                     NOTES TO CONSOLIDATED
                      FINANCIAL STATEMENTS

                    March 31, 2000 and 1999
                           (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, 1999 (1999 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 1999 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.  For
     the three months ended March 31, 2000 and 1999,
     comprehensive income equaled net income as reported.

 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

 4.  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 common stockholders' equity as previously reported.

 5.  New accounting pronouncements

         In June 1998, the Financial Accounting Standards Board
     (FASB) issued Statement of Financial Accounting Standards
     No. 133, "Accounting for Derivative Instruments and Hedging
     Activities" (SFAS No. 133).  SFAS No. 133 establishes
     accounting and reporting standards requiring that every
     derivative instrument (including certain derivative
     instruments embedded in other contracts) be recorded in the
     balance sheet as either an asset or liability measured at
     its fair value.  SFAS No. 133 requires that changes in the
     derivative's fair value be recognized currently in earnings
     unless specific hedge accounting criteria are met.  Special
     accounting for qualifying hedges allows a derivative's 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.

         In June 1999, the FASB issued Statement of Financial
     Accounting Standards No. 137, "Accounting for Derivative
     Instruments and Hedging Activities -- Deferral of the
     Effective Date of FASB Statement No. 133," which delayed the
     effective date of SFAS No. 133 to fiscal years beginning
     after June 15, 2000.  The company will adopt SFAS No. 133 on
     January 1, 2001.  The company continues to evaluate the
     effect of adopting SFAS No. 133 but has not yet determined
     what impact this adoption will have on the company's
     financial position or results of operations.

         In December 1999, the Securities and Exchange
     Commission issued Staff Accounting Bulletin No. 101,
     "Revenue Recognition" (SAB No. 101), which provides guidance
     on the recognition, presentation and disclosure of revenue
     in financial statements. On March 24, 2000, the Securities
     and Exchange Commission delayed the adoption date of SAB No.
     101.  SAB No. 101 is effective no later than the second
     fiscal quarter of the fiscal year beginning after December
     15, 1999.  SAB No. 101 is not expected to have a material
     effect on the company's financial position or results of
     operations.

 6.  Derivatives

         From time to time, the company utilizes derivative
     financial instruments, including price swap and collar
     agreements and natural gas futures, to manage a portion of
     the market risk associated with fluctuations in the price of
     oil and natural gas.  The company's policy prohibits the use
     of derivative instruments for trading purposes and the
     company has procedures in place to monitor compliance with
     its policies.  The company is exposed to credit-related
     losses in relation to financial instruments in the event of
     nonperformance by counterparties, but does not expect any
     counterparties to fail to meet their obligations given their
     existing credit ratings.

         The swap and collar agreements call for the company to
     receive monthly payments from or make payments to
     counterparties based upon the difference between a fixed and
     a variable price as specified by the agreements.  The
     variable price is either an oil price quoted on the New York
     Mercantile Exchange (NYMEX) or a quoted natural gas price on
     the NYMEX, Colorado Interstate Gas Index or other various
     indexes.  The company believes that there is a high degree
     of correlation because the timing of purchases and
     production and the swap and collar agreements are closely
     matched, and hedge prices are established in the areas of
     operations.  Amounts payable or receivable on the swap and
     collar agreements are matched and reported in operating
     revenues on the Consolidated Statements of Income as a
     component of the related commodity transaction at the time
     of settlement with the counterparty.  Gains or losses on
     futures contracts are deferred until the underlying
     commodity transaction occurs, at which point they are
     reported in "Purchased natural gas sold" on the Consolidated
     Statements of Income.

         The following table summarizes hedge agreements entered
     into by certain wholly owned subsidiaries of WBI Holdings as
     of March 31, 2000.  These agreements call for the
     subsidiaries of WBI Holdings to receive fixed prices and pay
     variable prices.

         The fair value of these derivative financial
     instruments reflects the estimated amounts that the company
     would receive or pay to terminate the contracts at the
     reporting date, thereby taking into account the current
     favorable or unfavorable position on open contracts.  The
     favorable or unfavorable position is currently not recorded
     on the company's financial statements.  Favorable and
     unfavorable positions related to commodity hedge agreements
     are expected to be generally offset by corresponding
     increases and decreases in the value of the underlying
     commodity transactions.

