      obligations hereunder, nor shall such failure release any other Bank from
      performing its obligations hereunder upon the terms and subject to the
      conditions hereof. If any Bank fails to perform its obligations hereunder,
      the Agent and such Bank shall (without any liability on its part to take
      over any or all of such Bank's commitment or obligations hereunder) use
      its reasonable efforts for a period of up to 28 days to replace such Bank
      with another Qualifying Issuer willing to perform such Bank's obligations
      hereunder.

            Date;

      (iii) the proposed date for the making of such Utilisation is not less
            than ten business days after the date upon which the previous

<PAGE>

      (v)      the proposed amount of such Utilisation is an amount which is no

      (vii)    unless waived by the Majority Banks, no Event of Default or
               Potential Event of Default (other than under Clause 22.27 in
               respect of a Utilisation for the purposes set out in Clause
               22.27) has occurred and is continuing and the representations set
               out in Clause 20 (Representations) are true on and as of the
               proposed date for the making of such Utilisation;

      (viii)   the Agent has received a revised Project Forecast from the
               Borrower demonstrating that:

               (a)   following the making of such Utilisation:

                     (1)   the Bank Loan Life Cover Ratio shall not be less than
                           1.27:1;

                     (2)   the Forecast Annual Debt Service Cover Ratio at all
                           times from the date of such Utilisation shall not be
                           less than 1.16:1;

                     (3)   the EIB Loan Life Cover Ratio shall not be less than

                     less than 1.16:1.

4.2   DEBT SERVICE RESERVE ACCOUNT

      The Senior Facility Agent shall:

      (i)   prior to the making of any Utilisation, calculate the amount
            contemplated in Clause 13.2(i) of the Intercreditor Agreement (and
            for the purposes of such calculation, the Utilisation to be made
            shall be deemed to have been made on the immediately preceding
            Payment Date);

      (ii)  deduct from such Utilisation deposit directly into the 3 Month DSRA
            Sub-Account such amount as is required to ensure that the balance
            standing to the credit of the Debt Service Reserve Account is
            equivalent to one half of the amount calculated pursuant to Clause
            4.2(i) above; and

      (iii) if the purpose of the Utilisation is to make the payment
            contemplated in Clause 22.27(ii)(3) of this Agreement, deposit the
            balance into the Claims Reserve

                                       18
<PAGE>

            Account or, if the purpose of the Utilisation is for any other
            purpose, deposit the balance into the Company Account.

4.3   CALCULATION OF THE AVAILABLE TRANCHE A BALANCE

      The Available Tranche A Balance on any Utilisation Date shall be
      calculated by application of the formula set out below:

      (i)   the Tranche A Balance as reduced on each Repayment Date preceding
            that Utilisation Date by the percentage set opposite each Repayment
            Date(s) in Schedule 9,

      less

      (ii)  the sum of the amounts calculated in accordance with this Clause
            4.3(ii) in respect of each Utilisation made prior to the Utilisation
            Date upon which the Available Tranche A Balance is being calculated,
            to be calculated as follows:

                                         100% - (the sum of each percentage in
                                         Schedule 9 applying from the First
                                  X      Repayment Date to the Utilisation Date
                                         upon which this calculation is to be
                                         made (both inclusive))

         Amount of Utilisation A
      -----------------------------
      100% - (the sum of each
      percentage in Schedule 9
      applying from the First
      Repayment Date to the Repayment
      Date immediately preceding the
      date upon which Utilisation A was
      made (both inclusive))

      where:

      A    =    each single Utilisation made prior to the Utilisation Date upon
                which the Available Tranche A Balance is being calculated.

5.    LETTERS OF CREDIT

5.1   LIABILITY

      The face value of each Letter of Credit shall be allocated to, and
      apportioned among, the Banks in the same proportion as that Bank's Tranche
      A Outstandings bear to the

                                       19
<PAGE>

      aggregate of the Tranche A Outstandings of all the Banks (each such amount
      so allocated in respect of a Letter of Credit, a "PORTION").

5.2   DRAWINGS UNDER LETTERS OF CREDIT

      (i)   NOTIFICATION

            As soon as practicable after receipt by the Agent, the Issuing Bank
            or any Bank (and if by the Issuing Bank or a Bank then the Issuing
            Bank or such Bank shall forthwith notify the Agent thereof) of
            notice from EIB of its intention to make a drawing under any Letter
            of Credit, the Agent shall notify all the Banks thereof and on
            receipt by it of all documents required for a drawing under such
            Letter of Credit, the Agent shall not less than two business days
            prior to the due date for payment of such drawing notify each Bank
            of the amount, and due date for payment, of such Bank's Portion of
            such drawing and each Bank will, on the due date for payment of such
            drawing, make the amount so notified to it (less such Bank's share
            of any amount standing to the credit of the Cash Collateral Account
            in respect thereof) available through its Lending Office by payment
            thereof in sterling to the Agent.

      (ii)  APPLICATION

            The Agent shall apply any amount paid to it pursuant to Clause
            5.2(i) (or standing to the credit of the Cash Collateral Account as
            aforesaid) in payment of the drawing under the relevant Letter of
            Credit on behalf of the Banks.

      (iii) CONVERSION TO TRANCHE B ADVANCE

            Amounts made available by the Banks to the Agent pursuant to Clause
            5.2(i) and applied by the Agent in the manner referred to in Clause
            5.2(ii) shall together constitute one Advance and shall be deemed to
            have been made by the Banks to the Borrower on and subject to the
            terms and conditions hereof and on the basis that:

            (a)   any such Advance shall be repayable by the Borrower on the
                  demand of the Agent (and, for the avoidance of doubt, shall
                  not then be available for reborrowing); and

            (b)   save as provided in Clause 7.2, the provisions of Clauses 7
                  (Interest) and 8 (Alternative Interest Rates) shall apply
                  mutatis mutandis to the calculation and payment of interest on
                  each such Advance.

6.    COUNTER-INDEMNITY

6.1   INDEMNITY

      The Borrower agrees to keep each Finance Party indemnified against all
      actions, proceedings, liabilities, claims, demands, damages, costs and
      expenses in relation to or

                                       20
<PAGE>

      arising out of or in connection with any of the Letters of Credit whether
      thereunder or hereunder and to pay to the Agent (subject to Clause
      5.2(iii) (Conversion to Tranche B Advance)) on demand for the account of
      the party being indemnified all payments, losses, costs, charges, damages
      and expenses suffered or incurred by any Finance Party in consequence of
      any of the Letters of Credit or arising directly or indirectly therefrom.

6.2   PAYMENTS

      The Borrower hereby irrevocably authorises and directs the Agent, the
      Issuing Bank and the Banks to make payments and comply with any demand
      which may be claimed or made or appears on its face to be claimed or made
      under any Letter of Credit without any reference to or further authority,
      confirmation or verification from the Borrower and agrees that any payment
      which the Agent, the Issuing Bank or any Bank shall make in accordance, or
      appearing on its face to be in accordance, with any Letter of Credit shall
      be binding upon the Borrower and shall be accepted by the Borrower as
      conclusive evidence that the Agent, the Issuing Bank or the relevant Bank
      was liable to make such payment or comply with such demand.

6.3   DEMANDS

      The Borrower agrees (without prejudice to any other provision of this
      counter-indemnity) that any demand made upon the Agent, the Issuing Bank
      or any Bank for payment of sums specified in any Letter of Credit shall
      for all purposes relating to this counter-indemnity be deemed to be a
      valid and effective demand and the Agent, the Issuing Bank and the Banks
      shall be entitled to treat it as such notwithstanding any actual lack of
      authority on the part of the person making the demand, if the demand
      appears on its face to be in order.

