Thornburg Mortgage Receives Majority Consent to Amend Preferred Stock Tender Offer Minimum Condition from 90% to 66 2/3% of Aggregate Liquidation Preference of Its Outstanding Preferred Stock

Thornburg Mortgage, Inc. (NYSE: TMA) announced today that a majority of the participants in the principal participation agreement component of company’s recent financing transaction approved an amendment to change the requirement that the tender offer for the preferred stock result in the tender of at least 90% of the aggregate liquidation preference of the company’s outstanding preferred stock. To successfully complete the tender offer, the company must instead complete a tender of at least 66 2/3% of the aggregate liquidation preference of each series of its outstanding preferred stock. Under the terms of the tender offer, for each share of Thornburg Mortgage Series C, D, E and F Preferred Stock that is validly tendered and accepted upon expiration of the tender offer, the holder will receive $5.00 in cash and approximately 3.5 shares of common stock. Upon the successful completion of the tender offer, the annual interest rate on the company’s Senior Subordinated Secured Notes due 2015 will be lowered from 18% to 12%, resulting in savings of approximately $69 million per year in interest payments until maturity or until the company’s Senior Subordinated Secured Notes are earlier redeemed or repurchased. Additionally, the successful completion of the tender offer will result in the termination of the Principal Participation Agreement, 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. Thornburg Mortgage is a leading single-family residential mortgage lender focused principally on prime and super-prime borrowers seeking jumbo and super-jumbo adjustable-rate mortgages.
