INTEREST IN SECURITIES OF THE ISSUER. Item 5 is amended by adding at the end of the text responding to paragraphs (a) and (b) the following: On April 26, 2004 Stuart Miller owned 409,833 shares of common stock (including 210,000 restricted shares and 83 shares he held through the Company's savings plan) and 100,000 shares of Class B Common Stock, and held options to purchase 199,855 shares of common stock, of which options to purchase 87,913 shares were exercisable or would become exercisable within 60 days. On April 26, 2004, the Partnership transferred 333,333 shares of Class B common stock to The LM Stuart Miller Irrevocable Trust u/a 10/6/94 and an additional 333,333 shares of Class B common stock to The LM Leslie Saiontz Irrevocable Trust u/a 10/6/94. This transaction reduced the number of shares Stuart Miller was the beneficial owner of through MFA Limited Partnership by 666,666 shares but made him the beneficial owner of 333,333 additional shares through The LM Stuart Miller Irrevocable Trust u/a 10/6/94, reducing the total number of shares of common stock of which Stuart Miller was the beneficial owner to 9,568,910 shares. Giving effect to the conversion into common stock of all the shares of Class B Common Stock held by Stuart Miller or of which he has the sole power to direct the vote and the disposition and the exercise of all the options held by Stuart Miller which were exercisable on April 26, 2004, or would become exercisable within 60 days after that, and based upon the information as to outstanding shares contained in the Company's Quarterly Report on Form 10-Q for the quarter ended February 29, 2004 (19,952,871 shares of common stock), the shares of common stock of which Stuart Miller is the beneficial owner constitute 32.9% of the outstanding shares of common stock. 3 SIGNATURES After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