7.    INTEREST

7.1   INTEREST PERIODS

      The period for which an Advance is outstanding shall be divided into
      successive periods each of which (other than the first, which shall start
      on the date on which such Advance is drawn) shall start on the last day of
      its preceding such period.

7.2   DURATION

      The duration of each Interest Period relating to an Advance shall, save as
      otherwise provided herein, be six months (or of such other duration as the
      Borrower and the Agent may from time to time agree) Provided that:

      (i)   in relation to an Advance made under the Hedged Portion, each
            Interest Period relating thereto shall be of a duration of six
            months, Provided that an Interest Period ending in a month in which
            there is a Hedge Payment Date shall be of such duration that it ends
            on that Hedge Payment Date (or, if more than one, that Hedge Payment
            Date agreed between the Agent and the Borrower) and, notwithstanding
            the foregoing, all then subsisting Interest Periods shall end on the
            First Repayment Date and each Interest Period thereafter shall be of
            a duration of six months ending on a Repayment Date;

      (ii)  in relation to an Advance made under the Unhedged Portion, each
            Interest Period shall be of a duration of six months (or such other
            period as may be agreed between the Agent and the Borrower) and each
            such Interest Period (other than those ending six months or more
            prior to the First Repayment Date) shall end on a Repayment Date;

      (iii) if any Advance has been made pursuant to Clause 5.2(iii) (Conversion
            to Tranche B Advance) the duration of the first Interest Period
            relating to such Advance shall be 7 days;

      (iv)  the first Interest Period after the Amendment Date shall commence on
            the Amendment Date and end on 30 September 2001; and

      (v)   the first Interest Period of each Advance made under the Tranche A
            Balance shall commence on the date of such Advance and end on the
            first Repayment Date immediately following the making of such
            Advance.

7.3   CALCULATION OF INTEREST

      The rate of interest applicable to an Advance during each Interest Period
      relating thereto shall be the rate per annum which is the sum of the
      Applicable Margin, the Mandatory Costs Rate in respect thereof at such
      time and LIBOR on the Quotation Date therefor.

                                       22
<PAGE>

7.4   PAYMENT OF INTEREST

      On each Interest Payment Date the Borrower shall pay accrued interest on
      the Advance to which such Interest Period relates.

8.    ALTERNATIVE INTEREST RATES

8.1   MARKET DISRUPTION

      If:

      (i)   the Agent determines that at or about 11.00 a.m. (London time) on
            the Quotation Date for an Interest Period none or only one of the
            Reference Banks was being offered by prime banks in the London
            Interbank Market sterling deposits in the amount and for the period
            required for the purposes of Clause 7.3 (Calculation of Interest);
            or

      (ii)  before the close of business in London on the first day of an
            Interest Period the Agent has been notified by each of a group of
            Banks to whom in aggregate thirty five per cent. or more of the
            relevant Advance is (or, if such Advance were then made, would be)
            owed that the arithmetic mean referred to in the definition of LIBOR
            in Clause 1.1 (Definitions) does not accurately reflect the cost to
            it of obtaining such deposits,

      then, notwithstanding the provisions of Clause 7 (Interest) (and until any
      substitute basis for determining rates of interest has been agreed in
      accordance with the terms of Clause 8.2 in respect of the event which
      caused this Clause 8 to apply in respect of a particular Interest Period
      or, as the case may be, such Advance):

            (a)   (if paragraph (i) above applies) the duration of the relevant
                  Interest Period (other than one to which proviso (iii) to
                  Clause 7.2 applies, the duration of which shall remain seven
                  days) shall be one month or such lesser duration as shall
                  cause it to end on the next Repayment Date; and

            (b)   (if paragraph (i) or (ii) above applies) during such Interest
                  Period the rate of interest applicable to the Advance to which
                  such Interest Period relates shall be the rate per annum which
                  is the sum of the Applicable Margin, the Associated Costs Rate
                  in respect thereof at such time and the rate per annum
                  determined by the Agent to be the weighted average of the
                  rates (as notified in writing to the Agent before the last day
                  of each Interest Period to which this Clause 8.1 applies)
                  which express as a percentage rate per annum the cost to each
                  Bank of funding from the London Interbank Market (or, if more
                  practicable, from whatever other sources and in whatever
                  manner it may reasonably select) its portion of such Advance
                  during such Interest Period.

<PAGE>

8.2   SUBSTITUTE BASIS

      If either of those events mentioned at paragraphs (a) and (b) in Clause
      8.1 occurs:

      (i)   the Agent shall promptly notify the Borrower and the Banks of such
            event; and

      (ii)  within five days of such notification the Agent and the Borrower
            shall enter into negotiations in good faith with a view to agreeing
            a substitute basis (a) for determining the rates of interest from
            time to time applicable to the Advances and/or (b) upon which the
            Advances may be maintained (whether in sterling or some other
            currency) thereafter and any agreement resulting from any such
            negotiations shall take effect in accordance with its terms Provided
            that the Agent may not agree any substitute basis without the prior
            consent of each Bank.

8.3   DISTRIBUTION TO BANKS

      Interest on an Advance during an Interest Period relating thereto
      calculated at the rate specified in Clause 8.1(ii)(b) shall be distributed
      by the Agent to the Banks in proportion to the amounts which represent the
      cost to each Bank of funding its share of such Advance during such
      Interest Period provided that any such interest which is attributable to
      the Applicable Margin shall be distributed by the Agent to the Banks in
      proportion to their respective shares of such Advance.

9.    CANCELLATION

9.1   The Borrower may, on 14 days prior written notice to the Agent, cancel the
      whole or any part of the Available Tranche A Balance.

9.2   Any Available Tranche A Balance remaining undrawn at the end of the
      Availability Period shall be automatically cancelled on such date.

9.3   The Borrower shall not be entitled to reborrow any part of the Available
      Tranche A Balance cancelled in accordance with this Clause 9.

10.   REPAYMENT

      Without prejudice to the Borrower's obligation to repay any relevant
      Advance at any time referred to in Clause 5.2(iii) (Conversion to Tranche
      B Advance), the Borrower shall:

10.1  repay Tranche A Advances on each Repayment Date (the first repayment
      instalment to be made on the First Repayment Date and each subsequent
      repayment instalment to be made on each subsequent Repayment Date) as

      (i)   repay all Tranche A Advances made on or prior to the Amendment Date
            by repaying a percentage of the aggregate total amount of such
            Advances outstanding as at the Amendment Date, being the percentage
            set opposite such Repayment Date in Schedule 9;

      (ii)  for each Utilisation, the percentage set opposite such Repayment
            Date in Schedule 9 multiplied by the amount calculated as follows:

                              Amount of Utilisation
                 ----------------------------------------------
                 100% - (the sum of each percentage in Schedule
                 9 applying from the First Repayment Date to the
                 Repayment Date immediately preceding the date
                 upon which Utilisation was made (both inclusive))

10.2  repay Advances made under the Tranche B Facility in accordance with Clause
      5.2(iii) (Conversion to Tranche B Advance).

11.   ILLEGALITY

11.1  LIABILITIES UNDER LETTER OF CREDIT

      If as a consequence of the adoption of, or any change in the
      interpretation or administration of, any applicable law or regulation
      after the date hereof it becomes unlawful, or contrary to any regulation
      for the Issuing Bank or a Bank to remain under any actual or contingent
      liability in respect of a Letter of Credit, the Borrower shall

                                       25
<PAGE>

      within fourteen days of receipt by it of a notice to that effect from the
      Agent procure release of the Issuing Bank/Bank from the relevant
      liability, failing which the Borrower shall within seven days after demand
      by the Agent, deposit into a cash collateral account (the "CASH COLLATERAL
      ACCOUNT") opened by the Borrower on or before the date of this Agreement
      with the Account Bank an amount equal to its actual or contingent
      liability in respect of such Letter of Credit Provided that, if the
      Borrower has made a deposit as aforesaid and the Agent is satisfied
      thereafter that such illegality has ceased to apply (and subject to no
      Event of Default or Potential Event of Default having occurred) the Agent
      shall, at the request and cost of the Borrower, release such amount to the
      Borrower.

