amount
           under Clause 15 (Increased costs and illegality); or
      (c)  interest on a Bank's participation in a Loan is being
           calculated in accordance with Clause 14.4(c)  (Alternative basis),
      then, without prejudice to the obligations of any Obligor under those
      Clauses, the Borrower may, whilst the circumstances continue, serve a
      notice of prepayment and cancellation on that Bank through the Agent.  On
      the date falling 5 Business Days after the date of service of the notice:
      (i)  the Borrower shall prepay that Bank's participation in the
           Loans (without premium but without prejudice to Clause 26.2 (Other
           indemnities));
      (ii) that Bank's Commitment shall be cancelled; and
      (iii) the Borrower shall deposit an amount equal to that Bank's
           Relevant Percentage of all outstanding Bank Guarantees as cash cover
           for the outstanding liabilities of that Bank under those Bank
           Guarantees.
      Any prepayment of a Tranche B Loan under this Clause 9.4 shall be applied
      against the Repayment Amounts in chronological order of maturity.
9.5  MANDATORY PREPAYMENT
(a)  Subject to paragraph (b) below, in relation to any Quarter ending on or
     after the Tranche B Term Date, if the relevant Financial Covenant
     Certificate (as defined in Clause 18.2 (Financial information)) shows
     that:
      (i)  the Total Leverage Ratio for the two previous consecutive
           Quarters for which a Financial Covenant has been received by the
           Agent is less than 4:1; and
      (ii) the amount of Excess Cash Flow for that Quarter is in excess
           of Pounds Sterling 5,000,000 (that excess amount being the "EXCESS
           AMOUNT"),
   44
                                       43
      the Borrower shall prepay the aggregate of the Tranche B Loans up to the
      Excess Amount in an amount equal to the aggregate of:
      (A)  the lesser of Excess High Yield Interest and the Excess
           Amount; and
      (B)  if and to the extent that Excess High Yield Interest is less
           than the Excess Amount, seventy per cent. of the difference between
           those amounts,
      for that Quarter.  Such prepayment shall be made on the first Repayment
      Date following receipt by the Agent of a Financial Covenant Certificate
      relating to such Quarter.  For the purposes of this paragraph (a),
      "EXCESS HIGH YIELD INTEREST" means any amount which is paid in respect of
      cash interest falling due on High Yield Debt due under the Indentures in
      excess of the amount shown in the Agreed Base Case but paid during a
      Quarter in accordance with Clause 18.16(a)(iii) (Distributions).
(b)  Any prepayment under this Clause 9.5 shall be applied against the
     Repayment Amounts in inverse order of maturity as to one half thereof and
     in chronological order of maturity as to the other half thereof.
9.6 MISCELLANEOUS PROVISIONS
(a)  Any notice of prepayment or cancellation under this Clause 9 of this
     Agreement is irrevocable.  The Agent shall notify the Banks promptly of
     receipt of any such notice.
(b)  All prepayments under this Agreement shall be made together with accrued
     interest on the amount prepaid.
(c)  No prepayment or cancellation is permitted except in accordance with the
     express terms of this Agreement.
(d)  No amount of the Total A Commitments or the Total B Commitments cancelled
     under this Agreement may subsequently be reinstated.
(e)  The obligations of each Bank under Clause 7.3 (Payments by the Banks) in
     relation to Bank Guarantees shall continue, notwithstanding any
     cancellation of its Tranche A Commitment or its Tranche B Commitment in
     whole or in part under this Agreement.
10. INTEREST PERIODS
10.1 SELECTION
(a)  The Borrower may select an Interest Period for a Loan in either the
     relevant Loan Request or, if the Loan has been borrowed, a notice received
     by the Agent not later than 2 Business Days before the commencement of
     that Interest Period.  Each Interest Period for a Loan will commence on
     its Drawdown Date or the expiry of its preceding Interest Period.
(b)  Subject to the following provisions of this Clause 10, each Interest
     Period will be for 1, 3 or 6 months or such other duration as the Banks
     may agree, as so selected under paragraph (a) above.
   45
                                       44
(c)   If the Borrower fails to select an Interest Period for an outstanding
      Loan in accordance with paragraph (a) above, that Interest Period will,
      subject to the other provisions of this Clause 10, be 3 months' duration.
10.2  NON-BUSINESS DAYS
      If an Interest Period would otherwise end on a day which is not a
      Business Day, that Interest Period shall instead end on the next Business
      Day in that calendar month (if there is one) or the preceding Business
      Day (if there is not).
10.3  CONSOLIDATION
     
      If the Borrower notifies the Agent with the relevant Request for a Loan
      that it wishes to consolidate that Loan with another Loan of the same
      Tranche, then notwithstanding Clause 10.1 (Selection), the first Interest
      Period for that Loan shall end on the same day as the current Interest
      Period for any other Loan of the same Tranche.  On the last day of those
      Interest Periods, those Loans applicable to each Tranche shall be
      consolidated and treated as one Loan in that Tranche.
10.4  COINCIDENCE WITH REPAYMENT DATES
     
      If an Interest Period would otherwise overrun the Final Maturity Date,
      (or in the case of a Tranche A Loan, the Tranche A Term Date) it shall be
      shortened so that it ends on the Final Maturity Date (or, in the case of
      a Tranche A Loan, the Tranche A Term Date).  The Agent may also shorten
      any Interest Period for any Loan (and may redesignate any Loan as two
      Loans) to ensure that the aggregate principal amount of Loans with an
      Interest Period ending on a Repayment Date is not less than the Repayment
      Amount due on that Repayment Date.
10.5  OTHER ADJUSTMENTS
     
      The Agent and the Borrower may enter into such other arrangements as they
      may agree for the adjustment of Interest Periods and the consolidation or
      splitting of Loans which are outstanding under the same Tranche.
10.6  NOTIFICATION
     
