     NEW YORK--(BUSINESS WIRE)--Dec. 19, 2005--The Board of Directors of Annaly
Mortgage Management, Inc. (NYSE: NLY) declared the fourth quarter 2005 common
stock cash dividend of $0.10 per common share. This dividend is payable January

date is December 28, 2005.
     "As we have been discussing for several quarters," said Michael A.J.
Farrell, Chairman, Chief Executive Officer and President of Annaly, "short
duration assets have suffered most during this extended period of removing
monetary policy accommodation through the increase in the Federal Funds rate. As
a result, we are continuing to take steps to rebalance and strengthen our
portfolio. We believe that these actions will improve our financial performance
going forward." Dividends may be reinvested through Annaly's Dividend
Reinvestment Plan. Plan information may be obtained from the Plan Administrator,
ChaseMellon Shareholder Services at 1-800-842-7629, at www.annaly.com, or by
