PROSPECTUS SUMMARY.  Because this is a summary, it does not contain all the
information that may be important to you. You should read this entire document
before making a decision. All references in this Prospectus to "fiscal" or
"fiscal year" refer to USEC's fiscal year ended on June 30, unless the context
otherwise requires. All references to the "Company" and "USEC" mean USEC Inc., a
Delaware corporation, and its consolidated subsidiaries, unless the context
otherwise requires.

OVERVIEW OF USEC.  USEC, a global energy company, is the world leader in the
production and sale of uranium fuel enrichment services for commercial nuclear
power plants. Our market share is approximately 75% of the North American
uranium enrichment market and approximately 40% of the world market. We enrich
uranium utilizing a gaseous diffusion process at two plants located in Paducah,
Kentucky and near Portsmouth, Ohio (the "GDPs"), which are among the largest
industrial facilities in the world. Our fiscal 1998 revenue was $1.4 billion and
our pre-tax income, before special charges of $46.6 million, was $192.9 million.
Our net income before special charges on a pro forma basis (primarily to reflect
a provision for federal, state and local income taxes and interest expense) for
fiscal 1998 was $97.3 million.

USEC supplies enriched uranium to approximately 60 customers for use in
about 170 nuclear reactors located in 14 countries throughout the world.
Generally, our customer contracts are "requirements" contracts that obligate our
customers to purchase from us a specified percentage of their enriched uranium
requirements. Consequently, our annual sales are dependent upon our customers'
requirements for enrichment services, which are driven by nuclear reactor
refueling schedules, reactor maintenance schedules, customers' considerations of
costs, and regulatory actions. Based on our customers' long-term estimates of
their requirements and certain other assumptions, including our estimates of
inflation rates, at September 30, 1998 we had long-term requirements contracts
with utilities to provide uranium enrichment services aggregating $3.6 billion
through fiscal 2001 and $7.0 billion through fiscal 2009.

USEC was privatized by the U.S. Government on July 28, 1998 (the
"Privatization Date") through an initial public offering of common stock (the
"Privatization"). As a result of the Privatization, the U.S. Government no
longer holds any equity interest in the Company. Our shares are listed on the
New York Stock Exchange.

COMPANY STRATEGY.  Our goal is to continue to be the world's leading
supplier of uranium fuel enrichment services and to diversify over time into
related strategic businesses that will contribute to our growth and
profitability. To achieve this goal, we intend to focus on the following:

- Aggressively Pursue Sales Opportunities. We have implemented a strategy
designed to increase sales to existing customers and to add new customers. We
have replaced standardized contracts with flexible contract terms and increased
our attention to customer service, product quality and reliability.

- Improve Operating Efficiencies.  We plan to continue to improve operating
efficiencies and productivity by implementing and monitoring a rigorous cost
management program.

- Commercialize AVLIS Technology.  We plan to complete the development and
commence commercialization of the next generation of uranium enrichment
technology, Atomic Vapor Laser Isotope Separation or AVLIS, which uses lasers to
enrich uranium. This should permit us to remain one of the lowest cost suppliers
of uranium enrichment services and enhance our competitive position. We expect
commercial deployment of AVLIS to begin in 2005 and reach planned capacity in
2006.

COMPETITIVE ADVANTAGES.  Although we operate in a highly competitive
environment, we believe that the following factors should enable us to compete
effectively and continue as the world leader in the uranium enrichment market:

- Strong Financial Position.  Our strong financial position results from a
significant backlog of contracted services attributable to established
customers.

- Favorable Arrangements with the U.S. Government.  We are the beneficiary
of several favorable long-term arrangements with the U.S. Government,
implemented in connection with our Privatization. These arrangements include:

-- An advantageous lease providing for nominal rent payments for the GDPs
with an open term renewal option;

-- Low-cost power purchase arrangements pursuant to which we purchase a
majority of our electricity requirements (which represented 53% of production
costs in fiscal 1998) at an average cost of less than 2 cents/kWh in fiscal
1998 and 2.7 cents/kWh in the three months ended September 30, 1998; and

-- The assumption by the U.S. Government of substantially all liabilities
arising from the operation of the GDPs prior to the Privatization, including
substantially all environmental liabilities.

- AVLIS.  We have the exclusive commercial rights to the AVLIS technology
developed by the U.S. Government and believe that we have a considerable
lead-time advantage over others attempting to develop similar laser-based
uranium enrichment technology.

- Ability to Complete Sales from Natural Uranium Inventory.  We are
positioned to supplement our uranium enrichment revenue through sales of natural
uranium. Our existing inventory contains a substantial amount of natural
uranium.

- Executive Agent Under a U.S./Russia Agreement.  We are the Executive Agent
for the United States under a government-to-government agreement between the
United States and the Russian Federation. In this capacity, we purchase from
Russia the separative work unit ("SWU") component of low-enriched uranium
("LEU") derived from highly enriched uranium ("HEU") recovered from dismantled
nuclear weapons of the former Soviet Union. Although acting as U.S. Executive
Agent may pose certain risks, the arrangement provides an important strategic
opportunity for us to introduce additional uranium enrichment services from
Russia to the global market on an orderly basis and in a competitive manner that
ensures the reliability and continuity of supply to enrichment customers.

THE URANIUM ENRICHMENT MARKET.  The demand for uranium enrichment services
is a function of the number of nuclear reactors using enriched uranium fuel and
their fuel requirements. Nuclear power accounts for 18% of the domestic and 17%
of the world-wide production of electricity. As of September 30, 1998, there
were 106 utilities operating 377 nuclear power reactors that use enriched
uranium for fuel, including 104 reactors in the United States.

We anticipate the world demand for enrichment services to be relatively
stable or increase slightly over the next 10 to 15 years. We believe that the
nuclear power market in the U.S. and Western Europe may decline slightly over
the next 10 to 15 years, counter-balanced by an expected increase in the Asian
market during the same period. We also anticipate that increases in demand from
new reactors expected to come on-line, as well as increased utilization at
existing reactors, will offset decreases in demand from reactors that cease
operations during this period. Globally, uranium enrichment is provided by four
major suppliers, including USEC.

OUR HISTORY.  For approximately 40 years, the U.S. Department of Energy
("DOE") and its predecessors managed the U.S. Government's uranium enrichment
operations. USEC was established by the Energy Policy Act of 1992 as a
wholly-owned government corporation. This transfer to a government-owned
corporation was intended to enable us to operate like a private sector business
in preparation for our eventual Privatization, which was completed on July 28,
1998.

(1) Gives effect to the Company's initial public offering (the "IPO"), interest
expense on borrowings of $550.0 million incurred at the time of the IPO, and
the Company's transition to taxable status, as if such events had occurred
at the beginning of fiscal 1998.

(2) Special charges amounted to $46.6 million ($28.9 million net of income taxes
on a pro forma basis) for fiscal 1998 for costs related to the Privatization
and certain severance and transition benefits to be paid to GDP workers in
connection with workforce reductions over the next two years.

(3) Pro forma interest expense of $36.0 million is based on a weighted average
interest rate of 6.6%, including the amortization of fees, on $550.0 million
of borrowings incurred at the time of the IPO, as if such borrowings had
occurred at the beginning of fiscal 1998.

(4) The Company was exempt from federal, state and local income taxes until the
IPO. The pro forma provision for income taxes of $41.9 million is based on
an effective income tax rate of 38% and assumes the IPO had occurred at the
beginning of fiscal 1998.

(5) On a pro forma basis, net income before special charges for fiscal 1998 was
$97.3 million or $.97 per share.

(6) At the time of the IPO, the Company became subject to federal, state and
local income taxes. The provision for income taxes includes a special income
tax benefit of $54.5 million for deferred income tax benefits that arise
from the Company's transition to taxable status. Deferred tax benefits
represent differences between the carrying amounts for financial reporting
purposes and the Company's estimate of the tax bases of its assets and
liabilities.

Excluding the special tax benefit, the provision for income taxes for the
first fiscal quarter ended September 30, 1998, amounted to $6.3 million.

(7) Excluding the special tax benefit, net income was $8.6 million or $.09 per
share.

RISK FACTORS.  You should consider carefully the following risk factors in
addition to the more-detailed information contained in this Prospectus.

HOLDING COMPANY STRUCTURE

Our operations are conducted primarily through our subsidiaries and,
therefore, we are dependent upon cash flow from that entity to meet our
obligations. Our subsidiaries will have no direct obligation to pay amounts due
on the Senior Notes and will not guarantee the Senior Notes. As a result, the
Senior Notes effectively will be subordinated to all existing and future
third-party indebtedness and other liabilities of our subsidiaries (including
trade payables). Any rights of the Company and its creditors, including the
holders of Senior Notes, to participate in the assets of any of the Company's
subsidiaries upon any liquidation or reorganization of any such subsidiary will
be subject to the prior claims of that subsidiary's creditors (including trade
creditors). The Indenture governing the Senior Notes does not limit the
Company's or its subsidiaries' ability to incur additional indebtedness in the
future.

VARIABILITY OF REVENUES AND OPERATING RESULTS

Our 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, we provide customers a window
ranging from 10 to 30 days to take delivery of ordered product. Refueling orders
typically average $14.0 million per customer order for our uranium enrichment
services.

We plan our cash outlays for power and other production costs, a significant
portion of which is fixed in the short-term, on the basis of meeting customer
orders and achieving revenue targets for the year. As a result, a relatively
small change in the timing of customer orders may cause earnings and cash flow
results to be substantially above or below expectations.

While the Company does not anticipate making significant natural uranium
sales until after fiscal 2000, there can be no assurance that the Company will
be able to sell such natural uranium at anticipated prices and quantities.

ELECTRICITY

The GDPs require substantial amounts of electricity to enrich uranium,
representing 53% of production costs in fiscal 1998. We purchase firm,
supplemental firm and non-firm power to meet our production needs. While almost
all of the power purchased for the Portsmouth GDP is favorably-priced firm
power, a substantial portion of the power supplied to the Paducah GDP is
supplemental firm or non-firm power which must be purchased at market-based
rates. During certain periods, including the summer months when power costs are
typically higher, almost all of the power supplied to the Paducah GDP must be
purchased at market-based rates. Our production costs increase to the extent
that the cost of firm power, which represented 71% of our fiscal 1998 power
needs, and the market-based prices of supplemental firm and non-firm power,
which represented 29% of our fiscal 1998 power needs, rise.

When our costs of supplemental firm and non-firm power are high, we may
reduce our production of SWU at the GDPs. However, operating the GDPs at the
lower production levels results in higher unit production costs per SWU which
may adversely affect our profitability. In addition, an unanticipated
interruption to the power supply to the GDPs could have a material adverse
effect on the Company's financial condition to the extent we have to curtail
operations for any length of time.

Persistent hot weather, high electricity demand in the Midwest and power
generation shortages resulted in record-high power costs nationally from early
last summer into the fall, with a resulting negative impact on the Paducah GDP's
production costs. For additional information on how the market prices for power
in the first quarter ended September 30, 1998 are expected to negatively impact
our fiscal year 1999 financial results, see "Management's Discussion and
Analysis of Financial Condition and Results of Operations."

The Company is exploring a number of

8

10

alternatives to reduce its exposure to market-priced power at the Paducah GDP
during next summer and future periods, including negotiations to procure power
at acceptable prices and reducing production levels at the Paducah GDP during
affected periods. There can be no assurance that the Company will be successful
in reducing such exposure, including through the procurement of power at
acceptable prices to economically operate the Paducah GDP during the affected
periods.

Upon termination of the power contracts, we are responsible for our pro rata
share of costs of future decommissioning, shutdown and demolition activities for
three coal-fired generating plants. Estimated costs are accrued over the
contract period, and the accrued liability amounted to $18.2 million at
September 30, 1998. It is possible that our pro rata share of total costs for
such decommissioning and shutdown activities will exceed the amounts that we
have accrued.

RISKS ASSOCIATED WITH ENRICHMENT OPERATIONS

Use of Chemicals in Enrichment.  USEC's operations at the GDPs involve
processes that use many different toxic chemicals in significant quantities. We
follow strict procedures and precautions in the handling, storage and
transportation of the materials we use in our operations, and we have not had
any significant releases into the environment. Nevertheless, if an accident were
to occur, the volume of the release and the speed of corrective action taken by
GDP workers, and other factors beyond USEC's control, such as weather and wind
conditions, could significantly affect the severity of the accident. The primary
risk posed by such releases is to humans or animals in close proximity to the
releases.

Dependence on Large Production Facilities. USEC's operations are subject to
the typical risks inherent in operating large scale production facilities.
Significant or extended unscheduled downtime at either GDP due to the following
could adversely affect our operations and financial condition:

-  Equipment breakdowns
-  Power interruptions
-  Regulatory enforcement actions (including any by the Nuclear Regulatory
Commission (the "NRC"))
-  Labor disruptions
-  Interruptions caused by potential natural or other disasters (including
earthquake activity in the vicinity of the Paducah GDP)

Contractual Commitment to Operate the GDPs. In an agreement with the U.S.
Treasury (the "Treasury Agreement"), we committed to operate both of the GDPs
until January 1, 2005, subject only to limited exceptions, including events
beyond our control such as fires, floods and other acts of God, maintenance of
certain financial ratios, a significant reduction in the worldwide demand for
SWU, a significant reduction in the average price for SWU, or a significant
decrease in operating margins, among others. It is possible that our commitment
to continue operations at both GDPs may adversely affect our financial
performance if the supply of SWU from other sources increases.

RELIANCE ON NUCLEAR UTILITY INDUSTRY; CUSTOMER CONCENTRATION

Our future prospects in the uranium enrichment business are tied directly to
the nuclear utility industry world-wide. Events that could adversely affect us
by eliminating or reducing requirements, suspending or reducing reactor
operations or canceling new reactor construction include:

-  Customers' business decisions concerning reactors or reactor operations
-  Regulatory actions or changes in regulations by nuclear regulatory bodies
-  Accidents or civic opposition to nuclear operations

In fiscal 1998, our 10 largest customers represented 44% of our revenue. A
termination or reduction of the nuclear fuel needs of any of our major customers
could adversely affect our financial performance. Further, the inability of a
major customer to make timely payments could also adversely affect our financial
performance.

COMPETITION; TREND TOWARD LOWER PRICING

Competition.  In the highly competitive global uranium enrichment industry,
we compete with three other major producers: AO Techsnabexport ("Tenex"), a
Russian government entity; Eurodif/ Cogema ("Eurodif"), a consortium controlled
by the French government; and Urenco, a consortium of the British and Dutch
governments and private

9

11

German corporations. Our competitors may have
greater financial resources and receive other types of support from their
respective governmental owners which enable them to be less cost sensitive. In
addition, our competitors' decisions may be influenced by political and economic
policy considerations rather than prevailing market conditions. Further,
purchasers in certain areas (particularly Europe and the countries comprising
the former Soviet Union) may favor their local producers, due to government
influence or national loyalties.

Trend Toward Lower Pricing.  Changes in the market price of SWU can
significantly affect our profitability. Factors influencing such changes
include:

-  Industry overcapacity
-  Excess inventory at customer facilities
-  Global demand
-  New technologies
-  Production costs of other enrichment suppliers
-  Exchange rate fluctuations relating to the U.S. dollar versus
competitors' currencies

Currently, there is an excess of production capacity and certain suppliers
have announced plans to expand their capacities. Overcapacity, coupled with
sales of buyer-held inventory, and exports of enriched uranium from the
countries comprising the former Soviet Union have, over the last several years,
resulted in significant downward pressure on prices. Accordingly, our new
contracts have significantly lower prices per SWU and substantially shorter
terms than previous contracts. Further, we anticipate a trend toward somewhat
lower prices, which may adversely affect our financial performance, to continue
as we compete for new business.

RISKS ASSOCIATED WITH PURCHASES UNDER THE RUSSIAN HEU CONTRACT

In January 1994, USEC entered into a 20-year contract to purchase SWU from
Tenex (the "Russian HEU Contract"). As the volume of SWU purchased under the
Russian HEU Contract increases, we operate the GDPs at lower production levels
resulting in higher unit production costs. Our objective is to manage our
production and inventory levels (including anticipated purchases under the
Russian HEU Contract) in a manner that most efficiently meets customer demand
for enrichment services. Deliveries by Tenex have been delayed from time to time
and a portion of 1998 deliveries are currently delayed. To date, our ability to
fill customer orders has not been disrupted due to our existing inventory.
However, an unanticipated significant delay in deliveries of Russian SWU, or
deliveries of SWU not meeting commercial specifications, could require unplanned
adjustments to production levels at the GDPs, and could adversely impact our
profitability.

The mechanism for establishing SWU prices under the Russian HEU Contract for
purchases through 2001 has been set, and we expect the prices to be
substantially higher than our marginal cost of producing SWU at the GDPs.
Consequently, although we presently can resell the Russian SWU for more than its
cost to us, such sales are less profitable than sales of SWU produced at the
GDPs. The effect of this pricing structure will become more pronounced if the
market price for SWU declines further, and it is possible that the price we pay
for the Russian SWU may exceed the price at which we can resell the material.

Under an agreement with the U.S. Department of State and DOE, we can be
terminated, or resign, as the U.S. Executive Agent, or additional executive
agents may be named. In either event, any new executive agent could represent a
significant new competitor that could adversely affect our market share and
profitability.

AVLIS

New Technology.  There are a number of risks associated with the development
and commercialization of AVLIS, a new laser-based uranium enrichment technology,
any of which could adversely affect our financial or competitive position.
Before we will be in a position to finalize our decision to construct a
full-scale commercial facility, we need to conduct additional equipment
demonstration and testing activities. We could encounter unanticipated delays or
expenditures at this stage. If we determine not to proceed with AVLIS
deployment, we would pursue other options for enrichment services such as GDP
upgrades or exploring other new technologies, which could adversely affect our
financial or competitive position. In addition, we could incur

10

12

certain additional costs in connection with terminating the AVLIS project. If we
determine to deploy AVLIS, we cannot provide assurance that we could complete an
AVLIS plant as scheduled or that a full-scale facility will operate at its
design capacity.

Costs/Financing.  In September 1997, based on preliminary design drawings
and assumptions regarding the suitability of available sites, we estimated AVLIS
development and deployment to cost approximately $2.2 billion until commercial
deployment, which is expected to begin in fiscal 2005. We periodically
re-evaluate our AVLIS estimated costs and currently believe this estimate could
vary by up to 20%. If we determine to deploy AVLIS, it is possible that
development costs or construction costs associated with AVLIS could be higher
than anticipated. We will require significant financing to achieve commercial
deployment of AVLIS. We cannot provide assurance that financing will be
available when required, and we cannot predict the cost or terms of such
financing.

REGULATORY AND ENVIRONMENTAL RISKS

We are subject to certain government regulation. See
"Business -- Regulatory Oversight." In particular, the NRC regulates the GDPs
under the Atomic Energy Act. If the NRC were to find that we had not complied
with its requirements, it could take actions or impose conditions which could
adversely affect our financial condition. See "Business -- Regulatory
Oversight -- NRC." Our operations are also subject to numerous federal, state
and local laws and regulations relating to the protection of health, safety and
the environment, including those regulating the emission and discharge into the
environment of materials (including radioactive materials). See
"Business -- Environmental Matters." Unanticipated events or regulatory
developments related to environmental matters could have a material adverse
effect on our financial condition.

POSSIBLE ILLIQUIDITY OF THE SECONDARY MARKET

It is not possible to predict how the Senior Notes will trade in the
secondary market or whether such market will be liquid or illiquid. There is
currently no secondary market for the Senior Notes. The Underwriters have
advised us that they intend, but are not obligated, to make a market in the
Senior Notes. We cannot assure that a secondary market will develop, or, if a
secondary market does develop, that it will provide the holders of Senior Notes
with liquidity or that it will continue for the life of the Senior Notes.

FORWARD-LOOKING STATEMENTS

This Prospectus contains certain forward-looking statements. You will find
discussions containing forward-looking statements in this "Risk Factors" section

of Operations" and "Business" sections, as well as within this Prospectus
generally. In addition, our use of the words "believes," "intends,"
"anticipates," "expects" and words of similar import may constitute "forward-
looking statements." Because such statements involve risks and uncertainties,
our actual results may differ materially from those we express or imply by such
forward-looking statements.

RATIO OF EARNINGS TO FIXED CHARGES

Prior to the IPO, the Company had no debt. Giving effect to bank debt
incurred in connection with the IPO, the pro forma ratio of earnings to fixed
charges for fiscal 1998 was 3.9x. The ratio of earnings to fixed charges for the
three months ended September 30, 1998, was 3.1x.

For purposes of calculating the ratio of earnings to fixed charges,
earnings represent income before income taxes plus fixed charges, and fixed
charges represent interest expense, amortization of fees, capitalized interest
and the interest component of leases.

USE OF PROCEEDS

In connection with the Privatization, the Company entered into a credit
facility comprised of three tranches (the "Credit Facility"). USEC will use the
net proceeds from the sale of the Senior Notes to repay borrowings under the
Credit Facility which totaled $565.0 million at September 30, 1998. The weighted
average interest rate for borrowings under the Credit Facility, including the
amortization of fees, amounted to 6.8% for the period ended September 30, 1998.

A portion of the indebtedness to be repaid under the Credit Facility is owed
to Morgan Guaranty Trust Company of New York ("Morgan Guaranty"), a lender under
the Credit Facility. Morgan Guaranty, a wholly owned subsidiary of J.P. Morgan &
Co. Incorporated, is an affiliate of J.P. Morgan Securities Inc., an underwriter
of this offering.

CAPITALIZATION

The following table sets forth the capitalization of the Company as of
September 30, 1998. This table should be read in conjunction with the Company's

(1) Gives effect to the IPO, interest expense on borrowings of $550.0 million
incurred at the time of the IPO, and the Company's transition to taxable
status, as if such events had occurred at the beginning of fiscal 1998.

(2) Special charges amounted to $46.6 million ($28.9 million net of income taxes
on a pro forma basis) for fiscal 1998 for costs related to the Privatization
and certain severance and transition benefits to be paid to GDP workers in
connection with workforce reductions over the next two years.

(3) Pro forma interest expense of $36.0 million is based on a weighted average
interest rate of 6.6%, including the amortization of fees, on $550.0 million
of borrowings incurred at the time of the IPO, as if such borrowings had
occurred at the beginning of fiscal 1998.

(4) The Company was exempt from federal, state and local income taxes until the
IPO. The pro forma provision for income taxes of $41.9 million is based on
an effective income tax rate of 38% and assumes the IPO had occurred at the
beginning of fiscal 1998.

(5) On a pro forma basis, net income before special charges for fiscal 1998 was
$97.3 million or $.97 per share.

(6) At the time of the IPO, the Company became subject to federal, state and
local income taxes. The provision for income taxes includes a special income
tax benefit of $54.5 million for deferred income tax benefits that arise
from the Company's transition to taxable status. Deferred tax benefits
represent differences between the carrying amounts for financial reporting
purposes and the Company's estimate of the tax bases of its assets and
liabilities.

Excluding the special tax benefit, the provision for income taxes for the
first fiscal quarter ended September 30, 1998, amounted to $6.3 million.

(7) Excluding the special tax benefit, net income was $8.6 million or $.09 per
share.

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 Financial Statements and notes
thereto appearing elsewhere in this Prospectus.

OVERVIEW

USEC, a global energy company, is the world leader in the production and
sale of uranium fuel enrichment services for commercial nuclear power plants,
with approximately 75% of the North American market and approximately 40% of the
world market. Uranium enrichment is a critical step in transforming natural
uranium into fuel for nuclear reactors to produce electricity. Based on
customers' long-term estimates of their requirements and certain other
assumptions, including the Company's estimates of inflation rates, at September
30, 1998 the Company had long-term requirements contracts with utilities to
provide uranium enrichment services aggregating $3.6 billion through fiscal 2001
and $7.0 billion through fiscal 2009.

The Company is the Executive Agent of the U.S. Government under a
government-to-government agreement to purchase SWU recovered from dismantled
nuclear weapons from the former Soviet Union for use in commercial electricity
production. The Company's cost of sales has been, and will continue to be,
adversely affected by amounts paid to purchase SWU under the Russian HEU
Contract at prices that are substantially higher than its marginal production
cost at the GDPs. As the volume of Russian SWU purchases has increased, the
Company has operated the GDPs at lower production levels resulting in higher
unit production costs. Pursuant to the Russian HEU Contract, Russian SWU
purchases will peak in calendar year 1999 at 5.5 million SWU per year and are
expected to remain at that level thereafter.

