To Our Stockholders:

You are cordially invited to attend the Annual Meeting of Stockholders to be
held on Tuesday, April 22, 1997,28, 1998, at 11:00 A.M.a.m., Central Daylight Savings Time,
at 909 Airport Road, Bismarck, North Dakota 58504. The other directorsDirectors 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 Meeting and Proxy Statement. I would like to note for
your special attention that the Board of Directors has recommended to the owners
of Common Stock of the Company the approval of long-term incentive plans for
non-employee directors and for executives. These plans are designed to foster
and promote the success of the Company and its stockholders by making an equity
interest in the Company and a long-term approach essential elements of the
compensation of non-employee directors and executives. Under the plans, the
Board of Directors and the Compensation Committee will have the means to craft
proper incentives and rewards for non-employee directors and executives. Your
Company has recently acquired businesses which operate in highly competitive
markets. Additionally, its traditional utility markets have become deregulated
(natural gas) or soon will be deregulated (electricity). In the past your
Company has, from time to time, brought single component plans to you for
approval. This has been done as needed, with two, three, or more years passing
between each submittal. The changing competitive environment demands more
flexibility and quicker reaction times. The plans provide both.

The plans will serve as an organizational umbrella over the existing
single component incentive plans and will not duplicate those plans. Giving the
Board the flexibility to react to the changing environment will advance the
Company's interests by enhancing its ability to attract, retain and motivate, on
a long-term basis, outstanding individuals of the highest caliber, talent, and
experience to serve in key positions with the Company. The Board believes that
by aligning the interests of those in a position to make significant
contributions to the success of the Company with the interests of the
stockholders of the Company encourages and promotes the long-term growth and
success of the Company. In addition to the formal
issues, a brief report on current matters of interest will be presented.
Luncheon will be served following the meeting.

We were pleased with the response of our stockholders at the 19961997 Annual
Meeting at which 89.088.9 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 19971998 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.

You will notice that we have changed the format of the proxy from a proxy
card to a letter proxy. The new format is larger and is easier to read. It also
provides the convenience of voting your proxy by Touchtone telephone if you are
a stockholder of record. The instructions are on the letter proxy.
Representation of your shares at the meeting is very important and we
urge that,important. Accordingly,
whether or not you now plan to attend the meeting, we urge you to submit your proxy
promptly mark,
date, signby one of the two methods offered: (1) by marking, dating, signing, and
returnreturning the enclosed letter proxy card in the envelope provided, for that
purpose. Ifor (2) by
following the instructions and voting your proxy by Touchtone telephone by
calling the toll free telephone number on the proxy. In either event, 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/JohnSIGNATURE

1997 NON-EMPLOYEE DIRECTOR LONG-TERM INCENTIVE PLAN

At its meeting on February 6 1997, the Board of Directors adopted the
1997 Non-Employee Director Long-Term Incentive Plan (the "Director Plan"),
subject to ratification by the stockholders.

The Board of Directors believes that the Director Plan will help attract
qualified persons to serve as directors, increase the equity interests of
directors in the Company and strengthen the common interest of directors,
stockholders and customers. The Director Plan is also intended to provide
appropriate incentives and rewards to encourage directors to take a long-term
approach in the formulation of corporate policy and to encourage them to remain
on the Board.

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

PURPOSE OF THE DIRECTOR PLAN

The purpose of the Director Plan is to promote the success and enhance
the value of the Company by linking the personal interests of non-employee
directors to those of the Company's stockholders and customers. The Director
Plan is further intended to assist the Company in its ability to motivate,
attract and retain highly qualified individuals to serve as directors of the
Company.

EFFECTIVE DATE AND DURATION

The Director Plan will become effective upon ratification by the
stockholders, and shall remain in effect, subject to the right of the Board of
Directors to terminate the Director Plan at any time, until all shares subject
to the Director Plan shall have been purchased or acquired.

AMENDMENTS

The Board may, at any time and from time to time, alter, amend, suspend
or terminate the Director Plan in whole or in part.

ADMINISTRATION OF THE DIRECTOR PLAN

The Director Plan will be administered by a committee appointed by the
Board of Directors or by the Board of Directors (the "Committee").

