                                  RISK FACTORS

         In considering whether to purchase any of the securities being offered,
you should carefully consider all the information we have included or
incorporated by reference in this prospectus. In particular, you should
carefully consider the risk factors described below."

ECONOMIC RISKS

         THE RECENT EVENTS LEADING TO THE CURRENT ADVERSE ECONOMIC ENVIRONMENT
MAY HAVE A GENERAL NEGATIVE IMPACT ON OUR FUTURE REVENUES AND MAY RESULT IN A
GOODWILL IMPAIRMENT FOR INNOVATUM, INC., OUR INDIRECT WHOLLY OWNED SUBSIDIARY.

         In response to the occurrence of several recent events, including the
September 11, 2001 terrorist attack on the United States, the ongoing war
against terrorism by the United States and the bankruptcy of several large
energy and telecommunications companies and other large enterprises, the
financial markets have been highly volatile. An adverse economy could negatively
affect the level of governmental expenditures on public projects and the timing
of these projects which, in turn, would negatively affect the demand for our
products and services.

         Innovatum, Inc., our indirect wholly owned subsidiary that specializes
in cable and pipeline magnetization and locating, is subject to the economic
conditions within the telecommunications and energy industries. Innovatum could
face a future goodwill impairment if there is a continued downturn in these
sectors. At March 31, 2003, the goodwill amount at Innovatum was approximately
$8.3 million. The determination of whether an impairment will occur is dependent
on a number of factors, including the level of spending in the
telecommunications and energy industries, the rapid changes in technology,
competitors and potential new customers.

         WE RELY ON FINANCING SOURCES AND CAPITAL MARKETS. OUR INABILITY TO
ACCESS FINANCING MAY IMPAIR OUR ABILITY TO EXECUTE OUR BUSINESS PLANS, MAKE
CAPITAL EXPENDITURES OR PURSUE ACQUISITIONS THAT WE MAY OTHERWISE RELY ON FOR
FUTURE GROWTH.

         We rely on access to both short-term borrowings, including the issuance
of commercial paper, and long-term capital markets as a source of liquidity for
capital requirements not satisfied by the cash flow from operations. If we are
not able to access capital at competitive rates, the ability to implement our
business plans may be adversely affected. Market disruptions or a downgrade of
our credit ratings may increase the cost of borrowing or adversely affect our
ability to access one or more financial markets. Such disruptions could include:

     o    A severe economic downturn
     o    The bankruptcy of unrelated companies in the same line of business
     o    Capital market conditions generally
     o    Volatility in commodity prices
     o    Terrorist attacks
     o    Global events

         OUR NATURAL GAS AND OIL PRODUCTION BUSINESS IS DEPENDENT ON FACTORS
INCLUDING COMMODITY PRICES WHICH CANNOT BE PREDICTED OR CONTROLLED.

         These factors include: price fluctuations in natural gas and crude oil
prices; availability of economic supplies of natural gas; drilling successes in
natural gas and oil operations; the ability to contract for or to secure
necessary drilling rig contracts and to retain employees to drill for and
develop reserves; the ability to acquire natural gas and oil properties; and
other risks incidental to the operations of natural gas and oil wells.

ENVIRONMENTAL AND REGULATORY RISKS

         SOME OF OUR OPERATIONS ARE SUBJECT TO EXTENSIVE ENVIRONMENTAL LAWS AND
REGULATIONS THAT MAY INCREASE OUR COSTS OF OPERATIONS, IMPACT OR LIMIT OUR


                                       3



BUSINESS PLANS, OR EXPOSE US TO ENVIRONMENTAL LIABILITIES. ONE OF OUR
SUBSIDIARIES HAS BEEN SUED IN CONNECTION WITH ITS COALBED NATURAL GAS
DEVELOPMENT ACTIVITIES.

         We are subject to extensive environmental laws and regulations
affecting many aspects of our present and future operations including air
quality, water quality, waste management and other environmental considerations.
These laws and regulations can result in increased capital, operating, and other
costs, as a result of compliance, remediation, containment and monitoring
obligations, particularly with regard to laws relating to power plant emissions
and coalbed natural gas development. These laws and regulations generally
require us to obtain and comply with a wide variety of environmental licenses,
permits, inspections and other approvals. Both public officials and private
individuals may seek to enforce applicable environmental laws and regulations.
We cannot predict the outcome (financial or operational) of any related
litigation that may arise.

         Existing environmental regulations may be revised and new regulations
seeking to protect the environment may be adopted or become applicable to us.
Revised or additional regulations which result in increased compliance costs or
additional operating restrictions, particularly if those costs are not fully
recoverable from customers, could have a material affect on our results of
operations.

         Fidelity Exploration and Production Company, our indirect wholly owned
subsidiary, has been named as a defendant in several lawsuits filed in
connection with its coalbed natural gas development in the Powder River Basin in
Montana and Wyoming. If the plaintiffs are successful in these lawsuits, the
ultimate outcome of the actions could have a material effect on Fidelity's
future development of its coalbed natural gas properties.

         WE ARE SUBJECT TO EXTENSIVE GOVERNMENT REGULATIONS THAT MAY HAVE A
NEGATIVE IMPACT ON OUR BUSINESS AND OUR RESULTS OF OPERATIONS.

         We are subject to regulation by federal, state and local regulatory
agencies with respect to, among other things, allowed rates of return,
financings, industry rate structures, and recovery of purchased power and
purchased gas costs. These governmental regulations significantly influence our
operating environment and may affect our ability to recover costs from our
customers. We are unable to predict the impact on operating results from the
future regulatory activities of any of these agencies.

         Changes in regulations or the imposition of additional regulations
could have an adverse impact on our results of operations.

RISKS RELATING TO OUR INDEPENDENT POWER PRODUCTION BUSINESS

         THERE ARE RISKS INVOLVED WITH THE GROWTH STRATEGIES OF OUR INDEPENDENT
POWER PRODUCTION BUSINESS. IF WE ARE UNABLE TO ENTER INTO A CONTRACT WITH A
PURCHASER FOR THE POWER TO BE GENERATED FROM OUR PROPOSED 113-MEGAWATT
COAL-FIRED ELECTRIC GENERATION STATION IN MONTANA WE MAY NOT COMPLETE
CONSTRUCTION OR COMMENCE OPERATION OF THAT FACILITY, WHICH MAY RESULT IN AN
ASSET IMPAIRMENT.

         The operation of power generation facilities involves many risks,
including start up risks, breakdown or failure of equipment, competition,
inability to obtain required governmental permits and approvals and inability to
negotiate acceptable acquisition, construction, fuel supply or other material
agreements, as well as the risk of performance below expected levels of output
or efficiency.

         Our plans to construct a 113-megawatt coal-fired electric generation
station in Montana are pending. We purchased plant equipment and obtained all
permits necessary to begin construction. NorthWestern Energy terminated the
power purchase agreement for the energy from this plant in July 2002; however,
we are pursuing other markets for the energy and we are studying our options
regarding this project. We have suspended construction activities except for
those items of a critical nature. At March 31, 2003, our investment in this
project was approximately $27.5 million. If it is not economically feasible for
us to construct and operate this facility or if alternate markets cannot be
identified, an asset impairment may occur.


                                       4



RISKS RELATING TO FOREIGN OPERATIONS

         THE VALUE OF OUR INVESTMENT IN FOREIGN OPERATIONS MAY DIMINISH DUE TO
POLITICAL, REGULATORY AND ECONOMIC CONDITIONS AND CHANGES IN CURRENCY EXCHANGE
RATES IN COUNTRIES WHERE WE DO BUSINESS.

         We are subject to political, regulatory and economic conditions and
changes in currency exchange rates in foreign countries where we do business.
Significant changes in the political, regulatory or economic environment in
these countries could negatively affect the value of our investments located in
these countries. Also, since we are unable to predict the fluctuations in the
foreign currency exchange rates, these fluctuations may have an adverse impact
on our results of operations.

         Our 49 percent equity investment in a 220-megawatt natural gas-fired
electric generation project in Brazil includes a power purchase agreement that
contains an embedded derivative. This embedded derivative derives its value from
an annual adjustment factor that largely indexes the contract capacity payments
to the U.S. dollar. In addition, from time to time, other derivative instruments
may be utilized. The valuation of these financial instruments, including the
embedded derivative, can involve judgments, uncertainties and the use of
estimates. As a result, changes in the underlying assumptions could affect the
reported fair value of these instruments. These instruments could recognize
financial losses as a result of volatility in the underlying fair values, or if
a counterparty fails to perform.

OTHER RISKS

         COMPETITION IS INCREASING IN ALL OF OUR BUSINESSES.

         All of our business segments are subject to increased competition. The
independent power industry includes numerous strong and capable competitors,
many of which have greater resources and more experience in the operation,
acquisition and development of power generation facilities. Utility services
competition is based primarily on price and reputation for quality, safety and
reliability. The construction materials products are marketed under highly
competitive conditions and are subject to such competitive forces as price,
service, delivery time and proximity to the customer. The electric utility and
natural gas industries are also experiencing increased competitive pressures as
a result of consumer demands, technological advances, deregulation, greater
availability of natural gas-fired generation and other factors. Pipeline and
energy services competes with several pipelines for access to natural gas
supplies and gathering, transportation and storage business. The natural gas and
oil production business is subject to competition in the acquisition and
development of natural gas and oil properties.

         WEATHER CONDITIONS CAN ADVERSELY AFFECT OUR OPERATIONS AND REVENUES.

         Our results of operations can be affected by changes in the weather.
Weather conditions directly influence the demand for electricity and natural
gas, affect the price of energy commodities and affect the ability to perform
services at the utility services and construction materials and mining
businesses. In addition, severe weather can be destructive, causing outages
and/or property damage, which could require additional costs to be incurred. As
a result, adverse weather conditions could negatively affect our results of
operations and financial conditions.

         OUR FINANCIAL RESULTS MAY BE IMPACTED BY THE IMPORTANT FACTORS
DESCRIBED BELOW.

        Following are some specific factors that you should consider for a
better understanding of our financial condition. These factors are important
factors that may impact our financial results in future periods.

     o    Acquisition and disposal of assets or facilities
     o    Changes in operation and construction of plant facilities
     o    Changes in present or prospective generation
     o    Changes in anticipated tourism levels
     o    The availability of economic expansion or development opportunities
     o    Population growth rates and demographic patterns
     o    Market demand for energy from plants or facilities
     o    Changes in tax rates or policies


                                       5



     o    Unanticipated project delays or changes in project costs
     o    Unanticipated changes in operating expenses or capital expenditures
     o    Labor negotiations or disputes
     o    Inflation rates
     o    Inability of various counterparties to meet their contractual
          obligations
     o    Changes in accounting principles and/or the application of such
          principles to us
     o    Changes in technology and legal proceedings
     o    The ability to effectively integrate the operations of acquired
          companies

                           FORWARD-LOOKING STATEMENTS

       We are including these cautionary statements in this prospectus to make
applicable and to take advantage of the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995 for any forward-looking statements made
by us, or on our behalf. Forward-looking statements include statements
concerning plans, objectives, goals, strategies, future events or performance,
and underlying assumptions (many of which are based, in turn, upon further
assumptions) and other statements which are other than statements of historical
facts. From time to time, we may publish or otherwise make available
forward-looking statements of this nature. All these subsequent forward-looking
statements, whether written or oral and whether made by us or on our behalf, are
also expressly qualified by these cautionary statements.

       Forward-looking statements involve risks and uncertainties, which could
cause actual results or outcomes to differ materially from those expressed. Our
expectations, beliefs and projections are expressed in good faith and are
believed by us to have a reasonable basis, including without limitation
management's examination of historical operating trends, data contained in our
records and other data available from third parties. Nonetheless, our
expectations, beliefs or projections may not be achieved or accomplished.

       Any forward-looking statement contained in this document or any document
incorporated by reference into this document speaks only as of the date on which
the statement is made, and we undertake no obligation to update any
forward-looking statement or statements to reflect events or circumstances that
occur after the date on which the statement is made or to reflect the occurrence
of unanticipated events. New factors emerge from time to time, and it is not
possible for management to predict all of the factors, nor can it assess the
effect of each factor on our business or the extent to which any factor, or
combination of factors, may cause actual results to differ materially from those
contained in any forward-looking statement.

        Following are some specific factors that should be considered for a
better understanding of our financial condition. These factors are important
factors that could cause our actual results or outcomes to differ materially
from those discussed in the forward-looking statements included elsewhere in
this prospectus.

     o    Population growth rates and demographic patterns
     o    Market demand for energy from plants or facilities
     o    Changes in tax rates or policies
     o    Unanticipated project delays or changes in project costs
     o    Unanticipated changes in operating expenses or capital expenditures
     o    Labor negotiations or disputes

         Our consolidated financial statements for the year ended December 31,
2001, incorporated into this document by reference were audited by Arthur
Andersen LLP. After reasonable efforts, we have not been able to obtain Arthur
Andersen LLP's consent to the incorporation by reference of its audit report
dated January 23, 2002 into the registration statement of which this prospectus
is a part. Rule 437a under the Securities Act of 1933 permits us to file the
registration statement and this prospectus without Arthur Andersen LLP's written
consent, but as a result of the lack of Arthur Andersen LLP's consent, you will
not be able to sue Arthur Andersen LLP pursuant to Section 11(a)(4) of the
Securities Act of 1933 and your right of recovery under that section may be
limited.

         Upon the recommendations of the audit committee, our Board of
Directors, in February 2002, approved the dismissal of Arthur Andersen LLP as
our independent public accountants following the 2001 audit and, in March 2002,
approved the selection of Deloitte & Touche LLP as independent public
accountants for the 2002 fiscal year.

(1)      On January 1, 2003, we adopted Statement of Financial Accounting
         Standards (SFAS) No. 143, "Accounting for Asset Retirement
         Obligations." SFAS No. 143 requires entities to record the fair value
         of a liability for an asset retirement obligation in the period in
         which it is incurred. When the liability is initially recorded, the
         entity capitalizes a cost by increasing the carrying amount of the
         related long-lived asset. Over time, the liability is accreted to its
         present value each period, and the capitalized cost is depreciated over


                                       9



         the useful life of the related asset. Upon settlement of the liability,
         an entity either settles the obligation for the recorded amount or
         incurs a gain or loss upon settlement.