The Company's 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. The stated term of contracts transferred by DOE to
the Company on July 1, 1993 (the "Transition Date") is 30 years, although future
purchase obligations thereunder may be terminated by, among other things, giving
10 years' notice, although the Company has allowed shorter notice periods. The
terms of newer contracts entered into by the Company since the Transition Date
range from 3 to 11 years and do not typically provide for advance termination
rights. Revenue from sales of SWU under new contracts represented 68% of total
revenue in fiscal 1998. The Company believes that the trend for contracts with
shorter terms will continue, with the newer contracts generally containing terms
in the range of 3 to 7 years.

The Company's 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 a window
ranging 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. Refueling orders typically average $14.0 million per
customer order for the Company's uranium enrichment services. The Company plans
its cash outlays for power and other production costs, a significant portion of
which is fixed in the short term, on the basis of meeting customer orders and
achieving revenue targets for the year. As a result, a relatively small change
in the timing of customer orders may cause earnings and cash flow results to be
substantially above or below expectations. Notwithstanding this variability, the
Company has significant backlog based on customers' estimates of their
requirements for uranium enrichment services.

The financial statements, discussed below, are not necessarily indicative of
the results of operations and financial position in the future or what the
results of operations and financial position would have been had the Company
been a private sector stand-alone entity during the periods presented.

Revenue.  Substantially all of the Company'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, virtually all of
the Company'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
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. The Company 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.

Revenue could be negatively impacted by NRC actions suspending operations at
domestic reactors under contract with the Company. 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 the Company.

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

The Company's financial performance over time can also be significantly
affected by changes in the market price for SWU. SWU prices have been declining,
reflecting the trend toward lower prices and shorter contracts in the highly
competitive uranium enrichment market and the impact of changes in foreign
currency exchange rates. The Company believes that its willingness to provide
flexible contract terms has been instrumental in its ability to successfully
compete for and capture open demand. The Company also believes that the advent
of shorter contract terms is an industry wide phenomenon; utilities have been
experiencing rapid changes in their industry and have been less willing to enter
into extended obligations. This trend toward shorter contract terms requires
that the Company, as well as its competitors, pursue new sales with greater
frequency. The general effect of this is to increase the level of competition
among uranium enrichment suppliers for new SWU commitments.

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 GDPs and SWU purchase
costs (the latter mainly under the Russian HEU Contract). Production costs at
the GDPs for fiscal 1998 included purchased electric power (53% of production
costs, of which 29% represents non-firm power and 71% represents firm power),
labor and benefits (30% of production costs), depleted UF(6) disposition costs
(7% of production costs), materials, maintenance and repairs, and other costs
(10% of production costs). Since the Company uses the monthly moving average
inventory cost method, an increase or decrease in production or purchase costs
would have an effect on cost of sales over future fiscal periods. The Company's
purchases of SWU under the Russian HEU Contract are recorded at acquisition cost
plus related shipping costs.

Under its electric power supply arrangements, the Company purchases a
significant portion of its electric power at or below market rates based on
long-term contracts with dedicated power generating facilities. In fiscal 1998,
the Company's average price of electricity was $19.66 per megawatt hour ("MWh").
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.

The Company has an operations and maintenance contract with Lockheed Martin
Utility Services, Inc. ("LMUS"), a subsidiary of Lockheed Martin Corporation
(the "LMUS Contract"), under which LMUS provides labor, services, and materials
and supplies to operate and maintain the GDPs, and for which the Company pays
LMUS for its actual costs and contract fees. The LMUS Contract expires on
October 1, 2000, and may be terminated by the Company without penalty upon six
months' notice.

The Company accrues estimated costs for the future disposition of depleted
UF(6) generated as a result of its operations. Costs are dependent upon the
volume of depleted UF(6) generated and estimated conversion and disposal costs.
The Company stores depleted UF(6) at the GDPs and continues to evaluate various
proposals for its disposition. Pursuant to the USEC Privatization Act (the
"Privatization Act") and an agreement with DOE dated May 18, 1998, depleted
UF(6) generated by the Company through the date of the IPO was transferred to
DOE. In June 1998, the Company paid $50.0 million to DOE, and DOE assumed
responsibility for disposal of a certain amount of depleted UF(6) generated by
the Company from its operations at the GDPs from October 1998 to 2005.

The Company leases the GDPs and process-related machinery and equipment at
attractive, below-market 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 GDPs. Lease turnover costs are
accrued over the estimated term of the Lease Agreement which is estimated to
extend until 2005. Pursuant to the Energy Policy Act and the Privatization Act,
with certain exceptions, the U.S. Government is responsible for all
environmental liabilities associated with the operation of the GDPs prior to the
time of the IPO and decontamination and decommissioning of the GDPs at the end
of their operating lives.

The Company expects to incur additional production costs of $14.8 million in
fiscal 1999 for taxes other than income taxes and property insurance premiums.

As Executive Agent under the Russian HEU Contract, the Company has committed
to purchase 4.4 million SWU in calendar 1998, of which 1.9 million SWU in the
amount of $164.8 million was purchased as of September 30, 1998. In each of
calendar years 1999 to 2001, the Company has committed to purchase 5.5 million
SWU at the annual amount of $469.8 million, subject to certain purchase price
adjustments for U.S. inflation. The Russian HEU Contract has a 20-year term; the
Company expects its purchases after 2001 to remain at the 5.5 million SWU per
year level.

Project Development Costs.  The Company is managing the development and
engineering necessary to commercialize AVLIS, including activities relating to:

- site selection;

- NRC licensing;

- uranium feed and product technology;

- AVLIS demonstration facilities; and

- development and design of plant production facilities.

AVLIS project development costs are charged against income as incurred. The
Company intends to capitalize AVLIS development costs associated with facilities
and equipment designed for commercial production activities.

In addition, the Company has been evaluating a potential new advanced
enrichment technology called "SILEX" and plans to continue evaluating the SILEX
technology during fiscal 1999.

Selling, General and Administrative.  Selling, general and administrative
expenses include salaries and related overhead for the Company's personnel,
legal and consulting fees and other administrative costs.

Income Taxes.  With the completion of the IPO, the Company has become
subject to federal and state income taxes at a combined effective income tax
rate of 38%.

RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED SEPTEMBER 30, 1997 AND 1998

Revenue.  Revenue amounted to $307.9 million in the first fiscal quarter
ended September 30, 1998, a reduction of $132.5 million (or 30%) from $440.4
million in the first quarter of fiscal 1998. The lower revenue was attributable
primarily to 28% lower sales of SWU resulting mainly from changes in the timing
of customer nuclear reactor refueling orders. Revenue was also affected by lower
sales of natural uranium and a lower commitment level of a domestic customer.
The Company provided enrichment services for 24 reactors as compared with 32
reactors in the first quarter of fiscal 1998. The average SWU price billed to
customers during the first quarter of fiscal 1999 was about the same as in the
first quarter of fiscal 1998, notwithstanding the trend toward lower prices for
new contracts in the highly competitive uranium enrichment market.

Revenue from sales of SWU in the first quarter of fiscal 1999 was reduced
by price adjustments following a downward revision by the U.S. Department of
Commerce in its inflation index. Prices under a majority of the Company's
contracts with its customers include an inflation adjustment factor. In
September 1998, the Department of Commerce revised the inflation index downward
retroactive to 1995. The revised lower inflation rates are expected to reduce
revenue over the remainder of fiscal 1999 as well as future fiscal years.

The percentage of revenue attributed to domestic and international
customers follows:

Revenue from domestic customers declined $142.8 million (or 45%), revenue
from customers in Asia declined $3.3 million (or 4%), and revenue from customers
in Europe and other areas increased $13.6 million (or 36%). Changes in the
geographic mix of revenue resulted primarily from changes in the timing of
customers' orders, lower sales of natural uranium to domestic customers, and a
lower commitment level of a domestic customer.

Cost of Sales. Cost of sales amounted to $248.6 million in the first
quarter of fiscal 1999, a decline of $93.5 million (or 27%) from $342.1 million
in the first quarter of fiscal 1998. As a percentage of revenue, cost of sales
amounted to 81%, compared with 78% in the first quarter of fiscal 1998. Although
cost of sales in dollar terms declined as a result of the 28% reduction in sales
of SWU, the decline was partially offset by the effects of higher unit
production costs resulting from a significant reduction in production volume,
primarily at the Paducah GDP. The low production at the Paducah GDP in the first
quarter of fiscal 1999 was due to the Company's response to the high cost of
power, as discussed below. Continued sub-optimal gaseous diffusion cell
availability contributed to higher unit production costs at the Portsmouth GDP.

Persistent hot weather, high electricity demand in the Midwest and power
generation shortages resulted in record-high power costs from the early summer
into the fall with a resulting negative impact on the Paducah GDP's production
costs in the first quarter of fiscal 1999. The Company initially responded to
these events by curtailing production at the Paducah GDP to reduce the impact of
these higher power prices on production costs. Because the power costs continued
to remain unusually high in August, September and into October, the Company
extended its response by restoring production at the Paducah plant over a longer
period than contemplated earlier in the summer, and will be increasing total
production over the remainder of the fiscal year to help meet production and
cost targets.

Under the Company's monthly moving average inventory cost method, most of
the impact of the higher power costs and lower production volumes on unit
production costs is expected to affect cost of sales over the remainder of the
fiscal year.

19

21

Electric power costs amounted to $90.9 million (representing 54% of
production costs) compared with $113.0 million (representing 55% of production
costs) in the first quarter of fiscal 1998, a decline of $22.1 million (or 20%).
The decline in power costs was attributable to lower production volumes at the
GDPs, principally at the Paducah GDP. Although electric power costs were lower,
costs per megawatt hour increased 30% over the first quarter of 1998.

Costs for the future disposition of depleted uranium amounted to $5.2
million, a decline of $9.3 million (or 64%) from $14.5 million in the first
quarter of fiscal 1998. Lower costs in the first quarter of fiscal 1999 reflect
a lower future disposal rate per kilogram of depleted uranium based on
fixed-cost disposal contracts for a certain quantity of depleted uranium and the
lower production levels at the GDPs. At September 30, 1998, the accrued
liability for the future disposal of depleted uranium amounted to $4.3 million.
In July 1998, pursuant to the USEC Privatization Act, depleted uranium generated
by the Company from July 1993 to July 1998 was transferred to DOE, and the
accrued liability of $373.8 million at the time of the IPO, on July 28, 1998,
was transferred to stockholders' equity.

Subsequent to the IPO, production costs in the first quarter of fiscal 1999
include charges for taxes other than income taxes and property insurance
premiums.

SWU purchased under the Russian HEU Contract represented 46% of the
combined produced and purchased supply mix, compared with 40% purchased from the
Russian Federation and DOE in the first quarter of fiscal 1998. The Company's
cost of sales has been, and will continue to be, adversely affected by amounts
paid to purchase SWU under the Russian HEU Contract at prices that are
substantially higher than its marginal production cost at the GDPs. As the
volume of Russian SWU purchases has increased, the Company has operated the GDPs
at lower production levels resulting in higher unit production costs. Pursuant
to the Russian HEU Contract, Russian HEU purchases will peak in calendar year
1999 at 5.5 million SWU per year and are expected to remain at that level
thereafter.

Gross Profit.  Gross profit amounted to $59.3 million, a reduction of $39.0
million (or 40%) from $98.3 million in the first quarter of fiscal 1998. As a
percentage of revenue, gross profit amounted to 19%, compared with 22% in the
first quarter of fiscal 1998. The lower gross profit reflects lower sales of SWU
primarily from changes in the timing of customers' orders and the effects on
cost of sales of lower production volume and higher unit costs at the GDPs.

Project Development Costs.  Project development costs, primarily for the
AVLIS project, amounted to $31.6 million, a decline of $.6 million (or 2%) from
$32.2 million in the first quarter of fiscal 1998. Development costs for the
future commercialization of the AVLIS uranium enrichment process primarily
reflect integrated operation of the laser and separator systems to verify
enrichment production economics.

Selling, General and Administrative.  Selling, general and administrative
expenses amounted to $7.9 million, a decline of $.2 million (or 3%) from $8.1
million in the first quarter of fiscal 1998. As a percentage of revenue,
selling, general and administrative expenses amounted to 2.6%, compared with
1.8% in the first quarter of fiscal 1998.

Operating Income.  Operating income amounted to $19.8 million in the first
quarter of fiscal 1999 compared with $58.0 million in the first quarter of
fiscal 1998. The decline reflects lower gross profit.

Interest Expense.  Interest expense of $6.5 million in the first quarter of
fiscal 1999 represents interest on borrowings of $550.0 million incurred at the
time of the IPO. Prior to the IPO, the Company had no short or long-term debt.
Outstanding borrowings under a credit agreement averaged $557.6 million during
the period from July 28 to September 30, 1998, at a weighted average interest
rate of 6.8%, including the amortization of fees.

Provision for Income Taxes.  The provision for income taxes includes a
special income tax benefit of $54.5 million for deferred income tax benefits
that arise from the Company's transition to taxable status. Deferred tax
benefits represent differences between the carrying amounts for financial
reporting purposes and the Company's estimate of the tax bases on its assets and
liabilities.

20

22

Excluding the special tax benefit, the provision for income taxes was $6.3
million in the first quarter of fiscal 1999, of which $3.0 million was incurred
in July 1998, subsequent to the IPO.

Net Income.  Including the special tax benefit, net income was $63.1
million compared with $60.0 million in the first quarter of fiscal 1998.
Excluding the special tax benefit, net income in the first quarter of fiscal
1999 was $8.6 million. Net income in the first quarter of fiscal 1999 was
affected by lower gross profit primarily from the timing of customer orders,
lower gross profit margins, interest expense on borrowings incurred at the time
of the IPO, and the provision for income taxes following the Company's
transition to taxable status.

Fiscal 1999 Outlook.  First quarter results are on target, and revenue for
fiscal 1999 is anticipated to be in line with analysts' expectations. However,
fiscal 1999 costs will be greater than previously estimated because the effects
of record-high electric power costs continued from early summer into the fall,
an unanticipated downward revision in the inflation index by the Department of
Commerce is expected to affect revenue, and increased interest and income tax
expenses are anticipated. The Company believes its fiscal 1999 earnings could be
about 25 percent below analysts' consensus estimate of $1.60 per share.

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

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 changes in 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, the Company
provided enrichment services for 100 reactors as compared with 110 in fiscal
1997. The average SWU price billed to customers was $116, an increase of
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 changes in 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 under a new contract signed
by the Company.

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 changes in the timing of customers' orders, partially offset by the effects
of lower production volume and higher unit costs at the GDPs and an increase in
purchased SWU under the Russian HEU 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 the Company incurred
additional costs because uneconomic overfeeding of uranium was necessary at the
Portsmouth GDP to compensate for the production lost due to the unavailability
of cells 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 UF(6) 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

21

23

overall and, at the Paducah GDP, more efficient operations and economic
underfeeding of uranium which in turn resulted in a significant reduction in the
generation of depleted UF(6). At June 30, 1998, the Company had accrued a total
liability of $372.6 million for the future disposal of depleted UF(6).

SWU purchased under the Russian HEU 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 HEU Contract
are substantially higher than the Company's marginal cost of production. The
Company purchased SWU derived from HEU, 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 for the 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 changes in the timing of
customers' orders, lower production volume and higher unit costs at the GDPs,
and an increase in purchased SWU under the Russian HEU Contract.

Special Charges.  Special charges amounted to $46.6 million for fiscal 1998
for costs related to the Privatization and certain severance and transition
benefits to be paid to GDP workers in connection with workforce reductions over
the next two years.

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 future commercialization of 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 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 changes in the timing of customers'
orders and lower gross profit margins. Including special charges, net income in
fiscal 1998 amounted to $146.3 million.

On a pro forma basis, as if the IPO had occurred at the beginning of fiscal
1998, net income before special charges for fiscal 1998, adjusted to reflect
interest expense on borrowings of $550.0 million at the time of the IPO and a
provision for income taxes, was $97.3 million or $.97 per share. Including
special charges, net income on a pro forma basis was $68.4 million or $.68 per
share.

RESULTS OF OPERATIONS -- FISCAL YEARS ENDED JUNE 30, 1996 AND 1997

Revenue.  Revenue amounted to $1,577.8 million in fiscal 1997, an increase
of $165.0 million (or 12%) from revenue of $1,412.8 million in fiscal 1996. The
increase in revenue for fiscal 1997 resulted principally from: (i) the timing of
customer nuclear reactor refuelings; (ii) sales to new customers; and (iii)
increased sales to existing customers. Sales of SWU increased 14% in fiscal 1997
following a decline of 14% in fiscal 1996. During fiscal 1997, the Company
provided enrichment services for 110 reactors as compared with 101 in fiscal
1996. Revenue for fiscal 1997 included first time sales of SWU for five reactors
under Utility Services contracts entered into in earlier years and first time
sales for four reactors under new contracts. The average SWU price billed to
customers in fiscal 1997 was $115, a decline of approximately 1% compared to
fiscal 1996, reflecting the trend toward lower prices for new contracts in the
highly competitive uranium enrichment market.

22

24

Revenue in fiscal 1997 increased from fiscal 1996 in all geographic areas in
which the Company markets enrichment services. Domestic revenue increased $49.2
million or 5%, Asian revenue increased $46.2 million or 10%, and European and
other revenue increased $69.6 million, almost double the fiscal 1996 level. In
addition to changes in the timing of customer orders, revenue benefitted from
initial sales by the Company for six reactors in the United States, one in Asia,
and two in Europe. Revenue in fiscal 1997 was somewhat affected by the slowdown
of refueling orders for certain reactors in the United States that, for a
substantial portion of the fiscal year, had suspended operations pursuant to NRC
safety directives or extended outages.

Cost of Sales.  Cost of sales amounted to $1,162.3 million in fiscal 1997,
an increase of $189.3 million (or 19%) from $973.0 million in fiscal 1996. As a
percentage of revenue, cost of sales amounted to 74% and 69% for fiscal years
1997 and 1996, respectively. The increase in cost of sales in fiscal 1997 was
attributable mainly to the 14% increase in sales of SWU, higher unit production
costs at the GDPs and increased purchases under the Russian HEU Contract. SWU
production costs were higher due to unplanned equipment downtime and increased
preventive maintenance activities.

SWU production and related unit production costs in fiscal 1996 were
adversely affected by lower gaseous diffusion production capability and
increased maintenance activities reflecting efforts to restore GDP production to
desired levels. Additional costs were incurred in fiscal 1997 from overfeeding
of uranium in the enrichment process at the Portsmouth GDP to partially mitigate
lower production capability. In fiscal 1996, production capability at the
Paducah GDP was adversely affected by a reduction in electric power from the
power supplier in response to an extended period of extremely hot weather.

Electric power costs amounted to $530.4 million (representing 59% of
production costs) in fiscal 1997, compared with $486.9 million (representing 55%
of production costs) in fiscal 1996, an increase of $43.5 million (or 9%). The
increase reflects increased power consumption and, at the Portsmouth GDP, a
significant decline in power utilization efficiency along with higher demand
charges for firm power. Power utilization efficiency was adversely affected by
production equipment difficulties.

Costs for labor and benefits amounted to $230.1 million in fiscal 1997, an
increase of $20.3 million (or 10%) from $209.8 million in fiscal 1996. The
increase reflects general inflation and higher employment levels.

Costs for the future disposition of depleted UF(6) amounted to $72.0 million
in fiscal 1997, a decline of $18.6 million (or 21%) from $90.6 million in fiscal
1996. Costs were lower in fiscal 1997 as the estimated future disposal rate per
kilogram of depleted UF(6) was reduced as a result of revised estimates based on
new proposals from potential disposal companies.

Increased SWU purchases under the Russian HEU Contract and other purchase
contracts also contributed to the higher costs of sales in fiscal 1997.
Purchased SWU represented 23% of the combined produced and purchased supply mix
in fiscal 1997, compared with 16% in fiscal 1996. Unit costs of SWU purchased
under the Russian HEU Contract are substantially higher than the Company's
marginal cost of production. The Company purchased SWU derived from HEU, as
follows: 1.8 million SWU at a cost of $157.3 million and 1.7 million SWU at a
cost of $144.1 million for the fiscal years 1997 and 1996, respectively. In
September 1996, in accordance with the Privatization Act, the Company and Tenex
amended the Russian HEU Contract to eliminate the Company's obligation to
purchase the natural uranium component after calendar year 1996.

Gross Profit.  Gross profit amounted to $415.5 million in fiscal 1997, a
decline of $24.3 million (or 6%) from $439.8 million in fiscal 1996. Although
revenue increased in fiscal 1997, gross profit was adversely affected by higher
unit production costs at the GDPs caused mainly by unplanned equipment downtime
and increased preventive maintenance activities and increased purchases of SWU
under the Russian HEU Contract. Gross profit in fiscal years 1997 and 1996 was
also adversely affected by declines in average prices billed to customers.

Project Development Costs.  Project development costs, primarily for the
AVLIS project, amounted to $141.5 million in fiscal 1997, an increase of $37.9
million (or 37%) from $103.6 million in fiscal 1996. The increase reflects
planned engineering and development spending for the future commercialization of
the

23

25

AVLIS uranium enrichment process and, in fiscal 1997, initial costs incurred in
the evaluation of SILEX. Increased AVLIS spending was attributable to the
demonstration of laser and separator systems and preliminary plant design.

Selling, General and Administrative Expenses.  Selling, general and
administrative expenses amounted to $31.8 million in fiscal 1997, a decline of
$4.2 million (or 12%) from $36.0 million in fiscal 1996. As a percentage of
revenue, selling, general and administrative expenses amounted to 2.0% and 2.5%
in fiscal years 1997 and 1996, respectively. The decline in fiscal 1997 resulted
from a reduction in expenses associated with Privatization activities and lower
consulting and other fees.

Other Income.  Other income, net of expenses, amounted to $7.9 million in
fiscal 1997, an increase of $4.0 million (or 103%) from $3.9 million in fiscal
1996. The increase in fiscal 1997 was attributable to interest earned on
payments under the Russian HEU Contract to be applied against future SWU
deliveries and fees earned on delivery optimization and other customer-oriented
distribution programs.

Net Income.  Net income amounted to $250.1 million in fiscal 1997, a decline
of $54.0 million (or 18%) from $304.1 million in fiscal 1996. As a percentage of
revenue, net income amounted to 16% and 22% for fiscal years 1997 and 1996,
respectively. The decline in fiscal 1997 resulted primarily from an increase of
$37.9 million in AVLIS development spending and a lower gross profit margin on
sales of SWU.

LIQUIDITY AND CAPITAL RESOURCES

Liquidity and Cash Flow.  Net cash flows provided by operating activities
amounted to $28.6 million in the first quarter of fiscal 1999, compared with
$83.1 million in the first quarter of fiscal 1998. Excluding the special
deferred income tax benefit, cash flow in the first quarter of fiscal 1999
reflects lower net income as well as an increase of $26.9 million in inventories
and cash payments of $8.9 million for costs and expenses relating to the
Privatization incurred prior to the IPO. Net cash flows provided by operating
activities in the first quarter of fiscal 1998 had been reduced by an advance
payment of $60.0 million to DOE for electric power and had been increased by a
reduction of $27.9 million in inventories and advances of $14.1 million from
customers.

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 UF(6),
partly offset by an increase of $64.4 million in payables to the Russian
Federation for purchases of SWU. In fiscal 1997, the net increase of $50.1
million in payments under the Russian HEU Contract reflected a payment of $100.0
million in December 1996 under the Russian HEU Contract for future deliveries of
SWU in calendar years 1998 and 1999.

Net cash flows provided by operating activities amounted to $356.1 million
in fiscal 1997, a significant increase over $119.7 million in fiscal 1996. The
increase resulted primarily due to a reduction of $97.6 million in customer
trade receivables in fiscal 1997 from changes in the timing of customer
collections and the collection of $29.4 million from DOE for reimbursable
regulatory compliance activities, partially offset by the decline of $54.0
million in net income compared with fiscal 1996. As a supplementary activity in
support of the Russian HEU Contract, the Company paid $100.0 million in each of
fiscal years 1997 and 1996 as credits for future deliveries of SWU under the
Russian HEU Contract.

Capital expenditures relating primarily to GDP improvements amounted to $5.7
million in the first quarter of fiscal 1999, compared with $5.9 million in the
first quarter of fiscal 1998.

