SECURITY AND ISSUER. This statement relates to the following series of preferred stock ("Preferred Stock") of Illinois Power Company, an Illinois corporation ("IPC"): o 4.08% Cumulative Preferred Stock, par value $50 per share, CUSIP No. 452092-20-8 (the "4.08% Series"); o 4.20% Cumulative Preferred Stock, par value $50 per share, CUSIP No. 452092-30-7 (the "4.20% Series"); o 4.26% Cumulative Preferred Stock, par value $50 per share, CUSIP No. 452092-40-6 (the "4.26% Series"); o 4.42% Cumulative Preferred Stock, par value $50 per share, CUSIP No. 452092-50-5 (the "4.42% Series"); o 4.75% Cumulative Preferred Stock, par value $50 per share, CUSIP No. 452092-60-4 (the "4.75% Series"); and o 7.75% Cumulative Preferred Stock, par value $50 per share, CUSIP No. 452092-79-4 (the "7.75% Series").

Pursuant to Rule 13d-1(k)(1) of the Securities Exchange Act of 1934, as amended, this statement is filed on behalf of Dynegy Inc. and Illinova Corporation. DYNEGY INC. (a) NAME: Dynegy Inc., an Illinois corporation ("Dynegy"), is one of the world's leading energy merchants.

All such directors and executive officers are citizens of the United States. ILLINOVA CORPORATION (a) NAME.

