                  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

      "FIRST RELEASE DATE" means the date following four years after the date of
      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

                  period for payment permitted by the applicable law such amount
                  as is required to be paid in consequence of the deduction
                  (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

                  additional amount not being paid on the due date for payment

            (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
            being the amount required to procure that the aggregate net 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)
