Explanatory Note

This Post-Effective Amendment No. 1 to Form S-4 on Form S-3 contains an updated prospectus relating to shares of common stock issuable upon the exercise of certain warrants previously issued to investors in connection with the initial public offering of Enterprise Acquisition Corp., which merged with ARMOUR Residential REIT, Inc. and became a wholly owned subsidiary of ARMOUR on November 6, 2009. The updated prospectus also relates to the resale of up to 7,500,000 warrants by the selling securityholders named herein or up to 7,500,000 shares of common stock that may be issued upon exercise of the warrants by the selling securityholders. The warrants and the shares of common stock issuable upon the exercise thereof (together with certain other securities of the registrant) were initially registered by the registrant on the registration statement on Form S-4 (No. 333-160870) declared effective on October 13, 2009. This Post-Effective Amendment No. 1 is being filed in compliance with Section 10(a)(3) of the Securities Act of 1933, as amended. The prospectus included in this Post-Effective Amendment No. 1 supersedes and replaces in its entirety the proxy statement/prospectus dated October 14, 2009 that was filed with the registration statement on Form S-4. All filing fees payable in connection with the registration of the foregoing securities were previously paid in connection with the filing of the registration statement on Form S-4.

The information in this prospectus is not complete and may be changed. We may not sell these securities until the registration statement filed with the Securities and Exchange Commission is declared effective. This prospectus is a post-effective amendment to a proxy statement/prospectus dated October 14, 2009 and is not an offer to sell these securities and it is not soliciting an offer to buy these securities in any jurisdiction where the offer or sale is not permitted.

Except where the context suggests otherwise, references to “we,” “us,” “ARMOUR” or the “Company” are to ARMOUR Residential REIT, Inc.

Overview

ARMOUR Residential REIT, Inc. is a Maryland corporation that has elected to be a real estate investment trust, or REIT, for U.S. federal income tax purposes, commencing with our fiscal year ended December 31, 2009. We are externally managed by ARMOUR Residential Management LLC, or ARRM, an entity affiliated with our executive officers. We invest primarily in hybrid adjustable rate, adjustable rate and fixed rate residential mortgage-backed securities, or RMBS, issued or guaranteed by U.S. Government-chartered entities, which we refer to as Agency Securities. The entities issuing or guaranteeing the Agency Securities include:

the Federal National Mortgage Association, commonly known as Fannie Mae;

the Federal Home Loan Mortgage Corporation, commonly known as Freddie Mac; and

the Government National Mortgage Administration, commonly known as Ginnie Mae.

From time to time, a portion of our portfolio may be invested in unsecured notes and bonds issued by U.S. Government-chartered entities, which we refer to as Agency Debt. Agency Debt includes:

U.S. Treasuries; and

money market instruments.

We seek attractive long-term investment returns by investing our equity capital and borrowed funds in our targeted asset class. We earn returns on the spread between the yield on our assets and our costs, including the interest cost of the funds we borrow, after giving effect to our interest rate mitigation strategies, which include investment and derivatives.

When acquiring Agency Securities, we typically finance our acquisitions with borrowings under a series of short-term repurchase agreements at the most competitive interest rates available to us and then cost-effectively mitigate our interest rate and other risks based on our entire portfolio of assets, liabilities and derivatives and our management's view of the market. Successful implementation of this approach requires us to address and effectively mitigate interest rate risk and maintain adequate liquidity.

Our Manager

We are externally managed by ARRM, a Delaware limited liability company, pursuant to a management agreement between us and ARRM. As an externally-managed company, we depend on the diligence, experience and skill of ARRM for the selection, acquisition, structuring, interest rate risk mitigation and monitoring of our Agency Securities, Agency Debt and associated borrowings. We do not have any employees whom we compensate directly with salaries or other compensation. ARRM currently has six full-time employees.

The management agreement requires ARRM to manage our business affairs in conformity with certain restrictions contained therein, including any material operating policies adopted by us. ARRM's role as manager is subject to the direction and oversight of our board of directors. ARRM is responsible for:

advising us with respect to, arranging for, and managing the acquisition, financing, management and disposition of, our investments;

evaluating the duration and prepayment risk of our investments and arranging borrowing and interest rate risk mitigation strategies; and

coordinating our capital raising activities.

In conducting these activities, ARRM also advises us on the formulation of, and implements, our operating strategies and policies, arranges for our acquisition of assets, monitors the performance of our assets, arranges for various types of financing and interest rate risk mitigation strategies, and provides administrative and managerial services in connection with our day-to-day operations, as may be required from time to time for our management and our assets (other than assets solely being managed by any other manager).

Operating and Regulatory Structure

REIT Qualification

We have elected to qualify and be taxed as a REIT under the Internal Revenue Code, or the Code. We believe that we are organized in conformity with the requirements for qualification as a REIT under the Code and that our manner of operations and corporate structure and stockholder ownership enables us to meet on a continuing basis the requirements for taxation as a REIT for federal income tax purposes. As a REIT, we are generally not subject to federal income tax on the REIT taxable income that we distribute to our stockholders currently. If we fail to qualify as a REIT in any taxable year and do not qualify for certain statutory relief provisions, we will be subject to federal income tax at regular corporate rates. Even if we qualify as a REIT for federal income tax purposes, we may still be subject to some federal, state and local taxes on our income.

1940 Act Exemption

We conduct our business so as not to become regulated as an investment company under the Investment Company Act of 1940, as amended, or the 1940 Act. If we were to fall within the definition of an investment company, we would be unable to conduct our business as described in this prospectus.

Restrictions on Ownership of our Common Stock

To assist us in complying with the REIT limitations on the concentration of ownership imposed by the Code, among other purposes, our charter prohibits, with certain exceptions, any stockholder from beneficially or constructively owning, applying certain attribution rules under the Code (including deemed ownership of shares underlying warrants or options to purchase stock), more than 9.8% by value or number of shares, whichever is more restrictive, of our outstanding shares of common stock. Our board of directors may, in its sole discretion, waive the 9.8% ownership limit in certain circumstances. Currently, there are holders of our capital stock and/or warrants whose ownership exceeds the thresholds set forth in our charter. We have granted waivers from the 9.8% charter restriction for holders where, based on representations, covenants and agreements received from such holders, we determined that such waivers would not jeopardize our status as a REIT.

Dividend Policy

In order to maintain our qualification as a REIT for U.S. federal income tax purposes, we are required to distribute at least 90% of our annual REIT taxable income, determined without regard to the deduction for dividends paid and excluding any net capital gain. Accordingly, we pay cash dividends of all or substantially all of our taxable income to holders of our common stock out of assets legally available for such purposes. We are not restricted from using the proceeds of equity or debt offerings to pay dividends, but we do not intend to do so. The timing and amount of any dividends we pay to holders of our common stock will be at the discretion of our board of directors and will depend upon various factors, including our earnings and financial condition, maintenance of REIT status, applicable provisions of the Maryland General Corporation Law, or MGCL, and such other factors as our board of directors deems relevant.

Corporate Information

We were incorporated in the state of Maryland on February 5, 2008. On November 1, 2009, we consummated a business combination with Enterprise Acquisition Corp., a publicly traded blank check company formed for the purposes of acquiring an operating business. As a result of this transaction, which we refer to as the Business Combination, we became a publicly traded company.

Our principal offices are located at 3001 Ocean Drive, Suite 201, Vero Beach, Florida 32963. Our phone number is (772) 617- 4340. Our website is www.ARMOURREIT.com. The contents of our website are not a part of this prospectus. The information on our website is not intended to form a part of or be incorporated by reference into this prospectus.


THE OFFERING

This prospectus covers (i) 32,500,000 shares of common stock that may be issued upon exercise of warrants by warrantholders and (ii) the resale by the selling securityholders of up to 7,500,000 warrants and/or up to 7,500,000 shares of common stock that may be issued upon exercise of those warrants.

Securities offered by ARMOUR:	32,500,000 shares of common stock that may be issued upon exercise of the warrants.

Securities offered by the Selling Securityholders:	Resale of 7,500,000 warrants and 7,500,000 shares of common stock that may be issued upon exercise of those warrants.

Common Stock:

Number of shares of common stock outstanding before this offering:	32,254,054

Number of shares of common stock to be outstanding after this offering:	64,754,054 (assuming all warrants are exercised). There is no assurance that the warrantholders will elect to exercise any or all of the warrants.

Warrants:
Number of warrants outstanding before this offering:	32,500,000

Number of warrants outstanding after this offering:	0 (assuming all warrants are exercised). There is no assurance that the warrantholders will elect to exercise any or all of the warrants.

Exercisability of Warrants:	Each warrant is exercisable for one share of our common stock.

	The 7,500,000 warrants registered for resale hereunder are held by certain persons who may be our affiliates or may be deemed holders of restricted securities. As of January 28, 2011, Staton Bell Blank Check LLC, an entity affiliated with our directors ("SBBC"), owns 6,940,497 of the 7,500,000 warrants and Wells Fargo and Company owns the remaining 559,503 warrants, which it acquired from SBBC in a private placement transaction in March 2010. These 7,500,000 warrants are exercisable on a cashless basis for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the Fair market Value of the common stock by (y) the Fair Market Value of the common stock, pursuant to the warrant agreement. Fair Market Value is defined as the average last sales price of the common stock for the five trading days ending on the trading day preceding the date of exercise.

Exercise Price:	$11.00, or such other lower price as we may establish pursuant to the warrant agreement, which allows us to lower the exercise price in our sold discretion.

Exercise Period:	The warrants will expire on November 7, 2013 at 5:00 p.m., New York Time, or earlier upon redemption.

Use of proceeds:	We will receive $11.00, or such lower price as we may establish pursuant to the warrant agreement, for each warrant exercised for the purchase of a share of our common stock, except for the referenced 7,500,000 warrants which may be exercised on a cashless basis. These proceeds will fund purchases of our target assets, as well as our working capital, operating expenses and other general corporate purposes. There is no assurance that the warrantholders will elect to exercise any or all of the warrants. The selling securityholders will receive all the proceeds from any resales of the 7,500,000 warrants and/or 7,500,000 shares of common stock registered for resale and covered by this prospectus. We will not receive any proceeds from resale of warrants and/or shares by the selling securityholders, but we will incur expenses in connection with the registration of the resale of such warrants and/or shares.

Transfer restrictions:	To assist us in qualifying as a REIT, ownership of shares of our common stock by any person is limited, with certain exceptions, to 9.8% by value or by number of shares, whichever is more restrictive, of our outstanding shares of common stock and 9.8% by value or by number of shares, whichever is more restrictive, of our outstanding capital stock.


Listing:	Our common stock and warrants are listed on the NYSE Amex under the symbols "ARR" and "ARR.WS," respectively.

Risk factors:	Investing in our warrants and common stock involves a high degree of risk. See "Risk Factors" beginning on page 7 of this prospectus for a discussion of some of the risks relating to investment in our warrants and common stock.

RISK FACTORS

Investing in our securities involves risks. In addition to the risk factors identified below, you should carefully consider the risks described under “Risk Factors” in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q (which descriptions are incorporated by reference herein), as well as the other information contained or incorporated by reference in this prospectus before making a decision to invest in our securities. See “Where You Can Find More Information,” below.

Risks Related to the Securities of ARMOUR

Future issuances and sales of shares of our common stock may depress the market price of our common stock or warrants or have adverse consequences for our stockholders or warrantholders.

Our charter provides that we may issue up to 250,000,000 shares of common stock. As of February 17, 2011, 32,254,054 shares of common stock were issued and outstanding and 32,500,000 warrants to purchase up to 32,500,000 shares of common stock were issued and outstanding. We cannot predict the effect, if any, of future issuances, sales, or exchanges of our common stock on the market price of our common stock or warrants. Sales or exchanges of substantial amounts of common stock or the perception that such sales or exchanges could occur may adversely affect the prevailing market price for our common stock or warrants. Also, we may issue additional shares in subsequent public offerings or private placements to acquire new assets or for other purposes. We are not required to offer any such shares to existing stockholders on a preemptive basis. Therefore, it may not be possible for existing stockholders to participate in such future share issuances, which may dilute the existing stockholders’ interests.

We have not established a minimum distribution payment level and we cannot assure you of our ability to pay distributions in the future.

We intend to continue to pay quarterly distributions and to make distributions to our stockholders in an amount such that we distribute all or substantially all of our REIT taxable income in each year, subject to certain adjustments. We have not established a minimum distribution payment level and our ability to pay distributions may be adversely affected by a number of factors, including the risk factors described herein. All distributions will be made, subject to Maryland law, at the discretion of our board of directors and will depend on our earnings, our financial condition, any debt covenants, maintenance of our REIT qualification and other factors as our board of directors may deem relevant from time to time. We cannot assure you that we will achieve results that will allow us to make a specified level of cash distributions.

Your ability to exercise your warrants may be limited by the ownership limits contained in our charter.

The ability of warrantholders to exercise their warrants may be limited by the ownership limits contained in our charter. In particular, to assist us in qualifying as a REIT, among other purposes, ownership of shares of our common stock by any person is limited under the charter, with certain exceptions, to 9.8% by value or by number of shares, whichever is more restrictive, of our outstanding shares of common stock and 9.8% by value or by number of shares, whichever is more restrictive, of our outstanding capital stock. Moreover, the terms of the warrants limit a holder’s ability to exercise warrants to ensure that such holder’s Beneficial Ownership or Constructive Ownership as defined in our charter does not exceed the restrictions contained in the charter limiting the ownership of shares of our common stock. In addition, our charter contains various other restrictions limiting the ownership and transfer of our common stock. As a result, warrantholders may not be able to exercise their warrants if such exercise would cause them to own shares of our common stock in excess of these ownership limits.

An investor will only be able to exercise a warrant if the issuance of shares of our common stock upon such exercise has been registered or qualified or is deemed exempt under the securities laws of the state of residence of the holder of the warrant.

No warrants will be exercisable by a warrantholder and we will not be obligated to issue shares of common stock unless the shares of common stock issuable upon such exercise have been registered or qualified or deemed to be exempt under the securities laws of the state of residence of the holder of the warrants. We are currently listed on the NYSE Amex, which provides an exemption from registration in every state. Accordingly, we believe holders in every state will be able to exercise their warrants as long as our prospectus relating to the shares of common stock issuable upon exercise of the warrants is current. However, there can be no assurance of this fact. If a warrantholder is unable to exercise his warrants in a particular state, he may be forced to sell his warrant and therefore lose the benefit of purchasing our stock. Furthermore, the price he receives for his warrant may not equal the difference between the exercise price and the stock price.

Our warrants may be exercised in the future, which would increase the number of shares of our common stock eligible for future resale in the public market.

Outstanding redeemable warrants to purchase an aggregate of 32,500,000 shares of our common stock (issued in connection with the conversion, pursuant to the November 2009 business combination of Enterprise Acquisition Corp. became a wholly-owned subsidiary of ARMOUR, of the Enterprise Acquisition Corp. warrants issued in Enterprise’s initial public offering (the "Enterprise IPO")) are currently exercisable at an exercise price of $11.00 per share. The warrant exercise price may be lowered under certain circumstances, including, among others, in our sole discretion at any time prior to the expiration date of the warrants for a period of not less than ten business days; provided, however, that any such reduction shall be identical in percentage terms among all of the warrants. These warrants likely will be exercised if the market price of the shares of our common stock equals or exceeds the warrant exercise price. Therefore, as long as warrants remain outstanding, there will be a drag on any increase in the price of our common stock in excess of the warrant exercise price. To the extent such warrants are exercised, additional shares of our common stock will be issued, which would dilute the ownership of existing stockholders. Further, if these warrants are exercised at any time in the future at a price lower than the book value per share of our common stock, existing stockholders could suffer substantial dilution of their investment, which dilution could increase in the event the warrant exercise price is lowered. Additionally, if we were to lower the exercise price in the near future, the likelihood of this dilution could be accelerated.

The price of our common stock could fluctuate and could cause you to lose a significant part of your investment.

