To Our Stockholders:

    You are cordially invited to attend the Annual Meeting of Stockholders to be
held on Tuesday, April 24, 2001, at 11:00 a.m., Central Daylight Savings Time,
at 909 Airport Road, Bismarck, North Dakota 58504. The other Directors and the
officers join me in extending this invitation.

    The formal matters to be acted upon at the meeting are described in the
accompanying Notice of Annual Meeting of Stockholders and Proxy Statement. In
addition to the formal issues, a brief report on current matters of interest
will be presented. Lunch will be served following the meeting.

    We were pleased with the response of our stockholders at the 2000 Annual
Meeting at which 77.7 percent of the Common Stock was represented in person or
by proxy. We hope that participation by our stockholders in the affairs of the
Company will increase and that there will be an even greater representation at
the 2001 meeting. If you are unable to attend the meeting but have questions or
comments on the Company's operations, we would like to hear from you.

    This year, you may vote your shares by telephone, by the Internet or by
marking, dating, signing and returning the enclosed letter proxy. Representation
of your shares at the meeting is very important. Accordingly, whether or not you
plan to attend the meeting, we urge you to submit your proxy promptly by one of
the three methods offered. If you do attend the meeting, you may, if you wish,
withdraw your proxy and vote in person.

    I hope you will find it possible to attend the meeting.

                                          Sincerely,

                                          /s/ Martin A. White

                                PROXY STATEMENT

                             ---------------------

    This Proxy Statement is furnished to the holders of Common Stock of MDU
Resources Group, Inc. (Company) on behalf of the Board of Directors of the
Company in connection with the solicitation of proxies to be used in voting at
the Annual Meeting of Stockholders to be held on April 24, 2001. The proxy
material was first forwarded to the holders of Common Stock on March 9, 2001.

    Stockholders of record may vote their proxies by Touchtone telephone by
calling the toll free telephone number on the proxy, by using the Internet, or
by marking, dating, signing and returning the enclosed letter proxy in the
envelope provided (no postage is necessary if mailed in the United States). If
your shares are held in the name of a bank or broker, you MAY be able to vote by
telephone or the Internet. Follow the instructions you receive from your bank or
broker.

    The Company has been advised by counsel that the procedures for Internet and
telephone voting are consistent with the requirements of applicable law.

    Stockholders voting through the Internet should understand that there may be
costs associated with electronic access, such as usage charges from Internet
access providers and telephone companies, that must be borne by the stockholder.

    Any stockholder giving a proxy may revoke it at any time prior to its use at
the meeting by filing with the Secretary either a written instrument of
revocation or a duly executed proxy bearing a later date. In addition, the
powers of a proxy holder are suspended if the person executing the proxy is
present at the meeting and informs the Secretary in open meeting that he wishes
to revoke his proxy and vote in person. Attendance at the meeting will not, in
and of itself, revoke a proxy.

    The Company will bear the cost of the solicitation of proxies, including the
charges and expenses of brokerage firms and others, for forwarding solicitation
material to beneficial owners of shares of the Common Stock of the Company. In
addition to the use of the mails, proxies may be solicited by officers and
regular employees of the Company, by personal interview, by telephone, or other
electronic means. Banks, brokerage houses and other institutions, nominees, and
fiduciaries will be requested to forward the soliciting material to their
principals and to obtain authorizations for the execution of the letter proxies
and will, upon request, be reimbursed for reasonable expenses incurred.
Additional solicitation of proxies will be made in the same manner under the
special engagement and direction of Georgeson & Company, Inc. at an anticipated
cost to the Company of approximately $6,500 plus out-of-pocket expenses.

                         VOTING SECURITIES OUTSTANDING

    Only holders of record of Common Stock at the close of business on
February 26, 2001, will be entitled to vote at the meeting. On such date there
were outstanding 65,725,235 shares of Common Stock. Each outstanding share of
Common Stock entitles the holder to one vote.

                                       1

    The Bylaws of the Company provide that a majority of the shares of Common
Stock issued and outstanding and entitled to vote in person or by proxy shall
constitute a quorum at a meeting of stockholders of the Company. Shares of
Common Stock represented by a properly submitted proxy are considered present
for purposes of determining a quorum. A proxy may be submitted by returning a
properly signed and dated letter proxy, by Touchtone telephone, or by the
Internet.

    Under Delaware law, if a quorum is present, the nominees for election as
Directors who receive a plurality of the votes of shares present in person or
represented by proxy and entitled to vote shall be elected as Directors.
"Withheld" votes are not included in the total vote cast for a nominee for
purposes of determining whether a plurality was received and, therefore, have no
negative effect.

    The proposed amendments to the 1997 Executive Long-Term Incentive Plan for
New York Stock Exchange and Internal Revenue Code purposes require the
affirmative vote of the holders of a majority of the votes cast, provided that
the total votes cast represent over 50 percent in interest of all securities
entitled to vote on the amendments. Under the laws of the State of Delaware, the
Plan amendments require the affirmative vote of the holders of a majority of the
Common Stock present or represented by proxy and entitled to vote. Abstentions
will have the effect of a vote against the amendments and broker non-votes will
have no effect. For the purpose of determining whether the number of votes cast
represents more than 50 percent of the shares of Common Stock entitled to vote,
abstentions will count as votes cast and broker non-votes will not count as
votes cast.

    As of February 26, 2001, no person other than New York Life Trust Company
held of record, or, to the knowledge of the management of the Company, owned
beneficially, 5 percent or more of the outstanding shares of Common Stock of the
Company. New York Life Trust Company, Norwood, MA, held approximately
9.1 percent of the outstanding Common Stock of the Company as trustee of the
Company's Tax Deferred Compensation Savings Plans. New York Life Trust Company
disclaims all beneficial ownership of these shares.

                             ELECTION OF DIRECTORS

    Three of the Company's directors have retired or are retiring this year:
Richard L. Muus, San W. Orr, Jr., and John A. Schuchart.

    Mr. Muus, who was first elected to the Board in 1985, has reached age 70 and
is not standing for reelection. He currently serves on the Audit Committee and
as chairman of the Finance Committee.

    Mr. Orr retired from the Board on November 14, 2000. Mr. Orr was elected to
the Board in 1978. He served most recently on the Audit Committee and as
chairman of the Compensation Committee.

    Mr. Schuchart retired as Chairman of the Board on January 12, 2001, his 25th
anniversary with the Company.

