NEITHER THIS WARRANT NOR THE COMMON SHARES ISSUABLE UPON THE EXERCISE OF THIS
WARRANT HAVE BEEN QUALIFIED UNDER THE SECURITIES LAWS OF ANY OF THE PROVINCES OF
CANADA. FOR THE PURPOSES OF THE SECURITIES ACT (BRITISH COLUMBIA), THIS WARRANT
AND THE COMMON SHARES ISSUABLE UPON THE EXERCISE OF THIS WARRANT ARE SUBJECT TO
A HOLD PERIOD AND MAY NOT BE TRADED IN BRITISH COLUMBIA UNTIL AFTER THE EXPIRY
OF THE HOLD PERIOD, EXCEPT AS PERMITTED BY THE SECURITIES ACT (BRITISH COLUMBIA)
AND REGULATIONS MADE THEREUNDER.

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT
OF 1933, AS AMENDED, OR THE SECURITIES ACT OF ANY STATE (COLLECTIVELY, THE
"SECURITIES LAWS"). THEY MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF
AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES LAWS OR AN OPINION OF
COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES THAT AN EXEMPTION UNDER
THE SECURITIES LAWS IS AVAILABLE AND THAT SUCH REGISTRATION IS NOT REQUIRED.

           THIS WARRANT IS NOT TRANSFERABLE AND WILL BE VOID AND OF NO
            VALUE UNLESS EXERCISED WITHIN THE LIMITS HEREIN PROVIDED

                     MDU COMMUNICATIONS INTERNATIONAL, INC.

                            (a Delaware corporation)

           WARRANT FOR THE PURCHASE OF 309,000 SHARES OF COMMON STOCK

THIS IS TO CERTIFY THAT, for value received, HAYWOOD SECURITIES INC. (the
"Holder") is entitled to subscribe for and purchase 309,000 fully paid and
non-assessable shares of the Common Stock (the "Common Shares") of MDU
Communications International, Inc. (the "Company") at a purchase price per share
(the "Exercise Price") of US$2.50. This Warrant is exercisable at any time up to
4:00 P.M. Vancouver time on January 28, 2001 (the "Time of Expiry") subject,
however, to the provisions and adjustments and upon the terms and conditions
hereinafter set forth.

The rights represented by this Warrant may be exercised by the Holder, in whole
or in part (but not as to a fractional Share), by surrender of this Warrant at
the office of the Company at 108 - 11951 Hammersmith Way, Richmond, B.C.
V7A 5H9, during its normal business hours, together with the subscription form
attached hereto completed and signed by the Holder and a certified cheque
payable to or to the order of the Company in payment of the Exercise Price for
the number of Common Shares subscribed for. Upon the exercise of the rights
represented by this Warrant and payment of the Exercise Price in accordance with
the terms hereof, the Common Shares for which the Holder has subscribed and
purchased shall be deemed to have been issued and the Holder shall be deemed to
have become the holder of record of such shares on the date of such exercise and
payment.


<PAGE>

In the event of any exercise of the rights represented by this Warrant,
certificates for the Common Shares so purchased shall be delivered to the Holder
within a reasonable time, not exceeding two business days after the rights
represented by this Warrant have been duly exercised and, unless this Warrant
has expired, a new Warrant representing the number of Common Shares, if any,
with respect to which this Warrant shall not then have been exercised shall also
be issued to the Holder within such time.

The Company covenants and agrees that the Common Shares which may be issued upon
the due exercise of the rights represented by this Warrant will, upon issuance,
be fully paid and non-assessable and free of all liens, charges and
encumbrances. The Company further covenants and agrees that during the period
within which the rights represented by this Warrant may be exercised, the
Company will at all times have authorized and reserved, a sufficient number of
Common Shares to provide for the exercise of the rights represented by this
Warrant.

                   THE FOLLOWING ARE THE TERMS AND CONDITIONS
                           REFERRED TO IN THIS WARRANT

1.   In case the Company shall at any time subdivide its outstanding Common
Shares into a greater number of shares, the Exercise Price shall be
proportionately reduced and the number of subdivided Common shares entitled to
be purchased proportionately increased, and conversely, in case the outstanding
Common Shares of the Company shall be consolidated into a smaller number of
shares, the Exercise Price shall be proportionately increased and the number of
consolidated Common Shares entitled to be purchased hereunder shall be
proportionately decreased.

