      THIS REGISTRATION RIGHTS AGREEMENT (the "Agreement") is made as of
November 1, 2005, by and among World Waste Technologies, Inc., a California
corporation (the "Company"), and the persons and entities listed on Exhibit A
hereto (each, a "Holder" and, collectively, the "Holders").

                                    RECITALS:

      A. The Company is engaged in an offering (the "Offering") of up to $3.0
million aggregate principal amount of its 10% senior secured bridge notes (plus
up to an additional $3.0 million of notes to cover over-allotments)
(collectively, the "Notes"), together with warrants (the "Warrants") to purchase
shares of the Company's Common Stock, pursuant to the terms of the Company's
Confidential Private Placement Memorandum dated as of October 7, 2005, as
amended.

      B. The sale of the Notes and Warrants is conditional upon the extension of
the rights set forth herein, and by this Agreement the Company and the Holders
desire to provide for certain rights as set forth herein.

      NOW, THEREFORE, in consideration of the foregoing and of the mutual
promises and covenants contained herein, the parties, severally and not jointly,
hereby agree as follows:

                                   AGREEMENT:

                  (b) The term "Registrable Securities" means (i) any and all
shares of Common Stock issued or issuable upon exercise of the Warrants; (ii)
stock issued in lieu of the shares referred to in (i) in any reorganization
which has not been sold to the public; or (iii) stock issued in respect of the

                  (c) The terms "Holder" or "Holders" means any person or
persons to whom Registrable Securities were originally issued or qualifying
transferees under subsection 1.9 hereof who hold Registrable Securities.

                  (d) The term "SEC" means the Securities and Exchange
Commission.

<PAGE>

                  (e) The term "Registration Expenses" shall mean all expenses
incurred by the Company in complying with subsections 1.2 and 1.3 hereof,
including, without limitation, all registration, qualification and filing fees,
printing expenses, escrow fees, fees and disbursements of counsel for the
Company, blue sky fees and expenses, and the expense of any special audits
incident to or required by any such registration (but excluding the compensation
of regular employees of the Company which shall be paid in any event by the
Company).

            1.2 Piggyback Registration. The Company has on file with the SEC a
registration statement on Form SB-2 covering the resale of securities held by
certain of its security holders. This registration statement is currently under
review by the SEC. The Company agrees that it will promptly amend this
registration statement to include the resale of the Registrable Securities (or,
if such an amendment is not permitted by the rules and regulations of the SEC,
the Company will promptly (but in no event later than 180 days from the date
hereof), file a new registration statement with the SEC on Form SB-2 covering
the resale of the Registrable Securities).

            1.3 Expenses of Registration. All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to this
Section 1 shall be borne by the Company except as follows:

                  (a) The Company shall not be required to pay fees or
disbursements of more than one firm of legal counsel to the Holders, such fees
to not exceed $10,000 in the aggregate.

                  (b) The Company shall not be required to pay underwriters'
fees, discounts or commissions relating to Registrable Securities.

            1.4 Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Agreement,
the Company will keep each Holder participating therein advised in writing as to
the initiation of each registration, qualification and compliance and as to the
completion thereof. Except as otherwise provided in subsection 1.4, at its
expense the Company will:

                  (a) Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
Registrable Securities covered by such registration statement (provided that
nothing in this Agreement shall be deemed to preclude the Company from
withdrawing any registration statement at any time, before or after it has been
declared effective by the SEC).

                  (b) Furnish, without charge, to the Holders such numbers of
copies of a prospectus, including each preliminary prospectus, in conformity
with the requirements of the Securities Act, and such other documents as they
may reasonably request in order to facilitate the disposition of Registrable
Securities owned by them. The Holders shall not be entitled to use any selling
materials other than a prospectus and such other materials as may be approved by
the Company, which approval shall not be unreasonably withheld.


                                       2
<PAGE>

                  (c) Use its commercially reasonable efforts to register and
qualify the securities covered by such registration statement under such other
securities or Blue Sky laws of such jurisdictions as shall be reasonably
requested by the Holders or any managing underwriter, provided that the Company
shall not be required in connection therewith or as a condition thereto to
qualify to do business or to file a general consent to service of process in any
such states or jurisdictions.

