                    Scope of Managing Director's Authority

(1) The Managing director's authority extends to all actions associated with the
    Company's usual business operations. In order to perform the following
    actions the Managing Director will require the approval of the shareholder,
    even if in an individual case they form part of the Company's usual business
    operations:

    a) relocation of the administrative centres, selling of significant parts
       (assets) of the Company, the setting up or closing down of branch
       offices, the founding, acquisition or selling of other companies or the
       securing of an interest in such companies, the initiation and/or
       discontinuation of existing areas of activity;

    b) the acquisition, selling or encumbering of real property or equivalent
       rights in real property;
<PAGE>

        c) the conclusion, termination or amendment of contracts between
           companies;

        d) entering into liabilities on bills, the assumption of suretyship
           obligations or the issue of guarantee undertakings, unless these are
           required for a particular business transaction within the context of
           usual business operations;

        e) the granting of loans in excess of DM 50,000.--in an individual case,
           or if the credit is to be granted to the Managing Director, his
           spouse, relatives or in-laws.

(1) -- (4) remain effective unchanged.


                                     (S)3
                             Duration of Contract

(5) If the employment relationship is terminated by the Company, the Managing
    Director will receive a lump sum settlement amounting to his total monthly
    remuneration: the monthly average of the share in profits actually paid
    ((S)4 paragraphs 1 and 2) over the last 24 months (monthly average) will be
    added to the salary paid world-wide. The lump sum settlement will be paid
    for each year of employment and will amount to no less than 6 times and no
    more than 12 times this average. This does not apply if notice has been
    given on grounds of conduct for which the Managing Director is answerable
    and which entitle the Company to terminate employment without notice. The
    Company must provide evidence of the conditions in clause 2.

                                     (S)4
                                 Remuneration

(1) Basic salary

As of 01.01.2000 36% of the Managing Director's salary will be paid from the USA
and 64% from Germany. This is based on the hours worked at the two locations in
Berlin and Waltham.

With effect from 01.06.2000 the Managing Director will receive a fixed annual
salary of DM 400,000.--, payable in twelve equal instalments, one at the end of
each month, plus the employer's contributions (statutory social security pension
insurance, health insurance, unemployment insurance and care insurance). Here
the different locations will retain the aforementioned percentage split for the
salary payments.

(2) The Managing Director will also be given an interest in the Management
    Incentive Plan (MIP) -- there is no entitlement to payment -- amounting to
    up to 35% of his annual salary on the basis of the applicable regulations.

The other provisions of the contract remain unchanged.
