          Target Business would be transferred to a new company and the shares
          in such new company sold to the Purchaser or a Local Purchaser at
          Completion). If it is reasonably practicable to give effect to such

          Vendor shall in good

                    of the business or assets of the Purchaser or any member
                    of the Purchaser's Group, in each case as a result of the

                    any other material transaction contemplated by the

          3.1.5.    the consents described in the document in the Agreed Form
                    AF15D shall have been obtained.

RESPONSIBILITY FOR SATISFACTION

3.2.      The Principal Vendor and the Purchaser hereby undertake (i) not to
          take (and the Principal Vendor shall procure that no member of the
          Vendors' Group shall take and the Purchaser shall procure that no
          member of the Purchaser's Group shall take) any action that would
          reasonably be expected to result in any of the conditions set out in
          Clause 3.1 or the Spanish Condition not being satisfied and (ii) at
          their own expense to use all reasonable endeavours to ensure the
          satisfaction of the conditions set out in Clause 3.1 (save as
          provided therein) and the Spanish Condition and the parties shall
          each bear their own respective filing fees and other costs incurred
          in relation to any anti-trust or similar filing required to be made
          in any jurisdiction in connection with the acquisition of the
          Operations by the Purchaser's Group. Without prejudice to the
          foregoing, it is agreed that the Purchaser and the Principal Vendor
          shall promptly notify each other of all requests and enquiries from
          any government, governmental, supranational or trade agency, court
          or regulatory body and those requests and enquiries shall be dealt
          with by the Principal Vendor and the Purchaser in


                                      6

          consultation with each other and the Principal Vendor and the
          Purchaser shall promptly co-operate with and provide all necessary
          information and assistance reasonably required by such government,
          agency, court or body upon being requested to do so by the other.

NOTICES REGARDING SATISFACTION

3.3.      Each of the Purchaser and the Principal Vendor shall give notice to
          the other of the satisfaction of the Condition Precedent set out in
          Clause 3.1.1 or 3.1.5 promptly upon becoming aware of the same.

LONG STOP DATE

3.4.      If the conditions in Clause 3.1 are not satisfied or waived on or
          before the Long Stop Date otherwise than as a result of a breach by
          a party of its obligations under Clause 3.1 or Clause 3.2 this
          Agreement shall lapse and no party shall have any claim against any
          other under it. If the Conditions in Clause 3.1 are not satisfied or
          waived on or before the Long Stop Date as a result of a breach by a
          party of its obligations under Clause 3.1 or Clause 3.2 then the
          party not in breach of such obligations shall be entitled by notice
          in writing to the other to terminate this Agreement without
          prejudice to any claim arising from breach of the undertakings
          contained in Clauses 3.1 and 3.2.

RIGHTS OF TERMINATION

3.5.      If at any time after the date of this Agreement and before
          Completion:

          3.5.1.    a Material Breach of Undertaking occurs;

          3.5.2.    a Material Breach of Warranty occurs;

          3.5.3.    a Material Adverse Change occurs; or

          3.5.4.    any of the conditions set out in Clause 3.1 shall have
                    become incapable of fulfilment on or before the Long Stop
                    Date otherwise than as a result of a breach by the
                    Purchaser of its obligations under Clause 3.1 or Clause
                    3.2 and shall not have been waived by the applicable party
                    or parties as set out in Clause 3.1,

          the Purchaser shall be entitled, subject to the provisions of
          Clauses 3.7 to 3.15, to terminate this Agreement before Completion,
          by notice in writing to the Principal Vendor, without liability on
          its part. If the Purchaser duly exercises its right of termination
          hereunder it shall have no claim against any Vendor except as set
          out in Clause 3.13 or Clause 3.14 (as appropriate). If the
          Purchaser, having received notice of the relevant facts or matters
          in accordance with Clause 5.4.4 and in the knowledge of its right to
          terminate this Agreement as described in paragraph (ii)(B) of the
          definition of the term "Material Breach of Warranty", elects not to
          so terminate this Agreement (other than in respect of a breach
          arising from facts or matters within the reasonable control of the
          Vendors' Group), it shall thereafter have no claim against the
          Principal Vendor in respect of the facts and circumstances giving
          rise to such Material Breach of Warranty.



                                      7

3.6.      If at any time after the date of this Agreement and before
          Completion any of the conditions set out in Clause 3.1 shall have
          become incapable of fulfilment on or before the Long Stop Date
          otherwise than as a result of a breach by the Principal Vendor of
          its obligations under Clause 3.1 or Clause 3.2 and shall not have
          been waived by the applicable party or parties as set out in Clause
          3.1, the Principal Vendor shall be entitled, subject to the
          provisions of Clauses 3.7 to 3.15, to terminate this Agreement
          before Completion, by notice in writing to the Purchaser, without
          liability on its part. If the Principal Vendor duly exercises its
          right of termination hereunder, it shall have no claim against the
          Purchaser or any Local Purchaser except as set out in Clause 3.14.

3.7.      If the Purchaser wishes to terminate this Agreement in accordance
          with Clause 3.5 or the Principal Vendor wishes to terminate this
          Agreement in accordance with Clause 3.6, the terminating party shall
          forthwith give notice of its intention to do so (a "Termination
          Notice") to the other by facsimile or by personal delivery in
          accordance with Clause 19.20.

3.8.      If the Purchaser serves a Termination Notice in accordance with
          Clause 3.7 alleging that a Material Breach of Undertaking, Material
          Breach of Warranty or Material Adverse Change has occurred, the
          Principal Vendor may contest the validity of the Purchaser's right
          to terminate by giving notice in writing to the Purchaser not later
          than 5 pm on the date being three Business Days after the date of
          receipt of such Termination Notice.

3.9.      If the Principal Vendor gives valid notice to the Purchaser under
          Clause 3.8, in respect of an alleged Material Breach of Undertaking
          or Material Breach of Warranty then the parties shall seek the
          advice of a leading commercial Queens Counsel (the "Legal Expert").
          If the parties cannot agree on the Legal Expert within two Business
          Days of the valid service by the Principal Vendor of a notice under
          Clause 3.8, the Legal Expert shall be chosen by lot. The Legal
          Expert shall give due weight to any representations put forward by
          either party received by him and shall as a matter of urgency (and
          in any event no later than three Business Days after the date of
          appointment) advise the parties in writing if in his opinion, on the
          basis of the information available, a Material Breach of Undertaking
          or Material Breach of Warranty has occurred. If the Legal Expert's
          opinion is that a Material Breach of Undertaking or Material Breach
          of Warranty has occurred or if no opinion is issued by the Legal
          Expert on or before the Long Stop Date, then the Purchaser shall not
          be obliged to proceed to complete this Agreement. If the Legal
          Expert opines on or before the Long Stop Date that no such Material
          Breach of Undertaking or Material Breach of Warranty has occurred,
          then the parties shall complete this Agreement in accordance with
          its terms.

3.10.     If the Principal Vendor gives valid notice to the Purchaser under
          Clause 3.8 in respect of an alleged Material Adverse Change, then
          the parties shall seek the advise of a senior investment banker in
          London of an investment bank of international standing (not being
          Goldman Sachs or JP Morgan) (the "IB Expert"). If the parties cannot
          agree on the IB Expert within two Business Days of the valid service
          by the Principal Vendor of a notice under Clause 3.12, the IB Expert
          shall be chosen by lot. The IB Expert shall give due weight to any
          representation put forward by either party received by him and shall
          as a



                                      8

          matter of urgency (and in any event no later than three Business
          Days after the date of appointment) advise the parties in writing if
          in his opinion a Material Adverse Change has occurred. If the IB
          Expert's opinion is that a Material Adverse Change has occurred or
          if no opinion is issued by the IB Expert on or before the Long Stop
          Date, then the Purchaser shall not be obliged to proceed to complete
          this Agreement. If the IB Expert opines on or before the Long Stop
          Date that no such Material Adverse Change has occurred then the
          parties shall complete this Agreement in accordance with its terms.

3.11.     In giving such advice the Legal Expert and the IB Expert shall each
          act as an expert and not as an arbitrator. His or her fees shall be
          payable by the unsuccessful party.

3.12.     If the Purchaser serves a Termination Notice in respect of a
          Material Breach of Undertaking, a Material Breach of Warranty or
          Material Adverse Change and the validity of such Termination Notice
          has not been resolved on or before the date falling five Business
          Days before the date on which Completion would otherwise be due to
          occur under Clause 6.1, then the date on which Completion shall
          occur shall be the date falling five Business Days after such
          validity has been resolved. This Clause is subject to Clauses 3.9
          and 3.10 where the Legal Expert or IB Expert (as appropriate) has
          not issued an opinion on or before the Long Stop Date.

EFFECT OF TERMINATION

3.13.     If the Purchaser validly terminates this Agreement in accordance
          with Clause 3.5.1 (Material Breach of Undertaking), Clause 3.5.2
          (Material Breach of Warranty) (but only in respect of a Material
          Breach of Warranty falling within paragraph (i) or (ii)(A) of the
          definition of that term or a Material Breach of Warranty falling
          within paragraph (ii)(B) of such definition arising by reason of
          facts or matters within the reasonable control of the Vendors'
          Group), or Clause 3.5.3 (Material Adverse Change) (but only in
          respect of a Material Adverse Change arising by reason of facts or
          matters within the reasonable control of the Vendors' Group) then
          (i) the Principal Vendor shall pay to the Purchaser an amount equal
          to all reasonable professional fees and out of pocket expenses (but
          excluding any financing arrangement or commitment fees) together
          with any amounts in respect of irrecoverable VAT on such fees and
          expenses incurred by each member of the Purchaser's Group directly
          in connection with the transactions contemplated by this Agreement
          up to a maximum of US$2,500,000 and (ii) this Agreement shall lapse
          without obligation or liability on the part of any party to this
          Agreement except for any liability for any wilful breach by the
          Principal Vendor of the terms and conditions of this Agreement.

3.14.     If the Purchaser validly terminates this Agreement in accordance
          with Clause 3.5.2 (Material Breach of Warranty) or 3.5.3 (Material
          Adverse Change) (in each case except as provided for in Clause 3.13)
          or 3.5.4 (conditions incapable of fulfilment) or the Principal
          Vendor validly terminates this Agreement in accordance with Clause
          3.6 (conditions incapable of fulfilment), then this Agreement shall
          lapse without obligation or liability on the part of any party to
          this Agreement except for any liability for any prior breach by such
          party of the terms and conditions of this Agreement. Nothing in this
          Clause shall be


                                      9

          deemed to impair the right of any party to compel specific
          performance by any other party of its obligations under this
          Agreement.

3.15.     The provisions of Clauses 18.3 and 18.5 (and Clause 18.6 insofar as
          such Clause relates to Clauses 18.3 and 18.5) relating to
          confidentiality and the provisions of Clause 17 relating to certain
          costs shall survive any termination of this Agreement.

4.       CONSIDERATION

PURCHASE PRICE

4.1.      Subject to Clauses 4.3 to 4.8, the aggregate consideration for the
          purchase of the Operations (by way of acquisition of the Shares and
          the Business Assets and the Target Businesses) shall (in addition to
          the assumption of the Business Liabilities) be:

          4.1.1.    the payment of US$200,258,000 (being US$200,000,000 (i)
                    minus the aggregate of the Estimated Intra-Group
                    Indebtedness and the Estimated Third Party Indebtedness
                    and (ii) plus the Estimated Cash);

          4.1.2.    the issue of the Consideration Shares; and

          4.1.3.    the payment of the Deferred Consideration (as defined in
                    Part 5 of Schedule 3), if any.

          The relevant amounts of the Purchase Price (other than the Deferred
          Consideration, the Delayed Consideration Shares and, if the New
          Castle Release Condition is not satisfied on or prior to the
          Completion Date, the New Castle Consideration Shares) and Estimated
          Intra-Group Indebtedness shall be discharged at Completion in
          accordance with Schedule 9. The issue of the New Castle
          Consideration Shares (if not issued at Completion), the Delayed
          Consideration Shares, if any, the Spanish Consideration Shares (if a
          Delayed Completion is required under Clause 4.23) and the payment of
          the Deferred Consideration, if any, shall occur in accordance with
          the relevant provisions of this Clause 4.

4.2.      The Principal Vendor is authorised to receive the Purchase Price on
          behalf of the other Vendors and payment to the Principal Vendor (or
          as it may direct) shall constitute an absolute discharge for the
          Purchaser.

AMENDMENTS TO INITIAL CONSIDERATION

4.3.      If the Intra-Group Indebtedness Statement shows that the relevant
          Intra-Group Indebtedness exceeds the relevant Estimated Intra-Group
          Indebtedness, then on the Settlement Date the Principal Vendor shall
          pay to the Purchaser an amount equal to such excess by way of
          reduction in the cash component of the Purchase Price; and the
          Purchaser shall (on behalf of the relevant Target Company) pay to
          the Principal Vendor (on behalf of the relevant member of the
          Vendors' Group) an equal amount by way of satisfaction of such
          additional Intra-Group Indebtedness.