    The Company thanks each of these men for their many years of distinguished
service to MDU Resources Group, Inc.

    At the meeting, four Directors will be elected to serve for a term of three
years until 2004, and one Director will be elected to serve a term of one year
until 2002, and until their respective successors are elected and qualify. All
of the nominees are incumbent Directors and are nominated for reelection. Unless
otherwise specified when the proxy is submitted, shares of the Common Stock
represented by the proxy will be voted for the nominees named below. If any
nominee becomes unavailable for any reason, or if a vacancy should occur before
the election (which events are not anticipated), the shares represented by the
proxy will be voted for another person in the discretion of the persons named in
the proxy. Information

    During 2000, the Board of Directors had seven meetings. The Board of
Directors has an Audit Committee, a Compensation Committee, a Finance Committee,
and a Nominating Committee. All Committees are composed entirely of outside
Directors. The Audit Committee, established in 1972, meets regularly with
management, internal auditors, and representatives of the Company's independent
public accountants. During 2000, the Committee met four times. The Compensation
Committee, which met four times during 2000, sets compensation levels for
executive officers and recommends to the full Board of Directors compensation
for the Directors of the Company. The Finance Committee, which met seven times
during 2000, reviews corporate financial plans, policies, budgets, investments
and acquisitions, and reviews and authorizes actions necessary to issue and sell
Common Stock and debt securities of the Company. The Nominating Committee, which
met three times during 2000, recommends to the full Board of Directors nominees
for Director. All incumbent Directors attended more than 75 percent of the
combined total of the meetings of the Board and of the Committees on which the
Director served.

         PROPOSAL TO AMEND THE 1997 EXECUTIVE LONG-TERM INCENTIVE PLAN

    The 1997 Executive Long-Term Incentive Plan (the "LTIP") was approved by the
stockholders at the 1997 Annual Meeting, and Internal Revenue Code Section
162(m) amendments to the LTIP were approved at the 2000 Annual Meeting. On
February 15, 2001, the Board of Directors approved amendments to the plan to
(i) increase the number of shares of stock that may be granted under the LTIP by
4,000,000 (to fund the LTIP for the next few years) and (ii) to increase the
annual limit on grants to covered employees under the plan for purposes of
Section 162(m) of the Internal Revenue Code (the "Code"). In accordance with the
requirements of the New York Stock Exchange and Section 162(m) of the Code, the
stockholders must also approve the LTIP amendments.

    The complete text of the LTIP as amended is set forth as Exhibit "A" hereto.
The following is a summary of the material features of the LTIP and is qualified
in its entirety by reference to Exhibit "A".

PURPOSE OF THE LTIP

    The purpose of the LTIP is to promote the success and enhance the value of
the Company by linking the personal interests of officers and key employees to
those of the Company's stockholders and customers. The LTIP is further intended
to assist the Company in its ability to motivate, attract and retain highly
qualified individuals to serve as officers and key employees of the Company.

EFFECTIVE DATE AND DURATION

    The LTIP became effective on April 22, 1997, and remains in effect, subject
to the right of the Board of Directors to terminate the LTIP at any time, until
all shares subject to the LTIP shall have been purchased or acquired; provided,
however, that no awards may be made after the tenth anniversary of the effective
date.

AMENDMENTS

    The Board may, at any time and from time to time, alter, amend, suspend or
terminate the LTIP in whole or in part, subject to certain restrictions as
stated in the LTIP.

ADMINISTRATION OF THE LTIP

    The LTIP is administered by the Compensation Committee of the Board or by
any other committee appointed by the Board of Directors (the "Committee").

SHARES SUBJECT TO THE LTIP

    When it became effective, the LTIP authorized the grant of up to 1,200,000
shares of MDU Resources Group, Inc. common stock. At February 26, 2001, after
giving effect to stock splits and grants pursuant to the LTIP, 385,709 shares
remain available for issuance. On February 15, 2001, the Board of Directors
approved an increase of 4,000,000 shares of common stock for the LTIP, subject
to stockholder approval at the 2001 Annual Meeting. Shares underlying awards
that lapse or are forfeited may be reused for subsequent awards. Shares may be
authorized but unissued shares of common stock, treasury stock or shares
purchased on the open market. The market value of a share of Company common
stock as of December 31, 2000 was $32.50.

    If a stock split, stock dividend or other corporate transaction occurs that
causes a change in the capitalization of the Company, the Committee shall make
appropriate adjustments to the number and class of shares of common stock that
may be granted under the LTIP and the number and class and/or price of shares of
common stock subject to outstanding awards under the LTIP, as it deems
appropriate and equitable to prevent dilution or enlargement of participants'
rights.

                                       7

ELIGIBILITY AND PARTICIPATION

    Employees eligible to participate in the LTIP include all officers and key
employees of the Company and its business units, as determined by the Committee,
including employees who are members of the Board of Directors, but excluding
directors who are not employees. The approximate number of employees who are
currently eligible to participate under the LTIP is 130.

GRANTS UNDER THE LTIP

    SECTION 162(m).  Stock options, SARs and performance unit/performance share
awards are intended to qualify for deductibility under Section 162(m) of the
Code. Dividend equivalents, restricted stock, restricted stock units and other
awards may qualify for deductibility.

    The Board of Directors approved an increase in the individual annual limit
on grants to covered employees, from 300,000 to 1,000,000 shares ($6,000,000 for
dividend equivalents), subject to stockholder approval at the 2001 Annual
Meeting. The total number of shares with respect to which options or SARs may be
granted in any calendar year to any covered employee under Section 162(m) of the
Code shall not exceed 1,000,000 shares; (ii) the total number of shares of
restricted stock that are intended to qualify for deduction that may be granted
in any calendar year to any covered employee shall not exceed 1,000,000 shares;
(iii) the total number of performance shares or performance units that may be
granted in any calendar year to any covered employee shall not exceed 1,000,000
shares or units, as the case may be; (iv) the total number of shares that are
intended to qualify for deduction granted pursuant to Article 10 of the Plan in
any calendar year to any covered employee shall not exceed 1,000,000 shares;
(v) the total cash award that is intended to qualify for deduction that may be
paid pursuant to Article 10 of the Plan in any calendar year to any covered
employee shall not exceed $6,000,000; and (vi) the aggregate number of dividend
equivalents that are intended to qualify for deduction that a covered employee
may receive in any calendar year shall not exceed $6,000,000.

