PART I

ITEM 1. BUSINESS.

GENERAL

Union Electric Company, headquartered in St. Louis, Missouri, is a
wholly-owned subsidiary of Ameren Corporation (Ameren) and operates as AmerenUE.
We operate a rate-regulated electric generation, transmission and distribution
business and a rate-regulated natural gas distribution business in Missouri and
Illinois. We were incorporated in Missouri in 1922 and are successor to a number
of companies, the oldest of which was organized in 1881. We are the largest
electric utility in the State of Missouri and supply electric and gas service in
parts of central and eastern Missouri and west central Illinois having an
estimated population of 2.6 million within an area of approximately 24,500
square miles, including the greater St. Louis area. In addition, our retail gas
utility service is supplied in 90 Missouri communities and in the City of Alton,
Illinois and vicinity. We supply electric service to about 1.2 million customers
and natural gas service to about 130,000 customers.

When we refer to AmerenUE, our, we or us, we are referring to Union
Electric Company and in some cases our agents, AmerenEnergy Inc. and
AmerenEnergy Fuels and Services Company.

Ameren was incorporated in Missouri on August 7, 1995 and is a public
utility holding company registered with the Securities and Exchange Commission
(SEC) under the Public Utility Holding Company Act of 1935 (PUHCA). Ameren is
headquartered in St. Louis, Missouri. On December 31, 1997, following the
receipt of all required approvals, we and CIPSCO Incorporated (CIPSCO) combined
with the result that our common shareholders and the common shareholders of
CIPSCO became the common shareholders of Ameren, and Ameren became the owner of
100% of our common stock and the common stock of CIPSCO's operating
subsidiaries: Central Illinois Public Service Company and CIPSCO Investment
Company. Ameren completed its acquisition of CILCORP Inc. (CILCORP) on January
31, 2003 and of AES Medina Valley Cogen (No. 4), LLC on February 4, 2003 from
The AES Corporation (AES). See CILCORP Acquisition below for further
information. In addition to us, Ameren's primary subsidiaries and our affiliates
are as follows:

o Central Illinois Public Service Company, which operates a rate-regulated
electric and natural gas transmission and distribution business in Illinois
as AmerenCIPS. AmerenCIPS was incorporated in Illinois in 1902. It supplies
electric and gas utility service to portions of central and southern
Illinois having an estimated population of 820,000 within an area of
approximately 20,000 square miles. AmerenCIPS supplies electric service to
about 325,000 customers and natural gas service to about 170,000 customers.
o Central Illinois Light Company, a subsidiary of CILCORP, which operates a
rate-regulated transmission and distribution business, an electric
generation business, and a rate-regulated natural gas distribution business
in Illinois as AmerenCILCO. AmerenCILCO was incorporated in Illinois in
1913. It supplies electric and gas utility service to territories in
central and east central Illinois in an area of approximately 3,700 and
4,500 square miles, respectively. AmerenCILCO supplies electric service to
about 200,000 customers and natural gas service to about 205,000 customers.
See CILCORP Acquisition below for further information.
o AmerenEnergy Resources Company (Resources Company), which consists of non
rate-regulated operations. Subsidiaries include AmerenEnergy Generating
Company (Generating Company) that operates non rate-regulated electric
generation in Missouri and Illinois, AmerenEnergy Marketing Company
(Marketing Company), which markets power for periods over one year,
AmerenEnergy Fuels and Services Company, which procures fuel and manages
the related risks for our affiliated companies and AmerenEnergy Medina
Valley Cogen (No. 4), LLC, which indirectly owns a 40 megawatt, gas-fired
electric co-generation plant. On February 4, 2003, Ameren completed its
acquisition of AES Medina Valley Cogen (No. 4), LLC from AES and renamed it
AmerenEnergy Medina Valley Cogen (No. 4), LLC. See CILCORP Acquisition
below for further information. Generating Company was incorporated in
Illinois in March 2000 in conjunction with the Illinois Electric Service
Customer Choice and Rate Relief Law of 1997 (the Illinois Law). This
Illinois Law provides for electric utility restructuring and introduces
competition into the retail supply of electric energy in Illinois.
Generating Company commenced operations on May 1, 2000 when AmerenCIPS
transferred to Generating Company all of the following: its generating
assets, consisting of the generating facilities described below under Item
2. Properties; all related fuel, supply, transportation, maintenance and
labor agreements; approximately 45% of AmerenCIPS' employees; and some
other related rights, assets and liabilities.
o Ameren Services Company (Ameren Services), incorporated in Missouri, which
provides administrative, accounting, legal, engineering, executive and
other support services to Ameren and all of its subsidiaries;
o AmerenEnergy, Inc., which serves as a power marketing and risk management
agent for us and Generating Company for transactions of primarily less than
one year;

1



o Electric Energy, Inc. (EEI), which operates electric generation and
transmission facilities in Illinois that supply electric power primarily to
a uranium enrichment plant located in Paducah, Kentucky. We have a 40%
ownership interest in EEI and have accounted for it under the equity method
of accounting. Resources Company also owns a 20% interest in EEI. On April
30, 2002, AmerenCIPS transferred its 20% common stock interest in EEI to
Ameren in the form of a non-cash dividend of common stock in EEI.
Subsequently, Ameren contributed such stock to Resources Company. The
transfer completed the process of achieving a full divestiture of all
electric generating capacity that had been owned directly or indirectly by
AmerenCIPS. The remaining 40% of the common stock of EEI is held 20% each
by Kentucky Utilities Company and Illinova Generating Company.

For additional information regarding the acquisition of CILCORP and AES
Medina Valley Cogen (No. 4) LLC, see Recent Developments in Management's
Discussion and Analysis of Financial Condition and Results of Operations under
Item 7 and Notes 1 and 17 to our Financial Statements under Item 8.

For the year 2002, 95% (2001 - 95%; 2000 - 95%) of our total operating
revenues were derived from the sale of electric energy and 5% (2001 - 5%; 2000 -
5%) from the sale of natural gas.

We employed 4,304 persons at December 31, 2002. For information on a
voluntary retirement program offered in December 2002 and on labor agreements
and other labor matters, see Outlook - Labor Agreements in Management's
Discussion and Analysis of Financial Condition and Results of Operations under
Item 7 and Notes 10 and 14, respectively, to our Financial Statements under Item
8.

CILCORP Acquisition

On January 31, 2003, after receipt of the necessary regulatory agency
approvals and clearance from the Department of Justice under the
Hart-Scott-Rodino Antitrust Improvements Act, Ameren completed its acquisition
of all of the outstanding common stock of CILCORP from AES. CILCORP is the
parent company of Peoria, Illinois-based Central Illinois Light Company, which
operated as CILCO. With the acquisition, CILCO became an Ameren subsidiary, but
remains a separate utility company, operating as AmerenCILCO. On February 4,
2003, Ameren also completed its acquisition of AES Medina Valley Cogen (No. 4),
LLC (Medina Valley), which indirectly owns a 40 megawatt, gas-fired electric
co-generation plant. With the acquisition, Medina Valley became a wholly-owned
subsidiary of Resources Company and was renamed AmerenEnergy Medina Valley Cogen
(No. 4), LLC. The CILCORP and AmerenEnergy Medina Valley Cogen (No. 4), LLC
financial statements will be included in Ameren's consolidated financial
statements effective with the January and February 2003 acquisition dates.

Ameren acquired CILCORP to complement its existing Illinois electric and
gas operations. The purchase included CILCO's rate-regulated electric and
natural gas businesses in Illinois serving approximately 200,000 and 205,000
customers, respectively, of which approximately 150,000 are combination electric
and gas customers. CILCO's service territory is contiguous to Ameren's service
territory. CILCO also has a non rate-regulated electric and gas marketing
business principally focused in the Chicago, Illinois region. Finally, the
purchase includes approximately 1,200 megawatts of largely coal-fired generating
capacity, most of which is expected to become non rate-regulated in 2003.

The total purchase price was approximately $1.4 billion and included the
assumption of CILCORP and Medina Valley debt and preferred stock at closing of
approximately $900 million, with the balance of the purchase price of
approximately $500 million paid with cash on hand. The purchase price is subject
to certain adjustments for working capital and other changes pending the
finalization of CILCORP's closing balance sheet. The cash component of the
purchase price came from Ameren's issuances in September 2002 of 8.05 million
common shares and in early 2003 of 6.325 million common shares.

For additional information regarding our business operations, see
Management's Discussion and Analysis of Financial Condition and Results of
Operations under Item 7 and Note 1 to our Financial Statements under Item 8.


CAPITAL PROGRAM AND FINANCING

For information on our capital program and financial needs, see Liquidity
and Capital Resources in Management's Discussion and Analysis of Financial
Condition and Results of Operations under Item 7 and Notes 6, 7, 8, 9 and 14 to
our Financial Statements under Item 8.

RATES AND REGULATION

Rates

Rates that we are allowed to charge for our services are the single most
important item influencing our financial position, results of operations and
liquidity. We are highly regulated. The rates we charge our customers are
determined by governmental organizations. Decisions by these organizations are
influenced by many factors, including our recent cost of providing service, our
quality of service, regulatory staff knowledge and experience, economic
conditions and social and political views. Decisions made by these organizations
regarding our rates could have a material impact on our financial position,
results of operations and liquidity.

For the year 2002, approximately 86% of our electric operating revenues
were based on rates regulated by the Missouri Public Service Commission (MoPSC),
6% by the Illinois Commerce Commission (ICC), and 8% by the Federal Energy
Regulatory Commission (FERC). For information on rate matters in these
jurisdictions, including our recent Missouri electric rate case, see Results of
Operations and Regulatory Matters in Management's Discussion and Analysis of
Financial Condition and Results of Operations under Item 7 and Note 2 to our
Financial Statements under Item 8.

General Regulatory Matters

As a subsidiary of Ameren, a holding company registered with the SEC under
the PUHCA, we are subject to the regulatory provisions of the PUHCA, including
provisions relating to the issuance of securities, sales and acquisitions of
securities and utility assets, affiliate transactions, financial reporting
requirements, and the services performed by Ameren Services and AmerenEnergy
Fuels and Services Company. Issuance of short-term and long-term debt and other
securities by Ameren and issuance of debt having a maturity of twelve months or
less by AmerenCIPS, AmerenUE and AmerenCILCO are subject to approval by the SEC
under the PUHCA.

We are subject to regulation, as applicable, by the ICC and the MoPSC as to
rates, service, issuance of equity securities, issuance of debt having a
maturity of more than twelve months, mergers, and various other matters.

We are also subject to regulation by the FERC as to rates and charges in
connection with the wholesale sale of energy and transmission in interstate
commerce, mergers, affiliate transactions, and certain other matters

Operation of our Callaway nuclear plant is subject to regulation by the
Nuclear Regulatory Commission. Our Facility Operating License for our Callaway
plant expires on October 18, 2024. Our Osage hydroelectric plant and Taum Sauk
pumped-storage hydro plant, as licensed projects under the Federal Power Act,
are subject to FERC regulations affecting, among other things, the general
operation and maintenance of the projects. The license for the Osage Plant
expires on February 28, 2006, and the license for the Taum Sauk Plant expires on
June 30, 2010. We are currently seeking renewal of our Osage Plant license. Our
Keokuk Plant and dam located in the Mississippi River between Hamilton, Illinois
and Keokuk, Iowa, are operated under authority, unlimited in time, granted by an
Act of Congress in 1905.

For information on regulatory matters in these jurisdictions, including the
current status of electric transmission matters pending before the FERC, see
Regulatory Matters in Management's Discussion and Analysis of Financial
Condition and Results of Operations under Item 7 and Note 2 to our Financial
Statements under Item 8.

Environmental Matters

Certain of our operations are subject to federal, state and local
environmental regulations relating to the safety and health of personnel, the
public and the environment, including the identification, generation, storage,
handling, transportation, disposal, record keeping, labeling, reporting of and
emergency response in connection with hazardous and toxic materials, safety and
health standards, and environmental protection requirements, including standards
and limitations relating to the discharge of air and water pollutants. Failure
to comply with those statutes or regulations could have material adverse effects
on us, including the imposition of criminal or civil liability by regulatory
agencies or civil fines and liability to private parties, and the required
expenditure of funds to bring us into compliance. We believe we are in material
compliance with existing regulations.

For additional discussion of environmental matters, see Liquidity and
Capital Resources in Management's Discussion and Analysis of Financial Condition
and Results of Operations under Item 7 and Note 14 to our Financial Statements
under Item 8.

FUEL SUPPLY FOR ELECTRIC GENERATING FACILITIES

Cost of Fuels Year
------------------------------------------------------------------------------
(Per Million BTU) 2002 2001 2000 1999 1998
---- ---- ---- ---- ----

Coal 91.352(cent) 98.228(cent) 96.004(cent) 100.685(cent) 100.015(cent)
Nuclear 38.051(cent) 37.184(cent) 40.269(cent) 46.552(cent) 48.803(cent)
Natural Gas (a) 340.689(cent) 402.546(cent) 429.354(cent) 243.315(cent) 226.572(cent)
Average - all fuels (b) 81.325(cent) 86.696(cent) 84.213(cent) 89.833(cent) 90.378(cent)


(a) The fuel cost for natural gas represents the actual cost of
natural gas and variable costs for transportation, storage, balancing
and fuel losses for delivery to the plant. In addition, the fixed
costs for firm transportation and firm storage capacity are included
to calculate a "fully-loaded" fuel cost for the generating facilities.
(b) Represents all fuels utilized in our electric generating
facilities, including coal, nuclear, natural gas, oil, propane, tire
chips, and handling.

Coal

We have a policy of maintaining coal inventory consistent with our
historical usage. We may adjust levels based on uncertainties of supply due
to potential work stoppages, delays in coal deliveries, equipment
breakdowns and other factors. As of December 31, 2002, approximately 63
days supply (2001 - 55 days supply) of coal was in inventory. For the year
ended December 31, 2002, coal represented approximately 77% of our fuel
supply.

Nuclear

The components of the nuclear fuel cycle required for nuclear generating
units are as follows:

o uranium;
o conversion of uranium into uranium hexafluoride;
o enrichment of uranium hexafluoride;
o conversion of enriched uranium hexafluoride into uranium dioxide and
the fabrication into nuclear fuel assemblies; and
o disposal and/or reprocessing of spent nuclear fuel.

We have agreements and/or inventories to fulfill our Callaway nuclear plant
needs for uranium, conversion, enrichment and fabrication services. Such needs
are satisfied through 2004, with the exception of enrichment services. A supply
of enrichment services for unfulfilled needs after 2004 is being pursued.
Additional contracts will be entered into in order to supply nuclear fuel during
the remainder of the life of the plant, at prices which cannot now be accurately
predicted. Our Callaway plant normally requires refueling at 18-month intervals,
and the next refueling is scheduled for the spring of 2004. Our Callaway plant
is out of service for approximately one month during a refueling.

For the year ended December 31, 2002 nuclear represented approximately 20%
of our fuel supply. See Note 15 to our Financial Statements under Item 8 for
additional information.

Natural Gas

The combustion turbine generator equipment (CTs), which we placed into
commercial operation in 2002 and 2000, are fueled by natural gas or have the
capability to use natural gas or oil. We use natural gas to supply our
generating facilities during peak generating periods. Our natural gas
procurement strategy is designed to ensure reliable and immediate delivery of
natural gas by optimizing transportation, storage, and balancing options and
minimizing cost and price risk by structuring various supply agreements to
maintain access to multiple gas pools and supply basins and reducing the impact
of price volatility. For additional information on CTs and related fuel matters,
see Liquidity and Capital Resources and Quantitative and Qualitative Disclosures
About Market Risk in Management's Discussion and Analysis of Financial Condition
and Results of Operations under Item 7 and Note 14 to our Financial Statements
under Item 8.

4



Oil

The actual and prospective use of oil is minimal, and we have not
experienced and do not expect to experience difficulty in obtaining adequate
supplies. For the year ended December 31, 2002, oil represented approximately 3%
of our fuel supply.

For additional information on our fuel supply, see Results of Operations,
Liquidity and Capital Resources, Effects of Inflation and Changing Prices and
Quantitative and Qualitative Disclosures About Market Risk in Management's
Discussion and Analysis of Financial Condition and Results of Operations under
Item 7 and Notes 1, 4, 14 and 15 to our Financial Statements under Item 8.


INDUSTRY ISSUES

We are facing issues common to the electric and gas utility industries.
These issues include:

o the potential for more intense competition;
o the potential for changes in the structure of regulation;
o changes in the structure of the industry as a result of changes in
federal and state laws, including the formation of unregulated
generating entities and regional transmission organizations;
o weak power prices due to overbuilt capacity and a weak economy;
o numerous troubled companies within the energy sector and their
impact on energy marketing and access to the capital markets;
o on-going consideration of additional changes of the industry by
federal and state authorities;
o continually developing environmental laws, regulations and issues,
including proposed new air quality standards;
o public concern about the siting of new facilities;
o proposals for demand-side management programs;
o public concerns about nuclear decommissioning and the disposal of
nuclear wastes; and
o global climate issues.

We are monitoring these issues and are unable to predict at this time what
impact, if any, these issues will have on our operations, financial condition or
liquidity. For additional information, see Outlook and Regulatory Matters in
Management's Discussion and Analysis of Financial Condition and Results of
Operations under Item 7 and Notes 2 and 14 to our Financial Statements under
Item 8.

ITEM 2. PROPERTIES.

For information on our principal properties, planned additions or
replacements and transfers, see the generating facilities table below and
Liquidity and Capital Resources and Regulatory Matters in Management's
Discussion and Analysis of Financial Condition and Results of Operations under
Item 7 and Notes 2 and 14 to our Financial Statements under Item 8. Future plans
regarding additional electric generating facilities referred to in this report
are subject to change, including increasing or decreasing planned or installed
future generating capacity, based on market conditions, regulatory approvals for
additions, our results of operations and financial condition, availability of
financing and other factors determined by management.

We are a member of MAIN (Mid-America Interconnected Network), which is one
of the ten regional electric reliability councils organized for coordinating the
planning and operation of the nation's bulk power supply. MAIN operates
primarily in Wisconsin, Michigan, Illinois and Missouri.

Ameren's bulk power system is operated as an Ameren-wide control area and
transmission system under the FERC-approved amended joint dispatch agreement
between AmerenUE and our affiliates, Generating Company and AmerenCIPS. The
amended joint dispatch agreement provides a basis upon which we and Generating
Company can participate in the coordinated operation of AmerenCIPS's and our
transmission facilities with Generating Company's and our generating facilities
in order to achieve economies consistent with the provision of reliable electric
service and an equitable sharing of the benefits and costs of that coordinated
operation. Ameren, in 2002, had more than 30 interconnections for transmission
service and the exchange of electric energy, directly and through the facilities
of others. Our other Illinois-based affiliate, AmerenCILCO, is currently
expected to continue to operate as a separate control area. As such, its
generating plants will not be jointly dispatched with the generating plants
owned by Generating Company and us. AmerenCILCO is a transmission owning member
of the Midwest Independent System Operating (Midwest ISO) and has transferred
functional control of its system to the Midwest ISO. Transmission service on the
AmerenCILCO transmission system is provided pursuant to the terms of the Midwest
ISO open access transmission tariff on file with the FERC. For information on
AmerenCIPS' and AmerenUE's participation in the Midwest ISO, see Note 2 to our
Financial Statements under Item 8.

The following table sets forth information with respect to our generating
facilities and capability at the time of our expected 2003 peak summer

through 8 and Kinmundy CTs 1 and 2) is proposed to be transferred from
Generating Company to AmerenUE subject to receipt of necessary
regulatory approvals.
(f) "Net Heat Rate" represents the amount of energy to produce a given
unit of output and is expressed as BTU per kilowatthour.
(g) We own a 40% interest in EEI.


As of December 31, 2002, we owned approximately 3,200 circuit miles of
electric transmission lines. We operate three propane-air plants and 2,900 miles
of gas mains. Our other properties include distribution lines, underground
cable, office buildings, warehouses, garages and repair shops.

We have fee title to all principal plants and other important units of
property, or to the real property on which such facilities are located (subject
to a mortgage lien securing our outstanding first mortgage bond indebtedness and
to permitted liens and judgment liens, as defined), except that:

o a portion of the Osage Plant reservoir, certain facilities at the
Sioux Plant, most of our Peno Creek combustion turbine generating
facility, certain of our substations and most of our transmission and
distribution lines and gas mains are situated on lands occupied under
leases, easements, franchises, licenses or permits;
o the United States and/or the State of Missouri own, or have or may
have, paramount rights to certain lands lying in the bed of the Osage
River or located between the inner and outer harbor lines of the
Mississippi River, on which certain of our generating and other
properties are located; and

7



o the United States and/or State of Illinois and/or State of Iowa and/or
City of Keokuk, Iowa own, or have or may have, paramount rights with
respect to, certain lands lying in the bed of the Mississippi River on
which a portion of our Keokuk Plant is located.

Substantially all of our property and plant are subject to the direct first
lien of the indenture securing our first mortgage bonds.

In December 2002, for the purpose of achieving property tax savings, we
conveyed most of our Peno Creek combustion turbine generating facility to the
City of Bowling Green, Missouri, and leased back the facility from the City for
a 20 year term. As part of the transaction, most of our Peno Creek property and
plant was released from the lien of the indenture securing our first mortgage
bonds. Under the terms of the lease, we retain all operation and maintenance
responsibilities for the facility and ownership of the facility is returned to
us at the expiration of the lease. When ownership of the Peno Creek facility is
returned to us by the City, the property and plant will again become encumbered
by the direct first lien of our outstanding first mortgage bond indenture.


ITEM 3. LEGAL PROCEEDINGS.

We are involved in legal and administrative proceedings before various
courts and agencies with respect to matters arising in the ordinary course of
business, some of which involve substantial amounts. We believe that the final
disposition of these proceedings, except as otherwise noted in this report, will
not have a material adverse effect on our financial position, results of
operations or liquidity.

For additional information on legal and administrative proceedings, see
Rates and Regulation under Item 1 and Liquidity and Capital Resources and
Regulatory Matters in Management's Discussion and Analysis of Financial
Condition and Results of Operations under Item 7 and Notes 2 and 14 to our
Financial Statements under Item 8.


FORWARD-LOOKING STATEMENTS

Statements made in this report which are not based on historical facts, are
"forward-looking" and, accordingly, involve risks and uncertainties that could
cause actual results to differ materially from those discussed. Although such
"forward-looking" statements have been made in good faith and are based on
reasonable assumptions, there is no assurance that the expected results will be
achieved. These statements include (without limitation) statements as to future
expectations, beliefs, plans, strategies, objectives, events, conditions and
financial performance. In connection with the "safe harbor" provisions of the
Private Securities Litigation Reform Act of 1995, we are providing this
cautionary statement to identify some important factors that could cause actual
results to differ materially from those anticipated. The following factors, in
addition to those discussed elsewhere in this report and in subsequent
securities filings, could cause results to differ materially from management
expectations as suggested by such "forward-looking" statements:

o the effects of the stipulation and agreement relating to our Missouri
electric excess earnings complaint case and other regulatory actions,
including changes in regulatory policy;
o changes in laws and other governmental actions, including monetary and
fiscal policies;
o the impact on us of current regulations related to the opportunity for
customers to choose alternative energy suppliers in Illinois;
o the effects of increased competition in the future due to, among other
things, deregulation of certain aspects of our business at both the state
and federal levels;
o the effects of participation in a FERC-approved Regional Transmission
Organization, including activities associated with the Midwest ISO;
o availability and future market prices for fuel and purchased power,
electricity and natural gas, including the use of financial and derivative
instruments and volatility of changes in market prices;
o the cost of commodities, such as natural gas, used in the production of
electricity and our ability to
recover such increased cost;
o average rates for electricity in the Midwest;
o business and economic conditions;
o the impact of the adoption of new accounting standards on the application
of appropriate technical accounting rules and guidance;
o interest rates and the availability of capital;

8


o actions of rating agencies and the effects of such actions;
o weather conditions;
o generation plant construction, installation and performance;
o operation of nuclear power facilities and decommissioning costs;
o the effects of strategic initiatives, including acquisitions and
divestitures;
o the impact of current environmental regulations on utilities and generating
companies and the expectation that more stringent requirements will be
introduced over time, which could potentially have a negative financial
effect;
o future wages and employee benefit costs, including changes in returns of
benefit plan assets;
o disruptions of the capital markets or other events making Ameren's or our
access to necessary capital more difficult or costly;
o competition from other generating facilities, including new facilities that
may be developed in the future;
o cost and availability of transmission capacity for the energy generated by
our generating facilities or required to satisfy our energy sales; and
o legal and administrative proceedings.

Given these uncertainties, undue reliance should not be placed on these
forward-looking statements. Except to the extent required by the federal
securities laws, we undertake no obligation to publicly update or revise any
forward-looking statements, whether as a result of new information, future
events or otherwise.

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

OVERVIEW

Union Electric Company, headquartered in St. Louis, Missouri, is a
wholly-owned subsidiary of Ameren Corporation (Ameren) and operates as AmerenUE.
Our principal business is the rate-regulated generation, transmission and
distribution of electricity, and the rate-regulated distribution of natural gas
to residential, commercial, industrial and wholesale users in Missouri and
Illinois. Ameren is a public utility holding company registered with the
Securities and Exchange Commission (SEC) under the Public Utility Holding
Company Act of 1935 (PUHCA) and is also headquartered in St. Louis, Missouri.
Ameren's principal business is the generation, transmission and distribution of
electricity, and the distribution of natural gas to residential, commercial,
industrial and wholesale users in the central United States. In addition to us,
Ameren's principal subsidiaries and our affiliates are as follows:

o Central Illinois Public Service Company, which operates a rate-regulated
electric and natural gas transmission and distribution business in Illinois
as AmerenCIPS.
o Central Illinois Light Company is a subsidiary of CILCORP Inc. (CILCORP),
which operates a rate-regulated transmission and distribution business, an
electric generation business, and a rate-regulated natural gas distribution
business in Illinois as AmerenCILCO. Ameren completed its acquisition of
CILCORP on January 31, 2003 from The AES Corporation (AES). See Recent
Developments for further information.
o AmerenEnergy Resources Company (Resources Company), which consists of non
rate-regulated operations. Subsidiaries include AmerenEnergy Generating
Company (Generating Company) that operates non rate-regulated electric
generation in Missouri and Illinois, AmerenEnergy Marketing Company
(Marketing Company), which markets power for periods over one year,
AmerenEnergy Fuels and Services Company, which procures fuel and manages
the related risks for Ameren affiliated companies and AmerenEnergy Medina
Valley Cogen (No. 4), LLC, which indirectly owns a 40 megawatt, gas-fired
electric co-generation plant. On February 4, 2003, Ameren completed its
acquisition of AES Medina Valley Cogen (No. 4), LLC (Medina Valley) from
AES and renamed it AmerenEnergy Medina Valley Cogen (No. 4), LLC. See
Recent Developments for further information.
o AmerenEnergy, Inc. (AmerenEnergy), which serves as a power marketing and
risk management agent for Ameren affiliated companies for transactions of
primarily less than one year.
o Electric Energy, Inc. (EEI), which operates electric generation and
transmission facilities in Illinois. We have a 40% ownership interest in
EEI and have accounted for it under the equity method of accounting.
Resources Company also owns a 20% interest in EEI.
o Ameren Services Company (Ameren Services), which provides shared support
services to Ameren and its subsidiaries, including us. Charges are based
upon the actual costs incurred by Ameren Services, as required by the
PUHCA.