11.2  FUNDING OF ADVANCES

      If as a consequence of the adoption of, or any change in the
      interpretation or administration of, any applicable law or regulation
      after the date hereof it becomes unlawful, or contrary to any regulation,
      for a Bank to allow to remain outstanding all or any of its portion of an
      Advance made hereunder, then if the Agent on the instructions of such Bank
      so requires, the Borrower shall within the period necessary to comply with
      the law repay such Bank's share of the Loan together with accrued interest
      thereon.

11.3  LOSS OF QUALIFYING ISSUER STATUS

      If any Bank ceases to be a Qualifying Issuer or any Bank suffers an event
      described in Clause 9.1(e)(i), (ii) or (iii) of the EIB Facility
      Agreement, such Bank shall promptly notify the Agent whereupon whilst such
      Bank remains a non-Qualifying Issuer or subject to such an event:

      (i)   each Bank hereby agrees that (to the extent it is lawful to do so)
            if it ceases to be a Qualifying Issuer and does not, within 45 days
            of a demand from EIB served upon the Agent pursuant to Clause 9.1(g)
            of the EIB Facility Agreement, effect a transfer pursuant to Part 12
            of all of its rights and obligations to a bank or financial
            institution which is a Qualifying Issuer, it shall establish, fund
            and maintain a cash collateral account (each such account herein
            referred to as an "EIB/ISSUER CASH COLLATERAL ACCOUNT") which
            account shall be subject to the terms of this Clause 11.3, for so
            long as it shall continue to be a Bank which is not a Qualifying
            Issuer, no transfer has been effected as aforesaid subsequently and
            the same has not been released under Clause 12 of the EIB Facility
            Agreement;

      (ii)  any EIB/Issuer Cash Collateral Account will be an account in the
            name of such Bank with a bank or financial institution in London,
            being a bank or financial institution proposed by such Bank and
            approved by EIB (such approval not to be unreasonably withheld or
            delayed and not be withheld if such bank or financial institution is
            itself a Qualifying Issuer);

      (iii) the cash collateral amount to be deposited in any such EIB/Issuer
            Cash Collateral Account shall:

                                       26
<PAGE>

            (a)   be in an original principal amount equal to, and thereafter be
                  reduced or, as the case may be, increased to the amount from
                  time to time equal to, such Bank's Portion of issued and
                  outstanding Letters of Credit; and

            (b)   bear interest at such term deposit rate as such Bank is able
                  to negotiate with the relevant bank or financial institution
                  with which such EIB/Issuer Cash Collateral Account is
                  maintained;

      (iv)  any amount by which the amount standing to the credit of EIB/Issuer
            Cash Collateral Account exceeds the amount which at such time is
            required to be standing to the credit thereof by virtue of paragraph
            (iii)(a) above (whether such amount represents interest paid on such
            account or a part of the original or any subsequent amount credited
            thereto by the Bank) shall, upon request by such Bank, be paid to
            such Bank;

      (v)   the cash collateral deposit in the EIB/issuer Cash Collateral
            Account will be assigned or pledged by such Bank in favour of EIB by
            way of first ranking security in form and substance satisfactory to
            EIB (acting reasonably);

      (vi)  such Bank shall be entitled to receive the L/C Commission under
            Clause 28.2 (LIC Commission), notwithstanding that it has ceased to
            be a Qualifying Issuer and notwithstanding that its Portion of the
            Letters of Credit may have been cancelled, whilst it is providing
            replacement cash collateral in the EIB Issuer Cash Collateral
            Account and such LJC Commission shall be calculated on the amount
            deposited in such account by such Bank; and

      (vii) in the event that EIB makes demand in respect of such Bank's Portion
            of issued and outstanding Letters of Credit, then notwithstanding
            any other provision of this Agreement, that Bank shall be solely
            liable in respect of such demand.

11.4  DEMAND FOR PAYMENT OF INTEREST

      In the event that EIB makes demand under any issued and outstanding
      Letters of Credit in respect of the interest portion of such Letter of
      Credit, and any Bank fails to makes its Portion of such demand available
      to the Agent in accordance with Clause 5.2 (Drawings under Letters of
      Credit), then notwithstanding any other provision of this Agreement, such
      Bank will be solely liable in respect of its Portion of such demand.

12.   PREPAYMENT

      The Borrower shall at all times comply with the provisions set out in
      Clause 23 of the Intercreditor Agreement.

                            CHANGES IN CIRCUMSTANCES

13.   TAXES

13.1  TAX GROSS-UP

      Subject to Clause 13.6 below, all payments to be made by the Borrower
      hereunder shall be made free and clear of and without deduction or
      withholding for or on account of tax unless required by law. If the
      Borrower is so required on account of any Relevant Tax to make any
      deduction or withholding from any sum payable by it to or for the account
      of any person ("THE RECIPIENT") hereunder or if the recipient or the Agent
      on its behalf is required to pay any Relevant Tax (other than tax on its
      overall net income) imposed, levied, collected or assessed directly on it
      in respect of any payment receivable by it under this Agreement:

      (i)   the Borrower shall notify the Agent of any such requirement or any
            change in any such requirement as soon as the Borrower becomes aware
            of it or, as the case may be, the recipient will forthwith notify
            the Borrower of its liability to such tax as soon as it becomes
            aware of such liability;

      (ii)  the Borrower, the Agent or the recipient (as the case may be) shall
            pay any such tax to the relevant authority in full within the time
            allowed for such payment under applicable law and, without prejudice
            to the foregoing, before the date on which penalties attach thereto;
            and

      (iii) the sum payable by the Borrower in respect of which the relevant
            deduction, withholding or payment is required shall be increased to
            the extent necessary to ensure that, after the making of that
            deduction, withholding or payment, that person receives on the due
            date and retains (free from any liability in respect of any such
            deduction, withholding or payment) a net sum equal to what it would
            have received had no such deduction, withholding or payment been
            required or made.

13.2  DELIVERY OF RECEIPT

      The Borrower shall after it has made any payment of tax referred to in
      Clause 13.1(ii) to the applicable authority use all reasonable endeavours
      to deliver to the Agent an original receipt (or a certified copy thereof)
      issued by such authority evidencing such payment as soon as possible.

13.3  INDEMNITY

      Without prejudice to the provisions of Clause 13.1 but subject to Clause
      13.7, if as a consequence of the adoption of, or any change, or change in
      the judicial interpretation or administration in accordance with published
      practice of, any applicable law, regulation or provision after the date
      hereof, any Finance Party or the Agent on its behalf is required by any
      law or regulation to make any payment, whether on account of tax (other
      than tax, or

                                       28
<PAGE>

      an increase in the rate of tax, on its overall net income) or otherwise,
      on or in relation to any sum received or receivable by such person
      hereunder, or any liability in respect of any such payment is asserted,
      imposed, levied or assessed against such person, then the Borrower shall
      upon demand pay to the Agent for its own account or (as the case may be)
      for the account of such person an amount sufficient to indemnify such
      person against such payment or liability, together with any interest,
      penalties and expenses payable or incurred in connection therewith
      Provided that the Borrower shall not be required to pay any increased
      amount to compensate any person for any penalty incurred by such person by
      reason of such person failing to make timely payment of tax to the
      relevant authorities in circumstances where such person had itself
      received an amount equal to such tax from the Borrower prior to the due
      date for payment thereof to such authorities. If the Agent or any such
      person makes any payment of tax referred to in Clause 13.1(ii) or in this
      Clause 13.3 it shall promptly on receipt thereof use all reasonable
      endeavours to deliver to the Borrower an original receipt (or a certified
      copy thereof) issued by the relevant authority evidencing such payment as
      soon as possible.

13.4  NOTIFICATION

      Any person intending to make a claim pursuant to Clause 13.3 shall notify
      the Agent of the event by reason of which it is entitled to do so and
      provide it with supporting evidence where practicable, whereupon the Agent
      shall notify the Borrower thereof.

13.5  RELEVANT TAX

      For the purposes of this Clause 13 "RELEVANT TAX" in relation to any
      payment which falls to be made hereunder means any present or future taxes
      of any nature now or hereafter imposed by the laws of the United Kingdom.

13.6  EXCEPTION TO GROSS-UP

      If on the date that a payment becomes due hereunder to or for the account
      of a recipient:

      (iii) a Finance Party is a Treaty Lender and the Treaty Lender did not
            comply with Clause 13.10 below; or

      (iv)  a Finance Party is not a Qualifying Lender or, at any time on or
            after the date of this Agreement but prior to such payment becoming
            due, a Finance Party is not or ceases to be a Qualifying Lender;

      and, as a result, the Borrower is required to make the aforementioned
      payment subject to a deduction or withholding on account of tax, the
      Borrower shall not be under an obligation to pay an additional amount to
      or for the account of that recipient under Clause 13.1 except as provided
      in Clause 13.8.

                                       29
<PAGE>

13.7  EXCEPTION TO TAX INDEMNITY

      If:

      (i)   on the date on which a payment on account of tax is made or a tax
            liability arises, a Finance Party is not a Qualifying Lender or, at
            any time on or after the date of this Agreement but prior to that
            date, a Finance Party is not or ceases to be a Qualifying Lender;
            and

      (ii)  such payment or liability would have been reduced if the relevant
            Finance Party had been a Qualifying Lender at the relevant time,

      any liability of the Borrower to indemnify the relevant Finance Party
      pursuant to Clause 13.3 shall be correspondingly reduced except as
      provided in Clause 13.8.

13.8  CONDITIONS TO EXCEPTIONS

      Clauses 13.6 and 13.7 shall not relieve the Borrower from making payments
      or increased payments under Clauses 13.1 or 13.3 if:

      (i)   there shall have been any Tax Change and as a result thereof the
            relevant Finance Party ceases to be a Qualifying Lender; or

      (ii)  the Borrower would be obliged to make a payment, or increased
            payment, of the same amount under Clauses 13.1 or 13.3 irrespective
            of whether any Finance Party is at any time on or after the date
            hereof a Qualifying Lender; or

      (iii) such payments or increased payments become due as a result of the
            Borrower becoming resident outside its Residence Jurisdiction for
            tax purposes.

13.9  QUALIFYING LENDER

      Any Bank which ceases, for whatever reason, to be a Qualifying Lender
      shall promptly notify the Borrower of that change in its status.

13.10 TREATY LENDER

      The Agent, a Treaty Lender and the Borrower which makes a payment to which
      that Treaty Lender is entitled shall each cooperate in completing any
      procedural formalities they are able to complete which are necessary for
      the Borrower to obtain authorisation to make that payment without a
      deduction or withholding on account of tax.

13.11 TAX CREDIT

      If the Borrower pays any additional amount under Clause 13.1(iii) or any
      amount under Clause 13.3 (a "TAX PAYMENT") and any recipient of a Tax
      Payment (the "RECIPIENT") effectively obtains a refund of tax, or credit
      against tax on its overall net income, by reason of that Tax Payment ("TAX
      CREDIT"), and the Recipient is able to identify the Tax

                                       30
<PAGE>

      Credit as being attributable in whole or in part to the Tax Payment, then
      the Recipient shall pay to the Agent, for reimbursement to the Borrower,
      such amount as it shall determine to be the proportion of the Tax Credit
      as will leave the Recipient, after that reimbursement, in no better or
      worse position than it would have been in if the Tax Payment had not been
      required. Each Recipient shall have an absolute discretion as to whether
      to claim any Tax Credit and, if it does so claim, the extent, order and
      manner in which it does so. No Recipient shall be obliged to disclose any
      information regarding its tax affairs or computations to the Borrower.
      Nothing in this Clause 13.11 shall interfere with the right of each
      Recipient to arrange its tax affairs in whatever manner it thinks fit.

      applicable law or regulation after the date hereof and/or (b) compliance
      with any request from or requirement made after the date hereof of any

      Rate) or other fiscal, monetary or other financial authority (whether or
      not having the force of law but, if not having the force of law, being a
      request or requirement which is customarily complied with by banks):

      (i)   a Finance Party incurs a cost (other than tax, or an increase in
            tax, on its overall net income) as a result of its having entered
            into and/or performing its obligations under this Agreement and/or

            hereunder;

      (ii)  by reason of capital adequacy requirements the rate of return on the

      Agent for account of that Finance Party an amount sufficient to indemnify
      it against, as the case may be, (i) such cost, (ii) such proportion of

      hereunder and/or under any Letter of Credit, (iii) such

                                       32
<PAGE>

      portion of such increased cost as is attributable to its making, funding
      or maintaining advances hereunder and/or maintaining its actual or
      contingent liability under any Letter of Credit, (iv) such liability, or

            Basle Committee on Banking Regulations and Supervisory Practices; or

      (iv)  any cost, reduction or increased cost which results from a deduction
            or withholding for or on account of tax or from a payment on account

      Gross-up) it shall notify the Agent of the event by reason of which it is
      entitled to do so and provide the Agent with supporting evidence where
      practicable, whereupon the Agent shall notify the Borrower thereof.

14.4  MITIGATION

      If circumstances arise which would or would upon the giving of notice
      result in:

      (i)   an amount becoming payable under Clause 13.1(iii) (Tax Gross-up) or
            a claim for indemnification by a Finance Party or the Agent pursuant
            to Clause 13.3 (Indemnity) or Clause 14 (Increased Costs); or

      (ii)  a determination or notification pursuant to Clause 8.1(ii)(b)
            (Market Disruption),

      then, without in any way limiting, reducing or otherwise qualifying the
      Borrower's obligations under any of the Clauses referred to in
      sub-paragraphs (i) to (iii) above, such Finance Party shall notify the
      Agent thereof (which shall, in turn, promptly notify the Borrower thereof)
      and, in consultation with the Agent and the Borrower, make reasonable
      efforts to mitigate the effects of such circumstances including the
      transfer of a Bank's rights and obligations hereunder to another financial
      institution (including, without

                                       33

      environmental law, decree, regulation, civil action or penal notice which
      such liability would not have been incurred by such person if such person
      was not party to the arrangements established under or pursuant to the
      Relevant Documents in the capacity or capacities in which such person is
      from time to time so party and within thirty days of notification thereof
      to the Borrower no proposal has been made by the Borrower which is

22.25 CONSENTS ETC

      Any consent, licence, permit, approval or authorisation in relation to the

22.26 TOTAL LOSS

      The whole or any material part of the Project is assessed by the relevant
      insurers to constitute a total loss for insurance purposes.

22.27 NO MATERIAL PROCEEDINGS

      (i)   Any actions or administrative proceedings of or before any court or
            agency have been started or threatened which could reasonably be
            expected to have a Material Adverse Effect, other than in relation
            to the Part 1 Liabilities.