Capital expenditures relating primarily to GDP improvements amounted to
$36.5 million, $25.8 million and $15.6 million in fiscal years 1998, 1997 and
1996, respectively. Capital expenditures in fiscal 1998 consist principally of
replacement equipment and upgrades to the steam plant and cooling towers.
Capital expenditures in fiscal years 1997 and 1996 consisted principally of
upgrades to the steam plant and cooling towers, improvements to the enriched
product withdrawal facilities, process inventory control systems, cylinder
storage facilities and purchases of capital equipment.

24

26

The Exit Dividend paid to the U.S. Treasury in July 1998 amounted to
$1,709.4 million.

Dividends paid to the U.S. Treasury amounted to $120.0 million in each of
the fiscal years 1998, 1997 and 1996. Pursuant to the Privatization Act, in
December 1996, the Company transferred to DOE the natural uranium component of
LEU from HEU purchased under the Russian HEU Contract at a cost of $86.1 million
in fiscal 1996 and $74.3 million in fiscal 1997. As a result of the transfer,
the total purchase cost of $160.4 million, including related shipping charges,
was recorded as a return of capital.

On November 10, 1998 the Board of Directors of USEC Inc. declared the
Company's first regular quarterly dividend payment of $.275 per share, payable
December 15, 1998 to shareholders of record as of November 25, 1998. An
annualized dividend of $1.10 per common share was indicated in the IPO
Prospectus dated July 22, 1998. During 1999, the Company anticipates dividend
payment dates of March 15, June 15, September 15 and December 15.

Net working capital amounted to $766.6 million at September 30, 1998. The
Company has provided extended payment terms to an Asian customer with respect to
an overdue trade receivable of $36.5 million at September 30, 1998. Interest is
earned on the unpaid balance, and the trade receivable has been secured by an
irrevocable letter of credit with payment scheduled for February 27, 1999.

AVLIS Project Expenditures.  AVLIS deployment is estimated to cost
approximately $2.2 billion from fiscal 1998 through fiscal 2005, of which $550.0
million is expected to be spent during the performance demonstration, design and
licensing phase and $1.7 billion during the procurement, construction and
startup phase. The Company periodically re-evaluates its AVLIS estimated costs
and currently believes this estimate could vary by up to 20%.

Actual AVLIS expenditures may vary from this estimate based on the results
of development and demonstration activities or on account of changes in business
conditions, regulatory requirements and the timing of NRC licensing, costs of
construction labor and materials, the market for uranium enrichment services,
and the Company's cost of capital.

Capital Structure and Financial Resources.  The Company expects that its
cash, internally generated funds from operating activities, and available
financing sources including borrowings under the Credit Facility (described
below), will be sufficient to meet its obligations as they become due and to
fund operating requirements of the GDPs, purchases of SWU under the Russian HEU
Contract, capital expenditures and discretionary investments, AVLIS expenditures
in the near term and the quarterly dividend.

The Company borrowed $550.0 million at the time of the IPO, pursuant to a
credit facility comprised of three tranches (the "Credit Facility"). Tranche A
is a 364-day revolving credit facility for $400.0 million. Tranche B is a
364-day revolving credit facility for $150.0 million which is convertible, at
the Company's option, into a one-year term loan. The Company borrowed $550.0
million under Tranche A and Tranche B, transferred $500.0 million of such
proceeds to the U.S. Treasury as part of the Exit Dividend of $1,709.4 million
and retained $50.0 million in cash. The third tranche, Tranche C, is a five-
year revolving credit facility for $150.0 million for working capital and
general corporate purposes. Borrowings, net of repayments, amounted to $565.0
million from July 28 to September 30, 1998. Borrowings under the Credit Facility
bear interest at a rate equal to, at the Company's option (i) the London
Interbank Offered Rate ("LIBOR") plus an "Applicable Eurodollar Margin," or (ii)
the Base Rate (as defined). The Applicable Eurodollar Margin is based on the
Company's credit rating.

The Credit Facility requires the Company 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 Credit Facility
restricts borrowings by USEC subsidiaries to a maximum of $100.0 million. The
failure to satisfy any of the covenants would constitute an event of default.
The Credit Facility also includes other customary events of default, including
without limitation, nonpayment, misrepresentation in a material respect,
cross-default to other indebtedness, bankruptcy and change of control.

The Company's total debt-to-capitalization ratio as adjusted to include
short-term debt was 33% at September 30, 1998.

ENVIRONMENTAL MATTERS

In addition to costs for the future disposition of depleted UF(6), the
Company 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 relating to such
environmental compliance were $25.4 million, $24.9 million and $30.4 million and
capital expenditures relating to environmental matters were $4.4 million, $1.8
million and $3.5 million for fiscal years 1998, 1997 and 1996, respectively. In
fiscal years 1999 and 2000, the Company expects its operating costs and capital
expenditures for such compliance to remain at about the same levels as in fiscal
1998. Costs accrued for the future treatment and disposal of depleted UF(6)
produced from its operations were $55.7 million in fiscal 1998. The Company
expects that costs relating to the future treatment and disposal of depleted
UF(6) will be lower in fiscal 1999.

The Company paid $50.0 million to DOE in June 1998 in consideration for DOE
assuming responsibility for a certain amount of depleted UF(6) generated by the
Company from the Privatization Date to 2005.

Environmental liabilities associated with the GDP operations prior to the
date of the IPO are the responsibility of DOE or the U.S. Government, except for
liabilities relating to certain identified wastes stored at the GDPs.
Environmental liabilities associated with the decontamination and
decommissioning of the GDPs are generally the responsibility of DOE, except for
additional costs, if any, as a result of the Company's operations.

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 the Company's operations and
business processes and could fail or function inaccurately if not repaired or
replaced with Year 2000 ready products. The Company'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 the Company 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 Company has designed and begun implementation of a Year 2000 project
which focuses on systems that are critical to its business. The failure of such
critical systems would directly and adversely affect the Company's ability to
generate or deliver products and services or otherwise affect the Company's
revenue, safety, or reliability for a period of time as to lead to unrecoverable
consequences. The Company has adopted a phased approach for critical systems to
address the Year 2000 issue. The phases include: (1) a Company-wide inventory,
in which critical systems were identified; (2) assessment, in which critical
systems were evaluated as to their readiness to operate in the Year 2000; (3)
remediation, in which critical systems that are not Year 2000 ready are upgraded
by modification or replacement; (4) testing, in which remediation is validated
by checking the ability of critical systems to operate within the Year 2000 time
frame; and (5) certification, in which systems are formally acknowledged to be
Year 2000 ready and acceptable for operation.

The Year 2000 project is proceeding on schedule. The inventory phase has
been completed, and critical systems have been identified. Other software that
requires Year 2000 remediation may be included during the assessment,
remediation, and testing phases. The identified, critical, in-house and vendor
software is in the process of being remediated, with completion expected by
April 1999. The Company expects to complete the testing and certification phases
by April 1999.

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

26

28

The Company 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 the
Company's services may be adversely affected. The Company has adopted a phased
approach to address external parties and the Year 2000 issue. The phases
include: (1) inventory, in which critical business relationships are identified;
(2) action planning, in which a series of actions and a time frame for
monitoring expected compliance status is developed; (3) assessment, in which the
likelihood of external party Year 2000 readiness is evaluated; and (4)
contingency planning, in which plans are made to deal with the potential failure
of an external party to be Year 2000 ready. Additional critical relationships
may be entered into or included. Assessment of Year 2000 readiness of external
parties will continue through calendar year 1999.

In January 1999, the Company plans to assess the progress of Year 2000
remediation efforts internally and externally to determine the scope of
contingency planning necessary to reduce the risk to the Company. If the
remediation schedule lags and cannot meet certain milestones, a contingency
planning process would begin, and contingency plans would be implemented if a
remediated system does not become available by the date it is needed. The
Company also plans to develop contingency plans for the potential failure of
critical external parties to address their Year 2000 issues.

The Company 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. Irrespective of the
progress of the Company's Year 2000 project, the Company is preparing
contingency plans, which will take into account the possibility of multiple
system failures, both internal and external, due to Year 2000 effects.

There can be no assurance that such programs will identify and cure all
software problems, or that entities on whom the Company 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.

The Company expects its costs for software modifications and systems
upgrades to resolve Year 2000 issues will amount to $14.0 million, of which $5.8
million had been incurred at September 30, 1998. Pursuant to the Company'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.

POWER PURCHASES, CHANGING PRICES AND INFLATION

The GDPs require substantial amounts of electricity to enrich uranium. The
Company purchases firm and non-firm power to meet its production needs.
Production costs would increase to the extent that the market prices of non-firm
power, which represented 29% of the fiscal 1998 power needs, and firm power,
which represented 71% of the fiscal 1998 power needs, were to rise. In addition,
the prices that the Company pays for firm power could increase if there were
additional regulatory costs or unanticipated equipment failures at the power
plants supplying the firm power to the GDPs. The Company is exploring a number
of alternatives to reduce its exposure to market-priced power at the Paducah GDP
during next summer and future periods, including negotiations to procure power
at acceptable prices and reducing production levels at the Paducah GDP during
affected periods. There can be no assurance that the Company will be successful
in reducing such exposure, including through the procurement of power at
acceptable prices to economically operate the Paducah GDP during the affected
periods.

A majority of the Company's contracts generally provide for prices that are
subject to adjustment for inflation. In recent years, inflation has not had a
significant impact on the Company's operations, and unless inflation increases
substantially, it is not expected to have a material effect.

RECENTLY ISSUED ACCOUNTING STANDARDS

In June 1998, the Financial Accounting Standards Board issued and the
Company adopted Statement of Financial Accounting Standards No. 133, "Accounting
for Derivative Instruments and Hedging Activities." Adoption of the standards
did not have a material effect on the Company's financial statements for fiscal
1998.

INDUSTRY OVERVIEW

THE ENRICHMENT PROCESS

Overview.  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 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, or LEU, 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.

Two existing commercial technologies are currently used to enrich uranium
for nuclear power plants -- the gaseous diffusion process and the gas centrifuge
process. The gaseous diffusion process involves the passage of uranium
hexafluoride ("UF(6)") in a gaseous form through a series of filters (or porous
barrier) such that the UF(6) 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 a gaseous uranium that is enriched
in U(235), the fissionable isotope. The gaseous diffusion process is
power-intensive, requiring significant amounts of electricity to push the UF(6)
through the filters. The other enrichment process, gas centrifuge, is
significantly less power intensive than the gaseous diffusion process and
employs rapidly spinning cylinders containing UF(6) to separate the fissionable
U(235) isotope from the non-fissionable U(238).

SWU.  The standard of measure of effort or service in the uranium enrichment
industry is separative work units or SWU. A SWU is the amount of work or effort
that is required to transform a given amount of natural uranium feed stock
(UF(6) into two streams of uranium, one enriched in the U(235) isotope and the
other depleted of the U(235) isotope. Prices for enrichment services are based
upon SWU, and the enrichment capacity of suppliers and the enrichment
requirements of nuclear utilities are also denominated in SWU.

Overfeeding/Underfeeding.  SWU (and the related electricity required for
enrichment) and natural uranium are, to a certain extent, interchangeable in the
process to create enriched uranium. The Company can feed (i) more natural
uranium into the enrichment process, a mode of operation called "overfeeding,"
or (ii) less uranium into the enrichment process, a mode of operation called
"underfeeding." Overfeeding is economical if the sum of the value of the
additional natural uranium and the cost of disposing of the additional depleted
UF(6) generated is lower than the cost of the electricity used to produce the
additional enriched uranium. Underfeeding is economical if the cost of the
additional electricity required is lower than the savings from the use of less
natural uranium and its related disposal costs. Underfeeding serves to stockpile
the inventory of natural uranium which, if not needed for production, can be
sold.

THE NUCLEAR FUEL CYCLE

Electric utilities with light water nuclear reactors require fissionable
uranium because it is the act of fission which releases the necessary heat
required to produce steam for the turbines which generate electricity. The
provision of uranium enrichment services (i.e., the process by which the
concentration of the fissionable isotope U(235) in natural uranium is increased
to levels suitable for commercial use) is one vital step in the nuclear fuel
cycle as depicted in the diagram below. Utilities typically obtain natural
uranium as uranium ore concentrate from a mining and milling company or other
natural uranium supplier. Utilities arrange to have the uranium ore concentrate
converted to UF(6) at one of several converters located around the world. The
UF(6) is delivered to an enrichment services provider, such as the Company, for
enrichment in U(235). The enriched uranium is transported to a nuclear fuel
fabricator to have the enriched UF(6) converted into uranium dioxide pellets for
fabrication into fuel elements suitable for use in nuclear reactors.

PROVIDERS OF ENRICHMENT SERVICES

There are currently four major uranium enrichment suppliers worldwide: USEC,
Tenex, Eurodif and Urenco. Tenex is an entity of the Russian government. Eurodif
is a multinational consortium controlled by the French government. Other
participants in the consortium include the Spanish, Belgian, Italian and Iranian
governments. Urenco is a consortium owned one-third by the British government,
one-third by the Dutch government and one-third by two German utilities. Japan
Nuclear Fuels Limited ("JNFL") and a Chinese state-owned enrichment supplier are
smaller providers that primarily serve their respective domestic markets. In
addition, a relatively small spot market exists for uranium enrichment services.
The spot market developed in the mid-1980s as a result of utilities reselling
enrichment services that they were required to purchase under take-or-pay
contracts for reactors that were subsequently canceled or delayed and by SWU
sales from the former Soviet Union. By the early 1990s, however, the spot market
had declined in importance due to the elimination of utilities' excess
inventories and the impact of trade restrictions and market practices in certain
countries which have restricted sales from states of the former Soviet Union
into these markets. In 1997, the spot market supplied less than 2% of the total
world market for enrichment services.

In addition to the primary uranium enrichment suppliers, other sources of
enriched uranium exist. The principal source is LEU derived from HEU obtained
from dismantled United States and Russian nuclear weapons and military
stockpiles. As the Executive Agent to the U.S. Government under the Russian HEU
Contract, USEC purchases the uranium enrichment component of HEU recovered from
dismantled Russian nuclear weapons. USEC has also received transfers of HEU from
the U.S. Government. Russia has significant supplies of HEU from dismantled
weapons and military stockpiles; future disposition plans for this HEU are
unknown.

BUSINESS

OVERVIEW

USEC, a global energy company, is the world leader in the production and
sale of uranium fuel enrichment services for commercial nuclear power plants.
USEC currently has approximately a 75% share of the North American uranium
enrichment market and approximately a 40% share of the world market. Uranium
enrichment is a critical step in transforming natural uranium into fuel for
nuclear reactors to produce electricity. USEC enriches uranium utilizing the
gaseous diffusion process at two plants located in Paducah, Kentucky and near
Portsmouth, Ohio. USEC's fiscal 1998 revenue was $1.4 billion and its pre-tax
income, before special charges, was $192.9 million. The Company's net income on
a pro forma basis (primarily to reflect provision for federal, state and local
income taxes and interest expense) before special charges for fiscal 1998 was
$97.3 million.

The Company supplies enriched uranium to approximately 60 customers for use
in about 170 nuclear reactors located in 14 countries throughout the world.
Generally, the Company's contracts with its customers are "requirements"
contracts pursuant to which the customer is obligated to purchase a specified
percentage of its enriched uranium requirements from the Company. Consequently,
the Company's annual sales are dependent upon the customers' requirements for
the Company's services, which are driven by nuclear reactor refueling schedules,
reactor maintenance schedules, customers' considerations of costs, and
regulatory actions. Based on customers' estimates of their requirements, at
September 30, 1998 the Company had long-term requirements contracts with
utilities to provide uranium enrichment services aggregating approximately $3.6
billion through fiscal 2001 and $7.0 billion through fiscal 2009, compared with
$7.8 billion at September 30, 1997.

STRATEGY

The Company's goal is to continue to be the world's leading supplier of
uranium fuel enrichment services and to diversify over time into related
strategic businesses that will contribute to the Company's growth and
profitability. To achieve its goal, the Company intends to focus on the
following:

Aggressively Pursue Sales Opportunities.  The Company has implemented a
strategy designed to increase sales to existing customers, many of whom
currently buy less than 100% of their requirements from the Company (typically
70%) and to add new customers. Flexible contract terms have replaced
standardized DOE contracts, and the Company has increased its attention to
customer service, product quality and reliability. Management has implemented a
variety of private-sector marketing principles which emphasize responsiveness to
the needs of individual customers. In addition, USEC is committed to
capitalizing on its reputation as a reliable and timely supplier and to
delivering superior customer service. The Company has actively worked to reduce
delivery times and has implemented an electronic order service system to
facilitate management of customer orders and tracking of inventory.

Improve Operating Efficiencies.  The Company plans to continue to improve
operating efficiencies by implementing a rigorous cost management program. A
cornerstone of this program is USEC's commitment to continually investigate
opportunities to purchase low-cost power and to seek the most efficient use of
power to minimize the cost of power per SWU produced. The Company has also
adopted cost containment goals intended to be achieved through improved power
utilization, increased SWU production per labor hour, and other material and
service cost reductions. USEC is committed to containing operating costs while
ensuring continued compliance with health, safety and environmental standards.

Commercialize AVLIS Technology.  USEC plans to complete the development and
commence commercialization of the next generation of uranium enrichment
technology, AVLIS, which uses lasers to enrich uranium, and which should permit
USEC to remain one of the lowest cost suppliers of uranium enrichment services
and enhance its competitive position. The Company believes that it will be able
to deploy a full-scale AVLIS facility in the 2005-2006 time frame. In addition,
it is possible that the AVLIS technology may have applications in the medical,
precision tool and semiconductor industries which the Company may elect to
explore either on its own or through licensing arrangements. As AVLIS is being

31

33

brought on line for production, the GDP facilities and AVLIS are expected to
operate simultaneously. AVLIS is expected to be able to displace some or all of
the production of the GDPs; however, the Company will evaluate issues such as
market demand and other supply sources at that time prior to making any
decisions with respect to the GDPs.

Diversify Over the Longer Term.  The Company intends to diversify its
business over time into related strategic businesses that will contribute to the
Company's growth and profitability. This strategy could, among other things,
result in the Company becoming involved in other phases of the nuclear fuel
cycle that draw on its knowledge of the nuclear industry thereby allowing the
Company to become a leader in the global nuclear energy market. Although the
Company has not identified any acquisitions or strategic alliances, it intends
to pursue appropriate opportunities which, among other criteria, are expected
to:

- offer a favorable balance with respect to market potential and manageable
market entry risk;

- broaden USEC's operating base beyond its core business in ways that allow
for the leveraging of its core competencies;

- diversify risk by being counter-cyclical to existing business;

- earn returns in excess of certain financial benchmarks including USEC's
cost of capital; and

- be accretive to earnings within a reasonable period of time.

SALES AND MARKETING

One of the Company's top priorities has been to obtain additional
commitments from existing customers and to add new customers. In pursuing this
priority, the Company has initiated a flexible approach to both pricing and
service, including shortening customer order lead times and introducing systems
to manage natural uranium provided by customers, while implementing a variety of
initiatives designed to improve customer service.

The Company has contracts with 63 nuclear utility customers operating about
270 nuclear reactors located in 14 countries. USEC provides enrichment services
to 173 of these reactors. Domestic customer purchases accounted for 63% of the
Company's fiscal 1998 revenue and foreign customers represented 37%. The
proportion of annual revenue generated from domestic and foreign customers is
expected to remain relatively constant through the end of the decade.

As a part of its marketing strategy, the Company endeavors to differentiate
its services from those of its competitors. In this regard, the Company believes
that in making their purchasing decisions, utilities consider the price of
enrichment services to be the most significant factor; however, issues of
reliability, product quality and customer service are also important. The
Company believes that it offers competitive prices and that it delivers superior
customer service. In addition, the Company has a strong reputation as a reliable
long-term supplier of enrichment services. Consequently, the Company's marketing
strategy includes efforts to educate utilities to associate the combination of
these positive features -- competitive pricing, customer service,
reliability -- with the "USEC" name. USEC believes that this name "branding"
strategy will help differentiate its services from those of its competitors and
enhance its position as the industry leader.

No one customer accounted for more than 10% of the Company's fiscal 1998
revenue. The Company's 10 largest customers, which collectively represented 44%
of its fiscal 1998 revenue, included Arizona Public Service Company, Carolina
Power and Light Company, Commonwealth Edison Company, Duke Power Company, The
Kansai Electric Power Company, Incorporated (Japan), PECO Energy Company,
Southern Nuclear Operating Co., Taiwan Power Company, Tennessee Valley Authority
and Tokyo Electric Power Company, Inc.

The Company has provided extended payment terms to an Asian customer with
respect to an overdue trade receivable of $36.5 million at September 30, 1998.
Interest is earned on the unpaid balance, and the

32

34

trade receivable has been secured by an irrevocable letter of credit with
payment scheduled for February 27, 1999.

CUSTOMER CONTRACTS AND PRICING

Overview.  In excess of 95% of enrichment services are provided by primary
suppliers selling directly to utilities under multi-year contracts. While some
of these contracts are for fixed quantities, the vast majority are
"requirements" contracts. Under a requirements contract, enrichment services are
provided as and when needed. The amount of enrichment services actually
purchased, therefore, depends on a number of factors including the capacity and
performance of the reactor. Under this type of contract, the supplier receives
the benefit of increases and assumes the risk of reductions in demand.
Transactions are small in number but large in size, with a typical contract
exceeding $50 million in value. Purchasing strategies tend to differ by utility
size, region of the world and the relative value placed upon reliability, price
and flexibility. There is an emerging trend among utilities to divide their
purchases among several shorter-term contracts and stagger their renegotiations,
thereby giving themselves maximum flexibility to respond to the market.

The Company currently provides enrichment services to customers under two
types of requirements contracts. "Utility Services Contracts" are the uniform
contracts that were transferred to the Company by DOE on July 1, 1993 (the
"Transition Date"). "New Contracts" are (1) contracts negotiated or renegotiated
by the Company with existing and new customers since the Transition Date that
have been tailored to meet the particular needs of individual customers and (2)
certain Utility Services Contracts that have been substantially amended since
the Transition Date. A majority of USEC's customers has transitioned from older
Utility Services Contracts or equivalent contracts to New Contracts.

Utility Services Contracts.  As originally executed by DOE and certain
customers in 1984, the Utility Services Contracts have a term of 30 years. There
were 24 Utility Services Contracts at September 30, 1998, however, pursuant to
options granted by DOE in the Utility Services Contracts or otherwise, many of
these customers have terminated their purchase obligations for fiscal 1999 and
beyond. The Company believes that a majority of the customers that terminate
their purchase obligations under Utility Services Contracts will enter into New
Contracts with the Company.

New Contracts.  The Company's New Contracts are also primarily requirements
contracts. The New Contracts have been individually negotiated with each
utility. This has allowed the Company to tailor the economic, legal and
operational terms in response to specific customer needs. The terms of the New
Contracts have been in the range of 3 to 11 years and such contracts typically
do not contain advance termination provisions. Terms contained in the New
Contracts include establishment of accounts for customer-owned natural and
enriched uranium, allocation of financial responsibility for taxes and future
regulatory charges, limitation of liability for damages, and protection against
liability to third parties arising from nuclear incidents. Additionally,
consistent with the Company's goal of providing maximum flexibility to
customers, many New Contracts contain options, tailored to each customer's
particular needs, that permit customers to increase and decrease the percentage
of requirements purchased from USEC in specific years.

The Company believes that its willingness to provide flexible contract terms
has been instrumental in its ability to successfully compete for and capture
open demand. The Company also believes that the advent of shorter contract terms
is an industry-wide phenomenon: utilities have been experiencing rapid changes
in their industry and have been less willing to enter into extended obligations.
This trend toward shorter contract terms requires that the Company, as well as
its competitors, pursue new sales with greater frequency. The general effect of
this is to increase the level of competition among uranium enrichment suppliers
for new SWU commitments.

Calculation of Backlog.  Under both types of contracts, customers are
required to provide non-binding estimates of their SWU requirements to
facilitate the Company's ability to forecast production requirements and
revenue. Backlog is the aggregate dollar amount of enrichment services that the

33

35

Company expects to sell pursuant to its multi-year requirements contracts with
utilities. The Company expects most customers with Utility Services Contracts to
exercise their right to terminate commitments in years 2003 through 2008.

Pricing.  Uranium enrichment services are priced based upon SWU.
Historically, the U.S. Government established a uniform price under long-term
SWU contracts that was required by law to be based upon a recovery of the U.S.
Government's costs in producing SWU and was subject to annual adjustment.

