                  MDU RESOURCES GROUP, INC.
           1997 EXECUTIVE LONG-TERM INCENTIVE PLAN

              PERFORMANCE SHARE AWARD AGREEMENT

     It is understood and agreed that the Award of
Performance Shares evidenced by the Award Agreement to which
this is annexed is subject to the following additional terms
and conditions.

     1.   Nature of Award.  The Target Award represents the
opportunity to receive shares of Company common stock, $1.00
par value ("Shares") and Dividend Equivalents on such
Shares.  The number of Shares that may be earned under this
Award shall be determined pursuant to Section 2 hereof.  The
amount of Dividend Equivalents that may be earned under this
Award shall be determined pursuant to Section 4 hereof.
Except for Dividend Equivalents, which are paid in cash,
Awards will be paid in Shares.

     2.   Determination of Number of Shares Earned.

          The number of Shares earned, if any, for the
Performance Period shall be determined in accordance with
the following formula:

          # of Shares = Payout Percentage X Target Award

The "Payout Percentage" is based on the Company's total
shareholder return ("TSR") relative to that of the Peer
Group listed on Annex B (the "Percentile Rank") for the
Performance Period, determined in accordance with the
following table:

        Percentile Rank                 Payout Percentage
                                       (% of Target Award)
             100th                             200%
              75th                             150%
              50th                             100%
              40th                             10%
         less than 40th                         0%

If the Company achieves a Percentile Ranking between the
40th and 50th percentiles, the Payout Percentage shall be
equal to 10%, plus 9% for each Percentile Rank whole
percentage above the 40th percentile.  If the Company
achieves a Percentile Ranking between the 50th and 100th
percentiles, the Payout Percentage shall be equal to 100%,
plus 2% for each Percentile Rank whole percentage above the
50th percentile.

The Percentile Rank of a given company's TSR is defined as
the percentage of the Peer Group companies' returns falling
at or below the given company's TSR.  The formula for
calculating the Percentile Rank follows:

     Percentile Rank = (n - r + 1)/n x 100

     Where:

     n =  total number of companies in the Peer Group,
          including the Company

     r =  the numeric rank of the company's TSR relative to
          the Peer Group, where the highest return in the
          group is ranked number 1

To illustrate, if the Company's TSR is the third highest in
the Peer Group comprised of 27 companies, its Percentile
Rank would be 93.  The calculation is: (27 - 3 + 1)/27 x 100
= 93.

The Percentile Rank shall be rounded to the nearest whole
percentage.

If the common stock of a company in the Peer Group ceases to
be traded during the Performance Period, the company would
be deleted from the Peer Group.  Percentile Rank would be
calculated without regard to the return of the deleted
company.

Total shareholder return is the percentage change in the
value of an investment in the common stock of a company from
the initial investment made on the last trading day in the
calendar year preceding the beginning of the performance
period through the last trading day in the final year of the
performance period.  It is assumed that dividends are
reinvested in additional shares of common stock at the
frequency paid.

All Performance Shares that are not earned for the
Performance Period shall be forfeited.

     3.   Issuance of Shares. Subject to any restrictions on
distributions of Shares under the Plan, and subject to
Section 6 of this Annex A, the Shares earned under the
Award, if any, shall be issued to the Participant as soon as
practicable following the close of the Performance Period.

     4.   Dividend Equivalents. Dividend Equivalents shall
be earned with respect to any Shares issued to the
Participant pursuant to this Award.  The amount of Dividend
Equivalents earned shall be equal to the total dividends
declared on a Share between the Date of Grant of this Award
and the last day of the Performance Period, multiplied by
the number of Shares issued to the Participant pursuant to
the Award Agreement.  Any Dividend Equivalents earned shall
be paid in cash to the Participant when the Shares to which
they relate are issued or as soon as practicable thereafter.
If the Award is forfeited or if no Shares are issued, no
Dividend Equivalents shall be paid.

