Annex A

RESTRICTED STOCK UNIT AWARD AGREEMENT

UNDER THE MDU RESOURCES GROUP, INC.

LONG-TERM PERFORMANCE-BASED INCENTIVE PLAN

MDU Resources Group, Inc. (the “Company”) has granted to you an Award consisting of restricted stock units, subject to the terms and conditions set forth herein and in the Restricted Stock Unit Award Notice (the “Award Notice”). The Award has been granted to you pursuant to the MDU Resources Group, Inc. Long-Term Performance-Based Incentive Plan (the “Plan”). Subject to the terms of the Plan, decisions and interpretations of the Compensation Committee of the Company’s Board of Directors (the “Committee”) are binding, conclusive and final upon any questions arising under the Award Notice, this Restricted Stock Unit Award Agreement (the “Agreement”) or the Plan. Unless otherwise defined herein or in the Award Notice, capitalized terms shall have the meanings assigned to such terms in the Plan.

1.Grant of RSUs. On the Grant Date, you were awarded the number of RSUs set forth in the Award Notice.

2.Vesting of RSUs. The RSUs shall become vested and nonforfeitable in accordance with the Vesting Schedule set forth in the Award Notice. Vesting may be accelerated only as described in the Award Notice.

3.Termination of employment. Except for termination of employment due to death, disability, retirement upon reaching age 55 with 10 Years of Service, or a Change of Control as defined in the Plan, any unvested portion of the Award will be forfeited and/or cancelled on the date you cease to be an employee of the Company or an Affiliate.

4.Settlement of RSU. Each RSU, at the discretion of the Committee, will be settled in Shares as soon as practicable after the Vesting Date but in no event later than 60 days after unvested RSUs become vested RSUs. You shall retain 50% of the net after-tax Shares that are earned under this Award until the earlier of (i) the end of the two-year period commencing on the date any Shares earned under this Award are issued and (ii) your termination of employment. Executives are required to own Shares at designated multiples of their base salary. If you have not achieved an applicable stock ownership requirement, the Company may require you to hold additional net after-tax Shares received under this Award until the requirement is met.

5.Voting Rights. Since RSUs do not represent actual Shares, no voting rights or other rights as a stockholder of the Company arise with respect to the RSUs until Shares have been delivered to you upon settlement of the RSUs.

6.Dividend Equivalents. Dividend Equivalents will be earned with respect to any Shares issued pursuant to the Award. The amount of Dividend Equivalents earned shall be equal to the total dividends declared on a Share for stockholders of record between the Grant Date of this Award and the vesting date of the RSUs, multiplied by the number of Shares issued pursuant to the vesting of the RSUs awarded in the Award Agreement. Any Dividend Equivalents earned shall be paid in cash when the Shares to which they relate are issued or as soon thereafter as practicable, but no later than 60 days after the Shares are issued. No Dividend Equivalents will be issued for unvested or forfeited RSUs.

7.Tax Withholding. Pursuant to Article 14 of the Plan, the Committee has the power and the right to deduct or withhold, or require the Participant to remit to the Company, an amount sufficient to satisfy any federal, state and local taxes (including the Participant's FICA obligations) required by law to be withheld with respect to the Award and Dividend Equivalents. The Committee may condition the delivery of vested Shares upon the Participant's satisfaction of such withholding obligations. The withholding requirement for Shares will be satisfied by the Company withholding Shares having a Fair Market Value equal to federal income tax withholding obligations using an IRS accepted methodology plus additional amounts for state and local tax purposes, as applicable, including payroll taxes, that are applicable to such supplemental taxable income but with rates not to exceed the maximum effective statutory rates, unless the Participant elects, in a manner satisfactory to the Committee,

to remit an amount to satisfy the withholding requirement subject to such restrictions or limitations that the Committee, in its sole discretion, deems appropriate. Such election must be made before, and is irrevocable after, December 15 of the last year in the Vesting Schedule, and cannot be made or revoked while the Participant possesses information that will be material nonpublic information at the time the Shares are issued such that the Participant would be prohibited from trading on the Company’s stock under its Insider Trading Policy.

8.Non-Guarantee of Employment Relationship or Future Awards. Nothing in the Plan, the Award Notice or this Agreement will alter your at-will or other employment status with the Company or an Affiliate, nor be construed as a contract of employment between you and the Company or an Affiliate, or as a contractual right for you to continue in the employ of the Company or an Affiliate for any period of time, or as a limitation of the right of the Company or an Affiliate to discharge you at any time with or without cause or notice and whether or not such discharge results in the forfeiture of any of your RSUs, or as a right to any future Awards.

9.Non-transferability of RSUs. No RSUs granted under the Plan may be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution.

10.Personal Information. You agree the Company and its suppliers or vendors may collect, use and disclose your personal information for the purposes of the implementation, management, administration and termination of the Plan.

11.Amendment. The Committee may amend, alter, modify, suspend or terminate the Award Notice or this Agreement at any time and from time to time, in whole or in part; provided, however, no amendment, alteration, modification, suspension or termination of the Award Notice or Agreement shall adversely affect in any material way the Award Notice or this Agreement, without your written consent, except to the extent such amendment, alteration, modification, suspension or termination is reasonably determined by the Committee in its sole discretion to be necessary to comply with applicable laws, rules, regulations, or is necessary for such approvals by any governmental agencies or national securities exchanges as may be required.

12.Binding Effect. This Agreement shall inure to the benefit of the successors and assigns of the Company and, subject to the restrictions on transfer set forth herein, be binding upon you and your heirs, beneficiaries, executors, legal representatives, successors and assigns.

13.Integrated Agreement. The Award Notice, this Agreement and the Plan constitute the entire understanding and agreement between you and the Company with respect to the subject matter contained herein or therein and supersedes any prior agreements, understandings, restrictions, representations, or warranties between you and the Company with respect to such subject matter other than those as set forth or provided for herein or therein.

14.Ratification of Actions. By accepting the Award or other benefit under the Plan, you and each person claiming under or through you shall be conclusively deemed to have indicated your acceptance and ratification of, and consent to, any action taken under the Plan or the Award by the Company, its Board of Directors, or the Committee.

15.Notices. Any notice hereunder to the Company shall be addressed to its office, 1200 West Century Avenue, Bismarck, North Dakota 58503; Attention: Corporate Secretary, and any notice hereunder to you shall be addressed to you at the address specified on the Award Agreement, subject to the right of either party to designate at any time hereafter in writing some other address.

16.Governing Law. To the extent not preempted by Federal law, the Award Notice and this Agreement shall be governed and construed in accordance with the laws of the State of Delaware, without regard to conflicts of law provisions. In the event any provision of the Award Agreement shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Award Agreement, and the Award Agreement shall be construed and enforced as if the illegal or invalid provision had not been included.

17.Construction. Captions and titles contained in this Agreement are for convenience only and shall not affect the meaning or interpretation of any provision of this Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise.

18.Conformity. This Agreement is intended to conform in all respects with, and is subject to all applicable provisions of, the Plan. Any conflict between the terms of the Award Notice, this Agreement and the Plan shall be resolved in accordance with the terms of the Plan. In the event of any ambiguity in the Award Notice or this Agreement or any matters as to which the Award Notice and this Agreement are silent, the Plan shall govern. Any conflict between the terms of the Award Notice and the Agreement shall be resolved in accordance with the terms of the Agreement.
