THE WARRANTS REPRESENTED BY THIS CERTIFICATE AND THE SECURITIES ISSUABLE UPON

                          SERIES B REDEEMABLE WARRANT

1.    This warrant certificate (the "Warrant Certificate") certifies that
________________________ or registered assigns, is the registered holder of
Series B Redeemable Warrants to purchase, at any time until 5:00 P.M. New York
City time on August 31, 2002 (the "Expiration Date"), up to _____________ fully-
paid and non-assessable shares, subject to adjustment in accordance with Article
6 hereof (the "Warrant Shares"), of the common stock, par value $.001 per share
(the "Common Stock"), of Cash Technologies, Inc., a Delaware corporation (the
"Company"), subject to the terms and conditions set forth herein.  The warrants
represented by this Warrant Certificate and any warrants resulting from a
transfer or subdivision of the warrants represented by this Warrant Certificate
shall sometimes hereinafter be referred to, individually, as a "Warrant" and,
collectively, as the "Warrants."  This Warrant Certificate is one of a series of
Warrant Certificates being issued as part of a private offering (the "Private
Financing") pursuant to the Company's Confidential Private Offering Memorandum
dated December 31, 1999.

Exercise of Warrants.  Each Warrant is initially exercisable to purchase one
--------------------
Warrant Share at an initial exercise price of $13.00 per Warrant Share, subject
to adjustment as set forth in Article 6 hereof, payable in cash or by check to
the order of the Company, or any combination of cash or check.  Upon surrender
of this Warrant Certificate with the annexed Form of Election to
<PAGE>

Purchase duly executed, together with payment of the Exercise Price (as
hereinafter defined) for the Warrant Shares purchased, at the Company's
principal offices (presently located at 1434 West 11th Street, Los Angeles,
California 90015), the registered holder of the Warrant Certificate (the
"Holder" or "Holders") shall be entitled to receive a certificate or
certificates for the Warrant Shares so purchased. The purchase rights
represented by this Warrant Certificate are exercisable at the option of the
Holder hereof, in whole or in part (but not as to fractional shares). In the
case of the purchase of less than all the Warrant Shares purchasable under this
Warrant Certificate, the Company shall cancel this Warrant Certificate upon its
surrender and shall execute and deliver a new Warrant Certificate of like tenor
for the balance of the Warrant Shares purchasable hereunder.

2.   Redemption by Company.
     ---------------------

     Following the completion of a registration under the Securities Act of
1933, as amended, of the Warrant Shares, and such registration statement is then
effective and allows for the resale of the Warrant Shares by the Holder, the
Company may, on not less than 20 days' prior written notice, redeem this Warrant
at a price of $.01 per Warrant, provided that the last reported sale price of
                                --------
the Company's Common Stock, as officially reported by the principal securities
exchange on which the Common Stock is listed or admitted to trading or as
reported in the National Market System or such other exchange or registered
securities association on which the Common Stock is traded or quoted, has
averaged at least $18.00 per share for the 20 consecutive trading days ending at
least five days prior to the date on which notice is given (subject to any
adjustment as provided in Section 7 hereof).

     In case the Company shall exercise its right to redeem the Warrants, it
shall give or cause to be given notice to the Holders of the Warrants, by
mailing to such Holders a notice of redemption, first class, postage prepaid, at
their last address as shall appear on the records of the Company.  Any notice
mailed in the manner provided herein shall be conclusively presumed to have been
duly given whether or not the Holder receives such notice.