      The Agent shall notify the Borrower and the Banks of the duration of each
      Interest Period promptly after ascertaining its duration.
11.  INTEREST AND GUARANTEE FEE
11.1 INTEREST RATE
(a)  The rate of interest on each Loan for each of its Interest Periods is the
     rate per annum determined by the Agent to be the aggregate of the
     applicable:
      (i)   Margin;
      (ii)  LIBOR; and
      (iii) MLA Cost.
   46
                                       45
(b)  Except as otherwise provided in this Agreement, accrued interest on each
     Loan is payable in arrears by the Borrower on the last day of each
     Interest Period for that Loan and also, if the duration of an Interest
     Period is 6 months or more, on the date falling 6 months after the first
     day of that Interest Period.
11.2 CHANGE OF MARGIN
(a)  In respect of Tranche A Loans, the Margin shall be 2.5 per cent. per
     annum.
(b)  In respect of a Tranche B Loan, the Margin shall be determined on the
     first day of the relevant Interest Period with reference to the Tranche B
     Leverage Ratio as follows:
     (i)   if the Tranche B Leverage Ratio is equal to 3.5 or more, the
           Margin shall be 1.5 per cent. per annum;
     (ii)  if the Tranche B Leverage Ratio is equal to 3.0 or more but
           less than 3.5, the Margin shall be 1 per cent. per annum; and
     (iii) if the Tranche B Leverage Ratio is less than 3.0, the Margin
           shall be 0.75 per cent. per annum.
(c)  For the purposes of paragraph (b) above, the Tranche B Leverage Ratio
     will be the value set out in the most recent Financial Covenant
     Certificate delivered in accordance with Clause 18.2(a)(iii) (Financial
     Information).
(d)  If an Event of  Default has occurred and is continuing at the start of an
     Interest Period, the decrease in Margin will only be effected for that
     Interest Period from the date that such Event of Default ceases to exist.
11.3 GUARANTEE FEE
(a)  The rate of Guarantee Fee applicable to each Bank Guarantee will be the
     same as the rate of the Margin at the time it is payable in accordance
     with paragraph (c) below.
(b)  Guarantee Fee is payable to the Agent for each Bank pro rata to its
     Relevant Percentage under that Bank Guarantee, unless a Bank has received
     cash cover for that Relevant Percentage under Clause 15.3 (Illegality).
(c)  For each Bank Guarantee, Guarantee Fee is payable quarterly in arrears by
     the Borrower from the date of issue of that Bank Guarantee to the expiry
     date of that Bank Guarantee.
11.4 DEFAULT INTEREST
(a)  If an Obligor fails to pay any amount payable by it under the Finance
     Documents, it shall forthwith on demand by the Agent pay interest on the
     overdue amount from the due date up to the date of actual payment, as well
     after as before judgement, at a rate (the "DEFAULT RATE") determined by
     the Agent to be 1 per cent. per annum above the rate which would have been
     payable if the overdue amount had, during the period of non-payment,
     constituted a Loan in the currency of the overdue amount for such
     successive Interest Periods of such duration as the Agent may determine
     (each a "DESIGNATED INTEREST PERIOD").
   47
                                       46
(b)   The default rate will be determined by the Agent on each Business Day or
      the first day of, or two Business Days before the first day of, the
      relevant Designated Interest Period, as appropriate.
(c)   Default interest will be compounded at the end of each Designated
      Interest Period.
11.5  NOTIFICATION
      The Agent shall promptly notify each relevant Party of the determination
      of a rate of interest under this Agreement.
12.   PAYMENTS
12.1  PLACE
      All payments by an Obligor or a Bank under the Finance Documents shall be
      made to the Agent to its account at such office or bank as it may notify
      to that Obligor or Bank for this purpose.
12.2  FUNDS
      Payments under the Finance Documents to the Agent shall be made for value
      on the due date at such times and in such funds as the Agent may specify
      to the Party concerned as being customary at the time for the settlement
      of transactions in Sterling.
12.3  DISTRIBUTION
(a)   Each payment received by the Agent under the Finance Documents for
      another Party shall, subject to paragraphs (b) and (c) below, be made
      available by the Agent to that Party by payment (on the date and in the
      currency and funds of receipt) to its account with such office or bank in
      the principal financial centre of the country of the relevant currency as
      it may notify to the Agent for this purpose by (unless specified in a
      Request or otherwise agreed by the Agent) not less than 5 Business Days'
      prior notice.
(b)   The Agent may apply any amount received by it for an Obligor in or
      towards payment (on the date and in the currency and funds of receipt) of
      any amount due from an Obligor under the Finance Documents.
(c)   Where a sum is to be paid to the Agent under the Finance Documents for
      another Party, the Agent is not obliged to pay that sum to that Party
      until it has established that it has actually received that sum.  The
      Agent may, however, assume that the sum has been paid to it in accordance
      with this Agreement, and, in reliance on that assumption, make available
      to that Party a corresponding amount.  If the sum has not been made
      available but the Agent has paid a corresponding amount to another Party,
      that Party shall forthwith on demand by the Agent refund the corresponding
      amount together with interest on that amount from the date of payment to
      the date of receipt, calculated at a rate determined by the Agent to
      reflect its cost of funds.

      Business Day, the due date for that payment shall instead be the next
      Business Day in the same calendar month (if there is one) or the preceding
      Business Day (if there is not).
(b)   During any extension of the due date for payment of any principal under
      this Agreement interest is payable on that principal at the rate payable
      on the original due date.

      then due and payable by the Obligors under the Finance Documents, the
      Agent shall apply that payment towards the obligations of the Obligors
      under the Finance Documents in the following order:
      (i)   first, in or towards payment pro rata of any unpaid costs and
            expenses of the Agent and the Issuing Bank under the Finance
            Documents;
      (ii)  secondly, in or towards payment pro rata of any unpaid costs

            but unpaid under the Finance Documents.
(b)   The Agent shall, if so directed by all the Banks, vary the order set out
      in sub-paragraphs (a)(ii) to (v) above.
(c)   Paragraphs (a) and (b) above shall override any appropriation made by an
      Obligor.

