      This Amendment No. 7 (this "Amendment") to the Statement on
Schedule 13D dated January 21, 2000, as amended by Amendment No.
1 thereto dated February 22, 2000, Amendment No. 2 thereto dated
July 12, 2000, Amendment No. 3 thereto dated September 8, 2000,
Amendment No. 4 thereto dated October 31, 2000, Amendment No. 5
thereto dated December 28, 2000 and Amendment No. 6 thereto dated
November 29, 2001 (as so amended, the "Schedule 13D") filed by
Fortress CAP LLC, a Delaware limited liability company ("Fortress
CAP"), Fortress Registered Investment Trust, a Delaware business
trust ("Fortress Trust"), Fortress Investment Fund LLC, a
Delaware limited liability company ("Fortress Fund"), Fortress
Investment Group LLC, a Delaware limited liability company
("Fortress Group"), and Fortress Principal Investment Holdings
LLC, a Delaware limited liability company ("FPIH"), relates to
the common stock, par value $0.01 per share (the "Common Stock"),
of Capstead Mortgage Corporation, a Maryland corporation
("Capstead"). This Amendment is filed jointly by Fortress CAP,
Fortress Trust, Fortress Fund, Fortress Group and FPIH
(collectively, the "Reporting Persons"). All capitalized terms
used but not defined herein have the meanings ascribed to them in
the Schedule 13D.

Item 4.

         Item 4 of the Schedule 13D is hereby amended and
supplemented to add the following:

           On February 28, 2003, pursuant to a block trade,
      Fortress CAP sold 200,000 shares of Common Stock at $12.50
      per share, yielding aggregate net proceeds of $2,500,000. On
      March 3, 2002, pursuant to a block trade, Fortress CAP sold
      100,000 shares of Common Stock at $12.5068 per share,
      yielding aggregate net proceeds of $1,250,680. After such
      sales, Fortress CAP was the direct beneficial owner of
      3,349,359 shares of Common Stock, which represents
      approximately 24.0% of the outstanding Common Stock. The
      Reporting Persons acquired beneficial ownership of the
      Capstead securities referenced in this Schedule 13D for
      investment purposes and for purposes of influencing the
      business and affairs of Capstead. The Reporting Persons
      intend to continuously review their investment in Capstead,
      and may in the future determine to (i) dispose of all or a
      portion of the securities of Capstead owned by them, (ii)
      acquire additional securities of Capstead, through open
      market purchases, private agreements or otherwise, (iii)
      take any other available course of action, which could
      involve one or more of the types of transactions or have one
      or more of the results described in the last paragraph of
      this Item 4 or (iv) otherwise change their investment
      intent. The Reporting Persons may, from time to time, in
      light of their investment goals, make additional
      dispositions of Common Stock. Notwithstanding anything
      contained herein to the contrary, the Reporting Persons
      specifically reserve the right to change their intentions
      with respect to any or all of such matters. In reaching any
      decision as to their course of action (as well as to the
      specific elements thereof), the Reporting Persons currently
      expect that they would take into consideration a variety of
      factors, including, but not limited to,



      Capstead's financial condition, business, operations and prospects,
      other developments concerning Capstead and the mortgage business
      generally, other business opportunities available to the Reporting
      Persons, other developments with respect to the business of the
      Reporting Persons, general economic conditions and money and stock
      market conditions, including the market price of the securities of
      Capstead.

           Other than as described herein, none of the Reporting
      Persons has any present plans or proposals which relate to
      or would result in: (a) the acquisition by any person of
      additional securities of Capstead or the disposition of
      securities of Capstead; (b) an extraordinary corporate
      transaction, such as a merger, reorganization or
      liquidation, involving Capstead or any of its subsidiaries;
      (c) a sale or transfer of a material amount of assets of
      Capstead or any of its subsidiaries; (d) any change in the
      Board of Directors or management of Capstead, including any
      plans or proposals to change the number or terms of
      directors or to fill any existing vacancies on the Board of
      Directors of Capstead; (e) any material change in the
      present capitalization or dividend policy of Capstead; (f)
      any other material change in Capstead's business or
      corporate structure; (g) changes in Capstead's articles of
      incorporation, by-laws or instruments corresponding thereto
      or other actions which may impede the acquisition of control
      of Capstead by any person; (h) a class of securities of
      Capstead being delisted from a national securities exchange
      or ceasing to be authorized to be quoted in an inter-dealer
      quotation system of a registered national securities
      association; (i) a class of equity securities of Capstead
      becoming eligible for termination of registration pursuant
      to Section 12(g)(4) of the Securities Exchange Act of 1934,
      as amended; or (j) any action similar to those enumerated
      above.

Item 5.

         Item 5 of the Schedule 13D is hereby amended and
supplemented to add the following:

           As a result of  the February 28, 2003 sale of 200,000
      shares of Common Stock and the March 3, 2002 sale of 100,000
      shares of Common Stock by the Reporting Persons in privately
      negotiated block sales as described above, Fortress CAP is
      now the direct beneficial owner of 3,349,359 shares of
      Common Stock.
