            linked  interest  (all  the  aforegoing  amounts  being  hereinafter
            referred to as "the Secured Sums").

      (b)   Secured  Sums  that are now or in  future  due to the Bank  from the
            Client  in any  foreign  currency  shall be deemed  secured  by this
            Debenture  only insofar as, in respect of the  transaction  pursuant
            whereto  they are due,  an  appropriate  permit  from the  competent
            authorities  in Israel is given in advance  or after the  event,  so
            long as such a permit is legally necessary.

2.    The Client  hereby  undertakes  to pay the Bank  every one of the  Secured
      Sums:

      (a)   on its agreed due date,  if it has been agreed  between the Bank and
            the Client  that the  particular  amount is payable on a  particular
            date;

      (b)   at the end of seven  days from the date of the  Bank's  sending  its
            first  written  demand  to the  Client,  if a due  date has not been
            agreed as provided in paragraph (a) above.

3.    (a)   The Bank may  decline to accept  accelerated  payment of the Secured
            Sums or any of them prior to their due date.

            The Client or anyone  whose  right might be impaired by the grant of
            this  Debenture or its  realisation  shall have no right pursuant to
            section 13(b) of the Pledges Law, 5727-1967 or any other statute.

                                       2


      (b)   In the event that the Bank agrees to the  Client's  application  for
            accelerated payment of any amount on account of the Secured Sums, it
            may charge and collect from the Client  interest  until the due date
            of the amount  accelerated  or  interest  for six  months  after the
            payment, whichever is the shorter period.

4.    (a)   The Bank may compute  interest  on the Secured  Sums at such rate as
            has been or is in future from time to time agreed between it and the
            Client. In cases in which the interest rate has not been agreed, the
            Bank  may fix the  interest  rate  and give  notice  thereof  to the
            Client. The Client shall be charged such interest rates as aforesaid
            and the Bank may add them to principal at the end of each quarter or
            at the end of any other period, as determined by it.

      (b)   In the event of  default  in  payment  of all or any of the  Secured
            Sums,  they shall bear  default  interest at the rate agreed upon in
            the  agreement  for the  provision of the Banking  Services.  In the
            absence of a  provision  with  regard to default  interest  in those
            agreements, the Secured Sums shall bear interest at the maximum rate
            prevailing at the Bank in respect of  unauthorised  withdrawals  and
            defaults on an approved overdraft account, but not less than 2% more
            than the interest  rate fixed in the  agreement for the provision of
            any banking service.

      (c)   In  the  event  that  the  Bank  becomes  entitled  to  realise  the
            collateral  under this  Debenture it may increase the interest rates
            of  the  Secured  Sums  to the  maximum  rate  for  the  time  being
            prevailing at the Bank in respect of  unauthorised  withdrawals  and
            defaults on an approved overdraft account.

      Company hereby grants to the Bank and its successors:

            The said power of attorney is  irrevocable  since third party rights
            are  dependent  thereon.  The Company  shall have no  complaints  in
            connection with  settlements,  waivers and compromises that the Bank
            makes with insurance  companies.  The Bank will exercise it's rights
            only if the  company  is no longer  active or in the event  that the
            Bank is entitled to demand immediate repayment of the Secured Sums.

      (f)   The Company  undertakes,  on the Bank's  first  demand,  to sign all
            applications,  documents and certificates necessary or desirable for
            the  performance  of the  Company's  obligations  contained  in this
            clause.  The Company  further  undertakes not howsoever to cancel or
            modify any of the aforegoing insurance conditions without the Bank's
            prior written consent.

10.   (a)   The  collateral  that has been  given to the Bank  pursuant  to this
            Debenture is of perpetual  character  notwithstanding  settlement of
            all or any of the  Company's  accounts  and it shall remain in force
            until the Bank confirms in writing that this Debenture is void.

      (b)   Should  the Bank  have  been or in  future  be given  collateral  or
            guarantees  for payment of the Secured Sums,  all the collateral and
            guarantees shall be independent of each other.