When we refer to AmerenUE, our, we or us, we are referring to Union
Electric Company and in some cases our agents, AmerenEnergy and AmerenEnergy
Fuels and Services Company. All tabular dollar amounts are in millions, unless
otherwise indicated.

Our results of operations and financial position are impacted by many
factors, including both controllable and uncontrollable factors. Weather,
economic conditions and the actions of key customers or competitors can
significantly impact the demand for our services. Our results are also impacted
by seasonal fluctuations caused by winter heating and summer cooling demand.
With nearly all of our revenues directly subject to regulation by various state
and federal agencies, decisions by regulators can have a material impact on the
price we charge for our services. We principally utilize coal, nuclear fuel,
natural gas and oil in our operations. The prices for these commodities can
fluctuate significantly due to the world economic and political environment,
weather, production levels and many other factors. We do not have fuel recovery
mechanisms in Missouri or Illinois for our electric utility businesses, but we
do have gas cost recovery mechanisms in each state for our gas utility
businesses. In addition, our electric rates in Missouri and Illinois are largely
set through 2006. We employ various risk management strategies in order to try
to reduce our exposure to commodity risks and other risks inherent in our
business. The reliability of our power plants, and transmission and distribution
systems, and the level of operating and administrative costs, and capital
investment are key factors that we seek to control in order to optimize our
results of operations, cash flows and financial position.

RESULTS OF OPERATIONS

Earnings Summary

Our net income for 2002, 2001 and 2000 was $344 million, $374 million and
$353 million, respectively. Net income in 2002 included voluntary retirement and
other restructuring charges ($41 million, net of taxes), which consisted of a
voluntary retirement program and the retirement of our Venice, Illinois plant.
In 2001, net income was reduced by the adoption of Statement of Financial
Accounting Standards (SFAS) No. 133, "Accounting for Derivative Instruments and
Hedging Activities" ($5 million). See Other Operating Expenses - Restructuring
Charges below and Note 1 - Summary of Significant Accounting Policies to our
Financial Statements for further information.

The following table reconciles our net income to net income excluding
voluntary retirement and other restructuring charges and SFAS 133 adoption for
the years ending December 31, 2002, 2001 and 2000:

- --------------------------------------------------------------------------------
2002 2001 2000
- --------------------------------------------------------------------------------
Net income $344 $374 $353
- --------------------------------------------------------------------------------
Voluntary retirement and other restructuring
charges, net of taxes 41 - -
SFAS 133 adoption, net of taxes - 5 -
- --------------------------------------------------------------------------------
Net income excluding restructuring charges and
SFAS 133 adoption $ 385 $ 379 $ 353
- --------------------------------------------------------------------------------


Excluding the charges discussed above, our net income in 2002 increased $6
million from the prior year, primarily due to favorable weather conditions ($27
million, net of taxes) and lower fuel and purchased power costs ($44 million,
net of taxes). These increases were partially offset by the impact of the
settlement of our Missouri electric rate case ($37 million, net of taxes),
increased costs of employee benefits ($15 million, net of taxes) and other
operations and maintenance expenses ($8 million, net of taxes), higher
depreciation ($10 million, net of taxes, excluding the effect of the Missouri
electric rate case settlement) and a decline in industrial sales due to the
continued soft economy.

Excluding the charges discussed above, our net income in 2001 increased $26
million from 2000, primarily due to a reduction in estimated credits to Missouri
electric customers ($47 million, net of taxes), lower interest expense ($8
million, net of taxes) and organic growth. These increases were partially offset
by increased costs of employee benefits ($12 million, net of taxes), higher
depreciation ($6 million, net of taxes) and a refueling outage at our Callaway
nuclear plant. There was not a refueling at Callaway in 2000.

Recent Developments

CILCORP Acquisition

On January 31, 2003, after receipt of the necessary regulatory agency
approvals and clearance from the Department of Justice under the
Hart-Scott-Rodino Antitrust Improvements Act, Ameren completed its acquisition
of all of the outstanding common stock of CILCORP from AES. CILCORP is the
parent company of Peoria, Illinois-based Central Illinois Light Company, which
operated as CILCO. With the acquisition, CILCO became an Ameren subsidiary, but
remains a separate utility company, operating as AmerenCILCO. On February 4,
2003, Ameren also completed its acquisition of AES Medina Valley Cogen (No. 4),
LLC, which indirectly owns a 40 megawatt, gas-fired electric co-generation
plant. With the acquisition, Medina Valley became a wholly-owned subsidiary of
Resources Company and was renamed AmerenEnergy Medina Valley Cogen (No. 4), LLC.
The CILCORP and AmerenEnergy Medina Valley Cogen (No. 4), LLC financial
statements will be included in Ameren's consolidated financial statements
effective with the January and February 2003 acquisition dates.

Ameren acquired CILCORP to complement its existing Illinois electric and
gas operations. The purchase included CILCO's rate-regulated electric and
natural gas businesses in Illinois serving approximately 200,000 and 205,000
customers, respectively, of which approximately 150,000 are combination electric
and gas customers. CILCO's service territory is contiguous to Ameren's service
territory. CILCO also has a non rate-regulated electric and gas marketing
business principally focused in the Chicago, Illinois region. Finally, the
purchase includes approximately 1,200 megawatts of largely coal-fired generating
capacity, most of which is expected to become non rate-regulated in 2003.

The total purchase price was approximately $1.4 billion and included the
assumption of CILCORP and Medina Valley debt and preferred stock at closing of
approximately $900 million, with the balance of the purchase price of

14


approximately $500 million paid with cash on hand. The purchase price is subject
to certain adjustments for working capital and other changes pending the
finalization of CILCORP's closing balance sheet. The cash component of the
purchase price came from Ameren's issuances in September 2002 of 8.05 million
common shares and in early 2003 of 6.325 million common shares.

Credit Ratings

In April 2002, as a result of our then pending Missouri electric earnings
complaint case and the CILCORP transaction and related assumption of debt,
credit rating agencies placed Ameren's and its subsidiaries' debt under review.
Following the completion of the acquisition of CILCORP in January 2003, Standard
& Poor's lowered the ratings of Ameren, AmerenUE and AmerenCIPS and increased
the ratings of Generating Company. At the same time, Standard & Poor's changed
the outlook assigned to all of Ameren's and its subsidiaries' ratings to stable.
Moody's also lowered Ameren's and AmerenUE's ratings subsequent to the
acquisition and changed the outlook on these ratings to stable. These actions
were consistent with the actions the rating agencies disclosed they were
considering following the announcement of the CILCORP acquisition.

As of February 2003, the ratings by Moody's and Standard & Poor's were as
follows:

- --------------------------------------------------------------------------------
Moody's Standard & Poor's
- --------------------------------------------------------------------------------
Ameren Corporation:
Issuer/Corporate credit rating A3 A-
Unsecured debt A3 BBB+
Commercial paper P-2 A-2

AmerenUE:
Secured debt A1 A-
Unsecured debt A2 BBB+
Commercial paper P-1 A-2

AmerenCIPS:
Secured debt A1 A-
Unsecured debt A2 BBB+

Generating Company:
Unsecured debt A3/Baa2 A-
- --------------------------------------------------------------------------------

Standard & Poor's increased the ratings of CILCORP and CILCO subsequent to
the acquisition of these entities by Ameren. As of February 2003, the unsecured
debt ratings of CILCORP were BBB+ and Baa2 from Standard & Poor's and Moody's,
respectively. The secured debt ratings of AmerenCILCO were A- and A2 from
Standard & Poor's and Moody's, respectively. Standard & Poor's assigned stable
outlooks to the ratings. Moody's also assigned a stable outlook to the ratings
for CILCORP and AmerenCILCO.

Any adverse change in our ratings or Ameren's ratings may reduce our access
to capital and/or increase the costs of borrowings resulting in a negative
impact on earnings. A credit rating is not a recommendation to buy, sell or hold
securities and should be evaluated independently of any other rating. Ratings
are subject to revision or withdrawal at any time by the assigning rating
organization.

Electric Operations

The following table represents the favorable (unfavorable) impact on
electric margin versus the prior periods for the years ended December 31, 2002
and 2001:

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

Operating Revenues:
Effect of abnormal weather (estimate) $ 62 $ 4
Growth and other (estimate) (7) 31
2002 Missouri rate settlement (47) -

Generation efficiencies and other - 6
Purchased power 177 (15)
- --------------------------------------------------------------------------------
Total variation in fuel and purchased power 189 (10)
- --------------------------------------------------------------------------------
Change in electric margin $ 70 $ 40
- --------------------------------------------------------------------------------

Electric margin increased $70 million for the year ended December 31, 2002
compared to 2001. Increases in electric margin in 2002 were primarily
attributable to more favorable weather conditions and lower fuel and purchased
power costs. Weather-sensitive residential electric kilowatthour sales in 2002
increased 7% and commercial electric kilowatthour sales increased 4%. However,
industrial kilowatthour sales were approximately 9% lower in 2002 as compared to
2001 due primarily to the impact of the soft economy. Revenues were also reduced
by $47 million in 2002 due to the settlement of the Missouri electric rate case.
Interchange revenues decreased due to lower energy prices and less low-cost
generation available for sale, resulting primarily from increased demand for
generation from native load customers. Fuel and purchased power was reduced in
2002 due primarily to lower energy prices, partially offset by increased
kilowatthour sales and unscheduled plant outages. We expect that revenues will
continue to be negatively affected by the settlement of our Missouri rate case
reached in 2002, which requires the phase-in of $30 million of electric rate
reductions effective April 1, 2003 and $30 million effective April 1, 2004. In
addition, we expect power prices in the energy markets to remain generally soft,
which will impact the margins we can generate by marketing our power into the
interchange markets.

During 2002, we adopted the provisions of Emerging Issues Task Force (EITF)
Issue No. 02-3,"Issues Involved in Accounting for Derivative Contracts Held for
Trading Purposes and Contracts Involved in Energy Trading and Risk Management
Activities," that required revenues and costs associated with certain energy
contracts to be shown on a net basis in the income statement. Prior to adopting
EITF 02-3 and the rescission of EITF Issue No. 98-10, "Accounting for Contracts
Involved in Energy Trading and Risk Management Activities," our accounting
practice was to present all settled energy purchase or sale contracts within our
power risk management program on a gross basis in Operating Revenue - Electric
and in Operating Expenses - Fuel and Purchased Power. This meant that revenues
were recorded for the notional amount of the power sale contracts with a
corresponding charge to income for the costs of the energy that was generated or
for the notional amount of a purchased power contract. Upon adoption, EITF 02-3
requires that prior periods also be netted to conform to the current year
presentation. Adoption of EITF 02-3 did not have any impact on operating or net
income for any period or stockholder's equity. The operating revenues and costs
netted for the year ended December 31, 2002 were $458 million (2001 - $392
million), which reduced interchange revenues and purchased power costs by equal
amounts. SFAS 133 was adopted on January 1, 2001 and therefore, no netting was
required for the year ended December 31, 2000.

Electric margin increased $40 million for the year ended December 31, 2001
compared to 2000, primarily due to a $75 million reduction in the estimated
credits to Missouri electric customers and increased sales of emissions credits.
During the year ended December 31, 2001, we reduced the estimated credit to
Missouri electric customers previously recorded for an earnings sharing plan for
the plan year ended June 30, 2001 by $10 million, compared to estimated credits
of $65 million recorded in 2000. These increases were partially offset by a 17%
decrease in interchange sales. Our residential, commercial and industrial sales
were comparable to the prior year. The $10 million increase in fuel and
purchased power costs for 2001, compared to 2000, was primarily driven by
increased

16



purchased power, resulting from the Spring 2001 refueling outage at our Callaway
nuclear plant, in addition to higher blended fuel costs.

Gas Operations

Our gas margin decreased $6 million in 2002 as compared to 2001 with gas
revenues decreasing $17 million and costs decreasing by $11 million. The
decrease in margin was primarily due to warmer winter weather early in 2002,
partially offset by increased gas sales due to colder than normal temperatures
in late 2002.

Gas margin in 2001 increased $13 million compared to 2000, primarily due to
higher gas costs recovered through purchased gas adjustment clauses, partially
offset by lower total sales of 14% resulting from unusually warm winter weather.

Other Operating Expenses

Other Operations and Maintenance

Other operations and maintenance expenses increased $31 million in 2002
compared to 2001, primarily due to higher employee benefit costs ($24 million)
related to increasing healthcare costs and the investment performance of
employee benefit plan assets, higher wages, and higher plant maintenance
expenses. See also Equity Price Risk below for a discussion of our expectations
and plans regarding trends in employee benefit costs.

Other operations and maintenance expenses increased $38 million in 2001
compared to 2000, primarily due to higher employee benefits costs in 2001 ($20
million), resulting from increasing healthcare costs and the investment
performance of employee benefit plan assets, a refueling outage at Callaway in
2001 versus no refueling in 2000 and increased costs of professional services.
In 2000, we recorded a $17 million charge to earnings related to our withdrawal
from the Midwest Independent System Operator (Midwest ISO). The charge reduced
earnings $10 million, net of taxes. See Note 2 - Rate and Regulatory Matters to
our Financial Statements for further information regarding the Midwest ISO.

Ameren Services and AmerenEnergy provided services to us, including wages,
employee benefits and professional services that were included in other
operations and maintenance expenses. See Note 3 - Related Party Transactions to
our Financial Statements for further information.

Restructuring Charges

Voluntary retirement and other restructuring charges of $65 million in 2002
consisted primarily of a charge related to Ameren's voluntary retirement program
of $51 million based on voluntary retirements of approximately 230 of our
employees and additional employees providing support functions to us through
Ameren Services. These costs consisted primarily of special termination benefits
associated with our pension and post-retirement benefit plans. Most of the
employees who voluntarily retired will leave Ameren by March 2003. In addition,
in December 2002, Ameren announced its plans to retire 343 megawatts of
rate-regulated capacity at our Venice, Illinois plant, which resulted in a total
charge of approximately $14 million. See Note 10 - Voluntary Retirement and
Other Restructuring Charges to our Financial Statements for more information.

Depreciation and Amortization

Depreciation and amortization expenses increased $1 million in 2002 and $9
million in 2001 compared to the prior years. These net increases were primarily
due to our investment in combustion turbine electric generating plants,
coal-fired power plants and distribution plant. The increase in 2002 was
significantly offset by a reduction of depreciation rates ($15 million) based on
an updated analysis of asset values, service lives and accumulated depreciation
levels that was included in our 2002 Missouri electric rate case settlement.

Income Taxes

Income tax expense decreased $37 million in 2002 compared to 2001,
primarily due to the lower pretax income and a lower effective tax rate. Income
tax expense increased $6 million in 2001 compared to 2000, due to higher pretax
income, offset by a lower effective tax rate.


17



Other Taxes

Other tax expense increased $4 million in 2002 compared to 2001, primarily
due to higher gross receipts taxes resulting from increased residential and
commercial electric sales and higher payroll taxes resulting from increased
wages. Other tax expense increased $4 million in 2001 compared to 2000,
primarily due to a change in the property tax assessment in the state of
Missouri.

Other Income and Deductions

Other income and deductions (excluding income taxes) decreased $40 million
in 2002, compared to the prior year. The decrease was primarily due to the cost
of economic development and energy assistance programs included in the
settlement of the Missouri electric rate case ($26 million), lower intercompany
interest earned in 2002 on funds loaned to the utility money pool resulting from
lower average intercompany notes receivable balances ($7 million), and decreased
gains on energy trading contracts. These decreases were partially offset by an
increase in earnings from our ownership interest in EEI primarily resulting from
its sale of emission credits ($10 million). Other income and deductions
(excluding income taxes) increased $17 million in 2001, compared to 2000,
primarily due to gains on energy trading contracts ($8 million), decreased
charitable contributions ($5 million), contributions in aid of construction ($3
million) and life insurance proceeds. These increases were partially offset by
lower interest earned on short-term cash investments ($4 million) and lower
intercompany interest earned on funds loaned to the utility money pool resulting
from lower average intercompany notes receivable balances ($3 million). See Note
11 - Miscellaneous, Net to our Financial Statements for further information.

Interest

Interest expense decreased $8 million in 2002 compared to 2001, primarily
due to lower interest rates on our variable rate environmental debt obligations
and lower interest expense associated with a decreased balance under our nuclear
fuel lease, partially offset by increased short-term intercompany interest as a
result of our borrowings from the utility money pool in the current year.
Interest expense decreased $13 million in 2001 compared to 2000, primarily due
to lower interest expense associated with our nuclear fuel lease and a decrease
in interest expense associated with our variable rate environmental debt
obligations resulting from lower interest rates.


LIQUIDITY AND CAPITAL RESOURCES

Operating

Our cash flows provided by operating activities totaled $696 million for
2002, compared to $590 million for 2001 and $669 million for 2000. Cash provided
by operations increased in 2002, primarily as a result of higher cash earnings
resulting from favorable weather. This increase was partially offset by payments
of Missouri electric customer sharing credits under our now expired electric
alternative regulation plan ($40 million) and the timing of payments on accounts
payable and accrued taxes. Cash flow from operations decreased in 2001,
principally due to the timing of credits provided to our Missouri electric
customers and the changes in working capital requirements, partially offset by
increased earnings.

Our tariff-based gross margins continue to be our principal source of cash
from operating activities. Our diversified retail customer mix of residential,
commercial and industrial classes and a commodity mix of gas and electric
service provide a reasonably predictable source of cash flows. In addition, we
plan to utilize short-term debt to support normal operations and other temporary
capital requirements.

Pension Funding

Ameren made cash contributions totaling $31 million to Ameren's defined
benefit retirement plan during 2002. Our share of the cash contribution was
approximately $23 million, which includes our portion related to Ameren
Services. At December 31, 2002, Ameren recorded a minimum pension liability of
$102 million, net of taxes, which resulted in a charge to Accumulated Other
Comprehensive Income (OCI) and a reduction to stockholders' equity. Our share of
the minimum pension liability was approximately $62 million, net of taxes.

Based on the performance of plan assets through December 31, 2002, Ameren
expects to be required under the Employee Retirement Income Security Act of 1974
(ERISA) to fund approximately $150 million to $175 million annually, including
CILCORP, in 2005, 2006 and 2007 in order to maintain minimum funding levels for
its pension

18


plans. In addition, Ameren estimates the pension funding for CILCORP to be less
than $1 million in 2003 and approximately $5 million in 2004. We expect our
share of the annual funding in 2005, 2006 and 2007 to be between approximately
$110 million to $128 million, which includes our share related to employees of
Ameren Services. These amounts are estimates and may change based on actual
stock market performance, changes in interest rates and any pertinent changes in
government regulations. At December 31, 2002, Ameren's Net Benefit Obligation
was $1,587 million and its Fair Value of Plan Assets was $1,059 million. See
Benefit Plan Accounting under Accounting Matters - Critical Accounting Policies
below.

Investing

Our net cash used in investing activities was $454 million in 2002 compared
to $419 million in 2001 and $414 million in 2000. In 2002, construction
expenditures were $520 million (2001 - $587 million; 2000 - $316 million)
primarily related to various upgrades at our coal power plants and further
construction of combustion turbine generating units. In 2002, we placed into
service 240 megawatts (approximately $135 million) of combustion turbine
electric generation capacity at Bowling Green, Missouri.

For the five-year period 2003 through 2007, our construction expenditures
are estimated to approximate $2.0 billion to $2.5 billion, of which
approximately $700 million is expected in 2003. This estimate includes capital
expenditures related to the construction and acquisition from an affiliate of
combustion turbine generating facilities and the replacement of steam generators
at our Callaway nuclear plant. In addition, this estimate includes capital
expenditures for transmission, distribution and other generation-related
activities, as well as for compliance with new NOx (nitrogen oxide) control
regulations, as discussed in Environmental below.

As a part of the settlement of the Missouri electric rate case in 2002 (see
Regulatory Matters below), we committed to making $2.25 billion to $2.75 billion
in infrastructure investments from January 1, 2002 through June 30, 2006. These
investments include, among other things, the addition of more than 700 megawatts
of new generation capacity and the replacement of steam generators at our
Callaway nuclear plant. The requirements for 700 megawatts of new generation is
expected to be satisfied by the 240 megawatts added in 2002 as discussed above
and the proposed transfer at net book value (December 31, 2002 - approximately
$260 million) of approximately 550 megawatts of generation assets from
Generating Company, which is subject to receipt of necessary regulatory
approvals and is expected to be completed in 2003.

We intend to add 117 megawatts of capacity by 2005 and at least 330
megawatts of capacity by 2006. Total costs expected to be incurred for these
units approximate $175 million of which approximately $100 million was committed
as of December 31, 2002.

We continually review our generation portfolio and expected electrical
needs and, as a result, we could modify our plan for generation asset purchases,
which could include the timing of when certain assets will be added to, or
removed from our portfolio, the type of generation asset technology that will be
employed, or whether capacity may be purchased, among other things. Any changes
that we may plan to make for future generating needs could result in significant
capital expenditures or losses being incurred, which could be material.

Environmental

We are subject to various environmental regulations by federal, state and
local authorities. From the beginning phases of siting and development, to the
ongoing operation of existing or new electric generating, transmission and
distribution facilities, our activities involve compliance with diverse laws and
regulations that address emissions and impacts to air and water, special,
protected and cultural resources (such as wetlands, endangered species and
archeological/historical resources), chemical and waste handling and noise
impacts. Our activities require complex and often lengthy processes to obtain
approvals, permits, or licenses for new, existing, or modified facilities.
Additionally, the use and handling of various chemicals or hazardous materials
(including wastes) requires preparation of release prevention plans and
emergency response procedures. As new laws or regulations are promulgated, we
assess their applicability and implement the necessary modifications to our
facilities or their operations, as required.

The U.S. Environmental Protection Agency (EPA) issued a rule in October
1998 requiring 22 Eastern states and the District of Columbia to reduce
emissions of NOx in order to reduce ozone in the Eastern United States. Among
other things, the EPA's rule establishes an ozone season, which runs from May
through September and a NOx emission budget for each state, including Illinois.
The EPA rule requires states to implement controls sufficient to meet their NOx
budget by May 31, 2004.

19




In February 2002, the EPA proposed similar rules for Missouri where the
majority of our facilities are located. Assuming the Missouri rules are
ultimately finalized, we estimate spending approximately $170 million to comply
with these rules for NOx control on our generating system by 2006. This estimate
includes the assumption that the regulations will require the installation of
Selective Catalytic Reduction technology on some of our units, as well as
additional controls.

See Note 14 - Commitments and Contingencies to our Financial Statements for
further discussion of environmental matters and Note 15 - Callaway Nuclear Plant
to our Financial Statements for a discussion of Callaway nuclear plant
decommissioning costs.

Financing

Our cash flows used in financing activities totaled $248 million in 2002,
compared to $176 million in 2001 and $352 million in 2000. Our principal
financing activities for the three year period included the redemptions of
long-term debt and preferred stock and the payment of dividends, partially
offset by the issuance of long-term and short-term debt and intercompany notes
payable.

We are authorized by the SEC under the PUHCA to have up to $1 billion of
short-term unsecured debt instruments outstanding at any time.

Short-Term Debt and Liquidity

Short-term debt consists of commercial paper, intercompany borrowings
through Ameren's utility money pool and bank loans (maturities generally within
1 to 45 days). At December 31, 2002, Ameren and its subsidiaries had committed
credit facilities, expiring at various dates between 2003 and 2005, totaling
$695 million, excluding EEI facilities of $45 million and our nuclear fuel lease
facilities of $120 million. This amount includes $80 million of our committed
credit facilities and $615 million of committed credit facilities at Ameren and
AmerenCIPS. We access these combined facilities through Ameren's utility money
pool arrangement. AmerenCIPS and Ameren Services may also borrow under this
arrangement. These committed credit facilities are used to support our
commercial paper program under which $250 million was outstanding at December
31, 2002. Based on commercial paper outstanding at December 31, 2002, $445
million was unused and available under these committed credit facilities and
available to us through the utility money pool.

Subject to the receipt of regulatory approval, which is being pursued,
AmerenCILCO will participate in Ameren's utility money pool arrangement. At
December 31, 2002, CILCO had committed credit facilities, expiring at various
dates during 2003, totaling $60 million.

In July 2002, Ameren entered into new committed credit agreements for $400
million in revolving credit facilities to be used for general corporate
purposes, including support of commercial paper programs. We may access these
new credit facilities through the utility money pool. The $400 million in new
facilities includes a $270 million 364-day revolving credit facility and a $130
million 3-year revolving credit facility. The 3-year facility has a $50 million
sub-limit for the issuance of letters of credit. These new credit facilities
replaced our former $300 million revolving credit facility. These amounts are
included in the total committed credit facilities of $695 million mentioned
above.

Ameren had a $200 million committed credit facility which matured in
December 2002. Ameren expects to replace this bank credit agreement with two new
credit facilities and expects to extend or replace its other committed credit
facilities upon their respective maturities. These credit facilities make
borrowings available at various interest rates based on LIBOR, agreed rates and
other options.

In addition to committed credit facilities, a further source of liquidity
for Ameren is available cash and cash equivalents. At December 31, 2002, Ameren
had $628 million of cash, all of which was available for borrowings by us under
the utility money pool. In early 2003, Ameren paid a total of approximately $500
million of cash on hand to acquire CILCORP and Medina Valley.

