                                  MISCELLANEOUS

      7.1 Limitation on the Secured Party's Duty in Respect of Collateral. The
Secured Parties shall be deemed to have acted reasonably in the custody,
preservation and disposition of any of the Collateral if they take such action
as the Debtor requests in writing, but failure of the Secured Parties to comply

and no failure of the Secured Parties to do any act not so requested shall be
deemed a failure to act reasonably.

      7.2 Reinstatement. This Security Agreement shall remain in full force and
effect and continue to be effective should any petition be filed by or against

or make an assignment for the benefit of creditors or should a receiver or
trustee be appointed for all or any significant part of the Debtor's property
and assets, and shall continue to be effective or be reinstated, as the case may
be, if at any time payment and performance of the Secured Obligations, or any
part thereof, is, pursuant to applicable law, rescinded or reduced in amount, or
must otherwise be restored or returned by any obligee of the Secured
Obligations, whether as a "voidable preference," "fraudulent conveyance," or
otherwise, all as though such payment or performance had not been made. In the

                                       8
<PAGE>

be waived, amended, supplemented or otherwise modified with the written consent
of the Company and the Secured Parties holding at least 75% in aggregate
principal amount of the Notes issued in the Offering.

      7.7 No Waiver; Remedies Cumulative. No failure or delay on the part of the
Secured Parties in exercising any right, power or privilege hereunder and no
course of dealing between the Debtor shall operate as a waiver thereof; nor
shall any single or partial exercise of any right, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other
right, power or privilege. A waiver by the Secured Parties of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which the Secured Parties would otherwise have on any future
occasion. The rights and remedies herein expressly provided are cumulative and
may be exercised singly or concurrently and as often and in such order as the
Secured Parties deem expedient and are not exclusive of any rights or remedies
which the Secured Parties would otherwise have whether by security agreement or
now or hereafter existing under applicable law. No notice to or demand on the
Debtor in any case shall entitle the Debtor to any other or further notice or
demand in similar or other circumstances or constitute a waiver of the rights of
the Secured Parties to any other or future action in any circumstances without
notice or demand.

      7.8 Termination; Release. When the Secured Obligations have been
indefeasibly paid and performed in full this Security Agreement shall terminate,
and the Secured Parties, at the request and sole expense of the Debtor, will
execute and deliver to the Debtor the proper instruments (including UCC
termination statements) acknowledging the termination of this Security
Agreement, and will duly assign, transfer and deliver to the Debtor, without
recourse, representation or warranty of any kind whatsoever, such of the
Collateral as may be in the possession of the Secured Parties and has not
theretofore been disposed of, applied or released.

                                 2004 STOCK PLAN
                             STOCK OPTION AGREEMENT

      1. GRANT OF OPTION. World Waste Technologies, Inc., a California
corporation (the "Company"), hereby grants to GRANTEE ("Optionee") an option
(the "Option") to purchase a total number of shares of Common Stock (the
"Shares") set forth in the Notice of Stock Option Grant, at the exercise price
per share set forth in the Notice of Stock Option Grant (the "Exercise Price")
subject to the terms, definitions and provisions of the World Waste
Technologies, Inc. 2004 STOCK PLAN (the "Plan") adopted by the Company, which is
incorporated herein by reference. Unless otherwise defined herein, the terms
defined in the Plan shall have the same defined meanings in this Option.

      If designated an Incentive Stock Option, this Option is intended to
qualify as an Incentive Stock Option as defined in Section 422 of the Code.

      2. EXERCISE OF OPTION. This Option shall be exercisable during its Term in
accordance with the Vesting Schedule set out in the Notice of Stock Option Grant
and with the provisions of Section 9 of the Plan as follows:

            (a) RIGHT TO EXERCISE.

                  (i) This Option may be exercised in whole or in part at any
time after the Date of Grant, as to Shares which have not yet vested under the
vesting schedule indicated on the Notice of Stock Option Grant; provided,
however, that Optionee shall execute as a condition to such exercise of this
Option, the Early Exercise Notice and Restricted Stock Purchase Agreement
attached hereto as Exhibit A (the "Early Exercise Agreement"). If Optionee
chooses to exercise this Option solely as to Shares which have vested under the
vesting schedule indicated on the Notice of Stock Option Grant, Optionee shall
complete and execute the form of Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit B (the "Exercise Agreement").
Notwithstanding the foregoing, the Company may in its discretion prescribe or
accept a different form of notice of exercise and/or stock purchase agreement if
such forms are otherwise consistent with this Agreement, the Plan and
then-applicable law.

                  (ii) This Option may not be exercised for a fraction of a
share.

                  (iii) In the event of Optionee's death, disability or other
cessation of service as a director, the exercisability of the Option is governed
by Sections 5, 6 and 7 below, subject to the limitation contained in Section
2(a)(iv) below.

                  (iv) In no event may this Option be exercised after the
Expiration Date of this Option as set forth in the Notice of Stock Option Grant.

            (b) METHOD OF EXERCISE. This Option shall be exercisable by
execution and delivery of the Early Exercise Agreement or the Exercise
Agreement, whichever is applicable, or of any other written notice approved for
such purpose by the Company which shall state the election to exercise the
Option, the number of Shares in respect of which the Option is being exercised,
and such other representations and agreements as to the holder's investment
intent with respect to such shares of Common Stock as may be required by the
Company pursuant to the provisions of the Plan. Such written notice shall be

<PAGE>

signed by Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company. The written notice shall be accompanied by payment of
the Exercise Price. This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

      No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of
applicable law, including the requirements of any stock exchange upon which the
Shares may then be listed. Assuming such compliance, for income tax purposes the
Shares shall be considered transferred to Optionee on the date on which the
Option is exercised with respect to such Shares.

