Item 1. Description of Registrant's Securities to be Registered.

     This amendment no. 2 to the registration statement on Form 8-A/A amends the
registration statement on Form 8-A that MDU Resources Group, Inc. filed on
September 21, 1994, as amended by amendment no. 1 on Form 8-A/A filed on March
23, 2000.

                           DESCRIPTION OF COMMON STOCK

     General

     The following is a description of our common stock. This description is not
complete, and we qualify this description by referring to our restated
certificate of incorporation, as amended, amended bylaws, indenture of mortgage,
all of which we incorporate herein by reference or file herewith, and the laws
of the state of Delaware. We also refer to the rights agreement, dated as of
November 12, 1998, that we entered into with Wells Fargo Bank Minnesota, N.A.
(formerly known as Norwest Bank Minnesota, N.A.), as rights agent, that we
incorporate herein by reference.

     Our restated certificate of incorporation authorizes us to issue
252,000,000 shares of stock, divided into four classes:

     o    500,000 shares of preferred stock, $100 par value
     o    1,000,000 shares of preferred stock A, without par value
     o    500,000 shares of preference stock, without par value and
     o    250,000,000 shares of common stock, $1.00 par value.

     Dividend Rights

     Under our restated certificate of incorporation, we may declare and pay
dividends on our common stock, out of our surplus or net profits, only if we
have paid or provided for full cumulative dividends on all outstanding shares of
our preferred and preference stock. As of March 7, 2003, we have no preference
stock outstanding.

     In addition to these provisions, our first mortgage bond indenture includes
a covenant generally to the effect that we may declare and pay dividends in cash
or property on our common stock only either (1) out of our "surplus" or (2) in
case there is no "surplus," out of our net profits for the fiscal year in which
the dividend is declared and/or the preceding fiscal year. For purposes of this
test, "surplus" means the excess of our net assets over our "capital"; and
"capital" means that part of the consideration received by us for any of our
shares of common stock which has been determined to be "capital."

     Voting Rights

     Our common stock has one vote per share. The holders of our common stock
are entitled to vote on all matters to be voted on by stockholders. The holders
of our common stock do not have cumulative voting rights.


                                       2




     The holders of the preferred stock, preferred stock A and preference stock
do not have the right to vote, except as our board of directors establishes or
as provided in our restated certificate of incorporation or bylaws or as
determined by state law.

     The restated certificate of incorporation gives the holders of the
preferred stock and the preferred stock A, or the preference stock, the right to
vote if dividends are unpaid, in whole or in part, on their shares for one year.
The holders have one vote per share until we pay the dividend arrearage, declare
dividends for the current dividend period and set aside the funds to pay the
current dividends. In addition, the holders of certain series of the preferred
stock and preferred stock A, and/or the holders of the preference stock, must
approve certain amendments to the restated certificate of incorporation.

     Liquidation Rights

     If we should liquidate, the holders of the preferred stock, preferred stock
A and the preference stock have the right to receive certain amounts, as set
forth in our restated certificate of incorporation, before we can make any
payments to the holders of our common stock. After the preferred and preference
stock payments are made, the holders of our common stock are entitled to share
in all our remaining assets available for distribution to stockholders.

     Other Rights

     Our common stock is not liable to further calls or assessment. The holders
of our common stock have no preemptive rights. Our common stock cannot be
redeemed, and it does not have any conversion rights or sinking fund provisions.

     Effects on Our Common Stock If We Issue Preferred or Preference Stock

     Our board of directors has the authority, without further action by the
stockholders, to issue up to 500,000 shares of preferred stock, 1,000,000 shares
of preferred stock A and 500,000 shares of preference stock, each in one or more
series. The board of directors has the authority to determine the terms of each
series of any preferred or preference stock, within the limits of the restated
certificate of incorporation and the laws of the state of Delaware. These terms
include the number of shares in a series, dividend rights, liquidation
preferences, terms of redemption, conversion rights and voting rights.

     If we issue any preferred or preference stock, it may negatively affect the
holders of our common stock. These possible negative effects include diluting
the voting power of shares of our common stock and affecting the market price of
our common stock. In addition, the ability of our board of directors to issue
preferred or preference stock may delay or prevent a change in control of MDU
Resources Group, Inc.