                                     10

4.4.      If the Intra-Group Indebtedness Statement shows that the Estimated
          Intra-Group Indebtedness exceeds the Intra-Group Indebtedness, then
          on the Settlement Date:

          4.4.1.    the Purchaser shall pay to the Principal Vendor an amount
                    equal to such excess by way of increase in the cash
                    component of the Purchase Price; and

          4.4.2.    the Principal Vendor shall (on behalf of the relevant
                    member of the Vendors' Group) repay to the Purchaser on
                    behalf of the relevant Target Company an equal amount by
                    way of repayment of the excess amount paid by or on behalf
                    of the relevant Target Company on account of the
                    Intra-Group Indebtedness at Completion.

4.5.      If the Completion Working Capital and/or Target Companies Cash is
          less than the Base Working Capital or Estimated Cash respectively,
          the Principal Vendor shall on the Settlement Date pay to the
          Purchaser an amount equal to such shortfall (or, if there is a
          shortfall on both, the aggregate of them) by way of reduction in the
          cash component of the Purchase Price.

4.6.      If the Completion Working Capital and/or Target Companies Cash
          exceeds the Base Working Capital or Estimated Cash respectively, the
          Purchaser shall on the Settlement Date pay to the Principal Vendor
          an amount equal to such excess (or if there is a excess on both, the
          aggregate of them) by way of increase in the cash component of the
          Purchase Price.

4.7.      If the Third Party Indebtedness exceeds the Estimated Third Party
          Indebtedness, the Principal Vendor shall on the Settlement Date pay
          to the Purchaser an amount equal to the excess by way of reduction
          in the cash component of the Purchase Price.

4.8.      If the Third Party Indebtedness is less than the relevant Estimated
          Third Party Indebtedness, the Purchaser shall on the Settlement Date
          pay to the Principal Vendor an amount equal to the shortfall by way
          of increase in the cash component of the Purchase Price.

4.9.      The provisions of Schedule 3 shall apply in relation to the
          preparation and agreement (or determination) of the Actual
          Cash/Indebtedness Statement and the Completion Working Capital
          Statement.

4.10.     The Purchaser and the Principal Vendor shall off-set amounts due
          between them under Clauses 4.3 to 4.8 and under Clause 2.2.2 or
          Clause 2.2.3 so as to result in a single net payment being made in
          relation to Completion. Such off-set does not relieve the Principal
          Vendor (where it would have received a payment on behalf of another
          member of the Vendors' Group) or the Purchaser (where it would have
          received a payment on behalf of a Target Company) of its obligation
          to account to such member of the Vendors' Group or the relevant
          Target Company for the sum in question.


                                      11

DEFERRED CONSIDERATION

4.11.   The provisions of Part 5 of Schedule 3 shall apply in relation to (and
        certain capitalised terms used in this Clause 4.11, and Clauses 4.12
        and 4.13 are defined in Part 5 of Schedule 3):

        4.11.1. the determination of the Product Deferred Consideration and

                2004 and Completion insofar as such conduct may affect the
                Deferred Consideration; and

        4.11.3. certain undertakings by the Purchaser regarding the conduct of
                the Operations during the Earn-Out Period insofar as such
                conduct may affect the Deferred Consideration.

4.12.   The Purchaser shall on each Product Deferred Consideration Payment
        Date pay to the Principal Vendor an amount equal to the Product
        Interim Deferred Consideration or the Product Final Deferred
        Consideration as applicable, payable on such date.

4.13.   The Purchaser shall on each Effects Deferred Consideration Payment
        Date pay to the Principal Vendor an amount equal to the Effects Interim
        Deferred Consideration or the Effects Final Deferred Consideration, as
        applicable, payable on such date.

PENSION DEFICIT ADJUSTMENT

4.14.   After Completion and until the date on which the Adjusted Transfer
        Value (as defined in Part 2 of Schedule 8) is agreed or determined,
        the Principal Vendor and the Purchaser shall co-operate to perform the
        calculations and all other actions contemplated by Part 2 of Schedule
        8 in order to determine the Pension Deficit Reduction Adjustment
        Amount and enable the issuance of the Delayed Consideration Shares, if
        any, by the Purchaser.

CERTIFICATES IN RESPECT OF CONSIDERATION SHARES

4.15.   So long as applicable, each certificate representing any portion of
        the Consideration Shares shall be stamped or otherwise imprinted with
        a legend in the following form (in addition to any legend required
        under applicable U.S. state securities laws):

        "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
        UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES
        LAWS OF ANY STATE OF THE UNITED STATES. SUCH SHARES MAY NOT BE
        OFFERED, SOLD, TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE
        DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OTHER THAN PURSUANT TO
        AN EXEMPTION FROM SUCH REGISTRATION REQUIREMENTS."




                                      12

        After the above requirement for a legend is no longer applicable
        because the Consideration Shares are freely transferable under the
        Securities Act, the Purchaser shall remove such legend upon request
        from a holder of such Consideration Shares, if outside counsel for
        such holder reasonably determines that the transfer of such
        Consideration Shares is no longer restricted by the Securities Act and
        (i) outside counsel for the Purchaser reasonably concurs in such
        determination or (ii) at such holder's option such holder's outside
        counsel provides an opinion addressed to the Purchaser in form and
        substance satisfactory to the Purchaser to the effect that the
        transfer of the Consideration Shares is no longer restricted by the
        Securities Act.

REGISTRATION RIGHTS

4.16.   The Principal Vendor or any member of the Vendors' Group which from
        time to time holds the Consideration Shares shall, after the issue of
        any Consideration Shares in accordance with this Clause 4, be entitled
        to the registration rights with respect to such Consideration Shares
        set out in Clause 9.

DELAYED CONSIDERATION SHARES

4.17.   No later than the Delayed Share Issue Date, the Purchaser shall
        deliver to the US Business Vendor a certificate or certificates
        representing the Delayed Consideration Shares, if any, which shall be
        in definitive form and registered in the name of the US Business
        Vendor and in a single certificate or in such denominations as the US
        Business Vendor shall request not later than the fifth Business Day
        after the Pension Transfer Determination Date.

PAYMENTS/INTEREST

4.18.   All payments under this Clause shall (unless the parties agree
        otherwise or the recipient notifies by at least five Business Days'
        prior notice a suitable alternative bank account) be paid by
        electronic transfer of cleared funds for same day value to:

        4.18.1. in the case of the Principal Vendor, the Principal Vendor's
                Bank Account; and

        4.18.2. in the case of the Purchaser, the bank account of the
                Purchaser in the US notified by the Purchaser to the Principal
                Vendor at least five Business Days before the first payment is
                to be made to the Purchaser.

4.19.   All payments made under Clauses 4.3 to 4.8 shall bear interest from
        the Completion Date to the date of actual payment at the Interest
        Rate.

ALLOCATION OF THE PURCHASE PRICE

4.20.   The parties have agreed a provisional allocation of the Purchase Price
        which is as shown by the Transaction Breakdown. As soon as practicable
        after all adjustments required to be made under this Clause 4 have
        been determined, the Principal Vendor and the Purchaser shall seek to
        agree (i) a revised allocation of the Purchase Price by allocating
        each adjustment to the Business



                                      13

        Assets or Shares to which it most closely relates and (ii) an
        allocation of the Purchase Price among individual asset categories
        within each jurisdiction on an equitable basis. If they are unable to
        do so within 30 days of the Settlement Date, either party may refer
        the matter for determination to an independent expert and the
        provisions of paragraphs 5 to 11 of Part 2 of Schedule 3 shall (with
        such modifications as may be necessary) apply to such determination.
        The parties agree to adopt the allocation agreed by them or determined
        by the independent expert for all Taxation purposes and shall within
        30 days of such agreement or determination execute a document between
        them adopting such allocation.

4.21.   The parties agree that any changes, pursuant to Clause 4.20 above, to
        be made to the provisional allocation set out in the Transaction
        Breakdown:

        4.21.1. will reflect only the underlying differences between the
                Intra-Group Indebtedness, Third Party Indebtedness, Completion
                Working Capital and Target Companies Cash as compared with the
                Estimated Intra-Group Indebtedness, Estimated Third Party
                Indebtedness, Base Working Capital and Estimated Cash; and

        4.21.2. will adopt the same methodology and practices as were used in
                preparing such provisional allocation.

        If the aggregate amount of the Deferred Consideration payable to the
        Principal Vendor is different from that assumed by the Transaction
        Breakdown, the difference will be allocated wholly as to goodwill in
        the United Kingdom. If the aggregate amount of Consideration Shares
        issued to the Principal Vendor or its nominee or designee is different
        from that assumed by the Transaction Breakdown, the difference will be
        allocated wholly to goodwill in the United States.

4.22.   If any further payment (other than interest under Clause 19.17) is
        made by a party to another party under this Agreement (whether as
        damages for breach or under an indemnity or covenant to pay or as
        Deferred Consideration), such payment shall so far as possible be made
        by way of further adjustment to the Purchase Price and such further
        adjustment shall be allocated as the parties may agree (or as
        determined by an independent expert) on the same basis as is set out
        in Clause 4.20 and Clause 4.21.

DELAYED COMPLETION

4.23.   The parties agree that in the event that prior to the Completion Date:

        4.23.1. clearance from the Spanish Servicio de Defensa de la
                Competencia (the "Spanish Authority") is not obtained; and

        4.23.2. a waiver from suspension by the Spanish Authority is not
                granted,

        (the satisfaction of Clause 4.23.1 or 4.23.2, the "Spanish
        Condition"), all references in this Agreement to "Completion" shall be
        deemed to exclude the transfer of any Business Assets and any portion
        of the Target Businesses, and the assumption



                                      14

        of any Business Liabilities, attributable primarily to the Operations
        located in Spain or otherwise constituting the Operations in Spain
        (together, the "Spanish Operations"). In such event, Completion shall
        occur on the Completion Date as otherwise contemplated by this
        Agreement, except that:

        4.23.3. the number of Completion Consideration Shares issuable at
                Completion under Clause 4.1.2 shall be reduced by the number
                of Spanish Consideration Shares; and

        4.23.4. a delayed completion (the "Delayed Completion") shall take
                place at the offices of the Vendors' Solicitors on the date
                which is five Business Days after the date on which the
                Spanish Condition is satisfied, or at such other place or date
                as may be agreed in writing between the Purchaser and the
                Principal Vendor (such date, the "Delayed Completion Date").

4.24.   In the event that a Delayed Completion is required under Clause 4.23,
        for purposes of determining the amount payable under Clause 4.5 or
        Clause 4.6, as applicable, the Base Working Capital shall exclude the
        Base Spanish Working Capital and the Completion Working Capital shall
        exclude the Completion Spanish Working Capital. The provisions of
        Schedule 3 shall apply to the determination of the Completion Spanish
        Working Capital Statement, mutatis mutandis.

4.25.   On the Delayed Completion Date, the Purchaser shall deliver to the US
        Business Vendor a certificate or certificates representing the Spanish
        Consideration Shares, which shall be in definitive form and registered
        in the name of the US Business Vendor and in a single certificate or
        in such other denominations as the US Business Vendor shall request
        not later than five Business Days prior to the Delayed Completion
        Date.

4.26.   If the Completion Spanish Working Capital is less than the Base
        Spanish Working Capital, the Principal Vendor shall on the Spanish
        Settlement Date pay to the Purchaser an amount equal to such shortfall
        by way of reduction in the cash component of the Purchase Price.

4.27.     If the Completion Spanish Working Capital exceeds the Base Spanish
          Working Capital, the Purchaser shall on the Spanish Settlement Date
          pay to the Principal Vendor an amount equal to such excess by way of
          increase in the cash component of the Purchase Price.