      3. METHOD OF PAYMENT. Payment of the Exercise Price shall be by cash,
check, or any other form approved by the Company), or any other method permitted
under the Plan; provided however that the Administrator may refuse to allow
Optionee to tender a particular form of payment (other than cash or check) if,
in the Administrator's sole discretion, acceptance of such form of consideration
would not be in the best interests of the Company at such time.

      4. RESTRICTIONS ON EXERCISE. This Option may not be exercised until such
time as the Plan has been approved by the shareholders of the Company, or if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board. As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

      5. CESSATION OF SERVICE OF THE DIRECTOR RELATIONSHIP. In the event that
the Optionee ceases to serve a director of the Company, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
Date"), exercise this Option during the Termination Period set forth in the
Notice of Stock Option Grant. To the extent that Optionee was not entitled to
exercise this Option at such Termination Date, or if Optionee does not exercise
this Option within the Termination Period, the Option shall terminate.

      6. DISABILITY OF OPTIONEE.

            (a) Notwithstanding the provisions of Section 5 above, in the event
that the Optionee ceases to serve a director of the Company as a result of his
or her total and permanent disability (as defined in Section 22(e)(3) of the
Code), Optionee may exercise this Option to the extent he or she was entitled to
exercise it at such Termination Date during the Termination Period. To the
extent that Optionee was not entitled to exercise the Option on the Termination
Date, or if Optionee does not exercise such Option to the extent so entitled
within the time specified in this Section 6(a), the Option shall terminate.

            (b) Notwithstanding the provisions of Section 5 above, in the event
that the Optionee ceases to serve a director of the Company as a result of a
disability not constituting a total and permanent disability (as set forth in
Section 22(e)(3) of the Code), Optionee may exercise the Option to the extent
Optionee was entitled to exercise it as of such Termination Date during the
Termination Period; provided, however, that if this is an Incentive Stock Option
and Optionee fails to exercise this Incentive Stock Option within three months
from the Termination Date, this Option will cease to qualify as an Incentive

                                       2
<PAGE>

Stock Option (as defined in Section 422 of the Code) and Optionee will be
treated for federal income tax purposes as having received ordinary income at
the time of such exercise in an amount generally measured by the difference
between the Exercise Price for the Shares and the Fair Market Value of the
Shares on the date of exercise. To the extent that Optionee was not entitled to
exercise the Option at the Termination Date, or if Optionee does not exercise
such Option to the extent so entitled within the time specified in this Section
6(b), the Option shall terminate.

      7. DEATH OF OPTIONEE. In the event of the death of Optionee (a) during the
Term of this Option and while the Optionee was in Continuous Status as a
Director of the Company since the date of grant of the Option, or (b) within 30
days after the Optionee ceased to serve a director of the Company, the Option
may be exercised at any time within as set forth in the Notice of Stock Option
Grant and in Section 9 below), by Optionee's estate or by a person who acquired
the right to exercise the Option by bequest or inheritance, but only to the
extent of the right to exercise that had accrued at the Termination Date.

      8. NON-TRANSFERABILITY OF OPTION. This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by him or her. The terms
of this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of Optionee.

      9. TERM OF OPTION. This Option may be exercised only within the Term set
forth in the Notice of Stock Option Grant, subject to the limitations set forth
in Section 7 of the Plan.

      10. TAX CONSEQUENCES. Set forth below is a brief summary as of the date of
this Option of certain of the federal and California tax consequences of
exercise of this Option and disposition of the Shares under the laws in effect
as of the Date of Grant. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX
LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

            (a) EXERCISE OF INCENTIVE STOCK OPTION. If this Option qualifies as
an Incentive Stock Option, there will be no regular federal or California income
tax liability upon the exercise of the Option, although the excess, if any, of
the Fair Market Value of the Shares on the date of exercise over the Exercise
Price will be treated as an adjustment to the alternative minimum tax for
federal tax purposes and may subject Optionee to the alternative minimum tax in
the year of exercise.

            (b) EXERCISE OF NONSTATUTORY STOCK OPTION. If this Option does not
qualify as an Incentive Stock Option, there may be a regular federal income tax
liability and a California income tax liability upon the exercise of the Option.
Optionee will be treated as having received compensation income (taxable at
ordinary income tax rates) equal to the excess, if any, of the fair market value
of the Shares on the date of exercise over the Exercise Price. If Optionee is a
current or former employee, the Company may be required to withhold from
Optionee's compensation or collect from Optionee and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

            (c) DISPOSITION OF SHARES. In the case of a Nonstatutory Stock
Option, if Shares are held for more than one year, any gain realized on
disposition of the Shares will be treated as long-term capital gain for federal
and California income tax purposes. In the case of an Incentive Stock Option, if

                                       3
<PAGE>

Shares transferred pursuant to the Option are held for more than one year after
exercise and are disposed of at least two years after the Date of Grant, any
gain realized on disposition of the Shares will also be treated as long-term
capital gain for federal and California income tax purposes. In either case, the
long-term capital gain will be taxed for federal income tax and alternative
minimum tax purposes at a maximum rate of 20% if the Shares are held more than
one year after exercise. If Shares purchased under an Incentive Stock Option are
disposed of within one year after exercise or within two years after the Date of
Grant, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the difference
between the Exercise Price and the lesser of (i) the Fair Market Value of the
Shares on the date of exercise, or (ii) the sale price of the Shares.

            (d) NOTICE OF DISQUALIFYING DISPOSITION OF INCENTIVE STOCK OPTION
SHARES. If the Option granted to Optionee herein is an Incentive Stock Option,
and if Optionee sells or otherwise disposes of any of the Shares acquired
pursuant to the Incentive Stock Option on or before the later of (i) the date
two years after the Date of Grant, or (ii) the date one year after the date of
exercise, Optionee shall immediately notify the Company in writing of such
disposition. Optionee acknowledges and agrees that he or she may be subject to
income tax withholding by the Company on the compensation income recognized by
Optionee from the early disposition by payment in cash or out of the current
earnings paid to Optionee.

