         Lessee's pro rata share of the public areas serving or which may serve
         all or a specific part of the occupiers of the Building, or public
         areas serving or which may serve all or a specific part of the

          provision of services to all occupiers of the Park (such as machinery
          rooms, transformer, electricity, communication, refuse, etc.).

          undertakes to accept possession of the aforesaid areas immediately
          upon receipt of a notice from the Company as to the completion of the
          construction thereof. For the avoidance of doubt, it is hereby
          stipulated that the Lessee shall not be liable for the payment of
          rental under this Agreement with respect to the area comprised within
          the Option prior to the delivery to it of possession as set forth
          above.

          retain the right to give notice from time to time to the Lessee, in

          on the second floor of the Building have been let or sold and only the
          last area of 500 square meters remains on the second floor of the
          Building, then the right of refusal shall apply to such last area of
          500 square meters on the second floor of the Building, and it is
          understood that the right of transfer of such area as set out above
          shall not be available to the Company.

          aforesaid is available to the Lessee with respect to 500 square meters
          on the second floor of the Building (during the course of the period
          of the aforesaid right), the Company, and it alone, shall have the
          right and sole discretion to give notice to the Lessee as to the
          transfer of such right to an alternative area on the second floor of
          the Building as set forth above, and the Lessee shall in relation
          thereto not have any claim, demand or right against the Company and/or
          any third party. It is further clarified for the avoidance of doubt

          were offered to the Lessee, and which were accepted by it for the
          purpose of the exercise of a right of first refusal, shall be

          Premises that the condition of the Premises is not, in its opinion, in
          conformity with the Technical Specification, the Supervisor shall
          investigate its claims within 7 days and should it be found that there
          is substance in such claims, or in any part thereof, the Company shall
          attend to the remedy thereof as soon as possible. It is agreed that
          repairs and/or non conformities with the Technical Specification which
          are not sufficient to prevent the reasonable use of the Premises by
          the Lessee, and which have been indicated in the protocol of the
          inspection of the Premises, shall not constitute grounds for the
          postponement of the Delivery Date.

                                       20


    11.12 As soon as may be after the date of the inspection of the Premises
          and at such time as is prescribed under paragraph 11.3 above, the
          Lessee shall accept possession of the Premises. The receipt of the
          keys of the Premises by the Lessee and its signature of the protocol
          of the delivery of the Premises shall constitute proof that the Lessee
          has received the Premises finished and completed in accordance with
          this Agreement and that save for those matters itemised in the
          protocol of the inspection of the Premises, if any, and that it has no
          claim or demand against the Company in connection therewith.

12.  Postponement of the Delivery Date
     ---------------------------------

    12.1  Should as a result of factors which are not dependant on the Company
          or over which the Company has no control or should as a result of
          force majeure, any interruption in construction take place, or should
          there be any delay in the completion of the Premises, the date on
          which the Company is obliged to complete the construction of the
          Premises shall be postponed for the period of time reasonably
          necessitated by such interruption or delay as aforesaid, provided that
          the Company shall have taken reasonable steps in good time in order to
          prevent or reduce the delay in the delivery of the Premises as a
          result of one of the foregoing causes, including consultation with the
          Lessee's representative.

          For the avoidance of doubt, it is hereby expressly declared that any
          extension determined under this paragraph shall not entitle the Lessee
          to any rebate in rental or to the payment of compensation and/or any
          expenses whatsoever. However, should the aforesaid interruption and/or
          delay continue for 6 months, the Lessee shall be entitled to be
          released from its obligations under this Agreement, on dispatch of 30
          days advance written notice of cancellation. Should the Lessee cancel
          this Agreement in pursuant to this sub-paragraph 12.1 and in the
          circumstances described in this sub-paragraph, the parties shall
          relinquish the contractual arrangements between them without either
          party having any claim, cause of action, demand or such like against
          the other in connection with the cancellation of the Agreement.

    12.2  Notwithstanding any provisions contained in this Agreement, a delay in
<PAGE>

                                       21


          the completion of the Premises and delivery thereof to the Lessee not
          exceeding 14 days, as well as any delay arising from the causes
          enumerated in paragraph 12.1 above, shall not constitute a breach of
          the Company's obligations under this Agreement and shall not entitle
          the Lessee to any remedy whatsoever.

    12.3  Any delay in effecting delivery other than in pursuance of paragraphs
          12.1 and/or 12.2 above shall entitle the Lessee to agreed compensation
          of $ 650 for each day of delay.

    12.4  It is hereby agreed and recorded that the Delivery Date of possession
          of the Premises to the Lessee as set forth in paragraph 11.1 above  is
          determined by the parties having regard to and on the basis of the
          Technical Specification and of the works involved in the completion of
          the Premises in accordance therewith. Accordingly, in any instance of
          substantial changes to be made to the Technical Specification at any
          time after signature of this Agreement, the Delivery Date shall be
          postponed for a period of time reasonably necessitated by such changes
          to the Technical Specification.

          For the avoidance of doubt it is clarified that changes to the
          Technical Specification may be made only at the request of the Lessee
          on prior written notice to the Company and with its approval.



                       Third Section - the Consideration
                       ---------------------------------

13. The Basic Rental
    ----------------

    The parties hereby agree as follows :

    13.1  The rental payable by the Lessee to the Company shall be an amount in
          new Israeli shekels equivalent to $ 13.30 (thirteen United States
          dollars and thirty cents) per month for each square meter of the Area
          of the Premises, in accordance with the manner of computation of the
          area thereof as set forth above (hereinafter : "the Rental Fee").

          The Lessee shall be entitled to give written notice to the Company, by
          _________ as to its wish to subtract certain items from those
<PAGE>

                                       22

          components of the Technical Specification which are in addition to and
          beyond the standard specification as applied by the Company and which
          had been included in the Technical Specification by agreement between
          the parties, by detailing the number of the subtracted items
          (hereinafter : "the Subtraction from the Technical Specification"),
          provided that the subtraction of these items from the Technical
          Specification is feasible from a technical - implementation aspect,
          and does not prejudice the normal course of completion of the
          Premises.

          Should the Lessee give notice of its wish to subtract from the
          Technical Specification as aforesaid, the Company's Engineer shall
          determine, in consultation with the Lessee's architect the monetary
          value of the aforesaid subtraction. Should the Company's Engineer and
          the Lessee's architect fail to reach agreement as regards the monetary
          value of the aforesaid subtraction within 14 days from the date of
          notification by the Lessee as to its wish to subtract from the
          Technical Specification, the parties shall appoint an referee by
          consensus who shall adjudicate within 7 days of referral by either
          party on the monetary value of the aforesaid subtraction.

          Should items to the overall value of $10,000 (ten thousand United
          States dollars) be subtracted from the Technical Specification, the
          Rental Fee shall be reduced by an amount in new Israeli shekels equal
          to $0.04 (four United States cents) for every square metre of the Area
          of the Premises. For example, should items to the overall value of
          $20,000 (twenty thousand United States dollars) be subtracted from the
          Technical Specification, the Rental Fee payable by the Lessee to the
          Company shall be an amount in new Israel shekels equal to $13.22
          (thirteen United States dollars and twenty two cents) per month for
          every square metre of the Area of the Premises, in accordance with the
          manner of computation of the Area thereof as set forth above.

          The Rental Fee shall be paid by the Lessee to the Company in its
          shekel value in accordance with the representative rate of exchange of
          the United States dollar on the date of signature of this Agreement
          together with differentials linked to the Index as set forth hereunder
          with effect from the date of signature of this Agreement to the actual
          date of effecting each of the Rental Fee payments.

