3.      THE OBJECT OF THE TRUST

        The object of the trust is for options to shares to be held by the
        Trustee for the benefit of employees of the Company whose names appear
        in List "1" attached to this Agreement, as may be amended from time to
        time by the Company by written notice to the Trustee detailing the names
        of the beneficiaries and next to each beneficiaries' name, the number of
        options which the Trustee holds or shall hold in trust for each
        beneficiary.

        3.1     The Trustee shall maintain and manage List "1" and shall attend
                to updating it from time to time as required, including adding
                new beneficiaries, recording options that have been allotted to
                the Trustee on behalf of the beneficiaries according to the
                ratio of their rights at the determining date, and he shall also
                record the options that shall be added to the beneficiaries from
                such allotment in List "1" to the credit of such beneficiaries.

        3.2     The share options allotted upon exercise of the options shall be
                allotted to the Trustee or that shall be held by the Trustee
                pursuant to the provisions of this Agreement shall be registered
                in the Trustee's name in the Company's register of shareholders.

        3.3     The Trustee shall act in all matters relating to adding new
                employees to List "1" and to determine the terms and conditions
                of their entitlement pursuant to resolutions of the Company as
                shall be passed from time to time. Nonetheless, the Trustee
                shall not be entitled to detract from the rights and conditions
                prescribed and/or that shall be prescribed for the beneficiaries
                pursuant to this Agreement except with the prior written consent
                of the Company and of the beneficiary or beneficiaries affected
                by such change, as the case may be.

        3.4     The beneficiaries included or that shall be included in List "1"
                at any time whatsoever do not and shall not have any right or
                claim against other beneficiaries being added to List "1" or
                against the adding of rights or shares to those included in List
                "1", in whole or in part.

        3.5     Upon the fulfillment of the terms and conditions or at the
                specified times, all pursuant to the terms and conditions
                hereof, the Trustee shall transfer to the beneficiaries the
                options or the shares allotted to them, as the case may be, all
                subject to the provisions hereof, the provisions of the
                Ordinance and the Regulations.

4.      THE TRUSTEE'S DUTIES AND POWERS

<PAGE>   4
        The Company and the beneficiaries hereby instruct the Trustee to act
        with the options which it holds and with the rights deriving therefrom
        in the following manner:

        4.1     The Trustee shall apply to the authorities in a request for
                approval of the trust as obligated by the provisions.

        4.2     If the Company shall distribute bonus shares during the term of
                the trust, the bonus shares that shall be distributed to the
                Trustee in respect of the options pursuant to this Agreement
                shall belong to the beneficiaries and they shall be credited to
                them pro rata to their entitlement to the options according to
                List "1", and at the date of the end of the trust and the
                transfer of the shares to the beneficiaries, the Trustee and the
                Company shall act to allot the bonus shares to them
                simultaneously with the allotment of the shares due pursuant to
                the options.

        4.3     If rights in respect of the options are distributed by the
                Company at the end of the trust, the Trustee shall give prior
                written notice thereof to the beneficiaries in sufficient time
                to receive their response and it shall act in accordance with
                the beneficiaries' instructions. If the beneficiaries wish to
                register the rights and they transfer the amount required
                therefor to the Trustee, the Trustee shall purchase the rights
                on their behalf or on behalf of some of them and they shall be
                added to their rights at the end of the trust. If the
                beneficiaries do not give notice or if the beneficiaries do not
                reply to the Trustee at the time prescribed therefor, the
                Trustee shall deem the beneficiaries who did not reply or who
                did not pay the fixed consideration on due date as having
                irrevocably waived the offered rights.

        4.4     The Trustee shall act in its exclusive discretion regarding all
                the other subjects or rights conferred pursuant to the options
                or the shares upon exercise of the options. However, if the
                Trustee receives rights or monies in respect of the options,
                save for bonus shares, it shall transfer them to the
                beneficiaries pursuant to their proportionate share of the
                options pursuant to List "1".

