                               ITEM 1.  BUSINESS

     Zeigler Coal Holding Company ("Zeigler" or the "Company"), through its
subsidiaries, is one of the largest coal producers in the United States.  The
Company currently operates, through its subsidiaries, seven active underground
and surface coal mining complexes located in five states, two east coast
transloading terminals, a power marketing business, and other energy-related
businesses.

     Coal operations accounted for 75% of the Company's total revenues and 125%
of operating earnings in 1997.  The Company produces primarily steam coal, with
sales to electric utilities accounting for approximately 90% of its 1997
revenues from coal sales.  In 1997, approximately 89% of the Company's revenues
from coal sales resulted from long-term supply contracts, most of which call
for prices that exceed the price at which such coal could be sold in the spot
market.  At December 31, 1997, the Company owned or held through leases
approximately 1.2 billion tons of economically recoverable coal reserves,
including .9 billion tons of low-sulfur and compliance coal.

HISTORY

     In January 1985, the Company purchased Zeigler Coal Company from Houston
Natural Gas Corporation.  At that time, Zeigler Coal Company's mines and
principal reserves were located in southern and central Illinois.  In July
1990, the Company acquired all of the common stock of Old Ben Coal Company from
BP America Inc.  At the time of the acquisition, Old Ben Coal Company had mines
and reserves in Illinois, Indiana and West Virginia.  In November 1992, Zeigler
Coal Company was merged into Old Ben Coal Company.  Also in November 1992, the
Company acquired all of the stock of Shell Mining Company.  At the time of the
acquisition, Shell Mining Company controlled mines and reserves in 10 states,
two transloading terminals located on the east coast, Encoal Corporation, and
other coal-related assets.

     In 1996, the Company established EnerZ Corporation, the Company's energy
trading and marketing subsidiary, which received approval from the Federal
Energy Regulatory Commission ("FERC") in the fourth quarter of 1996 for status
as a wholesale power marketer, and initiated trading activities in the first
quarter of 1997.  Another subsidiary, Zenergy, Inc., owns a 30% interest in
Louisiana Generating LLC, which has made an offer to purchase out of bankruptcy
the non-nuclear assets of Cajun Electric Power Cooperative, Inc. of Baton
Rouge, Louisiana.

     On December 3, 1997, the Company announced that it was retaining an
investment banking firm to explore various strategic alternatives to maximize
value for shareholders, including the possible sale of the entire Company.  In
connection therewith, the Board of Directors adopted a change-in-control
severance plan and retention bonus plan for all salaried employees as well as
special incentives for certain key employees.  The Company has since retained
the investment banking firm Credit Suisse First Boston and prepared materials
for interested parties.

COAL OPERATIONS

     The Company views each of its mining complexes as a separate resource, with
distinct coal qualities, reserve lives, transportation alternatives, and
production and cost characteristics.  While spot market sales may justify
continued operations of a particular mine, the Company generally seeks long-term
coal supply contracts for each mine's output.  Due to the Clean Air Act
Amendments of 1990 (Clean Air Act), the Company expects to expand the sale of
its low-sulfur coal resources and to focus its higher-sulfur coal sales effort
on those utilities which have installed scrubbers or have other capabilities to
meet their compliance objectives with such coal.  The Company intends to develop
its reserves and open mines as satisfactory long-term commitments for the coal
are obtained.

     The Company's active coal operations include the following:

     Bluegrass Coal Development Company - Bluegrass includes Evergreen Mining
Company in West Virginia, Pike County Coal Corporation in Kentucky, R. & F.
Coal Company in Ohio, and Turris Coal Company in Illinois.

     Mountaineer Coal Development Company - Mountaineer consists of Marrowbone
Development Company in West Virginia.

     Old Ben Coal Company - Old Ben consists of Old Ben Mine #11 in Illinois.

     Triton Coal Company - Triton includes the Buckskin Mine and the North
Rochelle Mine (under development) in Wyoming.

     Sales and Marketing

     Franklin Coal Sales Company ("Franklin") provides sales and marketing 
support to all Zeigler companies.  Sales activities are organized for the
different coal groups, with a sales team responsible for all accounts within
each group.  The sales teams are responsible for submitting bids,
negotiating sales terms and conditions, and for providing other services as
customers require. Franklin provides a limited range of services to other
Zeigler companies, including coal purchasing for blending and market research. 
Franklin forecasts future demand for various coal types and works with
employees of the operating companies to determine the optimal production of
coal.  Franklin also assists in the negotiation and maintenance of coal sales
contracts, helps customers in securing transportation agreements, and monitors
compliance with contract terms and delivery schedules.

     Competition and Pricing

     Zeigler competes with other large producers and hundreds of small
producers in the U.S. and abroad.  The principal customers for Zeigler coal
production are electric utilities, with coal qualities, price, location,
transportation costs, and reliability being the most important factors upon
which the Company competes with other coal producers.  Most of Zeigler's
production is sold under long-term coal supply contracts which are the result
of competitive bidding and extensive negotiations.

     The markets in which Zeigler sells its coal are affected by numerous
factors beyond Zeigler's control. Continued demand for Zeigler's coal and the
prices that Zeigler will be able to obtain will depend primarily on coal
consumption patterns of the domestic electric utility industry which in turn
are affected by the demand for electricity, environmental and other
governmental regulations and orders, technological developments, and the
availability and price of competing coal and alternative fuel supply sources
such as natural gas or oil.




                                      2

     Transportation is an important factor in coal marketing because a
significant portion of a customer's delivered cost of coal is attributable to
transportation.  Generally, transportation costs from the mine to the place of
use (e.g., the customer's power plant) are incurred directly by the customer.
The availability and cost of transportation affects the marketability of coal.

     In 1997, approximately 82% of Zeigler's sales tonnage left the mine site
by rail with the balance by truck.  Transportation by inland waterway barges,
at a lower cost than by railroad, is available to many of Zeigler's mines in
the Midwest and West Virginia, and approximately 24% of the Company's coal
shipments are moved by barge at some point during shipping.  Most of the
Company's mines are served by a single railroad, although some mines are served
by multiple railroads.  The Staggers Rail Act of 1980 limited the Interstate
Commerce Commission's regulation of the railroad industry and increased the
freedom of railroads to set their own rates and enter into transportation
contracts.  The practices of and rates set by the railroad servicing a mine may
affect, either adversely or favorably, Zeigler's marketing efforts with respect
to coal produced from that mine.

     North Rochelle Development

     The Company announced in February 1996 the full-scale development of
Triton Coal Company's North Rochelle mine in the southern Powder River Basin.
Since that time, Triton has been primarily engaged in moving dragline
overburden removal equipment to the site, production of diligence tonnage,
permitting, and engineering and construction work.  At this time, Triton
estimates full production at North Rochelle to begin in the first quarter of
1999.  The estimated total cost to develop North Rochelle is approximately
$100.0 million.

     Long-term Coal Supply Contracts

     Zeigler's subsidiaries have entered into various long-term coal supply
contracts with its electric utility customers.  Customers enter into long-term
contracts for coal principally to secure a reliable source of supply at a
predictable price.  Zeigler enters into such contracts to provide the stable
sources of revenues required to support the large expenditures needed to open,
expand or maintain a mine to service the contract.  The Company's major
long-term contracts have remaining terms ranging from one to 18 years.  The
loss of certain long-term contracts could have a material adverse effect on
Zeigler's operations and business.  The following table sets forth information
regarding the Company's long-term coal supply contracts which, at December 31,
1997, had remaining terms of one or more years.

(1)  Reflects stated term of contract and does not assume the exercise by the
     Company of unilateral options to extend.  The  contract reopeners and
     other provisions of certain contracts may make the specified term of a
     long-term contract less meaningful.

(2)  Earliest estimated expiration date.  Actual date will vary with life of
     the units used by the customer.  See Item 8., "Financial Statements and
     Supplementary Data," Note 16, below.

(3)  The contract contains a 15 year first-right-of-refusal extension
     provision in favor of Triton.  In an effort to assist its customer in
     meeting its Phase II (Clean Air Act) requirements, Zeigler converted the
     extension provision into a firm contract for North Rochelle coal,
     contingent on opening the North Rochelle mine.  The contract provides the
     flexibility for deliveries from Buckskin, under certain circumstances, if
     North Rochelle is not yet in commercial production by 1999.  The Company
     estimates that full production at North Rochelle will begin in the first
     quarter of 1999.

(4)  Shipments will commence upon the opening of the North Rochelle mine for
     1.0 million tons per year for the first year (1999) and 4.0 million tons
     per year thereafter until 2011.


(5)  Shipments will commence in 1998 for a total of 6.1 million tons over the
     contract period.

     The terms of long-term coal supply contracts are the result of both
bidding procedures and extensive negotiations with the customer.  As a result,
the terms of such contracts vary significantly in many respects, including
price adjustment features, price reopener terms, coal qualities, quantity,
flexibility and adjustments, Zeigler's ability to provide coal from various
sources, environmental restraints, force majeure provisions, termination
provisions, extension options and assignability.

     A majority of Zeigler's long-term coal supply contracts contain price
reopener provisions under which the contract price can be periodically adjusted
upward or downward based on changes in the market price of coal since the
contract was executed or the last application of a price reopener provision.
The price reopener provision may specify an index or other market pricing
mechanism on which a new contract price is to be based.  Frequently, bid
solicitations are sent by the customer to other suppliers to use in
establishing a new price or for the purpose of establishing a
first-right-of-refusal.  In some cases, the parties may seek an arbitration or
other dispute resolution mechanism if the parties do not agree.  In other
cases, the contract may provide for termination if the parties do not agree.
Some price reopener provisions contain limitations on the amount of price
change that can result from application of the provision.

     Contract prices under long-term coal supply agreements frequently vary
from the price at which a customer is able to acquire and take delivery of coal
of similar quality in the spot market.  The delivered cost to the customer in
the spot market will depend on the quality of the available coal, the
competitive climate in the market from which deliveries can economically be
made, the availability and cost of transportation to the customer's facility
and other factors.  All such factors vary from time to time.

     Some of these contracts contain hardship or gross inequities clauses.
From time to time, customers have asserted the right to use these clauses as
price reopener clauses in an attempt to reduce the prices under long-term
contracts.  The Company has rejected these assertions, but there can be no
assurance that customers will not assert such clauses in the future in an
attempt to obtain favorable price concessions.  In most cases, market
conditions do not constitute gross inequities or hardship.

     Zeigler's long-term coal supply contracts specify qualities for the coal
to be delivered relating to the coal's BTU, sulfur and moisture content,
grindability, and other factors. Generally, coal quality specifications are
based on the reserves from which the coal is intended to be mined, and the
contract may specify the reserves from which the coal is to be mined.

     Zeigler's long-term coal supply contracts contain force majeure provisions
allowing suspension of performance by Zeigler or the customer to the extent
necessary during the duration of certain events beyond the control of the
affected party, including labor disputes, natural disasters, casualties,
government impositions, transportation disruptions, and similar events.
Certain contracts may terminate upon continuation of an event of force majeure
for an extended period of time (generally six months or more).  Deficiencies in
deliveries of coal which are caused by force majeure may or may not be made up,
depending upon the specific language of the contract or needs of the parties.

     From time to time during the term of the various long-term contracts,
Zeigler is involved in disputes relating to, among other things, coal quality,
pricing and quantity.  While customer disputes, if unresolved, could result in
termination or cancellation of the contract involved, Zeigler's experience has
been that curative and/or dispute resolution measures decrease the likelihood
of termination or cancellation.  In addition, Zeigler's development of
long-term business relationships with many of its customers has generally
permitted it to resolve business disputes in a mutually acceptable manner.
Nonetheless, Zeigler has from time to time been involved in arbitration and
other legal proceedings regarding its long-term contracts and there can be no
assurance that existing and future disputes can be resolved in a mutually
satisfactory manner.  The Company believes that in recent years the potential
deregulation of electric utilities and reduced spot market prices for coal have
caused some customers to become more aggressive in seeking to reduce, modify,
or terminate their obligations under their long-term contracts.

     The operating profit margins realized by Zeigler under its long-term coal
supply contracts depend on a variety of factors, vary from contract to
contract, and will fluctuate during the contract term, depending on contract
provisions, Zeigler's production cost, and other factors.  Termination or
suspension of deliveries under a high-priced contract could have an adverse
effect on earnings and operating cash flow disproportionate to the percentage
of production represented by the tonnage delivered under such contract.

     From time to time the Company discusses possible modifications to
long-term contracts with its customers, with a view toward responding to
concerns (including price and quality issues) raised by its customers while
preserving or enhancing the value of the contract to the Company.  In 1996, the
Company worked closely with several significant customers to reduce contract
risk, increase contract tonnage, and give Zeigler the flexibility to better
operate its mines in a cost effective manner as well as help customers meet
their own needs.  Elements of a contract that can be renegotiated include
sourcing and geographic flexibility, quality flexibility, increased volume, and
multi-tier pricing.   The Carolina Power & Light Company ("CP&L") contracts
described below were renegotiated in 1996 to accomplish one or more of those
elements.

     The following discussion contains a brief description of long-term
contracts relating to customers that accounted for more than 10% of Zeigler's
consolidated 1997 revenues from coal sales.  Each of these contracts calls for
coal prices that exceed the current spot price for coal sold in their
respective markets.  The six contracts, four long-term contracts with CP&L and
two long-term contracts with Georgia Power Company, collectively accounted for
approximately 45% of revenues from coal sales and more than 83% of the
Company's operating income in 1997.

     Carolina Power & Light Company - CP&L has four long-term contracts to      
     purchase coal from subsidiaries of the Company during 1998.  One contract
     provides for 2.8 million tons annually from the Marrowbone mining complex
     through 2006. The second contract, also from Marrowbone, provides for a
     total of 6.1 million tons over the contract period which commences in 1998 
     and expires 2006.  Both contracts have fixed price increases each year. The
     third agreement, which expires in December 2004, provides for the
     purchase of 1.5 million tons of coal annually with fixed quarterly tonnage
     increases. Currently, coal required to fulfill this contract is being
     purchased from outside suppliers.  A fourth contract calls for 0.5 million
     tons annually from Pike County or other CSX sources expiring in 2004. 
     This contract price is adjusted by a published index.  During 1997 and
     1996, sales to CP&L under these contracts accounted for approximately 29%
     and 18%, respectively, of Zeigler's consolidated revenues from coal sales.

     Georgia Power Company - Georgia Power Company has two long-term contracts  
     with subsidiaries of the Company.  One contract requires the purchase of
     1.5 million tons annually from Marrowbone.  This agreement expires in
     December 2008 with an option to extend for five years with the mutual
     consent of both parties.  The price adjusts to reflect changes in industry
     labor costs, quarterly changes in indices, and any changes in governmental
     impositions resulting from new or amended laws, rules and regulations
     levied upon the production, preparation or sale of coal.  The contract has
     a partial price reopener in July 1999 and every five years thereafter. 
     Georgia Power also has a long-term contract, which expires in December
     2010, to purchase 1.0 million tons annually from Pike County.  The price
     adjusts to reflect changes in industry labor costs and quarterly indices
     and may be reopened every five years.  The next reopener will be January
     2001.  During 1997 and 1996, sales to Georgia Power under these contracts
     and short-term arrangements accounted for approximately 16% and 14%,
     respectively, of Zeigler's consolidated revenues from coal sales.

     Coal Reserves and Other Properties

     The Company controls coal reserves in 10 states which contain substantial
amounts of coal of varying qualities.  Reserve estimates are prepared by the
Company's engineers and geologists and reviewed periodically to reflect data
received and developments affecting the reserves. Accordingly, reserve
estimates will change from time to time reflecting mining activities, analysis
of new engineering and geological data, changes in reserve holdings,
modification of mining plans, or mining methods and other factors.

     The following table summarizes the Company's coal reserves as of December
31, 1997. Information in the table, including the classification of reserves as
"Economic," is based on estimates by Company personnel.  As used in the table,
the following terms are defined as follows: "Assigned reserves" refers to
reserves legally recoverable generally through existing facilities using
current mining technology; "Economic" means that the reserve is recoverable
using current mining technology at costs estimated to be similar to those
incurred by currently operating mines producing similar quality coal;
"Unassigned reserves" refers to reserves legally recoverable using current
mining technology but which would require substantial capital investment for
facilities to enable recovery of the coal.  In addition to the reserves
reflected in the table, the Company owns or holds through leases approximately
870.3 million tons of coal deposits which are minable using current mining
technology but the costs of mining such coal may cause recovery to not be
commercially viable under current economic conditions or require further
investigation and evaluation to determine whether recovery is commercially
viable.

(1)  "Measured" reserves are those with the highest degree of geologic
     assurance.  Coal quantities are computed from bed thickness measurements
     in core holes, mine workings, and bed outcrops of prospect trenches.  The
     measurement sites are so closely spaced that coal bed continuity, geometry
     and minability are well established.   Generally, coal that lies within
     1/4 mile of a reliable point of coal thickness measurement is considered
     in the measured class.

(2)  "Indicated" reserves are those with a moderate degree of geologic
     assurance.  The assurance, although lower than for proven reserves, is
     high enough to assume continuity between points of measurement.  Coal that
     lies between 1/4 and 3/4 mile from a point of coal thickness measurement
     is considered in the indicated class.

(3)  The percentage of sulfur content is not necessarily indicative of the
     suitability of the coal for consumption in compliance with applicable air
     quality laws.  Such suitability is dependent upon a number of other
     factors, including other coal characteristics (such as BTU content), the
     emission control technology used or to be used at the power station, and
     specific emission limitations applicable to that station.  Current
     estimates of coal reserves owned or leased by the Company that would be
     considered "compliance" (coal which, when burned, emits less than 1.2
     pounds of sulfur dioxide per million BTU) coal are 0.9 billion tons.  In
     addition, the Company estimates that it has 0.3 billion tons of reserves
     which, when burned, would emit less than 2.0 pounds of sulfur dioxide per
     million BTU.

(4)  54.8 million tons of reserves previously shown as assigned at Marrowbone
     have been reclassified as unassigned to reflect the legal ownership of
     those reserves.

     Of the total 1,192.7 million tons of economic reserves shown above,
approximately 15.0% are owned by Zeigler or its subsidiaries, approximately
18.3% are leased from private parties, and approximately 66.7% are leased from
the federal government.  Of the remaining 870.3 million tons of
non-economically recoverable coal deposits, approximately 66.4% are owned by
Zeigler or its subsidiaries, approximately 32.1% are leased from private
parties, and approximately 1.5% are leased from state governments.

     The private leases generally have terms of between 10 and 20 years,
although they generally allow Zeigler the right to renew the lease for a stated
period or to maintain the lease in force until the exhaustion
of minable and merchantable coal.  These leases provide for royalties to be
paid to the lessor either as a fixed amount per ton or as a percentage of the
sales price.  Many leases also require payment of a lease bonus or minimum
royalties, payable either at the time of the execution of the lease or in
periodic installments.  In most cases, the minimum royalty payments are applied
to reduce future production royalties.  The loss of certain leases could
adversely affect Zeigler's ability to develop the related mine.

     Zeigler holds four federal coal leases which are administered by the
United States Department of the Interior pursuant to the Federal Coal Leasing
Amendments Act of 1976.  These leases cover the Company's principal reserves in
Wyoming.  Each of these leases continues for an indefinite term provided there
is diligent development of the lease and continued operation of the related
mine or mines.  The Bureau of Land Management ("BLM") has asserted the right to
adjust the terms and conditions of these leases, including rents and royalties,
after the first 20 years of their life and at 10-year intervals thereafter.
Annual rents under the Company's BLM leases are now generally $3 per acre.
Production royalties on BLM leases are 12.5 percent of the gross proceeds of
coal mined and sold.

     Consistent with industry practices, the Company conducts limited
investigations of title to its coal properties prior to leasing.  The title of
the lessors or grantors and the boundaries of the Company's leased properties
are not completely verified until such time as the Company prepares to mine
such reserves.  If defects in title or boundaries of undeveloped reserves arise
in the future, the Company's control of and right to mine such reserves could
be adversely affected.


  NONCOAL OPERATIONS

     The Company's noncoal operations primarily consist of EnerZ, the Encoal
clean coal demonstration plant, Zeigler Environmental Services Company, two
east coast transloading terminals, and Zenergy, Inc.

     EnerZ Corporation, located in New York, New York, is the Company's energy
trading and marketing subsidiary.  The Company's eight professional staff
members participate in the wholesale electric power market, and in both bulk
wholesale and retail gas marketing.  Approximately 80% of the 1997 revenues
were generated from electricity transactions with the remainder attributable to
natural gas trading.

     Encoal Corporation owns a pilot plant at the Buckskin Mine in Wyoming
which was constructed in cooperation with the Department of Energy ("DOE") as 
part of the Clean Coal Technology Program, a DOE program designed to develop
new technologies for producing and using clean coal.  The demonstration plant
was idled in September 1997.  

     Zeigler Environmental Services Company, located in Fairview Heights,
Illinois, is the Company's construction management and reclamation services
subsidiary.

     Pier IX, located on 66 acres in Newport News, Virginia, is served by the
CSX railroad and deals primarily with coal and cement. Pier IX has an annual
throughput capacity of 12.0 million tons per year.

     Shipyard River Coal Terminal, in Charleston, South Carolina, is located on
50 acres of land at the mouth of the Port of Charleston.  The terminal accesses
both rail and water transportation and handles liquid, granular, and bulk
materials including coal, fertilizers, aggregates, asphalt and other industrial
minerals.  Shipyard has an annual throughput capacity of 2.5 million tons per
year and is served by the CSX and Norfolk Southern railroads.

     Zenergy, Inc., owns a 30% interest in Louisiana Generating LLC
("Generating"), which has made an offer of $1.2 billion to purchase out   of
bankruptcy the non-nuclear assets (the "Cajun Assets") of Cajun Electric Power
Cooperative, Inc. of Baton Rouge, Louisiana.  This proposal was named the lead
proposal by Cajun's court-appointed bankruptcy trustee.  The trustee filed a
plan of reorganization that incorporates Generating's proposal, including a
definitive purchase agreement (the "Purchase Agreement") containing bankruptcy
court-approved buyer protection provisions.

     Cajun's non-nuclear assets include 1,463 megawatts of coal burning
capacity and 220 megawatts of gas-burning capacity, along with related
operating facilities such as a load control center.  Cajun supplies about 80%
of the power to the rural Louisiana markets and is currently operating at about
60% capacity.  Cajun filed for bankruptcy protection in December 1994.


                                      9

<PAGE>   12


     The consummation of Generating's acquisition of the Cajun Assets is
subject to a number of conditions, including, without limitation, the entering
of a final and non-appealable order by the United States Bankruptcy Court for
the Middle District of Louisiana (the "Bankruptcy Court") confirming the
trustee's plan of reorganization that incorporates the terms and conditions of
the Purchase Agreement, the receipt of all regulatory approvals, and other
conditions customary for transactions such as the acquisition of the Cajun
Assets.  Two other competing reorganization plans for Cajun have been filed
with the Bankruptcy Court.  Because of the uncertainty as to whether or when
the Bankruptcy Court will confirm the trustee's plan of reorganization
(especially in light of the competing reorganization plans and competitive
bidding nature of the bankruptcy proceeding) and as to whether all of the
conditions to consummating the acquisition of the Cajun Assets can be
satisfied, there can be no assurance that Generating's acquisition of the Cajun
Assets will be consummated upon the current terms and provisions of the
Purchase Agreement or any other terms. On March 18, 1998, Generating submitted
its final proposal for the acquisition of the Cajun Assets for a purchase price
of approximately $1.2 billion.  Generating's purchase price exceeds both of the
other competing bids for the acquisition of the Cajun Assets.  After March 18,
1998, none of the proposals for the acquisition of the Cajun Assets may be
altered. The current Bankruptcy Court confirmation hearing schedule calls for 
final briefs to be submitted by May 26, 1998, and for a decision to be rendered
shortly thereafter.

     Under the existing agreement regarding Cajun, Zenergy, Inc., Southern
Energy-Cajun, Inc., and NRG Energy, Inc., respectively, own 30%, 40%, and 30%
of the ownership interests in Generating, and would each contribute their pro
rata share of the capital required by Generating to consummate the acquisition
of, and operate, the Cajun Assets.  The Company currently estimates that, if
Generating is successful in its bid to acquire the Cajun Assets, Zenergy's
capital investment in Generating will be approximately $80 million.  The
Company is in the process of developing financing alternatives to fund its
investment in Generating, but presently does not have any commitments with
respect to funding such investment.

     Corporate Headquarters - The Company owns a 44,000 square-foot, two-story
office building in Fairview Heights, Illinois, which serves as Zeigler Coal
Holding Company's executive offices and headquarters for several of the
Company's noncoal subsidiaries.  Administrative offices for Mountaineer Coal
Development Company, Bluegrass Coal Development Company, and Triton Coal
Company are held under leases in Charleston, West Virginia; Lexington,
Kentucky; and Gillette, Wyoming, respectively.

EMPLOYEE AND LABOR RELATIONS

     As of December 31, 1997, Zeigler and its subsidiaries employed a total of
2,022 persons, of which approximately 651 were represented by the UMWA and
covered by the terms and conditions of the National Bituminous Coal Wage
Agreement ("NBCWA").  The current NBCWA expires on December 31, 2002.

     Current UMWA Contract

     Old Ben Coal Company is a member of the Bituminous Coal operators
Association ("BCOA") which recently entered into a new five year collective
bargaining agreement with the United Mine Workers of America ("UMWA") effective
January 1, 1998.  The new agreement provides for wage and pension increases for
employees but also provides for greater flexibility in scheduling work.  There
are no reopener provisions for the new agreement.

     Although Marrowbone Development Company is not a member of the BCOA, it
recently agreed to become bound by the terms and conditions of the 1998
BCOA/UMWA agreement.

     Apart from work stoppages which may occur upon termination of a collective
bargaining agreement, Zeigler Companies may from time to time be subject to
certain unauthorized work stoppages or wildcat strikes.  Typically, these
events are isolated, short in duration and localized.

     Coal Industry Retiree Health Benefit Act of 1992

     The Coal Industry Retiree Health Benefit Act of 1992 (the "Health Benefits
Act") was enacted in October 1992 to provide for the funding of health benefits
for retirees who were UMWA retirees. The essential feature of the Health
Benefits Act is to remove the UMWA health benefit plans from the collective
bargaining process and eliminate the per-hour-worked method of funding the UMWA
health benefit plans.  The Health Benefits Act establishes a trust fund to
which "signatory operators," including Old Ben Coal Company, operators who are
signatory to the current NBCWA or prior NBCWAs, and "related persons," are
obligated to pay annual premiums for assigned beneficiaries, together with a
pro rata share for certain beneficiaries ("unassigned beneficiaries") who never
worked for such employers, in amounts to be determined by the Secretary of
Health and Human Services on the basis set forth in the Health Benefits Act.
The expense under this legislation, which is recognized as contributions are
made, amounted to $3.4 million in 1997.  Based upon independent actuarial
estimates, Zeigler believes the amount of its obligation under the legislation
to be approximately $21.6 million as of December 31, 1997, using a 7.25%
discount rate.

REGULATION

     The possibility exists that new legislation and/or regulations may be
adopted which may have a significant impact on Zeigler's mining operations
and/or its customers' ability to use coal and may require the Company or its
customers to change their operations significantly or incur substantial costs.

     Numerous governmental permits or approvals are required for mining
operations.  Zeigler believes all permits currently required to conduct its
present mining operations have been obtained. The Company 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 the Company 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 the
Company and delays, interruptions or a termination of operations, the extent of
which cannot be predicted.

     The Company's independent operating subsidiaries endeavor 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, the Company does not
believe such violations can be completely eliminated.  None of the violations
to date or the monetary penalties assessed upon the Company's subsidiaries have
been material to the Company.

