Item 1.01.  Entry into a Material Definitive Agreement.

     Australian Offering and Formation of Joint Venture. Reckson Associates
Realty Corp. ("Reckson") has announced the execution of an Underwriting
Agreement relating to the offering in Australia of approximately A$263 million
(approximately US$202 million) of units in a newly-formed Reckson-sponsored
Australian listed property trust, Reckson New York Property Trust ("Reckson
NYPT"), to be traded on the Australian Stock Exchange (ASX). The Australian
offer document was lodged with the Australian Securities and Investments
Commission (ASIC) on Monday, August 15, 2005. The transaction is expected to
close and Reckson NYPT (ASX: RNY) is scheduled to begin trading on the ASX on
September 26, 2005. Reckson NYPT will be managed by Reckson Australia
Management Limited (RAML), an Australian licensed Responsible Entity which is
wholly owned by Reckson Operating Partnership, L.P. Reckson NYPT will
contribute the net proceeds of the offering in exchange for a 75% indirect
interest in a newly-formed joint venture in the United States.

     Reckson also entered into a Contribution Agreement and a Sale Agreement
pursuant to which, among other things, it will transfer 25 of its properties
at a purchase price of approximately US$563 million and containing an
aggregate of 3.4 million square feet to the joint venture in exchange for a
25% interest and approximately US$502 million in cash (inclusive of proceeds
from mortgage debt). Reckson will arrange for approximately US$320 million of
debt, including approximately US$248 million of fixed rate debt and
approximately US$72 million of floating rate debt, that will encumber the
properties transferred to the joint venture.

     Reckson will also grant the joint venture options to acquire ten
additional properties containing an aggregate of approximately 1.2 million
square feet over a two year period at a price based upon the fair market value
at the time of transfer to the joint venture. Affiliates of Reckson will
provide asset management, property management, leasing, construction and other
services to the joint venture and affiliates of Reckson will be entitled to
transaction fees and ongoing fees relating to the joint venture. Additional
information concerning this transaction is contained in Reckson's Current
Report on Form 8-K filed with the Securities and Exchange Commission on July
26, 2005.

     The offering is being made outside of the United States. Nothing herein
shall be construed as an offering of the units in Reckson NYPT. The
Underwriting Agreement, Contribution Agreement and Sale Agreement are subject
to conditions typical for transactions of this nature and, as a result, there
can be no assurance that the transactions will be completed.
