Thornburg Mortgage Announces Expiration of Exchange Offer and Consent Solicitation for All Series of Preferred Stock and Acceptance of Validly Tendered Shares

Thornburg Mortgage, Inc. (NYSE: TMA), announced today that the Exchange Offer and Consent Solicitation for all of the company’s outstanding shares of 8.00% Series C Cumulative Redeemable Preferred Stock (the "Series C Preferred Stock”), Series D Adjusting Rate Cumulative Redeemable Preferred Stock (the "Series D Preferred Stock”), 7.50% Series E Cumulative Convertible Redeemable Preferred Stock (the "Series E Preferred Stock”) and 10% Series F Cumulative Convertible Redeemable Preferred Stock (the "Series F Preferred Stock” and, collectively, the "Preferred Stock”) has expired and that the company has accepted valid tenders of at least 66 2/3% of each series of the Preferred Stock.

As of the expiration of the Exchange Offer and Consent Solicitation at 5:00 p.m., New York City time, on November 19, 2008, holders of Preferred Stock had tendered (i) 89.4% (5,834,744 shares) of the Series C Preferred Stock; (ii) 91.2% (3,646,556 shares) of the Series D Preferred Stock; (iii) 92.1% (2,913,110 shares) of the Series E Preferred Stock and (iv) 97.9% (29,692,293 shares) of the Series F Preferred Stock.

Shareholders who participated in the Exchange Offer and Consent Solicitation will receive 3 shares of the company’s common stock for each share of Preferred Stock validly tendered and accepted, and the company will issue a total of 126,260,109 shares of its common stock in exchange for the shares of Preferred Stock accepted in the Exchange Offer and Consent Solicitation. In addition, the company will amend its Charter to modify the terms of each series of Preferred Stock as described in the Offering Circular. Following settlement of the Exchange Offer and Consent Solicitation, approximately 690,256 shares of Series C Preferred Stock will remain outstanding, approximately 353,444 shares of Series D Preferred Stock will remain outstanding, approximately 249,390 shares of Series E Preferred Stock will remain outstanding and approximately 634,422 shares of Series F Preferred Stock will remain outstanding.

Thornburg Mortgage made this Exchange Offer and Consent Solicitation as part of the financing transaction the company entered into with various investors on March 31, 2008. By successfully completing the Exchange Offer and Consent Solicitation and upon issuance of additional warrants to the participants of the Principal Participation Agreement (the "PPA”), the annual interest rate on the company’s Senior Subordinated Secured Notes due 2015 (the "Senior Subordinated Notes”) will be lowered from 18% to 12%, resulting in savings of approximately $75.9 million per year in interest payments. Additionally, upon issuance of the additional warrants, the PPA will expire according to its terms, thereby allowing the company to retain the monthly principal payments on the mortgage backed securities collateralizing its reverse repurchase agreement borrowings once the Override Agreement terminates in March 2009, after deducting payments due under those reverse repurchase agreements.

Subsequent to the completion of the Exchange Offer and Consent Solicitation, the Preferred Stock will no longer meet the continued listing criteria under the NYSE Listing Company Manual and is expected to be delisted promptly. The Company does not intend to list the Preferred Stock on any other national securities exchange.
