      options over TCC common stock which have been approved under Schedule 9 to
      the Income and Corporation Taxes Act 1988 ("ICTA"), by the United Kingdom
      Board of Inland Revenue ("Approved Options").

11.2  The parties agree that:

      11.2.1 if the amendments required to the TCC Plan referred to in CLAUSE
             11.1 require the approval of the holders of TCC common stock then
             TCC shall not be obliged to seek such approval of such stockholders
             and CLAUSE 11.1 shall not apply; and

             make and in effecting any amendment of the TCC Plan pursuant to
             CLAUSE 11.1 shall be borne by the

      SCHEDULE 10 of such number of options over TCC common stock as are set
      against their respective names in COLUMN 2 of PART B of SCHEDULE 10 of
      which the maximum number permissible under paragraph 28 of schedule 9 to
      ICTA shall be Approved Options.

11.5  If the TCC Plan shall not be amended pursuant to CLAUSE 11.1, whether
      because approval of TCC stockholders would be required or because the
      United Kingdom Inland Revenue refuses to grant approval of the amendments
      or otherwise, then TCC shall, as soon as reasonably practicable, grant to
      each of the persons listed in COLUMN 1 of PART B of SCHEDULE 10 such

      of TCC common stock on the New York Stock Exchange ("Market Price") on the
      last trading day prior to the execution and exchange of this Agreement or
      in the case of the Approved Options, an exercise price per share
      determined by reference to such other method of calculating the Market
      Value of TCC common stock at their date of grant as the Board of Inland
      Revenue may allow.

      TCC agrees that, following Completion, it shall grant options over TCC
      common stock, up to the maximum number of options set out in PART C of

11.7  The Purchaser agrees to grant, as soon as reasonably practicable following
      Completion, options over the Earn-Out Shares pursuant to the Scheme to
      such of the employees of the Group and in such numbers as the Vendor
      shall, at any time within the three month period following Completion,
      direct.

      that any Sellers who have given personal guarantees in respect of the
      Group Companies shall be released from such personal guarantees and,

4.         ACCOUNTS

4.1        General

           The Accounts:-

           4.1.1 were prepared in accordance with the requirements of all
                 relevant statutes, with good accounting principles and
                 practices generally accepted at the date hereof in the United
                 Kingdom (including the Accounting Standards) for companies
                 carrying on a similar business to that of the Group Companies
                 and on a basis consistent with preceding accounting periods of
                 the Group Company concerned and with the books of account of
                 the Group Company concerned and are true and accurate in all
                 material respects; and

           4.1.2 show a true and fair view of the assets and liabilities of the
                 relevant Group Company at the Balance Sheet Date and of its
                 profits for the financial year ended on such date.

4.2        Stock-in-trade and work-in-progress

           The basis of valuation for stock-in-trade and work-in-progress has
           remained in all material respects consistent with that adopted for
           the purpose of the Group's audited accounts of the Group Company
           concerned in respect of the beginning and end of each of the
           accounting periods of the Group Company for the last three financial
           years.

4.3        Profits

           The profits of the Group Companies for the three years ended on the
           Balance Sheet Date as shown by the Accounts and by the audited
           accounts of the Company for previous periods delivered to the
           Purchaser and the trend of profits shown by them have not (except as
           disclosed in them) been affected to a material extent by
           inconsistencies of accounting practices, by the inclusion of
           non-recurring items of income or expenditure, by transactions entered
           into otherwise than on normal commercial terms or so far as the
           Vendor is aware by any other factors rendering such profits for all
           or any of such periods exceptionally high or low.

                 accordance with applicable standards, principles and practices
                 generally accepted in the United Kingdom and on a basis
                 consistent with the Accounts; and

           4.4.2 without prejudice to the generality of the foregoing, do not
                 reflect the turnover and the cost of sales of the Group for the
                 period they cover in a materially inaccurate way.

5.1        Since the Balance Sheet Date each Group Company:-

                 controlled, used or occupied by the Group and all the rights or
                 interests vested in the Group relating to any land and premises
                 at the date hereof and the particulars set out in SCHEDULE 3

                 Property is the subject of outstanding or threatened disputes,
                 claims or proceedings for cancellation, revocation, opposition,
                 interference, rectification or contested ownership.

                 business.

          18.2.4 No Group Company has taken any action likely to diminish the

          18.3.2 So far as the Vendor is aware, all Intellectual Property
                 Agreements are valid and binding and none has been the subject
                 of any breach or default by any party or of any event which
                 with notice or lapse of time or both would constitute a
                 default.

          18.3.3 So far as the Vendor is aware, there are no disputes, claims
                 or proceedings arising out of or relating to the Intellectual
                 Property Agreements.

