                      MDU RESOURCES GROUP, INC.
                        NOTES TO CONSOLIDATED
                        FINANCIAL STATEMENTS

                       June 30, 2003 and 2002
                             (Unaudited)

 1.  Basis of presentation

          The accompanying consolidated interim financial statements
     were prepared in conformity with the basis of presentation
     reflected in the consolidated financial statements included in
     the Annual Report to Stockholders for the year ended
     December 31, 2002 (2002 Annual Report), and the standards of
     accounting measurement set forth in Accounting Principles Board
     (APB) Opinion No. 28 and any amendments thereto adopted by the
     Financial Accounting Standards Board (FASB).  Interim financial
     statements do not include all disclosures provided in annual
     financial statements and, accordingly, these financial
     statements should be read in conjunction with those appearing
     in the Company's 2002 Annual Report.  The information is
     unaudited but includes all adjustments which are, in the
     opinion of management, necessary for a fair presentation of the
     accompanying consolidated interim financial statements.

2.   Seasonality of operations

          Some of the Company's operations are highly seasonal and
     revenues from, and certain expenses for, such operations may
     fluctuate significantly among quarterly periods.  Accordingly,
     the interim results for particular segments, and for the
     Company as a whole, may not be indicative of results for the
     full fiscal year.

3.   Allowance for doubtful accounts

          The Company's allowance for doubtful accounts as of
     June 30, 2003 and 2002, and December 31, 2002, was $8.3
     million, $8.4 million and $8.2 million, respectively.

 4.  Earnings per common share

          Basic earnings per common share were computed by dividing
     earnings on common stock by the weighted average number of
     shares of common stock outstanding during the year.  Diluted
     earnings per common share were computed by dividing earnings on
     common stock by the total of the weighted average number of
     shares of common stock outstanding during the year, plus the
     effect of outstanding stock options, restricted stock grants
     and performance share awards.  For the three months and six
     months ended June 30, 2003, 139,870 shares and 2,333,480
     shares, respectively, with an average exercise price of $36.85
     and $30.16, respectively, attributable to outstanding stock
     options, were excluded from the calculation of diluted earnings
     per share because their effect was antidilutive.  For the three
     months and six months ended June 30, 2002, 150,630 shares and
     2,567,050 shares, respectively, with an average exercise price
     of $36.86 and $30.15, respectively, attributable to outstanding
     stock options were excluded from the calculation of diluted
     earnings per share because their effect was antidilutive.
     Common stock outstanding includes issued shares less shares
     held in treasury.

 5.  Stock-based compensation

          The Company has stock option plans for directors, key
     employees and employees and accounts for these option plans in
     accordance with APB Opinion No. 25 under which no compensation
     cost has been recognized.

          The following table illustrates the effect on earnings and
     earnings per common share as if the Company had applied
     Statement of Financial Accounting Standards (SFAS) No. 123,
     "Accounting for Stock-Based Compensation" to its stock-based
     compensation:

     Income taxes                              $ 31,263   $ 40,589

 7.  Reclassifications

          Certain reclassifications have been made in the financial
     statements for the prior period to conform to the current
     presentation.  Such reclassifications had no effect on net
     income or stockholders' equity as previously reported.

 8.  New accounting standards

          In June 2001, the FASB approved SFAS No. 141, "Business
     Combinations," which requires the purchase method of accounting
     for business combinations initiated after June 30, 2001 and
     eliminates the pooling-of-interests method.  In June 2001, the
     FASB also approved SFAS No. 142, "Goodwill and Other Intangible
     Assets," which discontinues the practice of amortizing goodwill
     and indefinite lived intangible assets and initiates an annual
     review for impairment.  Intangible assets with a determinable
     useful life will continue to be amortized over that period.
     The amortization provisions apply to goodwill and intangible
     assets acquired after June 30, 2001.  SFAS No. 141 and SFAS No.
     142 clarify that more assets should be distinguished and
     classified between tangible and intangible.  The Company did
     not change or reclassify contractual mineral rights included in
     property, plant and equipment related to its natural gas and
     oil production business upon adoption of SFAS No. 142.  The
     Company has included such mineral rights as part of property,
     plant and equipment under the full cost method of accounting
     for natural gas and oil properties.  The SEC has recently
     questioned under SFAS No. 142 whether contractual mineral
     rights should be classified as intangible rather than as part
     of property, plant and equipment and has referred this
     accounting matter to the Emerging Issues Task Force and is
     continuing its dialog with the FASB Staff.  The resolution of
     this matter may result in certain reclassifications to the
     Company's Consolidated Balance Sheets, as well as changes to
     the Company's Notes to Consolidated Financial Statements in the
     future.  The applicable provisions of SFAS No. 141 and SFAS
     No. 142 only impact balance sheet and associated footnote
     disclosure, so any reclassifications that might be required
     in the future will not impact the Company's cash flows or
     results of operations.  The Company believes that the
     resolution of this matter will not have a material effect on
     the Company's financial position because the mineral rights
     acquired by its natural gas and oil production business after
     the June 30, 2001, effective date are not material.

          In June 2001, the FASB approved 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 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.  SFAS No. 143 is effective for fiscal years
     beginning after June 15, 2002.  For more information on the
     adoption of SFAS No. 143, see Note 13.

          In April 2002, the FASB approved SFAS No. 145, "Rescission
     of FASB Statements No. 4, 44 and 64, Amendment of FASB
     Statement No. 13, and Technical Corrections."  FASB No. 4
     required all gains or losses from extinguishment of debt to be
     classified as extraordinary items net of income taxes.  SFAS
     No. 145 requires that gains and losses from extinguishment of
     debt be evaluated under the provisions of APB Opinion No. 30,
     and be classified as ordinary items unless they are unusual or
     infrequent or meet the specific criteria for treatment as an
     extraordinary item.  SFAS No. 145 is effective for fiscal years
     beginning after May 15, 2002.  The adoption of SFAS No. 145 did
     not have a material effect on the Company's financial position
     or results of operations.

          In November 2002, the FASB issued FASB Interpretation
     No. 45, "Guarantor's Accounting and Disclosure Requirements for
     Guarantees, Including Indirect Guarantees of Indebtedness of
     Others" (FIN 45).  FIN 45 clarifies the disclosures to be made
     by a guarantor in its interim and annual financial statements
     about its obligations under certain guarantees that it has
     issued.  FIN 45 also requires a guarantor to recognize, at the
     inception of a guarantee, a liability for the fair value of the
     obligation undertaken in issuing certain types of guarantees.
     Certain types of guarantees are not subject to the initial
     recognition and measurement provisions of FIN 45 but are
     subject to its disclosure requirements.  The initial
     recognition and initial measurement provisions of FIN 45 are
     applicable on a prospective basis to guarantees issued or
     modified after December 31, 2002, regardless of the guarantor's
     fiscal year-end.  The guarantor's previous accounting for
     guarantees issued prior to the date of the initial application
     of FIN 45 shall not be revised or restated.  The disclosure
     requirements in FIN 45 are effective for financial statements
     of interim or annual periods ended after December 15, 2002.
     The Company will apply the initial recognition and initial
     measurement provisions of FIN 45 to guarantees issued or
     modified after December 31, 2002.  For more information on the
     Company's guarantees and the disclosure requirements of FIN 45,
     as applicable to the Company, see Note 18.

          In January 2003, the FASB issued FASB Interpretation
     No. 46, "Consolidation of Variable Interest Entities" (FIN 46).
     FIN 46 clarifies the application of Accounting Research
     Bulletin No. 51, "Consolidated Financial Statements" to certain
     entities in which equity investors do not have the
     characteristics of a controlling financial interest or do not
     have sufficient equity at risk for the entity to finance its
     activities without additional subordinated support from other
     parties.  FIN 46 requires existing unconsolidated variable
     interest entities to be consolidated by their primary
     beneficiaries if the entities do not effectively disperse risks
     among parties involved.  All companies with variable interests
     in variable interest entities created after January 31, 2003,
     shall apply the provisions of FIN 46 to those entities
     immediately.  FIN 46 is effective for the first fiscal year or
     interim period beginning after June 15, 2003, for variable
     interest entities created before February 1, 2003.  The Company
     will prospectively apply the provisions of FIN 46 that were
     effective January 31, 2003.

          The Company evaluated the provisions of FIN 46 for
     entities created before February 1, 2003. Based on this
     evaluation, the Company determined that MPX Holdings, Ltda.
     (MPX) is a variable interest entity.  MPX was formed in August
     2001, as a result of MDU Brasil Ltda. (MDU Brasil), an indirect
     wholly owned Brazilian subsidiary of the Company, entering into
     a joint venture agreement with a Brazilian firm.  MDU Brasil
     has a 49 percent interest in MPX.  Although the Company has
     determined that MPX is a variable interest entity, MDU Brasil
     is not considered the primary beneficiary of MPX because MDU
     Brasil does not absorb a majority of MPX's expected losses or
     receive a majority of MPX's expected residual returns.
     Therefore, MDU Brasil does not have a controlling financial
     interest in MPX and is not required to consolidate MPX in its
     financial statements.  MPX is being accounted for under the
     equity method of accounting.  For more information on the
     equity method investment, see Note 10.  The adoption of FIN 46
     did not have a material effect on the Company's financial
     position or results of operations.

          In April 2003, the FASB issued SFAS No. 149, "Amendment of
     Statement 133 on Derivative Instruments and Hedging
     Activities."  SFAS No. 149 provides clarification on the
     financial accounting and reporting of derivative instruments,
     including certain derivative instruments embedded in other
     contracts, and hedging activities; and requires contracts with
     similar characteristics to be accounted for on a comparable
     basis.  SFAS No. 149 is generally effective for contracts
     entered into or modified after June 30, 2003, and for hedging
     relationships designated after June 30, 2003.  The Company does
     not expect SFAS No. 149 to have a material effect on its
     financial position or results of operations.

          In May 2003, the FASB issued SFAS No. 150, "Accounting for
     Certain Financial Instruments with Characteristics of Both
     Liabilities and Equity."  SFAS No. 150 establishes standards
     for how an issuer classifies and measures certain financial
     instruments with characteristics of both liabilities and
     equity.  It requires that an issuer classify a financial
     instrument that is within the scope of SFAS No. 150 as a
     liability (or an asset in some circumstances).  SFAS No. 150 is
     effective for financial instruments entered into or modified
     after May 31, 2003, and otherwise is effective at the beginning
     of the first interim period beginning after June 15, 2003.  The
     Company will apply SFAS No. 150 to any financial instruments
     entered into or modified after May 31, 2003.  The Company is
     currently evaluating the effect of SFAS No. 150 for financial
     instruments entered into on or before May 31, 2003, on its
     financial position and results of operations.

 9.  Comprehensive income

          Comprehensive income is the sum of net income as reported
     and other comprehensive income (loss).  The Company's other
     comprehensive loss resulted from gains (losses) on derivative
     instruments qualifying as hedges, a minimum pension liability
     adjustment and foreign currency translation adjustments.