4.28.   In the event that a Delayed Completion is required under Clause 4.23:

        4.28.1. during the period between the Completion Date and the Delayed
                Completion Date, the Principal Vendor shall and, so far as it
                is able to do so, shall procure that the Business Vendors in
                relation to the Spanish Operations shall, allow the Purchaser
                and its agents access pursuant to Clause 5.1 as though all
                references therein to the Operations were references to the
                Spanish Operations, and shall and, so far as it is able to do
                so, procure that the Business Vendors in relation to the
                Spanish Operations shall, comply with Clause 5.2 as though all
                references therein to Operations were references to the
                Spanish Operations and all


                                      15

                references therein to Business Assets (or components thereof)
                were references to Business Assets of the Spanish Operations;
                provided that the Principal Vendor shall not be liable to the
                Purchaser for breach of this Clause 4.28.1 between the
                Completion Date and the Delayed Completion Date if and to the
                extent the breach arose from:

                (a)     the failure by the Purchaser or a member of the
                        Purchaser's Group to manage the Operations sold at
                        Completion (the "Sold Operations") in a manner
                        consistent with Clause 4.28.4;

                (b)     any act or omission of any member of the management of
                        the Sold Operations taken after the Completion Date
                        with respect to the Sold Operations;

                (c)     any member of the management of the Spanish Operations
                        complying with an instruction given by management of
                        the Sold Operations after the Completion Date; or

                (d)     any member of the management of the Spanish Operations
                        disregarding any specific instruction of the Principal
                        Vendor as a result of complying with a specific
                        instruction given by management of the Sold Operations
                        or the Purchaser's Group after the Completion Date;

        4.28.2. the Purchaser or a Local Purchaser will enter into the Supply
                and Distribution Agreement identified as Agreed Form AF15E
                (the "Spanish Distribution Agreement") on the Completion Date;

        4.28.3. the Principal Vendor and the Purchaser will agree upon and put
                in place such financial controls and procedures to ensure that
                the assets, liabilities and operations of the Spanish
                Operations are identifiable;

        4.28.4. the Purchaser and the Principal Vendor shall procure that any
                management services or management support which are required
                for the carrying on of the business of the Spanish Operations

                Completion;

        4.28.5. in respect of any Intellectual Property which has been sold at
                Completion to the Purchaser or a Local Purchaser or is held by
                a Target Company sold at Completion and is required by the
                Spanish Operations in order to carry on the business of the
                Spanish Operations in the manner in which the Spanish

5.      GAP PERIOD UNDERTAKINGS

5.1.    The Principal Vendor undertakes to procure that, pending Completion
        the Business Vendors in relation to the Operations and the Target
        Companies shall, subject to their right to refuse access on the
        grounds that access would be contrary to any applicable laws or
        regulations, allow the Purchaser and its agents such access during
        normal working hours to the books and records of or relating in whole
        or in part to the Operations which are in the possession or otherwise

                    modifications as may be necessary) apply to such
                    determination;

          5.8.2.    from the Completion Date until such time as such charges
                    are agreed or determined, the charges based on 2003 actual
                    costs (indexed) set out in the current form of the
                    Huddersfield Site Services Agreement shall apply; and

          5.8.3.    the charges as agreed between the Purchaser and the
                    Principal Vendor or as determined shall be applied under
                    the Huddersfield Site Services Agreement with effect from
                    the Completion Date and the parties to the Huddersfield
                    Site Services Agreement shall make such further payment or
                    repayment of charges as is necessary to give effect to

          Completion Date or at such other place or time as may be agreed in
          writing between the Purchaser and the Principal Vendor.

6.2.      On Completion, the parties will comply with their respective
          obligations set out in Schedule 9. Neither party (treating for this
          purpose the Vendors as a single party and the Purchaser and Local
          Purchasers as a single party) shall be obliged to proceed to
          Completion unless the other party is (save as set out below)
          simultaneously ready and able to proceed to Completion. Except as
          required by Clause 4.23, neither party shall be obliged to purchase
          or sell only some of the Shares or the Business Assets.

6.3.      If the provisions of Schedule 9 are not complied with by the
          Principal Vendor or the Vendors or the Purchaser or a Local
          Purchaser in all material respects by or on the date set for
          Completion, the Purchaser, in the case of non-compliance by any
          Vendor, or the Principal Vendor, in the case of non-compliance by
          the Purchaser or a Local Purchaser, shall be entitled (in addition
          to and without prejudice to all other rights or remedies available
          to it including any applicable right to terminate this Agreement in
          its entirety in accordance with Clauses 3.5 and 3.6 and the right to
          claim damages) by written notice to the Principal Vendor or, as the
          case may be, to the Purchaser served on such date:

          6.3.1.    to elect to terminate this Agreement;

          6.3.2.    to effect Completion so far as practicable having regard
                    to the defaults which have occurred; or

          6.3.3.    to fix a new date for Completion (not being less than
                    three nor more than ten Business Days after the agreed
                    date for Completion) in which case the provisions of
                    Schedule 9 shall apply to Completion as so deferred but
                    provided such deferral may only occur once unless
                    otherwise agreed in writing between the Principal Vendor
                    and the Purchaser.

6.4.      The Principal Vendor shall procure that the relevant Vendors, and
          the Purchaser shall enter into or shall procure that the relevant
          Local Purchasers, enter into the relevant Local Agreements at
          Completion. To the extent that the provisions of this Agreement are
          inconsistent with or additional to the provisions of any Local
          Agreement, the provisions of this Agreement shall prevail and the
          Principal Vendor and the Purchaser shall procure that the provisions
          of the relevant Local Agreement are adjusted, so far as permissible
          under the laws of the relevant jurisdiction, to the extent necessary
          to give effect to the provisions of this Agreement and/or that the
          relevant Vendor and the Purchaser or the relevant Local Purchaser
          comply with the provisions of this Agreement as though they were
          bound by such provisions in place of the provisions of the relevant
          Local Agreement.

6.5.      If there is an adjustment to the Purchase Price (or the payments
          made on account of the Purchase Price at Completion) under Clause 4
          which is allocated to any part of the Shares, Business Assets or
          Business Liabilities which is the subject of a Local Agreement, the
          Principal Vendor and the Purchaser will procure that the parties to
          such Local Agreement enter into a supplemental agreement reflecting
          such adjustment, if appropriate.


                                      24

6.6.      The Purchaser shall not, and shall procure that no Local Purchaser
          shall, bring any claim against a Vendor in respect of or based upon
          the Local Agreements (nor any warranties, representations or other
          obligations implied or imposed by law) save to the extent necessary
          to implement any legal transfer of shares or assets agreed to be
          sold hereunder in a manner consistent with the terms provided for by
          this Agreement. To the extent that the Purchaser or any relevant
          Local Purchaser does bring a claim (save as referred to above) the
          Purchaser shall indemnify the Vendors against all Losses which any
          Vendor may suffer through or arising from the bringing of such a
          claim against it.

6.7.      The Principal Vendor shall not, and shall procure that no Vendor
          shall, bring any claim against the Purchaser or any relevant Local
          Purchaser in respect of or based upon the Local Agreements (nor any
          warranties, representations or other obligations implied or imposed
          by law) save to the extent necessary to implement any legal transfer
          of shares or assets sold hereunder in a manner consistent with the
          terms provided for by this Agreement. To the extent that any Vendor
          does bring a claim (save as referred to above), the Principal Vendor
          shall indemnify the Purchaser and each relevant Local Purchaser
          against all Losses which it may suffer through or arising from the
          bringing of such a claim against it.

7.       WARRANTIES AND LIMITATIONS

7.1.      In consideration of the Purchaser entering into this Agreement the
          Principal Vendor warrants on behalf of itself and the UK Business
          Vendor to the Purchaser on behalf of itself and each Local Purchaser
          (but on the basis that only the Purchaser shall be entitled to
          enforce the rights, if any, of the Local Purchasers on their behalf)
          that each of the Warranties is true and accurate as at the date of
          this Agreement (as qualified by the matters fairly disclosed in or
          by the Disclosure Letter) and each of the Warranties will be true
          and accurate (as so qualified) on the Completion Date and each of
          the Warranties set out in paragraph 21 of Schedule 4 shall be true
          and accurate on the date of issue of any Consideration Shares. The
          Principal Vendor and the UK Business Vendor acknowledge that the
          Purchaser is entering into this Agreement in reliance on the
          Warranties (as so qualified) and acknowledges and agrees that the
          Warranties are not subject to or limited by any disclosures which
          are not fairly made in or by the Disclosure Letter. In the event of
          a Delayed Completion pursuant to Clause 4.23, and in consideration
          of the Purchaser entering into this Agreement, the Principal Vendor
          warrants on behalf of itself and the UK Business Vendor to the
          Purchaser on behalf of itself and any Local Purchaser of the Spanish
          Operations (but on the basis that only the Purchaser shall be
          entitled to enforce the rights, if any, of such Local Purchaser on
          its behalf) that each of the Warranties will be true and accurate on
          the Delayed Completion Date insofar as they relate to the Spanish
          Operations.

7.2.      As between the Purchaser and the Vendors, the Purchaser undertakes
          that it has relied only on the Warranties (as qualified by the
          matters fairly disclosed in or by the Disclosure Letter),
          indemnities and undertakings in this Agreement and the other
          agreements to be entered into with any Vendor at Completion and not
          on any statements or expressions of opinion or forecasts or
          projections of future performance, nor any other warrantie or
          representatins, indemnities



                                      25

          or undertakings of the Principal Vendor. The Purchaser further
          undertakes that it has not relied upon any other warranties,
          statements, representations or undertakings of any description given
          by the Principal Vendor, any other member of the Vendors' Group or
          any of the officers, employees, solicitors, accountants, other
          agents or professional advisers of any member of the Vendors' Group.

7.3.      The provisions of Schedule 5 shall have effect to regulate and limit
          the Principal Vendor's and the UK Business Vendor's liability for
          breach of the Warranties. Where expressly provided in Schedule 5, it
          shall also regulate and limit the liability of the Vendors in
          respect of other claims under this Agreement and the other
          agreements to be entered into by the Vendors at Completion.

7.4.      Save as expressly provided otherwise, the Warranties shall be
          separate and independent and shall not be limited by reference to
          any other Warranties. The Warranties shall not be extinguished or
          affected by Completion. Without limiting the Purchaser's rights to
          claim for breaches of Warranties under this Agreement, the Purchaser
          shall be entitled to claim after Completion in respect of any breach
          of Warranty of which it becomes aware between the date of this
          Agreement and Completion.

7.5.      Where a Warranty is expressed to be given "so far as the Principal
          Vendor is aware", or is otherwise limited by words to that effect,
          the Principal Vendor and the UK Business Vendor shall be deemed to
          have knowledge only of the matters within the actual awareness of
          the following individuals:

7.6.      Save in the case of fraud, the Principal Vendor and the UK Business
          Vendor undertake not to make any claim against any Employee of the
          Operations or any Target Company on whom it may have relied before
          entering into any terms of this Agreement or the documents to be
          entered into pursuant to this Agreement or in the preparation of the
          Disclosure Letter (but this shall not preclude the Principal Vendor
          from claiming against any other Vendor under any right of
          contribution or indemnity to which it may be entitled). No right to
          damages or compensation shall arise in favour of the Purchaser to
          the extent that events occurring between the Completion Date and the
          Delayed Completion Date, if any, occurred as a result of (i) the
          failure by the Purchaser or a member of the Purchaser's Group to
          manage the Sold Operations (as defined in Clause 4.28.1) in a manner
          consistent with Clause 4.28.4, (ii) any act or omission of any
          member of the management of the Sold Operations taken after the
          Completion Date with respect to the Sold Operations, (iii) any
          member of the management of the Spanish Operations complying with an
          instruction given by management of the Sold Operations after the
          Completion Date or (iv) any member of the management of the Spanish
          Operations disregarding any specific instruction of the Principal
          Vendor as a result of complying with a specific instruction given by
          management of the Sold Operations or the Purchaser's Group after the
          Completion Date.

