                            CASH TECHNOLOGIES, INC.


                          SERIES F REDEEMABLE WARRANT

          This warrant certificate (the "Warrant Certificate") certifies that
_________________ or registered assigns, is the registered holder of Series F
Redeemable Warrants to purchase, at any time until 5:00 P.M. New York City time
on August 8, 2006 (the "Expiration Date"), up to 50,000 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 "Series E
Preferred Private Financing") pursuant to the Securities Purchase Agreement
dated as of August 8, 2001 providing for the sale of up to 5 shares of Series E
Preferred Stock and 50,000 Series F Warrants between the Company and the
purchasers named therein.

          1.  Exercise of Warrants.  Each Warrant is initially exercisable to
              --------------------
purchase one Warrant Share at an initial exercise price of $2.00 per share of
the Company's common stock 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 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
<PAGE>

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.  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."

          3.  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

                                       2
<PAGE>

answered to the satisfaction of the Holder. In connection with any purchase of
Warrant Shares the Holder agrees to execute any documents which may be
reasonably required by counsel to the Company to comply with the provisions of
the Act and applicable state securities laws.

          4.  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 closing date for the Series E
Preferred Private Financing.

          5.  Price
              -----

              5.1   Exercise Price.  The exercise price of each Warrant shall be
                    --------------
$2.00 per share of the Company's Common Stock.

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

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

              6.1   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 6.1, 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.

              6.2   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.

              6.3   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.

              6.4   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

                                       3
<PAGE>

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.

          6.5  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.

     7.   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.

     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.

     8.   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.

     9.   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.

    10.   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

                                       4
<PAGE>

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 therefore;

          (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
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.

     11.  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:

such Holder as shown on the books of the Company; or

their respective successors and assigns hereunder.

validity, interpretation, construction, effect and in all other respects by the
internal laws of the State of Delaware.

          13.2    Jurisdiction and Service of Process.  The Company and the
                  -----------------------------------
Holder each (a) agrees that any legal suit, action or proceeding arising out of