The base price of the Utility Services Contracts transferred to the Company
on the Transition Date was $125 per SWU (the "Base Price"). The Company has not
increased the price under contracts transferred from DOE, and as of September
30, 1998 the price remained $125 per SWU. The Company's Base Price is generally
applicable to 70% of requirements purchased by customers under Utility Services
Contracts. This Base Price may be adjusted upward or downward by the Company
with 180 days' notice so long as it does not exceed a ceiling charge established
under a formula in the Utilities Services Contracts. In each of fiscal years
1997 and 1998, the average price billed to the Company's customers under the
Utility Services Contracts and New Contracts was approximately $115 per SWU.

Currently, although SWU is essentially a commodity product, there are no
standard indices in the long-term SWU market and contracts are entered into on a
confidential basis. New SWU prices under long-term contracts are influenced by
supply and demand dynamics in the market. Prices for uranium enrichment services
under the New Contracts are negotiated. They are influenced by the volume and
timing of the customer's open SWU commitments, perceptions of future market
prices and the variety of options and operational flexibility required. New
Contracts provide for prices that are significantly lower than the current Base
Price under the Utility Services Contracts, reflecting current market
conditions. New Contracts generally provide that prices are subject to
adjustment upward or downward for inflation based on the U.S. Department of
Commerce inflation index and, subject to certain limitations, for cost increases
incurred by the Company resulting from changes in regulatory requirements.

RUSSIAN HEU CONTRACT

Overview.  The Company 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 relating to the acquisition
of LEU derived from HEU recovered from dismantled nuclear weapons from the
former Soviet Union. In January 1994, the Company signed a commercial agreement
(the "Russian HEU Contract") with Tenex, Executive Agent for Minatom, which, in
turn, is the Executive Agent for the Russian Federation. Under the contract,
USEC expects to purchase up to approximately 92 million SWU contained in LEU
over a 20-year period according to a specified schedule. The LEU will be derived
from up to 500 metric tons of HEU being blended down in Russia to a level
suitable for commercial power reactor fuel.

In April 1997, the Company entered into a memorandum of agreement (the
"Executive Agent MOA") with the United States Department of State and DOE
whereby the Company has 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, the Company can be terminated, or resign,
as U.S. Executive Agent upon the provision of 30 days' notice. In the event of
termination or resignation, the Company 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.

SWU Component of Russian LEU from HEU.  USEC ordered 4.4 million SWU in
calendar 1998, of which 2.5 million SWU had been delivered as of October 31,
1998. Delivery of the remaining SWU ordered for delivery in calendar 1998 has
been delayed, and the Company currently does not anticipate receiving this
material prior to the end of this calendar year. In addition, USEC has ordered
5.5 million SWU for delivery in calendar 1999. USEC has committed to order up to
5.5 million SWU in each of the

34

36

calendar years 2000 and 2001. The quantities and prices for SWU purchases under
the Russian HEU Contract through 2001 have been set. Prices for SWU delivered in
1999, 2000 and 2001 are subject to adjustment based on U.S. inflation. The
contract provides that the parties will meet in 2000 and may at that time agree
on quantities and prices for the five years beginning in 2002. The Company
expects to purchase 5.5 million SWU in each of the years following 2001 during
the remaining term of the Russian HEU Contract.

The cost of Russian SWU is substantially higher than the Company's marginal
cost of producing SWU at the GDPs. Although the Company presently can resell the
Russian SWU for more than the Company is paying, such sales are less profitable
than sales of SWU produced at the GDPs. Nevertheless, as the only U.S. provider
of enrichment services today and as a result of its strong technical capability,
backlog and financial position, the Company believes that it is uniquely
positioned to act as U.S. Executive Agent under the Russian HEU Contract. The
Company believes it can best integrate this additional supply of enrichment
services into the market in a manner that minimizes market disruption and
ensures the reliability and continuity of economic supply to electric utilities.

USEC pays for the SWU delivered under the Russian HEU Contract within 60
days after delivery. In order to facilitate and support the Russian Federation's
implementation of the contract, however, the Company made advance payments to
Tenex of $60 million in calendar 1994 and $100 million in each of calendar years
1995 and 1996. USEC credits advance payments, up to $50 million per year,
against half of the SWU value in each delivery received and makes cash payments
for the remaining portion. As of September 30, 1998, $210.0 million of the
$260.0 million in advance payments had been credited against SWU purchased. From
inception of the Russian HEU Contract to September 30, 1998, the Company
purchased 8.5 million SWU derived from 46.4 metric tons of HEU at an aggregate
cost of $715.6 million, including related shipping charges.

Natural Uranium Component of Russian HEU.  Although the Russian HEU Contract
as originally executed in 1994 obligated USEC to purchase the natural uranium
component of LEU deliveries, USEC and Tenex amended the contract in 1996 in
accordance with the Privatization Act to provide that, with respect to all LEU
deliveries under the contract after January 1, 1997, USEC would transfer the
natural uranium component of such deliveries to Tenex. Consequently, since
January 1997, USEC has purchased (and has committed to purchase in the future)
only the SWU component of LEU delivered by Tenex under the contract. With
respect to deliveries in calendar years 1995 and 1996, as directed by the
Privatization Act, USEC purchased both the SWU and natural uranium components
and transferred the natural uranium component to DOE in December 1996.

NATURAL URANIUM AND HEU FROM DOE

Under the Privatization Act, DOE transferred to the Company title to 50
metric tons of HEU. The 50 metric tons of HEU represents 3.4 million SWU and
5,000 metric tons of natural uranium. The Company is responsible for costs
related to the blending of the HEU into LEU, as well as certain transportation,
safeguards and security costs. The Company received the 7,000 metric tons of
natural uranium in April 1998 and anticipates receiving the 50 metric tons of
HEU over the period September 1998 to September 2003. The Privatization Act
places certain limits on the ability of the Company to deliver this material for
commercial use in the United States. In particular, the Company may not deliver
for use in the United States (i) more than 10% of the uranium in any calendar
year, or (ii) more than 800,000 SWU contained in LEU in any calendar year.

In May 1998, the Company also received an additional 3,800 metric tons of
natural uranium and 45 metric tons of LEU to settle DOE's liabilities for
nuclear safety upgrade costs and to satisfy certain other remaining obligations
of DOE to the Company. The 45 metric tons of LEU represent 280,000 SWU and 453
metric tons of natural uranium. The Company may not deliver such uranium for
commercial use in the United States over less than a four-year period.

35

37

At September 30, 1998, the Company had inventories of 11.1 million SWU and
29,000 metric tons of natural uranium, including 3.4 million SWU and 5,000
metric tons of natural uranium contained in 50 metric tons of HEU scheduled to
be delivered to the Company by DOE over the period September 1998 to September
2003.

The average annual price in the spot market for a kilogram of uranium as
UF(6), based on month-end data, was $32.38 for the period January to September
1998, $37.10 in 1997, $46.71 in 1996, $35.59 in 1995, $29.66 in 1994, and $30.59
in 1993.

Depending on customer requirements and other factors, the Company expects to
retain the equivalent of approximately 5,000 metric tons of natural uranium to
meet ongoing operational requirements, and would anticipate, over time, selling
the remaining inventory. USEC plans to sell this natural uranium gradually, as
uranium or together with SWU in the form of enriched uranium product, through
2005. The Company intends to manage its sales of natural uranium so as to not
significantly affect the U.S. natural uranium market.

GDPS/OPERATIONS

The Company's GDPs at Paducah and Portsmouth are among the largest
industrial facilities in the world. The process buildings at the two GDPs have a
total floor area of approximately 330 acres and a ground coverage of about 167
acres. The GDPs are designed so that groups of equipment can be taken off line
with little or no interruption in the process.

Paducah.  The Paducah GDP is located in McCracken County in western
Kentucky. The total site covers 750 acres and consists of four process
buildings. The plant has been in continuous operation since September 1952.
Between 1971 and 1982, the plant underwent extensive improvements.

Paducah 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 GDP is shipped to the Portsmouth GDP for further
enrichment. The Company may seek approval to operate Paducah to produce enriched
uranium up to 5% U(235), which would provide the Company with additional
operating flexibility to meet customer requirements. In order to ship enriched
uranium to fuel fabricators from this facility, certain modifications to the
shipping and handling facilities at the Paducah GDP would be required.

Portsmouth.  The Portsmouth GDP is located in Pike County in south central
Ohio. The plant site covers 640 acres and consists of three process buildings.
It was completed in 1956 and has been in continuous operation since that time.
The Portsmouth GDP was substantially renovated between 1971 and 1983.

The Portsmouth GDP was originally designed and constructed to produce HEU
for the United States Nuclear Weapons and Naval Reactors program. Because of a
change in military requirements, the HEU production equipment was taken out of
service. The plant has been certified by the NRC to produce enriched uranium to
a maximum of 10% U(235). The design capacity of the production equipment is 7.4
million SWU per year.

Equipment and Parts.  The process equipment at the GDPs has historically had
low failure rates. Failed components (such as compressors, coolers, motors and
valves) are removed from the process and repaired or rebuilt on site at each of
the GDPs. Common industrial components, such as the breakers, condensers and
transformers in the electrical system, are procured as needed. Since the GDPs
were initially constructed in the 1950s, some components and systems may no
longer be produced, and spares for such 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 used to design and build replacements. Another
source of replacement equipment has been DOE's Oak Ridge, Tennessee enrichment
facility which has been shut down. Large quantities of components have been
relocated from Oak Ridge to the GDPs.

36

38

The GDPs currently use freon as the primary process coolant. The production
of freon in the United States was terminated December 31, 1995. In order to
ensure that the Company continues to have enough freon to meet its needs, the
Company is actively working to reduce leakage of freon at the GDPs. Freon leaks
from pipe joints, sight glasses, valves, coolers and condensers. Leakage from
the GDPs is at about a 6% rate, resulting in leakage of approximately 750,000
pounds of freon per year. The Company has a strategic reserve of 2.7 million
pounds of freon. The Company believes that its efforts to reduce freon losses
and its strategic inventory of freon should be adequate to allow the GDPs to
continue to use freon through at least the year 2001. A program is underway to
validate an alternative coolant to be used once the freon inventory is depleted.

Cell Availability.  In order to utilize power most efficiently, the Company
seeks to maintain 90% or more of its large production cells on line. From the
Transition Date through June 30, 1998, the Paducah GDP has generally operated
with 85% to 97% of the large production cells in operation. Reductions in cell
availability are typically short-term and result from equipment failures and
planned maintenance. In addition, the Company may elect to reduce cell
availability if electricity becomes in short supply and prohibitively expensive.
For the year ended June 30, 1998, performance was 92% of planned capacity. From
the Transition Date through June 30, 1998, the Portsmouth GDP has generally
operated in the range of 65% to 92% of the large production cells in operation.
For the year ended June 30, 1998, the plant performance was at 72% of planned
capacity due to equipment failures and increased maintenance requirements. The
ability to return cells to service quickly at the Portsmouth GDP has been less
successful than at the Paducah GDP, due to the greater availability of larger
cells at the Paducah GDP. Because both GDPs produce approximately the same
amount of enriched uranium, the Portsmouth GDP, with fewer large cells, is
required to operate more efficiently with fewer cells off-line to produce
equivalent amounts of SWU as the Paducah GDP. This mode of operation necessarily
results in more maintenance requirements for the cells at the Portsmouth GDP.
Management has initiated a program designed to improve both the availability and
reliability of the cells at the Portsmouth GDP.

LMUS Contract.  Under an operations and maintenance contract with Lockheed
Martin Utility Services, Inc. ("LMUS"), a subsidiary of Lockheed Martin
Corporation, USEC manages the GDPs and LMUS operates and maintains the GDPs (the
"LMUS Contract"). LMUS provides the labor, services, materials and supplies
required to operate and maintain the GDPs, other than the required natural
uranium and power. The Company pays LMUS for its costs, subject to strict budget
controls and various caps on liability. LMUS is paid a base fee and has the
ability to earn incentive fees by demonstrated improvements in production
capability, regulatory performance, cost reduction, safety and customer
responsiveness. There is also a provision for an independent additional one-time
bonus at the end of the initial three-year contract. The LMUS Contract expires
on October 1, 2000, and may be terminated by the Company without penalty upon
six months' notice.

Under the LMUS Contract, USEC is responsible for and accrues for its pro
rata share of pension and other post-retirement health and life insurance costs
relating to LMUS employee benefit plans. Post-retirement benefits are provided
to LMUS employees under Lockheed Martin Corporation employee benefit plans with
LMUS participating as an affiliated employer.

Lease Agreement.  The Company leases the GDPs from DOE pursuant to a lease
agreement dated as of July 1, 1993 (the "Lease Agreement"). The Lease Agreement
had an initial term of 6 years; however, the Company has the right to extend it
indefinitely, with respect to either or both GDPs, for successive renewal
periods. In June 1997, the Company renewed the Lease Agreement for both GDPs for
an additional five-year term expiring on June 30, 2004. The Company may
terminate the Lease Agreement, with respect to one or both GDPs, by providing
two years' prior notice to DOE. The Company leases most, but not all, of the
buildings and facilities at the GDP sites. The Company 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 the Company. At termination of the Lease Agreement, the

37

39

Company may leave the property in "as is" condition, but must remove all waste
generated by the Company which is subject to offsite removal and must place the
GDPs in a safe shutdown condition. Upon termination of the Lease Agreement, DOE
is responsible for the costs of all decontamination and decommissioning of the
GDPs. If removal of any USEC capital improvements increases DOE's
decontamination and decommissioning costs, the Company is required to pay such
increases. Title to capital improvements not removed by the Company will
automatically be transferred to DOE at the end of the Lease Agreement term. At
September 30, 1998, the Company had accrued a liability of $24.5 million for
lease turnover costs and anticipates accruing $5.6 million for lease turnover
costs in fiscal 1999. See "Risk Factors -- Risks Associated with Enrichment
Operations -- Termination of Lease Agreement."

Lease Agreement payments include a base rent representing DOE's costs in
administering the Lease Agreement, including costs relating to the electric
power contracts, and costs relating to DOE's regulatory oversight of the GDPs.
The Company expects that the cost of the Lease Agreement, and leases for office
space and equipment to be approximately $5.0 million in fiscal 1999.

DOE is required under the Lease Agreement to indemnify the Company for
certain costs and expenses, including:

- certain environmental liabilities attributable to operations prior to the
Transition Date;

- certain employee pension, welfare and other benefits or liabilities
incurred or accrued prior to the Transition Date; and

- costs or expenses relating to actions taken or not taken prior to the
Transition Date pursuant to contracts transferred to the Company on the
Transition Date.

In addition, under the Lease Agreement DOE is required to indemnify the
Company for costs and expenses related to claims asserted against or incurred by
the Company arising out of DOE's operation, occupation or use of the GDPs after
the Transition Date. DOE activities at the GDPs since the Transition Date have
been focused primarily on environmental restoration and waste management and
management of depleted UF(6). DOE is required to indemnify the Company against
claims for public liability (1) arising out of or in connection with activities
under the Lease Agreement, including transportation and (2) arising out of or
resulting from a nuclear incident or precautionary evacuation. DOE's obligations
are capped at the $8.96 billion statutory limit set forth in the Price-Anderson
Act for each nuclear incident or precautionary evacuation occurring inside the
United States.

POWER

Overview.  The GDPs require substantial amounts of electric power. Costs for
electricity are the Company's largest operating cost, representing 53% to 59% of
the Company's production costs. A substantial portion of the electricity for the
GDPs is supplied under contracts at average prices below 2c/kWh in fiscal 1998
and 2.7c/kWh in the three months ended September 30, 1998. Historically, USEC
has purchased approximately two-thirds of its requirements under firm contracts,
and the remaining one-third as non-firm energy.

At recent electricity rates, average production cost per SWU is lowest when
the GDPs are operated at a production level of approximately 13 million SWU per
year. At this production level, the plants require approximately 33 million
megawatt hours of electric energy per year or an average power level of 3,700
megawatts. On average, during fiscal years 1998, 1997, 1996 and 1995, the GDPs
were run at capacities that required 1,076, 1,400, 1,455 and 1,845 megawatts
respectively, at the Portsmouth GDP and approximately 1,307, 1,725, 1,480 and
1,875 megawatts respectively, at the Paducah GDP. Operation of both GDPs at full
capacity requires approximately 5,200 megawatts, which is equivalent to the
approximate annual electricity consumption of the States of Connecticut or
Arkansas. However, USEC anticipates that its energy consumption will decrease as
its supply mix changes.

In the 1950s, a number of utilities formed two corporations to supply power
to the GDPs -- Electric Energy, Inc.("EEI") to serve the Paducah GDP and Ohio
Valley Electric Corporation ("OVEC") to serve the Portsmouth GDP. Pursuant to
power purchase agreements between DOE and OVEC and EEI,

38

40

each of which extends through calendar 2005, most of the electricity produced at
the two power plants owned by OVEC and approximately one-half of the electricity
produced at the plant owned by EEI serves the GDPs. DOE transferred the benefits
of these power purchase arrangements to USEC by agreement. The Company also has
an agreement with the Tennessee Valley Authority for the purchase of non-firm
power for the Paducah GDP.

The Company has initiated a number of programs to reduce its power costs,
including programs designed to:

- increase the efficiency of power utilization (i.e., the number of SWU
produced per MWh of electric energy);

- manage the use of existing power resources to minimize cost per MWh; and

- pursue additional sources of economical power.

Since non-firm power prices and reliability of supply vary with the time of
year, time of day and weather conditions, the ability to adjust the Paducah
GDP's electrical load in response to availability and price changes is an
essential element in managing power costs. Therefore, the Paducah GDP operates
equipment which facilitates the rapid changes of load on its enrichment
equipment, permitting corresponding rapid changes in electric load. This allows
the Paducah GDP to swing as much as 400 MW of electrical load in one to two
hours, providing prompt response to changes in the price of non-firm power.
Decisions to purchase non-firm power are based upon production needs,
anticipated power costs and production cost targets (dollar per SWU criteria).

Power Purchase Agreements.  Pursuant to the EEI power purchase agreement,
EEI is obligated to provide two types of firm power: "permanent Joppa power" and
"firm additional power." Permanent Joppa power refers to the power that USEC
receives from EEI's Joppa, Illinois plant. EEI is obligated to provide, and USEC
through DOE, is obligated to purchase, a specified percentage of that plant's
annual capacity, which percentage is currently 60% but will be reduced to 50%
effective January 1, 1999. USEC is obligated (i) to pay the demand charge,
reflecting the pro rata share of operating costs, depreciation, interest
charges, taxes and return on owner's capital, for the specified percentage
regardless of whether USEC takes any energy and (ii) to pay an energy charge,
which covers the pro rata share of the cost of fuel, for the energy USEC does
take. If additional transmission facilities are required to deliver energy from
non-EEI sources, USEC must pay 75% of these costs. In addition, USEC is
obligated to pay any unamortized costs of additional or modified transmission
facilities if it terminates the agreement. Either party may, on an annual basis,
reduce its respective obligation by up to 10% of Joppa plant capacity with
notice on or before the prior September 1. In addition, each party may reduce
its obligation by a greater amount or terminate its obligation in its entirety
with five years' notice.

Firm additional power refers to power that is supplied by the utility owners
of EEI when permanent Joppa power is insufficient to meet the minimum power
requirements of the Paducah GDP. The rate for firm additional power is EEI's
cost plus a fee of up to $1.00 per MWh. EEI has discretion over when the
permanent Joppa power will be made available to USEC during the year. As a
result, EEI typically supplies USEC with the more costly firm additional power
during the peak demand periods of winter and summer, while supplying USEC with
the permanent Joppa power during the low demand periods of spring and fall.
Either party may cancel its commitment with respect to firm additional power by
providing three years' written notice.

Under the OVEC power purchase agreement, OVEC must make available to USEC
(through DOE) the net available capacity of its generating plants, less
transmission losses and reserve capacity. The cost of permanent power consists
of an energy charge, which covers the cost of fuel, and a demand charge, which
reflects capital and operating costs, debt service, taxes and a return on
owner's capital. In addition, USEC is required to pay the costs of additional
and replacement facilities. In the event USEC purchases less than OVEC's net
available capacity, then USEC must pay the demand charge but not the energy
charge. USEC may reduce its purchase obligation by up to 300 MW per six-month
period by giving 60-months' notice and may also terminate the agreement upon
three years' notice. If USEC needs power from sources
39

41

other than OVEC's two power plants, OVEC is obligated to use its best efforts to
obtain such power. This power may come from OVEC sponsoring companies or other
sources and will be charged at OVEC's cost plus a fee of $1.00 per MWh. OVEC
does not have the right to terminate the agreement or reduce its obligation.

At current production levels at the Portsmouth GDP, the Company does not
need all of the power that it is obligated to purchase from OVEC, and,
consequently, negotiates to reduce its purchases of the power from OVEC as
agreed upon by the parties from time to time. The negotiation historically has
involved the reduction of the demand component of the OVEC power charge to USEC.
Consequently, while USEC is not obligated to pay the energy component of power
that is not utilized, the Company does pay a reduced demand charge for power not
taken.

Arrangements with DOE.  While DOE remains the "named" purchaser under the
power purchase agreements with EEI and OVEC, under an agreement with DOE, DOE
must make available to USEC the power that it receives under the agreements. DOE
must take all actions requested by USEC that are consistent with the terms of
the power purchase agreements, including giving its consent to any modification,
assignment or termination of the power purchase agreements requested by USEC,
except for those which would either extend the term of an agreement or be
inconsistent with DOE orders concerning procedures for contracting for utility
services. DOE may not agree to any amendment, assignment or termination or
otherwise exercise any rights or consent to any action of EEI or OVEC without
the consent of USEC except in specified circumstances, such as an emergency.

Under the terms of the Lease Agreement, USEC must provide power purchased
from EEI or OVEC to DOE for DOE's continuing environmental restoration and waste
management operations at the Paducah and Portsmouth GDPs, and DOE must reimburse
USEC for that power.

USEC is responsible for all costs associated with the power purchase
agreements after the Transition Date, including its pro rata share of
post-retirement obligations, and USEC and DOE are required to share the costs
for the decommissioning, shut-down, demolition and closing of OVEC's power
plants and the costs for the demolition and shutdown of EEI's power plant. With
respect to OVEC, these costs are allocated on the basis of the relative amount
of energy consumed by OVEC, DOE and USEC subsequent to October 14, 1992, and,
with respect to EEI, these costs are allocated on the basis of the relative
amount of energy consumed by EEI, DOE and USEC over the life of the power
purchase agreement.

ADVANCED LASER-BASED TECHNOLOGY

AVLIS.  USEC plans to complete the development of and commence
commercialization of AVLIS, the next generation of uranium enrichment
technology, with the goal of remaining one of the lowest cost suppliers of
uranium enrichment service and enhancing its competitive position. Commercial
deployment of AVLIS is expected to begin in fiscal 2005. Based on engineering
studies and demonstrated systems performance capability, the Company believes
that an AVLIS facility would use 5% to 10% of the power currently used by the
GDPs to produce each SWU, require significantly less capital investment than new
centrifuge plants, and use about 20% to 30% less natural uranium to produce
comparable amounts of enriched uranium. In addition, the ability to use modular
architecture in designing a laser-based system allows for flexible deployment,
enabling capacity to be added as market demand so warrants.

AVLIS Deployment.  AVLIS deployment is expected to be accomplished in two
phases and was estimated in September 1997 to cost approximately $2.2 billion.
The Company periodically re-evaluates its AVLIS estimated costs and currently
believes this estimate could vary by up to 20%. The first phase, performance
demonstration, design and licensing, began in fiscal 1996 and extends through
fiscal 2002. The estimated cost of the first phase is approximately $550.0
million for fiscal 1998 through fiscal 2002. During this phase, the Company
expects to:

- demonstrate the plant-like performance of the feed production, enrichment
and product conversion processes by the end of 1999;

- complete the final design and detailed cost estimate for an AVLIS
facility; and

40

42

- select a site for the AVLIS facility and obtain NRC licensing and other
regulatory approvals for the construction and operation of the AVLIS
facility.

Once the first phase is successfully completed, the Company will initiate the
second phase.