      11. WITHHOLDING TAX OBLIGATIONS.

            (a) GENERAL WITHHOLDING OBLIGATIONS. As a condition to the exercise
of Option granted hereunder, Optionee shall make such arrangements as the
Administrator may require for the satisfaction of any federal, state, local or
foreign withholding tax obligations that may arise in connection with the
exercise, receipt or vesting of the Option. The Company shall not be required to
issue any Shares under the Plan until such obligations are satisfied. Optionee
understands that, upon exercising a Nonstatutory Stock Option, he or she will
recognize income for tax purposes in an amount equal to the excess of the then
Fair Market Value of the Shares over the Exercise Price. If Optionee is an
employee, the Company will be required to withhold from Optionee's compensation,
or collect from Optionee and pay to the applicable taxing authorities an amount
equal to a percentage of this compensation income. Additionally, Optionee may at
some point be required to satisfy tax withholding obligations with respect to
the disqualifying disposition of an Incentive Stock Option. Optionee shall
satisfy his or her tax withholding obligation arising upon the exercise of this
Option by one or some combination of the following methods: (i) by cash or check
payment, (ii) out of Optionee's current compensation, (iii) if permitted by the
Administrator, in its discretion, by surrendering to the Company Shares which
(A) in the case of Shares previously acquired from the Company, have been owned
by Optionee for more than six months on the date of surrender, and (B) have a
Fair Market Value determined as of the applicable Tax Date (as defined in
Section 11(c) below) on the date of surrender equal to the amount required to be
withheld, or (iv) by electing to have the Company withhold from the Shares to be
issued upon exercise of the Option, or the Shares to be issued in connection
with the Stock Purchase Right, if any, that number of Shares having a Fair
Market Value determined as of the applicable Tax Date equal to the amount
required to be withheld.

            (b) STOCK WITHHOLDING TO SATISFY WITHHOLDING TAX OBLIGATIONS. In the
event the Administrator allows Optionee to satisfy his or her tax withholding
obligations as provided in Section 11(a)(iii) or (iv) above, such satisfaction
must comply with the requirements of this Section (11)(b) and all applicable
laws. All elections by Optionee to have Shares withheld to satisfy tax
withholding obligations shall be made in writing in a form acceptable to the
Administrator and shall be subject to the following restrictions:

                                       4
<PAGE>

                  (i) the election must be made on or prior to the applicable
Tax Date (as defined in Section 11(c) below);

                  (ii) once made, the election shall be irrevocable as to the
particular Shares of the Option as to which the election is made; and

                  (iii) all elections shall be subject to the consent or
disapproval of the Administrator.

      In the event the election to have Shares withheld is made by Optionee and
the Tax Date is deferred under Section 83 of the Code because no election is
filed under Section 83(b) of the Code, Optionee shall receive the full number of
Shares with respect to which the Option is exercised but Optionee shall be
unconditionally obligated to tender back to the Company the proper number of
Shares on the Tax Date.

            (c) DEFINITIONS. For purposes of this Section 11, the Fair Market
Value of the Shares to be withheld shall be determined on the date that the
amount of tax to be withheld is to be determined under the Applicable Laws (the
"Tax Date").

      12. MARKET STANDOFF AGREEMENT. In connection with any public offering of
the Company's securities and upon request of the Company or the underwriters
managing such underwritten offering of the Company's securities, Optionee agrees
not to sell, make any short sale of, loan, grant any option for the purchase of,
or otherwise dispose of any securities of the Company (other than those included
in the registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed 180
days) from the effective date of such registration as may be requested by the
Company or such managing underwriters and to execute an agreement reflecting the
foregoing as may be requested by the underwriters at the time of the Company's
public offering.

          EARLY EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT

      This Agreement ("Agreement") is made as of __________________________, by
and between World Waste Technologies, Inc., a California corporation (the

Agreement dated _________________ (the "Option Agreement"). Of these Shares,
Purchaser has elected to purchase _________________ of those Shares which have
become vested as of the date hereof under the Vesting Schedule set forth in the
Notice of Stock Option Grant (the "Vested Shares") and ____________ Shares which
have not yet vested under such Vesting Schedule (the "Unvested Shares"). The

and all securities received in replacement of the Shares or as stock dividends
or splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

      2. TIME AND PLACE OF EXERCISE. The purchase and sale of the Shares under
this Agreement shall occur at the principal office of the Company simultaneously
with the execution and delivery of this Agreement in accordance with the
provisions of Section 2(b) of the Option Agreement. On such date, the Company
will deliver to Purchaser a certificate representing the Shares to be purchased
by Purchaser (which shall be issued in Purchaser's name) against payment of the
purchase price therefor by Purchaser by (a) check made payable to the Company,
(b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of
shares of the Common Stock of the Company in accordance with Section 3 of the
Option Agreement, or (d) a combination of the foregoing.

      3. LIMITATIONS ON TRANSFER. In addition to any other limitation on
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below). After any Shares have
been released from such Repurchase Option, Purchaser shall not assign, encumber
or dispose of any interest in such Shares except in compliance with the
provisions below and applicable securities laws.

            (a) REPURCHASE OPTION.

                  (i) In the event that the Purchaser ceases to serve a director
of the Company for any reason (including death or disability) the Company shall
upon the date of such cessation of service (the "Termination Date") have an
irrevocable, exclusive option (the "Repurchase Option") for a period of 90 days
from such date to repurchase all or any portion of the Shares held by Purchaser
as of the Termination Date which have not yet been released from the Company's
Repurchase Option at the original purchase price per Share specified in Section
1 (adjusted for any stock splits, stock dividends and the like).

