              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 JUNE 30, 2000
                                  (UNAUDITED)

Note A - General

The accompanying unaudited Condensed Consolidated Financial Statements have been
prepared in accordance with generally accepted accounting principles for interim
financial reporting and Securities and Exchange Commission regulations, but are
subject to any year-end adjustments which may be necessary.  In the opinion of
management, all adjustments (consisting of normal recurring accruals) considered
necessary for a fair presentation have been included.  Results of operations for
the periods ended June 30, 2000 are not necessarily indicative of results to be
expected for the year ending December 31, 2000.  Arch Coal, Inc. (the "Company")
operates one reportable segment: the production of steam and metallurgical coal
from surface and deep mines throughout the United States, for sale to utility,
industrial and export markets.  The Company's mines are located in the central
Appalachian and western regions of the United States.  All subsidiaries (except
as noted below) are wholly owned.  Significant intercompany transactions and
accounts have been eliminated in consolidation.

Arch Western Resources, LLC ("Arch Western"), a subsidiary of the Company, is
99% owned by the Company and 1% owned by Atlantic Richfield Company ("ARCO"),
which merged with a subsidiary of BP Amoco on April 18, 2000.  The principal
operating units of Arch Western are Thunder Basin Coal Company, L.L.C., owned
100% by Arch Western, which operates two coal mines in the Southern Powder River
Basin in Wyoming; Mountain Coal Company, L.L.C., owned 100% by Arch Western,
which operates one coal mine in Colorado; Canyon Fuel Company, LLC ("Canyon
Fuel"), 65% owned by Arch Western and 35% by ITOCHU Coal International Inc., a
subsidiary of ITOCHU Corporation, which operates three coal mines in Utah; and
Arch of Wyoming, LLC, owned 100% by Arch Western, which operates two coal mines
in the Hanna Basin of Wyoming.

The Company's 65% ownership of Canyon Fuel is accounted for on the equity method
in the Condensed Consolidated Financial Statements as a result of certain super-
majority voting rights in the joint venture agreement.  Income from Canyon Fuel
is reflected in the Condensed Consolidated Statements of Operations as income
from equity investment (see additional discussion in "Investment in Canyon Fuel"
in Note C).

Note B - Change in Accounting Method

Through December 31, 1998, plant and equipment have principally been depreciated
on the straight-line method over the estimated useful lives of the assets, which
range from three to twenty years.  Effective January 1, 1999, depreciation on
the Company's preparation plants and loadouts was computed using the units-of-
production method, which is based upon units produced, subject to a minimum
level of depreciation.  These assets are usage-based assets and their economic
lives are typically based and measured on coal throughput.  The Company believes
the units-of-production method is preferable to the method previously used
because the new method recognizes that depreciation of this equipment is related
substantially to physical wear due to usage and also to the passage of time.
This method, therefore, more appropriately matches production costs over the
lives of the preparation plants and loadouts with coal sales revenue and results
in a more accurate allocation of the cost of the physical assets to the periods
in which the assets are consumed.  The cumulative effect of applying the new
method for years prior to 1999 is an increase to income of $3.8 million net-of-
tax ($6.3 million pre-tax) reported as a cumulative effect of accounting change
in the Condensed Consolidated Statement of Operations for the six months ended
June 30, 1999.

Note C - Investment in Canyon Fuel

The following table presents unaudited summarized financial information for
Canyon Fuel which, as part of the Company's June 1, 1998 acquisition of ARCO's
coal operations (the "Arch Western transaction"), is accounted for on the equity
method:

The Company's income (loss) from its equity investment in Canyon Fuel represents
65% of Canyon Fuel's net income after adjusting for the effect of its investment
in Canyon Fuel.  The Company's investment in Canyon Fuel reflects purchase
adjustments primarily related to the reduction in amounts assigned to sales
contracts, mineral reserves and other property, plant and equipment.

In connection with the Arch Western transaction, the Company entered into two
five-year credit facilities: a $675 million non-amortizing term loan in the name
of Arch Western, the entity owning the right to the coal reserves and operating
assets acquired in the Arch Western transaction, and a $900 million credit
facility in the name of the Company, including a $300 million fully amortizing
term loan and a $600 million revolver.  Borrowings under these credit facilities
were used to finance the acquisition of ARCO's Colorado and Utah coal
operations, to pay related fees and expenses, to refinance existing corporate
debt and for general corporate purposes.  Borrowings under the

                                       5


Arch Western credit facility were used to fund a portion of a $700 million cash
distribution by Arch Western to ARCO, which distribution occurred simultaneously
with ARCO's contribution of its Wyoming coal operations and certain other assets
to Arch Western and which distribution represented part of the purchase price
for the ARCO coal operations. The $675 million term loan is secured by Arch
Western's membership interests in its subsidiaries. The Arch Western credit
facility is not guaranteed by the Company. The rate of interest on the
borrowings under the agreements is, at the Company's option, the PNC Bank base
rate or a rate based on LIBOR. At June 30, 2000, the Company's debt is
approximately 84% of capital employed.

Terms of the Company's credit facilities and leases contain financial and other
restrictive covenants that limit the ability of the Company to, among other
things, pay dividends, effect acquisitions or dispositions and borrow additional
funds and require the Company to, among other things, maintain various financial
ratios and comply with various other financial covenants.  Failure by the
Company to comply with such covenants could result in an event of default which,
if not cured or waived, could have a material adverse effect on the Company.  At
December 31, 1999, as a result of the effect of the write-down of impaired
assets and other restructuring costs incurred during 1999, the Company did not
comply with certain of these restrictive covenant requirements, for which the
Company received an amendment on January 21, 2000.  These amendments resulted
in, among other things, a one time payment of $1.8 million and an increase in
the interest rate of .375% associated with the Company's term loan and the $600
million revolver.  In addition, the amendments required the pledging of assets
to collateralize the term loan and the $600 million revolver by May 17, 2000.
The assets, which were pledged by such date, include equity interests in wholly
owned entities, certain real property interests, accounts receivable and
inventory of the Company and such wholly owned entities.

The Company enters into interest-rate swap and collar agreements to modify the
interest-rate characteristics of the Company's outstanding debt.  At June 30,
2000, the Company had interest-rate swap and collar agreements having a total
notional value of $782.5 million.  These swap and collar agreements were used to
convert variable-rate debt to fixed-rate debt.  Under these swap and collar
agreements, the Company pays a weighted-average fixed-rate of 5.74% (before the
credit spread over LIBOR) and is receiving a weighted-average variable-rate
based upon 30-day and 90-day LIBOR.  At June 30, 2000, the remaining term of the
swap and collar agreements ranged from 26 to 60 months.

Note F - Stockholder Rights Plan

On March 3, 2000, the Board of Directors adopted a stockholder rights plan under
which preferred share purchase rights were distributed as a dividend to the
Company's stockholders of record on March 20, 2000.  The rights are exercisable
only if a person or group acquires 20% or more of the Company's Common Stock (an
"Acquiring Person") or announces a tender or exchange offer the consummation of
which would result in ownership by a person or group of 20% or more of the
Company's Common Stock.  Each right entitles the holder to buy one one-hundredth
of a share of a series of junior participating preferred stock at an exercise
price of $42, or in certain circumstances allows the holder (except for the
Acquiring Person) to purchase the Company's Common Stock or voting stock of the
Acquiring Person at a discount.  At its option, the Board of Directors may allow
some or all holders (except for the Acquiring Person) to exchange their rights
for Company Common Stock.  The rights will expire on March 20, 2010, subject to
earlier redemption or exchange by the Company as described in the plan.

Note G - Contingencies

The Company is a party to numerous claims and lawsuits with respect to various
matters.  The Company provides for costs related to contingencies, including
environmental matters, when a loss is probable and the amount is reasonably
determinable.  The Company estimates that its probable aggregate loss as a
result of such claims as of June 30, 2000 is $4.6 million (included in other
noncurrent liabilities), of which $2.5 million relates to a settlement with the
U.S. Department of the Interior associated with the 1996 impoundment failure at
Lone Mountain.  The Company estimates that its reasonably possible aggregate
losses from all material litigation that is currently pending could be as much
as $.5 million (before taxes) in excess of the probable loss previously
recognized.  After conferring with counsel, it is the opinion of management that
the ultimate resolution of these claims, to the extent not previously provided
for, will not have a material adverse effect on the consolidated financial
position, results of operations or liquidity of the Company.

