        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

                hereof, 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

                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


<PAGE>   5
                proportionate share of the options pursuant to List "1".

                other regulations applying to the subject matter of this

                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.

        7.3     If the Trustee receives demands, requests, notices and claims,

8.      TERMINATION OF THE TRUST

        8.1     If the Trustee holds options or shares for any beneficiary,
                including his successors and assigns, during the Vesting Period
                that shall not be less than two years, the shares or options

                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

                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.

        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


<PAGE>   9
                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 from 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 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


<PAGE>   10

        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 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.


<PAGE>   11
        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.

        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.
