1.   Consideration.  FOR VALUE RECEIVED, IIS INTELLIGENT INFORMATION SYSTEMS
     LIMITED (the "Company"), an Israeli company, with offices at Gutwirth
     Science-Based Industrial Center, Technion City, Haifa 32000, Israel, hereby
     promises to pay to the order of __________, whose address is
     ____________________, or its registered assigns (hereinafter, the
     "Registered Holder"), the principal sum of _________ Dollars ($________),
     in lawful money of the United States, on the "Maturity Date" (as defined
     below), with interest thereon from December 20, 2000 in like money at the
     rate of LIBOR plus one and a half percent (1.5%) per annum on the unpaid
     balance of this Debenture until paid or converted.  Interest on this
     Debenture shall be payable quarterly, on the first business day of March,
     June, September and December of each year, commencing March 2001. The first
     interest payment will include interest accrued from December 20, 2000.

     The interest shall be increased by one percent (1%) for every four (4)
     weeks of delay by the Company in making the filings specified in Sections
     4.c and 4.d of the Securities Purchase Agreement (the "Securities Purchase
     Agreement") of even date by and between the Company and the Purchasers

     Holder). Subject to Section 4 herein, principal payments shall be reduced

     into the Company's Ordinary Shares (the "Ordinary Shares").

     "LIBOR" shall mean the London Inter Bank Offering Rate for three-month
     dollar deposits for similar amounts as published by the Wall Street
     Journal.

     The Company shall repay the principal amount in equal quarterly
     installments on the first business day of  March , June, September and
     December of each


     year, commencing at the beginning of the third year following the issuance
     of the Debenture and ending at the end of the fifth year (each such payment
     date shall be referred to as an "Installment Date"), in such manner that on
     each Installment Date, the Company shall repay 8 1/3 % of the principal
     amount of the Debentures.

2.   Payment.  Principal and interest shall be payable at such address as the
     Registered Holder shall have designated to the Company in writing at least
     fifteen (15) business days prior to each Installment Date and the Maturity
     Date (and, in the event of failure to provide such address, at the address
     specified in section 1 above), in lawful tender of the United States.

3.   Issuance of Notes.  This Debenture has been issued by the Company pursuant
     to the authorization of the Board of Directors of the Company (the "Board")
     and issued pursuant to the Securities Purchase Agreement. Pursuant to the
     Securities Purchase Agreement, the Company issued units (the "Units"), each
     Unit consisting of $100,000 principal amount of the Debentures and 10,000
     three-year non-redeemable warrants (the "Warrants").  Pursuant to the
     Securities Purchase Agreement, $3,000,000 in aggregate principal amount of
     Debentures were issued on the date hereof.  The Securities Purchase
     Agreement contains certain additional terms that are binding upon the
     Company and each Registered Holder of the Debentures.  A copy of the
     Securities Purchase Agreement may be obtained by any Registered Holder of
     the Debentures from the Company upon written request.  Capitalized terms
     used but not defined herein shall have the meanings set forth in the
     Securities Purchase Agreement. The Debentures, together with any debentures
     from time to time issued in replacement thereof, whether pursuant to
     transfer and assignment, partial conversion thereof or otherwise, are
     hereinafter sometimes collectively referred to as the "Debentures."

4.   Conversion Price.  At the option of the Registered Holder hereof, all or
     any part of the unpaid principal amount of this Debenture may, upon
     execution of the Notice of Conversion attached hereto and the surrender of
     this Debenture to the Company for conversion, be convertible at any time
     following the date of issuance of this Debenture (the "Conversion Date")
     into fully paid non-assessable Ordinary Shares of the Company, at a
     conversion price (the "Conversion Price") equal to one (1) Ordinary Share
     for each $3 nominal value of the principal amount of the Debenture.  The
     Conversion Price may be adjusted pursuant to the provisions of Section 9(c)
     hereof.

5.   Conversion and Delivery.  Subject to the limitations set forth below,
     Notice of Conversion may be given at any time after the date hereof.  The
     Company shall convert this Debenture pursuant to such Notice of Conversion
     in accordance with Section 5 of the Securities Purchase Agreement.

