            enforceable against them or that such payment may not in itself
            result in any benefit to any of the Beneficiaries or may result in
            an Excluded Person being released from any obligation to make such
            payment AND so that payment shall be paid by the Trustees out of the
            Trust Fund or the income thereof but to the extent that any PAYE or

            written consent must be obtained from the Settlor.

26.   RECEIPTS FROM BENEFICIARIES

      Notwithstanding anything contained in this Settlement the Trustees may as
      a condition of conferring any benefit upon any of the Beneficiaries
      require that such Beneficiary provides a receipt in respect of the same or

      company, a subsidiary or a subsidiary of a holding company (all as defined

      solvent or insolvent) or winding-up or a receiver is appointed of the
      Settlor's assets or the Settlor is the subject of any take-over or merger

      Settlement and thereafter this Settlement to the Settlor shall continue
      and references in this Settlement to and all liabilities under this
      Settlement of the Settlor shall mean and devolve respectively upon the
      Substitute Settlor.

      The Trustees shall not be liable to provide benefits under or in
      connection with this Settlement which in aggregate exceed the value of the
      Trust Fund from time to time.

                                                                              16

<PAGE>

      respect of the eligibility of any person to become or remain a Beneficiary
      or Employee or an Excluded Person shall be conclusive in favour of the
      Trustees.

(2)   In particular any written statement signed by a person being or purporting

      and any Participating Company to the effect that any person is or has
      ceased to be a Beneficiary or Employee or as to any other circumstance
      affecting a person believed by the Trustees to be or not to be a
      Beneficiary or Employee may be treated by the Trustees as conclusive
      evidence of the matters referred to in the statement.

31.   COUNTERPARTS

      This Settlement may be executed in counterpart, each of which shall be an
      original but together shall constitute one and the same instrument.

      beneficial owner of the Trust Fund and their powers shall not be
      restricted by any principle of construction (or rule or requirement of the
      Proper Law save to the extent that such is obligatory) but shall operate
      according to the widest generality of which the foregoing words are
      capable notwithstanding that certain powers are hereinafter more
      particularly set forth SAVE that the Trustees shall have no power either
      acting singularly or jointly with any other person (i) to borrow money or
      other property on the security of the Trust Fund or unsecured with power

      deposit or transfer any such investments or property with or to any person
      firm or company on trust or by way of security.

2.    RESTRICTIONS ON INVESTMENT POWERS

      The Trustees shall be restricted in their powers of investment in the same
      way that an employee of the Settlor or of a Participating Company is
      restricted by regulatory constraints as shall be notified from time to
      time whether imposed by the employer generally or by any body the
      directions of which the employer adopts in respect of investments that may
      not be made by employees so that the Trustees shall follow that process
      which an employee is obliged to follow to ensure that restrictions on
      investment powers are not breached.

3.    POWERS OF INVESTMENT

      (1)   Subject to Regulations 1 and 2 trust moneys may be invested or laid

            liability or not and whether producing income or not as the Trustees
            shall in their absolute discretion think fit to the intent that the
            Trustees shall have the same full and unrestricted powers of
            investing and transposing investments and laying out moneys in all
            respects as if they were absolutely entitled thereto beneficially
            and without regard to the requirements of the Proper Law (save to
            the extent that these are obligatory) and in the professed exercise
            of this power the Trustees shall not be liable for any loss to the
            Trust Fund arising from any investment or purchase made in good
            faith.

                  be liable for any loss occasioned by any failure

                  any limited equitable interest under a settlement or trust or

                  Fund on current or deposit account with any bank or any other
                  company or corporation conducting the business of banking or
                  accepting moneys on deposit in any part of the world and may

                  term (howsoever short) or policies restricted to death by
                  accident and generally upon any terms and conditions as the
                  Trustees shall think fit and the Trustees shall have all the
                  powers of an absolute beneficial owner as respects any policy
                  forming part of the Trust Fund including the power to exercise
                  any option afforded by such policy or to sell or realise any
                  such policy or to convert the same into a fully paid up policy
                  or into any other form of assurance;

            (h)   the Trustees shall have power to leave any assets subject to

            (j)   in the exercise of the powers herein contained the Trustees
                  shall not be under any duty to see that the value of the Trust

2.4   In relation to a Full Liquidity Event the amount of the Contribution will
      depend on:

      2.4.1 the Equity Value at the Relevant Date of the Full Liquidity Event
            and will be calculated as a percentage of such Equity Value as
            follows:

            and the Maximum Percentage Contribution used to calculate the amount
            of Contribution due where the Equity Value is greater than $US100
            million, but less than US$350 million, shall be pro rated on a
            straight line basis; and

