     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 may not be indicative of results for the
     full fiscal year.

 3.  Cash flow information

         Cash expenditures for interest and income taxes were as
     follows:

4.   New accounting pronouncement

         The company adopted Statement of Financial Accounting
     Standards No. 133, "Accounting for Derivative Instruments and
     Hedging Activities" (SFAS No. 133), amended by Statement of
     Financial Accounting Standards No. 137, "Accounting for
     Derivative Instruments and Hedging Activities - Deferral of the
     Effective Date of FASB Statement No. 133" and Statement of
     Financial Accounting Standards No. 138, "Accounting for Certain
     Derivative Instruments and Certain Hedging Activities" (all
     such statements hereinafter referred to as SFAS No. 133) on
     January 1, 2001.  SFAS No. 133 establishes accounting and
     reporting standards requiring that every derivative instrument
     (including certain derivative instruments embedded in other
     contracts) be recorded on the balance sheet as either an asset
     or liability measured at its fair value.  SFAS No. 133 requires
     that changes in the derivative instrument's fair value be
     recognized currently in earnings unless specific hedge
     accounting criteria are met.  Special accounting for qualifying
     hedges allows derivative gains and losses to offset the related
     results on the hedged item in the income statement, and
     requires that a company must formally document, designate and
     assess the effectiveness of transactions that receive hedge
     accounting treatment.

         SFAS No. 133 requires that as of the date of initial
     adoption, the difference between the fair market value of
     derivative instruments recorded on the balance sheet and the
     previous carrying amount of those derivative instruments be
     reported in net income or other comprehensive income (loss), as
     appropriate, as the cumulative effect of a change in accounting
     principle in accordance with APB 20, "Accounting Changes."  The
     company reported a net-of-tax cumulative-effect adjustment of
     $6.1 million in accumulated other comprehensive loss to
     recognize at fair value all derivative instruments that are
     designated as cash-flow hedging instruments, which the company
     expects to reflect in earnings, subject to changes in natural
     gas and oil market prices, over the twelve months ending
     December 31, 2001.  The transition to SFAS No. 133 did not have
     an effect on the company's net income at adoption.

5.   Derivative instruments

         As of March 31, 2001, the company held derivative
     instruments designated as cash flow hedging instruments and
     other derivative instruments in relation to its energy
     marketing operations which have not been designated as hedges.
     All derivative instruments are recognized on the Consolidated
     Balance Sheets at fair value.

     Hedging activities

         The cash flow hedging instruments in place at March 31,
     2001, are comprised of natural gas and oil price swap
     agreements and an interest rate swap agreement.  The objective
     for holding the natural gas and oil price swap agreements is 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 objective for holding the interest rate swap agreement is
     to manage a portion of the company's interest rate risk on the
     forecasted issuances of fixed-rate debt under the company's
     commercial paper program.  The company designated each of the
     natural gas and oil price swap agreements as a hedge of the
     forecasted sale of natural gas and oil production and
     designated the interest rate swap agreement as a hedge of the
     risk of changes in interest rates on the company's forecasted
     issuances of fixed-rate debt under the company's commercial
     paper program.

         The company's policy allows the use of derivative
     instruments as part of an overall energy price and interest
     rate risk management program to efficiently manage and minimize
     commodity price and interest rate risk.  The company's policy
     prohibits the use of derivative instruments for speculating to
     take advantage of market trends and conditions and the company
     has procedures in place to monitor compliance with its
     policies.  The company is exposed to credit-related losses in
     relation to hedged derivative instruments in the event of
     nonperformance by counterparties.  The company has policies and
     procedures, which management believes minimize credit-risk
     exposure.  These policies and procedures include an evaluation
     of potential counterparties' credit ratings, credit exposure
     limitations, settlement of natural gas and oil price swap
     agreements monthly and settlement of interest rate swap
     agreements within 90 days.  Accordingly, the company does not
     anticipate any material effect to its financial position or
     results of operations as a result of nonperformance by
     counterparties.

         Upon the adoption of SFAS No. 133, the company recorded the
     fair market value of the natural gas and oil price swap
     agreements on the company's Consolidated Balance Sheets.  On an
     ongoing basis, the company adjusts its balance sheet to reflect
     the current fair market value of the natural gas and oil price
     swap agreements and the interest rate swap agreement.  The
     related gains or losses on these agreements are recorded in
     common stockholders' equity as a component of other
     comprehensive income (loss).  At the date the underlying
     transaction occurs, the amounts accumulated in other
     comprehensive income (loss) are reported in the Consolidated
     Statements of Income.  To the extent that the hedges are not
     effective, the ineffective portion of the changes in fair
     market value is recorded directly in earnings.

