                                       5

GENERALLY

(I)  In consideration for the sale to it (or the relevant Designated Purchaser)
     of the Shares, the Bedford Property, the US Business Assets, the IP Assets
     and the Monoclonal Assets, the Purchaser shall or shall procure that the
     relevant Designated Purchaser shall:

     (i)    pay to the Vendor (on behalf of itself, the Share Sellers, the US
            Business Seller, the IP Assets Sellers and the Monoclonal Assets
            Seller) the Cash Consideration in accordance with the provisions of
            this Agreement; and

     (ii)   discharge and indemnify each member of the Vendor's Group in respect
            of the Assumed Liabilities in accordance with CLAUSE 10 (Assumed
            Liabilities and Retained Liabilities).

(J)  Any Transferring Business Plant and Machinery at a Property which is
     leasehold is sold subject to the rights of the relevant landlord arising
     under the law relating to tenant's fixtures and under the relevant lease.

(K)  For the avoidance of doubt, Part I of the Law of Property (Miscellaneous
     Provisions) Act 1994 shall not apply for the purpose of this CLAUSE 2.

3. CASH CONSIDERATION

(A)  The Cash Consideration payable at Completion for the sale of the Shares,
     the Bedford Property, the US Business Assets, the IP Assets and the
     Monoclonal Assets shall be (pound)49,310,000, which amount shall be payable
     at Completion as to (pound)37,565,613.13 in pounds sterling (the "STERLING
     AMOUNT") and US$17,000,000 in US dollars (the "DOLLAR AMOUNT").

(B)  The Cash Consideration and the assumption by the Purchaser and the relevant
     Designated Purchasers of the Assumed Liabilities pursuant to CLAUSE 10
     (Assumed Liabilities and Retained Liabilities) shall each be exclusive of
     any amount in respect of VAT. If the Cash Consideration or the assumption
     of the Assumed Liabilities is or is deemed to be the consideration for a
     taxable supply for VAT purposes, the Purchaser shall, in addition to the
     Cash Consideration and assumption of the Assumed Liabilities, pay (on
     receipt of a VAT invoice and on behalf of itself and each relevant
     Designated Purchaser) an amount equal to any VAT which may from time to
     time be chargeable in respect of such supply.

(C)  The Cash Consideration shall be allocated between the Shares, the Bedford
     Property, the US Business Assets, the IP Assets and the Monoclonal Assets
     and between the categories of Shares, US Business Assets and Monoclonal
     Assets and between the IP Assets Sellers on the basis set out in SCHEDULE
     12 (Allocation of Cash Consideration) and such allocation shall be adopted
     by the Vendor and the Purchaser, each relevant member of the Vendor's Group
     and each Designated Purchaser for all purposes (including Tax). For US
     federal income Tax purposes such allocation shall be in accordance with
     section 1060 of the Code, and no party shall take any position, in a Tax




                                       6

     return or otherwise, inconsistent with such allocation. For the avoidance
     of doubt, it is understood and agreed that the inclusion of valuations of
     the Shares, the Bedford Property, the US Business Assets, the IP Assets and
     the Monoclonal Assets in SCHEDULE 12 (Allocation of Cash Consideration) is
     not intended to be, and shall not be interpreted as, any Assurance by any
     party as to the assets being transferred or as to the value thereof. The
     Assumed Liabilities which are attributable to the US Business shall be
     allocated to the US Business Assets.

(D)  The Cash Consideration may be adjusted in accordance with the terms of this
     Agreement and/or under the Tax Covenant.

4. FIXED INTRA-GROUP DEBT AMOUNTS

(A)  The Purchaser undertakes that it will, on Completion, procure that each
     relevant Company pays to the relevant member or members of the Vendor's
     Group (as specified in SCHEDULE 13 (Fixed Intra-Group Debt Amounts)) the
     Fixed Intra-Group Debt Amount(s) owing by that Company to such member or
     members of the Vendor's Group. Each payment required by this SUB-CLAUSE (A)
     shall be made:

     (i)    in the currency specified in SCHEDULE 13 (Fixed Intra-Group Debt
            Amounts) in respect of the relevant Fixed Intra-Group Debt Amount;
            and

     (ii)   by telegraphic transfer to the bank account specified by the
            relevant member of the Vendor's Group.

(B)  The Vendor (on behalf of itself and each relevant member of the Vendor's
     Group) undertakes to the Purchaser (on behalf of each of the Companies)
     that payment of the Fixed Intra-Group Debt Amounts pursuant to SUB-CLAUSE
     4(A) shall satisfy and extinguish the liability of the Companies in respect
     of the Fixed Intra-Group Debt Amounts. The Vendor shall procure that each
     relevant member of the Vendor's Group delivers to the Purchaser a duly
     executed receipt in respect of such payment at Completion.

5. WORKING CAPITAL AND VARIABLE INTRA-GROUP DEBT ADJUSTMENTS

(A)  Subject to SUB-CLAUSES (B)AND (C), the Cash Consideration referred to in
     SUB-CLAUSE 3(A) shall be:

     (i)    increased by (pound)1 for every (pound)1 by which the Working
            Capital Amount exceeds the Working Capital Benchmark or, as the case
            may be, reduced by (pound)1 for every (pound)1 by which the Working
            Capital Amount is less than the Working Capital Benchmark; and

     (ii)   reduced by a sum equal to the Variable Intra-Group Debt if the
            Variable Intra-Group Debt reflects a net liability of the Companies
            or, as the case may be, increased by a sum equal to the Variable
            Intra-Group Debt if the Variable Intra-Group Debt reflects a net
            asset of the Companies.

                                       7


     The Cash Consideration referred to in SUB-CLAUSE 3(A) as so adjusted shall
     constitute the "ADJUSTED CASH CONSIDERATION". Any adjustments to the Cash
     Consideration required by this SUB-CLAUSE (A) shall be allocated to the
     greatest extent possible to the particular Shares to which the adjustments
     relate.

(B)  SUB-CLAUSE (A)(i) shall not operate to increase the Cash Consideration
     unless the Working Capital Amount exceeds the Working Capital Benchmark by
     an amount in excess of (pound)250,000 and shall not operate to reduce the
     Cash Consideration unless the Working Capital Amount is less than the
     Working Capital Benchmark by an amount in excess of (pound)250,000. For the
     avoidance of doubt, in either such case the Cash Consideration shall be
     increased or reduced (as appropriate) by the full amount of the difference
     between the Working Capital Amount and the Working Capital Benchmark and
     not merely by the excess of such difference over (pound)250,000.

(C)  The Vendor shall procure that any net liability of the Companies in respect
     of Variable Intra-Group Debt does not exceed the amount of the Cash
     Consideration attributable to the Shares (following any adjustment required
     pursuant to SUB-CLAUSE (A)(i) but before any adjustment is made pursuant to
     SUB-CLAUSE (A)(ii)) and the Vendor shall procure that the indebtedness
     represented by any such excess shall be capitalised by the issue of fully
     paid shares in the relevant Company as soon as reasonably practicable and
     forthwith thereafter the relevant member or members of the Vendor's Group
     shall sell, and the Purchaser shall purchase, or procure the purchase by
     the relevant Designated Purchaser of, the full legal and beneficial
     interest in the shares in the relevant Company arising from such
     capitalisation for a consideration of(pound)1. Such shaRES shall be sold
     free from all liens, charges, equities, encumbrances and other rights
     exercisable by third parties and together with all rights attaching or
     accruing to them as at the date of such transfer.

(D)  As soon as reasonably practicable after and, in any event, within 10
     Business Days of the Completion Accounts, the Variable Intra-Group Debt
     Statement and the Working Capital Benchmark being agreed by the Vendor and
     the Purchaser or (as the case may be) finalised pursuant to CLAUSE 6
     (Completion Accounts and Variable Intra-Group Debt Statement):

     (i)    if the Adjusted Cash Consideration:

            (a) is less than the Cash Consideration referred to in SUB-CLAUSE
                3(A), an amount equal to the shortfall shall be repaid to the
                Purchaser (on behalf of the relevant Designated Purchaser) by
                the Vendor (on behalf of the relevant members of the Vendor's
                Group) by telegraphic transfer to an account notified to the
                Vendor by the Purchaser; or

            (b) is greater than the Cash Consideration referred to in SUB-CLAUSE
                3(A), an amount equal to the excess shall be paid to the Vendor
                (on behalf of the relevant members of the Vendor's Group) by the
                Purchaser (on behalf of the relevant Designated Purchaser) by
                telegraphic transfer to an account notified to the Purchaser by
                the Vendor; and


                                       8


     (ii)   if the Variable Intra-Group Debt:

            (a) reflects a net asset of the Companies, the Vendor shall procure
                that an amount equal to the Variable Intra-Group Debt shall be
                paid to the Purchaser by telegraphic transfer to an account
                notified to the Vendor by the Purchaser; or

            (b) reflects a net liability of the Companies, the Purchaser shall
                procure that an amount equal to the Variable Intra-Group Debt
                shall be paid to the Vendor by telegraphic transfer to an
                account notified to the Purchaser by the Vendor.

     Any amount which a party is required to procure payment of under SUB-CLAUSE
     (D)(ii) shall be set off against any amount owed to such party under
     SUB-CLAUSE (D)(i) so that only a single payment is made by one party to the
     other party in respect of all amounts due under SUB-CLAUSES (D)(i) and
     (D)(ii). As from the Completion Date, no payments (whether of interest or
     principal) shall be made by any member of the Vendor's Group or the
     Purchaser's Group in respect of Variable Intra-Group Debt other than in
     accordance with this SUB-CLAUSE (D) and SUB-CLAUSE (E).

(E)  Any amount paid pursuant to SUB-CLAUSE (D) shall be paid together with a
     supplementary amount computed as if it were interest calculated at (i) the
     Agreed Rate in respect of the period from the Completion Date to the
     earlier of (a) the date of actual payment and (b) the date (the "SETTLEMENT
     DATE") falling 10 Business Days after the day upon which the Completion
     Accounts, the Variable Intra-Group Debt Statement and the Working Capital
     Benchmark are agreed by the Vendor and the Purchaser or, as the case may
     be, determined by the Independent Accountants pursuant to CLAUSE 6
     (Completion Accounts and Variable Intra-Group Debt Statement) and (ii) (if
     the date of actual payment falls after the Settlement Date) at the Default
     Rate in respect of the period from the Settlement Date to the date of
     actual payment. Any supplementary amount payable pursuant to this
     SUB-CLAUSE (E) shall be treated as a further adjustment to the Cash
     Consideration.

(F)  The Vendor (on behalf of each relevant member of the Vendor's Group) and
     the Purchaser (on behalf of each relevant Company) undertake to each other
     that payment of the amounts due under SUB-CLAUSE (D)(ii) (including by way
     of set off) shall satisfy and extinguish all those liabilities of the
     Companies and of the Vendor's Group in respect of the Variable Intra-Group
     Debt. The party receiving payment of such amounts shall receive them on
     behalf of the relevant Companies (in the case of receipt by the Purchaser)
     or, as the case may be, on behalf of the relevant member(s) of the Vendor's
     Group (in the case of receipt by the Vendor). The effect of SUB-CLAUSE
     (D)(ii) and this SUB-CLAUSE (F) shall be that as from the date of payment
     under SUB-CLAUSE (D)(ii):

     (i)    each member of the Vendor's Group which owed to a Company an amount
            included within Variable Intra-Group Debt shall owe that amount
            instead to the Vendor (which will have paid that amount on behalf of
            that member of the Vendor's Group to the Purchaser on behalf of that
            Company) and,


                                       9

            correspondingly, the Purchaser shall owe that amount to the
            Company on whose behalf the Purchaser received it; and

     (ii)   each Company which owed to a member of the Vendor's Group an amount
            included within Variable Intra-Group Debt shall owe that amount
            instead to the Purchaser (which will have paid that amount on behalf
            of that Company to the Vendor on behalf of that member of the
            Vendor's Group) and, correspondingly, the Vendor shall owe that
            amount to the member of the Vendor's Group on whose behalf the
            Vendor received it.

6. COMPLETION ACCOUNTS AND VARIABLE INTRA-GROUP DEBT STATEMENT

(A)  The Purchaser shall procure the preparation of the Completion Accounts and
     the Variable Intra-Group Debt Statement in compliance with the provisions
     of SCHEDULE 10 (Completion Accounts and Variable Intra-Group Debt
     Statement). The Purchaser shall, subject to compliance by the Vendor with
     its obligations under SUB-CLAUSE (F), procure that:

     (i)    the Completion Accounts and the Variable Intra-Group Debt Statement;
            and

     (ii)   a statement of any adjustments which the Purchaser considers should
            be made to the Working Capital Benchmark (the "BENCHMARK STATEMENT")

     are delivered to the Vendor within 40 Business Days of Completion. The only
     grounds upon which the Purchaser shall be entitled to propose adjustments
     to the Working Capital Benchmark are mathematical errors in the computation
     of the Working Capital Benchmark (apparent from PART B of SCHEDULE 10
     (Completion Accounts and Variable Intra-Group Debt Statement) or from
     ATTACHMENT 11) or inconsistency between the basis of preparation of the
     Working Capital Benchmark and the basis of preparation of the Completion
     Accounts as provided for in PART A of SCHEDULE 10 (Completion Accounts and
     Variable Intra-Group Debt Statement), for this purpose substituting 30th
     June 2001 for the Completion Date as the date at which the Working Capital
     Benchmark is prepared. Any Benchmark Statement shall contain an explanation
     (supported, so far as reasonably practicable, by reasonable evidence) of
     the adjustments which the Purchaser considers should be made to the Working
     Capital Benchmark.

(B)  The Vendor shall be entitled at any time within the period expiring 30
     Business Days after receipt of the Completion Accounts, the Variable
     Intra-Group Debt Statement and the Benchmark Statement (if any) to dispute
     the Completion Accounts and/or the Variable Intra-Group Debt Statement
     and/or the proposed adjustments to the Working Capital Benchmark set out in
     the Benchmark Statement by notice in writing (a "DISPUTE NOTICE") to the
     Purchaser setting out, in reasonable detail, the grounds for dispute. The
     only grounds upon which the Vendor shall be entitled to dispute the
     Completion Accounts and/or the Variable Intra-Group Debt Statement are
     mathematical errors in the computation of the Working Capital Amount or
     Variable Intra-Group Debt or a failure by the Purchaser to prepare the
     Completion Accounts and/or the Variable Intra-Group Debt Statement in
     compliance with SCHEDULE 10 (Completion Accounts and Variable Intra-Group
     Debt Statement). The only grounds on which the Vendor shall be entitled to


                                       10



     dispute the proposed adjustments to the Working Capital Benchmark set out
     in the Benchmark Statement are that such proposed adjustments do not comply
     with the provisions of SUB-CLAUSE (A). Any Dispute Notice shall be
     accompanied by a statement (supported, so far as reasonably practicable, by
     reasonable evidence) of the adjustments which the Vendor considers should
     be made to (a) the Completion Accounts and/or the Variable Intra-Group Debt
     Statement, and/or (b) the adjustments to the Working Capital Benchmark set
     out in the Benchmark. If no Dispute Notice is given by the Vendor before
     the expiry of the 30 Business Day period referred to above:

     (i)    the Completion Accounts and the Variable Intra-Group Debt Statement
            shall be deemed to have been agreed by the Vendor and the Purchaser;
            and

     (ii)   the Working Capital Benchmark shall be deemed to have been agreed
            between the Vendor and the Purchaser (on the basis that the proposed
            adjustments set out in the Benchmark Statement are made)

     and, in each case, shall be final and binding on the Vendor and the
     Purchaser. The Vendor shall, if it has not served a Dispute Notice, be
     entitled to notify the Purchaser prior to the expiry of such 30 Business
     Day period that the Completion Accounts, the Variable Intra-Group Debt
     Statement and, if applicable, the Working Capital Benchmark are agreed (in
     the case of the Working Capital Benchmark, on the basis that the proposed
     adjustments set out in the Benchmark Statement are made) and that the
     Vendor does not intend to serve a Dispute Notice and following any such
     notification the Completion Accounts, the Variable Intra-Group Debt
     Statement and, if applicable, the Working Capital Benchmark shall be deemed
     to be agreed by the Vendor and the Purchaser and shall be final and binding
     on the Vendor and the Purchaser.

(C)  The Vendor and the Purchaser shall use all reasonable endeavours to resolve
     any dispute(s) and agree the Completion Accounts, the Variable Intra-Group
     Debt Statement and the Working Capital Benchmark within 30 Business Days of
     the date of receipt of a Dispute Notice by the Purchaser. If the Vendor and
     the Purchaser fail to agree the Completion Accounts, the Variable
     Intra-Group Debt Statement and the Working Capital Benchmark by the expiry
     of the 30 Business Day period referred to above, any matter in dispute may
     be referred by the Vendor or the Purchaser to the Independent Accountants
     (acting as experts and not as arbitrators). For these purposes, the
     "INDEPENDENT ACCOUNTANTS" shall be an independent firm of chartered
     accountants of international repute appointed by the Vendor and the
     Purchaser or, in default of agreement as to such appointment within five
     Business Days of one of them notifying the other of its wish to appoint
     Independent Accountants, by the President for the time being of the
     Institute of Chartered Accountants in England and Wales (or in his absence,
     any appropriate deputy) on the application of either of them.

(D)  (i)    The Independent Accountants shall determine the matters in dispute
            and, providing it is made in accordance with SUB-CLAUSE (D)(ii),
            their decision shall be final and binding on the Vendor and the
            Purchaser in the absence of manifest error (whereupon the relevant
            matter shall be referred back to the Independent Accountants to be
            redetermined). The Vendor and the Purchaser shall be


                                       11

            bound by the terms of reference and timetable agreed with or, in
            default of such agreement, imposed by the Independent
            Accountants.

     (ii)   The only adjustments which the Independent Accountants may determine
            should be made to the Completion Accounts and/or the Variable
            Intra-Group Debt Statement and/or the Working Capital Benchmark are
            adjustments in relation to items to which the Vendor has proposed
            adjustments pursuant to SUB-CLAUSE (B) (in the case of the
            Completion Accounts and the Variable Intra-Group Debt Statement) and
            adjustments proposed in the Benchmark Statement (in the case of the
            Working Capital Benchmark) and any such adjustments shall be:

            (a) in the case of the Completion Accounts and/or the Variable
                Intra-Group Debt Statement, within the range delineated by the
                contents of the Completion Accounts and/or the Variable
                Intra-Group Debt Statement delivered by the Purchaser to the
                Vendor pursuant to SUB-CLAUSE (A) and the adjustments proposed
                by the Vendor pursuant to SUB-CLAUSE (B); and

            (b) in the case of the Working Capital Benchmark, within the range
                delineated by the Working Capital Benchmark as calculated in
                accordance with PARAGRAPH 3 of PART B of SCHEDULE 10 (Completion
                Accounts and Variable Intra-Group Debt Statement) and the
                adjustments proposed in the Benchmark Statement.

(E)  Following settlement of any matter in dispute (whether settled under
     SUB-CLAUSE (C) or (D) or otherwise by agreement between the Vendor and the
     Purchaser), the Completion Accounts, the Variable Intra-Group Debt
     Statement and the Working Capital Benchmark as so settled shall constitute
     the Completion Accounts, the Variable Intra-Group Debt Statement and the
     Working Capital Benchmark for the purposes of this Agreement and shall be
     final and binding on the Vendor and the Purchaser.

(F)  The Vendor shall give the Purchaser and the Purchaser's Accountants, and
     the Vendor shall procure that the members of the Vendor's Group shall give
     the Purchaser and the Purchaser's Accountants, such access to those books,
     records, working papers and employees at the relevant premises of the
     Vendor's Group (or under the control of the Vendor's Group) which the
     Purchaser or the Purchaser's Accountants may reasonably require in
     connection with the preparation and review of the Completion Accounts, the
     Variable Intra-Group Debt Statement and the Benchmark Statement (if any) or
     with the review of any Dispute Notice. Such employees as to whom the
     Purchaser or the Purchaser's Accountants may reasonably require to have
     access shall be instructed to give promptly all such information and
     explanations as the Purchaser or the Purchaser's Accountants may reasonably
     require for these purposes and the Purchaser and the Purchaser's
     Accountants shall be entitled to take photocopies of relevant
     documentation.

(G)  The Purchaser shall give the Vendor and the Vendor's Accountants, and the
     Purchaser shall procure that the members of the Purchaser's Group shall
     give the Vendor and the

                                       12


     Vendor's Accountants, such access to those books, records, working papers
     and employees at the relevant premises of the Purchaser's Group (or under
     the control of the Purchaser's Group) which the Vendor or the Vendor's
     Accountants may reasonably require to review the Completion Accounts, the
     Variable Intra-Group Debt Statement and the Benchmark Statement (if any)
     and to determine whether the Completion Accounts, the Variable Intra-Group
     Debt Statement and the Benchmark Statement (if any) have been prepared in
     accordance with SCHEDULE 10 (Completion Accounts and Variable Intra-Group
     Debt Statement). Such employees as to whom the Vendor or the Vendor's
     Accountants may reasonably require to have access shall be instructed to
     give promptly all such information and explanations as the Vendor or the
     Vendor's Accountants may reasonably require for these purposes and the
     Vendor and the Vendor's Accountants shall be entitled to take photocopies
     of relevant documentation.

(H)  Without limiting any other provision of this Agreement, until the
     Completion Accounts, the Variable Intra-Group Debt Statement and the
     Working Capital Benchmark shall have been agreed by the Vendor and the
     Purchaser or determined by the Independent Accountants, the Vendor and the
     Purchaser shall each keep or cause to be kept proper and accurate records
     of all assets, rights and liabilities which are the subject of the
     Completion Accounts, the Variable Intra-Group Debt Statement and the
     Working Capital Benchmark and each shall allow the Independent Accountants,
     and shall procure that the Independent Accountants are allowed, access to
     books, records, working papers and employees on the basis set out in
     SUB-CLAUSE (F) or (G) (as appropriate). This SUB-CLAUSE (H) does not impose
     on the Purchaser any obligation to create or cause to be created any record
     of the Transferring Business to the extent not in existence at Completion
     and either owned or under the control of a Company or purchased by the
     Purchaser or a Designated Purchaser under this Agreement.

(I)  Each party shall bear its own costs in relation to the preparation,
     determination and review of the Completion Accounts, the Variable
     Intra-Group Debt Statement and (if any) the Benchmark Statement. The Vendor
     shall be responsible for the charges of the Vendor's Accountants and the
     Purchaser shall be responsible for the charges of the Purchaser's
     Accountants. The charges of the Independent Accountants shall be shared
     equally by the Vendor and the Purchaser unless the Independent Accountants
     determine otherwise.

7. COMPLETION

(A)  Completion of the sale and purchase of the Shares, the Bedford Property,
     the US Business Assets, the IP Assets and the Monoclonal Assets shall take
     place (subject, in the case of the Bedford Property, to the provision of
     PART C of SCHEDULE 9 (Properties)) immediately following the execution of
     this Agreement at the offices of Slaughter and May at 4 Coleman Street,
     London EC2 and at such overseas locations as may be agreed between the
     Vendor and the Purchaser.

(B)  At Completion, each of the Vendor and the Purchaser shall do or procure the
     carrying out of all those things listed in respect of it in SCHEDULE 5
     (Completion Arrangements).


                                       13

(C)  Neither the Vendor nor the Purchaser shall be obliged to complete the sale
     and purchase of any of the Shares, the Bedford Property, the US Business
     Assets, the IP Assets or the Monoclonal Assets unless the other (the Vendor
     or the Purchaser as the case may be) shall have complied with its
     obligations under SUB-CLAUSE (B) and SCHEDULE 5 (Completion Arrangements)
     but this SUB-CLAUSE (C) shall not prejudice any other rights or remedies
     available to either party in respect of any default of the other party.

8. THIRD PARTY CONSENTS FOR THE TRANSFER OF THE US BUSINESS ASSETS

(A)  Where any consent or agreement of any third party is required to the
     transfer of any US Business Asset (other than the benefit of a US Contract)
     and such consent or agreement has not been obtained at or before
     Completion, the transfer of the relevant US Business Asset shall not take
     effect, notwithstanding Completion, until that consent or agreement has
     been obtained and the Vendor and the relevant Designated Purchaser shall
     use their respective reasonable endeavours after Completion to obtain it as
     soon as possible.

