                          COMMON STOCK PURCHASE WARRANT

Date of Issuance:  __________, 2001           Warrant Certificate No. CN-_______


For value received, Interactive Network, Inc., a California corporation (the
"Company"), hereby grants to ___________ or his or its registered assigns (the
"Initial Holder") the right to purchase from the Company (the "Purchase Rights")
up to an aggregate of _____ shares (the "Shares") of the Company's Common Stock
at an initial exercise price ("Initial Exercise Price") of $0.60 per share. The
number of Shares and the Initial Exercise Price of this Warrant are subject to
adjustment pursuant to the provisions contained in this Warrant. (The terms
"Registered Holder" or "Registered Holders" shall mean herein the Initial
Registered Holder and any other Persons to which all or part of this Warrant has
been duly transferred pursuant to the terms of this Warrant.) This Warrant is
one of a series of warrants (the "Bridge Warrants") issued by the Company in its
offering of units beginning in June 2001, with each unit consisting of a
convertible promissory note in the original principal amount of $10,000.00 and a
Bridge Warrant to purchase 20,000 shares of Common Stock. Certain capitalized
terms used herein are defined in Section 3 hereof.

This Warrant is subject to the following provisions:

Section 1.  Exercise of Warrant.
            -------------------

         1.1 EXERCISE PERIOD. Subject to the provisions of Section 6 hereof, the
Purchase Rights may be exercised in whole or in part (but not as to a fractional
share of Common Stock) at any time beginning on the Date of Issuance and ending
at 5:00 o'clock p.m., Pacific time, on ____________, 2006 (the "Exercise
Period"). To the extent not exercised during the Exercise Period, the Purchase
Rights shall expire and shall not be exercisable after such Exercise Period.

         1.2 EXERCISE PROCEDURE.

                  (a) Subject to the provisions of Section 8 hereof, the
                  Purchase Rights will be deemed to have been exercised when the
                  Company has received, examined, and accepted all of the
                  following items (the "Exercise Time"):

                           (i) a duly completed and signed Exercise Agreement,
                           as described in Section 1.3 of this Agreement,
                           executed by the person exercising such Purchase
                           Rights (the "Purchaser");

                           (ii) this Warrant;

                                       18
<PAGE>

                           (iii) if this Warrant is not registered in the name
                           of the Purchaser, a duly completed and signed
                           Assignment or Assignments in the form set forth in
                           EXHIBIT II evidencing the assignment of this Warrant
                           to the Purchaser, in which case the Registered Holder
                           will have complied with the provisions set forth in
                           Section 6 hereof;

                           (iv) a certified, cashier's or bank check or, in the
                           sole discretion of the Company, a personal check, in
                           an amount equal to the product of the Exercise Price
                           (as defined in Section 2) multiplied by the number of
                           Shares of Common Stock being purchased upon such
                           exercise; and

                           (v) an opinion of counsel as described in Section 6.2
                           hereof that the exercise of this Warrant is
                           permissible under applicable securities laws.

                  (b) Certificates evidencing the Shares of Common Stock
                  purchased upon exercise of the Purchase Rights will be
                  delivered by the Company to the Purchaser within fifteen (15)
                  days after the date of the Exercise Time. Unless all of the
                  Purchase Rights have expired or have been exercised, the
                  Company will prepare a new Warrant, substantially identical
                  hereto, representing the Purchase Rights formerly represented
                  by this Warrant which have not expired or been exercised and
                  will, within such fifteen (15) day period, deliver such new
                  Warrant to the Person duly designated for delivery in the
                  Exercise Agreement described in Section 1.2(a)(i).

                  (c) The Shares of Common Stock issuable upon the exercise of
                  the Purchase Rights will be deemed to have been issued to the
                  Purchaser at the Exercise Time, and the Purchaser will be
                  deemed for all purposes to have become the record holder of
                  such Shares at the Exercise Time.

                  (d) The issuance of certificates evidencing Shares of Common
                  Stock acquired upon exercise of the Purchase Rights will be
                  made without charge to the Registered Holders or the
                  Purchasers for any issuance tax or other cost incurred by the
                  Company in connection with such exercise and the related
                  issuance of Shares of Common Stock. Each Share of Common Stock
                  issuable upon exercise of the Purchase Rights will, upon
                  payment of the Exercise Price therefor, be fully paid and
                  nonassessable and free from all liens and charges with respect
                  to the issuance thereof, except such as may have been created
                  or caused by the Registered Holder or Purchaser.