     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 Zeigler made capital
expenditures for environmental control facilities in the amount of
approximately $.6 million in 1997. These costs are in addition to $11.2 million
of reclamation expenditures.  Compliance with these laws has substantially
increased the cost of coal mining, but is, in general, a cost common to all
domestic coal producers.

     Most of the states in which the Company operates have state programs for
mine safety and health regulation and enforcement.  In combination, federal and
state safety and health regulations 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.  The most minute aspects of mine
operations, particularly underground mine operations, are subject to extensive
regulation.  This regulation has a significant effect on the Company's
operating costs.  However, the Company's competitors in all of the areas in
which it operates are subject to the same degree of 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 underground mining, and the effects of mining on groundwater
quality and availability.  In addition, the utility industry is subject to
extensive regulations regarding the environmental impact of its power
generation activities which could affect demand for coal.  The following
summarizes the more significant regulations impacting the industry.

     Clean Air Act Amendments of 1990 - One of the largest challenges the       
     industry has faced is the implementation of the Clean Air Act Amendments
     of 1990 (the "Amendments").  Phase I was effective January 1, 1995 and
     called for a reduction in SO(2) emissions to 2.5 pounds per mmBTU, for
     certain power plants, multiplied by each plant's annual average fuel
     consumption between 1985 and 1987.  Phase II, effective January 1, 2000
     requires further reduction of SO(2) emissions to 1.2 pounds per mmBTU for
     nearly all power plants.  The Amendments  require coal users to either
     purchase lower-sulfur products, invest in scrubbers, or purchase emission
     allowances in order to comply.  The effectiveness of these standards will
     cause an increase in demand for "compliance" coal (coal that emits less
     than 1.2 pounds of SO(2) per mmBTU) with a corresponding decrease in demand
     for higher-sulfur coal. Coal producers have reacted to this trend by
     shifting their investments away from the high-sulfur regions in the
     Midwest towards the lower-sulfur regions such as Appalachia and the
     southern Powder River Basin.  The majority of utilities have been using a
     combination of lower-sulfur coal and emission allowances to meet the
     requirements of Phase I of the Amendments, since the installation of
     scrubbers is both expensive and time consuming.  So far, it has generally
     not been necessary for utilities to drastically change their operations to
     meet the requirements of Phase I.  It is difficult to predict how
     utilities will meet the challenges of the Phase II requirements, and the
     resulting effect on coal demand. The Amendments also require existing
     major sources of nitrogen oxides in moderate or higher ozone
     non-attainment areas to install reasonably available control technology
     ("RACT") for nitrogen oxides, which are precursors of ozone.  The area
     from northern Virginia through Maine has been designated as an ozone
     transport region ("OTR"). Installation of RACT was required by May 1995
     for major sources throughout the OTR and other areas designated as being
     in a moderate or higher state of non-attainment of national ambient air
     standards for ozone.  Such sources generally include coal-fired power
     plants.  A regional commission established for the OTR, the Ozone
     Transport Commission ("OTC"), has been formed to make recommendations to
     the EPA for additional control measures. Both installation of RACT and any
     control measures beyond RACT that the OTC, other states, and the EPA may
     require could make it more costly to operate coal-fired power plants and,
     depending on the requirements of individual state attainment plans and the
     development of revised new source performance standards, could make coal a
     less attractive fuel alternative in the planning and building of power
     plants in the future.

   Comprehensive Environmental Response, Compensation and Liability Act -
   The federal Comprehensive Environmental Response, Compensation and Liability
   Act ("CERCLA") and similar state laws affect coal mining operations by
   imposing clean-up requirements for threatened or actual releases of hazardous
   substances that may endanger public health or welfare or the environment.
   Under CERCLA, 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. Waste substances generated by coal mining and
   processing are generally not regarded as hazardous substances for purposes of
   CERCLA.

   Clean Water Act - The federal Clean Water Act imposes 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 waters.

   Resource Conservation Recovery Act - The federal Resource Conservation
   Recovery Act ("RCRA") imposes 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 SMCRA (defined below) permits are exempted from regulation under
   RCRA by statute, the EPA is studying the possibility of expanding regulation
   of mining wastes under RCRA.

   Surface Mining Control and Reclamation Act - The federal Surface Mining
   Control and Reclamation Act of 1977 ("SMCRA") establishes mining and
   reclamation standards for all aspects of surface mining as well as many
   aspects of deep mining. SMCRA and similar state statutes, among other
   things, require that mined property be restored in accordance with specified
   standards pursuant to an approved reclamation plan.  In addition, the
   Abandoned Mine Lands Act ("AML"), which is part of SMCRA, imposes a tax on
   all current mining operations, the proceeds of which are used to restore
   mines closed before 1977.  The current tax is 35 cents per ton on
   surface-mined coal and 15 cents per ton on underground-mined coal.

   SMCRA also requires that comprehensive environmental protection and
   reclamation standards be met during the course of and upon completion of
   mining activities.  For example, SMCRA requires coal companies to restore a
   surface mine to approximate original contour as contemporaneously as
   practicable with surface coal mining operations.  The mine operator must
   submit a bond or otherwise secure the performance of these reclamation
   obligations.  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 SMCRA, the appropriate state regulatory authority.

   Under SMCRA, 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.

   Mine Health and Safety Acts - Stringent safety and health standards have
   been imposed by federal legislation since 1969 when the federal Coal Mine
   Health and Safety Act of 1969 (the "1969 Act") was adopted.  The 1969 Act
   resulted in increased operating costs and reduced productivity.  The Federal
   Mine Safety and Health Act of 1977 (the "1977 Act") significantly expanded
   the enforcement of health and safety standards. The 1977 Act imposes 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
   ("MSHA") monitors compliance with these federal laws and regulations.  In
   addition, as part of the 1969 Act and the 1977 Act, the Black Lung Benefits
   Act of 1969 and Black Lung Benefits Reform Act of 1977 require payments of
   benefits by all businesses conducting current mining operations to coal
   miners with pneumoconiosis (black lung) as described below.

   Federal Coal Leasing Amendments Act - Mining operations on federal lands in
   the West are also affected by regulations of the U.S. Department of the
   Interior.  The Federal Coal Leasing Amendments Act of 1976 (the "1976 Act")
   amended the Mineral Lands Leasing Act of 1920 which authorized the leasing
   of federal lands for coal mining.  The 1976 Act increased the royalties
   payable to the United States Government for federal coal leases and required
   diligent development and continuous operations of leased reserves within a
   specified period of time.

   Black Lung Benefits - In order to compensate miners who were last employed
   as miners prior to 1970, the Black Lung Benefits Revenue Act of 1977 and the
   Black Lung Benefits Reform Act of 1977, as amended by the Black Lung
   Benefits Revenue Act of 1981 and the Black Lung Benefits Amendments of 1981
   (the "1981 Acts"), levied a tax on production of $1.10 per ton for
   deep-mined coal and $0.55 per ton for surface-mined coal, but not to exceed
   4.4% of the sales price.  In addition, the 1981 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.  Most companies have set aside reserves  for workers last
   employed as miners after 1969.

   EnerZ Corporation is subject to FERC regulation as a wholesale power
marketer and is required to file its rate schedule and quarterly transaction
reports with the FERC.  The Company's other non-mining businesses are also
subject to federal, state and/or local regulation.

expenditures and debt service requirements, restrictions in debt covenants and
other factors that the Board of Directors may deem relevant.

                ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS


                             RESULTS OF OPERATIONS

     Net earnings for the year ended December 31, 1997 were $58.6 million
($2.05 per diluted share)  compared to net earnings of $58.0 million ($2.04 per
diluted share) in 1996 and a net loss of $11.2 million ($.40 per diluted share)
in 1995.

     1997 net earnings benefited significantly from the following items, after
taxes:  (1) a $9.0 million positive change in customer claims expense
representing reversal in 1997 of a $4.5 million contingent claims liability
accrued in 1996, (2) reduced 1997 estimates of Old Ben reclamation liabilities
totaling $8.2 million, (3) a $6.2 million actuarially-based reduction in the
accrued liability for black lung benefits, (4) an unusually large $6.2 million
increase in accrued workers' compensation expense in 1996, and (5) a $3.9
million reduction in net interest expense.  These factors were substantially
offset by the following items, after taxes: (1) a $16.4 million reduction in net
earnings attributable to the 1996 closings of Old Ben Mine #24 and Old Ben Mine
#26, (2) a $12.2 million nonrecurring gain in 1996 on curtailment of
postretirement benefits, (3) a $6.8 million net earnings decrease related to
the December 1996 expiration of Buckskin's contract with Western Farmers
Electric Cooperative("WFEC"), (4) a $5.6 million net loss at EnerZ Corporation,
and (5) a $4.2 million increase in the net loss at the Company's technology
unit.

     The increase in 1996 net earnings compared to 1995 net earnings primarily
reflects nonrecurring provisions in 1995 for asset impairments and accelerated
mine closings of $86.0 million, lower mining costs and higher productivity of
$18.8 million, and the $12.2 million curtailment gain on postretirement
benefits.  These increases were partially offset by nonrecurring 1995 proceeds
from a contract settlement of $34.1 million, a reduction in the pneumoconiosis
benefit obligation of $17.5 million, and lower sales volume and sales prices
mainly related to the 1996 mine closings of $11.3 million.

REVENUES

     Coal sales - Coal sales declined $95.0 million in 1997 compared to 1996,
primarily reflecting the 1996 closures of Old Ben Mine # 24 and Old Ben Mine
#26 ($80.2 million), the 1996 closure of Old Ben Mine #20 ($30.5 million), and
the 1996 expiration of Buckskin's WFEC contract ($20.4 million), partially
offset by the reactivation of Old Ben Mine #11 ($14.3 million) and other small
sales increases.  The $56.5 million decline in 1996 coal sales compared to 1995
was largely due to the three mine closures described above and the 1995 closure
of Old Ben Mine #1 ($42.7 million), and price reductions on two major long-term
coal supply contracts ($13.6 million).

     Energy trading revenues - EnerZ Corporation's energy trading and marketing
activities commenced in January 1997.  Approximately 80% of EnerZ's 1997
revenues were generated from electricity transactions with the remainder 
attributable to natural gas trading.

     Other revenues - Other revenues include throughput fees at the Company's
two east coast transloading terminals; farm, timber, coal trucking, and ash
disposal income; royalty and rental income from land and mineral interests; and
gains from sales of surplus properties.  The 1997 revenue decline was mainly
due to lower revenue from third-party coal leases and timber sales. The 1996
other revenue increase was primarily the result of additional sales of surplus
coal properties.

<PAGE>   24



COSTS AND EXPENSES

     Cost of coal sales  - The decrease in cost of sales from 1996 to 1997
primarily reflects the impact of the 1996 mine closings, and reductions in
certain recorded liabilities.  During 1997, the Company reduced accrued mine
closing costs by approximately $23.4 million, including decreases in the
Old Ben reclamation obligations and contingent claims liabilities referred to
above.  In addition, actuarially-based liability reductions included $3.2
million for postemployment benefits and $2.4 million for postretirement
benefits.  Various other estimated liabilities were reevaluated and reduced in
total by $4.5 million. The decrease in cost of coal sales from 1995 to 1996
principally reflects significantly reduced sales from the closed mines, and
cost savings from idling Wolf Creek Collieries Mine #4 and outsourcing coal
formerly supplied by the idled mine.

     Energy trading costs - The increase in 1997 energy trading costs reflects
EnerZ's first year of operations.

     Other costs and expenses - These amounts are directly associated with
"other revenues" described above.  The increase in 1997 as compared to 1996
costs is largely due to higher costs for operating the Encoal plant after the
1996 expiration of Department of Energy co-funding.  The increase from 1995 to
1996 was mainly attributable to the timing of federal government cost-sharing
receipts at the Encoal plant.

     Selling, general and administrative expenses - Lower 1997 expenses were
mainly the result of lower stock appreciation unit and compensation-related
charges and the timing of other expenses.  Higher 1996 expenses were largely
due to expanded business development activities.

     Gain on curtailment of postretirement benefits - The 1996 curtailment gain
represents a reduction in the Company's recorded obligation to provide retiree
medical benefits to certain former Midwestern mining employees as a result of
their re-employment or termination prior to vesting.

     Reduction in accrued pneumoconiosis benefits - The 1997 and 1995 liability
decreases were based on updated actuarial estimates that recognized positive
trends in claims experience.

     Provision for asset impairments and accelerated mine closings - In July
1995, Old Ben closed   Mine #1, which resulted in a $32.3 million charge to
earnings.  In October 1995, the Company idled the high-cost Wolf Creek Mine #4
and took a related $33.3 million charge to earnings.  In December 1995, the
Company recorded impairment losses totaling $49.1 million upon idling Old Ben
Mine #11 and developing plans to close Old Ben Mine #24 and Old Ben Mine #26.


OTHER

     Proceeds from contract settlement - The Company received cash payments
totaling $45.5 million in 1995 in connection with the settlement of litigation
concerning a contract with Southern Indiana Gas and Electric Company.

     Net interest expense - Lower expense in 1997 primarily reflects higher
interest income earned due to larger cash investments and capitalized interest
on the development of the North Rochelle Mine.  Lower 1996 expense primarily
resulted from lower average borrowings.

     Income taxes (benefit) - Slightly lower pretax income and a lower tax rate
were responsible for the decrease in income taxes from 1996 to 1997.  Higher
pretax income was responsible for the increase in income taxes from 1995 to
1996.  The Company's effective tax rate was 15.0% in 1997 versus 16.3% in 1996
and 28.6% in 1995.  The 1997 and 1996 rate improvements were mainly due to the
benefits of tax loss carryforwards.


                                      22

<PAGE>   25


     The valuation allowance on deferred tax assets decreased $10.5 million
from 1996 to 1997.  This valuation allowance primarily relates to alternative
minimum tax ("AMT") credit carryforwards.  Although management believes that it
is unlikely to realize all of its AMT credit carryforward under existing law
and company structure, AMT credit carryforward is recognized to reduce the
deferred tax liability from the amount of regular tax on temporary differences
to the amount of tentative minimum tax on AMT temporary differences.


                              FINANCIAL CONDITION

     As of December 31, 1997, cash and equivalents totaled $103.3 million, down
from $108.3 million at December 31, 1996.  Cash generated from operating
activities was $79.8 million in 1997, compared to $131.9 million in 1996, and
$114.8 million in 1995 (excluding proceeds from 1995 contract settlement).

     Working capital was $22.2 million and $84.9 million at December 31, 1997
and 1996, respectively.  Accounts receivable and accounts payable have
increased $38.0 million and $42.6 million, respectively, in 1997 due to energy
trading activities at EnerZ Corporation.  Current maturities of long-term debt
represent the cash paid in January 1998 related to the early extinguishment of
the senior secured notes.  The noncash reduction in mine closing-related
liabilities contributed to the $12.7 million reduction in other accrued
expenses.

     Investing activities consumed $70.7 million in cash during 1997, compared
to $30.5 million in 1996 and $51.8 million in 1995.  In addition to $21.8
million in expenditures related to the development of the North Rochelle mine,
the Company continued to invest in property, plant and equipment needed to      
support business growth and improve productivity.  The Company expects to spend
approximately $105.0 million for capital additions during 1998, including
approximately $61.0 million for continued development of the North Rochelle 
mine. The Company anticipates that, if Louisiana Generating LLC is successful
in its bid to purchase the non-nuclear assets of Cajun Electric Power
Cooperative, Inc., the Company's investment in Louisiana Generating LLC will be
approximately $80.0 million.

     The Company used $14.1 million in cash for financing activities in 1997,
up from $6.1 million in 1996 but down from $111.0 million in 1995.  The major
applications of cash in 1997 were dividend payments and purchase of treasury
stock.  The major application of cash in 1996 was the payment of dividends.
Financing applications of cash in 1995 included debt repayments and, to a
lesser extent, dividends.

     The ratio of outstanding debt to total capital was 1.94 to 1.00 at
December 31, 1997 compared to 2.60 to 1.00 at December 31, 1996 and 4.23 to
1.00 at December 31, 1995.  The 1997 and 1996 ratio improvements reflect  1997
and 1996 earnings.

     Other sources of liquidity include a $200.0 million revolving credit
facility, of which $13.9 million was available as of December 31, 1997.

     On January 5, 1998, Zeigler prepaid $198.3 million of the 8.61% Senior 
Secured Notes to the Noteholders, using $68.3 million of cash and
borrowing $130.0 million under a new Credit Agreement's revolving credit
facility (see below).  A related yield maintenance premium of $7.6 million was
also paid to the Noteholders as required by the Note Purchase Agreement. 
Accordingly, Zeigler will recognize an extraordinary loss of $8.8 million
($6.6 million net of taxes) in the first quarter of 1998, consisting of the
yield maintenance premium and the write-off of deferred financing costs related
to the early extinguishment of debt.


                                      23

<PAGE>   26

     In April 1997, the Company executed a new Credit Agreement (the "New
Credit Agreement") with certain financial institutions, which provides for
senior unsecured revolving credit and letter of credit facilities aggregating
$700.0 million.  Interest on the revolving credit facility is paid in arrears
based on rates which fluctuate based on the prime rate or a certain Interbank
Offer Rate, as the Company may elect.  Amounts outstanding under the New Credit
Agreement are not secured.  The New Credit Agreement and the facilities 
thereunder terminate five years from the initial advance.  The New Credit
Agreement requires the Company to maintain a minimum net worth and maximum
long-term debt to EBITDA ratio, and contains other customary covenants and
events of default.  The New Credit Agreement, which replaces the Amended and
Restated Credit Agreement dated October 19, 1994, became effective on January
5, 1998, in conjunction with the payment of the Company's outstanding 8.61%
Senior Secured Notes.

     The Company believes that it has the financial resources and borrowing
capacity needed to meet business requirements in the foreseeable future.


                                    OUTLOOK

     "Safe Harbor" Statement Under the Private Securities Litigation Reform Act
of 1995 - The following Outlook and other items of this Report on Form 10-K

inherent in the Company's business.  The Company's actual results could differ
materially from those anticipated in these forward-looking statements as a
result of certain factors, including those set forth herein and elsewhere in
documents filed with the Securities and Exchange Commission, including, without
limitation, the Company's Forms 10-K and 10-Q.  Forward-looking statements made
by the Company are used to describe business operations that fall into four
areas of operation.  Those operations are subject to factors that can
negatively or positively affect the Company's results as follows:


- -    Coal:  The Company's coal operations can be negatively or positively
     impacted by factors including, but not limited to, weather; unexpected
     maintenance problems; variations in coal seam thickness, amount of
     overburden, rock and other natural materials; disruption of transportation
     services; labor problems; disputes and/or interruption of deliveries under
     coal contracts due to circumstances affecting the customer; regulatory
     uncertainties; legal proceedings; and other conditions.

- -    Liquids from Coal (LFC) Technology:  The Company's technology operations,
     specifically the LFC clean coal technology, can be negatively or
     positively impacted by factors including, without limitation, the unproved
     commercial viability of the technology being developed; permitting and
     other regulatory uncertainties; the ability to obtain financing on
     acceptable terms; competition in the marketplace and uncertain demand for
     the output produced by the LFC process; engineering and construction
     risks; and other conditions.
        

- -    Power:  The Company's operations in this area can be negatively or 
     positively impacted by factors including, but not limited to, whether the
     Company's joint proposal to acquire out of bankruptcy the non-nuclear
     assets of Cajun Electric Power Cooperative, Inc. is confirmed by the
     bankruptcy court and approved by the relevant regulatory authorities;
     regulatory changes that limit or slow the advance of deregulation in the
     utility marketplace; competition in the wholesale power market;
     interruptions and uncertainties relating to fuel supply and
     transportation; and other conditions.

- -    Asset Management:  The Company's operations in the area of asset
     management can be negatively or positively impacted by factors including,
     but not limited to, weather; unexpected maintenance problems; permitting
     and other regulatory uncertainties; legal proceedings; and other
     conditions.


     Possible Sale of Company - On December 3, 1997, the Company announced
that it was retaining an investment banking firm to explore various strategic
alternatives to maximize value for shareholders, including the possible sale of
the entire Company.  In connection therewith, the Board of Directors adopted a
change-in-control severance plan and retention bonus plan for all salaried
employees as well as special incentives for certain key employees.  The Company
has since retained the investment banking firm Credit Suisse First Boston and
prepared materials for interested parties.  The following estimates for 1998
may be affected by the possible sale of the Company or other strategic
alternatives.

     Estimates for 1998 - The Company's five largest customers are expected to
account for approximately 46% of total 1998 revenues, down from 52% in 1997.
Management has targeted further productivity gains in the coal segment.  The
Company's estimated effective tax rate for 1998 is approximately 20%.  The
Company expects that capital expenditures, excluding major acquisitions, will
increase to approximately $105 million in 1998.  In addition to planned
expenditures, incremental strategic investments will be considered on a
case-by-case basis.  Depreciation, depletion and amortization expense is
expected to range between $65 and $70 million for the year.

     Year 2000 Compliance - The inability of computers, software and other
equipment utilizing microprocessors to recognize and properly process data
fields containing a 2 digit year is commonly referred to as the Year 2000
compliance issue.  Such systems will be unable to properly interpret dates
beyond the year 1999, which could lead to business disruptions in the U.S. and
internationally.  The potential costs and uncertainties associated with the
Year 2000 issue will depend on a number of factors, including software,
hardware and the nature of the industry in which a company operates.
Additionally, companies must coordinate with other entities with which they
electronically interact, such as customers, creditors and borrowers.

     The Company has identified all significant applications that will require
modification to ensure Year 2000 compliance.  The modification of all
internally developed applications is substantially complete.  The Company
expects to complete testing of the majority of all significant external
applications by early 1999.

     In addition, the Company is in the process of communicating with others
with whom it does significant business to determine their Year 2000 compliance
readiness and the extent to which the Company is vulnerable to any third party
Year 2000 issues.  However, there can no guarantee that the systems of other
companies on which the Company's systems rely will be timely converted, or that
a failure to convert by another company, or a conversion that is incompatible
with the Company's systems, would not have material adverse effect on the
Company.

     The total cost to the Company of these Year 2000 compliance activities has
not been, and is not anticipated to be material to its financial position or
results of operations in any given year.  These costs and the date on which the
Company plans to complete the Year 2000 modification and testing processes are
based on management's best estimates, which were derived utilizing numerous
assumptions of future events including the continued availability of certain

could differ from those plans.

     LFC Technology - In 1997, upon completion of planned development, the
Company idled Encoal Corporation's clean coal demonstration plant in Wyoming.  
In 1998, marketing of the LFC technology, both domestically and
internationally, will continue as well as the evaluation of options regarding
Encoal.  The net book value of Encoal Corporation's assets and the Company's
related investment in clean coal technology was $6.7 million as of December 31,
1997.

     Inflation - Inflation may have a significant effect on the Company's
revenues and expenses.  Most of the Company's long-term contracts provide for
the adjustment over time of certain components of revenue either through
indices, formulas or direct pass-through of costs.  These long-term contract
provisions help mitigate some of the effects of increasing costs.  Due to the
capital-intensive nature of the Company's activities, inflation may also have a
significant impact on the development or acquisition of mining operations, the
future cost of final mine reclamation and the satisfaction of other long-term
liabilities, such as health care or pneumoconiosis (black lung) benefits.

                          INDEPENDENT AUDITORS' REPORT




To Zeigler Coal Holding Company:

     We have audited the accompanying consolidated balance sheets of Zeigler
Coal Holding Company and Subsidiaries as of December 31, 1997 and 1996, and the
related consolidated statements of operations, cash flows and shareholders'
equity for each of the three years in the period ended December 31, 1997.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

     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, such consolidated financial statements present fairly, in
all material respects, the financial position of the Company and its
subsidiaries at December 31, 1997 and 1996, and the 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.

                 ZEIGLER COAL HOLDING COMPANY AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                 YEARS ENDED DECEMBER 31, 1997, 1996, AND 1995

           (Amounts in thousands, except share and per share amounts)



1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles of Consolidation - The consolidated financial statements
include the accounts of Zeigler Coal Holding Company and Subsidiaries (Zeigler
or the "Company"), all of which are wholly-owned.  All material 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 reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities at the
balance sheet date, and the reported amounts of revenues and expenses during
the year.  Actual results could differ from those estimates.

     Cash and Equivalents - Cash and equivalents include cash on deposit and
highly liquid investments with a maturity of three months or less.

     Inventories - Coal inventory is valued using the average cost method and
is stated at the lower of cost or market.  Coal inventory costs include labor,
equipment costs and operating overhead.  Coal work in process includes
partially uncovered coal and unprocessed coal.  Mine supply inventory is valued
using the average cost method and is stated at the lower of cost or market.

     Property, Plant and Equipment - Additions and betterments are capitalized
at cost.  Maintenance and repair costs are expensed as incurred.  Depreciation
of plant and equipment is computed principally by the straight-line method over
the expected useful lives of the assets.

     Mine development costs and the net amount of associated interest cost are
capitalized.  Exploration costs are expensed as incurred.  Depletion of mineral
rights and capitalized mine development costs is provided on the basis of
tonnage mined in relation to total estimated recoverable tonnage.

     Zeigler pays royalties to certain landowners and holders of mineral
interests for the rights to perform certain mining activities.  Amounts
advanced to landowners, which are recoupable against future production, are
capitalized; as the coal is mined, these prepayments are offset against earned
royalties and included in the cost of coal sales.

     Deferred Financing Costs - The costs of issuing and restructuring
long-term debt are capitalized and amortized using the effective interest
method over the term of the related debt.

     Income Taxes - Zeigler accounts for income taxes in accordance with
Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for
Income Taxes.  Under SFAS No. 109, deferred taxes are established for the
temporary differences between the financial reporting basis and the tax basis
of Zeigler's assets and liabilities at enacted tax rates expected to be in
effect when such amounts are realized or settled.

                 ZEIGLER COAL HOLDING COMPANY AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


     Postretirement Benefits Other Than Pensions - As prescribed by SFAS No. 
106, Employers' Accounting for Postretirement Benefits Other Than Pensions,
Zeigler accrues, based on annual independent actuarial valuations, for
the expected costs of providing postretirement benefits other than pensions,
primarily medical benefits, during an employee's actual working career until
vested.

     Pneumoconiosis Benefits - Certain Zeigler subsidiaries are liable under
the Federal Black Lung Benefits Act of 1972, as amended, to pay pneumoconiosis
(black lung) benefits to eligible employees, former employees and their
dependents for claims filed after June 30, 1973.  These subsidiaries are also
liable under certain state statutes for black lung claims.  Zeigler acts as
self-insurer for most federal and state black lung benefits.  The remaining
portion of black lung claims are covered by state insurance funds into which
Zeigler pays premiums.

     The accrual for self-insured pneumoconiosis benefits is adjusted to equal
the present value of future claim payments, determined as of the beginning of
the year, based on outside actuarial valuations performed annually.

     Postemployment Benefits - Zeigler provides certain postemployment
benefits, primarily long-term disability and medical benefits, to former and
inactive employees and their dependents during the time period following
employment but before retirement.  The Company accrues the discounted present
value of expected future benefits, determined as of the beginning of the year,
based on annual outside actuarial valuations.

     Reclamation and Mine Closing Costs - Zeigler provides for the estimated
costs of future mine closings over the expected lives of active mines.  Those
costs relate to sealing portals at deep mines and to reclaiming the final pit
and support acreage at surface mines.  Other costs common to both types of
mining are related to removing or covering refuse piles and slurry (or
settling) ponds and dismantling preparation plants and other facilities.  The
regular provision for future mine closing costs is calculated under the
units-of-production method based on a per ton charge determined by dividing
estimated unrecorded closing costs by estimated remaining recoverable tons.
These estimates are updated annually and the accrual rate is adjusted on a
prospective basis accordingly.  The cost of restoring land and water resources
affected by normal ongoing surface mining operations is expensed as incurred.

