                     NORTHWESTERN PUBLIC SERVICE COMPANY
                               NorthSTAR PLAN

   I.   OBJECTIVE

        The Northwestern Public Service Company NorthSTAR Plan ("Plan")

   is established to accomplish the following objectives:  (1) to

   motivate and reward outstanding performance by Northwestern Public

   Service Company (the "Company") and its employees by providing

   additional compensation to eligible employees who influence the

   profitability of the Company; (2) to compare the Company's performance

   to established annual objectives; (3) to compare individual

   performance to established annual objectives; (4) to focus on

   stockholder and ratepayer interests and (5) to support long-term

   objectives by achieving short-term goals.


   II.  ADMINISTRATION

        The Plan shall be administered by the Company.  The Nominating

   and Compensation Committee ("Committee") of the Company's Board of

   Directors ("Board"), shall have responsibility and authority with

   respect to the Plan, including the following:  (1) approving

   performance measures and the measurement scale used; (2) reviewing

   eligibility for Plan participation; (3) approving the size of the

   performance fund ("Performance Fund"); and (4) reviewing and approving

   awards for all Executive Officers.


   III. ELIGIBILITY FOR PARTICIPATION

        Employees eligible to participate in the Plan are those full-time

   employees who have completed one year of service with the Company and

     35


   who have been selected for participation by Company management.  To be

   eligible for an award, an employee must be employed with the Company

   on December 31st of the year for which the award is based, except as

   hereafter provided in Subsection (b).  

        All Participants will be eligible to participate in the Plan for

   that calendar year unless any of the following circumstances occur:

        (a)  The Participant at any time is discharged from employment

   with the Company for cause ("Cause").  "Cause" shall mean (i) a

   Participant's conviction of any criminal violation involving

   dishonesty, fraud, or breach of trust, or (ii) a Participant's willful

   engagement in any misconduct in the performance of his duty that

   materially injures the Company, or (iii) failure to adequately perform

   his duties; or

        (b)  The Participant's employment with the Company has terminated

   for any reason other than death, permanent disability, or retirement

   on or after the age of sixty- two (62) years or such earlier date as

   the Board, in its discretion, shall designate.  For the purposes of

   this Section, a Participant will be considered to terminate employment

   by reason of "permanent disability" if, in the determination of the

   Board, he is subject to a physical or mental condition which is

   expected to render the Participant unable to perform his usual duties

   or any comparable duties for the Company.


   IV.  DETERMINATION OF PERFORMANCE AWARD AMOUNTS

        (a)  A Performance Award ("Award") shall be awarded under the

   Plan to each Participant based on performance for the applicable

   calendar year which shall be determined by reference to the measures

   of performance for that year. Company management will develop

     36


   schedules for translating results of objectives (i), (ii), and (iii)

   into threshold, target, and maximum achievement levels.  These

   schedules must be approved by the Committee.

        (i)  Company Performance as Measured by Customer Satisfaction

             (25% weight)

             The Company will measure customer satisfaction through the

        use of transaction surveys conducted during the year.

        (ii) Performance vs. Operating Budget (25% Weight)

                The Company will measure the net income of the electric

        and gas operations, as compared to the operating budget.

        (iii)   Company Performance vs. Annual Objective (25% Weight)

             Under this objective, Earnings Per Share, will be the

        primary earnings per share of the Company as it appears in the

        approved budget for the Company.

        (iv) Performance vs. Individual Objectives (25% Weight)

             Each year, Participants will establish several major

        individual and department goals for review and approval by their

        supervisor and by the Manager - Human Resources.  At the end of

        each year, Participants will provide to their supervisor and to

        the Manager - Human Resources an explanation regarding the degree

        to which each goal has been achieved.  The supervisor and the

        Manager - Human Resources will review the Participant's

        explanations and will then recommend the achievement level for

        each Participant to the Chief Executive Officer, who will

        determine the achievement level eligible for an Award.

        (b)  At the end of each calendar year, percentages will be

   computed and totaled for each Participant for each of the Measures of

   Performance.  Each Participant will receive an Award for the

     37


   applicable calendar year equal to a percentage of his base salary on

   December 31st, less any applicable taxes.  Threshold is defined as a

   composite twenty-five percentage level, Target as a composite fifty

   percentage level, and Maximum as a composite one hundred percentage

   level.

        The total amount of all awards made to Participants shall not

   exceed seven percent (7%) of the Company's net after tax income for

   that year.

        (c)  All Executive Officer Awards shall be reviewed, and must be

   approved, by the Committee.  All Awards for other Company employees

   shall be reviewed, and must be approved, by the Chief Executive

   Officer of the Company.

        (d)  Annual base salary adjustments, as appropriate, will

   continue to be made by the Company to individual employees predicated

   on merit, performance, cost-of-living and such other factors as the

   Company normally has considered without regard to Awards awarded under

   the Plan.

        (e)  Awards shall be paid to each Participant in a single sum as

   promptly as practicable after approved.


   V.   PARTICIPANT'S DEATH

        (a)  In the event of the death of the Participant, any unpaid

   Award held for the Participant shall be paid as promptly as

   practicable in a single sum to the Participant's designated

   Beneficiary.

        (b)  In the event the Participant has not designated a

   Beneficiary, or if no designated Beneficiary is living at the date of

   death of the Participant, the unpaid Award shall be paid as promptly

     38


   as practicable in a single sum to the duly appointed executor or

   administrator of the Participant's estate.

        (c)  For purposes of this Section, "Beneficiary" shall mean any

   individual, corporation, partnership, association, trust or

   unincorporated organization designated by a Participant in writing

   filed with the Company as the recipient of the Participant's Award in

   the event of the Participant's death prior to its payment.  Such

   designation may be changed by the Participant at any time in writing

   filed with the Company without the consent of or notice to any

   Beneficiary previously designated.


   VI.  CONTINUITY OF THE PLAN

        Although it is the present intention of the Company to continue

   the Plan in effect for an indefinite period of time, the Board

   reserves the right to terminate the Plan in its entirety as of the end

   of any calendar year or other fiscal year of the Company or to modify

   the Plan as it exists from time to time, provided that no such action

   shall adversely affect any Awards previously awarded under the Plan.


   VII. MISCELLANEOUS PROVISIONS

        (a)  No Award payable under the Plan shall be subject in any

   manner to transfer, assignment, pledge, or hypothecation in any manner

   by operation of law or otherwise, other than by will or by the laws of

   descent and distribution nor be subject to execution, attachment or

   similar process.

        (b)  Neither the Plan nor any action taken hereunder shall be

   construed as giving any Participant any right to be retained in the

   employ of the Company.

     39


        (c)  The Plan shall at all times be entirely unfunded and no

   provision shall at any time be made with respect to segregating assets

   of the Company for payment of any Awards hereunder.  No Participant or

   any other person shall have any interest in any particular assets of

   the Company by reason of the right to receive an Award under the Plan

   and any such Participant or any other person shall have only the

   rights of a general unsecured creditor of the Company with respect to

   any rights under the Plan.

        (d)  Except when otherwise required by the context, any masculine

   terminology in this document shall include the feminine, and any

   singular terminology shall include the plural.

        (e)  This Plan shall be governed by the laws of the State of

   South Dakota.



        IN WITNESS WHEREOF, the Company has executed this revised

   NorthSTAR Plan as of the 4th day of February, 1998.
