                       FINANCIAL STATEMENTS

                   JuneSeptember 30, 1998 and 1997
                          (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, 1997
(1997 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 1997 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. 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.

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

4.  Common stock split

    On May 14, 1998, the Company's Board of Directors approved
a three-for-two common stock split to be effected in the form of a
50 percent common stock dividend.  The additional shares of common
stock were distributed on July 13, 1998, to common stockholders of
record on July 3, 1998.  All common stock information appearing in
the accompanying consolidated financial statements has been
restated to give retroactive effect to the stock split.
Additionally, preference share purchase rights have been
appropriately adjusted to reflect the effects of the split.

5. New Accounting changePronouncements

    On January 1, 1998, the Company adopted Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" (SFAS No. 130).  SFAS No. 130 provides authoritative
guidance on the reporting and display of comprehensive income
and its components.  For the three months and sixnine months ended
JuneSeptember 30, 1998, comprehensive income equaled net income as
reported.

    In June 1998, the Financial Accounting Standards Board
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.

    SFAS No. 133 is effective for fiscal years beginning after
June 15, 1999.  SFAS No. 133 must be applied to derivative
instruments and certain derivative instruments embedded in hybrid
contracts that were issued, acquired, or substantively modified
after December 31, 1997.   The Company has not yet quantified
the impacts of adopting SFAS No. 133.

6. Write-down of oil and natural gas properties

    The Company uses the full-cost method of accounting for its
oil and natural gas production activities.  Under this method, all
costs incurred in the acquisition, exploration and development of
oil and natural gas properties are capitalized and amortized on the
units of production method based on total proved reserves.
Capitalized costs are subject to a "ceiling test" that limits such
costs to the aggregate of the present value of future net revenues
of proved reserves and the lower of cost or fair value of unproved
properties.  Future net revenue is estimated based on end-of-quarter
prices adjusted for contracted price changes.  If capitalized costs
exceed the full-cost ceiling at the end of any quarter, a permanent
write-down is required to be charged to earnings in that quarter.
Such a charge has no effect on the Company's cash flows.

    Due to significantly lower oil prices, the Company's
capitalized costs under the full-cost method of accounting exceeded
the full-cost ceiling at June 30, 1998.  The Company was required
to recognize a write-down of its oil and natural gas producing
properties.  This charge amounted to $33.1 million pretax and
reduced earnings for the three and sixnine months ended JuneSeptember 30, 1998 by
$20 million.

7.  Pending litigation

  W. A. Moncrief --

    In November 1993, the estate of W.A. Moncrief (Moncrief),
a producer from whom Williston Basin purchased a portion of its
natural gas supply, filed suit in Federal District Court for the
District of Wyoming (Federal District Court) against Williston
Basin and the Company disputing certain price and volume issues
under the contract.

    Through the course of this action Moncrief submitted damage
calculations which totaled approximately $19 million or, under its
alternative pricing theory, approximately $39 million.

    In June 1997, the Federal District Court issued its order
awarding Moncrief damages of approximately $15.6 million.  In July
1997, the Federal District Court issued an order limiting
Moncrief's reimbursable costs to post-judgment interest, instead of
both pre- and post-judgment interest as Moncrief had sought.
In August 1997, Moncrief filed a notice of appeal with the United
States Court of Appeals for the Tenth Circuit (U.S. Court of
Appeals) related to the Federal District Court's orders.  In
September 1997, Williston Basin and the Company filed a notice of
cross-appeal.  Oral argument before the U.S. Court of Appeals has been scheduled forwas
held September 23, 1998.  Williston Basin and the Company are
awaiting a decision from the U.S. Court of Appeals.

    Williston Basin believes that it is entitled to recover
from ratepayerscustomers virtually all of the costs which might
ultimately be incurred as a result of this litigation as gas supply
realignment transition costs pursuant to the provisions of the
Federal Energy Regulatory Commission's (FERC) Order 636.  However,
the amount of costs that can ultimately be recovered is subject to
approval by the FERC and market conditions.

