                                 CONSOL ENERGY     


We rank among the largest coal companies in the United States based upon total
revenue, net income and operating cash flow. We produced 73 million tons of coal
during 1997. Our production accounted for 7% of the total tons produced in the
United States and 12% of the total tons produced in the eastern United States in
1997. We are one of America's premier coal companies by several measures:

     .    We mined more high-Btu bituminous coal than any other U.S. producer in
          1997.

     .    We are the largest coal producer east of the Mississippi River.

     .    We are the largest U.S. producer of coal from underground mines.

     .    We export more coal from the United States than any other coal
          producer or trading company.

     .    We have the second largest coal reserves among U.S. coal producers.

Our consistent financial performance has enabled us to establish a strong
history of cash generation and dividend payments.


PRINCIPAL MARKETS
    
Coal is an important source of energy for power generators in the United States.
Coal-fired plants produced 57% of the country's electricity in 1997. In 1997, we
sold 68% of our coal to U.S. electricity generators, most of which were located
east of the Mississippi River. More than two-thirds of the country's capacity
for generating electricity using coal is located east of the Mississippi River.
We can sell coal to these customers at a low delivered cost because of the
following factors:     

     .    Our mines are located close to eastern generating plants.
    
     .    Our mines are located on or near the inland waterway system and the
          major coal hauling railroads in the eastern United States. This
          reduces our customers' cost of transporting coal.     

     .    We are able to use highly productive mining techniques because we have
          favorable geologic conditions for mining.

DEMAND FOR CONSOL'S COALS

We believe that eastern, high-Btu coal will continue to be a valued source of
energy and that demand for such coal will continue to grow for the following
reasons.

                                       3
<PAGE>
 
    
     .    The electric utility industry soon will be deregulated in the United
          States which should increase competition and influence power companies
          to seek the lowest cost fuel for their generating plants. Fuel costs
          represent up to 78% of the variable cost of generating electricity at
          power plants that burn fossil fuels. Coal is the lowest cost fuel
          available to most electricity generators.     
    
     .    Electricity demand will grow as the economy grows. Generators of
          electricity can increase existing capacity at their plants by burning
          high-Btu coal. According to RDI, a coal industry consultant, in the
          aggregate, domestic coal-fired generating plants currently run at 65%
          capacity utilization. The optimal sustainable capacity utilization is
          85% for a typical plant, although many can run at higher rates for
          short periods of time. Electricity generators that burn coal will seek
          to meet increased electricity demand by using the available capacity
          of their existing power plants rather than building new power plants.
          Expanding capacity at existing power plants using coal makes economic
          sense if the price of electricity exceeds variable costs. However, a
          new plant would be built only if the price of electricity is expected
          to cover all costs, including capital costs.     
    
     .    A significant portion of the generating plants that use nuclear fuel
          is likely to be retired during the next 15 years because the operating
          licenses for many plants will expire. We believe that it is likely
          that licenses will not be renewed or costly requirements will be
          imposed as a condition to renewal. Although natural gas will replace
          some of this capacity, we believe that coal also will be used to
          replace retired nuclear capacity. Coal producers that can reduce
          mining costs and which have access to low-cost transportation should
          be well positioned to increase their share of the market.     
    
The Clean Air Act regulates the emission of sulfur dioxide and oxides of
nitrogen from coal combustion. This has led electric utilities to retrofit
generating plants with scrubbers, purchase emission allowances or burn
low-sulfur coal. To the extent that the cost of environmental control technology
continues to decline and environmental regulations tighten, we expect more
electricity generators that use coal to install scrubbers. As scrubbing
increases at existing generating plants, we believe that high- and medium-sulfur
coals with low delivered costs and high-Btu content will become increasingly
attractive to electricity generators because the cost of operating the scrubber
is typically less than 10% of variable costs. We believe that high-Btu content
is an important advantage because it lowers the delivered energy cost of the
coal. Transportation costs are based on tons and not heat content or heat
content per ton. As a result, higher Btu coals can have an inherent
transportation cost advantage, which lowers the delivered cost on a heat content
or energy content basis.     
    
We believe that once a scrubber is built, it can offer economic advantages
because of its relatively low operating costs, combined with the lower fuel
costs that higher sulfur, higher Btu coal can offer at many plants. We already
ship 65% of our high-sulfur coal product to scrubbed generating plants. The
retrofitting of additional generating plants with scrubbers would be an
advantage to us because we have large reserves of coal with a high-Btu 
content.     
    
The advantage of retrofitting scrubbers to generating plants should become
apparent as the current bank of sulfur dioxide emission allowances declines and
the more restrictive phase of the Clean Air Act becomes effective in 2000. A
sulfur dioxide emission allowance is an authorization under the Clean Air Act
for a power generating plant to emit one ton of sulfur dioxide. RDI recently
forecast that by 2015 the owners of plants with up to 80,000 megawatts of
existing coal-fired capacity may invest in scrubbers to comply with the new
environmental regulations. The majority of these plants are located east of the
Mississippi River. We believe that we are well positioned to benefit from these
developments. Increased investment in scrubbers may result from the ownership of
generating plants by independent power producers as a result of the deregulation
of the electricity generating industry. For example, in August 1998, Mission
Energy announced its intention to acquire a large generating station in central
Pennsylvania, Homer City, and to install a scrubber and other environmental
control technologies. Mission Energy has stated publicly that its strategy is to
continue to use high-Btu coal from Pennsylvania in order to maintain its
position as a low-cost producer of electricity.     

COAL RESERVES AND MINING OPERATIONS

At December 31, 1997, we had 4.8 billion tons of proved and probable coal
reserves. Our reserves are located in northern Appalachia (52%), central
Appalachia (13%), the midwest (21%) and the western United States and Canada
(14%). Approximately 65% of our coal reserves consist of high-Btu coal, which is
favored by many

                                       4
<PAGE>
 
    
power generators. In 1998, CONSOL produced 31.8 million tons of high-sulfur
coal, or 42% of our total production, and 33.7 million tons of low-and medium
sulfur coal, or 44% of our total production. In addition we produced 10.5
million tons of metallurgical grade tons, or 14% of our total 1998 production.
Approximately 77% of our coal reserves consist of high- and medium-sulfur coal
and 23% consist of low-sulfur coal. The size, quality and strategic location of
our reserves allow for the cost-effective expansion of many of our existing
mines and for new mine development.     
    
We currently operate 25 mining complexes. We lead the U.S. coal industry in
using longwall systems. Longwall systems are a mechanized, high-extraction
method of underground mining. We use these systems at 14 of our mines. Mines
with longwall systems accounted for 84% of the coal we mined in 1997. We are
able to expand production at longwall mines at very low incremental cost. Our
ability to source coal from our multiple longwall mines provides us with great
flexibility in meeting customer fuel requirements.     

STRATEGY
    
Our objective is to maintain and enhance our position as one of the premier coal
companies in the United States based on our financial strength, operating
capability and reserve position. We believe that we are well-positioned to grow
faster than the industry by reason of our low-cost structure and strong
financial position. Our strategy for achieving long-term growth does not depend
on either the construction of new coal combustion facilities or on high overall
growth in coal demand. Instead, we believe that most growth in demand for coal
will come from the expansion and increased use of existing power generating
facilities. We further believe that there will be a growing demand from
electricity generators for high-Btu fuels available at low delivered cost and
that the sulfur content of coal will not be the principal quality determining
coal demand within many markets. Our strategy reflects our belief that delivered
cost and Btu content will be the chief determinants of coal demand in these
markets. Accordingly, we believe that coal produced in the eastern United States
will continue to be an attractive fuel for electricity producers. Other markets
will continue to expand for lower Btu, low-sulfur coals as well, and we may make
acquisitions to participate in those markets.     

Specifically, we will implement our strategy by:

     .    strengthening our core operating position in northern Appalachia by
          continuing to make productivity improvements and by expanding the low-
          cost production capacity of existing mines at low incremental
          costs;

     .    developing new mining complexes in locations with reserves controlled
          by us where price levels or volume demand would generate attractive
          returns and where we can achieve low mining costs;

     .    making large-scale acquisitions, both in the United States and abroad,
          that will enable us to bring our mining expertise to coal markets
          where we do not have an existing presence; and

     .    making opportunistic acquisitions in our existing markets that will
          enable us to leverage our existing infrastructure and operations. For
          example, we recently acquired the Rochester & Pittsburgh Coal Company
          and the Vesta coal reserves in southwestern Pennsylvania. These
          acquisitions have strengthened our position in northern Appalachia.

     .    Net income has grown since 1994 at a compound annual growth rate of
          11% and reached $184 million in 1997. Growth has been in large measure
          based on the ability to expand production and improve productivity at
          existing mining complexes.     

                                       5
<PAGE>
 
     .    Net cash provided by operating activities has averaged $361 million
          per year since 1994, more than double capital expenditures, which
          averaged $173 million per year for the same period. During the same
          period, we paid $700 million in dividends, including an extraordinary
          dividend of $380 million in 1997, while reducing borrowings by $33
          million.
    
     .    We have investment-grade debt ratings.     
    
We believe that our financial strength will enable us to be a major
consolidating force in the coal industry. The top ten coal producers have
increased their share of production from 40% in 1990 to 54% in 1997, primarily
by acquiring other producers.     
    
EXPERIENCE IN ACQUIRING AND INTEGRATING COAL PROPERTIES     
    
Since 1990, we have acquired and successfully integrated the Rochester &
Pittsburgh Coal Company, Island Creek Coal Company from Occidental Petroleum,
Kentucky Criterion (now called Mill Creek) from Westmoreland Coal Company,
Greene Hill Coal Company properties from Pennsylvania Power and Light and the
Vesta coal reserves from A.T. Massey Coal Company.     

PRODUCTIVITY LEADERSHIP

We have maintained our strong financial performance despite generally lower coal
prices by increasing productivity and reducing unit costs.
    
     .    From 1994 to 1997, we maintained annual coal production at
          approximately 72 million tons while reducing our workforce by
          approximately 20% and reducing the number of mining complexes that we
          operate from 30 to 24. Consistent improvement in mine productivity
          reflects investment in capital improvements, including deployment of
          longwall mining systems, expertise in operations and favorable
          geologic conditions.     

     .    Between 1990 and 1996, we achieved a compound annual growth rate in
          productivity at our underground mines (measured in tons per manday) of
          8.4% compared with a growth rate for the industry for underground
          mines of 6.5%. As a result, we reduced costs per ton of coal mined by
          9.9% during the period.

     .    In 1997, our productivity increased by 11.3%.
    
We operate 25% of the longwall mining systems in the United States. Because of
the high production levels of these mining systems, we operate seven of the 20
largest mines east of the Mississippi River, measured by tons of coal produced
in 1997. These mines have high productivity and low variable cost structures.
Our extensive reserve base supports the expansion and life extension of existing
mines. Expansion of production at our longwall mines can be achieved at low
incremental cost because they are close to our reserves and are highly
mechanized operations. This is in contrast to many other producers with higher
cost structures and less extensive reserves, particularly certain companies
dependent on operations in central Appalachia.     

HIGH-QUALITY, STRATEGICALLY LOCATED RESERVE BASE
    
Our northern Appalachian reserves accounted for 52% of our total reserves at
year-end 1997. These reserves are near many coal users in the United States,
particularly generators of electricity, and are served by major
coal-transporting railroads and low-cost river transportation. Mining from these
reserves accounted for 68% of our production in 1997.     
    
Fifty-two percent of our reserve base is ranked as high-Btu and high-sulfur. The
high energy content of our coals benefits customers because they can produce
more electricity per pound of coal than with lower Btu fuels. However, the
sulfur content of the fuel creates combustion emissions which, by law, must be
controlled. During the past two decades, air quality laws have created some
market advantages for lower sulfur coals by imposing restrictions on
sulfur-dioxide emissions. These usually require high-sulfur coal users to switch
to lower sulfur coals, install scrubbers or, in more recent years, to buy
pollution allowances. Nevertheless, our     

                                       6
<PAGE>
 
    
high-sulfur coal remains competitive because of our transportation advantage and
generally higher Btu content. In addition, we have maintained our margins by
progressively reducing unit costs and increasing mine productivity. Further, we
believe as more generating plants are retrofitted with scrubbers, the high-Btu
content of our coals will become more desirable to electricity generators.     

EXPERIENCED MANAGEMENT TEAM

Our management team is one of the most experienced in the coal industry with an
average of over 24 years of coal industry experience. The management team has
demonstrated its ability to streamline operations and reduce costs. Management
has successfully expanded existing mines, built new mines and acquired
additional operations leading to an increase in our production, productivity and
earnings.

RESEARCH AND DEVELOPMENT CAPABILITIES

We operate the largest private research and development facility in the United
States devoted to the mining and use of coal. Our Research and Development
Department has pioneered several major technical developments in mining
technology. We also are in the forefront of U.S. coal companies in solving
coal-combustion and other challenges for customers which enables us to create
new business opportunities.

The Research and Development Department also works to improve the effectiveness
and the cost of pollution-control technologies. Our facilities and staff,
including 100 scientists and engineers, provide both testing and
field-diagnostic service to customers and potential customers.

BROAD, DIVERSE CUSTOMER BASE

We currently sell coal to more than 160 different customers, including
financially strong domestic utilities. Our three largest customers are Allegheny
Energy, Pennsylvania Power Company and Detroit Edison. During 1998, we will sell
about 61% of our production under contracts with terms exceeding one year. These
contract customers represent a base of nearly 60 companies, both domestic and
foreign, including generators of electricity, steel mills, heavy manufacturers,
chemical plants, cement plants and paper manufacturers.

                     SUMMARY FINANCIAL AND OPERATING DATA

    
The following table provides summary financial and operating data of CONSOL
Energy for the periods indicated. We have derived the summary financial data for
the years ended December 31, 1993, 1994, 1995, 1996 and 1997 from our
consolidated financial statements, which have been audited by Ernst & Young LLP,
independent auditors. You may read the report of Ernst & Young LLP elsewhere in
this prospectus with respect to the financial statements at December 31, 1996
and 1997 and for the years ended December 31, 1995, 1996 and 1997. We have
derived the summary financial data for the nine months ended September 30, 1997
and 1998 and at September 30, 1998 from our unaudited interim financial
statements included elsewhere in this prospectus which, in our opinion, include
all adjustments necessary for the fair presentation of such data for the
unaudited interim periods. The results of operations for the nine months ended
September 30, 1998 do not necessarily indicate what the results of operations
will be for the entire year ending December 31, 1998. After this offering, we
expect to change our fiscal year from a calendar year to a year ending on June
30. We will have a transitional fiscal period ending June 30, 1999. Our first
full fiscal year ending June 30 will be the year that starts July 1, 1999 and
ends June 30, 2000. You should read the information in the following tables in
conjunction with "Management's Discussion and Analysis of Results of Operations
and Financial Condition" and the Consolidated Financial Statements, included

(3)  Excludes cumulative effect of change in accounting principle. In 1993, we
changed accounting methods of accruing provisions for coal workers'
pneumoconiosis and workers' compensation. These changes were the result of a
reevaluation of measurement methods in light of the issuance of Statement of
Financial Accounting Standards No. 112, "Employers' Accounting for
Postemployment Benefits" (SFAS 112). We recorded income classified as a
cumulative effect of accounting change of $46.3 million representing income of
$70.3 million (net of contract deferrals of $67.0 million and income taxes of
$47.2 million) for the change in accounting for coal workers' pneumoconiosis,
and a charge of $23.9 million (net of income taxes of $16.1 million) for the
change in accounting for workers' compensation.

    
(4)  Pro forma net income assumes (A) payment of the extraordinary dividend in
1997 and the purchase of stock from DuPont Energy in 1998 as if they had

(6)  Gives effect to the purchase by us of shares of our common stock owned by
DuPont Energy and the payment of dividends in 1998 and related borrowings
incurred to finance the purchase and dividend. See "Certain Relationships and
Related Party Transactions."     

    
(7)  Gives effect to the receipt and application by us of an estimated $417
million in net proceeds from the offering. See "Use of Proceeds."     

    
(8)  Includes sales of coal produced by us and purchased from third parties. We
sold 3.3 million, 3.5 million, 2.7 million, 3.2 million, 3.1 million, 2.2
million and 2.1 million tons of coal that we purchased from third parties during
1993, 1994, 1995, 1996 and 1997 and the nine months ended September 30, 1997 and
1998, respectively.

southwestern Pennsylvania.     

    
(11) EBIT is defined as earnings, before cumulative effective of accounting
changes, before deducting net interest expense (interest expense less interest
income) and income taxes. EBITDA is defined as earnings, before cumulative
effect of accounting changes, before deducting net interest expense (interest
expense less interest income), income taxes and depreciation, depletion and
amortization. Although EBIT and EBITDA are not measures of performance
calculated in accordance with generally accepted accounting principles,
management believes that they are useful to an investor in evaluating CONSOL
Energy because they are widely used in the coal industry as measures to evaluate
a company's operating performance before debt expense and its cash flow. EBIT
and EBITDA do not purport to represent cash generated by operating activities
and should not be considered in isolation or as a substitute for measures of
performance in accordance with generally accepted accounting principles. In
addition, because EBIT and EBITDA are not calculated identically by all
companies, the presentation here may not be comparable to other similarly titled
measures of other companies. Management's discretionary use of funds depicted by
EBIT and EBITDA may be limited by working capital, debt service and capital
expenditure requirements and by restrictions related to legal requirements,
commitments and uncertainties.

                                 RISK FACTORS

You should consider the following factors and the other information in this
prospectus before deciding to invest in the common stock.

    
THE COAL INDUSTRY IS HIGHLY COMPETITIVE     

    
We sell coal in markets that are highly competitive and affected by factors
beyond our control. We compete with coal producers in various regions of the
United States for domestic sales, and we compete both with domestic and overseas
producers for sales to international markets. Continued demand for our coal and
the prices that we will be able to obtain primarily will depend upon coal
consumption patterns of the domestic electric utility industry. Consumption by
the domestic utility industry is affected by the demand for electricity,
environmental and other governmental regulations, technological developments and
the price of competing coal and alternative fuel supplies including nuclear,
natural gas, oil or renewable energy sources, including hydroelectric power. We
also sell coal to overseas utilities and to the more specialized metallurgical
coal market which is significantly affected by both international demand and
competition. See "Business--Competition."     

    
SIGNIFICANT DECLINES IN COAL PRICES COULD ADVERSELY AFFECT US     

Our results of operations are highly dependent upon the prices received for our
coal. Any significant decline in prices for coal could have a material adverse
effect on our business, financial condition, results of operations and
quantities of reserves recoverable on an economic basis. If the industry
experiences significant price declines from current levels or other adverse
market conditions, we may not be able to generate sufficient cash flow from
operations to meet our obligations, including debt service obligations, make
planned capital expenditures and pay dividends. See "Management's Discussion and
Analysis of Results of Operations and Financial Condition."

    
WE DEPEND ON A FEW CUSTOMERS FOR A SIGNIFICANT PORTION OF OUR REVENUES     

    
During 1997, we derived 23% of our total revenue from sales to our two largest
customers, Allegheny Energy and a consortium of utility companies, including
Cleveland Electric Illuminating Company, Duquesne Light Company, Ohio Edison
Company, Pennsylvania Power Company and The Toledo Edison Company, referred to
as the CAPCO companies. Allegheny Energy alone accounted for more than 10% of
our total revenues during 1997. We currently have five contracts with Allegheny
Energy and one with CAPCO. The CAPCO contract expires December 31, 1999. Our
contracts with Allegheny Energy expire in 2001, 2002, 2004 and 2005. We have
engaged in discussions with both customers to either extend existing long-term
contracts or enter into new contracts. There can be no assurance that these
customers either will extend or enter into new long-term contracts or, in the
absence of long-term contracts, that they will continue to purchase the same
amount of coal as they have in the past or on terms, including pricing terms, as
favorable to us as under existing agreements. Based on current market
conditions, we anticipate that the contract expiring in 1999, if renegotiated,
would provide for less favorable pricing terms. The loss of either customer or
changes in the amounts of coal that they purchase from us or the terms on which
they buy could have a material adverse effect on our business, financial
condition and results of operations. See "Management's Discussion and Analysis
of Results of Operations and Financial Condition" and "Business--Coal
Contracts."     
                                       12
<PAGE>
 
    
OUR CUSTOMERS MAY NOT EXTEND EXISTING OR ENTER INTO NEW LONG-TERM CONTRACTS     

    
During 1997, sales under long-term coal supply contracts generated approximately
66% of our total revenue from coal sales. These contracts contribute to the
stability and profitability of our operations by providing predictability of
production volumes and sales prices. Changes in regulations governing the
electric utility industry may make it more difficult for us to enter into
long-term contracts with our electric utility customers, as these customers may
become more sensitive to long-term price or quantity commitments in a more
competitive environment. A substantial decrease in the amount of coal sold by us
pursuant to long-term contracts could subject our revenue stream to increased
volatility and adversely affect our profitability. See "Business--Coal
Contracts."     

    
THE EXPIRATION OF LONG-TERM CONTRACTS WITH FAVORABLE PRICING OR CONTRACT
PROVISIONS ALLOWING FOR THE RENEGOTIATION OF PRICES COULD REDUCE OUR
PROFITABILITY    

The profitability of our long-term coal supply contracts depends on a variety of
factors, varies from contract to contract and fluctuates during the contract
term, depending on contract provisions, our actual production costs and other
factors. In addition, provisions for adjustment or renegotiation of prices and
other provisions may increase our exposure to short-term coal price volatility.
If a substantial portion of our long-term contracts were modified or terminated,
we would be affected adversely to the extent that we are unable to find other
customers at the same level of profitability. Because the price of coal has
declined in recent years, some of our long-term contracts are for prices above
current spot market prices. The loss of certain of our long-term contracts could
have a material adverse effect on our business, financial condition and results
of operations. See "Management's Discussion and Analysis of Results of
Operations and Financial Condition" and "Business--Coal Contracts."

    
DISPUTES WITH OUR CUSTOMERS CONCERNING CONTRACTS CAN RESULT IN LITIGATION     

From time to time we have disputes with our customers over the provisions of
long-term contracts relating to, among other things, coal quality, pricing and
quantity. We currently are involved in litigation with one customer and another
customer has made an arbitration demand. We may become involved in similar
proceedings in the future. There can be no assurance that we will be able to
resolve existing and future disputes in a satisfactory manner. See
"Business--Legal Proceedings."

    
COAL MINING IS SUBJECT TO UNEXPECTED DISRUPTIONS     

    
Our mining operations are predominantly underground mines using longwall mining
methods. These mines are subject to conditions or events beyond our control that
could disrupt operations and affect the cost of mining at particular mines for
varying lengths of time. These include: fires and explosions from methane;
mining and processing equipment failures; changes in geologic or hydrologic
conditions; inability to acquire mining rights or permits; or other disruptions
to the mining process. We generally do not maintain third-party insurance
against underground mining risks.     

    
DECLINES IN THE PRICES WE RECEIVE REQUIRE THAT WE CONTINUE TO REDUCE OPERATING
COSTS AND IMPROVE EFFICIENCIES    
 
    
We historically have improved productivity and reduced the costs of our
operations. Such improvements are important because they have enabled us to
maintain margins even despite the expiration of above market long-term
contracts. We intend to continue to reduce operating costs and improve
efficiencies. However, there can be no assurance that such efforts will be
successful. See "Management's Discussion and Analysis of Results of Operations
and Financial Condition."     

                                       13
<PAGE>
 
UNION REPRESENTED LABOR FORCE

At September 30, 1998, the United Mine Workers of America represented
approximately 50% of our workforce. Of our coal production in 1997, 65% or 47.1
million tons of coal was produced at mines where the maintenance and production
workforce was represented by the United Mine Workers of America. The current
National Bituminous Coal Wage Agreement, the wage agreement which applies to
substantially all of our represented employees at our mining operations, became
effective on January 1, 1998, and continues through December 31, 2002. Certain
of our competitors have lesser levels of representation. Because of the
increased risk of strikes and other related work actions, in addition to higher
labor costs, which may be associated with represented operations in the coal
industry, our non-represented competitors may have a competitive advantage in
areas where they compete with our represented operations. If some or all of our
current non-represented operations were to become represented, we could incur
increased risk of work stoppages and higher labor costs. The ten-month United
Mine Workers of America strike in 1993 had a material adverse effect on our
results of operations. See "Business--Employees and Labor Relations."

    
TRANSPORTATION DISRUPTIONS COULD IMPAIR OUR ABILITY TO SELL COAL     

    
Coal producers depend upon rail, barge, trucking, overland conveyor and other
systems to provide access to markets. One of our major rail transportation
providers, Conrail, recently was acquired by CSX Transportation, Inc. and
Norfolk Southern Corporation. The integration of Conrail into CSX Transportation
and Norfolk Southern is expected to begin June 1, 1999, although we understand
that certain steps have been taken already. We have had meetings with both rail
carriers to discuss specifically issues relating to the integration of Conrail,
CSX Transportation and Norfolk Southern operations and to seek to ensure
continued service during the period of integration. Although we have not yet
experienced any service disruptions because of the merger, disruptions in
service may occur during the transition period. We do not know how long the
transition period will last. Disruption of transportation services because of
problems arising from the integration process or from weather-related problems,
strikes, lock-outs or other events could temporarily impair our ability to
supply coal to customers and could have a material adverse effect on our
business, financial condition and results of operations.     

    
TRANSPORTATION COSTS ARE CRITICAL TO OUR CUSTOMERS' PURCHASING DECISIONS     

Transportation costs represent a significant portion of the total cost of coal
and, as a result, the cost of delivery is a critical factor in a customer's
purchasing decision. Although increases in transportation costs could give our
operations in northern Appalachia a competitive advantage over coal mined in
other regions, such increases could make coal a less competitive source of
energy. Such increases could have a material adverse effect on our ability to
compete with other energy sources and on our business, financial condition and
results of operations. See "Management's Discussion and Analysis of Results of
Operations and Financial Condition."

    
A SUBSTANTIAL PORTION OF OUR COAL HAS HIGH-SULFUR CONTENT WHICH MAY MAKE IT MORE
COSTLY TO USE BECAUSE OF THE CLEAN AIR ACT    

    
The Clean Air Act limits the ability of some of our customers to burn higher
sulfur coals unless they install scrubbers, purchase sulfur dioxide emission
allowances or blend high-sulfur coal with low-sulfur coal. The development of
our high-sulfur coal reserves is dependent on the cost of such emission
allowances, the cost and availability of low-sulfur coal and whether electric
utilities install scrubbers to meet the more stringent SO2 emissions
requirements of the Clean Air Act which will become effective in 2000. See "Coal
Industry Overview" and "Business--Coal Reserves."     

                                       14
<PAGE>
 
    
THE DEVALUATION OF FOREIGN CURRENCIES COULD ADVERSELY AFFECT THE COMPETITIVENESS
OF OUR COAL ABROAD     

    
We compete in international markets with coal produced in other countries,
including principally Australia, South Africa, Colombia, Venezuela and
Indonesia. Coal is sold internationally in U.S. dollars. As a result, mining
costs in competing producing countries may be reduced in U.S. dollar terms based
on currency exchange rates. Devaluation of currencies in producing countries
could adversely affect the competitiveness of U.S. coal in international markets
and could have a material adverse effect on our business, financial condition
and results of operations. We do not engage in currency hedging transactions.
See "Business--Competition."     

    
WE ACCRUE FOR CERTAIN LONG-TERM LIABILITIES BASED UPON CERTAIN ASSUMPTIONS WHICH
MAY NOT MATERIALIZE     

We provide various health and welfare benefits to inactive and retired
employees. These obligations have been estimated by us based on certain
assumptions described in Notes 1, 14 and 15 of the Notes to Consolidated
Financial Statements. At September 30, 1998, the current and non-current
portions of these obligations include: post retirement medical and life
insurance ($1,289 million); coal workers' pneumoconiosis ($496 million);
workers' compensation ($248 million); salary retirement ($23 million), and
long-term disability ($28 million). These obligations are unfunded except for
salary retirement and long-term disability which are partially funded.

We have obligations arising under various federal and state environmental laws
and regulations. These obligations are estimated by us based on permit
requirements and various assumptions concerning costs and production. At
September 30, 1998, the current and non-current portion of these obligations
include mine closing ($286 million) and reclamation ($34 million). These
obligations are unfunded.

If our assumptions do not materialize as expected, cash expenditures and costs
could be materially greater than those reflected in our financial statements.
See "Management's Discussion and Analysis of Results of Operations and Financial
Condition."

    
REGULATORY RISKS ARE INHERENT AND SUBSTANTIAL IN OUR BUSINESS     

    
General Risks. The coal mining industry is subject to regulation by federal,
state and local authorities on matters such as employee health and safety,
permit and licensing requirements, air quality standards, water pollution, plant
and wildlife protection, reclamation and restoration of mining properties after
mining is completed, the discharge of materials into the environment, surface
subsidence from underground mining and the effects that mining has on
groundwater quality and availability. In addition, the industry is affected by
legislation mandating certain benefits for current and retired coal miners.     

    
Numerous governmental permits and approvals are required for mining operations.
We may be required to prepare and present to federal, state and local
authorities data pertaining to the effect or impact that any proposed
exploration for or production of coal may have upon the environment.
Requirements imposed by any such authority may be costly and time-consuming and
may delay commencement or continuation of exploration or production operations.
     

The possibility also exists that new legislation or regulations and orders may
be adopted which may materially adversely affect our mining operations, our cost
structure or our customers' ability to use coal. New legislation and new
regulations under existing laws related to the protection of the environment,
which would further regulate or tax the coal industry, may also require us or
our customers to change operations significantly or incur increased costs. Such
legislation, if enacted, could have a material adverse effect on our business,
financial condition and results of operations. See "Regulation."

    
The Clean Air Act Affects Our Operations and Could Influence The Purchasing
Decisions Of Our Customers. The Clean Air Act and corresponding state laws that
regulate emissions into the air affect coal mining     

                                       15

operations. Direct impact on coal mining and processing operations may occur
through the Clean Air Act permit and emissions control requirements relating to
particulate matter including, without limitation, fugitive dust. In July 1997,
the U.S. Environmental Protection Agency adopted new, more stringent National
Ambient Air Quality Standards for particulate matter and ozone which are
expected to be implemented by 2003. The impact of the new National Ambient Air
Quality Standards on the coal industry will depend on the policies and control
strategies implemented by states under the Clean Air Act, but could have a
material adverse effect on our business, financial condition and results of
operations.     

    
The Clean Air Act affects coal mining operations indirectly by extensively
regulating the emission into the air of SO2 and other compounds, including
nitrogen oxides, emitted by coal-fueled power plants. The Clean Air Act places
limits on SO2 emissions from electric power generation plants. The initiation of
a second phase of emission reductions beginning in 2000 could affect adversely
the demand for higher sulfur coal, which currently accounts for a substantial
portion of our sales, as additional coal-burning electric power generation
plants become subject to the restrictions of the Clean Air Act. The extent to
which the switch by utilities to lower sulfur coal or other low-sulfur fuels
would materially adversely affect us would depend upon a number of factors,
including the cost structure of our operations.     

    
The Clean Air Act also affects coal mining operations by requiring utilities
that currently are major sources of nitrogen oxides in moderate or higher ozone
nonattainment areas to install reasonably available control technology. The
Environmental Protection Agency recently announced a proposal that would require
22 eastern states to reduce substantially nitrogen oxide emissions by the year
2003. The effect which such regulations or other requirements that may be
imposed in the future could have on the coal industry in general and on us in
particular cannot be predicted with certainty. No assurance can be given that
the implementation of the Clean Air Act, the new National Ambient Air Quality
Standards or any other future regulatory provisions will not materially
adversely affect our business, financial condition and results of 
operation.     

    
The Passage Of Legislation Responsive To The Framework Convention On Global
Climate Change Could Have An Adverse Effect On Our Business. The United States
and more than 160 other nations are signatories to the 1992 Framework Convention
on Global Climate Change which is intended to limit or capture emissions of
greenhouse gases, such as carbon dioxide. Although the U.S. Senate has not yet
ratified the Kyoto Protocol and no comprehensive regulations controlling
greenhouse gas emissions have been enacted, efforts to control greenhouse gas
emissions could result in reduced use of coal if electric power generators
switch to lower carbon sources of fuel. Such restrictions could have a material
adverse effect on our business, financial condition and results of 
operations.     

    
We Are Subject to the Clean Water Act Which Imposes Monitoring and Reporting
Obligations. The federal Clean Water Act affects coal mining operations by,
among other things, imposing restrictions on effluent discharge into waters.
Regular monitoring, as well as compliance with reporting requirements and
performance standards, are preconditions for the issuance and renewal of permits
governing the discharge of pollutants into water. We believe that we have
obtained all permits required under the Clean Water Act. However, there can be
no assurance that requirements under the Clean Water Act will not materially
adversely affect our business, financial condition and results of operations.
See "Regulation."     

    
Deregulation of the Electric Utility Industry Could Lead to Efforts to Reduce
Coal Prices. Deregulation of the electric utility industry, when implemented,
will enable industrial, commercial and residential customers to shop for the
lowest cost supply of electricity. This fundamental change in the power industry
may result in efforts to reduce coal prices, which could have a material adverse
effect on our business, financial condition and results of operations.     

    
We Have Significant Employee and Retiree Benefit Obligations. Under Black Lung
benefits legislation, each coal mine operator is required to make payments of
pneumoconiosis (black lung) benefits to (1) current and     

                                       16
<PAGE>
 
    
former coal miners, (2) certain survivors of a miner who dies from black lung
disease and (3) a trust fund for the payment of benefits and medical expenses to
claimants who last worked in the coal industry prior to January 1, 1970, or
where no responsible coal mine operator has been identified for claims where a
miner's last coal employment was after December 31, 1969. In addition to federal
acts, we are also liable under various state statutes for pneumoconiosis claims.
Our pneumoconiosis (black lung) benefits liabilities totaled approximately $496
million on our balance sheet at September 30, 1998. The impact of these costs
has not been significant for the nine-month period ended September 30, 1998. The
related cash payment for such liability was $7 million.     

    
In recent years, legislation on black lung reform has been introduced but not
enacted in Congress. It is possible that such legislation will be reintroduced
for consideration by Congress. If any of the proposals included in such or
similar legislation is passed, the number of claimants who are awarded benefits
could significantly increase. There can be no assurance that any such changes in
black lung legislation, if approved, will not have a material adverse effect on
our business, financial condition and results of operation.     

The U.S. Department of Labor has issued proposed amendments to the regulations
implementing the federal black lung laws which, among other things, establish a
presumption in favor of a claimant's treating physician and limit a coal
operator's ability to introduce medical evidence regarding the claimant's
medical condition. If adopted, the amendments could have an adverse effect on
us, the extent of which cannot be accurately predicted.

Additionally, we are required to compensate employees for work-related injuries.
Our workers' compensation liabilities were $248 million at September 30, 1998.
The amount that was included as a cost for the nine-month period ended September
30, 1998 was $37 million, while the related cash payment for such liability was
$31 million. In addition, several states in which we operate consider changes in
workers' compensation laws from time to time. Such changes, if enacted, could
adversely affect our business, financial condition and results of operation.

The Coal Industry Retiree Health Benefits Act of 1992 requires us to make
payments to fund the cost of health benefits for our and other coal industry
retirees. We made payments of $32 million and $27 million in 1997 and for the
nine months ended September 30, 1998, respectively. See Note 14 of Notes to
Consolidated Financial Statements. As a result of a U.S. Supreme Court decision
rendered in 1998, we may be required to increase our share of such payments.
However, the magnitude of such increase, if any, cannot be determined at this
time.

    
We Are Subject To Reclamation, Mine Closure and Subsidence Regulations And Must
Accrue For The Estimated Costs Of Complying With Such Regulations. The federal
Surface Mining Control and Reclamation Act of 1977 and similar state statutes
require that we obtain and periodically renew permits for mining operations and
that our mine property be restored in accordance with specified standards and an
approved reclamation plan. States also impose on mine operators the
responsibility for repairing or compensating for damage occurring on the surface
as a result of mining operations.     

We accrue for the costs of current mine disturbance and of final mine closure,
including the cost of treating mine water discharge where necessary, over the
estimated useful mining life of the property. The establishment of liability for
the current disturbance and final mine closure reclamation is based upon permit
requirements and requires various estimates and assumptions, principally
associated with costs and production levels. The reclamation costs, mine-closing
costs and other environmental liability accruals were $321 million at September
30, 1998. The amount that was included as an operating expense for the
nine-month period ended September 30, 1998 was $7 million, while the related
cash payment for such liability in such period was $22 million. Although our
management believes it is making adequate provisions for all expected
reclamation and other costs

                                       17
<PAGE>
 
associated with mine closures, future operating results would be adversely
affected if such accruals were later determined to be insufficient.

    
We Could Incur Significant Costs Under Federal and State Superfund Statutes.
Risks of environmental liability are inherent with respect to both current and
past coal mining activities. The Comprehensive Environmental Response,
Compensation and Liability Act and similar state laws create liabilities for
investigation and remediation for releases of hazardous substances to the
environment and damages to natural resources. Our current and former coal mining
operations currently incur, and will continue to incur, expenditures associated
with the investigation and remediation of environmental matters, including
underground storage tanks, solid and hazardous waste disposal and other matters
under the Comprehensive Environmental Response, Compensation and Liability Act
and state environmental laws.     

    
From time to time, we have been the subject of administrative proceedings,
litigation and investigations relating to environmental matters. We have been
named as a potentially responsible party at several Superfund sites. Based on
various factors, we believe that the liabilities associated with such Superfund
sites should not have a material adverse effect on our financial condition or
results of operations. However, there can be no assurance that we will not
become involved in future proceedings, litigation or investigations or that such
liabilities will not be material.     

While we believe that we have accrued for the costs likely to be incurred for
these environmental matters, and that those costs are not likely to have a
material adverse effect upon our business, financial condition and results of
operations, there can be no assurance that total costs and liabilities for these
environmental matters will not increase in the future. The magnitude of the
liability and the cost of complying with these environmental laws cannot be
predicted with certainty due to the lack of specific information available with
respect to many sites, the potential for new or changed laws and regulations and
for the development of new remediation technologies and the uncertainty
regarding the timing of work with respect to particular sites. As a result,
there can be no assurance that material liabilities or costs related to
environmental matters will not be incurred in the future or that our liabilities
will not be adversely affected by such environmental liabilities or costs. In
addition, there can be no assurance that changes in laws or regulations would
not affect the manner in which we are required to conduct our operations. See
"Regulation."

    
RHEINBRAUN MAY OWN AS MUCH AS 67.8% OF OUR COMMON STOCK AFTER THE OFFERING AND
WILL BE ABLE TO CONTROL SIGNIFICANT DECISIONS BY CONSOL    

    
After this offering, Rheinbraun A.G. and Rheinbraun US GmbH will together own
67.8% of our outstanding shares of common stock (65% if the underwriters'
over-allotment option is exercised in full). These principal stockholders will
be able to direct the election of all of the members of our Board of Directors
and exercise a controlling influence over our business and affairs, including
any determinations with respect to:     

     .   mergers or other business combinations;

     .   our acquisition or disposition of assets;

     .   our incurrence of indebtedness;

     .   the issuance of any additional shares of our common stock or other
         equity securities; and

     .   the payment of dividends.

                                       18
<PAGE>
 
Similarly, the principal stockholders will have the power to:

     .   determine matters submitted to a vote of our stockholders without the
         consent of our other stockholders;

     .   prevent or cause a change in control; or

     .   take other actions that might be favorable to the principal
         stockholders.

In the foregoing situations or otherwise, various conflicts of interest between
us and our principal stockholders could arise. Ownership interests of our
directors or officers in voting securities of our principal stockholders or
their affiliates or service as a director or officer or other employee of both
us and one of our principal stockholders or one of their affiliates could create
or appear to create potential conflicts of interest when directors and officers
and employees are faced with decisions that could have different implications
for us and our principal stockholders. See "Management" and "Principal
Stockholders."

    
OUR SHARE PRICE MAY DECLINE DUE TO SHARES ELIGIBLE FOR FUTURE SALE     

    
After this offering, a total of 54,403,357 shares of common stock will be owned
by Rheinbraun A.G. and Rheinbraun U.S. GmbH and 3,264,201 shares of common stock
will be owned by DuPont Energy. We cannot predict the effect, if any, that
future sales of shares of our common stock, or the availability of such shares
for sale would have on the market price prevailing from time to time.
Nevertheless, sales by us, Rheinbraun A.G., Rheinbraun U.S. GmbH or DuPont
Energy of substantial amounts of our common stock in the public market, or the
perception that such sales could occur, could adversely affect prevailing market
prices for our common stock offered in this offering. Such a reduction in the
market price of our common stock could impair our ability to raise additional
capital through future public offerings of our equity securities.     

    
Each of Rheinbraun A.G., Rheinbraun U.S. GmbH and DuPont Energy has agreed not
to dispose of its shares for a period of 180 days after the date of this
prospectus without the prior written consent of J.P. Morgan Securities Inc. See
"Shares Eligible for Future Sale."    

    
THE MARKET PRICE OF OUR COMMON STOCK COULD BE VOLATILE     

The trading price of our common stock could be subject to wide fluctuations in
response to, among other things, the following factors:

     .   variations in operating results;

     .   expectations of securities analysts;

     .   technological innovations by us or our competitors;

     .   changes in financial estimates by securities analysts; or

     .   the operating and stock price performance of other companies that
         investors may consider comparable to us.

In addition, the stock market in general has experienced extreme volatility that
often has been unrelated to the operating performance of particular companies
which are traded on the market. These broad market and industry fluctuations may
adversely affect the trading price of our common stock, regardless of our actual
performance.

OUR OPERATIONS COULD BE ADVERSELY AFFECTED BY DATA PROCESSING FAILURES AFTER
DECEMBER 31, 1999     

The year 2000 issue is the result of computer programs being written using two
digits rather than four to identify the applicable year and is an issue which
exists for all companies that rely on computers as the year 2000 approaches. The
failure to correct any such programs may result in incorrect results when
computers perform arithmetic operations, comparisons or data field sorting and
some non-information systems functions that rely on computers making
calculations. Based on recent assessments, we have determined that we will be
required to modify or replace some portions of our software, and, to a lesser
extent, our hardware so that those systems will properly utilize dates beyond
December 31, 1999. We do not expect costs in connection with any such
modifications and replacements to be material. However, if such modifications
and replacements are not made, or are not completed in a timely manner, the year
2000 issue may have a material adverse effect on our business, results of
operations and financial condition. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Impact of Year 2000 Issue."

                                USE OF PROCEEDS     

    
The net proceeds to CONSOL from the offering, after underwriting discounts,
commissions and expenses payable by CONSOL, are estimated to be approximately
$417 million (assuming an initial public offering price of $19.50 per share and
no exercise of the underwriter's over-allotment option). Such net proceeds will
be used to repay a portion of $600 million of commercial paper issued by CONSOL
in order to finance:     

    
     .   the November 1998 purchase of shares of common stock from DuPont Energy
         Company for $500 million,     

    
     .   the payment of dividends in 1998 totalling $48.8 million to Rheinbraun
         A.G. and Rheinbraun U.S. GmbH and $31.2 million to DuPont Energy
         Company and     

    
     .   the September 1998 acquisition of the Rochester & Pittsburgh Coal
         Company for $150 million and the refinancing of certain indebtedness
         aggregating $50 million of Rochester & Pittsburgh.     

    
The commercial paper to be repaid has maturities of up to 90 days and currently
bears interest at rates ranging from 5.55% to 5.68% per annum.     