                  (d) Notify each Holder of Registrable Securities covered by
such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act or the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances then
existing.

                  (e) The Company shall:

                        (i) make available for inspection by a representative of
the Holders, the managing underwriter participating in any disposition pursuant
to such registration statement and one firm of attorneys designated by the
Holders (upon execution of customary confidentiality agreements reasonably
satisfactory to the Company and its counsel), at reasonable times and in
reasonable manner, financial and other records, documents and properties of the
Company that are pertinent to the conduct of due diligence customary for an
underwritten offering, and cause the officers, directors and employees of the
Company to supply all information reasonably requested by any such
representative, underwriter or attorney in connection with a registration
statement as shall be necessary to enable such persons to conduct a reasonable
investigation within the meaning of Section 11 of the Securities Act.

                        (ii) use its commercially reasonable efforts to cause
all Registrable Securities covered by a registration statement to be listed on
any securities exchange or any automated quotation system on which the shares of
common stock of the Company are then listed;

                        (iii) cause to be provided to the Holders that are
selling Registrable Securities pursuant to such registration statement and to
the managing underwriter if any disposition pursuant to such registration
statement is an underwritten offering, upon the effectiveness of such
registration statement, a customary "10b-5" opinion of independent counsel (an
"Opinion") and a customary "cold comfort" letter of independent auditors (a
"Comfort Letter") in each case addressed to such Holders and managing
underwriter, if any;

                        (iv) notify in writing the Holders that are selling
Registrable Securities pursuant to such registration statement and any managing
underwriter if any disposition pursuant to such registration statement is an
underwritten offering, (A) when the registration statement has become effective
and when any post-effective amendment thereto has been filed and becomes
effective, (B) of any request by the SEC or any state securities authority for
amendments and supplements to the registration statement or of any material
request by the SEC or any state securities authority for additional information
after the registration statement has become effective, (C) of the issuance by
the SEC or any state securities authority of any stop order suspending the
effectiveness of the registration statement or the initiation of any proceedings


                                       3
<PAGE>

for that purpose, (D) if, between the effective date of the registration
statement and the closing of any sale of Registrable Securities covered thereby,
the representations and warranties of the Company contained in any underwriting
agreement, securities sales agreement or other similar agreement, including this
Agreement, relating to disclosure cease to be true and correct in all material
respects or if the Company receives any notification with respect to the
suspension of the qualification of the Registrable Securities for sale in any
jurisdiction or the initiation of any proceeding for such purpose, (E) of the
happening of any event during the period the registration statement is effective
such that such registration statement or the related prospectus contains an
untrue statement of a material fact or omits to state a material fact required
to be stated therein or necessary to make statements therein not misleading (in
the case of a prospectus, in light of circumstances under which they were made)
and (F) of any determination by the Company that a post-effective amendment to
the registration statement would be appropriate. The Holders hereby agree to
suspend, and to cause any managing underwriter to suspend, use of the prospectus
contained in a registration statement upon receipt of such notice under clause
(C), (E) or (F) above until, in the case of clause (C), such stop order is
removed or rescinded or, in the case of clauses (E) and (F), the Company has
amended or supplemented such prospectus to correct such misstatement or omission
or otherwise.

      If the notification relates to an event described in clauses (E) or (F),
the Company shall promptly prepare and furnish to each selling Holder and each
underwriter, if any, a reasonable number of copies of a prospectus supplemented
or amended so that, as thereafter delivered to the purchasers of such
Registrable Securities, such prospectus shall not include an untrue statement of
a material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein not misleading.

                        (v) provide and cause to be maintained a transfer agent
and registrar for all such Registrable Securities covered by such registration
statement not later than the effective date of such registration statement;

                        (vi) deliver promptly upon request to each Holder
participating in the offering and each underwriter, if any, copies of all
correspondence between the SEC and the Company, its counsel or auditors and all
memoranda relating to discussions with the SEC and its staff with respect to the
registration statement, other than those portions of any such correspondence and
memoranda which contain information subject to attorney-client privilege with
respect to the Company, and, upon receipt of such confidentiality agreements as
the Company may reasonably request, make reasonably available for inspection by
any Holder of such Registrable Securities covered by such registration
statement, by any underwriter, if any, participating in any disposition to be
effected pursuant to such registration statement and by any attorney, accountant
or other agent retained by any such Holder or any such underwriter, all
pertinent financial and other records, pertinent corporate documents and
properties of the Company, and cause all of the Company's officers, directors
and employees to supply all information reasonably requested by any such Holder,
underwriter, attorney, accountant or agent in connection with such registration
statement;