          18.3.4 No Group Company has authorised or otherwise permitted,
                 expressly or by implication, any use whatsoever of the
                 Intellectual Property nor granted to any third party any right
                 or interest in respect of the Intellectual Property other than
                 under the Intellectual Property Agreements.

          18.3.5 All Intellectual Property Agreements have been duly recorded
                 or registered with the proper authorities whenever a
                 requirement to do so exists.

                                      -62-





18.4      Infringement

          18.4.1 No Group Company has infringed and nor do any infringe any
                 Intellectual Property of a third party as a result of any Group
                 Company's use or exploitation of the Intellectual Property
                 owned, used or exploited by any Group Company nor, so far as
                 the Vendor is aware, will such use or exploitation give rise to
                 any such dispute claims or proceedings against any Group
                 Company.

          18.4.2 There are not and have not been any disputes, claims or
                 proceedings threatened or in existence in any court or tribunal
                 in respect of any of the Intellectual Property as such owned,
                 used or exploited by any Group Company or in respect of any use
                 or exploitation of the Intellectual Property owned, used or
                 exploited by any Group Company.

          18.4.3 So far as the Vendor is aware, there has been and is no current
                 infringement by any third party of any of the Intellectual
                 Property owned, used or exploited by any Group Company.

18.5       Trade Marks

           All registered Trade Marks owned by any Group Company have been, and
           are being, used by the relevant Group Company in the course of its
           business in relation to the goods or services in respect of which
           they are registered and no Group Company has any reason to believe
           that any such Trade Mark may be struck off the register of trade
           marks as a result of non-use.

19.        LEGISLATION

           So far as the Vendor is aware, no Group Company is in breach of or
           has received notice of or is aware of any allegation of breach of the
           requirements of any legislation which is applicable to it.

                 Taxation Authority.

      20.1.9     Anti avoidance provisions

                 No Group Company has entered into or been a party to any scheme

                     liability of the Vendor under the Environmental Indemnity;


              3.3.5  wholly or partly as a result of a change of accounting
                     policy or practice of the Purchaser or any Group Company
                     introduced after the date of this Agreement;


       3.4    under the Warranties or the Indemnities to the extent that the
              Purchaser or any Group Company makes recovery under the terms of
              any insurance policy against any loss or damage it may suffer.

4.     For the avoidance of doubt, the liability of the Vendor under the
       Warranties or the Indemnities shall not be limited by any contingent
       liability noted in the Completion Accounts unless a specific provision or
       reserve is also included in such accounts in which event PARAGRAPH 3.2
       above shall apply.

5.     The Purchaser shall reimburse to the Vendor an amount equal to any sum
       paid by the Vendor in respect of any breach of any of the Warranties or
       pursuant to the Indemnities which is subsequently recovered by the
       Purchaser or any Group Company from any third party, after deducting from
       such sum its reasonable costs received in connection with such recovery
       and any Taxation thereon.


6.     If a claim is made by a third party against the Purchaser or any Group
       Company in respect of a matter in respect of which it appears that the
       Vendor is or may become liable under the Warranties, then the Purchaser
       shall as soon as reasonably practicable give notice thereof to the Vendor
       and, at the written request of the Vendor and subject to the Purchaser
       being indemnified and kept indemnified to its reasonable satisfaction
       against any claims, costs, expenses and other liabilities, the Purchaser
       shall take such action as the Vendor may reasonably require to avoid,
       dispute or compromise such claim and the Purchaser shall render to the
       Vendor all such assistance as the Vendor require in disputing such claim.
       Nothing in this PARAGRAPH 6 shall oblige the Purchaser to take any action
       where, in the opinion of the Purchaser, such action would cause damage to
       the goodwill of the Business of any part thereof. No claim by the
       Purchaser under the Warranties shall be prejudiced by:-


       6.1    any failure to give notice to the Vendor as aforesaid; or

       6.2    any decision by the Purchaser not to take any action requested by
              the Vendor in order to protect the goodwill of the Business or any
              part thereof.

7.     If any claim is made by the Purchaser for breach of any of the Warranties
       or the Indemnities then, for the purpose of determining the amounts for
       which the




                                      -83-




       Vendor is liable as a result of such breach, there shall be taken into
       account and credit given for the amount by which at the date of such a
       claim any liability of the Group Companies provided for in the Completion
       Accounts has been discharged or satisfied below the amount provided
       therefore in the Completion Accounts.