                                DIVIDEND POLICY

    
The Board of Directors currently intends to declare and pay quarterly dividends
on common stock. It is expected that the first quarterly dividend after the
offering will be $.27 per share (a rate of $1.08 per share annually) and will be
paid in the third quarter of 1999. The declaration and payment of dividends by
CONSOL is subject to the discretion of the Board of Directors, and no assurance
can be given that CONSOL will pay such dividend or any further dividends. The
determination as to the payment of dividends will depend upon, among other
things, general business conditions, CONSOL's financial results, contractual and
legal restrictions regarding the payment of dividends by CONSOL, the credit
ratings of CONSOL, planned investments by CONSOL and such other factors as the
Board of Directors deems relevant.     

    
CONSOL paid ordinary cash dividends to its stockholders of $80 million in each
of 1995, 1996, 1997 and 1998. CONSOL also paid an extraordinary cash dividend to
its stockholders of $380 million in 1997. The dividends historically paid by
CONSOL are not indicative of its future dividend policy, particularly because
CONSOL was closely held prior to the offering. See "Management's Discussion and
Analysis of Results of Operations and Financial Condition--Liquidity and Capital
Resources."

              SELECTED CONSOLIDATED FINANCIAL AND OPERATING DATA
    
The following table sets forth selected consolidated financial and operating
data of CONSOL for the periods indicated. The selected consolidated financial
data for the years ended December 31, 1993, 1994, 1995, 1996 and 1997 have been
derived from the consolidated financial statements of CONSOL which financial
statements have been audited by Ernst & Young LLP, independent auditors. The
report of Ernst & Young LLP with respect to the financial statements at December
31, 1996 and 1997 and for the years ended December 31, 1995, 1996 and 1997
appears elsewhere in this Prospectus. The selected financial data for the nine
months ended September 30, 1997 and 1998 and at September 30, 1998 have been
derived from CONSOL's unaudited interim financial statements included elsewhere
in this Prospectus which, in the opinion of CONSOL, include all adjustments
necessary for the fair presentation of such data for the unaudited interim
periods. The results of operations for the nine months ended September 30, 1998
are not necessarily indicative of the results of operations to be expected for
the entire year ending December 31, 1998. After the offering, CONSOL expects to
change its fiscal year from a calendar year to a year ending on June 30. CONSOL
will have a transitional fiscal period ending June 30, 1999. CONSOL's first full
fiscal year ending June 30 will be the year that starts July 1, 1999 and ends
June 30, 2000. The information in the following table should be read in
conjunction with "Management's Discussion and Analysis of Results of Operations
and Financial Condition" and the Consolidated Financial Statements included
elsewhere in this Prospectus.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 RESULTS OF OPERATIONS AND FINANCIAL CONDITION


GENERAL
    
CONSOL ranks among the largest coal companies in the United States based upon
total revenue, net income and operating cash flow. CONSOL is the largest U.S.
producer of high-Btu bituminous coal, the largest producer of coal east of the
Mississippi River, the largest producer from underground mines and the largest
U.S. exporter of coal to international markets. CONSOL sells coal to more than
20 nations and serves markets in Europe, South America, Southeast Asia, Africa,
the Caribbean and North America. Production in 1997 totalled 73 million tons.
CONSOL accounted for 7% of total domestic tons produced and for 12% of tons
produced in the eastern United States during 1997. CONSOL currently operates 25
mining complexes. At December 31, 1997, CONSOL had 4.8 billion tons of proved
and probable coal reserves, the second largest reserve base among U.S. coal
producers.     

CONSOL has increased earnings over the last five years by (1) reducing unit
costs of production through productivity improvements, (2) expanding CONSOL
mines by investing in technology, thereby using the resulting production
increases to replace older, higher cost mines with depleted reserves, (3)
investing in acquisitions that complement existing operations, and (4)
successfully selling coal at prices that have enabled CONSOL to maintain margins
despite the expiration of above-market sales contracts. CONSOL will attempt to
continue to use these methods in the future.

CONSOL has maintained the delivered-cost competitiveness of its coals by
increasing productivity. CONSOL operates 25% of all longwall mining systems in
the United States, more than any other coal producer. The distinguishing
characteristic of longwall mines relative to other types of mines is a low
variable-cost structure due to highly mechanized operations. Expansion of
production from these mines can be achieved at low incremental cost. This has
allowed CONSOL to generate positive cash margins even under pricing pressures.
While tons produced by CONSOL have increased in each of 1995, 1996 and 1997,
CONSOL reduced employment at its mining complexes in operation by 11.8% from
December 31, 1995 through December 31, 1997 and the number of mining complexes
in operation from 30 to 24. During the same period, net income increased in each
year, from $130 million in 1995 to $153 million in 1996 and $184 million in
1997, as did net cash provided by operating activities which increased from $298
million in 1995 to $373 million in 1996 and $428 million in 1997.
    
CONSOL expects to continue to reduce its unit cost of production in the future.
CONSOL currently is expanding the preparation plant that serves the Bailey and
Enlow Fork operation and plans to improve underground haulage to ultimately
increase production nearly 25% from what already is a record level. CONSOL
replaced track haulage with more efficient belt haulage at its McElroy mine in
1997 and its Blacksville mine in 1998. Also at the McElroy mine, CONSOL is
constructing a raw coal silo that will allow greater efficiency at both the
plant and in the mine. At the Blacksville mine, CONSOL plans to accelerate the
lifting of coal from the vertical shaft in the mine, which is the current
bottleneck. CONSOL intends to convert the Shoemaker mine to an all-belt haulage
mine to further reduce its costs. CONSOL has plans to replace the Cardinal River
mine with the lower-cost Cheviot mine subject to satisfactory market conditions.
In 1999, the higher-cost Powhatan mine will deplete its reserves and it is
anticipated that the expanded McElroy and Shoemaker mines will more than offset
the production loss and do so at lower costs. CONSOL incorporates such
improvements routinely in its plans to continue to reduce cost.     
    
CONSOL also will increase its production through acquisitions where CONSOL
believes it has a competitive advantage and can generate value from
underperforming assets. In September 1998, CONSOL acquired Rochester &
Pittsburgh Coal Company. Rochester & Pittsburgh's principal asset is Mine No.
84, which has     

                                       26
<PAGE>
 
similar characteristics to the Bailey and Enlow Fork mines, and has the
potential to become a highly efficient mine.
    
CONSOL has successfully marketed its coal production, and has been able to
maintain margins despite the implementation in 1995 of the first phase of the
Clean Air Act. The second phase of the implementation of the Clear Air Act will
take effect in the year 2000. CONSOL plans to sell a significant portion of its
high-sulfur coal production after 2000 to scrubbed plants or to export markets.
Its medium-sulfur coals, such as coal produced at the Bailey, Enlow Fork and
Mine 84 mines, will be targeted to power plants that are unscrubbed but that can
continue to burn such coals with sulfur dioxide allowances.     
    
Although the Clean Air Act has had some effect on the price per ton of
high-sulfur coal, CONSOL believes that production costs will continue to be a
significant factor in setting prices. The coal market is a very competitive
market in which prices often are set by marginal cost producers. As producers
deplete their reserves, their cost of mining will increase. To date,
productivity improvements throughout the industry have offset cost pressures
resulting from the depletion of existing reserves. Generally, the price of
high-sulfur coal on a delivered basis is less than the price of low-sulfur coal
on a delivered basis. CONSOL believes that the price difference between high-and
low-sulfur coal likely will widen in the future because low-sulfur producers
will be required to mine higher cost reserves. The price of higher sulfur coals
also will rise because of depletion, but this increase may not be as fast as the
increase in low-sulfur coal. CONSOL believes that it is in a favorable position
in which cost reductions are available through continued productivity
improvements by mining its extensive reserves that are accessible to its
existing mines.     
    
CONSOL believes that many of the unscrubbed power plants also will retrofit
scrubbers when economical. Because of potential further tightening of clean air
regulations, particularly for sulfur dioxide and for mercury control, scrubbers
may be required. To the extent that plants install scrubbers, the cost of
operating a scrubber is approximately $.09 to $.12 per million Btus. In
addition, CONSOL believes that technologically-advantaged clean power plants
using high-Btu, low-delivered-cost coals to be more competitive than plants
generating electricity with natural gas. Because scrubbers are needed for all
new power plants that burn coal and may be required for existing coal burning
plants to continue to operate under tighter air regulations, CONSOL's coals
should sustain their advantage over low-sulfur coal that is produced farther
from CONSOL's markets and, as a result, have higher transportation costs.     

LONG-TERM CONTRACTS
    
During 1997, approximately 66% of CONSOL's total revenue from coal sales
(representing 46.9 million tons) resulted from sales under long-term contracts
(in excess of one year). These contracts contribute to the stability and
profitability of CONSOL's operations by providing predictability of production
volumes and sales prices. In addition, because the price of coal has declined in
recent years, some of CONSOL's long-term contracts are at prices above current
spot market. CONSOL's long-term contracts, existing at September 30, 1998, have
remaining terms ranging from one to 18 years and provide, in the aggregate, for
the delivery of 46 million tons in 1998, 42 million tons in 1999 and 24 million
tons in 2000, subject generally, to the satisfaction of certain conditions and
each contracting party's right to vary the number of tons delivered. The average
original term of our long-term contracts is 6.5 years. The average remaining
term of these contracts is 2.7 years.     
    
CONSOL's net income primarily is generated by low-cost mining operations with
sales volumes at market prices. However, CONSOL has fixed-price and
base-price-plus-escalation steam coal contracts that are above or below current
market prices. The following table sets forth for such contracts that were in
effect in 1997 (1) the number of tons deliverable, (2) the weighted average
price per ton paid or estimated to be payable and (3) the number of contracts.
Where contracts have price reopener provisions, such contracts have been
excluded from the table after the date on which they revert to market prices. Of
our 65 long-term contracts, 40 of these contracts have price reopener
provisions. The price reopener provisions in all but one of these 40 contracts
are     

                                       27
<PAGE>
 
    
at market price at the time of the reopening. One contract reopener is based on
production costs for labor and supplies for the mines supplying the coal.

Contracts that provided for the sale of 22 million tons in 1997 expire or revert
to market price prior to 2000. These contracts generated total revenues of $620
million in 1997. Based on CONSOL's estimate of market prices in 1997, if sales
under these contracts had been at market prices, CONSOL's revenues and net
income in 1997 would have been reduced by approximately $120 million and $75
million, respectively. During the past five years, CONSOL has been able to
offset the effects of the expiration of long-term contracts through cost savings
and productivity improvements. CONSOL anticipates that it will be able to
mitigate the impact of the expiration of such contracts. However, there cannot
be any assurance that it will be able to do so, particularly with the larger
volume expiring in 2000, and the inability to reduce costs and improve
productivity could have a material adverse effect on CONSOL's business,
operations and financial condition.     

CHANGE OF FISCAL YEAR
    
After the offering, CONSOL expects to change its fiscal year from a calendar
year to a year ending on June 30. CONSOL will have a transitional fiscal period
ending June 30, 1999. CONSOL's first full fiscal year ending June 30 will be the
year that starts July 1, 1999 and ends June 30, 2000. CONSOL is undertaking this
change in order to align its fiscal year with that of Rheinbraun. CONSOL is a
consolidated subsidiary of Rheinbraun.     


RESULTS OF OPERATIONS

NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED WITH NINE MONTHS ENDED SEPTEMBER
30, 1997
    
Revenue. Sales decreased 0.3% to $1,680 million for the nine-month interim
period ended September 30, 1998 from $1,685 million for the nine-month interim
period ended September 30, 1997. The decrease of $5 million was due mainly to a
decrease in sales of industrial supplies by $29 million due to a loss of a sales
contract and a decrease in sales of purchased coal by $10 million due to a loss
of a contract. It also reflected a general decrease in coal purchased by CONSOL
and sold to the export market. These decreases were offset by increased produced
coal sales of $37 million due mainly to a 2.3% increase in the volume of coal
sold. Coal sales prices for the 1998 interim period were comparable to those for
the 1997 interim period.     
    
Other income, which consists of interest income, gain (loss) on the disposition
of assets, service income, royalty income, rental income and certain other
income, decreased 27.5% to $37 million for the 1998 interim period compared with
$51 million for the 1997 interim period. The decrease of $14 million was due
primarily to a     

                                       28
<PAGE>
 
decrease in interest income resulting from a lower level of investment in
marketable securities and a decrease in the gain on sale of assets, partially
offset by a one-time payment received in 1998 pursuant to an agreement that
compensated CONSOL for not mining certain coal reserves.
    
Costs. Cost of goods sold and other operating charges decreased 2.7% to $1,158
million for the 1998 interim period compared with $1,190 million for the 1997
interim period. The decrease of $32 million primarily reflected lower costs as a
result of decreased industrial supply sales and decreased purchased coal sales.
Coal mine productivity (calculated in tons per manday) increased 7.1% for the
1998 interim period compared with the 1997 interim period. The productivity
increase was driven, in part, by increases in production at the McElroy mine,
which completed installation of a new belt haulage system at the end of 1997,
and the Enlow Fork mine, which installed a new longwall early in 1998.     
    
Selling, general and administrative expenses remained stable at $41 million for
the 1998 interim period and for the 1997 interim period.     
    
Depreciation, depletion and amortization increased 2.9% to $176 million for the
1998 interim period compared with $171 million for the 1997 interim period. The
increase of $5 million was primarily due to the increase in equipment placed in
service in the 1998 interim period.     
    
Interest Expense decreased 5.9% to $32 million for the 1998 interim period
compared with $34 million for the 1997 interim period. The decrease of $2
million was primarily due to a decrease in the average principal amount of
long-term debt outstanding during the period and more interest expense
capitalized in the 1998 interim period than in the 1997 interim period. This
decrease was partially offset by higher interest costs for short term commercial
paper due to higher principal balances outstanding during the 1998 interim
period compared to the 1997 interim period.     
    
Taxes other than income increased 3.5% to $148 million for the 1998 interim
period compared with $143 million for the 1997 interim period. The increase of
$5 million was primarily the result of an increase in production related taxes
due to increased production volumes and the exhaustion of the West Virginia
Business Investment and Jobs Expansion Tax Credit carryforward utilized in 1997.
This increase was partially offset by a reduction of property tax expense due
primarily to reduced assessments at recently closed facilities.     
    
Income Taxes. Income taxes increased 5.6% to $38 million for the 1998 interim
period compared with $36 million for the 1997 interim period, reflecting
increased earnings in the 1998 interim period. The estimated effective tax rate
was 23.6% for the 1998 interim period compared to 23.0% compared to the 1997
interim period.     

1997 COMPARED WITH 1996
    
Revenue. Sales decreased 2.2% to $2,285 million for 1997 compared with $2,336
million for 1996. The decrease of $51 million primarily was due to a decrease of
1.8 million tons, or 2.4%, due to a decrease in the volume of U.S. metallurgical
and international steam coal sold, partially offset by an improvement in average
sales price per ton.     

Other income increased 4.9% to $64 million for 1997 compared with $61 million
for 1996. The increase of $3 million primarily was due to an increase in royalty
income from a coal lease in Kentucky that began generating revenue in September
1996 and continued to generate revenue for the full year of 1997.

Costs. Cost of goods sold and other operating charges decreased 5.7% to $1,592
million for 1997 compared with $1,688 million for 1996 primarily as a result of
lower volume of CONSOL-produced coal sold in 1997 and lower average production
costs per ton. Coal mine productivity increased 11.3% in 1997 compared with
1996, 

                                       29

and nine mines set production records in 1997. The productivity improvement is
attributable mainly to investment in a longwall mining system at Shoemaker, in
underground coal haulage at McElroy, and in an underground storage bunker at
Buchanan.

Selling, general and administrative expenses increased 3.8% to $55 million for
1997 compared with $53 million for 1996. The increase of $2 million primarily
was due to an increase in salaries and related benefits.

Depreciation, depletion and amortization decreased 0.9% to $233 million for 1997
compared with $235 million for 1996.

Interest expense increased 2.2% to $46 million for 1997 compared with $45
million for 1996. The increase of $1 million reflected interest charges related
to disputed coal royalty payments offset by lower average debt levels resulting
from the repayment of $44 million of long-term debt during 1997.

Taxes other than income increased 1.1% to $189 million for 1997 compared with
$187 million in 1996. The increase of $2 million resulted from increases in
severance taxes and required tax payments for pneumoconiosis (black lung)
benefits, which arose because of higher production. The increase in severance
taxes also resulted from the expiration in December 1996 of the West Virginia
Business and Job Expansion Tax Credit representing a portion of the tax credit
that was carried forward to 1997. The increase in taxes was partially offset by
a reduction in property tax expense as a result of mine closures.

Income Taxes. Income taxes increased 38.9% to $50 million for 1997 compared with
$36 million for 1996. The increase of $14 million resulted primarily from
increased earnings and an increase in the effective tax rate from 19.1% in 1996
to 21.3% in 1997. The increased effective tax rate for 1997 primarily was
influenced by a decline in the impact of percentage depletion.


1996 COMPARED WITH 1995

Revenue. Sales increased 3.0% to $2,336 million for 1996 compared with $2,269
million for 1995. The increase of $67 million resulted from an increase of 5.9%
in the volume of coal sold. Volumes improved because of continued growth in the
U.S. economy and colder than normal temperatures in the first quarter which
boosted demand for steam coal from electricity generators. Record sales volumes
were recorded for CONSOL.

Other income increased 35.6% to $61 million for 1996 compared with $45 million
for 1995. The increase primarily reflected aggregate gains on sales of assets of
$14 million in 1996 compared to aggregate losses of $5 million on such sales in
1995. The loss in 1995 was influenced by the sale of gas properties in Virginia.

Costs. Cost of goods sold and other operating charges increased 5.5% to $1,688
million for 1996 compared with $1,600 million for 1995. The increase of $88
million primarily reflected increased volume of coal sales during 1996 offset in
part by lower average production costs per ton. Coal mine productivity improved
10.7%. Eight mines set productivity records and nine mines set production
records, including Enlow Fork, which produced 8.7 million tons, the most ever
for a U.S. underground mine. Productivity at Loveridge was enhanced following
the installation of a new longwall mining system.

Selling, general and administrative expenses remained stable at $53 million for
1996 and 1995.

Depreciation, depletion and amortization decreased 7.1% to $235 million for 1996
compared with $253 million for 1995. The decrease of $18 million primarily was
due to the amortization in full of certain capitalized mining costs and to the
sale of certain gas properties in 1995.

                                       30
<PAGE>
 
Interest expense decreased 16.7% to $45 million for 1996 compared with $54
million for 1995. The decrease of $9 million primarily was due to the lower
average principal amount and lower effective interest rates during 1996 compared
with 1995.

Taxes other than income decreased 7.0% to $187 million for 1996 compared with
$201 million for 1995. The decrease of $14 million was due primarily to the
enactment of the Virginia Coalfield Employment Enhancement Tax Credit in 1996,
which encouraged the creation and maintenance of coal mining jobs, and reduced
severance tax due to mines that were closed in 1995.

Income Taxes. Income taxes increased 56.5% to $36 million for 1996 compared with
$23 million for 1995. The increase of $13 million primarily was due to the
increase in earnings and an increase in the effective tax rate from 14.9% for
1995 to 19.1% for 1996. The effective tax rate increase resulted from a
reduction in alternative fuel tax credits because of the sale in 1995 of coalbed
methane gas operations that were eligible for such credit.


LIQUIDITY AND CAPITAL RESOURCES

CONSOL generally has satisfied its working capital requirements and funded its
capital expenditures and debt-service obligations from cash generated from
operations. CONSOL believes that cash generated from operations and its
borrowing capacity will be sufficient to meet its working capital requirements,
anticipated capital expenditures (other than major acquisitions), scheduled debt
payments and anticipated dividend payments for at least the next several years.
Nevertheless, the ability of CONSOL to satisfy its debt service obligations, to
fund planned capital expenditures or pay dividends will depend upon its future
operating performance, which will be affected by prevailing economic conditions
in the coal industry and financial, business and other factors, certain of which
are beyond CONSOL's control.

CONSOL frequently evaluates potential acquisitions. In the past, CONSOL has
funded acquisitions primarily with cash generated from operations, but CONSOL
may consider a variety of other sources, depending on the size of any
transaction, including debt or equity financing. There can be no assurance that
such additional capital resources will be available to CONSOL on terms which
CONSOL finds acceptable, or at all.

OPERATING CASH FLOWS
    
Net cash provided by operating activities was $298 million, $373 million and
$428 million in 1995, 1996 and 1997, respectively, and $243 million in the 1997
interim period and $263 million in the 1998 interim period. The increases in net
cash provided by operating activities reflect increases in net income and
changes in certain working capital requirements.     

CAPITAL EXPENDITURES
    
Capital expenditures were approximately $179 million in 1995, $169 million in
1996 and $201 million in 1997. CONSOL made such expenditures for replacement of
mining equipment, the expansion of mining capacity and projects to improve the
efficiency of mining operations. During the 1998 interim period, CONSOL spent
approximately $189 million for capital expenditures excluding the costs
associated with the acquisition of Rochester & Pittsburgh. Capital expenditures
included $42 million for replacement of longwall equipment, $31 million for
expansion of the Bailey preparation plant, $20 million for drilling new wells
and installing associated gas gathering equipment for CONSOL's coalbed methane
joint venture and $96 million for other maintenance-of-production projects,
including air shafts, replacement equipment and equipment rebuilds. Capital
expenditures during the fourth     

                                       31
<PAGE>
 
    
quarter of 1998 will be for maintenance of production. CONSOL anticipates that
it will spend approximately an additional $47 million for capital expenditures
during the fourth quarter of 1998. CONSOL spent approximately $150 million for
the acquisition of Rochester & Pittsburgh and $50 million to repay certain
indebtedness of Rochester & Pittsburgh. CONSOL used cash generated from
operations and cash made available from the issuance of commercial paper to fund
capital expenditures in the second half of 1998, the acquisition of Rochester &
Pittsburgh and the repayment of indebtedness of Rochester & Pittsburgh. CONSOL
anticipates making capital expenditures of approximately $260 million during
1999 and approximately $314 million during 2000, primarily for maintenance and
replacement of mining equipment and operations, and including $5 million during
1999 for pollution abatement and mine reclamation expenditures. Capital
expenditures for pollution abatement and reclamation currently are projected to
be $6.2 million for 2000 and $4.3 million for 2001. The Company expects to fund
its capital expenditures with cash generated by operations and the issuance of
commercial paper.     

DEBT
    
At September 30, 1998, CONSOL had total long-term debt of $430 million,
including current portion of long-term debt of $109 million. Such long-term debt
consisted of (1) an aggregate principal amount of $256 million of unsecured
notes which bear interest at rates ranging from 7.88% to 8.28% per annum and are
due at various dates between 1999 and 2007, (2) an aggregate principal amount of
$103 million of two series of industrial revenue bonds which were issued in
order to finance CONSOL's Baltimore port facility and bear interest at the rate
of 6.5% per annum and mature in 2010 and 2011, (3) an aggregate principal amount
of $3 million of variable rate notes due at various dates through 2001, (4) $28
million in advance royalty commitments, (5) an aggregate principal amount of $14
million of notes maturing at various dates through 2007 and (6) an aggregate
principal amount of $26 million of capital leases. An aggregate principal amount
of $109 million in long-term debt will come due during 1999. In addition, at
September 30, 1998, CONSOL had an aggregate principal amount of $105 million of
commercial paper outstanding which had maturities ranging up to 30 days and bore
interest at varying rates.     
    
CONSOL issued $600 million in commercial paper in November, 1998 in order to
fund the purchase of shares from DuPont Energy, a dividend of $60 million and
the acquisition of Rochester & Pittsburgh and the refinancing of certain
indebtedness incurred by Rochester & Pittsburgh. The commercial paper pays
interest at varying rates and will be retired in part with the net proceeds of
the offering. At November 30, 1998, there was $543 million principal amount of
commercial paper outstanding. CONSOL will retire outstanding commercial paper
with proceeds of the offering. After retiring the outstanding commercial 
paper, CONSOL believes that it will continue to be able to issue commercial
paper.     

CONSOL has a Senior Credit Facility available to it under which it may borrow up
to $700 million. At November 30, 1998, there were no borrowings outstanding
under the Senior Credit Facility. To date, CONSOL has used the Senior Credit
Facility to support the payment of its commercial paper. However, CONSOL could
borrow amounts under the Senior Credit Facility for other purposes. Borrowings
under this facility bear interest based on the London Interbank Offer Rate or
the Prime Rate at CONSOL's option. Funds may be borrowed for periods ranging
from one to 360 days, depending upon the interest rate selected by CONSOL.

CONSOL has not engaged in any hedging transactions since 1995.

STOCKHOLDERS' EQUITY AND DIVIDENDS
    
CONSOL had stockholders' equity of $303 million at December 31, 1997 and $427
million at September 30, 1998. CONSOL paid ordinary cash dividends of $80
million during each of 1995, 1996 and 1997. CONSOL paid a dividend of $60
million in November 1998 and a $20 million dividend in December 1998. CONSOL
also paid an extraordinary cash dividend to its stockholders of $380 million in
1997. The Board of Directors currently intends to pay quarterly dividends on the
common stock. It is expected that the first quarterly dividend will be $ per
share (a rate of  per share annually) and will be declared and paid in the third
quarter     

                                       32
<PAGE>
 
of 1999. Current outstanding indebtedness of CONSOL does not restrict CONSOL's
ability to pay cash dividends.


ACCRUALS FOR CERTAIN LONG-TERM LIABILITIES
    
CONSOL has accrued for the costs it will incur in the future to satisfy certain
obligations. CONSOL had accrued $2,484 million, $2,460 million, $2,433 million
and $2,466 million at December 31, 1995, 1996, 1997 and September 30, 1998 for
deferred credits and other liabilities. These accruals are chiefly comprised of
post retirement health care benefits, workers' compensation, pneumoconiosis
(black lung) benefits and costs associated with closing mines. These obligations
are unfunded. The accruals of these items are based on estimates of future
liabilities, which estimates are periodically reviewed in light of CONSOL's
experience, changes in mining plans and legislation and other developments.
Thus, from time to time, CONSOL's results of operations may be significantly
affected by changes to such deferred credits and other liabilities. See Notes 14
and 15 of the Notes to Consolidated Financial Statements.     
    
CONSOL provides medical and life insurance benefits to retired employees not
covered by the Coal Industry Retiree Health Benefit Act of 1992. Substantially
all of CONSOL's employees may become eligible for these benefits if they have
worked ten years and attained the age of 55. The associated plans are unfunded.
CONSOL had accrued $1,145 million, $1,144 million, $1,145 million and $1,289
million at December 31, 1995, 1996 and 1997 and September 30, 1998,
respectively. The net costs of maintaining CONSOL's post retirement benefits
plans were $47 million, $54 million, $61 million and $55 million during 1995,
1996, 1997 and the nine months ended September 30, 1998, respectively. CONSOL
used a 7.5% annual rate increase in per capita cost of covered health care
benefits in determining such costs for 1997. CONSOL had assumed that the rate of
such increases will gradually decline to 4.5% in 2003 and remain level
thereafter. An increase in the assumed health care cost trend rates by 1% in
each year would increase the accumulated post retirement benefit obligation at
December 31, 1997 by $85 million and increase the aggregate of the service and
interest cost component of net cost of maintaining CONSOL's post retirement
benefits plan for 1997 by $8 million.     
    
CONSOL is required to pay pneumoconiosis (black lung) benefits to eligible
employees and former employees and their dependents under the Black Lung
Benefits Act of 1969 and the Black Lung Benefits Revenue Act of 1977 and the
Black Lung Benefits Reform Act of 1977. CONSOL is also liable under various
state statutes for pneumoconiosis claims. CONSOL provides self-insured accruals
for present and future liabilities for such benefits and determines such
liabilities by employing the projected unit credit method. Under this method,
the costs determined by the actuarial study are amortized over the employees'
requisite service periods. CONSOL amortizes the actuarial gains and losses over
the remainder of the average service life of the employees, which approximates
15.4 years. CONSOL had accrued $518 million, $518 million, $511 million and $496
million for such benefits at December 31, 1995, 1996, 1997 and September 30,
1998. The cost of providing such benefits was $6 million, $12 million and $4
million during 1995, 1996, 1997. The impact of these costs has not been
significant for the 1998 Period. Actual claims paid by CONSOL could change
significantly if current legislation is amended or if new legislation is
enacted. See "Regulation--Employee and Retirement Benefits--Black Lung
Legislation" and Note 14 of Notes to Consolidated Financial Statements.     
    
CONSOL estimates and accrues for costs associated with closing mines and the
perpetual care of mines over the productive life of mines on a
units-of-production basis. CONSOL had accrued $246 million, $244 million, $250
million and $286 million at December 31, 1995, 1996, 1997 and September 30, 1998
for such costs.     
    
CONSOL accrues for workers' compensation claims resulting from traumatic
injuries based on historical claims rates and periodically adjusts these
estimates based on the estimated costs of claims made. CONSOL had accrued $225
million, $215 million, $211 million and $248 million at December 31, 1995, 1996,
1997 and September 30, 1998 for such costs.

INFLATION
    
Inflation in the United States has been relatively low in recent years and did
not have a material impact on CONSOL's results of operations for the nine months
ended September 30, 1998 or the years ended December 31, 1995, 1996 or 
1997.     


IMPACT OF YEAR 2000 ISSUE
    
The year 2000 issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Any of CONSOL's computer
programs or hardware that have date-sensitive software or embedded chips may
recognize a date using "00" as the year 1900 rather than the year 2000. The
failure to correct any such programs or hardware could result in system failures
or miscalculations causing disruptions of operations, including, among other
things, a temporary inability to process transactions, send invoices or engage
in similar normal business activities. Based on recent assessments, CONSOL has
determined that it will be required to modify or replace some portions of its
software, and, to a lesser extent, its hardware so that those systems will
properly utilize dates beyond December 31, 1999. CONSOL believes that with
modification and replacement of existing software and hardware, the year 2000
issue can be substantially mitigated. However, if such modifications and
replacements are not made, or are not completed on a timely basis, which CONSOL
currently does not anticipate, the year 2000 issue could have a material impact
on the operations of CONSOL.     
    
CONSOL's plan to resolve year 2000 issues involves four phases: assessment,
remediation, testing and implementation. In September 1997, CONSOL formed a
committee to address this issue. The committee has completed its assessment of
all material information technology systems that would be affected by the year
2000 issue if not modified and has initiated a program to modify or replace
portions of its software so that CONSOL's computer systems will function
properly in the year 2000 and thereafter. To date, CONSOL is 50% complete on the
remediation and testing phase of the systems. CONSOL expects software
reprogramming and replacement, testing and implementation to be completed by the
second quarter of 1999.     
    
CONSOL is in the process of assessing its operating equipment that uses
microprocessors to determine the extent that they are at risk for year 2000
problems. This equipment includes coal mining, processing and loadout equipment.
The remediation of operating equipment depends primarily on the manufacturers of
that equipment for modifications. CONSOL is also in the process of assessing the
extent to which its suppliers of other products and services will be able to
supply CONSOL through the year 2000. CONSOL has initiated formal communications
with all of its significant equipment vendors and other suppliers. CONSOL has
not obtained timetables of expected completion dates of modification, testing
and implementation from all of the vendors and suppliers. CONSOL does not
control its suppliers and vendors, but is attempting to have such timetables
submitted in the first quarter of 1999. The effect on CONSOL's operations of not
having these systems remediated, while not estimable at this time, could be
significant.     
    
CONSOL conducts transactions that interface directly with systems of suppliers
and customers. There is no guarantee that the systems of other companies on
which CONSOL's systems rely will be timely converted and would not have an
adverse effect on CONSOL's systems. Furthermore, there can be no assurance that
CONSOL's suppliers will not experience material business disruptions that could
affect CONSOL as a result of the year 2000 problem. CONSOL plans to complete
communications with important suppliers and customers, which do not have system
interfaces, as to their year 2000 readiness in the first quarter of 1999. The
communications to date from such third parties to CONSOL's inquiries do not
indicate that these third parties expect, at this time, to be non-compliant by
the year 2000 based on their progress to date. However, the inability of a
substantial number of third parties to complete their year 2000 resolution
process could materially impact CONSOL. For example, the failure to be year 2000
compliant by banks with whom CONSOL has material banking relationships could
cause significant disruptions in CONSOL's ability to make     

                                       34
<PAGE>
 
payments, deposit funds and make investments, which could have a material
adverse effect on CONSOL's financial condition.
    
CONSOL is utilizing both internal and external resources to reprogram or
replace, test and implement the software and operating equipment for year 2000
modifications. The total cost of the year 2000 project is estimated to be less
than $2 million and is being expensed as incurred and funded through operating
cash flows. In 1998, CONSOL expects to expense $539,000 related to all phases of
the year 2000 project.     
    
CONSOL has not established contingency plans in case of failure of its
information technology systems since it expects to have its material systems in
place by the second quarter of 1999. In connection with CONSOL's assessment of
third party readiness and operating equipment, in the first quarter of 1999
CONSOL will evaluate the necessity of contingency plans based on the level of
uncertainty regarding such compliance. In the event CONSOL's intermediaries or
vendors do not expect to be year 2000 compliant, CONSOL's contingency plan may
include replacing such intermediaries or vendors or conducting the particular
operations itself.     
    
CONSOL plans to complete the year 2000 modifications are based on management's
best estimates, which were derived utilizing numerous assumptions of future
events including the continued availability of certain resources, and other
factors. Estimates on the status of completion and the expected completion dates
are based on progress to date compared to the timetable established by its year
2000 committee. CONSOL has not employed the services of independent contractors
to verify CONSOL's assessment and estimates related to the year 2000 problem.
There can be no guarantee that these estimates will be achieved and actual
results could differ materially from these plans. Specific factors that might
cause such material differences include, but are not limited to, the
availability and cost of personnel trained in this area, the ability to locate
and correct all relevant computer codes and similar uncertainties.     
    
CONSOL believes that it is difficult to fully assess the risks of the year 2000
issue due to numerous uncertainties surrounding the issue. Management believes
that the primary risks are external to CONSOL and relate to the year 2000
readiness of customers, suppliers, transportation suppliers such as railroads,
barge lines, terminal operators, ocean vessel brokers, and others. The inability
of CONSOL or such third parties to adequately address the year 2000 issues on a
timely basis could result in a material financial risk, including loss of
revenue, substantial unanticipated costs and service interruptions. Accordingly,
CONSOL plans to devote the resources it concludes are appropriate to address all
significant year 2000 issues in a timely manner.     


RECENT ACCOUNTING PRONOUNCEMENTS

In June 1997, SFAS No. 130, "Reporting Comprehensive Income" was issued which
establishes new rules for the reporting and display of comprehensive income and
its components. CONSOL adopted this statement for the year ending December 31,
1998. CONSOL has no significant items of other comprehensive income.

In June 1997, SFAS No. 131, "Disclosure about Segments of an Enterprise and
Related Information" ("SFAS 131) was issued which establishes standards for
disclosure about operating segments in annual financial statements and selected
information in interim financial reports. It also establishes standards for
related disclosures about products and services, geographic areas and major
customers. This statement supersedes SFAS No. 14 "Financial Reporting for
Segments of a Business Enterprise." The new standard requires that comparative
information from earlier years be restated to conform to requirements. CONSOL
adopted this standard for 1997.

In February 1998, SFAS No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits" was issued which improves and standardizes disclosures
by eliminating certain existing reporting requirements and adding new
disclosures. The statement addresses disclosure issues only and does not change
the measurement of recognition provisions specified in previous statements. The
statement supersedes 

                                       35
<PAGE>
 
the disclosure requirements of SFAS No. 87, "Employer's Accounting for
Pensions," SFAS No. 88, "Accounting for Settlements and Curtailments of Defined
Benefit Pension Plans and for Termination Benefits" and SFAS No. 106,
"Employers' Accounting for Postretirement Benefits Other than Pensions." CONSOL
intends to adopt this statement for the year ending December 31, 1998.

In June 1998, SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities" was issued which establishes accounting procedures for derivative
instruments including certain derivative instruments embedded in other contracts
and hedging activities. This statement amends SFAS No. 52, "Foreign Currency
Translation" to permit special accounting for a hedge of a foreign currency
forecasted transaction with a derivative. It supersedes SFAS No. 80, "Accounting
for Futures Contracts, SFAS No. 105, Disclosure of Information about Financial
Instruments with Off-Balance-Sheet Risk and Financial Instruments with
Concentrations of Credit Risk", SFAS No. 119 "Disclosure about Derivative
Financial Instruments and Fair Value of Financial Instruments." It also amends
SFAS No. 107, "Disclosure about Fair Value of Financial Instruments" to include
the disclosure provisions about concentration of credit risk from Statement 105.
CONSOL intends to adopt this statement for the year ending December 31, 1998. No
effect from this adoption is anticipated.

                            COAL INDUSTRY OVERVIEW


Coal is one of the world's major energy sources. The International Energy Agency
estimates that nearly 20% of the world's total primary energy supply came from
coal in 1996. In most parts of the world, coal is primarily used for the
generation of electricity. World-wide, coal combustion accounted for 37% of the
generation of electricity in 1996. In the United States, coal combustion
accounted for 57% of electricity generation in 1997.

The major coal producers in the world are China, the United States, Russia,
Ukraine, India, Australia and South Africa. More than 60 countries produce coal.
The United States has the largest reserve base, with an estimated 29% of the
world's recoverable bituminous and subbituminous coal reserves, followed by
Russia, China, India, South Africa and Australia.


U.S. COAL MARKETS

Production of coal in the United States has increased from 434 million tons in
1960 to 1.1 billion tons in 1997. The following table shows actual consumption
of U.S. produced coal during 1996 and 1997 and projected consumption through
2015.

GENERATION OF ELECTRICITY

Coal is the predominant fuel used in the generation of electricity. Over the
past 20 years, generators of electricity have increased consumption of coal from
less than 500 million tons per year in 1977 to almost 900 million tons in 1997.
Coal's share of the fuel market for electricity generation has risen from 46% to
57% 

                                       37

during that period. The increase in consumption was due in part to changes
in attitudes toward fuel supply security following the Arab oil embargoes during
the 1970s. More important, coal has a low delivered cost relative to other
competing fuels. The following table shows a comparison of the average
generating costs of electricity for each primary fuel.

On average, coal-fired electricity generation is less expensive than generation
from natural gas or nuclear power. Hydro-electric power is inexpensive but
cannot grow due to a lack of suitable new dam sites.
    
RDI expects generators of electricity to increase their demand for coal as
demand for electricity increases. Because coal-fired generation is used in most
cases to meet base-load requirements, coal consumption has generally grown at
the pace of growth in demand for electricity. The base-load requirement of a
power generator is the amount of power that is required 24 hours a day. This is
compared to peak requirements that only occur at times during a day when
electricity demand is at its greatest.     

The following table shows fuel source comparisons for the generation of
electricity in terms of kilowatts generated.

EXPORTS
    
Current world seaborne trade in hard coal is about 480 million tons, with about
61% used to generate heat and produce steam, and about 39% used in steel-making
processes. Of the world's coal producing countries, only the United States,
Australia and South Africa are significant exporters. Prior to 1984, the United
States was the world's leading exporter of coal, but in the past 15 years that
role has diminished and traditional markets for     

                                       38
<PAGE>
 
U.S. coal exports have changed. In general, the United States is a swing
producer of coal for international markets. Higher labor costs and
transportation costs in the United States tend to make U.S. coals less
competitive when ample supplies of coal from other producing areas are
available. When supplies are restricted, for example because of a strike of
workers in a producing country, U.S. coal tends to fill the gap because of the
ability of U.S. producers to ship large amounts of coal on short notice. The
quality of U.S. coals, particularly the heat content, ash and coking
capabilities of Appalachian coals, and the well developed transportation
infrastructure in the East, are advantages for the United States. CONSOL
believes that its high-Btu, low ash coals from northern Appalachia and CONSOL's
control of a major export terminal at Baltimore position it to take advantage of
steam coal market opportunities overseas when they occur.

The U.S. Department of Energy estimates that the United States exported 83.5
million tons of coal in 1997. The most coal ever exported by the United States
was in 1981 when exports reached 112.5 million tons. Since 1990, exports have
averaged 90.7 million tons per year. More than 98% of the coal exported by the
United States is bituminous coal, most of which is mined in northern and central
Appalachia. The remainder of the coal exported is anthracite and lignite. In
1997, Canada (14.5 million tons), Japan (7.9 million tons), and Brazil (7.5
million tons) were the three largest purchasers of U.S. coal overseas.
    
Metallurgical coal historically has been the principal type of coal exported
from the United States. In 1997, more than 63% of the coal exported was
bituminous, metallurgical-grade coal used in steel making. The remainder of the
coal was used for the generation of electricity, cement making and other
industrial processes. Major international purchasers of U.S. metallurgical coals
are Brazil, Canada, Japan, Italy, The Netherlands, Belgium and France.     
    
CONSOL expects growth over the long term in steel making and metallurgical coal
consumption in Brazil, India, Korea and Taiwan to offset a slight decline in
metallurgical coal use in Europe. CONSOL believes that increased steel
production in these countries will lead to increased metallurgical coal
consumption. Europe will continue to be a primary market for U.S. metallurgical
coal because of the transportation advantage U.S. coals have over coals from
Canada or Australia. In addition, aging European coke ovens increasingly will
need high quality, low-expansion coals which produce high carbon content and low
porous structure coke. These features are common in CONSOL's low-volatile
metallurgical coal produced in Virginia. In addition, CONSOL expects its premium
low-volatile metallurgical coal to continue to play an important role in the
coking coal blends of the future. These coals enhance the strength of the coke
produced. This is particularly important to large blast furnaces operated with
low coke rates and with high pulverized-coal, oil or gas injection rates.    

COAL IMPORTS
    
Coal imports into the United States represent a small percentage of the total
U.S. market for coal. In 1997, total consumption of coal in the United States
was 1,021.2 million tons while imports of coal from overseas were 7.4 million
tons, or 0.7%. The largest exporter of coal to the United States was Colombia
with 3.0 million tons in 1997. Imported coal typically competes only in coastal
markets in the eastern United States.     


COAL PRODUCTION

U.S. coal production was a record 1,088.6 million tons in 1997. During 1996, the
most recent year for which complete data is available, bituminous coal accounted
for 59% of production, subbituminous coal accounted for 32%, lignite accounted
for 8% and anthracite accounted for 1%.

U.S. coal production increased 3.5% from 1990 to 1996, while the number of
operating mines declined 44.5% during the same period. In part, this reflected a
shift from smaller, high-cost operations to larger, more efficient,
technologically advanced, lower-cost operations. In particular, the production
attributable to large, capital intensive underground mines in the East and large
surface mines in the Powder River Basin in the West 

                                       40

has grown. The cost structure of these mines has contributed to a steady decline
in steam coal prices that has allowed coal to maintain more than half of the
market in the United States for fuel used in generating electricity.

MINING METHODS

Coal is mined by underground or surface methods depending upon several factors,
including the location of the coal seam and the geology of the surrounding area.
In general, coal that is more than 200 feet below the surface is mined by
underground, or "deep" mining methods. Seams closer to the surface are extracted
by surface mining.

Underground mining accounted for 39% of total U.S. coal production in 1996.
There are two principal methods of underground mining: continuous mining, which
accounted for 45% of underground coal produced in 1996, and longwall mining,
which accounted for 47% of underground coal produced in 1996. In continuous
mining, coal is mined by the room-and-pillar system. This involves the
excavation of a series of "rooms" into the coal seam, leaving "pillars" or
columns of coal to help support the mine roof. Mining conditions in certain
areas may allow the coal pillars to be extracted during the "retreat" phase of
mining. A mining machine called a continuous miner tears at the coal in the
seam. Typically, the coal is loaded onto shuttle cars which transport the coal
to a conveyor belt or to rail cars for transport to the surface. The use of
shuttle cars to transport coal from the "section" where mining is taking place
to the belt or rail transportation system, is a bottleneck in the production
cycle and results in lost mining time at the coal seam while the continuous
miner waits for shuttle cars to remove the coal from the working area.