    A "covered employee" means those persons specified in Section 162(m) of the
Code--generally the chief executive officer and the next four most
highly-compensated officers.

    STOCK OPTIONS.  The Committee may grant incentive stock options ("ISOs"),
nonqualified stock options ("NQSOs") or a combination thereof under the LTIP.
The exercise price for each such award shall be not less than the average of the
high and low sale prices of Company common stock on the date of grant. Options
shall expire at such times and shall have such other terms and conditions as the
Committee may determine at the time of grant, provided, however, that no ISO
shall be exercisable later than the tenth anniversary of its grant. Dividend
equivalents may also be granted.

    The option exercise price is payable in cash, in shares of common stock of
the Company having a fair market value equal to the exercise price, by share
withholding, cashless exercise or any combination of the foregoing.

    STOCK APPRECIATION RIGHTS.  SARs granted under the LTIP may be in the form
of freestanding SARs, tandem SARs or a combination thereof. The base value of a
freestanding SAR shall be equal to the average of the high and low sale prices
of a share of Company common stock on the date of grant. The base value of a
tandem SAR shall be equal to the option exercise price of the related option.

    Freestanding SARs may be exercised upon such terms and conditions as are
imposed by the Committee and as set forth in the SAR award agreement. A tandem
SAR may be exercised only with respect to the shares of common stock of the
Company for which its related option is exercisable.

    Upon exercise of an SAR, a participant will receive the product of the
excess of the fair market value of a share of Company common stock on the date
of exercise over the base value multiplied by the number of shares with respect
to which the SAR is exercised. Payment due to the participant upon exercise may
be

                                       8

made in cash, in shares of Company common stock having a fair market value equal
to such cash amount, or in a combination of cash and shares, as determined by
the Committee.

    RESTRICTED STOCK.  Restricted stock may be granted in such amounts and
subject to such terms and conditions as determined by the Committee. The
Committee may establish performance goals, as described below, for restricted
stock.

    Participants holding restricted stock may exercise full voting rights with
respect to those shares during the restricted period and, subject to the
Committee's right to determine otherwise at the time of grant, will receive
regular cash dividends. All other distributions paid with respect to the
restricted stock shall be credited subject to the same restrictions on
transferability and forfeitability as the shares of restricted stock with
respect to which they were paid.

    PERFORMANCE UNITS AND PERFORMANCE SHARES.  Performance units and performance
shares may be granted in the amounts and subject to such terms and conditions as
determined by the Committee. The Committee shall set performance goals, which,
depending on the extent to which they are met during the performance periods
established by the Committee, will determine the number and/or value of
performance units/shares that will be paid out to participants.

    Participants shall receive payment of the value of performance units/shares
earned after the end of the performance period. Payment of performance
units/shares shall be made in cash and/or shares of common stock which have an
aggregate fair market value equal to the value of the earned performance
units/shares at the end of the applicable performance period, in such
combination as the Committee determines. Such shares may be granted subject to
any restrictions deemed appropriate by the Committee.

    OTHER AWARDS.  The Committee may make other awards which may include,
without limitation, the grant of shares of common stock based upon attainment of
performance goals established by the Committee as described below, the payment
of shares in lieu of cash or cash based on performance goals and the payment of
shares in lieu of cash under other Company incentive or bonus programs.

PERFORMANCE GOALS

    Performance goals, which are established by the Committee, will be based on
one or more of the following measures: sales or revenues, earnings per share,
shareholder return and/or value, funds from operations, operating income, gross
income, net income, cash flow, return on equity, return on capital, earnings
before interest, operating ratios, stock price, customer satisfaction,
accomplishment of mergers, acquisitions, dispositions or similar extraordinary
business transactions, profit returns and margins, financial return ratios
and/or market performance. Performance goals may be measured solely on a
corporate, subsidiary or business unit basis, or a combination thereof.
Performance goals may reflect absolute entity performance or a relative
comparison of entity performance to the performance of a peer group of entities
or other external measure.

TERMINATION OF EMPLOYMENT

    Each award agreement shall set forth the participant's rights with respect
to each award following termination of employment with the Company.

TRANSFERABILITY

    Except as otherwise determined by the Committee at the time of grant and
subject to the provisions of the LTIP, awards may not be sold, transferred,
pledged, assigned or otherwise alienated or hypothecated, other than by will or
by the laws of descent and distribution, and a participant's rights shall be
exercisable only by the participant or the participant's legal representative
during his or her lifetime.

                                       9

CHANGE IN CONTROL

    Upon a change in control, as defined below,

    (a) Any and all options and SARs granted under the LTIP shall become
       immediately exercisable;

    (b) Any restriction periods and restrictions imposed on restricted stock
       shall be deemed to have expired; any performance goals shall be deemed to
       have been met at the target level; and such restricted stock shall become
       immediately vested in full; and

    (c) The target payout opportunity attainable under all outstanding awards of
       performance units, performance shares and other awards shall be deemed to
       have been fully earned for the entire performance period(s) as of the
       effective date of the change in control. The vesting of all awards
       denominated in shares shall be accelerated as of the effective date of
       the change in control, and there shall be paid out in cash to
       participants immediately following the effective date of the change in
       control the full amount of the targeted cash payout opportunities
       associated with outstanding cash-based awards.

    A change in control of the Company means the earliest of the following
events to occur: (i) the public announcement by the Company or by any person
(which shall not include the Company, any subsidiary of the Company, or any
employee benefit plan of the Company or of any subsidiary of the Company)
("Person") that such Person, who or which, together with all Affiliates and
Associates (within the meanings ascribed to such terms in the Rule 12b-2 of the
General Rules and Regulations under the Securities Exchange Act of 1934, as
amended) of such Person, shall be the beneficial owner of twenty percent (20%)
or more of the voting stock of the Company outstanding; (ii) the commencement
of, or after the first public announcement of any Person to commence, a tender
or exchange offer the consummation of which would result in any Person becoming
the beneficial owner of voting stock aggregating thirty percent (30%) or more of
the then outstanding voting stock of the Company; (iii) the announcement of any
transaction relating to the Company required to be described pursuant to the
requirements of Item 6(e) of Schedule 14A of Regulation 14A under the Exchange
Act; (iv) a proposed change in constituency of the Board such that, during any
period of two (2) consecutive years, individuals who at the beginning of such
period constitute the Board cease for any reason to constitute at least a
majority thereof, unless the election or nomination for election by the
stockholders of the Company of each new Director was approved by a vote of at
least two-thirds ( 2/3) of the Directors then still in office who were members
of the Board at the beginning of the period; or (v) any other event which shall
be deemed by a majority of the Committee to constitute a "change in control".

