     MDU Resources Group, Inc. (Company) is a diversified natural
resource company which was incorporated under the laws of the State

Schuchart Building, 918 East Divide Avenue, P.O. Box 5650, Bismarck,
North Dakota 58506-5650, telephone (701) 222-7900.

     Montana-Dakota Utilities Co. (Montana-Dakota), a public utility
division of the Company, through the electric and natural gas
distribution segments, generates, transmits and distributes
electricity and distributes natural gas in the northern Great
Plains.  Great Plains Natural Gas Co. (Great Plains), another public
utility division of the Company, distributes natural gas in
southeastern North Dakota and western Minnesota.  These operations
also supply related value-added products and services.

     The Company, through its wholly owned subsidiary, Centennial
Energy Holdings, Inc. (Centennial), owns WBI Holdings, Inc. (WBI
Holdings), Knife River Corporation (Knife River), Utility Services,
Inc. (Utility Services) and Centennial Holdings Capital Corp.
(Centennial Capital).

     WBI Holdings is comprised of the pipeline and energy
     services and the natural gas and oil production segments.
     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 and provides energy-
     related marketing and management services, as well as cable
     and pipeline locating services.  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.

     Knife River mines aggregates and markets crushed stone,

     units but which are consistent with the Company's philosophy
     and growth strategy.  These activities are reflected in the
     pipeline and energy services segment.

     The Company, through its wholly owned subsidiary, MDU Resources

                      MDU RESOURCES GROUP, INC.
                        NOTES TO CONSOLIDATED
                        FINANCIAL STATEMENTS

                       June 30, 2002 and 2001
                             (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, 2001 (2001 Annual Report), and the standards of
     accounting measurement set forth in Accounting Principles Board
     Opinion No. 28 and any amendments thereto adopted by the
     Financial Accounting Standards Board.  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 2001 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.  Allowance for doubtful accounts

          The Company's allowance for doubtful accounts as of
     June 30, 2002 and 2001, and December 31, 2001 was $8.4 million,
     $4.3 million and $5.8 million, respectively.

 3.  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.

 4.  Cash flow information

          Cash expenditures for interest and income taxes were as
     follows:
                                                Six Months Ended
                                                    June 30,
                                                 2002       2001
                                                 (In thousands)

     Interest, net of amount capitalized       $ 19,236   $20,399
     Income taxes                              $ 40,589   $45,754

 5.  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.

 6.  New accounting standards

          In June 2001, the Financial Accounting Standards Board
     (FASB) approved Statement of Financial Accounting Standards No.
     143, "Accounting for Asset Retirement Obligations" (SFAS No.
     143).  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.  The Company will
     adopt SFAS No. 143 on January 1, 2003, but has not yet
     quantified the effects of adopting SFAS No. 143 on its
     financial position or results of operations.

          In April 2002, the FASB approved Statement of Financial
     Accounting Standards No. 145, "Rescission of FASB Statements
     No. 4, 44 and 64, Amendment of FASB Statement No. 13, and
     Technical Corrections" (SFAS No. 145).  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 Accounting Principles Board 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 Company has not yet
     quantified the effects of adopting SFAS No. 145 on its
     financial position or results of operations.

          In June 2002, the Emerging Issues Task Force (EITF)
     adopted the position in EITF Issue No. 02-3, "Recognition and
     Reporting of Gains and Losses on Energy Trading Contracts under
     EITF Issues No. 98-10, 'Accounting for Contracts Involved in
     Energy Trading and Risk Management Activities,' and No. 00-17,
     'Measuring the Fair Value of Energy-Related Contracts in
     Applying Issue No. 98-10'" (EITF No. 02-3) that mark-to-market
     gains and losses on energy trading contracts should be reported
     net in the income statement whether or not settled physically in
     financial statements issued for periods ending after July 15, 2002.
     EITF No. 02-3 states that all comparative financial statements
     should be reclassified to conform to this consensus.  Although
     this new accounting guidance will require the Company's mark-to-
     market gains and losses on energy trading contracts to be shown
     net on the income statement, it is not expected to impact the
     overall financial position or results of operations of the Company.
     The Company will apply this consensus to financial statements issued
     for periods ending after July 15, 2002, but has not yet quantified
     the financial statement effect from this guidance.

          In June 2002, the FASB approved Statement of Financial
     Accounting Standards No. 146, "Accounting for Costs Associated
     with Exit or Disposal Activities" (SFAS No. 146).  SFAS No. 146
     addresses financial accounting and reporting for costs
     associated with exit or disposal activities and nullifies EITF
     Issue No. 94-3, "Liability Recognition for Certain Employee
     Termination Benefits and Other Costs to Exit an Activity
     (including Certain Costs Incurred in a Restructuring)" (EITF
     No. 94-3).  SFAS No. 146 requires recognition of a liability
     for a cost associated with an exit or disposal activity when
     the liability is incurred, as opposed to when the entity
     commits to an exit plan under EITF No. 94-3. SFAS No. 146 is to
     be applied prospectively to exit or disposal activities
     initiated after December 31, 2002.  The Company has not yet
     determined the effect, if any, of the adoption of SFAS No. 146.

 7.  Derivative instruments

          The Company utilizes derivative instruments, including
     natural gas and oil price swap and natural gas collar
     agreements, to manage a portion of the market risk associated
     with fluctuations in the price of natural gas and oil on the
     Company's forecasted sales of natural gas and oil production.
     The following information should be read in conjunction with
     Note 3 in the Company's Notes to Consolidated Financial
     Statements in the 2001 Annual Report.

          For the three months and six months ended June 30, 2002
     and 2001, the amount of hedge ineffectiveness recognized was
     immaterial.  For the three months and six months ended June 30,
     2002 and 2001, the Company 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.