      (c)   Should the Bank compromise with or grant forbearance or a concession
            to the Company,  should the Bank alter the Company's  obligations in

                                       9


            connection   with  the  Secured  Sums  or  release  or  waive  other
            collateral or guarantees, the same shall not alter the nature of the
            collateral created pursuant to this Debenture and all the collateral
            and  obligations  of the Company  pursuant to this  Debenture  shall
            remain in full force and effect.

11.   The Bank shall have rights of  possession,  lien and set-off  over all the
      amounts,  assets and rights,  including securities,  currency,  gold, bank
      notes  and  documents  for  goods,  insurance  policies,  bills,  cheques,
      obligations,  deposits,  collateral and the proceeds thereof,  that are at
      the Bank at any time to or for the credit of the Company,  including those
      given for collection,  security,  safe keeping or otherwise.  The Bank may
      withhold the said assets until full  discharge of the Secured Sums or sell
      them and  apply all or any of the  proceeds  of sale in  discharge  of the
      Secured Sums.

      In the event that the amounts  that are set off are  deposited  in foreign
      currency, the Company hereby grants the Bank authority and instructions to
      sell the foreign  currency  balance at the rate  obtainable  for it by the
      Bank.

12.   The Bank may at any time charge any of the Company's accounts with it with
      any  amount  now or in  future  due to it from the  Company  and apply any
      amount  that it  receives  from or for the  Company  to the credit of such
      account as it deems fit and transfer any amount  standing to the Company's
      credit in any  account  with it to any other  account  with it as the Bank
      deems fit.

13.   Having  regard to the fact that the amounts that are now and in future due
      to the Bank from the Company on account of the Secured Sums can be both in
      Israeli currency and in foreign currency, it is hereby agreed and declared
      that the Bank and the  receiver,  as the case may be, may convert  Israeli
      currency in their possession to foreign currency as necessary for the full
      or  partial  discharge  of the  Secured  Sums  that are due to the Bank in
      foreign  currency  and convert  foreign  currency in their  possession  to
      Israeli currency,  at the official rates of exchange existing in Israel at
      the time when any such conversions are actually made by either of them.

      The expression "rate of exchange" means:

      (a)   in respect of the time when there is a  restraint  by Israeli law in
            respect of the free use of foreign  currency in Israel - the highest
            amount of Israeli  currency that an Israeli  resident is required to
            pay  for a unit of the  currency


                                       10


            of such  debt to an  entity  duly  licensed  to trade in  Israel  in
            foreign  currency,  together  with  the  bank  commission  for  such
            transaction;

      (b)   in respect of the time when there is no such restraint - the highest
            price  for the  purchase  of a unit  of the  currency  of such  debt
            existing  at the  Bank of  Israel  in  respect  of bank  telegraphic
            withdrawals  on a  city  for  the  time  being  known  as one of the
            financial  centres of the state in which the currency of the debt is
            legal  tender or on New York,  at the  option of the Bank,  together
            with the bank commission for such transaction.

14.   Without  prejudice to the generality of the provisions of this  Debenture,
      the Bank may in any of the  under-mentioned  cases call for the  immediate
      payment of all or any of the Secured  Sums,  without  prior  notice to the
      Company:

      (a)   if the  Client  does  not  discharge  to the Bank on the due date or
            dates any of the Secured Sums due to it;

      (b)   if a voluntary winding-up resolution is passed by the Company and/or
            Medivision  or if a  winding-up  order is issued  against  it by the
            court or if the court calls a  creditors  meeting for the purpose of
            finding an  arrangement  with them or if the Company's name has been
            removed or is about to be removed from any register operated by law;

      (c)   if a (provisional  or permanent)  receiver,  receiver and manager or
            liquidator is appointed over the Company's assets or any of them;

      (d)   if an attachment is imposed over all or any of the Company's  assets
            or over any of the collateral given by the Company to the Bank or if
            any act of execution is taken against it;

      (e)   if the Company stops paying its debts or carrying on its business;

      (f)   if the work or a  substantial  part of it is stopped for two or more
            months;

      (g)   if all or any of the Company's assets are burned,  lost or otherwise
            damaged;

      (h)   if it appears to the Bank,  at its absolute  discretion,  that there
            has been a change in the authority  over the Company,  in comparison
            with the situation existing on the date hereof, by a voluntary share
            transfer or  otherwise,

                                       11


            save for the transfer of the authority in good faith to a transferee
            who holds at least 10% of the  company's  shares on the date hereof,
            and  save for  transfer  of the  authority  to the  shareholders  of
            Medvision.