Note H - Changes in Estimates and Other Non-Recurring Revenues and Expenses

The Company's operating results for the three and six months ended June 30, 2000
reflect a $12.0 million partial insurance payment received as part of the
Company's coverage under its property and business interruption insurance
policy.  The payment offsets a portion of the loss incurred at the West Elk mine
in Gunnison County, Colorado which was idled from January 28, 2000 to July 12,
2000 following the detection of combustion related gases there.  As a result of
recent permit revisions at its idle mine properties in Illinois, the Company
reviewed and reduced its reclamation liability at Arch of Illinois by $7.8
million.  In addition, the IRS issued a notice during the current quarter
outlining the procedures for obtaining tax refunds on certain excise taxes paid
by the industry on export sales tonnage.  The notice is a result of a 1998
federal district court decision that found such taxes to be unconstitutional.
The Company recorded $12.7 million of income related to these excise tax
recoveries.

The Company's operating results for the six months ended June 30, 1999 reflect a
charge of $6.5 million related to the planned temporary shut down of its Dal-Tex
mine in Logan County, West Virginia on July 23, 1999.  The charge consisted
principally of severance costs, obligations for non-cancelable lease payments
and a change in the reclamation liability due to the temporary shut down.  The
shut down was due to a delay in obtaining mining permits resulting from legal
action in the U.S. District Court for the Southern District of West Virginia
(for a discussion of the legal action, see the "Contingencies - Legal
Contingencies - Dal-Tex Litigation" section of Management's Discussion and
Analysis of Financial Condition and Results of Operations in this report).

During 1999, the Company recorded pre-tax charges totaling $23.1 million
(including the $6.5 million charge discussed above) related to (i) the
restructuring of its administrative workforce; (ii) the closure of its Dal-Tex
mine in West Virginia due to permitting problems; and (iii) the closure of
several small mines in Kentucky (Coal-Mac) and the one remaining underground
mine in Illinois (Arch of Illinois) due to depressed coal prices, caused in part
by increased competition from western coal mines.  The following are the
components of severance and other exit costs included in the restructuring
charge along with related activity:




                                                                         Utilized      Utilized During

Except for the charge related to depreciation acceleration, all of the 1999
restructuring charge will require the Company to use cash.  Also, the Company
expects to utilize the balance of the amounts reserved for employee cost during
the remainder of 2000, while obligations for non-cancelable lease payments and
reclamation liabilities will be utilized in future periods as lease payments are
made and reclamation procedures are performed.

Note I - Sale and Leaseback

On June 30, 2000, the Company sold several shovels and several continuous miners
for $14.9 million and leased back the equipment under operating leases.  The
proceeds of the sales were used to pay down debt and for general corporate
purposes.  The shovels have been leased over a period of 5 years while the
continuous miners have been leased with terms ranging from 2 to 5 years.  The
leases contain renewal options at lease termination and purchase options at
amounts approximating fair value at lease termination. The gain on the sale and
leaseback of $1.5 million was deferred and is being amortized over the base of
the lease as a reduction of lease expense.  Future non-cancelable rental
payments under the leases are expected to be approximately $1.7 million for the
remainder of 2000, $3.4 million in 2001, $3.2 million in 2002, $3.0 million in
2003, $3.0 million in 2004 and $1.5 million in 2005.

                                       7


On January 29, 1998, the Company sold mining equipment for approximately $74.2
million and leased back the equipment under an operating lease with a term of
three years.  This included the sale and leaseback of equipment purchased under
an existing operating lease that expired on the same day.  The proceeds of the
sale were used to purchase the equipment under the expired lease for $28.3
million and to pay down debt.  At the end of the lease term, the Company had the
option to renew the lease for two additional one-year periods or purchase the
equipment.  Alternatively, the equipment could be sold to a third party.  In the
event of such a sale, the Company was required to make a payment to the lessor
in the event, and to the extent, that the sale proceeds were below a certain
threshold.  The gain on the sale and leaseback of $10.7 million was deferred and
was amortized over the base of the lease as a reduction of lease expense.
Effective February 4, 2000, the Company purchased for $10.3 million several
pieces of equipment under lease that were included in this transaction and
transferred them to the Company's Wyoming operations.  A pro-rata portion of the
deferred gain, $.3 million, was offset against the cost of the assets.  On May
17, 2000, the Company purchased the remaining assets under the lease for $34.7
million, which resulted in the termination of this lease.  The remaining
deferred gain of $1.2 million was offset against the cost of the assets.

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

This amendment to quarterly report on Form 10-Q/A contains forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933 and
Section 21E of the Securities Exchange Act of 1934, including statements in the
"Outlook" and "Liquidity and Capital Resources" sections below.  Words such as
"anticipates," "believes," "estimates," "expects," "is likely," "predicts,"
"may" and variations of such words and similar expressions are intended to
identify such forward-looking statements.  Although the Company believes that
its expectations are based on reasonable assumptions, it cannot assure that the
expectations contained in such statements will be achieved.  Important factors
which could cause actual results to differ materially from those contained in
such statements are discussed in the "Contingencies" and "Certain Trends and
Uncertainties" sections below.

RESULTS OF OPERATIONS

Quarter Ended June 30, 2000 Compared
 to Quarter Ended June 30, 1999

The Company incurred a net loss of $2.1 million for the quarter ended June 30,
2000 compared to net income of $2.5 million for the quarter ended June 30, 1999.
Results for the quarter were adversely impacted by the continued

                                       8


idling of the West Elk mine in Gunnison County, Colorado. The mine was idled on
January 28, 2000, following the detection of combustion gases in a portion of
the mine. During the current quarter, the mine had no coal sales and incurred an
operating loss of $22.3 million (excluding insurance recoveries) compared to
$27.2 million of coal sales and $4.8 million of operating income during the
quarter ended June 30, 1999. Offsetting a portion of the loss at the West Elk
mine was a $12.0 million pre-tax partial insurance payment received as part of
the Company's coverage under its property and business interruption insurance
policy. Also, as a result of recent permit revisions at its idle mine properties
in Illinois, the Company reviewed and reduced its reclamation liability at that
location by $7.8 million during the quarter. In addition, the IRS issued a
notice during the current quarter outlining the procedures for obtaining tax
refunds on certain excise taxes paid by the industry on export sales tonnage.
The notice is a result of a 1998 federal district court decision that found such
taxes to be unconstitutional. The Company recorded $12.7 million of pre-tax
income related to these excise tax recoveries.

Total revenues for the quarter ended June 30, 2000 decreased 13% from the
quarter ended June 30, 1999 as a result of several factors.  Those factors
include reduced sales at the Company's West Elk mine as a result of the
continued idling described above.  In addition, the Company closed its Dal-Tex,
Wylo and Arch of Illinois operations and two surface mines in Kentucky during
1999.

The Company idled the Dal-Tex operation on July 23, 1999 due to a delay in
obtaining new mining permits which resulted from legal action in the U.S.
District Court for the Southern District of West Virginia (see additional
discussion in the "Contingencies - Legal Contingencies - Dal-Tex Litigation"
section of this report).  The Wylo operation ceased production in December 1999
due to the depletion of its recoverable reserves.  The Arch of Illinois
operation was closed due to a lack of demand for the mine's high-sulfur coal.
Demand for high-sulfur coal has declined rapidly as a result of the stringent
Clean Air Act requirements that are driving a shift to low-sulfur coal.  The two
small surface mines in Kentucky are affiliated with the Coal-Mac operation and
were closed as a result of their cost structures not being competitive in the
current market.  These factors were partially offset by increased production and
sales at the Company's Black Thunder mine in Wyoming and increased brokered coal
sales during the quarter when compared to the quarter ended June 30, 1999.  On a
per-ton-sold basis, the Company's average selling price of $12.98 decreased
$1.10 from the same period in the prior year primarily as a result of the
continuing expected shift of coal sales from the Company's eastern operations to
its western operations.  Western coal has a significantly lower average sales
price than that provided from the Company's eastern coal operations, but is also
significantly less costly to mine.

