ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO
        SECURITIES OF THE ISSUER.

      On August 29, 2004, Riley Property Holdings LLC, a newly formed company
that will be majority owned by funds managed by Cerberus Capital Management, LP
and Blackacre Institutional Capital Management, LLC, agreed to acquire the
registrant through a cash merger for $63.10 per share. The transaction must,
among other things, be approved by the holders of a majority in voting power of
the outstanding shares of Common Stock and Class B Common Stock, voting together
as though they were a single class.

      In connection with the transaction, Stuart Miller, The LM Stuart Miller
Irrevocable Trust U/A 10/6/94 (of which Stuart Miller is a beneficiary), MFA
Limited Partnership and The Miller Charitable Fund, L.P. agreed (a) to acquire
approximately 20.4% of Riley Property Holdings for $150 million (to be paid by
exchanging shares of registrant for interests in Riley Property Holdings), and
(b) to vote all their shares of stock of registrant in favor of the transaction
with Riley Property Holdings and against any competing transactions.

      Because the four parties to the Voting Agreement have the power to cast
approximately 77.35% of the votes that can be cast with regard to the
transaction, that Voting Agreement will assure stockholder approval of the
transaction. However, if registrant's Board of Directors, or a Special Committee
of that Board of Directors consisting entirely of independent directors,
withdraws its recommendation that stockholders vote in favor of the transaction
or modifies that recommendation in a way that is adverse to the transaction, the
Voting Agreement will terminate unless within five days a party notifies Riley
Property Holdings that the Voting Agreement will remain in effect as to that
party.

ITEM 7. MATERIAL TO BE FILED AS EXHIBITS.

Exhibit A.  Voting Agreement dated as of August 29, 2004, among Riley Property
            Holdings LLC, Stuart Miller, The LM Stuart Miller Irrevocable Trust

            L.P.

Exhibit B.  Equity investment commitment letter dated August 29, 2004, executed