          The Company's comprehensive income, and the components of
     other comprehensive loss, and their related tax effects, were
     as follows:

10.  Equity method investment

          In August 2001, MDU Brasil entered into a joint venture
     agreement with a Brazilian firm under which the parties formed
     MPX.  MDU Brasil has a 49 percent interest in MPX which is a
     variable interest entity, as discussed in Note 8.  However, MDU
     Brasil does not have a controlling financial interest in MPX
     and is not required to consolidate MPX in its financial
     statements.  Therefore, MPX is being accounted for under the
     equity method of accounting.  MPX, through a wholly owned
     subsidiary, owns a 220-megawatt natural gas-fired power plant
     (Project) in the Brazilian state of Ceara.  MPX has assets at
     June 30, 2003, of approximately $95 million.  Petrobras, the
     Brazilian state-controlled energy company, has agreed to
     purchase all of the capacity and market all of the Project's
     energy.  The power purchase agreement with Petrobras expires in
     May 2008 and is renewable for an additional 13 years.  The
     functional currency for the Project is the Brazilian real.  The
     power purchase agreement with Petrobras contains an embedded
     derivative, which derives its value from an annual adjustment
     factor, which largely indexes the contract capacity payments to
     the U.S. dollar.  For the three and six months ended June 30,
     2003, the Company's 49 percent share of the loss from the
     embedded derivative in the power purchase agreement was $4.5
     million (after tax) and $6.0 million (after tax), respectively.
     In addition, the Company's 49 percent share of the foreign
     currency gains resulting from revaluation of the Brazilian real
     totaled $2.2 million (after tax) and $3.1 million (after tax)
     for the three months and six months ended June 30, 2003,
     respectively.

          The Company's investment in the Project has been
     accounted for under the equity method of accounting, and the
     Company's share of net income, including the previously
     mentioned foreign currency gain and loss from the embedded
     derivative in the power purchase agreement, for the three
     months and six months ended June 30, 2003, of $1.3 million and
     $1.8 million, respectively, was included in other income - net.
     At June 30, 2003 and 2002, and December 31, 2002, the Company's
     investment in the Project was approximately $20.6 million,
     $23.8 million and $27.8 million, respectively.

          The unamortizable intangible assets were recognized in
     accordance with SFAS No. 87, "Employers' Accounting for
     Pensions" which requires that if an additional minimum
     liability is recognized an equal amount shall be recognized as
     an intangible asset, provided that the asset recognized shall
     not exceed the amount of unrecognized prior service cost.  The
     unamortizable intangible asset will be eliminated or adjusted
     as necessary upon a new determination of the amount of
     additional liability.

          Amortization expense for amortizable intangible assets for
     the three months and six months ended June 30, 2003, was $1.6
     million and $2.8 million, respectively.  Amortization expense
     for amortizable intangible assets for the three months and six
     months ended June 30, 2002, and for the year ended December 31,
     2002, was $472,000, $703,000 and $3.4 million, respectively.
     Estimated amortization expense for amortizable intangible
     assets is $6.0 million in 2003, $6.1 million in 2004, $6.2
     million in 2005, $5.1 million in 2006, $5.0 million in 2007 and
     $160.7 million thereafter.

          For more information on goodwill and other intangible
     assets, see Note 8.

12.  Derivative instruments

          From time to time, the Company utilizes derivative
     instruments as part of an overall energy price, foreign
     currency and interest rate risk management program to
     efficiently manage and minimize commodity price, foreign
     currency and interest rate risk.  The following information
     should be read in conjunction with Notes 1 and 5 in the
     Company's Notes to Consolidated Financial Statements in the
     2002 Annual Report.

          As of June 30, 2003, a subsidiary of the Company held
     derivative instruments designated as cash flow hedging
     instruments.

     Hedging activities

          A subsidiary of the Company utilizes natural gas and oil
     price swap and collar agreements to manage a portion of the
     market risk associated with fluctuations in the price of
     natural gas and oil on the subsidiary's forecasted sales of
     natural gas and oil production.

          For the three months and six months ended June 30, 2003
     and 2002, the amount of hedge ineffectiveness recognized, which
     was included in operating revenues, was immaterial.  For the
     three months and six months ended June 30, 2003 and 2002, the
     subsidiary did not exclude any components of the derivative
     instruments' gain or loss from the assessment of hedge
     effectiveness and there were no reclassifications into earnings
     as a result of the discontinuance of hedges.

          Gains and losses on derivative instruments that are
     reclassified from accumulated other comprehensive income (loss)
     to current-period earnings are included in the line item in
     which the hedged item is recorded.  As of June 30, 2003, the
     maximum term of the subsidiary's swap and collar agreements, in
     which the subsidiary of the Company is hedging its exposure to
     the variability in future cash flows for forecasted
     transactions, is 18 months.  The subsidiary of the Company
     estimates that over the next twelve months net losses of
     approximately $9.2 million (after tax) will be reclassified
     from accumulated other comprehensive loss into earnings,
     subject to changes in natural gas and oil market prices, as the
     hedged transactions affect earnings.

13.  Asset retirement obligations

          The Company adopted SFAS No. 143 on January 1, 2003.  The
     Company 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.

          Upon adoption of SFAS No. 143, the Company 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).  The Company believes 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.  The Company will continue to defer those SFAS No.
     143 expenses that it believes will be recovered in rates over
     time.  In addition to the $22.5 million liability recorded upon
     the adoption of SFAS No. 143, the Company had previously
     recorded a $7.5 million liability related to retirement
     obligations.

          A reconciliation of the Company's liability was as
     follows:

     January 1, 2003                               $  29,997
     Liabilities incurred                                548
     Liabilities acquired                                626

          This liability is included in other liabilities.  If SFAS
     No. 143 had been in effect during 2002, the Company's liability
     would have been approximately $27.0 million and $28.1 million
     at January 1, 2002, and June 30, 2002, respectively.

          The fair value of assets that are legally restricted for
     purposes of settling asset retirement obligations at June 30,
     2003, was $5.3 million.

14.  Long-term debt

          Centennial borrowed an additional $39 million in the first
     quarter of 2003 under its long-term master shelf agreement.
     Under the terms of the master shelf agreement, $394.6 million
     was outstanding at June 30, 2003.  In addition, Centennial
     entered into a $125 million note purchase agreement on June 27,
     2003.  The $125 million in proceeds was used to pay down
     Centennial commercial paper program borrowings.  Borrowings
     outstanding that were classified as long-term debt under the
     Company's and Centennial's commercial paper programs totaled
     $108.1 million at June 30, 2003, compared to $151.9 million at
     December 31, 2002.

15.  Business segment data

          The Company's reportable segments are those that are based
     on the Company's method of internal reporting, which generally
     segregates the strategic business units due to differences in
     products, services and regulation.  The Company has six
     reportable segments consisting of electric, natural gas
     distribution, utility services, pipeline and energy services,
     natural gas and oil production and construction materials and
     mining.  During the fourth quarter of 2002, the Company
     separated independent power production and other operations
     from its reportable segments.  The independent power
     production and other operations do not individually meet the
     criteria to be considered a reportable segment.  All prior
     period information has been restated to reflect this change.

          The vast majority of the Company's operations are located
     within the United States.  The Company also has investments in
     foreign countries, which consist largely of an investment in a
     natural gas-fired electric generation station in Brazil as
     discussed in Note 10.  The electric segment generates,
     transmits and distributes electricity and the natural gas
     distribution segment distributes natural gas.  These operations
     also supply related value-added products and services in the
     northern Great Plains.  The utility services segment consists
     of a diversified infrastructure company specializing in
     electric, gas and telecommunication utility construction, as
     well as industrial and commercial electrical, exterior lighting
     and traffic signalization throughout most of the United States.
     Utility services also provides related specialty equipment
     manufacturing, sales and rental services.  The pipeline and
     energy services segment provides natural gas transportation,
     underground storage and gathering services through regulated
     and nonregulated pipeline systems primarily in the Rocky
     Mountain and northern Great Plains regions of the United
     States.  The pipeline and energy services segment also provides
     energy-related management services, including cable and
     pipeline magnetization and locating.  The natural gas and oil
     production segment is engaged in natural gas and oil
     acquisition, exploration and production activities primarily in
     the Rocky Mountain region of the United States and in the Gulf
     of Mexico.  The construction materials and mining segment mines
     aggregates and markets crushed stone, sand, gravel and related
     construction materials, including ready-mixed concrete, cement,
     asphalt and other value-added products, as well as performs
     integrated construction services, in the north central and
     western United States and in the states of Alaska, Hawaii and
     Texas.  The independent power production and other operations
     include electric generating facilities in the United States and
     Brazil and investments in potential new growth opportunities
     that are not directly being pursued by the Company's other
     businesses.

16.  Acquisitions

          During the first six months of 2003, the Company acquired
     a number of businesses, none of which was individually
     material, including construction materials and mining
     businesses in Montana and North Dakota and a wind-powered
     electric generation facility in California.  The total purchase
     consideration for these businesses and adjustments with respect
     to certain other acquisitions acquired in 2002, including the
     Company's common stock and cash, was $120.1 million.

          The above 2003 acquisitions were accounted for under the
     purchase method of accounting and accordingly, the acquired
     assets and liabilities assumed have been preliminarily recorded
     at their respective fair values as of the date of acquisition.
     Final fair market values are pending the completion of the
     review of the relevant assets, liabilities and issues identified
     as of the acquisition date.  The results of operations of the
     acquired businesses are included in the financial statements
     since the date of each acquisition.  Pro forma financial amounts
     reflecting the effects of the above acquisitions are not
     presented as such acquisitions were not material to the
     Company's financial position, results of operations or cash
     flows.

17.  Regulatory matters and revenues subject to refund

          On May 30, 2003, Montana-Dakota filed an application with
     the North Dakota Public Service Commission (NDPSC) for an
     electric rate increase.  Montana-Dakota requested a total of
     $7.8 million annually or 9.1 percent above current rates.  The
     application included an interim request of $2.4 million
     effective July 1, 2003, related to the recovery of costs for
     additional investments and costs incurred for new generation
     resources.  The NDPSC has not acted on the interim request.  A
     final order from the NDPSC is due January 30, 2004.

          In December 2002, Montana-Dakota filed an application with
     the South Dakota Public Utilities Commission (SDPUC) for a
     natural gas rate increase.  Montana-Dakota requested a total of
     $2.2 million annually or 5.8 percent above current rates.  A
     final order from the SDPUC was due June 30, 2003.  However, on
     June 13, 2003, Montana-Dakota and the SDPUC Staff filed a
     motion to continue and reschedule the hearing and further
     suspend rates.  On July 1, 2003, the SDPUC granted the motion
     to continue and reschedule the hearing and further suspend
     rates.  A final order from the SDPUC is expected in late 2003.

          In October 2002, Great Plains filed an application with
     the Minnesota Public Utilities Commission (MPUC) for a natural
     gas rate increase.  Great Plains requested a total of $1.6
     million annually or 6.9 percent above current rates.  In
     December 2002, the MPUC issued an Order setting interim rates
     that approved an interim increase of $1.4 million annually
     effective December 6, 2002.  Great Plains began collecting such
     rates effective December 6, 2002, subject to refund until the
     MPUC issues a final order.  On May 13, 2003, Great Plains and
     the Minnesota Department of Commerce (DOC), the only intervener
     in the proceeding, filed a Stipulation with the MPUC agreeing
     to an increase of $1.1 million annually.  A hearing before the
     MPUC on the Stipulation was held on June 13, 2003, at which
     time the MPUC took under advisement the Stipulation agreed upon
     by Great Plains and the DOC.  The due date for a final order
     from the MPUC was extended and is now due October 22, 2003.

