         a.       The Company shall pay the following amounts to a pension fund,
                  a provident fund or managers' insurance, at the choice
                  thereof:

<PAGE>

                  1)       8.33% of the Salary, as defined in clause 4(a), for
                           severance pay - at the Company's expense.

                  2)       5% of the Salary, as defined in clause 4(a), for
                           provident payments - at the Company's expense.

                  In the event that the payments to be made prior to termination
                  of your employment shall not suffice in order to cover the
                  severance pay due to you under this agreement, the Company
                  shall complement the payment within the period of time fixed
                  in the law.

         c.       Your consent to section (b) exempts the Company from the need
                  to apply to the Minister of Labor for his approval under
                  Article 14 of the Severance Pay Law; however, if such a need
                  for an application for an appropriate permit should arise,
                  your signing of this agreement shall constitute an
                  authorization of the Company to apply for the permit on your
                  behalf too.

         d.       Should the Company be required in future, whether by law or by
                  an expansion order which shall apply to the entire labor
                  market, to make payments to another comprehensive pension fund
                  or arrangement, such payment to the new applicable fund or
                  arrangement shall be in lieu of the arrangement herein, and
                  you will not be permitted to draw funds on account of the
                  payments made within the framework of the previous
                  arrangement, but subject to the regulations of the appropriate
                  fund.

9.       ADVANCED STUDY FUND

         During the Period of your Employment with the Company and subject to
         the General Manager's approval, the Company shall make payments to an
         advanced study fund to which you belong at the acceptable rate, i.e.,

         expense, and 2.5% at the employee's expense.

10.      CONFLICT OF INTERESTS

         You shall perform no act which shall derogate from your loyalty to the
         Company and/or which may place you in a conflict of interests with the
         Company's objectives. In addition, throughout the term of your
         employment, you shall work in no other occupation or employment without
         the Company's prior written approval.

         business nor be employed by such competing business, whether for or
         without remuneration, nor be directly or indirectly active in the
         management and/or operation of such competing business.

         This undertaking shall be valid for eighteen (18) months from the date
         of termination of my employment. For the purposes of this clause,
         "competing business" shall mean a business dealing with and/or
         marketing and/or manufacturing and/or developing products in which the
         Company shall have dealt or products in the process of being developed
         by the Company during the three years preceding the termination of my
         employment (hereinafter: the "Company's Products"). For the removal of
         doubt, the employee shall not be barred from working in a business
         dealing with products containing components of the same type as the
         Company's Products, so long as the employee shall not engage, whether
         directly or indirectly, in the development, manufacture or marketing of
         components which may compete with the Company's Products.

PART III - VARIOUS BREACHES

8.       In any case in which I shall breach my foregoing undertaking or part
         thereof, I shall be obliged to compensate the Company for all the
         damages and/or expenses which the Company shall incur due to such
         breach, without derogating from any other remedy available to you
         against me under any law due to the breach of my foregoing
         undertakings.

9.       This undertaking is attached to the employment agreement signed between
         myself and the Company on JUNE 2, 1993 and constitutes an integral part
         thereof. This undertaking does not derogate from any undertaking
         imposed on me as an employee of the Company pursuant to the said
         agreement and/or any law.

10.      I am aware that this undertaking contains limitations to which I shall
         be subject after termination of my employment with the Company. I am
         signing the same after having considered the matter and been given time
         to consult with a professional.