        6.2     The terms and conditions:

                The Participating Employee's right to convert the options held
                in trust on his behalf by the Trustee into shares that shall be
                actually allotted in his name is conditional and suspensive upon
                the fulfillment of all the following terms and conditions:

                6.2.1   Every actual period of employment with the Company of at
                        least 24 months from the participation date shall confer

                        shares specified in the options into shares.

                6.2.2   Every month of continuous and cumulative period of
                        employment exceeding the first 24 months shall confer
                        the right to convert a further 1/36 (one thirty sixth)
                        from the balance of 2/3 (two-thirds) of the total number
                        of shares specified in the option, into shares actually
                        allotted, in an allotment at the end of the cumulative
                        period..

                6.2.3   After a continuous and cumulative actual period of
                        employment with the Company of 48 months, the

                        of the trust in relation to him shall expire.

                6.2.4   The exercise of the right to an actual allotment is
                        further conditional and suspensive upon the payment of

                        authorities as conditions for approval of the
                        fulfillment of this Agreement, the beneficiaries agree

        6.3     If the employee ceases to be an actual employee of the Company

                or part thereof into shares and prior to the actual allotment of
                shares, regardless of the reason for termination of employment
                in the Company, the employee's rights to the allotment of
                options or the exercise of the balance of the allotment in
                accordance with this Agreement, shall expire, be cancelled and
                be nullified and the Trust for the same employee shall expire.

                In the event that a beneficiary who ceased to be an employee
                within two years from the date of this Option Agreement and the
                tax exemption does not apply to the beneficiary, the same
                employee shall be liable for the tax payment for tax upon
                allotment and for tax pursuant to section 102 of the Ordinance,

<PAGE>   7
        6.4     If the options are cancelled because the terms and conditions of
                this clause have not been fulfilled, the employee shall not be
                entitled to consideration, refund or compensation or indemnity
                whatsoever in respect of the cancellation.

7.      THE BENEFICIARIES' LIABILITY

        7.1     The Beneficiaries are aware that the Trustee may hold options on
                their behalf which are not fully paid up, whether they are
                options under this Agreement or additional rights as specified
                in section 4 above, and in the event that a demand for payment
                is received for the conversion of the options into shares or
                other rights that are conditioned on payment, the Beneficiaries
                shall pay the required sums immediately upon receipt of a
                request from the Trustee in connection with it. Failure to
                satisfy this requirement may bring to such results as if the
                Beneficiaries ceased to be employed in the Company.

        7.2     Every liability and every amount that a holder of the options is
                under a duty to pay and all the obligations applicable pursuant
                to the Companies Ordinance and the Company's documents of
                incorporation to a holder of options or shares or a member of
                the Company, shall be passed on from the Trustee to the
                beneficiaries pursuant to the proportion of the options or the
                shares held by the Trustee for the benefit of the beneficiaries.

        7.3     The beneficiaries hereby confirm that they acknowledge that if
                payment demands of them are not complied with, the Company may
                forfeit the options held on their behalf by the Trustee pursuant
                to the Company's Articles of Association and the results of the
                forfeiture shall apply to each beneficiary in accordance with
                the option for shares held on trust on his behalf by the
                Trustee.

        7.4     If the Trustee receives demands, requests, notices and claims,
                including payment calls, demands for payments at the time of the
                Company's winding up, notices in respect of forfeiting the
                shares or any other demand, the Trustee shall, immediately upon
                the receipt thereof, send them to each of the beneficiaries in
                respect of whose shares held on his behalf by the Trustee the
                said demands were received, to the beneficiary's address as
                appearing in his participation notice or to another address
                which the beneficiary sent the Trustee, provided that they shall
                be sent in writing and the liability deriving from the said
                demands shall apply to the beneficiary alone.

        7.5     The beneficiaries' liability pursuant to this clause shall apply
                in accordance with the shares held on their behalf. If any
                charge or payment demand whatsoever shall relate to shares held
                for a number of beneficiaries, each beneficiary shall be liable
                for the charge or the payment demand pro rata to the options
                held on his behalf.