The second phase, procurement, construction and startup, is expected to
begin in fiscal 2002 and end in fiscal 2006 with the deployment of AVLIS to
planned capacity. The estimated cost to complete this phase is approximately
$1.65 billion. During this phase, the Company expects to:

- procure the equipment for and begin construction of the AVLIS facility;

- develop plant operation procedures and train plant engineers and
supervisors;

- startup the AVLIS facility and train operations and maintenance staff; and

- conduct final testing and perform system activation and integration.

The Company currently anticipates operation of the AVLIS plant at an 9.0 million
SWU capacity.

USEC has made certain significant strides toward its goal of deploying
AVLIS, including the following: USEC has entered into an agreement with DOE
pursuant to which USEC received royalty-free rights to the AVLIS technology for
uranium enrichment and the ability to utilize DOE's AVLIS facilities at Lawrence
Livermore National Laboratory in Livermore, California ("LLNL"). Second, a
USEC-managed group was established to help implement the AVLIS project. Third, a
plant-like demonstration project was initiated which included an independent
assessment of the state of development of the AVLIS enrichment process which
resulted in clear identification of components and systems requiring priority
attention. USEC has activated and expanded the LLNL demonstration facility to
simulate a one-line enrichment plant and achieved positive performance
demonstration levels in laser and separator systems. Demonstration of plant-
like enrichment capability is scheduled to occur in calendar 1998. Fourth, the
Company has entered into joint development agreements with Cameco Corporation
("Cameco") for AVLIS feed conversion services and General Electric Company
("GE") for AVLIS product conversion services. USEC is also exploring joint
development of an alternative UF(6) product conversion facility with another
commercial vendor.

The Company is using LLNL to provide scientific and engineering expertise in
the performance verification and design areas. The Company has retained Bechtel
Group, Inc. to perform architect engineering, engineering systems, and control
systems services. Allied Signal Corporation is providing operations and
maintenance technicians for operation of the demonstration facility at LLNL. BWX
Technologies (formerly Babcock and Wilcox Naval Nuclear Fuels Division) is
providing separator engineering and licensing services. All of the foregoing
activities are being and will continue to be managed by the Company.

Ownership of Property Relating to AVLIS.  In April 1995, the Company entered
into an agreement with DOE (the "AVLIS Transfer Agreement") providing for, among
other things, the transfer to USEC by DOE of its intellectual and physical
property pertaining to the AVLIS technology. DOE has agreed to assign those
patents to USEC subject only to certain rights of the U.S. Government to use the
patents (as well as certain other AVLIS-related intellectual property) for
governmental purposes. Under the agreement, the Company is not obligated to pay
DOE any royalties for its own use of AVLIS, or to pay any portion of royalties
received from licensing AVLIS to third parties for enrichment of uranium or
other materials for use in facilities for generating electricity.

Under the AVLIS Transfer Agreement, DOE conducts AVLIS research, development
and demonstration at LLNL as requested by the Company. The Company reimburses
DOE for its costs in conducting AVLIS work, and the Company is liable for any
incremental increase in DOE's costs of decontamination and decommissioning the
AVLIS facilities at LLNL as a result of the work performed for the Company. The
AVLIS research and development work is performed primarily by the University of
California under DOE's management and operations contract for LLNL. Inventions
that result from this research and development effort will be owned by the
Company.

Nuclear Fuel Cycle Issues.  Because AVLIS requires a metallic form of
uranium for processing rather than UF(6), new industrial capabilities will be
required to prepare the feed for enrichment and to convert the enriched product
to a form suitable for fabrication as fuel. The Company has entered into joint
development agreements with Cameco for AVLIS feed conversion services and GE for
AVLIS product conversion services. Under such agreements, if USEC elects not to
proceed from the demonstration phase to the deployment phase, but Cameco or GE,
as the case may be, elects to proceed, or if the agreement is terminated under
certain circumstances, USEC must reimburse Cameco or GE, as the case may be, for
costs and expenses incurred by them in accordance with the project budget and
plans, and Cameco or GE, as the case may be, must transfer certain rights in
technology and intellectual property developed in the course of the project to
USEC. In the event USEC determines not to deploy AVLIS, these agreements
together provide for a maximum cost reimbursement to GE and Cameco of $9.0
million prior to such decision, subject to certain provisions for any cost
overruns. As of September 30, 1998, the Company's liability, in the event of
termination, to both GE and Cameco was $2.5 million. The Company's potential
liability under these agreements increases over time as GE and Cameco costs
increase.

If USEC proceeds with AVLIS deployment but elects to do so without entering
into an agreement with Cameco for feed conversion services or with GE for
product conversion services, USEC is obligated to pay Cameco or GE, as the case
may be, certain annual royalty payments. Any payments to Cameco would be based
on the amount of uranium used by USEC in the AVLIS feedstock. In such event,
these payments are estimated to total approximately $5 million per year for ten
years but would not exceed $50 million in the aggregate. Payments to GE would
include a fixed payment of $5 million plus an annual royalty of $1 million until
certain GE patents related to the product conversion expire. Royalty payments to
GE would only be made if USEC deployed a product conversion based on the
technology developed jointly with GE. The only obligation to GE would be costs
described in the preceding paragraph.

Pursuant to the AVLIS Transfer Agreement and the management and operating
contract between DOE and the University of California (which operates LLNL for
DOE), DOE is required to indemnify the University of California and the Company
under the Price-Anderson Act against public nuclear liability which arises out
of or in connection with research, development and demonstration activities at
LLNL. The Energy Policy Act provides, however, that new uranium enrichment
facilities will not be eligible for indemnification by DOE or the NRC under the
Price-Anderson Act. The Company believes that it should be able to obtain
commercially available nuclear liability insurance for all facilities needed to
enrich and process uranium by AVLIS.

Additional Potential Applications of AVLIS Technology.  In addition to
uranium enrichment, the Company is exploring strategic opportunities for other
commercial uses of the AVLIS technology, such as the separation of other
isotopes for nuclear power, medical and industrial applications and for
machinery, drilling and coating applications. In connection with pursuing all or
any of these technologies, the Company may determine to explore the feasibility
of pursuing new business opportunities and may license the technology to others.
Under the terms of the AVLIS Transfer Agreement, the Company must pay to DOE a
portion of the royalties received by the Company for licensing to third parties
applications of AVLIS (other than enrichment of uranium and other materials used
in the generation of electricity).

Intellectual Property.  The Company holds a large number of patents covering
the AVLIS technology and relies on the patent laws, confidentiality procedures
and contractual provisions to protect its proprietary information and
intellectual property rights related to AVLIS. In the 1970s, a company which was
at that time working on laser isotope separation filed a number of patent
applications certain of which were issued and are currently in effect, and three
of which will still be in effect in 2005. That company has advised USEC of its
belief that AVLIS will use the company's technology. In addition, the Company is
aware of patents issued to third parties which cover certain technology used in
laser-based products. The Company believes that the systems planned to be
employed by the Company in an AVLIS plant will not infringe on any issued
patents held by third parties, or that the Company will be able to obtain
necessary licenses or take other actions to otherwise avoid infringement. There
are also 12 classified patent applications held by

42

44

the above-mentioned company resulting from its work on laser isotope separation.
If national security considerations ever allow these applications to be
declassified and issued, these additional patents would be enforceable for 17
years from the date of issuance. The Company believes that declassification of
these patent applications is unlikely. In addition, if these applications were
declassified and patents issued and the holder thereof was able to make a
successful claim of infringement, the Company believes that it would be able to
obtain licenses to such patents or re-engineer the affected apparatus, system or
method.

SILEX.  USEC continues to keep abreast of alternative uranium enrichment
technologies. In fiscal 1997, USEC entered into an exclusive agreement to
explore another advanced laser-based enrichment technology, called SILEX. The
SILEX process has been under development in Australia since 1992 by Silex
Systems Limited, an Australian company, at the facilities of the Australian
Nuclear Science and Technology Organization. In fiscal 1997, 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 deployable as an
economic source of enrichment production in the early 21st century. Through
September 30, 1998, the Company has spent $10.6 million on SILEX development
activities.

COMPETITION

The highly competitive global uranium enrichment industry has four major
producers -- USEC; Tenex, a Russian government entity; Eurodif, a consortium
controlled by the French government; and Urenco, a consortium of the British and
Dutch governments and private German corporations. 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 handful of primary
suppliers, there is an excess of production capacity as well as an additional
supply of enriched uranium which is available for commercial use from the
dismantlement of nuclear weapons in the former Soviet Union and the United
States. Most of this excess capacity is held by Tenex, which is subject to
certain trade restrictions. USEC also holds significant excess capacity. All of
the Company's competitors are owned or controlled by foreign governments which
may make business decisions based on factors other than economic considerations.

Tenex, Urenco and Japan Nuclear Fuels Limited ("JNFL") use centrifuge
technology which requires a higher initial capital investment but has lower
ongoing operating costs than current gaseous diffusion technology. Urenco and
JNFL have both announced expansion plans, which together could increase capacity
by 2.0 million SWU after the year 2000. Eurodif and JNFL have previously
announced that they are exploring new enrichment technologies.

The Company believes that it is well positioned to compete successfully in
the industry. Global enrichment suppliers compete primarily in terms of price,
and to a lesser degree on reliability of supply and customer service. The
Company believes that its prices are competitive. Further, the Company is
committed to delivering superior customer service. The Company believes that
customers are attracted to its reputation as a reliable long-term supplier of
enriched uranium, and the Company intends to continue strengthening this
reputation.

REGULATORY OVERSIGHT

NRC.  Pursuant to the Atomic Energy Act ("AEA"), the GDPs are regulated by
the NRC. The NRC issued Certificates of Compliance to USEC for the operation of
the GDPs in November 1996. After an interim period to allow an orderly
transition from DOE oversight to NRC oversight, the Certificates of Compliance
became effective and the NRC began regulatory oversight of USEC operations at
the plants on March 3, 1997. The NRC found the Paducah and Portsmouth GDPs to be
generally in compliance with NRC regulations but exceptions were noted in
certain compliance plans, which set forth binding commitments for actions and
schedules to achieve full compliance (the "Compliance Plan"). The Lease
Agreement obligates DOE to reimburse USEC for the costs associated with bringing
the GDPs into compliance with the requirements of initial Certification. To
settle this reimbursement, DOE has transferred to the Company uranium and LEU in
the aggregate amount of $220 million, and thus the Company is now fully
responsible for these costs.

43

45

The Compliance Plan requires the Paducah GDP to complete seismic upgrading
of two main process buildings to reduce the risk of release of radioactive and
hazardous material (UF(6)) in the event of an earthquake. On March 20, 1998, the
NRC issued direction for USEC to complete this upgrade project by June 30, 1999,
which was originally estimated to cost $23.0 million, all of which was
reimbursed to the Company by transfers of uranium from DOE prior to the
Privatization. The Company currently believes it will need additional time to
complete this project at an additional cost in excess of $30.0 million, a
significant portion of which will be capitalized as permanent improvements to
the facilities. Until the modifications are completed, the Company continues to
maintain strict limits on operations in those buildings so as to minimize the
amount of material that could be released in the event of any earthquake. The
Company also was required to complete seismic upgrades on certain equipment at
the Paducah GDP by September 30, 1998, which the Company completed on time. The
Compliance Plan also required the Company to update part of the DOE-prepared
Safety Analysis Report ("SAR") to determine what the appropriate earthquake
level should be for the evaluation of plant equipment and structures at the
Paducah GDP. The Company has submitted this updated analysis and it is currently
being reviewed by the NRC. Depending on the results of this updated analysis of
the seismic hazard and the application of the NRC's backfit requirements,
additional seismic upgrades to the process buildings and other site structures
and components may need to be implemented.

In accordance with the Compliance Plans, USEC submitted for NRC review
DOE-prepared SAR updates. In addition, USEC is required to prepare and submit to
the NRC an update of the facility and process descriptions contained in the
current application. Depending on the results of the NRC review of the SAR
updates and the facility and process description updates, USEC will be required
to implement a number of changes to the plants and operations.

The NRC has the authority to issue Notices of Violation ("NOVs") for
violations of the AEA, NRC regulations, or conditions of a certificate,
Compliance Plan, or Order and to impose civil penalties for certain violations
of NRC regulations. The Company has received NOVs for violation of these
regulations and certificate conditions, none of which exceeded $100,000. From
time to time, the Company has received and may receive proposed notices of
violations from the NRC. The Company does not expect that any proposed notices
that it has received as of the date hereof will have a material adverse effect
on the Company's financial position. In each case, USEC took prompt corrective
action to bring the facilities back into compliance with NRC regulations and
identified long-term improvements as well.

Maintaining the certificates is conditioned upon adherence to Compliance
Plans. The term of the initial NRC certification expires December 31, 1998.
Subsequent certifications will be for periods of up to five years. In addition,
the NRC must approve any transfer of the certificates. The Privatization Act
prohibits the issuance of a license or certificate of compliance to the Company
or its successor if the NRC determines that:

- the Company is owned, controlled or dominated by an alien, a foreign
corporation or a foreign government;

- the issuance of such a license or certificate of compliance would be
inimical to the common defense and security of the United States; or

- the issuance of such a license or certificate of compliance would be
inimical to the maintenance of a reliable and economical domestic source
of enrichment services.

DOE retains certain regulatory responsibility for those portions of the GDPs
which are leased to USEC that contain HEU material. DOE will regulate the HEU
material activities that occur in the leased areas until all cylinders that
contain HEU material are cleaned, and the associated areas are brought under NRC
regulation. Cylinder cleaning is scheduled to be completed in calendar 2000.

OSHA.  The Company's operations are also subject to laws and regulations
governing worker health and safety. Through September 30, 1998, the Company had
spent $28.9 million to address potential

44

46

Occupational Safety and Health Act ("OSHA") non-compliances identified by DOE at
the Transition Date. Interim actions have been taken to reduce any immediate
health and safety risks associated with these potential non-compliances. The
Company estimates that cash outlays aggregating $4.6 million from September 30,
1998 through 2000 will be required to address the remaining potential
non-compliances. DOE has paid the Company the $35.0 million required by the
Lease Agreement for modifications of the GDPs necessitated by OSHA standards in
effect on the Transition Date.

ENVIRONMENTAL MATTERS

Overview.  The GDPs were operated by DOE and its predecessor agencies for
approximately 40 years prior to the Transition Date. As a result of such
operation of the GDPs, there are contamination and other potential environmental
liabilities. The Paducah GDP has been designated as a Superfund site, and both
GDPs are undergoing investigations under the Resource Conservation and Recovery
Act ("RCRA"). The Privatization Act provides that the U.S. Government or DOE
remains responsible for all liabilities arising from operation of the GDPs
before the Privatization except for liabilities relating to certain identified
wastes stored at the GDPs as of the Privatization that were generated after the
Transition Date, including liabilities relating to the disposal of such waste
after the Privatization. In addition, the Privatization Act and the Lease
Agreement provide that DOE remains responsible for decontamination and
decommissioning of the GDPs. Under the AVLIS Transfer Agreement, DOE is
generally responsible for the decontamination and decommissioning (except for
additional costs, if any, as a result of USEC's operations) and any liability
attributable to or arising out of DOE's ownership or operation of the LLNL,
including, without limitation, those relating to pollution or contamination or
any environmental claim (except for those resulting from the negligence or
misconduct of USEC). The Company, however, retains liability for, and agrees to
reimburse DOE for any liability attributable to actions taken by the Company or
its agents, employees or contractors with respect to operation, occupation or
use of, or activities at, LLNL or the AVLIS facility after the Privatization.

The Lease Agreement generally requires DOE to indemnify the Company for all
costs and expenses arising out of DOE's operation of the GDPs for matters
relating to:

- pollution or contamination from DOE's operations prior to the Transition
Date;

- environmental claims for which DOE has assumed liability;

- liability as a result of the Company's status as a permittee, holder,
signatory, operator, assignee or successor, to the extent such liability
arises from DOE's operation prior to the Transition Date; and

- liability arising from polychlorinated biphenyls ("PCBs"), asbestos and
certain other contaminants, except to the extent any such material has
been introduced by the Company.

In addition, the Lease Agreement requires DOE to indemnify and reimburse the
Company for all costs and expenses arising from DOE's activities (which have
been focused primarily on environmental restoration, waste management and
management of depleted UF(6)) at the GDPs after the Transition Date and requires
the Company to indemnify and reimburse DOE for all costs and expenses arising
from the Company's operations at the GDPs after the Transition Date. See
"Business -- Lease Agreement." The Privatization Act generally provides that
liabilities attributable to the operations of the Company prior to the
Privatization remain liabilities of the U.S. Government. To the extent an issue
arises as to whether liability resulted from pre- or post-Privatization
operations or releases of substances, USEC would seek to apply customary methods
of establishing and allocating liability. USEC would negotiate in good faith
with the U.S. Government and would evaluate a variety of factors in recommending
each party's pro rata share of responsibility, such as the nature of the
contaminant, the history of use, and the length of respective operations.

The Company's operations are subject to numerous federal, state and local
laws and regulations relating to the protection of health, safety and the
environment, including those regulating the emission and discharge into the
environment of materials (including radioactive materials). The Company is
required to

45

47

hold multiple permits under these laws and regulations. Environmental compliance
is a high priority with the Company. The Company has established an internal
environmental regulatory policy and oversight group that reports directly to
senior management and has created incentives in the operating contract with LMUS
predicated on compliance with environmental requirements.

In addition to costs for the future disposition of depleted UF(6), the
Company incurs operating costs and capital expenditures for matters relating to
compliance with environmental laws and regulations, including handling,
treatment and disposal of hazardous, low-level radioactive and mixed wastes
generated as a result of its operations. Operating costs relating to
environmental matters amounted to approximately $25.4 million, $24.9 million and
$30.4 million for fiscal years 1998, 1997 and 1996 respectively, and capital
expenditures relating to environmental matters amounted to approximately $4.4
million, $1.8 million and $3.5 million for fiscal years 1998, 1997 and 1996,
respectively. In fiscal years 1999 and 2000, the Company expects its operating
costs and capital expenditures for compliance with environmental laws and
regulations, including the handling, treatment and disposal of hazardous,
low-level radioactive and mixed wastes to remain at about the same levels as in
fiscal years 1997 and 1998 (exclusive of costs for future disposition of
depleted UF(6)).

The ultimate costs under environmental, health and safety laws and the time
period during which such costs are likely to be incurred are difficult to
predict and can be significantly affected by changes in existing law. However,
the Company currently believes that environmental capital expenditures and costs
will not have a material adverse effect on its financial condition, results of
operation or liquidity.

Low-Level Radioactive Waste.  The Company's operations generate low-level
radioactive waste which is currently either stored on-site or shipped off-site
for disposal at a commercial facility. Additionally, the Privatization Act
requires DOE to accept for disposal, upon the Company's request, all low-level
radioactive waste generated by the Company as a result of its operations at the
GDPs. The Company is required to reimburse DOE for this service in an amount
equal to DOE's cost, but in no event greater than the amount which would be
charged for such service by commercial, state, regional or interstate compact
entities.

Mixed Waste.  The Company generates mixed waste, which is waste having both
a hazardous and radioactive component. The Company has contracted for and is
shipping most of its mixed wastes off-site for treatment and disposal. Because
of limited treatment and disposal capacity, however, some mixed wastes generated
by the Company since the Transition Date are being temporarily stored at DOE's
permitted storage facilities at the GDPs. Although RCRA and its Kentucky and
Ohio counterparts generally require the Company to dispose of such wastes within
certain time periods, the Company has entered into consent orders with the
States of Kentucky and Ohio which permit the continued storage of mixed wastes
generated by the Company at DOE-permitted storage facilities at the GDPs and
provide for a schedule for sending such wastes to off-site treatment and
disposal facilities, generally by the year 2000. The Company believes that it
will treat or dispose of all of its historically generated mixed wastes within
the time periods set forth in the consent orders (generally by the year 2000).
However, there can be no assurance that the Company will be able to meet these
deadlines due to a number of factors, including the amount of time required for
the Company to determine the character of the wastes, the limited availability
of treatment capacity, and whether the Company's waste streams can meet the
treatability criteria established by treatment facilities. If the Company cannot
meet the schedules, it may be required to request extensions and continued
approval of the storage of mixed waste at the GDPs. There can be no assurance
that such extension or approval will be given, in which case the Company may be
subject to enforcement action, including fines and penalties.

Uranium Hexafluoride Tails.  The Company's operations generate depleted
UF(6), or "tails," as a result of its operations at the GDPs, which is currently
being stored at the GDPs. Since the Transition Date, the Company has generated
significant quantities of depleted UF(6). The Privatization Act and an agreement
related to the disposition of depleted UF(6) provide that all liabilities
arising out of the disposal of depleted

46

48

UF(6) generated before the Privatization are direct liabilities of DOE. Depleted
UF(6) generated after the Privatization is the responsibility of the Company.

The Privatization Act requires DOE, upon the Company's request, to accept
for disposal depleted UF(6) generated after the Privatization, if it is
determined to be a low-level radioactive waste, and also requires the Company to
reimburse DOE for this service in an amount equal to its cost. Costs accrued for
the future treatment and disposal of depleted UF(6) were $55.7 million in fiscal
1998. The Company expects that costs relating to the future treatment and
disposal of depleted UF(6) produced from its operations will be lower in fiscal
1999. If, as discussed below, depleted UF(6) were also regulated as a hazardous
waste, the Company estimates that it would incur additional costs to construct
and permit storage facilities, as well as additional operating costs. Since
there are no commercially available treatment facilities in the United States to
convert significant quantities of depleted UF(6) into a form suitable for
disposal, there can be no assurance that the Company's accruals for the disposal
of depleted UF(6) will be adequate or that the increased cost of treatment,
storage or disposal will not adversely affect the Company's financial condition
and results of operations in the event that UF(6) were regulated as a hazardous
waste.

The Company entered into an agreement with DOE pursuant to which the Company
paid DOE $50.0 million in June 1998 in consideration for a commitment by DOE to
assume responsibility for a certain amount of depleted UF(6) generated by the
Company over the period from the Privatization up to 2005.

The State of Ohio issued a Notice of Violation in September 1993 to DOE
which alleged DOE violated the State's hazardous waste regulations in its
failure to determine whether depleted UF(6) stored at Portsmouth constituted a
hazardous waste. DOE has recently signed a consent order with the State of Ohio
which permits it to continue to manage depleted UF(6) for ten years while
evaluating alternative management options. The Commonwealth of Kentucky and the
State of Ohio have made similar oral inquiries to the Company with respect to
whether depleted UF(6) constitutes a hazardous waste. The Company believes, and
DOE and NRC have also both taken the position, that depleted UF(6) is a source
material and therefore not a hazardous waste subject to RCRA. Although neither
Kentucky nor Ohio has taken any further action relating to this matter, there
can be no assurance that the EPA or Kentucky or Ohio will agree with the
position taken by DOE and NRC, and if not, the storage of UF(6) at the GDPs
could constitute a violation of RCRA.

Contamination of the GDPs.  Under the federal Comprehensive Environmental
Response, Compensation and Liability Act, as amended ("CERCLA"), and similar
state laws, the owner or operator of real property may be jointly and severally
liable for the costs of removal or remediation of certain hazardous or toxic
substances on or under such property, regardless of whether the owner or
operator knew of, or was responsible for, the presence of such materials. The
Paducah GDP, including the leased premises, has been designated on the National
Priorities List, more commonly known as a Superfund site under CERCLA. However,
the Privatization Act makes DOE or the U.S. Government responsible for any
liability in connection with contamination occurring prior to the Privatization.
In addition, the Lease Agreement requires DOE to indemnify the Company for all
such cleanup costs attributable to operations prior to the Transition Date.

The GDPs are currently undergoing investigations under RCRA. In connection
with such investigations, DOE has identified a number of areas of potential
contamination that may require remediation. Some of these areas are located
within the leased premises and some will continue to be used by the Company. The
Company has not determined whether or to what extent such continued use may
contribute to the contamination of these units. Pursuant to the Privatization
Act, the Company is liable for contamination, if any, attributable to the
Company's operations after the Privatization, and such costs are not subject to
reimbursement by DOE.

PCBs.  The federal Toxic Substances Control Act ("TSCA") regulates, among
other things, the manufacture, use, storage and disposal of PCBs. Both GDPs
contain significant amounts of equipment which have leaked PCB-contaminated oils
or which have become contaminated by such oils or store PCB

47

49

wastes in violation of TSCA. Pursuant to the Lease Agreement, however, DOE has
agreed to reimburse and indemnify the Company for any damages incurred by the
Company resulting from PCBs or PCB releases from existing equipment, except to
the extent any PCBs have been introduced to the GDPs by the Company.