         In the event a derivative financial instrument does not
     qualify for hedge accounting or when the underlying
     commodity transaction matures, is sold, is extinguished, or
     is terminated, the current favorable or unfavorable position
     on the open contract would be included in results of
     operations.  The company's policy requires approval to
     terminate a hedge agreement prior to its original maturity.
     In the event a hedge agreement is terminated, the realized
     gain or loss at the time of termination would be deferred
     until the underlying commodity transaction is sold or
     matures and is expected to generally offset the
     corresponding increases or decreases in the value of the
     underlying commodity transaction.

 7.  Common stock

         At the Annual Meeting of Stockholders held on April 27,
     1999, the company's common stockholders approved an
     amendment to the Certificate of Incorporation increasing the
     authorized number of common shares from 75 million shares to
     150 million shares and reducing the par value of the common
     stock from $3.33 per share to $1.00 per share.

 8.  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.  Prior to
     the fourth quarter of 1999, the company reported five
     operating segments consisting of electric, natural gas
     distribution, natural gas transmission, construction
     materials and mining, and oil and natural gas production.
     During the fourth quarter of 1999, the company revised the
     components of the segments reported based on organizational
     changes and the significance of current segments.  As a
     result, a utility services segment was separated from the
     electric segment; gas production activities previously
     included in the natural gas transmission segment are now
     reflected in the oil and natural gas production segment; and
     the remaining operations of the natural gas transmission
     business were renamed pipeline and energy services.

         The company's operations are now conducted through six
     business segments and all prior period information has been
     restated to reflect this change.  As of March 31, 2000, all
     of the company's operations are located within the United
     States.  The electric business generates, transmits and
     distributes electricity and the natural gas distribution
     business distributes natural gas, and these operations also
     supply related value-added products and services in the
     Northern Great Plains.  The utility services business is a
     full-service engineering, design and build company operating
     in the western United States specializing in construction
     and maintenance of power and natural gas distribution and
     transmission systems as well as communication and fiber
     optic facilities.  The pipeline and energy services business
     provides natural gas transportation, underground storage and
     gathering services through regulated and nonregulated
     pipeline systems and provides energy marketing and
     management services throughout the United States.  The oil
     and natural gas production business is engaged in oil and
     natural gas acquisition, exploration and production
     throughout the United States and in the Gulf of Mexico.  The
     construction materials and mining business mines and markets
     aggregates and related value-added construction materials
     products and services in the western United States,
     including Alaska and Hawaii.  It also operates lignite coal
     mines in Montana and North Dakota.

       Segment information follows the same accounting policies
     as described in Note 1 of the company's 1999 Annual Report.

 9.  Regulatory matters and revenues subject to refund

         In June 1995, Williston Basin Interstate Pipeline
     Company (Williston Basin), an indirect wholly owned
     subsidiary of the company, filed a general rate increase
     application with the Federal Energy Regulatory Commission
     (FERC).  As a result of FERC orders issued after Williston
     Basin's application was filed, Williston Basin filed revised
     base rates in December 1995 with the FERC.  Williston Basin
     began collecting such increase effective January 1, 1996,
     subject to refund.  In July 1998, the FERC issued an order
     which addressed various issues including storage cost
     allocations, return on equity and throughput.  In August
     1998, Williston Basin requested rehearing of such order.  In
     June 1999, the FERC issued an order approving and denying
     various issues addressed in Williston Basin's rehearing
     request, and also remanding the return on equity issue to an
     Administrative Law Judge for further proceedings.  In July
     1999, Williston Basin requested rehearing of certain issues
     which were contained in the June 1999 FERC order.  In
     September 1999, the FERC granted Williston Basin's request
     for rehearing with respect to the return on equity issue but
     also ordered Williston Basin to issue interim refunds prior
     to the final determination in this proceeding.  As a result,
     in October 1999, Williston Basin issued refunds to its
     customers totaling $11.3 million, all from amounts which had
     previously been reserved.  In December 1999, a hearing was
     held before the FERC regarding the return on equity issue.
     In April 2000, the Administrative Law Judge issued an
     Initial Decision regarding the remanded return on equity
     issue and Williston Basin is currently evaluating its
     options regarding this decision.  In addition, in July 1999,
     Williston Basin appealed to the United States Court of
     Appeals for the D.C. Circuit (D.C. Circuit Court) certain
     issues concerning storage cost allocations as decided by the
     FERC in its June 1999 order.  In October 1999, the D.C.
     Circuit Court issued an order which dismissed Williston
     Basin's appeal but permitted Williston Basin to again appeal
     such previously contested issues upon final determination of
     all issues by the FERC in this proceeding.

