          SECTION I      SCOPE OF FUNCTIONS/MANAGERIAL AND REPRESENTATIVE
                         RIGHTS/ADDITIONAL OCCUPATIONS

          1.1  The Managing Director is responsible together with the other
               managing directors for the management of the company and its
               outward representation.  He manages the company and is
               responsible for all its commercial activities.

          1.2  The Managing Director must comply with all applicable laws
               and the company's shareholders' agreement in managing the
               company, whereby the decisions of the shareholders' meeting
               are to be respected and carried out.

               He is entitled to perform all normal business on his own
               initiative and is sole authorized signatory for such
               activities.  He must first obtain the shareholders'
               agreement in those special cases stipulated in the
               shareholders' agreement and for legal actions outside the
               scope of normal business activities which are not

               occupation or participate in another commercial undertaking
               in the same line of business as the company with the
               agreement of a shareholders' meeting.  The same applies to
               the acceptance of seats on supervisory boards, advisory
               boards or similar bodies, including honorary offices of any
               kind.

          SECTION 2 EMOLUMENTS/EXPENSES AND ALLOWANCES/SICKNESS

          2.1  The Managing Director will receive the following emoluments
               for his activities.

               A.   A monthly gross salary of fifteen thousand German
                    Marks.

               B.   A share in the annual profits as calculated for tax
                    purposes before adding the trade tax reduction due to
                    payment of this share and after deduction of those
                    company expenses not tax-deductible insofar as the
                    employment relationship has subsisted throughout the
                    entire year amounting to 15% (fifteen percent), payable
                    after approval of the relevant annual accounts by the
                    shareholders' meeting.

                    In the event of payment on a loan basis, interest is
                    payable to the company at the rate of seven percent per
                    annum, beginning with the first day of the financial
                    year following the date of transfer or of crediting of
                    the money.  Any such loan is subject to quarterly
                    notice of termination.

               C.   Special payment can be made for overtime, Sunday and
                    holiday work, but only when the Managing Director was
                    demonstrably not at his usual place of work, i.e.
                    overtime was incurred during traveling on business,
                    congresses, etc.

               D.   In addition to the emoluments mentioned above, the
                    Managing Director will also receive the employer's
                    portion of all social security payments due, or a
                    comparable sum in the event that no obligation to make
                    such payments exists.

                    The company has taken out direct accident insurance
                    with guaranteed refund of contributions as company
                    pension.  This insurance began on the first of

                    capital payment in the event of death and an annuity
                    option was taken out on the eleventh of February, 1994
                    on the Managing Director's life.

                    company's usual social security benefits and services.

               F.   The Managing Director will receive a thirteenth month's
                    salary as Christmas bonus.

          2.2  Travelling and other expenses necessarily incurred on the
               company's behalf will be appropriately recompensed.  All
               such expenses exceeding the permissible limits in taxation
               law must be documented.

               The Managing Director has a right to a company car, which he
               may also use privately.  The payment of tax on the financial
               benefit involved is due in accordance with the tax
               authorities' guidelines.

          2.3  The company is entitled to reduce the Managing Director's
               emoluments as appropriate should he be absent from work due
               to illness, accident or other causes for more than 12 weeks.

               only be made by shareholders' decision.

          SECTION 3 HOLIDAY

          The Managing Director is entitled to thirty working days holiday
          per annum.  This is to be taken with due regard to the company's
          affairs and at such a time as not to damage the company in any
          way.

               regarding all the company's affairs toward all outsiders
               unless passing on such information is essential in the
               normal course of his duties.  This obligation remains in
               force when this Contract expires.

          SECTION 5 DURATION OF EMPLOYMENT, PERIOD OF NOTICE

          5.1  The employment relationship has existed since the first of

               party to it, the period of notice being six months to the
               end of a company financial year.

          5.3  An important reason in the person of the Managing Director
               making continuation of the employment relationship
               intolerable to the company must exist, as well as an
               appropriate shareholders' decision, before the company may
               terminate this Contract.

          5.4  The company is entitled to send the Managing Director on
               leave of absence with full pay in the event that lawful
               notice of termination of this Contract has been served. 
               Such leave is to be deducted from any annual holiday
               entitlement the Managing Director may have remaining at the
               time.

               property entrusted to him on loan, to keep same under lock
               and key and to return them to the company in full on expiry
               of this Contract without being asked to do so.  The company
               will then decide whether to retain all or any such documents
               and records.

          SECTION 7 CHANGES TO THIS CONTRACT
