    This Annual Report on Form 10-K includes certain forward-looking information
(within the meaning of the Private Securities Litigation Reform Act of 1995)
that involves risks and uncertainty, including certain assumptions regarding the
future performance of USEC. Actual results and trends may differ materially
depending upon a variety of factors, including, without limitation, market
demand for USEC's services, pricing trends in the uranium and enrichment
markets, deliveries and costs under the Russian Contract, the availability and
cost of electric power, USEC's ability to successfully execute its internal
performance plans, the refueling cycles of USEC's customers, and the impact of
any government regulation. Further, customer commitments under their contracts
are based on customers' estimates of their future requirements.

PART I

ITEM 1.  BUSINESS

OVERVIEW

    USEC Inc. ("USEC"), a global energy company, is the world leader in the sale
of uranium fuel enrichment services for commercial nuclear power plants. Uranium
enrichment is a critical step in transforming uranium into fuel for nuclear
reactors to produce electricity. USEC, including its wholly owned subsidiaries,
was organized under Delaware law in connection with the privatization of the
United States Enrichment Corporation, a corporation then wholly owned by the
U.S. Government. In accordance with the 1996 USEC Privatization Act
("Privatization Act"), the assets and obligations were transferred to USEC, and
USEC completed an initial public offering ("IPO") of common stock on July 28,
1998 (the "IPO Date"), thereby transferring all of the U.S. Government's
interest in the business, with the exception of certain liabilities from prior
operations of the U.S. Government. References to USEC include USEC's wholly
owned subsidiaries as well as the predecessor to USEC unless the context
requires otherwise.

SERVICES AND PRODUCTS

    USEC supplies uranium enrichment services and uranium to approximately 60
electric utilities for use in about 170 nuclear reactors. Substantially all of
USEC's revenue is derived from the sale of uranium enrichment services with
customers supplying uranium to be enriched. USEC also derives revenue from sales
of natural uranium and enriched uranium product ("EUP"). USEC has a significant
inventory of natural uranium which it may sell to customers as uranium or in the
form of EUP.

    Generally, contracts with customers to provide separative work units (SWU)
are long-term requirements contracts under which the customer is obligated to
purchase a specified percentage of its enrichment services from USEC.
Consequently, annual sales are dependent upon the customers' requirements for
enrichment services, which are driven by nuclear reactor refueling schedules,
reactor maintenance schedules, customers' considerations of costs, and
regulatory actions. Under delivery optimization and other customer oriented
programs, USEC advance ships enriched uranium to nuclear fuel fabricators for
scheduled or anticipated orders from utility customers.

    Revenue from domestic customers represented 62% and revenue from foreign
customers represented 38% of total revenue in fiscal 1999. No one customer
accounted for more than 10% of revenue in fiscal years 1997, 1998 or 1999.
Information with respect to revenue attributable to domestic and foreign
customers is included in the Consolidated Financial Statements.

    As found in nature, uranium consists of three isotopes, the two principal
ones being uranium-235 ("U(235)") and uranium-238 ("U(238)"). U(238) is the more
abundant isotope, but is not fissionable. U(235) is the fissionable isotope, but
its concentration in natural uranium is only about .711% by weight. Light water
nuclear reactors, which are operated by most nuclear utilities in the world
today, require low-enriched uranium fuel with a U(235) concentration in the
range of 3% to 5% by weight. Uranium enrichment is the process by which the
concentration of U(235) is increased to that level. The standard measure of
effort or service in the uranium enrichment industry is separative work units or
SWU. A SWU is the amount of effort that is required to transform a given amount
of natural uranium into two streams of uranium, one enriched in the U(235)
isotope and the other depleted in the U(235) isotope.

BACKLOG

    Under USEC's contracts, customers are required to provide non-binding
estimates of their SWU requirements to facilitate USEC's ability to plan for
production requirements. Backlog is the aggregate dollar amount of enrichment
services that USEC expects to sell pursuant to its long-term requirements
contracts with utilities. Based on customers' estimates of their requirements as
of June 30, 1999, USEC had long-term requirements contracts with utilities to
provide uranium enrichment services aggregating $6.5 billion through fiscal 2010
(including $3.3 billion through fiscal 2002) compared with $6.9 billion at June
30, 1998.

VARIABILITY OF REVENUE AND OPERATING RESULTS

    Revenue and operating results can fluctuate significantly from quarter to
quarter, and in some cases, year to year. Customer requirements are determined
by refueling schedules for nuclear reactors, which generally range from 12 to 18
months (or in some cases up to 24 months). These schedules are in turn affected
by, among other things, the seasonal nature of electricity demand, reactor
maintenance, and reactors beginning or terminating operations. Utilities
typically schedule the shutdown of their reactors for refueling to coincide with
the low electricity demand periods of spring and fall. Thus, some reactors are
scheduled for fall refueling, spring refueling or for 18-month cycles
alternating between both seasons. USEC provides customers from 10 to 30 days to
take delivery of ordered product. Refueling orders typically average $14.0
million per customer order.

    Sales of uranium supplement revenue from sales of SWU. However, given the
volatility in the uranium market, USEC may not be able to sell its inventory of
uranium at anticipated prices and quantities. A decline in the market price of
uranium below USEC's carrying cost could have an adverse effect on results of
operations.

PLANT OPERATIONS - ELECTRIC POWER AND MATERIALS AND SUPPLIES

    USEC enriches uranium at two gaseous diffusion plants (the "plants") located
in Paducah, Kentucky and near Portsmouth, Ohio. The gaseous diffusion process
involves the passage of uranium in a gaseous form through a series of porous
barriers. Uranium is continuously enriched in U(235) as it moves through the
process. Because U(235) is lighter, it passes through the barrier more readily
than does U(238), resulting in gaseous uranium that is enriched in U(235), the
fissionable isotope.

    The plants require substantial amounts of electric power to enrich uranium.
USEC acquires most of its electric power from two corporations, Ohio Valley
Electric Corporation ("OVEC"), the main supplier to the Portsmouth plant, and
Electric Energy, Inc. ("EEI"), the main supplier to the Paducah plant. The U.S.
Department of Energy ("DOE") transferred to USEC the benefits of power purchase
arrangements with OVEC and EEI (the "Electricity MOA"). USEC also has an
agreement with the Tennessee Valley Authority for the purchase of non-firm power
for the Paducah plant. Firm and non-firm power represented 70% and 30%,
respectively, of power purchased in fiscal 1999. During certain periods,
including the summer months when power costs are typically higher, almost all of
the power supplied to the Paducah plant must be purchased at market-based rates
because it is non-firm power. Depending on inventory levels and planned
shipments, USEC reduces production at the Paducah plant when the cost of
non-firm power is high.

    Equipment components (such as compressors, coolers, motors and valves)
requiring maintenance are removed from the process and repaired or rebuilt on
site at each of the plants. Common


                                       4
<PAGE>   5


industrial components, such as the breakers, condensers and transformers in the
electrical system, are procured as needed. Since the plants were constructed in
the 1950s, some components and systems may no longer be produced, and spare
parts may not be readily available. In these situations, replacement components
or systems are identified, tested, and procured from existing commercial
sources, or the plants' technical and fabrication capabilities are utilized to
design and build replacements. Another source of replacement equipment has been
DOE's Oak Ridge, Tennessee, enrichment facility, which has been shut down.

    The plants use freon as the primary process coolant. The production of freon
in the United States was terminated December 31, 1995. Freon leaks from pipe
joints, sight glasses, valves, coolers and condensers. Leakage from the plants
is at about a 6% rate, resulting in leakage of 750,000 pounds of freon per year,
a level that is within the limits set by the Environmental Protection Agency.
USEC believes that its efforts to reduce freon losses and its strategic
inventory of 2.0 million pounds of freon should be adequate to allow the plants
to continue to utilize freon through at least calendar year 2001. A program is
underway to validate an alternative coolant to be used once the freon inventory
is depleted.

    Reductions in production equipment availability result from equipment
failures and planned maintenance. In addition, USEC may elect to reduce
equipment utilization if electric power is in short supply or prohibitively
expensive. Paducah equipment utilization was 76% of planned capacity in fiscal
1999 due to the curtailment of production during the summer and early fall of
1998 to reduce the impact of high costs for electric power. Portsmouth equipment
utilization was 74% of planned capacity due to equipment failures and increased
maintenance requirements.

RUSSIAN CONTRACT

    USEC has been designated by the U.S. Government to act as its Executive
Agent in connection with a government-to-government agreement between the United
States and the Russian Federation under which USEC purchases SWU derived from
dismantled Soviet nuclear weapons. In January 1994, USEC on behalf of the U.S.
Government signed an agreement (the "Russian Contract") with AO Techsnabexport
("Tenex"), Executive Agent for the Russian Federation. Under the contract, USEC
expects to purchase up to approximately 92 million SWU over a 20-year period.

    USEC has ordered 5.7 million SWU for delivery under the Russian Contract in
calendar year 1999, of which 1.8 million SWU had been purchased as of June 30,
1999. SWU quantities and prices, subject to adjustment for U.S. inflation, have
been established through calendar year 2001. Global market prices for SWU have
declined below the price being paid for SWU under the Russian Contract. USEC has
begun negotiations to align the Russian Contract with market pricing realities.

    In April 1997, USEC entered into a memorandum of agreement (the "Executive
Agent MOA") with the United States Department of State and the DOE whereby USEC
agreed to continue to serve as the U.S. Executive Agent following the
privatization. Under the terms of the government-to-government agreement and the
Executive Agent MOA, USEC can be terminated, or resign, as U.S. Executive Agent
upon the provision of 30 days' notice. In the event of termination or
resignation, USEC would have the right and the obligation to purchase SWU that
is to be delivered during the calendar year of the date of termination and the
following calendar year. The Executive Agent MOA also provides that the U.S.
Government can appoint alternate or additional executive agents to carry out the
government-to-government agreement.

ALTERNATIVE URANIUM ENRICHMENT TECHNOLOGIES

    AVLIS

    In June 1999, USEC suspended further development of an advanced uranium
enrichment technology known as Atomic Vapor Laser Isotope Separation ("AVLIS").
In connection with a comprehensive review of operating and economic factors,
USEC reexamined the AVLIS technology, performance, prospects, risks and growing
financial requirements as well as the economic impact of competitive marketplace
dynamics and concluded that the returns were not sufficient to outweigh the
risks and ongoing capital expenditures necessary to develop and construct an
AVLIS plant.

    USEC terminated AVLIS efforts with its contractors, implemented workforce
reductions and is conducting an orderly ramp-down of AVLIS activities at
Lawrence Livermore National Laboratory in California. The suspension of AVLIS
resulted in a special charge of $34.7 million ($22.7 million or $.23 per share
after tax) in fiscal 1999 for contract terminations, shutdown activities costs
and employee severance and benefit arrangements. As all project development
costs have been expensed, there was no asset write-off. Project development
costs for AVLIS amounted to $133.7 million, $134.7 million and $103.9 million in
fiscal years 1997, 1998 and 1999, respectively.

    Centrifuge

    During fiscal 2000, USEC plans to evaluate the availability and economics of
centrifuge technology, an alternative enrichment technology currently used by
some foreign competitors.

    SILEX

    In fiscal 1997, USEC entered into an exclusive agreement to explore an
advanced laser-based enrichment technology called SILEX. USEC acquired the
rights to the commercial utilization of the SILEX process. USEC is currently
evaluating whether the SILEX technology has the potential to be deployed as an
economic source of enrichment production in the early 21st century. The SILEX
technology is in the early stage of research and development. USEC's spending on
SILEX development activities amounted to $7.8 million, $2.0 million, and $2.5
million in fiscal years 1997, 1998 and 1999, respectively.

COMPETITION

    The highly competitive global uranium enrichment industry has four major
producers:
     o    USEC;
     o    Urenco, a consortium of British and Dutch governments and private
          German utilities;
     o    Eurodif, a multinational consortium controlled by the French
          government; and
     o    Tenex, a Russian government entity.

    USEC has experienced intense price competition from Urenco and Eurodif, both
of which have been aggressive in their attempts to increase market share in the
United States.

    There are also smaller suppliers in China and Japan that primarily serve
only a portion of their respective domestic markets. While there are only a few
primary suppliers, there is an excess of production capacity as well as an
additional supply of enriched uranium that is available for commercial use from
the dismantlement of nuclear weapons in the former Soviet Union and the



                                       6
<PAGE>   7


United States. Much of this excess capacity is held by Tenex, that is subject to
certain trade restrictions on sales in the U.S. and other markets. USEC also
holds significant excess capacity. All of USEC's competitors are owned or
controlled by foreign governments which may make business decisions influenced
by political and economic policy considerations rather than solely on prevailing
market conditions. USEC believes that a significant portion of the world market
may be closed to USEC because purchasers in certain areas may favor their local
producers, due to government influence or other political considerations. In
addition, there have been recent decisions by certain European utilities to
liquidate strategic SWU inventories.

    Urenco, Tenex, and Japan Nuclear Fuels Limited ("JNFL") use centrifuge
technology that requires a higher initial capital investment but has lower
operating costs than current gaseous diffusion technology. USEC believes that
Urenco and JNFL have expansion plans which, if implemented, could increase world
capacity by 3.6 million SWU by 2006. Eurodif and JNFL have announced that they
are exploring new enrichment technologies.

    Global enrichment suppliers compete primarily in terms of price, and
secondarily on reliability of supply and customer service. USEC is committed to
being competitive on price and delivering superior customer service. USEC
believes that customers are attracted to its reputation as a reliable long-term
supplier of enriched uranium and intends to continue strengthening this
reputation.

NUCLEAR REGULATORY COMMISSION - REGULATION

    The plants are certified and regulated extensively by the Nuclear Regulatory
Commission ("NRC"). The NRC issued Certificates of Compliance to USEC for the
operation of the plants in November 1996 and began regulatory oversight in March
1997. The term of the NRC certification of the plants has been renewed for a
five-year period ending December 2003. The NRC found the plants to be generally
in compliance with its regulations. However, exceptions were noted in certain
compliance plans which set forth binding commitments for actions and schedules
to achieve full compliance (the "Compliance Plan"). Over 94% of the Compliance
Plan actions were completed as of June 30, 1999.

    The Compliance Plan requires the Paducah plant to complete seismic upgrading
of the two main process buildings to reduce the risk of release of radioactive
and hazardous material in the event of an earthquake. The Paducah plant is
located near the New Madrid fault line. Capital expenditures for seismic
improvements amounted to $21.0 million in fiscal 1999, and additional capital
expenditures of $20.5 million are expected in fiscal 2000 to complete the
upgrades. Until the modifications are completed, USEC continues to maintain
strict limits on operations in those buildings to minimize the amount of
material that could be released in the unlikely event of an earthquake.

    The Compliance Plan required USEC to update a DOE analysis to determine the
appropriate earthquake level for the evaluation of equipment and structures at
the Paducah plant. USEC has submitted this updated analysis and it is currently
being reviewed by the NRC. Depending on the results of this review and the
application of NRC's backfit requirements, additional seismic upgrades to the
process buildings and other site structures and components may need to be
implemented.

    The NRC has the authority to issue Notices of Violation for violations of
the Atomic Energy Act of 1954, NRC regulations, conditions of a certificate,
Compliance Plan, or Order. The NRC has the authority to impose civil penalties
for certain violations of its regulations. In fiscal 1999, USEC received Notices
of Violations for certain violations of these regulations and certificate
conditions,



                                       7
<PAGE>   8



none of which exceeded $100,000. USEC does not expect that any proposed notices
it has received will have a material adverse effect on its financial position or
results of operations. In each case, USEC took corrective action to bring the
facilities into compliance with NRC regulations and identified long-term
improvements as well.

ENVIRONMENTAL MATTERS

    USEC's operations are subject to various federal, state and local
requirements regulating the discharge of materials into the environment or
otherwise relating to the protection of the environment. USEC's operations
generate low-level radioactive waste that is stored on-site or is shipped
off-site for disposal at a commercial facility. In addition, USEC's operations
generate hazardous waste and mixed waste (i.e., waste having both a radioactive
and hazardous component), most of which is shipped off-site for treatment and
disposal. Because of limited treatment and disposal capacity, some mixed waste
is being temporarily stored at DOE's permitted storage facilities at the plants.
USEC has entered into consent decrees with the States of Kentucky and Ohio which
permit the continued storage of mixed waste at DOE's permitted storage
facilities at the plants and provide for a schedule for sending the waste to
off-site treatment and disposal facilities, generally by the end of calendar
year 2000.

    USEC's operations generate depleted uranium that is currently being stored
at the plants. All liabilities arising out of the disposal of depleted uranium
generated before the IPO Date are direct liabilities of DOE. Additionally, the
Privatization Act requires DOE, upon USEC's request, to accept for disposal the
depleted uranium generated after the IPO Date in the event that depleted uranium
is determined to be a low-level radioactive waste, provided USEC reimburses DOE
for its costs. In June 1998, USEC paid DOE $50.0 million in consideration for
DOE assuming responsibility for a certain amount of depleted uranium generated
by USEC over the period October 1998 to September 2005.

    The plants were operated by agencies of the U.S. Government for
approximately 40 years prior to July 28, 1998. As a result of such operation of
the plants, there is contamination and other potential environmental
liabilities. The Paducah plant has been designated as a Superfund site, and both
plants are undergoing investigations under the Resource Conservation and
Recovery Act. Environmental liabilities associated with plant operations prior
to July 28, 1998, are the responsibility of the U.S. Government, except for
liabilities relating to the disposal of certain identified wastes generated by
USEC and stored at the plants. The Privatization Act and the Lease Agreement
(defined below) provide that DOE remains responsible for decontamination and
decommissioning of the plants.

    Reference is made to Management's Discussion and Analysis of Financial
Condition and Results of Operations and the Notes to Consolidated Financial
Statements included in this Annual Report on Form 10-K for information on
operating costs and capital expenditures relating to environmental matters.

OCCUPATIONAL SAFETY AND HEALTH

    USEC's operations are subject to regulations of the U.S. Occupational Safety
and Health Administration governing worker health and safety. USEC maintains a
comprehensive worker safety program that continually monitors key components of
the workplace environment, resulting in a solid worker safety record.

FOREIGN TRADE MATTERS

    USEC's exports to utilities located in countries comprising the European
Union take place within the framework of an agreement (the "EURATOM Agreement")
for cooperation between the United States and the European Atomic Energy
Community, which permits USEC to export low enriched uranium to the European
Union for as long as the EURATOM Agreement is in effect.

    USEC exports to utilities in other countries under similar agreements for
cooperation. If any such agreements lapse, terminate or are amended such that
USEC could not make sales or deliver enriched uranium to such jurisdictions, it
could have a material adverse effect on USEC's financial position and results of
operations.

    In 1991, U.S. producers of uranium and uranium workers filed a petition with
the U.S. Department of Commerce ("Commerce") alleging that uranium from
countries of the then-Soviet Union was being dumped (i.e. sold at unfair prices)
in the United States. A preliminary determination was issued that uranium
imported from Russia and several other former Soviet republics was being dumped
in the United States. Those and future imports were exposed to the risk of high
U.S. antidumping duties if Commerce issued an affirmative final dumping
determination and if the U.S. International Trade Commission ("ITC") also
determined that those imports were causing or threatening material injury to the
U.S. industry. The antidumping investigations of imports of uranium from Russia,
Kazakhstan, Kyrgyzstan, Tajikistan, Ukraine, and Uzbekistan were suspended as a
result of suspension agreements between Commerce and the respective governments
which limited imports of all forms of uranium, including enriched uranium.

    In January 1999, the antidumping duty investigation of uranium from
Kazakhstan was reinitiated as a result of the Government of Kazakhstan's
unilateral termination of the suspension agreement covering imports of uranium
from Kazakhstan. In June 1999, Commerce issued its final determination, which
concluded that imports of uranium from Kazakhstan were likely to be sold at less
than fair value in the United States. In July 1999, the ITC determined that
imports of uranium from Kazakhstan had not materially injured, nor did they
threaten to injure the domestic uranium industry. As a result, no restrictions
or duties are being imposed on uranium imports from Kazakhstan and the
antidumping duty investigation of uranium from Kazakhstan has been terminated.
USEC has appealed the ITC determination. In addition, USEC has filed a request
with Commerce that it clarify that the stockpile of enriched uranium product
located in Kazakhstan at the time of the dissolution of the Soviet Union is of
Russian origin and thus, falls under the Russian suspension agreement. This
stockpile is believed to be over 2.0 million SWU that may present a new source
of competition to USEC. If Commerce decides that this enriched uranium is not
subject to the Russian suspension agreement, it could be sold in the U.S.
market, which could depress market prices further, adversely impacting USEC's
profitability.

    The suspension agreements with Tajikistan and Ukraine have been terminated,
and imports of uranium from Ukraine are currently subject to antidumping duties.
The suspension agreements with Russia and Uzbekistan remain in force until March
31, 2004 and October 12, 2004, respectively, unless terminated earlier, such as
through the "sunset" review process described below or by a request for
termination by one of the governmental signatories. The suspension agreement
with Kyrgyzstan remains in force through October 15, 2002 unless terminated
earlier.

    The "sunset" review of the uranium suspension agreements with Kyrgyzstan,
Russia and Uzbekistan and the antidumping order of imports of uranium from
Ukraine commenced on August 2, 1999. Commerce initiated the "sunset" review
process which requires (1) Commerce to determine



                                       9
<PAGE>   10


whether termination of a suspension agreement or revocation of an antidumping
order is likely to lead to a continuation or recurrence of dumping, and (2) the
ITC to determine whether such termination or revocation is likely to lead to a
continuation or recurrence of material injury to the relevant U.S. industry. If
either Commerce or the ITC do not make the requisite determinations with respect
to a suspension agreement or antidumping order limiting imports of uranium from
a particular country, the agreement will be terminated or the order will be
revoked, and uranium from that country could be imported without trade
restrictions. If restrictions on imports of uranium are revoked as a result of
this "sunset" review process, USEC would face significantly increased
competition and market prices could be further depressed, adversely impacting
profitability.

CERTAIN ARRANGEMENTS INVOLVING THE U.S. GOVERNMENT

    Pursuant to an agreement with the United States Treasury Department, USEC
has committed to continue operation of the plants until at least January 2005,
subject to limited exceptions, including:
      o  events beyond the reasonable control of USEC, such as natural
         disasters;
      o  a decrease in annual worldwide demand to less than 28 million SWU;
      o  a decline in the average price for all SWU under USEC's long-term firm
         contracts to less than $80 per SWU (in 1998 dollars);
      o  a decline in the operating margin to below 10% in a consecutive
         twelve-month period;
      o  a decline in the interest coverage ratio to below 2.5x in a consecutive
         twelve-month period; or
      o  if the long-term corporate credit rating of USEC is, or is reasonably
         expected in the next twelve months to be, downgraded below an
         investment grade rating.

    None of the exceptions to USEC's obligation to operate the plants has
occurred. Based on information known, USEC does not anticipate that the average
SWU price under its long-term firm contracts is likely to fall below $80 per SWU
(in 1998 dollars) in the near future.

    In addition, USEC committed:
      o  to the extent commercially practicable, to take steps reasonably
         calculated in good faith to ensure that workforce reductions at the
         plants through fiscal 2000 are conducted in a manner consistent with
         USEC's strategic plan and do not exceed 500 employees; and
      o  to the extent commercially practicable, in each of fiscal years 1999
         and 2000, to seek to achieve such workforce reductions through a
         program of voluntary separation before instituting a program of
         involuntary separation.

    In connection with the privatization of USEC, the U.S. Government
established an enrichment oversight committee to monitor and coordinate the U.S.
interests relating to USEC's business in furtherance of:
      o  the full implementation of the government-to-government agreement
         relating to the disposition of Russian highly enriched uranium;
      o  the application of statutory, regulatory and contractual restrictions
         on foreign ownership, control or influence of USEC;
      o  the development and implementation of U.S. Government policy regarding
         uranium enrichment and related technologies, processes and data; and
      o  the collection and dissemination of information within the U.S.
         Government relevant to the foregoing objectives.


                                       10
<PAGE>   11


    In June 1998, USEC entered into a memorandum of agreement with DOE which
establishes annual and quarterly reporting requirements for USEC in support of
the oversight committee's purposes.

    USEC is a party to other arrangements with the U.S. Government, including
the Executive Agent MOA, the Lease Agreement (defined below) and the Electricity
MOA.

EMPLOYEES

    As of June 30, 1999, USEC had 3,960 employees including 3,790 at the plants
(2,100 at Portsmouth and 1,690 at Paducah) and 170 at headquarters in Bethesda,
Maryland. At the plants, 3,300 employees are involved in enrichment operations
and construction activities, and the remainder are involved primarily in
DOE-funded activities. Two labor unions represent 48% of the employees at the
plants.

ITEM 2.  PROPERTIES

    The Paducah and Portsmouth plants are among the largest industrial
facilities in the world. The process buildings at the two plants have a total
floor area of 330 acres and a ground coverage of 167 acres. Although the plants
must be continuously operated, the plants are designed so that groups of
equipment can be taken off line with little or no interruption in the process.

    The Paducah plant is located in McCracken County in western Kentucky,
consists of four process buildings, and has been in continuous operation since
September 1952. The Paducah plant has been certified by the NRC to produce low
enriched uranium up to 2.75% U(235) and has a design capacity of 11.3 million
SWU per year. Uranium enriched at the Paducah plant is shipped to the Portsmouth
plant for further enrichment.

    The Portsmouth plant is located in Pike County in south central Ohio,
consists of three process buildings, and has been in continuous operation since
1956. The plant has been certified by the NRC to produce low enriched uranium to
a maximum of 10% U(235) and has a design capacity of 7.4 million SWU per year.

    The plants are operated at levels significantly below design capacity. As
the volume of purchased SWU under the Russian Contract has increased, USEC has
operated the plants at significantly lower production levels. In addition,
production levels vary based on the cost and availability of electric power.

    USEC continuously upgrades the plants. In fiscal 1999, USEC spent $51.1
million for capital expenditures, including $21.0 million for seismic upgrades
at the Paducah plant.

    USEC leases most, but not all, of the buildings and facilities at the plants
from DOE pursuant to a lease agreement dated as of July 1, 1993 (the "Lease
Agreement"). At its sole option, USEC has the right to extend the Lease
Agreement indefinitely, with respect to either or both plants, for successive
renewal periods. In June 1997, USEC renewed the Lease Agreement for both plants
for an additional five-year term expiring on June 30, 2004. USEC may terminate
the Lease Agreement, with respect to one or both plants, by providing two years'
prior notice to DOE. USEC may increase or decrease the property under the Lease
Agreement to meet its changing requirements. Within the contiguous tracts,
certain buildings, facilities and areas related to environmental restoration and
waste management have been retained by DOE and are not leased to USEC.


                                       11
<PAGE>   12


    Lease Agreement costs include a base rent representing DOE's costs in
administering the Lease Agreement, including costs relating to administration of
the electric power contracts and costs relating to DOE's regulatory oversight of
the plants. Costs under the Lease Agreement were $2.7 million in fiscal 1999. At
termination of the Lease Agreement, USEC may leave the property in "as is"
condition, but must remove all waste generated by USEC, which is subject to
off-site removal, and must place the plants in a safe shutdown condition. DOE is
responsible for the costs of decontamination and decommissioning of the plants.
If removal of any of USEC's capital improvements increases DOE's decontamination
and decommissioning costs, USEC is required to pay such increases. Title to
capital improvements not removed by USEC will automatically be transferred to
DOE at the end of the Lease Agreement term.

    Under the Lease Agreement, DOE is required to indemnify USEC for costs and
expenses related to claims asserted against or incurred by USEC arising out of
DOE's operation, occupation or use of the plants. DOE activities at the plants
are focused primarily on environmental restoration and waste management and
management of depleted uranium. DOE is required to indemnify USEC against claims
for public liability (i) arising out of or in connection with activities under
the Lease Agreement, including domestic transportation and (ii) arising out of
or resulting from a nuclear incident or precautionary evacuation. DOE's
obligations are capped at the $9.4 billion statutory limit set forth in the
Price-Anderson Act for each nuclear incident or precautionary evacuation
occurring inside the United States.

    In addition to the plants, USEC leases its corporate headquarters office
space in Bethesda, Maryland, under a lease expiring November 2008. USEC also
leases office space in the District of Columbia.

ITEM 3.  LEGAL PROCEEDINGS

    USEC is subject to various legal proceedings and claims, either asserted or
unasserted, which arise in the ordinary course of business. While the outcome of
these claims cannot be predicted with certainty, management does not believe
that the outcome of any of these legal matters will have a material adverse
effect on USEC's results of operations or financial position.

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

    None.

April 1 to June 30, 1999 .................        14.88         9.88          .275
</TABLE>

    There are 250 million shares of common stock and 25 million shares of
preferred stock authorized. At June 30, 1999, there were 99,176,000 shares of
common stock issued and outstanding. No preferred shares have been issued. There
were approximately 39,000 beneficial holders of common stock as of June 30,
1999.

    USEC pays quarterly cash dividends on outstanding shares of common stock at
an annual rate of $1.10 per share. The quarterly dividend of $.275 per share was
paid in December 1998, March 1999 and June 1999. The declaration of dividends is
subject to the discretion of the Board of Directors and depends, among other
things, on the results of operations, financial condition, cash requirements,
any restrictions imposed by financing arrangements and any other factors deemed
relevant by the Board of Directors at that time.

    In June 1999, the Board of Directors approved a share repurchase program of
up to 10.0 million shares of common stock over 24 months. The repurchase is
being funded through internal cash flow, augmented by short-term borrowings as
needed. The Board action authorizes the purchase of shares from time to time on
the open market or through privately negotiated transactions. In fiscal 1999,
repurchases of common stock amounted to $14.8 million.

    USEC's Certificate of Incorporation (the "Charter") sets forth certain
restrictions on foreign ownership of securities, including a provision
prohibiting foreign persons (as defined in the Charter) from collectively having
beneficial ownership of more than 10% of the voting securities. The Charter also
contains certain enforcement mechanisms with respect to the foreign ownership
restrictions, including suspension of voting rights, redemption of such shares
and/or the refusal to recognize the transfer of shares on the record books of
USEC.

    USEC entered into an agreement with the U.S. Treasury Department, pursuant
to which USEC made the following commitments, among others:
      o  to abide by the Privatization Act provisions, including the provision
         which prohibits any person from acquiring more than 10% of the
         outstanding voting stock for a three-year period after the IPO Date;
         and
      o  not to sell or transfer all or substantially all of the uranium
         enrichment assets or operations of USEC during the three-year period
         after the IPO Date.

       costs and employee severance and benefit arrangements related to the
       suspension of development of the AVLIS enrichment technology. Since all
       project development costs were charged to expense, there was no asset
       write-off.

(2)    Special charges of $46.6 million in fiscal 1998 are for costs related to
       the privatization and certain severance and transition benefits in
       connection with workforce reductions at the production plants.

(3)    Prior to the IPO Date, USEC had no debt.

(4)    USEC became subject to federal, state and local income taxes at the IPO
       Date. The provision for income taxes in fiscal 1999 includes a special
       income tax benefit of $54.5 million ($.54 per share) for deferred income
       tax benefits that arise from the transition to taxable status. Excluding
       the special tax benefit, the provision for income taxes was $51.6 million
       in fiscal 1999 and reflects an effective tax rate of 34.5%.

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

    The following discussion should be read in conjunction with, and is
qualified in its entirety by reference to, the Consolidated Financial Statements
and related notes appearing elsewhere in this report.

OVERVIEW

    USEC, a global energy company, is the world leader in the sale of uranium
fuel enrichment services for commercial nuclear power plants, with approximately
73% of the North American market and approximately 35% of the world market.
Uranium enrichment is a critical step in transforming uranium into fuel for
nuclear reactors to produce electricity. Based on customers' estimates of their
requirements and certain other assumptions, including estimates of inflation
rates, at June 30, 1999, USEC had long-term requirements contracts with
utilities to provide uranium enrichment services aggregating $6.5 billion
through fiscal 2010 (including $3.3 billion through fiscal 2002) compared with
$6.9 billion at June 30, 1998.

    Agreements with electric utilities are generally long-term requirements
contracts under which customers are obligated to purchase a specified percentage
of their requirements for uranium enrichment services. Customers, however, are
not obligated to make purchases or payments if they do not have any
requirements. There is a trend for contracts with shorter terms that is expected
to continue, with the newer contracts generally containing terms in the range of
3 to 7 years.

    Revenue and operating results can fluctuate significantly from quarter to
quarter, and in some cases, year to year. Customer requirements are determined
by refueling schedules for nuclear reactors, which generally range from 12 to 18
months (or in some cases up to 24 months), and are in turn affected by, among
other things, the seasonal nature of electricity demand, reactor maintenance,
and reactors beginning or terminating operations. Utilities typically schedule
the shutdown of their reactors for refueling to coincide with the low
electricity demand periods of spring and fall. Thus, some reactors are scheduled
for fall refueling, spring refueling or for 18-month cycles alternating between
both seasons. In addition, USEC provides customers from 10 to 30 days to take
delivery of ordered product. The timing of larger orders for initial core
requirements for new nuclear reactors also can affect operating results.

    USEC is the Executive Agent of the U.S. Government under a
government-to-government agreement to purchase the SWU component of enriched
uranium recovered from dismantled nuclear weapons from the former Soviet Union
for use in commercial electricity production. Global market prices for SWU have
declined below the price being paid for SWU under the Russian Contract. USEC has
begun negotiations to align the Russian Contract with market pricing realities.
Cost of sales has been, and will continue to be, adversely affected by amounts
paid to purchase SWU under the Russian Contract; since the volume of Russian SWU
purchases has increased, USEC has operated the plants at lower production levels
resulting in higher unit production costs.

    Revenue

    Substantially all of USEC's revenue is derived from the sale of uranium
enrichment services, denominated in SWU. Although customers may buy enriched
uranium product without having to supply uranium, a significant portion of
USEC's contracts are for enriching uranium provided by customers. Because orders
for enrichment to refuel customer reactors (1) occur once in 12, 18 or 24


                                       19
<PAGE>   20



months and (2) are large in amount averaging $14.0 million per order, the
percentage of revenue attributable to any customer or group of customers from a
particular geographic region can vary significantly quarter-by-quarter or
year-by-year. However, customer requirements and orders over the longer term are
more predictable. USEC estimates that about two-thirds of the nuclear reactors
under contract operate on refueling cycles of 18 months or less, and the
remaining one-third operate on refueling cycles greater than 18 months.

    Recent industry and global economic developments have intensified the
effects of production over-capacity and continuing lower prices for SWU. These
developments include:
      o  the adverse impact of the strengthening U.S. dollar;
      o  recent decisions by certain European utilities to liquidate strategic
         SWU inventories;
      o  termination of the Kazakhstan suspension agreement; and
      o  heightened price competition among uranium enrichment suppliers.
In addition to excess production capacity, certain suppliers have announced
technology-driven plans to expand capacities.

    USEC's financial performance over time can be significantly affected by
changes in the market price for SWU. As older customer contracts expire, USEC's
backlog becomes more heavily weighted with newer contracts having lower prices.
As a result, average SWU prices have been declining.

    USEC anticipates the trend toward lower prices and shorter contract terms
will continue, due to increased competition among uranium enrichment suppliers
for new SWU commitments. As a result of these market dynamics and USEC's current
cost structure, including increased purchases under the Russian Contract, USEC
did not obtain its traditional share of new SWU commitments resulting in some
decrease in its worldwide market share. To address this trend, USEC is placing a
high priority on numerous initiatives to further reduce costs and increase
USEC's competitiveness.

    USEC's enrichment contracts are denominated in U.S. dollars, and while
revenue is not directly affected by changes in the foreign exchange rate of the
U.S. dollar, USEC may have a competitive price disadvantage or advantage
depending upon the strength or weakness of the U.S. dollar. This is because the
primary competitors' costs are denominated in the major European currencies.

    Revenue could be negatively impacted by actions of the Nuclear Regulatory
Commission suspending operations at domestic utility customer reactors under
contract with USEC. In addition, business decisions by utilities that take into
account economic factors, such as the price and availability of alternate fossil
fuels, the need for generating capacity and the cost of maintenance could result
in suspended operations or early shutdowns of some reactors under contract with
USEC.

    Cost of Sales

    Cost of sales is based on the quantity of SWU sold during the period and is
dependent upon production costs at the plants and purchase costs under the
Russian Contract. Production costs consist principally of electric power
(representing 57% of production costs in fiscal 1999), labor and benefits,
depleted uranium disposition costs, materials, and maintenance and repairs.
Under the monthly moving average inventory cost method, an increase or decrease
in production or purchase costs will have an effect on costs of sales over
future periods.


    USEC purchases a significant portion of its electric power based on
long-term contracts with dedicated power generating facilities. The cost of firm
power, which represented 70% of power



                                       20
<PAGE>   21


purchased in fiscal 1999, is based on actual costs incurred by Ohio Valley
Electric Corporation ("OVEC"), the main supplier to the Portsmouth, Ohio plant,
and Electric Energy, Inc. ("EEI"), the main supplier to the Paducah, Kentucky
plant. During certain periods, including the summer months when power costs are
typically higher, almost all of the power supplied to the Paducah plant must be
purchased at market-based rates because it is non-firm power. Depending on
inventory levels and planned shipments, USEC reduces production at the Paducah
plant when the cost of non-firm power is high. Non-firm power costs vary
seasonally with rates being higher during winter and summer as a function of the
extremity of the weather and as a function of demand during peak and off-peak
times. In the non-firm power market, prices are generally trending upward with
higher levels of volatility. Firm power costs vary depending on operating and
capital costs incurred by OVEC and EEI. Capital costs at the power generating
facilities may increase resulting in higher costs for firm power.

    USEC accrues estimated costs for the future disposition of depleted uranium
generated as a result of its operations. Costs are dependent upon the volume of
depleted uranium generated and estimated transportation, conversion and disposal
costs. USEC stores depleted uranium at the plants and continues to evaluate
various proposals for its disposition.

    USEC leases most, but not all, of the buildings and facilities at the plants
at favorable terms from DOE pursuant to a lease agreement (the "Lease
Agreement"). Upon termination of the Lease Agreement, USEC is responsible for
certain lease turnover activities at the plants. Lease turnover costs are
accrued over the estimated term of the Lease Agreement which is estimated to
extend through calendar year 2006.

    As Executive Agent under the Russian Contract, USEC purchased 3.6 million
SWU at a cost of $319.6 million, including related shipping charges, in fiscal
1999 and, subject to price adjustments for U.S. inflation, has committed to
purchase 3.9 million SWU at a cost of $333.1 million in the six months ending
December 31, 1999, and 5.5 million SWU at a cost of $469.8 million in each of
calendar years 2000 and 2001. The Russian Contract has a 20-year term.

    Project Development Costs

    In June 1999, further development of the AVLIS enrichment technology was
suspended. During fiscal 2000, USEC plans to evaluate the availability and
economics of centrifuge technology. USEC is also evaluating a potential new
advanced enrichment technology called "SILEX."

    Selling, General and Administrative

    Selling, general and administrative expenses include salaries and related
overhead for personnel, legal and consulting fees and other administrative
costs.

    Income Taxes

    USEC became subject to federal and state income taxes at the IPO Date with
an effective income tax rate of 34.5% in fiscal 1999.

     special tax benefit for deferred income taxes that arise from the
     transition to taxable status.

RESULTS OF OPERATIONS -- FISCAL YEARS ENDED JUNE 30, 1999 AND 1998

    Revenue

    Revenue amounted to $1,528.6 million in fiscal 1999, an increase of $107.4
million (or 8%) from $1,421.2 million in fiscal 1998. Revenue from sales of SWU
increased $94.6 million (7%) in fiscal 1999 reflecting the timing of customer
nuclear reactor refueling orders, including sales to customer reactors returning
to service following an extended outage, partly offset by lower SWU commitment
levels of a domestic and a foreign customer. USEC provided enrichment services
for 108 reactors in fiscal 1999, compared with 100 reactors in fiscal 1998. The
average SWU price billed to customers in fiscal 1999 was about the same as in
fiscal 1998.

    Revenue from domestic customers increased $51.4 million (or 6%), revenue
from customers in Asia increased $12.4 million (or 3%) and revenue from
customers in Europe and other areas increased $43.6 million (or 53%). The
increases in the geographic mix of revenue in fiscal 1999 resulted primarily
from the timing of customers' orders, and the increase in domestic revenue
reflects sales to customer reactors returning to service following an extended
outage.