Excluding the period over period decrease in income from operations resulting
from the temporary idling of the West Elk mine, the partial insurance payment,
the reclamation liability adjustment at Arch of Illinois and the excise tax
recoveries (all described above), income from operations decreased $6.2 million
for the quarter ended June 30, 2000 when compared to the same period in the
prior year.  The decrease is attributable to the continuing difficult market
conditions that prevailed in U.S. coal markets during the quarter along with
increased fuel costs that were up over $1.0 million per month compared to the
same period last year resulting from higher diesel fuel and oil prices.  In
addition, income from operations also declined at the Company's Mingo Logan
longwall operation (Mountaineer Mine) where, despite another strong second
quarter and the contribution of $9.0 million of income from operations, results
were below the $11.6 million of income from operations from the second quarter
of 1999.  The decrease was primarily caused by continuing depressed coal prices,
generally less favorable mining conditions and increased mine development
expenses associated with the start-up of the Alma seam operation.  The
Mountaineer Mine contributed 13% and 12% of the Company's coal sales revenues in
the quarter ended June 30, 2000 and 1999, respectively.   Lone Mountain also
experienced reduced income from operations caused by adverse mining conditions
which reduced production at the mine and also caused increased mining expenses.
Partially offsetting the decrease in income from operations was ongoing improved
performance at several other of the Company's mines caused in part by the
continued Company focus on reducing costs and improving productivity, as well as
reduced costs in the current quarter resulting from the closure of the Dal-Tex
operation in July 1999.  The Dal-Tex operation incurred production shortfalls,
deterioration of mining conditions and resulting lower income contributions
prior to its closing on July 23, 1999.  Other factors that affected quarter to
quarter comparisons were several sales of surplus land which resulted in a gain
of $3.5 million during the current quarter.  During the quarter ended June 30,
1999 the Company sold a dragline at the Arch of Illinois operation resulting in
a gain of $2.5 million and also had settlements with two suppliers that added
$2.5 million to the prior quarter's results.

Selling, general and administrative expenses increased $1.0 million from the
second quarter of 1999.  The increase

                                       9


is attributable to higher legal and consulting expenses partially offset by cost
savings resulting from the restructuring of the Company's administrative
workforce that occurred during the fourth quarter of 1999.

The Company's effective tax rate is sensitive to changes in annual profitability
and percentage depletion.  During the fourth quarter of 1999, the Company
determined that as it relates to future income taxes, the Company does not
anticipate recognizing all of its alternative minimum tax credit carry-forwards
in the future and expects to recognize part of the benefit of its deferred tax
asset at the alternative minimum tax rate of approximately 24%.

Adjusted EBITDA (income from operations before the effect of changes in
accounting principles and extraordinary items; unusual items; net interest
expense; income taxes; depreciation, depletion and amortization of Arch Coal,
its subsidiaries and its ownership percentage in its equity investments) was
$80.8 million for the current quarter compared to $88.2 million for the second
quarter of 1999.  The decrease in adjusted EBITDA was primarily attributable to
the temporary idling of the West Elk mine partially offset by improved
performance at the Company's Black Thunder mine.  Adjusted EBITDA should not be
considered in isolation or as an alternative to net income, operating income or
cash flows from operations or as a measure of a company's profitability,
liquidity or performance under U.S. generally accepted accounting principles.

Six Months Ended June 30, 2000 Compared
  to Six Months Ended June 30, 1999

The Company incurred a net loss of $17.2 million for the six months ended June
30, 2000 compared to net income of $3.9 million for the six months ended June
30, 1999.  Results for the six months ended June 30, 2000 were adversely
impacted by the temporary idling of the West Elk mine in Gunnison County,
Colorado.  The mine was idled on January 28, 2000, following the detection of
combustion gases in a portion of the mine.  During the six months ended June 30,
2000, the mine contributed $8.9 million of coal sales and incurred an operating
loss of $34.1 million (excluding insurance recoveries) compared to $54.5 million
of coal sales and $6.3 million of operating income during the six months ended
June 30, 1999.  Offsetting a portion of the loss at the West Elk mine was a
$12.0 million pre-tax partial insurance payment received as part of the
Company's coverage under its property and business interruption insurance
policy.  Also, as a result of recent permit revisions at its idle mine
properties in Illinois, the Company reviewed and reduced its reclamation
liability at that location by $7.8 million during the current period.  In
addition, the IRS issued a notice during the current period outlining the
procedures for obtaining tax refunds on certain excise taxes paid by the
industry on export sales tonnage.  The notice is a result of a 1998 federal
district court decision that found such taxes to be unconstitutional.  The
Company recorded $12.7 million of pre-tax income related to these excise tax
recoveries.

Total revenues for the six months ended June 30, 2000 decreased 14% from the
same period in the prior year as a result of several factors.  Those factors
include reduced sales at the Company's West Elk mine as a result of the idling
described above.  In addition, the Company closed its Dal-Tex, Wylo and Arch of
Illinois operations and two surface mines in Kentucky during 1999.

The Company idled the Dal-Tex operation on July 23, 1999 due to a delay in
obtaining new mining permits which resulted from legal action in the U.S.
District Court for the Southern District of West Virginia (see additional
discussion in the "Contingencies - Legal Contingencies - Dal-Tex Litigation"
section of this report).  The Wylo operation ceased production in December 1999
due to the depletion of its recoverable reserves.  The Arch of Illinois
operation was closed due to a lack of demand for the mine's high-sulfur coal.
Demand for high-sulfur coal has declined rapidly as a result of the stringent
Clean Air Act requirements that are driving a shift to low-sulfur coal.  The two
small surface mines in Kentucky are affiliated with the Coal-Mac operation and
were closed as a result of its cost structure not being competitive in the
current market.  These factors were partially offset by increased production and
sales at the Company's Black Thunder mine in Wyoming when compared to the six
months ended June 30, 1999.  On a per-ton-sold basis, the Company's average
selling price of $12.68 decreased $1.69 from the same period in the prior year
primarily as a result of the continuing increase in coal sales from the
Company's western operations.  Western coal has a significantly lower average
sales price than that provided from the Company's eastern coal operations, but
is also significantly less costly to mine.

Excluding the decrease in income from operations resulting from the temporary
idling of the West Elk mine from the prior year, the partial insurance payment,
the reclamation liability adjustment at Arch of Illinois and the excise

                                       10


tax recoveries (all described above), income from operations decreased $3.9
million for the six months ended June 30, 2000 when compared to the same period
in the prior year. The decrease is attributable to the continuing difficult
market conditions that prevailed in U.S. coal markets during the period along
with increased fuel costs that were up over $1.0 million per month compared to
the same period last year resulting from higher diesel fuel and oil prices. In
addition, income from operations also declined at the Company's Mingo Logan
longwall operation (Mountaineer Mine) where, despite another strong six months
and the contribution of $22.1 million of income from operations, results were
below the $28.0 million of income from operations from the six months ended June
30, 1999. The decrease was primarily caused by continuing depressed coal prices,
generally less favorable mining conditions and increased mine development
expenses associated with the start-up of the Alma seam operation. The
Mountaineer Mine contributed 13% and 12% of the Company's coal sales revenue in
the six months ended June 30, 2000 and 1999, respectively. Partially offsetting
the decrease in income from operations was ongoing improved performance at
several other of the Company's mines caused in part by the continued Company
focus on reducing costs and improving productivity and reduced costs in the
current period resulting from the closure of the Dal-Tex operation in July 1999.
The Dal-Tex complex incurred production shortfalls, deterioration of mining
conditions and resulting lower income contributions prior to its closing on July
23, 1999. As a result of the closing, the Company recorded a charge of $6.5
million during the first quarter of 1999, comprised principally of severance
costs, obligations for non-cancelable lease payments and a change in the
reclamation liability due to the closure. Other factors that affected period to
period comparisons were several sales of surplus land which resulted in a gain
of $4.1 million during the current period. During the six months ended June 30,
1999 the Company sold a dragline at the Arch of Illinois operation resulting in
a gain of $2.5 million and also had settlements with two suppliers that added
$4.0 million to the prior period's results.