          As of June 30, 2002, the maximum length of time over which
     the Company is hedging its exposure to the variability in
     future cash flows for forecasted transactions is 18 months.
     The Company estimates that net gains of approximately $2.1
     million will be reclassified from accumulated other
     comprehensive income into earnings, subject to changes in
     natural gas and oil market prices, as the hedged transactions
     affect earnings within the twelve months between July 1, 2002
     and June 30, 2003.

 8.  Comprehensive income

          On January 1, 2001, the Company recorded a cumulative-
     effect adjustment in accumulated other comprehensive loss to
     recognize all derivative instruments designated as hedges at
     fair value.  As of June 30, 2002 and 2001, the Company has
     recorded unrealized gains and losses on natural gas and oil
     price swap and collar agreements and an interest rate swap
     agreement which qualify for hedge accounting.  As of June 30,
     2002, the Company also recorded a minimum pension liability
     adjustment.  These amounts are reflected in the following
     table.

          The Company's comprehensive income, and the components of
     other comprehensive income, net of taxes, were as follows:

                                                  Three Months Ended

     Comprehensive income                         $ 43,755  $ 79,118

 9.  Goodwill and other intangible assets

          In June 2001, the FASB approved Statement of Financial
     Accounting Standards No. 142, "Goodwill and Other Intangible
     Assets" (SFAS No. 142).  SFAS No. 142 changes the accounting
     for goodwill and intangible assets and requires that goodwill
     no longer be amortized but be tested for impairment at least
     annually at the reporting unit level in accordance with SFAS
     No. 142.  Recognized intangible assets with determinable useful
     lives should be amortized over their useful life and reviewed
     for impairment in accordance with Statement of Financial
     Accounting Standards No. 144, "Accounting for the Impairment or
     Disposal of Long-Lived Assets" (SFAS No. 144). The provisions of
     SFAS No. 142 are effective for fiscal years beginning after
     December 15, 2001, except for provisions related to the
     nonamortization and amortization of goodwill and intangible
     assets acquired after June 30, 2001, which were subject
     immediately to the provisions of SFAS No. 142.  The Company
     adopted SFAS No. 142 on January 1, 2002.  SFAS No. 142
     requires a transitional goodwill impairment test at each
     reporting unit within six months of the date of adoption of
     SFAS No. 142.  However, the amounts used in the transitional
     goodwill impairment testing shall be measured as of January 1,
     2002.  The Company completed its transitional goodwill impairment
     testing and determined that no impairment exists as of January 1,
     2002.  Therefore, no impairment loss has been recorded for the
     three months and six months ended June 30, 2002, in connection
     with the adoption of SFAS No. 142.

          On January 1, 2002, in accordance with SFAS No. 142, the
     Company ceased amortization of its goodwill recorded in
     business combinations which occurred on or before June 30,
     2001.  The following information is presented as if SFAS No.
     142 was adopted as of January 1, 2001.  The reconciliation of
     previously reported earnings and earnings per share to the
     amounts adjusted for the exclusion of goodwill amortization net
     of the related income tax effect is as follows:

                                               Three Months Ended
                                                     June 30,

     2002, the Company's common stockholders approved an amendment
     to the Certificate of Incorporation increasing the authorized
     number of common shares from 150 million shares to 250 million
     shares with a par value of $1.00 per share.

11.  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's operations are conducted through six
     business segments.  The vast majority of the Company's
     operations are located within the United States.  The Company
     also has investments in foreign countries, which largely
     consists of an investment in a natural gas fired electric
     generating station in Brazil.  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
     engineering, design and build capability for 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 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.  Energy-
     related marketing and management services as well as cable and
     pipeline locating services also are provided.  The pipeline and
     energy services segment includes investments in domestic and
     international growth opportunities.  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 other
     related construction materials, including ready-mixed concrete,
     cement and asphalt, as well as value-added products and
     services in the north central and western United States,
     including Alaska and Hawaii.

          In 2001, the Company sold its coal operations to
     Westmoreland Coal Company for $28.2 million in cash, including
     final settlement cost adjustments.  The sale of the coal
     operations was effective April 30, 2001.  Included in the sale
     were active coal mines in North Dakota and Montana, coal sales
     agreements, reserves and mining equipment, and certain
     development rights at the former Gascoyne Mine site in North
     Dakota.  The Company retains ownership of coal reserves and
     leases at its former Gascoyne Mine site.  The Company recorded
     a gain of $11.0 million ($6.6 million after tax) included in
     other income - net on the Company's Consolidated Statements of
     Income from the sale in the second quarter of 2001.

          Segment information follows the same accounting policies
     as described in Note 1 of the Company's 2001 Annual Report.
     Segment information included in the accompanying Consolidated
     Statements of Income is as follows:

          On April 1, 2000, Fidelity Exploration & Production
     Company (Fidelity), an indirect wholly owned subsidiary of the
     Company, purchased substantially all of the assets of Preston
     Reynolds & Co., Inc. (Preston), a coalbed natural gas
     development operation based in Colorado with related oil and
     gas leases and properties in Montana and Wyoming.  Pursuant to
     the asset purchase and sale agreement, Preston could, but was
     not obligated to purchase, acquire and own an undivided 25
     percent working interest (Seller's Option Interest) in certain
     oil and gas leases or properties acquired and/or generated by
     Fidelity.  Fidelity had the right, but not the obligation, to
     purchase Seller's Option Interest for an amount as specified in
     the agreement.  On July 10, 2002, Fidelity purchased the
     Seller's Option Interest.

12.  Acquisitions

          During the first six months of 2002, the Company acquired
     construction materials and mining businesses in Minnesota and
     Montana, an energy development company in Montana and a utility
     services company in California, none of which was individually
     material.  The total purchase consideration for these
     businesses, consisting of the Company's common stock and cash,
     was $56.8 million.