          The component of the differentials linked to the Index comprised
          within the Rental Fee as aforesaid, shall be computed in accordance
          with the following definitions :
<PAGE>

                                       23

          --------------          standing at 163.9497 points.

          The New Index :         The latest Index as published from time to
          -------------           time prior to the date prescribed in this

          ---------------------   Base Index, divided by the Base Index and
                                  multiplied by the Rental Fee at the above
                                  rate.

    13.2  Should the Lessee exercise its right as set forth in paragraph 7.2
          above to extend the Lease Period for the First Additional Lease
          Period, a Rental Fee 7% higher than the last Rental Fee payable during

          Period, and all the remaining conditions set out above shall apply in
          connection therewith, mutatis mutandis.

          conferring on the Lessee any right to continue to keep such movable
          property there, nor as precluding the Company from taking any

               The foregoing insurance shall be extended in order to indemnify
               the Company should it be regarded as the employer of the Lessee's
               employees or any of them.

          (d)  Loss of Revenue Insurance (save for Rental Fees), to the full
               value thereof in regard to the Lessee, by reason of damage caused
               to the Premises or destruction thereof as a result of the risks
               insured under paragraph (a) of this sub-paragraph, for an
               indemnity period of not less than 12 months. The foregoing
               insurance shall include a waiver of the right of subrogation vis
               a vis the Company and other lessees in the structure and the
               Park, under whose insurance a corresponding clause is included
               with respect to a waiver of the right of subrogation vis a vis
               the Lessee, provided that the foregoing provisions regarding the
               waiver of the right of subrogation shall not apply in favour of a
               person who had caused damage with wilful intent.

     35.2 Should the Lessee be of the opinion that it is necessary to effect
          insurance supplementary and/or additional to the Lessee's insurance
          set forth above, the Lessee hereby undertakes to effect and to
          maintain such supplementary and/or additional insurance, insofar as
          required.

          In any additional and/or supplementary insurance as aforesaid, a
          clause shall be included as to the waiver of the right of subrogation
          vis a vis the Company and all persons acting on its behalf (with
          respect to Property Insurance), and/or the insurance shall be extended
          to include the Company as an additional insured under the policy,
          subject to a cross liability clause (with respect to Third Party
          Liability Insurance).

     35.3 The Lessee's insurance shall include an express condition whereby it
<PAGE>

                                       39

          takes precedence over any insurance effected by the Company, and the
          insurer waives any provision regarding participation by the Company's
          insurance. In addition the Lessee's insurance shall include an express
          condition whereby it shall not be cancelled nor reduced nor lapsed
          unless 60 days advance notice thereof shall have been given to the
          Company by registered post.

     35.4 The Lessee shall furnish the Company with confirmation, on the date of
          acceptance of possession of the Premises, as to the Lessee's insurance
          having been effected, signed by the insurer.

          Should at any time the Lessee's insurer notify the Company that the
          Lessee's insurance is about to be reduced, cancelled or lapsed, as set
          out in paragraph 35.3 above, the Lessee shall be obliged to effect the
          Lessee's insurance anew and to furnish confirmation of having so
          effected insurance anew, 14 days prior to the date of such reduction
          or cancellation or lapsing as aforesaid.

          It is hereby expressly agreed that furnishing confirmation of the
          Lessee's insurance having been effected and examination thereof by the
          Company shall in no manner be construed as imposing any responsibility
          whatsoever on the Company and/or on any person on its behalf in
          relation to such insurance, the accuracy thereof and/or its conformity
          with the provisions of this Agreement, and the Lessee hereby releases
          the Company and/or all persons on its behalf from any liability as
          aforesaid.

     35.5 The Lessee hereby undertakes to comply with the conditions of the
          insurance policies, to revise the insured amount with respect to the
          insurance effected under paragraphs (a) and (d) of sub-paragraph 35.1
          above, to pay the insurance premium in its entirety and on the due
          date thereof and to ensure that such insurance is renewed from time to
          time as required, in order that the same shall remain in force for the
          whole of the Lease Period.

     35.6 Should the Lessee fail to effect and/or maintain the insurance or any
          part
<PAGE>

                                       40

          thereof referred to in this paragraph, the Company shall be entitled -
          but not obliged - to effect and/or maintain such insurance at the
          Lessee's cost, and the Lessee shall be obliged to refund to the
          Company any sum of money expended for such purpose together with
          linkage differentials and interest at the rate specified in sub-
          paragraph 46.1 or with interest at the rate specified in sub-paragraph
          46.2 hereunder, at the Company's election, where the linkage
          differentials and interest, or interest alone, is reckoned from the
          date of disbursement of such monies by the Company to the actual date
          of refund thereof.

     35.7 The Lessee declares that it shall have no claim and/or demand and/or
          action against the Company and persons acting on its behalf arising
          from damage against which it is entitled to indemnification or against
          which it would have been so entitled but for the excess specified in
          the policy under the insurance to be effected as set forth above, and
          it hereby releases those persons set forth at the head of this sub-
          paragraph from any liability for damage as aforesaid.

          The provisions of this paragraph shall not apply in the event of
          damage as set out in this sub-paragraph caused as a direct result of
          the Company's gross negligence, provided that the Company had received
          written warning to the effect that failure to remedy its gross
          negligence as aforesaid would result in the insurance company not
          giving effect to the indemnity.

     35.8 It is recorded that effecting the insurance by the Lessee as set forth
          above shall in no manner be construed as reducing or detracting in any
          form whatsoever from the Lessee's obligations under the Lease
          Agreement and Management Agreement, or as releasing it from its
          obligation to compensate the Company and/or the Management Company
          and/or any person whatsoever arising from any damage caused either
          directly or indirectly for which it is responsible. The actual payment
          of any particular insurance benefits shall not be construed other than
          as reducing the amount of the indemnity and/or compensation to which
          the Company and/or the Management Company is entitled arising from
          damage or loss.

     35.9 The provisions contained in this section shall only add to (not
          derogate from) any other provision of the Lease Agreement or
          Management Agreement relating to the release of the Company and/or the
          Management Company from liability.

     The Company's Insurance
     -----------------------

     35.10 Without derogating from the Company's liability, whether by law or
           under the provisions of this Agreement, the Company and/or the
           Management Company hereby undertakes to arrange and to maintain, at
           its cost and for the entire Lease Period, the insurance set forth
           hereunder (hereinafter collectively called "the Company's Insurance")
           with an insurance company duly authorised by law, namely:

           (a) Insurance of the structure of the Premises against loss or damage
               capable of being caused as a result of fire, smoke, lightning,
               explosions, earthquake, storm and gale, flooding, damage through
               liquids and burst pipes, impact by aircraft, accident impact,
               riots, strikes, malicious damage, break-in and robbery.

               The aforesaid insurance shall include a waiver of the right of
               subrogation (indemnification) vis a vis the Lessee and all
               persons acting on its behalf arising from any damage caused by
               them, provided that the foregoing provisions regarding the waiver
               of the right of subrogation shall not apply in favour of a person
               who had caused damage with wilful intent. For the purposes of
               this paragraph, "Structure of the Premises" includes all the
               systems constituting an integral part of the structure and
               expressly does not include the contents of the Premises as
               indicated in paragraph 35.1 (a) above, as well as any Addition
               and/or improvement and/or expansion effected to the Premises by
               or on behalf of the Lessee.

