FOR IMMEDIATE RELEASE

ANNALY MORTGAGE MANAGEMENT, INC. AGREES TO ACQUIRE FIDAC, GLOBAL DISTRIBUTION
PLATFORM AND DIVERSIFICATON ARE KEY ELEMENTS

New York, New York - January 2, 2004 - Annaly Mortgage Management, Inc. (NYSE:
NLY) ("Annaly" or the "Company") announced today that it has signed a definitive
merger agreement to acquire Fixed Income Discount Advisory Company ("FIDAC").
FIDAC is a registered investment advisor which, at September 30, 2003, managed,
assisted in managing or supervised approximately $13.1 billion in gross assets
for a wide array of clients on a discretionary basis. FIDAC is fee-based asset
management business with a global distribution reach. FIDAC generally receives
annual net investment advisory fees of approximately 10-15 basis points of the
gross assets it manages, assists in managing or supervises. Annaly anticipates
that the acquisition will have a positive effect on Annaly's earnings per share
under current market conditions.

Mr. Farrell, on behalf of FIDAC, approached Annaly about the possibility of
Annaly acquiring FIDAC. Annaly's board of directors formed a special committee
of independent directors to consider this matter and the special committee
retained independent counsel and Lehman Brothers Inc. to act as its financial
advisor in connection with the merger. Following negotiations between FIDAC and
the special committee, the special committee determined that Annaly should
acquire FIDAC and Annaly entered into a Merger Agreement, dated December 31,
2003, by and among, Annaly, FIDAC, FDC Merger Sub, Inc. and the FIDAC
stockholders (the "Merger Agreement").

Pursuant to the Merger Agreement, FIDAC will be merged into a newly formed
wholly owned subsidiary of Annaly. The closing of the merger is subject to a
number of conditions, including the approval of Annaly's stockholders as
described below.

Mr. Farrell, Annaly's Chairman of the Board, Chief Executive Officer and
President, Wellington J. Denahan, Annaly's Vice Chairman and Chief Investment
Officer, Kathryn F. Fagan, Annaly's



                                       1


Chief Financial Officer and Treasurer, Jennifer S. Karve, Annaly's Executive
Vice President and Secretary, and other of the Annaly's officers and employees
are shareholders of FIDAC. Mr. Farrell, Ms. Denahan and other officers and
employees are actively involved in managing mortgage-backed securities and other
fixed income assets on behalf of FIDAC.

Under the Merger Agreement with FIDAC, the purchase price will be payable in
shares of Annaly's common stock. Upon the consummation of the merger, Annaly
will issue shares of its common stock worth $40.5 million, based upon a
valuation of shares of its common stock as of December 31, 2003, to the
stockholders of FIDAC. The Merger Agreement includes an earn out feature, under
which Annaly will pay up to an additional $49.5 million, which will be payable
in shares of its common stock, to the stockholders of FIDAC if FIDAC meets
certain revenue and pre-tax profit margin targets over the next three years as
described in the merger agreement.

The shares of Annaly's common stock issued upon consummation of the merger with
FIDAC will be registered under federal securities laws. The shares issued to the
stockholders of FIDAC upon consummation of the merger will be subject to
restrictions on resale for three years after completion of the merger, subject
to certain exceptions. The shares issued to the stockholders of FIDAC under the
earn out feature will be subject to restrictions on resale for either two years
or one year after the applicable earn out period, subject to certain exceptions.

The merger is subject to the approval of Annaly's stockholders and several other
conditions. A vote on the proposed merger will be held at the next meeting of
Annaly's stockholders. Approval of the Merger Agreement and the merger will
require the affirmative vote of the holders of a majority of Annaly's shares of
common stock voting at the stockholder meeting as long as the total vote cast at
the stockholder meeting represents a majority of the shares entitled to vote at
the stockholder meeting. Pursuant to the Merger Agreement, the FIDAC
stockholders have agreed to vote any shares of Annaly's common stock owned of
record by them in accordance with, and in the same proportion as, the votes cast
by Annaly's stockholders who are not FIDAC stockholders in connection with the
merger. Annaly is not certain that its stockholders will approve the merger or
that the other conditions to the merger will be satisfied. If the merger is not
completed, Annaly expects to continue to operate under a similar cost-sharing
arrangement to what it currently has with FIDAC.