     The notice of redemption shall specify (i) the redemption price, (ii) the
redemption date, which shall in no event be less than thirty (30) days after the
date of mailing of such notice, and (iii) the place where the Warrant shall be
delivered and the redemption price shall be paid.  No failure to mail such
notice nor any defect therein or in the mailing thereof shall affect the
validity of the proceedings for such redemption except as to a holder (a) to
whom notice was not mailed or (b) whose notice was defective.  An affidavit of
the employee or agent of the Company responsible for delivery of the notice,
that such notice of redemption has been mailed shall, in the absence of fraud,
be prima facie evidence of the acts stated therein.  The redemption price
payable to the Holders shall be mailed to such persons at their addresses of
record.
<PAGE>

3.   Issuance of Certificates.    Upon the exercise of the Warrants, the
     ------------------------
issuance of certificates for the Warrant Shares purchased pursuant to such
exercise shall be made forthwith without charge to the Holder thereof including,
without limitation, any tax which may be payable in respect of the issuance
thereof, and such certificates shall (subject to the provisions of Article 3
hereof) be issued in the name of, or in such names as may be directed by, the
Holder thereof; provided, however, that the Company shall not be required to pay
any tax which may be payable in respect of any transfer involved in the issuance
and delivery of any such certificates in a name other than that of the Holder
and the Company shall not be required to issue or deliver such certificates
unless or until the person or persons requesting the issuance thereof shall have
paid to the Company the amount of such tax or shall have established to the
satisfaction of the Company that such tax has been paid.

     The Warrant Certificates and, upon exercise of the Warrants, the
certificates representing the Warrant Shares shall be executed on behalf of the
Company by the manual or facsimile signature of those officers required to sign
such certificates under applicable law.

     This Warrant Certificate and, upon exercise of the Warrants, in part or in
whole, certificates representing the Warrant Shares shall bear a legend
substantially similar to the following:

          "The securities represented by this certificate have not been
          registered under the Securities Act of 1933, as amended ("Act"), and
          may not be offered or sold except (i) pursuant to an effective
          registration statement under the Act,  (ii) to the extent applicable,
          pursuant to Rule 144 under the Act (or any similar rule under such Act
          relating to the disposition of securities), or (iii) upon the delivery
          by the holder to the Company of an opinion of counsel, reasonably
          satisfactory to counsel to the issuer, stating that an exemption from
          registration under such Act is available."

4.   Restriction on Transfer of Warrants.  The Holder of this Warrant
     -----------------------------------
Certificate, by its acceptance thereof, represents and warrants to, and
covenants and agrees with the Company that the Warrants and the Warrant Shares
issuable upon exercise of the Warrants are being acquired for the Holder's own
account as an investment and not with a view to the resale or distribution
thereof and that the Warrants and the Warrant Shares are not registered under
the Act or any state securities or blue sky laws and, therefore, may not be
transferred unless such securities are either registered under the Act and any
applicable state securities law or an exemption from such registration is
available. The Holder of this Warrant Certificate acknowledges that the Holder
is an "accredited investor" within the meaning of Regulation D promulgated under
the Act who has been provided with an opportunity to ask questions of
representatives of the Company concerning the Company and that all such
questions were answered to the satisfaction of the Holder. In connection with
any purchase of Warrant Shares the Holder agrees to execute any
<PAGE>

documents which may be reasonably required by counsel to the Company to comply
with the provisions of the Act and applicable state securities laws.

1.        Registration Rights.  The Holder shall be entitled to all of the
          -------------------
rights and subject to all of the obligations set forth in the Registration
Rights Agreement of the Company, dated as of the initial closing date for the
Private Financing.

2.        Price.
          -----

2.1.      Initial and Adjusted Exercise Price.  The initial exercise price of
          -----------------------------------
each Warrant shall be $13.00 per Warrant Share.  The adjusted exercise price
shall be the price which shall result from time to time from any and all
adjustments of the initial exercise price in accordance with the provisions of
Article 7 hereof.

2.2.      Exercise Price.  The term "Exercise Price" herein shall mean the
          --------------
initial exercise price or the adjusted exercise price, depending upon the
context.