DOE has operated the GDPs pursuant to a Federal Facility Compliance
Agreement ("FFCA") with EPA in which EPA has agreed not to sue DOE and any of
its contractors for alleged violations of TSCA resulting from the
PCB-contaminated equipment so long as DOE adheres to certain procedures.
Pursuant to the FFCA, DOE has undertaken substantial capital improvements to
protect the environment from PCB contamination and to reduce the exposure of
workers to PCBs. However, no assurance can be given that private parties which
are not bound by the FFCA may not seek to enjoin the use of PCBs at the GDPs in
violation of TSCA. The Company believes that such a lawsuit is unlikely and that
it would have defenses in the event of such a lawsuit, including a lawsuit
seeking suspension of plant operations.

Wastewater.  The Company and DOE share wastewater discharge facilities at
both GDPs that intermingle their respective wastewaters in such a way that it
may not always be possible to determine the origin of discharges that do not
comply with the plants' discharge permits. As a result, the Company may be fined
for violation of its permit as a result of DOE's operations. Although it may not
always be possible to establish that noncomplying discharges originated from DOE
operations, pursuant to the Lease Agreement DOE has agreed to indemnify and
reimburse the Company for any liability incurred by the Company as a result of
DOE's contribution to an alleged violation of permit limits.

Air Emissions.  The Company has filed applications for permits under Title V
of the Clean Air Act relating to its air emissions. The application for the
Portsmouth GDP includes, among other things, sources covered by appeals of
conditions in 56 air permits recently proposed by the State of Ohio. The
Company's applications are currently pending and it is not known when the
permits will be issued. The permits, when issued, may contain new or additional
conditions or emissions standards that may adversely affect the Company's
operations.

Transportation.  Transportation of natural uranium and enriched uranium
product to and from the GDPs is the responsibility of the Company's customers in
all but a few cases. The Company transports uranium between the two GDPs by rail
and by truck and is responsible for transportation of the Russian LEU from St.
Petersburg, Russia. The uranium material is packaged in cylinders which are
placed in protective overpacks and shipped on container ships and carried by
trucks using special trailers.

FOREIGN TRADE MATTERS

Antidumping Investigations.  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. In the antidumping
investigation that followed, Commerce rendered a preliminary determination that
uranium imported from Russia and several other former Soviet republics was being
dumped in the United States at average dumping margins of 115%. Thus, those
imports were exposed to the risk of high U.S. antidumping duties if the
investigation proceeded to a conclusion and if the U.S. International Trade
Commission (the "ITC") also determined that those imports were causing or
threatening material injury to the U.S. industry. The investigations of Russia,
Kazakhstan, Kyrgyzstan, Tajikistan, Ukraine, and Uzbekistan were suspended as a
result of "suspension agreements" between Commerce and the respective
governments. The agreements with Tajikistan and Ukraine have since been
terminated. Imports of uranium from Ukraine are currently subject to antidumping
duties.

Imports from Russia.  The Russian suspension agreement provides that while
all of the HEU, or LEU derived from the HEU, purchased from Russia pursuant to
the Russian HEU Contract could enter the United States, the associated natural
uranium could not be resold in the United States. The Privatization Act
supersedes this provision by allowing sales and deliveries of the associated
natural uranium in the United States subject to annual quantitative limitations.

48

50

In 1994, the Russian suspension agreement was modified (the "Modified
Suspension Agreement") to allow, subject to quotas, imports of Russian uranium
and SWU if they were "matched" in equal parts with newly-produced United States
uranium and/or SWU in a sale to an end-user in the United States. While quotas
for matched natural uranium exist until 2004, the SWU matching quota expired on
October 3, 1998. Unless the Modified Suspension Agreement is otherwise amended,
no imports of SWU from the Russian Federation (other than those associated with
the Russian HEU Contract) will be allowed until at least 2004.

Commerce and the ITC are scheduled to initiate a review of the Modified
Suspension Agreement in August 1999 under legislation that requires periodic
review of antidumping and countervailing duty orders and suspension agreements.
Under this review, known as a "sunset review," these agencies will determine
whether termination of the Modified Suspension Agreement would lead to the
continuation or recurrence of material injury or dumping. If either agency makes
a negative determination (i.e., that termination would not lead to injury or
dumping), the Modified Suspension Agreement would be terminated, without
replacement. By statute, the earliest date that the Modified Suspension
Agreement can be terminated is January 1, 2000.

Commerce may also terminate the Modified Suspension Agreement on its own
initiative if Commerce determines that the Modified Suspension Agreement no
longer satisfies the statute. In such case, Commerce and the ITC would restart
their antidumping investigations. If Commerce and the ITC issued affirmative
final determinations, imports of uranium from Russia would be subject to
antidumping duties, which could be very high, and could increase the price USEC
pays for SWU under the Russian HEU Contract. If, however, a negative final
determination were issued by either agency, then antidumping duties would not be
imposed and such uranium could then be sold in competition with USEC-supplied
natural uranium, SWU or LEU. Depending on the quantity of natural uranium, SWU
or LEU involved, such imports could have a material adverse effect on the
Company.

In addition, expiration of the Modified Suspension Agreement in 2004 or an
earlier modification or termination could affect the level of imports to the
United States of SWU from the Russian Federation. The likelihood of such
changes, and the effect of such changes on the operations of the Company, if
any, is uncertain.

Imports from Other CIS Countries.  Imports of uranium from Kazakhstan,
Kyrgyzstan and Uzbekistan are currently subject to antidumping suspension
agreements as well. Under the terms of these agreements, imports of uranium from
these countries are subject to certain quantitative restrictions. Under the
Kazakhstan and Uzbekistan suspension agreements, natural uranium that is
enriched in a third country prior to importation to the U.S. is considered to
originate from those countries, and is, therefore, subject to the quotas
established in the suspension agreements. The suspension agreements provide that
the quantitative restrictions contained therein are to remain in force until
2004. The modification or termination of the suspension agreements prior to that
date, if any, could affect the level of imports to the U.S. of uranium from
those countries, and the level of imports to the U.S. of LEU enriched from such
uranium in third countries. The effect of such changes on the operations of the
Company, if any, is uncertain.

As with the Modified Suspension Agreement, the suspension agreements
covering imports of uranium from Kazakhstan, Kyrgyzstan and Uzbekistan also
could be terminated by Commerce under certain circumstances. If an agreement
were terminated with respect to any one or more of these countries, then the
previously-suspended antidumping investigation would very probably resume with
respect to that country or countries. If Commerce and the ITC issued affirmative
final determinations, then antidumping duties would be imposed on imports of
uranium from that country or those countries. Imposition of an antidumping order
on imports of uranium from Kazakhstan, Kyrgyzstan and Uzbekistan could severely
limit or preclude entirely sales in the United States of uranium from those
countries. If, however, a negative final determination is issued by either
agency, then antidumping duties would not be imposed and such uranium could then
be sold in competition with USEC-supplied natural uranium, SWU or LEU.

49

51

Depending on the quantity of natural uranium, SWU or LEU involved, such imports
could have a material adverse effect on the Company.

As with the Modified Suspension Agreement, Commerce and the ITC are
scheduled to initiate a sunset review of these suspension agreements in August
1999, and either agency could order the termination of any or all of these
agreements. The earliest date that these suspension agreements can be terminated
is January 1, 2000. The effect on the Company of termination of any or all of
these suspension agreements as a result of the sunset review is uncertain since
it is not known whether the antidumping investigations would be restarted and
whether antidumping duties would be imposed.

Imports of uranium from Ukraine, other than HEU, are currently subject to an
antidumping duty order, under which the U.S. Customs Service imposes a 129.29
percent ad valorem cash deposit requirement. The rate of this cash deposit
requirement could change, based on further proceedings under the order. Changes
in the cash deposit rate, if any, could affect the levels of imports of uranium
from Ukraine, but the effect of such changes on the operation of the Company, if
any, is uncertain. This order is likely to remain in effect at least until 2000.

As with the Modified Suspension Agreement, in August 1999, Commerce and the
ITC will initiate a sunset review of these orders. As a result of this sunset
review, this order could be revoked, but the earliest date on which revocation
could occur is January 1, 2000. The effect of revocation of this order on the
Company is uncertain.

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

The Company exports to utilities in other countries under similar agreements
for cooperation. If such agreements for cooperation lapse, terminate or are
amended such that the Company could not make sales or deliver products to such
jurisdictions, it could have a material adverse effect on the Company.

LITIGATION

The Company 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 the Company's results of operations or financial position.

PROPERTIES

In addition to the two GDPs, see "Business -- GDPs/Operations" and "Business
- -- Lease Agreement," the Company leases its corporate headquarters office space
in Bethesda, Maryland under a lease expiring November 2008.

EMPLOYEES

As of September 30, 1998, the Company employed 159 people including 137 at
Company headquarters in Bethesda, Maryland, 13 at LLNL and 9 at the GDPs. The
Company believes that its relationship with its employees is good.

As of September 30, 1998, LMUS employed approximately 4,200 people at the
GDPs: 2,150 at the Portsmouth GDP, 1,800 at the Paducah GDP and 250 at LMUS
administrative headquarters. Of the 4,200 employees at the GDPs, 3,550 were
involved in enrichment operations and construction activities, and the remainder
involved primarily in DOE-funded activities. In addition, the Company directs
the activities of several contractors which employ 700 people at LLNL. See
"Business -- GDPs/Operations." The average years of service for the employees at
the GDPs is 13 years. Two labor unions, the Oil, Chemical and Atomic Workers
International Union ("OCAW") and the International Union of United Plant Guard
Workers of America ("UPGWA"), represent 1,110 LMUS employees at the Portsmouth
GDP (1,020

50

52

OCAW and 90 UPGWA) and 860 LMUS employees at the Paducah GDP (820 OCAW and 40
UPGWA). Subject to provisions of the Treasury Agreement, the Company plans
reductions in the GDP workforce of 500 persons, as well as an additional 100
persons through normal employee attrition, through fiscal year 2000. Any such
workforce reductions would be subject to applicable provisions of the Treasury
Agreement.

The Privatization Act provides that if the Company terminates or changes the
operating contractor at the GDPs, all pension plan assets and liabilities
relating to accrued benefits of the operating contractor's pension plan must be
transferred to a pension plan sponsored by the new contractor or the Company or
to a joint labor-management plan. The Privatization Act provides further that
any employer at a GDP (including the Company or any replacement contractors it
retains) must abide by the terms of any unexpired collective bargaining
agreement covering employees at the GDPs and in effect on the date of the
Privatization, until the expiration or termination of such agreement. If the
Company replaces its operating contractor, the new employer will be required to
offer employment to non-management employees of the predecessor contractor to
the extent that their jobs still exist or they are qualified for new jobs. In
addition, the Privatization Act requires that certain eligible employees of the
operating contractor at the GDPs continue to receive post-retirement health
benefits at substantially the same level of coverage as the level of benefits to
which eligible retirees were generally entitled as of the Privatization, and
requires the Company to fund such costs for the portion of time an employee
continues to work after the Transition Date.

The Privatization Act requires that Company employees who were covered under
certain U.S. Government retirement plans or health benefit plans as of the
Privatization (currently approximately 20 employees) elect (i) with respect to
pension benefits, to retain their coverage under the applicable government plan
or participate in a USEC plan (in which case the employee may receive or
transfer to the Company plan the retirement benefit payable to a terminated
employee under the government plan) and (ii) with respect to health benefits, to
retain their coverage under the applicable government plan or participate in a
USEC plan. The Company is required to fund the retirement and health benefits
(including government/administrative costs) for the employees who elect to
remain in government plans for the period they are Company employees.

Paducah Facility.  All hourly rated LMUS employees, excluding guards and
salaried employees, are represented by the OCAW, Local 3-550. The current
collective bargaining agreement expires on July 31, 2001. All hourly paid LMUS
security employees, excluding clerical employees, lieutenants, professional
employees, and supervisors, are represented by the UPGWA, Local 111. The current
collective bargaining agreement expires on March 1, 2002.

Portsmouth Facility.  All hourly rated LMUS security employees (excluding
shift commanders, the plant protection force section manager, captains, salaried
employees, office clerical employees, professional employees, supervisors and
all other persons employed by LMUS at the facility) are represented by the
UPGWA, Amalgamated Local 66. The current collective bargaining agreement expires
August 4, 2002. The collective bargaining agreement with OCAW, Local 3-689,
which represents all hourly employees, excluding security and salaried
personnel, expires on May 2, 2000. As of September 30, 1998, the Portsmouth GDP
has over 3,400 written grievances pending pursuant to the collective bargaining
agreements between LMUS and the OCAW and the UPGWA.

CERTAIN ARRANGEMENTS INVOLVING THE U.S. GOVERNMENT

Set forth below is a brief summary of certain of the more significant
arrangements between the U.S. Government and the Company.

51

53

The Government Oversight Committee.  In connection with the Privatization,
the U.S. Government established an enrichment oversight committee (the
"Oversight Committee") which monitors and coordinates U.S. Government efforts
with respect to the post-Privatization USEC in furtherance of:

- the full implementation of the government-to-government agreement
relating to the disposition of Russian HEU;

- the application of statutory, regulatory and contractual restrictions on
foreign ownership, control or influence of USEC;

- the development and implementation of U.S. Government policy regarding
uranium enrichment and related technologies, processes and data; and

- the collection and dissemination of information within the U.S.
Government relevant to the foregoing objectives.

On June 19, 1998, the Company entered into a memorandum of agreement with DOE
which established annual and quarterly reporting requirements for the Company in
support of the Oversight Committee's purposes.

Executive Agent Memorandum of Agreement.  USEC has been designated as the
Executive Agent of the United States under a government-to-government agreement
between the United States and the Russian Federation to purchase approximately
92 million SWU derived from 500 metric tons of HEU recovered from nuclear
weapons of the former Soviet Union for use in commercial electricity production.
Under the Executive Agent MOA, the Company can be terminated, or resign, as the
U.S. Executive Agent upon 30-days notice; however, the Company would nonetheless
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.

Liabilities Memorandum of Agreement.  The Privatization Act allocates the
responsibility for certain liabilities between the Company and the U.S.
Government, generally providing that liabilities arising from operations of the
Company after the Privatization are liabilities of the Company, and liabilities
attributable to operations of the Company and the predecessor government
agencies prior to the Privatization remain liabilities of the U.S. Government.
The one exception to this general allocation relates to certain liabilities of
the Company arising from operations between the Transition Date and the
Privatization that the Company retained pursuant to a memorandum of agreement
between the Company and the Office of Management and Budget.

Lease Agreement For Production Facilities.  The Company leases the GDPs from
DOE under the Lease Agreement for nominal rent, with options for indefinite
extensions. The Company also provides services to DOE for environmental
restoration, waste management and other activities at the GDPs for which it is
currently reimbursed at cost.

Treasury Agreement Regarding Ownership and Operation of the GDPs and Certain
Other Matters. The Company entered into the Treasury Agreement, pursuant to
which the Company made the following commitments, among others:

- to abide by the Privatization Act provisions, including the provision
which prohibits the sale of more than 10% of the outstanding voting stock
to any one person for a three-year period after the Privatization;

- not to sell or transfer all or substantially all of the uranium enrichment
assets or operations of the Company during the three-year period after the
Privatization;

- to the extent commercially practicable, to:

-- take steps reasonably calculated in good faith to ensure that
workforce reductions at the GDPs through fiscal year 2000 are
conducted in a manner consistent with the Company's strategic

52

54
plan, do not exceed 500 employees, and are effected in substantially
equal parts in each of fiscal years 1999 and 2000;

-- in each of fiscal years 1999 and 2000, seek to achieve such workforce
reductions through a program of voluntary separation before
instituting a program of involuntary separation; and

-- with respect to such workforce reductions, provide benefits and take
other measures to minimize workforce disruptions that are no less
favorable to the workforce than would have been the case prior to the
Privatization and that are in accordance with an agreement between the
Company and DOE concerning worker assistance; and

- to continue operation of the GDPs until at least January 1, 2005, subject
to the following exceptions:

-- the occurrence of any event beyond the reasonable control of USEC,
such as fires, floods, or acts of God, that prevents the continued
operation of a plant by USEC;

-- if the Operating Margin (as defined below) of USEC is less than 10% in
a twelve consecutive month period;

-- 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;

-- if the Operating Interest Coverage Ratio (as defined below) of USEC is
less than 2.5x in a twelve consecutive month period;

-- if there is a decrease in annual worldwide demand for SWU to less than
28 million SWU; or

-- if there is a decrease in the average price for all SWU under the
Company's long-term firm contracts to less than $80 per SWU (in 1998
dollars).

Operating Margin is defined in the Treasury Agreement to mean (x) earnings plus
interest, taxes and any extraordinary, nonrecurring charges divided by (y) total
revenue; Operating Interest Coverage Ratio is defined to mean (x) earnings plus
interest and taxes divided by (y) gross interest expense.

Pursuant to a requirement in the Treasury Agreement, USEC entered into an
agreement with its officers and directors whereby they agreed not to, and to use
their best efforts to cause their family members not to, acquire any Shares or
other securities convertible into or exchangeable for shares of Common Stock for
180 days following consummation of the IPO.

Electricity Memorandum of Agreement.  The Company entered into a memorandum
of agreement with DOE pursuant to which DOE transferred the benefits of its
power purchase agreements with EEI and OVEC to USEC, although DOE remains the
named purchaser under such power purchase agreements.

Certain Transfers from DOE.  Under the Privatization Act, DOE is required to
transfer to the Company, at no cost, up to 50 metric tons of HEU (representing
3.4 million SWU and 5,000 metric tons of natural uranium) and up to 7,000 metric
tons of natural uranium. The Company received the 7,000 metric tons of natural
uranium in April 1998, and expects to receive the 50 metric tons of HEU over the
period September 1998 to September 2003. In May 1998, the Company also received
an additional 3,800 metric tons of natural uranium and 45 metric tons of LEU
(representing 280,000 SWU and 453 metric tons of natural uranium) to settle
DOE's liabilities for certain nuclear safety upgrade costs and to satisfy
certain remaining obligations of DOE to the Company. See "Business -- Natural
Uranium and HEU from DOE."

Agreement Regarding AVLIS Research.  AVLIS research, development and
demonstration is conducted at LLNL under DOE's management and operations
contract with the University of California.

53

55

Inventions that result from the AVLIS research and development effort funded by
the Company will be owned by the Company. See "Business -- Advanced Laser-Based
Technology."

Depleted UF(6) Memorandum of Agreement.  The Company entered into a
memorandum of agreement with DOE pursuant to which title to depleted UF(6)
generated by USEC before the Privatization was transferred to DOE in accordance
with the Privatization Act.

DOE Agreement Regarding Depleted UF(6) Disposal.  The Company entered into
an agreement with DOE pursuant to which USEC has paid DOE $50.0 million and DOE
has assumed responsibility for a certain amount of depleted UF(6) generated by
the Company over the period from the Privatization Date to 2005.

EMPLOYMENT AND SEVERANCE AGREEMENTS

The Company is not a party to any employment or severance agreements.

SECURITY OWNERSHIP OF CERTAIN
BENEFICIAL OWNERS AND MANAGEMENT

None of the officers or directors of the Company currently owns any shares
of the Company's common stock. Pursuant to an agreement with the U.S. Treasury,
the officers and directors of the Company have agreed not to, and to use their
best efforts to cause their family members not to, acquire any shares or other
securities convertible into or exchangeable for shares of the Company's common
stock for 180 days following consummation of the IPO.

As of November 9, 1998, based solely upon a review of filings made by third
parties pursuant to Sections 13(d) and 13(g) of the Securities and Exchange Act
of 1934, as amended, there are no persons who beneficially own more than 5% of
the outstanding shares of common stock of the Company.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

In August 1998, the Company entered into an agreement with James R. Mellor,
the Chairman of the Board of Directors, under which Mr. Mellor will provide
certain consulting services to the Company. For the period from July 28, 1998
through July 27, 1999, Mr. Mellor will be paid $255,000 for his services under
the agreement.

DESCRIPTION OF THE NOTES

The Senior Notes are to be issued under an indenture to be dated as of
[                ], 1998 (the "Indenture") between the Company and First Union
National Bank, as trustee (the "Trustee"), a copy of which is filed as an
exhibit to the Registration Statement of which this Prospectus is a part. The
following summaries of certain provisions of the Indenture do not purport to be
complete, and are subject, and are qualified in their entirety by reference, to
all of the provisions of the Indenture, including the definitions therein of
certain terms.

GENERAL

The Senior Notes will be limited in aggregate principal amount to $[     ]
million and will mature on [     ], 200[  ]. The Senior Notes will bear interest
at the rate per annum shown on the front cover of this Prospectus from November
[     ], 1998 or from the most recent Interest Payment Date to which interest
has been paid or provided for, payable semi-annually on [     ] and [     ] of
each year, commencing [     ], 1999, to the Person in whose name the Senior Note
(or any predecessor Senior Note) is registered at the close of business on the
preceding [     ] or [     ], as the case may be. The Senior Notes will not be
subject to any sinking fund, but are subject to redemption at the option of the
Company as described below.

The Senior Notes will be unsecured obligations of the Company and will rank
on a parity with all other unsecured and unsubordinated indebtedness of the
Company. The Senior Notes effectively will be subordinated to all existing and
future third-party indebtedness and other liabilities of the Company's
subsidiaries (including trade payables). The Indenture does not limit the
Company's or its subsidiaries' ability to incur additional indebtedness.

OPTIONAL REDEMPTION

The Senior Notes will be redeemable 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 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.

If less than all of the Senior Notes are to be redeemed at any time,
selection of Senior Notes for redemption will be made by the Trustee on a pro
rata basis, by lot or by such method as the Trustee will deem fair and
appropriate; provided that no Senior Notes of $1,000 or less will be redeemed in
part. Notices of redemption will be mailed by first class mail at least 30 but
not more than 60 days before the Redemption Date to each Holder of Senior Notes
to be redeemed at its registered address. If any Senior Note is to be redeemed
in part only, the notice of redemption that relates to such Senior Note will
state the portion of the principal amount thereof to be redeemed. A new Senior
Note in principal amount equal to the unredeemed portion thereof will be issued
in the name of the Holder thereof upon cancellation of the original Senior Note.
On and after the Redemption Date, interest will cease to accrue on Senior Notes
or portions of them called for redemption unless the Company defaults in the
payment of the Redemption Price.

BOOK ENTRY PROCEDURES

Upon issuance, the Senior Notes will be represented by one or more fully
registered global notes (the "Global Notes"). Each such Global Note will be
deposited with, or on behalf of, The Depository Trust Company, as Depositary,
and registered in the name of the Depositary or a nominee thereof. The
Depositary will maintain the Senior Notes in denominations of $1,000 and
integral multiples thereof through its book-entry facilities. Unless and until
it is exchanged in whole or in part for Senior Notes in definitive form, no
Global Note may be transferred except as a whole by the Depositary to a nominee
of such Depositary or by a nominee of such Depositary to such Depositary.

61

63

Ownership of beneficial interests in Senior Notes will be limited to Persons
that have accounts with the Depositary ("Participants") or Persons that may hold
interests through Participants. Upon the issuance of Global Notes, the
Depositary will credit, on its book-entry registration and transfer system, the
Participants' accounts with the respective principal amounts of such Senior
Notes beneficially owned by such Participants. Ownership of beneficial interests
in such Global Note will be shown on, and the transfer of such ownership
interests will be effected only through, records maintained by the Depositary or
its nominee (with respect to interests of Participants) and on the records of
Participants (with respect to interests of persons holding through
Participants). The laws of some states may require that certain purchasers of
securities take physical delivery of such securities in definitive form. Such
limits and such laws may impair the ability to own, transfer or pledge
beneficial interests in Global Notes.

So long as the Depositary, or its nominee, is the registered owner of a
Global Note, the Depositary or its nominee, as the case may be, will be
considered the sole owner or Holder of Senior Notes represented by such Global
Note for all purposes under the Indenture. Except as provided below, owners of
beneficial interests in a Global Note will not be entitled to have the Senior
Notes represented by such Global Notes registered in their names, will not
receive or be entitled to receive physical delivery of such Senior Notes in
definitive form and will not be considered the owners or Holders thereof under
the Indenture. Accordingly, each Person owning a beneficial interest in a Global
Note must rely on the procedures of the Depositary and, if such Person is not a
Participant, on the procedures of the Participant through which such Person owns
its interest, to exercise any rights of a Holder under the Indenture. The
Company understands that under existing industry practices, in the event that
the Company requests any actions of Holders or that an owner of a beneficial
interest in such a Global Note desires to give or take any action which a Holder
is entitled to give or take under the Indenture, the Depositary would authorize
the Participants holding the relevant beneficial interests to give or take such
action, and such Participants would authorize beneficial owners owning through
such Participants to give or take such action or would otherwise act upon the
instructions of beneficial owners holding through them.

