ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

     On September 23, 1997, Waters Corporation, along with its wholly owned
subsidiary, Waters Technologies Corporation, (collectively referred to herein as
the "Company"), completed its acquisition of Micromass Limited and its
subsidiaries (collectively referred to herein as "Micromass"), a British
company. Pursuant to the transaction, the Company purchased 100% of the capital
stock of Micromass from Micromass management, Micromass Employee Share Scheme
Limited, and certain funds of Schroder Ventures for aggregate consideration of
(Pounds) 109.0 million ($175.9 million) consisting of cash, stock and notes./1/
The Acquisition was financed through drawings on the revolving credit facility
under the Company's Amended and Restated Credit Agreement, dated as of June 16,
1997, as amended by the First Amendment dated September 4, 1997, by and among
the Company, Bankers' Trust Company and other Lenders party thereto (the "Credit
Agreement").

     Micromass is a manufacturer of mass spectrometers and will operate as a
wholly owned subsidiary of Waters Technologies Corporation, the Company's wholly
owned operating company, with headquarters in Manchester, England.

     PROPERTIES

     As a consequence of this acquisition, the Company has obtained various
intellectual property rights as well as the following leaseholds used by
Micromass for manufacturing and office space purposes. In addition to the
properties listed below, Micromass maintains small sales offices in various
European locations.  The Company believes that these facilities, together with
planned expenditures for normal maintenance, capacity and technological
improvements will provide adequate production capacity to meet current demand
for Micromass products.  The Company currently has no plans to alter the
existing usage of these properties.
 
                                                                    APPROX.

                    Unrestricted Stock and Restricted Stock notified to the
                    Buyer in writing at today's date;

             2.2.2  the payment of (Pounds)46,392,380 in the aggregate for the
                    416,667 "B" Ordinary shares of 1p each, the 520,833 "B"
                    Redeemable shares of 1p each and the 6,188,110 Preference
                    shares of 1p each

                                      -6-

             For the avoidance of doubt nothing in this clause 2.2 shall,
             subject to clause 4.6, oblige the Buyer to pay more than
             (Pounds)94,358,020 or issue more than the aggregate amount of
             Unrestricted Stock, Restricted Stock and Loan Notes notified by the
             Sellers pursuant to this clause 2.2.

             Furthermore in the event the Shares sold pursuant to this Agreement
             fail to include any shares of the Company or any other securities
             convertible or exchangeable into Shares, it is the express
             understanding among the Buyer and the Sellers that the Sellers
             shall adjust the consideration per share among all of the Shares
             and the Sellers agree that the Buyer shall have no liability to any
             other holders of Shares.

        2.3  The Buyer shall not be obliged to complete the purchase of any of
             the Shares unless the Sellers complete the sale of all of the
             Shares simultaneously, and if the Buyer, in its sole discretion,
             elects to purchase some of the Shares if not all of the Shares are
             tendered then the completion of the purchase of some of the Shares
             shall not affect the rights of the Buyer with respect to its rights
             to the other Shares.

        2.4  Each of the Sellers whose names are set out in Part III of schedule
             1 separately confirms that its obligations under this Agreement
             constitute valid and binding obligations on it in accordance with
             the terms of this Agreement.

        2.5  The Managers acknowledge that they will following Completion have
             no further right, title or interest in the shares currently held by
             Micromass Employee Share Scheme Limited.

        2.6  The Buyer undertakes to keep the notifications pursuant to clause
             2.2 confidential unless required to disclose them by law or
             regulation of the Securities Exchange Commission.

3.    CONDITIONS

             material adverse change);

      3.1.4  all conditions set out in the commitment letter from Bankers' Trust
             to the Buyer, in the agreed form, being satisfied or waived and the
             funds to be made available to the Buyer pursuant to that letter
             becoming available to the Buyer;

      3.1.5  there being no matter arising after the date of this Agreement
             which would give rise to a Relevant Claim in respect of which,
             having regard to the limitations set out in schedule 5, any of the
             Managers would be liable if the Warranties and the Additional
             Warranties were to be repeated immediately before Completion;

      3.1.6  there having been no material breach of the provisions of clauses
             5.8 and 17.

      the case of clauses 3.1.5 and 3.1.6 the Managers shall not be obliged to
      incur any personal cost or liability.