          The above 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 or results of
     operations.

13.  Regulatory matters and revenues subject to refund

          On June 10, 2002, Montana-Dakota filed with the Wyoming
     Public Service Commission (WYPSC) for a natural gas rate
     increase.  The Company is requesting a total of $662,000
     annually or 5.6 percent above current rates.

          On May 20, 2002, Montana-Dakota filed with the Montana
     Public Service Commission (MTPSC) for a natural gas rate
     increase.  The Company is requesting a total of $3.6 million
     annually or 6.5 percent above current rates.

          On April 12, 2002, Montana-Dakota filed with the North
     Dakota Public Service Commission (NDPSC) for a natural gas rate
     increase.  The Company is requesting a total of $2.8 million
     annually or 4.1 percent above current rates.

          The NDPSC authorized its Staff to initiate an
     investigation into the earnings levels of Montana-Dakota's
     North Dakota electric operations based on Montana-Dakota's 2000
     Annual Report to the NDPSC.  The investigation was based on a
     complaint filed with the NDPSC on September 7, 2001, by the
     NDPSC Staff.  On April 24, 2002, the NDPSC issued an Order
     requiring Montana-Dakota to reduce its North Dakota electric
     rates by $4.3 million annually, effective May 8, 2002.  On
     April 25, 2002, Montana-Dakota filed an appeal of the NDPSC
     Order in the North Dakota South Central Judicial District Court
     (District Court).  The filing also requested a stay of the
     effectiveness of the NDPSC Order while the appeal is pending.
     Montana-Dakota is challenging the NDPSC's determination of the
     level of electricity sales to other utilities expected to be
     received by Montana-Dakota.  On May 2, 2002, the District Court
     granted Montana-Dakota's request for a stay of a portion of the
     $4.3 million annual rate reduction ordered by the NDPSC.
     Accordingly, Montana-Dakota implemented an annual rate
     reduction of $800,000 effective with service rendered on and
     after May 8, 2002, rather than the $4.3 million annual
     reduction ordered by the NDPSC.  The remaining $3.5 million is
     subject to refund if Montana-Dakota does not prevail in this
     proceeding.

          Reserves have been provided for the revenues that have
     been collected subject to refund with respect to Montana-
     Dakota's pending electric rate reduction.

          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 issued an initial decision on
     Williston Basin's natural gas rate change application, which
     matter is currently pending before and subject to revision by
     the FERC.

          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.

14.  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 nonrecurring 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 March 1997, 11 natural gas producers filed suit in
     North Dakota Southwest Judicial District Court (North Dakota
     District Court) against Williston Basin and the Company.  The
     natural gas producers had processing agreements with Koch
     Hydrocarbon Company (Koch).  Williston Basin and the Company
     had natural gas purchase contracts with Koch.  The natural gas
     producers alleged they were entitled to damages for the breach
     of Williston Basin's and the Company's contracts with Koch
     although no specific damages were stated.  A similar suit was
     filed by Apache Corporation (Apache) and Snyder Oil Corporation
     (Snyder) in North Dakota Northwest Judicial District Court in
     December 1993.  The North Dakota Supreme Court in December 1999
     affirmed the North Dakota Northwest Judicial District Court
     decision dismissing Apache's and Snyder's claims against
     Williston Basin and the Company.  Based in part upon the
     decision of the North Dakota Supreme Court affirming the
     dismissal of the claims brought by Apache and Snyder, Williston
     Basin and the Company filed motions for summary judgment to
     dismiss the claims of the 11 natural gas producers.  The
     motions for summary judgment were granted by the North Dakota
     District Court in July 2000.  In March 2001, the North Dakota
     District Court entered a final judgment on the July 2000 order
     granting the motions for summary judgment.  In May 2001, the 11
     natural gas producers appealed the North Dakota District
     Court's decision by filing a Notice of Appeal with the North
     Dakota Supreme Court.  Oral argument was held before the North
     Dakota Supreme Court in December 2001.  On April 16, 2002, the
     North Dakota Supreme Court affirmed the summary judgment
     entered by the North Dakota District Court.  On April 30, 2002,
     the 11 natural gas producers filed a petition for rehearing by
     the North Dakota Supreme Court.  On May 17, 2002, the North
     Dakota Supreme Court denied the 11 natural gas producers
     petition for rehearing.

          Williston Basin and the Company believe the claims of the
     11 natural gas producers are without merit and intend to
     continue vigorously contesting this suit.  Williston Basin and
     the Company believe it is not probable that the 11 natural gas
     producers will ultimately succeed given the current status of
     the litigation.

          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 pending.

          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.  In response to a motion filed by the
     defendants in this suit, the Judicial Panel on Multidistrict
     Litigation transferred the suit to the Federal District Court
     for inclusion in the pretrial proceedings of the Grynberg suit.
     Upon motion of plaintiffs, the case has been remanded to State
     District Court.  In September 2001, the defendants in this suit
     filed a motion to dismiss with the State District Court.  The
     matter is currently pending.

          Williston Basin and Montana-Dakota believe the claims of
     Grynberg and Quinque are without merit and intend to vigorously
     contest these suits.  Williston Basin and Montana-Dakota
     believe it is not probable that Grynberg and Quinque will
     ultimately succeed given the current status of the litigation.

15.  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, now owned by MBI, 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.  Based upon a review of
     the Portland Harbor sediment contamination evaluation by the
     Oregon State Department of Environmental Quality and other
     information available, MBI does not believe it is a Responsible
     Party.  In addition, MBI intends to seek indemnity for any and
     all liabilities incurred in relation to the above matters from
     Georgia-Pacific West, Inc., the seller of the commercial
     property site to MBI, 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.

