ITEM 5.02  DEPARTURE OF DIRECTORS OR PRINCIPAL OFFICERS; ELECTION OF DIRECTORS;
           APPOINTMENT OF PRINCIPAL OFFICERS

     On November 11, 2004, the Board of Directors of MDU Resources Group, Inc.
(the "Company") named Bruce T. Imsdahl, age 56, who has been the President of
Montana-Dakota Utilities Co. and Great Plains Natural Gas Co., both of which are
utility divisions of the Company, to the additional position of Chief Executive
Officer for both utility divisions.

     Mr. Imsdahl began his career with the Company in 1970. Through the years,
he advanced through various positions in power production at a number of the
Company's generating stations and in the corporate office before being named
Vice President - Power Supply of the utility operations in 1989. In 1991, he
assumed responsibility for natural gas supply as well, becoming Vice President -
Energy Supply. He was named Executive Vice President of the utility operations
in early 2003 and was named President later that year.

     Consistent with its arrangements with other Company executives, in May 2004
the Company entered into a Change of Control Employment Agreement with Mr.
Imsdahl that provides certain protections to its executives in the event there
is a change of control of the Company. Specifically, the agreement provides for
a three-year employment period from the date of the change of control, during
which the executive is entitled to receive specified salary and bonus payments
and to participate in various benefit plans. The agreement also provides for
specified severance payments and benefits in the event the executive's
employment is terminated during the employment period (or, if connected to the
change in control, prior thereto) in certain circumstances. For further
information on the terms of these agreements with Mr. Ismdahl and other Company
executives, reference is made to the information under the heading "Change of
Control and Severance Agreements" on page 17 of the Company's March 12, 2004
proxy statement and to Mr. Imsdahl's agreement filed as Exhibit 10(c) to the
Company's Quarterly Report on Form 10-Q for the Quarter Ended June 30, 2004.