3.4   If at any time any of the Sellers or the Buyer becomes aware of a fact or
      circumstances that might prevent a condition set out in clause 3.1 being
      satisfied it shall immediately inform the other party.

                                      -8-
<PAGE>
 
3.5   If a condition set out in clause 3.1 has not been satisfied and in the
      case of conditions set out in clauses 3.1.3 to 3.1.6 has not been waived
      by the Buyer by 2.30pm (London Time) on 23 September 1997, the Buyer will
      on that date, by written notice to the Sellers;

      3.5.1  waive the condition; or

      3.5.2  terminate this Agreement.

3.6   If the Buyer terminates this Agreement pursuant to clause 3.5.2 each
      party's further rights and obligations cease immediately on termination
      (provided that clauses 9 and 11 shall both survive), but termination does
      not affect a party's accrued rights and obligations at the date of
      termination.

4.    COMPLETION

4.1   Subject to clause 3, Completion shall take place at the office of the
      Sellers' Solicitors at 2.30pm (London Time) on 23 September 1997.
 
4.2   At Completion each of the Sellers shall deliver to the Buyer each item

4.3   The Sellers shall ensure that at, on or prior to Completion the Company's
      directors hold a meeting of the board of directors of the Company at which
      the directors:

      4.3.1  vote in favour of the registration of the Buyer or its nominee(s)

                                      -9-
<PAGE>
 
      4.3.6  approve and authorise the Company's execution of the Employment
             Contracts.
 
4.4   The Sellers shall ensure that, immediately after the board meeting
      referred to in clause 4.3:

      4.4.1  any meeting of the board of directors of a Subsidiary Undertaking
             that the Buyer may require is held; and

      4.4.2  any meeting held pursuant to clause 4.4.1 deals with any matter
             referred to in clause 4.3 that the Buyer may require.

4.5   At Completion:

      4.5.1  Technologies shall pay 74.9% of the cash stated in clause 2.2 to
             the Sellers' Solicitors' account with Midland Bank plc, Poultry &
             Princess Street EC2P 2BX:

             Sort Code: 40-05-30
             Account Name Clifford Chance: Client Account
             Account Number:  2318 1499;

      4.5.2  Technologies shall issue the Loan Notes to which each Seller is
             entitled;

      4.5.3  Waters shall allot and issue the amounts of Unrestricted Stock and
             Restricted Stock notified pursuant to clause 2.2, subject always to
             clause 4.6;

      4.5.4  Waters shall pay 25.1% of the cash stated in clause 2.2 to the
             account specified in clause 4.5.1.

      The Sellers irrevocably authorise the Sellers' Solicitors to receive the
      cash referred to in clause 4.5.1 on behalf of the Sellers and payment to
      them will be good discharge to the Buyer which will not be further
      concerned as to the application of the moneys so paid.

4.6   If the average closing price of Common Stock of $0.01 of the Buyer as
      announced on the composite transactions page of The Wall Street Journal
      for the period (if any) ending 2 trading days before the Completion Date
      and starting today's date (the "AVERAGE PRICE") is greater or less than
      the average of the closing of Waters Stock on 9th, 10th and 11th September
      1997 (the "Base Price") then the amount of Unrestricted and Restricted
      Stock to be issued by Waters as consideration hereunder shall be adjusted
      using the following formula:-

                                      -10-
<PAGE>
 
      Revised number        =    Number of relevant amount of Stock set out in

      of the relevant Stock      Schedule 1 x the Base Price and then divided by
                                 the Average Price

      Provided always that the number of Unrestricted and Restricted Stock
      calculated as set out above will never be less than 90% or more than 110%
      of the relevant number of Stock set out in schedule 1.

      No fractional Unrestricted or Restricted  Stock shall be issued to any
      Seller, but in lieu thereof cash shall be paid to the relevant Seller.

      For the purposes of this clause 4.6 "trading day" shall mean a day upon
      which shares can be traded on The New York Stock Exchange.

4.7   In the event of Completion occurring on any date other than 30 September
      1997 the date of Completion shall be 30 September for the purposes of the
      financial statements to be prepared as at 30 September 1997.