      2.4.2 whether the Relevant Employee has ceased to be an employee of a
            member of the Group (and has not immediately become an employee of
            another member of the Group) prior to the Trigger Date relating to
            the Full Liquidity Event, in which case, only a proportion of the
            Contribution otherwise due will be deemed to have vested, as

            SAVE that:

            (a)   in the event of the cessation of employment of the Relevant
                  Employee due to one of the reasons set out in clause 4.1, the
                  vesting of the entitlement to a Contribution shall be
                  accelerated as set out in clause 4.1; and

            (b)   in the event that there has been a Change of Control of the
                  Company on or prior to the Date of Cessation the entitlement
                  to a Contribution shall be accelerated in full so that the
                  whole amount of the Contribution (if any) shall be payable on
                  any Full Liquidity Event with a Trigger Date on or following
                  such Date of Cessation; and

      2.4.3 whether any Partial Liquidity Contributions have previously been
            made in connection with a Partial Liquidity Event or any other
            Further Contributions have been made under clause 2.8 (other than
            Further Contributions made

                                       18
<PAGE>

            under clause 2.8 which are not linked to a Partial Liquidity Event)
            and the Trustee has exercised its discretion and passed such
            payments to the Dependant Trust, in which case there shall be
            deducted from the Contribution due in relation to the Full Liquidity
            Event, the aggregate of all previous Partial Liquidity Contributions
            (if any) and any such Further Contributions made under clause 2.8.
            For the avoidance of doubt, if a payment has been made to the
            Trustee pursuant to clause 2.8 in connection with a Partial
            Liquidity Event, but at the Relevant Date of the Full Liquidity
            Event, such payment has not been transferred in its entirety to the
            Dependent Trust then payment shall, for the purposes of this clause
            and clause 2.5, be deemed to have been made into each dependent
            trust held by the Trustee for the benefit of employees of the
            Company and their families in force at that time, in accordance with
            any letter of wishes given by the Company to the Trustee in respect
            of such payment and, in the absence of any such letter, into each
            such dependent trust pro rata based on prior contributions.

2.5   For the avoidance of doubt, the Relevant Employee does not need to be an
      employee of any member of the Group at the Relevant Date, the
      Determination Date or the Payment Due Date, in relation to any Full
      Liquidity Event in order for the full amount of any Contribution to become
      payable pursuant to this covenant, provided that either he was an employee
      of any member of the Group at the Trigger Date relating to such Full
      Liquidity Event or, if he has ceased to be an employee at the Trigger
      Date, a Change of Control had occurred on or prior to the Date of
      Cessation. If the Relevant Employee has ceased to be an employee of a
      member of the Group (and does not immediately become an employee of
      another member of the Group) prior to the Trigger Date in relation to a
      Full Liquidity Event (and no Change of Control had occurred prior to the
      Date of Cessation), the amount of the Contribution to be made after the
      Date of Cessation in relation to such Full Liquidity Event, will be
      calculated as follows:

      [(A x B) x E] - C

      where:

      A  =  the Maximum Percentage Contribution applicable to that Full
            Liquidity Event, in accordance with clause 2.4.1;

      B  =  the fraction of the Maximum Percentage Contribution which has vested
            in accordance with clause 2.4.2 at the Date of Cessation (subject to
            any acceleration pursuant to clause 2.4.2);

      C  =  the aggregate of all previous Partial Liquidity Contributions (if
            any) made to the Trustee in respect of such Relevant Employee prior
            to the Relevant Date of that

                                       19
<PAGE>

            Full Liquidity Event, as a result of any previous Partial Liquidity
            Events and any other Further Contributions made under clause 2.8
            (other than Further Contributions not linked to a Partial Liquidity
            Event) and in respect of which the Trustee has exercised its
            discretion to transfer such payment into the Dependent Trust (or is
            deemed to have done so pursuant to clause 2.4.3); and

      E  =  the Equity Value applicable to that Full Liquidity Event.

2.6   Deliberately Deleted

2.7   In relation to a Partial Liquidity Event:

      2.7.1 the amount of the Partial Liquidity Contribution shall depend on
            whether, at the Relevant Date in relation to that Partial Liquidity
            Event, the Transaction Value Threshold has been met or exceeded, in
            which case the Partial Liquidity Contribution shall be calculated as
            follows:

            {[X x Y] x TV} - PC

            where:

            X = 60% in relation to all Partial Liquidity Events where the
            aggregate of the Transaction Value relating to that Partial
            Liquidity Event and the Transaction Values of all previous Partial
            Liquidity Events does not exceed US$200 million, and 100% in
            relation to all Partial Liquidity Events where the aggregate of the
            Transaction Value relating to that Partial Liquidity Event and the
            Transaction Values of all previous Partial Liquidity Events exceeds
            US$200 million;

