           Accounts and TCC agrees that the Managers' Accountants shall be at

1.   General Requirements

     Subject to the provisions set out below, the Option Accounts shall be
     prepared under the historical cost convention and in accordance with
     accounting principles generally accepted in the United Kingdom (including
     Accounting Standards) and, subject as aforesaid, on a basis consistent with
     the balance sheets and profit and loss accounts of each company within the
     Group (other than AVH) made up to 31 March 1997.

2.   Balance Sheet

2.1  For the purpose of preparing the balance sheet in the Option Accounts the
     following principles shall be applied:-

     2.1.1 sums receivable in respect of debtors shall not be included at sums
           higher than the amounts collectable, making appropriate provision for
           doubtful debts;

           net realisable value;

     2.1.3 liabilities shall include accruals at the close of business on the
           date of the Option Accounts;

     2.1.4 immovable property and other fixed assets shall be included at their

           (a)  plant and machinery           3-7 years;

           (b)  fixtures and fittings         3-7 years;

          disposal of any immovable property or from any revaluation of
          immovable property or surpluses or deficits arising on currency

          deficits are treated in the said accounts as items of an extraordinary
          or exceptional nature;

     3.2  depreciation shall be deducted on the basis and by reference to the
          rates mentioned in PARAGRAPH 2.1.4 above;

     3.3  any taxation on profits and any subvention or other payment to any
          other company in lieu of payment of any such tax or in consideration
          of a surrender of group relief by the other company shall not be
          deducted; and

     3.4  the profits or losses shall be computed before paying any dividends by
          AVH or making appropriations of profit or allocations to or from
          reserves and before deducting any extraordinary item or making any
          prior year adjustment, as defined in SSAP 6.

                            Part 2 - Adjusting Events

1.   If the A Directors determine that AVH or any of the Subsidiaries shall
     undertake any of the matters in CLAUSE 5.1 or in PARAGRAPH 4 below then:-

1.1  subject to PARAGRAPH 1.2 below, if the B Directors (on behalf of the
     Managers) shall approve any such matters their effect shall be taken into
     account in the preparation of the Option Accounts and the calculation of
     the Principal Amount, the First Option Price and the Second Option Price;
     but

1.2  if the B Directors (on behalf of the Managers) shall object to any such
     matters or shall agree to such matters but only on the condition that the
     effect of such matters be excluded from the Option Accounts their effect
     shall be excluded from the Option Accounts and the calculation of the First
     Option Price and the Second Option Price.

2.   If the A Directors (on behalf of TCC) and the B Directors (on behalf of the
     Managers) are unable to agree on the method by which the effect of any of
     the matters in PARAGRAPH 4 below is to be taken into account or excluded
     from the Option Accounts points in dispute shall be referred to the
     decision of an independent chartered accountant (the "Independent
     Accountant") to be appointed (in default of nomination by agreement between
     the A Directors and the B Directors) by the President for the time being of
     the Institute of Chartered Accountants in England and Wales.

3.   The Independent Accountant shall act as an expert and not as an arbitrator,
     the Arbitration Acts 1950 and 1979 shall not apply and his decision on the
     matter in dispute shall (in the absence of manifest error) be final and
     binding on TCC and the Managers. The costs of the Independent Accountant
     shall be apportioned between TCC and the Managers as the Independent
     Accountant shall decide but each party shall be responsible for its own
     costs of presenting its case to the Independent Accountant.

4.   The matters which may lead to an adjustment to the preparation of the
     Option Accounts are those matters listed in CLAUSE 5.1 of the Agreement and
     in addition are:-

4.1  AVH or any of the Subsidiaries incurring any lease obligations,
     indebtedness for borrowed money or issuing any debt securities or assuming,
     guaranteeing or endorsing the obligations of any other individual entity in
     an amount that, individually or in the aggregate, exceeds 'L'100,000;

4.2  the taking of any action which is other than consistent with best practice
     with respect to the grant of any severance or termination pay to employees

     termination pay policies or agreements of the Subsidiaries in effect at the
     date of this Agreement;

4.3  the adoption of or amendment to any bonus, profit sharing, compensation,
     share option, pension, retirement, deferred compensation, employment or
     other employee benefit plan, agreement, trust, fund or other arrangement
     for the benefit

                                       iv







     or welfare of any employee of AVH or any of the Subsidiaries, or any
     increase in any manner in the compensation or fringe benefits of any
     employee or payment of any benefit to any employee not required by any
     existing plan, arrangement or Agreement;

4.4  the making of any tax election or claim or settlement or compromise of any
     material tax liability of AVH or any of the Subsidiaries;

4.5  the hiring of any Level 1/ Level 2 employees by AVH or any of the
     Subsidiaries;

4.6  any purchase of equipment by AVH or any of the Subsidiaries in excess of
     'L'75,000;

4.7  the making of any loans to any employees or officers of AVH or any of the
     Subsidiaries;

     AVH or any of the Subsidiaries that would have a significant impact on the
     sales activities of AVH or the Subsidiaries or Cooper Vision;

4.9  the termination by any of the Subsidiaries of any existing contractual
     obligations and relationships with customers and/or distributors;

     manufacturing sub-contract arrangements;

     manufacturers and/or subcontract licensees;

4.12 the instigation of any legal action which is likely to result in AVH or any
     of the Subsidiaries incurring expenses in excess of 'L'30,000.

     PROVIDED THAT any of the matters listed above may be undertaken by
     resolution of a simple majority of the Directors without the need for an A
     Director or a B Director to vote in favour of the resolution where such
     matters are provided for in the business plan provided by Mr. Galley at the
     date hereof.

                                       v







                                   SCHEDULE 3

1.   Each of the First Option Price and the Second Option Price for each
     Remaining Share shall be calculated by reference to the following:-

                                   (A + B + C)
                                   -----------
                                     10,000


     where

     A =  Ten per cent. of the pre-tax profits (or losses) of the Group as
          shown by the Option Accounts for each of the financial years ending on
          the Balance Sheet Date in each of 1998, 1999 and 2000 multiplied by a
          factor of 2.07, 2.07 and 8.28 respectively. Net losses shall be
          treated as a negative number and deducted from net profits for the
          purpose of the calculation. In no circumstances can A itself be a
          negative number.

     B =  'L'5,000,000.

     C =  half of the post tax savings realised by CooperVision from a
          manufacturing improvement introduced by the Group to CooperVision,
          such savings being the saving accruing to CooperVision in the first
          year of the use of such improvement.

     PROVIDED ALWAYS THAT if the turnover for the Group falls below
     'L'250,000,000, 'L'27,500,000, and 'L'30,250,000 in the years ending on 31
     October in 1998, 1999 and 2000 respectively, the First Option Price and the
     Second Option Price for each Remaining Share shall be the nominal value
     (10p) of each such Share.

2.   The Principal Amount of the EOLN shall be calculated by reference to the
     following:-

                                (A + B + C) - Z

     where

     A and B = are as defined above.

     Z =       the aggregate amount calculated pursuant to paragraph 1 above to
               acquire all the Remaining Shares.