EEI also has two bank credit agreements totaling $45 million that expire in
2003. At December 31, 2002, $27 million was unused and available under these
committed credit facilities.

We also have a lease agreement that provides for the financing of nuclear
fuel. At December 31, 2002, the maximum amount that could be financed under the
agreement was $120 million. At December 31, 2002, $113 million was financed
under the lease.


20

We rely on access to short-term and long-term capital markets as a
significant source of funding for capital requirements not satisfied by our
operating cash flows. The inability by us to raise capital on favorable terms,
particularly during times of uncertainty in the capital markets, could
negatively impact our ability to maintain and grow our businesses. Based on our
current credit ratings, we believe that we will continue to have access to the
capital markets. However, events beyond our control may create uncertainty in
the capital markets such that our cost of capital would increase or our ability
to access the capital markets would be adversely affected.

The following table summarizes available borrowing capacity under our
committed lines of credit and credit agreements as of December 31, 2002:

indefinite periods.
(c) Represents purchase contracts for coal, natural gas, nuclear fuel
(including our contractual obligation for fabricated nuclear fuel for the
years 2007 through 2012) and electric capacity.

Credit Agreement Provisions and Covenants

Our financial agreements include customary default provisions that could
impact the continued availability of credit or result in the acceleration of
repayment. Many of Ameren's and its subsidiaries' committed credit facilities
require the borrower to represent, in connection with any borrowing under the
facility, that no material adverse change has occurred since certain dates. None
of our, AmerenCIPS' or Ameren's financing arrangements contains credit rating
triggers, with the exception of certain ratings triggers within AmerenCILCO's
financing arrangements.

Covenants in Ameren's committed credit facilities require the maintenance
of the percentage of total debt to total capital of 60% or less for Ameren,
AmerenCIPS and us. One of our committed credit facilities contains a covenant
that requires us to maintain this ratio at 65% or less. As of December 31, 2002,
this ratio was approximately 50%, 50% and 43% for Ameren, AmerenCIPS and us,
respectively. Ameren's committed credit facilities also include indebtedness
cross default provisions that could trigger a default under these facilities in
the event any subsidiary of Ameren (subject to definition in the underlying
credit agreements), other than certain project finance subsidiaries, defaults on
indebtedness in excess of $50 million.

Most of Ameren's and its subsidiaries' committed credit facilities include
provisions related to the funded status of Ameren's pension plan. These
provisions either require Ameren to meet minimum ERISA funding requirements or
limit the unfunded liability status of the plan. Under the most restrictive of
these provisions impacting Ameren facilities totaling $400 million, an event of
default will result if the unfunded liability status (as defined in the
underlying credit agreements) of Ameren's pension plan exceeds $300 million in
the aggregate. Based on the most recent valuation report available to Ameren at
December 31, 2002, which was based on January 2002 asset and liability
valuations, the unfunded liability status (as defined) was $31 million. While an
updated valuation report will not be available until the second half of 2003,
Ameren believes that the unfunded liability status of our pension plans (as
defined) could exceed $300 million based on the investment performance of the
pension plan assets and interest rate changes since January 1, 2002. As a
result, Ameren may need to renegotiate the facility provisions,


terminate or replace the affected facilities, or fund any unfunded liability
shortfall. Should Ameren elect to terminate these facilities, we believe we
would otherwise have sufficient liquidity to manage our short-term funding
requirements.

At December 31, 2002, Ameren and its subsidiaries were in compliance with
their credit agreement provisions and covenants.

Off-Balance Sheet Arrangements

At December 31, 2002, neither Ameren, nor any of its subsidiaries,
including us, had any off-balance sheet financing arrangements, other than
operating leases entered into in the ordinary course of business. We do not
expect to engage in any significant off-balance sheet financing arrangements in
the near future.

Long-Term Debt

The following table summarizes our issuances and redemptions of long-term
debt for the years ended 2002, 2001 and 2000. For additional information related
to the terms and uses of these issuances and the sources of funds and terms for
redemptions, see Note 9 - Long-Term Debt and Capitalization to our Financial

In August 2002, a shelf registration statement filed by us with the SEC on
Form S-3 was declared effective. This statement authorized the offering from
time to time of up to $750 million of various forms of long-term debt and trust
preferred securities to refinance existing debt and preferred stock, and for
general corporate purposes, including the repayment of short-term debt incurred
to finance construction expenditures and other working capital needs. In 2002,
we issued $173 million under the shelf registration statement.

On March 10, 2003, we issued $184 million of 5.50% senior secured notes due
March 15, 2034 under the shelf registration statement. We expect to use the net
proceeds from this issuance of approximately $180 million along with other funds
to redeem prior to maturity $104 million principal amount of outstanding 8.25%
first mortgage bonds due October 15, 2022, at a redemption price of 103.61% of
par, plus accrued interest, and to repay short-term debt incurred to pay at
maturity $75 million principal amount of 8.33% first mortgage bonds that were
due in December 2002. At March 10, 2003, the amount remaining under the shelf
registration statement was $393 million.

We expect to fund maturities of long-term debt and contractual obligations
through a combination of cash flow from operations and external financing.

To issue first mortgage bonds and preferred stock, we must comply with
earnings tests contained in our respective mortgage indenture and Articles of
Incorporation. For the issuance of additional first mortgage bonds, generally,
earnings coverage of twice the annual interest charges on first mortgage bonds
outstanding and to be issued is required. Generally, for the issuance of
additional preferred stock, earnings coverage of at least two and one-half times
the annual dividend on preferred stock outstanding and to be issued is required
under our Articles of Incorporation. The ability to issue such securities in the
future will depend on coverage at that time. At December 31, 2002, we had and
expect to continue to have adequate coverage ratios for anticipated
requirements.

22



OUTLOOK

We believe there will be challenges to earnings in 2003 and beyond due to
industry-wide trends and company-specific issues. The following are expected to
put pressure on earnings in 2003 and beyond:

o Weak economic conditions, which impacts native load demand,
o Generally soft power prices in the Midwest are expected to limit the amount
of revenues we can generate by
marketing our excess power into the interchange markets,
o Our revenues will be reduced by a rate settlement approved in 2002 by the
Missouri Public Service Commission (MoPSC) that requires the phase-in of
$110 million of electric rate reductions from 2002 through 2004,
o The adverse effects of rising employee benefit costs, higher insurance
costs and increased security costs associated with additional measures we
have taken, or may have to take, at our Callaway nuclear plant related to
world events, and
o An assumed return to more normal weather patterns.

In late 2002, we and Ameren announced the following actions to mitigate the
effect of these challenges:

o A voluntary retirement program that was accepted by approximately 550
Ameren employees, including approximately 230 of our employees and
additional employees providing support functions to us through Ameren
Services,
o Modifications to retiree employee benefit plans to increase co-payments and
limit our overall cost,
o A wage freeze in 2003 for all management employees,
o Suspension of operations at two 1940's-era generating plants, including our
Venice plant, to reduce operating costs, and
o Reductions of 2003 expected capital expenditures.

We are pursuing a gas rate increase of approximately $4 million annually in
Illinois and are considering a filing in 2003 of a gas rate increase request in
Missouri. Ameren is also considering additional actions, including modifications
to active employee benefits, further staffing reductions and other initiatives.

In the ordinary course of business, we evaluate strategies to enhance our
financial position, results of operations and liquidity. These strategies may
include potential acquisitions, divestitures, opportunities to reduce costs or
increase revenues and other strategic initiatives in order to increase Ameren's
shareholder value. We are unable to predict which, if any, of these initiatives
will be executed, as well as the impact these initiatives may have on our future
financial position, results of operations or liquidity.

Labor Agreements

Certain employees of AmerenUE are represented by the International
Brotherhood of Electrical Workers (IBEW) and the International Union of
Operating Engineers (IUOE). These employees comprise approximately 75% of our
workforce. Labor agreements covering 10% of employees extend through 2006. Labor
agreements covering the remaining employees represented by IBEW and IUOE expire
by June 2003. We cannot predict what issues may be raised by the collective
bargaining units and, if raised, whether negotiations concerning such issues
will be successfully concluded.


REGULATORY MATTERS

Missouri

From July 1, 1995 through June 30, 2001, we operated under experimental
alternative regulation plans in Missouri that provided for the sharing of
earnings with customers if our regulatory return on equity exceeded defined
threshold levels. After our experimental alternative regulation plan for our
Missouri retail electric customers expired, the MoPSC Staff and others sought to
reduce our annual Missouri electric revenues by over $300 million. The MoPSC
Staff's recommendation was based on a return to traditional cost of service
ratemaking, a lowered return on equity, a reduction in our depreciation rates
and other cost of service adjustments.

23



In August 2002, a stipulation and agreement resolving this case became
effective following agreement by all parties to the case and approval by the
MoPSC. The stipulation and agreement includes the following principal features:

o The phase-in of $110 million of electric rate reductions through April
2004, $50 million of which was retroactively effective as of April 1, 2002,
$30 million of which will become effective on April 1, 2003 and $30 million
of which will become effective on April 1, 2004.
o A rate moratorium providing for no changes in rates before June 30, 2006,
subject to certain statutory and other exceptions.
o A commitment to contribute $14 million to programs for low income energy
assistance and weatherization, promotion of energy efficiency and economic
development in our service territory in 2002, with additional payments of
$3 million made annually on June 30, 2003 through June 30, 2006. This
obligation was expensed in 2002.
o A commitment to make $2.25 billion to $2.75 billion in critical energy
infrastructure investments from January 1, 2002 through June 30, 2006,
including, among other things, the addition of more than 700 megawatts of
new generation capacity and the replacement of steam generators at our
Callaway nuclear plant. The 700 megawatts of new generation is expected to
be satisfied by 240 megawatts that were added by us in 2002 and the
proposed transfer at net book value to us of approximately 550 megawatts of
generation assets from Generating Company, which is subject to receipt of
necessary regulatory approvals.
o An annual reduction in our depreciation rates by $20 million, retroactive
to April 1, 2002, based on an updated analysis of asset values, service
lives and accumulated depreciation levels.
o A one-time credit of $40 million which was accrued during the plan period.
The entire amount was paid to our Missouri retail electric customers in
2002 for the settlement of the final sharing period under the alternative
regulation plan that expired June 30, 2001.

ACCOUNTING MATTERS

Critical Accounting Policies

Preparation of the financial statements and related disclosures in
compliance with generally accepted accounting principles requires the
application of appropriate technical accounting rules and guidance, as well as
the use of estimates. Our application of these policies involves judgments
regarding many factors, which, in and of themselves, could materially impact the
financial statements and disclosures. A future change in the assumptions or
judgments applied in determining the following matters, among others, could have
a material impact on future financial results. In the table below, we have
outlined those accounting policies that we believe are most difficult,
subjective or complex:

24



Basis for Judgment
We determine that costs are recoverable based on previous rulings by state
regulatory authorities in jurisdictions where we operate or other factors
that lead us to believe that cost recovery is probable.

plant are accurate. See Note 15 - Callaway
Nuclear Plant to our Financial Statements.

Basis for Judgment
We determine that decommissioning costs are reasonable, or require
adjustment, based on third party decommissioning studies that are completed
every three years, the evaluation of our facilities by our engineers and
the monitoring of industry trends.


Environmental Costs

We accrue for all known environmental o Extent of contamination

Basis for Judgment
We determine the proper amounts to accrue for environmental contamination
based on internal and third party estimates of clean-up costs in the
context of current remediation standards and available technology.


Unbilled Revenue

At the end of each period, we estimate, based o Projecting customer energy usage
on expected usage, the amount of revenue to o Estimating impacts of weather and other
record for services that have been provided usage-affecting factors for the unbilled period

can be up to one month.

Basis for Judgment
We determine the proper amount of unbilled revenue to accrue each period
based on the volume of energy delivered as valued by a model of billing
cycles and historical usage rates and growth by customer class for our
service area, as adjusted for the modeled impact of seasonal and weather
variations based on historical results.


Benefit Plan Accounting

Based on actuarial calculations, we accrue o Future rate of return on pension and other plan

25



Basis for Judgment
We utilize a third party consultant to assist us in evaluating and
recording the proper amount for future employee benefits. Our ultimate
selection of the discount rate, healthcare trend rate and expected rate of
return on pension assets is based on our review of available current,
historical and projected rates, as applicable.

external sources and prices based on internal models and other valuation
methods to determine the fair market value of derivative financial
instruments.



Impact of Future Accounting Pronouncements

See Note 1 - Summary of Significant Accounting Policies to our Financial
Statements.


EFFECTS OF INFLATION AND CHANGING PRICES

Our rates for retail electric and gas utility service are generally
regulated by the MoPSC and the Illinois Commerce Commission. Non-retail electric
rates are regulated by the Federal Energy Regulatory Commission (FERC). Our
Missouri electric rates have been set through June 30, 2006, as part of the
settlement of our Missouri rate case and our Illinois electric rates are
legislatively fixed through January 1, 2007. Inflation affects our operations,
earnings, stockholder's equity and financial performance.

The current replacement cost of our utility plant substantially exceeds our
recorded historical cost. Under existing regulatory practice, only the
historical cost of plant is recoverable from customers. As a result, cash flows
designed to provide recovery of historical costs through depreciation might not
be adequate to replace plant in future years.

In our retail electric utility jurisdictions, there are no provisions for
adjusting for changes in the cost of fuel for electric generation. In our retail
gas utility jurisdictions, changes in gas costs are generally reflected in
billings to gas customers through purchased gas adjustment clauses. We are
impacted by changes in market prices for natural gas to the extent we must
purchase natural gas to run our combustion turbine electric generators. We have
structured various supply agreements to maintain access to multiple gas pools
and supply basins to minimize the impact to the financial statements. See
discussion below under Commodity Price Risk for further information.



26



QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of changes in value of a physical asset or
financial instrument, derivative or non-derivative, caused by fluctuations in
market variables (e.g. interest rates, etc.). The following discussion of
Ameren's, including AmerenUE's, risk management activities includes
"forward-looking" statements that involve risks and uncertainties. Actual
results could differ materially from those projected in the "forward-looking"
statements. Ameren handles market risks in accordance with established policies,
which may include entering into various derivative transactions. In the normal
course of business, Ameren and AmerenUE also face risks that are either
non-financial or non-quantifiable. Such risks principally include business,
legal and operational risks and are not represented in the following discussion.

Ameren's risk management objective is to optimize its physical generating
assets within prudent risk parameters. Our risk management policies are set by a
Risk Management Steering Committee, which is comprised of senior-level Ameren
officers.

Interest Rate Risk

We are exposed to market risk through changes in interest rates associated
with both long-term and short-term variable-rate debt and fixed-rate debt. We
manage our interest rate exposure by controlling the amount of these instruments
we hold within our total capitalization portfolio and by monitoring the effects
of market changes in interest rates.

Utilizing our debt outstanding at December 31, 2002, if interest rates
increase by 1%, our annual interest expense would increase by approximately $8
million and net income would decrease by approximately $5 million. The model
does not consider the effects of the reduced level of potential overall economic
activity that would exist in such an environment. In the event of a significant
change in interest rates, management would likely take actions to further
mitigate our exposure to this market risk. However, due to the uncertainty of
the specific actions that would be taken and their possible effects, the
sensitivity analysis assumes no change in our financial structure.

Credit Risk

Credit risk represents the loss that would be recognized if counterparties
fail to perform as contracted. New York Mercantile Exchange (NYMEX) traded
futures contracts are supported by the financial and credit quality of the
clearing members of the NYMEX and have nominal credit risk. On all other
transactions, we are exposed to credit risk in the event of nonperformance by
the counterparties in the transaction.

Our physical and financial instruments are subject to credit risk
consisting of trade accounts receivables and executory contracts with market
risk exposures. The risk associated with trade receivables is mitigated by the
large number of customers in a broad range of industry groups comprising our
customer base. No customer represents greater than 10% of our accounts
receivable. Our revenues are primarily derived from sales of electricity and
natural gas to customers in Missouri and Illinois. We analyze each
counterparty's financial condition prior to entering into sales, forwards,
swaps, futures or option contracts. We also establish credit limits for these
counterparties and monitor the appropriateness of these limits on an ongoing
basis through a credit risk management program which involves daily exposure
reporting to senior management, master trading and netting agreements, and
credit support management such as letters of credit and parental guarantees.

Commodity Price Risk

We are exposed to changes in market prices for natural gas, fuel and
electricity. We utilize several techniques to mitigate risk, including utilizing
derivative financial instruments. A derivative is a contract whose value is
dependent on, or derived from, the value of some underlying asset. The
derivative financial instruments that we use (primarily forward contracts,
futures contracts, option contracts and financial swap contracts) are dictated
by risk management policies.

With regard to our natural gas utility business, our exposure to changing
market prices is in large part mitigated by the fact that we have gas cost
recovery mechanisms in place in both Missouri and Illinois. These gas cost
recovery mechanisms allow us to pass on to our retail customers our prudently
incurred costs of natural gas.

AmerenEnergy Fuels and Services Company is responsible for providing fuel
procurement and gas supply services on behalf of Ameren's operating subsidiaries
and for managing fuel and natural gas price risks. Fixed price forward
contracts, as well as futures, options and financial swaps are all instruments,
which may be used to manage

27



these risks. The majority of our fuel supply contracts are physical forward
contracts. Since we do not have a provision similar to the purchased gas
adjustment clauses for our electric operations, we have entered into several
long-term contracts with various suppliers to purchase coal and nuclear fuel in
order to manage our exposure to fuel prices. See Note 14 - Commitments and
Contingencies to our Financial Statements for further information. We have
satisfied 77%, 20% and 3% of our 2002 power supply needs through coal, nuclear
and hydro, respectively. Approximately 97% of the required 2003 supply and
approximately 79% of the required 2004 supply of coal for our coal-fired power
plants has been acquired at fixed prices. As such, we have minimal coal price
risk for the remainder of 2003 and 2004. At December 31, 2002, approximately 22%
of our coal requirements for 2005 through 2007 were covered by contracts. In
addition, we are exposed to changes in market prices for natural gas to the
extent we must purchase natural gas to run our combustion turbine generators.
Our natural gas procurement strategy is designed to ensure reliable and
immediate delivery of natural gas to our peaking units by optimizing
transportation and storage options and minimizing cost and price risk by
structuring various supply agreements to maintain access to multiple gas pools
and supply basins and reducing the impact of price volatility. At December 31,
2002, approximately 33% of our 2003 natural gas requirements for generation were
covered by contracts.

Although we cannot completely eliminate the effects of gas price
volatility, our strategy is designed to minimize the effect of market conditions
on our results of operations. Our gas procurement strategy includes procuring
natural gas under a portfolio of agreements with price structures, including
fixed price, indexed price and embedded price hedges such as caps and collars.
Our strategy also utilizes physical assets through storage, operator and
balancing agreements to minimize price volatility. Our electric marketing
strategy is to extract additional value from our generation facilities by
selling energy in excess of needs into the long-term and short-term markets for
term sales, and purchasing energy when the market price is less than the cost of
generation. Our primary use of derivatives has involved transactions that are
expected to reduce price risk exposure for us.

With regard to our exposure to commodity price risk for purchased power and
excess electricity sales, Ameren has a subsidiary, AmerenEnergy whose primary
responsibility includes managing market risks associated with changing market
prices for electricity purchased and sold on behalf of AmerenUE and our
affiliate, Generating Company.

Equity Price Risk

We, along with other subsidiaries of Ameren, are a participant in Ameren's
defined benefit plans and postretirement benefit plans and are responsible for
our proportional share of the costs. Ameren's costs of providing
non-contributory defined benefit retirement and postretirement benefit plans are
dependent upon a number of factors, such as the rates of return on plan assets,
discount rate, the rate of increase in health care costs and contributions made
to the plans. The market value of Ameren's plan assets has been affected by
declines in the equity market since 2000 for the pension and postretirement
plans. As a result, at December 31, 2002, we recognized an additional minimum
pension liability as prescribed by SFAS No. 87, "Employers' Accounting for
Pensions." The liability resulted in a reduction to OCI of $62 million, net of
taxes. The amount of the liability was the result of asset returns experienced
through 2002, interest rates and Ameren's contributions to the plan during 2002.
In future years, the liability recorded, the costs reflected in net income or
OCI, or cash contributions to the plans could increase materially without a
recovery in equity markets in excess of our assumed return on plan assets. If
the fair value of the plan assets were to grow and exceed the accumulated
benefit obligations in the future, then the recorded liability would be reduced
and a corresponding amount of equity would be restored in the Balance Sheet. See
Liquidity and Capital Resources - Operating.

We also maintain trust funds, as required by the Nuclear Regulatory
Commission and Missouri and Illinois state laws, to fund certain costs of
nuclear decommissioning. See Note 15 - Callaway Nuclear Plant to our Financial
Statements for further information. As of December 31, 2002, these funds were
invested primarily in domestic equity securities (62%), debt securities (35%)
and cash and cash equivalents (3%) and totaled $172 million at fair value. By
maintaining a portfolio that includes long-term equity investments, we seek to
maximize the returns to be utilized to fund nuclear decommissioning costs.
However, the equity securities included in our portfolio are exposed to price
fluctuations in equity markets and the fixed-rate, fixed-income securities are
exposed to changes in interest rates. We actively monitor our portfolio by
benchmarking the performance of our investments against certain indices and by
maintaining, and periodically reviewing, established target allocation
percentages of the assets of our trusts to various investment options. Our
exposure to equity price market risk is, in large part, mitigated due to the
fact that we are currently allowed to recover decommissioning costs in our
rates.

28



Fair Value of Contracts

We utilize derivatives principally to manage the risk of changes in market
prices for natural gas, fuel, electricity and emission credits. Price
fluctuations in natural gas, fuel and electricity cause:

o an unrealized appreciation or depreciation of our firm commitments to
purchase or sell when purchase or sales prices under the firm commitment
are compared with current commodity prices;
o market values of fuel and natural gas inventories or purchased power to
differ from the cost of those commodities under the firm commitment; and
o actual cash outlays for the purchase of these commodities to differ from
anticipated cash outlays.

The derivatives that we use to hedge these risks are dictated by risk
management policies and include forward contracts, futures contracts, options
and swaps. We continually assess our supply and delivery commitment positions
against forward market prices and internally forecast forward prices and modify
our exposure to market, credit and operational risk by entering into various
offsetting transactions. In general, we believe these transactions serve to
reduce our price risk. See Note 4 - Derivative Financial Instruments to our
Financial Statements for further information.

The following summarizes the favorable (unfavorable) changes in the fair
value of all contracts marked to market during 2002 and 2001:

FORWARD-LOOKING STATEMENTS

Statements made in this report which are not based on historical facts are
"forward-looking" and, accordingly, involve risks and uncertainties that could
cause actual results to differ materially from those discussed. Although such
"forward-looking" statements have been made in good faith and are based on
reasonable assumptions, there is no assurance that the expected results will be
achieved. These statements include (without limitation) statements as to future
expectations, beliefs, plans, strategies, objectives, events, conditions and
financial performance. In connection with the "safe harbor" provisions of the
Private Securities Litigation Reform Act of 1995, we are providing this
cautionary statement to identify some important factors that could cause actual
results to differ materially from those anticipated. The following factors, in
addition to those discussed elsewhere in this report and in subsequent
securities filings, could cause results to differ materially from management
expectations as suggested by such "forward-looking" statements:

o the effects of the stipulation and agreement relating to our Missouri
electric excess earnings complaint case and other regulatory actions,
including changes in regulatory policy;
o changes in laws and other governmental actions, including monetary and
fiscal policies;
o the impact on us of current regulations related to the opportunity for
customers to choose alternative energy suppliers in Illinois;
o the effects of increased competition in the future due to, among other
things, deregulation of certain aspects of our business at both the state
and federal levels;
o the effects of participation in a FERC-approved Regional Transmission
Organization, including activities associated with the Midwest ISO;
o availability and future market prices for fuel and purchased power,
electricity and natural gas, including the use of financial and derivative
instruments and volatility of changes in market prices;
o the cost of commodities, such as natural gas, used in the production of
electricity and our ability to recover such increased cost;
o average rates for electricity in the Midwest;
o business and economic conditions;
o the impact of the adoption of new accounting standards on the application
of appropriate technical accounting rules and guidance;
o interest rates and the availability of capital;
o actions of rating agencies and the effects of such actions;
o weather conditions;
o generation plant construction, installation and performance;
o operation of nuclear power facilities and decommissioning costs;
o the effects of strategic initiatives, including acquisitions and
divestitures;
o the impact of current environmental regulations on utilities and generating
companies and the expectation that more stringent requirements will be
introduced over time, which could potentially have a negative financial
effect;
o future wages and employee benefit costs, including changes in returns of
benefit plan assets;
o disruptions of the capital markets or other events making Ameren's or our
access to necessary capital more difficult or costly;
o competition from other generating facilities, including new facilities that
may be developed in the future;
o cost and availability of transmission capacity for the energy generated by
our generating facilities or required to satisfy our energy sales; and
o legal and administrative proceedings.

Given these uncertainties, undue reliance should not be placed on these
forward-looking statements. Except to the extent required by the federal
securities laws, we undertake no obligation to publicly update or revise any
forward-looking statements, whether as a result of new information, future
events or otherwise.