8.      TERMINATION OF THE TRUST

<PAGE>   8
        8.1     If the Trustee holds options or shares for any beneficiary,
                during the Vesting Period that shall not be less than two years,
                the shares or options shall be transferred to the beneficiary's
                possession either on its own initiative or on the beneficiary's
                initiative, on the following terms and conditions:

                8.1.1   The Company notified the Trustee that the employee is
                        continuously employed by the Company for the whole
                        vesting period, and continues to be employed by the
                        Company and he has requested to exercise an option and
                        has paid the Company the exercise price.

                8.1.2   In the event that the Notification of Deduction at
                        Source Form has been completed and sent, as specified in
                        the Income Tax Regulations (Tax Relief Upon Allotment of
                        Shares to Employees) 1989, and tax is actually paid, at
                        the rate specified in the Regulations at that time.

        8.2     If a Participating Employee ceases to be employed by the Company
                at any time whatsoever and for any reason whatsoever, the trust
                for him shall expire at the time of the termination of
                employee-employer relations. Expiration of the Trust upon
                termination of the employee-employer relationship will be
                relative to the balance of the right of the Beneficiary at such
                time.

        8.3     If a Participating Employee exercises a right as a beneficiary
                by way of exercising the conversion of an option into a share
                that shall be actually allotted, subject to all the terms and
                conditions of this Agreement, the trust shall expire in respect
                of the part of the option converted and actually allotted at
                such time.

9.      ISSUE TO THE PUBLIC

        9.1     If the Company notifies the Trustee that for the purposes of an
                issue of shares to the public an undertaking by the beneficiary
                option holders is required, pursuant whereto they undertake a
                restriction on the transfer of the shares of which they are
                beneficiaries or to which they are entitled pursuant to the
                options or the trading of such shares, the Trustee shall be
                entitled to assume the undertaking as aforesaid, provided that
                such an undertaking shall not prevent it transferring options to
                the beneficiaries, subject to the beneficiaries assuming the
                said undertaking.

        9.2     If as a condition for the issue of shares to the public the
                option holders shall be required to undertake not to sell them
                during a specific period (hereinafter referred to as "the
                restriction period"), the Company is entitled to make demand of
                the Trustee to join in giving an undertaking as aforesaid, and
                in the event of a demand as aforesaid the Trustee shall accede
                thereto, even if the Vesting Period, or part

<PAGE>   9
                thereof,mentioned in clause 6 above, has not yet terminated, and
                in such case the trust period shall be extended by the
                restriction period and the beneficiaries shall have no complaint
                in consequence thereof.

        9.3     The beneficiaries are aware that the Company is considering an
                issue to the public with the intention of listing the Company's
                shares for trading on a stock exchange either in Israel or
                abroad. The beneficiaries empower the Trustee to sign any
                document which, in the opinion of the Company's board of
                directors, is required to enable an issue as aforesaid,
                including changes to the Company's documents of incorporation
                and including changes in its capital structure, provided that
                the changes shall not result in the shares the subject of the
                options held in trust by the Trustee having inferior rights
                (save for voting rights) compared with the rights which other
                shares of the Company confer.

                In the event that the shares are registered for trading, as
                aforesaid, the employee shall be permitted to apply to the
                Commissioner in a request that his shares will be seen as sold
                pursuant to the average stock exchange price-list in the first
                three days of trading.

10.     NON-TRANSFERABILITY

        The rights to the options pursuant to this Agreement and the shares that
        shall be allotted to the Participating Employee pursuant thereto and
        upon the terms and conditions thereof are granted to the Participating
        Employee as a beneficiary and to him alone.

        The beneficiaries' rights may not be transferred or assigned in any
        manner whatsoever, including by way of pledge, charge, attachment,
        assignment and the like.

        Without derogating from the foregoing, rights to options may only be
        transferred by way of implementing a will of an employee or his
        inheritance if the employee dies on a date when he was an actual
        employee of the Company.

11.     REPLACEMENT TRUSTEE

        If the Trustee is unable to perform its duties or does not wish to
        perform its duties, the Company is entitled to appoint another trustee
        and in such event the Trustee shall transfer the options it is holding
        to the other trustee and the replacement trustee shall replace the
        Trustee for all intents and purposes.

