Report of Independent Accountants June 25, 1999 To the Board of Directors of Central Illinois Public Service Company and the Participants of the Central Illinois Public Service Company Employee Long-Term Savings Plan, IBEW No. 702 In our opinion, the accompanying statements of net assets available for benefits with fund information and the related statements of changes in net assets available for benefits with fund information present fairly, in all material respects, the net assets available for benefits of the Central Illinois Public Service Company Employee Long-Term Savings Plan, IBEW No. 702 at December 31, 1998 and 1997, and the changes in net assets available for benefits for the years then ended, in conformity with generally accepted accounting principles. These financial statements are the responsibility of the Plan's management; our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with generally accepted auditing standards which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for the opinion expressed above. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The additional information included in Schedules I and II is presented for purposes of additional analysis and is not a required part of the basic financial statements but is additional information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Pla's management. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ PricewaterhouseCoopers LLP CENTRAL ILLINOIS PUBLIC SERVICE COMPANY Employee Long-Term Savings Plan - IBEW No. 702 Statement of Net Assets Available for Benefits, with Fund Information December 31, 1998 Page 2 ________________________________________________________________________________ Ameren Common Bond Money Growth S&P 500 Retirement AIM Stock Index Market Equity Equity Preserv.

CENTRAL ILLINOIS PUBLIC SERVICE COMPANY Employee Long-Term Savings Plan - IBEW NO. 702 Notes to Financial Statements December 31, 1998 Page 10 ________________________________________________________________________________ 1. Description of the plan General The following description of the Plan provides only general information. For a more complete description of the Plan's provisions, a copy of the Plan document is available upon request from the Plan Administrator. The Central Illinois Public Service Company (the Company) is an Illinois corporation which is a wholly-owned subsidiary of Ameren Corporation (Ameren), a holding company formed upon completion of the merger between Union Electric Company and CIPSCO Incorporated (the Merger). The Company adopted the Employee Long-Term Savings Plan - IBEW No. 702 (the Plan) on January 1, 1990, to provide a systematic means by which certain eligible employees of the Company may adopt a regular savings program and secure federal income tax benefits resulting from participation in the Plan. The Plan is a defined contribution plan subject to the Employee Retirement Income Security Act of 1974 (ERISA). The Plan provides for the investment in certain funds held under the Plan for each participating employee (the Participant). A committee (the Committee) consisting of at least three persons appointed by the Company administers the Plan. The Committee has the power to adopt rules and regulations as deemed necessary or advisable to carry out the Plan in accordance with its terms. No member of the Committee who is an employee of the Company may receive any remuneration for services performed in this capacity as a member of the Committee. Merrill Lynch Trust Company of America (the Trustee) serves as trustee under terms of the Master Trust. Participation Each employee of the Company receiving regular salary or wages who is part of the IBEW Local No. 702 collective bargaining unit and who has both completed one year of service (defined as a consecutive twelve-month period beginning with his/her employment commencement date or anniversary thereof during which he/she has completed at least 1,000 hours of service) and has attained the age of 21 is eligible to become a Participant. The total number of active participants in the Plan at December 31, 1998 was approximately 566. Contributions The Plan permits a participant to make contributions to the Plan through payroll reductions from 1% up to 15% of the Participant's compensation (as defined). In order to insure compliance with applicable nondiscrimination requirements of the Internal Revenue Code, the Committee, in accordance with the Plan, has limited highly compensated participant reductions to 10%. The Tax Reform Act of 1986 limited the maximum annual amount that may be contributed by a Participant to $10,000 in 1998 CENTRAL ILLINOIS PUBLIC SERVICE COMPANY Employee Long-Term Savings Plan - IBEW NO. 702 Notes to Financial Statements December 31, 1998 Page 11 ________________________________________________________________________________ and $9,500 in 1997. The Company transfers to the Master Trust the amount designated by the Participant where it is placed in a Participant's account no less frequently than semi-monthly. The Company shall make a matching contribution equal to 15% of the amount of compensation reduction contributions, not to exceed 5% of the participant's compensation while an active participant for such payroll period. Contributions are invested in accordance with the Participant's directions in one or more of the Funds. Employees may make "qualifying rollover contributions" of amounts received as a distribution from a prior employer's plan. Vesting The amounts in a Participant's Account are fully vested at all times. Since Company contributions vest immediately, forfeitures are not applicable. Investment options Ameren Common Stock Fund - This fund invests in shares of Ameren Corporation common stock which the trustee purchases in the open market from time to time. Upon consummation of the Merger, the common stockholders of CIPSCO received 1.03 shares of Ameren Corporation common stock, par value $.01 per share, for each share of CIPSCO common stock and became stockholders of Ameren. All activity in the Common Stock Fund is reported in these financial statements as Ameren Corporation common stock activity, regardless of whether the transaction was CIPSCO or Ameren Corporation common stock. Bond Index Fund - Funds are invested in the Barclays Global Investors Government/Corporate Bond Index Fund which is a stratified sample of bonds comprising the Lehman Brothers Government/Corporate Bond Index (the Bond Index). The Bond Index is comprised primarily of U.S. Government, U.S. Agency and corporate bonds. Standard & Poor's (S&P) 500 Equity Index Fund - Funds are invested in the Merrill Lynch Equity Index Trust, a collective trust fund maintained by Merrill Lynch Trust Company. The investment objectives of the Merrill Lynch Equity Index Trust are to approximate the total return of the S&P 500 Composite Stock Index (the Equity Index). The investment strategy has two components. Ordinarily, over 90% of the assets are held as a traditional "full replication" Equity Index portfolio comprised of all, or nearly all, 500 stocks in weightings closely aligned with those of the Equity Index. The balance of the assets are held in a liquidity pool of cash equivalents (hedged by ownershi of S&P 500 Index Futures) that provide a return very close to the Equity Index, while allowing low- cost, efficient accommodation of cash flows in and out of the Merrill Lynch Equity Index Trust. Money Market Fund - Funds are invested in the Barclays Global Investors Money Market Fund for Employee Benefit Trusts, which provides for investment and reinvestment in a variety of money market instruments, including but not limited to CENTRAL ILLINOIS PUBLIC SERVICE COMPANY Employee Long-Term Savings Plan - IBEW NO. 702 Notes to Financial Statements December 31, 1998 Page 12 ________________________________________________________________________________ U.S. government and agency securities, bank obligations such as certificates of deposit, banker's acceptances and fixed-time deposits, short-term commercial debt instruments such as commercial paper, unsecured loan participation or variable rate demand notes and repurchase agreements. Growth Equity Fund - Funds are invested in a separately managed portfolio consisting primarily of equity securities, or securities convertible into common stocks. A portion of the portfolio may be invested in cash equivalents. The portfolio is managed by Merrill Lynch Asset Management. Merrill Lynch Retirement Preservation Trust - Funds are invested primarily in U.S. government and agency securities, guaranteed investment contracts issued generally by insurance carriers and banks, and high-quality money market instruments. This Fund is a collective trust fund maintained by Merrill Lynch Trust Company. AIM Value Fund - Class A Shares - Funds are invested primarily in equity securities that are judged by the manager to be undervalued. The AIM Value Fund invests primarily in common stocks, convertible bonds and convertible preferred stocks, but also may invest in preferred stocks and other debt securities. Merrill Lynch Global Allocation Fund - Class A Shares - This fund varies the mix of investments in United States and foreign equity, debt and money market securities based upon the manager's evaluation of changing market and economic trends. Merrill Lynch Capital Fund - This fund has a fully managed investment policy utilizing equity, debt and convertible securities. Consistent with policy, the Capital Fund's portfolio may, at any given time, be invested substantially in equity securities (stocks), corporate bonds, or money market securities. It is the expectation of the investment manager that over longer periods, a major portion of the Capital Fund's portfolio will consist of equity securities of larger-market capitalization companies. Participant Loan Fund - This fund consists of amounts loaned to participants as provided for in the Plan. Plan Withdrawals/Loans No withdrawals from a Participant's account are permitted while the Participant continues to be employed by the Company except that, upon compliance with the provisions of the Plan, one withdrawal may be made each year in limited cases of financial hardship. In addition, Participants may make withdrawals of their rollover contributions and earnings thereon. Upon application of a Participant and payment of a loan application fee, the Committee may, in compliance with the Plan, direct the Trustee to make a loan to the