     No fractional Ordinary Shares shall be issued upon conversion of this
     Debenture.  The Registered Holder expressly waives his rights to receive a
     certificate for any fractional shares.  If less than all of the unpaid
     principal amount evidenced by this Debenture shall be converted, the
     Company will, upon such exercise of the conversion privilege, execute and
     deliver to the


     Registered Holder hereof a new Debenture (dated the date hereof) evidencing
     the remaining amount of principal then outstanding.

     Notwithstanding the above, in the event that the closing price of the
     Company's Ordinary Shares for a period of at least fifteen (15) consecutive
     trading days is equal to or greater than $6.00, the Company may give
     written notice to the Registered Holder and the entire outstanding amount
     of this Debenture, shall be deemed to have been converted into Ordinary
     Shares of the Company on the day following receipt of such notice.

6.   Early Repayment.  Commencing on the first day of the 10th month following
     December 20, 2000 and ending at the end of the 15th month following the
     said date, the Company may effect early repayment of the Debentures by the
     payment of 166.66% of the principal amount of the Debenture (with respect
     to the principal amount not converted to shares at that time). In the event
     the Company wishes to perform such early repayment, it shall notify the
     Registered Holder, in writing, and shall consummate such early repayment
     within ten (10) days following the date of the notice.  In the event of
     such early repayment the exercise price all of the Warrants shall be
     reduced to US$4 per share.

7.   Covenants.

     (a)  The Company will pay all taxes, assessments and governmental charges
          lawfully levied or assessed upon it, its property and any part
          thereof, and upon its income for profits, and any part thereof, before
          the same shall become delinquent; and will duly observe, and conform
          in all material aspects to, all lawful requirements of any
          governmental authority relative to any of its property, and all
          covenants, terms and conditions upon or under which any of its
          property is held; provided that nothing in this Section 7 shall
          require the Company to observe or conform to any requirement of
          governmental authority or to pay any such tax, assessment or
          governmental charges so long as the validity thereof shall be
          contested in good faith; and provided further the Company shall not be
          required to pay any such taxes, assessments or charges, if, in the
          judgment of the Board, such payment shall not be in the best interests
          of the Company in the conduct of its business.

     (b)  Subject to the other provisions of this Debenture, the Company at all
          times will maintain its corporate existence and right to carry on its
          business and will duly procure all necessary renewals and extensions
          thereof and use its best efforts to maintain, preserve and renew all
          of its rights, powers, privileges and franchises; provided however,
          that nothing herein contained shall be construed to prevent the
          Company from ceasing or omitting to exercise any rights, powers,
          privileges or franchises which, in the judgment of the Board, can no
          longer be profitably exercised, nor to prevent the consolidation,
          merger or liquidation of any subsidiary or subsidiaries of the Company
          with or into the Company.

     (c)  The Company will at no time close its stock transfer books against the
          transfer of any Ordinary Shares issued or issuable upon the conversion



          of, or in lieu of payments on, the Debentures, in any manner which
          interferes with the timely conversion of such Debentures, except as
          may otherwise be required to comply with applicable securities laws
          and the laws of the State of Israel.

     (d)  The Company will not, by amendment of its Memorandum of Association or
          Articles of Association or through any reorganization,
          recapitalization, transfer of assets, consolidation, merger,
          dissolution, issue or sale of securities or any other voluntary
          action, avoid or seek to avoid the observance or performance of any of
          the terms to be observed or performed hereunder or pursuant to the
          Securities Purchase Agreement by the Company, and will at all times
          assist in good faith in the carrying out of all the provisions of this
          Debenture and the Securities Purchase Agreement and in the taking of
          all such action as may be necessary or appropriate in order to protect
          the conversion rights of the Registered Holders of the Debentures
          against impairment.

     (e)  In the event of any taking by the Company of a record of the holders
          of any class of securities for the purpose of determining the holders
          thereof who are entitled to receive any dividend (other than a cash
          dividend) or other distribution, any right to subscribe for, purchase
          or otherwise acquire any shares of stock of any class or any other
          securities or property, or to receive any other right, the Company
          shall mail to each Registered Holder of the Debentures, at least ten
          (10) days prior to the date specified therein, a notice specifying the
          date on which any such record is to be taken for the purpose of such
          dividend, distribution or right, and the amount and character of such
          dividend, distribution or right.