     There are 163,000 shares of preferred stock currently outstanding, and we
have reserved 125,000 shares of Series B preference stock for issuance in
connection with our rights plan.

                    PROVISIONS OF OUR RESTATED CERTIFICATE OF
                          INCORPORATION AND OUR BYLAWS
                 THAT COULD DELAY OR PREVENT A CHANGE IN CONTROL

     Our restated certificate of incorporation and bylaws contain certain
provisions which will make it difficult to obtain control of MDU Resources
Group, Inc. if our board of directors does not approve the transaction. The
provisions include the following:

     Provisions Relating to Our Board of Directors

          Classified Board

     We have divided the members of our board of directors into three classes as
nearly equal in number as may be possible. Directors in each class are elected
for a three-year term.

     This classification of the board of directors may prevent stockholders from
changing the membership of the entire board of directors in a relatively short
period of time. At least two annual meetings, instead of one, generally will be
required to change the majority of directors. The classified board provisions
could have the effect of prolonging the time required for a stockholder with
significant voting power to gain majority representation on the board of
directors. Where majority or supermajority board of directors approval is
necessary for a transaction, such as an interested stockholder business
combination, the inability immediately to gain majority representation on the
board of directors could discourage takeovers and tender offers.

          Number of Directors, Vacancies, Removal of Directors

     The restated certificate of incorporation provides that the board of
directors will have at least six and at most 15 directors. Two-thirds of the
continuing directors decide the exact number of directors at a given time. The
board fills any new directorships it creates and any vacancies.

     Directors may be removed only for cause and then only by a majority of the
shares entitled to vote.

     Meetings of Stockholders

          No Cumulative Voting

     The restated certificate of incorporation does not provide for cumulative
voting.

          Advance Notice Provisions

     The bylaws require that for a stockholder to nominate a director or bring
other business before an annual meeting, the stockholder must give notice not
less than 120 days prior to the date corresponding to the date on which we first
mailed our proxy materials for the prior year's annual meeting.


                                       4




     The restated certificate of incorporation prevents stockholders from
calling a special meeting. In addition, the restated certificate of
incorporation provides that stockholder action may be taken only at a
stockholders' meeting.

     Amendment of Restated Certificate of Incorporation

     The restated certificate of incorporation requires the affirmative vote of
80% of the common stock entitled to vote in order to amend certain provisions,
including provisions relating to the board of directors, unless two-thirds of
the continuing directors approve such amendment.

     Provisions Relating to the Authorization of Certain Business Combinations

     The restated certificate of incorporation requires the affirmative vote of
80% of the common stock entitled to vote for directors in order to authorize
certain business combinations. Any business combination must also meet certain
fair price and procedural requirements. However, if two-thirds of the continuing
directors approve the business combination, then the vote of 80% of the common
stock and the fair price provisions will not be required.

     There is also a provision permitting the board of directors to consider
certain specified factors in determining whether or not to approve certain
business combinations.

                        PREFERENCE SHARE PURCHASE RIGHTS

     On November 12, 1998, the board of directors declared a dividend of one
preference share purchase right for each share of our common stock outstanding
as of December 1, 1998. We will issue one right with each additional share of
common stock we issue until the rights expire, are redeemed or exchanged or
become exercisable. The description of our preference share purchase rights is
contained in the Form 8-A/A dated March 23, 2000 and in the rights agreement,
dated November 12, 1998, between Wells Fargo Bank Minnesota, N.A., as rights
agent, and us. We incorporate these documents herein by reference.

                   PROVISIONS OF DELAWARE LAW THAT COULD DELAY
                         OR PREVENT A CHANGE IN CONTROL

     We are subject to the provisions of Section 203 of the General Corporation
Law of Delaware. Subject to certain exceptions, this law prohibits us from
engaging in certain business combinations with a person who owns 15% or more of
our outstanding voting stock for a three-year period after the person acquires
the stock. This prohibition does not apply if our board of directors approved of
the business combination or the acquisition of our stock before the person
acquired 15% of the stock. A business combination includes mergers,
consolidations, stock sales, asset sales and other transactions resulting in a
financial benefit to the interested stockholder.