          Reserves have been provided for a portion of the revenues
     that have been collected subject to refund for certain of the
     above proceedings.  The Company believes that such reserves are
     adequate based on its assessment of the ultimate outcome of the
     proceedings.

          In December 1999, Williston Basin Interstate Pipeline
     Company (Williston Basin), an indirect wholly owned subsidiary
     of the Company, filed a general natural gas rate change
     application with the Federal Energy Regulatory Commission
     (FERC).  Williston Basin began collecting such rates effective
     June 1, 2000, subject to refund.  In May 2001, the
     Administrative Law Judge (ALJ) issued an Initial Decision on
     Williston Basin's natural gas rate change application.  The
     Initial Decision addressed numerous issues relating to the rate
     change application, including matters relating to allowable
     levels of rate base, return on common equity, and cost of
     service, as well as volumes established for purposes of cost
     recovery, and cost allocation and rate design.  On July 3,
     2003, the FERC issued its Order on Initial Decision.  The Order
     affirms the ALJ's Initial Decision on many of the issues
     including rate base and certain cost of service items as well
     as volumes to be used for purposes of cost recovery, and cost
     allocation and rate design.  However, there are other issues as
     to which FERC differs with the ALJ including return on common
     equity and the correct level of corporate overhead expense.  On
     August 4, 2003, Williston Basin requested rehearing of a number
     of issues including determinations associated with cost of
     service, throughput, and cost allocation and rate design, as
     discussed in the FERC's Order.  Williston Basin is unable to
     predict the timing of a decision by the FERC on the issues
     raised in the rehearing request.

          Reserves have been provided for a portion of the revenues
     that have been collected subject to refund with respect to
     Williston Basin's pending regulatory proceeding.  Williston
     Basin believes that such reserves are adequate based on its
     assessment of the ultimate outcome of the proceeding.

18.  Contingencies

     Litigation

          In January 2002, Fidelity Oil Co. (FOC), one of the
     Company's natural gas and oil production subsidiaries, entered
     into a compromise agreement with the former operator of certain
     of FOC's oil production properties in southeastern Montana.
     The compromise agreement resolved litigation involving the
     interpretation and application of contractual provisions
     regarding net proceeds interests paid by the former operator to
     FOC for a number of years prior to 1998.  The terms of the
     compromise agreement are confidential.  As a result of the
     compromise agreement, the natural gas and oil production
     segment reflected a gain in its financial results for the first
     quarter of 2002 of approximately $16.6 million after tax.  As
     part of the settlement, FOC gave the former operator a full and
     complete release, and FOC is not asserting any such claim
     against the former operator for periods after 1997.

          In July 1996, Jack J. Grynberg (Grynberg) filed suit in
     United States District Court for the District of Columbia (U.S.
     District Court) against Williston Basin and over 70 other
     natural gas pipeline companies.  Grynberg, acting on behalf of
     the United States under the Federal False Claims Act, alleged
     improper measurement of the heating content and volume of
     natural gas purchased by the defendants resulting in the
     underpayment of royalties to the United States.  In March 1997,
     the U.S. District Court dismissed the suit without prejudice
     and the dismissal was affirmed by the United States Court of
     Appeals for the D.C. Circuit in October 1998.  In June 1997,
     Grynberg filed a similar Federal False Claims Act suit against
     Williston Basin and Montana-Dakota and filed over 70 other
     separate similar suits against natural gas transmission
     companies and producers, gatherers, and processors of natural
     gas.  In April 1999, the United States Department of Justice
     decided not to intervene in these cases.  In response to a
     motion filed by Grynberg, the Judicial Panel on Multidistrict
     Litigation consolidated all of these cases in the Federal
     District Court of Wyoming (Federal District Court).  Oral
     argument on motions to dismiss was held before the Federal
     District Court in March 2000.  In May 2001, the Federal
     District Court denied Williston Basin's and Montana-Dakota's
     motion to dismiss.  The matter is currently in the discovery
     stage.  Grynberg has not specified the amount he seeks to
     recover.  Williston Basin and Montana-Dakota are unable to
     estimate their potential exposure and will be unable to do so
     until discovery is completed.  Williston Basin and Montana-
     Dakota believe that the Grynberg case will ultimately be
     dismissed because Grynberg is not, as is required by the
     Federal False Claims Act, the original source of the
     information underlying the action.  Failing this, Williston
     Basin and Montana-Dakota believe Grynberg will not recover
     damages from Williston Basin and Montana-Dakota because
     insufficient facts exist to support the allegations.  Williston
     Basin and Montana-Dakota intend to vigorously contest this
     suit.

          The Quinque Operating Company (Quinque), on behalf of
     itself and subclasses of gas producers, royalty owners and
     state taxing authorities, instituted a legal proceeding in
     State District Court for Stevens County, Kansas, (State
     District Court) against over 200 natural gas transmission
     companies and producers, gatherers, and processors of natural
     gas, including Williston Basin and Montana-Dakota.  The
     complaint, which was served on Williston Basin and Montana-
     Dakota in September 1999, contains allegations of improper
     measurement of the heating content and volume of all natural
     gas measured by the defendants other than natural gas produced
     from federal lands.  The plaintiffs have not specified the
     amount they seek to recover.  In September 2002, the plaintiffs
     moved for certification of the case as a class action and on
     April 10, 2003, the State District Court denied the motion.  On
     May 12, 2003, the plaintiffs filed a motion to file an amended
     class action petition.  Neither Williston Basin nor Montana-
     Dakota were named as defendants in the amended class action
     petition.  The motion to amend the class petition was granted
     by the State District Court on July 28, 2003, and as a result
     Williston Basin and Montana-Dakota are no longer defendants in
     this proceeding.

          The Company is also involved in other legal actions in the
     ordinary course of its business.  Although the outcomes of any
     such legal actions cannot be predicted, management believes
     that the outcomes with respect to these other legal proceedings
     will not have a material adverse effect upon the Company's
     financial position or results of operations.

     Environmental matters

          In December 2000, Morse Bros., Inc. (MBI), an indirect
     wholly owned subsidiary of the Company, was named by the United
     States Environmental Protection Agency (EPA) as a Potentially
     Responsible Party in connection with the cleanup of a
     commercial property site, acquired by MBI in 1999, and part of
     the Portland, Oregon, Harbor Superfund Site.  Sixty-eight other
     parties were also named in this administrative action.  The EPA
     wants responsible parties to share in the cleanup of sediment
     contamination in the Willamette River.  To date, costs of the
     overall remedial investigation of the harbor site for both the
     EPA and the Oregon State Department of Environmental Quality
     (DEQ) are being recorded, and initially paid, through an
     administrative consent order by the Lower Willamette Group
     (LWG), a group of ten entities which does not include MBI.  The
     LWG estimates the overall remedial investigation and
     feasibility study will cost approximately $10 million.  It is
     not possible to estimate the cost of a corrective action plan
     until the remedial investigation and feasibility study has been
     completed, the EPA has decided on a strategy, and a record of
     decision has been published.  While the remedial investigation
     and feasibility study for the harbor site has commenced, it is
     expected to take several years to complete.  The development of
     a proposed plan and record of decision on the harbor site is
     not anticipated to occur until 2006, after which a cleanup plan
     will be undertaken.

          Based upon a review of the Portland Harbor sediment
     contamination evaluation by the DEQ and other information
     available, MBI does not believe it is a Responsible Party.  In
     addition, MBI has notified Georgia-Pacific West, Inc., the
     seller of the commercial property site to MBI, that it intends
     to seek indemnity for any and all liabilities incurred in
     relation to the above matters, pursuant to the terms of their
     sale agreement.

          The Company believes it is not probable that it will incur
     any material environmental remediation costs or damages in
     relation to the above administrative action.

     Guarantees

          Centennial has unconditionally guaranteed a portion of
     certain bank borrowings of MPX and a foreign currency swap
     agreement of MPX in connection with the Company's equity method
     investment in the natural gas-fired electric generation station
     in Brazil, as discussed in Note 10.  The Company, through MDU
     Brasil, owns 49 percent of MPX.  At June 30, 2003, the amount
     of the obligation of the foreign currency swap agreement, which
     expires in 2003, was $30,000. At June 30, 2003, the aggregate
     amount of borrowings outstanding subject to these guarantees
     was $57.1 million and the scheduled repayment of these
     borrowings was $2.1 million in 2003, $12.3 million in 2004 and
     $42.7 million in 2006.  The individual investor, who through
     EBX Empreendimentos Ltda. (EBX), a Brazilian company, owns 51
     percent of MPX, has also guaranteed a portion of these loans.
     These guarantees are not reflected on the Consolidated Balance
     Sheets.

          On June 17, 2003, MPX entered into a five-year credit
     agreement with the U.S. Export-Import Bank under which MPX
     borrowed $50.6 million.  MPX received the proceeds of this loan
     on July 10, 2003, and used the funds to pay outstanding bank
     borrowings.  Centennial and EBX have jointly and severally
     guaranteed repayment of this loan.  Following this refinancing,
     guarantees with respect to approximately $26.4 million will
     terminate upon MPX meeting certain financial covenants under
     the prior financing agreements.

          Centennial and the individual investor have entered into
     reimbursement agreements under which they have agreed to
     reimburse each other to the extent they may be required to make
     any guarantee payments in excess of their proportionate
     ownership share in MPX.

          In addition, Centennial has unconditionally guaranteed
     borrowings under a $10 million credit agreement by a subsidiary
     of the Company.  The proceeds from these borrowings were used
     in connection with the Company's investment in international
     projects.  The amount outstanding under this agreement at
     June 30, 2003, was $5.5 million, which amount is reflected on
     the Consolidated Balance Sheets.  On June 30, 2003, Centennial
     International extended this agreement through September 30,
     2003.  This agreement was terminated on July 11, 2003.  In the
     event this subsidiary of the Company had defaulted under its
     obligation, Centennial would have been required to make
     payments under its guarantee.

          In addition, WBI Holdings has guaranteed certain of its
     subsidiary's natural gas and oil price swap and collar
     agreement obligations.  The amount of the subsidiary's
     obligations at June 30, 2003, was $6.5 million.  There is no
     fixed maximum amount guaranteed in relation to the natural gas
     and oil price swap and collar agreements; however, the amount
     of hedging activity entered into by the subsidiary is limited
     by corporate policy.  The guarantees of the natural gas and oil
     price swap and collar agreements at June 30, 2003, expire in
     December 2003; however, the subsidiary continues to enter into
     additional hedging activities, and, as a result, WBI Holdings
     from time to time will issue additional guarantees on these
     hedging obligations.  The amounts outstanding under the natural
     gas and oil price swap and collar agreements were reflected on
     the Consolidated Balance Sheets.  In the event the above
     subsidiary defaults under its obligations, WBI Holdings would
     be required to make payments under its guarantees.

          Certain subsidiaries of the Company have outstanding
     guarantees to third parties that guarantee the performance of
     other subsidiaries of the Company that are related to natural
     gas transportation and sales agreements, electric power supply
     agreements and certain other guarantees.  At June 30, 2003, the
     fixed maximum amounts guaranteed under these agreements
     aggregated $38.2 million.  The amounts of scheduled expiration
     of the maximum amounts guaranteed under these agreements
     aggregate $8.6 million in 2003; $7.6 million in 2004; $5.0
     million in 2005; $12.0 million in 2012; $2.0 million, which is
     subject to expiration 30 days after the receipt of written
     notice and $3.0 million, which has no scheduled maturity date.
     In the event of default under these guarantee obligations, the
     subsidiary issuing the guarantee for that particular obligation
     would be required to make payments under its guarantee.  The
     amount outstanding by subsidiaries of the Company under the
     above guarantees was $165,000 and was reflected on the
     Consolidated Balance Sheets at June 30, 2003.