7.7.      The Purchaser warrants and undertakes to the Vendors that each of
          the warranties set out in this Clause 7.7 is true and accurate as at
          the date of this Agreement and that each of such warranties will be
          true and accurate on the Completion Date by reference to the facts
          and circumstances then subsisting:

          7.7.1.    the Purchaser is and each Local Purchaser is or will on
                    Completion be a company duly incorporated and validly
                    existing under its respective laws of incorporation;

          7.7.2.    the Purchaser has and each Local Purchaser will at
                    Completion have, the corporate power and authority to
                    enter into and perform such of this Agreement and any
                    other documents to be entered into pursuant to this
                    Agreement;

          7.7.3.    this Agreement constitutes, and the documents to be
                    entered into by the Purchaser or the Local Purchasers
                    pursuant to this Agreement when executed will constitute,
                    valid and binding obligations of the Purchaser and the
                    Local Purchasers, as applicable, in accordance with their
                    respective terms;

          7.7.4.    the execution and delivery of and the performance by the
                    Purchaser and each Local Purchaser of its obligations, as
                    applicable, under such of this Agreement and any other
                    documents to be delivered



                                      27

                    pursuant to this Agreement as are relevant to the
                    Purchaser or such Local Purchaser will not:

                    (a)       result in a breach of, or constitute a default
                              under, any material instrument to which the
                              Purchaser or the Local Purchaser is a party or
                              by which the Purchaser or the Local Purchaser is
                              bound; or

                    (b)       result in a breach of any order, judgment or
                              decree of or undertaking to any court,
                              governmental agency or regulatory body to which
                              the Purchaser or the Local Purchaser is a party
                              or by which the Purchaser or the Local Purchaser
                              is bound;

          7.7.5.    the execution and delivery of this Agreement and the
                    documents to be delivered under it and the consummation of
                    the transactions contemplated hereby and thereby will not
                    (i) violate, conflict with or result in any breach of any
                    provision of the constitutional documents or by-laws of
                    the Purchaser or a Local Purchaser or (ii) violate,
                    conflict with or result in any breach of any statute, rule
                    or governmental regulation applicable to the Purchaser or
                    the Local Purchaser;

          7.7.6.    no consent, approval, authorisation, declaration of, or
                    notification to, any governmental authority (other than
                    competition notifications in jurisdictions other than the
                    United Kingdom and the United States) is required to be
                    made or obtained by the Purchaser or the Local Purchaser
                    as a condition of the execution or delivery of this
                    Agreement or the documents to be delivered under this
                    Agreement or, save as contemplated by Clause 3.1, the
                    consummation of the transactions contemplated hereby or
                    thereby;

          7.7.7.    the Purchaser has the financial resources required to
                    fulfil its obligations under this Agreement in respect of
                    the payment of the Purchase Price and, to the extent such
                    resources rely on third parties providing finance, the
                    Purchaser has committed facilities available to it which
                    are not subject to any conditions outside the Purchaser's
                    control;

          7.7.8.    the Consideration Shares have been duly authorised for
                    issuance and, when issued pursuant to the provisions of
                    this Agreement, will be validly issued, fully paid and
                    non-assessable;

          7.7.9.    assuming the accuracy of the Warranties of the Principal
                    Vendor set forth in paragraph 21 of Schedule 4, the
                    issuance of the Consideration Shares by the Purchaser in
                    the manner contemplated by this Agreement will be exempt
                    from the registration requirements of the Securities Act
                    by reason of Section 4(2) thereof and will be exempt from
                    the registration or qualification requirements of the laws
                    of any applicable state of the United States; and

          7.7.10.   the Purchaser has timely filed with the SEC all forms,
                    reports, schedules, proxy statements, registration
                    statements and other documents required to be filed by it
                    since 1 January 2003 pursuant to Sections 13(a) and 15(d)
                    of the Exchange Act (the "Purchaser SEC


                                      28

                    Reports"); as of its respective date, each of the
                    Purchaser SEC Reports complied in all material respects
                    with all applicable requirements of Exchange Act and the
                    applicable rules and regulations of the SEC promulgated
                    thereunder, and did not, at the time filed, contain any
                    untrue statement of a material fact or omit to state a
                    material fact required to be stated therein or necessary
                    in order to make the statements therein, in light of the
                    circumstances under which they were made, not misleading.

8.   CLAIMS PROCEDURE

8.1.      If any party to this Agreement (the "Claimant") becomes aware of any
          matter that may give rise to a claim against another party to this
          Agreement (the "Recipient") under this Agreement (other than in
          respect of a breach of a Warranty relating exclusively to Taxation
          (where the claim shall be dealt with in the manner set out in clause
          6 of the Tax Deed)) notice of that fact shall be given to the
          Recipient as soon as reasonably practicable but any failure to give
          such timely notice shall not affect the rights of the Claimant
          except to the extent that the Recipient is prejudiced by such
          failure.

8.2.      Without prejudice to the validity of the claim or alleged claim in
          question and subject to (i) the Claimant being paid all reasonable
          out of pocket costs and expenses and (ii) the Recipient entering
          into such undertakings relating to confidentiality as the Claimant
          may reasonably require), the Claimant shall allow, and shall procure
          that the relevant Associated Companies of the Claimant allow, the
          Recipient and its accountants and professional advisers to
          investigate the matter or circumstance alleged to give rise to such
          claim and whether and to what extent any amount is payable in
          respect of such claim and for such purpose the Claimant shall give,
          and shall procure that the relevant Associated Companies of the
          Claimant shall give, all such information and assistance, including
          access to premises and personnel, and the right to examine and copy
          or photograph any assets, accounts, documents and records, as the
          Recipient or its accountants or professional advisers may reasonably
          request.

8.3.      If the claim in question is a result of or in connection with a
          claim or liability to a third party then:

          8.3.1.    no admission of liability shall be made by or on behalf of
                    the Claimant or any Associated Company of the Claimant and
                    the claim shall not be compromised, disposed of or settled
                    without the consent of the Recipient (such consent not to
                    be unreasonably withheld or delayed);

          8.3.2.    the Recipient shall (subject to its agreeing that it is
                    liable and providing an indemnity in terms reasonably
                    satisfactory to the Claimant in respect of all costs and
                    expenses which may be incurred by the Claimant or any
                    Associated Company of the Claimant in complying with this
                    Clause 8.3.2) be entitled at its own expense in its
                    absolute discretion to take such action as it shall deem
                    necessary to avoid, dispute, deny, defend, resist, appeal,
                    compromise or contest such claim or liability (including,
                    without limitation, making counterclaims or other claims
                    against third



                                      29

                    parties) in the name of and on behalf of the Claimant or
                    any Associated Company of the Claimant concerned; and

          8.3.3.    the Claimant will give and procure that the relevant
                    Associated Companies of the Claimant give, subject to
                    their being paid all reasonable out of pocket costs and
                    expenses, all such information and assistance, including
                    access to premises and personnel, and the right to examine
                    and copy or photograph any assets, accounts, documents and
                    records, for the purpose of avoiding, disputing, denying,
                    defending, resisting, appealing, compromising or
                    contesting any such claim or liability as the Recipient or
                    their professional advisers reasonably request. The
                    Recipient agrees to keep all such information confidential
                    and only to use it for such purpose.

          This Clause 8.3 will not apply so as to give any of the Vendors any
          rights in respect of the conduct of the defence by the Purchaser, a
          Local Purchaser or a Target Company of claims made by a customer who
          in the twelve months preceding the date of such claim purchased
          goods or services of the Operations. Clause 8.3.2 will not apply as
          to any third party claims seeking an injunction or other relief for
          other than money damages against the Claimant that the Claimant
          reasonably determines, after conferring with its outside counsel,
          cannot be separated from any related claim for money damages. If
          such claim can be separated from any related claim for money
          damages, the Recipient, subject to complying with Clause 8.3.2,
          shall be entitled to assume the defence of the portion relating to
          money damages. The rights of the Recipient under this Clause in
          respect of the negotiation, conduct, defence and settlement of
          claims shall be subject, where applicable, to the rights of the
          Claimant's insurers in respect of such matters.

8.4.      The Purchaser agrees that after the Completion Date, the Purchaser
          will or will procure that a Local Purchaser or a Target Company will
          retain and exert reasonable endeavours to preserve the condition of
          the relevant Books and Records and the books and records of the
          Target Companies and ensure that no such books and records are
          destroyed or disposed of or permitted to be destroyed or disposed of
          during a seven year period from the Completion Date, provided that
          the Purchaser may destroy or dispose of any such books and records
          prior to the expiration of said seven years if the Principal Vendor
          is provided with reasonable advance notice of the Purchaser's
          intention to discard or destroy books and records generally
          identifying the content of the same and the Principal Vendor either
          agrees that such books and records may be destroyed or disposed of
          or fails to make arrangements for the pickup and delivery of such
          documents within thirty days of the date of the Purchaser's notice.

8.5.      The Purchaser and the Principal Vendor undertake to (and shall
          procure that each member of the Purchaser's Group or Vendors' Group
          (as appropriate) shall) take all reasonable steps available to it to
          mitigate any loss suffered by any such party in respect of any claim
          under this Agreement.

8.6.      Where any member of the Purchaser's Group or the Vendors' Group (as
          appropriate) is entitled to recover from some other person any sum
          in



                                      30

          respect of any loss which could give rise or has given rise to any
          claim under this Agreement, the Purchaser or the Principal Vendor
          shall promptly after becoming aware of such entitlement inform the
          Principal Vendor or the Purchaser (as appropriate) of it and will
          procure that there are taken all commercially reasonable steps to
          recover that sum. Any such sum recovered (less any out of pocket
          costs and expenses reasonably incurred in obtaining such recovery)
          will reduce the amount which, without such recovery, could have
          formed the whole or part of any claim under this Agreement provided
          however that such entitled party shall not be obliged to pursue such
          claim against the third party before or in preference to pursuing a
          claim against the other party.

8.7.      If any party pays an amount in discharge of any claim under this
          Agreement and the recipient or one of its Associated Companies
          subsequently recovers from a third party the same losses in respect
          of which the relevant claim was made, the recipient shall repay an
          amount equal to (i) the sum recovered from the third party less any
          out of pocket costs and expenses reasonably incurred in obtaining
          such recovery and less also any Taxation or other deductions
          chargeable or suffered in respect of such sum or (ii) if less, the
          amount previously paid by such party to the recipient.

9.   REGISTRATION RIGHTS

9.1.      For purposes of this Clause 9, the following terms shall have the
          following meanings:

          9.1.1.    "Affiliate" of any person means another person that
                    directly or indirectly, through one or more
                    intermediaries, controls, is controlled by, or is under
                    common control with, such first person; for the purposes
                    of this definition, "control" when used with respect to
                    any person means the possession, directly or indirectly,
                    of the power to direct or cause the direction of the
                    management and policies of a person, whether through the
                    ownership of voting securities, by contract, or otherwise;
                    and the terms "controlling" and "controlled" have meanings
                    correlative to the foregoing;

          9.1.2.    "Common Stock" means the shares of common stock, par value
                    US$1.00 per share, of the Purchaser; and

          9.1.3.    "Rule 144" means Rule 144 promulgated by the SEC under the
                    Securities Act.

9.2.      On and after the date of Completion and until all of the
          Consideration Shares issued under this Agreement may be sold without
          volume limitation under Rule 144 by a person which is not an
          Affiliate of the Purchaser, if the Purchaser proposes to file a
          registration statement with respect to an offering of Common Stock
          to the general public (other than a registration statement on Form
          S-4 or Form S-8 (or any substitute form that may be adopted by the
          SEC)) (any such registration statement, a "Registration Statement"),
          then the Purchaser shall give written notice of such proposed filing
          to the Principal Vendor as soon as practicable (but in no event less
          than 15 Business Days before the anticipated filing date). Upon the
          written request by the Principal Vendor, given within ten


                                      31

          Business Days after delivery of any such notice by the Purchaser, to
          include in such Registration Statement such number of Consideration
          Shares as the Principal Vendor may request, and as are held by the
          Principal Vendor or any member of the Vendors' Group, the Purchaser
          shall include all such Consideration Shares in such Registration
          Statement on the same terms and conditions as the Common Stock
          otherwise being offered and sold pursuant to such Registration
          Statement. Notwithstanding anything contained herein, if the
          Registration Statement is being filed for an underwritten offering
          of Common Stock to the general public for the Purchaser's own
          account (the "Primary Shares"), and the lead underwriter delivers a
          written opinion to the Purchaser that the size of the offering that
          the Purchaser, the Principal Vendor and the holders of any other
          shares proposed to be included in the Registration Statement (the
          "Other Shares") intend to make is such that the success of the
          offering would be materially and adversely affected, then the number
          of Primary Shares, Other Shares and Consideration Shares to be
          included in such offering shall be reduced to the extent necessary
          to reduce the total amount of securities to be included in such
          offering to the amount recommended by such lead underwriter;
          provided that priority shall be (i) first, Primary Shares and (ii)
          second, pro rata among Other Shares and Consideration Shares.
          Notwithstanding the foregoing and for the avoidance of doubt, the
          Purchaser shall be entitled at any time to terminate or abandon any
          registration process and related offering of Common Stock as such
          process relates to all shares included in such registration and
          offering.

9.3.      Whenever the Purchaser is under an obligation pursuant to the
          provisions of this Clause 9 to effect the registration of any
          Consideration Shares, the Purchaser shall, as expeditiously as
          practicable:

          9.3.1.    prepare and file with the SEC such amendments and
                    supplements to the Registration Statement and the
                    prospectus used in connection therewith as may be
                    necessary to keep such Registration Statement effective
                    until the offer and sale of the Common Stock to the
                    general public pursuant to such Registration Statement is
                    complete and to comply with the provisions of the
                    Securities Act with respect to the sale or other
                    disposition of the Consideration Shares;

          9.3.2.    notify the Principal Vendor in writing promptly (i) of the
                    receipt by the Purchaser of any notification with respect
                    to the issuance by the SEC of any stop order suspending
                    the effectiveness of the Registration Statement or
                    prospectus or any amendment or supplement thereto or the
                    initiation or threatening of any proceeding for that
                    purpose and (ii) of the receipt by the Purchaser of any
                    notification with respect to the suspension of the
                    qualification of the Consideration Shares for sale in any
                    jurisdiction or the initiation or threatening of any
                    proceeding for such purpose;

          9.3.3.    furnish to the Principal Vendor such number of copies of a
                    summary prospectus or other prospectus, including a
                    preliminary prospectus, in conformity with the
                    requirements of the Securities Act;


                                      32

          9.3.4.    notify the holders of the Consideration Shares of the
                    happening of any event as a result of which the prospectus
                    included in the Registration Statement, as then in effect,
                    includes an untrue statement of a material fact or omits
                    to state a material fact required to be stated therein or
                    necessary to make the statements therein not misleading in
                    light of the circumstances then existing;

          9.3.5.    list the Consideration Shares on any national securities
                    exchange on which any shares of the Common Stock are
                    listed; and

          9.3.6.    otherwise comply with all applicable rules and regulations
                    of the SEC and make available to its securityholders, as
                    soon as reasonably practicable, earnings statements (which
                    need not be audited) covering a period of 12 months
                    beginning within one month after the effective date of the
                    Registration Statement, which earnings statements shall
                    satisfy the provisions of Section 11(a) of the Securities
                    Act.