Where geology is favorable, the most efficient method of underground extraction
of coal is with longwall mining systems. With these systems, two sets of
parallel "entries" up to 10,000 feet in length are excavated by continuous
miners on either side of a block of coal to be mined by the longwall equipment.
The entries are joined together at the far end by crosscuts in the coal. The
block of coal thus outlined is called a "panel," and the 1000-1200 foot
dimension of the panel (hence the name "longwall") is referred to as the "face"
where the longwall mining machine will begin cutting coal. A rotating shearer on
a mining machine moves back and forth across the width of the face, cutting and
transporting coal from the face in one operation. The longwall machine has its
own moveable electro-hydraulic roof supports that are advanced down the length
of the block of coal as the shearer cuts the coal away. This method of mining
removes all the coal in the panel without leaving coal in place for roof
support. Mining by longwall methods has revolutionized underground mining
operations in the last 20 years. Over that period, the share of coal mined
underground by longwall mining machines has increased from less than 10% to 47%.

Surface mining consists of the following operations: removal of the covering
layer of rock and soil, called overburden, extraction of the coal using power
shovels, which load the coal into trucks to transport the coal from the "pit,"
backfilling the excavation with earth, and restoring the site to its approximate
original vegetation and appearance. In smaller surface mines, bulldozers and
front-end loaders are often used to remove overburden. Front-end loaders can
also be used to load coal.

After mining, coal often is prepared for shipment in a preparation plant. This
facility utilizes sizing, gravity, centrifugal force and chemical baths to
separate the coal from the non-combustible rock material. This cleaning process
upgrades the quality and heat value of the coal by removing or reducing pyritic
sulfur deposits, rock, clay and other non-combustible, ash producing material.
After cleaning, coal is transported to the customer immediately or stored on the
ground or in large, concrete silos for transportation to customers later.

COAL PRODUCING REGIONS

Coal is mined from coalfields throughout the United States, with the major
production centers located in northern Appalachia, central Appalachia, the
Illinois Basin, the Powder River Basin and in other western coalfields.


[Map of the U.S. indicating the locations of major coal basins]

NORTHERN APPALACHIA

Medium- and high-sulfur coal is found in the northern Appalachia coalfields of
western Pennsylvania, southeastern Ohio and northern West Virginia. Production
in the region was approximately 156 million tons in 1997, up from 147 million
tons in 1996. In 1997, 121 million tons were sold to electric utilities. Coal
production has increased slightly in recent years and production has shifted
from high-cost, inefficient, low-volume operations to lower cost, more
efficient, high-volume operations. As a result, much of the production in this
region is concentrated in a few highly productive longwall mining operations in
southwestern Pennsylvania and northern West Virginia. The coal from northern
Appalachia has a heat content ranging from 12,500 to 13,000 Btus per pound and
generally has medium- to high-sulfur content.

Coal producers in southwestern Pennsylvania enjoy strong competitive advantages
for markets within the state, due to the proximity of many power plants to the
coal producing region. Power plants located along the Monongahela and Ohio
rivers have access to a wide variety of coals, particularly those produced in
West Virginia.

Two other markets in which southwestern Pennsylvania and northern West Virginia
coal producers enjoy a transportation advantage are utility companies with
plants in New York and Maryland that can burn medium- to high-sulfur coal and
are served by railroads. Railroads also offer this coal good access into Ohio
and other Great Lake states.

CENTRAL APPALACHIA

The central Appalachia region includes coalfields in eastern Kentucky,
southwestern Virginia and central and southern West Virginia. Production in
central Appalachia was 288 million tons in 1997 compared with 279 million tons
in 1996. In 1997, 175 million tons produced in central Appalachia were sold to
electric utilities principally in the southeast United States. Central
Appalachia operations also sell to the export market and to industrial
customers. Geologic conditions in central Appalachia led to the creation of over
100 significant coalbeds, 60 of which currently are mined. A variety of mining
techniques are used as seams are found on mountaintops and below valley floors.
The coal from central Appalachia has an average heat content of 12,500 Btus per
pound and generally has low-sulfur content.

The southeast United States has significant potential for the growth of coal
demand. Much of the demand growth in the 1980s was attributable to new
coal-fired power plants. At the same time, however, nuclear plants were being
brought on-line by some utilities. Thus, some utilities were reducing the use of
existing coal plants because of new nuclear plants while other utilities were
increasing coal burn because of new plants. The result is that some utilities
have excess coal-fired capacity despite the growth of electricity demand over
the past ten years.

ILLINOIS BASIN

The Illinois Basin is located under most of Illinois, western Indiana and
western Kentucky. Production in the basin was 112 million tons in 1997 and in
1996. In 1997, 103 million tons were sold to electric utilities. With the
depletion of surface minable reserves, mining today is predominantly done
underground. Coal production in the area has experienced significant
consolidation in the past several years. The Illinois Basin is a declining

                                       42
<PAGE>
 
production center due to the region's relatively high-sulfur coal and
competition from lower-sulfur western coal. Production in the Illinois Basin
peaked at 141 million tons in both 1984 and 1990. Since 1990, production has
decreased by 20%. In 1996, production stabilized in several of the Illinois
Basin's sub-regions, including central Illinois, due to stabilized demand and
limited capacity. The coal from the Illinois Basin has a heat content ranging
from 10,000 to 12,000 Btus per pound and generally has medium- to high-sulfur
content.

The principal utility markets for Illinois Basin coal are the rail- or
truck-served plants located within the coal producing states of Illinois,
Indiana, and Kentucky that comprise the region and in the neighboring states of
Missouri, Iowa, Kansas, and Wisconsin. Barge-served plants on the lower Ohio,
Cumberland, Tennessee and Mississippi rivers, as well as a few plants in Florida
and along the Gulf Intracoastal waterway are also important markets.

The close proximity of the Illinois Basin to the mouth of the Ohio, Tennessee
and Cumberland rivers and the Port of New Orleans provides the region with
several advantages in serving its primary markets when compared to Northern
Appalachia or other high sulfur producing regions. A shorter transit time for
western Kentucky and southern Illinois coal to these markets minimizes transit
costs.

POWDER RIVER BASIN

The Powder River Basin is located in northeastern Wyoming and southeastern
Montana. Production in 1997 was 306 million tons compared with 299 million tons
in 1996. In 1997, 306 million tons were sold to electric utilities. Quality
varies between lignite and subbituminous coals, with current production of
subbituminous coal averaging 9,100 Btus per pound and 0.5% sulfur in Montana, to
8,600 Btus per pound and 0.3% sulfur in Wyoming.

WESTERN BITUMINOUS COAL REGIONS

The western bituminous coal regions include the Hanna Basin in Wyoming, the
Uinta Basin of northwestern Colorado and Utah, the Four Corners Region in New
Mexico and Arizona and the Raton Basin in southern Colorado. Production in 1997
was 116 million tons compared with 110 million tons in 1996. In 1997, 95 million
tons were sold to electric utilities. These regions produce high quality,
low-sulfur steam coal for selected markets in the region, for export through
West Coast ports and for shipments to some Midwestern power plants for which
Powder River Basin's subbituminous coals are not suitable. Coal from the western
bituminous coal region has a heat content ranging from 9,000 to 11,500 Btus per
pound and generally has low-sulfur content.

COAL CHARACTERISTICS

There are four types of coal: anthracite, bituminous, subbituminous and lignite.
Each has characteristics that make it more or less qualified for different end
uses. In general, coal is characterized by end use as either "steam coal" or
"metallurgical coal." Steam coal is used by utilities for electricity generation
and by industrial activities to produce steam, electricity, or both.
Metallurgical coal is converted into coke, which is used in the production of
steel. Heat value, sulfur content and transportation costs are the most
important variables in the marketing of steam coal.

HEAT VALUE

The heat value of coal is commonly measured in British thermal units, or Btus.
Coal found in the eastern and midwestern regions of the United States tends to
have a heat content ranging from 10,000 to 14,000 Btus per pound. Most coal
found in the western United States yields less than 11,000 Btus per pound. By
comparison, 

                                       43
<PAGE>
 
one barrel of crude oil contains between 4.8 million and 5.4 million Btus and
one cubic foot of natural gas contains between 950 and 1,050 Btus.

Anthracite coal has a heat content as high as 15,000 Btus per pound. A limited
amount of anthracite deposits is located primarily in northeastern Pennsylvania,
and is used primarily for industrial and home heating purposes.

Bituminous coal has a heat content that ranges from 10,500 to 14,000 Btus per
pound. This coal is located primarily in Appalachia, the midwestern United
States, Colorado, Arizona and Utah, and is the type most commonly used for
electric power generation in the United States. Bituminous coal is used for
utility and industrial steam purposes, and as a feedstock for coke.

Subbituminous coal has a heat content that ranges from 7,800 to 9,500 Btus per
pound. Most subbituminous reserves are located in Montana, Wyoming, Colorado,
New Mexico, Washington and Alaska. Subbituminous coal is used almost exclusively
by electric utilities and some industrial consumers.

Lignite has a heat content that generally ranges from 6,500 to 8,300 Btus per
pound. Major lignite operations are located in Texas, North Dakota, Montana and
Louisiana. Lignite is used almost exclusively in power plants located adjacent
to or near such mines because any significant transportation costs, coupled with
mining costs, would render its use uneconomical.

SULFUR

The sulfur content of a coal deposit can vary from seam to seam and within each
seam. When coal is burned, it produces sulfur dioxide, a regulated pollutant,
the amount of which varies depending upon the chemical composition and the
concentration of sulfur in the coal. Low-sulfur coal has a variety of
definitions, but it generally refers to coal with a sulfur content of 1% or less
by weight.

During the past two decades, air quality laws have created some market
advantages for lower-sulfur coals by imposing restrictions on the amount of
sulfur dioxide that can be released into the atmosphere when coal is burned. The
restrictions usually require high-sulfur coal users to install scrubbers or to
buy pollution allowances under the Clean Air Act. CONSOL believes that future
demand for coal will be influenced by the heat content of the coal and by the
proximity of the coal to major electricity generating stations more than by the
sulfur content of the coal. See "Business?Competitive Strengths?High-Quality,
Strategically-Located Reserve Base."

ASH

Ash is the inorganic residue remaining after combustion of coal. As with sulfur
content, ash content varies from seam to seam and within seams. Ash content is
an important characteristic of coal because power plants must handle and dispose
of ash following combustion.

MOISTURE

Moisture content of coal varies by the type of coal, the region where it is
mined and the location of coal within a seam. In general, high moisture content
decreases the heat value and increases the weight of the coal, making it more
expensive to transport.

COKING PROPERTIES OF METALLURGICAL COAL

When some types of coal are super-heated in the absence of oxygen, they form a
hard, dry, caking product called coke, which is chiefly used in the steel
production process as a fuel and reducing agent to smelt iron ore in a blast
furnace.

COST STRUCTURE

COAL PRICES

Coal prices vary dramatically among coals and are affected primarily by the
marginal cost of production and transportation costs to the customer. Factors
that influence coal prices are geological characteristics (such as seam
thickness, overburden ratios and depth to underground reserves), transportation
costs, regional coal production capacity relative to demand and coal quality
characteristics including heat value, ash, moisture and sulfur content.

Industrial coal generally costs more to produce and is shipped in smaller
volumes than steam coal from the same region used by generators of electricity.
As a result, industrial coal's prices are $3 to $5 dollars per ton higher.
Metallurgical coal, with higher carbon content and lower ash content generally
costs more to mine and typically has prices $4 to $10 per ton higher than steam
coal produced from the same region. Even higher prices are paid for premium
metallurgical coal.

The following table summarizes steam coal prices for the generation of
electricity by supply region.

TRANSPORTATION

Coal for domestic consumption generally is sold at the mine and transportation
costs are normally borne by the purchaser. Export coal is usually sold at the
loading port. Coal producers are responsible for shipment to the export
coal-loading facility and the buyer pays the ocean freight. Coal for electricity
generation is purchased on the basis of its delivered cost per million Btus.
Most utilities arrange long-term shipping contracts with rail or barge companies
to assure stable delivered costs.

Transportation is often a large component of the buyer's cost. Although the
customer pays the freight, transportation cost is still important to coal mining
companies because the customer may choose a supplier largely based on the cost
of transportation. According to RDI, in 1995, transportation costs represented
69%, 28% and 25% of the overall delivered cost of coal produced in the western
United States, eastern United States and midwestern United States.

According to the National Mining Association in 1997, approximately 77% of all
U.S. coal was shipped by rail or barge, making these modes the keys to domestic
coal distribution. Trucks and overland conveyors are used to haul coal over
shorter distances. Lake carriers and ocean carriers transport coal to export
markets. Some domestic coal is shipped over the Great Lakes to domestic markets.
Railroads move more coal than any other commodity, and in 1996 coal accounted
for 22% of total U.S. rail freight revenue and 44% of total rail freight
tonnage.


DEREGULATION OF THE ELECTRIC UTILITY INDUSTRY
    
In October 1992, the National Energy Policy Act was signed in the United States,
giving wholesale suppliers access to the transmission lines. In April 1996, the
Federal Energy Regulatory Commission issued orders establishing rules providing
for open access to electricity transmission systems, thereby encouraging
competition in the generation of electricity. While broad deregulation
legislation is still being considered at the federal level, a number of states
have taken significant deregulation initiatives as provided for by the Federal
Energy Regulatory Commission.     

Deregulation of the electric utility industry, if and where implemented, would
enable industrial, commercial and residential customers to shop for the lowest
cost supply of power and the best available service. This fundamental change in
the industry is expected to compel electric utilities to be more aggressive in
developing and defending market share, to be more focused on their cost and
pricing structure, and to be more flexible in reacting to changes in the market.

CONSOL believes that the move toward a competitive market for electricity should
prove beneficial to coal demand. According to RDI, 21 of the 25 lowest cost
electric generating stations are coal fired. As deregulation occurs and
competition among generators increases, electricity generators will become
increasingly sensitive to fuel costs because such costs typically represent
about 78% of the variable cost of generating electricity from fossil fuels.

OVERVIEW

CONSOL ranks among the largest coal companies in the United States based upon
total revenue, net income and operating cash flow. CONSOL is the largest U.S.
producer of high-Btu bituminous coal, the largest coal producer east of the
Mississippi River, the largest producer of coal from underground mines and the
largest U.S. exporter of coal to international markets. Production in 1997
totalled 73 million tons. CONSOL accounted for 7% of total domestic tons
produced and for 12% of tons produced in the eastern United States during 1997.
CONSOL's consistent financial performance has enabled it to establish a strong
history of cash generation and dividend payments.

In 1997, CONSOL sold 68% of the tons of coal it produced directly to domestic
electricity generators, 16% to domestic industrial customers, domestic steel
mills and trading companies and 16% directly to export markets. The electricity
generating market is, by far, the most important market for U.S. coal producers
and for CONSOL, and coal is the fuel of choice for base-load power plants in the
United States. In 1997, coal was used to generate 57% of the electricity in the
United States.

CONSOL's proximity to generating plants, access to low-cost transportation,
favorable geologic conditions for mining and the high-Btu content of its coal
enable it to provide fuel to electricity generators at low delivered cost.
CONSOL's large, highly mechanized eastern mines are located near major
electricity generators in the northeastern, Mid-Atlantic, southeastern and
midwestern United States. In 1997, almost 40% of CONSOL's coal moved on inland
waterways, the mode of transport considered the most cost-effective for bulk
commodities. Approximately 65% of CONSOL's reserves consist of high-Btu coal.

CONSOL had 4.8 billion tons of proved and probable reserves at December 31,
1997, the second largest among U.S. coal producers. Reserves are located in
northern Appalachia (52%), central Appalachia (13%), the midwest (21%) and in
the western United States and Canada (14%). The size, quality and strategic
location of CONSOL's reserves provide a basis for the expansion of many existing
mines and for new mine development.
    
CONSOL operated 24 mining complexes at December 31, 1997. The Company added
three complexes in September 1998 by acquiring Rochester & Pittsburgh. Two
complexes, Holden and Twin Branch, were exchanged in November 1998, for the
Vesta coal reserves located in southwestern Pennsylvania. CONSOL uses
high-extraction longwall technology at 14 of its mines and leads the industry in
the deployment of longwall systems. The mines operating these advanced mining
systems accounted for approximately 84% of the coal mined by CONSOL in 1997.
CONSOL's ability to source coal from its multiple longwall mines provides it
with great flexibility in meeting customer fuel requirements.
CONSOL can expand production at longwall mines at very low incremental 
cost.     

    
CONSOL'S HISTORY     
    
CONSOL Energy Inc. was organized as a Delaware corporation in 1991. CONSOL is a
holding company for 64 direct and indirect wholly owned operating subsidiaries,
including Consolidation Coal Company and CONSOL Inc. Consolidation Coal Company
is CONSOL'S principal operating subsidiary and CONSOL Inc. is CONSOL'S direct
holding company subsidiary that provides executive, management and
administrative services.     

                                       47
<PAGE>
 
    
CONSOL'S earliest predecessor, Consolidation Coal Company, was formed on March
9, 1860 with the merger of several small western Maryland coal holdings. Formal
incorporation was delayed until April 19, 1864 because of the Civil War. By
1927, Consolidation Coal Company had become the largest bituminous coal producer
in the United States. Consolidation Coal Company merged with Pittsburgh Coal
Company in 1945 to form the then largest coal company in the United States.
During the next 20 years, Consolidation Coal Company continued to grow through
acquisitions. In 1966, Continental Oil Company, a vertically integrated
petroleum company, acquired Consolidation Coal Company. E.I. du Pont de Nemours
and Company acquired Conoco in 1981. In 1991, RWE A.G., through its direct and
indirect wholly owned subsidiaries Rheinbraun A.G. and Rheinbraun U.S. GmbH,
purchased 50% of our common stock. RWE A.G. is a leading international
energy-based industrial conglomerate headquartered in Germany and is the fifth
largest industrial group in Germany based on annual sales. DuPont held its
remaining 50% interest in our common stock through DuPont Energy Company, its
wholly owned subsidiary. In November 1998, CONSOL purchased shares of its common
stock from DuPont Energy. After the purchase, and before this offering,
Rheinbraun A.G. and Rheinbraun U.S. GmbH together owned approximately 94% and
DuPont Energy owned approximately 6% of the outstanding shares of common 
stock.     

    
MINING METHODS     
    
CONSOL mines coal using both underground and surface mining methods. In 1997,
94% of CONSOL's production came from underground mines and 6% from surface
mines. The percentage of coal produced by surface mines has declined in recent
years because several CONSOL surface mines have depleted their mineable
reserves, and because production from existing underground mines has increased.
Nevertheless, CONSOL maintains engineering expertise in both mining 
methods.     
    
Where the geology is favorable and where reserves are sufficient, CONSOL employs
longwall mining systems in its underground mines. In 1997, 84% of CONSOL's
production came from mines equipped with longwall mining systems. Underground
mines equipped with longwall systems are highly mechanized, capital intensive
operations. These mines have a low variable cost structure compared with other
types of mines and can achieve high productivity levels compared with other
underground mining methods. Because CONSOL has substantial reserves readily
suitable to these operations, and because of their existing cost structure,
these longwall mines can increase capacity at low incremental cost.     
    
CONSOL operates approximately 25% of the U.S. longwall mining systems. Because
of the high production levels of these mining systems, which CONSOL uses at 14
of its mines, it operates seven of the 20 largest underground mines east of the
Mississippi River. The following table ranks the 20 largest underground mines in
the United States by tons of coal produced in 1997.

CONSOL's Research and Development Department has worked on a number of advances
that have enhanced longwall mining methods. CONSOL has developed proprietary
automation software that allows the shearer to guide itself in the coal seam,
reducing incursions into the rock above and below the seam, thus improving
initial coal quality and improving cutting bit life. The Research and
Development Department has also developed methods for automating shield advances
as mining progresses, which improves overall system efficiency. The Research and
Development Department has done geotechnical studies on pillar design that have
allowed continuous miners to advance more quickly and at lower cost when
developing the panels in advance of longwall mining. CONSOL's Research and
Development Department has developed several technological advances that allow
coal to be moved in more continuous fashion from the coal face, thus improving
utilization for the mining machinery, resulting in lower costs and higher
productivity. See "Business?Research and Development."

The calculation of the compound amount growth rate for the Shoemaker and VP 8
mines does not include periods during which such mines were shutdown. The
calculation for the McElroy mine excludes 200,000 tons of coal mined in
connection with construction activities.     

With the exception of Dilworth, VP 3 and Powhatan No. 4, these mines have the
potential to further expand production through investment in various projects to
debottleneck the coal mine or by instituting continuous work schedules to
maximize utilization of existing equipment. With the exception of Dilworth, VP 3
and Powhatan No. 4, these mines all have access to extensive, CONSOL-controlled
reserves to support expansion in capacity at low incremental cost.

According to an RDI database, CONSOL operated ten of the top 20 most productive
underground mines in 1997, in terms of tons per man day produced, based on an
analysis of production of large eastern U.S. underground mines (with production
greater than 3.0 million tons).

CONSOL.

MINING OPERATIONS
    
CONSOL currently operates 25 mining complexes. At September 30, 1998, CONSOL
operated a total of 27 mining complexes, including a 50% interest in a surface
mine in Alberta, Canada, all located in North America. In November 1998, CONSOL
exchanged the Holden Complex and the Twin Branch Complex with the A.T. Massey
Coal Company for the Vesta coal reserves located in southwestern Pennsylvania.
The exchange of properties reduced the number of mining complexes to 25.     

All of CONSOL's mining complexes are underground operations except the Mahoning
Valley and Cardinal River mines which employ only surface mining techniques. The
Mill Creek complex employs a combination of underground and surface mining
systems. Mining machinery used in all of CONSOL's underground mines is powered
by electricity.

Coal is transported from CONSOL's mining complexes to customers by means of
railroad cars, river barges, trucks, conveyor belts or a combination of these
means of transportation. The McElroy and Robinson Run mines transport coal to
customers by conveyor belt. The McElroy, Shoemaker, Dilworth, Powhatan No. 4,
Humphrey, Mahoning Valley and Ohio No. 11 complexes ship coal to customers by
means of river barges. Trucks are used to transport coal from Loveridge,
Blacksville, Powhatan No. 4, Rend Lake, Keystone, Helvetia and Emery complexes.
The Enlow Fork, Bailey, Mine No. 84, Robinson Run, Loveridge, Blacksville,
Buchanan, Mill Creek, VP-3, Jones Fork, VP-8, Amonate, Elk Creek, Rend Lake and
Cardinal River complexes transport coal to customers by rail.

The following table provides the location and a summary of the main
characteristics of CONSOL's mining complexes and the coal reserves associated
with these operations.

The Burning Star No. 4 mine and the Potomac mine, which in the aggregate,
produced 2.0 million tons of coal during 1997, have been closed. Two mining
complexes, Twin Branch Complex and the Holden Complex, which, in the aggregate,
produced 500,000 tons in 1997, were exchanged in November 1998 for the Vesta
coal reserves owned by the A.T. Massey Coal Company. The mines and complexes
sold or exchanged are not shown in the table.     
    
There are, in the aggregate, approximately 680 leases with respect to assigned
coal reserves. The leases have terms extending up to 30 years and generally
provide for renewal through the anticipated life of the associated mine. These
renewals are exercisable by the payment of minimum royalties.    
    
Total accessible and assigned reserves represents proved and probable coal
reserves at December 31, 1997. CONSOL assigns coal reserves to each of its
mining operations, but each mine also may have access to reserves that have not
yet been assigned to any particular mine. Unassigned reserves may be accessed by
more than one mining operation. Information with respect to proved and probable
coal reserves has been determined by CONSOL geologists and mining engineers. See
Note 22 of Notes to the Consolidated Financial Statements.    


[Map showing the location of CONSOL's mines in relation to major coal basins.]


The following provides a description of the operating characteristics of
CONSOL's principal mines by geographic region.


NORTHERN APPALACHIA MINES

Enlow Fork. The Enlow Fork mine produces coal from the Pittsburgh #8 Seam using
two longwall systems and six continuous mining machines. Coal is transported to
the surface by conveyor belts. The coal is processed in the Bailey Central

COAL RESERVES

CONSOL had an estimated 4.8 billion tons of proved and probable reserves at
December 31, 1997. Reserves are the portion of the "demonstrated" tonnage
(equivalent to "proved" and "probable") that meet CONSOL's general economic
criteria regarding mining height, preparation plant recovery, depth of
overburden and stripping ratio. Generally, these reserves would be commercially
minable at year-end price and cost levels.

CONSOL's reserves are located in northern Appalachia (52%), central Appalachia
(13%), the midwestern United States (21%) and in the western United States and
in Canada (14%).

                                       57
<PAGE>
 
    
The following table summarizes CONSOL's reserves at December 31, 1997. For
unassigned reserves, CONSOL assumes 60% recovery for reserves that can be mined
using longwall mining, 50% recovery for reserves that will be mined using other
underground methods and 90% recovery for surface mines.

Reserve estimates are based on geological data assembled and analyzed by
CONSOL's staff, which includes 14 geologists and more than 40 mining engineers,
located at individual mines, operations offices and at CONSOL's headquarters.
The reserve estimates and general economic criteria upon which they are based
are reviewed and adjusted annually to reflect production of coal from the
reserves, analysis of new engineering and geological data, changes in property
control, modification of mining methods and other factors. Reserve information,
including the quantity and quality of reserves, coal and surface ownership,
lease payments and other information relating to CONSOL's coal reserve and land
holdings, is maintained through a system of interrelated computerized databases
developed by CONSOL.

CONSOL's reserve estimates are predicated on information obtained from its
extensive, ongoing exploration drilling and in-mine channel sampling programs.
Data including elevation thickness and, where samples are available, the quality
of the coal from individual drill holes and channel samples are input into a
computerized geologic database. The information derived from the geologic
database is then combined with data on ownership or control of the mineral and
surface interests to determine the extent of the reserves in a given area.


COAL CONTRACTS
    
CONSOL sells coal to customers under arrangements that are the result of both
bidding procedures and extensive negotiations. Coal typically is sold by
contracts for terms that range from a single shipment to multi-year agreements
for millions of tons. Many contracts now allow the coal to be sourced from more
than one mine, an advantage to CONSOL because of the number of its mining
complexes, particularly in northern Appalachia. CONSOL currently sells 61% of
its coal under contracts with terms of one year or more. The pricing mechanisms
under these agreements typically consist of (1) base-price-plus-escalation
methods which allow for periodic price adjustments based on inflation indices,
or in some cases, pass-through of actual cost changes or (2) annually negotiated
prices adjusted to market. Certain contracts have features of both types of
contracts, such as limited price reopener provisions within a
base-price-plus-escalation agreement. Such reopener provisions allow both the
customer and CONSOL an opportunity to adjust price to a level close to then
current market conditions. Almost all of CONSOL's existing contracts with
reopener provisions adjust the contract price to market price at the time the
reopener provision is triggered. Market price is generally based on recent
published transactions for similar quantities and quality of coal. Reopener
provisions could result in early termination of a contract or of requirements
that certain volumes be purchased if the parties were to fail to agree on price
and other terms that may be subject to renegotiation.     

Contracts also typically contain force majeure provisions allowing suspension of
performance by CONSOL or the customer for the duration of certain events beyond
the control of the affected party, including labor disputes. Certain contracts
may terminate upon continuance of an event of force majeure for an extended
period (generally six to 12 months). Contracts also typically specify certain
minimum and maximum quality specifications regarding the coal to be delivered.
Failure to meet these conditions could result in substantial price reductions or
termination of the contract.

Although the volume to be delivered pursuant to a long-term contract is
stipulated, buyers or CONSOL have the option to vary the volume within specified
limits. In addition, a contract may provide for early termination of all or part
of the specified sales volume due to failure to agree on price or other terms
for which renegotiation is provided or for suspension of performance or
termination by the customer for force majeure events or failure of performance.

CONSOL routinely engages in efforts to renew or extend contracts scheduled to
expire. Although there are no guarantees that contracts will be renewed, CONSOL
frequently has been successful in the past in renewing or extending contracts.
The length of term, volumes specified and price typically are adjusted during
the renegotiation.


MARKETING AND SALES
    
CONSOL sells coal produced by its mining complexes and additional coal which is
purchased for resale from other producers through a sales force of 20 people.
CONSOL maintains U.S. sales offices in Atlanta, Chicago, Cleveland, Norfolk,
Philadelphia, Pittsburgh and overseas in Brussels, Belgium. In addition, CONSOL
sells coal through agents, brokers and trading companies. In 1997, CONSOL sold
75.2 million tons of coal, 84% of which was sold in domestic markets to
electricity generators, steel companies and other consumers of coal. Direct
sales by CONSOL to domestic electricity generators represented 68% of total
sales and 81% of U.S. sales in 1997. The three largest customers were Allegheny
Energy, Pennsylvania Power Company and Detroit Edison. During 1997, CONSOL
derived 23% of its total revenue from sales to its two largest customers,
Allegheny Energy and a consortium of utility companies referred to as the CAPCO
companies, which includes among others, Pennsylvania Power Company. During 1997,
contracts with Allegheny Energy accounted for more than 10% of CONSOL's
revenues.      

More than 100 technical specialists work with the direct sales force to meet the
needs of current and potential customers. Specialists review customer bid
solicitations with the sales force and then identify the coal or coal-blends
that CONSOL could provide. Specialists also may accompany the sales force on
customer calls to suggest, from a technical standpoint, how CONSOL coals could
be used to improve combustion efficiency or lower customers' costs.

If additional technical resources are required, the sales force utilizes
expertise provided by CONSOL's Research and Development Department. CONSOL's
research and development expertise in areas, including combustion, emission
control, coal coking and power plant performance, allows CONSOL to address
customer concerns on detailed technical basis. See "-- Research and
Development."


DISTRIBUTION

CONSOL employs transportation specialists who negotiate freight and equipment
agreements with various transportation suppliers, including railroads, barge
lines, terminal operators, ocean vessel brokers and trucking companies.

                                       60
<PAGE>
 
In addition, CONSOL's transportation managers coordinate with customers and with
CONSOL's mining complexes to establish shipping schedules and to order
transportation equipment necessary to meet the customer's needs. CONSOL owns or
leases more than 1,100 railroad cars for moving coal either directly to domestic
customers or to the river and sea ports for transloading to barges or vessels.

CONSOL has five towboats and a fleet of nearly 300 barges to serve customers
along the Ohio and Monongahela rivers. The barge operation allows CONSOL to
exercise control of delivery schedules and serves as temporary floating storage
of coal where land storage is unavailable. The towboat and barge fleet is sized
to accommodate the narrower channels and smaller locking facilities along the
Monongahela River on which much of CONSOL's coal is moved.

In 1997, CONSOL transported 14.8 million tons of coal by river. Third-party
shippers transported an additional 13.5 million tons of CONSOL's coal. Nearly
40% of CONSOL-produced coal moved on the inland waterways in 1997. CONSOL
estimates that shipping coal by water is as much as 80% less expensive than rail
transportation. Coal shipped on the Monongahela, Ohio and Mississippi rivers is
transported to electricity generators, steel makers and industrial customers in
the United States and overseas. Water-borne shipments of coal originate from
mines in every state in which CONSOL operates.
    
International customers and domestic coastal customers receive coal through
CONSOL's terminal at Baltimore, Maryland. The Baltimore Terminal is a 100 acre
site with a throughput capacity of 18 million tons annually and ground storage
capacity for steam and metallurgical coal. The ground storage capacity is
significant to CONSOL for several reasons. First, it provides additional
inventory storage to allow mines to continue to operate at optimal levels.
Second, the large storage capacity allows CONSOL to ensure overseas buyers that
coal will be available for rapid loading when the transporting vessel arrives at
the port, thereby minimizing demurrage charges. Finally, the storage capacity of
the terminal allows CONSOL to inventory coals of various qualities and to then
produce custom blends for overseas customers. The terminal is served by both the
Norfolk Southern and CSX Transportation railroads. The terminal berths have been
dredged to a depth of 50 feet to allow CONSOL to load larger oceangoing 
vessels.     


RESEARCH AND DEVELOPMENT

CONSOL's Research and Development Department is the largest private research
organization in the United States devoted to coal. The function of the
department is to identify, develop and apply technology to support the
production and marketing objectives of CONSOL's coal and gas operations and to
serve as a technical resource to other staff departments. The Research and
Development Department works closely with CONSOL's mines, preparation plants,
sales offices, engineering, environmental affairs and government relations
departments to address current opportunities and problems while pursuing a
longer term strategic mission to maintain CONSOL's competitive advantage in
mining and sales. The Research & Development Department employs approximately
100 engineers, scientists and staff at two locations and has an annual budget of
$11 million.

The strategic objectives of the Research and Development Department are to
understand and control the geologic factors that can limit productivity or
impair safety, to develop systems and procedures to optimize resource extraction
and utilization, to assess the value of CONSOL's products in the market place
and to address operational and environmental issues that can affect CONSOL's
customers and, as a consequence, limit the market for CONSOL's coal. CONSOL's
research and development effort is directed at both production ("upstream") and
marketing ("downstream") issues. This approach recognizes that profitability is
a function of the ability to control costs of production and the ability to
develop and access the highest value markets for CONSOL's products.

                                       61
<PAGE>
 
The goal of the upstream research is to reduce costs, to improve productivity
and to enhance the safety of CONSOL's mines and preparation plants. Among the
significant areas of research are the geophysical evaluation of reserves and
mines, the automation of mining systems, including robotic control of longwall
shearers, the improvement of underground haulage technology, the hydrological
modeling of mines and the associated geology, the control of dust and methane in
mines, and the development of computer technology for preparation plants. CONSOL
has developed sophisticated measurement and computer modeling techniques for
ground control and hydrologic modeling. These tools are used to design and
operate safe and productive mines, and to understand better the effect of mining
on the environment. CONSOL also maintains extensive testing and sampling
capabilities at its research and development facilities to address coal quality
issues, and to solve in a cost-effective manner such environmental problems as
acid mine drainage and plant emission controls. In recent years, CONSOL has
obtained (or applied for) various patents, including froth floatation control
systems to improve preparation plant efficiencies and costs, the TramVeyor(TM)
coal haulage systems to increase productivity in continuous miner sections,
devices to extend conveyor belts as mining advances without interrupting belt
operations, and a device that allows continued mine ventilation during periodic
testing.

The downstream program supports CONSOL's coal sales through the development of
improved coal use technologies, and by assigning research and development staff
to participate in the government regulatory process where it affects the use of
coal. The Research and Development Department operates a pilot combustor and a
moveable-wall coke oven to test and qualify coal for virtually any customer
application and to diagnose and solve operating problems at customer facilities
that might otherwise limit the use of CONSOL's coal. The Research and
Development Department has developed the proprietary CONSOL, Coal Quality Cost
Model ("CQCM") as a tool for determining the value of specific coals based on
the busbar power cost when they are used in electricity generating stations.
Alone, or in combination with the pilot combustor, the CQCM allows CONSOL's
sales force and its customers to identify the best coals for a given
application.

CONSOL not only has extensive coal-testing capabilities, but it can provide
customers with field diagnostic services to evaluate and solve coal combustion
problems. These capabilities not only help preserve existing business, but allow
CONSOL to generate new business opportunities. For example, CONSOL recently
resolved concerns about the use of CONSOL coal for blending in an electricity
generating station of an upper midwest electric utility. The station primarily
burned low-Btu, Western coal for blending with a lesser amount of high-sulfur
Eastern coal from another producer. The utility wanted to consider CONSOL's high
Btu, fully-washed, Pittsburgh # 8 seam coal, but was concerned that this coal
would create slagging and fouling problems, if substituted in the blend. By
testing blends in the Research & Development Department's pilot-scale coal
combustion facility and working with the utility's station operators, CONSOL
demonstrated that fully washed, high Btu coal could be part of the blend. As a
result, CONSOL's coal was qualified and ultimately chosen by the customer.

The Research and Development Department's work on the development of coal
utilization technology is directed principally at reducing the cost of
compliance with environmental regulations for existing coal-fired boilers.
CONSOL believes that existing electricity generating stations will be the site
of increased coal use as operators of these stations seek to increase the
utilization of the capacity of the generating units. The Research and
Development Department is engaged in the development and demonstration of
low-cost retrofit technology for the control of sulfur dioxide, oxides of
nitrogen and other post-combustion air emissions and for the control of solid
waste. For example, CONSOL was recently awarded a grant from the U.S. Department
of Energy to construct a pilot plant to turn scrubber sludge into pellets that
can be used as aggregate in road construction. A test of asphalt using sludge
pellets currently is being conducted at a road repair and construction project.
If successful, this technology will transform scrubber sludge, which would
otherwise have to be land-filled into a commercial product, reducing the costs
of using high-sulfur coal.

EMPLOYEES AND LABOR RELATIONS

At September 30, 1998, CONSOL had a total of 8,716 employees, of whom
approximately 4,364 were represented by the UMWA and covered by the terms of the
1998 NBCWA. The NBCWA became effective on January 1, 1998 and will expire on
December 31, 2002. This agreement is negotiated with the UMWA by the Bituminous
Coal Operators' Association on behalf of its members, which includes several
subsidiaries of CONSOL. The NBCWA also serves as a pattern agreement for other
coal producers with UMWA-represented employees. About 41% of the U.S. miners are
represented by the UMWA.

The NBCWA provided moderate wage and benefit increases and pension improvements.
The NBCWA also provided CONSOL with additional scheduling flexibility and will
reduce required contributions to multi-employer benefits funds over the life of
the contract. Since 1984, the UMWA has had only one nationwide strike, which
occurred in 1993.
CONSOL believes that the current labor environment is stable.


COMPETITION

The U.S. coal industry is highly competitive, with numerous producers in all
coal producing regions. CONSOL competes against other large producers and
hundreds of small producers in the United States and overseas. The largest
producer is estimated to have less than 15% (based on tonnage sold) of the total
U.S. market. The U.S. Department of Energy reports 1,810 active coal mines in
the United States in 1997, the latest year for which government statistics are
available. The U.S. coal industry is going through a period of rapid
consolidation. Oil, steel and utility companies have been selling their coal
assets, which have been acquired for the most part by mining companies. The most
important factors on which CONSOL competes are coal price at the mine, coal
quality, transportation costs from the mine to the customer and the reliability
of supply. Continued demand for CONSOL's coal and the prices that CONSOL obtains
are affected by demand for electricity, environmental and government regulation,
technological developments and the availability and price of competing coal and
alternative fuel supplies, including nuclear, natural gas, oil or renewable
energy, including hydroelectric power.


NON-MINING OPERATIONS

CONSOL's non-mining operations started as service, support or ancillary
functions for its mining operations. Several have grown to be stand-alone
businesses that obtain a large part of their revenues from outside customers.

FAIRMONT SUPPLY COMPANY
    
Fairmont Supply Company, headquartered in Washington, Pennsylvania, is one of
the largest general-line distributors of mining and industrial supplies in the
United States. Fairmont Supply has more than 30 customer service centers
nationwide. All Fairmont Supply sites are linked by computer to manage large
inventories of name-brand parts, supplies and equipment, which helps reduce
Fairmont Supply's distribution and product acquisition costs.    

Fairmont Supply also provides integrated supply procurement and management
services. Integrated supply procurement is a materials management strategy that
utilizes a single, full-line distributor to minimize total cost in the MRO
(maintenance, repair and operating) supply chain. Fairmont Supply offers
value-added services including on-site stores management and procurement
strategies.
    
In 1997, Fairmont Supply received ISO 9002 re-certification at its Wilmington,
Delaware, Charleston, West Virginia and Parkersburg, West Virginia customer
service centers as well as at its purchasing department in Washington,
Pennsylvania. ISO 9002 is an international certification that provides
independent verification that     

                                       63
<PAGE>
 
    
a company's operating, purchasing and other procedures meet a prescribed
standard. The certification requires annual renewal. CONSOL believes that its
ISO 9002 certification gives Fairmont Supply a marketing advantage because many
customers require that their suppliers meet this standard.     

Fairmont Supply provides mine supplies to CONSOL's mining operations.
Approximately 26% of Fairmont Supply's sales in 1997 were made to CONSOL mines.
Fairmont Supply also serves DuPont sites in the United States providing
maintenance and repair services and operating supplies and equipment in a
central location near each plant. About 32% of Fairmont Supply's revenues in
1997 were derived from sales made and services provided to DuPont, based on
contract terms and conditions. See Note 21 of Notes to Consolidated Financial
Statements.

    
Fairmont Supply operates under a Strategic Alliance Agreement with DuPont.
Fairmont Supply provides various maintenance, repair and operating supplies to
DuPont plant sites both in the United States and abroad. The products supplied
are primarily valves, fittings, bearings, electrical products, safety products
and miscellaneous industrial products. The majority of the products are shipped
to 31 large plant sites in the United States with smaller volume shipments to
approximately another 50 sites in the United States and abroad. Under the
Strategic Alliance Agreement, Fairmont provides other material management
services to 16 of the larger sites in the United States. The additional services
may include a single source integrated supply program, "in-plant" delivery
services, storeroom management, procurement services, and critical material
inspection services. The specific programs are tailored to individual plant
requirements and may vary from site to site. In 1998, DuPont was Fairmont
Supply's second largest customer in sales volume. The terms of the Strategic
Alliance Agreement are comparable to terms negotiated by Fairmont Supply with
unaffiliated parties.     

BALTIMORE TERMINAL

More than 90 million tons of coal have been shipped through CONSOL's exporting
terminal in the Port of Baltimore during the terminal's 14 years of operation.

    
Constructed in the early 1980s at a cost of about $100 million, the terminal can
either store coal or transload coal directly into vessels from rail cars. It is
also one of the few terminals in the United States served by two railroads,
Norfolk Southern and CSX Transportation. In 1997, 8 million tons of coal were
shipped through the terminal. One half of the tonnage shipped was produced by
CONSOL coal mines, the remainder by other coal producers through several coal
trading companies. In 1998, about 33% of the revenue at the terminal was
generated from coal that CONSOL shipped but that had been produced by others.
The terminal has capacity to ship 18 million tons annually.     

The terminal's berth has a depth of 50 feet, enabling the facility to handle
larger ocean-going vessels. More than 1 million tons of coal can be stored on
site, which gives the terminal the advantage of having coal available at the
site for immediate loading onto ocean-going vessels or to provide blending
capability.

NEPTUNE BULK TERMINAL

CONSOL also has a 19% interest in the Neptune Bulk Terminal located in
Vancouver, Canada. The terms of the contract governing this joint venture permit
CONSOL to transship its coal through the terminal at cost. CONSOL believes that
this arrangement gives it a competitive advantage in selling coal mined from its
Cardinal River operations.

RIVER OPERATIONS
    
CONSOL's river operations transport coal from CONSOL mines with river loadout
facilities along the Monongahela River in northern West Virginia and
southwestern Pennsylvania to customers along the Monongahela and Ohio rivers.
The river operations employ five company-owned towboats and nearly 300     

                                       64
<PAGE>
 
    
barges. Coal is towed directly to customers. In 1997, CONSOL transported 15
million tons of coal by river. Third-party shippers transported an additional
13.5 million tons of CONSOL's coal.     

KELLOGG DOCK

Kellogg Dock is located in Moduc, Randolph County on the Mississippi River in
southern Illinois. This facility transfers coal from CONSOL's Rend Lake Mine
from railcars to barges. In 1997, 1 million tons were supplied by rail to the
Kellogg dock and then transported to commercial river shippers.

ALICIA DOCK

Alicia Dock, located on the Monongahela River north of the Dilworth mine, is a
new transshipment facility with design capacity of 6 million tons of coal per
year and potential storage capacity for 0.2 million tons of coal. Coal is
transferred from rail cars to barges for customers that receive coal on the
river system. The facilities include a single-car rotary dump with a positioner,
capable of handling an average of 25 cars per hour. The rail siding provides
space for 105 cars on each side of the dumper. The Alicia Dock facility became
operational in April 1997 and throughput was 1 million tons through the end of
1997.