UNION ELECTRIC COMPANY
NOTES TO FINANCIAL STATEMENTS
DECEMBER 31, 2002

NOTE 1 - Summary of Significant Accounting Policies

General

Union Electric Company, headquartered in St. Louis, Missouri, is a
wholly-owned subsidiary of Ameren Corporation (Ameren) and operates as AmerenUE.
Our principal business is the rate-regulated generation, transmission and
distribution of electricity, and the rate-regulated distribution of natural gas
to residential, commercial, industrial and wholesale users in Missouri and
Illinois. Ameren is a public utility holding company registered with the
Securities and Exchange Commission (SEC) under the Public Utility Holding
Company Act of 1935 (PUHCA) and is also headquartered in St. Louis, Missouri.
Ameren's principal business is the generation, transmission and distribution of
electricity, and the distribution of natural gas to residential, commercial,
industrial and wholesale users in the central United States. In addition to us,
Ameren's principal subsidiaries and our affiliates are as follows:

o Central Illinois Public Service Company, which operates a rate-regulated
electric and natural gas transmission and distribution business in Illinois
as AmerenCIPS.
o Central Illinois Light Company is a subsidiary of CILCORP Inc. (CILCORP),
which operates a rate-regulated electric generation, transmission and
distribution business, an electric generation business, and a
rate-regulated natural gas distribution business in Illinois as
AmerenCILCO. Ameren completed its acquisition of CILCORP on January 31,
2003 from The AES Corporation (AES). See Note 17 - Subsequent Event for
further information.
o AmerenEnergy Resources Company (Resources Company), which consists of non
rate-regulated operations. Subsidiaries include AmerenEnergy Generating
Company (Generating Company) that operates non rate-regulated electric
generation in Missouri and Illinois, AmerenEnergy Marketing Company
(Marketing Company), which markets power for periods over one year,
AmerenEnergy Fuels and Services Company, which procures fuel and manages
the related risks for Ameren affiliated companies and AmerenEnergy Medina
Valley Cogen (No. 4), LLC, which indirectly owns a 40 megawatt, gas-fired
electric co-generation plant. On February 4, 2003, Ameren completed its
acquisition of AES Medina Valley Cogen (No. 4), LLC (Medina Valley) from
AES and renamed it AmerenEnergy Medina Valley Cogen (No. 4), LLC. See Note
17 - Subsequent Event for further information.
o AmerenEnergy, Inc. (AmerenEnergy), which serves as a power marketing and
risk management agent for Ameren affiliated companies for transactions of
primarily less than one year.
o Electric Energy, Inc. (EEI), which operates electric generation and
transmission facilities in Illinois. We have a 40% ownership interest in
EEI and have accounted for it under the equity method of accounting.
Resources Company also owns a 20% interest in EEI.
o Ameren Services Company (Ameren Services), which provides shared support
services to Ameren and its subsidiaries, including us. Charges are based
upon the actual costs incurred by Ameren Services, as required by the
PUHCA.

When we refer to AmerenUE, our, we or us, we are referring to Union
Electric Company and in some cases our agents, AmerenEnergy and Ameren Energy
Fuels and Services Company. All tabular dollar amounts are in millions, unless
otherwise indicated.

The accounting policies of AmerenUE conform to generally accepted
accounting principles in the United States (GAAP). Our financial statements
reflect all adjustments (which include normal, recurring adjustments) necessary,
in our opinion, for a fair presentation of our results. The preparation of
financial statements in conformity with GAAP requires management to make certain
estimates and assumptions. Such estimates and assumptions affect reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reported period. Actual results could differ
from those estimates. Certain reclassifications have been made to prior years'
financial statements to conform to 2002 reporting.

Regulation

We are regulated by the Missouri Public Service Commission (MoPSC),
Illinois Commerce Commission (ICC), Nuclear Regulatory Commission (NRC), the
Federal Energy Regulatory Commission (FERC) and the SEC. See Note 2 - Rate and
Regulatory Matters for further information.


36



In accordance with Statement of Financial Accounting Standards (SFAS) No.
71, "Accounting for the Effects of Certain Types of Regulation," we defer
certain costs pursuant to actions of our regulators and are currently recovering
such costs in rates charged to customers.

At December 31, 2002 and 2001, we had recorded the following regulatory
assets and regulatory liabilities:

- --------------------------------------------------------------------------------
2002 2001
- --------------------------------------------------------------------------------
Regulatory assets:
Income taxes (a)(f) $526 $604
Callaway costs (b) 81 84
Unamortized loss on reacquired debt (c)(f) 27 23
Other (d)(f) 25 27
- --------------------------------------------------------------------------------
Regulatory assets $659 $738
- --------------------------------------------------------------------------------
Regulatory liabilities:
Income taxes (e) $121 $137
- --------------------------------------------------------------------------------
(a) See Note 12 - Income Taxes for amortization period. Amount represents SFAS
109 deferred tax asset.
(b) Represents Callaway nuclear plant operations and maintenance expenses,
property taxes and carrying costs incurred between the plant in-service
date and the date the plant was reflected in rates. These costs are being
amortized over the remaining life of the plant's current operating license
through 2024.
(c) Represents losses related to refunded debt. These amounts are being
amortized over the lives of the related new debt issues or the remaining
lives of the old debt issues if no new debt was issued.
(d) Represents Y2K expenses being amortized over 6 years starting in 2002 in
conjunction with the settlement of our Missouri electric rate case and a
Department of Energy Decommissioning assessment being amortized over 14
years through 2007. In addition, amount includes the portion of
merger-related expenses applicable to the Missouri retail jurisdiction
which are being amortized through 2008 based on a MoPSC order.
(e) See Note 12 - Income Taxes for amortization period. Represents unamortized
portion of investment tax credit and federal excess taxes.
(f) These assets do not earn a return.

We continually assess the recoverability of our regulatory assets. Under
current accounting standards, regulatory assets are written off to earnings when
it is no longer probable that such amounts will be recovered through future
revenues. Electric industry restructuring legislation may impact the
recoverability of regulatory assets in the future.

Property and Plant

The cost of additions to and betterments of units of property and plant is
capitalized. Cost includes labor, material, applicable taxes and overheads. An
allowance for funds used during construction is also added for our
rate-regulated assets. Maintenance expenditures and the renewal of items not
considered units of property are charged to income as incurred. When units of
depreciable property are retired, the original cost and removal cost, less
salvage value, are charged to accumulated depreciation. See Accounting Changes
and Other Matters relating to SFAS No. 143, "Accounting for Asset Retirement
Obligations," and Note 5 - Property and Plant, Net for further information.

Depreciation

Depreciation is provided over the estimated lives of the various classes of
depreciable property by applying composite rates on a straight-line basis. The
provision for depreciation in 2002, 2001 and 2000 was approximately 3% of the
average depreciable cost.

Allowance for Funds Used During Construction

Allowance for funds used during construction (AFC) is a utility industry
accounting practice whereby the cost of borrowed funds and the cost of equity
funds (preferred and common stockholders' equity) applicable to rate-regulated
construction expenditures are capitalized as a cost of construction. AFC does
not represent a current source of cash funds. This accounting practice offsets
the effect on earnings of the cost of financing current construction, and treats
such financing costs in the same manner as construction charges for labor and
materials.

Under accepted ratemaking practice, cash recovery of AFC, as well as other
construction costs, occurs when completed projects are placed in service and
reflected in customer rates. The AFC rates were 5% during 2002 and 10% during
both 2001 and 2000.


37



Impairment of Long-Lived Assets

We evaluate long-lived assets for impairment when events or changes in
circumstances indicate that the carrying value of such assets may not be
recoverable. The determination of whether impairment has occurred is based on an
estimate of undiscounted cash flows attributable to the assets, as compared with
the carrying value of the assets. If impairment has occurred, the amount of the
impairment recognized is determined by estimating the fair value of the assets
and recording a provision for loss if the carrying value is greater than the
fair value. See Accounting Changes and Other Matters relating to SFAS No. 144,
"Accounting for the Impairment or Disposal of Long-Lived Assets."

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and temporary investments
purchased with an original maturity of three months or less.

Unamortized Debt Discount, Premium and Expense

Discount, premium and expense associated with long-term debt are amortized
over the lives of the related issues.

Revenue

We accrue an estimate of electric and gas revenues for service rendered,
but unbilled, at the end of each accounting period.

Interchange revenues included in Operating Revenues - Electric were $258
million for the year ended December 31, 2002 (2001 - $375 million; 2000 - $435
million). See Emerging Issues Task Force (EITF) Issue 02-3, "Issues Involved in
Accounting for Derivative Contracts Held for Trading Purposes and Contracts
Involved in Energy Trading and Risk Management Activities," discussion under
Accounting Changes and Other Matters for further information.

Purchased Power

Purchased power included in Operating Expenses - Fuel and Purchased Power
was $206 million for the year ended December 31, 2002 (2001 - $383 million; 2000
- - $368 million). See EITF 02-3 discussion under Accounting Changes and Other
Matters for further information.

Fuel and Gas Costs

In our retail electric utility jurisdictions, there are no provisions for
adjusting rates for changes in the cost of fuel for electric generation. In our
retail gas utility jurisdictions, changes in gas costs are generally reflected
in billings to gas customers through purchased gas adjustment clauses.

The cost of nuclear fuel is amortized to fuel expense on a
unit-of-production basis. Spent fuel disposal cost is charged to expense based
on net kilowatthours generated and sold.

Excise Taxes

Excise taxes on Missouri electric and gas, and Illinois gas customer bills
are imposed on us and are recorded gross in Operating Revenues and Other Taxes.
Excise taxes recorded in Operating Revenues and Other Taxes for 2002 were $103
million (2001- $101 million; 2000 - $102 million). Excise taxes applicable to
Illinois electric customer bills are imposed on the consumer and are recorded as
tax collections payable and included in Taxes Accrued on the Balance Sheet.

Income Taxes

We are included in the consolidated federal income tax return filed by
Ameren. As a subsidiary of Ameren, we could be considered jointly and severably
liable for assessments of additional tax on the consolidated group. Income taxes
are allocated to the Ameren subsidiaries based on their respective taxable
income or loss. Our provision for income taxes has been presented based on
federal and state taxes we would have presented on a stand-alone

38




company basis. Deferred tax assets and liabilities are recognized for the tax
consequences of transactions that have been treated differently for financial
reporting and tax return purposes, measured using statutory tax rates.

Investment tax credits utilized in prior years were deferred and are being
amortized over the useful lives of the related properties.

Accounting Changes and Other Matters

In January 2001, we adopted SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." The impact of that adoption resulted in a
cumulative effect charge of $5 million, net of taxes, to the income statement,
and a cumulative effect adjustment of $8 million, net of taxes, to Accumulated
Other Comprehensive Income (OCI), which reduced common stockholder's equity. See
Note 4 - Derivative Financial Instruments for further information.

In January 2002, we adopted SFAS No. 141, "Business Combinations," and SFAS
No. 142, "Goodwill and Other Intangible Assets." SFAS 141 requires business
combinations to be accounted for under the purchase method of accounting, which
requires one party in the transaction to be identified as the acquiring
enterprise and for that party to allocate the purchase price to the assets and
liabilities of the acquired enterprise based on fair market value. SFAS 142
requires goodwill and indefinite-lived intangible assets recorded in the
financial statements to be tested for impairment at least annually, rather than
amortized over a fixed period, with impairment losses recorded in the income
statement. SFAS 141 and SFAS 142 did not have any effect on our financial
position, results of operations or liquidity upon adoption. SFAS 141 and SFAS
142 were utilized for Ameren's acquisition of CILCORP Inc. and AES Medina Valley
Cogen (No. 4), LLC. See Note 17 - Subsequent Event for further information.

We are adopting SFAS 143 in the first quarter of 2003. SFAS 143 provides
the accounting requirements for asset retirement obligations associated with
tangible, long-lived assets. SFAS 143 requires us to record the estimated fair
value of legal obligations associated with the retirement of tangible long-lived
assets in the period in which the liabilities are incurred and to capitalize a
corresponding amount as part of the book value of the related long-lived asset.
In subsequent periods, we are required to adjust asset retirement obligations
based on changes in estimated fair value, and the corresponding increases in
asset book values are depreciated over the useful life of the related asset.
Uncertainties as to the probability, timing or cash flows associated with an
asset retirement obligation affect our estimate of fair value.

Upon adoption of this standard, we expect to recognize additional asset
retirement obligations of approximately $215 million and a net increase in net
property and plant of approximately $75 million related primarily to the
Callaway nuclear decommissioning costs and also to retirement costs for a river
structure. These asset retirement obligations are in addition to liabilities we
have previously recorded related to our future obligation to decommission the
Callaway nuclear plant.

The difference between the net asset and the liability recorded upon
adoption of SFAS 143 related to rate-regulated assets will be recorded as an
additional regulatory asset because we expect to continue to recover the cost of
Callaway nuclear decommissioning and other costs of removal in electric rates.

In addition to these obligations, we have determined that certain other
asset retirement obligations exist. However, we are unable to estimate the fair
value of those obligations because the probability, timing or cash flows
associated with the obligations are indeterminable. We do not believe that these
obligations, when incurred, will have a material adverse impact on our financial
position, results of operations or liquidity.

SFAS 143 also may require a change in the depreciation methodology we have
historically utilized for our rate-regulated operations. Historically, we have
included an estimated cost of dismantling and removing plant from service upon
retirement. This practice is currently required by regulators in the
jurisdictions in which we operate. As a result, though we are still assessing
the impact of SFAS 143 on our rate-regulated depreciation methodology, we do not
believe any such impact will affect our results of operations. However, if we
are required to remove accrued dismantling and removal costs from accumulated
depreciation, where they are currently embedded, our asset and liability
balances could be materially increased.

On January 1, 2002, we adopted SFAS 144. SFAS 144 addresses the financial
accounting and reporting for the impairment or disposal of long-lived assets and
supersedes SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and
for Long-Lived Assets to Be Disposed Of." SFAS 144 retains the guidance related
to calculating and recording impairment losses, but adds guidance on the
accounting for discontinued operations, previously accounted for under
Accounting Principles Board Opinion No. 30, "Reporting the Results of Operations

39



- - Reporting the Effects of a Segment of a Business, and Extraordinary, Unusual
and Infrequently Occurring Events and Transactions." SFAS 144 did not have any
effect on our financial position, results of operations or liquidity in 2002.

In June 2002, the FASB issued SFAS No. 146, "Accounting for Costs
Associated with Exit or Disposal Activities." SFAS 146 requires an entity to
recognize and measure at fair value a liability for a cost associated with an
exit or disposal activity in the period in which the liability is incurred and
nullifies EITF Issue No. 94-3, "Liability Recognition for Certain Employee
Termination Benefits and Other Costs to Exit an Activity (Including Certain
Costs Incurred in a Restructuring)." SFAS 146 is effective for exit or disposal
activities that are initiated after December 31, 2002.

During 2002, we adopted the provisions of EITF 02-3 that required revenues
and costs associated with certain energy contracts to be shown on a net basis in
the income statement. Prior to adopting EITF 02-3 and the rescission of EITF
Issue No. 98-10, "Accounting for Contracts Involved in Energy Trading and Risk
Management Activities," our accounting practice was to present all settled
energy purchase or sale contracts within our power risk management program on a
gross basis in Operating Revenues - Electric and in Operating Expenses - Fuel
and Purchased Power. This meant that revenues were recorded for the notional
amount of the power sale contracts with a corresponding charge to income for the
costs of the energy that was generated, or for the notional amount of a
purchased power contract.

In October 2002, the EITF reached a consensus to rescind EITF 98-10. The
effective date for the full rescission of Issue 98-10 was for fiscal periods
beginning after December 15, 2002, with early adoption permitted. In addition,
the EITF reached a consensus in October 2002 that all SFAS 133 trading
derivatives (subsequent to the rescission of Issue EITF 98-10) should be shown
net in the income statement, whether or not physically settled. This consensus
applies to all energy and non-energy related trading derivatives that meet the
definition of a derivative pursuant to SFAS 133. We have adopted and applied
this guidance to 2002 and 2001, which had no impact on previously reported
earnings or stockholder's equity. The adoption of EITF 02-3, the rescission of
EITF 98-10 and the related transition guidance resulted in netting of energy
contracts and lowered our reported revenues and costs with no impact on
earnings. The following table summarizes the impact of energy contract netting
for the years ended December 31, 2001 and 2000:

- --------------------------------------------------------------------------------
2001 2000
- --------------------------------------------------------------------------------
Previously reported gross operating revenues $3,178 $2,720
Revenues and costs netted (a) 392 -
- --------------------------------------------------------------------------------
Net operating revenues reported $2,786 $2,720
- --------------------------------------------------------------------------------
(a) Revenues and costs netted for the year ended December 31, 2002 were $458
million. SFAS 133 was adopted on January 1, 2001 and therefore, no netting
was required for the year ended December 31, 2000.


NOTE 2 - Rate and Regulatory Matters

Missouri Electric

MoPSC Rate Case

From July 1, 1995 through June 30, 2001, we operated under experimental
alternative regulation plans in Missouri that provided for the sharing of
earnings with customers if our regulatory return on equity exceeded defined
threshold levels. After our experimental alternative regulation plan for our
Missouri retail electric customers expired, the MoPSC Staff and others sought to
reduce our annual Missouri electric revenues by over $300 million. The MoPSC
Staff's recommendation was based on a return to traditional cost of service
ratemaking, a lowered return on equity, a reduction in our depreciation rates
and other cost of service adjustments

In August 2002, a stipulation and agreement resolving this case became
effective following agreement by all parties to the case and approval by the
MoPSC. The stipulation and agreement includes the following principal features:

o The phase-in of $110 million of electric rate reductions through April
2004, $50 million of which was retroactively effective as of April 1, 2002,
$30 million of which will become effective on April 1, 2003, and $30
million of which will become effective on April 1, 2004.
o A rate moratorium providing for no changes in rates before June 30, 2006,
subject to certain statutory and other exceptions.


40



o A commitment to contribute $14 million to programs for low income energy
assistance and weatherization, promotion of energy efficiency and economic
development in our service territory in 2002, with additional payments of
$3 million made annually on June 30, 2003 through June 30, 2006. This
obligation was expensed in 2002.
o A commitment to make $2.25 billion to $2.75 billion in critical energy
infrastructure investments from January 1, 2002 through June 30, 2006,
including, among other things, the addition of more than 700 megawatts of
new generation capacity and the replacement of steam generators at our
Callaway nuclear plant. The 700 megawatts of new generation is expected to
be satisfied by 240 megawatts that were added by us in 2002 and the
proposed transfer at net book value (December 31, 2002 - approximately $260
million) to us of approximately 550 megawatts of generation assets from
Generating Company, which is subject to receipt of necessary regulatory
approvals and is expected to be completed in 2003.
o An annual reduction in our depreciation rates by $20 million, retroactive
to April 1, 2002, based on an updated analysis of asset values, service
lives and accumulated depreciation levels.
o A one-time credit of $40 million, which was accrued during the plan period.
The entire amount was paid to our Missouri retail electric customers in
2002 for the settlement of the final sharing period under the alternative
regulation plan that expired June 30, 2001.


Marketing Company - AmerenUE Power Supply Agreements

In order to satisfy our regulatory load requirements for 2001 and 2002, we
purchased, under a one-year contract 450 megawatts of capacity and energy (the
2001 Marketing Company - AmerenUE agreement) and 200 megawatts of capacity and
energy (the 2002 Marketing Company - AmerenUE agreement) from Marketing Company.
These agreements were entered into through a competitive bidding process and
reflected market-based rates. Generating Company supplied the power for these
agreements under its power supply agreement with Marketing Company.

The FERC accepted the 2001 Marketing Company - AmerenUE agreement as filed.
The 2002 Marketing Company - AmerenUE agreement was set for hearing to determine
that the contract terms were just and reasonable. On March 12, 2003, a
settlement between Marketing Company and the FERC Staff was approved by the FERC
effectively resolving all issues concering the 2002 Marketing Company - AmerenUE
agreement set for hearing. While the FERC order contains a standard refund
report requirement, no refunds are due under the settlement as approved.

In May 2001 and May 2002, the MoPSC filed complaints with SEC relating to
these agreements. While the complaints were pending, the MoPSC and AmerenUE
reached an agreement for resolving these disputes. The agreement requires us to
not enter into any new contracts to purchase wholesale electric energy from any
Ameren affiliate that is an exempt wholesale generator without first obtaining,
on a timely basis, the determinations required of the MoPSC that are specified
in Section 32(k) of PUHCA. However, this commitment did not prevent us from
completing the purchases contemplated by the 2001 and 2002 Marketing Company -
AmerenUE agreements and does not prevent us from making short term energy
purchases (less than 90 days) from an Ameren affiliate, without prior MoPSC
determination, to prevent or alleviate system emergencies. As part of this
agreement, the MoPSC has agreed to terminate its SEC complaints.

Illinois Electric

In 2002, all of our Illinois residential, commercial and industrial
customers had choice in electric suppliers.

As a provision of the legislation related to the restructuring of the
Illinois electric industry (the Illinois Law), a rate freeze is in effect
through January 1, 2007.

In October 2002, we and AmerenCIPS filed with the ICC a proposal to suspend
collection of transition charges associated with the Illinois Law for the period
commencing June 2003 until at least June 2005. The Illinois Law allows a utility
to collect transition charges from customers that elect to move from bundled
retail rates to market-based rates. Utilities have the right to collect
transition charges throughout the transition period that ends January 1, 2007.
The suspension of collection of transition charges is not expected to have a
material impact on either us or AmerenCIPS.

Under the Illinois Law, we were subject to a residential electric rate
decrease of up to 5% in 2002 to the extent our rates exceeded the Midwest
utility average. In 2002, 2001 and 2000, our Illinois electric rates were below
the Midwest utility average.


41

The Illinois Law also contains a provision requiring that one-half of
excess earnings from the Illinois jurisdiction for the years 1998 through 2006
be refunded to our Illinois customers. Excess earnings are defined as the
portion of the two-year average annual rate of return on common equity in excess
of 1.5% of the two-year average of an Index, as defined in the Illinois Law. The
Index is defined as the sum of the average for the twelve months ended September
30 of the average monthly yields of the 30-year U.S. Treasury bonds, plus
prescribed percentages ranging from 4% to 7%. Our Illinois average rate of
return on common equity for the two year average at December 31, 2002 was 13% as
compared to the average index of 12.6%. No refunds are expected to be required
for the period of April 1, 2002 through March 31, 2003. For the twelve months
ended December 31, 1999, we made excess earnings refunds of $2.1 million from
April 1, 2000 through March 31, 2001. For the twelve months ended December 31,
2000, we made excess earnings refunds of $1.5 million from April 1, 2001 through
May 31, 2002. These refunds were recorded as a reduction to Operating Revenues -
Electric.

Federal - Electric Transmission

Regional Transmission Organization

In December 1999, the FERC issued Order 2000, requiring all utilities,
subject to FERC jurisdiction, to state their intentions for joining a regional
transmission organization (RTO). RTOs are independent organizations that will
functionally control the transmission assets of utilities and are designed to
improve the wholesale power market. Beginning in January 2001, we and
AmerenCIPS, along with several other utilities, sought approval from the FERC to
participate in an RTO known as the Alliance RTO. We had previously been a member
of the Midwest Independent System Operator (Midwest ISO) and recorded a pretax
charge to earnings in 2000 of $17 million ($10 million, net of taxes) for an
exit fee and other costs when we left that organization. We believed that the
for-profit Alliance RTO business model was superior to the not-for-profit
Midwest ISO business model and provided us with a more equitable return on our
transmission assets.

In late 2001, the FERC issued an order that rejected the formation of the
Alliance RTO and ordered the Alliance RTO companies and the Midwest ISO to
discuss how the Alliance RTO business model could be accommodated within the
Midwest ISO. In April 2002, after the Alliance RTO and Midwest ISO failed to
reach an agreement, and after a series of filings by the two parties with the
FERC, the FERC issued a declaratory order setting forth the division of
responsibilities between the Midwest ISO and National Grid (the managing member
of the transmission company formed by the Alliance companies) and approved the
rate design and the revenue distribution methodology proposed by the Alliance
companies. However, the FERC denied a request by the Alliance companies and the
National Grid to purchase certain services from the Midwest ISO at incremental
cost rather than Midwest ISO's full tariff rates. The FERC also ordered the
Midwest ISO to return the exit fees paid by us and AmerenCIPS to leave the
Midwest ISO, provided we and AmerenCIPS return to the Midwest ISO and agree to
pay our proportional share of the startup and ongoing operational expenses of
the Midwest ISO. Moreover, the FERC required the Alliance companies to select
the RTO in which they will participate within thirty days of the order.

Following the April 2002 FERC order, we and AmerenCIPS have made filings
with the FERC indicating that we would return to the Midwest ISO through a new
independent transmission company, GridAmerica LLC, that was agreed to be formed
by us and AmerenCIPS, along with subsidiaries of FirstEnergy Corporation and
NiSource Inc. Upon receipt of final FERC approval of the definitive agreements
establishing GridAmerica, a subsidiary of National Grid will serve as the
managing member of GridAmerica and will manage the transmission assets of the
three companies and participate in the Midwest ISO on behalf of GridAmerica.
Other Alliance RTO companies announced their intentions to join the PJM
Interconnection LLC (PJM) RTO. On July 25, 2002, we and AmerenCIPS filed a
motion with the FERC requesting that it condition the approval of the choices of
other Illinois utilities to join the PJM RTO on Midwest ISO and PJM entering
into an agreement addressing important reliability and rate-barrier issues. On
July 31, 2002, the FERC issued an order accepting the formation of GridAmerica
as an independent transmission company under the Midwest ISO subject to further
compliance filings ordered by the FERC. The FERC also issued an order accepting
the elections made by the other Illinois utilities to join the PJM RTO on the
condition PJM and Midwest ISO immediately begin a process to address the
reliability and rate-barrier issues raised by us and other market participants
in previous filings.

The compliance filing to facilitate the formation and operation of
GridAmerica as an independent transmission company within the Midwest ISO, as
contemplated in the July 31, 2002 order of the FERC, was conditionally accepted
by the FERC in an order issued December 19, 2002. In the order, the FERC
approved the return of the $13 million exit fee paid by us to leave the Midwest
ISO with interest once GridAmerica becomes operational. The FERC also approved,
subject to further filings, reimbursement of $36 million to the GridAmerica
Companies for expenses incurred to form the Alliance RTO. GridAmerica is
scheduled to become operational in Spring 2003. Our

42


participation in GridAmerica remains subject to MoPSC approval. An order from
the MoPSC is expected during the third quarter of 2003.

Until the reliability and rate-barrier issues are resolved as ordered by
the FERC, and the tariffs and other material terms of our participation in
GridAmerica, and GridAmerica's participation in the Midwest ISO, are finalized
and approved by the FERC, we are unable to predict the impact that on-going RTO
developments will have on our financial position, results of operations or
liquidity.