12.     THE COMPANY'S OTHER SHARES

        12.1    The provisions of this Agreement do not prejudice the rights of
                other holders of options or shares of the Company to which the
                trust arrangement does not apply.

        12.2    The parties are aware that additional employees of the Company
                own rights in

<PAGE>   10
                shares or to receive shares in other arrangements, and it is
                hereby expressly agreed that this Agreement does not apply to
                and does not affect or howsoever impair rights of other
                shareholders of the Company or persons entitled to shares of the
                Company, including employees entitled as aforesaid.

13.     PAYMENT AND INDEMNITY

        13.1    An action by the Trustee and any outcome of an action by the
                Trustee, directly or indirectly, shall not render the Trustee
                liable for any payment whatsoever. In any event in which the
                Trustee is directly or indirectly ordered to make any payment in
                connection with its actions as trustee, the Company undertakes
                to directly effect and make the payment which shall be required,
                for so long as it is a payment relating to the trust, or to
                indemnify the Trustee for a payment as aforesaid upon demand
                received from it.

        13.2    Save in regard to the subjects detailed in clause 7 above, if
                the Trustee is ordered to make any payment by a court or
                tribunal or arbitrator in consequence of its operations as
                trustee, whether directly or indirectly, the Company shall bear
                the payment in its stead and shall effect the payment on the
                required date, and the Trustee shall not be liable to indemnify
                the Company for such payment.

        13.3    The beneficiaries and the Company release the Trustee from any
                liability for a negligent act or omission, and the Company shall
                indemnify the Trustee for any payment which it is required to
                pay in order to compensate any person or corporation for such an
                act or omission.

14.     GENERAL PROVISIONS

        14.1    If the law so obliges or if the Company or any of its
                shareholders so requests, the Company shall procure that the
                Trustee shall be registered in the Company's register of
                shareholders as the owner of the options for shares held by it
                on trust.

        14.2    The Company shall pay the Trustee's remuneration.

        14.3    If the Company resolves to issue any of its shares in
                consequence of additional investors joining the Company or for
                any other reason, the Trustee's part of the options convertible
                into shares of the Company shall be diluted accordingly and the
                beneficiaries' right shall also be diluted in accordance
                therewith, and the beneficiaries shall not have any complaint or
                claim in such regard.

        14.4    In a case where the beneficiaries have been actually allotted
                part of the shares at the time of a dilution as aforesaid or at
                any other time thereafter, their shares shall be diluted in
                respect of the joining of investors or other shareholders, and
                the beneficiaries shall not, even as shareholders, have any
                complaint or demand in such regard.

<PAGE>   11
        14.5    The Trustee is empowered to determine the terms and conditions
                for beneficiaries participating in the trust, in its discretion.

        14.6    The parties undertake to sign all the documents required to give
                validity and effect to this Agreement.

        14.7    If income tax or capital gains tax or any other tax applies in
                respect of the options or in respect of the allotment of the
                shares or in respect of the holding of the shares or the
                transfer thereof, or for another reason, the tax shall be borne
                by the beneficiary in respect of the options or the shares held
                for his benefit by the Trustee. If tax as aforesaid is imposed,
                the Trustee shall be entitled to make demand of the beneficiary
                to pay the tax upon demand pursuant to this Agreement or to
                deduct the imposed tax from the amounts due or that shall be due
                to the beneficiary, and such being in addition to any other
                remedy available to the Trustee at law. If the tax as aforesaid
                is imposed upon the Company, the Trustee shall be under a duty,
                upon the Company's demand, to deduct the said tax and to remit
                the amount collected to the Company, as the case may be.

                The beneficiary authorizes and empowers the Company and the
                Trustee to deduct or collect tax as aforesaid.

        14.8    In the event of the death of a beneficiary at a time when he is
                not an actual employee of the Company, his rights shall
                automatically expire and any prima facie transfer to his heirs
                or to beneficiaries pursuant to his will, as the case may be,
                shall not be valid, unless the Company confirms that as at the
                date of the death the was an actual employee.

