                              By:     Carl  Dilley
                              Its:     President<PAGE>
                                                                    EXHIBIT 10.3
                           HOSTING SITE NETWORK, INC.
                           --------------------------

                      2002 NON-STATUTORY STOCK OPTION PLAN

     1.     PURPOSE  OF  THE  PLAN.  The  Hosting  Site  Network,  Inc.,  2002
            ----------------------
Non-Statutory  Stock  Option  Plan  (the  "Plan")  is  intended  to  advance the
interests of Hosting Site Network, Inc. (the "Company") by inducing individuals,
and  eligible  entities  (as  hereinafter  provided)  of outstanding ability and
potential  to  join, remain with, or provide consulting or advisory services to,
the  Company,  by  encouraging  and  enabling  eligible  employees, non-employee
Directors,  consultants  and  advisors  to  acquire proprietary interests in the
Company,  and  by providing the participating employees, non-employee Directors,
consultants  and advisors with an additional incentive to promote the success of
the Company. This is accomplished by providing for the granting of Non-Statutory
Stock  Options (the "Options") to employees, non-employee Directors, consultants
and  advisors.

     2.   ADMINISTRATION. The Plan shall be administered by the Board of
          --------------
Directors  of  the  Company  (the  "Board  of Directors") or by a committee (the
"Committee")  chosen  by  the  Board of Directors. Except as herein specifically
provided,  the  interpretation and construction by the Board of Directors or the
Committee  of  any provision of the Plan or of any Option granted under it shall
be  final and conclusive. The receipt of Options by Directors, or any members of
the  Committee,  shall not preclude their vote on any matters in connection with
the  administration  or  interpretation  of  the  Plan.

     3. SHARES SUBJECT TO THE PLAN. The stock subject to Options granted under
        ---------------------------
the  Plan  shall  be  shares  of the Company's Common Stock, par value $.001 per
share  (the  "Common  Stock"),  whether  authorized  but unissued or held in the
Company's  treasury.  The  maximum number of shares of Common Stock which may be
issued  pursuant  to  Options  granted  under  the  Plan shall not exceed in the
aggregate  one  million  (1,000,000) shares, subject to adjustment in accordance
with  the provisions of Section 11 hereof.  The Company shall at all times while
the  Plan  is  in force reserve such number of shares of Common Stock as will be
sufficient  to satisfy the requirements of all outstanding Options granted under
the  Plan.  In  the  event  any  Option  granted  under the Plan shall expire or
terminate  for  any  reason without having been exercised in full or shall cease
for  any  reason  to be exercisable in whole or in part, the un-purchased shares
subject  thereto  shall  again  be  available  for  Options  under  the  Plan.

     4. PARTICIPATION. The class of individual or entity that shall be eligible
        -------------
to  receive  Options  under the Plan shall be all employees (including officers)
and  non-employee  Directors  of,  or  consultants  and  advisors to, either the
Company  or  any  subsidiary corporation of the Company; provided, however, that
Options  shall  not  be  granted to any such consultants and advisors unless (i)
bona fide services have been or are to be rendered by such consultant or advisor
---- ----
and  (ii)  such  services  are  not  in  connection  with  the  offer or sale of
securities  in  a  capital  raising  transaction.  The Board of Directors or the
Committee,  in  its  sole discretion, but subject to the provisions of the Plan,
shall determine the employees and non-employee Directors of, and the consultants

                                       35
<PAGE>

and  advisors  to,  the  Company and its subsidiary corporations to whom Options
shall  be granted, and the number of shares to be covered by each Option, taking
into  account  the  nature  of  the  employment  or  services  rendered  by  the
individuals  or  entities  being  considered,  their  annual compensation, their
present  and  potential  contributions  to  the success of the Company, and such
other  factors  as  the  Board  of Directors or the Committee may deem relevant.

     5. STOCK OPTION AGREEMENT. Each Option granted under the Plan shall be
        ----------------------
authorized by the Board of Directors or the Committee, and shall be evidenced by
a  Stock  Option  Agreement  which  shall  be executed by the Company and by the
individual or entity to whom such Option is granted.  The Stock Option Agreement
shall  specify  the  number  of shares of Common Stock as to which any Option is
granted, the period during which the Option is exercisable, the option price per
share  thereof,  and  such other terms and provisions not inconsistent with this
Plan.

     6. GRANT OF NON-STATUTORY STOCK OPTIONS. The Options granted under the Plan
        ------------------------------------
are not intended to meet the requirements of Section 422 of the Internal Revenue
Code  of  1986,  as  amended  (the  "Code"). The Options shall be subject to the
following  terms  and  conditions:

     (1)  An  Option  may  be  granted  to  any individual or entity eligible to
receive  an  Option  under  the  Plan  pursuant  to  Section  4  hereof.

     (2)  The  option  price  of the shares of Common Stock subject to an Option
shall  be  determined  by  the  Board of Directors or the Committee, in its sole
discretion,  at  the  time  of  the  grant  of  the  Option.

