Exhibit 10.30

                                 BIDVILLE, INC.
                            2004 Stock Incentive Plan

1.    Purpose

      The purpose of this 2004 Stock  Incentive  Plan (the  "Plan") of Bidville,
Inc., a Nevada  corporation (the "Company"),  is to advance the interests of the
Company's stockholders by enhancing the Company's ability to attract, retain and
motivate  persons who make (or are expected to make) important  contributions to
the Company by providing such persons with equity  ownership  opportunities  and
performance-based  incentives and thereby better  aligning the interests of such
persons  with those of the  Company's  stockholders.  Except  where the  context
otherwise  requires,  the term  "Company"  shall  include  any of the  Company's
present or future  subsidiary  corporations  as defined in Section 424(f) of the
Internal  Revenue  Code  of1986,  as amended,  and any  regulations  promulgated
thereunder (the "Code").

2.    Eligibility

      All of  the  Company's  employees,  directors  and  consultants  (and  any
individuals  who have  accepted  an offer for  employment)  are  eligible  to be
granted options,  restricted stock awards, or other stock-based awards (each, an
"Award") as hereafter  provided in the Plan. Each person who has been granted an
Award under the Plan shall be deemed a "Participant".

3.    Administration, Delegation

      (a) Administration by Board of Directors. The Plan will be administered by
the Board of  Directors  of the  Company  (the  "Board").  The Board  shall have
authority to grant  Awards and  determine  the number of shares,  prices and all
other terms, conditions and restrictions pertaining to them, and to adopt, amend
and repeal such  administrative  rules,  guidelines  and  practices  relating to
Awards  and the Plan as it shall  deem  advisable.  The  Board may  correct  any
defect,  supply any omission or reconcile any  inconsistency  in the Plan or any
Award in the manner and to the extent it shall deem  expedient to carry the Plan
into effect,  and it shall be the sole and final judge of such  expediency.  All
decisions by the Board shall be made in the Board's sole discretion and shall be
final and binding on all  Participants  and other persons having or claiming any
interest in the Plan or in any Award.  No director or person acting  pursuant to
the  authority  delegated  by the  Board  shall  be  liable  for any  action  or
determination relating to or under the Plan made in good faith.

      (b)  Delegation  to  Executive  Officers.   To  the  extent  permitted  by
applicable law, the Board may delegate to one or more executive  officers of the
Company the power to make Awards and  exercise  such other powers under the Plan
as the Board may determine, provided that the Board shall fix the maximum number
of  shares  subject  to Awards  and the  maximum  number  of shares  for any one
Participant to be made by such executive officers.

                                       1
<PAGE>

      (c) Appointment of Committees.  To the extent permitted by applicable law,
the Board may  delegate  any or all of its powers  under the Plan to one or more
committees or subcommittees of the Board (a "Committee").  All references in the
Plan to the  "Board"  shall  mean the Board or a  Committee  of the Board or the
executive  officer  referred  to in Section  3(b) to the extent that the Board's
powers or  authority  under the Plan have been  delegated  to such  Committee or
executive officer.

4.    Stock Available for Awards

      Subject  to  adjustment  under  Section 8 of the Plan,  Awards may be made
under the Plan for up to seven  million  (7,000,000)  shares  of  common  stock,
$0.001 par value per share,  of the Company (the "Common  Stock").  If any Award
expires or is  terminated,  surrendered  or canceled  without  having been fully
exercised or is forfeited in whole or in part or results in any Common Stock not
being  issued,  the unused  Common  Stock  covered by such Award  shall again be
available for the grant of Awards under the Plan, subject,  however, in the case
of Incentive Stock Options (as hereinafter  defined), to any limitation required
under the Code.  Shares issued under the Plan may consist in whole or in part of
authorized but unissued shares or treasury shares.

5.    Stock Options

      (a) General.  The Board may grant options to purchase  Common Stock (each,
an "Option") and determine the number of shares of Common Stock to be covered by
each  Option,  the  exercise  price  of  each  Option  and  the  conditions  and
limitations  applicable  to the  exercise of each Option,  including  conditions
relating  to  applicable  federal  or state  securities  laws,  as it  considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as  hereinafter  defined)  shall be  designated  a  "Nonstatutory  Stock
Option".