4.8   If prior to Completion Regulation S of the Securities Act of 1933 is
      amended so that Unrestricted Stock can not be freely transferred in the
      United States of America following 40 days of its issue then the Managers
      who would otherwise be having Unrestricted Stock issued to them shall
      instead be entitled at their election to receive cash in respect of their
      shares, calculated on the same basis as they would have received cash if
      they had so elected at today's date.
 
5.    WARRANTIES

5.1   The Managers jointly and severally warrant to the Buyer that each Warranty
      and Additional Warranty is true and accurate.  Without prejudice to the
      meaning of the foregoing sentence in the case of the Second Group Managers
      each of the Warranties shall be deemed to be given only insofar as that
      individual is aware of the facts and matters which are the subject of that
      Warranty.  Each of the Warranties are separate and independent
      representations and the Buyer shall have a separate claim and right of
      action in respect of every breach provided always that the Buyer shall not
      be entitled to recover twice for loss arising from the same breach.

5.2   Subject to clause 5.3, if a Warranty is untrue or inaccurate whether or
      not that Warranty also constitutes a misrepresentation which the Buyer
      relied on in entering this Agreement:

      5.2.1  the Buyer's only remedy in respect of the Warranty is in damages
             for breach of clause 5.1 (which may include reasonable legal fees
             if so awarded by a competent Court);

      5.2.2  the Sellers (including, for the avoidance of doubt, the Managers)
             are not liable (in equity or tort, under the Misrepresentation Act
             1967 or in any other way) in respect of the misrepresentation save
             in damages for breach of clause 5.1; and

      5.2.3  except as set out in clause 3.5, the Buyer may not terminate or
             rescind this Agreement as a result of breach of the Warranty or the
             misrepresentation.

                                      -11-
<PAGE>
 
5.3   Clause 5.2 does not affect the Sellers' liability or the Buyer's rights or
      remedies in respect of a fraudulent misrepresentation.

5.4   The Warranties are qualified by reference to any matter or thing which is
      fairly disclosed in this Agreement, or is fairly disclosed in the
      Disclosure Letter or in any of the documents annexed to the Disclosure
      Letter.

5.5   Each Warranty is to be construed independently and (except where this
      Agreement provides otherwise) is not limited by a provision of this
      Agreement or another Warranty.

5.6   Save for any claims in respect of any breach of the warranties or any
      delay in the discovery of such breach, arising as a result of fraud,
      schedule 5 operates to limit or exclude, as the case may be, the Managers'
      liability for Relevant Claims.  Provided always that the limitation
      contained in paragraph 3 of schedule 5 shall continue to apply in respect
      of all Managers except those guilty of such fraud.

5.7   The Managers waive any right which they may have in respect of a
      misrepresentation, inaccuracy or omission in or from information or advice
      supplied or given by a Group Company or a director, officer or employee of
      a Group Company for the purpose of assisting the Managers to make a
      representation, give a Warranty or prepare the Disclosure Letter and the
      Managers undertake to the Buyer not to bring any claim to enforce any such
      right.

5.8   Between the execution of this Agreement and Completion the Managers shall
      ensure that each Group Company shall (unless the Buyer otherwise
      consents):

      5.8.1  not create, allot, issue, acquire, repay or redeem any share or
             loan capital or agree, arrange or undertake to do any of those
             things or acquire or agree to acquire, an interest in a corporate
             body, association or partnership;

      5.8.2  operate its business only in the ordinary course of business
             (consistent with past custom and practice in the previous year) and
             so as to maintain that business as a going concern;

      5.8.3  not acquire or dispose of, or agree to acquire or dispose of, an
             asset except in the usual course of its business (consistent with
             past custom and practice since 30 March 1996) or assume or incur,
             or agree to assume or incur, a liability, obligation or expense
             (actual or contingent) except in the usual course of its business;

      5.8.4  not declare, pay or make a dividend or distribution or make any
             other payment to any Seller or person connected with a Seller save
             for a payment by way of remuneration or repayment of expenses in
             the ordinary course of business;

      5.8.5  not pass a shareholders' resolution;

      5.8.6  not create, or agree to create, an Encumbrance over the Property or
             another asset or redeem, or agree to redeem, an existing
             Encumbrance over the Property or another asset;

                                      -12-
<PAGE>
 
      5.8.7  not amend the terms of employment or engagement (except in the
             usual course of business) of a Manager or provide or agree to
             provide a gratuitous payment or benefit to a Manager (or any of
             their dependants);

