$_______________                                                November 1, 2005

      This SENIOR SECURED PROMISSORY NOTE (this "Note") is issued in connection
with an offering (the "Offering") by World Waste Technologies, Inc., a
California corporation (the "Company") of a series of senior secured notes and
common stock purchase warrants, as described in the Company's Private Placement
Memorandum dated as of October 7, 2005, as supplemented. In accordance with the
Offering, this Note is issued pursuant to a series of Subscription Agreements
(individually, a "Subscription Agreement" and collectively, the "Subscription
Agreements"), by and between the Company and each of the investors party thereto
(the "Lenders") and is entitled to the benefits of the Subscription Agreement.
The payment of the principal sum of this Note, including interest accrued
thereon, is secured pursuant to the terms of that certain Security Agreement
dated November 1, 2005 (the "Security Agreement"), by and between the Company
and the Lenders. Capitalized terms used herein and not defined shall have the
meanings ascribed to them in the Subscription Agreement.

      1. Principal and Interest. The Company, for value received, hereby
promises to pay to the order of , or holder (either, the "Holder") in lawful
money of the United States, the principal amount of $ , together with interest
(computed on the basis of a 360 day year) accrued on the unpaid principal of
this Note at the rate of ten percent (10.0%) per annum commencing on the date
hereof and compounding quarterly. Accrued interest on this Note shall be payable
in arrears on December 31, March 31, June 30 and September 30 of each year,
commencing December 31, 2005.

      This Note is due and payable (a) on the earlier of (i) the closing of one
or more equity financings occurring after the date hereof generating gross cash
proceeds to the Company in the aggregate amount of at least $9.0 million,
excluding any proceeds from the sale of securities pursuant to the Offering or
(ii) May 1, 2007 (the first to occur of the foregoing being referred to as the

<PAGE>

"Maturity Date"); provided, however, that the Maturity Date may be extended by
written notice, made by the holders of no less than seventy five percent (75%)
in interest of the principal amount outstanding under all promissory notes
issued pursuant to the Offering (the "Purchased Notes") then outstanding (a
"Qualifying Percentage"), at any time prior to the Maturity Date, or (b) on
demand by written notice following a determination of the holders of a
Qualifying Percentage acting in good faith that an Event of Default has
occurred. The Company shall, on the Maturity Date or, if earlier, within one (1)
business day of receipt of the written notice referred to in the immediately
preceding sentence (the "Payment Date"), pay the outstanding principal and all
accrued and unpaid interest on this Note (as well as any other amounts payable
hereunder) as of the Maturity Date or the Payment Date, as applicable. If upon
the Maturity Date or the Payment Date the amount available for distribution to
each Lender is less than the amount that such Lender is entitled to pursuant to
the Subscription Agreement and such Lender's Note, then the Holder shall receive
such Holder's pro rata share pursuant to the Holder's outstanding principal
amount and accrued but unpaid interest.

      2. Ranking. This Note is issued as a senior secured obligation of the
Company and ranks senior in right of payment to all of the Company's
Subordinated Indebtedness, whether now existing or hereinafter incurred or
created, and pari passu in right of payment with all existing and future Senior
Indebtedness of the Company. "Senior Indebtedness" means any indebtedness of the
Company, unless in the instrument creating or evidencing such indebtedness it is
provided that such indebtedness is subordinate in right of payment to any other
indebtedness of the Company. "Subordinated Indebtedness" means any indebtedness
of the Company that is not Senior Indebtedness.

      3. No Usury. This Note is hereby expressly limited so that in no event
whatsoever, whether by reason of deferment or advancement of loan proceeds,
acceleration of maturity of the loan evidenced hereby, or otherwise, shall the
amount paid or agreed to be paid to the Holder hereunder for the loan, use,
forbearance or detention of money exceed the maximum interest rate permitted by
the laws of the State of California. If at any time the performance of any
provision involves a payment exceeding the limit of the price that may be
validly charged for the loan, use, forbearance or detention of money under
applicable law, then automatically and retroactively, ipso facto, the obligation
to be performed shall be reduced to such limit, it being the specific intent of
the Company and the Holder hereof that all payments under this Note are to be
credited first to interest as permitted by law, but not in excess of (i) the
agreed rate of interest hereunder, or (ii) that permitted by law, whichever is
the lesser, and the balance toward the reduction of principal.

