                                 ---------------

     Mediacomm Broadcasting Systems, Inc., a corporation duly organized and
existing under the laws of the State of Colorado, d/b/a Shopbiz.com (hereinafter
referred to as "Shopbiz.com" or "Maker"), for value received, hereby promises to
pay to the following person (the "Lender"):

     *

the principal sum of * dollars ($*), as loaned by the Lender to the Maker as set
forth in the Funding Agreement of even date herewith and incorporated herein
(the "Funding Agreement"), in such lawful money of the United States of America
as at the time of payment shall be legal tender for the payment of public and
private debts, on the terms and at the time hereinafter provided.

     This Note is subject to the terms and conditions of the Funding Agreement
and any inconsistencies between this Note and the Funding Agreement shall be
governed by the Funding Agreement. This Note is also subject to the following
further terms and provisions:

<PAGE>


     1. Payment of Principal and Interest. The outstanding principal amount of
this Note, which amount shall be equal to the funds loaned by Lender to the
Maker hereunder and not otherwise repaid pursuant hereto, together with all
interest then accrued shall be due and payable on the date of the initial
release of funds under the registration statement (the "Registration Statement")
filed by the Company pursuant to the Funding Agreement or one year from the date
hereof, whichever shall first occur (the "Due Date"). Interest on the
outstanding principal shall accrue at the rate of ten percent (10%) per annum
from the date of delivery of such principal funds by the Lender. All interest
shall be calculated on the basis of a 365-day year, counting the actual number
of days elapsed from the date the principal amount is delivered to the Maker
through the Due Date. Interest on any overdue payments of principal and interest
due hereunder shall accrue and be payable at the rate of twelve percent (12%)
per annum, based on the actual number of days elapsed from the date such
principal or interest payment was due to the date of actual payment.

     2. Prepayment. This Note is subject to prepayment, in whole or in part, at
any time upon not less than 30 days notice by registered mail at the election of
the Maker. Prepayment shall be effected by paying the amount equal to the
outstanding principal amount of this Note, plus all interest accrued to the date
of prepayment. During the 30 days following the date of any notice of
prepayment, the holder shall have the right to convert this Note to the common
stock of the Maker, on the terms and conditions provided for in paragraph 2
above.

     3. Satisfaction and Discharge of Note. This Note shall cease to be of
further effect when:

          a. The Maker has paid or caused to be paid all sums payable hereunder
by the Maker, including all outstanding principal amounts and interest accrued
under the Note; and

          b. All the conditions precedent herein provided for relating to the
satisfaction and discharge of this Note have been complied with.

     4. Events of Default. "Event of Default," when used herein, whatever the
reason for such Event of Default and whether it shall be voluntary or
involuntary or be effected by operation of law pursuant to any judgment, decree,
or order of any court or any order, rule, or regulation of any administration or
government body or be caused by the provisions of any paragraph herein means any
one of the following events:

<PAGE>


          a. Default in the payment of any principal or interest on this Note
when it becomes due and payable, and continuance of such default for a period of
30 days; or

          b. Default in the performance or breach of any covenant or warranty of
the Maker in this Note (other than a covenant or warranty, the breach or default
in performance of which is elsewhere in this section specifically dealt with),
and continuation of such default or breach for a period of 30 days after there
has been given to the Maker by registered or certified mail, by the holder of
this Note, a written notice specifying such default or breach and requiring it
to be remedied and stating that such notice is a notice of default hereunder; or

          c. The entry of a decree or order by a court having jurisdiction in
the premises adjudging the Maker a bankrupt or insolvent under the Federal
Bankruptcy Act or any other applicable federal or state law, or appointing a
receiver, liquidator, assignee, trustee (or other similar official) of the Maker
or of any substantial part of its property , or ordering the winding up or
liquidation of its affairs, and the continuance of any such decree or order
unstayed and in effect for a period of 60 consecutive days;

          d. The institution by the Maker of proceedings to be adjudicated a
bankrupt or insolvent, or the consent by it to the institution of bankruptcy or
insolvency proceedings against it, or a filing by it of a petition or answer or
consent seeking reorganization or relief under the Federal Bankruptcy Act or any
other applicable federal or state law; or the consent by it to the filing of any
such petition or the appointment of a receiver, liquidator, assignee, trustee
(or other similar official) of the Maker or of any substantial part of its
property, or the making by it of any assignment for the benefit of creditors, or
the admission by it in writing of its inability to pay its debts generally as
they become due, or the taking of corporate action by the Maker in furtherance
of any such action; or

          e. Any material breach of the representations or warranties of the
Maker in, the Funding Agreement, or any material default of the Maker of the
terms and conditions of the Funding Agreement.

     5. Conversion to Shares on Default. As an alternative to any remedy
available to the Lender under law or equity in the event of the failure of the
Maker to have paid or to pay the principal and interest due hereunder by or on
*, 2000, then, on and after that date, until such the time said principal and
interest shall have been paid, the Lender shall have the option to convert all

<PAGE>


or any portion of the amount due on this Note on the date of conversion into
shares of the common stock of the Maker at the rate of $0.10 per share of common
stock.

     6. Acceleration of Maturity. If an Event of Default occurs and is
continuing then, in every such case, the holder of this Note may declare the
outstanding principal of this Note to be due and payable immediately, by a
notice in writing to the Maker of such default, and upon any such declaration,
such principal shall become immediately due and payable. At such time after such
declaration of acceleration has been made, and before a judgment or decree for
payment of money due has been obtained by the holder, the holder of this Note,
by written notice to the Maker, may rescind and annul such declaration and its
consequences, if all Events of Default, other than the nonpayment of the
principal of this Note which has become due solely by such acceleration, has
been cured or waived. No such rescission shall affect any subsequent default or
impair any right consequent thereon.

     7. Restrictions. The Lender, by acceptance hereof, represents and warrants
as follows:

          a. The Note is being acquired for the Lender's own account to be held
for investment purposes only and not with a view to, or for, resale in
connection with any distribution of such Note or any interest therein without
registration, or an applicable exemption from registration, or other compliance
under the Act, or any state securities law, and the holder hereof has no direct
or indirect participation in any such undertaking or in underwriting such an
undertaking.

          b. The Lender knows and understands that the Note has not been
registered under the Act, or any state securities laws, and the Maker is under
no obligation to register the Note under the Act or such state securities laws.

     8. Non-Negotiability and Assignment. This Note is non-negotiable and is
assignable by the Lender only with the prior written consent of the Maker.

     9. Presentment Waiver. The Maker, and guarantors hereof, if any, severally
waive presentment for payment, protest, and notice of protest and of nonpayment
of this Note.