ASH DISPOSAL

CONSOL operates an ash disposal facility on a 61-acre site in northern West
Virginia to handle ash residues for coal customers that are unable to dispose of
ash on-site at their generating facilities. This facility became operational in
early 1994. The ash disposal facility can process 200 tons of material per hour.

CONSOL has a long-term contract with a cogeneration facility to supply coal and
take the residual fly ash and bottom ash. The fly ash is transported to the
disposal site by CONSOL-leased pressure differential rail cars. Bottom ash is
sold locally for road construction and other purposes.

GAS OPERATIONS

CONSOL has a 50% interest in the Pocahontas Gas Partnership which engages in the
production and transportation of commercial coalbed methane gases. The
Pocahontas Gas Partnership recovers pipeline-quality coalbed methane from mining
activities in southwestern Virginia and transports the gas to the interstate
pipeline system. The production from the Pocahontas Gas Partnership was
approximately 36 million cubic feet per day in 1997. CONSOL serves as operator
of the Pocahontas Gas Partnership and as operator of an adjacent coalbed methane
property. The total gas production supervised by CONSOL from these two ventures
was 53 million cubic feet per day in 1997.


LEGAL PROCEEDINGS

CONSOL is subject to numerous legal proceedings in the ordinary course of its
business. Except as described below, CONSOL does not believe that the outcome of
any such legal proceedings, if adversely determined, would have a material
adverse effect on its business, financial condition or results of operations.

    
On September 18, 1996, Union Electric, a Missouri corporation, commenced an
action in the U.S. District Court for the Eastern District of Missouri against
Consolidation Coal Company, an indirect wholly owned subsidiary of CONSOL,
CONSOL, Inc., and CONSOL Energy Inc. alleging, among other things, breach of
contract and asserting unjust enrichment claims against each defendant. The
claims relate to a long-term coal supply contract originally entered into
between Union Electric and Consolidation Coal Company on December 30, 1966.
Union Electric claims that Consolidation Coal Company breached the contract by
refusing to agree to price reductions in the per-ton price for coal when
requested to do so by Union Electric under the     

                                       65
<PAGE>
 
contract's gross inequities clause. The defendants dispute all of Union
Electric's allegations and do not believe that Union Electric has suffered any
gross inequity or is entitled to any relief under the contract. Union Electric
has estimated its damages to be $124 million plus $66 million in interest. On
August 31, 1998, CONSOL was awarded a summary judgment dismissing Union
Electric's claims against it. Union Electric has appealed the court's order
dismissing the suit.

    
CONSOL is engaged in a contract dispute with Cleveland Electric Illuminating
Company, Duquesne Light Company, Ohio Edison Company, Pennsylvania Power Company
and The Toledo Edison Company. CAPCO claims that CONSOL under the terms of the
Mansfield Plant Coal Sales Agreement dated April 10, 1987 made improper
adjustments to the coal price for certain labor, retirement and benefit costs.
CAPCO claims that they were improperly assessed $40 million as a result of the
price adjustments made by CONSOL. CONSOL has responded to CAPCO and has denied
the claims. The agreement provides for resolution of disputes by arbitration.
CONSOL has received a notice from CAPCO of its intention to submit the claims to
arbitration.

                                  REGULATION
    
The coal mining industry is subject to regulation by federal, state and local
authorities on matters such as employee health and safety, permitting and
licensing requirements, air quality standards, water pollution, plant and
wildlife protection, the reclamation and restoration of mining properties after
mining is completed, the discharge of materials into the environment, surface
subsidence from the underground mining and the effects of mining on groundwater
quality and availability. In addition, the utility industry is subject to
extensive regulation regarding the environmental impact of its power generation
activities which could affect demand for CONSOL's coal. The possibility exists
that new legislation or regulations may be adopted which may have a significant
impact on CONSOL's mining operations or its customers' ability to use coal and
may require CONSOL or its customers to change their operations significantly or
incur substantial costs.     

Numerous governmental permits or approvals are required for mining operations.
CONSOL believes all permits currently required to conduct its present mining
operations have been obtained. CONSOL may be required to prepare and present to
federal, state or local authorities data pertaining to the effect or impact that
any proposed exploration for or production of coal may have upon the
environment. All requirements imposed by any such authority may be costly and
time-consuming and may delay commencement or continuation of exploration or
production operations. Future legislation and administrative regulations may
emphasize the protection of the environment and, as a consequence, the
activities of CONSOL may be more closely regulated. Such legislation and
regulations, as well as future interpretations of existing laws, may require
substantial increases in equipment and operating costs to CONSOL and delays,
interruptions or a termination of operations, the extent of which cannot be
predicted.

    
CONSOL endeavors to conduct mining operations in compliance with all applicable
federal, state and local laws and regulations. However, because of extensive and
comprehensive regulatory requirements, violations during mining operations are
not unusual in the industry and, notwithstanding compliance efforts, CONSOL does
not believe such violations can be eliminated completely. None of the violations
to date or the monetary penalties assessed have been material.     

While it is not possible to quantify the costs of compliance with all applicable
federal and state laws, those costs have been and are expected to continue to be
significant. It is estimated that CONSOL will make capital expenditures for
environmental control facilities in the amount of approximately $4 million in
1998, as compared to $4 million and $5 million in 1996 and 1997, respectively.
These costs are in addition to reclamation costs. Compliance with these laws has
substantially increased the cost of coal mining, but is, in general, a cost
common to all domestic coal producers.


MINE HEALTH AND SAFETY LAWS
    
Stringent safety and health standards have been imposed by federal legislation
since 1969 when the Federal Coal Mine Health and Safety Act of 1969 was adopted.
The Mine Health and Safety Act of 1969 resulted in increased operating costs and
reduced productivity. The Federal Mine Safety and Health Act of 1977, which
significantly expanded the enforcement of health and safety standards of the
Mine Health and Safety Act of 1969, imposes comprehensive safety and health
standards on all mining operations. Regulations are comprehensive and affect
numerous aspects of mining operations, including training of mine personnel,
mining procedures, blasting, the equipment used in mining operations and other
matters. The Mine Safety and Health Administration monitors compliance with
these federal laws and regulations. In addition, as part of the Mine Health and
Safety Act of 1969 and the Mine Safety and Health Act of 1977, the Black Lung
Acts require payments of benefits by all businesses conducting current mining
operations to coal miners with pneumoconiosis (black lung) and to certain
survivors of a miner who dies from pneumoconiosis.     

                                       67
<PAGE>
 
Most of the states in which CONSOL operates have state programs for mine safety
and health regulation and enforcement. In combination, federal and state safety
and health regulation in the coal mining industry is perhaps the most
comprehensive and pervasive system for protection of employee safety and health
affecting any segment of the industry. Even the most minute aspects of mine
operations, particularly underground mine operations, are subject to extensive
regulation. This regulation has a significant effect on CONSOL's operating
costs. However, CONSOL's competitors in all of the areas in which it operates
are subject to the same degree of regulation.

One of CONSOL's goals is to achieve excellent health and safety performance as
measured by accident frequency rates and other measures. CONSOL believes that
attainment of this goal is inherently tied to the attainment of productivity and
financial goals. CONSOL seeks to implement this goal by training employees in
safe work practices; openly communicating with employees; establishing,
following, and improving safety standards; involving employees in establishing
safety standards; and recording, reporting and investigating all accidents,
incidents and losses to avoid reoccurrences.


BLACK LUNG LEGISLATION
    
In order to compensate (1) miners who are totally disabled due to pneumoconiosis
and (2) certain survivors of miners who died from the disease and who were last
employed as miners prior to 1970 or where no responsible coal mine operator has
been identified for claims where the miner's last coal employment was after
December 31, 1969, the Black Lung Acts levied a tax on production of $1.10 per
ton for deep-mined coal and $.55 per ton for surface-mined coal, but not to
exceed 4.4% of the sales price. In addition, the Black Lung Acts provide that
certain claims for which coal operators had previously been responsible will be
obligations of the government trust funded by the tax. The Revenue Act of 1987
extended the termination date of the tax from January 1, 1996 to the earlier of
January 1, 2014, or the date on which the government trust becomes solvent. For
miners last employed as miners after 1969 who are determined to have contracted
black lung, CONSOL self insures against potential cost using actuarial
determined estimates of the cost of present and future claims. CONSOL's
subsidiaries are also liable under state statutes for pneumoconiosis (black
lung) claims.     

    
In the past, legislation on black lung reform has been introduced, but not
enacted, in Congress. It is possible that such legislation will be reintroduced.
Such legislation could restrict the evidence that can be offered by a mining
company, establish a standard for evaluation of evidence that greatly favors
black lung claimants, allow claimants who have been denied benefits at any time
since 1981 to refile their claims for consideration under the new law, make
surviving spouse benefits significantly easier to obtain and retroactively waive
repayment of preliminarily awarded benefits that are later determined to have
been improperly paid. If this or similar legislation is passed, the number of
claimants who are awarded benefits could significantly increase. There can be no
assurance that such proposed legislation or other proposed changes in black lung
legislation will not have an adverse effect on CONSOL.     

The U.S. Department of Labor has issued proposed amendments to the regulations
implementing the federal black lung laws which, among other things, establish a
presumption in favor of a claimant's treating physician and limit a coal
operator's ability to introduce medical evidence regarding the claimant's
medical condition. If adopted, the amendments could have an adverse impact on
CONSOL, the extent of which cannot be accurately predicted.

                                       68

WORKERS' COMPENSATION

CONSOL is required to compensate employees for work-related injuries. Several
states in which CONSOL operates consider changes in workers compensation laws
from time to time. Such changes, if enacted, could adversely affect CONSOL's
financial condition and results of operation.

RETIREE HEALTH BENEFITS LEGISLATION

The Coal Industry Retiree Health Benefits Act of 1992 requires CONSOL to make
payments to fund the cost of health benefits for CONSOL's and other coal
industry retirees. As a result of a recent U.S. Supreme Court decision, CONSOL
may be required to increase its share of such payments.

ENVIRONMENTAL LAWS
    
CONSOL is subject to various Federal environmental laws, including the federal
Surface Mining Control and Reclamation Act of 1977, the Clean Air Act, the Clean
Water Act, the federal Comprehensive Environmental Response, Compensation and
Liability Act, and the federal Resource Conservation Recovery Act as well as
state laws of similar scope in each state in which CONSOL operates. These
environmental laws require permitting and/or approval of many aspects of coal
mining operations, and to that end both federal and state inspectors regularly
visit CONSOL's mines and other facilities to assure compliance. CONSOL has
ongoing compliance and permitting programs to assure compliance with such
Environmental Laws.     

Given the retroactive nature of certain environmental laws, CONSOL has incurred
and may in the future incur liabilities in connection with properties and
facilities currently or previously owned or operated as well as sites to which
it sent waste materials.

SURFACE MINING CONTROL AND RECLAMATION ACT
    
The Surface Mining Control and Reclamation Act establishes operational,
reclamation and closure standards for all aspects of surface mining as well as
many aspects of deep mining. The act requires that comprehensive environmental
protection and reclamation standards be met during the course of and upon
completion of mining activities. Permits for surface mining operations must be
obtained from the federal Office of Surface Mining Reclamation and Enforcement
or, where state regulatory agencies have adopted federally approved state
programs under the act, the appropriate state regulatory authority. All states
in which CONSOL's active mining operations are located have achieved primary
jurisdiction for enforcement of the act through approved state programs.     

    
The Surface Mining Control and Reclamation Act and similar state statutes, among
other things, require that mined property be restored in accordance with
specified standards and approved reclamation plans. The act requires CONSOL to
restore the surface to approximate the original contours as contemporaneously as
practicable with the completion of surface mining operations. The mine operator
must submit a bond or otherwise secure the performance of these reclamation
obligations. The earliest a reclamation bond can be released is five years after
reclamation has been achieved. Some states, including Pennsylvania, impose on
mine operators the responsibility for repairing or compensating for damage
occurring on the surface as a result of mine subsidence, a consequence of
longwall mining. In addition, the Abandoned Mine Lands Act, which is part of the
Surface Mining Control and Reclamation Act, imposes a tax on all current mining
operations, the proceeds of which are used to restore mines closed before 1977.
The maximum tax is $.35 per ton on surface-mined coal and $.15 per ton on
underground-mined coal.     

CONSOL accrues for the costs of final mine closure, including the cost of
treating mine water discharge where necessary, over the estimated useful mining
life of the property and for current mine disturbance which will be reclaimed
prior to final mine closure. The establishment of liability for the current
disturbance and final mine 

                                       69
<PAGE>
 
closure reclamation is based upon permit requirements and requires various
estimates and assumptions, principally associated with costs and production
levels. The reclamation costs, mine-closing costs and other environmental
liability accruals were $321 million at September 30, 1998. The amount that was
included as an operating expense for the nine-month period ended September 30,
1998 was $7 million, while the related cash expense for such liability in such
period was $22 million. Although CONSOL's management believes it is making
adequate provisions for all expected reclamation and other costs associated with
mine closures, future operating results would be adversely affected if such
accruals were later determined to be insufficient.

    
Under the Surface Mining Control and Reclamation Act, responsibility for
unabated violations, unpaid civil penalties and unpaid reclamation fees of
independent contract mine operators can be imputed to other companies which are
deemed, according to the regulations, to have "owned" or "controlled" the
contract mine operator. Sanctions against the "owner" or "controller" are quite
severe and can include being blocked from receiving new permits and revocation
of any permits that have been issued since the time of the violations or, in the
case of civil penalties and reclamation fees, since the time such amounts became
due. CONSOL is not aware of any currently pending or asserted claims relating to
the "ownership" or "control" theories discussed above. However, there can be no
assurance that such claims may or may not develop in the future.     


CLEAN AIR ACT
    
The federal Clean Air Act and similar state laws, which regulate emissions into
the air, affect coal mining and processing operations primarily through
permitting and/or emissions control requirements. In addition, the U.S.
Environmental Protection Agency has issued certain and is considering further
regulations relating to fugitive dust and coal combustion emissions which could
restrict CONSOL's ability to develop new mines or require CONSOL to modify its
operations. In July 1997, the Environmental Protection Agency adopted new, more
stringent National Ambient Air Quality Standards for particulate matter which
may require some states to change existing implementation plans. These National
Ambient Air Quality Standards are expected to be implemented by 2003. Because
coal mining operations emit particulate matter, CONSOL's mining operations and
utility customers are likely to be directly affected when the revisions to the
National Ambient Air Quality Standards are implemented by the states.
Regulations may restrict CONSOL's ability to develop new mines or could require
CONSOL to modify its existing operations, and may have a material adverse effect
on CONSOL's financial condition and results of operations.     

The Clean Air Act also indirectly affects coal mining operations by extensively
regulating the air emissions of coal-fueled electric power generating plants.
The Clean Air Act requires reduction of sulfur dioxide emissions from electric
power generation plants in two phases. Only certain facilities are subject to
the Phase I requirements. By the year 2000, Phase II requires nearly all
facilities to reduce such emissions. The affected utilities will be able to meet
these requirements by switching to lower sulfur fuels, by installing pollution
control devices such as scrubbers, by reducing electricity generating levels or
by purchasing or trading so-called pollution "credits." Specific emissions
sources receive these "credits" which utilities and industrial concerns can
trade or sell to allow other units to emit higher levels of sulfur dioxide. In
addition, the Clean Air Act requires a study of utility power plant emission of
certain toxic substances and their eventual regulation, if warranted. The effect
of the Clean Air Act cannot be completely ascertained at this time, although the
sulfur dioxide emissions reduction requirement is projected generally to
increase the demand for low-sulfur coal and potentially decrease demand for high
sulfur coal.

    
The Clean Air Act also indirectly affects coal mining operations by requiring
utilities that currently are major sources of nitrogen oxides in moderate or
higher ozone nonattainment areas to install reasonably available control
technology for nitrogen oxides, which are precursors of ozone. The Environmental
Protection Agency recently announced a proposal that would require 22 eastern
states to make substantial reductions in nitrogen oxide     

                                       70
<PAGE>
 
    
emissions by the year 2003. The Environmental Protection Agency expects such
states will achieve these reductions by requiring power plants to make
substantial reductions in their nitrogen oxide emissions. This in turn will
require power plants to install reasonably available control technology and
additional control measures. Installation of reasonably available control
technology and additional measures required under the Environmental Protection
Agency proposal will make it more costly to operate coal-fired plants and,
depending on the requirements of individual state implementation plans and the
development of revised new source performance standards, could make coal a less
attractive fuel alternative in the planning and building of utility power plants
in the future. Any reduction in coal's share of the capacity for power
generation could have a material adverse effect on CONSOL's business, financial
condition and results of operations. The effect such regulations, or other
requirements that may be imposed in the future, could have on the coal industry
in general and on CONSOL in particular cannot be predicted with certainty. No
assurance can be given that the implementation of the Clean Air Act, the new
National Ambient Air Quality Standards or any other future regulatory provisions
will not materially adversely affect CONSOL's business, financial condition or
results of operations.     

    
Impact of the Framework Convention On Global Climate Change. The United States
and more than 160 other nations are signatories to the 1992 Framework Convention
on Global Climate Change which is intended to limit or capture emissions of
greenhouse gases, such as carbon dioxide. In the Kyoto Protocol, the signatories
to the Framework Convention on Global Climate Change established a binding set
of emissions targets for developed nations. The specific limits vary from
country to country. Under the terms of Kyoto Protocol, the United States would
be required to reduce emissions to 93% of 1990 levels over a five-year budget
period from 2008 through 2012. The Clinton Administration signed the protocol in
November 1998. Although the U.S. Senate has not yet ratified the Kyoto Protocol
and no comprehensive regulations focusing on greenhouse gas emissions have been
enacted, efforts to control greenhouse gas emissions could result in reduced use
of coal if electric power generators switch to lower carbon sources of fuel.
Such restrictions, if established through regulation or legislation, could have
a material adverse effect on CONSOL's business, financial condition and results
of operations.     

CLEAN WATER ACT
    
The federal Clean Water Act affects coal mining operations by imposing
restrictions on effluent discharge into waters. Regular monitoring, as well as
compliance with reporting requirements and performance standards, are
preconditions for the issuance and renewal of permits governing the discharge of
pollutants into water. CONSOL believes it has obtained all permits required
under the Clean Water Act and that compliance with the Clean Water Act will not
materially adversely affect its business, financial condition and results of
operations. CONSOL has received several notices of violations from the Ohio
Environmental Protection Agency at its Powhatan Mine No. 4, located near
Clarington, Monroe County, Ohio. In September 1998, CONSOL entered into a
settlement agreement with the Ohio Environmental Protection Agency and finalized
a consent decree with the Ohio Environmental Protection Agency reflecting the
resolution of outstanding issues. This settlement included a payment of $102,620
and a schedule to achieve compliance with its permit. CONSOL is meeting all Ohio
Environmental Protection Agency requirements on the schedule set forth in the
consent decree.     

COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION AND LIABILITY ACT
    
The Comprehensive Environmental Response, Compensation and Liability Act and
similar state laws affect coal mining operations by, among other things,
imposing cleanup requirements for threatened or actual releases of hazardous
substances that may endanger public health or welfare or the environment. Under
the Comprehensive Environmental Response, Compensation and Liability Act, joint
and several liability may be imposed on waste generators, site owners and
operators and others regardless of fault or the legality of the original
disposal activity. Although waste substances generated by coal mining and
processing are generally not regarded as hazardous substances for the purposes
of the Comprehensive Environmental Response, Compensation and Liability Act,
some products used by coal companies in operations, such as chemicals, and     

                                       71
<PAGE>
 
    
the disposal of such products, are governed by the statute. Thus, coal mines
currently or previously owned or operated by CONSOL, and sites to which CONSOL
sent waste materials, may be subject to liability under the Comprehensive
Environmental Response, Compensation and Liability Act and similar state laws.
CONSOL has been, from time to time, the subject of administrative proceedings,
litigation and investigations relating to environmental matters and has also
been named as a potentially responsible party at several Superfund sites. CONSOL
believes, based on various factors, that the liabilities associated with the
Superfund sites should not have a material adverse effect on its financial
condition or results of operations. However, there can be no assurances that
CONSOL will not become involved in future proceedings, litigation or
investigations or that such liabilities will not be material.     

RESOURCE CONSERVATION RECOVERY ACT

    
The federal Resource Conservation Recovery Act affects coal mining operations by
imposing requirements for the treatment, storage and disposal of hazardous
wastes. Although many mining wastes are excluded from the regulatory definition
of hazardous waste, and coal mining operations covered by the Surface Mining
Control and Reclamation Act permits are exempted from regulation under the
Resource Conservation Recovery Act by statute, the Environmental Protection
Agency may consider the possibility of expanding regulation of mining wastes
under the Resource Conservation Recovery Act. Such expansion could have a
material adverse affect on CONSOL's results of operations and financial
condition.     

FEDERAL COAL LEASING AMENDMENTS ACT
    
Although CONSOL currently does not have mining operations on federal coal
leases, mining operations on federal lands in the West are affected by
regulations of the U.S. Department of the Interior. The Federal Coal Leasing
Amendments Act of 1976 amended the Mineral Lands Leasing Act of 1920 which
authorized the leasing of federal lands for coal mining. The Federal Coal
Leasing Amendments Act increased the royalties payable to the U.S. Government
for federal coal leases and required diligent development and continuous
operations of leased reserves within a specified period of time. Regulations
adopted by the U.S. Department of the Interior to implement such legislation
could affect coal mining by CONSOL from federal leases if operations were
developed on such leases.

Long-Term Incentive Plan     
    
Certain officers of CONSOL and its subsidiaries participate in a long-term
incentive plan which is administered by the Vice President-Human Resources of
CONSOL Inc. at the direction of the Chairman of the Board of Directors of
CONSOL. The Board of Directors may adjust award targets to reflect certain
extraordinary events, including strategic restructuring and new investments for
capital expansion. The Board of Directors has the discretion to terminate,
suspend, withdraw or modify the Long-Term Incentive Plan in whole or in 
part.     
    
Awards under the Long-Term Incentive Plan are based on CONSOL's results of
operations. Performance targets are tied to after tax operating income and
operating cash flow. Awards under the Long-Term Incentive Plan are granted in
units, each of which has a nominal value of $100. The awards have a three-year
term and are payable in the third year. The target for the first year is the
profit objective of CONSOL for that year. Years two and three are based upon
targets stated in CONSOL's long-term business plan in place prior to the
beginning of the award cycle. Awards may vary from 0% to 150% of the nominal
value of the unit depending upon the targeted results of operations for CONSOL.
For example, if the results of operations average 100% of the target for the
relevant period, each unit would have a value of $100.00. If the results of
operations average less than 100% of the target for the relevant period, each
unit would have a value of $0.00. If the results of operations average 150% or
more of the target for the relevant period, each unit would have a value of
$150.00. A recipient may elect to receive payment when an award is earned or he
may defer the payment of such award. Deferred awards accrue compounded interest
at an annual rate equal to Moody's AAA 10-year municipal bond rate.

1999 Equity Incentive Plan     

General
    
CONSOL has adopted the 1999 Equity Incentive Plan (the "Plan"). A maximum of
shares of common stock has been reserved for issuance under the Plan, generally
subject to equitable adjustment upon the occurrence of any stock dividend, stock
split, subdivision or consolidation.     

Pursuant to the Plan, CONSOL may grant Stock Options (including "incentive stock
options" and "nonqualified stock options"), stock appreciation rights ("SARs")
(either in connection with stock options granted under the Plan or independently
of options), performance awards and other stock- or cash-based awards
("Awards"). It is the intent of CONSOL that certain Awards under the Plan will
satisfy applicable requirements of section 162(m) ("Section 162(m)") of the
Code.

The Plan will be administered by the Compensation Committee. The Compensation
Committee has full authority, subject to the provisions of the Plan and except
with respect to nonemployee directors, to, among other things, determine the
persons to whom Awards will be granted, determine the terms and conditions
(including any applicable performance criteria) of such Awards, and prescribe,
amend and rescind rules and regulations relating to the Plan.

Grants of Awards may be made under the Plan to selected employees of CONSOL and
its present or future subsidiaries, in the discretion of the Compensation
Committee.

Stock Options and Appreciation Rights
    
Stock options may be either "incentive stock options," as such term is defined
in Section 422 of the Code, or nonqualified stock options. The exercise price
per share of Class A common stock subject to an option may not be less than the
fair market value of a share of common stock on the date of grant.     

Stock Options and SARs will be exercisable at such times and upon such
conditions as the Compensation Committee may determine, as reflected in the
applicable Award agreement. The exercise period shall be determined by the
Compensation Committee except that, in the case of an incentive stock option,
such exercise period may not exceed ten years from the date of grant of such
incentive stock option.

The Compensation Committee will set forth in the applicable Award agreement the
treatment of stock options and SARs in the event that the employment of a
participant is terminated.

Stock Awards
    
A Stock Award is an Award of the right to receive cash or common stock at a
future date that may be subject to such restrictions on transferability and
other restrictions as the Compensation Committee may impose at the date of grant
or thereafter, which restrictions may lapse separately or in combination at such
times, under such circumstances (including without limitation a specified period
of employment or the satisfaction of preestablished performance goals), in such
installments, or otherwise, as the Compensation Committee may determine. All
other terms and conditions of Stock Awards will be set forth in the applicable
Award agreement.     

Performance Awards

The Performance Award component of the Plan provides for the payment of Awards
to participants if, and only to the extent that, performance goals established
by the Compensation Committee are met with respect to the appropriate applicable
performance period. The Compensation Committee will establish performance goals
expressed in terms of the achievement of one or more performance measures.

Certain Limitations
    
No participant in the Plan may be granted, in respect of any calendar year,
Stock Options or SARs representing an aggregate of more than shares of common
stock, Stock Awards covering or relating to more than shares of common stock or
Performance Awards having an aggregate value determined on the date of grant in
excess of $ .     

Change in Control

Unless otherwise provided in an Award agreement, in the event of a "Change in
Control" of CONSOL (as defined in the Plan), each unvested equity Award
outstanding under the Plan will be vested.

Amendment and Termination

The Plan may, at any time and from time to time, be altered, amended, suspended,
or terminated by the Board of Directors, in whole or in part, except that (i) no
amendment or alteration that would adversely affect the rights of any
participant under any Award previously granted to such participant shall be made
without the consent of such participant and (ii) no amendment or alteration
shall be effective prior to its approval by the stockholders of CONSOL to the
extent such approval is required by applicable law.

                                       80
<PAGE>
 
Transferability

Except as otherwise determined by the Compensation Committee, awards granted
under the Plan may not be transferred other than by will or by the laws of
descent and distribution.


EMPLOYMENT AGREEMENTS
    
Employment Agreement With Mr. Harvey. J. Brett Harvey entered into an employment
agreement with CONSOL and CONSOL Inc. on December 11, 1997. Under the terms of
this contract, Mr. Harvey assumed his current positions as the President and
Chief Executive Officer of both companies on January 1, 1998. The employment
agreement terminates on December 31, 2002 unless it is terminated earlier. Mr.
Harvey's employment will terminate if (1) he becomes disabled and would be
eligible to receive disability benefits under CONSOL Inc.'s employee retirement
plan, (2) if either party terminates the agreement or (3) for cause as
determined by the Board of Directors of CONSOL at any time. If the agreement is
terminated other than by CONSOL for cause or if Mr. Harvey resigns, Mr. Harvey
will receive severance payments in an amount equal to any incentive compensation
received in the preceding 12 months and his then current base salary. These
amounts would be paid to Mr. Harvey until the end of the term of the employment
agreement. In the event of termination for cause, Mr. Harvey's compensation and
benefits terminate at the end of the month in which the notice of termination is
given.     
    
As compensation for his services during the term of the employment agreement,
Mr. Harvey receives a yearly base salary of $390,000. He is entitled to
participate in all incentive compensation programs for senior management of
CONSOL Inc., including short-term and long-term incentive pay programs. He also
is eligible for all employee benefit plans and policies applicable to CONSOL
Inc. employees. For employee retirement plans purposes, Mr. Harvey will receive
11 years of additional service credit representing his years of employment at
PacifiCorp, deducting from any such benefits amounts payable to him pursuant to
any retirement or similar plans of PacifiCorp.     
    
Mr. Harvey's employment agreement contains certain confidentiality and non-
competition obligations. Mr. Harvey must keep CONSOL's non-public information
confidential during the term of the employment agreement and for a period of 12
months after his termination. Mr. Harvey has agreed not to compete with the
business of CONSOL for so long as he receives severance benefits under the terms
of the employment agreement.     

Consulting Arrangement With Mr. Brown. Mr. Brown entered into a consulting
agreement with CONSOL Inc. on December 9, 1996 which terminated on June 30,
1998. CONSOL Inc. and Mr. Brown have agreed to continue this consulting
arrangement on a month-to-month basis. Mr. Brown will receive a base consulting
fee of $540,000 per year which will be paid in equal monthly installments. The
base fee may be increased by the Board of Directors of CONSOL Inc.

             CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
    
PURCHASE OF SHARES FROM DUPONT ENERGY     
    
Indemnification Under Purchase Agreement. In November 1998, CONSOL purchased
51,139,156 shares of common stock from DuPont Energy for a purchase price of
$500 million. The purchase of shares from DuPont Energy was completed pursuant
to an agreement entered into in September 1998 among DuPont, DuPont Energy,
Rheinbraun and CONSOL. Subject to certain limitations, DuPont agreed to
indemnify Rheinbraun and CONSOL in respect of any losses incurred by Rheinbraun
as a result of the purchase of shares from DuPont Energy, and 47% of any and all
losses incurred by CONSOL and its subsidiaries arising or related to the period
prior to the closing date of the purchase of shares from DuPont Energy with
respect to the following:     
    
   .  environmental matters (including the failure to obtain any permits or to
      comply with laws governing the generation, handling, storage,
      transportation, disposal or remediation of hazardous material only to the
      extent these losses exceed $50 million),     
    
   .  litigation, only to the extent losses then exceed $40 million     
    
   .  taxes, and     
    
   .  properties of Conoco or its mineral divisions.     
    
Except for indemnification as to the mineral divisions of Conoco, DuPont is only
obligated to indemnify CONSOL and Rheinbraun at such time that all losses exceed
$20 million (calculated on a pre-tax basis). At that time, DuPont's
indemnification will include the first $20 million of such losses. DuPont is
obligated to indemnify CONSOL and Rheinbraun for liabilities arising out of the
mineral division of Conoco on a dollar-for-dollar basis. In no event will
DuPont's indemnification obligations in the aggregate exceed $500 million.     
    
Registration Rights. In connection with the purchase of shares from DuPont
Energy, DuPont and DuPont Energy agreed not to dispose of any of the remaining
shares of common stock held by DuPont Energy (including securities issued in
exchange for, in lieu of or as a dividend on such shares of common stock) during
the 180 days after the closing date of the purchase of shares from DuPont
Energy. After the 180 days, DuPont Energy will have the right to dispose of the
shares     
    
   .  pursuant to registration rights previously granted to DuPont Energy under
the Shareholders Agreement, or     
    
   .  in a private sale or sales conforming to the Securities Act.     
    
DuPont Energy may not, and DuPont will cause DuPont Energy not to, effect any
public sale of shares during the seven days prior to and the 90 days after any
underwritten registered financing by CONSOL has become effective or such longer
period (not to exceed 180 days) as the underwriter may require consistent with
customary practice.     
    
The agreement provides that DuPont will have two demand registration rights at
DuPont's expense prior to December 31, 2001.     
    
PAYMENT OF DIVIDENDS     
    
Prior to the closing of the purchase of shares from DuPont Energy, CONSOL paid a
dividend of $60 million, an amount which approximates CONSOL's regular annual
dividend based on 1998 results for the period elapsed      

                                       82
<PAGE>
 
    
prior to the payment of the purchase price of the shares. In December 1998,
CONSOL paid an additional dividend of $20 million.     
    
REGISTRATION RIGHTS     
    
CONSOL and Rheinbraun A.G. and Rheinbraun US GmbH have entered into a
Registration Rights Agreement that provides that, upon the request of Rheinbraun
A.G. or Rheinbraun US GmbH, CONSOL will use its best efforts to effect the
registration under the applicable federal and state securities laws of any of
the shares of common stock (or any other securities issued with respect to such
common stock). Rheinbraun will also have the right, subject to certain
limitations, to include these securities in certain other registrations of
securities initiated by CONSOL on its own behalf or on behalf of its other
stockholders. CONSOL generally will be required to pay all out-of-pocket costs
and expenses in connection with each such registration. Such registration rights
will be assignable by Rheinbraun. The agreement contains customary terms and
provisions with respect to, among other things, registration procedures and
certain rights to indemnification and contribution granted by the parties
thereunder in connection with such a registration.

                        SHARES ELIGIBLE FOR FUTURE SALE

    
After the offering, CONSOL will have 80,267,559 shares of common stock
outstanding. If the underwriters exercise their over-allotment option in full,
CONSOL will have a total of 83,657,559 shares outstanding. All of the common
stock sold in the offering will be freely transferable without restriction or
further registration under the Securities Act of 1933, except for shares
acquired by certain of CONSOL's directors and senior officers. Rheinbraun,
DuPont and certain of CONSOL's directors and senior officers have agreed not to
sell or dispose of any common stock for a period of 180 days after the date of
this prospectus, without J.P. Morgan Securities Inc.'s prior written consent.
CONSOL can give no assurance concerning how long these parties will continue to
hold their common stock after the offering. See "Risk Factors--Shares Eligible
for Future Sale" and "Underwriting."     
    
Any common stock held by one of CONSOL's affiliates will be subject to the
resale limitations required by Rule 144 under the Securities Act of 1933. Rule
144 defines an affiliate as a person that directly or indirectly, through one or
more intermediaries, controls or is controlled by, or is under common control
with, the issuer. After the offering, Rheinbraun will be an affiliate of CONSOL.
Therefore, as long as Rheinbraun remains an affiliate, Rheinbraun may sell its
common stock only:     
    
   .  pursuant to an effective registration statement under the Securities Act
      of 1933;     
    
   .  in accordance with Rule 144; or     
    
   .  pursuant to another exemption from registration.     
    
Rheinbraun is not under any contractual obligation to retain its common stock,
except during the 180-day period noted above.     
    
In general, a stockholder subject to Rule 144 who has owned common stock of an
issuer for at least one year may, within any three-month period, sell up to the
greater of (1) 1% of the total number of shares of common stock then outstanding
and (2) the average weekly trading volume of the common stock during the four
weeks preceding the stockholder's required notice of sale. Rule 144 requires
stockholders to aggregate their sales with other affiliated stockholders for
purposes of complying with this volume limitation. A stockholder who has owned
common stock for at least two years, and who has not been an affiliate of the
issuer for at least 90 days, may sell common stock free from the volume
limitation and notice requirements of Rule 144.     
    
DuPont and Rheinbraun each is entitled to require CONSOL to register its shares
for sale under the Securities Act of 1933 after the expiration of the 180-day
period noted above. See "Risk Factors?Shares Eligible for Future Sale."     
    
CONSOL cannot estimate the number of shares of common stock that may be sold
pursuant to the above sale methods because such sales will depend on market
prices, the circumstances of sellers and other factors.     
    
Prior to this offering, there has been no market for the common stock. CONSOL
can make no prediction about the effect, if any, that future sales of common
stock or the availability of such shares for sale would have on the prevailing
market price of the common stock. Nevertheless, future sales by CONSOL,
Rheinbraun or DuPont of substantial amounts of common stock, or the perception
that such sales may occur, could adversely affect the prevailing market price of
the common stock. In addition, sales and the perception of likely sales     

                                      86
<PAGE>
 
    
could impair CONSOL's ability to raise additional capital through the sale of
additional common stock or other equity securities. See "Certain Relationships
and Related Party Transactions--Registration Rights"

                         DESCRIPTION OF CAPITAL STOCK

    
CONSOL's authorized capital stock consists of 500,000,000 shares of common
stock, $.01 par value per share.  After giving effect to the offering, the
issued and outstanding capital stock of CONSOL will consist of 80,267,558 shares
of common stock (or 83,657,558 if the Underwriters' over-allotment option is
exercised in full).     

COMMON STOCK
    
As of February 1, 1999, there were 57,667,559 shares of common stock
outstanding, which were held of record by three stockholders.  The holders of
common stock are entitled to one vote per share on all matters submitted to a
vote of the stockholders.  Cumulative voting of shares of common stock is
prohibited, which means that the holders of a majority of shares voting for the
election of directors can elect all members of the Board of Directors.  Except
as otherwise required by applicable law, a majority vote is sufficient for any
act of stockholders.  The holders of common stock are entitled to receive
ratably such dividends, if any, as may be declared from time to time by the
Board of Directors out of funds legally available therefor.  In the event of
liquidation, dissolution, or winding up of CONSOL, the holders of common stock
are entitled to share ratably in all assets remaining after payment of
liabilities.  The holders of common stock have no preemptive or conversion
rights or other subscription rights, and there are no redemption or sinking fund
provisions applicable to the common stock.  All of the outstanding shares of
common stock are fully paid and nonassessable, and all of the shares of common
stock offered hereby, when issued, will be fully paid and nonassessable.  DuPont
has the right to require CONSOL to effect the registration of its shares under
the Securities Act in certain circumstances.     
    
DELAWARE STATUTE     
    
CONSOL is a Delaware corporation subject to Section 203 of the Delaware General
Corporation Law.  Section 203 provides that a corporation generally may not
engage in any business combination with any interested stockholder for a period
of three years following the time that such stockholder became an interested
stockholder.  Section 203 applies unless:     
    
     .    prior to the time a stockholder becomes an interested stockholder, the
          board of directors of the corporation approved either the business
          combination or the transaction which resulted in the stockholder
          becoming an interested stockholder;    
    
     .    upon consummation of the transaction which resulted in the stockholder
          becoming an interested stockholder, the interested stockholder owned
          at least 85% of the voting stock of the corporation outstanding at the
          time the transaction commenced (excluding certain shares); or    
    
     .    on or after such date the stockholder became an interested
          stockholder, the business combination is approved by the board of
          directors of the corporation and authorized at an annual or special
          meeting of stockholders, and not by written consent, by the
          affirmative vote of at least 66 2/3% of the outstanding voting stock
          which is not owned by the interested stockholder.    
    
An "interested stockholder" is defined to include:     
    
     .    any person that is the owner of 15% or more of the outstanding voting
          stock of the corporation or is an affiliate or associate of the
          corporation and was the owner of 15% or more of the outstanding voting
          stock of the corporation at any time within the three-year period
          immediately prior to the relevant date; and    

                                      88
<PAGE>
 
    
     .    the affiliates and associates of any such person.     
    
Section 203 defines a business combination to include:     
    
     .    any merger or consolidation involving the corporation and the
          interested stockholder;    
    
     .    any sale, transfer, pledge or other disposition of 10% or more of the
          assets of the corporation involving the interested stockholder;     
    
     .    certain transactions that result in the issuance or transfer by the
          corporation of any stock of the corporation to the interested
          stockholder;    
    
     .    any transaction involving the corporation that increases the
          proportionate share of the stock of any class or series of the
          corporation beneficially owned by the interested stockholder; or    
    
     .    the receipt by the interested stockholder of any loans, advances,
          guarantees, pledges or other financial benefits provided through the
          corporation. In general, Section 203 defines an interested stockholder
          as any entity or person beneficially owning 15% or more of the
          outstanding voting stock of the corporation and any entity or person
          affiliated with or controlling or controlled by such entity or
          person.    
    
Under certain circumstances, Section 203 makes it more difficult for an
interested stockholder to effect various business combinations with a
corporation during the three-year period, although the stockholders may elect to
exclude a corporation from the restrictions imposed under Section 203.

                               TAX CONSIDERATIONS     

    
The following is a general discussion of certain United States federal tax
considerations applicable to the ownership and disposition of common stock by
"Non-U.S. Holders."  In general, a "Non-U.S. Holder" is a beneficial owner of
common stock other than:     
    
     .    a citizen or resident of the United States,     
    
     .    a corporation or partnership created or organized in the United States
          or under the laws of the United States or of any state,    
    
     .    an estate or partnership, the income of which is includible in gross
          income for United States federal income tax purposes regardless of its
          source, or     
    
     .    a trust the administration of which is subject to the primary
          supervision of a court within the United States and for which one or
          more U.S. fiduciaries have the authority to control all substantial
          decisions.     

An individual may, subject to certain exceptions, be deemed a resident of the
United States by virtue of being present in the United States for at least 31
days in the current calendar year and for an aggregate of at least 183 days
during the prior three year period ending in the current calendar year (counting
for such purposes all days present in the current calendar year, one-third of
the days present in the immediately preceding calendar year, and one-sixth of
the days present in the second preceding calendar year). The term "Non-U.S.
Holder" does not include individuals who were United States citizens within the
ten-year period immediately preceding the date of this Prospectus and whose loss
of United States citizenship had as one of its principal purposes the avoidance
of United States taxes.
    
The following summary deals only with common stock held as capital assets within
the meaning of Section 1221 of the Internal Revenue Code and does not deal with
special situations, such as those of dealers in securities or currencies,
financial institutions, life insurance companies, tax exempt organizations, or
persons holding common stock as a part of a hedging or conversion transaction or
a straddle.  Furthermore, the discussion below is based upon the provisions of
the Internal Revenue Code and Treasury regulations, administrative and judicial
decisions thereunder as of the date hereof, and such authorities may be
repealed, revoked or modified with possible retroactive effect so as to result
in federal income and estate tax consequences different from those discussed
below.     
    
PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISERS REGARDING THE
UNITED STATES FEDERAL, STATE, LOCAL AND NON-UNITED STATES INCOME AND OTHER TAX
CONSEQUENCES OF HOLDING AND DISPOSING OF SHARES OF COMMON STOCK.     


DIVIDENDS
    
If dividends are paid on the common stock, these payments will be treated as
dividends for United States federal income tax purposes to the extent of
CONSOL's current or accumulated earnings and profits as determined under U.S.
income tax principles.  The portion of a payment that exceeds such earnings and
profits will be treated as a return of capital to the extent of each Non-U.S.
Holder's tax basis in the common stock.  The portion of a payment that exceeds
such earnings and profits and tax basis will be treated as a gain from the sale
or other disposition of the common stock to the extent of such excess, with the
tax consequences described below under ".Sale of Common Stock."     

                                      90
<PAGE>
 
    
In general, any dividends (i.e., distributions to the extent of current or
accumulated earnings and profits for United States federal income tax purposes)
paid to a Non-U.S. Holder of common stock will be subject to United States
withholding tax at a 30% rate (or a lower rate prescribed by an applicable tax
treaty) unless the dividends are either (1) effectively connected with a trade
or business carried on by the Non-U.S. Holder within the United States or (2) if
certain income tax treaties apply, attributable to a permanent establishment in
the United States maintained by the Non-U.S. Holder.  For purposes of
determining whether tax is to be withheld at a 30% rate or at a lower rate as
prescribed by an applicable tax treaty, CONSOL will presume, consistent with
currently effective Treasury Regulations, that dividends paid to an address in a
foreign country are paid to a resident of such country absent knowledge that
such presumption is not warranted.  However, under United States Treasury
regulations applicable to dividends paid after December 31, 1999, a Non-U.S.
Holder of common stock would be required to satisfy applicable certification and
other requirements in order to claim the benefits of an applicable tax treaty.
Dividends effectively connected with a United States trade or business or
attributable to a United States permanent establishment generally will not be
subject to withholding tax (if the Non-U.S. Holder files certain forms,
including IRS Form 4224, or any successor form, with the payor of the dividend)
and generally will be subject to United States federal tax on a net income
basis, in the same manner as if the Non-U.S. Holder were a resident of the
United States.  In the case of a Non-U.S. Holder that is a corporation, such
dividend income so connected or attributable may also be subject to the branch
profits tax (which is generally imposed on a foreign corporation on the
repatriation from the United States of its effectively connected earnings and
profits subject to certain adjustments) at a 30% rate (or a lower rate
prescribed by an applicable income tax treaty).     