________________________________

Three Months Ended June 30, 2002 and 2001

     Consolidated earnings for the quarter ended June 30, 2002,
decreased $18.5 million from the comparable period a year ago
due to lower earnings at the natural gas and oil production,
construction materials and mining, utility services, pipeline
and energy services, and electric businesses.  A lower seasonal
loss at the natural gas distribution business slightly offset
the earnings decline.

Six Months Ended June 30, 2002 and 2001

     Consolidated earnings for the six months ended June 30, 2002,
decreased $27.5 million from the comparable period a year ago due to
lower earnings at the natural gas and oil production, construction
materials and mining, utility services, electric, and pipeline and
energy services businesses.  Increased earnings at the natural gas
distribution business slightly offset the earnings decline.

will not agree with the Consolidated Statements of Income due to the
elimination of intercompany transactions between the pipeline and
energy services segment and the natural gas distribution, utility
services, construction materials and mining, and natural gas and oil
production segments.  The amounts relating to the elimination of
intercompany transactions for operating revenues, purchased natural
gas sold, and operation and maintenance expenses are as follows:

ended June 30, 2002; $22.3 million, $21.4 million and $.9 million
for the three months ended June 30, 2001; $61.7 million, $54.4
million and $7.3 million for the six months ended June 30, 2002; and
$66.1 million, $64.3 million and $1.8 million for the six months
ended June 30, 2001, respectively.

Three Months Ended June 30, 2002 and 2001

Electric

     Electric earnings decreased as a result of significantly lower
average realized sales for resale prices, combined with higher
operation and maintenance expense, primarily increased subcontractor
costs. Partially offsetting the earnings decline were decreased fuel
and purchased power costs, largely lower demand charges resulting
from the absence of a 2001 extended maintenance outage at an
electric supplier's generating station.

Natural Gas Distribution

     Normal seasonal losses at the natural gas distribution business
decreased as a result of higher retail sales volumes, largely the
result of weather that was 31 percent colder than last year.  The
pass-through of lower natural gas prices resulted in the decrease in
sales revenues and purchased natural gas sold.

Utility Services

     Utility services earnings decreased as a result of lower line
construction margins in the Rocky Mountain region related primarily
to decreased fiber optic construction work, lower construction
margins in the Central region due to an unfavorable settlement of a
billing dispute of $724,000 (after tax) and a more competitive
bidding environment for inside electrical work, the write-off of
receivables of $1.4 million (after tax) associated with a company in
the telecommunications industry, and decreased equipment sales.
Earnings from businesses acquired since the comparable period last
year partially offset these decreases.  The increase in revenues and
the related increase in operation and maintenance expense resulted
largely from businesses acquired since the comparable period last
year.

Pipeline and Energy Services

     Earnings at the pipeline and energy services business decreased
as a result of ongoing development costs of $1.8 million, largely in
connection with domestic and international energy projects. This
decrease was due, in part, to  delays in commercial production of
power from the natural gas fired electric generation project in
Brazil due to delays in the third party delivery of the natural gas
supply.  Higher operation and maintenance expenses related to
expansion of the gathering system to accommodate increasing natural
gas volumes, and lower technology services revenues at one of the
Company's energy services operations, largely due to the depressed
telecommunications market also decreased earnings.  Partially
offsetting the earnings decline were higher gathering volumes at
higher average rates and higher volumes transported into storage.
The absence in 2002 of a 2001 write-off of an investment in a
software development company of $699,000 (after tax) also partially
offset the earnings decline.  The decrease in energy services
revenue and the related decrease in purchased natural gas sold were
due primarily to decreased energy marketing volumes resulting from
the sale of the vast majority of the Company's low-margin energy
marketing operations in the third quarter of 2001.

Natural Gas and Oil Production

     Natural gas and oil production earnings decreased largely due to
lower realized natural gas and oil prices which were 29 percent and
13 percent lower than last year, respectively, partially offset by
higher natural gas production of 9 percent, largely from operated
production in the Rocky Mountain area.  Also adding to the earnings
decline were increased operation and maintenance expense, mainly
higher lease operating expenses, and increased depreciation,
depletion and amortization expense, both relating to higher
production volumes.  Hedging activities for natural gas for the
second quarter of 2002 and 2001 resulted in realized prices that
were 105 percent and unchanged, respectively, of what otherwise
would have been received. In addition, hedging activities for oil
for the second quarter of 2002 and 2001 resulted in realized prices
that were 99 and 102 percent, respectively, of what otherwise would
have been received.

Construction Materials and Mining

     Earnings for the construction materials and mining business
decreased as a result of the one-time gain in 2001 from the sale of
the Company's coal operations of $11.0 million ($6.6 million after
tax), included in other income - net, as previously discussed in
Note 11 of Notes to Consolidated Financial Statements.  Earnings
decreased as a result of a late construction season start in Montana
due to cold and wet spring weather and the absence of earnings from
the Company's coal operations that were sold effective April 30,
2001.  These decreases were offset by the net earnings at the other
existing construction materials and mining locations as well as
earnings from companies acquired since the comparable period last
year.

Six Months Ended June 30, 2002 and 2001

Electric

     Electric earnings decreased as a result of significantly lower
average realized sales for resale prices due to weaker demand in the
sales for resale markets, combined with the absence in 2002 of 2001
insurance recovery proceeds related to a 2000 outage at an electric
generating station. Partially offsetting the earnings decline were
decreased fuel and purchased power costs due in part to lower demand
charges resulting from the absence of a 2001 extended maintenance
outage at an electric supplier's generating station, and decreased
operation and maintenance expense, largely lower payroll costs.