    Options were granted in 2001 for the 2001-2003 award cycle. The options are
performance accelerated with a ten year term; they vest nine years after grant,
but vesting may be accelerated upon achievement of performance goals established
by the Committee over the three-year performance period. Dividend equivalents
were also granted. The exercise price is fair market value on the date of grant.

FEDERAL INCOME TAX CONSEQUENCES

    The following is a brief description of the principal federal income tax
consequences relating to options awarded under the LTIP. This summary is based
on the Company's understanding of present federal income tax law and
regulations. The summary does not purport to be complete or applicable to every
specific situation.

CONSEQUENCES TO THE OPTIONHOLDER

    GRANT.  There are no federal income tax consequences to the optionholder
solely by reason of the grant of ISOs or NQSOs under the LTIP.

                                       11

    EXERCISE.  The exercise of an ISO is not a taxable event for regular federal
income tax purposes if certain requirements are satisfied, including the
requirement that the optionholder generally must exercise the ISO no later than
three months following the termination of the optionholder's employment with the
Company. However, such exercise may give rise to alternative minimum tax
liability (see "Alternative Minimum Tax" below).

    Upon the exercise of a NQSO, the optionholder will generally recognize
ordinary income in an amount equal to the excess of the fair market value of the
shares of Company common stock at the time of exercise over the amount paid
therefor by the optionholder as the exercise price. The ordinary income, if any,
recognized in connection with the exercise by an optionholder of a NQSO will be
subject to both wage and employment tax withholding.

    The optionholder's tax basis in the shares acquired pursuant to the exercise
of an option will be the amount paid upon exercise plus, in the case of a NQSO,
the amount of ordinary income, if any, recognized by the optionholder upon
exercise thereof.

    QUALIFYING DISPOSITION.  If an optionholder disposes of shares of Company
common stock acquired upon exercise of an ISO in a taxable transaction, and such
disposition occurs more than two years from the date on which the option was
granted and more than one year after the date on which the shares were
transferred to the optionholder pursuant to the exercise of the ISO, the
optionholder will recognize long-term capital gain or loss equal to the
difference between the amount realized upon such disposition and the
optionholder's adjusted basis in such shares (generally the option exercise
price).

    DISQUALIFYING DISPOSITION.  If the optionholder disposes of shares of
Company common stock acquired upon the exercise of an ISO (other than in certain
tax-free transactions) within two years from the date on which the ISO was
granted or within one year after the transfer of shares to the optionholder
pursuant to the exercise of the ISO, at the time of disposition the optionholder
will generally recognize ordinary income equal to the lesser of (i) the excess
of each such share's fair market value on the date of exercise over the exercise
price paid by the optionholder or (ii) the optionholder's actual gain (I.E., the
excess, if any, of the amount realized on the disposition over the exercise
price paid by the optionholder). If the total amount realized on a taxable
disposition (including return of capital and capital gain) exceeds the fair
market value on the date of exercise of the shares of Company common stock
purchased by the optionholder under the option, the optionholder will recognize
a capital gain in the amount of such excess. If the optionholder incurs a loss
on the disposition (i.e., if the total amount realized is less than the exercise
price paid by the optionholder), the loss will be a capital loss.

    OTHER DISPOSITION.  If an optionholder disposes of shares of Company common
stock acquired upon exercise of a NQSO in a taxable transaction, the
optionholder will recognize capital gain or loss in an amount equal to the
difference between the optionholder's basis (as discussed above) in the shares
sold and the total amount realized upon disposition. Any such capital gain or
loss (and any capital gain or loss recognized on a disqualifying disposition of
shares of Company common stock acquired upon exercise of ISOs as discussed
above) will be short-term or long-term depending on whether the shares of
Company common stock were held for more than one year from the date such shares
were transferred to the optionholder.

    ALTERNATIVE MINIMUM TAX.  Alternative minimum tax ("AMT") is payable if and
to the extent the amount thereof exceeds the amount of the taxpayer's regular
tax liability, and any AMT paid generally may be credited against future regular
tax liability (but not future AMT liability). AMT applies to alternative minimum
taxable income; generally, regular taxable income, subject to certain
adjustments and increased by items of tax preference, is treated differently
under the AMT.

    For AMT purposes, the spread upon exercise of an ISO (but not a NQSO) will
be included in alternative minimum taxable income, and the taxpayer will receive
a tax basis equal to the fair market value of the shares of Company common stock
at such time for subsequent AMT purposes. However, if the

                                       12

optionholder disposes of the ISO shares in the year of exercise, the AMT income
cannot exceed the gain recognized for regular tax purposes, provided that the
disposition meets certain third-party requirements for limiting the gain on a
disqualifying disposition. If there is a disqualifying disposition in a year
other than the year of exercise, the income on the disqualifying disposition is
not considered alternative minimum taxable income.

CONSEQUENCES TO THE COMPANY

    There are no federal income tax consequences to the Company by reason of the
grant of ISOs or NQSOs or the exercise of an ISO (other than disqualifying
dispositions).

    At the time the optionholder recognizes ordinary income from the exercise of
a NQSO, the Company will be entitled to a federal income tax deduction in the
amount of the ordinary income so recognized (as described above), provided that
the Company satisfies its reporting obligations described below. To the extent
the optionholder recognizes ordinary income by reason of a disqualifying
disposition of the stock acquired upon exercise of an ISO, the Company will be
entitled to a corresponding deduction in the year in which the disposition
occurs.

    The Company will be required to report to the Internal Revenue Service any
ordinary income recognized by any optionholder by reason of the exercise of a
NQSO. The Company will be required to withhold income and employment taxes (and
pay the employer's share of employment taxes) with respect to ordinary income
recognized by the optionholder upon the exercise of NQSOs.

OTHER TAX CONSEQUENCES

    The foregoing discussion is not a complete description of the federal income
tax aspects of options granted under the LTIP. In addition, administrative and
judicial interpretations of the application of the federal income tax laws are
subject to change. Furthermore, the foregoing discussion does not address state
or local tax consequences.

         THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THIS PROPOSAL.