         Upon adoption of SFAS No. 143, we recorded obligations related to the
         plugging and abandonment of natural gas and oil wells; decommissioning
         of certain electric generating facilities; reclamation of certain
         aggregate properties and certain other obligations associated with
         leased properties. Removal costs associated with certain natural gas
         distribution, transmission, storage and gathering facilities have not
         been recognized as these facilities have been determined to have
         indeterminate useful lives.

         In addition, upon adoption of SFAS No. 143, we recorded an additional
         discounted liability of $22.5 million and a regulatory asset of
         $493,000, increased net property, plant and equipment by $9.6 million
         and recognized a one-time cumulative effect charge of $7.6 million (net
         of deferred income tax benefits of $4.8 million). We believe that any
         expenses under SFAS No. 143 as they relate to regulated operations will
         be recovered in rates over time and accordingly, deferred such expenses
         as a regulatory asset upon adoption. We will continue to defer those
         SFAS No. 143 expenses that we believe will be recovered in rates over
         time. In addition to the $22.5 million liability recorded upon the
         adoption of SFAS No. 143, we had previously recorded a $7.5 million
         liability related to retirement obligations.

         If SFAS No. 143 had been in effect during 2002 and 2001, our liability
         would have been approximately $27.0 million and $31.4 million at
         January 1, 2002 and January 1, 2001, respectively, including previously
         recorded liabilities of $6.1 million and $15.1 million related to
         retirement obligations at January 1, 2002 and January 1, 2001,
         respectively.





                       DESCRIPTION OF THE DEBT SECURITIES

         The following description sets forth the general terms and provisions
of the Debt Securities that we may offer by this prospectus. We will describe
the particular terms of the Debt Securities, and provisions that vary from those
described below, in one or more prospectus supplements.

         We may issue the Debt Securities from time to time in the future, in
one or more series, under an indenture as it may be supplemented from time to
time (Indenture) between us and The Bank of New York, as trustee, or the
Indenture Trustee. A form of the Indenture is filed as an exhibit to the
registration statement relating to the Debt Securities.

         This section of the prospectus contains a summary of all material
provisions of the Indenture. The Indenture and its associated documents contain
the full legal text of the matters described in this section. Because this
section is a summary, it does not describe every aspect of the Debt Securities
or the Indenture. This summary is subject to and qualified in its entirety by
reference to all the provisions of the Indenture, including definitions of some
of the terms used in the Indenture. We also include references in parentheses to
some of the sections of the Indenture. Whenever we refer to particular sections
or defined terms of the Indenture in this prospectus or in a prospectus
supplement, these sections or defined terms are incorporated by reference into
this document or in the prospectus supplement. This summary also is subject to
and qualified by reference to the description of the particular terms of each
series of Debt Securities described in the applicable prospectus supplement or
supplements. The Indenture has been qualified under the Trust Indenture Act, and
you should also refer to the Trust Indenture Act for provisions that apply to
the Debt Securities.

         There is no requirement under the Indenture that future issuances of
debt securities be issued exclusively under the Indenture, and we will be free
to employ other indentures or agreements containing provisions different from
those included in the Indenture or applicable to one or more issues of debt
securities, in connection with future issues of the other debt securities.

GENERAL

         The Indenture permits us to issue an unlimited amount of Debt
Securities from time to time. All Debt Securities of any one series need not be
issued at the same time, and a series may be reopened for issuances of


                                       10



additional Debt Securities of that series. This means that we may from time to
time, without the consent of the existing holders of the Debt Securities of any
series, create and issue additional Debt Securities of a series having the same
terms and conditions as the previously-issued Debt Securities of that series in
all respects, except for issue date, issue price and, if applicable, the initial
interest payment on those additional Debt Securities. Additional Debt Securities
issued in this manner will be consolidated with, and will form a single series
with, the previously-issued Debt Securities of that series. For more
information, see the discussion below under "Issuance of Additional Debt
Securities."

         Until the Release Date (described below), the Debt Securities will be
issued on the basis of, and primarily secured by, (a) the lien of one or more
series of First Mortgage Bonds issued by us under the Mortgage (as these terms
are defined below under DESCRIPTION OF THE FIRST MORTGAGE BONDS) and any other
Class A Bonds issued by us and delivered by us to the Indenture Trustee and (b)
the lien of the Indenture on our Electric and Gas Utility Property (as defined
below under "Lien of the Indenture"). On the Release Date, the Debt Securities
will cease to be secured and will become our unsecured general obligations,
ranking on a parity with our other senior unsecured indebtedness. For more
information, see the discussions below under "Security," "Issuance of Additional
Debt Securities" and "Discharge of Lien; Release Date").

         A prospectus supplement and an officer's certificate relating to any
series of Debt Securities being offered will include specific terms relating to
that offering. These terms will include some or all of the following terms that
apply to that series:

     o    the title of the Debt Securities;

     o    any limit upon the total principal amount of the Debt Securities;

     o    the dates, or the method to determine these dates, on which the
          principal of the Debt Securities will be payable and how it will be
          paid;

     o    the interest rate or rates which the Debt Securities will bear, or how
          the rate or rates will be determined, the interest payment dates for
          the Debt Securities and the regular record dates for interest
          payments;

     o    any right to delay the interest payments for the Debt Securities;

     o    the percentage, if less than 100%, of the principal amount of the Debt
          Securities that will be payable if the maturity of the Debt Securities
          is accelerated;

     o    any date or dates on which the Debt Securities may be redeemed at our
          option and any restrictions on those redemptions;

     o    any sinking fund or other provisions that would obligate us to
          repurchase or otherwise redeem the Debt Securities;

     o    any additions to the events of default under the Indenture or
          additions to our covenants under the Indenture for the benefit of the
          holders of Debt Securities;

     o    if the Debt Securities will be issued in denominations other than
          multiples of $1,000;

     o    if payments on the Debt Securities may be made in a currency or
          currencies other than United States dollars; and, if so, the means
          through which the equivalent principal amount of any payment in United
          States dollars is to be determined for any purpose;

     o    any rights or duties of another entity to assume our obligations with
          respect to the Debt Securities;

     o    any collateral, security, assurance or guarantee for the Debt
          Securities; and


                                       11



     o    any other terms of the Debt Securities not inconsistent with the terms
          of the Indenture.

(Indenture, Section 301.)

         We may sell Debt Securities at a discount below their principal amount.
United States federal income tax considerations applicable to Debt Securities
sold at an original issue discount will be described in the prospectus
supplement if we sell Debt Securities at an original issue discount. In
addition, important United States federal income tax or other tax considerations
applicable to any Debt Securities denominated or payable in a currency or
currency unit other than United States dollars will be described in the
prospectus supplement if we sell Debt Securities denominated or payable in a
currency or currency unit other than United States dollars.

         Except as may otherwise be described in the applicable prospectus
supplement, the covenants contained in the Indenture will not afford holders of
Debt Securities protection in the event of a highly-leveraged transaction
involving us.

REDEMPTION

         We will set forth any terms for the redemption of Debt Securities of
any series in the applicable prospectus supplement. Unless we indicate
differently in a prospectus supplement, and except with respect to Debt
Securities redeemable at the option of the holder of those Debt Securities, Debt
Securities will be redeemable upon notice to holders by mail at least 30 days
prior to the redemption date. (Indenture, Section 504.) If less than all of the
Debt Securities of any series or any tranche thereof are to be redeemed, the
Indenture Trustee will select the Debt Securities to be redeemed. In the absence
of any provision for selection, the Indenture Trustee will choose a method of
random selection as it deems fair and appropriate. (Indenture, Section 503.)

         Debt securities will cease to bear interest on the redemption date. We
will pay the redemption price and any accrued interest to the redemption date
upon surrender of any Debt Security for redemption. (Indenture, Section 505.) If
only part of a Debt Security is redeemed, the Indenture Trustee will deliver to
the holder of the Debt Security a new Debt Security of the same series for the
remaining portion without charge. (Indenture, Section 506.)

         We may make any redemption at our option conditional upon the receipt
by the paying agent, on or prior to the date fixed for redemption, of money
sufficient to pay the redemption price. If the paying agent has not received the
money by the date fixed for redemption, we will not be required to redeem the
Debt Securities. (Indenture, Section 504.)

PAYMENT AND PAYING AGENTS

         Except as may be provided in the applicable prospectus supplement,
interest, if any, on each Debt Security payable on any interest payment date
will be paid to the person in whose name that Debt Security is registered at the
close of business on the regular record date for that interest payment date.
However, interest payable at maturity will be paid to the person to whom the
principal is paid. If there has been a default in the payment of interest on any
Debt Security, the defaulted interest may be paid to the holder of that Debt
Security as of the close of business on a date between 10 and 15 days before the
date proposed by us for payment of the defaulted interest or in any other manner
permitted by any securities exchange on which that Debt Security may be listed,
if the Indenture Trustee finds it workable. (Indenture, Section 307.)

         Unless otherwise specified in the applicable prospectus supplement,
principal, premium, if any, and interest on the Debt Securities at maturity will
be payable upon presentation of the Debt Securities at the corporate trust
office of The Bank of New York, in the city of New York, as our paying agent.
However, we may choose to make payment of interest by check mailed to the
address of the persons entitled to payment. We may change the place of payment
on the Debt Securities, appoint one or more additional paying agents (including
MDU) and remove any paying agent, all at our discretion. (Indenture, Section
702.)


                                       12



REGISTRATION AND TRANSFER

         Unless otherwise specified in the applicable prospectus supplement, the
transfer of Debt Securities may be registered, and Debt Securities may be
exchanged for other Debt Securities of the same series or tranche, of authorized
denominations and with the same terms and principal amount, at the offices of
the Indenture Trustee in New York, New York. (Indenture, Section 305.) We may
designate one or more additional places, or change the place or places
previously designated, for registration of transfer and exchange of the Debt
Securities. (Indenture, Section 702.) Unless otherwise specified in the
applicable prospectus supplement, no service charge will be made for any
registration of transfer or exchange of the Debt Securities. However, we may
require payment to cover any tax or other governmental charge that may be
imposed in connection with a registration of transfer or exchange. We will not
be required to execute or to provide for the registration, transfer or exchange
of any Debt Security

     o    during the 15 days before an interest payment date;

     o    during the 15 days before giving any notice of redemption; or

     o    selected for redemption except the unredeemed portion of any Debt
          Security being redeemed in part.

(Indenture, Section 305.)

SECURITY

         Except as described below under this heading and under "Issuance of
Additional Debt Securities," and subject to the exceptions discussed under
"Discharge of Lien; Release Date," all Debt Securities will be secured, equally
and ratably, by:

         (1)      the first lien of an equal principal amount of First Mortgage
                  Bonds delivered by us to the Indenture Trustee, and other
                  Class A Bonds as described below; as discussed under
                  DESCRIPTION OF THE FIRST MORTGAGE BONDS - "Security and
                  Priority," the Mortgage constitutes a first mortgage lien on
                  the Mortgaged Property; and

         (2)      the lien of the Indenture, which is junior to the lien of the
                  Mortgage, upon our Electric and Gas Utility Property (as
                  defined below under Lien of the Indenture). If we acquire any
                  property that is subject to a Class A Mortgage (as described
                  below), the lien of the Indenture would be junior to the lien
                  of that Class A Mortgage with respect to any of our Electric
                  and Gas Utility Property subject to the lien of that Class A
                  Mortgage.

         See "Discharge of Lien; Release Date" for a discussion of provisions of
the Indenture pursuant to which, subject to the satisfaction of the specified
conditions, the lien of the Indenture would be discharged and the Debt
Securities would become our unsecured obligations.

CLASS A BONDS

         As discussed below under "Consolidation, Merger and Conveyance of
Assets," we will be permitted to merge or consolidate with another company upon
meeting specified requirements. Following a merger or consolidation of another
company into us, we could deliver to the Indenture Trustee first mortgage bonds
issued under an existing mortgage on the properties of the other company as the
basis for the issuance of additional Debt Securities. In this event, the Debt
Securities would be secured, additionally, by the first lien of the first
mortgage bonds and by the lien of the Indenture on the mortgaged property
acquired from the other company, which would be junior to the lien of the
existing mortgage. The Mortgage and all the other mortgages are collectively
referred to in this document as the "Class A Mortgages," and all first mortgage
bonds issued under the Class A Mortgages are collectively referred to in this
document as the "Class A Bonds." (Indenture, Section 1706.)

         Class A Bonds, including First Mortgage Bonds, that are the basis for
the authentication and delivery of Debt Securities (a) will be delivered to, and
registered in the name of, the Indenture Trustee or its nominee and will be
owned and held by the Indenture Trustee, subject to the provisions of the
Indenture, for the benefit of the holders of all Debt Securities outstanding


                                       13



from time to time; (b) will mature or be subject to mandatory redemption on the
same dates, and in the same principal amounts, as the Debt Securities; and
(c)(i) may, but need not, bear interest and (ii) may, but need not, contain
provisions for their redemption at our option, any redemption to be made at a
redemption price or prices not less than the principal amount of the Class A
Bonds. (Indenture, Sections 1602 and 1701.) To the extent that Class A Bonds do
not bear interest, holders of Debt Securities will not have the benefit of the
lien of a Class A Mortgage in respect of an amount equal to accrued interest, if
any, on the Debt Securities; however, the holders will nevertheless have the
benefit of the lien of the Indenture in respect of the amount of accrued
interest.

         Any payment by us of principal of or premium or interest on the Class A
Bonds delivered to and held by the Indenture Trustee will be applied by the
Indenture Trustee to the payment of any principal, premium or interest, as the
case may be, in respect of the Debt Securities which is then due. Our obligation
under the Indenture to make payment in respect of the Debt Securities will be
deemed satisfied and discharged to the extent of the payment. If, at the time of
any payment of principal of Class A Bonds, there is no principal then due in
respect of the Debt Securities, the proceeds of the payment will constitute
"Funded Cash" and will be held by the Indenture Trustee as part of the
collateral for the Debt Securities, to be withdrawn, used or applied as provided
in the Indenture. If, at the time of any payment of premium or interest on Class
A Bonds, there is no premium or interest then due on the Debt Securities, the
payment will be remitted to us at our request; except that, if any event of
default under the Indenture, as described below, has occurred and is continuing,
the payment will be held as part of the collateral for the Debt Securities until
the event of default under the Indenture has been cured or waived. (Indenture,
Section 1702.) See "Withdrawal of Cash" below.