                                       48
13.    TAXES
13.1   GROSS-UP
       All payments by an Obligor under the Finance Documents shall be made
       without any deduction and free and clear of and without deduction for or
       on account of any taxes, except to the extent that the Obligor is
       required by law to make payment subject to any taxes.  If any UK tax or
       amounts in respect of UK tax must be deducted, or any other deductions
       for or on account of UK tax must be made, from any amounts payable or
       paid by an Obligor, or paid or payable by the Agent to a Finance Party
       under the Finance Documents then, subject to Clause 13.3 (Section 840),
       the Obligor shall pay such additional amounts as may be necessary to
       ensure that the relevant Finance Party receives a net amount equal to
       the full amount which it would have received had payment not been made
       subject to deduction of such tax.
13.2   TAX RECEIPTS
       All taxes required by law to be deducted or withheld by an Obligor from
       any amounts paid or payable under the Finance Documents shall be paid by
       the relevant Obligor when due and the Obligor shall, within 15 days of
       the payment being made, deliver to the Agent for the relevant Bank
       evidence satisfactory to that Bank (including all relevant tax receipts)
       that the payment has been duly remitted to the appropriate authority.
13.3   SECTION 840
       If, otherwise than as a result of the introduction of, change in, or any
       officially published change in the interpretation, administration or
       application of, any law or regulation or any officially published
       practice or concession of the U.K. Inland Revenue occurring after the
       date of this Agreement, a Bank or any New Bank (as defined in Clause 29.2
       (Transfers by Banks)) is not or ceases to be a bank as defined in section
       840A of the Income and Corporation Taxes Act 1988 which is within the
       charge to UK corporation tax with regard to interest to which it is
       entitled under or pursuant to this Agreement (a "QUALIFYING BANK") no
       Obligor will be liable to pay to that Bank or any New Bank (as defined in
       Clause 29.2 (Transfers by Banks)) under Clause 13.1 (Gross-up) any amount
       in respect of taxes levied or imposed by the U.K. or any taxing authority
       of or in the U.K. in excess of the amount it would have been obliged to
       pay if that Bank was or had not ceased to be a Qualifying Bank.
13.4   TAX CREDIT
       If any Bank receives an additional amount by virtue of Clause 13.1
       (Gross-up) and the Bank in question, in its sole opinion (exercised in
       good faith), determines that it has received or been granted a credit
       against or relief or remission for, or repayment of, or other benefit in
       respect of any tax paid or payable by it in respect of, or calculated
       with reference to, the deduction giving rise to such additional amount,
       the Bank in question shall, to the extent that it can do so without
       prejudice to the retention of the amount of relevant credit, relief,
       remission, repayment or other benefit received, pay to the Obligor such
       amount as the Bank shall in its sole opinion (exercised in good faith)
       have concluded to be attributable to the relevant deduction provided
       always that the Bank shall be left in no more or less favourable position
       than it would have been in if no additional amount had been required to
       be paid and the Bank shall be the sole judge of the amount of any such
       benefit and of the date on which it is received, shall have an absolute
       discretion as to the order and manner in which it employs or claims tax
       credits and
   50
                                       49
      allowances available to it and shall not be obliged to disclose to the
      Obligor any information regarding its tax affairs or tax computations.
14.   MARKET DISRUPTION
14.1  ABSENCE OF QUOTATIONS
      If, in circumstances where sub-paragraph (c) of the definition of LIBOR
      applies, the Agent requests a quotation from the Reference Banks and a
      Reference Bank does not supply an offered rate by 12.00 noon on the first
      day of an Interest Period, the applicable LIBOR shall, subject to Clause
      14.2 (Market disruption), be calculated on the basis of the quotations of
      the remaining Reference Banks.
14.2  MARKET DISRUPTION
      If:
      (a)   in circumstances where sub-paragraph (c) of the definition of LIBOR
            applies, the Agent requests a quotation from the Reference Banks and
            no Reference Bank supplies an offered rate by 12.00 noon on the
            first day of an Interest Period for the purposes of calculating
            LIBOR or if no other adequate and fair means exist for ascertaining
            LIBOR; or
      (b)   the Agent receives notification from Banks whose participations in a
            Loan exceed 50 per cent. of that Loan that, in their opinion:
            (i)  matching deposits may not be available to them in
                 the London interbank market in the ordinary course of business
                 to fund their participations in that Loan for the relevant
                 Interest Period; or
            (ii) the cost to them of obtaining matching deposits
                 in the London interbank market would be in excess of LIBOR for
                 the relevant Interest Period,
            the Agent shall promptly notify the Borrower and the Banks of the
            fact and that this Clause 14 is in operation.
14.3  SUSPENSION OF DRAWDOWNS
      If a notification under Clause 14.2 (Market disruption) applies to a Loan
      which has not been made, that Loan shall not be made.  However, within 5
      Business Days of receipt of the notification, the Borrower and the Agent
      shall enter into negotiations for a period of not more than 30 days with
      a view to agreeing an alternative basis for the borrowing of that and any
      future Loan.  Any alternative basis agreed shall be, with the prior
      consent of the Majority Banks, binding on all the Parties.
14.4  ALTERNATIVE BASIS
      If a notification under Clause 14.2 (Market disruption) applies to a Loan
      which is outstanding, then, notwithstanding any other provision of this
      Agreement:
   51
                                       50
      (a)  within 5 Business Days of receipt of the notification, the
           Borrower and the Agent shall enter into negotiations for a period of
           not more than 30 days with a view to agreeing an alternative basis
           for determining the rate of interest and/or funding applicable to
           that Loan and/or any other Loans;
      (b)  any alternative basis agreed under paragraph (a) above shall
           be, with the prior consent of the Majority Banks, binding on all the
           Parties;
      (c)  if no alternative basis is agreed, each Bank shall (through
           the Agent) certify on or before the last day of the Interest Period
           to which the notification relates an alternative basis for
           maintaining its participation in that Loan;
      (d)  any such alternative basis may include an alternative method
           of fixing the interest rate, alternative Interest Periods or
           alternative currencies but it must reflect the cost to the bank of
           funding its participation in the Loan from whatever sources it may
           select plus the Margin plus any applicable MLA Cost; and
      (e)  each alternative basis so certified shall be binding on the
           Obligors and the certifying Bank and treated as part of this
           Agreement.
14.5  MONITORING OF DISRUPTION
      Any notification under Clause 14.2 (Market disruption) shall only apply
      for such period as the relevant market disruption shall continue.
15.   INCREASED COSTS AND ILLEGALITY
15.1  INCREASED COSTS
(a)   Subject to Clause 15.2 (Exceptions), the Borrower shall forthwith on
      demand by a Finance Party pay to that Finance Party the amount of any
      increased cost incurred by it as a result of:
      (i)  any enactment, introduction, variation of, or change in
           (occurring after the date of this Agreement); or
      (ii) any change occurring after the date of this Agreement in the
           commonly accepted interpretation of,

           it having entered into, or performing, maintaining or funding its
           obligations under, any Finance Document; or
      (ii) that portion of an additional cost incurred by a Finance
           Party in making, funding or maintaining all or any advances
           comprised in a class of advances formed by or including its
           participations in the Loans made or issued or to be made or issued
           by it
   52
                                       51
            under this Agreement as is attributable to it making, funding or
            maintaining those participations; or
      (iii) a reduction in any amount payable to a Finance Party or in the
            effective return to a Finance Party under the Finance Documents or a
            reduction in the effective return to a Finance Party on its capital
            as is attributable to the Finance Documents and/or the transactions
            contemplated by the Finance Documents; or
      (iv)  the amount of any payment made by a Finance Party, or the amount of
            any interest or other return foregone by a Finance Party, calculated
            by reference to any amount received or receivable by that Finance
            Party from any other Party under this Agreement,
      and all references in this paragraph (b) to a Finance Party shall be
      deemed to include its Holding Company.
15.2  EXCEPTIONS
     