(B)  No failure to obtain any consent or agreement referred to in SUB-CLAUSE (A)
     and specifically referenced to the Warranty set out in PARAGRAPH 8(E) of
     SCHEDULE 6 (Warranties) as a required consent or agreement in the
     Disclosure Letter shall constitute a breach of any of the Warranties. With
     the exception of the foregoing, the obligations and indemnities set out in
     this CLAUSE 8, section 4(ii) of the US Transfer Agreement and section 2 of
     the US Lease Assignments shall not preclude the Purchaser from making any
     claim and recovery (subject to the provisions of SCHEDULE 7 (Limitation on
     Liability)) under any of the Warranties in respect of any matter relating
     to any of the US Business Assets to the extent that such matter comprises a
     breach, or breaches, of any of the Warranties.

(C)  After Completion, and until such time as any consent or agreement referred
     to in SUB-CLAUSE (A) is obtained, the Vendor shall, or shall procure that
     the relevant member of the Vendor's Group shall:

     (i)    hold the benefit of the relevant US Business Asset referred to in
            SUB-CLAUSE (A) on trust for the relevant Designated Purchaser; and

     (ii)   so far as it lawfully may and subject to (except in respect of any
            Retained Liabilities) the relevant Designated Purchaser indemnifying
            it in respect of any liability, cost, damage or expense which it may
            thereby incur, give all reasonable assistance to the relevant
            Designated Purchaser to enable it to enforce its rights in respect
            of the US Business Asset referred to in SUB-CLAUSE (A).

9. TRANSFER OF US CONTRACTS AND IP LICENCES

(A)  Subject to SUB-CLAUSES (B) and (C), the relevant Designated Purchaser shall
     become entitled to the benefits of the relevant members of the Vendor's
     Group under the US Contracts and the IP Licences with effect from
     Completion and this Agreement shall constitute:




                                       14

     (i)    an assignment by the Vendor (for itself and on behalf of the
            relevant members of the Vendor's Group) of the benefit, subject to
            the burden, of all the IP Licences to the relevant Designated
            Purchaser with effect from Completion; and

     (ii)   an agreement by the Vendor (for itself and on behalf of the relevant
            members of the Vendor's Group) to assign the benefit, subject to the
            burden, of all the US Contracts to the relevant Designated Purchaser
            with effect from Completion. Such assignment of the US Contracts
            shall, subject to SUB-CLAUSES (B) and (C), be effected (in each case
            without prejudice to the obligations of the Vendor set out in this
            SUB-CLAUSE (A)(ii) and the procurement obligation of the Vendor set
            out in SUB-CLAUSE 2(E)) by the US Transfer Agreement or, in the case
            of the leases relating to the US Properties, by the US Lease
            Assignments.

(B)  Where any consent or agreement of any third party is required to enable the
     relevant Designated Purchaser to perform any US Contract or IP Licence
     after Completion or to enable the Vendor or any member of the Vendor's
     Group to transfer, or to procure the transfer of, the benefit or burden of
     any US Contract or IP Licence to the relevant Designated Purchaser, then
     the following provisions shall apply:

     (i)    neither this Agreement nor, to the extent relevant, the US Transfer
            Agreement or the US Lease Assignments shall constitute an assignment
            or an attempted assignment of the relevant US Contract or IP Licence
            if or to the extent that such an assignment or attempted assignment
            would constitute a breach of such US Contract or IP Licence;

     (ii)   after Completion the parties shall use their respective reasonable
            endeavours including, in the case of the Purchaser and without
            limitation, procuring (to the extent permitted by any banking
            covenant to which any member of the Purchaser's Group is subject
            pursuant to the financing arrangements entered, or to be entered,
            into by members of the Purchaser's Group at or about the date hereof
            in order to consummate the transactions contemplated by this
            Agreement) the provision of a guarantee from a member of the
            Purchaser's Group, to obtain the consent or agreement of the
            relevant third party to whatever assignment, transfer, novation or
            other arrangement is necessary to enable the relevant Designated
            Purchaser to assume the burden of and perform any such US Contract
            or IP Licence after Completion and to transfer the benefit of any
            such US Contract or IP Licence to the relevant Designated Purchaser;
            and

     (iii)  after Completion, until the consent or agreement referred to in
            SUB-CLAUSE (B)(ii) is obtained, the relevant Designated Purchaser
            shall, except to the extent that the relevant US Contract or IP
            Licence prohibits it, perform all the obligations of the Vendor or
            the relevant member of the Vendor's Group under such US Contract or
            IP Licence as agent for or sub-contractor to the Vendor or such
            member of the Vendor's Group and shall indemnify each member of the
            Vendor's Group in respect of such performance or, to the extent that
            the relevant US Contract or IP Licence prohibits the relevant
            Designated Purchaser from so acting as agent or sub-contractor or
            the relevant Designated Purchaser


                                       15


            cannot be permitted to act as agent or sub-contractor because of
            confidentiality obligations, the Vendor shall or shall procure that
            a member of the Vendor's Group shall, at the cost of the relevant
            Designated Purchaser and to the extent that the Vendor or the
            relevant member of the Vendor's Group is able, put in place such
            other suitable arrangements in relation to such US Contract or IP
            Licence as the Purchaser may reasonably request or do all such acts
            and things as the relevant Designated Purchaser may reasonably
            require to enable the due performance of the US Contract or IP
            Licence and to provide for the relevant Designated Purchaser the
            benefits (subject as aforesaid to the burdens) of the US Contract or
            IP Licence, and the relevant Designated Purchaser shall indemnify
            each member of the Vendor's Group in respect of all such
            arrangements, acts and things.

(C)  After Completion, and until such time as the consent or agreement referred
     to in SUB-CLAUSE (B) is obtained, the Vendor or the relevant member of the
     Vendor's Group shall be deemed to hold the benefit of the relevant US
     Contract or IP Licence on trust for the relevant Designated Purchaser and,
     so far as it lawfully may and subject to the relevant Designated Purchaser
     indemnifying it in respect of any liability, cost, damage or expense which
     it may thereby incur, shall give all reasonable assistance to the relevant
     Designated Purchaser to enable it to exercise the rights of the relevant
     member of the Vendor's Group so held on trust under the relevant US
     Contract or IP Licence. The foregoing provisions of this SUB-CLAUSE (C)
     shall not apply in relation to any IP Licence if and to the extent they are
     not lawfully permitted in relation to, or not possible without incurring a
     breach of, any term of that IP Licence and, in such circumstances, the
     Vendor shall, or shall procure that the relevant member of the Vendor's
     Group shall, so far as it lawfully may and subject to the relevant
     Designated Purchaser indemnifying it in respect of any liability, cost,
     damage or expense which it may thereby incur, give all reasonable
     assistance to the relevant Designated Purchaser to enable it to exercise
     the rights of the relevant members of the Vendor's Group under that IP
     Licence until such time as the consent or agreement referred to in
     SUB-CLAUSE (B) is obtained.

(D)  Subject to the other provisions of this CLAUSE 9 and to CLAUSE 10 (Assumed
     Liabilities and Retained Liabilities), from the Completion Date the
     relevant Designated Purchasers shall carry out, perform and complete all
     the obligations and liabilities to be performed under the US Contracts and
     the IP Licences.

(E)  As soon as reasonably practicable after the obtaining of the relevant third
     party consent to the transfer of a US Property, the relevant member of the
     Vendor's Group and the relevant Designated Purchaser shall execute the US
     Lease Assignment with respect to that US Property.

(F)  No failure to obtain any consent or agreement referred to in SUB-CLAUSE (B)
     and specifically referenced to the Warranty set out in PARAGRAPH 8(E) of
     SCHEDULE 6 (Warranties) as a required consent or agreement in the
     Disclosure Letter shall constitute a breach of any of the Warranties. With
     the exception of the foregoing, the obligations and indemnities set out in
     this CLAUSE 9, in section 4(ii) of the US Transfer Agreement and in section
     2 of the US Lease Assignments shall not preclude the Purchaser from making
     any claim and recovery (subject to the provisions of SCHEDULE 7


                                       16

     (Limitations on Liability)) under any of the Warranties in respect of any
     matter relating to any of the US Contracts or the IP Licences to the extent
     that such matter comprises a breach, or breaches, of any of the Warranties.

(G)  The provisions of this CLAUSE 9 shall be without prejudice to the
     provisions of CLAUSE 10 (Assumed Liabilities and Retained Liabilities).

10. ASSUMED LIABILITIES AND RETAINED LIABILITIES

(A)  The Purchaser (on behalf of the relevant Designated Purchasers) hereby
     agrees with the Vendor that it will (or will procure that the relevant
     Designated Purchasers will) duly and properly perform, assume, pay and
     discharge when due and indemnify each member of the Vendor's Group against
     all Assumed Liabilities. Without limiting the foregoing, such assumption of
     the Assumed Liabilities shall, insofar as they relate to the US Business or
     the US Business Assets and subject to the remaining provisions of this
     CLAUSE 10, be effected by the US Transfer Agreement and the US Lease
     Assignments. The obligations and indemnities set out in this SUB-CLAUSE
     (A), in section 4(ii) of the US Transfer Agreement and in section 2 of the
     US Lease Assignments shall not preclude the Purchaser from making any claim
     and recovery (subject to the provisions of SCHEDULE 7 (Limitations on
     Liability)) under any of the Warranties in respect of any matter which is
     the subject of the Assumed Liabilities to the extent that such matter
     comprises a breach, or breaches, of any of the Warranties.

(B)  In this Agreement "ASSUMED LIABILITIES" means, subject to SUB-CLAUSES (C),
     (D), (E) and (G), all past (except to the extent satisfied at or prior to
     the signature of this Agreement), present and future liabilities and
     obligations (including, without limitation, contingent liabilities or
     obligations) of the Vendor and each member of the Vendor's Group
     (including, without limitation, for the purposes of sub-paragraph (iii)
     below, Unipath Diagnostics S.A. (France)) of whatsoever nature in respect
     of:

     (i)    the IP Licences;

     (ii)   (other than the marketing, sale or use of Persona products, which
            matters are the subject of (iii) below) the US Business, the US
            Business Assets and the US Contracts, to the extent such liabilities
            and obligations are or have been incurred in the ordinary course of
            the US Business (which liabilities and obligations shall include,
            for the avoidance of doubt and without limitation, the US Assumed
            Litigation);

     (iii)  (subject to the second sentence of CLAUSE 15(F)) any marketing,
            sales or use of Persona products, except to the extent that such
            liabilities and obligations are liabilities and obligations of a
            member of the Vendor's Group domiciled in the United States of
            America. For the avoidance of doubt, nothing in this Agreement shall
            impair, or operate as a waiver of, any right of a member of the
            Vendor's Group (a) to defend any claim in respect of any marketing,
            sales or use of Persona products on the basis that such liabilities
            or obligations are liabilities or obligations of any of the
            Companies, or (b) to recover from any of the Companies in respect of
            any such liabilities or obligations; PROVIDED that no



                                       17

            member of the Vendor's Group domiciled in the United States of
            America shall recover from any of the Companies any exemplary or
            punitive damages in respect of any marketing, sales or use of
            Persona products; and

     (iv)   (save for any Indirect Taxation of the Companies) Indirect Taxation
            to the extent that it is taken into account in calculating the
            Working Capital Amount.

(C)  Notwithstanding SUB-CLAUSES (A) and (B) the Assumed Liabilities shall not
     include the following (the "RETAINED LIABILITIES"):

     (i)    any liability or obligation of the Vendor or any other member of the
            Vendor's Group for or in respect of Taxation (other than in respect
            of Indirect Taxation to the extent that it is taken into account in
            calculating the Working Capital Amount) (a) arising in respect of
            any period of account for Taxation purposes ending on or before
            Completion or, in the case of any Straddle Period, in respect of the
            portion of the Straddle Period ending on Completion, or (b) arising
            in respect of any acts, event or occurrences occurring on or before
            Completion, provided that the Taxation is properly attributable to a
            period specified in (a));

     (ii)   any liability or obligation of the Vendor or any other member of the
            Vendor's Group for or in respect of Intra-Group Trading and Services
            Amounts to the extent that such amounts are US Business Assets or
            are owed by the Vendor or any member of the Vendor's Group at
            Completion to any of the Companies;

     (iii)  any liability or obligation of the Vendor or any other member of the
            Vendor's Group for or in respect of any indebtedness (which, for the
            purposes of this SUB-CLAUSE (C)(iii)) shall exclude amounts which
            are Intra-Group Trading and Services Amounts) incurred in relation
            to the US Business and owing to another member of the Vendor's
            Group;

     (iv)   any exemplary or punitive damages awarded against any member of the
            Vendor's Group (including, without limitation, Unipath Diagnostics
            S.A. (France)) in respect of marketing, sales or use of Persona
            products sold prior to Completion. For the avoidance of doubt,
            nothing in this Agreement shall impair, or operate as a waiver of,
            any right of a member of the Vendor's Group (including, without
            limitation, Unipath Diagnostics S.A. (France)) domiciled outside the
            United States of America (a) to defend any claim in respect of any
            marketing, sales or use of Persona products on the basis that such
            liabilities or obligations are liabilities or obligations of any of
            the Companies, or (b) to recover from any of the Companies in
            respect of any such liabilities or obligations;

     (v)    any liability or obligation of the Vendor or any other member of the
            Vendor's Group in respect of the US Business, any of the US Business
            Assets and/or any of the US Contracts to the extent that such
            liabilities and obligations have been incurred outside the ordinary
            course of the US Business prior to Completion,




                                       18


            other than any other Assumed Liabilities of the type referred to in
            SUB-CLAUSE 10(B) (i), (iii) or (iv);

     (vi)   any liability or obligation of the Vendor or any other member of the
            Vendor's Group in respect of bodily injury to any former employee of
            any member of the Vendor's Group in respect of the US Business or
            any US Employee, in each case arising out of and in the course of
            his employment with the relevant member of the Vendor's Group before
            Completion; and

     (vii)  any liability or obligation of the Vendor or any of the member of
            the Vendor's Group in respect of the US Retained Litigation,

     and the Vendor hereby agrees with the Purchaser that it will, or will
     procure that the appropriate member of the Vendor's Group (including,
     without limitation, Unipath Diagnostics S.A. (France)) will, duly and
     properly perform, assume and pay and discharge when due, and the Vendor
     will indemnify the Purchaser and the other members of the Purchaser's Group
     (other than, save in relation to SUB-CLAUSE (C)(ii), the Companies) against
     all Retained Liabilities.

(D)  Notwithstanding any of the other provisions of this Agreement, the Assumed
     Liabilities shall not include any liability or obligation of the Captive
     Insurer. Accordingly, the provisions of this CLAUSE 10 shall be without
     prejudice to, and neither the Purchaser nor any other member of the
     Purchaser's Group shall assume, or indemnify the Captive Insurer or any
     guarantor of the Captive Insurer in respect of, any liability or obligation
     of the Captive Insurer in relation to the Assumed Liabilities or the
     obligations of the Vendor pursuant to SUB-CLAUSE 15(H)(iv).

(E)  To the extent that the provisions of this CLAUSE 10 would otherwise relate
     to the Employees or the Dutch Sales Staff, the Assumed Liabilities shall
     not extend to or include any liability or obligation of the Vendor or any
     other member of the Vendor's Group in respect of the Employees or the Dutch
     Sales Staff (including, without limitation, in relation to pensions). This
     SUB-CLAUSE (E) is, however, without prejudice to the provisions of CLAUSE
     13 (Employees) and SCHEDULE 8 (Pensions) which shall apply in accordance
     with their terms to the transfer or assumption of any such liability or
     obligation.

(F)  The Purchaser covenants that, at any time and from time to time on or after
     Completion, it will (or will procure that the relevant Designated Purchaser
     will) execute and deliver all such further instruments of assumption and
     acknowledgements or take such other action as the Vendor may reasonably
     request in order to effect the release and discharge in full of any Assumed
     Liability and the assumption of the Assumed Liabilities and the
     substitution of the Purchaser or the relevant Designated Purchaser as the
     primary obligor in respect of the Assumed Liabilities in each case on a
     non-recourse basis to any member of the Vendor's Group other than, for the
     purposes of applicable insurance claims, the Captive Insurer.

(G)  The Vendor (on behalf of itself and each other member of the Vendor's Group
     (including, if applicable and without limitation, Unipath Diagnostics S.A.
     (France)))




                                       19

     shall use reasonable endeavours to mitigate the loss of any member of the
     Vendor's Group (including, without limitation, Unipath Diagnostics S.A.
     (France)) arising from any of the Assumed Liabilities.

(H)  (i)    As soon as reasonably practicable after the Vendor or any member of
            the Vendor's Group receives or otherwise becomes actually aware of
            any assessment, claim, action or demand against it by a third party
            (not being the Purchaser or a member of the Purchaser's Group) or
            any other matter which is reasonably likely to give rise to any
            claim by it under the indemnity set out in SUB-CLAUSE (A) (the
            "ASSUMED LIABILITIES INDEMNITY"), the Vendor shall notify the
            relevant Designated Purchaser in writing of such assessment, claim,
            action or demand. Such notice shall include such details of the
            assessment, claim, action or demand of which the Vendor or any
            member of the Vendor's Group is actually aware (including the
            quantum of such assessment, claim, action or demand, if known) and
            which the Vendor, acting reasonably, considers relevant in order for
            the relevant Designated Purchaser to evaluate the assessment, claim,
            action or demand and whether such assessment, claim, action or
            demand prima facie gives rise to a liability of the Purchaser or the
            relevant Designated Purchaser under the Assumed Liabilities
            Indemnity. Any failure by the Vendor to comply with this
            SUB-PARAGRAPH (H)(i) shall not, for the avoidance of doubt, of
            itself prevent the Vendor or any member of the Vendor's Group from
            making a claim under the Assumed Liabilities Indemnity but neither
            the Purchaser nor the relevant Designated Purchaser shall be liable
            to the Vendor or the relevant member of the Vendor's Group in
            respect of the Assumed Liabilities Indemnity to the extent that the
            amount of the relevant assessment, claim, action or demand
            thereunder is increased, or not reduced, as a result of such
            failure.

     (ii)   Save with respect to the Persona Litigation (in respect of which the
            provisions of SUB-CLAUSE 15(H)(ii) shall apply) and any Indirect
            Taxation taken into account in calculating the Working Capital
            Amount, at the request of the relevant Designated Purchaser and
            subject to:

            (a) the relevant Designated Purchaser first admitting irrevocably
                and unconditionally (subject to the provisions of SUB-CLAUSES
                10(G) and 10(H)(i)) to the Vendor in writing and in a legally
                binding manner its liability under the Assumed Liabilities
                Indemnity in relation thereto; and

            (b) the Purchaser first undertaking in a deed to the Vendor that it
                will indemnify the Vendor and each other member of the Vendor's
                Group (other than the Captive Insurer) against all liabilities,
                costs, damages or expenses incurred by any member of the
                Vendor's Group (other than the Captive Insurer) whether prior
                to, on or after the date of such deed in respect of such
                conduct,

            the Vendor shall allow the relevant Designated Purchaser to take
            conduct as the relevant Designated Purchaser may deem appropriate in
            connection with any such third party assessment, claim, action or
            demand in the name of the



                                       20

            Vendor or the appropriate member of the Vendor's Group (other than
            the Captive Insurer) and in that connection (subject to the
            indemnification as aforesaid) the Vendor:

            (j) shall give, or cause to be given by the relevant members of the
                Vendor's Group (other than the Captive Insurer), to the relevant
                Designated Purchaser all such assistance as the relevant
                Designated Purchaser may reasonably require in avoiding,
                disputing, resisting, settling, defending or appealing any such
                assessment, claim, action or demand including, without
                limitation, such access to the books and records of any member
                of the Vendor's Group, and to the premises and employees and
                professional advisors of the Vendor's Group, during Working
                Hours and on reasonable advance notice, as the Purchaser may
                reasonably require with respect to such third party assessment,
                claim, action or demand;

            (k) shall, and shall procure that each other member of the Vendor's
                Group shall, pass to the relevant Designated Purchaser copies of
                all notices or other documents received by the Vendor or any
                member of the Vendor's Group in relation to the relevant third
                party assessment, claim, action or demand, in each case as soon
                as reasonably practicable after receipt by the Vendor or
                relevant member of the Vendor's Group thereof; and

            (l) shall instruct such legal counsel as the relevant Designated
                Purchaser may nominate to act on behalf of the Vendor or any
                relevant member of the Vendor's Group (other than the Captive
                Insurer), as appropriate, but to act in accordance with the
                relevant Designated Purchaser's instructions,

     provided that no member of the Vendor's Group shall be required to commence
     any legal proceedings where either:

            (y) the Vendor or the relevant member of the Vendor's Group has
                effected a valid legal assignment all of its or their rights in
                relation to the relevant claim to the relevant Designated
                Purchaser; or

            (z) where SUB-CLAUSE (H)(ii)(y) does not apply, the Purchaser or
                relevant Designated Purchaser has not as soon as reasonably
                practicable notified the relevant party against whom such
                proceedings are brought that such proceedings are being brought
                at the instruction of the relevant Designated Purchaser.

     (iii)  The Vendor shall not make (and shall procure that no member of the
            Vendor's Group shall make) any admission of liability, agreement or
            settlement with any third party in relation to any third party
            assessment, claim, action or demand in respect of which the relevant
            Designated Purchaser has admitted its liability and the Purchaser
            has given an undertaking to indemnify the Vendor and the other


                                       21


            members of the Vendor's Group (other than the Captive Insurer), in
            each case in accordance with SUB-CLAUSE (H)(ii), without the prior
            written consent of the relevant Designated Purchaser.

     (iv)   The relevant Designated Purchaser shall be entitled at any stage and
            in its absolute discretion to settle any assessment, claim, action
            or demand in respect of which the relevant Designated Purchaser has
            admitted its liability and the Purchaser has given an undertaking to
            indemnify the Vendor and the other members of the Vendor's Group
            (other than the Captive Insurer), in each case in accordance with
            SUB-CLAUSE (H)(ii).

     (v)    The provisions of SUB-CLAUSES (H) (ii) to (iv) are subject to (i)
            the provisions of any policy of insurance under which the Vendor
            and/or any other member of the Vendor's Group (including, if
            applicable and without limitation, Unipath Diagnostics S.A.
            (France)) and/or any of the Companies makes a claim with respect to
            the assessment, claim, action, demand or other matter giving rise to
            the claim under the Assumed Liabilities Indemnity, and (ii) in such
            case, the directions of the relevant insurer under such insurance
            policy; PROVIDED that the Vendor shall, and shall procure that the
            other members of the Vendor's Group shall, and the Purchaser shall,
            and shall procure that the other members of the Purchaser's Group
            shall, comply with the provisions of SUB-CLAUSES (H)(ii) to (iv) to
            such extent as is permitted under the relevant insurance policy
            under which such a claim is made or as the relevant insurers
            thereunder may otherwise consent.

(I)  The provisions of SUB-CLAUSE 10(H) shall be without prejudice to the
     provisions of CLAUSE 15 (Risk and Insurance).

(J)  The Purchaser (on behalf of the relevant Designated Purchaser) hereby
     agrees with the Vendor that it will duly pay and discharge (or procure to
     be paid and discharged) and indemnify each member of the Vendor's Group
     against all Taxation in respect of or in relation to the Bedford Property,
     the US Business Assets, the IP Assets and the Monoclonal Assets (or their
     use) in respect of (a) any period of account for Taxation purposes
     beginning after Completion or, in the case of any Straddle Period, in
     respect of the portion of the Straddle Period beginning after Completion,
     or (b) arising in respect of any acts, events or occurrences occurring
     after Completion, PROVIDED that the Taxation is properly attributable to a
     period specified in (a) above.

11. INTRA-GROUP TRADING AND SERVICES

(A)  The Purchaser shall procure that each of the Intra-Group Trading and
     Services Amounts which is either an Assumed Liability in respect of the US
     Business or is owed at Completion by any of the Companies to any member of
     the Vendor's Group (in either case, in respect of the period up to
     Completion), together with any interest thereon payable in accordance with
     SUB-CLAUSE (C), is paid to the relevant member of the Vendor's Group to
     whom it is owed:-


                                       22

     (i)    if the relevant parties have agreed in writing a period (not being
            longer than 30 days following Completion) during which the amount
            shall be paid, on or before the end of such period; and

     (ii)   if the relevant parties have not made such an agreement, within 30
            days following Completion.

(B)  The Vendor shall procure that each of the Intra-Group Trading and Services
     Amounts the right to payment of which is a US Business Asset or which is
     owed at Completion by any member of the Vendor's Group to any of the
     Companies (in either case, in respect of the period up to Completion),
     together with any interest thereon payable in accordance with SUB-CLAUSE
     (C), is paid to the relevant Company or the relevant Designated Purchaser
     to whom it is owed:-

     (i)    if the relevant parties have agreed in writing a period (not being
            longer than 30 days following Completion) during which the amounts
            shall be paid, on or before the end of such period; and

     (ii)   if the relevant parties have not made such an agreement, within 30
            days following Completion.

