Address, provided that any payment otherwise due on a Saturday, Sunday or legal

under the laws of the State of Illinois or the laws of any other state governing
the repayment hereof, then so much of such interest or other consideration as
shall be deemed to be usurious shall be held by the holder as security for the
repayment of the principal amount hereof and shall otherwise be waived. This
Note is one of a series of Notes aggregating up to $4,000,000 in principal. Any
conversion of this Note is subject to filing the Certificate of Amendment as set
forth in Section 3 of the Subscription Agreement of even date herewith.

            1. TRANSFERS OF NOTE TO COMPLY WITH THE 1933 ACT

            The Holder agrees that this Note may not be sold, transferred,
pledged, hypothecated or otherwise disposed of except as follows: (1) to a
person whom the Note may legally be transferred without registration and without
delivery of a current prospectus under the 1933 Act with respect thereto and
then only against receipt of an agreement of such person to comply with the
provisions of this Section 1 with respect to any resale or other disposition of
the Note; or (2) to any person upon delivery of a prospectus then meeting the
requirements of the 1933 Act relating to such securities and the offering
thereof for such sale or disposition, and
 thereafter to all successive assignees.

            2. PREPAYMENT; AUTOMATIC CONVERSION; CONVERSION

whole or in part without premium or penalty, at any time. Upon any prepayment of
the entire principal amount of this Note, all accrued, but unpaid interest shall
be paid to the Holder on the date of prepayment.

            At any time prior to or at the time of repayment of this Note by the
Company, the Holder may elect to convert some or all of the principal and
interest owing on this Note into shares of the Company's common stock, subject
to the restrictions contained herein. The conversion rate shall equal the amount
to be converted, divided by $.10 per share. Such election to convert shall be
evidenced by completion of the conversion notice attached hereto and delivery of
such notice to the Company. The Holder's right to convert the obligations due
under this Note to common stock shall supercede the Company's right to repay
such obligations in cash, subject to the restrictions contained herein.

            At anytime prior to the Maturity Date, this Note is automatically
converted into shares of common stock of the Company in the event that (i) if
the closing sales price of the Company's common stock is equal to or in excess
of $.30 for a period of twenty (20) consecutive trading days; (ii) the daily
average trading volume for those twenty (20) days is equal to or in excess of
250,000; (iii) the Common Stock underlying the Notes and Warrants is registered
for resale under the 1933 Act; (iv) the Company has sufficient shares of Common
Stock authorized to issue for the converted notes; and (v) Suzanne Gombrich's
secured convertible promissory note has been converted to equity or paid in
full.

            In the event the Company intends to prepay any or all of the
outstanding principal or interest on this Note, the Company must provide written
notice to the Holder at least ten (10) days prior to the proposed prepayment
date ("Prepayment Date"). If the Holder wishes to convert any or all of the
outstanding principal or interest on this Note rather than receiving payment in
cash, the Holder must notify the Company no later than five (5) days prior to
the Prepayment Date by delivering to the Company a completed copy of the
conversion notice attached hereto. If the Holder wishes to convert any or all of
the outstanding principal or interest on this Note prior to the Maturity Date,
rather than receiving payment in cash, the Holder must notify the Company no
later than five (5) days prior to the Maturity Date by delivering to the Company
a completed copy of the conversion notice attached hereto.

            In the event the Holder elects to convert a portion of the principal
or interest on this Note, or the Company prepays any portion of the principal or
interest on this Note, the Holder shall deliver this Note to the Company and the
Company shall issue a new Note to the Holder evidencing the reduction of
principal or interest.

            3. SECURITY. This Note is subject to a General Security Agreement of
even date between the Company and the Holder.