      4. Attorneys' Fees. If the indebtedness represented by this Note or any
part thereof is collected in bankruptcy, receivership or other judicial
proceedings or if this Note is placed in the hands of attorneys for collection
after default, the Company agrees to pay, in addition to the principal and
interest payable hereunder, reasonable attorneys' fees and costs incurred by the
Holder, as well as any and all interest that has accrued on the outstanding
principal after the commencement of bankruptcy, receivership or other judicial
proceedings.

      5. Transfer. The rights and obligations of the Company and the Holder of
this Note will be binding upon and inure to the benefit of the successors,
assigns, heirs, administrators and transferees of the parties hereto.

                                       2

      6. Notices. Any notice, other communication or payment required or
permitted hereunder shall be in writing and shall be deemed to have been given
if delivered as described in the Notices section of the Subscription Agreement
and to the appropriate addresses listed therein.

      In case any one or more Events of Default shall occur and be continuing,
the holders of no less than a Threshold Percentage of the Purchased Notes at the
time outstanding may proceed to protect and enforce the rights of the holders by
an action at law, suit in equity or other appropriate proceeding, whether for
the specific performance of any agreement contained herein or in the

hereunder shall operate as a waiver of such right or any other right. Any term
of this Note or the Security Agreement may be amended or waived with the written
consent of the Company and the holders of no less than a Qualifying Percentage,
as provided in this Note and the Security Agreement. The Holder acknowledges
that because this Note and the Security Agreement may be amended with the
consent of a Qualifying Percentage, and because action by at least a Threshold
Percentage is required to declare this Note to be in default, the Holder's
rights hereunder and thereunder (including, without limitation, the Holder's
rights to receive principal and interest as due) may be amended and waived
without the Holder's consent.

      10. Governing Law. This Note is being delivered in, and shall be governed
by and construed in accordance with, the laws of the State of New York, without
regard to conflicts of laws provisions thereof.

this Note at any time, without penalty or premium.

      12. Miscellaneous. In the event any one or more of the provisions of this
Note shall for any reason be held to be invalid, illegal or unenforceable, in
whole or in part or in any respect, or in the event that any one or more of the
provisions of this Note operate or would prospectively operate to invalidate
this Note, then and in any such event, such provision(s) only shall be deemed
null and void and shall not affect any other provision of this Note and the
remaining provisions of this Note shall remain operative and in full force and
effect and in no way shall be affected, prejudiced, or disturbed thereby.

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
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

                                       9
<PAGE>

service shall constitute good and sufficient service of process and notice
thereof. Nothing in this Section 2.3 shall affect or limit any right to serve
process in any other manner permitted by law.

            2.4 Additional Holders. Additional parties acquiring Warrants
pursuant to the Offering after the date hereof may become parties to this
Agreement by executing the signature page hereto, whereupon such parties shall
be included in the definition of "Holder" for all purposes under this Agreement.

            2.5 Successors and Assigns. Except as otherwise expressly provided
herein, the provisions hereof shall inure to the benefit of, and be binding
upon, the successors, assigns, heirs, executors and administrators of the
parties hereto.

            2.6 Entire Agreement. Except as set forth below, this Agreement and
the other documents delivered pursuant hereto constitute the full and entire
understanding and agreement between the parties with regard to the subjects
hereof and thereof, and this Agreement shall supersede and cancel all prior
agreements between the parties hereto with regard to the subject matter hereof.

            2.7 Notices, etc. All notices and other communications required or
permitted hereunder shall be in writing and shall be delivered by overnight
courier service or mailed by first class mail, postage prepaid, certified or
registered mail, return receipt requested, addressed (a) if to any Holder, at
such party's address as set forth in the Company's records, or at such other
address as such party shall have furnished to the Company in writing, or (b) if
to the Company, at such address as the Company shall have furnished to the
Holder in writing.

            2.8 Severability. In case any provision of this Agreement shall be
invalid, illegal, or unenforceable, the validity, legality and enforceability of
the remaining provisions of this Agreement or any provision of the other
Agreement s shall not in any way be affected or impaired thereby.

            2.9 Titles and Subtitles. The titles of the sections and subsections
of this Agreement are for convenience of reference only and are not to be
considered in construing this Agreement.

            2.10 Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.