    The proposed amendments to the LTIP for New York Stock Exchange and Internal
Revenue Code purposes require the affirmative vote of the holders of a majority
of the votes cast, provided that the total votes cast represent over 50 percent
in interest of all securities entitled to vote on the amendments. Under the laws
of the State of Delaware, the LTIP amendments require the affirmative vote of
the holders of a majority of the Common Stock present or represented by proxy
and entitled to vote. Abstentions will have the effect of a vote against the
amendments and broker non-votes will have no effect. For the purposes of
determining whether the number of votes cast represents more than 50 percent of
the shares of Common Stock entitled to vote, abstentions will count as votes
cast and broker non-votes will not count as votes cast.

    If a choice has been specified by a stockholder by means of the proxy, the
shares of common stock will be voted accordingly. If no choice has been
specified, the shares will be voted "FOR" the proposal.

    The Table covers the amounts payable under the Salaried Pension Plan and
non-qualified Supplemental Income Security Plan (SISP). Pension benefits are
determined by the step-rate formula which places emphasis on the highest
consecutive 60 months of earnings within the final 10 years of service. Benefits
for single participants under the Salaried Pension Plan are paid as straight
life amounts and benefits for married participants are paid as actuarially
reduced pensions with a survivorship benefit for spouses, unless participants
choose otherwise. The Salaried Pension Plan also permits preretirement
survivorship benefits upon satisfaction of certain conditions. Additionally,
certain reductions are made for employees electing early retirement.

    The Internal Revenue Code places maximum limitations on the amount of
benefits that may be paid under the Salaried Pension Plan. The Company has
adopted a non-qualified SISP for senior management personnel. In 2000, 81 senior
management personnel participated in the SISP, including the Named Officers.
Both plans cover salary shown in column (c) of the Summary Compensation Table
and exclude bonuses and other forms of compensation.

    Upon retirement and attainment of age 65, participants in the SISP may elect
a retirement benefit or a survivors' benefit with the benefits payable monthly
for a period of 15 years.

    As of December 31, 2000, the Named Officers were credited with the following
years of service under the plans: Mr. White: Pension, 9, SISP, 9; Mr. Kane:
Pension, 29, SISP, 19; Mr. Tipton: Pension, 17,

                                       15

SISP, 17; Mr. Robinson: Pension 12, SISP 12; and Mr. Loble: Pension, 13, SISP,
13. The maximum years of service for benefits under the Pension Plan is 35 and
under the SISP vesting begins at 3 years and is complete after 10 years. Benefit
amounts under both plans are not subject to reduction for offset amounts.

                         CHANGE-OF-CONTROL ARRANGEMENTS

    The Company entered into Change of Control Employment Agreements with the
Named Officers in November 1998, which would become effective for a three-year
period (with automatic annual extension if the Company does not provide
nonrenewal notice at least 60 days prior to the end of each 12-month period)
only upon a change of control of the Company. If a change of control occurs, the
agreements provide for a three-year employment period from the date they become
effective, with base salary not less than the highest amount paid within the
preceding twelve months, an annual bonus not less than the highest bonus paid
within the preceding three years, and participation in the Company's incentive,
savings, retirement and welfare benefit plans.

    The agreements also provide that specified payments and benefits would be
paid in the event of termination of employment of the Named Officer by the
Company, other than for cause or disability, or by the Named Officer for good
reason at any time when the agreements are in effect. In such event, each of the
Named Officers would receive payment of an amount equal to three times his
annual base pay plus three times his highest annual bonus (as defined therein).
In addition, under these agreements, each of the officers would receive (i) an
immediate pro-rated cash-out of his bonus for the year of termination based on
the highest annual bonus and (ii) an amount equal to the excess of (a) the
actuarial equivalent of the benefit under Company qualified and nonqualified
retirement plans that the executive would receive if he continued employment
with the Company for an additional three years over (b) the actual benefit paid
or payable under these plans. All benefits of each executive officer under the
Company's welfare benefit plans would continue for at least three years. These
arrangements also provide for certain gross-up payments to compensate these
executive officers for any excise taxes incurred in connection with these
benefits and reimbursement for certain outplacement services.

    For these purposes, "cause" means the Named Officer's willful and continued
failure to substantially perform his duties or willfully engaging in illegal
conduct or misconduct materially injurious to the Company, and "good reason"
includes the Company's termination of the Named Officer without cause, the
assignment to the Named Officer of duties inconsistent with his prior status and
position, certain reductions in compensation or benefits, and relocation or
increased travel obligations.

    A "change of control" is defined as (i) the acquisition by a party or
certain related parties of 20% or more of the Company's voting securities;
(ii) a turnover in a majority of the Board of Directors without the approval of
a majority of the members of the Board as of November 1998; (iii) a merger or
similar transaction after which the Company's stockholders hold 60% or less of
the voting securities of the surviving entity; or (iv) the stockholders'
approval of the liquidation or dissolution of the Company.

            COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

INTRODUCTION

    The Compensation Committee of the Board of Directors is responsible for
determining the compensation of the Company's executive officers. Composed
entirely of non-employee Directors, the Committee meets several times each year
to review and determine compensation for the executive officers, including the
Chief Executive Officer.

EXECUTIVE COMPENSATION

    The Committee firmly believes that appropriate compensation levels succeed
in both attracting and motivating high quality employees. To implement this
philosophy, the Committee analyzes trends in

                                       16

compensation among comparable companies participating in the oil and gas
industry, segments of the energy and mining industries, the peer group of
companies used in the graph following this report, and similar companies from
general industry. The Committee then sets compensation levels that it believes
are competitive within the industry and structured in a manner that rewards
successful performance on the job. There are three components of total executive
compensation: base salary, annual incentive compensation, and long-term
incentive compensation.

    In setting base salaries, the Committee does not use a particular formula.
In addition to the data referenced above, other factors the Committee uses in
its analysis include the executive's current salary in comparison to the
competitive industry standard as well as individual performance. Using this
system, the Committee granted to Mr. White, the President and Chief Executive
Officer, a 20.5% increase in base salary for 2000. This increase took into
account Mr. White's personal performance during 2000, his time as chief
executive officer, and comparative industry data. During 2000, only
approximately 34.6% of Mr. White's compensation was base pay. The remainder was
performance-based. This reflects the Committee's belief in the importance of
having substantial at risk compensation to provide a direct and strong link
between performance and executive pay. The other Named Officers received base
salary increases averaging 8.28% for 2000.