9.4.      All fees and expenses incident to the performance of or compliance
          with this Clause 9 by the Purchaser, including all fees and expenses
          of compliance with securities or blue sky laws (including reasonable
          fees and disbursements of counsel in connection with blue sky
          qualifications of the Consideration Shares), printing expenses,
          messenger and delivery expenses, any registration or filing fees
          payable under any US Federal or state securities or blue sky laws,
          the fees and expenses incurred in connection with any listing of the
          securities to be registered on any securities exchange or automated
          quotation system, fees and disbursements of counsel for the
          Purchaser and its independent certified public accountants
          (including the expenses of any comfort letters required by or
          incident to such performance), securities acts liability insurance
          (if the Purchaser elects to obtain such insurance), the reasonable
          fees and expenses of any special experts retained by the Purchaser
          in connection with such registration and the fees and expenses of
          other persons retained by the Purchaser, will be borne by the
          Purchaser; it being understood and agreed that the Principal Vendor
          will bear all fees and expenses incurred by it in connection with
          any registration pursuant to this Clause 9 (including any
          underwriting fees, discounts and commissions, transfer taxes and
          fees and expenses of its counsel).

9.5.      The Purchaser and the Principal Vendor and their Affiliates shall
          reasonably cooperate and use all reasonable endeavours, and shall
          each take all actions reasonably necessary or advisable, in
          connection with the Purchaser's obligation to effect the
          registration of the Consideration Shares with the SEC in accordance
          with this Clause 9.

9.6.      The Purchaser agrees to indemnify and hold harmless, to the fullest
          extent permitted by law, the Principal Vendor, its Affiliates and
          their respective officers, directors, agents, employees and partners
          (each, an "indemnified party") against any and all losses, claims,
          damages, fees, expenses (including reasonable fees, disbursements
          and other charges of counsel and costs of investigation) or other
          liabilities caused by any untrue or alleged untrue statement of
          material fact contained in any Registration Statement, prospectus or
          preliminary prospectus (each as amended and or supplemented, if the



                                      33

          Purchaser shall have furnished any amendments or supplements
          thereto), or any omission or alleged omission to state therein a
          material fact required to be stated therein or necessary to make the
          statements therein (in the case of a prospectus, in the light of the
          circumstances under which they were made) not misleading; provided
          that the Purchaser shall not be required to indemnify any
          indemnified party for any losses, claims, damages, fees, expenses or
          other liabilities resulting from any such untrue statement or
          omission if such untrue statement or omission is made in reliance on
          and in conformity with any information with respect to the Principal
          Vendor or any other indemnified parties furnished in writing to the
          Purchaser by the Principal Vendor or such other indemnified parties
          expressly for use therein.

9.7.      In connection with any registration in which the Principal Vendor or
          any of its Affiliates is participating, the Principal Vendor and its
          Affiliates will furnish to the Purchaser in writing such information
          with respect to the Principal Vendor or its Affiliates as the
          Purchaser reasonably requests for use in connection with any such
          Registration Statement, prospectus, or preliminary prospectus and
          agrees to indemnify the Purchaser, its Affiliates and their
          respective officers, directors, agents, employees and partners to
          the same extent as the foregoing indemnity from the Purchaser to the
          Principal Vendor or its Affiliates, but only with respect to
          information relating to the Principal Vendor or its Affiliates
          furnished to the Purchaser in writing by the Principal Vendor or its
          Affiliates expressly for use in the Registration Statement, the
          prospectus, any amendment or supplement thereto, or any preliminary
          prospectus; provided, however, that the maximum amount of liability
          in respect of such indemnification shall be limited to an amount
          equal to the net proceeds actually received by the Principal Vendor
          or its Affiliates from the sale of Consideration Shares effected
          pursuant to such Registration Statement.

9.8.      In case any proceeding (including any governmental investigation)
          shall be instituted involving any person in respect of which
          indemnity may be sought pursuant to Clause 9.6 or 9.7 above, such
          indemnified party shall promptly notify the person against whom such
          indemnity may be sought (hereinafter in this Clause 9.8 and Clause
          9.9 below called the "indemnifying party") in writing and the
          indemnifying party, upon request of the indemnified party, shall
          retain counsel reasonably satisfactory to the indemnified party to
          represent the indemnified party and any others the indemnifying
          party may designate in such proceeding and shall pay the fees and
          disbursements of such counsel related to such proceeding. In any
          such proceeding, any indemnified party shall have the right to
          retain its own counsel, but the fees and expenses of such counsel
          shall be at the expense of such indemnified party unless (i) the
          indemnifying party and the indemnified party shall have mutually
          agreed to the retention of such counsel or (ii) the named parties to
          any such proceeding (including any impleaded parties) include both
          the indemnifying party and the indemnified party and the indemnified
          party shall have been advised by counsel that representation of both
          parties by the same counsel would be inappropriate due to actual or
          potential differing interests between them. It is understood that
          the indemnifying party shall not, in connection with any proceeding
          or related proceedings in the same jurisdiction, be liable for the
          fees and expenses of more than one separate firm (in addition to any
          local counsel) for all such indemnified parties, and that all such
          fees and expenses shall be


                                      34

          reimbursed as they are incurred. In the case of any such separate
          firm for the indemnified parties, such firm shall be designated in
          writing by the indemnified parties. The indemnifying party shall not
          be liable for any settlement of any proceeding effected without its
          written consent, but if settled with such consent or if there be a
          final judgment for the plaintiff, the indemnifying party agrees to
          indemnify the indemnified party from and against any loss or
          liability by reason of such settlement or judgment. No indemnifying
          party shall, without the prior written consent of the indemnified
          party, effect any settlement of any pending or threatened proceeding
          in respect of which any indemnified party is or could have been a
          party and indemnity could have been sought hereunder by such
          indemnified party, unless such settlement includes an unconditional
          release of such indemnified party from all liability on claims that
          are the subject matter of such proceeding.

9.9.      lf the indemnification provided for in Clause 9.6 or 9.7 above from
          the indemnifying party is unavailable to an indemnified party
          hereunder in respect of any losses, claims, damages, liabilities or
          expenses referred to in Clause 9.6 or 9.7 above, then the
          indemnifying party, in lieu of indemnifying such indemnified party,
          shall contribute to the amount paid or payable by such indemnified
          party as result of such losses, claims, damages, fees, expenses or
          other liabilities in such proportion as is appropriate to reflect
          the relative fault of the indemnifying party and indemnified parties
          in connection with the actions which resulted in such losses,
          claims, damages, fees, expenses or other liabilities, as well as any
          other relevant equitable considerations. The relative fault of such
          indemnifying party and indemnified parties shall be determined by
          reference to, among other things, whether any action in question,
          including any untrue or alleged untrue statement of a material fact
          or omission or alleged omission to state a material fact, has been
          made by, or relates to information supplied by, such indemnifying
          party or indemnified parties, and the parties' relative intent,
          knowledge, access to information and opportunity to correct or
          prevent such action. The amount paid or payable by a party as a
          result of the losses, claims, damages, liabilities and expenses
          referred to above shall be deemed to include, subject to the
          limitations set forth in Clause 9.8 above, any legal or other fees
          or expenses reasonably incurred by such party in connection with any
          investigation or proceeding. The parties hereto agree that it would
          not be just and equitable if contribution pursuant to this Clause
          9.9 were determined by pro rata allocation or by any other method of
          allocation which does not take into account the equitable
          considerations referred to in this Clause 9.9. No person guilty of
          fraudulent misrepresentation (within the meaning of Section 11(f) of
          the Securities Act) shall be entitled to contribution from any
          person who was not guilty of such fraudulent misrepresentation. If
          indemnification is available under Clause 9.6 or 9.7 above, the
          indemnifying parties shall indemnify each indemnified party to the
          full extent provided in Clause 9.6 or 9.7 above without regard to
          the relative fault of said indemnifying party or any other equitable
          consideration provided for in this Clause 9.9. Notwithstanding the
          foregoing, in no event shall the amount contributed by the Principal
          Vendor exceed the aggregate net offering proceeds received by the
          Principal Vendor from the sale of Consideration Shares pursuant to
          the Registration Statement.

10.  CONTRACTS

10.1.     With effect from Completion and to the extent that the same is
          lawful and permissible under the relevant Contract, each of the
          Business Vendors assigns to the Purchaser (or the relevant Local
          Purchaser) its rights under each Contract (other than Excluded
          Assets).

10.2.     To the extent that the assignments referred to in Clause 10.1 are
          not lawful or permissible under a Contract (whether due to the
          consent of the other party or parties to such contract not being
          obtained or otherwise):

          10.2.1.   the Business Vendors shall insofar as required by and at
                    the request of the Purchaser use all reasonable endeavours
                    with the co-operation of the Purchaser to procure such
                    assignments; and

          10.2.2.   until such assignments have been procured:

                    (a)       this Agreement shall not constitute an
                              assignment or attempted assignment of the
                              Contract but the relevant Business Vendors shall
                              hold the relevant Contract in trust for the
                              Purchaser or the relevant Local Purchaser
                              absolutely (but only if the relevant Business
                              Vendor can do so without causing an event of
                              default or termination and without a breach of
                              law);

                    (b)       the relevant Business Vendor shall give all
                              reasonable assistance to the Purchaser to enable
                              the Purchaser to enforce the relevant Business
                              Vendor's rights under the relevant Contract and
                              the Purchaser shall reimburse the relevant
                              Business Vendor for any reasonable out of pocket
                              costs and expenses incurred in giving such
                              assistance but only:

                              (i)       if (x) the Purchaser or the relevant
                                        Local Purchaser receives (either
                                        directly or through the relevant
                                        Business Vendor) the economic claims,
                                        rights and benefits, if any, under
                                        such Contract or (y) the reason why
                                        the Purchaser or the relevant Local
                                        Purchaser does not receive such
                                        economic claims, rights and benefits,
                                        if any, is not the failure of the
                                        relevant Contract to be assigned to
                                        the Purchaser or the relevant Local
                                        Purchaser; and

                              (ii)      to the extent such costs and expenses
                                        do not exceed the costs and expenses
                                        the Purchaser would reasonably have
                                        incurred in enforcing such rights, had
                                        such Contract previously been assigned
                                        to the Purchaser; and

                    (c)       the parties shall co-operate (each at its own
                              expense) in making such other reasonable lawful
                              alternative arrangements regarding the relevant
                              Contract as may best achieve the transfer with
                              effect from Completion of the benefit and burden
                              of such Contract to the Purchaser or a Local
                              Purchaser.


                                      36

10.3.     The Business Vendors will make any benefit received by them under a
          Contract after Completion available to the Purchaser and the
          Purchaser shall procure at its own expense the performance of the
          Business Vendor's obligations under the Contract and shall be
          responsible for the Business Liabilities, if any, arising under or
          relating to such Contract, provided that the Purchaser shall
          (subject to Clause 10.4) only be required to procure the performance
          of such obligations and assume such Business Liabilities to the
          extent it is able (whether directly or through such Business Vendor)
          to receive such benefits and any claims and rights that would
          otherwise have accrued to the Purchaser under such Contract had such
          Contract been assigned to the Purchaser at Completion.

10.4.     In relation to those Contracts under which a Business Vendor has
          outstanding performance obligations as at Completion and where the
          counterparty to such Contract refuses to agree to the effective
          transfer of such performance obligations to the Purchaser, the
          Purchaser shall nonetheless offer to such counterparty to undertake
          such performance obligations in return for the receipt by the
          Purchaser of the economic claims, rights and benefits, if any, under
          such Contract.

11.      EMPLOYEES

The provisions of Schedule 7 shall apply in relation to the Employees and the
transfer of the employment of the Employees (other than the Target Company
Employees) to the Purchaser or a Local Purchaser and ancillary matters.

12.      EMPLOYEE BENEFIT ARRANGEMENTS

The provisions of Schedule 8 shall apply in relation to the Employee Benefit
Arrangements. Where a specific provision of Schedule 8 is inconsistent with
Schedule 7, Schedule 8 shall prevail.