                  (e) The Company will not close its books against the transfer
                  of this Warrant or of any share of Common Stock issued or
                  issuable upon the exercise of the Purchase Rights in any
                  manner which interferes with the timely exercise of the
                  Purchase Rights. The Company will from time to time take all
                  such action as may be necessary to assure that the par value
                  per share of the unissued Common Stock acquirable upon
                  exercise of the Purchase Rights is at all times equal to or
                  less than the Exercise Price then in effect.

         1.3 EXERCISE AGREEMENT. Upon any exercise of the Purchase Rights, the
Purchaser shall duly complete, sign, and deliver to the Company an Exercise
Agreement in the form set forth in EXHIBIT I, and, in addition, if the Shares of
Common Stock are not to be issued in the name of the Person in whose name this
Warrant is registered, the Exercise Agreement also will state the name of the
Person to whom the certificates for the Shares of Common Stock are to be issued,
and if the number of Shares of Common Stock to be issued does not include all
the Shares of Common Stock purchasable hereunder, it will also state the name of
the Person to whom a new Warrant for the unexercised portion of the Purchase
Rights is to be delivered. Such Exercise Agreement will be dated the actual date
of execution thereof.

         1.4 FRACTIONAL SHARES. If a fractional Share of Common Stock would, but
for the provision of Section 1.1 hereof, be issuable upon exercise of the
Purchase Rights, the Company will, within fifteen (15) business days after the
date of the Exercise Time deliver to the Purchaser a check payable to the
Purchaser in lieu of such fractional share in an amount equal to the difference
between the Market Price of such fractional share as of the date of the Exercise
Time and the Exercise Price of such fractional share.

                                       19
<PAGE>

         1.5 RESERVATION OF SHARES. The Company shall reserve, out of the
authorized and unissued shares of Common Stock, a number of shares sufficient to
provide for the exercise of the Purchase Rights represented by this Warrant, and
the Company and its transfer agent, if any, are hereby irrevocably authorized
and directed at all times until the expiration of the Purchase Rights to reserve
such number of authorized and unissued shares as shall be requisite for such
purpose. The Company will supply its transfer agent with duly executed stock
certificates for such purpose. The Company will furnish to its transfer agent a
copy of all notices of adjustments, and certificates related thereto,
transmitted pursuant to this Warrant.

Section 2.  Adjustment of Exercise Price and Number of Shares.
            -------------------------------------------------

To prevent dilution of the Purchase Rights, the Initial Exercise Price of any
Purchase Rights, or the Initial Exercise Price as adjusted pursuant to this
Section 2, shall be subject to adjustment from time to time as provided in this
Section 2 (the Initial Exercise Price or the Initial Exercise Price as last
adjusted pursuant to the terms of this Section 2, as the case may be, is called
the "Exercise Price"), and the number of Shares of Common Stock obtainable upon
exercise of the Purchase Rights shall be subject to adjustment from time to time
as provided in this Section 2.

         2.1 SUBDIVISION OR COMBINATION OF COMMON STOCK. If the Company at any
time subdivides (by any stock split, stock dividend or otherwise) one or more
classes of its outstanding shares of Common Stock into a greater number of
shares, the Exercise Price of all Purchase Rights in effect immediately prior to
such subdivision will be proportionately reduced, and the number of Shares of
Common Stock obtainable upon exercise of such Purchase Rights will be
proportionately increased. If the Company at any time combines (by reverse stock
split or otherwise) one or more classes of its outstanding shares of Common
Stock into a smaller number of shares, the Exercise Price of all Purchase Rights
in effect immediately prior to such combination will be proportionately
increased, and the number of Shares of Common Stock obtainable upon exercise of
such Purchase Rights will be proportionately decreased.