      (ii)  If, in relation to the Part 1 Liabilities:

            (1)   a first judgment is granted against the Borrower in favour of
                  the Secretary of State in an amount (the "Judgment Amount")
                  which together with all outstanding costs, fees and expenses
                  relating thereto for which the Borrower is or will be liable,
                  is in excess of the amount then standing to the credit of the
                  Claims Reserve Account;

            (2)   a project forecast (prepared by utilising the Financial Model
                  in substantially the same form as the then current Financial
                  Model but adjusted to take into account the amount in excess
                  of the Claims Reserve Account and any other adjustments which
                  the Agent, acting reasonably following consultation with the
                  Borrower) shows that at any time prior to the Final Repayment
                  Date an Event of Default as set out in Clause 22.23 of this
                  Agreement or Clause 10.1(e) of the EIB Facility Agreement has
                  occurred or will occur; and

            (3)   either the Borrower or the shareholders of the Borrower do not
                  within 30 days of notification by the Agent that the project
                  forecast prepared in accordance with Clause 22.27(ii)(2) shows
                  that an Event of Default as set out in Clause 22.23 of this
                  Agreement or Clause 10.1(e) of the EIB Facility Agreement has
                  occurred or will occur, deposit into the Claims Reserve
                  Account an amount required to ensure that such Event of
                  Default is immediately remedied or shall not occur.

      For the purposes of this Clause 22.27(ii):

      (a)   the provisions of Clause 19 of the Intercreditor Agreement shall not
            apply; and

      (b)   the project forecast shall be prepared by the Agent; and

      (c)   the Borrower shall promptly upon being requested to do so by the
            Agent, provide the Agent with a reasonable estimate of all
            outstanding costs, fees and expenses contemplated in Clause
            22.27(ii)(1).

22.28 ACCELERATION AND CANCELLATION

      Upon the occurrence of an Event of Default and at any time thereafter if
      the Event of Default is continuing, the Agent (if so instructed by
      Majority Banks and subject to Clause 28.2 of the Intercreditor Agreement)
      shall, by written notice to the Borrower:

      (i)   declare the Advances to be immediately due and payable (whereupon
            the same shall become so payable together with accrued interest
            thereon and any other sums then owed by the Borrower hereunder) or
            declare the Advances to be due and payable on demand of the Agent;
            and/or

      (ii)  require the Borrower to deposit (and the Borrower shall forthwith so
            deposit) into the Cash Collateral Account an amount equal to the
            maximum aggregate actual and contingent liability of each Bank and
            the Issuing Bank under the Letters of Credit; and/or

      (iii) require the Security Trustee to exercise any and all such rights as
            may be available to it under any of the Security Documents and/or
            require the Intercreditor Agent to exercise any and all such rights
            (including step-in rights) as may be available to it under the
            Direct Agreement.

22.29 ADVANCES DUE ON DEMAND

      If, pursuant to Clause 22.28 (Acceleration and Cancellation), the Agent
      declares the Advances to be due and payable on demand of the Agent or
      pursuant to Clause 5.2(iii) (Conversion to Tranche B Advance) an Advance
      is repayable on demand of the Agent, then, and at any time thereafter, the
      Agent (if so instructed by Majority Banks and subject to Clause 28.2 of
      the Intercreditor Agreement) shall by written notice to the Borrower:

      (i)   require repayment of the Advances on such date as it may specify in
            such notice (whereupon the same shall become due and payable on such
            date together with accrued interest thereon and any other sums then
            owed by the Borrower hereunder) or withdraw its declaration with
            effect from such date as it may specify in such notice; and/or

      (ii)  select as the duration of any Interest Period which begins whilst
            such declaration remains in effect a period of six months or less.

22.30 PROMOTER AND RELEVANT GROUP COMPANY

      If any of the events referred to in Clause 22.6 to 22.10 occurs in
      relation to a Promoter or a Relevant Group Company it shall not thereby
      constitute an Event of Default unless the event in question is reasonably
      likely to have a Material Adverse Effect or to materially affect the
      interests of the Finance Parties (after taking account of the ability of
      the other Promoter or Relevant Group Companies (as the case may be) to
      which the events have not occurred to comply with their respective
      obligations under the Relevant Documents).

      of the preceding such Interest Period and the duration of each of which
      shall be selected by the Agent (having regard to the likely period of the
      default) Provided that the first Interest Period relating to an Unpaid Sum
      which is all or part of an Advance which became due and payable otherwise

      Agent for account of that Bank within seven days of demand such an amount
      equal to the amount (if any) by which (a) the additional interest which
      would have been payable on the amount so received or recovered had it been
      received or recovered on the last day of that Interest Period exceeds (b)
      the amount of interest which in the reasonable opinion of the Agent would
      have been payable to the Agent on the last day of that Interest Period in
      respect of a sterling deposit equal to the amount so received or recovered

27.1  REDISTRIBUTION OF PAYMENTS

      If at any time the proportion which any Bank (a "RECOVERING BANK") has
      received or recovered (whether by payment, exercise of a right of set-off
      or otherwise) in respect of its portion of any payment to be made under
      this Agreement by the Borrower for account of such Bank and one or more
      other Banks ("THE RELEVANT PAYMENT") is greater (the amount of the excess
      being herein called "THE EXCESS AMOUNT") than the proportion thereof
      received or recovered by the Bank or Banks receiving or recovering the
      smallest proportion thereof (which shall include a nil receipt), then:

      (i)   such Recovering Bank shall promptly pay to the Agent an amount equal
            to the excess amount;

      (ii)  there shall thereupon fall due from the Borrower an amount equal to
            the amount paid out by such Recovering Bank pursuant to paragraph
            (i), the amount so due being, for the purposes of this Clause,
            treated as if it were an unpaid part of such Recovering Bank's
            portion of the relevant payment; and

      (iii) the Agent shall treat the amount received by it from such Recovering
            Bank pursuant to paragraph (i) as if such amount had been received
            by it from the Borrower in respect of the relevant payment and shall
            pay the same to the persons entitled thereto (including such
            Recovering Bank) pro rata to their respective entitlements thereto,

      Provided always that this Clause 27.1 shall not oblige the Borrower at any
      time to pay an amount in excess of the aggregate amount of all sums,
      whether actual or contingent, expressed to be then due and payable by the
      Borrower pursuant to the terms of this Agreement.

27.2  REPAYABLE RECOVERIES

      If any sum (a "RELEVANT SUM") received or recovered by a Recovering Bank
      in respect of any amount owing to it by the Borrower becomes repayable and

      (i)   each Bank which has received a share of such relevant sum by reason
            of the implementation of Clause 27.1 (Redistribution of Payments)
            shall, upon request of the Agent, pay to the Agent for account of
            such Recovering Bank an amount equal to its share of such relevant
            sum; and

                                       61
<PAGE>

      (ii)  there shall thereupon fall due from the Borrower to each such Bank
            an amount equal to the amount paid out by it pursuant to paragraph
            (a) above, the amount so due being, for the purposes hereof, treated
            as if it were the sum payable to such Bank against which such Bank's
            share of such relevant sum was applied.

27.3  SHARING AFTER PROCEEDINGS

      If any Bank shall commence any action or proceeding in any court to
      enforce its rights hereunder after consultation with the other Banks and
      with the consent of the Majority Banks (such consent not to be
      unreasonably withheld) and, as a result thereof or in connection
      therewith, shall receive any excess amount (as defined in Clause 27.1),
      then such Bank shall not be required to share any portion of such excess
      amount with any Bank which has the legal right to, but does not, join in
      such action or proceeding or commence and diligently prosecute a separate
      action or proceeding to enforce its rights in another court.