                        (vii) use commercially reasonable efforts to obtain the
withdrawal of any order suspending the effectiveness of the registration
statement;


                                       4
<PAGE>

                        (viii) provide a CUSIP number for all Registrable
Securities not later than the effective date of any registration statement;

                        (ix) make reasonably available its employees and
personnel and otherwise provide reasonable assistance to the underwriters in the
marketing of Registrable Securities in any underwritten offering;; and

                        (x) cooperate with the sellers of Registrable Securities
and the managing underwriter, if any, to facilitate the timely preparation and
delivery of certificates not bearing any restrictive legends representing the
Registrable Securities to be sold, and cause such Registrable Securities to be
issued in such denominations and registered in such names in accordance with the
underwriting agreement prior to any sale of Registrable Securities to the
underwriters or, if not an underwritten offering, in accordance with the
instructions of the sellers of Registrable Securities at least three business
days prior to any sale of Registrable Securities.

            1.5 Indemnification.

                  (a) The Company will indemnify and hold harmless to the
fullest extent permitted by law each Holder of Registrable Securities and each
of its officers, directors and partners, and each person controlling such
Holder, with respect to which such registration, qualification or compliance has
been effected pursuant to this Agreement, and each underwriter, if any, and each
person who controls any underwriter of the Registrable Securities held by or
issuable to such Holder, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereto) arising out of or based on (i) any
untrue statement (or alleged untrue statement) of a material fact contained in
any registration statement under which such securities were registered under the
Securities Act or the omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading; (ii) any untrue statement (or alleged untrue statement) of a
material fact contained in any preliminary or final prospectus, or based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statement therein, in light of the
circumstances under which they were made, or not misleading, or (iii) any
violation or alleged violation by the Company of the Securities Act, the
Exchange Act or any state securities law applicable to the Company or any rule
or regulation promulgated under the Securities Act, the Exchange Act or any such
state law and relating to action or inaction required of the Company in
connection with any such registration, qualification of compliance, and will
reimburse each such Holder, each of its officers, directors and partners, and
each person controlling such Holder, each such underwriter and each person who
controls any such underwriter, within a reasonable amount of time after incurred
for any reasonable legal and any other expenses incurred in connection with
investigating, defending or settling any such claim, loss, damage, liability or
action; provided, however, that the indemnity agreement contained in this
subsection 1.5(a) shall not apply to amounts paid in settlement of any such
claim, loss, damage, liability, or action if such settlement is effected without
the consent of the Company (which consent shall not be unreasonably withheld);
and provided further, that the Company will not be liable in any such case to
the extent that any such claim, loss, damage or liability arises out of or is
based on any untrue statement or omission based upon written information
furnished to the Company by such Holder or underwriter specifically for use
therein; and provided further, however, that the Company will not be liable in
any such case to the extent that any such claim, loss, damage or liability
arises directly out of or is based primarily upon an untrue statement or
omission made in any preliminary or final prospectus if (i) such Holder failed


                                       5
<PAGE>

to send or deliver a copy of the final prospectus or prospectus supplement with
or prior to the delivery of written confirmation of the sale of the Registrable
Securities and (ii) the final prospectus or prospectus supplement would have
corrected such untrue statement or omission.