         Any payment by us on Debt Securities authenticated and delivered on the
basis of the delivery to the Indenture Trustee of Class A Bonds (other than by
application of the proceeds of a payment in respect of the Class A Bonds) will,
to that extent, be deemed to satisfy and discharge our obligations, if any, to
make a corresponding payment, in respect of the Class A Bonds which is then due.
(Indenture, Section 1702.)

         The Indenture Trustee may not sell, assign or otherwise transfer any
Class A Bonds except to a successor trustee under the Indenture. (Indenture,
Section 1704.) At the time any Debt Securities that have been authenticated and
delivered upon the basis of Class A Bonds cease to be outstanding (other than as
a result of the application of the proceeds of the payment or redemption of the
Class A Bonds), the Indenture Trustee will surrender to us, or upon our order,
an equal principal amount of the Class A Bonds.
(Indenture, Section 1703.)

         When the aggregate principal amount of all Class A Bonds outstanding
under all Class A Mortgages, other than those held by the Indenture Trustee,
does not exceed the greater of 5% of the net book value of our Electric and Gas
Utility Property (as described below) or 5% of our Capitalization (as described
below), then, at our request and subject to satisfaction of specified
conditions, the Class A Bonds held by the Indenture Trustee will be deemed
satisfied and discharged, the Indenture Trustee will surrender the Class A Bonds
for cancellation, and the Debt Securities will become our senior unsecured debt,
subject to Permitted Secured Debt and the exceptions described below.
(Indenture, Section 1811.) See "Discharge of Lien; Release Date" below.

         At the date of this prospectus, the only Class A Mortgage is the
Mortgage, and the only Class A Bonds issuable at this time are First Mortgage
Bonds issuable under the Mortgage. When all of the outstanding First Mortgage
Bonds which are not held by the Indenture Trustee do not exceed the greater of
5% of the net book value of our Electric and Gas Utility Property or 5% of our
Capitalization, and assuming no other Class A Mortgage exists at the time, the
Indenture may become unsecured.

         "Capitalization" means the total of all the following items appearing
on, or included in, our unconsolidated balance sheet; (i) liabilities for
indebtedness maturing more than 12 months from the date of determination, and
(ii) common stock, common stock expense, accumulated other comprehensive income
or loss, preferred stock, preference stock, premium on common stock and retained
earnings (however the foregoing may be designated), less, to the extent not
otherwise deducted, the cost of shares of our capital stock held in our
treasury, if any. Capitalization is determined in accordance with generally
accepted accounting principles and practices applicable to the type of business
in which we are engaged, and may be determined as of the date not more than 60
days prior to the happening of the event for which the determination is being
made.

LIEN OF THE INDENTURE

         The Indenture creates a lien on substantially all of our fixed
electricity generation, transmission and distribution, and natural gas
distribution, properties owned by us immediately prior to July 1, 2000, together
with improvements, extensions and additions to, and renewals, replacements and
substitutions of or for, any part or parts of these properties, other than
Excepted Property (as defined below). At the date of this prospectus, these
properties are located in the states of North Dakota, South Dakota, Montana and
Wyoming. These properties, regardless of whether the Release Date has occurred,
are sometimes referred to as our "Electric and Gas Utility Property." At the
date of this prospectus, substantially all of this property is included within
the category of property, plant and equipment on our balance sheet, this
property had a net book value as of March 31, 2003 of approximately $363.5
million, and this property, while subject to the lien of the Indenture, is also
subject to the prior lien of the Mortgage. For so long as the Release Date has
not occurred, the Debt Securities will have the benefit of the first mortgage
lien of the Mortgage on the Mortgaged Property to the extent of the aggregate
principal amount of First Mortgage Bonds held by the Indenture Trustee, and also
the benefit of the lien of any additional Class A Mortgage on any property
subject to that Class A Mortgage to the extent of the aggregate principal amount
of Class A Bonds, issued under that Class A Mortgage, held by the Indenture
Trustee.

PERMITTED LIENS

         The lien of the Indenture is subject to Permitted Liens described in
the Indenture. These Permitted Liens include liens existing at the execution
date of the Indenture such as the lien of the Mortgage, liens on property at the
time we acquire the property such as the lien of any other Class A Mortgage, tax
liens and other governmental charges which are not delinquent or which are being
contested in good faith, mechanics', construction and materialmen's liens,
specified judgment liens, easements, reservations and rights of others
(including governmental entities) in, and defects of title in, our property,
specified leases and leasehold interests, liens to secure public obligations,
rights of others to take minerals, timber, electric energy or capacity, gas,
water, steam or other products produced by us or by others on our property,
rights and interests of Persons other than us arising out of agreements relating
to the common ownership or joint use of property, and liens on the interests of
those Persons in the property, liens which have been bonded or for which other
security arrangements have been made, liens created in connection with the
issuance of tax-exempt bonds, purchase money liens and liens related to the
construction or acquisition of property, or the development or expansion of
property, liens which secure specified Debt Securities equally and ratably with
other obligations, and additional liens on any of our property (other than
Excepted Property, as described below) to secure debt for borrowed money in an
aggregate principal amount not exceeding the greater of 10% of our Net Tangible
Assets (as described below) or 10% of our Capitalization. (Indenture, Granting
Clauses and Sections 101 and 707.)

         The Indenture provides that the Indenture Trustee will have a lien,
prior to the lien on behalf of the holders of Debt Securities, upon the
collateral for the Debt Securities for the payment of its reasonable
compensation and expenses and for indemnity against specified liabilities.
(Indenture, Section 1007.) This lien would be a Permitted Lien under the
Indenture.

EXCEPTED PROPERTY

         The lien of the Indenture does not cover, among other things, the
following types of property:

o    all properties acquired by us on or after July 1, 2000, including the
     properties acquired in the merger with Great Plains Energy Corp. and Great
     Plains Natural Gas Co. (which include all our gas distribution properties
     located in the state of Minnesota and certain gas distribution properties
     located in the southeastern part of North Dakota), but excluding
     improvements, extensions and additions to, and renewals, replacements and
     substitutions of or for, any part or parts of the fixed electricity
     generation, transmission and distribution, and natural gas distribution,
     properties owned by us immediately prior to July 1, 2000 unless otherwise
     excepted from the lien of the Indenture;

o    all property of subsidiaries, including Centennial Energy Holdings, Inc.,
     WBI Holdings, Inc., Knife River Corporation, Utility Services, Inc.,
     Centennial Energy Resources LLC, Centennial Holdings Capital LLC,


                                       15



     Centennial Energy Resources International Inc, Fidelity Exploration &
     Production Company and any other subsidiaries;

o    all cash and securities (including the capital stock of the subsidiaries
     mentioned in the preceding bullet and any other subsidiaries) not paid,
     deposited or held under the Indenture, and all policies of insurance on the
     lives of our officers;

o    all contracts, leases and other agreements of all kinds, contract rights,
     bills, notes and other instruments, accounts receivable, transition
     property, claims, demands and judgments;

o    all governmental and other licenses, permits, franchises, consents and
     allowances; intellectual property rights and other general intangibles;

o    all vehicles, movable equipment, aircraft and vessels;

o    all merchandise and appliances acquired for the purpose of resale in the
     ordinary course and conduct of our business, and all materials and supplies
     held for consumption in operation or held in advance of use thereof for
     fixed capital purposes;

o    all electric energy, gas, steam and other materials and products generated,
     manufactured, produced or purchased by us for sale, distribution or use in
     the ordinary course and conduct of our business;

o    all property which is the subject of a lease agreement designating us as
     lessee, and all our right, title and interest in and to the property and
     in, to and under the lease agreement, whether or not the lease agreement is
     intended as security;

o    all property which prior to the execution date of the Indenture has been
     released from the lien of the Mortgage;

o    all property which subsequent to the execution date of the Indenture has
     been released from the lien of the Indenture; and

o    any and all property not acquired or constructed by us for use in our
     electricity generation, transmission and distribution, and natural gas
     distribution business.

We sometimes refer to property of ours not covered by the lien of the Indenture
as "Excepted Property." (Indenture, Granting Clauses.)

         We may enter into supplemental indentures with the Indenture Trustee,
without the consent of the holders, in order to subject additional property
(including property that would otherwise be excepted from the lien) to the lien
of the Indenture. (Indenture, Section 1301.) This property would then constitute
Property Additions and part of the collateral for the Debt Securities, and would
be available as a basis for the issuance of Debt Securities. See "Issuance of
Additional Debt Securities."

         The Indenture provides that after-acquired properties (other than
Excepted Property) that are improvements, extensions or additions to, or
renewals, replacements or substitutions of or for, any part or parts of our
Electric and Gas Utility Property will be subject to the lien of the Indenture.
(Indenture, Second Granting Clause.) We may also elect to subject additional
property to the lien of the Indenture by amending the Indenture.

         See "Discharge of Lien; Release Date" for a discussion of provisions of
the Indenture pursuant to which, subject to the satisfaction of specified
conditions, all the collateral for the Debt Securities would be released from
the lien of the Indenture, the Class A Bonds held by the Indenture Trustee would
be surrendered for cancellation, and Debt Securities would become our unsecured
obligations.



                                       16



ISSUANCE OF ADDITIONAL DEBT SECURITIES

         Subject to the issuance restrictions described below, the maximum
principal amount of Debt Securities that may be authenticated and delivered
under the Indenture is unlimited. (Indenture, Section 301.) Prior to the Release
Date, Debt Securities of any series may be issued from time to time on the basis
of, and in an aggregate principal amount not exceeding:

o    the aggregate principal amount of Class A Bonds delivered to the Indenture
     Trustee;

o    70% of the Cost or Fair Value to us (whichever is less) of Property
     Additions (as described below) which do not constitute Funded Property
     (generally, Property Additions which have been made the basis of the
     authentication and delivery of Debt Securities, the release of collateral
     for the Debt Securities or the withdrawal of cash, which have been
     substituted for retired Funded Property or which have been used for other
     specified purposes) after specified deductions and additions, primarily
     including adjustments to offset property retirements;

o    the aggregate principal amount of retired Debt Securities, but if Class A
     Bonds had been made the basis for the authentication and delivery of the
     retired Debt Securities, only after the discharge of the related Class A
     Mortgage; or

o    an amount of cash deposited with the Indenture Trustee.

(Indenture, Sections 1602 through 1605.)

         Property Additions generally include any property that is owned by us
and is subject to the lien of the Indenture. (Indenture, Section 103.)

         We expect that, until the Release Date, we will issue Debt Securities
primarily on the basis of First Mortgage Bonds. However, we have the right to
issue additional Debt Securities on the basis of Property Additions, retired
Debt Securities and cash deposits, and Class A Bonds not issued under the
Mortgage.

RELEASE OF PROPERTY

         Unless an event of default under the Indenture has occurred and is
continuing, we may obtain the release from the lien of the Indenture of any
collateral for the Debt Securities, except for cash held by the Indenture
Trustee, upon delivery to the Indenture Trustee of an amount in cash equal to
the amount, if any, by which the Cost of the property to be released (or, if
less, the Fair Value to us of the property at the time it became Funded
Property) exceeds the aggregate of:

o    an amount equal to the aggregate principal amount of obligations secured by
     Purchase Money Liens upon the property to be released and delivered to the
     Indenture Trustee;

o    an amount equal to the Cost or Fair Value to us (whichever is less) of
     certified Property Additions not constituting Funded Property after
     specified deductions and additions, primarily including adjustments to
     offset property retirements (except that these adjustments need not be made
     if the Property Additions were acquired or made within the 90-day period
     preceding the release);

o    the aggregate principal amount of Debt Securities that we would be entitled
     to issue on the basis of retired Debt Securities (with the entitlement
     being waived by operation of the release);

o    any amount of cash and/or an amount equal to the aggregate principal amount
     of obligations secured by Purchase Money Liens upon the property released
     delivered to the trustee or other holder of a lien prior to the lien of the
     Indenture, subject to specified limitations described below;

o    the aggregate principal amount of Debt Securities delivered to the
     Indenture Trustee (with the Debt Securities to be canceled by the Indenture
     Trustee); and



                                       17


o    any taxes and expenses incidental to any sale, exchange, dedication or
     other disposition of the property to be released.

o    (Indenture, Section 1803.)

         Property that is not Funded Property may generally be released from the
lien of the Indenture without depositing any cash or property with the Indenture
Trustee as long as (a) the aggregate amount of Cost or Fair Value to us
(whichever is less) of all Property Additions which do not constitute Funded
Property (excluding the property to be released) after some deductions and
additions, primarily including adjustments to offset property retirements, is
not less than zero or (b) the Cost or Fair Value (whichever is less) of property
to be released does not exceed the aggregate amount of the Cost or Fair Value to
us (whichever is less) of Property Additions acquired or made within the 90-day
period preceding the release. (Indenture, Section 1804.)

         The Indenture provides simplified procedures for the release of
property which has been released from the lien of a Class A Mortgage, minor
properties and property taken by eminent domain, and provides for dispositions
of certain obsolete property and grants or surrender of certain rights without
any release or consent by the Indenture Trustee. (Indenture Sections 1802, 1805,
1807 and 1808.)

         If we retain any interest in any property released from the lien of the
Indenture, the Indenture will not become a lien on the property or the interest
in the property or any improvements, extensions or additions to, or any
renewals, replacements or substitutions of or for, any part or parts of the
property. (Indenture, Section 1810.)

WITHDRAWAL OF CASH

         Unless an event of default under the Indenture has occurred and is
continuing, and subject to specified limitations, cash held by the Indenture
Trustee may, generally, (1) be withdrawn by us (a) to the extent of the Cost or
Fair Value to us (whichever is less) of Property Additions not constituting
Funded Property, after specified deductions and additions, primarily including
adjustments to offset retirements (except that these adjustments need not be
made if the Property Additions were acquired or made within the 90-day period
preceding the withdrawal) or (b) in an amount equal to the aggregate principal
amount of Debt Securities that we would be entitled to issue on the basis of
retired Debt Securities (with the entitlement to the issuance being waived by
operation of the withdrawal) or (c) in an amount equal to the aggregate
principal amount of any outstanding Debt Securities delivered to the Indenture
Trustee, or (2) upon our request, be applied to (a) the purchase of Debt
Securities or (b) the payment (or provision for payment) at stated maturity of
any Debt Securities or the redemption (or provision for payment) of any Debt
Securities which are redeemable (Indenture, Section 1806); except that cash
deposited with the Indenture Trustee as the basis for the authentication and
delivery of Debt Securities, as well as cash representing a payment of principal
of Class A Bonds, may, in addition, be withdrawn in an amount equal to the
aggregate principal amount of Class A Bonds delivered to the Indenture Trustee.
(Indenture, Sections 1605 and 1702.)