          WBI Holdings and Fidelity Exploration & Production Company
     (Fidelity), an indirect wholly owned subsidiary of the Company,
     have outstanding guarantees to Williston Basin.  These
     guarantees are related to natural gas transportation and
     storage agreements and guarantee the performance of
     Prairielands Energy Marketing, Inc. (Prairielands), an indirect
     wholly owned subsidiary of the Company.  At June 30, 2003, the
     fixed maximum amounts guaranteed under these agreements
     aggregated $22.0 million. Scheduled expiration of the maximum
     amounts guaranteed under these agreements aggregate $2.0
     million in 2005 and $20.0 million in 2009.  In the event of
     Prairielands' default in its payment obligations, the
     subsidiary issuing the guarantee for that particular obligation
     would be required to make payments under its guarantee.  The
     amount outstanding by Prairielands under the above guarantees
     was $622,000, which was not reflected on the Consolidated
     Balance Sheets at June 30, 2003, because these intercompany
     transactions are eliminated in consolidation.

          In addition, Centennial has issued guarantees related to
     the Company's purchase of maintenance items to third parties
     for which no fixed maximum amounts have been specified.  These
     guarantees have no scheduled maturity date.  In the event a
     subsidiary of the Company defaults under its obligation in
     relation to the purchase of certain maintenance items,
     Centennial would be required to make payments under these
     guarantees.  Any amounts outstanding by subsidiaries of the
     Company for maintenance were reflected on the Consolidated
     Balance Sheets at June 30, 2003.

          As of June 30, 2003, Centennial was contingently liable
     for performance of certain of its subsidiaries under
     approximately $302 million of surety bonds.  These bonds are
     principally for construction contracts and reclamation
     obligations of these subsidiaries, entered into in the normal
     course of business.  Centennial indemnifies the respective
     surety bond companies against any exposure under the bonds.  A
     large portion of these contingent commitments expire in 2003,
     however Centennial will likely continue to enter into surety
     bonds for its subsidiaries in the future.  The surety bonds
     were not reflected on the Consolidated Balance Sheets.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
        AND RESULTS OF OPERATIONS

     The Company has six reportable segments consisting of electric,
natural gas distribution, utility services, pipeline and energy
services, natural gas and oil production and construction materials
and mining.  During the fourth quarter of 2002, the Company
separated independent power production and other operations from its
reportable segments.  The independent power production and other
operations do not individually meet the criteria to be considered a
reportable segment.  All prior period information has been restated
to reflect this change.

     The electric and natural gas distribution segments include the
electric and natural gas distribution operations of Montana-Dakota
and the natural gas distribution operations of Great Plains Natural
Gas Co.  The utility services segment includes all the operations of
Utility Services, Inc.  The pipeline and energy services segment
includes WBI Holdings' natural gas transportation, underground
storage, gathering services, and energy related management services.
The natural gas and oil production segment includes the natural gas
and oil acquisition, exploration and production operations of WBI
Holdings.  The construction materials and mining segment includes
the results of Knife River's operations, while independent power
production and other operations include electric generating
facilities in the United States and Brazil and investments in
potential new growth opportunities that are not directly being
pursued by the Company's other businesses.

     Earnings from electric, natural gas distribution and pipeline
and energy services are substantially all from regulated operations.
Earnings from utility services; natural gas and oil production;
construction materials and mining; and independent power production
and other are all from nonregulated operations.

     Reference should be made to Notes to Consolidated Financial
Statements for information pertinent to various commitments and
contingencies.

________________________________


Three Months Ended June 30, 2003 and 2002

     Consolidated earnings for the quarter ended June 30, 2003,
increased $18.6 million from the comparable period a year ago due to
higher earnings at the natural gas and oil production, independent
power production and other, construction materials and mining,
utility services, pipeline and energy services and electric
businesses.  A higher seasonal loss at the natural gas distribution
business slightly offset the earnings increase.


Six Months Ended June 30, 2003 and 2002

     Consolidated earnings for the six months ended June 30, 2003,
increased $15.0 million from the comparable period a year ago due to
higher earnings at the independent power production and other,
construction materials and mining, pipeline and energy services,
electric and utility services businesses.  Decreased earnings at the
natural gas and oil production and natural gas distribution
businesses slightly offset the earnings increase.

Three Months Ended June 30, 2003 and 2002

Electric

     Electric earnings increased slightly as a result of higher
average sales for resale prices of 34 percent, due to stronger sales
for resale markets, and higher retail sales revenues, due in part to
higher retail sales volumes of 6 percent, primarily to commercial
and large industrial customers.  Partially offsetting the earnings
increase were higher operation and maintenance expense, decreased
sales for resale volumes of 38 percent and increased purchased power
costs, all primarily related to planned maintenance outages at two
generating stations.

Natural Gas Distribution

     Normal seasonal losses at the natural gas distribution business
increased as a result of higher operation and maintenance expense,
primarily due to higher employee benefit-related, payroll and
insurance costs, along with decreased retail sales volumes.  Retail
sales volumes were 18 percent lower due to weather that was 31
percent warmer than the second quarter of the prior year.  Partially
offsetting the earnings decline were higher retail sales rates, the
result of rate increases in Minnesota, Montana, North Dakota and
Wyoming.  The pass-through of higher natural gas prices resulted in
the increase in sales revenues and purchased natural gas sold.  For
further information on the retail rate increases, see Note 17 of
Notes to Consolidated Financial Statements in this Form 10-Q and
Note 17 of Notes to Consolidated Financial Statements in the
Company's Quarterly Report on Form 10-Q for the quarter ended March
31, 2003.

Utility Services

     Utility services earnings increased as a result of the absence
in 2003 of a 2002 write-off of receivables of $1.4 million (after
tax) associated with a company in the telecommunications industry
and the absence in 2003 of a 2002 unfavorable settlement of a
billing dispute of $724,000 (after tax) in the Central region.
Higher line construction margins in the Northwest region and lower
selling, general and administrative expenses also added to the
increase in earnings.  Partially offsetting the earnings increase
were lower margins in the Rocky Mountain region, lower line
construction margins in the Southwest and Central regions and lower
inside electrical margins in the Northwest and Central regions,
reflecting the continuing effects of the soft economy and the
downturn in the telecommunications market.

Pipeline and Energy Services

     Earnings at the pipeline and energy services business increased
as a result of higher gathering volumes of 12 percent, mainly from
increased gathering in the Powder River Basin.  Also adding to the
earnings increase were higher transportation revenues, primarily
higher reservation fees resulting from an increase in firm services,
offset in part by lower transportation volumes, largely the result
of lower volumes transported to storage.  Partially offsetting the
earnings increase were higher operation and maintenance costs.  The
increase in energy services revenue and the related increase in
purchased natural gas sold were due largely to an increase in
natural gas prices since the comparable period last year.

Natural Gas and Oil Production

     Natural gas and oil production earnings increased due to higher
realized natural gas prices of 35 percent, higher natural gas
production of 21 percent, largely from operated properties in the
Rocky Mountain area, and higher average realized oil prices of 14
percent.  Partially offsetting the earnings increase were higher
depreciation, depletion and amortization expense due to higher
natural gas production volumes and higher rates, decreased oil
production of 10 percent and higher interest expense, due primarily
to higher average debt balances.

Construction Materials and Mining

     Construction materials and mining earnings increased due to
increased aggregate volumes, higher construction activity, primarily
due to a large harbor-deepening project in southern California, and
higher ready-mixed concrete and cement volumes, all at existing
operations.  Earnings from companies acquired since the comparable
period last year also added to the earnings increase.  Partially
offsetting the increase in earnings were higher depreciation,
depletion and amortization expense, due to higher aggregate volumes
produced and higher property, plant and equipment balances,
increased selling, general and administrative costs, higher asphalt
oil and fuel costs and lower asphalt volumes at existing operations.

Independent Power Production and Other

     Earnings for the independent power production business
increased largely from domestic businesses acquired since the
comparable period last year, partially offset by higher interest
expense, resulting from higher average debt balances relating to
these acquisitions.  The Brazilian operations also contributed to
the earnings increase.  The Company's $1.3 million (after tax) share
of net income from its equity investment in Brazil was due to higher
margins and foreign currency gains, partially offset by the mark-to-
market loss on an embedded derivative in the electric power contract
and higher plant financing costs.

Six Months Ended June 30, 2003 and 2002

Electric

     Electric earnings increased as a result of higher average sales
for resale prices of 46 percent, due to stronger sales for resale
markets, and higher retail sales revenues, primarily due to higher
retail sales volumes of 7 percent, largely to commercial,
residential and large industrial customers.  Partially offsetting
the earnings increase was higher operation and maintenance expense,
largely higher payroll costs and higher costs related to planned
maintenance outages at two generating stations.  Increased purchased
power costs and decreased sales for resale volumes of 12 percent,
both primarily related to planned maintenance outages at two
generating stations, also partially offset the earnings increase.

Natural Gas Distribution

     Earnings at the natural gas distribution business decreased as
a result of higher operation and maintenance expense, primarily due
to higher payroll and employee benefit-related costs, and decreased
returns on natural gas held in storage.  Partially offsetting the
earnings decline were higher retail sales rates, the result of rate
increases in Minnesota, Montana, North Dakota and Wyoming, as
previously discussed.  The pass-through of higher natural gas prices
largely resulted in the increase in sales revenues and purchased
natural gas sold.

Utility Services

     Utility services earnings increased as a result of the absence
in 2003 of a 2002 write off of receivables and an unfavorable
settlement of a billing dispute, as previously discussed.  Higher
line construction margins in the Northwest region, lower selling,
general and administrative expenses and higher equipment sale
margins also added to the increase in earnings.  Partially
offsetting the earnings increase were lower inside electrical
margins in the Central and Northwest regions, lower margins in the
Rocky Mountain region and lower line construction margins in the
Southwest and Central regions.  Lower margins are a reflection of
the continuing effects of the soft economy and the downturn in the
telecommunications market.

Pipeline and Energy Services

     Earnings at the pipeline and energy services business increased
as a result of higher gathering volumes of 12 percent and higher
transportation revenues, primarily higher reservation fees resulting
from an increase in firm services, offset in part by lower
transportation volumes, largely lower volumes transported to
storage.  Higher storage revenues also added to the earnings
increase.  Partially offsetting the earnings increase was higher
interest expense due to higher average debt balances.  The increase
in energy services revenue and the related increase in purchased
natural gas sold were largely due to an increase in natural gas
prices since the comparable period last year.