                  (b) Each Holder will, if Registrable Securities held by or
issuable to such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, severally and not
jointly, indemnify and hold harmless to the fullest extent permitted by law the
Company, each of its directors and officers, each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company within the meaning of the Securities Act, and each other
such Holder, each of its officers, directors and partners and each person
controlling such Holder, against all claims, losses, expenses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any such registration statement or final prospectus, or based on any omission
(or alleged omission) to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, and will
reimburse the Company, such Holders, such directors, officers, partners, persons
or underwriters for any reasonable legal or any other expenses incurred in
connection with investigating, defending or settling any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement or prospectus in reliance upon
and in conformity with information furnished to the Company by such Holder
specifically for use therein; provided, however, that the indemnity agreement
contained in this subsection 1.5(b) shall not apply to amounts paid in
settlement of any such claim, loss, damage, liability or action if such
settlement is effected without the consent of the Holder (which consent shall
not be unreasonably withheld); and provided further, that the total amount for
which any Holder shall be liable under this subsection 1.5(b) shall not in any
event exceed the net proceeds received by such Holder from the sale of
Registrable Securities held by such Holder in such registration; and provided
further, that a Holder will not be liable in any such case to the extent that
any such claim, loss, damage or liability arises out of or is based on any
untrue statement or omission based upon written information furnished to the
Holder by the Company or underwriter specifically for use therein.

                  (c) Each party entitled to indemnification under this
subsection 1.5 (the "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld), and the Indemnified Party may participate in such
defense at such party's expense; and provided further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations hereunder, except to the extent such
failure resulted in material prejudice to the Indemnifying Party; and provided
further, that an Indemnified Party (together with all other Indemnified Parties
which may be represented without conflict by one counsel) shall have the right
to retain one separate counsel, with the fees and expenses to be paid by the
Indemnifying Party, if representation of such Indemnified Party by the counsel


                                       6
<PAGE>

retained by the Indemnifying Party would be inappropriate due to actual or
potential differing interests between such Indemnified Party and any other party
represented by such counsel in such proceeding. No Indemnifying Party, in the
defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all liability
in respect to such claim or litigation.

                  (d) If for any reason the foregoing indemnity is unavailable
or is insufficient to hold harmless an indemnified party under subsection 1.5,
then each Indemnifying Party shall contribute to the amount paid or payable by
such Indemnified Party as a result of any claim in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party, on the one
hand, and the Indemnified Party, on the other hand, with respect to such
offering of securities. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by the Indemnifying Party or the Indemnified Party and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such untrue statement or omission. If, however, the
allocation provided in the second preceding sentence is not permitted by
applicable law, then each Indemnifying Party shall contribute to the amount paid
or payable by such Indemnified Party in such proportion as is appropriate to
reflect not only such relative faults, but also any other relevant equitable
considerations. The parties hereto agree that it would not be just and equitable
if contributions pursuant to this subsection 1.5(d) were to be determined by pro
rata allocation or by any other method of allocation which does not take into
account the equitable considerations referred to in the preceding sentences of
this subsection 1.5(d). The amount paid or payable in respect of any claim shall
be deemed to include any legal or other expenses reasonably incurred by such
Indemnified Party in connection with investigating or defending any such claim.
No person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. Notwithstanding
anything in this subsection 1.5 to the contrary, no Indemnifying Party (other
than the Company) shall be required pursuant to this subsection 1.5(d) to
contribute any amount in excess of the net proceeds received by such
Indemnifying Party from the sale of Registrable Securities in the offering to
which the losses, claims, damages or liabilities of the Indemnified Parties
relate, less the amount of any indemnification payment made pursuant to
subsection 1.5.

                  (e) The indemnity agreements contained herein shall be in
addition to any other rights to indemnification or contribution which any
Indemnified Party may have pursuant to law or contract and shall remain
operative and in full force and effect regardless of any investigation made or
omitted by, or on behalf of, any Indemnified Party and shall survive the
transfer of the Registrable Securities by any such party.

            1.6 Information by Holder. Any Holder or Holders of Registrable
Securities included in any registration shall promptly furnish to the Company
such information regarding such Holder or Holders and the distribution proposed
by such Holder or Holders as the Company may reasonably request and as shall be
required in connection with any registration, qualification or compliance
referred to herein.


                                       7

            1.7 Rule 144 Reporting. With a view to making available to Holders
the benefits of certain rules and regulations of the SEC which may permit the
sale of the Registrable Securities to the public without registration, the
Company agrees at all times to:

                  (a) make and keep public information available, as those terms
are understood and defined in SEC Rule 144;

                  (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act
(at any time after it has become subject to such reporting requirements); and

                  (c) so long as a Holder owns any Registrable Securities, to
furnish to such Holder forthwith upon receipt of a written request a written
statement by the Company as to its compliance with the reporting requirements of
said Rule 144 and of the Securities Act and the Exchange Act, a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed by the Company as the Holder may reasonably request in
complying with any rule or regulation of the SEC allowing the Holder to sell any
such securities without registration.