27.4  SET-OFF

      The Borrower authorises each Bank to apply any credit balance to which the
      Borrower is entitled on any account of the Borrower with that Bank in
      satisfaction of any sum due and payable from the Borrower to such Bank
      hereunder but unpaid; for this purpose each Bank is authorised to purchase
      with the monies standing to the credit of any such account such other
      currencies as may be necessary to effect such application. No Bank shall
      be obliged to exercise any right given to it by this Clause, but if it
      does so, it shall promptly notify the Agent, which shall notify the
      Borrower thereof.

            and, if it is to be exercised, as to the manner in which it should
            be exercised; and

                                       66
<PAGE>

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

      (iii) save as otherwise provided herein, act as agent hereunder in
            accordance with any instructions given to it by Majority Banks,
            which instructions shall be binding on all of the Finance Parties;
            and

            actionable at the suit of any person; or

      (iv)  be under any obligations other than those for which express
            provision is made herein.

<PAGE>

30.5  INDEMNIFICATION

      Each Bank shall, from time to time on demand by the Agent, indemnify the
      Agent, in the proportion its share of the Loan (or, if no Advances have
      been made, its Available Commitment) bears to the amount of the Loan (or,
      if no Advances have been made, the Available Facility) at the time of such
      demand (or, if the Loan has then been repaid in full, immediately prior to
      the final repayment thereof), against any and all costs, claims, losses,
      expenses (including legal fees) and liabilities together with any VAT
      thereon which the Agent may incur, otherwise than by reason of its own
      gross negligence or wilful misconduct, in acting in its capacity as agent
      hereunder.

30.6  EXCLUSION OF LIABILITIES

      No Finance Party accepts any responsibility for the accuracy and/or
      completeness of the Information Memorandum or any other information
      supplied in writing or otherwise by the Borrower in connection herewith or

      any of the Finance Documents and no Finance Party shall be under any
      liability as a result of taking or omitting to take any action in relation
      to any of the Finance Documents, save in the case of gross negligence or
      wilful misconduct.

30.7  NO ACTIONS

      Each of the Finance Parties agrees that it will not assert or seek to
      assert against any director, officer or employee of the Agent or the

      matters referred to in Clause 30.6 (Exclusion of Liabilities).

30.8  BUSINESS WITH THE GROUP

      The Agent and the Arranger may accept deposits from, lend money to and
      generally engage in any kind of banking or other business with the
      Borrower, either of the Promoters and each Relevant Group Company (or any
      Affiliate thereof) (including, without limitation, acting as agent or
      otherwise on behalf of any group of banks providing facilities to any of
      the foregoing).

30.9  RESIGNATION

      The Agent may resign its appointment hereunder at any time without
      assigning any reason therefor by giving not less than sixty days' prior
      written notice to that effect to each of the other parties hereto Provided
      that no such resignation shall be effective until a successor for the
      Agent is appointed in accordance with the succeeding provisions of this
      Clause 30.

30.10 SUCCESSOR AGENT

      If the Agent gives notice of its resignation pursuant to Clause 30.9

      successor to the Agent by the Majority Banks

                                       68

      such a successor itself.

30.11 RIGHTS AND OBLIGATIONS

      If a successor to the Agent is appointed under the provisions of Clause
      30.10 (Successor Agent), then (a) the retiring Agent shall be discharged
      from any further obligation hereunder but shall remain entitled to the
      benefit of the provisions of this Clause 30 and (b) its successor and each
      of the other parties hereto shall have the same rights and obligations
      amongst themselves as they would have had if such successor had been a
      party hereto.

30.12 OWN RESPONSIBILITY

      It is understood and agreed by each Finance Party that it has itself been,
      and will continue to be, solely responsible for making its own independent
      appraisal of and investigations into the financial condition,
      creditworthiness, condition, affairs, status and nature of each member of
      the Group and, accordingly, each Bank warrants to the Agent and the
      Arranger that it has not relied on and will not hereafter rely on the
      Agent and the Arranger nor either of them:

      (i)   to check or enquire on its behalf into the adequacy, accuracy or
            completeness of any information provided by the Borrower in
            connection with any of the Finance Documents or the transactions
            herein contemplated (whether or not such information has been or is
            hereafter circulated to such Bank by the Agent and the Arranger or
            either of them); or

      (ii)  to assess or keep under review on its behalf the financial

            the Borrower or any Relevant Group Company.

30.13 AGENCY DIVISION SEPARATE

      In acting as Agent for the other Finance Parties, the Agent shall be
      regarded as acting through its agency division which shall be treated as a
      separate entity from any other of its divisions or departments and,
      notwithstanding the foregoing provisions of this Clause 30, any
      information received by some other division or department of the Agent may
      be treated as confidential and shall not be regarded as having been given
      to the Agent's agency division.

30.14 CONFIDENTIAL INFORMATION

      Notwithstanding anything to the contrary expressed or implied herein and
      without prejudice to the provisions of Clause 30.13 (Agency Division
      Separate), the Agent shall not as between itself and the other Finance
      Parties be bound to disclose to any Bank or other person any information
      which is supplied by the Borrower to the Agent in its capacity as Agent
      for the Finance Parties and which is identified by the Borrower at the
      time it is so supplied as being confidential information Provided that the
      consent of the

                                       69
<PAGE>

      Borrower to such disclosure shall not be required in relation to any
      information which in the opinion of the Agent relates to an Event of

      have given a confidentiality undertaking in a form satisfactory to the
      Agent and the Borrower.

30.15 SYNDICATE MEETINGS

      the Banks; (ii) if authorised by a Relevant Instructing Group, the Agent

      express provisions of this Agreement) at any time convene a meeting of the
      Banks; (iii) whenever the Agent is to convene any such meeting it shall
      forthwith give notice in writing to the Banks of the day, time and place
      thereof and the nature of the business to be transacted thereat; (iv) for
      the purposes of this Clause 30.15 a "RELEVANT INSTRUCTING GROUP" means a

      time to time (i) enter into written amendments, supplements or

      deliver to the Borrower a written instrument waiving prospectively or

      (i)   to the extent that in such Transfer Certificate the Bank party
            thereto seeks to transfer its rights, benefits and/or its
            obligations hereunder as a Bank, the Borrower and such Bank shall
            each be released from further obligations to the other hereunder and

            shall be cancelled (such rights, benefits and obligations being
            referred to in this Clause as "DISCHARGED RIGHTS AND OBLIGATIONS");

      (ii)  the Borrower and the Transferee party thereto shall each assume
            obligations towards and/or acquire rights and benefits from each
            other hereunder which differ from such discharged rights and

            assumed and/or acquired the same in place of the Borrower and such
            Bank;

      (iii) each of the Finance Parties other than the transferring Bank shall
            acquire the same rights and assume the same obligations between
            themselves hereunder as they would have acquired and assumed had
            such Transferee been an original party hereto as a Bank with the
            rights and/or the obligations acquired or assumed by it as a result
            of such transfer; and

      (iv)  such Transferee shall become a party thereto as a "BANK".

31.4  AMOUNT OF TRANSFER

      Any transfer pursuant to Clause 31.3 shall be either such that the
      aggregate amount of the Outstandings thereby transferred (whether Tranche
      A Outstandings, Tranche B

                                       72
<PAGE>

      Outstandings or a combination of the two) is not less than

      this Agreement and such of the information supplied to the Agent and the
      Finance Parties pursuant to or in connection with this Agreement as such
      Finance Party shall consider appropriate Provided that prior to such
      disclosure such potential assignee or person has undertaken in writing to
      the Borrower and the Banks that it will be bound by the terms of Schedule
      7 as if it were a Bank.