  Apache Corporation/Snyder Oil Corporation --

    In December 1993, Apache Corporation (Apache) and Snyder
Oil Corporation (Snyder) filed suit in North Dakota Northwest
Judicial District Court (North Dakota District Court), against
Williston Basin and the Company.  Apache and Snyder are oil and
natural gas producers which had processing agreements with Koch
Hydrocarbon Company (Koch).  Williston Basin and the Company had a
natural gas purchase contract with Koch.  Apache and Snyder have
alleged they are entitled to damages for the breach of Williston
Basin's and the Company's contract with Koch.  Williston Basin
and the Company believe that if Apache and Snyder have any legal
claims, such claims are with Koch, not with Williston Basin or the
Company as Williston Basin, the Company and Koch have settled their
disputes.  Apache and Snyder have submitted damage estimates under
differing theories aggregating up to $4.8 million without interest.
A motion to intervene in the case by several other producers, all of
which had contracts with Koch but not with Williston Basin, was denied
in December 1996.  The trial before the North Dakota District Court
was completed in November 1997.  Williston Basin and the Company
are awaiting a decision from the North Dakota District Court.

    In a related matter, in March 1997, a suit was filed by
nine other producers, several of which had unsuccessfully tried to
intervene in the Apache and Snyder litigation, against Koch,
Williston Basin and the Company.  The parties to this suit are
making claims similar to those in the Apache and Snyder litigation,
although no specific damages have been stated.

    In Williston Basin's opinion, the claims of Apache and
Snyder are without merit and overstated and the claims of the nine
other producers are without merit.  If any amounts are ultimately
found to be due, Williston Basin plans to file with the FERC for
recovery from ratepayers.customers.

  Jack J. Grynberg --

    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 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.  The United States government, particularly officials from
the Departments of Justice and Interior, reviewed the complaint and
the evidence presented by Grynberg and declined to intervene in the
action, permitting Grynberg to proceed on his own.  In March 1997,
the U.S. District Court dismissed the suit without prejudice
against 53 of the defendants, including Williston Basin, on the
grounds that the parties were improperly joined in the suit and
that Grynberg's claim of fraud was not specific enough as it
related to any individual party to the suit.  On May 15, 1998,
Grynberg appealed the U.S. District Court's decision.  Williston
Basin believes Grynberg's claims are without meritjoined other defendants and intends to
vigorously contest this suit.filed a motion for summary
affirmance.  The motion was granted on October 6, 1998, and the
appeal was effectively dismissed.

  Coal Supply Agreement --

    In November 1995, a suit was filed in District Court,
County of Burleigh, State of North Dakota (State District Court) by
Minnkota Power Cooperative, Inc., Otter Tail Power Company,
Northwestern Public Service Company and Northern Municipal Power
Agency (Co-owners), the owners of an aggregate 75 percent interest
in the Coyote electric generating station (Coyote Station), against
the Company (an owner of a 25 percent interest in the Coyote
Station) and Knife River.  In its complaint, the Co-owners have
alleged a breach of contract against Knife River ofwith respect to
the long-term coal supply agreement (Agreement) between the owners
of the Coyote Station and Knife River.  The Co-owners have
requested a determination by the State District Court of the
pricing mechanism to be applied to the Agreement and have further
requested damages during the term of such alleged breach on the
difference between the prices charged by Knife River and the prices
that may ultimately be determined by the State District Court.  The
Co-
ownersCo-owners also alleged a breach of fiduciary duties by the Company
as operating agent of the Coyote Station, asserting essentially
that the Company was unable to cause Knife River to reduce its coal
price sufficiently under the Agreement, and the Co-owners are
seeking damages in an unspecified amount.  In May 1996, the State
District Court stayed the suit filed by the Co-owners pending
arbitration, as provided for in the Agreement.

    In September 1996, the Co-owners notified the Company and
Knife River of their demand for arbitration of the pricing dispute
that had arisen under the Agreement.  The demand for arbitration,
filed with the American Arbitration Association (AAA), did not make
any direct claim against the Company in its capacity as operator of
the Coyote Station.  The Co-owners  requested that the arbitrators
make a determination that the pricing dispute is not a proper
subject for arbitration.  By an  April 1997 order, the arbitration
panel concluded that the claims raised by the Co-owners are
arbitrable.  The Co-owners have requested the arbitrators to make
a determination that the prices charged by Knife River were
excessive and that the Co-owners should be awarded damages, based
upon the difference between the prices that Knife River charged and
a "fair and equitable" price, of approximately $50 million or more.price.  Upon application by the Company and
Knife River, the AAA administratively determined that the Company
was not a proper party defendant to the arbitration, and the
arbitration is proceeding against Knife River.  AOn October 9, 1998,
a hearing before the arbitration panel was completed.  At the
hearing the Co-owners requested damages of approximately $24
million, including interest, plus a reduction in the future price
of coal under the Agreement.  A decision from the arbitration panel
is currently scheduled for October 5, 1998.expected after the completion of a post-hearing briefing.
Although unable to predict the outcome of the arbitration, Knife
River and the Company believe that the Co-owners' claims are
without merit and intend to vigorously defend the prices charged
pursuant to the Agreement.