         For the three months ended March 31, 2001, the company
     recognized the ineffectiveness of all cash-flow hedges, which
     is included in operating revenues and interest expense on the
     Consolidated Statements of Income for the natural gas and oil
     price swap agreements and the interest rate swap agreement,
     respectively.  For the three months ended March 31, 2001, the
     amount of ineffectiveness recognized was immaterial.  For the
     three months ended March 31, 2001, the company did not exclude
     any components of the derivative instruments' 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 March 31, 2001, the
     maximum length of time over which the company is hedging its
     exposure to the variability in future cash flows for forecasted
     transactions is nine months and the company estimates that
     losses of $1.0 million will be reclassified from accumulated
     other comprehensive loss into earnings, subject to changes in
     natural gas and oil market prices and interest rates, within
     the nine months between April 1, 2001 and December 31, 2001 as
     the hedged transactions affect earnings.

         In the event a derivative instrument does not qualify for
     hedge accounting because it is no longer highly effective in
     offsetting changes in cash flows of a hedged item; or if the
     derivative instrument expires or is sold, terminated, or
     exercised; or if management determines that designation of the
     derivative instrument as a hedge instrument is no longer
     appropriate, hedge accounting will be discontinued, and the
     derivative instrument would continue to be carried at fair
     value with changes in its fair value recognized in earnings.
     In these circumstances, the net gain or loss at the time of
     discontinuance of hedge accounting would remain in other
     comprehensive income (loss) until the period or periods during
     which the hedged forecasted transaction affects earnings, at
     which time the net gain or loss would be reclassified into
     earnings.  In the event a cash flow hedge is discontinued
     because it is unlikely that a forecasted transaction will
     occur, the derivative instrument would continue to be carried
     on the balance sheet at its fair value, and gains and losses
     that were accumulated in other comprehensive income (loss)
     would be recognized immediately in earnings.  The company's
     policy requires approval to terminate a hedge agreement prior
     to its original maturity.

     Energy marketing

         In its energy marketing operations, the company enters into
     other derivative instruments that have not been designated as
     hedges.  These derivative instruments are natural gas forward
     purchase and sale commitments.  These commitments involve the
     purchase and sale of natural gas and related delivery of such
     commodity.  The energy marketing operations seek to match
     natural gas purchases and sales on specific derivative
     instruments so that a margin is obtained on the transportation
     of such commodity as distinguished from earning a margin on
     changes in market prices.  In addition, the energy marketing
     derivative instruments are generally entered into on a seasonal
     basis with a duration generally not exceeding 12 months.  The
     net change in fair value representing unrealized gains and
     losses resulting from changes in market prices on these
     derivative instruments is reflected as operating revenues or
     purchased natural gas sold on the company's Consolidated
     Statements of Income.  Net unrealized gains and losses on these
     derivative instruments were not material for the three months
     ended March 31, 2001 and 2000.

         The company is exposed to credit risk in relation to
     derivative instruments entered into at the company's energy
     marketing operations in the event of nonperformance by
     counterparties.  The company maintains credit procedures, which
     management believes minimize credit-risk exposure.  These
     procedures include applying specific eligibility criteria to
     prospective counterparties and may require letters of credit or
     similar security to secure payment on such sales contracts.
     However, despite mitigation efforts, defaults by counterparties
     may occur.  To date, no such defaults have had a material
     effect on the company's financial position or results of
     operations.

6.   Comprehensive income

         Upon the adoption of SFAS No. 133 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
     March 31, 2001, the company has recorded unrealized gains and
     losses on natural gas and oil price swap and interest rate swap
     agreements in accordance with SFAS No. 133.  These amounts are
     reflected in the following table.  For additional information on
     the adoption of SFAS No. 133, see Notes 4 and 5 of the Notes to
     the Consolidated Financial Statements in this Form 10-Q.