    Revenue from sales of uranium was $53.6 million in fiscal 1999, an increase
of $12.8 million (or 31%) from $40.8 million in fiscal 1998. Certain contracts
with customers provided for the sale of uranium and SWU in the form of enriched
uranium product.



                                       22
<PAGE>   23


    During fiscal 1999, USEC signed contracts for $1.3 billion in new business
for delivery over the next 10 years. As a result of lower prices, shorter
contract terms, and the variability of customer orders, management expects
fiscal year 2000 revenue to be about $1.4 billion, compared with $1.5 billion in
fiscal 1999.

    Cost of Sales

    Cost of sales amounted to $1,182.0 million in fiscal 1999, an increase of
$119.9 million (or 11%) compared with $1,062.1 million in fiscal 1998. The
increase in cost of sales in fiscal 1999 reflects the 7% increase in sales of
SWU, primarily from the timing of customer orders, and the effects under the
monthly moving average inventory cost method of lower production levels and
higher unit production costs at the plants in fiscal 1999 and 1998. In fiscal
1999, production costs were affected by high power costs in the summer and early
fall of 1998. As a percentage of revenue, cost of sales amounted to 77% in
fiscal 1999, compared with 75% in fiscal 1998.

    Electric power costs amounted to $436.4 million in fiscal 1999 (representing
57% of production costs) compared with $413.8 million (representing 53% of
production costs) in fiscal 1998. The increase was attributable to higher costs
per megawatt hour ("MWh"), partly offset by $31.7 million from the monetization
of excess power. The average price of electric power purchased was $21.54 per
MWh in fiscal 1999 compared with $19.66 per MWh in fiscal 1998. In the summer
and early fall of 1998, persistent hot weather, high electricity demand in the
Midwest and power generation shortages resulted in record high power costs at
the Paducah plant. USEC curtailed production at the Paducah plant during the
summer and early fall of 1998 to reduce the impact of high power prices.

    An agreement increasing flexibility under the contract with EEI and a
six-month financial and supply agreement with OVEC were approved by regulatory
authorities. The changes USEC negotiated in fiscal 1999 to its power supply
agreements with its two primary and other electric power suppliers include
provisions:
      o  limiting exposure to high-cost, non-firm power prices at the Paducah
         plant in the summer of 1999;
      o  monetizing excess power available in the summer of 1999 under the
         contract to the Portsmouth plant; and
      o  being able to move blocks of power in the summer of 1999 from the
         Portsmouth plant to the Paducah plant.

    USEC intends to negotiate with OVEC to extend and expand these provisions
beyond the summer of 1999. In the non-firm power market, prices are generally
trending upward. USEC intends to manage its production levels and power
purchases to reduce exposure to the continuing fluctuations in non-firm power
prices, although there can be no assurance that USEC will be successful in
reducing such exposure.

    Costs for labor and benefits amounted to $238.9 million in fiscal 1999,
about the same as in fiscal 1998. Consistent with the agreement with the U.S.
Treasury, the average number of employees at the plants declined 7% in fiscal
1999, and is expected to decline 8% in fiscal 2000.


    Prior to May 18, 1999, Lockheed Martin Utility Services ("LMUS"), a
subsidiary of Lockheed Martin Corporation, provided labor, services, and
materials and supplies to operate and maintain the plants under an operations
and maintenance contract. USEC funded LMUS for actual costs incurred and
contract fees. USEC has indemnified LMUS for certain liabilities associated with
performance of the operations and maintenance contract for the term of the
contract. In this regard, the



                                       23
<PAGE>   24


Privatization Act generally provides that liabilities attributable to plant
operations prior to July 28, 1998, remain liabilities of the U.S. Government.
Effective May 18, 1999, USEC terminated the contract and assumed direct
management and operation of the plants. Plant workers became employees of USEC.

    Costs for the future disposition of depleted uranium amounted to $40.5
million in fiscal 1999, a decline of $15.2 million (or 27%) from $55.7 million
in fiscal 1998. The reduction reflects a lower future disposal rate per kilogram
of depleted uranium based on fixed-cost disposal contracts for a certain
quantity of depleted uranium. Pursuant to the USEC Privatization Act, depleted
uranium generated by USEC through the IPO Date was transferred to DOE, and the
accrued liability of $373.8 million at the IPO Date was transferred to
stockholders' equity.

    At the Portsmouth plant, SWU unit production costs were adversely affected
in fiscal 1999 and 1998 by low production facility capability due to continued
sub-optimal gaseous diffusion production equipment availability.

    SWU purchased from the Russian Federation represented 31% of the combined
produced and purchased supply mix in fiscal 1999 compared with 38% purchased
from the Russian Federation and DOE in fiscal 1998. In March 1999, the Russian
Federation resumed deliveries after several months of suspended deliveries. The
suspended schedule of 1998 calendar year deliveries to USEC was completed in
June 1999, and USEC has agreed to a schedule of deliveries for the remainder of
calendar year 1999. Purchases from the Russian Federation are expected to
aggregate 5.7 million SWU in calendar 1999, of which 1.8 million SWU had been
purchased as of June 30, 1999. Cost of sales has been, and will continue to be,
affected by amounts paid to purchase SWU under the Russian Contract; since the
volume of SWU purchases has increased, USEC has operated the plants at
significantly lower production levels resulting in higher unit production costs.

    Gross Profit

    Gross profit amounted to $346.6 million in fiscal 1999, a reduction of $12.5
million (or 4%) from $359.1 million in fiscal 1998. Although revenue increased
8% compared with fiscal 1998, gross margins declined from 25% to 23% in fiscal
1999. The lower production levels and higher unit production costs at the plants
in fiscal 1999 and 1998 contributed to the lower gross profit in fiscal 1999.

    Special Charges - Suspension of Development of AVLIS Technology

    In June 1999, further development of the AVLIS enrichment technology was
suspended. In connection with a comprehensive review of operating and economic
factors, USEC reexamined the AVLIS technology, performance, prospects, risks and
growing financial requirements as well as the economic impact of competitive
marketplace dynamics and concluded that the returns were not sufficient to
outweigh the risks and ongoing capital expenditures necessary to develop and
construct an AVLIS plant.

    Special charges amounted to $34.7 million ($22.7 million or $.23 per share
after tax) in fiscal 1999 for contract terminations, shutdown activities and
employee severance and benefit arrangements related to the suspension in June
1999 of development of the AVLIS enrichment technology. It is expected that
substantially all of the shutdown activities will be completed within one year.
Since all project development costs were charged to expense, there was no asset
write-off.

    Special Charges - Workforce Reductions and Privatization Costs

    Special charges amounted to $46.6 million in fiscal 1998 for costs related
to the privatization and certain severance and transition benefits to be paid to
plant workers in connection with workforce reductions, as follows (millions):

                                                                 =====
</TABLE>

    Privatization costs of $13.8 million were paid in July 1998, worker and
community transition assistance benefits of $20.0 million were paid to DOE in
June 1998, and payments of $5.9 million for workers' pre-existing severance
benefits with respect to 312 workers had been made as of June 30, 1999.

    Project Development Costs

    Project development costs, primarily for the AVLIS project, amounted to
$106.4 million in fiscal 1999, a decline of $30.3 million (or 22%) from $136.7
million in fiscal 1998. In June 1999, further development of the AVLIS
enrichment technology was suspended.

    Operating Income

    Operating income amounted to $165.2 million in fiscal 1999, an increase of
$24.1 million (or 17%), compared with $141.1 million in fiscal 1998. Operating
income was reduced by a special charge of $34.7 million in fiscal 1999 for the
suspension of AVLIS technology and $46.6 million in fiscal 1998 for workforce
reductions and privatization costs. Project development costs were $30.3 million
lower and gross profit was $12.5 million lower in fiscal 1999.

    Interest Expense

    Interest expense of $32.5 million in fiscal 1999 represents interest on
senior notes issued in January 1999, borrowings under the bank credit facility,
and short-term borrowings under a commercial paper program established in
February 1999. Prior to the IPO Date, USEC had no debt.

    Other Income

    Other income of $16.8 million in fiscal 1999 includes a nonrecurring gain of
$8.2 million from a contract modification canceling accrued interest payable on
an advance payment from the Arab Republic of Egypt.

    Provision for Income Taxes

    USEC became subject to federal, state and local income taxes at the IPO
Date. The provision for income taxes in fiscal 1999, includes a special income
tax benefit of $54.5 million ($.54 per share) for deferred income tax benefits
that arise from the transition to taxable status. Deferred tax benefits
represent differences between the carrying amounts for financial reporting
purposes and USEC's estimate of the tax bases of its assets and liabilities.



                                       25
<PAGE>   26


    Excluding the special tax benefit, the provision for income taxes in fiscal
1999 amounted to $51.6 million and reflects an effective income tax rate of
34.5%.

    Net Income

    Net income excluding special items was $120.6 million (or $1.21 per share)
in fiscal 1999 and $192.9 million in fiscal 1998. The reduction reflects income
taxes and interest expense incurred since the IPO in July 1998. Including
special items, net income was $152.4 million (or $1.52 per share) in fiscal 1999
and $146.3 million in fiscal 1998.

    Fiscal 2000 Outlook

    In light of recent industry and global economic developments that have
intensified the effects of production over-capacity and continuing low prices
for enrichment services, management is actively reviewing USEC's cost structure
and strategic alternatives to bolster USEC's competitive position over the
longer term. Management believes that this process will result in initiatives
directed at better rationalizing worldwide excess production capacity and
aligning the Russian Contract with market pricing realities. Innovative
marketing initiatives are underway to achieve additional sales.

    Through aggressive cost cutting actions, management expects fiscal 2000
earnings to be similar to the fiscal 1999 level, excluding special items, with
continued strong cash flow.

RESULTS OF OPERATIONS -- FISCAL YEARS ENDED JUNE 30, 1998 AND 1997

    Revenue

    Revenue amounted to $1,421.2 million in fiscal 1998, a decline of $156.6
million (or 10%) from $1,577.8 million in fiscal 1997. The decline in revenue
was attributable primarily to the timing of customer nuclear reactor refuelings
resulting in a 12% decline in sales of SWU in fiscal 1998, following a 14%
increase in fiscal 1997. During fiscal 1998, USEC provided enrichment services
for 100 reactors as compared with 110 in fiscal 1997. The average SWU price
billed to customers increased approximately 1% compared with fiscal 1997,
notwithstanding the overall trend toward lower prices for contracts negotiated
since July 1993 in the highly competitive uranium enrichment market. Sales of
uranium to electric utility customers increased to $40.8 million, compared with
$25.9 million in fiscal 1997.

    Revenue from domestic customers declined $54.6 million (or 6%), revenue from
customers in Asia declined $44.7 million (or 9%) and revenue from customers in
Europe and other areas declined $57.3 million (or 41%). Changes in the
geographic mix of revenue in fiscal 1998 resulted primarily from the timing of
customers' orders. The decline in domestic revenue also reflects lower
commitment levels from two customers, partially offset by higher sales of
uranium and a first time sale of SWU for one reactor.

    Cost of Sales

    Cost of sales amounted to $1,062.1 million in fiscal 1998, a decline of
$100.2 million (or 9%) from $1,162.3 million in fiscal 1997. The decline in cost
of sales was attributable to the 12% decline in sales in SWU from the timing of
customers' orders, partially offset by the effects of lower production volume
and higher unit costs at the plants and an increase in purchased SWU under the



                                       26
<PAGE>   27


Russian Contract. As a percentage of revenue, cost of sales amounted to 75% in
fiscal 1998, compared with 74% in fiscal 1997.

    SWU unit production costs in fiscal years 1998 and 1997 were adversely
affected by lower production facility capability, and USEC incurred additional
costs because uneconomic overfeeding of uranium was necessary at the Portsmouth
plant to compensate for the production lost due to the unavailability of
production equipment in order to ensure that customer requirements would be met.

    Electric power costs amounted to $413.8 million (representing 53% of
production costs) in fiscal 1998, compared with $530.4 million (representing 59%
of production costs) in fiscal 1997, a decline of $116.6 million (or 22%). The
decline reflected lower power consumption resulting from lower SWU production
and improved power utilization efficiency, or SWU production compared with the
amount of electric power consumed.

    Costs for labor and benefits amounted to $237.7 million in fiscal 1998, an
increase of $7.6 million (or 3%) from $230.1 million in fiscal 1997. The
increase reflected general inflation.

    Costs for the future disposition of depleted uranium amounted to $55.7
million in fiscal 1998, a decline of $16.3 million (or 23%) from $72.0 million
in fiscal 1997. The decline resulted from lower SWU production overall and, at
the Paducah plant, more efficient operations and economic underfeeding of
uranium which in turn resulted in a significant reduction in the generation of
depleted uranium.

    SWU purchased under the Russian Contract and other purchase contracts
represented 38% of the combined produced and purchased supply mix, compared with
23% for fiscal 1997. Unit costs of SWU purchased under the Russian Contract are
substantially higher than USEC's marginal cost of production. USEC purchased SWU
derived from highly enriched uranium, as follows: 3.6 million SWU at a cost of
$315.8 million and 1.8 million SWU at a cost of $157.3 million in fiscal years
1998 and 1997, respectively.

    Gross Profit

    Gross profit amounted to $359.1 million in fiscal 1998, a decline of $56.4
million (or 14%) from $415.5 million in fiscal 1997. The decline resulted from
lower sales of SWU from the timing of customers' orders, lower production volume
and higher unit costs at the plants, and an increase in purchased SWU under the
Russian Contract.

    Special Charges - Workforce Reductions and Privatization Costs

    Special charges amounted to $46.6 million in fiscal 1998 for costs related
to the privatization and certain severance and transition benefits to be paid to
plant workers in connection with workforce reductions.

    Project Development Costs

    Project development costs, primarily for the AVLIS project, amounted to
$136.7 million for fiscal 1998, a decline of $4.8 million (or 3%) from $141.5
million in fiscal 1997. Engineering and development costs for the AVLIS uranium
enrichment process in fiscal 1998 primarily reflected continuing demonstration
of plant-scale components with emphasis shifting toward integrated operation of
the laser and separator systems to verify enrichment production economics.
Project



                                       27
<PAGE>   28


development costs include costs of $2.0 million in fiscal 1998 and $7.8 million
in fiscal 1997 incurred in the evaluation of the SILEX advanced enrichment
technology.

    Selling, General and Administrative Expenses

    Selling, general and administrative expenses amounted to $34.7 million in
fiscal 1998, an increase of $2.9 million (or 9%) from $31.8 million in fiscal
1997. As a percentage of revenue, selling, general and administrative expenses
amounted to 2.4% in fiscal 1998, compared with 2.0% in fiscal 1997. The increase
resulted from higher expenses associated with privatization activities.

    Net Income

    Net income before special charges amounted to $192.9 million in fiscal 1998,
a decline of $57.2 million (or 23%) from $250.1 million in fiscal 1997. As a
percentage of revenue, net income before special charges amounted to 13% in
fiscal 1998, compared with 16% in fiscal 1997. The decline resulted primarily
from lower sales of SWU from the timing of customers' orders and lower gross
profit margins. Including special charges, net income in fiscal 1998 amounted to
$146.3 million.

LIQUIDITY AND CAPITAL RESOURCES

    Liquidity and Cash Flow

    Net cash flows provided by operating activities amounted to $230.4 million
in fiscal 1999, compared with $73.3 million in fiscal 1998. Cash flow in fiscal
1999 includes the collection of an overdue receivable of $36.0 million from a
Korean customer, an increase of $24.1 million in operating income, an increase
of $38.4 million in current liabilities for income taxes and $34.2 million for
the suspension of development of the AVLIS technology, and an increase in
long-term liabilities of $24.8 million for depleted uranium disposition, partly
offset by interest expense of $32.5 million on borrowings in fiscal 1999. In
fiscal 1999, receivables increased $137.4 million, inventories increased $51.2
million, and net payables under the Russian Contract increased $78.0 million.

    Net cash flows provided by operating activities amounted to $73.3 million in
fiscal 1998, compared with $356.1 million in fiscal 1997. Cash flow in fiscal
1998 was reduced by an increase of $142.5 million in inventories, the decline of
$103.8 million in net income compared with fiscal 1997, and payments of $66.0
million in fiscal 1998 to DOE relating to the disposition of depleted uranium,
partly offset by an increase of $64.4 million in payables to the Russian
Federation for purchases of SWU.

    Capital expenditures amounted to $25.8 million, $36.5 million and $51.1
million in fiscal years 1997, 1998 and 1999, respectively. Capital expenditures
in fiscal 1999 include costs of $21.0 million for seismic upgrades at the
Paducah plant, required by the NRC Compliance Plan, to reduce the risk of
release of radioactive and hazardous material in the event of an earthquake. In
fiscal 2000, USEC expects its capital expenditures will approximate $61.0
million, including costs to complete the seismic upgrades and to upgrade the
Paducah plant's capability to produce enriched uranium up to 5% U(235).

    In June 1999, the Board of Directors approved a share repurchase program of
up to 10.0 million shares of common stock over 24 months. The repurchase is
being funded through internal cash flow, augmented by short-term borrowings as
needed. The Board action authorizes the purchase of shares



                                       28
<PAGE>   29


from time to time on the open market or through privately negotiated
transactions. In fiscal 1999, repurchases of common stock amounted to $14.8
million.

    In December 1998, March 1999 and June 1999, quarterly cash dividends of
$.275 per share were paid to shareholders and aggregated $82.5 million. On July
28, 1999, a cash dividend of $.275 was declared, payable September 15, 1999, to
shareholders of record August 27, 1999.

    The sale of USEC's common stock in connection with the IPO resulted in net
proceeds to the U.S. Government aggregating $3,092.1 million and consisting of
(1) net proceeds of $1,882.7 million from the initial public offering of
$1,382.7 million and borrowings of $500.0 million paid to the U.S. Government,
and (2) cash of $1,209.4 million paid to the U.S. Government as part of the exit
dividend. The U.S. Government, the selling shareholder, sold its entire
interest. USEC did not receive any proceeds from the IPO.

    Cash dividends paid to the U.S. Treasury amounted to $120.0 million in each
of the fiscal years 1997 and 1998.

    Capital Structure and Financial Resources

    On January 20, 1999, USEC issued $350.0 million of 6.625% senior notes due
January 2006 and $150.0 million of 6.750% senior notes due January 2009. The net
proceeds of $495.2 were used to repay a portion of the borrowings under a bank
credit facility. The senior notes are unsecured obligations and rank on a parity
with all other unsecured and unsubordinated indebtedness of USEC Inc.

    Commitments available under bank credit facilities total $300.0 million as
follows: $150.0 million under a revolving credit facility convertible in July
2000 into a one-year term loan and $150.0 million under a revolving credit
facility expiring July 2003. Commercial paper borrowings of $50.0 million
included in short-term debt at June 30, 1999, are supported by available
commitments under the bank credit facilities.

    At June 30, 1999, net working capital amounted to $943.3 million, including
net inventories of $831.7 million, and the total debt-to-capitalization ratio
was 33%.

    USEC expects that its cash, internally generated funds from operating
activities, and available financing sources under the bank credit facilities and
commercial paper program, will be sufficient to meet its obligations as they
become due and to fund operating requirements of the plants, purchases of SWU
under the Russian Contract, capital expenditures and discretionary investments,
interest expense, quarterly dividends, and repurchases of common stock.

ENVIRONMENTAL MATTERS

    In addition to costs for the future disposition of depleted uranium, USEC
incurs operating costs and capital expenditures for matters relating to
compliance with environmental laws and regulations, including the handling,
treatment and disposal of hazardous, low-level radioactive and mixed wastes
generated as a result of its operations. Operating costs were $24.9 million,
$25.4 million and $24.1 million and capital expenditures were $1.8 million, $4.4
million and $3.1 million in fiscal years 1997, 1998 and 1999, respectively. In
fiscal years 2000 and 2001, USEC expects its operating costs and capital
expenditures for environmental matters to remain at about the same levels as in
fiscal 1999.

    Costs for the future treatment and disposal of depleted uranium produced
from operations were $40.5 million in fiscal 1999. USEC paid $50.0 million to
DOE in fiscal 1998 in consideration for DOE assuming responsibility for a
certain amount of depleted uranium generated by USEC from October 1998 to
September 2005.

    Environmental liabilities associated with plant operations prior to July 28,
1998, are the responsibility of the U.S. Government, except for liabilities
relating to certain identified wastes generated by USEC and stored at the
plants. DOE remains responsible for decontamination and decommissioning of the
plants.

CHANGING PRICES AND INFLATION

    The plants require substantial amounts of electric power to enrich uranium.
Information with respect to electric power prices and costs is included above.

    A majority of USEC's long-term requirements contracts with customers
generally provide for prices that are subject to adjustment for inflation.

IMPACT OF YEAR 2000 ISSUE

    The Year 2000 issue exists because many software and embedded systems
(defined below), which use only two digits to identify a year in a date field,
were developed without considering the impact of the upcoming change in the
century. Some of these systems are critical to USEC's operations and business
processes and could fail or function inaccurately if not repaired or replaced
with Year 2000 ready products.

    USEC's software and embedded systems will be Year 2000 ready when such
systems are replaced or remediated to perform essential functions accurately and
without failure. Software is computer programming that has been developed by
USEC for its own use (in-house software) and purchased from vendors (vendor
software). Embedded systems refer to both computing hardware and other
electronic monitoring, communications, and control systems that have
microprocessors.

     The Year 2000 project focuses on systems that are critical. The failure of
critical systems would directly and adversely affect the ability to generate or
deliver products and services or otherwise affect revenue, safety, or
reliability for a period of time as to lead to unrecoverable consequences. USEC
adopted a phased approach for critical systems:
      o  a company-wide inventory, in which critical systems were identified;
      o  assessment, in which critical systems were evaluated as to their
         readiness to operate in the Year 2000;
      o  remediation, in which critical systems that were not Year 2000 ready
         were upgraded by modification or replacement;
      o  testing, in which remediation was validated by checking the ability of
         critical systems to operate within the Year 2000 time frame; and
      o  certification, in which systems were formally acknowledged to be Year
         2000 ready and acceptable for operation.

    In July 1999, remediation, testing and certification of the identified,
critical, in-house and vendor software and hardware was complete.

                                       30
<PAGE>   31


    Remediated software and embedded systems were tested both for ability to
handle Year 2000 dates, including leap year, and to assure that repair had not
affected functionality. Software and embedded systems were tested individually
and where necessary in an integrated manner with other systems, with dates
advanced to simulate the Year 2000. Testing reduces risk, but cannot
comprehensively address all future combinations of dates and events.

    As required by the NRC, USEC has completed its program to assure that
systems required for safe and compliant operations of the plants are Year 2000
ready.

    USEC depends on external parties, including electric power utilities,
customers, suppliers, government agencies, and financial institutions, to
reliably deliver products and services. To the extent that external parties
experience Year 2000 problems, the demand for and the reliability of USEC's
services may be adversely affected. USEC has adopted a phased approach to
address external parties and the Year 2000 issue:
      o  inventory, in which critical business relationships were identified;
      o  action planning, in which a series of actions and a time frame for
         monitoring expected compliance status were developed;
      o  assessment, in which the likelihood of external party Year 2000
         readiness is being evaluated; and
      o  contingency planning, in which plans are being made to deal with the
         potential failure of an external party to be Year 2000 ready.

    Assessment of Year 2000 readiness of external parties and contingency
planning will continue through calendar year 1999.

    USEC recognizes that, given the complex interaction of computing and
communication systems, it is not possible to be certain that all efforts to have
all critical systems Year 2000 ready will be successful. There can be no
assurance that such programs will identify and cure all software problems, or
that entities on whom USEC relies for certain services integral to its business,
such as the electric power suppliers, will successfully address all of their
software and systems problems in order to operate without disruption in 2000.
Contingency plans are being developed and will be continually evaluated and
revised through the remainder of calendar year 1999. Contingency planning
includes, but is not limited to, the development of plans in the event that
electric power is interrupted or reduced for an extended period of time, the
continued communication with critical suppliers to ensure their Year 2000
readiness, and the identification of alternative suppliers, vendors and service
providers.

    Costs for software modifications and systems upgrades to resolve Year 2000
issues aggregated $11.9 million at June 30, 1999, and additional costs of $.5
million are expected in fiscal 2000. Pursuant to USEC's financial accounting and
reporting policies, purchased hardware and software costs are capitalized, and
implementation costs, including consultants' fees, are charged against income as
incurred.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To USEC Inc.:

    We have audited the accompanying consolidated balance sheets of USEC Inc. (a
Delaware Corporation) as of June 30, 1998 and 1999, and the related consolidated
statements of income and cash flows for each of the three years in the period
ended June 30, 1999. 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, the financial statements referred to above present fairly,
in all material respects, the financial position of USEC Inc. as of June 30,
1998 and 1999, and the results of its operations and its cash flows for each of
the three years in the period ended June 30, 1999, in conformity with generally
accepted accounting principles.

                                    USEC INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS

    USEC Inc., a Delaware corporation ("USEC"), formerly United States
Enrichment Corporation (a U.S. Government-owned corporation), is a global energy
company and is the world leader in the sale of uranium enrichment services for
use in nuclear power plants. USEC provides uranium enrichment services to
approximately 60 electric utilities for use in about 170 nuclear reactors.

    Customers typically deliver uranium to the enrichment facilities to be
processed or enriched under enrichment contracts. Customers are billed for
Separative Work Units ("SWU") used at the enrichment facilities to separate
specific quantities of uranium containing .711% of U(235) into two components:
enriched uranium having a higher percentage of U(235) and depleted uranium
having a lower percentage of U(235).

    USEC uses the gaseous diffusion process to enrich uranium, separating and
concentrating the lighter uranium isotope U(235) from its slightly heavier
counterpart U(238). The process relies on the slight difference in mass between
the isotopes for separation. At the leased gaseous diffusion plants ("plants")
located near Portsmouth, Ohio, and in Paducah, Kentucky, the concentration of
the isotope U(235) is raised from less than 1% to up to 5%. A substantial
portion of the purchased power used by the plants is supplied under power
contracts between the U.S. Department of Energy ("DOE") and Ohio Valley Electric
Corporation ("OVEC") and Electric Energy, Inc. ("EEI").

    The Nuclear Regulatory Commission has had regulatory authority over the
operations of the plants since March 1997. The term of the Nuclear Regulatory
Commission certification of the plants has been renewed for a five-year period
ending December 2003.

    USEC has been designated by the U.S. Government as the Executive Agent under
a government-to-government agreement and as such entered into an agreement with
the executive agent for the Russian Federation (the "Russian Contract") under
which USEC purchases SWU derived from highly enriched uranium recovered from
dismantled nuclear weapons of the Russian Federation for use in commercial
electricity production.

    The sale of USEC's common stock in connection with the initial public
offering ("IPO") was completed on July 28, 1998 (the "IPO Date"), resulting in
net proceeds to the U.S. Government aggregating $3,092.1 million and consisting
of (1) net proceeds of $1,882.7 million from the initial public offering of
$1,382.7 million and borrowings of $500.0 million paid to the U.S. Government,
and (2) cash of $1,209.4 million paid to the U.S. Government as part of the exit
dividend. The U.S. Government, the selling shareholder, sold its entire
interest. USEC did not receive any proceeds from the IPO.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CONSOLIDATION

    In connection with the IPO, USEC Inc. became a holding company. The
consolidated financial statements include the accounts of USEC Inc. and its
subsidiaries. All material intercompany transactions have been eliminated.

CASH AND CASH EQUIVALENTS

    Cash and cash equivalents at June 30, 1999, include temporary cash
investments with maturities of three months or less. At June 30, 1998, cash
consisted of non-interest bearing funds on deposit with the U.S. Treasury.

INVENTORIES

    Inventories of SWU and uranium are valued at the lower of cost or market
with market for SWU based on the terms of long-term contracts with customers.
SWU inventory costs are determined using the monthly moving average cost method
and are based on production costs at the plants and SWU purchase costs, mainly
under the Russian Contract. Production costs at the plants include purchased
electric power, labor and benefits, depleted uranium disposition costs,
materials, maintenance and repairs, and other costs. Purchased SWU is recorded
at acquisition cost plus related shipping costs.

PROPERTY, PLANT AND EQUIPMENT

    Construction work in progress is recorded at acquisition or construction
cost. Upon being placed into service, costs are transferred to leasehold
improvements or machinery and equipment at which time depreciation commences.
Leasehold improvements and machinery and equipment are recorded at acquisition
cost and depreciated on a straight line basis over the shorter of their useful
lives which range from three to ten years or the expected plant lease period
which is estimated to extend through calendar year 2006. USEC leases the plants
and process-related machinery and equipment from DOE. At the end of the lease
term, ownership and responsibility for decontamination and decommissioning of
property, plant and equipment that USEC leaves at the plants transfer to DOE.

    Property, plant and equipment at June 30 consists of the following (in
millions):

REVENUE

    Revenue is recognized at the time SWU or uranium is shipped under the terms
of contracts with domestic and foreign electric utility customers. Under
delivery optimization and other customer oriented programs, USEC advance ships
enriched uranium to nuclear fuel fabricators for scheduled or anticipated orders
from utility customers. Revenue from sales of SWU under such programs is
recognized as title to enriched uranium is transferred to customers. Under
certain power-for-SWU barter contracts, USEC exchanges its enrichment services
for electric power supplied to the plants. Revenue is recognized at the time
enriched uranium is shipped with selling prices for SWU based on the fair market
value of electric power received. No customer accounted for more than 10% of
revenue during the years ended June 30, 1997, 1998 or 1999. Revenue attributed
to domestic and international customers follows:

</TABLE>

    Under the terms of certain enrichment contracts, customers make partial or
full payment in advance of delivery. Advances from customers are reported as
liabilities, and, as customers take delivery, advances are recorded as revenue.

FINANCIAL INSTRUMENTS

    The balance sheet carrying amounts for cash and cash equivalents, accounts
receivable, accounts payable and accrued liabilities, and payables under the
Russian Contract approximate fair value because of the short-term nature of the
instruments (see Note 6).

CONCENTRATIONS OF CREDIT RISK

    Credit risk could result from the possibility of a customer failing to
perform according to the terms of a contract. Extension of credit is based on an
evaluation of each customer's financial condition. USEC regularly monitors
credit risk exposure and takes steps to mitigate the likelihood of such exposure
resulting in a loss. Based on experience and outlook, an allowance for bad debts
has not been established for customer trade receivables.

ENVIRONMENTAL COSTS

    Environmental costs relating to operations are charged to production costs
as incurred. Estimated future environmental costs, including depleted uranium
disposition and waste disposal, resulting from operations where environmental
assessments indicate that storage, treatment or disposal is probable and costs
can be reasonably estimated, are accrued and charged to production costs.

PROJECT DEVELOPMENT COSTS

    Project development costs relate principally to the Atomic Vapor Laser
Isotope Separation project ("AVLIS"). AVLIS development costs are charged to
expense as incurred and include activities relating to the design and testing of
process equipment and the design and preparation of the AVLIS demonstration
facility. In June 1999, further development of the AVLIS technology was
suspended (see Note 7).



                                      F-8
<PAGE>   46


    Project development costs relating to a potential new advanced enrichment
technology called SILEX are charged to expense as incurred.

INCOME TAXES

    USEC became subject to federal, state and local income taxes at the IPO
Date. Future tax consequences of temporary differences between the carrying
amounts for financial reporting purposes and USEC's estimate of the tax bases of
its assets and liabilities result in deferred income tax benefits primarily due
to the accrual of certain costs included in other liabilities.

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,
disclosure of contingent assets and liabilities at the date of the financial
statements, and reported amounts of revenue and costs and expenses during the
periods presented. Estimates include costs for the disposition of depleted
uranium, lease turnover costs, decommissioning and shutdown costs for power
generating facilities, the operating lease period of the plants, and employee
benefits, among others. Actual results could differ from those estimates.

RECLASSIFICATIONS

    Certain amounts in the consolidated financial statements have been
reclassified to conform with the current presentation.

</TABLE>

    Inventories included in current assets represent amounts required to meet
working capital needs, preproduce enriched uranium and balance the uranium and
electric power requirements of the plants, and include $187.6 million and $56.4
million at June 30, 1998 and 1999, respectively, for enriched uranium held at
nuclear fuel fabricators and other locations and scheduled to be used to fill
customer orders.

    Generally, title to uranium provided by customers for enrichment purposes
does not pass to USEC. Uranium provided by customers for which title does pass
to USEC is recorded on the balance sheet at estimated fair values of $315.0
million and $101.7 million at June 30, 1998 and 1999, respectively, with a
corresponding liability in the same amount representing uranium owed to
customers.

<PAGE>   47


    Inventories reported as long-term assets represent quantities not expected
to be used or sold within one year of the balance sheet date. USEC anticipates
selling uranium gradually as natural uranium or together with SWU in the form of
enriched uranium product over the next several years. USEC intends to manage
sales of natural uranium so as to not significantly affect the U.S. market.

4. PURCHASE OF SEPARATIVE WORK UNITS UNDER RUSSIAN CONTRACT

    In January 1994, USEC on behalf of the U.S. Government signed the 20-year
Russian Contract with AO Techsnabexport ("Tenex"), the Executive Agent for the
Russian Federation, under which USEC purchases SWU derived from up to 500 metric
tons of highly enriched uranium recovered from dismantled Soviet nuclear
weapons. Highly enriched uranium is blended down in Russia and delivered to
USEC, F.O.B. St. Petersburg, Russia, for sale and use in commercial nuclear
reactors.

    From inception of the Russian Contract to June 30, 1999, USEC purchased 11.0
million SWU derived from 60 metric tons of highly enriched uranium at an
aggregate cost of $959.5 million, including related shipping charges, as follows
(in millions):

    Over the life of the Russian Contract, USEC expects to purchase 92 million
SWU derived from 500 metric tons of highly enriched uranium. Assuming actual
prices in effect at June 30, 1999, were to prevail over the remaining life of
the contract, the cost of SWU purchased and expected to be purchased would
amount to approximately $8 billion.

    As of June 30, 1999, the remaining balance of $50.0 million paid to Tenex as
credits for future SWU deliveries is scheduled to be applied during the six
months ending December 31, 1999.

                                                       ========
</TABLE>

    On January 20, 1999, USEC issued $350.0 million of 6.625% senior notes due
January 2006 and $150.0 million of 6.750% senior notes due January 2009. The net
proceeds of $495.2 million were used to repay a portion of the borrowings under
a bank credit facility. The senior notes are unsecured obligations and rank on a
parity with all other unsecured and unsubordinated indebtedness of USEC Inc. The
senior notes are not subject to any sinking fund requirements. Interest is paid
every six months on January 20 and July 20 beginning in July 1999. The senior
notes may be redeemed at any time at a redemption price equal to the principal
amount plus any accrued interest up to the redemption date plus a make-whole
premium, as defined.

    Commitments available under bank credit facilities total $300.0 million as
follows: $150.0 million under a revolving credit facility convertible in July
2000 into a one-year term loan and $150.0 million under a revolving credit
facility expiring July 2003. A commercial paper program was established in
February 1999. Commercial paper borrowings of $50.0 million included in
short-term debt at June 30, 1999, are supported by available commitments under
the bank credit facilities.

    The bank credit facilities require USEC to comply with certain financial
covenants, including a minimum net worth and a debt to total capitalization
ratio, as well as other customary conditions and covenants. The bank credit
facility restricts borrowings by subsidiaries to a maximum of $100.0 million.
The failure to satisfy any of the covenants would constitute an event of
default. The bank credit facilities also include other customary events of
default, including without limitation, nonpayment, misrepresentation in a
material respect, cross-default to other indebtedness, bankruptcy and change of
control.

    At June 30, 1999, the fair value of debt calculated based on a spread over
U.S. Treasury securities with similar maturities was $521.6 million, compared
with the balance sheet carrying amount of $550.0 million.

7. SPECIAL CHARGES

SUSPENSION OF DEVELOPMENT OF AVLIS TECHNOLOGY

    AVLIS is a uranium enrichment process which uses lasers to separate uranium
isotopes. The AVLIS process was developed under a contract with DOE by the
Lawrence Livermore National Laboratory ("LLNL") located in Livermore,
California.

    In June 1999, further development of the AVLIS enrichment technology was
suspended. In connection with a comprehensive review of operating and economic
factors, USEC reexamined the AVLIS technology, performance, prospects, risks and
growing financial requirements as well as the economic impact of competitive
marketplace dynamics and concluded that the returns were not sufficient to
outweigh the risks and ongoing capital expenditures necessary to develop and
construct an AVLIS plant.



                                      F-12
<PAGE>   50



    USEC terminated AVLIS efforts with its contractors, implemented workforce
reductions and is conducting an orderly ramp-down of AVLIS activities at LLNL in
California. The suspension of AVLIS resulted in a special charge of $34.7
million in the year ended June 30, 1999, for contract terminations, shutdown
activities and employee severance and benefit arrangements. As all project
development costs have been expensed, there was no asset write-off. It is
expected that substantially all of the shutdown activities will be completed
within one year.

    Project development costs relating to AVLIS activities amounted to $133.7
million, $134.7 million, and $103.9 million for the years ended June 30, 1997,
1998 and 1999, respectively, and were charged to expense as incurred.

WORKFORCE REDUCTIONS AND PRIVATIZATION COSTS

    Special charges amounted to $46.6 million for the year ended June 30, 1998,
for costs related to the privatization and certain severance and transition
benefits to be paid to plant workers in connection with workforce reductions, as
follows (in millions):

</TABLE>

    Privatization costs of $13.8 million were paid in July 1998, worker and
community transition assistance benefits of $20.0 million were paid to DOE in
June 1998, and payments of $5.9 million for workers' pre-existing severance
benefits with respect to 312 workers had been made as of June 30, 1999.

8. ENVIRONMENTAL MATTERS

    Environmental compliance costs include the handling, treatment and disposal
of hazardous substances and wastes. Pursuant to the USEC Privatization Act
("Privatization Act"), environmental liabilities associated with plant
operations prior to July 28, 1998, are the responsibility of the U.S.
Government, except for liabilities relating to certain identified wastes
generated by USEC and stored at the plants. DOE remains responsible for
decontamination and decommissioning of the plants.

DEPLETED URANIUM

    USEC accrues estimated costs for the future disposition of depleted uranium,
based on estimates of transportation, conversion and disposal costs. Pursuant to
the Privatization Act, depleted uranium generated by USEC through the IPO Date
was transferred to DOE. Depleted uranium generated after the IPO Date is the
responsibility of USEC, except in June 1998, USEC paid $50.0 million to DOE and
DOE assumed responsibility for disposal of a certain amount of depleted uranium
generated by USEC from October 1998 to September 2005. Deferred costs resulting
from the payment amounted to $43.7 million at June 30, 1999, and are being
amortized as a charge against production costs using a straight line method over
the life of the agreement. USEC stores depleted uranium at the plants and
continues to evaluate various proposals for its disposition. The accrued
liability included in other long-term liabilities amounted to $24.8 million at
June 30, 1999.



                                      F-13
<PAGE>   51


OTHER ENVIRONMENTAL MATTERS

    USEC's operations generate hazardous, low-level radioactive and mixed
wastes. The storage, treatment, and disposal of wastes are regulated by federal
and state laws. USEC utilizes offsite treatment and disposal facilities and
stores wastes at the plants pursuant to permits, orders and agreements with DOE
and various state agencies.

    The accrued liability for the treatment and disposal of stored wastes
generated by USEC's operations included in other liabilities amounted to $8.3
million at June 30, 1998 and $7.1 million at June 30, 1999.

NUCLEAR INDEMNIFICATION

    USEC is indemnified by DOE under the Price-Anderson Act for third-party
liability claims arising from nuclear incidents with respect to activities at
the plants, including domestic transportation of uranium to and from the plants.

DOE SERVICES

    Services are provided to DOE by USEC for environmental restoration, waste
management and other activities based on actual costs incurred at the plants.
Reimbursements by DOE to USEC for actual costs incurred amounted to $53.4
million, $51.6 million and $38.3 million for the years ended June 30, 1997, 1998
and 1999, respectively.

9. COMMITMENTS AND CONTINGENCIES

POWER COMMITMENTS

    Under the terms of the plant lease, USEC purchases electric power at amounts
based on actual costs incurred under DOE's power contracts with OVEC and EEI
that extend through December 2005. USEC has the right to have DOE terminate the
power contracts with notice ranging from three to five years.

    Under the power contracts with DOE, USEC assumed responsibility for DOE's
guarantee of OVEC's senior secured notes with a remaining balance of $54.8
million at June 30, 1999, for expenditures related to compliance with the Clean
Air Act Amendments of 1990, including facilities for fuel switching and the
installation of continuous emission monitors.