           (b) Third party liability insurance insuring the liability of the
               Company and/or the Management Company under any law and/or of the
               Lessee arising from bodily injury or damage capable of being
               caused to the person within the public areas, not constituting
               part of the areas let to the Lessee under this Agreement, with a
               limit of liability of not less than $ 2,500,000 (two and a half
               million United States dollars) per occurrence and per annual
               insurance period. The Insurance shall be subject to a special
               extension by which the Lessee shall be included as an additional
               insured with respect to its liability for an insurance occurrence
               within the public areas in the structure of the Premises outside
               the Area of the Premises, and shall be subject to a cross
               liability clause whereby the insurance shall be deemed to have
               been separately effected on behalf of each individual insured.
               For the purpose of this extension an express condition shall be
               added
<PAGE>

                                       42

               to the insurance whereby the cover under the policy with respect
               to the public areas takes precedence over any insurance effected
               by the Lessee and that the insurer waives any claim and/or demand
               regarding participation by the Lessee's insurance.

           (c) Employer's liability insurance arising from the Company's
               liability towards its employees and any person acting on its
               behalf with such standard limit of liability as is applied in
               Israel at the time of effecting the insurance and/or the renewal
               thereof. Such insurance shall not be subject to any limitation
               whatsoever as to hours of work, working at heights or at depths,
               contractors, sub-contractors and their employees, bait, poisons
               as well as the engagement of juveniles.

               The aforesaid insurance shall be extended in order to indemnity
               the Lessee should it be regarded as the employer of the Company's
               employees or any of them.

           (d) Insurance covering loss of revenue from rental and management fee
               expenses to the full value thereof, by reason of damage caused to
               the Premises in such manner as does not permit of the Lessee's
               activity therein, or by reason of destruction thereof as a result
               of the risks insured under paragraph (a) of this sub-paragraph,
               for an indemnity period of not less than 12 months. The foregoing
               insurance shall include a waiver of the right of subrogation
               (indemnification) vis a vis the Lessee and/or any person on its
               behalf, provided that the foregoing provisions regarding the
               waiver of the right of subrogation shall not apply in favour of a
               person who had caused damage with wilful intent.

     35.11 The Lessee undertakes to utilise the monies which it receives from
           the insurance company under the policies only for the purpose of the
           immediate reconstruction of the damage and/or the policies. The
           foregoing shall not in any manner be construed as limiting or
           derogating from the Company's right to exercise its rights under the
           policies.

                 Seventh Section - Maintenance of the Premises
                 ---------------------------------------------

36.  Maintenance of the Premises and Repairs
     ---------------------------------------

     36.1 The Lessee shall be liable for the proper maintenance of the Premises
          and shall repair at its expense any defect and/or fault and/or damage
          caused to the Premises, whether by the Lessee or by others, whether by
          reason of wear and tear or for any other reason, save for repairs
          expressly applicable to the Company.

     36.2 The Lessee shall not be obliged to repair damage to the Premises
          resulting from defects in the construction of the Premises, arising
          from reasonable wear and tear, from acts of war, an earthquake or from
          any other unforeseen act of nature, or repairs due by a contractor in
          pursuance of the Sale (Apartments) - Maintenance Period Law (even
          though the aforesaid Law does not apply to this Agreement and/or to
          the relationship of the parties thereunder).

          The Company shall repair any damage caused to the Premises as set
          forth in this paragraph within a reasonable time and subject to the
          provisions of sub-paragraph 36.5 hereunder and upon receipt of the
          insurance benefits as set forth in paragraph 35 of this Agreement.
          Should urgent repairs be required, the Lessee shall be entitled but
          not obliged to repair the same at its cost and the Company shall
          compensate it therefor on first demand by the Lessee and subject to
          the cost of repair being reasonable. Notwithstanding the foregoing,
          the Company shall repair damage to the Premises for which a contractor
          is responsible under the Sale (Apartments) - Maintenance Period Law,
          unrelated to the receipt of insurance benefits.

     36.3 Notwithstanding the foregoing, should any damage whatsoever be
          occasioned to the Premises and/or the Building such that, in the
          opinion of the Company and/or the Lessee the it is not possible for
          the Lessee to continue to use the Premises, the Company shall be
          entitled, in its sole and absolute discretion, to determine whether or
          not to rebuild the Premises and reinstate the same to such a condition
          as would enable their continued use. Should the Company decide not to
          rebuild the Premises, the parties to this Agreement shall be released
          from their obligations thereunder without any compensation.

     36.4 If the aforesaid damage is classed as a "total loss" in relation to
          the Premises only, the Company shall rebuild the Premises should
          liability for the damage be imposed on the Company. Should the damage
          be to
<PAGE>

                                       44

          the Area of the Premises alone, the provisions of paragraph 36.3 above
          shall apply.

     36.5 The Lessee shall give notice to the Company as to any damage caused to
          the Premises as set forth in sub-paragraph 36.2 above, within three
          business days from the time of discovery thereof. Should the Lessee
          fail to give notice as aforesaid, the Lessee shall bear any further
          expense occasioned to the Company as a result of the failure to give
          notice as aforesaid and on time.

     36.6 The Company and/or the Management Company shall be entitled to prepare
          management rules for the Park. The Lessee undertakes to observe such
          management rules which shall constitute Annex D to this Agreement,
                                                  -------
          subject to the provisions of such rules not obliging the Lessee to pay
          any monies beyond those prescribed in this Agreement and in the
          Management Agreement, and subject to the provisions of the rules not
          prejudicing the Lessee's capability to make on-going use of the
          Premises.

37.  Prohibitions
     ------------

     For the avoidance of doubt it is hereby expressly clarified :

     37.1 Subject to the provisions of paragraph 36.2 above, the Lessee shall
          not be entitled to attend to the air conditioning installations on the
          Premises, the maintenance and/or repair thereof and/or to carry out
          any act whatsoever thereon and/or to enable other persons (even though
          they may be professionals and air conditioning specialists) to
          undertake any of the foregoing in regard to the air conditioners on
          the Premises.

     37.2 Should the Lessee breach the provisions of sub-paragraph 37.1 above
          and as a result thereof any damage be occasioned to the air
          conditioning installations, the Lessee shall bear the full cost of the
          repair of such damage together with linkage differentials as specified
          and interest at the rate specified in sub-paragraph 46.1, or together
          with interest at the rate specified in sub-paragraph 46.2, at the
          Company's election, and it shall be liable for the payment of an air
          conditioning charge even though the supply of air conditioning to the
          Premises may be discontinued for any period whatsoever.

          A lessee leasing the Premises which, or a part of which, are not air
          conditioned, shall not itself be entitled to be connected in any form
          whatsoever to the air conditioning system. Any such aforesaid
<PAGE>

                                       45

          connection may be undertaken only by the Company.

          Any connection by a lessee to the air conditioning other than through
          the Company, either for the purpose of receiving air conditioning
          services or for any other purpose, shall be regarded as a fundamental
          breach of the provisions of this Agreement and shall entitle the
          Company to any relief accorded to it as a result of the aforesaid
          breach pursuant to this Agreement and under any law.


                     Eighth Section - the Company's Rights
                     -------------------------------------

38.  Entry onto the Premises
     -----------------------

     Employees of the Company and its agents shall be entitled to enter upon the
     Premises at any time during ordinary working hours and in co-ordination
     with the Lessee, for the purpose of inspection or effecting repairs and
     such other works as are, in the Company's opinion, necessary.

     In the event of an emergency, the Company and/or any person on its behalf
     shall be entitled to enter onto the Premises without having obtained the
     prior consent of the Lessee.