            1.8 Transfer of Registration Rights. The Holders' rights to cause
the Company to register their securities and keep information available, granted
to them by the Company under subsections 1.2 and 1.7, may be assigned to a
transferee or assignee of (i) at least 100,000 shares (as adjusted for stock
splits, stock dividends, recapitalizations and like events), (ii) the transfer
is in connection with the transfer of all the Registrable Securities of a
Holder, or (iii) to any constituent partners or members of a Holder which is a
partnership or limited liability company, or to affiliates (as such term is
defined in SEC Rule 405) of a Holder, provided, that (a) the Company is given
written notice by such Holder at the time of or within a reasonable time after
said transfer, stating the name and address of said transferee or assignee, and
identifying the securities with respect to which such registration rights are
being assigned; (b) the assignee or transferee of such rights agrees in writing
to be bound by the terms and conditions of this Agreement, and (c) solely as to
transfers pursuant to clause (iii) above, any transferees or assignees agree to
act through a single representative. The Company may prohibit the transfer of
any Holders' rights under this subsection 1.8 to any proposed transferee or
assignee who the Company reasonably believes is a competitor of the Company, or
when such transfer may violate applicable securities laws. Notwithstanding
anything else in this subsection 1.8, any Holder may transfer rights to a
transferee of a Holder's Registrable Securities if such transferee is a partner,
member or shareholder or a retired partner, member or shareholder of such
Holder.

            1.9 "Market Stand-Off" Agreement. Each Holder hereby agrees that,
during the period of duration (not to exceed 180 days) specified by the Company
and an underwriter of common stock or other securities of the Company following
the effective date of a registration statement covering the primary sale of


                                       8
<PAGE>

shares of the Company, it shall not, to the extent requested by the Company and
such underwriter, directly or indirectly sell, offer to sell, contract to sell
(including, without limitation, any short sale), grant any option to purchase,
pledge or otherwise transfer or dispose of (other than to donees who agree to be
similarly bound) any securities of the Company held by it at any time during
such period except common stock included in such registration. In order to
enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
shares of securities of every other person subject to the foregoing restriction)
until the end of such period.

            1.10 Delay of Registration. No Holder shall have any rights to take
any actions to restrain, enjoin, or otherwise delay any registration as the
result of any controversy that might arise with respect to the interpretation or
implementation of this Section 1.

            1.11 Termination of Registration Rights. No Holder shall be entitled
to exercise any right provided for in this Section 1 at any time, and the
obligations of the Company to a Holder under this Section 1 shall terminate with
respect to such Holder, when such Holder may sell all its Registrable Securities
in a three (3) month period under Rule 144 of the Act.

      2. General.

            2.1 Waivers and Amendments. With the written consent of the record
holders of at least a majority of the Registrable Securities, the obligations of
the Company and the rights of the parties under this Agreement may be waived
(either generally or in a particular instance, either retroactively or
prospectively, and either for a specified period of time or indefinitely), and
with the same consent the Company, when authorized by resolution of its Board of
Directors, may enter into a supplementary agreement for the purpose of adding
any provisions to or changing in any manner or eliminating any of the provisions
of this Agreement; provided, however, that no such modification, amendment or
waiver shall reduce the aforesaid percentage of Registrable Securities without
the consent of all of the Holders of the Registrable Securities. Upon the
effectuation of each such waiver, consent, agreement of amendment or
modification, the Company shall promptly give written notice thereof to the
record holders of the Registrable Securities who have not previously consented
thereto in writing. This Agreement or any provision hereof may be changed,
waived, discharged or terminated only by a statement in writing signed by the
party against which enforcement of the change, waiver, discharge or termination
is sought, except to the extent provided in this subsection 2.1.

            2.2 Governing Law. This Agreement shall be governed in all respects
by the laws of the State of California without regard the principles of
conflicts of law thereof.

            2.3 Consent to Jurisdiction. 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, 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
