         6.       CONFIDENTIALITY OF INFORMATION. Hamilton agrees that neither
                  it nor its employees or agents will, during the Term of this
                  Contract, or at any time thereafter, disclose or divulge or
                  use, directly or indirectly, for its own benefit or the

                  information, data, trade secrets, inventions, programs, and
                  business policies and procedures (together, "Protected
                  Information") in relation to the business of the Company
                  learned in connection with its work for the Company. The
                  provisions of this paragraph shall survive the termination of
                  the Contract, and shall continue until the Protected
                  Information becomes public knowledge through no fault of
                  Hamilton or any of its employees or agents. Hamilton
                  acknowledges that it is aware, and that it will advise each of
                  its employees and agents who is informed as to the matters
                  which are the subject of this agreement, that the United
                  States securities laws prohibit persons who are in possession
                  of material, non-public information concerning an issuer from
                  purchasing or selling securities of such issuer and from
                  communicating such information to any other person under
                  circumstances in which it is reasonably foreseeable that such
                  person is likely to purchase or sell such securities, and
                  Hamilton agrees to comply with such laws, and to ensure
                  compliance with such laws by any employees or agents it
                  utilizes to provide services hereunder.

         7.       TERMINATION. Hamilton's services may be terminated at any time
                  by the Company upon written notice. If Hamilton's services are
                  terminated by the Company without cause, Hamilton will be
                  entitled to receive and retain the unvested portion of any
                  stock grant pursuant to Paragraph 4 above along with the
                  portion of any monthly fee due up to the date of termination.
                  If services are terminated by the Company for justifiable
                  cause, as hereafter defined, Hamilton will not be entitled to
                  any compensation after the date of

<PAGE>

                  termination, and the unvested portion of any stock grant shall
                  be forfeited.

                  A.       If Hamilton terminates this agreement for any reason,
                           Hamilton shall not be entitled to any payments after
                           the date of termination and shall forfeit the
                           unvested portion of any stock grant.

                  B.       For purposes of this Agreement, "justifiable cause"
                           shall mean only the following:

                           B1.      The conviction of Hamilton or any of its
                                    principals of a felony involving moral

                                    alcohol abuse, or dishonesty, or any crime
                                    in connection with his provision of services
                                    to the Company that causes the Company a
                                    substantial detriment, but specifically
                                    shall not include traffic offenses, except
                                    the offenses of driving under the influence
                                    of alcohol or any illegal narcotic, or
                                    driving while intoxicated;

                           B2.      Continual neglect of duties specified in
                                    Section 3 or refusal to carry out the lawful
                                    policies of the Company as adopted by the
                                    Board of Directors, provided that in either
                                    event Hamilton has received written notice
                                    from the Board of Directors or management of
                                    the Company of such neglect or refusal and
                                    Hamilton fails to cure such breach within
                                    ten (10) days of receipt of notice;

                           B3.      Hamilton or any of its principals takes
                                    unlawful advantage of a corporate
                                    opportunity, unless: (a) it first offers the
                                    corporate opportunity to the Company and
                                    makes disclosure concerning the conflict of
                                    interest and the corporate opportunity, and
                                    the corporate opportunity is rejected by the
                                    Company in writing in advance; or (b)
                                    Hamilton's taking of the corporate
                                    opportunity is ratified by a majority of
                                    disinterested members of the Board of
                                    Directors; provided also that such taking of
                                    corporate advantage shall not constitute
                                    "justifiable cause" if (i) Hamilton's
                                    failure to offer the corporate opportunity
                                    to the company resulted from a good faith
                                    belief that the business activity did not
                                    constitute a corporate opportunity, and (ii)
                                    not later than fifteen (15) days after
                                    receiving written notice from the Board of
                                    Directors challenging the taking of the
                                    corporate opportunity, the corporate
                                    opportunity is to the extent possible
                                    offered to the Company.