     Asset Impairments and Accelerated Mine Closing Accruals - In certain
situations, expected mine lives are shortened because of changes to planned
operations.  When that occurs, and it is determined that the mine's underlying
costs are not recoverable in the future, reclamation and mine closing   
obligations are accelerated and the mine closing accrual is increased
accordingly.  Also, to the extent that it is determined that asset carrying
values will not be recoverable during a shorter mine life, a provision for such
impairment is recognized. The Company adopted SFAS No. 121, Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of in
1995.  SFAS No. 121 expanded the Company's criteria for loss recognition, and
provides methods for both determining when an impairment has occurred and for
measuring the amount of the impairment.  SFAS No. 121 requires that projected
future cash flows from use and disposition of all the Company's assets be
compared with the carrying amounts of those assets.  When the sum of projected
cash flows is less than the carrying amount, impairment losses are recognized.

     Revenue Recognition - Coal sales are recognized at contract prices at the
time title transfers to the customer. Coal sales are reduced and an allowance
is established for pricing disputes.  Revenue at the import/export terminals is
recognized at the time of throughput.

        Energy Trading Revenues and Costs - Energy trading revenues and costs 
represent revenues and costs derived from the trading of power and gas forward
and future contracts and options. These forward and future contracts and
options are marked-to-market with gains and losses recognized currently. 
Revenue and cost on forward and future contracts is recognized on settlement
date.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


     Other Revenues, Costs and Expenses - Other revenues represent amounts
primarily related to the terminals, coal leases to third parties, farming,
timber, gains on sales of surplus assets, and oil and gas royalties.  Costs and
expenses related to other revenues and those related to Zeigler's clean coal
plant are included in other costs and expenses.

     Stock-Based Compensation - In October 1995, the Financial Accounting
Standards Board issued SFAS No. 123, Accounting for Stock-Based Compensation,
which required adoption in 1996.  The new standard defines a fair value method
of accounting for stock options and similar equity instruments.  Pursuant to
the new standard, companies are encouraged, but not required, to adopt the fair
value method of accounting for employee stock-based transactions.  Companies
are also permitted to continue to account for such transactions under
Accounting Principles Board Opinion (APB) No. 25, Accounting for Stock Issued
to Employees, but are required to disclose in a note to the financial
statements pro forma net income and earnings per share as if the Company had
applied the new method of accounting.  The accounting requirements of the new
method are effective for all employee awards granted after the beginning of the
fiscal year of adoption.  The Company has elected to continue to account for
such transactions under APB No. 25.

     Net Earnings Per Common Share - The Company adopted  SFAS No. 128,
Earnings Per Share, beginning with the Company's fourth quarter of 1997.  All
prior period net earnings per common share data have been restated to conform
to the provisions of this statement.  Basic net earnings per common share is
computed using the weighted average number of shares outstanding.  Diluted net
earnings per common share is computed using the weighted average number of
shares outstanding adjusted for the incremental shares attributed to
outstanding options to purchase common stock.  Incremental shares of 385,000
and 121,000 in 1997 and 1996, respectively, were used in the calculation of
diluted earnings per common share.  Options to purchase 334,000 and 809,000
shares of common stock in 1997 and 1996, respectively, were not included in the
computation of diluted earnings per common share because the option exercise
price was greater than the average market price of the common stock.  All
options to purchase common stock were excluded in the 1995 computation of
diluted earnings per common share since the options were antidilutive.

     Reclassifications - Certain amounts in the 1996 and 1995 financial
statements and notes have been reclassified to conform with the 1997
presentation.


2.  DESCRIPTION OF BUSINESS

     Zeigler is engaged principally in the mining of coal for sale primarily to
electric utilities in the United States.  In addition, during 1997, the Company
began power and gas trading through its new energy trading and marketing
subsidiary, EnerZ Corporation.

3.  INCOME TAXES

     Income tax expense (benefit) is comprised of the following:

     Zeigler also has an AMT credit carryforward of $33,811 and $32,419 at
December 31, 1997 and 1996, respectively, available to be used in future
periods.  Although management believes that it is unlikely to realize all of
its AMT credit carryforward under existing law and company structure, AMT
credit carryforward is recognized to reduce the deferred tax liability from the
amount of regular tax on temporary differences to the amount of tentative
minimum tax on AMT temporary differences.

</TABLE>


     8.61% Senior Secured Notes - The 8.61% Senior Secured Notes are payable to
a group of insurance companies and other financial institutions under Note
Purchase Agreements dated as of November 16, 1992.  Interest on the notes is
payable semiannually.  Annual principal payments begin on November 15, 1998 at
the rate of 20% of the original outstanding amount of $400,000.  The notes
require Zeigler to offer to make mandatory prepayments in the event Zeigler
generates excess cash flow, as defined in the Note Purchase Agreements, or
makes asset sales above specified levels.  The amount of excess cash flow that
must be offered as a prepayment to the Noteholders is based upon the percentage
of debt due to the Noteholders divided by the total indebtedness to both the
Noteholders and the lenders under the Credit Agreement described in the fourth
following paragraph.  The Noteholders were offered a prepayment of $25,050 in
1997 based on free cash flow, as defined, for 1996, of which $628 of the
prepayments were accepted by the Noteholders.

     The notes are collateralized by a first mortgage on substantially all of
Zeigler's assets.  The collateral is shared pari passu with the lenders
involved with the Credit Agreement. The notes may be prepaid at Zeigler's
discretion; however, the Noteholders are entitled to receive a prepayment
premium that protects the yield to the Noteholders over the remainder of the
term of notes.  In effect, this yield maintenance premium is the net present
value of the reduced yield to the Noteholders over the remaining scheduled term 
of the Notes based upon an assumed reinvestment rate of 50 basis points (0.5%)
over the then available yield for U.S. Treasury securities with a maturity
equal to that of the Senior Secured Notes.  No yield maintenance premium is 
payable on mandatory prepayments out of excess cash flow.

     On January 5, 1998, Zeigler prepaid $198,342 to the Noteholders, using 
$68,342 of cash and borrowing $130,000 under a new Credit Agreement's revolving
credit  facility (see below).  A related yield maintenance premium of $7,604
was also paid to the Noteholders as required by the Note Purchase Agreement.
Accordingly, Zeigler will recognize an extraordinary loss of $8,849 ($6,637 net
of taxes) in the first quarter of 1998, consisting of the yield maintenance
premium and the write-off of deferred financing costs related to the early
extinguishment of debt.

     Industrial Revenue Bonds - In August 1997, the Company completed the
refunding of its industrial revenue bonds.  The industrial revenue bonds are
floating rate obligations issued by the Peninsula Ports Authority of Virginia
($115,000) and Charleston County, South Carolina ($30,800).  Both obligations
are backed by letters of credit issued under the Company's revolving credit
facility.  These refundings served to extend the maturities of the industrial
revenue bonds and to release Shell Oil Company from its guarantees of the
underlying obligations.  The principal of the obligation by the Peninsula Ports
Authority of Virginia is due in one lump-sum payment on May 1, 2022, and the
principal of the obligation by Charleston County, South Carolina is due in one
lump-sum payment on August 1, 2028.  Interest on these obligations is payable
monthly.  The weighted average interest rate for these borrowings was 3.66% and
3.38% as of December 31, 1997 and 1996, respectively.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


     Credit Agreement - On October 19, 1994, Zeigler amended and restated its
Credit Agreement dated November 16, 1992, as previously amended and restated on
March 15, 1994.  The Credit Agreement provides for a $200,000 revolving credit
facility, with a three year term, and can be used for both loans and letters of 
credit. As of December 31, 1997, Zeigler had used $186,107 out of the total
$200,000 revolving credit facility for outstanding letters of credit.  The
provisions of the Credit Agreement require a commitment fee to be paid on the
unused portion of the revolving credit facility.  Interest is paid based on 
floating rates which fluctuate based on the prime rate, or the London Interbank
Offer Rate (LIBOR) plus various increments.  The interest rate was 6.42% at
December 31, 1997.  The Credit Agreement is collateralized by a first mortgage
on substantially all of Zeigler's assets.  The collateral is shared pari passu
with the holders of the Senior Secured Notes.

     In April 1997, the Company executed a new Credit Agreement (the "New
Credit Agreement") with certain financial institutions, which provides for
senior unsecured revolving credit and letter of credit facilities aggregating
$700,000.  Interest on the revolving credit facility is paid in arrears based
on rates which fluctuate based on the prime rate or a certain Interbank Offer
Rate, as the Company may elect.  Amounts outstanding under the New Credit
Agreement are not secured.  The New Credit Agreement and the facilities
thereunder terminate five years from the initial advance.  The New Credit
Agreement requires the Company to maintain a minimum net worth and maximum
long-term debt to EBITDA ratio, and contains other customary covenants and
events of default.  The New Credit Agreement, which replaces the
Amended and Restated Credit Agreement dated October 19, 1994, became effective
on January 5, 1998, in conjunction with the payment of the Company's
outstanding Senior Secured Notes.


     Maturities - At December 31, 1997, aggregate scheduled maturities of all
long-term debt for each year through 2002 are as follows:


                      1998 ...................  $ 68,342
                      1999 ...................         -

                                                ========



5.  FINANCIAL INSTRUMENTS

     The fair value of Zeigler's long-term debt has been calculated based on
quoted market prices for similar issues or current rates offered to Zeigler for
debt of the remaining maturities.  Long-term debt has an estimated fair value
of $351,746 and $349,451 compared to the carrying amount of $344,142 and
$344,770 at December 31, 1997 and 1996, respectively.  The carrying amount of
all other financial instruments, including cash and equivalents, accounts
receivable and accounts payable approximates fair value due to the short-term
nature of these instruments.

     Through its energy trading subsidiary, the Company began entering into
power and gas forward contracts and options for trading purposes in 1997.
These forward contracts and options were marked-to-market with any gains and
losses recognized currently.  At December 31, 1997, open net contract and
option positions were not material and did not represent significant credit
related exposure.

6.  PENSION AND SAVINGS PLANS

     Salaried Pension Plan - Zeigler has a non-contributory pension plan
covering substantially all employees other than those who are members of the
United Mine Workers of America ("UMWA").  The plan is a cash balance retirement
plan which provides benefits based upon the employee's length of credited
service and compensation during each year of employment.  Zeigler's funding
policy is to make, as a minimum contribution, the equivalent of the minimum
payment required by the Employee Retirement Income Security Act of 1974.  The
Company contributed $123 in 1997 to the pension plan.  There were no minimum
contributions required in 1996 and 1995.

     The pension cost components for the year ended December 31, are as

respective contracts with the UMWA to pay amounts based on hours worked to the
UMWA Pension Plan and Trust, a multi-employer pension plan covering all
employees who are members of the UMWA.  The accompanying consolidated
statements of operations include $1,578, $2,102, and $2,778, of expense in
1997, 1996, and 1995, respectively, applicable to the plan.  The National
Bituminous Coal Wage Agreement of 1998 ("NBCWA") authorizes the Bituminous Coal
Operators Association to increase the rate of contributions from employers to
assure payment of benefits.  The union contract requires all currently
participating employers to guarantee benefits jointly, but not severally, with
all other currently participating employers.  It is not practical to determine
each subsidiaries' allocable share of the plan's net assets and accumulated
benefits.

     401(k) Plans - Zeigler and certain subsidiaries sponsor savings and
long-term investment plans for substantially all employees other than employees
covered by the contract with the UMWA.  One of the plans will match 50% of the
voluntary contributions up to a maximum contribution of 3% of a participant's
salary with an additional matching contribution subject to certain performance
criteria.  The expense under these plans was $1,276, $1,391, and $1,036, in
1997, 1996 and 1995, respectively.

     Stock Appreciation Units - Zeigler has a long-term incentive plan which
entitles certain officers and key employees to receive a cash award for an
amount equal to the excess of the fair market value of Zeigler's common stock
on the date the unit matures over the base price at the date of grant of the
award.  The plan permits an aggregate of 1,635,200 such stock appreciation
units of which 73,600 and 284,320 were outstanding at December 31, 1997 and
1996, respectively. The vesting period ranges from three to five years. During
1997, 210,080 stock appreciation units matured.  Costs and expenses include
approximately $141, $2,917, and $3,178, of charges in connection with this plan
for 1997, 1996 and 1995, respectively. Outstanding stock appreciation units
with maturities less than one year are included as a component of other accrued
expenses.

7.  POSTRETIREMENT BENEFITS OTHER THAN PENSIONS

     UMWA Combined Benefit Fund - Zeigler provides healthcare benefits to
eligible retirees and their dependents.  Retirees who were members of the UMWA
and who retired on or before December 31, 1975 received these benefits from
multi-employer benefit plans.  Old Ben contributed to these funds based on the
number of its retirees in one of the funds and based on hours worked by current
UMWA members for the other fund.  Current and projected operating deficits of
these trusts led to the passage of the Coal Industry Retiree Health Benefit Act
of 1992 (the "Act").  The Act established a new multi-employer benefit trust
that will provide healthcare and life insurance benefits to all beneficiaries
of the earlier trusts who were receiving benefits as of July 20, 1992. The Act
provides for the assignment of beneficiaries to their former employers and any
unassigned beneficiaries to employers based on a formula.  The expense under
these plans, which is recognized as contributions are made, amounted to $3,431,
$2,968, and $3,527, in 1997, 1996 and 1995, respectively.  Based upon an
independent actuarial valuation, Zeigler estimates the amount of its obligation
under the new plan to be approximately $21,637 as of December 31, 1997.

</TABLE>


     In 1996, as a result of the re-employment or termination prior to vesting
of certain Midwestern employees, the Company recorded a $16,295 gain related to
the curtailment of its postretirement benefit plan.

     The discount rate used to determine the accumulated postretirement benefit
obligation was 7.25% and 7.5% at December 31, 1997 and January 1, 1997,
respectively.  The assumed healthcare cost trend rates used in determining the
net expense for 1997 are shown in the following table.  Healthcare cost trends
were assumed to decline from 1997 levels to an ultimate ongoing level over five
years as follows:


<TABLE>
<CAPTION>
                                           1997  Ultimate
                                           Rate    Rate
                                           ----  --------
        <S>                               <C>      <C>

         Post-65 .......................   6.5%     5.0%
         Medicare offset ...............   6.0%     5.0%
</TABLE>



     The expense and liability estimates can fluctuate by significant amounts
based upon the assumptions used by the actuaries.  If the healthcare cost trend
rates were increased by one percent in each year, the accumulated postretirement
benefit obligation would be 14 percent higher as of December 31, 1997.  The
effect of this change on the 1997 expense accrual would be an increase of 14
percent.

8.  PNEUMOCONIOSIS BENEFITS

     The actuarially determined liability for pneumoconiosis (black lung)
benefits is based on a 6% discount rate and various other assumptions including
incidence of claims, benefit escalation, terminations and life expectancy.  The 
annual black lung expense is comprised of the net change in the beginning
accrual balance, a charge for interest on the unfunded accrual balance plus the
premiums paid to the state insurance funds.  The January 1, 1997 and January 1,
1995 actuarial studies reduced the estimated pneumoconiosis liability by $8,244
and $23,299, respectively, as compared to the previous study.  The lower 
estimates resulted primarily from favorable claims experience and reduced
projected future claims.

     The cost of black lung benefits charged to operations for Zeigler and its
subsidiaries, excluding the changes in estimated liability mentioned above, was
$2,280, $157, and $2,967 in 1997, 1996 and 1995, respectively.


9.  STOCK OPTION PLAN


     In February 1994, Zeigler's Board of Directors and shareholders adopted a
Stock Option Plan (the "Option Plan").  A total of 2,560,000 shares of Common
Stock are reserved for issuance upon exercise of options granted under the
Option Plan.  The Option Plan is administered by the Compensation Committee of
the Board of Directors which determines the terms of the options granted
including the exercise price, number of shares subject to the option and
exercisability.

     The Company applies APB Opinion No. 25, Accounting for Stock Issued to
Employees, and related Interpretations in accounting for its plan.  The Company
has adopted the disclosure-only provisions of SFAS No. 123, Accounting for
Stock-Based Compensation.  Accordingly, no compensation cost has been
recognized for the stock option plan.

     The following summarizes the stock option transactions under the Option
Plan for the three years ended December 31, 1997:

                 ZEIGLER COAL HOLDING COMPANY AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

     The outstanding stock options at December 31, 1997, 1996 and 1995 have a
weighted average remaining contractual life of 7.64, 8.28, and 8.51 years,
respectively.  The number of stock option shares exercisable at December 31,
1997, 1996, and 1995 were 717,464, 362,710, and 213,400, respectively.

     Generally, stock options are granted at prices which are equal to the
market value of the stock on the date of grant, have a maximum term of ten
years, and vest in equal annual increments over five years.  The weighted
average fair value at date of grant for options granted during 1997, 1996, and
1995 was $10.66, $5.76, and $3.96 per option, respectively.  The fair value of
options at date of grant was estimated using the Black-Scholes model with the
following weighted average assumptions:

     As previously discussed, the Company accounts for the Option Plan in
accordance with APB No. 25 under which no compensation expense has been
recognized for stock option awards.  Had compensation cost for the Company's
stock option plan been determined on the fair value at the grant date for
awards for the three year period ended December 31, 1997 consistent with the
provisions of SFAS No. 123, the Company's net earnings (loss) and earnings
(loss) per share would have been reduced to the pro forma amounts indicated

</TABLE>

     In July 1995, the Company closed Old Ben Mine #1 in Indiana after
termination of its supply contract with Southern Indiana Gas and Electric
Company.  Accordingly, the carrying value of the mine and other related assets
that supported the contract were reduced to their estimated net realizable
values, which resulted in asset write-downs of $15,762.  In addition, a
provision for accelerated mine closing costs of $16,500 was recorded, based on
the amount of estimated closing costs that would have been expensed during the
full term of the contract.

     In the fourth quarter of 1995, the Company recorded asset impairments and
accelerated accruals totaling $82,400 in connection with the idling, closing
and projected closing of certain mines.  Of that amount, $49,100 relates to Old
Ben's operations in southern Illinois.  Old Ben idled one mine in Randolph
County, Illinois  on  December 31, 1995, and  made plans  to  close  two  other
mines in  Franklin County, Illinois later in 1996, mainly due to a sharp
reduction in demand for the Illinois Basin's high-sulfur coal.  Management did
not expect the high-sulfur market to improve significantly in the foreseeable
future.  The remaining $33,300 fourth quarter charge was associated with the
indefinite idling of Wolf Creek's underground mine in eastern Kentucky on
October 1, 1995.  That amount consists of asset write-downs totaling $26,000
and increased reclamation liabilities of $7,300.  Operations were suspended at
the mine chiefly due to the new sourcing flexibility negotiated in the amended
contract with Carolina Power & Light Company which allows the Company to supply
the contract with coal purchased from lower-cost producers.  The ongoing high
costs at the Wolf Creek mine were mainly attributable to unfavorable geology
and declining productivity.  

     11.  SALE OF INDIANA ASSETS

     On February 12, 1996, the Company closed the sale of the majority of its
assets in Indiana to Kindill Mining, Inc. ("Kindill").  These assets had a
combined book value of $13,400 and included Old Ben Mine #1 and Old Ben Mine
#2, along with various other coal properties and interests.  The Company
also agreed to make cash payments to Kindill of $7,000 in 1996 and $4,000 in
1997.  In exchange, Kindill assumed the associated reclamation liabilities,
estimated at approximately $23,400.  This sale was completed on April 30, 1996,
after Kindill secured the required mining permits. The sale of these assets did
not have a material effect on current income.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)

12.  PREFERRED STOCK

     Zeigler is authorized to issue 1,000,000 shares of preferred stock, $0.01
par value, with such issuance to be in one or more classes or series.  The
Board of Directors is authorized to determine the designations, preferences,
qualifications, limitations and restrictions of any class or series with
respect to, among other things, the rate and nature of dividends, the price and
terms, the amount payable in the event of liquidation, the terms and conditions
for conversion or exchange into any other class or series of the stock or other
securities and voting rights.

13.  SIGNIFICANT CUSTOMERS

     Coal sales include transactions involving both produced and purchased
coal.  Two customers accounted for 29% and 16% of coal sales in 1997, 18% and
14% of coal sales in 1996,  and 18% and 13% of coal sales in 1995.

14.  RELATED PARTY TRANSACTIONS

     Shell Oil Company, a former indirect shareholder, provides guarantees for
certain letters of credit and surety bonds of Zeigler.  Zeigler reimburses
Shell for its costs in providing these guarantees.

15.  COMMITMENTS AND CONTINGENCIES (Also see Note 16 - Legal Proceedings)

     Zeigler and its subsidiaries have operating lease commitments expiring at
various dates, primarily for equipment.  Minimum rental obligations under these
leases at December 31, 1997 are summarized by fiscal year as follows:


<TABLE>
                       <S>                    <C>

                                               ======
</TABLE>


     Rental expense relating to operating leases amounted to $7,626, $7,834,
and $9,733 in 1997, 1996 and 1995, respectively.  As of December 31, 1997,
Zeigler and its subsidiaries had $192,571 of surety bonds issued by an
insurance company to secure self-insured workers' compensation and
pneumoconiosis claims, reclamation and other performance commitments.  Of that
amount, $23,061 was backed by guarantees of Shell (see Note 14).  Letters of
credit of $246,161 were outstanding at December 31, 1997, of which amount
$60,053 was also guaranteed by Shell.

     In 1997, upon completion of planned development, the Company idled Encoal
Corporation's clean coal demonstration plant in Wyoming. In 1998, marketing of
the LFC technology, both domestically and internationally will continue as well
as the evaluation of options regarding Encoal.  The net book value of Encoal
Corporation's assets and the Company's related investment in clean coal
technology was $6.7 million as of December 31, 1997.

16.  LEGAL PROCEEDINGS

     Cajun Electric Power Cooperative - On December 21, 1994, Cajun Electric
Power Cooperative Inc.  ("Cajun") filed with the U.S. Bankruptcy Court for the
Middle District of Louisiana (the "Bankruptcy Court") for voluntary
reorganization under Chapter 11 of the U.S. Bankruptcy Code. Triton Coal
Company ("Triton") has a requirements contract (the "Triton Contract") with
Cajun through Western Fuels Association, Inc., with a term extending through
the life of Big Cajun Plant No. 2.   During 1997, Triton shipped 5.8 million
tons of coal to Cajun (representing 3.0% of the Company's total consolidated
revenues), while 1996 shipments to Cajun totaled 5.0 million tons.  To date
during the bankruptcy, Triton has continued to ship coal to Cajun and Cajun has
continued to pay for such coal. The price for coal sold under the Triton
Contract is at or near the market price for this coal.  The Triton Contract
provides for a price reopener effective January 1, 1998.  The parties were
unable to reach agreement on the price to be effective January 1, 1998 and are
attempting to resolve that matter through the procedure set forth in the Triton
Contract.

                 ZEIGLER COAL HOLDING COMPANY AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


     An Appellate Court affirmed a District Court's ruling that a
court-appointed trustee will manage Cajun's affairs during the bankruptcy.  At
this time, it appears likely that the trustee will reject the Triton Contract.
In the event that the contract is rejected, it may be necessary for Triton to
find other markets for this coal, possibly including sales to the new operator
of Cajun's coal fired units.

     Louisiana Generating LLC (an affiliate of the Company, Southern Energy,
Inc. and NRG Energy, Inc.) has executed an Amended and Restated Asset Purchase
and Reorganization Agreement to purchase substantially all of Cajun's
non-nuclear assets.  This Agreement is incorporated in the trustee's plan of
reorganization, which is subject to Bankruptcy Court approval (including
evaluation of competing plans of reorganization) and a number of other
conditions.  As a result of Louisiana Generating's entering into this
Agreement, Western Fuels Association, Inc. has formally requested certain
assurances regarding Triton's performance under the Triton Contract and
informed the Company that it reserves the right to assert certain claims
against Triton if the trustee rejects the Triton Contract.

     Entergy-Gulf States Utilities, Inc. - Entergy-Gulf States, Inc. ("GSU")
owns 42% of Unit 3 at the Big Cajun II coal-fired power station.  Pursuant to
the Triton Contract, Triton supplies the coal requirements of all three units
at Big Cajun II.  Two of the three plans for reorganization of Cajun pending
before the Bankruptcy Court call for the rejection of the Triton Contract.
Triton and Western Fuels Association, Inc. maintain that Unit 3 is a joint
venture between GSU and Cajun, that joint ventures are partnerships under
Louisiana law and that, as Cajun's partner and as a direct beneficiary of the
coal provided by Triton, GSU is liable for some or all of their damages in the
event that the Triton Contract is rejected.  On January 13, 1997, GSU requested
a judgment from the Bankruptcy Court declaring that Cajun is the sole principal
under the Triton Contract and that GSU has no liability to Western Fuels
Association, Inc. or Triton in the event the Triton Contract is rejected.  In
February 1997, Western Fuels Association, Inc. and Triton filed a counterclaim
asking for a declaration from the Bankruptcy Court that GSU is liable to them
for damages if the Triton Contract is rejected.  On September 3, 1997, the 
Bankruptcy Court granted GSU a summary judgment.  Western Fuels Association, 
Inc. and Triton have appealed this judgment.

     On August 21, 1997, GSU filed additional claims against the Company,
Triton and Western Fuels Association, Inc.  In these claims, GSU alleged that
these parties violated the Sherman Antitrust Act and Louisiana Fair Trade
Statutes in the course of settlement discussions between the parties.  The
Company believes that these allegations have no merit and a Motion to Dismiss
these claims is pending.

     If the Triton Contract is rejected by the Bankruptcy Court, Triton will
suffer damages for breach of contract, for which its only remedies will be a
claim against GSU (as described above) and/or a  claim in Cajun's bankruptcy
proceeding as a creditor of Cajun, and Triton will have to find other markets
for this coal, possibly including sales to the new operator of Cajun's
coal-fired units.  Triton is currently in negotiations with alternative
customers for this coal.  Triton has executed an agreement with Louisiana
Generating pursuant to which Triton will supply coal to Big Cajun II in the
event Cajun's court-appointed trustee's plan of reorganization is confirmed by
the Bankruptcy Court and Louisiana Generating completes the purchase of Cajun's
non-nuclear assets.  Triton, Western Fuels Association, Inc., and the Trustee
have also executed an agreement which provides that if Louisiana Generating is
successful in purchasing the Cajun assets and the Triton Contract is rejected,
Triton will release any and all claims in Cajun's bankruptcy and will receive
approximately $4,000.

                 ZEIGLER COAL HOLDING COMPANY AND SUBSIDIARIES

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS - (CONTINUED)


     Janet Saad-Cook et al. v. Zeigler Coal Holding Company and R. & F. Coal
Company - In March, 1995, plaintiff filed a lawsuit against the Company and its
subsidiary, R. & F. Coal Company.   The complaint includes several causes of
action based on alleged actions of the defendant companies involving fraud,
deceit, misrepresentation, and tortuous breach of contract with respect to two
coal mining leases made among the plaintiffs and R. & F. Coal Company. The
plaintiffs' complaint has since been amended to add Bluegrass Coal Development
Company as a named defendant, to eliminate the allegations that the defendants'
behavior violated the U.S. Racketeer Influenced and Corrupt Organizations Act
and to include additional causes of action involving trespass and breach of
lease.  The defendant companies have denied the allegations in the complaint,
believe they have meritorious defenses to plaintiffs' claims, and intend to
defend vigorously against the claims.   The Company believes that Shell Oil
Company is obligated to indemnify the Company against any loss (over certain
minimum amounts) that the Company may incur as a result of plaintiffs' claims
in the litigation and has given Shell notice thereof in accordance with the
terms of the purchase agreement under which the Company acquired Shell Mining
companies. The Company believes that ultimate resolution of the claims in the
lawsuit will have no material adverse effect on the Company's consolidated
results of operations or financial position.