DISCHARGE OF LIEN; RELEASE DATE

         At any time when the aggregate principal amount of all Class A Bonds
outstanding under all Class A Mortgages, other than those held by the Indenture
Trustee, does not exceed the greater of 5% of the net book value of our Electric
and Gas Utility Property or 5% of our Capitalization, the Indenture may be
amended and supplemented, without the consent of the holders of Debt Securities
or any other Debt Securities, to eliminate all terms and conditions relating to
collateral for the Debt Securities, with the result that our obligations under
the Indenture and the Debt Securities would be entirely unsecured. We refer to
the date on which the elimination of collateral occurs as the "Release Date."

         The occurrence of the Release Date is subject to our delivery of the
following documents to the Indenture Trustee:

o    a company order requesting execution and delivery by the Indenture Trustee
     of a supplemental indenture and other instruments necessary to discharge,
     cancel, terminate or satisfy the lien of the Indenture;

o    an officer's certificate stating that



                                       18



               (1)  to the knowledge of the officer, no event of default under
                    the Indenture has occurred and is continuing; and

               (2)  the aggregate principal amount of all Class A Bonds
                    outstanding under all Class A Mortgages, other than those
                    held by the Indenture Trustee, does not exceed the greater
                    of 5% of the net book value of our Electric and Gas Utility
                    Property or 5% of our Capitalization; and

o    an opinion of counsel to the effect that none of our Electric and Gas
     Utility Property, other than Excepted Property, is subject to any lien
     other than the lien of the Indenture and Permitted Liens.

         Upon the execution and delivery of the amendment of the Indenture as
contemplated above, the lien of the Indenture will be deemed to have been
satisfied and discharged and the Indenture Trustee will release the collateral
for the Debt Securities from the lien of the Indenture and surrender all Class A
Bonds held by the Indenture Trustee under the Indenture to the respective Class
A Trustee for cancellation. (Indenture, Section 1811.)

         As of March 31, 2003, we had $35 million aggregate principal amount
outstanding of a series of First Mortgage Bonds that is not redeemable prior to
maturity and matures on April 1, 2012. Unless we purchase or defease some of
this series of First Mortgage Bonds or increase the net book value of our
Electric and Gas Utility Property or our Capitalization to at least $700
million, a Release Date is unlikely to occur prior to April 1, 2012.


LIMITATION ON SECURED DEBT

         So long as any of the Debt Securities remain outstanding, we will not
issue any Secured Debt other than Permitted Secured Debt (in each case as
defined below) without the consent of the holders of a majority in principal
amount of the outstanding Debt Securities of all series with respect to which
this covenant is made, considered as one class; provided, however, that this
covenant will not prohibit the creation or existence of any Secured Debt if
either:

o    we make effective provision whereby all Debt Securities then outstanding
     will be secured equally and ratably with the Secured Debt; or

o    we deliver to the Indenture Trustee bonds, notes or other evidences of
     indebtedness secured by the lien which secures the Secured Debt in an
     aggregate principal amount equal to the aggregate principal amount of the
     Debt Securities then outstanding and meeting other requirements set forth
     in the Indenture.

         "Secured Debt" means Debt created, issued, incurred or assumed by us
which is secured by a lien upon any of our property (other than Excepted
Property). For purposes of this covenant, any Capitalized Lease Liabilities will
be deemed to be Debt secured by a lien on our property.

         "Debt" means:

o    our indebtedness for borrowed money evidenced by a bond, debenture, note or
     other written instrument or agreement by which we are obligated to repay
     the borrowed money;

o    any guaranty by us of any indebtedness of another person; and

o    any Capitalized Lease Liabilities.

         "Debt" does not include, among other things:

o    indebtedness under any installment sale or conditional sale agreement or
     any other agreement relating to indebtedness for the deferred purchase
     price of property or services;


                                       19



o    any trade obligations (including any obligations under power or other
     commodity purchase agreements and any associated hedges or derivatives) or
     other obligations in the ordinary course of business;

o    obligations under any lease agreement that are not Capitalized Lease
     Liabilities; or

o    any liens securing indebtedness, neither assumed nor guaranteed by us nor
     on which we customarily pay interest, existing upon real estate or rights
     in or relating to real estate acquired by us for substation, transmission
     line, transportation line, distribution line or right of way purposes.

         "Permitted Secured Debt" means, as of any particular time:

o        Class A Bonds and Debt Securities issued prior to the Release Date;

o    Secured Debt which matures less than one year from the date of the issuance
     or incurrence and is not extendible at the option of the issuer; and any
     refundings, refinancings and/or replacements of any the Secured Debt by or
     with Secured Debt that matures less than one year from the date of the
     refunding, refinancing and/or replacement and is not extendible at the
     option of the issuer;

o    Secured Debt secured by Purchase Money Liens or any other liens existing or
     placed upon property at the time of, or within one hundred eighty (180)
     days after, the acquisition thereof by us, and any refundings, refinancings
     and/or replacements of any the Secured Debt; provided, however, that no
     Purchase Money Lien or other Lien of this type will extend to or cover any
     of our property other than (1) the property so acquired and improvements,
     extensions and additions to the property and renewals, replacements and
     substitutions of or for the property or any part or parts of the property
     and (2) with respect to Purchase Money Liens, other property subsequently
     acquired by us;

o    Secured Debt relating to governmental obligations the interest on which is
     not included in gross income for purposes of federal income taxation
     pursuant to Section 103 of the Internal Revenue Code of 1986, as amended
     (or any successor provision of law), for the purpose of financing or
     refinancing, in whole or in part, costs of acquisition or construction of
     property to be used by us, to the extent that the lien which secures the
     Secured Debt is required either by applicable law or by the issuer of the
     governmental obligations or is otherwise necessary in order to establish or
     maintain the exclusion from gross income; and any refundings, refinancings
     and/or replacements of any Secured Debt by or with similar Secured Debt;

o    Secured Debt (i) which is related to the construction or acquisition of
     property not previously owned by us or (ii) which is related to the
     financing of a project involving the development or expansion of our
     property and (iii) in either case, the obligee in respect of which has no
     recourse to us or any of our property other than the property constructed
     or acquired with the proceeds of the transaction or the project financed
     with the proceeds of the transaction (or the proceeds of the property or
     the project); and any refundings, refinancings and/or replacements of any
     Secured Debt by or with Secured Debt described in clause (iii) above; and

o    in addition to the Permitted Secured Debt described above, Secured Debt not
     otherwise so permitted in an aggregate principal amount not exceeding the
     greater of 10% of our Net Tangible Assets or 10% of our Capitalization.

         "Net Tangible Assets" means the amount shown as total assets on our
unconsolidated balance sheet, less (i) intangible assets including, but without
limitation, such items as goodwill, trademarks, trade names, patents,
unamortized debt discount and expense and other regulatory assets carried as
assets on our unconsolidated balance sheet and (ii) appropriate adjustments, if
any, on account of minority interests. Net Tangible Assets will be determined in
accordance with generally accepted accounting principles and practices
applicable to the type of business in which we are engaged.

         "Capitalized Lease Liabilities" means the amount, if any, shown as
liabilities on our unconsolidated balance sheet for capitalized leases of
electric transmission and distribution property not owned by us, which amount


                                       20



will be determined in accordance with generally accepted accounting principles
and practices applicable to the type of business in which we are engaged.

(Indenture, Section 707.)

DEFEASANCE

         We will be discharged from our obligations on the Debt Securities of a
particular series if we irrevocably deposit with the Indenture Trustee or any
paying agent, other than us, sufficient cash or government securities to pay the
principal, interest, any premium and any other sums when due on the stated
maturity date or a redemption date of that series of Debt Securities.
(Indenture, Section 801.)

CONSOLIDATION, MERGER AND CONVEYANCE OF ASSETS

         Under the terms of the Indenture, we may not consolidate with or merge
into any other entity or convey, transfer or lease as or substantially as an
entirety to any entity our Electric and Gas Utility Property, unless:

o    the surviving or successor entity, or an entity which acquires by
     conveyance or transfer or which leases our Electric and Gas Utility
     Property as, or substantially as, an entirety, is organized and validly
     existing under the laws of any domestic jurisdiction and it expressly
     assumes our obligations on all Debt Securities then outstanding under the
     Indenture and if the consolidation, merger, conveyance, sale or other
     transfer occurs prior to the Release Date, confirms the lien of the
     Indenture on the collateral for the Debt Securities;

o    in the case of a lease, the lease is made expressly subject to termination
     by us or by the Indenture Trustee and by the purchaser of the property so
     leased at any sale thereof at any time during the continuance of an event
     of default under the Indenture;

o    we shall have delivered to the Indenture Trustee an officer's certificate
     and an opinion of counsel as provided in the Indenture; and

o    immediately after giving effect to the transaction, no event of default
     under the Indenture, or event which, after notice or lapse of time or both,
     would become an event of default under the Indenture, shall have occurred
     and be continuing.

(Indenture, Section 1201.) In the case of the conveyance or other transfer of
the Electric and Gas Utility Property as or substantially as an entirety to any
other person, upon the satisfaction of all the conditions described above, we
would be released and discharged from all our obligations under the Indenture
and on the Debt Securities then outstanding unless we elect to waive release and
discharge. (Indenture, Section 1204.)

         The Indenture does not prevent or restrict:

o    any conveyance or other transfer, or lease, of any part of our Electric and
     Gas Utility Property that does not constitute the entirety, or
     substantially the entirety, of our Electric and Gas Utility Property; or
     (Indenture, Section 1205.)

o    any conveyance, transfer or lease of any of our properties where we retain
     Electric and Gas Utility Property with a fair value in excess of 143% of
     the aggregate principal amount of all outstanding Debt Securities, and any
     other outstanding debt securities that rank equally with, or senior to, the
     Debt Securities with respect to the Electric and Gas Utility Property,
     other than any Class A Bonds held by the Indenture Trustee. This fair value
     will be determined within 90 days of the conveyance, transfer or lease by
     an independent expert that we select and that is approved by the Indenture
     Trustee. (Indenture, Section 1206.)

The terms of the Indenture do not restrict us in a merger in which we are the
surviving entity. (Indenture, Section 1205.)


                                       21



EVENTS OF DEFAULT

         "Event of default," when used in the Indenture with respect to Debt
Securities, means any of the following:

o    failure to pay interest on any Debt Security for 30 days after it is due;

o    failure to pay the principal of or any premium on any Debt Security when
     due;

o    failure to perform any other covenant in the Indenture that continues for
     90 days after we receive written notice from the Indenture Trustee, or we
     and the Indenture Trustee receive a written notice from the holders of at
     least 33% in aggregate principal amount of the outstanding Debt Securities;

o    events of bankruptcy, insolvency or our reorganization as specified in the
     Indenture;

o    as long as the Indenture Trustee holds any outstanding Class A Bonds which
     were delivered as the basis for the authentication and delivery of
     outstanding Debt Securities, the occurrence of a matured event of default
     under the related Class A Mortgage (other than a matured event of default
     which (i) is not a failure to make payments on Class A Bonds and is not of
     similar kind or character to the event of default relating to events of
     bankruptcy, insolvency or reorganization, referred to above, and (ii) has
     not resulted in the acceleration of the outstanding Class A Bonds under the
     Class A Mortgage); provided, however, that the waiver or cure of the event
     of default under a Class A Mortgage will constitute a waiver and cure of
     the corresponding event of default under the Indenture, and the rescission
     and annulment of the consequences thereof will constitute a rescission and
     annulment of the corresponding consequences under the Indenture; or

o    any other event of default included in any supplemental indenture or
     officer's certificate for that series of Debt Securities.

(Indenture, Sections 901 and 1301.)

REMEDIES

         If an event of default under the Indenture occurs and is continuing,
then the Indenture Trustee or the holders of at least 33% in aggregate principal
amount of the outstanding Debt Securities may declare the principal amount of
all of the Debt Securities to be due and payable immediately.

         At any time after a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Indenture Trustee, the event of default under the Indenture giving rise to
the declaration of acceleration will be considered cured, and the declaration
and its consequences will be considered rescinded and annulled, if:

o    we have paid or deposited with the Indenture Trustee a sum sufficient to
     pay:

               (1)  all overdue interest on all outstanding Debt Securities;

               (2)  the principal of and premium, if any, on the outstanding
                    Debt Securities that have become due otherwise than by the
                    declaration of acceleration and overdue interest thereon;

               (3)  interest on overdue interest to the extent lawful; and (4)
                    all amounts due to the Indenture Trustee under the
                    Indenture; and

o    any other event of default under the Indenture with respect to the Debt
     Securities of that series has been cured or waived as provided in the
     Indenture.

(Indenture, Section 902.)

         There is no automatic acceleration, even in the event of our
bankruptcy, insolvency or reorganization.


                                       22



         Subject to the Indenture, under specified circumstances and to the
extent permitted by law, if an event of default under the Indenture occurs and
is continuing prior to the Release Date, the Indenture Trustee has the power to
appoint a receiver of the collateral for the Debt Securities, and is entitled to
all other remedies available to mortgagees and secured parties under the Uniform
Commercial Code or any other applicable law. (Indenture, Section 917.)

         Upon the occurrence and continuance of an event of default under the
Indenture after the Release Date, the remedies of the Indenture Trustee and the
holders under the Indenture would be limited to the rights of unsecured
creditors.

         In addition to every other right and remedy provided in the Indenture,
the Indenture Trustee may exercise any right or remedy available to the
Indenture Trustee in its capacity as owner and holder of Class A Bonds which
arises as a result of a default or matured event of default under any Class A
Mortgage, whether or not an event of default under the Indenture has occurred
and is continuing. (Indenture, Section 916.)

         Other than its duties in case of an event of default under the
Indenture, the Indenture Trustee is not obligated to exercise any of its rights
or powers under the Indenture at the request, order or direction of any of the
holders, unless the holders offer the Indenture Trustee a reasonable indemnity.
(Indenture, Section 1003.) If they provide this reasonable indemnity, the
holders of a majority in principal amount of the outstanding Debt Securities
will have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Indenture Trustee, or exercising any
power conferred upon the Indenture Trustee. The Indenture Trustee is not
obligated to comply with directions that conflict with law or other provisions
of the Indenture. (Indenture, Section 912.)