Natural Gas and Oil Production

     Natural gas and oil production earnings decreased largely due
to the 2002 compromise agreement gain of $27.4 million ($16.6
million after tax), included in 2002 operating revenues, and the
$12.7 million ($7.7 million after tax) noncash transition charge in
2003, reflecting the cumulative effect of an accounting change, as
discussed in Note 18 and Note 8 of Notes to Consolidated Financial
Statements, respectively.  Also contributing to the earnings decline
were increased depreciation, depletion and amortization expense due
to higher natural gas production volumes and higher rates.
Increased operation and maintenance expense, primarily higher lease
operating expenses resulting largely from the expansion of coalbed
natural gas production, and higher interest expense, due primarily
to higher average debt balances, contributed to the decrease in
earnings.  Higher general and administrative costs and decreased oil
production of 6 percent, also contributed to the earnings decline.
Largely offsetting the decrease in earnings were higher realized
natural gas prices of 56 percent, higher natural gas production of
20 percent, largely from operated properties in the Rocky Mountain
area, and higher average realized oil prices of 29 percent.

Construction Materials and Mining

     Construction materials and mining earnings increased due to
increased aggregate volumes and margins, higher construction
activity due to a large harbor-deepening project in southern
California, and increased ready-mixed concrete and cement volumes,
all at existing operations.  Partially offsetting the increase in
earnings were higher selling, general and administrative costs,
higher depreciation, depletion and amortization expense due to
higher aggregate volumes produced and higher property, plant and
equipment balances, and higher asphalt oil and fuel costs.

Independent Power Production and Other

     Earnings for the independent power production business
increased largely from domestic businesses acquired since the
comparable period last year, partially offset by higher interest
expense, resulting from higher average debt balances relating to
these acquisitions.  The Brazilian operations also contributed to
the earnings increase.  The Company's $1.8 million (after tax) share
of net income from its equity investment in Brazil was due to higher
margins and foreign currency gains, partially offset by the mark-to-
market loss on an embedded derivative in the electric power contract
and higher plant financing costs.

Risk Factors and Cautionary Statements that May Affect Future Results

     The Company is including the following factors and cautionary
statements in this Form 10-Q 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, or on behalf of, the Company.  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 that are other than statements of historical facts.  From
time to time, the Company may publish or otherwise make available
forward-looking statements of this nature, including statements
contained within Prospective Information.  All such subsequent
forward-looking statements, whether written or oral and whether made
by or on behalf of the Company, are also expressly qualified by
these factors and cautionary statements.

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

     Any forward-looking statement contained in this document speaks
only as of the date on which such statement is made, and the Company
undertakes no obligation to update any forward-looking statement or
statements to reflect events or circumstances that occur after the
date on which such 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 such factors, nor
can it assess the effect of each such factor on the Company's
business or the extent to which any such 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 the Company's financial condition.
These factors and the other matters discussed herein are important
factors that could cause actual results or outcomes for the Company
to differ materially from those discussed in the forward-looking
statements included elsewhere in this document.

Economic Risks

The recent events leading to the current adverse economic
environment may have a general negative impact on the Company's
future revenues and may result in a goodwill impairment for
Innovatum, Inc., an indirect wholly owned subsidiary of the Company
(Innovatum).

     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 the Company's products and services.

     Innovatum, which 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 June 30, 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, rapid changes in technology, competitors and
potential new customers.

The Company relies on financing sources and capital markets.
The Company's inability to access financing may impair its ability
to execute the Company's business plans, make capital expenditures
or pursue acquisitions that the Company may otherwise rely on for
future growth.

     The Company relies 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 the Company is not
able to access capital at competitive rates, the ability to
implement its business plans may be adversely affected.  Market
disruptions or a downgrade of the Company's credit ratings may
increase the cost of borrowing or adversely affect its ability to
access one or more financial markets.  Such disruptions could
include:

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

The Company's 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 the Company's operations are subject to extensive
environmental laws and regulations that may increase its costs of
operations, impact or limit its business plans, or expose the
Company to environmental liabilities.  One of the Company's
subsidiaries has been sued in connection with its coalbed natural
gas development activities.

     The Company is subject to extensive environmental laws and
regulations affecting many aspects of its 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 the Company 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.  The
Company 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 the Company.  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 effect
on the Company's results of operations.

     Fidelity 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.

The Company is subject to extensive government regulations that
may have a negative impact on its business and its results of
operations.

     The Company is 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 the Company's
operating environment and may affect its ability to recover costs
from its customers.  The Company is 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 the Company's results of
operations.

Risks Relating to the Company's Independent Power Production Business

There are risks involved with the growth strategies of the
Company's independent power production business.  If the Company is
unable to access markets previously unavailable to a proposed 113-
megawatt coal-fired electric generation station in Montana, it 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.

     The Company's plans to construct a 113-megawatt coal-fired
electric generation station in Montana are pending.  The Company
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, the Company is in the process of accessing markets
previously unavailable to this project and plans to resume
construction in the near future to the extent access to such markets
is secured.  The Company has suspended construction activities
except for those items of a critical nature.  At June 30, 2003, the
Company's investment in this project was approximately $29.6
million.  If it is not economically feasible for the Company to
construct and operate this facility or if alternate markets cannot
be identified, an asset impairment may occur.

Risks Relating to Foreign Operations

The value of the Company's investment in foreign operations may
diminish due to political, regulatory and economic conditions and
changes in currency exchange rates in countries where the Company
does business.

     The Company is subject to political, regulatory and economic
conditions and changes in currency exchange rates in foreign
countries where the Company does business.  Significant changes in
the political, regulatory or economic environment in these countries
could negatively affect the value of the Company's investments
located in these countries.  Also, since the Company is unable to
predict the fluctuations in the foreign currency exchange rates,
these fluctuations may have an adverse impact on the Company's
results of operations.

     The Company's 49 percent equity method 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 the Company's businesses.

     All of the Company's businesses 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 the Company's operations and
revenues.

     The Company's 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, affect the ability to perform services at the utility
services and construction materials and mining businesses and affect
ongoing operation and maintenance activities for the pipeline and
energy services and natural gas and oil production 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 the Company's results of operations and financial condition.

Prospective Information

     The following information includes highlights of the key growth
strategies, projections and certain assumptions for the Company and
its subsidiaries over the next few years and other matters for each
of the Company's businesses.  Many of these highlighted points are
forward-looking statements.  There is no assurance that the
Company's projections, including estimates for growth and increases
in revenues and earnings, will in fact be achieved.  Reference
should be made to assumptions contained in this section as well as
the various important factors listed under the heading Risk Factors
and Cautionary Statements that May Affect Future Results.  Changes
in such assumptions and factors could cause actual future results to
differ materially from targeted growth, revenue and earnings
projections.

MDU Resources Group, Inc.

- - 2003 earnings per common share, diluted, before the cumulative
  effect of the change in accounting for asset retirement obligations
  as required by the adoption of SFAS No. 143, are projected in the
  range of $2.20 to $2.45.  Including the $7.6 million after-tax
  cumulative effect of the accounting change, 2003 earnings per common
  share, diluted, are projected to be in the range of $2.10 to $2.35.

- - The Company expects the percentage of 2003 earnings per common
  share, diluted, after the cumulative effect of an accounting change
  by quarter to be in the following approximate ranges:

  -   Third Quarter - 35 percent to 40 percent
  -   Fourth Quarter - 22 percent to 27 percent

- - The Company will consider issuing equity from time to time to
  keep debt at the nonregulated businesses at no more than 40 percent
  of total capitalization.

- - The Company's long-term compound annual growth goals on
  earnings per share from operations are in the range of 6 percent to
  9 percent.

Electric

- - Montana-Dakota has obtained and holds valid and existing
  franchises authorizing it to conduct its electric operations in all
  of the municipalities it serves where such franchises are required.
  As franchises expire, Montana-Dakota may face increasing competition
  in its service areas, particularly its service to smaller towns,
  from rural electric cooperatives.  Montana-Dakota intends to protect
  its service area and seek renewal of all expiring franchises and
  will continue to take steps to effectively operate in an
  increasingly competitive environment.

- - A new 40-megawatt, natural gas-fueled combustion turbine near
  Glendive, Montana, became operational in late May.  The new plant
  will help the utility provide peak period electrical energy to
  customers on its integrated system in North Dakota, South Dakota and
  Montana.  In addition, the added capacity will allow the company to
  meet its peak load obligation with the regional power pool.  The
  costs of this project are expected to be recovered in rates.

- - Montana-Dakota filed an application with the NDPSC seeking an
  increase in electric retail rates of 9.1 percent above current
  rates.  While Montana-Dakota believes that it should be authorized
  to increase retail rates in the respective amount requested, there
  is no assurance that the increases ultimately allowed will be for
  the full amount requested in the jurisdiction.  For further
  information on the electric rate increase application, see Note 17
  of Notes to Consolidated Financial Statements.

- - Regulatory approval has been received from the NDPSC and the
  SDPUC on the Company's plans to purchase energy from a 20-megawatt
  wind energy farm in North Dakota.  This wind energy farm is expected
  to be on line by late 2003 or early 2004.

- - The Company expects to build an additional 80-megawatts of
  peaking capacity by 2007.  The costs of these projects are expected
  to be recovered in rates and will be used to meet Montana-Dakota's
  need for additional generating capacity.

- - The Company is working with the state of North Dakota to
  determine the feasibility of constructing a 250-megawatt to 500-
  megawatt lignite-fired power plant in western North Dakota.  The
  next preliminary decision on this matter is expected in late 2003.

Natural gas distribution

- - Montana-Dakota and Great Plains have obtained and hold valid
  and existing franchises authorizing them to conduct their natural
  gas operations in all of the municipalities they serve where such
  franchises are required.  As franchises expire, Montana-Dakota and
  Great Plains may face increasing competition in their service areas.
  Montana-Dakota and Great Plains intend to protect their service
  areas and seek renewal of all expiring franchises and will continue
  to take steps to effectively operate in an increasingly competitive
  environment.

- - Annual natural gas throughput for 2003 is expected to be
  approximately 52 million decatherms.

- - Montana-Dakota filed an application with the SDPUC seeking an
  increase in natural gas retail rates of 5.8 percent above current
  rates.  Great Plains filed an application with the MPUC seeking an
  increase in natural gas retail rates of 6.9 percent above current
  rates.  While Montana-Dakota and Great Plains believe that they
  should be authorized to increase retail rates in the respective
  amounts requested, there is no assurance that the increases
  ultimately allowed will be for the full amounts requested in each
  jurisdiction.  For further information on the natural gas rate
  increase applications, see Note 17 of Notes to Consolidated
  Financial Statements.

Utility services

- - 2003 revenues for this segment are expected to be in the range
  of $425 million to $475 million.

- - This segment anticipates margins in 2003 to decrease slightly
  from 2002 levels.  During 2002, a number of factors affected
  earnings, including the write-off of certain receivables and
  restructuring of the engineering function which amounts totaled
  approximately $5.2 million after-tax.

- - This segment's work backlog as of June 30, 2003, was
  approximately $150 million.

Pipeline and energy services

- - In 2003, natural gas throughput from this segment, including
  both transportation and gathering, is expected to increase slightly
  over the 2002 record levels.

- - Pipeline construction has begun in Wyoming on the 253-mile
  Grasslands Pipeline project with construction expected to start soon
  in North Dakota and Montana.  Construction has begun on both a new
  compressor station in western North Dakota and an addition to an
  existing station in Montana, related to this project.  The estimated
  in-service date is November 1, 2003.

- - Innovatum could face a future goodwill impairment based on
  certain economic conditions, as previously discussed in Risk Factors
  and Cautionary Statements that May Affect Future Results.

