EXHIBIT 10.4

                                WARRANT AGREEMENT

      THIS WARRANT AGREEMENT (this "Agreement") is made and entered into as of
_______________________, 2004, between World Waste Technologies, Inc., a
California corporation (the "Company"), and ____________________________
("Holder").

                                    RECITALS

      WHEREAS, the Company proposes to issue to Holder __________________
(_______) warrants (the "Warrants"), each such Warrant entitling the holder
thereof to purchase one share of common stock, no par value, of the Company (the
"Shares" or the "Common Stock"); and

      WHEREAS, the Warrants which are the subject of this Agreement will be
issued by the Company to Holder as part of consideration related to a private
placement investment made by Holder in the Company.

      NOW, THEREFORE, in consideration of the premises and the mutual agreements
herein set forth, the parties hereto agree as follows:

                                    AGREEMENT

      1. Warrant Certificates. The warrant certificates to be delivered pursuant
to this Agreement (the "Warrant Certificates") shall be in the form set forth in
Exhibit A, attached hereto and made a part hereof, with such appropriate
insertions, omissions, substitutions and other variations as are required or
permitted by this Warrant Agreement.

      2. Right to Exercise Warrants. Each Warrant may be exercised from the date
of this Agreement until 11:59 P.M. (Eastern Standard Time) on the date that is
five (5) years after the date of this Agreement (the "Expiration Date"). Each
Warrant not exercised on or before the Expiration Date shall expire.

      Each Warrant shall entitle its holder to purchase from the Company one
share of Common Stock (each an "Exercise Share") at an exercise price of $0.01
per share, subject to adjustment as set forth below ("Exercise Price").

      The Company shall not be required to issue fractional shares of Common
Stock upon the exercise of this Warrant or to deliver Warrant Certificates which
evidence fractional shares of capital stock. In the event that a fraction of an
Exercise Share would, except for the provisions of this paragraph 2, be issuable
upon the exercise of this Warrant, the Company shall pay to the Holder
exercising the Warrant an amount in cash equal to such fraction multiplied by
the current market value of the Exercise Share. For purposes of this paragraph
2, the current market value shall be determined as follows:

            (a) if the Shares are traded in the over-the-counter market and not
on any national securities exchange and not in the NASDAQ Reporting System, the
average of the mean between the last bid and asked prices per share, as reported
by the National Quotation Bureau, Inc., or an equivalent generally accepted
reporting service, for the last business day prior to the date on which the
Warrant is exercised, or, if not so reported, the average of the closing bid and
asked prices for a Share as furnished to the Company by any member of the
National Association of Securities Dealers, Inc., selected by the Company for
that purpose.

            (b) if the Shares are listed or traded on a national securities
exchange or in the NASDAQ Reporting System, the closing price on the principal
national securities exchange on which they are so listed or traded or in the
NASDAQ Reporting System, as the case may be, on the last business day prior to
the date of the exercise of the Warrant. The closing price referred to in this
Clause (b) shall be the last reported sales price or, in case no such reported
sale takes place on such day, the average of the reported closing bid and asked
prices, in either case on the national securities exchange on which the Shares
are then listed on in the NASDAQ Reporting System; or


                                     1 of 5
<PAGE>

            (c) if no such closing price or closing bid and asked prices are
available, as determined in any reasonable manner as may be prescribed by the
Board of Directors of the Company.

      3. Mutilated or Missing Warrant Certificates. In case any of the Warrant
Certificates shall be mutilated, lost, stolen or destroyed prior to the
Expiration Date, the Company shall issue and deliver, in exchange and
substitution for and upon cancellation of the mutilated Warrant Certificate, or
in lieu of and in substitution for the Warrant Certificate lost, stolen or
destroyed, a new Warrant Certificate of like tenor and representing an
equivalent right or interest.

      4. Reservation of Shares. The Company will at all times reserve and keep
available, free from preemptive rights, out of the aggregate of its authorized
but unissued Shares or its authorized and issued Shares held in its treasury for
the purpose of enabling it to satisfy its obligation to issue Exercise Shares
upon exercise of Warrants, the full number of Exercise Shares deliverable upon
the exercise of all outstanding Warrants.

      The Company covenants that all Exercise Shares which may be issued upon
exercise of Warrants will be validly issued, fully paid and non-assessable
outstanding Shares of the Company.

      5. Rights of Holder. The Holder shall not, by virtue of anything contained
in this Warrant Agreement or otherwise, prior to exercise of this Warrant, be
entitled to any right whatsoever, either in law or equity, of a stockholder of
the Company, including without limitation, the right to receive dividends or to
vote or to consent or to receive notice as a stockholder in respect of the
meetings of stockholders or the election of directors of the Company of any
other matter.