(C)  If a Company, a Designated Purchaser or, as the case may be, a member of
     the Vendor's Group fails to pay any Intra-Group Trading and Services Amount
     within the time allowed for payment under SUB-CLAUSE (A) or SUB-CLAUSE (B)
     (as the case may be) then interest shall be payable thereon by that
     Company, Designated Purchaser or member of the Vendor's Group (as
     appropriate) at the Agreed Rate (accrued daily and compounded monthly) from
     the date on which such amount should have been paid until the actual date
     of payment thereof. For the avoidance of doubt, any interest payable by a
     Company, a Designated Purchaser or, as the case may be, a member of the
     Vendor's Group pursuant to this SUB-CLAUSE (C) shall be in addition to any
     interest included in any Intra-Group Trading and Services Amount.

(D)  All payments referred to in this CLAUSE 11 shall be made in immediately
     available funds without any set-off, restriction or condition and without
     any deduction or withholding (save only as required by law) in such manner
     as is the normal business practice of the relevant payee and in the local
     currency of the relevant payee.

(E)  For the avoidance of doubt:

     (i)    the provisions of this CLAUSE 11 are without prejudice to the
            provisions of CLAUSE 5 (Working Capital and Variable Intra-Group
            Debt Adjustments); and

     (ii)   without prejudice to the provisions of the Transitional Services
            Agreement and with the exception of the Dutch Sales Representation
            Agreement, all agreements and arrangements between any of the
            Companies and members of the Vendor's Group which are in force
            immediately prior to Completion and pursuant to which any of the
            Companies provides or receives services to or from members of the


                                       23

            Vendor's Group or pursuant to which members of the Vendor's Group
            license Intellectual Property to any of the Companies shall be
            terminated with effect from Completion.

12. INTRA-GROUP GUARANTEES AND OTHER AGREEMENTS

(A)  Subject to SUB-CLAUSES (B) and (C), the Purchaser covenants that, at any
     time and from time to time on or after Completion, it will use its
     reasonable endeavours as the Vendor may reasonably request to effect the
     release and discharge in full of any Assurance given by any member of the
     Vendor's Group to any person in respect of any Assumed Liability or any
     obligation or liability of any of the Companies and shall procure the
     assumption of, and the substitution of an appropriate member of the
     Purchaser's Group as the primary obligor in respect of, each such Assurance
     in each case on a non-recourse basis to the members of the Vendor's Group.
     Pending such release and discharge, the Purchaser hereby agrees with the
     Vendor that it will assume and pay and discharge when due, and indemnify
     each member of the Vendor's Group against, all such Assurances.

(B)  The obligations of the Purchaser under SUB-CLAUSE (A) will not apply in
     relation to Assurances which are not disclosed and specifically referenced
     to this clause in the Disclosure Letter ("UNDISCLOSED ASSURANCES"). Subject
     to SUB-CLAUSE (C) the Purchaser acknowledges (on behalf of the Designated
     Purchasers and the Companies) that this CLAUSE 12 shall be without
     prejudice to any rights of subrogation which are available to any member of
     the Vendor's Group in connection with an Undisclosed Assurance.

(C)  The provisions of this CLAUSE 12 shall not apply in respect of any
     Assurance given by the Captive Insurer whether disclosed or not.

(D)  Without prejudice to the generality of SUB-CLAUSE (A), the Purchaser and
     the Vendor will, and the Vendor will procure that Unipath Management
     Limited will, at Completion, enter into a deed of undertaking in the Agreed
     Form (the "DEED OF UNDERTAKING") pursuant to which:

     (i)    Unipath Management Limited will release the guarantee given by the
            Vendor of certain of the obligations assumed by Unipath Limited
            ("UNIPATH'S OBLIGATIONS") under the Business Purchase Agreement
            dated 20th July, 2001 between Unipath Management Limited and Unipath
            Limited (then named, respectively, Unipath Limited and MW Grieg
            Limited) (a copy of which is set out in ATTACHMENT 1); and

     (ii)   the Purchaser will be substituted as the guarantor of Unipath's
            Obligations.

(E)  The Vendor covenants that, at any time and from time to time on or after
     Completion, it will execute and deliver all such instruments of assumption
     and acknowledgements or take such other action as the Purchaser may
     reasonably request (as soon as reasonably practicable following such
     request) in order to effect the release and discharge in full of any
     Assurance given by a Company to any person in respect of any obligation or
     liability of any member of the Vendor's Group (other than an Assumed



                                       24

     Liability), and shall procure the assumption of, and the substitution of an
     appropriate member of the Vendor's Group as the primary obligor in respect
     of, each such Assurance on a non-recourse basis to the Purchaser's Group.
     Pending such release and discharge, the Vendor hereby agrees with the
     Purchaser (on behalf of itself and as trustee for the Companies) that it
     will assume and pay and discharge when due, and indemnify each Company
     against, all such Assurances.

13. EMPLOYEES

ALL EMPLOYEES

(A)  At the request of the Vendor, the Purchaser has provided or will provide
     (as the case may be) the Vendor with all reasonable information which the
     Purchaser has access to, in order to enable the Vendor to comply with any
     obligations to inform, consult or notify any person about the matters
     contemplated by this Agreement in so far as it relates to any Employee to
     the extent required by local law (including, without limitation, the
     Transfer Regulations) and within the relevant time limits imposed by local
     law.

(B)  The provisions of this CLAUSE 13 shall apply to a relevant Employee only
     for so long as he/she continues in the employment of any member of the
     Purchaser's Group, any Company or any person to whom the whole or any
     relevant part of the Transferring Business is transferred. Accordingly, the
     Purchaser shall procure that the acquirer from it or another member of the
     Purchaser's Group of the whole or any part of the Transferring Business or,
     directly or indirectly, the whole or any part of the issued share capital
     of any Company shall honour the obligations of the Purchaser under this
     CLAUSE 13 (including, for the avoidance of doubt, under this SUB-CLAUSE
     (B)) in respect of all Employees concerned in the relevant acquisition or
     transfer.

(C)  The Purchaser agrees with the Vendor that it will indemnify each member of
     the Vendor's Group against any claim relating to the terms and conditions
     of employment or benefits offered to or provided to the Employees in
     connection with their employment (including, without limitation, claims
     relating to the terms and conditions of such employment or benefits and
     termination of such employment or benefits) provided that any such claim
     arises after Completion and is in respect of the period after Completion
     and that any such liability has not arisen due to a breach of this
     Agreement by the Vendor.

(D)  (i)    If the employment of any Employee is terminated within three years
            of the Completion Date the Purchaser shall procure that there shall,
            subject to SUB-CLAUSE (F)(ii) and F(iii), be applied in respect of
            such Employee contractual terms and conditions and those
            non-contractual terms and benefits listed in ATTACHMENT 14 (the
            "NON-CONTRACTUAL BENEFITS") giving due credit to the Employee for
            any additional service or earnings from the Completion Date onwards)
            in such a manner as to be no less favourable than those applicable
            in respect of the particular Employee at the Completion Date and, in
            the case of the US Employees, those set out in ATTACHMENT 12. For
            the avoidance of doubt, nothing in this SUB-CLAUSE (D)(i) shall
            oblige the Purchaser to maintain any contractual term or
            Non-Contractual Benefit applicable to an Employee after the


                                       25

            date of termination of their employment in the event that the
            Purchaser terminates the employment of that Employee within 3 years
            of the Completion Date other than applicable severance payments
            which may be payable on or after termination of employment.

     (ii)   The Purchaser shall procure that, in respect of benefits which are
            provided on the death or disability of an Employee or his spouse,
            child or dependant within the period of three years following the
            Completion Date (other than benefits provided under a Vendor's Group
            Plan or benefits under the Unilever Superannuation Fund (for the
            purposes of this CLAUSE 13, a "GROUP PLAN BENEFIT")), equivalent
            benefits shall be provided on such events which are payable in
            circumstances and under conditions which are not materially less
            favourable to the beneficiary concerned as those which would have
            applied had the death or disability occurred whilst the beneficiary
            was a beneficiary of the arrangement in question under the
            provisions of that arrangement in force immediately prior to the
            Completion Date.

(E)  Without prejudice to SUB-CLAUSE (D), the Purchaser shall procure that for a
     period of three years following the Completion Date Employees who are
     employed shall be employed, subject to SUB-CLAUSES (F)(ii) AND (iii), on
     contractual terms and conditions (including, without limitation, any
     related to length of service but excluding any Group Plan Benefit) and
     shall be granted Non-Contractual Benefits which are no less favourable
     taken as a whole in respect of each Employee than those which apply in
     respect of each Employee at Completion. This undertaking does not
     constitute a guarantee that the Employees will continue to be employed
     following Completion. In addition, in respect of Stephen Pepper, Lisa Link
     and Patricia Nasshorn the Purchaser shall procure that for a period of
     three years following the Completion Date these Employees shall be
     considered for a grant of discretionary share options in the same way as
     any other individual of equivalent seniority employed by the Purchaser or
     any other member of the Purchaser's Group. Further the Purchaser shall, on
     1st July, 2002 or as soon as reasonably practicable thereafter but in any
     event before 31st December, 2002, procure that the Employees shall be
     entitled to join the Purchaser's existing US employee stock purchase plan
     in place as at the date of this Agreement (and any replacement scheme) and
     that the Employees shall be entitled to participate in such scheme for at
     least 3 years following the Completion Date.

(F)  (i)    The Purchaser's agreement to the provisions of SUB-CLAUSES (D) and
            (E) is given by the Purchaser on the express understanding that, if
            the Purchaser is in breach of any such provisions, the Vendor may,
            at its absolute discretion, and without limitation, seek to procure
            compliance with such provisions by the Purchaser by applying to the
            court for damages and/or specific performance.

     (ii)   Notwithstanding SUB-CLAUSE (D)(i) and SUB-CLAUSE (E), the Purchaser
            shall have no obligation in respect of the application of
            Non-Contractual Benefits in connection with the termination of the
            employment of any Employee within three years of the Completion Date
            and shall have no obligation in respect of the Non-Contractual
            Benefits to which any Employee is entitled in the period of



                                       26

            three years following the Completion Date except to the extent that
            such Non-Contractual Benefits are disclosed as set out in ATTACHMENT
            14.

     (iii)  For the avoidance of doubt, the Purchaser shall be entitled, so far
            as is lawful and/or with the consent of the relevant Employee or
            Employees, to vary contractual terms and the Non-Contractual
            Benefits referred to in SUB-CLAUSE (D)(i) or the contractual terms
            and the Non-Contractual Benefits referred to in SUB-CLAUSE (E)
            provided that such variations result in contractual terms and
            non-contractual benefits which are no less favourable, taken as a
            whole in respect of each Employee, than those applicable on the
            Completion Date.

(G)  Without prejudice to the parties' obligations under SUB-CLAUSES (A) to (F),
     each of the parties shall comply with the requirements relating to that
     party set out in Annex B of Part A of SCHEDULE 8 (Pensions).

(H)  For the avoidance of doubt, the provisions of this CLAUSE 13 are without
     prejudice to:

     (i)    the operation of any rule of law in relation to, or contractual term
            of, the terms and conditions of employment of the Employees; and

     (ii)   any provision of SCHEDULE 8 (Pensions).

(I)  If any Employee requires a work permit or employment pass or other approval
     (in this sub-clause, "PERMITS") for his employment to continue for the
     period of three years after the Completion Date the Purchaser undertakes to
     procure that any necessary applications are promptly made and to use its
     reasonable efforts to secure the necessary Permits.

SECONDED EMPLOYEES

(J)  The Vendor shall procure that the relevant member of the Vendor's Group
     shall use its reasonable endeavours to procure that each Seconded Employee
     continues to be employed by a member of the Vendor's Group and is, in the
     case of Peter Welch and Michael Joubert, for the period of 24 months
     following Completion and, in the case of Fiona Humberstone, for the period
     of 12 months following Completion, seconded to work in the Transferring
     Business. For the avoidance of doubt, neither the Vendor nor any other
     member of the Vendor's Group, shall be under any obligation to provide to
     the Purchaser or any member of the Purchaser's Group any replacements for
     the Seconded Employees if either Seconded Employee resigns during his
     period of secondment or upon the death of any Seconded Employee. The Vendor
     shall inform the Purchaser promptly if any Seconded Employee resigns their
     employment with the Vendor's Group during their period of secondment. The
     following additional provisions shall apply with respect to the Seconded
     Employees:

     (i)    Each Seconded Employee shall be paid, and employment benefits shall
            be provided to such Seconded Employee, by a member of the Vendor's
            Group and the Purchaser shall pay to the Vendor (on behalf of the
            relevant member of the Vendor's Group) (in advance) on the twentieth
            Business Day of each calendar


                                       27

            month the direct and indirect cost of salary and other employment
            benefits for that Seconded Employee for such calendar month
            including relevant Taxes, social security costs and any notional or
            unfunded costs or accruals in relation to post-Completion service
            (for example in relation to Group Plan Benefits) together with the
            cost of benefit accrual charge on a local funding basis but ignoring
            any surplus or deficit in the Vendor's Group Plan in question on
            such basis as the Vendor may reasonably determine and agree with the
            Purchaser. To the extent such agreement is not reached, the relevant
            provisions of PARAGRAPH 10 of PART A of SCHEDULE 8 (PENSIONS) shall
            apply. If any payment made pursuant to this SUB-CLAUSE (J)(i) is or
            is deemed to be the consideration for a taxable supply for VAT
            purposes, the Purchaser shall, in addition to such payment, pay (on
            receipt of a VAT invoice) an amount equal to any VAT which may from
            time to time be chargeable in respect of any such supply.

     (ii)   The relevant member of the Vendor's Group may from time to time
            increase the salary benefits of such Seconded Employees; PROVIDED
            that any such increases are in line with increases for similar
            employees of the Vendor's Group.

     (iii)  The Purchaser shall indemnify each member of the Vendor's Group
            against any claim by, or relating to, a Seconded Employee except to
            the extent that such claim arises as a result of acts or omissions
            of the Vendor or any other member of the Vendor's Group. There shall
            be no liability under this SUB-CLAUSE J(iii) to the extent of any
            amount recovered by the Vendor or any other member of the Vendor's
            Group under any policy of employers' liability insurance in respect
            of any such claim by, or relating to, a Seconded Employee and the
            Vendor shall (and shall procure that the other members of the
            Vendor's Group shall) use reasonable endeavours (other than with
            respect to an insurance claim with no reasonable prospect of
            success) to recover under any relevant employees' liability
            insurance policy maintained by any member of the Vendor's Group in
            respect of any such claim by, or relating to, a Seconded Employee.

     (iv)   The Purchaser shall request that each Seconded Employee enters into
            a reasonable standard form confidentiality agreement for the benefit
            of the Purchaser's Group in relation to the confidential information
            which they shall obtain while on secondment and, in the event that
            any Seconded Employee declines to enter into such confidentiality
            agreement, the Purchaser shall, notwithstanding the further
            provisions of this SUB-CLAUSE (J), be entitled to terminate (without
            liability to the Purchaser's Group) the secondment arrangement with
            that Seconded Employee immediately upon written notice to the
            Vendor.

     If, after Completion, the Purchaser does not require the Seconded Employees
     then it shall give the Vendor 3 months' written notice of its wish to
     terminate the arrangements and the Vendor will be responsible for the
     salary and other benefits from the expiry of such notice, and any
     applicable retirement or severance benefits of the relevant Seconded
     Employees.



                                       28


(K)  For the avoidance of doubt, the Seconded Employees shall continue to be
     employed by a member of the Vendor's Group for the period of 24 months and
     12 months (as the case may be) following Completion and this Agreement
     shall not operate to transfer their employment to the Purchaser or any
     other member of the Purchaser's Group during the period of secondment. The
     Vendor agrees that the Purchaser may offer the Seconded Employees
     employment with the Purchaser's Group during the period of secondment and
     that if such offer is accepted by any Seconded Employee the relevant member
     of the Vendor's Group shall release them from their contract of employment.

(L)  For the avoidance of doubt the Purchaser shall have no obligation to employ
     or have seconded to the Purchaser or any other member of the Purchaser's
     Group, Robert Field, Malcolm Smith or Frans van der Ouderaa (the "EXCLUDED
     EMPLOYEES"). Nothing in this agreement shall operate to transfer the
     employment of the Excluded Employees to the Purchaser or the Purchaser's
     Group and the Purchaser shall not be liable for any salary, benefits,
     retirement or severance benefits relating to these Excluded Employees. The
     Vendor shall indemnify each member of the Purchaser's Group against any
     liabilities, costs, damages, claims, expenses arising or incurred by any
     member of the Purchaser's Group regarding the Excluded Employees.

VENDOR'S INDEMNITY

(M)  The Vendor shall perform and discharge all of its obligations in respect of
     all Employees and Seconded Employees in respect of the period prior to the
     Completion Date and shall indemnify each member of the Purchaser's Group
     against any liabilities, costs, damages, claims or reasonable expenses
     arising or incurred by any member of the Purchaser's Group arising out of
     or relating to any act or omission by any member of the Vendor's Group or
     any Company in respect of the period prior to the Completion Date in
     respect of any of its obligations or duties to or in relation to the
     employment of any of the Employees or any former employees of any members
     of the Vendor's Group or any Company in respect of the period prior to
     Completion; PROVIDED that this SUB-CLAUSE (M) shall not apply in relation
     to any liabilities in respect of the provision of Group Plan Benefits or in
     relation to any liabilities disclosed in the Disclosure Letter or taken
     into account in the Completion Accounts or, for the avoidance of doubt,
     with respect to any liability or obligation in respect of bodily injury to
     any Employee in respect of which the provisions of SUB-CLAUSES 10(C)(vi),
     15(I), 15(J) and 15(K) shall apply. Such liabilities shall include those
     incurred as a result of the termination of employment of an Employee where
     notice has been given to the Employee by a member of the Vendor's Group or
     a Company prior to Completion but where such notice has not expired by
     Completion provided that, in such a case, shall exclude any liabilities
     arising in respect of the period on and after Completion due to the acts or
     omissions of a member of the Purchaser's Group.

(N)  The Purchaser shall and shall procure that each relevant member of the
     Purchaser's Group shall:

     (i)    as soon as practicable after becoming aware of such a matter, notify
            the Vendor of any matter which may be likely give rise to a claim
            for indemnification under SUB-CLAUSE (M);




                                       29

     (ii)   give the Vendor or the relevant member of the Vendor's Group all
            reasonable co-operation, assistance and information which may be
            reasonably requested to dispute, resist, appeal, defend, remedy or
            mitigate the matter;

     (iii)  not admit, defend, compromise, negotiate or settle any claim arising
            out of such matter without the consent of the Vendor or the relevant
            member of the Vendor's Group in writing, such consent not to be
            unreasonably withheld or delayed; and

     (iv)   allow the Vendor or the relevant member of the Vendor's Group to
            have conduct of any litigation and negotiations in connection with
            any claim arising out of such matter if so requested by the Vendor,

     provided that there should be no rights under this SUB-CLAUSE (N) unless
     the Vendor agrees to indemnify the Purchaser against any reasonable costs,
     liabilities, damages, claims or expenses in respect of SUB-CLAUSES (N)(ii),
     (iii) AND (iv) above. The Purchaser undertakes that it will not, and will
     procure that no member of the Purchaser's Group will, suggest, promote,
     support or assist any claim which may give rise to a claim for
     indemnification under SUB-CLAUSE (M).

FRENCH EMPLOYEES

(O)  The Vendor and the Purchaser anticipate that, in relation to the French
     Employees, the Transfer Regulations will apply to the sale and purchase of
     the Transferring Business under this Agreement so that the contracts of
     employment of the French Employees will have effect after Completion as if
     originally made between the relevant Designated Purchaser and the French
     Employees.

(P)  If the contract of employment of any person who is not a French Employee is
     found or alleged to have effect after Completion as if originally made with
     the Purchaser or another member of the Purchaser's Group as a consequence
     of the application of the Transfer Regulations to the sale and purchase of
     the Transferring Business under this Agreement, the Vendor agrees that:

     (i)    in consultation with, and if so requested by, the Purchaser, it
            will, within seven Business Days after being so requested by the
            Purchaser (as long as the request is made no later than fourteen
            Business Days after the Purchaser becomes aware of such finding or
            allegation), make to that person an offer in writing to employ him
            under a new contract of employment to take effect upon the
            termination referred to below; and

     (ii)   the offer to be made will be such that none of the terms and
            conditions of the new contract will differ from the corresponding
            provision of that person's contract of employment immediately before
            Completion.

     Upon that offer being made (or at any time after the expiry of the seven
     Business Days if the offer is not made as requested), the Purchaser shall
     terminate, or shall procure the termination of the employment of the person
     concerned.


                                       30

(Q)  If the contract of employment of any French Employee is found or alleged
     not to have effect after Completion as if originally made with the relevant
     Designated Purchaser as a consequence of the application of the Transfer
     Regulations to the sale and purchase of the Transferring Business under
     this Agreement, the Purchaser agrees that:

     (i)    in consultation with the Vendor, it will, within seven days of being
            so requested by the Vendor (as long as the request is made no later
            than fourteen Business Days after the Vendor becomes aware of such
            finding or allegation), procure that the relevant Designated
            Purchaser makes to the relevant Employee an offer in writing to
            employ him under a new contract of employment to take effect upon
            the termination referred to below; and

     (ii)   the offer to be made will be such that none of the terms and
            conditions of the new contract (other than the identity of the
            employer) will differ from the corresponding provisions of the
            Employee's contract of employment immediately before Completion.

     Upon that offer being made (or after the expiry of the seven Business Days
     if the offer is not made as requested), the Vendor shall forthwith
     terminate, or procure the termination of, the employment of the Employee
     concerned. The Vendor undertakes that before any termination of employment
     of this nature it will not make any change, and will procure that no change
     is made, to the terms and conditions of the relevant Employee's contract of
     employment as existing immediately before Completion.

(R)  The Purchaser (on behalf of the relevant Designated Purchaser) shall
     indemnify each member of the Vendor's Group against any liability
     whatsoever in respect of the French Employees arising out of or relating to
     any act or omission by any member of the Purchaser's Group either before or
     after Completion including, without limitation, any breach of the relevant
     Designated Purchaser's obligations or duties under the Transfer Regulations
     and any breach of the Purchaser's obligations under SUB-CLAUSES 13(P) and
     13(Q). This indemnity shall not extend to acts or omissions of the
     Companies prior to Completion.

US EMPLOYEES

(S)  The following provisions of this CLAUSE 13 are without prejudice to the
     preceding provisions of this CLAUSE 13.

(T)  Immediately upon Completion the Vendor shall procure that the US Business
     Seller terminates the employment of all the US Employees and the relevant
     Designated Purchaser shall hire all the US Employees, on terms and
     conditions complying with the Purchaser's obligations under the preceding
     provisions of this CLAUSE 13 (including, for the avoidance of doubt each US
     Employee's entitlements to payments in respect of the Long Term Incentive
     Plan and Short Term Incentive Plan), and the Purchaser (on behalf of the
     relevant Designated Purchaser) shall indemnify each member of the Vendor's
     Group against all costs, liabilities, damages and expenses incurred by each
     member of the Vendor's Group (including, for the avoidance of doubt, the
     termination benefits referred to in the succeeding sentence) as a result of
     any breach by the Purchaser or



                                       31

     relevant Designated Purchaser of this SUB-CLAUSE (T). If the relevant
     Designated Purchaser fails so to hire any US Employee, the termination
     benefits set out in ATTACHMENT 12 shall be applied by the Vendor except
     where the failure so to hire such US Employee was due to such US Employee's
     refusal to accept an offer of employment from the relevant Designated
     Purchaser for a reason other than:

     (i)    the failure of the Purchaser or the relevant Designated Purchaser to
            comply with its obligations under the preceding provisions of this
            CLAUSE 13; or

     (ii)   a reason set out in points 2) or 3) of the third bullet point of
            ATTACHMENT 12.

