      INSTRUMENT

      AMENDMENT
TO THE

      MDU
RESOURCES GROUP, INC.

      401(k)
RETIREMENT PLAN

      

       

      The MDU Resources
Group, Inc. 401(k) Retirement Plan, as amended and restated December 1, 2006
(the “Plan”), is hereby further amended, effective as of
January 1, 2007, unless otherwise indicated, as follows:

       

      
        	
                 
      

              	
                1.

              	
                By adding the
      following new sentence at the end of Section 3.1(b) of the
      Plan:

              

      

       

      An Employer may
withhold a Participant’s Savings Contributions from any portion of the
Participant’s taxable income (without regard to whether such taxable income
constitutes “Compensation” under the Plan) so long as the applicable deferral
limits set forth in Section 3.1(a) above are not exceeded.

       

      Explanation:  This change
adds an administrative rule of convenience designed to prevent operational
errors if participant deferrals are inadvertently withheld from a different
compensation source.

       

       

      
        	
                 
      

              	
                2.

              	
                By adding the
      following at the end of Section 4.7 of the
Plan:

              

      

       

      With respect to any
portion of a distribution from the Plan on behalf of a deceased Participant made
on or after January 1, 2007, if a direct trustee-to-trustee transfer is made to
an individual retirement plan described in Section 408(a) or (b) of the Code (an
“IRA”), which IRA is established for the purpose of receiving the distribution
on behalf of an individual who is a designated beneficiary (as defined by
Section 401(a)(9)(E) of the Code) of the Participant and who is not the
surviving spouse of the Participant, then the transfer shall be treated as an
eligible rollover distribution for purposes of this Plan and Section 402(c) of
the Code.  For purposes of this subsection, the IRA of the non-spouse
beneficiary is treated as an inherited IRA within the meaning of Section
408(d)(3)(C) of the Code. The Plan may make a direct rollover to an IRA on
behalf of a trust where the trust is the designated beneficiary of a
Participant, provided (1) the beneficiaries of the trust meet the requirements
of a designated beneficiary described above; (2) the IRA is established in
accordance with Internal Revenue Service guidance, with the trust identified as
the beneficiary; and (3) the trust meets the requirements set forth in Treasury
Regulation Section 1.401(a)(9)-4, Q&A-5. The rules of this Section
shall

       

      
        
           

        

        
          1

          
            

          

        

        
           

        

      

       

      be interpreted
consistent with regulations or other guidance prescribed by the Internal Revenue
Service under Section 402(c)(11) of the Code.

       

       

      Explanation:  This change
allows designated (non-spouse) beneficiaries to roll over distributions of
deceased participants’ accounts as permitted by the recent Pension Protection
Act.

       

       

      
        	
                 
      

              	
                3.

              	
                By
      substituting the following for Section 4.8(b) of the Plan in its
      entirety:

              

      

       

       

      (b)           Each
loan must be evidenced by a promissory note prepared in a form approved by the
Committee and shall bear interest at a commercially reasonable rate as
determined by the Committee; provided however, that the applicable interest rate
shall not exceed six percent (6%) during any period that the Participant
receiving the loan is on military leave, in accordance with the Servicemembers
Civil Relief Act. The repayment of any loan must be made in at least quarterly
installments of principal and interest; provided, however, that this quarterly
amortization requirement shall not apply while a Participant is on a leave of
absence (for a period, not longer than one year), if the following conditions
are met:  (i) the Participant is on leave either without pay from the
Employer, or at a rate of pay (after income and employment tax withholding) that
is less than the amount of the installment payments required under the terms of
the loan; (ii) the loan must be repaid by the latest date permitted under
Section 4.8(c), below, and (iii) the installments due after the leave of absence
ends (or if earlier, upon the expiration of the first year of the leave of
absence) must not be less than those required under the terms of the original
loan.

       

       

      Explanation:  This change
adds language to the plan to (1) extend the loan repayment rights of employees
during a leave of absence, including seasonal employee layoffs, and (2) to
clarify that Participants on a qualified military leave shall not be charged
greater than 6% interest.

       

       

      
        	
                 
      

              	
                4.

              	
                By adding the
      following after the first sentence following Section 4.8(c) of the
      Plan:

              

      

       

       

      If a Participant’s
employment is involuntarily terminated in connection with the sale, outsourcing
or other divestiture of an Employer, then the Committee may establish uniform
rules pursuant to which a Participant may elect a rollover of his or her
outstanding loan to an eligible retirement plan.

       

      Explanation:  This change
adds language to the plan to allow the rollover of loan notes, specifically,
Colorado Energy Management, LLC.

       

      
         

        
          	
                   
      

                	
                  5.

                	
                        
                    Effective as
      of July 10, 2007, by substituting the following for the “Colorado Energy
      Management” provision in Schedule A of the
    Plan:

                Colorado
      Energy Management, Inc. (“CEM”) shall make a matching contribution equal
      to one hundred percent (100%) of each CEM employee’s participating savings
      contribution, up to the maximum savings contribution of five percent (5%)
      of compensation for each pay period; provided, however, effective as of
      July 10, 2007, CEM shall no longer be a Participating Affiliate under the
      terms of the Plan and correspondingly shall not make a matching
      contribution for any pay period beginning on or after July 10,
      2007.

              

      

       

       

      Effective May 15,
2004 and as amended July 10, 2007.

       

       

      Explanation:  This change
provides that effective July 10, 2007, Colorado Energy Management shall no
longer be a participating affiliate in the plan and provides that no further
matching contributions will be made on behalf of employees of Colorado Energy
Management, effective July 10, 2007.

amendment to be duly executed by a member of the MDU Resources Group, Inc.