      Clause 15.1 (Increased costs) does not apply to any increased cost:
      (a)  compensated for by the payment of the MLA Cost;
      (b)  compensated for by the operation of Clause 13 (Taxes) or
           which would have been compensated therefor but for the operation of
           the exceptions to that Clause; or
      (c)  attributable to any change in the rate of Tax on the overall
           net income of a Bank (or the overall net income of a division or
           branch of the Bank) imposed in the jurisdiction in which its
           principal office or Facility Office is situate or in which such Bank
           transacts business.
15.3  ILLEGALITY
      If it is or becomes unlawful in any jurisdiction for a Bank to give
      effect to any of its obligations as contemplated by this Agreement or to
      fund or maintain its participation in any Loan or to participate in a
      Bank Guarantee, then:
      (a)  that Bank may notify the Borrower in writing through the
           Agent accordingly; and
      (b)  within 10 days following the date of the notification under
           paragraph (a) above (or such earlier date as may be necessary to
           avoid the unlawfulness) and only to the extent necessary to cure the
           unlawfulness:
           (i)   the Borrower shall prepay that Bank's
                 participation in the Loans (without premium but without
                 prejudice to Clause 26.2 (Other indemnities));
           (ii)  the Agent may, by notice to the Borrower declare
                 that, if any Bank Guarantee has not been issued, it shall not
                 be issued;
           (iii) the Agent may, by notice to the Borrower if any
                 Bank Guarantee has been issued, demand that the relevant
                 Borrower shall within five Business Days (or, if later,  the
                 latest date permitted by the relevant law) provide cash cover
   53
                                       52
                  to the affected Bank in an amount equal to that Bank's maximum
                  aggregate actual and contingent liability under that Bank
                  Guarantee and use its reasonable endeavours to procure the
                  release of the Bank from its obligations under the Finance
                  Documents in respect of that Bank Guarantee; and
            (iv)  that Bank's Tranche A Commitment and Tranche B Commitment 
                  shall be cancelled.
15.4  MITIGATION
      If a Bank becomes aware of circumstances that will lead to that Bank
      serving a notice under Clause 15.3 (Illegality) or additional amounts
      becoming payable under Clauses 15.1 (Increased costs) or 13.1 (Gross up),
      that Bank shall, without prejudice to the obligations of the Borrower,
      take such steps as are reasonably open to it (but at no cost itself) to
      mitigate the effect of those circumstances.
16.   GUARANTEE
16.1  GUARANTEE
      Each Obligor irrevocably, unconditionally, jointly and severally:
      (a)  as principal obligor, guarantees to each Finance Party prompt
           performance by each other Obligor of all such other Obligor's
           obligations under the Finance Documents;
      (b)  undertakes with each Finance Party that it shall forthwith on
           demand by the Agent whenever any other Obligor does not pay any
           amount when due under or in connection with any Finance Document,
           pay that amount as if it instead of the other Obligor were expressed
           to be the principal obligor; and
      (c)  indemnifies each Finance Party on demand against any loss or
           liability suffered by such Finance Party it if any obligation
           guaranteed by any Obligor under this Clause 16.1 is or becomes
           unenforceable, invalid or illegal.
16.2  CONTINUING GUARANTEE
      This guarantee is a continuing guarantee and will extend to the ultimate
      balance of all sums payable by any Obligor under the Finance Documents,
      regardless of any intermediate payment or discharge in whole or in part.
16.3  REINSTATEMENT
(a)   Where any discharge (whether in respect of the obligations of any Obligor
      or any security for those obligations or otherwise) is made in whole or in
      part or any arrangement is made on the faith of any payment, security or
      other disposition which is avoided or must be restored on insolvency,
      liquidation or otherwise without limitation, the liability of each Obligor
      under this Clause 16 shall continue as if the discharge or arrangement had
      not occurred.
(b)   Each Finance Party may concede or compromise any claim that any payment,
      security or other disposition is liable to avoidance or restoration.

16.4  WAIVER OF DEFENCES
      The obligations of each Obligor under this Clause 16 will not be affected
      by any act, omission, matter or thing which, but for this provision,
      would reduce, release or prejudice any of its obligations under this
      Clause 16 or prejudice or diminish those obligations in whole or in part,
      including (whether or not known to it or any Finance Party):
      (a)  any time or waiver granted to, or composition with, any
           Obligor or other person;
      (b)  the taking, variation, compromise, exchange, renewal or
           release of, or refusal or neglect to perfect, take up or enforce,
           any rights against, or security over assets of, any Obligor or other
           person or any non-presentation or non-observance of any formality or
           other requirement in respect of any instrument or any failure to
           realise the full value of any security;
      (c)  any incapacity or lack of powers, authority or legal
           personality of or dissolution or change in the members or status of
           any Obligor or any other person;
      (d)  any variation (however fundamental) or replacement of a
           Finance Document or any other document or security so that
           references to that Finance Document in this Clause 16 shall include
           each variation or replacement;
      (e)  any unenforceability, illegality or invalidity of any
           obligation of any person under any Finance Document or the other
           document or security, to the intent that each Obligor's obligations
           under this Clause 16 shall remain in full force and its guarantee be
           construed accordingly, as if there were no unenforceability,
           illegality or invalidity;
      (f)  any postponement, discharge, reduction, non-provability or
           other similar circumstance affecting any obligation of any Obligor
           under a Finance Document resulting from any insolvency, liquidation
           or dissolution proceedings or from any law, regulation or order so
           that each such obligation shall for the purposes of the Obligor's
           obligations under this Clause 16 shall be construed as if there were
           no such circumstance.
16.5  IMMEDIATE RECOURSE
      Each Obligor waives any right it may have of first requiring any Finance
      Party (or any trustee or agent on its behalf) to proceed against or
      enforce any other rights or security or claim payment from any other
      Obligor or other person before claiming from such Obligor under this
      Clause 16.
16.6  APPROPRIATIONS

      (a)  refrain from applying or enforcing any other moneys, security
           or rights held or received by that Finance Party (or any trustee or
           agent on its behalf) in respect of those amounts, or apply and
           enforce the same in such manner and order as it sees fit (whether
           against those amounts or otherwise) and no Obligor shall be entitled
           to the benefit of the same; and
   55
                                       54
      (b)  hold in a suspense account (subject to the accrual of
           interest thereon at available market rates for the account of the
           relevant Obligor) any moneys received from any Obligor or on account
           of any Obligor's liability under this Clause 16.
16.7  NON-COMPETITION
      Until all amounts which may be or become payable by the Obligors under or
      in connection with the Finance Documents have been irrevocably paid in
      full, no Obligor shall, after a claim has been made or by virtue of any
      payment or performance by it under this Clause 16:
      (a)  be subrogated to any rights, security or moneys held,
           received or receivable by any Finance Party (or any trustee or agent
           on its behalf) or be entitled to any right of contribution or
           indemnity in respect of any payment made or moneys received on
           account of that Obligor's liability under this Clause 16;
      (b)  claim, rank, prove or vote as a creditor of any Obligor or
           its estate in competition with any Finance Party (or any trustee or
           agent on its behalf); or
      (c)  receive, claim or have the benefit of any payment,
           distribution or security from or on account of any Obligor, or
           exercise any right of set-off as against any Obligor.
      Each Obligor shall hold in trust for and forthwith pay or transfer to the
      Agent for the Finance Parties any payment or distribution or benefit of
      security received by it contrary to this Clause 16.7.

                  be required to be made to this Agreement to place the Banks in
                  the same position they would have been in if the change had
                  not taken place; the auditor's certificate will, in the
                  absence of manifest error, be binding on all the Parties.