The market price of our common stock may be influenced by many factors, some of which are beyond our control, including those described above and the following:

changes in financial estimates by analysts;

fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to us;

general economic conditions;

changes in market valuations of similar companies;

regulatory developments in the United States; and

additions or departures of key personnel at ARRM.

Resulting fluctuations in the price of our common stock could cause you to lose a significant part of your investment.

USE OF PROCEEDS

Unless otherwise indicated in an accompanying prospectus supplement, we intend to use all the net proceeds of the exercise of the warrants and the issuance of shares of common stock covered by this prospectus to acquire additional target assets in accordance with our objectives and strategies described in our most recent Annual Report on Form 10-K and other filings with the SEC. Our focus will be on purchasing Agency Securities and Agency Debt and other assets, subject to our investment guidelines and REIT qualification requirements. ARRM will make determinations as to the percentage of our assets that will be invested in each of our target assets. Its decisions will depend on prevailing market conditions and may change over time in response to opportunities available in different interest rate, economic and credit environments. Until appropriate assets can be identified, ARRM may invest the net proceeds from this offering in interest-bearing short- term investments, including funds that are consistent with our qualification as a REIT. These investments are expected to provide a lower net return than we will seek to achieve from our target assets. Prior to the time we have fully used the net proceeds of this offering to acquire our target assets, we may fund our quarterly cash distributions out of such net proceeds.

There is no assurance that warrantholders will exercise any or all of the warrants, or that we will receive any proceeds.

The selling securityholders will receive all the proceeds from the resale of the 7,500,000 warrants and/or 7,500,000 shares of common stock registered for resale and covered by this prospectus. We will not receive any proceeds from resale of warrants and/or shares by the selling securityholders, but we will incur expenses in connection with the registration of the resale of such warrants and/or shares.

Prior to February 2, 2010, from November 5, 2009 to February 1, 2010, our common stock and warrants were traded on the NYSE Amex. The following table sets forth the range of high and low closing prices or bid information, as applicable, for the common stock and warrants for the periods indicated since the consummation of the business combination with Enterprise on November 5, 2009. Over-the-counter market quotations reflect inter-dealer prices, without retail mark-up, mark-down or commission and may not necessarily represent actual transactions.

Holders of Common Equity

As of February 17, 2011, we had one stockholder of record of our outstanding common stock, and two holders of record of our outstanding warrants. We believe there are currently in excess of 400 beneficial owners of our common stock and warrants.

DIVIDEND POLICY

We have elected to be taxed as a REIT for U.S. federal income tax purposes commencing with our taxable year ended December 31, 2009. U.S. federal income tax law requires that a REIT distribute with respect to each year at least 90% of its REIT taxable income, determined without regard to the deduction for dividends paid and excluding any net capital gain. If our cash available for distribution is less than 90% of our REIT taxable income, we could be required to sell assets or borrow funds to pay cash dividends or we may make a portion of the required dividend in the form of a taxable stock dividend or dividend of debt securities. We will generally not be required to pay dividends with respect to activities conducted through any domestic taxable REIT subsidiary, or TRS.

In order to maintain our qualification as a REIT for U.S. federal income tax purposes, we are required to distribute at least 90% of our annual REIT taxable income, determined without regard to the deduction for dividends paid and excluding any net capital gain. Accordingly, we intend to continue to pay regular dividends of all or substantially all of our taxable income to holders of our common stock out of assets legally available for such purposes. To date, our distributions have been in the form of quarterly cash dividends. However, commencing in January 2011, we intend to pay cash dividends to our stockholders on a monthly, rather than on a quarterly, basis.

On November 5, 2009, we declared a dividend of $0.13 per share of common stock, which we paid in December 2009 and January 2010 to stockholders of record on October 5, 2009. On March 5, 2010, we declared a first quarter 2010 dividend of $0.40, which we paid on April 29, 2010 to stockholders of record on March 15, 2010. On May 25, 2010, we declared a second quarter 2010 dividend of $0.40 to stockholders of record on June 3, 2010, which we paid on July 29, 2010. On September 14, 2010, we declared a dividend of $0.36 per share of common stock to stockholders of record as of September 23, 2010, which we paid on October 29, 2010. On December 10, 2010, we declared a dividend of $0.36 per share of common stock to stockholders of record as of December 20, 2010, to be paid on December 27, 2010. We also announced that a monthly dividend rate of $0.12 will be payable for each of the three months in the first fiscal quarter of 2011 as set forth below:

Record Date	Payment Date

January 15, 2011	January 28, 2011
February 15, 2011	February 25, 2011
March 15, 2011	March 30, 2011

The timing and amount of any dividends we pay to holders of our common stock will be at the discretion of our board of directors and will depend upon various factors, including our earnings and financial condition, maintenance of REIT status, applicable provisions of the MGCL and such other factors as our board of directors deems relevant.

Except as disclosed above under the heading "Use of Proceeds," we presently have no intention of using the proceeds of this offering or any offering of our equity or debt or other financings to fund distributions to stockholders. However, there are no restrictions in our charter or in any agreement to which we are a party that prohibits us from doing so. In the event that we elect to fund any distribution to our stockholders from sources other than our earnings, the amount of capital available to us to purchase our target assets would decrease, which could have an adverse effect on our overall financial results and performance.

Our results of operations, financial condition, cash flows and liquidity will, in turn, be affected by various factors, including the net interest and other income from our portfolio, our operating expenses and any other expenditures. For more information regarding risk factors that could materially adversely affect our results of operations, financial condition, cash flows, liquidity, business and prospects, see “Risk Factors.”

We anticipate that our dividends generally will be taxable as ordinary income to our stockholders, although a portion of the dividends may be designated by us as qualified dividend income or capital gain or may constitute a return of capital. We will furnish annually to each of our stockholders a statement setting forth dividends paid during the preceding year and their characterization as ordinary income, return of capital, qualified dividend income or capital gain.

SELLING SECURITYHOLDERS

The selling securityholders or their permitted pledgees, donees, transferees or other successors in interest, collectively referred to in this prospectus as “selling securityholders,” may from time to time offer and sell any and all of the warrants and/or common stock offered under this prospectus. This prospectus covers the resale of (i) up to 7,500,000 warrants issued in connection with the merger with Enterprise, each of which entitles the registered holder to purchase one share of our common stock, and (ii) up to 7,500,000 shares of common stock that may be issued upon exercise of such warrants.

Each securityholder that sells warrants or shares of common stock pursuant to this prospectus may be deemed to be an “underwriter” within the meaning of the Securities Act of 1933, or the Securities Act. Any commissions received by a broker or dealer in connection with resales of our warrants and common stock may be deemed to be underwriting commissions or discounts under the Securities Act.

The following table names certain securityholders who may sell warrants and shares pursuant to this prospectus and presents certain information with respect to beneficial ownership of our securities. The information presented regarding the selling securityholders is based upon representations made by the selling securityholders to us. We do not know which (if any) of the securityholders named below actually will offer to sell warrants or shares pursuant to this prospectus, or the number of warrants or shares that each of them will offer.

Beneficial ownership is determined in accordance with Rule 13d-3 under the Securities Exchange Act of 1934, or the Exchange Act. A person is deemed to be the beneficial owner of any securities if that person has or shares voting power or investment power with respect to those securities, or has the right to acquire beneficial ownership at any time within 60 days of the date of the table. As used herein, “voting power” is the power to vote or direct the voting of securities and “investment power” is the power to dispose or direct the disposition of securities.

Because the selling securityholders may offer all, some or none of the warrants and shares of the common stock pursuant to this prospectus, and because there currently are no agreements, arrangements or understandings with respect to the resale of any of these warrants and shares, no definitive estimate can be given as to the amount of warrants and shares that will be held by the selling securityholders after completion of the offering to which this prospectus relates. The following table has been prepared assuming that the selling securityholders sell all of the warrants and/or shares of our common stock beneficially owned by them that have been registered by us pursuant to this prospectus and do not acquire nor dispose of any additional warrants or shares of common stock, or rights to purchase other warrants or shares of common stock, after the date on which they provided the information set forth in the table below. We cannot advise you as to whether the selling securityholders will in fact sell any or all of their warrants and shares of common stock. In addition, the selling securityholders may have sold, transferred or otherwise disposed of, or may sell, transfer or otherwise dispose of, at any time and from time to time, the warrants and shares of common stock in transactions exempt from the registration requirements of the Securities Act after the date on which they provided the information set forth in the table below.

Information concerning the selling securityholders may change from time to time, and any changed information will be set forth in prospectus supplements or post-effective amendments, as may be appropriate.

DESCRIPTION OF SECURITIES

The following is a summary of the rights and preferences of our securities. While we believe that the following description covers the material terms of our securities, the description may not contain all of the information that is important to you. We encourage you to read carefully this entire prospectus, our charter and bylaws and the other documents we refer to for a more complete understanding of our securities. Copies of our charter and bylaws are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information” and "Incorporation of Certain Documents by Reference."

General

Our charter provides that we may issue up to 250,000,000 shares of common stock, $0.001 par value per share, and 25,000,000 shares of preferred stock, $0.001 par value per share. Our charter authorizes our board of directors, with the approval of a majority of the entire board of directors, to amend our charter to increase or decrease the aggregate number of authorized shares of stock or the number of shares of stock of any class or series without stockholder approval. As of February 17, 2011, 32,254,054 shares of common stock were issued and outstanding and no shares of preferred stock were issued and outstanding. Under Maryland law, stockholders are not generally liable for our debts or obligations.

Shares of Common Stock

All of the outstanding shares of common stock have been duly authorized, validly issued, fully paid and non-assessable. Subject to the preferential rights of any other class or series of shares of stock and to the provisions of our charter regarding the restrictions on ownership and transfer of shares of stock, holders of shares of common stock are entitled to receive dividends on such shares of common stock out of assets legally available for such purposes if, as and when authorized by our board of directors and declared by us, and the holders of shares of our common stock are entitled to share ratably in our assets legally available for distribution to our stockholders in the event of our liquidation, dissolution or winding up after payment of or adequate provision for all our known debts and liabilities.

The shares of common stock do not represent any interest in or obligation of ARRM. Further, the shares are not a deposit or other obligation of any bank, are not an insurance policy of any insurance company and are not insured or guaranteed by the Federal Deposit Insurance Company, any other governmental agency or any insurance company. The shares of common stock do not benefit from any insurance guaranty association coverage or any similar protection.

Subject to the provisions of our charter regarding the restrictions on transfer of shares of stock and except as may otherwise be specified in the terms of any class or series of shares of common stock, each outstanding share of common stock entitles the holder to one vote on all matters submitted to a vote of stockholders, including the election of directors, and, except as provided with respect to any other class or series of shares of stock, the holders of such shares of common stock will possess exclusive voting power. There is no cumulative voting in the election of our board of directors, which means that the holders of a majority of the outstanding shares of common stock can elect all of the directors then standing for election, and the holders of the remaining shares will not be able to elect any directors.

Holders of shares of common stock have no preference, conversion, exchange, sinking fund, redemption or appraisal rights and have no preemptive rights to subscribe for any our securities. Subject to the provisions of our charter regarding the restrictions on ownership and transfer of shares of stock, shares of common stock have equal dividend, liquidation and other rights.

Under the Maryland General Corporation Law, or MGCL, a Maryland corporation generally cannot dissolve, amend its charter, merge with another entity, transfer all or substantially all of its assets, engage in a share exchange or engage in similar transactions outside the ordinary course of business unless approved by the affirmative vote of stockholders holding at least two-thirds of the votes entitled to be cast on the matter unless a lesser percentage (but not less than a majority of all of the votes entitled to be cast on the matter) is set forth in the corporation's charter. Our charter provides that these matters (other than certain amendments to the provisions of our charter related to the removal of directors, the restrictions on ownership and transfer of shares of our stock and the requirement of a two-thirds vote for amendment to these provisions) may be approved by a majority of all of the votes entitled to be cast on the matter.

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Continental Stock Transfer & Trust Company.

Warrants

Each warrant entitles the registered holder to purchase one share of our common stock at a price of $11.00 per share, subject to adjustment as discussed below.

However, the warrants relating to our shares of common stock will be exercisable only if a registration statement relating to the shares of common stock issuable upon exercise of the warrants is effective and current. The warrants will expire on November 7, 2013, at 5:00 p.m., New York Time, or earlier upon redemption.

At any time while the warrants are exercisable and there is an effective registration statement covering shares of common stock issuable upon exercise of our warrants available and current, we may call the outstanding warrants for redemption:

in whole and not in part;

at a price of $0.01 per warrant at any time after the warrants become exercisable;

upon not less than 30 days' prior written notice of redemption (the “redemption period”) to each warrantholder; and

if, and only if, the reported last sale price of the shares of common stock equals or exceeds $14.25, per share for any 20 trading days within a 30 trading day period ending on the third business day prior to the notice of redemption to warrantholders.

The right to exercise will be forfeited unless the warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of a warrant will have no further rights except to receive the redemption price for such holder's warrant upon surrender of such warrant. We will not redeem the warrants unless an effective registration statement covering the shares of our common stock issuable upon exercise of the warrants is effective and current throughout the redemption period.

The redemption criteria were originally established in connection with the Enterprise IPO to provide warrantholders with a premium to the initial warrant exercise price as well as a sufficient degree of liquidity to cushion the market reaction, if any, to the redemption call. If the foregoing conditions are satisfied and we issue notice of redemption of the warrants, each warrant holder shall be entitled to exercise his or her warrant prior to the scheduled redemption date. However, there can be no assurance that the price of the common stock will exceed the redemption trigger price or the warrant exercise price after the redemption notice is issued.

If we call the warrants for redemption, we will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” The public stockholders, however, may not make such an election at their own option. In such event, each holder would pay the exercise price by surrendering the warrants for that number of shares of common stock equal to the quotient obtained by dividing (x) the product of the number of shares of its common stock underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (defined below) by (y) the fair market value. The “fair market value” shall mean the average reported last sale price of the common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. This would have the effect of reducing the number of shares of our common stock received by holders of the warrants.

The warrants have been issued in registered form under a warrant agreement, as supplemented and amended, between Continental Stock Transfer & Trust Company, as warrant agent, Enterprise and ARMOUR. The warrant agreement provides that the terms of the warrants may be amended without consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of a majority of the then outstanding warrants in order to make any change that adversely affects the interests of the registered holders. You should review a copy of the original warrant agreement, which was filed as an exhibit to the Registration Statement on Form S-1 for the Enterprise IPO (SEC File No. 333-145154), and the supplement and amendment to such agreement, which was filed as an exhibit to the definitive proxy statement relating to the Business Combination, for a complete description of the terms and conditions applicable to the warrants.

The exercise price and number of shares of common stock issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, or recapitalization, reorganization, merger or consolidation of ARMOUR. However, the exercise price and number of shares of common stock issuable on exercise of the warrants will not be adjusted for issuances of common stock at a price below the warrant exercise price.

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price, by certified or official bank check payable to ARMOUR, for the number of warrants being exercised. Warrantholders will not have the rights or privileges of holders of common stock, including voting rights, until they exercise their warrants and receive shares of common stock. After the issuance of shares of common stock upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by stockholders.

No warrants will be exercisable and we will not be obligated to issue shares of its common stock unless at the time a holder seeks to exercise such warrant, a prospectus relating to the shares of common stock issuable upon exercise of the warrants is current and the common stock has been registered or qualified or deemed to be exempt under the securities laws of the state of residence of the holder of the warrants. Under the terms of the warrant agreement, we have agreed to use our best efforts to meet these conditions and to maintain a current prospectus relating to the shares of our common stock issuable upon exercise of the warrants until the expiration of the warrants. However, we cannot assure you that we will be able to do so and, if we do not maintain a current prospectus relating to the shares of our common stock issuable upon exercise of the warrants, holders will be unable to exercise their warrants and we will not be required to settle any such warrant exercise. If the prospectus relating to the shares of common stock issuable upon the exercise of the warrants is not current or if the common stock is not qualified or exempt from qualification in the jurisdictions in which the holders of the warrants reside, we will not be required to net cash settle or cash settle the warrant exercise, the warrants may have no value, the market for the warrants may be limited and the warrants may expire worthless.