Standard Market Design Notice of Proposed Rulemaking (NOPR)

On July 31, 2002, the FERC issued a Standard Market Design NOPR. The NOPR
proposes a number of changes to the way the current wholesale transmission
service and energy markets are operated. Specifically, the NOPR calls for all
jurisdictional transmission facilities to be placed under the control of an
independent transmission provider (similar to an RTO), proposes a new
transmission service tariff that provides a single form of transmission service
for all users of the transmission system including bundled retail load, and
proposes a new energy market and congestion management system that uses
locational marginal pricing as its basis. On November 15, 2002, we filed our
initial comments on the NOPR with the FERC expressing our concern with the
potential impact of the proposed rules in their current form on the cost and
reliability of service to retail customers. We also proposed that certain
modifications be made to the proposed rules in order to protect transmission
owners from the possibility of trapped transmission costs that might not be
recoverable from ratepayers as a result of inconsistent regulatory policies. We
filed additional comments on the remaining sections of the NOPR during the first
quarter of 2003. Until the FERC issues a final rule, we are unable to predict
the ultimate impact on our future financial position, results of operations or
liquidity.

Illinois Gas

In November 2002, we filed a request with the ICC to increase annual rates
for natural gas services by approximately $4 million. The ICC has until October
2003 to render a decision on this request.


NOTE 3 - Related Party Transactions

We have transactions in the normal course of business with our parent,
Ameren, and its other subsidiaries. These transactions are primarily comprised
of power purchases and sales, as well as other services received or rendered.
Intercompany power purchases from joint dispatch and other agreements were
approximately $108 million for 2002 (2001 - $134 million; 2000 - $98 million).
Intercompany power sales totaled $84 million for 2002 (2001 - $82 million; 2000
- - $80 million).

Support services provided by our affiliates, Ameren Services and
AmerenEnergy, including wages, employee benefits and professional services are
based on actual costs incurred. For the year ended December 31, 2002, support
services provided by Ameren Services and AmerenEnergy included in Operating
Expenses - Other Operations and Maintenance totaled $196 million (2001 - $170
million; 2000 - $154 million).

As of December 31, 2002, intercompany receivables included in Miscellaneous
Accounts and Notes Receivable were approximately $25 million (2001 - $38
million). As of December 31, 2002, intercompany payables included in Accounts
and Wages Payable totaled approximately $103 million (2001 - $70 million).

We have the ability to borrow from Ameren and AmerenCIPS through a utility
money pool agreement. Ameren Services administers the utility money pool and
tracks internal and external funds separately. Internal funds are surplus funds
contributed to the utility money pool from participants. The primary source of
external funds for the utility money pool at December 31, 2002 was our
commercial paper program. Through the utility money pool we can access committed
credit facilities at Ameren and AmerenCIPS which totaled $615 million at
December 31, 2002. These facilities are in addition to our own $80 million in
committed credit facilities. The total amount available to us at any given time
from the utility money pool is reduced by the amount of borrowings by our
affiliates, but increased to the extent Ameren, AmerenCIPS or Ameren Services
have surplus funds and the availability of other external borrowing sources.
Surplus funds providing additional liquidity available to us through the utility
money pool totaled $628 million at December 31, 2002, of which approximately
$500 million was used to acquire CILCORP and Medina Valley in early 2003. The
availability of funds is also determined by funding requirement limits
established by the PUHCA. We, along with AmerenCIPS and Ameren Services, rely on
the utility money pool to coordinate and provide for certain short-term cash and
working capital requirements. Borrowers receiving a loan under the utility money
pool agreement must repay the principal amount of such loan, together with
accrued interest. Interest is calculated at varying rates of interest depending
on the composition of

43



internal and external funds in the utility money pool. For the year ended
December 31, 2002, the average interest rate for the utility money pool was
1.68% (2001 - 3.95%). Based on outstanding commercial paper as of December 31,
2002, we had the ability to borrow up to $445 million through the utility money
pool, which was in addition to amounts available through cash balances at
Ameren. At December 31, 2002, we had outstanding intercompany payables of $15
million, sourced by internal funds through the utility money pool. At December
31, 2001, we had outstanding intercompany receivables of $84 million through the
utility money pool.

Subject to the receipt of regulatory approval, which is being pursued,
AmerenCILCO will participate in Ameren's utility money pool arrangement. At
December 31, 2002, CILCO had committed credit facilities, expiring at various
dates during 2003, totaling $60 million.

NOTE 4 - Derivative Financial Instruments

We utilize derivatives principally to manage the risk of changes in market
prices for natural gas, fuel, electricity and emission credits. Price
fluctuations in natural gas, fuel and electricity cause:

o an unrealized appreciation or depreciation in the value of our firm
commitments to purchase or sell when purchase or sales prices under the
firm commitment are compared with current commodity prices;
o market values of fuel and natural gas inventories or purchased power to
differ from the cost of those commodities in inventory or under the firm
commitment; and
o actual cash outlays for the purchase of these commodities, in certain
circumstances, to differ from anticipated cash outlays.

The derivatives that we use to hedge these risks are dictated by risk
management policies and include forward contracts, futures contracts, options
and swaps. We continually assess our supply and delivery commitment positions
against forward market prices and internal forecasts of forward prices. We
actively manage our exposure to power price risk through our power risk
management program carried out under our risk management guidelines to modify
our exposure to market, credit and operational risk by entering into various
offsetting transactions. In general, we believe these transactions serve to
reduce price risk for us.

In addition, we may purchase additional power, again within risk management
guidelines, in anticipation of power requirements and future price changes.
Certain derivative contracts we enter into on a regular basis as part of our
power risk management program do not qualify for hedge accounting or the normal
purchase and sale exceptions under SFAS 133. Accordingly, these contracts are
recorded at fair value with changes in the fair value charged or credited to the
income statement in the period in which the change occurred. Contracts we enter
into as part of our power risk management program may be settled by either
physical delivery or net settled with the counterparty. See also Note 1 -
Summary of Significant Accounting Policies for further information.

As of December 31, 2002, we recorded the fair value of derivative financial
instrument assets of $7 million in Other Assets and the fair value of derivative
financial instrument liabilities of $1 million in Other Deferred Credits and
Liabilities.


Cash Flow Hedges

We routinely enter into forward purchase and sales contracts for
electricity based on forecasted levels of economic generation and customer
requirements. The relative balance between customer requirements and economic
generation varies throughout the year. The contracts typically cover a period of
twelve months or less. The purpose of these contracts is to hedge against
possible price fluctuations in the spot market for the period covered under the
contracts. We formally document all relationships between hedging instruments
and hedged items, as well as our risk management objective and strategy for
undertaking various hedge transactions. The mark-to-market value of cash flow
hedges will continue to fluctuate with changes in market prices up to contract
expiration.

The pretax net loss on power forward derivative instruments, which
represented the impact of discontinued cash flow hedges, the ineffective portion
of cash flow hedges, as well as the reversal of amounts previously recorded in
OCI due to transactions going to delivery or settlement, was approximately $2
million for the year ended December 31, 2002 (2001 - $10 million pretax net
gain).

44



As of December 31, 2002, we had hedged a portion of the electricity price
exposure for the upcoming twelve-month period. The mark-to-market value
accumulated in OCI for the effective portion of hedges of electricity price
exposure was a net gain of approximately $0.6 million ($0.4 million, net of
taxes).

As of December 31, 2002, a gain of approximately $0.5 million ($0.3
million, net of taxes) associated with natural gas swaps was included in OCI.
The swaps were a partial hedge of our index priced, baseload gas supply for the
period of December 2002 through March 2003. The swaps effectively fix the price
on a portion of our gas supply for that time period.

We also held three call options for coal with two suppliers. These options
to purchase coal expire October 2003, July 2004 and July 2005. As of December
31, 2002, a mark-to-market gain of approximately $6 million ($4 million, net of
taxes) associated with these options was included in OCI. The final value of the
options will be recognized as a reduction in fuel costs as the hedged coal is
burned.

Other Derivatives

We enter into option transactions to manage our positions in sulfur dioxide
allowances, coal, heating oil and electricity. Most of these transactions are
treated as non-hedge transactions under SFAS 133. The net change in the market
value of sulfur dioxide, coal, heating oil and electricity options is recorded
as Other Income and Deductions in the income statement. The net change in the
market values of sulfur dioxide, coal, heating oil, and electricity options was
a gain of $5 million ($3 million net of taxes) for the year ended December 31,
2002 (2001 - $3 million loss or $2 million, net of taxes).


NOTE 5 - Property and Plant, Net

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


NOTE 6 - Nuclear Fuel Lease

We have a lease agreement, expiring on August 31, 2031, that provides for
the financing of a portion of our nuclear fuel that is being processed for use
or being consumed in our Callaway nuclear plant. The lease agreement has
variable interest rates based on short-term commercial paper interest rates. At
December 31, 2002, the maximum amount that could be financed under the agreement
was $120 million, of which $113 million was utilized. The lessor, Gateway Fuel
Company, maintains a $120 million committed credit facility which supports the
financing of fuel under the lease. We consider available lease capacity, future
purchase commitments and upcoming in-service fuel requirements when determining
whether to utilize leased nuclear fuel. We are not required to pay the lessor,
an unrelated third party, unless nuclear fuel is removed from the lease,
consumed at our nuclear plant or the lease is terminated. Pursuant to the terms
of the lease, we assign to the lessor certain contracts for purchase of nuclear
fuel. The lessor obtains, through the issuance of commercial paper or from
direct loans under a committed revolving credit agreement from commercial banks,
the necessary funds to purchase the fuel and make interest payments when due.

We are obligated to reimburse the lessor for expenditures for nuclear fuel,
interest and related costs under the lease. As any leased nuclear fuel is
consumed at our Callaway nuclear plant, obligations under this lease become due.
No leased nuclear fuel was consumed in 2001. Therefore, no reimbursements for
amounts consumed under the lease occurred in 2001. Leased nuclear fuel
consumption re-commenced in the fourth quarter of 2002. The

45



corresponding reimbursement will occur in the first quarter of 2003. We
reimbursed $13 million during 2000 for amounts consumed under the lease.

We have capitalized the cost of the leased nuclear fuel incurred by the
lessor, plus certain interest costs, and have recorded the related lease
obligation. Total interest charges under the lease were $2 million in 2002, $4
million in 2001, and $8 million in 2000. Interest charges for these years were
based on average interest rates of approximately 2% for 2002, 5% for 2001 and 7%
for 2000. Interest charges of $2 million in 2002, $4 million in 2001, and $6
million in 2000 were capitalized.


NOTE 7 - Preferred Stock

Outstanding preferred stock is entitled to cumulative dividends and is
redeemable, at the option of the issuer, at the prices shown in the following

(a) Generally, for the issuance of additional preferred stock, earnings coverage
of at least two and one-half times the annual dividend on preferred stock
outstanding and to be issued is required under our Articles of Incorporation.
The ability to issue such securities in the future will depend on coverage at
that time. At December 31, 2002, we had and expect to continue to have adequate
coverage ratios for anticipated requirements.
(b) Beginning February 15, 2003, declining to $100 per share in 2012.
(c) In the event of voluntary liquidation, $105.50.



NOTE 8 - Short-Term Borrowings

Our short-term borrowings consist of commercial paper and bank loans
(maturities generally within 1-45 days) and may also include utility money pool
advances. At December 31, 2002, we had $250 million (2001 - $186 million) of
commercial paper outstanding and $15 million borrowed under the utility money
pool. The weighted average interest rate on short-term borrowings outstanding at
December 31, 2002 was 1.4% (2001 - 1.8%).

At December 31, 2002, Ameren and its subsidiaries had committed credit
facilities, expiring at various dates between 2003 and 2005, totaling $695
million, excluding EEI facilities of $45 million and our nuclear fuel lease
facilities of $120 million. This amount includes $80 million of our committed
credit facilities and $615 million of committed credit facilities at Ameren and
AmerenCIPS. We access these facilities through Ameren's utility money pool
arrangement. AmerenCIPS and Ameren Services may also borrow under this
arrangement. These committed credit facilities are used to support our
commercial paper program under which $250 million was outstanding at December
31, 2002. Based on commercial paper outstanding at December 31, 2002, $445
million was unused and available under these committed credit facilities and
available to us through the utility money pool.

Subject to the receipt of regulatory approval, which is being pursued,
AmerenCILCO will participate in Ameren's utility money pool arrangement. At
December 31, 2002, CILCO had committed credit facilities, expiring at various
dates during 2003, totaling $60 million. See Note 3 - Related Party Transactions
for further information about the utility money pool.


46



EEI also has two bank credit agreements totaling $45 million that expire in
2003. At December 31, 2002, $27 million was unused and available under these
committed credit facilities.

Certain of our and Ameren's financing arrangements contain provisions
which, among other things, limit our ability to encumber or sell assets, merge
with other entities or permit to exist restrictions on's credit agreements
contain a covenant which requires Ameren, AmerenCIPS and us to maintain a ratio
of total indebtedness to total capital of 60% or less. One of our credit
agreements contains a similar provision which restricts the ratio to 65% or
less. Certain of these arrangements contain material adverse change clauses
which could limit our ability to borrow under such facilities or to access
borrowing under these facilities through the utility money pool. In addition,
Ameren's credit agreements contain indebtedness cross default provisions which
could trigger a default under these facilities in the event any subsidiary of
Ameren (subject to definition in the underlying credit agreements) other than
certain project finance subsidiaries defaults in indebtedness in excess of $50
million. None of our, AmerenCIPS' or Ameren's financing arrangements contains
credit rating triggers, with the exception of certain ratings triggers within
AmerenCILCO's financing arrangements.

Most of Ameren's committed credit facilities include provisions related to
the funded status of Ameren's pension plan. These provisions either require
Ameren to meet minimum ERISA funding requirements or limit the unfunded
liability status of the plan. Under the most restrictive of these provisions
impacting Ameren facilities totaling $400 million, an event of default will
result if the unfunded liability status (as defined in the underlying credit
agreements) of Ameren's pension plan exceeds $300 million in the aggregate.
Based on the most recent valuation report available to Ameren at December 31,
2002, which was based on January 2002 asset and liability valuations, the
unfunded liability status (as defined) was $31 million. While an updated
valuation report will not be available until the second half of 2003, Ameren
believes that the unfunded liability status of our pension plans (as defined)
could exceed $300 million based on the investment performance of the pension
plan assets and interest rate changes since January 1, 2002. As a result, Ameren
may need to renegotiate the facility provisions, terminate or replace the
affected facilities, or fund any unfunded liability shortfall. Should Ameren
elect to terminate these facilities, we believe we would otherwise have
sufficient liquidity to manage our short-term funding requirements.

At December 31, 2002, Ameren and its subsidiaries, including us, were in
compliance with all such provisions.

(a) At December 31, 2002, a majority of property and plant was mortgaged under,
and subject to lien of, the indenture pursuant to which the bonds were
issued. Our first mortgage bond indenture contains provisions that restrict
the issuance of additional bonds. These provisions restrict future first
mortgage bond issuance to 60% of unused net bondable property and
previously retired bonds. In addition, net earnings must be at least twice
that of first mortgage bond interest to be able to issue bonds under the
indenture. At December 31, 2002, we were in compliance with all such
provisions.
(b) Environmental Improvement Series backed by first mortgage bonds.
(c) Interest rates, and the periods during which such rates apply, vary
depending on our selection of certain defined rate modes. The average
interest rates for the year 2002 were as follows: `
1991 Series 1.64%
1992 Series 1.60%
1998 Series A 1.53%
1998 Series B 1.53%

2000 Series A 1.56%
2000 Series B 1.52%
2000 Series C 1.56%
(d) During the terms of the debentures, we may, under certain circumstances,
defer the payment of interest for up to five years. Upon election to defer
interest payments, dividend payments to Ameren are prohibited.

The following table summarizes the maturities of long-term debt at December 31,
2002:

In July 2002, Ameren entered into new committed credit agreements for $400
million in revolving credit facilities to be used for general corporate
purposes, including support of commercial paper programs. We may access these
new credit facilities through the utility money pool. The $400 million in new
facilities includes a $270 million 364-day revolving credit facility and a $130
million 3-year revolving credit facility. The 3-year facility has a $50 million
sub-limit for the issuance of letters of credit. These new credit facilities
replaced our former $300 million revolving credit facility.

In August 2002, a shelf registration statement filed by us with the SEC on
Form S-3 was declared effective. This statement authorized the offering from
time to time of up to $750 million of various forms of long-term debt and trust
preferred securities to refinance existing debt and preferred stock and for
general corporate purposes, including the repayment of short-term debt incurred
to finance construction expenditures and other working capital needs.

In August 2002, we issued, pursuant to the shelf registration statement,
$173 million of 5.25% Senior Secured Notes due September 1, 2012. Interest is
payable semi-annually on March 1 and September 1 of each year, beginning March
1, 2003. Net proceeds were $172 million, after debt discount and fees. These
senior secured notes are secured by a related series of our first mortgage bonds
until the release date as described in the senior secured note indenture.
Proceeds were used to redeem, in September 2002, our $125 million principal
amount 8.75% first mortgage bonds due December 1, 2021 at a 4.38% premium and
our $42 million $1.735 series preferred stock at par.

In December 2002, upon receipt of all the necessary federal and state
regulatory approvals, we, pursuant to Missouri economic development statutes,
conveyed most of our Peno Creek combustion turbine generating facility to the
City of Bowling Green, Missouri in exchange for the issuance by the City of a
taxable industrial development revenue bond in the amount of $103.4 million.
Concurrently, the City leased back the facility to us for a term of 20 years.
The lease term is the same as the final maturity of the bond we purchased.
Although the lease is a capital lease, no capital was raised in the transaction.
We are responsible for making rental payments under the lease in an amount
sufficient to pay the debt service of the bond. The City's ownership of the
facility during the term of the bond and the lease is expected to result in
property tax savings to us. Under the terms of the lease, we retain all
operation and maintenance responsibilities of the facility and ownership of the
facility is returned to us at the expiration of the lease.

We expect to fund maturities of long-term debt and contractual obligations
through a combination of cash flow from operations and external financing.

At December 31, 2002, neither Ameren, nor any of its subsidiaries,
including us, had any off-balance sheet financing arrangements, other than
operating leases entered into in the ordinary course of business. We do not
expect to engage in any significant off-balance sheet financing arrangements in
the near future.

Amortization of debt issuance costs and any premium or discounts for the
year ended December 31, 2002 of $4 million (2001 - $3 million; 2000 - $3
million) were included in interest expense in the income statement.


NOTE 10 - Voluntary Retirement and Other Restructuring Charges

Voluntary retirement and other restructuring charges were $65 million in
2002 or $41 million, net of taxes.

In December 2002, approximately 550 Ameren employees, which includes
approximately 230 of our employees and additional employees providing support
functions to us through Ameren Services, accepted a voluntary retirement program
that was offered to approximately 1,000 of Ameren's 7,400 employees. Eligible
employees had to be age 50 or over, regular, full-time employees and have at
least 10 years of service with Ameren. While we expect to realize significant
long-term savings as a result of this program, we incurred a charge of $51
million ($32 million, net of taxes) in December 2002 related to the voluntary
retirement program. These costs consisted primarily of special termination
benefits associated with Ameren's pension and post-retirement benefit plans.

In December 2002, we also retired 343 megawatts of rate-regulated capacity
at our Venice, Illinois plant. This capacity reduction and related severance
resulted in a charge of $14 million ($9 million, net of taxes) in December 2002.

NOTE 11 - Miscellaneous, Net

Miscellaneous, net for the years ended December 31, 2002, 2001 and 2000
consisted of the following:

NOTE 12 - Income Taxes

Total income tax expense for 2002 resulted in an effective tax rate of 36%
on earnings before income taxes (38% in 2001 and 39% in 2000).

Principal reasons such rates differ from the statutory federal rate for the
years ended December 31, 2002, 2001 and 2000 were as follows:

- --------------------------------------------------------------------------------
2002 2001 2000
- --------------------------------------------------------------------------------
Statutory federal income tax rate: 35% 35% 35%
Increases (decreases) from:

State tax 3 3 3
Other (4) (2) (1)
- --------------------------------------------------------------------------------
Effective income tax rate 36% 38% 39%
- --------------------------------------------------------------------------------

Components of income tax expense for the years ended December 31, 2002,
2001 and 2000 were as follows:

- --------------------------------------------------------------------------------
2002 2001 2000
- --------------------------------------------------------------------------------
Taxes currently payable (principally federal):
Included in operating expenses $174 $219 $231
Included in other income (3) 2 (3)

Deferred investment tax credits, amortization:
Included in operating expenses (6) (6) (5)
- --------------------------------------------------------------------------------
Total income tax expense $193 $230 $224
- --------------------------------------------------------------------------------

In accordance with SFAS No. 109, "Accounting for Income Taxes," a
regulatory asset, representing the probable recovery from customers of future
income taxes, which is expected to occur when temporary differences reverse, was
recorded along with a corresponding deferred tax liability. Also, a regulatory
liability, recognizing the lower expected revenue resulting from reduced income
taxes associated with amortizing accumulated deferred investment tax credits,
was recorded. Investment tax credits have been deferred and will continue to be
credited to income over the lives of the related property.

We adjust our deferred tax liabilities for changes enacted in tax laws or
rates. Recognizing that regulators will probably reduce future revenues for
deferred tax liabilities initially recorded at rates in excess of the current
statutory rate, reductions in the deferred tax liability were credited to the
regulatory liability.

Temporary differences gave rise to the following deferred tax assets and
deferred tax liabilities at December 31, 2002 and 2001:

- --------------------------------------------------------------------------------
2002 2001
- --------------------------------------------------------------------------------
Accumulated deferred income taxes:

NOTE 13 - Retirement Benefits

Pension

Ameren has defined benefit retirement plans covering substantially all of
our employees. Benefits are based on the employees' years of service and
compensation. Ameren's plans are funded in compliance with income tax
regulations and federal funding requirements. AmerenUE, along with other
subsidiaries of Ameren, is a participant in Ameren's plans and is responsible
for its proportional share of the costs. Our share of the pension costs for 2002
was $12 million (2001 - $3 million; 2000 - $2 million) of which approximately
16% (2001 - 16%; 2000 - 20%) was charged to construction accounts.

Ameren made cash contributions totaling $31 million to Ameren's defined
benefit retirement plan during 2002. Our share of the cash contribution was
approximately $23 million, which includes our portion related to Ameren
Services. At December 31, 2002, Ameren recorded a minimum pension liability of
$102 million, net of taxes, which resulted in a charge to OCI and a reduction to
stockholders' equity. Our share of the minimum pension liability was
approximately $62 million, net of taxes. Based on the performance of plan assets
through December 31, 2002, Ameren expects to be required under the Employee
Retirement Income Security Act of 1974 to fund annually $150 million to $175
million in 2005, 2006 and 2007 in order to maintain minimum funding levels. In
addition, Ameren estimates the pension funding for CILCORP to be less than $1
million in 2003 and approximately $5 million in 2004. We expect our share of the
annual funding in 2005, 2006 and 2007 to be between $110 million to $128
million, which includes our share related to employees of Ameren Services. These
amounts are estimates and may change based on actual stock market performance,
changes in interest rates and any changes in government regulations. At December
31, 2002, Ameren's Net Benefit Obligation was $1,587 million and its Fair Value
of Plan Assets was $1,059 million.

Ameren's assumptions for actuarial present value of projected benefit
obligations during 2002, 2001 and 2000 were as follows:

- --------------------------------------------------------------------------------
2002 2001 2000
- --------------------------------------------------------------------------------
Discount rate at measurement date 6.75% 7.25% 7.50%
Expected return on plan assets 8.50% 8.50% 8.50%
Increase in future compensation 3.75% 4.25% 4.50%
- --------------------------------------------------------------------------------

Post-retirement

Ameren's funding policy for post-retirement benefits is to annually fund
the Voluntary Employee Beneficiary Association trusts (VEBA) with the lesser of
the net periodic cost or the amount deductible for federal income tax purposes.
We, along with other subsidiaries of Ameren, are a participant in the VEBA,
which covers substantially all of our employees, and are responsible for our
proportional share of the costs. Our share of the postretirement benefit costs
for 2002 was $57 million (2001 - $51 million; 2000 - $46 million) of which
approximately 16% (2001 - 18%; 2000 - 17%) were charged to construction
accounts. The MoPSC and the ICC allow the recovery of postretirement benefit
costs in rates to the extent that such costs are funded.

Ameren's assumptions for the post-retirement benefit plan obligation
measurements for the years ended December 31, 2002, 2001 and 2000 were as
follows:

- --------------------------------------------------------------------------------
2002 2001 2000
- --------------------------------------------------------------------------------
Discount rate at measurement date 6.75% 7.25% 7.50%
Expected return on plan assets 8.50% 8.50% 8.50%
Medical cost trend rate (initial) 10.00% 5.25% 5.00%
Medical cost trend rate (ultimate) 5.25% 5.25% 5.00%
- --------------------------------------------------------------------------------

NOTE 14 - Commitments and Contingencies

As a result of issues generated in the course of daily business, we are
involved in legal, tax and regulatory proceedings before various courts,
regulatory commissions and governmental agencies, some of which involve
substantial amounts of money. We believe that the final disposition of these
proceedings, except as otherwise disclosed in this report and in the Notes to
our Financial Statements, will not have an adverse material effect on our
financial position, results of operations or liquidity.

51


Capital Expenditures

We estimate our capital expenditures over the next five years will be
approximately $2.0 billion to $2.5 billion, including allowance for funds used
during construction and capitalized interest. This estimate includes capital
expenditures for the construction and acquisition from an affiliate of
combustion turbine generating facilities and the replacement of steam generators
at our Callaway nuclear plant. In addition, this estimate includes capital
expenditures for transmission, distribution and other generation related
activities, as well as for compliance with new NOx (nitrogen oxide) control
regulations, as discussed later in this Note. Commitments of $2.25 billion to
$2.75 billion were agreed upon in relation to our recent Missouri electric rate
case settlement and to meet future rate-regulated generating capacity needs from
January 1, 2002 through June 30, 2006.

Our capital program is subject to periodic review and revision, and actual
capital costs may vary from the above estimate because of numerous factors.
These factors include changes in business conditions, acquisition of additional
generating assets, revised load growth estimates, changes in environmental
regulations, changes in our existing nuclear plant to meet new regulatory
requirements, increasing costs of labor, equipment and materials, and cost of
capital.

Subject to the receipt of required regulatory agency approvals, we intend
to purchase at net book value approximately 550 megawatts (approximately $260
million) of generating capacity from our non rate-regulated affiliate,
Generating Company, to comply with our recent Missouri electric rate case
settlement and to meet future rate-regulated generating capacity needs. In
addition, we intend to replace our retired 343 megawatts of rate-regulated
capacity at our Venice, Illinois plant (see Note 10 - Voluntary Retirement and
Other Restructuring Charges for further information) with the addition of 117
megawatts of capacity by 2005 and at least 330 megawatts of capacity by 2006 at
Venice. Total costs expected to be incurred for these units approximate $175
million of which approximately $100 million was committed as of December 31,
2002.