     5.   Termination of Employment.

          (a)  If the Participant's employment with the
Company is terminated for any reason other than "Cause" (as
defined below) (1) during the first year of the Performance
Period, all Performance Shares (and related Dividend
Equivalents) shall be forfeited; (2) during the second year
of the Performance Period, determination of the Company's
Percentile Rank for the Performance Period will be made by
the Committee at the end of the Performance Period, and
Shares (and related Dividend Equivalents) earned, if any,
will be paid based on the Payout Percentage, prorated for
the number of full months elapsed from and including the
month in which the Performance Period began to and including
the month in which the termination of employment occurs; and
(3) during the third year of the Performance Period,
determination of the Company's Percentile Rank for the
Performance Period will be made by the Committee at the end
of the Performance Period, and Shares (and related Dividend
Equivalents) earned, if any, will be paid based on the
Payout Percentage without prorating.

          (b)  If the Participant's employment is terminated
for "Cause" (as defined below) during the Performance
Period, all Performance Shares (and related Dividend
Equivalents) shall be forfeited.

          (c)  For purposes of the Award Agreement, the term
"Cause" shall mean the Participant's fraud or dishonesty
that has resulted or is likely to result in material
economic damage to the Company or a Subsidiary, or the
Participant's willful nonfeasance if such nonfeasance is not
cured within ten days of written notice from the Company or
a Subsidiary, as determined in good faith by a vote of at
least two-thirds of the non-employee directors of the
Company at a meeting of the Board at which the Participant
is provided an opportunity to be heard.

     6.   Tax Withholding. Pursuant to Article 16 of the
Plan, the Committee shall have 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.  The Committee may condition the delivery of
Shares upon the Participant's satisfaction of such
withholding obligations.  The Participant may elect to
satisfy all or part of such withholding requirement by
tendering previously-owned Shares or by having the Company
withhold Shares having a Fair Market Value equal to the
minimum statutory withholding that could be imposed on the
transaction (based on minimum statutory withholding rates
for Federal, state, and local tax purposes, as applicable,
including payroll taxes, that are applicable to such
supplemental taxable income).  Such election shall be
irrevocable, made in writing, signed by the Participant, and
shall be subject to any restrictions or limitations that the
Committee, in its sole discretion, deems appropriate.

     7.   Ratification of Actions. By accepting the Award or
other benefit under the Plan, the Participant and each
person claiming under or through him or her shall be
conclusively deemed to have indicated the Participant's
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.

     8.   Notices. Any notice hereunder to the Company shall
be addressed to its office, Schuchart Building, 918 East
Divide Avenue, P.O. Box 5650, Bismarck, North Dakota 58506;
Attention: Corporate Secretary, and any notice hereunder to
the Participant shall be addressed to him or her 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.

     9.   Definitions. Capitalized terms not otherwise
defined herein or in the Award Agreement shall have the
meanings given them in the Plan.

     10.  Governing Law and Severability. To the extent not
preempted by Federal law, the Award Agreement will be
governed by 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.

     11.  No Rights to Continued Employment.  The Award
Agreement is not a contract of employment.  Nothing in the
Plan or in the Award Agreement shall interfere with or limit
in any way the right of the Company or any Subsidiary to
terminate the Participant's employment at any time, for any
reason or no reason, or confer upon the Participant the
right to continue in the employ of the Company or a
Subsidiary.

     a.   Ronald D. Tipton, in exchange for the payment and other
considerations set forth  above, the sufficiency of which is
hereby acknowledged and which is acknowledged to provide good
consideration to Ronald D. Tipton to which he is not entitled
unless he signs this Agreement, on behalf of himself and his
representatives, spouse, agents, heirs and assigns, releases and
discharges Companies and Companies' former, current or future
officers, employees, representatives, agents, fiduciaries,
attorneys, directors, shareholders, insurers, predecessors,
parents, affiliates, benefit plans, successors, heirs, and
assigns from any and all claims, liabilities, causes of action,
damages, losses, demands or obligations of every kind and nature,
whether now known or unknown, suspected or unsuspected, which
Ronald D. Tipton ever had, now has, or hereafter can, shall or
may have for, upon or by reason of any act, transaction,
practice, conduct, matter, cause or thing of any kind whatsoever
relating to or based upon, in whole or in part, any act,
transaction, practice or conduct prior to the date hereof,
including, but not limited to, matters dealing with Ronald D.
Tipton's employment or retirement from employment and/or any