     Other - Various lawsuits and claims, including those involving ordinary
routine matters incidental to its business, to which the Company and its
subsidiaries are a party, are pending, or have been asserted, against the
Company.  Although the outcome of these matters cannot be predicted with
certainty, management believes that their disposition will not have materially
adverse effects on the Company's consolidated results of operations or
financial position.

17.  SEGMENT REPORTING

     The Company adopted SFAS No. 131, Disclosures About Segments of an
Enterprise and Related Information, beginning with the Company's fourth quarter
of 1997.  The Company has two reportable segments: coal and energy.  The coal
segment is engaged in the mining of coal for utilities in the United States.
The energy segment is principally responsible for the trading and marketing of
electricity and natural gas within the U.S.  These reportable segments are
separately managed strategic business units that offer different products and
services, and whose performance is evaluated based on earnings from operations
before interest and taxes, not including nonrecurring gains and losses. The
accounting policies of the segments are the same as those described in Note 1.
There were no sales or transfers between segments in 1997, 1996, or 1995. The
"Other" category below consists of five operating segments that did not meet
the quantitative thresholds for determining reporting segments.  These segments
consist primarily of amounts related to two import/export terminals, a clean
coal plant in Wyoming, the Company's environmental subsidiary, coal leases to
third parties, farming, timber, gains on sales of surplus assets, oil and gas
royalties, and selling, general and administrative costs.

18.  POSSIBLE SALE OF COMPANY

     On December 3, 1997, the Company announced that it was retaining an
investment banking firm to explore various strategic alternatives to maximize
value for shareholders, including the possible sale of the entire Company.  In
connection therewith, the Board of Directors adopted a change-in-control
severance plan and retention bonus plan for all salaried employees as well as
special incentives for certain key employees.  The Company has since retained
the investment banking firm Credit Suisse First Boston and prepared materials
for interested parties.

     independently for each quarter and for the year using the weighted average
     number of common shares and common share equivalents outstanding during
     each period.

affected by the fact that one or more of the officers whose signatures appear
on such Bond have ceased to hold office at the time of issuance or
authentication or at any time thereafter.

     Section 2.04. Authentication.  No Bonds shall be valid for any purpose
hereunder until the certificate of authentication printed thereon is duly
executed by the manual signature of an authorized signatory of the Trustee.
Such authentication shall be proof that the Registered Owner is entitled to the
benefit of the trusts hereby created.

     Section 2.05. Registration, Transfer and Exchange.

             (a)   The ownership of each Bond shall be recorded in the 
     registration books of the Issuer, which books shall be kept by the Trustee,
     acting as bond registrar, at its principal office, and shall contain such
     information as is necessary for the proper discharge of the duties of the
     Trustee hereunder.
        
             (b)   Bonds may be transferred or exchanged as follows:

                   (i)   Any Bond may be transferred if duly endorsed for such 
             transfer or accompanied by an instrument of transfer in form
             satisfactory to the Trustee, duly executed by the Registered Owner
             or his attorney duly authorized in writing and delivered by such
             Registered Owner or his duly appointed attorney to the Trustee,
             whereupon the Trustee shall authenticate and deliver to the
             transferee a new Bond or Bonds and in the same denominations as the
             Bond delivered for transfer or in different authorized
             denominations equal in the aggregate to the principal amount of the
             delivered Bond and accruing interest at the same Interest Rate     
             Mode.
        
                   (ii)  Any Bond or Bonds may be exchanged for one or more 
             Bonds and in the same aggregate principal amount and accruing
             interest at the same Interest Rate Mode, but in a different
             authorized denomination or denominations if duly endorsed or
             accompanied by an instrument of transfer in form satisfactory to
             the Trustee, duly executed by the Registered Owner or his attorney
             duly authorized in writing.  Each Bond so to be exchanged shall be
             delivered by the Registered Owner thereof or his duly appointed
             attorney to the Trustee, whereupon a new Bond or Bonds shall be
             authenticated and delivered to the Registered Owner.
        
                   (iii) In the case of any Bond properly delivered for partial
             redemption, the Trustee shall authenticate and deliver a new Bond
             in exchange therefor, such new Bond to be in a denomination equal
             to the unredeemed principal amount of the delivered Bond.
        
     Except as provided in subparagraph (iii) above or in Article IV hereof,
the Trustee shall not be required to effect any transfer or exchange during the
15 days immediately preceding the date of mailing of any notice of redemption
or at any time following the mailing of any such notice in the case of Bonds
selected for such redemption.  No charge shall be imposed upon Registered
Owners in connection with any transfer or exchange, except for taxes or
governmental charges related thereto.  No transfers or exchanges shall be valid
for any purposes hereunder except as provided above and in Article IV hereof.

     Section 2.06. Mutilated, Destroyed, Lost or Stolen Bonds.

             (a) If any Bond is mutilated, lost, stolen or destroyed, the 
     Registered Owner thereof shall be entitled to the issuance of a 
     substitute Bond provided that:




                                      14
<PAGE>   20



           (i)   in all cases, the Registered Owner may be required by the 
       Issuer, the Company or the Trustee to provide indemnity to the Issuer,
       the Company and the Trustee in a form acceptable to the Issuer and the
       Trustee against any and all claims arising out of or otherwise related
       to the issuance of substitute Bonds pursuant to this Section;
                
           (ii)  in the case of a mutilated Bond the Registered Owner shall
       deliver the Bond to the Trustee for cancellation; and

           (iii) in the case of a lost, stolen or destroyed Bond, the Registered
       Owner shall provide evidence, satisfactory to the Trustee, of the
       ownership and the loss, theft or destruction of the affected Bond.

       Upon compliance with the foregoing, a new Bond of like tenor and
denomination, executed by the Issuer, shall be authenticated by the Trustee and
delivered to the Registered Owner, all at the expense of the Registered Owner to
whom the substitute Bond is delivered.  Notwithstanding the foregoing, the
Trustee shall not be required to authenticate and deliver any substitute for a
Bond which has been called for redemption or which has matured or is about to
mature and, in any such case, the principal or redemption price then due and
accrued interest thereon or becoming due shall be paid by the Trustee in
accordance with the terms of the mutilated, lost, stolen or destroyed Bond
without substitution therefor.
        
       (b) Every substituted Bond issued pursuant to this Section 2.06 shall
constitute an additional contractual obligation of the Issuer, whether or not
the Bond alleged to have been destroyed, lost or stolen shall be at any time
enforceable by anyone, and shall be entitled to all the benefits of this
Indenture equally and proportionately with any and all other Bonds duly issued
hereunder.
        
       (c) All Bonds shall be held and owned upon the express condition that
the foregoing provisions are exclusive with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Bonds, and shall preclude any
and all other rights or remedies, unless expressly inconsistent with any law or
statute existing or hereafter enacted with respect to the replacement or payment
of negotiable instruments, investments or other securities without their
delivery.
        
Section 2.07. Payments of Principal, Redemption Price and Interest; Persons
Entitled Thereto.

       (a) The principal or redemption price of each Bond shall be payable upon
delivery of such Bond to  the Trustee at its principal office.  During Flexible,
Daily or Weekly Rate Periods, the principal or redemption price of the Bonds
shall be payable by wire transfer of immediately available funds. During Term
Rate Periods the principal or redemption price of the Bonds shall be payable by
check in clearinghouse funds, provided that any Registered Owner of $1,000,000
or more in aggregate principal amount of the Bonds may, upon written request
given to the Trustee at least five Business Days prior to the maturity or
redemption date designating an account in a domestic bank, be paid by wire
transfer of immediately available funds.  Such payments shall be made to the
Registered Owner of the Bond so delivered, as shown on the registration books
maintained by the Trustee on the date of payment.
        
       (b) Subject to the further provisions of Article III hereof, each Bond
shall accrue interest and be payable as to interest as follows:





                                      15
<PAGE>   21






                     (i)    Each Bond shall accrue interest (at the applicable
             rate determined pursuant to Article III hereof) (A) from the date
             of authentication, if authenticated on an Interest Payment Date to
             which interest has been paid or duly provided for, or (B) from the
             last preceding Interest Payment Date to which interest has been
             paid in full or duly provided for (or the Issue Date if no interest
             thereon has been paid or duly provided for) in all other cases.
        
                     (ii)   Subject to the provisions of subparagraph (iii) 
             below, the interest due on any Bond on any Interest Payment Date
             shall be paid to the Registered Owner of such Bond as shown on the
             registration books kept by the Trustee as of the Regular Record
             Date.  The amount of interest so payable on any Interest Payment
             Date shall be computed (A) on the basis of a 365- or 366-day year
             for the number of days actually elapsed during Daily Rate Periods,
             (B) on the basis of a 365- or 366-day year for the number of days
             actually elapsed based on the calendar year in which the Flexible
             or Weekly Rate Period commences, during Weekly or Flexible Rate
             Periods, and (C) on the basis of a 360-day year of twelve 30-day
             months during Term Rate Periods.
        
                     (iii)  If the available funds under this Indenture are 
             insufficient on any Interest Payment Date to pay the interest then
             due, the Regular Record Date shall no longer be applicable with
             respect to the Bonds.  If funds for the payment of such overdue
             interest thereafter become available, the Trustee shall immediately
             establish a special interest payment date for the payment of the
             overdue interest and a Special Record Date (which shall be a
             Business Day) for determining the Registered Owners entitled to
             such payments.  Notice of such Special Record Date shall be mailed
             by the Trustee to each Registered Owner promptly after the
             determination of such Special Record Date, but not more than 30
             days prior to the special interest payment date.  The overdue
             interest shall be paid on the special interest payment date to the
             Registered Owners, as shown on the registration books kept by the
             Trustee as of the close of business on the Special Record Date.
        
                      (iv)  All payments of interest on the Bonds shall be 
             paid to the Registered Owner entitled thereto (i) by check mailed
             to such Registered Owner or (ii) in immediately available funds by
             wire transfer to a bank within the continental United States or
             deposited to a designated account if such account is maintained
             with the Trustee as directed by the Registered Owner in writing or
             as otherwise directed in writing by the Registered Owner five
             Business Days prior to the time of payment with respect to Bonds
             accruing interest at a Flexible Rate or two Business Days prior to
             the Interest Payment Date with respect to Bonds accruing interest
             at Daily or Weekly Rates.
        
                      (v)   Interest accrued during any Flexible Rate Period
             or due at the maturity or redemption of the Bonds shall be paid
             only upon presentation and surrender of Bonds.
        
     Section 2.08. Temporary Bonds.  The Issuer may issue, in lieu of
definitive Bonds, one or more temporary printed or typewritten Bonds in
authorized denominations, of substantially the tenor recited above.  At the
request of the Issuer, the Trustee shall authenticate definitive Bonds, which
may be typewritten or printed, in exchange for and upon surrender of an equal
principal amount of temporary Bonds.  Until so exchanged, temporary Bonds shall
have the same rights, remedies and security hereunder as definitive Bonds.
Temporary Bonds shall be numbered consecutively upward from TR-1.


                                      16
<PAGE>   22

     Section 2.09. Cancellation and Disposition of Surrendered Bonds.  The
Trustee shall cancel  (a) all Bonds surrendered for transfer or exchange, for
payment at maturity or for redemption, and (b) all Bonds purchased at the
direction of the Company and surrendered to the Trustee for cancellation, and
the Trustee shall dispose of such Bonds in accordance with the Trustee's 
document retention policies.  The Trustee shall deliver to the Issuer a
certificate of cancellation or disposition in respect of all Bonds cancelled or
disposed of in accordance with this Section.
        
     Section 2.10. Acts of Registered Owners; Evidence of Ownership.  Any
action to be taken by Registered Owners may be evidenced by one or more
concurrent written instruments of similar tenor signed or executed by such
Registered Owners in person or by an agent appointed in writing.  The fact and
date of the execution by any Person of any such instrument may be proved by
acknowledgment before a notary public or other officer empowered to take
acknowledgments or by an affidavit of a witness to such execution or by any
other method satisfactory to the Trustee.  Any action by the Registered Owner
of any Bond shall bind all future Registered Owners of the same Bond or of any
Bond issued upon the exchange or registration of transfer thereof in respect of
anything done or suffered by the Issuer or the Trustee in pursuance thereof.

     Section 2.11. Book Entry System.

     (a) DTC will act as securities depository (the "Securities Depository")
for the Bonds.  The Bonds shall be initially issued in the form of a single
fully registered Bond registered in the name of Cede & Co., as nominee for DTC.
So long as Cede & Co. is the Registered Owner of the Bonds, as nominee of DTC,
references herein to Registered Owners, Bondholders or holders of the Bonds
shall mean Cede & Co. and shall not mean the beneficial owners of the Bonds.

     (b) The interest of each of the beneficial owners of the Bonds will be
recorded through the records of a DTC Participant.  Transfers of beneficial
ownership interests in the Bonds which are registered in the name of Cede & Co.
will be accompanied by book entries made by DTC and, in turn, by the DTC
Participants who act on behalf of the beneficial owners of the Bonds.

     (c) With respect to Bonds registered in the name of Cede & Co. as nominee
of DTC, the Issuer, the Bond Registrar and the Trustee shall have no
responsibility or obligation to any DTC Participant or to any person on behalf
of whom such a DTC Participant holds an interest in the Bonds, except as
provided in this Indenture.  Without limiting the immediately preceding
sentence, the Issuer and the Trustee shall have no responsibility or obligation
with respect to (i) the accuracy of the records of the DTC, Cede & Co. or any
DTC Participant with respect to any ownership interest in the Bonds, (ii) the
delivery to any DTC Participant or any other person, other than a Registered
Owner, as shown on the Registration Books, of any notice with respect to the
Bonds, including any notice of redemption, or (iii) the payment to any DTC
Participant or any other person, other than a Registered Owner, as shown in the
Registration Books of any amount with respect to principal of, premium, if any,
Purchase Price or interest on, the Bonds.

     (d) Notwithstanding any other provisions of this Indenture to the
contrary, the Issuer, the Bond Registrar and the Trustee shall be entitled to
treat and consider the person in whose name each Bond is registered in the
Registration Books as the absolute owner of such Bond for the purpose of
payment of principal, premium, if any, Purchase Price, and interest with
respect to such Bond, for the purpose of giving notices of redemption and other
matters with respect to such Bond, for the purpose of registering transfers
with respect to such Bond, and for all other purposes whatsoever.  The Trustee
shall pay all principal of, premium, if any, Purchase Price, and interest on
the Bonds only to or upon the order of the respective Registered Owners, 



                                      17
<PAGE>   23

as shown in the Registration Books as provided in this Indenture, or their
respective attorneys duly authorized in writing, and all such payments shall be
valid and effective to fully satisfy and discharge the Issuer's obligations with
respect to payment of principal of, premium, if any, Purchase Price, and
interest on, the Bonds to the extent of the sum or sums so paid.
        
     (e) No person other than a Registered Owner, as shown in the Registration
Books, shall receive a Bond certificate evidencing the obligation of the Issuer
to make payments of principal, premium, if any, and interest, pursuant to this
Indenture.

     (f) Any provision of this Indenture permitting or requiring the delivery
of Bonds shall, while the book-entry system is in effect, be satisfied by the
notation on the books of DTC or a DTC Participant, if applicable, of the
transfer of the beneficial owner's interest in such Bond.

     (g) So long as the book-entry system is in effect, the Trustee and the
Bond Registrar shall comply with the terms of the Letter of Representations.

     (h) DTC may determine to discontinue providing its service with respect to
the Bonds at any time by giving written notice and all relevant information on
the beneficial owners of the Bonds to the Issuer, the Company and the Trustee
and discharging its responsibilities with respect thereto under applicable law.
If there is no successor Securities Depository appointed by the Issuer, the
Trustee shall authenticate and deliver Bonds to the beneficial owners thereof.
The Issuer may determine not to continue participation in the system of book
entry transfers through DTC (or a successor Securities Depository) at any time
by giving reasonable written notice to DTC (or a successor Securities
Depository) and the Trustee.  In such event, the Issuer shall execute and
deliver to the Trustee, and the Trustee shall authenticate and deliver the
Bonds to the beneficial owners thereof.

     Section 2.12. Payments to Cede & Co.; Payments to Beneficial Owners.

     (a) Notwithstanding any other provision of this Indenture to the contrary,
so long as any Bond is registered in the name of Cede & Co., as nominee of DTC,
all payments with respect to principal of, premium, if any, Purchase Price, and
interest on, such Bond and all notices with respect to such Bond shall be made
and given, respectively, pursuant to DTC's rules and procedures.

     (b) Payments by the DTC Participants to beneficial owners will be governed
by standing instructions and customary practices, as is now the case with
municipal securities held for the accounts of customers in bearer form or
registered in "street  name," and will be the responsibility of such DTC
Participant and not of DTC, the Trustee or the Issuer, subject to any statutory
and regulatory requirements as may be in effect from time to time.


                                  ARTICLE III

                            INTEREST RATES ON BONDS

     Section 3.01. Interest Rate.  All Bonds shall accrue interest at Daily
Rates on the date of original issuance and thereafter at Daily Rates unless and
until the Rate Period for the Bonds is converted to a different Rate Period
pursuant to Section 3.03.  Notwithstanding anything to the contrary in this
Article, in no event 




                                      18
<PAGE>   24

shall the cumulative amount of interest paid or payable on the Bonds exceed the
"net interest cost" which will produce a "net effective interest rate" equal to
the maximum rate permitted by Virginia law.
        
     Section 3.02. Determination of Interest Rates.

             (a)  Determination by Remarketing Agent.

                       (i)  The Interest Rate shall be determined by the 
             Remarketing Agent as the rate of interest which, in the judgment of
             the Remarketing Agent, would cause the Bonds to have a market value
             as of the date of determination equal to the principal amount
             thereof, taking into account prevailing market conditions; provided
             that so long as a Letter of Credit is in place, the interest rate
             borne by the Bonds shall not exceed the maximum interest rate with
             respect to the Bonds specified in the Letter of Credit.  With
             respect to Flexible Rates, the Remarketing Agent shall determine
             the Flexible Rate and the Flexible Rate Period for each Bond at
             such rate and for such period as it deems advisable in order to
             minimize the net interest cost on the Bonds, taking into account
             prevailing market conditions.
        
                       (ii)   In the event the Remarketing Agent fails for any 
             reason to determine or notify the Trustee of the Interest Rate for
             any Interest Rate Period:
        
                              (A) The Interest Rate then in effect for Bonds 
                       that accrue interest at Daily Rates will remain in effect
                       from day to day until the Trustee is notified of a new
                       Daily Rate determined by the Remarketing Agent.
        
                              (B) The Interest Rate then in effect for Bonds 
                       that accrue interest at Weekly Rates will remain in
                       effect from week to week until the Trustee is notified of
                       a new Weekly Rate determined by the Remarketing Agent.
        
                              (C) The Interest Rate for any Bond that accrues 
                       interest at Flexible Rates and for which a Flexible Rate
                       and Flexible Rate Period is not determined shall be equal
                       to the PSA Municipal Index and the Interest Rate Period
                       for such Bond shall extend through the day preceding the
                       next Business Day, until the Trustee is notified of a new
                       Flexible Rate and Flexible Rate Period determined for
                       such Bond by the Remarketing Agent.
        
                              (D) The Interest Rate then in effect for Bonds 
                       that accrue interest at the Term Rate will be
                       automatically converted to Flexible Rates with Flexible
                       Rate Periods beginning on each Business Day and extending
                       through the day preceding the next Business Day until the
                       Trustee is notified of a new Flexible Rate and Flexible
                       Rate Period determined for such Bond by the Remarketing
                       Agent.
        
                       (iii)  All determinations of Interest Rates pursuant to 
             this Section shall be conclusive and binding upon the Issuer, the
             Company, the Trustee and the Owners of the Bonds to which such
             rates are applicable.
        


                                      19
<PAGE>   25

                       (iv) The Interest Rate in effect for Bonds during any 
             Interest Rate Period shall be available to Owners between 1:00 p.m.
             and 5:00 p.m., New York City time on any Business Day, from the
             Remarketing Agent or the Trustee at their principal offices.
        
             (b)  Flexible Rates.  (i) The Flexible Rate Period for each Bond 
shall be of such duration, not exceeding 270 days, as may be offered by the
Remarketing Agent and specified by the purchaser; provided that if a Letter of
Credit is then in effect and such Letter of Credit provides less than 275 days'
interest coverage, such period shall not be longer than a period equal to the
maximum number of days' interest coverage provided by such Letter of Credit
minus 5 days or the Trustee shall not authenticate any Bond for a Flexible Rate
Period at a Flexible Rate providing an amount of interest which, when added to
the aggregate interest to accrue on all outstanding Flexible Rate Bonds, would
exceed the maximum amount available under the Letter of Credit for the payment
of interest minus an amount equal to 5 days' maximum interest coverage on all
Flexible Rate Bonds.  Any Bond may accrue interest at a Flexible Rate for a
Flexible Rate Period different from any other Bond.  Each Flexible Rate Period
shall commence on a Business Day and end on a day immediately preceding a
Business Day.  The Remarketing Agent shall offer and accept purchase commitments
for the Bonds for such Flexible Rate Periods and at such Flexible Rates as it
deems to be advisable in order to minimize the net interest cost on the Bonds
taking into account prevailing market conditions; provided, however, that the
foregoing shall not prohibit the Remarketing Agent from accepting purchase
commitments for longer Flexible Rate Periods (and at higher Flexible Rates) than
are otherwise available at the time of any remarketing if the Remarketing Agent
determines that, taking into account prevailing market conditions, a lower net
interest cost on the Bonds can be achieved over the longer Flexible Rate 
Period.  Notwithstanding the foregoing, no Flexible Rate Period may be
established which exceeds 270 days (or such lower number as is permitted above)
or, if the Remarketing Agent has given or received notice of any conversion to
a Daily, Weekly or Term Rate Period, the remaining number of days prior to the
Conversion Date, and if a Letter of Credit is then in effect, no Flexible Rate
Period may be established which extends beyond the remaining term of such
Letter of Credit minus 5 days.
        
                       (ii) Each Flexible Rate and Flexible Rate Period
             shall be determined not later than 1:00 p.m., New York City time,
             on the First Business Day of the Flexible Rate Period to which it
             relates and provided to the Trustee by the Remarketing Agent by

     received, prior to the date on which notice of conversion is required to be
     given to Registered Owners, written confirmation from the Remarketing Agent
     that it has not established and will not establish any Flexible Rate 
     Periods extending beyond the day before the Conversion Date;

duration, are subject to mandatory tender for purchase on the Conversion Date
at a Purchase Price equal to the principal amount thereof plus accrued
interest; provided that the Purchase Price for Bonds converted from a Term Rate
Period on a date when such Bonds are also subject to optional redemption at a
premium shall include an amount equal to the premium that would be payable if
such Bonds were redeemed on such date.

     (c) Prior to Expiration of Letter of Credit.  The Bonds are subject to
mandatory tender for purchase on the Interest Payment Date next preceding the

Payment Date the Trustee has received notice that the Letter of Credit has been
or will be extended or an Alternate Letter of Credit will be provided pursuant
to Section 7.01, at a Purchase Price equal to the principal amount thereof plus

     (a) Remarketing of Tendered Bonds.  Unless otherwise instructed by the
Company, the Remarketing Agent shall offer for sale and use its best efforts to
find purchasers for all Bonds or portions thereof for which notice of tender
has been received pursuant to Section 4.01(c) or which are subject to mandatory
tender.  While the Bonds are in book-entry only form, the Remarketing Agent
will make payment of the Purchase Price for tendered Bonds in accordance with
the procedures established by DTC.  If the book-entry only system is not in
effect, the terms of any sale by the Remarketing Agent shall provide for the

City time, on the purchase date, in the case of Bonds accruing interest at
Flexible Rates, (ii) in immediately available funds at or before 4:00 p.m., New
York City time, on the purchase date, in the case of Bonds accruing interest at
Daily Rates or Weekly Rates, and (iii) in clearinghouse funds at or before
12:00 noon, New York City time, on the purchase date, in the case of Bonds
accruing interest at Term Rates.  The Remarketing Agent shall not sell any Bond
as to which a notice of conversion from one type of Rate Period to another has
been given by the Trustee unless the Remarketing Agent has advised the Person
to whom the sale is made of the conversion.

     (b) Purchase of Tendered Bonds.

         (i) Notice.  At or before 3:00 p.m., New York City time, on the 
     Business Day immediately preceding the date fixed for purchase of tendered
     Bonds (or 12:45 p.m., New York City time, on the purchase date in the case
     of Bonds accruing interest at Daily or Flexible Rates), the Remarketing
     Agent shall give notice by telephone, telegram, telecopy, telex,
     Electronically or by other similar communication to the Trustee of the
     principal amount of tendered Bonds which were remarketed and the amounts
     that will be transferred pursuant to Section 4.03(a).  Not later than 4:00
     p.m. (or 1:00 p.m., in the case of Bonds accruing interest at Daily or
     Flexible Rates), New York City time, on the date of receipt of such notice
     the Trustee shall give notice by telephone, telegram, telecopy,
     Electronically or by other similar communication to the Bank and the
     Company, specifying
        



                                      25
<PAGE>   31

the principal amount of tendered Bonds as to which the Remarketing Agent has not
found a purchaser at that time.  At or before 3:00 p.m., New York City time, on
the Business Day prior to the purchase date to the extent known to the
Remarketing Agent, but in any event, no later than 11:00 a.m. (or 1:00 p.m., in
the case of Bonds accruing interest at Daily, Weekly or Flexible Rates), New
York City time, on the date fixed for purchase, (or two Business Days prior to
the date fixed for purchase in the event tendered Bonds accrue interest at Term
Rates), the Remarketing Agent shall give notice to the Trustee by telephone
(promptly confirmed in writing or Electronically) of the names, addresses and
taxpayer identification numbers of the purchasers, the denominations of Bonds to
be delivered to each purchaser and, if available, payment instructions for
regularly scheduled interest payments, or of any changes in any such information
previously communicated.
                
       (ii)  Sources of Payments; Drawings on Letter of Credit.  The Remarketing
Agent shall cause to be paid to the Trustee on the date fixed for purchase of
tendered Bonds, all amounts representing proceeds of the remarketing of such
Bonds, such payments to be made in the manner and at the time specified in
subsection 4.03(a) above.  If such amounts will not be sufficient to pay the
principal amount thereof plus the accrued and unpaid interest thereon (if any)
to the purchase date, the Trustee shall by 1:15 p.m., New York City time, on the
purchase date draw under the Letter of Credit, if any, then held by the Trustee
in accordance with its terms in a manner so as to furnish immediately available
funds by 3:00 p.m., New York City time on such purchase date, in an amount
sufficient, together with the remarketing proceeds available for such purchase,
to enable the Trustee to pay the purchase price of Bonds to be purchased on such
purchase date.  If no Letter of Credit is then held by the Trustee, the Company
shall deliver or cause to be delivered to the Trustee (A) immediately available
funds in an amount equal to such deficiency prior to 2:30 p.m., New York City
time, on the date set for purchase of tendered Bonds accruing interest at Daily
Rates and Weekly Rates (3:00 p.m., New York City time, in the case of Flexible
Rate Bonds), and (B) clearinghouse funds in an amount equal to such deficiency
prior to 12:15 p.m., New York City time, on the date set for purchase of
tendered Bonds accruing interest at Term Rates (the obligation of the Company to
deliver such moneys not being conditioned on receipt by the Company of the
foregoing notice from the Trustee).  All monies received by the Trustee as
remarketing proceeds or from drawings on the Letter of Credit and additional
amounts, if any, received from the Company shall be deposited by the Trustee in
the appropriate account of the Bond Purchase Fund to be used solely for the
payment of the Purchase Price of tendered Bonds and shall not be commingled with
other funds held by the Trustee.
        
