                                                                    ------------

                                    WARRANT

     to Purchase up to an Aggregate of _______ Convertible Preferred Shares
                           (Subject to Adjustment) of
                   R.T.S. Relational Technology Systems Ltd.
                             at U.S. $___ per share

                VOID AFTER 10:00 a.m. (prevailing Tel Aviv time)

                              on October 30, 2006


    THIS IS TO CERTIFY that the holder specified below ("Holder") is entitled to
purchase, subject to the provisions of this Warrant, from R.T.S. Relational
Technology Systems Ltd. (the "Company"), at any time on or after the date hereof
(the "Effective Date") and until October 30, 2006, an aggregate of up to ______
(subject to adjustment) fully and nonassessable Convertible Preferred Shares,
nominal value New Israeli Shekel ("NIS") 1.00 per share (the "Convertible
Preferred Shares"), of the Company at a price of US$___ per share or the NIS
equivalent thereof (the "Exercise Price").  In the event that all of the
outstanding Convertible Preferred Shares are converted into Ordinary Shares,
this Warrant shall be exercisable solely for such Ordinary Shares and any
references throughout this Warrant to shares of Convertible Preferred Shares
shall be deemed to refer to the Ordinary Shares into which the Convertible
Preferred Shares may be converted. The amount and kind of securities purchasable
pursuant to the rights granted hereunder and the Exercise Price for such
securities are subject to adjustment pursuant to the further provisions of this
Warrant.


1  EXERCISE OF WARRANT

   Subject to the provisions hereof, this Warrant may be exercised in whole
   or in part, at any time or from time to time on or after the Effective Date
   and until October 30, 2006. This Warrant shall be exercised by presentation
   and surrender hereof to the Company at the principal office of  the Company;
   accompanied by

   1.  a written notice of exercise and

   2.  payment to the Company, for the account of the Company, of the Exercise
       Price for the number of Ordinary Shares specified in such notice.

   The Exercise Price for the number of Ordinary Shares specified in the
   notice shall be payable in immediately available good funds, at the option
   of the Holder, in U.S. dollars or the NIS equivalent thereof, based on the
   Representative Rate of Exchange published by the Bank of Israel known as of
   the time of payment.
<PAGE>

                                      -2-

    Upon such presentation and surrender, the Company shall issue promptly to
    the Holder the Convertible Preferred Shares to which the Holder is entitled
    hereunder. In the event the Exercise Price has been paid in U.S. dollars,
    the certificate representing the Convertible Preferred Shares issued upon
    such exercise shall bear a stamp from an Israeli commercial bank confirming
    that the Convertible Preferred Shares  were purchased with foreign currency.
    In the event that the Warrant is exercised pursuant to the net exercise
    provisions below, the Company shall apply to the Bank of Israel, if
    necessary, in order to obtain such stamp.

    If this Warrant should be exercised in part only, the Company shall, upon
    surrender of this Warrant for cancellation, execute and deliver a new
    Warrant evidencing the rights of the Holder to purchase the balance of the
    Convertible Preferred Shares purchasable hereunder. Upon receipt by the
    Company of this Warrant, in proper form for exercise, the Holder shall be
    deemed to be the holder of record of the Convertible Preferred Shares
    issuable upon such exercise, notwithstanding that the share transfer books
    of the Company shall then be closed or that certificates representing such
    Convertible Preferred Shares shall not then be actually delivered to the
    Holder. The Company shall pay any and all expenses, any stamp duty and any
    other charges that may be payable in connection with the issuance of the
    Convertible Preferred Shares and the preparation and delivery of share
    certificates pursuant to this Paragraph 1 in the name of the Holder.

    No fractions of Convertible Preferred Shares shall be issued in connection
    with the exercise of this Warrant, and the number of Convertible Preferred
    Shares issued shall be rounded down to the nearest whole number.