    Subject to reductions resulting from the sale of power not taken, USEC is
obligated, whether or not it takes delivery of power, to make minimum annual
payments for demand charges, which reflect capital and operating costs, debt
service, taxes and a return on capital, estimated as follows (in millions):

<PAGE>   52


    Upon termination of the power contracts, USEC is responsible for and accrues
for its pro rata share of costs of future decommissioning and shutdown
activities at dedicated coal-fired power generating facilities owned and
operated by OVEC and EEI. The accrued cost included in other liabilities
amounted to $18.1 million at June 30, 1998 and 1999.

LEASE COMMITMENTS

    Total costs incurred under the plant lease with DOE and leases for office
space and equipment aggregated $23.2 million, $11.5 million, and $8.1 million
for the years ended June 30, 1997, 1998 and 1999, respectively. Minimum lease
payments are estimated at $5.0 million for each of the years ending June 30,
2000 to 2004.

    USEC has the right to extend the plant lease indefinitely at its sole option
and may terminate the lease in its entirety or with respect to one of the plants
at any time upon two years' notice. Upon termination of the lease, USEC is
responsible for certain lease turnover activities at the plants, including
documentation of the condition of the plants and termination of facility
operations. Lease turnover costs are accrued and charged to production costs
over the expected lease period, which is estimated to extend through calendar
year 2006, and the accrued cost included in other liabilities amounted to $23.2
million at June 30, 1998 and $28.7 million at June 30, 1999.

10. OPERATIONS AND MAINTENANCE CONTRACT

    Effective May 18, 1999, the operations and maintenance contract with
Lockheed Martin Utility Systems ("LMUS"), a subsidiary of Lockheed Martin
Corporation, was terminated by USEC. Most employees of LMUS became employees of
USEC. Under the contract, LMUS provided labor, services, and materials and
supplies to operate and maintain the plants. USEC funded LMUS for actual costs
incurred and contract fees. USEC has indemnified LMUS for certain liabilities
associated with performance of the operations and maintenance contract for the
term of the contract. In this regard, the Privatization Act generally provides
that liabilities attributable to plant operations prior to July 28, 1998, remain
liabilities of the U.S. Government.

    Under the contract, USEC was responsible for and accrued for its pro rata
share of pension and postretirement health and life insurance costs relating to
LMUS employee benefit plans. Costs for such benefits based on actuarial
estimates and matching contributions to a 401(k) defined contribution plan
amounted to $20.8 million, $22.4 million, and $21.5 million for the years ended
June 30, 1997, 1998 and 1999, respectively.

11. PENSION AND POSTRETIREMENT HEALTH AND LIFE BENEFITS

    Pursuant to the Privatization Act and in connection with the termination of
the LMUS contract and the transfer of LMUS employees to USEC effective May 18,
1999, pension and postretirement health and life benefit obligations and related
plan assets were transferred from plans sponsored by Lockheed Martin Corporation
to plans sponsored by USEC.

    There are 7,500 employees and retirees covered by defined benefit pension
plans providing retirement benefits based on compensation and years of service,
and 4,200 employees and their dependents covered by postretirement health and
life benefit plans. DOE retained the obligation for postretirement health and
life benefits for 2,400 workers who retired prior to the IPO Date.

    Plan assets are maintained in trusts and consist mainly of common stock and
fixed-income investments. The transfer of plan assets and benefit obligations is
subject to adjustment to reflect final actuarial valuations. The expected cost
of providing pension and postretirement health and life benefits, including the
amortization of actuarial gains and losses, is accrued over the years that
employees render services. Assumptions used in the calculation of the benefit
obligations follow:.

</TABLE>

    The health care cost trend rate used to measure the postretirement health
benefit obligation is 8% in fiscal 2000, and is assumed to decrease gradually to
5% by fiscal 2002 and remain at that level thereafter. An increase or decrease
of one percentage point in the assumed health care cost trend rate would result
in a change in the benefit obligation of 19% or $25.0 million.

(1)  Pursuant to the Privatization Act, in December 1996, USEC transferred to
     DOE the natural uranium component of low enriched uranium from highly
     enriched uranium purchased under the Russian Contract in calendar years
     1995 and 1996. As a result of the transfer, the purchase cost of $160.4
     million, including related shipping charges, was recorded as a return of
     capital.

(2)  Under the Privatization Act, in April 1998, DOE transferred to USEC 50
     metric tons of highly enriched uranium and 7,000 metric tons of natural
     uranium. USEC is responsible for costs related to the blending of the
     highly enriched uranium into low enriched uranium, as well as certain
     transportation, safeguards and security costs. As a result of the transfer,
     long-term uranium inventories and stockholders' equity were increased by
     $302.9 million based on DOE's historical costs for the uranium.

(3)  An exit dividend of $1,709.4 million was paid to the U.S. Government at the
     IPO Date. The amount of the exit dividend in excess of retained earnings
     was recorded as a reduction of excess of capital over par value.

(4)  Pursuant to the Privatization Act, depleted uranium generated by USEC
     through the IPO Date was transferred to DOE, and the accrued liability of
     $373.8 million for depleted uranium disposition was transferred to
     stockholders' equity.

    In February 1999, stockholders approved the USEC Inc. 1999 Equity Incentive
Plan, under which 9.0 million shares of common stock are reserved for issuance
over ten years, including incentive stock options, nonqualified stock options,
restricted stock or stock units, performance awards and other stock-based
awards. There were 318,000 shares of restricted stock granted during the year
ended June 30, 1999. Sale of these shares is restricted prior to the date of
vesting. Deferred compensation from restricted stock awards, based on the fair
market value at the date of grant, amounted to $4.4 million for the year ended
June 30, 1999. Deferred compensation is amortized to expense on a straight-line
basis over the vesting period.

    In February 1999, stockholders approved the USEC Inc. 1999 Employee Stock
Purchase Plan under which 2.5 million shares of common stock can be purchased
over ten years by eligible employees at 85% of the lower of the market price at
the beginning or the end of each six-month offer period. Employees can elect to
designate up to 10% of their compensation to purchase common stock under the
plan. Shares purchased are allocated to participants' accounts and, upon
request, shares are distributed. The initial six-month offer period began in
March 1999.

    Pursuant to the Privatization Act, certain limitations were established on
the ability of a person to acquire more than 10% of USEC's voting securities for
a three-year period after the IPO Date and certain foreign ownership limitations
were established.

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

(1)  Special charges of $34.7 million ($22.7 million or $.23 per share aftertax)
     are for contract terminations, shutdown activities, and employee severance
     and benefit arrangements related to the suspension of development of the
     AVLIS technology. Since all project development costs were charged to
     expense, there was no asset write-off.

(2)  Prior to the IPO Date, USEC had no debt.

(3)  USEC became subject to federal, state and local income taxes at the IPO
     date. The provision for income taxes includes a special income tax benefit
     of $54.5 million ($.54 per share) for deferred income tax benefits that
     arise from the transition to taxable status. Excluding the special tax
     benefit, the provision for income taxes was $51.6 million.

(4)  Special charges of $46.6 million are for costs related to the privatization
     and certain severance and transition benefits in connection with workforce
     reductions at the production plants.

              ISSUE, EXECUTION, FORM AND REGISTRATION OF SECURITIES

         SECTION 2.01. Authentication and Delivery of Securities. Upon the
execution and delivery of this Indenture, or from time to time thereafter,
Securities in an aggregate principal amount not in excess of the amount
specified in the form of Security hereinabove recited (except as otherwise
provided in Section 2.08) may be executed by the Company and delivered to the
Trustee for authentication, and the Trustee shall thereupon authenticate and
make available for delivery said Securities to or upon the written order of the
Company, signed by its Chairman of the Board of Directors, or any Vice Chairman
of the Board of Directors, or its President or any Vice President (whether or
not designated by a number or numbers or a word or words added before or after
the title "Vice President") without any further action by the Company.

         SECTION 2.02. Execution of Securities. The Securities shall be signed
on behalf of the Company by its Chairman of the Board of Directors or its
President or any Vice President (whether or not designated by a number or
numbers or a word or words added before or after the title "Vice President").
Such signature may be the manual or facsimile signatures of the present or any
future such officers.

         In case any officer of the Company who shall have signed any of the
Securities shall cease to be such officer before the Security so signed shall be
authenticated and delivered by the Trustee or disposed of by the Company, such
Security nevertheless may be authenticated and delivered or disposed of as
though the person who signed such Security had not ceased to be such officer of
the Company; and any Security may be signed on behalf of the Company by such
persons as, at the actual date of the execution of such Security, shall be the
proper officers of

                                       8
<PAGE>   14



the Company, although at the date of the execution and delivery of this
Indenture any such person was not such officer.

         SECTION 2.03. Certificate of Authentication. Only such Securities as
shall bear thereon a certificate of authentication substantially in the form
hereinabove recited, executed by the Trustee by manual signature of one of its
authorized signatories, shall be entitled to the benefits of this Indenture or
be valid or obligatory for any purpose. Such certificate by the Trustee upon any
Security executed by the Company shall be conclusive evidence, and the only
evidence, that the Security so authenticated has been duly authenticated and
delivered hereunder and that the Holder is entitled to the benefits of this
Indenture.

         SECTION 2.04. Form, Denomination and Date of Securities; Payments of
Interest. The Securities and the Trustee's certificates of authentication shall
be substantially in the form recited above. The Securities shall be issuable in
denominations provided for in the form of Security recited above. The Securities
shall be numbered, lettered, or otherwise distinguished in such manner or in
accordance with such plans as the officers of the Company executing the same may
determine with the approval of the Trustee.

         Any of the Securities may be issued with appropriate insertions,
omissions, substitutions and variations, and may have imprinted or otherwise
reproduced thereon such legend or legends, not inconsistent with the provisions
of this Indenture, as may be required to comply with any law or with any rules
or regulations pursuant thereto, including those required by Section 2.05, or
with the rules of any securities market in which the Securities are admitted to
trading, or to conform to general usage.

         Each Security shall be dated the date of its authentication, shall bear
interest from the applicable date and shall be payable on the dates specified on
the face of the form of Security recited above.

         The Securities shall be issued initially in the form of one or more
global Securities (a "GLOBAL SECURITY") deposited with the Trustee as custodian
for the Depositary.

         The person in whose name any Security is registered at the close of
business on any Regular Record Date with respect to any Interest Payment Date
shall be entitled to receive the interest, if any, payable on such Interest
Payment Date notwithstanding any transfer or exchange of such Security
subsequent to the Regular Record Date and prior to such Interest Payment Date,
except if and to the extent the Company shall default in the payment of the
interest due on such Interest Payment Date, in which case such defaulted
interest, plus (to the extent lawful) any interest payable on the defaulted
interest, shall be paid to the persons in whose names outstanding Securities are
registered at the close of business on a subsequent record date (which shall be
not less than five Business Days prior to the date of such

                                       9
<PAGE>   15



payment) established by notice given by mail by or on behalf of the Company to
the holders of Securities not less than 15 days preceding such subsequent record
date.

         SECTION 2.05.  Global Security Legends. Each Global Security shall bear
the following legends on the face thereof:

                  UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED
                  REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, TO THE COMPANY
                  OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
                  PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME
                  OF CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN
                  AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY OR
                  SUCH OTHER REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY OR
                  SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED
                  REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY
                  PAYMENT HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY
                  AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE
                  DEPOSITORY TRUST COMPANY), ANY TRANSFER, PLEDGE OR OTHER USE
                  HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL
                  SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
                  HEREIN.

                  TRANSFERS OF THIS GLOBAL SECURITY SHALL BE
                  LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO
                  NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF
                  OR SUCH SUCCESSOR'S NOMINEE.

         SECTION 2.06. Registration, Transfer and Exchange. The Securities are
issuable only in registered form. The Company will keep at each office or agency
to be maintained for the purpose as provided in Section 3.02 (the "REGISTRAR") a
register or registers (the "SECURITY REGISTER(S)") in which, subject to such
reasonable regulations as it may prescribe, it will register, and will register
the transfer of, Securities as in this Article provided. Such Security Register
shall be in written form in the English language or in any other form capable of
being converted into such form within a reasonable time. At all reasonable times
such Security Register or Security Registers shall be open for inspection by the
Trustee.

         Upon due presentation for registration of transfer of any Security at
each such office or agency, the Company shall execute and the Trustee shall
authenticate and make available for delivery in the name of the transferee or
transferees a new

                                       10
<PAGE>   16



Security or Securities in authorized denominations for a like aggregate
principal amount.

         A Holder may transfer a Security only by written application to the
Registrar stating the name of the proposed transferee and otherwise complying
with the terms of this Indenture. No such transfer shall be effected until, and
such transferee shall succeed to the rights of a Holder only upon, final
acceptance and registration of the transfer by the Registrar in the Security
Register. Prior to the registration of any transfer by a Holder as provided
herein, the Company, the Trustee, and any agent of the Company shall treat the
person in whose name the Security is registered as the owner thereof for all
purposes whether or not the Security shall be overdue, and neither the Company,
the Trustee, nor any such agent shall be affected by notice to the contrary.
Furthermore, any Holder of a Global Security shall, by acceptance of such Global
Security, agree that transfers of beneficial interests in such Global Security
may be effected only through a book entry system maintained by the Holder of
such Global Security (or its agent) and that ownership of a beneficial interest
in the Security shall be required to be reflected in a book entry. When
Securities are presented to the Registrar or a co-Registrar with a request to
register the transfer or to exchange them for an equal principal amount of
Securities of other authorized denominations, the Registrar shall register the
transfer or make the exchange as requested if the requirements for such
transactions set forth herein are met. To permit registrations of transfers and
exchanges, the Company shall execute and the Trustee shall authenticate
Securities at the Registrar's request.

         The Company may require payment of a sum sufficient to cover any tax or
other similar governmental charge that may be imposed in connection with any
exchange or registration of transfer of Securities (other than any such transfer
taxes or other similar governmental charge payable upon exchanges pursuant to
Section 2.10, 7.05 or 9.03). No service charge to any Holder shall be made for
any such transaction.

         The Company shall not be required to exchange or register a transfer of
(a) any Securities for a period of 15 days next preceding the first mailing of
notice of redemption of Securities to be redeemed, or (b) any Securities
selected, called or being called for redemption except, in the case of any
Security where public notice has been given that such Security is to be redeemed
in part, the portion thereof not so to be redeemed.

         All Securities issued upon any transfer or exchange of Securities shall
be valid obligations of the Company, evidencing the same debt, and entitled to
the same benefits under this Indenture, as the Securities surrendered upon such
transfer or exchange.

         SECTION 2.07.  Book-Entry Provisions for Global Securities.  (a) Each
Global Security shall (i) be registered in the name of the Depositary for such
Global

                                       11
<PAGE>   17



Securities or the nominee of such Depositary, (ii) be delivered to the Trustee
as custodian for such Depositary and (iii) bear legends as set forth in Section
2.05.

         Members of, or participants in, the Depositary ("AGENT MEMBERS") shall
have no rights under this Indenture with respect to any Global Security held on
their behalf by the Depositary, or the Trustee as its custodian, or under the
Global Security, and the Depositary may be treated by the Company, the Trustee
and any agent of the Company or the Trustee as the absolute owner of such Global
Security for all purposes whatsoever. Notwithstanding the foregoing, nothing
herein shall prevent the Company, the Trustee or any agent of the Company or the
Trustee, from giving effect to any written certification, proxy or other
authorization furnished by the Depositary or impair, as between the Depositary
and its Agent Members, the operation of customary practices governing the
exercise of the rights of a holder of any Security.

          (b) Transfers of a Global Security shall be limited to transfers of
such Global Security in whole, but not in part, to the Depositary, its
successors or their respective nominees. Interests of beneficial owners in a
Global Security may be transferred in accordance with the rules and procedures
of the Depositary. In addition, Certificated Securities shall be transferred to
all beneficial owners in exchange for their beneficial interests if (i) the
Depositary notifies the Company that it is unwilling or unable to continue as
Depositary for the Global Security or the Depository ceases to be a "clearing
agency" registered under the Exchange Act and a successor depositary is not
appointed by the Company within 90 days of such notice or (ii) an Event of
Default of which a Responsible Officer of the Trustee has actual notice has
occurred and is continuing and the Registrar has received a request from the
Depositary to issue such Certificated Securities.

          (c) In connection with the transfer of the entire Global Security to
beneficial owners pursuant to paragraph (b) of this Section, such Global
Security shall be deemed to be surrendered to the Trustee for cancellation, and
the Company shall execute, and the Trustee shall authenticate and deliver, to
each beneficial owner identified by the Depositary in exchange for its
beneficial interest in such Global Security an equal aggregate principal amount
of Certificated Securities of authorized denominations.

          (d) The registered holder of a Global Security may grant proxies and
otherwise authorize any person, including Agent Members and persons that may
hold interests through Agent Members, to take any action which a Holder is
entitled to take under this Indenture or the Securities.

         SECTION 2.08. Mutilated, Defaced, Destroyed, Lost and Stolen
Securities. In case any temporary or definitive Security shall become mutilated,
defaced or be apparently destroyed, lost or stolen, and in the absence of notice
to the Company that such Security has been acquired by a bona fide purchaser,
the Company in its

                                       12
<PAGE>   18



discretion may execute, and upon the written request of any officer of the
Company, the Trustee shall authenticate and make available for delivery, a new
Security, bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated or defaced Security, or in lieu of and
substitution for the Security so apparently destroyed, lost or stolen. In every
case the applicant for a substitute Security shall furnish to the Company and to
the Trustee and any agent of the Company or the Trustee such security or
indemnity as may be required by them to indemnify and defend and to save each of
them harmless and, in every case of destruction, loss or theft evidence to their
satisfaction of the apparent destruction, loss or theft of such Security and of
the ownership thereof.

         Upon the issuance of any substitute Security, the Company may require
the payment of a sum sufficient to cover any transfer tax or other similar
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.
In case any Security which has matured or is about to mature, or has been called
for redemption in full, shall become mutilated or defaced or be apparently
destroyed, lost or stolen, the Company in its discretion may, instead of issuing
a substitute Security, pay or authorize the payment of the same (without
surrender thereof except in the case of a mutilated or defaced Security), if the
applicant for such payment shall furnish to the Company and to the Trustee and
any agent of the Company or the Trustee such security or indemnity as any of
them may require to save each of them harmless from all risks, however remote,
and, in every case of apparent destruction, loss or theft, the applicant shall
also furnish to the Company and the Trustee and any agent of the Company or the
Trustee evidence to their satisfaction of the apparent destruction, loss or
theft of such Security and of the ownership thereof.

         Every substitute Security issued pursuant to the provisions of this
Section by virtue of the fact that any Security is apparently destroyed, lost or
stolen shall constitute an additional contractual obligation of the Company,
whether or not the apparently destroyed, lost or stolen Security shall be at any
time enforceable by anyone and shall be entitled to all the benefits of (but
shall be subject to all the limitations of rights set forth in) this Indenture
equally and proportionately with any and all other Securities duly authenticated
and delivered hereunder. All Securities shall be held and owned upon the express
condition that, to the extent permitted by law, the foregoing provisions are
exclusive with respect to the replacement or payment of mutilated, defaced, or
apparently destroyed, lost or stolen Securities and shall preclude any and all
other rights or remedies notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment of
negotiable instruments or other securities without their surrender.

         SECTION 2.09.  Cancellation of Securities.  All Securities surrendered
for payment, redemption, registration of transfer or exchange, if surrendered to
the Company or any agent of the Company or the Trustee, shall be delivered to
the Trustee for cancellation or, if surrendered to the Trustee, shall be
cancelled by it; and

                                       13
<PAGE>   19



no Securities shall be issued in lieu thereof except as expressly permitted by
any of the provisions of this Indenture. If the Company shall acquire any of the
Securities, such acquisition shall not operate as a redemption or satisfaction
of the indebtedness represented by such Securities unless and until the same are
delivered to the Trustee for cancellation. All cancelled Securities held by the
Trustee shall be disposed of by the Trustee in accordance with its customary
procedures (or destroyed) and certification of their disposal shall be delivered
to the Company unless the Company directs that cancelled Securities be returned
to it.

         SECTION 2.10. Temporary Securities. Pending the preparation of
definitive Securities, the Company may execute and, upon receipt of an order
from the Company, the Trustee shall authenticate and make available for delivery
temporary Securities (printed, lithographed, typewritten or otherwise
reproduced, in each case in form satisfactory to the Trustee). Temporary
Securities shall be issuable as registered Securities without coupons, of any
authorized denomination, and substantially in the form of the definitive
Securities but with such omissions, insertions and variations as may be
appropriate for temporary Securities, all as may be determined by the Company
with the concurrence of the Trustee. Temporary Securities may contain such
reference to any provisions of this Indenture as may be appropriate. Every
temporary Security shall be executed by the Company and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Securities. Without unreasonable delay the
Company shall execute and shall furnish definitive Securities and thereupon
temporary Securities may be surrendered in exchange therefor without charge at
each office or agency to be maintained by the Company for the purpose pursuant
to Section 3.02, and the Trustee shall authenticate and make available for
delivery in exchange for such temporary Securities a like aggregate principal
amount of definitive Securities of authorized denominations. Until so exchanged
the temporary Securities shall be entitled to the same benefits under this
Indenture as definitive Securities.

         SECTION 2.11. CUSIP and CINS Numbers. The Company in issuing the
Securities may use "CUSIP" and "CINS" numbers (if then generally in use), and
the Trustee shall use CUSIP numbers and CINS numbers, as the case may be, in
notices of redemption or exchange as a convenience to Holders; provided that any
such notice shall state that no representation is made as to the correctness of
such numbers either as printed on the Securities or as contained in any notice
of redemption or exchange and that reliance may be placed only on the other
identification numbers printed on the Securities, and any such redemption or
exchange shall not be affected by any defect or omission of such numbers . The
Company shall promptly notify the Trustee of any change in the CUSIP number or
CINS number, as the case may be.

                    COVENANTS OF THE COMPANY AND THE TRUSTEE.

         SECTION 3.01. Payment of Principal and Interest. The Company covenants
and agrees that it will duly and punctually pay or cause to be paid the
principal of, and interest on, each of the Securities at the place or places, at
the respective times and in the manner provided in the Securities. Each
installment of interest on the Securities may be paid by mailing checks for such
interest payable to or upon the written order of the holders of Securities
entitled thereto as they shall appear on the registry books of the Company, or
by wire transfer to such holders in immediately available funds, to such bank or
other entity in the continental United States as shall be designated by such
holders and shall have appropriate facilities for such purpose, or in accordance
with the standard operating procedures of the Depositary.

         SECTION 3.02. Offices for Payments, etc. So long as any of the
Securities remain outstanding, the Company will maintain in The Borough of
Manhattan, The City of New York, an office or agency (which may be a drop
facility): (a) where the Securities may be presented or surrendered for payment,
(b) where the Securities may be surrendered for registration of transfer and for
exchange as in this Indenture provided and (c) where notices and demands to or
upon the Company in respect of the Securities or of this Indenture may be
served. The Company will give to the Trustee prompt written notice of the
location of any such office or agency and of any change of location thereof. In
case the Company shall fail to maintain any such office or agency or shall fail
to give such notice of the location or of any change in the location thereof,
presentations and demands may be made and notices may be served at the Corporate
Trust Office, and the Company hereby appoints the Trustee as its agent to
receive all such presentations, surrenders, notices and demands.

         The Company may also from time to time designate one or more other
offices or agencies (in or outside The Borough of Manhattan and The City of New
York) where the Securities may be presented or surrendered for any or all such
purposes and may from time to time rescind any such designation; provided,
however, that no such designation or recission shall in any manner relieve the
Company of its obligation to maintain an office or agency in The Borough of
Manhattan or The City of New York for such purposes. The Company will give
prompt written notice to the Trustee of any such designation or recission and
any change in the location of any such other office or agency. The Company
hereby designates the Trustee c/o First Union National Bank, 40 Broad Street,
Fifth Floor, Suite 550, New York, New York 10004 as such drop facility in
compliance with this Section 3.02

         SECTION 3.03. Appointment to Fill a Vacancy in Office of Trustee. The
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
will appoint, in the manner provided in Section 5.10, a Trustee, so that there
shall at all times be a Trustee hereunder.

         SECTION 3.04. Paying Agents. Whenever the Company shall appoint a
paying agent other than the Trustee, it will cause such paying agent to execute
and deliver to the Trustee an instrument in which such agent shall agree with
the Trustee, subject to the provisions of this Section,

          (a) that it will comply with the provisions of the Trust Indenture Act
applicable to it as a paying agent,

          (b) that it will hold all sums received by it as such agent for the
payment of the principal of or interest on the Securities (whether such sums
have been paid to it by the Company or by any other obligor on the Securities)
in trust for the benefit of the holders of the Securities or of the Trustee,

          (c) that it will give the Trustee notice of any failure by the Company
(or by any other obligor on the Securities) to make any payment of the principal
of or interest on the Securities when the same shall be due and payable, and

          (d) that it will pay any such sums so held in trust by it to the
Trustee upon the Trustee's written request at any time during the continuance of
the failure referred to in clause (c) above.

         Upon payment over to the Trustee, the paying agent (if other than the
Company) shall have no further liability for the money delivered to the Trustee.

         Whenever the Company shall have one or more paying agents, the Company
will, no later than one Business Day prior to each due date of the principal of
or interest on the Securities, deposit with the paying agent in an account
established for the benefit of the Holders, a sum sufficient to pay such
principal or interest, and (unless such paying agent is the Trustee) the Company
will promptly notify the Trustee of any failure to take such action.

         If, before 1:00 p.m. one Business Day prior to payment date, funds have
been received by the Trustee for payment of debt service due the following day,
funds shall be invested in any money market fund substantially all of which is
invested in direct obligations of the United States of America or obligations of
which are unconditionally guaranteed by the United States of America. All
interest earnings will be paid to the Company.

         If the Company shall act as its own paying agent, it will, on or before
each due date of the principal of or interest on the Securities, set aside,
segregate and hold in trust for the benefit of the holders of the Securities a
sum sufficient to pay such principal or interest so becoming due. The Company
will promptly notify the Trustee of any failure to take such action.

                                       16
<PAGE>   22



         Anything in the prior two paragraphs to the contrary notwithstanding,
in connection with any payment of principal and interest, the Company will, for
so long as the Depository is a Holder of the Securities, deposit sums with the
paying agent sufficient to pay such amounts not later than the time required by
the Depository's rules and regulations as in effect at the time such payment is
due.

         Anything in this Section to the contrary notwithstanding, the Company
may at any time, for the purpose of obtaining a satisfaction and discharge of
this Indenture or for any other reason, pay or cause to be paid to the Trustee
all sums held in trust by the Company or any paying agent hereunder, as required
by this Section, such sums to be held by the Trustee upon the trusts herein
contained.

         Anything in this Section to the contrary notwithstanding, the agreement
to hold sums in trust as provided in this Section are subject to the provisions
of Sections 10.05 and 10.06.

         SECTION 3.05. Certificates to Trustee. (a) The Company will deliver to
the Trustee within 120 days after the end of each fiscal year of the Company a
certificate from the principal executive, financial or accounting officer of the
Company stating that such officer has conducted or supervised a review of the
activities of the Company and its Subsidiaries and the Company's and its
Subsidiaries' performance under the Indenture and that, to the best of such
officer's knowledge, based upon such review, the Company has fulfilled all
obligations thereunder or, if there has been a default in the fulfillment of any
such obligation (determined without regard to any period of grace or requirement
of notice provided in the Indenture), specifying each such default and the
nature and status thereof.

          (b) The Company will deliver to the Trustee, as soon as possible and
in any event within 10 days after the Company becomes aware of the occurrence of
an Event of Default or a Default, an Officers' Certificate setting forth the
details of such Event of Default or Default, and the action which the Company
proposes to take with respect thereto.

          (c) The Company will deliver to the Trustee within 120 days after the
end of each fiscal year of the Company a written statement by the Company's
independent public accountants stating (i) that their audit examination has
included a review of the terms of this Indenture and the Securities as they
relate to accounting matters, and (ii) whether, in connection with their audit
examination, any Default has come to their attention and, if such a Default has
come to their attention, specifying the nature and period of the existence
thereof.

         SECTION 3.06. Securityholders' Lists. The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to it
of the names and addresses of Holders and shall otherwise comply with Section
312(a) of the Trustee Indenture Act. If and so long as the Trustee shall not be
the Registrar, the

                                       17
<PAGE>   23



Company will furnish or cause to be furnished to the Trustee a list in such form
as the Trustee may reasonably require of the names and addresses of the holders
of the Securities pursuant to Section 312 of the Trust Indenture Act of 1939 (a)
semi-annually not more than 15 days after each Regular Record Date as of such
Regular Record Date, and (b) at such other times as the Trustee may request in
writing, within thirty days after receipt by the Company of any such request as
of a date not more than 15 days prior to the time such information is furnished.

         SECTION 3.07. Reports by the Trustee. (a) The Trustee shall transmit to
Holders such reports concerning the Trustee and its actions under this Indenture
as may be required pursuant to the Trust Indenture Act of 1939 at the times and
in the manner provided pursuant thereto. If required by Section 313(a) of the
Trust Indenture Act of 1939, the Trustee shall, within sixty days after each
April 15 following the date of this Indenture deliver to Holders a brief report,
dated as of such April 15, which complies with the provisions of such Section
313(a).

         (b) A copy of each such report shall, at the time of such transmission
to Holders, be filed by the Trustee with each stock exchange, if any, upon which
the Securities are listed, with the Commission and with the Company. The Company
will promptly notify the Trustee when the Securities are listed on any stock
exchange or of any delisting thereof.

         SECTION 3.08. Limitation on Liens. The Company shall not, and shall not
permit any of its Subsidiaries to, create, assume or incur any Lien on any
Principal Property to secure any Debt of the Company or any other Person (other
than the Securities) without effectively providing that the Securities shall be
secured equally and ratably with, or prior to, such Debt so long as such Debt
shall be secured. There is, however, excluded from the foregoing restriction the
following: (a) Permitted Liens; (b) any Lien on any (i) property or assets
created at the time of the acquisition of such property or assets by the Company
or any of its Subsidiaries, or within 180 days after such time, to secure all or
part of the purchase price for such property or assets or Debt incurred to
finance such purchase price, whether such Debt was incurred prior to, at the
time of, or within 180 days of, such acquisition; provided that, any such Lien
does not extend to any other property or assets of the Company or any of its
Subsidiaries, or (ii) property to secure all or part of the cost of the
development, construction, repair or improvement thereon or to secure Debt
incurred prior to, at the time of, or within 180 days after, the completion of
such development, construction, repair or improvement or the commencement of
full operations thereof (whichever is later) to provide funds for any such
purpose; provided that, any such Lien does not extend to any other property or
assets of the Company or any of its Subsidiaries; (c) (i) any Lien on any
property or assets existing thereon at the time of acquisition thereof by the
Company or any of its Subsidiaries (whether or not the obligations secured
thereby are assumed by the Company or any of its Subsidiaries), or (ii) the
assumption by the Company or any of its Subsidiaries of obligations secured by
any Lien existing at the time of acquisition by the Company or any of its

                                       18
<PAGE>   24



Subsidiaries of the property or assets subject to such Lien or at the time of
the acquisition of the Person which owns such property or assets, or (iii) any
Lien on any property or assets of a Person existing thereon at the time (1) such
Person becomes a Subsidiary of the Company, (2) such Person is merged into, or
consolidated with, the Company or any of its Subsidiaries or (3) of a sale,
lease or other disposition of the properties of a Person (or division thereof)
as an entirety or substantially as an entirety to the Company or any of its
Subsidiaries, provided that in each of the foregoing cases listed in this clause
(c), such Lien was not created as a result of or in connection with or in
anticipation of any such transaction and does not extend to any other property
or assets of the Company or any of its Subsidiaries; (d) any Lien on any
property or assets of the Company or any of its Subsidiaries in existence on the
date of the Indenture; (e) any Lien arising by reason of any attachment,
judgment, decree or order of any governmental or court authority, so long as any
proceeding initiated to review such attachment, judgment, decree or order shall
not have been terminated or the period within which such proceeding may be
initiated shall not expire, or such attachment, judgment, decree or order shall
otherwise be effectively stayed; and (f) any extension, renewal, refinancing,
refunding or replacement (or successive extensions, renewals, refinancings,
refundings or replacements) of any Lien, in whole or part, that is referred to
in clauses (a) through (e) (inclusive) above, or any Debt secured thereby.

         Notwithstanding the foregoing, under the Indenture, the Company may,
and may permit any of its Subsidiaries to, create, assume or incur any Lien upon
any Principal Property to secure any Debt of the Company or any Person (other
than the Securities) that is not excepted by clauses (a) through (f) (inclusive)
above without securing the Securities, provided that, after giving effect to the
creation, assumption or incurrence of such Lien and Debt, and the application of
proceeds of such Debt, if any, received by the Company or any of its
Subsidiaries as a result thereof, the aggregate principal amount of all Debt
then outstanding secured by such Lien and all similar Liens, together with all
net sale proceeds from Sale-Leaseback Transactions (excluding Sale-Leaseback
Transactions permitted by clauses (i) through (iii) (inclusive) of Section 3.09)
would not exceed 10% of Consolidated Net Tangible Assets.

         SECTION 3.09. Limitation on Sale-Leaseback Transactions. The Company
shall not, nor shall it permit any of its Subsidiaries to, engage in a
Sale-Leaseback Transaction, unless: (a) the Sale-Leaseback Transaction involves
a lease for a period, including renewals, of not more than three years; (b) the
Company or such Subsidiary would be entitled to incur Debt secured by a Lien on
Principal Property subject thereto in a principal amount equal to or exceeding
the net sale proceeds from such Sale-Leaseback Transaction without equally and
ratably securing the Securities pursuant to Section 3.08; or (c) the Company or
such Subsidiary, within a 180 day period after such Sale-Leaseback Transaction,
applies or causes to be applied an amount not less than the net sale proceeds
(which, in the case of a sale and transfer other than for cash, shall be an
amount equal to the fair market value of the Principal

                                       19
<PAGE>   25



Property so leased) from such Sale-Leaseback Transaction to (i) the prepayment,
repayment, reduction or retirement of any pari passu Debt of the Company or any
of its Subsidiaries, or (ii) the expenditure or expenditures for Principal
Property used or to be used in the ordinary course of business of the Company or
any of its Subsidiaries.

         SECTION 3.10. SEC Reports. (i) So long as any of the Securities remain
outstanding, whether or not the Company is then required to file with the
Commission information, documents or reports pursuant to Section 13 or Section
15(d) of the Exchange Act, the Company will file with the Trustee and the
Commission, in accordance with rules and regulations prescribed from time to
time by the Commission, such of the supplementary and periodic information,
documents and reports which would be required pursuant to such sections if the
Company were subject thereto. All obligors on the Securities will comply with
Section 314(a) of the Trust Indenture Act of 1939.

         (ii) The Company shall promptly mail copies of all such annual reports,
information, documents and other reports provided to the Trustee pursuant to
Section 3.10(i) hereof within 15 days of the delivery thereof with the Trustee
to the Holders at their addresses appearing in the register of Securities
maintained by the Registrar. The Company shall also make such information
available to securities analysts and prospective investors upon request.

        (iii) Delivery of such reports, information and documents to the Trustee
is for informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

         SECTION 3.11. Existence. Subject to Articles Three and Eight of this
Indenture, the Company will do or cause to be done all things necessary to
preserve and keep in full force and effect its existence and the existence of
each of its Subsidiaries in accordance with the respective organizational
documents of the Company and each such Subsidiary and the rights (whether
pursuant to charter, partnership certificate, agreement, statute or otherwise),
material licenses and franchises of the Company and each such Subsidiary,
provided that the Company shall not be required to preserve any such right,
license or franchise, or the existence of any Subsidiary, if the maintenance or
preservation thereof is no longer desirable in the conduct of the business of
the Company and its Subsidiaries taken as a whole.

         SECTION 3.12. Payment of Taxes and Other Claims. The Company will pay
or discharge and shall cause each of its Subsidiaries to pay or discharge, or
cause to be paid or discharged, before the same shall become delinquent (a) all
material taxes, assessments and governmental charges levied or imposed upon (i)
the Company or

                                       20
<PAGE>   26



any such Subsidiary, (ii) the income or profits of any such Subsidiary which is
a corporation or (iii) the property of the Company or any such Subsidiary and
(b) all material lawful claims for labor materials and supplies that, if unpaid,
might by law become a lien upon the property of the Company or any such
Subsidiary; provided that the Company shall not be required to pay or discharge,
or cause to be paid or discharged, any such tax, assessment, charge or claim the
amount, applicability or validity of which is being contested in good faith by
appropriate proceedings and for which adequate reserves have been established.

         SECTION 3.13. Maintenance of Properties and Insurance. The Company will
cause all properties used or useful in the conduct of its business or the
business of any of its Subsidiaries, to be maintained and kept in good
condition, repair and working order and supplied with all necessary equipment
and will cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in the judgment of the Company may
be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided that nothing in
this Section 3.13 shall prevent the Company or any such Subsidiary from
discontinuing the use, operation or maintenance of any of such properties or
disposing of any of them, if such discontinuance or disposal is, in the judgment
of the Company, desirable in the conduct of the business of the Company or such
Subsidiary.

         The Company will provide or cause to be provided, for itself and its
Subsidiaries, insurance (including appropriate self-insurance) against loss or
damage of the kinds customarily insured against by corporations similarly
situated and owning like properties, including, but not limited to, products
liability insurance and public liability insurance, with reputable insurers or
with the government of the United States of America, or an agency or
instrumentality thereof, in such amounts, with such deductibles and by such
methods as shall be customary for corporations similarly situated in the
industry in which the Company or such Subsidiary, as the case may be, is then
conducting business.

         SECTION 3.14. Waiver of Stay, Extension or Usury Laws. The Company
covenants (to the extent that it may lawfully do so) that it will not (i) at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any stay or extension law or any usury law or other law
that would prohibit or forgive the Company from paying all or any portion of the
principal of or interest on the Securities as contemplated herein, wherever
enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this Indenture and the Company will expressly
waive all benefit or advantage of any such law and (ii) hinder, delay or impede
the execution of any power granted to the Trustee under this Indenture and will
suffer and permit the execution of every such power as though no such law had
been enacted.

                                    ARTICLE 4
             REMEDIES OF THE TRUSTEE AND HOLDERS ON EVENT OF DEFAULT

         SECTION 4.01.  Events of Default.  Each of the following constitutes an
"EVENT OF DEFAULT":

          (a) default in the payment of principal of, or premium, if any, on any
2006 Note or 2009 Note, as the case may be, when the same becomes due and
payable at maturity, upon acceleration, redemption or otherwise;

          (b) default in the payment of interest on any 2006 Note or 2009 Note,
as the case may be, when the same becomes due and payable, and such default
continues for a period of 30 days;

          (c) the Company defaults in the performance of or breaches any other
covenant or agreement in the Indenture or under the 2006 Notes or 2009 Notes, as
the case may be, (other than (a), or (b) above) and such default or breach
continues for a period of 60 consecutive days after written notice by the
Trustee or the Holders of 25% or more in aggregate principal amount of the 2006
Notes or 2009 Notes, as the case may be;

          (d) default in the payment of the principal of, or interest on, any
note, bond, coupon or other instrument or agreement evidencing or pursuant to
which there is outstanding Debt of the Company or any of its Subsidiaries,
whether such Debt now exists or shall hereafter be created, having an aggregate
principal amount exceeding $35.0 million (or its equivalent in any other
currency or currencies), other than the Securities, when that Debt becomes due
and payable (whether at maturity, upon redemption or acceleration or otherwise),
if such default shall continue for more than the period of grace, if any,
applicable thereto and the time for payment of such amount has not been
expressly extended;

          (e) a court having jurisdiction in the premises enters a decree or
order for (A) relief in respect of the Company or any of its Subsidiaries in an
involuntary case under any applicable bankruptcy, insolvency or other similar
law now or hereafter in effect, (B) appointment of a receiver, liquidator,
assignee, custodian, trustee, sequestrator or similar official of the Company or
any of its Subsidiaries or for all or substantially all of the property and
assets of the Company or any of its Subsidiaries or (C) the winding up or
liquidation of the affairs of the Company or any of its Subsidiaries and, in
each case, such decree or order shall remain unstayed and in effect for a period
of 60 consecutive days; or

          (f) the Company or any of its Subsidiaries (A) commences a voluntary
case under any applicable bankruptcy, insolvency or other similar law now or
hereafter in effect, or consents to the entry of an order for relief in an
involuntary case under any

                                       22
<PAGE>   28



such law, (B) consents to the appointment of or taking possession by a receiver,
liquidator, assignee, custodian, trustee, sequestrator or similar official of
the Company or any of its Subsidiaries or for all or substantially all of the
property and assets of the Company or any of its Subsidiaries or (C) effects any
general assignment for the benefit of creditors.