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

 7.  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.  Substantially all of the company's operations are
     located within the United States.  The electric segment
     generates, transmits and distributes electricity and the
     natural gas distribution business 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 construction
     company specializing in electric, natural gas and
     telecommunication utility construction as well as interior
     industrial electrical, exterior lighting and traffic
     signalization.  Utility services has engineering, design and
     build capability and provides related specialty equipment sales
     and rental services throughout most of the United States.  The
     pipeline and energy services segment provides natural gas
     transportation, underground storage and gathering services
     through regulated and nonregulated pipeline systems and
     provides energy-related marketing and management services in
     the Rocky Mountain, Midwest, Southern and Central regions of
     the United States.  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 and markets aggregates and
     related value-added construction materials products and
     services in Alaska, California, Hawaii, Minnesota, Montana,
     Oregon, Washington and Wyoming.

         On May 11, 2001, the company announced that the sale of
     its coal operations to Westmoreland Coal Company for $28.8 million
     in cash, excluding final settlement cost adjustments, has been
     finalized.  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
     will record a gain from the sale in the second quarter of 2001.
     The company's estimate of the gain on the sale of the coal operations
     is in the range of $4 million to $8 million after tax and is subject
     to various post-closing adjustments.

         Segment information follows the same accounting policies as
     described in Note 1 of the company's 2000 Annual Report.
     Segment information included in the accompanying Consolidated
     Statements of Income is as follows:

        Accounting Standards No. 71, "Accounting for the Effects of
        Regulation" (SFAS No. 71), intercompany coal sales are not
        eliminated.

8.   Regulatory matters and revenues subject to refund

         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. On May 9, 2001, the
     Administrative Law Judge issued an Initial Decision, which is
     subject to revision by the FERC, on Williston Basin's natural
     gas rate change application.  Williston Basin is evaluating the
     implications of the Initial Decision.

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

9.   Litigation

         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.  On March 5, 2001, the North
     Dakota District Court entered a final judgment on the July 2000
     order granting the motions for summary judgment. On May 4,
     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.

         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 or 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.  Williston Basin and Montana-
     Dakota are awaiting a decision from the Federal District Court.

         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, 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 for Stevens County, Kansas.

         Williston Basin and Montana-Dakota believe the claims of
     Grynberg and Quinque are without merit and intend to vigorously
     contest these suits.

10.  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.

________________________________


Three Months Ended March 31, 2001 and 2000

     Consolidated  earnings  for the quarter  ended  March  31,  2001,
increased  $19.3 million from the comparable period a year  ago  due
to higher  earnings  at the natural gas and oil production,  utility
services,  electric,  and  natural gas  distribution  businesses,
partially  offset  by  lower  earnings  at  the  other   business
segments.

     Amounts presented in the preceding tables for operating
revenues, purchased natural gas sold and operation and maintenance
expenses 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 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:  $43.8 million, $42.9
million and $.9 million for the three months ended March 31, 2001;
and $24.6 million, $24.4 million and $.2 million for the three
months ended March 31, 2000, respectively.

Three Months Ended March 31, 2001 and 2000

Electric

     Electric earnings increased due to increased sales for resale
volumes at higher average realized rates, primarily the result of a
strong sales for resale market, and lower fuel and purchased power
costs, largely due to insurance recovery proceeds related to a 2000
outage at an electric generating station.  Higher operation and
maintenance expense, primarily increased payroll expense and higher
subcontractor costs, partially offset the earnings increase.

Natural Gas Distribution

     Earnings increased at the natural gas distribution business due
to higher retail sales volumes resulting from weather that was 12
percent colder than the comparable period last year and earnings
from a business acquired in July 2000.  This increase was largely
offset by higher operation and maintenance expense, primarily
increased payroll expense and higher bad debt expense.  Lower
service and repair margins and lower average realized rates, also
partially offset the earnings improvement. Significantly higher
natural gas prices also added to the increase in sales revenue and
purchased natural gas sold.

Utility Services

     Utility services earnings increased as a result of higher line
construction margins in the Rocky Mountain region, primarily related
to fiber-optic-cable installation projects, and earnings from
businesses acquired since the comparable period last year.

Pipeline and Energy Services

     Earnings at the pipeline and energy services business decreased
due to higher operation and maintenance expense, primarily higher
compressor-related expenses and outside services, and decreased
storage revenues.  Higher natural gas throughput at the pipeline
partially offset the earnings decline.  The increase in energy
services revenue and the related increase in purchased natural gas
sold resulted from significantly higher natural gas prices.