No fractional shares will be issued upon exercise of the warrants. If a holder exercises warrants and would be entitled to receive a fractional interest of a share, we, upon exercise, will round up or down the number of shares of common stock to be issued to the warrant holder to the nearest whole number of shares of common stock.

Further, our warrant agreement, as amended, prohibits the holder of warrants from exercising such warrants to the extent that such exercise would result in beneficial ownership by such holder of more than 9.8% of the common stock then issued and outstanding (the “9.8% Blocker”). Although the 9.8% Blocker is intended to assist us in qualifying for REIT status by making it more likely that the 5/50 test will be met, the 9.8% Blocker, on its own, does not prevent the shares underlying our warrants from being treated as constructively owned to the holder or beneficial owner of such warrants for purposes of applying the 5/50 test.

Our charter contains certain ownership limits with respect to our shares of common stock. See “—Restrictions on Ownership and Transfer” below. The ability of warrantholders to exercise their warrants may be limited by these ownership limits.

Warrants Registered for Resale

7,500,000 of the 32,500,000 warrants were issued to SBBC prior to the Enterprise IPO and are being registered for resale hereunder. The 7,500,000 warrants are exercisable on a cashless basis and are not redeemable by us, in each case, so long as such warrants are held by the original purchaser thereof or his permitted transferees. As of February 17, 2011, SBBC owns 6,940,497 of the 7,500,000 warrants and Wells Fargo and Company owns the remaining 559,503 warrants, which it acquired from SBBC in a private placement transaction in March 2010. So long as the warrants are held by the original purchasers thereof and their permitted transferees, the warrant agreement provides that the 7,500,000 warrants may not be exercised unless we have an effective registration statement relating to the common stock issuable upon exercise of the warrants and a related current prospectus is available. The 7,500,000 warrants and the underlying shares of common stock are entitled to registration rights under a registration rights agreement. The 7,500,000 warrants are subject to a waiver from the ownership restrictions contained in our charter, and are subject to restrictions on exercise and restrictions on transferability for purposes of complying with rules relating to the concentration of stock ownership applicable to REITs, described under “Restrictions on Ownership and Transfer.”

Power to Reclassify Our Unissued Shares of Stock

Our charter authorizes our board of directors to classify and reclassify any unissued shares of common or preferred stock into other classes or series of shares of stock. Prior to issuance of shares of each class or series, our board of directors is required by Maryland law and by our charter to set, subject to our charter restrictions on transfer of shares of stock, the terms, preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms or conditions of redemption for each class or series. Therefore, among other things, our board of directors could authorize the issuance of shares of common or preferred stock with terms and conditions that could have the effect of delaying, deferring or preventing a change in control or other transaction that might involve a premium price for shares of our common stock or otherwise be in the best interest of our stockholders. No shares of preferred stock are presently outstanding, and we have no present plans to issue any shares of preferred stock.

Power to Increase or Decrease Authorized Shares of Common Stock and Issue Additional Shares of Common and Preferred Stock

We believe that the power of our board of directors to amend our charter to increase or decrease the number of authorized shares of stock, to issue additional authorized but unissued shares of common or preferred stock and to classify or reclassify unissued shares of common or preferred stock and thereafter to issue such classified or reclassified shares of stock will provide us with increased flexibility in structuring possible future financings and acquisitions and in meeting other needs that might arise. The additional classes or series, as well as the shares of common stock, will be available for issuance without further action by our stockholders, unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. Although our board of directors does not intend to do so, the board of directors could authorize us to issue a class or series that could, depending upon the terms of the particular class or series, delay, defer or prevent a change in control or other transaction that might involve a premium price for shares of our common stock or otherwise be in the best interest of our stockholders.

Restrictions on Ownership and Transfer

In order for us to qualify as a REIT under the Code, shares of our stock must be owned by 100 or more persons during at least 335 days of a taxable year of 12 months (other than the first year for which an election to be a REIT has been made) or during a proportionate part of a shorter taxable year. Also, after the first year for which an election to be a REIT has been made, not more than 50% of the value of the outstanding shares of stock may be owned, directly, indirectly, or constructively, by five or fewer individuals (as defined in the Code to include certain entities) during the last half of a taxable year (which we have referred to as the 5/50 test.

Our charter contains restrictions limiting the ownership and transfer of shares of our common stock and other outstanding shares of stock, warrants, and options. The relevant sections of our charter provide that, subject to the exceptions described below, no person or entity may own, or be deemed to own, by virtue of the applicable constructive ownership provisions of the Code, more than 9.8% by value or number of shares, whichever is more restrictive, of our outstanding shares of common stock (the common share ownership limit), or 9.8% by value or number of shares, whichever is more restrictive, of our outstanding capital stock (the aggregate share ownership limit). The common share ownership limit and the aggregate share ownership limit are collectively referred to herein as the “ownership limits.” A person or entity that becomes subject to the ownership limits by virtue of a violative transfer that results in a transfer to a trust, as set forth below, is referred to as a “purported beneficial transferee” if, had the violative transfer been effective, the person or entity would have been a record owner and beneficial owner or solely a beneficial owner of shares of our stock, or is referred to as a “purported record transferee” if, had the violative transfer been effective, the person or entity would have been solely a record owner of shares of our stock.

The constructive ownership rules under the Code are complex and may cause shares of stock owned actually or constructively by a group of related individuals and/or entities to be owned constructively by one individual or entity. They also cause shares underlying warrants or options to purchase our stock to be treated as if they were owned by the holder or beneficial owner of such warrants or options. As a result, the acquisition of less than 9.8% by value or number of shares, whichever is more restrictive, of our outstanding shares of common stock, (or the acquisition of an interest in an entity that owns, actually or constructively, shares of our stock) by an individual or entity, could, nevertheless, cause that individual or entity, or another individual or entity, to own constructively in excess of 9.8% by value or number of shares, whichever is more restrictive, of our outstanding shares of common stock, and thereby subject the shares of common stock, total shares of stock or warrants to the applicable ownership limit.

Our board of directors may, in its sole discretion, exempt a person from the above-referenced ownership limits. However, the board of directors may not exempt any person whose ownership of our outstanding stock would result in our being “closely held” within the meaning of Section 856(h) of the Code or otherwise would result in our failing to qualify as a REIT. In order to be considered by the board of directors for exemption, a person also must not own, directly or indirectly, an interest in our tenant (or a tenant of any entity which we own or control) that would cause us to own, directly or indirectly, more than a 9.9% interest in the tenant. The person seeking an exemption must represent to the satisfaction of our board of directors that such person will not violate these two restrictions. The person also must agree that any violation or attempted violation of these restrictions will result in the automatic transfer of the shares of stock causing the violation to a trust for the benefit of a charitable beneficiary. As a condition of its waiver, our board of directors may require an opinion of counsel or IRS ruling satisfactory to the board of directors with respect to our qualification as a REIT.

Currently, there are holders of our capital stock and/or warrants whose ownership exceeds the thresholds set forth in our charter. We have granted waivers from the charter requirements for such holders where, based on representations, covenants and agreements received from such holders, we determined that such waivers would not jeopardize our status as a REIT.

In connection with an exemption from the ownership limits or at any other time, our board of directors may from time to time increase or decrease the ownership limits for one or more persons and entities; provided, however, that any decrease may be made only prospectively as to existing holders; and provided further that the ownership limit may not be increased if, after giving effect to such increase, five or fewer individuals could own or constructively own in the aggregate, more than 49.9% in value of the shares then outstanding. Prior to the modification of the ownership limit, our board of directors may require such opinions of counsel, affidavits, undertakings or agreements as the board of directors may deem necessary or advisable in order to determine or ensure our qualification as a REIT. A reduced ownership limit will not apply to any person or entity whose percentage ownership in shares of our common stock or total shares of stock, as applicable, is in excess of such decreased ownership limit until such time as such person's or entity's percentage of shares of our common stock or total shares of stock, as applicable, equals or falls below the decreased ownership limit, but any further acquisition of shares of our common stock or total shares of stock, as applicable, in excess of such percentage ownership of shares of our common stock or total shares of stock will be in violation of such ownership limit. Additionally, the new ownership limit may not allow five or fewer individuals to own more than 49.9% in value of our outstanding shares of stock.

Our charter provisions further prohibit:

any person from beneficially or constructively owning, applying certain attribution rules of the Code, shares of our stock, which includes ownership of warrants, that would result in our being “closely held” under Section 856(h) of the Code or otherwise cause us to fail to qualify as a REIT; and

any person from transferring shares of our stock if such transfer would result in shares of our stock being owned by fewer than 100 persons (determined without reference to any rules of attribution).

Any person who acquires or attempts or intends to acquire beneficial or constructive ownership of shares of our stock that will or may violate any of the foregoing restrictions on transferability and ownership will be required to give written notice immediately of such event to us or, in the case of a proposed or attempted transaction, at least 15 days prior written notice to us, and provide us with such other information as we may request in order to determine the effect of such transfer on our qualification as a REIT. The foregoing provisions on transferability and ownership will not apply if our board of directors determines that it is no longer in our best interests to attempt to qualify, or to continue to qualify, as a REIT.

Pursuant to our charter, if any transfer of shares of our stock would result in shares of our stock being owned by fewer than 100 persons, such transfer will be null and void and the intended transferee will acquire no rights in such shares. In addition, if any purported transfer of shares of our stock or any other event would otherwise result in any person violating the ownership limits or such other limit established by our board of directors or in our being “closely held” under Section 856(h) of the Code or otherwise failing to qualify as a REIT, then that number of shares (rounded up to the nearest whole share) that would cause such person to violate such restrictions will be automatically transferred to, and held by, a trust for the exclusive benefit of one or more charitable organizations selected by us and the intended transferee will acquire no rights in such shares. The automatic transfer will be effective as of the close of business on the business day prior to the date of the purported transfer or other event that results in a transfer to the trust. Any dividend or other distribution paid to the purported record transferee, prior to our discovery that the shares had been automatically transferred to a trust as described above, must be repaid to the trustee upon demand for distribution to the beneficiary by the trust. If the transfer to the trust as described above is not automatically effective, for any reason, to prevent violation of the applicable ownership limit or our being “closely held” under Section 856 (h) of the Code or otherwise failing to qualify as a REIT, then our charter provides that the transfer of the shares will be null and void and the intended transferee will acquire no rights in such shares.

Shares of stock transferred to the trustee are deemed offered for sale to us, or our designee, at a price per share equal to the lesser of (1) the price paid by the purported record transferee for the shares (or, if the event that resulted in the transfer to the trust did not involve a purchase of such shares of stock at market price, the last reported sales price reported on the NYSE Amex (or other applicable exchange) on the day of the event which resulted in the transfer of such shares of stock to the trust) and (2) the market price on the date we or our designee, accept such offer. We have the right to accept such offer until the trustee has sold the shares of stock held in the trust pursuant to the clauses discussed below. Upon a sale to us, the interest of the charitable beneficiary in the shares sold terminates, the trustee must distribute the net proceeds of the sale to the purported record transferee and any dividends or other distributions held by the trustee with respect to such shares of stock will be paid to the charitable beneficiary.

If we do not buy the shares, the trustee must, within 20 days of receiving notice from us of the transfer of shares to the trust, sell the shares to a person or entity designated by the trustee who could own the shares without violating the ownership limits or such other limit as established by our board of directors. After that, the trustee must distribute to the purported record transferee an amount equal to the lesser of (1) the price paid by the purported record transferee for the shares (or, if the event which resulted in the transfer to the trust did not involve a purchase of such shares at market price, the last reported sales price reported on the NYSE Amex (or other applicable exchange) on the day of the event which resulted in the transfer of such shares of stock to the trust) and (2) the sales proceeds (net of commissions and other expenses of sale) received by the trust for the shares. Any net sales proceeds in excess of the amount payable to the purported record transferee will be immediately paid to the charitable beneficiary, together with any dividends or other distributions thereon. In addition, if prior to discovery by us that shares of stock have been transferred to a trust, such shares of stock are sold by a purported record transferee, then such shares will be deemed to have been sold on behalf of the trust and to the extent that the purported record transferee received an amount for or in respect of such shares that exceeds the amount that such purported record transferee was entitled to receive, such excess amount must be paid to the trustee upon demand. The purported beneficial transferee or purported record transferee has no rights in the shares held by the trustee.

The trustee will be designated by us and will be unaffiliated with us and with any purported record transferee or purported beneficial transferee. Prior to the sale of any shares by the trust, the trustee will receive, in trust for the beneficiary, all dividends and other distributions paid by us with respect to the shares held in trust and may also exercise all voting rights with respect to the shares held in trust. These rights will be exercised for the exclusive benefit of the charitable beneficiary. Any dividend or other distribution paid prior to our discovery that shares of stock have been transferred to the trust will be paid by the recipient to the trustee upon demand. Any dividend or other distribution authorized but unpaid will be paid when due to the trustee.

Subject to Maryland law, effective as of the date that the shares have been transferred to the trust, the trustee will have the authority, at the trustee's sole discretion:

to rescind as void any vote cast by a purported record transferee prior to our discovery that the shares have been transferred to the trust; and

to recast the vote in accordance with the desires of the trustee acting for the benefit of the beneficiary of the trust.

However, if we have already taken irreversible action, then the trustee may not rescind and recast the vote. If our board of directors determines in good faith that a proposed transfer would violate the restrictions on ownership and transfer of shares of our stock set forth in the charter, the board of directors will take such action as it deems advisable to refuse to give effect to or to prevent such transfer, including, but not limited to, causing us to redeem the shares of stock, refusing to give effect to the transfer on our books or instituting proceedings to enjoin the transfer.

Every owner of more than 5% (or such lower percentage as required by the Code or the regulations promulgated thereunder) of our stock, within 30 days after the end of each taxable year, is required to give us written notice, stating the name and address of such owner, the number of shares of our stock which he, she or it beneficially owns and a description of the manner in which the shares are held. Each such owner shall provide ARMOUR with such additional information as we may request in order to determine the effect, if any, of his, her or its beneficial ownership on our status as a REIT and to ensure compliance with the ownership limits. In addition, each stockholder shall upon demand be required to provide us with such information as we may request in good faith in order to determine our status as a REIT and to comply with the requirements of any taxing authority or governmental authority or to determine such compliance.

These ownership limits could delay, defer or prevent a transaction or a change in control that might involve a premium price for the common stock or otherwise be in the best interests of the stockholders.

CERTAIN PROVISIONS OF THE MARYLAND GENERAL

CORPORATION LAW AND OUR CHARTER AND BYLAWS

The following summary description of certain provisions of the MGCL and our charter and bylaws does not purport to be complete and is subject to and qualified in its entirety by reference to the MGCL and the actual provisions of our charter and our bylaws, copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See “Where You Can Find More Information” and "Incorporation of Certain Documents by Reference."

Our Board of Directors

Our bylaws and charter provide that the number of directors we have may be established by our board of directors but may not be less than the minimum number required by the MGCL, nor more than 15. Pursuant to our charter, our board is composed of nine directors ― four of whom are affiliated and five of whom are independent. Our bylaws currently provide that any vacancy may be filled only by a majority of the remaining directors. Any individual elected to fill such vacancy will serve until the next annual meeting of stockholders and until a successor is duly elected and qualifies.

Pursuant to our bylaws, each of our directors is elected by our common stockholders entitled to vote to serve until the next annual meeting of stockholders and until his or her successor is duly elected and qualifies. Holders of shares of common stock will have no right to cumulative voting in the election of directors. Consequently, at each annual meeting of stockholders, the holders of a majority of the shares of common stock entitled to vote will be able to elect all of our directors.

Removal of Directors

Our charter provides that a director may be removed, with or without cause, and only by the affirmative vote of the holders of shares entitled to cast at least two thirds of all the votes of common stockholders entitled to be cast generally in the election of directors. This provision, when coupled with the power of our board of directors to fill vacancies on the board of directors, precludes stockholders from (1) removing incumbent directors except upon a substantial affirmative vote and (2) filling the vacancies created by such removal with their own nominees.

