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

                        WARRANT TO PURCHASE COMMON STOCK

     This is to certify that, for value received and subject to the terms and
conditions set forth below, _________________________, is entitled to
purchase at any time on or after ___________ and on or before ___________,
and MDU Communications International, Inc., a Delaware corporation ("the
Company"), promises and agrees to sell and issue, up to _______ shares of
Common Stock (hereinafter defined) at a price of ________ (US$_____) per
share ("Exercise Price").

     This Warrant is issued subject to the following terms and conditions:

     1.   DEFINITIONS. Except as may be otherwise clearly required by the
context, the following terms shall have the following meanings:

          "COMMON STOCK" means the Common Stock of the Company.

          "COMPANY" means MDU Communications International, Inc., a Delaware
     corporation.

          "EXERCISE PRICE" means the price at which a Warrant Holder may
     purchase one share of Common Stock (or Securities obtainable in lieu of one
     share of Common Stock) upon exercise of Warrants as determined from time to
     time pursuant to the provisions hereof.

          "SECURITIES" means the Common Stock or other securities obtained or
     obtainable upon exercise of the Warrants.

          "WARRANT HOLDER" means the person named in the initial paragraph of
     this certificate or any successor who is a record holder of Warrants.

          "WARRANTS" means the warrants evidenced by this certificate or by any
     certificate obtained upon transfer or partial exercise of Warrants.


<PAGE>


     2.   EXERCISE OF WARRANTS. All or any part of the Warrants may be
exercised by surrendering this certificate, together with appropriate
instructions, duly executed by the Warrant Holder, or by its duly authorized
attorney, at the office of the Company, 108 - 11951 Hammersmith Way,
Richmond, British Columbia, Canada, or at such other office or agency as the
Company may designate by written notice to the Warrant Holder, accompanied by
payment in full, in lawful money of the United States of the Exercise Price
payable for the Securities being issued on exercise of such Warrants. If
fewer than all the Warrants evidenced by this certificate are exercised, the
Company will, upon such exercise, execute and deliver to the Warrant Holder a
new certificate (dated the date hereof), in form and tenor substantially
similar to this certificate, evidencing the Warrants not exercised. The
Securities to be obtained on exercise of the Warrants shall be deemed to have
been issued, and any person exercising the Warrants shall be deemed to have
become a holder of record of those Securities, as of the date of the
surrender of this certificate and the payment of the Exercise Price.

     3.   ADJUSTMENTS IN CERTAIN EVENTS. The number, class and Exercise Price
of Securities for which this certificate may be exercised are subject to
adjustment from time to time upon the happening of certain events as follows:

          (a)  STOCK DIVIDENDS, SPLITS, ETC. If the outstanding shares of the
Company's Common Stock are divided into a greater number of shares or a
dividend in stock is paid on the Common Stock, the number of shares of Common
Stock which may be purchased under this certificate shall be proportionately
increased and the Exercise Price proportionately decreased; and, conversely,
if the outstanding shares of Common Stock are combined into a smaller number
of shares of Common Stock, the number of shares of Common Stock which may be
purchased under this certificate shall be proportionately reduced and the
Exercise Price proportionately increased. The increases and reductions
provided for in this SECTION 3(a) shall be made with the intent and, as
nearly as practicable, the effect that neither the percentage of the total
equity of the Company obtainable on exercise of the Warrants nor the
aggregate Exercise Price for such percentage upon such exercise shall be
affected by any event described in this SECTION 3(a).

          (b)  MERGERS, CONSOLIDATIONS, ETC. In case of any change in the
Common Stock of the Company through merger, consolidation, reclassification,
reorganization, partial or complete liquidation, or other change in the
capital structure of the Company (not including the issuance of additional
shares of Common Stock by the Company other than by stock split or stock
dividend), then, as a condition of the change in the capital structure of the
Company, lawful and adequate provision shall be made so that the holder of
this certificate will have the right thereafter to receive upon the exercise
of the Warrants the kind and amount of shares of stock or other securities or
property to which it would have been entitled if, immediately prior to such
merger, consolidation, reclassification, reorganization, recapitalization, or
other change in the capital structure, it had held the number of shares of
Common Stock obtainable upon the exercise of the Warrants. In any such case,
appropriate adjustment shall be made in the application of the provisions set
forth herein with respect to the rights and interest thereafter of the
Warrant Holder, to the end that the provisions set forth herein shall
thereafter be applicable, as nearly as reasonably may be possible, in
relation to any shares of stock or other property thereafter deliverable upon
the exercise of the Warrants. The Company will not permit any change in its
capital structure described in this SECTION 3(b) to occur unless the issuer
of the shares of stock or other securities to be received by the holder of
this certificate, if not the Company, agrees to be bound by and comply with
the provisions of this certificate.