      (e)  instruct the Agent to enforce all or part of the security
           constituted under or pursuant to the Security Documents or enforce
           any other right held by it.
22.   THE AGENT, THE SECURITY AGENT AND THE ARRANGERS
22.1  APPOINTMENT AND DUTIES OF THE AGENT
      Each Finance Party (other than the Agent) irrevocably appoints the Agent
      and each Finance Party (other than the Security Agent) irrevocably
      appoints the Security Agent to act as its agent
   83
                                       82
      on its behalf, in each case under and in connection with the Finance
      Documents, and irrevocably authorises the Agent and/or, as the case may
      be, the Security Agent on its behalf to perform the duties and to exercise
      the rights, powers and discretions that are specifically delegated to it
      under or in connection with the Finance Documents, together with any other
      incidental rights, powers and discretions.  The Agent and the Security
      Agent each have only those duties which are expressly specified in the
      Finance Documents, and those duties are solely of a mechanical and
      administrative nature.
22.2  ROLE OF THE ARRANGERS
      Except as specifically provided in the Finance Documents, the Arrangers
      have no obligations of any kind to any other Party under or in connection
      with any Finance Document.
22.3  RELATIONSHIP
      The relationship between the Agent and the other Finance Parties is that
      of agent and principal only.  Except as contemplated by the Security
      Documents, nothing in this Agreement constitutes the Agent as trustee or
      fiduciary for any other Party or any other person and the Agent need not
      hold in trust any moneys paid to it for a Party or be liable to account
      for interest on those moneys.
22.4  MAJORITY BANKS' DIRECTIONS
      Each of the Agent and the Security Agent will be fully protected if it
      acts in accordance with the instructions of the Majority Banks in
      connection with the exercise of any right, power or discretion or any
      matter not expressly provided for in the Finance Documents.  The Agent
      or, as the case may be, the Security Agent will promptly notify the Banks
      of any instructions given by the Majority Banks.  Any such instructions
      given by the Majority Banks will be binding on all the Banks.  In the
      absence of such instructions, each of the Agent and the Security Agent
      may act as it considers to be in the best interests of all the Banks.
22.5  DELEGATION
      The Agent and the Security Agent may act under the Finance Documents
      through their respective personnel and agents.
22.6  RESPONSIBILITY FOR DOCUMENTATION
      None of the Agent, the Security Agent nor any Arranger is responsible to
      any other Party for:
      (a)  the execution, genuineness, validity, enforceability or
           sufficiency of any Finance Document or any other document;
      (b)  the collectability of amounts payable under any Finance
           Document; or
      (c)  the accuracy of any statements (whether written or oral) made
           in or in connection with any Finance Document (including the
           Information Memorandum).
   84
                                       83
22.7  DEFAULT
(a)   Neither the Agent nor the Security Agent is obliged to monitor or enquire
      as to whether or not a Default has occurred.  Neither the Agent nor the
      Security Agent will be deemed to have knowledge of the occurrence of a
      Default.  However, if the Agent or the Security Agent receives notice from
      a Party referring to this Agreement, describing the Default and stating
      that the event is a Default, it shall promptly notify the Banks.
(b)   Each of the Agent and the Security Agent may require from the Banks the
      receipt of security satisfactory to it, whether by way of payment in
      advance or otherwise, against any liability or loss which it will or may
      incur in taking any proceedings or action arising out of or in connection
      with any Finance Document before it commences those proceedings or takes
      that action.
22.8 EXONERATION
(a)   Without limiting paragraph (b) below, neither the Agent nor the Security
      Agent will be liable to any other Party for any action taken or not taken
      by it under or in connection with any Finance Document, unless directly
      caused by its gross negligence or wilful misconduct.
(b)   No Party may take any proceedings against any officer, employee or agent
      of the Agent in respect of any claim it might have against the Agent or
      the Security Agent or in respect of any act or omission of any kind
      (including gross negligence or wilful misconduct) by that officer,
      employee or agent in relation to any Finance Document.
22.9  RELIANCE
      Each of the Agent and the Security Agent may:
      (a)  rely on any notice or document believed by it to be genuine
           and correct and to have been signed by, or with the authority of,
           the proper person;
      (b)  rely on any statement made by a director or employee of any
           person regarding any matters which may reasonably be assumed to be
           within their knowledge or within their power to verify; and
      (c)  engage, pay for and rely on legal or other professional
           advisers selected by it (including those in the Agent's or the
           Security Agent's employment and those representing a Party other
           than the Agent or the Security Agent).
22.10 CREDIT APPROVAL AND APPRAISAL
      Without affecting the responsibility of any Obligor for information
      supplied by it or on its behalf in connection with any Finance Document,
      each Bank confirms that it:
      (a)   has made its own independent investigation and assessment of the
            financial condition and affairs of each Obligor and its related
            entities in connection with its participation in this Agreement and
            has not relied exclusively on any information provided to it by the
            Agent or the Arrangers in connection with any Finance Document; and
   85
                                       84
      (b)   will continue to make its own independent appraisal of the
            creditworthiness of each Obligor and its related entities while any
            amount is or may be outstanding under the Finance Documents or any
            Commitment is in force.
22.11 INFORMATION
(a)   The Agent shall promptly forward to the person concerned the original or a
      copy of any document which is delivered to the Agent by a Party for that
      person.
(b)   The Agent shall promptly supply a Bank with a copy of each document
      received by the Agent under Clause 4 (Conditions Precedent) upon the
      request and at the expense of that Bank.
(c)   Except where this Agreement specifically provides otherwise, neither the
      Agent nor the Security Agent is obliged to review or check the accuracy or
      completeness of any document it forwards to another Party.
(d)   Except as provided above, neither the Agent nor the Security Agent has any
      duty:
      (i)  either initially or on a continuing basis to provide any Bank
           with any credit or other information concerning the financial
           condition or affairs of any Obligor or any related entity of any
           Obligor whether coming into its possession before, on or after the
           date of this Agreement; or
      (ii) unless specifically requested to do so by a Bank in
           accordance with this Agreement, to request any certificates or other
           documents from any Obligor.
22.12 THE AGENT, THE SECURITY AGENT AND THE ARRANGERS INDIVIDUALLY
(a)   If it is also a Bank, each of the Agent, the Security Agent and an
      Arranger has the same rights and powers under this Agreement as any other
      Bank and may exercise those rights and powers as though it were not the
      Agent, the Security Agent or an Arranger.
(b)   If it is also a Bank, any reference in the Finance Documents to the Agent
      means the agency department of the Agent specifically responsible for
      acting as Agent under and in connection with the Finance Documents, as
      referred to in Clause 35 (Notices).  In acting as Agent, the agency
      department will be treated as a separate entity from any other department
      or division of the Bank concerned.  Without limiting the above, the Agent
      will not be deemed to have notice of a document, information, fact, matter
      or thing in the possession or knowledge of any other department or
      division of that Bank.
(c)   Each of the Agent, the Security Agent and each Arranger may:
      (i)  carry on any business with an Obligor or its related
           entities;
      (ii) act as agent or trustee for, or in relation to any financing
           involving, an Obligor or its related entities; and
      (iii) retain any profits or remuneration in connection with its
           activities under this Agreement or in relation to any of the
           foregoing.
   86
                                       85
22.13 INDEMNITIES
(a)   Without limiting the liability of any Obligor under the Finance Documents,
      each Bank shall forthwith on demand indemnify the Agent and the Security
      Agent for its proportion of any liability or loss incurred by the Agent
      or, as the case may be, the Security Agent in any way relating to or
      arising out of its acting as the Agent or Security Agent, except to the
      extent that the liability or loss arises directly from the Agent's or the
      Security Agent's gross negligence or wilful misconduct.
(b)   A Bank's proportion of the liability set out in paragraph (a) above will
      be the proportion which its participation in the Utilisations (if any)
      bear to all the Utilisations on the date of the demand.  If, however,
      there are no Utilisations outstanding on the date of demand, then the
      proportion will be the proportion which its Tranche B Commitment bears to
      the Total B Commitments at the date of demand or, if the Total B
      Commitments have then been cancelled, bore to the Total B Commitments
      immediately before being cancelled.
(c)   The Borrower shall forthwith on demand reimburse each Bank for any payment
      made by it under paragraph (a) above.
22.14 COMPLIANCE
(a)   Each of the Agent and the Security Agent may refrain from doing anything
      which might, in its opinion, constitute a breach of any law or regulation
      or be otherwise actionable at the suit of any person, and may do anything
      which, in its opinion, is necessary or desirable to comply with any law or
      regulation of any jurisdiction.
(b)   Without limiting paragraph (a) above, neither the Agent nor the Security
      Agent need disclose any information relating to any Obligor or any of its
      related entities if the disclosure might, in the opinion of the Agent or,
      as the case may be, the Security Agent, constitute a breach of any law or
      regulation or any duty of secrecy or confidentiality or be otherwise
      actionable at the suit of any person.
22.15 RESIGNATION OF THE AGENT
(a)   Notwithstanding its irrevocable appointment, the Agent may (and, if the
      Majority Banks so request, shall) resign by giving notice to the Banks and
      the Borrower.  The Agent will not give such notice without the consent of
      the Borrower (such consent not to be unreasonably withheld).  On giving
      such notice, the Agent may forthwith appoint one of its Affiliates as
      successor Agent or, failing that, the Majority Banks, following
      consultation with the Borrower, may appoint a successor Agent.
(b)   If the appointment of a successor Agent is to be made by the Majority
      Banks but they have not, within 30 days after notice of resignation,
      appointed a successor Agent which accepts the appointment, the Agent,
      following consultation with the Borrower, may appoint a successor Agent.
(c)   The resignation of the Agent and the appointment of any successor Agent
      will both become effective only upon the successor Agent notifying all the
      Parties that it accepts its appointment.  On giving the notification, the
      successor Agent will succeed to the position of the Agent and the term
      "AGENT" will mean the successor Agent.
   87
                                       86
(d)   The retiring Agent shall, at its own cost, make available to the
      successor Agent such documents and records and provide such assistance as
      the successor Agent may reasonably request for the purposes of performing
      its functions as the Agent under this Agreement.
(e)   Upon its resignation becoming effective, this Clause 22 shall continue to
      benefit the retiring Agent in respect of any action taken or not taken by
      it under or in connection with the Finance Documents while it was the
      Agent, and, subject to paragraph (d) above, it shall have no further
      obligations under any Finance Document.
22.16 BANKS
      Each of the Agent and the Security Agent may treat each Bank as a Bank,
      entitled to payments under this Agreement and as acting through its
      Facility Office(s) until it has received notice from that Bank to the
      contrary not less than (unless otherwise agreed by the Agent or, as the
      case may be, the Security Agent) 5 Business Days' prior to the relevant
      payment.
22.17 SECURITY AGENT AS TRUSTEE
      The Security Agent in its capacity as trustee or otherwise under the
      Security Documents:
      (a)  is not liable for any failure, omission or defect in perfecting or
           registering the security constituted or created by any Security
           Document;
      (b)  may accept without enquiry such title as any Obligor may have
           to any asset secured by any Security Document; and
      (c)  is not under any obligation to hold any Security Document or
           any other document in connection with the Security Documents or the
           assets secured by any Security Document (including title deeds) in
           its own possession or to take any steps to protect or preserve the
           same.  The Security Agent may permit any Obligor to retain any
           Security  Document or other document in its possession.