Natural Gas Distribution

     Earnings at the natural gas distribution business increased as a
result of higher retail sales volumes, largely the result of weather
that was 5 percent colder than last year, increased return on
natural gas storage, demand and prepaid commodity balances,
decreased operation and maintenance expense due primarily to
decreased bad debt expense and lower payroll costs, and higher
service and repair margins.  The pass-through of lower natural gas
prices resulted in the decrease in sales revenues and purchased
natural gas sold.

Utility Services

     Utility services earnings decreased as a result of lower line
construction margins in the Rocky Mountain region, lower
construction margins in the Central region, the write-off of a
receivable, and decreased equipment sales, all as previously
discussed.  Partially offsetting the decline in earnings were
decreased interest expense due to lower average borrowings and
earnings from businesses acquired since the comparable period last
year.  The increase in revenues and the related increase in
operation and maintenance expense resulted largely from businesses
acquired since the comparable period last year.

Pipeline and Energy Services

     Earnings at the pipeline and energy services business decreased
as a result of ongoing development costs of $1.9 million, largely in
connection with domestic and international energy projects. This
decrease was due, in part, to  delays in commercial production of
power from the natural gas fired electric generation project in
Brazil due to delays in the third party delivery of the natural gas
supply. Higher operation and maintenance expense largely related to
the expansion of the gathering system to accommodate increasing
natural gas volumes, lower technology services revenues at one of
the Company's energy services operations, as previously discussed,
and higher depreciation, depletion and amortization expense
resulting from increased property, plant and equipment balances also
decreased earnings.  Partially offsetting the earnings decline were
higher gathering volumes at higher average rates, higher volumes
transported into storage, and increased storage revenues.  The
absence in 2002 of a 2001 write-off of an investment in a software
development company, as previously discussed, also partially offset
the earnings decline. The decrease in energy services revenue and
the related decrease in purchased natural gas sold were due
primarily to decreased energy marketing volumes resulting from the
sale of the vast majority of the Company's low-margin energy
marketing operations in the third quarter of 2001.

Natural Gas and Oil Production

     Natural gas and oil production earnings decreased largely due to
lower realized natural gas and oil prices which were 47 percent and
20 percent lower than last year, respectively, partially offset by
higher natural gas production of 13 percent, largely from operated
production in the Rocky Mountain area.  Also adding to the earnings
decline were increased operation and maintenance expense, mainly
higher lease operating expenses, lower sales volumes of inventoried
natural gas, and increased depreciation, depletion and amortization
expense due to higher production volumes and higher rates.
Partially offsetting the earnings decline were the effects of the
nonrecurring compromise agreement of $27.4 million ($16.6 million
after-tax), included in operating revenue, as discussed in Note 14
of Notes to Consolidated Financial Statements.  Hedging activities
for natural gas for the six months ended June 30, 2002 and 2001
resulted in realized prices that were 104 and 96 percent,
respectively, of what otherwise would have been received.  In
addition, hedging activities for oil for the six months ended
June 30, 2002 and 2001 resulted in realized prices that were 102
percent, of what otherwise would have been received.

Construction Materials and Mining

     Earnings for the construction materials and mining business
decreased due to the previously mentioned 2001 one-time gain from
the sale of the Company's coal operations.  Decreased construction
activity, the result of a late construction season start in Montana
due to cold and wet spring weather, and lower ready-mixed concrete
volumes at existing operations, higher depreciation, depletion and
amortization expense due to higher property, plant and equipment
balances, and increased selling, general and administrative costs
added to the earnings decrease.  The absence of earnings from the
Company's coal operations that were sold in April 2001, also added
to the earnings decrease.  Increased aggregate and asphalt margins
partially offset the earnings decrease.

Prospective Information

     The following information includes highlights of the key growth
strategies, projections and certain assumptions for the Company over
the next few years and other matters for each of its six business
segments.  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 Safe Harbor for Forward-
looking Statements.  Changes in such assumptions and factors could
cause actual future results to differ materially from the Company's
targeted growth, revenue and earnings projections.  Given the
current business environment, the Company is reviewing its long-term
growth goals.

MDU Resources Group, Inc.

- - Earnings per share, diluted, for 2002 are projected in the
  $1.80 to $2.00 range.  Excluding the benefit of the compromise
  agreement discussed in Note 14 of Notes to Consolidated Financial
  Statements, earnings per share from operations are projected to be
  in the approximate range of $1.60 to $1.80.

- - Weighted average diluted common shares outstanding for the
  twelve months ended December 31, 2001, were 67.9 million.  The
  Company anticipates a 3 percent to 7 percent increase in weighted
  average diluted shares outstanding by 2002 year end.

- - The Company expects the percentage of 2002 earnings per share
  from operations, excluding the benefit of the compromise agreement,
  by quarter to be in the following approximate ranges:

  -  Third Quarter - 40 percent to 45 percent
  -  Fourth Quarter - 29 percent to 34 percent

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

- - The Company estimates that the benefit resulting solely from
  the discontinuance of goodwill amortization would be 5 to 6 cents
  per common share in 2002.

Electric

- - Montana-Dakota has obtained and holds valid and existing
  franchises authorizing it to conduct its electric and natural gas
  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.

- - On May 2, 2002, the District Court granted Montana-Dakota's
  request for a stay of a portion of the $4.3 million annual rate
  reduction ordered by the NDPSC.  Accordingly, Montana-Dakota
  implemented an annual rate reduction of $800,000 effective with
  service rendered on and after May 8, 2002, rather than the $4.3
  million annual reduction ordered by the NDPSC.  The remaining $3.5
  million is subject to refund if Montana-Dakota does not prevail in
  this proceeding.  Reserves have been provided for the revenues that
  have been collected subject to refund with respect to this pending
  electric rate reduction.  For more information on this proceeding
  see Note 13 of Notes to Consolidated Financial Statements.

