Common Stock

Each person, other than the Non-Executive Chair of the Board, who is a Director
of the Company at any time during the calendar year shall receive a $125,000
stock payment, and any person who is the Non-Executive Chair of the Board shall
receive a $150,000 stock payment, on or about the Wednesday following the Board
of Directors’ regularly-scheduled November meeting, pursuant to the Non-Employee
Director Long-Term Incentive Compensation Plan. The stock payment shall be made
under the Non-Employee Director Long-Term Incentive Compensation Plan. The stock
payment shall be made by providing the Director or Non-Executive Chair with the
number of whole shares of Common Stock determined (i) if the shares are original
issue or treasury stock, by dividing the amount of the applicable stock payment
by the closing price of the Common Stock on the New York Stock Exchange on the
grant date and (ii) if the shares are purchased on the open market, by dividing
the amount of the applicable stock payment by the weighted average price paid to
purchase shares for the Director or Non-Executive Chair for that stock payment,
excluding any related brokerage commissions or other service fees. Any
fractional shares shall be paid in cash. The stock payment shall be prorated for
any Director or Non-Executive Chair who does not serve the entire calendar year
by multiplying the applicable stock payment by a fraction, the numerator of
which is the number of actual or expected months (with a partial month counted
as a full month) of service on the Board during the calendar year and the
denominator of which is twelve.

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

By written election a Director may reduce his or her annual cash retainers and
have that amount applied to the purchase of additional shares of Common Stock
under the Non-Employee Director Long-Term Incentive Compensation Plan. The
annual election shall specify the percentage of the annual cash retainers to be
applied toward the purchase of additional shares and must be received by the
Company by the last business day of the year prior to the year in which the
election is to be effective. No election may be changed or revoked for the
current year, but may be changed for a subsequent year. The additional stock
payments will be made on the last business day of March, June, September, and
December. The stock payment shall be made by providing the Director with the
number of whole shares of Common Stock determined (i) if the shares are original
issue or treasury stock, by dividing the amount of the applicable stock payment
by the closing price of the Common Stock on the New York Stock Exchange on the
grant date or (ii) if the shares are purchased on the open market, by dividing
the amount of the applicable stock payment by the weighted average price paid to
purchase shares for the Director for that stock payment, excluding any related
brokerage commissions or other service fees. No fractional shares shall be
purchased and cash in lieu of any fractional shares shall be paid to the
Director.

Travel Expense Reimbursement

All Directors will be reimbursed for reasonable travel expenses incurred while
serving as a Director, including spouse’s expenses, in connection with
attendance at meetings of the Company’s Board of Directors and its committees.
If the travel expense is related to the reimbursement of airfare, such
reimbursement will not exceed full-coach rate. Spousal travel expenses paid by
the Company are treated as taxable income to the Director. See the paragraph
below entitled "Code Section 409A" for further rules relating to travel expense
reimbursements.

Directors' Liability

Article Seventeenth of the Company's Restated Certificate of Incorporation
provides that no Director of the Company shall be liable to the Company or its
stockholders for breach of fiduciary duty as a Director, with certain exceptions
stated below. Section 7.07 of the Company's Bylaws requires the Company to
indemnify fully a Director against expenses, attorneys fees, judgments, fines
and amounts paid in settlement of any suit, action or proceeding, whether civil
or criminal, arising from an action of a Director by reason of the fact that the
Director was a Director of MDU Resources Group, Inc.

There are exceptions to the protections under Article Seventeenth of the
Company’s Restated Certificate of Incorporation: breaches of the Directors' duty
of loyalty to the Company or its stockholders, acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of the law,
violation of Section 174 of the Delaware General Corporation Law (relating to
unlawful declaration of dividends and unlawful purchase of the Company's stock),
and transactions from which the Director derived an improper personal benefit
(including short-swing profits under Section 16(b) of the Securities Exchange
Act of 1934).

Additional protection is provided through individual indemnification agreements
with each Director.

The Company has and does maintain Directors' and Officers' liability insurance
coverage with a 130 million limit.