     (3)  An  Option  granted under the Plan may be of such duration as shall be
determined  by  the  Board  of  Directors  or  the Committee (subject to earlier
termination  as  expressly  provided  in  Section  9  hereof).

     7. RIGHTS OF OPTION HOLDERS. The holder of any Option granted under the
        -------------------------
Plan  shall  have  none of the rights of a stockholder with respect to the stock
covered  by  his  Option  until  such stock shall be transferred to him upon the
exercise  of  his  Option.

     8. TRANSFERABILITY. No Option granted under the Plan shall be transferable
        ---------------
by the individual or entity to whom it was granted otherwise than by will or the
laws  of  descent and distribution, and, during the lifetime of such individual,
shall  not  be  exercisable  by  any  other  person,  but  only  by  him.

     9. TERMINATION OF EMPLOYMENT OR DEATH.
        -----------------------------------

     (1)     Subject  to  the  terms  of  the  Stock  Option  Agreement,  if the
employment of an employee by, or the services of a non-employee Director for, or
consultant or advisor to, the Company or a subsidiary corporation of the Company
shall  be  terminated  for  cause  or  voluntarily by the employee, non-employee
Director,  consultant or advisor, then his or its Option shall expire forthwith.
Subject  to  the  terms of the Stock Option Agreement, and except as provided in
subsections  (b) and (c) of this Section 9, if such employment or services shall

                                       36
<PAGE>

terminate  for  any  other reason, then such Option may be exercised at any time
within  three  (3)  months  after such termination, subject to the provisions of
subsection (d) of this Section 9. For purposes of the Plan, the retirement of an
individual  either  pursuant  to  a  pension  or  retirement plan adopted by the
Company  or  at  the  normal retirement date prescribed from time to time by the
Company  shall be deemed to be termination of such individual's employment other
than  voluntarily  or  for  cause.  For  purposes  of  this  subsection  (a), an
employee,  non-employee Director, consultant or advisor who leaves the employ or
services  of the Company to become an employee or non-employee Director of, or a
consultant  or  advisor  to,  a  subsidiary  corporation  of  the  Company  or a
corporation  (or  subsidiary or parent corporation of the corporation) which has
assumed  the  Option of the Company as a result of a corporate reorganization or
the  like shall not be considered to have terminated his employment or services.

     (2) Subject to the terms of the Stock Option Agreement, if the holder of an
Option  under  the  Plan  dies  (i)  while  employed  by,  or while serving as a
non-employee  Director  for  or  a  consultant  or  advisor to, the Company or a
subsidiary corporation of the Company, or (ii) within three (3) months after the
termination of his employment or services other than voluntarily by the employee
or  non-employee Director, consultant or advisor, or for cause, then such Option
may, subject to the provisions of subsection (d) of this Section 9, be exercised
by  the  estate of the employee or non-employee Director, consultant or advisor,
or  by  a  person  who  acquired the right to exercise such Option by bequest or
inheritance or by reason of the death of such employee or non-employee Director,
consultant  or  advisor  at  any  time  within  one  (1)  year after such death.

     (3) Subject to the terms of the Stock Option Agreement, if the holder of an
Option  under  the  Plan  ceases employment or services because of permanent and
total  disability  (within  the  meaning  of Section 22(e)(3) of the Code) while
employed  by,  or  while serving as a non-employee Director for or consultant or
advisor  to,  the  Company or a subsidiary corporation of the Company, then such
Option  may,  subject  to the provisions of subsection (d) of this Section 9, be
exercised  at  any time within one (1) year after his termination of employment,
termination  of  Directorship or termination of consulting or advisory services,
as  the  case  may  be,  due  to  the  disability.

     (4) An Option may not be exercised pursuant to this Section 9 except to the
extent  that  the  holder  was  entitled  to  exercise the Option at the time of
termination  of  employment,  termination  of  Directorship,  termination  of
consulting or advisory services, or death, and in any event may not be exercised
after  the  expiration  of  the  Option.

     (5)  For  purposes  of  this  Section  9, the employment relationship of an
employee  of  the  Company or of a subsidiary corporation of the Company will be
treated as continuing intact while he is on military or sick leave or other bona
fide  leave  of absence (such as temporary employment by the Government) if such
leave  does  not exceed ninety (90) days, or, if longer, so long as his right to
reemployment  is  guaranteed  either  by  statute  or  by  contract.

     10.  EXERCISE  OF  OPTIONS.
          ---------------------

     (1)     Unless otherwise provided in the Stock Option Agreement, any Option
granted  under  the  Plan  shall be exercisable in whole at any time, or in part

                                       37
<PAGE>

from time to time, prior to expiration. The Board of Directors or the Committee,
in  its  absolute discretion, may provide in any Stock Option Agreement that the
exercise  of  any  Options  granted  under the Plan shall be subject (i) to such
condition  or  conditions  as  it  may  impose, including, but not limited to, a
condition  that  the  holder  thereof  remain  in  the  employ or service of, or
continue  to  provide  consulting  or  advisory  services  to,  the Company or a
subsidiary  corporation  of the Company for such period or periods from the date
of  grant  of  the  Option  as  the  Board of Directors or the Committee, in its
absolute  discretion,  shall  determine;  and (ii) to such limitations as it may
impose.

