CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

        This prospectus supplement, the accompanying prospectus and the documents we incorporate herein and therein by reference contain certain forward-looking statements, including, without limitation, statements concerning our operations, economic performance and financial condition. These forward-looking statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are developed by combining currently available information with our beliefs and assumptions and are generally identified by the words "believe," "expect," "anticipate" and other similar expressions.

        These forward-looking statements are based largely on our current beliefs, assumptions and expectations of our future performance taking into account all information currently available to us. These beliefs, assumptions and expectations can change as a result of many possible events or factors, not all of which are known to us or within our control, and which could materially affect actual results, performance or achievements. Factors that may cause actual results to vary from our forward-looking statements include, but are not limited to:

•

factors described in our Annual Report on Form 10-K for the year ended December 31, 2011, including those set forth under the captions "Risk Factors" and "Business" and in our other periodic reports filed with the SEC and incorporated by reference herein;

•

potential mismatches in the timing of asset repayments and the maturity of the associated financing agreements;



•

national and local economic and business conditions;



•

general and local commercial real estate property conditions;



•

changes in federal government policies;



•

changes in federal, state and local governmental laws and regulations;



•

increased competition from entities engaged in mortgage lending;



•

•

factors associated with the ownership of residential real estate assets acquired by us directly or indirectly in settlement of loans, or residential REO, and held for lease and potentially for sale, including: macroeconomic shifts in demand for, and competition in the supply of, residential rental properties; the inability to lease or re-lease properties to tenants on attractive terms or at all; the failure of tenants to pay rent when due or otherwise perform their lease obligations; unanticipated repairs, capital expenditures or other costs; uninsured damages; increases in property taxes and insurance costs; our ability to dispose of the residential REO in a timely manner in response to changes in market conditions; and potential tax liabilities owed, and limitations imposed, upon disposition of the residential REO; and

RISK FACTORS

        Investing in our common stock involves risks. You should carefully read and consider the risks described below as well as the risks described in the section entitled "Item 1A—Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2011, and in our other periodic reports filed with the SEC, and incorporated by reference into this prospectus supplement and the accompanying prospectus, as well as the other information contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus, including risks described above in "Cautionary Statement Regarding Forward-Looking Statements," before making a decision to invest in our common stock. Each of these risks could materially and adversely affect our business, financial condition, results of operations, liquidity and prospects, and could result in a partial or complete loss of your investment.

Risks Related to This Offering

The market price and trading volume of our common stock could be volatile and the market price of our common stock could decline, resulting in a substantial or complete loss of your investment.

        The stock markets, including the NYSE, which is the exchange on which we list our common stock, have experienced significant price and volume fluctuations. Overall weakness in the economy and other factors have recently contributed to extreme volatility of the equity markets generally, including the market price of our common stock. As a result, the market price of our common stock has been and may continue to be volatile, and investors in our common stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. Some of the factors that could negatively affect our stock price or result in fluctuations in the price or trading volume of our common stock include:

•

our actual or projected operating results, financial condition, cash flows and liquidity, or changes in business strategy or prospects;



•

actual or perceived conflicts of interest with our manager or Starwood Capital Group and individuals, including our executives;



•

equity issuances by us, or share resales by our stockholders, or the perception that such issuances or resales may occur;



•

actual or anticipated accounting problems;



•

publication of research reports about us or the real estate industry;



•

changes in market valuations of similar companies;



•

adverse market reaction to the level of leverage we employ;



•

additions to or departures of our manager's or Starwood Capital Group's key personnel;



•

speculation in the press or investment community;



•

our failure to meet, or the lowering of, our earnings' estimates or those of any securities analysts;



•

increases in market interest rates, which may lead investors to demand a higher distribution yield for our common stock and would result in increased interest expenses on our debt;



•

failure to maintain our REIT qualification;



•

uncertainty regarding our exemption from the Investment Company Act;



•

price and volume fluctuations in the stock market generally; and

S-5

Table of Contents

•

general market and economic conditions, including the current state of the credit and capital markets.

        In the past, securities class action litigation has often been instituted against companies following periods of volatility in their share price. This type of litigation could result in substantial costs and divert our management's attention and resources.

There may be future dilution of our common stock as a result of additional issuances of our securities, which could adversely impact our stock price.

        Our board of directors is authorized under our charter to, among other things, authorize the issuance of additional shares of our common stock or the issuance of shares of preferred stock or securities convertible or exchangeable into equity securities, without stockholder approval. We may issue such additional equity or convertible or exchangeable securities to raise additional capital. However, because our decision to issue additional equity or convertible or exchangeable securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Holders of shares of our common stock have no preemptive rights that entitle them to purchase their pro rata share of any offering of shares of any class or series. Therefore, it may not be possible for existing stockholders to participate in such future share issuances, which may dilute the existing stockholders' interests in us. Additionally, any convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our common stock. Also, we cannot predict the effect, if any, of future sales of our common stock, or the availability of shares for future sales, on the market price of our common stock. Sales of substantial amounts of common stock or the perception that such sales could occur may adversely affect the prevailing market price for our common stock.

We have not established a minimum distribution payment level and no assurance can be given that we will be able to make distributions to our stockholders in the future at current levels or at all.

        We are generally required to distribute to our stockholders at least 90% of our taxable income each year for us to qualify as a REIT under the Internal Revenue Code of 1986, as amended, or the Code, which requirement we currently intend to satisfy through quarterly distributions of all or substantially all of our REIT taxable income in such 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 contained in or incorporated by reference into this prospectus supplement and the accompanying prospectus. Although we have made, and anticipate continuing to make, quarterly distributions to our stockholders, our board of directors has the sole discretion to determine the timing, form and amount of any future distributions to our stockholders, and such determination will depend on our earnings, our financial condition, debt covenants, maintenance of our REIT qualification and other factors as our board of directors may deem relevant from time to time. We believe that a change in any one of the following factors could adversely affect our results of operations and impair our ability to continue to pay distributions to our stockholders:

•

the profitability of the investment of the net proceeds from our equity offerings;



•

our ability to make profitable investments;



•

margin calls or other expenses that reduce our cash flow;



•

defaults in our asset portfolio or decreases in the value of our portfolio; and



•

the fact that anticipated operating expense levels may not prove accurate, as actual results may vary from estimates.

S-6

Table of Contents

        As a result, no assurance can be given that we will be able to continue to make distributions to our stockholders in the future or that the level of any future distributions we do make to our stockholders will achieve a market yield or increase or even be maintained over time, any of which could materially and adversely affect us.

        In addition, distributions that we make to our stockholders are generally taxable to our stockholders as ordinary income. However, a portion of our distributions may be designated by us as long-term capital gains to the extent that they are attributable to capital gain income recognized by us or may constitute a return of capital to the extent that they exceed our earnings and profits as determined for tax purposes. A return of capital is not taxable, but has the effect of reducing the basis of a stockholder's investment in our common stock.

Investing in our common stock may involve a high degree of risk.

        The investments that we make in accordance with our investment objectives may result in a high amount of risk, resulting in a complete loss of principal, when compared to alternative investment options. Our investments may be highly speculative and aggressive, and therefore an investment in our common stock may not be suitable for someone with lower risk tolerance.

USE OF PROCEEDS

        We expect that the net proceeds from this offering will be approximately $             million after deducting our estimated expenses (or approximately $             million if the underwriters' option to purchase additional shares is exercised in full). We intend to use the net proceeds from this offering to originate and to purchase additional commercial mortgage loans and other assets. We may also use a portion of the net proceeds for other general corporate purposes, including, but not limited to, the payment of liabilities and other working capital needs.

SUPPLEMENTAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

        The following discussion supplements the discussion under the section entitled "U.S. Federal Income Tax Considerations" in the accompanying prospectus. Terms used in this section but not defined in this section have the meanings ascribed to them elsewhere in this prospectus supplement or in the section entitled "U.S. Federal Income Tax Considerations" in the accompanying prospectus. You should refer to the discussion in the accompanying prospectus under "U.S. Federal Income Tax Considerations" for a discussion of the tax consequences of our election to be taxed as a REIT and additional information regarding the tax consequences to owners of shares of our common stock.

Recent Legislation

        On December 17, 2010, the President signed the Tax Relief, Unemployment Insurance Reauthorization and Job Creation Act, which we refer to as the 2010 Tax Relief Act. The 2010 Tax Relief Act continues the 35% maximum tax rate on ordinary income and the 15% maximum tax rate for long-term capital gains and qualified dividend income for taxable years through December 31, 2012, for individual taxpayers, trusts and estates. For taxable years beginning after December 31, 2012, the capital gains tax rate is scheduled to increase to 20%, and the rate applicable to qualified dividends is scheduled to increase to the tax rate then applicable to ordinary income. In addition, the backup withholding rate remains at 28% through December 31, 2012. Because we are not generally subject to U.S. federal income tax on the portion of our REIT taxable income or capital gains distributed to our stockholders, our dividends will generally not be eligible for the 15% tax rate on qualified dividends. As a result, our ordinary REIT dividends will continue to be taxed at the higher tax rates applicable to ordinary income. However, the 15% tax rate for long-term capital gains and qualified dividends will generally apply to: (i) long-term capital gains, if any, recognized on the disposition of our shares; (ii) our distributions designated as long-term capital gain dividends (except to the extent attributable to "unrecaptured Section 1250 gain," in which case such distributions would continue to be subject to a 25% tax rate); (iii) our dividends attributable to dividends received by us from non-REIT corporations, such as taxable REIT subsidiaries; and (iv) our dividends to the extent attributable to income upon which we have paid corporate income tax (e.g., to the extent that we distribute less than 100% of our taxable income).