          (c)  DETERMINATION AND NOTICE OF EXERCISE PRICE. When any
adjustment is required to be made in the number of shares of Common Stock,
Exercise Price, other securities, or the property purchasable upon exercise
of the Warrants as provided in SECTION 3(b), the Company shall promptly
determine the new Exercise Price, number of such shares or other securities
or property purchasable upon exercise of


<PAGE>


the Warrants and (i) prepare and retain on file a statement describing in
reasonable detail the method used in arriving at the new Exercise Price or
number of such shares or other securities or property purchasable upon
exercise of the Warrants and (ii) cause a copy of such statement to be mailed
to the Warrant Holder within sixty (60) days after the date when the event
giving rise to the adjustment occurred.

          (d)  NO FRACTIONAL SHARES. No fractional shares of Common Stock or
other Securities will be issued in connection with the exercise of any
Warrants, but the Company shall pay, in lieu of fractional shares, a cash
payment therefor on the basis of (i) the mean between the bid and asked
prices in the over-the-counter market or the closing price on a national
securities exchange on the day immediately prior to exercise or (ii) such
other means of determining the fair market value of the Common Stock as is
approved by the Company's Board of Directors.

          (e)  ISSUANCE OF PREFERRED SECURITIES, ETC. If preferred securities
of the Company or securities of any subsidiary of the Company are distributed
pro rata to holders of any or all of the Company's Common Stock, such number
of securities shall be distributed to the Warrant Holder upon exercise of his
rights hereunder as such Warrant Holder or assignee would have been entitled
to if this Warrant had been exercised prior to such distribution. The
provisions with respect to adjustment of the Company's Common Stock provided
in this SECTION 3 shall also apply to the preferred securities and securities
of any subsidiary to which the Warrant Holder or his assignee shall be
entitled under this SECTION 3(e).

          (f)  NO ADJUSTMENTS UPON EXERCISE OF WARRANTS. Notwithstanding
anything herein to the contrary, there shall be no adjustment made hereunder
on account of the sale of the Common Stock purchasable upon exercise of the
Warrants.

     4.   RESERVATION OF SHARES. The Company agrees that the number of shares
of Common Stock or other Securities sufficient to provide for the exercise of
the Warrants upon the basis set forth above shall at all times during the
term of the Warrants be reserved for exercise.

     5.   VALIDITY OF SECURITIES. All Securities delivered upon the exercise
of the Warrants shall be duly and validly issued in accordance with their
terms, and the Company will pay all documentary and transfer taxes, if any,
in respect of the original issuance thereof upon exercise of the Warrants.

     6.   INVESTMENT REPRESENTATION. The Warrant Holder represents and
warrants that it has acquired the Warrants, and will acquire the Common Stock
or other Securities, if any, upon exercise of the Warrants, for its own
account for investment and not with a view to the sale or other disposition
of all or any part of the Warrants, Common Stock or other Securities. The
Warrants, and the Common Stock or other Securities acquired or to be acquired
upon exercise of the Warrants, may not be sold, transferred or otherwise
hypothecated unless in the opinion of counsel for the Company the Warrants,
Common Stock or other Securities may be sold, transferred or otherwise
hypothecated without registration under the Act and any applicable state
securities laws.

     An appropriate legend to the foregoing effect and of the type commonly
placed on certificates evidencing privately placed securities may be placed
on all certificates evidencing Securities.

     7.   NO RIGHTS AS A SHAREHOLDER. Except as otherwise provided herein,
the Warrant Holder shall not, by virtue of ownership of Warrants, be entitled
to any rights of a shareholder of the Company but shall, upon written request
to the Company, be entitled to receive such quarterly or annual reports as
the


<PAGE>


Company by mail shall distribute to its shareholders.

     8.   NOTICE. Any notices required or permitted to be given hereunder
shall be in writing and may be served personally or by mail; and if served by
mail, shall be addressed as follows:
