On December 31, 1997, following the receipt of all required approvals, CIPSCO Incorporated (CIPSCO) and Union Electric Company (AmerenUE) combined with the result that the common shareholders of CIPSCO and AmerenUE became the common shareholders of the Company, and the Company became the owner of 100% of the common stock of AmerenUE and CIPSCO's operating subsidiaries, Central Illinois Public Service Company (AmerenCIPS) and CIPSCO Investment Company (the Merger). For additional information about the Merger, see "Overview" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Notes 1 and 2 to the "Notes to Consolidated Financial Statements" on Pages 15, 30, and 31, respectively, of the 2000 Annual Report pages incorporated herein by reference. Ameren is a public utility holding company registered under the Public Utility Holding Company Act of 1935 (PUHCA) and does not own or operate any significant assets other than the stock of its subsidiaries. Dividends on Ameren's Common Stock are dependent on distributions to be made to it by its subsidiaries. Ameren's primary operating subsidiaries are AmerenCIPS, AmerenUE and AmerenEnergy Generating Company (Generating Company), which are engaged principally in the generation, transmission, distribution and sale of electric energy and the purchase, distribution, transportation and sale of natural gas. AmerenCIPS, a first tier subsidiary, is an Illinois corporation organized in 1902. It supplies electric and gas utility service to territories in 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 175,000 customers. AmerenUE, also a first tier subsidiary, was incorporated in Missouri in 1922, and is successor to a number of companies, the oldest of which was organized in 1881. It is the largest electric utility in the State of Missouri and supplies electric and gas service in territories in Missouri and Illinois having an estimated population of 2,600,000 within an area of approximately 24,500 square miles, including the greater St. Louis area. AmerenUE supplies electric service to about 1.1 million customers and natural gas service to about 125,000 customers. Generating Company, a wholly owned nonregulated electric generating subsidiary of AmerenEnergy Resources 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 law provides for electric utility restructuring and introduces competition into the supply of electric energy at retail in Illinois. Generating Company commenced operation on May 1, 2000 when AmerenCIPS transferred all of its generating assets to it at net book value, 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. For additional information on the Illinois Law, its impact on the Company, and the generating assets transfer, see "Electric Industry Restructuring" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Page 20 and Notes 1 and 2 to the "Notes to Consolidated Financial Statements" on Pages 30 and 31, respectively, of the 2000 Annual Report pages incorporated herein by reference. The 2000 Annual Reports on Form 10-K for AmerenCIPS and AmerenUE are available from the Company upon request. On a consolidated basis, 91.4% of the Company's 2000 operating revenues were derived from the sale of electric energy, 8.4% came from the sale of natural gas, and .2% came from other sources. Consolidated electric operating revenues as a percentage of total operating revenues were 93.3% in the years 1999 and 1998. 1 4 The Company, directly or indirectly, also owns all of the common stock of the following principal subsidiary companies: (a) CIPSCO Investment Company, a nonregulated investment company incorporated in Illinois; (b) Ameren Services Company, a Missouri corporation which provides administrative, accounting, legal, engineering, executive, and other support services to Ameren and all of its subsidiaries; (c) AmerenEnergy, Inc., a Missouri corporation which primarily serves as an energy trading and marketing agent for AmerenUE and Generating Company and provides a range of energy and risk management services to targeted customers; (d) Ameren Development Company, a nonregulated holding company incorporated in Missouri encompassing Ameren's nonregulated products and services; and (e) AmerenEnergy Resources Company (until March 2000, known as Ameren Intermediate Holding Co., Inc.), a nonregulated Illinois holding company for Generating Company and its marketing affiliate (AmerenEnergy Marketing Company) and for AmerenEnergy Fuels and Services Company which manages coal, natural gas and fuel oil purchases for the Ameren companies on a centralized basis. In addition, through AmerenCIPS and AmerenUE, the Company owns 60% of the common stock of Electric Energy, Inc., which owns and/or operates electric generation and transmission facilities in Illinois that supply electric power primarily to a uranium enrichment plant located in Paducah, Kentucky. At December 31, 2000, the Company and its subsidiaries had 7,342 employees. For information on labor agreements and other labor matters, see Note 12 to the "Notes to Consolidated Financial Statements" on Page 41 of the 2000 Annual Report pages incorporated herein by reference. For additional information regarding the Company's business operations, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Pages 15-24 and the Consolidated Financial Information on Pages 25-48 of the 2000 Annual Report pages incorporated herein by reference. CAPITAL PROGRAM AND FINANCING For information on the Company's capital program and financial needs, see "Liquidity and Capital Resources" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Page 18, and Notes 5, 7, 8, and 12 to the "Notes to Consolidated Financial Statements" on Pages 35, 36, and 41, respectively, of the 2000 Annual Report pages incorporated herein by reference. To issue first mortgage bonds and preferred stock, AmerenCIPS and AmerenUE each must comply with earnings tests contained in their respective mortgages 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 one and one-half times annual interest charges and preferred stock dividends is required under the AmerenCIPS Articles, and earnings coverage of at least two and one-half times the annual dividend on preferred stock outstanding and to be issued is required under AmerenUE's Articles. The ability to issue such securities in the future will depend on coverages at that time. Currently, each company expects to have adequate coverage ratios for anticipated requirements. Pursuant to Generating Company's indenture relating to its senior notes issued on November 1, 2000, in order to incur additional indebtedness (other than certain intercompany borrowings and debt assumptions), Generating Company must comply with a senior debt service coverage test and a senior debt to capital test, both after giving effect to the additional indebtedness contemplated. For the senior debt service coverage test, generally, the ratio of Generating Company's earnings before interest, tax, depreciation and amortization to interest and principal payments, if any, on Generating Company's senior indebtedness must be two and one-half times or greater for the most recently ended four fiscal quarters at the time of performing the test. The senior debt to capital test, generally, requires that Generating Company's ratio of senior debt to total capital must not exceed 60% as of the most recently ended fiscal quarter for which financial statements have been prepared. However, notwithstanding the two tests described above, Generating Company may incur such additional indebtedness if each of Moody's Investors Services, Inc. and Standard & Poor's Ratings Services provides a ratings reaffirmation 2 5 after giving effect to the additional indebtedness. See "Liquidity and Capital Resources" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Page 18 and Note 8 to the "Notes to Consolidated Financial Statements" on Page 36 of the 2000 Annual Report pages incorporated herein by reference for information on Generating Company's senior notes. Generating Company filed a registration statement in March 2001 (File No. 333-56594) to register the senior notes under the Securities Act of 1933, as amended, to permit an exchange offer of the senior notes. RATES For the year 2000, approximately 56%, 23%, and 21% of the Company's electric operating revenues were based on rates regulated by the Missouri Public Service Commission (MoPSC), the Illinois Commerce Commission (ICC), and the Federal Energy Regulatory Commission (FERC) of the U. S. Department of Energy, respectively. For information on rate matters in these jurisdictions, see "Results of Operations", "Rate Matters" and "Electric Industry Restructuring" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Pages 15 and 20, respectively, and Note 2 to the "Notes to Consolidated Financial Statements" on Page 31 of the 2000 Annual Report pages incorporated herein by reference. Reference is being made to "Rate Matters" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 2 (Missouri Electric) to the "Notes to Consolidated Financial Statements" on Page 31 of the 2000 Annual Report pages incorporated herein by reference, for a discussion of the Missouri electric customer credits paid or recorded by the Company under its MoPSC-approved three-year experimental alternative regulation plan covering the period July 1, 1998 through June 30, 2001 (the New Plan) and the status of efforts to extend that plan. In March 2001, the MoPSC approved a stipulation and agreement of parties regarding the credit for the plan year ended June 30, 2000. In total, the Company will pay its Missouri electric customers approximately $30 million in credits. Also on March 8, 2001, the MoPSC, in response to the February 1, 2001 filings of the Company, MoPSC staff and other parties addressing the merits of a plan extension, issued an Order authorizing the MoPSC staff to file an earnings complaint to seek a rate reduction for the Company upon expiration of the New Plan on July 1, 2001, if the MoPSC staff determines such a complaint is warranted. In addition, the Order stated that the New Plan will not be continued beyond the June 30, 2001 expiration date. The Company continues to engage in discussions with the MoPSC staff and other parties in an effort to address issues associated with the expiration of the New Plan, including the development of a new alternative regulation plan. At this time, the Company cannot predict the outcome of these discussions or the timing or amount of any future rate reductions. FUEL SUPPLY FOR ELECTRIC GENERATING FACILITIES COST OF FUELS YEAR ------------- --------------------------------------------------------------------------- 2000 1999 1998 1997 1996 ---- ---- ---- ---- ---- AMERENUE Per Million BTU - Coal 96.004 cents 100.685 cents 100.015 cents 105.600 cents 112.250 cents - Nuclear 40.269 cents 46.552 cents 48.803 cents 47.472 cents 47.499 cents - System 84.213 cents 89.833 cents 90.378 cents 92.816 cents 96.596 cents amerencips/GENERATING COMPANY* Per Million BTU - System (Coal) 123.77 cents 139.700 cents 152.738 cents 163.000 cents 171.000 cents * On May 1, 2000, all of AmerenCIPS' electric generating facilities and related fuel supply agreements were transferred to Generating Company (see "General" section above). Since that date, Generating Company has been responsible for fuel costs. Prior to that, fuel costs were the responsibility of AmerenCIPS. 3 6 OIL. The actual and prospective use of such fuel is minimal, and the Company has not experienced and does not expect to experience difficulty in obtaining adequate supplies. GAS. The combustion turbine generator equipment (CTs) which the Company placed into commercial operation in 2000 and the additional CTs that it has committed to purchase are fueled by natural gas or have dual fuel capability. Consequently, the prospective use of natural gas to supply the Company's generating facilities is expected to increase significantly. The Company does not expect to experience difficulty in obtaining adequate supplies to support the new generation facilities. The Company's natural gas procurement strategy is designed to ensure reliable and immediate delivery of natural gas 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. For additional information on the purchase of CTs and related fuel matters, see "Liquidity and Capital Resources" and "Market Risk Related to Financial Instruments and Commodity Instruments" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Pages 18 and 22, respectively, and Note 12 to the "Notes to Consolidated Financial Statements" on Page 41 of the 2000 Annual Report pages incorporated herein by reference. COAL. Because of uncertainties of supply due to potential work stoppages, delays in coal deliveries, equipment breakdowns and other factors, the Company has a policy of maintaining coal inventory consistent with its expected burn practices. Recently, the Company has experienced some delays in its coal deliveries due to certain transportation and operating constraits in the system. The Company is working closely with the transportation companies and monitoring its operating practices in order to maintain adequate levels of coal inventory for future operating purposes. NUCLEAR. The components of the nuclear fuel cycle required for nuclear generating units are as follows: (1) uranium; (2) conversion of uranium into uranium hexafluoride; (3) enrichment of uranium hexafluoride; (4) conversion of enriched uranium hexafluoride into uranium dioxide and the fabrication into nuclear fuel assemblies; and (5) disposal and/or reprocessing of spent nuclear fuel. The Company has agreements and/or inventories to fulfill its Callaway Nuclear Plant needs for uranium, enrichment, fabrication and conversion services through 2002. Additional contracts will have to 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. The Callaway Plant normally requires refueling at 18-month intervals, and refuelings are presently scheduled for the spring of 2001 and the fall of 2002. Under the Nuclear Waste Policy Act of 1982, the U. S. Department of Energy (DOE) is responsible for the permanent storage and disposal of spent nuclear fuel. DOE currently charges one mill per nuclear generated kilowatt-hour sold for future disposal of spent fuel. Electric rates charged to customers provide for recovery of such costs. DOE is not expected to have its permanent storage facility for spent fuel available until at least 2015. The Company has sufficient storage capacity at the Callaway site until 2020 and has the capability for additional storage capacity through the licensed life of the plant in 2024. The delayed availability of the DOE's disposal facility is not expected to adversely affect the continued operation of Callaway Plant. For additional information on the Company's "Fuel Supply", see "Results of Operations", "Liquidity and Capital Resources", "Market Risk Related to Financial Instruments and Commodity Instruments" and "Effects of Inflation and Changing Prices" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Pages 15, 18, 22 and 24, respectively, and Notes 1, 12 and 13 to the "Notes to Consolidated Financial Statements" on Pages 30, 41 and 43, respectively, of the 2000 Annual Report pages incorporated herein by reference. REGULATION GENERAL MATTERS. As a holding company registered with the Securities and Exchange Commission (SEC) under the PUHCA, Ameren, along with its subsidiaries, is subject to the regulatory provisions of said Act, including provisions relating to the issuance of securities, sales and acquisitions of securities and utility assets, affiliate transactions, financial reporting requirements, the services performed by Ameren Services Company and AmerenEnergy Fuels and Services Company, and the activities of 4 7 certain other subsidiaries. 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 and AmerenUE are subject to approval by the SEC under the PUHCA. Generating Company is certified by the FERC as an "exempt wholesale generator" under the Energy Policy Act of 1992 and as a result is not a "public utility company" under the PUHCA. As an exempt wholesale generator, Generating Company is exempt from most of the provisions of PUHCA that otherwise would apply to it as a subsidiary of a registered holding company. Issuance of securities by Generating Company is not subject to approval by the SEC under the PUHCA. The SEC has no jurisdiction over the sale of electricity by Generating Company to affiliates or non-affiliates. The SEC may impose limitations on Ameren in connection with its financing for the purpose of investing in exempt wholesale generators and foreign utility companies if Ameren's aggregate investment in those activities exceeds 50% of its consolidated retained earnings. At December 31, 2000, Ameren's aggregate investment in those entities was 13% of its consolidated retained earnings. AmerenCIPS and AmerenUE are subject to regulation, as applicable, by the MoPSC and the ICC as to rates, service, accounts, issuance of equity securities, issuance of debt having a maturity of more than twelve months, mergers, and various other matters. Generating Company is not subject to regulation by the ICC or the MoPSC. AmerenCIPS, AmerenUE and Generating Company 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, issuance of securities, and certain other matters. Issuance of short-term and long-term debt by Generating Company is subject to approval by the FERC. In many states, including Illinois, companies that sell electricity directly to retail customers under deregulation legislation must be registered or licensed. AmerenEnergy Marketing Company, Generating Company's marketing affiliate, has obtained "alternative retail electricity supplier" status in Illinois and is seeking comparable status in other states where retail competition is developing. For information on regulatory matters in these jurisdictions, including the current status of electric utility restructuring in Illinois and Missouri, see "Rate Matters" and "Electric Industry Restructuring" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Page 20 and Note 2 to the "Notes to Consolidated Financial Statements" on Page 31 of the 2000 Annual Report pages incorporated herein by reference. Reference is being made to "Electric Industry Restructuring" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Page 20 and Note 2 (Midwest ISO) to the "Notes to Consolidated Financial Statements" on Page 32 of the 2000 Annual Report pages incorporated herein by reference, for a discussion of Ameren's withdrawal from the electric transmission related Midwest Independent System Operator (Midwest ISO). In February 2001, in a proceeding before the FERC, the Alliance Regional Transmission Organization (Alliance RTO) and the Midwest ISO reached an agreement that enables Ameren to withdraw from the Midwest ISO and to join the Alliance RTO. This settlement agreement remains subject to FERC approval. The Company's withdrawal from the Midwest ISO also remains subject to MoPSC approval. In addition, Ameren's transfer of control and operation of its transmission assets to the Alliance RTO is subject to MoPSC and ICC approvals. At this time, the Company is unable to determine the impact that its withdrawal from the Midwest ISO and its participation in the Alliance RTO will have on its future financial condition, results of operation or liquidity. Operation of the Company's Callaway Plant is subject to regulation by the Nuclear Regulatory Commission. Its Facility Operating License for the Callaway Plant expires on October 18, 2024. The Company's Osage hydroelectric plant and its 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 5 8 February 28, 2006, and the license for the Taum Sauk Plant expires on June 30, 2010. The Company's 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. ENVIRONMENTAL MATTERS. Ameren and its subsidiaries, in certain of their 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 Ameren and its subsidiaries, 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 the companies into compliance. These companies are in material compliance with existing regulations. On December 22, 1995, a complaint was filed in the Circuit Court for the Seventh Judicial Circuit, Sangamon County, Illinois against AmerenCIPS and several other defendants. The complaint sought unspecified monetary damages and alleged that, as a result of exposure to carcinogens contained in coal tar at the AmerenCIPS Taylorville manufactured gas plant site, plaintiffs' children had suffered from a rare form of childhood cancer known as "neuroblastoma". In 1998, a jury awarded plaintiffs $3.2 million. In March 2000, the Illinois Appellate Court, on an appeal by AmerenCIPS, upheld the plaintiffs' verdict. In October 2000, the Illinois Supreme Court granted AmerenCIPS' request to review the Illinois Appellate Court's decision. The Company believes that final disposition of this matter will not have a material adverse effect on the financial position, results of operations or liquidity of the Company. On August 24, 2000, Steven and Tina Brannon sued the Company, AmerenCIPS and Generating Company in the Circuit Court of Christian County, Illinois. The suit alleges that AmerenCIPS and others were negligent in the manner in which AmerenCIPS' manufactured gas plant site was remediated in Taylorville, Illinois, therefore, wrongfully causing the death of their son. The Brannon's son was born in 1992, diagnosed with neuroblastoma in 1996, and died in 1998. The remediation occurred in 1987. Plaintiffs seek unspecified compensatory damages in excess of $50,000. The Company believes that the final resolution of this lawsuit will not have a material adverse effect on its financial position, results of operations or liquidity. On August 2, 1996, the Illinois Attorney General filed a complaint with the Illinois Pollution Control Board alleging various violations of wastewater discharge permit conditions and ground water standards at AmerenCIPS' (now Generating Company's) Hutsonville Power Station. The complaint sought monetary penalties and the award of attorney fees. In accordance with the terms of a settlement agreement with the Illinois Environmental Protection Agency and the Illinois Attorney General, Generating Company has constructed a new lined fly ash basin at the Hutsonville Power Station and intends to close the existing unlined basin. The proposed settlement has been presented to the Board for approval. The Company believes that final disposition of this matter will not have a material adverse effect on the financial position, results of operations or liquidity of the Company. For additional discussion of environmental matters, see "Liquidity and Capital Resources" in Management's Discussion and Analysis of Financial Condition and Results of Operations" on Page 18 and Note 12 to the "Notes to Consolidated Financial Statements" on Page 41 of the 2000 Annual Report pages incorporated by reference. Reference is being made to these 2000 Annual Report pages for a discussion of regulations issued by the United States Environmental Protection Agency (EPA) in July 1997 revising the National Ambient Air Quality Standards for ozone and particulate matter. The regulations had been remanded back to the EPA for review, and the EPA appealed that decision to the U.S. Supreme Court. On February 27, 2001, the U.S. Supreme Court reversed and remanded the case to the U.S. Court of Appeals for the District of Columbia for further evaluation and opinion. The Supreme Court ruled that Congress, in enacting Clean Air Act provisions that authorized the EPA to determine air quality standards, did not unconstitutionally delegate legislative power to the agency. The Supreme Court 6 9 also rejected industry arguments that the EPA should have considered implementation costs in setting air quality standards. The ruling reaffirms the EPA's authority to establish uniform air quality standards at a level that is sufficient to protect public health. However, the manner in which the EPA proposed to implement the proposed air quality standard for ozone was ruled unlawful and the Supreme Court ordered the remand of the EPA's implementation policy to the agency for further consideration. When the proposed ambient standards are ultimately enacted, such standards will require significant additional reductions in SO2 and NOx emissions from the Company's power plants. At this time, the Company is unable to predict the ultimate impact of these revised air quality standards on its future financial condition, results of operations or