Insurance Coverages

The Company maintains the following insurance for protection of its Directors as
they carry out the business of MDU Resources Group, Inc., which shall be
provided while serving as a Director:

1.    General liability and automobile liability insurance:

If driving a personal vehicle, the Directors are afforded automobile liability
coverage excess of their own personal automobile insurance under a combination
of policies with program limits to $125 million after a self-insured retention
of $500,000. If driving a vehicle owned by the Company, personal automobile
insurance does not apply.

For general liability, coverage is provided to Directors under a combination of
policies with program limits to $125 million after a self-insured retention of
$500,000.

2.
Fiduciary and crime insurance:

The Directors are afforded coverage under the fiduciary and crime liability
insurance policies. The fiduciary policy has a limit of $35 million and the
crime policy has a limit of $10 million.

3.    Aircraft liability insurance:

The Company's existing aircraft liability insurance extends coverage while a
hired, non-owned* aircraft is used by a Director in traveling to and from
Director or Board committee meetings. This insurance coverage is excess of any
underlying policy that may exist and provides limits of $200 million.

*Non-owned aircraft is defined as: 1) any aircraft registered under a “standard”
airworthiness certificate issued by the FAA; 2) aircraft with a seating capacity
not exceeding 40 seats; 3) aircraft that are not owned by MDU Resources Group,
Inc. or any of its subsidiaries; 4) aircraft that are not partly or wholly owned
by or registered in the Director’s name or the name of any Director’s household
member.

4.    Business travel accident insurance:

All Directors are protected by a group insurance policy with coverage of
$250,000 that provides 24-hour accident protection while traveling on Company
business.

Coverage in all instances begins at the actual start of a business trip and ends
when the Director returns to his/her home or regular place of employment.

The beneficiary of the insurance will be that beneficiary recorded on a
beneficiary designation provided by the Company.

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

5.    Group life insurance:

All outside Directors are protected by a non-contributory group life insurance
policy with coverage of $100,000.

The coverage begins the day the Director is elected to the Board of Directors
and terminates when the Director ceases to be an outside Director.

A Summary Plan Description (SPD) can be provided to the Director. The
beneficiary of the insurance will be the beneficiary recorded on a beneficiary
designation provided by the Company.

This protection is considered taxable compensation under current tax laws.
Consequently, the Company will provide each Director annually on Form 1099 the
amount of taxable income related to this coverage.

Hedging Stock Ownership
Directors are not permitted to hedge their ownership of Company common stock.
Hedging strategies include but are not limited to zero-cost collars, equity
swaps, straddles, prepaid variable forward contracts, security futures
contracts, exchange funds, forward sale contracts and other financial
transactions that allow the Director to benefit from devaluation of the
Company's stock. Hedging strategies may allow Directors to own stock technically
but without the full benefits and risks of such ownership. Therefore, Directors
are prohibited from engaging in any such transactions.

Policy Regarding Margin Accounts and Pledging of Company Stock
Effective December 21, 2012, Directors and related persons are prohibited from
holding Company common stock in a margin account or pledging Company securities
as collateral for a loan, with certain exceptions. Company common stock may be
held in a margin brokerage account only if the stock is explicitly excluded from
any margin, pledge or security provisions of the customer agreement. Company
common stock may be held in a cash account, which is a brokerage account that
does not allow any extension of credit on securities. “Related person” means a
Director’s spouse, minor child and any person (other than a tenant or domestic
employee) sharing the household of a Director, as well as any entities over
which a Director exercises control.

Code Section 409A

To the extent any reimbursements or in-kind benefits provided to a Director
pursuant to this policy constitute “deferred compensation” under Internal
Revenue Code Section 409A, any such reimbursement or in-kind benefit shall be
paid in a manner consistent with Treasury Regulation Section 1.409A-3(i)(1)(iv),
including the requirements that the amount of reimbursable expenses or in-kind
benefits provided during a year may not affect the expenses eligible for
reimbursement or in-kind benefits provided in any other year and that any
reimbursement be made on or before the last day of the calendar year following
the calendar year in which the expense was incurred.