      REGULATIONS (TAX RELIEF UPON ALLOTMENT OF SHARES TO EMPLOYEES) 1989
                              (THE "REGULATIONS")

1.      In accordance with section 3 of the Regulations, we hereby inform you
        that IET Intelligent Electronics Ltd. (hereinafter the "Company") has
        decided to adopt a share option plan, in accordance with section 102 of
        the Income Tax Ordinance and in accordance with the Regulations, whereby
        within its framework, employees of the Company will be allotted options
        in an entitling allotment, as specified in the Regulations.

2.      The date of the allotment of options within the framework of this plan
        shall not be prior to 1.1.97 and not later than 31.12.2001.

3.      B. A. Trustees shall become the Trustee for the fulfillment of this plan
        (hereinafter the "Trustee"). The appointment of the Trustee has been
        approved on August 25, 1996 by the Tax Commissioner's Office in
        accordance with his authority under section 102 of the Ordinance.

4.      A. In accordance with section 4(B) of the Regulations, the Company
        hereby undertakes towards the Income Tax Assessor that if bonus shares
        are allotted to an employee under the options allotted for him in the
        framework of the entitling allotment, they shall be forwarded to the
        Trustee as long as the Trustee holds for him options allotted for the
        employee within the framework of the entitling allotment. The Trustee is
        obligated to the Income Tax Assessor to apply the provisions of section
        102 to the said bonus shares, as if the bonus shares were options
        allotted to the employee in the framework of the entitling offer.

                2nd.    In accordance with section 4(B) of the Regulations, we
                        confirm that we hold a confirmation letter from the
                        employee that he agrees that the arrangement shall apply
                        to him and that he undertakes not to request a tax
                        exemption under sections 95 or 97(A) of the Ordinance or

        of the consideration for the account upon which tax applies.

        required to be paid as a condition for the transfer of options (or
        shares) for the employee submitted by the Company or the employee to the
        Trustee, the Trustee shall transfer the options into shares for the
        employee but only after the sum of tax determined in the Income Tax
        Assessor's approval has been paid.

Yours sincerely,

     3.1  The Trustee shall maintain and manage list 1 and shall attend to
          updating it from time to time as required, including adding new
          beneficiaries, recording options that have been allotted to the

          options that shall be added to the beneficiaries from such allotment
          in list 1 to the credit of such beneficiaries.

     3.2  The shares the subject of the options that shall be allotted to the
          Trustee or that shall be held by it pursuant to the provisions hereof
          shall be registered in the Trustee's name in the Company's register
          of shareholders.

     3.3  The Trustee shall act in all matters relating to adding new employees
          to list 1 and to determine the terms and conditions of their
          entitlement pursuant to resolutions of the Company as shall be passed

          detract from the rights and conditions prescribed and/or that shall
          be prescribed for the beneficiaries pursuant to this agreement or
          with the written consent of the Company and of the beneficiary or
          beneficiaries as the case may be.

     3.4  The beneficiaries included or that shall be included in list 1 at any
          time whatsoever do not and shall not have any right or plea against
          others joining list 1 or against the adding of rights or shares to
          those included in list 1, in whole or in part.

     3.5  Upon the fulfillment of the terms and conditions or upon the times
          falling due, all pursuant to the terms and conditions hereof, the
          Trustee shall transfer to the beneficiaries the shares allotted to it,

          and the provisions of the Rules.

4.   The Trustee's Duties and Powers

     The Company and the beneficiaries hereby instruct the Trustee to act with
     the options which it holds and with the rights deriving from the holding
     thereof in the following manner:

     4.1  The Trustee shall submit an application to the authorities to approve
          the trust as obliged from the Rules.

     4.2  If the Company shall distribute bonus shares during the term of the
          trust, the bonus shares that shall be distributed to the Trustee in
          respect of the options pursuant to this agreement shall be those of
          the beneficiaries and they shall be credited to them pro rata to
          their entitlement to the options as particularized in list 1, and at
          the date of the end of the trust and the transfer of the shares to
          the beneficiaries, the Trustee and the Company shall act to allot the

<PAGE>   4
                                      -4-

     4.3  If rights in respect of the options are distributed at the end of the
          trust, the Trustee shall give prior written notice thereof to the
          beneficiaries in sufficient time to receive their response and it
          shall act in accordance with the beneficiaries' instructions. If the
          beneficiaries wish to register the rights and they transfer the
          amount required therefor to the Trustee, it shall purchase the rights
          on their behalf or on behalf of some of them and they shall be added
          to their rights at the end of the trust. If the beneficiaries do not
          give notice or if the beneficiaries do not reply to the Trustee at
          the time prescribed therefor, the Trustee shall deem the
          beneficiaries who did not reply or who did not pay the fixed
          consideration on due date as having waived the offered rights.