       (iii) Payments by the Trustee.  At or before 3:00 p.m., New York City
time, on the date set for purchase of tendered Bonds and upon receipt by the
Trustee of 100% of the aggregate Purchase Price of the tendered Bonds, the
Trustee shall pay or receipt the Purchase Price of such Bonds to the Registered
Owners thereof.  Such payments shall be made in immediately available funds (or
by wire transfer), unless the Bonds to be purchased accrue interest at Term
Rates, in which event such payments shall be made in clearinghouse funds.  The
Trustee shall apply in order (A) monies paid to it by the Remarketing Agent as
proceeds of the remarketing of such Bonds by the Remarketing Agent (which monies
shall not include any monies of the Issuer, the Company or any guarantors
thereof), (B) proceeds of a drawing of the Letter of Credit, and (C) other
monies made available by the Company.  If sufficient funds are not available for
the purchase of all tendered Bonds, no purchases shall be consummated, all as
further set forth in Section 4.04 hereof.

       (iv)  Registration and Delivery of Tendered or Purchased Bonds.  On the
date of purchase, the Trustee shall register and deliver (or hold) or cancel all
Bonds purchased on any purchase date as follows:  (A) Bonds purchased or
remarketed by the Remarketing Agent shall be registered and made available to
the Remarketing Agent by 2:15 p.m., New York City time, in accordance with the
instructions of the Remarketing Agent; (B) Bonds purchased with proceeds of a
drawing on the Letter of Credit shall be held as Pledged Bonds in accordance
with subparagraph (v) below; and (C) Bonds purchased with amounts provided by
the Company shall be registered in the name of the Company and shall be held in
trust by the Trustee on behalf of the Company and shall not be released from
such trust unless the Trustee shall have received written instructions from the
Company.  Notwithstanding anything herein to the contrary, so long as the Bonds
are held under the book-entry only system in accordance with Section 2.11
hereof, Bonds will not be delivered as set forth above; rather, transfers of
beneficial ownership of the Bonds to the person indicated above will be effected
on the registration books of DTC pursuant to its rules and procedures.
        
       (v)   Pledged Bonds.  Bonds purchased with proceeds of a drawing on the
Letter of Credit pursuant to this Section shall constitute "Pledged Bonds" and
shall be held by the Trustee as agent for the Bank as pledgee of the Company
pursuant to the Reimbursement Agreement (and shall be shown as such on the
registration books maintained by the Trustee) unless and until (1) the Trustee 
has written confirmation from the Bank to the extent contemplated by the terms
of the Letter of Credit that the Letter of Credit has been reinstated with
respect to such drawing and (2) the Bank has notified the Trustee by telephone
(thereafter promptly confirmed in writing) that such Bonds have been released
from the pledge pursuant to the Reimbursement Agreement and are no longer
Pledged Bonds.  Pending reinstatement of the Letter of Credit and release of
such pledge as aforesaid, the Bank shall be entitled to receive all payments of
principal of and interest on Pledged Bonds as pledgee of the Company and such
Bonds shall not be transferable or deliverable to any party (including the
Company) except the Bank pursuant to the Reimbursement Agreement.  The
Remarketing Agent shall, at the request of the Bank, continue to use its best
efforts to arrange for the sale of any Pledged Bonds, subject to full
reinstatement of the Letter of Credit with respect to the drawings with which
such Bonds were purchased, at a price equal to the principal amount thereof plus
accrued interest.
        
       Notwithstanding anything to the contrary in this subsection, if and for
so long as the Bonds are to be registered in accordance with Section 2.11
hereof, the registration requirements under this subsection (v) shall be deemed
satisfied if Pledged Bonds are (1) registered in the name of the Securities
Depository or its nominee in accordance with Section 2.11 hereof, (2) credited
on the books of the Securities Depository to the account of the Trustee (or its
nominee) and (3) further credited on the books of the Trustee (or such nominee)
to the account of the Bank (or its designee).
        
       (vi)  Resale of Bonds Purchased by the Company.  In the event that any
Bonds are registered to the Company pursuant to subparagraph (iv) above to the
extent requested by the Company, the Remarketing Agent shall offer for sale and
use its best efforts to sell such Bonds at a price equal to the principal amount
thereof plus accrued interest.
        
       (vii) Delivery of Tendered Bonds; Effect of Failure to Surrender Bonds.
All Bonds to be purchased on any date shall be required to be delivered to the
principal office of the Trustee at or before (A) 1:00 p.m., New York City time,
on the purchase date in the case of Bonds accruing interest at Flexible or Daily
Rates; (B) 12:00 noon, New York City time, on the purchase date in the case of
Bonds accruing interest at Weekly Rates; or (C) 5:00 p.m., New York City time,
on the second 
        


                                      27

     Business Day prior to the purchase date in the case of Bonds accruing
     interest at Term Rates, except for Bonds delivered by or on behalf of an
     Investment Company in accordance with Section 4.05 hereof which may be
     delivered by 3:00 p.m., New York City time, on the purchase date.  If the
     Owner of any Bond (or portion thereof) in certificated form that is subject
     to optional or mandatory purchase pursuant to this Article fails to deliver
     such Bond to the Trustee for purchase on the purchase date, and if the
     Trustee is in receipt of the Purchase Price therefor, such Bond (or portion
     thereof) shall nevertheless be deemed purchased on the day fixed for
     purchase thereof and ownership of such Bond (or portion thereof) shall be
     transferred to the purchaser thereof as provided in subsection (e)(iv)
     above. Any Owner who fails to deliver such Bond for purchase shall have no
     further rights thereunder except the right to receive the Purchase Price
     thereof upon presentation and surrender of said Bond to the Trustee.  The
     Trustee shall, as to any tendered Bonds which have not been delivered to it
     (i) promptly notify the Remarketing Agent of such nondelivery and (ii)
     place a stop transfer against an appropriate amount of Bonds registered in
     the name of such Registered Owner(s) on the bond registration books.  The
     Trustee shall place such stop(s) commencing with the lowest serial number
     Bond registered in the name of such Registered Owner(s) until stop
     transfers have been placed against an appropriate amount of Bonds until the
     appropriate tendered Bonds are delivered to the Trustee.  Upon such
     delivery, the Trustee shall make any necessary adjustments to the bond
     registration books.
        
     Section 4.04. Inadequate Funds for Tenders.  If the funds available for
purchases of Bonds pursuant to this Article IV are inadequate for the purchase
of all Bonds tendered on any purchase date, the Trustee shall, after any
applicable grace period:  (a) return all tendered Bonds to the Registered
Owners thereof; (b) return all moneys received for the purchase of such Bonds 
to the Persons providing such monies; and (c) notify the Issuer and the
Remarketing Agent of the return of such Bonds and moneys and the failure to make
payment for tendered Bonds.
        
     Section 4.05. Tenders by Investment Companies.  The Owner of any Bond
issued hereunder that is an Investment Company, or is holding Bonds on behalf
of an Investment Company, may, at its option, notify the Remarketing Agent and
the Trustee of such fact in writing and in such notice irrevocably elect to
have its Bond(s) purchased on the next date on which such Bond(s) may be
purchased pursuant to Section 4.01 hereof.  Any notice delivered by an
Investment Company with respect to its Bond(s) shall contain the information
required under Section 4.01(b) hereof and shall be irrevocable with the same
effect described in Section 4.01(b)(iii).

     Section 4.06. Bond Purchase Fund.  There is hereby created with the
Trustee a segregated trust fund to be designated the "Bond Purchase Fund".  The
Bond Purchase Fund shall consist of three sub-accounts to be designated
respectively the "Remarketing Account", the "Letter of Credit Purchase Account"
and the "Company Purchase Account".

     The Trustee shall deposit or cause to be deposited into the Remarketing
Account, when and as received, all moneys delivered to the Trustee as and for
the Purchase Price of remarketed Bonds by or on behalf of the Remarketing
Agent.  The Trustee shall disburse moneys from the Remarketing Account to pay
the Purchase Price of Bonds properly tendered for purchase upon surrender of
such Bonds.

     The Trustee shall deposit or cause to be deposited into the Letter of
Credit Purchase Account, when and as received, all proceeds from a drawing on
the Letter of Credit pursuant to Section 4.03(b).  The Trustee shall disburse
moneys from the Letter of Credit Purchase Account to pay the Purchase Price of
Bonds properly 



                                      28
<PAGE>   34

tendered for purchase upon surrender of such Bonds; provided that such proceeds
shall not be applied to purchase Pledged Bonds or Company Bonds.
        
     The Trustee shall deposit or cause to be deposited into the Company
Purchase Account, when and as received, all moneys delivered to the Trustee by
or for the account of the Company pursuant to the Agreement.  The Trustee shall
disburse moneys from the Company Purchase Account to pay the Purchase Price of
Bonds properly tendered for purchase by or on behalf of the Company upon
surrender of such Bonds or to reimburse the Bank for drawing under the Letter
of Credit for such purpose.

     The funds held by the Trustee in the Bond Purchase Fund shall not be
considered Pledged Revenues as that term is defined herein and shall not
constitute part of the trust estate which is subject to the lien of this
Indenture.  The moneys in the Bond Purchase Fund shall be used solely to pay
the Purchase Price of Bonds as aforesaid (or to reimburse the Bank for drawings
under the Letter of Credit for such purpose) and may not be used for any other
purposes.  It shall be the duty of the Trustee to hold the moneys in the Bond
Purchase Fund, without liability for interest thereon, for the benefit of the
Registered Owners of Bonds which have been properly tendered for purchase or
deemed tendered on the purchase date, and if sufficient funds to pay the
Purchase Price for such tendered Bonds shall be held by the Trustee in the Bond
Purchase Fund for the benefit of the Registered Owners thereof, each such
Registered Owner shall thereafter be restricted exclusively to the Bond
Purchase Fund for any claim of whatever nature on such Registered Owner's part
under this Indenture or on, or with respect to, such tendered Bond.  The
provisions of Section 6.03 hereof shall govern any funds held in the Bond
Purchase Fund for such Registered Owners of the Bonds which remain unclaimed
for a period of two years after the applicable purchase date.

                            DEPOSIT OF BOND PROCEEDS

     Section 5.01. Deposit of Proceeds of Bonds.  The initial proceeds of the
Bonds and the other amounts delivered to the Trustee pursuant to Section 2.01
hereof shall be deposited by the Trustee as follows:

             (a) in the Debt Service Fund, established pursuant to Section 6.01
     hereof, a sum equal to the accrued interest, if any, paid by the initial
     purchasers of the Bonds, and

             (b) in a separate escrow account established outside of this 
     Indenture with PNC Bank, N.A. in accordance with the escrow agreement dated
     the Issue Date (the "Escrow Agreement") between PNC Bank, N.A. and the
     Company, the balance of the proceeds received from the initial purchasers
     of the Bonds (such proceeds to be used in connection with the redemption of
     the 1987 Bonds on or before November 13, 1997).

                       DEBT SERVICE FUND AND REBATE FUND

     Section 6.01. Establishment of Certain Funds and Accounts.  The Issuer
hereby establishes with the Trustee the Debt Service Fund, within which there
is hereby established a Company Debt Service Account and a Letter of Credit
Debt Service Account and the Rebate Fund.

     Section 6.02. Debt Service Fund.  The Trustee shall maintain the Debt
Service Fund as follows:

             (a)   The Trustee shall deposit into the Company Debt Service 
     Account all amounts received by the Trustee or for the account of the
     Company pursuant to Section 5.01(a) hereof and all Debt Service Payments
     received pursuant to the Agreement.
        
             (b)   The Trustee shall deposit into the Letter of Credit Debt 
     Service Account all moneys received by the Trustee from drawings under the
     Letter of Credit to pay principal of, premium, if any, on and interest on
     the Bonds.
        
             (c)   Moneys in the Letter of Credit Debt Service Account shall be
     applied to the payment when due of principal of, premium, if any, on and
     interest on the Bonds (other than Pledged Bonds or Company Bonds).
        
             (d)   Moneys in the Company Debt Service Account shall be applied 
     to the following in the order of priority indicated:

                   (1) the reimbursement of the Bank when due for moneys drawn 
             under the Letter of Credit and deposited in the Letter of Credit
             Debt Service Account for payment of principal of, premium, if any,
             on and interest on the Bonds;
        
                   (2) when insufficient moneys have been received under the 
             Letter of Credit for application pursuant to Subsection 6.02(c),
             the payment when due of principal of, premium, if any, on and
             interest on the Bonds, other than Company Bonds or Pledged Bonds;
        
                   (3) the payment when due of principal of, premium, if any, 
             on and interest on Pledged Bonds; and
        
                   (4) the payment when due of principal of, premium, if any, 
             on and interest on Company Bonds, provided that if the Trustee
             shall have received written notice from the Bank that any amounts
             are due and owing to the Bank under the Reimbursement Agreement,
             such payments shall be made to the Bank for the account of the
             Company.
        
             (e) By 12:00 noon on the Business day immediately preceding each
     Interest Payment Date, each redemption date and the maturity date of the
     Bonds, the Trustee shall present the requisite draft and certificate for a
     drawing on the letter of Credit so as to comply with the provisions of the
     Letter of Credit for payment to be made in sufficient time for the Trustee
     to receive the proceeds of such drawing at or before 10:00 a.m. on such
     Interest Payment Date, redemption date or maturity date, as the case may
     be, to pay principal of, premium, if any, on and interest on the Bonds due
     on such 
        


                                      30
<PAGE>   36

     date.  In addition, the Trustee shall draw on the Letter of Credit pursuant
     to its terms in accordance with and in order to satisfy the requirements of
     Section 11.02(b).  By 5:00 p.m. on each date it presents the requisite
     documents for a drawing on the Letter of Credit, the Trustee shall give
     notice to the Company by telephone, promptly confirmed in writing, of the
     amount so drawn. The Trustee shall promptly notify the Company by oral or
     telephonic communication confirmed in writing if the Bank fails to transfer
     funds in accordance with the Letter of Credit upon the presentment of the
     requisite draft and certificate.  In calculating the amount to be drawn on
     the Letter of Credit for the payment of principal of and interest on the
     Bonds, whether on an Interest Payment Date, at maturity or upon redemption
     or acceleration, the Trustee shall not take into account the potential
     receipt of funds from the Company under the Agreement on such Interest
     Payment Date, or the existence of any other moneys in the Bond Fund, but
     shall draw on the Letter of Credit for the full amount of principal and
     interest coming due on the Bonds.
        
     Section 6.03. Return of Monies from Non-Delivery of Bonds.  In the event
any Bond shall not be delivered for payment when the principal thereof becomes
due, either at maturity, at the date fixed for redemption thereof, or
otherwise, and is not thereafter delivered for payment, or if interest thereon
is unclaimed, any funds which shall be held for such purpose by the Trustee and
which remain unclaimed by the Registered Owner of the Bond for a period of two
years after such due date thereof, shall, upon request in writing by the
Company, and subject to applicable unclaimed property or similar laws of the
State, be paid to the Company for the benefit of the Registered Owner thereof
free of any trust or lien and thereafter the Registered Owner of such Bond
shall look only to the Company for payment without any interest thereon, and
the Trustee shall not have any further responsibility with respect to such
moneys.  In addition, if at any time after there are no longer any Bonds
Outstanding the Trustee determines that the amounts on deposit in the Funds and
accounts created under this Indenture are in excess of the amounts necessary to
pay the Bond Obligations, the Trustee shall pay such excess to the Bank, to the
extent of any amount certified by the Bank as due from the Company under the
Reimbursement Agreement, and then to the Company as an overpayment of the Debt
Service Payments free of any trust or lien.

     Section 6.04. Rebate Fund; Covenants Regarding Rebate.

     (a) Upon written notice from the Company, the Trustee shall establish a
Rebate Fund in accordance with the provisions of this Section 6.04.  Such Fund
shall be for the sole benefit of the United States of America and shall not be
subject to the claim of any other Person, including without limitation the
Registered Owners.  The Rebate Fund is established for the purpose of complying
with Section 148 of the Code and the Regulations promulgated pursuant thereto.
The money deposited in the Rebate Fund, together with all investments thereof
and investment income therefrom, shall be held in trust and applied solely as
provided in this Section.  The Rebate Fund is not a portion of the Trust Estate
and is not subject to the lien of this Indenture.

     (b)  At the close of each Bond Year, the Company, or its agent, shall
compute the amount of "Excess Earnings," if any, for the period beginning on
the Issue Date and ending at the close of such Bond Year, transmit a copy of
such computation to the Trustee, and pay to the Trustee for deposit to the
Rebate Fund an amount equal to the difference, if any, between the amount then
in the Rebate Fund and the "Excess Earnings" so computed.  If, at the close of
any Bond Year, the amount in the Rebate Fund exceeds the amount that would be
required to be paid to the United States of America under paragraph (d) below
if the Bonds had been paid in full, such excess may be transferred from the
Rebate Fund and paid to the Company to be used for such purposes for which, or
to be redeposited to such fund from which, such amounts were originally
intended.



                                      31
<PAGE>   37

     (c)  In general, "Excess Earnings" for any period of time means the sum of

              (i)  the excess of --

                        (A)  the aggregate amount earned during such period of 
              time on all Nonpurpose Investments (including gains on the
              disposition of such obligations) in which Gross Proceeds of the
              Bonds are invested (other than amounts attributable to an excess  
              described in this subparagraph (c)(i)), over
        
                        (B)  the amount that would have been earned during such
              period of time if the Yield on such Nonpurpose Investments (other
              than amounts attributable to an excess described in this
              subparagraph (c)(i)) had been equal to the Yield on the Bonds,
              plus
        
              (ii)  any income during such period of time attributable to the 
     excess described in subparagraph (c)(i) above.
        
     (d)  The Trustee shall pay to the United States of America at least once
every five years an amount, as determined by the Company and provided in
writing to the Trustee, that ensures that at least 90 percent of the Excess
Earnings from the Issue Date to the close of the period for which the payment
is being made will have been paid.  The Trustee shall pay to the United States
of America not later than 60 days after the Bonds have been paid in full 100
percent of the amount, as determined by the Company and provided in writing to
the Trustee, then required to be paid under Section 148(f) of the Code as a
result of Excess Earnings.  The Company shall provide to the Trustee any
completed Internal Revenue Service form that must accompany each payment to the
United States of America.

     (e)  The amounts to be computed, paid, deposited or disbursed under this
section shall be determined by the Company acting on behalf of the Issuer
within ten days after each successive anniversary date of the Issue Date of
each issue or series of Bonds.  By such date, the Company shall also notify, in
writing, the Trustee and the Issuer of the determinations the Company has made
and the payment to be made pursuant to the provisions of this section.  Upon
written request of any Registered Owner of Bonds, the Company shall furnish to
such Registered Owner of Bonds a certificate (supported by reasonable
documentation, which may include calculation by Bond Counsel or by some other
service organization) showing compliance with this section and other applicable
provisions of Section 148 of the Code.

     (f)  Notwithstanding anything contained herein to the contrary, the
provisions of this section shall not apply to the Trustee, the Issuer or the
Company if (i) within 180 days from the Issue Date, all Gross Proceeds are
expended to finance the Project or (ii) the proceeds of the Bonds including any
investment earnings thereon, have been applied in a manner which, in the
written opinion of Bond Counsel delivered to the Trustee, will not adversely
affect the tax-exempt status of interest on the Bonds.

     (g)  The Trustee shall maintain a record of the periodic determinations by
the Company of the tentative Rebate Amount for a period beginning on the first
anniversary date of the Issue Date and ending on the date six years after the
final retirement of the Bonds.  Such records provided by the Company shall
state each such anniversary date and summarize the manner in which the
tentative Rebate Amount, if any, was determined.  This provision shall not be
applicable if the Gross Proceeds are expended within 180 days of the Issue Date
of the applicable series or issue of Bonds.



                                      32
<PAGE>   38

     (h)  If the Trustee shall declare the principal of the Bonds and the
interest accrued thereon immediately due and payable as the result of an Event
of Default specified in this Indenture, or if the Bonds are optionally or
mandatorily prepaid or redeemed prior to maturity as a whole in accordance with
their terms, any amount remaining in any of the funds shall be transferred to
the Rebate Fund to the extent that the amount therein is less than the
tentative Rebate Amount computed by the Company as of the date of such
acceleration or redemption, and the balance of such amount shall be used
immediately by the Trustee for the purpose of paying principal of, premium, if
any, and interest on the Bonds when due.  In furtherance of such intention, the
Issuer hereby authorizes and directs its officers and commissioners to execute
any documents, certificates or reports required by the Code and to make such
elections, on behalf of the Issuer, which may be permitted by the Code and
which are requested by either the Company or the Trustee, as are consistent
with the purpose for the issuance of the Bonds.

     (i)  If the Company fails to provide any of the information,
certifications, calculations or moneys to the Trustee as required in this
Section 6.04, neither the Trustee nor the Issuer shall have any obligation to,
and shall not, make any calculation required hereunder.

     Section 6.05. Intentionally Omitted.

     Section 6.06. Moneys to be Held for All Registered Owners, With Certain
Exceptions.  Until applied as herein provided, moneys and investments held in
all Funds and accounts established hereunder (other than funds held in the Bond
Purchase Fund and the Rebate Fund) shall be held in trust for the benefit of
the Registered Owners of all Outstanding Bonds, except that on and after the
date on which the interest on or principal or redemption price of any
particular Bond or Bonds is due and payable from the Debt Service Fund, the
unexpended balance of the amount deposited or reserved in such Fund for the
making of such payments shall, to the extent necessary therefor, be held for
the benefit of the Registered Owner or Registered Owners entitled thereto.

     Section 6.07. Additional Accounts and Subaccounts.  At the written request
of the Company, the Trustee shall establish and maintain additional accounts
within the Funds or subaccounts within the accounts established hereunder as
the Company may reasonably request; provided that (a) in each case, the written
request of the Company shall set forth in reasonable detail the sources of
deposits into and disbursements from the account or subaccount to be
established, (b) in each case, the sources of deposits into and disbursements
from the account or subaccount to be established shall be limited to the
sources of deposits permitted or required under this Indenture to be made into
and the disbursements permitted or required to be made from the fund or account
within which it is to be established, and (c) each additional account or
subaccount established hereunder shall be held in trust for the benefit of the
Registered Owners of all Outstanding Bonds, except as provided in Section 6.06
hereof.


                                  ARTICLE VII

                                LETTER OF CREDIT

     Section 7.01. Extension or Replacement in Anticipation of Expiration.  At
least 45 days (or such shorter period as shall be acceptable to the Trustee)
prior to the Interest Payment Date next preceding the Expiration Date of the
current Letter of Credit, the Company may provide for the delivery to the
Trustee of (1) an amendment to the Letter of Credit which extends the
Expiration Date to a date that is not earlier than 



                                      33
<PAGE>   39

one year from its then current Expiration Date (provided, however, that
notwithstanding anything herein to the contrary, the Letter of Credit initially
delivered under this Indenture may be extended, in the manner otherwise provided
for herein, for successive periods of not less than 90 days) or (2) an Alternate
Letter of Credit issued by a national banking association, a bank, a trust
company or other financial institution or credit provider, which shall have
terms which are the same in all material respects (except Expiration Date and
except any changes pursuant to this Indenture with respect to interest or
premium coverage in connection with a concurrent interest rate reset or
conversion) as the current Letter of Credit and which shall have an Expiration
Date that is not earlier than one year from the Expiration Date of the Letter of
Credit then in effect.  The institution issuing the Alternate Letter of Credit
must be such as to maintain a rating on the Bonds equal to or higher than the
then current rating on the Bonds given by the Rating Service, and the Trustee
shall have received, on or before the date of delivery of the Alternate Letter
of Credit, written notice from the Rating Service that the issuance of the
Alternate Letter of Credit and substitution thereof for the then current Letter
of Credit will result in a rating on the Bonds equal to or higher than the then
current rating on the Bonds.  The Trustee shall not accept an Alternate Letter
of Credit under this Section unless there shall have been delivered to the
Trustee (1) a written notice from the Rating Service as provided in the
immediately preceding sentence, (2) an opinion of counsel to the Bank
satisfactory to the Trustee with respect to the validity, binding effect and
enforceability of such Alternate Letter of Credit and (3) an opinion of Bond
Counsel to the effect that such action will not adversely affect the exclusion
from gross income of interest on the Bonds for federal income tax purposes.  If
the Letter of Credit is so extended or if an Alternate Letter of Credit
complying with the requirements of this Section is so provided, the mandatory
tender for purchase pursuant to clause (c) of Section 4.02, shall not occur. 
Unless all of the conditions of this Section which are required to be met 45
days (or such shorter period as shall be acceptable to the Trustee) preceding
the Interest Payment Date next preceding the Expiration Date of the Letter of
Credit have been satisfied, the Trustee shall take all action necessary to call
the Bonds for mandatory tender for purchase pursuant to clause (c) of Section
4.02 on the Interest Payment Date next preceding such Expiration Date; provided
that if the Company shall have notified the Trustee in writing that it expects
to meet all the conditions for the delivery of an amendment extending the
existing Letter of Credit, or the delivery of an Alternate Letter of Credit from
a bank identified in such notice, meeting all of the requirements of this
Section on or before the Interest Payment Date next preceding the Expiration
Date of the existing Letter of Credit, then the notice of mandatory tender for
purchase pursuant to the clause (c) of Section 4.02 shall state that it is
subject to rescission, and the Trustee shall rescind such notice, if such
conditions are so met (in which case such mandatory purchase shall not occur).
The provisions of this Section with respect to the substitution of an Alternate
Letter of Credit in the event that the Expiration Date of the Letter of Credit
is not extended shall apply equally to the substitution of another Alternate
Letter of Credit in the event that the Expiration Date of an existing Alternate
Letter of Credit is not extended.

     Section 7.02. Other Replacement.  The delivery of an Alternate Letter of
Credit in anticipation of the expiration of current Letter of Credit shall be
governed by Section 7.01.  Otherwise, if at any time, when the Bonds are
subject to optional purchase pursuant to Section 4.01, the Company shall
provide for the delivery to the Trustee of (1) an Alternative Letter of Credit
which shall have terms which are the same in all material respects (except as
to Expiration Date and except any changes pursuant to this Indenture with
respect to interest or premium coverage in connection with a concurrent
interest rate reset or conversion) as the current Letter of Credit, which shall
have an Expiration Date that is not less than one year from the date of its
delivery and not sooner than the Expiration Date of the current Letter of
Credit then in effect and which shall be issued by a national banking
association, a bank, a trust company or other financial institution or credit
provider, (2) an opinion of counsel to the Bank satisfactory to the Trustee
with respect to the validity, binding effect and enforceability of such
Alternate Letter of Credit, and (3) an opinion of Bond Counsel to the effect
that such action will not adversely affect the exclusion from gross income of
interest on the Bonds for federal income 



                                      34
<PAGE>   40

tax purposes, and if the requirements set forth in this Section are met, then
the Trustee shall accept such Alternate Letter of Credit and promptly surrender
for cancellation the previously held Letter of Credit to the issuer thereof in
accordance with the terms of such Letter of Credit.  The institution issuing the
Alternate Letter of Credit must be such as to maintain a rating on the Bonds
equal to or higher than the then current rating on the Bonds given by the Rating
Service.  The replacement of the Letter of Credit by the Alternate Letter of
Credit must not, by itself, adversely affect the current rating or ratings on
the Bonds, and the absence of such an adverse effect shall be evidenced in
writing by the Rating Service to the Trustee at or prior to such replacement.
        
     Section 7.03. Notice to Holders.  The Trustee shall give notice to the
Registered Owners, in the name of the Issuer, of the proposed replacement of
the current Letter of Credit with an Alternate Letter of Credit, by first class
mail, postage prepaid, not less than 30 days prior to the interest Payment Date
next preceding the proposed replacement date.