     If any capital reorganization or reclassification of the capital stock of
the Company, or the merger, amalgamation or arrangement of the Company with
another corporation shall be effected, then as a condition of such
reorganization, reclassification, merger, amalgamation or arrangement, adequate
provision shall be made whereby the holder hereof shall have the right to
purchase and receive upon the basis and upon the terms and conditions specified
in this Warrant and in lieu of the Common Shares immediately theretofore
purchasable and receivable upon the exercise of the rights represented hereby,
such shares of stock, or other securities as may be issued with respect to or in
exchange for such number of outstanding Common Shares equal to the number of
Common Shares purchasable and receivable upon the exercise of this Warrant had
such reorganization, reclassification, merger, amalgamation or arrangement not
taken place. The Company shall not effect any merger, amalgamation or
arrangement unless prior to or simultaneously with the consummation thereof the
successor corporation (if other than the Company) resulting from such merger,
amalgamation or arrangement assumes by written instrument executed and mailed or
delivered to the holder of this Warrant the obligation to deliver to such holder
such shares of stock or securities in accordance with the foregoing provisions
as such holder may be entitled to purchase.


                                       6

2.   In case at any time:

     (a)  the Company shall pay any dividend payable in stock upon its Common
          Shares or make any distribution to the holders of its Common Shares;

     (b)  the Company shall offer for subscription pro rata to the holders of
          its Common Shares any additional shares of stock of any class or other
          rights;

     (c)  there shall be any subdivision, consolidation, capital reorganization,
          or reclassification of the capital stock of the Company, or merger,
          amalgamation or arrangement of the Company with, or sale of all or
          substantially all of its assets to, another corporation; or

     (d)  there shall be a voluntary or involuntary dissolution, liquidation or
          winding-up of the Company;

then, and in any one or more of such cases, the Company shall give to the holder
of this Warrant, at least twenty day's prior written notice of the date on which
the books of the Company shall close or a record shall be taken for such
dividend, distribution or subscription rights, or for determining rights to vote
with respect to such subdivision, consolidation, reorganization,
reclassification, merger, amalgamation, arrangement, dissolution, liquidation or
winding-up and in the case of any such subdivision, consolidation,
reorganization, reclassification, merger, amalgamation, arrangement, sale,
dissolution, liquidation or winding-up, at least twenty days' prior written
notice of the date when the same shall take place. Such notice in accordance
with the foregoing clause, shall also specify, in the case of any such dividend,
distribution or subscription rights, the date on which the holders of Common
Shares shall be entitled thereto, and such notice in accordance with the
foregoing shall also specify the date on which the holders of Common Shares
shall be entitled to exchange their Common Shares for securities or other
property deliverable upon such subdivision, consolidation, reorganization,
reclassification, merger, amalgamation, arrangement, sale, dissolution,
liquidation or winding-up as the case may be. Each such written notice shall be
given by first class mail, registered postage prepaid, addressed to the holder
of this Warrant at the address of such holder, as shown on the books of the
Company.

3.   As used herein, the term "Common Shares" shall mean and include the
Company's authorized shares of Common Stock as constituted on January 28, 2000,
and shall also include any capital stock of any class of the Company hereafter
authorized which shall not be limited to a fixed sum or percentage in respect of
the rights of the holders thereof to participate in dividends and in the
distribution of assets upon the voluntary or involuntary liquidation,
dissolution or winding-up of the Company.

4.   This Warrant shall not entitle the Holder to any rights as a shareholder of
the Company, including without limitation, voting rights, except that the
Company shall concurrently furnish to the Holder a copy of all notices which are
furnished to holders of the common shares.

5.   This Warrant and all rights hereunder are not transferable.

6.   On presentation at the principal office of the Company in Richmond, British
Columbia one or more Warrant Certificates may be exchanged for one or more
Warrant Certificates of different denominations evidencing in the aggregate the
same number of Warrants as the Warrant Certificate or Warrant Certificates being
exchanged.
