Item 1. Security and Issuer

     This Amendment No. 1 (this "Amendment") relates to the Schedule 13D filed
on behalf of Mack-Cali Realty, L.P., a Delaware limited partnership ("Mack-Cali
LP"), and Mack-Cali Realty Corporation, a Maryland corporation ("Mack-Cali," and
collectively with Mack-Cali LP, the "Mack-Cali Reporting Persons"), with the
Securities and Exchange Commission on December 1, 2006 (the "Schedule 13D"),
relating to shares of common stock, par value $.01 per share (the "Shares"), of
Reckson Associates Realty Corp., a Maryland corporation (the "Issuer").

        Items 3, 4 and 5 of the Schedule 13D are amended and supplemented as
follows:

Item 3. Source and Amount of Funds or Other Consideration

        As explained in Item 4 below, Mack-Cali LP has ceased to be a limited
partner of Rome Acquisition Limited Partnership (the "Partnership").
Accordingly, Mack-Cali LP will not fund its capital contribution to the
Partnership.

Item 4. Purpose of Transaction

        As previously disclosed, Mack-Cali LP became a limited partner of the
Partnership on November 30, 2006 on the terms set forth in the Amendment to the
Agreement of Limited Partnership of Rome Acquisition Limited Partnership, dated
as of November 30, 2006 (the "Agreement") and deposited the amount of its
capital contribution into a segregated account at JPMorgan. Pursuant to Section
3.1 of the Agreement, Mack-Cali LP was entitled to elect, in its sole and
absolute discretion, not to become irrevocably committed to contribute such
amount to the Partnership. On December 2, 2006, Mack-Cali LP elected to cease to
be a limited partner of the Partnership and will not make its capital
contribution to the Partnership.

Item 5. Interest in Securities of the Issuer

        The Mack-Cali Reporting Persons do not own any Shares. Further, because
Mack-Cali LP is no longer a limited partner of the Partnership, the Mack-Cali
Reporting Persons may no longer be deemed to be members of a "group" with Rome,
the Macklowe Reporting Persons or the Icahn Reporting Persons (each as defined
in the Schedule 13D) and may not be deemed to beneficially own (as that term is
defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the
"Exchange Act")) all of the Shares beneficially owned by Rome, the Macklowe
Reporting Persons and the Icahn Reporting Persons. The Mack-Cali Reporting
Persons have therefore ceased to be reporting persons under Section 13(d) of the
Exchange Act.






                                    SIGNATURE

        After reasonable inquiry and to the best of each of the undersigned
knowledge and belief, each of the undersigned certifies that the information set
forth in this statement is true, complete and correct.