            Y = in relation to a Partial Liquidity Event, the Maximum Percentage
            Contribution payable in relation to that Partial Liquidity Event
            pursuant to the table set out in clause 2.4.1 if "TV" (as defined
            below) were substituted for "Equity Value" and "Partial Liquidity
            Event" were substituted for "Full Liquidity Event" in such clause;

            TV = in relation to any Partial Liquidity Event in respect of which
            the Transaction Value Threshold has been met or exceeded, the
            aggregate of the Transaction Value relating to that Partial
            Liquidity Event and the Transaction Values of all previous Partial
            Liquidity Events; and

            PC = in relation to a Partial Liquidity Event, the aggregate amount
            of all previous Partial Liquidity Contributions made to the Trustee
            pursuant to this clause 2.7 in respect of the Relevant Employee
            prior to the Relevant Date of that Partial Liquidity Event;

                                       20
<PAGE>

            and so that, for the avoidance of doubt, once the Transaction Value
            Threshold has been met or exceeded, a Partial Liquidity Contribution
            shall (subject to the other terms of this covenant) be payable in
            respect of all subsequent Partial Liquidity Events;

      2.7.2 if a Partial Liquidity Contribution is required to be made under
            clause 2.7.1, such Partial Liquidity Contribution shall be made
            whether or not the Relevant Employee has ceased to be an employee of
            any member of the Group at the Relevant Date or the Determination
            Date or the Payment Due Date so long as the Relevant Employee was
            employed by a member of the Group at the Trigger Date relating to
            that Partial Liquidity Event (and, if no Partial Liquidity
            Contributions have previously been made, at the Trigger Date
            relating to the most recent Partial Liquidity Event). Subject to the
            following provisions of this clause 2.7.2, no Partial Liquidity
            Contribution shall be made with respect to any Partial Liquidity
            Event, the Trigger Date of which occurs following the Date of
            Cessation of the Relevant Employee's employment. Notwithstanding the
            foregoing provisions of this clause 2.7.2, in the event that,
            pursuant to clause 3.4, there is more than one Relevant Date, more
            than one Determination Date, and more than one Payment Due Date in
            relation to any Partial Liquidity Event, then provided that the
            Relevant Employee was employed by a member of the Group at the
            Trigger Date relating to that Partial Liquidity Event he shall be
            entitled to receive all Partial Liquidity Contributions which become
            payable following any number of subsequent Relevant Dates relating
            to that same Partial Liquidity Event, except that such Relevant
            Employee shall not be entitled to receive payments with respect to
            any Partial Liquidity Event following the Relevant Date of a Full
            Liquidity Event.

2.8   In addition, the Company may, at the discretion of the Remuneration
      Committee (after recommendations by the Chief Executive Officer of the
      Company), make Further Contributions to the Trustee in such amounts as the
      Remuneration Committee, in its sole discretion, determines, such payments
      to be held on the terms of the EBT.

2.9   Side Letter Cap

      Notwithstanding anything to the contrary in this covenant:

      2.9.1 on any Partial Liquidity Event, the Company shall be under no
            obligation to make any payment in excess of the Partial Liquidity
            Contribution due under clause 2.7.1;

      2.9.2 on a Full Liquidity Event, the Company shall be under no obligation
            to make any payment in excess of the aggregate of the Maximum
            Percentage

                                       21
<PAGE>

            Contribution due under clause 2.4.1, minus the amount of all
            previous Partial Liquidity Contributions; and:

      2.9.3 the Company shall not be under any obligation to make any payment to
            the Trustee under this covenant or otherwise to the extent that such
            payment together with any other payments made to the Trustee under
            or in connection with the EBT in relation to any Partial Liquidity
            Event or Full Liquidity Event would cause a violation of the
            provisions of paragraph 5 of the Side Letter ("SIDE LETTER CAP");

      provided that:

      (a)   this clause 2.9 shall not prevent the Company in its discretion from
            making Further Contributions pursuant to clause 2.8 in relation to
            any Full Liquidity Event or Partial Liquidity Event as long as the
            Side Letter Cap is not exceeded or from making Further Contributions
            pursuant to clause 2.8 otherwise than in connection with any Full
            Liquidity Event or Partial Liquidity Event, irrespective of the Side
            Letter Cap; and

      (b)   nothing in this covenant shall require the Trustee to repay any
            amounts previously received by it in respect of any Partial
            Liquidity Event occurring prior to any other Partial Liquidity Event
            or Full Liquidity Event.

