SIMON PROPERTY GROUP AND WESTFIELD AMERICA SEEK TO ADD TWO NEW CLAIMS TO MICHIGAN LAWSUIT CONTEND THAT TCO BOARD HAS BREACHED FIDUCIARY DUTIES BY USING SHARE REPURCHASE PROGRAM TO INCREASE TAUBMAN FAMILY VOTING POWER IN CONTESTED BOARD ELECTION ALLEGE THAT APPOINTMENT OF MYRON ULLMAN III TO TCO BOARD BREACHES FIDUCIARY DUTIES AND VIOLATES TCO BY-LAWS AND MICHIGAN LAW NEW YORK, APRIL 30, 2003 - Simon Property Group, Inc. (NYSE: SPG) and Westfield America, Inc., the U.S. subsidiary of Westfield America Trust (ASX: WFA), today announced that SPG has requested permission to file a Third Amended Complaint in the United States District Court for the Eastern District of Michigan in order to challenge the latest improper actions by Taubman Centers, Inc. (NYSE: TCO). SPG and Westfield contend that the TCO Board is breaching its fiduciary duties to TCO shareholders by improperly using the TCO share repurchase program to increase the relative voting power of the Taubman family going into a contested election for board members. SPG and Westfield believe that implementation of the TCO repurchase program is an improper use of shareholder funds designed to further entrench the Taubman family, and that it contradicts TCO's public pledge of February 10, 2003, not to use the repurchase program to increase the relative voting power of the family on matters affecting the tender offer by SPG and Westfield. SPG and Westfield also believe that the TCO Board has breached its fiduciary duties to TCO shareholders by invalidly appointing its own handpicked director, Myron Ullman III, in an attempt to deprive TCO shareholders of their right to fill the seat left vacant by A. Alfred Taubman. In addition, SPG and Westfield contend that the appointment of Mr. Ullman is invalid under TCO's charter, by-laws, and Michigan law, which require that the seat to which Mr. Ullman was appointed be filled through a shareholder vote. 1 The board seat, which should have been up for election at the Company's annual meeting in May 2002, was left vacant by the resignation of Alfred Taubman in December 2001. By appointing Mr. Ullman to the board without a shareholder vote, the Company is trying to ensure that the seat will not be up for election until 2005, thereby improperly extending the three-year term of the seat previously held by Alfred Taubman into a six-year term. David Simon, CEO of SPG, and Peter Lowy, CEO of Westfield America, issued the following joint statement: "The TCO Board's recent actions are part of a continuing pattern of behavior designed to further entrench themselves at the expense of shareholders. As a result, we feel compelled once again to seek the intervention of the court in order to give shareholders the opportunity to accept our $20.00 per share all-cash offer." * * * The $20.00 per share all-cash offer for TCO shares will expire on midnight, New York City time, on May 30, 2003, unless further extended. The complete terms and conditions of the offer are set forth in the Offer to Purchase, as amended, and the related Letter of Transmittal, copies of which are on file with the SEC and available by contacting the information agent, MacKenzie Partners, Inc. at (800) 322-2885. Merrill Lynch & Co. is acting as financial advisor to SPG and Westfield America, Inc. and is the Dealer Manager for the Offer. Willkie Farr & Gallagher is acting as legal advisor to SPG and Skadden, Arps, Slate, Meagher & Flom LLP is acting as legal advisor to Westfield America, Inc. Simpson Thacher & Bartlett is acting as legal advisor to Merrill Lynch & Co. ABOUT SIMON PROPERTY GROUP Simon Property Group, Inc.