      5.8.8  not start litigation or arbitration proceedings save that this
             shall not apply in relation to the litigation matters disclosed in
             the Disclosure Letter;

      5.8.9  not compromise, settle, release, discharge or compound litigation
             or arbitration proceedings or a liability, claim, action, demand or
             dispute, or waive a right in relation to litigation or arbitration
             proceedings save that this shall not apply in relation to the
             litigation matters disclosed in the Disclosure Letter;

      5.8.10 conduct its business in all material respects in accordance with
             all applicable legal and administrative requirements in any
             jurisdiction;

      5.8.11 not enter into an agreement, arrangement or obligation (legally
             enforceable or not) in which the Sellers or a person connected with
             any of them is interested; and

      5.8.12 not authorise or agree to take any of the foregoing action.

      Provided that nothing in this clause 5.8 shall prevent the issue of C
      Redeemable Shares in the Company or the execution of the Employment
      Contracts.

5.9   The Warranties and the Additional Warranties shall be deemed to be
      repeated immediately before Completion as if made at such time.  Between
      execution of this Agreement and Completion the Managers shall notify the
      Buyer if any of them becomes aware of a fact or circumstance which would
      constitute a breach of clause 5.1.  Provided that for the avoidance of
      doubt this clause shall only give the Buyer the right to terminate this
      Agreement for the non-fulfilment of the condition in clause 3.1.5 and it
      shall not give the right to bring an action in damages against the
      Managers unless they knowingly breach the obligation to notify set out in
      this clause.

6.    FURTHER UNDERTAKINGS BY THE MANAGERS

6.1   For a period ending on the earlier, in the case of each Manager, of the
      date upon which that Manager ceases to be employed by the Company (save as
      a result of the Manager voluntarily resigning) and the third anniversary
      of Completion, in the case of any First Group Manager, or the second
      anniversary of Completion, in the case of any Second Group Manager, the
      Managers separately undertake not to directly or indirectly:

      6.1.1  operate, or be engaged, concerned or interested in, or assist, a
             business which competes, directly or indirectly, with a business of
             a Group Company as operated at the date of this Agreement in a
             territory in which the business is operated at that date, whether
             alone or jointly with, through or as manager, adviser, consultant
             or agent for another person; or

      6.1.2  solicit the custom of any customer of a Group Company in the 12
             months prior to Completion with respect to goods competitive with
             those manufactured by any Group Company immediately prior to
             Completion; or

                                      -13-
<PAGE>
 
      6.1.3  solicit or endeavour to entice any person who during the period of
             twelve months prior to Completion was an employee of any Group
             Company likely (in the reasonable opinion of the Buyer) to be in
             possession of confidential information relating to, or able to
             influence the customer connection of the Group, to leave the
             service or employment of any Group Company; or

      6.1.4  do or say anything which is harmful to a Group Company's reputation
             or which may lead a person to cease to deal with a Group Company on
             substantially equivalent terms to those previously offered or at
             all; or

6.2   The Managers separately undertake not to directly or indirectly disclose,
      use or fail to maintain the confidentiality of any non-public information
      belonging to any Group Company immediately prior to Completion save as
      would otherwise be permitted pursuant to clause 9.2.

6.3   Each restriction in clauses 6.1 and 6.2 constitutes an entirely
      independent restriction on each of the Managers.

6.4   Each undertaking contained in this clause 6 is and shall be construed as
      separate and severable and if one or more of the undertakings is held to
      be against the public interest or unlawful or in any way an unreasonable
      restraint of trade or unenforceable in whole or in part for any reason,
      the remaining undertakings, or parts thereof (as appropriate), shall
      continue to bind the Managers.

6.5   If any undertaking contained in this clause 6 is found to be void but
      would be valid if the period of application were reduced or if some part
      of the undertaking were deleted, the undertaking in question shall apply
      with such modification as may be necessary to make it valid and effective.

7.    EMPLOYMENT CONTRACTS

7.1   It is acknowledged by each of the Managers that as part of the sale and
      purchase of the Shares each Manager will be required (without any further
      payment) to enter into an Employment Contract which includes a provision
      that the Group Company which employs him can upon his employment ceasing
      require him not to take alternative employment for one year after such
      termination provided that the relevant Group Company pays him (in addition
      to any other statutory amount to which he may be entitled on termination)
      an amount equal to the amount of his net remuneration (including, on a pro
      rata basis, the annual performance related bonus to which he would be
      entitled) received for the year prior to the date of such termination.