         No holder of Debt Securities will have any right to institute any
proceeding under the Indenture, or any remedy under the Indenture, unless:

o    the holder has previously given to the Indenture Trustee written notice of
     a continuing event of default under the Indenture;

o    the holders of a majority in aggregate principal amount of the outstanding
     Debt Securities of all series have made a written request to the Indenture
     Trustee, and have offered reasonable indemnity to the Indenture Trustee to
     institute proceedings; and

o    the Indenture Trustee has failed to institute any proceeding for 60 days
     after notice and has not received during that period any direction from the
     holders of a majority in aggregate principal amount of the outstanding Debt
     Securities, inconsistent with the written request of holders referred to
     above.

         (Indenture, Section 907.) However, these limitations do not apply to a
suit by a holder of an Debt Security for payment of the principal, premium, if
any, or interest on the Debt Security on or after the applicable due date.
(Indenture, Section 908.)

         We will provide to the Indenture Trustee an annual statement by an
appropriate officer as to our compliance with all conditions and covenants under
the Indenture. (Indenture, Section 705.)

MODIFICATION AND WAIVER

         Without the consent of any holder of Debt Securities, we and the
Indenture Trustee may enter into one or more supplemental indentures for any of
the following purposes:

o    to evidence the assumption by any permitted successor of our covenants in
     the Indenture and in the Debt Securities;

o    to permit an entity acquiring a substantial portion of our Electric and Gas
     Utility Property to assume a pro rata share of the outstanding Debt
     Securities based upon the net book value of the Electric and Gas Utility
     Property acquired by that entity and to release us and our properties from
     any obligations or liens under the Indenture with respect to those assumed


                                       23



     Debt Securities, provided that the assumed Debt Securities will be secured
     by a lien on the acquired Electric and Gas Utility Property to
     substantially the same extent and upon substantially the same terms as
     provided in the Indenture except for the substitution of the acquiring
     entity for us;

o    to add one or more covenants or other provisions for the benefit of the
     holders of all or any series or tranche of Debt Securities, or to surrender
     any right or power conferred upon us;

o    to add additional events of default under the Indenture for all or any
     series of Debt Securities;

o    to change or eliminate or add any provision to the Indenture; provided,
     however, if the change will adversely affect the interests of the holders
     of Debt Securities of any series in any material respect, the change,
     elimination or addition will become effective only:

               (1)  when the consent of the holders of Debt Securities of such
                    series has been obtained in accordance with the Indenture;
                    or

               (2)  when no Debt Securities of the affected series remain
                    outstanding under the Indenture;

o    to provide additional security for any Debt Securities;

o    to establish the form or terms of Debt Securities of any other series as
     permitted by the Indenture;

o    to provide for the authentication and delivery of bearer securities with or
     without coupons;

o    to evidence and provide for the acceptance of appointment by a separate or
     successor Trustee or co-trustee;

o    to provide for the procedures required for use of a noncertificated system
     of registration for the Debt Securities of all or any series;

o    to change any place where principal, premium, if any, and interest shall be
     payable, Debt Securities may be surrendered for registration of transfer or
     exchange and notices to us may be served;

o    to amend and restate the Indenture as originally executed and as amended
     from time to time, with additions, deletions and other changes that do not
     adversely affect the interests of the holders of Debt Securities of any
     series in any material respect;

o    to cure any ambiguity or inconsistency; or

o    after the Release Date, to amend the Indenture to eliminate any provisions
     related to the lien of the Indenture, collateral for the Debt Securities
     and Class A Bonds which are no longer applicable.

(Indenture, Section 1301.)

         The holders of at least a majority in aggregate principal amount of the
Debt Securities of all series then outstanding may waive compliance by us with
some restrictive provisions of the Indenture. (Indenture, Section 706.) The
holders of not less than a majority in principal amount of the outstanding Debt
Securities may waive any past default under the Indenture, except a default in
the payment of principal, premium, if any, or interest and certain covenants and
provisions of the Indenture that cannot be modified or be amended without the
consent of the holder of each outstanding Debt Security of any series affected.
(Indenture, Section 913.)

         The consent of the holders of a majority in aggregate principal amount
of the Debt Securities of all series then outstanding, considered as one class,
is required for all other modifications to the Indenture. However, if less than
all of the series of Debt Securities outstanding are directly affected by a
proposed supplemental indenture, then the consent only of the holders of a
majority in aggregate principal amount of the outstanding Debt Securities of all


                                       24



series that are directly affected, considered as one class, will be required. No
amendment or modification may without the consent of all the holders of the Debt
Securities of all series then outstanding:

o    change the stated maturity of the principal of, or any installment of
     principal of or interest on, any Debt Security, or reduce the principal
     amount of any Debt Security or its rate of interest or change the method of
     calculating that interest rate or reduce any premium payable upon
     redemption, or change the currency in which payments are made, or impair
     the right to institute suit for the enforcement of any payment on or after
     the stated maturity of any Debt Security;

o    create any lien ranking prior to the lien of the Indenture with respect to
     more than 10% of the collateral for the Debt Securities or, except as
     provided in the Indenture in connection with releases, the withdrawal of
     cash held by the Indenture Trustee and the Release Date, terminate the lien
     of the Indenture on more than 10% of the collateral for the Debt Securities
     or deprive any holder of the benefits of the security of the lien of the
     Indenture;

o    reduce the percentage in principal amount of the outstanding Debt
     Securities of any series the consent of the holders of which is required
     for any supplemental indenture or any waiver of compliance with a provision
     of the Indenture or any default thereunder and its consequences, or reduce
     the requirements for quorum or voting; or

o    modify some of the provisions of the Indenture relating to supplemental
     indentures, waivers of some covenants and waivers of past defaults with
     respect to the Debt Securities of any series.

         A supplemental indenture that changes the Indenture solely for the
benefit of one or more particular series of Debt Securities, or modifies the
rights of the holders of Debt Securities of one or more series, will not affect
the rights under the Indenture of the holders of the Debt Securities of any
other series. (Indenture, Section 1302.)

         The Indenture provides that Debt Securities owned by us or anyone else
required to make payment on the Debt Securities shall be disregarded and
considered not to be outstanding in determining whether the required holders
have given a request or consent.
(Indenture, Section 101.)

         We may fix in advance a record date to determine the required number of
holders entitled to give any request, demand, authorization, direction, notice,
consent, waiver or similar act of the holders, but we have no obligation to do
so. If we fix a record date, that request, demand, authorization, direction,
notice, consent, waiver or other act of the holders may be given before or after
that record date, but only the holders of record at the close of business on
that record date will be considered holders for the purposes of determining
whether holders of the required percentage of the outstanding Debt Securities
have authorized or agreed or consented to the request, demand, authorization,
direction, notice, consent, waiver or other act of the holders. For that
purpose, the outstanding Debt Securities will be computed as of the record date.

         Any request, demand, authorization, direction, notice, consent,
election, waiver or other act of a holder of any Debt Security will bind every
future holder of that Debt Security and the holder of every Debt Security issued
upon the registration of transfer of or in exchange for that Debt Security. A
transferee will also be bound by acts of the Indenture Trustee or us in reliance
thereon, whether or not notation of that action is made upon the Debt Security.
(Indenture, Section 106.)

VOTING OF CLASS A BONDS

         The Indenture provides that the Indenture Trustee will, as holder of
Class A Bonds delivered as the basis for the issuance of Debt Securities, attend
meetings of bondholders under the related Class A Mortgage, or deliver its proxy
in connection with those meetings, that relate to matters with respect to which
it, as a holder, is entitled to vote or consent. The Indenture provides that, so
long as no event of default under the Indenture has occurred and is continuing,
the Indenture Trustee will, as holder of the Class A Bonds, vote or consent
(without any consent or other action by the holders of the Debt Securities,
except as described in the proviso of paragraph (7) below) in favor of any
amendments or modifications to the Class A Mortgage of substantially the same
tenor and effect as follows:



                                       25



         (1)  to modify any Class A Mortgage to allow us to issue Class A Bonds
              up to 70% of the lower of (a) the fair value to us of the
              property subject to the lien of that Class A Mortgage as of a
              valuation date specified by us and (b) the cost of that property
              as of the valuation date;

         (2)  to make certain technical amendments to the Mortgage;

         (3)  to delete the net earnings test for the issuance of Class A Bonds
              and all references to it in any Class A Mortgage;

         (4)  to amend any Class A Mortgage so we may pay dividends and
              distributions to our common stockholders and repurchase our
              common stock so long as our shareholders' equity is positive;

         (5)  to amend any Class A Mortgage to permit an entity acquiring a
              substantial portion of the property subject to the lien of that
              Class A Mortgage to assume a pro rata share of the outstanding
              Class A Bonds issued under that Class A Mortgage based upon the
              net book value of that property acquired by that entity and to
              release us and our properties from any obligations or liens under
              that Class A Mortgage with respect to those assumed Class A
              Bonds, provided that the assumed Class A Bonds will be secured by
              a first lien on that acquired property to substantially the same
              extent and upon substantially the same terms as provided in that
              Class A Mortgage except for the substitution of the acquiring
              entity for us;

         (6)  to conform any provision of a Class A Mortgage in all material
              respects to the correlative provision of the Indenture, to add to
              a Class A Mortgage any provision not otherwise contained therein
              which conforms in all material respects to a provision contained
              in the Indenture, to delete from a Class A Mortgage any provision
              to which the Indenture contains no correlative provision and any
              combination of the foregoing; and/or

         (7)  with respect to any amendments or modifications to any Class A
              Mortgage other than those amendments or modifications referred to
              in clauses (1) through (6) above, vote all the Class A Bonds
              delivered under the Class A Mortgage, or consent with respect
              thereto, proportionately with the vote or consent of holders of
              all other Class A Bonds outstanding under the Class A Mortgage
              the holders of which are eligible to vote or consent, as
              evidenced by a certificate delivered by the trustee under the
              Class A Mortgage; provided, however, that the Indenture Trustee
              will not vote in favor of, or consent to, any amendment or
              modification of a Class A Mortgage which, if it were an amendment
              or modification of the Indenture, would require the consent of
              holders of Debt Securities as described under "Modification and
              Waiver," without the prior consent of holders of Debt Securities
              which would be required for an amendment or modification of the
              Indenture. (Indenture, Section 1705.)

         As described more fully in DESCRIPTION OF THE FIRST MORTGAGE BONDS -
"Modification" below, we may make amendments to, or eliminate some of the
covenants in, the Mortgage with the consent of the holders of 60% of the
outstanding First Mortgage Bonds issued under the Mortgage. A holder of Debt
Securities would no longer benefit from the covenants contained in the Mortgage
should the Indenture Trustee vote these First Mortgage Bonds to amend or
eliminate the covenants as described above.

RESIGNATION OF A TRUSTEE

         The Indenture Trustee may resign at any time by giving written notice
to us or may be removed at any time by an act of the holders of a majority in
principal amount of all series of Debt Securities then outstanding delivered to
the Indenture Trustee and us. No resignation or removal of the Indenture Trustee
and no appointment of a successor trustee will be effective until the acceptance
of appointment by a successor trustee. So long as no event of default or event
which, after notice or lapse of time, or both, would become an event of default
has occurred and is continuing and except with respect to a trustee appointed by
act of the holders, if we have delivered to the Indenture Trustee a resolution
of our Board of Directors appointing a successor trustee and the successor has
accepted the appointment in accordance with the terms of the Indenture, the
Indenture Trustee will be deemed to have resigned and the successor will be


                                       26



deemed to have been appointed as trustee in accordance with the Indenture.
(Indenture, Section 1010.)

NOTICES

         Notices to holders of Debt Securities will be given by mail to the
addresses of the holders as they may appear in the security register for Debt
Securities. (Indenture, Section 108.)

TITLE

         We, the Indenture Trustee, and any of our or the Indenture Trustee's
agents, may treat the person in whose name Debt Securities are registered as the
absolute owner thereof, whether or not the Debt Securities may be overdue, for
the purpose of making payments and for all other purposes irrespective of notice
to the contrary. (Indenture, Section 308.)

GOVERNING LAW

         The Indenture is, and the Debt Securities will be, governed by, and
construed in accordance with, the laws of the state of New York except where
otherwise required by law. (Indenture, Section 114.)

INFORMATION ABOUT THE INDENTURE TRUSTEE

         The Indenture Trustee will be The Bank of New York. In addition to
acting as Indenture Trustee, The Bank of New York also acts as the Mortgage
Trustee. The Bank of New York also acts, and may act, as trustee under various
other of our and our affiliates' indentures, trusts and guarantees. We and our
affiliates maintain deposit accounts and credit and liquidity facilities and
conduct other banking transactions with the trustee and its affiliates in the
ordinary course of our respective businesses.


                     DESCRIPTION OF THE FIRST MORTGAGE BONDS

         As discussed above under DESCRIPTION OF THE DEBT SECURITIES -
"Security" and "Discharge of Lien; Release Date," the Debt Securities will be
issued on the basis of, and primarily secured by, one or more series of first
mortgage bonds issued by us under the Indenture of Mortgage, dated as of May 1,
1939, made by and between MDU (formerly Montana-Dakota Utilities Co.) and The
New York Trust Company (The Bank of New York, as successor Corporate Trustee
(the "Mortgage Trustee")) and all indentures supplemental thereto (including the
(Forty-Fifth) Supplemental Indenture, dated as of April 21, 1992, which
contains, in Part II thereof, a Restatement of Indenture) (collectively, the
"Mortgage") and delivered by us to the Indenture Trustee. In this prospectus we
refer to all first mortgage bonds issued or to be issued under the Mortgage,
including the first mortgage bonds to be delivered to the Indenture Trustee, as,
collectively, the "First Mortgage Bonds."

         We will issue First Mortgage Bonds in an aggregate principal amount
equal to the aggregate principal amount of the Debt Securities, in one or more
series, under the Mortgage, in fully registered form. First Mortgage Bonds are,
or will be, secured by a first mortgage lien on the Mortgaged Property as
described below under "Security and Priority." All First Mortgage Bonds are
equally secured and rank equally with respect to each other.

