Annaly Mortgage Management, Inc. Announces 2nd Quarter Dividend of $0.13 per Share vs. $0.11 per Share in 1st Quarter 2006; 2nd Straight Increase in Quarterly Dividend.

NEW YORK -- The Board of Directors of Annaly Mortgage Management, Inc. (NYSE: NLY) declared the second quarter 2006 common stock cash dividend of $0.13 per common share. This dividend is payable July 27, 2006 to common shareholders of record on June 30, 2006. The ex-dividend date is June 28, 2006.

Michael A.J. Farrell, Chairman, CEO and President of Annaly, commented on the dividend: "Our ability to increase our dividend this quarter even as the Federal Reserve continues its tightening campaign reflects the positive effects of our recent portfolio activity. In particular, the successful deployment of the capital raised in April, as well as the portfolio repositioning of the prior two quarters, has enabled us to increase our dividend by 18% over the prior quarter. Returns on newly-invested capital continue to be accretive to earnings and we believe the portfolio, which continues to avoid credit risk, is well-positioned to perform going forward."

The Company distributes dividends based on its current estimate of taxable earnings per common share, not GAAP earnings. Taxable and GAAP earnings will differ because of non-taxable unrealized and realized losses, differences in premium amortization, and non-deductible general and administrative expenses.

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 contacting the Company.