8.  Regulatory matters and revenues subject to refund

    Williston Basin had pending with the FERC a general natural
gas rate change application implemented in 1992.  In October 1997,
Williston Basin appealed to the U.S. Court of Appeals for the D.C.
Circuit (D.C. Circuit Court) certain issues decided by the FERC in
prior orders concerning the 1992 proceeding.  Oral argument before
the D.C. Circuit Court has been scheduled for November 19, 1998.
In December 1997, the FERC issued an order accepting, subject to
certain conditions, Williston Basin's July 1997 compliance filing.
In December 1997, Williston Basin submitted a compliance filing
pursuant to the FERC's December 1997 order and refunded $33.8
million to its customers, including $30.8 million to Montana-Dakota,
in addition to the $6.1 million interim refund that it had
previously made in November 1996.  All such amounts had been
previously reserved.  On March 25, 1998, the FERC issued an order
accepting Williston Basin's December 1997 compliance filing.

    In June 1995, Williston Basin filed a general rate increase
application with the 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 resulting in an
increase of $8.9 million or 19.1 percent over the then current
effective rates.  Williston Basin began collecting such increase
effective January 1, 1996, subject to refund.  On July 29, 1998,
the FERC issued an order which may be subject to rehearing.addressed various issues.  On August
28, 1998, Williston Basin is currently evaluating the implicationrequested rehearing of the
order and what option to pursue.such order.

    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.

9.  Natural gas repurchase commitment

    The Company has offered for sale since 1984 the inventoried
natural gas available under a repurchase commitment with Frontier
Gas Storage Company, as described in Note 3 of its 1997 Annual
Report.  As a part of the corporate realignment effected January 1,
1985, the Company agreed, pursuant to the settlement approved by
the FERC, to remove from rates the financing costs associated with
this natural gas.

    The FERC has issued orders that have held that storage
costs should be allocated to this gas, prospectively beginning
May 1992, as opposed to being included in rates applicable to
Williston Basin's customers.  These storage costs, as initially
allocated to the Frontier gas, approximated $2.1 million annually,
for which Williston Basin has provided reserves.  Williston Basin
appealed these orders to the D.C. Circuit Court which in December
1996 issued its order ruling that the FERC's actions in allocating
storage capacity costs to the Frontier gas were appropriate.  See Note 8 regardingOn
August 28, 1998, Williston Basin requested rehearing on the July
29, 1998 FERC order which addressesaddressed various issues, including thea
requirement that storage deliverability costs to be allocated to the
Frontier gas.

10. Environmental matters

    Montana-Dakota and Williston Basin discovered
polychlorinated biphenyls (PCBs) in portions of their natural gas
systems and informed the United States Environmental Protection
Agency (EPA) in January 1991.  Montana-Dakota and Williston Basin
believe the PCBs entered the system from a valve sealant.  In
January 1994, Montana-Dakota, Williston Basin and Rockwell
International Corporation (Rockwell), manufacturer of the valve
sealant, reached an agreement under which Rockwell has reimbursed
and will continue to reimburse Montana-Dakota and Williston Basin
for a portion of certain remediation costs.  On the basis of
findings to date, Montana-Dakota and Williston Basin  estimate
future environmental assessment and remediation costs will aggregate
$3 million to $15 million.  Based on such estimated cost, the
expected recovery from Rockwell and the ability of Montana-Dakota
and Williston Basin to recover their portions of such costs from
ratepayers, Montana-Dakota and Williston Basin believe that the
ultimate costs related to these matters will not be material to each
of their respective financial positions or results of operations.