31.7  NO ADDITIONAL COSTS

      Where any Finance Party transfers all or any part of its obligations
      hereunder, the Borrower shall not be liable to pay any additional amounts
      under Clauses 13 (Taxes), 14 (Increased Costs) or 29.3 (Taxes etc) which
      would otherwise be payable from the effective date of such assignment or
      transfer as a result thereof and which would not have been payable had no
      such assignment or transfer taken place.

31.8  GLOBAL TRANSFER

      The Finance Parties may, as part of the strategy of the Arranger for
      syndication of the Facility, on a date (the "GLOBAL TRANSFER DATE") to be
      notified to the Borrower by the Agent not less than seven days prior to
      such Global Transfer Date, transfer all or part of their commitments to a
      Transferee pursuant to a transfer agreement (the "GLOBAL TRANSFER
      AGREEMENT") to be executed by the Banks and the Transferees and the
      Borrower in a mutually agreed form. Notwithstanding Clause 31.3, the
      Global Transfer Agreement will be in place of separate Transfer
      Certificates but shall provide for a transfer of all rights and
      obligations relating to the Outstandings transferred on the same basis as
      if individual Transfer Certificates had been entered into by the Banks and
      the Transferees. On the Global Transfer Date, the Banks may enter into
      such subparticipation agreements as are necessary to comply with the
      syndication strategy of the Arranger.

                              ADDITIONAL COSTS RATE

1.    The Mandatory Cost Rate is an addition to the interest rate to compensate
      the Banks for the cost of compliance with the requirements of the
      Financial Services Authority (or any other authority which replaces all or
      any of its functions).

2.    On the first day of each Interest Period (or as soon as possible
      thereafter) the Agent shall calculate, as a percentage rate, a rate (the
      "ADDITIONAL COSTS RATE") for each Bank, in accordance with the formulae
      set out below. The Mandatory Cost Rate will be calculated by the Agent as
      a weighted average of the Banks' Additional Costs Rates (weighted in
      proportion to the percentage participation of each Bank in the relevant
      Advance) and will be expressed as a percentage rate per annum.

3.    The additional cost rate for each Bank will be calculated by the Agent as
      follows:

      (a)   in relation to sterling Advances:

            E x 0.01 per cent. per annum
            --------
              100

      or incorporation with a Facility Office in the same jurisdiction as its
      Facility Office.

      The Agent shall have no liability to any person if such determination
      results in an additional cost rate which over or under compensates any

      any of its functions) and any such determination shall, in the absence of
      manifest error, be conclusive and binding on all the parties hereto.

      disclose only that portion of Confidential Information which we reasonably
      believe ourselves to be compelled legally to so disclose.

      falling on the fifth anniversary of the Termination Date (as defined in
      the DBFO Contract).

      impaired or defeated in whole or in part or which would entitle any
      insurer to refuse to pay any claim under any such insurance policy

      business hours the original policies of Insurances taken out and
      maintained pursuant to this Schedule 8 which are or should be in the

      renewal certificate therefor issued by the insurer which confirms that
      such Insurance is in full force and effect.

4.3   Without prejudice to Clause 4.1 above or Clause 5 below and subject to
      Clause 19.11 of this Agreement, the Borrower shall prior to taking out or
      changing any such Insurance notify the Agent of the identity of the
      insurer and of the principal terms and conditions of such Insurance or any
      version to such terms and conditions.

5.    ALTERATION OF COVERAGE

      The Borrower shall procure that no reductions in limits or coverage
      (including those resulting from extensions) or increases in deductibles,
      exclusions or exceptions shall be made to any Insurance effected pursuant
      hereto without the written consent of the Agent (not to be unreasonably
      withheld).

6.    APPLICATION OF PROCEEDS

      The Borrower shall apply any proceeds received under any of the Insurances
      referred to in this Schedule 8 in accordance with the provisions of Clause
      14 of the Intercreditor Agreement.

7.    DEFAULT BY BORROWER

      If the Borrower fails to comply with any or all of its obligations with
      respect to insurance as required hereunder, the Agent may (but shall not
      be required to) effect or renew any such insurance either in its own name
      or in its name and that of the Borrower jointly or in the name of the
      Borrower with an endorsement of the Agent's interest. All moneys expended
      by the Agent in so effecting or renewing any such insurance shall be
      reimbursed by the Borrower to the Agent on demand and shall carry interest
      from the date of payment by the Agent until so reimbursed at the rate and
      otherwise as mentioned in Clause 23.2 of this Agreement.

8.    MARKET AVAILABILITY

8.1   Notwithstanding the foregoing but save as provided in Clause 8.2 below,
      the Borrower shall not be in breach of its obligations hereunder to the
      extent that:

      (a)   insurances or the level of cover otherwise required to be taken out
            or maintained hereunder are not available owing to lack of capacity
            in the insurance market; or

                                       97
<PAGE>

      (b)   the premiums in respect of any such insurances are unreasonable in
            the opinion of the Insurance Adviser (after consulting with the
            Agent and the Borrower's insurance adviser having regard to the risk
            being covered and the interests of the Banks under the Finance
            Documents); or

      (c)   the Agent, after consultation with the Insurance Adviser and the
            Majority Banks, agrees to waive the benefit of such obligations.

8.2   If in relation to any particular policy the provisions referred to in
      paragraph (6) of Part B or paragraph (6)(v) of Part 3 paragraph 1 of this
      Schedule 8 are not available in the worldwide insurance market or where
      the extra premiums required in respect of the inclusion of such provisions
      are in the reasonable opinion of the Agent excessive for cover of that
      type in the worldwide insurance market, the Borrower and the Agent shall
      negotiate in good faith for a period not exceeding 20 days to determine
      whether an alternative mutually acceptable solution exists and if
      agreement on such a solution is reached it shall be implemented instead of
      the inclusion in such policy of the provisions set out in the said
      paragraph (6) or (6)(v) (as the case may be).

9.    DATA SYSTEM

      The Borrower shall, within 21 days of a request from the Agent (following
      consultation with the Insurance Adviser):

9.1   procure that an information storage and retrieval system ("DATA SYSTEM")
      is established;

            nature or extent of the cover to be provided under any of the
            Insurances and a copy of any additional Project Document entered
            into after the date hereof;

      (ii)  contemporaneously with the delivery to the Agent, copies of any
            information delivered pursuant to Clauses 19.15, 19.16, 19.17, 19.18
            and 19.19 of the Agreement;

9.4   contemporaneously deliver (through the Borrower's insurance broker) to the
      lead insurers on the Contractors' all-risks, advance loss of revenue,
      material damage and loss of revenue policies copies of the documents
      deposited in the Data System pursuant to Clause 9.3 above;

                                       98
<PAGE>

9.5   no later than the 15th business day after delivery of any document to the
      lead insurers under Clause 9.4 above, provide the Insurance Adviser with
      evidence of the insurers' acknowledgement of receipt thereof.

                                POLICY PROVISIONS

1.    GENERAL PROVISIONS

The policies shall include the following provisions substantially in the form
set out below:

(1)   The insurers hereby agree to waive all rights of subrogation howsoever
      arising which they may have or acquire against any of the Lenders and
      their officers, directors, employees and assigns arising out of any
      occurrence in respect of which any claim is admitted hereunder.

(2)   All the provisions of this policy (except those relating to limits of
      liability) shall operate as if there were a separate policy covering each
      insured. Accordingly, the liability of the insurers shall not be
      conditional upon the due observance and fulfilment by any other Insured of
      the terms of this policy and of any duties imposed upon it relating
      thereto and shall not be affected by any failure in such observance of
      fulfilment by any other Insured.

(3)   The Lenders and their respective directors, employees and assigns shall
      (whether or not they are insured parties under the policy) in no
      circumstances be liable for the payment of any premium or to perform any
      other obligation owed to the insurers. The insurers waive all rights of
      contribution against any other insurance effected by the Lenders.