         SECTION 4.02. Acceleration. If an Event of Default (other than an Event
of Default specified in clause (e) or (f) of Section 4.01 that occurs with
respect to the Company) occurs and is continuing under the Indenture, the
Trustee or the Holders of at least 25% in aggregate principal amount of the 2006
Notes or 2009 Notes, as the case may be, then outstanding, by written notice to
the Company (and to the Trustee if such notice is given by the Holders (the
"ACCELERATION NOTICE")), may, and the Trustee at the request of such Holders
shall, declare the principal of, premium, if any, and accrued interest on the
2006 Notes or 2009 Notes, as the case may be, to be immediately due and payable.
Upon a declaration of acceleration, such principal of, premium, if any, and
accrued interest shall be immediately due and payable. In the event of a
declaration of acceleration because an Event of Default set forth in clause (d)
of Section 4.01 has occurred and is continuing, such declaration of acceleration
shall be automatically rescinded and annulled if the event of default triggering
such Event of Default pursuant to clause (d) of Section 4.01 shall be remedied
or cured by the Company or the relevant Subsidiary or waived by the holders of
the relevant Debt within 60 days after the declaration of acceleration with
respect thereto. If an Event of Default specified in clause (e) or (f) Section
4.01 occurs with respect to the Company, the principal of, premium, if any, and
accrued interest on the Securities then outstanding shall ipso facto become and
be immediately due and payable without any declaration or other act on the part
of the Trustee or any Holder.

         SECTION 4.03. Other Remedies. If an Event of Default occurs and is
continuing, the Trustee may pursue any appropriate remedy to collect the payment
of principal or interest on the Securities or to enforce the performance of any
provision of the Securities or this Indenture.

         The Trustee may maintain a proceeding even if it does not possess any
of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Holder in exercising any right or remedy accruing
upon an Event of Default shall not impair the right or remedy or constitute a
waiver of or acquiescence in the Event of Default. All remedies are cumulative
to the extent permitted by law except as otherwise provided with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

         SECTION 4.04. Waiver of Past Defaults. The Holders of at least a
majority in principal amount of the outstanding 2006 Notes or 2009 Notes, as the
case may be, by written notice to the Company and to the Trustee, may waive all
past defaults and rescind and annul a declaration of acceleration and its
consequences if (i) all existing Events of Default, other than the nonpayment of
the principal of, premium, if any,

                                       23
<PAGE>   29



and interest on the 2006 Notes or 2009 Notes, as the case may be, that have
become due solely by such declaration of acceleration, have been cured or waived
and (ii) the rescission would not conflict with any judgment or decree of a
court of competent jurisdiction. 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.

         SECTION 4.05. Control by Majority. The Holders of at least a majority
in aggregate principal amount of the outstanding 2006 Notes or 2009 Notes, as
the case may be, may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee. However, the Trustee may refuse to follow any
direction that conflicts with law or the Indenture, that may involve the Trustee
in personal liability, or that the Trustee determines in good faith may be
unduly prejudicial to the rights of Holders of 2006 Notes or 2009 Notes, as the
case may be, not joining in the giving of such direction and may take any other
action it deems proper that is not inconsistent with any such direction received
from Holders of 2006 Notes or 2009 Notes, as the case may be.

         SECTION 4.06.  Limitation on Suits.  A Holder may not pursue any remedy
with respect to the Indenture or the 2006 Notes or 2009 Notes, as the case may
be, unless:

         (i) the Holder gives the Trustee written notice of a continuing Event
of Default with respect to the 2006 Notes or 2009 Notes, as the case may be;

         (ii) the Holders of at least 25% in aggregate principal amount of
outstanding 2006 Notes or 2009 Notes, as the case may be, make a written request
to the Trustee to pursue the remedy;

         (iii) such Holder or Holders offer the Trustee indemnity satisfactory
to the Trustee against any costs, liability or expense;

         (iv) the Trustee does not comply with the request within 60 days after
receipt of the request and the offer of indemnity; and

         (v) during such 60-day period, the Holders of at least a majority in
aggregate principal amount of the outstanding 2006 Notes or 2009 Notes, as the
case may be, do not give the Trustee a direction that is inconsistent with the
request; it being understood and intended that no one or more Holders shall have
any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb or prejudice the rights of any other
Holders or to obtain or to seek to obtain priority or preference over any other
Holders or to enforce any right under this

                                       24
<PAGE>   30



Indenture, except in the manner herein provided and for the equal and
proportionate benefit of all Holders.

         SECTION 4.07. Rights of Holders to Receive Payment. Notwithstanding any
other provision of this Indenture, the right of any Holder to receive payment of
principal, premium, if any, and interest on the Security, on or after the
respective due dates expressed in the Security, or to bring suit for the
enforcement of any such payment on or after such respective dates, shall not be
impaired or affected without the consent of the Holder.

         SECTION 4.08. Collection Suit by Trustee. If an Event of Default
specified in Section 4.01(a) or (b) hereof occurs and is continuing, the Trustee
is authorized to recover judgment in its own name and as trustee of an express
trust against the Company or any other obligor for the whole amount of
principal, premium, if any, and interest remaining unpaid on the Securities and
interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover amounts due the Trustee under
Section 5.07 hereof, including the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

         SECTION 4.09. Trustee May File Proofs of Claim. The Trustee is
authorized to file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee (including any
claim for the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel) and the Holders allowed in any judicial
proceedings relative to the Company (or any other obligor upon the Securities),
its creditors or its property and shall be entitled and empowered to collect,
receive and distribute any money or other property payable or deliverable on any
such claims and any custodian in any such judicial proceeding is hereby
authorized by each Holder to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, and any other amounts due the Trustee under Section 5.07 hereof. To
the extent that the payment of any such compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel, and any other amounts due
the Trustee under Section 5.07 hereof out of the estate in any such proceeding,
shall be denied for any reason, payment of the same shall be secured by a Lien
on, and shall be paid out of, any and all distributions, dividends, money,
securities and other properties which the Holders may be entitled to receive in
such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof, or to authorize
the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

         SECTION 4.10.  Priorities.  If the Trustee collects any money pursuant
to this Article, it shall pay out the money in the following order:

         First:  to the Trustee, its agents and attorneys for amounts due under
Section 5.07, including payment of all compensation, expense and liabilities
incurred, and all advances made, by the Trustee and the costs and expenses of
collection;

         Second:  to Holders for amounts due and unpaid on the Securities for
principal, premium, if any, and interest, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Securities
for principal, premium, if any and interest, respectively; and

         Third: to the Company or to such party as a court of competent
jurisdiction shall direct.

         The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 4.10 upon five Business Days prior notice to
the Company.

         SECTION 4.11. Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as a Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay
the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees and expenses, against any party
litigant in the suit, having due regard to the merits and good faith of the
claims or defenses made by the party litigant. This Section does not apply to a
suit by the Trustee, a suit by a Holder pursuant to Section 4.06 hereof, or a
suit by Holders of more than 10% in aggregate principal amount of the then
outstanding Securities.

                                    ARTICLE 5
                             CONCERNING THE TRUSTEE

         SECTION 5.01. Duties and Responsibilities of the Trustee; During
Default; Prior to Default. The Trustee, prior to the occurrence of a Default and
after the curing or waiving of any Default which may have occurred, undertakes
to perform such duties and only such duties as are specifically set forth in
this Indenture. In case an Event of Default has occurred (which has not been
cured or waived) 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 person would exercise under the circumstances in the
conduct of such person's own affairs.

                                       26
<PAGE>   32



         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 wilful misconduct, except that

          (a) prior to the occurrence of an Event of Default of which the
Trustee has actual notice and after the curing or waiving of all such Events of
Default which may have occurred:

                (i)  the duties and obligations of the Trustee shall be
         determined solely by the express provisions of this Indenture, and
         the Trustee shall not be liable except for the performance of such
         duties and obligations as are specifically set forth in this
         Indenture, and no implied covenants or obligations shall be read into
         this Indenture against the Trustee; and

                (ii) in the absence of bad faith on the part of the Trustee, the
         Trustee may conclusively rely, as to the truth of the statements and
         the correctness of the opinions expressed therein, upon any statements,
         certificates or opinions furnished to the Trustee and conforming to the
         requirements of this Indenture; but in the case of any such statements,
         certificates or opinions which by any provision hereof are specifically
         required to be furnished to the Trustee, the Trustee shall be under a
         duty to examine the same to determine whether or not they conform to
         the requirements of this Indenture (but need not confirm or investigate
         the accuracy of the facts stated therein);

          (b) the Trustee shall not be liable for any error of judgment made in
good faith by a Responsible Officer or Responsible Officers of the Trustee,
unless it shall be proved that the Trustee was negligent in ascertaining the
pertinent facts; and

          (c) the Trustee shall not be liable with respect to any action taken
or omitted by it (i) in good faith in accordance with the direction of the
holders of not less than a majority in principal amount of the Securities at the
time outstanding relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or (ii) in good faith and
believed by it to be authorized or within the discretion or rights or powers
conferred upon it by this Indenture.

         None of the provisions contained in this Indenture shall require the
Trustee to expend or risk its own funds or otherwise incur personal financial
liability in the performance of any of its duties or in the exercise of any of
its rights or powers, if there shall be reasonable ground for believing that the
repayment of such funds or adequate indemnity against such liability is not
reasonably assured to it.

         This Section 5.01 is in furtherance of and subject to Sections 315 and
316 of the Trust Indenture Act of 1939.

         SECTION 5.02. Certain Rights of the Trustee. In furtherance of and
subject to the Trust Indenture Act of 1939, and subject to Section 5.01:

          (a) the Trustee may conclusively rely and shall be protected in acting
or refraining from acting upon any resolution, Officers' Certificate or any
other certificate, statement, instrument, opinion, report, notice, request,
consent, order, bond, debenture, note, coupon, security or other paper or
document believed by it to be genuine and to have been signed or presented by
the proper party or parties;

          (b) any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an Officers' Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the secretary or an assistant secretary of the Company;

          (c) the Trustee may consult with counsel of its selection and any
advice or Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted to be taken by it
hereunder in good faith and in accordance with such advice or Opinion of
Counsel;

          (d) the Trustee shall be under no obligation to exercise any of the
trusts or powers vested in it by this Indenture at the request, order or
direction of any of the Securityholders pursuant to the provisions of this
Indenture, unless such Securityholders shall have offered to the Trustee
reasonable security or indemnity against the costs, expenses and liabilities
which might be incurred therein or thereby;

          (e) the Trustee shall not be liable for any action taken or omitted by
it in good faith and believed by it to be authorized or within the discretion,
rights or powers conferred upon it by this Indenture;

          (f) prior to the occurrence of a Default hereunder, of which the
Trustee has actual notice, and after the curing or waiving of all Defaults, the
Trustee shall not be bound to make any investigation into the facts or matters
stated in any resolution, certificate, statement, instrument, opinion, report,
notice, request, consent, order, approval, appraisal, bond, debenture, note,
coupon, security, or other paper or document unless requested in writing so to
do by the holders of not less than a majority in aggregate principal amount of
the Securities then outstanding, and, if the Trustee shall determine to make
such investigation, it shall be entitled to examine the books, records and
premises of the Company, personally or by agent or attorney; provided that, if
the payment within a reasonable time to the Trustee of the costs, expenses or
liabilities likely to be incurred by it in the making of such investigation is,
in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require
reasonable indemnity against such expenses or liabilities as a condition to
proceeding; the reasonable expenses of every such examination shall be paid by
the Company or, if

                                       28
<PAGE>   34



paid by the Trustee or any predecessor trustee, shall be repaid promptly by the
Company upon demand;

          (g) the Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or by or through agents or
attorneys not regularly in its employ and the Trustee shall not be responsible
for any misconduct or negligence on the part of any such agent or attorney
appointed with due care by it hereunder;

         (h) The Trustee shall not be deemed to have notice of any Default or
Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the Corporate Trust Office of the Trustee,
and such notice references the Securities and this Indenture; and

         (i) The Trustee shall have no duty to inquire as to the performance of
the Company's covenants herein.

         SECTION 5.03. Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof. The recitals contained herein and
in the Securities, except the Trustee's certificates of authentication, shall be
taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same. The Trustee makes no
representation as to the validity or sufficiency of this Indenture or of the
Securities. The Trustee shall not be accountable for the use or application by
the Company of any of the Securities or of the proceeds thereof.

         SECTION 5.04. Trustee and Agents May Hold Securities; Collections, etc.
The Trustee or any agent of the Company or the Trustee, in its individual or any
other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not the Trustee or such agent and may otherwise
deal with the Company and receive, collect, hold and retain collections from the
Company with the same rights it would have if it were not the Trustee or such
agent. However, subject to Section 5.13 hereof, the Trustee will comply with
Sections 310(b) and 311 of the Trust Indenture Act of 1939.

         SECTION 5.05. Moneys Held by Trustee. Subject to the provisions of
Section 10.06 hereof, all moneys received by the Trustee shall, until used or
applied as herein provided, be held in trust for the purposes for which they
were received, but need not be segregated from other funds except to the extent
required by mandatory provisions of law. Neither the Trustee nor any agent of
the Company or the Trustee shall be under any liability for interest on any
moneys received by it hereunder except as otherwise agreed with the Company.

                                       29
<PAGE>   35



         SECTION 5.06. Notice of Default. If any Default or any Event of Default
occurs and is continuing and if such Default or Event of Default is actually
known to a Responsible Officer of the Trustee, the Trustee shall mail to each
Holder in the manner and to the extent provided in Trust Indenture Act of 1939
Section 313(c) notice of the Default or Event of Default within 90 days after it
occurs, unless such Default or Event of Default has been cured; provided,
however, that, except in the case of a default in the payment of the principal
of, premium, if any, or interest on any Security, the Trustee shall be protected
in withholding such notice if and so long as the board of directors, the
executive committee or a trust committee of directors and/or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interest of the Holders.

         SECTION 5.07. Compensation and Indemnification of Trustee and Its Prior
Claim. The Company covenants and agrees to pay to the Trustee from time to time,
and the Trustee shall be entitled to, such compensation as shall be agreed in
writing between the Company and the Trustee (which shall not be limited by any
provision of law in regard to the compensation of a trustee of an express trust)
and the Company covenants and agrees to pay or reimburse the Trustee and each
predecessor Trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by or on behalf of it in accordance with any of
the provisions of this Indenture (including the reasonable compensation and the
expenses and disbursements of its counsel and of all agents and other persons
not regularly in its employ) except any such expense, disbursement or advance as
may arise from its negligence or bad faith. The Company also covenants to
indemnify the Trustee and each predecessor Trustee for, and to hold it harmless
against, any and all loss, liability, damage, claim or expense, including taxes
(other than taxes based on the income of the Trustee) incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this Indenture or the trusts hereunder and its
duties hereunder, including the costs and expenses of defending itself against
or investigating any claim of liability in the premises. The obligations of the
Company under this Section to compensate and indemnify the Trustee and each
predecessor Trustee and to pay or reimburse the Trustee and each predecessor
Trustee for expenses, disbursements and advances shall constitute additional
indebtedness hereunder and shall survive the satisfaction and discharge of this
Indenture. Such additional indebtedness shall be a senior lien to that of the
Securities upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the benefit of the holders of particular
Securities, and the Securities are hereby subordinated to such senior claim.

         When the Trustee incurs expenses or renders services in connection with
an Event of Default specified in Section 4.01(E) or Section 4.01(F), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

         SECTION 5.08. Right of Trustee to Rely on Officers' Certificate, etc.
Subject to Sections 5.01 and 5.02, whenever in the administration of the trusts
of this Indenture the Trustee shall deem it necessary or desirable that a matter
be proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officers' Certificate delivered to the Trustee, and such certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this Indenture upon the faith thereof.

         SECTION 5.09. Persons Eligible for Appointment as Trustee. The Trustee
hereunder shall at all times be a corporation having a combined capital and
surplus of at least $100,000,000, and which is eligible in accordance with the
provisions of Section 310(a) of the Trust Indenture Act of 1939. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of a Federal, State or District of Columbia supervising or
examining authority, then for the purposes 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 5.09, it shall resign immediately and in the manner
and with the effect hereinafter specified.

         SECTION 5.10. Resignation and Removal; Appointment of Successor
Trustee. (a) The Trustee may at any time resign by giving written notice of
resignation to the Company. Upon receiving such notice of resignation, the
Company shall promptly appoint a successor trustee by written instrument in
duplicate, executed by authority of the Board of Directors, one copy of which
instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee. If no successor trustee shall have been so appointed and have
accepted appointment within 30 days after the mailing of such notice of
resignation, the resigning trustee may petition, at the expense of the Company,
any court of competent jurisdiction for the appointment of a successor trustee,
or any Securityholder who has been a bona fide holder of a Security or
Securities for at least six months may, on behalf of himself and all others
similarly situated, petition any such court for the appointment of a successor
trustee. Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, appoint a successor trustee.

          (b) In case at any time any of the following shall occur:

               (i) the Trustee shall fail to comply with the provisions of
         Section 310(b) of the Trust Indenture Act of 1939, after written
         request therefor by the Company or by any Securityholder who has been a
         bona fide holder of a Security or Securities for at least six months;
         or


                                       31
<PAGE>   37



               (ii) the Trustee shall cease to be eligible in accordance with
         the provisions of Section 5.09 and shall fail to resign after written
         request therefor by the Company or by any such Securityholder; or

               (iii) the Trustee shall become incapable of acting, or shall be
         adjudged as bankrupt or insolvent, or a receiver or liquidator 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;

then, in any such case, the Company may remove the Trustee and appoint a
successor trustee by written instrument, in duplicate, executed by order of the
Board of Directors of the Company, one copy of which instrument shall be
delivered to the Trustee so removed and one copy to the successor trustee, or,
subject to Section 315(e) of the Trust Indenture Act of 1939, any Securityholder
who has been a bona fide holder of a Security or Securities 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. Such court may thereupon, after such notice,
if any, as it may deem proper and prescribe, remove the Trustee and appoint a
successor trustee.

          (c) The holders of a majority in aggregate principal amount of the
Securities at the time outstanding may at any time remove the Trustee and
appoint a successor trustee by delivering to the Trustee so removed, to the
successor trustee so appointed and to the Company the evidence provided for in
Section 6.01 of the action in that regard taken by the Securityholders.

         If no successor trustee shall have been so appointed and have accepted
appointment 30 days after the mailing of such notice of removal, the trustee
being removed may petition, at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor trustee. Such court
may thereupon, after such notice, if any, as it may deem proper and prescribe,
appoint a successor trustee.

          (d) Any resignation or removal of the Trustee and any appointment of a
successor trustee pursuant to any of the provisions of this Section 5.10 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 5.11.

         SECTION 5.11. Acceptance of Appointment by Successor Trustee. Any
successor trustee appointed as provided in Section 5.10 shall execute and
deliver to the Company and to its predecessor trustee an instrument accepting
such appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all rights,
powers, duties and obligations of its

                                       32
<PAGE>   38



predecessor hereunder, with like effect as if originally named as trustee
herein; but, nevertheless, on the written request of the Company or of the
successor trustee, upon payment of its charges then unpaid, the trustee ceasing
to act shall, subject to Section 10.06, pay over to the successor trustee all
moneys at the time held by it hereunder and shall execute and deliver an
instrument transferring to such successor trustee all such rights, powers,
duties and obligations. Upon request of any such successor trustee, the Company
shall execute any and all instruments in writing for more fully and certainly
vesting in and confirming to such successor trustee all such rights and powers.
Any trustee ceasing to act shall, nevertheless, retain a prior claim upon all
property or funds held or collected by such trustee to secure any amounts then
due it pursuant to the provisions of Section 5.07.

         Upon acceptance of appointment by a successor trustee as provided in
this Section 5.11, the Company shall mail notice thereof by first-class mail to
the holders of Securities at their last addresses as they shall appear in the
Security Register. If the acceptance of appointment is substantially
contemporaneous with the resignation, then the notice called for by the
preceding sentence may be combined with the notice called for by Section 5.10.
If the Company fails to mail such notice within 10 days after acceptance of
appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

         SECTION 5.12. Merger, Conversion, Consolidation or Succession to
Business of Trustee. Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or to which the Trustee's assets
may be sold, or any corporation resulting from any merger, conversion,
consolidation or sale to which the Trustee shall be a party or by which the
Trustee's property may be bound, or any corporation succeeding to all or
substantially all the corporate trust business of the Trustee, shall be the
successor of the Trustee hereunder, provided that such corporation shall be
eligible under the provisions of Section 5.09, without the execution or filing
of any paper or any further act on the part of any of the parties hereto,
anything herein to the contrary notwithstanding.

         In case at the time such successor to the Trustee shall succeed to the
trusts created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor Trustee and deliver such
Securities so authenticated; and, in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor Trustee; and in all such cases such certificate shall have the
full force which it is anywhere in the Securities or in this Indenture provided
that the certificate of the Trustee shall have; provided, that the right to
adopt the certificate of authentication of any predecessor Trustee or to
authenticate Securities in the name of any predecessor Trustee shall apply only
to its successor or successors by merger, conversion or consolidation.

<PAGE>   39



         SECTION 5.13. Preferential Collection of Claims. Reference is made to
Section 311 of the Trust Indenture Act of 1939. For purposes of Section 311(b)
(4) and (6) of such Act, the following terms shall mean:

          (a) "CASH TRANSACTION" means any transaction in which full payment for
goods or securities sold is made within seven days after delivery of the goods
or securities in currency or in checks or other orders drawn upon banks or
bankers and payable upon demand; and

          (b) "SELF-LIQUIDATING PAPER" means any draft, bill of exchange,
acceptance or obligation which is made, drawn, negotiated or incurred by the
Company for the purpose of financing the purchase, processing, manufacturing,
shipment, storage or sale of goods, wares or merchandise and which is secured by
documents evidencing title to, possession of, or a lien upon, the goods, wares
or merchandise or the receivables or proceeds arising from the sale of the
goods, wares or merchandise previously constituting the security, provided the
security is received by the Trustee simultaneously with the creation of the
creditor relationship with the Company arising from the making, drawing,
negotiating or incurring of the draft, bill of exchange, acceptance or
obligation.

                                    ARTICLE 6
                             CONCERNING THE HOLDERS

         SECTION 6.01. Evidence of Action Taken by Holders. Any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Securityholders may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Securityholders in person or by agent duly appointed in writing; and,
except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee.
Proof of execution of any instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and (subject to Sections
5.01 and 5.02) conclusive in favor of the Trustee and the Company, if made in
the manner provided in this Article.

         SECTION 6.02. Proof of Execution of Instruments and of Holding of
Securities; Record Date. Subject to Sections 5.01 and 5.02, the execution of any
instrument by a Securityholder or his agent or proxy may be proved in accordance
with such reasonable rules and regulations as may be prescribed by the Trustee
or in such manner as shall be satisfactory to the Trustee. The holding of
Securities shall be proved by the Security register or by a certificate of the
Registrar thereof. The Company may set a record date for purposes of determining
the identity of holders of Securities entitled to vote or consent to any action
referred to in Section 6.01,

                                       34
<PAGE>   40



which record date may be set at any time or from time to time by notice to the
Trustee, for any date or dates (in the case of any adjournment or
resolicitation) not more than 60 days nor less than five days prior to the
proposed date of such vote or consent, and thereafter, notwithstanding any other
provisions hereof, only holders of Securities of record on such record date
shall be entitled to so vote or give such consent or to withdraw such vote or
consent.

         SECTION 6.03. Securities Owned by Company Deemed Not Outstanding. In
determining whether the holders of the requisite aggregate principal amount of
Securities have concurred in any direction, consent or waiver under this
Indenture, Securities which are owned by the Company or any other obligor on the
Securities or by any person directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company or any other obligor
on the Securities shall be disregarded and deemed not to be outstanding for the
purpose of any such determination, except that for the purpose of determining
whether the Trustee shall be protected in relying on any such direction, consent
or waiver only Securities which a Responsible Officer of the Trustee actually
knows are so owned shall be so disregarded. Securities so owned which have been
pledged in good faith may be regarded as outstanding if the pledgee establishes
to the satisfaction of the Trustee the pledgee's right so to act with respect to
such Securities and that the pledgee is not the Company or any other obligor
upon the Securities or any person directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company or any
other obligor on the Securities. In case of a dispute as to such right, the
advice of counsel shall be full protection in respect of any decision made by
the Trustee in accordance with such advice. Upon request of the Trustee, the
Company shall furnish to the Trustee promptly an Officers' Certificate listing
and identifying all Securities, if any, known by the Company to be owned or held
by or for the account of any of the above-described persons; and, subject to
Sections 5.01 and 5.02, the Trustee shall be entitled to accept such Officers'
Certificate as conclusive evidence of the facts therein set forth and of the
fact that all Securities not listed therein are outstanding for the purpose of
any such determination.

         SECTION 6.04. Right of Revocation of Action Taken. At any time prior to
(but not after) the evidencing to the Trustee, as provided in Section 6.01, of
the taking of any action by the holders of the percentage in aggregate principal
amount of the Securities specified in this Indenture in connection with such
action, any holder of a Security the serial number of which is shown by the
evidence to be included among the serial numbers of the Securities the Holders
of which have consented to such action may, by filing written notice at the
Corporate Trust Office and upon proof of holding as provided in this Article,
revoke such action so far as concerns such Security. Except as aforesaid any
such action taken by the holder of any Security shall be conclusive and binding
upon such holder and upon all future holders and owners of such Security and of
any Securities issued in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon any such Security.
Any action taken by the holders of the percentage in

                                       35

aggregate principal amount of the Securities specified in this Indenture in
connection with such action shall be conclusively binding upon the Company, the
Trustee and the holders of all the Securities.

                                    ARTICLE 7
                             SUPPLEMENTAL INDENTURES

         SECTION 7.01.  Supplemental Indentures Without Consent of Holders.  The
Company and the Trustee may amend or supplement this Indenture or the Securities
without the consent of any Holder:

               (i) to cure any ambiguity, defect or inconsistency;

               (ii) to provide for uncertificated Securities in addition to or
         in place of certificated Securities;

               (iii) to provide for the assumption of the Company's obligations
         to the Holders of the Securities in the case of a merger, consolidation
         or sale of assets pursuant to Article Eight hereof;

               (iv) to make any change that would provide any additional rights
         or benefits to the Holders of the Securities or that does not adversely
         affect the legal rights hereunder of any such Holder; or

               (v) to comply with requirements of the Commission in order to
         effect or maintain the qualification of this Indenture under the Trust
         Indenture Act of 1939.

         Upon the request of the Company accompanied by a Board Resolution
authorizing the execution of any such supplemental indenture, and upon receipt
by the Trustee of the documents described in Section 7.04 hereof, the Trustee
shall join with the Company in the execution of any supplemental indenture
authorized or permitted by the terms of this Indenture and to make any further
appropriate agree ments and stipulations which may be therein contained, but the
Trustee shall not be obligated to enter into such supplemental indenture which
affects its own rights, duties or immunities under this Indenture or otherwise.

         SECTION 7.02. With Consent of Holders. Except as provided in the next
succeeding paragraphs, this Indenture or the 2006 Notes or 2009 Notes, as the
case may be, may be amended or supplemented with the consent of the Holders of
at least a majority in aggregate principal amount of the 2006 Notes or 2009
Notes, as the case may be, then outstanding (including consents obtained in
connection with a tender

                                       36
<PAGE>   42



offer or exchange offer for such 2006 Notes or 2009 Notes, as the case may
be,), and any existing default or compliance with any provision of this
Indenture or the 2006 Notes or 2009 Notes, as the case may be, may be waived
with the consent of the Holders of a majority in aggregate principal amount of
the then outstanding 2006 Notes or 2009 Notes, as the case may be, (including
consents obtained in connection with a tender offer or exchange offer for such
2006 Notes or 2009 Notes, as the case may be).

         Upon the request of the Company accompanied by a Board Resolution
authorizing the execution of any such supplemental indenture, and upon the
filing with the Trustee of evidence satisfactory to the Trustee of the consent
of the Holders as aforesaid, and upon receipt by the Trustee of the documents
described in Section 7.04 hereof, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such supplemental indenture.

         It shall not be necessary for the consent of the Holders under this
Section 7.02 to approve the particular form of any proposed amendment or waiver,
but it shall be sufficient if such consent approves the substance thereof.

         After an amendment, supplement or waiver under this Section becomes
effective, the Company shall mail to the Holders affected thereby a notice
briefly describing the amendment, supplement or waiver. Any failure of the
Company to mail such notice, or any defect therein, shall not, however, in any
way impair or affect the validity of any such supplemental indenture or waiver.
Subject to Sections 4.04 and 4.07 hereof, the Holders of a majority in aggregate
principal amount of the 2006 Notes or 2009 Notes, as the case may be, then
outstanding may waive compliance in a particular instance by the Company with
any provision of this Indenture or the 2006 Notes or 2009 Notes, as the case may
be. Without the consent of each Holder affected, however, an amendment or waiver
may not (with respect to any Security held by a non-consenting Holder):

         (i)   change the Stated Maturity of the principal of, or any
installment of interest on, any Security;

         (ii)  reduce the principal amount of, or premium, if any, or interest
on, any Security;

         (iii) reduce any amount payable on redemption of the Securities or upon
the occurrence on an Event of Default;

         (iv)  change the place or currency of payment of principal of, premium,
if any, or interest on, any Security;

                                       37
<PAGE>   43




         (v)    impair the right to institute suit for the enforcement of any
payment on or after the Stated Maturity (or, in the case of a redemption, on or
after the redemption date) of any Security;

         (vi)   reduce the above-stated percentage of outstanding Securities the
consent of whose Holders is necessary to modify or amend the Indenture;

         (vii)  waive a default in the payment of principal of, premium, if any,
or interest on the Securities;

         (viii) reduce the percentage or aggregate principal amount of
outstanding Securities the consent of whose Holders is necessary for waiver of
compliance with certain provisions of the Indenture or for waiver of certain
defaults; or

         (ix) modify or change any provision of the Indenture with respect to
modification and waiver.

         Neither the Company nor any of its Subsidiaries will, directly or
indirectly, pay or cause to be paid any consideration, whether by way of
interest, fee or otherwise to any Holder of any notes for or as an inducement to
any consent, waiver or amendment of any of the terms or provisions of the
Indenture or the Securities unless such consideration is offered to be paid or
agreed to be paid to all Holders of the Securities that consent, waive or agree
to amend in the time frame set forth in the solicitation documents relating to
such consent, waiver or agreement.

         SECTION 7.03. Effect of Supplemental Indenture. Upon the execution of
any supplemental indenture pursuant to the provisions hereof, this Indenture
shall be and be deemed to be modified and amended in accordance therewith and
the respective rights, limitations of rights, obligations, duties and immunities
under this Indenture of the Trustee, the Company and the holders of Securities
shall thereafter be determined, exercised and enforced hereunder subject in all
respects to such modifications and amendments, and all the terms and conditions
of any such supplemental indenture shall be and be deemed to be part of the
terms and conditions of this Indenture for any and all purposes.

         SECTION 7.04. Documents to Be Given to Trustee; Compliance with TIA.
The Trustee, subject to the provisions of Sections 5.01 and 5.02, may receive an
Officers' Certificate and an Opinion of Counsel as conclusive evidence that any
such supplemental indenture complies with the applicable provisions of this
Indenture. Every such supplemental indenture shall comply with the TIA.

         SECTION 7.05. Notation on Securities in Respect of Supplemental
Indentures. Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to the provisions of this Article may bear a
notation approved by

                                       38
<PAGE>   44



the Trustee as to form (but not as to substance) as to any matter provided for
by such supplemental indenture or as to any action taken at any such meeting. If
the Company or the Trustee shall so determine, new Securities so modified as to
conform, in the opinion of the Trustee and the Board of Directors, to any
modification of this Indenture contained in any such supplemental indenture may
be prepared by the Company, authenticated by the Trustee and delivered in
exchange for the Securities then outstanding.

                                    ARTICLE 8
                     CONSOLIDATION, MERGER OR SALE OF ASSETS

         SECTION 8.01. Consolidation, Merger or Sale of Assets. The Company
shall not consolidate with, merge with or into, or sell, convey, transfer, lease
or otherwise dispose of all or substantially all of its property and assets (as
an entirety or substantially an entirety in one transaction or a series of
related transactions) to, any Person nor permit any Person to merge with or into
the Company unless:

               (i)  the Company shall be the continuing Person, or the Person
         (if other than the Company) formed by such consolidation or into which
         the Company is merged or that acquired or leased such property and
         assets of the Company shall be a corporation organized and validly
         existing under the laws of the United States of America or any
         jurisdiction thereof and shall expressly assume, by a supplemental
         indenture, executed and delivered to the Trustee, all of the
         obligations of the Company on all of the Securities and under the
         Indenture;

               (ii)  immediately after giving effect to such transaction, no
         Default or Event of Default shall have occurred and be continuing;

               (iii) the Company delivers to the Trustee an Officers'
         Certificate and Opinion of Counsel, in each case stating that such
         consolidation, merger or transfer and such supplemental indenture
         complies with this provision and that all conditions precedent provided
         for herein relating to such transaction have been complied with.

         SECTION 8.02. Successor Corporation Substituted. (a) Upon any
consolidation or merger, or any sale, assignment, transfer, lease, conveyance or
other disposition of all or substantially all of the assets of the Company in
accordance with Section 8.01 hereof, the successor corporation formed by such
consolidation or into or with which the Company is merged or to which such sale,
assignment, transfer, lease, conveyance or other disposition is made shall
succeed to, and be substituted for (so that from and after the date of such
consolidation, merger, sale, assignment,

                                       39
<PAGE>   45



transfer, lease, conveyance or other disposition, the provisions of this
Indenture referring to the "Company" shall refer instead to the successor
corporation), and may exercise every right and power of, the Company under this
Indenture with the same effect as if such successor Person had been named as the
Company herein.

          (b) Notwithstanding the foregoing, (i) a consolidation or merger by
the Company with or into, or (ii) the sale, assignment, transfer, lease,
conveyance or other disposition by the Company of all or substantially all of
its property or assets to, one or more of its Subsidiaries shall not relieve the
Company from its obligations under this Indenture and the Securities.

         SECTION 8.03. Opinion of Counsel to Trustee. The Trustee, subject to
the provisions of Sections 5.01 and 5.02, may receive an Opinion of Counsel as
conclusive evidence that any such consolidation, merger, conveyance, sale,
transfer, lease, exchange or other disposition complies with the applicable
provisions of this Indenture.

                                    ARTICLE 9
                            REDEMPTION OF SECURITIES

         SECTION 9.01. Right of Optional Redemption; Prices. The Company at its
option may, at any time, redeem in whole or in part, in principal amounts of
$1,000 or any integral multiple thereof, the Securities upon payment of a
redemption price equal to the sum of (i) an amount equal to 100% of the
principal amount thereof and (ii) the Make-Whole Premium, together with accrued
and unpaid interest up to but not including the Redemption Date.

         SECTION 9.02. Notice of Redemption; Partial Redemptions. Notice of
redemption to the holders of Securities to be redeemed as a whole or in part
shall be given by mailing notice of such redemption by first class mail, postage
prepaid, at least 30 days and not more than 60 days prior to the date fixed for
redemption to such holders of Securities at their last addresses as they shall
appear upon the registry books. Any notice which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the Holder receives the notice. Failure to give notice by mail, or any defect in
the notice to the holder of any Security designated for redemption as a whole or
in part shall not affect the validity of the proceedings for the redemption of
any other Security.

         The notice of redemption to each such Holder shall identify the
Securities to be redeemed (including CUSIP or CINS numbers) and shall specify
the principal amount of each Security held by such Holder to be redeemed, the
date fixed for redemption, the redemption price, the place or places of payment,
that payment will

                                       40
<PAGE>   46



be made upon presentation and surrender of such Securities, that interest
accrued to the date fixed for redemption will be paid as specified in said
notice and that on and after said date interest thereon or on the portions
thereof to be redeemed will cease to accrue. In case any Security is to be
redeemed in part only the notice of redemption shall state the portion of the
principal amount thereof to be redeemed and shall state that on and after the
date fixed for redemption, upon surrender of such Security, a new Security or
Securities in principal amount equal to the unredeemed portion thereof will be
issued.

         The notice of redemption of Securities to be redeemed at the option of
the Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company.

         No later than 10:00 a.m. on the redemption date specified in the notice
of redemption given as provided in this Section, the Company will deposit with
the Trustee or with one or more paying agents (or, if the Company is acting as
its own paying agent, set aside, segregate and hold in trust as provided in
Section 3.04) an amount of money sufficient to redeem on the redemption date all
the Securities so called for redemption at the appropriate redemption price,
together with accrued interest to the date fixed for redemption. The Company
will deliver to the Trustee at least 70 days prior to the date fixed for
redemption an Officers' Certificate stating the aggregate principal amount of
Securities to be redeemed.

         If less than all of the Securities are to be redeemed at any time, the
Trustee shall select, either pro rata, by lot or by any other method it shall in
its sole discretion deem fair and appropriate, Securities to be redeemed in
whole or in part; provided that no Security of $1,000 in principal amount or
less shall be redeemed in part. The Trustee shall promptly notify the Company in
writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to be
redeemed. For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

         SECTION 9.03. Payment of Securities Called for Redemption. If notice of
redemption has been given as above provided, the Securities or portions of
Securities specified in such notice shall become due and payable on the date and
at the place stated in such notice at the applicable redemption price, together
with interest accrued to the date fixed for redemption, and on and after said
date (unless the Company shall default in the payment of such Securities at the
redemption price, together with interest accrued to said date) interest on the
Securities or portions of Securities so called for redemption shall cease to
accrue and, except as provided in Sections 5.05 and 11.06, such Securities shall
cease from and after the date fixed for redemption to be entitled to any benefit
or security under this Indenture, and the Holders thereof

                                       41
<PAGE>   47



shall have no right in respect of such Securities except the right to receive
the redemption price thereof and unpaid interest to the date fixed for
redemption. On presentation and surrender of such Securities at a place of
payment specified in said notice, said Securities or the specified portions
thereof shall be paid and redeemed by the Company at the applicable redemption
price, together with interest accrued thereon to the date fixed for redemption;
provided that any semi-annual payment of interest becoming due on or prior to
the date fixed for redemption shall be payable to the holders of such Securities
registered as such on the relevant Regular Record Date subject to the terms and
provisions of Section 2.04 hereof.

         If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate borne
by the Security.

         Upon presentation of any Security redeemed in part only, the Company
shall execute and the Trustee shall authenticate and make available for delivery
to or on the order of the Holder thereof, at the expense of the Company, a new
Security or Securities, of authorized denominations, in principal amount equal
to the unredeemed portion of the Security so presented.

         SECTION 9.04. Exclusion of Certain Securities from Eligibility for
Selection for Redemption. Securities shall be excluded from eligibility for
selection for redemption if they are identified by registration and certificate
number in a written statement signed by an authorized officer of the Company and
delivered to the Trustee at least 40 days prior to the last date on which notice
of redemption may be given as being owned of record and beneficially by, and not
pledged or hypothecated by either (a) the Company or (b) an entity specifically
identified in such written statement as directly or indirectly controlling or
controlled by or under direct or indirect common control with the Company.

                                   ARTICLE 10
                       DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 10.01. Company's Option to Effect Defeasance or Covenant
Defeasance. The Company may at its option by a Board Resolution, at any time,
elect to have either Section 10.02 or Section 10.03 applied to the outstanding
2006 Notes or 2009 Notes, as the case may be, upon compliance with the
conditions set forth below in this Article Ten.