Business Combinations

Under the MGCL, certain “business combinations” (including a merger, consolidation, share exchange or, in certain circumstances, an asset transfer or issuance or reclassification of equity securities) between a Maryland corporation and an interested stockholder (defined generally as any person who beneficially owns, directly or indirectly, 10% or more of the voting power of the corporation's outstanding voting stock or an affiliate or associate of the corporation who, at any time within the two-year period immediately prior to the date in question, was the beneficial owner of 10% or more of the voting power of the then-outstanding stock of the corporation) or an affiliate of such an interested stockholder are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. Thereafter, any such business combination must be recommended by the board of directors of such corporation and approved by the affirmative vote of at least (a) 80% of the votes entitled to be cast by holders of outstanding voting shares of stock of the corporation and (b) two-thirds of the votes entitled to be cast by holders of voting stock of the corporation other than shares held by the interested stockholder with whom (or with whose affiliate) the business combination is to be effected or held by an affiliate or associate of the interested stockholder, unless, among other conditions, the corporation's common stockholders receive a minimum price (as defined in the MGCL) for their shares and the consideration is received in cash or in the same form as previously paid by the interested stockholder for its shares. Our board of directors may provide that the board's approval is subject to compliance with any terms and conditions determined by the board of directors.

These provisions of the MGCL do not apply, however, to business combinations that are approved or exempted by a board of directors prior to the time that the interested stockholder becomes an interested stockholder. Pursuant to the statute, our board of directors has by resolution exempted business combinations (1) between us and any person, provided that such business combination is first approved by our board of directors (including a majority of its directors who are not affiliates or associates of such person) and (2) between us and ARRM or its affiliates. Consequently, the five-year prohibition and the supermajority vote requirements will not apply to business combinations between us and such persons. As a result, any person described above may be able to enter into business combinations with us that may not be in the best interest of our stockholders without compliance by us with the supermajority vote requirements and other provisions of the statute.

The business combination statute may discourage others from trying to acquire control of us and increase the difficulty of consummating any offer.

Control Share Acquisitions

The MGCL provides that “control shares” of a Maryland corporation acquired in a “control share acquisition” have no voting rights except to the extent approved at a special meeting of stockholders by the affirmative vote of two-thirds of the votes entitled to be cast on the matter, excluding shares of stock in a corporation in respect of which any of the following persons is entitled to exercise or direct the exercise of the voting power of such shares in the election of directors: (1) a person who makes or proposes to make a control share acquisition, (2) an officer of the corporation or (3) an employee of the corporation who is also a director of the corporation. “Control shares” are voting shares of stock which, if aggregated with all other such shares of stock previously acquired by the acquirer, or in respect of which the acquirer is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquirer to exercise voting power in electing directors within one of the following ranges of voting power: (A) one-tenth or more but less than one-third; (B) one-third or more but less than a majority; or (C) a majority or more of all voting power. Control shares do not include shares that the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval. A “control share acquisition” means the acquisition of control shares, subject to certain exceptions.

A person who has made or proposes to make a control share acquisition, upon satisfaction of certain conditions (including an undertaking to pay expenses and making an “acquiring person statement” as described in the MGCL), may compel our board of directors to call a special meeting of stockholders to be held within 50 days of demand to consider the voting rights of the shares. If no request for a meeting is made, the corporation may itself present the question at any stockholders meeting.

If voting rights are not approved at the meeting or if the acquiring person does not deliver an “acquiring person statement” as required by the statute, then, subject to certain conditions and limitations, the corporation may redeem any or all of the control shares (except those for which voting rights have previously been approved) for fair value determined, without regard to the absence of voting rights for the control shares, as of the date of the last control share acquisition by the acquirer or of any meeting of stockholders at which the voting rights of such shares are considered and not approved. If voting rights for control shares are approved at a stockholders meeting and the acquirer becomes entitled to vote a majority of the shares entitled to vote, all other stockholders may exercise appraisal rights. The fair value of the shares as determined for purposes of such appraisal rights may not be less than the highest price per share paid by the acquirer in the control share acquisition.

The control share acquisition statute does not apply to (a) shares acquired in a merger, consolidation or share exchange if the corporation is a party to the transaction or (b) acquisitions approved or exempted by the charter or bylaws of the corporation.

Our bylaws contain a provision exempting from the control share acquisition statute any and all acquisitions by any person of shares of our stock. There is no assurance that such provision will not be amended or eliminated at any time in the future.

Subtitle 8

Subtitle 8 of Title 3 of the MGCL permits a Maryland corporation with a class of equity securities registered under the Exchange Act and at least three independent directors to elect to be subject, by provision in its charter or bylaws or a resolution of its board of directors and notwithstanding any contrary provision in the charter or bylaws, to any or all of five provisions:

a classified board;

a two-thirds vote requirement for removing a director;

a requirement that the number of directors be fixed only by vote of the directors;

a requirement that a vacancy on the board of directors be filled only by the remaining directors in office and for the remainder of the full term of the class of directors in which the vacancy occurred; and

a majority requirement for the calling of a special meeting of stockholders.

Our charter provides that, pursuant to Subtitle 8, vacancies on the board of directors may be filled only by the affirmative vote of a majority of the remaining directors in office, even if the remaining directors do not constitute a quorum, and any director elected to fill a vacancy shall serve for the remainder of the full term of the directorship in which the vacancy occurred. Through provisions in our charter and bylaws unrelated to Subtitle 8, we already (1) require the affirmative vote of the holders of not less than two-thirds of all of the votes entitled to be cast on the matter for the removal of any director from the board of directors, which removal will be allowed with or without cause, (2) vest in the board of directors the exclusive power to fix the number of directorships and (3) require, unless called by the chairman of the board of directors, chief executive officer, president or the board of directors, the written request of stockholders of not less than a majority of all the votes entitled to be cast at such a meeting to call a special meeting.

Meetings of Stockholders

Pursuant to our bylaws, a meeting of our stockholders for the election of directors and the transaction of any business will be held annually on a date and at the time set by our board of directors. In addition, the chairman of the board of directors, chief executive officer, president or board of directors may call a special meeting of our stockholders. Subject to the provisions of our bylaws, a special meeting of our stockholders will also be called by the secretary upon the written request of the stockholders entitled to cast not less than a majority of all the votes entitled to be cast at the meeting.

Amendment to Our Charter and Bylaws

Except for amendments related to removal of directors, the restrictions on ownership and transfer of shares of our stock and the requirement of a two-thirds vote for amendments to these provisions (each of which require the affirmative vote of the holders of not less than two-thirds of all the votes entitled to be cast on the matter and the approval of our board of directors), our charter may be amended only with the approval of the board of directors and the affirmative vote of the holders of a majority of all of the votes entitled to be cast on the matter.

Our board of directors has the exclusive power to adopt, alter or repeal any provision of our bylaws and to make new bylaws.

Dissolution of ARMOUR

Our dissolution must be approved by a majority of the entire board of directors and the affirmative vote of the holders of not less than a majority of all of the votes entitled to be cast on the matter.

Advance Notice of Director Nominations and New Business

Our bylaws provide that, with respect to an annual meeting of stockholders, nominations of individuals for election to the board of directors and the proposal of other business to be considered by stockholders may be made only (1) pursuant to our notice of the meeting, (2) by or at the direction of our board of directors or (3) by a stockholder who was a stockholder of record both at the time of giving his notice and at the time of the meeting and who is entitled to vote at the meeting on the election of directors or on the proposal of other business, as the case maybe, and has complied with the advance notice provisions set forth in our bylaws.

With respect to special meetings of stockholders, only the business specified in our notice of meeting may be brought before the meeting. Nominations of individuals for election to our board of directors may be made only (1) by or at the direction of our board of directors or (2) provided that the board of directors has determined that directors will be elected at such meeting, by a stockholder who was a stockholder of record both at the time of giving his notice and at the time of the meeting and who is entitled to vote at the meeting and has complied with the advance notice provisions set forth in our bylaws.

Anti-takeover Effect of Certain Provisions of Maryland Law and of Our Charter and Bylaws

Our charter and bylaws and Maryland law contain provisions that may delay, defer or prevent a change in control or other transaction that might involve a premium price for shares of our common stock or otherwise be in the best interests of our stockholders, including business combination provisions, supermajority vote requirements and advance notice requirements for director nominations and stockholder proposals. Likewise, if the provision in the bylaws opting out of the control share acquisition provisions of the MGCL were rescinded or if we were to opt into the classified board or other provisions of Subtitle 8, these provisions of the MGCL could have similar anti-takeover effects.

Indemnification and Limitation of Directors' and Officers' Liability

Maryland law permits a Maryland corporation to include in its charter a provision eliminating the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from actual receipt of an improper benefit or profit in money, property or services or active and deliberate dishonesty that is established by a final judgment and is material to the cause of action. Our charter contains such a provision that eliminates such liability to the maximum extent permitted by Maryland law.

The MGCL requires us to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made or threatened to be made a party by reason of his or her service in that capacity. The MGCL permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or threatened to be made a party by reason of their service in those or other capacities unless it is established that:

the act or omission of the director or officer was material to the matter giving rise to the proceeding and (1) was committed in bad faith or (2) was the result of active and deliberate dishonesty;

the director or officer actually received an improper personal benefit in money, property or services; or

in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful.

However, under the MGCL, a Maryland corporation may not indemnify a director or officer in a suit by or in the right of the corporation in which the director or officer was adjudged liable to the corporation or in a proceeding in which the director or officer was adjudged liable on the basis that personal benefit was improperly received. A court may order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification, even though the director or officer did not meet the prescribed standard of conduct or was adjudged liable on the basis that personal benefit was improperly received. However, indemnification for an adverse judgment in a suit by us or in our right, or for a judgment of liability on the basis that personal benefit was improperly received, is limited to expenses.

In addition, the MGCL permits a corporation to advance reasonable expenses to a director or officer upon the corporation's receipt of:

a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation; and

a written undertaking by the director or officer or on the director's or officer's behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the director or officer did not meet the standard of conduct.

Our charter authorizes us to obligate ourselves and our bylaws obligate us, to the maximum extent permitted by Maryland law in effect from time to time, to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to:

any present or former director or officer of ours who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity; or

any individual who, while a director or officer of ours and at our request, serves or has served another corporation, REIT, partnership, joint venture, trust, employee benefit plan or other enterprise as a director, officer, partner or trustee of such corporation, REIT, partnership, joint venture, trust, employee benefit plan or other enterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity.

Our charter and bylaws also permit us to indemnify and advance expenses to any person who served a predecessor of ours in any of the capacities described above and to any employee or agent of ours or a predecessor of ours.

Insofar as the foregoing provisions permit indemnification of directors, officers or persons controlling us for liability arising under the Securities Act, we have been informed that, in the opinion of the SEC, this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

REIT Qualification

Our charter provides that our board of directors may revoke or otherwise terminate our REIT election, without approval of our stockholders, if it determines that it is no longer in our best interests to continue to qualify as a REIT.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the material U.S. federal income tax considerations relating to the qualification and taxation of ARMOUR as a REIT and the acquisition, holding and disposition of our common stock. For purposes of this section, references to “ARMOUR,” “our,” “us” or “we” mean only ARMOUR Residential REIT, Inc. and not any of its subsidiaries or other lower-tier entities except as otherwise indicated. This summary is based upon the Code, the regulations promulgated by the U.S. Treasury Department, or the Treasury Regulations, current administrative interpretations and practices of the IRS (including administrative interpretations and practices expressed in private letter rulings which are binding on the IRS only with respect to the particular taxpayers who requested and received those rulings) and judicial decisions, all as currently in effect and all of which are subject to differing interpretations or to change, possibly with retroactive effect. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax considerations described below. No advance ruling has been or will be sought from the IRS regarding any matter discussed in this summary. The summary is also based upon the assumption that our operation, and the operation of our subsidiaries and other lower-tier and affiliated entities will, in each case, be in accordance with such entity's applicable organizational documents. This summary does not discuss the impact that U.S. state and local taxes, U.S. estate and gift taxes and any taxes imposed by non-U.S. jurisdictions could have on the matters discussed in this summary. This summary is for general information only, and does not purport to discuss all aspects of U.S. federal income taxation that may be important to a particular stockholder in light of its investment or tax circumstances or to stockholders subject to special tax rules, such as:

U.S. expatriates;

persons who mark-to-market our common stock;

subchapter S corporations;

U.S. stockholders (as defined below) whose functional currency is not the U.S. dollar;

financial institutions;

insurance companies;

broker-dealers;

regulated investment companies (or RICs);

REITs;

trusts and estates;

holders who receive our common stock through the exercise of employee stock options or otherwise as compensation;

persons holding our common stock as part of a “straddle,” “hedge,” “conversion transaction,”

“synthetic security” or other integrated investment;

persons subject to the alternative minimum tax provisions of the Code;

persons holding their interest in us through a partnership or similar pass-through entity;

persons holding a 10% or more (by vote or value) beneficial interest in us;

tax-exempt organizations; and

non-U.S. stockholders (as defined below, and except as otherwise discussed below).

This summary assumes that holders hold our common stock and warrants as capital assets, which generally means as property held for investment.

THE U.S. FEDERAL INCOME TAX TREATMENT OF HOLDERS OF OUR COMMON STOCK DEPENDS IN SOME INSTANCES ON DETERMINATIONS OF FACT AND INTERPRETATIONS OF COMPLEX PROVISIONS OF U.S. FEDERAL INCOME TAX LAW FOR WHICH NO CLEAR PRECEDENT OR AUTHORITY MAY BE AVAILABLE. IN ADDITION, THE U.S. FEDERAL INCOME TAX TREATMENT OF HOLDING OUR COMMON STOCK TO ANY PARTICULAR STOCKHOLDER WILL DEPEND ON THE STOCKHOLDER'S PARTICULAR TAX CIRCUMSTANCES. YOU ARE URGED TO CONSULT YOUR TAX ADVISOR REGARDING THE U.S. FEDERAL, STATE, LOCAL, AND FOREIGN INCOME AND OTHER TAX CONSEQUENCES TO YOU, IN LIGHT OF YOUR PARTICULAR INVESTMENT OR TAX CIRCUMSTANCES, OF ACQUIRING, HOLDING, AND DISPOSING OF ARMOUR COMMON STOCK.

U.S. Federal Income Tax Considerations of ARMOUR as a REIT – Taxation of ARMOUR – General

We have elected to be taxed as a REIT under Sections 856 through 860 of the Code, commencing with our taxable year ended December 31, 2009. We believe that we have been organized and intend to operate in a manner that allows us to qualify for taxation as a REIT under the Code.

The law firm of Akerman Senterfitt has acted as our counsel for tax matters in connection with this registration. We have received an opinion of Akerman Senterfitt to the effect that, commencing with our taxable year ended December 31, 2009, we have been organized and operated in conformity with the requirements for qualification and taxation as a REIT under the Code, and our actual method of operation has enabled, and our proposed method of operation will continue to enable us, to meet the requirements for qualification and taxation as a REIT under the Code. It must be emphasized that the opinion of Akerman Senterfitt is based on various assumptions relating to our organization and operation, including that all factual representations and statements set forth in all relevant documents, records and instruments are true and correct and that we will at all times operate in accordance with the method of operation described in our organizational documents and this document. Additionally, the opinion of Akerman Senterfitt is conditioned upon factual representations and covenants made by our management and the management of ARRM, regarding our organization, assets, present and future conduct of our business operations and other items regarding our ability to continue to meet the various requirements for qualification as a REIT, and assumes that such representations and covenants are accurate and complete and that we will take no action that could adversely affect our qualification as a REIT. While we believe we are organized and intend to operate so that we will qualify as a REIT, given the highly complex nature of the rules governing REITs, the ongoing importance of factual determinations and the possibility of future changes in our circumstances or applicable law, no assurance can be given by Akerman Senterfitt or us that we will so qualify for any particular year. Akerman Senterfitt will have no obligation to advise us or the holders of our shares of common stock of any subsequent change in the matters stated, represented or assumed or of any subsequent change in the applicable law. You should be aware that opinions of counsel are not binding on the IRS, or any court, and no assurance can be given that the IRS will not challenge the conclusions set forth in such opinions.