A Non-U.S. Holder that is eligible for a reduced rate of United States
withholding tax pursuant to an income tax treaty may obtain a refund of any
excess amounts currently withheld by filing an appropriate claim for refund with
the IRS.


SALE OF COMMON STOCK
    
In general, a Non-U.S. Holder will not be subject to United States federal
income tax on any gain recognized upon the disposition of common stock 
unless:     
    
     .    the gain is effectively connected with a trade or business carried on
          by the Non-U.S. Holder within the United States or, alternatively, if
          certain tax treaties apply, attributable to a permanent establishment
          in the United States maintained by the Non-U.S. Holder (and in either
          such case, the branch profits tax may also apply if the Non-U.S.
          Holder is a corporation),     
    
     .    in the case of a Non-U.S. Holder who is a nonresident alien individual
          and holds common stock as a capital asset, such individual is present
          in the United States for 183 days or more in the taxable year of
          disposition, and either (a) such individual has a "tax home" (as
          defined for United States federal income tax purposes) in the United
          States or (b) the gain is attributable to an office or other fixed
          place of business maintained by such individual in the United 
          States,     
    
     .    the Non-U.S. Holder is subject to tax pursuant to the provisions of
          the United States tax law applicable to certain United States
          expatriates, or     
    
     .    subject to the exception discussed below, CONSOL is or has been a
          United States real property holding corporation for United States
          federal income tax purposes (which CONSOL believes that it is) at any
          time within the shorter of the five-year period preceding such
          disposition or such Non-U.S. Holder's holding period.     
    
If CONSOL is or becomes a United States real property holding corporation, gains
realized upon a disposition of common stock by a Non-U.S. Holder that did not
directly or indirectly own more than 5% of the     

                                      91
<PAGE>
 
    
common stock during the shorter of the periods described above generally would
not be subject to United States federal income tax so long as the common stock
was "regularly traded" on an established securities market (within the meaning
of Section 897(c)(3) of the Internal Revenue Code and the Treasury regulations
promulgated under such section) at the time of the disposition.     


ESTATE TAX
    
Common stock owned or treated as owned by an individual who is not a citizen or
resident (as defined for United States federal estate tax purposes) of the
United States at the time of death will be includible in the individual's gross
estate for United States federal estate tax purposes unless an applicable estate
tax treaty provides otherwise, and therefore may be subject to United States
federal estate tax.     


BACKUP WITHHOLDING, INFORMATION REPORTING AND OTHER REPORTING REQUIREMENTS

CONSOL must report annually to the IRS the amount of dividends paid to, and the
tax withheld with respect to, each Non-U.S. Holder.  These reporting
requirements apply regardless of whether withholding was reduced or eliminated
by an applicable tax treaty.  Copies of this information also may be made
available under the provisions of a specific treaty or agreement with the tax
authorities in the country in which the Non-U.S. Holder resides or is
established.
    
United States backup withholding (which generally is imposed at the rate of 31%
on certain payments to persons that fail to furnish the information required
under the United States information reporting requirements) and information
reporting (other than reporting requirements described in the preceding
paragraph) generally will not apply to dividends paid on common stock to a Non-
U.S. Holder at an address outside the United States.     
    
The payment of proceeds from the disposition of common stock to or through a
United States office of a U.S. broker will be subject to information reporting
and United States backup withholding unless the owner, under penalties of
perjury, certifies among other things, its status as a Non-U.S. Holder, or
otherwise establishes an exemption.  The payment of proceeds from the
disposition of common stock to or through a non-U.S. office of a U.S. or non-
U.S. broker generally will not be subject to backup withholding and information
reporting, except as noted below.  In the case of proceeds from the disposition
of common stock paid to or through a non-United States office of a U.S. broker,
or a non-U.S. broker that is:     
    
     .    a United States person,     
    
     .    a "controlled foreign corporation" for United States federal income
          tax purposes, or     
    
     .    a foreign person 50% or more of whose gross income for a specified
          three-year period is effectively connected with a United States trade
          or business, information reporting (but not backup withholding) will
          apply unless the broker has documentary evidence in its files that the
          owner is a Non-U.S. Holder (and the broker has no actual knowledge to
          the contrary).     

Backup withholding is not an additional tax.  Any amounts withheld under the
backup withholding rules from a payment to a Non-U.S. Holder can be refunded or
credited against the Non-U.S. Holder's United States federal income tax
liability, if any, provided that the required information is furnished to the
IRS.

The underwriting agreement provides that if the underwriters take any of the
shares set forth in the table above, then they must take all of these shares.
No underwriter is obligated to take any shares allocated to a defaulting
underwriter except under the limited circumstances described in the underwriting
agreement.     
    
The underwriters are offering the shares of common stock, subject to the prior
sale of such shares, and when, as and if such shares are delivered to and
accepted by them.  The underwriters will initially offer to sell shares to the
public at the initial public offering price set forth on the cover page of this
prospectus.  The underwriters may sell shares to securities dealers at a
discount of up to $   per share from the initial public offering price.  Any
such securities dealers may resell shares to certain other brokers or dealers at
a discount of up to $   per share from the initial public offering price.  After
the initial public offering, the underwriters may vary the public offering price
and other selling terms.     
    
If the underwriters sell more shares than the total number set forth in the
table above, the underwriters have the option to buy up to an additional
3,390,000 shares of common stock from CONSOL to cover such sales.  They may
exercise this option during the 30-day period from the date of this prospectus.
If any shares are purchased pursuant to this option, the underwriters will
purchase shares in approximately the same proportion as set forth in the table
above.     
    
The following table shows the per share and total underwriting discounts and
commissions that CONSOL will pay to the underwriters.  These amounts are shown
assuming both no exercise and full exercise of the underwriters' option to
purchase additional shares.

The underwriters may purchase and sell shares of common stock in the open market
in connection with this offering.  These transactions may include short sales,
stabilizing transactions and purchases to cover positions created by short
sales.  Short sales involve the sale by the underwriters of a greater number of
shares than they are required to purchase in the offering.  Stabilizing
transactions consist of certain bids or purchases made for the purpose of
preventing or slowing a decline in the market price of the common stock while
the offering is in progress.  The underwriters may also impose a penalty bid,
which means that an underwriter must repay to the other underwriters a portion
of the underwriting discount received by it.  An underwriter may be subject to a
penalty bid if the representatives of the underwriters, while engaging in
stabilizing or short covering transactions, repurchase shares sold by or for the
account of that underwriter.  These activities may stabilize, maintain or
otherwise affect the market price of the common stock.  As a result, the price
of the common stock may be higher than the price that otherwise might exist in
the open market.  If the underwriters commence these activities, they may
discontinue them at any time.  The underwriters may carry out these transactions
on the New York Stock Exchange, in the over-the-counter market or 
otherwise.     
    
CONSOL estimates that the total expenses of this offering, excluding
underwriting discounts and commissions, will be $   .     
    
CONSOL has agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933.     
    
CONSOL, Rheinbraun, DuPont and certain directors and senior officers of CONSOL
have agreed with the underwriters not to dispose of or hedge any of their common
stock (or securities convertible into or exchangeable for shares of common
stock) for a period of 180 days after the date of this prospectus, except with
the prior written consent of J.P. Morgan Securities Inc.  This agreement does
not apply to any of CONSOL's employee benefit plans existing on or outstanding
as of the date of this prospectus.     
    
At CONSOL's request, the underwriters have reserved shares of common stock for
sale to certain directors, officers, employees and retirees of CONSOL who have
expressed an interest in participating in the offering.  CONSOL expects these
persons to purchase no more than 5% of the common stock offered in the offering.
The number of shares available for sale to the general public will be reduced to
the extent such persons purchase such reserved shares.  The underwriters will
offer unpurchased reserved shares to the general public on the same basis as the
other offered shares.     
    
CONSOL has applied to list the common stock on the New York Stock Exchange under
the trading symbol "CNX."     
    
There has been no public market for the common stock prior to this offering.
CONSOL and the underwriters will negotiate the initial offering price.  In
determining the price, CONSOL and the underwriters expect to consider a number
of factors in addition to prevailing market conditions, including:     
    
     .    the history of and prospects for the coal industry,     
    
     .    an assessment of CONSOL's management;     
    
     .    CONSOL's present operations;     
    
     .    CONSOL's historical results of operations;     
    
     .    the trend of CONSOL's revenues and earnings; and     

                                      94
<PAGE>
 
    
     .    CONSOL's earnings prospects.     
    
CONSOL and the underwriters will consider these and other relevant factors in
relation to the prices of similar securities of generally comparable companies.
Neither CONSOL nor the underwriters can assure investors that an active trading
market will develop for the common stock, or that the common stock will trade in
the public market at or above the initial offering price.     
    
The underwriters and their affiliates have in the past engaged in commercial and
investment banking transactions with CONSOL and its affiliates in the ordinary
course of business.  They may continue to do so in the future.     


                                 LEGAL MATTERS

    
The validity of the common stock will be passed upon for CONSOL by Thelen Reid &
Priest LLP, New York, New York.  Certain legal matters in connection with the
offering will be passed upon for the Underwriters by Davis Polk & Wardwell, New

                                   GLOSSARY

    
Accessible Reserves.  Coal adjacent to and accessible by an active mine and that
is anticipated to be mined by that active mine but has not yet been assigned.
In some cases, accessible reserves can be accessed by more than one mine.     
    
Assigned Reserves.  Coal that is designated to be mined by a specific mine.     

Anthracite.  The highest rank of economically usable coal with moisture content
less than 15% by weight and heating value as high as 15,000 Btus per pound.  It
is jet black with a high luster.  It is mined primarily in Pennsylvania.

Ash.  Impurities consisting of iron, alumina and other incombustible matter that
are contained in coal. Since ash increases the weight of coal, it adds to the
cost of handling and can affect the burning characteristics of coal.

Bituminous Coal.  The most common type of coal with moisture content less than
20% by weight and heating value of 10,500 to 14,000 Btus per pound.  It is dense
and black and often has well-defined bands of bright and dull material.

British Thermal Unit ("Btu").  A measure of the energy required to raise the
temperature of one pound of water one degree Fahrenheit.

Coal Seam.  Coal deposits occur in layers.  Each such layer is called a "seam."

Continuous Mining.  A form of underground room-and pillar mining, which involves
the excavation of a series of "rooms" into the coal seam leaving "pillars" or
columns of coal to help support the mine roof.  A specialized cutting machine,
the continuous miner, mechanizes the extraction procedure.  Continuous miners
tear the coal from the seam and load it onto conveyors or into shuttle cars in a
continuous operation.

Longwall Mining.  A form of underground mining in which two sets of parallel
entries, which can be up to 1,000 feet apart, are joined together at their far
ends by a crosscut, called the longwall.  The longwall machine consists of a
rotating drum that moves back and forth across the longwall.  The loosened coal
falls onto a conveyor for removal from the mine.

Metallurgical Coal.  The various grades of coal suitable for carbonization to
make coke for steel manufacture.  Also known as "met" coal, it possesses four
important qualities: volatility, which affects coke yield; the level of
impurities, which affects coke quality; composition, which affects coke
strength; and basic characteristics, which affect coke oven safety.  Met coal
has a particularly high Btu, but low ash content.

Nitrogen Oxide (NO\\2\\).  A gas formed in high temperature environments such as
coal combustion.  It is reported to contribute to ground level ozone and
visibility degradation.

Preparation Plant.  Usually located on a mine site, although one plant may serve
several mines.  A preparation plant is a facility for crushing, sizing and
washing coal to prepare it for use by a particular customer.  The washing
process has the added benefit of removing some of the coal's sulfur content.

Probable Reserves.  Reserves for which quantity and/or quality are computed from
information similar to that used for proved reserves, but the sites for
inspection, sampling, and measurement are farther apart or are otherwise less
adequately spaced.  The degree of assurance, although lower than that for proved
reserves, is high enough to assume continuity between points of observation.

                                      96

Proved Reserves.  Reserves for which (a) quantity is computed from dimensions
revealed in outcrops, trenches, workings or drill holes; grade and/or quality
are computed from the results of detailed sampling and (b) the sites for
inspection, sampling and measurement are spaced so closely and the geologic
character is so well defined that size, shape, depth and mineral content of
reserves are well-established.
    
Reserves.  That part of a mineral deposit which could be economically and
legally extracted or produced at the time of the reserve determination.     

Scrubber (flue gas desulfurization unit).  Any of several forms of
chemical/physical devices which operate to neutralize sulfur compounds formed
during coal combustion.  These devices combine the sulfur in gaseous emissions
with other chemicals to form inert compounds, such as gypsum, which must then be
removed for disposal.

Steam Coal.  Coal used by power plants and industrial steam boilers to produce
electricity or process steam.  It generally is lower in Btu heat content and
higher in volatile matter than metallurgical coal.

Subbituminous Coal.  Dull, black coal that ranks between lignite and bituminous
coal.  Its moisture content is between 20% and 30% by weight, and its heat
content ranges from 7,800 to 9,500 Btus per pound of coal.

Sulfur.  One of the elements present in varying quantities in coal.  Sulfur
dioxide (S0\\2\\) is produced as a gaseous by-product of coal combustion.

Tons.  A "short" or net ton is equal to 2,000 pounds.  A "long" or British ton
is 2,240 pounds; a "metric"  ton is approximately 2,205 pounds.  The short ton
is the unit of measure referred to in this document.
    
Unassigned Reserves.  Coal that has not yet been designated for mining by a
specific operation but is part of the proved and probable reserve reported by
the company at year-end.

                        REPORT OF INDEPENDENT AUDITORS


Board of Directors and Stockholders
CONSOL Energy Inc.

We have audited the consolidated balance sheets of CONSOL Energy Inc. and
subsidiaries (CONSOL) as of December 31, 1996 and 1997, and the related
consolidated statements of income, stockholders' equity and cash flows for each
of the three years in the period ended December 31, 1997.  These financial
statements are the responsibility of CONSOL's management.  Our responsibility is
to express an opinion on these financial statements based on our audit.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of CONSOL
at December 31, 1996 and 1997, and the consolidated results of their operations
and their cash flows for each of the three years in the period ended December
31, 1997 in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                            (DOLLARS IN THOUSANDS)


NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies of CONSOL Energy Inc. and
subsidiaries (CONSOL) is presented below.  These, together with the other notes
that follow, are an integral part of the consolidated financial statements.

BASIS OF CONSOLIDATION

The consolidated financial statements include the accounts of majority-owned
subsidiaries.  Investments in affiliates owned 20 percent to 50 percent are
accounted for under the equity method.  Investments in non-corporate joint
ventures, for which CONSOL owns undivided interests in the assets and
liabilities, are consolidated on a pro rata basis.  Other securities and
investments are carried at cost.  All significant intercompany transactions and
accounts have been eliminated in consolidation.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

CASH AND CASH EQUIVALENTS

Cash and cash equivalents include cash on hand and in banks as well as all
highly liquid short-term securities with a maturity of three months or less at
the time of purchase.  Overdrafts representing outstanding checks in excess of
funds on deposit are classified as accounts payable.

MARKETABLE SECURITIES
    
Marketable securities are considered available-for-sale and consist primarily of
financial instruments for which the yield (dividend or interest) is established
periodically through a market auction mechanism.  These investments are readily
convertible to cash and are stated at cost plus accrued interest, which
approximates fair value, due to the liquidity provided by the auction process.
At December 31, 1997, these securities generally had no contractual maturity
date but had yield reset periods of less than 30 days.  During the three years
ended December 31, 1997, all transactions in the portfolio were at par resulting
in no realized gains or losses from the contractual yields.     

INVENTORIES

Inventories are stated at the lower of cost or market.

Cost is determined by the last-in first-out (LIFO) method for 54% and 46% of
coal inventories at December 31, 1996 and December 31, 1997, respectively.  The
cost of coal inventories not on LIFO is determined by the first-in, first-out
(FIFO) method.  Coal inventory costs include labor, supplies, equipment costs,
overhead, and other related costs.  The cost of merchandise for resale is
determined by the LIFO method.  The cost of supplies inventory is determined by
the average cost method.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment is carried at cost.  Expenditures, which extend
the useful lives of existing plant and equipment, are capitalized.  Interest
costs applicable to major asset additions are capitalized during the
construction period.  Coal exploration costs are expensed as incurred.
Development costs applicable to the opening of new coal mines and certain mine
expansion projects are capitalized.  Costs of additional mine

however, the costs of additional airshafts and new portals are capitalized.

Maintenance, repairs and minor renewals are expensed as incurred.  When
properties are retired or otherwise disposed, the related cost and accumulated
depreciation are removed from the respective accounts and any profit or loss on
disposition is credited or charged to income.

Depreciation of plant and equipment, including assets leased under capital
leases, is provided on the straight-line method over their estimated useful
lives or lease terms.  Depletion of coal lands and amortization of mine
development costs are computed using the units-of-production method over the
estimated recoverable tons.

ADVANCE MINING ROYALTIES

Advance mining royalties are advance payments made to lessors under terms of
mineral lease agreements that are recoupable against future production.  These
advance payments are deferred and charged against income as the coal reserves
are mined.

IMPAIRMENT OF LONG-LIVED ASSETS
    
Impairment of long-lived assets is recorded when indicators of impairment are
present and the undiscounted cash flows estimated to be generated by those
assets are less than the assets' carrying value.  The carrying value of the
assets are then reduced to their estimated fair value which is usually measured
based on an estimate of future discounted cash flows.     

INCOME TAXES

The provision for income taxes has been determined under Statement of Financial
Accounting Standards No. 109, which requires use of the asset and liability
approach to accounting for income taxes.  Under this approach, deferred taxes
represent the future tax consequences expected to occur when the reported
amounts of assets and liabilities are recovered or paid.  The provision for
income taxes represents income taxes paid or payable for the current year and
the change in deferred taxes during the year.  Deferred taxes result from
differences between the financial and tax bases of the company's assets and
liabilities and are adjusted for changes in tax rates and tax laws when changes
are enacted.  Valuation allowances are recorded to reduce deferred tax assets
where it is more likely than not that a deferred tax benefit will not be
realized.

PNEUMOCONIOSIS BENEFITS

CONSOL is required by federal and state statutes to provide benefits to
employees for awards related to coal workers' pneumoconiosis.  CONSOL is self-
insured for these benefits.  Provisions are made for estimated benefits based on
annual evaluations prepared by outside actuaries.

MINE CLOSING COSTS

Estimated final mine closing and perpetual care costs are accrued over the
productive life of mines on a units of production basis.

WORKERS' COMPENSATION

CONSOL is primarily self-insured for workers' compensation.  Annual provisions
are made for the estimated liability for awarded and pending claims.

RECLAMATION

Generally, CONSOL records a liability for the estimated costs to reclaim land as
the acreage is disturbed during the ongoing surface mining process.

REVENUE RECOGNITION

Coal sales are recorded at contract prices when title passes to the customer.
Generally, for domestic sales, this occurs when coal is loaded onto
transportation vehicles at mine or offsite storage locations.  For most export
sales, this occurs when coal is loaded onto marine vessels at terminal
locations.  Industrial supplies and equipment sales are recorded when the
products are shipped.

RECLASSIFICATIONS

Certain reclassifications of prior years' data have been made to conform to 1997
classifications.


NOTE 2 - ACQUISITIONS AND DISPOSITIONS
    
On December 1, 1995, CONSOL sold Reid Holding, Inc. and Oakwood Gathering, Inc.
for $77,483.  These operations consist mainly of coal bed methane reserve
properties and gas collection facilities.  The carrying amount of assets sold in
connection with this sale amounted to $89,196 resulting in a pre-tax loss of
$11,713.  CONSOL continues to serve as operator for these companies, and retains
certain rights for participation in future gas operations.  The results of these
operations were not material to the 1995 consolidated financial statement.     

On November 20, 1995, CONSOL acquired the Greene Hill Coal Company from Realty
Company of Pennsylvania, a coal reserve holding subsidiary of Pennsylvania Power
& Light Company for $52,520.  The acquisition included approximately 183 million
clean recoverable tons of Pittsburgh seam coal in Greene County, Pennsylvania.
This acquisition has been accounted for under the purchase method and
accordingly, the purchase price has been allocated to the assets acquired, based
on the fair values at the date of the acquisition.  CONSOL's financial
statements include the results of the acquisition on a consolidated basis
effective November 20, 1995.

NOTE 14 -- EMPLOYEE BENEFIT PLANS

PENSION PLANS

CONSOL has non-contributory defined benefit plans covering substantially all
employees not covered by multi-employer retirement plans.  The benefits for
these plans are based primarily on years of service and employees' pay near
retirement.  CONSOL's funding policy is consistent with the funding requirements
of federal law and regulations.

Net pension charges for defined benefit plans include the following components:

excludes the additional pension liability of $1,201 in 1996 and $551 in 1997
(included in Other Deferred Credits and Other Liabilities) needed to meet the
minimum liability requirements.

The projected benefit obligation was determined using a discount rate of 7.25%
in 1996 and in 1997.  The assumed long-term rate of compensation increase was 5%
in 1996 and in 1997.  The assumed long-term rate of return on plan assets was 9%
in all years.  Plan assets consist principally of common stocks and U.S.
government obligations.

Certain subsidiaries of CONSOL are required under the National Bituminous Coal
Wage Agreement (NBCWA) of 1993 with the United Mine Workers of America (UMWA) to
pay amounts to the UMWA Pension Trusts based principally on hours worked by UMWA
represented employees.  These multi-employer pension trusts provide benefits to
eligible retirees through a defined benefit plan.  Amounts charged to expense
for these benefits were $7,166 in 1995, $6,441 in 1996 and $5,831 in 1997.  The
Employee Retirement Income Security Act of 1974 (ERISA) as amended in 1980,
imposes certain liabilities on contributors to multi-employer pension plans in
the event of a contributor's withdrawal from the plan.  The withdrawal liability
would be calculated based on the contributor's proportionate share of the plan's
unfunded vested liabilities.

The Coal Industry Retiree Health Benefit Act of 1992 (The Act) created two
multi-employer benefit plans:  (1) the United Mine Workers of America Combined
Benefit Fund (The Combined Fund) into which the former UMWA Benefit Trusts were
merged, and (2) the 1992 Benefit Fund.  CONSOL subsidiaries account for required
contributions to these multi-employer trusts as expense when incurred.

The Combined Fund provides medical and death benefits for all beneficiaries of
the former UMWA Benefit Trusts who were actually receiving benefits as of July
20, 1992.  The Act provides for the assignment of beneficiaries to former
employers and the allocation of unassigned beneficiaries (referred to as
orphans) to companies using a formula set forth in The Act.  The Act requires
that responsibility for funding the benefits to be paid to beneficiaries be
assigned to their former signatory employers or related companies.  Amounts
charged to expense for the Combined Fund were $22,730 in 1995, $25,828 in 1996
and $32,980 in 1997.

The 1992 Benefit Fund provides medical and death benefits to orphan UMWA-
represented members eligible for retirement on February 1, 1993, and who
actually retired between July 20, 1992 and September 30, 1994.  Amounts charged
to expense for the 1992 Benefit Fund were $1,855 in 1995, $3,269 in 1996 and
$5,564 in 1997.

The UMWA 1993 Benefit Plan is a defined contribution plan that was created as
the result of negotiations for the NBCWA of 1993.  This plan provides health
care benefits to orphan UMWA retirees who are not eligible to participate in the
Combined Fund, the 1992 Benefit Fund, or whose last employer signed the NBCWA of
1993 and subsequently goes out of business.  Contributions to the trust are
fixed at ten cents per hour worked by UMWA represented employees.  The NBCWA of
1993 specifies that benefits provided under this plan are only for the duration
of the contract.  Amounts charged to expense for the UMWA 1993 Benefit Plan were
$956 in 1995, $857 in 1996 and $779 in 1997.

A new five-year labor agreement was reached in December 1997 and will be
effective from January 1, 1998 through December 31, 2002.  This agreement
replaces the National Bituminous Coal Wage Agreement (NBCWA) of 1993.

INVESTMENT PLAN

CONSOL has an Investment Plan available to all domestic, non-represented
employees.  CONSOL matches employee contributions for an amount up to 6% 
of the employee's base pay.  Amounts charged to expense were $12,170 in 1995,
$11,324 in 1996 and $11,372 in 1997.


LONG-TERM DISABILITY

CONSOL has a Long-Term Disability Plan available to all full-time salaried
employees.  The benefits for this plan are based on a percentage of monthly
earnings, offset by all other income benefits available to the disabled.
Liabilities (net of Plan Assets) included in Deferred Credits and Other
Liabilities - Other amounted to $18,960 and $22,342 at December 31, 1996, and
December 31, 1997, respectively.  The liabilities were determined using a
discount rate of 7.25% in 1996 and 1997.  Amounts charged to expense were $1,740
in 1995, $2,988 in 1996 and $8,449 in 1997.


COAL WORKERS' PNEUMOCONIOSIS (CWP)

CONSOL is liable under the Federal Coal Mine Health and Safety Act of 1969, as
amended, for medical and disability benefits to employees and their dependents
resulting from occurrences of coal workers' pneumoconiosis disease.  CONSOL is
also liable under various state statutes for pneumoconiosis benefits.  CONSOL
provides for these claims through a self-insurance program.

CONSOL employs the projected unit credit method to determine the CWP liability
and expense.  Under this method, the costs determined by the actuarial study are
being amortized over the employees' requisite service period.  Actuarial gains
and losses are being amortized over the remainder of the service life of the
employees which approximates 15.4 years.

Coal Workers' Pneumoconiosis cost included the following components:

NOTE 15 - POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

Certain subsidiaries of CONSOL provide medical and life insurance benefits to
retired employees not covered by the Coal Industry Retiree Health Benefit Act of
1992.  Substantially all employees may become eligible for these benefits if
they have worked ten years and attained age 55.  The associated plans are
unfunded.  The medical plan contains certain cost sharing and containment
features, such as deductibles, coinsurance, health care networks and
coordination with Medicare.

A 7.5% annual rate of increase in per capita cost of covered health care
benefits was assumed for 1997, gradually decreasing to 4.5% in 2003, and
remaining level thereafter. The health care cost trend rate assumption has a
significant effect on the amount of the obligation and periodic cost reported.
An increase in the assumed health care cost trend rate by 1% in each year would
increase the accumulated postretirement benefit obligation as of December 31,
1997 by $84,920 and increase the aggregate of the service and interest cost
component of net periodic postretirement benefit cost for 1997 by $8,085.

The National Bituminous Coal Wage Agreement of 1993 included additional cost
containment features, including increased deductibles, pre-certification
requirements, and the implementation of a health care network, which reduced the
obligation for future represented retirees.  This plan amendment resulted in an
unrecognized reduction in prior service cost of $49,459, which is being
amortized over the average remaining years of service to full eligibility of
those plan participants active at the date of the plan amendment.  Effective
July 1, 1994, the benefit plans for non-represented employees were changed
similarly which reduced the obligation for current and future non-represented
retirees.  This plan amendment resulted in an unrecognized reduction in prior
service cost of $24,153, which is being amortized over the average remaining
years of service to full eligibility of those plan participants active at the
date of the plan amendment.

receivable from utilities were $134,711 and $137,857, respectively, and from
steel and coke producers were $62,743 and $47,015, respectively. Credit is
extended based on an evaluation of the customer's financial condition, and
generally collateral is not required. Credit losses consistently have been
minimal.

CONSOL is committed under several long-term contracts to supply coal that meets
certain quality requirements at specified prices. These prices are generally
adjusted based on indices. Quantities sold under some of these contracts may
vary from year to year within certain limits at the option of the customer.

Sales (including spot sales) to a major customer were $302,968 in 1995, $318,899
in 1996 and $357,605 in 1997. As of December 31, 1996 and 1997, accounts
receivable from this customer were $35,146 and $31,818, respectively.

In 1995, 1996 and 1997, CONSOL U.S. operations had export sales, principally to
Canadian and Western European customers, of $359,370, $357,854 and $325,544,
respectively.


NOTE 19 - FAIR VALUES OF FINANCIAL INSTRUMENTS

The following methods and assumptions were used to estimate the fair value of
financial instruments:

Cash and cash equivalents  The carrying amount reported in the balance sheet for
cash and cash equivalents approximates its fair value due to the short maturity
of these instruments.

Marketable securities  The carrying value of marketable securities approximates
fair value based on impending auction dates and routine trading at par value for
those or similar investments.

Short-term notes payable  The carrying amount reported in the balance sheet for
short-term notes payable approximates its fair value due to the short-term
maturity of these instruments.

Long-term debt  The fair values of long-term debt are estimated using discounted
cash flow analyses, based on CONSOL's current incremental borrowing rates for
similar types of borrowing arrangements.

The carrying amounts and fair values of financial instruments are as follows:

NOTE 20 - COMMITMENTS AND CONTINGENT LIABILITIES
    
CONSOL has various purchase commitments for materials, supplies and items of
permanent investment incidental to the ordinary conduct of business.  Such
commitments are not at prices in excess of current market.     
    
CONSOL is subject to various lawsuits and claims with respect to such matters as
personal injury, damage to property, governmental regulations including
environmental remediation, and other actions, arising out of the normal course
of business.  The costs of mine closing and reclamation are accrued over the
productive life of the mine.  In addition, CONSOL has accrued $3,275 in other
liabilities for remediation of a waste disposal site.  In the opinion of
management, the ultimate liabilities resulting from such lawsuits and claims
will not materially affect CONSOL.     

A public utility filed suit against CONSOL alleging breach of a long-term coal
supply contract based upon CONSOL's refusal to agree to price reductions in the
price for coal under the contract's "gross inequities" clause.  Damages claimed,
including interest, are approximately $190 million.  Discovery is in progress,
and the case is set for trial October 5, 1998.  CONSOL is vigorously defending
the suit.  Management believes that the claims are without merit, and,
accordingly, CONSOL has not accrued any liability associated with the action.

CONSOL received from a group of public utilities, two notices of intent to
submit certain price disputes to arbitration pursuant to a 1987 coal sales
contract.  The notices claim that the utilities have been overcharged by
approximately $40 million for coal under the price adjustment clause of the
contract.  In accordance with contract procedure, CONSOL submitted its response
asserting that the price adjustments were made in conformity with the contract.
The parties have not yet submitted their positions to an arbitrator.  Management
believes that the claims are without merit, and, accordingly, CONSOL has not
accrued any liability associated with this proceeding.

A subsidiary has a long-term sales contract to supply coal to a group of public
utilities.  This contract was conditioned on the purchase of the subsidiary that
will supply a portion of the contracted coal.  By agreement between the parties,
a portion of the amounts payable by the group of public utilities includes debt
service (long-term debt and capital lease obligations) that the company is
obligated to pay for the benefit of the group of public utilities, which has
severally guaranteed to the holders the discharge of the long-term debt and
capital lease obligations.  Accordingly, that portion of the contract receivable
has been assigned to reduce the unpaid amounts of long-term debt and capital
lease obligations (which aggregated $81,189 at December 31, 1997), as such
amounts are funded and guaranteed by, and are under the responsibility and
control of, the group of public utilities.

*    Proved and probable coal reserves are the equivalent of "demonstrated
reserves" under the coal resource classification system of the U.S. Geological
Survey. Generally, these reserves would be commercially minable at year-end
prices and cost levels, using current technology and mining practices.

The coal reserves are located in nearly every major coal-producing region in
North America.  At December 31, 1997, 858 million tons were assigned to mines
either in production or under development.  The proved and probable reserves at
December 31, 1997 include 4,020 million tons of steam coal, of which
approximately 15 percent has a sulfur content equivalent to less than 1.2 pounds
sulfur dioxide per million British thermal unit (Btu), and an additional 15
percent has a sulfur content equivalent to between 1.2 and 2.5 pounds sulfur
dioxide per million Btu.  The reserves also include 756 million tons of
metallurgical coal, of which approximately 65 percent has a sulfur content
equivalent to less than 1.2 pounds sulfur dioxide per million Btu, and the
remaining 35 percent has a sulfur content equivalent to between 1.2 and 2.5
pounds sulfur dioxide per million Btu.  A significant portion of this
metallurgical coal can also serve the steam coal market.

                             (DOLLARS IN THOUSANDS)     



NOTE 1 - BASIS OF PRESENTATION

The Company considers that all adjustments (all of which are normal recurring
accruals) necessary for a fair statement of financial position and results of
operations for these periods have been made; however, results for such interim
periods are subject to year-end audit adjustments.  Results for such interim
periods are not necessarily indicative of results for a full year.

NOTE 2 - ACQUISITION
    
On September 22, 1998, CONSOL purchased 100% of the outstanding stock of the
Rochester and Pittsburgh Coal Company (R&P) for $149,683.  The acquisition has
been accounted for as a purchase and, accordingly, the operating results of R&P
have been included in the Company's consolidated financial statements since the
date of acquisition.  Pro forma revenues were $646,015 and $629,540 for the
third quarter 1998 and 1997 respectively, and were $1,972,247 and $1,893,997 for
the nine months ended September 30, 1998 and 1997 respectively.  Pro forma net
income would not materially change for these periods.     
    
NOTE 3 - SUBSEQUENT EVENTS     
    
On September 14, 1998, the Company entered into a definitive agreement to
purchase 47,000 shares of Class A Common Stock from DuPont and affiliated
companies at a price of $500,000.  The closing of the transaction occurred on
November 5, 1998.  The Board of Directors agreed that prior to the closing,
CONSOL would pay the pro rata annual dividend based on to-date results for the
days of 1998 elapsed prior to the payment of the purchase price of the shares.
The pro rata dividend of $59,677 was paid on November 5, 1998.  On December 28,
1998, and additional dividend of $20,323 was paid, bringing the total dividends
paid in 1998 to $80,000.  The Company issued commercial paper in November 1998
in order to finance, together with other available funds, the purchase of the
shares, the payment of the dividend and the acquisition of R&P and the
refinancing of certain indebtedness incurred by R&P.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

  CONSOL's Certificate of Incorporation and By-Laws provide, in part, that
CONSOL shall indemnify its directors, officers, employees and agents to the
fullest extent permitted by the Delaware General Corporation Law (the "DGCL").

  The DGCL permits Delaware corporations to indemnify their directors and
officers against all reasonable expenses incurred in the defense of any lawsuit
to which they are made parties by reason of being directors or officers, in
cases of successful defense, and against such expenses in other cases, subject
to specified conditions and exclusions.  Such indemnification is not exclusive
of any other rights to which those indemnified may be entitled under any by-law,
agreement, vote of stockholders or otherwise.

  The DGCL contains a provision eliminating the personal liability of a director
to a corporation or its stockholders for monetary damages for breach of, or
failure to perform, any duty resulting solely from his status as a director,
except with respect to (a) a willful failure to deal fairly with the corporation
or its stockholders where a director has a material conflict of interest, (b) a
violation of criminal law unless the director had reasonable cause to believe
his conduct was lawful, (c) a transaction yielding an improper personal profit,
and (d) willful misconduct. The foregoing statute also is applicable to
situations wherein a director has voted for, or assented to the declaration of,
a dividend, repurchase of shares, distribution, or the making of a loan to an
officer or director, in each case where the same occurs in violation of
applicable law.

  CONSOL has purchased directors' and officers' liability insurance covering
certain liabilities incurred by its directors in connection with the performance
of their duties.

  The Underwriting Agreement filed herewith as Exhibit 1 contains provisions by
which the Underwriters agree to indemnify CONSOL, each person who controls
CONSOL within the meaning of Section 15 of the Securities Act or Section 20 of
the Securities Exchange Act of 1934, as amended, each director of CONSOL 

                                     II-1

and each officer of CONSOL who signs the Registration Statement with respect to
information furnished in writing by the Underwriters for use in the Registration
Statement.

ITEM 17. UNDERTAKINGS.

  (a) The undersigned registrant hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.

  (b) Insofar as indemnification for liabilities arising under the Securities
Act of 1933, may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

  (c) The undersigned registrant hereby undertakes that:

      (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.

     (2) For the purpose of determining any liability under the Securities Act
of 1933, each post-effective amendment that contains a form of prospectus shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

                                LOANS AND NOTES

     SECTION 3.1    Borrowing Procedure.  By giving notice to the Bank on or
                    -------------------                                     
before 12:00 noon, New York time, the Borrower may from time to time irrevocably
request, on not less than three (or same-day in the case of a Base Rate Loan)
nor more than five Business Days' notice, that a Borrowing be made by the Bank
in an aggregate amount equal to the lesser of (i) a minimum amount of $500,000
and an integral multiple of $100,000 in excess thereof, or (ii) the unused
amount of the Commitment then available pursuant to Section 2.1. Such notice may
                                                    -----------                 
be oral and shall be confirmed in writing on or before the first Business Day
following such request by delivering a Loan Request to the Bank.  Subject to the
terms and conditions of this Agreement, each Borrowing shall be made on the
Business Day specified in the Loan Request therefor.  On such Business Day and
subject to such terms and conditions, the Bank shall provide the Borrower with
funds, on or before 11:00 a.m., New York time (or 3:00 p.m., New York time, in
the case of a Base Rate Loan), in an amount equal to such Loan Request by
transferring same day or immediately available funds to such account as the
Borrower shall specify from time to time by notice to the Bank.

     SECTION 3.2    Note.  All Loans made by the Bank shall be evidenced by a
                    ----                                                     
Note payable to the order of the Bank in a maximum principal amount equal to the
Bank's original Total Commitment Amount.  The Borrower hereby irrevocably
authorizes the Bank to make (or cause to be made) appropriate notations on the
grid attached to the Bank's Note (or on a continuation of such grid attached to
any such Note and made a part thereof), which notations, if made, shall
evidence, inter alia, the date of, the outstanding principal of, and the
          ----- ----                                                    
interest rate (including any conversions thereof pursuant to Section 4.2) and
                                                             -----------     
Interest Period applicable to, the Loans evidenced thereby.  Any such notations
on any such grid (and on any such continuation) indicating the outstanding
principal amount of the Bank's Loans shall be rebuttable presumptive evidence of
the principal amount thereof owing and unpaid, but the failure to record any
such amount on such grid (or on such continuation) shall not limit or otherwise
affect the obligations of the Borrower hereunder or under such Note to make
payments of principal of or interest on such Loans when due.

     SECTION 3.3    Principal Payments and Prepayments.  The Borrower will repay
                    ----------------------------------                          
the outstanding principal amount of the Notes on the Commitment Termination
Date.  In addition, the Borrower:

          (a) may make a voluntary prepayment in part in an aggregate principal
     amount of not less than $500,000 and an integral multiple of $100,000 in
     excess thereof, or in full of the outstanding principal amount of the Notes
     from time to time

                                      17
<PAGE>
 
     at any time, in each case upon at least three Business Days' prior notice
     (or same day notice in the case of a Base Rate Loan) to the Bank;

          (b) shall, on each date when any reduction in the Total Commitment
     Amount shall become effective pursuant to Section 2.2, make a mandatory
                                               -----------                  
     prepayment of the Notes equal to the excess, if any, of the outstanding
     principal amount of all Loans over the Total Commitment Amount as so
     reduced; and

          (c) shall, on each date when the sum of the aggregate principal amount
     of all Loans outstanding plus the Commercial Paper Indebtedness exceeds the
     Total Commitment Amount, make a mandatory prepayment of the then aggregate
     outstanding principal amount of all Loans in an aggregate amount equal to
     such excess.

Each prepayment of a Note made pursuant to this Section shall be without premium
or penalty, except as may be required by Section 4.5. All interest accrued on
                                         -----------                         
the principal amount of Notes prepaid shall be paid on the date of such
prepayment.  No prepayment of principal of the Notes pursuant to clause (a) or
                                                                        ---   
(c) above prior to the Commitment Termination Date shall cause a reduction in
- ---                                                                          
the Total Commitment Amount.

     Each prepayment of the Notes shall, except as the Borrower may otherwise
have notified the Bank, be applied, to the extent of such prepayment:

          (a) first, to the principal amount thereof being maintained as a Base
     Rate Loan;

          (b) second, to the principal amount thereof being maintained as a CD
     Rate Loan; and

          (c) third, to the principal amount thereof being maintained as a LIBO
     Rate Loan.

     SECTION 3.4    Interest.  The Borrower agrees to pay interest on the
                    --------                                             
principal amount of the Notes from time to time unpaid prior to and at Maturity
at a rate per annum:

          (a) on that portion of the outstanding principal amount thereof
     maintained from time to time as a Base Rate Loan, equal to the sum of the
     Base Rate from time to time most recently announced plus the Applicable
     Margin per annum,

          (b) on that portion of the outstanding principal amount thereof
     maintained from time to time as one or more CD Rate Loans during each
     applicable Interest Period, equal to the sum of the CD Rate (Reserve
     Adjusted) for such Interest Period plus the Applicable Margin per annum,
     and

                                      18
<PAGE>
 
          (c) on that portion of the outstanding principal amount thereof
     maintained from time to time as one or more LIBO Rate Loans during each
     applicable Interest Period, equal to the sum of the LIBO Rate (Reserve
     Adjusted) for such Interest Period plus the Applicable Margin per annum.

     SECTION 3.5    Post-Maturity Rates.  After the Maturity of all or any
                    -------------------                                   
portion of the principal amount of the Loans or after any other monetary
Liabilities shall have become due, the Borrower shall pay interest (after as
well as before judgment) on the principal amount of all types of Loans so
matured or on such other monetary Liabilities, as the case may be, at a rate per
annum which is determined by increasing each of the Applicable Margins set forth
in clauses (a), (b) and (c) of Section 3.4 by 2% per annum for Loans so matured
   -----------  ---     ---    -----------                                     
and, to the extent permitted by applicable law, at a rate per annum equal to the
Base Rate plus 2% for such other monetary Liabilities.

     SECTION 3.6    Payment Dates.  Interest accrued on the Notes prior to
                    -------------                                         
Maturity (as aforesaid) shall be payable, without duplication:

          (a) on that portion of the outstanding principal amount of each Note
     maintained as a Base Rate Loan, on each Monthly Payment Date, commencing
     with the first such Monthly Payment Date following the date of such Notes;

          (b) on that portion of the outstanding principal amount of each Note
     maintained as one or more Fixed Rate Loans, on the last day of each
     applicable Interest Period; and

          (c) on that portion of the outstanding principal amount of each Note
     converted into a Base Rate Loan or a Fixed Rate Loan, as the case may be,
     on a day when interest would not otherwise have been payable pursuant to
     clause (a) or (b), on the date of such conversion.
     ----------    ---                                 

Interest on the Notes shall be payable at Maturity (as aforesaid) and,
thereafter, on demand.  The Bank shall give prompt notice to the Borrower of
each computation of accrued interest before the due date thereof.

     SECTION 3.7    Payments, Computations, etc.  Unless otherwise expressly
                    ----------------------------                            
provided in this Agreement, all payments by the Borrower pursuant to this
Agreement, the Notes, or any other Loan Document, whether in respect of
principal or interest, shall be made by the Borrower to the Bank without set-
off, deduction, or counterclaim, not later than 2:00 pm, New York time, on the
date due, in same day or immediately available funds, to such account as the
Bank shall specify from time to time by notice to the Borrower.  Funds received
after that time shall be deemed to have been received by the Bank on the next
following Business Day.  All interest and fees shall be computed on the basis of
the actual number of days (including the first day but excluding the last day)
occurring during the period for which fee is payable over a year comprised of
360 days.  Whenever any payment to be

                                      19
<PAGE>
 
made shall otherwise be due on a day which is not a Business Day, such payment
shall (except as otherwise required by clause (d) of the definition of the term
                                       ----------                              
"Interest Period" with respect to payments then due of principal of or interest
 ---------------                                                               
on any Notes being maintained as LIBO Rate Loans) be made on the next succeeding
Business Day and such extension of time shall be included in computing interest,
if any, in connection with such payment.

