Security and Issuer This statement on Schedule 13D relates to the Common Stock, par value $.01 per share (the "Shares"), of Reckson Associates Realty Corp., a Maryland corporation (the "Issuer"). The principal executive offices of the Issuer are located at 625 Reckson Plaza, Uniondale, New York 11556. This statement is being filed by Mack-Cali Realty, L.P., a Delaware limited partnership ("Mack-Cali LP") and Mack-Cali Realty Corporation, a Maryland corporation ("Mack-Cali", and collectively, the "Mack-Cali Reporting Persons") solely as a result of the admission on November 30, 2006 of Mack-Cali LP as a limited partner in the Rome Acquisition Limited Partnership ("Rome") on the terms set forth in the Amendment to the Agreement of Limited Partnership of Rome, dated as of November 30, 2006 (the "Partnership Agreement Amendment"). The Mack-Cali Reporting Persons do not own any Shares, but may, as a limited partner of Rome, be deemed members of a "group" within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Act"), with Rome and with (A) WH Rome Partners LLC, a Delaware limited liability company ("WH LLC"), WH Rome Inc., a New York corporation and the managing member of WH LLC ("WH Corporation"), and Harry Macklowe and William S. Macklowe (collectively, the "Macklowe Reporting Persons"), and (B) High River Limited Partnership, a Delaware limited partnership ("High River"), Hopper Investments LLC, a Delaware limited liability company ("Hopper"), Barberry Corp., a Delaware corporation ("Barberry"), Icahn Partners Master Fund LP, a Cayman Islands exempted limited partnership ("Icahn Master"), Icahn Offshore LP, a Delaware limited partnership ("Icahn Offshore"), CCI Offshore Corp., a Delaware corporation ("CCI Offshore"), Icahn Partners LP, a Delaware limited partnership ("Icahn Partners"), Icahn Onshore LP, a Delaware limited partnership ("Icahn Onshore"), CCI Onshore Corp., a Delaware corporation (" CCI Onshore"), Starfire Holding Corporation, a Delaware corporation ("Starfire"), Highcrest Investors Corp., a Delaware corporation ("Highcrest"), Buffalo Investors Corp., a New York corporation ("Buffalo"), Meadow Star LLC, a Delaware limited liability company ("Meadow Star"), Meadow Star Partner LLC, a Delaware limited liability company ("Meadow Partner") and Carl C. Icahn (collectively, the "Icahn Reporting Persons"). As such, the group may be deemed to beneficially own (as that term is defined in Rule 13d-3 under the Act) all of the Shares beneficially owned by Rome, the Icahn Reporting Persons and the Macklowe Reporting Persons. Nothing contained herein shall be deemed to be an admission by any of the Mack-Cali Reporting Persons that they are the beneficial owners of Shares beneficially owned by Rome or any of the Icahn Reporting Persons or the Macklowe Reporting Persons, and the Mack-Cali Reporting Persons disclaim any such beneficial ownership. Item 2. Identity and Background The reporting persons are the Mack-Cali Reporting Persons. The directors and executive officers of the Mack-Cali Reporting Persons are set forth on Schedule A hereto. The principal business address of each of Mack-Cali LP and Mack-Cali is 343 Thornall Street, Edison, New Jersey 08837-2206. Mack-Cali is a fully-integrated, self-administered and self-managed real estate investment trust ("REIT"). Mack-Cali is the sole general partner of, and conducts substantially all of its business through, Mack-Cali LP. Mack-Cali LP owns and operates a real estate portfolio comprised predominantly of Class A office and office/flex properties located primarily in the Northeast. During the last five years, none of the Mack-Cali Reporting Persons and, to the knowledge of the Mack-Cali Reporting Persons, none of the executive officers, directors, control persons or members of the Mack-Cali Reporting Persons, as applicable, (i) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activity subject to, federal or state securities laws or finding any violations with respect to such laws. Mack-Cali is a Maryland corporation. Mack-Cali LP is a Delaware limited partnership. Item 3. Source and Amount of Funds or Other Consideration On November 29, 2006, Mack-Cali LP entered into a Term Loan Agreement (the "Term Loan Agreement") with JPMorgan Chase Bank, N.A. ("JPMorgan") as administrative agent for the lenders party thereto. The Term Loan Agreement, which is guaranteed by Mack-Cali, provides for loans of up to $350 million to Mack-Cali LP at an interest rate equal to either (i) the higher of JPMorgan's prime rate or the Federal Funds rate plus 50 basis points plus an applicable margin (the "Applicable Margin") of between 50 and 112.5 basis points (the "Alternate Base Rate"), or (ii) the LIBOR Rate plus the Applicable Margin. The Applicable Margin is subject to adjustment, on a sliding scale, based upon the Mack-Cali LP's unsecured debt ratings. The interest rate on outstanding