          Notwithstanding anything contained herein to the contrary, no
          adjustment of the Conversion Price shall be made by reason of the
          issuance of shares pursuant to the acquisition by the Company of all
          or substantially all of the stock or assets of any other corporation
          or corporations.

8.   Taxes.  The issuance of certificates representing Ordinary Shares upon the
     conversion of this Debenture shall be made without charge to the converting
     Registered Holder of the Debenture for any tax with respect to such issue.

9.   Floating Charge; Debenture Protection; Full Ratchet.

     (a)  Upon the issuance of the Debentures the Company shall register a
          first degree floating charge over all its assets  according to the
          Debenture in the form attached hereto in Exhibit 1 in favor of each of
          the Registered Holders.

     (b)  Without derogating from the provisions of Section 9(a) above, in the
          event that at any time the Debentures are not converted or repaid in
          full, and the Company issues additional debentures upon preferred
          terms (as to the Conversion Price or Security), then the terms of the


          outstanding Debentures shall be amended to include such preferred
          terms, but this shall not constitute any breach or default hereunder.

     (c)  In addition, until the repayment or conversion of the entire principal
          amount of the Debentures, in the event that the Company issues New
          Securities (as defined below) at a price lower than the Conversion
          Price, the Conversion Price of any part of the principal amount of
          this Debenture which has not been converted by such date will be
          automatically be reduced to such lower price.

          "New Securities" shall mean any shares of the Company, whether or not
          now authorized, and rights, options or warrants to purchase capital
          stock, and securities of any type whatsoever that are, or may become,
          convertible into capital stock; provided that the term "New
          Securities" shall not include (i) shares of the Company issuable upon
          exercise or options or warrants outstanding on the date hereof, 2000
          or issued or granted pursuant to the Warrants;  (ii) securities issued
          to employees and consultants of the Company pursuant to any stock
          option plan or stock purchases or stock bonus arrangement approved by
          the Board of Directors of the Company; (iii) securities issued
          pursuant to payment of any dividend or distribution with respect to
          all of the Company's issued and outstanding capital stock or (iv)
          securities issued to a strategic investor according to a strategic
          investor agreement, which, in addition to its equity investment in the
          Company,  provides significant added value to the Company's business;

               For the purposes of any adjustment of the Conversion Price
          pursuant to this Section 9(c), the following provisions shall be
          applicable:

               (i) In the case of the issuance of Shares for consideration in
          whole or in part in property other than cash, the value of such
          property or consideration other than cash shall be deemed to be the
          fair market value of such property , irrespective of any accounting
          treatment.

               (ii) In the case of the issuance of Shares for consideration in
          whole or in part other than cash or property, the value of such
          consideration shall be deemed to be the aggregate value of such
          Shares, less the value of any other consideration received by the
          Company.

               (iii) In the case of the issuance of options or other rights to
          purchase or subscribe for securities by their terms convertible into
          or exchangeable for shares or options to purchase or other rights to
          subscribe for such convertible or exchangeable securities:

               (A) the aggregate maximum number of Ordinary Shares deliverable
          upon exercise of such options to purchase or rights to subscribe for
          Shares shall be deemed to have been issued at the time such options or
          rights were issued and for a consideration


          equal to the consideration, if any, received by the Company upon the
          issuance of such options or rights plus the minimum purchase price
          provided in such options or rights for the Shares covered thereby;

               (B) the aggregate maximum number of Ordinary Shares deliverable
          upon conversion of, or in exchange for, any such convertible or
          exchangeable securities or upon the exercise of options to purchase or
          rights to subscribe for such convertible or exchangeable securities
          and subsequent conversion or exchange thereof shall be deemed to have
          been issued at the time such securities were issued or such options or
          rights were issued and for a consideration equal to the consideration
          received by the Company for any such securities and related options or
          rights, provided that in making the foregoing calculations, such
          convertible or exchangeable securities shall be deemed to have been
          converted or redeemed; and

               (C) if there is any change in the exercise price of, or number of
          shares deliverable upon exercise of, any such options or rights or
          upon the conversion or exchange of any such convertible or
          exchangeable securities (other than a change resulting from the
          antidilution provisions thereof), then the Conversion Price shall
          automatically be readjusted in proportion to such change.