Payment of principal of, premium, if any, and interest on, Senior Notes
registered in the name of the Depositary or its nominee will be made to the
Depositary or its nominee, as the case may be, as the Holder of the Global Notes
representing such Senior Notes. None of the Company, the Trustee or any other
agent of the Company or agent of the Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on account
of beneficial ownership interests or for supervising or reviewing any records
relating to such beneficial ownership interests. The Company expects that the
Depositary, upon receipt of any payment of principal or interest in respect of a
Global Note, will credit the accounts of the Participants with payment in
amounts proportionate to their respective beneficial interests in such Global
Note as shown on the records of the Depositary. The Company also expects that
payments by Participants to owners of beneficial interests in a Global Note will
be governed by standing customer instructions and customary practices, as is now
the case with securities held for the accounts of customers in bearer form or
registered in "street name," and will be the responsibility of such
Participants.

The Depositary has advised the Company as follows: the Depositary is a
limited-purpose trust company organized under the Banking Law of the State of
New York, a member of the Federal Reserve System, a "clearing corporation"
within the meaning of the New York Uniform Commercial Code, and a "clearing
agency" registered pursuant to the provisions of Section 17A of the Exchange
Act. The Depositary was created to hold securities of its Participants and to
facilitate the clearance and settlement transactions among its Participants in
such securities through electronic book-entry changes in accounts of the
Participants, thereby eliminating the need for physical movement of securities
certificates. The Participants include securities brokers and dealers (including
the Underwriters), banks, trust companies, clearing corporations, and certain
other organizations, some of whom (and/or their representatives) own the
Depositary. Access to the Depositary's book-entry system is also available to
others, such as banks, brokers, dealers and trust companies that clear through
or maintain a custodial relationship with a Participant, either directly or
indirectly. Persons who are not Participants may beneficially own securities
held by the Depositary only through Participants.

62

64

If the Depositary is at any time unwilling or unable to continue as
Depositary or the Depositary ceases to be a clearing agency registered under the
Exchange Act and a successor Depositary registered as a clearing agency under
the Exchange Act is not appointed by the Company in 90 days, then upon
notification to the Trustee, the Global Notes will, upon surrender thereof by
the Depositary, be transferable or exchangeable for Senior Notes in definitive
form of like tenor and of an equal aggregate principal amount, in denominations
of $1,000 and integral multiples thereof. Such definitive Senior Notes shall be
registered in such name or names, and issued to such Person or Persons, in each
case as the Depositary shall identify to the Trustee as the beneficial owners of
the Senior Notes. It is expected that such instructions may be based upon
directions received by the Depositary from Participants with respect to
ownership of beneficial interests in such Global Notes. None of the Company, the
Trustee or any other agent of the Company or agent of the Trustee will have any
liability for any delay by the Depositary in identifying the beneficial owners
of the Senior Notes, and each such Person may conclusively rely on and shall be
protected in relying on, instruction from the Depositary for all purposes
(including with respect to registration and delivery, and the respective
principal amount, of the Senior Notes to be issued).

SAME-DAY SETTLEMENT AND PAYMENT

Settlement for the Senior Notes will be made in immediately available funds.
So long as the Senior Notes are subject to the Depositary's book-entry system,
the Senior Notes will trade in the Depositary's Same-Day Funds Settlement System
until maturity, and therefore the Depositary will require that secondary trading
activity be settled in immediately available funds. No assurance can be given as
to the effect, if any, of settlement in immediately available funds on trading
activity in the Senior Notes.

LIMITATION ON LIENS

The Indenture will provide that the Company will not, and will 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
Senior Notes) without effectively providing that the Senior Notes 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
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,

63

65

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 Senior Notes) that is not excepted by clauses (a) through (f) (inclusive)
above without securing the Senior Notes, 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 (a) through (c) (inclusive) of the covenant
below entitled "Limitation on Sale-Leaseback Transactions") would not exceed 10%
of Consolidated Net Tangible Assets.

LIMITATION ON SALE-LEASEBACK TRANSACTIONS

The Indenture will provide that the Company will not, nor will 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 Senior Notes
pursuant to the above covenant entitled "Limitation on Liens"; 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 Property so
leased) from such Sale-Leaseback Transaction to (i) the prepayment, repayment,
reduction or retirement of any pari passu Funded Debt or 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.

with such a constant maturity for which a closing yield is given, the Treasury
Yield shall be obtained by linear interpolation (calculated to the nearest
one-twelfth of a year) from the closing yields of United States Treasury
securities for which such yields are given, except that if the remaining
maturity of such Senior Note is less than one year, the weekly average yield on
actually traded United States Treasury securities adjusted to a constant
maturity of one year shall be used.

CONSOLIDATION, MERGER AND SALE OF ASSETS

The Company may consolidate with or merge into, or convey, transfer or lease
its properties and assets substantially as an entirety to, any Person, provided
that (i) the Company is the continuing entity or if the Company is not the
continuing entity, the continuing entity must be a Person organized and validly
existing under the laws of a domestic jurisdiction and must assume the Company's
obligations on the Senior Notes and under the Indenture, (ii) after giving
effect to the transaction no Event of Default, and no event which, after notice
or lapse of time or both, would become an Event of Default, shall exist and
(iii) the Company has delivered to the Trustee an Officer's Certificate and
Opinion of Counsel, each stating that the transaction complies with these
conditions.

EVENTS OF DEFAULT

Each of the following will constitute an Event of Default under the
Indenture: (a) failure to pay principal of or any premium on any Senior Note
when due; (b) failure to pay any interest on any Senior Note when due, continued
for 30 days; (c) failure to perform any other covenant of the Company or its
Subsidiaries in the Senior Notes or Indenture, continued for 60 days after
written notice has been given by the Trustee, or the Holders of at least 25% in
principal amount of the then outstanding Senior Notes, as provided in the
Indenture; (d) a 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 thereafter be created, having an aggregate
principal amount exceeding $[ ] million (or its equivalent in any other currency
or currencies), other than the Senior Notes, 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,
originally applicable thereto and the time for payment of such amount has not
been expressly extended; and (e) certain events in bankruptcy, insolvency or
reorganization of the Company or any of its Subsidiaries.

If an Event of Default (other than an Event of Default described in clause
(e) above) with respect to any of the Senior Notes shall occur and be
continuing, either the Trustee or the Holders of at least 25% of the then
outstanding Senior Notes by notice to the Company as provided in the Indenture
may declare the principal amount of Senior Notes to be due and payable
immediately. If an Event of Default described in clause (e) above shall occur,
the principal amount of all the then outstanding Senior Notes will
automatically, and without any action by the Trustee or any Holder, become
immediately due and payable. After any acceleration, but before a judgment or
decree for the payment of the money due has been obtained by the Trustee, the
Holders of a majority in aggregate principal amount of the then outstanding
Senior Notes, by written notice to the Trustee, may rescind and annul such
acceleration and its consequences if all Events of Default, other than the
non-payment of accelerated principal, have been

66

68

cured or waived as provided in the Indenture. For information as to waiver of
defaults, see "--Modification and Waiver".

Subject to the provisions of the Indenture relating to the duties of the
Trustee in case an Event of Default shall occur and be continuing, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the Holders of the Senior Notes,
unless such Holders of the Senior Notes shall have offered to the Trustee
reasonable indemnity. Subject to such provisions for the indemnification of the
Trustee, the Holders of a majority in aggregate principal amount of the then
outstanding Senior Notes will have the right to 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 with respect to such
Senior Notes.

No Holder of any Senior Note will have any right to institute any proceeding
with respect to the Indenture, or for the appointment of a receiver or a
trustee, or for any other remedy thereunder, unless (i) such Holder has
previously given to the Trustee written notice of a continuing Event of Default
with respect to the Senior Notes, (ii) the Holders of at least 25% in aggregate
principal amount of the then outstanding Senior Notes have made written request,
and such Holder or Holders have offered reasonable indemnity, to the Trustee to
institute such proceeding in respect to such Event of Default as trustee and
(iii) the Trustee has failed to institute such proceeding, and has not received
from the Holders of a majority in aggregate principal amount of the then
outstanding Senior Notes a direction inconsistent with such request, within 60
days after such notice, request and offer. However, such limitations do not
apply to any proceeding which is instituted by a Holder of a Senior Note for the
enforcement of payment of the principal of or interest on such Senior Note on or
after the applicable due date specified in such Senior Note.

The Company will be required to furnish to the Trustee annually a statement
by certain of its officers as to whether or not the Company or any of its
Subsidiaries, to their knowledge, is in default in the performance or observance
of any of the terms, provisions and conditions of the Indenture and, if so,
specifying all such known defaults.

MODIFICATION AND WAIVER

Modifications and amendments of the Indenture may be made by the Company and
the Trustee with the consent of the Holders of a majority in principal amount of
the then outstanding Senior Notes; provided, however, that no such modification
or amendment may, without the consent of the Holder of each Senior Note affected
thereby, (a) change the Stated Maturity of the principal of, or any installment
of principal of or interest on, any such Senior Note, (b) reduce the principal
amount of, or any interest on, any such Senior Note, (c) reduce the amount of
principal of any such Senior Note payable upon acceleration of the Maturity
thereof, (d) change the place or currency of payment of principal of, or
interest on, any such Senior Note, (e) impair the right to institute suit for
the enforcement of any payment on or with respect to any such Senior Note, (f)
reduce the percentage in principal amount of such Senior Note, the consent of
whose Holders is required for modification or amendment of the Indenture, (g)
reduce the percentage in principal amount of such Senior Note necessary for
waiver of compliance with certain provisions of the Indenture or for waiver of
certain defaults or (h) modify such provisions with respect to modification and
waiver.

The Holders of a majority in principal amount of the then outstanding Senior
Notes may waive compliance by the Company or any of its Subsidiaries with
certain restrictive provisions of the Indenture or waive any past default under
the Indenture, except a continuing default in the payment of principal of or
interest on such Senior Notes and covenants and provisions of the Indenture that
under the proviso in the preceding paragraph cannot be amended without the
consent of the Holder of each Senior Note affected thereby.

The Indenture provides that in determining whether the Holders of the
requisite principal amount of the Senior Notes have given or taken any
direction, notice, consent, waiver or other action under the

67

69

Indenture as of any date, certain Senior Notes, including those that have been
defeased and discharged as described under "-- Satisfaction and Discharge;
Defeasance -- Defeasance and Discharge" will not be deemed to be outstanding.

Except in certain limited circumstances, the Company will be entitled to set
any day as a record date for the purpose of determining the Holders of Senior
Notes entitled to give or take any direction, notice, consent, waiver or other
action under the Indenture, in the manner and subject to the limitations
provided in the Indenture. In certain limited circumstances, the Trustee also
will be entitled to set a record date for action by Holders of Senior Notes. If
a record date is set for any action to be taken by Holders of the Senior Notes,
such action may be taken only by persons who are Holders of such Senior Notes on
the record date. To be effective, such action must be taken by Holders of the
requisite principal amount of the Senior Notes within a specified period
following the record date. For any particular record date, this period will be
180 days or such shorter period as may be specified by the Company (or the
Trustee, if it sets the record date), and may be shortened or lengthened (but
not beyond 180 days) from time to time.

SATISFACTION AND DISCHARGE; DEFEASANCE

Satisfaction and Discharge. The Indenture will provide that the Company may
satisfy and discharge certain obligations to Holders of Senior Notes which have
not already been delivered to the Trustee for cancellation and which have either
become due and payable or are by their terms due and payable within one year or
are to be called for redemption within one year by (a) depositing or causing to
be deposited with the Trustee funds in an amount sufficient to pay the principal
and any premium and interest to the date of such deposit or to the Stated
Maturity or any applicable redemption date, as the case may be, (b) paying or
causing to be paid all other sums payable under the Indenture with respect to
such Senior Notes, and (c) delivering to the Trustee an Officer's Certificate
relating to such satisfaction and discharge.

Defeasance and Discharge. The Indenture will provide that the Company will
be discharged from all its indebtedness and obligations with respect to Senior
Notes (except for certain obligations to exchange or register the transfer of
such outstanding Senior Notes, to replace stolen, lost or mutilated outstanding
Senior Notes, to maintain paying agencies and to hold moneys for payment in
trust) upon the deposit in trust for the benefit of the Holders of such
outstanding Senior Notes of money or U.S. Government Obligations, or both,
which, through the payment of principal and interest in respect thereof in
accordance with their terms, will provide money in an amount sufficient to pay
the principal of and interest on such outstanding Senior Notes at Maturity in
accordance with the terms of the Indenture and such outstanding Senior Notes.
Such defeasance or discharge may occur only if, among other things, the Company
has delivered to the Trustee an Opinion of Counsel to the effect that the
Company has received from, or there has been published by, the United States
Internal Revenue Service a ruling, or there has been a change in tax law, in
either case to the effect that Holders of such outstanding Senior Notes will not
recognize gain or loss for federal income tax purposes as a result of such
deposit, defeasance and discharge and will be subject to federal income tax on
the same amount, in the same manner and at the same times as would have been the
case if such deposit, defeasance and discharge were not to occur.

Defeasance of Certain Covenants. The Indenture will provide that the Company
and its Subsidiaries may omit to comply with certain restrictive covenants,
including the covenants described under "Limitation on Liens", "Limitation on
Sale-Leaseback Transactions" and "Consolidation, Merger and Sale of Assets", in
which event certain Events of Default, which are described above in clause (c)
(with respect to such respective covenants) under "Events of Default", will no
longer constitute Events of Default with respect to the Senior Notes. The
Company, in order to exercise such option to defease such covenants, will be
required to deposit, in trust for the benefit of the Holders of outstanding
Senior Notes, money or U.S. Government Obligations, or both, which, through the
payment of principal and interest in respect thereof in accordance with their
terms, will provide money in an amount sufficient to pay the principal of and
interest on such Senior Notes at Maturity in accordance with the terms of the
Indenture and such outstanding Senior Notes. The Company will also be required,
among other things, to deliver to the Trustee an Opinion of Counsel to the
effect that Holders of such outstanding Senior Notes will not recognize gain or
loss for

68

70

federal income tax purposes as a result of such deposit and defeasance of
certain obligations and will be subject to federal income tax on the same
amount, in the same manner and at the same times as would have been the case if
such deposit and defeasance were not to occur.

If subsequent to the completion of a defeasance of certain covenants as
described in the immediately preceding paragraph, such outstanding Senior Notes
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 so deposited in
trust would be sufficient to pay amounts due on such Senior Notes at Maturity
but may not be sufficient to pay amounts due on such Senior Notes upon any
acceleration resulting from such Event of Default, then the Company would remain
liable for such payments.

NOTICES

Notices to Holders of the Senior Notes will be given by mail to the
addresses of such Holders as they may appear in the Security Register.

TITLE

The Company, the Trustee and any agent of the Company or the Trustee may
treat the Person in whose name a Senior Note is registered as the absolute owner
thereof (whether or not the Senior Notes may be overdue) for the purpose of
making payment and for all other purposes.

GOVERNING LAW

The Indenture and the Senior Notes will be governed by, and construed in
accordance with, the laws of the State of New York.

UNDERWRITING

Subject to the terms and conditions set forth in a purchase agreement (the
"Purchase Agreement") among the Company and Merrill Lynch, Pierce, Fenner &
Smith Incorporated and J.P. Morgan Securities Inc. (the "Underwriters"), the
Company has agreed to sell to the Underwriters, and the Underwriters have
severally agreed to purchase, the respective principal amounts of the Senior
Notes set forth after their names below. The Purchase Agreement provides that
the obligations of the Underwriters are subject to certain conditions precedent
and that the Underwriters will be obligated to purchase all of the Senior Notes
if any are purchased.

==============

The Underwriters have advised the Company that they propose initially to
offer the Senior Notes to the public at the public offering prices set forth on
the cover page of this Prospectus, and to certain dealers at such prices less a
concession not in excess of [ ]% of the principal amount of the Senior Notes.
The Underwriters may allow, and such dealers may reallow, discounts not in
excess of [ ]% of the principal amount of the Senior Notes, to certain other
dealers. After the initial offering of the Senior Notes, the public offering
price, concession and discount may be changed.

The Senior Notes are a new issue of securities with no established trading
market. The Company does not intend to apply for listing of the Senior Notes on
any national securities exchange but has been advised by the Underwriters that
they presently intend to make a market in the Senior Notes as permitted by
applicable laws and regulations. The Underwriters are not obligated, however, to
make a market in the Senior Notes and any such market making may be discontinued
at any time at the sole discretion of the Underwriters. Accordingly, no
assurance can be given as to the trading market for the Senior Notes.

In order to facilitate the offering of the Senior Notes, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Senior Notes. Such transactions may consist of bids or purchases
for the purpose of pegging, fixing or maintaining the price of the Senior Notes.
If the Underwriters create a short position in the Senior Notes in connection
with the offering, i.e., if they sell more Senior Notes than are set forth on
the cover page of this Prospectus, the Underwriters may reduce that short
position by purchasing Senior Notes in the open market. In general, purchases of
a security for the purpose of stabilization or to reduce a short position could
cause the price of the security to be higher than it might be in the absence of
such purchases. The Underwriters may also impose a penalty bid on certain
Underwriters and any selling group members. This means that if the Underwriters
purchase Senior Notes in the open market to reduce the Underwriters' short
position or to stabilize the price of the Senior Notes, they may reclaim the
amount of the selling concession from the Underwriters and any selling group
members who sold those Senior Notes as part of the offering. The imposition of a
penalty bid might also have an effect on the price of the Senior Notes to the
extent it were to discourage resales of the Senior Notes.

Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Senior Notes. In addition, neither
the Company nor any of the Underwriters makes any representation that the
Underwriters will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.

The Company has agreed to indemnify the Underwriters against certain
liabilities (including reimbursements to the Underwriters for certain fees and
expenses of their counsel), including civil

70

72

liabilities under the Securities Act of 1933, as amended, or to contribute to
payments the Underwriters may be required to make in respect of such
liabilities.

A portion of the net proceeds from the sale of the Senior Notes is expected
to be used to repay outstanding borrowings under the Credit Facility under which
Morgan Guaranty is a lender. Morgan Guaranty is an affiliate of J.P. Morgan
Securities Inc., an underwriter of this offering.

In the ordinary course of their respective businesses, the Underwriters or
their affiliates have performed, and may in the future perform, investment
banking, commercial banking or other financial services for the Company.

LEGAL MATTERS

The validity of the issuance of the Senior Notes offered hereby will be
passed upon for the Company by Skadden, Arps, Slate, Meagher & Flom LLP,
Washington, D.C., special counsel for the Company, and for the Underwriters by
Davis Polk & Wardwell, New York, New York.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of USEC Inc.:

We have audited the accompanying balance sheets of USEC Inc., a Delaware
corporation, (formerly United States Enrichment Corporation) as of June 30, 1997
and 1998, and the related statements of income and cash flows for each of the
three years in the period ended June 30, 1998. 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,
1997 and 1998, and the results of its operations and its cash flows for each of
the years in the three year period ended June 30, 1998, in conformity with
generally accepted accounting principles.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors of USEC Inc.:

We have examined the pro forma adjustments (not separately presented)
reflecting the IPO Transactions as described in Note 4 and the application of
those adjustments to the historical amounts in the assembly of the accompanying
pro forma statement of income of USEC Inc. (the "Company") for the year ended
June 30, 1998. The pro forma statement of income is derived from the audited
historical statement of income of USEC Inc. appearing herein. Such pro forma
adjustments are based upon management's assumptions described in Note 4. Our
examination was made in accordance with standards established by the American
Institute of Certified Public Accountants and, accordingly, included such
procedures as we considered necessary in the circumstances.

The objective of the pro forma statement of income is to show what the
significant effects on the historical statement of income might have been had
the IPO Transactions occurred at an earlier date. However, the pro forma
statement of income is not necessarily indicative of the results of operations
that would have been attained had the IPO Transactions actually occurred
earlier.

In our opinion, management's assumptions provide a reasonable basis for
presenting the significant effects directly attributable to the IPO
Transactions, the related pro forma adjustments give appropriate effect to those
assumptions, and the pro forma statement of income reflects the proper
application of those adjustments to the historical statement of income for the
year ended June 30, 1998.

NOTES TO FINANCIAL STATEMENTS

1. NATURE OF OPERATIONS

USEC Inc., a Delaware-chartered corporation (the "Company" or "USEC"),
formerly United States Enrichment Corporation (a federal-chartered U.S.
Government-owned corporation), is a global energy company and the world's
leading producer and marketer of uranium enrichment services. The Company
provides uranium enrichment services to electric utilities operating nuclear
reactors in 14 countries, including the United States. The Company 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 HEU Contract")
under which the Company purchases Separative Work Units ("SWU") derived from
highly enriched uranium ("HEU") recovered from dismantled nuclear weapons of the
Russian Federation for use in commercial electricity production.

The Company 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 ("GDPs") 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 GDPs is supplied under
power contracts between the U.S. Department of Energy ("DOE") and Ohio Valley
Electric Corporation ("OVEC") and Electric Energy, Inc. ("EEI"). Lockheed Martin
Utility Services, Inc. ("LMUS"), a subsidiary of Lockheed Martin Corporation,
operates the GDPs under the Company's direct supervision and management.

In November 1996, the Nuclear Regulatory Commission ("NRC") granted initial
certificates of compliance to the Company for operation of the GDPs. Regulatory
authority over the operations of the GDPs was transferred from DOE to NRC in
March 1997. The initial NRC certification expires December 31, 1998, and
subsequent certification will be for periods of up to five years.

Customers typically deliver uranium to the enrichment facilities to be
processed or enriched under enrichment contracts. Customers are billed for 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 UF(6) having a lower percentage of U(235).

The Company has exclusive commercial rights to deploy the Atomic Vapor
Laser Isotope Separation ("AVLIS") technology, an advanced laser based
enrichment process that is expected to significantly reduce production costs.
USEC anticipates deploying an AVLIS plant by 2005.

2. INITIAL PUBLIC OFFERING

On July 28, 1998, the sale of the Company's common stock in connection with
an initial public offering (the "IPO") was completed, resulting in net proceeds
to the U.S. Government aggregating $3,092.1 million, including $1,382.7 million
from the IPO and $1,709.4 million from the exit dividend paid to the U.S.
Treasury (the "Exit Dividend"). The U.S. Government, the selling shareholder,
sold its entire interest. The Company did not receive any proceeds from the IPO.

The Exit Dividend of $1,709.4 million paid to the U.S. Treasury represented
the cash balance held in the Company's account at the U.S. Treasury and $500.0
million of $550.0 million in borrowings at the time of the IPO. The Company
retained $50.0 million in cash from the $550.0 million in borrowings. The amount
of the Exit Dividend in excess of the Company's retained earnings was recorded
in July 1998 as a reduction of excess of capital over par value.

Pursuant to the USEC Privatization Act, depleted uranium hexafloride
("UF(6)") generated by the Company through the date of the IPO was transferred
to DOE in July 1998; liabilities and contingencies

F-7

USEC INC.

NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

incurred through the date of the IPO were allocated between the Company and the
U.S. Government; 50 metric tons of HEU and 7,000 metric tons of natural uranium
from DOE's excess inventories were transferred to the Company in May 1998;
certain employee benefit protections were established for workers at the GDPs;
certain limitations were established on the ability of a person to acquire more
than 10% of the Company's voting securities for a three-year period after the
IPO; and certain foreign ownership limitations were established.

The U.S. Government will continue to exercise oversight of the Company's
activities affecting matters of national security and other interests of the
U.S. Government, including its role as Executive Agent in connection with the
Russian HEU Contract.

3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CASH

Cash at June 30, 1997 and 1998 consists of non-interest bearing funds on
deposit with the U.S. Treasury.

