This Amendment No. 1 to Schedule 13D amends and supplements the Schedule 13D, as filed with the Securities and Exchange Commission (the "SEC") on October 30, 2001 (the "Original Schedule 13D"). The Reporting Persons are: (i) GRG Investment Partnership LP, a Delaware limited partnership ("Garrabrant-CT"); and (ii) Mr. Gary R. Garrabrant ("Garrabrant"), who is the general partner of Garrabrant-CT. Garrabrant is the sole general partner of Garrabrant-CT. This statement relates to the shares of class A common stock, par value $0.01 per share ("Class A Common Stock") of Capital Trust, Inc., a Maryland corporation (the "Issuer"). The principal executive office of the Issuer is located at 410 Park Avenue, 14th Floor, New York, New York 10022. Item 5. Interest in Securities of the Issuer. ------------------------------------ Item 5 is amended as follows: (a) and (b) The aggregate percentage of shares of Class A Common Stock reported beneficially owned by the Reporting Persons as of the date of filing of this Amendment No. 1 to Schedule 13D is based upon 16,278,563 shares of Class A Common Stock issued and outstanding as of March 27, 2003 as reported in the Issuer's Annual Report on Form 10-K, as filed with the SEC on March 28, 2003. Garrabrant-CT holds of record and thereby directly beneficially owns and has the sole direct power to vote and dispose of 419,423 shares of Class A Common Stock (the "Garrabrant-CT Shares"). Garrabrant indirectly beneficially owns and has the indirect power to vote and dispose of the Garrabrant-CT Shares. Garrabrant beneficially owns and will have the sole power to vote and dispose of 32,122 shares of Class A Common A Stock issuable upon the exercise of options to purchase and the conversion of stock units to obtain shares of Class A Common Stock that are, or become within 60 days, vested and exercisable. (c) On January 29, 2003, the Issuer repurchased warrants representing 8,528,467 shares of Class A Common Stock from Travelers Insurance Company, Citigroup Alternative Investments GP, LLC and Citigroup Alternative Investments General Real Estate Mezzanine ---------------------- ------------------------- CUSIP No. 14052H100 Page 5 of 6 Pages --------- ----- ---- ---------------------- ------------------------- Investments II, LLC (collectively, the "Citigroup Affiliates") for an aggregate purchase price of $2,132,116.75. (e) As of January 29, 2003, the Citigroup Affiliates and affiliates controlling and under common control with them no longer beneficially held more than 5% of the Class A Common Stock and therefore any obligation of the Reporting Persons to report beneficial ownership of the Class A Common Stock on Schedule 13D that may have arisen from the Stockholder Approval Agreement (as defined in the Original Schedule 13D) has terminated as of such date. Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of Issuer. ---------------------------------------------------------------------- Item 6 is amended by adding the following: On March 31, 2002, June 30, 2002, September 30, 2002, December 31, 2002 and March 31, 2003, pursuant to the Issuer's incentive stock plan, Garrabrant was granted stock units which are immediately vested and convertible into 1,384, 1,520, 1,552, 1,623 and 1,412 shares of Class A Common Stock, respectively.