3.    CALCULATION OF EQUITY VALUE AND TRANSACTION VALUE

3.1   For the purposes of this covenant and in relation to a Full Liquidity
      Event, "EQUITY VALUE" shall have the meaning as determined pursuant to and
      in accordance with Schedule 3 to the Investment Agreement (for the
      avoidance of doubt excluding the value of any shares no longer in issue
      due to their having been repurchased, redeemed or otherwise ceasing to be
      outstanding following the Closing Date), as adjusted to include the value
      of all Distributions made to shareholders since the Closing Date but prior
      to the Relevant Date in relation to such Full Liquidity Event, and subject
      to any further adjustments deemed to be equitable and necessary, in the
      complete discretion of the Board, in order to give effect to the
      intentions of all parties pursuant to the principles set out in this
      covenant (provided that such valuation and adjustments do not result in
      double counting). For the purposes of calculating Equity Value, the value
      of any non-cash Distribution or consideration received shall be calculated
      in accordance with clause 3.3.

3.2   For the purposes of this covenant the following terms shall have the
      following meanings:

      "TRANSACTION VALUE" shall mean the following, it being understood that in
      any case in which there is any ambiguity with respect to the proper
      determination of Transaction

                                       22
<PAGE>

      Value, it shall be in the discretion of the Board to determine the
      Transaction Value in a manner that operates fairly as between the Company
      and the Trustee:

      (a)   with respect to a Partial Liquidity Event described in clauses 7.1.1
            to 7.1.3 (inclusive) the aggregate amount of all Distributions
            (being an amount equal to the aggregate amount of all cash
            Distributions and the value (as determined in accordance with clause
            3.3) of all non-cash Distributions) made by the Company in
            connection with such Partial Liquidity Event; and

      (b)   with respect to a Partial Liquidity Event described in clauses 7.1.4
            to 7.1.6 (inclusive) the aggregate of all of the Individual
            Transaction Values in relation to such Partial Liquidity Event;

            where:

            "INDIVIDUAL TRANSACTION VALUE" in relation to each Investor
            transferring shares or in the case of an amalgamation or merger,
            surrendering shares for consideration as envisaged by clause 7.1.5,
            as part of any Partial Liquidity Event, the Implied Value in
            relation to that transfer or surrender of shares by that Investor as
            part of that Partial Liquidity Event multiplied by the Applicable
            Fraction in relation to that transfer or surrender of shares by that
            Investor as part of that Partial Liquidity Event;

            "IMPLIED VALUE" shall mean in relation to the transfer or surrender
            of any shares of common stock by any Investor as part of any Partial
            Liquidity Event, the per common share consideration received by that
            Investor, net of all transaction and brokerage costs, and (subject
            to clause 3.4) net of the maximum amount of consideration due to
            that Investor that may be held back in any escrow arrangements,
            multiplied by the number of shares of common stock of the Company in
            issue at the date of such transfer or surrender, immediately prior
            to such transfer or surrender, on a Fully Diluted Basis; and

            "APPLICABLE FRACTION" shall mean a fraction, the numerator of which
            is the number of shares of common stock in the Company transferred
            or surrendered by that Investor on such Partial Liquidity Event, and
            the denominator of which is the total number of shares of common
            stock in the Company in issue on the date of such transfer or
            surrender, immediately prior to such transfer of surrender on a
            Fully Diluted Basis.

3.3   In the event that any part of the Distribution made in connection with a
      Partial Liquidity Event arising under clause 7.1.1, to 7.1.3 (inclusive)
      or the consideration received by any Investor in connection with a Partial
      Liquidity Event arising under clauses 7.1.4 to 7.1.6

                                       23
<PAGE>

      (inclusive) consists of assets other than cash (excluding the right to be
      paid a sum in cash or receive a non-cash asset on a future date (whether
      or not, in the case of cash that sum is quantifiable on the Relevant Date)
      which rights shall be taken into consideration in accordance with the
      provisions of clause 3.4) the value of such assets shall be determined in
      good faith by the Board within 30 days of the Relevant Date.

3.4   In the event that:

      3.4.1 in relation to a Partial Liquidity Event arising under clauses 7.1.1
            to 7.1.3 (inclusive), either:

            3.4.1.1  a Distribution is declared, but not immediately paid; or

            3.4.1.2  more than one Distribution is declared in relation to such
                     Partial Liquidity Event; or

      3.4.2 in relation to a Partial Liquidity Event arising under clauses
            7.1.4, 7.1.5 or 7.1.6 either:

            3.4.2.1  the consideration payable in relation to that Partial
                     Liquidity Event includes a right to be paid a sum in cash
                     or to receive a non-cash asset on a future date; or