         2.2 REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.
Any capital reorganization, reclassification, amalgamation, consolidation,
merger or sale of all or substantially all of the Company's assets to another
Person which is effected in such a way that holders of Common Stock are entitled
to receive (either directly or upon subsequent liquidation) stock, securities or
assets with respect to or in exchange for Common Stock, is referred to herein as
an "Organic Change." Prior to the consummation of any Organic Change, the
Company will make appropriate provision (in form and substance satisfactory to
the registered holders of Bridge Warrants representing a majority of the Common
Stock purchasable upon exercise of the Bridge Warrants (the "Majority Registered
Holders") to insure that each of such registered holders will thereafter have
the right to acquire and receive in lieu of or addition to the Shares of Common
Stock immediately theretofore acquirable and receivable upon the exercise of the
Purchase Rights of all of the Bridge Warrants such shares of stock, securities
or assets as may be issued or payable with respect to or in exchange for the
number of Shares of Common Stock immediately theretofore acquirable and
receivable upon exercise of the Purchase Rights of all of the Bridge Warrants
had such Organic Change not taken place. In any such case, the Company will make
appropriate provision (in form and substance satisfactory to the Majority
Registered Holders) with respect to the Registered Holder's rights and interests
to insure that the provisions of this Section 2 will thereafter be applicable to
this Warrant. The Company will not effect any such amalgamation, consolidation,
merger or sale unless, prior to the consummation thereof, the successor
corporation (if other than the Company) resulting from such amalgamation,
consolidation or merger or the corporation purchasing such assets assumes by
written instrument (in form and substance satisfactory to the Majority
Registered Holders) the obligation to deliver to each such holder such shares of
stock, securities or assets as, in accordance with the foregoing provisions,
such holder may be entitled to acquire.

         2.3 CERTAIN DISTRIBUTIONS. If the Company shall distribute to all
holders of its shares of Common Stock notes or other evidence of indebtedness or
assets (other than cash dividends not in excess of the Company's earnings for
the immediately preceding fiscal year) or Options or Convertible Securities,
then in each case the number of Shares of Common Stock thereafter obtainable
upon the exercise of the Purchase Rights shall be determined by multiplying the
number of Shares theretofore obtainable upon such exercise by a fraction, of
which the numerator shall be the then current Market Price per share of Common
Stock on the date of such distribution, and of which the denominator shall be
the then current Market Price per share of Common Stock, less the then current
Market Price of the portion of the assets, notes or other evidence of
indebtedness so distributed or of such Options or Convertible Securities
applicable to one share of Common Stock. Such adjustment shall be made whenever

                                       20
<PAGE>

any such distribution is made, and shall become effective on the date of
distribution retroactive to the record date for the determination of
shareholders entitled to receive such distribution. In the event of a
distribution by the Company to all holders of its shares of Common Stock of
stock of a Subsidiary or securities convertible into or exercisable for such
stock, then in lieu of an adjustment in number of Shares of Common Stock
acquirable upon the exercise of the Purchase Rights, the Registered Holder of
this Warrant, upon the exercise thereof at any time after such distribution,
shall be entitled to receive from the Company, such Registered Subsidiary, or
both, as the Company shall determine, the stock or other securities to which
such Registered Holder would have been entitled if such Registered Holder had
exercised the Purchase Rights immediately prior thereto.

         2.4 CERTAIN EVENTS.

                  (a) ADJUSTMENT. If any event occurs of the type contemplated
                  by the provisions of this Section 2 but not expressly provided
                  for by such provisions, then the Company's board of directors
                  will make an appropriate adjustment in the Exercise Price and
                  the number of Shares of Common Stock obtainable upon exercise
                  of the Purchase Rights so as to protect the rights of the
                  Registered Holders of the Warrants.

                  (b) NO IMPAIRMENT. The Company will not, by amendment of its
                  charter or bylaws or through any Organic Change or other
                  reorganization, amalgamation, transfer of assets,
                  reclassification, merger, dissolution, issue or sale of
                  securities, or otherwise, avoid or seek to avoid the
                  observance or performance of any of the terms to be observed
                  or performed by the Company under this Warrant but will at all
                  times in good faith assist in the carrying out of all the
                  provisions of this Warrant and in the taking of all such
                  actions as may be necessary or appropriate in order to protect
                  the rights of the Registered Holders of this Warrant against
                  impairment.

         2.5 NOTICES.

                  (c) Immediately upon any adjustment of the Exercise Price or
                  number of Shares subject to this Warrant, the Company will
                  give written notice thereof to each Registered Holder.