INVENTORIES

Inventories of uranium and SWU are valued at the lower of cost or market.
SWU inventory costs are determined using the monthly moving average cost method
and are based on production costs at the GDPs and SWU purchase costs, mainly
under the Russian HEU Contract. Production costs at the GDPs include purchased
electric power, labor and benefits, depleted UF(6) disposition costs, materials,
major overhauls, 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 GDP lease period which is
estimated to extend through 2005. The Company leases the GDPs and
process-related machinery and equipment from DOE. At the end of the lease term,
ownership and responsibility for decontamination and decommissioning of the
Company's property, plant and equipment that the Company leaves at the GDPs
transfer to DOE.

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

1997      1998
------    ------

Construction work in progress...............................  $ 15.6    $ 27.1

REVENUE

Revenue is recognized at the time enriched uranium is shipped under the
terms of long-term requirements contracts with domestic and foreign electric
utility customers. Under the Company's delivery

F-8

81
USEC INC.

NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

optimization and other customer oriented programs, the Company 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, the Company exchanges its enrichment
services for electric power supplied to the GDPs. Revenue is recognized by the
Company 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, 1996, 1997 or 1998. Revenue attributed to domestic and international
customers follows:

YEARS ENDED JUNE 30,
--------------------
1996    1997    1998
----    ----    ----

Domestic....................................................   64%     60%     63%
Asia........................................................   31      31      31
Europe and other............................................    5       9       6
---     ---     ---
100%    100%    100%
===     ===     ===

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.

ENVIRONMENTAL COSTS

Environmental costs relating to operations are charged to production costs
as incurred. Estimated future environmental costs, including depleted UF(6)
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 AVLIS project. 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. The Company intends to
capitalize AVLIS development costs associated with facilities and equipment
designed for commercial production activities.

INCOME TAXES

The Company was exempt from income taxes up to the time of the IPO. The
Company transitioned to taxable status on July 28, 1998, at the time of the IPO.
Future tax consequences of temporary differences between the carrying amounts
for financial reporting purposes and the Company'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 any contingent assets and liabilities at the date of the financial
statements, and reported amounts of revenue and costs and expenses during the
periods presented such as, but not limited to, accrued costs for the disposition
of depleted UF(6) and the operating lease period of the GDPs. Actual results
could differ from those estimates.

INTERIM FINANCIAL STATEMENTS

The unaudited financial statements as of and for the three months ended
September 30, 1998, included herein have been prepared by the Company pursuant
to the rules and regulations of the Securities and Exchange Commission. The
interim financial statements reflect all adjustments which are, in the opinion
of management, necessary for a fair statement of the financial results for the
interim period. Operating results for the three months ended September 30, 1998,
are not necessarily indicative of the results that may be expected for the year
ending June 30, 1999.

RECLASSIFICATIONS

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

4. PRO FORMA STATEMENT OF INCOME

The pro forma statement of income for the year ended June 30, 1998,
reflects the sale of 100 million shares of Common Stock in connection with the
Company's IPO, interest expense on borrowings from banks, and the Company's
transition to taxable status at the time of the IPO (the "IPO Transactions").
The objective of the pro forma statement of income is to show the significant
effects of the IPO Transactions as if the IPO had occurred at the beginning of
the year ended June 30, 1998.

Pro forma interest expense of $36.0 million is based on a weighted average
interest rate of 6.55% on $550.0 million of borrowings incurred at the time of
the IPO, as if such borrowings had occurred at the beginning of the fiscal year
ended June 30, 1998.

The Company was exempt from federal, state and local income taxes until the
time of the IPO. The pro forma provision for income taxes of $41.9 million is
based on an effective income tax rate of 38% and assumes the IPO had occurred at
the beginning of the fiscal year ended June 30, 1998.

Pro forma basic net income per share is based on 100 million shares of
common stock sold in the IPO. The U.S. Government sold its entire interest in
the Company. At the time of the IPO, there were no stock options, warrants or
convertible securities, and, accordingly, pro forma basic and diluted net income
per share are the same.

NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

Inventories included in current assets represent amounts required to meet
working capital needs, preproduce enriched uranium and balance the natural
uranium and electric power requirements of the GDPs, and include $157.9 million
and $187.6 million at June 30, 1997 and 1998, respectively, for enriched uranium
held at fabricators and other locations and scheduled to be used to fill
customer orders.

Uranium inventories reported as long-term assets represent quantities not
expected to be used or consumed within one year of the balance sheet date.

Uranium provided by customers for enrichment purposes, for which title
passes to the Company, is recorded at estimated fair values of $726.2 million
and $315.0 million at June 30, 1997 and 1998, with a corresponding liability in
the same amount representing uranium owed to customers. In addition, the Company
holds uranium provided by customers for enrichment purposes for which title does
not pass to the Company (title remains with customers) in the amounts of $110.5
million and $761.9 million based on estimated fair values at June 30, 1997 and
1998, respectively.

6. PURCHASE OF SEPARATIVE WORK UNITS UNDER RUSSIAN HEU CONTRACT

In January 1994, the Company signed the 20-year Russian HEU Contract with
Techsnabexport Co., Ltd. (TENEX), the Executive Agent for the Russian
Federation, under which the Company purchases SWU derived from up to 500 metric
tons of HEU recovered from dismantled Soviet nuclear weapons. HEU is blended
down in Russia and delivered to the Company, F.O.B. St. Petersburg, Russia, for
sale and use in commercial nuclear reactors.

From inception of the Russian HEU Contract to June 30, 1998, the Company
purchased 7.4 million SWU derived from 40 metric tons of HEU at an aggregate
cost of $639.9 million, including related shipping charges, as follows:

SWU     COST
---    ------
(MILLIONS)

YEARS ENDED JUNE 30,

---    ------
7.4    $639.9
===    ======

Subject to certain purchase price adjustments for U.S. inflation, as of
June 30, 1998, the Company has committed to purchase SWU derived from HEU
through 2001 as follows:

DERIVED FROM
CALENDAR YEAR                       SWU       METRIC TONS OF HEU     AMOUNT

--------
$1,736.2
========

Over the life of the Russian HEU Contract, the Company expects to purchase
92 million SWU derived from 500 metric tons of HEU. Assuming actual prices in
effect at June 30, 1998, were to prevail over the remaining life of the
contract, the cost of SWU purchased and expected to be purchased from TENEX
would amount to approximately $8 billion.

F-11

84
USEC INC.

NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

As of June 30, 1998, the Company had made payments aggregating $260.0
million to TENEX as credits for future SWU deliveries. As of June 30, 1998,
$196.6 million had been applied against purchases of SWU, and the remaining
balance of $63.4 million is scheduled to be applied as follows: $13.4 million by
December 31, 1998, and $50.0 million in calendar year 1999.

7. INCOME TAXES

The Company was exempt from income taxes up to the time of the IPO. The
Company transitioned to taxable status on July 28, 1998, at the time of the IPO.
Future tax consequences of temporary differences between the carrying amounts
for financial reporting purposes and the Company's estimate of the tax bases of
its assets and liabilities resulted in deferred income tax benefits of $54.5
million at the time of the IPO as follows: $17.3 million for SWU and uranium
inventory costs, $9.0 million for GDP lease turnover costs, $7.8 million for
contractor pension costs, $6.9 million for decommissioning and shutdown costs at
dedicated electric power generation facilities, and $13.5 million for other
temporary differences relating primarily to other liabilities.

8. DEBT

On July 28, 1998, at the time of the IPO, the Company borrowed $550.0
million in variable rate debt under a credit facility comprised of three
tranches (the "Credit Facility"). Tranche A is a 364-day revolving credit
facility for $400.0 million. Tranche B is a 364-day revolving credit facility
for $150.0 million which is convertible, at the Company's option, into a
one-year term loan. Tranche C is a five-year revolving credit facility for
$150.0 million for working capital and general corporate purposes. Borrowings
under the Credit Facility amounted to $565.0 million at September 30, 1998, of
which $265.0 million was classified as short-term debt. Interest is paid at a
rate equal to, at the Company's option (i) the London Interbank Offered Rate
("LIBOR") plus an "Applicable Eurodollar Margin" or (ii) the Base Rate (as
defined). The Applicable Eurodollar Margin is based on the Company's credit
rating. The weighted average interest rate for borrowings under the Credit
Facility, including the amortization of fees, amounted to 6.8% (unaudited) for
the period ended September 30, 1998.

The Credit Facility requires the Company 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, including
restrictions on borrowings by subsidiaries. The failure to satisfy any of the
covenants would constitute an event of default. The Credit Facility also
includes other customary events of default, including without limitation,
nonpayment, material misrepresentations, cross-default to other indebtedness,
bankruptcy, and change of control.

9. PROJECT DEVELOPMENT COSTS

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 April 1995, the Company entered into an agreement with DOE (the "AVLIS
Transfer Agreement") providing for, among other things, the transfer to the
Company by DOE of its intellectual and physical property pertaining to the AVLIS
technology. Also under the AVLIS Transfer Agreement, DOE conducts AVLIS
research, development and demonstration at LLNL as requested by the Company. The
Company reimburses DOE for its costs in conducting AVLIS work, and the Company
is liable for any incremental increase in DOE's costs of decontamination and
decommissioning the AVLIS facilities at LLNL as a result of the work performed
for the Company. The AVLIS research and development work is performed primarily
by the University of California under DOE's management and operations contract
for

F-12

85
USEC INC.

NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

LLNL. Patents, technology, and other intellectual property that result from this
research and development effort will be owned by the Company.

The Company has entered into joint development agreements with Cameco
Corporation ("Cameco") for AVLIS feed conversion services and General Electric
Company ("GE") for AVLIS product conversion services, both of which are
necessary because AVLIS requires a metallic form of uranium for processing
rather than UF(6). However, USEC is investigating a product conversion process
using UF(6) with another commercial vendor. Both joint development agreements
with Cameco and GE obligate USEC to reimburse costs and expenses incurred by its
partners if USEC elects not to proceed to the deployment phase under certain
circumstances. The Company's maximum liability under both agreements is $9.0
million, subject to certain provisions for cost overruns. The contracts also
provide that if USEC proceeds with AVLIS deployment but elects to do so without
entering into agreements with Cameco and GE, USEC must pay certain royalty
payments. In such event, in the case of Cameco, these payments would not exceed
$50.0 million in the aggregate. In the case of GE, the payment would include a
fixed payment of $5.0 million plus an annual royalty of $1.0 million until
certain GE patents related to the product conversion expire.

Project development costs relating to AVLIS activities amounted to $102.0
million, $133.7 million, and $134.7 million for the years ended June 30, 1996,
1997 and 1998, respectively, and were charged to expense as incurred.

During the year ended June 30, 1997, the Company began to evaluate SILEX, a
potential new advanced enrichment technology to separate U(235) from U(238). The
Company plans to continue evaluating SILEX technology during fiscal 1999.

10. ENVIRONMENTAL MATTERS

Environmental compliance costs include the handling, treatment and disposal
of hazardous substances and wastes. Pursuant to the Privatization Act, all
environmental liabilities associated with the operation of the GDPs prior to
July 1, 1993, are the responsibility of DOE, and with certain limited exceptions
DOE is responsible for decontamination and decommissioning of the GDPs at the
end of their operating lives. Except for certain liabilities relating to
disposal of certain wastes generated after July 1, 1993, all environmental
liabilities of the Company through the date of the IPO remain obligations of the
U.S. Government.

DEPLETED UF(6)

Depleted UF(6) is stored in cylinders at the GDPs as a solid. The Company
accrues estimated costs for the future disposition of depleted UF(6), based upon
estimates for transportation, conversion and disposition. The accrued liability
amounted to $372.6 million at June 30, 1998. Pursuant to the USEC Privatization
Act, in July 1998, depleted UF(6) generated by the Company through the time of
the IPO was transferred to DOE. Depleted UF(6) generated after the IPO is the
responsibility of the Company.

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. The Company utilizes offsite treatment and disposal facilities
and stores wastes at the GDPs 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. All liabilities related to the disposal of stored
wastes generated prior to July 1, 1993, are the responsibility of DOE.

NUCLEAR INDEMNIFICATION

Pursuant to the Energy Policy Act and under the terms of the lease
agreement with DOE, the Company is indemnified by DOE under the Price-Anderson
Act for third-party liability claims arising from nuclear incidents with respect
to activities at the GDPs, including transportation of uranium to and from the
GDPs.

11. LEGAL PROCEEDINGS

In 1995, 15 of the Company's customers filed four substantially similar
lawsuits in the U.S. Court of Federal Claims challenging the Company's prices
under their Utility Services Contracts. Five of the 15 customers thereafter
negotiated new contracts with the Company and withdrew from the litigation. In
August 1996, the trial court granted the United States' motion for summary
judgment dismissing one of the suits; in July 1997, the Court of Appeals for the
Federal Circuit affirmed that decision. In December 1997, the trial court
granted the United States' motions to dismiss the remaining suits; the
plaintiffs did not seek to appeal those decisions.

12. COMMITMENTS AND CONTINGENCIES

POWER COMMITMENTS

Under the terms of the GDP lease, the Company purchases electric power at
amounts equivalent to actual cost incurred under DOE's power contracts with OVEC
and EEI that extend through December 2005. The Company has the right to have DOE
terminate the power contracts with notice ranging from three to five years and
is obligated to make minimum annual payments for demand charges, whether or not
it takes delivery of power, estimated as follows (in millions):

$505.5
======

Under the power contracts with DOE, in July 1993 the Company assumed
responsibility for DOE's guarantee of OVEC's senior secured notes with a
remaining balance of $62.0 million at June 30, 1998, 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. The minimum
demand charges under the OVEC contract include annual debt service of $10.5
million to fully amortize the notes by the scheduled maturity in December 2005.

Upon termination of the power contracts, the Company is responsible 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. Estimated costs are accrued and charged to production costs over the
contract period, and the accrued cost included in other liabilities amounted to
$18.1 million at June 30, 1998.

LEASE COMMITMENTS

Total costs incurred under the GDP lease with DOE and leases for office
space and equipment aggregated $18.7 million, $23.2 million, and $11.5 million
for the years ended June 30, 1996, 1997 and

NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

1998, respectively, and include costs relating to DOE's regulatory oversight of
the GDPs. In March 1997, the NRC assumed regulatory oversight. Minimum lease
payments for the GDP lease and leases for office space and equipment is
estimated at $5.0 million for each of the years ending June 30, 1999 to 2003.

The Company has the right to extend the GDP lease indefinitely at its sole
option, and the Company may terminate the lease in its entirety or with respect
to one of the GDPs at any time upon two years' notice. Upon termination of the
lease, the Company is responsible for certain lease turnover activities at the
GDPs, including documentation of the condition of the GDPs and termination of
facility operations. Lease turnover costs are accrued and charged to production
costs over the lease period, which is estimated to extend through 2005, and the
accrued cost included in other liabilities amounted to $24.5 million at
September 30, 1998.

13. FAIR VALUE OF FINANCIAL INSTRUMENTS AND CONCENTRATIONS OF CREDIT RISK

Financial instruments are reported on the balance sheets and include cash
and cash equivalents, accounts receivable and payable, certain accrued
liabilities, and payables under Russian HEU Contract, the carrying amounts for
which approximate fair value. In July 1998, the Company's financial instruments
include debt of $550.0 million borrowed at the time of the IPO.

At June 30, 1998, trade receivables from sales of SWU to electric utility
customers located in the United States, Asia and Europe amounted to $149.9
million, $62.7 million, and $5.9 million, respectively. The Company has provided
extended payment terms to an Asian customer with respect to an overdue trade
receivable of $36.0 million at June 30, 1998. Interest accrues on the unpaid
balance.

Credit risk could result from the possibility of a utility customer failing
to perform according to the terms of a long-term requirements contract.
Extension of credit is based on an evaluation of each customer's financial
condition. The Company 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.

=====          ========     =========     =========

The Energy Policy Act required that the Company issue capital stock to the
U.S. Government, held on its behalf by the Secretary of the U.S. Treasury. Since
assets and liabilities were transferred between agencies of the U.S. Government
(DOE and USEC) pursuant to a Determination Order, they were recorded at DOE's
historical cost.

In connection with the IPO, the par value of the common stock was changed
to $.10 per share, and 100 million shares are issued and outstanding.

Under the USEC Privatization Act, in April 1998, DOE transferred to the
Company 50 metric tons of HEU and 7,000 metric tons of natural uranium. The
Company is responsible for costs related to the blending of the HEU into LEU, 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.

Pursuant to the USEC Privatization Act, in December 1996, the Company
transferred to DOE the natural uranium component of low enriched uranium ("LEU")
from HEU purchased under the Russian HEU 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.

Pursuant to the USEC Privatization Act, at the time of the IPO on July 28,
1998, depleted uranium generated by the Company from July 1993 to July 1998 was
transferred to DOE, and the accrued liability of $373.8 million for depleted
uranium disposition was transferred to stockholders' equity.

15. EMPLOYEE BENEFIT PLANS

Effective January 1994, a non-contributory defined benefit pension plan was
established by the Company to provide retirement benefits to its employees based
on salary and years of service. Certain employees who transferred from other
government agencies elected to continue participation in the federal retirement
programs. Pension costs, including costs for the Company's 401(k) plan, amounted
to $1.0 million for each of the years ended June 30, 1996, 1997 and 1998. At
June 30, 1998, based on an assumed discount rate of 7.5%, an assumed
compensation rate of 5% and an assumed rate of return on plan assets of 8%, the
actuarial value of projected benefit obligations was $1.0 million, none of which
was vested, the fair value of plan assets was $1.1 million, and the amount of
unfunded accrued pension costs included in current liabilities was $.1 million.

16. OPERATIONS AND MAINTENANCE CONTRACT

Under an operations and maintenance contract with the Company (the "LMUS
Contract"), LMUS provides labor, services, and materials and supplies to operate
and maintain the GDPs, for which the Company funds LMUS for its actual costs and
pays contracted fees. The LMUS Contract expires October 2000 and may be
terminated by the Company without penalty at any time upon six-months' notice.
If LMUS meets certain specified operating and safety criteria and demonstrates
cost savings that exceed certain targets, LMUS can earn an annual incentive fee.

Under the operations and maintenance contract, USEC is responsible for and
accrues for its pro rata share of pension and other postretirement health and
life insurance costs relating to LMUS employee benefit plans. All costs related
to years of service prior to July 1, 1993, are the responsibility of DOE. The
Company's responsibility for funding its pro rata share of LMUS pension and
other postretirement benefit costs is determined based on actuarial estimates
and amounted to $21.8 million, $20.8 million, and $22.4 million for the years
ended June 30, 1996, 1997 and 1998, respectively.

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 GDP workers in connection with workforce reductions over
the next two years.

17. TRANSACTIONS WITH THE DEPARTMENT OF ENERGY

In June 1998, the Company paid $50.0 million to DOE, and DOE assumed
responsibility for disposal of a certain amount of depleted UF(6) generated by
the Company from its operations at the GDPs from October 1998 to 2005. The
prepaid asset will be amortized as a charge against production costs over the
life of the agreement.

Services are provided to DOE by the Company for environmental restoration,
waste management and other activities based on actual costs incurred at the
GDPs. Reimbursements by DOE to the Company for actual costs incurred amounted to
$68.5 million, $53.4 million, and $51.6 million for the years ended June 30,
1996, 1997 and 1998, respectively. Amounts receivable from DOE for actual costs
incurred for services amounted to $10.0 million and $17.9 million at June 30,
1997 and 1998, respectively.

Receivables from DOE of $104.8 million at June 30, 1997, relate to costs
associated with modifications to bring the GDPs into compliance with NRC
certification standards and nuclear safeguard requirements incurred by the
Company and reimbursable by DOE. The reimbursement was satisfied in May 1998 by
the transfer from DOE of 13 metric tons of HEU blended into the GDP production
stream, and transfers of natural uranium and LEU that were recorded in May 1998
at DOE's historical cost. The Company estimates its remaining cash outlays for
completion of such upgrades, included in current

F-17

USEC INC.

NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

liabilities at June 30, 1998, amount to $41.2 million, the reimbursement for
which was completed by the transfers of uranium and LEU in May 1998.

Receivables from DOE at June 30, 1997, include the balance of $19.6 million
representing amounts receivable from DOE relating to the Determination Order,
dated July 1, 1993, payment of which was satisfied by the transfers of uranium
and LEU in May 1998.

(1)  The Company's revenue and financial performance are substantially
influenced by the timing of customer nuclear reactor refuelings that are
affected by, among other things, the seasonal nature of electricity demand
and production. The timing of customer reactor fuel reloads, which
generally occur every 12 to 24 months, tends to be fairly predictable over
the long run, but may vary quarter-to-quarter and can affect financial
comparisons. Utilities typically schedule the shutdown of their reactors
for refueling during low demand periods of spring and fall to reduce costs
associated with reactor downtime. The Company 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.

(2)  Special charges amounted to $46.6 million for costs related to the
Privatization and certain severance and transition benefits to be paid to
GDP workers in connection with workforce reductions over the next two
years.

(3)  Project development costs primarily represent planned development and
engineering spending for the future commercialization of the AVLIS uranium
enrichment process.

(4)  The Company was exempt from federal, state and local income taxes until the
time of the IPO.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Company's By-Laws incorporate substantially the provisions of the
General Corporation Law of the State of Delaware (the "DGCL") in providing for
indemnification of directors and officers against expenses, judgments, fines,
settlements and other amounts actually and reasonably incurred in connection
with any proceeding arising by reason of the fact that such person is or was an
officer or director of the Company. In addition, the Company is authorized to
indemnify employees and agents of the Company and may enter into indemnification
agreements with its directors and officers providing mandatory indemnification
to them to the maximum extent permissible under Delaware law.

The Company's Certificate of Incorporation provides that the Company shall
indemnify (including indemnification for expenses incurred in defending or
otherwise participating in any proceeding) its directors and officers to the
fullest extent authorized or permitted by the DGCL, as it may be amended, and
that such right to indemnification shall continue as to a person who has ceased
to be a director or officer of the Company and shall inure to the benefit of his
or her heirs, executors and administrators except that such right shall not
apply to proceedings initiated by such indemnified person unless it is a
successful proceeding to enforce indemnification or such proceeding was
authorized or consented to by the Board of Directors. The Company's Certificate
of Incorporation also specifically provides for the elimination of the personal
liability of a director to the corporation and its stockholders for monetary
damages for breach of fiduciary duty as a director. The provision is limited to
monetary damages, applies only to a director's actions while acting within his
or her capacity as a director, and does not entitle the Company to limit
director liability for any judgment resulting from (a) any breach of the
director's duty of loyalty to the Company or its stockholders; (b) acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of the law; (c) paying an illegal dividend or approving an illegal
stock repurchase; or (d) any transaction from which the director derived an
improper benefit.

Section 145 of the DGCL provides generally that a person sued (other than
in a derivative suit) as a director, officer, employee or agent of a corporation
may be indemnified by the corporation for reasonable expenses, including counsel
fees, if the person acted in good faith and in a manner the person reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had no reasonable cause to
believe that the person's conduct was unlawful. In the case of a derivative
suit, a director, officer, employee or agent of the corporation may be
indemnified by the corporation for reasonable expenses, including attorneys'
fees, if the person has acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made in the case of a
derivative suit in respect of any claim as to which such director, officer,
employee or agent has been adjudged to be liable to the corporation unless the
Delaware Court of Chancery or the court in which such action or suit was brought
shall determine that such person is

II-1

93

fairly and reasonably entitled to indemnity for proper expenses. Indemnification
is mandatory under section 145 of the DGCL in the case of a director or officer
who is successful on the merits in defense of a suit against him.

The Purchase Agreement provides that the Underwriters are obligated, under
certain circumstances, to indemnify the Company, the directors, certain officers
and controlling persons of USEC Inc. against certain liabilities, including
liabilities under the Securities Act of 1933, as amended (the "Act"). Reference
is made to the form of Purchase Agreement filed as Exhibit 1.1, hereto.

The Company has entered into indemnification agreements with the directors
and certain officers pursuant to which the Company has agreed to maintain
directors' and officers' insurance and to indemnify such officers to the fullest
extent permitted by applicable law except for certain claims described therein.
Reference is made to the form of Director and Officer Indemnification Agreement
filed as Exhibit 10.24 hereto.

The Company maintains directors and officers liability insurance for the
benefit of its directors and certain of its officers.

ITEM 17.  UNDERTAKINGS.

Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the registrant
pursuant to provisions described in Item 14 above, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

The undersigned registrant hereby undertakes that:

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

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

The undersigned registrant hereby undertakes to provide to the underwriters
at the closing specified in the Purchase Agreement, certificates in such
denominations and registered in such names as required by the underwriters to
permit prompt delivery to each purchaser.

interest, and the interest component of rent expense.