      (i)   if a receivership or bankruptcy  order is awarded against any of the
            Company's  guarantors  (in the event that the Secured Sums are inter
            alia also  secured  pursuant to  guarantees)  or in the event of the
            death of a guarantor  or in the case of a guardian  being  appointed
            for the person or estate of a  guarantor  and the  Company  does not
            provide the Bank within seven days of the  occurrence  of any of the
            aforegoing  with a guarantee and  undertaking  signed by a person or
            entity agreed in advance by the Bank and in such terms as prescribed
            by the Bank,  pursuant  whereto that person or entity will guarantee
            the Bank  the  full and  punctual  payment  of the  said  sums.  The
            provisions of this sub-clause  shall also apply mutatis  mutandis to
            such  person  or entity as  though  that  person or entity  were the
            original guarantor and also to their successors;

      (j)   if the  Bank,  at its  absolute  discretion,  takes  the view that a
            material   event  has  occurred  that  might  impair  the  Company's
            financial capacity;

      (k)   if,  at  the  Bank's  absolute   discretion  and  in  its  exclusive
            estimation  there is a  material  deterioration  in the value of the
            collateral  that has been  given to secure  payment  of the  Secured
            Sums;

      (l)   if the Company is required to accelerate the discharge of debts that
            it owes to other creditors;

      (m)   if the Company  breaches or does not perform any of its  obligations
            that are contained in this  Debenture  and/or any  agreement  and/or
            instrument  and/or  contract made in the past and/or future  between
            the Company and the Bank;

      (n)   if it transpires  that any material  warranty of the Company in this
            Debenture and/or any contract made in the past and/or future between
            the Company and the Bank is incorrect and/or inaccurate.

      (o)   if the Company alters its articles of  incorporation or some of them
            and does not give notice thereof to the Bank within 48 hours;

                                       12


      (p)   if the Company  passes a resolution  to merge with another  company,
            (other than Medvision)  whether as absorbing or target  company,  as
            defined in the Companies Law,  5759-1999;  and in the opinion of the
            Bank the matter may  adversely  affect the ability of the company to
            repay the credit

      (q)   if any  license,  consent,  approval or  registration  of any of the
            intellectual property rights of the Company is denied, becomes void,
            suspended or is materially prejudiced,  and has a material effect on
            the Company.

      (r)   if it appears  to the Bank that there has been a material  change to
            the business plan of the company or the type of business activity in
            which the company engages without the Bank's prior written consent;

15.   (a)   In each of the cases set out in the preceding  clause,  the Bank may
            take all the steps it deems fit in order to collect  all the Secured
            Sums,  realise  the  collateral  in any way that the law permits and
            exercise  all  its  rights  pursuant  to this  Debenture,  including
            realising the Charged  Property,  in whole or parts and applying the
            proceeds thereof in discharge of the Secured Sums,  without the Bank
            having to enforce or realise any other guarantees or collateral that
            it might have.

      (b)   Upon the giving of such  notice (if any) as may be  required by law,
            the Bank may,  as the  Company's  attorney,  for which  purpose  the
            Company  irrevocably  appoints  the Bank as its  attorney,  sell the
            Charged Property and any part of it by auction, public sale, private
            sale or otherwise, itself or through others and on conditions at the
            Bank's absolute discretion,  and the Bank may itself or by the court
            or execution office realise the collateral granted to it pursuant to
            this  Debenture  or otherwise  by the  appointment  of a receiver or
            receiver  and manager on behalf of the Bank (and the Company  agrees
            in advance to any person or legal  entity that the Bank  appoints or
            proposes as receiver and manager as aforesaid) and amongst his other
            powers, he may:

            (1)   take possession of all or any of the Charged Property;

            (2)   manage the Company's  business or take part in its  management
                  as he deems fit;

                                       13


            (3)   sell or let and/or agree to the sale or letting of the Charged
                  Property,  in whole or parts, or otherwise transfer it on such
                  conditions as he deems fit;

            (4)   make any other  arrangement  in  respect  of all or any of the
                  Charged Property.