SHARES SUBJECT TO THE DIRECTOR PLAN

The Director Plan authorizes the grant of up to 200,000 shares of MDU
Resources Group, Inc. Common Stock. 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 Company Common Stock as of December 31, 1996 was
$23.00.

-5-

If any corporate transaction occurs that causes a change in the
capitalization of the Company, the Committee shall make such adjustments to the
number and class of shares of stock delivered, and the number and class and/or
price of shares of Common Stock subject to outstanding awards made under the
Director Plan, as it deems appropriate and equitable to prevent dilution or
enlargement of participants' rights.

ELIGIBILITY AND PARTICIPATION

Only non-employee directors of the Company are eligible to participate in
the Director Plan. The number of directors who will be eligible initially to
participate under the Director Plan will be ten.

GRANTS UNDER THE DIRECTOR PLAN

STOCK OPTIONS. The Committee may grant nonqualified stock options under
the Director Plan. The exercise price for each such award shall be 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.

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 in a combination of the foregoing.

STOCK APPRECIATION RIGHTS. SARs granted under the Director Plan 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 price of the related option.

Freestanding SARs may be exercised upon such terms and conditions as are
imposed by the Committee and 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 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.

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 certain
specified conditions and the payment of shares in lieu of cash based on
performance criteria established by the Committee.

-6-

TERMINATION OF DIRECTOR STATUS

Each award agreement shall set forth the participant's rights with
respect to each award following termination of his position on the Board of
Directors.

TRANSFERABILITY

Except as otherwise determined by the Committee at the time of grant,
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 legal
representative during his or her lifetime.

CHANGE IN CONTROL

Upon a change in control, as defined below,

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

(b) Any restriction periods and restrictions imposed on restricted
stock shall be deemed to have expired 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.

For purposes of the above, 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; (v) the sale or other
disposition of all or substantially all of the assets of Montana-Dakota
Utilities Co., other than to a subsidiary of the Company; or (vi) any other
event which shall be deemed by a majority of the Committee to constitute a
"change in control".

AWARD INFORMATION

It is not possible at this time to determine awards that will be made
pursuant to the Director Plan.

FEDERAL INCOME TAX CONSEQUENCES

The following is a brief description of the federal tax consequences
related to options to be awarded under the Director Plan.

-7-

CONSEQUENCES TO THE OPTIONHOLDER

GRANT. There are no federal income tax consequences to the optionholder solely
by reason of the grant of an option under the Director Plan.

EXERCISE. Upon the exercise of an option, 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 as the exercise price.

The optionholder's tax basis in the shares acquired pursuant to the exercise of
an option will be the amount paid upon exercise plus the amount of ordinary
income recognized by the optionholder upon exercise.

DISPOSITION OF SHARES ACQUIRED UNDER AN OPTION. If an optionholder disposes of
shares of Company Common Stock acquired upon exercise of an option in a taxable
transaction, the optionholder will recognize capital gain or loss in an amount
equal to the difference between his basis (as discussed above) in the shares
sold and the total amount realized upon disposition. Any such capital gain or
loss will be 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.

CONSEQUENCES TO THE COMPANY

There are no federal income tax consequences to the Company by reason of the
grant of options.

At the time the optionholder recognizes ordinary income from the exercise of an
option, the Company will be entitled to a federal income tax deduction in the
amount of the ordinary income so recognized (as described above).

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 an
option.

OTHER TAX CONSEQUENCES

The foregoing discussion is not a complete description of the federal income tax
aspects of options under the Director Plan. 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. Approval of the
Director Plan requires the affirmative vote of the holders of a majority of the
Common Stock present or represented and entitled to vote. If a choice has been
specified by a stockholder by means of the ballot on 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.

1997 EXECUTIVE LONG-TERM INCENTIVE PLAN

At its meeting on February 6, 1997, the Board of Directors adopted the
1997 Executive Long-Term Incentive Plan (the "Executive Plan"), subject to
ratification by the stockholders.

The Board of Directors believes that the Executive Plan will help attract
qualified persons to serve as officers and key employees of the Company,
increase the equity interests of executives in the Company and strengthen the
common interest of executives, stockholders and customers. The Executive Plan is
also intended to provide appropriate incentives and rewards to encourage
executives to take a long-term approach in the formulation of corporate policy
and to encourage them to remain with the Company.