Participant CENTRAL ILLINOIS PUBLIC SERVICE COMPANY Employee Long-Term Savings Plan - IBEW NO. 702 Notes to Financial Statements December 31, 1998 Page 13 ________________________________________________________________________________ from the Participant's account upon such terms as the Committee shall specify. Participants' loans are maintained in the Participant Loan Fund. Distributions Upon termination of employment for any reason, a Participant will be entitled to receive the balance in the Participant's account less the unpaid amount of any outstanding loan (including accrued interest). Generally, distributions will be made in a lump sum; however, in certain circumstances a Participant may also elect to receive his/her distribution in installments. Certain distributions may be deferred until a participant reaches age 70 1/2, dies, or requests an earlier distribution (whichever occurs first). Amounts that have been requested for withdrawal by Participants, but have not yet been distributed by the Plan, are included in net assets available for benefits. There were no amounts requested for withdrawal by Participants, but not yet distributed by the Plan as of December 31, 1998 or 1997. Plan termination The Company has a right to terminate the Plan at any time subject to the provisions of ERISA. Upon termination, the Trustee will distribute assets remaining in the Trust Fund with the exception that, except in certain specified situations, no distributions shall be made until a participant attains age 59 1/2. 2. Summary of significant accounting policies Basis of accounting The financial statements of the Plan are prepared on the accrual basis of accounting. Use of estimates The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of changes in net assets available for benefits during the reporting period. Actual results could differ from those estimates. Pending settlements Pending settlements represent accrued income from sales transactions for which the trade date is prior to December 31 and the settlement date is subsequent to December 31. Payroll withholdings Payroll withholdings represent accrued contributions and employee loan repayments that are owed to the Plan as of December 31. CENTRAL ILLINOIS PUBLIC SERVICE COMPANY Employee Long-Term Savings Plan - IBEW NO. 702 Notes to Financial Statements December 31, 1998 Page 14 ________________________________________________________________________________ Investments All investments are presented at fair value as of December 31, 1998 and 1997. The fair value of the Ameren Common Stock Fund was determined using year-end published market prices. Investments in equity securities and bonds are valued at net asset market value including accrued income on the last business day of each year. Investments in the Money Market Fund and Merrill Lynch Retirement Preservation Trust are valued at cost plus accrued income, which approximates market. Participant loans are valued at cost which approximates fair market value. Income Interest income is recorded on the accrual basis. Dividend income is recorded on the ex-dividend date. Gains and losses on security transactions are recorded on the trade date. Net unrealized appreciation or depreciation for the year is reflected in Net appreciation (depreciation) of investments on the Statement of Changes in Net Assets Available for Benefits. Expenses In general, expenses to administer the Plan, including fees and expenses of the Trustee, are paid by the Company, except as provided for in the Plan. All transaction fees of an investment fund are paid from the assets of that investment fund. Benefit payments Benefit payments are recorded when paid.

Federal income tax status The Plan is intended to qualify as a deferred compensation plan under sections 401 (a) and 401 (k) of the Internal Revenue Code of 1986. Qualification of the Plan means that a Participant will not be subject to federal income taxes on amounts contributed to the Participant's account, or the earnings or appreciation thereon, until such amounts either are withdrawn by the Participant or are distributed to the Participant or a beneficiary in the event of the Participant's death. Payroll reduction contributions to a Participant's account reduce the gross income of the Participant for federal income tax purposes to the extent of the contributions. The Company received a favorable determination letter from the Internal Revenue Service dated July 29, 1996, concerning the qualification of the Plan under federal income tax regulations. In addition, the Company also received a favorable determination letter from the Internal Revenue Service dated December 8, 1986, concerning qualification of the Master Long-Term Savings Trust under federal income tax regulations. Management believes that the Plan is currently designed and is being operated in compliance with requirements of the Internal Revenue Code and that the Plan is tax exempt as of the financial statement date. Discussions of the federal income tax consequences of the Plans, including consequences on distributions of Participant's account, are contained in the Company's Employee Long-Term Savings Plan Summary Plan Description and Information Statement (dated June 27, 1995).
