ITEM 5.  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.