      6. Investment Intent; Accredited Investor. Holder represents and warrants
to the Company that Holder is acquiring the Warrants for investment purposes and
with no present intention of distributing or reselling any of the Warrants.
Holder represents that it is an "accredited investor" within the meaning of Rule
501 of Regulation D under the Securities Act (the "Act") and has executed and
delivered the Investment Representation Statement that accompanies this
Agreement.

      7. Certificates to Bear Legend. The Warrants and the certificate or
certificates therefore shall bear the following legend by which each holder
shall be bound:

      "THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED
      OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER
      SUCH ACT OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL, REASONABLY
      SATISFACTORY TO THE CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS
      NOT REQUIRED."

            The Exercise Shares and the certificate or certificates evidencing
any such Exercise Shares shall bear the following legend:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
      UNDER THE SECURITIES ACT OF 1933. THE SHARES MAY NOT BE SOLD OR
      TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF COUNSEL
      THAT AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT IS AVAILABLE."

      Certificates for Warrants or Exercise Shares, as the case may be, without
such legend shall be issued if such Warrants or Exercise Shares are sold
pursuant to an effective registration statement under the Act or if the Company
has received an opinion from counsel reasonably satisfactory to counsel for the
Company that such legend is no longer required under the Act.


                                     2 of 5

      8. Adjustment of Number of Shares and Class of Capital Stock Purchasable.
The number of Exercise Shares and class of capital stock purchasable under this
Warrant are subject to adjustment from time to time as set forth in this Section
8.

            (a) Adjustment for Change in Capital Stock. If the Company:

                  (i)   pays a dividend or makes a distribution on its Common
                        Stock, in each case, in shares of its Common Stock;

                  (ii)  subdivides its outstanding shares of Common Stock into a
                        greater number of shares;

                  (iii) combines its outstanding shares of Common Stock into a
                        smaller number of shares;

                  (iv)  makes a distribution on its Common Stock in shares of
                        its capital stock other than Common Stock; or

                  (v)   issues by reclassification of its shares of Common Stock
                        any shares of its capital stock;

then the number and classes of Exercise Shares purchasable upon exercise of each
Warrant in effect immediately prior to such action shall be adjusted so that the
holder of any Warrant thereafter exercised may receive the number and classes of
shares of capital stock of the Company which such holder would have owned
immediately following such action if such holder had exercised the Warrant
immediately prior to such action.

            For a dividend or distribution the adjustment shall become effective
immediately after the record date for the dividend or distribution. For a
subdivision, combination or reclassification, the adjustment shall become
effective immediately after the effective date of the subdivision, combination
or reclassification.

            If after an adjustment the holder of a Warrant upon exercise of it
may receive shares of two or more classes of capital stock of the Company, the
Board of Directors of the Company shall in good faith determine the allocation
of the adjusted Exercise Price between or among the classes of capital stock.
After such allocation, that portion of the Exercise Price applicable to each
share of each such class of capital stock shall thereafter be subject to
adjustment on terms comparable to those applicable to the Exercise Shares in
this Agreement. Notwithstanding the allocation of the Exercise Price between or
among shares of capital stock as provided by this Section 8(a), a Warrant may
only be exercised in full by payment of the entire Exercise Price in effect at
the time of such exercise.

            (b) Consolidation, Merger or Sale of the Company. If the Company is
a party to a consolidation, merger or transfer of assets which reclassifies or
changes its outstanding Common Stock, the successor corporation (or corporation
controlling the successor corporation or the Company, as the case may be) shall
by operation of law assume the Company's obligations under this Agreement. Upon
consummation of such transaction, the Warrants shall automatically become
exercisable for the kind and amount of securities, cash or other assets which
the holder of a Warrant would have owned immediately after the consolidation,
merger or transfer if the holder had exercised the Warrant immediately before
the effective date of such transaction. As a condition to the consummation of
such transaction, the Company shall arrange for the person or entity obligated
to issue securities or deliver cash or other assets upon exercise of the Warrant
to, concurrently with the consummation of such transaction, assume the Company's
obligations hereunder by executing an instrument so providing and further
providing for adjustments which shall be as nearly equivalent as may be
practical to the adjustments provided for in this Section 8.


                                     3 of 5

      9. Successors. All the covenants and provisions of this Agreement by or
for the benefit of the Company or Holder shall bind and inure to the benefit of
their respective successor and assigns hereunder.

      10. Counterparts. This Agreement may be executed in any number of
counterparts and each of such counterparts shall for all proposes be deemed to
be an original, and such counterparts shall together constitute by one and the
same instrument.

      11. Notices. All notices or other communications under this Agreement
shall be in writing and shall be deemed to have been given if delivered by hand
or mailed by certified mail, postage prepaid, return receipt requested,
addressed as follows: if to the Company: World Waste Technologies, Inc., 13520
Evening Creek Drive North, Suite 130, San Diego, CA 92128, Attention: Chief
Executive Officer, and to the Holder: at the address of the Holder appearing on
the books of the Company or the Company's transfer agent, if any.

