     (a)   designating  the  Participants  to  whom  Options  are
     granted under the Plan;

     (b)   authorizing the Trustee to grant Options,  determining
     the  time(s) when Options are granted and fixing the  number
     of  shares  of  Common Stock underlying each Option  granted
     hereunder;

All decisions made by the Committee pursuant to the provisions of
the Plan shall be final and binding on all persons, including the
Companies, the Trustee, and the Plan's Participants.

The  Committee  may also revise or adjust the vesting  provisions
(except  that  the Committee may not extend vesting  beyond  nine
years), goals and their levels applicable to a Performance Cycle,
at  any  time  to  take  into account, among  other  things,  new
Participants, promotions, transfers, terminations, changes in law
and  accounting and tax rules and to make such adjustments as the
Committee   deems  necessary  or  appropriate  to   reflect   the
Companies' performances or the impact of extraordinary or unusual
items, events, or circumstances or in order to avoid windfalls or
hardships.

The  Company and/or the Committee may consult with legal counsel,
who may be counsel for the Company or other counsel, with respect
to  its  obligations and duties hereunder or with respect to  any

IV.  GENERAL PLAN DESCRIPTION

     A.   Overview
     The  Plan  provides  for  each Participant  to  (a)  receive
     grant(s) of Stock Options, (b) have the opportunity to  earn
     dividend  equivalents,  and  (c)  have  the  opportunity  to
     achieve  accelerated  vesting of Stock Options  and  receive
     additional   grants  of  Stock  Options   based   upon   the
     achievement  of  Goals established by the Committee  over  a
     designated Performance Cycle.

     B.   Eligibility
     On or after the Effective Date, subject to the provisions of
     the  Plan,  the Committee shall, from time to  time,  select
     Participants  from Eligible Employees and arrange  with  the
     Trustee  to  grant  them  Stock Options.   At  the  time  of
     selection,  the  Committee  shall  specify  the  terms   and
     conditions  of  the  new  Participant's  initial  grant   of
     Options.

     C.   Authorization
     The  total  number  of shares of Common Stock  as  to  which
     Options may be granted may not exceed 800,000 shares; if any
     unexercised  options lapse or terminate for any reason,  the
     shares underlying the Options may be made subject to Options
     granted  to  other  Participants.   In  the  event  of   the
     declaration  of a Common Stock dividend and/or Common  Stock
     split,   reclassification  or  analogous   change   in   the
     capitalization or any distributions (other than regular cash
     dividends)  to holders of record between the date  of  grant
     and  the  date  of  exercise of an  Option,  an  appropriate
     adjustment shall be made to the total number of shares as to
     which  Options  may  be  granted, to the  number  of  shares
     subject to Options, and to the exercise price.

     Shares  of  Common Stock, delivered under this Plan  may  be
     authorized but unissued shares of Common Stock, or shares of
     Common  Stock purchased on the open market and held  by  the
     Trustee,  or  shares  of  Common Stock  from  the  1983  Key
     Employees' Stock Option Plan.

     D.   Stock Options and Dividend Equivalents
          (1)  Grants
          Each  Participant shall receive a grant of  Options  on
          the   date  she  or  he  becomes  a  Participant.   The
          Committee shall determine the size of the grant to each
          Participant  and  authorize the  Trustee  to  make  the
          grant.   Participants may receive subsequent grants  of
          Options  from the Trustee when and as directed  by  the
          Committee.

          (2)  Exercise Price and Term
          The exercise price for an Option granted under the Plan
          is  the Fair Market Value of the Company's Common Stock
          on  the  date  of  the Option grant. An Option  granted
          shall  generally  have a term of ten  years  commencing
          from  the  date of grant, subject to the provisions  of
          Sections V and VI and to the general discretion of  the
          Committee set forth in Section III.

          (3)  Vesting and Accelerated Vesting Provisions
          No  Option  may  be  exercised before  it  has  vested.
          Generally  Option grants have a vesting period  (before
          accelerated  vesting)  of nine  years  subject  to  the
          provisions  of Section VI and to the general discretion
          of the Committee set forth in Section III.  The vesting
          period  for  all or a portion of Options granted  to  a
          Participant may be accelerated by the Committee subject
          to the achievement of Goals for a Performance Cycle.

          (4)  Performance Cycle and Goals
          The  Committee shall fix the starting and ending  dates
          of  each Performance Cycle.  The minimum term shall  be
          six  months; the maximum term shall be nine  years.   A
          Performance  Cycle  will be the  time  period  used  in
          assessing  the performance of each of the Companies  in
          comparison  to  the separate Goals established  by  the
          Committee  for  each  of  the  Companies.   Performance
          Cycles and Goals may vary for each of the Companies.

          (5)  Subsequent Grants; Accelerated Vesting
          Additional grants of Options may be made by the Trustee
          at  the  direction of the Committee to Participants  at
          any time.