Fuel Purchase Commitments

To supply a portion of the fuel requirements of our generating plants, we
have entered into various long-term commitments for the procurement of fossil
and nuclear fuel. In addition, we have entered into various long-term
commitments for the purchase of electricity. Total estimated fuel purchase
commitments at December 31, 2002 were as follows:

- --------------------------------------------------------------------------------
Coal Gas Nuclear Electric Capacity
- --------------------------------------------------------------------------------
2003 $332 $30 $9 $22
2004 288 20 1 22
2005 151 19 9 22
2006 66 7 9 22
2007 24 1 1 22
Thereafter 70 - 20 22
- --------------------------------------------------------------------------------
Total $931 $77 $49 $132
- --------------------------------------------------------------------------------

Nuclear Plant Insurance Coverage

Our insurance coverage at our Callaway nuclear plant at December 31, 2002
was as follows:
- --------------------------------------------------------------------------------
Maximum
Assessments
Type and Source of Coverage Maximum For Single
Coverages Incidents
- --------------------------------------------------------------------------------
Public Liability:
American Nuclear Insurers $ 200 $ -
Pool Participation 9,250 88(a)

- --------------------------------------------------------------------------------
Property Damage:
Nuclear Electric Insurance Ltd. $2,750(d) $ 21
- --------------------------------------------------------------------------------
Replacement Power:
Nuclear Electric Insurance Ltd. $ 490(e) $ 7
- --------------------------------------------------------------------------------
(a) Retrospective premium under the Price-Anderson liability provisions of the
Atomic Energy Act of 1954, as amended (Price-Anderson). This is subject to
retrospective assessment with respect to loss from an incident at any U.S.
reactor, payable at $10 million per year. Price-Anderson expired in August
2002 and renewal legislation is pending before Congress. Until
Price-Anderson is extended, its provisions continue to apply to existing
nuclear plants.
(b) Limit of liability for each incident under Price-Anderson.
(c) Industry limit for potential liability from workers claiming exposure to
the hazard of nuclear radiation.
(d) Includes premature decommissioning costs.
(e) Weekly indemnity of $3.5 million for 52 weeks which commences after the
first 8 weeks of an outage, plus $2.8 million per week for 110 weeks
thereafter.
- --------------------------------------------------------------------------------

Price-Anderson limits the liability for claims from an incident involving
any licensed U.S. nuclear facility. The limit is based on the number of licensed
reactors and is adjusted at least every five years based on the Consumer Price
Index. Utilities owning a nuclear reactor cover this exposure through a
combination of private insurance and mandatory participation in a financial
protection pool, as established by Price-Anderson.

If losses from a nuclear incident at Callaway exceed the limits of, or are
not subject to, insurance, or if coverage is not available, we will self-insure
the risk. Although we have no reason to anticipate a serious nuclear incident,
if one did occur, it could have a material, but indeterminable, adverse effect
on our financial position, results of operations or liquidity.

Leases

The following table summarizes our lease obligations at December 31, 2002:

- --------------------------------------------------------------------------------
Total Less than 1 - 3 4 - 5 After 5
1 year years years years
- --------------------------------------------------------------------------------
Capital leases (a) $ 216 $ 31 $ 70 $ 30 $ 85

- --------------------------------------------------------------------------------
Total lease obligations $ 346 $ 41 $ 89 $ 48 $ 168
- --------------------------------------------------------------------------------
(a) See Note 6 - Nuclear Fuel Lease and Note 9 - Long-Term Debt and
Capitalization for further discussion.
(b) Amounts related to certain real estate leases and railroad licenses have
indefinite payment periods. The amounts for these items are included in the
less than 1 year, 1-3 years and 4-5 years. Amounts for after 5 years are
not included in the total amount due to the indefinite periods. The
estimated obligation for after 5 years is $1 million annually for both the
real estate leases and the railroad licenses.

We lease various facilities, office equipment, plant equipment and railcars
under operating leases. We also have capital leases relating to nuclear fuel
and combustion turbine generators As of December 31, 2002, rental expense,
included in other operations expenses, totaled approximately $24 million (2001 -
$19 million; 2000 - $23 million). See Note 6 - Nuclear Fuel Lease and Note 9 -
Long-Term Debt and Capitalization for further information.


53



Environmental Matters

We are subject to various environmental regulations by federal, state, and
local authorities. From the beginning phases of siting and development, to the
ongoing operation of existing or new electric generating, transmission, and
distribution facilities, our activities involve compliance with diverse laws and
regulations that address emissions and impacts to air and water, special,
protected, and cultural resources (such as wetlands, endangered species, and
archeological/historical resources), chemical and waste handling, and noise
impacts. Our activities require complex and often lengthy processes to obtain
approvals, permits, or licenses for new, existing, or modified facilities.
Additionally, the use and handling of various chemicals or hazardous materials
(including wastes) requires preparation of release prevention plans and
emergency response procedures. As new laws or regulations are promulgated, we
assess their applicability and implement the necessary modifications to our
facilities or their operations, as required. The more significant matters are
discussed below.

Clean Air Act

The Clean Air Act affects both existing generating facilities and new
projects. The Clean Air Act and many state laws require significant reductions
in SO2 (sulfur dioxide) and NOx emissions that result from burning fossil fuels.
The Clean Air Act also contains other provisions that could materially affect
some of our projects. Various provisions require permits, inspections, or
installation of additional pollution control technology or may require the
purchase of emission allowances. Certain of these provisions are described in
more detail below.

The Clean Air Act creates a marketable commodity called an SO2 "allowance."
All generating facilities over 25 megawatts that emit SO2 must obtain allowances
in order to operate after 1999. Each allowance gives the owner the right to emit
one ton of SO2. All existing facilities have been allocated allowances based on
a facility's past production and the statutory emission reduction goals. If
additional allowances are needed for new generating facilities, they can be
purchased from facilities having excess allowances or from SO2 allowance banks.
Our generating facilities comply with the SO2 allowance caps through the
purchase of allowances or use of low sulfur fuels. The additional costs of
obtaining allowances needed for future generation projects should not materially
affect our ability to build, acquire, and operate them.

The U.S. Environmental Protection Agency (EPA) issued a rule in October
1988 requiring 22 Eastern states and the District of Columbia to reduce
emissions of NOx in order to reduce ozone in the Eastern United States. Among
other things, the EPA's rule establishes an ozone season, which runs from May
through September, and a NOx emission budget for each state, including Illinois.
The EPA rule requires states to implement controls sufficient to meet their NOx
budget by May 31, 2004.

In February 2002, the EPA proposed similar rules for Missouri, where the
majority of our facilities are located. Assuming the Missouri rules are
ultimately finalized, we estimate approximately $170 million to comply with
these rules for NOx control on our generating system by 2006. This estimate
includes the assumption that the regulations will require the installation of
Selective Catalytic Reduction technology on some of our units, as well as
additional controls.

Under the Missouri regulatory program, we have applied for Early Reduction
NOx credits which would allow us to manage compliance strategies by either
purchasing NOx control equipment or utilizing credits. We are eligible for such
credits due to the current low NOx emission rates achieved on some of our
boilers due to past NOx control efforts.

On December 31, 2002, the EPA published in the Federal Register revisions
to the New Source Review (NSR) programs under the Clean Air Act, including
changes to the routine maintenance, repair and replacement exclusions. Various
Northeastern states have filed a petition with the United States District Court
for the District of Columbia challenging the legality of the revisions to the
NSR programs. It is likely that various industries and environmental groups will
seek to intervene in that challenge. At this time, we are unable to predict the
impact of this challenge on our future financial position, results of operation
or liquidity.

54


National Ambient Air Quality Standards

In July 1997, the EPA issued regulations revising the National Ambient Air
Quality Standards for ozone and particulate matter. The standards were
challenged by industry and some states, and arguments were eventually heard by
the U.S. Supreme Court. In February 2001, the Supreme Court upheld the standards
in large part, but remanded a number of significant implementation issues back
to the EPA for resolution. The EPA is currently working on a new rulemaking to
address the issues raised by the Supreme Court. New ambient standards may
require significant additional reductions in SO2 and NOx emissions from our
power plants by 2008. At this time, we are unable to predict the ultimate impact
of these revised air quality standards on our future financial condition,
results of operations or liquidity.

Mercury and Regional Haze Regulations

In December 1999, the EPA issued a decision to regulate mercury emissions
from coal-fired power plants by 2008. The EPA is scheduled to propose
regulations by 2004. These regulations have the potential to add significant
capital and/or operating costs to our generating systems after 2005. The EPA is
scheduled to issue Best Available Retrofit Technology (BART) guidelines to
address visibility impairment (so called "Regional Haze") across the United
States from sources of air pollution, including coal-fired power plants. The
guidelines are to be used by states to mandate pollution control measures for
SO2 and NOx emissions. These rules could also add significant pollution control
costs to our generating systems between 2008 and 2012.

Multi-Pollutant Legislation

The United States Congress has been working on legislation to consolidate
the numerous air pollution regulations facing the utility industry. This
"multi-pollutant" legislation is expected to be deliberated in Congress in 2003.
While the cost to comply with such legislation, if enacted, could be
significant, it is anticipated that the costs would be less than the combined
impact of the new National Ambient Air Quality Standards, mercury and Regional
Haze regulations, discussed above. Pollution control costs under such
legislation are expected to be incurred in phases from 2007 through 2015. At
this time, we are unable to predict the ultimate impact of the above expected
regulations and this legislation on our future financial condition, results of
operations, or liquidity; however, the impact could be material.

Future initiatives regarding greenhouse gas emissions and global warming
continue to be the subject of much debate. The related Kyoto Protocol was signed
by the United States but has since been rejected by the President, who instead
has asked for an 18% decrease in carbon intensity on a voluntary basis. Future
initiatives on this issue and the ultimate effects of the Kyoto Protocol and the
President's initiatives on us are unknown. As a result of our diverse fuel
portfolio, our contribution to greenhouse gases varies. Coal-fired power plants,
however, are significant sources of carbon dioxide emissions, a principal
greenhouse gas. Therefore, our compliance costs with any mandated federal
greenhouse gas reductions in the future could be material.

Clean Water Act

In April 2002, the EPA proposed rules under the Clean Water Act that
require that cooling water intake structures reflect the best technology
available for minimizing adverse environmental impacts. These rules pertain to
existing generating facilities that currently employ a cooling water intake
structure whose flow exceeds 50 million gallons per day. A final action on the
proposed rules is expected by August 2003. The proposed rule may require us to
install additional intake screens or other protective measures, as well as
extensive site specific study and monitoring requirements. There is also the
possibility that the proposed rules may lead to the installation of cooling
towers on some of our facilities. Our compliance costs associated with the final
rules are unknown, but could be material.

55


Remediation

We are involved in a number of remediation actions to clean up hazardous
waste sites as required by federal and state law. Such statutes require that
responsible parties fund remediation actions regardless of fault, legality of
original disposal, or ownership of a disposal site. We have been identified by
the federal or state governments as a potentially responsible party (PRP) at
several contaminated sites.

We own or are otherwise responsible for one former manufactured gas plant
(MGP) site in Illinois, 10 sites in Missouri and one site in Iowa. The ICC
permits the recovery of remediation and litigation costs associated with our
former MGP site located in Illinois from our Illinois electric and natural gas
utility customers through environmental adjustment clause rate riders. To be
recoverable, such costs must be prudently and properly incurred and are subject
to annual reconciliation review by the ICC. Unlike Illinois, we do not have in
effect in Missouri a rate rider mechanism which permits remediation costs
associated with MGP sites to be recovered from utility customers, and we do not
have any retail utility operations in Iowa. Because of the unknown and unique
characteristics of each site (such as amount and type of residues present,
physical characteristics of the site and the environmental risk), and uncertain
regulatory requirements, we are not able to determine the maximum liability for
the remediation of these sites. However, we have estimated that the liability is
at a minimum $13 million. Therefore, in accordance with generally accepted
accounting principles, we have recorded a liability of $13 million. At this
time, we are unable to determine what portion of these costs, if any, will be
eligible for recovery from insurance carriers.

In June 2000, the EPA notified us and numerous other companies that former
landfills and lagoons in Sauget, Illinois, may contain soil and groundwater
contamination. These sites are known as Sauget Area 1 and Sauget Area 2. From
approximately 1926 until 1976, we operated a power generating facility adjacent
to Sauget Area 2 and currently own and operate electric transmission and
distribution facilities in or near Sauget Areas 1 and 2.

In September 2000, the United States Department of Justice was granted
leave by the United States District Court - Southern District of Illinois to add
numerous additional parties, including us, to a preexisting lawsuit between the
government and others. The government seeks recovery of response costs under the
Comprehensive Environmental Response Compensation Liability Act of 1980 (CERCLA
or Superfund), incurred in connection with the remediation of Sauget Area 1. We
believe the final resolution of this lawsuit and the remediation of Sauget Area
1 will not have a material adverse effect on our financial position, results of
operations or liquidity.

In September 2001, the EPA proposed in the Federal Register that Sauget
Area 1 and Sauget Area 2 be listed on the National Priorities List (NPL). The
inclusion of a site on the NPL allows the EPA to access Superfund trust monies
to fund site remediations. With respect to Sauget Area 2, we have joined with
other PRPs to evaluate the extent of potential contamination. We are unable to
predict the ultimate impact of the Sauget Area 2 site on our financial position,
results of operations or liquidity.

In October 2002, we were included in a Unilateral Administrative Order
(UAO) list of potentially liable parties for groundwater contamination for a
portion of the Sauget Area 2 site. The UAO encompasses the groundwater
contamination releasing to the Mississippi River adjacent to a chemical
company's former chemical waste landfill and the resulting impact area in the
Mississippi River. We are being asked to participate in response activities that
involve the installation of a barrier wall with three recovery wells. The
projected cost for this remedy method is $26 million. In November 2002, we sent
a letter to the EPA asserting our defenses to the UAO and requested our removal
from the list of potentially responsible parties under the UAO.

In addition, our operations, or that of our predecessor companies, involve
the use, disposal and, in appropriate circumstances, the cleanup of substances
regulated under environmental protection laws. We are unable to determine the
impact these actions may have on our financial position, results of operations
or liquidity.

Labor Agreements

Certain employees of AmerenUE are represented by the International
Brotherhood of Electrical Workers (IBEW) and the International Union of
Operating Engineers (IUOE). These employees comprise approximately 75% of our
workforce. Labor agreements covering 10% of employees extend through 2006. Labor
agreements covering the remaining employees represented by IBEW and IUOE expire
by June 2003. We cannot predict what issues may be raised by the collective
bargaining units and, if raised, whether negotiations concerning such issues
will be successfully concluded.


56



Asbestos-Related Litigation

We, along with Ameren and AmerenCIPS, have been named, along with numerous
other parties, in a number of lawsuits which have been filed by certain
plaintiffs claiming varying degrees of injury from asbestos exposure. Most have
been filed in the Circuit Court of Madison County, Illinois. The number of total
defendants named in each case is significant with as many as 110 parties named
in a case to as few as six. However, the average number of parties is 54 in the
cases that are currently pending.

The claims filed against the Ameren companies allege injury from asbestos
exposure during the plaintiffs' activities at the Ameren companies' electric
generating plants (in the case of AmerenCIPS, its former plants are now owned by
Generating Company). In each lawsuit, the plaintiff seeks unspecified damages in
excess of $50,000, which typically would be shared among the named defendants. A
total of 121 such lawsuits have been filed against the Ameren companies of which
45 are pending, 14 have been settled and 62 have been dismissed.

Regulation

Regulatory changes enacted and being considered at the federal and state
levels continue to change the structure of the utility industry and utility
regulation, as well as encourage increased competition. At this time, we are
unable to predict the impact of these changes on our future financial condition,
results of operations or liquidity. See Note 2 - Rate and Regulatory Matters for
further information.


NOTE 15 - Callaway Nuclear Plant

Under the Nuclear Waste Policy Act of 1982, the Department of Energy (DOE)
is responsible for the permanent storage and disposal of spent nuclear fuel. The
DOE currently charges one mill, or 1/10 of one cent, per nuclear-generated
kilowatthour sold for future disposal of spent fuel. Pursuant to this Act, we
collect one mill from our customers for each kilowatthour of electricity that we
generate from Callaway. Electric utility rates charged to customers provide for
recovery of such costs. The DOE is not expected to have its permanent storage
facility for spent fuel available until at least 2015. We have sufficient
storage capacity at Callaway until 2020 and have the capability for additional
storage capacity through the licensed life of the plant. The delayed
availability of the DOE's disposal facility is not expected to adversely affect
the continued operation of Callaway through its currently licensed life.

Electric utility rates charged to customers provide for recovery of
Callaway decommissioning costs over the life of the plant, based on an assumed
40-year life, ending with expiration of the plant's operating license in 2024.
The Callaway site is assumed to be decommissioned based on immediate
dismantlement method and removal from service. Decommissioning costs, including
decontamination, dismantling and site restoration, are estimated to be $515
million in current year dollars and are expected to escalate approximately 4%
per year through the end of decommissioning activity in 2033. Decommissioning
costs are charged to depreciation expense over Callaway's service life and
amounted to approximately $7 million in each of the years 2002, 2001 and 2000.
Every three years, the MoPSC and ICC require us to file updated cost studies for
decommissioning Callaway, and electric rates may be adjusted at such times to
reflect changed estimates. The latest studies were filed in 2002. Costs
collected from customers are deposited in an external trust fund to provide for
Callaway's decommissioning. Fund earnings are expected to average approximately
9.5% annually through the date of decommissioning. If the assumed return on
trust assets is not earned, we believe it is probable that any such earnings
deficiency will be recovered in rates. Trust fund earnings, net of expenses,
appear on the balance sheet as increases in the nuclear decommissioning trust
fund and in the accumulated provision for nuclear decommissioning.

The FASB issued SFAS 143 (see Note 1 - Summary of Significant Accounting
Policies for further information), which will result in a change to our
recognition, measurement, and classification of nuclear decommissioning costs.

NOTE 16 - Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value
of each class of financial instruments for which it is practicable to estimate
that value:

Cash and Temporary Investments/Short-Term Borrowings

The carrying amounts approximate fair value because of the short-term
maturity of these instruments.

Nuclear Decommissioning Trust Fund

The fair value is estimated based on quoted market prices for securities.

Preferred Stock

The fair value is estimated based on the quoted market prices for the same
or similar issues.

Long-Term Debt

The fair value is estimated based on the quoted market prices for same or
similar issues or on the current rates offered to AmerenUE for debt of
comparable maturities.

Derivative Financial Instruments

Market prices used to determine fair value are based on management's
estimates, which take into consideration factors like closing exchange prices,
over-the-counter prices, and time value of money and volatility factors. All
derivative financial instruments are carried at fair value on the balance sheet.

Carrying amounts and estimated fair values of our financial instruments at
December 31, 2002 and 2001 were as follows:

2002 2001
- --------------------------------------------------------------------------------
Carrying Fair Carrying Fair
Amount Value Amount Value
- --------------------------------------------------------------------------------
Long-term debt (including current portion) $1,817 $1,878 $1,691 $1,727
Preferred stock 113 98 155 138
- --------------------------------------------------------------------------------

We have investments in debt and equity securities that are held in trust
funds for the purpose of funding the nuclear decommissioning of our Callaway
site. See Note 15 - Callaway Nuclear Plant for further information. We have
classified these investments in debt and equity securities as available for sale
and have recorded all such investments at their fair market value at December
31, 2002 and 2001. Investments by the nuclear decommissioning trust funds are
allocated 60% to 65% to equity securities with the balance invested in fixed
income securities. Fixed income investments are limited to U.S. government or
agency securities, municipal bonds or investment-grade corporate securities. The
proceeds from the sale of investments were $141 million in 2002 (2001 - $230
million; 2000 - $61 million). Using the specific identification method to
determine cost, the gross realized gains on those sales were approximately $35
million for 2002 (2001 - $4 million; 2000 - $1 million). Net realized and
unrealized gains and losses are reflected in the accumulated provision for
nuclear decommissioning on the balance sheet, which is consistent with the
method we use to account for the decommissioning costs recovered in rates. Gains
or losses on assets in the trusts could result in lower or higher funding
requirements for decommissioning costs, which we believe would be reflected in
electric rates paid by customers.

Costs and fair values of investments in debt and equity securities in the
nuclear decommissioning trust fund at December 31, 2002 and 2001 were as
follows:

- --------------------------------------------------------------------------------
2002 Gross Unrealized Gross Unrealized
Security Type Cost Gain (Loss) Fair Value
- --------------------------------------------------------------------------------
Debt securities $ 57 $ 4 $ - $ 61
Equity securities 89 17 - 106
Cash equivalents 5 - 5
- --------------------------------------------------------------------------------
$ 151 $ 21 $ - $ 172
- --------------------------------------------------------------------------------

2001 Gross Unrealized Gross Unrealized

Equity securities 78 44 - 122
Cash equivalents 6 - - 6
- --------------------------------------------------------------------------------
$141 $ 46 $ - $ 187
- --------------------------------------------------------------------------------

The contractual maturities of investments in debt securities at December
31, 2002, were as follows:
- --------------------------------------------------------------------------------
Cost Fair Value
- --------------------------------------------------------------------------------
Less than 5 years $22 $23
5 years to 10 years 20 21

NOTE 17 - Subsequent Events

CILCORP Acquisition

On January 31, 2003, after receipt of the necessary regulatory agency
approvals and clearance from the Department of Justice under the
Hart-Scott-Rodino Antitrust Improvements Act, Ameren completed its acquisition
of all of the outstanding common stock of CILCORP from AES. CILCORP is the
parent company of Peoria, Illinois-based Central Illinois Light Company, which
operated as CILCO. With the acquisition, CILCO became an Ameren subsidiary, but
remains a separate utility company, operating as AmerenCILCO. On February 4,
2003, Ameren also completed its acquisition of AES Medina Valley Cogen (No. 4),
LLC, which indirectly owns a 40 megawatt, gas-fired electric co-generation
plant. With the acquisition, Medina Valley became a wholly-owned subsidiary of
Resources Company and was renamed as AmerenEnergy Medina Valley Cogen (No. 4),
LLC. The CILCORP and AmerenEnergy Medina Valley Cogen (No. 4), LLC financial
statements will be included in Ameren's consolidated financial statements
effective with the January and February 2003 acquisition dates.

Ameren acquired CILCORP to complement its existing Illinois gas and
electric operations. The purchase includes CILCO's rate-regulated electric and
natural gas businesses in Illinois serving approximately 200,000 and 205,000
customers, respectively, of which approximately 150,000 are combination electric
and gas customers. CILCO's service territory is contiguous to Ameren's service
territory. CILCO also has a non rate-regulated electric and gas marketing
business principally focused in the Chicago, Illinois region. Finally, the
purchase includes approximately 1,200 megawatts of largely coal-fired generating
capacity, most of which is expected to be non rate-regulated in 2003.

The total purchase price was approximately $1.4 billion and included the
assumption of CILCORP and Medina Valley debt and preferred stock at closing of
approximately $900 million, with the balance of the purchase price of
approximately $500 million paid with cash on hand. The purchase price is subject
to certain adjustments for working capital and other changes pending the
finalization of CILCORP's closing balance sheet. The cash component of the
purchase price came from Ameren's issuances in September 2002 of 8.05 million
common shares and in early 2003 of 6.325 million common shares.

Debt Financing

In August 2002, a shelf registration statement filed by us with the SEC on
Form S-3 was declared effective. This statement authorized the offering from
time to time of up to $750 million of various forms of long-term debt and trust
preferred securities to refinance existing debt and preferred stock and for
general corporate purposes, including the repayment of short-term debt incurred
to finance construction expenditures and other working capital needs. On March
10, 2003, we issued, pursuant to the shelf registration referred to above, $184
million of 5.50% Senior Secured Notes due March 15, 2034. We expect to use the
net proceeds of the issuance of approximately $180 million, along with other
funds to redeem prior to maturity $104 million principal amount of outstanding
8.25% first mortgage bonds due October 15, 2022, at a redemption price of
103.61% of par, plus accrued interest, and to repay short-term debt incurred to
pay at maturity $75 million principal amount of 8.33% first mortgage bonds that
were due in December 2002. We may sell all, or a portion of, the remaining
registered securities under the shelf registration statement if warranted by
market conditions and our capital requirements. Any offer and sale will be

59


made only by means of a prospectus meeting the requirements of the Securities
Act of 1933 and the rules and regulations thereunder. At March 10, 2003, the
amount remaining on the shelf registration statement was $393 million.

diligently prosecutes such contest, at all times effectively stays or prevents
any official or judicial sale of the Project, or any part thereof or interest
therein, under execution or otherwise, and pays or otherwise satisfies any final

Section 8.6. Option to Purchase Unimproved Portions of the Project Site.
The City hereby grants to the Company the right at any time and from time to
time to purchase any unimproved portion or portions of the Project Site. For the
purposes of this Section "unimproved" shall mean real property upon which no
Project Improvements are located, but excluding improvements relating to
streets, sidewalks, bridges, storm water, grading, utility, parking or other
similar improvements. As conditions to such purchase, the City and the Trustee
shall receive from the Company at least 30 days prior to the proposed date for
completing the purchase the following (a) a written certificate from the Company
to the effect (i) that the Company desires to purchase an unimproved portion of
the Project Site, (ii) the proposed date for completing the purchase, and (iii)
that the Company is not in material default under any of the provisions of this
Lease Agreement, (b) an adequate legal description of that portion (together
with the interest in such portion) of the property to be purchased, (c) a
certificate of an independent engineer or surveyor, dated not more than 30 days
prior to the date of the request stating that, in the opinion of the person
signing such certificate; (i) the unimproved portion of the Project Site is
unimproved within the definition contained in this Section, (ii) the unimproved
portion of the Project Site so proposed to be purchased is not needed for the
operation of the Project, and (iii) the proposed purchase will not impair the
usefulness of the Project for its intended purposes and will not destroy the
means of ingress thereto and egress therefrom, and (d) the written consent of
the Owners of all of the Bonds.