            3.4.2.2  any amount of cash which is deducted from, or any assets
                     which are withheld from, the amount payable or the assets
                     transferred to, the relevant Investors and placed into
                     escrow, is released from escrow to the relevant Investors;

      and, as a result of which either the shareholders of the Company or the
      relevant Investors (as applicable) receive additional cash or other assets
      on a future date ("DEFERRED PAYMENT") then each date or dates on which any
      such Deferred Payment becomes payable to the shareholders of the Company
      or the relevant Investors (as applicable) shall constitute an additional
      Relevant Date in relation to that Partial Liquidity Event and shall
      trigger an additional obligation on the Board to determine the Transaction
      Value in accordance with clause 3.5 as if such event constituted a
      separate Partial Liquidity Event (and an additional obligation of the
      Company to make an additional Partial Liquidity Contribution in relation
      to that Partial Liquidity Event) and, for the avoidance of doubt the
      payment of any cash or the transfer of any assets, released from any
      escrow or similar arrangements to any relevant Investors (whether before
      or after any subsequent Full Liquidity Event) shall trigger such
      obligations on the part of the Board and the Company. If, in accordance
      with the foregoing provisions of this clause 3.4, a release of additional
      consideration to Investors from an escrow (or similar) arrangement is made
      after a Full Liquidity Event, in calculating the additional Partial
      Liquidity Contribution due,

                                       24
<PAGE>

      the Equity Value of the Full Liquidity Event shall be taken into account
      when determining whether the Transaction Value Threshold has been met or
      exceeded, and for determining "X" for the purposes of clause 2.7.1.
      Notwithstanding the foregoing, if any payment that would be required to be
      made pursuant to this clause 3.4 after the Relevant Date of a Full
      Liquidity Event would have resulted in a reduction of the amount payable
      pursuant to clauses 2.4 and 2.5 if such payment pursuant to this clause
      3.4 had been made prior to the Determination Date of such Full Liquidity
      Event, then such payment otherwise required by this clause 3.4 shall be
      reduced to the extent of such otherwise resulting reduction (but not below
      zero).

3.5   Subject to clause 3.6 within 30 days of the Relevant Date of a Full
      Liquidity Event or a Partial Liquidity Event (including, for the avoidance
      of doubt, each Relevant Date relating to the same Partial Liquidity Event
      pursuant to clause 3.4) the Board shall determine the Equity Value in
      accordance with clause 3.1 (with respect to Full Liquidity Events) or the
      Transaction Value in accordance with clauses 3.2 to 3.4 inclusive (with
      respect to Partial Liquidity Events), and shall give written notice of
      their determination to the Company and the Trustee within such 30-day
      period the date of such notice being, in each case, the "DETERMINATION
      DATE" in relation to such Full Liquidity Event or Partial Liquidity Event,
      save in relation to (a) a Partial Liquidity Event in respect of which no
      Partial Liquidity Contribution is due by virtue of the fact that the
      Transaction Value Threshold has not been reached, in which case, the
      Determination Date in relation to that Partial Liquidity Event shall be
      the Determination Date (if any) of the first Partial Liquidity Event in
      respect of which a Partial Liquidity Contribution is made pursuant to
      clause 2.7; and (b) if the Full Liquidity Event is a Liquidation then the
      Determination Date shall be the date on which the Liquidator makes a
      distribution to shareholders of a substantial proportion of the assets
      available for distribution in the Liquidation.

3.6   In the event that a Full Liquidity Event also triggers an obligation to
      calculate Total Equity Value (as defined in the Viatel Convertible Loan
      Notes) then Equity Value shall be determined in accordance with the same
      procedure as is set out in Section 4.3(b) of the Viatel Convertible Notes
      for the determination of Total Equity Value (which, for the avoidance of
      doubt means that negotiations between the Board and the holders of the
      Viatel Convertible Notes shall, so far as they are relevant for the
      calculation of Equity Value, bind the Trustee) but adjusted as
      contemplated by clause 3.1 hereof, and the Board shall give written notice
      to the Company and the Trustee of the Equity Value, within 10 Business
      Days of the date on which the "EQUITY VALUE" is agreed or determined
      pursuant to such procedure and the date of such notice shall, unless such
      Full Liquidity Event is a Liquidation, constitute the "DETERMINATION DATE"
      in relation to that Full Liquidity Event. If the Full Liquidity Event is a
      Liquidation then the Determination Date shall be the date on which the
      Liquidator makes a distribution to shareholders of a substantial
      proportion of the assets available for distribution in the Liquidation.

