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) Callahan-CT General Partnership, an Illinois general partnership ("Callahan-CT"); (ii) Mr. Timothy H. Callahan ("Callahan"), who is a general partner of Callahan-CT; and (iii) Ms. Meg Siegler Callahan ("Siegler Callahan"), who is a general partner of Callahan-CT. Callahan and Siegler Callahan are the sole general partners of Callahan-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. Callahan-CT holds of record and thereby directly beneficially owns and has the sole direct power to vote and dispose of 209,711 shares of Class A Common Stock (the "Callahan-CT Shares"). Callahan indirectly beneficially owns and shares the indirect power to vote and dispose of the Callahan-CT Shares. Siegler Callahan indirectly beneficially owns and shares the indirect power to vote and dispose of the Callahan-CT Shares. (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 6 of 7 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. To the best of knowledge of the Reporting Persons, except as described in this Amendment No. 1 to Schedule 13D, none of the Reporting Persons has effected any transactions in the Class A Common Stock during the period which commenced sixty days prior to the date of the filing of this Amendment No. 1 to Schedule 13D. SIGNATURE After reasonable inquiry and to the best of its knowledge and belief, each of the undersigned certifies that the information set forth in this statement is true, complete and correct.
