                                   ARTICLE II

                               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 ($.00004
par value per share) 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 of $10,000 or greater
amount, or any lesser amount representing the full remaining outstanding and
unpaid principal portion and 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 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 the Holder's written request for conversion,
Borrower shall issue and deliver to the Holder within five 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. Unless the interest accrued on
the Note is the subject of a Conversion Notice, 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 entered into between the Borrower and Holder relating to this Note
("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/or interest 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 the lower of (i) seventy (70%) of the
average of the closing bid price for the Common Stock on the NASD OTC Bulletin
Board, or on any securities exchange or other securities market on which the
Common Stock is then being traded (or if not so listed, then the lowest reported
bid price as quoted on the "pink sheets" published by the National Quotation
Bureau), for the five (5) trading days immediately preceding the Conversion
Date, or (ii) $0.375 ("Maximum Base Price").


                                       2
<PAGE>


         (c) The Maximum Base Price described in Section 2.1(b)(ii) above and
number and kind of shares or other securities to be issued upon conversion
determined pursuant to Section 2.1(a) and 2.1(b), shall be subject to adjustment
from time to time upon the happening of certain events while this conversion
right remains outstanding, as follows:

          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 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.

          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 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.

          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. Share Issuance. Subject to the provisions of this Section, if the
     Borrower at any time shall issue any shares of Common Stock prior to the
     conversion of the entire principal amount of the Note (otherwise than as:
     (i) provided in Sections 2.1(c)A, 2.1(c)B or 2.1(c)C or this subparagraph
     D; (ii) pursuant to options, warrants, or other obligations to issue
     shares, outstanding on the date hereof as described in the Reports and


                                       3
<PAGE>

     Other Written Information, as such terms are defined in the Subscription
     Agreement (which agreement is incorporated herein by this reference); [(i)
     and (ii) above, are hereinafter referred to as the "Existing Option
     Obligations"] for a consideration less than the Conversion Price that would
     be in effect at the time of such issue, then, and thereafter successively
     upon each such issue, the Conversion Price shall be reduced as follows: (i)
     the number of shares of Common Stock outstanding immediately prior to such
     issue shall be multiplied by the Conversion Price in effect at the time of
     such issue and the product shall be added to the aggregate consideration,
     if any, received by the Borrower upon such issue of additional shares of
     Common Stock; and (ii) the sum so obtained shall be divided by the number
     of shares of Common Stock outstanding immediately after such issue. The
     resulting quotient shall be the adjusted conversion price. Except for the
     Existing option Obligations and options that may be issued under any
     employee incentive stock option and/or any qualified stock option plan
     adopted by the Borrower, for purposes of this adjustment, the issuance of
     any security of the Borrower carrying the right to convert such security
     into shares of Common Stock or of any warrant, right or option to purchase
     Common Stock shall result in an adjustment to the Conversion Price upon the
     issuance of shares of Common Stock upon exercise of such conversion or
     purchase rights.

         (d) During the period the conversion right 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, a new Note containing the same
date and provisions of this Note shall 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.