(U)  With respect to the US Employees, the Vendor shall procure that the US
     Business Seller and any other relevant member of the Vendor's Group retain
     liability under any of their group life, accident, worker's compensation,
     medical, hospitalisation, prescription drug, dental, reimbursement account
     or short-term or long-term disability plans, whether or not insured, for
     any claims arising prior to the Completion Date except to the extent such
     liabilities are disclosed in the Disclosure Letter or are taken into
     account in the preparation of the Completion Accounts and the Purchaser (on
     behalf of the relevant Designated Purchaser) shall assume all liability for
     claims arising on or after the Completion Date under the relevant
     Designated Purchaser's group life, accident, worker's compensation,
     medical, hospitalisation, prescription drug, dental, reimbursement account
     or short-term or long-term disability plans. For the purposes of this
     SUB-CLAUSE (U), claims shall be deemed to have arisen:

     (i)    with respect to all death or dismemberment claims, on the actual
            date of death or dismemberment;

     (ii)   with respect to disability claims, on the day the claimant makes a
            claim for the relevant benefit;

     (iii)  with respect to claims under salary continuance plans, on an ongoing
            basis by reference to the period to which the payment of salary
            relates;

     (iv)   with respect to all hospital, medical, drug or dental claims, on the
            date the service or supply was purchased or received by the
            claimant; and

     (v)    with respect to worker's compensation claims which are
            single-accident specific, on the date of the occurrence, and with
            respect to all other worker's compensation claims, on the date the
            award is made; PROVIDED that neither the Vendor nor any other member
            of the Vendor's Group shall have any liability in respect of matters
            arising prior to Completion which form part of any claim brought by
            an Employee more than 3 years after Completion.

(V)  The Vendor shall procure that the US Business Seller and any other relevant
     member of the Vendor's Group transfer as of the Completion Date the excess,
     if any, of the accumulated contributions to their health and dependent care
     flexible spending account plans made by the US Employees over the pay-outs
     made from such accounts to such employees as of the Completion Date, to
     corresponding accounts set up in the relevant






                                       32

     Designated Purchaser's flexible spending account plans. The Purchaser (on
     behalf of the relevant Designated Purchaser) agrees to cause its flexible
     spending account plans to honour and continue through the end of the
     calendar year in which the Completion Date occurs the elections as in
     effect immediately prior to the Completion Date made by US Employees in
     respect of which a transfer is made. Following the transfer to the
     Purchaser's flexible spending account plans, the relevant Designated
     Purchaser shall be responsible for such transferred excess amounts in its
     flexible spending account plans and all claims (without duplication of
     claims reimbursed by the US Business Seller or any other member of the
     Vendor's Group prior to such transfer) made by US Employees for
     reimbursement under such flexible spending account plans.

(W)  On and after the Completion Date the Purchaser shall, or shall procure that
     the relevant members of the Purchaser's Group shall, give the US Employees
     full credit for all purposes (including for purposes of eligibility to
     participate, early retirement eligibility and early retirement subsidies
     and vesting) under any employee benefit plans or arrangements maintained by
     the members of the Purchaser's Group for the US Employees' service with the
     US Business Seller or any other member of the Vendor's Group to the same
     extent recognised by the US Business Seller and other relevant members of
     the Vendor's Group immediately prior to Completion.

(X)  To the extent permitted by law, the Purchaser shall, or shall procure that
     the relevant member of the Purchaser's Group shall, assume all US
     Employees' accrued compensation, bonus and vacation liabilities, regardless
     of whether such liabilities relate to events which occurred on or prior to
     Completion (except for the unfunded deferred compensation arrangements for
     which liability will be retained by the US Business Seller and any other
     relevant member of the Vendor's Group).

(Y)  As of the Completion Date, the Purchaser (or the relevant Designated
     Purchaser) shall be responsible for any legally mandated continuation of
     health care coverage under federal or state law for all US Employees and/or
     their covered dependants who have a loss of health care coverage under
     health plans applicable to any US Employee with effect from the Completion
     Date due to a qualifying event (as defined in Section 4980B of the US
     Internal Revenue Code of 1986, as amended (the "CODE")) that occurs on or
     after the Completion Date. The Vendor or relevant member of the Vendor's
     Group shall be responsible for any legally mandated continuation of health
     coverage for all US Employees and/or their covered dependants who have a
     loss of health care coverage under health plans of the Vendor's Group due
     to a qualifying event that occurs prior to the Completion Date except to
     the extent that any relevant liabilities are disclosed in the Disclosure
     Letter or taken into account in the preparation of the Completion Accounts.

(Z)  The Purchaser shall procure that for a period of three years following the
     Completion Date, each US Employee who is employed by any member of the
     Purchaser's Group or any person to whom the whole or part of the US
     Business or the Purchaser's Group is transferred shall be provided with
     coverage under a "group health plan" (within the meaning of Code Section
     4980B(g)(2)) that is substantially similar (taking into account both the
     services provided under such plan and the cost of such coverage that is
     borne by the US Employee (both as an absolute amount and in comparison to
     the cost of such coverage payable by the employer)) to the coverage under a
     group health plan







                                       33

     maintained by the Vendor's Group provided to such US Employee immediately
     prior to the Completion Date.

14. PENSIONS

    Each of the parties shall comply with the requirements relating to that
    party set out in SCHEDULE 8 (Pensions).

15. RISK AND INSURANCE

 GENERAL

(A)  Risk in the IP Assets, the US Business Assets and the Monoclonal Assets
     shall pass to the Purchaser and the other relevant Designated Purchasers on
     Completion.

(B)  The Purchaser acknowledges and agrees (on behalf of itself and each other
     member of the Purchaser's Group) that, following Completion, in respect of
     all insurance cover provided in relation to the Transferring Business
     pursuant to policies maintained by the Vendor's Group (whether such
     policies are maintained with third party insurers or with other members of
     the Vendor's Group), no claim shall be made by any of the Companies or in
     relation to the IP Assets, the US Business, the US Business Assets, the
     Bedford Property or the Monoclonal Assets other than the following which
     shall be permitted:

     (i)    any claim in respect of any losses, events, circumstances or
            occurrences notified to the relevant insurer before Completion; or

     (ii)   any claim in respect of any losses, events, circumstances or
            occurrences arising prior to Completion where such losses, events,
            circumstances or occurrences are, subject to SUB-CLAUSES (D) and
            (I), notified to the relevant insurer within 90 days of Completion,

     and SUB-CLAUSE B(i) and (ii) shall include, but not be limited to, any
     losses, events, circumstances or occurrences arising prior to Completion in
     respect of the marketing, sale or use of any Persona products sold by any
     Company or any member of the Vendor's Group (including, without limitation,
     Unipath Diagnostics S.A. (France)) before Completion. (For the purposes of
     this CLAUSE 15, Persona products will be deemed to have been sold when
     title in the Persona product passed from the relevant Company or member of
     the Vendor's Group to a third party).

(C)  Subject to SUB-CLAUSES 15(B), (E), (F) and (J) and SUB-CLAUSE 13(J)(iii),
     the Purchaser acknowledges and agrees (on behalf of itself and each other
     member of the Purchaser's Group) that, upon Completion, the insurance cover
     provided in relation to the Transferring Business pursuant to policies
     maintained by members of the Vendor's Group shall cease.



                                       34

 PERSONA LITIGATION

(D)      The 90 day time limit (set out in SUB-CLAUSE (B)(II)) for notification
         of losses, events, circumstances or occurrences arising prior to
         Completion shall not apply in relation to losses, events, circumstances
         or occurrences arising in respect of the marketing, sale or use of any
         Persona products sold by any Company or any member of the Vendor's
         Group (including, without limitation, Unipath Diagnostics S.A.
         (France)) before Completion.

(E)      The Vendor undertakes that from Completion the Companies shall (at no
         cost to themselves) be Insureds under, subject to and as defined in the
         Liability Insurance Policies for the purposes of the entitlement in
         CLAUSE 15(B) to make notifications and claims under those Liability
         Insurance Policies in respect of any occurrence (for the purposes of
         the entitlement in CLAUSE 15(B)) which arose prior to Completion. Any
         such notification and claim shall be subject to the terms, conditions
         and limits of those Liability Insurance Policies.

(F)      If, in respect of any matter which would give rise to a claim under
         CLAUSE 10(A) arising from Assumed Liabilities falling within SUB-CLAUSE
         10(B)(III), any member of the Vendor's Group (including, without
         limitation, Unipath Diagnostics S.A. (France)) is entitled to claim
         under any Liability Insurance Policy, then no such matter shall be the
         subject of a claim under CLAUSE 10(A) unless and until the appropriate
         member of the Vendor's Group (including, without limitation, Unipath
         Diagnostics S.A. (France)) shall have made a claim against its insurers
         and used all reasonable endeavours to pursue such insurance claim
         including where reasonable and appropriate commencing and prosecuting
         proceedings against insurers (and for the purposes of dealing with
         insurers in respect of such insurance claims the appropriate member of
         the Vendor's Group (including, without limitation, Unipath Diagnostics
         S.A. (France)) shall act in accordance with the reasonable guidance and
         direction of the Purchaser). There shall, moreover, be no liability
         under CLAUSE 10(A) in respect of Assumed Liabilities falling within
         SUB-CLAUSE 10(B)(III) to the extent of the amount recovered under such
         insurance claim except to the extent:

         (i)      of the reasonable costs and expenses and any Taxation incurred
                  or suffered by any member of the Vendor's Group in connection
                  with the recovery; and/or

         (ii)     that the future insurance costs of the Vendor or any other
                  member of the Vendor's Group are increased by the matter
                  giving rise to the insurance claim or the claim itself.

(G)      The Vendor warrants (for itself and on behalf of the Share Sellers) to
         the Purchaser (for itself and on behalf of the other Designated
         Purchasers and the Companies) as at the date hereof that:

         (i)      the facts set out in a letter from the Captive Insurer to
                  Richard Hazell of Unilever PLC dated 18th December, 2001,
                  included at tab 15 of the Disclosure Bundle, are true and
                  accurate in all material respects and are not misleading in
                  any material respect;

         (ii)     the aggregate limit of indemnity of all group liability
                  insurance cover provided in relation to the Transferring
                  Business pursuant to the Liability Insurance Policies

                  limitation, Unipath Diagnostics S.A. (France)) in respect of

                  Diagnostics S.A. (France)) has (by act or omission) done
                  anything which would render any Liability Insurance Policy
                  void or voidable, or entitle any relevant insurer to repudiate
                  or rescind any such Liability Insurance Policy, in respect of
                  any claim made or notifiable under it relating to any matters,
                  losses, events, circumstances or occurrences arising prior to
                  Completion in respect of the marketing, sale or use of Persona
                  products sold by any Company or any member of the Vendor's
                  Group (including, without limitation, Unipath Diagnostics S.A.
                  (France)) before Completion; and

         (vii)    any claim or circumstance known to any Company or any member
                  of the Vendor's Group (including, without limitation, Unipath
                  Diagnostics S.A. (France)) relating to the Transferring
                  Business arising out of the marketing, sales or use of Persona
                  products sold before Completion which is notifiable to any
                  insurer under any Liability Insurance Policy has been notified
                  to such insurer in accordance with the conditions set out in
                  the relevant Liability Insurance Policy.

(H)      The Vendor undertakes to the Purchaser (for itself and on behalf of
         each other member of the Purchaser's Group) that:

         (i)      it shall not (and shall procure that each member of the
                  Vendor's Group (including, without limitation, Unipath
                  Diagnostics S.A. (France)) shall not) take or omit to take any
                  action which shall have the effect of making any Liability
                  Insurance Policy void or voidable, or entitle any relevant
                  insurer to repudiate or rescind any such Liability Insurance
                  Policy, in respect of any claim made or notifiable before
                  Completion under it relating to any losses, events,
                  circumstances or occurrences arising prior to Completion in
                  respect of the marketing, sale or use of Persona products sold
                  by any Company or any member of the Vendor's Group (including,
                  without limitation, Unipath Diagnostics S.A. (France)) before
                  Completion;

         (ii)     it shall procure that after the date of this Agreement the
                  Captive Insurer shall exercise its rights in relation to the
                  conduct of any Persona Litigation under any Liability
                  Insurance Policy in a manner substantially consistent with its
                  usual practices in relation to claims under those Liability
                  Insurance Policies prior to the date hereof; provided that if
                  so requested by the Purchaser, the Vendor and each other
                  relevant member of the Vendor's Group (including, without
                  limitation, Unipath Diagnostics S.A. (France)) shall use their
                  reasonable endeavours to procure that the leading
                  insurer on the first commercial market insurance layer
                  affected shall give guidance and directions to the Captive
                  Insurer as to the exercise of those rights, and the Vendor
                  shall procure that the Captive Insurer shall, if the Purchaser
                  so requests, act in accordance with such guidelines and
                  instructions;

         (iii)    it will procure that the Captive Insurer treats as a single
                  occurrence under the Liability Insurance Policy for the
                  1996/97 policy year all claims notified or threatened before
                  the date hereof in respect of the marketing, sale or use of
                  Persona products sold before Completion and any future claim
                  containing substantially similar allegations to those already
                  notified as Generic Claims; provided that the Captive Insurer
                  shall be entitled to treat occurrences after 30th April, 2001
                  but before Completion as falling within the Liability
                  Insurance Policy for the 2001/02 policy year; and provided
                  further that it is acknowledged by the parties that the claim
                  of Mrs. Wooster and any claim of a like nature or which is
                  alleged to arise from a separate and distinct defect in any
                  Persona product, or in the manner in which it was marketed,
                  sold or used, may not form part of the Generic Claims and may
                  be treated by the Captive Insurer otherwise than as part of
                  the single occurrence under the Liability Insurance Policy for
                  the 1996/7 policy year; and

         (iv)     it will indemnify the Companies for any loss suffered by any
                  of them by reason of the failure of the Captive Insurer, as a
                  result of its insolvency, to satisfy on a reasonably timely
                  basis any liability of the Captive Insurer to any of the
                  Companies under the Liability Insurance Policies underwritten
                  by the Captive Insurer in favour of the Companies in respect
                  of any claim arising from the marketing, sale or use of
                  Persona products sold before Completion notified by or on
                  behalf of any of them to it on or prior to the date hereof or
                  pursuant to CLAUSE 15.




                                       35

EMPLOYERS' LIABILITY

(I)  The 90 day time limit (set out in SUB-CLAUSE (B)(ii)) for notification of
     losses, events, circumstances or occurrences arising prior to Completion
     shall not apply in relation to losses, events, circumstances or occurrences
     arising in respect of any claim by an Employee or any past employee (or
     their executors, personal representatives or dependants) of any of the
     relevant Companies as set out in (i) or (ii) as appropriate below arising
     out of and in the course of his employment by any such Company prior to
     Completion:

     (i)    against any Company incorporated in England and Wales if that
            Company is insured in respect of those claims under any policy of
            employers' liability insurance maintained by any relevant member of
            the Vendor's Group on or before Completion; and

     (ii)   against each of the Companies if that Company is insured in respect
            of those claims under the extension in the Liability Indemnity
            Policies referred to in the Liability Insurance Policies as
            "Residual Employers Liability Insurance".

(J)  The Vendor undertakes that from Completion any Company incorporated in
     England and Wales shall (at no cost to themselves) be Insureds under,
     subject to and as defined in any policy of employers' liability insurance
     maintained by any relevant member of the Vendor's Group on or before the
     date of Completion for the purposes of the entitlement in CLAUSE 15(B) to
     make notifications and claims to which SUB-CLAUSE (I)(i) refers. Any such
     notification and claim shall be subject to the terms, conditions and limits
     of the relevant policy of employers' liability insurance. For the avoidance
     of doubt, pursuant to SUB-CLAUSE (E) each of the Companies shall (at no
     cost to themselves) be Insureds under, subject to and as defined in the
     Liability Insurance Policies in respect of the "Residual Employers'
     Liability Insurance" coverage provided under those Liability Insurance
     Policies in respect of any occurrence in respect of any claim by an
     Employee or any past employee (or their executors, personal representatives
     or dependants) of any of the relevant Companies which arose out of and in
     the course of his employment by any such Company prior to Completion.

(K)  The Vendor acknowledges that neither the Vendor nor any other member of the
     Vendor's Group (including, if applicable and without limitation, Unipath
     Diagnostics S.A. (France)) shall take any voluntary action (excluding any
     action taken to effect completion of the transactions contemplated by this
     Agreement) to terminate any employers' liability insurance arrangements
     effected prior to Completion by those Companies incorporated in France,
     Germany, the Netherlands and Sweden which are not policies maintained by
     the Vendor's Group.

(L)  (i)    In calculating the liability of the Vendor for any breach of the
            undertakings set out in SUB-CLAUSES (E) and/or (J) or any of the
            warranties set out in SUB-CLAUSE (G) there shall be taken into
            account any repayment in respect of Tax or



                                       36

            any Relief arising as a result of the matter giving rise to such
            liability which the Purchaser or any member of the Purchaser's
            Group obtains and utilises on or before the date of calculating
            such liability.

     (ii)   To the extent that the Purchaser (or the relevant member of the
            Purchaser's Group) obtains and utilises any repayment in respect of
            Tax or any Relief arising as a result of the matter giving rise to
            the liability of the Vendor for any breach of the undertakings set
            out in SUB-CLAUSES (E) and/or (J) or any of the warranties set out
            in SUB-CLAUSE (G), the Purchaser (or the relevant member of the
            Purchaser's Group) shall, except to the extent that such utilisation
            has been taken into account in calculating the liability of the
            Vendor pursuant to PARAGRAPH (i) of this SUB-CLAUSE (L), remit to
            the Vendor, within 15 Business Days of actual receipt, an amount
            equal to so much of the economic benefit from that repayment in
            respect of Tax or Relief which the Purchaser (or the relevant member
            of the Purchaser's Group) has actually received; PROVIDED that
            nothing in this PARAGRAPH (ii) shall restrict the ability or
            discretion of the Purchaser (or the relevant member of the
            Purchaser's Group) to order its Tax affairs in any way which it sees
            fit and to keep its Tax affairs confidential. Any question
            concerning whether the Purchaser (or the relevant member of the
            Purchaser's Group) has actually realised any such economic benefit
            or the quantum and timing of such benefit shall be determined by the
            auditors for the time being of the Purchaser (or the relevant member
            of the Purchaser's Group).

(M)  Without prejudice to the provisions of SUB-CLAUSE 15(L), any payment made
     by a member of the Vendor's Group or any other person in respect of any
     breach of the undertakings set out in SUB-CLAUSES (E) and/or (J) or any of
     the warranties set out in SUB-CLAUSE (G) shall be deemed, so far as
     possible, to be a reduction of the Cash Consideration payable by the
     Purchaser (on behalf of the relevant Designated Purchaser) and such
     reduction shall be allocated to the greatest extent possible to the
     particular Shares or US Business Assets to which the claim relates. Any
     such payment, to the extent not deemed to be such a reduction of the Cash
     Consideration, shall be made on an after Tax basis.

16. DUTCH SALES STAFF

(A)  The Vendor shall procure that, as soon as reasonably practicable following
     Completion, consultation shall commence with the Dutch Sales Staff in the
     manner prescribed by the law of the Netherlands with a view to securing
     their consent to enter into new contracts of employment, as soon as
     reasonably practicable after Completion, with the relevant Designated
     Purchaser or such Company as the Purchaser may nominate. The Vendor shall
     use its reasonable endeavours to finalise the consultation process with the
     Dutch Sales Staff in an efficient and timely manner.

(B)  The Vendor and the Purchaser agree to do all that they are each reasonably
     capable of doing to enable compliance with the relevant obligations of the
     law of the Netherlands (including, without limitation, the prompt provision
     to the Vendor of all information reasonably necessary to satisfy the
     obligations of the Vendor or any other member of




                                       37

     the Vendor's Group to consult with the Dutch Sales Staff in accordance with
     local law) with respect to the Dutch Sales Staff and to enter into new
     contracts of employment.

(C)  If all or any member of the Dutch Sales Staff does not agree to enter into
     new contracts of employment with the relevant Designated Purchaser or such
     company as the Purchaser may nominate within six months of Completion, the
     Vendor and the Purchaser shall procure that the Dutch Sales Representation
     Agreement is terminated with respect to the Dutch Sales Staff, unless the
     termination of the Dutch Sales Representation Agreement less than 6 months
     after Completion would prejudice the on-going consultation process with the
     remaining Dutch Sales Staff, in which case the parties agree to delay such
     termination (or to terminate in respect of the non-transferring Dutch Sales
     Staff only) until up to a maximum of 6 months from Completion. The Vendor
     (on behalf of Lever Faberge Nederland B.V.) and the Purchaser (on behalf of
     Unipath Limited) agree that if the Dutch Sales Representation Agreement is
     terminated pursuant to this SUB-CLAUSE (C) then paragraph 10 of that
     agreement shall not apply and the Vendor shall procure that Lever Faberge
     Nederland B.V. shall bear the costs referred to therein. If some of the
     Dutch Sales Staff do not agree to enter into new contracts of employment
     with the relevant Designated Purchaser or such company as the Purchaser may
     nominate within six months of Completion, the Vendor shall procure that
     Lever Faberge Nederland B.V. shall bear the costs related to such
     non-transferring Dutch Sales Staff.

(D)  In the event that any or all of the members of the Dutch Sales Staff do
     enter into an employment contract with the relevant Designated Purchaser or
     such company as the Purchaser may nominate within six months of Completion,
     the Purchaser will observe the obligations set out in SUB-CLAUSES 13(B) to
     13(I) (Employees) and Part B of SCHEDULE 8 (Pensions) as if they applied to
     such member of the Dutch Sales Staff. Following any such transfer of the
     employment of such member of the Dutch Sales Staff, the Vendor and the
     Purchaser shall procure that the Dutch Sales Representation Agreement is
     terminated with respect to such member of the Dutch Sales Staff. The Vendor
     (on behalf of Lever Faberge Nederland B.V.) and the Purchaser (on behalf of
     Unipath Limited) agree that if the Dutch Sales Representation Agreement is
     terminated pursuant to this SUB-CLAUSE (D) then paragraph 10 of that
     agreement shall not apply and each of Lever Faberge Nederland B.V. and
     Unipath Limited shall bear its own costs (if any) in relation to such
     termination.

(E)  The Vendor shall procure that neither Lever Faberge Nederland B.V. nor any
     other member of the Vendor's Group shall terminate the Dutch Sales
     Representation Agreement otherwise than pursuant to SUB-CLAUSE (C) or (D).
     The Purchaser (on behalf of Unipath Limited) agrees with the Vendor (on
     behalf of Lever Faberge Nederland B.V.) that, pending termination of the
     Dutch Sales Representation Agreement, Lever Faberge Nederland B.V. will
     have no obligation to replace any member of the Dutch Sales Staff who
     leaves the employment of Lever Faberge Nederland B.V. and that such a
     departure shall not constitute a breach of the Dutch Sales Representation
     Agreement.

(F)  The Vendor (on behalf of Lever Faberge Nederland B.V.) and the Purchaser
     (on behalf of Unipath Limited) agree that if the Dutch Sales Representation
     Agreement is


                                       38

     terminated other than pursuant to SUB-CLAUSE (C) or (D) then paragraph 10
     of that agreement shall apply.

(G)  For the avoidance of doubt, the Dutch Sales Staff shall continue to be
     employed by Lever Faberge Nederland B.V. following Completion and this
     Agreement shall not operate to transfer their employment to the Purchaser
     or any other member of the Purchaser's Group until such time as they agree
     to enter into an employment contract with a member of the Purchaser's
     Group.

17. INTELLECTUAL PROPERTY

"WRONG POCKETS"

(A)  If either party discovers that any of the Business IPR or Company IPR has
     been used exclusively by a member of the Vendor's Group in the twelve
     months prior to Completion other than in connection with the Transferring
     Business, or has never been used prior to Completion in connection with the
     Transferring Business (and for these purposes use includes use for
     research, development or commercially or any of them), the Purchaser agrees
     to procure, at the Vendor's cost, that such Intellectual Property is
     transferred to the Vendor or a company nominated by the Vendor for nominal
     consideration as soon as reasonably practicable.

(B)  If either party discovers that any member of the Vendor's Group owns any
     Intellectual Property or know-how which has been used exclusively in the
     Transferring Business in the twelve months prior to Completion, or has
     never been used by a member of the Vendor's Group prior to Completion other
     than in connection with the Transferring Business (and for these purposes
     use includes use for research, development, commercially or any of them),
     the Vendor agrees to procure that such Intellectual Property or know-how
     (as applicable) is transferred to the Purchaser or a company nominated by
     the Purchaser for nominal consideration as soon as reasonably practicable.

SHARED RIGHTS

(C)  Each party shall have the rights and obligations relating to that party as
     set out in SCHEDULE 16 (INTELLECTUAL PROPERTY LICENCES).