      The Borrower shall pay to the Agent for the Arrangers an arrangement fee

            obligation against any loss or liability arising out of or as a
            result of the conversion;
      (ii)  if the amount received by that Finance Party, when converted into
            the contractual currency at a market rate in the usual course of its
            business is less than the amount owed in the contractual currency,
            the Obligor concerned shall forthwith on demand pay to that Finance
            Party an amount in the contractual currency equal to the deficit;
            and

      (e)  any claim relating to environmental matters or any actual or
           alleged breach of or failure to comply with any Environmental Law or

           incurred by that Finance Party would not have arisen if this
           Agreement or any of the other Finance Documents had not been
           executed.
      Each Obligor's liability in each case includes any loss of margin and

      Finance Parties, an amendment or waiver to which they or the Majority
      Banks have agreed.
(b)   The Agent shall promptly notify the other Parties of any amendment or
      waiver effected under paragraph (a) above, and any such amendment or
      waiver shall be binding on all the Parties.
28.2  EXCEPTIONS
      Subject to Clause 28.3 (Additional High Yield Debt), an amendment or
      waiver not agreed by a Bank and which relates to:
      (a)  the definition of "MAJORITY BANKS" in Clause 1.1;
      (b)  an extension of the date for, or a decrease in an amount or a
           change in the currency of, any payment to or by that Bank under any

           Obligors otherwise than in accordance with Clause 29.4 (Additional
           Obligors);
      (e)  a term of a Finance Document which expressly requires the
           consent of each Bank;

      (g)  any release of any security constituted by a Security
           Document other than in connection with a disposal of an asset by an
           Obligor which is permitted by the terms of this Agreement,
      is not binding on that Bank.
28.3  ADDITIONAL HIGH YIELD DEBT
      If Additional High Yield Debt is raised and is injected in to the
      Borrower Group as Aggregate Cash Equity which has been spent on
      Qualifying Expenditure, then:
      (a)  the Borrower shall notify the Agent of the amount of that
           Additional High Yield Debt;
      (b)  the Borrower and the Agent (acting reasonably and in good
           faith) shall enter into negotiations for a period of not less than
           30 days with a view to agreeing the amendments to this Agreement
           required to reflect the injection of that Aggregate Cash Equity;
      (c)  the amendments in paragraph (b) above shall:
            (i)   for Clause 6.2 (Repayment of Tranche B) reflect the revised
                  cash flow profile;
   92
                                       91
            (ii)  include a reduction on the amount of the Total B Commitments
                  (on a pro rata basis for the Banks) by an amount at least
                  equal to the amount of that Additional Aggregate Cash Equity
                  (which for the avoidance of doubt would reduce the amount of
                  the Total B Commitments on which commitment fee is payable
                  under Clause 23.2 (Commitment fee)); and
            (iii) adjust the covenant levels in Clause 18.24 (Financial
                  covenants) (other than under sub-paragraph (b)(iv) of that

            (iv) adjust the amount of the dividend or distribution permitted
                  under Clause 18.16(a) (Restrictions) to fund cash interest
                  falling due on High Yield Debt issued under the Indentures,
                  together with the related adjustment relating to Excess High
                  Yield Interest under Clause 9.5 (Mandatory prepayment), in
                  each case to reflect the impact of the Additional Aggregate
                  Cash Equity on the Agreed Base Case, such adjustment to be
                  calculated in a manner consistent with the methodology used in
                  calculating the Agreed Base Case; and
            (v)  if as a result of the injection of the Additional
                 Aggregate Cash Equity the first projected borrowings under
                 Tranche B are after 31st March, 1998, Clause 4.3(b) will
                 provide, in respect of a first drawdown under Tranche B prior
                 to 1st April, 1998, that the Reported Annualised Cash Flow is
                 an amount of not less than Pounds Sterling18,500,000;
      (d)   any agreement between the Borrower and the Agent under paragraph (b)
            above shall, with the prior consent of all the Banks, be binding on
            all the Parties;
      (e)   if no agreement is reached under paragraph (b) above, the Agent
            shall certify the amendments that would need to be made to this
            Agreement which would leave the Banks and the Obligors in no better
            or worse position than under this Agreement after taking into
            account the injection of the  Additional Cash Equity; and
      (f)   a certificate of the Agent under paragraph (e) above shall, in the
            absence of manifest error in calculations, be binding on all the
            Parties.
28.4  WAIVERS AND REMEDIES CUMULATIVE
    