    Notwithstanding the foregoing, in the event of (i) the initial public
    offering of the Company (the "IPO"), (ii) on or after the merger of the
    Company with or into another company or entity, in which the Company is not
    the surviving entity (a "Merger") or (iii) on or after the sale of all or
    substantially all of the assets of the Company (a "Sale") then, in lieu of
    exercising this Warrant as provided above, in whole or in part, the Holder
    may elect to receive simultaneously with the Closing of the IPO, or
    simultaneously with the closing of the Merger or Sale, by the surrender and
    cancellation of this Warrant or any such portion thereof to the Company,
    Convertible Preferred Shares equal to the value of the Warrant (or the
    portion thereof being canceled) by written notice of such election to the
    Company, at the principal office of the Company, in which event the Company
    shall issue to the Holder, for no additional consideration, that number of
    Convertible Preferred Shares computed using the following formula:

                Y(A - B)
        X  =  ------------
                    A

    X   equals the number of Convertible Preferred Shares to be issued to the
        Holder;
<PAGE>

                                      -3-

    Y   equals the number of Convertible Preferred Shares which would otherwise
        have been purchasable under this Warrant (or the portion thereof being
        canceled);

    B   equals the Exercise Price in effect at the time of exercise pursuant to
        this formula (as may have been or be adjusted pursuant to the terms of
        this Warrant); and

    A   shall equal the "Fair Value" of one share of the Company's Convertible
        Preferred Shares.  Fair Value shall mean in the event that this Warrant
        is exercised in accordance with the above formula (i) if in connection
        with an IPO, then the Fair Value shall equal the price (as sold to the
        public) of that number of the Company's Ordinary Shares into which one
        share of the Company's Preferred Shares is Convertible, or (ii) if in
        connection with a Merger or Sale, the value of such share(s) as
        determined for the purposes of the Merger or Sale, or (iii) if other
        than in connection with an IPO or a Merger or Sale and if a public
        market exists for the securities then subject to this Warrant and such
        securities are listed on a U.S. nationally recognized stock exchange or
        on the Nasdaq stock market, then the Fair Value shall equal the last
        sale or trading price of such securities as reported on such exchange or
        market, as applicable; provided, however, if no public market exists for
        the securities then the Fair Value shall be determined in good faith by
        the Board of Directors of the Company, but if such determination is
        challenged in good faith by the Holder, then as determined by an
        independent appraiser mutually satisfactory to the Company and the
        Holder, which determination shall be binding upon the parties.

2.  RESERVATION OF SHARES: PRESERVATION OF RIGHTS

    The Company hereby agrees that at all times it will maintain and reserve
    such number of authorized but unissued Ordinary Shares so that this Warrant
    may be exercised without additional authorization of Convertible Preferred
    Shares after giving effect to all other options, warrants, convertible
    securities and other rights to acquire Convertible Preferred Shares of the
    Company. In addition, the Company will maintain and reserve such number of
    authorized but unissued Ordinary Shares as will be sufficient to permit the
    conversion in full of all issued or issuable Convertible Preferred Shares.
    All shares of Convertible Preferred Shares (and Ordinary Shares issuable
    upon conversion thereof) issuable pursuant to the terms hereof, when issued
    upon exercise of this Warrant in accordance with the terms hereof shall be
    duly and validly issued and fully paid and nonassessable, not subject to
    preemptive rights and shall be free and clear of all liens, encumbrances,
    equities and claims. The Company further agrees that it will not, by charter
    amendment or through reorganization, consolidation, merger, dissolution or
    sale of assets, or by any other voluntary act, avoid or seek to avoid the
    observance or performance of any of the covenants, stipulations or
    conditions to be observed or performed hereunder by the Company.

3.  EXCHANGE OR LOSS OF WARRANT

    This Warrant is exchangeable, upon presentation and surrender hereof at the
    principal office of the Company, only in connection with a partial exercise
    hereof. The Company shall be under no obligation to issue replacement
    warrants for the aggregate number of shares covered hereby except as
    described herein. The term "Warrant" as used herein includes any Warrant or
    Warrants for which this Warrant may be exchanged. Upon receipt by the
    Company of evidence reasonably satisfactory to it of the loss, theft,
    destruction or mutilation of this Warrant, and (in the case of loss, theft
    or destruction) of reasonably satisfactory indemnification, and upon
    surrender and cancellation of this Warrant, if mutilated, the Company will
    execute and deliver a new Warrant of like terms, tenor and date.

4.  ADJUSTMENT

    The number of Convertible Preferred Shares (and the number of Ordinary
    Shares issuable upon conversion thereof) purchasable upon the exercise of
    this Warrant and the Exercise Price shall be subject to adjustment from time
    to time or upon exercise as provided in this paragraph 4.