Qualification and taxation as a REIT depend on our ability to meet, on a continuing basis, through actual results of operations, distribution levels, diversity of share ownership and various qualification requirements imposed upon REITs by the Code, the compliance with which will not be reviewed by Akerman Senterfitt. In addition, our ability to qualify as a REIT may depend in part upon the operating results, organizational structure and entity classification for U.S. federal income tax purposes of certain entities in which we invest. Our ability to qualify as a REIT also requires that we satisfy certain asset and income tests, some of which depend upon the fair market values of assets directly or indirectly owned by us or which serve as security for loans made by us. Such values may not be susceptible to a precise determination. Accordingly, no assurance can be given that the actual results of our operations for any taxable year will satisfy the requirements for qualification and taxation as a REIT.

Taxation of REITs in General

As indicated above, qualification and taxation as a REIT depend on our ability to meet, on a continuing basis, through actual results of operations, distribution levels, diversity of share ownership and various qualification requirements imposed upon REITs by the Code. The material qualification requirements are summarized below, under “- Requirements for Qualification as a REIT.” While we believe that we will operate so that we qualify as a REIT, no assurance can be given that the IRS will not challenge our qualification as a REIT or that we will be able to operate in accordance with the REIT requirements in the future.

Provided that we qualify as a REIT, we will generally be entitled to a deduction for dividends that we pay and, therefore, will not be subject to U.S. federal corporate income tax on our net taxable income that is currently distributed to our stockholders. This treatment substantially eliminates the “double taxation” with respect to distributed income at the corporate and stockholder levels that results generally from investment in a corporation. Rather, income generated by a REIT and distributed to stockholders generally is taxed only at the stockholder level, upon a distribution of dividends by the REIT. See “- Taxation of Taxable U.S. Stockholders.”

For tax years through 2010, stockholders who are individual U.S. stockholders (as defined below) are generally taxed on corporate dividends at a maximum rate of 15% (the same as long-term capital gains), thereby substantially reducing, though not completely eliminating, the double taxation that has historically applied to corporate dividends. With limited exceptions, however, dividends received by individual U.S. stockholders from us or from other entities that are taxed as REITs will continue to be taxed at rates applicable to ordinary income, which will be as high as 35% through 2010. Net operating losses, foreign tax credits and other tax attributes of a REIT generally do not pass through to the stockholders of the REIT, subject to special rules for certain items, such as capital gains, recognized by REITs.

Even if we qualify for taxation as a REIT, however, we will be subject to U.S. federal income taxation as follows:

We will be taxed at regular U.S. federal corporate income tax rates on any undistributed income, including undistributed net capital gains. We may be subject to the “alternative minimum tax” on our items of tax preference, if any.

If we have net income from prohibited transactions, which are, in general, sales or other dispositions of property held primarily for sale to customers in the ordinary course of business, other than foreclosure property, such income will be subject to a 100% tax.

If we elect to treat property that we acquire in connection with a foreclosure of a mortgage loan or from certain leasehold terminations as “foreclosure property,” we may thereby avoid (a) the 100% tax on gain from a resale of that property (if the sale would otherwise constitute a prohibited transaction) and (b) the inclusion of any income from such property not qualifying for purposes of the REIT gross income tests discussed below, but the income from the sale or operation of the property may be subject to corporate income tax at the highest applicable rate (currently 35%).

If we fail to satisfy the 75% gross income test or the 95% gross income test, as discussed below, but nonetheless maintain our qualification as a REIT because other requirements are met, we will be subject to a 100% tax on an amount equal to (a) the greater of (1) the amount by which we fail the 75% gross income test or (2) the amount by which we fail the 95% gross income test, as the case maybe, multiplied by (b) a fraction intended to reflect our profitability.

If we fail to satisfy any of the REIT asset tests, as described below, other than a failure of the 5% or 10% REIT asset tests that does not exceed a statutory de minimis amount as described more fully below, but our failure is due to reasonable cause and not due to willful neglect and we nonetheless maintain our REIT qualification because of specified cure provisions, we will be required to pay a tax equal to the greater of $50,000 or the highest corporate tax rate (currently 35%) of the net income generated by the nonqualifying assets during the period in which we failed to satisfy the asset tests.

If we fail to satisfy any provision of the Code that would result in our failure to qualify as a REIT (other than a gross income or asset test requirement) and the violation is due to reasonable cause and not willful neglect, we may retain our REIT qualification but we will be required to pay a penalty of $50,000 for each such failure.

If we fail to distribute during each calendar year at least the sum of (a) 85% of our REIT ordinary income for such year, (b) 95% of our REIT capital gain net income for such year and (c) any undistributed taxable income from prior periods (the foregoing sum is referred to as the required distribution), we will be subject to a 4% excise tax on the excess of the required distribution over the sum of (1) the amounts actually distributed (taking into account excess distributions from prior years), plus (2) retained amounts on which income tax is paid at the corporate level.

We may be required to pay monetary penalties to the IRS in certain circumstances, including if we fail to meet record- keeping requirements intended to monitor our compliance with rules relating to the composition of our stockholders.

A 100% excise tax may be imposed on some items of income and expense that are directly or constructively paid between us and any taxable REIT subsidiary, or TRS, we may own if and to the extent that the IRS successfully adjusts the reported amounts of these items.

If we acquire appreciated assets from a corporation that is not a REIT in a transaction in which the adjusted tax basis of the assets in our hands is determined by reference to the adjusted tax basis of the assets in the hands of the non-REIT corporation, we will be subject to tax on such appreciation at the highest corporate income tax rate then applicable if we subsequently recognize gain on a disposition of any such assets during the 10-year period following their acquisition from the non-REIT corporation. The results described in this paragraph assume that the non-REIT corporation will not elect, in lieu of this treatment, to be subject to an immediate tax when the asset is acquired by us.

We will generally be subject to tax on the portion of any excess inclusion income derived from an investment in residual interests in real estate mortgage investment conduits (or REMICs) to the extent our stock is held by specified tax-exempt organizations not subject to tax on unrelated business taxable income. Similar rules will apply if we own an equity interest in a taxable mortgage pool. To the extent that we own a REMIC residual interest or a taxable mortgage pool through a TRS, we will not be subject to this tax.

We may elect to retain and pay income tax on our net long-term capital gain. In that case, a stockholder would include its proportionate share of our undistributed long-term capital gain (to the extent we make a timely designation of such gain to the stockholder) in its income, would be deemed to have paid the tax that we paid on such gain, and would be allowed a credit for its proportionate share of the tax deemed to have been paid, and an adjustment would be made to increase the stockholder's basis in our common stock. Stockholders that are U.S. corporations will also appropriately adjust their earnings and profits for the retained capital gains in accordance with Treasury Regulations to be promulgated.

We may have subsidiaries or own interests in other lower-tier entities that are subchapter C corporations, the earnings of which would be subject to U.S. federal corporate income tax.

In addition, we may be subject to a variety of taxes other than U.S. federal income tax, including payroll taxes and state, local, and foreign income, franchise property and other taxes. We could also be subject to tax in situations and on transactions not presently contemplated.

Requirements for Qualification as a REIT

The Code defines a REIT as a corporation, trust or association:

(1) that is managed by one or more trustees or directors;

(2)

the beneficial ownership of which is evidenced by transferable shares or by transferable certificates of beneficial interest;

(3)

that would be taxable as a domestic corporation but for the special Code provisions applicable to REITs;

(4)

that is neither a financial institution nor an insurance company subject to specific provisions of the Code;

(5)

the beneficial ownership of which is held by 100 or more persons during at least 335 days of a taxable year of 12 months, or during a proportionate part of a taxable year of less than 12 months;

(6)

in which, during the last half of each taxable year, not more than 50% in value of the outstanding stock is owned, directly or indirectly, by five or fewer “individuals” (as defined in the Code to include specified entities);

(7)

which meets other tests described below, including with respect to the nature of its income and assets and the amount of its distributions; and

(8)

that makes an election to be a REIT for the current taxable year or has made such an election for a previous taxable year that has not been terminated or revoked.

The Code provides that conditions (1) through (4) must be met during the entire taxable year, and that condition (5) must be met during at least 335 days of a taxable year of 12 months, or during a proportionate part of a shorter taxable year. Conditions (5) and (6) do not need to be satisfied for the first taxable year for which an election to become a REIT has been made. Our charter provides restrictions regarding the ownership and transfer of our shares, which are intended, among other purposes to assist in satisfying the share ownership requirements described in conditions (5) and (6) above. For purposes of condition (6), an “individual” generally includes a supplemental unemployment compensation benefit plan, a private foundation or a portion of a trust permanently set aside or used exclusively for charitable purposes, but does not include a qualified pension plan or profit sharing trust.

To monitor compliance with the share ownership requirements, we are generally required to maintain records regarding the actual ownership of our shares. To do so, we must demand written statements each year from the record holders of significant percentages of our shares of stock, in which the record holders are to disclose the actual owners of the shares (i.e., the persons required to include in gross income the dividends paid by us). A list of those persons failing or refusing to comply with this demand must be maintained as part of our records. Failure by us to comply with these record-keeping requirements could subject us to monetary penalties. If we satisfy these requirements and after exercising reasonable diligence would not have known that condition (6) is not satisfied, we will be deemed to have satisfied such condition. A stockholder that fails or refuses to comply with the demand is required by Treasury Regulations to submit a statement with its tax return disclosing the actual ownership of the shares and other information.

In addition, a corporation generally may not elect to become a REIT unless its taxable year is the calendar year. We satisfy this requirement.

Effect of Subsidiary Entities

Ownership of Partnership Interests

In the case of a REIT that is a partner in a partnership, Treasury Regulations provide that the REIT is deemed to own its proportionate share of the partnership's assets and to earn its proportionate share of the partnership's gross income based on its pro rata share of capital interests in the partnership for purposes of the asset and gross income tests applicable to REITs, as described below. However, solely for purposes of the 10% value test, described below, the determination of a REIT's interest in partnership assets will be based on the REIT's proportionate interest in any securities issued by the partnership, excluding for these purposes, certain excluded securities as described in the Code. In addition, the assets and gross income of the partnership generally are deemed to retain the same character in the hands of the REIT. Thus, our proportionate share of the assets and items of income of partnerships in which we own an equity interest is treated as an asset and as an item of income for us for purposes of applying the REIT requirements described below. Consequently, to the extent that we directly or indirectly hold a preferred or other equity interest in a partnership, the partnership's assets and operations may affect our ability to qualify as a REIT, even though we may have no control or only limited influence over the partnership.

Disregarded Subsidiaries

If a REIT owns a corporate subsidiary that is a “qualified REIT subsidiary,” that subsidiary is disregarded for U.S. federal income tax purposes, and all assets, liabilities and items of income, deduction and credit of the subsidiary are treated as assets, liabilities and items of income, deduction and credit of the REIT itself, including for purposes of the gross income and asset tests applicable to REITs, as summarized below. A qualified REIT subsidiary is any corporation, other than a TRS, that is wholly-owned by a REIT, by other disregarded subsidiaries or by a combination of the two. Single member limited liability companies that are wholly-owned by a REIT are also generally disregarded as separate entities for U.S. federal income tax purposes, including for purposes of the REIT gross income and asset tests. Disregarded subsidiaries, along with partnerships in which we hold an equity interest, are sometimes referred to herein as “pass- through subsidiaries.”

In the event that a disregarded subsidiary ceases to be wholly-owned by us (for example, if any equity interest in the subsidiary is acquired by a person other than us or another disregarded subsidiary of ours), the subsidiary's separate existence would no longer be disregarded for U.S. federal income tax purposes. Instead, it would have multiple owners and would be treated as either a partnership or a taxable corporation. Such an event could, depending on the circumstances, adversely affect our ability to satisfy the various asset and gross income tests applicable to REITs, including the requirement that REITs generally may not own, directly or indirectly, more than 10% of the value or voting power of the outstanding securities of another corporation.

Taxable REIT Subsidiaries

A REIT, in general, may jointly elect with a subsidiary corporation, whether or not wholly-owned, to treat the subsidiary corporation as a TRS. The separate existence of a TRS or other taxable corporation, unlike a disregarded subsidiary as discussed above, is not ignored for U.S. federal income tax purposes. Accordingly, such an entity would generally be subject to corporate income tax on its earnings, which may reduce the cash flow generated by us and our subsidiaries in the aggregate and our ability to make distributions to our stockholders.

We have elected for Enterprise to be treated as a TRS. This will allow Enterprise to invest in assets and engage in activities that could not be held or conducted directly by us without jeopardizing our qualification as a REIT.

A REIT is not treated as holding the assets of a TRS or other taxable subsidiary corporation or as receiving any income that the subsidiary earns. Rather, the stock issued by the subsidiary is an asset in the hands of the REIT, and the REIT generally recognizes as income the dividends, if any, that it receives from the subsidiary. This treatment can affect the gross income and asset test calculations that apply to the REIT, as described below. Because a parent REIT does not include the assets and income of such subsidiary corporations in determining the parent's compliance with the REIT requirements, such entities may be used by the parent REIT to undertake indirectly activities that the REIT rules might otherwise preclude it from doing directly or through pass-through subsidiaries or render commercially unfeasible (for example, activities that give rise to certain categories of income such as non-qualifying hedging income or inventory sales). If dividends are paid to us by one or more TRSs we may own, then a portion of the dividends that we distribute to stockholders who are taxed at individual rates generally will be eligible for taxation at preferential qualified dividend income tax rates rather than at ordinary income rates.

Certain restrictions imposed on TRSs are intended to ensure that such entities will be subject to appropriate levels of U.S. federal income taxation. First, a TRS may not deduct interest payments made in any year to an affiliated REIT to the extent that such payments exceed, generally, 50% of the TRS's adjusted taxable income for that year (although the TRS may carry forward to, and deduct in, a succeeding year the disallowed interest amount if the 50% test is satisfied in that year). In addition, if amounts are paid to a REIT or deducted by a TRS due to transactions between a REIT, its tenants and/or the TRS, that exceed the amount that would be paid to or deducted by a party in an arm's-length transaction, the REIT generally will be subject to an excise tax equal to 100% of such excess.

Gross Income Tests

In order to maintain our qualification as a REIT, we must annually satisfy two gross income tests. First, at least 75% of our gross income for each taxable year, excluding gross income from sales of inventory or dealer property in “prohibited transactions” and certain derivative instrument and foreign currency transactions, must be derived from investments relating to real property or mortgages on real property, including “rents from real property,” dividends received from and gains from the disposition of shares of other REITs, interest income derived from mortgage loans secured by real property (including certain types of mortgage-backed securities), and gains from the sale of real estate assets, as well as income from certain kinds of temporary investments. Second, at least 95% of our gross income in each taxable year, excluding gross income from prohibited transactions and certain derivative instrument and foreign currency transactions, must be derived from some combination of income that qualifies under the 75% income test described above, as well as other dividends, interest, and gain from the sale or disposition of stock or securities, which need not have any relation to real property.

For purposes of the 75% and 95% gross income tests, a REIT is deemed to have earned a proportionate share of the income earned by any partnership, or any limited liability company treated as a partnership for U.S. federal income tax purposes, in which it owns an interest, which share is determined by reference to its capital interest in such entity, and is deemed to have earned the income earned by any qualified REIT subsidiary.

Interest Income

Interest income constitutes qualifying mortgage interest for purposes of the 75% gross income test to the extent that the obligation is secured by a mortgage on real property. If we receive interest income with respect to a mortgage loan that is secured by both real property and other property and the highest principal amount of the loan outstanding during a taxable year exceeds the fair market value of the real property on the date that we acquired the mortgage loan, the interest income will be apportioned between the real property and the other property, and our income from the arrangement will qualify for purposes of the 75% gross income test only to the extent that the interest is allocable to the real property. Even if a loan is not secured by real property or is undersecured, the income that it generates may nonetheless qualify for purposes of the 95% gross income test. If we acquire or originate a construction loan, for purposes of the foregoing apportionment, the fair market value of the real property includes the fair market value of the land plus the reasonably estimated cost of improvement or developments (other than personal property) which secure the construction loan.