8.     The Tax Warranties shall not apply to Aspect Vision Italia s.r.l.

    PART 2 - FINANCIAL LIMITATIONS UNDER THE WARRANTIES, INDEMNITIES AND THE
                              DEED OF TAX COVENANT

9.     The liability of the Vendor in respect of any claim::-

       9.1    under the Warranties, the Indemnities or the Deed of Tax Covenant
              shall not arise unless and until the amount of such claim, when
              aggregated with the amount of any other such claim made against
              the Vendor under this Agreement or under the Deed of Tax Covenant
              (or which would have been made but for the operation of this
              PARAGRAPH 8) exceeds 'L'150,000 in which event all of such claim
              or claims shall be recoverable hereunder;

       9.2    under the Warranties, the Indemnities or the Deed of Tax Covenant
              shall not (when aggregated with the amount of all other claims
              made against the Vendor under the Warranties, the Indemnities or
              the Deed of Tax Covenant) exceed twenty per cent (20%) of the
              Total Consideration (the "Cap"). For the purposes of this
              PARAGRAPH 9.2, the Total Consideration shall be calculated at the
              time the liability for the claim is due to be satisfied and shall
              be the aggregate of:-

              9.2.1  the Cash Consideration;

              9.2.2  the nominal value of the Purchase Notes;

              9.2.3  the nominal value of the EOLN; and

              9.2.4  the aggregate consideration paid by the Purchaser for such
                     of the Earn Out Shares, or for the options over the
                     Earn-Out shares, as have been purchased by the Purchaser
                     pursuant to the Earn-Out Agreement at that date;

       SO THAT where a claim is to be satisfied before the EOLN has been issued
       and/or the Earn Out Shares have been purchased and as a result of the
       calculation of the Cap at that time the claim is not satisfied in full,
       the balance of the amount payable in respect of the claim shall not be
       extinguished but shall remain outstanding and shall be paid by the Vendor
       at the time the EOLN is issued and/or Earn Out Shares are purchased to
       the extent that the Cap, recalculated at that time, increases.

                 PART 3 - TIME LIMITATIONS UNDER THE WARRANTIES
            (OTHER THAN TAX WARRANTIES AND ENVIRONMENTAL WARRANTIES)



                                      -84-




10.    The liability of the Vendor in respect of any claim under the Warranties
       other than a claim in respect of the Tax Warranties or the Environmental
       Warranties shall cease on the second anniversary of Completion except in
       respect of matters which have been the subject of a bona fide written
       claim which is made before that date by or on behalf of the Purchaser to
       the Vendor which gives such reasonable details of all material aspects of
       the claim as are then available including the Purchaser's bona fide
       estimate of the amount thereof.

               PART 4 - TIME LIMITATIONS UNDER THE TAX WARRANTIES

11.    The liability of the Vendor in respect of any claim under the Tax
       Warranties shall cease on the sixth anniversary of Completion except in
       respect of matters which have been the subject of a bona fide written
       claim which is made before that date by or on behalf of the Purchaser to
       the Vendor which gives such reasonable details of all material aspects of
       the claim as are then available including the Purchaser's bona fide
       estimate of the amount thereof.

          PART 5 - ENVIRONMENTAL WARRANTIES AND ENVIRONMENTAL INDEMNITY

12.    The liability of the Vendor in respect of any claim under the
       Environmental Warranties or the Environmental Indemnity shall cease on
       the sixth anniversary of Completion, except in respect of matters which
       have been the subject of a bona fide written claim which is made before
       that date by or on behalf of the Purchaser to the Vendor which gives such
       reasonable details of all material aspects of the claim as are then
       available including the Purchaser's bona fide estimate of the amount
       thereof.

                            PART 6 - OTHER PROVISIONS

13.    Any claim which may be made in respect of the Warranties shall be deemed
       to be withdrawn (if it has not been previously satisfied, settled or
       withdrawn) unless legal proceedings in respect of such claim shall have
       been commenced by the Purchaser against the Vendor within 12 months of
       the date of notification of the claim save that where notification is
       made by the Purchaser of a claim which is contingent such claim shall be
       deemed to be withdrawn unless legal proceedings in respect of such claim
       have been commenced within 6 months of the claim crystallising.

14.    The rights of the Purchaser in respect of a breach of any of the
       Warranties shall not be affected by Completion.

15.    This SCHEDULE 8 which, inter alia, regulates or otherwise affects the
       liability of the Vendor shall remain in full force and be fully
       applicable in all circumstances and, in particular (but without
       limitation), shall not be discharged in whole or in part by any breach of
       any of the Warranties or any claim against the Vendor in respect of the
       Warranties, the Indemnities or the Deed of Tax Covenant, whatever its
       nature or consequences, nor by any other matter whatsoever.