      (b)  Incentive  Stock  Options.  An Option that the Board intends to be an
"incentive  stock  option" as defined in Section 422 of the Code (an  "Incentive
Stock  Option")  shall only be granted to  employees of the Company and shall be
subject to and shall be construed  consistently with the requirements of Section
422 of the Code.  The Company shall have no liability to a  Participant,  or any
other  party,  if an Option (or any part  thereof)  which is  intended  to be an
Incentive Stock Option is not an Incentive Stock Option.

      (c) Exercise  Price.  The Board shall  establish the exercise price at the
time each Option is granted and specify it in the applicable option agreement.

                                       2
<PAGE>

      (d) Duration of Options.  Each Option shall be  exercisable  at such times
and  subject  to such  terms and  conditions  as the Board  may  specify  in the
applicable option agreement.

      (e)  Exercise  of Option.  Options  may be  exercised  by  delivery to the
Company of a written  notice of exercise  signed by the proper  person or by any
other  form of  notice  (including  electronic  notice)  approved  by the  Board
together  with  payment in full as  specified  in Section 5(f) for the number of
shares for which the Option is exercised.

      (f) Payment Upon Exercise.  Common Stock purchased upon the exercise of an
Option granted under the Plan shall be paid for as follows:

            (1) in cash or by check, payable to the order of the Company;

            (2)  except  as the Board  may,  in its sole  discretion,  otherwise
provide  in  an  option  agreement,  by  (i)  delivery  of  an  irrevocable  and
unconditional  undertaking by a creditworthy  broker to deliver  promptly to the
Company  sufficient  funds to pay the  exercise  price or (ii)  delivery  by the
Participant  to  the  Company  of  a  copy  of  irrevocable  and   unconditional
instructions to a creditworthy broker to deliver promptly to the Company cash or
a check sufficient to pay the exercise price;

            (3) when the Common Stock is  registered  under the Exchange Act, by
delivery of shares of Common Stock owned by the Participant valued at their fair
market  value as  determined  by (or in a manner  approved by) the Board in good
faith ("Fair Market Value"),  which Common Stock was owned by the Participant at
least six months prior to such delivery;

            (4) to the extent  permitted by the Board, in its sole discretion by
(i) delivery of a  promissory  note of the  Participant  to the Company on terms
determined by the Board, or (ii) payment of such other lawful  consideration  as
the Board may determine; or

            (5) by any combination of the above permitted forms of payment.

6.    Restricted Stock

      (a) Grants.  The Board may grant Awards  entitling  recipients  to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require  forfeiture  of such shares if issued at no cost) from the  recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied  prior to the end of the  applicable  restriction  period  or  periods
established by the Board for such Award (each, a "Restricted Stock Award").

                                       3
<PAGE>

      (b)  Terms  and  Conditions.  The  Board  shall  determine  the  terms and
conditions of any such  Restricted  Stock Award,  including the  conditions  for
repurchase (or forfeiture)  and the issue price, if any. Any stock  certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board,  deposited by the
Participant, together with a stock power endorsed in blank, with the Company (or
its  designee).  At the expiration of the applicable  restriction  periods,  the
Company (or such designee)  shall deliver the  certificates no longer subject to
such  restrictions  to the  Participant or if the  Participant  has died, to the
beneficiary designated, in a manner determined by the Board, by a Participant to
receive  amounts due or exercise  rights of the  Participant in the event of the
Participant's  death  (the  "Designated  Beneficiary").  In  the  absence  of an
effective  designation by a Participant,  Designated  Beneficiary shall mean the
Participant's estate.

7.    Other Stock-Based Awards

      The Board shall have the right to grant other Awards based upon the Common
Stock having such terms and conditions as the Board may determine, including the
grant  of  shares  based  upon  certain  conditions,  the  grant  of  securities
convertible into Common Stock and the grant of stock appreciation rights.