                                      A-1
<PAGE>

                  (ii) Unless the Company notifies Purchaser within 90 days from
the date of cessation of Purchaser's service as a director that it does not
intend to exercise its Repurchase Option with respect to some or all of the
Shares, the Repurchase Option shall be deemed automatically exercised by the
Company as of the 90th day following such cessation of service, provided that
the Company may notify Purchaser that it is exercising its Repurchase Option as
of a date prior to such 90th day. Unless Purchaser is otherwise notified by the
Company pursuant to the preceding sentence that the Company does not intend to
exercise its Repurchase Option as to some or all of the Shares to which it
applies at the time of cessation of service, execution of this Agreement by
Purchaser constitutes written notice to Purchaser of the Company's intention to
exercise its Repurchase Option with respect to all Shares to which such
Repurchase Option applies. The Company, at its choice, may satisfy its payment
obligation to Purchaser with respect to exercise of the Repurchase Option by
either (A) delivering a check to Purchaser in the amount of the purchase price
for the Shares being repurchased, or (B) in the event Purchaser is indebted to
the Company, canceling an amount of such indebtedness equal to the purchase
price for the Shares being repurchased, or (C) by a combination of (A) and (B)
so that the combined payment and cancellation of indebtedness equals such
purchase price. In the event of any deemed automatic exercise of the Repurchase
Option pursuant to this Section 3(a)(ii) in which Purchaser is indebted to the
Company, such indebtedness equal to the purchase price of the Shares being
repurchased shall be deemed automatically canceled as of the 90th day following
the cessation of Purchaser's service as a director unless the Company otherwise
satisfies its payment obligations. As a result of any repurchase of Shares
pursuant to this Section 3(a), the Company shall become the legal and beneficial
owner of the Shares being repurchased and shall have all rights and interest
therein or related thereto, and the Company shall have the right to transfer to
its own name the number of Shares being repurchased by the Company, without
further action by Purchaser.

                  (iii) One hundred percent (100%) of the Shares shall initially
be subject to the Repurchase Option. The Unvested Shares shall be released from
the Repurchase Option in accordance with the Vesting Schedule set forth in the
Notice of Stock Option Grant until all Shares are released from the Repurchase
Option. Fractional shares shall be rounded to the nearest whole share.

                  (iv) Change in Control. All Unvested Shares shall be released
from the Repurchase Option in full and immediately become exercisable in full
upon a Change in Control (as defined herein). For purposes hereof, "Change in
Control" means an event or occurrence set forth in any one or more of
subsections (a) through (d) below (including an event or occurrence that
constitutes a Change in Control under one of such subsections but is
specifically exempted from another such subsection):

                        (1) the acquisition by an individual, entity or group
(within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange
Act of 1934, as amended (the "Exchange Act")) (a "Person") of beneficial
ownership of any capital stock of the Company if, after such acquisition, such
Person beneficially owns (within the meaning of Rule 13d-3 promulgated under the
Exchange Act) a majority or more of either (i) the then outstanding shares of
common stock of the Company (the "Outstanding Company Common Stock") or (ii) the
combined voting power of the then outstanding securities of the Company entitled
to vote generally in the election of directors (the "Outstanding Company Voting
Securities"); provided, however, that for purposes of this subsection (a), the
following acquisitions shall not constitute a Change in Control: (i) any
acquisition directly from the Company (excluding an acquisition pursuant to the

                                      A-2
<PAGE>

exercise, conversion or exchange of any security exercisable for, convertible
into or exchangeable for common stock or voting securities of the Company,
unless the Person exercising, converting or exchanging such security acquired
such security directly from the Company or an underwriter or agent of the
Company), (ii) any acquisition by the Company, (iii) any acquisition by any
employee benefit plan (or related trust) sponsored or maintained by the Company
or any corporation controlled by the Company, or (iv) any Business Combination
(as defined below) excepted from subsection (c) of this Section 3 by the proviso
set forth therein; or

                        (2) such time as the Continuing Directors (as defined
below) do not constitute a majority of the Board (or, if applicable, the Board
of Directors of a successor corporation to the Company), where the term
"Continuing Director" means at any date a member of the Board (i) who was a
member of the Board on the date of adoption of the Plan or (ii) who was
nominated or elected subsequent to such date by at least a majority of the
directors who were Continuing Directors at the time of such nomination or
election or whose election to the Board was recommended or endorsed by at least
a majority of the directors who were Continuing Directors at the time of such
nomination or election; provided, however, that there shall be excluded from
this clause (ii) any individual whose initial assumption of office occurred as a
result of an actual or threatened election contest with respect to the election
or removal of directors or other actual or threatened solicitation of proxies or
consents, by or on behalf of a person other than the Board; or

                        (3) the consummation of a merger, consolidation,
reorganization, recapitalization or statutory share exchange involving the
Company or a sale or other disposition of all or substantially all of the assets
of the Company (a "Business Combination"), provided, that no such Business
Combination shall constitute a Change in Control if, immediately following such
Business Combination, all or substantially all of the individuals and entities
who were the beneficial owners of the Outstanding Company Common Stock and
Outstanding Company Voting Securities immediately prior to such Business
Combination beneficially own, directly or indirectly, at least a majority of the
then outstanding shares of common stock and the combined voting power of the
then outstanding securities entitled to vote generally in the election of
directors, respectively, of the resulting or acquiring corporation in such
Business Combination (which shall include, without limitation, a corporation
which as a result of such transaction owns the Company or substantially all of
the Company's assets either directly or through one or more subsidiaries) in
substantially the same proportions as their ownership, immediately prior to such
Business Combination, of the Outstanding Company Common Stock and Outstanding
Company Voting Securities, respectively; or

                        (4) approval by the stockholders of the Company of a
complete liquidation or dissolution of the Company.

            (b) RIGHT OF FIRST REFUSAL. Before any Shares held by Purchaser or
any transferee of Purchaser (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(b) (the "Right of First Refusal").

