                                   ARTICLE II

                                CONVERSION RIGHTS

     At any time  during  the term of this  Note,  provided  the  conditions  of
Section 1.2 above are satisfied,  the Holder may deliver a written  notification
(the "NOTICE OF  CONVERSION")  to the Borrower  setting forth the portion of the
principal  amount of the Note and/or  interest due and payable (the  "INVESTMENT
AMOUNT") that the Holder  exercises its conversion  rights with respect thereto,
subject to the terms and provisions set forth below.

     2.1. Conversion into the Borrower's Common Stock

     (a) The Holder shall have the right, but not the obligation, from and after
the Borrower's receipt of an Notice of Conversion or the occurrence of any Event
of Default, as the case may be, provided the conditions of Section 2.1 have been
fulfilled,  and then at any time until this Note is fully  paid,  to convert the
principal portion of this Note and/or interest due and payable set forth in each
such Notice of  Conversion or the entire  principal  portion of this Note and/or
interest due and payable following the occurrence or an Event of Default, as the
case may be,  into fully paid and  nonassessable  shares of common  stock of the
Borrower  as such stock  exists on the date of  issuance  of this  Note,  or any
shares of capital stock of the Borrower into which such stock shall hereafter be
changed or reclassified  (the "COMMON STOCK") at the conversion price as defined
in Section  2.1(b)  hereof  (the  "CONVERSION  PRICE"),  determined  as provided
herein. Upon delivery to the Borrower of a Notice of Conversion substantially in
the form  attached  to this  Note,  giving  the  Holder's  written  request  for
conversion  (the date of giving such notice of  conversion  being a  "CONVERSION
DATE"), the Borrower shall issue and deliver to the Holder within three business
days  from the  Conversion  Date that  number of shares of Common  Stock for the
portion of the Note converted in accordance  with the  foregoing.  The number of
shares of Common Stock to be issued upon each  conversion  of this Note shall be
determined by dividing that portion of the principal of the Note to be converted
and  interest,  if any, by the  Conversion  Price,  and then  multiplied  by One
Hundred Twenty Percent (120%).

     (b)  Subject to  adjustment  as  provided  in Section  2.1(c)  hereof,  the
Conversion  Price per share shall be the the average of the three lowest closing
bid prices for the  Common  Stock on the OTC  Bulletin  Board,  NASDAQ  SmallCap
Market,  NASDAQ  National Market System,  American Stock  Exchange,  or New York
Stock Exchange  (whichever of the foregoing is at the time the principal trading
exchange or market for the Common Stock, the "PRINCIPAL Market"), or if not then
trading on a Principal Market, such other principal market or exchange where the
Common Stock is listed or traded,  for the thirty (30) trading days prior to but
not including the Conversion Date.

     (c) The  Conversion  Price  described  above shall be subject to adjustment
from time to time upon the  happening of certain  events  while this  conversion
right remains outstanding, as follows:

                                       2
<PAGE>
     A.  Merger,  Sale  of  Assets,  etc.  If the  Borrower  at any  time  shall
consolidate  with or merge into or sell or convey all or  substantially  all its
assets to any other  person or  entity,  this Note,  as to the unpaid  principal
portion  thereof and accrued  interest  thereon,  shall  thereafter be deemed to
evidence  the  right  to  purchase  such  number  and  kind of  shares  or other
securities and property as would have been issuable or  distributable on account
of such consolidation,  merger, sale or conveyance,  upon or with respect to the
securities subject to the conversion or purchase right immediately prior to such
consolidation,  merger,  sale  or  conveyance.  The  foregoing  provision  shall
similarly  apply to  successive  transactions  of a  similar  nature by any such
successor or purchaser.  Without  limiting the generality of the foregoing,  the
anti-dilution  provisions of this Section shall apply to such securities of such
successor or purchaser after any such consolidation, merger, sale or conveyance.

     B.   Reclassification,   etc.  If  the  Borrower  at  any  time  shall,  by
reclassification  or  otherwise,  change  the  Common  Stock  into the same or a
different  number of  securities  of any class or classes,  this Note, as to the
unpaid principal portion thereof and accrued interest thereon,  shall thereafter
be  deemed  to  evidence  the  right to  purchase  an  adjusted  number  of such
securities  and kind of  securities as would have been issuable as the result of
such  change  with  respect  to the  Common  Stock  immediately  prior  to  such
reclassification or other change.

     C. Stock Splits,  Combinations and Dividends. If the shares of Common Stock
are  subdivided or combined into a greater or smaller number of shares of Common
Stock,  or if a dividend is paid on the Common Stock in shares of Common  Stock,
the Conversion Price shall be proportionately  reduced in case of subdivision of
shares or stock dividend or proportionately increased in the case of combination
of shares,  in each such case by the ratio  which the total  number of shares of
Common Stock outstanding  immediately after such event bears to the total number
of shares of Common Stock outstanding immediately prior to such event.

     D. Stock Sale.  If, prior to conversion  of the entirety of this Note,  the
Borrower  enters into any  agreement to sell its Common  Stock or a  convertible
instrument  that converts into its Common Stock prior to conversion of this Note
at a price  less than the  Conversion  Price of this Note,  then the  Conversion
Price of any  outstanding  principal and interest of this Note shall be reset to
the price of that offering.

     2.2 Method of Conversion. This Note may be converted by the Holder in whole
or in part as described in Section  2.1(a)  hereof.  Upon partial  conversion of
this  Note,  a new Note  containing  the same date and  provisions  of this Note
shall, at the request of the Holder, be issued by the Borrower to the Holder for
the  principal  balance  of this  Note and  interest  which  shall not have been
converted or paid.