7.2   The Buyer undertakes to each Manager that during the period of 3 years
      from Completion it will cause the relevant Group Companies to maintain a
      compensation structure for the Managers a significant portion of which
      shall be based on the performance of the business and which shall result
      in target pay in each calendar year not less than the 1997 target pay set

9.1   Subject to clause 9.2, no party may, before or after Completion, make or

      the written consent of the Buyer, Robert Williams and Carl Parker, which
      may not be unreasonably withheld or delayed.

9.2   Clause 9.1 does not apply to a public announcement, communication or
      circular:

      9.2.1  required by law or a regulation of a stock exchange (including for
             the avoidance of doubt the filing of accounts in respect of the
             Group with the Securities and Exchange Commission), if the party
             required to make or send it has, if practicable, first consulted
             and taken into account the reasonable requirements of the other
             party; or

      9.2.2  made or sent by the Buyer after Completion to a customer, client,
             supplier or employee of any Group Company informing it of the
             Buyer's purchase of the Shares; or

      9.2.3  which is in an agreed form at today's date.


10.   COMPETITION

      If there are provisions of this Agreement (or of an agreement or
      arrangement of which it forms part) by virtue of which particulars of this
      Agreement (or of an agreement or arrangement of which it forms part) are,
      at the date of this Agreement, required to be furnished to the Director
      General of Fair Trading under the Restrictive Trade Practices Acts 1976
      and 1977 those provisions do not take effect until the day after those
      particulars have been furnished.

11.   COSTS

      Except where this Agreement provides otherwise, the Sellers on the one
      hand and the Buyer on the other hand shall pay their own respective costs

                                      -15-
<PAGE>
 
12.2  The failure to exercise or delay in exercising a right or remedy provided
      by this Agreement or by law does not constitute a waiver of the right or
      remedy or a waiver of other rights or remedies.  No single or partial
      exercise of a right or remedy provided by this Agreement or by law
      prevents further exercise of the right or remedy or the exercise of
      another right or remedy.

      supersedes any previous agreements between the parties relating to the

      under the Misrepresentation Act 1967 or in any other way) for a
      representation that is not set out in this Agreement.

13.4  Clause 13 does not affect the Sellers' liability in respect of a
      fraudulent misrepresentation.

14.   ASSIGNMENT

      A party may not assign or transfer or purport to assign or transfer any of
      its rights or obligations under this Agreement, provided that on or prior
      to Completion, the Buyer may either assign all of its rights under this
      Agreement to any Buyer's Group Undertaking or the Buyer may assign the
      benefit of this Agreement to its lenders as collateral security provided
      always that the Buyer shall remain liable to perform its obligations
      hereunder notwithstanding any such assignment.

15.   NOTICES

15.1  A notice or other communication under or in connection with this Agreement
      shall be in writing and shall be delivered personally or sent by first

16.   GOVERNING LAW AND JURISDICTION

16.1  This Agreement is governed by English law.

16.2  The courts of England have exclusive jurisdiction to hear and decide any
      suit, action or proceedings, and to settle any disputes, which may arise
      out of or in connection with this

                                      -16-
<PAGE>
 
      Agreement (respectively, "PROCEEDINGS" and "DISPUTES") and, for these
      purposes, each party irrevocably submits to the jurisdiction of the courts
      of England.

16.3  All parties irrevocably waive any objection which they might at any time
      have to the courts of England being nominated as the forum to hear and
      decide any Proceedings and to settle any Disputes and agree not to claim
      that the courts of England are not a convenient or appropriate forum.

16.4  Process by which any Proceedings are begun in England may be served on the
      Sellers by being delivered either in accordance with clause 15 or, in the
      case of the Buyer, to the Managing Director at Floats Road, Wythenshawe,
      Manchester, M23 9LE with a copy to the Chief Financial Officer at the
      Buyer who is irrevocably authorised to accept service on behalf of the
      Buyer.  Nothing contained in clause 16.4 affects the right to serve
      process in another manner permitted by law.

