                  accordance with Clause 6.3(d)(ii) only ("Excess Broken Funding
                  Costs");

                  Business Days of demand to that effect addressed by EIB to the
                  Borrower; or

            (iii) the issuer of such BF Letter of Credit shall have given notice
                  to EIB of the date of expiration thereof and less than fifteen
                  days remain until the date of expiry of such BF Letter of
                  Credit and EIB has not received a replacement BF Letter of
                  Credit of equivalent value issued in its favour in respect of
                  which more than three hundred days remain until the date of
                  expiry thereof,

            and in the case of (i) above the amount of such demand (which shall

            equal to the unpaid Excess Broken Funding Costs and in the case of
            (ii) and (iii) above the amount of such demand shall be equal to the
            Total Sum specified therein less any amount previously received by

            account and the amounts from time to time credited thereto shall be
            the subject of a first ranking security interest created in favour
            of EIB as security for the payment when due of Excess Broken Funding
            Costs and a second ranking security interest created as security for
            the performance when due of any obligation owed by the Borrower to

                  Prepayment Date in accordance with the Prepayment Notice,

            on successive Payment Dates following the Prepayment Date calculated
            as the amount by which (1) interest that would have been payable
            hereunder in respect of that period on the amount so prepaid exceeds
            (2) the interest which would have been payable during that period if
            calculated at the Reference Rate, discounted to the Prepayment Date
            by applying a discount rate equal to the Reference Rate.

      (d)   COMPENSATION IN RESPECT OF COMPULSORY PREPAYMENTS:

            In the case of a Compulsory Prepayment, the Borrower shall pay to

                  incurred by EIB in respect of the relevant prepaid amount for
                  each period ending on successive Payment Dates following the
                  Prepayment Date calculated as the amount by which (1) interest
                  that would have been payable hereunder in respect of that
                  period on the amount so prepaid exceeds (2) the interest which
                  would have been payable during that period if calculated at
                  the Reference Rate, discounted to the Prepayment Date by
                  applying a discount rate equal to the Reference Rate; and

            (ii)  an amount in Sterling calculated at the annual rate of 0.25
                  per cent from the Prepayment Date to the respective dates on
                  which each instalment of the amount prepaid would have been
                  repayable but for the prepayment.

6.4   CASH COLLATERAL IN LIEU OF PREPAYMENT

      (a)   Whenever the Borrower makes a Voluntary Prepayment or a Compulsory
            Prepayment and, but for the operation of this Clause 6.4, the
            Borrower would be required to pay compensation calculated in
            accordance with Clause 6.3(c) or (d), the Borrower may request, by
            written notice thereof to EIB, (a "Cash

                                       15
<PAGE>

            Collateralisation Request") that the amount to be prepaid be
            credited to the EIB/Borrower Prepayment Cash Collateral Account.

      (b)   Provided that the terms of the EIB Cash Security arising from such
            cash collateralisation are acceptable to EIB (acting reasonably),
            EIB shall accede to a Cash Collateralisation Request and the amount
            so requested to be paid to the EIB/Borrower Prepayment Cash
            Collateral Account shall be so paid to such account. EIB shall be
            entitled to regard the terms of such EIB Cash Security to be
            unacceptable to it in the circumstances (inter alia) where EIB has
            been advised by suitably qualified and experienced legal counsel
            that, by reason of matters then prevailing, the validity and
            enforceability of such EIB Cash Security would be in question.

      (c)   EIB shall be entitled to apply the whole or any part of the amount
            from time to time in whole or partial prepayment of the Loan at any
            time following the taking of any action by or on behalf of the Banks
            pursuant to clause 22 of the Commercial Banks Facility Agreement or
            (where no compensation under Clause 6.3(c) or, as the case may be,
            Clause 6.3(d) would be payable by reason of such prepayment) at any
            time after the occurrence of an Event of Default and such prepayment
            shall be deemed for all purposes to be a Voluntary Prepayment or, as
            the case may be, a Compulsory Prepayment in respect of which
            compensation shall be payable by the Borrower to EIB calculated in
            accordance with Clause 6.3(c) or, as the case may be, Clause 6.3(d).
            The exercise of rights by EIB under this Clause 6.4(c) shall take
            precedence over any exercise by the Borrower of its rights under
            Clause 6.4(d).

      (d)   The Borrower may at any time by giving a Prepayment Notice pursuant
            to Clause 6.2(a) require that the whole or any part of the amount
            from time to time standing to the credit of the EIB/Borrower
            Prepayment Cash Collateral Account be applied in whole or partial
            prepayment of the Loan, in which event the provisions of Clause 6.2
            shall apply and the Borrower shall pay to EIB compensation
            calculated in accordance with Clause 6.3(c).

6.5   REDUCTION OF EIB BANK SECURITY

      (a)   The Borrower may (subject to Clause 6.6(g)), at the same time as any
            prepayment of all or any part of any semi annual instalment of the
            Loan pursuant to either of Clause 6.2 or 6.3 or any cash
            collateralisation made in lieu of a prepayment pursuant to Clause
            6.4, request that EIB deliver to the Issuing Bank a notice in the

6.6   GENERAL PROVISIONS REGARDING PREPAYMENT

      (a)   In the case of Voluntary Prepayments any amount prepaid shall be

            rata basis.

      (b)   Save as provided in Clause 6.4(c), any amount prepaid upon a
            Compulsory Prepayment shall be applied to reduce the repayment
            instalments of the Loan in inverse order of their due dates for
            payment.

      (c)   Each prepayment shall be accompanied by payment to EIB of accrued
            interest and early repayment compensation calculated on the amount
            prepaid in accordance with Clause 6.3(c) and 6.3(d).