     SECTION 3.8    Setoff.  In addition to and not in limitation of any rights
                    ------                                                     
of the Bank or other holder of any Note under applicable law, the Bank shall,
upon the occurrence of any Default described in Section 8.1.4 or upon the
                                                -------------            
occurrence of any other Event of Default, have the right to set off, appropriate
and apply to the payment of the Liabilities owing to it any and all balances,
credits, deposits, accounts, or moneys of the Borrower then maintained with the
Bank and (as security for such Liabilities) the Borrower hereby grants to the
Bank a continuing security interest in any and all balances, credits, deposits,
accounts or moneys of the Borrower then or thereafter maintained with such Bank.
The Bank agrees promptly to notify the Borrower after any such setoff and
application made by the Bank; provided, however, that the failure to give such
                              --------  -------                               
notice shall not affect the validity of such setoff and application.  The rights
of the Bank under this Section are in addition to other rights and remedies
(including other rights of setoff under applicable law or otherwise) which the
Bank may have.

     SECTION 3.9    Taxes.  (a) All payments by the Borrower of principal of,
                    -----                                                    
and interest on, the Loans and all other amounts payable hereunder to any
recipient (including any Purchasing Bank) shall be made free and clear of and
without deduction or withholding for any present or future income, stamp, or
other taxes, fees, duties or other charges of any nature whatsoever imposed by
any taxing authority, other than taxes imposed on or measured by such
recipient's net income or receipts (such nonexcluded items being hereinafter
referred to as "Taxes"), except to the extent that such deduction or withholding
                -----                                                           
is required pursuant to any applicable law, rule, or regulation.  In the event
that any deduction or withholding from any payment to be made by the Borrower
hereunder is required in respect of any Taxes pursuant to any applicable law,
rule, or regulation, then the Borrower will:

          (i)   pay to the relevant authority the full amount required to be so
     withheld or deducted;

          (ii)  promptly forward to the Bank an official receipt or other
     documentation satisfactory to the Bank evidencing such payment to such
     authority; and

          (iii) (except to the extent that such deduction or withholding
     results from the breach, by a recipient of a payment, of its Exemption
     Agreement, or would not be required if such recipient's Exemption
     Representation were true) pay to the Bank or holder of a Note such
     additional amount or amounts as is necessary to ensure that the net amount
     actually received by the Bank or such holder, after giving effect to any
     credit against Taxes received by the Bank or such holder as a result of
     such deduction or withholding, will equal the full amount the Bank or such
     holder would have

                                      20
<PAGE>
 
     received had no such deduction or withholding been required.  The Bank and
     holder shall determine such additional amount or amounts payable to it
     (which determination shall, in the absence of demonstrable error, be
     conclusive and binding on the Borrower).

Moreover, if any Taxes are directly imposed on the Bank, as a result of any
change in law or any applicable double taxation treaty of the United States, the
jurisdiction of the Bank's incorporation or the jurisdiction in which the Bank's
Domestic Office or LIBOR Office is located, with respect to any payment received
by the Bank hereunder, the Bank may pay such Taxes and the Borrower will
promptly pay such additional amounts (including any penalties, interest or out-
of-pocket expenses) as are necessary in order that the net amount received by
the Bank after the payment of such Taxes (including any Taxes on such additional
amount) shall equal the amount such Person would have received had such Taxes
not been imposed (except to the extent that such Taxes result from the breach,
by such payee, of its Exemption Agreement, or would not be required if such
payee's Exemption Representation were true).

     (b) If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Bank the required receipts or other
required documentary evidence, the Borrower shall indemnify the Bank for any
incremental Taxes, interest or penalties that may become payable by the Bank as
a result of any such failure.

     (c) The Bank and each subsequent holder of any Note that is a Non-United
States Person agrees (the Bank's "Exemption Agreement") (to the extent it is
                                  -------------------                       
permitted to do so under the laws and any applicable double taxation treaties of
the United States, the jurisdiction of the Bank's incorporation, and the
jurisdictions in which the Bank's Domestic Office and the Bank's LIBOR office
are located) to execute and deliver to the Borrower prior to the first scheduled
payment date in each Fiscal Year, a United States Internal Revenue Service Form
1001 or Form 4224 (or any successor form), appropriately completed and claiming
complete (or, in the case it becomes appropriate due to any change in law or
such applicable double taxation treaties, partial) exemption from withholding
and deduction of United States Federal Taxes.

     (d) The Bank and each Purchasing Bank hereby represents and warrants (such
Bank's "Exemption Representation") to the Borrower that on the date hereof (or,
        ------------------------                                               
in the case of a Purchasing Bank, on the date on which such Purchasing Bank
becomes a Bank hereunder) (i) its Domestic Office and its LIBOR Office are
entitled to receive payments of principal of, and interest on, Loans made
hereunder without deduction or withholding for or on account of any Taxes
imposed by the United States or any political subdivision thereof, (ii) it is
permitted to take the actions described in clause (c) above (with respect to
                                           ----------                       
complete exemption from withholding and deduction of United States Federal
Taxes) under the laws and any applicable double taxation treaties of the
jurisdictions specified in such clause (c) and (iii) any payment received by
                                ----------                                  
such Bank hereunder is not subject to any Taxes, whether or not such Taxes are
required to be deducted or withheld by the Borrower.

                                      21
<PAGE>
 
     (e)   The Bank agrees to use reasonable efforts to change its Domestic
Office or LIBOR Office or prepare, execute and file any additional forms or
other documents which may be necessary or advisable to avoid or to minimize any
amounts otherwise payable under this Section 3.9, in each case solely if such
                                     -----------
change or such preparation, execution and filing can be made or done in a manner
so that the Bank, in its reasonable determination, suffers no legal, economic or
regulatory disadvantage.

     (f)   In the event that the Borrower becomes required to pay an additional
amount pursuant to this Section 3.10 to the Bank, then the Borrower shall have
                        ------------                                          
the right to seek a substitute bank or banks to promptly replace the Bank under
this Agreement in accordance with the provisions of Section 10.11(b).
                                                    ---------------- 

     (g)   The parties agree to cooperate with each other in connection with any
Taxes matters pertaining to this Agreement and the Bank shall promptly notify
the Borrower of any Taxes imposed on it with respect to any payment received by
the Bank hereunder, stating the reasons therefor and the amount, if any, payable
by the Borrower hereunder in respect of such Taxes.

                             OPTIONS FOR THE LOANS

     SECTION 4.1    Elections.  The Loans comprising any Borrowing may be made
                    ---------

this Section, as a loan (a "Fixed Rate Loan") having for each particular
                            ---------------                             
Interest Period a fixed rate of interest determined by reference to either the
LIBO Rate (Reserve Adjusted) (a "LIBO Rate Loan") or, the CD Rate (Reserve
                                 --------------                           
Adjusted) (a "CD Rate Loan"), as specified in the Loan Request for such Loan.
              ------------                                                    
The Borrower may from time to time by delivering to the Bank a
Continuation/Conversion Notice request, on not less than one (or not less than
three if a Loan is to be continued as, or converted into, a LIBO Rate Loan) nor
more than five Business Days' notice:

           (a)  that all, or any portion in a minimum amount of $500,000 or an
     integral multiple of $100,000 in excess thereof, of the outstanding
     principal amount of any Borrowing be converted from Base Rate Loans into
     Fixed Rate Loans of either type or, subject to Section 4.5, from either
                                                    -----------             
     type of Fixed Rate Loans into Base Rate Loans or Fixed Rate Loans of the
     other type; and

           (b)   on the expiration of the Interest Period applicable to any
     Fixed Rate Loans, that all, or any portion in a minimum amount of $500,000
     or an integral multiple of $100,000 in excess thereof, of the outstanding
     principal amount of such Fixed Rate Loans be continued as Fixed Rate Loans
     of such type or be converted into

                                      22
<PAGE>
 
     Base Rate Loans or Fixed Rate Loans of the other type (in the absence of
     the delivery of a Continuation/Conversion Notice pursuant to this clause,
     the Borrower will be deemed to have requested that such Fixed Rate Loans be
     converted into Base Rate Loans);

provided, however, that:

          (c)   no portion of the outstanding principal amount of any Loans may
     be continued as, or be converted into, Fixed Rate Loans if, after giving
     effect to such action, the Interest Period applicable thereto shall extend
     beyond the date of any prepayment required by Section 3.3, unless a
                                                   -----------
     sufficient principal amount of other Loans are being maintained as Base
     Rate Loans to permit such prepayment to be applied in full to such Base
     Rate Loans; and

          (d)   no portion of the outstanding principal amount of any Loans may
     be continued as, or be converted into, a Fixed Rate Loan when any Default
     has occurred and is continuing.

Each Continuation/Conversion Notice requesting that all, or any portion, of the
principal amount of the Loans be continued as, or be converted into, Fixed Rate
Loans shall specify the duration of the Interest Period commencing upon such
continuation or conversion.

     The Bank may, if it so elects, fulfill its commitment to make or continue
any portion of the principal amount of a Loan as, or to convert any portion of
the principal amount of a Loan into, one or more Fixed Rate Loans by causing a
foreign branch or Affiliate of the Bank to make any such Fixed Rate Loan;
provided, however, that in such event such Fixed Rate Loan shall be deemed to
- --------  -------                                                            
have been made by the Bank, and the obligation of the Borrower to repay such
Fixed Rate Loan shall nevertheless be to the Bank and shall be deemed to be held
by it, to the extent of such Fixed Rate Loan, for the account of such foreign
branch or Affiliate; and provided, further, that the making of such Fixed Rate
                         --------  -------                                    
Loans by a foreign branch or Affiliate of the Bank does not result in any
additional Taxes assessable against the Bank in connection with any payments
made by the Borrower hereunder.

     Whenever the Bank makes any notations pursuant to Section 3.2 on the grid
                                                       -----------            
attached to the Note (or on the continuation of such grid) and whenever the Bank
converts a Loan into a Base Rate Loan or a Fixed Rate Loan, the Bank will make
further notations on the grid attached to such Note (or on such continuation)
reflecting the portions of the outstanding principal amounts thereof being
maintained as a Base Rate Loan and Fixed Rate Loans.  Failure to record any such
amounts on the grid shall not limit or otherwise affect the obligations of the
Borrower to make payments of principal and interest on each Note when due.

     The Borrower understands that, if it elects that any portion of the
principal amount of a Borrowing be made, continued as, or converted into, a
Fixed Rate Loan, the Bank may

(while being entitled to fund all or any portion of such Fixed Rate Loan as it
may see fit) wish to be able to fund such Fixed Rate Loan by issuing Dollar
certificates of deposit in New York City or purchasing Dollar deposits in its
LIBOR Office's interbank eurodollar market.  Accordingly, in connection with any
determination to be made for purposes of Section 4.2, 4.3, 4.4 or 4.5, it shall
                                         -----------  ---  ---    ---          
be conclusively presumed that the Bank has elected to fund all Fixed Rate Loans
by issuing Dollar certificates of deposit in New York City, in the case of CD
Rate Loans, or purchasing Dollar deposits in such interbank eurodollar market,
in the case of LIBO Rate Loans.

     SECTION 4.2    Fixed Rate Lending Unlawful.  If as the result of any
                    ---------------------------                          
Regulatory Change the Bank shall determine (which determination shall, in the
absence of demonstrable error, be conclusive and binding on the Borrower) that
it is unlawful for the Bank to make, continue or maintain a Loan as, or to
convert a Loan into, one or more Fixed Rate Loans of a certain type, the
obligation of the Bank under Section 4.1 to make, continue or maintain any
                             -----------                                  
portion of the principal amount of a Loan as, or to convert such Loan into, one
or more Fixed Rate Loans of such type shall, upon such determination (and
telephonic notice thereof confirmed in writing to the Borrower), forthwith
terminate, and any portion of the principal amount of a Loan then maintained as
one or more Fixed Rate Loans of such type by the Bank shall automatically
convert into a Base Rate Loan.  If circumstances subsequently change so that the
Bank shall determine that it is no longer so affected, the obligation of the
Bank under Section 4.1 to make or continue Loans as, or to convert Loans into,
           -----------                                                        
Fixed Rate Loans shall, upon such determination and telephonic notice thereof
confirmed in writing to the Borrower), forthwith be reinstated.

     SECTION 4.3    Deposits Unavailable.  If prior to the date on which all or
                    --------------------                                       
any portion of the principal amount of any Loan is to be made, continued as, or
converted into, a Fixed Rate Loan, the Bank shall determine for any reason
whatsoever (which determination shall, in the absence of demonstrable error, be
conclusive and binding on the Borrower) that dollar deposits in the relevant
amount and for the relevant Interest Period are not available to the Bank in its
relevant market, the Bank shall promptly give telephonic notice of such
determination confirmed in writing to the Borrower, and the obligation under
Section 4.1 of the Bank to make, continue any portion of the principal amount of
- -----------                                                                     
a Loan as, or to convert a Loan into, one or more Fixed Rate Loans of such type
shall, upon such notification, forthwith terminate; and the portion of all Loans
then maintained as Fixed Rate Loans of such type by the Bank shall on the
expiration of the Interest Period applicable thereto automatically convert into
Base Rate Loans.

If circumstances subsequently change so that the Bank shall no longer be so
affected, the Bank shall promptly give telephonic notice thereof confirmed in
writing to the Borrower and the obligations of the Bank under Section 4.1 to
                                                              -----------   
make or continue Loans as, or convert Loans into, Fixed Rate Loans shall be
reinstated.

                    ---------------------------------------              
further agrees to reimburse the Bank for any increase in the cost to the Bank of
making, continuing,

maintaining or converting (or of its obligation to make, continue, maintain or
convert) any of its Loans hereunder (or any portion thereof) and for any
reduction in the amount of any sum receivable by the Bank hereunder in respect
of making, continuing, maintaining or converting (or of its obligation to make,
continue, maintain or convert) any of its Loans hereunder (or any portion
thereof) from time to time by reason of:

          (a)   to the extent not included in the calculation of the LIBO Rate
     (Reserve Adjusted), the adoption or compliance with any capital adequacy,
     reserve, special deposit, or similar requirement against assets of,

     or pursuant to any law, treaty, rule, regulation (including any F.R.S.
     Board regulation), or requirement in effect on the date hereof, or as the
     result of any Regulatory Change; or

          (b)   any Regulatory Change which shall subject the Bank to any tax
     (other than taxes on net income or receipts), levy, impost, charge, fee,
     duty, deduction, or withholding of any kind whatsoever or change the
     taxation of any Loan made or maintained as a Fixed Rate Loan and the
     interest thereon (other than any change which affects, and to the extent
     that it affects, the taxation of net income or receipts).

In any such event, the Bank shall promptly notify the Borrower thereof stating
the reasons therefor and the additional amount required fully to compensate the
Bank for such increased cost or reduced amount.  Such additional amounts shall
be payable on demand after receipt of such notice.  A statement as to any such
increased cost or reduced amount or any change therein (including calculations
thereof in reasonable detail) shall be submitted by the Bank to the Borrower and
shall, in the absence of demonstrable error, be conclusive and binding on the
Borrower.  In the event that the Borrower is required to pay an additional
amount pursuant to this Section 4.4 to the Bank, then the Borrower shall have
                        -----------

Agreement in accordance with the provisions of Section 10.11(b).

     SECTION 4.5    Funding Losses.  In the event the Bank shall incur any loss
                    --------------

     Loan on a date other than the scheduled last day of the Interest Period
     applicable thereto, whether pursuant to Section 3.3 or otherwise;

     Rate Loan in accordance with a Loan Request or the Continuation/Conversion

Bank for such loss or expense.  A certificate as to any such loss or expense
(including calculations thereof in reasonable detail) shall be submitted by the
Bank to the Borrower and shall, in the absence of demonstrable error, be
conclusive and binding on the Borrower.

     such Assigning Bank must retain at least $9,000,000 and (ii) any Purchasing
     Bank must be acceptable to the Borrower, whose consent shall not be
     unreasonably withheld, and the Bank's and the Borrower's decisions
     respecting the same shall be made promptly.  In the event of any
     assignment, the Assigning Bank shall give notice to the Borrower and shall
     deliver to the Borrower, for its acceptance and recording in its records,
     an Assignment and Acceptance, which shall include an Exemption
     Representation and, if such Purchasing Bank is a Non-United States Person,

                                                                     --------
     that the Borrower shall be entitled to continue to deal solely and directly
     with the Assigning Bank in connection with the interests so assigned to the
     Purchasing Bank until the Assignment and Acceptance shall have been
     delivered to the Borrower collectively by the Assigning Bank and the
     Purchasing Bank.  Upon the assignment of Credit Exposure provided for
     hereby, the Assigning Bank shall be relieved of its obligations hereunder
     to the extent of such assignment.  In the event of any assignment, the
     Borrower shall, at its sole cost and expense, prepare and deliver to the
     Assigning Bank and to the Purchasing Bank new Notes reflecting the effect
     of such assignment.

          (c) The Borrower authorizes the Bank to disclose to any Participant or
     Purchasing Bank (each, a "Transferee") and any prospective Transferee any
                               ----------

          (d) The Bank shall have the right to collaterally assign its rights
     hereunder or under any other Loan Document to any Federal Reserve Bank in
     accordance with applicable law.

Affiliates in which the Borrower or such Affiliate is not restricted hereby from
engaging with any other Person.

UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY
COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN), OR
ACTIONS OF THE BANK, OR THE BORROWER.  THIS PROVISION IS A MATERIAL INDUCEMENT
FOR THE BANK ENTERING INTO THIS AGREEMENT.

     SECTION 10.14  Consent to Jurisdiction and Service of Process.  Any
                    ----------------------------------------------      
judicial proceedings brought against the Borrower with respect to this Agreement
or any Note may be brought in any state or federal court of competent
jurisdiction in the State of New York and by the execution and delivery of this
Agreement the Borrower accepts the nonexclusive jurisdiction of the aforesaid
courts.  Service of process may be made by any means authorized by federal law
or the law of New York.  A copy of any such process so served shall be mailed by
registered mail to the Borrower at its address set forth below its signature
hereto or at such other address as may be designated by the Borrower in a notice
to the Bank.  Nothing herein shall limit the right of any Bank to bring

     commencing with the first such day following October 29, 1998 and on the

K.   SECTION 3.3 is amended in its entirety to read as follows:

          SECTION 3.3  Principal Payments and Prepayments.  The Borrower will
                       ----------------------------------                    
     repay the outstanding principal amount of the Notes on the Commitment
     Termination Date.  In addition, the Borrower:

          a.   may make a voluntary prepayment in part in an aggregate principal
     amount of not less than $500,000 and an integral multiple of $100,000 in
     excess thereof, or in full of the outstanding principal amount of the Notes
     from time to

     notice (or same day notice in the case of a Base Rate Loan) to the Bank;

          b.   shall, on each date when any reduction in the Total Commitment
     Amount shall become effective pursuant to Section 2.2, make a mandatory
                                               -----------                  
     prepayment of the Notes equal to the excess, if any, of the outstanding
     principal amount of all Loans over the Total Commitment Amount as so
     reduced; and

          c.   shall, on each date when the sum of the aggregate principal
     amount of all Loans outstanding plus the Commercial Paper Indebtedness
     exceeds the Total Commitment Amount, make a mandatory prepayment of the
     then aggregate outstanding principal amount of all Loans in an aggregate
     amount equal to such excess.

     Each prepayment of a Note made pursuant to this Section shall be without
     premium or penalty, except as may be required by Section 4.5.  All interest
                                                      -----------               
     accrued on the principal amount of Notes prepaid shall be paid on the date
     of such prepayment.  No prepayment of principal of the Notes pursuant to

     principal amount of the Notes from time to time unpaid prior to and at
     Maturity at a rate per annum:

               (a)  on that portion of the outstanding principal amount thereof
          maintained from time to time as a Base Rate Loan, equal to the sum of
          the Base Rate from time to time most recently announced plus the
          Applicable Margin per annum, and

               (b)  on that portion of the outstanding principal amount thereof
          maintained from time to time as one or more LIBO Rate Loans during

                       -------------------                                   
     portion of the principal amount of the Loans or after any other monetary
     Liabilities shall have become due, the Borrower shall pay interest (after
     as well as before judgment) on the principal amount of all types of Loans
     so matured or on such other monetary Liabilities, as the case may be, at a
     rate per annum which is determined by increasing each of the Applicable
     Margins set forth in clauses (a) and (b) of Section 3.4 by 2% per annum for
                          -----------     ---    -----------

     Liabilities.

N.   SECTION 3.6 is amended in its entirety to read as follows:

          SECTION 3.6  Payment Dates.  Interest accrued on the Notes prior to

          Note converted into a Base Rate Loan or a LIBO Rate Loan, as the case
          may be, on a day when interest would not otherwise have been payable
          pursuant to clause (a) or (b), on the date of such conversion.
                      ----------    ---

                 BASE RATE AND LIBO RATE OPTIONS FOR THE LOANS

     SECTION 4.1    Elections.  The Loans comprising any Borrowing may be made
                    ---------

Bank a Continuation/Conversion Notice request, on not less than one (or not less
than three if a Loan is to be continued as, or converted into, a LIBO Rate Loan)
nor more than five Business Days' notice:

               (a)  that all, or any portion in a minimum amount of $500,000 or
          an integral multiple of $100,000 in excess thereof, of the outstanding

                                              -----------                      
          into Base Rate Loans; and

               (b)  on the expiration of the Interest Period applicable to any
          LIBO Rate Loans, that all, or any portion in a minimum amount of
          $500,000 or an integral multiple of $100,000 in excess thereof, of the
          outstanding principal amount of such LIBO Rate Loans be converted into
          Base Rate Loans;

provided, however, that:

               (c)  no portion of the outstanding principal amount of any Loans
          may be continued as, or be converted into, LIBO Rate Loans if, after
          giving effect to such action, the Interest Period applicable thereto
          shall extend beyond the date of any prepayment required by Section
                                                                     -------
          3.3, unless a sufficient principal amount of other Loans are being
          ---
          maintained as Base Rate Loans to permit such prepayment to be applied
          in full to such Base Rate Loans; and

          may be continued as, or be converted into, a LIBO Rate Loan when any
          Default has occurred and is continuing.

Each Continuation/Conversion Notice requesting that all, or any portion, of the
principal amount of the Loans be continued as, or be converted into, LIBO Rate
Loans shall specify the duration of the Interest Period commencing upon such
continuation or conversion.

                                      -8-

     The Bank may, if it so elects, fulfill its commitment to make or continue
any portion of the principal amount of a Loan as, or to convert any portion of
the principal amount of a Loan into, one or more LIBO Rate Loans by causing a
foreign branch or Affiliate of the Bank to make any such LIBO Rate Loan;
provided, however, that in such event such LIBO Rate Loan shall be deemed to
- -----------------                                                           
have been made by the Bank, and the obligation of the Borrower to repay such
LIBO Rate Loan shall nevertheless be to the Bank and shall be deemed to be held
by it, to the extent of such LIBO Rate Loan, for the account of such foreign
branch or Affiliate; and provided, further, that the making of such LIBO Rate
                         -----------------                                   
Loans by a foreign branch or Affiliate of the Bank does not result in any
additional Taxes assessable against the Bank in connection with any payments
made by the Borrower hereunder.

     Whenever the Bank makes any notations pursuant to Section 3.2 on the grid
                                                       -----------            
attached to the Note (or on the continuation of such grid) and whenever the Bank
converts a Loan into a Base Rate Loan or a LIBO Rate Loan, the Bank will make
further notations on the grid attached to such Note (or on such continuation)
reflecting the portions of the outstanding principal amounts thereof being
maintained as a Base Rate Loan and LIBO Rate Loans.  Failure to record any such
amounts on the grid shall not limit or otherwise affect the obligations of the
Borrower to make payments of principal and interest on each Note when due.

     The Borrower understands that, if it elects that any portion of the
principal amount of a Borrowing be made, continued as, or converted into, a LIBO
Rate Loan, the Bank may (while being entitled to fund all or any portion of such
LIBO Rate Loan as it may see fit) wish to be able to fund such LIBO Rate Loan by
purchasing Dollar deposits in its LIBOR Office's interbank eurodollar market.
Accordingly, in connection with any determination to be made for purposes of
Section 4.2, 4.3, 4.4 or 4.5, it shall be conclusively presumed that the Bank
- -----------  ---  ---    ---                                                 
has elected to fund all LIBO Rate Loans by purchasing Dollar deposits in such
interbank eurodollar market.

     SECTION 4.2    LIBO Rate Lending Unlawful.  If as the result of any
                    --------------------------                          
Regulatory Change the Bank shall determine (which determination shall, in the
absence of demonstrable error, be conclusive and binding on the Borrower) that
it is unlawful for the Bank to make, continue or maintain a Loan as, or to
convert a Loan into, one or more LIBO Rate Loans, the obligation of the Bank
under Section 4.1 to make, continue or maintain any portion of the principal
      -----------                                                           
amount of a Loan as, or to convert such Loan into, one or more LIBO Rate Loans
shall, upon such determination (and telephonic notice thereof confirmed in
writing to the Borrower), forthwith terminate, and any portion of the principal
amount of a Loan then maintained as one or more LIBO Rate Loans by the Bank
shall automatically convert into a Base Rate Loan.  If circumstances
subsequently change so that the Bank shall determine that it is no

                                      -9-

longer so affected, the obligation of the Bank under Section 4.1 to make or
                                                     -----------           
continue Loans as, or to convert Loans into, LIBO Rate Loans shall, upon such
determination (and telephonic notice thereof confirmed in writing to the
Borrower), forthwith be reinstated.

     SECTION 4.3    Deposits Unavailable.  If prior to the date on which all or
                    --------------------                                       
any portion of the principal amount of any Loan is to be made, continued as, or
converted into, a LIBO Rate Loan, the Bank shall determine for any reason
whatsoever (which determination shall, in the absence of demonstrable error, be
conclusive and binding on the Borrower) that dollar deposits in the relevant
amount and for the relevant Interest Period are not available to the Bank in its
relevant market, the Bank shall promptly give telephonic notice of such
determination confirmed in writing to the Borrower, and the obligation under
Section 4.1 of the Bank to make, continue any portion of the principal amount of
- -----------                                                                     
a Loan as, or to convert a Loan into, one or more LIBO Rate Loans shall, upon
such notification, forthwith terminate; and the portion of all Loans then
maintained as LIBO Rate Loans by the Bank shall on the expiration of the
Interest Period applicable thereto automatically convert into Base Rate Loans.
If circumstances subsequently change so that the Bank shall no longer be so
affected, the Bank shall promptly give telephonic notice thereof confirmed in
writing to the Borrower and the obligations of the Bank under Section 4.1 to
                                                              -----------   
make or continue Loans as, or convert Loans into, LIBO Rate Loans shall be
reinstated.

     SECTION 4.4    Capital Adequacy; Increased Costs, etc.  The Borrower
                    --------------------------------------               
further agrees to reimburse the Bank for any increase in the cost to the Bank of
making, continuing, maintaining or converting (or of its obligation to make,
continue, maintain or convert) any of its Loans hereunder (or any portion
thereof) and for any reduction in the amount of any sum receivable by the Bank
hereunder in respect of making, continuing, maintaining or converting (or of its
obligation to make, continue, maintain or convert) any of its Loans hereunder
(or any portion thereof) from time to time by reason of:

               (a)  to the extent not included in the calculation of the LIBO
          Rate (Reserve Adjusted), the adoption or compliance with any capital
          adequacy, reserve, special deposit, or similar requirement against
          assets of, deposits with or for the account of, or credit extended by,
          the Bank, under or pursuant to any law, treaty, rule, regulation
          (including any F.R.S. Board regulation), or requirement in effect on
          the date hereof, or as the result of any Regulatory Change; or

               (b)  any Regulatory Change which shall subject the Bank to any
          tax (other than taxes on net income or receipts), levy, impost,
          charge, fee, duty, deduction, or withholding of any kind whatsoever or
          change the taxation

                                      -10-

          of any Loan made or maintained as a LIBO Rate Loan and the interest
          thereon (other than any change which affects, and to the extent that
          it affects, the taxation of net income or receipts).

In any such event, the Bank shall promptly notify the Borrower thereof stating
the reasons therefor and the additional amount required fully to compensate the
Bank for such increased cost or reduced amount.  Such additional amounts shall
be payable on demand after receipt of such notice.  A statement as to any such
increased cost or reduced amount or any change therein (including calculations
thereof in reasonable detail) shall be submitted by the Bank to the Borrower and
shall, in the absence of demonstrable error, be conclusive and binding on the
Borrower.  In the event that the Borrower is required to pay an additional
amount pursuant to this Section 4.4 to the Bank, then the Borrower shall have
                        -----------                                          
the right to seek a substitute bank or banks to replace the Bank under this
Agreement in accordance with the provisions of Section 10.11(b).
                                               ---------------- 

     SECTION 4.5    Funding Losses.  In the event the Bank shall incur any loss
                    --------------                                             
or expense (including any loss or expense incurred by reason of the liquidation,
or reemployment of deposits or other funds acquired by the Bank to make,
continue or maintain any portion of the principal amount of any Loan as, or to
convert any portion of the principal amount of any Loan into, a LIBO Rate Loan)
as a result of:

               (a)  payment or prepayment of the principal amount of any LIBO
          Rate Loan on a date other than the scheduled last day of the Interest
          Period applicable thereto, whether pursuant to Section 3.3 or
                                                         -----------   
          otherwise;

               (b)  any conversion of all or any portion of the outstanding
          principal amount of any LIBO Rate Loan to a Base Rate Loan pursuant to
          Section 4.1 prior to the expiration of the Interest Period then
          -----------                                                    
          applicable thereto (but excluding in each case any loss or expense
          resulting therefrom to the extent the Bank is reimbursed therefor by
          interest payable pursuant to clause (c) of Section 3.6); or
                                       ----------    ------------    

               (c)  a Loan not being made, continued as, or converted into, a
          LIBO Rate Loan in accordance with a Loan Request or the
          Continuation/Conversion Notice given therefor (other than as the
          result of a default by the Bank in complying with such Loan Request or
          such Continuation/Conversion Notice);

     then, upon the request of the Bank, the Borrower shall pay directly to the
     Bank such amount as will (in the reasonable determination of the Bank)
     reimburse the Bank for such loss or

                                      -11-

     expense.  A certificate as to any such loss or expense (including
     calculations thereof in reasonable detail) shall be submitted by the Bank
     to the Borrower and shall, in the absence of demonstrable error, be
     conclusive and binding on the Borrower.

P.   SECTION 6.18 is hereby added to the Loan Agreement, to read as
     follows:

          SECTION 6.18  Year 2000.  The Borrower has reviewed the areas within
                        ---------                                             
     its business and operations which could be adversely affected by, and has
     developed or is developing a program to address, on a timely basis, the
     "Year 2000 Problem" (that is, the risk that computer applications used by
     the Borrower may be unable to recognize and perform properly date sensitive
     functions involving certain dates prior to and any date on or after
     December 31, 1999), and has made related appropriate inquiry of material
     suppliers and vendors.  The Borrower believes that with modification and
     replacement of existing software and hardware, the Year 2000 Issue can be
     substantially mitigated.  However, if such modifications and replacements
     are not made, or are not completed on a timely basis, which the Borrower
     currently does not anticipate, the Year 2000 Issue could have a material
     impact on the operations of the Borrower.  The inability of a substantial
     number of third parties to complete their Year 2000 resolution process
     could materially impact the Borrower.

Q.   SECTION 6.19 is hereby added to the Loan Agreement, to read as follows:

          SECTION 6.19  Borrower's Solvency.  Both prior to and after giving
                        -------------------                                 
     effect to the Sixth Amendment to this Agreement dated October 29, 1998, and
     the increase in the Total Commitment effected thereby, the Borrower is and
     will be Solvent.  As used in this Section, "Solvent" means the Borrower is
     able to pay its debts as they become due in the usual course of business.

R.   SECTION 7.2.6 is amended in its entirety to read as follows:

          SECTION 7.2.6  Dividends.  Neither the Borrower nor either Guarantor
                         ---------                                            
     shall pay any dividends to its respective shareholders upon the occurrence,
     or during the continuance of, any Default.  No dividend shall be paid by
     Borrower or either Guarantor other than in accordance with all applicable

executing and delivering to the Bank a Commitment Termination Date Extension
Request at least thirty (30) but not more than forty-five (45) days prior to the

                                LOANS AND NOTES

     SECTION 3.1  Borrowing Procedure.  By giving notice to the Bank on or
                  -------------------                                     
before 12:00 noon, New York time, the Borrower may from time to time irrevocably
request, on not less than three (or same-day in the case of a Base Rate Loan)
nor more than five Business Days' notice, that a Borrowing be made by the Bank
in an aggregate amount equal to the lesser of (i) a minimum amount of $500,000
and an integral multiple of $100,000 in excess thereof, or (ii) the unused
amount of the Commitment then available pursuant to Section 2.1. Such notice may
                                                    -----------                 
be oral and shall be confirmed in writing on or before the first Business Day
following such request by delivering a Loan Request to the Bank.  Subject to the
terms and conditions of this Agreement, each Borrowing shall be made on the
Business Day specified in the Loan Request therefor.  On such Business Day and
subject to such terms and conditions, the Bank shall provide the Borrower with
funds, on or before 11:00 a.m., New York time (or 3:00 p.m., New York time, in
the case of a Base Rate Loan), in an amount equal to such Loan Request by
transferring same day or immediately available funds to such account as the
Borrower shall specify from time to time by notice to the Bank.

     SECTION 3.2  Note.  All Loans made by the Bank shall be evidenced by a Note
                  ----                                                          
payable to the order of the Bank in a maximum principal amount equal to the
Bank's original Total Commitment Amount.  The Borrower hereby irrevocably
authorizes the Bank to make (or cause to be made) appropriate notations on the
grid attached to the Bank's Note (or on a continuation of such grid attached to
any such Note and made a part thereof), which notations, if made, shall
evidence, inter alia, the date of, the outstanding principal of, and the
          ----------                                                    
interest rate (including any conversions thereof pursuant to Section 4.2) and
                                                             -----------     
Interest Period applicable to, the Loans evidenced thereby.  Any such notations
on any such grid (and on any such continuation) indicating the outstanding
principal amount of the Bank's Loans shall be rebuttable presumptive evidence of
the principal amount thereof owing and unpaid, but the failure to record any
such amount on such grid (or on such continuation) shall not limit or otherwise
affect the obligations of the Borrower hereunder or under such Note to make
payments of principal of or interest on such Loans when due.

     SECTION 3.3  Principal Payments and Prepayments.  The Borrower will repay
                  ----------------------------------

In addition, the Borrower:

            a.   may make a voluntary prepayment in part in an aggregate
     principal amount of not less than $500,000 and an integral multiple of
     $100,000 in excess thereof, or in full of the outstanding principal amount
     of the Note from time to time at any time, in each case upon at least three
     Business Days, prior notice (or same day notice in the case of a Base Rate
     Loan) to the Bank;

            b.   shall, on each date when any reduction in the Total Commitment
     Amount shall become effective pursuant to Section 2.2, make a mandatory
                                               -----------                  
     prepayment of the Note equal to the excess, if any, of the outstanding
     principal amount of all Loans over the Total Commitment Amount as so
     reduced; and

                                     -13-
<PAGE>
 
          c.   shall, on each date when the sum of the aggregate principal
amount of all Loans outstanding plus the Commercial Paper Indebtedness exceeds
the Total Commitment Amount, make a mandatory prepayment of the then aggregate
outstanding principal amount of all Loans in an aggregate amount equal to such
excess.

     Each prepayment of a Note made pursuant to this Section shall be without
     premium or penalty, except as may be required by Section 4.5.  All interest
                                                      -----------               
     accrued on the principal amount of a Note prepaid shall be paid on the date
     of such prepayment.  No prepayment of principal of the Note pursuant to
     clause (a) or (c) above prior to the Commitment Termination Date shall
     ----------    ---                                                     
     cause a reduction in the Total Commitment Amount.

          Each prepayment of the Note shall, except as the Borrower may
otherwise have notified the Bank, be applied, to the extent of such prepayment:

                 (a) first, to the principal amount thereof being maintained as
          a Base Rate Loan; and

                 (b) second, to the principal amount thereof being maintained as
          a LIBO Rate Loan.

     SECTION 3.4  Interest.  The Borrower agrees to pay interest on the
                  --------                                             
principal amount of the Note from time to time unpaid prior to and at Maturity
at a rate per annum:

                 (a) on that portion of the outstanding principal amount thereof
          maintained from time to time as a Base Rate Loan, equal to the sum of
          the Base Rate from time to time most recently announced plus the
          Applicable Margin per annum, and

                 (b) on that portion of the outstanding principal amount thereof
          maintained from time to time as one or more LIBO Rate Loans during
          each applicable Interest Period, equal to the sum of the LIBO Rate
          (Reserve Adjusted) for such Interest Period plus the Applicable margin
          per annum.

     SECTION 3.5  Post-Maturity Rates.  After the Maturity of all or any portion
                  -------------------                                           
of the principal amount of the Loans or after any other monetary Liabilities
shall have become due, the Borrower shall pay interest (after as well as before
judgment) on the principal amount of all types of Loans so matured or on such
other monetary Liabilities, as the case may be, at a rate per annum which is
determined by increasing each of the Applicable Margins set forth in clauses (a)
                                                                     -----------
and (b) of Section 3.4 by 2% per annum for Loans so matured and, to the extent
    ---    -----------                                                        
permitted by applicable law, at a rate per annum equal to the Base Rate plus 2%
for such other monetary Liabilities.

     SECTION 3.6  Payment Dates.  Interest accrued on the Note prior to Maturity
                  -------------                                                 
(as aforesaid) shall be payable, without duplication:

                 (a) on that portion of the outstanding principal amount of each
          Note maintained as a Base Rate Loan, on each Monthly Payment Date,
          commencing with the first such Monthly Payment Date following the date
          of such Notes;

                 (b) on that portion of the outstanding principal amount of each
          Note maintained as one or more LIBO Rate Loans, on the last day of
          each applicable Interest Period; and

                 (c) on that portion of the outstanding principal amount of each
          Note converted into a Base Rate Loan or a LIBO Rate Loan, as

                                     -14-
<PAGE>
 
          the case may be, on a day when interest would not otherwise have been
          payable pursuant to clause (a) or (b), on the date of such conversion.
                              ----------    ---                                 

     Interest on the Note shall be payable at Maturity (as aforesaid) and,
     thereafter, on demand.  The Bank shall give prompt notice to the Borrower
     of each computation of accrued interest before the due date thereof.

     SECTION 3.7  Payments, Computations, etc.  Unless otherwise expressly
                  ----------------------------                            
provided in this Agreement, all payments by the Borrower pursuant to this
Agreement, the Note, or any other Loan Document, whether in respect of principal
or interest, shall be made by the Borrower to the Bank without set-off,
deduction, or counterclaim, not later than 2:00 pm, New York time, on the date
due, in same day or immediately available funds, to such account as the Bank
shall specify from time to time by notice to the Borrower.  Funds received after
that time shall be deemed to have been received by the Bank on the next
following Business Day.  All interest and fees shall be computed on the basis of
the actual number of days (including the first day but excluding the last day)
occurring during the period for which fee is payable over a year comprised of
360 days.  Whenever any payment to be made shall otherwise be due on a day which
is not a Business Day, such payment shall (except as otherwise required by
clause (d) of the definition of the term "Interest Period" with respect to
- ----------                                ---------------                 
payments then due of principal of or interest on any Note being maintained as
LIBO Rate Loans) be made on the next succeeding Business Day and such extension
of time shall be included in computing interest, if any, in connection with such
payment.

     SECTION 3.8  Setoff.  In addition to and not in limitation of any rights of
                  ------                                                        
the Bank or other holder of any Note under applicable law, the Bank shall, upon
the occurrence of any Default described in Section 8.1.4 or upon the occurrence
                                           -------------                       
of any other Event of Default, have the right to set off, appropriate and apply
to the payment of the Liabilities owing to it any and all balances, credits,
deposits, accounts, or moneys of the Borrower then maintained with the Bank and
(as security for such Liabilities) the Borrower hereby grants to the Bank a
continuing security interest in any and all balances, credits, deposits,
accounts or moneys of the Borrower then or thereafter maintained with such Bank.
The Bank agrees promptly to notify the Borrower after any such setoff and
application made by the Bank; provided, however, that the failure to give such
                              --------  -------                               
notice shall not affect the validity of such setoff and application.  The rights
of the Bank under this Section are in addition to other rights and remedies
(including other rights of setoff under applicable law or otherwise) which the
Bank may have.

     SECTION 3.9  Taxes.  (a)  All payments by the Borrower of principal of, and
                  -----                                                         
interest on, the Loans and all other amounts payable hereunder to any recipient
(including any Purchasing Bank) shall be made free and clear of and without
deduction or withholding for any present or future income, stamp, or other
taxes, fees, duties or other charges of any nature whatsoever imposed by any
taxing authority, other than taxes imposed on or measured by such recipient's
net income or receipts (such non-excluded items being hereinafter referred to as
"Taxes"), except to the extent that such deduction or withholding is required
 -----                                                                       
pursuant to any applicable law, rule, or regulation.  In the event that any
deduction or withholding from any payment to be made by the Borrower hereunder
is required in respect of any Taxes pursuant to any applicable law, rule, or
regulation, then the Borrower will:

            (i) pay to the relevant authority the full amount required to be so
     withheld or deducted;

<PAGE>
 
            (ii)   promptly forward to the Bank an official receipt or other
     documentation satisfactory to the Bank evidencing such payment to such
     authority; and

            (iii)  (except to the extent that such deduction or withholding
     results from the breach, by a recipient of a payment, of its Exemption
     Agreement, or would not be required if such recipients Exemption
     Representation were true) pay to the Bank or holder of a Note such
     additional amount or amounts as is necessary to ensure that the net amount
     actually received by the Bank or such holder, after giving effect to any
     credit against Taxes received by the Bank or such holder as a result of
     such deduction or withholding, will equal the full amount the Bank or such
     holder would have received had no such deduction or withholding been
     required.  The Bank and holder shall determine such additional amount or
     amounts payable to it (which determination shall, in the absence of
     demonstrable error, be conclusive and binding on the Borrower).

Moreover, if any Taxes are directly imposed on the Bank, as a result of any
change in law or any applicable double taxation treaty of the United States, the
jurisdiction of the Bank's incorporation or the jurisdiction in which the Bank's
Domestic Office or LIBOR Office is located, with respect to any payment received
by the Bank hereunder, the Bank may pay such Taxes and the Borrower will
promptly pay such additional amounts (including any penalties, interest or out-
of-pocket expenses) as are necessary in order that the net amount received by
the Bank after the payment of such Taxes (including any Taxes on such additional
amount) shall equal the amount such Person would have received had such Taxes
not been imposed (except to the extent that such Taxes result from the breach,
by such payee, of its Exemption Agreement, or would not be required if such
payee's Exemption Representation were true).

     (b)    If the Borrower fails to pay any Taxes when due to the appropriate
taxing authority or fails to remit to the Bank the required receipts or other
required documentary evidence, the Borrower shall indemnify the Bank for any
incremental Taxes, interest or penalties that may become payable by the Bank as
a result of any such failure.

     (c)    The Bank and each subsequent holder of any Note that is a Non-United
States Person agrees (the Bank's "Exemption Agreement" (to the extent it is
                                  -------------------                      
permitted to do so under the laws and any applicable double taxation treaties of
the United States, the jurisdiction of the Bank's incorporation, and the
jurisdictions in which the Bank's Domestic Office and the Bank's LIBOR Office
are located) to execute and deliver to the Borrower prior to the first scheduled
payment date in each Fiscal Year, a United States Internal Revenue Service Form
1001 or Form 4224 (or any successor form), appropriately completed and claiming
complete (or, in the case it becomes appropriate due to any change in law or
such applicable double taxation treaties, partial) exemption from withholding
and deduction of United States Federal Taxes.