2.3.          Adjustments of Exercise Price and Number of Warrant Shares.
              ----------------------------------------------------------

2.4.      Dividends and Distributions.  In case the Company shall at any time
          ---------------------------
after the date hereof pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock, then upon such dividend or distribution,
the Exercise Price in effect immediately prior to such dividend or distribution
shall be reduced to a price determined by dividing an amount equal to the total
number of shares of Common Stock outstanding immediately prior to such dividend
or distribution multiplied by the Exercise Price in effect immediately prior to
such dividend or distribution, by the total number of shares of Common Stock
outstanding immediately after such dividend or distribution.  For purposes of
any computation to be made in accordance with the provisions of this Section
7.1, the Common Stock issuable by way of dividend or distribution shall be
deemed to have been issued immediately after the opening of business on the date
following the date fixed for determination of shareholders entitled to receive
such dividend or distribution.

2.5.      Subdivision and Combination.  In case the Company shall at any time
          ---------------------------
subdivide or combine the outstanding Common Stock, the Exercise Price shall
forthwith be proportionately decreased in the case of subdivision or increased
in the case of combination.

2.6.      Adjustment in Number of Warrant Shares. Upon each adjustment of the
          --------------------------------------
Exercise Price pursuant to the provisions of this Article 7, the number of
Warrant Shares issuable upon the exercise of each Warrant shall be adjusted to
the nearest full shares of Common Stock by multiplying a number equal to the
Exercise Price in effect immediately prior to such adjustment by the number of
Warrant Shares issuable upon exercise of the Warrants immediately prior to such
adjustment and dividing the product so obtained by the adjusted Exercise Price.
<PAGE>

2.7.      Reclassification, Consolidation, Merger. etc.  In case of any
          --------------------------------------------
reclassification or change of the outstanding shares of Common Stock (other than
a change in par value, or from par value to no par value, or from no par value
to par value, or as a result of a subdivision or combination), or in the case of
any consolidation of the Company with, or merger of the Company into, another
corporation (other than a consolidation or merger in which the Company is the
surviving corporation and which does not result in any reclassification or
change of the outstanding shares of Common Stock, except a change as a result of
a subdivision or combination of such shares or a change in nominal value, as
aforesaid), or in the case of a sale or conveyance to another corporation of the
property of the Company as an entirety, the Holder shall thereafter have the
right to purchase the kind and number of shares of stock and other securities
and property receivable upon such reclassification, change, consolidation,
merger, sale or conveyance as if the Holder were the owner of the Warrant Shares
issuable upon exercise of the Warrants immediately prior to any such events at a
price equal to the product of (x) the number of Warrant Shares issuable upon
exercise of the Warrants and (y) the Exercise Price in effect immediately prior
to the record date for such reclassification, change, consolidation, merger,
sale or conveyance as if such Holder had exercised the Warrants.

2.8.      Determination of Outstanding Shares.  The number of shares of Common
          -----------------------------------
Stock at any one time outstanding shall include the aggregate number of shares
issued or issuable upon the exercise of outstanding options, rights, warrants
and upon the conversion or exchange of outstanding convertible or exchangeable
securities.

3.        Exchange and Replacement of Warrant Certificates.  This Warrant
          ------------------------------------------------
Certificate is exchangeable without expense, upon the surrender hereof by the
registered Holder at the principal executive office of the Company, for a new
Warrant Certificate of like tenor and date representing in the aggregate the
right to purchase the same number of Warrant Shares in such denominations as
shall be designated by the Holder thereof at the time of such surrender.

4.        Upon receipt by the Company of evidence reasonably satisfactory to it
of the loss, theft, destruction or mutilation of this Warrant Certificate, and,
in case of loss, theft or destruction, of indemnity or security reasonably
satisfactory to it, and reimbursement to the Company of all reasonable expenses
incidental thereto, and upon surrender and cancellation of the Warrants, if
mutilated, the Company will make and deliver a new Warrant of like tenor, in
lieu thereof.