HIRE Act

        Legislation enacted in 2010 will generally impose a 30% withholding tax on dividends on shares of our common stock and the gross proceeds of a disposition of shares of our common stock paid to (i) a foreign financial institution (as that term is defined in Section 1471(d)(4) of the Code) unless that foreign financial institution enters into an agreement with the U.S. Treasury Department to collect and disclose information regarding U.S. account holders of that foreign financial institution (including certain account holders that are foreign entities that have U.S. owners) and satisfies other requirements, and (ii) specified other non-U.S. entities unless such an entity provides the payor with a certification identifying the direct and indirect U.S. owners of the entity and complies with other requirements. Under specified circumstances, a Non-U.S. Holder of shares of our common stock may be eligible for refunds or credits of those taxes. Proposed Treasury Regulations have been issued providing that the withholding provisions described above will apply to payments of dividends on shares of our common stock made on or after January 1, 2014 and to payments of gross proceeds of a disposition of shares of our common stock on or after January 1, 2015. You are encouraged to consult with your own tax advisor regarding the possible implications of this legislation on your investment in shares of our common stock.

UNDERWRITING

        Citigroup Global Markets Inc. and Wells Fargo Securities, LLC are acting as underwriters of this offering. Subject to the terms and conditions stated in the underwriting agreement, each underwriter named below has severally agreed to purchase, and we have agreed to sell to that underwriter, the number of shares set forth opposite the underwriter's name.

        The underwriting agreement provides that the obligations of the underwriters to purchase the shares included in this offering are subject to approval of legal matters by counsel and to other conditions. The underwriters are obligated to purchase all the shares (other than those covered by the option to purchase additional shares described below) if they purchase any of the shares.

        The underwriters have agreed to purchase the shares of common stock from us at a price of $            per share, which will result in net proceeds to us, after deducting estimated expenses related to this offering, of approximately $             million assuming no exercise of the option to purchase additional shares granted to the underwriters, and $             million assuming full exercise of the option.

        The underwriters propose to offer the shares of common stock offered hereby from time to time for sale in one or more transactions on the NYSE, in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices, subject to receipt of acceptance by them and subject to their right to reject any order in whole or in part. The underwriters may effect such transactions by selling the shares to or through dealers and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or purchasers of shares for whom they may act as agents or to whom they may sell as principal. The difference between the price at which the underwriters purchase shares and the price at which the underwriters resell such shares, which may include a commission equivalent of up to $.05 per share, may be deemed underwriting compensation.

        We estimate that our total expenses for this offering will be approximately $1.0 million.

        If the underwriters sell more shares than the total number set forth in the table above, we have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase up to 3,000,000 additional shares at $            per share. To the extent the option is exercised, each underwriter must purchase a number of additional shares approximately proportionate to that underwriter's initial purchase commitment. Any shares issued or sold under the option will be issued and sold on the same terms and conditions as the other shares that are the subject of this offering.

        We, each of our officers and directors, our manager, each of our manager's officers and SPT Investment, LLC have agreed that, for a period of 60 days from the date of this prospectus supplement, subject to certain exceptions, we and they will not, without the prior written consent of Citigroup Global Markets Inc. and Wells Fargo Securities, LLC, dispose of or hedge any shares or any securities convertible into or exchangeable for our common stock. Citigroup Global Markets Inc. and Wells Fargo Securities, LLC, in their sole discretion, may release any of the securities subject to these lock-up agreements at any time without notice. If (i) during the last 17 days of the 60-day restricted period, we issue an earnings release or material news or a material event relating to our company occurs; or (ii) prior to the expiration of the 60-day restricted period, we announce that we will release earnings results during the 16-day period beginning on the last day of the 60-day restricted period, the restrictions described above shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. However, such extension will not apply if, within three business days prior to the 15th calendar day

S-11

Table of Contents

before the last day of the restricted period, we deliver a certificate signed by our Chief Executive Officer or Chief Financial Officer, certifying that (i) our shares of common stock are "actively traded securities" as defined in Regulation M, and (ii) we meet the requirements set forth in Rule 139 under the Securities Act of 1933, as amended, or the Securities Act, for the publication of issuer-specific research reports.

        The shares are listed on the NYSE under the symbol "STWD."

        In connection with this offering, the underwriters may purchase and sell shares in the open market. Purchases and sales in the open market may include short sales, purchases to cover short positions, which may include purchases pursuant to the option to purchase additional shares, and stabilizing purchases.

•

Short sales involve secondary market sales by the underwriters of a greater number of shares than they are required to purchase in this offering.

•

"Covered" short sales are sales of shares in an amount up to the number of shares represented by the underwriters' option to purchase additional shares.

•

"Naked" short sales are sales of shares in an amount in excess of the number of shares represented by the underwriters' option to purchase additional shares.

•

Covering transactions involve purchases of shares either pursuant to the option to purchase additional shares or in the open market after the distribution has been completed in order to cover short positions.

•

To close a naked short position, the underwriters must purchase shares in the open market after the distribution has been completed. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in this offering.

•

To close a covered short position, the underwriters must purchase shares in the open market after the distribution has been completed or must exercise the option to purchase additional shares. In determining the source of shares to close the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option to purchase additional shares.

•

Stabilizing transactions involve bids to purchase shares so long as the stabilizing bids do not exceed a specified maximum.

        Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the shares. They may also cause the price of the shares to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions on the NYSE, in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

        We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

Conflicts of Interest

        In the ordinary course of their businesses, the underwriters and/or their respective affiliates may have, from time to time, (i) performed commercial banking, investment banking and/or financial advisory services for us, for which they have received customary fees and reimbursement of expenses, and (ii) engaged in various financial transactions with us, including, but not limited to, acting as our counterparties in connection with interest rate and currency derivative transactions. In the future, the

underwriters may, from time to time, perform similar services for us, for which they may receive customary fees and reimbursement of expenses, and may also engage in various financial transactions with us. In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve our securities and/or instruments.

        On December 30, 2011, we acquired a commercial loan portfolio with a face value of $333 million from affiliates of Citigroup Global Markets Inc., and we entered into a new $236 million financing facility with an affiliate of Wells Fargo Securities, LLC to finance the acquisition of this portfolio.

        In addition, in December 2011, we sold a $42.5 million A-note interest in a $62.5 million first mortgage loan that we had previously originated to an affiliate of Wells Fargo Securities, LLC. We have a right to cause this affiliate to purchase from us an additional interest in the first mortgage loan if certain conditions are satisfied.

        An affiliate of Wells Fargo Securities, LLC is the lender under our $108.9 million master repurchase and securities contract, dated as of March 31, 2010, our $550 million amended and restated master repurchase and securities contract, dated as of February 28, 2011, as amended, and our $100 million master repurchase and securities contract, dated as of March 18, 2011. As described above under "Summary—Recent Developments," on March 5, 2012, our subsidiary extended the maturity date of our $100 million master repurchase and securities contract with an affiliate of Wells Fargo Securities, LLC, from March 16, 2012 to March 15, 2013.

        Further, as described above under "Summary—Recent Developments," on March 26, 2012, we, through certain of our subsidiaries, entered into a new $125 million financing facility with an affiliate of Citigroup Global Markets Inc. to finance commercial mortgage loans and senior interests in commercial mortgage loans originated or acquired by us.

STARWOOD PROPERTY TRUST, INC.

        Starwood Property Trust, Inc. is a Maryland corporation that commenced operations on August 17, 2009, upon the completion of our initial public offering. We are focused primarily on originating, investing in, financing and managing commercial mortgage loans and other commercial real estate debt investments, commercial mortgage-backed securities ("CMBS"), and other commercial real estate-related debt investments. We will also invest in residential mortgage loans and residential mortgage-backed securities ("RMBS"). We collectively refer to commercial mortgage loans, other commercial real estate debt investments, CMBS, other commercial real estate-related debt investments, residential mortgage loans, and RMBS as our target assets.

        Our objective is to provide attractive risk adjusted returns to our investors over the long term, primarily through dividends and secondarily through capital appreciation. In order to achieve these objectives, we are focusing on asset selection and the relative value of various sectors within the debt market to construct a diversified investment portfolio designed to produce attractive returns across a variety of market conditions and economic cycles.

