Item
6.                      Indemnification
of Directors and Officers.
Our
bylaws include the following provision:
7.07           Indemnification
of Officers, Directors, Employees and Agents; Insurance.
(a)
The
      Corporation shall indemnify any person who was or is a party or is
      threatened to be made a party to any threatened, pending or
      completed
II-2
action,
      suit or proceeding, whether civil, criminal, administrative or
      investigative (other than an action by or in the right of the Corporation)
      by reason of the fact that such person is or was a director, officer,
      employee or agent of the Corporation, or is or was serving at the request
      of the Corporation as a director, officer, employee or agent of another
      corporation, partnership, joint venture, trust or other enterprise,
      against expenses (including attorneys' fees), judgments, fines and amounts
      paid in settlement actually and reasonably incurred by such person in
      connection with such action, suit or proceeding if such person acted in
      good faith and in a manner such person reasonably believed to be in or not
      opposed to the best interests of the Corporation, and, with respect to any
      criminal action or proceeding, had no reasonable cause to believe such
      person's conduct was unlawful.  The termination of any action,
      suit or proceeding by judgment, order, settlement, conviction, or upon a
      plea of nolo contendere or its equivalent, shall not, of itself, create a
      presumption that the person did not act in good faith and in a manner
      which such person reasonably believed to be in or not opposed to the best
      interest of the Corporation, and, with respect to any criminal action or
      proceeding, had reasonable cause to believe that such person's conduct was
      unlawful.
(b)
The
      Corporation shall indemnify any person who was or is a party or is
      threatened to be made a party to any threatened, pending or completed
      action or suit by or in the right of the Corporation to procure a judgment
      in its favor by reason of the fact that such person is or was a director,
      officer, employee or agent of the Corporation, or is or was serving at the
      request of the Corporation as a director, officer, employee or agent of
      another corporation, partnership, joint venture, trust or other enterprise
      against expenses (including attorneys' fees) actually and reasonably
      incurred by such person in connection with the defense or settlement of
      such action or suit if such person acted in good faith and in a manner
      such person reasonably believed to be in or not opposed to the best
      interests of the Corporation and except that no indemnification shall be
      made in respect of any claim, issue or matter as to which such person
      shall have been adjudged to be liable to the Corporation, unless and only
      to the extent that the Court of Chancery or the court in which such action
      or suit was brought, shall determine upon application that, despite the
      adjudication of liability but in view of all circumstances of the case,
      such person is fairly and reasonably entitled to indemnity for such
      expenses which the Court of Chancery or such other court shall deem
      proper.
(c)
To
      the extent that a present or former director, officer, employee or agent
      of a corporation has been successful on the merits or otherwise in defense
      of any action, suit or proceeding referred to in subsections (a) and (b),
      or in defense of any claim, issue or matter therein, such person shall be
      indemnified against expenses (including attorneys' fees) actually and
      reasonably incurred by such person in connection
  therewith.
II-3
(d)
Any
      indemnification under subsections (a) and (b) of this Section (unless
      ordered by a court) shall be made by the Corporation only as authorized in
      the specific case upon a determination that indemnification of the present
      or former director, officer, employee or agent is proper in the
      circumstances because such person has met the applicable standard of
      conduct as set forth in subsections (a) and (b) of this
      Section.  Such determination shall be made (1) by a majority
      vote of the directors who are not parties to such action, suit or
      proceeding, even though less than a quorum, or (2) by a committee of such
      directors designated by majority vote of such directors, even though less
      than a quorum, or (3) if there are no such directors, or if such directors
      so direct, by independent legal counsel in a written opinion, or (4) by
      the stockholders.
(e)
Expenses
      (including attorneys' fees) incurred by a present or former officer or
      director in defending any civil, criminal, administrative or investigative
      action, suit or proceeding shall be paid by the Corporation in advance of
      the final disposition of such action, suit or proceeding upon receipt of
      an undertaking by or on behalf of the director or officer to repay such
      amount if it shall ultimately be determined that such person is not
      entitled to be indemnified by the Corporation as authorized in this
      Section.  Once the Corporation has received the undertaking, the
      Corporation shall pay the officer or director within 30 days of receipt by
      the Corporation of a written application from the officer or director for
      the expenses incurred by that officer or director.  In the event
      the Corporation fails to pay within the 30-day period, the applicant shall
      have the right to sue for recovery of the expenses contained in the
      written application and, in addition, shall recover all attorneys' fees
      and expenses incurred in the action to enforce the application and the
      rights granted in this Section 7.07.  Expenses (including
      attorneys' fees) incurred by other employees and agents shall be paid upon
      such terms and conditions, if any, as the Board of Directors deems
      appropriate.
