Annual Incentive Awards
-----------------------

On February 14, 2007, the Compensation Committee (the "Committee") of the Board
of Directors (the "Board") of MDU Resources Group, Inc. (the "Company")
established 2007 annual award opportunities for its executive officers who will
be named executive officers ("NEOs") in the proxy statement for the 2007 Annual
Meeting of Stockholders. The Board approved the award opportunities at its
meeting on February 15, 2007. Filed herewith as Exhibit 10.1 and incorporated
herein by reference is the 2007 NEO Annual Award Opportunity Chart.

Executive officers may receive annual cash incentive awards based upon
achievement of annual performance measures with a threshold, target and maximum
level. A target incentive award is established based upon the position level and
actual base salary. Actual payment may range from zero to 200% of the target
based upon achievement of corporate goals.

Participants who retire, die or become disabled during the year remain eligible
to receive an award. Subject to the Committee's discretion, participants who
terminate employment for other reasons are not eligible for an award. The
Committee has full discretion to determine the extent to which goals have been
achieved, the payment level, whether any final payment will be made and whether
to adjust awards downward.

Mr. Hildestad's and Mr. Raile's 2007 awards were made pursuant to
the Long-Term Performance-Based Incentive Plan. The performance goals for 2007
for Mr. Hildestad and Mr. Raile are (i) budgeted earnings per share achieved
(weighted 50%) and (ii) budgeted return on invested capital achieved (weighted
50%) with respect to the Company.

Mr. Harp's 2007 award was made pursuant to the MDU Construction Servces Group,
Inc. Executive Incentive Compensation Plan, based upon (i) budgeted earnings per
allocated share achieved (weighted 50%) and (ii) budgeted return on invested
capital achieved (weighted 50%) for MDU Construction Services Group, Inc.

Mr. Schneider's 2007 award was made pursuant to the Knife River Corporation
Executive Incentive Compensation Plan, based upon (i) budgeted earnings per
allocated share achieved (weighted 50%) and (ii) budgeted return on invested
capital achieved (weighted 50%) for Knife River Corporation.

Mr. Castleberry's 2007 award was made pursuant to MDU Resources Group, Inc.
Executive Incentive Compensation Plan based upon (i) budgeted earnings per share
achieved (weighted 50%) and (ii) budgeted return on invested capital achieved
(weighted 50%).

Achievement of budgeted levels of earnings per allocated share and return on
invested capital would result in a potential award of 100% of the target amount.
Achievement of less than 85% would result in no payment, while achievement of
115% would result in a payment of 200% of the target amount.

Annual incentive award payments above the targeted incentive amounts are
limited. The limitation restricts total payments at the major business units to
ensure that only a portion of incremental earnings above budget will be paid to
annual incentive award recipients.

                                       2


Long-Term Incentive Awards
--------------------------

On February 14, 2007, the Committee also granted performance shares to the NEOs
for the 2007-2009 performance period. The Board approved the performance share
grants at its meeting on February 15, 2007. Filed herewith as Exhibit 10.2 and
incorporated herein by reference is the 2007 NEO Performance Share Award Chart.
Target grants were based on a percent of base salary.

The performance goal for the 2007-2009 performance period is the Company's total
stockholder return in comparison to the total stockholder returns of companies
in the performance graph peer group. The payout percentage will range from 0% to
200% of the target grant. Performance shares that are earned will be paid in
Company stock; dividend equivalents will be paid in cash.

The companies in the performance graph peer group have been changed for 2007.
The new group is included as Annex B to the Form of Performance Share Award
Agreement, which is filed as Exhibit 10.3.