Natural gas and oil production

- - In 2003, this segment expects a combined natural gas and oil
  production increase of approximately 15 percent over 2002 record
  levels.  Currently, this segment's gross daily operated natural gas
  production is approximately 130,000 Mcf per day.

- - This segment continues to expand its operated production.
  Natural gas production from operated properties was 73 percent and
  66 percent for the six months ended June 30, 2003 and 2002,
  respectively.

- - This segment expects to drill more than 400 wells in 2003.  At
  June 30, 2003, 158 wells had been drilled.

- - This segment had approximately 150 wells in process related to
  its coalbed natural gas development in the Powder River Basin in
  Montana and Wyoming that were not producing natural gas or water at
  June 30, 2003, but may begin producing either natural gas or water
  in the future.

- - Estimates for natural gas prices in the Rocky Mountain region
  for August through December 2003, reflected in the Company's 2003
  earnings guidance, are in the range of $3.00 to $3.50 per Mcf.  The
  Company's estimates for natural gas prices on the NYMEX for August
  through December 2003, reflected in the Company's 2003 earnings
  guidance, are in the range of $4.25 to $4.75 per Mcf. During 2002,
  more than half of this segment's natural gas production was priced
  using Rocky Mountain or other non-NYMEX prices.

- - Estimates of NYMEX crude oil prices for July through December
  2003, reflected in the Company's 2003 earnings guidance, are in the
  range of $22 to $27 per barrel.

- - The Company has hedged a portion of its 2003 production
  primarily using collars that establish both a floor and a cap.  The
  Company has entered into agreements representing approximately 45
  percent to 50 percent of 2003 estimated annual natural gas
  production.  The agreements are at various indices and range from a
  low CIG index of $2.94 to a high Ventura index of $4.76 per Mcf.
  CIG is an index pricing point related to Colorado Interstate Gas
  Co.'s system and Ventura is an index pricing point related to
  Northern Natural Gas Co.'s system.

- - The Company has hedged a portion of its 2003 oil production.
  The Company has entered into agreements at NYMEX prices with floors
  of $24.50 and caps as high as $28.12, representing approximately 30
  percent to 35 percent of 2003 estimated annual oil production.

- - The Company has begun hedging a portion of its 2004 estimated
  annual natural gas production.  The Company has entered into
  agreements representing approximately 10 percent to 15 percent of
  2004 estimated annual natural gas production.  The agreements are at
  various indices and range from a low CIG index of $3.75 to a high
  NYMEX index of $5.20 per Mcf.

- - Fidelity 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.

  In one such case, the United States District Court in Billings,
  Montana (Federal District Court) held that water produced in
  association with coalbed natural gas and discharged into rivers
  and streams was not a pollutant under the Federal Clean Water Act
  and that state statutes exempt such unaltered groundwater from
  Montana Pollution Discharge Elimination System permit
  requirements.  On April 10, 2003, the United States Circuit Court
  of Appeals for the Ninth Circuit (Circuit Court) reversed the
  Federal District Court's decision.  Fidelity filed a petition for
  a writ of certiorari with the United States Supreme Court on
  August 8, 2003.  Fidelity believes the ultimate outcome of the
  proceeding will not have a material effect on its existing coalbed
  natural gas operations or future development of its coalbed
  natural gas properties.  In the event a penalty is ultimately
  imposed in that proceeding, Fidelity believes it will be minimal
  because any unpermitted discharges were of small amounts, were for
  a short duration, were quickly remediated and are now fully
  permitted.

  Fidelity believes the ultimate outcome of other lawsuits filed in
  connection with its coalbed natural gas development would not have
  a material effect on its existing coalbed natural gas operations,
  but could have a material effect on Fidelity's future development
  of its coalbed natural gas properties.

  For further information on these proceedings, see Risk Factors and
  Cautionary Statements that May Affect Future Results in this Form
  10-Q.

Construction materials and mining

- - Excluding the effects of potential future acquisitions,
  aggregate and ready-mixed concrete volumes are expected to increase
  over record levels achieved in 2002, while asphalt volumes are
  expected to be comparable to 2002 levels.

- - Revenues for this segment in 2003 are expected to increase by
  approximately 10 percent as compared to 2002 record levels.

- - As of mid-July 2003, this segment had $497 million in work
  backlog.

- - On July 11, 2003, this segment completed the acquisition of a
  privately held construction materials and services company serving
  East Central Texas.  The company supplies and places ready-mixed
  concrete, asphalt, crushed stone and sand and gravel for highways,
  subdivisions and a variety of other projects in 27 central Texas
  counties.  In 2002, the acquired company had annual revenues of
  about $87 million.  The acquisition is expected to be accretive to
  earnings per share.

- - Four of the five labor contracts that Knife River was
  negotiating, as reported in Items 1 and 2 - Business and Properties
  - General in the Company's 2002 Form 10-K, have been ratified and
  the one remaining contract is being negotiated.  The Company
  considers its relations with its employees to be satisfactory.

Independent power production and other

- - 2003 earnings projections for independent power production and other
  include the estimated results from the wind-powered electric
  generation facility in California, the natural gas-fired generating
  facilities in Colorado, and the Company's 49 percent ownership in a
  220-megawatt natural gas-fired generation project in Brazil.
  Earnings are expected to be in the range of $9 million to $14
  million in 2003.

- - The Company's plans to construct a 113-megawatt coal-fired
  electric generation station in Montana are pending, as previously
  discussed in Risk Factors and Cautionary Statements that May Affect
  Future Results.

New Accounting Standards

     In June 2001, the FASB approved SFAS No. 141, "Business
Combinations," which requires the purchase method of accounting for
business combinations initiated after June 30, 2001 and eliminates
the pooling-of-interests method.  In June 2001, the FASB also
approved SFAS No. 142, "Goodwill and Other Intangible Assets," which
discontinues the practice of amortizing goodwill and indefinite
lived intangible assets and initiates an annual review for
impairment.  Intangible assets with a determinable useful life will
continue to be amortized over that period.  The amortization
provisions apply to goodwill and intangible assets acquired after
June 30, 2001.  SFAS No. 141 and SFAS No. 142 clarify that more
assets should be distinguished and classified between tangible and
intangible.  The Company did not change or reclassify contractual
mineral rights included in property, plant and equipment related to
its natural gas and oil production business upon adoption of SFAS
No. 142.  The Company has included such mineral rights as part of
property, plant and equipment under the full cost method of
accounting for natural gas and oil properties.  The SEC has recently
questioned under SFAS No. 142 whether contractual mineral rights
should be classified as intangible rather than as part of property,
plant and equipment and has referred this accounting matter to the
Emerging Issues Task Force and is continuing its dialog with the
FASB staff.  The resolution of this matter may result in certain
reclassifications to the Company's Consolidated Balance Sheet, as
well as changes to the Company's Notes to Consolidated Financial
Statements in the future.  The applicable provisions of SFAS No. 141
and SFAS No. 142 only impact balance sheet and associated footnote
disclosure, so any reclassifications that might be required in the
future will not impact the Company's cash flows or results of
operations.  The Company believes that the resolution of this matter
will not have a material effect on the Company's financial position
because the mineral rights acquired by its natural gas and oil
production business after the June 30, 2001, effective date are not
material.

     In June 2001, the FASB approved SFAS No. 143, "Accounting for
Asset Retirement Obligations."  Upon adoption of SFAS No. 143, the
Company recorded a 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 tax benefit of $4.8
million).

     In April 2002, the FASB approved SFAS No. 145, "Rescission of
FASB Statements No. 4, 44 and 64, Amendment of FASB Statement No.
13, and Technical Corrections."  The adoption of SFAS No. 145 did
not have a material effect on the Company's financial position or
results of operations.

     In November 2002, the FASB issued FASB Interpretation No. 45,
"Guarantor's Accounting and Disclosure Requirements for Guarantees,
Including indirect Guarantees of Indebtedness of Others" (FIN 45).
The Company will apply the initial recognition and initial
measurement provisions of FIN 45 to guarantees issued or modified
after December 31, 2002.

     In January 2003, the FASB issued FASB Interpretation No. 46,
"Consolidation of Variable Interest Entities" (FIN 46).  FIN 46 is
effective for the first fiscal year or interim period beginning
after June 15, 2003, for variable interest entities created before
February 1, 2003.  The Company will prospectively apply the
provisions of FIN 46 that were effective January 31, 2003.  The
adoption of FIN 46 did not have a material effect on the Company's
financial position or results of operations.

     In April 2003, the FASB issued SFAS No. 149, "Amendment of
Statement 133 on Derivative Instruments and Hedging Activities."
SFAS No. 149 is generally effective for contracts entered into or
modified after June 30, 2003, and for hedging relationships
designated after June 30, 2003.  The Company does not expect SFAS
No. 149 to have a material effect on its financial position or
results of operations.

     In May 2003, the FASB issued SFAS No. 150, "Accounting for
Certain Financial Instruments with Characteristics of Both
Liabilities and Equity."  The Company will apply SFAS No. 150 to any
financial instruments entered into or modified after May 31, 2003.
The Company is currently evaluating the effect of SFAS No. 150 for
financial instruments entered into on or before May 31, 2003, on its
financial position and results of operations.

     For further information on SFAS No. 143, SFAS No. 145, FIN 45,
FIN 46, SFAS No. 149 and SFAS No. 150 see Note 8 of Notes to
Consolidated Financial Statements.

Critical Accounting Policies

     The Company's critical accounting policies include impairment
of long-lived assets and intangibles, impairment testing of natural
gas and oil properties, revenue recognition, derivatives, purchase
accounting, accounting for the effects of regulation and use of
estimates.  There are no material changes in the Company's critical
accounting policies from those reported in the Company's Annual
Report on Form 10-K for the year ended December 31, 2002.  For more
information on critical accounting policies, see Part II, Item 7 in
the Company's Annual Report on Form 10-K for the year ended December
31, 2002.

Liquidity and Capital Commitments

Cash flows

Operating activities --

     Cash flows provided by operating activities in the first six
months of 2003 increased $66.7 million from the comparable 2002
period, the result of an increase in cash from working capital items
of $17.7 million and higher depreciation, depletion and amortization
expense of $17.0 million, resulting largely from increased property,
plant and equipment balances and higher production volumes.  An
increase in net income of $15.0 million and the cumulative effect of
an accounting change of $7.6 million also added to the increase of
cash flows provided by operating activities.

Investing activities --

     Cash flows used in investing activities in the first six months
of 2003 increased $111.2 million compared to the comparable 2002
period, the result of an increase in net capital expenditures
(capital expenditures; acquisitions, net of cash acquired; and net
proceeds from the sale or disposition of property) of $114.5
million, slightly offset by an increase in proceeds from notes
receivable of $3.8 million.  Net capital expenditures exclude the
noncash transactions related to acquisitions, including the issuance
of the Company's equity securities.  The noncash transactions were
$4.9 million and $41.8 million for the first six months of 2003 and
2002, respectively.

Financing activities --

     Cash flows provided by financing activities in the first six
months of 2003 increased $36.7 million compared to the comparable
2002 period, due to an increase in the issuance of long-term debt of
$135.8 million.  The increase in the repayment of long-term debt of
$77.1 million and the net decrease of short-term borrowings of $19.0
million, partially offset the increase in cash provided by financing
activities.