4.    CESSATION OF EMPLOYMENT OF THE RELEVANT EMPLOYEE

4.1   If the Relevant Employee ceases to be an employee of a member of the Group
      (and does not immediately become an employee of another member of the
      Group) due to:

      4.1.1 the Company or another member of the Group terminating the Relevant
            Employee's employment without Cause; or

      4.1.2 the Relevant Employee terminating his employment for Good Reason; or

      4.1.3 the Relevant Employee's death or disability (disability for these
            purposes being as determined by the Remuneration Committee),

      the amount of the Maximum Percentage Contribution which shall be deemed to
      have vested (as contemplated by clause 2.4.2) in relation to a Full
      Liquidity Event, the Trigger Date of which occurs following the Date of
      Cessation but on or prior to 21 April 2014, shall be increased by assuming
      that the Relevant Employee's Date of Cessation falls into the "Tranche"
      immediately following the "Tranche" in which the Date of Cessation falls
      for the purposes of clause 2.4.2. Any part of the Maximum Percentage
      Contribution which does not vest in accordance with this clause 4.1 (or is
      not accellerated in accordance with clause 2.4.2(b)) shall lapse
      automatically at the Date of Cessation.

4.2   For the purpose of clause 4.1 above:

      4.2.1 "CAUSE" means the grounds on which the Relevant Employee's
            employment may be summarily terminated without further payment to
            the Relevant Employee as set out in clause 3(c) of the Service
            Agreement; and

      4.2.2 "GOOD REASON" shall have the meaning set out in clause 3(d) of the
            Relevant Employee's Service Agreement.

4.3   Subject to the provisions of clause 2.4.2(b), if the Relevant Employee
      ceases to be an employee of a member of the Group (and does not
      immediately become an employee of another member of the Group ) for any
      reason other than those set out in clause 4.1 above, the Trustee will be
      entitled, upon the Payment Due Date in relation to any Full Liquidity
      Event the Trigger Date of which occurs following the Date of Cessation but
      on or prior to 21 April 2014, to be paid (with respect to the Relevant
      Employee) only that part of the Maximum Percentage Contribution which has
      vested on or prior to the Date of Cessation and will be paid that amount
      by the Company in accordance with clause 2.1. In such event, any part of
      the Maximum Contribution in relation to a Full Liquidity Event which has
      not vested prior to such Date of Cessation shall lapse automatically at
      the Date of Cessation.

5.    PAYMENT OF PARTIAL LIQUIDITY CONTRIBUTIONS AND CONTRIBUTIONS WHERE
      CONSIDERATION IS PAYABLE OTHERWISE THAN IN CASH

5.1   In the event that:

      5.1.1 a Partial Liquidity Event requiring a Partial Liquidity Contribution
            occurs; or

      5.1.2 a Full Liquidity Event occurs;

      and in any case, the amounts payable to the shareholders of the Company
      and/or relevant Investors (as applicable) in relation to such Partial
      Liquidity Event and/or Full Liquidity Event are not payable wholly in cash
      or Liquid Consideration ("NON-LIQUID PAYMENT") then the following
      provisions of this clause 5 shall apply.

5.2   To the extent that, in relation to any Full Liquidity Event or Partial
      Liquidity Event the amount payable to the shareholders of the Company
      and/or relevant Investors (as applicable) is payable in cash, then the
      same pro rata portion of the Partial Liquidity Contribution, in relation
      to a Partial Liquidity Event, or the Contribution in relation to a Full
      Liquidity Event shall be payable in cash.

5.3   To the extent that, in relation to any Full Liquidity Event or Partial
      Liquidity Event, the amount is to be satisfied by Liquid Consideration
      then:

      5.3.1 the Company shall use reasonable endeavours prior to the relevant
            Payment Due Date, to ensure that the Partial Liquidity Contribution,
            in relation to a Partial Liquidity Event, or the Contribution in
            relation to a Full Liquidity Event, can be satisfied entirely in
            cash; but

      5.3.2 if the Company having used reasonable endeavours to ensure payment
            in cash pursuant to clause 5.3.1 prior to the relevant Payment Due
            Date, is unable to do so on a basis reasonably satisfactory to the
            Board, then the Company shall be entitled to satisfy its obligation
            to make the Partial Liquidity Contribution, in relation to a Partial
            Liquidity Event or the Contribution in relation to a Full Liquidity
            Event, and the Trustee shall be bound to accept satisfaction of the
            Partial Liquidity Contribution or the Contribution (as appropriate)
            by transfer into the EBT of such amount of the Liquid Consideration
            as has a value (in the discretion of the Remuneration Committee)
            equal to the amount of the Partial Liquidity Contribution or
            Contribution (as appropriate) which is not payable in cash pursuant
            to clause 5.2.