12. Derivatives

    The Company, in connection with the operations of Williston Basin and Fidelity Oil hashave entered into certain
price swap and collar agreements (hedge agreements) to manage a portion of the market
risk associated with fluctuations in the price of oil and natural
gas.  These hedgeswap and collar agreements are not held for trading
purposes.  The hedgeswap and collar agreements call for the CompanyWilliston Basin
and Fidelity Oil 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 hedge 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 or Colorado
Interstate Gas Index.  The Company believes that there is a high
degree of correlation because the timing of purchases and production
and the hedgeswap and collar agreements are closely matched, and hedge
prices are established in the areas of the Company's operations.  Amounts payable
or receivable on hedgethe 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.  The amounts payable or
receivable are offset by corresponding increases and decreases in
the value of the underlying commodity transactions.

    Innovative Gas Services, Incorporated, an energy marketing
subsidiary of WBI Energy Services, Inc., participates in the natural
gas futures market to hedge a portion of the price risk associated
with natural gas purchase and sale commitments.  These futures are
not held for trading purposes.  Gains or losses on the futures
contracts are deferred until the  transaction occurs, at which point
they are reported in "Purchased natural gas sold" on the
Consolidated Statements of Income.  The gains or losses on the
futures contracts are offset by corresponding increases and
decreases in the value of the underlying commodity transactions.

    Knife River hashad entered into an interest rate swap
agreement, which expired in August 1998, to manage a portion of its
interest rate exposure on long-term debt.  This interest
rate swap agreement iswas not held for trading purposes.  The interest
rate swap agreement callscalled for Knife River to receive quarterly
payments from or make payments to counterparties based upon the
difference between fixed and variable rates as specified by the
interest rate swap agreement.  The variable prices arewere based on the
three-month floating London Interbank Offered Rate.  Settlement
amounts payable or receivable under this interest rate swap
agreement arewere recorded in "Interest expense" on the Consolidated
Statements of Income in the accounting period they arewere incurred.
The amounts payable or receivable arewere offset by interest on the
related debt instrument.

    The Company's policy prohibits the use of derivative
instruments for trading purposes and the Company has procedures in
place to monitor their use.  The Company is exposed to credit-related
losses in the event of nonperformance by counterparties to
these financial instruments, but does not expect any counterparties
to fail to meet their obligations given their existing credit
ratings.

    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 oil and natural gas hedge
agreements will be offset by corresponding increases and decreases
in the value of the underlying commodity transactions.  A favorable
or unfavorable position on the interest rate swap agreement will be
offset by interest on the related debt instrument.  The
Company's net favorable position on all swap and collarhedge agreements outstanding
at JuneSeptember 30, 1998, was $35,000.$358,000.  In the event a hedge agreement
does not qualify for hedge accounting or when the underlying
commodity transaction or related debt instrument 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 or related debt instrument is sold or matures
and would be offset by corresponding increases or decreases in the
value of the underlying commodity transaction or interest on the
related debt instrument.

Three Months Ended JuneSeptember 30, 1998 and 1997

    Consolidated earnings for the quarter ended JuneSeptember 30, 1998,
were down $14.5up $8.3 million from the comparable period a year ago due to
lowerhigher earnings at the construction materials and mining, natural
gas transmission and electric businesses.  Decreased earnings at the
oil and natural gas production business,
largely resulting from a $20 million after tax non-cash write-down
of oil and natural gas properties.  Decreased earnings at the
natural gas distribution
business also added to the earnings
decline.  Higher earnings at the construction materials and mining,
electric and natural gas transmission businesses partiallysomewhat offset the earnings decrease.

Nine Months Ended JuneSeptember 30, 1998 and 1997

    Consolidated earnings for the sixnine months ended JuneSeptember 30,
1998, were down $11.3$2.9 million from the comparable period a year ago
due to decreased earnings at the oil and natural gas production
business, largely resulting from the aforementioneda second quarter $20 million after
tax non-cash write-
downwrite-down of oil and natural gas properties, and lower
earnings at the natural gas distribution business.  Increased
earnings at the natural gas transmission, construction materials and mining, natural gas
transmission and electric businesses somewhat offset the earnings
decline.

was due to 1997 costs of $1.6 million associated with a ten-week
maintenance outage at the Coyote Station.  In addition, damages
caused by an April 1997 blizzard also added to the decline in
maintenance expense.  Increased purchased power demand charges