5.        Elimination of Fractional Interests.   The Company shall not be
          -----------------------------------
required to issue certificates representing fractions of shares of Common Stock
and shall not be required to issue scrip or pay cash in lieu of fractional
interests, it being the intent of the parties that all fractional interests
shall be eliminated by rounding any fraction up to the nearest whole number of
shares of Common Stock.
<PAGE>

6.        Reservation of Shares.  The Company covenants and agrees that it will
          ---------------------
at all times reserve and keep available out of its authorized share capital,
solely for the purpose of issuance upon the exercise of the Warrants, such
number of shares of Common Stock as shall be equal to the number of Warrant
Shares issuable upon the exercise of the Warrants, for issuance upon such
exercise, and that, upon exercise of the Warrants and payment of the Exercise
Price therefor, all Warrant Shares issuable upon such exercise shall be duly and
validly issued, fully paid, nonassessable and not subject to the preemptive
rights of any shareholder.

7.        Notices to Warrant Holders.  Nothing contained in this Agreement shall
          --------------------------
be construed as conferring upon the Holder or Holders the right to vote or to
consent or to receive notice as a stockholder in respect of any meetings of
stockholders for the election of directors or any other matter, or as having any
rights whatsoever as a shareholder of the Company.  If, however, at any time
prior to the expiration of the Warrants and their exercise, any of the following
events shall occur:

          (a)  the Company shall take a record of the holders of its Common
          Stock for the purpose of entitling them to receive a dividend or
          distribution payable otherwise than in cash, or a cash dividend or
          distribution payable otherwise then out of current or retained
          earnings, as indicated by the accounting treatment of such dividend or
          distribution on the books of the Company; or
          (b) the Company shall offer to all the holders of its Common Stock any
          additional shares of Common Stock or other shares of capital stock of
          the Company or securities convertible into or exchangeable for shares
          of Common Stock or other shares of capital stock of the Company, or
          any option, right or warrant to subscribe therefor;
          (c)  a dissolution, liquidation or winding up of the Company (other
          than in connection with a consolidation or merger) or a sale of all or
          substantially all of its property, assets and business as an entirety
          shall be proposed; or
          (d)  the Company or an affiliate of the Company shall propose to issue
          any rights to subscribe for shares of Common Stock or any other
          securities of the Company or of such affiliate to all the stockholders
          of the Company;
          then, in any one or more of said events, the Company shall give
          written notice of such event at least twenty (20) days prior to the
          date fixed as a record date or the date of closing the transfer books
          for the determination of the stockholders entitled to such dividend,
          distribution, convertible or exchangeable securities or subscription
          rights, options or warrants, or entitled to vote on such proposed
          dissolution, liquidation, winding up or sale. Such notice shall
          specify such record date or the date of closing the transfer books, as
          the case may be. Failure to give such notice or any defect therein
          shall not
<PAGE>

          affect the validity of any action taken in connection with the
          declaration or payment of any such dividend or distribution, or the
          issuance of any convertible or exchangeable securities or subscription
          rights, options or warrants, or any proposed dissolution, liquidation,
          winding up or sale.

             Notwithstanding the foregoing, the Company agrees that it shall
          promptly deliver to the Holder copies of all financial statements,
          reports and proxy statements which the Company is required to send to
          its stockholders generally.

1.        Notices.  All notices, requests, consents and other communications
          -------
hereunder shall be in writing and shall be deemed to have been duly made when
delivered, or mailed by registered or certified mail, return receipt requested:

          Holder as shown on the books of the Company; or

          Agreement or to such other address as the Company may designate by
          notice to the Holders.

respective successors and assigns hereunder.

3.        Governing Law.
          -------------

3.1.      Choice of Law.  This Agreement shall be deemed to have been made and
          -------------
delivered in the State of Delaware and shall be governed as to validity,
interpretation, construction, effect and in all other respects by the internal
laws of the State of Delaware.

