      ANNALY MORTGAGE MANAGEMENT, INC. ANNOUNCES 2nd QUARTER 2003 EARNINGS

New York, New York -July 28, 2003 - Annaly Mortgage Management, Inc. (NYSE: NLY)
(the "Company") today reported earnings for the quarter ended June 30, 2003 of
$58,152,000 or $0.62 per average share outstanding, as compared to $59,369,000
or $0.72 per average share outstanding for the quarter ended June 30, 2002.

During the quarter the Company raised approximately $151.3 million in net
proceeds through a secondary offering of 9,300,700 shares of common stock.

The Company provided an annualized return on average equity of 20.79% for the
quarter ended June 30, 2003, as compared to 18.83% for the quarter ended March
31, 2003 and 23.08% for the quarter ended June 30, 2002. Dividends declared for
the quarter ended June 30, 2003 were $0.60 per share, compared to $0.60 for the
quarter ended March 31, 2003 and $0.68 per share for the quarter ended June 30,
2002. The annualized dividend yield for the quarter, based on the June 30, 2003
closing price of $19.91, was 12.05%.

"As managers, our job is to create for shareholders a steady stream of income in
the form of dividends," said Michael A.J. Farrell, Chairman, Chief Executive
Officer and President of Annaly. "That stream of income will fluctuate with the
nominal level of rates and as the yields that we earn on our assets change in
relation to our cost of funds. Investors in all markets--equities, money
markets, credit-sensitive securities--have had to adjust their return
expectations in response to the nominally low interest rate environment and the
sluggish economy, and we are no different. Our results for the quarter reflect
these market conditions, particularly the effect of high mortgage refinancing
activity. As we navigate through these markets, we believe that our portfolio of
adjustable-rate and fixed-rate mortgage-backed securities will continue to offer
competitive returns."

For the quarter ended June 30, 2003, the yield on average earning assets was
2.93% and the cost of funds on the average repurchase balance was 1.68%, which
equates to an interest rate spread of 1.25%. This is a 30 basis point decrease
over the 1.55% interest rate spread for the quarter ended March 31, 2003, when
the yield on average earning assets was 3.23% and the cost of funds on the
average repurchase balance was 1.68%, and a 120 basis point decrease over the
2.45% interest rate spread for the quarter ended June 30, 2002, when the yield
on average earning assets was 4.55% and the cost of funds on the average
repurchase balance was 2.10%.



The Constant Prepayment Rate increased to 44% during the second quarter of 2003,
as compared to 41% in the first quarter of 2003 and 25% for the quarter ended
June 30, 2002. The homeowners' prepayment option makes the average term, yield
and performance of a mortgage-backed security uncertain because of the
uncertainty in timing the return of principal. In general, prepayments decrease
the yield on a security purchased at a premium. The faster prepayments come in,
the faster that premium is amortized. The weighted average purchase price of the
portfolio was 102.5 at June 30, 2003, 102.6 at March 31, 2003, and 102.2 at June
30, 2002. "The dominant challenge today for any mortgage-backed securities
portfolio manager is maintaining performance through these periods of extremely
fast prepayments and historically low yields," said Wellington Denahan, Vice
Chairman and Chief Investment Officer. "Prepayments have reduced our spread
income through the high levels of premium amortization, and we expect to see
these effects continue near term. Nevertheless, the recent backup in 10 year
Treasury yields from 3.50% at quarter end to 4.17% on July 24, 2003 should
result in slowing refinance activity. This slowing, along with low funding
costs, should be advantageous for the Company in the long term."

For the quarter ended June 30, 2003, the Company's gain on sale of assets was
$20.2 million as compared to $11.0 million in the quarter ended March 31, 2003
and $1.3 million for the quarter ended June 30, 2002. Leverage at June 30, 2003
was 10.5:1, in comparison to 9.5:1 at March 31, 2003 and 8.8:1 at June 30, 2002.

General and administrative expenses as a percent of average assets was 0.12% for
the quarters ended June 30, 2003 and March 31, 2003 and 0.13% for the quarter
ended June 30, 2002. In addition, the Company's Dividend Efficiency Ratio,
calculated as general and administrative expenses divided by dividends paid, was
7.4%, 7.3%, and 6.3% for the quarters ended June 30, 2003, March 31, 2003, and
June 30, 2002, respectively.

At June 30, 2003, March 31, 2003, and June 30, 2002, the Company had a book
value of $12.35, $12.72, and $12.65, respectively. The Company classifies all
investment securities as "available for sale;" therefore requiring the Company
to record the entire portfolio at market value. Fixed rate securities comprised
approximately 36% of the Company's portfolio at June 30, 2003. The balance of
the portfolio was comprised of 42% adjustable rate securities and 22% LIBOR
floating rate securities. The Company has continued to avoid the introduction of
credit risk into its portfolio. As of June 30, 2003, all of the assets in the
Company's portfolio were Federal National Mortgage Association, Government
National Mortgage Association, Federal Home Loan Mortgage Corporation
mortgage-backed securities, and agency debentures, which carry an actual or
implied "AAA" rating.

The Company is a Maryland corporation which owns and manages a portfolio of
mortgage-backed securities. The Company's principal business objective is to
generate net income for distribution to stockholders from the spread between the
interest income on its mortgage-backed securities and the cost of borrowing to
finance their acquisition. The Company has elected to be taxed as a real estate
investment trust ("REIT") and currently has 94,032,753 shares of common stock
outstanding.