     4.4  The Trustee shall act in its exclusive discretion regarding all the
          other subjects or rights conferred pursuant to the options or the
          shares upon exercise of the options. However, if the Trustee receives
          rights or monies in respect of the options, save for bonus shares, it
          shall transfer them to the beneficiaries pursuant to list 1 and their
          proportionate part therein.

6. THE OPTIONS

   The employee participating in this agreement, the trust and the option
   entitlement arrangement is hereby granted and given options upon the terms
   and conditions and at the times set forth below:

   6.1 A conditional and suspensory right upon the cumulative fulfillment of
       the terms and conditions particularized below to receive by way of an
       actual allotment at the end of the option term ordinary "A" shares of
       the Company, as a right to benefit from the trust arrangement at the
       time of participating in the agreement until the end of the trust term,
       and during the course whereof the Participating Employee is granted the
       right that his name shall be registered in list 1 together with a
       notation of the option for the specific number of shares specified above.

   6.2 The terms and conditions:

       The Participating Employee's right to convert the options held on trust
       on his behalf by the Trustee into shares that shall be actually allotted
       in his name is conditional and suspensory upon the fulfillment of all
       the following terms and conditions:

       6.2.1 After actual period of employment with the Company of at least 12
             months from the participation date shall confer the right to
             convert 1/4 (a fourth) of the number of shares specified in the
             option into shares that shall be actually allotted.

<PAGE>   6
                                      -6-

            6.2.2 Every month of continuous and cumulative period of work
                  thereafter shall confer the right to convert a further 1/36
                  of the total number of shares specified in the option into
                  shares that shall be actually allotted.

            6.2.3 After a continuous and cumulative actual period of work of 48
                  months, the beneficiary will have the right to convert the
                  total number of shares specified in the option into shares
                  that shall be actually allotted. The validity of the trust in
                  relation to him shall expire.

            6.2.4 The exercise of the right to an actual allotment is further
                  conditional and suspensory upon the payment of $0.35
                  (thirty-five cents) per share.

            (The periods specified in this clause above are hereinafter
            referred to as "the entitling period").

      6.3   If the employee ceases to be an actual employee of the Company at
            any stage whatsoever until the conversion of the options or part
            thereof into shares and prior to the actual allotment of shares,
            regardless of the reason for the termination of employment with the
            Company, his right to an allotment of shares or to exercise the
            balance of the allotment pursuant to this agreement shall after 60
            days of termination expire, be cancelled and nullified
            automatically and the trust in respect of such employee shall
            expire.

      6.4   If the options are cancelled because the terms and conditions of
            this clause have not been fulfilled, the employee shall not be
            entitled to consideration, refund of a payment or compensation or
            indemnity whatsoever in respect of the cancellation.

7.    The Beneficiaries' Liability

      7.1   The beneficiaries acknowledge that the Trustee is likely to hold
            non-paid up options on their behalf, whether as options upon the
            terms and conditions of this agreement or for additional rights as
            specified in clause 4 above, and if there shall be a demand for
            payment in respect of the conversion of the options into shares or
            other rights given for payment, the beneficiaries shall pay the
            amounts required immediately upon receiving the Trustee's demand
            therefor.

            Failure to comply with the demand as aforesaid is likely to lead
            to the same results as if the beneficiaries had ceased to work for
            the Company.

      7.2   Every liability and every amount that a holder of the options is
            under a duty to pay and all the obligations applicable pursuant to
            the Companies Ordinance and the Company's documents of incorporation
            to a holder of options or shares or a member of the Company, shall
            be passed on from the Trustee to the beneficiaries

<PAGE>   7
                                      -7-

            pursuant to the rate of the options or the shares held by the
            Trustee for the benefit of the beneficiaries.