     Section 7.04. Reduction.  In each case that Bonds are redeemed or deemed
to have been paid pursuant to Article XVI, the Trustee shall take such action
as may be permitted under the Letter of Credit to reduce the amount available
thereunder to an amount equal to the principal amount of the outstanding Bonds,
plus interest for the maximum period between Interest Payment Dates plus 15
days; provided that such action by the Trustee shall not be required if the
Letter of Credit so reduces automatically pursuant to its terms.  Upon
reduction of the amount available under the Letter of Credit pursuant to the
terms of the Letter of Credit and this Section as a result of redemption of
Bonds, the Bank shall have the right, at its option, to require the Trustee to
promptly surrender the outstanding Letter of Credit to the Bank and to accept
in substitution therefor a substitute Letter of Credit in the same form, dated
the date of such substitution, for an amount equal to the amount available
under the Letter of Credit as so reduced, but otherwise having terms identical
to the then outstanding Letter of Credit.

     Section 7.05. Other Credit Enhancement; No Credit Enhancement.  After a
mandatory purchase of the Bonds pursuant to clause (c) of Section 4.02, nothing
in this Article VII shall limit the Company's right to provide other credit
enhancement (such as a letter of credit not meeting the requirement of this
Article VII or bond insurance) or no credit enhancement as security for the
Bonds; provided that any such credit enhancement shall have administrative
provisions reasonably satisfactory to the Trustee and the Company shall have 
furnished to the Trustee with respect thereto an opinion of Bond Counsel to the
effect such action will not adversely effect the exclusion from gross income of
interest on the Bonds for federal income tax purposes.


                                  ARTICLE VIII

                                  INVESTMENTS

     Section 8.01. Investment of Funds.    (a)  Pending disbursement of the
amounts on deposit in any Fund, the Trustee is hereby directed to invest and
reinvest such amounts (other than amounts held pursuant to Section 6.03 and
amounts held in the Bond Purchase Fund or in the Letter of Credit Debt Service
Account, which shall be held uninvested) in Investment Securities promptly upon
receipt of, and, subject to the limitations set forth in this Article, in
accordance with, the written instructions of the Company executed by an
Authorized Company Representative, which instructions shall specify particular
investments and shall certify that such investments constitute Investment
Securities.  All such investments shall be credited to the Fund from which the
money used to acquire such investments shall have come, and all income and
profits on 



                                      35
<PAGE>   41

such investments shall be credited to, and all losses thereon shall be charged
against, such Fund.  As amounts invested are needed for disbursement from any
Fund, the Trustee on receipt of written instruction from the Company shall cause
a sufficient amount of the investments credited to that Fund to be redeemed or
sold and converted into cash to the credit of that Fund.  The Trustee shall not
be liable or responsible for any loss resulting from any such investment or
reinvestment as herein authorized or for its inability, after reasonable effort
and within a reasonable time, to make such investment or reinvestment; except
that the Trustee shall be liable for any loss resulting from its willful or
negligent failure, within a reasonable time after receiving the direction from
the Company to make any investment or reinvestment in the manner provided for
herein at the Company's direction.
        
     (b)  Any investment made in accordance with this Indenture may (i) be
executed by the Trustee or the Issuer with or through the Trustee or its
affiliates, and (ii) be made in securities of any entity for which the Trustee
or any of its affiliates serves as distributor, advisor or other service
provider.  If the Company does not give directions as to investment of money
held by the Trustee, or if an Event of Default has occurred and is continuing
hereunder, the Trustee shall make such investments in Investment Securities as
are permitted under applicable law and as it deems advisable.  The Trustee
shall be permitted to charge to the Company its standard fees and all expenses
in connection with any services performed in accordance with this Section 8.01.

     (c)  The Company by its execution of the Agreement covenants to restrict
the investment of money in the Funds created under this Indenture in such
manner and to such extent, if any, as may be necessary, after taking into
account reasonable expectations at the time the Bonds are delivered to their
original purchasers, so that the Bonds will not constitute arbitrage bonds
under Section 148 of the Code and the Regulations, and the Trustee hereby
agrees to comply with the Company's written instructions executed by an
Authorized Company Representative with respect to the investment of money in
the Funds created under this Indenture.  It is expressly provided that, because
investments hereunder are to be made by the Trustee pursuant to instructions of
the Company, the Trustee shall have no liability with respect thereto if, as a
result of an investment made pursuant to such instructions, the Bonds become
"arbitrage bonds" within the meaning of Section 148 of the Code.

     Section 8.02. Covenants Regarding Tax Exemption.  The Issuer covenants to
refrain from taking any action which would adversely affect, and to take such
action as is reasonable and available and within its control to ensure, the
treatment of the Bonds as obligations described in Section 103 of the Code (or
Section 1312 of the Tax Reform Act of 1986), the interest on which is not
includable in the "gross income" of the holder (other than the income of a
"substantial user" of the Project or a "related person" within the meaning of
Section 147(a) of the Code) for purposes of federal income taxation.  In
particular, but not by way of limitation thereof, the Issuer, based solely upon
representations and covenants of the Company, covenants as follows:

             (a)  to refrain from taking any action that would result in the 
     Bonds being "federally guaranteed" within the meaning of Section 149(b) of
     the Code;
        
             (b)  to refrain from using any portion of the proceeds of the 
     Bonds, directly or indirectly, to acquire investment property or to replace
     funds which were used, directly or indirectly, to acquire investment
     property (as defined in Section 148(b)(2) of the Code) which produces a
     yield over the term of the Bonds that is materially higher (as defined in
     the Regulations) than the yield on the Bonds, other than investment
     property acquired with --
        


                                      36
<PAGE>   42

                  (1) proceeds of the Bonds invested for a reasonable temporary 
             period of three years of less, or until such proceeds are needed
             for the purpose for which the Bonds are issued,
        
                  (2) amounts invested in a bona fide debt service fund, within
             the meaning of Section 1.103-13(b)(12) of the Treasury Regulations,
             and
        
                  (3) amounts deposited in any reasonably required reserve or
             replacement fund to the extent such amounts do not exceed ten
             percent of the proceeds of the Bonds and to the extent that at no
             time during any Bond Year will the aggregate amount so invested
             exceed 150 percent of debt service on the Bonds for such year;
        
             (c) to otherwise restrict the use of proceeds of the Bonds or 
     amounts treated as proceeds of the Bonds, as may be necessary, to satisfy
     the requirements of Section 148 of the Code (relating to arbitrage);
        
             (d) to use no more than two percent of the proceeds from the sale 
     of the Bonds for the payment of Costs of Issuance; and

             (e) to use no portion of the proceeds of the Bonds to provide any
     airplane, skybox or other private luxury box, health club facility, 
     facility to be used for gambling, or store the principal business of which
     is the sale of alcoholic beverages for consumption off premises.
        
It is the understanding of the Issuer and the Trustee that the covenants
contained herein are intended to assure compliance with the Code and any
regulations or rulings promulgated by the U.S. Department of the Treasury
pursuant thereto.  In the event that regulations or rulings are hereafter
promulgated which modify or expand provisions of the Code, as applicable to the
Bonds, the Issuer will not be required to comply with any covenant contained
herein to the extent that such modification or expansion, in the opinion of
Bond Counsel, will cause noncompliance with such covenant to not adversely
affect the exemption from federal income taxation of interest on the Bonds
under the Code.  In the event that regulations or rulings are hereafter
promulgated which impose additional requirements which are applicable to the
Bonds, the Issuer agrees to comply with the additional requirements to the 
extent necessary, in the opinion of Bond Counsel, to preserve the exemption 
from federal income taxation of interest on the Bonds under Section 103 of the 
Code.

     It is expressly provided that, because investments hereunder are to be
made by the Trustee pursuant to instructions of the Company, the Issuer shall
have no liability with respect thereto if, as a result of an investment made
pursuant to such instructions, the Bonds become "arbitrage bonds" within the
meaning of Section 148 of the Code.  Furthermore, it is expressly provided
that, because the Company will instruct the Trustee as to the disposition of
the gross proceeds of the Bonds and moneys in the Project Fund and the Rebate
Fund, neither the Trustee nor the Issuer shall have any liability with respect
thereto if, as a result of dispositions made pursuant to such instructions, or
not made due to a lack of such instructions, there is a breach of the Issuer's
covenants contained herein.

     Company, from funds available for such purpose in the Debt Service Fund, as
     follows:
        
                   (i)   If the Bonds accrue interest at Flexible, Daily or

             any Interest Payment Date at an Optional Redemption price equal to
             100% of the principal amount thereof, together with accrued
             interest to the redemption date.
        
                   (ii)  If the Bonds accrue interest at a Term Rate, the Bonds
             shall be subject to Optional Redemption (i) at any time on and
             after the dates and at the Optional Redemption prices set forth
             below, together with accrued interest, if any, to the redemption

     The optional redemption dates and redemption prices set forth above may be
changed by a supplemental indenture approved by the Company and the Issuer and
filed with the Trustee, provided that any such supplemental indenture shall be
accompanied by a Favorable Opinion of Bond Counsel.

     If a Letter of Credit is then in effect and the redemption price includes
any premium, the right of the Company to direct an optional redemption is
subject to the condition that the Trustee has received, prior to the date on
which notice of redemption is required to be given to Registered Owners,
written confirmation from the Bank that it can draw under the Letter of Credit
on the proposed redemption date in an aggregate amount sufficient to cover the
principal of and premium and interest due on the redemption date.

              (b) Special Mandatory Redemption.

              The Bonds shall be subject to special mandatory redemption prior 
     to maturity on a date selected by the Company not later than 180 days after
     the occurrence of a Determination of Taxability at a redemption price equal
     to 100% of the principal amount thereof, plus accrued interest to the
     redemption date.  Any such special mandatory redemption shall be in whole
     unless it is finally determined as evidenced by an opinion of Bond Counsel
     delivered to and addressed to the Trustee that the interest on an amount
     less than all the Bonds (which amount shall be set forth in such opinion)
     is so includable in the gross income of Owners, in which case only such
     amount need be redeemed.

              If the Trustee receives written notice from any Owner or 
     Registered Owner stating that (i) the Owner or Registered Owner has been
     notified in writing by the Internal Revenue Service that it proposes to
     include the interest on any Bond in the gross income of such Owner or
     Registered Owner for the reasons stated in the definition of "Determination
     of Taxability" set forth herein or any other proceeding has been instituted
     against such Owner or Registered Owner which may lead to a Final
     Determination as described in the aforesaid definition, and (ii) such Owner
     or Registered Owner will afford the Company the opportunity to contest the
     same, either directly or in the name of the Owner or Registered Owner, and
     until a conclusion of any appellate review, if sought, then the Trustee
     shall promptly give notice thereof to the Company and the Issuer and to the
     Owner or Registered Owners of Bonds then Outstanding.  If a Final
     Determination thereafter occurs, the Trustee shall make demand for
     prepayment of the unpaid Debt Service Payments or necessary portions
     thereof from the Company and give notice of the special mandatory
     redemption of the appropriate amount of Bonds on the date selected by the
     Company within the required period of 180 days.  In taking any action or
     making any determination under this Section 9.01(b), the Trustee may rely
     on an opinion of counsel.
        
              (c) Extraordinary Optional Redemption.

              The Bonds will be subject to extraordinary optional redemption by
     the Issuer, at the direction of the Company, in whole or in part, at a
     redemption price of 100% of the principal amount thereof plus accrued
     interest to the redemption date on any date within one year of the
     occurrence of any of the following events:
        
                  (a) The Plant shall have been damaged or destroyed to such 
              extent that, in the opinion of the Company, (i) normal operations
              at the Plant are prevented or are likely to be prevented for a
              period of four consecutive months, or (ii) the restoration of the
              Plant is not economically feasible.
        


                                      39
<PAGE>   45

                      (b) Title to, or the temporary use of, all or substantial
             all of the Plant shall have been under the exercise of the power
             of eminent domain by any governmental authority or person, firm or
             corporation acting under governmental authority which, in the
             opinion of the Company, is likely to result in normal operations
             at the Plant being prevented for a period of four consecutive
             months.
        
                      (c) Changes, which the Company cannot reasonably control 
             or overcome, in the economic availability of materials, supplies,
             labor, equipment and other properties and things necessary for the
             efficient operation of the Plant shall have occurred, or
             technological or other changes shall have occurred which, in the
             opinion of the Company, render uneconomic the continued design,
             acquisition, construction, installation or operation of the Plant.
        
                      (d) Any court or administrative body shall enter a 
             judgment, order or decree requiring cessation of all or any
             substantial part of operations at the Plant, to such an extent
             that, in the opinion of the Company, normal operations at the
             Plant are likely to be prevented for a period of four consecutive
             months.
        
                      (e) As a result of any changes in the Virginia 
             Constitution or the Constitution of the United States of America
             or as a result of legislation or administrative action (whether
             state or federal) or by final decree, judgment or order of any
             court or administrative body (whether state or federal) entered
             after the contest thereof by the Company in good faith, the
             Agreement shall have become void or unenforceable or impossible of
             performance in accordance with the intent and purposes of the
             parties, or shall have been declared to be unlawful, or
             unreasonable burdens or excessive liabilities shall have been
             imposed on the Issuer or the Company, including without limitation
             federal, state or other ad valorem, property, income or other
             taxes not being imposed on the date of the Agreement.
        
     Section 9.02. Selection of Bonds for Redemption.  In the event that fewer
than all Bonds subject to redemption are to be redeemed, Bonds shall be
selected for redemption in the following manner provided that the Bonds that
remain outstanding shall be in authorized denominations:

             (a)  In the case of any Optional, Extraordinary Optional or Special
     Mandatory Redemption, Bonds shall be selected for redemption (i) by DTC,
     in accordance with its rules and procedures, so long as DTC or its nominee
     is the sole Registered Owner of the Bonds, or (ii) by the Trustee by lot,
     first, from Bonds subject to such redemption (other than Bonds owned of
     record by the Company), and, second, from Bonds subject to such redemption
     owned of record by the Company.
        
             (b) In the case of Bonds of varying denominations, the Trustee 
     shall treat each Bond as representing that number of Bonds which is
     obtained by dividing the face amount thereof by the smallest authorized
     denomination.
        
     Section 9.03. Notice of Redemption.  (a)  The Company shall deliver notice
to the Trustee and the Bank of its intention to prepay the Debt Service
Payments and cause the Bonds to be called for Optional Redemption or
Extraordinary Optional Redemption at least 25 days prior to the proposed
redemption date of Daily Rate and Weekly Rate Bonds, and at least 45 days prior
to the proposed redemption date of Flexible Rate and Term Rate Bonds.  The
Trustee shall cause notice of any redemption of Bonds hereunder, which notice
shall be prepared by the Company, to be mailed by first class mail, postage
prepaid (except when DTC is the 



                                     40
<PAGE>   46

Registered Owner of all of the Bonds and except for persons or entities owning
or providing evidence of ownership satisfactory to the Trustee of a legal or
beneficial ownership in at least $1,000,000 of principal amount of Bonds who so
request, in which cases, by certified mail, return receipt requested), to the
Registered Owners of all Bonds to be redeemed at the registered addresses
appearing in the registration books kept for such purpose pursuant to Article
II hereof.  Each such notice shall (i) be mailed at least 15 days prior to the
redemption date for Daily, Weekly and Flexible Rate Bonds and at least 30 days
prior to the redemption date for Term Rate Bonds, (ii) identify the Bonds to be
redeemed if less than all Bonds are to be redeemed (specifying the CUSIP
numbers, if any, assigned to the Bonds), (iii) specify the redemption date and
the redemption price, and (iv) state that on the redemption date the Bonds
called for redemption will be payable at the principal office of the Trustee,
that from that date interest will cease to accrue and that no representation is
made as to the accuracy or correctness of the CUSIP numbers printed therein or
on the Bonds; provided, however, that so long as DTC or its nominee is the sole
Registered Owner of the Bonds under the Book-Entry Only System, redemption
notices will be sent to Cede & Co.  Any failure on the part of DTC, or a DTC
Participant to give such notice to the Owner or any defect therein shall not
affect the sufficiency or validity of any proceedings for the redemption of the
Bonds.  No defect affecting any Bond, whether in the notice of redemption or
mailing thereof (including any failure to mail such notice), shall affect the
validity of the redemption proceedings for any other Bonds.
        
     (b) Conditional Notice.  If at the time of mailing of notice of an
Optional Redemption there shall not have been deposited with the Trustee moneys
sufficient to redeem all the Bonds called for redemption, such notice may state
that it is conditional, that is, subject to the deposit with the Trustee on or
prior to the redemption date of moneys sufficient to pay the redemption price
of the Bonds to be redeemed plus interest accrued thereon to the date of
redemption, and such notice shall be of no effect unless such moneys are so
deposited.

     (c)  Additional Notice of Redemption.  In addition to the redemption
notice required above, if there is more than one Registered Owner of the Bonds,
further notice (the "Additional Notice") shall be given by the Trustee as set
out below.  No defect in the Additional Notice nor any failure to give all or
any portion of the Additional Notice shall in any manner defeat the
effectiveness of a call for redemption if notice is given as prescribed in
paragraph (a) above.

              (1)  Each Additional Notice shall contain the information 
     required in paragraph (a) above for an official notice of redemption plus
     (i) the date of the Bonds as originally issued; (ii) the interest rate
     determination method for, or the rate of interest borne by each Bond being
     redeemed; (iii) the maturity date of each Bond being redeemed; and (iv)
     any other descriptive information needed to identify accurately the Bonds
     being redeemed.
        
              (2)  Each Additional Notice shall be published one time in a 
     financial newspaper or journal which regularly carries notices of
     redemption of other obligations similar to the Bonds, such publication to
     be made at least 30 days (15 days in the case of Bonds accruing interest
     at Daily, Weekly or Flexible Rates) prior to the date fixed for
     redemption.
        
              (3)  Each Additional Notice shall be sent at least 30 days (15 
     days in the case of Bonds accruing interest at Daily, Weekly or Flexible
     Rates) before the redemption date by registered or certified mail or
     overnight delivery service to the following registered securities
     depositories: Depository Trust Company of New York, New York, Midwest
     Securities Trust Company of Chicago, Illinois and Philadelphia Depository
     Trust Company of Philadelphia, Pennsylvania and to such other

     registered securities depositories as may be specified by the Company to
     the Trustee in writing and to one or more national information services
     that disseminate notices of redemption of obligations such as the Bonds as
     shall be specified by the Company to the Trustee in writing.
        
             (4)   The Trustee's agreement to give the notices specified in this
     subsection (c) is made as a matter of courtesy and accommodation only and
     the Trustee shall incur no liability to any Person for its failure to give
     such notices.
        
     (d)  CUSIP Identification.  Upon the payment of the redemption price of
the Bonds being redeemed, each check or other transfer of funds issued for such
purpose shall bear the CUSIP number identifying, by issue and maturity, the
Bonds being redeemed with the proceeds of such check or other transfer,
provided that neither the Issuer, the Company, nor the Trustee shall be deemed
to have made any representation as to the correctness of such CUSIP number.

     Section 9.04.  Effect of Redemption.  If payment of the redemption price of
the Bonds has been duly provided for on the redemption date, then interest on
the Bonds called for redemption will cease to accrue on such date, and the
Registered Owners will have no rights with respect to such Bonds nor will they
be entitled to the benefits of the Indenture except to receive payment of the
redemption price thereof and unpaid interest accrued to the date fixed for
redemption.

     Section 9.05.  Optional Redemption only at Direction of Company.  Optional
redemption of the Bonds by the Issuer pursuant to Sections 9.01(a) and (c)
shall only be made at the direction and in the sole discretion of the Company,
and the Issuer shall take no action with respect to Sections 9.01(a) or (c)
without the prior written direction of the Company.

     event of a filing of an involuntary case in bankruptcy under the United

     applicable law concerning bankruptcy, insolvency or reorganization against
     the Company such petition or proceeding shall remain undismissed or
     unstayed for a period of 90 days; or
        
             (iii)  failure by the Company to observe or perform any covenant,

     requesting that it be remedied and stating that such notice is a "Notice
     of Default" hereunder, is given to the Company by the Trustee or to the
     Company and the Trustee by the Issuer; provided, however, that if the
     default is such that it cannot be remedied within such period, it shall
     not constitute an Event of Default if the default, in the judgment of the
     Trustee in reliance upon advice of counsel, is correctable without
     material adverse effect on the Bonds and if corrective action is
     instituted by the Company within such period and is being diligently
     pursued until the default is remedied; or
        
             (iv)  failure by the Issuer to observe or perform any covenant,

           (v)    receipt by the Trustee of a written notice from the Bank
     stating that an Event of Default has occurred under the Reimbursement

     Credit will not be reinstated with respect to such interest.

Agreement other than its payment obligations and its agreements to comply with
arbitrage and other tax covenants, the Company shall not be deemed in default
by reason of not carrying out said agreement or agreements or performing said
obligation or obligations during the continuance of such inability so long as
the Company shall make reasonable effort to remedy with all reasonable dispatch
the cause or causes preventing it from carrying out its agreements; provided,
that the settlement of strikes, lockouts and other industrial disturbances 
shall be entirely within the discretion of the Company, and the Company shall
not be required to make settlement of strikes, lockouts and other disturbances
by acceding to the demands of the opposing party or parties when such course is
in the judgment of the Company unfavorable to the Company.
        
     Section 11.02. Acceleration and Annulment Thereof.

     (a)   If any Event of Default has occurred and is continuing the Trustee
(with the written consent of the Bank if the Bank has not dishonored a drawing

Bank and the Company, declare the principal of all Bonds then Outstanding to be
immediately due and payable, and upon such declaration the said principal,
together with interest accrued thereon, shall become due and payable
immediately at the place of payment provided therein, anything in this
Indenture or in the Bonds to the contrary notwithstanding; provided, however,
that no such declaration shall be made if the Company cures such Event of
Default prior to the date of the declaration.

     (b)   Upon any such declaration hereunder, the Trustee shall immediately,
on the date of such declaration, draw upon the Letter of Credit to the full
extent permitted by the terms thereof (such drawing to include amounts in
respect of interest accruing on the Bonds through the date payment of such
drawing by the Bank is due).  Upon receipt by the Trustee of payment of the
full amount drawn on the Letter of Credit and provided sufficient moneys are
available in the Debt Service Fund to pay pursuant to Section 6.02 all sums
        

                                     44

due on the Bonds, (i) interest on the Bonds shall cease to accrue and (ii)
the Bank shall succeed to and be subrogated to the right, title and interest of

Bond Purchase Fund which are identified for the payment of the Bonds or of the
purchase price of undelivered Bonds and any funds held in the Rebate Fund) and
any other security held for the payment of the Bonds, all of which, upon
payment of any fees and expenses due and payable to the Trustee pursuant to the
Agreement or this Indenture, shall be assigned by the Trustee to the Bank.
        
     (c) If after the principal of the Bonds has been so declared to be due and
payable and before a judgment or decree for payment of the money due has been
obtained by the Trustee all arrears of interest upon the Bonds, together with
interest on unpaid principal and interest (to the extent permitted by law) at
the Late Payment Rate, are paid or caused to be paid, and the reasonable
charges of the Trustee and the Registered Owners, including reasonable
attorney's fees, are paid or caused to be paid, and all Events of Default,
other than the non-payment of principal due solely by such declaration, have
been cured or waived as provided in Section 11.13, then, and in every such
case, the Trustee shall at the direction of the Registered Owners of a majority
in principal amount of the Bonds then Outstanding annul such declaration and
its consequences and such annulment shall be binding upon the Trustee and upon
all Registered Owners of Bonds issued hereunder; provided that there shall be
no annulment of any declaration resulting from (1) any Event of Default
specified in Subsection 11.01 (v) or (vi) unless the Trustee has received the
prior written consent of the Bank and written notice from the Bank that the
Letter of Credit has been fully reinstated or (2) any Event of Default which
has resulted in a drawing under the Letter of Credit unless the Trustee has
received written notice from the Bank that the Letter of Credit has been fully
reinstated.  No such annulment shall extend to or affect any subsequent default
or impair any right or remedy consequent thereon.

     Section 11.03. Legal Proceedings by Trustee.  If any Event of Default has
occurred and is continuing, the Trustee in its discretion may, and upon the
written request of the Registered Owners of 25% or more in principal amount of
the Bonds then Outstanding and receipt of indemnity from the Registered Owners
to its satisfaction shall, in its own name;

     (a) By mandamus, or other suit, action or proceeding at law or in equity,
enforce all rights of the Registered Owners, including the right to require the
Issuer or the Company to carry out any agreements with, or for the benefit of,
the Registered Owners and to perform its duties under the Agreement or the Act;

     (b) Bring suit upon the Bonds; and

     (c) By action or suit in equity enjoin any acts or things which may be
unlawful or in violation of the rights of the Registered Owners.

     Section 11.04. Discontinuance of Proceedings by Trustee.  If any
proceeding taken by the Trustee on account of any default is discontinued or is
determined adversely to the Trustee, the Issuer, the Trustee, the Company and
the Registered Owners shall be restored to their former positions and rights
hereunder as though no such proceeding had been taken.

     Section 11.05. Registered Owners May Direct Proceedings.  The Registered
Owners of a majority in principal amount of the Bonds then Outstanding
hereunder shall have the right to direct the method and place of conducting all
remedial proceedings by the Trustee hereunder, provided that (i) such
directions shall not be otherwise than in accordance with law or the provisions
of this Indenture, (ii) the Trustee shall have the 


                                     45
<PAGE>   51

right to decline to follow any such direction which in the opinion of the
Trustee would be unjustly prejudicial to Registered Owners not parties to such
direction or which could involve the Trustee in personal liability, and (iii)
if a Letter of Credit is in effect and no default has occurred and is
continuing thereunder, then the Bank shall have the right to give such
direction in lieu of such Registered Owners.
        
     Section 11.06. Limitations on Actions by Registered Owners.  No Registered
Owners shall have any right to pursue any remedy hereunder unless (a) the
Trustee shall have been given written notice of an Event of Default by the
Registered Owners of at least 25% in principal amount of the Bonds then
Outstanding, (b) the Registered Owners of at least 25% in principal amount of
the Bonds then Outstanding shall have requested the Trustee, in writing, to
exercise the powers hereinabove granted or to pursue such remedy in its or
their name or names, (c) the Trustee shall have been offered indemnity
satisfactory to it against costs, expenses and liabilities, and (d) the Trustee
shall have failed to comply with such request within 60 days after receipt of
such notice, request and offer of indemnity.

     Section 11.07. Trustee May Enforce Rights Without Possession of Bonds.
All rights under this Indenture and the Bonds may be enforced by the Trustee
without the possession of any Bonds or the production thereof at the trial or
other proceedings relative thereto, and any proceeding instituted by the
Trustee shall be brought in its name for the ratable benefit of the Registered
Owners of the Bonds.

     Section 11.08. Remedies Not Exclusive.  Except as limited under Section
17.01 of this Indenture, no remedy herein conferred is intended to be exclusive
of any other remedy or remedies, and each remedy is in addition to every other
remedy given hereunder or now or hereafter existing at law or in equity or by
statute.

     Section 11.09. Delays and Omissions Not to Impair Rights.  No delay or
omission in respect of exercising any right or power accruing upon any default
shall impair such right or power or be a waiver of such default, and every
remedy given by this Article may be exercised from time to time and as often as
may be deemed expedient.

     Section 11.10. Application of Moneys in Event of Default.  If any Event of
Default has occurred and is continuing, any moneys on deposit in any Fund or
account established hereunder (except the Bond Purchase Fund and the Rebate
Fund) and any monies received by the Trustee under this Article X, shall,
subject to the provisions of Section 6.04(h) hereof, be applied in the
following order; provided, however, that all moneys received by the Trustee
pursuant to any drawing made upon the Letter of Credit pursuant to Section
11.02(b) shall be applied by the Trustee to and only to the payment of
principal of interest on the Bonds (other than Pledged Bonds and Bonds owned of
record by the Company):

             FIRST:  To the payment of the costs of the Trustee, including 
     counsel fees, and any disbursements of the Trustee with interest thereon,
     and its reasonable compensation and any indemnities owing to it;
        
             SECOND:  To the payment of all interest then due on Outstanding 
     Bonds or, if the amount available for the payment of interest is
     insufficient for such purpose, to the payment of interest ratably in
     accordance with the amount due in respect of each Bond (other than Bonds
     owned of record by the Company);
        
             THIRD:  To the payment of the outstanding principal amount of all 
     Bonds or, if the amount available for the payment of principal is

<PAGE>   52

     ratably in accordance with the amount due in respect of each Bond (other
     than Bonds owned of record by the Company); and
        
              FOURTH:  The surplus, if any, shall to the extent of any 
     unreimbursed drawing under the Letter of Credit, or other obligations
     owing to the Bank under the Reimbursement Agreement, be paid to the Bank,
     and any remaining amounts be paid to the Company or the person lawfully
     entitled to receive the same or as a court of competent jurisdiction may
     direct.
        