      (d)   For the purpose of determining compensation payable for the
            prepayment of the Unguaranteed Loan under Clause 6.3(c) and
            6.3(d)(i):

            (i)   the interest rate applicable to the Unguaranteed Loan is the
                  Interest Differentiated Rate;

            (ii)  for the purpose of calculating the Reference Rate the
                  Reference Rate shall be increased by a number of basis points
                  equal to the difference between the Interest Rate and the
                  Interest Differentiated Rate.

      (e)   Amounts prepaid may not be redrawn.

      (f)   This Clause 6 shall not prejudice Clause 9 or 10.

      (g)   Each prepayment pursuant to either Clause 6.2 or 6.3 or any cash
            collateralisation made in lieu of a prepayment pursuant to clause
            6.4 shall be applied as between the Loan guaranteed by a Letter of
            Credit, the Loan guaranteed by the EIF Senior Guarantee and the
            Unguaranteed Loan pro rata in the proportion which each of the Loan
            guaranteed by a Letter of Credit, the Loan guaranteed by the EIF
            Senior Guarantee and the Unguaranteed Loan bears to the Loan.

            represents such a percentage of the entire sum outstanding in
            respect of the Loan as corresponds to the Percentage Participation
            in the Relevant EIB Bank Security of the Issuer in relation to which

            45-day grace periods referred to in Clause 9.1 and the foregoing

            of the Letter of Credit, the EIF Guarantee or other Relevant EIB
            Security, result in EIB not being able to make a claim under any
            Letter of Credit or the EIF Guarantee or to realise any other
            relevant EIB Security in relation to any sum demanded by EIB by at
            least three Business Days prior to the Expiry Date of such Letter of

            shortened to such extent as may be necessary so as to enable EIB to
            make such a claim prior to such Expiry Date.

      (a)   to the effect that the Loan will be prepaid in whole or in part and,
            if in part, to an extent equivalent to the proportion thereof in
            respect of which non payment when due by the Borrower would give
            rise to an obligation on the part of such Issuer to make payment
            under the Relevant EIB Bank Security; and/or

      (b)   that steps will be taken by the Borrower (whether by way of Letters
            of Credit or the provision of EIB Cash Security (on terms acceptable
            to EIB, acting reasonably) by the Borrower or the Issuer by payment
            to the appropriate EIB Cash Collateral Accounts) to ensure that
            there is provided to EIB such EIB Bank Security as will have an EIB
            Security Value at least equal to the EIB Security Value of the
            Letter of Credit to be replaced;

      Clause 9.1(e).

9.4   REPLACEMENT OF EIF

      If EIF is required to be replaced pursuant to Clause 9.1(f), the Borrower

      (b)   that steps will be taken by the Borrower to ensure that there is
            provided to EIB such EIB Security as will have a value at least
            equal to the EIF Senior Guarantee;

      and will procure implementation of such steps (with such modifications

      (a)   NON-PAYMENT BY BORROWER: failure by the Borrower to pay any sum that
            is due on the Loan (other than a sum the non-payment of which gives

            the EIF Senior Guarantee or out of the proceeds of realisation of
            any other Relevant EIB Security other than EIB Security provided
            pursuant to Clause 8.5(b)) within two London Business Days of the
            due date;

      (b)   MISREPRESENTATION: any representation, warranty or statement made by
            the Borrower in Clause 4.1 of the Amendment and Restatement
            Agreement or clause 20 of the Commercial Banks Facility Agreement
            (as deemed to be repeated on the dates set out in clause 20 of the

            with Clause 9.5) or the EIF Senior Guarantee Facility Agreement;

      (e)   DEFAULT RATIOS: as evidenced by any Project Forecast prepared
            pursuant to clause 19 of the Intercreditor Agreement:

            (i)   the EIB Loan Life Cover Ratio on the date as at which such
                  Project Forecast was prepared is less than 1.10:1; or

            (ii)  the average of the EIB Forecast Annual Debt Service Cover
                  Ratios in respect of the two 12 months periods within each
                  consecutive period of 24 months, of which the first commences
                  on the date as at which the relevant Project Forecast has been
                  prepared and the last ends on the CBFA Final Maturity Date
                  (and for the purposes of this clause each subsequent period of
                  24 months shall commence on the day after the last day of the
                  proceeding period of 24 months), is less than 1.05: 1.

      (a)   If any of the events described in Clause 10.1 shall occur, EIB may
            (in accordance with part 13 of the Intercreditor Agreement) demand
            immediate payment by the Borrower of such part of the Loan the
            non-payment of which by the Borrower would not give rise to a right
            exercisable by EIB to make a claim for the payment to it of an equal
            amount under any Letter of Credit or the EIF Senior Guarantee or out
            of the proceeds of realisation of any other Relevant EIB Security
            other than EIB Security provided pursuant to Clause 8.5(b).

      (b)   Upon any demand for payment being made by EIB pursuant to Clause

                  where appropriate, instruct the Security Trustee to enforce,
                  the EIB Security to such extent as EIB shall decide; and

            (iii) EB may exercise such rights as are then available to it under
                  the Intercreditor Agreement to require the Security Trustee to
                  exercise any and all such rights as may be available to it
                  under any of the Shared 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

                  (A)   it possesses a current AA rating or better (whether
                        graded plus or minus or otherwise qualified) awarded by
                        Standard & Poor's Corporation or a current Aa rating or

                        otherwise qualified) in respect of its most recent
                        unsecured (and unsubordinated) long or medium term issue
                        on any capital market or, if the said agencies should
                        both cease to publish such ratings, it possesses an
                        equivalent rating from another rating agency of equal
                        repute (the "CREDIT STANDARD"); or