The purchase price for such unimproved portion of the Project Site shall be
its fair market value as determined by the Owners of all of the Bonds and shall
be received in writing by the City and the Trustee at least 10 days prior to the
proposed date for completing the purchase. Such purchase price shall be paid to
the Trustee at the time the City executes and delivers a special warranty deed
conveying the property which is to be purchased to the Company. The Trustee
shall deposit such amount (if any) into the Bond Fund. If such amount is more
than $1,000, such amount shall be used by the Trustee to redeem Bonds in
accordance with Section 302(a) of the Indenture. If such amount is $1,000 or
less the Trustee shall apply such amount to the next interest payment on the
Bonds.

Upon the City's receipt of written notice from the Trustee that the Trustee
has received all of the items required by this Section, the Mayor and City Clerk
of the City shall execute a special warranty deed conveying such property to the
Company and shall deliver such deed to the Company. Such special warranty deed
shall be subject to the following: (a) those liens and encumbrances, if any, to
which title to that portion of the Project Site was subject when conveyed to the
City; (b) those liens and encumbrances created by the Company or to the creation
or suffering of which the Company consented; (c) those liens and encumbrances
resulting from the failure of the Company to perform or observe any agreement on
its part contained in this Lease; (d) Permitted Encumbrances other than the
Indenture, this Lease and the Deed of Trust; and (e) if the unimproved portion
of the Project Site or any part thereof is being condemned, the rights and title

DAMAGE, DESTRUCTION AND CONDEMNATION

Section 9.1. Damage or Destruction.

(a) If the Project shall be damaged or destroyed by fire or any other
casualty, whether or not covered by insurance, the Company, as promptly as
practicable, shall either (i) make the determination described in subsection (f)
below, or (ii) repair, restore, replace or rebuild the same so that upon
completion of such repairs, restoration, replacement or rebuilding such Project
shall be of a value not less than the value thereof immediately prior to the
occurrence of such damage or destruction or, at the Company's option, shall
construct upon the Project Site new buildings and improvements thereafter
together with all new machinery, equipment and fixtures which are either to be
attached to or are to be used in connection with the operation or maintenance
thereof, provided that (A) the value thereof shall not be less than the value of
such destroyed or damaged Project Improvements and/or Project Equipment
immediately prior to the occurrence of such damage or destruction and (B) the
nature of such new buildings, improvements, machinery, equipment and fixtures
will not impair the character of the Project as an enterprise permitted by the
Act.

If the Company shall elect to construct any such new buildings and
improvements, for all purposes of this Lease, any reference to the words
"Project Improvements" shall be deemed to also include any such new buildings
and improvements and all additions thereto and all replacements and alterations
thereof and any reference to the words "Project Equipment" shall be deemed to
include any such new machinery, equipment and fixtures which are either attached
to or are used in connection with the operation or maintenance of such new
buildings and improvements and all additions or replacements thereof.

Unless the Company makes the determination described in subsection (f)
below, the Net Proceeds of casualty insurance required by Article VII hereof
received with respect to such damage or loss to the Project shall be used to pay
the cost of repairing, restoring, replacing or rebuilding the Project or any
part thereof. Insurance monies in an amount less than $5,000,000 may be paid to
or retained by the Company to be paid for such costs. Insurance monies in an
amount of $5,000,000 or more shall be paid to the Trustee to be used as provided
herein. If the Company makes the determination described in subsection (f)
below, the Net Proceeds shall be deposited with the Trustee and used to redeem
Bonds as provided in subsection (f).

(b) If any of the insurance monies paid by the insurance company as
hereinabove provided shall remain after the completion of such repairs,
restoration, replacement or rebuilding, and this Lease shall not have
terminated, the excess shall be deposited in the Bond Fund, subject to the
rights pursuant to any Leasehold Mortgage or Financing Document. If the Net
Proceeds shall be insufficient to pay the entire cost of such repairs,
restoration, replacement or rebuilding, the Company shall pay the deficiency.

(c) Except as otherwise provided in this Lease, in the event of any such
damage by fire or any other casualty, the provisions of this Lease shall be
unaffected and the Company shall remain and continue liable for the payment of
all Basic Rent and Additional Rental and all other charges required hereunder to
be paid by the Company, as though no damage by fire or any other casualty has
occurred.

(d) The City and the Company agree that they will cooperate with each
other, to such extent as such other party may reasonably require, in connection
with the prosecution or defense, at the expense of the Company, of any action or
proceeding arising out of, or for the collection of any insurance monies that
may be due in the event of, any loss or damage, and that they will execute and
deliver to such other parties such instruments as may be required to facilitate
the recovery of any insurance monies.

(e) The Company agrees to give prompt notice to the City, the Trustee, the
mortgagee under the Leasehold Mortgage (if any) and the Financing Party under
the Financing Document (if any) with respect to all fires and any other
casualties occurring in, on, at or about the Project.

(f) If the Company shall determine that rebuilding, repairing, restoring or
replacing the Project is not practicable and desirable, any Net Proceeds of
casualty insurance required by Article VII hereof received with respect to such
damage or loss shall, after payment of all Additional Rent then due and payable,
be paid into the Bond Fund and shall be used, at the option of the Company, to
redeem Bonds on the earliest practicable redemption date or to pay the principal
of any Bonds as the same become due, all subject to rights of the mortgagee
under the Leasehold Mortgage (if any) and the Financing Party under the
Financing Documents (if any). The Company agrees to be reasonable in exercising
its judgment pursuant to this subsection (f).

(g) The Company shall not, by reason of its inability to use all or any
part of the Project during any period in which the Project is damaged or
destroyed or is being repaired, rebuilt, restored or replaced, nor by reason of
the payment of the costs of such rebuilding, repairing, restoring or replacing,
be entitled to any reimbursement from the City, the Trustee or the Bondowners or
to any abatement or diminution of the rentals payable by the Company under this
Lease or of any other obligations of the Company under this Lease except as
expressly provided in this Section.

Section 9.2. Condemnation.

(a) If during the Lease Term, title to, or the temporary use of, all or any
part of the Project shall be condemned by or sold under threat of condemnation
to any authority possessing the power of eminent domain, to such extent that the
claim or loss resulting from such condemnation is greater than $5,000,000, the
Company shall, within 90 days after the date of entry of a final order in any
eminent domain proceedings granting condemnation or the date of sale under
threat of condemnation, notify the City, the Trustee, the mortgagee under the
Leasehold Mortgage (if any) and the Financing Party under the Financing Document
(if any) in writing as to the nature and extent of such condemnation or loss of
title and whether it is practicable and desirable to acquire or construct
substitute improvements.

(b) If the Company shall determine that such substitution is practicable
and desirable, the Company shall proceed promptly with and complete with
reasonable dispatch the acquisition or construction of such substitute
improvements, so as to place the Project in substantially the same condition as
existed prior to the exercise of the said power of eminent domain, including the
acquisition or construction of other improvements suitable for the Company's
operations at the Project (which improvements will be deemed a part of the
Project and available for use and occupancy by the Company without the payment
of any rent other than herein provided, to the same extent as if such other
improvements were specifically described herein and demised hereby); provided,
that such improvements will be acquired by the City subject to no liens,
security interests or encumbrances prior to the lien and/or security interest
afforded by the Indenture, this Lease and the Deed of Trust other than Permitted
Encumbrances. In such case, any Net Proceeds received from any award or awards
with respect to the Project or any part thereof made in such condemnation or
eminent domain proceedings, or of the sale proceeds, shall be applied in the
same manner as provided in Section 9.1 hereof (with respect to the receipt of
casualty insurance proceeds).

(c) If the Company shall determine that it is not practicable and desirable
to acquire or construct substitute improvements, any Net Proceeds of
condemnation awards received by the Company

-15-



shall, after payment of all Additional Rent then due and payable, be paid into
the Bond Fund and shall be used, at the option of the Company, to redeem Bonds
on the earliest practicable redemption date or to pay the principal of any Bonds
as the same becomes due and payable, all subject to the rights of the mortgagee
under the Leasehold Mortgage (if any) and Financing Party under the Financing
Documents (if any).

(d) The Company shall not, by reason of its inability to use all or any
part of the Project during any such period of restoration or acquisition nor by
reason of the payment of the costs of such restoration or acquisition, be
entitled to any reimbursement from the City, the Trustee or the Bondowners or to
any abatement or diminution of the rentals payable by the Company under this
Lease nor of any other obligations hereunder except as expressly provided in
this Section.

(e) The City shall cooperate fully with the Company in the handling and
conduct of any prospective or pending condemnation proceedings with respect to
the Project or any part thereof, and shall, to the extent it may lawfully do so,
permit the Company to litigate in any such proceeding in the name and on behalf
of the City. The Company shall hold the City whole and harmless from any loss,
costs or expenses the City may incur related to any such proceeding. In no event
will the City voluntarily settle or consent to the settlement of any prospective
or pending condemnation proceedings with respect to the Project or any part
thereof without the prior written consent of the Company.

Section 9.3. Bondowner Approval. Notwithstanding anything to the contrary
contained in this Article IX, the proceeds of any insurance received subsequent
to a casualty or of any condemnation proceedings (or threats thereof) may be
applied as directed by the Owners of 100% of the principal amount of Bonds
outstanding, subject and subordinate to the rights of the City and the Trustee
pursuant to the Indenture, this Lease or the Grant Agreement.

Section 10.2. Surrender of Possession. Upon accrual of the City's right of
re-entry because of the Company's default hereunder or upon the cancellation or
termination of this Lease for any reason other than the Company's purchase of

shall have the right within 90 days (or such later date as the City may agree
to) after the termination of this Lease to remove from the Project Site any
buildings, improvements, furniture, trade fixtures, machinery and equipment
owned by the Company and not constituting part of the Project. All repairs to
and restorations of the Project required to be made because of such removal
shall be made by and at the sole cost and expense of the Company, and during
said 90-day (or extended) period the Company shall bear the sole responsibility
for and bear the sole risk of loss for said buildings, improvements, furniture,

shall be the separate and absolute property of the City.

Section 10.3. Right of Access to the Project. The Company agrees that the

Encumbrance. If no Event of Default shall have happened and be continuing beyond
any applicable grace period, any payments or other consideration received by the
Company for any such grant or with respect to or under any such agreement or
other arrangement shall be and remain the property of the Company, but, subject
to Sections 10.4(c) and (d), in the event of the termination of this Lease or
Event of Default by the Company, all rights then existing of the Company with
respect to or under such grant shall inure to the benefit of and be exercisable

one or more Financing Documents under which it has granted rights in this Lease
to a Financing Party, which includes the name and address of such Financing
Party, then the following provisions shall apply in respect of each such
Financing Party:

(i) there shall be no merger of this Lease or of the leasehold estate
created hereby with the fee title to the Project, notwithstanding that this
Lease or said leasehold estate and said fee title shall be owned by the
same person or persons, without the prior written consent of such Financing
Party;

(ii) the City shall serve upon each such Financing Party (at the
address, if any, provided to the City) a copy of each notice of the

copy thereof is thus served upon each Financing Party;

(iii) each Financing Party shall have the same period of time which
the Company has, after the service of any required notice upon it, within

such cure); provided that the Financing Party (or its designee, nominee,
assignee or transferee) shall pay or cause to be paid to the City and the
Trustee all expenses, including reasonable counsel fees, court costs and

or transferees) shall have the right to enter, possess and use the Project
at such reasonable times and manner as are necessary or desirable to
effectuate the remedies and enforce their respective rights under the
Financing Documents.

(e) In connection with the execution of one or more Financing Documents,
upon the request of the Company, the City agrees to execute such documents as

or provision for their payment having been made pursuant to Article XIII of the
Indenture. To exercise such option the Company shall give written notice to the

notice is mailed, and in case of a redemption of the Bonds in accordance with
the provisions of the Indenture the Company shall make arrangements satisfactory
to the Trustee for the giving of the required notice of redemption. The purchase
price payable by the Company in the event of its exercise of the option granted
in this Section shall be the sum of the following:

(a) an amount of money which, when added to the amount then on deposit
in the Bond Fund, will be sufficient to redeem all the then outstanding
Bonds on the earliest redemption date next succeeding the closing date,
including, without limitation, principal and interest to accrue to said
redemption date and redemption expense; plus

(b) an amount of money equal to the Trustee's and the Paying Agent's

pursuant to the Grant Agreement which shall have accrued as of the date of
purchase; plus

(d) the sum of $1,000.

At its option, to be exercised at least 5 Business Days prior to the date
of closing such purchase, the Company may deliver to the Trustee for
cancellation Bonds not previously paid, and the Company shall receive a credit
against the purchase price payable by the Company in an amount equal to 100% of
the principal amount of the Bonds so delivered for cancellation, plus the
accrued interest thereon.

the Project pursuant to this Article, the City will upon receipt of the purchase
price deliver, or cause to be delivered, to the Company the following:

full, a release from the Trustee of the Project from the lien and/or

(b) Documents, including without limitation a special warranty deed,
conveying to the Company legal title to the Project, as it then exists,
subject to the following: (i) those liens and encumbrances, if any, to
which title to the Project was subject when conveyed to the City;
(ii) those liens and encumbrances created by the Company or to the creation
or suffering of which the

-22-



Company consented; (iii) those liens and encumbrances resulting from the
failure of the Company to perform or observe any of the agreements on its
part contained in this Lease; (iv) Permitted Encumbrances other than the
Indenture, this Lease and the Deed of Trust; and (v) if the Project or any
part thereof is being condemned, the rights and title of any condemning
authority.

Section 11.3. Relative Position of Option and Indenture. The options and
obligation to purchase the Project granted to the Company in this Article shall
be and remain prior and superior to the Indenture and may be exercised whether
or not the Company is in default under this Lease, provided that such default
will not result in nonfulfillment of any condition to the exercise of any such
option and further provided that all options herein granted shall terminate upon
the termination of this Lease.

Section 11.4. Obligation to Purchase the Project. The Company hereby agrees
to purchase, and the City hereby agrees to sell, the Project (a) for the sum of
$1,000 at the expiration of the Lease Term following full payment of the Bonds
or provision for payment thereof having been made in accordance with the
provisions of the Indenture, and (b) at least 30 days and not more than 90 days
subsequent to the early termination of the Grant Agreement, in an amount
sufficient to redeem all the then Outstanding Bonds, plus accrued interest, the
reasonable fees and expenses of the Trustee and the sum of $1,000.

Company has commenced such cure within such sixty (60) day period, and (B)
the Company diligently prosecutes such cure to completion.

Section 12.2. Remedies on Default. If any Event of Default referred to in
Section 12.1 hereof shall have occurred and be continuing, then the City may at
the City's election (subject, however, to any restrictions against acceleration
of the maturity of the Bonds or termination of this Lease in the Indenture),
then or at any time thereafter, and while such default shall continue, take any
one or more of the following actions:

(a) cause all amounts payable with respect to the Bonds for the remainder
of the term of this Lease to become due and payable, as provided in the
Indenture;

(b) give the Company written notice of intention to terminate this Lease on
a date specified therein, which date shall not be earlier than 60 days after
such notice is given, and if all defaults have not then been cured, on the date
so specified, the Company's rights to possession of the Project shall cease and
this Lease shall thereupon be terminated, and the City may re-enter and take
possession of the Project; or

(c) without terminating this Lease, re-enter the Project to take possession
thereof pursuant to legal proceedings or pursuant to any notice provided for by
law, and having elected to re-enter or take possession of the Project without
terminating this Lease, the City shall use reasonable diligence to relet the
Project, or parts thereof, for such term or terms and at such rental and upon
such other terms and conditions as the City may deem advisable, with the right
to make alterations and repairs to the Project, and no such re-entry or taking
of possession of the Project by the City shall be construed as an election on
the City's part to terminate this Lease, and no such re-entry or taking of
possession by the City shall relieve the Company of its obligation to pay Basic
Rent or Additional Rent (at the time or times provided herein), or any of its
other obligations under this Lease, all of which shall survive such re-entry or
taking of possession, and the Company shall continue to pay the Basic Rent and
Additional Rent provided for in this Lease until the end of this Lease Term,
whether or not the Project shall have been relet, less the Net Proceeds, if any,
of any reletting of the Project after deducting all of the City's reasonable
expenses in or in connection with such reletting, including without limitation
all repossession costs, brokerage commissions, legal expenses,

-24-




expenses of employees, expenses for title reports, commitments or policies,
alteration costs and expenses of preparation for reletting. Said Net Proceeds of
any reletting shall be deposited in the Bond Fund. Having elected to re-enter or
take possession of the Project without terminating this Lease, the City may
(subject, however, to any restrictions against termination of this Lease in the
Indenture), by notice to the Company given at any time thereafter while the
Company is in default in the payment of Basic Rent or Additional Rent or in the
performance of any other obligation under this Lease, elect to terminate this
Lease on a date to be specified in such notice, which date shall be not earlier
than 30 days after re-entry under (c) above, and if all defaults shall not have
then been cured, on the date so specified this Lease shall thereupon be
terminated. If in accordance with any of the foregoing provisions of this
Article the City shall have the right to elect to re-enter and take possession
of the Project, the City may enter and expel the Company and those claiming
through or under the Company and remove the property and effects of both or
either without being guilty of any manner of trespass and without prejudice to
any remedies for arrears of rent or preceding breach of covenant. The City may
take whatever action at law or in equity which may appear necessary or desirable
to collect rent then due and thereafter to become due, or to enforce performance
and observance of any obligation, agreement or covenant of the Company under
this Lease.

Section 12.3. Survival of Obligations. The Company covenants and agrees
with the City and Bondowners that its obligations under this Lease shall survive
the cancellation and termination of this Lease, for any cause, and that the
Company shall continue to pay the Basic Rent and Additional Rent and perform all
other obligations provided for in this Lease, all at the time or times provided
in this Lease; provided, however, that upon the payment of all Basic Rent and
Additional Rent required under Article V hereof, and upon the satisfaction and
discharge of the Indenture under Section 1301 thereof, the Company's obligation
under this Lease shall thereupon cease and terminate in full.

Section 12.4. Rights and Remedies Cumulative. The rights and remedies
reserved by the City and the Company hereunder and those provided by law shall
be construed as cumulative and continuing rights. No one of them shall be
exhausted by the exercise thereof on one or more occasions. The City and the
Company shall each be entitled to specific performance and injunctive or other
equitable relief for any breach or threatened breach of any of the provisions of
this Lease, notwithstanding availability of an adequate remedy at law, and each
party hereby waives the right to raise such defense in any proceeding in equity.
The City agrees that neither the City nor the Trustee shall enforce any right or
obligation hereunder (except for the City's or the Trustee's right to receive
payments for their own account under the Indenture, the Lease, the Grant
Agreement or any other agreement related to the Bonds or for their rights of
indemnification or to be protected from liabilities by insurance policies
required by this Lease) if so directed in writing by the Owners of 100% of the
Outstanding Bonds.

Section 12.5. Waiver of Breach. No waiver of any breach of any covenant or
agreement herein contained shall operate as a waiver of any subsequent breach of
the same covenant or agreement or as a waiver of any breach of any other
covenant or agreement, and in case of a breach by the Company of any covenant,
agreement or undertaking by the Company, the City may nevertheless accept from
the Company any payment or payments hereunder without in any way waiving City's
right to exercise any of its rights and remedies provided for herein with
respect to any such default or defaults of the Company which were in existence
at the time such payment or payments were accepted by the City.

Section 12.6. Opportunity of Company to Cure Defaults. With regard to any
alleged default concerning which notice is given to the Company under the
provisions of this Article, the City hereby grants the Company full authority
for account of the City to perform any covenant or obligation, the
nonperformance of which is alleged in said notice to constitute a default, in
the name and stead of the City,

-25-




with full power to do any and all things and acts to the same extent that the
City could do and perform any such things and acts in order to remedy such
default.

Section 12.7. Trustee's Exercise of the City's Remedies. Whenever any event
of default shall have occurred and be continuing, the Trustee may, but except as
otherwise provided in the Indenture shall not be obliged to, exercise any or all
of the rights of the City under this Article, upon notice as required of the
City unless the City has already given the required notice. In addition, the
Trustee shall have available to it all of the remedies prescribed by the
Indenture.

-7-




Section 202. Nature of Obligation. The Bonds and the interest thereon shall
be special obligations of the City payable solely out of the rents, revenues and
receipts derived by the City from the Project and the Lease, and not from any
other fund or source of the City, and are secured by a pledge and assignment of
the Trust Estate to the Trustee in favor of the Owners of the Bonds, as provided
in this Indenture and the Deed of Trust. The Bonds and the interest thereon
shall not constitute general obligations of the City or the State of Missouri,
and neither the City nor said State shall be liable thereon, and the Bonds shall
not constitute an indebtedness within the meaning of any constitutional or
statutory debt limitation or restriction, and are not payable in any manner by
taxation.

Section 203. Denomination, Number and Dating of Bond.

(a) The Series 2002 Bond may be issuable in the form of one fully
registered Bond without coupons in the maximum principal denomination of
$125,000,000 or in denominations of $10,000,000 or integral multiples of $1.00
in excess thereof. The Bond shall be substantially in the form hereinafter set
forth in Article IV of this Indenture.

(b) The Series 2002 Bond shall be dated by the Trustee as of the date of
initial delivery thereof as provided herein. If the Series 2002 Bond is at any
time thereafter transferred, any Series 2002 Bond replacing such Bond shall be
dated as of the date of authentication thereof.

Section 204. Method and Place of Payment of Bonds.

(a) The principal of and interest on the Bonds shall be payable in any coin
or currency of the United States of America which on the respective dates of
payment thereof is legal tender for payment of public and private debts.

(b) Payment of the principal of the Bonds shall be made upon the
presentation and surrender of such Bond at the principal payment office of any
Paying Agent; provided, that so long as the Company or any entity controlled by,
under common control with or controlling the Company is the sole Bondowner, the
Trustee is authorized to make payments of principal on such Bond by internal
bank transfer or by wire transfer to an account at a commercial bank or savings
institution designated by such Bondowner and located in the continental United
States; provided, further, that upon such payment by internal bank transfer or
by wire transfer of principal on such Bond, the Trustee shall record the amount
of such principal payment on the registration books for the Bond maintained by
the Trustee on behalf of the City. If any Bond is presented to the Trustee
together with such payment, or for such payment, the Trustee shall enter the
amount of such principal payment on the Table of Cumulative Outstanding
Principal Amount on the Bond in the manner provided by Section 402 hereof.
Notwithstanding the foregoing, the registration books maintained by the Trustee
shall be the official record of the Cumulative Outstanding Principal Amount on
the Bond at any time, and the Bondowner is not required to present the Bond for
action by the Trustee, as bond registrar, with each payment of principal on the
Bond. Payment of the interest on the Bonds shall be made by the Trustee on each
interest payment date to the person appearing on the registration books of the
City hereinafter provided for as the registered owner thereof on the fifteenth
day (whether or not a business day) of the calendar month next preceding such
interest payment date by check or draft mailed by the Trustee to such registered
owner at such owner's address as it appears on such registration books. The
Trustee is authorized to make interest payments on any Bond by internal bank
transfer or by wire transfer to an account at a commercial bank or savings
institution designated by such Bondowner and located in the continental United

Section 205. Execution and Authentication of Bonds.

(a) The Bonds shall be executed on behalf of the City by the manual or
facsimile signature of its Mayor and attested by the manual or facsimile
signature of its City Clerk, and shall have the corporate seal of the City
affixed thereto or imprinted thereon. In case any officer whose signature or
facsimile thereof appears on the Bonds shall cease to be such officer before the
delivery of such Bond, such signature or facsimile thereof shall nevertheless be
valid and sufficient for all purposes, the same as if such person had remained
in office until delivery. Any Bond may be signed by such persons as at the
actual time of the execution of such Bond shall be the proper officers to sign
such Bond although at the date of such Bond such persons may not have been such
officers.

(b) The Bonds shall have endorsed thereon a Certificate of Authentication
substantially in the form set forth in Section 403 hereof, which shall be
manually executed by the Trustee. No Bond shall be entitled to any security or
benefit under this Indenture or shall be valid or obligatory for any purposes
unless and until such Certificate of Authentication shall have been duly
executed by the Trustee. Such executed Certificate of Authentication upon any
Bond shall be conclusive evidence that such Bond have been duly authenticated
and delivered under this Indenture. The Certificate of Authentication on any
Bond shall be deemed to have been duly executed if signed by any authorized
officer or signatory of the Trustee.

Section 206. Registration, Transfer and Exchange of Bonds.

(a) The Trustee shall keep books for the registration and for the transfer
of Bonds as provided in this Indenture.

(b) The Bonds may be transferred only upon the books kept for the
registration and transfer of Bonds upon surrender thereof to the Trustee duly
endorsed for transfer or accompanied by an assignment duly executed by the
registered owner or such owner's attorney or legal representative in such form
as shall be satisfactory to the Trustee. The Series 2002 Bond has not been
registered under the Securities Act of 1933, as amended, or any state securities
law, and the Series 2002 Bond may not be transferred unless the City and the
Trustee are furnished a written legal opinion from counsel acceptable to the
City, the Trustee and the Company, to the effect that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and any applicable state securities law. The Series 2002 Bond may be transferred
to any entity controlled by, under common control with or controlling the
Company without the necessity of obtaining such an opinion. In connection with
any such transfer of the Series 2002 Bond, the City and the Trustee shall
receive an executed representation letter signed by the proposed assignee
containing substantially the same representations contained in the
representation letter delivered to the Trustee from the Owner upon the initial
issuance of the Bond. Upon any such transfer, the City shall execute and the
Trustee shall authenticate and deliver in exchange for such Series 2002 Bond a
new fully registered Bond, registered in the name of the transferee, of any
denomination or denominations authorized by this Indenture, in an aggregate
principal amount equal to the outstanding principal amount of such Bond, of the
same maturity and bearing interest at the same rate.

(c) In all cases in which Bonds shall be exchanged or transferred hereunder
the provisions of any legend restrictions on the Bonds shall be complied with
and the City shall execute and the Trustee shall authenticate and deliver at the
earliest practicable time Bonds in accordance with the provisions of this
Indenture. All Bonds surrendered in any such exchange or transfer shall
forthwith be cancelled by the Trustee. The City or the Trustee may make a
reasonable charge for every such exchange or transfer of Bonds sufficient to
reimburse it for any tax, fee or other governmental charge required to be paid
with respect to such exchange or transfer, and such charge shall be paid before
any such new Bonds shall be delivered. Neither the City nor the Trustee shall be
required to make any such exchange or transfer of

-9-



Bonds during the 15 days immediately preceding an interest payment date on the
Bonds or, in the case of any proposed redemption of Bonds, during the 15 days
immediately preceding the selection of Bonds for such redemption or after such
Bonds or any portion thereof has been selected for redemption.