         SECTION 10.02.  Legal Defeasance and Discharge. Upon the Company's
exercise under Section 10.01 hereof of the option applicable to this
Section 10.02, the Company shall be deemed to have been discharged from any and
all Obligations

                                       42
<PAGE>   48



with respect to all outstanding 2006 Notes or 2009 Notes, as the case may be, on
the date which is the 123rd day after the deposit referred to in Section
10.04(a); provided that all of the conditions set forth below are satisfied
(hereinafter, "LEGAL DEFEASANCE"). For this purpose, such Legal Defeasance means
that the Company shall be deemed to have paid and discharged the entire Debt
represented by the outstanding 2006 Notes or 2009 Notes, as the case may be,
which shall thereafter be deemed to be "outstanding" only for the purposes of
Section 10.05 hereof and the other Sections of this Indenture referred to in
clauses (i) and (ii) of this Section 10.02, and to have satisfied all its other
obligations under such 2006 Notes or 2009 Notes, as the case may be, and this
Indenture (and the Trustee, on demand of and at the expense of the Company,
shall execute proper instruments acknowledging the same), except for the
following provisions which shall survive until otherwise terminated or
discharged hereunder: (i) the rights of Holders of outstanding 2006 Notes or
2009 Notes, as the case may be, to receive solely from the trust fund described
in Section 10.04 hereof, and as more fully set forth in such Section, payments
in respect of the principal of, premium, if any, and interest on such 2006 Notes
or 2009 Notes, as the case may be, when such payments are due, (ii) the
Company's obligations with respect to such 2006 Notes or 2009 Notes, as the case
may be, under Sections 2.01, 2.02, 2.05, 2.06, 2.07, 2.08, 2.10, 3.01, 3.02,
3.04 and 10.05 hereof, (iii) the rights, powers, trusts, duties and immunities
of the Trustee hereunder, including, without limitation, the Trustee's rights
under Section 5.07 hereof, and the Company's obligations in connection therewith
and with this Article Ten. Subject to compliance with this Article Ten, the
Company may exercise its option under this Section 10.02 notwithstanding the
prior exercise of its option under Section 10.03 hereof with respect to the 2006
Notes or 2009 Notes, as the case may be.

         SECTION 10.03. Covenant Defeasance. Upon the Company's exercise under
Section 10.01 hereof of the option applicable to this Section 10.03, the Company
shall be released from its obligations under the covenants contained in Sections
3.08, 3.09, 3.10, clauses (c) and (d) of Article 4 and Article 8 hereof with
respect to the outstanding 2006 Notes or 2009 Notes, as the case may be, on and
after the date the conditions set forth below are satisfied (hereinafter,
"COVENANT DEFEASANCE"), and the 2006 Notes or 2009 Notes, as the case may be,
shall thereafter be deemed not outstanding for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
outstanding for all other purposes hereunder. For this purpose, such Covenant
Defeasance means that, with respect to the outstanding 2006 Notes or 2009 Notes,
as the case may be, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
covenant, whether directly or indirectly, by reason of any reference elsewhere
herein to any such covenant or by reason of any reference in any such covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a Default or an Event of Default under Section
4.01(c)

                                       43
<PAGE>   49



or (d) hereof, but, except as specified above, the remainder of this Indenture
and such 2006 Notes or 2009 Notes, as the case may be, shall be unaffected
thereby.

         If subsequent to the completion of a defeasance of certain covenants as
described in the immediately preceding paragraph, such outstanding 2006 Notes or
2009 Notes, as the case may be, are declared due and payable because of the
occurrence of any remaining Event of Default and the amount of money and U.S.
Government Obligations deposited in trust, as described below, would be
sufficient to pay amounts due on such 2006 Notes or 2009 Notes, as the case may
be, at Stated Maturity but may not be sufficient to pay amounts due on such 2006
Notes or 2009 Notes, as the case may be, upon any acceleration resulting from
such Event of Default, then the Company would remain liable for such payments.

         SECTION 10.04. Conditions to Legal or Covenant Defeasance. The
following shall be the conditions to application of either Section 10.02 or
Section 10.03 hereof to the outstanding 2006 Notes or 2009 Notes, as the case
may be:

          (a) the Company has deposited with the Trustee, in trust, money and/or
U.S. Government Obligations that through the payment of interest and principal
in respect thereof in accordance with their terms will provide money in an
amount sufficient, in the opinion of a nationally recognized firm of independent
public accountants expressed in a written certification thereof delivered to the
Trustee, to pay the principal of, premium, if any, and accrued interest on the
2006 Notes or 2009 Notes, as the case may be, on the Stated Maturity of such
payments in accordance with the terms of the Indenture and the 2006 Notes or
2009 Notes, as the case may be;

          (b) in the case of an election under Section 10.02 hereof, the Company
has delivered to the Trustee (i) either (x) an Opinion of Counsel to the effect
that Holders will not recognize income, gain or loss for Federal income tax
purposes as a result of the Company's exercise of its option under this Article
Ten and will be subject to Federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such deposit,
defeasance and discharge had not occurred, which Opinion of Counsel must be
based upon (and accompanied by a copy of) a ruling of the Internal Revenue
Service to the same effect unless there has been a change in applicable Federal
income tax law after the date of the Indenture such that a ruling is no longer
required or (y) a ruling directed to the Trustee received from the Internal
Revenue Service to the same effect as the aforementioned Opinion of Counsel and
(ii) an Opinion of Counsel to the effect that the creation of the defeasance
trust does not violate the Investment Company Act of 1940 and after the passage
of 123 days following the deposit, the trust fund will not be subject to the
effect of Section 547 of the United States Bankruptcy Code or Section 15 of the
New York Debtor and Creditor Law;

                                       44
<PAGE>   50



          (c) in the case of an election under Section 10.03 hereof, the
delivery by the Company to the Trustee of (i) an Opinion of Counsel to the
effect that, among other things, the Holders will not recognize income, gain or
loss for Federal income tax purposes as a result of such deposit and defeasance
and will be subject to Federal income tax on the same amount and in the same
manner and at the same times as would have been the case if such deposit and
defeasance had not occurred and (ii) an Opinion of Counsel to the effect that
the creation of the defeasance trust does not violate the Investment Company Act
of 1940 and after the passage of 123 days following the deposit, the trust fund
will not be subject to the effect of Section 547 of the United States Bankruptcy
Code or Section 15 of the New York Debtor and Creditor Law;

          (d) immediately after giving effect to such deposit on a pro forma
basis, no Event of Default, or event that after the giving of notice or lapse of
time or both would become an Event of Default, shall have occurred and be
continuing on the date of such deposit or during the period ending on the 123rd
day after the date of such deposit, and such deposit shall not result in a
breach or violation of, or constitute a default under, any other agreement or
instrument to which the Company is a party or by which the Company is bound,

          (e) if at such time the 2006 Notes or 2009 Notes, as the case may be,
are listed on a national securities exchange, the Company has delivered to the
Trustee an Opinion of Counsel to the effect that the 2006 Notes or 2009 Notes,
as the case may be, will not be delisted as a result of such deposit, defeasance
and discharge,

          (f) the Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit made by the Company pursuant to its
election under Sections 10.02 or 10.03 hereof was not made by the Company with
the intent of preferring the Holders of the 2006 Notes or 2009 Notes, as the
case may be, over the other creditors of the Company with the intent of
defeating, hindering, delaying or defrauding creditors of the Company or others,
and

          (g) the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent provided for relating to either the Legal Defeasance under Section
10.02 or the Covenant Defeasance under Section 10.03 (as the case may be) have
been complied with as contemplated by this Section 10.04.

         SECTION 10.05. Deposited Money and Government Securities to Be Held in
Trust; Other Miscellaneous Provisions. Subject to Section 10.06 hereof, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee pursuant to Section 10.04 hereof in respect of the outstanding
2006 Notes or 2009 Notes, as the case may be, shall be held in trust and applied
by the Trustee, in accordance with the provisions of such 2006 Notes or 2009
Notes, as the case may be, and this Indenture, to the payment, either directly
or through any paying agent

                                       45
<PAGE>   51



(including the Company acting as paying agent) as the Trustee may determine, to
the Holders of such 2006 Notes or 2009 Notes, as the case may be, of all sums
due and to become due thereon in respect of principal of, premium, if any, and
interest, but such money need not be segregated from other funds except to the
extent required by law.

         The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the money or U.S. Government
Obligations deposited pursuant to Section 10.04 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding 2006
Notes or 2009 Notes, as the case may be.

         Anything in this Article Ten to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the Company's
request any money or U.S. Government Obligations held by it as provided in
Section 10.04 hereof which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
10.04(a) hereof), are in excess of the amount thereof which would then be
required to be deposited to effect an equivalent Legal Defeasance or Covenant
Defeasance.

         SECTION 10.06. Repayment to Company. Any money deposited with the
Trustee or any paying agent, or then held by the Company, in trust for the
payment of the principal of, premium, if any, or interest on any 2006 Note or
2009 Note, as the case may be, and remaining unclaimed for two years after such
principal, premium, if any, or interest has become due and payable shall be paid
to the Company on its written request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such 2006 Note or 2009 Note, as
the case may be, shall thereafter, as an unsecured general creditor, look only
to the Company for payment thereof, and all liability of the Trustee or such
paying agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; provided, however, that the Trustee
or such paying agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in The New York Times and
The Wall Street Journal (national edition), notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such notification or publication, any unclaimed balance
of such money then remaining will be repaid to the Company.

         SECTION 10.07. Reinstatement. If the Trustee or paying agent is unable
to apply any money or U.S. Government Obligations in accordance with Section
10.02 or 10.03 hereof, as the case may be, by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, then the Company's obligations under this
Indenture and the 2006 Notes

                                       46
<PAGE>   52



or 2009 Notes, as the case may be, shall be revived and reinstated as though no
deposit had occurred pursuant to Section 10.02 or 10.03 hereof until such time
as the Trustee or paying agent is permitted to apply all such amounts in
accordance with Section 10.02 or 10.03 hereof, as the case may be; provided,
however, that, if the Company makes any payment of principal of, premium, if
any, or interest on any 2006 Note or 2009 Note, as the case may be, following
the reinstatement of its obligations, the Company shall be subrogated to the
rights of the Holders of such 2006 Note or 2009 Note, as the case may be, to
receive such payment from the amounts held by the Trustee or paying agent.

                                   ARTICLE 11
                            MISCELLANEOUS PROVISIONS

         SECTION 11.01. Incorporators, Stockholders, Officers, Directors,
Employees and Controlling Persons of Company Exempt from Individual Liability.
No recourse for the payment of the principal of, premium, if any, or interest on
any of the Securities or any claim based thereon or otherwise in respect
thereof, and no recourse under or upon any obligation, covenant or agreement of
the Company contained in this Indenture, or in any Security, or because of the
creation of any indebtedness evidenced thereby, shall be had against any
incorporator, as such, or against any past, present or future stockholder,
officer, director, employee or controlling person, as such, of the Company or of
any successor Person, either directly or through the Company or any successor
Person, under any rule of law, statute or constitutional provision or by the
enforcement of any assessment or by any legal or equitable proceeding or
otherwise, all such liability being expressly waived and released by the
acceptance of the Securities by the holders thereof and as part of the
consideration for the issue of the Securities.

         SECTION 11.02. Provisions of Indenture for the Sole Benefit of Parties
and Holders. Nothing in this Indenture or in the Securities, expressed or
implied, shall give or be construed to give to any person, firm or corporation,
other than the parties hereto and their successors and the holders of the
Securities, any legal or equitable right, remedy or claim under this Indenture
or under any covenant or provision herein contained, all such covenants and
provisions being for the sole benefit of the parties hereto and their successors
and of the holders of the Securities.

         SECTION 11.03. Successors and Assigns of Company Bound by Indenture.
All the covenants, stipulations, promises and agreements in this Indenture
contained by or in behalf of the Company shall bind its successors and assigns,
whether so expressed or not.

         SECTION 11.04. Notices and Demands on Company, Trustee and Holders. Any
notice or demand which by any provision of this Indenture is required or
permitted to be given or served by the Trustee or by the holders of Securities
to or on the Company may be given or served by being deposited postage prepaid,
first-class mail (except as otherwise specifically provided herein) addressed
(until another address of the Company is filed by the Company with the Trustee)
to USEC, Inc., 2 Democracy Center, 6903 Rockledge Drive, Bethesda, MD 20817,
Attention: Legal Department, with a copy to the Treasurer. Any notice,
direction, request or demand by the Company or any Securityholder to or upon the
Trustee shall be deemed to have been sufficiently given or made, for all
purposes, if given or made at the Corporate Trust Office.

         Where this Indenture provides for notice to Holders, such notice shall
be sufficiently given (unless otherwise herein expressly provided) if in writing
and mailed, first-class postage prepaid, to each Holder entitled thereto, at his
last address as it appears in the Security Register. In any case where notice to
Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. The Trustee may waive notice
to it of any provision herein, and such waiver shall be deemed to be for its
convenience and discretion. Waivers of notice by Holders shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

         In case, by reason of the suspension of or irregularities in regular
mail service, it shall be impracticable to mail notice to the Company and
Securityholders when such notice is required to be given pursuant to any
provision of this Indenture, then any manner of giving such notice as shall be
satisfactory to the Trustee shall be deemed to be a sufficient giving of such
notice.

         SECTION 11.05. Officers' Certificates and Opinions of Counsel;
Statements to Be Contained Therein. Upon any application or demand by the
Company to the Trustee to take any action under any of the provisions of this
Indenture, the Company shall furnish to the Trustee an Officers' Certificate
stating that all conditions precedent provided for in this Indenture relating to
the proposed action have been complied with and an Opinion of Counsel stating
that in the opinion of such counsel all such conditions precedent have been
complied with, except that in the case of any such application or demand as to
which the furnishing of such documents is specifically required by any provision
of this Indenture relating to such particular application or demand, no
additional certificate or opinion need be furnished.

         Each certificate or opinion provided for in this Indenture and
delivered to the Trustee with respect to compliance with a condition or covenant
provided for in this

                                       48
<PAGE>   54



Indenture shall include (a) a statement that the person making such certificate
or opinion has read such covenant or condition, (b) a brief statement as to the
nature and scope of the examination or investigation upon which the statements
or opinions contained in such certificate or opinion are based, (c) a statement
that, in the opinion of such person, he has made such examination or
investigation as is necessary to enable him to express an informed opinion as to
whether or not such covenant or condition has been complied with and (d) a
statement as to whether or not, in the opinion of such person, such condition or
covenant has been complied with.

         Any certificate, statement or opinion of an officer of the Company may
be based, insofar as it relates to legal matters, upon a certificate or opinion
of or representations by counsel, unless such officer knows that the certificate
or opinion or representations with respect to the matters upon which his
certificate, statement or opinion may be based as aforesaid are erroneous, or in
the exercise of reasonable care should know that the same are erroneous. Any
certificate, statement or opinion of counsel may be based, insofar as it relates
to factual matters or information which is in the possession of the Company,
upon the certificate, statement or opinion of or representations by an officer
or officers of the Company, unless such counsel knows that the certificate,
statement or opinion or representations with respect to the matters upon which
his certificate, statement or opinion may be based as aforesaid are erroneous,
or in the exercise of reasonable care should know that the same are erroneous.

         Any certificate, statement or opinion of an officer of the Company or
of counsel may be based, insofar as it relates to accounting matters, upon a
certificate or opinion of or representations by an accountant or firm of
accountants in the employ of the Company, unless such officer or counsel, as the
case may be, knows that the certificate or opinion or representations with
respect to the accounting matters upon which his certificate, statement or
opinion may be based as aforesaid are erroneous, or in the exercise of
reasonable care should know that the same are erroneous.

         Any certificate or opinion of any independent firm of public
accountants filed with the Trustee shall contain a statement that such firm is
independent.

         SECTION 11.06. Payments Due on Saturdays, Sundays and Holidays. If the
date of maturity of interest on or principal of the Securities or the date fixed
for redemption of any Security shall not be a Business Day, then payment of
interest or principal need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the date of
maturity or the date fixed for redemption, and no interest shall accrue for the
period after such date.

         SECTION 11.07. Conflict of Any Provision of Indenture with Trust
Indenture Act of 1939. If and to the extent that any provision of this Indenture
limits, qualifies or conflicts with another provision included in this Indenture
by operation of Sections

                                       49
<PAGE>   55



310 to 317, inclusive, of the Trust Indenture Act of 1939 (an "INCORPORATED
PROVISION"), such incorporated provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act which
may be so modified or excluded, the Trust Indenture Act provision shall be
deemed to apply to this Indenture as so modified or shall be excluded from
applying to the Indenture as the case may be.

         SECTION 11.08. New York Law to Govern. This Indenture and each Security
shall be deemed to be a contract under the laws of the State of New York, and
for all purposes including the obligations of the Company and the rights of
holders of the Securities arising out of or in connection with the Securities,
including the obligations of the Company to pay all principal, interest or other
amounts payable under the Indenture and such Security, will be governed by and
shall be construed in accordance with the laws of said State, without giving
effect to the conflict of laws provisions thereof, except as may otherwise be
required by mandatory provisions of law.

         SECTION 11.09.  Counterparts.  This Indenture may be executed in any
number of counterparts, each of which shall be an original; but such
counterparts shall together constitute but one and the same instrument.

         SECTION 11.10.  Effect of Headings.  The Article and Section headings
herein and the Table of Contents are for convenience only and shall not affect
the construction hereof.

                           [ ]% Senior Note Due 200[ ]

         USEC Inc., a Delaware corporation (the "COMPANY"), for value received
hereby promises to pay to [ ] or registered assigns the principal sum of [ ]
Dollars at the Company's office or agency for said purpose in The City of New
York, on January 20, 200[ ], in such coin or currency of the United States of
America as at the time of payment shall be legal tender for the payment of
public and private debts, and to pay interest, semi-annually on January 20 and
July 20 (each an "INTEREST PAYMENT DATE") of each year, commencing with July 20,
1999, on said principal sum in like coin or currency at the rate per annum set
forth above at said office or agency from the most recent Interest Payment Date
to which interest on the Securities has been paid or duly provided for, unless
the date hereof is a date to which interest on the Securities has been paid or
duly provided for, in which case from the date of this Security. Notwithstanding
the foregoing, if the date hereof is after December 30 or June 30 (each a
"REGULAR RECORD DATE"), as the case may be, and before the immediately following
Interest Payment Date, this Security shall bear interest from such Interest
Payment Date; provided, that if the Company shall default in the payment of
interest due on such Interest Payment Date then this Security shall bear
interest from the next preceding Interest Payment Date to which interest on the
Securities has been paid or duly provided for. The interest so payable on any
Interest Payment Date will, except as otherwise provided in the Indenture
referred to on the reverse hereof, be paid to the person in whose name this
Security is registered at the close of business on the Regular Record Date
preceding such Interest Payment Date whether or not such day is a business day;
provided that interest may be paid, at the option of the Company, by mailing a
check therefor payable to the registered holder entitled thereto at such
holder's last address as it appears on the Security register or by wire
transfer, in immediately available funds, to such bank or other entity in the
continental United States as shall be designated in writing by such holder prior
to the relevant Regular Record Date and shall have appropriate facilities for
such purpose, or in accordance with the standard operating procedures of the
Depositary (as defined in the Indenture).

         Interest, other than default interest, on the Securities will be
computed on the basis of a 360-day year consisting of twelve 30-day months.

         Reference is made to the further provisions set forth on the reverse
hereof. Such further provisions shall for all purposes have the same effect as
though fully set forth at this place.

                          [FORM OF REVERSE OF SECURITY]

                                    USEC Inc.

                           [ ]% Senior Note Due 200[ ]

         This Security is one of a duly authorized issue of debt securities of
the Company, limited to the aggregate principal amount of $[ ], issued or to be
issued pursuant to an indenture dated as of January 15, 1999 (the "INDENTURE"),
duly executed and delivered by the Company to First Union National Bank, as
Trustee (herein called the "TRUSTEE"). Reference is hereby made to the Indenture
and all indentures supplemental thereto for a description of the rights,
limitations of rights, obligations, duties and immunities thereunder of the
Trustee, the Company and the holders (the words "HOLDERS" or "HOLDER" meaning
the registered holders or registered holder) of the Securities.

         This Security will bear interest until final maturity at a rate per
annum shown above, except as provided in the next paragraph. The Company will
pay interest on overdue principal of, premium, if any, and to the extent lawful,
interest on overdue installments of interest, at a [ ]% rate per annum based on
a 360-day year consisting of twelve 30-day months.

         In case an Event of Default (as defined in the Indenture) shall have
occurred and be continuing, the principal of all the Securities may be declared
due and payable, in the manner and with the effect, and subject to the
conditions, provided in the Indenture. The Indenture provides that in certain
events such declaration and its consequences may be waived by the holders of a
majority in aggregate principal amount of the Securities then outstanding and
that, prior to any such declaration, such holders may waive any past default
under the Indenture and its consequences except a default in the payment of
principal of, premium, if any, or interest on any of the Securities. Any such
consent or waiver by the holder of this Security (unless revoked as provided in
the Indenture) shall be conclusive and binding upon such holder and upon all
future holders and owners of this Security and any Security which may be issued
in exchange or substitution herefor, whether or not any notation thereof is made
upon this Security or such other Securities.

         The Indenture permits the Company and the Trustee, with the consent of
the holders of at least a majority in aggregate principal amount of the
Securities at the time outstanding, evidenced as in the Indenture provided, to
execute supplemental indentures adding any provisions to or changing in any
manner or eliminating any of the provisions of the Indenture or of any
supplemental indenture or modifying in any manner the rights of the holders of
the Securities; provided that no such modification or amendment may, without the
consent of each holder affected thereby, (i) change the Stated Maturity (as
defined in the Indenture) of the principal of, or any installment of interest
on, any Security, (ii) reduce the principal amount of, or



                                       A-4


<PAGE>   61



premium, if any, or any interest on, any Security, (iii) reduce the amount of
principal of any Security payable upon acceleration of the maturity thereof,
(iv) change the place or currency of payment of principal of, premium, if any,
or interest on, any Security, (v) impair the right to institute suit for the
enforcement of any payment on or with respect to any Security, (vi) reduce the
above-stated percentage of outstanding Securities the consent of whose holders
is necessary to modify or amend the Indenture, (vii) reduce the percentage in
principal amount of outstanding Securities the consent of whose holders is
necessary for waiver of compliance with certain provisions of the Indenture or
for waiver of certain defaults, or (viii) modify any provision of the Indenture
with respect to modification and waiver.

         Notwithstanding the foregoing, without the consent of any holder of
Securities, the Company and the Trustee may amend or supplement the Indenture or
the Securities to cure any ambiguity, defect or inconsistency, to provide for
uncertificated Securities in addition to or in place of certificated Securities,
to provide for the assumption of the Company's obligations to holders of
Securities in the case of a merger or consolidation, to make any change that
would provide any additional rights or benefits to the holders of Securities or
that does not adversely affect the legal rights under the Indenture of any such
holder, or to comply with requirements of the Commission (as defined in the
Indenture) in order to effect or maintain the qualification of the Indenture
under the Trust Indenture Act of 1939 (as defined in the Indenture).

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of, premium, if any, and
interest on this Security at the place, times, and rate, and in the currency,
herein prescribed.

         The Securities are issuable only as registered Securities without
coupons in denominations of $1,000 and any integral multiple of $1,000.

         At the office or agency of the Company referred to on the face hereof
and in the manner and subject to the limitations provided in the Indenture,
Securities may be exchanged for a like aggregate principal amount of Securities
of other authorized denominations.

         Upon due presentment for registration of transfer of this Security at
the above-mentioned office or agency of the Company, a new Security or
Securities of authorized denominations, for a like aggregate principal amount,
will be issued to the transferee as provided in the Indenture. No service charge
shall be made for any such transfer, but the Company may require payment of a
sum sufficient to cover any tax or other similar governmental charge that may be
imposed in connection therewith.

         The Securities may be redeemed at the option of the Company, in whole
or in part, in principal amounts of $1,000 or any integral multiple thereof at
any time,


                                       A-5


<PAGE>   62



upon mailing a notice of such redemption by first class mail not less than 30
nor more than 60 days prior to the Redemption Date, all as provided in the
Indenture, at a redemption price equal to the sum of (i) an amount equal to 100%
of the principal amount thereof and (ii) the Make-Whole Premium, together with
accrued and unpaid interest up to but not including the Redemption Date.

         Subject to payment by the Company of a sum sufficient to pay the amount
due on redemption, interest on this Security (or portion hereof if this Security
is redeemed in part) shall cease to accrue upon the date duly fixed for
redemption of this Security (or portion hereof if this Security is redeemed in
part).

         The Company, the Trustee, and any authorized agent of the Company or
the Trustee, may deem and treat the registered holder hereof as the absolute
owner of this Security (whether or not this Security shall be overdue and
notwithstanding any notation of ownership or other writing hereon made by anyone
other than the Company or the Trustee or any authorized agent of the Company or
the Trustee), for the purpose of receiving payment of, or on account of, the
principal hereof and premium, if any, and, subject to the provisions on the face

      THIS AGREEMENT is made as of June 9, 1999, by and between USEC Inc., a
corporation organized and existing under the laws of the state of Delaware
(hereinafter called "USEC"), and James R. Mellor, an individual (hereinafter
called the "Consultant").

      IN CONSIDERATION of the mutual promises set forth herein, the parties
hereby agree as follows:

1.    The term of this Agreement shall be from July 28, 1999 through July 27,
2000, unless sooner terminated pursuant to the terms hereof.

2.    While this Agreement is in effect, the Consultant shall perform certain
work and services relating to USEC's policies, procedures, commercial
practices, external affairs, strategic planning under the terms and
conditions hereinafter set forth.

3.    While this Agreement is in effect, USEC shall compensate the Consultant
at a fixed price of Two Hundred Fifty-Five Thousand Dollars ($255,000),
payable in 12 equal monthly installments to be paid thirty (30) days after
the last of each month falling, in whole or in part, during the term of this
Agreement, excluding July 1999.  USEC shall reimburse the Consultant for
reasonable and necessary travel and living expenses incurred by the
Consultant in the performance of the services described herein.  Compensation
for expenses shall be made once monthly upon the Consultant's furnishing to
USEC a written statement specifying such expenses.  Payment terms shall be

4.    In the performance of the work and services hereunder, the Consultant
shall act solely as an independent contractor and not as an employee of
USEC.  All taxes applicable to any amounts paid by USEC to the Consultant
under this Agreement shall be the Consultant's liability and USEC shall not
withhold nor pay any amounts for federal, state or municipal income tax,
special security, unemployment or worker's compensation.  In accordance with
current law, USEC shall annually file with the Internal Revenue Service a
Form 1099-MISC, U.S. Information Return for Recipients of Miscellaneous
Income, reflecting the gross annual payments by USEC to the Consultant
pursuant to this Agreement, net of any reimbursed expenses incurred by the

5.    All reports, findings, recommendations, data, memoranda or documents,
arising of out and relating to the services performed under this Agreement
are (and shall continue to be after the expiration of this Agreement) the
property of USEC or its assigns, and USEC shall have the exclusive rights to
such materials.  The use of these materials in any manner by USEC or its
assigns shall not result in any additional claim for compensation by the
Consultant.  The Consultant shall

<PAGE>   2


hold confidential all information developed by or communicated to the
Consultant in the performance of the services, whether described in this
Agreement, in any scheduled executed pursuant hereto or otherwise, other than
information that is already in the public domain or that becomes publicly
available other than through an unauthorized disclosure by the Consultant.
Nothing herein shall preclude disclosure of confidential information to
officers, employees or directors of USEC and its subsidiaries and affiliates,
or to attorneys, advisers and consultants of USEC who are under an obligation
to USEC to keep such information confidential.

6.    By entering into this Agreement with USEC, the Consultant represents
that he presently has no conflicting interests, agreements or obligations
with any other party.  The Consultant shall promptly notify USEC in writing
if a change in circumstances creates, or appears likely to create, a conflict
with the Consultant's obligations hereunder or an appearance that such a
conflict exists.

7.    The Consultant hereby releases USEC from any and all liability for
damage to property or loss thereof, personal injury or death during the term
of this Agreement (and any extensions thereof) or thereafter, sustained by
the Consultant as a result of performing the services under this Agreement or
arising out of the performance of such services; provided, however, that the
foregoing release shall not apply to the extent such damage, loss, injury or
death is caused by or results from the negligence of USEC, its agents or
employees.  Nothing herein shall deemed to limit the obligation of USEC, or
any USEC subsidiary or affiliate, to indemnify the Consultant under USEC's
articles of incorporation or by-laws or under any indemnification agreement
entered into with the Consultant concerning the Consultant's services as a
director of USEC or any USEC subsidiary or affiliate.

8.    If the services to be performed by the Consultant include access to
classified material or areas, the Consultant shall comply with all applicable
security laws, regulations, orders and requirements.  The Consultant shall
submit a confidential report to USEC immediately whenever for any cause he
has reason to believe that there is either (a) an active danger of espionage
or sabotage affecting any work under such government contracts, or (b) a
violation or threatened violation of any applicable security law, regulation,
order or requirement concerning the classified material or areas.

9.    Either party may terminate this Agreement, for any reason or no reason,
at any time by a written notice to the other party.  Such termination shall
take effect immediately upon receipt of a termination notice by the other
party, unless a different termination date is stated in the notice.  Upon
termination of the Agreement, all work and services being performed under
this Agreement shall cease.  USEC shall have no liability or obligation for
any performance by the Consultant after a termination takes effect.

10.   The Consultant may not assign this Agreement, nor may the Consultant
delegate or subcontract the performance or obligations imposed hereunder
without the consent of  USEC.

11.   The Consultant has no authority whatever, express or implied, by virtue
of this Agreement to commit USEC in any way to perform in any manner or to
pay money for services or material.

                              EMPLOYMENT AGREEMENT

            THIS EMPLOYMENT AGREEMENT made and entered into as of the 28th
day of April, 1999, by and between USEC Inc., a Delaware corporation (the

            WHEREAS, the Company desires to provide for the service and
employment of the Executive with the Company and the Executive wishes to perform
services for the Company, all in accordance with the terms and conditions
provided herein;

            NOW, THEREFORE, IN CONSIDERATION of the mutual premises, covenants
and agreements set forth below, it is hereby agreed as follows:

      1.    Employment and Term.

      (a) The Company agrees to employ the Executive, and the Executive agrees
to remain in the employ of the Company in accordance with the terms and
provisions of this Agreement for the period set forth below (the "Employment
Period").

      (b) The Employment Period of this Agreement will commence as of the date
hereof (the "Effective Date") and continue until the fifth anniversary of the

terminated as hereinafter provided. The Employment Period shall automatically be
extended for one additional year from the Fifth Anniversary unless either party
shall have given notice to the other party, at least six months prior to such
Fifth Anniversary, that it does not wish to extend the Employment Period.
Notwithstanding the foregoing, upon the occurrence of a "Change in Control," as
defined in the USEC Inc. 1999 Equity Incentive Plan (the "Equity Incentive

Executive Officer of the Company and shall have such responsibilities, duties
and authority as are specified in the Company's charter and/or bylaws and as
specified, from time to time, by the Board. The Executive shall report directly
to the Board. The Executive shall devote substantially all of his working time
and efforts to the business and affairs of the Company and shall not engage in
activities that interfere with such performance; provided, however, that this
Agreement shall not be interpreted to prohibit the Executive from managing his
personal investments and affairs, engaging in charitable activities, serving as
a member of any board of directors of which he is currently a member or,
subject to prior approval of the Board, serving on any other board of directors
so long as, in the reasonable determination of the Board, such activities do
not interfere with the performance of his duties hereunder.

      3. Compensation. The Executive shall receive the following compensation
for his services hereunder to the Company:

      (a) Salary. Commencing as of the Effective Date and continuing during the
Employment Period, the Company shall pay to the Executive an annual base salary
("Annual Base Salary") at a rate not less than $600,000 for the Company's 1999
fiscal year, such salary to be paid in conformity with the Company's policies
relating to salaried employees. This salary may be (but is not required to be)
increased from time to time, subject to and in accordance with an annual
performance review by the Board.

      (b) Annual Incentive Program. The Executive shall be a participant in the
Company's annual incentive program as in effect from time to time (the "Annual
Incentive Program") at a level commensurate with his position, and shall be
entitled to receive such amounts (each, a "Bonus") as may be authorized,
declared and paid by the Company pursuant to the terms of such program and the
performance goals established by the Compensation Subcommittee of the Board.

      (c) Long-Term Incentive Plan. The Executive shall be a participant in the
Company's Equity Incentive Plan, and any other long-term equity or cash
compensation programs as the Board may provide for the Company's senior
management (collectively, the "LTIP") at a level commensurate with the
Executive's position.

      (d) Employee Benefit Plans; Perquisites; Fringe Benefits. During the
Employment Period, the Executive shall be eligible to participate, on a basis
commensurate with his position, in all employee benefit plans, including
supplemental benefit plans, welfare plans, practices, policies and programs,

      (e) Life Insurance. The Company shall provide the Executive with an amount
of term life insurance equal to 3-1/3 times his Annual Base Salary as of the
Effective Date. The Company shall pay the premiums for such insurance until the
Date of Termination, at which time the Company's obligations to pay such
premiums shall terminate; provided, however, that in the event that the
Executive's employment is terminated by the Company (other than for Cause, as
hereinafter defined), or by the Executive for Good Reason, as hereinafter
defined, the Company shall pay up the insurance policy in full, and transfer
ownership of such policy to the Executive, to the extent permitted by such
policy.

      (f) Expenses. The Company agrees to reimburse the Executive for all
reasonable expenses, including those for travel and entertainment, properly
incurred by him in the performance of his duties under this Agreement in
accordance with policies established from time to time by the Company.

      4.    Termination of Employment.

      (a) Death; Disability. The Executive's employment shall terminate
automatically upon the Executive's death during the Employment Period. The
Company or the Executive may terminate the Executive's employment on account of
the Executive's Disability. For purposes hereof, "Disability" shall mean that

described in the Company's long term disability benefit plan applicable to
senior executive officers as in effect at the time the Executive's disability is
incurred.

      (b) By the Company for Cause. The Company may terminate the Executive's
employment during the Employment Period for Cause. For purposes of this
Agreement "Cause" shall mean:

            (i)   the engaging by the Executive in willful misconduct that is
      injurious to the Company or its affiliates;

            (ii) the embezzlement or misappropriation of funds or property of
      the Company or its affiliates by the Executive, or the conviction of the
      Executive of a felony or the entrance of a plea of guilty or nolo
      contendere by the Executive to a felony; or

            (iii) the willful failure or refusal by the Executive to
      substantially perform his duties or responsibilities (other than (x) any
      such failure resulting from the Executive's incapacity due to Disability,
      after demand for substantial performance is delivered by the Company to
      the Executive that specifically identifies the manner in which the Company
      believes the Executive has not substantially performed his duties, or (y)
      any such actual or anticipated failure after the issuance of a Notice of
      Termination (as defined below) by the Executive for Good Reason (as
      defined below)).



                                     -3-
<PAGE>   4



For purposes of this definition, no act, or failure to act, on the Executive's
part shall be considered "willful" unless done, or omitted to be done, by him
not in good faith and without reasonable belief that his action or omission was
in the best interest of the Company. Notwithstanding the foregoing, the
Executive's employment shall not be deemed to have been terminated for Cause
unless (A) a reasonable notice shall have been given to him setting forth in
reasonable detail the reasons for the Company's intentions to terminate for
Cause, and if such termination is pursuant to clause (i) or (iii) above, and the
damage to the Company is curable, only if the Executive has been provided a
period of ten (10) business days from receipt of such notice to cease the
actions or inactions, and he has not done so; (B) an opportunity shall have been
provided for the Executive together with his counsel, to be heard before the
Board; and (C) if such termination is pursuant to clause (i) or (iii) above,
delivery shall have been made to the Executive of a Notice of Termination from
the Board finding that in the good faith opinion of a majority of the
nonmanagement members of the Board he was guilty of conduct set forth in clause
(i) or (iii) above, and specifying the particulars thereof in reasonable detail.
Any determination of Cause made by the Company in accordance with the foregoing
procedure shall be made by the Company, in its sole discretion. Any such
determination shall be final and binding on the Executive.

      (c) By the Executive for Good Reason. The Executive may terminate his
employment during the Employment Period for Good Reason. For purposes of this
Agreement, "Good Reason" shall mean, without the Executive's express written
consent, any of the following, unless such act or failure to act is corrected
prior to the Date of Termination specified in the Notice of Termination given in
respect thereof:

            (i) any material breach by the Company of its obligations under this
      Agreement, including but not limited to (x) a reduction in the Executive's
      Base Salary as such salary may be increased from time to time thereafter,
      and (y) the Company's requiring the Executive to be based anywhere other
      than the offices that constitute the Company's corporate headquarters
      and/or the Company's principal executive offices;

            (ii) the Executive is removed from any of his positions set forth in
      Section 2 hereof for any reason other than (A) by reason of death or
      Disability, or (B) for Cause, or the failure to elect or re-elect the
      Executive to any position with the Company (including membership on the
      Board or the Board of Directors of the Subsidiaries);

            (iii) the Executive is assigned any duties inconsistent with the
      Executive's position (including status, offices, titles and reporting
      relationships), authority, duties or responsibilities as in effect as of
      the Effective Date (excluding for this purpose an isolated, insubstantial
      and inadvertent action not taken in bad faith and which is remedied by the
      Company promptly following notice thereof given by the Executive);

            (iv) the failure to assume this Agreement by any successor to the
      Company;



                                     -4-
<PAGE>   5


            (v) any purported termination of the Executive's employment that is
      not effected pursuant to a Notice of Termination satisfying the
      requirements of paragraph (d) below, which termination for purposes of
      this Agreement shall be ineffective; or

            (vi) termination of employment by the Executive that is determined
      by a majority of the nonmanagement members of the Board to be deemed to
      constitute Good Reason.

Notwithstanding the foregoing, a termination shall not be treated as a
termination for Good Reason unless the Executive shall have delivered a Notice
of Termination within 90 days of the Executive's having actual knowledge of the
occurrence of one of such events, stating that the Executive intends to
terminate employment for Good Reason. For purposes of this Agreement, any good
faith determination of "Good Reason" made by the Executive shall be conclusive.

      (d) Notice of Termination. Any termination of the Executive's employment
(other than by reason of death) shall be communicated by Notice of Termination
to the other party hereto in accordance with Section 11(b) of this Agreement.
For purposes of this Agreement, a "Notice of Termination," means a written
notice that indicates the specific termination provision in this Agreement
relied upon, sets forth in reasonable detail the facts and circumstances claimed
to provide a basis for termination of the Executive's employment under the
provision so indicated, and specifies the Date of Termination. The failure by
the Executive or the Company to set forth in the Notice of Termination any fact
or circumstance that contributes to a showing of Good Reason or Cause shall not
waive any right of the Executive or the Company under this Agreement or preclude
the Executive or the Company from asserting such fact or circumstance in
enforcing the Executive's or the Company's rights under this Agreement.

      (e) Date of Termination. "Date of Termination" shall mean:

                  (i) if the Executive's employment is terminated by reason of
      Disability, or by the Executive for Good Reason, other than a termination
      pursuant to Section 4(c)(iv) of the definition of Good Reason, the date
      specified in the Notice of Termination (which shall not be less than 30
      nor more than 60 days from the date such Notice of Termination is given);

                  (ii) if the Executive's employment is terminated by the
      Company for Cause or without Cause, or by the Executive for other than
      Good Reason, the date the Notice of Termination is received;

                  (iii) if the Executive's employment is terminated by the
      Executive for Good Reason pursuant to Section 4(c)(iv) hereof, the date
      upon which any succession referred to therein becomes effective;



                                     -5-
<PAGE>   6


                  (iv) if the Executive's employment is terminated by reason of
      death, the date of death; and

                  (v) if the Executive's employment is terminated by reason of
      the expiration of the Employment Period, the last day of the Employment
      Period.

            5.     Obligations of the Company upon Termination.

            (a) Termination by the Executive for Good Reason or by the Company
Other than for Cause. If the Executive's employment is terminated by the
Executive for Good Reason or by the Company other than for Cause:

                        (i) the Company shall pay to the Executive, within 10
      days following the Date of Termination, a lump sum amount in cash equal
      to the sum of:

                        (A) the Executive's Annual Base Salary through the Date
            of Termination to the extent not previously paid;

                        (B) an amount equal to the target Bonus for the fiscal
            year prior to the Date of Termination, to the extent such Bonus has
            been earned but not paid, and for the fiscal year that includes the
            Date of Termination. the target Bonus multiplied by a fraction, the
            numerator of which shall be the number of days from the beginning of
            such fiscal year to and including the Date of Termination and the
            denominator of which shall be three hundred and sixty-five (365);
            and

                        (C) any compensation previously deferred by the
            Executive (together with any accrued interest or earnings thereon)
            and any accrued vacation pay, in each case to the extent not
            previously paid.