      The rights of each Finance Party under the Finance Documents:
      (a)  may be exercised as often as necessary;
      (b)  are cumulative and not exclusive of its rights under the
           general law; and
      (c)  may be waived only in writing and specifically.
      Delay in exercising or non-exercise of any such right is not a waiver of
      that right.
   93
                                       92
29.   CHANGES TO THE PARTIES
29.1  TRANSFERS BY OBLIGORS
      No Obligor may assign, transfer, novate or dispose of any of, or any
      interest in, its rights and/or obligations under the Finance Documents.
29.2  TRANSFERS BY BANKS
(a)   A Bank (the "EXISTING BANK") may at any time assign, transfer or novate
      any part of its Commitment and/or any of its rights and/or obligations
      under this Agreement to another bank or financial institution (the "NEW
      BANK"). The prior consent of the Borrower is required (such consent not to
      be unreasonably withheld or delayed) for any such assignment, transfer or
      novation, unless:
      (i)   the New Bank is an Affiliate of a Bank (and for these purposes,
            ▇▇▇▇▇▇▇ ▇▇▇▇▇ International Bank shall be treated as an Affiliate of
            GS Credit Partners L.P.); or
      (ii)  an Event of Default is outstanding.
(b)   A transfer of obligations will be effective only if either:
      (i)   the obligations are novated in accordance with Clause 29.3
            (Procedure for novations); or
      (ii)  the New Bank confirms to the Agent and each Obligor that it
            undertakes to be bound by the terms of this Agreement as a Bank in
            form and substance satisfactory to the Agent.  On the transfer
            becoming effective in this manner the Existing Bank shall be
            relieved of its obligations under this Agreement to the extent that
            they are transferred to the New Bank,
      and in either case, the obligations of the Existing Bank under the other
      Finance Documents (including, without limitation, a Co-ordination
      Agreement) (or, in the case of a transfer of a proportion of the Existing
      Bank's obligations under this Agreement, the relevant proportion of such
      other obligations) are transferred in accordance with any relevant
      provisions of those Finance Documents.
(c)   Nothing in this Agreement restricts the ability of a Bank to sub-contract
      an obligation if that Bank remains liable under this Agreement for that
      obligation.
(d)   On each occasion an Existing Bank assigns, transfers or novates any of its
      rights and/or obligations under this Agreement, the New Bank shall, on the
      date the assignment, transfer and/or novation takes effect, pay to the
      Agent for its own account a fee of pounds sterling 750.
(e)   An Existing Bank is not responsible to a New Bank for:
      (i)   the execution, genuineness, validity, enforceability or sufficiency
            of any Finance Document or any other document;
      (ii)  the collectability of amounts payable under any Finance Document; or
   94
                                       93
      (iii) the accuracy of any statements (whether written or oral) made in or
            in connection with any Finance Document.
(f)   Each New Bank confirms to the Existing Bank and the other Finance Parties
      that it:
      (i)   has made its own independent investigation and assessment of the
            financial condition and affairs of each Obligor and its related
            entities in connection with its participation in this Agreement and
            has not relied exclusively on any information provided to it by the
            Existing Bank in connection with any Finance Document; and
      (ii)  will continue to make its own independent appraisal of the
            creditworthiness of each Obligor and its related entities while any
            amount is or may be outstanding under this Agreement or any
            Commitment is in force.
(g)   Nothing in any Finance Document obliges an Existing Bank to:
      (i)   accept a re-transfer from a New Bank of any of the rights and/or
            obligations assigned, transferred or novated under this Clause; or
      (ii)  support any losses incurred by the New Bank by reason of the
            non-performance by any Obligor of its obligations under the Finance
            Documents or otherwise.
(h)   Any reference in this Agreement to a Bank includes a New Bank but excludes
      a Bank if no amount is or may be owed to or by it under this Agreement and
      its Commitment has been cancelled or reduced to nil.
(i)   If at any time a Bank assigns, transfers or novates any of its rights or
      obligations under this Agreement to any person (a "SUCCESSOR") and as a
      result, an Obligor is obliged to make a payment under this Agreement for
      the account of such Successor at the time any other payment is due under
      this Agreement and the amount of such payment is in excess of the amount
      which such Obligor would have been obliged to pay for the account of such
      Successor if no such assignment, transfer or novation had occurred, then
      such Obligor shall not be required to pay such excess.
29.3  PROCEDURE FOR NOVATIONS
(a)   A novation is effected if:
      (i)   the Existing Bank and the New Bank deliver to the Agent a duly
            completed certificate, substantially in the form of Part 1 of
            Schedule 6 (a "NOVATION CERTIFICATE") and such delivery may be by
            fax and such faxed copy may be duly executed by the Agent; and
      (ii)  the Agent executes it (which the Agent shall promptly do).
(b)   Each Party (other than the Existing Bank and the New Bank) irrevocably
      authorises the Agent to execute any duly completed Novation Certificate on
      its behalf.
(c)   To the extent that they are expressed to be the subject of the novation in
      the Novation Certificate:
   95
                                       94
      (i)   the Existing Bank and the other Parties (the "EXISTING PARTIES")
            will be released from their obligations to each other (the
            "DISCHARGED OBLIGATIONS");
      (ii)  the New Bank and the existing Parties will assume obligations
            towards each other which differ from the discharged obligations only
            insofar as they are owed to or assumed by the New Bank instead of
            the Existing Bank;
      (iii) the rights of the Existing Bank against the existing Parties and
            vice versa (the "DISCHARGED RIGHTS") will be cancelled; and
      (iv)  the New Bank and the existing Parties will acquire rights against
            each other which differ from the discharged rights only insofar as
            they are exercisable by or against the New Bank instead of the
            Existing Bank,
      all on the date of execution of the Novation Certificate by the Agent or,
      if later, the date specified in the Novation Certificate.
29.4 ADDITIONAL OBLIGORS
(a)   The Borrower shall procure that within 14 days of any company becoming a
      Subsidiary after the date of this Agreement that company becomes an
      Additional Obligor by delivery to the Agent of an Obligor Accession
      Agreement, duly executed by that Subsidiary.
(b)   Upon execution and delivery of an Obligor Accession Agreement, the
      relevant Subsidiary will become an Additional Obligor.
(c)   The Borrower shall procure that, at the same time as an Obligor Accession
      Agreement is delivered to the Agent, there is also delivered to the Agent
      all those other documents listed in Part 3 of Schedule 3, in each case in
      form and substance satisfactory to the Agent.
(d)   The execution of an Obligor Accession Agreement constitutes confirmation
      by the Subsidiary that the representations and warranties set out in
      Clause 17 (Representations and warranties) to be made by it on the date of
      the Obligor Accession Agreement are correct, as if made with reference to
      the facts and circumstances then existing.
29.5  REFERENCE BANKS
      If a Reference Bank (or, if a Reference Bank is not a Bank, the Bank of
      which it is an Affiliate) ceases to be a Bank, the Agent shall (in
      consultation with the Borrower) appoint another Bank or an Affiliate of a
      Bank to replace that Reference Bank.
29.6  REGISTER
      The Agent shall keep a register of all the Parties and shall supply any
      other Party (at that Party's expense) with a copy of the register on
      request.
30.   DISCLOSURE OF INFORMATION
(a)   Subject to paragraph (b) below, a Finance Party may disclose to one of its
      Affiliates or any person (a "PROSPECTIVE TRANSFEREE") with whom it is
      proposing to enter, or has entered into, any kind of transfer,
      participation or other agreement in relation to this Agreement:
   96
                                       95
      (i)   a copy of any Finance Document; and
      (ii)  any information which that Finance Party has acquired under or in
            connection with any Finance Document,
      other than any information which the Borrower specifically designates as
      confidential, the disclosure of which shall be subject to that Finance
      Party procuring the entry into appropriate confidentiality arrangements by
      anyone in receipt thereof.
(b)   An Arranger shall only distribute such information to a prospective
      transferee for the purposes of syndication as contemplated by Clause 18.28
      (Syndication) as the Borrower has authorised in writing for distribution.
31.   SET-OFF
      A Finance Party may set off any matured obligation owed by an Obligor
      under the Finance Documents (to the extent beneficially owned by that
      Finance Party) against any obligation (whether or not matured) owed by
      that Finance Party to that Obligor, regardless of the place of payment,
      booking branch or currency of either obligation.  If the obligations are
      in different currencies, the Finance Party may convert either obligation
      at a market rate of exchange in its usual course of business for the
      purpose of the set-off.  If either obligation is unliquidated or
      unascertained, the Finance Party may set off in an amount estimated by it
      in good faith to be the amount of that obligation.
32.   PRO RATA SHARING
32.1  REDISTRIBUTION
      If any amount owing by an Obligor under the Finance Documents to a
      Finance Party is discharged by payment, set-off or any other manner other
      than through the Agent in accordance with Clause 12 (Payments) (a
      "RECOVERY"), then:
      (a)  the relevant Finance Party (the "RECOVERING FINANCE PARTY")
           shall, within 3 Business Days, notify details of the recovery to the
           Agent;
      (b)  the Agent shall determine whether the recovery is in excess
           of the amount which the recovering Finance Party would have received
           had the recovery been received by the Agent and distributed in
           accordance with Clause 12 (Payments);
      (c)  subject to Clause 32.3 (Exception), the recovering Finance
           Party shall within 3 Business Days of demand by the Agent pay to the
           Agent an amount (the "REDISTRIBUTION") equal to the excess;
      (d)  the Agent shall treat the redistribution as if it were a
           payment by the Obligor concerned under Clause 12 (Payments) and
           shall pay the redistribution to the Finance Parties (other than the
           recovering Finance Party) in accordance with Clause 12.7 (Partial
           payments); and
      (e)  after payment of the full redistribution, the recovering
           Finance Party will be subrogated to the portion of the claims paid
           under paragraph (d) above and that
   97
                                       96
            Obligor will owe the recovering Finance Party a debt which is equal
            to the redistribution, immediately payable and of the type
            originally discharged.
32.2  REVERSAL OF REDISTRIBUTION
  