         In December 1999, Williston Basin filed a general
     natural gas rate change application with the FERC.
     Williston Basin will begin collecting such rates effective
     June 1, 2000, subject to refund.

         Reserves have been provided for a portion of the
     revenues that have been collected subject to refund with
     respect to pending regulatory proceedings and to reflect
     future resolution of certain issues with the FERC.
     Williston Basin believes that such reserves are adequate
     based on its assessment of the ultimate outcome of the
     various proceedings.

 10. Litigation

         In March 1997, 11 natural gas producers filed suit in
     North Dakota Northwest 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 allege they are entitled to damages
     for the breach of Williston Basin's and the company's
     contracts with Koch although no specific damages have been
     stated.  A similar suit was filed by Apache Corporation
     (Apache) and Snyder Oil Corporation (Snyder) in North Dakota
     District Court in December 1993.  The North Dakota Supreme
     Court in December 1999 affirmed the North Dakota 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 have filed motions for
     summary judgment to dismiss the claims of the 11 natural gas
     producers.  Oral argument on those motions was held May 8,
     2000.  Williston Basin and the company are awaiting a
     decision from the North Dakota District Court.  A trial on
     the claims of the natural gas producers has been set to
     commence on October 23, 2000.

         In Williston Basin's opinion, the claims of the 11
     natural gas producers are without merit.  If any amounts are
     ultimately found to be due, Williston Basin plans to file
     with the FERC for recovery from customers.  However, the
     amount of costs that can ultimately be recovered is subject
     to approval by the FERC and market conditions.

         In June 1999, several oil and gas royalty interest
     owners filed suit in Colorado State District Court, in the
     City and County of Denver, against WBI Production, Inc. (WBI
     Production), an indirect wholly owned subsidiary of the
     company, and several former producers of natural gas with
     respect to certain gas production properties in the state of
     Colorado.  The complaint arose as a result of the purchase
     by WBI Production, effective January 1, 1999, of certain
     natural gas producing leaseholds from the former producers.
     Prior to February 1, 1999, the natural gas produced from the
     leaseholds was sold at above market prices pursuant to a
     natural gas contract.  Pursuant to the contract, the royalty
     interest owners were paid royalties based upon the above
     market prices. The royalty interest owners have alleged that
     WBI Production took assignment of the rights to the natural
     gas contract from the former owner of the contract and, with
     respect to natural gas produced from such leases and sold at
     market prices thereafter, wrongly ceased paying the higher
     royalties on such gas.

         In their complaint, the royalty interest owners have
     alleged, in part, breach of oil and gas lease obligations
     and unjust enrichment on the part of WBI Production and the
     other former producers with respect to the amount of
     royalties being paid to the royalty interest owners.  The
     royalty interest owners have requested damages under
     alternate theories of up to approximately $11.6 million for
     additional royalties, excluding interest.  Motions for
     summary judgment are pending.  Trial before the Colorado
     State District Court had been scheduled to be held during
     the week of April 24, 2000, but was rescheduled for the week
     of October 2, 2000.  WBI Production is vigorously contesting
     the suit.

         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 D.C.
     Circuit Court 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 on March 17, 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.

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

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

    Prior to the fourth quarter of 1999, the company reported
five operating segments consisting of electric, natural gas
distribution, natural gas transmission, construction materials
and mining, and oil and natural gas production.  During the
fourth quarter of 1999, the company revised the components of the
segments reported based on organizational changes and the
significance of current segments.  As a result, a utility
services segment was separated from the electric segment; gas
production activities previously included in the natural gas
transmission segment are now reflected in the oil and natural gas
production segment; and the remaining operations of the natural
gas transmission business were renamed pipeline and energy
services.

    The company's operations are now conducted through six
business segments and all prior period information has been
restated to reflect this change.  For purposes of segment
financial reporting and discussion of results of operations,
electric and natural gas distribution include the electric and
natural gas distribution operations of Montana-Dakota. Utility
services includes all the operations of Utility Services, Inc.
Pipeline and energy services includes WBI Holdings'
transportation, storage, gathering and energy marketing and
management services.  Oil and natural gas production includes the
oil and natural gas acquisition, exploration, development and
production operations of WBI Holdings, while construction
materials and mining includes the results of Knife River's
operations.