Defined benefit pension plans

     The Company has qualified noncontributory defined benefit
pension plans (Pension Plans).  There are no material changes in the
Company's Pension Plans from those reported in the Company's Annual
Report on Form 10-K for the year ended December 31, 2002.  For
further information on the Company's Pension Plans, see Part II,
Item 7 in the Company's Annual Report on Form 10-K for the year
ended December 31, 2002.

Capital expenditures

     Net capital expenditures, including the issuance of the
Company's equity securities, for the first six months of 2003 were
$243.9 million and are estimated to be approximately $525 million
for the year 2003.  Estimated capital expenditures include those
for:

  -  Completed acquisitions
  -  System upgrades, including a 40-megawatt natural gas-fired
     peaking unit, as previously discussed
  -  Routine replacements
  -  Service extensions
  -  Routine equipment maintenance and replacements
  -  Land and building improvements
  -  Pipeline and gathering expansion projects, including a 253-mile
     pipeline, as previously discussed
  -  The further enhancement of natural gas and oil production and
     reserve growth
  -  Power generation opportunities, including certain construction
     costs for a 113-megawatt coal-fired electric generation station,
     as previously discussed
  -  Other growth opportunities

     Approximately 35 percent of estimated 2003 net capital
expenditures are for completed acquisitions.  The Company continues
to evaluate potential future acquisitions and other growth
opportunities; however, they are dependent upon the availability of
economic opportunities and, as a result, actual acquisitions and
capital expenditures may vary significantly from the estimated 2003
capital expenditures referred to above.  It is anticipated that the
funds required for capital expenditures will be met from various
sources.  These sources include internally generated funds,
commercial paper credit facilities at Centennial and MDU Resources,
as described below, and through the issuance of long-term debt and
the Company's equity securities.

     The estimated 2003 capital expenditures referred to above
include completed 2003 acquisitions involving a wind-powered
electric generation facility in California and construction
materials and mining businesses in Montana, North Dakota and Texas.
Pro forma financial amounts reflecting the effects of the above
acquisitions are not presented as such acquisitions were not
material to the Company's financial position or results of
operations.

Capital resources

     Certain debt instruments of the Company and its subsidiaries,
including those discussed below, contain restrictive covenants, all
of which the Company and its subsidiaries were in compliance with at
June 30, 2003.

MDU Resources Group, Inc.

     The Company has unsecured short-term bank lines of credit from
various banks totaling $21 million and a revolving credit agreement
with various banks totaling $50 million at June 30, 2003.  The bank
lines of credit provide for commitment fees at varying rates.  There
were no amounts outstanding under the bank lines of credit or the
credit agreement at June 30, 2003.  The bank lines of credit and the
credit agreement support the Company's $75 million commercial paper
program.  Under the Company's commercial paper program, $30.0
million was outstanding at June 30, 2003.  The commercial paper
borrowings are classified as long-term debt as the Company intends
to refinance these borrowings on a long-term basis through continued
commercial paper borrowings and as further supported by the credit
agreement.  On July 18, 2003, the Company increased the credit
agreement to $90 million and extended the maturity date of this
agreement to July 18, 2006.

     The Company's goal is to maintain acceptable credit ratings in
order to access the capital markets through the issuance of
commercial paper.  If the Company were to experience a minor
downgrade of its credit ratings, it would not anticipate any change
in its ability to access the capital markets.  However, in such
event, the Company would expect a nominal basis point increase in
overall interest rates with respect to its cost of borrowings.  If
the Company were to experience a significant downgrade of its credit
ratings, which it does not currently anticipate, it may need to
borrow under its credit agreement and/or bank lines of credit.

     To the extent the Company needs to borrow under its credit
agreement and/or bank lines of credit, it would be expected to incur
increased annualized interest expense on its variable rate debt of
approximately $45,000 (after tax) based on June 30, 2003, variable
rate borrowings.  Based on the Company's overall interest rate
exposure at June 30, 2003, this change would not have a material
effect on the Company's results of operations or cash flows.

     Prior to the maturity of the credit agreement and the bank
lines of credit, the Company plans to negotiate the extension or
replacement of these agreements that provide credit support to
access the capital markets.  In the event the Company was unable to
successfully negotiate the credit agreement and/or the bank lines of
credit, or in the event the fees on such facilities became too
expensive, which it does not currently anticipate, the Company would
seek alternative funding.  One source of alternative funding might
involve the securitization of certain Company assets.

     In order to borrow under the Company's credit agreement, the
Company must be in compliance with the applicable covenants and
certain other conditions.  The significant covenants include maximum
leverage ratios, minimum interest coverage ratio, limitation on sale
of assets and limitation on investments.  The Company was in
compliance with these covenants and met the required conditions at
June 30, 2003.  In the event the Company does not comply with the
applicable covenants and other conditions, alternative sources of
funding may need to be pursued, as previously described.

     Currently, there are no credit facilities that contain cross-
default provisions between the Company and any of its subsidiaries.

     The Company's issuance of first mortgage debt is subject to
certain restrictions imposed under the terms and conditions of its
Indenture of Mortgage.  Generally, those restrictions require the
Company to pledge $1.43 of unfunded property to the trustee for each
dollar of indebtedness incurred under the Indenture and that annual
earnings (pretax and before interest charges), as defined in the
Indenture, equal at least two times its annualized first mortgage
bond interest costs.  Under the more restrictive of the two tests,
as of June 30, 2003, the Company could have issued approximately
$339 million of additional first mortgage bonds.

     The Company's coverage of fixed charges including preferred
dividends was 4.9 times and 4.8 times for the twelve months ended
June 30, 2003 and December 31, 2002, respectively.  Additionally,
the Company's first mortgage bond interest coverage was 8.1 times
and 7.7 times for the twelve months ended June 30, 2003 and December
31, 2002, respectively.  Common stockholders' equity as a percent of
total capitalization was 58 percent and 60 percent at June 30, 2003
and December 31, 2002, respectively.

Centennial Energy Holdings, Inc.

     Centennial has a revolving credit agreement with various banks
that supports $330 million of Centennial's $350 million commercial
paper program.  There were no outstanding borrowings under the
Centennial credit agreement at June 30, 2003.  Under the Centennial
commercial paper program, $78.1 million was outstanding at June 30,
2003.  The Centennial commercial paper borrowings are classified as
long-term debt as Centennial intends to refinance these borrowings
on a long-term basis through continued Centennial commercial paper
borrowings and as further supported by the Centennial credit
agreement, which allows for subsequent borrowings up to a term of
one year.  Centennial intends to renew the Centennial credit
agreement, which expires September 26, 2003.

     Centennial has an uncommitted long-term master shelf agreement
that allows for borrowings of up to $400 million.  Under the terms
of the master shelf agreement, $394.6 million was outstanding at
June 30, 2003.  To meet potential future financing needs, Centennial
may pursue other financing arrangements, including private and/or
public financing.

     Centennial entered into a $125 million note purchase agreement
on June 27, 2003.  The $125 million in proceeds was used to pay down
Centennial commercial paper program borrowings.

     Centennial's goal is to maintain acceptable credit ratings in
order to access the capital markets through the issuance of
commercial paper.  If Centennial were to experience a minor
downgrade of its credit ratings, it would not anticipate any change
in its ability to access the capital markets.  However, in such
event, Centennial would expect a nominal basis point increase in
overall interest rates with respect to its cost of borrowings.  If
Centennial were to experience a significant downgrade of its credit
ratings, which it does not currently anticipate, it may need to
borrow under its committed bank lines.

     To the extent Centennial needs to borrow under its committed
bank lines, it would be expected to incur increased annualized
interest expense on its variable rate debt of approximately $117,000
(after tax) based on June 30, 2003, variable rate borrowings.  Based
on Centennial's overall interest rate exposure at June 30, 2003,
this change would not have a material effect on the Company's
results of operations or cash flows.

     On an annual basis, Centennial negotiates the extension or
replacement of the Centennial credit agreement that provides credit
support to access the capital markets.  In the event Centennial was
unable to successfully negotiate the credit agreement, or in the
event the fees on such facility became too expensive, which
Centennial does not currently anticipate, it would seek alternative
funding.  One source of alternative funding might involve the
securitization of certain Centennial assets.

     In order to borrow under Centennial's credit agreement and the
Centennial uncommitted long-term master shelf agreement, Centennial
and certain of its subsidiaries must be in compliance with the
applicable covenants and certain other conditions.  The significant
covenants include maximum capitalization ratios, minimum interest
coverage ratios, minimum consolidated net worth, limitation on
priority debt, limitation on sale of assets and limitation on loans
and investments.  Centennial and such subsidiaries were in
compliance with these covenants and met the required conditions at
June 30, 2003.  In the event Centennial or such subsidiaries do not
comply with the applicable covenants and other conditions,
alternative sources of funding may need to be pursued as previously
described.

     Certain of Centennial's financing agreements contain cross-
default provisions.  These provisions state that if Centennial or
any subsidiary of Centennial fails to make any payment with respect
to any indebtedness or contingent obligation, in excess of a
specified amount, under any agreement that causes such indebtedness
to be due prior to its stated maturity or the contingent obligation
to become payable, the applicable agreements will be in default.
Certain of Centennial's financing agreements and Centennial's
practice limit the amount of subsidiary indebtedness.

Centennial Energy Resources International Inc

     Centennial Energy Resources International Inc (Centennial
International), an indirect wholly owned subsidiary of the Company,
had a short-term credit agreement that allowed for borrowings of
up to $10 million.  Under this agreement, $5.5 million was
outstanding at June 30, 2003.  On June 30, 2003, Centennial
International extended this agreement through September 30, 2003,
and lowered the amount of allowed borrowings from $25 million to $10
million.  This agreement was terminated on July 11, 2003.
Centennial had guaranteed this short-term credit agreement.

Williston Basin Interstate Pipeline Company

     Williston Basin has an uncommitted long-term master shelf
agreement that allows for borrowings of up to $100 million.  Under
the terms of the master shelf agreement, $30.0 million was
outstanding at June 30, 2003.

     In order to borrow under Williston Basin's uncommitted long-
term master shelf agreement, it must be in compliance with the
applicable covenants and certain other conditions.  The significant
covenants include limitation on consolidated indebtedness,
limitation on priority debt, limitation on sale of assets and
limitation on investments.  Williston Basin was in compliance with
these covenants and met the required conditions at June 30, 2003.
In the event Williston Basin does not comply with the applicable
covenants and other conditions, alternative sources of funding may
need to be pursued.

Contractual obligations and commercial commitments

     There are no material changes in the Company's contractual
obligations on operating leases and purchase commitments from those
reported in the Company's Annual Report on Form 10-K for the year
ended December 31, 2002.

     The Company's contractual obligations on long-term debt at June
30, 2003, increased $114.8 million or 14 percent from December 31,
2002, primarily due to acquisitions and other corporate purposes.
At June 30, 2003, the Company's commitments under these obligations
for the twelve months ended June 30, were as follows:

                 2004   2005  2006   2007   2008  Thereafter  Total
                                  (In millions)

Long-term debt  $34.9 $196.8 $25.5 $180.7 $110.1    $408.5   $956.5

     For more information on contractual obligations and commercial
commitments, see Part II, Item 7 in the Company's Annual Report on
Form 10-K for the year ended December 31, 2002.