    In keeping with the Committee's belief that compensation should be directly
linked to successful performance, the Company employs both annual and long-term
incentive compensation plans. The annual incentive compensation is determined
under the Executive Incentive Compensation Plan. The Committee makes awards
based upon the level of corporate earnings, cost efficiency, and individual
performance. Mr. White received a total of $333,239 (or 150.9% of the targeted
amount) in annual incentive compensation for 2000; the other Named Officers
received an average of $116,864, or 149.3% of the targeted amount, based upon
achievement of corporate earnings and individual performance near the maximum
level.

    Long-term incentive compensation serves to encourage successful strategic
management and is determined through two different vehicles: the 1992 Key
Employee Stock Option Plan and the 1997 Executive Long-Term Incentive Plan.
Options with a three-year performance cycle (1998-2000) and related dividend
equivalents were granted under the 1992 Key Employee Stock Option Plan in 1998.
Performance goals established by the Committee and described in the 1999 Proxy
Statement for the 1998-2000 performance cycle were exceeded; therefore,
exercisability of the options was accelerated and dividend equivalents were
earned at 130.0%. No additional options were granted in 2000.

    Restricted stock awards were made in 2000 to Mr. White and the other Named
Officers under the 1997 Executive Long-Term Incentive Plan. The restricted stock
is performance accelerated; it vests automatically within nine years; however,
vesting may be accelerated if total shareholder return on MDU Resources stock
meets or exceeds the 50th percentile of the peer group (as shown in the
performance graph). The number of shares granted was to raise overall
compensation levels closer to the median (although still slightly below) level
of compensation within the industry. The restricted stock serves to motivate
long-term performance and to align the interests of the executives with those of
stockholders.

    In 1994, the Board of Directors adopted Stock Ownership Guidelines under
which executives are required to own Company Common Stock valued from one to
four times their annual salary.

    The 2000 compensation paid to the Company's executive officers qualified as
fully deductible under federal tax laws. The Committee continues to review the
impact of federal tax laws on executive compensation, including Section 162(m)
of the Internal Revenue Code.

   the peer group. Total stockholder return is calculated using the December 31
   price for each year. It is assumed that all dividends are reinvested in stock
   at the frequency paid, and the returns of each component peer issuer of the
   group is weighted according to the issuer's stock market capitalization at
   the beginning of the period. Peer Group issuers are Allete (formerly
   Minnesota Power, Inc.), Black Hills Corporation, Coastal Corporation,
   Equitable Resources, Inc., LG&E Energy Corp., The Montana Power Company,
   NorthWestern Corporation, ONEOK, Inc., Otter Tail Power Company, Questar
   Corporation, and UGI Corporation. LG&E Energy Corp. merged with Powergen PLC
   and discontinued trading on December 11, 2000. However, value as of this date
   was included for total return purposes at December 31, 2000.

                            DIRECTORS' COMPENSATION

    Each Director who is not an officer of the Company (except the Chairman of
the Board) receives $13,000 and 450 shares of Company Common Stock as an annual
retainer for Board service. The Chairman receives $52,000 and 450 shares of
Company Common Stock. Audit and Nominating Committee Chairmen each receive a
$2,500 annual retainer, and Finance and Compensation Committee Chairmen each
receive a $4,000 annual retainer. Additionally, each Director who is not an
officer of the Company receives $1,000 for each meeting of the Board of
Directors attended and each Committee member who is not an officer of the
Company receives $1,000 for each Committee meeting attended. All Directors
except the Chairman of the Board must defer $1,000 of the retainer, which amount
is credited to a deferral account quarterly. The deferral amount is divided by
the market price of Company Common Stock and converted to investment units. If
dividends are paid on Company Common Stock then an equivalent amount is credited
for each investment unit and the resulting amount is converted to investment
units and credited to such Directors' accounts. After a participating Director
leaves the Board, dies, or becomes disabled, then the investment units credited
to that Director's account are multiplied times the market price of the Company
Common Stock, converted to a dollar value, and paid to the Director or named
beneficiary in equal monthly payments (with interest) over a five year period.
Of the remaining cash retainer, each Director may direct the retainer be paid in
one or a combination of the following forms: (1) deferred into the account
described, (2) Company stock, or (3) cash. Each Director who is not an officer
of the Company received on May 12, 2000, an option to purchase 2,250 shares of
Company Common Stock. The option award vested immediately and is exercisable for
10 years from the date of grant. The exercise price is $21.625, the fair market
value of the stock on the date of the grant.

    The Company also has a post-retirement arrangement for Directors who are not
officers or retired officers of the Company which provides that after retirement
from the Board, a Director is entitled to receive an annual amount equal to the
sum of all annual retainers in effect at the time of retirement. Such amount
will be paid to the Director or named beneficiary in equal monthly installments
over a period of time equal to the period of service on the Board.

    The Company also has a program whereby past Directors of the Company may be
chosen each year as "Director Emeritus" and each such past Director so chosen
may be invited to participate as a nonvoting member of the Company's Board of
Directors. Each such "Director Emeritus" serves for five years and receives no
compensation, other than reimbursement by the Company for reasonable travel
expenses in connection with attendance at meetings of the Company's Board of
Directors.

            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

    Based solely upon a review of the Forms 3, 4 and 5 submitted to the Company
during and with respect to calendar year 2000, or written representations that
no Forms 5 were required, the Company believes that all such reports were timely
filed except that Mr. Thomas Everist, a director, filed late one report on Form
4 reporting one transaction.

                   INFORMATION CONCERNING EXECUTIVE OFFICERS

    Executive officers of the Company are elected by the Board of Directors and
serve until the next annual meeting of the Board. Any executive officer so
elected may be removed at any time by the affirmative vote of a majority of the
Board. Certain information concerning such executive officers, including their

                        ACCOUNTING AND AUDITING MATTERS

    Upon recommendation of the Audit Committee, the Board of Directors has
selected and employed the firm of Arthur Andersen LLP as the Company's
independent certified public accountants to audit its financial statements for
the fiscal year 2000. The Audit Committee is presently composed of
Messrs. Dennis W. Johnson, Richard L. Muus, John L. Olson, Harry J. Pearce, and
Homer A. Scott, Jr. (Chairman). This will be the fifteenth year in which the
firm has acted in this capacity. A representative of Arthur Andersen will be
present at the Annual Meeting of Stockholders. It is not anticipated that the
representative will make a prepared statement at the meeting. However, he or she
will be free to do so if he or she so chooses, as well as responding to
appropriate questions.