      7.3   The beneficiaries hereby confirm that they acknowledge that if
            payment demands of them are not complied with, the Company may
            forfeit the options held on their behalf by the Trustee pursuant to
            the Company's articles of association and the results of the
            forfeiture shall apply to each beneficiary in accordance with the
            option for shares held on trust on his behalf by the Trustee.

      7.4   If the Trustee receives demands, requests, notices and claims,
            including payment calls, demands for payments at the time of the
            Company's winding up, notices in respect of forfeiting the options
            or any other demand, the Trustee shall, immediately upon the
            receipt thereof, send them to each of the beneficiaries in respect
            of whose options held on his behalf by the Trustee the said demands
            were received, to the beneficiary's address as appearing in his
            participation notice or to another address which the beneficiary
            sent the Trustee, provided that they shall be sent in writing and
            the liability deriving from the said demands shall apply to the
            beneficiary alone.

      7.5   The beneficiaries' liability pursuant to this clause shall apply in
            accordance with the options held on their behalf. If any charge or
            payment demand whatsoever shall relate to options held for a
            number of beneficiaries, each beneficiary shall be liable for the
            charge or the payment demand pro rata to the options held on his
            behalf.

8.    Termination of the Trust

      8.1   If the Trustee holds options for any beneficiary, including his
            successors and assigns, during the entitling period, the shares
            shall be transferred to the beneficiary's possession either on its
            own initiative or on the beneficiary's initiative, upon the
            following terms and conditions:

            8.1.1 The Company has given notice to the Trustee that an employee
                  engaged by it continuously throughout the entitling period
                  continues to be employed by it and has requested to exercise
                  the option and has paid the option monies to the Company.

<PAGE>   8
                                      8 -

          8.2  If a Participating Employee ceases working for the Company at any
               time whatsoever and for any reason whatsoever, the trust for him
               shall expire at the time of the termination of employee-employer
               relations. The expiry of the trust at the time of the termination
               of the employer-employee relations shall be pro rata to the
               balance of the beneficiary's right at such time.

     8.3  If a Participating Employee exercises a right as a beneficiary by way
          of exercising the conversion of an option into a share that shall be
          actually allotted, subject to all the terms and conditions of this
          agreement, the trust shall expire in respect of the part of the option
          converted and actually allotted at such time.

9.   ISSUE TO THE PUBLIC

     9.1  If the Company notifies the Trustee that for the purposes of an issue
          of shares to the public an undertaking by the beneficiary option
          holders is required, pursuant whereto they undertake a restriction on
          the transfer of the shares of which they are beneficiaries or to which
          they are entitled pursuant to the options or the trading of such
          shares, the Trustee shall be entitled to assume the undertaking as
          aforesaid, provided that such an undertaking shall not prevent it
          transferring options to the beneficiaries, subject to the
          beneficiaries assuming the said undertaking.

     9.2  If as a condition for the issue of shares to the public the option
          holders shall be required to undertake not to sell them during a
          specific period (hereinafter referred to as "the restriction period"),
          the Company is entitled to make demand of the Trustee to join in
          giving an undertaking as aforesaid, and in the event of a demand as
          aforesaid the Trustee shall accede thereto, even if the entitling
          period, or part thereof, mentioned in clause 6 above, has not yet
          terminated, and in such case the trust period shall be extended by the
          restriction period and the beneficiaries shall have no complaint in
          consequence thereof.

     9.3  The beneficiaries are aware that the Company is considering an issue
          to the public with the intention of listing the Company's shares for
          trading on a stock exchange either in Israel or abroad. The
          beneficiaries empower the Trustee to sign any document which, in the
          opinion of the Company's board of directors, is required to enable an
          issue as aforesaid, including changes to the Company's documents of
          incorporation and including changes in its capital structure for so
          long as the changes shall not result in the shares the subject of the
          options held on trust by the Trustee having inferior rights (save for
          voting rights) compared with the rights which other shares of the

10.   NON-TRANSFERABILITY

      The rights to the options pursuant to this agreement and the shares that
      shall be allotted to the Participating Employee pursuant thereto and upon

      The beneficiaries' rights may not be transferred to assigned in any
      manner whatsoever, including by way of pledge, charge, attachment,
      assignment and the like.