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

-8-

PURPOSE OF THE EXECUTIVE PLAN

The purpose of the Executive Plan 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 Executive
Plan 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 Executive Plan will become effective upon ratification by the
stockholders, and shall remain in effect, subject to the right of the Board of
Directors to terminate the Executive Plan at any time, until all shares subject
to the Executive Plan 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 Executive Plan in whole or in part, subject to certain
restrictions as stated therein.

ADMINISTRATION OF THE EXECUTIVE PLAN

The Executive Plan will be 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 EXECUTIVE PLAN

The Executive Plan authorizes the grant of up to 1,200,000 shares of MDU
Resources Group, Inc. Common Stock. 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 Company Common Stock as of December 31, 1996 was
$23.00.

If any corporate transaction occurs that causes a change in the
capitalization of the Company, the Committee shall make such adjustments to the
number and class of shares of stock delivered, and the number and class and/or
price of shares of Common Stock subject to outstanding awards made under the
Executive Plan, as it deems appropriate and equitable to prevent dilution or
enlargement of participants' rights.

ELIGIBILITY AND PARTICIPATION

Employees eligible to participate in the Executive Plan include all
officers and key employees of the Company and its subsidiaries, as determined by
the Committee, including employees who are members of the Board of Directors,
but excluding directors who are not employees. It is anticipated that the
approximate number of employees who will be eligible initially to participate
under the Executive Plan will be 31.

GRANTS UNDER THE EXECUTIVE PLAN

STOCK OPTIONS. The Committee may grant incentive stock options ("ISOs"),
nonqualified stock options ("NQSOs") or a combination thereof under the
Executive Plan. 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.

STOCK APPRECIATION RIGHTS. SARs granted under the Executive Plan may be

-10-

AWARD INFORMATION

It is not possible at this time to determine awards that will be made
pursuant to the Executive Plan.

FEDERAL INCOME TAX CONSEQUENCES

The following is a brief description of the federal tax consequences
related to options to be awarded under the Executive Plan.

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 Executive Plan.

EXERCISE. The exercise of an ISO is not a taxable event for regular federal
income tax purposes if certain requirements are satisfied, including the
restriction providing that the optionholder generally must exercise the option
no later than three (3) months following the termination of employment. However,
such exercise may give rise to an 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 as the
exercise price. The ordinary income 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 recognized by the optionholder upon exercise.

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 is
granted and more than one year after the date on which the shares are
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 the 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 is
granted or within one year after the transfer of shares to the optionholder
pursuant to the exercise of the ISO, then at the time of disposition the
optionholder will generally recognize ordinary income equal to the lesser of (i)
the excess of such share's fair market value on the date of exercise over the

-11-

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, then 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), then 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 his
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 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 imposed in addition
to, but only to the extent it exceeds, the optionholder's regular tax for the
taxable year. Generally, AMT is computed at the rate of 26% of the excess of a
taxpayer's alternative minimum taxable income ("AMTI") over the exemption
amount, but only if such excess amount does not exceed $175,000 ($87,500 in the
case of married individuals filing separate returns). The AMT tax rate is 28% of
such excess amount over the $175,000 ($87,500) amount. For these purposes, the
exemption amount is $45,000 for joint returns or returns of surviving spouses
($33,750 for single taxpayers and $22,500 for married individuals filing
separate returns), reduced by 25% of the excess AMTI over $150,000 for joint
returns or returns of surviving spouses ($112,500 for single taxpayers and
$75,000 for married individuals filing separate returns). A taxpayer's AMTI is
essentially the taxpayer's taxable income adjusted pursuant to the AMT
provisions and increased by items of tax preference.

The exercise of ISOs (but not NQSOs) will generally result in an upward
adjustment to the optionholder's AMTI in the year of exercise by an amount equal
to the excess, if any, of the fair market value of the stock on the date of
exercise over the exercise price. The basis of the stock acquired, for AMT
purposes, will equal the exercise price increased by the prior upward adjustment
of the taxpayer's AMTI due to the exercise of the option. This will result in a
corresponding downward adjustment to the optionholder's AMTI in the year the
stock is disposed of.

