              1.

            	
              Introduction.  Effective
      January 1, 2007, Young Contractors, Inc., now known as Knife River
      Corporation-South (“KRC-South”), effective March 1, 2007, a Participating
      Affiliate in the Plan, established the profit sharing feature described in
      this Supplement.  The profit sharing feature, effective as of
      January 1, 2007, is in addition to the Matching Contributions provided by
      KRC-South pursuant to the Plan.

            

    

    

    
      	
               
      

            	
              2.

            	
              Eligibility to Share
      in Profit Sharing Contribution.  In order to share in the
      allocation of any profit sharing contribution made by KRC-South pursuant
      to Paragraph 3 below for a given Plan Year, Participants employed by
      KRC-South must complete 1,000 Hours of Service in that Plan Year and be an
      Active Employee of KRC-South on the last day of the Plan
      Year.  However, any Eligible Employee who transfers to Knife
      River Corporation or any of its operating companies during the Plan Year
      and is employed by that company on the last day of the Plan Year will be
      eligible to receive a pro-rated profit sharing contribution for the
      portion of the Plan Year during which the Participant was employed by
      KRC-South so long as the Eligible Employee has completed 1,000 Hours of
      Service cumulatively during the Plan Year.  Participants who
      meet the preceding requirement are referred to herein as “Supplement D-11
      Participants.”

            

    

    

    
      	
               
      

            	
              For purposes
      of this Supplement, an “Active Employee” means an employee who is still on
      the payroll or has been temporarily laid off or who terminated employment
      due to Disability, Death, or Retirement on or after Normal Retirement Date
      during such Plan Year, but does not mean an employee whose employment
      otherwise has terminated effective on or before December 31 of that
      Plan Year.

              3.

            	
              Amount of Profit
      Sharing Contributions, Allocation.  For each Plan Year,
      the Board of Directors of KRC-South, in its discretion, shall determine
      the amount (if any) of profit sharing contributions to be made to the Plan
      based upon the profitability of KRC-South.  The amount of any
      such contribution for a Plan Year shall be allocated to Supplement D-11
      Participants, based upon their Compensation, excluding bonuses, received
      while employed by KRC-South for that Plan
Year.

            

    

    

    
      	
               
      

            	
              4.

            	
              Vesting.  Notwithstanding
      anything in Section 4.2 to the contrary, Supplement D-11 Participants
      shall be vested in their Profit Sharing Accounts only upon completing
      three (3) Years of Vesting Service as defined
  below.

            

    

    

    A “Year of Vesting
Service” means a Plan Year in which the Supplement D-11 Participant completes at
least 1,000 Hours of Service.  In addition, service with KRC-South,
the Company and all Affiliates that occurred prior to the effective date of
Supplement D-11 shall be recognized for purposes of this Paragraph, applying
these rules as if KRC-South (and its affiliates at that time) were Affiliates
under the Plan. Notwithstanding the foregoing, a Participant shall be fully
vested in his or her Profit Sharing Account upon Death, Disability, or attaining
age 65.

      Terms.  Terms used in this Supplement D-11 shall, unless
      defined in this Supplement D-11 or elsewhere noted, have the meanings
      given to those terms in the Plan.

            

    

    

    
      	
               
      

            	
              6.

            	
              Inconsistencies with
      the Plan.  The terms of this Supplement D-11 are a part
      of the Plan and supersede the provisions of the Plan to the extent
      necessary to eliminate inconsistencies between the Plan and the Supplement
      D-11.

            

    

    

    Explanation: This amends
Supplement D-11 of the Plan to reflect the name change to Knife River
Corporation-South from Young Contractors, Inc., effective March 1,
2007.

    

     

    2.  Effective April 1,
2007, the MDU Resources Group, Inc. 401(k) Retirement Plan (as amended and