                  (i) NOTICE OF PROPOSED TRANSFER. The Holder of the Shares
shall deliver to the Company a written notice (the "Notice") stating: (i) the
Holder's bona fide intention to sell or otherwise transfer such Shares; (ii) the

                                      A-3
<PAGE>

name of each proposed purchaser or other transferee ("Proposed Transferee");
(iii) the number of Shares to be transferred to each Proposed Transferee; and
(iv) the terms and conditions of each proposed sale or transfer. The Holder
shall offer the Shares at the same price (the "Offered Price") and upon the same
terms (or terms as similar as reasonably possible) to the Company or its
assignee(s).

                  (ii) EXERCISE OF RIGHT OF FIRST REFUSAL. At any time within 30
days after receipt of the Notice, the Company and/or its assignee(s) may, by
giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection
(iii) below.

                  (iii) PURCHASE PRICE. The purchase price ("Purchase Price")
for the Shares purchased by the Company or its assignee(s) under this Section
3(b) shall be the Offered Price. If the Offered Price includes consideration
other than cash, the cash equivalent value of the non-cash consideration shall
be determined by the Board of Directors of the Company in good faith.

                  (iv) PAYMENT. Payment of the Purchase Price shall be made, at
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

                  (v) HOLDER'S RIGHT TO TRANSFER. If all of the Shares proposed
in the Notice to be transferred to a given Proposed Transferee are not purchased
by the Company and/or its assignee(s) as provided in this Section 3(b), then the
Holder may sell or otherwise transfer such Shares to that Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 60 days after the date of the Notice and provided
further that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section 3 shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, or if the Holder
proposes to change the price or other terms to make them more favorable to the
Proposed Transferee, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

                  (vi) EXCEPTION FOR CERTAIN FAMILY TRANSFERS. Anything to the
contrary contained in this Section 3(b) notwithstanding, the transfer of any or
all of the Shares during Purchaser's lifetime or on Purchaser's death by will or
intestacy to Purchaser's Immediate Family (as defined below) or a trust for the
benefit of Purchaser's Immediate Family shall be exempt from the provisions of
this Section 3(b). "Immediate Family" as used herein shall mean spouse, lineal
descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Section, and there shall be no further
transfer of such Shares except in accordance with the terms of this Section 3.

            (c) INVOLUNTARY TRANSFER.

                                      A-4
<PAGE>

                  (i) COMPANY'S RIGHT TO PURCHASE UPON INVOLUNTARY TRANSFER. In
the event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including divorce or death, but
excluding, in the event of death, a transfer to Immediate Family as set forth in
Section 3(b)(vi) above) of all or a portion of the Shares by the record holder
thereof, the Company shall have the right to purchase all of the Shares
transferred at the greater of the purchase price paid by Purchaser pursuant to
this Agreement or the Fair Market Value of the Shares on the date of transfer.
Upon such a transfer, the person acquiring the Shares shall promptly notify the
Secretary of the Company of such transfer. The right to purchase such Shares
shall be provided to the Company for a period of 30 days following receipt by
the Company of written notice by the person acquiring the Shares.

                  (ii) PRICE FOR INVOLUNTARY TRANSFER. With respect to any stock
to be transferred pursuant to Section 3(c)(i), the price per Share shall be a
price set by the Board of Directors of the Company that will reflect the current
value of the stock in terms of present earnings and future prospects of the
Company. The Company shall notify Purchaser or his or her executor of the price
so determined within 30 days after receipt by it of written notice of the
transfer or proposed transfer of Shares. However, if the Purchaser does not
agree with the valuation as determined by the Board of Directors of the Company,
the Purchaser shall be entitled to have the valuation determined by an
independent appraiser to be mutually agreed upon by the Company and the
Purchaser and whose fees shall be borne equally by the Company and the
Purchaser.

            (d) ASSIGNMENT. The right of the Company to purchase any part of the
Shares may be assigned in whole or in part to any shareholder or shareholders of
the Company or other persons or organizations.

            (e) RESTRICTIONS BINDING ON TRANSFEREES. All transferees of Shares
or any interest therein will receive and hold such Shares or interest subject to
the provisions of this Agreement, including, insofar as applicable, the
Repurchase Option. In the event of any purchase by the Company hereunder where
the Shares or interest are held by a transferee, the transferee shall be
obligated, if requested by the Company, to transfer the Shares or interest to
the Purchaser for consideration equal to the amount to be paid by the Company
hereunder. In the event the Repurchase Option is deemed exercised by the Company
pursuant to Section 3(a)(ii) hereof, the Company may deem any transferee to have
transferred the Shares or interest to Purchaser prior to their purchase by the
Company, and payment of the purchase price by the Company to such transferee
shall be deemed to satisfy Purchaser's obligation to pay such transferee for
such Shares or interest, and also to satisfy the Company's obligation to pay
Purchaser for such Shares or interest. Any sale or transfer of the Shares shall
be void unless the provisions of this Agreement are satisfied.

            (f) TERMINATION OF RIGHTS. The Right of First Refusal and the
Company's right to repurchase the Shares in the event of an involuntary transfer
pursuant to Section 3(c) above shall terminate upon the listing of Common Stock
of the Company on a national exchange.

            (g) MARKET STANDOFF AGREEMENT. In connection with any public
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any securities of the Company (other
than those included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed 180 days) from the effective date of such registration as may be
requested by the Company or such managing underwriters and to execute an
agreement reflecting the foregoing as may be requested by the underwriters at
the time of the Company's public offering.