      The amounts specified in clauses (A), (B) and (C) hereof shall be
      hereinafter referred to as the "Accrued Obligations";

                  (ii) the Company shall pay to the Executive, within 10 days
      following the Date of Termination, a lump sum amount, in cash, equal to
      three times the sum of the Final Average Salary and the Final Average
      Bonus, where (A) the "Final Average Salary" means the average of the
      Executive's Annual Base Salary as in effect for each of the three years
      preceding the Date of Termination and commencing no earlier than February
      3, 1999 (or, if shorter, the number of years from February 3, 1999 to the
      Date of Termination) and (B) the "Final Average Bonus" means the average
      of the Bonuses awarded to the Executive pursuant to the Annual Incentive
      Program with respect to the three years preceding the Date of Termination
      and commencing no earlier than February 3, 1999 (or, if shorter, the
      number of years from February 3, 1999 to the Date of Termination);

                  (iii) subject to the Executive's continued compliance with
      Section 9 hereof, the Company shall continue life, disability, accident
      and health insurance benefits (including supplemental health and life
      insurance benefits) substantially similar to those that the Executive was
      receiving immediately prior to the Date of Termination (or if applicable,
      prior to the Change in Control, or thereafter, if higher) until the
      earlier to occur of (i) the third anniversary of the Date of Termination
      or (ii) such time as the Executive is covered by comparable programs of a
      subsequent employer; provided, however, that in the event the Company is
      unable to provide such benefits, the Company shall make annual payments to
      the Executive in an amount such that following the Executive's payment of
      applicable taxes thereon, the Executive retains an amount equal to the
      cost to the Executive, net of any cost that would otherwise be borne by
      the Executive, of obtaining comparable life, disability, accident and
      health insurance coverage. Benefits otherwise receivable by the Executive
      pursuant to this Section 5(a)(iii) shall be reduced to the extent
      comparable benefits are actually received during the three year period
      following termination, and any such benefits actually received by the
      Executive shall be reported to the Company;

                  (iv) the Company shall furnish the Executive with office space
      and administrative support for two years following the Date of
      Termination; provided, however, that if the Executive becomes employed
      with another employer, the Company shall cease to provide the Executive
      with such office space and administrative support;

                  (v) the Company shall credit the Executive with three
      additional years of service for purposes of the SERP so that the
      Executive's SERP benefit will be calculated as if the Executive were three
      years older at the Date of Termination; and

                  (vi) all of the Executive's stock options (vested or
      nonvested) shall become exercisable and shall remain exercisable for the
      longer of one year and the number of years, including fractional portions
      thereof, that would have remained in the Employment Period until its
      expiration, but in no event shall such period exceed the term of the stock
      options; and all restrictions pertaining to the Executive's restricted
      stock or other equity based awards shall lapse on the Date of Termination.

            In addition, if the Company terminates the Executive's employment
for other than Cause, or the Executive terminates employment for Good Reason,
then the Executive agrees to make himself available to consult with the Company
with respect to general business matters and strategic issues as reasonably
requested by the Company for such period of time following the Date of
Termination, and in accordance with such other terms and conditions, as are
mutually agreed upon by the parties hereto.

            (b) Termination By Reason of Death or Disability. If the Executive's
employment shall be terminated by reason of the Executive's death or Disability,
then the

                                     -7-
<PAGE>   8

Company shall pay the Executive the amounts and benefits described in clauses
(a)(i) through (iii), (v) and (vi) above.

            (c) Termination By Reason of Expiration of the Employment Period. If
the Executive's employment shall be terminated by reason of the expiration of
the Employment Period:

                  (i) the Company shall pay to the Executive, within 10 days
      following the Date of Termination, the Accrued Obligations;

                  (ii) the Company shall pay to the Executive, within 10 days
      following the Date of Termination, a lump sum amount, in cash, equal to
      one and one-half times the sum of the Final Average Salary and the Final
      Average Bonus;

                  (iii) subject to the Executive's continued compliance with
      Section 9 hereof, the Company shall continue life, disability, accident
      and health insurance benefits (including supplemental health and life
      insurance benefits) substantially similar to those that the Executive was
      receiving immediately prior to the Date of Termination until the earlier
      to occur of (i) the last day of the 18th month following the Date of
      Termination or (ii) such time as the Executive is covered by comparable
      programs of a subsequent employer; provided, however, that in the event
      the Company is unable to provide such benefits, the Company shall make
      annual payments to the Executive in an amount such that following the
      Executive's payment of applicable taxes thereon, the Executive retains an
      amount equal to the cost to the Executive, net of any cost that would
      otherwise be borne by the Executive, of obtaining comparable life,
      disability, accident and health insurance coverage. Benefits otherwise
      receivable by the Executive pursuant to this Section 5(c)(iii) shall be
      reduced to the extent comparable benefits are actually received during the
      one and one-half year period following termination, and any such benefits
      actually received by the Executive shall be reported to the Company;

                  (iv) the Company shall furnish the Executive with office space
      and administrative support for one year following the Date of Termination;
      provided, however, that if the Executive becomes employed with another
      employer, the Company shall cease to provide the Executive with such
      office space and administrative support;

                  (v) the Company shall credit the Executive with one and
      one-half additional years of service for purposes of the SERP so that the
      Executive's SERP benefit will be calculated as if the Executive were one
      and one-half years older at the Date of Termination; and

                  (vi) all of the Executive's stock options shall become
      exercisable and shall remain exercisable for the longer of one year and
      the number of years, including fractional portions thereof, that would
      have remained in the Employment Period until its



                                     -8-
<PAGE>   9


      expiration, but in no event shall such period exceed the term of the
      stock options; and all restrictions pertaining to the Executive's
      restricted stock or other equity based awards shall lapse on the Date of
      Termination.

            In addition, if the Executive's employment is terminated by reason
of the expiration of the Employment Period, then the Executive agrees to make
himself available to consult with the Company with respect to general business
matters and strategic issues as reasonably requested by the Company for such
period of time following the Date of Termination, and in accordance with such
other terms and conditions, as are mutually agreed upon by the parties hereto.

            (d) Termination by the Company for Cause or By the Executive for
Other than Good Reason. Subject to the provisions of Section 6 of this
Agreement, if the Executive's employment shall be terminated by the Company for
Cause or by the Executive for other than Good Reason, death or Disability, in
either case, during the Employment Period, the Company shall have no further
obligations to the Executive under this Agreement other than the obligation to
pay to the Executive Annual Base Salary through the Date of Termination, earned
bonuses and any amount of compensation previously deferred by the Executive, in
each case to the extent previously unpaid, and the Executive shall have no
further obligations to the Company under this Agreement other than pursuant to
Section 9(a) of this Agreement. All of the Executive's stock options that have
not yet become exercisable shall expire and all of the Executive's restricted
stock awards and other restricted equity based awards as to which the applicable
restrictions have not yet lapsed shall be forfeited on the Date of Termination.

            (e) Certain Tax Consequences. Whether or not the Executive becomes
entitled to the payments and benefits described in this Section 5, if any of the
payments or benefits received or to be received by the Executive in connection
with a change in ownership or control of the Company (a "Statutory Change in
Control"), as defined in section 280G of the Internal Revenue Code of 1986, as
amended (the "Code"), or the Executive's termination of employment (whether
pursuant to the terms of this Agreement or any other plan, arrangement or
agreement with the Company, any person whose actions result in a Statutory
Change in Control or any person affiliated with the Company or such person)
(collectively, the "Severance Benefits") will be subject to any excise tax (the
"Excise Tax") imposed under section 4999 of the Internal Revenue Code of 1986,
as amended (the "Code"), the Company shall pay to the Executive an additional
amount equal to the Excise Tax (the Excise Tax Payment").

            For purposes of determining whether any of the Severance Benefits
will be subject to the Excise Tax and the amount of such Excise Tax:

                  (i) all of the Severance Benefits shall be treated as
      "parachute payments" within the meaning of Code section 280G(b)(2), and
      all "excess parachute payments" within the meaning of Code section
      280G(b)(1) shall be treated as subject to the Excise Tax, unless, in the
      opinion of tax counsel selected by the Company's



                                        -9-
<PAGE>   10


      independent auditors and reasonably acceptable to the Executive, such
      other payments or benefits (in whole or in part) do not constitute
      parachute payments, including by reason of Code section 280G(b)(4)(A), or
      such excess parachute payments (in whole or in part) represent reasonable
      compensation for services actually rendered, within the meaning of Code
      section 280G(b)(4)(B), in excess of the "Base Amount" as defined in Code
      section 280G(b)(3) allocable to such reasonable compensation, or are
      otherwise not subject to the Excise Tax; and

                  (ii) the value of any non-cash benefits or any deferred
      payment or benefit shall be determined by the Company's independent
      auditors in accordance with the principles of Code section 280G(d)(3) and
      (4).

            In the event that the Excise Tax is subsequently determined to be
less than the amount taken into account hereunder at the time of termination of
the Executive's employment, the Executive shall repay to the Company, at the
time that the amount of such reduction in Excise Tax is finally determined (the
"Reduced Excise Tax"), the difference of the Excise Tax Payment and the Reduced
Excise Tax. In the event that the Excise Tax is determined to exceed the amount
taken into account hereunder at the time of the termination of the Executive's
employment (including by reason of any payment the existence or amount of which
could not be determined at the time of the Excise Tax Payment), the Company
shall make an additional Excise Tax payment in respect of such excess (plus any
interest or penalties payable by the Executive with respect to such excess) at
the time that the amount of such excess is finally determined. The Executive and
the Company shall each reasonably cooperate with the other in connection with
any administrative or judicial proceedings concerning the existence or amount of
liability for Excise Tax with respect to the Severance Benefits.

            (f) Other Fees and Expenses. With respect to a termination of
Executive's employment prior to a Change in Control, the prevailing party shall
be entitled to recover from the other party to this Agreement, all reasonable
legal fees and expenses incurred in contesting or disputing any termination of
employment or in seeking to obtain or enforce any right or benefit to which such
party is entitled under this Agreement. With respect to a termination of
Executive's employment following a Change in Control, the Company shall bear its
own legal fees and expenses in connection with any such dispute, but the Company
shall pay the Executive's reasonable legal fees and expenses if the Executive is
the prevailing party in connection with any such dispute.

      6. Non-Exclusivity of Rights. Nothing in this Agreement shall prevent or
limit the Executive's continuing or future participation in any benefit plan,
program, policy or practice provided by the Company and for which the Executive
may qualify (except with respect to any benefit to which the Executive has
waived his rights in writing), nor shall anything herein limit or otherwise
affect such rights as the Executive may have under any other contract or
agreement entered into after the Effective Date with the Company. Amounts that
are vested benefits or that the Executive is otherwise entitled to receive
under any benefit plan, policy, practice or program



                                     -10-
<PAGE>   11



of, or any contract or agreement entered into after the date hereof with, the
Company at or subsequent to the Date of Termination, shall be payable in
accordance with such benefit plan, policy, practice, program, contract or
agreement, except as explicitly modified by this Agreement.

      7. Full Settlement; Mitigation. The Company's obligation to make the
payments provided for in this Agreement and otherwise to perform its
obligations hereunder shall not be affected by any set-off, counterclaim,
recoupment, defense or other claim, right or action that the Company may have
against the Executive or others. The Executive shall not be required to
mitigate the amount of any payment or benefit provided for in Sections 3(e) and
5 hereof by seeking other employment or otherwise, nor (except as specifically
provided in Section 5 hereof) shall the amount of any payment or benefit
provided for in Sections 3(e) and 5 hereof be reduced by any compensation
earned by the Executive as the result of employment by another employer or by
retirement benefits after the Date of Termination, or otherwise.

      8. Arbitration. Except as otherwise provided in Section 9 hereof, the
parties agree that any dispute, claim, or controversy based on common law,
equity, or any federal, state, or local statute, ordinance, or regulation
(other than workers' compensation claims) arising out of or relating in any way
to the Executive's employment, the terms, benefits, and conditions of
employment, or concerning this Agreement or its termination and any resulting
termination of employment, including whether such dispute is arbitrable, shall
be settled by arbitration. This agreement to arbitrate includes but is not
limited to all claims for any form of illegal discrimination, improper or
unfair treatment or dismissal, and all tort claims. The Executive shall still
have a right to file a discrimination charge with a federal or state agency,
but the final resolution of any discrimination claim shall be submitted to
arbitration instead of a court or jury. The arbitration proceeding shall be
conducted under the employment dispute resolution arbitration rules of the
American Arbitration Association in effect at the time a demand for arbitration
under the rules is made. The decision of the arbitrator(s), including
determination of the amount of any damages suffered, shall be exclusive, final,
and binding on all parties, their heirs, executors, administrators, successors
and assigns.

      9. Confidential Information; Non-Solicitation; Non-Competition. (a) The
Executive shall hold in a fiduciary capacity for the benefit of the Company all
secret, proprietary, or confidential materials, knowledge, data or any other
information relating to the Company or any of its affiliated companies, and
their respective businesses ("Confidential Information"), which shall have been
obtained by the Executive during the Executive's employment by the Company or
any of its affiliated companies and that shall not have been or now or
hereafter have become public knowledge (other than by acts by the Executive or
representatives of the Executive in violation of this Agreement). During the
Employment Period and (a) for a period of five years thereafter with respect to
Confidential Information that does not include trade secrets, and (b) any time
thereafter with respect to Confidential Information that does include trade
secrets, the Executive shall not, without the prior written consent of the
Company or as may otherwise be



                                     -11-
<PAGE>   12



required by law or legal process, communicate or divulge any such information,
knowledge or data to anyone other than the Company and those designated by it.

            (b) In addition, the Executive shall not, at any time during the
Employment Period and for any period thereafter with respect to which the
Executive is in receipt of a severance benefit under this Agreement (by way of
illustration, if the Executive terminates his employment for Good Reason, for a
period of three years), (i) engage or become interested as an owner (other than
as an owner of less than 5% of the stock of a publicly owned company),
stockholder, partner, director, officer, employee (in an executive capacity),
consultant or otherwise in any business that is competitive with any business
conducted by the Company or any of its affiliated companies during the
Employment Period or as of the Date of Termination, as applicable or (ii)
recruit, solicit for employment, hire or engage any employee or individual
consultant of the Company or any person who was an employee or individual
consultant of the Company within two (2) years prior to the Date of Termination.
The Executive acknowledges that these provisions are necessary for the Company's
protection and are not unreasonable, since he would be able to obtain employment
with companies whose businesses are not competitive with those of the Company
and its affiliated companies and would be able to recruit and hire personnel
other than employees of the Company. The duration and the scope of these
restrictions on the Executive's activities are divisible, so that if any
provision of this paragraph is held or deemed to be invalid, that provision
shall be automatically modified to the extent necessary to make it valid.

            The Executive acknowledges that a violation or attempted violation
on the Executive's part of this Section 9 will cause irreparable damage to the
Company, and the Executive therefore agrees that the Company shall be entitled
as a matter of right to an injunction, out of any court of competent
jurisdiction, restraining any violation or further violation of such promises by
the Executive or the Executive's employees, partners or agents. The Executive
agrees that such right to an injunction is cumulative and in addition to
whatever other remedies the Company may have under law or equity.

      10.   Successors.

      (a) This Agreement is personal to the Executive and without the prior
written consent of the Company shall not be assignable by the Executive
otherwise than by will or the laws of descent and distribution.

      (b) This Agreement shall inure to the benefit of and be enforceable by the
Executive's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. If the Executive should
die while any amount would still be payable hereunder if the Executive had
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to the Executive's devisee,
legatee or other designee or, if there is no such designee, to the Executive's
estate.



                                     -12-
<PAGE>   13



      (c) The Company shall require any successor (whether direct or indirect,
by purchase, merger, consolidation or otherwise) to all or substantially all of
the business and/or assets of the Company to expressly assume and agree to
perform this Agreement in the same manner and to the same extent that the
Company would be required to perform it if no such succession had taken place.
As used in this Agreement, "Company" shall mean the Company as defined above and
any successor to its business and/or assets that assumes and agrees to perform
this Agreement by operation of law, or otherwise. Prior to a Change in Control,
the term "Company" shall also mean any affiliate of the Company to which the
Executive may be transferred and the Company shall cause such successor employer
to be considered the "Company" and to be bound by the terms of this Agreement
and this Agreement shall be amended to so provide. Following a Change in
Control, the term "Company" shall not mean any affiliate of the Company to which
Executive may be transferred unless the Executive shall have previously approved
of such transfer in writing, in which case the Company shall cause such
successor employer to be considered the "Company" and to be bound by the terms
of this Agreement and this Agreement shall be amended to so provide. Failure of
the Company to obtain an assumption and agreement as described in this Section
10(c) prior to the effective date of a succession shall be a breach of this
Agreement and shall entitle the Executive to compensation from the Company in
the same amount and on the same terms as the Executive would be entitled to
under this Agreement if the Executive were to terminate the Executive's
employment for Good Reason, except that, for purposes of implementing the
foregoing, the date on which any such succession becomes effective shall be
deemed the Date of Termination.

      11.   Miscellaneous.

      (a) This Agreement shall be governed by and construed in accordance with
the laws of the State of Delaware, without reference to the conflict of laws
provisions thereof. The captions of this Agreement are not part of the
provisions hereof and shall have no force or effect. No provision of this
Agreement may be modified, waived or discharged unless such waiver, modification
or discharge is agreed to in writing and signed by the Executive and such
officer as may be specifically designated by the Board. No waiver by either
party hereto at any time of any breach by the other party hereto of, or
compliance with, any condition or provision of this Agreement to be performed by
such other party shall be deemed a waiver of similar or dissimilar provisions or
conditions at the same or at any prior or subsequent time. No agreements or
representations, oral or otherwise, express or implied, with respect to the
subject matter hereof have been made by either party which are not expressly set
forth in this Agreement.

      (b) All notices and other communications hereunder shall be in writing and
shall be given by hand delivery to the other party or by registered or certified
mail, return-receipt requested, postage prepaid, addressed as follows:

Mr. Kelley:

LETTER SUPPLEMENT TO CONTRACT NO. DE-AC05-760R01312

This letter supplement will confirm the understanding reached between
Electric Energy, Inc. (Company) and the United States Department of Energy
(DOE) with respect to amending Power Agreement No. DE-AC05-760R01312
(Agreement) to reduce the DOE Minimum Power Requirement (as that term is
defined in the Agreement) and to compensate Company for the modification and
installation of certain transmission facilities necessitated by that
reduction.

Accordingly, the Agreement is modified as follows:

1.    In Article II, Section 2.08, delete the following sentence:

            DOE's Minimum Power Requirement shall be defined as
            450 MW during the months of March through October and
            550 MW during the months of  November through
            February.

      and substitute the following therefor:

            DOE's Minimum Power Requirement shall be defined as
            150 MW plus the amount required by the Mid-America
            Interconnected Network (MAIN), as Company's daily
            operating reserves, under MAIN Guide 5A.

2.    In Article I,  add the following section:


            SECTION 1.08.  Transmission Improvements.  Subject to
            Section 4.03 below, DOE shall pay Company $2,000,000
            in calendar years 1999, 2000, and 2001, $3,000,000 in
            2002, and $3,500,000 in 2003


<PAGE>   2


            as compensation for modifications to Company's transmission lines
            and transformers and the installation of additional facilities to
            facilitate the transmission of power generated by the Joppa Plant
            to the Sponsoring Companies reliably in light of the reduction in
            DOE's Minimum Power Requirement.

3.    In Article IV, add the following sections:

            SECTION 4.03  Bills for Transmission Improvements.
            Company shall bill DOE for its Transmission
            Improvements obligations as described in Section
            1.08.  The annual amounts shall be billed in thirds,
            with one-third billed in June of each year, one-third
            in July, and one-third in August as follows:

             -------------------------------------------------------
             </TABLE>

            The total billing amount over the five-year period
            shall not exceed the reasonable and necessary
            expenses actually incurred by Company under Section
            1.08 (including an allowance for funds used during
            construction) or $12,500,000, whichever is less.  In
            the event the total cost is less than $12,500,000,
            the final billing or billings will be reduced to
            reflect such lower cost. DOE shall be entitled to
            audit the cost of transmission improvements in
            accordance with Sections 7.02 and 7.03 below.

            SECTION 4.04  Summary and Forecast of Transmission
            Improvement Costs  On or about December 31, 1999, and
            each December 31 thereafter, Company shall provide
            DOE with a report setting forth all transmission
            improvement costs (a) incurred during the preceding
            calendar year and (b) forecast for the succeeding two
            calendar years; provided, however, that Company need
            not submit any such reports once it has reported
            having incurred more than $12,500,000 in transmission
            improvement costs.

Dear Mr. Draper:

LETTER SUPPLEMENT TO CONTRACT NO. DE-AC05-76OR01530

This letter supplement will confirm the understanding reached
between Ohio Valley Electric Corporation (OVEC) and the United
States Department of Energy (DOE) with respect to Power Agreement
No. DE-AC05-76OR01530 (Agreement) to reduce the DOE Contract Demand
(as that term is defined in the Agreement) and obtain reasonably
priced power for the OVEC Sponsoring Companies and the Paducah
Uranium Enrichment Plant during the summer of 1999.

We understand from our discussions with representatives of OVEC
that the OVEC Sponsoring Companies would be able to utilize the
capacity, and the energy related thereto, which DOE offers to
release during the periods set forth in Schedule A below.
Accordingly, we understand that OVEC, with the concurrence of its
Sponsoring Companies, is willing to agree pursuant to Paragraph 1
of Section 2.05 and Section 7.11 of the Agreement to waive for such
periods any requirement that the DOE contract demand during such
period be higher than the following stated Net Demand for each
referenced period:

Furthermore, we understand that OVEC, with the concurrence of its
Sponsoring Companies, is willing pursuant to Section 7.11 to waive
partially (i) the requirements under Section 3.06 and 3.07 of the
Agreement that DOE pay 100 percent of the costs of Additional
Facilities and Replacements (AFR) and (ii) if appropriate, the
requirements under Sections 3.04.4 and 3.04.5 of the Agreement that
the adjustments of demand charges shall be made on the basis that
the average DOE capacity in effect equaled unity as to amounts, if
any, specified in Section 3.04.3 with respect to the costs of AFR.



<PAGE>   3
Mr. E. Linn Draper, Jr.           -3-                  March 31, 1999


We further understand that OVEC, with the concurrence of its
Sponsoring Companies, agrees to take further action pursuant to
Paragraph 1 of Section 2.05 of the Agreement to waive any
requirement which would preclude a further reduction of the monthly
DOE contract demand below the Net Demand levels set forth in
Schedule A, in amounts to be determined by DOE in its sole
discretion for the months of June through September 1999.  This
would be designed to assist DOE in its goal to obtain reasonably
priced power for the Paducah Uranium Enrichment Plant during the
summer of 1999, since the transmission required to transfer OVEC
power to Paducah on a firm basis may not be available, and the
credit to DOE's power bill for such released power will make
available the funds necessary to purchase power at locations closer
to the Paducah plant.

Furthermore, we understand that if transmission capacity can be
secured and DOE gives two business days' notice to OVEC that DOE
wishes to transfer to its Paducah facility for any month from June
through August 1999 up to 200 MW of the OVEC power and energy
remaining after the previously referenced reductions of the
contract demand, OVEC is willing to waive its right, under
Paragraph 3 of Section 2.05 of the Agreement, to dispose of such
power and energy.  DOE will reimburse OVEC pursuant to such
paragraph for any transmission charges incurred by OVEC in
connection with such transfer. Such transmission charges shall be
in accordance with the applicable tariffs or other authority of the
transmission providers.

Accordingly, DOE and OVEC agree as follows:

      (a)   The contract demand under the Agreement for the
            purposes of Clause (A) of Paragraph 1 of Section 2.05
            thereunder shall be deemed to equal the reduced amounts
            set forth in Schedule A for the periods referenced
            therein except to the extent that DOE exercises its
            right under paragraph (c) below to reduce further the
            DOE contract demand;


      (b)   DOE will be relieved of twenty-eight percent (28%) of
            the AFR costs incurred by OVEC from May 1, 1999,
            through October 31, 1999 as well as the gross-up to
            cover estimated income taxes, if any, associated with
            that amount, provided, that DOE will continue to pay
            amounts due each year to a trustee for purchasers of
            OVEC notes pursuant to assignments, consents to
            assignment and notices of assignment dated on or about
            June 9, 1993, related to the financing of


<PAGE>   4

Mr. E. Linn Draper, Jr.           -4-                  March 31, 1999

            the Clifty Creek Coal Switch Project. DOE will be entitled to
            audit such AFR costs in accordance with Section 7.04 of the
            Agreement;

      (c)   The monthly DOE contract demand under the Agreement may
            be reduced below the levels set forth in Schedule A in
            amounts to be determined by DOE in its sole discretion
            for the months of June through September 1999,
            provided, that on or before two business days after the
            execution of this Letter Supplement by both parties
            (the "Exercise Date") DOE shall exercise its one-time
            option by notifying OVEC and each Sponsor, by facsimile
            on or before 4:00 p.m. E.S.T., of all monthly (June
            through September 1999) optional contract demand
            reductions;



      (d)   OVEC will credit DOE's power bills in an amount equal
            to the DOE contract demand reduction below the levels
            set forth in Schedule A (above) for each of the months
            of June through September 1999 times 80 percent of the
            NYMEX monthly into Cinergy, firm, futures on-peak (5 x
            16) for such month determined as of market closing on
            March 5, 1999 times the number of on-peak hours during
            such month, minus (a) the demand charges which DOE
            avoids by reason of such monthly reductions in contract
            demand and (b) charges for energy in amounts equal to
            the reductions in contract demand times the number of
            on-peak hours during such month times OVEC's energy rate
            per MWH.  The above-referenced March 5, 1999 NYMEX
            closing prices were $59.25/MWH for June 1999; $120/MWH
            for July 1999; $113/MWH for August 1999 and $36.50/MWH
            for September 1999.  No later than April 1, 1999, OVEC
            will issue a credit memorandum to DOE setting forth the
            estimated total credits due DOE under this paragraph.
            Such credit memorandum will indicate that the credits
            are subject to receipt of all required governmental
            approvals in form and substance satisfactory to OVEC.
            Such credits will be deducted from bills rendered by
            OVEC to DOE after receipt of all such governmental
            approvals pursuant to the following schedule:  July -
            $10,000,000; August - $10,000,000; September -
            remaining balance.  In the event that governmental
            approvals are delayed beyond July 1999, the credits
            previously due pursuant to the above schedule will
            become immediately effective upon the receipt of the
            last of such approvals. Any credit amounts in excess of
            any monthly bill shall be applied to


<PAGE>   5

Mr. E. Linn Draper, Jr.           -5-                  March 31, 1999

            the following monthly bill. Monthly true-ups of any estimates will
            also be reflected in such bills.

      (e)   The Parties acknowledge that the credits to DOE's power
            bills pursuant to paragraph (d) are subject to approval
            by the Public Utilities Commission of Ohio.  Likewise,
            such credits are subject to execution by the Sponsoring
            Companies, and regulatory approval, of an amendment to
            the Inter-Company Power Agreement in form and substance
            satisfactory to OVEC providing for payments to OVEC by
            the Sponsoring Companies sufficient to reimburse OVEC
            for the credits to the DOE power bills.  The parties
            further acknowledge that the credits to DOE's power
            bills are subject to acceptance by the Federal Energy
            Regulatory Commission and approval by the Virginia
            State Corporation Commission of such amendment to the
            Inter-Company Power Agreement.  OVEC will use its best
            efforts to obtain all required regulatory approvals,
            including those referenced herein, as expeditiously as
            possible, and request  such approvals to be
            effective April 1, 1999.

      (f)   In addition, if transmission capacity can be secured
            and DOE gives two business days' notice to OVEC that
            DOE wishes to transfer for any month from June through
            August 1999 up to 200 MW of the remaining OVEC power
            and energy to its Paducah facility, OVEC will waive its
            right, under Paragraph 3 of Section 2.05 of the
            Agreement, to dispose of such power and energy.  DOE
            will reimburse OVEC pursuant to such paragraph for any
            transmission charges incurred by OVEC in connection
            with such transfer. Such transmission charges shall be
            in accordance with the applicable tariffs or other
            authority of the transmission providers.

      (g)   Neither DOE nor OVEC will assert that a failure by any
            other Party to enforce rights it may have under the
            OVEC/DOE Power Agreement or the Inter-Company Power
            Agreement constitutes, nor shall such failure to
            enforce such rights constitute, a waiver or
            relinquishment, explicit or implicit, of any provision
            of either agreement.


If OVEC agrees to the matters described above, please execute a
copy of this letter at the place designated for your signature.

      automatically converted into a Base Rate Loan in the same amount.

            2.2 Base Rate Loans. Each request by Borrower for a Base Rate Loan
shall be made pursuant to a Request for Loan received by the Administrative
Agent, at the Administrative Agent's Office, not later than 11:00 a.m.
California time, on the date (which must be a Banking Day) immediately prior to
the date of the requested Base Rate Loan (except in the case of Base Rate Loans

      the Lenders by telecopier.

                  (c) Unless the Administrative Agent and the Requisite Lenders

            2.5   [Intentionally Omitted].

Borrower to the Administrative Agent, voluntarily to reduce, permanently and
irrevocably, in aggregate principal amounts in an integral multiple of
$1,000,000 but not less than $5,000,000, or to terminate, all or a portion of
the then undisbursed portion of the Commitment. The Administrative Agent shall
promptly notify the Lenders of any reduction or termination of the Commitment
under this Section.

            2.7   [Intentionally Omitted].

            2.8 Optional Termination of Commitment. Following the occurrence of

written notice to the Administrative Agent of such occurrence or (ii) if no such
notice has been received by the Administrative Agent, the date upon which the
Administrative Agent has actual knowledge thereof, to terminate the Commitment,
in which case the Commitment shall be terminated, and all outstanding Loans
shall be repaid, effective on the date which is thirty (30) days subsequent to
written notice from the Administrative Agent to Borrower thereof.

            2.9 Administrative Agent's Right to Assume Funds Available for
Advances. Unless the Administrative Agent shall have been notified by any Lender
no later than 10:00 a.m. on the Banking Day of the proposed funding by the
Administrative Agent of any Loan that such Lender does not intend to make
available to the Administrative Agent such Lender's portion of the total amount

Administrative Agent









                                   -28-

corresponding amount. If the Administrative Agent has made funds available to
Borrower based on such assumption and such corresponding amount is not in fact
made available to the Administrative Agent by such Lender, the Administrative
Agent shall be entitled to recover such corresponding amount on demand from such
Lender. If such Lender does not pay such corresponding amount forthwith upon the
Administrative Agent's demand therefor, the Administrative Agent promptly shall
notify Borrower and Borrower shall pay such corresponding amount to the
Administrative Agent. The Administrative Agent also shall be entitled to recover
from such Lender interest on such correspond ing amount in respect of each day
from the date such corresponding amount was made available by the Administrative
Agent to Borrower to the date such corresponding amount is recovered by the
Administrative Agent, at a rate per annum equal to the daily Federal Funds Rate.
Nothing herein shall be deemed to relieve any Lender from its obligation to
fulfill its share of the Commitment or to prejudice any rights which the
Administrative Agent or Borrower may have against any Lender as a result of any
default by such Lender hereunder.

            2.10 Guaranty. The Obligations shall be guaranteed by the Subsidiary
Guarantors pursuant to the Subsidiary Guaranty.

or directive regarding capital adequacy (whether or not having the force of Law)
of any such central bank or other authority not imposed as a result of such
Lender's or such corporation's failure to comply with any other Laws, affects or

Lender, from time to time as specified in good faith by such Lender, additional

      Borrower shall not be obligated to pay any such amount which arose prior
      to the date which is ninety (90) days preceding the date of such demand or
      is attributable to periods prior to the date which is ninety (90) days
      preceding the date of such demand). The Lender's determination of such
      amount shall be conclusive in the absence of manifest error.

      any Special Eurodollar Circumstance:

                        (1) shall subject any Lender or its Eurodollar Lending
            Office to any tax, duty or other charge or cost with respect to any
            Eurodollar Rate Advance, any of its Notes evidencing Eurodollar Rate
            Loans or its obligation to make Eurodollar Rate Advances, or shall
            change the basis of taxation of payments to any Lender attributable
            to the principal of or interest on any Eurodollar Rate Advance or
            any other amounts due under this Agreement in respect of any
            Eurodollar Rate Advance, any of its Notes evidencing Eurodollar Rate
            Loans or its obligation to make Eurodollar Rate Advances, excluding
            (i) taxes imposed on or measured in whole or in part by its overall
            net income by (A) any jurisdiction (or political subdivision
            thereof) in which it is orga nized or maintains its principal office
            or Eurodollar Lending Office or (B) any jurisdiction (or political
            subdivision thereof) in which it is "doing business" and (ii) any
            withholding taxes or other taxes based on gross income imposed by
            the United States of America for any period with respect to which it
            has failed to provide Borrower with the appropriate

            are then required by applicable Laws;

                        (2) shall impose, modify or deem applicable any reserve
            not applicable or deemed applicable on the date hereof (including
            any reserve imposed by the Board of Governors of the Federal Reserve
            System, special deposit, capital or similar requirements against
            assets of, deposits with or for the account of, or credit extended
            by, any Lender or its Eurodollar Lending Office); or

                        (3) shall impose on any Lender or its Eurodollar Lending
            Office or the Designated Eurodollar Market any other condition
            affecting any Eurodollar Rate Advance, any of its Notes evidencing
            Eurodollar Rate Loans, its obligation to make Eurodollar Rate
            Advances or this Agreement, or shall otherwise affect any of the
            same;

      and the result of any of the foregoing, as determined in good faith by
      such Lender, increases the cost to such Lender or its Eurodollar Lending
      Office of making or maintaining any Eurodollar Rate Advance or in respect
      of any Eurodollar Rate Advance, any of its Notes evidencing Eurodollar
      Rate Loans or its obligation to make Eurodollar Rate Advances or reduces
      the amount of any sum received or receivable by such Lender or its
      Eurodollar Lending Office with respect to any Eurodollar Rate Advance, any
      of its Notes evidencing Eurodollar Rate Loans or its obligation to make
      Eurodollar Rate Advances (assuming such Lender's Eurodollar Lending Office
      had funded 100% of its Eurodollar Rate Advance in the Designated
      Eurodollar Market), then, within five (5) Banking Days after demand by
      such Lender (with a copy to the Administrative Agent), Borrower shall pay
      to such Lender such additional amount or amounts as will compensate such
      Lender for such increased cost or reduction (determined as though such
      Lender's Eurodollar Lending Office had funded 100% of its Eurodollar Rate
      Advance in the Designated Eurodollar Market); provided, that Borrower
      shall not be obligated to pay any such amount which arose prior to the
      date which is ninety (90) days preceding the date of such demand or is
      attributable to periods prior to the date which is ninety (90) days
      preceding the date of such demand. A statement of any Lender claiming
      compensation under this subsection shall be conclusive in the absence of
      manifest error.

                  (c) If, after the date hereof, the existence or occurrence of
      any Special Eurodollar Circumstance shall, in the good faith opinion of
      any Lender,









                                      -34-

      make it unlawful or impossible for such Lender or its Eurodollar Lending
      Office to make, maintain or fund its portion of any Eurodollar Rate Loan,
      or materially restrict the authority of such Lender to purchase or sell,
      or to take deposits of, Dollars in the Designated Eurodollar Market, or to
      determine or charge interest rates based upon the Eurodollar Rate, and
      such Lender shall so notify the Administrative Agent, then such Lender's
      obligation to make Eurodollar Rate Advances shall be suspended for the
      duration of such illegality or impossibility and the Administrative Agent
      forthwith shall give notice thereof to the other Lenders and Borrower.
      Upon receipt of such notice, the outstanding principal amount of such
      Lender's Eurodollar Rate Advances, together with accrued interest thereon,
      automatically shall be converted to Base Rate Advances on either (1) the
      last day of the Eurodollar Period(s) applicable to such Eurodollar Rate
      Advances if such Lender may lawfully continue to maintain and fund such
      Eurodollar Rate Advances to such day(s) or (2) immediately if such Lender
      may not lawfully continue to fund and maintain such Eurodollar Rate
      Advances to such day(s), provided that in such event the conversion shall
      not be subject to payment of a prepayment fee under Section 3.8(e). Each
      Lender agrees to endeavor promptly to notify Borrower of any event of
      which it has actual knowledge, occurring after the Closing Date, which
      will cause that Lender to notify the Administrative Agent under this
      Section, and agrees to designate a different Eurodollar Lending Office if
      such designation will avoid the need for such notice and will not, in the
      good faith judgment of such Lender, otherwise be materially
      disadvantageous to such Lender. In the event that any Lender is unable,
      for the reasons set forth above, to make, maintain or fund its portion of
      any Eurodollar Rate Loan, such Lender shall fund such amount as an Base
      Rate Advance for the same period of time, and such amount shall be treated
      in all respects as an Base Rate Advance. Any Lender whose obligation to
      make Eurodollar Rate Advances has been suspended under this Section shall
      promptly notify the Administrative Agent and Borrower of the cessation of
      the Special Eurodollar Circumstance which gave rise to such suspension.

                  (d) If, with respect to any proposed Eurodollar Rate Loan:

                        (1) the Administrative Agent reasonably determines that,
            by reason of circumstances affecting the Designated Eurodollar
            Market generally that are beyond the reasonable control of the
            Lenders, deposits in Dollars (in the applicable amounts) are not
            being offered to any Lender in the Designated Eurodollar Market for
            the applicable Eurodollar Period; or









                                      -35-

<PAGE>   43




                        (2) the Requisite Lenders advise the Administrative
            Agent that the Eurodollar Rate as determined by the Administrative
            Agent (i) does not represent the effective pricing to such Lenders
            for deposits in Dollars in the Designated Eurodollar Market in the
            relevant amount for the applicable Eurodollar Period, or (ii) will
            not adequately and fairly reflect the cost to such Lenders of making
            the applicable Euro dollar Rate Advances;

      then the Administrative Agent forthwith shall give notice thereof to
      Borrower and the Lenders, whereupon until the Administrative Agent
      notifies Borrower that the circumstances giving rise to such suspension no
      longer exist, the obligation of the Lenders to make any future Eurodollar
      Rate Advances shall be suspended.

                  (e) Upon payment or prepayment of any Eurodollar Rate Advance
      (other than as the result of a conversion required under Section 3.8(c) on
      a day other than the last day in the applicable Eurodollar Period (whether
      voluntarily, involuntarily, by reason of acceleration, or otherwise), or
      upon the failure of Borrower (for a reason other than the breach by a
      Lender of its obligation pursuant to Section 2.1(a) to make an Advance) to
      borrow on the date or in the amount specified for a Eurodollar Rate Loan
      in any Request for Loan, Borrower shall pay to the appropriate Lender
      within five (5) Banking Days after demand a prepayment fee or failure to
      borrow fee, as the case may be (determined as though 100% of the
      Eurodollar Rate Advance had been funded in the Designated Eurodollar
      Market) equal to the sum of:

                        (1)   $250; plus

                        (2) the amount, if any, by which (i) the additional
            interest would have accrued on the amount prepaid or not borrowed at
            the Eurodollar Rate plus the Applicable Eurodollar Rate Margin if
            that amount had remained or been outstanding through the last day of
            the applicable Eurodollar Period exceeds (ii) the interest that the
            Lender could recover by placing such amount on deposit in the
            Designated Eurodollar Market for a period beginning on the date of
            the prepayment or failure to borrow and ending on the last day of
            the applicable Eurodollar Period (or, if no deposit rate quotation
            is available for such period, for the most comparable period for
            which a deposit rate quotation may be obtained); plus









                                      -36-

<PAGE>   44




                        (3) all out-of-pocket expenses incurred by the Lender
            reasonably attributable to such payment, prepayment or failure to
            borrow.

      Each Lender's determination of the amount of any prepayment fee payable
      under this Section shall be conclusive in the absence of manifest error.

                  (f) Each Lender agrees to endeavor promptly to notify Borrower
      of any event of which it has actual knowledge, occurring after the Closing
      Date, which will entitle such Lender to compensation pursuant to clause
      (a) or clause (b) of this Section, and agrees to designate a different
      Eurodollar Lending Office if such designation will avoid the need for or
      reduce the amount of such compensation and will not, in the good faith
      judgment of such Lender, otherwise be materially disadvantageous to such
      Lender. Any request for compensation by a Lender under this Section shall
      set forth the basis upon which it has been determined that such an amount
      is due from Borrower, a calculation of the amount due, and a certification
      that the corresponding costs have been incurred by the Lender.

