MDU RESOURCES GROUP, INC.

EXECUTIVE INCENTIVE COMPENSATION PLAN

____________________________________________________________

I.    ESTABLISHMENT AND PURPOSE

The Executive Incentive Compensation Plan (the “Plan”) was adopted by the Board of Directors of MDU Resources Group, Inc. (“MDUR”) on November 4, 1982 and subsequently amended. Effective January 1, 2012, the Plan was further amended, and the Montana-Dakota Utilities Co. Executive Incentive Compensation Plan, the MDU Construction Services Group, Inc. Executive Incentive Compensation Plan, the Knife River Corporation Executive Incentive Compensation Plan and the WBI Holdings, Inc. Executive Incentive Compensation Plan (collectively, the “Business Unit Plans”) were merged into the Plan. All awards with respect to services performed in 2011 and earlier that were earned and deferred pursuant to any of the Business Unit Plans shall be subject to the terms of the applicable Business Unit Plans in effect at the time the awards were granted. Deferral elections for awards relating to services to be performed during 2012 made pursuant to any of the Business Unit Plans shall be deemed to have been made pursuant to the Plan.

The purpose of the Plan is to provide an incentive for key executives of MDUR, its business segments, divisions and subsidiaries to focus their efforts on the achievement of corporate performance goals. The Plan is designed to reward successful performance as measured against specified performance goals. When performance reaches or exceeds the performance targets, incentive compensation awards, in conjunction with salaries, will provide a level of compensation which recognizes the skills and efforts of the key executives.

II.     DEFINITIONS

Capitalized terms not otherwise defined herein shall have the meanings given them in the Rules and Regulations.

III.    BASIC PLAN CONCEPT

The Plan provides an opportunity to earn annual incentive compensation based on the achievement of specified annual performance goals. A target incentive award for each individual within the Plan is established based on the position level and base salary (“Salary”). The target incentive award represents the amount to be paid, subject to the achievement of the performance goals established each year. Larger incentive awards than target may be authorized when performance exceeds targets; lesser or no amounts may be paid when performance is below target.

It is recognized that during a Plan Year major unforeseen changes in economic and environmental conditions or other significant factors beyond the control of management may substantially affect the ability of the Participants to achieve the specified performance goals. Therefore, in its review of performance the Administrator may modify the performance targets. However, it is contemplated that such target modifications will be necessary only in years of unusually adverse or favorable external conditions.

IV.    ADMINISTRATION

The Plan shall be administered by the Compensation Committee of the Board of Directors of MDUR (the “Administrator”). The Compensation Committee of the Board of Directors of MDUR shall adopt Rules and Regulations for the administration of the Plan. With respect to employees who are not subject to Section 16 of the Securities Exchange Act of 1934, as amended, the Chief Executive Officer of MDUR, with respect to MDUR employees, and

MDUR - 2

the chief executive officer of each business segment, in conjunction with the Chief Executive Officer of MDUR, with respect to the business segment’s employees, shall be the Administrator.

The Administrator shall approve the list of eligible Participants and the target incentive award level for each position within the Plan. The Plan’s performance targets for the year shall be approved by the Administrator no later than 90 days after the beginning of that Plan Year. The Administrator shall have final discretion to determine actual award payment levels, method of payment, and whether or not payments shall be made for any Plan Year.

The Board of Directors of MDUR may, at any time and from time to time, alter, amend, supersede or terminate the Plan in whole or in part, provided that no termination, amendment or modification of the Plan shall adversely affect in any material way an award that has met all requirements for payment without the written consent of the Participant holding such award, unless such termination, modification or amendment is required by applicable law.

V.    ELIGIBILITY

Executives who are determined by the Administrator to have a key role in both the establishment and achievement of their company’s objectives shall be eligible to participate in the Plan.