          In particular, but not by way of limitation, additional
          grants  of Options may be made to Participants  at  the
          beginning  of  a new Performance Cycle based  upon  the
          appropriate Companies' achievement of Performance Goals
          and  the  results of accelerated vesting of  all  or  a
          portion  of previous grants.  The Committee  will  have
          the   authority to determine the size and terms of  any
          new Option grant for each Participant.

          (6)  Dividend Equivalents
          At  the beginning of each Performance Cycle, a Dividend
          Account  (the "Dividend Account") shall be  established
          for each Participant.  If a dividend is declared by the
          Board  on the Common Stock of the Company an equivalent
          amount shall be accrued in the Dividend Account of each
          Participant  for each share of Common Stock  underlying
          all  unvested Options held by the Participant.  At  the
          end of each Performance Cycle the Committee in its sole
          discretion may award an amount between 0% and 150% of a
          Participant's  Dividend Account based  on  whether  the
          Goals  established  for  that  Performance  Cycle  were
          achieved.    Any  earned  portion  of  a  Participant's
          Dividend Account is paid in cash to that Participant at
          the  end  of each Performance Cycle at a date and  time
          determined  by  the  Committee.   Any  portion   of   a
          Participant's  Dividend  Account  not  awarded  to  the
          Participant  by  the Committee is forfeited.   However,
          shares  of  Common  Stock underlying  unvested  Options
          retain a dividend equivalent and a Participant can earn
          the  value  of these dividend equivalents in subsequent
          Performance Cycles.

          (7)  Exercise of Options
          As provided in paragraph (3) of this section, generally
          all  Options  granted to a Participant under  the  Plan
          shall  vest  on the ninth anniversary of  the  date  of
          grant; provided, however, that if and to the extent the
          vesting  of an Option is accelerated at the  end  of  a
          Performance   Cycle,  the  Option  may  thereafter   be
          exercised to the extent that the Option has vested. Any
          vested  Option may be exercised from time  to  time  in
          part   or  as  a  whole,  at  the  discretion  of   the
          Participant, from the date of vesting until termination
          of the Option; no Option shall be exercisable after its
          expiration  date;  subject  in  either  case   to   the
          provisions  set forth in Section V and to  the  general
          discretion of the Committee set forth in Section III.

          Options  may be exercised by giving written  notice  of
          exercise to the Trustee specifying the number of shares
          to  be  purchased.  The notice shall be accompanied  by
          the  exercise price.  Payment may also be made in  part
          or  in full by tendering shares of Common Stock already
          owned  by  the Participant, based upon the Fair  Market
          Value  of  the Common Stock on the date the  Option  is
          exercised,  or through share withholding.  Participants
          may  also simultaneously exercise Options and sell  the
          shares  of  Common Stock thereby acquired and  use  the
          proceeds  from  the sale as payment  for  the  purchase
          price  of the shares.  Such transactions, to the extent
          required, shall be effected in accordance with  Section
          16 of the Exchange Act and the rules thereunder.

          (8)  Nonassignability of Options
          Options  granted  may not be assigned, transferred,  or
          pledged  by the Participant other than by will  or  the
          laws  of  descent  and distribution or  pursuant  to  a
          qualified  domestic relations order as defined  by  the
          Internal  Revenue  Code  or Title  1  of  the  Employee
          Retirement   Income   Security  Act,   or   the   rules
          thereunder.

V.   Termination of Service

     A.    Upon any Termination of Service, unvested Options  and
     any  amounts  accrued  in a Participant's  Dividend  Account
     shall  be  forfeited unless the Committee decides  otherwise
     pursuant to Section III.

     B.   Death
     If  the  Participant  dies while still  employed,  then  any
     vested   Options,  to  the  extent  that   they   are   then
     exercisable, may be fully exercised at any time  within  one
     (1)  year  (even  if this extends the term of  the  Options)
     after  the  date of the Participant's death  by  the  person
     designated  in the Participant's last will and testament  or
     by the personal representative of the Participant's estate.

     C.   Disability
     If  the  Participant  suffers Disability,  then  any  vested
     Options,  to the extent that they are then exercisable,  may
     be fully exercised by the Participant at any time within one
     (1)  year  (even if this extends the terms of  the  Options)
     after  the  date of Disability or by a person  qualified  or
     authorized to act on behalf of the Participant.

     D.   Cause
     If  a Participant's Termination of Service is for Cause, the
     right  to  exercise any vested Option shall  terminate  with
     such  termination  of  employment.  For  this  purpose,  the
     determination of the Committee as to whether employment  was
     terminated for Cause shall be final.

     E.   Other Termination of Service
     In the event of the Participant's Termination of Service for
     reasons  other  than Death, Disability,  or  Cause,  to  the
     extent  that  any  vested Options are then exercisable,  the
     Participant  shall be entitled to exercise the  Options  for
     the  three  (3)  month period following such Termination  of
     service (even if this extends the term of the Options).

VI.  Change of Control

Upon  a  Change of Control of the Company, all Options previously
granted  under  the  Plan  shall become  immediately  vested  and
available for exercise.  The value of the amounts accrued in  the
Participant's Dividend Account shall be paid in full at  100%  of
the amount thereof to the Participant in cash upon the Change  of
Control.