5.4   To the extent that in relation to any Full Liquidity Event or Partial
      Liquidity Event, the amount is to be satisfied by a Non-liquid Payment,
      then the Company shall satisfy its obligation to make the Partial
      Liquidity Contribution, in relation to a Partial Liquidity Event

                                       27
<PAGE>

      or the Contribution in relation to a Full Liquidity Event, and the Trustee
      shall be bound to accept satisfaction of the Partial Liquidity
      Contribution or the Contribution (as appropriate) by transfer into the EBT
      of (at the discretion of the Board) either: (a) such amount of the
      Non-liquid Payment as has a value (in the discretion of the Board) equal
      to the amount of the Partial Liquidity Contribution or Contribution (as
      appropriate) which is not payable in cash or Liquid Consideration pursuant
      to clauses 5.2 and/or 5.3 and for the avoidance of doubt, if the
      Non-liquid Payment constitutes shares which are subject to restrictions on
      sale, the Trustee's entitlement hereunder shall be to receive such shares
      subject to equivalent restrictions on sale as those applicable to the
      shares received by the Company and/or the relevant Investors (as
      applicable); or (b) an amount of cash equal to the amount of such Partial
      Liquidity Contribution or Contribution (as appropriate).

5.5   Notwithstanding anything to the contrary in this covenant, neither:

      5.5.1 complying with the obligation to use "reasonable endeavours" in
            clause 5.3.1; nor

      5.5.2 any other provision of this covenant will oblige the shareholders of
            the Company, any of the Investors or any other person to incur
            costs, fees or expenses in connection with the conversion of any
            amount of Liquid Consideration into cash, which in the aggregate are
            in excess of 1% of the total value of that amount of Liquid
            Consideration.

6.    FULL LIQUIDITY EVENT

6.1   A Full Liquidity Event shall be the first occurrence of any of the
      following events:

      6.1.1 a Sale; or

      6.1.2 a Liquidation of the Company,

      and under no circumstances shall there be more than one Full Liquidity
      Event pursuant to this covenant.

7.    PARTIAL LIQUIDITY EVENT

7.1   A Partial Liquidity Event shall be the occurrence of any of the following
      events, in each case prior to a Full Liquidity Event:

      7.1.1 the transfer of any Material Asset including without limitation an
            amalgamation or merger of a Material Subsidiary, to or with a person
            or entity that is not a Qualified Transferee whether in one
            transaction or a series of related transactions (but excluding a
            transfer or amalgamation or merger by one member of the Group to
            another member of the Group) but only if followed by a Distribution
            of proceeds of

                                       28
<PAGE>

            such transfer to the Investors and/or (if appropriate as determined
            by the Board) their Qualified Transferees;

      7.1.2 the Liquidation of a Material Subsidiary followed by a Distribution
            of proceeds of such Liquidation to the Investors and/or (if
            appropriate as determined by the Board) their Qualified Transferees;

      7.1.3 a Post-Flotation Transfer of shares in a Controlling Subsidiary but
            only if followed by a Distribution of proceeds of such transfer to
            the Investors and/or (if appropriate as determined by the Board)
            their Qualified Transferees;

      7.1.4 a Tag-Along Transaction (which is not a Sale);

      7.1.5 an amalgamation or merger of the Company which is not a Sale but
            results in the receipt by Investors of proceeds as consideration in
            exchange for the surrender of common stock of the Company (it being
            understood that interests in the Company or in a successor thereto
            are not such proceeds, and an amalgamation or merger by which the
            Company is making an acquisition is not a Partial Liquidity Event);
            or

      7.1.6 a Post-Flotation Transfer of shares in the Company (which is not a
            Sale);

      and for the purposes of this covenant, and in accordance with clause 8, if
      an event or series of events could be classified as a Partial Liquidity
      Event under more than one sub-clause of this clause 7.1, the Board shall
      determine which, if any, subsection applies, but no event or series of
      events shall be deemed to constitute two or more separate Partial
      Liquidity Events simply because such event or series of events could be
      considered a Partial Liquidity Event under more than one such sub-clause.
      The Board shall have the responsibility to determine if an amalgamation or
      merger of the Company is one in which the Company is making an
      acquisition.

8.    MULTIPLE LIQUIDITY EVENTS

      In the event that more than one Event (as defined below) occurs as part of
      one single transaction or a series of closely connected transactions, then
      the Board shall determine which provisions of this covenant shall apply
      and, if necessary, any adjustment to the provisions of this covenant which
      should be made to ensure that the provisions of this covenant operate
      fairly as between the Company and the Trustee and for the avoidance of
      doubt but without limitation, shall be entitled (in its sole discretion)
      to find that a Partial Liquidity Event and a Reorganisation can both take
      place pursuant to this covenant and shall be entitled (in its sole
      discretion) to find that any particular Partial Liquidity Event is not
      also a Reorganisation. For the purposes of this clause 8, each or any of a
      Partial Liquidity Event, a Full Liquidity Event and a Reorganisation shall
      constitute an "EVENT".