                                      A-5
<PAGE>

      4. ESCROW OF UNVESTED SHARES. For purposes of facilitating the enforcement
of the provisions of Section 3 above, Purchaser agrees, immediately upon receipt
of the certificate(s) for the Shares subject to the Repurchase Option, to
deliver such certificate(s), together with an Assignment Separate from
Certificate in the form attached to this Agreement as Attachment A executed by
Purchaser and by Purchaser's spouse (if required for transfer), in blank, to the
Secretary of the Company, or the Secretary's designee, to hold such
certificate(s) and Assignment Separate from Certificate in escrow and to take
all such actions and to effectuate all such transfers and/or releases as are in
accordance with the terms of this Agreement. Purchaser hereby acknowledges that
the Secretary of the Company, or the Secretary's designee, is so appointed as
the escrow holder with the foregoing authorities as a material inducement to
make this Agreement and that said appointment is coupled with an interest and is
accordingly irrevocable. Purchaser agrees that said escrow holder shall not be
liable to any party hereof (or to any other party). The escrow holder may rely
upon any letter, notice or other document executed by any signature purported to
be genuine and may resign at any time. Purchaser agrees that if the Secretary of
the Company, or the Secretary's designee, resigns as escrow holder for any or no
reason, the Board of Directors of the Company shall have the power to appoint a
successor to serve as escrow holder pursuant to the terms of this Agreement.

      5. INVESTMENT AND TAXATION REPRESENTATIONS. In connection with the
purchase of the Shares, Purchaser represents to the Company the following:

            (a) Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Shares. Purchaser is
purchasing the Shares for investment for his or her own account only and not
with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act. Purchaser does not have any present
intention to transfer the Shares to any other person or entity.

            (b) Purchaser understands that the Shares have not been registered
under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.

            (c) Purchaser understands that the Shares are "restricted
securities" under applicable U.S. federal and state securities laws and that,
pursuant to these laws, Purchaser must hold the Shares indefinitely unless they
are registered with the Securities and Exchange Commission and qualified by
state authorities, or an exemption from such registration and qualification
requirements is available. Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale. Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

            (d) Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection with the purchase or disposition of the Shares and
that Purchaser is not relying on the Company for any tax advice.

                                      A-6
<PAGE>

      6. RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

            (a) LEGENDS. The certificate or certificates representing the Shares
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

                  (i) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR
INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN
EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A
FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER
THE SECURITIES ACT OF 1933.

                  (ii) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE
TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE
COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF
THE COMPANY.

            (b) STOP-TRANSFER NOTICES. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

            (c) REFUSAL TO TRANSFER. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

            (d) REMOVAL OF LEGEND. When all of the following events have
occurred, the Shares then held by Purchaser will no longer be subject to the
legend referred to in Section 6(a)(ii): (i) the termination of the Right of
First Refusal; (ii) the expiration or termination of the market standoff
provisions of Section 3(g) (and of any agreement entered pursuant to Section
3(g)); and (iii) the expiration or exercise in full of the Repurchase Option.
After such time, and upon Purchaser's request, a new certificate or certificates
representing the Shares not repurchased shall be issued without the legend
referred to in Section 6(a)(ii), and delivered to Purchaser.

      7. NO RETENTION RIGHTS. Nothing in this Agreement or the Plan shall
constitute evidence of any agreement or understanding, express or implied, that
the Company will retain the Purchaser as a director for any period of time.

      8. SECTION 83(B) ELECTION. Purchaser understands that Section 83(a) of the
Internal Revenue Code of 1986, as amended (the "Code"), taxes as ordinary income
for a Nonstatutory Stock Option and as alternative minimum taxable income for an
Incentive Stock Option the difference between the amount paid for the Shares and

                                      A-7
<PAGE>

the Fair Market Value of the Shares as of the date any restrictions on the
Shares lapse. In this context, "restriction" means the right of the Company to
buy back the Shares pursuant to the Repurchase Option set forth in Section 3(a)
of this Agreement. Purchaser understands that Purchaser may elect to be taxed at
the time the Shares are purchased, rather than when and as the Repurchase Option
expires, by filing an election under Section 83(b) (an "83(b) Election") of the
Code with the Internal Revenue Service within 30 days from the date of purchase.
Even if the Fair Market Value of the Shares at the time of the execution of this
Agreement equals the amount paid for the Shares, the election must be made to
avoid income and alternative minimum tax treatment under Section 83(a) in the
future. Purchaser understands that failure to file such an election in a timely
manner may result in adverse tax consequences for Purchaser. Purchaser further
understands that an additional copy of such election form should be filed with
his or her federal income tax return for the calendar year in which the date of
this Agreement falls. Purchaser acknowledges that the foregoing is only a
summary of the effect of United States federal income taxation with respect to
purchase of the Shares hereunder, and does not purport to be complete. Purchaser
further acknowledges that the Company has directed Purchaser to seek independent
advice regarding the applicable provisions of the Code, the income tax laws of
any municipality, state or foreign country in which Purchaser may reside, and
the tax consequences of Purchaser's death.

      Purchaser agrees that he or she will execute and deliver to the Company
with this executed Agreement a copy of the Acknowledgment and Statement of
Decision Regarding Section 83(b) Election (the "Acknowledgment") attached hereto
as Attachment B. Purchaser further agrees that he or she will execute and submit
with the Acknowledgment a copy of the 83(b) Election attached hereto as
Attachment C (for tax purposes in connection with the early exercise of an
option) if Purchaser has indicated in the Acknowledgment his or her decision to
make such an election.

      9. MISCELLANEOUS.

            (a) GOVERNING LAW. This Agreement and all acts and transactions
pursuant hereto and the rights and obligations of the parties hereto shall be

modification of or amendment to this Agreement, nor any waiver of any rights
under this Agreement, shall be effective unless in writing signed by the parties
to this Agreement. The failure by either party to enforce any rights under this
Agreement shall not be construed as a waiver of any rights of such party.

            (c) SEVERABILITY. If one or more provisions of this Agreement are
held to be unenforceable under applicable law, the parties agree to renegotiate
such provision in good faith. In the event that the parties cannot reach a
mutually agreeable and enforceable replacement for such provision, then (i) such
provision shall be excluded from this Agreement, (ii) the balance of the
Agreement shall be interpreted as if such provision were so excluded and (iii)
the balance of the Agreement shall be enforceable in accordance with its terms.

                                 2004 STOCK PLAN
             EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT

      This Agreement ("Agreement") is made as of ______________, by and between
World Waste Technologies, Inc., a California corporation (the "Company"), and
____________ ("Purchaser"). To the extent any capitalized terms used in this
Agreement are not defined, they shall have the meaning ascribed to them in the
2004 STOCK PLAN.