                  (B)   it is otherwise approved by EIB,

                  and in each case its aggregate liability or proposed liability
                  under the EIB Bank Security does not and will not exceed any
                  specific limit notified by EIB to the Borrower prior to the
                  date the person in question becomes a party to the Commercial
                  Banks Facility Agreement as would cause the limit to be
                  exceeded in respect of the person in question; and

            (ii)  it is an institution which is permitted under the laws to
                  which it is subject in connection with its liabilities under

            that it is not approved or, being admitted to be a Qualifying Issuer
            by virtue only of Clause 11.3(a)(i)(B) or by virtue of EIB not
            giving such a notice of non approval, should be the subject of a
            notice by EIB to the Senior Facility Agent (with a copy to the
            Borrower) to the effect that the Issuer has, in the opinion of EIB,
            acting reasonably, suffered a material adverse change in its
            financial condition since its approval by EIB under that clause or,
            as the case may be, since ceasing to possess a rating of the Credit
            Standard, it shall cease to be a Qualifying Issuer.

                  of Default has occurred of which EIB has actual written notice
                  from the Borrower and EIB has certified that, in its opinion,
                  the event concerned would, if the release concerned were to
                  take effect, be materially prejudicial to the interests of EIB
                  (provided that, for the purpose of the Release Condition in
                  relation to the Second Release Date, no regard shall be had to

                  of the Intercreditor Agreement.

      (c)   From the date on which it believes the above conditions to be met,
            the Borrower may, 60 days prior to any relevant Release Date or any
            Payment Date occurring after the relevant Release Date, seek a
            release by requesting EIB to consider whether the Release Condition
            is fulfilled and, upon being satisfied that the Release Condition is
            fulfilled, to certify and, if not so satisfied, to inform the

                                       29
<PAGE>

            Borrower and the Senior Facility Agent accordingly. Within 30 days
            of receipt of each request, EIB shall examine each condition of the
            Release Condition and shall certify to the Borrower and the Senior
            Facility Agent whether or not the Release Condition is satisfied.

      (d)   The following provisions of this Clause 12 shall apply upon the
            delivery of EIB's certificate as aforesaid.

12.2  LETTER OF CREDIT REDUCTION SCHEDULE

      fulfilled, EIB shall deliver:

      (a)   a notice in the form of Appendix 3 to Annex 1 to the Issuing Bank
            (with a copy to the Borrower) specifying that the "Total Sum" (as
            defined in the Bank Letter of Credit) shall be reduced by an amount

            Notice of Release to be issued pursuant to paragraph (b) below) is
            to take account of the Adjusted Required Value of EIB Bank Security
            for the Loan arising from the satisfaction of the Release Condition
            and the operation of the definition of "Required Percentage" by
            reason thereof; and

      issue of the Completion Certificate; and

      "SECOND RELEASE DATE" means the date following six years after the date of
      issue of the Completion Certificate.

12.3  EFFECTIVE DATE OF RELEASE

      Upon the delivery of a Notice of Release, the release shall take effect
      upon the issue by the Account Bank (as defined in the Intercreditor
      Agreement) to EIB of a certificate, in form and substance satisfactory to
      EIB, to the effect that the conditions specified in Clause 12.1(b)(i) to
      (vi) is fulfilled as at the date of issue of such certificate.

      In order to give effect to the release of any other EIB Bank Security, EIB
      undertakes to execute and do all such deeds, acts and things as the

      reduce the value of such other EIB Bank Security to its Adjusted Required
      Value.

      (a)   If any deduction or withholding for or on account of Taxes or any
            other deduction from any payments made or to be made to EIB under
            any of the Finance Documents is required by law, then the Borrower

                  (including, but without prejudice to the generality of the
                  foregoing, the full amount of any deduction from any
                  additional amount paid pursuant to this Clause 14);

            (iii) indemnify EIB on demand against any losses or costs incurred

            (iv)  promptly pay to EIB an additional amount being the amount

                  by it had no such deduction or withholding or other deduction
                  been made.

      (b)   If any deduction or withholding for or on account of Taxes or any
            other deduction from any payments made or to be made by the Security
            Trustee to EIB under any of the Finance Documents is required by
            law, then the Borrower will promptly pay to EIB an additional amount

            received by EIB will equal the full amount which would have been
            received by it had no such deduction or withholding or other
            deduction been made.

      (c)   If the Borrower makes a payment pursuant to Clause 14.3(a) or (b)
            and EIB has, in its sole opinion, (acting in good faith) received or
            been granted a credit against, relief, remission or repayment of,
            any tax paid or payable (a "Tax Credit") which is identified by EIB
            as being attributable to that payment or the corresponding payment
            under the Finance Documents, EIB shall, to the extent that it can do
            so without prejudicing the retention of the tax benefit of such
            credit, relief, remission or repayment, promptly pay to the Borrower
            such amount as EIB reasonably determines to be attributable to such
            payment and which will leave EIB (after

                                       32
<PAGE>

            such payment) in no better or worse position than it would have been
            in had the relevant deduction or withholding not been required.

      (d)   Any such payment pursuant to Clause 14.3(c) shall in the absence of
            manifest error be prima facie evidence of the amount due to the
            Borrower hereunder.

      (e)   Nothing herein contained shall interfere with the right of EIB to
            arrange its tax affairs in whatever manner it thinks fit, and in
            particular, EIB shall be under no obligation to claim credit,
            relief, remission, repayment or other benefit from or against its
            tax liability in respect of the amount of such deduction in priority
            to any other similar claims, reliefs, credits or deductions
            available to it, nor shall EIB be under any obligation to disclose

      the M62 with the construction of two tunnels (90m and 160m long
      respectively)

-     the widening of l.lkm of the existing D3M M1 motorway by the addition of
      two ancillary lanes

-     the construction on a new alignment of 15.8km of D3M standard between the
      MI at Belle Isle and the Al at Hook Moor, including a 1.3km diversion at
      Belle Isle interchange

-     the widening of the Al to 3 or 4 lanes in each direction between Hook Moor
      and Bramham Crossroads, including links towards Micklefield and the A64
      (some 9.9km overall)

      the Lenders (acting reasonably and after consultation with the Borrower)
      specify to be necessary, be amended to comply with any generally accepted

      change in currency.