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 ISOs (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 withholding obligations described below. To the extent
the optionholder recognizes ordinary income by reason of a disqualifying
disposition of the stock acquired upon exercise of ISOs, 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 shares 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 ISOs and NQSOs under the Executive Plan. 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. Approval of
the Executive Plan requires the affirmative vote of the holders of a majority of
the Common Stock present or represented and entitled to vote. If a choice has
been specified by a stockholder by means of the ballot on 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 tableTable 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 pre-retirementpreretirement
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 Supplemental Income Security PlanSISP for senior management personnel. In 1996, 751997, 73 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.

COMPENSATION COMMITTEE REPORT ON EXECUTIVE COMPENSATION

INTRODUCTION

Decisions on compensation for the Company's executive officers are made by
the Compensation Committee of the Board of Directors. The Committee was created
in 1967 and has been and is composed entirely of non-employee directors.Directors. In the
late part of each calendar year, the Committee reviews and approves, with any
modifications it deems appropriate, the Executive Compensation Policy for the
executive officers including the Chief Executive Officer. The approved plan is
implemented the following calendar year.

EXECUTIVE COMPENSATION POLICY

The Executive Compensation Policy is designed to attract and retain
qualified executive officers, to recognize above-average job performance, and to
provide a direct and strong link between Company performance and executive pay.
The Board of Directors in 1994 adopted Stock Ownership Guidelines under which
executives are required to own Company Common Stock valued from two times their
annual salary to four times their annual salary (in the case of the Chief
Executive Officer). Total compensation is intended to be competitive with that paid by comparable

-14-

companies in the regulated electric and gas utility industry, relevant segments
of the energy and mining industries, and companies from general industry. There
are fourthree components of total executive compensation: (1) Base salary;
(2) Management Incentive Compensation Plan;
(3) 1992 Key Employee Stock Option Plan; and
(4) Restricted Stock Bonus Plan.

As indicated above, the base salary, componentannual
incentive compensation, and long-term incentive compensation.

For 1997, compensation paid to the Company's executive officers qualified as
fully deductible under federal tax laws. The Committee continues to review the
impact of compensation is designed
to be competitive with that paid by comparable companies. An external consultant
reviews comparative surveysfederal tax laws, including Edison Electric Institute Executive
Compensation Survey, American Gas Association Top Management Survey, KPMG Peat
Marwick LLP Oil and Gas Compensation Survey, PAS Inc. Executive Compensation
Survey for Contractors, Towers Perrin Executive Compensation DataBank, and
Executive Compensation Services Top Management Report. WhileSection 162(m) of the companies used
in these surveys are not the same as the peer group of companies used in the
Performance Graph, the Compensation Committee believes these surveys provide a
broader base of data and are commonly used to set executive salaries. The Edison
Electric Institute Executive Compensation Survey is a 1995 survey prepared by
Edison Electric Institute and includes nearly 100 participants of diverse size,
comprised of electric or electric/gas utility companies, utility parent
companies or diversified parent companies. The American Gas Association Top
Management Survey is a 1995 survey of salary for 87 natural gas
companies-distribution, transmission, combination (gas and electric) and
integrated. The KPMG Survey includes 123 participants from the oil and gas
industry and the PAS Survey for Contractors has over 250 participants. The
Towers Perrin Executive Compensation DataBank is a 1995 survey of over 425
companies representing a variety of industries and revenue levels; and the
Executive Compensation Services Top Management Report is a 1995-96 survey ofInternal Revenue
Code, on executive compensation, for 1,270 companies cutting across all major industry
lines. The consultant used these two surveys, including data representative of
the companies' revenue levels, for a general industry comparison. The external
data from all these surveys is used to develop a market-consensus salary for
each executive position. "Market-consensus salary" represents the market value
for each position based upon the above referenced surveys. For executive
officers the consensus reflects a 50 percent weighting of general industry data
and a 50 percent weighting of utility industry data. The Compensation Committee
sets a targeted range of compensation from 80%-115% around the market-consensus
salary. The Compensation Committee uses this targeted range together with an
analysis of the value of the executive position and individual evaluation to
establish base salaries for executive officers. In the case of the Chief
Executive Officer, the same methodology is used and, in addition, the Committee
takes into consideration salary information from the peer group of companies in
the Performance Graph.