Hap Taylor & Sons, Inc. in July 1998.  Prior to August 1997, Knife
River's original 50 percent ownership interest in Hawaiian Cement
was accounted for under the equity method.  However, with the
acquisition mentioned above, Knife River began consolidating
Hawaiian Cement into its financial statements.  Operating income at

Oil and Natural Gas Production Operations

    Operating income for the oil and natural gas production business
decreased largely as a result of a $33.1 million ($20
million after tax) non-cash write-down oflower oil and natural gas
properties, as previously discussed in Note 6 of Notes to
Consolidated Financial Statements.  Lower oil and natural gas
revenues also added to the operating income decline.revenues. Decreased oil

sales for resale revenue and lower maintenance expense contributed
to the utility operating income increase.  Sales for resale revenue
increased due to 9382 percent higher volumes and higher margins of 3029
percent, both due to favorable market conditions.  The decrease in
maintenance expense was due to 1997 costs of $1.6$1.9 million associated
with a ten-week maintenance outage at the Coyote Station.  In
addition, damages caused by an April 1997 blizzard also added to the
decline in maintenance expense.expense for 1998.  Increased average realized

partially offset the operating income decline.

    Natural gas distribution earnings decreased due to the
previously discussed decline in operating income, partially offset
by increased service and repair income.

Natural Gas Transmission Operations

    Operating income at the natural gas transmission business
increased primarily due to increases in transportation revenues.
The increase in transportation revenue resulted from a $5.0 million
($3.1 million after tax) reversal of reserves in the first quarter
of 1998 for certain contingencies relating to a FERC order
concerning a compliance filing.  Higher transportationvolumes transported to
storage,
and off-system markets, somewhat offset by lower transportationvolumes transported to on-systemon- and
off-system markets, also added to the transportation revenue
improvement.  Higherand higher average discounted rates primarily off-system
transportation and gathering, also
contributed to the revenue increase.  In addition, transportation revenue increased due toLower production royalties
caused by a 1997 MMS royalty settlement, as previously discussed in
the absence of additional 1997 reserved revenues, with a corresponding
reduction in depreciation expense, as a result of FERC orders
relating to a 1992 general rate proceeding.  The revenue increase
was partially offset by the completion of the recovery of deferred

Increased energy marketing revenues, due to higher natural gas
volumes sold,three months discussion, also added to the operating income
increase.  In addition, higher average prices on company-owned
natural gas production added to the operating income improvement.
The increase in energy marketing revenue and the related increase
in purchased gas sold result from the acquisition of IGS in July
1998.

after tax) non-cash write-down of oil and natural gas properties,
as previously discussed in Note 6 of Notes to Consolidated Financial
Statements.  Lower oil and natural gas revenues also added to the
decrease in operating income.  Decreased oil revenue resulted from
a $5.0$6.7 million decline due to lower average prices and a $970,000$1.9
million decrease due to lower production.  The decrease in natural
gas revenue was due to a $2.1$2.8 million decline arising from lower
average prices and a $2.1$1.2 million reduction due to lower production.
Decreased operation and maintenance expenses, the result of lower
production and decreased well maintenance, partially offset the
decrease in operating income.  Depreciation,Decreased depreciation, depletion and
amortization decreased due to lower production, also somewhat offsetting the decline in operating
income.  In addition,and decreased taxes other than
income, decreased, mainly due to lower production taxes resulting from lower
commodity prices,
which also partially offset the operating income
decline.

    Earnings for this business unit decreased due to the decrease
in operating income.  Decreasedincome, partially offset by lower interest expense due to lower
average long-term debt balances slightly offset the decline in
earnings.and
decreased income taxes.

Year 2000 Compliance

    The year 2000 issue is the result of computer programs having
been written using two digits rather than four digits to define the
applicable year.  TheIn 1997, the Company is currently evaluating and will
continue to evaluate the potential effectsestablished a task force with
coordinators in each of the year 2000 issue
on its systems.  The Company is making and will continue to make
those modifications to its systems that it deems necessary or
desirable in ordermajor operating units to address the
year 2000 issueissue.  The scope of the year 2000 readiness effort
includes information technology (IT) and non-IT systems, including,
computer hardware, software, networking, communications, embedded
and micro-processor controlled systems, building controls and office
equipment.   The Company's year 2000 plan is based upon a six-phase
approach involving awareness, inventory, assessment, remediation,
testing and will continueimplementation.