unknowingly).  This Agreement does not eliminate or release any
coverages which Ronald D. Tipton may have under applicable
directors and officers insurance or his right to indemnification
under the terms of the Companies' bylaws for his time in office.
This release and discharge includes, but is not limited to,

     b.  Ronald D. Tipton agrees that he has not and will not
institute any lawsuit or commence any action asserting any
claims, losses, liabilities, demands or obligations released
hereunder.  Nothing in this provision shall be construed,
however, as prohibiting Ronald D. Tipton from filing a charge or
complaint to test the validity under the Older Workers Benefit
Protection Act or the waiver of Ronald D. Tipton's rights under
the federal ADEA.  Nothing contained herein shall be construed to
prohibit Ronald D. Tipton from filing a charge or complaint with
the Equal Employment Opportunity Commission or the North Dakota
Department of Labor or participating in investigations by those
entities.  However, except for testing the validity of the waiver
noted above, Ronald D. Tipton acknowledges that the release he

Dakota Department of Labor filed court action.  This release does
not extend to rights, remedies, claims or causes of action
arising out of acts governed by Paragraph 5.a., above, occurring
after the effective date of this Agreement and expiration of the
revocation period.

     This Agreement does not apply to, or otherwise impair, any
vested right Ronald D. Tipton has under a presently existing
employee pension or benefit plan or any other claim that may not
be waived by law.

     6.   Known or Unknown Claims.  Ronald D. Tipton understands
and expressly agrees that this Agreement extends to all claims of
every nature and kind, known or unknown, suspected or
unsuspected, past, present, or future, arising from or
attributable to any conduct of the Companies and their
successors, subsidiaries, and affiliates, and all their
employees, owners, shareholders, agents, officers, directors,
predecessors, assigns, agents, representatives, and attorneys,
whether known by Ronald D. Tipton or whether or not Ronald D.
Tipton believes he may have any claims, and that any and all
rights granted to Ronald D. Tipton under N.D.C.C. Section 9-13-02
or any analogous state law or federal law or regulations, are
hereby expressly WAIVED, if applicable.

     7.   No Admission.  Neither this Agreement nor any action or
acts taken in connection with this Agreement or pursuant to it
will constitute an admission by Ronald D. Tipton or by Companies
of any violation of law, nor will it constitute or be construed
as an admission of any wrongdoing whatsoever.

     8.   Nondisclosure of Proprietary and Trade Secret Business
Information.  Ronald D. Tipton agrees to retain in strict
confidence and not to use in any way and not to disclose to any
persons any non-public, confidential, proprietary, or trade
secret information of Companies as described in the North Dakota
Uniform Trade Secret Act.  Ronald D. Tipton further acknowledges
that he has returned to Companies all documents and information
encompassing non-public, confidential, proprietary, or trade
secret information of the Companies.

     9.   No Disparagement.  The parties agree not to make any
disparaging or false statements about each other.

     10.  Change of Control Employment Agreement.  Ronald D.
Tipton and MDU Resources Group Inc. are parties to a Change of
Control Employment Agreement dated November 1, 1998.  Ronald D.
Tipton acknowledges that no "Change of Control" has occurred, as
that term is defined in that agreement and that agreement is
hereby terminated.

     11.  Agreement Regarding No Right to Future Employment.
Ronald D. Tipton agrees that he will not at any time in the
future bring a claim against Companies for any failure to offer
him future employment or failure to accept from him an
application for future employment with Companies.