- - Due to growing electric demand, a 40-megawatt natural gas
  turbine power plant may be added in the two to five year planning
  horizon.

- - Currently, the Company is working with the State of North
  Dakota to determine the feasibility of constructing a 500-megawatt
  lignite-fired power plant in western North Dakota.  The first
  preliminary decision is expected in December 2002.

Natural gas distribution

- - Annual natural gas throughput for 2002 is expected to be
  approximately 56 million decatherms, with about 40 million
  decatherms from sales and 16 million decatherms from transportation.

- - On June 10, 2002, Montana-Dakota filed with the WYPSC for a
  natural gas rate increase.  The Company is requesting a total of
  $662,000 annually or 5.6 percent above current rates.

- - On May 20, 2002, Montana-Dakota filed with the MTPSC for a
  natural gas rate increase.  The Company is requesting a total of
  $3.6 million annually or 6.5 percent above current rates.

- - On April 12, 2002, Montana-Dakota filed with the NDPSC for a
  natural gas rate increase.  The Company is requesting a total of
  $2.8 million annually or 4.1 percent above current rates.

Utility services

- - Revenues for this segment are expected to approximate $500
  million in 2002.

- - Earnings for 2002, compared to 2001, are expected to increase
  by approximately 10 percent.

Pipeline and energy services

- - In 2002, natural gas throughput from this segment, including
  both transportation and gathering, is expected to increase by
  approximately 5 percent over the 2001 record level throughput.

- - A 247-mile pipeline to transport additional natural gas to
  market and enhance the use of the Company's storage facilities is
  currently under regulatory review.  Depending upon the timing of the
  receipt of the necessary regulatory approval, construction
  completion could occur as early as late 2003.

- - The Company continues to pursue electric generation
  opportunities in Brazil.  These projects are targeted toward a niche
  market where we will provide energy on a contractual basis in order
  to reduce risk.  The first 100 megawatts have begun commercial
  production and the second 100 megawatts are scheduled to begin
  commercial production early in 2003.

- - 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; however, the
  Company believes there are other markets for the energy and is
  studying its options regarding this project.  Pending completion
  of this study, the Company has deferred construction activities
  and is investigating suspension of construction activities.  At
  June 30, 2002, the Company's investment in this project was
  approximately $16.5 million.

Natural gas and oil production

- - Due to delays caused by weather, regulatory hurdles and
  environmental objections to discharge of water, the Company now
  anticipates combined natural gas and oil production at this segment
  in 2002 to be approximately 10 percent to 15 percent higher than in
  2001.  To help mitigate the water issues, the Company is
  implementing new water management practices and policies.

- - Due to the aforementioned reasons, this segment now expects to
  drill approximately 250 wells in 2002.

- - Natural gas prices in the Rocky Mountain Region for July
  through December 2002 reflected in the Company's 2002 earnings
  guidance are in the range of $2.00 to $2.50 per Mcf.  The Company's
  estimates for natural gas prices on the NYMEX for July through
  December 2002 reflected in the Company's 2002 earnings guidance are
  in the range of $3.25 to $3.75 per Mcf.  During 2001, more than half
  of this segment's natural gas production was priced using Rocky
  Mountain or other non-NYMEX prices.

- - NYMEX crude oil prices for July through December 2002 reflected
  in the Company's 2002 earnings guidance are in the range of $24 to
  $27 per barrel.

- - This segment has hedged a portion of its 2002 production.  The
  Company has entered into swap agreements and fixed price forward
  sales representing approximately 35 percent to 40 percent of 2002
  estimated annual natural gas production.  These natural gas swaps
  are at various indices and range from a low CIG index of $2.73 to a
  high NYMEX price of $4.34.  The Company has also entered into oil
  swap agreements at average NYMEX prices in the range of $24.80 to
  $25.90 per barrel, representing approximately 30 percent to 35
  percent of the Company's 2002 estimated annual oil production.

- - In addition to these 2002 hedges, the Company has hedged a
  portion of its 2003 production.  The Company has entered into
  costless collars and fixed price forward sales, representing
  approximately 5 percent to 10 percent of 2003 estimated annual
  natural gas production.  The costless collars range from
  approximately $3.15 to $4.25 per Mcf.

Construction materials and mining

- - Excluding the effects of potential future acquisitions,
  aggregate volumes are expected to increase by approximately 18
  percent to 23 percent in 2002 and asphalt and ready-mixed concrete
  volumes are expected to increase by 15 percent to 20 percent and 5
  percent to 10 percent, respectively in 2002.

- - Revenues for this segment are expected to exceed $900 million
  in 2002.

New Accounting Standards

     In June 2001, the FASB approved Statement of Financial
Accounting Standards No. 143, "Accounting for Asset Retirement
Obligations."  For further information on SFAS No. 143, see Note 6
of Notes to Consolidated Financial Statements.

     In June 2001, the FASB approved Statement of Financial
Accounting Standards No. 142, "Goodwill and Other Intangible
Assets."  Under SFAS No. 142, goodwill and other intangible assets
with indefinite lives are no longer amortized but are reviewed
annually, or more frequently if impairment issues arise, for
impairment.  As of December 31, 2001, the Company had unamortized
goodwill of $174.0 million that was subject to the provisions of
SFAS No. 142.  Had SFAS No. 142 been in effect for 2001, earnings
would have been $4.2 million higher.

     In August 2001, the FASB approved Statement of Financial
Accounting Standards No. 144, "Accounting for the Impairment or
Disposal of Long-Lived Assets."  The adoption of SFAS No. 144 was
effective for the Company beginning on January 1, 2002.  The
adoption of SFAS No. 144 did not have a material affect on the
Company's financial position or results of operations.