39.  Execution of Works on the Premises
     ----------------------------------

     39.1 It is stipulated and agreed between the parties that the Company
          and/or its representatives and/or any person acting in its name and/or
          on its behalf shall be entitled to lead through the Premises (or
          thereon) pipes, conduits and other conductors for water, sewage, gas,
          electricity, telephone and/or for any other purpose and to execute
          works and/or other installations on the Premises for the purposes of
          use by the property adjacent to the Premises, or for any other similar
          purpose provided that :

          (a)  The Company exercises the powers conferred upon it in this
               paragraph in such form and manner as not to be injurious to the
               reasonable use of the Premises and any inconvenience and/or
               disturbance occasioned to the Lessee is reduced as much as
               possible.

          (b)  The Company carries out in those parts of the Premises - as well
               as in installations carried out by the Lessee with the Company's
               authority - which are adversely affected by the carrying out the
<PAGE>


                                       46

               aforesaid works, any repairs which may be required to reinstate
               the Premises to their former condition.

          (c)  The Company shall co-ordinate  with the Lessee to the extent
               possible the dates on which the aforesaid works are to be carried
               out.

40.  Execution of Works in the Building and in the Park
     --------------------------------------------------

     40.1 The Lessee declares that it is aware that the establishment of the
          Park has not yet been completed and that works relating to the
          construction of additional structures in the area of the Park are
          being, and shall in the future be, undertaken, and it hereby expressly
          waives any claim of inconvenience likely to be caused to it as a
          result of noise, waste and such like associated with the execution of
          the aforesaid works, subject to the Company doing whatever it can in
          order that the execution of the foregoing works does not unreasonably
          prejudice the Lessee's potential to use the Premises.

     40.2 The Company shall be entitled, in its sole discretion, to effect any
          addition to the construction areas of the Land, to the extent that the
          urban building scheme which is, and/or which shall become, applicable
          to the Land shall enable this, without the need for prior notice
          thereof to be given to the Lessee or to obtain the Lessee's consent
          thereto and without the Lessee preventing and/or interfering with
          and/or opposing such addition to the aforesaid construction areas by
          the Company.

     40.3 The Lessee declares and undertakes that it shall not in any manner
          whatsoever, either directly or indirectly, prevent nor lodge any
          objection to any plan submitted by the Company for any addition to the
          construction areas on the Land and/or in the Building, whether an
          urban building scheme or a plan for building permits or any other
          plan, provided that no construction in the Building (as distinct from
          any construction in the Park and/or in any part thereof), under any
          such aforesaid plan, shall be carried out during the Lease Period.

     40.4 The Lessee undertakes to remove at its cost any obstacle and/or object
          and/or installation and/or the construction of any additional areas
          accessory belonging and situate in any place intended for  by the

          it, that the Company shall be entitled to prescribe such traffic and
          parking arrangements in the Park as it shall see fit, to levy, with
          effect from such date as shall be determined by it, a payment for

          possible that a one-off payment may also be prescribed for the
          purchase of a "smart card" which would enable ingress to the parking
          area and egress therefrom), in the parking lots and in the parking
          areas linked to the structures, all in such amounts and on such

          and/or the right to impose fines on the owner of the vehicle and/or
          the right to take such other steps as shall be published.

42.  Obligation to Furnish
     ---------------------

     As security for the performance by the Lessee of all the provisions of this
     Agreement in their entirety and on the due dates thereof, and without
     derogating from the generality of the foregoing, as security for the
     payment of the Rental Fees and the other amounts for which the Lessee is
     liable under this Agreement, the Lessee hereby undertakes to furnish the
     collateral set forth hereunder in this section.

43.  Bank Guarantee
     --------------

     43.1 The Lessee hereby undertakes to deposit an autonomous unconditional
          and linked bank guarantee with the Company in an amount equal to the
          rental for the Premises, for the parking and for maintenance charges
          (as set out in paragraph 4 of the Management Agreement Annex B) for 3
          months of the lease together with value added tax as applicable,
          operative for a period of 14 months and renewable from time to time
          with effect from the date of delivery thereof and until 60 days shall
          have elapsed from the date of termination of the lease under this
          Agreement  (hereinafter: "the Guarantee").

          The Guarantee shall be in the form attached to this Agreement as Annex
                                                                           -----
          E.
          -

     43.2 The Lessee shall deposit the letter of Guarantee with the Company by
          not later than 8th June 1999. Until the date of furnishing the
          Guarantee as set out in this sub-paragraph, the Company shall be
          entitled, at its sole discretion, not to carry out any act and/or
          obligation of any nature under this Agreement involving the
          disbursement of monies. The non-performance of acts and/or obligations
          as aforesaid, shall not be regarded in any circumstances as a breach
          of the Company's obligations. Upon furnishing the Guarantee by due
          date as aforesaid, the Company's obligation to carry out acts and
          obligations as aforesaid shall have been perfected. Until the
          furnishing of the aforesaid letter of Guarantee to the Company, a
          promissory note signed by the Lessee, shall serve as collateral, which
          the Lessee shall deposit with the Company on the date of signature of
          this Agreement in the sum of
<PAGE>

                                       49

          NIS 395,000. The provisions pertaining to the aforesaid promissory
          note and the form thereof are set forth in Annex F to this Agreement
          and in Schedule 1 to the aforesaid Annex F. The promissory note shall
                 ----------                  -------
          be returned to the Lessee against receipt by the Company of the
          aforesaid Guarantee. It is recorded that the furnishing of the
          promissory note shall not in any manner be construed as derogating
          from the Lessee's liability to put up the aforesaid Guarantee on the
          date set out in this sub-paragraph by fulfilment of all the provisions
          of the Agreement pertaining thereto.

     43.3 Should the Lessee fail to pay rental and/or any other amount for which
          it is liable under the provisions of this Agreement and/or those of
          the Management Agreement on the due date, and/or fail to fulfil any of
          its obligations towards the Company under the provisions of this
          Agreement or the Management Agreement, the Company shall be entitled -
          but not obliged and after 14 days prior written notice thereof shall
          have been given to the Lessee - to realise and recover from the amount
          of the Guarantee, the amount unpaid on the due date thereof and/or any
          other amount owed by the Lessee at such time to the Company (together
          with linkage and interest due to it with respect thereto) as well as
          to take proceedings against the Lessee arising from the breach of this
          Agreement and/or the Management Agreement, or not to take proceedings
          as aforesaid, without derogating from the rights available to the
          Company under any law against the Lessee.

     43.4 The Lessee hereby declares and agrees that without derogating from the
          aforesaid Guarantee, the full validity of the Guarantee shall not be
          attacked, including the Company's right to realise the same, in its
          entirety or in part, by reason of any claim or right available to the
          Lessee under the provisions of this Agreement, since the collateral is
          final, decisive and absolutely autonomous, not capable of alteration,
          of being made conditional, of being set off, mortgaged, attached or
          seized, for any reason whatsoever.

          In addition the realisation of the Guarantee by the Company as
          aforesaid shall not confer on the Lessee any right whatsoever in and
          to the Premises and shall not amount to a waiver or to its being
          conditional upon any of the rights of the Company or of the
          obligations of the Lessee under the provisions of this Agreement, nor
          shall it replace any of the same.

     43.5 Should the Company have realised the Guarantee and made use of all or
          any part of the amount of the Guarantee, in the circumstances
          described
<PAGE>

                                       50

          above, the Lessee shall be obliged to raise the Guarantee to the
          original amount thereof immediately upon receipt of the Company's
          first demand therefor, by way of the furnishing of a fresh Guarantee,
          for the period and at the amount of the original Guarantee. Should a
          new Guarantee be furnished as aforesaid, the Company shall refund to
          the Company the amount of the original Guarantee after the deduction
          of the amount which had been so utilised as aforesaid and after set
          off of the costs occasioned to the Company in connection with the
          realisation of the Guarantee.