                                       29
<PAGE>

9.    REORGANISATION

      In the event that at any time prior to a Full Liquidity Event a
      Reorganisation occurs, the Company shall (so far as it is legally able)
      ensure that the body corporate principally surviving or resulting from the
      Reorganisation, or the new holding company of the Group following the
      Reorganisation, ("NEWCO"), or, in the case of a Reorganisation under
      sub-paragraph (d) of the definition of Reorganisation, the Company,
      covenants to the Trustee on identical or substantially similar terms to
      the terms of this covenant (in any event, reasonably acceptable to the
      Board, taking into account the intentions of the parties to this covenant)
      so that the Relevant Employee should be in the same economic position
      (taking account of any ongoing obligations of any other entity that holds
      or retains assets of the Group and taking into account the principles of
      Section 3.1 hereof and Schedule 3 of the Investment Agreement) following
      the Reorganisation as he was before. Such covenant may be contingent upon
      the Company receiving a release (in form and substance reasonably
      acceptable to it) from all obligations (other than accrued obligations,
      unless these are also assumed by Newco) hereunder.

10.   ADMINISTRATION

10.1  Any notice or other document which the Company is required or may desire
      to give to the Trustee pursuant to this covenant shall be sufficiently
      given if delivered to it by post in a prepaid cover addressed to the
      Trustee at its registered office and if so sent shall be deemed to have
      been duly given on the date of posting.

10.2  Any notice or other document which the Trustee is required or may desire
      to give to the Company pursuant to this covenant shall be sufficiently
      given if delivered to it by post in a prepaid cover addressed to the
      Company at its registered office and if so sent shall be deemed to have
      been duly given on the date of posting.

11.   CONTRACTS (RIGHTS OF THIRD PARTIES) ACT 1999

A     person who is not the Trustee or a company who is not a member of the
      Group has no right under the Contracts (Rights of Third Parties) Act 1999
      to rely upon or enforce any provisions of this covenant.

12.   GOVERNING LAW AND COUNTERPARTS

12.1  This covenant is governed by and shall be interpreted in accordance with
      the laws of England.

12.2  This covenant may be executed in one or more counterparts, each of which
      when executed and delivered shall be an original but when taken together
      shall constitute one and the same instrument.

                                       30

13.   DISPUTE RESOLUTION

13.1  The parties shall use their best efforts to negotiate in good faith and
      settle amicably any dispute that may arise out of or relate to this
      covenant (or its construction, validity or termination) (a "DISPUTE"). If
      a Dispute cannot be settled through negotiations by appropriate
      representatives of the Trustee and the Board then either party may give to
      the other a notice in writing (a "DISPUTE NOTICE"). Within seven days of
      the Dispute Notice being given the parties shall refer the Dispute to the
      chairman of the Board, in the case of the Company, and the managing
      director, in the case of the Trustee, who shall meet in order to attempt
      to resolve the dispute. If the Dispute is not settled by agreement in
      writing between the parties within 14 days of the Dispute Notice it shall
      be resolved in accordance with clauses 13.2 and 13.3.

13.2  If a Dispute is not successfully resolved in accordance with clause 13.1,
      such Dispute shall be referred to mediation in accordance with the Centre
      for Dispute Resolution ("CEDR") Model Mediation Procedure. The mediation
      shall be conducted by a single mediator appointed by mutual agreement, or
      (failing mutual agreement within seven days of a notice from either party
      to the other calling upon the other so to agree) by the CEDR/President of
      the London Chamber of Commerce. Both parties agree to co-operate fully
      with such mediator, provide such assistance as is necessary to enable the
      mediator to discharge his duties, and to bear equally between them the
      fees and expenses of the mediator.

13.3  If the Dispute is not settled by agreement in writing between the parties
      within 30 days after the appointment of a mediator, or such other period
      as the parties may agree, it shall be referred to a single arbitrator to
      be agreed between the parties. Failing such agreement within 30 days of
      the request by one party to the other that a matter be referred to
      arbitration in accordance with this clause such reference shall be to an
      arbitrator appointed by the President for the time being of the
      International Chamber of Commerce ("ICC") in London. The arbitration shall
      be conducted in London in the English language in accordance with the
      arbitration rules of the ICC in force at the date of this covenant. The
      decision of such arbitrator shall be final and binding upon the parties.
      Any reference under this clause shall be deemed to be a reference to
      arbitration within the meaning of the Arbitration Act 1996.

13.4  The parties shall keep confidential and not use for any collateral or
      ulterior purpose the subject matter of the arbitration and all
      information, documents and materials produced for, or arising in relation
      to, the arbitration including any award arising out of it except insofar
      as is necessary to implement and enforce any award or otherwise as
      required by law.