            3.9 Late Payments. If any installment of principal or interest or
any fee or cost or other amount payable under any Loan Document to the
Administrative Agent or any Lender is not paid when due, it shall thereafter
bear interest at a fluctuating interest rate per annum at all times equal to the
sum of the Base Rate plus 2%, to the fullest extent permitted by applicable
Laws. Accrued and unpaid interest on past due amounts (including, without
limitation, interest on past due interest) shall be compounded monthly, on the
last day of each calendar month, to the fullest extent permitted by applicable
Laws.

            3.10 Computation of Interest and Fees. Computation of interest on
Base Rate Loans under this Agreement shall be calculated on the basis of a year
of 365/366 days and the actual number of days elapsed. Computation of interest
on Eurodollar Rate Loans and all fees under this Agreement shall be calculated
on the basis of a year of 360 days and the actual number of days elapsed.
Interest shall accrue on each Loan for the day on which the Loan is made;
interest shall not accrue on a Loan, or any portion thereof, for the day on
which the Loan or such portion is paid. Any Loan that is repaid on the same day
on which it is made shall bear interest for one day. Notwithstanding anything in
this Agreement to the contrary, interest in excess of the maximum amount
permitted by applicable Laws shall not accrue or be payable hereunder or under
the Notes, and any amount paid as interest hereunder or under the









                                      -37-

<PAGE>   45



Notes which would otherwise be in excess of such maximum permitted amount shall
instead be treated as a payment of principal.

            3.11 Non-Banking Days. If any payment to be made by Borrower or any
other Party under any Loan Document shall come due on a day other than a Banking
Day, payment shall instead be considered due on the next succeeding Banking Day
and the extension of time shall be reflected in computing interest and fees.

            3.12  Manner and Treatment of Payments.

                  (a) Each payment hereunder (except payments pursuant to
      Sections 3.7, 3.8, 11.3, 11.11 and 11.22) or on the Notes or under any
      other Loan Document shall be made by Borrower to the Administrative Agent
      without setoff, deduction or counterclaim at the Administrative Agent's
      Office for the account of each of the Lenders or the Administrative Agent,
      as the case may be, in immediately available funds not later than 11:00
      a.m. California time, on the day of payment (which must be a Banking Day).
      All payments received after such time, on any Banking Day, shall be deemed
      received on the next succeeding Banking Day. The amount of all payments
      received by the Administrative Agent for the account of each Lender shall
      be immediately paid by the Administrative Agent to the applicable Lender
      in immediately available funds and, if such payment was received by the
      Administrative Agent by 11:00 a.m., California time, on a Banking Day and
      not so made available to the account of a Lender on that Banking Day, the
      Administrative Agent shall reimburse that Lender for the cost to such
      Lender of funding the amount of such payment at the Federal Funds Rate.
      All payments shall be made in lawful money of the United States of
      America.

                  (b) Each payment or prepayment on account of any Loan shall be
      applied pro rata according to the outstanding Advances made by each Lender
      comprising such Loan.

                  (c) Each Lender shall use its best efforts to keep a record
      (in writing or by an electronic data entry system) of Advances made by it
      and payments received by it with respect to each of its Notes and, subject
      to Section 10.6(g), such record shall, as against Borrower, be presumptive
      evidence of the amounts owing. Notwithstanding the foregoing sentence, the
      failure by any Lender to keep such a record shall not affect Borrower's
      obligation to pay the Obligations.










                                      -38-

<PAGE>   46



                  (d) (i) Any and all payments by Borrower under this Agreement
      shall be made free and clear of and without deduction or withholding for
      any and all present or future taxes, including those taxes described in
      Section 11.3, levies, imposts, deductions, charges or withholdings, and
      all interest, penalties and liabilities with respect thereto, imposed by
      any Governmental Agency, excluding, in the case of each Lender and the
      Administrative Agent, net income taxes or branch profits taxes or
      franchise and excise taxes (to the extent such taxes are imposed in lieu
      of net income taxes), imposed on any Lender or the Administrative Agent as
      a result of a connection between such Lender or the Administrative Agent
      and the jurisdiction of the Governmental Agency imposing such tax (other
      than any such connection arising solely from such Lender or the
      Administrative Agent having executed, delivered or performed its
      obligations or received a payment under, or enforced, this Agreement) (all
      such non-excluded taxes, assessments and charges being hereinafter
      referred to as "Non-Excluded Taxes"). If Borrower shall be required by law
      to deduct or withhold any Non-Excluded Taxes from or in respect of any sum
      payable hereunder to any Lender or the Administrative Agent (A) the amount
      payable shall be increased as may be necessary so that after making all
      required deductions or withholdings (including required deductions or
      withholdings for Non-Excluded Taxes applicable to additional amounts
      payable under this Section 3.12(d)) such Lender or the Administrative
      Agent, as the case may be, receives an amount equal to the amount it would
      have received had no such deductions or withholdings been made, (B)
      Borrower shall make such deductions or withholdings and (C) Borrower shall
      pay the full amount deducted or withheld to the relevant Governmental
      Agency in accordance with applicable Laws.

                        (ii) Each Lender organized under the Laws of the United
      States of America or a State thereof or the District of Columbia on or
      prior to the execution and delivery of this Agreement (A) shall provide
      each of the Administrative Agent and Borrower with two original and duly
      completed United States Internal Revenue Service Forms W-9, or successor
      applicable form, certifying that such Lender is a United States resident
      and is exempt from United States backup withholding tax, (B) shall provide
      the Administrative Agent and Borrower two further copies of any such form
      or certification from time to time thereafter as requested in writing by
      Borrower and (C) shall obtain such extensions and renewals thereof as may
      reasonably be requested in writing by Borrower or the Administrative
      Agent. Each Person that shall become a participant pursuant to Section
      11.8 shall, upon the effectiveness of the related transfer, be required to
      provide all of the forms and certifications required









                                      -39-

<PAGE>   47



      pursuant to this Section 3.12(d)(ii) as appropriate, as if such
      participant were a Lender; provided that such participant shall furnish
      all such required forms and certifications to the Lender from which the
      related participation was purchased.

                        (iii) Notwithstanding anything else in this Agreement to
      the contrary, for any period with respect to which a Lender has failed to
      comply with the requirements of Section 3.12(d)(ii) or Section 11.21, as
      the case may be, such Lender shall not be entitled to any payment under
      this Section 3.12(d) or to indemnification under Section 3.12(e) with
      respect to Non-Excluded Taxes imposed by reason of such failure; provided,
      however, that should a Lender become subject to Non-Excluded Taxes because
      of its failure to deliver a form required hereunder, Borrower shall, at
      such Lender's expense (including internal costs of Borrower), take such
      steps as such Lender shall reasonably require to assist the Lender to
      recover such Non-Excluded Taxes.

                        (iv) Should any Lender claim a refund, credit or
      deduction from a Governmental Agency to which such Lender would not be
      entitled but for the payment by Borrower of Non-Excluded Taxes as required
      by this Section 3.12(d), such Lender thereupon shall pay the amount of
      such refund or, in the case of a credit or deduction, the amount equal to
      the amount by which other taxes of such Lender are actually reduced,
      together with any interest paid or allowed by the refunding, crediting or
      deducting Governmental Agency in connection with such refund, credit or
      deduction.

                  (e) Borrower shall indemnify each Lender and the Agent for and
      hold each of them harmless against the full amount of Non-Excluded Taxes
      (including Non-Excluded Taxes of any kind imposed by a Governmental Agency
      on additional amounts required to be paid pursuant to Section 3.12(d))
      imposed on or paid by such Lender or the Administrative Agent, as the case
      may be. Each Lender and the Administrative Agent hereby agrees to give
      written notice to Borrower, as appropriate, of the assertion of any claim
      against such Lender or the Agent relating to Non-Excluded Taxes as
      promptly as practicable after such Lender or the Administrative Agent has
      been notified in writing of such assertion. This indemnification shall be
      made within 30 days from the date such Lender or the Administrative Agent,
      as the case may be, provides Borrower, as appropriate, with such written
      notice.

            3.13  Funding Sources.  Nothing in this Agreement shall be deemed to
obligate any Lender to obtain the funds for any Loan or Advance in any
particular









                                      -40-

<PAGE>   48



place or manner or to constitute a representation by any Lender that it has
obtained or will obtain the funds for any Loan or Advance in any particular
place or manner.

            3.14 Failure to Charge Not Subsequent Waiver. Any decision by the
Administrative Agent or any Lender not to require payment of any interest
(including interest arising under Section 3.9), fee, cost or other amount
payable under any Loan Document, or to calculate any amount payable by a
particular method, on any occasion shall in no way limit or be deemed a waiver
of the Administrative Agent's or such Lender's right to require full payment of
any interest (including interest arising under Section 3.9), fee, cost or other
amount payable under any Loan Document, or to calculate an amount payable by
another method that is not inconsistent with this Agreement, on any other or
subsequent occasion.

            3.15 Administrative Agent's Right to Assume Payments Will be Made.
Unless the Administrative Agent shall have been notified by Borrower prior to
the date on which any payment to be made by Borrower hereunder is due that
Borrower does not intend to remit such payment, the Administrative Agent may, in
its discretion, assume that Borrower has remitted such payment when so due and
the Administrative Agent may, in its discretion and in reliance upon such
assumption, make available to each Lender on such payment date an amount equal
to such Lender's share of such assumed payment. If Borrower has not in fact
remitted such payment to the Administrative Agent, each Lender shall forthwith
on demand repay to the Administrative Agent the amount of such assumed payment
made available to such Lender, together with interest thereon in respect of each
day from and including the date such amount was made available by the
Administrative Agent to such Lender to the date such amount is repaid to the
Administrative Agent at the Federal Funds Rate.

            3.16 Fee Determination Detail. The Administrative Agent, and any
Lender, shall provide reasonable detail to Borrower regarding the manner in
which the amount of any payment to the Administrative Agent and the Lenders, or
that Lender, under Article 3 has been determined, concurrently with demand for
such payment.

            3.17 Survivability. All of Borrower's obligations under Sections 3.7
and 3.8 shall survive for the ninety (90) day period following the date on which
the Commitment is terminated and all Loans hereunder are fully paid, and
Borrower shall remain obligated thereunder for all claims under such Sections
made by any Lender to Borrower prior to the expiration of such period.

            3.18 Substitution of Lender. If (a) the obligation of any Lender to
make Eurodollar Rate Advances has been suspended for ten (10) Banking Days or









                                      -41-

<PAGE>   49



more pursuant to Sections 3.8(c) or 3.8(d) or (b) any Lender has demanded and
been paid compensation of $5,000 or more under Section 3.7 or 3.8, Borrower
shall have the right, with the assistance of the Administrative Agent, to seek a
mutually satisfactory substitute lender or lenders (which may be one or more of
the Lenders or an Eligible Assignee) to replace such Lender. Any substitution
under this Section 3.18 may be accomplished at Borrower's option either (i) by
the replaced Lender assigning its rights and obligations hereunder to the
replacement lender or lenders pursuant to Section 11.8 at a mutually agreeable
price or (ii) by Borrower prepaying all outstanding Advances from the replaced
Lender and terminating its obligations hereunder on a date specified in a notice
delivered to the Administrative Agent and the replaced Lender at least three (3)
Banking Days before the date so specified (and compensating such Lender for any
resulting funding losses as provided in Section 3.8(e) and concurrently the
replacement lender or lenders assuming a Pro Rata Share of the Commitment in an
amount equal to the Pro Rata Share of the Commitment being terminated and making
Advances in the same aggregate amount and having the same maturity date or
dates, respectively, as the Advances being prepaid, all pursuant to documents
reasonably satisfactory to the Administrative Agent (and in the case of any
document to be signed by the replaced Lender, reasonably satisfactory to such
Lender). Borrower must give written notice to the affected Lender and the
Administrative Agent within sixty (60) days after the applicable event described
in clauses (a) or (b) of the first sentence of this Section of its intent to
exercise its rights under this Section, and must complete the substitution
within thirty (30) days after the date of such notice. No such substitution
shall relieve Borrower of its obligations to compensate and/or indemnify the
replaced Lender as required by Sections 3.7 and 3.8 with respect to the period
before it is replaced and to pay all accrued interest, accrued fees and other
amounts owing the replaced Lender hereunder.

                                  Article 4
                       REPRESENTATIONS AND WARRANTIES


            Borrower represents and warrants to the Lenders that:

            4.1 Existence and Qualification; Power; Compliance With Laws.
Borrower is a corporation duly formed, validly existing and in good standing
under the Laws of Delaware. Borrower is duly qualified or registered to transact
business and is in good standing in Maryland and each other jurisdiction in
which the conduct of its business or the ownership or leasing of its Properties
makes such qualification or registration necessary, except where the failure so
to qualify or register and to be in good standing would not constitute a
Material Adverse Effect. Borrower has all requisite power and authority to
conduct its business, to own and lease its Properties and to execute and deliver
each Loan Document to which it is a Party and to perform its Obligations. All
outstanding shares of capital stock of Borrower are duly authorized, validly
issued, fully paid and non-assessable, and no holder thereof has any enforceable
right of rescission under any applicable state or federal securities Laws.
Borrower is in compliance with all Laws (except for Hazardous Materials Laws
which are the subject of Section 4.18) and other legal requirements applicable
to its business, has obtained all authorizations, consents, approvals, orders,
licenses and permits from, and has accomplished all filings, registrations and
qualifications with, or obtained exemptions from any of the foregoing from, any
Governmental Agency that are necessary for the transaction of its business,
except where the failure so to comply, obtain authorizations, etc., file,
register, qualify or obtain exemptions does not constitute a Material Adverse
Effect.

            4.2 Authority; Compliance With Other Agreements and Instruments and
Government Regulations. The execution, delivery and performance by Borrower and
the Subsidiary Guarantors of the Loan Documents to which it is a Party have been
duly authorized by all necessary corporate action, and do not and will not:

                  (a) Require any consent or approval not heretofore obtained of
      any partner, director, stockholder, security holder or creditor of such
      Party;

                  (b) Violate or conflict with any provision of such Party's

      material indenture or loan or credit agreement or any other Contractual
      Obligation to which such Party is a party or by which such Party or any of
      its Property is bound or affected;

and such Party is not in violation of, or default under, any Requirement of Law
or Contractual Obligation, or any material indenture, loan or credit agreement
described in Section 4.2(e), in any respect that constitutes a Material Adverse
Effect.

            4.3 No Governmental Approvals Required. Except as previously
obtained or made, no authorization, consent, approval, order, license or permit
from, or filing, registration or qualification with, any Governmental Agency is
or will be required to authorize or permit under applicable Laws the execution,

Documents to which it is a Party.

            4.4   Subsidiaries.

                  (a) Schedule 4.4 hereto correctly sets forth as of the Closing
      Date the names, form of legal entity, number of shares of capital stock
      issued and outstanding, number of shares owned by Borrower or a Subsidiary
      of Borrower (specifying such owner) and jurisdictions of organization of
      all Subsidiaries of Borrower and specifies which thereof, as of the
      Closing Date, are Inactive Subsidiaries. Except as described in Schedule
      4.4, Borrower does not as of the Closing Date own any capital stock,
      equity interest or debt security which is convertible, or exchangeable,
      for capital stock or equity interest in any Person. Unless otherwise
      indicated in Schedule 4.4, all of the outstanding shares of capital stock,
      or all of the units of equity interest, as the case may be, of each
      Subsidiary are owned of record and beneficially by Borrower, there are no
      outstanding options, warrants or other rights to purchase capital stock of
      any such Subsidiary, and all such shares or equity interests so owned are
      duly authorized, validly issued, fully paid and non-assessable, and were
      issued in compliance with all applicable state and federal securities and
      other Laws, and are free and clear of all Liens, except for Permitted
      Encumbrances.

                  (b) Each Subsidiary is a legal entity of the type described in
      Schedule 4.4 duly formed, validly existing and in good standing under the
      Laws of its jurisdiction of organization, is duly qualified to do business
      as a foreign organization and is in good standing as such in each
      jurisdiction in which the conduct of its business or the ownership or
      leasing of its Properties makes such qualification necessary (except where
      the failure to be so duly qualified and in good standing does not
      constitute a Material Adverse Effect), and has all requisite power and
      authority to conduct its business and to own and lease its Properties.

                  (c) Except as described in Schedule 4.4(c), each Subsidiary is
      in compliance with all Laws (except for Hazardous Materials Laws which are
      the subject of Section 4.18) and other requirements applicable to its
      business and has obtained all authorizations, consents, approvals, orders,
      licenses, and permits from, and each such Subsidiary has accomplished all
      filings, registrations, and qualifications with, or obtained exemptions
      from any of the foregoing from, any Governmental Agency that are necessary
      for the transaction of its business, except where the failure to be in
      such compliance, obtain such authorizations, consents, approvals, orders,
      licenses, and permits, accomplish such filings, registrations, and
      qualifications, or obtain such exemptions, does not constitute a Material
      Adverse Effect.

            4.5 Financial Statements. Borrower has furnished to the Lenders (a)
the audited financial statements of Predecessor for the Fiscal Year ended June
30, 1998, (b) the audited pro-forma financial statements of Borrower for the
Fiscal Year ended June 30, 1998 and (c) the unaudited balance sheet and
statement of operations of Borrower for the Fiscal Quarter ended March 31, 1999.
The financial statements described in clause (a) fairly present in all material
respects the financial condition, results of operations and changes in financial
position of Predecessor, the pro-forma financial statements of Borrower
described in clause (b) fairly present in all material regards the pro-forma (in
accordance with the assumptions included in the notes to such financial
statements) financial condition, results of operations and changes in financial
position of Borrower and the balance sheet and statement of operations described
in clause (c) fairly present the financial condition and results of operations
of Borrower as of such dates and for such periods in conformity with GAAP
consistently applied (except as otherwise indicated in the notes thereto),
subject only to normal year-end accruals and audit adjustments.

            4.6 No Other Liabilities; No Material Adverse Changes. Borrower and
its Subsidiaries do not have any material liability or material contingent
liability required under GAAP to be reflected or disclosed, and not reflected or
disclosed, in the balance sheet described in Section 4.5(c), other than
liabilities and contingent liabilities arising in the ordinary course of
business since the date of such financial statements. As of the Closing Date, no
circumstance or event has occurred that constitutes a Material Adverse Effect
since March 31, 1999.

            4.7 Title to and Location of Property. Borrower and its Subsidiaries
have valid title to the Property (other than assets which are the subject of a
Capital Lease Obligation) reflected in the balance sheet described in Section
4.5(c), other than (a) items of Property or exceptions to title which are in
each case immaterial and Property subsequently sold or disposed of in the
ordinary course of business and (b) uranium inventory owned by customers of
Borrower or its Subsidiaries for which a corresponding liability in favor of
such customers is reflected in such balance sheet. Such Property is free and
clear of all Liens and Rights of Others, other than Liens or Rights of Others
described in Schedule 4.7 and Permitted Encumbrances and Permitted Rights of
Others.

            4.8 Intellectual Property. Except as set forth in Schedule 4.8,
Borrower and its Subsidiaries own, or possess the right to use to the extent
necessary in their respective businesses, all trademarks, service marks, trade
names, copyrights, patents, patent rights and related registrations and
applications that are used in and are material to the conduct of their
businesses as now operated, and no such intellectual property, to the best
knowledge of Borrower, conflicts with the valid trademark, service mark, trade
name, copyright, patent or patent right of any other Person to the extent that
such conflict constitutes a Material Adverse Effect.

            4.9 Public Utility Holding Company Act. Neither Borrower nor any of
its Subsidiaries is a "holding company", or a "subsidiary company" of a "holding
company", or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company", within the meaning of the Public Utility Holding Company
Act of 1935, as amended.

            4.10 Litigation. Except for (a) any matter fully covered as to

insurance for which the insurance carrier has not asserted lack of subject
matter coverage or reserved its right to do so, (b) any matter, or series of
related matters, involving a claim against Borrower or any of its Subsidiaries
or Predecessor of less than $1,000,000, (c) matters involving a claim against
Predecessor for which neither Borrower nor any of its






                                      -46-

Subsidiaries will be liable subsequent to Privatization, (d) matters of an
administrative nature not involving a claim or charge against Borrower or any of
its Subsidiaries or Predecessor, (e) matters involving a claim under Hazardous
Materials Laws which are the subject of Section 4.18 and (f) matters set forth
in Schedule 4.10, there are no actions, suits, proceedings or investigations
pending as to which Borrower or any of its Subsidiaries or Predecessor have been
served or have received notice or, to the best knowledge of Borrower, threatened
against or affecting Borrower or any of its Subsidiaries or Predecessor or any
Property of any of them before any Governmental Agency.

            4.11 Binding Obligations. Each of the Loan Documents to which
Borrower and any Subsidiary Guarantor is a Party will, when executed and
delivered by such Party, constitute the legal, valid and binding obligation of
such Party, enforceable against such Party in accordance with its terms, except
as enforcement may be limited by Debtor Relief Laws or equitable principles
relating to the granting of specific performance and other equitable remedies as
a matter of judicial discretion.

            4.12  No Default.  No event has occurred and is continuing that is a
Default or Event of Default.

                  (a)   With respect to each Pension Plan:

                        (i) such Pension Plan complies in all material respects
            with ERISA and any other applicable Laws to the extent that
            noncompliance could reasonably be expected to have a Material
            Adverse Effect;

                       (ii) such Pension Plan has not incurred any "accumulated
            funding deficiency" (as defined in Section 302 of ERISA) that could
            reasonably be expected to have a Material Adverse Effect;

                      (iii) no "reportable event" (as defined in Section 4043 of
            ERISA, but excluding such events as to which the PBGC has by
            regulation waived the requirement therein contained that it be
            notified within thirty days of the occurrence of such event) has
            occurred that could reasonably be expected to have a Material
            Adverse Effect; and

                       (iv) neither Borrower nor any of its Subsidiaries has
            engaged in any non-exempt "prohibited transaction" (as defined in
            Section 4975 of the Code) that could reasonably be expected to have
            a Material Adverse Effect.

                  (b) Neither Borrower nor any of its Subsidiaries has incurred
      or expects to incur any withdrawal liability to any Multiemployer Plan
      that could reasonably be expected to have a Material Adverse Effect.

            4.14 Regulation U; Investment Company Act. No part of the proceeds
of any Loan hereunder will be used to purchase or carry, or to extend credit to
others for the purpose of purchasing or carrying, any Margin Stock in violation

            4.15 Disclosure. No written statement made by a Senior Officer to
the Administrative Agent or any Lender in connection with this Agreement, or in
connection with any Loan, taken as a whole with other written statements
concurrently or theretofore made, as of the date thereof contained any untrue
statement of a material fact or omitted a material fact necessary to make the
statement made not misleading in light of all the circumstances existing at the
date the statement was made.

            4.16 Tax Liability. Borrower and its Subsidiaries have filed all tax
returns which are required to be filed, such returns are true, complete, correct
and in compliance with applicable Laws and Borrower and its Subsidiaries have
paid, or made provision for the payment of, all taxes shown to be due and
payable in said returns, or pursuant to any written assessment received by
Borrower or any of its Subsidiaries, except (a) such tax returns, taxes, fees or
other charges the amount or validity of which are being contested in good faith
by appropriate proceedings and as to which adequate reserves in respect to the
reasonably anticipated liability have been established and maintained and (b)
such returns or taxes which, if not filed or paid, would not constitute a
Material Adverse Effect.

            4.17 Projections. As of the Closing Date, to the best knowledge of
Borrower, the assumptions set forth in the Projections are reasonable and
consistent with each other and with all facts known to Borrower (including the
facts described in Schedule 4.17), and the Projections are reasonably based on

violation of any Hazardous Materials Law that would individually or in the

any Real Property except for such violations that would not individually or in
the aggregate constitute a Material Adverse Effect, (c) no Real Property or any
portion thereof is or has been utilized by Borrower or any of its Subsidiaries
or Predecessor as a site for the manufacture of any Hazardous Materials and (d)
to the extent that any Hazardous Materials are used, generated or stored by

                  (k) The occurrence of an Event of Default (as such term is or
      may hereafter be specifically defined in any other Loan Document in
      existence on the Closing Date) under any other Loan Document; or

                  (l) Any Pension Plan maintained by Borrower is finally
      determined by the PBGC to have a material "accumulated funding deficiency"

                  (a) Upon the occurrence, and during the continuance, of any
      Event of Default other than an Event of Default described in Section
      9.1(j):

                        (1) the Commitment to make Advances and all other
            obligations of the Administrative Agent or the Lenders and all
            rights of Borrower and any other Parties under the Loan Documents
            shall be suspended without notice to or demand upon Borrower, which
            are expressly waived by Borrower, except that all of the Lenders or
            the Requisite Lenders (as the case may be, in accordance with
            Section 11.2) may waive an Event of Default or, without waiving,
            determine, upon terms and conditions satisfactory to the Lenders or
            Requisite Lenders, as the case may be, to reinstate the Commitment
            and such other obligations and rights and make further Advances,
            which waiver or determination shall apply equally to, and shall be
            binding upon, all the Lenders;

                        (2)   [Intentionally Omitted]; and

                        (3) the Requisite Lenders may request the Administrative
            Agent to, and the Administrative Agent thereupon shall, terminate
            the Commitment and/or declare all or any part of the unpaid
            principal of all Notes, all interest accrued and unpaid thereon and
            all other amounts payable under the Loan Documents to be forthwith
            due and payable, whereupon the same shall become and be forthwith
            due and payable, without protest, presentment, notice of dishonor,

                        (2)   [Intentionally Omitted]; and

                        (3) the unpaid principal of all Notes, all interest
            accrued and unpaid thereon and all other amounts payable under the
            Loan Documents shall be forthwith due and payable, without protest,
            present ment, notice of dishonor, demand or further notice of any
            kind, all of which are expressly waived by Borrower.

                  (c) Upon the occurrence of any Event of Default, the Lenders
      and the Administrative Agent, or any of them, without notice to (except as
      expressly provided for in any Loan Document) or demand upon Borrower,
      which are expressly waived by Borrower (except as to notices expressly
      provided for in any Loan Document), may proceed (but only with the consent
      of the Requisite Lenders) to protect, exercise and enforce their rights
      and remedies under the Loan Documents against Borrower and any other Party
      and such other rights and remedies as are provided by Law or equity.

                  (d) The order and manner in which the Lenders' rights and
      remedies are to be exercised shall be determined by the Requisite Lenders
      in their sole discretion, and all payments received by the Administrative
      Agent and the Lenders, or any of them, shall be applied first to the costs
      and expenses (including reasonable attorneys' fees and disbursements and
      the reasonably allocated costs of attorneys employed by the Administrative
      Agent or by any Lender) of the Administrative Agent and of the Lenders,
      and thereafter paid pro rata to the Lenders in the same proportions that
      the aggregate Obligations owed to each Lender under the Loan Documents
      bear to the aggregate Obligations owed under the Loan Documents to all the
      Lenders, without priority or preference among the Lenders. Regardless of
      how each Lender may treat payments for the purpose of its own accounting,
      for the purpose of computing Borrower' Obligations hereunder and under the
      Notes, payments shall be applied first, to the costs and expenses of the
      Administrative Agent and the Lenders, as set forth above, second, to the
      payment of accrued and unpaid interest due under any Loan Documents to and
      including the date of such application (ratably, and without duplication,
      according to the accrued and unpaid interest due under each of the Loan
      Documents), and third, to the payment of all other amounts (including
      principal and fees) then owing to the Administrative Agent or the Lenders
      under the Loan Documents. No applica tion of payments will cure any Event
      of Default, or prevent acceleration, or continued acceleration, of amounts
      payable under the Loan Documents, or

                                   Article 10
                            THE ADMINISTRATIVE AGENT


            10.1 Appointment and Authorization. Subject to Section 10.8, each
Lender hereby irrevocably appoints and authorizes the Administrative Agent to
take such action as agent on its behalf and to exercise such powers under the
Loan Documents as are delegated to the Administrative Agent by the terms thereof
or are reasonably incidental, as determined by the Administrative Agent,
thereto. This appointment and authorization is intended solely for the purpose
of facilitating the servicing of the Loans and does not constitute appointment
of the Administrative Agent as trustee for any Lender or as representative of
any Lender for any other purpose and, except as specifically set forth in the
Loan Documents to the contrary, the Administrative Agent shall take such action
and exercise such powers only in an administrative and ministerial capacity.

            10.2 Administrative Agent and Affiliates. Bank of America National
Trust and Savings Association (and each successor Administrative Agent) has the
same rights and powers under the Loan Documents as any other Lender and may
exercise the same as though it were not the Administrative Agent, and the term
"Lender" or "Lenders" includes Bank of America, N.A. in its individual capacity.
Bank of America, N.A. (and each successor Administrative Agent) and its
Affiliates may accept deposits from, lend money to and generally engage in any
kind of banking, trust or other business with Borrower, any Subsidiary thereof,
or any Affiliate of Borrower or any Subsidiary thereof, as if it were not the
Administrative Agent and without any duty to account therefor to the Lenders.
Bank of America, N.A. (and each successor Administrative Agent) need not account
to any other Lender for any monies received by it for reimbursement of its costs
and expenses as Administrative Agent hereunder, or (subject to Section 11.10)
for any monies received by it in its capacity as a Lender hereunder. The
Administrative Agent shall not be deemed to hold a fiduciary relationship with
any Lender and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into this Agreement or otherwise exist
against the Administrative Agent.

            10.3 Proportionate Interest in any Collateral. The Administrative
Agent, on behalf of all the Lenders, shall hold in accordance with the Loan
Documents all items of any collateral or interests therein received or held by
the Administrative Agent. Subject to the Administrative Agent's and the Lenders'
rights to reimbursement for their costs and expenses hereunder (including
reasonable attorneys' fees and disbursements and other professional services and
the reasonably allocated costs of









                                      -71-

<PAGE>   79



attorneys employed by the Administrative Agent or a Lender) and subject to the
application of payments in accordance with Section 9.2(d), each Lender shall
have an interest in the Lenders' interest in such collateral or interests
therein in the same proportions that the aggregate Obligations owed such Lender
under the Loan Documents bear to the aggregate Obligations owed under the Loan
Documents to all the Lenders, without priority or preference among the Lenders.

            10.4 Lenders' Credit Decisions. Each Lender agrees that it has,
independently and without reliance upon the Administrative Agent, any other
Lender or the directors, officers, agents, employees or attorneys of the
Administrative Agent or of any other Lender, and instead in reliance upon
information supplied to it by or on behalf of Borrower and upon such other
information as it has deemed appropriate, made its own independent credit
analysis and decision to enter into this Agreement. Each Lender also agrees that
it shall, independently and without reliance upon the Administrative Agent, any
other Lender or the directors, officers, agents, employees or attorneys of the
Administrative Agent or of any other Lender, continue to make its own
independent credit analyses and decisions in acting or not acting under the Loan
Documents.

            10.5  Action by Administrative Agent.

                  (a) Absent actual knowledge of the Administrative Agent of the
      existence of a Default, the Administrative Agent may assume that no
      Default has occurred and is continuing, unless the Administrative Agent
      (or the Lender that is then the Administrative Agent) has received notice
      from Borrower stating the nature of the Default or has received notice
      from a Lender stating the nature of the Default and that such Lender
      considers the Default to have occurred and to be continuing.

                  (b) The Administrative Agent has only those obligations under
      the Loan Documents as are expressly set forth therein.

                  (c) Except for any obligation expressly set forth in the Loan
      Documents and as long as the Administrative Agent may assume that no Event
      of Default has occurred and is continuing, the Administrative Agent may,
      but shall not be required to, exercise its discretion to act or not act,
      except that the Administrative Agent shall be required to act or not act
      upon the instructions of the Requisite Lenders (or of all the Lenders, to
      the extent required by Section 11.2) and those instructions shall be
      binding upon the Administrative Agent and all the Lenders, provided that
      the Administrative Agent shall not be









                                      -72-

<PAGE>   80



      required to act or not act if to do so would be contrary to any Loan
      Document or to applicable Law or would result, in the reasonable judgment
      of the Administrative Agent, in substantial risk of liability to the
      Administrative Agent.

                  (d) If the Administrative Agent has received a notice
      specified in clause (a), the Administrative Agent shall immediately give
      notice thereof to the Lenders and shall act or not act upon the
      instructions of the Requisite Lenders (or of all the Lenders, to the
      extent required by Section 11.2), provided that the Administrative Agent
      shall not be required to act or not act if to do so would be contrary to
      any Loan Document or to applicable Law or would result, in the reasonable
      judgment of the Administrative Agent, in substantial risk of liability to
      the Administrative Agent, and except that if the Requisite Lenders (or all
      the Lenders, if required under Section 11.2) fail, for five (5) Banking
      Days after the receipt of notice from the Administrative Agent, to
      instruct the Administrative Agent, then the Administrative Agent, in its
      sole discretion, may act or not act as it deems advisable for the
      protection of the interests of the Lenders.

                  (e) The Administrative Agent shall have no liability to any
      Lender for acting, or not acting, as instructed by the Requisite Lenders
      (or all the Lenders, if required under Section 11.2), notwithstanding any
      other provision hereof.

            10.6 Liability of Administrative Agent. Neither the Administrative
Agent nor any of its directors, officers, agents, employees or attorneys shall
be liable for any action taken or not taken by them under or in connection with
the Loan Documents, except for their own gross negligence or willful misconduct.
Without limitation on the foregoing, the Administrative Agent and its directors,
officers, agents, employees and attorneys:

                  (a) May treat the payee of any Note as the holder thereof
      until the Administrative Agent receives notice of the assignment or
      transfer thereof, in form satisfactory to the Administrative Agent, signed
      by the payee, and may treat each Lender as the owner of that Lender's
      interest in the Obligations for all purposes of this Agreement until the
      Administrative Agent receives notice of the assignment or transfer
      thereof, in form satisfactory to the Administrative Agent, signed by that
      Lender;










                                      -73-

<PAGE>   81



                  (b) May consult with legal counsel (including in-house legal
      counsel), accountants (including in-house accountants) and other
      professionals or experts selected by it, or with legal counsel,
      accountants or other profes sionals or experts for Borrower and/or their
      Subsidiaries or the Lenders, and shall not be liable for any action taken
      or not taken by it in good faith in accordance with any advice of such
      legal counsel, accountants or other professionals or experts;

                  (c) Shall not be responsible to any Lender for any statement,
      warranty or representation made in any of the Loan Documents or in any
      notice, certificate, report, request or other statement (written or oral)
      given or made in connection with any of the Loan Documents;

                  (d) Except to the extent expressly set forth in the Loan
      Documents, shall have no duty to ask or inquire as to the performance or
      observance by Borrower or its Subsidiaries of any of the terms, conditions
      or covenants of any of the Loan Documents or to inspect any collateral or
      any Property, books or records of Borrower or their Subsidiaries;

                  (e) Will not be responsible to any Lender for the due
      execution, legality, validity, enforceability, genuineness, effectiveness,
      sufficiency or value of any Loan Document, any other instrument or writing
      furnished pursuant thereto or in connection therewith, or any collateral;

                  (f) Will not incur any liability by acting or not acting in
      reliance upon any Loan Document, notice, consent, certificate, statement,
      request or other instrument or writing believed in good faith by it to be
      genuine and signed or sent by the proper party or parties; and

                  (g) Will not incur any liability for any arithmetical error in
      computing any amount paid or payable by Borrower or any Subsidiary or
      Affiliate thereof or paid or payable to or received or receivable from any
      Lender under any Loan Document, including, without limitation, principal,
      interest, commitment fees, Advances and other amounts; provided that,
      promptly upon discovery of such an error in computation, the
      Administrative Agent, the Lenders and (to the extent applicable) Borrower
      and/or its Subsidiaries or Affiliates shall make such adjustments as are
      necessary to correct such error and to restore the parties to the position
      that they would have occupied had the error not occurred.










                                      -74-

<PAGE>   82



            10.7 Indemnification. Each Lender shall, ratably in accordance with
its Pro Rata Share of the Commitment (if the Commitment is then in effect) or in
accordance with its proportion of the aggregate Indebtedness then evidenced by
the Notes (if the Commitment has then been terminated), indemnify and hold the
Administrative Agent and its directors, officers, agents, employees and
attorneys harmless against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind or nature whatsoever (including reasonable attorneys' fees and
disbursements and allocated costs of attorneys employed by the Administrative
Agent) that may be imposed on, incurred by or asserted against it or them in any
way relating to or arising out of the Loan Documents (other than losses incurred
by reason of the failure of Borrower to pay the Indebtedness represented by the
Notes) or any action taken or not taken by it as Administrative Agent
thereunder, except such as result from its own gross negligence or willful
misconduct. Without limitation on the foregoing, each Lender shall reimburse the
Administrative Agent upon demand for that Lender's Pro Rata Share of any
out-of-pocket cost or expense incurred by the Administrative Agent in connection
with the negotiation, preparation, execution, delivery, amendment, waiver,
restruc turing, reorganization (including a bankruptcy reorganization),
enforcement or attempted enforcement of the Loan Documents, to the extent that
Borrower or any other Party is required by Section 11.3 to pay that cost or
expense but fails to do so upon demand. Nothing in this Section 10.7 shall
entitle the Administrative Agent or any indemnitee referred to above to recover
any amount from the Lenders if and to the extent that such amount has
theretofore been recovered from Borrower or any of its Subsidiaries. To the
extent that the Administrative Agent or any indemnitee referred to above is
later reimbursed such amount by Borrower or any of its Subsidiaries, it shall
return the amounts paid to it by the Lenders in respect of such amount.

            10.8 Successor Administrative Agent. The Administrative Agent may,
and at the request of the Requisite Lenders shall, resign as Administrative
Agent upon reasonable notice to the Lenders and Borrower effective upon
acceptance of appointment by a successor Administrative Agent. If the
Administrative Agent shall resign as Administrative Agent under this Agreement,
the Requisite Lenders shall appoint from among the Lenders a successor
Administrative Agent for the Lenders, which successor Administrative Agent shall
be approved by Borrower (and such approval shall not be unreasonably withheld or
delayed). If no successor Administrative Agent is appointed prior to the
effective date of the resignation of the Administrative Agent, the
Administrative Agent may appoint, after consulting with the Lenders and
Borrower, a successor Administrative Agent from among the Lenders. Upon the
acceptance of its appointment as successor Administrative Agent hereunder, such
successor Administrative Agent shall succeed to all the rights, powers and
duties









                                      -75-

<PAGE>   83



of the retiring Administrative Agent and the term "Administrative Agent" shall
mean such successor Administrative Agent and the retiring Administrative Agent's
appointment, powers and duties as Administrative Agent shall be terminated.
After any retiring Administrative Agent's resignation hereunder as
Administrative Agent, the provisions of this Article 10, and Sections 11.3,
11.11 and 11.22, shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was Administrative Agent under this Agreement.
Notwithstanding the foregoing, if (a) the Administrative Agent has not been paid
its agency fees under Section 3.2 or has not been reimbursed for any expense
reimbursable to it under Section 11.3, in either case for a period of at least
one (1) year and (b) no successor Administrative Agent has accepted appointment
as Administrative Agent by the date which is thirty (30) days following a
retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall perform all of the duties of the Administrative Agent
hereunder until such time, if any, as the Requisite Lenders appoint a successor
Administrative Agent as provided for above.

            10.9 No Obligations of Borrower. Nothing contained in this Article
10 shall be deemed to impose upon Borrower any obligation in respect of the due
and punctual performance by the Administrative Agent of its obligations to the
Lenders under any provision of this Agreement, and Borrower shall have no
liability to the Administrative Agent or any of the Lenders in respect of any
failure by the Administrative Agent or any Lender to perform any of its
obligations to the Administrative Agent or the Lenders under this Agreement.
Without limiting the generality of the foregoing, where any provision of this
Agreement relating to the payment of any amounts due and owing under the Loan
Documents provides that such payments shall be made by Borrower to the
Administrative Agent for the account of the Lenders, Borrower's obligations to
the Lenders in respect of such payments shall be deemed to be satisfied upon the
making of such payments to the Administrative Agent in the manner provided by
this Agreement. In addition, Borrower may rely on a written statement by the
Administrative Agent to the effect that it has obtained the written consent of
the Requisite Lenders or all of the Lenders, as applicable under Section 11.2,
in connection with a waiver, amendment, consent, approval or other action by the
Lenders hereunder, and shall have no obligation to verify or confirm the same.