     43.6 The Lessee shall, 45 days prior to the expiration of the validity of
          the Guarantee, furnish the Company with an original extension of the
          Guarantee, together with all the conditions thereof, duly signed by
          the bank issuing the same. Should the Lessee fail to extend the
          Guarantee as required, the Company shall be entitled to realise the
          original Guarantee and to hold the proceeds in lieu thereof.

     43.7 Prior to the commencement of the last year of the lease the Lessee
          shall deliver a Guarantee to the Company the validity of which shall
          lapse 60 days after the date of expiration of the lease, to secure the
          actual fulfilment of all the Lessee's obligations under this
          Agreement, including those covering any indebtedness of the Lessee as
          well as those relating to the termination of the lease, which includes
          those in connection with the vacating of the Premises by the Lessee at
          the expiration of the Lease Period.

          It is stipulated and agreed that the expiration of the Lease Period
          and/or the restoration of possession of the Premises to the Company
          shall in no manner be construed as a derogation of the Company's right
          to realise the Guarantee in the manner set out above in relation the
          aforesaid period of 60 days.

          Should, after realisation of the Guarantee as aforesaid, any amount
          remain out of the amount of the Guarantee held by the Company, the
          Company shall refund to the Lessee the balance of the amount of the
          Guarantee, setting off the costs occasioned to the Company in
          connection with the realisation of the Guarantee, together with
          linkage differentials as set forth in paragraph 46.1 hereunder, from
          the date of expiration of the lease to date of actual payment.

          It is stipulated and agreed that the realisation of the Guarantee as
          set forth in this sub-paragraph shall in no manner be construed as
          derogating from any claim or right of the Company against the Lessee
<PAGE>

                                       51

          pursuant to this Agreement or under any law.

     43.8 All costs and/or payments and/or commissions arising from the issue of
          the Guarantee under this paragraph shall be due by the Lessee and
          shall be paid by it.

     43.9 A breach of the provisions of this paragraph shall be regarded as a
          fundamental breach of the provisions of this Agreement.

          lawful relief, including compensation and/or a mandamus and/or an

          thereafter on account of the capital of the debt and thereafter on
          account of current payments, irrespective of whether the Lessee had
          remitted the amount on account of the debt or whether it had purported
          to effect current payments.

     46.4 It is hereby agreed between the parties that should the Lessee be in
          arrears in the payment of rental and/or in the payment of amounts
          pursuant to  the Management Agreement and/or in the payment of
          electricity consumption charges, the Company shall be entitled, in

     appointment or order not have been cancelled within 90 days, the very fact

     case may be, shall be obliged to refund to it such monies as it shall have
     expended for the purposes of the removal of such equipment, goods and
     effects, the transportation and storage thereof together with linkage
     differentials and/or interest at the rate specified in sub-paragraph 46.1
     or 46.2, at the Company's election.

     The Lessee, the receiver, pre-liquidator or liquidator, as the case may be,
     hereby release the Company from liability for any loss and/or damage which
     might be caused to such equipment, goods and/or effects during the course

                                       56

          Lessee pursuant to this Agreement or under any law, including payments
          for electricity, water, municipal rates, Bezeq and so forth, the
          Company shall give notice to the Lessee as to its intention to pay the
          aforesaid amount instead of the Lessee 14 days prior to the payment
          thereof. Should the Lessee itself fail to pay the aforesaid amounts,
          even after receipt of notice from the Company, the Company shall be
          entitled - but not obliged - itself to pay such sum as set out above.

     50.2 The Lessee shall refund to the Company any amount paid by the Company
          as aforesaid within 14 days from the date of receipt of a demand to do
          so, together with interest and linkage differentials as set forth in
          paragraph 46.1 or with interest alone as set forth in paragraph 46.2,
          in the Company's absolute discretion, from the date of dispatch of
          such notice to date of actual payment.


                       Eleventh Section - Miscellaneous
                       --------------------------------

51.  Transfer of Rights
     ------------------

     51.1 The Lessee shall not be entitled to transfer and/or to mortgage in any
          form or manner all or any part of the rights conferred upon it under
          this Agreement to any other person or persons. Any act of a
          corporation constituting the Lessee, whether a single act or a number
          of acts cumulatively, including any act as a result of which control
          is passed, directly or indirectly, from the owners of the corporation
          at the time of signature of this Agreement to any third party
          whatsoever, shall not under any circumstances and in any manner
          derogate from the obligations of the Company under this Agreement, nor
          alter in any form whatsoever the purpose of the lease and/or shall not
          constitute grounds for the alteration of any of the provisions of the
          Agreement or the manner of fulfilment of the Lessee's obligations
          hereunder.

          Notwithstanding the provisions of paragraph 51.1 above, the transfer
          of rights and the use of the Premises shall be permitted to an
          associated and/or affiliated company and/or subsidiary of the Lessee
          (hereinafter: "the Transferee Company"), provided that the Transferee
          Company enters into this Agreement as a further party or signs a
          separate agreement with the Company, along with the Lessee and under a
          reciprocal guarantee between them, and provided that the Transferee
          Company furnishes the Company with guarantees as set forth in the
          Ninth Section of this Agreement, for the fulfilment of the Agreement
          to the Company's satisfaction.
<PAGE>

                                       57

     51.2 Notwithstanding the provisions of paragraph 51.1 above, it is hereby
          agreed that the Lessee shall be entitled to permit the use of parts of
          the Premises (as distinct from the whole of the Premises) to other
          persons as sub-lessees provided that the identity of the foregoing
          sub-lessees is approved in advance and in writing by the Company, and
          subject in any event notwithstanding the permission to use as
          aforesaid, the Lessee remaining absolutely liable to the Company for
          the fulfilment of all its obligations under this Agreement in their
          entirety and on the due dates thereof, in relation to the areas in
          which the sub-lessee is permitted to operate as aforesaid. The Lessee
          and the sub-lessee shall be guarantors under a reciprocal guarantee
          inter se in relation to their obligations with respect to the
          Premises.

          It is stipulated that the Lessee shall not be entitled to let parts of
          the Premises to other persons as sub-lessees for any period in excess
          of the Lease Period under this Agreement and/or for the Additional
          Lease Period (if applicable) and/or for the Second Lease Period (if
          applicable), and nothing contained in any sub-lease made contrary to
          the foregoing shall be construed as binding the Company.

          Should the Lessee let parts of the Premises as set out in paragraph
          51.2 above, the Company shall be entitled, but not obliged, to enter
          into contractual arrangements direct with such sub-lessee by
          subtraction from the relevant Areas of the Premises of the Lessee.

     51.3 The Company shall be entitled to transfer and/or mortgage its rights
          and obligations under this Agreement  to any other person provided
          that this does not derogate from the Lessee's rights under this
          Agreement.

     51.4 It is stipulated that in any event, even though transfer is effected
          in accordance with and subject to the provisions of this paragraph,
          all the provisions of this Agreement shall continue to apply and be
          binding on the Lessee and such transfer shall in no manner be
          construed as detracting from any of its obligations towards the
          Company.

52.  Right of First Refusal
     ----------------------

     52.1 As set out above, the Company hereby grant to the Lessee a right of
          first refusal to lease from the Company the Further Area, in addition
          to the remainder of the leased areas to the Lessee under this
          Agreement. The right of first refusal shall be operative with effect
          from the date of signature of this Agreement until 3 (three) months
          shall have elapsed
<PAGE>

                                       58

          from the Date of Delivery of possession as set forth in paragraph 11.1
          above (hereinafter: "the Right of Refusal Period").