                             AUDIT COMMITTEE REPORT

    The Audit Committee of the Board of Directors is composed of five
non-employee directors of the Company. A sixth non-employee member, San W. Orr,
retired from the Board of Directors effective November 14, 2000. All members are
independent as defined in the applicable New York Stock Exchange listing
standards. The Committee held four meetings during 2000.

    The Audit Committee is governed by a written charter adopted in 1979 and
reissued on May 11, 2000. The Audit Committee Charter is included as Exhibit "B"
to the Proxy Statement.

    In connection with the December 31, 2000 financial statements, the Audit
Committee has (1) reviewed and discussed the audited financial statements with
management; (2) discussed with the independent auditors the matters required to
be discussed by SAS 61 (Codification of Statements on Auditing Standards, AU
Section 380); (3) received the written disclosures and the letter from the
independent accountants required by Independence Standards Board Standard No. 1
(Independence Discussions with

                                       22

Audit Committees), and discussed with the independent accountant the independent
accountant's independence.

    Based on the review and discussions referred to in items (1) through (3) of
the above paragraph, the Audit Committee recommended to the Board of Directors
that the audited financial statements be included in the Company's Annual Report
on Form 10-K for the last fiscal year for filing with the Securities and
Exchange Commission.

    The Audit Committee has considered whether the provision of services covered
in Items 9(e)(2) and (e)(3) of Schedule 14A under the Securities Exchange Act of
1934 is compatible with maintaining the independence of Arthur Andersen LLP. The
Committee believes that the fees billed by Arthur Andersen LLP for the services
set forth below are compatible with Arthur Andersen LLP maintaining its
independence as the Company's principal accountant.

                                   AUDIT FEES

    The aggregate fees billed or expected to be billed by Arthur Andersen LLP
for professional services rendered for the audit of the Company's annual
financial statements for 2000 and the reviews of the financial statements
included in the Company's Forms 10-Q for 2000 are $444,500.

          FINANCIAL INFORMATION SYSTEMS DESIGN AND IMPLEMENTATION FEES

    There were no fees billed by Arthur Andersen LLP for 2000 for the
professional services described in Paragraph (c)(4)(ii) of Rule 2-01 of
Regulation S-X.

                                 ALL OTHER FEES

    The aggregate fees billed or expected to be billed for services rendered by

                      2002 ANNUAL MEETING OF STOCKHOLDERS

    Under the Company's Bylaws, nominations for Director may be made only by the
Board or the Nominating Committee, or by a stockholder entitled to vote who has
delivered written notice to the Secretary of the Company (containing certain
information specified in the Bylaws) not less than 120 days prior to the
anniversary of the date on which the Company first mailed its proxy materials
for the prior year's annual meeting. The Bylaws also provide that no business
may be brought before an annual meeting of the stockholders except as specified
in the notice of the meeting or as otherwise properly brought before the meeting
by or at the direction of the Board or by a stockholder entitled to vote who has
delivered written notice to the Secretary of the Company (containing certain
information specified in the Bylaws) not less than 120 days prior to the
anniversary of the date on which the Company first mailed its proxy materials

                                       23

    Rule 14a-4 of the Securities and Exchange Commission's proxy rules allows

before an annual meeting of stockholders, if the Company does not have notice of
the matter at least 45 days before the anniversary of the date on which the
Company first mailed its proxy materials for the prior year's annual meeting of
stockholders or the date specified by an advance notice provision in the
Company's Bylaws. The Company's Bylaws contain such an advance notice provision
as decribed above. For the Company's Annual Meeting of Stockholders expected to
be held on April 23, 2002, stockholders must submit such written notice to the
Secretary of the Company on or before November 9, 2001.

    These requirements are separate and apart from and in addition to the
Securities and Exchange Commission's requirements that a stockholder must meet

Statement under Rule 14a-8 of the Exchange Act. For purposes of the Company's
Annual Meeting of Stockholders expected to be held on April 23, 2002, any

Plan; to construe and interpret the Plan and any agreement or instrument entered

Awards granted under the Plan, as may be determined to be appropriate and
equitable by the Committee, in its sole discretion, to prevent dilution or

ARTICLE 6. STOCK OPTIONS

    6.1  GRANT OF OPTIONS.  Subject to the terms and conditions of the Plan,
Options may be granted to an Eligible Employee at any time and from time to
time, as shall be determined by the Committee.

    The Committee shall have complete discretion in determining the number of
Shares subject to Options granted to each Participant (subject to Article 4
herein) and, consistent with the provisions of the Plan, in determining the
terms and conditions pertaining to such Options. The Committee may grant ISOs,
NQSOs, or a combination thereof.

    6.2  OPTION AWARD AGREEMENT.  Each Option grant shall be evidenced by an
Option Award Agreement that shall specify the Option Price, the term of the
Option, the number of Shares to which the Option pertains, the Exercise Period
and such other provisions as the Committee shall determine, including but not
limited to any rights to Dividend Equivalents. The Option Award Agreement shall
also specify whether the Option is intended to be an ISO or an NQSO.

    The Option Price for each Share purchasable under any Incentive Stock Option
granted hereunder shall be not less than one hundred percent (100%) of the Fair
Market Value per Share at the date the Option is granted; and provided, further,
that in the case of an Incentive Stock Option granted to a person who, at the
time such Incentive Stock Option is granted, owns shares of stock of the Company
or of any Subsidiary which possess more than ten percent (10%) of the total
combined voting power of all classes of shares of stock of the Company or of any
Subsidiary, the Option Price for each Share shall be not less than one hundred
ten percent (110%) of the Fair Market Value per Share at the date the Option is
granted. The Option Price will be subject to adjustment in accordance with the
provisions of Section 4.2 of the Plan.

    No Incentive Stock Option by its terms shall be exercisable after the
expiration of ten (10) years from the date of grant of the Option; provided,
however, in the case of an Incentive Stock Option granted to a person who, at
the time such Option is granted, owns shares of stock of the Company or of any
Subsidiary possessing more than ten percent (10%) of the total combined voting
power of all classes of shares of stock of the Company or of any Subsidiary,
such Option shall not be exercisable after the expiration of five (5) years from
the date such Option is granted.

    6.3  EXERCISE OF AND PAYMENT FOR OPTIONS.  Options granted under the Plan
shall be exercisable at such times and be subject to such restrictions and
conditions as the Committee shall in each instance approve.