3.2.      Jurisdiction and Service of Process.  The Company and the Holder
          -----------------------------------

BOTH THE COMPANY AND HOLDER HEREBY WAIVE TRIAL BY JURY IN ANY ACTION TO ENFORCE
THE TERMS OF THIS WARRANT CERTIFICATE AND IN CONNECTION WITH ANY DEFENSE,

                                                         Los Angeles, California

          FOR VALUE RECEIVED, Cash Technologies, Inc., a Delaware corporation

a Delaware corporation ("Coinbank") and National Cash Processors, Inc., a
Delaware corporation ("NCP" and together with Coinbank sometimes referred to
individually as a "Subsidiary" and together as the "Subsidiaries"), all with an

the context indicates otherwise), with its principal office at 1434 West 11th
Street, Los Angeles, California 90015, promises to pay to the order of
______________________ (the "Payee" or the "Holder"), or registered assigns, the
principal amount of ________________  on July 31, 2001 (the "Maturity Date"),
and unpaid interest on the unpaid principal balance hereof from the date of this
Note at the rate of 10% per annum, payable on the last day of each calender
quarter commencing March 31, 2000.  Payments of principal and interest shall be
made in such coin or currency of the United States of America as at the time of
payment shall be legal tender for the payment of public or private debts.

1.   Terms of Repayment

     1.1  All payments received on account of this Note shall be applied first
to the payment of accrued interest on this Note and then to the reduction of the
unpaid principal balance of this Note.  Interest shall be computed on the basis
of a year of 360 days, for the actual number of days elapsed.  Payor may prepay
principal and interest on this Note upon 30 days prior notice to the Holder.
<PAGE>

     1.2  If payment of the outstanding principal amount of this Note, together
with accrued unpaid interest thereon at the applicable rate of interest (as set
forth herein), is not made on the earlier to occur of (i) the Maturity Date (as
such date may be extended pursuant to the extension options set forth in Section
4 hereof) and (ii) the Accelerated Maturity Date (defined below), then interest
shall accrue on the outstanding principal amount due under this Note and on any
unpaid accrued interest due on this date of the payment in full of such amounts
(including from and after the date of the entry of judgment in favor of the
Holder in an action to collect this Note) at an annual rate equal to the lesser
of 18% or the maximum rate of interest permitted by applicable law.

     1.3  Notwithstanding anything to the contrary contained in this Note, Payor
shall not be obligated pay, and the Holder shall not be entitled to charge,
collect, or receive, interest in excess of the maximum rate allowed by
applicable law.  During any period of time in which the interest rate specified
herein exceeds such maximum rate, any amounts of interest collected by the
Holder in excess of such maximum rate shall be deemed to apply to principal and
all payments of interest and principal shall be recalculated to allow for such
characterization.

     1.4  In the event that the date for the payment of any amount payable under
this Note falls due on a Saturday, Sunday or public holiday under the laws of
the State of California, the time for payment of such amount shall be extended
to the next succeeding business day and interest shall continue to accrue on any
principal amount so effected until the payment thereof on such extended due
date.

3.   Conversion Rights
     -----------------

     3.1  The Holder shall have the right prior to the date on which this Note
is paid in full, to convert at any time, or from time to time, any part of the
outstanding principal amount of this Note into fully paid and non-assessable
shares of the Common Stock par value $.001 per share, of Cashtech (the
"Conversion Rights") at the Conversion Price (as defined below) determined as
provided in this Section 3.  Promptly after the surrender of this Note,
accompanied by a Notice of Conversion of Convertible Note in the form attached
hereto as Exhibit A, properly completed and duly executed by the Holder (a
          ---------
"Conversion Notice"), Cashtech shall issue and deliver to or upon the order of
the Holder that number of shares of Common Stock for the balance of this Note
converted as shall be determined in accordance herewith.

     3.2  The number of shares of Common Stock to be issued upon each conversion
of this Note shall be determined by dividing (i) the amount of Principal to be
converted by (ii) the Conversion Price in effect on the date the Conversion
Notice is delivered to Cashtech by the Holder.

     3.3  Conversion Price.  The conversion price shall be $9.50, subject to
          ----------------
adjustment from time to time upon the happening of certain events (as adjusted,
the "Conversion Price") as set forth below.