BD LICENCE

(D)  The Purchaser acknowledges that following Completion it or a member of the
     Purchaser's Group may receive sums from Becton Dickinson pursuant to the BD
     Licence. The Purchaser undertakes that:

     (i)    it will pay to the Vendor all sums received by the Purchaser or
            members of the Purchaser's Group pursuant to CLAUSE 3.1 of the BD
            Licence; PROVIDED that any sum payable by the Purchaser pursuant to
            this SUB-CLAUSE 17(D)(i) shall be reduced by an amount corresponding
            to Taxation payable by the Purchaser (or the relevant member of the
            Purchaser's Group) in respect of such sum



                                       39


            received, except to the extent that the corresponding sum payable
            by the Purchaser is tax deductible for the Purchaser (or relevant
            member of the Purchaser's Group) for the purposes of calculating
            income, profits or gains;

     (ii)   neither it nor any member of the Purchaser's Group will within five
            years from the date of this Agreement:

            (a) directly or indirectly grant a licence to Becton Dickinson or
                any related company to use the Biosensors Patents; or

            (b) enter into any other agreement with Becton Dickinson or any
                other company pursuant to which Becton Dickinson acquires the
                right to use the Biosensors Patents,

            in relation to electrochemical biosensors for markers for diabetes,
            including the analysis of glucose in blood, on whatever terms and
            whether for monetary consideration or otherwise; and

     (iii)  it will observe all the rights of Becton Dickinson under the BD
            Licence.

TREATMENT OF PATENT CASES

(E)  The provisions of Part B of SCHEDULE 15 (Patent Cases) shall apply in
     relation to the treatment of the Patent Cases by the parties following
     Completion.

AUDIT RIGHTS

(F)  Each of the Vendor and the Purchaser shall give the other party such access
     to those books, records and employees of the members of the Vendor's Group
     or the Purchaser's Group (as the case may be) which the other party may
     reasonably require to ascertain that the members of the Vendor's Group or
     the Purchaser's Group (as the case may be) are in compliance with their
     obligations under this CLAUSE 17 and/or Part B of SCHEDULE 15 (Patent
     Cases). Such employees to whom the requesting party may require access
     shall be instructed to give promptly all such information and explanations
     as the requesting party may reasonably require for this purpose, and each
     party shall be entitled to take photocopies of relevant documentation.

PAYMENTS

(G)  Any payments made by the Purchaser pursuant to SUB-CLAUSE (D) shall be
     received by the Vendor on behalf of the relevant IP Assets Sellers.

18. REORGANISATION INDEMNITY

(A)  Subject to the remaining provisions of this CLAUSE 18, the Vendor agrees
     with the Purchaser that it will indemnify each member of the Purchaser's
     Group in respect of all liabilities, losses, charges, costs, claims or
     demands ("INDEMNIFIED LOSSES") to the extent that such Indemnified Losses
     are incurred by any member of the Purchaser's



                                       40

     Group as a consequence of, or which would not have occurred or arisen
     either directly or indirectly but for, the implementation of the
     Reorganisation. Any payments made by the Vendor pursuant to this SUB-CLAUSE
     (A) shall be by way of adjustment to the Cash Consideration paid in respect
     of the Shares of Unipath Limited.

(B)  The indemnity set out in SUB-CLAUSE (A) does not apply to any Indemnified
     Losses relating to Tax or UK stamp duty and the only remedy in respect of
     such Indemnified Losses shall be pursuant to the Tax Covenant.

(C)  Where the Purchaser or any member of the Purchaser's Group becomes aware of
     any liability of the Subsidiary or Unipath Limited arising as a result of
     the failure to obtain the consent of a third party creditor (in
     circumstances where such consent was required under contract or law and was
     not obtained), or of any matter likely to give rise to such a liability, in
     each case which gives or is likely to give rise to Indemnified Losses
     arising out of the sale by the Subsidiary to Unipath Limited of
     substantially all of the business and assets of the Subsidiary (in
     accordance with Step 2 of the Reorganisation (as described IN ATTACHMENT 2)
     (the "STEP TWO HIVE-DOWN")) the Purchaser shall notify the Vendor of such
     liability, or such matter, as soon as reasonably practicable after becoming
     aware thereof and the Purchaser shall, and shall procure that each other
     member of the Purchaser's Group shall (i) co-operate with the Vendor with
     regard to such liability or matter to the extent reasonable; and (ii) take
     all reasonable steps to mitigate any Indemnified Losses arising from such
     liability or matter, PROVIDED that, for the purposes of this SUB-CLAUSE
     (ii), it shall not be considered reasonable for any member of the
     Purchaser's Group to take any step to the extent that it would prejudice
     the operations of the Transferring Business.

(D)  The Purchaser undertakes to the Vendor (for itself and as trustee for each
     member of the Vendor's Group and for all the past, present and future
     employees and directors of each member of the Vendor's Group and of the
     Subsidiary (together, "PROTECTED PERSONS")) that it will not, and will
     procure that no member of the Purchaser's Group (subject to SUB-CLAUSE
     18(F), while it remains such a member) will, except in the case of fraud,
     make any claim or bring any proceedings (whether pursuant to the indemnity
     set out in SUB-CLAUSE (A) or otherwise) alleging that the sale by the
     Subsidiary to the Vendor of the entire issued share capital of Unipath
     Limited (in accordance with step three of the Reorganisation (as described
     in ATTACHMENT 2) (the "STEP THREE SALE")) involved an unlawful distribution
     or an unlawful reduction of capital effected by the Subsidiary. The
     undertaking by the Purchaser set out in this SUB-CLAUSE (D) shall not apply
     where any Tax Authority makes a claim or brings proceedings against a
     member of the Purchaser's Group alleging that the Step Three Sale involved
     an unlawful distribution or an unlawful reduction of capital effected by
     the Subsidiary or if the Vendor or any member of the Vendor's Group makes a
     legal challenge (other than by reason of the failure of the Purchaser or
     any Designated Purchaser to have legal capacity to enter into this
     Agreement and/or to purchase such Shares hereunder) to the rights of the
     Purchaser or the relevant Designated Purchaser as purchaser of the Shares
     in Unipath Limited in accordance with the provisions of SUB-CLAUSES 2(A) -
     (C). Where the undertaking by the Purchaser in this SUB-CLAUSE (D) applies
     and is breached, or is alleged by the Purchaser or any member of the
     Purchaser's Group to be invalid, the indemnity set out in SUB-CLAUSE (A)
     shall not apply in respect of any unlawful distribution

     such unlawful distribution or unlawful reduction of capital. The
     penultimate sentence of this SUB-CLAUSE (D) is without prejudice to the
     second sentence of this SUB-CLAUSE (D).

(E)  If, as a result of breach or invalidity of the undertaking of the Purchaser
     set out in SUB-CLAUSE (D), any Protected Person becomes liable to pay any
     sum to a member of the Purchaser's Group (whether by agreement or
     otherwise) as a result of a determination or allegation (howsoever arising)
     that the Step Three Sale involved an unlawful distribution or an unlawful
     reduction of capital effected by the Subsidiary the Purchaser shall, within
     five Business Days of it being notified of such liability, pay to the
     Vendor an amount equal to such sum. This SUB-CLAUSE (E) is without
     prejudice to the second sentence of SUB-CLAUSE (D)

(F)  The Purchaser shall procure that any person not being a member of the
     Purchaser's Group (an "ACQUIRING PERSON") who, following Completion,
     acquires (directly or indirectly) all or part of the issued share capital
     of the Subsidiary from a member of the Purchaser's Group shall enter into
     undertakings in favour of the Vendor in terms which are equivalent to those
     set out in SUB-CLAUSES (D) and (E). Any undertakings with the Vendor
     entered into by an Acquiring Person pursuant to this SUB-CLAUSE (F) shall
     also impose an obligation on that Acquiring Person in equivalent terms to
     that imposed on the Purchaser by this SUB-CLAUSE (F).

     (ii)   acquiring the whole or any part of a business that includes
            activities the carrying on of which would otherwise amount to a
            breach of the undertaking contained in SUB-CLAUSE (A)(i) if the

            cent. of the aggregate turnover of the business concerned; PROVIDED
            THAT in such case the Vendor shall, or shall cause the relevant

            of the Vendor's Group, on the basis that the Vendor or such other
            member of the Vendor's Group shall allow the Purchaser a period of
            15 Business Days prior to the despatch thereof to third parties to

            referred to in paragraph (i) of the definition of Diagnostics
            Business set out in SCHEDULE 1 (Interpretation)); or

     (v)    for the avoidance of doubt, carrying on research and development
            which is primarily directed at the manufacture, development,
            marketing and/or sale of any products other than IN VITRO diagnostic
            products; or

     (vi)   holding any securities or having any other ownership or partnership
            interest in any person (for the avoidance of doubt, not being a
            member of the Vendor's Group) the purpose of which is to make and
            hold investments in different start-up or other businesses; PROVIDED
            that:

            (a) no member of the Vendor's Group is able to control or direct
                such person in any way with respect to the choice or the making
                of such investments;

            (b) no member of the Vendor's Group influences any such person to
                make or hold investments in any Restricted Business; and

                the raising of capital for any such person to invest shall not
                be restricted but shall not expressly focus on any business area
                which comprises all or any material part of the Restricted
                Business.

(C)  The Vendor (for itself and on behalf of each other member of the Vendor's
     Group) acknowledges that each restraint and undertaking contained in this
     CLAUSE 22 is both fair and reasonable and the Vendor and Purchaser express
     their intention that the





                                       55


     restraints imposed by this CLAUSE 22 be enforceable to the maximum extent
     permitted by law.

(D)  Each of the covenants, obligations and restrictions set out in this CLAUSE
     22 will be severable and independent such that if this CLAUSE 22 or any
     part or provision of this CLAUSE 22 is held or found to be wholly or partly
     void, invalid, or otherwise unenforceable then such part or provision will
     be deemed eliminated to the extent to which it is necessary to make this
     CLAUSE 22 or that part or provision enforceable.

(E)  If a court of competent jurisdiction determines that the duration of any of
     the restrictions set out in this CLAUSE 22 is unreasonably long but that a
     shorter period would be lawful and reasonable, or that the territory is too
     wide but that a different territory would be lawful and reasonable, then
     such restrictions shall be read so as to refer to such shorter period
     and/or different territory, as the court considers valid in respect of such
     restrictions.

23. PROFIT AND LOSS EQUALISATION

(A)  The Vendor and the Purchaser shall procure that the Profit and Loss
     Equalisation Agreement between Unipath Diagnostics GmbH and Deutsche
     Unilever GmbH dated 12th August, 1992 (the "PROFIT AND LOSS EQUALISATION

     2001 and ending on 31st December, 2001. The Purchaser shall procure that

            the Purchaser shall pay, or procure the payment of, an amount equal
            to such loss to the Vendor on behalf of Deutsche Unilever GmbH
            within seven Business Days of the payment being made under
            SUB-CLAUSE (C)(i).

(D)  If the accounts prepared in accordance with SUB-CLAUSE (B) show Unipath

            the Vendor shall pay, or procure the payment of, an amount equal to
            that profit to such member of the Purchaser's Group as the Purchaser
            shall nominate within 7 Business Days of the payment being made
            under SUB-CLAUSE (D)(i).

(E)  (i)    All payments to be made pursuant to this CLAUSE 23 shall be made

     (ii)   If any payment to be made pursuant to this CLAUSE 23 is not made
            within the time specified for such payment then there shall be added
            to that payment interest at the Agreed Rate.

(F)  The Purchaser shall procure that Unipath Diagnostics GmbH does not declare,
     make or pay any dividend (including, without limitation, any dividends

     a Departure-from-Group Condition by reference to the Vendor's Group.

(B)  The Purchaser shall be able, upon giving prior written notice to the
     Vendor, to assign all, but not part of, the benefit (but not the burden) of

     providing debt finance to the Purchaser's Group for the purposes of
     completing the transactions contemplated by this Agreement (the

            other person except (i) by way of re-assignment to the Purchaser; or
            (ii) following enforcement of security by The Royal Bank of Scotland
            PLC to any other person where it has received the prior written
            consent of the Vendor (such consent not to be unreasonably withheld
            or delayed);



                                       59


     (ii)   on the debt finance referred to above being repaid in full, the
            Purchaser and The Royal Bank of Scotland PLC shall procure that the
            security is released and that the benefit of this Agreement is
            re-assigned to the Purchaser; and

     (iii)  the liabilities of the Vendor and all other members of the Vendor's
            Group under this Agreement shall be no greater than such liabilities
            would have been had the assignment (or any subsequent assignment or
            re-assignment) not occurred.

(C)  The parties hereby agree that:

     (i)    where the Purchaser or a Purchaser Permitted Assignee assigns the
            benefit of this Agreement in whole or in part to any other person
            the liabilities of the Vendor and all other members of the Vendor's
            Group under this Agreement to the Purchaser's Group shall be no
            greater than such liabilities would have been had the assignment not
            occurred; and

     (ii)   where the Vendor or a Vendor Permitted Assignee assigns the benefit
            of this Agreement in whole or in part to any other person the
            liabilities of the Purchaser and all other members of the
            Purchaser's Group under this Agreement to the Vendor's Group shall
            be no greater than such liabilities would have been had the
            assignment not occurred.

     procure the doing of all such acts and/or execute or procure the execution

     Assets to the Purchaser or the relevant Designated Purchaser on the terms
     of this Agreement and the Specified Agreements and otherwise to give any
     party the full benefit of this Agreement.

(B)  The Vendor undertakes, for a period of two years after Completion and at
     the request of the relevant Designated Purchaser (and at its own cost and
     expense), and thereafter as reasonably requested by the Purchaser (at the
     Purchaser's cost and expense), to execute or procure the execution of all
     such documents as may reasonably be necessary or desirable to secure the
     vesting in the relevant Designated Purchaser of the Business IPR and the
     Domain Names provided however that the relevant Designated Purchaser
     undertakes with the Vendor that it will be responsible for preparing all
     such documents and provided that the relevant Designated Purchaser shall be
     responsible for all costs and expenses of effecting and recording the
     Intellectual Property Assignments at the relevant Patent and Trade Mark
     offices.

26.      THE ACCOUNTS AND TAX

(A)      No Company has any outstanding liability for Taxation (whether actual
         or contingent) assessable or payable by reference to profits, gains,
         income or distributions earned, received or paid or arising or deemed
         to arise:

(i)             on or at any time prior to the date of this Agreement; or

(ii)            in respect of any period starting before the date of this
                Agreement,

         that was shown to be due and payable on returns filed prior to the
         date of this Agreement.

(B)      The amount of the provision for deferred Taxation in respect of the
         Companies contained in the Accounts was, at the Accounts Date, adequate
         and in accordance with accountancy practices generally accepted in the
         country in which the relevant Company was incorporated and commonly
         adopted by companies carrying on businesses similar to the business
         carried on by that Company.

(C)      If all facts and circumstances which are now known to each Company or
         the Vendor had been known at the time the Accounts were drawn up, the
         provisions for deferred Taxation that would be contained in such
         Accounts would be no greater than the provision which is so contained.

27.      TAX EVENTS SINCE THE ACCOUNTS DATE

         Since the Accounts Date:



                                      120

                hiring or licensing of any property whether tangible or
                intangible) in circumstances where the consideration actually
                received or receivable for such disposal or supply was
                materially different to the consideration which could be deemed
                to have been received for Tax purposes;

         (iv)   no event has occurred which will give rise to a Tax liability on
                any of the Companies calculated by reference to deemed (as
                opposed to actual) income, profits or gains or which will result
                in any of the Companies becoming liable to pay or bear Tax
                liability directly or primarily chargeable against or
                attributable to another person, firm or company other than any
                of the Companies;

         (v)    no disposal has taken place or other event occurred which will
                or may have the effect of crystallising a liability to Taxation
                which should have been included in the provisions for deferred
                Taxation contained in the Accounts if such disposal or other
                event had been planned or predicted at the Accounts Date;

         (vi)   no Company has paid any interest or penalty in connection with
                any Tax, has otherwise paid any Tax after its due date for
                payment or owes any Tax the due date for payment of which has

         Business Seller and the IP Assets Sellers under the Tax Covenant and
         the Warranties (including, without limitation, any warranties implied
         by law to the extent not effectively excluded by this Agreement) shall
         not in any event exceed an amount equal to (i) (pound)77,250,000, PLUS
         or MINUS (as the case may be) (ii) 75% of any adjustment made to the
         Cash Consideration referred to in SUB-CLAUSE 3(A) pursuant to the
         provisions of SUB-CLAUSE 5(A)(i).

(C)      Each provision of this Schedule shall be read and construed without
         prejudice to each of the other provisions of this Schedule except to
         the extent specifically otherwise provided.

(D)      As regards the Tax Covenant the provisions of this Schedule shall
         operate to limit the liability of the Vendor and the Share Sellers in
         so far as any provision in this Schedule is expressed to be applicable
         thereto and the provisions of the Tax Covenant shall further operate to
         limit the liability of the Vendor and the Share Sellers in respect of
         any claim thereunder (provided that the effect of this paragraph (D)
         taken together with the Tax Covenant shall not result in the
         double-counting of any limitation).

2.       TIME LIMITS FOR BRINGING CLAIMS

         No claim shall be brought against the Vendor, the Share Sellers, the US
         Business Seller or the IP Assets Sellers in respect of any of the
         Warranties, under the Tax Covenant or in respect of PARAGRAPH 16 of
         SCHEDULE 8 unless the Purchaser shall have given to the Vendor written
         notice of such claim specifying (in reasonable detail (to the extent



                                      127

         reasonably practicable)) the matter which gives rise to the claim, the
         nature of the claim and the amount claimed in respect thereof
         (detailing (to the extent reasonably practicable) the Purchaser's
         calculation of the loss thereby alleged to have been suffered by it):-

         (i)    subject to SUB-PARAGRAPHS (ii) and (iii), on or before the
                second anniversary of the Completion Date;

         (ii)   in respect of any claims under the Tax Warranties or the Tax
                Covenant on or before the seventh anniversary of the Completion
                Date; and

         (iii)  in respect of any claims pursuant to PARAGRAPH 16 of SCHEDULE 8,
                on or before the fifth anniversary of the Completion Date,

         PROVIDED that, subject to SUB-PARAGRAPHS 5(A) and (B), the liability of
         the Vendor, the Share Sellers, the US Business Seller and the IP Assets
         Sellers in respect of such claim shall absolutely terminate (if such
         claim has not been previously satisfied, settled or withdrawn) if legal
         proceedings in respect of such claim shall not have been commenced
         within 12 months of the service of such notice and for this purpose
         proceedings shall not be deemed to have been commenced unless they
         shall have been properly issued and validly served upon the Vendor, the
         relevant Share Seller, the US Business Seller or the relevant IP Asset
         Seller (as the case may be).

3.       CONDUCT OF LITIGATION

(A)      As soon as reasonably practicable after the Purchaser or any member of
         the Purchaser's Group receives or otherwise becomes actually aware of
         any assessment, claim, action or demand by a third party (not being the
         Vendor or a member of the Vendor's Group) (a "THIRD PARTY CLAIM") which
         is reasonably likely to give rise to any claim in respect of any of the
         Warranties or pursuant to PARAGRAPH 16 of SCHEDULE 8, the Purchaser
         shall notify the Vendor in writing of such Third Party Claim. Such
         notice shall include such details of the Third Party Claim of which the
         Purchaser or any member of the Purchaser's Group is actually aware
         (including the quantum of the Third Party Claim, if known, and whether
         the Third Party Claim is (or is reasonably likely to be) an Insured
         Third Party Claim (as defined in SUB-PARAGRAPH (G) below)) and which
         the Purchaser, acting reasonably, considers relevant in order for the
         Vendor to evaluate the Third Party Claim and whether such Third Party
         Claim prima facie gives rise to a claim in respect of any of the
         Warranties or pursuant to paragraph 16 of Schedule 8.

         Any failure by the Purchaser to comply with this SUB-PARAGRAPH (A)
         shall not, for the avoidance of doubt, of itself prevent the Purchaser
         or the relevant Designated Purchaser from bringing a Warranty claim but
         none of the Vendor, the Share Sellers, the US Business Seller or the IP
         Asset Sellers shall be liable to the Purchaser or the relevant
         Designated Purchaser in respect of such Warranty claim to the extent
         that the amount of it is increased, or not reduced, as a result of such
         failure.

(B)      Subject to the provisions of PARAGRAPH (C) below, the Purchaser shall,
         and shall procure that any relevant member of the Purchaser's Group
         shall, take such action as is



                                      128

         reasonable in order to avoid, dispute, resist, mitigate or defend the
         Third Party Claim (and any related action) with reasonable diligence.
         With respect to the conduct of a Third Party Claim by the Purchaser,
         the Purchaser undertakes that:

         (i)    it shall notify the Vendor in writing of the legal counsel which
                the Purchaser or the relevant member of the Purchaser's Group
                proposes to instruct with respect to the Third Party Claim and
                such legal counsel shall be entitled to act in relation thereto
                (a) unless the Vendor reasonably objects in writing thereto
                within five Business Days of receipt by the Vendor of written
                notification of the identity of such legal counsel from the
                Purchaser or the relevant member of the Purchaser's Group and
                (b) if such legal counsel and the Purchaser or the relevant
                member of the Purchaser's Group agree with the Vendor in writing
                that, if the Vendor exercises its rights to assume conduct of
                the Third Party Claim under SUB-PARAGRAPH (C) below, the legal
                counsel will (if so requested by the Vendor) continue to act in
                relation to the Third Party Claim on the instruction of the
                Vendor;

         (ii)   in response to reasonable requests from the Vendor from time to
                time, it or the relevant member of the Purchaser's Group shall
                keep the Vendor informed of the progress of the Third Party
                Claim;

         (iii)  it or the relevant member of the Purchaser's Group shall provide
                the Vendor with copies of such documentation relating to the
                Third Party Claim as the Vendor may reasonably request at the
                cost of the Vendor;

         (iv)   it or the relevant member of the Purchaser's Group shall give
                the Vendor such opportunities as the Vendor may reasonably
                request to make written or reasonable oral representations
                regarding the conduct of the Third Party Claim;

         (v)    it or the relevant member of the Purchaser's Group shall give
                the Vendor written notice, of such period as is reasonable in
                the context of the Third Party Claim, the proposal and the
                circumstances in which it is made, of any proposal to settle or
                consent to the entry of any judgment in respect of the Third
                Party Claim, such notice to include reasonable details of the
                proposed settlement or consent to the entry of judgment; and

         (vi)   neither it nor the relevant member of the Purchaser's Group
                shall settle or consent to the entry of any judgment in respect
                of the Third Party Claim during the period set out in
                SUB-PARAGRAPH (B)(v) without the prior written consent of the
                Vendor.

(C)      At any time following the receipt by the Vendor of any notice of a
         Third Party Claim under SUB-PARAGRAPH (A) above and prior to the
         settlement, consent to the entry of judgment of, or non-appealable
         decision of a court of competent jurisdiction in respect of, such Third
         Party Claim, the Vendor shall be entitled, on written notice to the
         Purchaser and subject to the provisions of SUB-PARAGRAPHS (D) and (G)
         below, to assume conduct of the Third Party Claim in the name of the
         Purchaser or the appropriate member of the Purchaser's Group; EXCEPT
         that the Vendor shall not be



                                      129

         entitled to assume conduct of any Third Party Claim which is a criminal
         action or proceeding. For the avoidance of doubt, the Vendor shall be
         entitled to assume conduct of any non-criminal action or proceeding
         (pursuant and subject to the provisions of this SUB-PARAGRAPH (C))
         which arises out of the same facts and circumstances as a criminal
         action or proceeding.

(D)      The Vendor shall not be entitled to assume conduct of any Third Party
         Claim in the name of the Purchaser, any other member of the Purchaser's
         Group or otherwise unless the Vendor first (i) admits irrevocably and
         unconditionally (subject to the relevant provisions of SCHEDULE 7
         (Limitations on Liability)) to the Purchaser in writing and in a
         legally binding manner its liability under the Warranties in relation
         thereto, and (ii) undertakes in a deed to the Purchaser that it will
         indemnify the Purchaser and each other member of the Purchaser's Group
         against all liabilities, costs, damages or expenses incurred by any
         member of the Purchaser's Group (whether prior to, on or after the date
         of such deed) in respect of such Third Party Claim or the conduct
         thereof; PROVIDED that the limitations set out in SUB-PARAGRAPHS 1(A)
         and 1(B) of this SCHEDULE 7 and PARAGRAPH 6 of this SCHEDULE 7 shall
         apply to any liability of the Vendor under this SUB-PARAGRAPH (D)(ii)
         as if such liability were a Warranty claim for the purposes of those
         paragraphs.