To the extent that the terms of a loan provide for contingent interest that is based on the cash proceeds realized upon the sale of the property securing the loan (or a shared appreciation provision), income attributable to the participation feature will be treated as gain from sale of the underlying property, which generally will be qualifying income for purposes of both the 75% and 95% gross income tests, provided that the property is not inventory or dealer property in the hands of the borrower or us.

To the extent that we derive interest income from a loan where all or a portion of the amount of interest payable is contingent, such income generally will qualify for purposes of the gross income tests only if it is based upon the gross receipts or sales and not the net income or profits of any person. This limitation does not apply, however, to a mortgage loan where the borrower derives substantially all of its income from the property from the leasing of substantially all of its interest in the property to tenants, to the extent that the rental income derived by the borrower would qualify as rents from real property had it been earned directly by us.

Any amount includible in our gross income with respect to a regular or residual interest in a REMIC generally is treated as interest on an obligation secured by a mortgage on real property. If, however, less than 95% of the assets of a REMIC consists of real estate assets (determined as if we held such assets), we will be treated as receiving directly our proportionate share of the income of the REMIC for purposes of determining the amount which is treated as interest on an obligation secured by a mortgage on real property. In addition, some REMIC securitizations include embedded interest rate swap or cap contracts or other derivative instruments that potentially could produce nonqualifying income to us.

We believe that the interest, original issue discount, and market discount income that we receive from our mortgage-related securities generally will be qualifying income for purposes of both the 75% and 95% gross income tests. However, to the extent that we own non-REMIC collateralized mortgage obligations or other debt instruments secured by mortgage loans (rather than by real property) or secured by non-real estate assets, or debt securities that are not secured by mortgages on real property or interests in real property, the interest income received with respect to such securities generally will be qualifying income for purposes of the 95% gross income test, but not the 75% gross income test. In addition, the loan amount of a mortgage loan that we own may exceed the value of the real property securing the loan. In that case, income from the loan will be qualifying income for purposes of the 95% gross income test, but the interest attributable to the amount of the loan that exceeds the value of the real property securing the loan will not be qualifying income for purposes of the 75% gross income test.

We may purchase Agency RMBS through “to-be-announced” forward contracts, or TBAs, and may recognize income or gains from the disposition of those TBAs through dollar roll transactions. There is no direct authority with respect to the qualifications of income or gains from dispositions of TBAs as gains from the sale of real property (including interests in real property and interests in mortgages on real property) or other qualifying income for purposes of the 75% gross income test. We will not treat these items as qualifying for purposes of the 75% gross income test unless we receive advice of counsel that such income and gains should be treated as qualifying for purposes of the 75% gross income test. As a result, our ability to enter into TBAs could be limited. Moreover, even if we were to receive advice of counsel as described in the preceding sentence, it is possible that the IRS could assert that such income is not qualifying income under the 75% gross income test. In the event that such income was determined not to be qualifying income for the 75% gross income test, we could be subject to a penalty tax or could fail to qualify as a REIT if such income, when added to any other non-qualifying income, exceeded 25% of our gross income.

Dividend Income

We may receive distributions from TRSs or other corporations that are not REITs or qualified REIT subsidiaries. These distributions are generally classified as dividend income to the extent of the earnings and profits of the distributing corporation. Such distributions generally constitute qualifying income for purposes of the 95% gross income test, but not the 75% gross income test. Any dividends received by us from a REIT will be qualifying income in our hands for purposes of both the 95% and 75% gross income tests.

Derivative Instrument Transactions

We may enter into derivative instrument transactions with respect to one or more of our assets or liabilities. Derivative instrument transactions could take a variety of forms, including interest rate swap agreements, interest rate cap agreements, options, futures contracts, forward rate agreements or similar financial instruments. Except to the extent provided by Treasury Regulations, any income from a derivative instrument transaction we enter into (1) in the normal course of our business primarily to manage risk of interest rate or price changes or currency fluctuations with respect to borrowings made or to be made, or ordinary obligations incurred or to be incurred, to acquire or carry real estate assets, which is clearly identified as specified in Treasury Regulations before the close of the day on which it was acquired, originated, or entered into, including gain from the sale or disposition of such a transaction, or (2) primarily to manage risk of currency fluctuations with respect to any item of income or gain that would be qualifying income under the 75% or 95% income tests which is clearly identified as such before the close of the day on which it was acquired, originated, or entered into, will not constitute gross income for purposes of the 75% or 95% gross income test. To the extent that we enter into other types of derivative instrument transactions, the income from those transactions is likely to be treated as non-qualifying income for purposes of both of the 75% and 95% gross income tests. We intend to structure any derivative instrument transactions in a manner that does not jeopardize our qualification as a REIT.

Failure to Satisfy the Gross Income Tests

We intend to monitor our sources of income, including any non-qualifying income received by us, so as to ensure our compliance with the gross income tests. If we fail to satisfy one or both of the 75% or 95% gross income tests for any taxable year, we may still qualify as a REIT for the year if we are entitled to relief under applicable provisions of the Code. These relief provisions will generally be available if our failure to meet these tests was due to reasonable cause and not due to willful neglect and, following the identification of such failure, we set forth a description of each item of our gross income that satisfies the gross income tests in a schedule for the taxable year filed in accordance with the Treasury Regulations. It is not possible to state whether we would be entitled to the benefit of these relief provisions in all circumstances. If these relief provisions are inapplicable to a particular set of circumstances involving us, we will not qualify as a REIT. As discussed above under “- Taxation of REITs in General,” even where these relief provisions apply, a tax would be imposed upon the profit attributable to the amount by which we fail to satisfy the particular gross income test.

Phantom Income

Due to the nature of the assets in which we will invest, we may be required to recognize taxable income from certain of our assets in advance of our receipt of cash flow on or proceeds from disposition of such assets, and we may be required to report taxable income in early periods that exceeds the economic income ultimately realized on such assets.

We may acquire mortgage-backed securities in the secondary market for less than their face amount. For example, it is likely that we will invest in assets, including mortgage-backed securities, requiring us to accrue original issue discount, or OID, or recognize market discount income, that generate taxable income in excess of economic income or in advance of the corresponding cash flow from the assets referred to as “phantom income.” We may also be required under the terms of the indebtedness that we incur to use cash received from interest payments to make principal payment on that indebtedness, with the effect that we will recognize income but will not have a corresponding amount of cash available for distribution to our stockholders.

Due to each of these potential differences between income recognition or expense deduction and related cash receipts or disbursements, there is a significant risk that we may have substantial taxable income in excess of cash available for distribution. In that event, we may need to borrow funds or take other actions to satisfy the REIT distribution requirements for the taxable year in which this “phantom income” is recognized.

Asset Tests

We, at the close of each calendar quarter, must also satisfy four tests relating to the nature of our assets. First, at least 75% of the value of our total assets must be represented by some combination of “real estate assets,” cash, cash items, U.S. government securities and, under some circumstances, stock or debt instruments purchased with new capital. For this purpose, real estate assets include interests in real property, such as land, buildings, leasehold interests in real property, stock of other corporations that qualify as REITs and certain kinds of mortgage-backed securities and mortgage loans. A regular or residual interest in a REMIC is generally treated as a real estate asset. If, however, less than 95% of the assets of a REMIC consists of real estate assets (determined as if we held such assets), we will be treated as owning our proportionate share of the assets of the REMIC. Assets that do not qualify for purposes of the 75% test are subject to the additional asset tests described below. Second, the value of any one issuer's securities owned by us may not exceed 5% of the value of its gross assets. Third, we may not own more than 10% of any one issuer's outstanding securities, as measured by either voting power or value. Fourth, the aggregate value of all securities of TRSs held by us may not exceed 25% of the value of our gross assets.

The 5% and 10% asset tests do not apply to securities of TRSs and qualified REIT subsidiaries. The 10% value test does not apply to certain “straight debt” and other excluded securities, as described in the Code, including but not limited to any loan to an individual or an estate, any obligation to pay rents from real property and any security issued by a REIT. In addition, (a) a REIT's interest as a partner in a partnership is not considered a security for purposes of applying the 10% value test; (b) any debt instrument issued by a partnership (other than straight debt or other excluded security) will not be considered a security issued by the partnership if at least 75% of the partnership's gross income is derived from sources that would qualify for the 75% REIT gross income test; and (c) any debt instrument issued by a partnership (other than straight debt or other excluded security) will not be considered a security issued by the partnership to the extent of the REIT's interest as a partner in the partnership.

For purposes of the 10% value test, “straight debt” means a written unconditional promise to pay on demand on a specified date a sum certain in money if (i) the debt is not convertible, directly or indirectly, into stock, (ii) the interest rate and interest payment dates are not contingent on profits, the borrower's discretion, or similar factors other than certain contingencies relating to the timing and amount of principal and interest payments, as described in the Code and (iii) in the case of an issuer which is a corporation or a partnership, securities that otherwise would be considered straight debt will not be so considered if we, and any of our “controlled taxable REIT subsidiaries” as defined in the Code, hold any securities of the corporate or partnership issuer which (a) are not straight debt or other excluded securities (prior to the application of this rule), and (b) have an aggregate value greater than 1% of the issuer's outstanding securities (including, for the purposes of a partnership issuer, its interest as a partner in the partnership).

After initially meeting the asset tests at the close of any quarter, we will not lose our qualification as a REIT for failure to satisfy the asset tests at the end of a later quarter solely by reason of changes in asset values (including a failure caused solely by change in the foreign currency exchange rate used to value a foreign asset). If we fail to satisfy the asset tests because we acquire or increase our ownership interest in securities during a quarter, we can cure this failure by disposing of sufficient non-qualifying assets within 30 days after the close of that quarter. If we fail the 5% asset test, or the 10% vote or value asset tests at the end of any quarter and such failure is not cured within 30 days thereafter, we may dispose of sufficient assets (generally within six months after the last day of the quarter in which our identification of the failure to satisfy these asset tests occurred) to cure such a violation that does not exceed the lesser of 1% of our assets at the end of the relevant quarter or $10,000,000. If we fail any of the other asset tests or our failure of the 5% and 10% asset tests is in excess of the de minimis amount described above, as long as such failure was due to reasonable cause and not willful neglect, we may be permitted to avoid disqualification as a REIT, after the 30 day cure period, by taking steps including the disposition of sufficient assets to meet the asset test (generally within six months after the last day of the quarter in which our identification of the failure to satisfy the REIT asset test occurred) and paying a tax equal to the greater of $50,000 or the highest corporate income tax rate (currently 35%) of the net income generated by the non-qualifying assets during the period in which we failed to satisfy the asset test.

We expect that the assets and mortgage-related securities that we own generally will be qualifying assets for purposes of the 75% asset test. However, to the extent that we own non-REMIC collateralized mortgage obligations or other debt instruments secured by mortgage loans (rather than by real property) or secured by non-real estate assets, or debt securities issued by C corporations that are not secured by mortgages on real property, those securities may not be qualifying assets for purposes of the 75% asset test. In addition, we may purchase Agency RMBS through TBAs. There is no direct authority with respect to the qualification of TBAs as real estate assets or Government securities for purposes of the 75% asset test and we will not treat TBAs as such unless we receive advice of our counsel that TBAs should be treated as qualifying assets for purposes of the 75% asset test. As a result, our ability to purchase TBAs could be limited. Moreover, even if we were to receive advice of counsel as described in the preceding sentence, it is possible that the IRS could assert that TBAs are not qualifying assets in which case we could be subject to a penalty tax or fail to qualify as a REIT if such assets, when combined with other non-real estate assets, exceed 25% of our gross assets. We believe that our holdings of securities and other assets will be structured in a manner that will comply with the foregoing REIT asset requirements and intend to monitor compliance on an ongoing basis. There can be no assurance, however, that we will be successful in this effort. Moreover, values of some assets may not be susceptible to a precise determination and are subject to change in the future. Furthermore, the proper classification of an instrument as debt or equity for U.S. federal income tax purposes may be uncertain in some circumstances, which could affect the application of the REIT asset tests. Accordingly, there can be no assurance that the IRS will not contend that our interests in subsidiaries or in the securities of other issuers (including REIT issuers) cause a violation of the REIT asset tests.

In addition, we may enter into repurchase agreements under which we will nominally sell certain of our assets to a counterparty and simultaneously enter into an agreement to repurchase the sold assets. We believe that we will be treated for U.S. federal income tax purposes as the owner of the assets that are the subject of any such agreement notwithstanding that we may transfer record ownership of the assets to the counterparty during the term of the agreement. It is possible, however, that the IRS could assert that we did not own the assets during the term of the repurchase agreement, in which case we could fail to qualify as a REIT.

Annual Distribution Requirements

In order to qualify as a REIT, we are required to distribute dividends, other than capital gain dividends, to our stockholders in an amount at least equal to:

(a) the sum of:

90% of our “REIT taxable income” (computed without regard to the deduction for dividends paid and our net capital gains); and

90% of the net income (after tax), if any, from foreclosure property (as described below); minus

(b) the sum of specified items of non-cash income that exceeds a percentage of our income.

These distributions must be paid in the taxable year to which they relate or in the following taxable year if such distributions are declared in October, November or December of the taxable year, are payable to stockholders of record on a specified date in any such month and are actually paid before the end of January of the following year. Such distributions are treated as both paid by us and received by each stockholder on December 31 of the year in which they are declared. In addition, at our election, a distribution for a taxable year may be declared before we timely file our tax return for the year and be paid with or before the first regular dividend payment after such declaration, provided that such payment is made during the 12-month period following the close of such taxable year. These distributions are taxable to our stockholders in the year in which paid, even though the distributions relate to our prior taxable year for purposes of the 90% distribution requirement.

In order for distributions to be counted towards our distribution requirement and to give rise to a tax deduction by us, they must not be “preferential dividends.” A dividend is not a preferential dividend if it is pro rata among all outstanding shares of stock within a particular class and is in accordance with the preferences among different classes of stock as set forth in the organizational documents.

To the extent that we distribute at least 90%, but less than 100%, of our “REIT taxable income,” as adjusted, we will be subject to tax at ordinary corporate tax rates on the retained portion. In addition, we may elect to retain, rather than distribute, our net long-term capital gains and pay tax on such gains. In this case, we could elect to have our stockholders include their proportionate share of such undistributed long-term capital gains in income and receive a corresponding credit for their proportionate share of the tax paid by us. Our stockholders would then increase the adjusted basis of their stock in us by the difference between the designated amounts included in their long-term capital gains and the tax deemed paid with respect to their proportionate shares.

If we fail to distribute during each calendar year at least the sum of (a) 85% of our REIT ordinary income for such year, (b) 95% of our REIT capital gain net income for such year and (c) any undistributed taxable income from prior periods, we will be subject to a 4% excise tax on the excess of such required distribution over the sum of (x) the amounts actually distributed (taking into account excess distributions from prior periods) and (y) the amounts of income retained on which we have paid corporate income tax. We intend to make timely distributions so that we are not subject to the 4% excise tax.

It is possible that we, from time to time, may not have sufficient cash to meet the distribution requirements due to timing differences between (a) the actual receipt of cash, including receipt of distributions from our subsidiaries and (b) the inclusion of items in income by us for U.S. federal income tax purposes. For example, we may acquire debt instruments or notes whose face value may exceed its issue price as determined for U.S. federal income tax purposes (such excess, “original issue discount,” or OID), such that we will be required to include in our income a portion of the OID each year that the instrument is held before we receive any corresponding cash. In the event that such timing differences occur, in order to meet the distribution requirements, it might be necessary to arrange for short-term, or possibly long-term, borrowings or to pay dividends in the form of taxable in-kind distributions of property, including taxable stock dividends. In the case of a taxable stock dividend, stockholders would be required to include the dividend as income and would be required to satisfy the tax liability associated with the distribution with cash from other sources including sales of our common stock. Both a taxable stock distribution and sale of common stock resulting from such distribution could adversely affect the price of our common stock.