     (2)  An Option granted under the Plan shall be exercised by the delivery by
the  holder  thereof  to  the  Company at its principal office (attention of the
Secretary)  of  written notice of the number of shares with respect to which the
Option  is  being exercised. The notice shall be given pursuant to the Notice of
Exercise  form  attached  to  the  Stock  Option Agreement. Such notice shall be
accompanied  by  payment of the full option price of such shares, and payment of
such  option  price  shall  be  made  by  the holder's delivery of (i) his check
payable  to the order of the Company, (ii) previously acquired Common Stock, the
fair  market  value  of which shall be determined as of the date of exercise, if
this  method  of  payment  is otherwise permitted by the Stock Option Agreement,
(iii)  by  "cash-less" exercise, if cash-less exercise is otherwise permitted by
the  Stock Option Agreement, or (iv) by the holder's delivery of any combination
of the foregoing (i), (ii) and (iii) to the extend permitted by the Stock Option
Agreement.

     11.     ADJUSTMENT  UPON  CHANGE  IN  CAPITALIZATION.
             --------------------------------------------

     (1)     In the event that the outstanding Common Stock is hereafter changed
by  reason  of  reorganization,  merger,  consolidation,  recapitalization,
reclassification,  stock  split-up,  combination of shares, reverse split, stock
dividend  or  the  like, an appropriate adjustment shall be made by the Board of
Directors or the Committee in the aggregate number of shares available under the
Plan,  and  in  the  number  of  shares  and  option  price per share subject to
outstanding  Options.  If  the  Company  shall  be reorganized, consolidated, or
merged  with  another  corporation, the holder of an Option shall be entitled to
receive  upon  the  exercise of his Option the same number and kind of shares of
stock  or the same amount of property, cash  or securities as he would have been
entitled  to receive upon the happening of any such corporate event as if he had
been,  immediately  prior  to  such  event,  the  holder of the number of shares
covered  by  his  Option.

     (2)  Any  adjustment in the number of shares shall apply proportionately to
only  the unexercised portion of the Option granted hereunder. If fractions of a
share  would result from any such adjustment, the adjustment shall be revised to
the  next  lower  whole  number  of  shares.

     12.     FURTHER  CONDITIONS  OF  EXERCISE.
             ---------------------------------

     (1)     Unless prior to the exercise of the Option the shares issuable upon
such  exercise  have been registered with the Securities and Exchange Commission
pursuant  to  the  Act,  the  notice  of  exercise  shall  be  accompanied  by a
representation or agreement of the person or estate exercising the Option to the
Company  to  the  effect  that  such  shares  are  being acquired for investment
purposes  and  not  with  a  view  to  the  distribution thereof, and such other

                                       38
<PAGE>

documentation  as  may  be  required  by  the  Company, unless in the opinion of
counsel  to  the  Company such representation, agreement or documentation is not
necessary  to  comply  with  such  Act.

     (2)  The  Company  shall not be obligated to deliver any Common Stock until
there  has  been  qualification  under  or compliance with such federal or state
laws,  rules  or  regulations  as  the  Company  may  deem  applicable.

     13.  EFFECTIVENESS  OF  THE  PLAN.  The  Plan shall become operative and in
          ----------------------------
effect  on  such date as shall be fixed by the Board of Directors of the Company
in  its  sole  discretion.

     14.     TERMINATION,  MODIFICATION  AND  AMENDMENT.
             ------------------------------------------

     (1)     The Plan (but not the Options) shall terminate on a date within ten
(10)  years  from  the  date  of  its  adoption by the Board of Directors of the
Company, or sooner as hereinafter provided, and no Option shall be granted after
termination  of  the  Plan.

     (2)  The  Board  of Directors may at any time, on or before the termination
date  referred  to  in Section 14(a) hereof, terminate the Plan, or from time to
time make such modifications or amendments to the Plan as it may deem advisable;
provided,  however,  that  the  Board of Directors shall not increase (except as
otherwise provided by Section 11 hereof) the maximum number of Options which may
be  granted  hereunder.

     (3) No termination, modification, or amendment of the Plan may, without the
consent  of the individual or entity to whom any Option shall have been granted,
adversely  affect  the  rights  conferred  by  such  Option.

     15.  NOT  A CONTRACT OF EMPLOYMENT. Nothing contained in the Plan or in any
          ------------------------------
Stock  Option  Agreement executed pursuant hereto shall be deemed to confer upon
any  individual  or  entity to whom an Option is or may be granted hereunder any
right  to  remain  in  the  employ  or  service  of  the Company or a subsidiary