1.13  Any reference to "continue" in the context of an Event of Default or
      Potential Event of Default shall be construed as follows:

      (a)   so that where the underlying circumstances which caused that Event
            of Default or Potential Event of Default are incapable of remedy,
            that Event of Default or Potential Event of Default is continuing,
            unless and until it has been expressly waived and any conditions of
            such waiver have all been fulfilled to the satisfaction of the
            Lenders;

      (b)   so that in any other case, that Event of Default or Potential Event
            of Default is continuing unless and until it has been expressly
            waived (and any conditions of such waiver have all been fulfilled)
            to the satisfaction of the Lenders or the underlying circumstances
            which caused that Event of Default or Potential Event of Default
            have been remedied so that the resulting position is not different
            from what it would have been if such Event of Default or Potential
            Event of Default had not occurred; and

      (c)   so that, in the case of the late delivery of a document which is
            subsequently satisfactorily delivered, or the withdrawal or
            settlement of a claim the existence or

                                       10

            pursuance of which constituted an Event of Default or Potential
            Event of Default, that Event of Default or Potential Event of
            Default is not continuing once the underlying circumstances no
            longer apply.

2.    THE FACILITY

      GRANT OF THE FACILITY: Pursuant to the terms of this Agreement prior to
      the Amendment Date, the person who was then the Lender granted to the
      Borrower, upon the terms and subject to the conditions hereof, the Loan
      Facility, in the aggregate principal amount of (pound)10,000,000.

2.1   NO RESPONSIBILITY: No Lender shall be obliged to concern itself with the
      application of amounts raised by the Borrower hereunder.

2.2   BORROWER'S OBLIGATIONS: For the avoidance of doubt, the obligations of the
      Borrower under this Agreement are in no way conditional upon the
      performance or observance of the terms of any of the Construction
      Contract, the DBFO Contract or any other Project Document or any provision
      thereof respectively by any party thereto and will not be affected or
      discharged by any matter affecting any of the Construction Contract, the
      DBFO Contract or any other Project Document including, without limitation,
      its performance, non-performance, frustration or invalidity or the
      destruction, non-completion or non-functioning of any of the goods and
      services to be supplied thereunder.

3.    INTEREST

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

3.2   DURATION: The duration of each Interest Period relating to the Advance
      shall, save as otherwise provided herein, be such that such Interest
      Period begins on a Payment Date and ends on the day preceding the next
      Payment Date;

3.3   CALCULATION OF INTEREST: Subject to clause 4 (Alternative Interest Rates)
      and clause 18 (Default Interest, Indemnity and Release), the rate of
      interest applicable to the Advance during each Interest Period relating
      thereto (the "Normal Interest Rate") shall be the rate per annum which is
      the higher of:

      (a)   LIBOR for that Interest Period on the Quotation Date therefor plus
            the Additional Costs Rate plus the Applicable Margin; and

      (b)   6%.

3.4   PAYMENT OF INTEREST: Subject to clause 3.5 (Deferral of Payments), on each
      Interest Payment Date, the Borrower shall pay to the Lenders accrued
      interest on each Advance to which such Interest Period relates.

                                       11

<PAGE>

3.5   DEFERRAL OF PAYMENTS:

      (a)   Any interest which would otherwise have been payable on an Interest
            Payment Date, shall be deferred (such interest being referred to in
            this Agreement as "Deferred Interest") in the circumstances set out
            in this clause 3.5 (Deferral of Payments).

      (b)   Interest accrued in the first two Interest Periods shall be
            deferred, subject to clause 3.5(c), until the third Interest Payment
            Date.

      (c)   The Borrower is entitled to continue to defer payments of interest
            and to defer payments of principal and Supplemental Interest on the
            third and any subsequent Interest Payment Date if (but only to the
            extent that) the Borrower is not entitled to make such payment of
            interest or principal or Supplemental Interest on that date by
            reason of the operation of clause 12.6 of the Intercreditor
            Agreement.

      (d)   The deferral of interest, principal or Supplemental Interest under
            this clause 3.5 shall be treated as an agreed variation of the
            original due dates and shall not constitute a breach of this
            Agreement or an Event of Default.

3.6   PAYMENT OF DEFERRED INTEREST: Deferred Interest shall be paid by the
      Borrower to the Lenders on the earlier of:

      (a)   the first Interest Payment Date on which the Borrower's entitlement
            to defer payment of interest under clause 3.5 has ceased to the
            extent that the Borrower then has cash available to pay such
            Deferred Interest in accordance with the cascade set out in clause
            12.3 of the Intercreditor Agreement;

      (b)   the declaration of an Event of Default by the Lenders under clause
            17 (Events of Default) at any time after such declaration is
            permitted by the terms of the Intercreditor Agreement;

      (c)   the Final Repayment Date;

      (d)   prepayment in full of the Facilities; or

      (e)   the date of termination or expiry of the DBFO Contract.

3.7   INTEREST ACCRUING ON DEFERRED INTEREST:

      (a)   Deferred Interest accrued in any Interest Period shall itself bear
            interest during any subsequent Interest Period whilst it remains
            unpaid at the Normal Interest Rate applicable during such period.

      (b)   At the end of each Interest Period, interest which has accrued on
            the Deferred interest which is not paid on that date shall be added
            to and treated as forming part of the Deferred Interest and interest
            shall accrue thereon in accordance with clause 3.7(a).