                                  MISCELLANEOUS


            11.1 Cumulative Remedies; No Waiver. The rights, powers, privileges
and remedies of the Administrative Agent and the Lenders provided herein or in
any Note or other Loan Document are cumulative and not exclusive of any right,
power, privilege or remedy provided by Law or equity. No failure or delay on the
part of the Administrative Agent or any Lender in exercising any right, power,
privilege or remedy may be, or may be deemed to be, a waiver thereof; nor may
any single or partial exercise of any right, power, privilege or remedy preclude
any other or further exercise of the same or any other right, power, privilege
or remedy. The terms and conditions of Article 8 hereof are inserted for the
sole benefit of the Administrative Agent and the Lenders; the same may be waived
in whole or in part, with or without terms or conditions, in respect of any Loan
without prejudicing the Administrative Agent's or the Lenders' rights to assert
them in whole or in part in respect of any other Loan.

            11.2 Amendments; Consents. No amendment, modification, supplement,
extension, termination or waiver of any provision of this Agreement or any other
Loan Document, no approval or consent thereunder, and no consent to any
departure by Borrower or any other Party therefrom, may in any event be
effective unless in writing signed by the Administrative Agent with the written
approval of the Requisite Lenders (and, in the case of any amendment,
modification or supplement of or to any Loan Document to which Borrower is a
Party, signed by Borrower, and, in the case of any amendment, modification or
supplement to Article 10, signed by the Administrative Agent), and then only in
the specific instance and for the specific purpose given; and, without the
approval in writing of all the Lenders, no amendment, modification, supplement,
termination, waiver or consent may be effective:

                  (a) To amend or modify the principal of, or the amount of
      principal, principal prepayments or the rate of interest payable on, any
      Note, or the amount of the Commitment or the Pro Rata Share of any Lender
      or the amount of any commitment fee payable to any Lender, or any other
      fee or amount payable to any Lender under the Loan Documents or to waive
      an Event of Default consisting of the failure of Borrower to pay when due
      principal, interest or any fee;










                                      -77-

<PAGE>   85



                  (b) To postpone any date fixed for any payment of principal
      of, prepayment of principal of or any installment of interest on, any Note
      or any installment of any fee, or to extend the term of the Commitment;
                  (c) To amend the provisions of the definition of "Requisite
      Lenders", "Conversion Date", "Maturity Date"; or

                  (d) To release any material Subsidiary Guarantor from the
      Subsidiary Guaranty; or

                  (e) To amend or waive Article 8 or this Section 11.2; or

                  (f) To amend any provision of this Agreement that expressly
      requires the consent or approval of all the Lenders.

Any amendment, modification, supplement, termination, waiver or consent pursuant
to this Section 11.2 shall apply equally to, and shall be binding upon, all the
Lenders and the Administrative Agent.

            11.3 Costs, Expenses and Taxes. Borrower shall pay within twenty
(20) Banking Days after demand, accompanied by an invoice therefor, the
reasonable costs and expenses of the Administrative Agent in connection with the
negotiation, preparation, syndication, execution and delivery of the Loan
Documents and any amendment thereto or waiver thereof. Borrower shall also pay
on demand, accompanied by an invoice therefor, the reasonable costs and expenses
of the Administrative Agent and the Lenders in connection with the refinancing,
restructur ing, reorganization (including a bankruptcy reorganization) and
enforcement or attempted enforcement of the Loan Documents, and any matter
related thereto. The foregoing costs and expenses shall include filing fees,
recording fees, title insurance fees, appraisal fees, search fees, and other
out-of-pocket expenses and the reasonable fees and out-of-pocket expenses of any
legal counsel (including reasonably allocated costs of legal counsel employed by
the Administrative Agent or any Lender), independent public accountants and
other outside experts retained by the Administrative Agent or any Lender,
whether or not such costs and expenses are incurred or suffered by the
Administrative Agent or any Lender in connection with or during the course of
any bankruptcy or insolvency proceedings of any of Borrower or any Subsidiary
thereof. Borrower shall pay any and all documentary and other taxes that may be
payable in connection with the execution and delivery of the Loan Documents and
agrees to hold harmless and indemnify on the terms set forth in 11.11 the
Administrative Agent and the Lenders from and against any and all loss,
liability or legal or other expense with respect to or resulting from any delay
in paying or failure to









                                      -78-

<PAGE>   86



pay any such tax, cost, expense, fee or charge or that any of them may suffer or
incur by reason of the failure of any Party to perform any of its Obligations.

            11.4 Nature of Lenders' Obligations. The obligations of the Lenders
hereunder are several and not joint or joint and several. Nothing contained in
this Agreement or any other Loan Document and no action taken by the
Administrative Agent or the Lenders or any of them pursuant hereto or thereto
may, or may be deemed to, make the Lenders a partnership, an association, a
joint venture or other entity, either among themselves or with the Borrower or
any Affiliate of any of Borrower. A default by any Lender will not increase the
Pro Rata Share of the Commitments attributable to any other Lender. Any Lender
not in default may, if it desires, assume in such proportion as the
nondefaulting Lenders agree the obligations of any Lender in default, but is not
obligated to do so. The Administrative Agent agrees that it will use its best
efforts either to induce promptly the other Lenders to assume the obligations of
a Lender in default or to obtain promptly another Lender, reasonably
satisfactory to Borrower, to replace such a Lender in default.

            11.5 Survival of Representations and Warranties. All representations
and warranties contained herein or in any other Loan Document, or in any
certificate or other writing delivered by or on behalf of any one or more of the
Parties to any Loan Document, will survive the making of the Loans hereunder and
the execution and delivery of the Notes, and have been or will be relied upon by
the Administrative Agent and each Lender, notwithstanding any investigation made
by the Administrative Agent or any Lender or on their behalf.

            11.6 Notices. Except as otherwise expressly provided in the Loan
Documents, all notices, requests, demands, directions and other communications
provided for hereunder or under any other Loan Document must be in writing and
must be mailed, telegraphed, telecopied, dispatched by commercial courier or
delivered to the appropriate party at the address set forth on the signature
pages of this Agreement or other applicable Loan Document or, as to any party to
any Loan Document, at any other address as may be designated by it in a written
notice sent to all other parties to such Loan Document in accordance with this
Section. Except as otherwise expressly provided in any Loan Document, if any
notice, request, demand, direction or other communication required or permitted
by any Loan Document is given by mail it will be effective on the earlier of
receipt or the fourth Banking Day after deposit in the United States mail with
first class or airmail postage prepaid; if given by telegraph or cable, when
delivered to the telegraph company with charges prepaid; if given by telecopier,
when sent; if dispatched by commercial courier, on the scheduled delivery date;
or if given by personal delivery, when delivered.

            11.7 Execution of Loan Documents. Unless the Administrative Agent
otherwise specifies with respect to any Loan Document, (a) this Agreement and
any other Loan Document may be executed in any number of counterparts and any
party hereto or thereto may execute any counterpart, each of which when executed
and delivered will be deemed to be an original and all of which counterparts of
this Agreement or any other Loan Document, as the case may be, when taken
together will be deemed to be but one and the same instrument and (b) execution
of any such counterpart may be evidenced by a telecopier transmission of the
signature of such party. The execution of this Agreement or any other Loan
Document by any party hereto or thereto will not become effective until
counterparts hereof or thereof, as the case may be, have been executed by all
the parties hereto or thereto.

            11.8  Binding Effect; Assignment.

                  (a) This Agreement and the other Loan Documents to which
      Borrower is a Party will be binding upon and inure to the benefit of
      Borrower, the Administrative Agent, each of the Lenders, and their
      respective successors and assigns, except that Borrower may not assign its
      rights hereunder or thereunder or any interest herein or therein without
      the prior written consent of all the Lenders. Each Lender represents that
      it is not acquiring its Note with a view to the distribution thereof
      within the meaning of the Securities Act of 1933, as amended (subject to
      any requirement that disposition of such Note must be within the control
      of such Lender). Any Lender may at any time pledge its Note or any other
      instrument evidencing its rights as a Lender under this Agreement to a
      Federal Reserve Bank, but no such pledge shall release that Lender from
      its obligations hereunder or grant to such Federal Reserve Bank the rights
      of a Lender hereunder absent foreclosure of such pledge.

                  (b) From time to time following the Closing Date, each Lender
      may assign to one or more Eligible Assignees all or any portion of its Pro
      Rata Share of the Commitment; provided that (i) such Eligible Assignee, if
      not then a Lender or an Affiliate of the assigning Lender, shall be
      approved by the Administrative Agent and (if no Event of Default then
      exists) Borrower (neither of which approvals shall be unreasonably
      withheld or delayed), (ii) such assign ment shall be evidenced by a
      Commitment Assignment and Acceptance, a copy of which shall be furnished
      to the Administrative Agent as hereinbelow provided, (iii) except in the
      case of an assignment to an Affiliate of the assigning Lender, to another
      Lender or of the entire remaining Commitment of the assigning Lender, the
      assignment shall not assign a Pro Rata Share of the









                                      -80-

<PAGE>   88



      Commitment that is equivalent to less than $5,000,000, (iv) [Intentionally
      Omitted]; (v) [Intentionally Omitted], and (vi) the effective date of any
      such assignment shall be as specified in the Commitment Assignment and
      Acceptance, but not earlier than the date which is five (5) Banking Days
      after the date the Administrative Agent has received the Commitment
      Assignment and Acceptance, unless otherwise consented to by the
      Administrative Agent. Upon the effective date of such Commitment
      Assignment and Acceptance, the Eligible Assignee named therein shall be a
      Lender for all purposes of this Agreement, with the Pro Rata Share of the
      Commitment therein set forth and, to the extent of such Pro Rata Share,
      the assigning Lender shall be released from its further obligations under
      this Agreement. Borrower agrees that it shall execute and deliver (against
      delivery by the assigning Lender to Borrower of its Note) to such assignee
      Lender, a Note evidencing that assignee Lender's Pro Rata Share of the
      Commitment, and to the assigning Lender, a Note evidencing the remaining
      balance Pro Rata Share retained by the assigning Lender.

                  (c) By executing and delivering a Commitment Assignment and
      Acceptance, the Eligible Assignee thereunder acknowledges and agrees that:
      (i) other than the representation and warranty that it is the legal and
      beneficial owner of the Pro Rata Share of the Commitment being assigned
      thereby free and clear of any adverse claim, the assigning Lender has made
      no representation or warranty and assumes no responsibility with respect
      to any statements, warranties or representations made in or in connection
      with this Agreement or the execution, legality, validity, enforceability,
      genuineness or sufficiency of this Agreement or any other Loan Document;
      (ii) the assigning Lender has made no representation or warranty and
      assumes no responsibility with respect to the financial condition of
      Borrower or the performance by Borrower of the Obligations; (iii) it has
      received a copy of this Agreement, together with copies of the most recent
      financial statements delivered pursuant to Section 7.1 and such other
      documents and information as it has deemed appropriate to make its own
      credit analysis and decision to enter into such Commitment Assignment and
      Acceptance; (iv) it will, independently and without reliance upon the
      Administrative Agent or any Lender and based on such documents and
      information as it shall deem appropriate at the time, conti nue to make
      its own credit decisions in taking or not taking action under this
      Agreement; (v) it appoints and authorizes the Administrative Agent to take
      such action and to exercise such powers under this Agreement as are
      delegated to the Administrative Agent by this Agreement; and (vi) it will
      perform in accordance with their terms all of the obligations which by the
      terms of this Agreement are required to be performed by it as a Lender.

<PAGE>   89




                  (d) The Administrative Agent shall maintain at the
      Administrative Agent's Office a copy of each Commitment Assignment and
      Acceptance delivered to it and a register (the "Register") of the names
      and address of each of the Lenders and the Pro Rata Share of the
      Commitment held by each Lender, giving effect to each Commitment
      Assignment and Acceptance. The Register shall be available during normal
      business hours for inspection by Borrower or any Lender upon reasonable
      prior notice to the Administrative Agent. After receipt of a completed
      Commitment Assignment and Acceptance executed by any Lender and an
      Eligible Assignee, and receipt of an assignment fee of $3,000 from such
      Lender or Eligible Assignee, the Administrative Agent shall, promptly
      following the effective date thereof, provide to Borrower and the Lenders
      a revised Schedule 1.1 giving effect there to. Borrower, the
      Administrative Agent and the Lenders shall deem and treat the Persons
      listed as Lenders in the Register as the holders and owners of the Pro
      Rata Share of the Commitment listed therein for all purposes hereof, and
      no assignment or transfer of any such Pro Rata Share of the Commitment
      shall be effective, in each case unless and until a Commitment Assignment
      and Acceptance effecting the assignment or transfer thereof shall have
      been accepted by the Administrative Agent and recorded in the Register as
      provided above. Prior to such recordation, all amounts owed with respect
      to the applicable Pro Rata Share of the Commitment shall be owed to the
      Lender listed in the Register as the owner thereof, and any request,
      authority or consent of any Person who, at the time of making such request
      or giving such authority or consent, is listed in the Register as a Lender
      shall be conclusive and binding on any subsequent holder, assignee or
      transferee of the corresponding Pro Rata Share of the Commitment.

                  (e) Each Lender may from time to time grant participations to
      one or more banks or other financial institutions in a portion of its Pro
      Rata Share of the Commitment; provided, however, that (i) such Lender's
      obligations under this Agreement shall remain unchanged, (ii) such Lender
      shall remain solely responsible to the other parties hereto for the
      performance of such obligations, (iii) the participating banks or other
      financial institutions shall not be a Lender hereunder for any purpose
      except, if the participation agreement so provides, for the purposes of
      Sections 3.7, 3.8, 11.11 and 11.22 but only to the extent that the cost of
      such benefits to Borrower does not exceed the cost which Borrower would
      have incurred in respect of such Lender absent the participa tion, (iv)
      Borrower, the Administrative Agent and the other Lenders shall continue to
      deal solely and directly with such Lender in connection with such









                                      -82-

<PAGE>   90



      Lender's rights and obligations under this Agreement, (v) the
      participation interest shall be expressed as a percentage of the granting
      Lender's Pro Rata Share of the Commitment as it then exists and shall not
      restrict an increase in the Commitment, or in the granting Lender's Pro
      Rata Share of the Commitment, so long as the amount of the participation
      interest is not affected thereby and (vi) the consent of the holder of
      such participation interest shall not be required for amendments or
      waivers of provisions of the Loan Documents other than those which (A)
      extend the Maturity Date or any other date upon which any payment of money
      is due to the Lenders, (B) reduce the rate of interest on the Notes, any
      fee or any other monetary amount payable to the Lenders, (C) reduce the
      amount of any installment of principal due under the Notes or (D) release
      any material Subsidiary Guarantor from the Subsidiary Guaranty.

                  (f) Notwithstanding anything to the contrary contained herein,
      any Lender (a "Granting Lender") may grant to a special purpose conduit
      funding vehicle (an "SPC") identified as such in a writing delivered from
      time to time by the Granting Lender to the Administrative Agent and
      Borrower, the option to fund all or any part of any Loan that such
      Granting Lender would otherwise be obligated to fund pursuant to this
      Agreement; provided that (i) nothing herein shall constitute a commitment
      by an SPC to fund any Loan, (ii) the Granting Lender shall remain
      obligated to fund such Loan pursuant to the terms hereof unless and until
      the SPC actually funds such Loan in full, (iii) the SPC shall be subject
      to all of the restrictions hereunder applicable to its Granting Lender and
      shall have no rights hereunder beyond any derived from its Granting
      Lender, (iv) the Administrative Agent, Borrower and the other Lenders
      shall continue to deal only with the Granting Lender respecting this
      Agreement and no such option shall, and no such funding shall (except as
      to the funding of that Loan), release the Granting Lender of any
      obligation hereunder, and (v) such SPC must be a party to an agreement
      with the Granting Lender containing provisions substantially similar to
      Section 11.14 (provided, however, that such agreement may permit such SPC
      to disclose on a confidential basis on terms substantially similar to
      Section 11.14 any non-public information relating to its funding of Loans
      to any rating agency, commercial paper dealer or provider of any surety or
      guarantee to such SPC) and provide a copy thereof to the Administrative
      Agent and Borrower. The Loans made by an SPC shall be evidenced by the
      Note of its Granting Lender. Payments made by Borrower to a Granting
      Lender in respect of a Loan made by its SPC shall be deemed payments made
      to such SPC and neither the Administrative Agent nor Borrower shall have
      any responsibility to an SPC as to any payments made to its Granting









                                      -83-

<PAGE>   91



      Lender. Any consent or approval given by a Granting Lender pursuant to
      Section 11.2 shall be conclusive as against any SPC of that Granting
      Lender, notwithstanding the failure of the SPC to approve such consent or
      approval. The funding of a Loan by an SPC hereunder shall utilize the Pro
      Rata Share of the Commitment of the Granting Lender to the same extent as
      if such Loan were funded by such Granting Lender. No SPC shall be liable
      for any indemnity or payment under this Agreement (all liability for which
      shall remain with the Granting Lender). This Section 11.8(f) may not be
      amended without the written consent of each Granting Lender, all or any
      part of whose Loan is being funded by an SPC designated to the
      Administrative Agent and Borrower as provided above as of the time of such
      amendment.

            11.9 Right of Setoff. If an Event of Default has occurred and is
continuing, the Administrative Agent or any Lender may exercise its rights under
applicable Laws and, to the extent permitted by applicable Laws, apply any funds
in any deposit account maintained with it by Borrower and/or any Property of
Borrower in its possession against the Obligations.

            11.10 Sharing of Setoffs. Each Lender severally agrees that if it,
through the exercise of any right of setoff, banker's lien or counterclaim
against Borrower, or otherwise, receives payment of the Obligations held by it
that is ratably more than any other Lender, through any means, receives in
payment of the Obligations held by that Lender, then, subject to applicable
Laws: (a) the Lender exercising the right of setoff, banker's lien or
counterclaim or otherwise receiving such payment shall purchase, and shall be
deemed to have simultaneously purchased, from each of the other Lenders a
participation in the Obligations held by the other Lenders and shall pay to the
other Lenders a purchase price in an amount so that the share of the Obligations
held by each Lender after the exercise of the right of setoff, banker's lien or
counterclaim or receipt of payment shall be in the same proportion that existed
prior to the exercise of the right of setoff, banker's lien or counterclaim or
receipt of payment; and (b) such other adjustments and purchases of
participations shall be made from time to time as shall be equitable to ensure
that all of the Lenders share any payment obtained in respect of the Obligations
ratably in accordance with each Lender's share of the Obligations immediately
prior to, and without taking into account, the payment; provided that, if all or
any portion of a disproportionate payment obtained as a result of the exercise
of the right of setoff, banker's lien, counterclaim or otherwise is thereafter
recovered from the purchasing Lender by Borrower or any Person claiming through
or succeeding to the rights of Borrower, the purchase of a participation shall
be rescinded and the purchase price thereof shall be restored to the extent of
the recovery, but without interest. Each Lender that purchases a participation









                                      -84-

<PAGE>   92



in the Obligations pursuant to this Section 11.10 shall from and after the
purchase have the right to give all notices, requests, demands, directions and
other communications under this Agreement with respect to the portion of the
Obligations purchased to the same extent as though the purchasing Lender were
the original owner of the Obligations purchased. Borrower expressly consents to
the foregoing arrangements and agrees that any Lender holding a participation in
an Obligation so purchased pursuant to this Section 11.10 may exercise any and
all rights of setoff, banker's lien or counterclaim with respect to the
participation as fully as if the Lender were the original owner of the
Obligation purchased.

            11.11 Indemnity by Borrower. Borrower agrees to indemnify, save and
hold harmless the Administrative Agent and each Lender and their respective
Affiliates, directors, officers, agents, attorneys and employees (collectively
the "Indemnitees") from and against: (a) any and all claims, demands, actions or
causes of action (except a claim, demand, action, or cause of action for any
amount excluded from the definition of "Taxes" in Section 3.12(d)) if the claim,
demand, action or cause of action arises out of or relates to any act or
omission (or alleged act or omission) of Borrower, its Affiliates or any of its
officers, directors or stockholders relating to the Commitment, the use or
contemplated use of proceeds of any Loan, or the relationship of Borrower and
the Lenders under this Agreement; (b) any administrative or investigative
proceeding by any Governmental Agency arising out of or related to a claim,
demand, action or cause of action described in clause (a) above; and (c) any and
all liabilities, losses, costs or expenses (including reasonable attorneys' fees
and the reasonably allocated costs of attorneys employed by any Indemnitee and
disbursements of such attorneys and other professional services) that any
Indemnitee suffers or incurs as a result of the assertion of any foregoing
claim, demand, action or cause of action; provided that no Indemnitee shall be
entitled to indemnification for any loss caused by its own gross negligence or
willful misconduct or for any loss asserted against it by another Indemnitee. If
any claim, demand, action or cause of action is asserted against any Indemnitee,
such Indemnitee shall promptly notify Borrower, but the failure to so promptly
notify Borrower shall not affect Borrower's obligations under this Section
unless such failure materially prejudices Borrower's right to participate in the
contest of such claim, demand, action or cause of action, as hereinafter
provided. Such Indemnitee may (and shall, if requested by Borrower in writing)
contest the validity, applicability and amount of such claim, demand, action or
cause of action and shall permit Borrower to participate in such contest. Any
Indemnitee that proposes to settle or compromise any claim or proceeding for
which Borrower may be liable for payment of indemnity hereunder shall give
Borrower written notice of the terms of such proposed settlement or compromise
reasonably in advance of settling or compromising such claim or proceeding and
shall obtain Borrower's prior consent (which shall not be









                                      -85-

<PAGE>   93



unreasonably withheld or delayed). In connection with any claim, demand, action
or cause of action covered by this Section 11.11 against more than one
Indemnitee, all such Indemnitees shall be represented by the same legal counsel
(which may be a law firm engaged by the Indemnitees or attorneys employed by an
Indemnitee or a combination of the foregoing) selected by the Indemnitees and
reasonably acceptable to Borrower; provided, that if such legal counsel
determines in good faith that representing all such Indemnitees would or could
result in a conflict of interest under Laws or ethical principles applicable to
such legal counsel or that a defense or counter claim is available to an
Indemnitee that is not available to all such Indemnitees, then to the extent
reasonably necessary to avoid such a conflict of interest or to permit
unqualified assertion of such a defense or counterclaim, each affected
Indemnitee shall be entitled to separate representation by legal counsel
selected by that Indemnitee and reasonably acceptable to Borrower, with all such
legal counsel using reasonable efforts to avoid unnecessary duplication of
effort by counsel for all Indemnitees; and further provided that the
Administrative Agent (as an Indemnitee) shall at all times be entitled to
representation by separate legal counsel (which may be a law firm or attorneys
employed by the Administrative Agent or a combination of the foregoing). Any
obligation or liability of Borrower to any Indemnitee under this Section 11.11
shall survive the expiration or termination of this Agreement and the repayment
of all Loans and the payment and performance of all other Obligations owed to
the Lenders.

            11.12 Nonliability of the Lenders. Borrower acknowledges and agrees
that:

                  (a) Any inspections of any Property of Borrower made by or
      through the Administrative Agent or the Lenders are for purposes of
      administration of the Loan only and Borrower is not entitled to rely upon
      the same (whether or not such inspections are at the expense of Borrower);

                  (b) By accepting or approving anything required to be
      observed, performed, fulfilled or given to the Administrative Agent or the
      Lenders pursuant to the Loan Documents, neither the Administrative Agent
      nor the Lenders shall be deemed to have warranted or represented the
      sufficiency, legality, effectiveness or legal effect of the same, or of
      any term, provision or condition thereof, and such acceptance or approval
      thereof shall not constitute a warranty or representation to anyone with
      respect thereto by the Administrative Agent or the Lenders;

                  (c) The relationship between Borrower and the Administrative
      Agent and the Lenders is, and shall at all times remain, solely that of
      borrowers









                                      -86-

<PAGE>   94



      and lenders; neither the Administrative Agent nor the Lenders shall under
      any circumstance be construed to be partners or joint venturers of
      Borrower or its Affiliates; neither the Administrative Agent nor the
      Lenders shall under any circumstance be deemed to be in a relationship of
      confidence or trust or a fiduciary relationship with Borrower or its
      Affiliates, or to owe any fiduciary duty to Borrower or its Affiliates;
      neither the Administrative Agent nor the Lenders undertake or assume any
      responsibility or duty to Borrower or its Affiliates to select, review,
      inspect, supervise, pass judgment upon or inform Borrower or its
      Affiliates of any matter in connection with their Property or the
      operations of Borrower or its Affiliates; Borrower and its Affiliates
      shall rely entirely upon their own judgment with respect to such matters;
      and any review, inspection, supervision, exercise of judgment or supply of
      information undertaken or assumed by the Administrative Agent or the
      Lenders in connection with such matters is solely for the protection of
      the Administrative Agent and the Lenders and neither Borrower nor any
      other Person is entitled to rely thereon; and

                  (d) The Administrative Agent and the Lenders shall not be
      responsible or liable to any Person for any loss, damage, liability or
      claim of any kind relating to injury or death to Persons or damage to
      Property caused by the actions, inaction or negligence of Borrower and/or
      its Affiliates and Borrower hereby indemnify and hold the Administrative
      Agent and the Lenders harmless on the terms set forth in Section 11.11
      from any such loss, damage, liability or claim.

            11.13 No Third Parties Benefitted. This Agreement is made for the
purpose of defining and setting forth certain obligations, rights and duties of
Borrower, the Administrative Agent and the Lenders in connection with the Loans,
and is made for the sole benefit of Borrower and its Subsidiaries, the
Administrative Agent and the Lenders, and the Administrative Agent's and the
Lenders' successors and assigns. Except as provided in Sections 11.8 and 11.11,
no other Person shall have any rights of any nature hereunder or by reason
hereof.

            11.14 Confidentiality. Each Lender agrees to hold any confidential
information that it may receive from Borrower pursuant to this Agreement in
confidence, except for disclosure: (a) to other Lenders or Affiliates of a
Lender; (b) to legal counsel and accountants for Borrower or any Lender; (c) to
other professional advisors to Borrower or any Lender, provided that the
recipient has accepted such information subject to a confidentiality agreement
substantially similar to this Section 11.14; (d) to regulatory officials having
jurisdiction over that Lender; (e) as









                                      -87-

<PAGE>   95



required by Law or legal process, provided that each Lender agrees to notify
Borrower of any such disclosures unless prohibited by applicable Laws, or in
connection with any legal proceeding to which that Lender and Borrower are
adverse parties; and (f) to another financial institution in connection with a
disposition or proposed disposition to that financial institution of all or part
of that Lender's interests hereunder or a parti cipation interest in its Notes,
provided that the recipient has accepted such information subject to a
confidentiality agreement substantially similar to this Section 11.14. For
purposes of the foregoing, "confidential information" shall mean any information
respecting Borrower or its Subsidiaries reasonably considered by Borrower to be
confidential, other than (i) information previously filed with any Governmental
Agency and available to the public, (ii) information previously published in any
public medium from a source other than, directly or indirectly, that Lender, and
(iii) information previously disclosed by Borrower to any Person not associated
with Borrower which does not owe a professional duty of confidentiality to
Borrower or which has not executed an appropriate confidentiality agreement with
Borrower. Nothing in this Section shall be construed to create or give rise to
any fiduciary duty on the part of the Administrative Agent or the Lenders to
Borrower.

            11.15 Further Assurances. Borrower shall, at its expense and without
expense to the Lenders or the Administrative Agent, do, execute and deliver such
further acts and documents as the Requisite Lenders or the Administrative Agent
from time to time reasonably require for the assuring and confirming unto the
Lenders or the Administrative Agent of the rights hereby created or intended now
or hereafter so to be, or for carrying out the intention or facilitating the
performance of the terms of any Loan Document.

            11.16 Integration. This Agreement, together with the other Loan
Documents and the letter agreement referred to in Section 3.2, comprises the
complete and integrated agreement of the parties on the subject matter hereof
and supersedes all prior agreements (including the commitment letter between the
Arranger, Bank of America and Borrower dated June 15, 1999), written or oral, on
the subject matter hereof. In the event of any conflict between the provisions
of this Agreement and those of any other Loan Document, the provisions of this
Agreement shall control and govern; provided that the inclusion of supplemental
rights or remedies in favor of the Administrative Agent or the Lenders in any
other Loan Document shall not be deemed a conflict with this Agreement. Each
Loan Document was drafted with the joint participation of the respective parties
thereto and shall be construed neither against nor in favor of any party, but
rather in accordance with the fair meaning thereof.

            11.17 Governing Law. Except to the extent otherwise provided
therein, each Loan Document shall be governed by, and construed and enforced in
accordance with, the Laws of New York applicable to contracts made and performed
in New York.

            11.18 Severability of Provisions. Any provision in any Loan Document
that is held to be inoperative, unenforceable or invalid as to any party or in
any jurisdiction shall, as to that party or jurisdiction, be inoperative,
unenforceable or invalid without affecting the remaining provisions or the
operation, enforceability or validity of that provision as to any other party or
in any other jurisdiction, and to this end the provisions of all Loan Documents
are declared to be severable.

            11.19 Headings. Article and Section headings in this Agreement and
the other Loan Documents are included for convenience of reference only and are
not part of this Agreement or the other Loan Documents for any other purpose.

            11.20 Time of the Essence. Time is of the essence of the Loan
Documents.

            11.21 Foreign Lenders and Participants. Each Lender organized under
the Laws of a jurisdiction outside the United States of America or a State
thereof or the District of Columbia on or prior to the date of execution and
delivery of this Agreement (a) shall provide each of the Administrative Agent
and Borrower with two original and duly completed United States Internal Revenue
Forms 1001 or 4224, or successor applicable form, as appropriate, and any other
forms or certifications prescribed by the Internal Revenue Service (including a
Form W-8 or Form W-9, as appropriate) certifying that such Lender (i) is exempt
from or entitled to a reduced rate of withholding with respect to United States
federal income tax imposed on any payments under this Agreement or the Notes and
(ii) is exempt from United States backup withholding tax, (b) shall provide to
the Administrative Agent and Borrower two further copies of any such form or
certification from time to time thereafter as requested in writing by Borrower
and (c) shall obtain such extensions and renewals thereof as may reasonably be
requested in writing by Borrower or the Administrative Agent. If the form
provided by a Lender at the time such Lender first becomes a party to this
Agreement indicates a withholding rate in excess of zero, withholding taxes at
such rate shall be considered excluded from Non-Excluded Taxes, and such Lender
shall not be entitled to receive any payment under this Section 11.21 with
respect thereto, unless and until such Lender provides any additional forms or
certifications certifying that a lesser rate of withholding applied with respect
to such Lender under existing Law at the time such Lender first became a party
to this Agreement, whereupon withholding tax at such lesser rate only shall be
considered excluded from









                                      -89-

<PAGE>   97



Non-Excluded Taxes for all subsequent periods. Each Person that becomes a
participant pursuant to Section 11.8 shall, upon the effectiveness of the
related transfer, be required to provide all of the forms and certifications
required pursuant to this Section 11.21, as appropriate, as if such participant
were a Lender; provided that such participant shall furnish all such required
forms and certifications to the Lender from which the related participation was
purchased.

            11.22 Hazardous Material Indemnity. Borrower hereby agrees to
indemnify, hold harmless and defend (by counsel reasonably satisfactory to the
Administrative Agent) the Administrative Agent and each of the Lenders and their
respective directors, officers, employees, agents, successors and assigns from
and against any and all claims, losses, damages, liabilities, fines, penalties,
charges, administrative and judicial proceedings and orders, judgments, remedial
action require ments, enforcement actions of any kind, and all costs and
expenses incurred in connection therewith (including but not limited to
reasonable attorneys' fees and the reasonably allocated costs of attorneys
employed by the Administrative Agent or any Lender, and expenses to the extent
that the defense of any such action has not been assumed by Borrower), arising
directly or indirectly out of (i) the presence on, in, under or about any Real
Property of any Hazardous Materials, or any releases or discharges of any
Hazardous Materials on, under or from any Real Property and (ii) any activity
carried on or undertaken on or off any Real Property by Borrower or any of its
predecessors in title, whether prior to or during the term of this Agreement,
and whether by Borrower or any predecessor in title or any employees, agents,
contractors or subcontractors of Borrower or any predecessor in title, in
connection with the handling, treatment, removal, storage, decontamination,
clean-up, transport or disposal of any Hazardous Materials at any time located
or present on, in, under or about any Real Property. The foregoing indemnity
shall further apply to any residual contamination on, in, under or about any
Real Property, or affecting any natural resources, and to any contamination of
any Property or natural resources arising in connection with the generation,
use, handling, storage, transport or disposal of any such Hazardous Materials,
and irrespective of whether any of such activities were or will be undertaken in
accordance with applicable Laws, but the foregoing indemnity shall not apply to
Hazardous Materials on any Real Property, the presence of which is caused by the
Administrative Agent or the Lenders. Borrower hereby acknowledges and agrees
that, notwithstanding any other provision of this Agreement or any of the other
Loan Documents to the contrary, the obligations of Borrower under this Section
shall be unlimited corporate obligations of Borrower and shall not be secured by
any Lien on any Real Property. Any obligation or liability of Borrower to any
Indemnitee under this Section 11.22 shall survive the expiration or termination
of this Agreement

Obligations owed to the Lenders.

            11.23 Waiver of Right to Trial by Jury. EACH PARTY TO THIS AGREEMENT
HEREBY EXPRESSLY WAIVES ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION
OR CAUSE OF ACTION ARISING UNDER ANY LOAN DOCUMENT OR IN ANY WAY CONNECTED WITH
OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTY HERETO OR ANY OF THEM WITH
RESPECT TO ANY LOAN DOCUMENT, OR THE TRANSACTIONS RELATED THERETO, IN EACH CASE
WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR
TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES AND CONSENTS THAT ANY SUCH
CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT
A JURY, AND THAT ANY PARTY TO THIS AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR
A COPY OF THIS SECTION WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE
SIGNATORIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

            11.24 Purported Oral Amendments. BORROWER EXPRESSLY ACKNOWLEDGES
THAT THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS MAY ONLY BE AMENDED OR
MODIFIED, OR THE PROVISIONS HEREOF OR THEREOF WAIVED OR SUPPLEMENTED, BY AN
INSTRUMENT IN WRITING THAT COMPLIES WITH SECTION 11.2. BORROWER AGREES THAT IT
WILL NOT RELY ON ANY COURSE OF DEALING, COURSE OF PERFORMANCE, OR ORAL OR
WRITTEN STATEMENTS BY ANY REPRESENTATIVE OF THE MANAGING AGENT OR ANY BANK THAT
DOES NOT COMPLY WITH SECTION 11.2 TO EFFECT AN

                                                               AMENDMENT NO. 012


     AMENDMENT NO. 012, dated as of March 4, 1999, to Contract No.
DE-AC01-93NE50067, 08843672/50067-02 entered into January 14, 1994 (the
"Contract") by and between United States Enrichment Corporation ("USEC"),
Executive Agent of the United States of America, and AO Techsnabexport
("TENEX"), Executive Agent of the Ministry of Atomic Energy (MINATOM), Executive
Agent of the Russian Federation. Capitalized terms used but not defined herein
shall have the meaning ascribed to such terms in the Contract.

     WHEREAS, the parties acknowledge that TENEX will enter into an agreement
(the "DOE Agreement") with the U.S. Department of Energy ("DOE") under which
TENEX shall transfer the natural uranium associated with deliveries ordered for
calendar years 1997 and 1998 under the Contract and DOE will pay TENEX for such
material in several payments (the "DOE Payments");

     WHEREAS, to facilitate the delivery of UF(6nat) to TENEX pursuant to
Amendment No. 8 to the Contract, USEC has been required and will in the future
be required to provide cylinders for such UF(6nat), and the parties wish to
compensate USEC for such cylinder costs;

     WHEREAS, in June 1998 USEC provided a delivery order to TENEX that was not
executed for material to be delivered in calendar year 1999 (the "CY99 Order"),
and prior to June 1, 1999 the parties intend to revise the delivery schedule for
that order because certain shipments scheduled for delivery in calendar year
1998 were delayed;

     WHEREAS, the parties additionally wish to provide for the replacement of a
cylinder of LEU shipped to the United States in 1997;

     NOW, THEREFORE, USEC and TENEX agree as follows:

     SECTION 1. Part I, Section H.27 of the Contract is hereby amended by adding
the following to the end of paragraph (f) thereof:

     "For example, prior to the issuance by USEC of the delivery order for each
     calendar year, TENEX and USEC shall agree upon arrangements for cylinders
     (including, if TENEX requests USEC to arrange for cylinders, an amount to
     be paid to USEC and the manner of payment) required for the delivery of
     UF(6nat) to TENEX in respect of LEU shipments for that calendar year
     (regardless of when such shipments actually occur). If it is subsequently
     determined that a greater or lesser number of cylinders is required for a
     calendar year, the cylinder charges for the following year shall be
     increased or reduced accordingly. The agreement on storage pursuant to
     subsection (a)(i) above shall define the terms and conditions, including
     warranties, that will apply to specific cylinders delivered to TENEX and to
     the return of the cylinders when no longer required. Absent advance notice
     to the contrary from a party, it will be assumed that a transfer of
     UF(6nat) to a third party includes the applicable cylinder."

<PAGE>   2


     SECTION 2. (a) With respect to delivery orders for calendar years 1997 and
1998, the cylinder charges shall be $3,273,550 based on a per cylinder charge of
$2,350 per cylinder for 1,393 48G cylinders. Subsequent to TENEX and DOE
entering into the DOE Agreement, TENEX shall pay these charges to USEC in
installments each payable within 10 days after TENEX receives a DOE Payment.
Each installment payment shall be equal to the product of the number of
cylinders of material associated with the DOE Payment multiplied by $2,350, with
the understanding that TENEX shall have paid USEC the entire amount due under
this paragraph no later than 10 days after TENEX has received all of the DOE
Payments under the DOE Agreement.

     (b) With respect to the CY99 Order, the parties recognize that (i) in order
to ensure uninterrupted implementation of deliveries under the Contract and
taking into account the significant lead times necessary to obtain cylinders,
USEC has previously purchased cylinders to hold the natural uranium component of
the CY99 Order and (ii) TENEX is currently arranging for the disposition of the
natural uranium component of such material. Once TENEX has completed such
arrangements, the parties shall agree on a revised delivery schedule for the
CY99 Order. Subsequent to agreement on a revised schedule for delivery of the
CY99 Order, TENEX shall be responsible for reimbursing or arranging for a third
party to reimburse USEC for the cylinder charges associated with the CY99 Order.
The cylinder charges associated with the CY99 Order shall be $7,975,000 based on
a per cylinder charge of $5,500 per cylinder for 1,450 48X cylinders. TENEX
shall satisfy this responsibility by paying or arranging for a third party to
pay USEC, within 70 days of title transfer under Section H.27 of the Contract to
UF(6nat) associated with LEU delivered to USEC under the CY99 Order, an amount
equal to the percentage of $7,975,000 that equals the percentage such UF(6nat)
constitutes of the total UF(6nat) associated with the CY99 Order. In any event,
USEC shall have received the entire $7,975,000 due under this paragraph no later
than 70 days after title transfer on the last shipment of material in
satisfaction of the CY99 Order.

     (c) Payments to USEC shall be in U.S. currency either by wire transfer to
an account to be named in writing by USEC or in accordance with other
arrangements agreed to in writing by the parties. USEC shall be entitled to
credit any amount that is not paid when due hereunder against any TENEX invoice
for SWU delivered to USEC. In the event that TENEX fails to make any delivery of
material in accordance with the delivery schedule agreed to between the parties,
then USEC shall be entitled to credit all outstanding cylinder charges at such
time against any amounts owed by USEC until such charges have been reimbursed in
full. Prior to exercising its right to credit under this paragraph, USEC shall
provide 30 days notice to TENEX and will consult with TENEX during this period.
This provision and the rights hereunder shall be reciprocal.

     SECTION 3. TENEX shall replace the LEU delivered in 1997 in cylinder LU0846
with 1519.225 KgU of LEU enriched to an assay of 4.95% and containing the
equivalent of 10,788.017 separative work units and 17,188.512 KgU of UF(6nat).
Unless otherwise agreed, this replacement LEU shall be delivered in cylinder
LU1413, which shall be included with the LEU shipments to be made in calendar
year 1999 in respect of the remaining calendar year 1998 shipments. The
replacement LEU shall be subject to the inspection and acceptance procedures in
the Contract. The price for the SWU component in the LEU in cylinder LU1413
shall correspond to the price, established for the LEU SWU component of the CY
1997 Delivery Order and shall be equal to $84-50 per SWU.
     SECTION 4. Except as amended hereby, the Contract shall remain unchanged
and in full force and effect. In the event that any conflict arises between this
Amendment and the Contract, TENEX and USEC shall resolve such conflict
consistent with the purpose of this Amendment as set forth in the recitals

the date first written above.