13.      POST-COMPLETION OBLIGATIONS

13.1.     Immediately following Completion the Purchaser shall use all
          reasonable endeavours to procure the release of all securities,
          guarantees and indemnities given by or binding upon any member of
          the Vendors' Group in relation to any debt or obligation of any
          Target Company. Pending such release the Purchaser shall indemnify
          and keep indemnified the Principal Vendor for itself and as trustee

          claims and demands arising out of or in connection with such
          securities, guarantees and indemnities.

13.2.     Immediately following Completion the Principal Vendor shall use all
          reasonable endeavours to procure the release of all securities,
          guarantees and indemnities given by or binding on any Target Company
          in relation to any debt or obligation of any member of the Vendors'
          Group. Pending such release the Principal Vendor shall indemnify and
          keep indemnified the Purchaser for itself and as trustee for the
          Target Companies from and against all costs, claims and demands
          arising out of or in connection with any such securities, guarantees
          and indemnities.

RECEIPTS BY VENDORS' GROUP

13.3.     If at any time after Completion any member of the Vendors' Group

          (less any costs of recovery).

RECEIPTS BY PURCHASER'S GROUP

          reasonably in its power and/or execute and deliver all such further
          documents as such other party may reasonably consider necessary for
          giving full effect to this Agreement (provided that, for the
          avoidance of doubt, if one party requires another to execute a
          document pursuant to this Clause, the party making such request
          shall bear the cost of preparation, execution and, where applicable,
          filing of such document).

          any registered or unregistered trademarks (including any logos or
          other devices) incorporating the Excluded Names. Without prejudice
          to the foregoing, the Purchaser shall procure that within 90 days of
          Completion, any Target Company which has the word "Avecia" as part
          of its corporate name shall effect a change of name so as to exclude
          the word "Avecia" or any confusingly similar word (and the Purchaser
          shall within such 90 day period provide evidence of such change of
          name to the Principal Vendor).

13.7.     The Purchaser, the Local Purchasers and the Target Companies shall
          have the right to continue to use the trade mark "Avecia" or any

          Completion and (ii) on vehicles, stationery, premises, promotional
          material, and on any other assets comprising part of the Business
          Assets or owned by the Target Companies for a period of six months
          from Completion, in each case to which such trade marks were in the
          ordinary course of the Operations affixed before Completion, and
          solely in the manner in which they were being used immediately
          before Completion.

                                      38

          Agreement or any Ancillary Agreement, the Principal Vendor

          will make any claim on any Target Company and the Purchaser
          undertakes that after any Completion no Target Company will make any
          claim on any member of the Vendors' Group, in each case in respect
          of transactions, acts or omissions occurring before Completion other
          than to the extent that the amount claimed was provided for or
          included as an asset or liability in determining the Completion
          Working Capital or reduced the value of an asset therein or was
          included as an Intra-Group Payable or Intra-Group Receivable in the
          Intra-Group Indebtedness Statement.

ASSISTANCE WITH TAX RETURNS AND AUDIT

13.9.     The Purchaser shall procure that the employees of the Purchaser's

          required for the purpose of:

          13.9.1.   completion of Tax Returns of members of the Vendors' Group
                    or Tax Returns of Target Companies which are part of a
                    group for Taxation purposes with members of the Vendors'

                    incorporating information relating to the Target
                    Companies) within all relevant jurisdictions for the tax
                    period up to and including the Completion Date; and

          reasonably required for the purpose of the Purchaser's Group's
          completion of Tax Returns relating to the Operations.

PROCUREMENT OBLIGATIONS

13.11.    Where this Agreement provides for a member of the Vendors' Group or
          a member of the Purchaser's Group to be obliged in any way, such
          provision shall be construed as including an obligation on the
          Principal Vendor or the Purchaser respectively to procure that such
          obligation is discharged. Where this Agreement provides for a member
          of the Vendors' Group or a member of the Purchaser's Group enjoying
          any benefit, such provision shall be construed as including an
          obligation on the Purchaser or the Principal Vendor respectively to
          ensure that such benefit is provided or made available by the
          relevant member of its group.

CONSOLIDATED TAX GROUPS

13.12.    The Principal Vendor and the Purchaser agree that where Target
          Company is a member of a group together with a member of the
          Vendors' Group which makes a consolidated return for any Taxation
          purpose, arrangements shall be


                                      39

          made as soon as practicable to terminate any existing arrangements
          between members of the Vendors' Group and that Target Company.

TRANSFER OF PERMITS

          Purchaser or a Local Purchaser, the Principal Vendor shall or shall
          procure that the relevant member of the Vendors' Group shall at its
          own expense execute such documents as are necessary to effect such
          transfer. Where any Permits of a Business Vendor are not so capable
          of transfer, the Principal Vendor shall and shall procure that the
          relevant members of the Vendors' Group shall offer such assistance
          as the Purchaser may reasonably require for the renewal or reissue
          of such Permit to it or another member of the Purchaser's Group.

CUSTOMERS AND SUPPLIERS

13.14.    After Completion, the relevant Vendors shall, as soon as reasonably
          practicable, join with the Purchaser (or relevant Local Purchaser)

          Principal Vendor to the customers and suppliers and other business
          contacts of the Operations informing them of the transfer of the

          Purchaser or any Vendor discovers that any Business IP is owned by
          any member of the Vendors' Group, the Principal Vendor shall
          promptly procure an assignment of such Intellectual Property to the
          Purchaser (or as directed by the Purchaser) for nominal
          consideration.

ASSISTANCE WITH LITIGATION AND CLAIMS

13.16.    If and to the extent that:

          13.16.1.  the Vendors' Group has under this Agreement retained or
                    the Purchaser's Group has assumed responsibility for any
                    liability or claim; and

          13.16.2.  after Completion the Purchaser's Group or the Vendors'
                    Group, as appropriate (or their respective employees or
                    advisers) have information which would assist in the
                    investigation, defence or settlement of such liability or
                    claims,

          then the Purchaser shall or shall procure that the relevant
          member of the Purchaser's Group shall and the Vendor shall or shall
          procure that the relevant member of the Vendors' Group shall at the
          expense of the party requesting such assistance provide all such

          13.16.4.  making personnel and advisers available for the purpose of
                    taking affidavits and preparation for the attendance of
                    any court hearing or other legal or arbitral or
                    alternative dispute resolution procedures.

          format) the Audited Non-Statutory Accounts, together with an

          the year ended 31st December 2002, in each case in Microsoft Word
          format) prepared in accordance with Item 5 of Form 20-F under the
          Securities Act. The Audited Non-Statutory Accounts shall contain US

          Purchaser with the SEC under Section 13 or 15(d) of the Exchange
          Act.

INTELLECTUAL PROPERTY LICENCES

13.19.    If within the twelve month period following the Completion Date, the
          Purchaser or any Vendor discovers that any Intellectual Property to
          which this Clause 13.19 applies, which Intellectual Property was
          owned by or licensed to a member of the Vendors' Group and was used
          in the Operations in the twelve months preceding the Completion Date
          and such use was material to the Operations in that period, has not
          been assigned or licensed to the Purchaser hereunder or pursuant to
          the Ancillary Agreements, the Principal Vendor shall promptly grant,
          or procure the grant of, a non-exclusive, royalty free, perpetual
          licence to the Purchaser, to use any such Intellectual Property in
          the Target Businesses for the purposes used prior to Completion, but
          for no other purpose whatsoever.

          Where any Intellectual Property to which this Clause 13.19 applies
          is licensed to the Principal Vendor or member of the Vendors' Group,
          the Principal Vendor's only obligation hereunder shall be to grant,
          or procure the grant of, a sub-licence and if such sub-licence
          requires the consent of the licensor, to use its reasonable
          endeavours to obtain such consent.

          Intellectual Property relating to computer software (b) the Excluded
          Names, and (c) any registered or unregistered trade marks including
          any logos or other devices incorporating the Excluded Names.

13.20.    If within the twelve month period following the Completion Date, the
          Purchaser or any Vendor discovers that any Business IP used by any
          member of the Vendors' Group, other than in the Target Businesses,
          in the twelve months preceding the Completion Date and such use was
          material in that period, the Purchaser shall promptly grant, or
          procure the grant of, a non-exclusive, royalty free, perpetual
          licence to the relevant member of the Vendors' Group, to use any
          such Intellectual Property in its business for the purposes used
          prior to Completion, but for no other purpose whatsoever.

INSURANCE POLICIES

13.21.    For so long as any Insured Liabilities remain outstanding, the
          Principal Vendor agrees that it shall not (and will procure that no
          member of the Vendors' Group shall):

          13.21.1.  revoke;

          13.21.2.  take any steps to vitiate or impair the legal validity of;
                    or

          13.21.3.  otherwise take any action which may have the effect of
                    vitiating, or impairing the legal validity of,

          any insurance policy in force at the date of this Agreement
          providing coverage in respect of such Insured Liability.

EMPLOYEE RECORDS

13.22.    The Vendors shall transfer all records and data held by such Vendors
          relating to the Employees (including Sensitive Personal Data (as
          defined in Section 2 of the Data Protection Act 1998) to the extent
          required to comply with TUPE or any other legal requirement but no
          other Sensitive Personal Data) to the Purchaser or a Local Purchaser
          on or as soon as reasonably practicable after Completion. For a
          period of three months from Completion, the Purchaser may request
          that the Vendors notify the Purchaser of any classes of Sensitive
          Personal Data held by the Vendors relating to the Employees (other
          than US Employees) which have not been provided to the Purchaser or
          a Local Purchaser pursuant to this Clause 5.6. The Purchaser may
          then request that the Vendors provide any of such Sensitive Personal
          Data to it (such requested data being "Withheld Sensitive Personal
          Data"). Subject to the Purchaser obtaining all consents from the
          subjects of the Withheld Sensitive Personal Data necessary to allow
          the Vendors to disclose such in compliance with their legal
          obligations, the Vendors shall provide the Withheld Sensitive
          Personal Data to the Purchaser.

14.      GUARANTEES

14.1.     In this Clause:

          14.1.1.   references to the "Guarantor" shall be construed both as a
                    reference to the Purchaser (in relation to the Local
                    Purchasers) and to the Principal Vendor (in relation to
                    the Business Vendors and the Share Vendors); and





                                      42

          14.1.2.   references to the "Guaranteed Subsidiaries" means the
                    Local Purchasers (in relation to the Purchaser) and the
                    Business Vendors and the Share Vendors (in relation to the
                    Principal Vendor).

14.2.     In consideration of the other parties entering into this Agreement
          the Guarantor hereby unconditionally and irrevocably guarantees due
          and punctual performance and observance by the Guaranteed
          Subsidiaries of all their obligations under or for breach of this
          Agreement and any agreement to be entered into pursuant to it
          (including obligations to pay damages) (the "Guaranteed
          Obligations"). The liability of the Guarantor under this Clause
          shall not be released or diminished by any variation of the terms of
          the Guaranteed Obligations, any forbearance, neglect or delay in
          seeking performance of the Guaranteed Obligations or any granting of
          time for such performance, or by any assignment of the benefit of
          the Guaranteed Obligations in accordance with Clause 19.18 or 19.19.

14.3.     If and whenever a Guaranteed Subsidiary defaults for any reason
          whatsoever (and irrespective of the time during which such default
          has been unremedied) in the performance of any of the Guaranteed
          Obligations, the Guarantor shall forthwith upon demand
          unconditionally and irrevocably perform (or procure performance of)
          and satisfy (or procure the satisfaction of) the Guaranteed
          Obligations in regard to which such default has been made.

14.4.     The guarantees in this Clause are to be continuing guarantees and
          accordingly are to remain in force until all the Guaranteed
          Obligations shall have been irrevocably performed or satisfied. Such
          guarantees are in addition to and without prejudice to and not in
          substitution for any rights or security which the recipient of such
          guarantees may now or hereafter have or hold for the performance and
          observance of the Guaranteed Obligations.

14.5.     As a separate and independent stipulation the Guarantor agrees that
          any of the Guaranteed Obligations (including, without limitation,
          any moneys payable) which may not be enforceable against or
          recoverable from any Guaranteed Subsidiary by reason of any legal
          limitation, disability or incapacity on or of the Guaranteed
          Subsidiary or any other fact or circumstance (other than any
          exclusion or limitation imposed by this Agreement or any agreement
          entered into pursuant to this Agreement) shall nevertheless be
          enforceable against and recoverable from the Guarantor as though the
          same had been incurred by the Guarantor and the Guarantor were the
          sole or principal obligor in respect thereof.

14.6.     The guarantees in this Clause shall not be affected or impaired by
          reason of any other fact or event which in the absence of this
          provision would or might constitute or afford a legal or equitable
          discharge or release or a defence to a guarantor.