17.   EXCLUSIVITY

      The Sellers agree not, prior to the Completion Date, directly or
      indirectly through any connected person or adviser to enter into any
      discussion, negotiation, agreement or arrangement with any person except
      the Buyer or its subsidiaries, their employees and advisers with respect
      to a sale of a Group Company (whether by way of sale of shares or the sale
      of substantially all of the assets of a Group Company or by merger, tender
      offer or otherwise).

18.   SPECIFIC PERFORMANCE

      The Managers acknowledge that damages would not be an adequate remedy for
      a breach of this Agreement and that the Buyer is entitled to the remedies
      of injunction, specific performance and other equitable relief for any
      threatened or actual breach.

19.   ACCESS

      The Managers shall allow the Buyer and its employees reasonable access to
      the Property and to the Managers provided that nothing in this clause
      shall oblige the Managers to reveal trade secrets or information of a
      confidential nature.  The Buyer agrees to keep all confidential
      information so received confidential and to comply with the terms of a
      confidentiality undertaking entered into with Micromass Limited in respect
      of such information.

20.   FURTHER ASSISTANCE

20.1  The Managers will use their reasonable endeavours to procure the release,
      at Completion, of securities held by Bank of Scotland plc and Barclays
      Bank plc over the Group Companies' assets and provide details which would
      be sufficient to enable the redemption of debt and all forward exchange
      and swap contracts at the option of the Buyer, provided that nothing shall
      oblige any of them to pay any sum of money or incur any personal liability
      to obtain such release.

20.2  It is acknowledged by the Managers and the Buyer that financial statements
      in respect of the Group have to be filed with the Securities and Exchange
      Commission in respect of the 9 months ending 30 September 1997 within 75
      days of Completion.

21.   COUNTERPARTS

      This Agreement may be executed in any number of counterparts each of which
      when executed and delivered is an original, but all the counterparts
      together constitute the same document.

22.   EFFECT OF COMPLETION

      The terms of this Agreement (insofar as not performed at Completion and
      subject as specifically otherwise provided in this Agreement) shall
      continue in force after and notwithstanding Completion.  In particular,
      without limitation, the remedies of the Buyer in respect of any breach of
      clause 5.1 shall continue to subsist notwithstanding Completion.

      equivalent taxation authority).

4.8   SECONDARY LIABILITY
      No transaction act omission or event has occurred (including without
      limitation the execution or implementation of this Agreement) in
      consequence of which any of the Group Companies is or may be held liable
      for any Taxation, or may otherwise be held liable for or to indemnify any
      person in respect of any Taxation which is primarily or directly
      chargeable against or attributable to any person other than any of the
      Group Companies.  No transaction act omission or event has occurred which
      has resulted or could result in any charge lien security interest
      incumbrance or other third party right arising over any of the Group
      Companies' assets in respect of unpaid Tax.

4.9   RESIDENCE

4.9.1 Save as disclosed in the Disclosure Letter, each of the Group Companies
      is, and will at Completion, be resident for taxation purposes in the
      jurisdiction in which such company was incorporated and for the purposes
      of Schedule 7 Finance Act 1988 none of the Group Companies have ceased to
      reside in the United Kingdom for United Kingdom Taxation purposes pursuant
      to a Treasury consent other than a general consent.

4.9.2 None of the Group Companies carries on, and none of the Group Companies
      has carried on, any trading activities through a branch or agency or other
      permanent establishment, any other business in any jurisdiction other than
      that in which it was incorporated.

4.10  TRANSFER PRICING
      All transactions entered into by any of the Group Companies (or branch or
      permanent establishment of such person in another jurisdiction) with a
      person resident in another

                                      -59-

        jurisdiction have been entered into on an arm's length basis and the
        consideration (if any) charged or received or paid by any of the Group
        Companies on all transactions entered into by it with a person resident
        in another jurisdiction has been equal to the consideration which might
        have been expected to be charged, received or paid (as appropriate)
        between independent persons dealing at arm's length.

4.11    DISTRIBUTIONS

4.11.1  The Company has not made in the last 6 years a distribution except for
        dividends shown in the Accounts.

                                  SCHEDULE  5
                     LIMITATIONS ON THE MANAGERS' LIABILITY

1.    No Manager is liable in respect of a Relevant Claim unless the amount that
      would otherwise be recoverable from the Managers (disregarding this
      paragraph 1) in respect of that Relevant Claim exceeds (Pounds)150,000 in
      which case subject to their limitations in this schedule the Managers
      shall be liable for the whole amount.