                           B4.      "Justifiable cause" includes disability as
                                    defined herein. For purposes of this
                                    Agreement, Hamilton shall be "disabled" or
                                    under "disability" if, as a result of
                                    incapacity due to physical or mental
                                    illness, N. D. Hamilton shall have been
                                    absent from the substantial performance of
                                    his duties under this Agreement for one
                                    month, and, within 10 days after written
                                    notice of termination is given (which notice
                                    may only be given after the end of the
                                    one-month absence), N. D. Hamilton shall not
                                    have returned to the performance of his
                                    duties under this Agreement, in which event
                                    the Company may terminate Hamilton's
                                    employment under this Agreement for
                                    "disability."

                           B5.      Death of N. D. Hamilton.

<PAGE>

                  C.       If there is a dispute as to whether or not
                           "justifiable cause" shall exist, the parties agree to
                           settle the dispute by arbitration in accordance with
                           the commercial arbitration rules of the American
                           Arbitration Association, and the judgment of the
                           arbitrator(s) may be entered in any court having
                           jurisdiction thereof. Each party agrees to pay all of
                           its own legal fees and costs associated with any
                           legal proceedings concerning the interpretation of
                           this Agreement.

                               WARRANT CERTIFICATE

                WARRANT NUMBER SERIES A - *NUMBER OF WARRANTS: *

            SERIES "A" WARRANT CERTIFICATE FOR THE PURCHASE OF SHARES
                       OF THE NO PAR VALUE COMMON STOCK OF
             MEDIACOMM BROADCASTING SYSTEMS, INC., d/b/a SHOPBIZ.COM

     FOR VALUE RECEIVED, Mediacomm Broadcasting Systems, Inc. (the "Company"), a
Colorado corporation, hereby certifies that *, the registered holder hereof, or
registered assigns (in either case the "Holder") is entitled to purchase,
subject to the terms and conditions hereinafter set forth, at any time beginning
one year after the date hereof and before *, 2005, and not thereafter, one (1)
share of the Common Stock of the Company for each one (1) Warrant exercised at a
price of $2.00 per share of Common Stock and receive a certificate(s) for the
number of shares of Common Stock so purchased upon presentation and surrender of
this Warrant Certificate together with the Form of Subscription, constituting a
part hereof, to the transfer agent of the Company duly executed and accompanied
by payment of the purchase price for all shares purchased, either by certified
check or bank draft, payable to the order of the Company. Fractions of shares of
the Common Stock of the Company will not be issued. Any denominations of money
less that $1.00 paid by the Holder will be retained by the Company.

     The Company covenants and agrees that all shares of Common Stock which may
be delivered upon the exercise of this Warrant will, upon delivery, be free from
all taxes, liens and charges with respect to the purchase thereof. This Warrant
shall not be exercised by Holder in any state where such exercise would be
unlawful such as a state in which the shares of common stock of the Company are
not registered or qualified as the case requires.

     The Company agrees at all times to reserve or hold available a sufficient
number of shares of its Common Stock to cover the number of shares issuable upon
the exercise of this and all other Series "A" Warrants then outstanding.

     This Warrant does not entitle the Holder to any voting rights or other
rights as a shareholder of the Company, or to any other rights whatsoever

<PAGE>

except the rights herein set forth, and no dividend shall be payable or accrue
in respect to this Warrant or the interest represented hereby, or the shares
purchasable hereunder, until or unless, and except to the extent that this
Warrant shall be exercised, and the Common Stock purchasable upon exercise
thereof shall become deliverable.

     The Warrants are not redeemable nor cancelable by the Company.

     This Warrant is exchangeable upon the surrender hereof by the Holder to the
Company for new Warrants of like tenor and date representing in the aggregate
the right to purchase the number of shares purchasable hereunder, each of such
new Warrants to represent the right to purchase such number of shares as many be
designated by the registered owner at the time of such surrender.

     The Company may deem and treat the Holder at any time as the absolute owner
hereof for all purposes and shall not be affected by any notice to the contrary.

     The number of shares of Common Stock purchasable upon the exercise of this
Warrant and the purchase price shall be subject to adjustment from time to time
as follows:

     (1) If the Company shall at any time subdivide its outstanding shares of
Common Stock by recapitalization, reclassification or split-up thereof, or if
the Company shall declare a stock dividend or distribute shares of Common Stock
to its stockholders, the number of shares of Common Stock purchasable upon
exercise of this Warrant immediately prior to such subdivision shall be
proportionately increased in each instance, and if the Company shall at any time
reduce the then outstanding shares of Common Stock by recapitalization,
reclassification or combination thereof, the number of shares of Common Stock
purchasable upon exercise of this Warrant immediately prior to such
recapitalization, reclassification or combination shall be proportionately
decreased in each instance.