     In April 2002, the FASB approved Statement of Financial
Accounting Standards No. 145, "Rescission of FASB Statements No. 4,
44 and 64, Amendment of FASB Statement No. 13, and Technical
Corrections."  For further information on SFAS No. 145, see Note 6
of Notes to Consolidated Financial Statements.

     In June 2002, the EITF adopted the position in EITF No. 02-3,
"Recognition and Reporting of Gains and Losses on Energy Trading
Contracts under EITF Issues No. 98-10, 'Accounting for Contracts
Involved in Energy Trading and Risk Management Activities,' and
No. 00-17, 'Measuring the Fair Value of Energy-Related Contracts in
Applying Issue No. 98-10.'"  For further information on EITF
No. 02-3, see Note 6 of Notes to Consolidated Financial Statements.

     In June 2002, the FASB approved SFAS No. 146, "Accounting for
Costs Associated with Exit or Disposal Activities."  For further
information on SFAS No. 146, see Note 6 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 production properties, revenue recognition, derivatives,
purchase accounting and accounting for the effects of regulation.
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, 2001.  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, 2001.

Liquidity and Capital Commitments

Cash flows

Operating activities --

     Cash flows from operating activities in the first six months of
2002 decreased $61.5 million from the comparable 2001 period,
primarily due to a decrease in net income of $27.5 million and the
decrease in cash from changes in working capital items of $48.8
million.  This decrease was primarily due to lower natural gas
prices in the first six months of 2002 compared to the same period
of 2001.  Higher depreciation, depletion and amortization expense of
$7.4 million resulting largely from increased property, plant and
equipment balances partially offset the decrease in cash flows from
operating activities.

Investing activities --

     Cash flows used in investing activities in the first six months
of 2002 decreased $22.4 million compared to the comparable period in
2001, the result of a decrease in net capital expenditures,
including acquisitions and net proceeds from the sale or disposition
of property.  Net capital expenditures exclude the following noncash
transactions related to acquisitions: issuance of the Company's
equity securities of $41.8 million and $57.3 million in the first
six months of 2002 and 2001, respectively.

Financing activities --

     Financing activities resulted in an increase in cash flows for
the first six months of 2002 of $51.3 million compared to the
comparable 2001 period.  This increase was largely due to the
decrease in the repayment of long-term debt of $52.6 million and the
increase in issuance of long-term debt of $16.1 million.  This
increase was partially offset by a decrease in proceeds from
issuance of common stock of $26.8 million.

Capital expenditures

     Net capital expenditures for the year 2002 are estimated at
approximately $390 million, including those for acquisitions, system
upgrades, routine replacements, service extensions, routine
equipment maintenance and replacements, land and building
improvements, pipeline and gathering expansion projects, the further
enhancement of natural gas and oil production and reserve growth,
power generation opportunities and for potential future acquisitions
and other growth opportunities.  Approximately 30 percent to 35
percent of estimated net capital expenditures for 2002 are for
completed and potential future 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 2002
capital expenditures referred to above.  It is anticipated that all
of the funds required for capital expenditures will be met from
various sources.  These sources include internally generated funds,
a revolving credit and term loan agreement, a commercial paper
credit facility at Centennial, as described below, and through the
issuance of long-term debt and the Company's equity securities.

     The estimated 2002 capital expenditures referred to above
include completed 2002 acquisitions including construction materials
and mining businesses in Minnesota and Montana; a utility services
company in California; and an energy development company in Montana.
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

     The Company has a revolving credit and term loan agreement with
various banks that allows for borrowings of up to $40 million.
Under this agreement, $5 million was outstanding at June 30, 2002.
The borrowings under this agreement, which allows for subsequent
borrowings up to a term of one year, are classified as long term as
the Company intends to refinance these borrowings on a long-term
basis.  The Company intends to renew this agreement, which expires
on December 31, 2002.

     Centennial has a revolving credit agreement (Centennial credit
agreement) with various banks that supports Centennial's $350
million commercial paper program (Centennial commercial paper
program).  There were no outstanding borrowings under the Centennial
credit agreement at June 30, 2002.  Under the Centennial commercial
paper program, $297.9 million was outstanding at June 30, 2002.  The
Centennial commercial paper borrowings are classified as long term
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 27, 2002, on an annual basis.

     Centennial has an uncommitted long-term master shelf agreement
that allows for borrowings of up to $300 million.  Under the terms
of the master shelf agreement, $242.2 million was outstanding at
June 30, 2002.  On August 2, 2002, Centennial borrowed an additional
$50 million under the terms of this agreement.  The $50 million in
proceeds were used to pay down Centennial commercial paper program
borrowings.  Centennial currently plans to expand its borrowing
capacity under this facility.

     MDU International has a credit agreement that allows for
borrowings of up to $25 million.  Under this agreement, $4.5 million
was outstanding at June 30, 2002.  The Company intends to renew this
credit agreement, which expires June 30, 2003, on an annual basis.

     The Company also has unsecured short-term lines of credit from
a number of banks totaling $60 million that allow the Company to
borrow under the lines and/or provide credit support for a
commercial paper program.  There were no outstanding borrowings
under these lines of credit or this commercial paper program at
June 30, 2002.  The Company intends to renew these lines of credit
on an annual basis.

     The Company's goal is to maintain acceptable credit ratings
under its credit agreements and individual bank lines of credit 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 rating, the Company 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 the Company does not currently anticipate, it
may need to borrow under its committed bank lines.

     To the extent the Company needs to borrow under its committed
bank lines, it would be expected to incur increased annualized
interest expense on its variable rate debt by approximately $447,000
(after-tax) for the calendar year 2002 based on June 30, 2002
variable rate borrowings.  Based on the Company's overall interest
rate exposure at June 30, 2002, this change would not have a
material affect on the Company's results of operations.