15.      VAT

15.1.     The parties agree that the consideration given in respect of the
          sale of the Target Businesses, the Business Assets and the sale of
          the Target Companies is exclusive of any amounts in respect of VAT
          which is properly chargeable in respect of such supplies. The
          parties intend, if applicable, that the Target




                                      43


          Businesses and Business Assets shall be sold as a going concern for
          VAT purposes and the Principal Vendor shall (or shall procure that
          the relevant Business Vendor shall) and the Purchaser shall (or
          shall procure that the relevant Local Purchaser shall) give notice
          of such sale to the relevant Tax Authority as required by applicable
          law.

15.2.     The Principal Vendor shall (and shall procure that each Vendor
          shall) and the Purchaser shall and shall procure that each Local
          Purchaser shall preserve any VAT records relating to the Target
          Businesses under their control in such a manner and for such period
          as may be required by applicable law and will allow the other
          parties, upon reasonable notice, reasonable access during working
          hours to and copies at the requesting party's expense of such
          records where reasonably required by such parties for their Taxation
          purposes and will produce information from these records to the
          relevant other parties and/or any relevant Tax Authority if such
          other parties reasonably require it for their Taxation purposes.

15.3.     The Principal Vendor shall (and shall procure that the relevant
          Business Vendors shall) and the Purchaser shall (and shall procure
          that the relevant Local Purchasers shall) use all reasonable
          endeavours (including, for the avoidance of doubt, the making of an
          election or application in respect of VAT to any Tax Authority) to
          secure that the sale of the Business Assets located in the member
          states of the European Community is treated as neither a supply of
          goods nor a supply of services where the country in which the
          Business Assets are located has given effect to Article 5(8) of the
          EEC Sixth Directive (77/388/EEC). The Purchaser warrants that in
          connection with the sale of the Business Assets located in the
          member states of the European Community it (or the relevant Local
          Purchaser) is or will become at the Completion Date a taxable person
          for VAT purposes and that it (or the relevant Local Purchaser) will
          use those Business Assets acquired in carrying on the same kind of
          business (whether or not as part of any existing business) as that
          carried on by the relevant Business Vendors before Completion.

15.4.     To the extent that any state outside the European Community in which
          any of the Business Assets are located provides for relief or
          exemption from VAT on the transfer of a business or treats such a
          transaction as being non-taxable for VAT purposes, the Purchaser and
          the Principal Vendor shall use all reasonable endeavours (including,
          for the avoidance of doubt, the making of an election or application
          in respect of VAT to any Tax Authority) to secure such treatment.

15.5.     The Purchaser shall or shall procure that the relevant Local
          Purchaser shall, subject to the submission by the relevant Vendor of
          a VAT invoice in accordance with the provisions of Clause 19.20, pay
          on Completion or, if later, five Business Days before the relevant
          Vendor is required to account for such VAT the amount of any VAT
          properly payable in any jurisdiction in respect of the transfer of
          any of the Business Assets (whether as a result of denial of a
          relief sought under this Clause 15 or otherwise) in addition to any
          consideration (monetary or non-monetary) expressed in this Agreement
          or in any Local Agreement to be given by the Purchaser or the
          relevant Local Purchaser.


                                      44


15.6.     After Completion the Purchaser or the relevant Local Purchaser shall
          in relation to the Business Assets carry on the same kind of
          business, whether or not as part of any existing business of the
          Purchaser or the relevant Local Purchaser, as the relevant Business
          Vendor carries on with the relevant Business Assets relating to that
          jurisdiction.

16.       THIRD PARTY RIGHTS

          16.1.     Subject to Clause 16.2, this Agreement shall not be
                    enforceable by any person who is not a party to it.

          16.2.     The provisions of Clauses 7.2 and 7.6 may be relied on and
                    enforced by each of the persons or categories of persons
                    referred to in such Clauses.

          16.3.     This Agreement may be amended in accordance with Clauses
                    19.13 and 19.14 without the consent of any person who is
                    not a party to it.

17.       COSTS

Except where expressly provided otherwise, each party shall bear its own costs
in relation to the preparation, negotiation, execution and completion of (and
the performance of their obligations under) this Agreement and the agreements
to be delivered under it. All notarial fees, transfer taxes, stamp duties or
documentary taxes, capital taxes or duties, registration or filing fees or
similar expenses payable in connection with the transactions contemplated by
this Agreement shall be borne by the party legally responsible therefor.

18.       ANNOUNCEMENTS/CONFIDENTIALITY

18.1.     The Principal Vendor and the Purchaser shall, subject to the
          requirements of law or any regulatory body or fiscal authority or
          the rules and regulations of any recognised stock exchange, agree
          together as to the terms of, the timetable for and manner of
          publication of, any formal announcement or circular to the Employees
          or any Vendor's or Target Company's customers, suppliers,
          distributors or sub-contractors which either party may desire or be
          obliged to make regarding this Agreement or the transactions
          contemplated by this Agreement which circular or announcement is
          made or distributed on or prior to the Completion Date. In addition,
          the Purchaser and the Principal Vendor shall consult with each other
          before issuing or making, and provide the other with reasonable
          opportunity to review and make reasonable comment upon, any formal
          announcement or circular to the media which the Purchaser or the
          Principal Vendor may desire or be obliged to make regarding this
          Agreement or the transactions contemplated by this Agreement which
          circular or announcement is made or distributed on or prior to the
          Completion Date.

18.2.     The parties acknowledge that the Confidentiality Agreement shall,
          insofar as it obliges the Purchaser to maintain the confidentiality
          of information relating to the Operations, cease to have any force
          or effect from Completion.

18.3.     Subject to Clause 18.5, the Purchaser shall (and shall procure that
          each member of the Purchaser's Group shall) and the Principal Vendor
          shall (and shall procure that each member of the Vendors' Group
          shall) treat as strictly



                                      45


          confidential and not use or disclose any information received or
          obtained as a result of entering into or performing this Agreement
          (or any other agreement entered into under or pursuant to this
          Agreement) which relates to:

          18.3.1.   the provisions of this Agreement (or any such other
                    agreement);

          18.3.2.   the negotiations relating to this Agreement (and such
                    other agreements); or

          18.3.3.   any other parties and their Associated Companies and the
                    business carried on by each of them.

18.4.     Subject to Clause 18.5, the Principal Vendor shall (and shall
          procure that its Associated Companies shall) treat as strictly
          confidential and not use or disclose any confidential or proprietary

18.5.     The provisions of Clauses 18.3 and 18.4 shall not prohibit
          disclosure or use if and to the extent:

          18.5.1.   required by law or for the purpose of any judicial
                    proceedings arising out of this Agreement or any other
                    agreement entered into under or pursuant to this
                    Agreement;

          18.5.2.   required by the applicable rules of any stock exchange on
                    which the securities of the parties to this Agreement (or
                    one of their Associated Companies) are listed or quoted
                    (or on which it is proposed that such securities be listed
                    or quoted during the process of applying to become so
                    listed or quoted) or any other competent regulatory
                    authority or, in the reasonable opinion of the Purchaser
                    or the Principal Vendor (as appropriate) required to be
                    disclosed to or filed with the SEC to comply with
                    obligations under the Securities Act or the Exchange Act
                    or the rules of the SEC promulgated thereunder;

          18.5.3.   required to vest the full benefit of this Agreement in any
                    party;

          18.5.4.   made to or used on a confidential basis by the
                    professional advisers, auditors and bankers or other
                    funding parties or prospective funding parties of each
                    party or to the extent that disclosure is made to a Tax
                    Authority in connection with the Tax affairs of the
                    disclosing party or a holding company of that party;

          18.5.5.   it becomes publicly available (other than as a result of
                    disclosure by the relevant party to this Agreement or the
                    Confidentiality Agreement, or any other person, in breach
                    of such agreements);

          18.5.6.   that the other parties have given prior written approval
                    to the disclosure;

          18.5.7.   the information is subsequently obtained free of any
                    restrictions on use or obligations of confidentiality from
                    a third party which is itself free of




                                      46

                    any restrictions on use or obligations of confidentiality
                    with respect to that information;

          18.5.8.   the information is already in the possession of that party
                    and is not subject to an obligation of confidentiality or
                    a restriction on use; or

          18.5.9.   the information is independently developed after
                    Completion,

          provided that except where prohibited by any applicable law or
          regulation prior to disclosure of any information pursuant to Clause
          18.5.1the party concerned shall, where possible, promptly notify the
          other party of such requirement with a view to providing the other
          party with the opportunity to contest such disclosure or otherwise
          to agree the timing of, conditions to and content of such
          disclosure.

18.6.     The restrictions contained in this Clause 18 shall continue to apply
          for a period of five years from the Completion Date.

19.       GENERAL

EXCLUSION OF LIMITATIONS ON FRAUD

19.1.     Nothing in this Agreement shall operate to limit the liability of a
          party (or the remedies available to the other party) in respect of a
          fraudulent act or representation by it.

SET-OFF

19.2.     Unless by express agreement between the parties (including set-off
          under Clause 4.10), no amount due and payable by one party to the
          other pursuant to this Agreement shall be set-off against any other
          amount due and payable or alleged to be due and payable by that
          other party to the first party whether pursuant to this Agreement or
          otherwise.

WITHHOLDINGS AND DEDUCTIONS

19.3.     All sums payable by any party to another party under this Agreement
          shall be paid free and clear of all deductions or withholdings, save
          only as may be required by law. If any deductions or withholdings
          are required by law the payer shall (except (i) to the extent the
          same has been taken into account in calculating the amount due under
          any other provision of this Agreement; and/or (ii) in the case of
          interest payable under Clause 19.17) be obliged to pay to the payee
          such sum as will after such deduction or withholding has been made
          leave the payee with the same amount as it would have been entitled
          to receive in the absence of any such requirement to make a
          deduction or withholding.

19.4.     If a recipient of sums payable under this Agreement (other than
          interest payable under Clauses 4.19 or 19.17 and, in the case of the
          Vendors, other than the Purchase Price) is liable for Taxes in
          respect of the such sum the payer shall be obliged to pay to the
          payee such sums as will after the Tax liability has been discharged
          leave the payee with the same amount as it would have been




                                      47

          entitled to receive and to retain in the absence of any such
          requirement to pay Tax in respect of the receipt.

19.5.     If the payee receives a credit for or refund of any Taxation payable
          by it or similar benefit by reason of any deduction or withholding
          for or on account of Taxation described in Clause 19.3, it shall
          reimburse to the payer such part of such additional amounts paid to
          it pursuant to Clause 19.3 above as will leave it (after such
          reimbursement) in no better and no worse position than it would have
          been if the payer had not been required to make such deduction or
          withholding. The payee shall use all reasonable endeavours to obtain
          any available credit, refund or similar benefit and shall where
          possible claim credit or relief from or against its corporate
          profits or similar tax liability in respect of the amount of such
          deduction or withholding as aforesaid in priority to any other
          reliefs or credits available to it. The principles of this Clause
          19.5 shall also apply to Clause 19.4.

19.6.     If any deduction or withholding is made from any payment as
          contemplated in Clause 19.3, the payer shall supply to the payee
          such official receipt, if any, or other evidence of payment to the
          relevant authority of the amount deducted or withheld and shall give
          all reasonable assistance to enable the payee to receive a credit or
          refund or similar benefit by reason of the deduction or withholding
          as promptly as possible.

CERTAIN PAYMENTS TO INCLUDE IRRECOVERABLE VAT

19.7.     Where this Agreement or any contract or agreement entered into in
          performance of this Agreement to which any party to this Agreement
          is a party (each a "Contracting Party") requires any other
          Contracting Party to indemnify, compensate or reimburse another
          Contracting Party for a cost borne by that other Contracting Party,
          or to make a payment to another Contracting Party determined wholly
          or partly by reference to a payment made or cost borne by that other
          party, the amount payable shall be calculated by taking into account
          the underlying cost or payment exclusive of VAT, if any, other than
          irrecoverable VAT.

EFFECT OF COMPLETION

19.8.     The provisions of the Agreement shall remain in full force and
          effect notwithstanding Completion so far as they remain to be
          observed or performed.

ENTIRE AGREEMENT

19.9.     This Agreement contains the whole agreement between the parties
          relating to the subject matter of this Agreement at the date hereof
          to the exclusion of any and all prior proposals, representations,
          agreements and negotiations relating thereto, whether written, oral
          or implied between the parties or any of them and also to the
          exclusion of any terms implied by law which may be excluded by
          contract. THE PURCHASER ACKNOWLEDGES THAT THE OPERATIONS, INCLUDING
          THE TARGET BUSINESSES (WITH THE ASSETS AND LIABILITIES THEREOF)

19.10.    So far as is permitted by law and except in the case of fraud, the
          parties agree and acknowledge that the only right and remedy which
          shall be available to the Purchaser in connection with or arising
          out of or related to any of the statements contained in the
          Warranties shall be damages in contract for breach of this Agreement
          and not rescission of this Agreement, nor damages in tort or under
          statute (whether under the Misrepresentation Act 1967 or otherwise),
          nor any other remedy. The parties agree that irreparable damage may
          occur in the event that any of the provisions of this Agreement were
          not performed in accordance with their specific terms or were

          be entitled to seek an injunction or injunctions to prevent breaches
          of this Agreement and to enforce specifically the terms and
          provisions of this Agreement in any court of England, this being in

          equity.

          permitted by applicable US laws the Purchaser (for itself and on
          behalf of the relevant Local Purchaser) hereby waives compliance by
          the US Business Vendor with the provisions of the bulk sales or
          transfer laws of all applicable jurisdictions within the United

          delivered pursuant to it.