      1. EXERCISE OF OPTION. Subject to the terms and conditions hereof,
Purchaser hereby elects to exercise his or her option to purchase __________
shares of the Common Stock (the "Shares") of the Company under and pursuant to
the Company's 2004 STOCK PLAN (the "Plan") and the Stock Option Agreement dated
______________, (the "Option Agreement"). The purchase price for the Shares
shall be $__________per Share for a total purchase price of $_______________.
The term "Shares" refers to the purchased Shares and all securities received in
replacement of the Shares or as stock dividends or splits, all securities
received in replacement of the Shares in a recapitalization, merger,
reorganization, exchange or the like, and all new, substituted or additional
securities or other properties to which Purchaser is entitled by reason of
Purchaser's ownership of the Shares.

      2. TIME AND PLACE OF EXERCISE. The purchase and sale of the Shares under
this Agreement shall occur at the principal office of the Company simultaneously
with the execution and delivery of this Agreement in accordance with the
provisions of Section 2(b) of the Option Agreement. On such date, the Company
will deliver to Purchaser a certificate representing the Shares to be purchased
by Purchaser (which shall be issued in Purchaser's name) against payment of the
purchase price therefor by Purchaser by (a) check made payable to the Company,
(b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of
shares of the Common Stock of the Company in accordance with Section 3 of the
Option Agreement, or (d) a combination of the foregoing.

      3. LIMITATIONS ON TRANSFER. In addition to any other limitation on
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares except in compliance with the
provisions below and applicable securities laws.

            (a) RIGHT OF FIRST REFUSAL. Before any Shares held by Purchaser or
any transferee of Purchaser (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section 3(a) (the "Right of First Refusal").

                  (i) NOTICE OF PROPOSED TRANSFER. The Holder of the Shares
shall deliver to the Company a written notice (the "Notice") stating: (i) the
Holder's bona fide intention to sell or otherwise transfer such Shares; (ii) the
name of each proposed purchaser or other transferee ("Proposed Transferee");
(iii) the number of Shares to be transferred to each Proposed Transferee; and
(iv) the terms and conditions of each proposed sale or transfer. The Holder
shall offer the Shares at the same price (the "Offered Price") and upon the same
terms (or terms as similar as reasonably possible) to the Company or its
assignee(s).

                                      B-1
<PAGE>

                  (ii) EXERCISE OF RIGHT OF FIRST REFUSAL. At any time within 30
days after receipt of the Notice, the Company and/or its assignee(s) may, by
giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection
(iii) below.

                  (iii) PURCHASE PRICE. The purchase price ("Purchase Price")
for the Shares purchased by the Company or its assignee(s) under this Section
3(a) shall be the Offered Price. If the Offered Price includes consideration
other than cash, the cash equivalent value of the non-cash consideration shall
be determined by the Board of Directors of the Company in good faith.

                  (iv) PAYMENT. Payment of the Purchase Price shall be made, at
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

                  (v) HOLDER'S RIGHT TO TRANSFER. If all of the Shares proposed
in the Notice to be transferred to a given Proposed Transferee are not purchased
by the Company and/or its assignee(s) as provided in this Section 3(a), then the
Holder may sell or otherwise transfer such Shares to that Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 60 days after the date of the Notice and provided
further that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section 3 shall continue to apply to the Shares in the
hands of such Proposed Transferee. If the Shares described in the Notice are not
transferred to the Proposed Transferee within such period, or if the Holder
proposes to change the price or other terms to make them more favorable to the
Proposed Transferee, a new Notice shall be given to the Company, and the Company
and/or its assignees shall again be offered the Right of First Refusal before
any Shares held by the Holder may be sold or otherwise transferred.

                  (vi) EXCEPTION FOR CERTAIN FAMILY TRANSFERS. Anything to the
contrary contained in this Section 3(a) notwithstanding, the transfer of any or
all of the Shares during Purchaser's lifetime or on Purchaser's death by will or
intestacy to Purchaser's Immediate Family (as defined below) or a trust for the
benefit of Purchaser's Immediate Family shall be exempt from the provisions of
this Section 3(a). "Immediate Family" as used herein shall mean spouse, lineal
descendant or antecedent, father, mother, brother or sister. In such case, the
transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Section, and there shall be no further
transfer of such Shares except in accordance with the terms of this Section 3.

            (b) INVOLUNTARY TRANSFER.

                  (i) COMPANY'S RIGHT TO PURCHASE UPON INVOLUNTARY TRANSFER. In
the event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including divorce or death, but
excluding, in the event of death, a transfer to Immediate Family as set forth in

                                      B-2
<PAGE>

Section 3(a)(vi) above) of all or a portion of the Shares by the record holder
thereof, the Company shall have the right to purchase all of the Shares
transferred at the greater of the purchase price paid by Purchaser pursuant to
this Agreement or the Fair Market Value of the Shares on the date of transfer.
Upon such a transfer, the person acquiring the Shares shall promptly notify the
Secretary of the Company of such transfer. The right to purchase such Shares
shall be provided to the Company for a period of 30 days following receipt by
the Company of written notice by the person acquiring the Shares.

                  (ii) PRICE FOR INVOLUNTARY TRANSFER. With respect to any stock
to be transferred pursuant to Section 3(b)(i), the price per Share shall be a
price set by the Board of Directors of the Company that will reflect the current
value of the stock in terms of present earnings and future prospects of the
Company. The Company shall notify Purchaser or his or her executor of the price
so determined within 30 days after receipt by it of written notice of the
transfer or proposed transfer of Shares. However, if the Purchaser does not
agree with the valuation as determined by the Board of Directors of the Company,
the Purchaser shall be entitled to have the valuation determined by an
independent appraiser to be mutually agreed upon by the Company and the
Purchaser and whose fees shall be borne equally by the Company and the
Purchaser.