    A Participant may exercise an Option at any time during the Exercise Period.
Options shall be exercised by the delivery of a written notice of exercise to
the Company or its designee, setting forth the number of Shares with respect to
which the Option is to be exercised, accompanied by provisions for full payment
for the Shares.

    The Option Price upon exercise of any Option shall be payable either:
(a) in cash or its equivalent, (b) by tendering previously acquired Shares
having an aggregate Fair Market Value at the time of exercise

                                      A-5

equal to the total Option Price (provided that the Shares which are tendered
must have been held by the Participant for at least six (6) months prior to
their tender to satisfy the Option Price), (c) by share withholding, (d) by
cashless exercise or (e) by a combination of (a),(b),(c), and/or (d).

    As soon as practicable after receipt of a written notification of exercise
of an Option and provisions for full payment therefor, there shall be delivered
to the Participant, in the Participant's name, Share certificates in an
appropriate amount based upon the number of Shares purchased under the
Option(s).

    6.4  TERMINATION OF EMPLOYMENT.  Each Option Award Agreement shall set forth
the extent to which the Participant shall have the right to exercise the Option
following termination of the Participant's employment with the Company and its
Subsidiaries. Such provisions shall be determined in the sole discretion of the
Committee (subject to applicable law), shall be included in the Option Award
Agreement entered into with Participants, need not be uniform among all Options
granted pursuant to the Plan or among Participants and may reflect distinctions
based on the reasons for termination of employment. If the employment of a
Participant by the Company or by any Subsidiary is terminated for any reason
other than death, any Incentive Stock Option granted to such Participant may not
be exercised later than three (3) months (one (1) year in the case of
termination due to Disability) after the date of such termination of employment.

    6.5  TRANSFERABILITY OF OPTIONS.  Except as otherwise determined by the
Committee and set forth in the Option Award Agreement, no Option granted under
the Plan may be sold, transferred, pledged, assigned, or otherwise alienated or
hypothecated, other than by will or by the laws of descent and distribution, and
all Incentive Stock Options granted to a Participant under the Plan shall be
exercisable during his or her lifetime only by such Participant.

ARTICLE 7. STOCK APPRECIATION RIGHTS

Tandem SARs or any combination of these forms of SAR.

    The Committee shall have complete discretion in determining the number of
SARs granted to each Participant (subject to Article 4 herein) and, consistent
with the provisions of the Plan, in determining the terms and conditions
pertaining to such SARs.

    The Base Value of a Freestanding SAR shall equal the Fair Market Value of a
Share on the date of grant of the SAR. The Base Value of Tandem SARs shall equal
the Option Price of the related Option.

    7.2  SAR AWARD AGREEMENT.  Each SAR grant shall be evidenced by an SAR Award
Agreement that shall specify the number of SARs granted, the Base Value, the
term of the SAR, the Exercise Period and such other provisions as the Committee
shall determine.

    7.3  EXERCISE AND PAYMENT OF SARS.  Tandem SARs may be exercised for all or
part of the Shares subject to the related Option upon the surrender of the right
to exercise the equivalent portion of the related Option. A Tandem SAR may be
exercised only with respect to the Shares for which its related Option is then
exercisable.

    Notwithstanding any other provision of the Plan to the contrary, with
respect to a Tandem SAR granted in connection with an ISO: (i) the Tandem SAR
will expire no later than the expiration of the underlying ISO; (ii) the value
of the payout with respect to the Tandem SAR may be for no more than one hundred
percent (100%) of the difference between the Option Price of the underlying ISO
and the Fair Market Value of the Shares subject to the underlying ISO at the
time the Tandem SAR is exercised; and (iii) the Tandem SAR may be exercised only
when the Fair Market Value of the Shares subject to the ISO exceeds the Option
Price of the ISO.

                                      A-6

    Freestanding SARs may be exercised upon whatever terms and conditions the
Committee, in its sole discretion, imposes upon them.

Company, setting forth the number of SARs being exercised. Upon exercise of an
SAR, a Participant shall be entitled to receive payment from the Company in an
amount equal to the product of:

       exercise over (ii) the Base Value multiplied by

    (b) the number of Shares with respect to which the SAR is exercised.

    At the sole discretion of the Committee, the payment to the Participant upon
SAR exercise may be in cash, in Shares of equivalent value, or in some
combination thereof.

Subsidiaries. Such provisions shall be determined in the sole discretion of the
Committee, shall be included in the SAR Award Agreement entered into with
Participants, need not be uniform among all SARs granted pursuant to the Plan or
among Participants and may reflect distinctions based on the reasons for
termination of employment.

    7.5  TRANSFERABILITY OF SARS.  Except as otherwise determined by the
Committee and set forth in the SAR Award Agreement, no SAR granted under the
Plan may be sold, transferred, pledged, assigned, or otherwise alienated or

Participants holding Restricted Stock shall receive all regular cash dividends
paid with respect to all Shares while they are so held. All other distributions
paid with respect to such Restricted Stock shall be credited to Participants

Restricted Stock with respect to which such distributions were made.

evaluate and, where appropriate, replace the independent auditors or to nominate
in any proxy statement the independent auditors to be proposed for shareholder

        independent auditors and management, including the scope of the
        examination to be performed, the assistance to be provided by the
        internal auditors and any developments in accounting principles and
        auditing standards that may affect either the financial statements or
        the audit.

     5. Prior to release of the annual report to the stockholders, review and
        discuss the audited financial statements and the results of the audit
        with the independent auditors and management. Discuss matters required
        to be communicated to audit committees in accordance with Statement on
        Auditing Standards No. 61.

     6. Report to the Board on the scope and results of the annual audit,
        including a report prepared in accordance with Item 306 of Regulation
        S-K to be included in the Company's proxy statement, and from time to
        time report on other activities of the Committee and recommend to the
        Board such changes, additions or variations in the auditing, accounting
        and control functions as the Committee may deem desirable.

     7. Recommend to the Board whether the audited financial statements should
        be included in the Company's annual report on Form 10-K.

        between the independent auditors and the Company.

    10. Actively engage in a dialogue with the independent auditors with respect
        to any disclosed relationships or services that may impact the
        objectivity and independence of the independent auditors and recommend

        auditors' written statement to satisfy itself of the independent
        auditors' independence.

    11. With the independent auditors, management and the internal auditors,
        review and analyze periodically the Company's internal accounting
        control systems and related corporate policies and control systems,