All executive officers are eligible for awards under the Company's
various incentive plans referred to above. The Compensation Committee believes
that offering incentives to executive officers will enhance the long-term
performance of the Company, promote cost efficiency and further overall
stockholder returns. The Committee uses these plans as it deems appropriate to
achieve these goals. The Compensation Committee determines awards pursuant to
these plans based generally on what it believes other similar companies are
doing.

The Companybut has not formulated any policy with regard
thereto.

The Board of Directors in 1993 adopted Stock Ownership Guidelines, under
which executives are required to own Company Common Stock valued from one times
their annual salary to four times their annual salary (in the deductibility of qualifying compensation paid to executive officers under
Section 162(m)case of the Internal Revenue Code.

Executive Officer).

BASE SALARY

Base salaries are reviewed annually for all employees of the Company,
including executive officers. The Compensation Committee uses data from a number
of comparative compensation surveys provided by an external consultant to
develop a market consensus salary for each executive position. The surveys
reflect a larger and more diversified group of companies than companies included
in 1996the peer group in the graph following this report. The Committee also
examined data from the peer group of companies.

The market consensus salary, which is based upon general industry data,
utility industry data, and peer group data, represents the perceived market
value of each position. Base salaries are then set by the Compensation
Committee, which considers (i) a targeted range of compensation around the
market consensus salary (80% - 115% for 1997), (ii) the executive's current
salary in comparison to the targeted range, and (iii) individual performance. No
formal weighting was comprisedgiven to any of these criteria. In 1997, base salary, cash awards under the Management Incentive
Compensation Plan and dividend equivalents accruing on option grants made
previously under the 1992 Key Employee Stock Option Plan.

Base salary
increases for the eight executive officers during 1996 ranged from 0%
to 10.96% and averaged 4.87%6.57%. Salary increases were a function of (1) the
Compensation Committee's assessment of the individual performance of each
executive and (2) the current salary of each executive compared to that paid by
comparable companies as determined by the external consultant (as discussed
above). A more favorable performance appraisal permitted a larger increase. If
the current salary lagged that paid by comparable companies, a larger increase
was permitted. TheTheir base salaries
during 1996 averaged 82.02%94.3% of the
market-consensus salary for the Company's executive positions. Fortheir market consensus salaries. Mr. Mellen, the Chief
Executive Officer, the consultant used the surveys described above and
considered the salary information from the peer group of companies in the
Performance Graph to determine the Chief Executive Officer market-consensus
salary. The base salary of Mr. Mellenreceived a 4.8% increase effective for the year 1996 reflected an increase of
10.96% over his 1995 base salary. The Committee determined Mr. Mellen's increase

-15-

through consideration ofbeginning
July 1, 1997, based upon the survey data discussed above the Company's overall
financial performance in 1996criteria and Mr. Mellen's individual performance including
his personal role in
achieving 19961997 corporate performance. The Committee also
consideredperformance, his development of a succession plan, and
the successful acquisitions made during the year. During 1997, approximately
55.9% of Mr. Mellen's leadership in positioningcompensation was

base pay. The remainder was performance based. This reflects the Company for the futureCommittee's
belief in the rapidly-changing regulatory environment. The Committee did not give formal
weightingimportance of having substantial at-risk compensation to provide a
direct and strong link between Company performance and executive pay.

ANNUAL INCENTIVE COMPENSATION

Annual incentive compensation is determined under the criteria used in order to set salary increases for the
executive officers or for the Chief Executive Officer.

The Management Incentive
Compensation Plan is structured so that cash
incentive awards reflect the attainment of specific annual levels of
performance.Plan. The performance measures used reflect both the stockholders'
interest (earnings) and the customers' interest (cost efficiency). Additionally,
individual performance is evaluated and appropriate adjustments to target award
levels may be made.made, although there is no formal weighting of corporate and
individual performance. Target award levels are set at a percentage of each
participant's assigned salary grade midpoint. The percentage for the Chief Executive Officer
was 35% and for the other executive officers ranged from 20% to 30%. A target
incentive fund is developed at the beginning of each plan year based upon the
aggregate target award levels of all participants. The size of the fund will
increase or decrease based uponmidpoint, with actual Company performance in relation to the
pre-established goals. Individual awards will be greater or lesser than target
amounts based upon an assessment of individual performance. Awards can rangeranging from 0% (less than 90% of budgeted earnings per share) to 150% (more than 108%
of budgeted earnings per share)
of the target amount. The annual corporate
performance targets for 1996 wereFor 1997, eight executive officers received an average of
145.9%, based on the degree of(i) achievement of 105% of
budgeted earnings. As a result of actualcorporate earnings exceeding thresholdat or near the maximum
level of performance and (ii) individual performance goals being met, cash awards were made
under the plan for the year 1996 to nine executive officers in the aggregate
amount of $675,673. The Chief Executive Officerperformance. Mr. Mellen received