            (c) ASSIGNMENT. The right of the Company to purchase any part of the
Shares may be assigned in whole or in part to any shareholder or shareholders of
the Company or other persons or organizations.

            (d) RESTRICTIONS BINDING ON TRANSFEREES. All transferees of Shares
or any interest therein will receive and hold such Shares or interest subject to
the provisions of this Agreement. Any sale or transfer of the Shares shall be
void unless the provisions of this Agreement are satisfied.

            (e) TERMINATION OF RIGHTS. The Right of First Refusal and the
Company's right to repurchase the Shares in the event of an involuntary transfer
pursuant to Section 3(b) above shall terminate upon the listing of Common Stock
of the Company on a national exchange.

            (f) MARKET STANDOFF AGREEMENT. In connection with any public
offering of the Company's securities and upon request of the Company or the
underwriters managing such underwritten offering of the Company's securities,
Purchaser agrees not to sell, make any short sale of, loan, grant any option for
the purchase of, or otherwise dispose of any securities of the Company (other
than those included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed 180 days) from the effective date of such registration as may be
requested by the Company or such managing underwriters and to execute an
agreement reflecting the foregoing as may be requested by the underwriters at
the time of the Company's public offering.

      4. INVESTMENT AND TAXATION REPRESENTATIONS. In connection with the
purchase of the Shares, Purchaser represents to the Company the following:

            (a) Purchaser is aware of the Company's business affairs and
financial condition and has acquired sufficient information about the Company to
reach an informed and knowledgeable decision to acquire the Shares. Purchaser is
purchasing the Shares for investment for his or her own account only and not
with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act.

                                      B-3
<PAGE>

            (b) Purchaser understands that the Shares have not been registered
under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.

            (c) Purchaser understands that the Shares are "restricted
securities" under applicable U.S. federal and state securities laws and that,
pursuant to these laws, Purchaser must hold the Shares indefinitely unless they
are registered with the Securities and Exchange Commission and qualified by
state authorities, or an exemption from such registration and qualification
requirements is available. Purchaser acknowledges that the Company has no
obligation to register or qualify the Shares for resale. Purchaser further
acknowledges that if an exemption from registration or qualification is
available, it may be conditioned on various requirements including, but not
limited to, the time and manner of sale, the holding period for the Shares, and
requirements relating to the Company which are outside of the Purchaser's
control, and which the Company is under no obligation and may not be able to
satisfy.

            (d) Purchaser understands that Purchaser may suffer adverse tax
consequences as a result of Purchaser's purchase or disposition of the Shares.
Purchaser represents that Purchaser has consulted any tax consultants Purchaser
deems advisable in connection with the purchase or disposition of the Shares and
that Purchaser is not relying on the Company for any tax advice.

      5. RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

            (a) LEGENDS. The certificate or certificates representing the Shares
shall bear the following legends (as well as any legends required by applicable
state and federal corporate and securities laws):

                  (i) THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR
INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN
EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A
FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER
THE SECURITIES ACT OF 1933.

                  (ii) THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE
TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE
COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF
THE COMPANY.

            (b) STOP-TRANSFER NOTICES. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

            (c) REFUSAL TO TRANSFER. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

                                      B-4
<PAGE>

            (d) REMOVAL OF LEGEND. When all of the following events have
occurred, the Shares then held by Purchaser will no longer be subject to the
legend referred to in Section 5(a)(ii): (i) the termination of the Right of
First Refusal; and (ii) the expiration or termination of the market standoff
provisions of Section 3(f) (and of any agreement entered pursuant to Section
3(f)). After such time, and upon Purchaser's request, a new certificate or
certificates representing the Shares not repurchased shall be issued without the
legend referred to in Section 5(a)(ii), and delivered to Purchaser.

      6. NO RETENTION RIGHTS. Nothing in this Agreement or the Plan shall
constitute evidence of any agreement or understanding, express or implied, that
the Company will retain the Purchaser as a director for any period of time.

      7. MISCELLANEOUS.

            (a) GOVERNING LAW. This Agreement and all acts and transactions
pursuant hereto and the rights and obligations of the parties hereto shall be

            (b) ENTIRE AGREEMENT; ENFORCEMENT OF RIGHTS. This Agreement sets

subject matter herein and merges all prior discussions between them. No
modification of or amendment to this Agreement, nor any waiver of any rights
under this Agreement, shall be effective unless in writing signed by the parties
to this Agreement. The failure by either party to enforce any rights under this
Agreement shall not be construed as a waiver of any rights of such party.

            (c) SEVERABILITY. If one or more provisions of this Agreement are
held to be unenforceable under applicable law, the parties agree to renegotiate
such provision in good faith. In the event that the parties cannot reach a
mutually agreeable and enforceable replacement for such provision, then (i) such
provision shall be excluded from this Agreement, (ii) the balance of the
Agreement shall be interpreted as if such provision were so excluded and (iii)
the balance of the Agreement shall be enforceable in accordance with its terms.

            (d) CONSTRUCTION. This Agreement is the result of negotiations
between and has been reviewed by each of the parties hereto and their respective
counsel, if any; accordingly, this Agreement shall be deemed to be the product
of all of the parties hereto, and no ambiguity shall be construed in favor of or
against any one of the parties hereto.

            (e) NOTICES. Any notice required or permitted by this Agreement
shall be in writing and shall be deemed sufficient when delivered personally or
sent by telegram or fax or 48 hours after being deposited in the U.S. mail, as

to be notified at such party's address as set forth below or as subsequently
modified by written notice.

            (f) COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument.

            (g) SUCCESSORS AND ASSIGNS. The rights and benefits of this
Agreement shall inure to the benefit of, and be enforceable by the Company's
successors and assigns. The rights and obligations of Purchaser under this
Agreement may only be assigned with the prior written consent of the Company.