     On an annual basis, the Company negotiates the placement of the
Centennial credit agreement and its individual bank lines of credit
that provide credit support to access the capital markets.  In the
event the Company were unable to successfully negotiate the bank
credit facilities, or in the event the fees on such facilities
became too expensive, which the Company 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 or its subsidiaries'
credit facilities, the Company and 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,
limitations on priority debt, limitations on sale of assets and
limitations on loans and investments in addition to certain
restrictions imposed under the terms and conditions of the Company's
Indenture of Mortgage as discussed below.  The Company and its
subsidiaries are in compliance with these covenants and met the
required conditions at June 30, 2002.  In the event the Company or
its subsidiaries do not comply with the applicable covenants and
other conditions, alternative sources of funding may need to be
pursued as previously described.

     The Centennial credit agreement and the Centennial uncommitted
long-term master shelf agreement 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 which causes such indebtedness to be due
prior to its stated maturity or the contingent obligation to become
payable, the Centennial credit agreement and the Centennial
uncommitted long-term master shelf agreement will be in default.
The Centennial credit agreement, the Centennial uncommitted long-
term master shelf agreement and Company practice limit the amount of
subsidiary indebtedness.

     Currently, there are no credit facilities that contain cross-
default provisions between Centennial and the Company.

     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, 2002, the Company could have issued approximately
$312 million of additional first mortgage bonds.

     The Company's coverage of fixed charges including preferred
dividends was 4.5 times and 5.3 times for the twelve months ended
June 30, 2002 and December 31, 2001, respectively.  Additionally,
the Company's first mortgage bond interest coverage was 8.0 times
and 8.5 times for the twelve months ended June 30, 2002 and
December 31, 2001, respectively.  Common stockholders' equity as a
percent of total capitalization was 58 percent at June 30, 2002 and
December 31, 2001.

Contractual obligations and commercial commitments

     There are no material changes in the Company's contractual
obligations on long-term debt, operating leases and purchase
commitments from those reported in the Company's Annual Report on
Form 10-K for the year ended December 31, 2001.  For more
information on contractual obligations and commercial commitments,
see Item 7 in the Company's Annual Report on Form 10-K for the year
ended December 31, 2001.

     Certain subsidiaries of the Company have financial guarantees
outstanding at June 30, 2002.  These guarantees as of June 30, 2002,
are approximately $27.9 million, of which approximately $24.5
million pertain to Centennial's guarantee of certain obligations in
connection with the natural gas fired electric generation station in
Brazil, as discussed in Notes 10 and 15 of Notes to Consolidated
Financial Statements in the 2001 Annual Report and Items 2 and 3 of
this 10-Q.  As of June 30, 2002, with respect to these guarantees,
there were approximately $23.5 million outstanding through 2003,
$1.4 million outstanding through 2004 and $3.0 million outstanding
thereafter.


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 --

     The Company utilizes derivative instruments, including natural
gas and oil price swap and natural gas collar agreements, to manage
a portion of the market risk associated with fluctuations in the
price of natural gas and oil on the Company'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, 2001, and Notes to
Consolidated Financial Statements in this Form 10-Q.

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, 2001.  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,
2001.

Foreign currency risk --

     The Company has a 49 percent equity investment in a 200
megawatt natural gas fired electric generation project (Project) in
Brazil which has a portion of its borrowings and payables
denominated in U.S. Dollars.  The Company 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 of the Project during its construction phase was deemed to
be the U.S. Dollar.  Upon commencement of operations of the first
100 megawatts of the Project on July 7, 2002, the functional
currency of the Project became the Brazilian Real.  Adjustments
attributable to the translation of nonmonetary assets between the
U.S. Dollar and the Brazilian Real as of July 7, 2002, will be
recorded in accumulated other comprehensive income in the third
quarter of 2002.

     Subsequent to July 7, 2002, the effect of changes in currency
exchange rates with respect to the Project's third party U.S. Dollar
denominated borrowings and payables will be reflected in net income.
At June 30, 2002, the Project had third party U.S. Dollar denominated
borrowings and payables of approximately $59.3 million.  If, for
example, the value of the Brazilian Real decreased in relation to
the U.S. Dollar by 10 percent, the Company, with respect to its
interest in the Project, would record a foreign currency translation
loss in net income of approximately $2.7 million (after tax) based
on the third party U.S. Dollar denominated borrowings and payables
at June 30, 2002.

     The Project also has U.S. Dollar denominated borrowings payable
to a subsidiary of the Company of $23.8 million.  Foreign currency
translation adjustments on the Project's borrowings payable to the
Company would be recorded in accumulated other comprehensive income.

     The Company's equity income from this Brazilian investment is
also impacted by fluctuations in currency exchange rates.  In
addition to the Company's investment in this Project, which
consisted of the borrowings payable to a subsidiary of the Company
as noted above, Centennial has guaranteed project obligations and
loans of approximately $24.5 million as of June 30, 2002.

     The Company is managing a portion of its foreign currency
exchange risk through contractual provisions contained in the
Project's power purchase agreement with Petrobras that provides for
annual partial price adjustments based on changes in the U.S.
Dollar/Brazilian Real exchange rate.  On August 12, 2002, the
Company entered into a foreign currency collar agreement for a
notional amount of $21.3 million with a fixed price floor of R$3.10
and a fixed price ceiling of R$3.40 to manage a portion of its
foreign currency risk.  The term of the collar agreement is from
August 12, 2002 through February 3, 2003, and the collar agreement
settles on February 3, 2003.  Gains or losses on this derivative
instrument will be recorded in earnings each period.


                    PART II -- OTHER INFORMATION