(E)      Where the Vendor assumes the conduct of a Third Party Claim pursuant to
         the provisions of SUB-PARAGRAPH (C) above:

         (i)    the Purchaser undertakes that:

                (a)  neither it nor any other member of the Purchaser's Group
                     shall make any admission of liability, agreement or
                     settlement with any third party, or consent to the entry of
                     judgment, in relation to the Third Party Claim;

                (b)  it shall give, or cause to be given by the relevant members
                     of the Purchaser's Group, to the Vendor all such assistance
                     as the Vendor may reasonably require in avoiding,
                     disputing, resisting, mitigating or defending the Third
                     Party Claim, including, without limitation, such access to
                     the books and records of any member of the Purchaser's
                     Group, and to the premises and employees and professional
                     advisors of the Purchaser's Group, during Working Hours and
                     on reasonable advance notice, as the Vendor may reasonably
                     require; and

                (c)  it shall, and shall procure that each other member of the
                     Purchaser's Group shall, pass to the Vendor copies of all
                     notices or other documents received by the Purchaser or any
                     member of the Purchaser's Group in relation to the Third
                     Party Claim, in each case as soon as reasonably practicable
                     after receipt by the Purchaser or relevant member of the
                     Purchasers' Group thereof;

         (ii)   the Vendor undertakes that:



                                      130

                (a)  if it decides not to instruct the same legal counsel as
                     instructed by the Purchaser with respect to the Third Party
                     Claim (if any), it or the relevant member of the Vendor's
                     Group shall notify the Purchaser in writing of the legal
                     counsel which the Vendor proposes to instruct with respect
                     to the Third Party Claim and such legal counsel shall be
                     entitled to act in relation thereto (x) unless the
                     Purchaser reasonably objects in writing thereto within five
                     Business Days of receipt by the Purchaser of written
                     notification of the identity of such legal counsel from the
                     Vendor or the relevant member of the Vendor's Group and (y)
                     if such legal counsel and the Vendor or the relevant member
                     of the Vendor's Group agree with the Purchaser in writing
                     that, if the Purchaser exercises its rights under
                     SUB-PARAGRAPH (F) below, the legal counsel will (if so
                     requested by the Purchaser) continue to act in relation to
                     the Third Party Claim on the instruction of the Purchaser;

                (b)  in response to reasonable requests from the Purchaser from
                     time to time, it or the relevant member of the Vendor's
                     Group shall keep the Purchaser informed of the progress of
                     the Third Party Claim;

                (c)  it or the relevant member of the Vendor's Group shall
                     provide the Purchaser with copies of such documentation
                     relating to the Third Party Claim as the Purchaser may
                     reasonably request;

                (d)  it or the relevant member of the Vendor's Group shall give
                     the Purchaser such opportunities as the Purchaser may
                     reasonably request to make written or reasonable oral
                     representations regarding the conduct of the Third Party
                     Claim;

                (e)  neither it nor any relevant member of the Vendor's Group
                     shall take, permit or omit, or procure the taking,
                     permitting or omission of, any step or action in relation
                     to any Third Party Claim to the extent that (i) the Vendor
                     in good faith and acting reasonably considers, or (ii) the
                     Purchaser can demonstrate to the Vendor (acting reasonably
                     and in good faith), in each case, that the taking,
                     permitting or omission of the relevant step or action is
                     reasonably likely to have an adverse effect on any trading
                     relationship or the goodwill of any relevant member of the
                     Purchaser's Group or the US Business which would, in either
                     case, be material to the Transferring Business;

                (f)  without prejudice to the provisions of SUB-PARAGRAPH
                     (E)(iii), it or the relevant member of the Vendor's Group
                     shall give the Purchaser written notice, of such period as
                     is reasonable in the context of the Third Party Claim, the
                     proposal and the circumstances in which it is made, of any
                     proposal to settle or consent to the entry of judgment in
                     respect of the Third Party Claim, such notice to include
                     reasonable details of the proposed settlement or consent to
                     the entry of judgment; and



                                      131

                (g)  without prejudice to the provisions of SUB-PARAGRAPH E
                     (iii), neither it nor the relevant member of the Vendor's
                     Group shall settle or consent to the entry of judgment in
                     respect of the Third Party Claim during the period set out
                     in SUB-PARAGRAPH (E)(ii)(f) without the prior written
                     consent of the Purchaser.

         (iii)  the Vendor shall not be entitled to settle or consent to the
                entry of any judgment in respect of the Third Party Claim
                unless:

                (a)  such settlement or judgment provides for settlement or
                     relief solely in the form of monetary payment; or

                (b)  if the settlement or judgment is not of the type described
                     in SUB-PARAGRAPH (E)(iii)(a) above, without the prior
                     written consent of the Purchaser (such consent not to be
                     unreasonably withheld or delayed) and, for the purposes of
                     this PARAGRAPH E(iii)(b), it will be reasonable for the
                     Purchaser to withhold or delay its consent to a settlement
                     or judgment if such settlement or judgment is reasonably
                     likely to have an adverse effect on any trading
                     relationship or the goodwill of the relevant member of the
                     Purchaser's Group or the US Business which adverse effect
                     would be, in either case, material to the Transferring
                     Business.

(F)      Notwithstanding the provisions of SUB-PARAGRAPHS (C), (D) and (E)
         above, the Purchaser shall be entitled to take control of any Third
         Party Claim the conduct of which has been assumed by the Vendor in
         accordance with SUB-PARAGRAPH (C) above at any time after such
         assumption and prior to the settlement, consent to the entry of
         judgment of, or non-appealable decision of a court of competent
         jurisdiction in respect of, such Third Party Claim provided that the
         Purchaser:

         (i)    first waives irrevocably and unconditionally in writing and in a
                legally binding manner any and all claims which it, or any other
                member of the Purchaser's Group, may have against the Vendor or
                any other member of the Vendor's Group (other than, in respect
                of insurance matters, the Captive Insurer) in respect of such
                Third Party Claim under this Agreement or any of the Specified
                Agreements; and

         (ii)   undertakes in a deed that it will indemnify the Vendor and the
                relevant members of the Vendor's Group (other than, in respect
                of insurance matters, the Captive Insurer) against all
                liabilities, costs, damages or expenses incurred (whether prior
                to or after the date of such deed) by any member of the Vendor's
                Group (other than, in respect of insurance matters, the Captive
                Insurer) in respect of such Third Party Claim (including, for
                the avoidance of doubt, the costs and expenses incurred by the
                Vendor or any other member of the Vendor's Group (other than, in
                respect of insurance matters, the Captive Insurer) in conducting
                the Third Party Claim pursuant to the provisions of this
                PARAGRAPH 3).

(G)      If, in respect of a Third Party Claim, the Purchaser, or any other
         member of the Purchaser's Group, is entitled to make a claim under any
         policy of insurance (other than



                                      132

         an insurance claim with no reasonable prospect of success) such that
         the provisions of SUB-PARAGRAPH 5(A) apply to the matter giving rise to
         the Third Party Claim (an "INSURED THIRD PARTY CLAIM"), the provisions
         of SUB-PARAGRAPHS (B) to (F) shall be subject to the provisions of the
         relevant insurance policy or policies relating to such Insured Third
         Party Claim and the directions of the relevant insurer or insurers
         thereunder; PROVIDED that the Purchaser shall, and shall procure that
         the other members of the Purchaser's Group shall, and the Vendor shall,
         and shall procure that the other members of the Vendor's Group shall,
         comply with the provisions of SUB-PARAGRAPHS (B) to (F) to such extent
         as is permitted under the relevant insurance policy or policies with
         respect to the Insured Third Party Claim or as the relevant insurer or
         insurers thereunder may otherwise consent.

(H)      If, in relation to any claim for any breach of the Tax Warranties there
         is also a claim in respect of the same subject matter for a liability
         under the Tax Covenant, Clause 8 of the Tax Covenant shall govern the
         conduct of the relevant litigation and/or claim for breach of such Tax
         Warranties in precedence to and notwithstanding the provisions of this
         PARAGRAPH 3.

4.       SINGLE RECOVERY

(A)      No liability shall attach to the Vendor, the Share Sellers, the US
         Business Seller, the IP Assets Sellers or any of them by reason of any
         breach of any of the Warranties or pursuant to PARAGRAPH 16 of SCHEDULE
         8 to the extent that the same loss has been recovered by the Purchaser
         or any other Designated Purchaser under the Tax Covenant or any other
         Warranty or term of this Agreement or the Specified Agreements and,
         accordingly, the Purchaser and any other Designated Purchaser may only
         be entitled to recover once in respect of the same loss.

(B)      (i)    In calculating the liability of the Vendor, the Share Sellers,
                the US Business Seller and the IP Assets Sellers for any breach
                of the Warranties or pursuant to PARAGRAPH 16 of SCHEDULE 8
                there shall be taken into account any repayment in respect of
                Tax or any Relief arising as a result of the matter giving rise
                to such liability which the Purchaser or any member of the
                Purchaser's Group obtains and utilises on or before the date of
                calculating such liability.

         (ii)   To the extent that the Purchaser (or the relevant member of the
                Purchaser's Group) obtains and utilises any repayment in respect
                of Tax or any Relief arising as a result of the matter giving
                rise to the liability of the Vendor, the Share Sellers, the US
                Business Seller or the IP Assets Sellers for any breach of the
                Warranties or pursuant to PARAGRAPH 16 of SCHEDULE 8, the
                Purchaser (or the relevant member of the Purchaser's Group)
                shall, except to the extent that such utilisation has been taken
                into account in calculating the liability of the Vendor, the
                Share Sellers, the US Business Seller or the IP Assets Sellers
                pursuant to PARAGRAPH (i) of this SUB-PARAGRAPH (B), remit to
                the Vendor, within 15 Business Days of actual receipt, an amount
                equal to so much of the economic benefit from that repayment in
                respect of Tax or Relief which the Purchaser (or the relevant
                member of the Purchaser's Group) has actually received; PROVIDED
                that nothing in this SUB-PARAGRAPH (B)(ii) shall restrict the



                                      133

                ability or discretion of the Purchaser (or the relevant member
                of the Purchaser's Group) to order its Tax affairs in any way
                which it sees fit and to keep its Tax affairs confidential. Any
                question concerning whether the Purchaser (or the relevant
                member of the Purchaser's Group) has actually realised any such
                economic benefit or the quantum and timing of such benefit shall
                be determined by the auditors for the time being of the
                Purchaser (or the relevant member of the Purchaser's Group).

(C)      No liability shall attach to the Vendor, the Share Sellers, the US
         Business Seller, the IP Asset Sellers or any of them by reason of any
         breach of the Warranty set out in PARAGRAPH 4(F) of SCHEDULE 6 to the
         extent (and in respect of the period) that the Vendor or any other
         member of the Vendor's Group provides to the relevant Company or
         Designated Purchaser such goods, services or facilities as shall have
         given rise to the breach of such Warranty for the period of 6 months
         from the Completion Date (and, if the relevant Company or Companies or
         other member of the Purchasers' Group, having unsuccessfully used all
         reasonable endeavours to cease the use of such goods, services or
         facilities (as appropriate) by the end of such 6 month period, upon
         written notice from the Purchaser to the Vendor, a further 6 months
         following the expiry of such 6 month period), on the same basis as such
         goods, services or facilities were provided to the relevant Company or
         Companies or to any other member of the Vendor's Group in respect of
         the Transferring Business immediately prior to the Completion Date.

5.       RECOVERY FROM INSURERS AND OTHER THIRD PARTIES

(A)      If, in respect of any matter which would give rise to a claim under the
         Warranties any member of the Purchaser's Group is entitled to claim
         under any policy of insurance (other than an insurance claim with no
         reasonable prospect of success) then, having notified the Vendor of the
         claim in writing in accordance with PARAGRAPH 2, the Purchaser shall
         not further pursue that claim under the Warranties unless and until the
         appropriate member of the Purchaser's Group shall have made a claim
         against its insurers and used all reasonable endeavours to pursue such
         insurance claim including where reasonable and appropriate commencing
         and prosecuting proceedings against insurers. There shall be no
         liability under the Warranties to the extent of the amount recovered
         under any such insurance claim except to the extent:

         (i)    of the reasonable costs and expenses and any Taxation incurred
                or suffered by any member of the Purchaser's Group in connection
                with the recovery; and/or

         (ii)   that the future insurance costs of the Purchaser or any other
                member of the Purchaser's Group are increased by the matter
                giving rise to the insurance claim or the claim itself.

(B)      If having notified the Vendor of the relevant claim in writing in
         accordance with PARAGRAPH 2 and (a) having used all reasonable
         endeavours to pursue an insurance claim as contemplated by
         SUB-PARAGRAPH (A), or (b) by the second anniversary of the notification
         by the Purchaser to the Vendor in writing of the relevant Warranty
         claim, the Purchaser (or the relevant other member of the Purchaser's
         Group) shall not have recovered the full amount of its loss in respect
         of the relevant matter, the provisions of



                                      134

         PARAGRAPH 2 and PARAGRAPH 5 shall not preclude it from pursuing any
         claim under the Warranties in respect of such matter for the amount of
         the loss not recovered from insurers and the proviso to PARAGRAPH 2
         shall not apply to such claim; PROVIDED that in the circumstances set
         out in (b) above, the provisions of this SUB-PARAGRAPH 5(B) shall not
         limit in any way the obligations of the Purchaser or any member of the
         Purchaser's Group under SUB-PARAGRAPH (A) to pursue such insurance
         claim. The provisions of SUB-PARAGRAPH (A) shall not prejudice the
         ability of the Purchaser to recover interest in respect of any claim
         under the Warranties.

(C)      Where the Purchaser or any member of the Purchaser's Group is at any
         time entitled to recover from some third party, not being an insurer or
         the Vendor or any member of the Vendor's Group, any sum in respect of
         any matter giving rise to a claim under the Warranties, the Purchaser
         shall, and shall procure that the member of the Purchaser's Group
         concerned shall, take all reasonable steps to make such recovery and in
         the event that the Purchaser or any member of the Purchaser's Group
         shall recover any amount from such third party prior to any member of
         the Vendor's Group paying to the Purchaser or any member of the
         Purchaser's Group any amount pursuant to the relevant claim under the
         Warranties, the amount of the claim under the Warranties shall be
         reduced by the amount recovered (except to the extent that such
         recovery had been taken into account in the formulation of the claim
         under the Warranties and except to the extent of the reasonable costs
         and expenses and any Taxation incurred or suffered by any member of the
         Purchaser's Group in connection with the recovery), provided that the
         Purchaser shall not be required to commence any legal proceedings where
         either:

         (i)    the Purchaser has effected a valid legal assignment of all its
                rights in relation to the relevant claim to the Vendor; or

         (ii)   where SUB-PARAGRAPH (C)(i) does not apply, the Vendor has not as
                soon as is reasonably practicable notified the relevant party
                against whom such proceedings are brought that such proceedings
                are being brought at the instruction of the Vendor.

         For the avoidance of doubt, the provisions of this SUB-PARAGRAPH (C)
         shall not require the Purchaser or any member of the Purchaser's Group
         to take any steps to recover sums from a third party prior to taking
         any action against the Vendor, the Share Seller, the US Business
         Seller, the IP Assets Sellers or any of them and shall not require the
         Purchaser or any member of the Purchaser's Group to take, permit or
         omit from taking any step or action to recover sums from a third party
         to the extent that the taking, permitting or omission of the relevant
         step or action would have an adverse effect on any trading relationship
         or the goodwill of any relevant member of the Purchaser's Group or the
         US Business which would, in either case, be material to the
         Transferring Business.

(D)      If any member of the Vendor's Group pays at any time to the Purchaser
         or any member of the Purchaser's Group an amount pursuant to a claim in
         respect of the Warranties and the Purchaser or relevant member of the
         Purchaser's Group subsequently recovers from a third party (including,
         for the avoidance of doubt, any insurer, but excluding the



                                      135

         Vendor or a member of the Vendor's Group) any sum in respect of any
         matter giving rise to such claim, the Purchaser shall, and shall
         procure that the relevant member of the Purchaser's Group shall, repay
         to the relevant member of the Vendor's Group the lesser of (i) the
         amount paid by the relevant member of the Vendor's Group to the
         Purchaser or other member of the Purchaser's Group, and (ii) the sum
         (including interest (if any)) recovered from such third party LESS (a)
         the reasonable costs and expenses and any Taxation incurred or suffered
         by the relevant member of the Purchaser's Group in connection with such
         recovery and (b) any amount (other than insurance premium) paid to any
         insurer pursuant to any rights of subrogation or otherwise under any
         relevant insurance policy or policies in connection with such recovery.

6.       ACTS OF PURCHASER

(A)      No claim shall lie against the Vendor, the Share Sellers, the US
         Business Seller, the IP Assets Sellers or any of them under or in
         relation to the Warranties or pursuant to PARAGRAPH 16 of SCHEDULE 8 to
         the extent that such claim is attributable to:

         (i)    any voluntary act, omission, transaction or arrangement carried
                out at the written request of or with the written consent of the
                Purchaser or by a member of the Purchaser's Group (other than
                the Companies) before Completion;

         (ii)   any voluntary act or transaction carried out or entered into by
                the Purchaser or by a member of the Purchaser's Group on (save
                for the taking of any steps set out in SCHEDULE 5 (Completion))
                or after Completion unless such act or transaction (a) is
                carried out or entered into by the Purchaser or another member
                of the Purchaser's Group in the ordinary course of business, (b)
                is required to be carried out or entered into by law or
                regulation in any relevant jurisdiction, or (c) is carried out
                or entered into pursuant to a legally binding commitment entered
                into by a Company or a member of the Vendor's Group in respect
                of the US Business prior to Completion; or

         (iii)  any failure by the Purchaser or any other member of the
                Purchaser's Group to take, after Completion, an action which is
                required of it (a) by law or regulation in any relevant
                jurisdiction, or (b) otherwise under any legally binding
                contract or agreement entered into by any Company or any member
                of the Vendor's Group in respect of the US Business and (in the
                case of (b) only) listed in the Data Room Index or forming part
                of the Disclosure Bundle.

(B)      Neither the Vendor, the Share Sellers, the US Business Seller, the IP
         Assets Sellers nor any of them shall be liable for any breach of any
         Warranty or pursuant to PARAGRAPH 16 of SCHEDULE 8 which would not have
         arisen but for any change after Completion in any accounting basis on
         which any member of the Purchaser's Group values its assets or in any
         accounting basis, method, policy or practice of any member of the
         Purchaser's Group.



                                      136

7.       THE ACCOUNTS, THE MANAGEMENT ACCOUNTS AND THE COMPLETION ACCOUNTS

         No matter shall be the subject of a claim under the Warranties or
         pursuant to PARAGRAPH 16 of SCHEDULE 8 to the extent that allowance,
         provision or reserve in respect of such matter shall have been
         specifically identified in the Accounts or the Management Accounts or
         to the extent such matter is taken into account in the calculation of
         the Working Capital Amount.

8.       RETROSPECTIVE LEGISLATION

         No liability shall arise in respect of any breach of any of the
         Warranties or pursuant to PARAGRAPH 16 of SCHEDULE 8 to the extent that
         liability for such breach occurs or is increased directly or indirectly
         as a result of (i) any legislation not in force on or prior to the date
         of this Agreement or (ii) the withdrawal of any published
         extra-statutory concession or other agreement or (in relation only to
         the Tax Warranties) arrangement currently granted by or made with any
         governmental authority, or (iii) any change after the date of this
         Agreement of any published interpretation or (in relation only to the
         Tax Warranties) published application of any legislation or (in
         relation only to the Tax Warranties) in the enforcement policy or
         practice of the relevant authorities, or (iv) the withdrawal of any
         published extra-statutory concession or any other agreement or (in
         relation only to the Tax Warranties) arrangement with any Tax Authority
         (whether or not having the force of law) currently granted by or made
         with any Tax Authority.

9.       TAXATION

(A)      Without prejudice to the generality of PARAGRAPH 8 above, the Vendor,
         the Share Sellers, the US Business Seller and the IP Assets Sellers
         shall not be liable in any event in respect of any breach of the
         Warranties if such breach or claim would not have occurred or arisen
         but for any change in the basis of, method of calculation of, or
         increase in the rate or rates of Taxation or changes in the practice of
         the Inland Revenue or other Tax Authority announced (or if not so
         announced in advance, being made) after the date hereof or the
         withdrawal of any published extra-statutory concession currently
         granted by any Tax Authority.

(B)      None of the Vendor, the Share Sellers, the US Business Seller or the IP
         Assets Sellers shall be liable for any claim to the extent that it
         arises out of or is increased by virtue of a voluntary disclaimer by
         any Company after Completion of any Relief available to any Company
         (other than any such disclaimer made at the request of or with the
         consent of the Vendor).

(C)      None of the Vendor, the Share Sellers, the US Business Seller or the IP
         Assets Sellers shall be liable in respect of any claims in respect of
         any breach of the Tax Warranties (a "TAX CLAIM") if and to the extent
         that any pre-Completion Relief not taken into account in computing the
         provision for Tax in the Accounts is available or is made available to
         relieve or otherwise mitigate the liability of the Company for Tax
         which is the subject matter of such Tax Claim.



                                      137

(D)      None of the Vendor, the Share Sellers, the US Business Seller or the IP
         Assets Sellers shall be liable in respect of any breach of the Tax
         Warranties if such liability would have been excluded under the
         provisions of clause 3 of the Tax Covenant had the relevant liability
         been a Tax Liability for the purposes of the Tax Covenant.

10.      DISCLOSURE

         The Purchaser shall not be entitled to claim that any fact, matter or
         circumstance causes any of the Warranties to be breached to the extent
         that such fact, matter or circumstance is fairly disclosed in the
         Disclosure Letter or in any document contained in the Disclosure Bundle
         or listed in the Data Room Index; PROVIDED that the only disclosures
         that shall be relevant to the Warranty set out in PARAGRAPH 8(E) of

         in respect of any claim under the Warranties or pursuant to PARAGRAPH
         16 of SCHEDULE 8 shall be deemed to be a reduction of the Cash
         Consideration payable by the Purchaser (on behalf of the relevant
         Designated Purchaser) and such reduction shall be allocated to the
         greatest extent possible to the particular Shares, US Business Assets
         or IP Assets to which the claim relates.

12.      FRAUD

         None of the provisions of this SCHEDULE 7 (other than PARAGRAPH 11)
         shall apply in respect of any claim under the Warranties or under the
         Tax Covenant where the giving of the relevant Warranties or the
         relevant provision of the Tax Covenant or the preparation of the
         relevant provisions of the Disclosure Letter involve or involved fraud
         on the part of the Vendor or another member of the Vendor's Group.

13.      MITIGATION

         Nothing in this Agreement shall affect the obligation of the Purchaser
         or any Designated Purchaser under the general law to mitigate the loss
         in respect of which it may be entitled to make any claim under the
         Warranties.

         Liability) shall apply to:

         (i)    the Warranties set out in PARAGRAPH 2 (Capacity of the Vendor's

                                             he would have been entitled to

                                             4(B)(i), once such an election has
                                             been made, this obligation of the

                           continue that practice; provided that the Purchaser
                           shall, subject to applicable law, have the same
                           rights of variation and discontinuance of that
                           practice as the relevant

                           the Completion Date.

                  (c)      benefits in the UPF and benefits to be provided or
                           procured to be provided by the Purchaser shall be
                           valued on the basis of the same actuarial method and
                           assumptions as are set out in the statement from the
                           Vendor's Actuary referred to in paragraph 8, modified
                           to such extent as may be agreed in writing by the
                           Vendor's Actuary and the Purchaser's Actuary and the
                           procedure referred to in paragraph 10(D) to (G)
                           inclusive shall apply if any such modification is not
                           so agreed.

                  (d)      whether or not a transfer is made to the Purchaser's
                           Pension Scheme in respect of past service benefits,
                           equivalent benefits in respect of the service of each
                           Relevant Employee for the period referred to in
                           paragraph 4(B)(i) must vest on the same or shorter
                           timescale and at least in the same circumstances as
                           if the Relevant Employee concerned had continued to
                           be an active member of the UPF for so long as he
                           remains employed by a member of the Purchaser's Group
                           (whether or not continuing to accrue benefits under
                           the Purchaser's Pension Scheme).

                  (e)      equivalent benefits in respect of service prior to
                           and on and after the Completion Date must also be of
                           a type and form approved by the Vendor. For this
                           purpose, it is agreed that it will be reasonable for
                           the Vendor's Actuary not to approve money purchase
                           benefits in place of benefits under the UPF and 1999
                           SERA.