        We are externally managed and advised by SPT Management, LLC pursuant to the terms of a management agreement. SPT Management, LLC, is controlled by Barry Sternlicht, our Chairman and Chief Executive Officer. SPT Management, LLC is an affiliate of Starwood Capital Group, a privately-held private equity firm founded and controlled by Mr. Sternlicht. Since its inception in 1991, Starwood Capital Group (including Starwood Capital-named affiliates controlled by Mr. Sternlicht) has sponsored numerous opportunistic funds, including dedicated debt funds, dedicated hotel funds and several standalone and co-investment partnerships.

        We intend to elect to be taxed as a real estate investment trust ("REIT"), for U.S. federal income tax purposes, commencing with our taxable year ending December 31, 2009. We generally will not be subject to U.S. federal income taxes on our taxable income to the extent that we annually distribute all of our taxable income to stockholders and maintain our qualification as a REIT. We also operate our business in a manner that permits us to maintain our exemption from registration under the Investment Company Act of 1940, as amended.

        Our corporate headquarters office is located at 591 West Putnam Avenue, Greenwich, Connecticut, and our telephone number is (203) 422-8100.

CAUTIONARY STATEMENT REGARDING FORWARD LOOKING STATEMENTS

        This prospectus and the documents we incorporate herein by reference contain certain forward-looking statements, including without limitation, statements concerning our operations, economic performance and financial condition. These forward-looking statements are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are developed by combining currently available information with our beliefs and assumptions and are generally identified by the words "believe," "expect," "anticipate" and other similar expressions. Forward-looking statements do not guarantee future performance, which may be materially different

from that expressed in, or implied by, any such statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of their dates.

        These forward-looking statements are based largely on our current beliefs, assumptions and expectations of our future performance taking into account all information currently available to us. These beliefs, assumptions and expectations can change as a result of many possible events or factors, not all of which are known to us or within our control, and which could materially affect actual results, performance or achievements. Factors that may cause actual results to vary from our forward-looking statements include, but are not limited to:

•

factors described in our Annual Report on Form 10-K for the year ended December 31, 2009, including those set forth under the caption "Risk Factors";



•

defaults by borrowers in paying debt service on outstanding items;



•

impairment in the value of real estate property securing our loans;



•

availability of mortgage origination opportunities acceptable to us;



•

national and local economic and business conditions;



•

general and local commercial real estate property conditions;



•

changes in federal government policies;



•

changes in federal, state and local governmental laws and regulations;



•

increased competition from entities engaged in mortgage lending;



•

changes in interest rates; and



•

the availability of and costs associated with sources of liquidity and financing.

        In light of these risks and uncertainties, there can be no assurances that the results referred to in the forward-looking statements contained in this prospectus and the documents we incorporate herein by reference will in fact occur. Except to the extent required by applicable law or regulation, we undertake no obligation to, and expressly disclaim any such obligation to, update or revise any forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events, changes to future results over time or otherwise.

USE OF PROCEEDS

        Unless otherwise indicated in a prospectus supplement, we intend to use the net proceeds from the offering of securities under this prospectus for general corporate purposes, including funding our investment activity, repayment of indebtedness and working capital. Further details relating to the use of the net proceeds from the offering of securities under this prospectus will be set forth in the applicable prospectus supplement.

RATIO OF EARNINGS TO COMBINED FIXED CHARGES
AND PREFERRED STOCK DIVIDENDS

        The following table sets forth our ratios of earnings to combined fixed charges and preferred stock distributions for the periods shown:

DESCRIPTION OF CAPITAL STOCK

        The following is a summary of the material rights and preferences of our capital stock. While we believe that the following description covers the material terms of our capital stock, 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 capital stock. Copies of our charter and bylaws are filed as exhibits to the registration statement of which this prospectus is a part. See "Where You Can Find More Information."

General

        Our charter provides that we may issue up to 500,000,000 shares of common stock, $0.01 par value per share, and 100,000,000 shares of preferred stock, $0.01 par value per share. Our charter authorizes our 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 August 20, 2010, 47,587,800 shares of common stock were issued and outstanding and no shares of preferred stock were issued and outstanding.

        Under Maryland law, stockholders are not personally liable for the debts or obligations of a corporation solely as a result of their status as stockholders.

Shares of Common Stock

        Subject to the preferential rights of any other class or series of shares of stock and to the restrictions on ownership and transfer of shares of stock contained in our charter, holders of shares of common stock are entitled to receive dividends on such shares of common stock out of assets legally available therefor if, as and when authorized by our board of directors and declared by us, and the holders of our shares of 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 that we may offer will be issued by us and do not represent any interest in or obligation of Starwood Capital Group or any of its affiliates. 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 FDIC, any other governmental agency or any insurance company. The shares of common stock that we may offer will not benefit from any insurance guarantee association coverage or any similar protection.

---

        Subject to the provisions of our charter regarding the restrictions on ownership and transfer of shares of stock contained in our charter 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 the 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 or redemption rights, have no preemptive rights to subscribe for any securities of our company and generally have no appraisal rights. Subject to the provisions of our charter regarding the restrictions on ownership and transfer of shares of stock, shares of common stock will have equal dividend, liquidation and other rights.

        Under the Maryland General Corporation Law (the "MGCL"), a Maryland corporation generally cannot dissolve, amend its charter, merge with another entity 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 the removal of directors for cause and an amendment to our charter related to the removal of directors for cause) may be approved by a majority of all of the votes entitled to be cast on the matter. Our charter also provides that we may sell or transfer all or substantially all of our assets if approved by our board of directors and by the affirmative vote of a majority of all the votes entitled to be cast on the matter.

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 ownership and 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, 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 our shares of 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 provides 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, it 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 our shares of 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 Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), our shares of 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, not more than 50% of the value of the outstanding shares of stock may be owned, directly or indirectly, by five or fewer individuals (as defined in the Internal Revenue Code to include certain entities) during the last half of a taxable year (other than the first year for which an election to be a REIT has been made).

        Our charter contains restrictions on the ownership and transfer of our shares of common stock and other outstanding shares of stock. 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 Internal Revenue Code, more than 9.8% by value or number of shares, whichever is more restrictive, of our outstanding shares of common stock (the common stock 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). We refer to the common stock ownership limit and the aggregate share ownership limit collectively 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 our shares of 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 our shares of stock.

        The constructive ownership rules under the Internal Revenue 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. 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 9.8% by value or number of shares, whichever is more restrictive, of our outstanding capital stock (or the acquisition of an interest in an entity that owns, actually or constructively, our shares of 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, or 9.8% by value or number of shares, whichever is more restrictive, of our outstanding capital stock and thereby subject the shares of common stock or total shares of stock to the applicable ownership limits.

        Our board of directors may, in its sole discretion, exempt (prospectively or retroactively) a person from the above-referenced ownership limits. However, the board of directors may not exempt any person whose actual or constructive ownership of our outstanding stock would result in our being "closely held" within the meaning of Section 856(h) of the Internal Revenue 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, actually or constructively, an interest in one of our tenants (or a tenant of any entity which we own or control) that would cause us to own, actually or constructively, 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 it 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 to a trust of the shares of stock causing the violation. As a condition of its waiver, our board of directors may require an opinion of counsel or Internal Revenue Services (the "IRS") ruling satisfactory to our board of directors with respect to our qualification as a REIT.

6

---

        In connection with the waiver of the ownership limits or at any other time, our board of directors may from time to time increase or decrease the ownership limits for all other persons and entities; provided, however, that any decrease may be made only prospectively as to existing holders (other than a decrease as a result of a retroactive change in existing law, in which case the decrease will be effective immediately); and provided further that the ownership limits 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 limits, our board of directors may require such opinions of counsel, affidavits, undertakings or agreements as it may deem necessary or advisable in order to determine or ensure our qualification as a REIT. Reduced ownership limits will not apply to any person or entity whose percentage ownership in our shares of common stock or total shares of stock, as applicable, is in excess of such decreased ownership limits until such time as such person's or entity's percentage of our shares of common stock or total shares of stock, as applicable, equals or falls below the decreased ownership limits, but any further acquisition of our shares of common stock or total shares of stock, as applicable, in excess of such percentage ownership of our shares of common stock or total shares of stock will be in violation of the ownership limits.

        Our charter provisions further prohibit:

•

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



•

any person from transferring our shares of stock if such transfer would result in our shares of 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 our shares of stock that will or may violate any of the foregoing restrictions on transferability and ownership will be required to immediately give written notice to us, or, in the case of such proposed or attempted transaction, give 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 our shares of stock would result in our shares of 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 our shares of 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 Internal Revenue Code or otherwise failing to qualify as a REIT, then that number of shares (rounded up to the nearest whole share) that would cause us 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 violative 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 limits or our being "closely held" under Section 856(h) of the Internal Revenue Code or otherwise failing to qualify as a REIT, then our charter provides that the transfer of the shares will be void.

        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, in the case of a devise or gift, the last reported sales price reported on the NYSE (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, accepts 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. 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 for value (for example, in the case of a gift, devise or other transaction), the last reported sales price reported on the NYSE (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 trustee for the shares held in the trust. Any net sales proceeds in excess of the amount payable to the purported record transferee will be immediately paid to the 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 will 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 corporate action, then the trustee may not rescind and recast the vote.