      Either the Company or the Holder may from time to time change the address
to which notices to it are to be mailed hereunder by notice in accordance with
the provisions of this Paragraph 11.

      12. Supplements and Amendments. The Company may from time to time
supplement or amend this Agreement without the approval of any Holders in order
to cure any ambiguity or to be correct or supplement any provision contained
herein which may be defective or inconsistent with any other provision, or to
make any other provisions in regard to matters or questions herein arising
hereunder which the Company may deem necessary or desirable and which shall not
materially adversely affect the interest of the Holder.

      13. Severability. If for any reason any provision, paragraph or term of
this Agreement is held to be invalid or unenforceable, all other valid
provisions herein shall remain in full force and effect and all terms,
provisions and paragraphs of this Agreement shall be deemed to be severable.

      14. Governing Law, Venue Consent to Jurisdiction. This Agreement shall be
deemed to be a contract made under the laws of the State of California and for
all purposes shall be governed and construed in accordance with the laws of said
State. The Company and each Holder (i) hereby irrevocably submit to the
non-exclusive jurisdiction of the United States District Court for the Southern
District of California and the courts of the State of California located in the
City of San Diego, California, for the purposes of any suit, action or
proceeding arising out of or relating to this Agreement or the Subscription
Agreement, and (ii) hereby waive, and agree not to assert in any such suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is brought in an
inconvenient forum or that the venue of the suit, action or proceeding is
improper. The Company and each Holder consent to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address in effect for notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing in this Section 14 shall affect or limit any right to serve
process in any other manner permitted by law.

      15. Headings. Paragraphs and subparagraph headings, used herein are
included herein for convenience of reference only and shall not affect the
construction of this Agreement nor constitute a part of this Agreement for any
other purpose.

THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE
TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR PURSUANT
TO RULE 144 OR AN OPINION OF COUNSEL, REASONABLY SATISFACTORY TO THE CORPORATION
AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.

                           WARRANT TO PURCHASE SHARES
                               OF COMMON STOCK OF
                          WORLD WASTE TECHNOLOGIES, INC


Initial Number of Shares:         ______________
Initial Exercise Price:           $0.01 per share
Date of Grant:                    _____________________, 2004
Expiration Date:                  _____________________, 2009

THIS CERTIFIES THAT, ______________________, or any person or entity to whom the
interest in this Warrant is lawfully transferred ("Holder") is entitled to
purchase the above number (as adjusted pursuant to Section 4 hereof) of fully
paid and non-assessable shares of the Common Stock (the "Shares") of World Waste
Technologies, Inc., a California corporation (the "Company), having an Initial
Exercise Price as set forth above, subject to the provisions and upon the terms
and conditions set forth herein and in the Warrant Agreement dated
__________________________, 2004. The exercise price, as adjusted from time to
time as provided herein, is referred to as the "Exercise Price."

      1. Term. The purchase right represented by this Warrant is exercisable, in
whole or in part, at any time commencing on the Date of Grant and ending on the
Expiration Date, after which time the Warrant shall be void.

      2. Method of Exercise; Payment; Issuance of New Warrant. Subject to
Section 1 hereof, the right to purchase Shares represented by this Warrant may
be exercised by Holder, in whole or in part, for the total number of Shares
remaining available for exercise by the surrender of this Warrant (with the
notice of exercise form attached hereto as Exhibit A duly executed) at the
principal office of the Company and by the payment to the Company, by check made
payable to the Company drawn on a United States bank and for United States
funds, or by delivery to the Company of evidence of cancellation of indebtedness
of the Company to such Holder, of an amount equal to the then applicable
Exercise Price per share multiplied by the number of Shares then being purchased
or by net exercise pursuant to Section 6 hereof. In the event of any exercise of
the purchase right represented by this Warrant, certificates for the Shares so
purchased shall be promptly delivered to Holder and, unless this Warrant has
been fully exercised or has expired, a new Warrant representing the portion of
the Shares, if any, with respect to which this Warrant shall not then have been
exercised shall also be promptly delivered to Holder.

      3. Exercise Price. The Exercise Price at which this Warrant may be
exercised shall be the Initial Exercise Price, as adjusted from time to time
pursuant to Section 4 hereof.