Section 207. Persons Deemed Owners of Bonds. As to any Bond, the person in
whose name the same shall be registered as shown on the bond registration books
required by Section 206 hereof shall be deemed and regarded as the absolute
owner thereof for all purposes, and payment of or on account of the principal of
and interest on any such Bond shall be made only to or upon the order of the
registered owner thereof or a legal representative thereof. All such payments
shall be valid and effectual to satisfy and discharge the liability upon such
Bond, including the interest thereon, to the extent of the sum or sums so paid.

Section 208. Authorization of the Series 2002 Bond.

(a) There shall be issued and secured by this Indenture a series of Bonds
in the aggregate maximum principal amount of $125,000,000 for the purpose of
providing funds for paying the costs of the Project, which Bond shall be

redemption as hereinafter provided in Article III) and shall bear interest as

2.08(e) hereof.

(b) Before any Additional Bonds shall be issued under the provisions of
this Section, the City shall pass an ordinance authorizing the issuance of such
Additional Bond, fixing the amount thereof and describing the Bonds, if any, to

(c) Such Additional Bonds shall be dated, shall be stated to mature in such
year or years, shall bear interest at such rate or rates not exceeding the
maximum rate then permitted by law, and shall be redeemable at such times and
prices, all as may be provided by the Supplemental Indenture authorizing the

maturity or maturities, the rate or rates of interest or the provisions for
redemptions, such Additional Bonds shall be on a parity with and shall be
entitled to the same benefit and security of this Indenture as the Series 2002
Bond, and any other Additional Bonds which remain Outstanding after the issuance
of such Additional Bonds.

(d) The proceeds, excluding accrued interest, of all Additional Bonds shall
be deposited in accordance with the terms of the ordinance authorizing their
issuance, after payment or making provision for payment of all expenses incident
to such financing to be used for the sole and exclusive purposes provided in the
Supplemental Indenture authorizing the issuance of such Additional Bonds.

Section 210. Mutilated, Lost, Stolen or Destroyed Bonds. In the event any
Bonds shall become mutilated, or be lost, stolen or destroyed, the City shall
execute and the Trustee shall authenticate and deliver new Bonds of like series,
date and tenor as the Bonds mutilated lost, stolen or destroyed; provided that,
in the case of any mutilated Bonds, such mutilated Bond shall first be
surrendered to the Trustee, and in the case of any lost, stolen or destroyed
Bonds, there shall be first furnished to the City and the Trustee evidence of
such loss, theft or destruction satisfactory to the City and the Trustee,
together with indemnity satisfactory to them. In the event any such Bonds shall
have matured, instead of issuing a substitute Bond, the City may pay or
authorize the payment of the same without surrender thereof. Upon the issuance
of any substitute Bond, the City and the Trustee may require the payment of an
amount sufficient to reimburse the City and the Trustee for any tax or other
governmental charge that may be imposed in relation thereto and any other
reasonable fees and expenses incurred in connection therewith.

Section 211. Cancellation and Destruction of Bonds Upon Payment.

(a) All Bonds which have been paid or redeemed or which the Trustee has

immediately upon the payment, redemption or purchase of such Bond and the
surrender thereof to the Trustee.

correct said default or cause said default to be corrected, and shall not have

instituted by the Company within such period and diligently pursued until the
default is corrected.

operate and manage the same, and from time to time make all needful repairs and
improvements; the Trustee may lease the Project or any part thereof, in the name
and for account of the City, and collect, receive and sequester the rents,
revenues and receipts therefrom, and out of the same and any moneys received

While in possession of such property, the Trustee shall render annually to the
City and the Company a summarized statement of receipts and expenditures in
connection therewith.

proceeding to enforce the payment of the principal of and interest on the Bond
then Outstanding, and to enforce and compel the performance of the duties and
obligations of the City or the Company as herein set forth or as set forth in
the Lease and the Deed of Trust, respectively.

(b) If an Event of Default shall have occurred and be continuing, and if
requested to do so by the Owners of 25% in aggregate principal amount of Bonds
then Outstanding and indemnified as provided in subsection (l) of Section 1001
hereof, the Trustee shall be obligated to exercise such one or more of the
rights and powers conferred by this Article as the Trustee, being advised by
counsel, shall deem most expedient and in the interests of the Bondowners.

(c) All rights of action under this Indenture or under any of the Bonds may
be enforced by the Trustee without the possession of any of the Bonds or the
production thereof in any trial or other proceedings relating thereto, and any
such suit or proceeding instituted by the Trustee shall be brought in its name
as Trustee without necessity of joining as plaintiffs or defendants any Owners
of the Bonds, and any recovery of judgment shall, subject to the provisions of
Section 908 hereof, be for the equal benefit of all the Owners of the
Outstanding Bonds.

any Bond shall have any right to institute any suit, action or proceeding in
equity or at law for the enforcement of this Indenture or for the execution of

subsection (l) of Section 1001, and (d) the Trustee shall thereafter fail or
refuse to exercise the powers herein granted or to institute such action, suit
or proceeding in its own name; such notification, request and offer of indemnity
are hereby declared in every case, at the option of the Trustee, to be
conditions precedent to the execution of the powers and trusts of this
Indenture, and to any action or cause of action for the enforcement of this


-26-



Indenture, or for the appointment of a receiver or for any other remedy
hereunder, it being understood and intended that no one or more Owners of the
Bond shall have any right in any manner whatsoever to affect, disturb or

except in the manner herein provided, and that all proceedings at law or equity
shall be instituted, had and maintained in the manner herein provided and for
the equal benefit of the Owners of all Bonds then Outstanding. Nothing in this
Indenture contained shall, however, affect or impair the right of any Bondowner

protected from liabilities by insurance policies required by the Lease.

Section 908. Application of Moneys in Event of Default.

(a) All moneys received by the Trustee pursuant to any right given or
action taken under the provisions of this Article shall, after payment of the
cost and expenses of the proceedings resulting in the collection of such moneys
and of the fees, expenses, liabilities and advances incurred or made by the
Trustee (including any attorneys fees and expenses) or to be paid pursuant to
Section 903 hereof, be deposited in the Bond Fund and all moneys so deposited in
the Bond Fund shall be applied as follows:

(1) Unless the principal of all the Bonds shall have become or shall
have been declared due and payable, all such moneys shall be applied:

FIRST -- To the payment to the persons entitled thereto of all
installments of interest, if any, then due and payable on the Bonds, in the
order in which such installments of interest became due and payable, and,
if the amount available shall not be sufficient to pay in full any
particular installment, then to the payment ratably, according to the
amounts due on such installment, to the persons entitled thereto, without
any discrimination or privilege;

SECOND -- To the payment to the persons entitled thereof of the unpaid
principal of any of the Bonds which shall have become due and payable
(other than Bonds called for redemption for the payment of which moneys are
held pursuant to the provisions of this Indenture), in the order of their
due dates, and, if the amount available shall not be sufficient to pay in
full Bonds due on any particular date, together with such interest, then to
the payment, ratably, according to the amount of principal due on such
date, to the persons entitled thereto without any discrimination or
privilege.

-27-



(2) If the principal of all the Bonds shall have become due or shall
have been declared due and payable, all such moneys shall be applied to the
payment of the principal and interest, if any, then due and unpaid on all
of the Bonds, without preference or priority of principal over interest or
of interest over principal or of any installment of interest over any other
installment of interest or of any Bond over any other Bond, ratably,
according to the amounts due respectively for principal and interest, to
the person entitled thereto, without any discrimination or privilege.

(3) If the principal of all the Bonds shall have been declared due and
payable, and if such declaration shall thereafter have been rescinded and
annulled under the provisions of Section 910, then, subject to the
provisions of subsection (2) of this Section in the event that the
principal of all the Bonds shall later become due or be declared due and
payable, the moneys shall be applied in accordance with the provisions of
subsection (1) of this Section.

(b) Whenever moneys are to be applied pursuant to the provisions of this
Section, such moneys shall be applied at such times and from time to time as the
Trustee shall determine, having due regard to the amount of such moneys

be an interest payment date unless it shall deem another date more suitable)
upon which such application is to be made and upon such date interest on the
amounts of principal to be paid on such dates shall cease to accrue.

(c) Whenever all of the Bonds and interest thereon, if any, have been paid

to the Bondowners hereunder or now or hereafter existing at law or in equity or
by statute. No delay or omission to exercise any right, power or remedy accruing
upon any Event of Default shall impair any such right, power or remedy or shall
be construed to be a waiver of any such Event of Default or acquiescence
therein; every such right, power or remedy may be exercised from time to time
and as often as may be deemed expedient. In case the Trustee shall have
proceeded to enforce any right under this Indenture by the appointment of a
receiver, by entry, or otherwise, and such proceedings have been discontinued or
abandoned for any reason, or shall have been determined adversely, then and in
every such case the City, the Company, the Trustee and the Bondowners shall be
restored to their former positions and rights hereunder, and all rights,
remedies and powers of the Trustee shall continue as if no such proceedings had
been taken.

Section 910. Waivers of Events of Default. The Trustee may in its

and shall do so upon the written request of the Owners of at least 50% in
aggregate principal amount of all the Bonds then Outstanding (except for any
Event of Default hereunder as a result of any Event of Default under Section
12.1(e) of the Lease which may only be waived by the City), provided, however,
that there shall not be waived without the consent of the Owners of all the
Bonds Outstanding (a) any Event of Default in the payment of the principal of
any Outstanding Bonds when due (whether at the date of maturity or redemption
specified therein), or (b) any Event of Default in the payment when due of the
interest on any such Bond, unless prior to such waiver or rescission, all
arrears of interest, or all arrears of payments of principal when due, as the
case may be, and all reasonable expenses of the Trustee (including attorneys
fees and expenses), in connection with such default, shall have been paid or
provided for. In case of any such waiver or rescission, or in case any
proceeding taken by the Trustee on

-28-



account of any such default shall have been discontinued or abandoned or
determined adversely, then and in every such case the City, the Company, the
Trustee and the Bondowners shall be restored to their former positions, rights
and obligations hereunder, respectively, but no such waiver or rescission shall
extend to any subsequent or other default, or impair any right consequent
thereon.

ARTICLE X

THE TRUSTEE

Section 1001. Acceptance of the Trusts. The Trustee hereby accepts the
trusts imposed upon it by this Indenture, but only upon and subject to the
following express terms and conditions, and no implied covenants or obligations
shall be read into this Indenture against the Trustee:

(a) The Trustee, prior to the occurrence of an Event of Default and
after the curing of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically
set forth in this Indenture. If any Event of Default shall have occurred
and be continuing, subject to Section 1001(l) below, the Trustee shall
exercise such of the rights and powers vested in it by this Indenture, and
shall use the same degree of care and skill in their exercise, as a prudent
corporate trust department would exercise or use under the circumstances in
the conduct of its own affairs.

(b) The Trustee may execute any of the trusts or powers hereunder or
perform any duties hereunder either directly or through agents, attorneys
or receivers and shall not be responsible for any misconduct or negligence
on the part of any agent, attorney or receiver appointed or chosen by it
with due care, and the Trustee shall be entitled to act upon the opinion or
advice of counsel, who may be counsel to the City or to the Company,
concerning all matters of trust hereof and the duties hereunder, and may in
all cases pay such reasonable compensation to all such agents, attorneys
and receivers as may reasonably be employed in connection with the trusts
hereof. The Trustee shall not be responsible for any loss or damage
resulting from any action or nonaction by it taken or omitted to be taken
in good faith in reliance upon such opinion or advice of counsel addressed
to the City and the Trustee.

(c) Except as provided in the Lease and particularly Section 10.8
thereof, the Trustee shall not be responsible for any recital herein or in
the Bond (except with respect to the Certificate of Authentication of the
Trustee endorsed on the Bond), or for the recording or rerecording, filing
or refiling of this Indenture or any security agreement in connection
therewith, or for insuring the Project or collecting any insurance moneys,
or for the validity of the execution by the City of this Indenture or of
any Supplemental Indentures or instruments of further assurance, or for the
sufficiency of the security of the Bonds. The Trustee shall not be
responsible or liable for any loss suffered in connection with any
investment of funds made by it in accordance with Article VII hereof.

rights which it would have if it were not Trustee.

refraining from acting upon any ordinance, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order,
affidavit, letter, telegram or other paper or document provided for under
this Indenture believed by it to be genuine and correct and to have been
signed, presented or sent by the

proper person or persons. Any action taken by the Trustee pursuant to this
Indenture upon the request or authority or consent of any person who, at
the time of making such request or giving such authority or consent is the
Owner of any Bond, shall be conclusive and binding upon all future Owners
of the same Bond and upon Bonds issued in exchange therefor or upon
transfer or in place thereof.

sufficiency or validity of any instrument, paper or proceeding, or whenever
in the administration of this Indenture the Trustee shall deem it desirable
that a matter be proved or established prior to taking, suffering or
omitting any action hereunder, the Trustee shall be entitled to rely upon a
certificate signed by the Authorized City Representative or an Authorized
Company Representative as sufficient evidence of the facts therein
contained, and prior to the occurrence of a default of which the Trustee
has been notified as provided in subsection (h) of this Section or of which
by said subsection it is deemed to have notice, the Trustee shall also be
at liberty to accept a similar certificate to the effect that any
particular dealing, transaction or action is necessary or expedient, but
may at its discretion secure such further evidence deemed necessary or
advisable, but shall in no case be bound to secure the same.

(g) The permissive right of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty, and the Trustee shall not
be answerable for other than its negligence or willful misconduct.

(h) The Trustee shall not be required to take notice or be deemed to
have notice of any default hereunder except failure by the City to cause to
be made any of the payments to the Trustee required to be made in Article
VI hereof, unless the Trustee shall be specifically notified in writing of
such default by the City or by the Owners of at least 25% in aggregate
principal amount of all Bonds then Outstanding.

reasonable and standard security procedures, the Trustee and its duly
authorized agents, attorneys, experts, engineers, accountants and
representatives shall have the right, but shall not be required, to inspect
any and all of the Project, and all books, papers and records of the City
pertaining to the Project and the Bonds, and to take such memoranda from
and in regard thereto as may be desired. The Trustee shall treat all
proprietary information of the Company as confidential.

(j) The Trustee shall not be required to give any bond or surety in
respect to the execution of its trusts and powers hereunder or otherwise in
respect of the Project.

(k) The Trustee shall have the right, but shall not be required, to
demand, in respect of the authentication of any Bond, the withdrawal of any
cash, the release of any property, or any action whatsoever within the
purview of this Indenture, any showings, certificates, opinions, appraisals
or other information, or corporate action or evidence thereof, in addition
to that by the terms hereof required, as a condition of such action by the
Trustee deemed desirable for the purpose of establishing the right of the
City to the authentication of any Bond, the withdrawal of any cash, or the
taking of any other action by the Trustee.

(l) Before taking any action under this Indenture other than the
payments from moneys on deposit in the Construction Fund or the Bond Fund,
as provided herein, the Trustee may require that satisfactory indemnity be
furnished to it for the reimbursement of all costs and expenses to which it
may be put and to protect it against all liability which it may incur in or
by reason of

-30-



such action, except liability which is adjudicated to have resulted from
its negligence or willful misconduct by reason of any action so taken.

Section 1002. Fees, Charges and Expenses of the Trustee. The Trustee shall
be entitled to payment of and/or reimbursement for reasonable fees for its
ordinary services rendered hereunder and all advances, agent and counsel fees
and other ordinary expenses reasonably made or incurred by the Trustee in
connection with such ordinary services and, in the event that it should become
necessary that the Trustee perform extraordinary services, it shall be entitled
to reasonable extra compensation therefor and to reimbursement for reasonable
extraordinary expenses in connection therewith; provided that if such
extraordinary services or extraordinary expenses are occasioned by the neglect
or willful misconduct of the Trustee, it shall not be entitled to compensation
or reimbursement therefor. The Trustee shall be entitled to payment and
reimbursement for the reasonable fees and charges of the Trustee as Paying Agent
for the Bonds. Pursuant to the provisions of Section 5.2 of the Lease, the
Company has agreed to pay to the Trustee all reasonable fees, charges and
expenses of the Trustee under this Indenture. The Trustee agrees that the City
shall have no liability for any reasonable fees, charges and expenses of the
Trustee, and the Trustee agrees to look only to the Company for the payment of
all reasonable fees, charges and expenses of the Trustee and any Paying Agent as
provided in the Lease. Upon the occurrence of an Event of Default and during its

payment on account of principal of or interest on any Bond, upon all moneys in
its possession under any provisions hereof for the foregoing reasonable
advances, fees, costs and expenses incurred.

then the Trustee shall give written notice thereof to the last known Owners of
all Bonds then Outstanding as shown by the bond registration books required by
Section 206 to be kept at the corporate trust office of the Trustee.

Section 1004. Intervention by the Trustee. In any judicial proceeding to
which the City is a party and which, in the opinion of the Trustee and its
counsel, has a substantial bearing on the interests of Owners of the Bonds, the
Trustee may intervene on behalf of Bondowners and, subject to the provisions of
Section 1001(l) hereof, shall do so if requested in writing by the Owners of at
least 25% of the aggregate principal amount of Bonds then Outstanding.

Section 1005. Successor Trustee Upon Merger, Consolidation or Sale. With
the prior written consent of the Company, any corporation or association into
which the Trustee may be merged or converted or with or into which it may be
consolidated, or to which it may sell or transfer its corporate trust business
and assets as a whole or substantially as a whole, or any corporation or
association resulting from any merger, conversion, sale, consolidation or
transfer to which it is a party, shall be and become successor Trustee hereunder
and shall be vested with all the trusts, powers, rights, obligations, duties,
remedies, immunities and privileges hereunder as was its predecessor, without
the execution or filing of any instrument or any further act on the part of any
of the parties hereto.

Section 1006. Resignation of Trustee. The Trustee and any successor Trustee
may at any time resign from the trusts hereby created by giving 30 days' written
notice to the City, the Company and the Bondowners, and such resignation shall

successor Trustee by the Bondowners or by the City. The Trustee shall resign at
any time it determines that it has a conflict of interest (as defined in the
Trust Indenture Act of 1939), and shall, within 90 days after ascertaining that
it has a conflict of interest, or within 30 days after receiving written notice
from the City or the Company (so long as the Company is not in default under the
Lease Agreement)

-31-



that it has a conflict of interest, either eliminate such conflicting
interest or resign in the manner and with the effect specified in this
Indenture.

Section 1007. Removal of Trustee. The Trustee may be removed at any time,
with or without cause, by an instrument or concurrent instruments in writing (a)
delivered to the Trustee, the City and the Company and signed by the Owners of a
majority in aggregate principal amount of Bonds then Outstanding, or (b) so long
as no Event of Default under this Indenture or the Lease shall have occurred and
be continuing, delivered to the Trustee, the City and the Owners of the Bonds
and signed by the Company.

Section 1008. Appointment of Successor Trustee. In case the Trustee
hereunder shall resign or be removed, or shall otherwise become incapable of
acting hereunder, or in case it shall be taken under the control of any public
officer or officers or of a receiver appointed by a court, a successor Trustee
(a) reasonably acceptable to the City may be appointed by the Company (so long
as no Event of Default shall have occurred and be continuing), or (b) reasonably
acceptable to the City and the Company may be appointed by the Owners of a
majority in aggregate principal amount of Bonds then Outstanding, by an
instrument or concurrent instruments in writing; provided, nevertheless, that in
case of such vacancy, the City, by an instrument executed and signed by its
Mayor and attested by its City Clerk under its seal, may appoint a temporary
Trustee to fill such vacancy until a successor Trustee shall be appointed in the
manner above provided. Any such temporary Trustee so appointed by the City shall
hold such appointment no longer than 90 days without Company approval (so long
as no Event of Default shall have occurred and be continuing) and shall
immediately and without further acts be superseded by the successor Trustee so
appointed as provided above. Every such Trustee appointed pursuant to the
provisions of this Section shall be a trust company or bank in good standing and
qualified to accept such trust having, or whose obligations are guaranteed by a
financial institution having, a reported capital, surplus and undivided profits
of not less than $50,000,000.

Section 1009. Vesting of Trusts in Successor Trustee. Every successor
Trustee appointed hereunder shall execute, acknowledge and deliver to its
predecessor and also to the City and the Company an instrument in writing
accepting such appointment hereunder, and thereupon such successor shall,
without any further act, deed or conveyance, become fully vested with all the
trusts, powers, rights, obligations, duties, remedies, immunities and privileges
of its predecessor; but such predecessor shall, nevertheless, on the written
request of the City, execute and deliver an instrument transferring to such
successor Trustee all the trusts, powers, rights, obligations, duties, remedies,
immunities and privileges of such predecessor hereunder; every predecessor
Trustee shall deliver all securities and moneys held by it as Trustee hereunder
to its successor. Should any instrument in writing from the City be required by
any successor Trustee for more fully and certainly vesting in such successor the
trusts, powers, rights, obligations, duties, remedies, immunities and privileges
hereby vested in the predecessor, any and all such instruments in writing shall,
on request, be executed, acknowledged and delivered by the City.

Section 1010. Right of Trustee to Pay Taxes and Other Charges. In case any
tax, assessment or governmental or other charge upon, or insurance premium with
respect to, any part of the Project is not paid as required herein or in the
Lease, the Trustee may pay such tax, assessment or governmental charge or
insurance premium, without prejudice, however, to any rights of the Trustee or
the Bondowners hereunder arising in consequence of such failure; any amount at
any time so paid under this Section, with interest thereon from the date of
payment at the rate of 10% per annum, shall become an additional obligation
secured by this Indenture, and the same shall be given a preference in payment
over any payment of principal of or interest on the Bonds, and shall be paid out
of the proceeds of rents, revenues and receipts collected from the Project, if
not otherwise caused to be paid; but the Trustee shall be under no obligation to
make any such payment unless it shall have been requested to do so by the Owners
of at least 25% of the

-32-



aggregate principal amount of Bonds then Outstanding and shall have been
provided adequate funds for the purpose of such payment.

Section 1011. Trust Estate May be Vested in Co-trustee.

(a) It is the purpose of this Indenture that there shall be no
violation of any law of any jurisdiction (including particularly the State
of Missouri) denying or restricting the right of banking corporations or
associations to transact business as trustee in such jurisdiction. It is
recognized that in case of litigation under this Indenture or the Lease,
and in particular in case of the enforcement of either on default or in
case the Trustee deems that by reason of any present or future law of any
jurisdiction it may not exercise any of the powers, rights or remedies
herein granted to the Trustee, or take any other action which may be
desirable or necessary in connection therewith, it may be necessary or
desirable that the Trustee appoint an additional individual or institution
as a co-trustee or separate trustee, and the Trustee is hereby authorized
to appoint such co-trustee or separate trustee.

(b) In the event that the Trustee appoints an additional individual or
institution as a co-trustee or separate trustee (which appointment shall be
subject to the approval of the Company), each and every remedy, power,
right, claim, demand, cause of action, immunity, title, interest and lien
expressed or intended by this Indenture to be exercised by the Trustee with
respect thereto shall be exercisable by such co-trustee or separate trustee
but only to the extent necessary to enable such co-trustee or separate
trustee to exercise such powers, rights and remedies, and every covenant
and obligation necessary to the exercise thereof by such co-trustee or
separate trustee shall run to and be enforceable by either of them.

(c) Should any deed, conveyance or instrument in writing from the City
be required by the co-trustee or separate trustee so appointed by the
Trustee for more fully and certainly vesting in and confirming to such
co-trustee such properties, rights, powers, trusts, duties and obligations,
any and all such deeds, conveyances and instruments in writing shall, on
request, be executed, acknowledged and delivered by the City.

(d) In case any co-trustee or separate trustee shall die, become
incapable of acting, resign or be removed, all the properties, rights,
powers, trusts, duties and obligations of such co-trustee or separate
trustee, so far as permitted by law, shall vest in and be exercised by the
Trustee until the appointment of a successor to such co-trustee or separate
trustee.

Section 1012. Accounting. The Trustee shall render an annual accounting for
the period ending December 31 of each year to the City, the Company and to any
Bondowner requesting the same and, upon the request of the Company or the
Bondowner, a monthly accounting to the Company and the Bondowner, showing in
reasonable detail all financial transactions relating to the Trust Estate during
the accounting period and the balance in any funds or accounts created by this
Indenture as of the beginning and close of such accounting period.

Section 1013. Performance of Duties Under the Lease. The Trustee hereby
accepts and agrees to perform all duties and obligations assigned to it under
the Lease.

officer or agent of the Purchaser and delivered to the City shall be deemed a
representation and warranty by Purchaser to such parties as to the statements
made therein.

The Purchaser agrees to indemnify and hold harmless the City, the Trustee
or any member, officer, official or employee of the City or of the Trustee,
within the meaning of Section 15 of the Securities Act of 1933, as amended
(collectively, the "Indemnified Parties"), against any and all losses, claims,
damages, liabilities or expenses whatsoever caused by any violation or failure
to comply with any federal or state securities laws in connection with the
Series 2002 Bond.

In case any action shall be brought against one or more of the Indemnified
Parties based upon the foregoing indemnification and in respect of which
indemnity may be sought against the Purchaser, the Indemnified Parties shall
promptly notify the Purchaser in writing and the Purchaser shall promptly assume
the defense thereof, including the employment of counsel, the payment of all
expenses and the right to negotiate and consent to settlement. Any one or more
of the Indemnified Parties shall have the right to employ separate counsel in
any such action and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or
Indemnified Parties unless employment of such counsel has been specifically
authorized by the Purchaser or there is a conflict of interest that would
prevent counsel for the Purchaser from adequately representing both the
Purchaser and the Indemnified Party. The Purchaser shall not be liable for any
settlement of any such action effected without its consent by any of the
Indemnified Parties, but if settled with the consent of the Purchaser or if
there be a final judgment for the plaintiff in any such action against the
Purchaser or any of the Indemnified Parties, with or without the consent of the
Purchaser, the Purchaser agrees to indemnify and hold harmless the Indemnified
Parties to the extent provided herein.