        In addition, if our board of directors or other permitted designees determine in good faith that a transfer or other event would violate the restrictions on ownership and transfer of our shares of stock set forth in our charter, our board of directors or other permitted designees will take such action as it deems or they deem advisable to refuse to give effect to or to prevent such transfer or other event, 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 Internal Revenue 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 each class and series of our stock beneficially owned and a description of the manner in which such shares are held. Each such owner shall provide us with such additional information as we may request in order to determine the effect, if any, of such 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 and to ensure compliance with the ownership limits.

        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 interest of the stockholders.

Transfer Agent and Registrar

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

DESCRIPTION OF WARRANTS

        We may issue warrants to purchase shares of common stock. Warrants may be issued independently or together with any securities or may be attached to or separate from the securities. Each series of warrants will be issued under a separate warrant agreement to be entered into by us with a bank or trust company, as warrant agent, as specified in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

        We will describe the specific terms of any warrants we may offer in the prospectus supplement relating to those warrants, which terms will include:

•

the title of the warrants;



•

the aggregate number of warrants;



•

the price or prices at which the warrants will be issued;



•

the designation, amount and terms of the securities purchasable upon exercise of the warrants;



•

any provisions for adjustment of the number of securities purchasable upon exercise of the warrants or the exercise price of the warrants;



•

the designation and terms of the other securities, if any, with which the warrants are to be issued and the number of the warrants issued with each security;



•

if applicable, the date on and after which the warrants and the securities purchasable upon exercise of the warrants will be separately transferable;



•

the price or prices at which the securities purchasable upon exercise of the warrants may be purchased;



•

the minimum or maximum number of warrants which may be exercised at any one time;



•

the date on which the right to exercise the warrants shall commence and the date on which the right shall expire;



•

a discussion of any material U.S. federal income tax considerations applicable to the acquisition, ownership, exercise and disposition of the warrants;

9

---

•

information with respect to book-entry procedures, if applicable; and



•

any additional terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

        Each warrant will entitle the holder of the warrant to purchase for cash the number of shares of common stock at the exercise price stated or determinable in the applicable prospectus supplement. Warrants may be exercised at any time up to the close of business on the expiration date shown in the applicable prospectus supplement, unless otherwise specified in such prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be exercised as described in the applicable prospectus supplement. When the warrant holder makes the payment and properly completes and signs the warrant certificate at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will, as soon as possible, forward the shares of common stock that the warrant holder has purchased. If the warrant holder exercises the warrant for less than all of the warrants represented by the warrant certificate, we will issue a new warrant certificate for the remaining warrants.

CERTAIN PROVISIONS OF THE MARYLAND GENERAL CORPORATION LAW
AND OUR CHARTER AND BYLAWS

        The following description of the terms of our stock and of certain provisions of Maryland law is only a summary. For a complete description, we refer you to the MGCL, our charter and our bylaws. Copies of our charter and bylaws are filed as exhibits to the registration statement of which this prospectus is a part. See "Where You Can Find More Information."

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 more than 15. Our charter and bylaws currently provide that except as may be provided by the board of directors in setting the terms of any class or series of preferred stock, any vacancy on the board of directors for any reason other than an increase in the number of directors may be filled only by a majority of the remaining directors, even if the remaining directors do not constitute a quorum. Any vacancy in the number of directors created by an increase in the number of directors may be filled by a majority vote of the entire board of 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 charter, each of our directors is elected by our common stockholders to serve until the next annual meeting 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 subject to the rights of holders of one or more classes or series of preferred stock to elect or remove one or more directors, a director may be removed but only with cause and then only by the affirmative vote of at least two-thirds of the votes of common stockholders entitled to be cast generally in the election of directors. Cause means, with respect to any particular director, a conviction of a felony or a final judgment of a court of competent jurisdiction holding that such director caused demonstrable, material harm to us through bad faith or active and deliberate dishonesty. This provision, when coupled with the exclusive power of our board of directors to fill vacancies on our board of directors, precludes stockholders from (1) removing incumbent directors except upon a substantial affirmative vote and with cause 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 voting stock or an affiliate or associate of the corporation who, at any time within the two-year period 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 (1) 80% of the votes entitled to be cast by holders of outstanding voting shares of stock of the corporation and (2) two-thirds of the votes entitled to be cast by holders of voting shares of 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. A person is not an interested stockholder under the statute if the board of directors approved in advance the transaction by which the person otherwise would have become an interested stockholder. Our board of directors may provide that its approval is subject to compliance with any terms and conditions determined by it.

        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 between us and any person. Consequently, the five-year prohibition and the supermajority vote requirements will not apply to business combinations between us and any person described above. 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 our company with the supermajority vote requirements and other provisions of the statute.

        Should our board of directors opt back into the statute or otherwise fail to approve a business combination, 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.

11

---

        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 (1) shares acquired in a merger, consolidation or share exchange if the corporation is a party to the transaction or (2) 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 our shares of 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 Securities Exchange Act of 1934 (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 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.

        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, which removal will be allowed only for cause, (2) vest in the board the exclusive power to fix the number of directorships and (3) require, unless called by our chairman of the board, Chief Executive Officer or president or the board of directors, the written request of stockholders of not less than a majority of all 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 our 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

12

---

bylaws, a special meeting of our stockholders will also be called by our 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 (which must be declared advisable by our board of directors and approved by the affirmative vote of the holders of not less than two-thirds of all the votes entitled to be cast on the matter), and amendments increasing and decreasing the aggregate number of authorized shares of stock or the number of shares of stock of any class or series (which may be approved by our board of directors without stockholder approval), our charter may be amended only if the amendment is declared advisable by our board of directors and approved by the affirmative vote of the holders of not less than 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 Our Company

        The dissolution of our company must be declared advisable by a majority of our entire board of directors and approved by 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 our board of directors and the proposal of 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 is a stockholder of record both at the time of giving the notice required by our bylaws and at the time of the meeting, who is entitled to vote at the meeting and who 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) pursuant to our notice of the meeting, (2) by or at the direction of our board of directors or (3) provided that our board of directors has determined that directors will be elected at such meeting, by a stockholder who is a stockholder of record both at the time of giving the notice required by our bylaws and at the time of the meeting, who is entitled to vote at the meeting and who 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 our shares of common stock or otherwise be in the best interests of our stockholders, including business combination provisions, restrictions on ownership and transfer of our stock 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 in to 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 limiting 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

13

---

or 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 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 is made or threatened to be made a party by reason of his 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 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 fullest 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 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, REIT, partnership, joint venture, trust, employee benefit plan or any 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 personnel or agent of our company or a predecessor of our company.

14

---

        In addition, we may enter into indemnification agreements with each of our directors and executive officers that would provide for indemnification to the maximum extent permitted by Maryland law.

        Insofar as the foregoing provisions permit indemnification of directors, officers or persons controlling us for liability arising under the Securities Act of 1933 (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

General

        The following is a summary of the material United States federal income tax consequences of an investment in stock of Starwood Property Trust, Inc. In addition, the U.S. federal income tax consequences of the acquisition, ownership, disposition and exercise of the warrants will be described in the applicable prospectus supplement relating to the warrants. For purposes of this section under the caption "U.S. Federal Income Tax Considerations," references to "Starwood Property Trust, Inc.," "we," "our" and "us" mean only Starwood Property Trust, Inc. and not its subsidiaries or other lower-tier entities, except as otherwise indicated. This summary is based upon the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code"), the regulations promulgated by the U.S. Treasury Department, rulings and other administrative pronouncements issued by the Internal Revenue Service (the "IRS"), 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 consequences described below. We have not sought and will not seek an advance ruling from the IRS regarding any matter discussed herein. The summary is also based upon the assumption that we will operate Starwood Property Trust, Inc. and its subsidiaries and affiliated entities in accordance with their applicable organizational documents or partnership agreements. This summary is for general information only and is not tax advice. It does not purport to discuss all aspects of U.S. federal income taxation that may be important to a particular investor in light of its investment or tax circumstances, or to investors subject to special tax rules, such as:

•

financial institutions;



•

insurance companies;



•

broker-dealers;



•

regulated investment companies;



•

partnerships and trusts;



•

persons who hold our stock on behalf of other persons as nominees;



•

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



•

persons holding our stock as part of a "straddle," "hedge," "conversion transaction," "synthetic security" or other integrated investment; and



•

except to the extent discussed below, tax-exempt organizations and foreign investors.

        If a partnership, including for this purpose any entity that is treated as a partnership for U.S. federal income tax purposes, holds our shares of stock, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. An investor that is a partnership and the partners in such partnership should consult their tax advisors about the U.S. federal income tax consequences of the acquisition, ownership and disposition of our stock.

        This summary assumes that investors will hold their stock as a capital asset, which generally means as property held for investment.