    4.1  If, during the term of this Warrant, the Company shall distribute a
         stock dividend or shares of capital stock pursuant to a
         reclassification of its Convertible Preferred Shares to the holders of
         Convertible Preferred Shares (i.e., bonus shares), the number of
         Convertible Preferred Shares purchasable upon exercise of this Warrant
         shall be increased by multiplying such number of shares to be purchased
         under this Warrant by a fraction of which the denominator shall be the
         number of Convertible Preferred Shares outstanding at the close of
         business on the day immediately preceding the date of such distribution
         and the numerator shall be the sum of such number of shares and the
         total number of bonus shares, such increase to become effective
         immediately after the opening of business on the date following such
         distribution, and upon the happening of such an event the Exercise
         Price shall be adjusted appropriately.

    4.2  If, during the term of this Warrant, the outstanding Convertible
         Preferred Shares shall be subdivided into a greater number of
         Convertible Preferred Shares, the number of Convertible Preferred
         Shares purchasable upon exercise of this Warrant at the opening of
         business on the day following the day upon which such subdivision
         becomes effective shall be proportionately increased, and, conversely,
         if the outstanding Convertible Preferred Shares shall each be combined
         into a smaller number of Convertible Preferred Shares, the number of
         Convertible Preferred Shares purchasable upon exercise of this Warrant
         at the opening of business on the day following the day upon which such
         combination becomes effective shall be proportionately decreased, and
         in each such case the Exercise Price shall be adjusted appropriately.

   4.3  Reorganization, Reclassification, Merger, Consolidation or Disposition
        ----------------------------------------------------------------------
        of Assets
        ---------

        (a)   In case the Company shall reorganize its capital, reclassify its
              capital stock, consolidate or merge with or into another
              corporation or sell, transfer or otherwise dispose of all or
              substantially all of its property, assets or business to another
              corporation and pursuant to the terms of such reorganization,
              reclassification, merger, consolidation or disposition of assets,
              (i) shares of capital stock of the successor or acquiring
              corporation or of the Company (if it is the surviving corporation)
              or (ii) any cash, shares of stock or other securities or property
              of any nature whatsoever (including warrants or other subscription
              or purchase rights) in addition to or in lieu of capital stock of
              the successor or acquiring corporation ("Other Property") are to
              be received by or distributed to the holders of Convertible
              Preferred Shares of the Company who are holders immediately prior
              to such transaction, then the Holder shall have the right
              thereafter to receive, upon exercise of this Warrant, the number
              of shares of capital stock of the successor or acquiring
              corporation or of the Company, if it is the surviving corporation,
              and Other Property receivable upon or as a result of such
              reorganization, reclassification, merger, consolidation or
              disposition of assets by a holder of the number of shares of
              Convertible Preferred Shares for which this Warrant is exercisable
              immediately prior to such event.

        (b)   In case of any such reorganization, reclassification, merger,
              consolidation or disposition of assets, the successor or acquiring
              corporation shall expressly assume the due and punctual observance
              and performance of each and every covenant and condition of this
              Warrant to be performed and observed by the Company and all the
              obligations and liabilities hereunder, subject to such
              modifications as may be deemed appropriate (as determined by
              resolution of the Board of Directors of the Company) in order to
              provide for adjustments of shares of the Convertible Preferred
              Shares for which this Warrant is exercisable, which modifications
              shall be as nearly equivalent as practicable to the adjustments
              provided for in this Section 4.

        (c)   The provisions of this subsection 4.3 shall similarly apply to
              successive reorganizations, reclassifications, mergers,
              consolidations or disposition of assets.

   4.4  Other Dilutive Events
        ---------------------

        In case any event shall occur as to which the preceding subsections 4.1
        through 4.3 are not strictly applicable but as to which the failure to
        make any adjustment would not fairly protect the purchase rights
        represented by this Warrant in accordance with the essential intent and
        principles hereof
<PAGE>

                                      -6-

        then, in each such case, the Board of Directors of the Company shall, in
        good faith, determine what adjustments are necessary to preserve the
        purchase rights of the Holder represented by this Warrant. The Company
        will notify the Holder of any such adjustments.

5.  NOTICE OF CERTAIN EVENTS

    notices of corporate actions as any holder of Convertible Preferred Shares

    Notwithstanding, in case at any time:

    5.2  There shall be a voluntary or involuntary dissolution, liquidation or

    other property deliverable upon such merger, exchange, sale, dissolution,
    liquidation or winding up, as the case may be. Such written notice shall be