8.    Adjustments for Changes in Common Stock and Certain Other Events

      (a) Changes in  Capitalization.  In the event of any stock split,  reverse
stock  split,   stock   dividend,   recapitalization,   combination  of  shares,
reclassification  of shares,  spin-off or other similar change in capitalization
or event,  or any  distribution  to holders of Common  Stock other than a normal
cash dividend, (i) the number and class of securities available under this Plan,
(ii) the per-Participant  limit as may be set forth herein, (iii) the number and
class of securities  and exercise  price per share  subject to each  outstanding
Option,  (iv)  the  repurchase  price  per  share  subject  to each  outstanding
Restricted Stock Award, and (v) the terms of each other  outstanding Award shall
be appropriately  adjusted by the Company (or substituted Awards may be made, if
applicable) to the extent the Board shall determine, in good faith, that such an
adjustment  (or  substitution)  is necessary  and  appropriate.  If this Section
applies  and  Section  8(c) also  applies  to any event,  Section  8(c) shall be
applicable to such event, and this Section 8(a) shall not be applicable.

      (b) Liquidation or Dissolution.  In the event of a proposed liquidation or
dissolution  of  the  Company,  the  Board  shall  upon  written  notice  to the
Participants   provide  that  all  then  unexercised  Options  will  (i)  become
exercisable  in full as of a specified  time at least 10 business  days prior to
the  effective  date of such  liquidation  or  dissolution  and  (ii)  terminate
effective upon such  liquidation or dissolution,  except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted  Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

                                       4
<PAGE>

      (c)  Merger  or  Asset  Sale.  Unless  otherwise  provided  in  an  option
agreement,  in the  event  of a  merger  of the  Company  with or  into  another
corporation, or the sale of substantially all of the assets of the Company, each
outstanding Option shall be assumed or an equivalent option or right substituted
by the  successor  corporation  or a  parent  or  subsidiary  of  the  successor
corporation.  In the event that the successor  corporation  refuses to assume or
substitute  for the  Option,  the  Participant  shall fully vest in and have the
right to exercise  the Option in full,  including  shares of Common  Stock as to
which it would not  otherwise  be vested or  exercisable.  If an Option  becomes
fully vested and  exercisable in lieu of assumption or substitution in the event
of a merger or sale of assets, the Board shall notify the Participant in writing
or  electronically  that the Option shall be fully vested and  exercisable for a
period of thirty (30) days from the date of such  notice,  and the Option  shall
terminate  upon  the  expiration  of  such  period.  For  the  purposes  of this
paragraph,  the Option shall be considered  assumed if,  following the merger or
sale of assets,  the option or right  confers  the right to purchase or receive,
for each share of Common Stock  subject to the Option  immediately  prior to the
merger or sale of assets,  the  consideration  (whether  stock,  cash,  or other
securities  or property)  received in the merger or sale of assets by holders of
Common Stock for each share held on the effective date of the  transaction  (and
if holders were  offered a choice of  consideration,  the type of  consideration
chosen by the holders of a majority of the outstanding  shares of Common Stock);
provided,  however, that if such consideration received in the merger or sale of
assets is not solely  common stock of the successor  corporation  or its parent,
the Board may,  with the consent of the successor  corporation,  provide for the
consideration  to be received  upon the exercise of the Option for each share of
Common Stock  subject to the Option to be solely  common stock of the  successor
corporation  or  its  parent  equal  in  fair  market  value  to the  per  share
consideration  received  by  holders  of Common  Stock in the  merger or sale of
assets.  The  Board may  specify  the  effect  of a merger or asset  sale on any
Restricted  Stock Award or other Award granted under the Plan at the time of the
grant of such Award.

      (d)  Change  in  Control.  In the event of a "Change  in  Control"  of the
Company, as defined in paragraph (e) below,  unless otherwise  determined by the
Board prior to the occurrence of such Change in Control, the Options outstanding
as of the date such Change in Control is  determined  to have  occurred that are
not yet exercisable  and vested on such date shall become fully  exercisable and
vested.  The  Board  may  specify  the  effect  of a Change  in  Control  on any
Restricted  Stock Award or other Award granted under the Plan at the time of the
grant of such Award.

      (e)  Definition of "Change in Control".  For purposes of this Section 8, a
"Change in Control"  means when any  "person",  as such term is used in Sections
13(d) and 14(d) of the Exchange Act (other than the Company,  a Subsidiary  or a
Company  employee  benefit  plan,  including  any trustee of such plan acting as
trustee)  is or becomes the  "beneficial  owner" (as defined in Rule 13d-3 under
the  Exchange  Act),  directly  or  indirectly,  of  securities  of the  Company
representing  fifty  percent  (50%) or more of the combined  voting power of the
Company's then outstanding securities.