     12.  Further Documents.  Each party agrees to execute or
cause their counsel to execute any additional documents and take
any further action which may reasonably be required in order to
consummate this Agreement or otherwise fulfill the obligations of
the parties thereunder.

     13.  Choice of Law.  This Agreement shall be construed and
enforced in accordance with the laws of the State of North
Dakota.

     14.  Attorneys' Fees.  Should any action be brought by any
party to this Agreement to enforce any provision thereof, the
prevailing party shall be entitled to recover, in addition to any
other relief, reasonable attorneys' fees and costs and expenses
of litigation or arbitration.  This provision shall not apply to
charges or complaints filed by Ronald D. Tipton to test the
validity under the Older Workers Benefit Protection Act or the
waiver of Ronald D. Tipton's rights under the ADEA.

     15.  Integration.  This Agreement constitutes an integration
of the entire understanding and agreement of the parties with
respect to the matters referred to in this Agreement.  Any
representation, warranty, promise or condition, whether written
or oral, between the parties with respect to the matters referred
to in this Agreement which is not specifically incorporated in
this Agreement shall not be binding upon any of the parties
hereto and the parties acknowledge that they have not relied, in
entering into this Agreement, upon any representations,
warranties, promises or conditions not specifically set forth in
this Agreement.  No prior or contemporaneous oral or written
understanding, covenant, or agreement between the parties, with
respect to the matters referred to in this Agreement, shall
survive the execution of this Agreement.  This Agreement may be
modified only by a written agreement executed by both parties
hereto.

     16.  Binding Agreement.  The parties understand and
expressly agree that this Agreement shall bind the heirs,
subsidiaries, affiliates, successors, and assigns of the
Companies and Ronald D. Tipton.

     17.  Construction.  The language of this Agreement shall be
construed as to its fair meaning and not strictly for or against
either party.  If any part of this Agreement is construed to be a
violation of law, such part shall be modified to achieve the
objective of the parties to the fullest extent permitted and the
balance of this Agreement shall remain in full force and effect.

     18.  Counterparts.  This Agreement may be executed in
counterparts and when each party has signed and delivered at
least one such counterpart, each counterpart shall be deemed an
original and all counterparts taken together shall constitute one
and the same Agreement, which shall be binding and effective as
to all parties.

     19.  Headings.  Headings in this Agreement are for
convenience of reference only and are not a part of the substance
hereof.

     20.  Time for Acceptance and Revocation.  Ronald D. Tipton
acknowledges that he has been advised in writing by Companies to
consult with an attorney prior to signing it.  Ronald D. Tipton
may have up to twenty-one (21) days from the date this Agreement
is presented to Ronald D. Tipton to accept the terms of this
Agreement, although Ronald D. Tipton may accept it at any time
within those twenty-one (21) days.  Ronald D. Tipton agrees that
any changes to this Agreement, whether material or not, will not
restart the period for acceptance.  After acceptance, Ronald D.
Tipton will still have an additional seven (7) days in which to
revoke his acceptance as it relates to federal age discrimination
claims and reinstate any potential claims he might have under the
ADEA.  To so revoke, Ronald D. Tipton must send the Companies a
written statement of revocation.  To be effective, the revocation
must be in writing and hand-delivered or mailed to the Companies
addressed as follows:  MDU Resources Group, Inc., c/o Chief
Executive Officer, P.O. Box 5650, Bismarck, ND  58506-5650,
within the seven (7) day period.  If mailed, the revocation must
be postmarked within the seven (7) day period.

     This Agreement will not be effective and no payment will be
made hereunder until the revocation period has expired.  If
Ronald D. Tipton exercises his option to revoke his ADEA waiver,
the entire Agreement is voidable at the Companies' option within
seven (7) days and neither Ronald D. Tipton nor the Companies
shall have any further rights or obligations pursuant to this
Agreement.

     21.  Severability.  Should any court with jurisdiction
determine that any provision of this Agreement is invalid, void
or unenforceable; the remaining provisions shall remain in full
force and effect.