DELAY/FORBEARANCE

19.15.    Except where a specific time limit is specified, no delay or
          forbearance by any party in exercising any right or remedy provided
          by law under or pursuant to this Agreement shall impair such right
          or remedy or operate or be construed as a waiver or variation of it
          or preclude its exercise at any subsequent time and no single or
          partial exercise of any right or remedy shall preclude any other or
          further exercise of it or the exercise of any other right or remedy.
          The rights and remedies of the parties under or pursuant to this
          Agreement are cumulative (provided that no party may make recovery
          more than once in respect of the same loss).

          to fall to be paid on a particular day or date or would have been
          paid on a particular date but for the parties not having agreed the
          amount of the payment or because the parties have required to seek
          the determination of a court, arbitrator, or expert interest shall
          be paid at the Interest Rate by the party due to make the payment of
          principal from the date upon which payment would have been made had
          the payment been agreed or the amount of the required payment been
          known at the earliest point possible under this Agreement until the
          date actually paid. Such interest shall accrue both before and after
          judgment.

ASSIGNMENT

19.18.    Subject to Clause 19.19, this Agreement and the Tax Deed are
          personal to the parties to it. Accordingly, subject to Clause 19.19
          neither the Purchaser or the Local Purchasers nor the Vendors may,
          without the prior written consent of the Principal Vendor (in the
          case of assignment by the Purchaser or a Local Purchaser) or the
          Purchaser (in the case of assignment by a Vendor), assign the
          benefit of all or any of the obligations of any other party under
          this Agreement or the Tax Deed.

19.19.    Except as otherwise expressly provided in this Agreement, either the
          Purchaser or the Local Purchaser or the Vendors may, without the
          consent of the others, assign to an Associated Company the benefit
          of all or any of the other parties' obligations under this Agreement
          and the Tax Deed provided however that if the assignee ceases to be
          an Associated Company of the Principal Vendor, or as the case may be
          the Purchaser, then the Principal Vendor or as the case may be the
          Purchaser shall procure that the assignee re-assigns the benefit of
          the assigned obligations to an Associated Company or to itself (and
          pending such re-assignment, the assigned rights shall be
          unenforceable) and provided further that the maximum liability of
          any party hereunder for breach of any obligation under this
          Agreement or under any covenant or indemnity contained in or entered
          into pursuant to this Agreement shall be limited to the liability
          which would have arisen in the absence of any such assignment.

                                      58

3.3.      CHANGES SINCE ACCOUNTS DATE

          During the period between the Accounts Date and the date of this
          Agreement (inclusive):

          3.3.1.    no Vendor or Target Company has taken any action that, if
                    taken after the date of this Agreement, would constitute a
                    breach of Clause 5.2 (other than Clause 5.2.5 or Clause
                    5.2.9 thereof);

          3.3.2.    the Operations have been carried on in the ordinary course
                    consistent with past practice, without any interruption or
                    alteration in their nature, scope or manner, and so as to
                    maintain the same as a going concern;

          3.3.3.    there has been no Material Adverse Change; and

          3.3.4.    so far as the Principal Vendor is aware, no provision,
                    reserve or accrual in the 2003 Accounts has proved to be
                    materially inadequate in light of subsequent
                    circumstances.

3.4.      UNDISCLOSED LIABILITIES

          The 2003 Accounts properly account in accordance with UK GAAP for
          all liabilities or obligations of any nature which are known to the
          Vendors' Group and which would require to be reflected on a
          consolidated balance sheet as at the Accounts Date or in the notes
          thereto prepared under UK GAAP. Since the Accounts Date, the
          Operations have not incurred any liabilities or obligations other
          than in the ordinary course of the Operations consistent with past
          practice and not in violation of this Agreement.

4.        LEGAL MATTERS

4.1.      COMPLIANCE WITH LAWS

          The Operations have since 30th June 1999 been carried on and are
          being carried on in such manner so that there have been no material
          breaches of applicable laws (including laws concerning the health
          and safety at work of the Employees), legal duties, regulations and
          by-laws in each country in which they are carried on. There is no
          order, decree, decision or judgment of, nor (so far as the Principal
          Vendor is aware) any investigation or inquiry by any court,
          tribunal, arbitrator, governmental agency or regulatory body
          outstanding or anticipated against any Business Vendor or Target
          Company or any person for whose acts or defaults they may be
          vicariously liable which has had or may result in a Material Adverse
          Change, nor has any notice or other communication from any court,
          tribunal, arbitrator, governmental agency or regulatory body been
          received with respect to an alleged material actual or potential
          violation or failure to comply with any such applicable law,
          regulation or by-law.

4.2.      LICENCES AND CONSENTS

          Permits is likely to be suspended, cancelled, refused, modified or

          whether as plaintiff or defendant or other party in any material
          claim, legal action, proceeding suit, litigation, prosecution,
          arbitration or dispute resolution (other than as plaintiff in the
          collection of debts arising in the ordinary course of trading which
          in aggregate do not exceed US$150,000 and in aggregate for any
          particular debtor do not exceed US$10,000) and, so far as the

          resolution. So far as the Principal Vendor is aware, none of the

                              contaminated land or water,

                    circumstances arising since 30th June 1999 that could give
                    rise to any such claim, order or notice.

                    of any of the Properties or otherwise relevant to the
                    Operations since 30th June 1999.

          4.4.4.    The Disclosure Letter contains a list setting out in
                    reasonable detail (i) all claims made by any member of the
                    Vendors' Group or, so far as the Principal Vendor is
                    aware, any third party under the Environmental Deed and
                    (ii) any matters that so far as the Principal Vendor is
                    aware were or should have been the subject of a claim by a
                    member of the Vendors' Group under clause 9.1 of the
                    Environmental Deed.

                    30th June 1999 created or exacerbated any condition at any
                    location or sent waste to an off-site location in
                    connection with any of the Business Properties or the
                    Operations that, in any such case, would (so far as the
                    Principal Vendor is aware) require abatement or clean-up
                    under Environmental Laws or would (so far as the Principal
                    Vendor is aware) subject the Business Vendors or the
                    Target Companies to Liabilities (including third-party

                    reorganisation or similar laws in any jurisdiction
                    concerning any Target Company or Vendor and no events have
                    occurred which, under applicable laws, would justify any

                    been commenced for an administration order to be made (or

          4.5.6.    No event has occurred causing, or which upon instruction
                    or notice by any third party may cause, any floating
                    charge created by any Vendor to crystallise over any
                    Shares or Asset or any charge created by it to become
                    enforceable over any of the Shares or Assets. No such

2.        Subject to paragraph 13, the maximum aggregate liability of the
          Vendors for all claims under this Agreement (other than claims for
          breach of the Specified Warranties) or the documents in the Agreed
          Form AF7, AF12, AF13 (other than AF13A and AF13B), AF15A and the
          Local Agreements shall not exceed 50 per cent of the Purchase Price.

3.        Any claim for breach of Warranties which is made within the time
          limits specified above shall, unless previously satisfied, settled
          or withdrawn, be deemed to be withdrawn and no longer enforceable
          unless legal proceedings in respect thereof are commenced by validly
          issuing and serving legal process within one year of the making of
          such claim provided that in respect of claims in respect of losses
          which remain contingent, the relevant time limit under this
          paragraph 3 shall be one year after such contingency crystallises.

4.        The Principal Vendor and the UK Business Vendor shall not be liable
          in respect of any claim under the Warranties, except for claims
          under the Specified Warranties, to the extent that such claim would
          not have arisen but for a change or changes in law, rules,
          regulation or published administrative practice of any government,
          governmental department agency or regulatory body or legislation
          (whether relating to rates or imposition of Tax or otherwise) made
          after the date of this Agreement.

5.        The Principal Vendor and the UK Business Vendor shall not be liable
          under the Warranties:

          5.1       to the extent that such claim would not have arisen but
                    for or is exacerbated by any voluntary act, omission,
                    transaction or arrangement of the Purchaser or the
                    Purchaser's Group or, after the Completion Date, any
                    Target Company outside the ordinary course of trading;

          5.2       to the extent that such claim would not have arisen but
                    for or is increased by any change in practices or policies
                    of the Target Companies in respect of Taxation after
                    Completion other than one made to comply with standard Tax
                    practices and policies existing at Completion;

          5.3       if and to the extent that such claim would not have arisen
                    but for or is increased by a change of accounting policy,
                    bases or practice of any the Operations after Completion
                    (other than ones effected in order to comply with
                    accounting standards or practices applicable at
                    Completion);

          5.4       to the extent that the claim relates to any losses covered
                    under a policy of insurance in force for the benefit of
                    the Purchaser, the Purchaser's Group or any Target
                    Company;

          5.5       to the extent that the claim arises or is increased as a
                    consequence of the failure of the Purchaser to comply with
                    or to procure the compliance of any Local Purchaser or
                    Target Company with their respective obligations under
                    this Agreement or to act or procure action in accordance
                    with the reasonable instructions of the Principal Vendor
                    or

                    its authorised representative under Clause 8 (Claims
                    Procedure) in respect of that claim;

          5.6       to the extent the matter giving rise to the claim for
                    breach of Warranty was provided for or accrued in the 2003
                    Accounts or the Completion Working Capital Statement; or

          5.7       to the extent such claim arises or is increased as a
                    result of in relation to Taxation any withdrawal of a
                    claim, election, surrender or disclaimer made, or notice
                    or consent in relation to Taxation given after Completion.

6.        The Principal Vendor and the UK Business Vendor shall not be liable
          under the Warranties to the extent the circumstances giving rise to
          or representing the breach of Warranty were fairly disclosed in or
          by the Disclosure Letter or the documents attached to or
          incorporated by reference in the Disclosure Letter.

7.        If in respect of any claim under the Warranties the losses of the
          Purchaser or the Purchaser's Group are contingent only, the
          Principal Vendor and the UK Business Vendor shall not be under any
          obligation to make any payment to the Purchaser until such time as
          the contingent losses cease to be contingent and become actual
          provided always that this paragraph is without prejudice to the
          ability of the Purchaser to notify the claim.

8.        For the avoidance of doubt the amount of any claim for breach of the
          Warranties shall take into account the amount of any Relief (as
          defined in the Tax Deed) and any other corresponding saving or net
          benefit enjoyed by the Purchaser or the Purchaser's Group.

9.        The Purchaser and the Local Purchasers taken together shall not be
          entitled to recover from the Principal Vendor (or any other Vendor)
          under this Agreement or the documents to be entered into pursuant to
          this Agreement more than once in respect of the same losses, and
          accordingly the Principal Vendor and any other Vendor shall not be
          liable under any one such document if and to the extent that the
          losses are or have been recovered under another such document.

10.       As soon as reasonably practicable after a member of the Purchaser's
          Group becomes aware of any matter which may give rise to a claim
          against the Principal Vendor or the UK Business Vendor for breach of
          Warranty, the Purchaser shall give written notice of such matter to
          the Principal Vendor and the UK Business Vendor and shall (then and
          from time to time) take reasonable steps to provide to the Principal
          Vendor and the UK Business Vendor all such information as may be in
          its possession or under its control which is relevant to the
          determination of the Principal Vendor's or the UK Business Vendor's
          liability for such matter provided that any failure to give such
          timely notice or information shall not affect the rights of the
          Purchaser or any member of the Purchaser's Group except to the
          extent the Principal Vendor or the UK Business Vendor is prejudiced
          by such failure.

11.       If the Purchaser has alleged that a breach of any of the Warranties
          has occurred then to the extent that such breach or the effects of
          such breach are capable of being remedied, the Principal Vendor and
          the UK Business Vendor shall be

          afforded an opportunity to effect such remedy within 30 days of its
          receipt of written notice from the Purchaser of such alleged breach.

12.       Notwithstanding any other provision of this Agreement, the Purchaser
          acknowledges that neither the Principal Vendor nor any other member
          of the Vendors' Group nor any of their directors, employees,
          representatives, agents or advisers have given (nor shall they be
          liable in respect of) any warranty, assurance, representation,
          undertaking or covenant relating to any budget or forecast of the
          financial or trading position of the Operations after the date of
          this Agreement or the Completion.

13.       Nothing in this Schedule shall operate to limit the liability of any
          Vendor (or the remedies available to the Purchaser) in respect of a
          fraudulent act or fraudulent misrepresentation by any such Vendor.