2.    No Manager is liable in respect of a Relevant Claim unless and until the
      amount that would otherwise be recoverable from the Managers (but for this
      paragraph 2) in respect of that Relevant Claim, when aggregated with any
      other amount or amounts recoverable in respect of other Relevant Claims
      (excluding any amounts in respect of a Relevant Claim for which the
      Managers have no liability because of paragraph 1), exceeds
      (Pounds)3,000,000 in which case subject to their limitations in this
      schedule the Managers shall be liable for the whole amount.

3.    The aggregate total liability of each Manager in respect of all Relevant
      claims shall not exceed the amount set out against his name in schedule 1.

4.    A Manager is not liable in respect of a Relevant Claim unless the Buyer
      has given the Managers' Representatives notice of the Relevant Claim
      (stating in reasonable detail the nature of the Relevant Claim and, if
      practicable, the amount claimed) within 18 months of Completion, save in
      respect of a Relevant Claim in respect of any Additional Warranty not
      being true and accurate where a Manager shall not be liable unless the
      Buyer commences proceedings in respect of such claim before Completion.

5.    A Relevant Claim notified in accordance with paragraph 4 and not
      satisfied, settled or withdrawn is unenforceable against a Manager on the
      expiry of the period of nine months starting on the day of notification of
      the Relevant Claim, unless proceedings in respect of the Relevant Claim
      have been issued and served on the Manager in accordance with clause 15.

6.    A Manager is not liable in respect of a Relevant Claim:

                                      -61-
<PAGE>
 
      6.1   to the extent that the matter giving rise to the Relevant Claim
            would not have arisen but for:

            6.1.1 an event, act, transaction or omission after Completion at the
                  request or direction of, or with the acquiescence or consent
                  of a Buyer's Group Undertaking or a director, employee or
                  agent of a Buyer's Group Undertaking;

            6.1.2 the passing of, or a change in, after the date of this
                  Agreement a law, rule, regulation, interpretation of the law
                  or administrative practice of a government, governmental
                  department, agency or regulatory body or an increase in the
                  Tax rates or an imposition of Tax, in each case not actually
                  or prospectively in force at the date of this Agreement;

      6.2   to the extent that the matter giving rise to the Relevant Claim
            arises wholly or partially from an event, act, transaction or
            omission on or before the date the Managers acquired the shares in
            the Company and none of Managers were  aware of the matter giving
            rise to the Relevant Claim;

      6.3   to the extent that the amount of  the Relevant Claim is an amount
            for which a Group Company has actually recovered an amount from, a
            person other than another Group Company, whether under a provision
            of applicable law, insurance policy or otherwise howsoever;

      6.4   if a Buyer's Group Undertaking fails to act in accordance with
            paragraph 9 in connection with the matter giving rise to the
            Relevant Claim, to the extent the Managers are actually prejudiced
            by such failure;

      6.5   to the extent that the matter giving rise to the Relevant Claim was
            taken into account in computing the amount of an allowance,
            provision or reserve in the Accounts.

7.    The Buyer undertakes to take all such action as it reasonably could to
      enforce any right of recovery it has against or an indemnity from, a
      person other than another Group Company, whether under a provision of
      applicable law, insurance policy or otherwise.

                                      -62-
<PAGE>
 
8.    The Buyer is not entitled to recover from any one Manager more than once
      in respect of any one matter giving rise to a Relevant Claim.

9.    If the Buyer becomes aware of a matter which might give rise to a Relevant
      Claim:

      9.1  the Buyer shall promptly give notice to the Managers' Representatives
            of the matter and shall consult with the Managers, Representatives
            with respect to the matter;

      9.2   the Buyer shall, and shall ensure that each Buyer's Group
            Undertaking will at the request of the Managers, provide to the
            Managers and their advisers reasonable access to premises and
            personnel and to relevant assets, documents and records within each
            Buyer's Group Undertaking's power or control (save for information
            created or arising after Completion which is the subject of legal
            professional privilege) for the sole purposes of investigating the
            matter and enabling the Managers to take the action referred to in
            paragraph 9.4.1;

      9.3   the Managers (at their cost) may upon request to the Buyer take
            copies of the documents or records, and photograph the premises or
            assets, referred to in paragraph 9.2;
 