        The federal income tax treatment of holders of our 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 tax consequences to any particular stockholder of holding our stock will depend on the stockholder's particular tax circumstances. For example, a stockholder that is a partnership or trust that has issued an equity interest to certain types of tax exempt organizations may be subject to a special entity-level tax if we make distributions attributable to "excess inclusion income." See "Taxation of Starwood Property Trust, Inc.—Taxable Mortgage Pools and Excess Inclusion Income" below. A similar tax may be payable by persons who hold our stock as nominees on behalf of tax exempt organizations. You are urged to consult your tax advisor regarding the federal, state, local, and foreign income and other tax consequences to you in light of your particular investment or tax circumstances of acquiring, holding, exchanging, or otherwise disposing of our stock.

Taxation of Starwood Property Trust, Inc.

        We intend to elect to be taxed as a real estate investment trust ("REIT"), commencing with our initial taxable year ending December 31, 2009, upon the filing of our federal income tax return for such year. We believe that we have been organized, and operated and expect to continue to operate in such a manner as to remain qualified for taxation as a REIT.

        In connection with the filing of this prospectus, we expect to receive an opinion of Sidley Austin LLP ("Tax Counsel") to the effect that we have been organized in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code, and that our proposed method of operation will enable us to meet the requirements for qualification and taxation as a REIT, commencing with our initial taxable year ending December 31, 2009. It must be emphasized that the opinion of Tax Counsel will be based on various assumptions relating to our organization and operation, and will be conditioned upon fact-based representations and covenants made by our management regarding our organization, assets, and income, and the past, present and future conduct of our business operations. While we 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, no assurance can be given by Tax Counsel or by us that we will qualify as a REIT for any particular year. The opinion will be expressed as of the date issued. Tax Counsel will have no obligation to advise us or our stockholders 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, 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 depends on our ability to meet on a continuing basis, through actual operating results, distribution levels, and diversity of stock and asset ownership, various qualification requirements imposed upon REITs by the Internal Revenue Code, the compliance with which will not be monitored or reviewed on a continuing basis by Tax Counsel. Our ability to qualify as a REIT also requires that we satisfy certain asset tests, some of which depend upon the fair market values of assets that we own directly or indirectly. Such values may not be susceptible to a precise

16

---

determination. Accordingly, no assurance can be given that the actual results of our operations for any taxable year will satisfy such requirements for qualification and taxation as a REIT.

Taxation of REITs in General

        As indicated above, our qualification and taxation as a REIT depends upon our ability to meet, on a continuing basis, various qualification requirements imposed upon REITs by the Internal Revenue Code. The material qualification requirements are summarized below under "—Requirements for Qualification—General." While we intend to operate so that we qualify as a REIT, no assurance can be given that the IRS will not challenge our qualification, or that we will be able to operate in accordance with the REIT requirements in the future. See "—Failure to Qualify."

        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 federal corporate income tax on our taxable income that is currently distributed to our stockholders. This treatment substantially eliminates the "double taxation" at the corporate and stockholder levels that generally results from investment in a corporation. In general, the income that we generate is taxed only at the stockholder level upon a distribution of dividends to our stockholders.

        For tax years through 2010, most domestic stockholders that are individuals, trusts or estates are taxed on corporate dividends at a maximum rate of 15% (the same as long-term capital gains). With limited exceptions, however, dividends from us or from other entities that are taxed as REITs are generally not eligible for this rate and will continue to be subject to tax at rates applicable to ordinary income, which will be as high as 35% through 2010 (and in the absence of legislative action, as high as 39.6% starting in 2011). See "Taxation of Stockholders—Taxation of Taxable Domestic Stockholders—Distributions."

        Any net operating losses, foreign tax credits and other tax attributes generally do not pass through to our stockholders, subject to special rules for certain items such as the capital gains that we recognize. See "Taxation of Stockholders."

        If we qualify as a REIT, we will nonetheless be subject to federal tax in the following circumstances:

•

We will be taxed at regular corporate rates on any undistributed REIT taxable income, including undistributed net capital gains.



•

We may be subject to the "alternative minimum tax" on our items of tax preference, including any deductions of net operating losses.



•

If we have net income from prohibited transactions, which are, in general, sales or other dispositions of inventory or 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. See "—Prohibited Transactions", and "—Foreclosure Property", below.



•

If we elect to treat property that we acquire in connection with a foreclosure of a mortgage loan or certain leasehold terminations as "foreclosure property", we may thereby avoid the 100% tax on gain from a resale of that property (if the sale would otherwise constitute a prohibited transaction), 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 derive "excess inclusion income" from an interest in certain mortgage loan securitization structures (that is, a "taxable mortgage pool" or a residual interest in a real estate mortgage investment conduit, or "REMIC"), we could be subject to corporate level federal income tax at a 35% rate to the extent that such income is allocable to specified types of tax-exempt

17

---

stockholders known as "disqualified organizations" that are not subject to unrelated business income tax. Similar rules will apply if we own an equity interest in a TMP through a subsidiary REIT of our operating partnership. To the extent that we own a REMIC residual interest or a TMP through a taxable REIT subsidiary ("TRS"), we will not be subject to this tax directly, but will indirectly bear such tax economically as the shareholder of such a TRS. See "—Taxable Mortgage Pools and Excess Inclusion Income" below.

•

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 we satisfy other requirements, we will be subject to a 100% tax on an amount based on the magnitude of the failure, as adjusted to reflect the profit margin associated with our gross income.



•

If we violate the asset tests (other than certain de minimis violations) or other requirements applicable to REITs, as described below, and yet maintain our qualification as a REIT because there is reasonable cause for the failure and other applicable requirements are met, we may be subject to a penalty tax. In that case, the amount of the penalty tax will be at least $50,000 per failure, and, in the case of certain asset test failures, will be determined as the amount of net income generated by the assets in question multiplied by the highest corporate tax rate (currently 35%) if that amount exceeds $50,000 per 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, we would be subject to a non-deductible 4% excise tax on the excess of the required distribution over the sum of (i) the amounts that we actually distributed, and (ii) the amounts we retained and upon which we paid income tax 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 a REIT's stockholders, as described below in "—Requirements for Qualification—General."



•

A 100% tax may be imposed on transactions between us and a TRS (as defined below) that do not reflect arm's length terms.



•

If we acquire appreciated assets from a corporation that is not a REIT (i.e., a corporation taxable under subchapter C of the Internal Revenue Code) 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 subchapter C corporation, we may 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 ten-year period following their acquisition from the subchapter C corporation.



•

The earnings of any subsidiaries that are subchapter C corporations, including any TRSs (as defined below), are subject to federal corporate income tax.

        In addition, we and our subsidiaries may be subject to a variety of taxes, including payroll taxes and state, local, and foreign income, property and other taxes on our assets and operations. We could also be subject to tax in situations and on transactions not presently contemplated.

Requirements for Qualification—General

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

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

18

---

        (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 Internal Revenue Code provisions applicable to REITs;

        (4)   that is neither a financial institution nor an insurance company subject to specific provisions of the Internal Revenue Code;

        (5)   the beneficial ownership of which is held by 100 or more persons;

        (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 Internal Revenue Code to include specified tax-exempt entities); and

        (7)   that meets other tests described below, including with respect to the nature of its income and assets.

        The Internal Revenue 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) need not be met during a corporation's initial tax year as a REIT (which, in our case, has been 2009). Our charter provides restrictions regarding the ownership and transfers of our stock, which are intended to assist us in satisfying the stock ownership requirements described in conditions (5) and (6) above.

        To monitor compliance with the stock ownership requirements, we generally are required to maintain records regarding the actual ownership of our stock. To do so, we must demand written statements each year from the record holders of significant percentages of our stock pursuant to which the record holders must disclose the actual owners of the stock (that is, the persons required to include our dividends in their gross income). We must maintain a list of those persons failing or refusing to comply with this demand as part of our records. We could be subject to monetary penalties if we fail to comply with these record keeping requirements. If you fail or refuse to comply with the demands, you will be required by Treasury regulations to submit a statement with your tax return disclosing the actual ownership of our stock and other information.

        In addition, a corporation generally may not elect to become a REIT unless its taxable year is the calendar year. We have adopted December 31 as our year end, and thereby satisfy this requirement.

        The Internal Revenue Code provides relief from violations of the REIT gross income requirements, as described below under "—Income Tests," in cases where a violation is due to reasonable cause and not to willful neglect, and other requirements are met, including the payment of a penalty tax that is based upon the magnitude of the violation. In addition, certain provisions of the Internal Revenue Code extend similar relief in the case of certain violations of the REIT asset requirements (see "—Asset Tests" below) and other REIT requirements, again provided that the violation is due to reasonable cause and not willful neglect, and other conditions are met, including the payment of a penalty tax. If we fail to satisfy any of the various REIT requirements, there can be no assurance that these relief provisions would be available to enable us to maintain our qualification as a REIT, and, if such relief provisions are available, the amount of any resultant penalty tax could be substantial.