16.   All income obtained by the receiver and manager from the Charged  Property
      and all proceeds obtained by the Bank and/or the receiver and manager from
      the sale of the Charged Property or part of it shall be applied:

      (a)   firstly,  in discharge of all expenses  incurred in connection  with
            collecting the Secured Sums, including the expenses and remuneration
            of the receiver or receiver and manager at such rate as fixed by the
            Bank;

      (b)   secondly,  in discharge  of the further  amounts that are due to the
            Bank  in  consequence  of  the  linkage  conditions,  the  interest,
            damages,  commission  and expenses now and in future due to the Bank
            pursuant to this Debenture;

      (c)   thirdly,  in discharge of the  principal of the Secured  Sums, or in
            any other order of application as prescribed by the Bank.

17.   In the event that at the time the Charged Property is realised the Secured
      Sums have not yet fallen due or the Secured  Sums are only due to the Bank
      contingently,  the Bank may collect  from the proceeds of  realisation  an
      amount  sufficient  to  cover  the  Secured  Sums and the  amount  that it
      collects  shall  be  charged  to the  Bank as  collateral  for them and be
      retained by the Bank until their discharge.

18.   Without derogating from the other provisions of this Debenture, no waiver,
      forbearance, concession, silence or abstinence (hereinafter referred to as
      "Waiver")  on the part of the Bank in  respect of the  non-performance  or
      partial  or  incorrect  performance  of any of the  Company's  obligations
      pursuant to this  Debenture  shall be construed as a Waiver by the Bank of
      any right and it shall  only be  treated  as  acquiescence  limited to the
      specific instance in which it was given.

                                       14


      Any Waiver that the Bank grants to any party to a bill that the Bank holds
      pursuant  to  this  Debenture  shall  have  no  effect  whatsoever  on the
      Company's obligations.

19.   (a)   If and  insofar  as the  Company  is made  liable  or  treated  as a
            guarantor (hereinafter referred to as the "Guarantor Company"),  the
            Company hereby agrees that the Bank may:

            (1)   take (or refrain from taking)  proceedings in accordance  with
                  the law in order to realise the collateral  and/or collect the
                  said amounts,  without the Bank first being liable to apply to
                  the guaranteed  debtors to discharge the said amounts that are
                  due from them to the Bank;

            (2)   stop,  modify,  increase,  reduce or renew any credit or other
                  banking service that has been and/or is in future given to the
                  debtors;

            (3)   grant  an  extension  of time  and/or  similar  concession  in
                  connection with the discharge of the said amounts;

            (4)   replace,  renew,  release,  amend,  refrain from performing or
                  realising  collateral or other guarantees that the Bank now or
                  in future holds,  whether  received by it from the  guaranteed
                  debtors or others;

            (5)   compromise with the guaranteed debtors or others.

            (6)   Change the interest rate or fees.

            The  guarantor  Company  hereby  agrees that the doing of any of the
            said  acts by the Bank  shall not vest it with any right to alter or
            revoke its obligations to the Bank.

      (b)   Deleted.

20.   The Company  confirms that the Bank's books and accounts are acceptable to
      it, shall be deemed correct and shall serve as conclusive evidence against
      it of all their  particulars,  including as regards the computation of the
      Secured  Sums,  the  details  of the  bills and  guarantees  and the other
      collateral and every other matter relating to this Debenture.

      may also transfer the said rights without  requiring  further consent from
      the Company.  The transfer may be made by  endorsement of the Debenture or
      in such other manner as the Bank deems fit,  provided  that such  transfer
      shall be made to a Banking Corporation in Israel or abroad.

22.   The Bank may deposit the  collateral  that has been or is in future  given
