Item 1.01. Entry into a Material Definitive Agreement
           ------------------------------------------

        Public Offering of Common Stock
        -------------------------------

        On April 6, 2006, Annaly Mortgage Management, Inc. (the "Company")
entered into an underwriting agreement with Merrill Lynch, Pierce, Fenner &
Smith Incorporated, Citigroup Global Markets Inc., and UBS Securities LLC as
representatives of the several underwriters (collectively, the "Common Stock
Underwriters"), relating to the sale of 34,100,000 shares of Common Stock, par
value $0.01 per share (the "Common Stock"), and the granting of an
over-allotment option for an additional 5,115,000 shares of Common Stock to the
Common Stock Underwriters solely to fulfill over-allotments. The Common Stock
offering is expected to close on April 12, 2006.

         The aggregate net proceeds of the Common Stock offering, excluding the
proceeds the Company may obtain from the exercise of the over-allotment option,
to the Company (after deducting estimated expenses) are estimated to be
approximately $380.39 million.

        Public Offering of Preferred Stock
        ----------------------------------

        On April 6, 2006, the Company entered into an underwriting agreement
with Merrill Lynch, Pierce, Fenner & Smith Incorporated and Bear, Stearns & Co.
Inc. (collectively, the "Preferred Stock Underwriters"), relating to the sale of
4,000,000 shares of 6% Series B Cumulative Convertible Preferred Stock, $25.00
liquidation preference (the "Series B Preferred Stock"), and the granting of an
over-allotment option for an additional 600,000 shares of Series B Preferred
Stock to the Preferred Stock Underwriters solely to fulfill over-allotments. The
Series B Preferred Stock offering is expected to close on April 12, 2006.

         The aggregate net proceeds of the Series B Preferred Stock offering,
excluding the proceeds the Company may obtain from the exercise of the
over-allotment option, to the Company (after deducting estimated expenses) are
estimated to be approximately $96.75 million.

Item 3.03. Material Modification to Rights of Security Holders
           ---------------------------------------------------

        On April 6, 2006, the Company entered into an underwriting agreement
with the Preferred Stock Underwriters, relating to the sale of 4,000,000 shares
of Series B Preferred Stock, and the granting of an over-allotment option for an
additional 600,000 shares of Series B Preferred Stock to the Preferred Stock
Underwriters solely to fulfill over-allotments. As set forth in the Articles
Supplementary establishing the rights and preferences of the Series B Preferred
Stock filed with the Maryland State Department of Assessments and Taxation on
April 10, 2006, the Company will pay cumulative dividends on the Series B
Preferred Stock from and including the date of original issuance in the amount
of $1.50 per share each year, which is equivalent to 6% of the $25.00
liquidation preference per share. Dividends on the Series B Preferred Stock will
be payable quarterly in arrears, beginning on June 30, 2006. The Company's only
other preferred stock outstanding as of the date of this prospectus supplement
are 7,412,500 shares of its 7.875% Series A Cumulative Redeemable Preferred
Stock ("Series A Preferred Stock") with a






liquidation preference of $25.00 per share. The Series A Preferred Stock ranks
on parity with the Series B Preferred Stock.

         Holders may convert the Series B Preferred Stock into shares of the
Company's common stock subject to certain conditions. The conversion rate will
initially be 1.7730 shares of common stock per Series B Preferred Stock, which
is equivalent to an initial conversion price of approximately $14.10 per share
of common stock. The conversion rate will be subject to adjustment upon the
occurrence of specified events.

         If certain fundamental changes occur, holders may require the Company
in certain circumstances to repurchase all or part of their Series B Preferred
Stock. In addition, if a holder elects to convert the Series B Preferred Stock
in connection with a fundamental change, the Company will pay a make whole
premium by increasing the conversion rate applicable to the conversion.

         On or after April 5, 2011, the Company may, at its option, cause the
Series B Preferred Stock to be automatically converted into that number of
shares of common stock that are issuable at the then prevailing conversion rate.
The Company may exercise its conversion right only if, for 20 trading days
within any period of 30 consecutive trading days (including the last trading day
of such period), the closing price of its common stock equals or exceeds 130% of
then prevailing conversion price of the Series B Preferred Stock. Investors in
the Company's Series B Preferred Stock will generally have no voting rights, but
will have limited voting rights if the Company fails to pay dividends for six or
more quarters and under certain other circumstances.

         The Company Series B Preferred Stock is subject to certain restrictions
on ownership designed to preserve the Company's qualification as a real estate
investment trust for federal income tax purposes.

         The foregoing description of the Articles Supplementary does not
purport to be complete and is qualified in its entirety by reference to the
Articles Supplementary, which is filed as Exhibit 3.1 hereto, and is
incorporated into this report by reference.