Effect of Subsidiary Entities

        Ownership of Partnership Interests.    If we are a partner in an entity that is treated as a partnership for federal income tax purposes, Treasury regulations provide that we are deemed to own our proportionate share of the partnership's assets, and to earn our proportionate share of the partnership's

19

---

income, for purposes of the asset and gross income tests applicable to REITs. Our proportionate share of a partnership's assets and income is based on our capital interest in the partnership (except that for purposes of the 10% asset test, our proportionate share of the partnership's assets is based on our proportionate interest in the equity and certain debt securities issued by the partnership). In addition, the assets and gross income of the partnership are deemed to retain the same character in our hands. Thus, our proportionate share of the assets and items of income of any of our subsidiary partnerships will be treated as our assets and items of income for purposes of applying the REIT requirements.

        Disregarded Subsidiaries.    If we own a corporate subsidiary that is a "qualified REIT subsidiary," that subsidiary is generally disregarded for federal income tax purposes, and all of the subsidiary's assets, liabilities and items of income, deduction and credit are treated as our assets, liabilities and items of income, deduction and credit, including for purposes of the gross income and asset tests applicable to REITs. A qualified REIT subsidiary is any corporation, other than a TRS (as described below) that is wholly-owned by a REIT, or by other disregarded subsidiaries, or by a combination of the two. Other entities that are wholly-owned by us, including single member limited liability companies that have not elected to be taxed as corporations for federal income tax purposes, are also generally disregarded as separate entities for federal income tax purposes, including for purposes of the REIT income and asset tests. Disregarded subsidiaries, along with any partnerships in which we hold an equity interest, are sometimes referred to herein as "pass-through subsidiaries."

        In the event that a disregarded subsidiary of ours ceases to be wholly-owned—for example, if any equity interest in the subsidiary is acquired by a person other than us or another disregarded subsidiary of ours—or is classified as a TRS, the subsidiary's separate existence would no longer be disregarded for federal income tax purposes. Instead, the subsidiary 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 requirements applicable to REITs, including the requirement that REITs generally may not own, directly or indirectly, more than 10% of the securities of another corporation unless it is a TRS or a qualified REIT subsidiary. See "—Asset Tests" and "—Income Tests."

        Taxable Subsidiaries.    In general, we may jointly elect with a subsidiary corporation, whether or not wholly-owned, to treat such subsidiary corporation as a TRS. We generally may not own more than 10% of the securities of a taxable corporation, as measured by voting power or value, unless we and such corporation elect to treat such corporation as a TRS. The separate existence of a TRS or other taxable corporation is not ignored for federal income tax purposes. Accordingly, a TRS or other taxable corporation generally would be subject to corporate income tax on its earnings, which may reduce the cash flow that we and our subsidiaries generate in the aggregate, and may reduce our ability to make distributions to our stockholders.

        We are 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 a taxable subsidiary to us is an asset in our hands, and we treat the dividends paid to us from such taxable subsidiary, if any, as income. This treatment can affect our income and asset test calculations, as described below. Because we do not include the assets and income of TRSs or other taxable subsidiary corporations in determining our compliance with the REIT requirements, we may use such entities to undertake indirectly activities that the REIT rules might otherwise preclude us from doing directly or through pass-through subsidiaries. For example, we may use TRSs or other taxable subsidiary corporations to conduct activities that give rise to certain categories of income such as management fees or to conduct activities that, if conducted by us directly, could be treated in our hands as prohibited transactions.

        The TRS rules limit the deductibility of interest paid or accrued by a TRS to its parent REIT to assure that the TRS is subject to an appropriate level of corporate taxation. Accordingly, if we lend

20

---

money to a TRS, the TRS may be unable to deduct all or a part of the interest paid on that loan, and the lack of an interest deduction could result in a material increase in the amount of tax paid by the TRS. Further, the rules impose a 100% excise tax on transactions between a TRS and its parent REIT or the REIT's tenants that are not conducted on an arm's-length basis. We intend to scrutinize all of our transactions with our TRSs and to conduct such transactions on an arm's-length basis; however we cannot assure you that we will be successful in avoiding this excise tax.

        We may hold a significant amount of assets in one or more TRSs, subject to the limitation that securities in TRSs may not represent more than 25% of our assets. In general, we intend that loans that we originate or buy with an intention of selling in a manner that might expose us to a 100% tax on "prohibited transactions" will be originated or sold by a TRS. We anticipate that the TRS through which any such sales are made may be treated as a dealer for federal income tax purposes. As a dealer, the TRS may in general mark all the loans it holds on the last day of each taxable year to their market value, and may recognize ordinary income or loss on such loans with respect to such taxable year as if they had been sold for that value on that day. In addition, the TRS may further elect to be subject to the mark-to-market regime described above in the event that the TRS is properly classified as a "trader" as opposed to a "dealer" for U.S. federal income tax purposes.

Income Tests

        In order to qualify as a REIT, we must satisfy two gross income requirements on an annual basis. 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 hedging transactions, generally must be derived from investments relating to real property or mortgages on real property, including interest income derived from mortgage loans secured by real property (including certain types of mortgage-backed securities ("MBS")), "rents from real property," dividends received from other REITs, and gains from the sale of real estate assets, as well as specified income from temporary investments. Second, at least 95% of our gross income in each taxable year, excluding gross income from prohibited transactions and certain hedging transactions, must be derived from some combination of income that qualifies under the 75% gross 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. Income and gain from certain hedging transactions will be excluded from both the numerator and the denominator for purposes of both the 75% and 95% gross income tests. See "—Derivatives and Hedging Transactions."

        Interest income constitutes qualifying mortgage interest for purposes of the 75% gross income test (as described above) to the extent that the obligation upon which such interest is paid 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 or originated the mortgage loan, the interest income will be apportioned between the real property and the other collateral, 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.

        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 (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 held as inventory or dealer property. To the extent that we derive interest income from a mortgage loan, or income from the rental of real property where all

21

---

or a portion of the amount of interest or rental income 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 the borrower or lessee. This limitation does not apply, however, where the borrower or lessee leases substantially all of its interest in the property to tenants or subtenants, to the extent that the rental income derived by the borrower or lessee, as the case may be, would qualify as rents from real property had we earned the income directly.

        We intend to invest in commercial mortgage-backed securities ("CMBS"), residential mortgage-backed securities ("RMBS"), and agency securities that are either pass-through certificates or collateralized mortgage obligations as well as mortgage loans and mezzanine loans. We expect that the CMBS, RMBS, and agency securities will be treated either as interests in a grantor trust or as interests in a REMIC for federal income tax purposes and that all interest income from our CMBS, RMBS, and agency securities will be qualifying income for the 95% gross income test. In the case of MBS treated as interests in grantor trusts, we will be treated as owning an undivided beneficial ownership interest in the mortgage loans held by the grantor trust. The interest on such mortgage loans will be qualifying income for purposes of the 75% gross income test to the extent that such loans are secured by real property, as discussed above. In the case of CMBS, RMBS, or agency securities treated as interests in a REMIC, income derived from REMIC interests will generally be treated as qualifying income for purposes of the 75% and 95% gross income tests. If less than 95% of the assets of the REMIC are real estate assets, however, then only a proportionate part of our interest in the REMIC and income derived from the interest will qualify for purposes of the 75% gross income test. In addition, some REMIC regular interests are benefitted by interest swap or cap contracts or other derivative instruments that could produce some non-qualifying income for the holder of the REMIC regular interests. We expect that substantially all of our income from mortgage related securities will be qualifying income for purposes of the REIT gross income tests.

        We and our subsidiaries may invest in mezzanine loans, which are loans secured by equity interests in an entity that directly or indirectly owns real property, rather than by a direct mortgage of the real property. The IRS has issued Revenue Procedure 2003-65, which provides a safe harbor applicable to mezzanine loans. Under the Revenue Procedure, if a mezzanine loan meets each of the requirements contained in the Revenue Procedure, (1) the mezzanine loan will be treated by the IRS as a real estate asset for purposes of the asset tests described below, and (2) interest derived from the mezzanine loan will be treated as qualifying mortgage interest for purposes of the 75% income test. Although the Revenue Procedure provides a safe harbor on which taxpayers may rely, it does not prescribe rules of substantive tax law. We intend to structure any investments in mezzanine loans in a manner that complies with the various requirements applicable to our qualification as a REIT. To the extent that any of our mezzanine loans do not meet all of the requirements for reliance on the safe harbor set forth in the Revenue Procedure, however, there can be no assurance that the IRS will not challenge the tax treatment of these loans.

        See below under "—Asset Tests" for a discussion of the effect of our investment in CMBS or RMBS on our qualification as a REIT.

        We may hold certain participation interests, including B Notes, in mortgage loans and mezzanine loans. Such interests in an underlying loan are created by virtue of a participation or similar agreement to which the originator of the loan is a party, along with one or more participants. The borrower on the underlying loan is typically not a party to the participation agreement. The performance of this investment depends upon the performance of the underlying loan, and if the underlying borrower defaults, the participant typically has no recourse against the originator of the loan. The originator often retains a senior position in the underlying loan, and grants junior participations which absorb losses first in the event of a default by the borrower. We believe that our participation interests will qualify as real estate assets for purposes of the REIT asset tests described below, and that the interest

22

---

that we will derive from such investments will be treated as qualifying mortgage interest for purposes of the 75% income test. The appropriate treatment of participation interests for federal income tax purposes is not entirely certain, however, and no assurance can be given that the IRS will not challenge our treatment of our participation interests. In the event of a determination that such participation interests do not qualify as real estate assets, or that the income that we will derive from such participation interests does not qualify as mortgage interest for purposes of the REIT asset and income tests, we could be subject to a penalty tax, or could fail to qualify as a REIT. See "—Taxation of REITs in General," "—Requirements for Qualification—General," "—Asset Tests" and "—Failure to Qualify."