Selling, general and administrative expenses decreased $1.7 million from the six
months ended June 30, 1999.  The decrease is attributable to cost savings
resulting from the restructuring of the Company's administrative workforce that
occurred during the fourth quarter of 1999.  The decrease is partially offset by
higher legal and consulting expenses incurred during the second quarter of 2000.

The Company's effective tax rate is sensitive to changes in annual profitability
and percentage depletion.  During the fourth quarter of 1999, the Company
determined that as it relates to future income taxes, the Company does not
anticipate recognizing all of its alternative minimum tax credit carry-forwards
in the future and expects to recognize part of the benefit of its deferred tax
asset at the alternative minimum tax rate of approximately 24%.

Adjusted EBITDA (income from operations before the effect of changes in
accounting principles and extraordinary items; unusual items; net interest
expense; income taxes; depreciation, depletion and amortization of Arch Coal,
its subsidiaries and its ownership percentage in its equity investments) was
$144.4 million for the six months ended June 30, 2000 compared to $174.2 million
for the same period in the prior year.  The decrease in adjusted EBITDA was
primarily attributable to the temporary idling of the West Elk mine partially
offset by improved performance at the Company's Black Thunder mine.

OUTLOOK

West Elk Mine.  On July 12, 2000, the Company resumed longwall production at its
West Elk underground mine in Gunnison County, Colorado.  West Elk had been idle
since January 28, 2000, following the detection of combustion-related gases in a
portion of the mine.  The Company expects West Elk to return to normal levels of
production in the near term.  West Elk incurred between $4 million and $6
million per month in after-tax losses while the mine was idled and the Company
engaged in efforts to suppress the combustion.  Additional fire-related costs
will continue to be incurred during the balance of the year and into 2001 as the
Company reclaims drilling sites and roads and eventually dismantles pumping
equipment.  During June, the Company recognized a $12.0 million pre-tax partial
insurance payment that covered a portion of the losses incurred at West Elk
during the quarter.  The Company expects to receive additional insurance
payments under its property and business interruption policy.  There can be no
assurance of additional recovery, however, until the claim is resolved with the
insurance carrier.

West Virginia Operations.  On October 20, 1999, the U.S. District Court for the
Southern District of West Virginia permanently enjoined the West Virginia
Division of Environmental Protection (the "West Virginia DEP") from issuing
permits that authorize the construction of valley fills as part of coal mining
operations.  The West Virginia DEP complied with the injunction by issuing an
order banning the issuance of nearly all new permits for valley fills

                                       11


and prohibiting the further advancement of nearly all existing fills. On October
29, 1999, the district court granted a stay of its injunction, pending the
outcome of an appeal of the court's decision filed by the West Virginia DEP with
the U.S. Court of Appeals for the Fourth Circuit. The West Virginia DEP
rescinded its order in response to the stay granted by the court. It is
impossible to predict the outcome of the West Virginia DEP's appeal to the
Fourth Circuit. If, however, the district court's ruling is not overturned or if
a legislative or other solution is not achieved, then the ability of the Company
and other coal producers to mine coal in West Virginia would be seriously
compromised.

The injunction discussed above was entered as part of the litigation that caused
the delay in obtaining mining permits for the Company's Dal-Tex operation (see
additional discussion of this litigation in the "Contingencies - Legal
Contingencies - Dal-Tex Litigation" section of this report).  As a result of
such delay, the Company idled its Dal-Tex mining operation on July 23, 1999.
The Company remains hopeful that it can reopen the Dal-Tex operation after all
necessary permits are obtained, which is not expected to occur until mid-2001 at
the earliest.  Reopening the mine is, however, contingent upon the district
court's injunction being overturned or a legislative or other solution being
achieved, as well as then-existing market conditions.

Coal Markets.  Although the Company continues to be adversely affected by weak
market conditions, developments that may translate into improved market
conditions for coal are continuing.  Electric generation continues to increase,
up approximately 4% compared to 1999.  Also, coal's share of the electric
generation market is up approximately 1% compared to 1999.  The average price of
natural gas for the summer to date is roughly double its average price in 1999.
No nuclear plants are planned or are being built.  Hydro conditions are weaker
than normal due to dry conditions.  Also, in recent weeks, quoted and spot
prices appear to be rising.  The Company is hopeful that the movement in such
prices is an indication that a stronger coal market will start to materialize
because of these and other developments.  However, because most of the Company's
production is already committed and priced for the current year, the Company
expects its performance for the remainder of the year to reflect the current
market weakness.

The Company continues to take steps to match its production levels to market
needs.  The Company has substantially reduced production at its Coal Creek
surface mine in Campbell County, Wyoming and plans to idle the mine in the third
quarter.  The planned idling is not expected to have a material impact on the
Company's revenues or results of operations.  The Company also plans to maintain
a production level of approximately 60 million tons from its Black Thunder mine
near Gillette, Wyoming.  Demand for Powder River Basin coal has more than
doubled in the past decade.  The Company is optimistic that the continuing
increase in demand, coupled with its recent actions, will be reflected by
stronger prices for PRB coal in the future.

Low-Sulfur Coal Producer.  The Company continues to believe that it is uniquely
positioned to capitalize on the continuing growth in demand for electricity.
With Phase II of the Clean Air Act in effect, compliance coal has captured a
growing share of U.S. coal demand and commands a higher price than higher sulfur
coals in the marketplace.  Compliance coal is coal that meets the requirements
of Phase II of the Clean Air Act without the use of expensive scrubbing
technology.  All of Arch's western coal production and approximately half of its
eastern production is compliance quality.

Chief Financial Objectives.  The Company continues to focus on realizing the
substantial potential of its assets and maximizing shareholder value by making
decisions based upon its five chief financial objectives: (i) aggressively
paying down debt, (ii) further strengthening cash generation, (iii) improving
earnings, (iv) increasing productivity and (v) reducing costs throughout the
Company.

Despite making the second of five annual payments of $31.6 million for the
Thundercloud federal reserve lease, which was acquired in 1998, lower cash
generation and increased expenditures related to the idling of the West Elk mine
and a net payment of $31.6 million to purchase assets out of an operating lease,
the Company repaid $7.4 million of debt in the first half of the year and
anticipates continuing to make substantial progress toward reducing debt in the
second half of 2000.

The Company is aggressively pursuing cost savings.  In addition to the
corporate-wide restructuring in late 1999 that the Company believes will likely
result in a reduction in operating costs for the current and future years, the
Company recently initiated a cost reduction effort targeting key cost drivers at
each of its captive mines.  The

                                       12


Company is also exploring Internet-based solutions that could reduce costs,
especially in the procurement area.

Registration of Ashland Inc.'s Remaining Shares.  On August 3, 2000, the Company
received a written notice from Ashland Inc. ("Ashland") pursuant to which
Ashland exercised its demand registration rights under the Registration Rights
Agreement, dated April 4, 1997, by and among the Company, Ashland, Carboex
International, Limited (now Carboex, S.A.) and the certain Hunt entities listed
on Schedules I and II thereto.  Ashland has requested that its remaining
4,756,968 shares be disposed of by means of an underwritten offering.  Ashland
has selected Merrill Lynch & Co. as its managing underwriter for the sale of the
shares.

LIQUIDITY AND CAPITAL RESOURCES

The following is a summary of cash provided by or used in each of the indicated
types of activities during the six months ended June 30, 2000 and 1999:



                                                             2000                     1999
                                                      -------------------      ------------------
                                                                     (in thousands)
                                                                         
   Cash provided by (used in):
      Operating activities                                 $  97,194               $ 153,450
      Investing activities                                  (100,133)                (41,366)
      Financing activities                                     1,538                (122,458)


Cash provided by operating activities decreased in the six months ended June 30,
2000 compared to the same period in 1999 due to a decrease in cash provided from
equity investments and reduced cash from coal sales along with increased costs
resulting from the temporary idling of the West Elk mine.  These were partially
offset by increased receivable collections and an increase in accounts payable
and accrued expenses in the current period when compared to the prior year's
period.  The decrease in cash provided from equity investments results primarily
from the amendment in the prior year of a coal supply agreement with the
Intermountain Power Agency, which was a significant portion of the $59.8 million
cash distribution from Canyon Fuel.