4.    ALTERNATIVE INTEREST RATES

4.1   MARKET DISRUPTION if:

      (a)   LIBOR cannot be determined as contemplated in paragraph (a) of the
            definition in clause 1.1 (Definitions) and the Lenders determine
            that at or about 11.00 am (London time) on the Quotation Date for an
            Interest Period none or only one of the Reference Banks was offering
            to prime banks in the London Interbank Market sterling deposits in
            the amount and for the period required for the purposes of clause
            3.3 (Calculation of Interest); or

      (b)   before the close of business in London on the first day of an
            Interest Period the Lenders determine 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 3 (Interest) (and until any
      substitute basis for determining rates of interest has been agreed in
      accordance with the terms of clause 4.2 (Substitute basis) in respect of
      the event which caused this clause 4 to apply in respect of a particular
      Interest Period or, as the case may be, the Advance):

            (i)   (if clause 4.1(a) applies) the duration of the relevant
                  Interest Period shall be one month or such lesser duration as
                  shall cause it to end on the next Repayment Date; and

            (ii)  (if clause 4.1(a) or (b) applies) during such Interest Period
                  the rate of interest applicable to the Advance shall be the
                  rate per annum which is the sum of the Applicable Margin, the
                  Additional Costs Rate in respect thereof at such time and the
                  percentage rate per annum of the cost to the Lenders of
                  funding the Advance from the London Interbank Market (or, if
                  more practicable, from whatever other sources and in whatever
                  manner it may reasonably select) during such Interest Period.

4.2   SUBSTITUTE BASIS OR REPAYMENT: If either of those events mentioned at
      clauses 4.1(a) and (b) (Market Disruption) occurs:

      (a)   the Lenders shall promptly notify the Borrower of such event;

      (b)   within five days of such notification the Lenders and the Borrower
            shall enter into negotiations in good faith with a view to agreeing
            a substitute basis:

            (i)   for determining the rates of interest from time to time
                  applicable to the Advance; and/or

            (ii)  upon which the Advance 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.

      REPAYMENT: The Borrower shall repay the Advance by instalments on each
      Repayment Date in the amount set out opposite such Repayment Date below

      Provided that if on any Repayment Date the Borrower would be entitled to
      defer the payment of principal by reason of the provisions of clause
      3.5(c) (Deferral of Payments), then the Borrower shall defer the repayment
      of principal under this clause 5 until the earlier of:

      (a)   the first Repayment Date thereafter on which the Borrower's
            entitlement to defer principal under clause 3.5(c) has ceased to the
            extent that the Borrower then has cash available to pay such
            deferred principal in accordance with the cascade set out in clause
            12.3 of the Intercreditor Agreement;

      (c)   the Final Repayment Date;

      (d)   prepayment in full of the Facilities; and

      (e)   the date of termination or expiry of the DBFO Contract.

      For the avoidance of doubt, deferred principal shall continue to accrue
      interest in accordance with clause 3.4 (Payment of Interest).

6.    [UNUSED]

7.    ILLEGALITY

7.1   FUNDING OF ADVANCE: 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 Lender to make, fund or allow to remain outstanding any
      part of the Advance made or to be made hereunder, then if such Lender so
      requires, the Borrower shall within the period necessary to comply with
      the law, repay the relevant Lender's share of the Loan together with
      accrued interest thereon.

8.    PREPAYMENT

8.1   VOLUNTARY PREPAYMENT: The Borrower may, if it has given to the Lenders not
      less than ten business days' prior notice to that effect repay the whole
      or any part of the Advance (being an amount or integral multiple of
      (pound)1,000,000) (but so that if any repayment is made otherwise than on
      the last day of an Interest Period for the Advance, the Borrower shall pay
      broken Interest Period costs in accordance with clause 18.4 (Broken
      Periods) on the date of such prepayment).

8.2   NO REBORROWING: The Borrower shall not repay all or any part of the Loan
      except at the times and in the manner expressly provided herein and shall
      not, be entitled to reborrow any amount repaid or prepaid by it hereunder.

9.    TAXES

9.1   TAX GROSS-UP: Subject to clause 9.6, 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 required on account of any Relevant Tax to make any deduction
      or withholding from any sum payable by it to a Lender hereunder or if a
      Lender 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:

                                       15

<PAGE>

            (i)   the Borrower shall notify the relevant Lender 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
                  relevant Lender will forthwith notify the Borrower of its
                  liability to such Relevant Tax as soon as it becomes aware of
                  such liability;

            (ii)  the Borrower or the relevant Lender (as the case may be) shall
                  pay any such Relevant 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, the relevant
                  Lender 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.

9.2   DELIVERY OF RECEIPT: The Borrower shall after it has made any payment of
      tax referred to in clause 9.1 (ii) (Tax gross-up) to the applicable
      authority use all reasonable endeavours to deliver to the relevant Lender
      an original receipt (or a certified copy thereof) issued by such authority
      evidencing such payment as soon as possible.

9.3   INDEMNITY: Without prejudice to the provisions of clause 9.1 (Tax
      gross-up) but subject to clause 9.7, 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, a Lender is required
      by any law or regulation to make any payment, whether on account of tax
      (other than tax or 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 the relevant Lender hereunder, or any liability in respect of any such
      payment is asserted, imposed, levied or assessed against a Lender, then
      the Borrower shall upon demand, pay to the relevant Lender for its own
      account an amount sufficient to indemnify that Lender 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 the relevant Lender
      for any penalty incurred by the relevant Lender by reason of the relevant
      Lender failing to make timely payment of tax to the relevant authorities
      in circumstances where the relevant Lender had itself received an amount
      equal to such tax from the Borrower prior to the due date for payment
      thereof to such authorities. If a Lender makes any payment of tax referred
      to in clause 9.1(ii) (Tax gross-up) or this clause 9.3 (Indemnity) it
      shall promptly on receipt thereof use all reasonable endeavours to deliver

9.4   NOTIFICATION: If a Lender intends to make a claim pursuant to clause 9.3
      (Indemnity), it shall notify the Borrower of the event by reason of which
      it is entitled to do so and provide it with supporting evidence where
      practicable.