Nothing in the Plan shall interfere with or limit in any way the right of an employer to terminate any Participant’s employment at any time, for any reason or no reason in its sole discretion, or confer upon any Participant any right to remain employed by the employer. No executive shall have the right to be selected to receive an award under the Plan, or, having been so selected, to be selected to receive a future award.

MDUR - 3

VI.    PLAN PERFORMANCE MEASURES

Performance measures shall be established that consider shareholder and/or customer interests. These measures shall be evaluated annually based on achievement of specified goals.

The performance measures will be determined by the Administrator. These measures may be applied at the MDUR level, the business segment level and/or a division or subsidiary level. The Administrator may assign different performance measures and/or different weights to performance measures for each Participant.

The Administrator may establish threshold, target and/or maximum award levels annually for some or all of the performance measures. The Administrator will retain the right to make all interpretations as to the actual attainment of the desired results and will determine whether any circumstances beyond the control of management need to be considered.

VII.    TARGET INCENTIVE AWARDS

Target incentive awards will be expressed as a percentage of each Participant’s Salary. These percentages shall vary by position and reflect larger reward opportunity for positions having greater effect on the establishment and accomplishment of the corporate objectives. A schedule showing the target awards as a percentage of Salary for eligible positions will be prepared for each Plan Year.

VIII.    INCENTIVE FUND DETERMINATION

The target incentive fund is the sum of the individual target incentive awards for all eligible Participants. Once the incentive targets have been determined by the Administrator, a target incentive fund shall be established and accrued ratably by MDUR and each of its business segments, divisions and/or

MDUR - 4

subsidiaries, as applicable. The incentive fund and accruals may be adjusted during the year.

At the close of each Plan Year, the Chief Executive Officer of MDUR will cause to be prepared an analysis showing performance in relation to each of the performance measures employed. This will be provided to the Administrator for review and comparison to threshold, target and/or maximum, if applicable, performance levels. In addition, any recommendations of the Chief Executive Officer of MDUR or the Administrator will be presented at this time. The Administrator will then determine the amount of the target incentive fund earned.

IX.    INDIVIDUAL AWARD DETERMINATION

Each individual Participant's award will be based upon the level of performance achieved relative to the established performance measures, as determined by a percentage from 0 percent to a maximum of 250 percent, as determined by the Administrator.

X.    PAYMENT OF AWARDS

Except as provided below or as otherwise determined by the Administrator, in order to receive an award under the Plan, the Participant must remain in the employment of the Participant’s employer for the entire Service Year. If a Participant terminates employment with MDUR pursuant to Section 5.01 of MDUR’s Bylaws which provides for mandatory retirement for certain officers on their 65th birthday (or terminates employment with a business segment, division and/or subsidiary of MDUR pursuant to a similar company Bylaw provision) and if the Participant’s 65th birthday occurs during the Service Year, determination of whether the performance measures have been met will be made at the end of the Service Year, and to the extent met, payment of the award will be made to the Participant, prorated. Proration of awards

MDUR - 5

shall be based upon the number of full months elapsed from and including January to and including the month in which the Participant’s 65th birthday occurs. The prorated award shall be paid as soon as practicable in the year following the Service Year, but in all events between January 1 and March 10.

A Participant who transfers between the Participant’s employer at the time the award is granted and MDUR or any of its business segments, divisions or subsidiaries may receive a prorated award at the discretion of the Administrator.

Payments made under the Plan will not be considered part of compensation for pension purposes. Payments will be made in cash as soon as practicable in the year following the Service Year, but in all events between January 1 and March 10.

To the extent approved by the Administrator of the Plan with respect to executives of MDUR, its business segments, divisions or subsidiaries, as applicable, incentive awards may be deferred if the appropriate elections have been executed prior to the beginning of the Service Year. A deferral election will be effective only for the incentive award earned in the Service Year following the Plan Year in which the election is made. Deferral elections may not be changed or revoked after the Service Year begins. Deferred amounts shall be subject to the terms of the Plan and the Rules and Regulations and, to the extent not inconsistent therewith, the deferral election forms pursuant to which the amounts were deferred. Deferred amounts will accrue interest at a rate determined annually by the Compensation Committee of the Board of Directors of MDUR and specified in the Rules and Regulations.

In the event of a "Change in Control" (as defined in the Rules and Regulations) then any award deferred by each Participant shall become immediately payable to the Participant in cash, together with accrued interest thereon to the date of payment. In the event the Participant files suit to collect the

MDUR - 6

Participant's deferred award then all of the court costs, other expenses of litigation, and attorneys' fees shall be paid by MDUR or one of its business segments, divisions or subsidiaries, as applicable, in the event the Participant prevails upon any of the Participant's claims for payment of a deferred award.

XI.    ACCOUNTING RESTATEMENTS

This Section XI shall apply to incentive awards granted to all Participants in the Plan. Notwithstanding anything in the Plan or the Rules and Regulations to the contrary, if MDUR’s audited financial statements are restated, the Compensation Committee of the Board of Directors of MDUR (the “Compensation Committee”) may, in accordance with its Guidelines for Repayment of Incentives Due to Accounting Restatements, take such actions as it deems appropriate (in its sole discretion) with respect to

(a)    unpaid incentive awards under the Plan (including incentive awards relating to completed Plan Years, but with respect to which payments have not yet been made or deferred) ("Outstanding Awards") and

(b)    prior incentive awards that were paid (or deferred) within the three-year period preceding the restatement ("Prior Awards"), provided such Prior Awards were not paid prior to the date the Plan was amended to add this Section XI,

if the calculation of the amounts payable, paid or deferred under such awards are, or would have been, directly impacted by the restatement, including, without limitation, (i) securing (or causing to be secured) repayment of some or all payments made pursuant to (or deferrals relating to) Prior Awards, (ii) making (or causing to be made) additional payments (or crediting additional deferrals), (iii) reducing or otherwise adjusting the amount payable pursuant to Outstanding Awards and/or (iv) causing the forfeiture of Outstanding Awards. The Compensation Committee

MDUR - 7

may, in its sole discretion, take different actions pursuant to this Section XI with respect to different awards, different Participants (or beneficiaries) and/or different classes of awards or Participants (or beneficiaries). The Compensation Committee has no obligation to take any action permitted by this Section XI. The Compensation Committee may consider any factors it chooses in taking (or determining whether to take) any action permitted by this Section XI, including, without limitation, the following:

(A)    The reason for the restatement of the financial statements;

(B)    The amount of time between the initial publication and subsequent restatement of the financial statements; and

(C)    The Participant's current employment status, and the viability of successfully obtaining repayment.

If the Compensation Committee requires repayment of all or part of a Prior Award, the amount of repayment may be based on, among other things, the difference between the amount paid to the individual and the amount that the Compensation Committee determines in its sole discretion should have been paid based on the restated results. The Compensation Committee shall determine whether repayment shall be effected (i) by seeking repayment from the Participant, (ii) by reducing (subject to applicable law and the terms and conditions of the applicable plan, program or arrangement) the amount that would otherwise be provided to the Participant under any compensatory plan, program or arrangement maintained by MDUR or any of its business segments, divisions or subsidiaries, (iii) by withholding payment of future increases in compensation (including the payment of any discretionary bonus amount) or grants of compensatory awards that would otherwise have been made in accordance with otherwise applicable compensation practices of MDUR or its business segments, divisions or subsidiaries, as applicable, or (iv) by any

MDUR - 8

combination of the foregoing. Additionally, by accepting an incentive award under the Plan, Participants acknowledge and agree that the Compensation Committee may take any actions permitted by this Section XI with respect to Outstanding Awards to the extent repayment is to be made pursuant to another plan, program or arrangement maintained by MDUR or any of its business segments, divisions or subsidiaries.
