          This Amendment No. 1 (this “Amendment”) amends the Schedule 13D filed with the Commission on January 24, 2008 (the “Schedule 13D”) with respect to shares of the 10% Series F Cumulative Convertible Redeemable Preferred Stock, par value $0.01 per share (the “Series F Preferred”) of Thornburg Mortgage, Inc., a Maryland corporation (the “Issuer”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Schedule 13D. This Amendment amends and restates Item 5 in its entirety as set forth below. This is the final amendment to the Schedule 13D and an exit filing for the Reporting Person with respect to the Series F Preferred.

Item 5. Interest in Securities of the Issuer

     (a) As of the date hereof, the Reporting Person no longer beneficially owns any shares of the Series F Preferred.

     (b) As of the date hereof, the Reporting Person no longer has the sole or shared power, directly or indirectly, to vote or to direct the vote or to dispose or to direct the disposition of any shares of the Series F Preferred.

     (c) Upon the successful completion of the consent solicitation by the Issuer pursuant to which amendments to the terms of the Issuer’s Series C through F Preferred Stock were adopted, the rights, preferences and privileges of the Series F Preferred became substantially similar to the other series of preferred stock of the Issuer. As a result, the Series F Preferred effectively ceased to be a separate class of equity securities for purposes of Section 16 of the Securities Exchange Act of 1934, as amended. Prior to the completion of the Exchange Offering (defined below), the Reporting Person did not beneficially own more than 10% of the Company’s preferred stock taken together as a class.

          Pursuant to an exchange offer made by the Issuer, as more fully described in the Issuer’s definitive proxy statement filed with the Commission on July 23, 2008, as amended (the “Exchange Offering”), the Issuer offered the Reporting Person 3 shares of the Issuer’s Common Stock for each share of the Series F Preferred tendered by the Reporting Person. The Reporting Person tendered of all 3,945,000 shares of the Series F Preferred held by the Reporting Person in exchange for 11,835,000 shares of the Issuer’s Common Stock from the Issuer.

     (d) None.

     (e) The Reporting Person ceased to be the beneficial owner of more than five percent of the Series F Preferred upon the successful completion of the consent solicitation and the Issuer’s acceptance of shares tendered in the Exchange Offering which expired on
November 19, 2008.