      Without derogating from the aforegoing, rights to options may only be
      transferred by way of implementing a will of an employee or his
      inheritance.

11.   REPLACEMENT TRUSTEE

      If the Trustee is unable to perform its duties or does not wish to
      perform its duties, the Company is entitled to appoint a replacement
      trustee and in such event the Trustee shall transfer the options it is

      replace the Trustee for all intents and purposes.

12.   THE COMPANY'S OTHER SHARES

      12.1  The provisions of this agreement do not prejudice the rights of

      12.2  The parties are aware that additional employees of the Company own
            rights in shares or to receive shares in other arrangements, and it
            is hereby expressly agreed that this agreement does not apply to
            and does not affect or howsoever impair rights of other
            shareholders of the Company or persons entitled to shares of the
            Company, including entitled employees as aforesaid.

13.   PAYMENT AND INDEMNITY

      13.1  An action by the Trustee and any outcome of an action by the
            Trustee, directly or indirectly, shall not render the Trustee
            liable for any payment whatsoever. In any event in which the
            Trustee is directly or indirectly ordered to make any payment in
            connection with its actions as trustee, the Company undertakes to
            directly effect and make the payment which shall be required, for
            so long as it is a payment relating to the trust, or to indemnify
            the Trustee for a payment as aforesaid upon demand received from
            it.

            or arbitrator in consequence of its operations as trustee, whether
            directly or indirectly, the Company shall bear the payment in its
            stead and shall effect the payment on the required date, and the
            Trustee shall not be liable to indemnify the Company for such
            payment.

      13.3  The beneficiaries and the Company release the Trustee from any
            liability for a negligent act or omission, and the Company shall
            indemnify the Trustee for any payment which it is required to pay
            in order to compensate any person or corporation for such an act of
            omission.

            The Trustee shall not be exempt from liability for an act or
            omission committed willfully or other than in good faith.

14.   GENERAL PROVISIONS

      14.1  If the law so obliges or if the Company or any of its shareholders
            so requests, the Company shall procure that the Trustee shall be

            of the options for shares held by it on trust.

      14.2  The Company shall bear the Trustee's remuneration.

      14.3  If the Company resolves to issue any of its shares in consequence
            of additional investors joining the Company or for any other
            reason, the Trustee's part of the options convertible into shares
            of the Company shall be diluted respectively and the beneficiaries'
            right shall also be diluted in accordance therewith, and the
            beneficiaries shall not have any complaint or claim in such regard.

      14.4  In a case where the beneficiaries have been actually allotted part
            of the shares at the time of a dilution as aforesaid or any other
            time thereafter, their shares shall be diluted in respect of the
            joining of investors or other shareholders, and the beneficiaries
            shall not, even as shareholders, have any complaint or demand in
            such regard.

      14.5  The Trustee is empowered to determine the terms and conditions for
            beneficiaries participating in the trust, in its discretion.

      14.6  The parties undertake to sign all the documents required to give

     14.7 If income tax or capital gains tax or any other tax applies in
          respect of the options or in respect of the allotment of the shares

          or for another reason, the tax shall be borne by the beneficiary in
          respect of the options or the shares held for his benefit by the
          Trustee. If tax as aforesaid is imposed, the Trustee shall be
          entitled to make demand of the beneficiary to pay the tax upon demand
          pursuant to this agreement or to deduct the imposed tax from the
          amounts due or that shall be due to the beneficiary, and such being
          in addition to any other remedy available to the Trustee at law. If
          the tax as aforesaid is imposed upon the Company, the Trustee shall
          be under a duty, upon the Company's demand, to deduct the said tax
          and to remit the amount collected to the Company, as the case may be.

          The beneficiary authorizes and empowers the Company and the Trustee
          to deduct or collect tax as aforesaid.