We may be able to rectify a failure to meet the distribution requirements for a year by paying “deficiency dividends” to stockholders in a later year, which may be included in our deduction for dividends paid for the earlier year. In this case, we may be able to avoid losing our qualification as a REIT or being taxed on amounts distributed as deficiency dividends. However, we will be required to pay interest and a penalty based on the amount of any deduction taken for deficiency dividends.

Recordkeeping Requirements

We are required to maintain records and request on an annual basis information from specified stockholders. These requirements are designed to assist us in determining the actual ownership of our outstanding stock and maintaining our qualifications as a REIT.

Prohibited Transactions

Net income we derive from a prohibited transaction is subject to a 100% tax. The term “prohibited transaction” generally includes a sale or other disposition of property (other than foreclosure property) that is held as inventory or primarily for sale to customers, in the ordinary course of a trade or business by a REIT, by a lower-tier partnership in which the REIT holds an equity interest or by a borrower that has issued a shared appreciation mortgage or similar debt instrument to the REIT. We intend to conduct our operations so that no asset owned by us or our pass-through subsidiaries will be held as inventory or primarily for sale to customers, and that a sale of any assets owned by us directly or through a pass-through subsidiary will not be in the ordinary course of business. However, whether property is held as inventory or “primarily for sale to customers in the ordinary course of a trade or business” depends on the particular facts and circumstances. No assurance can be given that any particular asset in which we hold a direct or indirect interest will not be treated as property held as inventory or primarily for sale to customers or that certain safe harbor provisions of the Code that prevent such treatment will apply. The 100% tax will not apply to gains from the sale of property that is held through a TRS or other taxable corporation, although such income will be subject to tax in the hands of the corporation at regular corporate income tax rates.

Foreclosure Property

Foreclosure property is real property and any personal property incident to such real property (1) that is acquired by a REIT as a result of the REIT having bid on the property at foreclosure or having otherwise reduced the property to ownership or possession by agreement or process of law after there was a default (or default was imminent) on a lease of the property or a mortgage loan held by the REIT and secured by the property, (2) for which the related loan or lease was acquired by the REIT at a time when default was not imminent or anticipated and (3) for which such REIT makes a proper election to treat the property as foreclosure property. REITs generally are subject to tax at the maximum corporate rate (currently 35%) on any net income from foreclosure property, including any gain from the disposition of the foreclosure property, other than income that would otherwise be qualifying income for purposes of the 75% gross income test. Any gain from the sale of property for which a foreclosure property election has been made will not be subject to the 100% tax on gains from prohibited transactions described above, even if the property would otherwise constitute inventory or dealer property in the hands of the selling REIT. We do not anticipate that we will receive any income from foreclosure property that is not qualifying income for purposes of the 75% gross income test, but, if we do receive any such income, we intend to elect to treat the related property as foreclosure property.

Failure to Qualify

In the event that we violate a provision of the Code that would result in our failure to qualify as a REIT, we may nevertheless continue to qualify as a REIT. Specified relief provisions will be available to us to avoid such disqualification if (1) the violation is due to reasonable cause and not due to willful neglect, (2) we pay a penalty of $50,000 for each failure to satisfy a requirement for qualification as a REIT and (3) the violation does not include a violation under the gross income or asset tests described above (for which other specified relief provisions are available). This cure provision reduces the instances that could lead to our disqualification as a REIT for violations due to reasonable cause. If we fail to qualify for taxation as a REIT in any taxable year and none of the relief provisions of the Code apply, we will be subject to tax, including any applicable alternative minimum tax, on our taxable income at regular corporate rates. Distributions to our stockholders in any year in which we are not a REIT will not be deductible by us, nor will they be required to be made. In this situation, to the extent of current and accumulated earnings and profits, and, subject to limitations of the Code, distributions to our stockholders will generally be taxable in the case of our stockholders who are individual U.S. stockholders (as defined below), at a maximum rate of 15% (through 2010), and dividends in the hands of our corporate U.S. stockholders may be eligible for the dividends received deduction. Unless we are entitled to relief under specific statutory provisions, we will also be disqualified from re-electing to be taxed as a REIT for the four taxable years following the year during which qualification was lost. It is not possible to state whether, in all circumstances, we will be entitled to statutory relief.

Taxation of Taxable U.S. Stockholders

This section summarizes the taxation of U.S. stockholders who hold our stock that are not tax-exempt organizations. For these purposes, a U.S. stockholder is a beneficial owner of our stock or warrants who for U.S. federal income tax purposes is:

a citizen or resident of the U.S.;

a corporation (including an entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the U.S. or of a political subdivision thereof (including the District of Columbia);

an estate whose income is subject to U.S. federal income taxation regardless of its source; or

any trust if (1) a U.S. court is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) it has a valid election in place to be treated as a U.S. person.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our stock, the U.S. federal income tax treatment of a partner generally will depend upon the status of the partner and the activities of the partnership. A partner of a partnership holding our common stock should consult its own tax advisor regarding the U.S. federal income tax consequences to the partner of the acquisition, ownership and disposition of our stock by the partnership.

Distributions

Provided that we qualify as a REIT, distributions made to our taxable U.S. stockholders out of our current or accumulated earnings and profits, and not designated as capital gain dividends, will generally be taken into account by them as ordinary dividend income and will not be eligible for the dividends received deduction for corporations. In determining the extent to which a distribution with respect to our common stock constitutes a dividend for U.S. federal income tax purposes, our earnings and profits will be allocated first to distributions with respect to our preferred stock, if any, and then to our common stock. Dividends received from REITs are generally not eligible to be taxed at the preferential qualified dividend income rates applicable (through 2010) to individual U.S. stockholders who receive dividends from taxable subchapter C corporations.

In addition, distributions from us that are designated as capital gain dividends will be taxed to U.S. stockholders as long-term capital gains, to the extent that they do not exceed our actual net capital gain for the taxable year, without regard to the period for which the U.S. stockholder has held our stock. To the extent that we elect under the applicable provisions of the Code to retain our net capital gains, U S stockholders will be treated as having received, for U.S. federal income tax purposes, our undistributed capital gains as well as a corresponding credit for taxes paid by us on such retained capital gains. U.S. stockholders will increase their adjusted tax basis in our common stock by the difference between their allocable share of such retained capital gain and their share of the tax paid by us. Corporate U.S. stockholders may be required to treat up to 20% of some capital gain dividends as ordinary income. Long-term capital gains are generally taxable at maximum federal rates of 15% (through 2010) in the case of U.S. stockholders who are individuals, and 35% for corporations. Capital gains attributable to the sale of depreciable real property held for more than 12 months are subject to a 25% maximum U.S. federal income tax rate for individual U.S. stockholders who are individuals, to the extent of previously claimed depreciation deductions.

Distributions in excess of our current and accumulated earnings and profits will not be taxable to a U.S. stockholder to the extent that they do not exceed the adjusted tax basis of the U.S. stockholder's shares in respect of which the distributions were made, but rather will reduce the adjusted tax basis of those shares. To the extent that such distributions exceed the adjusted tax basis of an individual U.S. stockholder's shares, they will be included in income as long-term capital gain, or short-term capital gain if the shares have been held for one year or less. In addition, any dividend declared by us in October, November or December of any year and payable to a U.S. stockholder of record on a specified date in any such month will be treated as both paid by us and received by the U.S. stockholder on December 31 of such year, provided that the dividend is actually paid by us before the end of January of the following calendar year.

With respect to U.S. stockholders who are taxed at the rates applicable to individuals, we may elect to designate a portion of our distributions paid to such U.S. stockholders as “qualified dividend income.” A portion of a distribution that is properly designated as qualified dividend income is taxable to non-corporate U.S. stockholders at the same rates as capital gain, provided that the U.S. stockholder has held the common stock with respect to which the distribution is made for more than 60 days during the 121-day period beginning on the date that is 60 days before the date on which such common stock became ex-dividend with respect to the relevant distribution. The maximum amount of our distributions eligible to be designated as qualified dividend income for a taxable year is equal to the sum of:

(a) the qualified dividend income received by us during such taxable year from non-REIT C corporations (including any TRS in which we may own an interest);

(b) the excess of any “undistributed” REIT taxable income recognized during the immediately preceding year over the U.S. federal income tax paid by us with respect to such undistributed REIT taxable income; and

(c) the excess of any income recognized during the immediately preceding year attributable to the sale of a built-in-gain asset that was acquired in a carry-over basis transaction from a non-REIT C corporation over the U.S. federal income tax paid by us with respect to such built-in gain.

Generally, dividends that we receive will be treated as qualified dividend income for purposes of (a) above if the dividends are received from a domestic C corporation (other than a REIT or a RIC), any TRS we may form, or a “qualifying foreign corporation” and specified holding period requirements and other requirements are met.

To the extent that we have available net operating losses and capital losses carried forward from prior tax years, such losses may reduce the amount of distributions that must be made in order to comply with the REIT distribution requirements. Such losses, however, are not passed through to U.S. stockholders and do not offset income of U.S. stockholders from other sources, nor do they affect the character of any distributions that are actually made by us, which are generally subject to tax in the hands of U.S. stockholders to the extent that we have current or accumulated earnings and profits.

Dispositions of Our Common Stock

In general, a U.S. stockholder will realize gain or loss upon the sale, redemption or other taxable disposition of our common stock in an amount equal to the difference between the sum of the fair market value of any property and the amount of cash received in such disposition and the U.S. stockholder's adjusted tax basis in the common stock at the time of the disposition. In general, a U.S. stockholder's adjusted tax basis will equal the U.S. stockholder's acquisition cost, increased by the excess of net capital gains deemed distributed to the U.S. stockholder (discussed above) less tax deemed paid on such gain and reduced by returns of capital. In general, capital gains recognized by individuals and other non-corporate U.S. stockholders upon the sale or disposition of shares of our common stock will be subject to a maximum U.S. federal income tax rate of 15% for taxable years through 2010, if our common stock is held for more than 12 months, and will be taxed at ordinary income rates (of up to 35% through 2010) if our common stock is held for 12 months or less. Gains recognized by U.S. stockholders that are corporations are subject to U.S. federal income tax at a maximum rate of 35%, whether or not classified as long-term capital gains. The IRS has the authority to prescribe, but has not yet prescribed, regulations that would apply a capital gain tax rate of 25% (which is generally higher than the long-term capital gain tax rates for non-corporate holders) to a portion of capital gain realized by a non- corporate holder on the sale of REIT stock or depositary shares that would correspond to the REIT's “unrecaptured Section 1250 gain.”

Holders are advised to consult with their tax advisors with respect to their capital gain tax liability. Capital losses recognized by a U.S. stockholder upon the disposition of our common stock held for more than one year at the time of disposition will be considered long-term capital losses, and are generally available only to offset capital gain income of the U.S. stockholder but not ordinary income (except in the case of individuals, who may offset up to $3,000 of ordinary income each year). In addition, any loss upon a sale or exchange of shares of our common stock by a U.S. stockholder who has held the shares for six months or less, after applying holding period rules, will be treated as a long-term capital loss to the extent of distributions received from us that were required to be treated by the U.S. stockholder as long-term capital gain.

Passive Activity Losses and Investment Interest Limitations

Distributions made by us and gain arising from the sale or exchange by a U.S. stockholder of our common stock will not be treated as passive activity income. As a result, U.S. stockholders will not be able to apply any “passive losses” against income or gain relating to our common stock. Distributions made by us, to the extent they do not constitute a return of capital, generally will be treated as investment income for purposes of computing the investment interest limitation. A U.S. stockholder that elects to treat capital gain dividends, capital gains from the disposition of stock or qualified dividend income as investment income for purposes of the investment interest limitation will be taxed at ordinary income rates on such amounts.

Taxation of Tax-Exempt U.S. Stockholders

U.S. tax-exempt entities, including qualified employee pension and profit sharing trusts and individual retirement accounts, generally are exempt from U.S. federal income taxation. However, they are subject to taxation on their unrelated business taxable income, which is referred to in this prospectus as UBTI. While many investments in real estate may generate UBTI, the IRS has ruled that dividend distributions from a REIT to a tax-exempt entity do not constitute UBTI. Based on that ruling, and provided that (1) a tax-exempt U.S. stockholder has not held our common stock as “debt financed property” within the meaning of the Code ( i.e., where the acquisition or holding of the property is financed through a borrowing by the tax-exempt stockholder), (2) our common stock is not otherwise used in an unrelated trade or business, and (3) we do not hold an asset that gives rise to excess inclusion income, distributions from us and income from the sale of our common stock generally should not give rise to UBTI to a tax-exempt U.S. stockholder.

Tax-exempt U.S. stockholders that are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, and qualified group legal services plans exempt from U.S. federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) and (c) (20) of the Code, respectively, are subject to different UBTI rules, which generally will require them to characterize distributions from us as UBTI unless they are able to properly claim a deduction for amounts set aside or placed in reserve for specific purposes so as to offset the income generated by its investment in our common stock. These prospective investors should consult their tax advisors concerning these “set aside” and reserve requirements.

In certain circumstances, a pension trust (1) that is described in Section 401(a) of the Code, (2) is tax exempt under Section 501(a) of the Code, and (3) that owns more than 10% of our stock could be required to treat a percentage of the dividends from us as UBTI if we are a “pension-held REIT.” We will not be a pension-held REIT unless (1) either (A) one pension trust owns more than 25% of the value of our stock, or (B) a group of pension trusts, each individually holding more than 10% of the value of our stock, collectively owns more than 50% of such stock; and (2) we would not have qualified as a REIT but for the fact that Section 856(h)(3) of the Code provides that stock owned by such trusts shall be treated, for purposes of the requirement that not more than 50% of the value of the outstanding stock of a REIT is owned, directly or indirectly, by five or fewer “individuals” (as defined in the Code to include certain entities), as owned by the beneficiaries of such trusts. Certain restrictions limiting ownership and transfer of our stock should generally prevent a tax-exempt entity from owning more than 10% of the value of our stock, or us from becoming a pension-held REIT.

Tax-exempt U.S. stockholders are urged to consult their tax advisors regarding the U.S. federal, state, local and foreign tax consequences of owning our stock.

Taxation of Non-U.S. Stockholders

The following is a summary of certain U.S. federal income tax consequences of the acquisition, ownership and disposition of our common stock applicable to non-U.S. stockholders of our common stock. For these purposes, a non-U.S. stockholder is a beneficial owner of our stock who is neither a U.S. stockholder nor an entity that is treated as a partnership for U.S. federal income tax purposes. The discussion is based on current law and is for general information only. It addresses only selective and not all aspects of U.S. federal income taxation of non-U.S. stockholders.

General

For most foreign investors, investment in a REIT that invests principally in mortgage loans and mortgage-backed securities is not the most tax-efficient way to invest in such assets. That is because receiving distributions of income derived from such assets in the form of REIT dividends subjects most foreign investors to withholding taxes that direct investment in those asset classes, and the direct receipt of interest and principal payments with respect to them, would not. The principal exceptions are foreign sovereigns and their agencies and instrumentalities, which may be exempt from withholding taxes on REIT dividends under the Code, and certain foreign pension funds or similar entities able to claim an exemption from withholding taxes on REIT dividends under the terms of a bilateral tax treaty between their country of residence and the United States.

Ordinary Dividends

The portion of dividends received by non-U.S. stockholders payable out of our earnings and profits that are not attributable to gains from sales or exchanges of U.S. real property interests and which are not effectively connected with a U.S. trade or business of the non-U.S. stockholder will generally be subject to U.S. federal withholding tax at the rate of 30.0%, unless reduced or eliminated by an applicable income tax treaty. Under some treaties, however, lower rates generally applicable to dividends do not apply to dividends from REITs. In addition, any portion of the dividends paid to non-U.S. stockholders that are treated as excess inclusion income will not be eligible for exemption from the 30.0% withholding tax or a reduced treaty rate. In the case of a taxable stock dividend with respect to which any withholding tax is imposed, we may have to withhold or dispose of part of the shares otherwise distributable in such dividend and use such shares or the proceeds of such disposition to satisfy the withholding tax imposed.