      If under Clause 32.1 (Redistribution):
      (a)   a recovering Finance Party must subsequently return a recovery, or
            an amount measured by reference to a recovery, to an Obligor; and
      (b)   the recovering Finance Party has paid a redistribution in relation
            to that recovery, each Finance Party shall, within 3 Business Days
            of demand by the recovering Finance Party through the Agent,
            reimburse the recovering Finance Party all or the appropriate
            portion of the redistribution paid to that Finance Party. Thereupon,
            the subrogation in Clause 32.1(e) will operate in reverse to the
            extent of the reimbursement.
32.3  EXCEPTION
      A recovering Finance Party need not pay a redistribution to the extent
      that it would not, after the payment, have a valid claim against the
      Obligor concerned in the amount of the redistribution pursuant to Clause
      32.1(e). 
33.   SEVERABILITY
      If a provision of any Finance Document is or becomes illegal, invalid or
      unenforceable in any jurisdiction, that shall not affect:
      (a)  the validity or enforceability in that jurisdiction of any
           other provision of the Finance Documents; or
      (b)  the validity or enforceability in other jurisdictions of that
           or any other provision of the Finance Documents.
34.   COUNTERPARTS
      Each Finance Document may be executed in any number of counterparts, and
      this has the same effect as if the signatures on the counterparts were on
      a single copy of the Finance Document.

              BY + L(Y - X) + S(Y - Z) % per annum MLA Cost
              ------------------------
                    100 - (B + S)
      where on the day of application of the formula:
      B    is the percentage of the Agent's eligible liabilities which
           the Bank of England requires the Agent to hold on a
           non-interest-bearing deposit account in accordance with its cash
           ratio requirements;
      Y    is the rate at which Sterling deposits are offered by the
           Agent to leading banks in the London interbank market at or about
           11.00 a.m. on that day for the relevant period;
      L    is 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;
      X    is the rate at which secured Sterling deposits may be placed
           by the Agent with members of the London Discount Market Association
           at or about 11.00 a.m. on that day for the relevant period or, if
           greater, the rate at which Sterling bills of exchange (of a tenor
           equal to the duration of 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    is the percentage of the Agent's eligible liabilities which
           the Bank of England requires the Agent to place as a special
           deposit; and
      Z    is the interest rate per annum allowed by the Bank of England
           on special deposits.
(b)  For purposes of this Schedule 4:
      (i)  "ELIGIBLE LIABILITIES" and "SPECIAL DEPOSITS" have the
           meanings given to them at the time of application of the formula by
           the Bank of England; and
      (ii) "RELEVANT PERIOD" in relation to each Interest Period, means:
            (A)  if it is 3 months or less, that Interest Period;
                 or
            (B)  if it is more than 3 months 3 months.
   113
                                      112
(c)   In the application of the formula, B, Y, L, X, S and Z are included in the
      formula as figures and not as percentages, e.g. if B = 0.5% and Y = 15%,
      BY is calculated as 0.5 x 15.
(d)   (i)   The formula is applied on the first day of each relevant period
            comprised in the relevant Interest Period.
      (ii)  Each rate calculated in accordance with the formula is, if
            necessary, rounded upward to four decimal places.
(e)   If the Agent reasonably determines that a change in circumstances has
      rendered, or will render, the formula inappropriate, the Agent (after
      consultation with the Banks) shall notify the Borrower of the manner in
      which the MLA Cost will subsequently be calculated.  The manner of
      calculation so notified by the Agent shall, in the absence of manifest
      error, be binding on all the Parties.
