This Amendment No. 21 ("Amendment No. 21") is filed by Security Capital Group Incorporated, a Maryland corporation ("Security Capital Group"), SC Capital Incorporated, a Nevada corporation ("SC Capital") and a wholly owned subsidiary of Security Capital Group, SC Realty Incorporated, a Nevada corporation ("SC-Realty") and a wholly owned subsidiary of SC Capital, Security Capital Operations Incorporated, a Maryland corporation ("Operations") and a wholly owned subsidiary of SC-Realty, Security Capital Shopping Mall Business Trust, a Maryland real estate investment trust and a subsidiary of Operations (f/k/a Midwest Mixed-Use Realty Investors Trust) ("SC Shopping Mall Business Trust" and, together with Security Capital Group, "Security Capital"), General Electric Company, a New York corporation ("GE"), General Electric Capital Services, Inc., a Delaware corporation ("GECS") and a wholly owned subsidiary of GE, General Electric Capital Corporation, a Delaware corporation ("GECC") and a wholly owned subsidiary of GECS, and GE Capital International Holdings Corporation, a Delaware corporation ("GE Holdings" and, together with GE, GECS, GECC, Security Capital Group, SC Capital, SC-Realty, Operations and SC Shopping Mall Business Trust, the "Reporting Persons") and a wholly owned subsidiary of GECC and the parent corporation of Security Capital Group. This Amendment No. 21 amends the Schedule 13D originally filed by Security Capital U.S. Realty and Security Capital Holdings S.A. on June 21, 1996 (as previously amended, the "Schedule 13D"). This Amendment No. 21 relates to shares of common stock, par value $0.01 per share ("Common Stock"), of Regency Centers Corporation, a Florida corporation (f/k/a Regency Realty Corporation) ("Regency"). Capitalized terms used herein without definition shall have the meanings ascribed thereto in the Schedule 13D, as amended. Item 4. PURPOSE OF TRANSACTION Item 4 is hereby amended and supplemented as follows: As previously reported, on June 18, 2003, Security Capital entered into forward sales transactions with respect to 20,000,000 shares of Common Stock, representing all of the shares of Common Stock held of record by SC Shopping Mall Business Trust. Those forward sales contracts became effective on June 24, 2003. On September 25, 2003, Security Capital settled under its previously reported forward contract with Merrill Lynch International (the "ML Forward Contract"). In accordance with the terms of the ML Forward Contract, Security Capital delivered 3,906,667 shares of Common Stock, representing all of the shares of Common Stock subject to the ML Forward Contract, to Merrill Lynch International in exchange for a cash payment of approximately $30.68 per share (which is equal to $31.1355 per share of Common Stock, plus interest and minus the amount of dividends paid on the Common Stock with record dates between June 18, 2003 and the settlement date (plus interest on those dividends)). On September 26, 2003, Security Capital settled under its previously reported forward contract with Wachovia Bank, National Association (the "Wachovia Forward Contract"). In accordance with the terms of the Wachovia Forward Contract, Security Capital delivered 3,906,666 shares of Common Stock, representing all of the shares of Common Stock 11

subject to the Wachovia Forward Contract, to Wachovia Bank, National Association in exchange for a cash payment of approximately $30.68 per share (which is equal to $31.1355 per share of Common Stock, plus interest and minus the amount of dividends paid on the Common Stock with record dates between June 18, 2003 and the settlement date (plus interest on those dividends)). Upon settlement of Security Capital's remaining three previously reported forward sales contracts, which provide for settlement at various times during the first half of 2004, or earlier at the election of Security Capital, Security Capital will no longer own any shares of Common Stock, unless Security Capital elects to settle one or more of the forward contracts in cash rather than by delivery of shares of Common Stock. If Security Capital does not dispose of all of its shares pursuant to the remaining three previously reported forward contracts, the Reporting Persons will continue to review their investment in the Common Stock and evaluate their plans and intentions as previously described in this Schedule 13D (including, without limitation, Amendment No. 13 hereto). The Reporting Persons reserve the right, based on all relevant factors, and consistent with their contractual obligations, to change their investment intent with respect to Regency at any time in the future, to dispose of all or a portion of their remaining holdings of Common Stock, or to change their intention with respect to any or all of the matters referred to in this Schedule 13D. Any action or discussions taken in such connection will be subject to and conducted in accordance with all applicable legal rules and contractual agreements to which the Reporting Persons are subject or which otherwise apply to the purchase or sale of Common Stock or the Reporting Persons' investment in Regency. Item 5. INTEREST IN SECURITIES OF THE ISSUER As described in Item 4 above, on September 25, 2003 and September 26, 2003, Security Capital disposed of 3,906,667 and 3,906,666 shares of Common Stock, respectively, pursuant to the transactions described in Item 4. Accordingly, the aggregate number of shares that the Reporting Persons continue to beneficially own, with sole voting power and dispositive power, is 12,186,667, all of which are held of record by SC Shopping Mall Business Trust. As previously reported, pursuant to the Agreement Relating to Disposition of Shares, Security Capital has agreed to will vote any shares of Common Stock that are subject to forward contracts and over which it has voting power in the same proportion as shares are voted by other shareholders of Regency. Item 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER The descriptions of the contracts, arrangements, understandings and relationships described above in the response to Item 4 are incorporated into this Item. 12
