                                   ARTICLE 2
                                CONVERSION RIGHTS

     The  Holder  shall  have the right to  convert  the  principal  amount  and
interest due under this Note into Shares of the  Borrower's  Common Stock as set
forth below.

2.1. Conversion into the Borrower's Common Stock.

     (a)  The Holder  shall have the right from and after the  issuance  of this
          Note and then at any time  until this Note is fully  paid,  to convert
          any outstanding and unpaid principal  portion of this Note,  and/or at
          the Holder's  election,  the interest accrued on the Note (the date of
          giving of such notice of conversion  being a  "Conversion  Date") into
          fully paid and  nonassessable  shares of common  stock of  Borrower as
          such stock exists on the date of issuance of this Note,  or any shares
          of capital stock of Borrower into which such stock

                                       1



          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,  attached hereto as Exhibit A, as described
          in the  subscription  agreement  entered into between the Borrower and
          Holder relating to this Note (the "Subscription  Agreement"),  all the
          terms of which  are  incorporated  herein  by this  reference,  of the
          Holder's  written  request for  conversion,  Borrower  shall issue and
          deliver  to  the  Holder  within  five  (5)  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.  At the
          election of the Holder,  the Borrower will deliver  accrued but unpaid
          interest  on the Note  through  the  Conversion  Date  directly to the
          Holder on or before the Delivery Date (as defined in the  Subscription
          Agreement).  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 (and interest, at the election of the Holder)
          of the Note to be converted, by the Conversion Price.

     (b)  Subject to  adjustment  as  provided  in Section  2.1(c)  hereof,  the
          Conversion Price per share shall be Four Cents ($.04).

     (c)  The Conversion Price and number and kind of shares or other securities
          to be issued upon conversion  shall be subject to adjustment from time
          to time upon the  happening of certain  events  while this  conversion
          right remains outstanding, as follows:

          (i)  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 corporation, 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.

          (ii) 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  such number 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.

          (iii)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 Base 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

                                       2


               total  number of shares of Common Stock  outstanding  immediately
               prior to such event.

     (d)  Beginning  as of such time as Borrower  has  authorized  but  unissued
          shares of Common Stock available  therefor (but in no event later than
          the  earlier  of  (i)  three  months  after  Borrower's   current  S-1
          registration statement under review by the Commission with file number
          333-60574 (the "Current Registration  Statement") becomes effective or
          is abandoned or (ii) April 10,  2004),  and for the  remaining  period
          during which the  conversion  right under this Note  exists,  Borrower
          will  reserve  from  its  authorized  and  unissued   Common  Stock  a
          sufficient  number of shares to  provide  for the  issuance  of Common
          Stock upon the full conversion of this Note.  Borrower represents that
          upon issuance, such shares will be duly and validly issued, fully paid
          and  non-assessable.  Borrower  agrees that its  issuance of this Note
          shall  constitute full authority to its officers,  agents and transfer
          agents who are charged  with the duty of executing  and issuing  stock
          certificates  to  execute  and issue the  necessary  certificates  for
          shares of Common Stock upon the conversion of this Note.

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  and  the  Subscription
     Agreement.  Upon  partial  conversion  of this Note,  if  requested  by the
     Holder,  a new Note  containing  the same date and  provisions of this Note
     shall be issued by the Borrower to the Holder for the  remaining  principal
     balance of this Note and  interest  which shall not have been  converted or
     paid.

2.3. Maximum  Conversion.  The  Holder  shall not be  entitled  to  convert on a
     Conversion  Date that amount of the Note in connection  with that number of
     shares  of  Common  Stock  which  would be in  excess of the sum of (i) the
     number of shares of Common Stock  beneficially  owned by the Holder and its
     affiliates  on a Conversion  Date,  and (ii) the number of shares of Common
     Stock  issuable  upon the  conversion of the Note with respect to which the
     determination  of this provision is being made on a Conversion  Date, which
     would result in  beneficial  ownership by the Holder and its  affiliates of
     more than 9.99% of the  outstanding  shares of Common Stock of the Borrower
     on  such  Conversion  Date.  For  the  purposes  of  the  provision  to the
     immediately preceding sentence, beneficial ownership shall be determined in
     accordance  with Section 13(d) of the  Securities  Exchange Act of 1934, as
     amended,  and Regulation 13d-3  thereunder.  Subject to the foregoing,  the
     Holder  shall not be limited  to  aggregate  conversions  of only 9.99% and
     aggregate  conversion by the Holder may exceed 9.99%. The Holder shall have
     the authority and obligation to determine whether the restriction contained
     in this Section 2.3 will limit any  conversion  hereunder and to the extent
     that the Holder  determines  that the limitation  contained in this Section
     applies,  the  determination  of which portion of the Notes are convertible
     shall be the  responsibility  and obligation of the Holder.  The Holder may
     void the conversion  limitation  described in this Section 2.3 upon 75 days
     prior written notice to the Borrower.  The Holder may allocate which of the
     equity of the  Borrower  deemed  beneficially  owned by the Holder shall be
     included in the 9.99% amount  described  above and which shall be allocated
     to the excess above 9.99%.

                                   ARTICLE 3
                                EVENT OF DEFAULT