     52.2 It is hereby recorded that the right of first refusal shall apply only
          in relation to contractual arrangements wherein the Company grants
          lease rights in the Additional Area to any third party whatsoever.
          With respect to any contractual arrangements between the Company and
          any third party whatsoever for the sale of the whole or any part of
          the Further Area, no right of refusal whatsoever shall accrue to the
          Lessee.

     52.3 In regard to the aforesaid right of first refusal, the following
          provisions shall apply:

          (a)  Should the Company, in its sole discretion, make the Additional
               Area available for letting, and should it reach an agreement with
               any third party whatsoever, subject to the right of first refusal
               hereby granted to the Lessee, with respect to the letting of the
               Additional Area to such third party, the Company shall offer to
               let the Additional Area to the Lessee prior to its offer to
               conclude any transaction whatsoever with that third party, on
               conditions identical with those agreed as aforesaid with that
               third party. Should the Lessee be desirous of leasing the
               Additional Area from the Company on the foregoing conditions, the
               Lessee shall give notice thereof to the Company within 15 days
               from the date of delivery to it of the offer to let the
               Additional Area as aforesaid. In the event of the Lessee giving
               notice to the Company that it does not wish to lease the
               Additional Area on the foregoing conditions, or should no notice
               whatsoever be given to the Company, and upon the expiration of
               the 15 days as aforesaid, the Lessee shall be regarded as having
               waived its right to lease the Additional Area on the foregoing
               conditions, and in such event the Company shall be entitled to
               let the Additional Area to any third party whatsoever on
               conditions no more favourable than those under which the
               Additional Area had been offered to the Lessee.

          (b)  Should, after waiver on the part of the Lessee of its right to
               lease the Additional Area on the conditions set out in paragraph
               (a) above, the Company reach an agreement with any third party
               whatsoever, subject to the right of refusal hereby granted to the
               Lessee, as to the letting of the Additional Area to that third
               party on conditions more favourable than those offered to the
               Lessee as set forth in paragraph (a) above, the Lessee's right of
               first refusal
<PAGE>

                                       59

               shall be renewed and the Company shall be obliged to offer the
               Additional Area to the Lessee for the second time prior to its
               letting the same to that third party, on conditions identical to
               those agreed upon as set out in this paragraph (b) with that
               third party, and all the provisions set forth in paragraph (a)
               above shall apply in connection therewith.

               The Company shall enable the Lessee, at its request, to peruse
               the relevant parts of the lease agreement entered into with that
               third party in order to verify the fulfilment of the provisions
               of this paragraph.

          (c)  It is hereby recorded that upon expiration of the Right of
               Refusal Period or waiver by the Lessee of its right as set out in
               sub-paragraph (a) above, irrespective of whether the Lessee had
               given notice that it did not wish to lease the Additional Area,
               or whether it had not given any notice whatsoever to the Company,
               and upon the expiration of the period of 15 days as set out
               above, the Lessee shall have no rights in and to the Additional
               Area, nor shall it have any claim against the Company and/or
               against any third party whatsoever with whom the Company enters
               into contractual  arrangements, if so entered into.

53.  Vacating
     --------

     53.1 The Lessee shall vacate the Premises on the expiration of the Lease or
          the First Additional Lease Period or on the expiration of the Second
          Additional Lease Period, as the case may be, and shall restore  sole
          possession of the Premises to the Company free of any person or
          property not being the property of the Company.

          In the event of the Lessee being obliged to vacate the Premises in
          accordance with the conditions of this Agreement, either for the
          reason set forth in this paragraph or for any other reason set forth
          in this Agreement and/or under any law, it shall be obliged to restore
          sole possession of the Premises, together with the keys, totally
          vacant and in good condition and fit for immediate use, save for
          reasonable wear and tear.

          Furthermore the Lessee shall, on expiration of the Lease Period or the
          actual vacating of the Premises, furnish the Company with
          confirmations from the Electricity Corporation and the local authority
<PAGE>

                                       60

          that the Lessee has no indebtedness arising from electricity
          consumption and/or water consumption and/or taxes and/or dues to the
          local authority with respect to the Premises up to the expiration of
          the Lease Period or up to the date of actual vacating, whichever of
          the two shall be the later.


     53.2 Without derogating from any of the Company's other rights, should the
          Lessee fail to vacate the Premises  as set forth in sub-paragraph 53.1
          above, the Lessee shall pay the Company pre-determined and pre-
          estimated compensation (hereinafter: "the Compensation") for each day
          in default, in an amount equal to double the Rental Fees applicable to
          the Premises for one day's Rental Fee during the last month of the
          last year of the lease. The Compensation shall be linked to the Index,
          and the computation of the linkage differentials shall be effected,
          mutatis mutandis, by the Company monthly.

     53.3 The foregoing shall not in any manner be construed as prejudicing
          and/or derogating from any right of the Company, including its right
          to receive the Compensation referred to in sub-paragraph 53.2, even if
          the Company had issued a demand and/or invoice to the Lessee for
          payment of rental.

          In addition, nothing contained in this sub-paragraph shall be
          construed as prejudicing and/or derogating from the Company's right to
          demand the vacating of the Premises.

          The provisions of this paragraph take precedence over any other
          provision contained in this Agreement.

          For the avoidance of doubt, it is clarified that the Lessee's
          liability as set forth in this paragraph shall also apply after the
          expiration of the Lease Period up to the actual vacating of the
          Premises.

     53.4 Upon the expiration of the validity of this Agreement, and/or should
          this Agreement be cancelled by the Company and/or should a judgement
          be granted for the eviction of the Lessee  from the Premises, and
          should the Lessee fail to vacate the Premises forthwith, the Company
          shall be entitled to realise and/or to utilise any collateral and/or
          guarantee furnished to it by the Lessee.

          Nothing contained in this paragraph shall be construed as a waiver of
          any of the Company's rights vis-a-vis the Lessee under this Agreement
<PAGE>

                                       61

          or by law, or be construed as giving the Lessee permission to make use
          of the Premises after cancellation of the Lease Agreement or the grant
          of judgement for eviction as aforesaid.

          The cancellation of this Agreement under the provisions of paragraph
          49 above shall in no manner be construed as prejudicing the Lessee's
          obligations pursuant to the provisions of this paragraph above.

     53.5 Without prejudice to any of the Company's rights under this Agreement,
          it is agreed that upon the expiration of the Lease Period and/or after
          cancellation of this Agreement by the Company and/or in the event of
          the Lessee failing to make two consecutive rental payments to the
          Company, should the Lessee fail to vacate the Premises and/or fail to
          restore possession of the Premises to the Company free of any person
          or property, the Company shall be entitled to take possession of the
          Premises, after giving written notice to the Lessee as to the date of
          taking possession.

          The Company shall be entitled to act as set out above and to clear all
          movable property found on the Premises and to store the same as it
          sees fit in its absolute discretion at any other location and/or to
          sell the same to a third party, in its absolute discretion. The cost
          of such clearing, storage and sale shall be due and payable by the
          Lessee. The Company shall be entitled to deduct from the sale price
          (if any) the costs incurred arising from such clearing, storage and
          sale.