Funds on deposit in the Bond Purchase Fund shall be applied in accordance with
Section 4.06 hereof.

     Section 11.11. Trustee's Right to Receiver.  The Trustee shall be entitled
as a matter of right to the appointment of a receiver; and the Trustee, the
Registered Owners and any receiver so appointed shall have such rights and
powers and be subject to such limitations and restrictions as are permitted by
law.

     Section 11.12. Trustee and Registered Owners Entitled to All Remedies.  It
is the purpose of this Article to make available to the Trustee and Registered
Owners all lawful remedies; but should any remedy herein granted be held
unlawful, the Trustee and the Registered Owners shall nevertheless be entitled
to every other remedy provided by law.  It is further intended that, insofar as
lawfully possible, the provisions of this Article shall apply to and be binding
upon any trustee or receiver who may be appointed hereunder.

     Section 11.13. Waiver of Past Defaults.  The Registered Owners of not less
than a majority in principal amount of the Outstanding Bonds may, with the
written consent of the Bank, on behalf of the Registered Owners of all the
Bonds waive any past default hereunder and its consequences, except a default

              (1)  in the payment of the principal of, premium, if any, or 
     interest on, or the Purchase Price of, any Bond, or

              (2)  in respect of a covenant or provision hereof which under 
     Article XV cannot be modified or amended without the consent of the
     Registered Owner of each Outstanding Bond.
        
     Upon any such waiver, such default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured, for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.


                                  ARTICLE XII

                                  THE TRUSTEE

     Section 12.01. Certain Duties and Responsibilities of Trustee.

              (a) The Trustee accepts the trusts hereby created and agrees to 
     perform the duties herein required of it upon the terms and conditions
     hereof and hereby acknowledges receipt of an executed copy of the
     Agreement and agrees to perform the duties therein required of it upon the
     terms and conditions thereof.  The Trustee shall have the right, power and
     authority, at all times, to do all things not inconsistent with the
     express provisions of this Indenture which it may deem necessary or
     advisable in order to:  (i) enforce the provisions of this Indenture, (ii)
     take any action with respect to
        



                                     47
<PAGE>   53

any Event of Default, (iii) institute, appear in or defend any suit or other
proceeding with respect to an Event of Default, or (iv) protect the interests
of the Registered Owners of any Outstanding Bonds.  The Trustee shall be
responsible only for performing those duties of the Trustee specifically
provided for herein and no implied duties or liabilities shall be read into
this Indenture against the Trustee.  In addition to the duties set forth above
the Trustee shall:
        
          (i)   hold all sums delivered to it by the Company for the payment of
     principal, premium, if any, and interest on the Bonds in trust for the
     benefit of the Registered Owners until such sums shall be paid to such
     Registered Owners or otherwise disposed of as herein provided;

          (ii)  except as otherwise permitted hereby, hold all Bonds tendered to
     it hereunder in trust for the benefit of the respective Registered Owners
     until monies representing the purchase price of such Bonds shall have been
     delivered to or for the account of or to the order of such Registered
     Owners;

          (iii) hold all monies delivered to it hereunder for the purchase of
     Bonds in trust for the benefit of the Person or entity which shall have so
     delivered such monies until the Bonds purchased with such monies shall
     have been delivered to or for the account of such Person or until
     otherwise disposed of as provided herein; and

          (iv)  keep such books and records with respect to the Bonds as shall
     be consistent with prudent industry practice (including specifically the
     Bond registration books) at its principal office and make such books and
     records available for inspection by the parties hereto, the Company and
     the Remarketing Agent at all reasonable times.

     (b)  The permissive rights of the Trustee to do things enumerated in this
Indenture shall not be construed as a duty and, except as provided in the next
succeeding sentence in respect of the period during the continuance of an Event
of Default, the Trustee shall not be liable for any action reasonably taken or
omitted to be taken by it in good faith and reasonably believed by it to be
within the discretion or power conferred upon it hereby, or be responsible
other than for its own negligence or willful misconduct. In case an Event of
Default has occurred and is continuing of which the Trustee has been notified
as provided in Section 12.03(h) or of which it is deemed to have notice
pursuant to such Section, the Trustee shall exercise such of the rights and
powers vested in it by this Indenture, and use the same degree of care and
skill in their exercise, as a prudent man would exercise under the
circumstances in the conduct of his own affairs.
        
     (c)  The Trustee shall not be required to give any bond or surety in
respect of the execution of its rights and duties under this Indenture.

     (d)  No provision of this Indenture shall be construed to relieve the
Trustee from liability for its own negligent action, its own negligent failure
to act or its own willful misconduct, except that
        
          (i) this subsection shall not be construed to limit the effect of
     subsection (a) or (b) of this Section;



                                     48
<PAGE>   54

                        (ii)  the Trustee shall not be liable for any error of
                judgment made in good faith by its officers, unless it shall be
                proved that the Trustee was negligent in ascertaining the
                pertinent facts;

                        (iii) the Trustee shall not be liable with respect to
                any action taken or omitted to be taken by it in good faith in
                accordance with any direction of the Registered Owners of a
                majority in aggregate principal amount of the Outstanding Bonds 
                permitted to be given by them under this Indenture; and

                        (iv)  no provision of this Indenture shall require the
                Trustee to expend or risk its own funds or otherwise incur any
                financial liability in the performance of any of its duties
                hereunder, or in the exercise of any of its rights or powers,   
                if it shall have reasonable grounds for believing that
                repayment of such funds or adequate indemnity, satisfactory to
                the Trustee, against such risk or liability is not assured to
                it. 

                (e) Whether or not therein expressly so provided, every
         provision of this Indenture relating to the conduct or
         affecting the liability of or affording protection to the Trustee
         shall be subject to the provisions of this Section.
        
         Section 12.02. Notice if Default Occurs or Notice of Taxability Occurs.
Within 45 days after the occurrence of any default hereunder of which the
Trustee has been notified as provided in Section 12.03(h) or of which it is
deemed to have notice pursuant to such Section, the Trustee shall give to the
parties to the Financing Documents, the Remarketing Agent, the Bank and the 
Registered Owners notice of such default hereunder known to the Trustee, unless
such default shall have been cured or waived; provided, however, that, in the
case of a default of the character described in Section 11.01(a)(iii) or (iv),
the Trustee shall be protected in withholding such notice if and so long as the
Trustee in good faith determines that the withholding of such notice is in the
interest of the Registered Owners; and provided, further, that in the case of
any default of the character described in Section 11.01(a)(iii) or (iv) no such
notice to Registered Owners shall be given until at least 30 days after the
occurrence thereof.  For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default.  The Trustee shall also give to the parties to the Financing
Documents, the Bank and the Registered Owners notice of receipt by it of any
notification from the Internal Revenue Service that the interest on the Bonds
is, or may be, subject to federal income taxation.
        
         Section 12.03. Certain Rights of Trustee.  Except as otherwise
provided in Section 12.01:

                (a) the Trustee may rely and shall be protected in acting or 
         refraining from acting upon any resolution, certificate,

         hereunder in good faith and in reliance thereon;
        
                (e) the Trustee shall be under no obligation to exercise any of

         investigation into such facts or matters as it may see fit, and, if
         the Trustee shall determine to make such further inquiry or
         investigation, it shall be entitled, upon reasonable notice and during
         regular business hours, and subject further to the Issuer's and the
         Company's safety and confidentiality requirements, to examine the
         books, records and premises of the Issuer or the Company personally or
         by agent or attorney;
        
                (g) the Trustee may execute any of the trusts or powers
         hereunder or perform any duties hereunder either directly or
         indirectly or by or through agents or attorneys and the Trustee shall
         not be responsible for any misconduct or negligence on the part of any
         agent or attorney appointed with due care by it hereunder;
        
                (h) the Trustee shall not be required to take notice or be
         deemed to have notice of any default hereunder or under any
         Financing Document unless the Trustee shall be specifically notified

         any Owner of the Outstanding Bonds, and in the absence of such notice
         the Trustee may conclusively assume that there is no default;
         provided, however, that the Trustee shall be required to take and be
         deemed to have notice of its failure to receive the monies necessary
         to make payments when due of Debt Service and Purchase Price Payments;
        
                (i) except for information provided by the Trustee concerning

         Registered Owners, each representing less than a majority of 



                                     50

     the aggregate principal amount of the Bonds then outstanding, the Trustee,
     in its sole discretion, may determine what action, if any, shall be taken;
        
             (k)    except as otherwise expressly provided by the provisions of

     to those set out in this Article XI; and
        
             (m)    the Trustee shall not be required to give any bond or 
     surety  with respect to the performance of its duties or the exercise of
     its powers under this Indenture.
        
     Section 12.04. Not Responsible for Recitals or Issuance of Bonds, etc..
The recitals contained herein or in the Bonds, except the certificate of
authorization signed on behalf of the Trustee, shall be taken as the statements
of the Issuer, and the Trustee assumes no responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or any Financing Document, except that the Trustee represents that
said Indenture has been duly authorized, executed and delivered by the Trustee
and represents, based on advice of counsel, that the Indenture constitutes a
legal, valid and binding obligation of the Trustee in accordance with the terms
hereof, except as its enforceability may be subject to (i) the exercise of
judicial discretion in accordance with general equitable principles; and (ii)
applicable liquidation, conservatorship, receivership, bankruptcy, insolvency,
reorganization, moratorium, rearrangement and other laws applicable to national
banks or for the relief of debtors generally heretofore or hereafter enacted
to the extent that the same may be constitutionally applied.  Further, the
Trustee makes no representations as to the validity or sufficiency of the
Bonds.  The Trustee shall not be accountable for the use or application by the
Issuer or the Company of Bonds or, upon disbursement from the Funds created
herein, the proceeds thereof.

     The Trustee shall have no responsibility with respect to compliance by the
Issuer or the Company with (i) Section 148 of the Code or (ii) any covenant
contained in this Indenture or the Agreement regarding the yields on
investments, other than to comply with the specific provisions of this
Indenture and the Agreement and with specific written directions of the Company
or the Issuer as may be provided for in this Indenture or in the Agreement.
Notwithstanding anything elsewhere in this Indenture contained, the Trustee
shall have the right, but shall not be required, to demand, in respect of the
authentication of any Bonds, the withdrawal of any cash, the release of any
property, or any action whatsoever within the purview of this Indenture or the
Agreement, any showings, certificates, opinions, appraisals or other
information, or corporate action or evidence thereof, in addition to that by
the terms hereof or thereof required as a condition of such action which is
deemed desirable by the Trustee for the purpose of establishing the right of
the Issuer or the Company to the authentication of any Bonds, the withdrawal of
any cash, or the taking of any other action by the Trustee.

     Section 12.05. May Hold Bonds.  The Trustee or any other agent of the
Issuer or the Company, in its individual or any other capacity, may become the
owner of Bonds and may otherwise deal with the Issuer or the Company with the
same rights it would have if it were not Trustee or such other agent.

     Section 12.06. Money Held in Trust.  Except as provided in Section 6.07
hereof, all money held in the Debt Service Fund under any provision of this
Indenture shall be held in trust for the benefit of the Registered Owners but,
except as provided in Article XV of this Indenture, need not be segregated from
other funds held in trust under this Indenture by the Trustee, but shall be
segregated at all times from all funds of the Issuer or the Trustee not held by
the Trustee under this Indenture.  The Trustee shall be under no liability for
interest on any money received by it hereunder except as otherwise provided in
this Indenture.

     Section 12.07. Corporate Trustee Required; Eligibility.  There shall at
all times be a Trustee hereunder which shall be a corporation organized and

that is either a trust company or a bank, authorized under such laws to
exercise trust powers, having a combined capital, surplus and undivided profits
of at least $150,000,000, subject to supervision or examination by federal or
state authority.  If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising
or examining authority, then for the purpose of this Section, the combined
capital and surplus of such corporation shall be deemed to be its combined
capital and surplus as set forth in its most recent report of condition so
published.  If at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner
and with the effect hereinafter specified in this Article.

     Section 12.08. Resignation and Removal of Trustee; Appointment of
Successor.

             (a) No resignation or removal of the Trustee and no appointment of
     a successor Trustee pursuant to this Article shall become effective until
     the acceptance of appointment by the successor     Trustee under Section
     12.09 of this Indenture.
        
             (b) The Trustee may resign at any time by giving written notice 
     thereof to the Issuer, the Company, the Bank and the Remarketing Agent. 
     If an instrument of acceptance by a successor Trustee shall not have been
     delivered to the Trustee within 30 days after the giving of such notice of
     resignation, the resigning Trustee may petition any court of competent
     jurisdiction for the appointment of a successor Trustee.
        
             (c) The Trustee may be removed at any time by the Registered 
     Owners of a majority in aggregate principal amount of the Outstanding
     Bonds, by a written request for removal delivered to the Issuer, the
     Company, the Bank and the Remarketing Agent.
        
             (d) If at any time:

                 (i)  the Trustee shall cease to be eligible under Section 12.07
             of this Indenture or under applicable law and shall fail to resign
             after written request therefor by any party to a Financing
             Document or by a Registered Owner who has been a bona fide
             Registered Owner for at least six months, or
                
                 (ii) the Trustee shall become incapable of acting or shall be
             adjudged a bankrupt or insolvent or a receiver of the Trustee or
             of its property shall be appointed or any public officer shall
             take charge or control of the Trustee or of its property or
             affairs for the purpose of rehabilitation, conservation or
             liquidation,
        


                                     52
<PAGE>   58

     then, in any such case, (x) the Company or the Issuer may remove the
     Trustee, or (y) any Registered Owner who has been a bona fide Registered
     Owner for at least six months may, on behalf of himself and all others
     similarly situated, petition any court of competent jurisdiction for the
     removal of the Trustee and the appointment of a successor Trustee.
        
             (e) If the Trustee shall resign, be removed or become incapable of
     acting, or if a vacancy shall occur in the office of Trustee for any
     cause, the Issuer, with the prior consent of the Company, shall promptly
     appoint a successor Trustee.  If, within one year after the occurrence of
     such resignation, removal or incapability, or the occurrence of such
     vacancy, a successor Trustee shall be appointed by the Registered Owners
     of a majority in aggregate principal amount of the Outstanding Bonds and
     notice of acceptance of such appointment is delivered to the parties to
     the Financing Documents, the successor Trustee so appointed shall,
     forthwith upon its acceptance of such appointment, become the successor
     Trustee and supersede the successor Trustee appointed by the Issuer.  If
     no successor Trustee shall have been so appointed by the Issuer or the
     Registered Owners and accepted appointment in the manner hereinafter
     provided, any Registered Owner who has been a bona fide Registered Owner
     for at least six months may, on behalf of himself and all other Registered
     Owners similarly situated, petition any court of competent jurisdiction
     for the appointment of a successor Trustee.
        
             (f) The Issuer shall give notice of each resignation and each 
     removal of the Trustee and each appointment of a successor Trustee by
     causing to be mailed, at the expense of the Company, written notice of
     such event to the Registered Owners and to the parties to the Financing
     Documents and the Remarketing Agent.  Each notice shall include the name
     of the successor Trustee and the address of its principal office.
        
     Section 12.09. Acceptance of Appointment by Successor Trustee.  Every
successor Trustee appointed hereunder shall execute, acknowledge and deliver to
the Issuer, the Company, the Remarketing Agent and the retiring Trustee, an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee, 
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on request of
the Issuer or the successor Trustee, such retiring Trustee shall, upon payment
of its charges and expenses, execute and deliver an instrument transferring to
such successor Trustee all the rights, powers and trusts of the retiring
Trustee, and shall duly assign, transfer and deliver to such successor Trustee
all property and money held by such retiring Trustee hereunder.  Upon request
of any such successor Trustee, the Issuer shall execute any and all instruments
for more fully and certainly vesting in and confirming to such successor
Trustee all such rights, powers and trusts.
        
     No successor Trustee shall accept its appointment unless at the time of
such acceptance such successor Trustee shall be eligible under this Article.

     Section 12.10. Merger, Conversion, Consolidation or Succession to
Business.  Any corporation into which the Trustee may be merged or converted or
with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.

     Section 12.11. Fees, Charges and Expenses of Trustee.  Pursuant to the
provisions of the Agreement, the Trustee shall be entitled to be paid by the
Company reasonable compensation for its services rendered hereunder and to
reimbursement for its actual out-of-pocket expenses (including reasonable fees
and expenses of its counsel and agents) necessarily incurred in connection
therewith.  The Company may, without creating a default hereunder, contest in
good faith the necessity for and the reasonableness of any such services and
expenses after making payment therefor.  As security for the performance of the
obligations of the Company to the Trustee under the Agreement, the Trustee
shall have a lien prior to the Bonds upon all property and funds held or
collected by the Trustee as such, except (other than as provided in Section
11.10 hereof) funds received from a drawing under the Letter of Credit or funds
held in trust for the payment of principal of, premium, if any, or interest on
or the Purchase Price of Bonds.

     Pursuant to the terms of the Agreement, the Company shall (i) pay the
Trustee reasonable compensation for its services hereunder, and also all its
reasonable expenses and disbursements, including reasonable compensation for
all attorneys and agents engaged by it, and (ii) indemnify the Trustee,
including its officers, directors, employees and agents, against any and all
liabilities which the Trustee or its agents may incur (including reasonable
attorneys fees and expenses) in the exercise and performance of its powers and
duties hereunder, except with respect to the willful misconduct or negligence
of the Trustee.

     Nothing in this Section shall be deemed to excuse the Trustee from its
obligation to perform its duties in accordance with Section 6.02 and Section
11.02 of this Indenture.

     Section 12.12. No Obligation to Review Reports.  The Trustee shall not
have any obligation to review any financial statement or report provided to the
Trustee by the Company or the Issuer pursuant to this Indenture or the
Financing Agreement.  Notwithstanding any provision of this Indenture to the
contrary, the Trustee shall not be deemed to have notice of any item contained
in any such report or Event of Default which may be disclosed therein in any
manner.  The Trustee's sole responsibility with respect to such reports shall
be to act as the depository for such reports for the Registered Owners and to
make such reports available for review by the Registered Owners in accordance
with this Indenture.


                                  ARTICLE XIII

                                THE PAYING AGENT

     Section 13.01. The Paying Agent.  So long as the Bonds are Outstanding,
the Trustee shall serve as Paying Agent for the Bonds.

     Section 14.01. The Remarketing Agent.  The Issuer shall, at the direction
of the Company, appoint the Remarketing Agent for the Bonds, subject to the
conditions set forth in Section 14.02 hereof.  The Remarketing Agent shall
designate its principal office to the Trustee and signify its acceptance of the
duties and obligations imposed upon it hereunder by a written instrument of
acceptance delivered to the Issuer and the Trustee under which the Remarketing
Agent will agree to:



                                     54
<PAGE>   60

          (a) determine the Interest Rates and, with respect to Flexible Rates,
     Flexible Rate Periods, and give notice of such rates and periods in
     accordance with Article III hereof;
        
          (b) keep such books and records with respect to its duties as
     remarketing agent as shall be consistent with prudent industry practice;

          (c) use its best efforts to remarket Bonds in accordance with this
     Indenture; and

          (d) hold all moneys delivered to it hereunder for the purchase of 
     Bonds for the benefit of the person or entity which shall have so
     delivered such monies until the Bonds purchased with such monies shall
     have been delivered to or for the account of such person or entity.
        
     Section 14.02. Qualifications of Remarketing Agent.  The Remarketing Agent
shall have a capitalization of at least $100,000,000 and be authorized by law
to perform all the duties imposed upon it by this Indenture.  The Remarketing
Agent may at any time resign and be discharged of the duties and obligations
created by this Indenture by giving at least ten days' notice to the Issuer,
the Company, the Banks and the Trustee.  The Remarketing Agent may be removed
at any time at the direction of the Company, by an instrument filed with the
Remarketing Agent, the Issuer and the Trustee.

     In the event of the resignation or removal of the Remarketing Agent, the
Remarketing Agent shall pay over, assign and deliver any moneys and Bonds held
by it in such capacity to its successor or, if there is no successor, to the
Trustee.

     In the event that the Issuer shall fail to appoint a Remarketing Agent
hereunder, or in the event that the Remarketing Agent shall resign or be
removed, or be dissolved, or if the property or affairs of the Remarketing
Agent shall be taken under the control of any state or federal court or
administrative body because of bankruptcy or insolvency or for any other
reason, and the Issuer shall not have appointed a successor Remarketing Agent,
the Trustee, notwithstanding the provisions of the first paragraph of this
Section 14.02, shall ipso facto be deemed to be the Remarketing Agent for all
purposes of this Indenture until the appointment by the Issuer with the consent
of the Company of the Remarketing Agent or successor Remarketing Agent, as the
case may be; provided, however, that the Trustee, in its capacity as
Remarketing Agent, shall not be required to sell Bonds or determine the
Interest Rate on the Bonds or to perform the duties set forth in Section 3.02
hereof.

     not be inconsistent with this Indenture or to make any other provisions

     affect the interests of the Registered Owners; or
        
          (c) to provide or modify procedures permitting Registered Owners to
     utilize an uncertificated system of registration for Bonds; or

          (d) to modify, alter, amend, supplement or restate the Indenture in 
     any and all respects necessary, desirable or appropriate in connection
     with the delivery to the Trustee of a letter of credit, liquidity
     facility, standby bond purchase agreement or other security arrangement
     obtained or provided by the Company; or
        
          (e) to modify the provisions for optional redemption at the 
     commencement of a Term Rate; or

          (f) to modify, alter, amend, supplement or restate the Indenture in

     satisfy the requirements of any rating agency which may from time to time
     provide a rating on the Bonds, or in order to obtain or retain such rating
     on the Bonds as is deemed necessary by the Company and the Remarketing
     Agent; or
        
          (g) to provide for an Alternate Letter of Credit or any other credit
     enhancement permitted by the terms of this Indenture.

     Section 15.02. Amendments With Registered Owners' Consent.  This Indenture
may be amended from time to time by a Supplemental Indenture approved by the
Registered Owners of a majority in aggregate principal amount of the Bonds then
Outstanding; provided, that (a) no amendment shall be made which affects the
rights of some but less than all of the Registered Owners of the Outstanding
Bonds without the consent of the Registered Owners of a majority in aggregate
principal amount of the Bonds so affected, and (b) except as expressly
authorized hereunder, no amendment which alters the interest rates on any
Bonds, the maturity date, Interest Payment Dates, purchase upon tender or
redemption provisions of any Bonds, of this Article XV or which adversely
affects the security provisions hereunder may be made without the consent of
the Registered Owners of all Outstanding Bonds affected thereby.

     Section 15.03. Amendments to Agreement.  The Agreement may be amended by
written agreement of the Issuer and the Company, provided that no amendment may
be made which would adversely affect the rights of the Registered Owners
without the consent of the Registered Owners of a majority in aggregate
principal amount of the Bonds then Outstanding; provided further, that no such
amendment may be made which would adversely affect the rights of the Registered
Owners of some but less than all Outstanding Bonds without the consent of the
Registered Owners of a majority in aggregate principal amount of the Bonds so
affected; and no amendment may be made which would (i) decrease the amounts
payable under the Agreement; (ii) change the date of payment or prepayment
provisions under the Agreement; or (iii) change the amendment provisions of the
Agreement, in each case without the consent of all of the Registered Owners of
the Bonds adversely affected thereby, and provided further that the Agreement

consent of the Trustee in order to make conforming 



                                     56
<PAGE>   62

changes with respect to amendments made to this Indenture pursuant to Section

would adversely affect the interests of the Registered Owners and may consent
thereto with the consent of the owners of at least a majority in aggregate
principal amount of the Bonds then Outstanding which would be affected by the
action proposed to be taken; provided, that the Trustee shall not, without the
unanimous consent of the owners of all Bonds then Outstanding, consent to any
amendment which would (i) decrease the amount payable under the Letter of
Credit or (ii) reduce the term of the Letter of Credit.  Before the Trustee
shall consent to any amendment to the Letter of Credit, there shall have been
delivered to the Trustee an opinion of Bond Counsel that such amendment will
not adversely affect the exclusion from gross income of the interest on the
Bonds for federal income tax purposes and that such amendment is authorized by
the Indenture.

     Section 15.05. Other Matters Relating to Amendments and Supplements.  The
Trustee shall not be obligated to enter into or consent to any Supplemental
Indenture or any amendment to the Agreement or the Letter of Credit which
affects the rights, duties, liabilities and immunities of the Trustee under
this Indenture or otherwise.  Before the Issuer and the Trustee shall enter
into any Supplemental Indenture or before the Trustee shall consent to any
amendment to the Agreement or the Letter of Credit pursuant to this Article XV,
there shall have been delivered to the Trustee and the Issuer a Favorable
Opinion of Bond Counsel, including an opinion that such Supplemental Indenture
or amendment will, upon the execution and delivery thereof, be valid and
binding upon the Issuer, the Company or the Bank, as the case may be, in
accordance with its terms.  Upon the execution and delivery of any
Supplemental Indenture pursuant to the provisions of this Article XV, this
Indenture shall be, and be deemed to be, modified and amended in accordance
therewith, and the respective rights, duties and obligations under this
Indenture of the Issuer, the Trustee and all Registered Owners of the Bonds
then Outstanding shall thereafter be determined, exercised and enforced under
this Indenture subject in all respects to such modifications and amendments.
In addition, no amendment or supplement to the Indenture shall become effective
until signed by the Chairman of the Issuer or such other officer or
commissioner designated by the Issuer and until the Trustee has received the
written approval of such instrument from the Authorized Company Representative.
        
     Section 15.06. Consent of Bank.  Notwithstanding anything herein
contained, so long as a Letter of Credit is held by the Trustee, no supplement
or amendment shall be made to the Indenture or the Agreement without the prior
written consent of the Bank.


                                  ARTICLE XVI

                                   DEFEASANCE

     Section 16.01. Defeasance.  When interest on, and principal or redemption
price (as the case may be) of, and Purchase Price (if any) of all Bonds issued
hereunder have been paid, or there shall have been deposited with the Trustee
an amount, evidenced by moneys or non-callable Government Obligations the
principal of and interest on which, when due, will provide, sufficient moneys
to fully pay the Bonds at the earlier of the maturity date or date fixed for
redemption thereof or to any date upon which the Bonds could or must be
tendered for purchase, as well as all other sums payable hereunder by the
Issuer, the right, title and interest of the Trustee under the Indenture shall
thereupon cease and the Trustee, on demand of the Issuer at 


                                     57
<PAGE>   63

the request of the Company, shall release the lien of this Indenture and shall
execute such documents to evidence such release as may be reasonably required
by the Issuer and, after paying any remaining amounts owed to the Issuer (as
evidenced by a certificate of an Issuer Representative), the Trustee shall turn
over to the Bank such amount, if any, as is certified in writing by the Bank to
the Trustee to be owed to the Bank pursuant to the Reimbursement Agreement, and
then to the Company, the Issuer or such other person or body as may be entitled
to receive the same (as evidenced by a certificate of an Authorized Company
Representative) all balances remaining in any funds hereunder.  Notwithstanding
anything to the contrary contained herein, any defeasance and discharge
hereunder shall not be deemed to release the Trustee from its obligations
hereunder to register and transfer Bonds or to act as paying agent for the
Bonds until the date all the Bonds are scheduled to be paid.  In addition, such
defeasance shall not terminate the obligations of the Issuer under Section
8.02, the Company and the Trustee under Section 6.04, the Issuer, the Company
and the Trustee under Section 9.01(b) or the immunities and protections of the
Trustee hereunder.
        