Illinova owns all the outstanding shares of IPC's common stock. (b) ADDRESS OF PRINCIPAL BUSINESS AND PRINCIPAL OFFICE: The address of Illinova's principal business and principal office is 500 South 27th Street, Decatur, Illinois 62521-2200. (c) PRESENT PRINCIPAL OCCUPATION: Not applicable. (d) CRIMINAL PROCEEDINGS: None. (e) CIVIL PROCEEDINGS INVOLVING SECURITIES LAW VIOLATIONS: None. See Exhibit "A" for information concerning the executive officers and directors of Illinova. None of such persons, during the past five years, has been convicted in a criminal proceeding, excluding traffic violations or similar misdemeanors. Further, none of such persons, during the last five years, has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction where as a result of such proceeding such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. All such directors and executive officers are citizens of the United States. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. The shares of Preferred Stock owned by Dynegy and Illinova (the "Shares") were purchased by Illinova in connection with the offer by Illinova to purchase, for cash, any and all outstanding shares of Preferred Stock (the "Tender Offer"). Concurrently with Illinova's tender offer, IPC's board of directors solicited the written consent of holders of the Preferred Stock to amend IPC's articles of incorporation to eliminate a provision that restricts IPC's ability to issue or assume unsecured debt (the "Consent Solicitation"). The Tender Offer and Consent Solicitation were commenced on February 25, 2002 and completed on March 28, 2002. The total funding (excluding fees and other expenses) required to purchase the Shares was as follows: SERIES SHARES PURCHASED PRICE PER SHARE TOTAL PURCHASE PRICE ------ ---------------- --------------- -------------------- 4.08% Series 134,638 $35.56 $4,787,727.28 4.20% Series 96,448 $36.63 $3,532,890.24 4.26% Series 71,037 $37.17 $2,640,445.29 4.42% Series 69,809 $38.61 $2,695,325.49 4.75% Series 108,311 $41.11 $4,452,665.21 7.75% Series 182,681 $52.00 $9,499,412.00 (Page 5 of 9) Illinova obtained the funds used to purchase the Shares from Dynegy in the form of an unsecured intercompany loan. Under the intercompany loan agreement, dated as of February 25, 2002, Dynegy agreed to provide Illinova a two-year unsecured loan of up to $37,046,427 to provide Illinova with funds to acquire Preferred Stock in connection with the Tender Offer, including any related fees and expenses. The loan bears interest at an approximate rate of 7.5% per year, payable semiannually on April 1 and October 1, and matures on February 25, 2004. Dynegy funded the intercompany loan by using its working capital. ITEM 4. PURPOSE OF TRANSACTION. Illinova purchased the Shares because it believed that its purchase of Preferred Stock in connection with the Tender Offer, in conjunction with the approval of the proposed amendment pursuant to the Consent Solicitation, represented an attractive opportunity that would benefit Illinova and IPC. The approval of the proposed amendment provides IPC with the flexibility to obtain financing on terms more advantageous to IPC than would otherwise be the case, which indirectly benefits Illinova as the holder of all of IPC's common stock. Illinova believed that its purchase of the Preferred Stock in connection with the Tender Offer facilitated the success of the Consent Solicitation. Illinova also believed that market conditions had resulted in a valuation of the Preferred Stock that, being lower than the redemption price, represented an advantageous opportunity for Illinova to offer to purchase shares of the Preferred Stock. Illinova or Dynegy may purchase any shares of Preferred Stock that remain outstanding through privately negotiated transactions, open market purchases, another tender offer or otherwise, on such terms and at such prices as they may determine from time to time. The terms of subsequent purchases or offers could differ from those of the Tender Offer, and may be more or less favorable to the holders of shares than the terms in the Tender Offer. Any possible future purchases of shares of Preferred Stock by Illinova or Dynegy will depend on many factors, including the market price of the shares of the Preferred Stock, their business and financial position, alternative investment opportunities available to them, legal restrictions on their ability to purchase shares of the Preferred Stock and general economic and market conditions. As a result of Illinova's purchase of the Shares, the series of Preferred Stock that are listed on the NYSE (which are all series other than the 7.75% Series) (the "NYSE Listed Series") no longer meet the requirements for listing on the NYSE. The NYSE has commenced the delisting process for such series. Once such series of Preferred Stock are delisted by the NYSE, it is possible that such series, together with the 7.75% Series, would continue to trade in the over-the-counter market and that price quotations would be reported by the National Association of Securities Dealers, Inc., or NASD, (Page 6 of 9) through NASDAQ or by other sources. The extent of the public market for each series of Preferred Stock and the availability of price quotations would depend on such factors as the number of shareholders remaining at such time, the interest in maintaining a market in the given series of Preferred Stock on the part of securities firms, the possible termination of registration under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), as described below, and other factors. As a result of the NYSE delisting the NYSE Listed Series, the NYSE Listed Series may no longer constitute "margin securites" under the regulations of the Board of Governors of the Federal Reserve System and brokers may no longer be able to use shares of such series as collateral for loans. Each series of Preferred Stock is currently registered under the Exchange Act. Such registration may be terminated upon application by IPC to the SEC if there are fewer than 300 record holders and the series is not listed on a national securities exchange. As discussed above, as a result of Illinova's purchase of the Shares, the NYSE has commenced the delisting process with respect to the the NYSE Listed Series. Termination of such registration will make certain provisions of the Exchange Act, such as the requirements of Rule 13e-3 thereunder with respect to "going private" transactions, no longer applicable to such series of Preferred Stock. If IPC has other classes of securities listed on the NYSE and registered under the Exchange Act, termination of the Exchange Act registration of a series of Preferred Stock would not affect IPC's obligation to file annual and quarterly reports and special reports, proxy statements and other information with the SEC pursuant to the Exchange Act's reporting requirements. If at some future time IPC were to retire or otherwise terminate the Exchange Act registration of all classes of its securities, IPC would have no obligation to continue filing reports with the SEC. ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. (a) See Items 11 and 13 of the cover pages, which are incorporated herein by this reference. (b) See Items 7, 8, 9 and 10 of the cover pages and Item 2 above, which are incorporated herein by this reference. (c) See Items 3 and 4 above, which are incorporated herein by this reference. (d) All persons known to have the right to receive or the power to direct the dividends from, or the proceeds from the sale of, the securities described in this Item 5 are described in this statement. (e) Not applicable. (Page 7 of 9) ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. Illinova is a wholly-owned subsidiary of Dynegy and owns all the outstanding shares of IPC's common stock. Except as described in this statement, neither Illinova, Dynegy, nor, to the knowledge of Illinova and Dynegy, any of the persons listed in Exhibit A, has any contract, arrangement, understanding or relationship (legal or otherwise) with any person with respect to any securities of IPC (including, but not limited to, transfer or voting of any of such securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies). IPC declared and paid common stock dividends of $100 million on March 2, 2001 and a special common stock dividend of $500,000 on March 28, 2002 to Illinova in accordance with IPC's articles of incorporation, the Illinois Public Utilities Act and the Federal Power Act. Effective October 1, 1999, IPC transferred its wholly owned fossil generating assets and other generation-related assets and liabilities at net book value to Illinova in exchange for an unsecured note in the amount of approximately $2.8 billion. The fossil generating assets were subsequently contributed by Illinova to its subsidiary, Illinova Power Marketing Inc., which was later renamed Dynegy Midwest Generation. Effective August 31, 2001, approximately $9 million of additional fossil generation-related assets were transferred to Illinova, and the amount outstanding under the unsecured note was increased accordingly. The note matures on September 30, 2009 and bears interest at an annual rate of 7.5%. At September 30, 2001, principal and accrued interest outstanding under the note were approximately $2.3 billion and $85 million, respectively. ITEM 7. MATERIAL TO BE FILED AS EXHIBITS.