     (d)    The Bank and each Purchasing Bank hereby represents and warrants
(such Bank's "Exemption Representation" to the Borrower that on the date hereof
              ------------------------
(or, in the case of a Purchasing Bank, on the date on which such Purchasing Bank
becomes a Bank hereunder) (i) its Domestic Office and its LIBOR Office are
entitled to receive payments of principal of, and interest on, Loans made
hereunder without deduction or withholding for or on account of any Taxes
imposed by the United States or any political subdivision thereof, (ii) it is
permitted to take the actions described in clause (c) above (with respect to
                                           ----------
complete exemption from withholding and deduction of United States Federal
Taxes) under the laws and any applicable double taxation treaties of the
jurisdictions specified in such clause (c) and (iii) any payment received by
                                ----------
such Bank hereunder is not subject to any Taxes, whether or not such Taxes are
required to be deducted or withheld by the Borrower.

                                     -16-
<PAGE>
 
     (d)   The Bank agrees to use reasonable efforts to change its Domestic
Office or LIBOR Office or prepare, execute and file any additional forms or
other documents which may be necessary or advisable to avoid or to minimize any
amounts otherwise payable under this Section 3.9, in each case solely if such
                                     -----------    
change or such preparation, execution and filing can be made or done in a manner
so that the Bank, in its reasonable determination, suffers no legal, economic or
regulatory disadvantage.

     (e)   In the event that the Borrower becomes required to pay an additional
amount pursuant to this Section 3.10 to the Bank, then the Borrower shall have
                        ------------                                          
the right to seek a substitute bank or banks to promptly replace the Bank under
this Agreement in .accordance with the provisions of Section 10.11(b).
                                                     ---------------- 

     (g)   The parties agree to cooperate with each other in connection with any
Taxes matters pertaining to this Agreement and the Bank shall promptly notify
the Borrower of any Taxes imposed on it with respect to any payment received by
the Bank hereunder, stating the reasons therefor and the amount, if any, payable
by the Borrower hereunder in respect of such Taxes.

Bank a Continuation/ Conversion Notice request, on not less than one (or not
less than three if a Loan is to be continued as, or converted into, a LIBO Rate
Loan) nor more than five Business Days, notice:

           (a)   that all, or any portion in a minimum amount of $500,000 or an
     integral multiple of $100,000 in excess thereof, of the outstanding
     principal amount of any Borrowing be converted from Base Rate Loans into
     LIBO Rate Loans or, subject to Section 4.5, from LIBO Rate Loans into Base

     principal amount of such LIBO Rate Loans be converted into Base Rate Loans;

     provided, however, that:

           (c)   no portion of the outstanding principal amount of any Loans may
     be continued as, or be converted into, LIBO Rate Loans if, after giving
     effect to such action, the Interest Period applicable thereto shall extend
     beyond the date of any prepayment required by Section 3.3, unless a
                                                   -----------
     sufficient principal amount of other Loans are being maintained as Base
     Rate Loans to permit such prepayment to be applied in full to such Base
     Rate Loans; and

           (d)   no portion of the outstanding principal amount of any Loans may
     be continued as, or be converted into, a LIBO Rate Loan when any Default
     has occurred and is continuing.

     Each Continuation/Conversion Notice requesting that all, or any portion, of
     the principal amount of the Loans be continued as, or be converted into,
     LIBO Rate Loans shall specify the duration of the Interest Period
     commencing upon such continuation or conversion.

          The Bank may, if it so elects, fulfill its commitment to make or
     continue any portion of the principal amount of a Loan as, or to convert
     any portion of the principal amount of a Loan into, one or more LIBO Rate
     Loans by causing a foreign branch or Affiliate of the Bank to make any such
     LIBO Rate Loan; provided, however, that in such event such LIBO Rate Loan
                     --------  -------                                        
     shall be deemed to have been made by the Bank, and the obligation of the
     Borrower to repay such LIBO Rate Loan shall nevertheless be to the Bank and
     shall be deemed to be held by it, to the extent of such LIBO Rate Loan, for
     the account of such foreign branch or Affiliate; and provided further that
                                                          -------- -------     
     the making of such LIBO Rate Loans by a foreign branch or Affiliate of the
     Bank does not result in any additional Taxes assessable against the Bank in
     connection with any payments made by the Borrower hereunder-


          Whenever the Bank makes any notations pursuant to Section 3.2 on the
                                                            -----------       
     grid attached to the Note (or on the continuation of such grid) and
     whenever the Bank converts a Loan into a Base Rate Loan or a LIBO Rate
     Loan, the Bank will make further notations on the grid attached to such
     Note (or on such continuation) reflecting the portions of the outstanding
     principal amounts thereof being maintained as a Base Rate Loan and LIBO
     Rate Loans.  Failure to record any such amounts on the grid shall not limit
     or otherwise affect the obligations of the Borrower to make payments of
     principal and interest on each Note when due.

          The Borrower understands that, if it elects that any portion of the
     principal amount of a Borrowing be made, continued as, or converted into, a
     LIBO Rate Loan, the Bank may (while being entitled to fund all or any
     portion of such LIBO Rate Loan as it may see fit) wish to be able to fund
     such LIBO Rate Loan by purchasing Dollar deposits in its LIBOR Office's
     interbank eurodollar market.  Accordingly, in connection with any
     determination to be made for purposes of Section 4.2, 4.3, 4.4 or 4.5, it

     shall be conclusively presumed that the Bank has elected to fund all LIBO
     Rate Loans by purchasing Dollar deposits in such interbank eurodollar
     market.

Regulatory Change the Bank shall determine (which determination shall, in the
absence of demonstrable error, be conclusive and binding on the Borrower) that
it is unlawful for the Bank to make, continue or maintain a Loan as, or to
convert a Loan into, one or more LIBO Rate Loans, the obligation of the Bank
under Section 4.1 to make, continue or maintain any portion of the principal
      -----------                                                           
amount of a Loan as, or to convert such Loan into, one or more LIBO Rate Loans
shall, upon such determination (and telephonic notice thereof confirmed in
writing to the Borrower), forthwith terminate, and any portion of the principal
amount of a Loan then maintained as one or more LIBO Rate Loans by the Bank
shall automatically convert into a Base Rate Loan.  If circumstances
subsequently change so that the Bank shall determine that it is no longer so
affected, the obligation of the Bank under Section 4.1 to make or continue Loans
                                           -----------

be conclusive and binding on the Borrower) that dollar deposits in the relevant
amount and for the relevant Interest Period are not available to the Bank in its
relevant market, the Bank shall promptly give telephonic notice of such
determination confirmed in writing to the Borrower, and the obligation under
Section 4.1 of the Bank to make, continue any portion of the principal amount of

a Loan as, or to convert a Loan into, one or more LIBO Rate Loans shall, upon
such notification, forthwith terminate; and the portion of all Loans then
maintained as LIBO Rate Loans by the Bank shall on the expiration of the
Interest Period applicable thereto automatically convert into Base Rate Loans.
If circumstances subsequently change so that the Bank shall no longer be so
affected, the Bank shall promptly give telephonic notice thereof confirmed in
writing to the Borrower and the obligations of the Bank under Section 4.1 to

                  ---------------------------------------                      
agrees to reimburse the Bank for any increase in the cost to the Bank of making,
continuing, maintaining or converting (or of its obligation to make, continue,
maintain or convert) any of its Loans hereunder (or any portion thereof) and for
any reduction in the amount of any sum receivable by the Bank hereunder in
respect of making, continuing, maintaining or converting (or of its obligation
to make, continue, maintain or convert) any of its Loans hereunder (or any
portion thereof) from time to time by reason of:

            (a)   to the extent not included in the calculation of the LIBO Rate
     (Reserve Adjusted), the adoption or compliance with any capital adequacy,
     reserve, special deposit, or similar requirement against assets of,

     or pursuant to any law, treaty, rule, regulation (including any F.R.S.
     Board regulation), or requirement in effect on the date hereof, or as the
     result of any Regulatory Change; or

            (b)   any Regulatory Change which shall subject the Bank to any tax

     duty, deduction, or withholding of any kind whatsoever or change the
     taxation of any Loan made or maintained as a LIBO Rate Loan and the
     interest thereon (other than any change which affects, and to the extent
     that it affects, the taxation of net income or receipts).

     In any such event, the Bank shall promptly notify the Borrower thereof
     stating the reasons therefor and the additional amount required fully to
     compensate the Bank for such increased cost or reduced amount.  Such
     additional amounts shall be payable on demand after receipt of such notice.
     A statement as to any such increased cost or reduced amount or any change
     therein (including calculations thereof in reasonable detail) shall be
     submitted by the Bank to the Borrower and shall, in the absence of
     demonstrable error, be conclusive and binding on the Borrower.  In the
     event that the Borrower is required to pay an additional amount pursuant to
     this Section 4.4 to the Bank, then the Borrower shall have the right to
          -----------

reemployment of deposits or other funds acquired by the Bank to make, continue
or maintain any portion of the principal amount of any Loan as, or to convert
any portion of the principal amount of any Loan into, a LIBO Rate Loan) as a

     Section 4.1 prior to the expiration of the Interest Period then applicable
     thereto (but excluding in each case any loss or expense resulting therefrom

                  ------------

     SECTION 6.11  Pension and Welfare Plans.  During the twelve-consecutive-
                   -------------------------

hereunder, (a) no steps have been taken to terminate any Pension Plan the assets

defined in section 4001(a)(16) of ERISA) for which the Borrower, either
Guarantor or any Subsidiary could be held liable, and (b) no contribution
failure has occurred with respect to any Pension Plan sufficient to give rise to

     SECTION 6.16  Accuracy of Information.  All factual information heretofore
                   -----------------------                                     
or contemporaneously furnished by the Borrower to the Bank in connection with
execution and delivery of this Agreement and the various transactions
contemplated hereby, as supplemented from time to time and when taken as a
whole, to the best of the Borrower's knowledge, has been, and all other such
factual information hereafter furnished by the Borrower, either Guarantor or any
Subsidiary, to the Bank, as supplemented from time to time

     Effect, or (ii) on the National Priorities List pursuant to CERCLA;

          (f) there are no underground storage tanks, active or abandoned,

                                     -25-
<PAGE>
 
     Significant Subsidiary that, singly or in the aggregate, have, or could
     reasonably be expected to have, a Materially Adverse Effect;

          (g) none of either Guarantor, the Borrower or any Significant
     Subsidiary has directly transported or directly arranged for the

     may lead to material claims against such Guarantor, the Borrower or such
     Significant Subsidiary for any remedial work, damage to natural resources

          (i) no conditions exist at, on or under any property now or previously

     a Materially Adverse Effect; and

          (j) none of either Guarantor, the Borrower or any Subsidiary owns or
     leases any "industrial establishment" (as such term is defined in the New
     Jersey Environmental Cleanup Responsibility Act, N.J.S.A. 13:1K-6, et seq.)
                                                                        -- ---

     SECTION 6.18  Year 2000.  The Borrower has reviewed the areas within its
                   ---------                                                 
business and operations which could be adversely affected by, and has developed
or is developing a program to address, on a timely basis, the "Year 2000
Problem" (that is, the risk that computer applications used by the Borrower may
be unable to recognize and perform properly date-sensitive functions involving
certain dates prior to and any date on or after December 31, 1999), and has made
related appropriate inquiry of material suppliers and vendors.  The Borrower
believes that with modification and replacement of existing software and
hardware, the Year 2000 Issue can be substantially mitigated.  However, if such
modifications and replacements are not made, or are not completed on a timely
basis, which the Borrower currently does not anticipate, the Year 2000 Issue
could have a material impact on the operations of the Borrower.  The inability
of a substantial number of third parties to complete their Year 2000 resolution
process could materially impact the Borrower.

     SECTION 6.19  Borrower's Solvency.  As of the date of this Agreement, the
                   -------------------                                        
Borrower is and will be Solvent.  As used in this Section, "Solvent" means the
Borrower is able to pay its debts as they become due in the usual course of
business.

     to an Affiliate of such Assigning Bank or another Senior Revolving Lender,
     it assigns its Credit Exposure in an amount not less than $9,000,000 and,
     unless such assignment covers all of such Assigning Bank's Credit Exposure,
     such Assigning Bank must retain at least $9,000,000 and (ii) any Purchasing
     Bank must be acceptable to the Borrower, whose consent shall not be
     unreasonably withheld, and the Bank's and the Borrower's decisions
     respecting the same shall be made promptly.  In the event of any
     assignment, the Assigning Bank shall give notice to the Borrower and shall

     with the Assigning Bank in connection with the interests so assigned to the
     Purchasing Bank until the Assignment and Acceptance shall have been

     Purchasing Bank.  Upon the assignment of Credit Exposure provided for
     hereby, the Assigning Bank shall be relieved of its obligations hereunder
     to the extent of such assignment.  In the event of any assignment, the
     Borrower shall, at its sole cost and expense, prepare and deliver to the
     Assigning Bank and to the Purchasing Bank new Notes reflecting the effect
     of such assignment.

          (c)  The Borrower authorizes the Bank to disclose to any Participant
     or Purchasing Bank (each, a "Transferee") and any prospective Transferee
                                  ----------
     any and all financial information in the Bank's possession concerning the
     Borrower, either Guarantor and any Subsidiary which has been delivered to
     the Bank by the Borrower, either Guarantor or any Subsidiary pursuant to

     the Bank by the Borrower, either Guarantor or any Subsidiary in connection
     with the Bank's credit evaluation of the Borrower, either Guarantor or any
     Subsidiary prior to entering into this Agreement; provided, that such

     Transferee or prospective Transferee shall first have executed and
     delivered to the Borrower a Confidentiality Agreement.

          (d)  The Bank shall have the right to collaterally assign its rights
     hereunder or under any other Loan Document to any Federal Reserve Bank in
     accordance with applicable law.

     SECTION 10.12  Other Transactions.  Nothing contained herein shall preclude
                    ------------------                                          
the Bank from engaging in any transaction, in addition to those contemplated by
this Agreement or any other Loan Document, with the Borrower or any of its
Affiliates in which the Borrower or such Affiliate is not restricted hereby from
engaging with any other Person.

     SECTION 10.13  Waiver of Jury Trial.  THE BANK, AND THE BORROWER HEREBY
                    --------------------                                    
KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVE ANY RIGHTS THEY MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON, OR ARISING OUT OF,
UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT, OR ANY
COURSE OF CONDUCT, COURSE OF DEALING, STATEMENTS (WHETHER VERBAL OR WRITTEN), OR
ACTIONS OF THE BANK, OR THE BORROWER.  THIS PROVISION IS A MATERIAL INDUCEMENT
FOR THE BANK ENTERING INTO THIS AGREEMENT.

     SECTION 10.14  Consent to Jurisdiction and Service of Process.  Any
                    ----------------------------------------------      
judicial proceedings brought against the Borrower with respect to this Agreement
or any Note may be brought in any state or federal court of competent
jurisdiction in the State of New York and by the execution and delivery of this
Agreement the Borrower accepts the nonexclusive jurisdiction of the aforesaid
courts.  Service of process may be made by any means authorized by federal law
or the law of New York.  A copy of any such process so served shall be mailed by
registered mail to the Borrower at its address set forth below its signature
hereto or at such other address as may be designated by the Borrower in a notice
to the Bank.  Nothing herein shall limit the right of any Bank to bring
proceedings against the Borrower in the courts of any other jurisdiction.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective officers thereunto duly authorized as of the day
and year first above written.

guaranty, and the performance by each of the undersigned of its obligations
hereunder, are within the corporate right, power, authority and capacity of such
undersigned and have been duly authorized by all necessary corporate action on
the part of such undersigned, and (b) this guaranty has been duly executed and
delivered on behalf of each of the undersigned and is the legal, valid and
binding obligation of such undersigned, enforceable in accordance with its

constitute a default under any law, any presently existing requirement or
restriction imposed by judicial, arbitral or any governmental

                                       4

permit any Liens upon any of the capital stock of the Debtor owned by such
undersigned except as permitted by the Loan Agreement.

     18.  Successors.  This guaranty shall be binding upon the undersigned, and
          ----------                                                           
upon the successors and assigns of the undersigned; and all references herein to
the Debtor and to such undersigned, respectively, shall be deemed to include any
successor or successors, whether immediate or remote, to such of the Debtor or
such undersigned.  The term "undersigned" as used herein shall mean all parties

WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK.  Wherever possible each
provision of this guaranty shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this guaranty
shall be prohibited by or invalid under such law, such provision shall be
ineffective to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
guaranty.

     20.  Captions.  Section captions used in this guaranty are for convenience
          --------

WAIVE ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO
ENFORCE OR DEFEND ANY RIGHTS UNDER THIS GUARANTY OR UNDER ANY
AMENDMENT, INSTRUMENT, DOCUMENT OR AGREEMENT DELIVERED OR WHICH

THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT
NOT BEFORE A JURY.

and delivery of this guaranty, each of the undersigned accepts the nonexclusive
jurisdiction of the aforesaid courts.  Service of process may be made by any
means authorized by federal law or the law of New York, as the case may be.  A
copy of any such process so served shall be mailed by registered mail to such
undersigned at its address set forth opposite its name on the signature page
hereto or at such other address as may be designated by such undersigned in a
notice to the Agent.  Nothing herein shall limit the right of the Agent or any
Bank to bring proceedings against any of the undersigned in the courts of any

such capacity, together with its successors and assigns, called "Bank"), each of
                                                                 ----           
the undersigned, hereby unconditionally guarantees the full and prompt payment

the Debtor or such undersigned for the benefit of creditors, or the commencement
of any case or proceeding in respect of the Debtor or such undersigned under any

if such event shall occur at a time when any of the Liabilities may not then be
due and payable, such undersigned will pay to the Bank forthwith the full amount
which would be payable hereunder by such undersigned if all Liabilities were
then due and payable.

     3.   Right of Setoff in Deposits and Other Property.  The Bank shall have a
          ----------------------------------------------

undersigned hereunder, set off, appropriate and apply toward the payment of such
amount, in such order of application as the Bank may elect) any and all

hereafter with the Bank.

     4.   Continuing Guaranty.  This guaranty shall in all respects be a
          -------------------                                           
continuing, absolute and unconditional guaranty, and shall remain in full force
and effect (notwithstanding, without limitation, the dissolution of any of the
undersigned or that at any time or from time to time all Liabilities may have
been paid in full), until all Liabilities (including any extensions or renewals
of any thereof) and all interest thereon and all expenses (including attorneys'
fees and legal expenses) reasonably paid or incurred by the Bank in endeavoring
to collect the Liabilities and in enforcing this guaranty shall have been
finally paid in full and all other obligations of each of the undersigned under
this guaranty shall have been satisfied.

     5.   Rescission or Return of Payment on Liabilities.  Each of the
          ----------------------------------------------              
undersigned further agrees that, if at any time all or any part of any payment
theretofore applied by the Bank to any of the Liabilities is or must be

without limitation, the insolvency, bankruptcy or reorganization of the Debtor),
such Liabilities shall, for the purposes of this guaranty, to the extent that
such payment is or must be rescinded or returned, be deemed to have continued in
existence, notwithstanding such application by the Bank, and this guaranty shall
continue to be effective or be reinstated, as the case may be, as to such
Liabilities, all as though such application by the Bank had not been made.

     6.   Bank Permitted to Take Certain Actions.  The Bank may, from time to
          --------------------------------------

security interest in any property to secure any of the Liabilities or any
obligation hereunder, (b) retain or obtain the primary or secondary obligation
of any obligor or obligors, in addition to the undersigned, with respect to any
of the Liabilities, (c) extend or renew for one or more periods (whether or not
longer than the original period), alter or exchange any OF the Liabilities, or
release or compromise any obligation of any of the undersigned hereunder or any
obligation of any nature of any other obligor with respect to any of the
Liabilities, (d) release or fail to perfect its lien upon or security interest
in, or impair, surrender, release or permit any substitution or exchange for,
all or any part of any property securing any of the Liabilities or any
obligation hereunder, or extend or renew for one or more periods (whether or not
longer than the original period) or release, compromise, alter or exchange any
obligations of any nature of any obligor with respect to any such property, and
(e) resort to the undersigned (or any of them) for payment of any of the
Liabilities, whether or not the Bank (i) shall have resorted to any property
securing any of the Liabilities or any obligation hereunder or (ii) shall have
proceeded against any other of the undersigned or any other obligor primarily or
secondarily obligated with respect to any of the Liabilities (all of the actions
referred to in preceding clauses (i) and (ii) being hereby expressly waived by
the undersigned).

     7.   Application of Payments.  Any amounts received by the Bank from
          -----------------------                                        
whatsoever source on account of the Liabilities may be applied by the Bank,
toward the payment of such of the Liabilities, and in such order of application,
as the Bank may from time to time elect.

     8.   Waiver of Subrogation.  Each of the undersigned hereby waives any
          ---------------------                                            
claim or other right which such of the undersigned may now have or hereafter

obligated with respect to any of the Liabilities that arises from the existence
or performance of the obligations of such of the undersigned under this
guaranty, including, without limitation, any right of indemnification or any
right of subrogation or other right to participate in any claim or remedy of the
Bank against the Debtor or any property securing any of the Liabilities, which
the Bank now has or hereafter acquires, whether or not such claim, right or
remedy arises in equity or under contract, statute or common law.  The
provisions of this paragraph are for the express benefit of the Debtor and each
other obligor primarily or secondarily obligated with respect to any of the
Liabilities as well as the Bank and may be enforced independently by the Debtor
and each such other obligor.

     9.   Waiver of Notice and Other Matters.  Each of the undersigned hereby
          ----------------------------------

guaranty is limited shall not in any way affect or impair the rights of the Bank
and the obligations of the undersigned under this guaranty.

     11.  Assignment of Liabilities.  The Bank may, from time to time to the
          -------------------------                                         
extent permitted under the Loan Agreement, without notice to the undersigned (or
any of them), assign or transfer any or all of the Liabilities or any interest
therein; and, notwithstanding any such assignment or transfer or any subsequent
assignment or transfer thereof, such Liabilities shall be and remain Liabilities
for the purposes of this guaranty, and each and every immediate and successive
assignee or transferee of any of the Liabilities or of any interest therein
shall, to the extent of the interest of such assignee or transferee in the
Liabilities, be entitled to the benefits of this guaranty to the same extent as
if such assignee or transferee were the Bank.

          ------------------------

or partial exercise by the Bank of any right or remedy shall preclude other or
further exercise thereof or the exercise of any other right or remedy; nor shall
any modification or waiver of any of the provisions of this guaranty be binding
upon the Bank except as expressly set forth in a writing duly signed and
delivered on behalf of the Bank.

     13.  Obligations Under Guaranty.  No action of the Bank permitted hereunder

Debtor or anyone else to assert any claim or defense as to the invalidity or
unenforceability of any such obligation, and no such claim or defense shall
affect or impair the obligations of the undersigned hereunder.  The obligations
of the undersigned under this guaranty shall be absolute and unconditional
irrespective of any circumstance whatsoever which might constitute a legal or
equitable discharge or defense of the undersigned (or any of them).  Each of the
undersigned hereby acknowledges that there are no conditions to the
effectiveness of this guaranty.

business of the Debtor which may come into the Bank's possession.

     15.  Senior Indebtedness.  Each of the undersigned hereby further warrants
          -------------------                                                  
and represents that the obligations of such undersigned under this Guaranty and
under each other Loan Document constitutes indebtedness senior to any
subordinated indebtedness of such undersigned.

     16.  Certain Representations.  The undersigned hereby further warrant and

the performance by each of the undersigned of its obligations hereunder, are
within the corporate right, power, authority and capacity of such undersigned
and have been duly authorized by all necessary corporate action on the part of
such undersigned, and (b) this guaranty has been duly executed and delivered on
behalf of each of the undersigned and is the legal, valid and binding obligation
of such undersigned, enforceable in accordance with its terms, the making and

violate or constitute a default under any law, any presently existing
requirement or restriction imposed by judicial, arbitral or any governmental
instrumentality or any agreement, instrument or indenture by which such
undersigned is bound.

     17.  Liabilities Limited.  Anything else in this guaranty notwithstanding,
          -------------------                                                  
each of the undersigned shall be liable under this guaranty only for the maximum
amount of such liability that can be hereby incurred without rendering this
guaranty, as it relates to such undersigned, voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer, and not for any
greater amount.

     18.  Successors.  This guaranty shall be binding upon the undersigned, and
          ----------                                                           
upon the successors and assigns of the undersigned; and all references herein to
the Debtor and to such of the undersigned, respectively, shall be deemed to

"Debtors"), howsoever created, arising or evidenced, whether direct or indirect,
 -------                                                                        
absolute or contingent or now or hereafter existing, are hereinafter called the
"Claims".  All Claims of the Bank under the Loan Agreement, the Notes and each
other Loan Document are hereinafter called the "Senior Claims", and all Claims
of each of the Subordinated Lenders are hereinafter called the "Junior Claims";
it being expressly understood and agreed that the term "Senior Claims", as used
herein, shall include, without limitation, any and all interest accruing on any
of the Senior Claims after the commencement of any suits or proceedings referred
to in Section 5, notwithstanding any provision or rule of law which might
      ---------                                                          
restrict the rights of the Bank, as against any of the Debtors or anyone else,
to collect such interest.

     SECTION 2.  Notice of Junior Liabilities, etc. any time when a Default
                 ----------------------------------                        
shall be existing, each of the Subordinated Lenders will promptly notify the
Bank of the creation of any Junior Claims and of the issuance of any promissory
note or other instrument of any of the Debtors to evidence any Junior Claims.
<PAGE>
 
     SECTION 3.  Subordination.  Except as expressly provided in Section 4 of
                 -------------                                               
this Agreement, the payment of all Junior Claims shall be postponed and
subordinated to the payment in full of all Senior Claims, and each Subordinated
Lender agrees not to seek to collect any amounts owing to it by any of the
Debtors under or in connection with any settlement of any Junior Claim or any
judgment entered in favor of any or all Claimants with respect to a Junior
Claim, or to seek to obtain any other distributions in money or property or of
any other kind whatsoever in respect of any Junior Claims, nor shall any
property or assets of any of the Debtors be applied to the purchase or other
acquisition or retirement of any Junior Claims.

     SECTION 4.  Permitted Payments.  Provided that both before and after giving
                 ------------------                                             
effect to any such payment, no Default shall have occurred and be continuing,
notwithstanding Section 3 above, any of the Debtors may pay to the Subordinated
Lenders, and the Subordinated Lenders may accept from such Debtors, any payments
of principal and interest on all Junior Claims.  In the event that a Default
shall be existing, none of the Subordinated Lenders shall ask, demand, take or
receive from any Debtor by setoff or in any other manner any payment in respect
of any Junior Claims until such Default ceases to exist or all Senior Claims
shall have been fully paid in cash and performed and all of the Commitments
shall have been terminated.

     SECTION 5.  Bankruptcy, Insolvency, etc.  In the event of any dissolution,
                 ---------------------------                                   
winding up, liquidation, readjustment, reorganization or other similar
proceedings relating to (a) any Debtor or (b) the respective assets or
properties of any Debtor, whether such proceeding or proceedings are voluntary
or involuntary, partial or complete, and whether in bankruptcy, insolvency or
receivership, or upon an assignment for the benefit of creditors, or any other
marshalling of the assets and liabilities of any Debtor or any sale of all or
substantially all of the assets of any Debtor, or otherwise, the Subordinated
Lenders hereby acknowledge and agree that the Senior Claims shall first be paid
in full before any Subordinated Lender shall be entitled to receive and/or to
retain any payment or distribution in respect of any of the Junior Claims.  In
order to implement the foregoing, (i) all payments and distributions of any kind
or character in respect of any of the Junior Claims to which any Subordinated
Lender would be entitled if the Junior Claims were not subordinated pursuant to
this Agreement shall be made directly to the Bank, (ii) each Subordinated Lender
shall promptly file a claim or claims, in the form required in such proceedings,
for the full outstanding amount of the Junior Claims, if any, by or belonging to
such Subordinated Lender, and shall cause said claim or claims to be approved
and all payments and other distributions in respect thereof to be made directly
to the Bank, and (iii) each Subordinated Lender hereby irrevocably agrees that,
if such Subordinated Lender shall fail to file any such claim referred to in the
preceding clause (ii), the Bank may, at its sole discretion, in the name of each
Subordinated Lender or otherwise, demand, sue for, collect, receive and accept
receipt for any and all such payments or distributions, and file, prove, and
vote or consent in any such proceedings with respect to, any and all claims of
each Subordinated Lender relating to the Junior Claims.

     SECTION 6.  Payments Held in Trust.  In the event that any Subordinated
                 ----------------------                                     
Lender receives any payment or other distribution of any kind or character from
any source whatsoever in respect of any of the Junior Claims, other than as
expressly permitted by the terms of this Agreement, such payment or other
distribution shall be received in trust for the Bank, and each Subordinated
Lender shall promptly turn over any such payment or distribution to the Bank.
Each of the Subordinated Lenders will keep, and cause each Debtor to keep, this
Agreement with and as part of its respective books and records, and will cause
to be clearly inserted in any promissory note or other instrument which at any
time evidences any of the Junior Claims a statement to the effect that the
payment thereof is subordinated in accordance with the terms of this Agreement.
Each of the Subordinated Lenders will execute such further

                                       2
<PAGE>
 
documents or instruments and take such further action as the Bank may from time
to time reasonably request to carry out the intent of this Agreement.

     SECTION 7.   Application of Payments, No Subrogation.  All payments and
                  ---------------------------------------                   
distributions received by the Bank in respect of the Junior Claims, to the
extent received in or converted into cash, may be applied by the Bank first to
the payment of any and all expenses (including attorneys' fees and legal
expenses) paid or incurred by the Bank in enforcing this Agreement or in
endeavoring to collect or realize upon any of the Senior Claims or the Junior
Claims or any security therefor, and any balance thereof may, solely as between
each of the Subordinated Lenders and the Bank, be applied by the Bank in such
order of application as the Bank, in its sole discretion, may elect from time to
time, toward the payment of the Senior Claims remaining unpaid; provided,
                                                                ---------
however, as among the Debtors on the one hand and each of the Subordinated
- -------                                                                   
Lenders on the other hand, and their respective creditors, no such payments or
distributions of any kind or character shall be deemed to be payments or
distributions in respect of the Senior Claims.  Notwithstanding any such
payments or distributions received by the Bank in respect of the Senior Claims
or the Junior Claims, which payments or distributions are applied by the Bank
toward the payment of the Senior Claims, each of the Subordinated Lenders shall
be subrogated to the then existing rights of the Bank, if any, in respect of the
Senior Claims only at such time as this Agreement shall have been discontinued

          (b) Environmental Matters: Any Rheinbraun Liability and forty-seven
              ---------------------
(47%) of any and all Loss which any member of the Coal Group incurs, arising or
resulting from or relating to (i) the failure of any member of the Coal Group

any kind, and to have filed all notifications of any kind on or prior to the
Closing Date, required for the generation, handling, storage, transportation,

               --------------------------------- 
forty-seven percent (47%) of any and all Loss which any member of the Coal Group
incurs, arising from or relating to Pre-Closing Coal Group Litigation, excluding

                                     -23-
<PAGE>
 
to cover all material liability of the Coal Group for Taxes (excluding, for
purposes of determining such adequacy, interest and penalties) for any taxable

required so to indemnify Rheinbraun or CEI in respect of any of the matters

section 4.4, above) until the aggregate amount of all such Rheinbraun Liability
and Loss incurred by members of the Coal Group (calculated on a pre-tax basis)
exceeds twenty million dollars ($20,000,000), in which case Du Pont shall so
indemnify Rheinbraun or CEI, as the case may be, from and against all such
Rheinbraun Liability and Loss, including the first twenty million dollars
($20,000,000) thereof (but such amount of Loss shall be calculated on an after-
tax basis and 

                                     -24-
<PAGE>
 
subject to the provisions of Section 9.2.(b)), but in no event shall the
obligations of Du Pont under this Article in the aggregate exceed Five Hundred
Million United States Dollars ($500,000,000).

          9.2  Rules of Construction.
               ---------------------

               (a)  If a claim for indemnification shall appear to fall under
paragraph (a) of section 9.1 and any other paragraph thereof, the paragraph
other than paragraph (a) of the greatest particularity in relation to such claim
shall govern exclusively. If a claim for indemnification shall appear to fall
under both paragraph (b) of Section 9.1 and paragraph (c) thereof, the former
paragraph shall govern exclusively.

               (b)  Any amount indemnifiable under Section 9.1 shall be reduced
by the amount by which the income tax liability of the Coal Group or Rheinbraun,
as the case may be, is reduced as a result of the relevant Loss; provided, that
the prompt payment when due of the entire indemnifiable amount (as adjusted to
reflect any good faith estimate of such reduction in income tax liability) shall
not be affected or delayed unless such actual reduction in income tax liability
shall have been finally determined prior to such due date. When such actual
reduction in income tax liability shall be finally determined after payment of
the entirety of such adjusted indemnifiable amount, there shall be an
appropriate reconciling payment.

          9.3  Notice of Claim for Indemnification. Upon receipt by Rheinbraun
               -----------------------------------
or CEI of notice or the obtaining by Rheinbraun or 

                                     -25-
<PAGE>
 
CEI of evidence of any claim upon which indemnification may be sought hereunder,
it shall give written notice of the same to Du Pont. Such notice shall describe
the nature of the claim and, wherever possible, contain an estimate of the
amount of such claim. If any such claim relates to claims asserted by a third
party against Rheinbraun or against any member of the Coal Group (the
"defendant"), and if Du Pont desires to contest the same, Du Pont shall within
ten days after the receipt of a notice pursuant to Section 9.4(a) so notify the
defendant, failing which the defendant shall have the right to undertake the
defense, compromise or settlement of the same (acting in good faith) on behalf
of and for the account and risk of Du Pont. If Du Pont so notifies the defendant
that Du Pont elects to contest the claim, then Du Pont shall be entitled to
control the defense thereof by counsel of its own selection (the identity of
which counsel shall be subject to the consent of the other party, which consent
shall not be unreasonably withheld) and at its own expense. Du Pont and the
defendant shall give each other all information and assistance which each may
reasonably request in defending any matter hereunder.

          9.4  Indemnity Notice Periods.
               ------------------------

               (a)  Save as otherwise provided in this section 9.4, any claim

asserted by Rheinbraun or CEI, as the case may be, if asserted by written notice
pursuant to Section 9.3 to Du Pont not later than August 31, 2000.

                                     -26-
<PAGE>
 
               (b)  Any claim for indemnification under section 9.1(b) shall be

asserted by written notice pursuant to section 9.3 at any time not later than
the fourth anniversary of the Closing.

               (c)  Any claim for indemnification under section 9.1(c) shall be
sufficiently and timely asserted by Rheinbraun or CEI, as the case may be, if
asserted by written notice pursuant to section 9.3 within ninety (90) days after
all administrative and judicial proceedings in respect of all matters the
subject of such section shall have been settled or shall have concluded by the
entry of a final judgment, issuance of an arbitral award or otherwise.

               (d)  Any claim for indemnification with respect to a liability
for Taxes (as defined in section 9.1(d)) shall be sufficiently and timely
asserted by Rheinbraun or CEI, as the case may be, if asserted by written notice
pursuant to section 9.3 within ninety (90) days after all administrative and any
judicial proceedings have concluded and there has been a final determination of
the Taxes due which are the subject of such claim, and shall be barred unless so
asserted.

               (e)  Any claim for indemnification under section 9.1(e) may be
asserted at any time.

               (f)  Notwithstanding any other provision of this Article, any
claim for indemnification by a party based upon a willful and fraudulent
misrepresentation by the other party may be

                                     -27-
<PAGE>
 
asserted by the party seeking indemnification by written notice pursuant to
section 9.3 within one hundred and eighty (180) days after such party receives
or obtains actual knowledge of such misrepresentation.

          9.5  Exclusive Remedies. Following the Closing, except in the case of
               ------------------
fraud, the indemnities set forth in this Article shall be the only remedies
available to a party entitled to indemnification with respect to the matters
giving rise to such indemnification.

          9.6  Coexistence of SEA Agreement.  Neither this Article nor any 
               ---------------------------
indemnification made under this Article shall affect or lessen the obligations
of any party as indemnitor under the SEA Agreement, and neither the SEA
Agreement nor any indemnification made under the SEA Agreement shall affect or
lessen the obligations of any party as indemnitor under this Article; provided,
                                                                      --------
that, for purposes of administering claims under the SEA Agreement and this
- ----                                            
Agreement, the following rules shall apply:

          (a)  a Loss any portion of which may be indemnifiable under both
Agreements (a "Common Loss") shall first be charged only against any applicable
exclusion in the SEA Agreement (set forth in Section 11.1 (d), (e) or (f) of the
SEA Agreement, as the case may be) and thereafter shall be indemnified by Du
Pont to the extent required by the SEA Agreement, subject to the $20,000,000
threshold set forth in the last paragraph of Section 11.1 of the SEA Agreement
if not yet satisfied;

                                     -28-
<PAGE>
 
          (b)  once any applicable exclusion or threshold under the SEA
Agreement has been satisfied, any Common Loss incurred thereafter shall, to the
extent not charged against any exclusion or threshold or indemnified by Du Pont
under the SEA Agreement, be treated as a Loss indemnifiable under this
Agreement, subject to any applicable exclusions or threshold under this
Agreement; and

          (c)  a Loss indemnifiable under only one of the SEA Agreement and this
Agreement shall be indemnified only under, and to the extent required by, the
applicable Agreement, subject to the exclusions and threshold of such Agreement;
it is understood that no Loss which might have been indemnifiable under the SEA
Agreement but is not because of a failure to give timely notice thereof in
accordance with the provisions of the SEA Agreement shall be treated as a Common
Loss.

          9.7  Knowledge of Claims.  Each representation and warranty made by a
               -------------------
party to this Agreement is made with the intention that the recipient thereof
may rely upon the accuracy thereof, and the effect of each such representation
and warranty shall not be lessened by any investigation independently conducted
by such recipient.

          9.8  Notice to Du Pont of Common Loss Settlements.  Prior to settling
               -------------------------------------------- 
any proceeding or claim (including without limitation any tax dispute,
arbitration or claim) for an amount in excess of $1,000,000 (in respect of any
tax claim) or in excess of $5,000,000 (in respect of any other claim) that is

                                     -29-
<PAGE>
 
subject to the indemnification provisions hereof (without regard to the
exclusion and threshold amounts specified herein) and that would give rise to a
Common Loss, CEI shall give Du Pont as much notice of such settlement as is
reasonably practicable in the circumstances and opportunity to comment thereon.

following the effective date of this Agreement, then this Agreement may be
terminated at any time thereafter by any party upon written notice delivered to
all other parties hereto; provided, that, this Article does not confer on any
                          --------
party the right to terminate this Agreement if all conditions to the performance
by such party of its obligations under this Agreement have been fulfilled or
waived on or before such 120th day, and a party may not terminate this Agreement
on the ground of non-fulfillment of a condition if such non-fulfillment was

                                 MISCELLANEOUS

          15.1  Entire Agreement.
                ----------------

                (a)  This Agreement constitutes the entire agreement between the
parties on the subject matter hereof, and supersedes any and all prior
agreements and undertakings between the parties hereto with respect to the
subject matter hereof.

                (b)  Nothing in this Agreement shall affect or lessen the rights
and obligations of the parties (including indemnification obligations) under the
SEA Agreement.

          15.2  Counterparts.  This Agreement may be executed in any number of
                ------------ 
counterparts, each of which shall be deemed to constitute an original of the
same Agreement, and all counterparts together shall constitute one single
agreement, which shall be effective upon the execution hereof by all the parties
hereto. A complete set of counterparts shall be made available to each party
hereto.

          15.3  Partial Invalidity.  In the event that one or more of the
                ------------------       
provisions of this Agreement shall for any reason be held to be invalid,
illegal, or unenforceable in any respect, such invalidity, illegality, or
unenforceability shall not affect any other provision of this Agreement, and
this Agreement shall be construed as if such invalid or illegal or unenforceable
provision had never been contained herein.

          15.4  Interpretation.  The Table of Contents and the headings of the
                --------------

<PAGE>
 
included for convenience of reference only and shall not affect the
interpretation of any provision of this Agreement. The assumption of
responsibility for the drafting of this Agreement or any portion hereof by a

          15.5  Amendments, Waivers and Consents.  For the purposes of this
                -------------------------------- 
Agreement, except as otherwise specifically set forth herein, no course of
dealing between any of the parties and no delay on the part of any party hereto
in exercising any rights hereunder shall operate as a waiver of the rights
hereof. No covenant or other provision hereof may be waived otherwise than by a
written instrument signed by the party so waiving such covenant or other
provision; provided, that, except as otherwise stated herein, changes in or 
           --------                                  
additions to, and any consents required by, this Agreement may be made, and
compliance with any term, covenant, condition or provision set forth herein may

                --------- 
regulations (including regulations of a securities exchange) of the United
States, any state thereof or the Federal Republic of Germany, no public release

                                     -34-
<PAGE>
 
such release or announcement shall be required by any such laws or regulations,
the party required to make the release or announcement shall allow the other
parties reasonable time to comment on such release or announcement in advance of
its issuance.

          15.7  Further Assurances. Each party will execute and deliver such
                ------------------
further instruments, shall obtain all necessary consents, and shall take such
further actions as may be reasonably requested by the other parties to confirm
and carry out the transactions contemplated by this Agreement.


                                  ARTICLE XVI

                          GOVERNING LAW; ARBITRATION


          16.1  Governing Law. The validity, performance, interpretation and
                -------------
other incidents of this Agreement shall be governed by the internal law of the
State of New York.


          16.2  Arbitration
                -----------

                (a)  Any dispute, controversy or claim arising out of or
relating to this Agreement, or the interpretation, breach, termination or
invalidity thereof, shall be finally settled by arbitration in London, England,
in accordance with the Rules of the London Court of International Arbitration
("LCIA") as in force on the date hereof by three arbitrators as hereinafter
provided. The language of any arbitral proceeding shall be English. For the
purposes of this section 16.2, Du Pont and DEC shall be deemed a single party,
Rheinbraun and CEI shall be deemed a single party,

                                     -35-
<PAGE>
 
and all procedural rights and obligations of such party shall be exercised and
discharged, respectively, by Du Pont and Rheinbraun.

                (b)   The arbitral tribunal shall be composed of three
arbitrators appointed as follows:

                (i)   Each party shall nominate an arbitrator, and the two
                      arbitrators so nominated shall appoint a third arbitrator
                      who shall act as president of the tribunal;

                (ii)  if either party shall fail to nominate an arbitrator
                      within thirty (30) days after receiving notice of the
                      nomination of an arbitrator by the other party, such
                      arbitrator shall, at the written request of such other
                      party, be appointed by the LCIA;

                (iii) if the two arbitrators so nominated shall fail to agree
                      upon a third arbitrator within thirty (30) days after the
                      appointment of the second arbitrator, the third arbitrator
                      shall, at the written request of either party, be
                      appointed by the LCIA;

                (iv)  should a vacancy arise because any arbitrator dies,
                      resigns, refuses to act, or becomes incapable of
                      performing his functions, the vacancy shall be filled by
                      the method by which that arbitrator was originally
                      appointed.

                                     -36-
<PAGE>
 
          (c)  Any arbitration proceeding hereunder may include claims or
counterclaims, if any, arising under and chargeable against a party to this
Agreement who is also a party to the Shareholders Agreement, the Shareholders
Amendatory Agreement, the SEA Agreement, or all said agreements. If more than
one arbitration proceeding shall be pending hereunder concurrently, then, upon
the written agreement of all parties engaged in such proceedings, the several
proceedings may be consolidated by the LCIA into one proceeding upon the terms
of such agreement and the Rules of the LCIA.