9.5   RELEVANT TAX: For the purposes of this clause 9 (Taxes) "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.

9.6   EXCEPTION TO GROSS-UP: If on the date that a payment becomes due hereunder
      to or for the account of a recipient:

      (i)   the relevant Lender is a Treaty Lender (as defined in clause 9.13)
            and the Treaty Lender did not comply with Clause 9.12 below; or

      (ii)  the relevant Lender is not a Qualifying Lender or, at any time on or
            after the date hereof but prior to such payment becoming due, the
            relevant Lender 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 the relevant Lender under clause 9.1 except as
      provided in clause 9.8.

9.7   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 Lender is not a Qualifying Lender or, at any
            time on or after the date hereof but prior to that date, the
            relevant Lender was not or ceased to be a Qualifying Lender; and

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

      any liability of the Borrower to indemnify the relevant Lender pursuant to
      clause 9.3 shall be correspondingly reduced except as provided in clause
      9.8.

9.8   CONDITIONS TO EXCEPTIONS: Clauses 9.6 and 9.7 shall not relieve the
      Borrower from making payments or increased payments under clauses 9.1 or
      9.3 if:

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

      (ii)  the Borrower would be obliged to make a payment or increased payment
            under clause 9.1 or 9.3 irrespective of whether the relevant Lender
            is at any time on or after the date hereof a Qualifying Lender.

9.9   TAX WARRANTY: To the extent that it is not at any time on or after the
      date hereof a Qualifying Lender within paragraph (a), (b) or (c) of the
      definition of "Qualifying

                                       17

<PAGE>

      Lender" in clause 9.13 below, each Lender warrants that it is, and will
      continue to be, a Qualifying Lender within paragraph (d) of that
      definition. Each Lender agrees to indemnify the Borrower, on demand and on
      an after-tax basis, against any tax, losses or other liabilities, together
      with any interest, penalties and expenses payable in connection therewith,
      which the Borrower incurs as a result of a breach of the warranty given by
      the relevant Lender in this clause 9.9.

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

9.11  TREATY LENDER: A Treaty Lender and the Borrower which makes a payment to
      which that Treaty Lender is entitled shall each co-operate 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.

9.12  TAX CREDIT: If the Borrower pays any additional amount under clause
      9.1(iii) or 9.3 (a "TAX PAYMENT") and the relevant Lender 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 relevant Lender is
      able to identify the Tax Credit as being attributable in whole or in part
      to the Tax Payment, then the relevant Lender shall reimburse to the
      Borrower such amount as it shall determine to be the proportion of the Tax
      Credit as will leave the relevant Lender, after that reimbursement, in no
      better or worse position than it would have been in if the Tax Payment had
      not been required. The relevant Lender 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. The relevant Lender shall
      not be obliged to disclose any information regarding its tax affairs or
      computations to the Borrower. Nothing in this clause 9.12 shall interfere
      with the right of the relevant Lender to arrange its tax affairs in
      whatever manner it thinks fit.

            (i)   a Lender incurs a cost (other than tax, or an increase in tax,
                  on its overall net income) as a result of its having entered

      thereof and, in consultation with the Borrower, the Borrower and the
      relevant Lender shall make reasonable efforts to mitigate the effects of
      such circumstances including the transfer of the relevant Lender's rights

<PAGE>

      Borrower notifies the Lenders that there have been one or more changes in

            (ii)  sufficient information, in such detail and format as may be

12.   PROJECT BUDGETS

12.1  DELIVERY OF PROJECT BUDGETS: No later than 60 days before the end of each

      such financial year as set out in the most recent Project Forecast
      delivered pursuant to clause 19 of the Intercreditor Agreement for the
      financial year in relation to which such budget was delivered, the Lenders
      (having consulted with the Technical Adviser and the Traffic Adviser) may
      require a change to any such budget within 30 days of receipt thereof, the

      and the Borrower shall prepare a revised budget reflecting such required
      change which shall then become the Project Budget for the Borrower's next

      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 relevant Lender would
      have been payable to that Lender on the last day of that Interest Period

      each Lender against any liabilities, costs, claims and expenses resulting
      from any failure to pay or any delay in paying such tax, provided that the
      Borrower shall not be required to pay any amount to compensate any person
      for any

                                       40

      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 has itself received (for value at least 7 business days prior
      to the due date for payment thereof) an amount hereunder from the Borrower
      sufficient to enable it to pay the same prior to such due date, provided
      that this clause 23.3 shall not extend to any stamp duty, registration and
      other documentation taxes arising from an assignment or transfer under
      clause 24.3 (Assignment by Lender) or clause 24.5 (Transfer by Lender).

24.   BENEFIT OF AGREEMENT

24.1  BINDING EFFECT: This Agreement shall be binding upon and enure to the
      benefit of each party hereto and its successors and assigns.

24.2  ASSIGNMENT BY BORROWER: The Borrower shall not, except with the prior
      consent of the Lenders assign or transfer all or any of its rights,
      benefits and obligations hereunder.