Cash used in investing activities increased in the six months ended June 30,
2000 compared to the same period in 1999 primarily as a result of the Company
making the second of five annual payments under the Thundercloud federal lease
which is part of the Black Thunder mine in Wyoming.  The first payment was due
at the time of the acquisition of the lease in 1998.  The remaining three
payments are due each January of the years 2001 through 2003.  In addition,
during the first six months ended June 30, 2000, the Company purchased all
remaining assets under a 1998 sale and leaseback arrangement for $45.0 million.
Period-over-period comparisons are also affected by the amendment of another
coal supply agreement during 1999.  The amendment changed the contract terms
from above-market to market-based pricing.  As a result of the amendment, the
Company received proceeds of $14.1 million from the customer (net of royalty and
tax obligations) during the first quarter of 1999.

Cash provided by financing activities reflects reduced debt payments in the
current period compared to the same period in the prior year.  In addition,
during the second quarter of 2000, the Company entered into a sale and leaseback
of certain equipment which resulted in net proceeds of $13.4 million.  Dividend
payments have decreased $4.4 million in the current period as compared to the
same period in the prior year, resulting from a decrease in shares outstanding,
and a reduction in the quarterly dividend from 11.5 cents per share to 5.75
cents per share.  The dividend reduction is attributable to the Company's goal
to aggressively pay down debt.

The Company periodically establishes uncommitted lines of credit with banks.
These agreements generally provide for short-term borrowings at market rates.
At June 30, 2000, there were $20 million of such agreements in effect, of which
none were outstanding.

The Company is exposed to market risk associated with interest rates.  At June
30, 2000, debt included $1.168 billion of floating-rate debt, which is, at the
Company's option, the PNC Bank base rate or a rate based on LIBOR and current
market rates for bank lines of credit.  To manage these exposures, the Company
enters into interest-rate swap agreements to modify the interest-rate
characteristics of outstanding Company debt.  At June 30, 2000, the Company had
interest-rate swap agreements having a total notional value of $782.5 million.
These swap agreements are used to convert variable-rate debt to fixed-rate debt.
Under these swap agreements, the Company

                                       13


pays a weighted average fixed rate of 5.74% (before the credit spread over
LIBOR) and receives a weighted average variable rate based upon 30-day and 90-
day LIBOR. The Company accrues amounts to be paid or received under interest-
rate swap agreements over the lives of the agreements. Such amounts are
recognized as adjustments to interest expense over the lives of agreements,
thereby adjusting the effective interest rate on the Company's debt. The fair
value of the swap agreements are not recognized in the financial statements.
Gains and losses on terminations of interest-rate swap agreements are deferred
on the balance sheet (in other long-term liabilities) and amortized as an
adjustment to interest expense over the remaining term of the terminated swap
agreement. The remaining terms of the swap agreements at June 30, 2000 ranged
from 26 to 60 months. All instruments are entered into for other than trading
purposes.

The discussion below presents the sensitivity of the market value of the
Company's financial instruments to selected changes in market rates and prices.
The range of changes reflects the Company's view of changes that are reasonably
possible over a one-year period.  Market values are the present value of
projected future cash flows based on the market rates and prices chosen.  The
major accounting policies for these instruments are described in Note 1 to the
consolidated financial statements of the Company as of and for the year ended
December 31, 1999 as filed on Form 10-K with the Securities and Exchange
Commission.

Changes in interest rates have different impacts on the fixed-rate and variable-
rate portions of the Company's debt portfolio.  A change in interest rates on
the fixed portion of the debt portfolio impacts the net financial instrument
position but has no impact on interest incurred or cash flows.  A change in
interest rates on the variable portion of the debt portfolio impacts the
interest incurred and cash flows but does not impact the net financial
instrument position.

The sensitivity analysis related to the fixed portion of the Company's debt
portfolio assumes an instantaneous 100-basis-point move in interest rates from
their levels at June 30, 2000 with all other variables held constant.  A 100-
basis-point decrease in market interest rates would result in an increase in the
net financial instrument position of the fixed portion of debt of $19.7 million
at June 30, 2000.  Based on the variable-rate debt included in the Company's
debt portfolio as of June 30, 2000, after considering the effect of the swap
agreements, a 100-basis-point increase in interest rates would result in an
annualized additional $3.9 million of interest expense incurred based on June
30, 2000 debt levels.

CONTINGENCIES

Reclamation

The federal Surface Mining Control and Reclamation Act of 1977 ("SMCRA") and
similar state statutes require that mine property be restored in accordance with
specified standards and an approved reclamation plan.  The Company accrues for
the costs of final mine closure reclamation over the estimated useful mining
life of the property.  These costs relate to reclaiming the pit and support
acreage at surface mines and sealing portals at deep mines.  Other costs of
final mine closure common to surface and underground mining are related to
reclaiming refuse and slurry ponds, eliminating sedimentation and drainage
control structures and dismantling or demolishing equipment or buildings used in
mining operations.  The Company also accrues for significant reclamation that is
completed during the mining process prior to final mine closure.  The
establishment of the final mine closure reclamation liability and the other
ongoing reclamation liability are based upon permit requirements and require
various estimates and assumptions, principally associated with costs and
productivities.

The Company reviews its entire environmental liability periodically and makes
necessary adjustments, including permit changes and revisions to costs and
productivities to reflect current experience.  These recosting adjustments are
recorded to cost of coal sales.  Adjustments included a decrease in the
liability of $8.1 million in the three and six months ended June 30, 2000.  The
adjustments occurred principally as a result of recent permit revisions at the
Company's idle mine properties in Illinois.  No adjustments were recorded in the
six months ended June 30, 1999.  The Company's management believes it is making
adequate provisions for all expected reclamation and other associated costs.

Legal Contingencies

                                       14


The Company is a party to numerous claims and lawsuits with respect to various
matters, including those discussed below. The Company provides for costs related
to contingencies, including environmental matters, when a loss is probable and
the amount is reasonably determinable. The Company estimates that its probable
aggregate loss as a result of such claims as of June 30, 2000 is $4.6 million
(included in other noncurrent liabilities). The Company estimates that its
reasonably possible aggregate losses from all material litigation that is
currently pending could be as much as $.5 million (before taxes) in excess of
the probable loss previously recognized. After conferring with counsel, it is
the opinion of management that the ultimate resolution of these claims, to the
extent not previously provided for, will not have a material adverse effect on
the consolidated financial condition, results of operations or liquidity of the
Company.

Dal-Tex Litigation. On July 16, 1998, ten individuals and The West Virginia
Highlands Conservancy filed suit in U.S. District Court for the Southern
District of West Virginia against the director of the West Virginia DEP and
officials of the Corps alleging violations of SMCRA and the Clean Water Act. The
plaintiffs alleged that the West Virginia DEP and the Corps have violated their
duties under SMCRA and the Clean Water Act by authorizing the construction of
"valley fills" under certain surface coal mining permits. These fills are the
large, engineered works into which the excess earth and rock extracted during
surface mining are placed. The plaintiffs also alleged that the West Virginia
DEP has failed to require (i) that lands mined are restored to "approximate
original contour" and (ii) that approved post-mining land uses are enforced
following reclamation.

Four indirect, wholly owned subsidiaries of the Company hold nine permits that
were identified in the complaint as violating the legal standards that the
plaintiffs requested the district court interpret. In addition, a pending permit
application for the Company's Dal-Tex operation (known as the "Spruce Fork
Permit") was specifically identified as a permit the issuance of which should be
enjoined. Three subsidiaries of the Company intervened in the lawsuit in support
of the Corps and the West Virginia DEP on August 6, 1998.

A partial settlement between the plaintiffs and the Corps was reached on
December 23, 1998. Pursuant to that settlement, all claims were dismissed
against the Corps for its alleged failure to execute its duties under the Clean
Water Act. The settlement agreement reached between the Corps and the plaintiffs
requires the preparation of a programmatic environmental impact statement (an
"EIS") under the National Environmental Policy Act of 1969 ("NEPA") to evaluate
the environmental effects of mountaintop mining. This EIS is scheduled to be
completed by January 2001. Until it is completed, any proposed fill greater than
250 acres in size must secure an individual Clean Water Act Section 404 "dredge
and fill" permit, instead of a general permit like the one the Corps indicated
it would issue for the Dal-Tex operation under its nationwide authorization
program. The Spruce Fork Permit was not included in the settlement, and the
claims against the Corps with respect to that permit were not dismissed.