      9.4   the Buyer shall and shall ensure that each Buyer's Group Undertaking
            will (at the cost of the Managers):

            9.4.1 at the request of the Managers, take any action and institute
                  any proceedings, and give any information and assistance, as
                  the Managers may reasonably request in order to:

                  (a)      dispute, resist, appeal, compromise, defend, remedy
                           or mitigate the matter; or

                  (b)      enforce against a person (other than a Group Company)
                           a Buyer's Group Undertaking's rights in relation to
                           the matter; and

                                      -63-
<PAGE>
 
            9.4.2  in connection with proceedings related to the matter (other
                  than against a  Group Company) use advisers nominated by the
                  Managers' Representatives and, if the Managers request, allow
                  the Managers the exclusive conduct of the proceedings all at
                  the cost of the Managers,

            and in each case on the basis that the Managers shall fully
            indemnify each Buyer's Group Undertaking for all reasonable costs
            incurred as a result of a request or nomination by the Managers;

      9.5   the Buyer shall not, and shall ensure that no Buyer's Group
            Undertaking will, admit liability in respect of, or compromise or
            settle, the matter without the prior written consent of the
            Managers' Representatives (not to be unreasonably withheld or
            delayed).

      9.6  the Managers agree not to use any information which they are given by
            a Group Company pursuant to paragraph 9.4.

10.   For the purposes of this schedule 5 the Buyer shall be entitled to assume
      and the Managers confirm that the Managers' Representative shall have the
      necessary authority to act on behalf of all the Managers where this
      schedule 5 permits any action to be taken by the Managers'
      Representatives.

11.   In assessing any damages or other amounts recoverable for a Relevant Claim
      there shall be taken into account any corresponding savings by, or net
      benefit to, a Buyer's Group Undertaking which it actually receives.

11.1  If the Managers pay to a Buyer's Group Undertaking an amount in respect of
      a Relevant Claim and a Buyer's Group Undertaking subsequently recovers
      from another person an amount which relates to the some loss or damage
      with respect to the Relevant Claim:

      11.1.1  if the amount paid by the Managers in respect of the Relevant
              Claim is more than the Sum Recovered, the Buyer shall immediately
              pay to the Managers the Sum Recovered by paying to each Manager a
              proportion of the Sum Recovered which bears the same proportion to
              the Sum Recovered as the amount paid by that

                                      -64-
<PAGE>
 
              Manager in respect of the Relevant Claim bears to the total amount
              paid by the Managers in respect of the Relevant Claim; and

      11.1.2  if the amount paid by the Managers in respect of the Relevant
              Claim is less than or equal to the Sum Recovered, the Buyer shall
              immediately pay to each Manager an amount equal to the amount paid
              by that Manager in respect of the Relevant Claim.

11.2  For the purposes of paragraph 11.1 "SUM RECOVERED" means an amount equal
      to the total of the amount recovered from the other person plus in the
      case of a repayment from the UK Inland Revenue any repayment supplement in
      respect of the amount recovered from the person under section 825 of the
      Taxes Act 1988 plus any interest in respect of the amount recovered from
      the person less all reasonable costs incurred by a Buyer's Group
      Undertaking in recovering the amount from the person and any tax
      liability.

12.   Nothing in schedule 5 restricts or limits the general obligation of the
      Buyer's Group Undertaking at law to mitigate any loss or damage which it
      may incur in consequence of a matter giving rise to a Relevant Claim.

13.   If at any time after the date of this Agreement a Manager wants to insure
      against liabilities in respect of Relevant Claims, the Buyer shall provide
      any information as a prospective insurer may reasonably require before
      effecting the insurance.

14.   The Buyer shall, and shall ensure that each Group Company will, preserve
      all documents, records, correspondence, accounts and other information
      whatsoever relevant to a matter which may give rise to a Relevant Claim
      for the longer of the period of 18 months following Completion or the
      period in which a Relevant Claim remains outstanding.

15.   Any payment made by a Manager in respect of a Relevant Claim shall be
      treated by that Manager and the Buyer as a reduction in the purchase price
      of the Shares to the extent of the payment.

16.   The provisions of schedule 5 do not apply to a Relevant Claim if it is
      based on a fraudulent misrepresentation by a Manager.
