ITEM 5. INTEREST IN SECURITIES OF 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, 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 Leslie Saiontz
Irrevocable Trust u/a 10/6/94. Therefore, for purposes of Section 13 under the
Securities Exchange Act of 1934, as amended, (i) the Partnership is the
beneficial owner, with shared voting and dispositive power, with regard to a
total of 7,188,631 shares of common stock of the Company, (ii) the Fund is the
beneficial owner, with shared voting and dispositive power, with regard to a
total of 1,449,200 shares of common stock of the Company, and (iii) each of the
Corporation and Marital Trust I is the beneficial owner, with shared voting and
dispositive power, with regard to a total of 8,637,831 shares of common stock of
the Company. Stuart Miller, who also is the beneficial owner of those 8,637,831
shares of common stock of the Company, has reported his ownership on a separate
Schedule 13D.

      Giving effect to the conversion into common stock of all the shares of
Class B Common Stock beneficially owned, respectively, by the Partnership, the
Fund, the Corporation and Marital Trust I, 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), (i) the
shares of common stock of which the Partnership is the beneficial owner
constitute 26.5% of the outstanding shares of common stock, (ii) the shares of
common stock of which the Fund is the beneficial owner constitute 6.8% of the
outstanding shares of common stock, and (iii) the shares of common stock of
which each of the Corporation and Marital Trust I is the beneficial owner
constitute 30.2% of the outstanding shares of common stock.

      Each share of Class B Common Stock entitles the holder to cast 10 votes,
while each share of common stock entitles the holder to cast one vote.
Therefore, the 8,637,831 shares of Class B Common Stock with regard to which the
Corporation and Marital Trust I have shared voting power entitles the holder to
cast a total of 86,378,310 votes, which is 73.4% of all the votes that may be
cast at a meeting of the Company's stockholders.
