       the Vendors' joint and several liability under clause 5.1.

5.6    SEPARATE AND INDEPENDENT WARRANTIES AND FUNDAMENTAL REPRESENTATIONS

         nevertheless that the amount so repaid shall not exceed the amount
         previously paid to Bluestone and/or Europe by the Vendors in respect
         of such breach.

5.10.9   Any Claim shall (if it has not previously been settled or withdrawn)
         be deemed to have been withdrawn on the date which is twelve months
         after it has been notified unless prior to that date a notice of
         reference to arbitration or notice of the issue of court proceedings
         shall have been served upon the Vendors.

5.10.10  The Vendors shall not be liable to Bluestone and/or Europe under the
         Warranties, the Knowledge Warranty, the Fundamental Representations
         or under the Taxation Undertaking to the extent that the Claim
         arises or is increased as the result of the passing of any
         legislation (or the making of any subordinate legislation) with
         retrospective effect which is announced after the Completion Date.

5.10.11  If any claim is made against the Group or Bluestone and/or Europe by
         a third party in respect of which the Vendors shall be liable to
         Bluestone and/or Europe for a breach of any of the Warranties, the
         Knowledge Warranty or the Fundamental Representations Bluestone
         and/or Europe shall:-

         (a)  not knowingly make any admission of liability, agreement or
              compromise with any person, body or authority in relation
              thereto without the prior consent of the Vendors (such consent
              not to be unreasonably withheld or delayed); and

         (b)  give the Vendors and their professional advisers reasonable
              confidential access to any documents and records of the Group
              to enable the Vendors and their professional advisors to
              examine such documents and records and to take copies thereof
              at their own expense; and

         (c)  take such action as the Vendors shall reasonably require to
              avoid dispute, resist appeal, compromise or defend the matter
              which gives rise to any claim provided that the Vendor shall
              have secured Bluestone and/or Europe to its reasonable
              satisfaction and fully indemnified it as to all liabilities,
              costs, damages and expenses which it may reasonably incur by
              reason of such action.

         If the Vendors shall not request Bluestone and/or Europe to take any
         such action, or shall fail to indemnify and secure the liabilities,
         costs, damages and expenses as aforesaid within 14 days after
         written notice shall have been given to the Vendors then Bluestone
         and/or Europe shall be free to pay or settle the claim on such terms
         as it shall, in its absolute discretion, think fit.

5.10.12  In the event that Bluestone and/or Europe is entitled to claim under
         more than one of the Warranties, the Knowledge Warranty, Fundamental
         Representations or under the Taxation Undertaking in respect of the
         same subject matter, Bluestone and/or Europe may choose to claim
         under more than one of the Warranties, the Knowledge Warranty,
         Fundamental Representations or under the Taxation Undertaking but
         shall not be entitled to recover more than once in respect of the
         same loss.

5.10.13  Bluestone shall not, following Completion, be entitled to treat the
         Vendors as having repudiated this Agreement or be entitled to
         rescind this Agreement.

5.11     SATISFACTION OF CLAIMS


5.11.1   Bluestone and Europe shall be entitled, without prejudice to any
         other rights or remedies available to them, to satisfy the amount of

         Bluestone and/or Europe would have a reasonable prospect of making a
         valid claim under the Fundamental Representations, the Warranties,
         the Knowledge Warranty or the Taxation Undertaking until such claims
         become Determined Claims or the Vendors cease to have liability in
         respect of such claims pursuant to the terms of this Agreement or
         the Taxation Undertaking.

5.11.3   In the event Bluestone intends to withhold payment of the Escrow

             provide within 40 Business Days his opinion as to whether
             Bluestone and/or Europe has a reasonable prospect of making a
             valid claim under the Fundamental Representations, the
             Warranties, the Knowledge Warranty or the Taxation Undertaking;

         (b) Counsel shall be entitled to consult with the Vendors'
             Solicitors and Bluestone's Solicitors and/or any other party
             which he deems appropriate for the purposes of giving his
             opinion;

         (c) in giving his opinion, Counsel shall act as expert and not
             arbitrator and any costs or expenses incurred in connection with
             the obtaining of Counsel's opinion shall be borne by:

             (i)  in the event the matter of the opinion becomes a Determined
                  Claim, the Vendors; or


             (ii) otherwise, by Bluestone or as Counsel may otherwise direct;
                  and


         (d) each of the Vendors and Bluestone hereby agree and undertake to
             provide or procure as provided, access to all books, records,
             accounts, information and personnel as Counsel may deem
             necessary for the purposes of giving his opinion.

         Solicitors and the Vendors' Solicitors; such amount to be released:

         (a)  to the extent the matter the subject of Counsel's opinion does not
              become a Determined Claim within 2 years of the date hereof, to
              the Vendors; and

         (b)  to the extent the matter the subject of Counsel's opinion becomes
              a Determined Claim within 2 years of the date hereof, to Bluestone
              in which event the Vendors hereby waive any entitlement they may
              have to receive the relevant part of the Deferred Consideration.


         Interest on any amounts held in such joint account shall follow, and
         be released, with the principal monies to which such interest
         relates.

5.12     ESCROW STOCK


         The Vendors agree that Bluestone shall be entitled to retain the

         available to it, be authorised and entitled to dispose of or cancel

         that no Claim shall have been made on or before the first
         anniversary of Completion, Bluestone undertakes to deliver to the

         extent of such Claim, shall be

         or be answerable for the loss or misapplication of such sum) the
         balance of the Escrow Cash. In the event that any Claims are made

         5.13 shall be paid together with a further sum calculated as the
         amount (less any withholding taxes or other lawfully required
         deductions) which could have been earned on such payment if it had
         been held on deposit for the period commencing on the Completion
         Date and terminating on the date of payment (both dates exclusive)
         on an account attracting interest at a rate equivalent to the rate

         but if any Determined Claim shall remain outstanding for a period in

         of the Determined Claim outstanding.

13       SEVERANCE

         enforceable provision which achieves to the greatest extent possible
         the same effect as would have been achieved by the illegal, invalid
         or unenforceable provision. The obligations of the parties under any
         invalid or unenforceable provision of this Agreement shall be
         suspended while an attempt at such substitution is made.