borrowings under the Term Loan Agreement as of November 30, 2006 was based on the Alternate Base Rate and was 8.25%. The Term Loan Agreement matures on May 29, 2007, with an extension option to November 29, 2007, which would require a payment of 5 basis points of the then borrowing capacity of the Term Loan Agreement upon exercise. As of November 30, 2006, Mack-Cali LP has drawn $150 million from the Term Loan Agreement and an additional $250 million from its existing unsecured revolving credit facility (the "Revolving Credit Facility"), which funds are expected to be used to fund Mack-Cali LP's $400 million capital contribution to Rome as described under Item 4 of this Schedule 13D. The Revolving Credit Facility has a capacity of $600 million (expandable to $800 million) with a group of 23 lenders, and JPMorgan as administrative agent. The interest rate on the $250 million drawn from the Revolving Credit Facility is currently based on the Alternative Base Rate, which as of November 30, 2006 was 8.25%. The Revolving Credit Facility matures in November 2009, with an extension option of one year, which would require a payment of 25 basis points of the then borrowing capacity of the Revolving Credit Facility upon exercise. Item 4. Purpose of Transaction On November 30, 2006, Meadow Star, WH LLC, and Mack-Cali LP entered into the Partnership Agreement Amendment pursuant to which Mack-Cali LP was admitted to Rome as a limited partner on the terms set forth therein. Copies of the Partnership Agreement and the Partnership Agreement Amendment are filed herewith as exhibits and incorporated herein by reference. Prior to admitting Mack-Cali LP as a limited partner on the terms set forth in the Partnership Agreement Amendment, Rome sent letters to the Issuer in which Rome proposed to acquire all of the Shares (and units of Reckson Operating Partnership) for $49 per share in cash (the "Proposal"), subject to certain conditions, including satisfactory completion of due diligence. On November 29, 2006, Mack-Cali LP deposited into a segregated account at JPMorgan cash in the amount of $400 million. Pursuant to the terms and conditions of the Partnership Agreement Amendment, Mack-Cali LP will fund Rome with $400 million on December 4, 2006; provided, however, that Mack-Cali LP may elect at any time prior to 11:59 p.m. on December 2, 2006, in its sole and absolute discretion and for any reason, including, without limitation, its evaluation of the Issuer based on its due diligence review of the Issuer, not to become irrevocably committed to contribute such amount to Rome, in which case Mack-Cali LP shall cease to be a limited partner of Rome. Following the admission of Mack-Cali as a partner, Rome sent a letter to the Issuer requesting permission from the Issuer to allow Mack-Cali to participate in Rome's due diligence with respect to the Issuer, which request was granted. The Proposal, or any amendment thereof, could result in one or more of the actions specified in clauses (a)-(j) of Item 4 of Schedule 13D, including the acquisition or disposition of additional securities of the Issuer, a merger or other extraordinary transaction involving the Issuer, a change to the present board of directors of the Issuer, a change to the present capitalization or dividend policy of the Issuer, and the delisting of the Issuer's securities from the New York Stock Exchange. The Mack-Cali Reporting Persons may, from time to time and at any time, acquire shares in the open market or otherwise and reserve the right to dispose of any or all shares hereafter acquired in the open market or otherwise, at any time and from time to time. Item 5. Interest in Securities of the Issuer Currently, the Mack-Cali Reporting Persons do not own any Shares. The Mack-Cali Reporting Persons may be deemed to be members of a "group" with Rome, the Macklowe Reporting Persons and the Icahn Reporting Persons within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Act"). As such, the group may be deemed to beneficially own (as that term is defined in Rule 13d-3 under the Act) all of the Shares beneficially owned by Rome, the Icahn Reporting Persons, the Macklowe Reporting Persons and the Mack-Cali Reporting Persons. Nothing contained herein shall be deemed to be an admission by any of the Mack-Cali Reporting Persons that they are the beneficial owners of Shares beneficially owned by any of the Icahn Reporting Persons or the Macklowe Reporting Persons, and the Mack-Cali Reporting Persons disclaim any such beneficial ownership. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer. Except as otherwise described herein or in Item 4 hereof, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the persons named in Item 2 and between such persons and any person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the securities, finder's fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