      (c)  Share Dividend; Subdivision; Split of Shares.  If the number of
           --------------------------------------------
      Ordinary Shares outstanding at any time prior to repayment or conversion
      of this Debenture is increased by a shares dividend payable in Ordinary
      Shares or by a subdivision or split-up of Ordinary Shares, then, following
      the record date fixed for the determination of holders of shares entitled
      to receive such shares dividend, subdivision or split-up, the Conversion
      Price shall be appropriately decreased and the number of Ordinary Shares
      issuable on conversion of the principal amount shall be increased in
      proportion to such increase in outstanding shares.

      (d)  Combination of Shares.  If, at any time prior to repayment or
           ---------------------
      conversion of this Debenture, the number of Ordinary Shares outstanding is
      decreased by a combination of the outstanding Ordinary Shares, then,
      following the record date for such combination, the Conversion Price shall
      be appropriately increased and the number of Ordinary Shares issuable on
      on conversion of the principal amount shall be increased in proportion to
      such increase in outstanding shares.

      (e)  Calculations.  All calculations under this Section 9 shall be made to
           ------------
      the nearest one-tenth of a cent ($0.001) or to the nearest one-tenth of a
      share, as the case may be.

10.  No Rights as Stockholder.  The Registered Holder of this Debenture shall
     not, by reason of the ownership of this Debenture, have any rights
     whatsoever as a stockholder of the Company, or any other rights,
     whatsoever, except as stated in this Debenture and in the Securities
     Purchase Agreement.


11.  Events of Default.  In case one or more of the following events of default
     shall have occurred:

     (a)  default in the due and punctual payment of interest upon or principal
          of any of the Debentures as and when the same becomes due and payable
          either at maturity or otherwise, which such default continues for five
          (5) days; or

     (b)  failure to deliver the Ordinary Shares required to be delivered upon
          conversion of Debentures in the manner and at the time required by
          Section 5 of the Securities Purchase Agreement, which such failure
          continues for five (5) days; or

     (c)  failure on the part of the Company to duly observe or perform any of
          its other covenants or agreements contained in the Debentures or to
          cure any material breach in a material representation contained in the
          Securities Purchase Agreement for a period of forty-five (45) days
          after the date on which written notice of such failure requiring the
          same to be remedied has been given by a Registered Holder to the
          Company; or

     (d)  a decree or order by a court having jurisdiction has been entered
          adjudging the Company a bankrupt or insolvent, or approving a petition
          seeking reorganization of the Company under any applicable bankruptcy
          law and such decree or order has continued undischarged or unstayed
          for a period of ninety (90) days; or a decree or order of a court
          having jurisdiction for the appointment of a receiver or liquidator or
          trustee or assignee in bankruptcy or insolvency of the Company or of
          all or substantially all of its property, or for the winding-up or
          liquidation of its affairs, has been entered, and has remained in
          force undischarged or unstayed for a period of ninety (90) days; or

     (e)  the Company institutes proceedings to be adjudicated a voluntary
          bankrupt, or consents to the filing of a bankruptcy proceeding against
          it, or files a petition or answer or consent seeking reorganization
          under applicable law, or consents to the filing of any such petition
          or to the appointment of a receiver or liquidator or trustee or
          assignee in bankruptcy or insolvency of it or of all or substantially
          all of its property, or makes an assignment for the benefit of
          creditors, or admits in writing its inability to pay its debts
          generally as they become due;

     then, and in each and every such case, so long as such event of default has
     not been remedied and unless the principal of all the Debentures has
     already become due and payable, the holders of not less than seventy five
     percent (75%) in principal amount of the Debentures then outstanding,   by
     notice in writing to the Company, may declare the principal of his
     Debenture then outstanding and the interest accrued thereof, if not already
     due and payable, to be due and payable immediately, and upon any such
     declaration the same shall become and shall be immediately due and payable,
     anything herein contained to the contrary notwithstanding.

     the person in whose name this Debenture is registered as the absolute owner
     hereof, for the purpose of receiving payment of the principal thereof and
     interest hereon, whether or not the same shall be overdue, and for all
     other purposes whatsoever, including but without limitation, the giving of
     any written notices required hereunder, and the Company shall not be
     affected by any notice to the contrary.

     or otherwise, all liability, if any, of that character against any such
     incorporator, stockholder, officer or director being, by the acceptance
     hereof and as part of the consideration for the issue hereof, expressly
