     Sellers shall have notified the Buyer of any disagreement or difference of
     opinion relating to the Completion Accounts, and if, using their respective

     Accountant and shall endeavour to procure that the matters required of each
     of them under this clause 5 are fulfilled as soon as practicable after
     their respective appointments. Without prejudice to the generality of the

          Completion Accounts have been accepted or settled (whether under
          clause 5.3, 5.4 or 5.5) together with interest on the amount to be
          paid calculated at the rate of 2 per cent. above the base lending rate

          date for payment) or to the bank account of the Sellers' Solicitors
          (if payment is to be made by the Buyer). Payment of such sum by such
          method shall be an effective discharge of the

     of the Sale Shares and for that purpose each Seller authorises:

     5.10.1 the Company to send any notices or other communications in respect
          of his holding of Sale Shares to the Buyer; and

     5.10.2 the Buyer to complete in such manner as it thinks fit and to return
          proxy forms, consents to short notice and any other document required
          to be signed by him in his capacity as a member.

     with or breach of any provision of this agreement, it can still enforce
     that right, obligation or provision or claim that remedy subsequently and
     that waiver shall not be deemed to be a waiver of any subsequent breach of
     that or any other provision or of any other right, obligation or remedy.

11.5 The discontinuance, abandonment or adverse determination of any proceedings
     taken by either party to enforce any right or any provision of this

     enforcement or (as the case may be) further or other exercise or
     enforcement by such party of, that or any other right or provision.

11.6 All references in clauses 11.2 to 11.5 to:

     to any rights under this agreement enforceable under the Contracts Act by

11.9 All of the provisions of this agreement shall, so far as they are capable
     of being performed or observed, continue to be effective notwithstanding

     remain liable in full in respect of that Relevant Breach (but without
     prejudice to their right to a contribution).

          by any of the methods specified in that clause, on the second (or,
          when sent by airmail, fifth) business day after the day of posting or
          (in the case of a notice transmitted by facsimile transmission) on
          receipt by the sender of a transmission report showing the successful
          transmission of the whole of the relevant notice or (if that
          transmission is not made during normal working hours on a business
          day) at 9.00 a.m. on the next business day.

14.1 The Agreed Documents constitute the entire agreement between the parties in
     relation to the sale and purchase of the Sale Shares and other matters
     covered by them and supersede any previous agreement between the parties in
     relation to those matters, which shall cease to have any further effect. It
     is agreed that:


                                       21
<PAGE>
     14.1.1 no party has entered into any Agreed Document in reliance on, and
          each party unconditionally waives any claims in relation to, any
          statement, representation, warranty or undertaking that is not
          expressly set out or referred to in the Agreed Documents;

     14.1.2 in the absence of fraud, no party shall have any remedy in respect
          of any untrue statement made, to it or its representatives or agents,
          prior to this agreement being entered into and on which it or they
          relied other than representations, warranties or undertakings set out
          or referred to in the Agreed Documents and that party's only remedy in
          respect of representations, warranties and undertakings set out in the
          Agreed Documents shall be for breach of contract; and

     14.1.3 this clause shall not exclude any remedy or liability for fraudulent
          concealment or fraudulent misrepresentation.

14.2 Each Seller confirms that there are no agreements to which both he (or any
     connected person) and the Company are party, other than those of the Agreed
     Documents (if any) to which they are parties.

15.  ALTERATIONS

15.1 No purported alteration of this agreement shall be effective unless it is
     in writing, refers specifically to this agreement and is duly executed by
     each party to this agreement.

16.  SEVERABILITY

16.1 Each provision of this agreement is severable and distinct from the others.
     The parties intend that each of those provisions shall be and remain valid
     and enforceable to the fullest extent permitted by law. If any such
     provision is or at any time becomes to any extent invalid, illegal or
     unenforceable under any enactment or rule of law, it shall to that extent
     be deemed not to form part of this agreement but (except to that extent in
     the case of that provision) it and all other provisions of this agreement
     shall continue to be effective and their validity, legality and
     enforceability shall not be affected or impaired as a result, subject to
     the operation of this clause not negating the commercial intent and purpose
     of the parties under this agreement. The proviso to clause 1.2.6 shall be
     read subject to this clause 16.1.

16.2 If any provision of this agreement is illegal or unenforceable because any
     period or area specified in it exceeds that permitted by a Relevant
     Authority, that provision shall take effect with the minimum modification
     necessary to make it valid, effective and acceptable to that Relevant
     Authority subject to that modification not negating the commercial intent
     of the parties under this agreement.

17.  COUNTERPARTS

17.1 This agreement may be entered into in the form of two or more counterparts
     each executed by one or more of the parties but, taken together, executed
     by all of them and, provided that each party duly executes such a
     counterpart, each of the executed counterparts, when duly exchanged or
     delivered, shall be deemed to be an original, but, taken together, they
     shall constitute one instrument.

18.  PAYMENT OF COSTS

18.1 Each party shall be responsible for that party's own legal and other costs
     incurred in relation to the negotiation, preparation and completion of each
     of the Agreed Documents and all other relevant documents.

     expenses in connection with any investigation relating to the Company or
     with the negotiation, completion or implementation of the Agreed Documents.

     of this agreement.

     19.4.2 no person (including any employee, officer, agent, representative or
          sub-contractor of a party) other than a party to this agreement shall
          have the right (whether under the Contracts Act or otherwise) to
          enforce any term of this agreement which expressly or by implication
          confers a benefit on that person without the express prior agreement
          in writing of the parties, which agreement must refer to this clause
          19.4.

19.5 No consent shall be required from any person having rights under this
     agreement by virtue only of the Contracts Act to any amendment, variation,
     waiver or settlement of this agreement or any right or claim arising from
     or under it which (in each case) has been agreed by any party to it.