     (2) If the Company shall distribute to all of the holders of its shares of
Common Stock any security (except as provided in the preceding paragraph) or
other assets (other than a distribution made as a dividend payable out of
earnings or out of any earned surplus legally available for dividends under the
laws of the jurisdiction of incorporation of the Company), the Board of
Directors of the Company shall make such equitable adjustment in the Warrant
Price in effect immediately prior to the record date of such distribution as may
be necessary to preserve to the Holder of this Warrant rights substantially
proportionate to those enjoyed hereunder by such Holder immediately prior to the
happening of such distribution. Any such adjustment shall become effective as of
the day following the record date for such distribution.

<PAGE>

     (3) Whenever the number of shares of Common Stock purchasable upon the
exercise of this Warrant is required to be adjusted as herein provided, the
Warrant Price shall be adjusted (to the nearest cent) in each instance by
multiplying such Warrant Price immediately prior to such adjustment by a
fraction (x) the numerator of which shall be the number of shares of Common
Stock purchasable upon the exercise of the Warrants immediately prior to such
adjustment, and (y) the denominator of which shall be the number of shares of
Common Stock so purchasable immediately thereafter.

     (4) In case of any reclassification of the outstanding shares of Common
Stock, other than a change covered by paragraph (1) above or which solely
affects the par value of such shares of Common Stock, or in the case of any
merger or consolidation of the Company with or into another corporation (other
that a consolidation merger in which the Company is the continuing corporation
and which does not result in any reclassification or capital reorganization of
the outstanding shares of Common Stock), or in the case of any sale or
conveyance to another corporation of the property of the Company as an entirety
or substantially as an entirety in connection with which the Company is
dissolved, the Holder of this Warrant shall have the right thereafter (until the
expirations of the respective rights of exercise of the Warrant) to receive upon
the exercise thereof, for the same aggregate Warrant Price payable hereunder
immediately prior to such event, the kind and amount of shares of stock or other
securities or property receivable upon such reclassification, capital
reorganization, merger or consolidation, or upon the dissolution following any
sale or other transfer, which a holder of the number of shares of Common Stock
of the Company would obtain upon exercise of the Warrants immediately prior to
such event; and if any classification also results in a change in shares of
Common Stock covered by paragraph (1) above, then such adjustment shall be made
pursuant to both paragraph (1) above and this paragraph (4). The provisions of
this paragraph (4) shall similarly apply to successive reclassifications, or
capital reorganizations, mergers or consolidations, sales or other transfers.

     (5) In case of the dissolution, liquidation or winding-up of the Company,
all rights under any of the Warrants outstanding and not expired by their terms
shall terminate on a date fixed by the Company, such date so fixed to be not
earlier than the date of the commencement of the proceedings for such
dissolution, liquidation or winding-up and not later than thirty (30) days after
such commencement date. Notice of such termination of purchase rights shall be
given to the registered Holder of this Warrant Certificate as the same shall
appear on the books of the Company, by certified or registered mail at least
thirty (30) days prior to such termination date.

     (6) In case the Company shall, at any time prior to the Expiration Date of
the Warrants, and prior to the exercise thereof, offer to the holders of its
Common Stock any right to subscribe for additional shares of any class of

<PAGE>

securities of the Company, then the Company shall give written notice thereof to
the registered Holder of this Warrant Certificate not less than thirty (30) days
prior to the date on which the books of the Company are closed or a record date
fixed for the determination of stockholders entitled to such subscription
rights. Such notice shall specify the date as to which the books shall be closed
or record date be fixed with respect to such offer or subscription, and the
rights of the Holder of this warrant to participate in such offer or
subscription shall terminate if this Warrant shall not be exercised on before
one day prior to the date of such closing of the books or such record date.

     IN WITNESS WHEREOF, the Company has caused this Warrant to be executed by
its duly authorized officer this * day of * 1999.