1996. This amount was a payout of$186,450 or 150% of the targeted award, based on the
Company's actual earnings exceeding the threshold level of performance and upon
individual performance.amount.

LONG-TERM INCENTIVE COMPENSATION

The 1992 Key Employee Stock Option Plan, isthe Restricted Stock Bonus Plan,
and the 1997 Executive Long-Term Incentive Plan, approved by the stockholders at
last year's annual meeting, are the plans pursuant to motivate executives to
achieve specifiedwhich the Compensation
Committee may grant opportunities for long-term performance goalsincentive compensation. This
type of the Company and to encourage
ownership by them of the Common Stock of the Company. Itcompensation is designed to reinforce financial and strategic corporate
objectives, to emphasize pay for performance, and to focus executive effortexecutives on
long-term sustainable value creation. This
aligns the interests of the executivesOptions with those of the stockholder. The plan
consists of two elements: stock option grants and dividend equivalents.

Since optionsa three-year performance
cycle (1995-97) and related dividend equivalents were granted in 1995 andunder the three year performance cycle (1995-97) is still running, the Compensation
Committee determined that it was not necessary to grant further awards in 1996
to achieve the goals stated above.

The Restricted Stock Bonus Plan provides for awards of restricted stock
to individuals when designated by the Compensation Committee as having
demonstrated superior individual performance. The awards serve as a motivator
for long-term performance and as a retention device for individuals who have
demonstrated superior performance. The executive has a stake in the Company's
financial performance. Again, this aligns the interest of the executives with
those of the stockholders. No awards were made under this plan during 1996.

49.5% of the Chief Executive Officer's total compensation during 1996 was
based on objective annual performance criteria (through the Management Incentive
Compensation Plan) or long-term performance criteria (through the 1992 Key
Employee Stock
Option Plan reflectingin 1995. Performance goals established by the Committee and
described in the 1996 Proxy Statement for the 1995-97 performance cycle were
exceeded; therefore, exercisability of the options was accelerated and dividend
equivalents accrued on the
1995 option grants)were earned at 149%. An average of 40.1% of the total compensation of theNo options or other executive officers was based on objective annual performance criteria (through
the Management Incentive Compensation Plan) or long-term performance criteria
(through the 1992 Key Employee Stock Option Plan, reflecting the dividend
equivalents accrued on the 1995 option grants). The Committee believes that
having 49.5% of the compensation of the Chief Executive Officer and an average
of 40.1% of the compensation of other executive officers at risk provides a
direct and strong link between Company performance and executive pay.grants were made
in 1997.

DIRECTORS' COMPENSATION

Each Director who is not an officer of the Company (except the Chairman of
the Board) receives $13,000 and 300 shares of Company Common Stock as an annual
retainer for Board service. The Chairman receives $52,000 and 300 shares of
Company Common Stock. Audit and Compensation Committee Chairmen each receive a
$2,500 annual retainer, and Finance and Nominating Committee Chairmen each
receive a $1,000 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 $1000$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 an option award on June 3, 1997, of 1,500 shares of
Company Common Stock. The option award vested immediately and is exercisable for
10 years from the date of grant. The option price was $24.5625, the fair market
value of the stock on the date of the grant.

11
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 annual compensation in an
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.

-17-

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.

Restricted Stock in the Company's possession until such time as all restrictions
applicable to such Shares have been satisfied.

8.5 REMOVAL OF RESTRICTIONS. Restricted Stock shall become freely

Agreement shall set forth the extent to which the Participant shall have the
right to receive unvested Restricted Stock following termination of the