Three Months Ended March 31, 2000 and 1999

    Consolidated earnings for the quarter ended March 31, 2000,
increased $700,000 from the comparable period a year ago due
to higher earnings at the oil and natural gas production
business, largely offset by lower earnings at all 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 oil and natural gas
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:  $24.6 million, $24.4 million and $.2 million for the
three months ended March 31, 2000; and $23.4 million, $23.3
million and $.1 million for the three months ended March 31,
1999, respectively.

Three Months Ended March 31, 2000 and 1999

Electric

    Electric earnings decreased due to higher retail fuel and
purchased power costs largely due to increased generation at
higher cost versus lower cost generating stations and increased
purchases from outside suppliers, both resulting from outages at
a large electric generating station.  Also contributing to the
earnings decline were higher operation and maintenance expenses
resulting from increased payroll expense, and higher maintenance
costs at a large electric generating station, partially offset by
lower employee benefit-related costs.  Higher average realized
rates on sales for resale slightly offset the earnings decline.

Natural Gas Distribution

    Earnings decreased at the natural gas distribution
business due to increased operation and maintenance expenses,
primarily higher payroll expense and increased subcontractor
costs partially offset by lower employee benefit-related
costs.  The natural gas distribution business continued to
experience lower than normal volumes resulting from weather
that was 13 percent warmer than normal.  Higher service and
repair income partially offset the earnings decrease.

Utility Services

    Utility services earnings declined due to decreased workload
at some of the existing operations that have been affected by
utility merger activity in the Pacific Northwest, partially
offset by earnings from companies acquired since the comparable
period last year.

Pipeline and Energy Services

    Earnings at the pipeline and energy services business
decreased due to the recognition in 1999 of $1.7 million
resulting from a favorable order received from the D.C. Circuit
Court relating to a 1992 general rate proceeding.  Increased
operating costs, primarily higher payroll expense, depreciation
expense and other taxes also added to the earnings decrease.
Increased transportation to off-system and on-system markets
partially offset by decreased transportation to storage, and
earnings from acquisitions since the comparable period last year
partially offset the earnings decrease.  The increase in energy
services revenue and the related increase in purchased natural
gas sold resulted from increased energy marketing volumes.

Oil and Natural Gas Production

    Earnings for the oil and natural gas production business
increased primarily as a result of increased operating
revenues resulting from realized oil and natural gas prices
which were 112 percent and 38 percent higher than last year,
respectively.  Higher natural gas production due to both a new
acquisition and ongoing development of existing properties
also added to the earnings increase.  Partially  offsetting
the earnings improvement were higher production taxes,
largely the result of higher commodity prices.

Construction Materials and Mining

    Construction materials and mining earnings decreased due to
normal seasonal losses realized in the first quarter of 2000 by
construction materials businesses acquired since the comparable
period last year, partially offset by increased construction
activity at existing construction materials operations.  Higher
aggregate, ready-mixed concrete and construction volumes, were
partially offset by higher selling, general and administrative
costs at the existing construction materials operations.
Decreased coal volumes sold resulting from outages at a large
electric generating station also added to the earnings decline.

statement or statements to reflect events or circumstances that
occur after the date on which such statement is made or to
reflect the occurrence of unanticipated events.  New factors
emerge from time to time, and it is not possible for management
to predict all of such factors, nor can it assess the effect of
each such factor on the company's business or the extent to which
any such factor, or combination of factors, may cause actual
results to differ materially from those contained in any forward-
looking statement.

    In addition to other factors and matters discussed elsewhere
herein, some important factors that could cause actual results or
outcomes for the company to differ materially from those
discussed in forward-looking statements include prevailing
governmental policies and regulatory actions with respect to
allowed rates of return, financings, or industry and rate
structures, acquisition and disposal of assets or facilities,
operation and construction of plant facilities, recovery of
purchased power and purchased gas costs, present or prospective
generation and availability of economic supplies of natural gas.
Other important factors include the level of governmental
expenditures on public projects and project schedules, 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), oil and natural gas commodity prices, drilling successes
in oil and natural gas operations, ability to acquire oil and
natural gas 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 obligations with
respect to the company's financial instruments, 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

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

    In January 2000, the company announced an agreement to
acquire Great Plains Natural Gas Company (Great Plains).  Great
Plains is a natural gas distribution company serving 19
communities in western Minnesota and southeastern North Dakota.
The North Dakota Public Service Commission has approved the
acquisition and approval is currently pending with the Minnesota
Public Utilities Commission.