9.    General Provisions Applicable to Awards

      (a) Transferability of Awards. Except as the Board may otherwise determine
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or  otherwise  encumbered  by the  person  to  whom  they  are  granted,  either
voluntarily  or by operation  of law,  except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant.  References to a Participant,  to the extent relevant in the
context, shall include references to authorized transferees.

      (b)  Documentation.  Each Award shall be evidenced by a written instrument
in such form as the Board  shall  determine.  Each Award may  contain  terms and
conditions in addition to those set forth in the Plan.

      (c) Board Discretion. Except as otherwise provided by the Plan, each Award
may be made alone or in addition or in relation to any other Award. The terms of
each Award  need not be  identical,  and the Board  need not treat  Participants
uniformly.

      (d)  Termination  of Status.  The Board shall  determine  the effect on an
Award of the disability, death, retirement, authorized leave of absence or other
change in the  employment  or other  status of a  Participant  and the extent to
which,  and the period during which, the Participant,  the  Participant's  legal
representative,  conservator,  guardian or Designated  Beneficiary  may exercise
rights under the Award.

      (e)  Withholding.  Each  Participant  shall  pay to the  Company,  or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event  creating  the tax  liability.  Except  as the Board may  otherwise
provide in an Award, when the Common Stock is registered under the Exchange Act,
Participants may satisfy such tax obligations in whole or in part by delivery of
shares of Common Stock,  including  shares  retained from the Award creating the
tax  obligation,  valued at their Fair Market  Value.  The  Company  may, to the
extent permitted by law, deduct any such tax obligations from any payment of any
kind otherwise due to a Participant.

      (f)  Amendment  of Award.  The Board may amend,  modify or  terminate  any
outstanding Award,  including but not limited to, substituting  therefor another
Award  of the  same or a  different  type,  changing  the  date of  exercise  or
realization,  and converting an Incentive  Stock Option to a Nonstatutory  Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board  determines  that the action,  taking into  account any related
action, would not materially and adversely affect the Participant.

                                       6
<PAGE>

      (g) Conditions on Delivery of Stock.  The Company will not be obligated to
deliver  any  shares  of  Common  Stock  pursuant  to  the  Plan  or  to  remove
restrictions  from  shares  previously  delivered  under the Plan  until (i) all
conditions  of the Award  have been met or removed  to the  satisfaction  of the
Company,  (ii) in the opinion of the Company's counsel,  all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable  securities  laws and any applicable  stock exchange or
stock market rules and  regulations,  and (iii) the Participant has executed and
delivered to the Company such  representations  or agreements as the Company may
consider  appropriate to satisfy the  requirements of any applicable laws, rules
or regulations.

      (h) Acceleration. The Board may at any time provide that any Options shall
become  immediately  exercisable in full or in part,  that any Restricted  Stock
Awards shall be free of restrictions in full or in part or that any other Awards
may become exercisable in full or in part or free of some or all restrictions or
conditions, or otherwise realizable in full or in part, as the case may be.

10.   Miscellaneous

      (a) No Right To Employment or Other Status. No person shall have any claim
or right to be  granted  an  Award,  and the  grant  of an  Award  shall  not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company.  The Company expressly  reserves the right at any
time to dismiss or otherwise  terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly  provided in the
applicable Award.

      (b) No Rights As Stockholder.  Subject to the provisions of the applicable
Award,  no  Participant  or  Designated  Beneficiary  shall have any rights as a
stockholder  with respect to any shares of Common Stock to be  distributed  with
respect  to  an  Award  until   becoming  the  record  holder  of  such  shares.
Notwithstanding  the foregoing,  in the event the Company effects a split of the
Common  Stock by means of a stock  dividend  and the  exercise  price of and the
number of shares  subject  to such  Option  are  adjusted  as of the date of the
distribution  of the  dividend  (rather  than as of the  record  date  for  such
dividend),  then an optionee who exercises an Option between the record date and
the distribution  date for such stock dividend shall be entitled to receive,  on
the  distribution  date, the stock dividend with respect to the shares of Common
Stock  acquired upon such Option  exercise,  notwithstanding  the fact that such
shares were not  outstanding  as of the close of business on the record date for
such stock dividend.