Natural Gas and Oil Production

     Natural gas and oil production earnings increased largely due to
an increase in natural gas and oil production of 50 percent and 5
percent since last year, respectively, combined with higher realized
natural gas and oil prices which were 159 percent and 24 percent
higher than last year, respectively.  The higher production was due
to an acquisition since the comparable period last year and ongoing
development of existing properties.  Higher margins on inventoried
natural gas also added to the earnings increase.  Partially
offsetting the earnings improvement were increased depreciation,
depletion and amortization expense, due to higher production volumes
and higher rates, and increased operation and maintenance expense,
mainly higher lease operating expenses and higher general and
administrative costs due primarily to an acquisition.  Hedging
activities for natural gas for the first three months of 2001
resulted in realized prices that were 93 percent of what otherwise
would have been received.  Hedging activities for natural gas for
the first three months of 2000 resulted in realized prices that were
unchanged.  In addition, hedging activities for oil for the first
three months of 2001 and 2000 resulted in realized prices that were
102 and 84 percent, respectively, of what otherwise would have been
received.

Construction Materials and Mining

     Earnings for the construction materials and mining business
decreased largely due to lower earnings at the construction
materials operations as a result of normal seasonal losses realized
in the first quarter of 2001 by businesses acquired since the
comparable period last year and higher interest expense resulting
from higher acquisition-related borrowings.  Also adding to the
earnings decline were increased selling, general and administrative
costs and decreased construction activity, due to weather-related
delays, partially offset by increased aggregate and ready-mixed
concrete volumes at existing construction materials operations.
Earnings at the coal operations improved mainly due to increased
coal volumes.

economic supplies of natural gas. Other important factors include
the level of governmental expenditures on public projects and the
timing of such projects, changes in anticipated tourism levels, the
effects of competition (including but not limited to electric retail
wheeling and transmission costs and prices of alternate fuels and
system deliverability costs), natural gas and oil commodity prices,
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, ability to
acquire natural gas and oil properties, and the availability of
economic expansion or development opportunities.

     The business and profitability of the company are also
influenced by economic and geographic factors, including political
and economic risks, changes in and compliance with environmental and
safety laws and policies, weather conditions, population growth
rates and demographic patterns, market demand for energy from plants
or facilities, changes in tax rates or policies, unanticipated
project delays or changes in project costs, unanticipated changes in
operating expenses or capital expenditures, labor negotiations or
disputes, changes in credit ratings or capital market conditions,
inflation rates, inability of the various counterparties to meet
their contractual obligations, changes in accounting principles
and/or the application of such principles to the company, changes in
technology and legal proceedings, and the ability to effectively
integrate the operations of acquired companies.

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 major
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.

MDU Resources Group, Inc.

* The company anticipates that its earnings per share growth rate
  from operations for 2001 will be in excess of 25 percent.

* Earnings per share, diluted, from operations for 2001 are
  projected in the $2.30 to $2.50 range, excluding a gain from the
  sale of the company's coal operations.

* The company expects the percentage of 2001 earnings per share
  from operations for the following quarters to be in the following
  approximate ranges:

  -    Second Quarter:  20 to 25 percent
  -    Third Quarter:   30 to 35 percent
  -    Fourth Quarter:  20 to 25 percent

* The company expects to issue and sell equity from time to time
  to keep its debt at the nonregulated businesses at no more than 40
  percent of total capitalization.

* Based on existing operations and current accounting rules,
  annual goodwill amortization expense is expected to be approximately
  $4.7 million.

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.
  Currently, a smaller town in western North Dakota is considering
  municipalization of Montana-Dakota's electric facilities.  Montana-
  Dakota is vigorously contesting any such proposal but is currently
  unable to determine the ultimate outcome of any such proceeding.
  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.

* Due to growing electric demand, a gas-fired 40-megawatt
  electric plant may be added in the three to five year planning
  horizon.

* Currently, the company is working with the North Dakota Lignite
  Research Council to determine the feasibility of constructing a 500
  megawatt class lignite-fired power plant in western North Dakota.

Natural gas distribution

* Annual natural gas throughput for 2001 is expected to be
  approximately 55 million decatherms, with about 39 million
  decatherms from sales and 16 million from transportation.

* The number of natural gas retail customers at existing
  operations is expected to grow by approximately 1.5 to 2 percent on
  an annual basis over the next three to five years.

* This business segment expects growth in sales of new value-
  added products and services, such as appliance repair contracts and
  home security systems.