On March 3, 1999, the district court issued a preliminary injunction which
prohibited the Corps from issuing a general Clean Water Act Section 404 dredge
and fill permit for the Dal-Tex operation and enjoined the Company from future
operations on the permit until a full trial on the merits could be held. As a
result of the entry of the preliminary injunction, the Company idled the Dal-Tex
mine on July 23, 1999.

On July 26, 1999, the plaintiffs and the West Virginia DEP tendered to the
district court a proposed consent decree which would resolve most of the
remaining issues in the case. Pursuant to the proposed consent decree, the West
Virginia DEP agreed in principle to amend its regulations and procedures to
correct alleged deficiencies. In addition, the parties agreed in principle on a
new definition of approximate original contour as it applies to mountaintop
mining, as well as to certain regulatory changes involving post-mining land
uses. After inviting public comment on the proposed consent decree, the court
entered the consent decree in a final order on February 17, 2000.

The Company's Hobet Mining subsidiary agreed as part of the consent decree to
revise portions of its Spruce Fork Permit application to conform to the new
definition of approximate original contour to be adopted by the West Virginia
DEP. Hobet Mining also agreed to seek an individual Clean Water Act Section 404
dredge and fill permit from the Corps as part of its future mining operation.
Before issuing that permit, the Corps must first complete an EIS to comply with
the provisions of NEPA. The completion of this EIS and issuance of all permits
are not expected until mid-2001 at the earliest.

The plaintiffs' allegation that the West Virginia DEP violated its duties under
the Clean Water Act by authorizing the construction of valley fills under
certain coal mining permits was not resolved by the consent decree. On

                                       15


October 20, 1999, the district court permanently enjoined the West Virginia DEP
from issuing permits that authorize the construction of valley fills as part of
coal mining operations. The West Virginia DEP complied with the injunction by
issuing an order banning the issuance of nearly all new permits for valley fills
and prohibiting the further advancement of nearly all existing fills. The West
Virginia DEP also filed an appeal of the district court's decision with the U.S.
Court of Appeals for the Fourth Circuit. On October 29, 1999, the district court
granted a stay of its injunction, pending the outcome of the appeal. The West
Virginia DEP rescinded its order on November 1, 1999 in response to the district
court's action.

It is impossible to predict the outcome of the West Virginia DEP's appeal. If,
however, the district court's decision is upheld, the Company and other coal
producers may be forced to close all or a portion of their mining operations in
West Virginia because of the prohibition on constructing valley fills for their
existing and future mines.

Cumulative Hydrologic Impact Assessment ("CHIA") Litigation. On January 20,
2000, two environmental organizations, the Ohio Valley Environmental Coalition
and the Hominy Creek Watershed Association, filed suit against the West Virginia
DEP in U.S. District Court in Huntington, West Virginia. In addition to
allegations that the West Virginia DEP violated state law and provisions of the
Clean Water Act, the plaintiffs allege that the West Virginia DEP's issuance of
permits for surface and underground coal mining has violated certain non-
discretionary duties mandated by SMCRA. Specifically, the plaintiffs allege that
the West Virginia DEP has failed to require coal operators seeking permits (i)
to conduct water monitoring to verify stream flows and ascertain water quality,
(ii) to always include certain water quality information in their permit
applications and (iii) to analyze the probable hydrologic consequences of their
operations. The plaintiffs also allege that the West Virginia DEP has failed to
analyze the cumulative hydrologic impacts of mining operations on specific
watersheds.

The plaintiffs seek an injunction to prohibit the West Virginia DEP from issuing
any new permits which fail to comply with all of the elements identified in
their complaint. The complaint identifies, and seeks to enjoin, three pending
permits that are sought by the Company's Mingo Logan subsidiary to continue
existing surface mining operations at the Phoenix reserve. If the permits are
not issued, it is possible that those operations will have to be suspended early
in 2001. It is impossible to predict whether this litigation will result in a
suspension of the affected surface mining operations. If, however, the
operations are suspended, the Company's financial condition and results of
operations could be adversely affected and, depending upon the length of the
suspension, the effect could be material. This matter does not affect Mingo
Logan's existing permits related to underground operations.

Lone Mountain Litigation. On October 24, 1996, the rock strata overlaying an
abandoned underground mine adjacent to the coal-refuse impoundment used by the
Lone Mountain preparation plant failed, resulting in the discharge of
approximately 6.3 million gallons of water and fine coal slurry into a tributary
of the Powell River in Lee County, Virginia. The U.S. Department of the Interior
notified the Company of its intention to file a civil action under the Clean
Water Act and the Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA") to recover alleged natural resource damages suffered as
a result of the discharge. The Company and the Interior Department have reached
an agreement in principle to settle this matter, which would require a payment
of $2.5 million by the Company. The settlement is subject to the Company and the
Interior Department entering into a definitive agreement. The Company's
consolidated balance sheet as of June 30, 2000 reflects a reserve for the full
amount of this settlement.

Other Litigation. On October 31, 1997, the EPA notified a Company subsidiary
that it was a potentially responsible party in the investigation and remediation
of two hazardous waste sites located in Kansas City, Kansas, and Kansas City,
Missouri. The Company's involvement arises from the subsidiary's sale, in the
mid-1980's, of fluids containing small quantities of polychlorinated biphenyls
("PCBs") to a company authorized to engage in the processing and disposal of
these wastes. Some of these waste materials were sent to one of the sites for
final disposal. The Company responded to the information request submitted by
the EPA on December 1, 1997. Any liability which might be asserted by the EPA
against the Company is not believed to be material because of the de minimis
quantity and concentration of PCBs linked to the Company. Moreover, the party
with which the subsidiary contracted to dispose of the waste material has agreed
to indemnify the Company for any costs associated with this action.

CERTAIN TRENDS AND UNCERTAINTIES

                                       16


Substantial Leverage; Variable Interest Rate; Restrictive Covenants

The Company has substantial leverage and significant debt service and lease and
royalty payment obligations. As of June 30, 2000, the Company had outstanding
consolidated indebtedness of approximately $1.2 billion, representing
approximately 84% of the Company's total capitalization.

The Company's ability to satisfy its debt service and lease payment obligations
will depend upon the future operating performance of its subsidiaries, which
will be affected by prevailing economic conditions in their markets, as well as
financial, business and other factors, certain of which are beyond their
control. Based upon current levels of operations, the Company believes that cash
flow from operations and available cash, together with available borrowings
under the Company's credit facilities, will be adequate to meet the Company's
future liquidity needs for at least the next several years. However, there can
be no assurance that the Company's business will generate sufficient cash flow
from operations or that future borrowings will be available in an amount
sufficient to enable the Company to fund its debt service and lease payment
obligations or its other liquidity needs.

The degree to which the Company is leveraged could have material consequences to
the Company and its business, including, but not limited to: (i) making it more
difficult for the Company to satisfy its debt service, lease payment and other
obligations; (ii) increasing the Company's vulnerability to general adverse
economic and industry conditions; (iii) limiting the Company's ability to obtain
additional financing to fund future acquisitions, working capital, capital
expenditures or other general corporate requirements; (iv) reducing the
availability of cash flow from operations to fund acquisitions, working capital,
capital expenditures or other general corporate purposes; (v) limiting the
Company's flexibility in planning for, or reacting to, changes in its business
and the industry in which it competes and (vi) placing the Company at a
competitive disadvantage when compared to competitors with less debt.

A significant portion of the Company's indebtedness bears interest at variable-
rates that are linked to short-term interest rates. If interest rates rise, the
Company's costs relative to those obligations would also rise.

Terms of the Company's credit facilities and leases contain financial and other
restrictive covenants that limit the ability of the Company to, among other
things, pay dividends, effect acquisitions or dispositions and borrow additional
funds and require the Company to, among other things, maintain various financial
ratios and comply with various other financial covenants. Failure by the Company
to comply with such covenants could result in an event of default which, if not
cured or waived, could have a material adverse effect on the Company.