                  (f)      where benefits are provided under the UPF or 1999
                           SERA on the death or disability of a Relevant
                           Employee or his spouse, child or dependant,
                           equivalent benefits must be provided on such events
                           which are payable in circumstances and under
                           conditions which are not materially less favourable
                           to the beneficiary concerned as those which would
                           have applied had the death or disability occurred
                           whilst the beneficiary was a beneficiary of the UPF
                           or 1999 SERA under the provisions of the UPF or 1999
                           SERA in force immediately prior to the Completion
                           Date.

         (iii)    Except for any contributions due in respect of a service
                  credit under the UPF, the Purchaser shall procure that, in the
                  satisfaction of its obligation under paragraph 4(B)(i),
                  compulsory contributions shall not be payable by a Pensionable
                  Employee, except to the extent otherwise expressly agreed in
                  writing by that Pensionable Employee, at a rate greater than
                  the rate (if any) at which:

                                      148


                  (a)      he pays compulsory contributions at the Completion
                           Date, for a period of 1 year from the Completion Date
                           or, if shorter, the period expiring on the date on
                           which he is required to contribute to the UPF under
                           the provisions of the UPF, if he is then an active
                           member of the UPF, or on which he would have been
                           required to contribute to the UPF under the
                           provisions of the UPF, had he then been an active
                           member of the UPF; and

                  (b)      he could have been required to contribute to the UPF
                           under the provisions of the UPF in force immediately
                           prior to the Completion Date but for any surplus or
                           deficit in the UPF, for the remainder of the period
                           referred to in paragraph 4(B)(i) after the expiry of
                           the period in (a) above.

         (C)      The obligations under paragraph 4(B) and paragraph 5(A) shall
                  continue in force even if the Purchaser disposes of a member
                  of the Purchaser's Group or all or any part of the business
                  thereof and accordingly the Purchaser shall procure that the
                  acquiror concerned honours the obligations under paragraph
                  4(B) and paragraph 5(A) in respect of each Transferring Member
                  (as such definition is extended in paragraph 4(B)(i))
                  concerned in such a disposal.

         (D)

                  (i)      The Purchaser shall procure that the Purchaser's
                           Actuary shall notify the Vendor's Actuary in writing
                           of the benefits which it is proposed the Purchaser
                           will provide or procure to be provided in accordance
                           with paragraph 4(B).

                  (ii)     The Vendor's Actuary, on receipt of notification in
                           accordance with paragraph 4(D)(i), shall review the
                           benefits to be provided and shall determine by notice
                           in writing to the Purchaser's Actuary whether the
                           benefits proposed to be provided comply with the
                           requirements of paragraph 4(B).

                  (iii)    If the Purchaser's Actuary does not agree with the
                           Vendor's Actuary's determination referred to in
                           paragraph 4(D)(ii), the disagreement shall be
                           resolved in accordance with the procedure referred to
                           in paragraph 10(D) to (G) inclusive with all
                           necessary changes.

         (E)      Any announcement to be issued by the Vendor or a member of the
                  Purchaser's Group in relation to benefits the subject of this
                  paragraph 4 or paragraph 5 must be consistent with the terms
                  of this paragraph 4 and paragraph 5 and, prior to the issue of
                  any such announcement, the Vendor or, as the case may be, the
                  Purchaser, shall provide to the other a copy of the intended
                  announcement and shall not issue it without prior consultation
                  with the other.

         (F)      The Purchaser's agreement to the provisions of this paragraph
                  4 and paragraph 5 is given by the Purchaser on the express
                  understanding that, if the Purchaser

                                      149


                  is in breach of any of such provisions, the Vendor may, at its
                  absolute discretion, and without limitation, seek to procure
                  compliance with such provisions by the Purchaser by applying
                  to the court for damages and/or specific performance.

5.       PURCHASER TO OFFER BENEFITS FOR PAST SERVICE AND TO GIVE OTHER
         UNDERTAKINGS

         (A)      The Purchaser shall procure that each Relevant Employee who
                  has not immediately before the Scheme Change Date:

                  o        ceased to be in employment of the Purchaser, or

                  o        attained normal retirement age in the UPF,

                  shall, in respect of pensionable service up to the day before
                  the Scheme Change Date, have the option of transferring,
                  subject to:

                  (a)      the UPF agreeing to transfer the Relevant Capital Sum
                           as adjusted in accordance with paragraph 11(A), OR

                  Relevant Employee under the Purchaser's Pension Scheme in
                  respect of pensionable service up to the day before the Scheme
                  Change Date will be no less favourable overall (as agreed or
                  determined in accordance with paragraph 4(D)) than the
                  benefits for and in respect of that Relevant Employee until
                  then provided under the UPF.

         (B)      In determining, for the purpose of paragraph 5(A), whether
                  benefits under the Purchaser's Pension Scheme are "no less
                  favourable" than benefits under the UPF, the provisions of
                  paragraph 4(B)(ii) shall apply with all necessary changes.

         (C)      The Purchaser shall procure before the Payment Date that:

                  (i)      the Purchaser's Pension Scheme delivers to the UPF an

                                    respect of the Transferring Members;

                           (b)      subject to receipt of the amount referred to
                                    in paragraph 11(A) OR to a payment being
                                    made pursuant to paragraph 12(A) to provide
                                    benefits to the Transferring Members in

                                    o        any undertakings given by the UPF
                                             to the Board of Inland Revenue;

                                             under that Act); and

                                             contracting-out requirements made
                                             under that or any other Act),

                                    in each case to the extent applicable;

                  (ii)     the employer of the Transferring Members in question
                           is named in a contracting-out certificate issued for

                           Change Date (other than the liabilities in respect of
                           the benefits of the Transferring Members until then
                           provided under the UPF).

         (D)      The Purchaser shall procure that the notices to be issued to
                  Relevant Employees in respect of the option referred to in
                  paragraph 5(A) are in terms which require consents to a
                  transfer to be given by a date agreed between the Vendor and
                  the Purchaser.

6.       VENDOR'S OBLIGATIONS DURING THE HOLDING PERIOD

         (A)      The Vendor shall use all reasonable endeavours to ensure that
                  during or in respect of the Holding Period:

                  (i)      the UPF and 1999 SERA shall not be terminated, and

                  (ii)     no amendments to the UPF or 1999 SERA shall be made
                           which will diminish or otherwise affect the benefits
                           of the Relevant Employees,

                  without the prior written agreement of the Purchaser.

         (B)      The Purchaser's agreement referred to in paragraph 6(A)
                  shall not be unreasonably withheld or delayed and if
                  withheld or delayed the Vendor shall be entitled to specify
                  by not less than one month's written notice to the Purchaser

<Page>
                                      151


                  that the Holding Period shall terminate on such date as shall
                  be specified in the said notice.

7.       RESTRICTION ON INCREASES TO PENSIONABLE PAY; PURCHASER TO COMPLY WITH
         CERTAIN OTHER CONDITIONS

         (A)      The Purchaser undertakes that it shall procure that the UK
                  Company will not increase the Pensionable Pay of any Relevant
                  Employee during the Holding Period save that the annual
                  pensionable salary of any Relevant Employee may be increased
                  by up to the percentage (pro-rated to reflect the length of
                  the Holding Period) assumed for annual pensionable salary
                  increases in the Statement from the Vendor's Actuary comprised
                  in Annex A to this Schedule (such percentage being reduced by
                  the percentage amount of any increase awarded since the last
                  annual pensionable salary increase awarded prior to the
                  Completion Date) or such greater percentage agreed in writing
                  by the Vendor and the Purchaser.

         (B)      The Purchaser shall procure that the UK Company shall:

                  (i)      comply during the Holding Period in all respects with
                           the provisions of the UPF;

                  (ii)     not do or omit to do during the Holding Period any
                           act or thing whereby the approval of the UPF as an
                           exempt approved scheme or as a contracted-out scheme
                           would or might be prejudiced;

                  (iii)    not exercise any power, right or discretion conferred
                           on the UK Company by the UPF except on such terms
                           (whether as to payment of additional contributions to
                           the UPF or otherwise) as the Vendor may agree;

                  (iv)     complete promptly all contracting-out elections and
                           issue promptly all contracting-out notices which the
                           Vendor may reasonably require to be completed or
                           issued;

                  (v)      supply to the Vendor and to the UPF copies of any
                           notices to be issued to the Relevant Employees in
                           connection with the matters contemplated by this Part
                           A of this Schedule before they are issued to the
                           Relevant Employees;

                  (vi)     procure that no such notices as are referred to in
                           paragraph 7(B)(v) are issued to the Relevant
                           Employees until the benefits to be provided or
                           procured to be provided by the Purchaser in
                           accordance with paragraphs 4 and 5 have been agreed
                           or determined in accordance with those paragraphs;
<Page>
                                      152


                  (vii)    use its best endeavours to help the Vendor and the
                           UPF meet any statutory obligations which relate to
                           the Relevant Employees during the Holding Period;

                  (viii)   give the notice required under Clause 23(b)(i) of the
                           Trust Deed of the UPF to terminate its participation
                           in the UPF with effect from the day before the Scheme
                           Change Date; and

                  (ix)     return the forms of consent referred to in paragraph
                           5(D) to the UPF.

8.       METHOD OF CALCULATION OF THE RELEVANT CAPITAL SUM

         (A)      The Relevant Capital Sum shall be calculated as the sum of:

                  (i)      the transfer payment in respect of the Transferring
                           Members, which is:

                           (a)      the amount as at the Completion Date
                                    calculated in accordance with the basis set
                                    out in the Statement from the Vendor's
                                    Actuary comprised in Annex A to this
                                    Schedule;

                           (b)      adjusted in respect of the period from the
                                    Completion Date to 20th August, 2001 by
                                    reference to interest at the rate of 7.5 per
                                    cent. per annum to give its value as at 20th
                                    August, 2001;

                           (c)      multiplied by the Timing Adjustment for the
                                    period from and including 20th August, 2001
                                    to and excluding the Scheme Change Date, and

                  (ii)     the Net Relevant Contributions paid to the UPF in
                           respect of Transferring Members during the Holding
                           Period, each such Net Relevant Contribution being
                           multiplied by the Timing Adjustment applicable to the
                           period from and including the date of payment of the
                           Net Relevant Contribution to and excluding the Scheme
                           Change Date.

         (B)      In calculating the Relevant Capital Sum it shall be assumed
                  there is no obligation to equalise benefits (to the extent not
                  already equalised under the UPF) under Article 141 including,
                  without limitation, accrued rights to guaranteed minimum
                  pensions.

                  Purchaser's Actuary the Relevant Capital Sum as at the
                  Completion Date (ignoring any adjustments under paragraph
                  8(A)(i)(b) and (c) and 8(A)(ii) and assuming that all Relevant

         (C)

                  (i)      The Purchaser's Actuary shall review the computation

                  by the President for the time being of the Institute of
                  Actuaries at the instance of the party first applying to him.

         (A)      Subject to the conditions in paragraph 11(A) (i), (ii) and
                  (iii) having been satisfied, if the UPF does not the full
                  amount referred to in paragraph 11(A) to the Purchaser's

                  (A-B) + C

                  where

                  A =      the higher of:

                  o        105 per cent. of the Relevant Capital Sum (adjusted
                           by the Timing Adjustment for the period from and
                           including the day before the Scheme Change Date to
                           and including the day before the Payment Date); and

                  o        an amount calculated by the Vendor's Actuary as

                           suitable for payment on Payment Date,

                  B =     the value of the amount (if any) paid by the UPF to
                          the Purchaser's Pension Scheme (adjusted by the Timing
                          Adjustment for the period from and including the date

                          the period from and including the Payment Date to and
                          excluding the date of payment;

                  The amount of the Shortfall Payment shall be determined by the

                  default of agreement, be determined under paragraph 10.

         (B)

                  (i)      On receipt of the Shortfall Payment, the Purchaser
                           shall promptly pay an amount, or procure that the UK
                           Company shall promptly pay an amount, equal to (A -
                           B) + C (as defined above) into the Purchaser's
                           Pension Scheme (the "SHORTFALL CONTRIBUTION").

                  (ii)     If, in respect of the Shortfall Contribution, the
                           Purchaser obtains (in whole or in part) for the
                           accounting period for which a payment equal to

                           the Shortfall Contribution is paid into the
                           Purchaser's Pension Scheme (or for any future
                           accounting period) a deduction for part (or the
                           whole) of that payment which results in a Reduction
                           in Taxable Profits for the purposes of corporation
                           tax:

                           o        in the accounting period (or accounting
                                    periods) in which that deduction is obtained
                                    or,

                           o        in a case where that deduction exceeds the
                                    available taxable profits for the said
                                    accounting period (or any of the said
                                    accounting periods) but gives rise to a tax
                                    loss or other tax relief that is eligible to
                                    be carried forward for offset against future
                                    taxable profits, in any future accounting
                                    period (or future accounting periods) in
                                    which such offset is obtained,

                           the Purchaser shall pay to the Vendor so far as
                           possible by way of repayment of the Cash
                           Consideration payable in respect of the Shares of
                           Unipath Limited an amount equal to:

                           o        the aggregate amount by which the Shortfall
                                    Contribution reduces the said taxable
                                    profits in the accounting period (or
                                    accounting periods) in question,

                           multiplied by

                           o        the marginal rate of tax applicable to the
                                    Purchaser for the accounting period (or, as
                                    the case may be, for each of the accounting
                                    periods) in which the deduction is obtained
                                    or (as the case may be) the tax loss or
                                    other tax relief arising from that deduction
                                    is utilised.

                  (iii)    The Purchaser shall procure that a Reduction in
                           Taxable Profits in respect of the Shortfall
                           Contribution is obtained in priority to any Reduction
                           in Taxable Profits which could be obtained in respect
                           of any other matter with a view to ensuring that full
                           payment is made under (ii) above to the Vendor as
                           soon as practicable after the Shortfall Contribution
                           is paid to the Purchaser's Pension Scheme.

                  (iv)     Any payment under (ii) above shall be made by the
                           Purchaser forthwith upon the date on which tax would
                           otherwise have been paid if it had not been for the
                           said Reduction in Taxable Profits (or, if there is
                           more than one date on which the relevant amount of
                           tax would otherwise have been paid, whether by
                           instalments or otherwise, the earliest of such
                           dates).

                  (v)      For the purpose of this paragraph (B) a "REDUCTION IN
                           TAXABLE PROFITS" includes not only a reduction in the
                           taxable profits of the Purchaser but also a reduction
                           in the taxable profits for any accounting period of
                           any member of any group or consortium to which any
                           tax loss or other tax relief arising from or
                           attributable to the payment by the

                           Contribution is surrendered by way of group relief or
                           consortium relief in accordance with the provisions
                           of ss.402-413, Income and Corporation Taxes Act 1988.

13.      VOLUNTARY CONTRIBUTIONS

         Notwithstanding the foregoing, the Voluntary Fund within the UPF and
         the benefits payable or prospectively or contingently payable therefrom
         and the contributions payable thereto shall be disregarded in
         determining the Relevant Capital Sum except that there shall be added
         to the Relevant Capital Sum that part of the Voluntary Fund which is
         attributable to those Transferring Members who join the Purchaser's
         Pension Scheme on the Scheme Change Date and who agree to the transfer
         of their Voluntary Fund.

14.      ADJUSTMENTS IN RESPECT OF SENIOR MANAGERS

         The following amendments shall apply in respect of the Senior Managers:

         (A)      in addition to the contributions required in paragraph 3, the
                  Purchaser shall procure that the UK Company shall, whilst the
                  UK Company remains a participating employer pursuant to
                  paragraph 2, pay to Unilever UK Central Resources Limited 7%
                  of Senior Managers' Pensionable Pay (as defined in the
                  governing documentation of 1999 SERA) plus the amount of any
                  VAT due thereon, as if that amount represented contributions
                  in respect of such Senior Managers,

         (B)      the letter issued to Senior Managers providing supplementary
                  retirement and death benefits shall be regarded as part of the
                  UPF for the purpose of paragraphs 4,5,6,7 and 8 (and
                  therefore, for the avoidance of doubt, for the purpose of
                  paragraph 12) which shall therefore be read as if reference to
                  the UPF in those paragraphs were also references to 1999 SERA
                  and the references to Net Relevant Contributions in paragraph
                  8(A)(ii) shall include any contributions referred to in (A)
                  above paid in respect of a Transferring Member,

         (C)      the Purchaser shall enter into an agreement with each Relevant
                  Employee who is a Senior Manager in a form satisfactory to the
                  Vendor to achieve the purposes of this paragraph 14, and

         (D)      the Purchaser must procure that the Purchaser's Pension Scheme
                  which provides benefits in respect of a transfer of benefits
                  from 1999 SERA and in respect of service after the Completion
                  Date which are equivalent to benefits under 1999 SERA is, to
                  the extent such benefits are capable of tax approval, funded.

15.      NO ASSISTANCE TO BE GIVEN BY THE PURCHASER

         (A)      The Purchaser undertakes to take no action and to give no
                  assistance whether directly or indirectly to any person in any
                  manner which would or might result in

                                      158


                  the UPF having to pay a larger amount than the amount payable
                  under paragraph 11 to the Purchaser's Pension Scheme (for this
                  purpose, the words "105 per cent." in paragraph 11 being
                  substituted by the words "100 per cent."). The Purchaser
                  agrees that this undertaking extends to the Purchaser and any
                  other company directly or indirectly controlled or connected
                  with the Purchaser and applies both during and after the
                  Holding Period.

         (B)      The Purchaser undertakes to the Vendor that:

                  (i)      before and on and after the Payment Date the trust
                           deed and rules of the Purchaser's Pension Scheme will
                           include a condition that the Purchaser's approval is
                           required to the acceptance of any transfer payment to
                           be made by the UPF to the Purchaser's Pension Scheme,
                           and

                  (ii)     it will not give such approval if the total payment
                           proposed to be made to the Purchaser's Pension Scheme
                           by the UPF exceeds the amount payable under paragraph
                           11.

16.      VENDOR'S UNDERTAKINGS

         (A)      The Vendor agrees to indemnify and keep indemnified each of
                  the Purchaser, the Purchaser's Pension Scheme and the UK
                  Company against any losses, liabilities, costs, damages or
                  expenses to make any payments to the UPF beyond the rate of
                  16.7% pursuant to paragraph 3(A)(i), including and pursuant to
                  section 75 of the Pensions Act 1995. This indemnity shall not
                  extend to any liability of the Purchaser to make contributions
                  to the UPF as a result of its breach of paragraph 7(A).

         (B)      The Vendor will indemnify the Purchaser against any liability
                  to provide retirement benefits on the grounds that a UK
                  Employee or former employee of the UK Company was denied
                  access to the UPF or the Unilever Superannuation Fund in
                  breach of Article 141 prior to the Completion Date to the
                  extent such claim relates to the period prior to the
                  Completion Date.

17.      AGREEMENT TO ACT PROMPTLY

         The Purchaser and the Vendor will use their respective reasonable
         endeavours to ensure that they comply with all their obligations under
         this Schedule promptly.

18.      PENSION WARRANTIES

         (A)      Save in respect of:

                  o        the UPF;

                  o        the letters issued to Senior Managers referred to in
                           paragraph 14;

                  o        the UK state scheme;

                  o        any arrangement the sole purpose of which is to
                           provide benefits on injury or death; and

                  o        any arrangement which only provides death benefits
                           secured by an insurance policy,

         no member of the Vendor's Group nor the UK Company (in this paragraph
         18, the "EMPLOYER"):

                  (i)      has any obligation (whether legally binding or not)
                           to:-

                           (a)      pay any pension; or

                           (b)      make any other payment on or after
                                    retirement or death; or

                           (c)      otherwise to provide "relevant benefits"
                                    (within the meaning of Section 612 of The
                                    Income and Corporation Taxes Act 1988)

                           to, or in respect of, any UK Employee (or spouse or
                           dependant of any of them) such UK Employee; and

                  (ii)     is a party to or obligated to contribute to any
                           scheme or arrangement having as its purpose, or one
                           of its purposes, the making of any such payments or
                           the provision of any such benefits to, or in respect
                           of, any UK Employee (or spouse or dependant of any of
                           them).

         (B)      Full details of the UPF insofar as it relates to the Relevant
                  Employees are comprised in the Data Room and up-to-date and
                  complete copies of the following documents are comprised in
                  the Data Room:

                  o        the deeds, documents and announcements (to extent not
                           already reflected in the trust deed) currently
                           governing the UPF which contain particulars of
                           benefits and entitlements and a copy of the latest
                           trustee report and accounts and actuarial valuation;
                           and

                  o        a full list of Relevant Employees as at the 1st July,
                           2001.

         (C)      The UPF is an "exempt approved scheme" (within the meaning of
                  Chapter I of Part XIV of The Income and Corporation Taxes Act
                  1988) and has at all times complied with and been administered
                  in all material respects in accordance with all applicable
                  laws, regulations and requirements, including the requirements
                  of the Inland Revenue for continued approval as an exempt
                  approved scheme or of the National Insurance Contributions
                  Office on behalf of the Inland Revenue for continued
                  eligibility for contracting-out of the UK state scheme and of
                  trust law. So far as the Vendor is aware, there is no reason
                  why approval of the UPF by the Board of Inland Revenue should
                  be withdrawn.

                                      160


         (D)      The UK Company holds or is named in an appropriate
                  contracting-out certificate as defined in the Pension Schemes
                  Act 1993.

         (E)      Contributions to the UPF payable by the UK Company are not
                  paid in arrears and all contributions to, and expenses of, the
                  UPF which have fallen due for payment by the UK Company have
                  been paid.

         (F)      There is no established practice in relation to the exercise
                  of discretion under the UPF to provide benefits to or in
                  respect of the Relevant Employees other than in accordance
                  with the Relevant Employees' or their dependants' entitlements
                  under the UPF. For the avoidance of doubt, the Purchaser is
                  required, subject to the terms of paragraph 4(B) and 5(B), to
                  maintain established practices as to the exercise of
                  discretions in relation to benefits notwithstanding any breach
                  of this warranty (F) and that obligation shall be taken into
                  account for the purpose of assessing damages for any breach of
                  this warranty (F).

         (G)      There is no dispute with regard to the benefits payable under
                  the UPF to or in respect of any UK Employee which is material
                  in the context of the total liabilities in respect of the
                  pre-Completion pensionable service of the UK Employees and no
                  legal proceedings by or against the trustees of the UPF in
                  their capacity as such in respect of such benefits are
                  pending, threatened or expected and so far as the Vendor is
                  aware there is no fact or circumstance likely to give rise to
                  such proceedings.

2.       BENEFITS TO BE PROVIDED BY THE PURCHASER

                           (b)      for the period of 3 years on and after the

                           transfer of such Benefits, or in the case of the
                           Unicare Savings Plan in the United States, to which
                           an individual can elect to rollover benefits from the
                           relevant Vendor's Non-UK Pension Plan and the
                           Purchaser will, or will procure that, each Relevant
                           Non-UK Employee is offered the opportunity to

                  (iii)    Any transfer payment from a funded Vendor's Non-UK
                           Pension Plan to any such plan established or
                           nominated by the Purchaser shall be calculated by
                           Vendor's Non-UK Actuary in accordance with applicable
                           law and local practice in relation to the Plan in
                           question.

                  (iv)     Where there is an established practice as to the
                           exercise of discretions in relation to Benefits, the
                           Purchaser shall continue that practice in relation to
                           the Benefits at (A)(i)(a) and (b) above. In relation
                           to each of the practices as to the exercise of
                           discretions referred to in ANNEX C to this PART B,
                           the Purchaser shall make an announcement to the
                           Relevant Non-UK Employees which is in form and
                           substance to the reasonable satisfaction of the
                           Vendor that it will continue that practice in
                           relation to the Benefits at (A)(i)(a) and (b) above.
                           However the Purchaser shall have the same rights of
                           variation and discontinuance of that practice as the
                           relevant member of the Vendor's Group has at the date
                           of this Agreement.

                  (v)      The obligations under (i) to (iv) above shall
                           continue in force even if the Purchaser disposes of a
                           member of the Purchaser's Group or all or any part of
                           the business thereof and accordingly the Purchaser
                           shall procure that the buyer concerned honours such
                           obligations in respect of each Relevant Non-UK
                           Employee concerned in such a disposal.