         The Mortgage is filed as an exhibit to the registration statement. This
section of the prospectus contains a summary of all material provisions of the
Mortgage. The Mortgage and its associated documents contain the full legal text
of the matters described in this section. Because this section is a summary, it
does not describe every aspect of the First Mortgage Bonds or the Mortgage. This
summary is subject to and qualified in its entirety by reference to all the
provisions of the Mortgage, including definitions of terms used in the Mortgage,
which may be used in this document without definition. We also include
references in parentheses to sections of the Mortgage. Whenever we refer to
particular sections or defined terms of the Mortgage in this prospectus or in a
prospectus supplement, the references are to the Restatement of Indenture
described above, and all amendments or modifications to the Restatement of
Indenture, if any; and the sections or defined terms are incorporated by
reference into this document or in the prospectus supplement. This summary also


                                       27



is subject to and qualified by reference to the description of the particular
terms of the First Mortgage Bonds described in the applicable prospectus
supplement or supplements. The Mortgage has been qualified under the Trust
Indenture Act, and you should refer to the Trust Indenture Act for provisions
that apply to the First Mortgage Bonds.

SECURITY AND PRIORITY

         In the opinion of our General Counsel, the First Mortgage Bonds now or
hereafter issued will be secured, together with all other First Mortgage Bonds,
by a valid and direct first mortgage lien on substantially all of the fixed
properties owned and all franchises held by us immediately prior to July 1,
2000, together with improvements, extensions and additions to, and renewals,
replacements and substitutions of or for, any part or parts of these properties,
other than property excepted or released from the Mortgage (as described below),
subject to the lien of taxes for the current year and the lien of taxes and
assessments not yet delinquent and to specified exceptions and reservations
which do not, in the opinion of counsel, materially affect our title to or right
to use the properties. This property, other than property excepted and released
from the Mortgage, is sometimes referred to as the "Mortgaged Property." There
are excepted from Mortgaged Property all properties acquired by us on or after
July 1, 2000, including the properties acquired in the merger with Great Plains
Energy Corp. and Great Plains Natural Gas Co. (which include all properties of
the Company located in the state of Minnesota and all gas distribution
properties located in the southeastern part of North Dakota), but excluding
improvements, extensions and additions to, and renewals, replacements and
substitutions of or for, any part or parts of the Mortgaged Property owned by us
immediately prior to July 1, 2000 unless otherwise excepted from the lien of the
Mortgage. There are also excepted from Mortgaged Property all cash, receivables
and securities (including the capital stock of Centennial Energy Holdings, Inc.,
WBI Holdings, Inc., Knife River Corporation, Utility Services, Inc., Centennial
Energy Resources LLC, Centennial Holdings Capital LLC, Centennial Energy
Resources International Inc, Fidelity Exploration & Production Company and any
other subsidiaries); some contracts; merchandise, appliances, materials or
supplies; electric energy, gas, steam and other products; and automobiles,
tractors, ships, railroad cars and aircraft and various other transportation
equipment. The property of subsidiaries, including Centennial Energy Holdings,
Inc., WBI Holdings, Inc., Knife River Corporation, Utility Services, Inc.,
Centennial Energy Resources LLC, Centennial Holdings Capital LLC, Centennial
Energy Resources International Inc, Fidelity Exploration & Production Company
and any other subsidiaries), is not subject to the lien of the Mortgage. We have
released and transferred certain properties from the lien of the Mortgage since
July 1, 2000, and may release additional property subject to the lien of the
Mortgage against various credits, including:

         o    cash deposited with the Mortgage Trustee,

         o    the principal amount of bonds or other obligations deposited with
              the Mortgage Trustee secured by a purchase money mortgage on the
              property released up to 70% of the fair value to us of that
              property, or

         o    the fair value in cash of bonds or other obligations of municipal
              corporations or other governmental subdivisions possessing taxing
              power.

We may withdraw cash held by the Mortgage Trustee against various credits,
including

         o    the principal amount of refundable bonds not previously used
              under the Mortgage,

         o    70% of the net bondable value of property additions, or

         o    the lesser of cost or fair value to us of property which is
              already subject to the lien of the Mortgage, but which has not
              yet been used as a credit under any provisions of the Mortgage.

Property not used as the basis for the issuance of First Mortgage Bonds or
otherwise as a credit under the Mortgage may in effect be released without
substitution of equivalent property.

         The Mortgage provides that after-acquired properties (other than the
excepted property and released property described above) that are improvements,
extensions or additions to, or renewals, replacements or substitutions of or
for, any part or parts of the Mortgaged Property will be subject to the lien of
the Mortgage. (Mortgage, Forty-Ninth Supplemental Indenture.) We also may elect


                                       28



to subject additional property to the lien of the Mortgage by amending the
Mortgage.

ISSUANCE OF ADDITIONAL FIRST MORTGAGE BONDS

         We may issue additional First Mortgage Bonds ranking equally with
outstanding First Mortgage Bonds in a principal amount equal to:

               (1)  70% of the net bondable value of property additions we
                    acquire;

               (2)  the amount of cash deposited with the Mortgage Trustee; and

               (3)  the amount of refundable First Mortgage Bonds surrendered to
                    the Mortgage Trustee.

(Mortgage, Sections 3.04 through 3.06.)

         The First Mortgage Bonds will be issued against property additions,
refunded First Mortgage Bonds and/or the deposit of cash. On March 31, 2003, we
had approximately $170 million of available Property Additions and $163 million
of refunded First Mortgage Bonds. See the discussion above under "Security and
Priority."

         With some exceptions in the case of (3) above, additional First
Mortgage Bonds may be issued only if our net earnings available for interest
after depletion, as defined in the Mortgage, for any twelve consecutive calendar
months within the fifteen calendar months immediately preceding the month in
which the application for the additional First Mortgage Bonds is made, are in
the aggregate equal to at least two times the amount of the annual stated
interest charges on all First Mortgage Bonds thereafter to be outstanding, and
on all permitted equal or prior lien debt, if any. (Mortgage, Sections 1.01 and
3.03.) For the twelve months ended March 31, 2003, our net earnings available
for interest after depletion were $77 million or 7.9 times the annual stated
interest charges on all First Mortgage Bonds and permitted equal or prior lien
debt outstanding on that date, which would have permitted us to issue
approximately $333 million of additional First Mortgage Bonds.

         Property available for use as property additions includes property
useful in the energy business in any form (other than gas but including gas
distribution property) and water and steam heat property. The property may be
located anywhere in the United States of America or its coastal waters and may
also include space satellites (including solar power satellites), space stations
and other analogous facilities. (Mortgage, Section 1.01.)

         Any additional First Mortgage Bonds issued by us would not be included
as Debt Securities covered by this prospectus or the registration statement that
this prospectus is included within.

DIVIDEND RESTRICTIONS

         So long as any of the First Mortgage Bonds are outstanding, we may
declare and pay dividends in cash or property on our common stock only out of
Surplus, as defined in the Mortgage, or out of net profits for the fiscal year
or the preceding fiscal year. However, we may not pay dividends out of net
profits if the Capital of the Company, as defined in the Mortgage, has been
diminished to a specified extent. (Mortgage, Section 2.01.)

MAINTENANCE AND DEPRECIATION PROVISIONS

         We are required to make expenditures necessary to maintain the
mortgaged property in good repair, except that we may abandon any property, and
to make provisions for depreciation and for depletion of depletable fixed assets
in accordance with good accounting practices and in accordance with any
applicable rules of any regulatory authority having jurisdiction. (Mortgage,
Section 6.06.)

MODIFICATION

         Modifications of the terms of the Mortgage may be made with our consent
by an affirmative vote of at least 60% in principal amount of outstanding First


                                       29



Mortgage Bonds and of at least 60% in principal amount of outstanding First
Mortgage Bonds of any series especially affected by the modification; but no
modification may be made which will affect the terms of payment of the principal
at maturity of, or interest on, any First Mortgage Bond. (Mortgage, Article XV.)

VOTING OF FIRST MORTGAGE BONDS HELD BY THE INDENTURE TRUSTEE

         The Indenture Trustee will, as holder of the First Mortgage Bonds,
attend meetings of bondholders under the Mortgage, or deliver its proxy in
connection with those meetings, as to matters with respect to which it is
entitled to vote or consent. See DESCRIPTION OF THE DEBT SECURITIES - "Voting of
Class A Bonds."

DEFAULTS AND NOTICE OF DEFAULTS

         "Events of default" include the failure to pay principal, failure for
30 days to pay interest or to make any required deposit in any fund for the
purchase or redemption of First Mortgage Bonds (including any sinking fund or
improvement and sinking fund), failure for 90 days after written notice to
perform any other covenant, and various events in bankruptcy or insolvency.
(Mortgage, Article IX.)

         The Trustees under the Mortgage are required to give notice to
Bondholders of any continuing event of default known to them, but other than for
a default in the payment of principal or interest or a sinking fund installment,
the Trustees may withhold notice if the responsible officers of the Corporate
Trustee in good faith determine that the withholding is in the interests of the
Bondholders. (Mortgage, Section 13.03.)

SATISFACTION AND DISCHARGE

         Once we make due provision for the payment of all of the First Mortgage
Bonds and paying all other sums due under the Mortgage, the Mortgage will cease
to be of further effect and may be discharged. (Mortgage, Article XVI.)

ANNUAL REPORT TO THE MORTGAGE TRUSTEE

         We must give the Mortgage Trustee an annual statement as to whether or
not we have fulfilled our obligations under the Mortgage throughout the
preceding calendar year.


                         DESCRIPTION OF THE COMMON STOCK

COMMON STOCK - GENERAL

         The following is a description of all material attributes of our common
stock. This description is not complete, and we qualify it by referring to the
laws of the state of Delaware and our restated certificate of incorporation,
amended bylaws and Mortgage. The restated certificate of incorporation, amended
bylaws and Mortgage are exhibits 3(a), 3(b) and 4(a), respectively, to the
registration statement that this prospectus is included within and all of these
documents are incorporated into this prospectus by reference. We also refer you
to the rights agreement, dated as of November 12, 1998, between us and Norwest
Bank Minnesota, NA (now, Wells Fargo Bank Minnesota, N.A.), as rights agent,
that we incorporate into this document by reference to Exhibit 4(c) to the
registration statement that this prospectus is included within.

         Our restated certificate of incorporation authorizes us to issue
252,000,000 shares of stock, divided into four classes:

o    500,000 shares of preferred stock, $100 par value;

o    1,000,000 shares of preferred stock A, without par value;

o    500,000 shares of preference stock, without par value; and



                                       30



o    250,000,000 shares of common stock, $1.00 par value.

DIVIDEND RIGHTS

         Under our restated certificate of incorporation, we may declare and pay
dividends on our common stock, out of surplus or net profits, only if we have
paid or provided for full cumulative dividends on all outstanding shares of
preferred and preference stock. As of March 31, 2003, we had no preference stock
outstanding.

         In addition to these provisions, our first mortgage bond indenture
includes a covenant generally to the effect that we may declare and pay
dividends in cash or property on our common stock only either (1) out of
"surplus" or (2) in case there is no "surplus," out of net profits for the
fiscal year in which the dividend is declared and/or the preceding fiscal year.
For purposes of this test, "surplus" means the excess of our net assets over our
"capital"; and "capital" means that part of the consideration received by us for
any of our shares of common stock which has been determined to be "capital."

VOTING RIGHTS

         Our common stock has one vote per share. The holders of our common
stock are entitled to vote on all matters to be voted on by stockholders. The
holders of our common stock do not have cumulative voting rights.

         The holders of our preferred stock, preferred stock A and preference
stock do not have the right to vote, except as our board of directors
establishes or as provided in our restated certificate of incorporation or
bylaws or as determined by state law.

         Our restated certificate of incorporation gives the holders of our
preferred stock, preferred stock A or the preference stock the right to vote if
dividends are unpaid, in whole or in part, on their shares for one year. The
holders have one vote per share until we pay the dividend arrearage, declare
dividends for the current dividend period and set aside the funds to pay the
current dividends. In addition, the holders of some series of our preferred
stock and preferred stock A, and/or the holders of our preference stock, must
approve amendments to the restated certificate of incorporation in some
instances.

LIQUIDATION RIGHTS

         If we were to liquidate, the holders of the preferred stock, preferred
stock A and the preference stock have the right to receive specified amounts, as
set forth in our restated certificate of incorporation, before we can make any
payments to the holders of our common stock. After the preferred and preference
stock payments are made, the holders of our common stock are entitled to share
in all of our remaining assets available for distribution to stockholders.

OTHER RIGHTS

         Our common stock is not liable to further calls or assessment. The
holders of our common stock have no preemptive rights. Our common stock cannot
be redeemed, and it does not have any conversion rights or sinking fund
provisions.

EFFECTS ON OUR COMMON STOCK IF WE ISSUE PREFERRED OR PREFERENCE STOCK

         Our board of directors has the authority, without further action by the
stockholders, to issue up to 500,000 shares of preferred stock, 1,000,000 shares
of preferred stock A and 500,000 shares of preference stock, each in one or more
series. Our board of directors has the authority to determine the terms of each
series of any preferred or preference stock, within the limits of the restated
certificate of incorporation and the laws of the state of Delaware. These terms
include the number of shares in a series, dividend rights, liquidation
preferences, terms of redemption, conversion rights and voting rights.

         If we issue any preferred or preference stock, we may negatively affect
the holders of our common stock. These possible negative effects include
diluting the voting power of shares of our common stock and affecting the market


                                       31



price of our common stock. In addition, the ability of our board of directors to
issue preferred or preference stock may delay or prevent a change in control of
MDU Resources.

         As of March 31, 2003, we had 163,000 shares of preferred stock
outstanding, and we have reserved 125,000 shares of Series B preference stock
for issuance in connection with our rights plan.

PROVISIONS OF OUR RESTATED CERTIFICATE OF INCORPORATION AND OUR BYLAWS THAT
COULD DELAY OR PREVENT A CHANGE IN CONTROL

         Our restated certificate of incorporation and bylaws contain provisions
which will make it difficult to obtain control of MDU Resources if our board of
directors does not approve the transaction. The provisions include the
following:

         PROVISIONS RELATING TO OUR BOARD OF DIRECTORS

             CLASSIFIED BOARD

         We have divided the members of our board of directors into three
classes as nearly equal in number as may be. Directors in each class are elected
for a three-year term.

         This classification of our board of directors may prevent stockholders
from changing the membership of the entire board of directors in a relatively
short period of time. At least two annual meetings, instead of one, generally
will be required to change the majority of directors. The classified board
provisions could have the effect of prolonging the time required for a
stockholder with significant voting power to gain majority representation on our
board of directors. Where majority or supermajority board of directors approval
is necessary for a transaction, like in the case of an interested stockholder
business combination, the inability immediately to gain majority representation
on the board of directors could discourage takeovers and tender offers.

             NUMBER OF DIRECTORS, VACANCIES, REMOVAL OF DIRECTORS

         Our restated certificate of incorporation provides that our board of
directors will have at least six and at most 15 directors. Two-thirds of the
continuing directors decide the exact number of directors at a given time. Our
board fills any new directorships it creates and any vacancies.

         Our directors may be removed only for cause and then only by a majority
of the shares entitled to vote.

MEETINGS OF STOCKHOLDERS

             NO CUMULATIVE VOTING

         Our restated certificate of incorporation does not provide for
cumulative voting.

             ADVANCE NOTICE PROVIsIONS

         Our bylaws require that for a stockholder to nominate a director or
bring other business before an annual meeting, the stockholder must give notice
not less than 120 days prior to the date corresponding to the date on which we
first mailed our proxy materials for the prior year's annual meeting.

         Our restated certificate of incorporation prevents stockholders from
calling a special meeting. In addition, our restated certificate of
incorporation provides that stockholder action may be taken only at a
stockholders' meeting.

AMENDMENT OF RESTATED CERTIFICATE OF INCORPORATION

         Our restated certificate of incorporation requires the affirmative vote
of 80% of the common stock entitled to vote in order to amend Articles Twelfth,
Thirteenth, Fourteenth, Fifteenth and Sixteenth of our restated certificate of


                                       32



incorporation, unless two-thirds of the continuing directors approve the
amendment. Article Twelfth of our restated certificate of incorporation
specifies fair price and other requirements applicable to a business combination
involving an interested stockholder (e.g., a stockholder who is our affiliate).
Article Thirteenth of our restated certificate of incorporation contains
provisions relating to our board of directors, including provisions establishing
a classified board. Article Fourteenth of our restated certificate of
incorporation expressly permits our board of directors to consider the factors
described below under "Provisions Relating to the Authorization of Business
Combinations" in determining whether or not to approve some types of business
combinations. Article Fifteenth of our restated certificate of incorporation
contains the requirement described in the first sentence of this paragraph that
80% of the common stock entitled to vote must vote in favor of an amendment to
the articles specified above unless two-thirds of the continuing directors
approve the amendment. Finally, Article Sixteenth of the restated certificate of
incorporation prohibits stockholders from taking action by written consent and
describes the persons who may call special meetings of our stockholders.

PROVISIONS RELATING TO THE AUTHORIZATION OF BUSINESS COMBINATIONS

         Our restated certificate of incorporation requires the affirmative vote
of 80% of the common stock entitled to vote for directors in order to authorize
business combinations with interested stockholders. Any business combination
must also meet specified fair price and procedural requirements. However, if
two-thirds of our continuing directors approve the business combination, then
the vote of 80% of the common stock and the fair price provisions will not be
required.

         There is also a provision in our restated certificate of incorporation
permitting our board of directors to consider the following factors in
determining whether or not to approve some types of business combinations:

     o   The consideration to be received by us or our stockholders in
         connection with the business combination in relation not only to the
         then current market price for our outstanding capital stock, but also
         to the market price for our capital stock over a period of years, the
         estimated price that might be achieved in a negotiated sale of us as a
         whole or in part through orderly liquidation, the premiums over market
         price for the securities of other corporations in similar
         transactions, current political, economic and other factors bearing on
         securities prices and our financial condition, future prospects and
         future value as an independent corporation;

     o   The character, integrity and business philosophy of the other party or
         parties to the business combination transaction and the management of
         that party or those parties;

     o   The business and financial conditions and earnings prospects of the
         other party or parties to the business combination transaction,
         including, but not limited to, debt service and other existing or
         likely financial obligations of that party or those parties, the
         intention of the other party or parties to the business combination
         transaction regarding the use of our assets to finance the
         acquisition, and the possible effect of the conditions upon us and our
         subsidiaries and the other elements of the communities in which we and
         our subsidiaries operate or are located;

     o   The projected social, legal and economic effects of the proposed
         action or transaction upon us or our subsidiaries, employees,
         suppliers, customers and others having similar relationships with us,
         and the communities in which we and our subsidiaries do business;

     o   The general desirability of our continuance as an independent entity;
         and

     o   Such other factors as the continuing directors may deem relevant.

PROVISIONS OF DELAWARE LAW THAT COULD DELAY OR PREVENT A CHANGE IN CONTROL

         We are subject to the provisions of Section 203 of the General
Corporation Law of Delaware. With some exceptions, this law prohibits us from
engaging in some types of business combinations with a person who owns 15% or
more of our outstanding voting stock for a three-year period after that person
acquires the stock. This prohibition does not apply if our board of directors
approved of the business combination or the acquisition of our stock before the


                                       33



person acquired 15% of the stock. A business combination includes mergers,
consolidations, stock sales, asset sales and other transactions resulting in a
financial benefit to the interested stockholder.

TRANSFER AGENT; REGISTRAR

         The transfer agent and registrar for our common stock is Wells Fargo
Bank Minnesota, N.A., Saint Paul, Minnesota.


               DESCRIPTION OF THE PREFERENCE SHARE PURCHASE RIGHTS


GENERAL

         On November 12, 1998, the board of directors declared a dividend of one
preference share purchase right for each outstanding share of common stock, par
value $1.00 per share. The dividend was paid on December 1, 1998 to the
stockholders of record on that date.

         Our board of directors has adopted a rights agreement to protect our
stockholders from coercive or otherwise unfair takeover tactics. In general
terms, it works by imposing a significant penalty upon any person or group which
acquires 15% or more of our outstanding common stock without the approval of the
board of directors. The rights agreement should not interfere with any merger or
other business combination approved by our board of directors.

         For those interested in the specific terms of the rights agreement
between us and Wells Fargo Bank Minnesota, N.A., as the rights agent, dated as
of November 12, 1998, we are providing the following summary description of all
of the material terms of the rights agreement. Please note, however, that this
description is only a summary, and is not complete, and should be read together
with the entire rights agreement, a copy of which is available from us free of
charge.

THE RIGHTS

         Our board of directors authorized the issuance of a preference share
purchase right with respect to each issued and outstanding share of our common
stock on December 1, 1998. The preference share purchase rights will initially
trade with, and will be inseparable from, the common stock. The preference share
purchase rights are evidenced only by certificates that represent shares of
common stock. New preference share purchase rights will accompany any new shares
of common stock that we issue after December 1, 1998 until the distribution date
described below.

EXERCISE PRICE

         Each preference share purchase right will allow its holder to purchase
from us one one-thousandth of a share of Series B preference stock for $125,
once the preference share purchase rights become exercisable. This portion of a
share of Series B preference stock will give the stockholder approximately the
same dividend and liquidation rights as would one share of common stock. Prior
to exercise, the preference share purchase right does not give its holder any
dividend, voting, or liquidation rights.

EXERCISABILITY

          The preference share purchase rights will not be exercisable until:

o    10 days after the public announcement that a person or group has become an
     "acquiring person" by obtaining beneficial ownership of 15% or more of MDU
     Resources' outstanding common stock, or, if earlier,



                                       34



o    10 business days (or a later date determined by our board of directors
     before any person or group becomes an acquiring person) after a person or
     group begins a tender or exchange offer which, if consummated, would result
     in that person or group becoming an acquiring person.

         We refer to the date when the preference share purchase rights become
exercisable as the "distribution date." Until that date, the common stock
certificates will also evidence the preference share purchase rights, and any
transfer of shares of common stock will constitute a transfer of preference
share purchase rights. After that date, the preference share purchase rights
will separate from the common stock and be evidenced by book-entry credits or by
preference share purchase rights certificates that we would mail to all eligible
holders of common stock. Any preference share purchase rights held by an
acquiring person are void and may not be exercised.

         Our board of directors may reduce the threshold at which a person or
group becomes an acquiring person from 15% to not less than 10% of the
outstanding common stock.

CONSEQUENCES OF A PERSON OR GROUP BECOMING AN ACQUIRING PERSON

         Flip In. If a person or group becomes an acquiring person, all holders
of preference share purchase rights except the acquiring person may, for $125,
purchase shares of our common stock with a market value of $250, based on the
market price of the common stock prior to the acquisition.

         Flip Over. If we are later acquired in a merger or similar transaction
after the "preference share purchase rights distribution date," all holders of
preference share purchase rights except the acquiring person may, for $125,
purchase shares of the acquiring corporation with a market value of $250, based
on the market price of the acquiring corporation's stock prior to the merger.

PREFERENCE SHARE PROVISIONS

         Each one one-thousandth of a share of Series B preference stock, if
issued:

o    will not be redeemable.

o    will entitle holders to quarterly dividend payments of $.001 per share, or
     an amount equal to the dividend paid on one share of common stock,
     whichever is greater.

o    will entitle holders upon liquidation either to receive $1.00 per share or
     an amount equal to the payment made on one share of common stock, whichever
     is greater.

o    will have no voting power, except as otherwise provided by Delaware law or
     our restated certificate of incorporation.

o    will entitle holders to a per share payment equal to the payment made on
     one share of common stock, if shares of our common stock are exchanged via
     merger, consolidation, or a similar transaction.

The value of one one-thousandth interest in a share of Series B preference stock
should approximate the value of one share of common stock.

EXPIRATION

         The preference share purchase rights will expire on December 31, 2008.

REDEMPTION

         Our board of directors may redeem the preference share purchase rights
for $.01 per preference share purchase right at any time before any person or
group becomes an acquiring person. If the board of directors redeems any
preference share purchase rights, it must redeem all of the preference share
purchase rights. Once the preference share purchase rights are redeemed, the


                                       35



only right of the holders of preference share purchase rights will be to receive
the redemption price of $.01 per preference share purchase right. The redemption
price will be adjusted if we have a stock split of, or stock dividends on, our
common stock.

EXCHANGE

         After a person or group becomes an acquiring person, but before an
acquiring person owns 50% or more of our outstanding common stock, our board of
directors may extinguish the preference share purchase rights by exchanging one
share of common stock or an equivalent security for each preference share
purchase right, other than preference share purchase rights held by the
acquiring person.

ANTI-DILUTION PROVISIONS

         Our board of directors may adjust the purchase price of a share of
Series B preference stock, the number of shares of Series B preference stock
issuable and the number of outstanding preference share purchase rights to
prevent dilution that may occur from a stock dividend, a stock split, a
reclassification of the Series B preference stock or common stock. No
adjustments to the exercise price of less than 1% will be made.

AMENDMENTS

         The terms of the rights agreement may be amended by our board of
directors without the consent of the holders of the preference share purchase
rights. However, our board may not amend the rights agreement to lower the
threshold at which a person or group becomes an acquiring person to below 10% of
our outstanding common stock. In addition, our board may not cause a person or
group to become an acquiring person by lowering this threshold below the
percentage interest that the person or group already owns. After a person or
group becomes an acquiring person, the board may not amend the agreement in a
way that adversely affects holders of the preference share purchase rights.


                              PLAN OF DISTRIBUTION

         We may sell the securities offered by this prospectus in one or more of
the following ways from time to time: (i) to underwriters for resale to the
public or to institutional investors; (ii) directly to institutional investors;
or (iii) through agents to the public or to institutional investors. The
prospectus supplement with respect to the securities being sold will set forth
the terms of the offering of those securities, including the name or names of
any underwriters or agents, the purchase price of the securities and the net
proceeds to us from the sale, any underwriting discounts or agency fees and
other items constituting underwriters' or agents' compensation, any initial
public offering price, and any discounts or concessions allowed or reallowed or
paid to dealers.

         If underwriters participate in the sale, the securities will be
acquired by the underwriters for their own account and may be resold from time
to time in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of sale.

         If the securities are sold by agents, commissions payable by us to
those agents will be set forth in a related prospectus supplement. Unless
otherwise indicated in a prospectus supplement, any agent will be acting on a
reasonable efforts basis for the period of its appointment.

         Unless otherwise set forth in the prospectus supplement, the
obligations of the underwriters to purchase the securities will be subject to
conditions precedent and the underwriters will be obligated to purchase all the
securities being offered if any are purchased.

         We may make sales of our common stock to or through one or more
underwriters or agents in at-the-market offerings, we will do so pursuant to the
terms of a distribution agreement between us and the underwriters or agents. If
we engage in at-the-market sales pursuant to a distribution agreement, we will
issue and sell shares of our common stock to or through one or more underwriters
or agents, which may act on an agency basis or on a principal basis. During the
term of any such distribution agreement, we may sell shares on a daily basis in


                                       36



exchange transactions or otherwise as we agree with the underwriters or agent.
The distribution agreement may provide that any shares of our common stock sold
will be sold at prices related to the then prevailing market prices for our
securities. Therefore, exact figures regarding net proceeds to us or commissions
to be paid are impossible to determine and will be described in a prospectus
supplement. Pursuant to the terms of the distribution agreement, we also may
agree to sell, and the relevant underwriters or dealers may agree to solicit
offers to purchase, blocks of our common stock. The terms of each such
distribution agreement will be set forth in more detail in a prospectus
supplement to this prospectus. To the extent that any named underwriter or agent
acts as principal pursuant to the terms of a distribution agreement, or if we
offer to sell shares of our common stock through another broker-dealer acting as
underwriter, then such named underwriter may engage in certain transactions that
stabilize, maintain or otherwise affect the price of our common stock. We will
describe any such activities in the prospectus supplement relating to the
transaction. To the extent that any named broker dealer or agent acts as agent
on a best efforts basis pursuant to the terms of a distribution agreement, such
broker dealer or agent will not engage in any such stabilization transactions.

         Underwriters and agents may be entitled under agreements entered into
with us to indemnification against securities civil liabilities, including
liabilities under the Securities Act of 1933. Underwriters and agents may engage
in transactions with, or perform services for, us in the ordinary course of
business.

         Each series of securities offered by this prospectus will be a new
issue and, except for the common stock, which is listed on the New York Stock
Exchange and the Pacific Exchange, will have no established trading market. We
may elect to list any series of new securities on an exchange, or in the case of
the common stock, on any additional exchange, but unless otherwise indicated in
the prospectus supplement, we have no obligation to cause any securities to be
so listed. Any underwriters that purchase securities for public offering and
sale may make a market in the securities, but such underwriters will not be
obligated to do so and may discontinue any market making at any time without
notice. We make no assurance as to the liquidity of, or the trading markets for,
any securities.


                                     EXPERTS

         The consolidated financial statements and consolidated financial
statement schedule incorporated by reference from our Annual Report on Form 10-K
for the year ended December 31, 2002, have been audited by Deloitte & Touche
LLP, independent auditors, as stated in their reports which are incorporated
herein by reference (which express an unqualified opinion and include an
explanatory paragraph relating to the application of certain procedures relating
to certain other disclosures and reclassifications of financial statement
amounts related to the 2001 and 2000 consolidated financial statements that were
audited by other auditors for which Deloitte & Touche LLP has expressed no
opinion or other form of assurance other than with respect to such disclosures
and reclassifications), and have been so incorporated in reliance upon the
reports of such firm given upon their authority as experts in accounting and
auditing.

         Our consolidated financial statements and schedule as of December 31,
2001 for the years ended December 31, 2001 and 2000 incorporated in this
prospectus by reference from our Annual Report on Form 10-K for the year ended
December 31, 2002 were audited by Arthur Andersen LLP, independent public
accountants, as indicated in their report with respect thereto (which expresses
an unqualified opinion and includes an explanatory paragraph relating to the
adoption of a new accounting principle), and have been so incorporated in
reliance upon the report and upon the authority of that firm as experts in
accounting and auditing in giving the report. On February 14, 2002, we dismissed
Arthur Andersen LLP as our independent public accounting firm, and on March 25,
2002, we hired Deloitte & Touche LLP as our independent auditors for the 2002
fiscal year. Since that time, Arthur Andersen LLP was convicted on federal
charges of obstruction of justice, and in August 2002, Arthur Andersen LLP
ceased performing auditing services worldwide. These events may materially and
adversely affect the ability of Arthur Andersen LLP to satisfy all of their
existing and future obligations, including claims under the federal securities
laws. Accordingly, purchasers of our securities may be limited in their ability
to recover damages from Arthur Andersen LLP for any claims that may arise out of
Arthur Andersen LLP's audit of our financial statements. In addition, we were
not able to obtain the consent of Arthur Andersen LLP as required by Section 7
of the Securities Act to the incorporation by reference of their report on the
audited financial statements into the registration statement. As a result of


                                       37



Arthur Andersen LLP not having provided a consent, the ability of purchasers of
our securities to assert claims and seek remedies against Arthur Andersen LLP
may be limited with respect to their report, particularly those remedies arising
under Section 11 of the Securities Act.


                                 LEGAL OPINIONS

         The validity of the securities has been passed upon for us by Lester H.
Loble, II, Esq., our General Counsel, and also by Thelen Reid & Priest LLP, 875
Third Avenue, New York, New York 10022.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Our Bylaws include the following provision:

               7.07 INDEMNIFICATION OF OFFICERS, DIRECTORS, EMPLOYEES AND
                    AGENTS; INSURANCE.

         (a)  The Corporation shall indemnify any person who was or is a party
              or is threatened to be made a party to any threatened, pending or
              completed action, suit or proceeding, whether civil, criminal,
              administrative or investigative (other than an action by or in
              the right of the Corporation) by reason of the fact that such
              person is or was a director, officer, employee or agent of the
              Corporation, or is or was serving at the request of the
              Corporation as a director, officer, employee or agent of another
              corporation, partnership, joint venture, trust or other
              enterprise, against expenses (including attorneys' fees),
              judgments, fines and amounts paid in settlement actually and
              reasonably incurred by such person in connection with such
              action, suit or proceeding if such person acted in good faith and
              in a manner such person reasonably believed to be in or not
              opposed to the best interests of the Corporation, and, with
              respect to any criminal action or proceeding, had no reasonable
              cause to believe such person's conduct was unlawful. The
              termination of any action, suit or proceeding by judgment, order,
              settlement, conviction, or upon a plea of nolo contendere or its
              equivalent, shall not, of itself, create a presumption that the
              person did not act in good faith and in a manner which such
              person reasonably believed to be in or not opposed to the best
              interest of the Corporation, and, with respect to any criminal
              action or proceeding, had reasonable cause to believe that such
              person's conduct was unlawful.

         (b)  The Corporation shall indemnify any person who was or is a party
              or is threatened to be made a party to any threatened, pending or
              completed action or suit by or in the right of the Corporation to
              procure a judgment in its favor by reason of the fact that such
              person is or was a director, officer, employee or agent of the
              Corporation, or is or was serving at the request of the
              Corporation as a director, officer, employee or agent of another
              corporation, partnership, joint venture, trust or other
              enterprise against expenses (including attorneys' fees) actually
              and reasonably incurred by such person in connection with the
              defense or settlement of such action or suit if such person acted
              in good faith and in a manner such person reasonably believed to
              be in or not opposed to the best interests of the Corporation and
              except that no indemnification shall be made in respect of any
              claim, issue or matter as to which such person shall have been
              adjudged to be liable to the Corporation, unless and only to the
              extent that the Court of Chancery or the court in which such
              action or suit was brought, shall determine upon application
              that, despite the adjudication of liability but in view of all
              circumstances of the case, such person is fairly and reasonably


                                      II-1



              entitled to indemnity for such expenses which the Court of
              Chancery or such other court shall deem proper.

         (c)  To the extent that a present or former director, officer,
              employee or agent of a corporation has been successful on the
              merits or otherwise in defense of any action, suit or proceeding
              referred to in subsections (a) and (b), or in defense of any
              claim, issue or matter therein, such person shall be indemnified
              against expenses (including attorneys' fees) actually and
              reasonably incurred by such person in connection therewith.

         (d)  Any indemnification under subsections (a) and (b) of this Section
              (unless ordered by a court) shall be made by the Corporation only
              as authorized in the specific case upon a determination that
              indemnification of the present or former director, officer,
              employee or agent is proper in the circumstances because such
              person has met the applicable standard of conduct as set forth in
              subsections (a) and (b) of this Section. Such determination shall
              be made (1) by a majority vote of the directors who are not
              parties to such action, suit or proceeding, even though less than
              a quorum, or (2) by a committee of such directors designated by
              majority vote of such directors, even though less than a quorum,
              or (3) if there are no such directors, or if such directors so
              direct, by independent legal counsel in a written opinion, or (4)
              by the stockholders.

         (e)  Expenses (including attorneys' fees) incurred by a present or
              former officer or director in defending any civil, criminal,
              administrative or investigative action, suit or proceeding shall
              be paid by the Corporation in advance of the final disposition of
              such action, suit or proceeding upon receipt of an undertaking by
              or on behalf of the director or officer to repay such amount if
              it shall ultimately be determined that such person is not
              entitled to be indemnified by the Corporation as authorized in
              this Section. Once the Corporation has received the undertaking,
              the Corporation shall pay the officer or director within 30 days
              of receipt by the Corporation of a written application from the
              officer or director for the expenses incurred by that officer or
              director. In the event the Corporation fails to pay within the
              30-day period, the applicant shall have the right to sue for
              recovery of the expenses contained in the written application
              and, in addition, shall recover all attorneys' fees and expenses
              incurred in the action to enforce the application and the rights
              granted in this Section 7.07. Expenses (including attorneys'
              fees) incurred by other employees and agents shall be paid upon
              such terms and conditions, if any, as the Board of Directors
              deems appropriate.

         (f)  The indemnification and advancement of expenses provided by, or
              granted pursuant to, the other subsections of this Section shall
              not be deemed exclusive of any other rights to which those
              seeking indemnity or advancement of expenses may be entitled
              under any bylaw, agreement, vote of stockholders or disinterested
              directors or otherwise, both as to action in such person's
              official capacity and as to action in another capacity while
              holding such office.

         (g)  The Corporation may purchase and maintain insurance on behalf of
              any person who is or was a director, officer, employee or agent
              of the Corporation, or is or was serving at the request of the
              Corporation as a director, officer, employee or agent of another
              corporation, partnership, joint venture, trust or other
              enterprise, against any liability asserted against such person
              and incurred by such person in any such capacity, or arising out
              of such person's status as such, whether or not the Corporation
              would have the power to indemnify such person against such
              liability under the provisions of this Section.

         (h)  For the purposes of this Section, references to "the Corporation"
              include all constituent corporations absorbed in a consolidation
              or merger, as well as the resulting or surviving corporation, so
              that any person who is or was a director, officer, employee or
              agent of such a constituent corporation or is or was serving at
              the request of such constituent corporation as a director,
              officer, employee or agent of another corporation, partnership,
              joint venture, trust or other enterprise, shall stand in the same
              position under the provisions of this Section with respect to the
              resulting or surviving corporation as such person would if such
              person had served the resulting or surviving corporation in the
              same capacity.



                                      II-2



         (i)  For purposes of this Section, references to "other enterprises"
              shall include employee benefit plans; references to "fines" shall
              include any excise taxes assessed on a person with respect to any
              employee benefit plan; and references to "serving at the request
              of the Corporation" shall include any service as a director,
              officer, employee or agent of the Corporation which imposes
              duties on, or involves services by, such director, officer,
              employee or agent with respect to an employee benefit plan, its
              participants or beneficiaries; and a person who acted in good
              faith and in a manner such person reasonably believed to be in
              the interest of the participants and beneficiaries of an employee
              benefit plan shall be deemed to have acted in a manner "not
              opposed to the best interests of the Corporation" as referred to
              in this Section.

         (j)  The indemnification and advancement of expenses provided by, or
              granted pursuant to, this Section shall, unless otherwise
              provided when authorized or ratified, continue as to a person who
              has ceased to be a director, officer, employee or agent and shall
              inure to the benefit of the heirs, executors and administrators
              of such a person.

         Section 145 of the General Corporation Law of the state of Delaware
provides for indemnification of our directors and officers in a variety of
circumstances, which may include liabilities under the Securities Act of 1933.
We maintain liability insurance protecting us, as well as our directors and
officers, against liability by reason of their being or having been our
directors or officers.

ITEM 17.  UNDERTAKINGS.

         (a)   The undersigned registrant hereby undertakes:

               (1)  To file, during any period in which offers or sales are
                    being made, a post-effective amendment to this registration
                    statement:

                    (i)  To include any prospectus required by Section 10(a)(3)
                         of the Securities Act of 1933;

                    (ii) To reflect in the prospectus any facts or events
                         arising after the effective date of the registration
                         statement (or the most recent post-effective amendment
                         thereof) which, individually or in the aggregate,
                         represent a fundamental change in the information set
                         forth in the registration statement. Notwithstanding
                         the foregoing, any increase or decrease in volume of
                         securities offered (if the total dollar value of
                         securities offered would not exceed that which was
                         registered) and any deviation from the low or high end
                         of the estimated maximum offering range may be
                         reflected in the form of prospectus filed with the SEC
                         pursuant to Rule 424(b) if, in the aggregate, the
                         changes in volume and price represent no more than 20
                         percent change in the maximum aggregate offering price

                         set forth in the "Calculation of Registration Fee"
                         table in the effective registration statement; and

                    (iii) To include any material information with respect to
                         the plan of distribution not previously disclosed in
                         the registration statement or any material change to
                         such information in the registration statement;

                    provided, however, that paragraphs (a)(1)(i) and
                    (a)(1)(ii) do not apply if the information required
                    to be included in a post-effective amendment by those
                    paragraphs is contained in periodic reports filed
                    with or furnished to the SEC by the registrant
                    pursuant to Section 13 or Section 15(d) of the
                    Securities Exchange Act of 1934 that are incorporated
                    by reference in the registration statement.

               (2)  That, for the purpose of determining any liability under the
                    Securities Act of 1933, each such post-effective amendment
                    shall be deemed to be a new registration statement relating
                    to the securities offered therein, and the offering of such
                    securities at that time shall be deemed to be the initial
                    bona fide offering thereof.

               (3)  To remove from registration by means of a post-effective
                    amendment any of the securities being registered which
                    remain unsold at the termination of the offering.

               (4)  That, for purposes of determining any liability under the
                    Securities Act of 1933, each filing of the registrant's
                    Annual Report pursuant to Section 13(a) or Section 15(d) of
                    the Securities Exchange Act of 1934 that is incorporated by
                    reference in the registration statement shall be deemed to
                    be a new registration statement relating to the securities
                    offered herein, and the offering of such securities at that
                    time shall be deemed to be the initial bona fide offering
                    thereof.

          (b)  Insofar as indemnification for liabilities arising under the
               Securities Act of 1933 may be permitted to directors, officers
               and controlling persons of the registrant pursuant to the
               provisions described under Item 15 above, or otherwise, the
               registrant has been advised that in the opinion of the SEC such
               indemnification is against public policy as expressed in the
               Securities Act of 1933 and is, therefore, unenforceable. In the
               event that a claim for indemnification against such liabilities
               (other than the payment by the registrant of expenses incurred or
               paid by a director, officer or controlling person of the
               registrant in the successful defense of any action, suit or
               proceeding) is asserted by such director, officer or controlling
               person in connection with the securities being registered, the
               registrant will, unless in the opinion of its counsel the matter
               has been settled by controlling precedent, submit to a court of
               appropriate jurisdiction the question whether such
               indemnification by it is against public policy as expressed in
               the Securities Act of 1933, and will be governed by the final
               adjudication of such issue.

          (c)  The undersigned registrant hereby undertakes that:

               (1)  For purposes of determining any liability under the
                    Securities Act of 1933, the information omitted from the
                    form of prospectus filed as part of this registration
                    statement in reliance upon Rule 430A and contained in a form
                    of prospectus filed by the registrant pursuant to Rule
                    424(b) (1) or (4) or 497(h) under the Securities Act shall
                    be deemed to be part of this registration statement as of
                    the time it was declared effective.

               (2)  For the purpose of determining any liability under the
                    Securities Act of 1933, each post-effective amendment that
                    contains a form of prospectus shall be deemed to be a new
                    registration statement relating to the securities offered
                    therein, and the offering of such securities at that time
                    shall be deemed to be the initial bona fide offering
                    thereof.