          Should the Premises be cleared by the Lessee or should the equipment
          be stored or sold as set forth above in this sub-paragraph, the Lessee
          shall have no plea in defence and/or any other claim against the
          Company in connection with the implementation of such clearing,
          storage or sale as aforesaid, provided that such clearing and/or
          storage is carried out by persons qualified as such, in the presence
          of a representative of the Company, and that storage is effected at a
          suitable location.

     53.6 The Company shall be entitled to take possession of the Premises
          and/or to prevent the Lessee from using the Premises (including the
          replacement of locks on the Premises) in the event the Lessee fails to
          make two consecutive payments of the Rental to the Company provided
          that it had given written notice thereof to the Lessee.

          The books of the Company shall serve as prima facie proof for the
          purpose of the Lessee's indebtedness to the Company for the Rental
<PAGE>

                                       62

          Fees.

     53.7 Further to the provisions of sub-paragraph 53.4 above, the collateral
          shall serve to secure the discharge of all the Lessee's indebtedness
          to the local planning and building committee, to the local authority
          (including any indebtedness arising from water consumption) and/or to
          the Electricity Corporation and the communications service provider
          with respect to the Premises.

54.  Costs of the Agreement
     ----------------------

     The costs of stamping this Agreement shall be due by the parties in equal
     shares.

55.  Taxes, Duties and Levies
     ------------------------

     All such taxes, duties and levies, governmental and/or municipal and/or
     otherwise, and other payments of any kind or nature whatsoever, relating to
     the conduct of the business of the Lessee and/or of the occupier of the
     Premises and/or due in relation to the Premises and/or which shall become
     due by the Lessee and/or in relation to the Premises during the Lease
     Period, shall be payable by the Lessee including such taxes, duties and/or
     levies as are due on the common property (hereinafter: "Compulsory Charges
     in connection with the Common Property"). The Lessee's share of the
     Compulsory Charges in connection with the Common Property shall be
     determined in accordance with the provisions of the Management Agreement.

56.  Value Added Tax
     ---------------

     Any amount and/or security which the Lessee is obliged to pay or deposit
     under this Agreement shall be subject to value added tax at the lawful rate
     as at the date of such payment or deposit payable by the Lessee. Subject to
     the provisions of paragraph 14.2 above, value added tax shall be payable on
     the date prescribed for effecting all such payments or deposits as set
     forth in this Agreement, and against an appropriate tax invoice under law.

57.  Jurisdiction
     ------------

     It is agreed by the parties that they choose the competent court in the Tel
     Aviv district as having exclusive jurisdiction in any matter connected with
     and/or pertaining to this Agreement.

58.  Prohibition against the Set Off of Payments
     -------------------------------------------
<PAGE>

                                       63

     The parties agree that the amounts which they owe and/or shall owe to each
     other arising from this Agreement, or from any cause whatsoever, shall not
     be capable of set off, unless otherwise specified in this Agreement. For
     the avoidance of doubt it is stipulated that where the Lessee has a claim
     and/or demand against the Company, it shall not be entitled to set off the
     amount of such demand and/or claim.

59.  Waivers and Alterations to the Agreement

     59.2 Any waiver of the rights of either party under this Agreement shall be
          effected only in writing and under the signature of those authorised
          to bind that party. Any delay in the utilisation of any rights under
          this Agreement shall not be regarded as a waiver.

     each other shall be regarded as having been delivered within 48 hours from
     the time of dispatch thereof by registered post from a post office in

          in accordance with the foregoing provisions, so long as these do not
          expressly conflict with the provisions of this Agreement and do not
          prejudice its reasonable use of the Premises.

    3.3   For the purpose of the management and rendering of the Services as set
          forth in this Agreement the Company shall be entitled to establish an

               rendering of the Services.

          (c)  To allow the Company and those acting by virtue thereof to enter
               upon the Premises for the purpose of undertaking work connected
               with the management and rendering of the Services, irrespective
               of whether such works are being carried out for the Lessee or for
               any other occupier of the Building, or for the purposes of
               effecting repairs required in other areas of the Building, and

               arising from any interference caused to it as a result thereof.
               In any such instance of the aforesaid acts, the Company shall
               endeavour to ensure that the interference to the Lessee is as
               minimal as possible and that the Premises are restored to their
               former state as soon as possible.

               its inclusion within the framework of the condominium rules
               relating to the Park or to the Building, or through the
               registration of a note as to the existence of this Agreement and

     4.1  The Lessee hereby undertakes to bear, in conjunction with the other
          occupiers of the Building and of the Park, all the costs involved in
          the management and rendering of the Services, including the cost of
          financing involved in the rendering of the Services (hereinafter:
          "the Basic Costs") together with a management fee at the rate of 15%
          of the Basic Costs (hereinafter: "the Management Fee"). The Basic
          Costs together with the Management Fee shall hereinafter be called
          "the Costs".

     4.2  The Lessee's share in all the Costs shall be determined in accordance
          with a key to be prepared by the Company and subject to the provisions
          hereunder. In the apportionment of the Costs among the occupiers in
          the Building and in the Park, the Company shall act as follows:

          (a)  The computation of the Lessee's pro rata share of the Costs
               (hereinafter: "the Pro Rata Share") shall be made by dividing
               the area of the Premises by the total area of the Building or
               Park designated for sale and/or letting, in the absolute
               discretion of the Company.

               Differentials linked to the Index as defined in paragraph 8.3
               hereunder, mutatis mutandis, shall be added to the Lessee's share
               of Costs, where the Base Index for the computation thereof is
               that Index as published on the 15th day of the month prior to the
               date of the notice of demand.

               The Lessee shall not be entitled to appeal against its share in
               the Costs or against any data serving as a basis for the
               computation of its share in the Costs, nor against the date to be
               determined by the Company for the payment thereof.

          (b)  It is hereby agreed that the Company shall be entitled to alter
               the key for the apportionment of the Costs and to lay down
               another ratio between the areas having a different character or
               use in the Building or Park, in its sole discretion, and the
               Lessee shall have no claim and/or demand and/or action against
               the Company in connection therewith. In addition the Company
               shall be entitled to determine a key for the computation of the
               Lessee's share in the Costs as a Pro Rata Share among all
               occupiers of the Park of the Costs with respect to the Park and
               the Building and the rest of
<PAGE>

                                      74

               the Buildings in the Park together or the separate computation of
               the Pro Rata Share of all the occupiers of the Park of the Costs
               with respect to the Common Areas in the Park, and the separate
               computation of the Pro Rata Share of all occupiers of the
               Building of the Costs with respect to the Common Areas in the
               Building only, in its absolute and sole discretion.

          (c)  The Costs shall be payable by the Lessee and the other occupiers
               of the Building and/or the Park in accordance with the provisions
               in paragraph (a) above of this paragraph.

          (d)  The Lessee undertakes to pay to the Company its share of the
               Costs, in accordance with the Company's estimation, for each
               quarter in advance, on the first day of the first calendar month
               for the quarter for which such payment is being made.

               For the purposes of this paragraph "quarter" means: a period of
               three months commencing in January of each year and ending in
               March of each year; a period of three months commencing in April
               of each year and ending in June of each year; a period of three
               months commencing in July of each year and ending in September of
               each year; a period of three months commencing in October of each
               year and ending in December of each year.

     4.3  Notwithstanding the provisions of paragraphs 4.1 and 4.2 above, it is
          agreed that during the course of the first year of the lease, in place
          of the Costs as defined above, the Lessee shall pay to the Company an
          fixed sum of $ 3.50 per month for every square metre of the Area of
          the Premises (as defined in the Lease Agreement).