      (c) Effective  Date and Term of Plan.  The Plan shall become  effective on
the date on which it is adopted by the Board.  No Awards shall be granted  under
the Plan after the  completion  of ten years from the earlier of (i) the date on
which the Plan was  adopted by the Board or (ii) the date the Plan was  approved
by the Company's  stockholders,  but Awards previously granted may extend beyond
that date.

      (d) Amendment of Plan. The Board may amend,  suspend or terminate the Plan
or any portion thereof at any time.

                                       7
<PAGE>

      (e)  Governing  Law.  The  provisions  of the  Plan  and all  Awards  made
hereunder  shall be governed by and  interpreted in accordance  with the laws of
the State of Florida without regard to any applicable conflicts of law.

      (f) Severability;  Entire Agreement. If any of the provisions of this Plan
or any Award is finally held to be invalid, illegal or unenforceable (whether in
whole or in part),  such provision shall be deemed  modified to the extent,  but
only to the extent, of such invalidity,  illegality or unenforceability  and the
remaining  provisions shall not be affected  thereby;  provided,  that if any of
such provisions is finally held to be invalid, illegal, or unenforceable because
it  exceeds  the  maximum  scope  determined  to be  acceptable  to permit  such
provision to be  enforceable,  such provision  shall be deemed to be modified to
the  minimum  extent  necessary  to  modify  such  scope in  order to make  such
provision  enforceable  hereunder.  The Plan and any Award  contain  the  entire
agreement  of the  parties  with  respect  to the  subject  matter  thereof  and
supersede   all   prior   agreements,    promises,   covenants,    arrangements,
communications,  representations and warranties between them, whether written or
oral with respect to the subject matter thereof.

      (g) Successors  and Assigns.  The terms of this Plan shall be binding upon
and inure to the benefit of Bidville, Inc. and its successors and assigns.

No. R-1

      1. Principal and Interest. World Waste Technologies, Inc. (the "Company"),
for value received,  hereby promises to pay to the order of Trellus  Management,
LLC (the "Holder") in lawful money of the United States, the principal amount of
$750,000,  together with interest accrued on the unpaid principal of this Senior
Promissory  Note (this "Note") at the rate of twelve  percent  (12.0%) per annum
commencing on the date hereof and  compounding  quarterly.  Accrued  interest on
this Note shall be payable in cash at the time the  Company  pays the  principal
amount  of this  Note or any  portion  thereof.  This Note is issued as a senior
unsecured  obligation  of the Company and ranks  senior or parri passu to all of
the Company's other obligations, whether now existing or hereinafter incurred or
created.

      This Note is due and  payable  in United  States  dollars  in  immediately
available  funds  (a) on the  earlier  to occur of (X) July 11,  2005 or (Y) the
closing of an equity  investment  in the Company by the Holder or one or more of
its  affiliates  resulting  in gross  proceeds  to the  Company of at least $8.0
million (the earlier of the foregoing being referred to as the "Maturity Date");
provided,  however,  that the Maturity  Date may be extended by written  notice,
made by the  Holder,  or (b)  immediately  upon  the  occurrence  of an Event of
Default (as defined  below)  specified  in clause (iv) or (v) of Section 6(b) of
this Note and on demand by written  notice  following  a the  occurrence  of any
other Event of Default (as defined  below).  The Company shall,  on the Maturity
Date or, if  earlier,  upon the  occurrence  of an Event of Default  (as defined
below)  specified  in  clause  (iv) or (v) of  Section  6(b) of this Note or the
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 of the  Maturity  Date  or  the  Payment  Date,  as
applicable.  The Company  promises to pay interest on overdue  principal (to the
extent that payment of such interest is enforceable under applicable law) at the
rate of fourteen  percent  (14.0%) per annum.  The Company may prepay all or any
portion of this Note at any time without penalty or premium.

      2.  Limitation  on  Incurrence  of  Additional  Indebtedness.  Without the
approval of the Holder,  until this Note is paid in full,  (a) the Company  will
not incur,  and will not permit any of its subsidiaries to incur, any additional
indebtedness,  other than trade  payables  incurred  in the  ordinary  course of
business,  and (b) the  Company (i) will not permit any of its  subsidiaries  to
issue any capital  stock other than common stock and (ii) will not permit any of
its  subsidiaries  to issue any  capital  stock  having a right,  preference  or
privilege with respect to  liquidation,  the declaration or payment of dividends
or other distributions, or redemption, repurchase or repayment.

      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
applicable  law.  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