State of Readiness --

    The Company is conducting a corporate-wide awareness program,
compiling an inventory of IT and non-IT systems, and assigning
priorities to test such modifications in ordersystems.  As of September 30, 1998, the awareness
and inventory phases, including assigning priorities to determine
whether they effectively mitigate potential problems.  BasedIT and non-
IT systems, have been substantially completed.

    The assessment phase involves the review of each inventory item
for year 2000 compliance and efforts to obtain representations and
assurances from third parties, including suppliers and vendors, that
such entities are year 2000 compliant.  As of September 30, 1998,
based on its
assessmentscontacts with and representations obtained from third
parties to date, the Company believes that the costs expectedis not aware of any material third
party year 2000 problems.  The Company will continue to be incurred specifically related to such modifications will not
be material to its resultscontact
third parties seeking written verification of operations.  Failure byyear 2000 readiness.
Thus, the Company to effectively address the year 2000 issue could have a material
effect on its results of operations and its ability to conduct its
business.

    The Company's systems and operations with respect to the year
2000 issue may also be affected by other entities with which the
Company transacts business.  The Company is currentlypresently unable to determine the potential
adverse consequences, if any, that could result from each such
entities' failure to effectively address the year 2000 issue.  As
of September 30, 1998, the assessment phase, as it relates to the
Company's review of its inventory items, has been substantially
completed.

    The remediation, testing and implementation phases of the
Company's year 2000 plan are currently in various stages of
completion.  The remediation phase includes replacements,
modifications and/or upgrades necessary for year 2000 compliance
that were identified in the assessment phase.  As of September 30,
1998, the remediation phase at the oil and natural gas production
business is substantially complete; at the electric, natural gas
distribution and natural gas transmission businesses is more than
50 percent complete; and at the construction materials and mining
business is in the beginning stages of completion.  The testing
phase involves testing systems to confirm year 2000 readiness.  As
of September 30, 1998, the testing phase at the oil and natural gas
production business is substantially complete; at the electric,
natural gas distribution and natural gas transmission businesses is
over 25 percent complete; and at the construction materials and
mining business is in the beginning stages of completion.  The
implementation phase is the process of moving a year 2000 compliant
item into production status.  As of September 30, 1998, the
implementation phase at the oil and natural production business is
substantially complete; at the electric, natural gas distribution
and natural gas transmission businesses is more than 50 percent
complete; and at the construction materials and mining business is
in the beginning stages of completion.  The Company has established
a target date of  October 1, 1999 to complete the remediation,
testing and implementation phases.

Costs --

    The estimated incremental cost to the Company of the year 2000
issue is approximately $1 million to $3 million during the 1998
through 2000 time periods.  As of September 30, 1998, the Company
has incurred incremental costs of less than $100,000.  These costs
are being funded through cash flows from operations.  The Company's
current estimate of costs of the year 2000 issue is based on the
facts and circumstances existing at this time, which were derived
utilizing numerous assumptions of future events.

Risks --

    The failure to correct a material year 2000 problem, including
failures on the part of third parties, could result in a temporary
interruption in, or failure of, certain critical business
operations, including electric distribution, generation and
transmission; natural gas distribution, transmission, storage and
gathering; energy marketing; mining and marketing of coal,
aggregates and related construction materials; oil and natural gas
exploration, production, and development; and utility line
construction and repair services.   Although the Company believes
the project will be completed by October 1, 1999, unforeseen and
other factors could cause delays in the project, the results of
which could have a material effect on the results of operations and
the Company's ability to conduct its business.

Contingency Planning --

    Due to the general uncertainty inherent in the year 2000 issue,
including the uncertainty of the year 2000 readiness of third
parties, the Company anticipates having contingency plans in place
by October 1, 1999 designed to address the Company's critical
business operations as previously discussed.

    Other corporate net capital expenditures for 1998 are estimated
at $18$18.9 million, including those expenditures required for the
acquisition of Pouk & Steinle, Inc., Harp Line and Harp Engineering,
and for routine equipment maintenance and replacements.  These
capital expenditures are anticipated to be met through internal
sources, short-term lines of credit aggregating $4.8 million, $739,000$2.6
million of which was outstanding at JuneSeptember 30, 1998, and the
issuance of the Company's equity securities.

    The estimated 1998 net capital expenditures set forth above 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