     Centennial has financial guarantees outstanding at June 30,
2003.  These guarantees pertain to Centennial's guarantee of certain
obligations in connection with the natural gas-fired electric
generation station in Brazil and as of June 30, 2003, are
approximately $57.1 million.  As of June 30, 2003, with respect to
these guarantees, there was approximately $2.1 million outstanding
through 2003, $12.3 million outstanding through 2004 and $42.7
million outstanding through 2006.  These guarantees are not
reflected on the Consolidated Balance Sheets.

     On June 17, 2003, MPX entered into a five-year credit agreement
with the U.S. Export-Import Bank under which MPX borrowed $50.6
million.  MPX received the proceeds of this loan on July 10, 2003,
and used the funds to pay outstanding bank borrowings.  Centennial
and EBX have jointly and severally guaranteed repayment of this
loan.  Following this refinancing, guarantees with respect to
approximately $26.4 million will terminate upon MPX meeting certain
financial covenants under the prior financing agreements.

     For more information on these guarantees, see Note 18 of Notes
to Consolidated Financial Statements.

     As of June 30, 2003, Centennial was contingently liable for
performance of certain of its subsidiaries under approximately $302
million of surety bonds.  These bonds are principally for
construction contracts and reclamation obligations of these
subsidiaries, entered into in the normal course of business.
Centennial indemnifies the respective surety bond companies against
any exposure under the bonds.  A large portion of these contingent
commitments expire in 2003, however Centennial will likely continue
to enter into surety bonds for its subsidiaries in the future.  The
surety bonds were not reflected on the Consolidated Balance Sheets.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     The Company is exposed to the impact of market fluctuations
associated with commodity prices, interest rates and foreign
currency.  The Company has policies and procedures to assist in
controlling these market risks and utilizes derivatives to manage a
portion of its risk.

Commodity price risk --

     A subsidiary of the Company utilizes natural gas and oil price
swap and collar agreements to manage a portion of the market risk
associated with fluctuations in the price of natural gas and oil on
the subsidiary's forecasted sales of natural gas and oil production.
For more information on commodity price risk, see Part II, Item 7A
in the Company's Annual Report on Form 10-K for the year ended
December 31, 2002, and Note 12 of Notes to Consolidated Financial
Statements in this Form 10-Q.

     The following table summarizes hedge agreements entered into by
a subsidiary of the Company, as of June 30, 2003.  These agreements
call for the subsidiary to receive fixed prices and pay variable
prices.

Interest rate risk --

     There are no material changes to interest rate risk faced by
the Company from those reported in the Company's Annual Report on
Form 10-K for the year ended December 31, 2002.  For more
information on interest rate risk, see Part II, Item 7A in the
Company's Annual Report on Form 10-K for the year ended December 31,
2002.

Foreign currency risk --

     MDU Brasil has a 49 percent equity investment in a 220-megawatt
natural gas-fired electric generation project (Project) in Brazil,
which has a portion of its borrowings and payables denominated in
U.S. dollars.  MDU Brasil has exposure to currency exchange risk as
a result of fluctuations in currency exchange rates between the U.S.
dollar and the Brazilian real.  The functional currency for the
Project is the Brazilian real.  For further information on this
investment, see Note 10 of Notes to Consolidated Financial
Statements.

     MDU Brasil's equity income from this Brazilian investment is
impacted by fluctuations in currency exchange rates on transactions
denominated in a currency other than the Brazilian real, including
the effects of changes in currency exchange rates with respect to
the Project's U.S. dollar denominated obligations, excluding a U.S.
dollar denominated loan from Centennial International as discussed
below.  At June 30, 2003, these U.S. dollar denominated obligations
approximated $71.2 million.  If, for example, the value of the
Brazilian real decreased in relation to the U.S. dollar by 10
percent, MDU Brasil, with respect to its interest in the Project,
would record a foreign currency transaction loss in net income of
approximately $3.2 million based on the above U.S. dollar
denominated obligations at June 30, 2003.  The Project also had
US$11.4 million of Brazilian real denominated obligations at
June 30, 2003.

     Adjustments attributable to the translation from the Brazilian
real to the U.S. dollar for assets, liabilities, revenues and
expenses were recorded in accumulated other comprehensive income
(loss) at June 30, 2003.  Foreign currency translation adjustments
on the Project's U.S. dollar denominated borrowings payable to the
subsidiary of $20.0 million at June 30, 2003, are recorded in
accumulated other comprehensive income (loss).

     Centennial International's investment in this Project at June
30, 2003, was $20.6 million.  Centennial has guaranteed Project
obligations and loans of approximately $57.1 million as of June 30,
2003.

     A portion of the Project's foreign currency exchange risk is
being managed through contractual provisions, which are largely
indexed to the U.S. dollar, contained in the Project's power
purchase agreement with Petrobras.  In addition, a portion of the
Project's foreign currency risk on interest payments on U.S. dollar
denominated obligations is being managed through the utilization of
foreign currency hedging.  At June 30, 2003, the Project had foreign
currency forward contracts with a notional amount of approximately
$2.0 million at a weighted average rate of R$3.006, which expired on
July 15, 2003, and approximately $2.3 million at a weighted average
rate of R$3.115, which expire on October 15, 2003.  The Company's 49
percent share of the fair value of these forward contracts at June
30, 2003, was approximately $82,000.

ITEM 4.  CONTROLS AND PROCEDURES

     The following information includes the evaluation of disclosure
controls and procedures by the Company's chief executive officer and
the chief financial officer, along with any significant changes in
internal controls of the Company.

Evaluation of disclosure controls and procedures

     The term "disclosure controls and procedures" is defined in
Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934
(Exchange Act).  These rules refer to the controls and other
procedures of a company that are designed to ensure that information
required to be disclosed by a company in the reports that it files
under the Exchange Act is recorded, processed, summarized and
reported within required time periods.  The Company's chief
executive officer and chief financial officer have evaluated the
effectiveness of the Company's disclosure controls and procedures as
of the period covered by this report, and, they have concluded that,
as of this period, such controls and procedures were effective to
accomplish those tasks.

Changes in internal controls

     The Company maintains a system of internal accounting controls
that are designed to provide reasonable assurance that the Company's
transactions are properly authorized, the Company's assets are
safeguarded against unauthorized or improper use, and the Company's
transactions are properly recorded and reported to permit
preparation of the Company's financial statements in conformity with
generally accepted accounting principles in the United States of
America.  There were no changes in the Company's internal control
over financial reporting that occurred during the period covered by
this report that have materially affected, or are reasonable likely
to materially affect, the Company's internal control over financial
reporting.


                    PART II -- OTHER INFORMATION

Item 1.  LEGAL PROCEEDINGS

     On July 28, 2003, the motion to amend the class petition in the
Quinque legal proceeding was granted by the State District Court for
Stevens County, Kansas, and as a result Williston Basin and Montana-
Dakota are no longer defendants in this proceeding.

     For more information on the above legal action see Note 18 of
Notes to Consolidated Financial Statements.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

     Between April 1, 2003 and June 30, 2003, the Company issued
133,996 shares of Common Stock, $1.00 par value, and the Preference
Share Purchase Rights appurtenant thereto, as part of the
consideration paid by the Company for all of the issued and
outstanding capital stock with respect to a business acquired during
this period.  The Common Stock and Rights issued by the Company in
this transaction were issued in a private transaction exempt from
registration under the Securities Act of 1933 pursuant to Section
4(2) thereof, Rule 506 promulgated thereunder, or both.  The classes
of persons to whom these securities were sold were either accredited
investors or other persons to whom such securities were permitted to
be offered under the applicable exemption.

ITEM 5.  OTHER INFORMATION

Properties - Natural Gas and Oil Production - Operating Information
and Part II, Item 7 - Management's Discussion and Analysis of
Financial Condition and Results of Operations - Financial and
Operating Data - Natural Gas and Oil Production in the Company's
Annual Report on Form 10-K for the year ended December 31, 2002.

     Supplemental information on average realized prices (excluding
hedges) related to natural gas and oil interests for 2002, 2001 and
2000, are as follows:

                                         2002       2001       2000

b) Reference is made to Part I, Items 1 and 2 - Business and
Properties - Construction Materials and Mining - Consolidated
Construction Materials and Mining - Reserve Information in the
Company's Annual Report on Form 10-K for the year ended December 31,
2002.

     Reserve estimates are calculated based on the best available
data.  These data are collected from drill holes and other
subsurface investigations as well as investigations of surface
features like mine highwalls and other exposures of the aggregate
reserves.  Mine plans, production history and geologic data are also
utilized to estimate reserve quantities.

     Estimates are based on analyses of the data described above by
experienced mining engineers, operating personnel and consulting
geologists.  Property setbacks and other regulatory restrictions and
limitations are identified to determine the total area available for
mining.  Data described above are used to calculate the thickness of
aggregate materials to be recovered.  Topography associated with
alluvial sand and gravel deposits is typically flat and volumes of
these materials are calculated by simply applying the thickness of
the resource over the areas available for mining.  Volumes are then
converted to tons by using an appropriate conversion factor.
Typically, 1.5 tons per cubic yard in the ground is used for sand
and gravel deposits.

     Topography associated with the hard rock reserves is typically
much more diverse.  Therefore, using available data, a final
topography map is created and computer software is utilized to
compute the volumes between the existing and final topographies.
Volumes are then converted to tons by using an appropriate
conversion factor.  Typically, 2 tons per cubic yard in the ground
is used for hard rock quarries.

     Estimated reserves are probable reserves as defined in
Securities Act Industry Guide 7.  Remaining reserves are based on
estimates of volumes that can be economically extracted and sold to
meet current market and product applications.  The reserve estimates
include only salable tonnage and thus exclude waste materials that
are generated in the crushing and processing phases of the
operation.  Approximately 928 million tons of the 1.1 billion tons
of aggregate reserves are permitted reserves.  The remaining
reserves are on properties that the Company expects will be
permitted for mining under current regulatory requirements.  Some
sites have leases that expire prior to the exhaustion of the
estimated reserves.  The estimated reserve life (years remaining)
anticipates that leases will be renewed to allow sufficient time to
fully recover these reserves.  The data used to calculate the
remaining reserves may require revisions in the future to account
for changes in customer requirements and unknown geological
occurrences.  The years remaining were calculated by dividing
remaining reserves by current year sales.  Actual useful lives of
these reserves will be subject to, among other things, fluctuations
in customer demand, customer specifications, geological conditions
and changes in mining plans.

     The following table sets forth details applicable to the
Company's aggregate reserves under ownership or lease and production
as of and for the years ended December 31, 2002, 2001 and 2000.

     As of December 31, 2002, Knife River had under ownership or
lease, recoverable lignite deposits of approximately 37.8 million
tons.

     The sale of the Company's coal operations in 2001 included
active coal mines in North Dakota and Montana, coal sales
agreements, reserves and mining equipment, and certain development
rights at the Company's former Gascoyne Mine site in North Dakota.
The Company retained ownership of lignite deposits and leases at its
former Gascoyne Mine site in North Dakota, which were not part of
the sale of the coal operations.  The Gascoyne Mine site was closed
in 1995 due to the cancellation of the coal sale contract.  These
lignite deposits are currently not being mined and are not
associated with an operating mine.  These lignite deposits are of a
high moisture content and it is not economical to mine and ship the
lignite to other distant markets.  However, should a power plant be
constructed near the area, the Company may have the opportunity to
participate in supplying lignite to fuel a plant.