(f)
The
      indemnification and advancement of expenses provided by, or granted
      pursuant to, the other subsections of this Section shall not be deemed
      exclusive of any other rights to which those seeking indemnity or
      advancement of expenses may be entitled under any bylaw, agreement, vote
      of stockholders or disinterested directors or otherwise, both as to action
      in such person's official capacity and as to action in another capacity
      while holding such office.
(g)
The
      Corporation may purchase and maintain insurance on behalf of any person
      who is or was a director, officer, employee or agent of the Corporation,
      or is or was serving at the request of the Corporation as a director,
      officer, employee or agent of another corporation, partnership, joint
      venture, trust or other enterprise, against any liability asserted against
      such person and incurred by such person in any such capacity, or arising
      out of such person's status as such, whether or not the Corporation
      would
II-4
have
      the power to indemnify such person against such liability under the
      provisions of this Section.
(h)
For
      the purposes of this Section, references to "the Corporation" include all
      constituent corporations absorbed in a consolidation or merger, as well as
      the resulting or surviving corporation, so that any person who is or was a
      director, officer, employee or agent of such a constituent corporation or
      is or was serving at the request of such constituent corporation as a
      director, officer, employee or agent of another corporation, partnership,
      joint venture, trust or other enterprise, shall stand in the same position
      under the provisions of this Section with respect to the resulting or
      surviving corporation as such person would if such person had served the
      resulting or surviving corporation in the same
capacity.
(i)
For
      purposes of this Section, references to "other enterprises" shall include
      employee benefit plans; references to "fines" shall include any excise
      taxes assessed on a person with respect to any employee benefit plan; and
      references to "serving at the request of the Corporation" shall include
      any service as a director, officer, employee or agent of the Corporation
      which imposes duties on, or involves services by, such director, officer,
      employee or agent with respect to an employee benefit plan, its
      participants or beneficiaries; and a person who acted in good faith and in
      a manner such person reasonably believed to be in the interest of the
      participants and beneficiaries of an employee benefit plan shall be deemed
      to have acted in a manner "not opposed to the best interests of the
      Corporation" as referred to in this Section.
(j)
The
      indemnification and advancement of expenses provided by, or granted
      pursuant to, this Section shall, unless otherwise provided when authorized
      or ratified, continue as to a person who has ceased to be a director,
      officer, employee or agent and shall inure to the benefit of the heirs,
      executors and administrators of such a
person.
Section
145 of the General Corporation Law of the State of Delaware provides for
indemnification of our directors and officers in a variety of circumstances,
which may include liabilities under the Securities Act of 1933.  We
maintain liability insurance protecting us, as well as our directors and
officers, against liability by reason of their being or having been our
directors or officers.

Previously filed and incorporated herein by reference.
We will
submit or have submitted the MDU Resources Group, Inc. 401(k) Plan and any
amendment thereto to the Internal Revenue Service (the "IRS") in a timely manner
and have made or will make all changes required by the IRS in order to qualify
the plan, as amended, under Section 401 of the Internal Revenue
Code.
Item
9.                      Undertakings.
(a)           The
undersigned registrant hereby undertakes:
(1)           To
file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:
(i)           To
include any prospectus required by section 10(a)(3) of the Securities Act of
1933;
(ii)           To
reflect in the prospectus any facts or events arising after the effective date
of the registration statement (or the most recent post-effective amendment
thereof) which, individually or in the aggregate, represent a fundamental change
in the information set forth in the registration
statement.  Notwithstanding the foregoing, any increase or decrease in
volume of securities offered (if the total dollar value of securities offered
would not exceed that which was registered) and any deviation from the low or
high end of the estimated maximum offering range may be reflected in the form of
prospectus filed with the Commission pursuant to Rule 424(b) if, in the
aggregate, the changes in volume and price represent no more than a 20 % change
in the maximum aggregate offering price set forth in the "Calculation of
Registration Fee" table in the effective registration statement;
II-7
(iii)           To
include any material information with respect to the plan of distribution not
previously disclosed in the registration statement or any material change to
such information in the registration statement;
Provided, however,
That
paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the registration statement
is on Form S-8 and the information required to be included in a post-effective
amendment by those paragraphs is contained in reports filed with or furnished to
the Securities and Exchange Commission by the registrant pursuant to section 13
or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the registration statement.
(2)           That,
for the purpose of determining any liability under the Securities Act of 1933,
each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial
bona fide
offering
thereof.
(3)           To
remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the
offering.
(b)           The
undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to section 13(a) or section 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial
bona fide
offering thereof.
(h)           Insofar
as indemnification for liabilities arising under the Securities Act of 1933 may
be permitted to directors, officers and controlling persons of the registrant
pursuant to the foregoing provisions, or otherwise, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.  In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