Utility services

* This segment is growing both internally and through acquisitions of
  utility services companies.  The company's strategy is to acquire
  utility services businesses that are well managed, have excellent
  reputations and are growth-driven.

* Revenues for the utility services segment are expected to exceed
  $300 million in 2001.

* This business segment's goal is to achieve compound annual revenue
  and earnings growth rates of approximately 20 to 25 percent over the
  next five years.

Pipeline and energy services

* Two pipeline projects related to the company's coal bed natural
  gas drilling program in the Powder River Basin of Wyoming and
  Montana were completed in 2000.  The two projects provide the
  pipeline company the ability to move approximately 40 percent more
  coal bed natural gas through its system than has historically been
  transported, as well as enabling additional deliveries to other
  pipeline systems.  The largest project involved building a 75-mile,
  nonregulated pipeline through the heart of the basin, to move gas
  produced from throughout the Powder River Basin to interconnecting
  pipeline systems, including the company's own transmission system.

* In 2001, natural gas throughput for this segment is expected to
  increase by approximately 10 to 20 percent.

* This segment continues business development activities looking
  for assets and resources or system expansions that add value to
  existing operations through further vertical integration of its
  natural gas delivery and storage systems.

Natural gas and oil production

* The 2001 drilling program is projected to include over 500
  wells, 90 percent of which are expected to be drilled on company
  operated properties and the emphasis will continue to be on natural
  gas.  The 2001 drilling program is expected to be the single largest
  drilling program in the company's history.

* During the first quarter of 2001, 159 wells were drilled, 98
  percent of which were completed.

* Combined natural gas and oil production in 2000 totaled 40.5
  Bcf equivalents - a daily average of 111,000 Mcf equivalents.  For
  the month of March 2001, combined production averaged 135,500 Mcf
  equivalents per day, which was 38 percent higher than March 2000.

* Currently, there are approximately 165 wells producing in the
  Powder River Basin of Wyoming and Montana.  For the month of March,
  gross production averaged 19,200 Mcf equivalents per day.

* Combined natural gas and oil production at this business
  segment is expected to be approximately 30 percent higher in 2001
  than in 2000.

* The company's estimates for natural gas prices in the Rocky
  Mountain region for April through December 2001 are in the range of
  $3.15 to $4.15 per Mcf.  The company's estimates for natural gas
  prices on the NYMEX for April through December 2001 are in the range
  of $3.75 to $4.75 per Mcf.

* The company's estimates for NYMEX crude oil prices are in the
  range of $23 to $27 per barrel for April through December 2001.

* This business segment has entered into hedging arrangements for
  a portion of its 2001 production.  The company has entered into swap
  agreements and fixed price forward sales representing approximately
  25 to 30 percent of 2001 estimated annual natural gas production.
  Natural gas swap prices range from $4.57 to $5.39 per Mcf based on
  NYMEX and $4.04 to $4.44 per Mcf for Rocky Mountain gas sales.  In
  addition, approximately 35 to 40 percent of 2001 estimated annual
  oil production is hedged at NYMEX prices ranging from $27.51 to
  $29.22 per barrel.

* This business segment has entered into a hedging arrangement
  for a portion of its 2002 production.  The company has entered into
  an oil swap agreement at an average NYMEX price of $25.25 per
  barrel. This swap agreement represents approximately 8 percent of
  the company's 2002 estimated annual oil production.  At this time,
  the company has not entered into any natural gas swap agreements for
  2002 natural gas production. However, the company has approximately
  10 percent of its estimated 2002 annual natural gas production under
  fixed price forward sales.

Construction materials and mining

* On May 11, 2001, the company announced that the sale of its coal
  operations to Westmoreland Coal Company for $28.8 million in cash,
  excluding final settlement cost adjustments, has been finalized.
  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 will record
  a gain from the sale in the second quarter of 2001.  The company's
  estimate of the gain on the sale of the coal operations is in the
  range of $4 million to $8 million after tax and is subject to various
  post-closing adjustments.  While the sale will add to the company's
  2001 earnings, future earnings will be decreased as a result of the
  loss of earnings from the coal operations.  Earnings from coal
  operations would normally be expected to contribute less than
  10 percent of annual earnings of the construction materials
  and mining segment.

* The construction materials and mining business estimates that
  it currently has nearly one billion tons of economically recoverable
  aggregate reserves.  These reserves are strategically located and
  represent more than a 40-year supply at current consumption levels.