                  (d) The Company will give written notice to the Registered
                  Holder at least fifteen (15) business days prior to the date
                  on which the Company closes its books or takes a record with
                  respect to any dividend or distribution upon the Common Stock,
                  with respect to any pro rata subscription offer to holders of
                  Common Stock, or for determining rights to vote with respect
                  to any Organic Change, dissolution or liquidation.

                  (e) The Company also will give written notice to the
                  Registered Holders at least fifteen (15) business days prior
                  to the date on which any Organic Change, dissolution or
                  liquidation will take place.

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

This Warrant does and will not entitle the Registered Holder(s) hereof to any

Section 6.  Conditions to Exercise or Transfer of Warrant.
            ---------------------------------------------

         6.1 TRANSFER OF WARRANT. Subject to the conditions referred to in the
legend endorsed hereon and as hereinafter set forth, this Warrant and all rights
hereunder are transferable, in whole or in part, without charge to the
Registered Holder, upon surrender of this Warrant with a properly executed
Assignment (in the form of EXHIBIT II hereto) at the principal office of the
Company.

         6.2 CONDITIONS TO TRANSFER. The Registered Holder, by acceptance
hereof, agrees to give written notice to the Company before transferring this
Warrant or any part hereof, or before transferring any Common Stock issued upon
the exercise hereof, of the Registered Holder's intention to do so, describing
briefly the manner of any proposed transfer. Promptly upon receiving such
written notice, or promptly upon receiving from the Registered Holder the items
described in Sections 1.2(a)(i) through (iv) hereof, the Company shall present

                                       22
<PAGE>

copies thereof to the Company's counsel. If, in the opinion of such counsel, the
proposed exercise or transfer may be effected without registration or
qualification of the Warrant or the Shares of Common Stock purchasable upon the
exercise hereof, under any federal, state, or territorial securities laws, the
Company, as promptly as practicable, shall notify the Registered Holder of such
opinion. The Registered Holder then shall be entitled to exercise or transfer
this Warrant or any part hereof or to dispose of Shares of Common Stock received
upon the previous exercise of this Warrant in accordance with the terms of the
notice delivered by the Registered Holder to the Company; provided, however,
that an appropriate legend may be endorsed on the Warrant or the certificates
evidencing the Shares of Common Stock purchasable upon exercise of the Warrant,
which legend sets forth the restrictions upon the transfer thereof necessary or
advisable in the opinion of counsel satisfactory to the Company to prevent
further transfers which would be in violation of Section 5 of the Securities Act
of 1933, as amended, and applicable state or territorial securities laws. If, in
the opinion of the counsel referred to in this Section, the proposed exercise or
transfer or disposition of the Warrant or Shares described in the written notice
given pursuant to this Section may not be effected without registration or
qualification of this Warrant or the Shares of Common Stock issued upon the
exercise hereof, the Company shall promptly give written notice thereof to the
Registered Holder, and the Registered Holder will limit and conduct his
activities in respect to such as, in the opinion of such counsel, are permitted
by law.

Section 7.  Right to Convert.
            ----------------

         7.1 CONVERSION RIGHT. The Registered Holder shall have the right to
require the Company to convert this Warrant (the "Conversion Right"), at any
time prior to its expiration, into shares of Common Stock as provided for in
this Section. Upon exercise of the Conversion Right, the Company shall deliver
to the Registered Holder (without payment by the Registered Holder of any
exercise price) that number of shares of Common Stock equal to the quotient
obtained by dividing (i) the value of the Warrant at the time the Conversion
Right is exercised (determined by subtracting the aggregate exercise price for
the Shares in effect immediately prior to the exercise of the Conversion Right
from the aggregate Market Price for the Shares immediately prior to the exercise
of the Conversion Right) by (ii) the Market Price of one share of Common Stock
immediately prior to the exercise of the Conversion Right.

         7.2 EXERCISE OF CONVERSION RIGHT. The Conversion Right may be exercised
by the Registered Holder, at any time or from time to time, prior to its
expiration, on any business day, by delivering a written notice (the "Conversion
Notice"), the form of which is attached hereto as EXHIBIT III, to the Company at
the offices of the Company exercising the Conversion Right and specifying (i)
the total number of Shares the Registered Holder will purchase pursuant to such
conversion, and (ii) a place, and a date not less than five (5) nor more than
twenty (20) trading days from the date of the Conversion Notice, for the closing
of such purchase.