Environmental and Regulatory Factors

Federal, state and local governmental authorities regulate the coal mining
industry on matters as diverse as employee health and safety, air quality
standards, water pollution, groundwater quality and availability, plant and
wildlife protection, the reclamation and restoration of mining properties, the
discharge of materials into the environment and surface subsidence from
underground mining. In addition, federal legislation mandates certain benefits
for various retired coal miners represented by the United Mine Workers of
America ("UMWA"). These regulations and legislation have had and will continue
to have a significant effect on the Company's costs of production and
competitive position.

New legislation, regulations or orders may be adopted or become effective which
may adversely affect the Company's mining operations, its cost structure or the
ability of the Company's customers to use coal. For example, new legislation,
regulations or orders may require the Company to incur increased costs or to
significantly change its operations. New legislation, regulations or orders may
also cause coal to become a less attractive fuel source, resulting in a
reduction in coal's share of the market for fuels used to generate electricity.
Any such regulation, legislation or order could have an adverse effect on the
Company's business, results of operations and financial condition and, depending
upon the nature and scope of the legislation, regulations or orders, the effect
could be material.

Permits.  Mining companies must obtain numerous permits that impose strict
regulations on various environmental and health and safety matters in connection
with coal mining, including the emission of air and water borne pollutants, the
manner and sequencing of coal extractions and reclamation, the storage, use and
disposal of non-hazardous and hazardous substances, and the construction of
fills and impoundments. Because regulatory

                                       17


authorities have considerable discretion in the timing of permit issuance and
because both private individuals and the public at large possess rights to
comment on and otherwise engage in the permitting process, including through
intervention in the courts, no assurance can be made that permits necessary for
mining operations will be issued or, if issued, that such issuance will be
timely or that permitting requirements will not be changed or interpreted in a
manner that would have a material adverse effect on the Company's financial
condition or results of operations.

As indicated by the legal action involving the Company's Dal-Tex operation which
is discussed in "Contingencies - Legal Contingencies - Dal-Tex Litigation"
above, the regulatory environment in West Virginia is changing with respect to
coal mining. No assurance can be made that the Fourth Circuit will overturn the
district court's decision in such legal action or that a legislative or other
solution will be achieved. If the district court's ruling is not overturned or a
legislative or other solution is not achieved, there could be a material adverse
effect on the Company's financial condition or results of operations.

NOx Emissions.  The use of explosives in surface mining causes oxides of
nitrogen ("NOx") to be emitted into the air. The emission of NOx from the use of
explosives at surface mines in the Powder River Basin is gaining increased
scrutiny from regulatory agencies and the public. The Company has taken steps to
monitor the level of NOx emitted during blasting activities at its surface mines
in the Powder River Basin and is continuing efforts to find a method of reducing
these NOx emissions. Any increase in the regulation of NOx emissions from
blasting activities could have an adverse effect on the Company's Powder River
Basin surface mines. Depending upon the nature and scope of any such
regulations, the effect on the mines could be material.

Kyoto Protocol.  On December 11, 1997, the U.S. government representatives at
the climate change negotiations in Kyoto, Japan, agreed to reduce the emissions
of greenhouse gases (including carbon dioxide and other gas emissions that are
believed to be trapping heat in the atmosphere and warming the earth's climate)
in the United States. The U.S. adoption of the requirements of the Kyoto
protocol is subject to conditions which may not occur and is also subject to the
protocol's ratification by the U.S. Senate. The U.S. Senate has indicated that
it will not ratify an agreement unless certain conditions, not currently
provided for in the Kyoto protocol, are met. At present, it is not possible to
predict whether the Kyoto protocol will attain the force of law in the United
States or what its impact would be on the Company. Further developments in
connection with the Kyoto protocol could have a material adverse effect on the
Company's financial condition and results of operations.

Customers.  In July 1997, the EPA proposed that twenty-two eastern states,
including states in which many of the Company's customers are located, make
substantial reductions in NOx emissions. The EPA expects the states to achieve
these reductions by requiring power plants to reduce their NOx emissions to a
level of 0.15 pounds of NOx per million Btu's of energy consumed. Many of the
states sued the EPA in the U.S. Court of Appeals for the District of Columbia
Circuit to challenge the new standard. In June 2000, the court upheld the
standard, but did not determine the timeframe within which the standard must be
implemented. To achieve the new standard, power plants may be required to
install reasonably available control technology ("RACT") and additional control
measures. The installation of such measures would make it more costly to operate
coal-fired utility power plants and, depending on the requirements of individual
state implementation plans, could make coal a less attractive fuel alternative
in the planning and building of utility power plants in the future.

The EPA is also proposing to implement stricter ozone standards by 2003. The
U.S. Court of Appeals for the District of Columbia Circuit has, however,
enjoined the EPA from implementing the new ozone standards on constitutional and
other legal grounds. The U.S. Supreme Court has agreed to review the lower
court's decision. It is impossible to predict the outcome of this legal action.
Any outcome that adversely affects the Company's customers or makes coal a less
attractive fuel source could, however, have an adverse effect on the Company's
financial condition or results of operations.

The U.S. Department of Justice, on behalf of the EPA, has filed a lawsuit
against seven investor-owned utilities and brought an administrative action
against one government-owned utility for alleged violations of the Clean Air
Act. The EPA claims that over thirty of these utilities' power stations have
failed to obtain permits required under the Clean Air Act for major improvements
which have extended the useful service of the stations or increased their
generating capacity. The Company supplies coal to seven of the eight utilities.
It is impossible to predict the outcome of this legal action. Any outcome that
adversely affects the Company's customers or makes coal a less

                                       18


attractive fuel source could, however, have an adverse effect on the Company's
financial condition or results of operations.

Reserve Degradation and Depletion

The Company's profitability depends substantially on its ability to mine coal
reserves that have the geologic characteristics that enable them to be mined at
competitive costs. There can be no assurance that replacement reserves,
particularly in central Appalachia, will be available when required or, if
available, that such replacement reserves can be mined at costs comparable to
those characteristic of the depleting mines. Exhaustion of reserves at
particular mines can also have an adverse effect on operating results that is
disproportionate to the percentage of overall production and operating income
represented by such mines. Mingo Logan's Mountaineer Mine is estimated to
exhaust its longwall mineable reserves in 2002. The Mountaineer Mine generated
$9.0 million and $22.1 million of the Company's total operating income for the
three and six months ended June 30, 2000, respectively.

Reliance on and Terms of Long-Term Coal Supply Contracts

The Company sells a substantial portion of its coal production pursuant to long-
term coal supply agreements and, as a consequence, may experience fluctuations
in operating results due to the expiration or termination of, or sales price
redeterminations or suspensions of deliveries under such coal supply agreements.
Other short- and long-term contracts define base or optional tonnage
requirements by reference to the customer's requirements, which are subject to
change as a result of factors beyond the Company's (and in certain instances the
customer's) control, including utility deregulation. In addition, certain price
adjustment provisions permit a periodic increase or decrease in the contract
price to reflect increases and decreases in production costs, changes in
specified price indices or items such as taxes or royalties. Price reopener
provisions provide for an upward or downward adjustment in the contract price
based on market factors. The Company has from time to time renegotiated
contracts after execution to extend the contract term or to accommodate changing
market conditions. The contracts also typically include stringent minimum and
maximum coal quality specifications and penalty or termination provisions for
failure to meet such specifications and force majeure provisions allowing
suspension of performance or termination by the parties during the duration of
certain events beyond the control of the affected party. Contracts occasionally
include provisions that permit a utility to terminate the contract if changes in
the law make it illegal or uneconomic for the utility to consume the Company's
coal or if the utility has unexpected difficulties in utilizing the Company's
coal. Imposition of new nitrous oxide emissions limits in connection with Phase
II of the Clean Air Act could result in price adjustments or in affected
utilities seeking to terminate or modify long-term contracts in reliance on such
termination provisions. If the parties to any long-term contracts with the
Company were to modify, suspend or terminate those contracts, the Company could
be adversely affected to the extent that it is unable to find alternative
customers at a similar or higher level of profitability.

From time to time, disputes with customers may arise under long-term contracts
relating to, among other things, coal quality, pricing and quantity. The Company
may thus become involved in arbitration and legal proceedings regarding its
long-term contracts. There can be no assurance that the Company will be able to
resolve such disputes in a satisfactory manner.