     4.4  For the avoidance of doubt, it should be hereby clarified that the
          Lessee shall not be liable for any duplication of the payments set
          forth in sub-paragraph 4.1, 4.2 and 4.3 above, and payments which are
          remitted to the Company under sub-paragraph 4.3 above shall cancel
          liability for the payment prescribed in sub-paragraph 4.1 and 4.2
          above, and vice versa.

     4.5  The Lessee hereby undertakes to pay to the Company the amounts set
          forth above, irrespective of whether or not it makes use of the
          Premises, as set forth in paragraph 11 of the Lease Agreement.

     4.6  The Company shall prepare, within a period not exceeding 6 (six)
          months from the end of each calendar year, a final account of the
          Costs
<PAGE>

          during the aforesaid calendar year (hereinafter: "the Annual
          Account") and shall furnish the Lessee with a copy of such Account.
          For the purposes of the preparation of the Annual Account, all income
          and expenditure shall be linked to the Consumer Price Index, on the
          basis of the last known indices, on the date of effecting such income
          or expenditure. The aforesaid Annual Account, audited and confirmed by
          the Company's accountant, shall serve as conclusive proof as to the
          level of the Costs and as to the Lessee's liability for the payment of
          the Costs in accordance therewith.

    4.7   The Lessee hereby undertakes to pay to the Company the differentials,
          if any, between the amounts paid by the Lessee on account of its share
          of the Costs and its share of the Costs as determined in the Annual
          Account. Such payment shall be effected within 7 days from the date of
          submission of the Annual Account by the Company to the Lessee. Should
          the differentials be to the credit of the Lessee, the Lessee's account
          shall be credited accordingly.

    4.8   The Lessee shall pay value added tax to the Company on each payment
          for which it is liable under this Agreement, together with such
          payment, at such rate as shall be applicable at the time of actual
          payment, and it shall receive an appropriate tax invoice from the
          Company.

    4.9   As regard the first calendar year: the Company shall be entitled, in
          its absolute discretion, to submit an Annual Account relating to the
          period commencing on the Effective Date and ending at the end of that
          year, or to add the Annual Accounts relating to this period to the

          payments for which the Lessee is liable with respect to its share of
          the Costs as set forth in paragraphs 4.1 and 4.3 above.

          notice to the Company that they do not wish the subsistence any
          particular service from among the Services provided by the Company at
          that time. In such an event, the Company shall cease to provide that
          service on the expiration of three months from receipt of the
          foregoing notice, provided that should the Company be of the opinion
          that it is essential to maintain the foregoing service in the
          Building, it shall be entitled to approach the managing director of
          the Company and to obtain his final ruling in connection therewith. It
          is hereby recorded that with respect to any service the supply of
          which has been discontinued under this paragraph above, the occupiers
          of the Park shall not be entitled to provide or supply that service

          the occupiers as aforesaid within 30 days from receipt of their
          foregoing request, whether it is possible for it to supply the
          additional services, and if so, when such aforesaid services are to be
          provided and the approximate cost thereof. In the event of the Company

          aforesaid shall be entitled to enter into contractual arrangements
          with any third party whatsoever for the purpose of the provision of
          the service as aforesaid, but only subject to obtaining the prior
          written consent of the Company. The Company shall be entitled to
          refuse its consent as aforesaid should it be of the opinion that
          entering into contractual arrangements as aforesaid is liable to
          prejudice the Company and/or the remaining lessees and/or users of the
          Building and the Park.

     5.4  Any change in the Costs, if required, resulting from the
          discontinuance of the supply of any of the Services or the supply of
          additional services as set out above, shall be determined by the
          Company in its sole discretion and the Lessee shall bear any addition

          or from such earlier date as is prescribed therefor in the Lease
          Agreement.

6.   Value Added Tax

          whatsoever due or which shall become due by it to the Company under

          provisions of this Agreement, the Company shall be entitled, without
          prejudice to its right to any other lawful relief, and at its
          election, to take one or more of the following steps:

               obligation of the Lessee under this Agreement as the Company
               shall see fit.

          (c)  To act in any other manner available to it according to law,

             Index -          means the Consumer Price Index, including
             --------         vegetables Bureau of Statistics. Should the base
                              of the Index be replaced  or should the method
                              of computation and preparation thereof be changed
                              or should it be published by another entity in
                              place of the aforesaid Bureau, the Company shall
                              make the computation of the rise of the
                              Index for the purposes of this clause, by having
                              regard to the foregoing changes.

                              the last Index as shall be known prior to the
             Base Index -     date payment of any of the amounts which the
             ------------     Lessee is obliged to pay as set forth in this A
                              Agreement and not so paid on the due date thereof.

                              the last Index as shall be known on the first
             New Index -      day of the month in which the payment was
             ---------        actually made (hereinafter: "the Effective
                              Date").

             Linkage          the difference between the New Index and the Base
             --------         Index, divided by the Base Index and multiplied
             Differentials -  by the Amount in Arrears.
             ---------------


    8.4   Should the actual payment of the Amount in Arrears be made on any date
          after the Effective Date and up to the last day of the month of
          payment, inclusive, (hereinafter: "the Date of Actual Payment") daily
          interest at a rate to be determined from time to time during the month
          of payment, in unauthorised current overdraft accounts at Bank
          Hapoalim Ltd., shall also be added to the Re-valued Indebtedness, from
          the Effective date to the Date of Actual Payment.

          Any amount paid by the Lessee to the Company arising from any
          indebtedness in arrears shall be split and attributed proportionately
          against the components of the indebtedness in arrears, namely, the
          daily interest component, the annual interest component, the linkage
          differentials component and the Amount in Arrears component.
<PAGE>

                                       80

          indebtedness of the Lessee to the Company as at the Date of Actual
          Payment, the provisions set forth in sub-paragraph 8.2 above shall
          apply with respect to the balance of the Amount in Arrears which had
          not been discharged as set out above.

          relief provided for under this Agreement and in any law, the Lessee

          Arrears, all the costs occasioned to the Company in all matters

          hearing or legal proceedings or Execution Office action, including the
          legal fees of the Company attorney who dealt with the matter
          (hereinafter: "the Legal Costs").

          For the avoidance of doubt it is stipulated that the Lessee shall be
          obliged to refund to the Company all the Costs occasioned to the
          Company arising from the filing of a claim and/or the institution of
          execution proceedings against the Lessee, even though such Costs had
          not been approved by the Court or the Execution Office for payment for
          any reason whatsoever. The Costs set out in this paragraph shall be
          included within the framework of the Company's legal costs and the
          provisions of sub-paragraphs 8.5 and 8.6 hereunder shall also apply
          thereto.

          immediately after receipt of a written demand therefor from the
          Company, together with linkage differentials and interest, as
          indicated above in this paragraph, from the date of dispatch of the
          demand to date of actual payment.

    8.7   The parties agree that the Company's documents shall serve as prima
          facie and conclusive proof as to the amount of the Legal Costs.

9.  The Lessee's Obligation to Effect Payments
    ------------------------------------------

    The Lessee's refusal or unwillingness to receive any service whatsoever
    and/or desire to discontinue the management and rendering of the Services
    with respect to the Premises, in whole or in part, and/or the discontinuance
    of the management and rendering of the Services by the Company, shall not
    release the Lessee from the obligation to participate in all the Costs and
    Management Fees under the conditions of this Agreement.

     regarded as duly delivery to the Lessee.

     In addition to the foregoing, the parties shall be entitled to send notices

The energy center  will be located on the roof including cooling towers, water
pumps and suction exhausts for the ventilation of the toilets and kitchenettes.

Accord will receive from the building:

1.   Condensation water from the energy center  to the floor entrance.