          (d)  The parties agree that irreparable damage would occur if any
provision of this Agreement were not performed in accordance with its specific
terms or were otherwise breached, and that the arbitral tribunal shall
consequently have power to grant injunctions (preliminary and permanent) and
specific performance in addition to other relief. The arbitral tribunal shall
also grant to any party, upon its request, broad discovery of relevant,
unprivileged documents controlled by the other party. Nothing herein shall limit
the right of any party, before and during any such arbitration proceeding, to
have recourse to such provisional judicial remedies, including preliminary
injunction and attachment, as would be available in the absence of this Section;
provided, that any legal action seeking such provisional judicial remedies shall
be brought in state or federal courts in Wilmington, Delaware, if brought
against a domiciliary of the United States, or in the courts of Cologne,
Germany, if brought

                                     -37-
<PAGE>
 
against a domiciliary of Germany, or in the courts of England (irrespective of
the domiciles of the parties). Judgment upon any arbitral award may be entered
in any court having jurisdiction. The parties agree to exclude the right of
appeal to any court in England from any award of the arbitral tribunal, and to
exclude the right to apply to any court in England for the determination of any
question of law arising in the arbitration.

          (e)  During the pendency of an arbitration proceeding hereunder, any
party to the proceeding may continue to perform its obligations hereunder
without prejudice to its claims, defenses, counterclaims, or any resulting
award, and such party shall continue to perform such obligations unless its
claims, defenses, or counterclaims assert in such proceeding that, in
consequence of a material breach of this Agreement by another party to such
proceeding or the failure of a condition of such obligations, it is excused from
continued performance of this Agreement.

          (f)  Each party agrees that any request for arbitration, answer
thereto or other paper for such arbitration, or complaint, answer thereto or
other paper for such judicial proceeding, shall be sufficiently served on a
party if delivered personally or by express mail (return receipt requested) to
the address specified for such party in this Agreement, such delivery to be
effective only upon actual receipt.

                           Form of Counter-Guaranty
                           ------------------------

     COUNTER-GUARANTY made as of __________________ by RHEINBRAUN AG, a
corporation duly organized and existing under the laws of Germany (hereinafter
the "Guarantor").

                                  WITNESSETH:

     WHEREAS, Consol Energy Inc. and E.I. du Pont de Nemours and Company ("Du
Pont") and an Affiliate, have entered into a Share Purchase Agreement dated
________________ (the "Agreement"); and

     WHEREAS, Section 8.9 of the Agreement contemplates that the Guarantor shall
execute and deliver in favor of Du Pont a counter-guaranty in respect of any
liability Du Pont may incur as a result of guaranties or indemnities heretofore
given by Du Pont or certain of its Affiliates not within the Coal Group (as
defined in the Agreement) of certain obligations of members of the Coal Group,
as set forth in Exhibit B of the Agreement;

     NOW, THEREFORE, the Guarantor, for and in consideration of Du Pont's
entering into the Agreement and for U.S. $1.00 and other good and valuable
consideration, agrees as follows:
<PAGE>
 
     1.  As used in this Counter-Guaranty, (i) the term "Reimbursable Payment"
shall mean a payment made by Du Pont (or such Affiliate) to the beneficiary of a
guaranty or indemnity set forth in Exhibit B of the Agreement ("Beneficiary"),
up to the maximum amount of such guaranty or indemnity shown on said Exhibit,
that is made in discharge of (a) a final judgment or order of a court of
competent jurisdiction in favor of such Beneficiary respecting the claims of
such Beneficiary under such guaranty or indemnity, or (b) a written agreement
between Du Pont (or such Affiliate) and such Beneficiary settling with finality,
and releasing Du Pont (or such Affiliate) from further obligations respecting
such claims of such Beneficiary under such guaranty or indemnity to which
agreement Rheinbraun shall have consented in writing prior to the execution
thereof (which consent shall not be unreasonably withheld), and (ii) the term
"Expenditures" shall mean all reasonable expenses of Du Pont (or such Affiliate)
paid to any third party that are incidental to a claim referred to in (i) above,
provided however that Du Pont (or such Affiliate) shall have consulted with
Rheinbraun prior to incurring such expenses. Any other term not defined herein
shall have the same meaning given it in the Agreement.

     2.  Within 30 days after Du Pont (or such Affiliate) shall have received
written notice of a claim, or threatened claim, by a Beneficiary, Du Pont (or
such Affiliate) shall give written 

                                       2
<PAGE>
 
notice thereof to Rheinbraun together with a photocopy of such notice. Within 30
days after Du Pont (or such Affiliate) shall have made a Reimbursable Payment to
such Beneficiary and/or shall have incurred Expenditures, it shall give written
notice to Rheinbraun stating the amount paid or incurred and shall furnish to
Rheinbraun documentary evidence of the making of such Reimbursable Payment
and/or the incurring of such Expenditures, or if no such documentary evidence
exists, a certificate signed by an officer of Du Pont (or of such Affiliate)
attesting to the making of such Reimbursable Payment or the incurring of such
Expenditures. In the case of a payment of the character described in
subparagraph 1(i)(a), above, Du Pont (or such Affiliate) shall also furnish to
Rheinbraun a photocopy of the relevant judgment or order, and, in the case of a
payment of the character described in subparagraph 1(i)(b), above, Du Pont (or
such Affiliate) shall also furnish to Rheinbraun a photocopy of the relevant
written agreement as executed by Du Pont (or such Affiliate) and such
Beneficiary.

     3.  Within 30 days after the receipt by Rheinbraun of documents specified
in and conforming to paragraph (2), above, Rheinbraun shall pay to Du Pont (or
such Affiliate) the amount of the Reimbursable Payment and/or Expenditures made
or incurred by Du Pont (or such Affiliate), and Du Pont (or such Affiliate)
shall, within 10 days of receipt of such payment from Rheinbraun, 

                                       3
<PAGE>
 
assign to Rheinbraun, absolutely, by written instrument satisfactory to
Rheinbraun, all rights, by way of subrogation or otherwise, that Du Pont (or
such Affiliate) shall acquire against the principal debtor by reason of such
Reimbursable Payment or Expenditures.

     4.  No Beneficiary shall, by reason of this Counter-Guaranty, acquire
rights against Rheinbraun as a third-party beneficiary hereof or otherwise.

     5.  Subject to Section 7 hereof, Du Pont (for itself and all such
Affiliates) and Rheinbraun each hereby agree that, in respect of any rights
either of them may acquire by subrogation or otherwise, it shall not, without
the consent of the other, proceed against any member of the Coal Group by reason
of any Reimbursable Payment or Expenditures made or incurred by Du Pont (or such
Affiliate) or by reason of any payment made by Rheinbraun to Du Pont (or such
Affiliate) pursuant to paragraph 3 hereof.

     6.  The following provisions of the Agreement are incorporated by reference
as if fully set forth herein:  Article XIV (Notices) and Sections 16.1
(Governing Law) and 16.2 (Arbitration).

                                       4
<PAGE>
 
     7.  Rheinbraun understands and agrees that Du Pont (or such Affiliate) will
continue to follow its standard practice of billing back to the Coal Group 100%
of all Reimbursable Payments, Expenditures and insurance, surety or other
premiums or expenses paid to maintain in effect the guaranties and indemnities
set forth in Exhibit B of the Agreement. To the extent such billings are paid by
the Coal Group, Du Pont (and each such Affiliate) shall not be entitled to make
a claim for the amount of such billings against Rheinbraun hereunder, and if any
such billings are paid by the Coal Group after payment of the same by Rheinbraun
to Du Pont hereunder, Du Pont shall promptly refund to Rheinbraun the amount of
such payment.

     8.  This Counter-Guaranty is made and given in replacement of that certain
Counter-Guaranty dated as of December 31, 1991 (the "Prior Counter-Guaranty")
made by the Guarantor in favor of Du Pont. The parties agree that the prior
Counter-Guaranty is hereby terminated and declared to be void as of the date
thereof.

                                       5

     IN WITNESS WHEREOF, the Guarantor has executed this Counter-Guaranty as of
the day and year first above written.

          WHEREAS, Du Pont, DEC, CEI, and Rheinbraun have entered into an Option

made pursuant to a Share Purchase Agreement in form attached as Exhibit A to the
Option Agreement (the "SPA");

          WHEREAS, the parties hereto intend that the exercise of the Option
will vest in Rheinbraun control over CEI, while expiry of the Option will

prejudice to its right to dispose of Class A Shares under the Shareholders'
Agreement);
<PAGE>
 
          WHEREAS, in consequence of the foregoing, the parties hereto are

of the Option the Shareholders' Agreement shall be further amended as herein
provided;

          NOW, THEREFORE, the parties hereto agree as follows:

                                  ----------
                              Exercise of Option
                              ------------------

          1.   Rheinbraun Control; Suspension of Shareholders' Agreement. If
               ---------------------------------------------------------
Rheinbraun shall exercise the Option, then, effective immediately upon the
exercise of the Option, the following provisions shall apply:

          (a)  Rheinbraun shall assume exclusive managerial control over the
Coal Group and, to that end, (i) Du Pont shall cause each of the directors of
CEI nominated by Du Pont to deliver to CEI, with a copy to Rheinbraun, written
resignations from all directorships in the Coal Group held by him, and (ii) Du
Pont shall cause DEC to execute and deliver to Rheinbraun its irrevocable proxy,

Class A Shares in all respects, as such officers may determine; and,

          (b)  All provisions of the Shareholders' Agreement shall be suspended
and without contractual force except the following: sections 4.2 (subject,

of the Closing, then, automatically and without the necessity of further action
by the parties, (a) the Shareholders' Agreement shall terminate and be of no
further force or effect as of the Closing Date, and (b) each of the parties
hereto shall be deemed to have released and forever discharged every other party
to the Shareholders' Agreement from every liability and obligation that any of
them may have to the releasing party arising from the making and performance of

provided therein, or otherwise cancelled or discharged, without consummation of
the Closing, then, as of the date of such termination, cancellation or
discharge, (a) the resignations and proxy delivered pursuant to section 1 of
this Article II shall be void, and said directors (or their respective

                                       4
<PAGE>
 
successors appointed by Du Pont) shall reassume the directorships from which
they resigned and (b) the Shareholders' Agreement shall be reinstated and
continue in full force and effect and, to the extent practicable, the rights and
obligations of the parties to the Shareholders' Agreement, and the status of the
boards of directors of the Coal Group and the voting rights of DEC as holder of
the Class A Shares, shall be restored to their status as of the date and prior
to the execution hereof.

                                  ARTICLE III

                                Public Offering
                                ---------------

          1.   Right to Make Offering. If the Option shall expire unexercised,
               ----------------------
Du Pont shall be entitled to dispose of all or part of the Class A Shares in the
manner, and upon the conditions, specified in this Article and in Exhibit B
(Registration Rights), annexed hereto. For the purposes of this Amendatory
Agreement, Du Pont shall include DEC.

          2.   (a)  Procedures. Until December 31, 2001, Du Pont may distribute
                    ----------
Class A Shares to the public by means of (i) a spin-off stock dividend to
shareholders of Du Pont or (ii) a registered public offering pursuant to an
Underwriting Agreement as provided in Exhibit B. Not more than 60 days after
expiry of the Option, Du Pont shall give written notice to Rheinbraun and CEI
(the "2(a) Notice") of the method that it has elected to employ to make such
distribution and shall thereafter proceed according to such method; provided,
                                                                    --------  
that, Du Pont may amend the

<PAGE>
 
2(a) Notice once, not more than 180 days after expiry of the Option. The 2(a)
Notice shall include any proposal of Du Pont to change the capitalization of
CEI, by stock-split or otherwise, for the purposes of such distribution, and, if
Rheinbraun and CEI shall consent to such proposal (which consent shall not be
unreasonably withheld), corresponding changes shall be made in the Certificate
Incorporation and By-laws of CEI to give effect thereto. Any shares issued by
CEI in exchange for or in lieu of Class A Shares shall be deemed Class A Shares
for the purpose hereof. 



          (b)  Breadth of Distribution. In any public offering made pursuant to
               -----------------------
this Article and Exhibit B, Du Pont shall cause its underwriters to (i) effect
as wide a distribution of the Class A Shares as is practicable; (ii) prevent the
sale of Class A Shares to any person that would, following such sale,
beneficially own more than 4.9% of the outstanding shares of CEI after
completion of such offering; and (iii) treat Rheinbraun equally with
institutional investors and other offerees to whom Class A Shares are offered
for sale in the first such offering.

          (c)  Rheinbraun Cooperation. In connection with any public offering
               ---------------------- 
made pursuant to this Article and Exhibit B, Rheinbraun will use its reasonable
best efforts to (i) cause CEI to perform its obligations under this Article and
Exhibit B, and (ii) take such other actions as are reasonably requested by Du
Pont, or required by law, to expedite or facilitate the registration,
qualification or distribution of the number of 

                                       6
<PAGE>
 
Class A Shares included in such offering in accordance with this Article and
Exhibit B.

                                  ----------

                      Effects on Shareholders' Agreement
                      ----------------------------------

          1.   Complete Disposition. If Du Pont and DEC shall dispose of all

Class A Shares in conformity with Article III hereof, then, as of the date of
the final such disposition, (a) the Shareholders' Agreement shall terminate and
be of no further force or effect, and (b) each of the parties hereto shall be
deemed to have released and forever discharged every other party to the
Shareholders' Agreement from every liability and obligation that any of them may
have to the releasing party arising from the making and performance of the
Shareholders' Agreement.

          2.   Partial Disposition.  So long as Du Pont shall own any of the
               -------------------                                          
Class A Shares, the Shareholders' Agreement (including section 4.2 thereof)
shall be binding on Du Pont, and shall apply to such Shares, in accordance with
its terms as amended heretofore and hereby; provided, that, if part of the Class
                                            --------  ----                      
A Shares shall have been distributed in a public offering in conformity with
Article III hereof, only the following provisions of the Shareholders' Agreement
shall continue so to bind Du Pont: sections 4.2 as amended by section 3 of this
Article (for the purpose of which Du Pont and Rheinbraun shall be deemed the
sole 

                                       7

shareholders of CEI), 6.4, 7.1 (in relation to Class A Shares held by Du Pont),
7.2, 7.3, and 7.5 through 7.12 (inclusive).

               --------------------------                             
unexercised, section 4.2.1 of the Shareholders' Agreement shall be deemed

Section 4.2.1) annexed hereto.

                                   ARTICLE V
                                   ---------

                                 Miscellaneous
                                 -------------

          1.   Assignment.  By written notice to Rheinbraun and CEI, Du Pont may
               ----------                                                       
nominate a Subsidiary of Du Pont to exercise the rights granted by Article III
hereof.  Any other purported assignment of any right or privilege by one party
hereto without the prior written consent of all other parties hereto shall be
void.

          2.   Incorporation by Reference. Sections 7.4 through 7.12 (inclusive)
               --------------------------   
of the Shareholders' Agreement are incorporated by reference as if fully set

                                               ---------------------------------


                              REGISTRATION RIGHTS

          1.1.  Agreement to Register.  CEI agrees to register the Class A 
                ---------------------     
Shares, any other securities issued in exchange therefor (including by way of
stock split or in connection with a combination of shares, recapitalization, or
otherwise) and any other securities issued as a dividend thereon (the
"Registrable Securities") upon the terms and subject to the conditions set forth
in this Exhibit B and in the Amendatory Agreement to which this Exhibit is
annexed.

          (a)   Demand Registration.  On not more than two occasions prior to 
                -------------------
December 31, 2001, if Du Pont (i) requests in writing (a "Registration Request")
that CEI register the sale or other distribution under the Securities Act of
1933, as amended (the "Securities Act") of any of the Registrable Securities
(which request shall specify the number of Registrable Securities intended to be
offered and sold), (ii) expresses Du Pont's present intent to offer such
Registrable Securities for distribution, (iii) describes the nature or method of
the proposed offer and sale thereof, and (iv) undertakes to provide all such
information and materials relating to Du Pont and to take all such action as may
be required of Du Pont in order to permit CEI to comply with all applicable
requirements of the Securities and Exchange Commission (the "Commission") and to
obtain acceleration of the effective date of the registration statement
therefor, CEI shall use all reasonable efforts to cause the offering of the
Registrable Securities so specified in such request to be registered as soon as
reasonably practicable so as to permit the sale or other distribution by Du Pont
of the Registrable Securities specified in the Registration Request, and shall
in connection therewith prepare and file on an appropriate form, as CEI shall
reasonably determine, a registration statement under the Securities Act to
effect such registration. Notwithstanding any provision to the contrary
contained herein, CEI shall not be required to file any registration statement
pursuant to this section 1.1(a) in the following circumstances:

                (i)   if, in the reasonable judgment of Rheinbraun or CEI, a
registration at the time and on the terms requested would materially adversely
affect any financing by CEI that had been contemplated by Rheinbraun or CEI
prior to the notice by Du Pont requesting registration, CEI shall not be
required to commence using its best efforts to effect a registration pursuant to
this section until the earliest of (1) 90 days after the completion of such
financing, (2) the termination of any "black out" period 
<PAGE>
 
required by the underwriters, initial purchasers or placement agents, if any, in
connection with such financing or (3) promptly after abandonment of such
financing;

                (ii)  if, while a Registration Request is pending pursuant to
this section, Rheinbraun or CEI determines in good faith, based on the advice of
counsel, that proceeding with the registration would require the disclosure of
material information that Rheinbraun or CEI has a bona fide business purpose for
preserving as confidential, or CEI is unable to comply with Commission
requirements, CEI shall not be required to effect such pending registration
statement until the earlier of (1) the date upon which such material information
is disclosed to the public or ceases to be material or (2) 120 days after the
date CEI makes such determination; and

                (iii) if Rheinbraun and CEI shall not have received undertakings
reasonably satisfactory to them from any underwriter or underwriters to
indemnify and hold them harmless, each of their directors and officers, and
every other controlling person of them, from and against any and all loss,
damage, liability, cost or expense to which they, any director or officer of
them, or every other controlling person of them may become subject under the
Securities Act or otherwise, insofar as such losses, damages, liabilities, costs
or expenses (A) are caused by any untrue or alleged untrue statement of any
material fact contained in the registration statement or prospectus included
therein, as amended or supplemented, or (B) arise out of or are based upon the
omission or the alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading, in each case to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was so made in conformity with written information furnished by
such underwriter or underwriters.

                (iv)  The right of Du Pont to exercise registration rights
pursuant to section 1.1(a) shall be subject to the condition that the first
Registration Request of Du Pont shall be for not less than 20,000 Class A Shares
(or equivalent).

          (b)   Registration Expenses.  Du Pont shall bear the costs and
                --------------------- 
expenses incurred in connection with the registration of the sale or other
distribution of the Registrable Securities pursuant to the terms of this section
1.1 (or, if securities are included in any such registration for the account of
CEI or any other security holders, Du Pont shall bear its proportionate share of
such costs and expenses, except Du Pont shall pay any

                                       2

underwriting fees, discounts or commissions attributable to sales of Registrable
Securities by Du Pont and any "out-of-pocket" expenses of Du Pont, including Du
Pont's counsel's fees and expenses) including, without limitation, (i) all
filing fees with the Commission; (ii) fees and expenses of compliance with
securities or blue sky laws (including fees and disbursements of counsel in
connection with blue sky qualifications of the Registrable Securities, (iii)
printing expenses, (iv) the fees and expenses incurred in connection with the

of any comfort letters).

          (c)  Other Registration Provisions and Procedures.  Any registration 
               --------------------------------------------  
under this section 1.1 shall be subject to the following procedures:

          1.   As to any proposed offer or sale of Registrable Securities, such
               securities shall cease to be Registrable Securities where (a) a
               registration statement with respect to the sale of such
               securities shall have become effective under the Securities Act
               and such securities shall have been disposed of in accordance
               with such registration statement, or (b) such securities have
               been transferred or sold to any individual or entity other than
               Du Pont or any affiliate of Du Pont.

          2.   Upon any registration under section 1.1 of this Exhibit becoming
               effective, CEI will use its best efforts to keep such
               registration statement current for a period of 90 days or such
               shorter period which will terminate when all Registrable
               Securities covered by such registration statement have been sold.

          3.   A Registration Request shall not be deemed to have been made for
               purposes of the first sentence of section 1.1(a) hereof:

               (a)  if, after a registration statement has become effective,
                    such registration statement is interfered with by any stop
                    order, injunction or other order or requirement of the
                    Commission or other governmental authority for any reason
                    other than an act or omission of Du Pont;

                                       3
<PAGE>
 
              (b)   if the conditions to closing specified in any purchase
                    agreement or underwriting agreement entered into in
                    connection with such registration are not satisfied other
                    than by reason of some act or omission by Du Pont; or

              (c)   if CEI voluntarily takes any action that would result in Du
                    Pont not being able to sell such Registrable Securities
                    covered thereby; or

              (d)   if Du Pont notifies CEI in writing of Du Pont's intention
                    not to proceed with a registration prior to execution of an
                    underwriting agreement relating to that Registration
                    Request.

          4.   In connection with any offering of Registrable Securities
               pursuant to this Exhibit, CEI (a) will furnish to Du Pont and the
               underwriters such number of copies of any prospectus (including
               any preliminary prospectus) and prospectus supplement as Du Pont
               or such underwriters may reasonably request in order to effect
               the offering and sale of the Registrable Securities to be offered
               and sold, but only while CEI shall be required under the
               provisions hereof to cause the registration statement to remain
               current, and (b) take such action as shall be necessary to
               qualify the Registrable Securities covered by such registration
               under blue sky or other state securities laws for offer and sale
               as Du Pont or the underwriters shall request; provided, however,
                                                             --------  ------- 
               that CEI shall not be obligated to qualify as a foreign
               corporation to do business under the laws of any jurisdiction in
               which it shall not be then qualified or to file any general
               consent to service of process or to subject itself to taxation in
               any jurisdiction wherein it would not otherwise be subject to
               taxation but for the requirement of this paragraph.

          5.   The underwriters acting hereunder shall be selected by Du Pont
               with the prior written approval of Rheinbraun and CEI (which
               approval shall not be unreasonably withheld).  Any underwriting
               agreement made hereunder shall be subject to the prior written
               approval of Du Pont 

                                       4
<PAGE>
 
               and Rheinbraun (which approval shall not be unreasonably
               withheld).

          6.   In connection with any offering of Registrable Securities
               registered pursuant to this Agreement, CEI shall (a) furnish Du
               Pont, at CEI's expense, with certificates not containing legends
               affecting resales under the securities laws of the United States
               or any State representing ownership of the Registrable
               Securities, in such denominations as Du Pont shall request, which
               are sold pursuant to the prospectus contained in the registration
               statement.

          7.   In connection with CEI's obligations under section 1.1(a) hereof,
               CEI will:

               (a)  prepare and file with the SEC within 90 days after receipt
                    of a Registration Request with respect to such Registrable
                    Securities (except as otherwise permitted by section 1.1(a)
                    of the Agreement), a registration statement on any form for
                    which CEI then qualifies and which shall be appropriate to
                    effect the intended method of distribution and which form
                    shall be available for the sale of the Registrable
                    Securities in accordance with the intended method of
                    distribution thereof; provided, however, that the
                                          --------                   
                    registration statement, if other than on Form S-1, will
                    contain such additional information in compliance with
                    securities laws as the underwriters deem necessary or
                    appropriate for marketing purposes and which shall be
                    reasonable and customary, and use its best efforts to cause
                    such registration statement to become and remain effective;
                    and before filing a registration statement or prospectus or
                    any amendments or supplements thereto relating to a
                    registration pursuant to section 1.1(a) hereof, CEI will
                    furnish to Du Pont and counsel selected by Du Pont (and the
                    underwriters) copies of all such documents proposed to be
                    filed, and CEI will not file any registration statement to
                    which Rheinbraun or Du Pont or their respective counsel (or
                    the underwriters) shall reasonably object;

<PAGE>
 
               (b)  cooperate and assist in any filings required to be made with
                    a securities exchange or the National Association of
                    Securities Dealers, Inc.;

               (c)  cause the prospectus to be supplemented by any required
                    prospectus supplement, and as so supplemented to be filed
                    pursuant to the Securities Act;

               (d)  notify Du Pont promptly: (i) when the prospectus or any
                    prospectus supplement or post-effective amendment has been
                    filed, and, with respect to the registration statement or
                    any post-effective amendment, when the same has become
                    effective; (ii) of any request by the Commission for any
                    amendments or supplements to the registration statement or
                    the prospectus or for additional information; (iii) of the
                    issuance by the Commission of any stop order suspending the
                    effectiveness of the registration statement or the
                    initiation of any proceedings for that purpose; (iv) if, at
                    any time prior to the closing contemplated by an
                    underwriting agreement entered into in connection with such
                    registration statement, that the representations and
                    warranties of CEI contained therein cease to be true and
                    correct; (v) of the receipt by CEI of any notification with
                    respect to the suspension of the qualification of the
                    Registrable Securities for sale in any jurisdiction or the
                    initiation or threatening of any proceeding for such
                    purpose; and (vi) of the happening of any event which makes
                    any statement in the prospectus or any document incorporated
                    therein by reference untrue and which requires the making of
                    any changes in the registration statement, the prospectus or
                    any document incorporated therein by reference in order to
                    make the statements therein not misleading;

               (e)  make reasonable efforts to obtain the withdrawal of any
                    order suspending the effectiveness of the registration
                    statement;

                                       6
<PAGE>
 
               (f)  furnish to Du Pont, without charge, one copy of the
                    registration statement as declared effective by the
                    Commission and any post-effective amendment thereto,
                    including financial statements and schedules, all documents
                    incorporated therein by reference and all exhibits
                    (including those incorporated by reference);

               (g)  upon the occurrence of any event referred to in paragraph
                    7(d)(vi) of this section, prepare a supplement or post-
                    effective amendment to the registration statement, the
                    related prospectus or any document incorporated therein by
                    reference or file any other required document so that, as
                    thereafter delivered to purchasers of the Registrable
                    Securities, the prospectus will not contain an untrue
                    statement of a material fact or omit to state any material
                    fact necessary to make the statements therein not
                    misleading;

               (h)  use reasonable efforts to cause all Registrable Securities
                    covered by the registration statement to be listed on a
                    securities exchange if requested by Du Pont or the
                    underwriters;

               (i)  use reasonable efforts to obtain (i) for delivery at each
                    closing of the sale of Registrable Securities, opinions of
                    counsel to CEI and updates thereof addressed to the
                    underwriters, if any, of such sale covering the matters
                    customarily covered in opinions requested in underwritten

               (j)  participate and cause such members of its management as the

                    promotional meetings to the extent reasonably requested by
                    the underwriters; and

                    applicable law and rules and regulations of the Commission.

          1.2. Public Offering Indemnities.  In the event of any registered
               ---------------------------                                 
offering of Registrable Securities pursuant to section 1.1 hereof:

          (a)  CEI will indemnify and hold harmless, to the fullest extent
permitted by law, Du Pont, Rheinbraun, and any underwriter, as defined in the
Securities Act, and each person, if any, who controls Du Pont, Rheinbraun, or
such underwriter within the meaning of the Securities Act, from and against any
and all losses, damages, claims, liabilities, joint or several, reasonable costs
and expenses (including any amounts paid in any settlement effected with CEI's
consent) to which Du Pont, Rheinbraun, or any such underwriter or controlling
person may become subject under the Securities Act, state securities or blue sky
laws, common law or otherwise, insofar as such losses, damages, claims,
liabilities (or actions or proceedings in respect thereof), costs or expenses
arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in the registration statement or the
prospectus included therein, as amended or supplemented, or (ii) the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances in
which they are made, not misleading, and CEI will reimburse Du Pont, Rheinbraun,
any underwriter, and each such controlling person, promptly upon demand, for any
legal or any other expenses incurred by them in connection with investigating,
preparing to defend or defending against such loss, damage, claim, liability,
action or proceeding; provided, however, that CEI will not be liable in any such
                      --------  -------                                         
case to the extent that any such loss, damage, liability, cost or expense arises
out of or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission so made in conformity with information furnished by
Du Pont, Rheinbraun, such underwriter or such controlling persons, 

                                       8
<PAGE>
 
as the case may be, in writing specifically for use in the preparation thereof,
provided, further, that CEI will not be liable under the indemnity agreement of
- --------  -------
this section to Du Pont, Rheinbraun, or any underwriter (or controlling person
of any of them) with respect to any preliminary prospectus to the extent that
any such loss, damage, liability, cost or expense results from the fact that
Registrable Securities were sold by any such indemnitee to a person to whom
there was not sent or given, at or prior to the written confirmation of such
sale, a copy of the final prospectus as then amended or supplemented if CEI has
previously furnished copies thereof to Du Pont, Rheinbraun, such underwriter or
such controlling person as the case may be. Such indemnity shall remain in full
force and effect regardless of any investigation made by or on behalf of Du
Pont, Rheinbraun, any underwriter and shall survive the transfer of such
Registrable Securities by Du Pont.

          (b)  Du Pont shall indemnify and hold harmless Rheinbraun and CEI,
each director of Rheinbraun and CEI, each officer of CEI who signs such
registration statement, any underwriter, and each person, if any, who controls
CEI or Rheinbraun or such underwriter from and against any and all loss, damage,
liability, cost or expense to which Rheinbraun or CEI or any such controlling
person or any underwriter may become subject under the Securities Act or
otherwise, insofar as such losses, damages, liabilities, costs or expenses (i)
are caused by any untrue or alleged untrue statement of any material fact
contained in the registration statement or included prospectus, as amended or
supplemented, or (ii) arise out of or are based upon the omission or the alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was so made in conformity with written information furnished by
Du Pont to CEI for use therein.

          (c)  Rheinbraun shall indemnify and hold harmless Du Pont and CEI,
each director of Du Pont and CEI, each officer of CEI who signs such
registration statement, any underwriter, and each person, if any, who controls
CEI or Du Pont or such underwriter from and against any and all loss, damage,
liability, cost or expense to which Du Pont or CEI or any such controlling
person or any underwriter may become subject under the Securities Act or
otherwise, insofar as such losses, damages, liabilities, costs or expenses (i)
are caused by any untrue or alleged untrue statement of any material fact
contained in the registration statement or included prospectus, as amended or
supplemented, or

                                       9
<PAGE>
 
(ii) arise out of or are based upon the omission or the alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances in which they were made,
not misleading, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission was
so made in conformity with written information furnished by Rheinbraun to CEI
for use therein.

          (d)  Promptly after receipt by an indemnified party pursuant to the
provisions of subsection (a), (b), or (c) of this section of written notice of
the commencement of any action with respect to which a claim for indemnity may
be made pursuant to this section, such indemnified party will, if a claim
thereof is to be made against the indemnifying party pursuant to the provisions
of said subsection (a), (b), or (c) promptly notify in writing the indemnifying
party of the commencement thereof; but the omission to notify the indemnifying
party will not relieve it from any liability which it may have otherwise to any
indemnified party.  In case such action is brought against any indemnified party
and it notifies the indemnifying party of the commencement thereof, the
indemnifying party shall have the right to participate in, and, to the extent
that it may wish, jointly with any other indemnifying party similarly notified,
to assume the defense thereof; provided, that, if the defendants in any action
                               --------  ----                                 
include both the indemnified party and the indemnifying party and there is a
conflict of interest that would prevent counsel for the indemnifying party from
also representing the indemnified party, the indemnified parties shall have the
right to select one separate counsel to participate in the defense of such
action on behalf of all such indemnified parties.  After notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party pursuant to the provisions of said subsection (a), (b), or (c) for any
legal or other expense subsequently incurred by such indemnified party in
connection with the defense thereof, other than reasonable costs of
investigation, unless (i) the indemnified party shall have employed counsel in
accordance with the provision of the immediately preceding sentence or (ii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party.  No indemnifying party will
consent to entry of any judgment, or enter into any settlement with respect to a
claim, without the written consent of the indemnified party (which consent shall
not be unreasonably withheld) or unless such judgment or settlement includes as
an unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all 

                                      10
<PAGE>
 
liability in respect to such claim or litigation. No indemnified party shall
consent to entry of any judgment or enter into any settlement of any action the
defense of which has been assumed by an indemnifying party without the consent
of such indemnifying party, which consent shall not be unreasonably withheld.

          (e)  If recovery is not available under the foregoing indemnification
provisions or is insufficient to hold harmless an indemnified party in respect
of any losses, claims, liabilities, costs or expenses specifically covered by
the indemnification provisions set forth above for any reason other than as
specified in section 1.2(a), (b), or (c), the parties entitled to
indemnification by the terms thereof shall be entitled to contribution to
losses, claims, liabilities, costs and expenses as may be more fully set forth
in an underwriting agreement to be executed in connection with such
registration, except to the extent that contribution is not permitted under
section 11(f) of the Securities Act.  In determining the amount of contribution
to which the respective parties are entitled, there shall be considered the
relative benefits and faults and any other equitable considerations appropriate
under the circumstances provided in section 11(f) of the Securities Act.  No
person guilty of fraudulent misrepresentation (within the meaning of section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.  The contribution
provided for in this section shall survive, with respect to a holder of
Registrable Securities, the transfer of Registrable Securities by such holder,
and, with respect to a holder of Registrable Securities or CEI, shall remain in
full force and effect regardless of any investigation made by or on behalf of
any indemnified party.

public sale of equity securities of CEI (or securities convertible into or
exchangeable for such equity securities) during the seven days prior to and the
90 days after any underwritten registration pursuant to this Exhibit B has
become effective, or such longer period (not to exceed 180 days) as the
underwriter may reasonably request consistent with customary practice.

                             Amended Section 4.2.1
                             as of October 1, 1998
                             ---------------------
                                        

          4.2.1  During any period that members of the Du Pont Group and the
Rheinbraun Group shall be the sole shareholders of CEI, the provisions of this
paragraph 4.2.1 shall apply to any purported disposition of Shares by any such
shareholder.  Du Pont and Rheinbraun each guarantee that the obligations imposed
by this paragraph shall be duly performed by any shareholder that is a member,
respectively, of the Du Pont Group or the Rheinbraun Group.

          (a)  The Seller shall give written notice to the Offeree (the "Option
               Notice") of the terms and conditions upon which the Seller may
               desire to sell the Offered Shares to a third party or parties.

          (b)  The Offeree shall, within 30 days after receipt of the Option
               Notice, give written notice to the Seller whether it elects to
               purchase not less than all the Offered Shares on the terms and
               conditions set forth in the Option Notice.

          (c)  If the Offeree shall elect to purchase the Offered Shares, the
               Offeree's notice of election shall 
<PAGE>
 
               specify a date, not later than 30 days after the receipt by the
               parties of all necessary governmental or other regulatory
               approvals for such purchase, or, if no such approvals are
               required, not later than 60 days after the Offeree's receipt of
               the Option Notice, for the closing of such purchase. The giving
               of a notice in such form shall bind the Offeree to purchase, and
               the Seller to sell and transfer, on the date of the closing so
               specified, the Offered Shares on the terms and conditions stated
               in the Option Notice, and shall also bind the Seller and Offeree
               to pursue diligently the obtaining of all such governmental and
               regulatory approvals. In any such sale the Seller shall be deemed
               to have warranted to the Offeree that the Seller has good and
               unencumbered title to the Offered Shares.

          (d)  If the Offeree, by notice to the Seller, shall elect not to
               exercise its right to purchase the Offered Shares, or if 30 days
               shall have elapsed from the date of receipt of the Option Notice
               by the Offeree without such election having been notified to the
               Seller, then the Seller may sell and transfer the Offered Shares
               to any third party or parties in a single transaction if such
               sale 
<PAGE>
 
               shall be on terms and conditions no less favorable to Seller than
               the terms and conditions stated in the Option Notice; provided,
                                                                     --------
               that the following condition shall have been satisfied: the
               Seller shall have given written notice (the "Identification
               Notice") to the Offeree of the identity of such third party or
               parties together with a copy of (i) a letter of intent executed
               by all parties (but only if such letter of intent has been
               publicly disclosed), or, alternatively, (ii) a definitive,
               integrated agreement of sale executed by all parties (which
               agreement or letter of intent, as the case may be, shall include
               provision for a closing to be consummated not sooner than the
               40th day following the date of delivery to the Offeree of the
               Identification Notice subject to the terms of this subparagraph),
               and the Offeree shall have the option, exercisable by written
               notice delivered to the Seller prior to the 30th day following
               the date of delivery to the Offeree of the Identification Notice,
               to purchase the Offered Shares on the terms and conditions
               specified in such letter of intent or agreement of sale, as the
               case may be, except that the amount payable by the Offeree shall
               be 104% of the
<PAGE>
 
               economic value of the cash, stock and any other property
               specified in such letter of intent or agreement of sale as the
               price of the Offered Shares. If the Offeree shall exercise such
               option, the Offeree shall be bound to purchase, and the Seller to
               sell and transfer to the Offeree, the Offered Shares on a closing
               date not later than the 30th day following the receipt of all
               necessary governmental and regulatory approvals, but if no such
               approvals are required, not later than the 60th day following the
               date of delivery of the Identification Notice. The exercise of
               such option by the Offeree shall bind the Seller and Offeree to
               pursue diligently the obtaining of all such necessary
               governmental and regulatory approvals. In any such sale the
               Seller shall be deemed to have warranted to the Offeree that the
               Seller has good and unencumbered title to the Offered Shares.

          (e)  If the Seller shall not have completed the transfer of all of the
               Shares referred to in the Option Notice to a third party or
               parties in a single transaction on or before the first
               anniversary of the date of the Option Notice, the restrictions on
               transfer imposed by this Article 
<PAGE>
 
               shall again apply to any proposed transfer of such Shares.

          CONSULTING AGREEMENT dated as of February 1, 1999, between CONSOL
     INC., a Delaware corporation (hereinafter the "Corporation") and B. R.
     Brown (hereinafter "Mr. Brown").

     Mr. Brown is Chairman of the Board of Directors of the Corporation. He has
been employed by the Corporation under an agreement dated December 9, 1996, as
extended until June 30, 1998 (by a written agreement dated February 26, 1998),
and as extended until January 31, 1999 (by informal agreement). He will retire
as Chairman of the Board effective January 31, 1999. In view of his long
experience with the Corporation and his knowledge of its affairs, the
Corporation desires to have him available to act as a consultant to the
President of the Corporation during the period February 1, 1999, to January 31,
2000, on the terms and conditions hereinafter set forth.

     Accordingly, the parties hereto hereby agree as follows:

     1.  Period of Consultancy. During the period February 1, 1999, to January
         ---------------------
31, 2000, Mr. Brown shall serve the Corporation in the capacity of general
consultant. To that end he shall be available for consultation and advice as and
when the President of the Corporation may reasonably require. Mr. Brown shall
not, however, be required to attend regularly at any


     
<PAGE>
 
business office of the Corporation or to live at any specified place for any
stated period or periods of time. Insofar as it shall be practicable from a
business point of view, the Corporation shall consider the reasonable
convenience of Mr. Brown in timing its requests, and the failure or inability of
Mr. Brown by reason of illness or cause beyond his control to respond to such
requests shall not be deemed to constitute a default on his part in the
performance of his obligations under this Agreement. Mr. Brown agrees to render
his services in such manner and under such circumstances as shall be in the best
interests of the Corporation and consistent with its general policies. The
services which Mr. Brown shall render to the Corporation under this Agreement
shall be rendered in the capacity of an independent contractor.

          2.  Compensation. As compensation for his services under this
              ------------
Agreement, the Corporation will pay to Mr. Brown $360,000 per year, payable in
equal monthly installments, in the period February 1, 1999, to January 31, 2000;
provided, that, if in any month Mr. Brown shall actually be engaged in work for
- --------
the Corporation for more than six days (whether or not consecutive), the
Corporation will pay to him a consultation fee of $5,000 for each such
additional day (or substantial part thereof) in such month that Mr. Brown shall
actually be engaged in work for the Corporation. In said period the Corporation
will reimburse Mr. Brown for any out-of-pocket disbursements which he shall

               ----------- 

          As used in this Agreement, the following terms shall have the meanings
given below, respectively:

          "Affiliate" shall mean CEI, CI, and any corporation controlled by CEI
or CI, or both of them, directly or indirectly.

          "Term" shall mean the period commencing January 1, 1998, and ending on

and President of both Corporations.  You hereby agree to accept such employment
and such positions.

          (b) During the Term you will hold identical offices and directorships
in both CEI and CI, and you will serve those corporations accordingly.  You
hereby confirm that you have been provided with a copy of the By-laws of each of

          (c) During the Term, you will devote the necessary business time and
attention, and use your best efforts consistent with your current skills,

Affiliates.  Without the prior written consent of the Boards of each of CEI and

for disability pension under the CI Employee Retirement Plan (the "ERP"), (b)
                                                                          ---

be paid to you (or your estate, in event of your death) until the end of the
Term, plus a one-time payment in an amount equal to any incentive compensation
received in the preceding twelve months.  In such event, you (or your estate, in
the event of your death) shall also he entitled for purposes of the ERP to
receive service credit for the remainder of the Term.

          (c) For purposes of this Agreement, "cause" shall mean (i) gross
negligence detrimental to CEI, CI or their Affiliates, or willful misconduct;
(ii) the commission of a felony or other crime involving moral turpitude; or
(iii) such personal misconduct by you as shall bring CEI, CI or their Affiliates
into disrepute.  In the event of termination for cause, your compensation and
benefits shall cease and terminate at the end of the month in which the notice
of termination was given.

          4.  Compensation.
              ------------

such additional amounts as may be determined from time to time by the Board of
CI in its sole discretion.  Any increase in base salary approved by the Board of
CI will not be subsequently reduced or eliminated without your consent.

service credit, representing your years of employment at PacifiCorp and its
affiliated companies ("PacifiCorp").  It is agreed, however, that there shall be
deducted from the amount of any benefit payable to you under the ERP, an amount
equal to the aggregate amount of any benefits payable to you pursuant to the any
retirement or similar plans of PacifiCorp.

confidential information shall not include any information which (i) is known
                                                                 ---         
generally to the public other than as a result of unauthorized disclosure by
you, (ii) becomes available to you on a non-confidential basis from a source
     ----                                                                   
other than CEI, CI or any of their Affiliates, or (iii) was available to you on
                                                  -----                        
an non-confidential basis prior to its disclosure to you by CEI, CI or any of
their Affiliates.

          (b) You agree that, for a period of twelve (12) months after the
termination of your engagement hereunder, you will not directly or indirectly
participate in any attempt to hire or solicit the employment of any person who
was at such termination, an employee, officer or director of CEI, CI or any of
their Affiliates.

          (c) You agree that so long as you are entitled to receive compensation

                         --------

          6.  Binding Agreement.
              ----------------- 

          The provisions of this Agreement shall be binding on you and CEI, CI
and their successors and assigns.  You hereby acknowledge that the undertakings
hereunder are unique to you, and any purported assignment by you without CEI's

          7.  Miscellaneous.

to be invalid,
<PAGE>
 
Mr. J. Brett Harvey
December 11, 1997
Page 5


illegal or unenforceable in any respect, it shall not affect any other provision
hereof, and this Agreement shall be construed as if such invalid, illegal or
unenforceable provision had never been contained herein.  If any provision
hereof shall for any reason be held to be excessively broad as to duration,
geographical scope, activity or subject, it shall be construed by limiting or
reducing it to the extent necessary to render it enforceable under then current
law.  This Agreement shall supersede all prior understanding between you and CEI
and CI as to the terms of your employment.  No waiver by any party of the breach
by the other of any provision hereof shall be deemed a waiver of any later or
other breach hereof, or a waiver of any other provision hereof.  This Agreement
sets forth all the terms and understandings between the parties with respect to
the subject matter hereof and may not be waived, amended, discharged or
terminated orally or by any course of dealing by the parties, but only by an
instrument in writing signed by the party against whom any waiver, change,
discharge or termination is sought to be enforced.