Although the Company cannot predict changes in its costs of production and coal
prices with certainty, the Company believes that in the current economic
environment of low to moderate inflation, the price adjustment provisions in its
older long-term contracts will largely offset changes in the costs of providing
coal under those contracts, except for those costs related to changes in
productivity. However, the increasingly short terms of sales contracts and the
consequent absence of price adjustment provisions in such contracts also make it
more likely that inflation related increases in mining costs during the contract
term will not be recovered by the Company through a later price adjustment.

                                       19


Potential Fluctuations in Operating Results; Seasonality

The Company may experience significant fluctuations in operating results in the
future, both on an annual and quarterly basis, as a result of one or more
factors beyond its control, including expiration or termination of, or sale
price redeterminations or suspensions of deliveries under, coal supply
agreements; disruption of transportation services; changes in mine operating
conditions; changes in laws or regulations, including permitting requirements;
unexpected results in litigation; work stoppages or other labor difficulties;
competitive and overall coal market conditions; and general economic conditions.

The Company's mining operations are also subject to factors beyond its control
that can negatively or positively affect the level of production and thus the
cost of mining at particular mines for varying lengths of time.  These factors
include weather conditions, equipment replacement and repair requirements;
variations in coal seam thickness, amount of overburden, rock and other natural
materials; and other surface or subsurface conditions.  Such production factors
frequently result in significant fluctuations in operating results.

Third quarter results of operations are frequently adversely affected by lower
production and resultant higher costs due to scheduled vacation periods at the
majority of the Company's mines.  In addition, costs are typically somewhat
higher during vacation periods because of maintenance activity carried on during
those periods.  These adverse effects may prevent the third quarter from being
comparable to the other quarters and also prevent the third quarter results from
being indicative of results to be expected for the full year.

Certain Contractual Arrangements

The Company owns a 99% interest in Arch Western Resources, LLC ("Arch Western"),
a joint venture that was formed in connection with the Company's acquisition of
the U.S. coal operations of Atlantic Richfield Company on June 1, 1998.  The
Limited Liability Company Agreement pursuant to which Arch Western was formed
provides that a subsidiary of the Company, as the managing member of Arch
Western, generally has exclusive power and authority to conduct, manage and
control the business of Arch Western.  However, if Arch Western at the time has
a debt rating less favorable than Ba3 from Moody's Investors Service or BB- from
Standard & Poors Ratings Group or does not meet certain specified indebtedness
and interest coverage ratios, then a proposal that Arch Western make certain
distributions, incur indebtedness, sell properties or merge or consolidate with
any other entity would require the consent of all the members of Arch Western.

In connection with the Arch Western transaction, the Company entered into an
agreement pursuant to which the Company agreed to indemnify another member of
Arch Western against certain tax liabilities in the event that such liabilities
arise as a result of certain actions taken prior to June 1, 2013, including the
sale or other disposition of certain properties of Arch Western, the repurchase
of certain equity interests in Arch Western by Arch Western or the reduction
under certain circumstances of indebtedness incurred by Arch Western in
connection with the Arch Western transaction.  Depending on the time at which
any such indemnification obligation were to arise, it could have a material
adverse effect on the business, results of operations and financial condition of
the Company.

The membership interests in Canyon Fuel are owned 65% by Arch Western and 35% by
a subsidiary of ITOCHU Corporation, a Japanese corporation.  The agreement which
governs the management and operations of Canyon Fuel provides for a Management
Board to manage its business and affairs.  Generally, the Management Board acts
by affirmative vote of the representatives of the members holding more than 50%
of the membership interests.  However, certain actions require either the
unanimous approval of the members or the approval of representatives of members
holding more than 70% of the membership interests.  The Canyon Fuel agreement
also contains various restrictions on the transfer of membership interests in
Canyon Fuel.

Pursuant to a stockholders agreement among the Company, Ashland and Carboex S.A.
("Carboex"), the Company has agreed to nominate for election as a director of
the Company a person designated by Carboex, and Ashland has agreed to vote its
shares of common stock in a manner sufficient to cause the election of such
nominee, in each case for so long (subject to earlier termination in certain
circumstances) as shares of common stock owned by Carboex represent at least 63%
of the shares of common stock acquired by Carboex in the Company's merger with
Ashland's subsidiary, Ashland Coal, Inc.  The Agreement terminates as to Ashland
once Ashland ceases to be the beneficial owner (as defined in Rule 13d-3(a)
under the Securities Exchange Act of 1934) of 10% or more of the Company's

                                       20


common stock. In addition, for so long as the various trusts for the benefit of
descendants of H.L. and Lyda Hunt and various corporations owned by trusts for
the benefit of descendants of H.L. and Lyda Hunt (collectively the "Hunt
Entities") have the collective voting power to elect one or more persons to
serve on the Board of Directors of the Company, the Company has agreed to
nominate for election as directors of the Company that number of persons
designated by certain of the Hunt Entities that could be elected to the Board by
the Hunt Entities by exercise of such voting power.

The Company's Amended and Restated Certificate of Incorporation requires the
affirmative vote of the holders of at least two-thirds of outstanding common
stock voting thereon to approve a merger or consolidation and certain other
fundamental actions involving or affecting control of the Company.  The
Company's Bylaws require the affirmative vote of at least two-thirds of the
members of the Board of Directors of the Company in order to declare dividends
and to authorize certain other actions.

Transportation

The coal industry depends on rail, trucking and barge transportation to deliver
shipments of coal to customers. Disruption of these transportation services
could temporarily impair the Company's ability to supply coal to its customers
and thus adversely affect the Company's business and operating results. In
addition, transportation costs are a significant component of the total cost of
supplying coal to customers and can significantly affect a coal producer's
competitive position and profitability. Increases in the Company's
transportation costs, or changes in such costs relative to transportation costs
incurred by providers of competing coal or of other fuels, could have an adverse
effect on the Company's business and results of operations.

Reliance on Estimates of Reserves; Title

There are numerous uncertainties inherent in estimating quantities of
recoverable reserves, including many factors beyond the control of the Company.
Estimates of economically recoverable coal reserves and net cash flows
necessarily depend upon the number of variable factors and assumptions, such as
geological and mining conditions (which may not be fully identified by available
exploration data and/or differ from experience in current operations),
historical production from the area compared with production from other
producing areas, the assumed effects of regulation by governmental agencies and
assumptions concerning coal prices, operating costs, severance and excise taxes,
development costs and reclamation costs, all of which may cause estimates to
vary considerably from actual results.

For these reasons, estimates of the economically recoverable quantities
attributable to any particular group of properties, classifications of such
reserves based on risk of recovery and estimates of net cash flows expected
therefrom prepared by different engineers or by the same engineers at different
times may vary substantially. Actual coal tonnage recovered from identified
reserve areas or properties and revenues and expenditures with respect to the
Company's reserves may vary from estimates, and such variances may be material.
No assurance can be given that these estimates are an accurate reflection of the
Company's actual reserves.

The Company's mining operations are conducted on properties owned or leased by
the Company.  The loss of any lease could adversely affect the Company's ability
to develop the applicable reserves.  Because title to most of the Company's
leased properties and mineral rights is not usually verified until a commitment
is made by the Company to develop a property, which may not occur until after
the Company has obtained necessary permits and completed exploration of the
property, the Company's right to mine certain of its reserves may be adversely
affected if defects in title or boundaries exist.  In addition, there can be no
assurance that the Company can successfully negotiate new leases or mining
contracts for properties containing additional reserves or maintain its
leasehold interests in properties on which mining operations are not commenced
during the term of the lease.

Factors Routinely Affecting Results of Operations

Any one or a combination of the following factors may occur at times or in a
manner that causes results of the Company's operations to deviate from
expectations: changing demand; fluctuating selling prices; contract penalties,
suspensions or terminations; operational, geologic, transportation and weather-
related factors; unexpected regulatory changes; results of litigation; or labor
disruptions.  Any event disrupting substantially all production at any of the

                                       21


Company's principal mines for a prolonged period would have a material adverse
effect on the Company's current and projected results of operations.  The effect
of such a disruption at the Mingo Logan operations would be particularly severe
because of the high volume of coal produced by those operations and the
relatively high contribution to operating income from the sale of such coal.