     Section 16.02. Deposit of Funds for Payment of Bonds.

             (a) If there is deposited with the Trustee moneys or Government
     Obligations sufficient to pay the principal or redemption price of any
     particular Bond or Bonds becoming due, either at maturity or by call for
     redemption or otherwise (including a mandatory or optional tender for
     purchase), together with all interest accruing thereon to the due date,
     interest on the Bond or Bonds shall cease to accrue on such due date and
     all liability of the Issuer with respect to such Bond or Bonds shall
     likewise cease, except as provided in subsection (b) below; provided that
     the Trustee shall have received an opinion of Bond Counsel to the effect
     that such deposit will not adversely affect the exclusion from gross
     income of the interest on any of the Bonds or cause any of the Bonds to be
     classified as "arbitrage bonds" within the meaning of the Code; and
     provided, further, that if a Letter of Credit is then held by the Trustee,
     such payment and any payment of the purchase price of Bonds pursuant to
     Section 4.01 or 4.02, as applicable, shall be made only from proceeds of a
     drawing under the Letter of Credit deposited directly into the Letter of
     Credit Debt Service Account or the Letter of Credit Purchase Account,
     as applicable, or the Company shall have caused to be delivered to the
     Trustee and the Rating Service an opinion of nationally recognized counsel
     experienced in bankruptcy matters to the effect that any such payment and
     the payment of the purchase price of any Bonds pursuant to Section 4.01 or
     4.02 will not be considered an avoidable "preferential transfer" by the
     Company or the Issuer under Section 547 of the United States Bankruptcy
     Code in the event of a bankruptcy case under the United States Bankruptcy
     Code by the Issuer or by or against the Company or any Affiliate, as
     debtor.  Thereafter such Bond or Bonds shall be deemed not to be
     Outstanding hereunder and the Registered Owner or Registered Owners of
     such Bond or Bonds shall be restricted exclusively to the funds so
     deposited for any claim of whatsoever nature with respect to such Bond or
     Bonds, and the Trustee shall hold such funds in trust for such Registered
     Owner or Registered Owners.
        
             (b) Moneys deposited with the Trustee pursuant to Section 16.01 or
     16.02(a) hereof may be invested in Government Obligations maturing as
     provided in Section 16.01 or Section 16.02(a), and any such moneys and any
     moneys derived from any Government Obligations deposited under this
     Article XVI which remain unclaimed two years after the date payment
     thereof becomes due shall, upon written request of the Company, if the
     Company is not at the time to the knowledge of the Trustee (evidenced to
     the Trustee as provided in Section 12.03(h)) in default with respect to
     any covenant contained in the Financing Documents, be paid to the Company;
     and the Registered Owners of the Bonds for which the deposit was made
     shall thereafter be limited to a claim against the 
        

                                     58
<PAGE>   64

     Company; provided, however, that the Trustee, before making payment to the
     Company, may, at the expense of the Company, cause a notice to be
     published stating that the moneys remaining unclaimed will be returned to
     the Company after a specified date, such notice to be published in a
     newspaper or newspapers published at least once a day, six days a week,
     and generally circulated in the City of New York, New York.  All payments
     made hereunder shall be subject to all applicable unclaimed property or
     similar laws of the State.  Unclaimed moneys held under this Section shall
     not be invested.
        
             (c)  Following the deposit of moneys as provided in this Section 
     and Section 16.01 the current Interest Rate Period may not be converted to
     another Interest Rate Period and the Remarketing Agent shall not remarket
     any Bonds tendered for purchase.
        
             (d)  Deposits made with the Trustee in accordance with this 
     Section and Section 16.01 during any Daily Rate Period or Weekly Rate
     Period shall be accompanied by written evidence from each Rating Service
     then rating the Bonds that such deposit will not result in a withdrawal or
     reduction of the rating on the Bonds.
        

                                  ARTICLE XVII

                            MISCELLANEOUS PROVISIONS

recourse shall be had for any claim based on this Indenture or the Bonds
against any past, present or future Indemnified Party, either directly or

shall confer any right upon any person other than the parties hereto and the
Registered Owners of the Bonds.

     Section 17.03. Illegal, etc. Provisions Disregarded.  If any term or

corporate and a political subdivision under the laws of the Commonwealth of
Virginia, promises to pay to the registered owner named above, or registered

(as hereinafter  defined) to which interest has been paid or duly provided for,
or from the date of authentication hereof if such date is on an Interest
Payment Date to which interest has been paid or duly provided for, or from the
Issue Date specified above if no interest has been paid or duly provided for,
such payments of interest to be made on each Interest Payment Date until the
principal or redemption price hereof has been paid or duly provided for as

in immediately available funds or next day funds, depending on the applicable
Interest Rate Period (as defined below) and the instructions of the registered
owner upon presentation and surrender hereof at the principal office of PNC

Indenture dated as of August 1, 1997 (the "Indenture") securing the Series of

interest payment date on which such overdue interest shall be paid and a
special record date relating thereto.  This Bond is registered as to both
principal and interest on the registration books kept with the Trustee and may
be transferred or exchanged, subject to the further conditions specified in the

     Except as otherwise provided in the Indenture, this Bond shall not be
entitled to any right or benefit under the Indenture, or be valid or become
obligatory for any purpose, until this Bond shall have been authenticated by
execution by the Trustee of the certificate of authentication inscribed hereon.

                         (TEXT OF REVERSE SIDE OF BOND)

     This Bond is one of an authorized series of Bonds of the Issuer in the
aggregate principal amount of $115,000,000, designated as Peninsula Ports
Authority of Virginia Port Facility Refunding Revenue Bonds (Zeigler Coal
Project) Series 1997 (the "Bonds") authorized by duly adopted resolutions of
the Issuer, and issued under and secured by the Indenture in full conformity
with the Constitution and laws of the Commonwealth of Virginia.  The Bonds are
issued for the purpose of providing funds for refinancing the costs of
acquisition, construction and improvement of certain port facilities (the
"Project") for the  transshipment of coal located at Pier 9, Harbor Access
Road, Newport News, Virginia (the "Plant") of Zeigler Coal Holding Company (the
"Company").  Pursuant to the Financing Agreement (the "Agreement") dated as of
August 1, 1997 between the Issuer and the Company, the Company has agreed to
make Debt Service Payments, to the Trustee, on behalf of the Issuer, in amounts
and at the times sufficient to pay the principal of, premium, if any, and
interest on the Bonds.  The Company has also agreed to pay the Purchase Price
of all Bonds tendered or deemed tendered for purchase pursuant to the terms of
the Indenture.

     The Company has caused to be issued and delivered to the Trustee by Bank
of America National Trust and Savings Association, an irrevocable letter of
credit pursuant to which the Trustee is authorized, subject to the terms and
conditions thereof, to draw up to (a) an amount equal to the principal amount
of the Bonds (i) to enable the Trustee to pay the principal amount of the Bonds
when due at maturity or upon redemption or acceleration and (ii) to enable the
Trustee to pay the portion of the purchase price of Bonds tendered to it and
not remarketed corresponding to the principal amount of such Bonds, plus (b) an
amount equal to 45 days accrued interest on the outstanding Bonds at a maximum
rate of 10%,  (i) to enable the Trustee to pay interest on the Bonds when due
and (ii) to enable the Trustee to pay the portion of the purchase price of
Bonds tendered to it and not remarketed corresponding to the accrued interest
on such Bonds.  Such irrevocable letter of credit or any alternate letter of
credit delivered to the Trustee in accordance with the terms of the Indenture
is herein called the "Letter of Credit".  As used herein, the term "Bank" shall
mean Bank of America National Trust and Savings Association as issuer of the
Letter of Credit or the bank issuing any Alternate Letter of Credit.  The
Letter of Credit expires on October 19, 1997, unless terminated earlier
pursuant to its terms or extended.  Subject to the provisions of the Indenture,
the Company may, but is not required to, cause the Letter of Credit to be
extended or replaced with an Alternate Letter of Credit having substantially the
same terms.  The Bank is under no obligation to extend the Letter of Credit. 
Unless the Letter of Credit is extended or 
        


                                     A-5

replaced in accordance with the terms of the Indenture, this Bond will become
subject to mandatory tender for purchase, as described below.  The Letter of
Credit is being issued pursuant to a Reimbursement Agreement (as the same may be
amended or replaced, the "Reimbursement Agreement") between the Bank and the
Company.  The Company is obligated, among other things, to reimburse the Bank
for all drawings under the Letter of Credit.
        
     Reference is made to:  (a) the Indenture, the Agreement and the Letter of
Credit for provisions concerning the rights of the registered owners and the
rights and obligations of the Issuer, the Company, the Bank and the Trustee;
and (b) the Remarketing Agreement pursuant to which Goldman, Sachs & Co. is
serving as remarketing agent for the purposes set forth in the Indenture (such
agent or its successors being herein referred to as the "Remarketing Agent").
The acceptance of the terms and conditions of the foregoing documents
(including amplifications and qualifications of the provisions hereof), each of
which is on file at the principal corporate trust office of the Trustee, is an
explicit and material part of the consideration of the Issuer's issuance
hereof, and each registered owner hereof by acceptance of this Bond accepts and
assents to all such terms and conditions as if fully set forth herein.

     Capitalized terms used in this Bond which are not defined herein but which
are defined in the Indenture shall have the respective meanings set forth in
the Indenture.

                               INTEREST ON BONDS

     The Bonds shall initially accrue interest at the Daily Rate herein
described, and will be subject to conversion as herein provided.  The rate of
interest applicable to any Rate Period shall be determined in accordance with
the applicable provisions of the Indenture.  All computations of interest shall
be based on 365- or 366-day years for the actual number of days elapsed; except
for interest at Term Rates, which shall be computed on the basis of 360-day
years of twelve 30-day months, and interest at Flexible and Weekly Rates, which
shall be computed on the basis of a 365- or 366-day year, as appropriate, for
the actual number of days elapsed, based on the year in which such rate period
commences.  Notwithstanding any provision of this Bond or the Indenture to the
contrary, in no event shall the cumulative amount of interest paid or payable
on this Bond (including interest calculated as provided herein, together with
all other amounts that constitute interest on this Bond under the laws of the
State which are contracted for, charged, reserved, taken or received pursuant
to the Bond Documents) through any date of payment of interest or through the
date of payment of this Bond (whether at maturity, by acceleration or upon
earlier redemption) exceed the "net interest cost" which will produce a "net
effective interest rate" equal to the maximum rate permitted by Virginia law.

     "Rate Period" shall mean, when used with respect to any particular rate of
interest determined as hereinafter provided, the period from and including the
effective date of such rate to (but not including) the effective date of the
rate of interest next determined as hereinafter provided.

     The Bonds may accrue interest at Interest Rates effective for periods
(each an "Interest Rate Period") selected by the Company, or, under the
circumstances set out in the Indenture, by the Remarketing Agent from time to
time.  The Interest Rates for the Bonds, which will be determined by the
Remarketing Agent, are as follows:



                                     A-6
<PAGE>   74

Flexible Rate.

     While the Bonds accrue interest at Flexible Rates, the interest rate for
each particular Bond will be determined by the Remarketing Agent and will
remain in effect from and including the commencement date of the Flexible Rate
Period selected for that Bond by the Remarketing Agent to, but not including,
the last date thereof.  While the Bonds are in the Flexible Rate mode, Bonds
may have successive Flexible Rate Periods of any duration up to 270 days each
(or such lower maximum number as is then permitted under the Indenture) and any
Bond may accrue interest at a rate and for a period different from any other
Bond.

Daily Rate.

     While the Bonds accrue interest at a Daily Rate, the interest rate
established for the Bonds will be effective from day to day until changed by
the Remarketing Agent.

Weekly Rate.

     While the Bonds accrue interest at a Weekly Rate, the rate of interest on
the Bonds will be determined weekly by the Remarketing Agent to be effective
for a seven day period commencing on Wednesday of the week of such
determination.  (The length of the period, the day of commencement and the last
day of the period may vary in the event of a conversion to or from a Weekly
Rate.)

Term Rate.

     While the Bonds accrue interest at a Term Rate, the interest rate will be
determined by the Remarketing Agent to remain in effect for a term of one year
or any whole multiple of one year selected by the Company.

     The interest rate mode established will remain in effect until changed by
the Issuer and the Company, in accordance with the Indenture.  During each
Interest Rate Period, the rate of interest on the Bonds shall be that rate
which, in the judgment of the Remarketing Agent, would cause the Bonds to have
a market value as of the date of determination equal to the principal amount
thereof, taking into account prevailing market conditions, and with respect to
Flexible Rates, the Remarketing Agent shall determine the Flexible Rate and the
Flexible Rate Period for each Bond at such rate and for such period as it deems
advisable in order to minimize the net interest cost on the Bonds, taking into
account prevailing market conditions.

     Bonds which accrue interest at Flexible Rates will be issued in the
denominations of $100,000 and any integral multiples of $1,000 in excess
thereof.  Bonds which accrue interest at a Daily or  Weekly Rate will be issued
in denominations of $100,000 and whole multiples thereof.  Bonds which accrue
interest at a Term Rate will be issued in the denomination of $5,000 and whole
multiples thereof.


                                OPTIONAL TENDERS

     While this Bond accrues interest at a Daily, Weekly or Term Rate, the
registered owner of this Bond has the right to tender this Bond for purchase at
the principal amount hereof plus accrued interest as follows:  (i) during a
Daily Rate Period on any Business Day upon personal, electronic or telephone
notice to the Trustee prior to 11:00 a.m., New York City time, on such Business
Day, (ii) during a Weekly Rate Period on any



                                     A-7
<PAGE>   75

Business Day upon written or electronic notice to the Trustee on or prior to
5:00 p.m., New York City time, on any Business Day at least seven days prior to
the Business Day on which this Bond is tendered for purchase or (iii) during a
Term Rate Period on the first day of the next succeeding Rate Period upon
written or electronic notice to the Trustee on or prior to 5:00 p.m., New York
City time, on any Business Day at least seven days prior to such day.


                               MANDATORY TENDERS

     While this Bond accrues interest at a Flexible Rate, this Bond is subject
to mandatory tender on the day after the last day of each Flexible Rate Period
applicable to this Bond.  While this Bond accrues interest at Daily, Weekly or
Term Rates, this Bond is subject to mandatory tender on the effective date of a
change from one interest rate mode to a different interest rate mode (except
for changes between a Daily Rate and Weekly Rate) or of a change from a Term
Rate Period to a Term Rate Period of different duration.  This Bond is subject
to mandatory tender on the Interest Payment Date next preceding the Expiration
Date of the Letter of Credit unless the Trustee has received notice that the
Letter of Credit has been or will be extended or replaced with an Alternate
Letter of Credit as provided in the Indenture.

     Interest on any Bond which is not tendered on the mandatory tender date,
but for which there has been irrevocably deposited with the Trustee an amount
sufficient to pay the purchase price thereof, shall cease to accrue interest on
the mandatory tender date, and the registered owner of such Bond shall not be
entitled to any payment other than the purchase price for such Bond, and such
Bond shall no longer be outstanding and entitled to the benefits of the
Indenture, except for the payment of the purchase price of such Bond from
monies held by the Trustee for such payment.  On the mandatory tender date the
Trustee shall authenticate and deliver substitute Bonds in lieu of such
untendered Bonds.


                       WRITTEN NOTICE OF RATE MODE CHANGE

     The Trustee shall give notice, by first class mail, to the registered
owners of all Bonds of the proposed conversion from one interest rate mode to
another interest rate mode at least 15 days before the proposed conversion date
while the Bonds accrue interest at Flexible, Daily or Weekly Rates at least 30
days before the proposed conversion date while the Bonds accrue interest at a
Term Rate.


                             INTEREST PAYMENT DATES

     While this Bond accrues interest at a Flexible Rate, interest is payable
on the day after the last day of each Flexible Rate Period.  While this Bond
accrues interest at Daily or Weekly Rates, interest is payable on the first
Business Day of each month.  During any Term Rate Period, interest is payable
semiannually on the first day of the sixth month after the commencement of such
Term Rate Period and the first day of each sixth month thereafter provided that
the last Interest Payment Date for any Term Rate Period which is followed by a
Flexible, Daily or Weekly Rate Period shall be the first Business Day of the
sixth month following the preceding Interest Payment Date.

proceeds of the sale of the Bonds and any amounts received by it under this
Agreement, including payments received from the Company or pursuant to the
Letter of Credit.  No provision in this Agreement or any obligation herein

                                  ARTICLE IV

                            NATURE OF OBLIGATIONS

     Section 4.1. Loan of Proceeds to Company.  The Issuer agrees, upon the

received by the Issuer from the sale of the Bonds available to the Company as a
loan.  The loan shall be disbursed by the Issuer by deposit of the proceeds of
the Bonds with the Trustee for deposit in accordance with the Escrow Agreement
described in Section 6.01 of the Indenture.

     Section 4.2. Amounts Payable.

     (a) As and for repayment of the loan to the Company by the Issuer pursuant
to Section 4.1 hereof, the Company shall pay to the Trustee for the account of
the Issuer as a Debt Service Payment an amount equal to the aggregate principal
amount of the Bonds from time to time Outstanding and, as interest on its
obligation to pay such amount, an amount equal to interest on the Bonds and, in
the event of any redemption of the Bonds prior to the maturity thereof, the
premium, if any, due in respect thereof.  The Debt Service Payments shall be
paid in installments due no later than 10:00 a.m. on the dates, in immediately
available funds in the amounts, and in the manner provided in the Indenture to
enable the Trustee, on behalf of the Issuer, to cause amounts to be deposited
in the Debt Service Fund to equal the amount required for the timely payment of
the principal of and premium, if any, and interest on the Bonds as the same
shall become due and payable, whether at maturity, upon redemption, by
acceleration, or otherwise; provided, however, that the obligation of the
Company to make any such payment hereunder shall be reduced by the amount of
any available moneys held by the Trustee in the Debt Service Fund for such
purpose.

     (b) The Company shall also pay to or on behalf of the Issuer the fees and
reasonable expenses of the Issuer (including reasonable fees and expenses of
counsel) which have been disclosed to it on the Issue Date related to the
issuance and sale of the Bonds and such other costs, reimbursements, fees and
expenses for which it may be liable under Section 10.8 hereof in connection
with the Issuer's performance of its duties and obligations under this
Agreement, the Indenture and the other Bond Documents, within 30 days after
receipt of a written request from the Issuer for such payment.


                                      6

<PAGE>   11



     (c) The Company shall also pay the reasonable fees and expenses (including
reasonable fees and expenses of counsel) of the Trustee under the Indenture and
other Financing Documents (including this Agreement), such reasonable fees and
expenses to be paid directly to the Trustee for its account as and when such
reasonable fees and expenses become due and payable, and any reasonable expense
in connection with any redemption of the Bonds; provided, however, that so long
as no Event of Default exists hereunder, the Company shall not be responsible
for payment of any fees or expenses, including fees and expenses of counsel
(except for the Trustee's annual fee), unless the Company has been specifically
informed of the nature and amount of such fees and expenses and has given
written authorization therefor; provided, however, that no such authorization
shall be required if the Trustee determines, owing to extraordinary
circumstances, that such prior authorization is inconsistent with the
performance of its fiduciary duties hereunder.  The Company may, without
creating a default hereunder or under the Indenture, contest in good faith the
necessity for and the reasonableness of any such services and expenses before
making payment therefor.

     (d) In addition to all other costs and expenses due hereunder, the Company
shall pay all reasonable costs and expenses of enforcement of the terms and
provisions hereof and of the Indenture including, without limitation, those
referred to in Section 7.5 hereof and Sections 11.02, 11.03, and 12.11 of the
Indenture.

     (e) The Company shall also compute the amount of arbitrage rebate at the
times and in the manner required by the Tax Agreement and shall pay amounts
equal to any rebatable arbitrage to the United States at the times and in the
amounts required by the Tax Agreement.

     Section 4.3. Purchase Price Payments.  The Company hereby agrees to pay the
amounts required under Section 4.03(b)(ii) of the Indenture at the times stated
therein to provide for the payment of the Purchase Price of the Bonds to the
extent that funds are not available from the proceeds of any remarketing or
from a drawing under the Letter of Credit.

     Section 4.4. Obligations of Company Hereunder Unconditional.  The
obligations of the Company to make the payments required in Sections 4.2, 4.3
and the other sections hereof and to perform and observe the other agreements
contained in Sections 2.2, 5.4 and 5.6, hereof, and in Article IX hereof, shall
be absolute and unconditional and shall not be subject to any defense or any
right of setoff, counterclaim, or recoupment arising out of any breach by the
Issuer or the Trustee of any obligation to the Company, whether hereunder or
otherwise, or out of any indebtedness or liability at any time owing to the
Company by the Issuer or the Trustee.  Until such time as the principal of,
premium, if any, and interest on the Bonds shall have been fully paid or
provision for the payment thereof shall have been made in accordance with the
Indenture, the Company (i) will not suspend or discontinue any payments
provided for in Section 4.2(a) hereof, (ii) will perform and observe all other
agreements contained in this Agreement, and (iii) will not terminate the Term
of Agreement for any cause including, without limiting the generality of the
foregoing, the occurrence of any acts or circumstances that may constitute
failure of consideration, eviction, or constructive eviction, destruction of or
damage to all or a portion of the Plant, the taking by eminent domain of title
to or temporary use of any or all of the Plant, commercial frustration of
purpose, any change in the tax or other laws of or any action by the United
States of America or of the State or any political subdivision of either
thereof or any failure of the Issuer or the Trustee to perform and observe any
agreement, whether express or implied, or any duty, liability, or obligation
arising out of or connected with this Agreement, except to the extent permitted
by this Agreement.

              (iii) For each Covered Employee in Category C and D, the

                                   Section 5

                Severance Benefits Payable to Covered Employees


        5.1   In the event a Change of Control occurs on or prior to 
December 31, 1998, a Covered Employee who is employed by the Company on the
date of the Change of Control shall be entitled to the severance benefits as

Employment within the twelve month period following the Change of Control.
Notwithstanding the foregoing, the Covered Employee shall not be entitled to

        5.2   A Covered Employee who has become entitled to severance benefits
pursuant to Section 5.1 shall receive the following benefits:

        (a)   Such Covered Employee Shall receive a cash payment in an amount
   determined as follows depending on the Category to which the Covered
   Employee is


                                     - 6 -


<PAGE>   7

      assigned on the effective date of the Change of Control, less the amount,
      if any, of the Retention Bonus paid to such Covered Employee pursuant
      hereto:

                 (i)   For each Covered Employee in Category A, the
                       severance payment shall equal two times the sum of (1)
                       his or her Base Salary plus (2) his or her highest
                       target bonus in effect for such calendar year (whether
                       or not such target bonus was earned or likely to be
                       earned).  For example, a Covered Employee with a
                       $200,000 Base Salary and a $120,000 target bonus would
                       be entitled to receive a severance payment of $640,000.

                 (ii)  For each Covered Employee in Category B, the severance
                       payment shall equal the sum of (1) his or her Base
                       Salary plus (2) his or her highest target bonus in
                       effect for such calendar year (whether or not such
                       target bonus was earned or likely to be earned). For
                       example, a Covered Employee with a $150,000 Base Salary
                       and a $50,000 target bonus would be entitled to receive
                       a severance payment of $200,000.

                 (iii) For each Covered Employee in Category C, the severance
                       payment shall equal an amount determined by multiplying
                       his or her Weekly Base Salary by the factor of three
                       (3) multiplied by  his or her Years of Service; 
                       provided that, in no event shall such payment be more
                       than his or her Base Salary or less than his or her
                       Weekly Base Salary multiplied by twelve (12).
 
                 (iv)  For each Covered Employee in Category D, the severance
                       payment shall equal an amount determined by multiplying
                       his or her Weekly Base Salary by the factor of three
                       (3) multiplied by his of her Years of Service; provided
                       that, in no event shall such payment be more than his
                       or her Base Salary and, provided further, a Category
                       D Covered Employee shall not be entitled to any
                       severance payment unless he or she has been employed by
                       the Company for at least six months as of the effective
                       date of the Change in Control.

           (b)   Such Covered Employee shall continue to be covered under the
      Company's health and dental insurance plan and life insurance plan as in
      effect immediately prior to his or her Termination of Employment for a
      period of twelve months immediately following his or her Termination of
      Employment.  Such coverage shall be provided on the same terms and
      conditions applicable to active employees (as the same may be amended
      from time to time and subject to any legal limitations) in effect for
      such


                                     - 7 -

      Covered Employee on the day before the Termination of Employment;
      provided, however, that such coverage shall be counted toward the period
      of continuation of coverage under the group health plan continuation
      coverage provision of ERISA and the Code; provided further, that such
      coverage shall end immediately upon the Covered Employee becoming
      eligible for coverage under any employer health plan as a result of
      subsequent employment.

            6.1 This Plan shall become effective on December 1, 1997 and shall

                                   Section 7

                              General Provisions


     7.1    No employee whose employment is terminated prior to a Change of
Control and no Covered Employee whose employment is terminated more than twelve
months after a Change of Control shall be entitled to any severance benefits
under this Plan.  No provision of this Plan shall be interpreted or construed:

            (i)   to entitle any Covered Employee or other person to
                  employment by the Company or to any notice of 
                  termination of employment by the Company,

            (ii)  to limit or restrict in any manner the right
                  of the Company to terminate any Covered
                  Employee's or other person's employment, or

            (iii) to change in any manner the conditions, terms,
                  responsibilities or duties of employment of any Covered
                  Employee or other person; provided that each Covered Employee
                  who is subject to a Terminantion of Employment within the
                  twelve-month period following a Change of Control shall be
                  entitled to receive the severance benefits as provided in
                  this  Plan.
        
     7.2    This Plan shall not limit in any respect the right of the Company to
enter into any contract or other arrangement for the making of severance or
other payments to any employee, whether or not relating to a Change of Control,
or for the making of any other payment in the event of a Change of Control.
The amount of severance payment which a Covered Employee is entitled to receive
hereunder shall be reduced by the amount of any other severance payments made
to such person under any contract or otherwise, which are made no later than 30
days following the Termination of Employment of such employee.

     7.3    All matters regarding this Plan and its application (including the
construction or interpretation of any provision hereof) shall be determined by
the Board of Directors or, following a Change of Control, by a majority of the
individuals (excluding any who are unable to act) who were directors of Zeigler
immediately preceding such Change of Control (whether or not any such
individuals remain a director at the time of such determination).  Any
such determination shall be binding upon and enforceable by Zeigler, all
Covered Employees and all other persons.

        7.4  This Plan shall be binding upon Zeigler and each Covered Employee
and their respective successors, assigns, heirs and representatives.  Zeigler
shall cause any person which acquires in any manner (including by merger)
substantially all of Zeigler's assets or which merges with Zeigler to assume
all provisions of this Plan with respect to all Covered Employees employed in
connection with the assets being acquired.  Such assumption shall be by written
instrument in form and substance satisfactory to a majority of the directors of
Zeigler in office immediately prior to such acquisition of assets.  Such
assumption shall not relieve Zeigler of its obligations under this Plan.
        
        7.5  The validity, interpretation, construction and performance of this
Plan shall be governed by the laws of the State of Illinois.

        7.6  For the purpose of this Plan, notices and all other communications
provided for in this Plan shall be in writing and shall be deemed to have been
duly given when delivered or mailed by certified or registered mail, return
receipt requested, postage prepaid, addressed:

        (a)  if to an Employee, to his latest address as reflected on the