liquidity. INDUSTRY ISSUES The Company is facing issues common to the electric and gas utility industries which have emerged during the past several years. These issues include: the potential for more intense competition and for changing the structure of regulation; changes in the structure of the industry as a result of changes in federal and state laws, including the formation of unregulated generating entities; on-going consideration of additional changes of the industry by federal and state authorities; continually developing environmental laws, regulations and issues, including proposed new air quality standards; public concern about the siting of new facilities; proposals for demand side management programs; public concerns about nuclear decommissioning and the disposal of nuclear wastes; and global climate issues. The Company is monitoring these issues and is unable to predict at this time what impact, if any, these issues will have on its operations, financial condition, or liquidity. Also see "Electric Industry Restructuring" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Page 20 and Notes 2 and 12 to the "Notes to Consolidated Financial Statements" on Pages 31 and 41, respectively, of the 2000 Annual Report pages incorporated herein by reference. In Missouri, the Company is participating in discussions with the state legislature regarding legislation that would not restructure the electric industry, but would allow utilities to transfer generation assets to an affiliated generating company. In addition, the legislation would allow the State's largest nonresidential customers to choose their electric supplier, among other things. At this time, the Company cannot predict whether any electric industry legislation will be passed, or what the provisions of any such legislation will be. OPERATING STATISTICS The information on Pages 47 and 48 in the Company's 2000 Annual Report is incorporated herein by reference. ITEM 2. PROPERTIES. For information on the Company's principal properties, planned additions or replacements and transfers, see "Liquidity and Capital Resources" and "Electric Industry Restructuring" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Pages 18 and 20, respectively, and Notes 2 and 12 to the "Notes to Consolidated Financial Statements" on Pages 31 and 41, respectively, of the 2000 Annual Report pages incorporated herein by reference. Future plans regarding additional electric generating facilities referred to in the 2000 Annual Report pages are subject to change, including increasing or decreasing planned or installed future generating capacity, based on market conditions, regulatory approvals for additions, the Company's results of operations and financial condition, availability of financing and other factors determined by management. The Company is a member of one of the ten regional electric reliability councils organized for coordinating the planning and operation of the nation's bulk power supply - MAIN (Mid-America Interconnected Network) operating primarily in Wisconsin, Michigan, Illinois and Missouri. The 7 10 Company'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, Generating Company and AmerenCIPS. The amended joint dispatch agreement provides a basis upon which AmerenUE and Generating Company can participate in the coordinated operation of Ameren's transmission facilities with their 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.

Business - General" above). ** The Grand Tower Plant, which was a coal plant transferred to Generating Company by AmerenCIPS on May 1, 2000, is being repowered with two gas-fired combustion turbine generating units (CTs). One CT with 163,000 gross kilowatt installed capability is scheduled to go into commercial operation before the expected 2001 peak. *** Includes 649,000 of gross kilowatt installed capability of CTs placed into service in 2000 and 450,000 of gross kilowatt installed capability of CTs scheduled for service before the expected 2001 peak (in addition to the Grand Tower CT referred to above). **** Excludes gross kilowatt installed capability of generating facilities owned by Electric Energy, Inc., of which Ameren is a 60% owner. 8 11 As of December 31, 2000, AmerenCIPS owned approximately 1,900 circuit miles of electric transmission lines. AmerenCIPS operates one propane-air plant and 4,800 miles of natural gas transmission and distribution mains. As of that date, AmerenUE owned approximately 3,500 circuit miles of electric transmission lines. AmerenUE operates three propane-air plants and 2,800 miles of gas mains. Other properties of the companies include distribution lines, underground cable, office buildings, warehouses, garages and repair shops. Substantially all of the properties and plant of AmerenCIPS and AmerenUE are subject to the direct first liens of the indentures securing their first mortgage bonds. On May 1, 2000, AmerenCIPS transferred all of its generating