        We may invest in construction loans, the interest from which will be qualifying income for purposes of the REIT income tests, provided that the loan value of the real property securing the construction loan is equal to or greater than the highest outstanding principal amount of the construction loan during any taxable year, and other requirements are met. For purposes of construction loans, the loan value of the real property is the fair market value of the land plus the reasonably estimated cost of the improvements or developments (other than personal property) that will secure the loan and that are to be constructed from the proceeds of the loan.

        Rents received by us, if any, will qualify as "rents from real property" in satisfying the gross income requirements described above only if several conditions are met. If rent is partly attributable to personal property leased in connection with a lease of real property, the portion of the rent that is attributable to the personal property will not qualify as "rents from real property" unless it constitutes 15% or less of the total rent received under the lease. In addition, the amount of rent must not be based in whole or in part on the income or profits of any person. Amounts received as rent, however, generally will not be excluded from rents from real property solely by reason of being based on fixed percentages of gross receipts or sales. Moreover, for rents received to qualify as "rents from real property," we generally must not operate or manage the property or furnish or render services to the tenants of such property, other than through an "independent contractor" from which we derive no revenue. We are permitted, however, to perform services that are "usually or customarily rendered" in connection with the rental of space for occupancy only and which are not otherwise considered rendered to the occupant of the property. In addition, we may directly or indirectly provide non-customary services to tenants of our properties without disqualifying all of the rent from the property if the payments for such services do not exceed 1% of the total gross income from the property. For purposes of this test, we are deemed to have received income from such non-customary services in an amount at least 150% of the direct cost of providing the services. Moreover, we are generally permitted to provide services to tenants or others through a TRS without disqualifying the rental income received from tenants for purposes of the income tests. Also, rental income will qualify as rents from real property only to the extent that we do not directly or constructively hold a 10% or greater interest, as measured by vote or value, in the lessee's equity.

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

        Fees will generally be qualifying income for purposes of both the 75% and 95% gross income tests if they are received in consideration for entering into agreements to make loans secured by real property and the fees are not determined by income and profits. Other fees generally will not be qualifying income for purposes of either gross income test and will not be favorably counted for purposes of either gross income test. Any fees earned by a TRS will not be included for purposes of the gross income tests.

23

---

        Any income or gain that we or our pass-through subsidiaries derive from instruments that hedge certain risks, such as the risk of changes in interest rates, will be excluded from gross income for purposes of the 75% and 95% gross income tests, provided that specified requirements are met, including the requirement that the instrument is entered into during the ordinary course of our business, the instrument hedges risks associated with indebtedness issued by us or our pass-through subsidiary that is incurred to acquire or carry "real estate assets" (as described below under "—Asset Tests"), and the instrument is properly identified as a hedge along with the risk that it hedges within prescribed time periods. Income and gain from all other hedging transactions will not be qualifying income for either the 95% or 75% gross income test. See "—Derivatives and Hedging Transactions."

        Certain foreign currency gains are excluded from gross income for purposes of one or both of the gross income tests. "Real estate foreign exchange gain" will be excluded from gross income for purposes of the 75% gross income test. Real estate foreign exchange gain generally includes foreign currency gain attributable to any item of income or gain that is qualifying income for purposes of the 75% gross income test, foreign currency gain attributable to the acquisition or ownership of (or becoming or being the obligor under) obligations secured by mortgages on real property or on interest in real property and certain foreign currency gain attributable to certain "qualified business units" of a REIT. "Passive foreign exchange gain" will be excluded from gross income for purposes of the 95% gross income test. Passive foreign exchange gain generally includes real estate foreign exchange gain as described above, and also includes foreign currency gain attributable to any item of income or gain that is qualifying income for purposes of the 95% gross income test and foreign currency gain attributable to the acquisition or ownership of (or becoming or being the obligor under) obligations. Because passive foreign exchange gain includes real estate foreign exchange gain, real estate foreign exchange gain is excluded from gross income for purposes of both the 75% and 95% gross income test. These exclusions for real estate foreign exchange gain and passive foreign exchange gain do not apply to foreign currency gain derived from dealing, or engaging in substantial and regular trading, in securities. Such gain is treated as non-qualifying income for purposes of both the 75% and 95% 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 such year if we are entitled to relief under applicable provisions of the Internal Revenue Code. These relief provisions will be generally available if (1) our failure to meet these tests was due to reasonable cause and not due to willful neglect and (2) following our identification of the failure to meet the 75% or 95% gross income test for any taxable year, we file a schedule with the IRS setting forth each item of our gross income for purposes of the 75% or 95% gross income test for such taxable year in accordance with Treasury regulations yet to be issued. 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, we will not qualify as a REIT. As discussed above under "—Taxation of REITs in General," even where these relief provisions apply, the Internal Revenue Code imposes a tax based upon the amount by which we fail to satisfy the particular gross income test.

        Under The Housing and Economic Recovery Tax Act of 2008, the Secretary of the Treasury has been given broad authority to determine whether particular items of gain or income recognized after July 30, 2008, qualify or not under the 75% and 95% gross income tests, or are to be excluded from the measure of gross income for such purposes.

Timing Differences Between Receipt of Cash and Recognition of Income

        Due to the nature of the assets in which we will invest, we may be required to recognize taxable income from those assets in advance of our receipt of cash flow on or proceeds from disposition of

24

---

such assets, and may be required to report taxable income in early periods that exceeds the economic income ultimately realized on such assets.

        We may acquire debt instruments in the secondary market for less than their face amount. The discount at which such debt instruments are acquired may reflect doubts about their ultimate collectibility rather than current market interest rates. The amount of such discount will nevertheless generally be treated as "market discount" for U.S. federal income tax purposes. Accrued market discount is generally recognized as taxable income when and to the extent that any payment of principal is made on the debt instrument. Payments on residential mortgage loans are ordinarily made monthly, and consequently accrued market discount may have to be included in income each month as if the debt instrument were assured of ultimately being collected in full. If that turned out not to be the case, and we eventually collected less on the debt instrument than the amount we paid for it plus the market discount we had previously reported as income, there would be a bad debt deduction available to us at that time. Nevertheless, our (and our stockholders') ability to benefit from that bad debt deduction would depend on our having taxable income in that later taxable year. REITs may not carry back net operating losses, so this possible "income early, losses later" phenomenon could adversely affect us and our stockholders if it were persistent and in significant amounts.

        Some of the MBS that we acquire may have been issued with original issue discount. In general, we will be required to accrue original issue discount based on the constant yield to maturity of the MBS, and to treat it as taxable income in accordance with applicable U.S. federal income tax rules even though smaller or no cash payments are received on such debt instrument. As in the case of the market discount discussed in the preceding paragraph, the constant yield in question will be determined and we will be taxed based on the assumption that all future payments due on the MBS in question will be made, with consequences similar to those described in the previous paragraph if all payments on the MBS are not made.

        In addition, pursuant to our investment strategy, we may acquire distressed debt investments that are subsequently modified by agreement with the borrower. If the amendments to the outstanding debt are "significant modifications" under the applicable Treasury regulations, the modified debt may be considered to have been reissued to us in a debt-for-debt exchange with the borrower. In that event, we may be required to recognize taxable gain to the extent the principal amount of the modified debt exceeds our adjusted tax basis in the unmodified debt, even if the value of the debt or the payment expectations have not changed. Following such a taxable modification, we would hold the modified loan with a cost basis equal to its principal amount for U.S. federal tax purposes. To the extent that such modifications are made with respect to a debt instrument held by a TRS that is treated as a dealer or trader and that makes an election to use mark-to-market accounting, such TRS would be required at the end of each taxable year, including the taxable year in which any such modification were made, to mark the modified debt instrument to its fair market value as if the debt instrument were sold. In that case, the TRS could recognize a loss at the end of the taxable year in which the modifications were made to the extent that the fair market value of such debt instrument at such time was less than the instrument's tax basis.

        In addition, in the event that any debt instruments or MBS acquired by us are delinquent as to mandatory principal and interest payments, or in the event payments with respect to a particular debt instrument are not made when due, we may nonetheless be required to continue to recognize the unpaid interest as taxable income. Similarly, we may be required to accrue interest income with respect to subordinate MBS at the stated rate regardless of whether corresponding cash payments are received.

        Due to each of these potential timing differences between income recognition or expense deduction and 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

25

---

or take other action to satisfy the REIT distribution requirements for the taxable year in which this "phantom income" is recognized. See "—Annual Distribution Requirements."

