[Address of the independent director]

                                                                          [Date]

Dear [*]

We hereby write to confirm the terms and conditions of your appointment as an
independent director of the Company:-

1.   Subject to Clause 8 herein, your appointment as an independent director of
     the Company will be for an initial term of three years and will take effect
     from the date hereof, and will continue thereafter for successive
     three-year terms until terminated by you or removed by our shareholders
     with three months' notice in writing served on the other party.

2.   Your role will be that of an independent director, bringing an objectivity
     and independence of view borne by your outside experience, helping the
     board of directors of the Company (the "BOARD") to provide the Company with
     effective leadership and ensuring the continuing effectiveness of the
     management team and the high standards of probity within the Company. As an
     independent director, the Board may ask you to become a member of the
     various committees of the Board including the audit committee whose
     principal duties include, inter alia, the review and supervision of the
     Company's financial reporting process and internal controls.

3.   In addition to your general fiduciary responsibilities, you shall
     faithfully and diligently perform such functions and exercise such powers
     as are appropriate to your position as an independent director. The Board
     may ask you to accept additional appointments in or on behalf of the
     Company.

4.   In order to satisfy the requirements of a public company, you are expected
     to attend general meetings (the "GENERAL MEETINGS") of the Company, each
     meeting of the Board and of any committees to which you are appointed as a
     member. If you are unavoidably unable to attend, as much prior notice as
     possible should be given to the chairman of the Board (the "CHAIRMAN").

5.   You will be fully reimbursed for all reasonable out-of-pocket expenses you
     incur in discharging your duties on production of appropriate proofs of
     payment. The Company's procedures require you to obtain authorisation in
     advance from the Chairman for any item of expenditure that are to be
     reasonably incurred by you and any

<PAGE>

     expenses to be reasonably incurred overseas or for foreign travel.

6.   Because of your independent status, you are not eligible to participate in
     any share option, bonus schemes or other benefits of the kind available to
     executive and other directors of the Company, except as expressly approved
     by the Board at its sole discretion.

7.   You shall be entitled to an annual fee of HK$[_] payable in arrears in
     December each year, which shall accrue on a daily basis.

8.   Your appointment will, in any event, cease at the annual General Meeting of
     the Company immediately before the expiration of your initial term or any
     subsequent three-year term, as the case may be, as set forth in Clause 1
     and you will be eligible for re-election at the annual General Meeting. In
     addition to these requirements, your appointment will at all times be
     terminable by three months' prior written notice given by either side.

9.   Your appointment will terminate automatically and immediately upon written
     notice to you without further compensation (for avoidance of doubt, you
     will be entitled to compensation for your past service as set forth herein)

          association;

     9.2  are removed for cause from office as a director by any resolution duly
          proposed and resolved by the members of the Company in General Meeting

          poll will count); or

     9.3  are not re-elected as a director when you submit yourself to

     10.1 to maintain the confidentiality of all information you acquire by
          virtue of your appointment;

     10.2 to act in good faith in the Company's interests at all times;

     10.3 to act at all times for the proper purposes of the Company;

     10.4 to carry out your responsibilities with the care, skill and diligence
          which the Company is reasonably entitled to expect from someone of
          your experience and expertise; and

     continuing basis of all changes to such arrangements.

13.  You have the responsibility to act in the best interests of the Company and
     the Group and to refrain from any conduct that would be, or may appear to

     refrain from voting on a matter in which you, any member of your family or
     any persons affiliated with you, may have a conflict. A "conflict of
     interest" exists when the private interest of yourself, any member of your
     family or any persons affiliated with you, is inconsistent with or opposed
     to, or gives the appearance of being inconsistent with or opposed to, the
     interests of the Company or the Group.

14.  You shall not, either during the term of your appointment as an independent
     director of the Company or thereafter:-

     14.1 use to the detriment or prejudice of the Group or divulge or

          concerning the business or affairs of the Group (except to employees
          or directors of the Group whose province is to know the same) which
          may have come to your knowledge during the term of your appointment
          hereunder; or

     14.2 use for your own purpose or for any purposes other than those of the
          Group or disclose to any third party (except to regulatory authorities
          or required by any applicable law) any information or knowledge of a
          confidential nature which you may from time to time acquire in
          relation to any member of the Group but so that this restriction shall
          cease to apply to any information or knowledge which may come into the
          public domain (otherwise than through your fault).

15.  You shall not, during the term of your appointment and for one year
     thereafter, be a director or employee or agent of, or have any other
     material financial interest or involvement in, any business or enterprise
     which competes or is likely to compete (directly or indirectly) or has a
     significant business relationship with any Group company without the prior
     written consent of the Board.

16.  You shall promptly upon request by the Company or in any event upon your
     ceasing to be an independent director of the Company deliver up to the
     Company all lists of clients

     retain any copies thereof. Title and copyright therein shall vest in the
     Company.

     independence and other requirements of the Securities and Exchange
     Commission of the United States.