In general, non-U.S. stockholders will not be considered to be engaged in a U.S. trade or business solely as a result of their ownership of our stock. In cases where the dividend income from a non-U.S. stockholder's investment in our common stock is, or is treated as, effectively connected with the non-U.S. stockholder's conduct of a U.S. trade or business, the non-U.S. stockholder generally will be subject to U.S. federal income tax at graduated rates, in the same manner as U.S. stockholders are taxed with respect to such dividends, and may also be subject to the 30.0% branch profits tax on the income after the application of the income tax in the case of a non-U.S. stockholder that is a corporation.

Non-Dividend Distributions

Unless (A) our common stock constitutes a U.S. real property interest (or USRPI) or (B) either (1) the non-U.S. stockholder's investment in our common stock is effectively connected with a U.S. trade or business conducted by such non-U.S. stockholder (in which case the non-U.S. stockholder will be subject to the same treatment as U.S. stockholders with respect to such gain) or (2) the non-U.S. stockholder is a nonresident alien individual who was present in the U.S. for 183 days or more during the taxable year and has a “tax home” in the U.S. (in which case the non-U.S. stockholder will be subject to a 30.0% tax on the individual's net capital gain for the year), distributions by us which are not dividends out of our earnings and profits will not be subject to U.S. federal income tax. If we cannot determine at the time at which a distribution is made whether or not the distribution will exceed current and accumulated earnings and profits, the distribution will be subject to withholding at the rate applicable to dividends. However, the non-U.S. stockholder may seek a refund from the IRS of any amounts withheld if it is subsequently determined that the distribution was, in fact, in excess of our current and accumulated earnings and profits. If our common stock constitutes a USRPI, as described below, distributions by us in excess of the sum of our earnings and profits plus the non-U.S. stockholder's adjusted tax basis in its common stock will be taxed under the Foreign Investment in Real Property Tax Act of 1980 (or FIRPTA) at the rate of tax, including any applicable capital gains rates, that would apply to a U.S. stockholder of the same type (e.g., an individual or a corporation, as the case may be), and the collection of the tax will be enforced by a refundable withholding at a rate of 10% of the amount realized by the stockholder less any amount treated as ordinary dividend income.

Capital Gain Dividends

Under FIRPTA, a distribution made by us to a non-U.S. stockholder, to the extent attributable to gains from dispositions of USRPIs held by us directly or through pass-through subsidiaries (or USRPI capital gains), will be considered effectively connected with a U.S. trade or business of the non-U.S. stockholder and will be subject to U.S. federal income tax at the rates applicable to U.S. stockholders, without regard to whether the distribution is designated as a capital gain dividend. In addition, we will be required to withhold tax equal to 35% of the amount of capital gain dividends to the extent the dividends constitute USRPI capital gains. Distributions subject to FIRPTA may also be subject to a 30.0% branch profits tax in the hands of a non-U.S. holder that is a corporation. However, the 35% withholding tax will not apply to any capital gain dividend with respect to any class of our stock which is regularly traded on an established securities market located in the U.S. if the non-U.S. stockholder did not own more than 5% of such class of stock at any time during the one-year period ending on the date of such dividend. Instead any capital gain dividend will be treated as a distribution subject to the rules discussed above under “- Taxation of Non-U.S. Stockholders - Ordinary Dividends.” Also, the branch profits tax will not apply to such a distribution. A distribution is not a USRPI capital gain if we held the underlying asset solely as a creditor, although the holding of a shared appreciation mortgage loan would not be solely as a creditor. Capital gain dividends received by a non-U.S. stockholder from a REIT that are not USRPI capital gains are generally not subject to U.S. federal income or withholding tax, unless either (1) the non-U.S. stockholder's investment in our common stock is effectively connected with a U.S. trade or business conducted by such non-U.S. stockholder (in which case the non-U.S. stockholder will be subject to the same treatment as U.S. stockholders with respect to such gain) or (2) the non-U.S. stockholder is a nonresident alien individual who was present in the U.S. for 183 days or more during the taxable year and has a “tax home” in the U.S. (in which case the non-U.S. stockholder will be subject to a 30.0% tax on the individual's net capital gain for the year).

Dispositions of Our Common Stock

Unless our common stock constitutes a USRPI, a sale of the stock by a non-U.S. stockholder generally will not be subject to U.S. federal income taxation under FIRPTA. The stock will not be treated as a USRPI if less than 50% of our assets throughout a prescribed testing period consist of interests in real property located within the U.S., excluding, for this purpose, interests in real property solely in a capacity as a creditor. We do not expect that more than 50% of our assets will consist of interests in real property located in the U.S., excluding interests solely in a creditor capacity.

Even if our shares of common stock otherwise would be a USRPI under the foregoing test, our shares of common stock will not constitute a USRPI if we are a “domestically controlled REIT.” A domestically controlled REIT is a REIT in which, at all times during a specified testing period (generally the lesser of the five year period ending on the date of disposition of our shares of common stock or the period of our existence), less than 50% in value of our outstanding shares of common stock is held directly or indirectly by non-U.S. stockholders. We believe we will be a domestically controlled REIT and, therefore, the sale of our common stock should not be subject to taxation under FIRPTA. However, because our stock will be widely held, we cannot assure our investors that we will be a domestically controlled REIT. Even if we do not qualify as a domestically controlled REIT, a non-U.S. stockholder's sale of our common stock nonetheless will generally not be subject to tax under FIRPTA as a sale of a USRPI, provided that (a) our common stock owned is of a class that is “regularly traded,” as defined by the applicable Treasury regulation, on an established securities market, and (b) the selling non-U.S. stockholder owned, actually or constructively, 5% or less of our outstanding stock of that class at all times during a specified testing period.

If gain on the sale of our common stock were subject to taxation under FIRPTA, the non-U.S. stockholder would be subject to the same treatment as a U.S. stockholder with respect to such gain, subject to applicable alternative minimum tax and a special alternative minimum tax in the case of non-resident alien individuals, and the purchaser of the stock could be required to withhold 10% of the purchase price and remit such amount to the IRS.

Gain from the sale of our common stock that would not otherwise be subject to FIRPTA will nonetheless be taxable in the U.S. to a non-U.S. stockholder in two cases: (a) if the non-U.S. stockholder's investment in our common stock is effectively connected with a U.S. trade or business conducted by such non-U.S. stockholder, the non-U.S. stockholder will be subject to the same treatment as a U.S. stockholder with respect to such gain, or (b) if the non-U.S. stockholder is a nonresident alien individual who was present in the U.S. for 183 days or more during the taxable year and has a “tax home” in the U.S., the nonresident alien individual will be subject to a 30.0% tax on the individual's capital gain.

Backup Withholding and Information Reporting

We will report to our U.S. stockholders and the IRS the amount of dividends paid during each calendar year and the amount of any tax withheld. Under the backup withholding rules, a U.S. stockholder may be subject to backup withholding with respect to dividends paid unless the holder is a corporation or comes within other exempt categories and, when required, demonstrates this fact or provides a taxpayer identification number or social security number, certifies as to no loss of exemption from backup withholding and otherwise complies with applicable requirements of the backup withholding rules. A U.S. stockholder that does not provide his or her correct taxpayer identification number or social security number may also be subject to penalties imposed by the IRS. In addition, we may be required to withhold a portion of capital gain distributions to any U.S. stockholder who fails to certify its non-foreign status.

We must report annually to the IRS and to each non-U.S. stockholder the amount of dividends paid to such holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which the non-U.S. stockholder resides under the provisions of an applicable income tax treaty. A non-U.S. stockholder may be subject to backup withholding unless applicable certification requirements are met.

Payment of the proceeds of a sale of our common stock within the U.S. is subject to both backup withholding and information reporting unless the beneficial owner certifies under penalties of perjury that it is a non-U.S. stockholder (and the payor does not have actual knowledge or reason to know that the beneficial owner is a U.S. person) or the holder otherwise establishes an exemption. Payment of the proceeds of a sale of our common stock conducted through certain U.S. related financial intermediaries is subject to information reporting (but not backup withholding) unless the financial intermediary has documentary evidence in its records that the beneficial owner is a non-U.S. stockholder and specified conditions are met or an exemption is otherwise established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against such holder's U.S. federal income tax liability provided the required information is furnished to the IRS.

State, Local and Foreign Taxes

We and our stockholders may be subject to state, local or foreign taxation in various jurisdictions, including those in which we or they transact business, own property or reside. The state, local or foreign tax treatment of us and our stockholders may not conform to the U.S. federal income tax treatment discussed above. Any foreign taxes incurred by us would not pass through to stockholders as a credit against their U.S. federal income tax liability. Prospective stockholders should consult their tax advisors regarding the application and effect of state, local and foreign income and other tax laws on an investment in our common stock.

Legislative or Other Actions Affecting REITs

The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department. No assurance can be given as to whether, when, or in what form, U.S. federal income tax laws applicable to us and our stockholders may be enacted. Changes to the U.S. federal income tax laws and interpretations of U.S. federal income tax laws could adversely affect an investment in our shares of common stock.

Tax Opinion

PLAN OF DISTRIBUTION

This prospectus covers (i) 32,500,000 shares of common stock that may be issued upon exercise of warrants by warrantholders and (ii) the resale by the selling securityholders of up to 7,500,000 warrants and/or up to 7,500,000 shares of common stock that may be issued upon exercise of those warrants.

With respect to the shares of common stock issuable upon exercise of the 32,500,000 warrants, pursuant to the terms of the warrants as set forth in the warrant agreement, the shares will be distributed to those warrant holders who surrender the certificates representing their warrants and provide payment of the exercise price through their brokers to our warrant agent, Continental Stock Transfer & Trust Company, who will receive such payments on our behalf.

With respect to the 7,500,000 warrants and shares subject to resale, we have registered the warrants and shares for resale to provide the selling securityholders with freely tradable securities. However, registration of the warrants and shares of common stock does not necessarily mean that the selling securityholders will offer or sell any of the warrants or shares. We will not receive any proceeds from the offering or sale of warrants or shares by the selling securityholders.

Any selling securityholders may from time to time, in one or more transactions, sell all or a portion of the warrants and shares registered hereby on the NYSE Amex, in the over-the-counter market, on any other national securities exchange on which the warrants or shares are listed or traded, in negotiated transactions, in underwritten transactions or otherwise, at prices then prevailing or related to the then current market price or at negotiated prices. The offering price of the warrants and shares registered hereby from time to time will be determined by the selling securityholders and, at the time of determination, may be higher or lower than the market price of the warrants and common stock on the NYSE Amex, as applicable. In connection with an underwritten offering, underwriters or agents may receive compensation in the form of discounts, concessions or commissions from a selling securityholder or from purchasers of warrants or shares registered hereby for whom they may act as agents, and underwriters may sell warrants or shares registered hereby to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agents. In compliance with the guidelines of the Financial Industry Regulatory Authority, or FINRA, the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of any offering pursuant to this prospectus and any applicable prospectus supplement or pricing supplement, as the case may be. Under agreements that may be entered into by ARMOUR, underwriters, dealers and agents who participate in the distribution of warrants or shares registered hereby may be entitled to indemnification by us against specific liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such underwriters, dealers or agents may be required to make in respect thereof. The warrants and shares registered hereby may be sold directly or through broker-dealers acting as principal or agent, or pursuant to a distribution by one or more underwriters on a firm commitment or best-efforts basis. The methods by which the warrants and shares registered hereby may be sold include: (A) a block trade in which the broker-dealer so engaged will attempt to sell the warrants or shares registered hereby as agent but may position and resell a portion of the block as principal to facilitate the transaction; (B) a purchase by a broker-dealer as principal and resale by the broker-dealer for its account pursuant to this prospectus; (C) an ordinary brokerage transaction and a transaction in which the broker solicits purchasers; (D) an exchange distribution in accordance with the rules of the NYSE Amex; (E) privately negotiated transactions; and (F) an underwritten transaction.

Any selling securityholder that is identified as a broker-dealer will be deemed to be an “underwriter” within the meaning of Section 2(11) of the Securities Act, unless such selling securityholder obtained the warrants as compensation for services. In addition, any affiliate of a broker-dealer will be deemed to be an “underwriter” within the meaning of Section 2(11) of the Securities Act, unless such selling securityholder purchased in the ordinary course of business and, at the time of its purchase of the warrants to be resold, did not have any agreements or understandings, directly or indirectly, with any person to distribute the warrants. As a result, any profits on the sale of the warrants or common stock by selling securityholders who are deemed to be “underwriters” and any discounts, commissions or concessions received by any such broker-dealers who are deemed to be “underwriters” will be deemed to be underwriting discounts and commissions under the Securities Act.

To the extent required, upon being notified by a selling securityholder that any arrangement has been entered into with any agent, underwriter or broker-dealer for the sale of the warrants or shares of common stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by any agent, underwriter or broker-dealer(s), the name(s) of the selling securityholder(s) and of the participating agent, underwriter or broker-dealer(s), specific warrants or common stock to be sold, the respective purchase prices and public offering prices, any applicable commissions or discounts, and other facts material to the transaction will be set forth in a supplement to this prospectus or a post-effective amendment to the registration statement of which this prospectus is a part, as appropriate.

When a selling securityholder elects to make a particular offer of warrants or shares registered hereby, a prospectus supplement, if required, will be distributed which will identify any underwriters, dealers or agents and any discounts, commissions and other terms constituting compensation from the selling securityholder and any other required information.

In order to comply with state securities laws, if applicable, the warrants and shares registered hereby may be sold only through registered or licensed brokers or dealers. In addition, in specific states, the warrants and shares registered hereby may not be sold unless they have been registered or qualified for sale in such state or an exemption from such registration or qualification requirement is available and is complied with.

We have agreed to pay all costs and expenses incurred in connection with the registration under the Securities Act of the warrants and shares being registered hereby, including, without limitation, all registration and filing fees, printing expenses and fees and disbursements of our counsel and our accountants. The selling securityholders will pay any brokerage fees and commissions, fees and disbursements of legal counsel for the selling securityholders and stock transfer and other taxes attributable to the sale of the warrants and shares registered hereby.

Item 15. Indemnification of Directors and Officers.

Maryland law permits a Maryland corporation to include in its charter a provision eliminating the liability of its directors and officers to the corporation and its stockholders for money damages, except for liability resulting from (1) actual receipt of an improper benefit or profit in money, property or services or (2) active and deliberate dishonesty established by a final judgment as being material to the cause of action. Our charter contains such a provision that eliminates such liability to the maximum extent permitted by Maryland law.

The Maryland General Corporation Law, or MGCL, requires us (unless our charter provides otherwise, which our charter does not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made or threatened to be made a party by reason of his or her service in that capacity. The MGCL permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may by made or threatened to be made a party by reason of their services in those or other capacities unless it is established that:

the act or omission of the director or officer was material to the matter giving rise to the proceeding and (1) was committed in bad faith or (2) was the result of active and deliberate dishonesty;

the director or officer actually received an improper personal benefit in money, property or services; or

in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful.

II-1

In addition, the MGCL permits a corporation to advance reasonable expenses to a director or officer upon the corporation's receipt of:

a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by the corporation; and

any present or former director or officer who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity; or

any individual who, while a director or officer of our company and at our request, serves or has served another corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan or other enterprise as a director, officer, partner or trustee of such corporation, real estate investment trust, partnership, joint venture, trust, employee benefit plan or other enterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity.

Item 16. Exhibits.

See the Exhibits Index, which is incorporated into this registration statement by reference.

Item 17. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1)

To file, during any period in which offers or sales are being made, a post−effective amendment to this registration statement:

(i)

To include any prospectus required by section 10(a)(3) of the Securities Act of 1933.

II-2

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post−effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post−effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post−effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)

To remove from registration by means of a post−effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)

That, for purposes of determining liability under the Securities Act of 1933 to any purchaser:

As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5)

That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b)

The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)

The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305 (b) (2) of the Act.

II-4

(d)

The undersigned registrant hereby further undertakes that:

(1)

For purposes of determining any liability under the Securities Act of 1933 the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4), or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2)

For the purposes of determining any liability under the Securities Act, each post−effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