(4)   The Lenders and their respective officers, directors, employees and
      assigns are additional insureds under this policy. In respect of any
      policies covering third party liabilities, the Lenders are to be included
      as an insured.

(5)   The Agent shall be advised:

      (i)   at least 60 days (or such lesser period as may be agreed between the
            Agent, the Insurance Adviser and the Borrower Provided that such
            lesser period shall be a minimum of 30 days) before any cancellation
            is to take effect if any insurer cancels or gives notice of such
            cancellation of any insurance relative to the Project for any reason
            including non payment of premium;

      (ii)  at least 60 days (or such lesser period as may be agreed between the
            Agent, the Insurance Adviser and the Borrower Provided that such
            lesser period shall be a minimum of 30 days) before any reduction in
            any limit or coverage, any increase in any deductible or any
            termination before the original expiry date is to take effect;

      (iii) of any act or omission or of any event of which the insurer has
            knowledge and which might invalidate or render unenforceable in
            whole or in part any insurance relative to the Project.

(6)   In addition to any other requirements relating to such insurance, the
      Borrower shall ensure and agrees to procure that each of its primary
      insurers shall ensure in relation to

                                      103
<PAGE>

      each such policy of insurance that it acknowledges that the Borrower is
      the borrower under loans with the Lenders and that the following
      provisions shall apply to the policy:

      (i)   the insurer undertakes to advise the Lenders of any circumstance
            regarding the renewal or non-renewal of the insurance or failure to
            pay the premium so that there is not, under any circumstances, a
            break in the period of insurance and to pass outstanding premium
            notices to the Lenders, who may pay the premium on behalf of the
            insured;

      (ii)  the sums insured and risks covered under the insurances may not be
            reduced in any way without the prior written consent of the Agent;

      (iii) in the event of failure to pay the premium by the insured, as
            referred to in paragraph 5(i) above, the insurer undertakes to issue
            an endorsement modifying the policy, with effect from the preceding
            due date, to take account of any requirements of the Agent;

      (iv)  the insurer undertakes to make all payments under the policy
            directly into the Compensation Account and to name the Security
            Trustee as sole loss payee (except under policies or sections
            covering legal liability in respect of third party claims or
            employer's liability, or in respect of all payments following
            notification by the Security Trustee of the occurrence of a
            Designated Event or a Prepayment Event);

      (v)   the Insurers undertake to each Lender that the policy shall not be
            invalidated as regards the respective rights and interest of each
            Lender and that the Insurers will not seek directly or indirectly to
            avoid any liability under this policy because of any act, neglect,
            error or omission made by any other Insured (whether occurring
            before or after the inception of the policy), including, without
            limitation, any failure by any other Insured to disclose any
            material fact, circumstance or occurrence, any misrepresentation by
            any other Insured, any breach or non-fulfilment by any other insured
            whether or not any such act, neglect, error or omission, could, if
            known at any time, have affected any decision of the Insurers to
            grant the policy, to agree to any particular term or terms of the
            policy (including, without limitation, this provision) and the
            amount in relation to this policy or to liability which might arise
            thereunder. The Lenders shall have no duty of disclosure except in
            relation to information made available to them by any other insured
            parties relating to this Project,

      and that the foregoing provisions shall take effect from the date of the
      policy and may not be altered without the consent of the Lenders.

                     FORM OF BROKER'S LETTER OF UNDERTAKING

[To the Agent]

Dear Sirs,

We confirm, in our capacity as insurance brokers to Yorkshire Link Limited, that
the insurances (the "INSURANCES") specified in Part [2] [other than Professional
Indemnity insurance, which will be in effect on 15 April 1996] [3] of Schedule 8
to the facility agreement (the "FACILITY AGREEMENT") dated [ ] 1996 between
Yorkshire Link Limited as borrower, ABN AMRO Bank N.V. as arranger, issuing bank
and agent and the parties named therein as banks are in effect as at the date
hereof on and in respect of the risks set out in the attached cover notes. We
also confirm that the Insurers have acknowledged the Notice of Assignment of
Insurances (a copy of which is attached hereto) and that the relevant
endorsements required pursuant to Schedule 8 to the Facility Agreement have been
or will be issued in substantially the form set out in Part 3 of Schedule 8 in
respect of the insurance policies (the "POLICIES") evidenced in the attached
cover notes for the period stipulated therein. Terms defined in the Facility
Agreement shall have the same meaning in this letter.

We confirm that we will advise you if the Borrower fails at any time to pay any
premiums due in respect of the Insurances. We further confirm that, in our
opinion, such Insurances comply with the Schedule of Minimum Insurances set
forth in, and the other provisions of, Schedule 8 of the Facility Agreement.

Pursuant to instructions received from the Borrower, we hereby undertake in
respect of the interests of the Borrower and the Lenders in the insurances
referred to in the attached cover notes, binder or certificate from [the
Insurers/us] that we will use our best endeavours:

1.    to seek Insurers' agreement to have endorsed on each and every Policy as
      and when the same is issued endorsements substantially in the form
      attached hereto together with a copy of the said Notice of Assignment of
      Insurances to the insurer signed by authorised signatories of the Borrower
      and acknowledged by the Insurers;

2.    (a)   to advise you promptly upon receipt of notice of any material
            changes which we know to be material notified to us which are
            proposed to be made in the terms of the insurances and which, if
            effected, would result in any material reduction in limits of
            coverage (including those resulting from extensions) or in any
            increase in deductibles, exclusions or exceptions;

      (b)   to notify you at least 30 days prior to the expiry of these
            insurances if we have not received instructions from the Borrower to
            negotiate renewal, and, in the event of our receiving instructions
            to renew, to advise you promptly of the details thereof; and

                                      106
<PAGE>

      (c)   to notify you at least 30 days prior to ceasing to act as brokers to
            the Borrower (unless owing to circumstances beyond our control in
            which case we shall notify you promptly upon becoming aware that we
            shall cease, or that we have ceased, to act);

3.    to pay to the Facility Agent without any set-off or deduction of any kind
      for any reason any and all proceeds from the insurances received by us
      from the Insurers except as might be otherwise permitted in the relevant
      loss payable clauses set out in the attached endorsements;

4.    to advise you:

      (a)   if any insurer cancels or gives notice of cancellation of this
            insurance at least 30 days before such cancellation is to take
            effect (unless owing to circumstances beyond our control in which
            case we shall notify you promptly upon becoming aware of such
            cancellation or notice of cancellation); and

      (b)   of any act or omission or of any event of which we have actual
            knowledge and which will invalidate or render unenforceable in whole
            or in part this insurance;

5.    to disclose to the Insurers and the Agent any fact, change of circumstance
      or occurrence which we know to be material to the risks insured against
      under the insurances promptly when we become aware of such fact, change of
      circumstance or occurrence;

6.    to hold the insurance slips or contracts, the Policies with any renewals
      thereof of any new or substitute policies (in each case, issued only with
      the Agent's consent), to the extent held by us, to the order of the Agent.

The above undertakings are given:

      (a)   subject to our lien, if any, on the Policies referred to above for
            premiums and fees due under and in respect of the Policies and
            subject to any Insurers' right of cancellation (if any) following
            default in excess of 60 days in payment of such premiums, but we
            undertake to advise you as soon as practicable if any such amounts
            are not paid to us by the due date and to give you a reasonable
            opportunity of paying such amounts of such premiums outstanding
            before notification of cancellation on behalf of the Insurers; and

      (b)   subject to our continuing appointment as insurance brokers to the
            Borrower and shall automatically cease upon termination of our
            appointment.

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

                                Yours faithfully,