24.3  ASSIGNMENT BY LENDERS: A Lender may assign at any time at no cost to the
      Borrower, to any Affiliate acting through a UK Lending Office and (subject
      to clause 24.10) with the consent of the Borrower and the other Lender
      (such consent not to be unreasonably withheld or delayed and, in any
      event, such consent or refusal to be granted or refused within ten days of
      the proposed assignment) to any one or more entities all or any part (but
      if in part in a minimum amount of (pound)2,000,000) of the Lender's rights
      and benefits hereunder in respect of the Advance and in that event this
      Agreement and the other Finance Documents shall thereafter be read and
      construed and shall have effect as if the assignee were the relevant
      Lender to the intent that the assignee shall have the same rights against
      the Borrower hereunder as it would have had if it had been a party hereto.

24.4  ASSIGNEES: Unless and until an assignee has agreed with the relevant
      Lender that it shall be under the same obligations towards it as it would
      have been under if it had been a party hereto, no Finance Party shall be
      obliged to recognise such assignee as having the rights against it which
      such assignee would have had if it had been a party hereto.

24.5  TRANSFER BY LENDER: In addition to its rights under clause 24.3 and
      subject to clause 24.10, each Lender may at any time at no cost to the
      Borrower and the other Lender, with the consent of the Borrower (such
      consent not to be unreasonably withheld or delayed and, in any event, such
      consent or refusal to be granted or refused within ten days of the
      proposed transfer) transfer in accordance with this clause 24.5 to any one
      or more entities acting through a UK Lending Office all or any of its
      rights, benefits and obligations hereunder, in which case such transfer
      may be effected by the delivery to the relevant Lender of a duly completed
      and duly executed Transfer Certificate and payment of a fee of (pound)500
      by the proposed transferee whereupon:

      (a)   to the extent that in such Transfer Certificate the relevant Lender
            seeks to transfer its rights, benefits and/or its obligations
            hereunder as a Lender, the Borrower, the relevant Lender and the
            other Lender(s) shall each be released from further obligations to
            the other hereunder and their respective rights and benefits against

                                       41

<PAGE>

            each other hereunder shall be cancelled (such rights, benefits and
            obligations being referred to in this clause as "discharged rights
            and obligations");

      (b)   the Borrower, the remaining Lender(s) 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 obligations only insofar as the Borrower and
            such transferee have assumed and/or acquired the same in place of
            the Borrower and the transfering Lender; and

      (c)   such transferee shall become a party hereto as a Lender.

24.6  AMOUNT OF TRANSFER: Any transfer pursuant to clause 24.5 (Transfer by
      Lenders) shall be either such that the aggregate amount of the
      Outstandings thereby transferred is not less than (pound)2,000,000 or such
      that such transfer comprises all of the Outstandings of the relevant
      Lender.

24.7  PARTIAL ASSIGNMENT OR TRANSFER: In the case of a partial assignment or
      transfer:

      (a)   the relevant Lender shall exercise the powers of an agent lender for
            the purposes of this Agreement and, in relation to the Borrower,
            exercise all discretions and rights reserved to that Lender under
            this Agreement; and

      (b)   all payments due to the relevant Lender under this Agreement shall
            be deemed to be payable to that Lender and each assignee or
            transferee Lender in proportion to their participations.

24.8  FURTHER ASSURANCE: The Borrower shall agree:

      (a)   to make such amendments to any Finance Documents as the Lenders may
            require to reflect such transfer; and

      (b)   to carry out such further acts in connection with such assignment or
            transfer as may reasonably be required by the Lenders to effect any
            assignment or transfer in accordance with this clause 24.

24.9  DISCLOSURE OF INFORMATION: The Lenders may disclose to a potential
      assignee or transferee or to any other person who may otherwise enter into
      contractual relations with it in relation to this Agreement a copy of this
      Agreement and such of the information supplied to the Lenders pursuant to
      or in connection with this Agreement as the Lenders shall consider
      appropriate having regard to the terms of the Confidentiality Agreement
      set out in the Sixth Schedule.

24.10 RIGHTS OF PRE-EMPTION: If a Lender proposes to transfer any of its rights
      and benefits under this Agreement (other than a transfer to an Affiliate
      under clause 24.3) it shall first give to the other Lender(s) notice (a
      TRANSFER NOTICE) of the proposed transfer, together with details of the
      amount to be transferred, the purchase price and any other material terms
      of the transfer. The continuing Lender(s) shall have the right to purchase
      the rights and benefits outlined in the Transfer Notice, on the same terms
      as specified therein. If

                                       42

<PAGE>

      there are more than one continuing Lenders then the continuing Lenders
      shall have the right to purchase an amount equal to the proportion that
      their Advances bear to the total of all Advances not held by the
      transferring Lender. If the continuing Lender(s) shall not have exercised
      their rights within 15 business days of the issue of the Transfer Notice,
      they shall be deemed to have elected not to purchase, provided that, if
      there are more than one continuing Lenders and some of the continuing
      Lenders have elected not to purchase then the other continuing Lenders
      shall have a further 5 business days to elect to purchase that proportion.

25.   PARTIAL INVALIDITY, WAIVER AND AMENDMENTS

25.1  ILLEGALITY: If at any time any provision hereof is or becomes illegal,
      invalid or unenforceable in any respect under the law of any jurisdiction,
      neither the legality, validity or enforceability of the remaining
      provisions hereof nor the legality, validity or enforceability of such
      provision under the law of any other jurisdiction shall in any way be
      affected or impaired thereby.

25.2  NO WAIVER: No delay or omission by any party hereto in exercising any of
      its rights hereunder shall operate or be construed as a waiver thereof nor
      shall a single or partial exercise of any such right preclude any other or
      further exercise thereof or the exercise of any other right of such party
      hereunder.

25.3  AMENDMENTS: Any term hereof may only be amended in writing.

26.   NOTICES

      fax or international courier service (but so that, so far as utilisation
      requests are concerned, the Lenders will only act upon receipt of the
      original document).

      party to another pursuant hereto shall be in the English language.