facilities and related assets to Generating Company. As a part of this transfer, AmerenCIPS' generating property and plant were released from the lien of the indenture securing its first mortgage bonds and such property and plant are presently unencumbered. For additional information on this asset transfer, see "General" section under "Item 1. Business" herein and "Liquidity and Capital Resources" and "Electric Industry Restructuring" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Pages 18 and 20, respectively, and Note 2 to the "Notes to Consolidated Financial Statements" on Page 31 of the 2000 Annual Report pages incorporated herein by reference. Reference is being made to "Liquidity and Capital Resources" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Page 18 and Note 2 to the "Notes to Consolidated Financial Statements" on Page 31 of the 2000 Annual Report pages incorporated herein by reference, for a discussion of Ameren's plans to cause AmerenUE's Illinois electric and natural gas utility properties to be transferred to AmerenCIPS. In March 2001, Ameren decided it will no longer pursue those plans and will be taking the necessary action to withdraw its pending requests for regulatory approvals. ITEM 3. LEGAL PROCEEDINGS. The Company is 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. The Company believes that the final disposition of these proceedings will not have a material adverse effect on its financial position, results of operations or liquidity. For additional information on legal and administrative proceedings, see "Regulation" under Item 1 herein and "Liquidity and Capital Resources", "Rate Matters" and "Electric Industry Restructuring" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" on Pages 18 and 20, respectively, and Notes 2 and 12 to the "Notes to Consolidated Financial Statements" on Pages 31 and 41, respectively, of the 2000 Annual Report pages incorporated herein by reference. -------------------------------- 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, the Company is providing this cautionary statement to identify 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: the effects of regulatory actions, including changes in regulatory policy; changes in laws and other governmental actions; the impact on the Company of current regulations related to the phasing-in of the opportunity for some customers to choose alternative energy 9 12 suppliers in Illinois; the effects of increased competition in the future due to, among other things, deregulation of certain aspects of the Company's business at both the state and federal levels; the effects of withdrawal from the Midwest ISO and membership in the Alliance RTO; future market prices for fuel and purchased power, electricity, and natural gas, including the use of financial instruments; average rates for electricity in the Midwest; business and economic conditions; interest rates; weather conditions; fuel prices and availability; generation plant construction, installation and performance; 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; monetary and fiscal policies; future wages and employee benefits costs; and legal and administrative proceedings.

MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS. On October 9, 1998, the Company adopted a Shareholder Rights Plan and declared a dividend of one preferred share purchase right (a Right) for each outstanding share of common stock, par value $ .01 per share, of the Company. Each Right entitles the registered holder to purchase from the Company one one-hundredth of a share of Series A Junior Participating Preferred Stock, par value $ .01 12 15 per share, of the Company at a price of $180 per one one-hundredth of a share of such Preferred Stock, subject to adjustment. The Rights will become exercisable if someone buys 15 percent or more of the Company's common stock. In addition, if someone buys 15 percent or more of the Company's common stock, each right will entitle its holder (other than that buyer) to purchase a number of shares of the Company's common stock having a market value of twice the Right's $180 exercise price. If the Company is acquired in a merger, each Right will entitle its holder to purchase a number of the acquiring company's common shares having a market value at the time of twice the Right's exercise price. The Rights will expire on October 9, 2008. The Rights do not have voting or dividend rights, and until they become exercisable, have no dilutive effect on the per-share earnings of the Company. The Company has 4 million shares of Preferred Stock initially reserved for issuance upon exercise of the Rights. There is no Junior Participating Preferred Stock issued or outstanding. For additional information on the Shareholder Rights Plan, see Note 6 to the "Notes to Consolidated Financial Statements" on Page 35 of the 2000 Annual Report pages incorporated herein by reference.