VII. Miscellaneous Provisions

     property  or assets of the Company, nor shall  they  be
     beneficiaries  of,  or  have  any  rights,  claims,  or
     interests in any specified assets of the Company.   Any
     and  all  of  the Company's assets shall be and  remain

     B.   No Contract of Employment
     Nothing   contained  in  this  Plan  nor  any   related
     Agreement nor any action taken in the administration of
     the Plan shall be construed as a contract of employment
     or  as giving a Participant any right to be retained in
     the service of the Company.

     C.   Withholding Taxes
     No  later than the date on which a Participant receives
     Common  Stock  with respect to any Option exercised  or
     cash with respect to Dividend Equivalents awarded under

     Company   or   its   delegate  or   make   arrangements
     satisfactory  to the Company regarding the  payment  of
     any  federal, state, or local taxes required by law  to
     be  withheld  with  respect to any such  amounts.   The
     Participant  may  also make payment  (i)  by  tendering
     shares  of  the  Common  Stock  already  owned  by  the
     Participant,  based  on the fair market  value  of  the
     Common  Stock on the date the tax is owed  or  (ii)  by
     having  such  amounts withheld from the shares  of  the
     Common  Stock  otherwise distributable to him/her  upon

     of  the  combined voting power of all classes of voting
     stock of the Company.

     E.   Severability

     related   Agreement   is   held   invalid,   void    or
     unenforceable,  the  same  shall  not  affect,  in  any
     respect whatsoever, the validity of any other provision
     of the Plan or any related Agreement.

     F.   Inurement of Rights and Obligations

     Participants  and their beneficiaries  consistent  with
     the terms of the Plan.

     regulations,  or other applicable laws and regulations;
     provided,  that  no  modification  to  the  Plan  shall
     increase the number of shares available under the  Plan
     by more than 10 percent without approval of the holders
     of  the  Common  Stock, except as  otherwise  permitted
     under Section IV.C; and provided further, that any such
     amendment,   suspension,   or   termination   must   be
     prospective in that it may not deprive Participants  of
     any Options or rights previously granted under the Plan
     whether   vested  or  not,  without  consent   of   the
     Participant, except if required by statute or rules  or
     regulations promulgated thereunder.

     H.   Restrictions
     Shares   of   Common  Stock  acquired  by  Participants
     pursuant  to the exercise of Options granted under  the
     Plan   shall   be  subject  to  such  restrictions   on
     transferability  and disposition  as  are  required  by
     federal  and  state security laws and such Participants
     shall  not sell or transfer any shares acquired  except
     in accordance with such laws.

     I.   Legal and Other Requirements
     The obligation of the Company to cause Common Stock  to
     be  available  under the Plan shall be subject  to  all
     applicable  laws,  regulations,  rules  and  approvals,
     including,  but  not  limited to  the  receipt  of  any
     necessary  approvals  by state  or  federal  regulatory
     bodies,   and   the  effectiveness  of  a  registration
     statement  under the Securities Act of 1933  if  deemed
     necessary  or appropriate by the Company.  Certificates
     for  shares  of  Common Stock issued hereunder  may  be
     legended as the Committee shall deem appropriate.

     J.   Agreements
     Each grant of Options by the Trustee shall be evidenced
     by an Agreement between the Trustee and the Participant
     which  shall  contain  such  restrictions,  terms   and
     conditions    as    the    Committee    may    require.
     Notwithstanding anything to the contrary  contained  in
     the Plan, the Company shall not be under any obligation
     to  honor  any grants under the Plan to any Participant
     hereunder  unless  such Participant shall  execute  all
     appropriate Agreements with respect to such Options  in
     such  form as the Committee may determine from time  to
     time.

     K.   Applicable Law
     The  Plan  and any related Agreements shall be governed
     in  accordance  with  the laws of the  State  of  North
     Dakota.

VIII. Establishment of Trust

The  Company  shall  establish  with  the  Trustee  a  trust
consisting   of  such  sums  of  money  or  other   property
acceptable to the Trustee as shall from time to time be paid
or  delivered to the Trustee, all investments made therewith
and  proceeds thereof and all earnings and profits  thereon.
The  Trustee  shall invest funds, if any,  advanced  by  the
Company in shares of Common Stock.  Upon the exercise of  an
Option by a Participant, the Trustee shall take Common Stock
from  the  trust or shall purchase Common Stock on the  open
market or from the Company and deliver certificates for such
shares to the Participant.

The  Company  shall have the right at any time to  terminate
the  trust but such termination shall not affect the  rights
of  any Participant to whom an Option has been granted under
the  Plan.   After effecting all purchases and transfers  of
Common  Stock  as are required by the Plan pursuant  to  the
exercise  of Options by Participants, the Trustee  shall  be
relieved of all further liability.  Termination of the trust
shall  take effect as of the date the last such transfer  is
made.   Upon  such termination any assets remaining  in  the
trust   shall  be  returned  to  the  Company  unless  other
directions are given to the Trustee by the Company.