    Also in January 2000, the company announced that the Board
of Directors had approved the acquisition of Connolly-Pacific
Co., a southern California aggregate mining and marine
construction company.  Thomas Everist, a member of the company's
Board of Directors, has an interest in L.G. Everist,
Incorporated, which has owned Connolly-Pacific Co. since 1977.
At the company's Annual Meeting of Stockholders held on April 25,
2000, in accordance with New York Stock Exchange rules, the
acquisition was approved by the stockholders of the company.

    In addition, in April 2000, the company acquired ready-mixed
concrete companies in Montana and a pipeline and cable locating
technology company based in Texas.  Substantially all of the
assets of a natural gas exploration and production company
headquartered in Colorado, specializing in the development of
coal bed methane reserves on over 187,000 net acres under lease
in the Powder River Basin of Wyoming and Montana were also
acquired.  None of the above acquisitions were individually
material.

Liquidity and Capital Commitments

    Net capital expenditures for the year 2000 are estimated at
$355.3 million, including those for acquisitions to date, system
upgrades, routine replacements, service extensions, routine
equipment maintenance and replacements, pipeline expansion
projects, the building of construction materials handling and
transportation facilities, and the further enhancement of oil and
natural gas production and reserve growth. 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, existing lines of credit aggregating $7.2 million, a
commercial paper credit facility at Centennial, as described
below, and through the issuance of long-term debt and the
company's equity securities.  At March 31, 2000, $24 million
under the revolving credit and term loan agreement and $6.3
million under the lines of credit were outstanding.

    Centennial, a direct wholly owned subsidiary of the company,
has a revolving credit agreement with various banks on behalf of
its subsidiaries that supports the $250 million Centennial
commercial paper program.  Under the commercial paper program,
$172.3 million was outstanding at March 31, 2000.  The commercial
paper borrowings are classified as long term as the company
intends to refinance these borrowings on a long term basis
through continued commercial paper borrowings supported by the
revolving credit agreement due September 1, 2002.  The company
intends to renew this existing credit agreement on an annual
basis.

    Centennial entered into 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, $25 million was outstanding at March 31, 2000.

    The estimated 2000 capital expenditures set forth above for
electric, natural gas distribution, utility services, pipeline
and energy services and construction materials and mining
operations do not include potential future acquisitions.  The
company continues to seek additional growth opportunities,
including investing in the development of related lines of
business.  To the extent that acquisitions occur, the company
anticipates that such acquisitions would be financed with
existing credit facilities and the issuance of long-term debt and
the company's equity securities.

    In January 2000, the company announced that its Board of
Directors approved a stock repurchase program, authorizing the
purchase of up to 1 million shares of the company's outstanding
common stock.  The amount and timing of purchases will depend on
market conditions.  It is anticipated that the funds required for
this program will be met from internally generated funds, the
issuance of long-term or short-term debt or other sources that
become available from time to time.  Unless extended, the stock
repurchase program will be terminated on or prior to December 31,
2001.  As of March 31, 2000, no shares have been repurchased
under the program.

    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, 2000, the company could have
issued approximately $285 million of additional first mortgage
bonds.

    The company's coverage of fixed charges including preferred
dividends was 4.2 times and 4.3 times for the twelve months ended
March 31, 2000, and December 31, 1999, respectively.
Additionally, the company's first mortgage bond interest coverage
was 6.9 times and 7.1 times for the twelve months ended March 31,
2000, and December 31, 1999, respectively.  Common stockholders'
equity as a percent of total capitalization was 56 percent and 54
percent at March 31, 2000, and December 31, 1999, 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, 1999.  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, 1999,
and Notes to Consolidated Financial Statements in this Form 10-Q.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

    On January 28, 2000, the company issued 18,252 shares of
Common Stock, $1.00 par value, as part of a final adjustment with
respect to an acquisition of a business in a prior period.  The
Common Stock issued by the company in this transaction was issued
in a private sale exempt from registration pursuant to
Section 4(2) of the Securities Act of 1933.  The former owners of
the business 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.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS
