Knife River Corporation (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 Knife River Corporation 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.

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 service. Except for termination of service due to death, Disability, or a Change in Control, any unvested portion of the Award will be forfeited and/or cancelled on the date you cease to provide services to the Company.

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. Directors are required to own Shares at a designated multiple of their annual cash base retainer. If you have not achieved the applicable stock ownership requirement, you are required to hold the net after-tax Shares received under this Award until the requirement is met.

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

8.Non-Guarantee of Employment or Service Relationship or Future Awards. Nothing in the Plan, the Award Notice or this Agreement will be construed as a contractual right for you to continue to provide services to or become employed by the Company.
