           Year.

         On September 16, 2004, Reckson Associates Realty Corp. (the
"Company") filed with the office of the Department of Assessments and Taxation
of the State of Maryland Articles of Amendment to the Company's Articles of
Amendment and Restatement to change the designation of the Company's "Class A
Common Stock" to "Common Stock." The foregoing amendments were approved by a
majority of the entire Board of Directors of the Company and are limited to
changes expressly permitted by Section 2-605(a)(2) of the Maryland General
Corporation Law to be made without action by the stockholders. The Articles of
Amendment are effective as of September 16, 2004.

Item 8.01.  Other Events.

         On September 14, 2004, the Company entered into an underwriting

incorporated by reference into the Terms Agreement, dated September 14, 2004
(collectively, the "Underwriting Agreement"), between the Company and the
Underwriter, in connection with the public offering of five million shares of
the Company's common stock. The Underwriter is offering the shares to the
public at $27.50 per share, and expects to deliver the shares to purchasers on

$136.8 million after deducting the underwriting discount and other expenses.