     3.4  Subdivision.  If Cashtech, at any time while Notes remain outstanding,
          -----------
shall (i) subdivide the Common Stock (or effect a similar transaction), the
Conversion Price shall be proportionately reduced or (ii) effect a reverse stock
split or similar transaction, the  Conversion Price shall be proportionately
increased, as the case may be, as of the effective date of such subdivision,
reverse stock split or similar transaction, or, if Cashtech shall take a record
of holders of its Common Stock for the purpose of any such transaction, as of
such record date, whichever is earlier (provided if such transaction does not
actually occur, such adjustment shall not be made).

     3.5  Stock Dividends.  If Cashtech at any time while any Notes are
          ---------------
outstanding shall pay a dividend in shares of, or make other distribution of
shares of, the Common Stock, then the Conversion Price shall be adjusted, as of
the date Cashtech shall take a record of the holders of its Common Stock for the
purpose of receiving such dividend or other distribution (or if no such record
is taken, as at the date of such payment or other distribution), to that price
determined by multiplying the Conversion Price in effect immediately prior to
such payment or other distribution by a fraction (a) the numerator of which
shall be the total number of shares of Common Stock outstanding immediately
prior to such dividend or distribution, and (b) the denominator of which shall
be the total number of shares of Common Stock outstanding immediately after such
dividend or distribution.

     3.6   Reclassification, Consolidation or Merger.  At any time while this
           -----------------------------------------
Note remains outstanding, in case of any reclassification or change of Common
Stock (other than a change in
<PAGE>

par value, or from par value to no par value per share, or from no par value per
share to par value or as a result of a subdivision or combination of Common
Stock) or in case of any consolidation or merger of Cashtech with or into
another corporation (other than a merger with another corporation in which
Cashtech is a continuing corporation and which does not result in any
reclassification or change, other than a change in par value, or from par value
to no par value per share, or from no par value per share to par value, or as a
result of a subdivision or combination Common Stock), or in the case of any sale
or transfer to another corporation of the property of Cashtech as an entirety or
substantially as an entirety, Cashtech, or such successor or purchasing
corporation, as the case may be, shall, without payment of any additional
consideration therefor, execute new notes providing that the holders of the
Notes shall have the right to exercise such new notes (upon terms not less
favorable to the holders than those then applicable to the Notes) and to receive
upon such exercise, in lieu of each share of Common Stock theretofore issuable
upon exercise of the Notes, the kind and amount of shares of stock, other
securities, money or property receivable upon such reclassification, change,
consolidation, merger, sale or transfer by the Holder of one share of Common
Stock issuable upon exercise of the Notes had the Notes been converted
immediately prior to such reclassification, change, consolidation, merger, sale
or transfer. Such new notes shall provide for adjustments which shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Section 3. The provisions of this Section 3.6 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, sales and
transfers.

     3.7  Method of Conversion. Except as otherwise provided in this Note or
          --------------------
agreed to by the Holder, this Note may be converted by the Holder in whole at
any time or in part (provided such partial conversion is at least $20,000) from
time to time by (i) submitting to Cashtech a Conversion Notice (by facsimile
dispatched on the Conversion Date and confirmed by U.S. mail or overnight mail
service sent within two business days thereafter) and (ii) surrendering this
Note with the mailed confirmation of the Conversion Notice at the principal
office of Cashtech. Upon partial exercise of the Conversion Rights, a new note
containing the same date and provisions as this Note shall be issued by Cashtech
to the Holder for the balance due hereunder which shall not have been converted.

     3.8  Restrictions on Shares. This Note has been issued by the Company
          ----------------------

have been registered under the Act and applicable state securities laws or (ii)
Cashtech shall have been furnished with an opinion of legal counsel (in form,
substance and scope reasonably acceptable to Cashtech) to the effect that such
sale or transfer is exempt from the registration requirements of the Act.  Each

received an opinion of counsel, reasonably satisfactory to the Maker in form,
substance and scope, to the effect that any such legend may be removed from such
certificate or (ii) a registration statement under the Act covering such

rights granted by the Cashtech pursuant to the terms of the Registration Rights
Agreement entered into by Cashtech in connection with the Offering.