* Including the effects of acquisitions completed in 2000 and
  2001, aggregate, asphalt and ready-mixed concrete volumes are
  expected to increase by approximately 35 to 45 percent, 80 to 90
  percent and 35 to 45 percent, respectively, in 2001.

* As of mid-April, the construction materials and mining unit had
  approximately $197 million in backlog.

* This segment expects to achieve compound annual revenue and
  earnings growth rates of approximately 10 to 20 percent over the
  next five years.

* Earnings are expected to increase from a combination of
  acquisitions and by optimizing both synergies and improvements at
  existing operations.

Liquidity and Capital Commitments

     Net capital expenditures for the year 2001 are estimated at
$354.1 million, including those for acquisitions to date, system
upgrades, routine replacements, service extensions, routine
equipment maintenance and replacements, pipeline and gathering
expansion projects, the building of construction materials handling
and transportation facilities, the further enhancement of natural
gas and oil production and reserve growth and for potential future
acquisitions.  The company continues to evaluate potential future
acquisitions; however, these acquisitions are dependent upon the
availability of economic opportunities and, as a result, actual
acquisitions and capital expenditures may vary significantly from
the estimated 2001 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, the company's $40 million revolving credit and term
loan agreement, none of which is outstanding at March 31, 2001, 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 2001 capital expenditures referred to above
include two completed 2001 acquisitions including a construction
materials and mining company based in Minnesota that was acquired in
mid-April 2001 and a utility services company based in Missouri that
was acquired in early January 2001.  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.

     Centennial, a direct wholly owned subsidiary of the company,
has a revolving credit agreement with various banks on behalf of its
subsidiaries that supports $315 million of Centennial's $325 million
commercial paper program.  Under the commercial paper program,
$192.9 million was outstanding at March 31, 2001. The commercial
paper borrowings are classified as long term as Centennial intends
to refinance these borrowings on a long-term basis through continued
commercial paper borrowings supported by the revolving credit
agreement due September 29, 2003.  Centennial intends to renew this
existing credit agreement on an annual basis.

     Centennial has an uncommitted long-term master shelf agreement
on behalf of its subsidiaries that allows for borrowings of up to
$200 million.  Under the master shelf agreement, $150 million was
outstanding at March 31, 2001.

     On March 6, 2001, the company reported the sale of 358,429
shares of the company's Common Stock to Paul Revere Capital Partners
Ltd. (Paul Revere), pursuant to a purchase agreement by and between
the company and Paul Revere.  The company received proceeds from
this sale of $10 million.  These proceeds were used for refunding of
outstanding debt obligations and for other general corporate
purposes.

     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 March 31, 2001, the company could have issued
approximately $297 million of additional first mortgage bonds.

     The company's coverage of fixed charges including preferred
dividends was 4.5 times and 4.1 times for the twelve months ended
March 31, 2001, and December 31, 2000, respectively.  Additionally,
the company's first mortgage bond interest coverage was 9.0 times
and 8.3 times for the twelve months ended March 31, 2001, and
December 31, 2000, respectively.  Common stockholders' equity as a
percent of total capitalization was 57 percent and 54 percent at
March 31, 2001, and December 31, 2000, respectively.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     There are no material changes in market risk faced by the
company from those reported in the company's Annual Report on Form
10-K for the year ended December 31, 2000.  For more information on
market risk, see Part II, Item 7A in the company's Annual Report on
Form 10-K for the year ended December 31, 2000, and Notes to

                    PART II -- OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

     On March 5, 2001, the North Dakota District Court entered
a final judgment on the July 2000 order granting the motions for
summary judgment to dismiss the claims of the 11 natural gas
producers. On May 4, 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.

     Upon motion of plaintiffs, the Quinque case has been remanded
to State District Court for Stevens County, Kansas.

     For more information on the above legal actions see Note 9 of
Notes to Consolidated Financial Statements.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

     Between January 1, 2001 and March 31, 2001, the company issued
264,728 shares of Common Stock, $1.00 par value, as part of the
consideration for all of the issued and outstanding capital stock
with respect to a business acquired during this period and as a
final adjustment with respect to an acquisition in a prior period.
The Common Stock issued by the company in these transactions was
issued in private sales exempt from registration pursuant to
Section 4(2) of the Securities Act of 1933.  The former owners of
the businesses acquired, and now shareholders of the company, are
accredited investors and have acknowledged that they would hold the
company's Common Stock as an investment and not with a view to
distribution.