      4. Reclassification, Reorganization, Consolidation or Merger. In the case
of any reclassification of the Shares, or any reorganization, consolidation or
merger of the Company with or into another corporation (other than a merger or
reorganization with respect to which the Company is the continuing corporation
and which does not result in any reclassification of the Shares), the Company,
or such successor corporation, as the case may be, shall execute a new warrant
providing that the Holder shall have the right to exercise such new warrant and
upon such exercise to receive, in lieu of each Share theretofore issuable upon
exercise of this Warrant, the number and kind of securities, money and property
receivable upon such reclassification, reorganization, consolidation or merger
by a holder of Shares for each Share. Such new warrant shall provide for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Section 4 including, without limitation,
adjustments to the Exercise Price and to the number of Shares issuable upon
exercise of this Warrant. The provisions of this Section 4 shall similarly apply
to successive reclassifications, reorganizations, consolidations or mergers.


                                     1 of 4
<PAGE>

      5. Transferability and Negotiability of Warrant. This Warrant may not be
transferred or assigned in whole or in part without compliance with applicable
federal and state securities laws by the transferor and the transferee
(including, without limitation, the delivery of investment representation
letters and legal opinions reasonably satisfactory to the Company, if reasonably
requested by the Company). Subject to the provisions of this Section 5, title to
this Warrant may be transferred in the same manner as a negotiable instrument
transferable by endorsement and delivery.

      6. Net Exercise. In lieu of exercising this Warrant for cash, the Holder
may elect to exchange this Warrant for Shares equal to the value of this Warrant
by surrender of this Warrant, together with notice of such election, at the
principal office of the Company, in which event the Company shall issue to the
holder a number of Shares computed using the following formula:

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

            X= the number of Shares to be issued to the holder.
            Y= the number of Shares purchasable under this Warrant.
            A= value per share of one Share determined in accordance with
            Section 2 of the Warrant Agreement.
            B= the Exercise Price (as adjusted).

      7. Miscellaneous. The Company covenants that it will at all times reserve
and keep available, solely for the purpose of issue upon the exercise hereof, a
sufficient number of Shares to permit the exercise hereof in full. Such Shares,
when issued in compliance with the provisions of this Warrant and the Company's
Certificate of Incorporation, will be duly authorized, validly issued, fully
paid and non-assessable. No Holder of this Warrant, as such, shall, prior to the
exercise of this Warrant, be entitled to vote or receive dividends or be deemed
to be a stockholder of the Company for any purpose, nor shall anything contained
in this Warrant be construed to confer upon Holder, as such, any rights of a
stockholder of the Company or any right to vote, give or withhold consent to any
corporate action, receive notice of meetings, receive dividends or subscription
rights, or otherwise. Upon receipt of evidence reasonably satisfactory to the
Company of the loss, theft, destruction or mutilation of this Warrant and, in
the case of any such loss, theft or destruction, upon delivery of an indemnity
agreement reasonably satisfactory in form and amount to the Company or, in the
case of any such mutilation, upon surrender and cancellation of such Warrant,
the Company at its expense will execute and deliver, in lieu thereof, a new
Warrant of like date and tenor. The terms and provisions of this Warrant shall
inure to the benefit of, and be binding upon, the Company and the Holder hereof
and their respective successors and assigns. This Warrant shall be governed by
and construed under the laws of the State of California.

Holder:                                Company:

      In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Company the following:

      (a) I am aware of the Company's business affairs and financial condition,
and have acquired sufficient information about the Company to reach an informed

purposes of the Securities Act of 1933 ("Securities Act").

      (b) I understand that the Securities have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of my investment intent
as expressed herein.

      (c) I further understand that the Securities must be held indefinitely
unless subsequently registered under the Securities Act or unless an exemption
from registration is otherwise available. In addition, I understand that the
certificate evidencing the Securities will be imprinted with a legend which
prohibits the transfer of the Securities unless they are registered or such
registration is not required in the opinion of counsel for the Purchaser
satisfactory to the Company or receipt of a no-action letter from the Securities
and Exchange Commission.

      (d) I am aware of the provisions of Rule 144, promulgated under the
Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or indirectly, from the issuer
thereof (or from an affiliate of such issuer), in a non-public offering subject
to the satisfaction of certain conditions, if applicable, including, among other
things: the availability of certain public information about the Company; the
resale occurring not less than one year after the party has purchased and paid
for the securities to be sold; the sale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934); and
the amount of securities being sold during any three month period not exceeding
the specified limitations stated therein.

      (e) I further understand that at the time I wish to sell the Securities
there may be no public market upon which to make such a sale, and that, even if
such a public market then exists, the Company may not be satisfying the current
public information requirements of Rule 144, and that, in such event, I may be
precluded from selling the Securities under Rule 144 even if the one-year
minimum holding period had been satisfied.

      (f) I further understand that in the event all of the requirements of Rule
144 are not satisfied, registration under the Securities Act, compliance with
Regulation A, or some other registration exemption will be required; and that,
notwithstanding the fact that Rule 144 is not exclusive, the Staff of the SEC
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rule 144 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.