         (B)      The Purchaser shall procure that, in the satisfaction of its
                  obligation under PARAGRAPH 2(A), compulsory contributions
                  shall not be payable by a Relevant Non-UK Employee, except to
                  the extent otherwise expressly agreed in writing by that
                  Relevant Non-UK Employee, at a rate greater than the rate (if
                  any) at which:

                  (i)      he pays compulsory contributions at the Completion
                           Date, for a period of 1 year from the Completion Date
                           or, if shorter, the period expiring on the date on
                           which he is required to contribute to the Vendor's
                           Non-UK Pension Plan of which he was a member
                           immediately prior to the Completion Date under the
                           provisions of that plan, if he is then an active
                           member of that plan, or on which he would have been
                           required to contribute to the relevant Vendor's
                           Non-UK Pension Plan under the provisions of that
                           plan, had he then been an active member of that plan;
                           and

                  (ii)     he could have been required to contribute to the
                           Vendor's Non-UK Pension Plan in question under the
                           provisions of that Plan in force immediately prior to
                           the Completion Date but for any surplus or deficit in
                           that Plan, for the remainder of the period referred
                           to in PARAGRAPH 2(A)(i)(b) after the expiry of the
                           period in (I) above.

         (C)      For the purpose of (A) above:

                  (i)      "EQUIVALENT" means with an equivalent or greater
                           value and will be determined, in the case of defined
                           benefit Benefits, using the following actuarial
                           valuation method and assumptions:

                                      165


                           (a)      the same as those used in the most recent
                                    actuarial valuation of the plan published on
                                    or before the date of this Agreement to
                                    which the Benefits relate and, in the case
                                    of a funded plan, also used for actually
                                    funding those benefits, modified to such
                                    extent as may be agreed in writing by the
                                    Vendor's Non-UK Actuary and the Purchaser's
                                    Non-UK Actuary and the procedure referred to
                                    in PARAGRAPH 3 shall apply if any such
                                    modification is not so agreed, and

                           (b)      if there is no such actuarial valuation,
                                    such reasonable actuarial method and
                                    assumptions as may be agreed between the
                                    Vendor and the Purchaser or, in default of
                                    agreement, as determined under PARAGRAPH 3

                  provided that:

                  o        in the case of any Relevant Non-UK Employee with
                           Benefits under the UVO in Germany, equivalent
                           Benefits under the relevant Purchaser's Group Plan
                           will be identical to those under the UVO;

                  o        in the case of any Relevant Non-UK Employee with
                           Benefits under the Vendor's Non-UK Pension Plan in
                           France which provides a lump sum benefit (the "FRENCH
                           LUMP-SUM PLAN"), equivalent Benefits under the
                           relevant Purchaser's Group Plan will be identical to
                           those under the French Lump Sum Plan;

                  o        this PARAGRAPH 2(C)(i) does not apply in relation to
                           the Netherlands (see PARAGRAPH 2(D));

                  o        this PARAGRAPH 2(C)(i) does not apply in relation to
                           the US (see PARAGRAPH 2(F)).

         (ii)     equivalent Benefits in respect of service prior to Completion
                  Date must, in addition to satisfying (C)(i) above, also be of
                  a type or form approved by the Vendor.

         (iii)    It is agreed that defined contribution or money purchase
                  benefits ("DC BENEFITS") in place of Benefits which are of a
                  defined benefit type will not normally be considered
                  "equivalent" except where the equivalent Benefits are in
                  respect of Employees in the Netherlands, France or the US.

         (iv)     For the purpose of this paragraph 2, where the Purchaser is
                  permitted to provide Benefits on a DC Benefit basis,
                  "equivalent" shall relate to Benefits exclusive of
                  administration costs and the Vendor and the Purchaser agree to
                  operate the provisions of this paragraph 2 in accordance with
                  that principle.

(D)      (i)      This paragraph 2(D) applies in respect of any Relevant Non-UK
                  Employee with Benefits under the Progress Pension Fund in the
                  Netherlands.

         (ii)     In relation to each month of service on and after the
                  Completion Date, the employer contribution paid in respect of
                  each such Employee concerned for equivalent DC Benefits must
                  not be less than the aggregate of:

                  o        the Unilever Dutch Accounting Cost for the Employee
                           in question in relation to the Progress Pension Fund;
                           and

                  o        in relation to the period referred to in paragraph
                           2(B)(i), (A-B), where:

                           A        represents the amount of monthly
                                    contribution he could have been required to
                                    contribute to the Progress Pension Fund in
                                    question under the provisions of that Plan
                                    in force immediately prior to the Completion
                                    Date but for any surplus or deficit in that
                                    Plan; and

                           B        represents the amount (if any) of monthly
                                    compulsory contribution he pays to the
                                    Progress Pension Fund at the Completion
                                    Date;

                  For this purpose, "UNILEVER DUTCH ACCOUNTING COST" means the
                  employer cost, expressed as a percentage of pensionable pay
                  (over the period referred to below), less any allowance
                  included for administration costs, calculated in accordance
                  with the latest actuarial method and assumptions in relation
                  to the Progress Pension Fund used for Vendor's Group
                  accounting purposes prior to the Completion Date, in respect
                  of the period of 12 months immediately prior to the Completion
                  Date divided by 12 on the assumption that the Progress Pension
                  Fund is neither in surplus nor in deficit or calculated on
                  such other basis as the Vendor and the Purchaser shall agree,
                  provided that the provisions of paragraph 3 shall apply in the
                  event that there is no such agreement.

         (iii)    In relation to service prior to the Completion Date, the
                  Vendor and the Purchaser shall use their respective reasonable
                  endeavors to agree a treatment of the Benefits in respect of
                  each such Employee that provides compensation for the loss of
                  continuous service under the Progress Pension Fund which shall
                  be delivered through a combination of:

                  o       the deferred benefits of the Employee under the
                          Progress Pension Fund (where these remain to be
                          provided under the Progress Pension Fund) together
                          with any improvement made to them or, at the option of
                          the Employee concerned, the transfer of his benefits
                          under the Progress Pension Fund to the relevant
                          Purchaser's Group Plan; and

                  o       a lump sum addition to the opening balance credited to
                          the Employee's DC Benefit account in the relevant
                          Purchaser's Group Plan and/or extra employer
                          contributions spread over a future period;

                  with the objective that the aggregate value as at the
                  Completion Date of all such elements, to the extent
                  applicable, in respect of each such Employee,

                                      167


                  calculated on the basis of the actuarial method and
                  assumptions in relation to the Progress Pension Fund used for
                  Vendor's Group accounting purposes prior to the Completion
                  Date, should be equivalent to the value as at Closing of that
                  Employee's benefits under the Progress Pension Fund on the
                  basis of that actuarial method and assumptions.

         (iv)     (a)      To the extent so agreed, the Vendor's Non-UK Actuary
                           shall determine the value in local currency as at the
                           Completion Date of:

                           o        the part of such aggregate value referred to
                                    at (iii) above as at the Completion Date
                                    provided under the Purchaser's Group Plan,
                                    using the actuarial method and assumptions
                                    used in the latest actuarial valuation of
                                    the Progress Pension Fund used for Vendor's
                                    Group accounting purposes before the date of
                                    this Agreement; less

                           o        the assets transferred from the Progress
                                    Pension Fund to the Purchaser's Group Plan,
                                    adjusted in respect of the period from the
                                    date of transfer to the Completion Date
                                    using a basis consistent with that adopted
                                    by the Progress Pension Fund for adjusting
                                    the value of assets transferred from the
                                    Completion Date to the date of transfer,

                          and shall provide such calculation and the amount of
                          any resulting shortfall to the Purchaser's Non-UK
                          Actuary.

                  (b)      Paragraph 9 of Part A of this Schedule shall apply
                           mutatis mutandis.

                  (c)     Within 10 Business Days after the value referred to in
                          (a) has been agreed or determined, the Vendor shall
                          pay to the Purchaser, so far as possible by way of
                          repayment of the Cash Consideration payable in respect
                          of the Shares of Unipath B.V., an amount in pounds
                          sterling (converted from Euros at the closing
                          mid-point exchange rates appearing in The Financial
                          Times on the last Business Day prior to the date of
                          payment) equal to:

                           o        any shortfall referred to at (a) above
                                    multiplied by (1.0 less X), where X
                                    represents the standard maximum corporate
                                    tax rate for the Netherlands as at the
                                    Completion Date (expressed as a percentage
                                    rate divided by 100);

                           o        adjusted by the discount rate used in the
                                    actuarial assumptions referred to in (a)
                                    above in respect of the period from the
                                    Completion Date to the day before the date

                  be an active member of the Vendor's Non-UK Pension Plan in
                  question for so long as he remains employed by a member of the
                  Purchaser's Group or any buyer referred to in PARAGRAPH
                  2(A)(v) (whether or not continuing to accrue benefits under
                  the Purchaser's Group Plan in question).

         (H)      The mechanics of achieving (A) above will be determined by the
                  applicable laws of the jurisdiction in question and the legal
                  provisions conferring and governing the Benefits.

         (I)      Where any transfer of Benefits or assets in respect of those
                  Benefits requires the approval or consent of any regulatory
                  body or any third party (including the Relevant Non-UK
                  Employees), the Vendor and the Purchaser shall use their
                  respective reasonable endeavours to obtain such approvals and
                  consents.

         (J)      The Purchaser shall procure that admission of a Relevant
                  Non-UK Employee to the applicable Purchaser's Group Plan is
                  not conditional on his consenting to the transfer of his
                  Benefits in any Vendor's Non-UK Pension Plan in respect of his
                  past service.

         (K)      Where Benefits are provided under a Vendor's Non-UK Pension
                  Plan on the death or disability of a Relevant Non-UK Employee
                  or his spouse, child or dependant, equivalent Benefits must be
                  provided on such events which are payable in circumstances and
                  under conditions which are not materially less favourable to
                  the beneficiary concerned as those which would have applied
                  had the death or disability occurred whilst the beneficiary
                  was a beneficiary of the Vendor's Non-UK Pension Plan in
                  question under the provisions of that Plan in force
                  immediately prior to the Completion Date. For the purpose of
                  this PARAGRAPH 2(K), the benefit payable under the applicable
                  Purchaser's Group Plan in the US may be reduced by the amount
                  of any benefit payable on the same event in respect of the
                  individual concerned by the relevant Vendor's Non-UK Pension
                  Plan in the US.

         (L)      Any announcement to be issued by the Vendor or a member of the
                  Purchaser's Group in relation to Benefits the subject of this
                  PARAGRAPH 2 must be consistent with the terms of this
                  PARAGRAPH 2 and, prior to the issue of any such announcement,
                  the Vendor or, as the case may be, the Purchaser, shall
                  provide to the other a copy of the intended announcement and
                  shall not issue it without prior consultation with the other.

         (M)      The Purchaser's agreement to the provisions of this PARAGRAPH
                  2 is given by the Purchaser on the express understanding that,
                  if the Purchaser is in breach of any of such provisions, the
                  Vendor may, at its absolute discretion, and without
                  limitation, seek to procure compliance with such provisions by
                  the Purchaser by applying to the court for damages and/or
                  specific performance.

         (N)      The Vendor shall use all reasonable endeavours to permit
                  Unipath Diagnostics GmbH to participate in the Berolina
                  Pensionskasse, in relation to those Relevant Non-UK Employees
                  who participate in the Berolina Pensionskasse immediately
                  prior to the Completion Date, for a temporary period after the
                  Completion Date not to exceed one year, subject to the
                  obtaining of appropriate consents and approvals and on the
                  basis that no employer or employee contributions are payable
                  in respect of that period.

         (O)      (i)      In this paragraph 2(O), references to the "CHICOGO
                           INACTIVES" are references to those former employees
                           of Unipath Diagnostics GmbH who have Benefits under
                           the UVO immediately prior to the Completion Date
                           ("UVO BENEFITS").

                  (ii)     The Vendor shall use all reasonable endeavours to
                           procure that the consent of the Chicogo Inactives is
                           obtained, prior to the expiry of the period of one
                           year after the Completion Date, to the transfer of
                           the obligation to provide UVO Benefits in respect of
                           them to a member of the Vendor's Group.

                  (iii)    The following provisions of this paragraph 2(N) apply
                           in respect of those Chicogo Inactives (if any) whose
                           consent referred to in (ii) above is not obtained
                           within the period referred to at (ii) above
                           ("NON-CONSENTING CHICOGO INACTIVES").

                  (iv)     As soon as reasonably practical after the expiry of
                           the period of one year after the Completion Date, the
                           Vendor's Non-UK Actuary shall determine the value in
                           Euros as at the Completion Date of the UVO Benefits
                           applicable in respect of the Non-Consenting Chicogo
                           Inactives in accordance with the actuarial method and
                           assumptions set out in Annex B to this Part B,
                           together with an appropriate adjustment to reflect
                           the value as at the Completion Date of any payments
                           made under (vii) below, and shall provide such
                           calculation to the Purchaser's Non-UK Actuary.

                  (v)      Paragraph 9 of Part A of this Schedule shall apply
                           mutatis mutandis.

                  (vi)     Within 10 Business Days after the value referred to
                           in (iv) has been agreed or determined, the Vendor
                           shall pay to the Purchaser, so far as possible by way
                           of repayment of the Cash Consideration payable in
                           respect of the Shares of Unipath Diagnostics GmbH, an
                           amount in pounds sterling (converted from Euros at
                           the closing mid-point exchange rates appearing in The
                           Financial Times on the last Business Day prior to the
                           date of payment)equal to (A + B) adjusted by C,
                           where:

                           A        represents the part of that value which has
                                    been recognised for tax purposes;

                                      173


                           B        represents the part of that value which has
                                    not been recognised for tax purposes,
                                    multiplied by (1.0 less X), where X
                                    represents the standard maximum corporate
                                    tax rate for Germany as at the Completion
                                    Date (expressed as a percentage rate divided
                                    by 100); and

                           C        represents the discount rate referred to in
                                    Annex B to this Part B in respect of the

                                    before the date of payment.

                  (vii)    The Vendor shall, at its cost, administer and procure
                           the payment of any payment falling due to any Chicogo
                           Inactive during the period from the Completion Date
                           to the expiry of the period of one year after the
                           Completion Date. The Purchaser shall provide all
                           reasonable assistance to the Vendor in connection
                           with such payments, including the provision of any
                           relevant data or information in the possession or
                           control of the Purchaser.

3.       DISPUTES

         (A)      Any dispute between the Vendor and the Purchaser or between
                  the Vendor's Non-UK Actuary and the Purchaser's Non-UK Actuary
                  concerning the determination or valuation or agreement of any
                  matter to be specifically determined, valued or agreed under
                  this PART B of this Schedule shall, in the absence of
                  agreement between them, be referred to an independent actuary
                  agreed by the Vendor and the Purchaser or, failing such
                  agreement, appointed by the President for the time being of
                  the Institute of Actuaries in England at the request of the
                  party first applying.

         (B)      Such independent actuary shall act as an expert and not as an
                  arbitrator. His decision shall be final and binding on the
                  parties and his expenses shall be borne between the Vendor of
                  the one part and the Purchaser of the other part as the
                  independent actuary may direct.

4.       EXPATRIATE EMPLOYEES

         The general principles to be applied in relation to those Employees who
         are employed in the Transferring Business as at the Completion Date in
         a country which is not their home country ("EXPATRIATES") are that:

         (A)      the Purchaser shall provide or procure the provision of
                  Benefits to Expatriates in accordance with the terms promised
                  to those Expatriates by the relevant member of the Vendor's
                  Group or any Company; and

         (B)      the Vendor and the Purchaser shall, in relation to each such
                  Expatriate, agree the most appropriate and cost effective way
                  for those Benefits to be provided having regard to applicable
                  laws and tax regimes.

5.       PENSION WARRANTIES

         (A)      Save in respect of:

                                      174


                  o        the Vendor's Non-UK Pension Plans;

                  o        the relevant state scheme or any industry-wide
                           scheme;

                  o        any arrangement the sole purpose of which is to
                           provide benefits on injury or death; and

                  o        any arrangement which only provides death benefits
                           secured by an insurance policy,

                  no member of the Vendor's Group, nor any Non-UK Company (the
                  "EMPLOYER")

                  (i)      has any obligation to:

                           o        pay any pension;

                           o        make any other payment on or after
                                    retirement or death; or

                           o        otherwise to provide Benefits

                           to, or in respect of, any Relevant Non-UK Employee or
                           spouse or dependant of such Relevant Non-UK Employee;
                           and

                  (ii)     is a party to or obligated to contribute to any
                           scheme or arrangement having as its purpose, or one
                           of its purposes, the making of any such payments or
                           the provision of any such benefits to, or in respect
                           of, any Relevant Non-UK Employee or spouse or
                           dependant of such Relevant Non-UK Employee.

         (B)      Up-to-date and complete copies of the governing documentation
                  (including explanatory booklets and announcements to members
                  to the extent applicable) of each Vendor's Non-UK Pension Plan
                  (other then the ITP in Sweden) are comprised in the Data Room.

         (C)      Each Vendor's Non-UK Pension Plan has at all times complied
                  with applicable law and its governing documentation in all
                  material respects.

         (D)      There is no dispute with regard to the Benefits of the
                  Relevant Non-UK Employees in any country which is material in
                  the context of the total liabilities in respect of the
                  pre-Completion pensionable service of such Relevant Non-UK
                  Employees and no legal proceedings by or against the Employer
                  in respect of such Benefits is pending, threatened or
                  expected, and so far as the Vendor are aware there is no fact
                  or circumstance likely to give rise to such proceedings.

         (A)      Subject to the provisions of sub-clauses (D) and (E) below,
                  the Purchaser shall, with effect from Completion, procure the
                  grant to the Vendor of a non-exclusive, perpetual, worldwide,
                  assignable, irrevocable, royalty-free licence (with the right
                  to sub-license) in respect of any Company IPR (excluding all
                  trade marks) and know-how owned by any of the Companies which
                  has been used (but not exclusively used) in the twelve months
                  prior to Completion by a member of the Vendor's Group or the

                  animal IN VITRO diagnostics, save that the Vendor shall have
                  no right to grant sub-licences in respect of any patents or
                  patent applications included within Company IPR except to
                  members of the Vendor's Group or for the purpose of having
                  products manufactured, researched and/or developed for it by
                  third parties.

         (B)      Subject to the provisions of sub-clauses (F) and (G) below,
                  the Vendor shall, with effect from Completion, grant or
                  procure the grant to the Purchaser of a non-exclusive,
                  perpetual, worldwide, assignable, irrevocable, royalty-free
                  licence (with the right to sub-license) in respect of the
                  Shared IPR to use, manufacture, research, develop and/or sell
                  products in the Defined Field and in the fields of human and
                  animal IN VITRO and IN VIVO diagnostics only (save to the
                  extent that the Shared IPR is licensed pursuant to the
                  Antibody Patent Licence, in which case the terms of the
                  Antibody Patent Licence shall apply), save that the Purchaser
                  shall have no right to grant sub-licences in respect of any
                  patents or patent applications included within Shared IPR
                  except to members of the Purchaser's Group or for the purpose
                  of having products manufactured, researched and/or developed
                  for it by third parties.

         (C)      Neither party shall disclose (other than to permitted
                  sub-licensees under obligations of confidentiality no less
                  onerous than this SUB-CLAUSE (C)) any know-how licensed to
                  such party pursuant to SUB-CLAUSE (A) or, as the case may be,
                  (B) to any third party except under an obligation of
                  confidence, provided that this obligation shall not apply to
                  know-how:

                  (i)      which was already available to the public before the
                           date of this Agreement;

                  (ii)     which subsequently becomes available to the public
                           through no fault of the receiving party;

                  (iii)    which is lawfully disclosed to the receiving party by
                           a third party without obligation of confidence; or

                  (iv)     which the receiving party can prove was developed by
                           that party wholly independently of the information
                           received from the donor.

         (D)      The Vendor shall identify and provide the Purchaser with a
                  list of all patents and patent applications ("PATENTS"),
                  within eighteen months from the date of this

                                      184


                  Agreement in respect of patent applications filed within (i)
                  six months prior to the date of this Agreement, or (ii) three
                  months after the date of this Agreement, and within twelve
                  months from the date of this Agreement in respect of all other
                  Patents (the "IDENTIFICATION PERIOD"), which are Company IPR
                  and which the Vendor claims are included within the licence
                  granted pursuant to SUB-CLAUSE (A), together with a brief
                  description of the use of such Patents by the member of the
                  Vendor's Group other than in connection with the Transferring
                  Business. At the Vendor's reasonable request, the Purchaser
                  shall provide reasonable assistance to the Vendor in
                  connection with such identification of Patents. If the
                  Purchaser disputes whether any Patent is included within that
                  licence, the Parties agree to submit such dispute to a
                  mutually acceptable, independent third party arbitrator for
                  final binding arbitration and the Party whose assertion is not
                  upheld in relation to any Patent shall pay all the arbitration
                  costs (including the other Party's costs) in relation to the
                  dispute in respect of that Patent.

         (E)      After the Identification Period, the licence granted to the
                  Vendor pursuant to SUB-CLAUSE (A) shall terminate insofar only
                  as it relates to Patents except for any Patent which has been
                  identified by the Vendor pursuant to Clause (D) and which the
                  Vendor has agreed is included within that licence or which an
                  arbitrator pursuant to SUB-CLAUSE (D) has determined is
                  included within that licence or which has been submitted for
                  resolution in accordance with SUB-CLAUSE (H).

         (F)      The Purchaser shall, within the Identification Period,
                  identify and provide the Vendor with a list of all Patents
                  owned by a member of the Vendor Group which the Purchaser
                  claims are included within the definition of Shared IPR
                  together with a brief description of the use of such Patents
                  by the Company or in the US Business. At the Purchaser's
                  reasonable request, the Vendor shall provide reasonable
                  assistance to the Purchaser in connection with such
                  identification of Patents. If the Vendor disputes whether any
                  Patent is included within the definition of Shared IPR the
                  Parties agree to submit such dispute to a mutually acceptable,
                  independent third party arbitrator for final binding
                  arbitration and the Party whose assertion is not upheld in
                  relation to any Patent shall pay all the arbitration costs
                  (including the other Party's costs) in relation to the dispute
                  in respect of that Patent.

         (G)      After the Identification Period, the licence granted to the
                  Purchaser to use Shared IPR pursuant to SUB-CLAUSE (B) shall
                  terminate insofar only as it relates to Patents except for any
                  Patent which has been identified by the Purchaser pursuant to
                  SUB-CLAUSE (F) and which the Vendor has agreed is included
                  within Shared IPR or which an arbitrator pursuant to
                  SUB-CLAUSE (F) has determined is included within Shared IPR or
                  which has been submitted for resolution in accordance with
                  SUB-CLAUSE (H).

         (H)      If a dispute or difference arises in connection with this
                  Schedule, the parties shall attempt to resolve such dispute or
                  difference through the following procedure:

                  (i)      at the written request of either party, the
                           resolution of a dispute or difference shall be
                           escalated for good faith consideration, and where
                           possible, resolution by a senior patent attorney of
                           the Licensors' Group and the Chief Scientific Officer
                           of the Licensee; and

                  (ii)     failing agreement by the persons in SUB-CLAUSE (H)(i)
                           above within 30 days of such written request such
                           dispute or difference may be referred at the written
                           request of either party to the Head of Patents of the
                           Licensors' Group and the

                           Chief Executive Officer of the Licensee's Group. If
                           the dispute or difference is not resolved within 30
                           days of such request, either party may initiate
                           proceedings in accordance with SUB-CLAUSE 1(D) or
                           1(F) as appropriate,

         provided that nothing in this sub-clause (H) shall prevent or restrict
         either party's right to seek injunctive relief for any actual or
         suspected unauthorised use or other unlawful act in respect of its
         rights (and/or the rights of any member of its Group) in Intellectual
         Property or know-how.

 2.      VITAMIN LICENCE AND ASSISTANCE

         (A)      The Vendor hereby grants the Purchaser and the Purchaser's
                  Group a non-exclusive, royalty-free, perpetual, irrevocable,
                  worldwide, assignable licence (including rights to grant
                  sub-licences) to use in the Defined Field and in the field of
                  human and animal IN VITRO and IN VIVO diagnostics (i) any
                  Intellectual Property or know-how owned by a member of the

                  research on electrochemical detectors for the assessment of
                  vitamins in food products and in blood carried out (a) at the
                  Vendor's Colworth laboratory by Robert Porter and/or (b) which
                  is the subject of the IP assignment dated 18th December, 2001
                  between Unipath Limited and Unilever UK Central Resources
                  Limited as disclosed to the Purchaser (the "Research
                  Project"), and (ii) any patent or patent application whether
                  existing now or after the date of this Agreement, to the
                  extent covering (a) any such know-how owned by a member of the

                  pursuant to this paragraph (A), save that the Purchaser shall
                  have no right to grant sub-licences in respect of any patents
                  or patent applications included within such licence except to