                        BANK OF ENGLAND: MONETARY CONTROL

                         ADDITIONAL COSTS' RATE FORMULA

1.    The additional rate relative to the Loan is, subject as hereinafter
      provided, the percentage rate arrived at by applying the following
      formula:

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

      Where:

      B  =  The percentage of the Lender's eligible liabilities then required
            to be held on a non-interest-bearing deposit account with the Bank
            of England.

      Y  =  The rate at which sterling deposits in an amount comparable to the
            amount of the Loan are offered by the relevant Lender to leading
            banks in the London Interbank Market at or about 11.00 a.m. on the
            commencement of the relevant Interest Period for a period comparable
            to the Interest Period.

      L  =  The average percentage of eligible liabilities which the Bank of
            England from time to time requires the relevant Lender to maintain
            as secured money with members of the London Discount Market
            Association and/or as secured call money with those money brokers
            and gilt-edged market-makers recognised by the Bank of England.

      X  =  The rate at which secured sterling deposits in an amount
            comparable to the amount of the Loan may be placed by the relevant
            Lender with members of the London Discount Market Association and/or
            as secured call money with money brokers and gilt-edged
            market-markers at or about 11.00 a.m. on the commencement of the
            relevant Interest Period for a period comparable to the Interest
            Period.

      S  =  The percentage of the relevant Lender's eligible liabilities then
            required to be placed as a special deposit with the Bank of England.

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

      For the purposes of this paragraph "ELIGIBLE LIABILITIES" and "SPECIAL
      DEPOSITS" shall bear the meanings ascribed to them from time to time by
      the Bank of England.

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

<PAGE>

3.    The additional rate computed by the relevant Lender in accordance with
      this Schedule shall, if not already such a multiple, be rounded upwards to
      the nearest whole multiple of one-sixteenth of one per cent (1/16) per
      annum.

4.    The calculation of the additional rate for the Loan will be made by the
      relevant Lender on the commencement of the relevant Interest Period
      relative thereto.

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

6.    A negative result obtained by subtracting X from Y or Z from Y shall be
      taken as zero.

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

8.    The percentages used in B, L and S above shall be those required to be
      maintained on the first day of the relevant period as determined in
      accordance with Y above.

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

10.   The determination of the Additional Costs Rate in relation to any period
      shall, in the absence of manifest error, be conclusive and binding on all
      of the parties hereto.

11.   The relevant Lender may from time to time, after consultation with the
      Borrower, determine and notify to all the parties hereto any amendments or
      variations which are required to be made to the formula set out above in
      order to comply with any requirements from time to time imposed by the
      Bank of England in relation to the Advance denominated in sterling
      (including any requirements relating to sterling primary liquidity) and,
      any such determination shall, in the absence of manifest error, be
      conclusive and binding on all the parties hereto.

Dear Sirs

We refer to the Facility Agreement dated [ ], made between us. Capitalised terms
used and not otherwise defined herein shall have the meanings given to them in
that Facility Agreement.

1.    We, [ ], in our capacity as Lender hereby agree that (save as provided in
      paragraph 2 below) we shall keep confidential and not disclose to any
      third person or make use of for purposes unconnected with the Finance
      Documents the following:

      (b)   any confidential or proprietary information (including documents,
            computer records, specifications, formulae, evaluations, methods,
            processes, technical descriptions, reports and other data, records,

            or the Traffic Data (each as defined in the DBFO Contract)) provided
            to or arising or acquired by YLL pursuant to the terms or
            performance of the DBFO Contract (including without limitation any
            such documents or information supplied in the course of proceedings
            under the Disputes Resolution Procedure (as defined in the DBFO
            Contract)); and

      (c)   all of the information, reports or documents supplied in or in
            connection with the invitation to tender for the DBFO Contract, any

            discussions thereto or any calculations made or conclusions or
            determinations reached in accordance with the Finance Documents
            (including the Financial Model and any results obtained from it);

      together, the "Confidential Information".

2.    We shall be entitled to disclose any Confidential Information (subject to
      any restrictions to the contrary imposed by a person other than YLL in
      relation to information which is confidential to them):

      (a)   with the prior written consent of YLL;

<PAGE>

      (b)   to any other Lender (as defined in the Intercreditor Agreement);

      (c)   when required to do so by any law, regulation or official
            requirement;

      (d)   to our professional advisers and consultants who need to know such
            and upon obtaining from them in favour of ourselves a similar
            confidentiality undertaking and providing a copy of such to the
            Borrower;

      (e)   to the extent that the same has become generally available to the

            an obligation of confidentiality to another person; and

      (f)   to any person proposing to become a Lender in accordance with the
            terms of the Facility Agreement upon obtaining from them in favour
            of YLL a similar confidentiality undertaking and providing a copy of
            such to YLL.

3.    If we are or any person to whom we disclose Confidential Information in
      accordance with this undertaking is legally compelled by a court of
      competent jurisdiction or by a supervisory or regulatory body to disclose
      any of the Confidential Information, we will use all reasonable efforts to
      the extent permitted by any relevant order to provide YLL with prompt
      notice thereof so that the Borrower may seek a protective order or other
      appropriate remedy. If the protective order or other remedy is not
      obtained, then we agree that, if requested by the Borrower, we will
      disclose only that portion of Confidential Information as we reasonably
      believe ourselves to be legally compelled so to disclose.

4.    Our obligations under this undertaking shall continue until the date
      falling on the fifth anniversary of the Termination Date (as defined in
      the DBFO Contract).

5.    This undertaking is to be governed by and construed in accordance with the
      laws of England.

Yours faithfully,