Asset Tests

        At the close of each calendar quarter, we 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 some types of MBS and mortgage loans. Assets that do not qualify for purposes of the 75% asset test are subject to the additional asset tests described below.

        Second, the value of any one issuer's securities that we own may not exceed 5% of the value of our total assets. Third, we may not own more than 10% of any one issuer's outstanding securities, as measured by either voting power or value. The 5% and 10% asset tests do not apply to securities of TRSs and qualified REIT subsidiaries and the 10% asset test does not apply to "straight debt" having specified characteristics and to certain other securities described below. Solely for purposes of the 10% asset test, the determination of our interest in the assets of a partnership or limited liability company in which we own an interest will be based on our proportionate interest in any securities issued by the partnership or limited liability company, excluding for this purpose certain securities described in the Internal Revenue Code. Fourth, the aggregate value of all securities of TRSs that we hold may not exceed 25% of the value of our total assets.

        Notwithstanding the general rule, as noted above, that for purposes of the REIT income and asset tests, we are treated as owning our proportionate share of the underlying assets of a subsidiary partnership, if we hold indebtedness issued by a partnership, the indebtedness will be subject to, and may cause a violation of, the asset tests unless the indebtedness is a qualifying mortgage asset, or other conditions are met. Similarly, although stock of another REIT is a qualifying asset for purposes of the REIT asset tests, any non-mortgage debt that is issued by another REIT may not so qualify (such debt, however, will not be treated as a "security" for purposes of the 10% asset test, as explained below).

        Certain securities will not cause a violation of the 10% asset test (by value) described above. Such securities include instruments that constitute "straight debt," which includes, among other things, securities having certain contingency features. A security does not qualify as "straight debt" where a REIT (or a controlled TRS of the REIT) owns other securities of the same issuer which do not qualify as straight debt, unless the value of those other securities constitute, in the aggregate, 1% or less of the total value of that issuer's outstanding securities. In addition to straight debt, the Internal Revenue Code provides that certain other securities will not violate the 10% value test. Such securities include (a) any loan made to an individual or an estate, (b) certain rental agreements pursuant to which one or more payments are to be made in subsequent years (other than agreements between a REIT and certain persons related to the REIT under attribution rules), (c) any obligation to pay rents from real property, (d) securities issued by governmental entities that are not dependent in whole or in part on the profits of (or payments made by) a non-governmental entity, (e) any security (including debt securities) issued by another REIT, and (f) any debt instrument issued by a partnership if the partnership's income is of a nature that it would satisfy the 75% gross income test described above under "—Income Tests." In applying the 10% value test, a debt security issued by a partnership is not taken into account to the extent, if any, of the REIT's proportionate interest in the equity and certain debt securities issued by that partnership.

        We intend to invest in CMBS, RMBS, and agency securities that are either pass-through certificates or collateralized mortgage obligations as well as mortgage loans and mezzanine loans. We expect that the CMBS, RMBS, and agency securities will be treated either as interests in grantor trusts

26

---

or as interests in REMICs for federal income tax purposes. In the case of MBS treated as interests in grantor trusts, we would be treated as owning an undivided beneficial ownership interest in the mortgage loans held by the grantor trust. Such mortgage loans will generally qualify as real estate assets to the extent that they are secured by real property. We expect that substantially all of our MBS treated as interests in grantor trust will qualify as real estate assets.

        Any interests that we hold in a REMIC, including CMBS or RMBS that are structured as interests in REMICs, will generally qualify as real estate assets, and income derived from REMIC interests will generally be treated as qualifying income for purposes of the REIT income tests described above. If less than 95% of the assets of a REMIC are real estate assets, however, then only a proportionate part of our interest in the REMIC and income derived from the interest qualifies for purposes of the REIT asset and income tests. If we hold a "residual interest" in a REMIC or in a TMP, from which we derive "excess inclusion income," we will be required to either distribute the excess inclusion income or pay tax on it (or a combination of the two), even though we may not receive the income in cash. To the extent that distributed excess inclusion income is allocable to a particular stockholder, the income (1) would not be allowed to be offset by any net operating losses otherwise available to the stockholder, (2) would be subject to tax as unrelated business taxable income in the hands of most types of stockholders that are otherwise generally exempt from federal income tax, and (3) would result in the application of U.S. federal income tax withholding at the maximum rate (30%), without reduction pursuant to any otherwise applicable income tax treaty or other exemption to the extent allocable to foreign stockholders. Moreover, any excess inclusion income that we receive that is allocable to specified categories of tax-exempt investors which are not subject to unrelated business income tax, such as government entities, may be subject to corporate-level income tax in our hands, whether or not it is distributed. See "—Taxable Mortgage Pools and Excess Inclusion Income."

        To the extent that we hold mortgage participations or MBS that do not represent REMIC interests, such assets may not qualify as real estate assets, and the income generated from them might not qualify for purposes of either or both of the REIT income requirements, depending upon the circumstances and the specific structure of the investment.

        In addition, in certain cases, the modification of a debt instrument could result in the conversion of the instrument from a qualifying real estate asset to a wholly or partially non-qualifying asset that must be contributed to a TRS or disposed of in order for us to maintain our REIT status.

        In addition, certain of our mezzanine loans may qualify for the safe harbor in Revenue Procedure 2003-65 pursuant to which certain loans secured by a first priority security interest in ownership interests in a partnership or limited liability company will be treated as qualifying assets for purposes of the 75% real estate asset test and the 10% vote or value test. See "—Income Tests." We may make some mezzanine loans that do not qualify for that safe harbor and that do not qualify as "straight debt" securities or for one of the other exclusions from the definition of "securities" for purposes of the 10% asset test. We intend to try to make such investments in such a manner as not to fail the asset tests described above.

        We do not expect to obtain independent appraisals to support our conclusions as to the value of our total assets, or the value of any particular security or securities. Moreover, values of some assets, including instruments issued in securitization transactions, may not be susceptible to a precise determination, and values are subject to change in the future. Furthermore, the proper classification of an instrument as debt or equity for federal income tax purposes may be uncertain in some circumstances, which could affect the application of the REIT asset requirements. Accordingly, there can be no assurance that the IRS will not contend that our interests in our subsidiaries or in the securities of other issuers cause a violation of the REIT asset tests.

27

---

        Certain relief provisions are available to allow REITs to satisfy the asset requirements, or to maintain REIT qualification notwithstanding certain violations of the asset and other requirements. One such provision allows a REIT which fails one or more of the asset test requirements to nevertheless maintain its REIT qualification if (1) the REIT provides the IRS with a description of each asset causing the failure, (2) the failure is due to reasonable cause and not willful neglect, (3) the REIT pays a tax equal to the greater of (a) $50,000 per failure, and (b) the product of the net income generated by the assets that caused the failure multiplied by the highest applicable corporate tax rate (currently 35%), and (4) the REIT either disposes of the assets causing the failure within six months after the last day of the quarter in which it identifies the failure, or otherwise satisfies the relevant asset tests within that time frame. In the case of de minimis violations of the 10% and 5% asset tests, a REIT may maintain its qualification despite a violation of such requirements if (1) the value of the assets causing the violation does not exceed the lesser of 1% of the REIT's total assets, and $10,000,000, and (2) the REIT either disposes of the assets causing the failure within six months after the last day of the quarter in which it identifies the failure, or the relevant tests are otherwise satisfied within that time frame.

        If we fail to satisfy the asset tests at the end of a calendar quarter, such a failure would not cause us to lose our REIT qualification if we (1) satisfied the asset tests at the close of the preceding calendar quarter and (2) the discrepancy between the value of our assets and the asset requirements was not wholly or partly caused by an acquisition of non-qualifying assets, but instead arose from changes in the market value of our assets. If the condition described in (2) were not satisfied, we still could avoid disqualification by eliminating any discrepancy within 30 days after the close of the calendar quarter in which it arose or by making use of relief provisions described below.

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

        (1)   90% of our "REIT taxable income," computed without regard to our net capital gains and the deduction for dividends paid, and

        (2)   90% of our net income, if any, (after tax) from foreclosure property (as described below), minus

        (b)   the sum of specified items of noncash income.

        We generally must make these distributions in the taxable year to which they relate, or in the following taxable year if declared before we timely file our tax return for the year and if paid with or before the first regular dividend payment after such declaration. In order for distributions to be counted as satisfying the annual distribution requirements for REITs, and to provide us with a REIT-level tax deduction, the distributions must not be "preferential dividends." A dividend is not a preferential dividend if the distribution is (1) pro rata among all outstanding shares of stock within a particular class, and (2) in accordance with the preferences among different classes of stock as set forth in our 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. 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 for our stockholders to include their proportionate shares of such undistributed long-term capital gains in income, and to receive a corresponding credit for their share of the tax that we paid. Our stockholders would then increase their adjusted basis of their stock by the difference

28

---

between (a) the amounts of capital gain dividends that we designated and that they include in their taxable income, minus (b) the tax that we paid on their behalf with respect to that income.

        To the extent that in the future we may have available net operating losses carried forward from prior tax years, such losses may reduce the amount of distributions that we must make in order to comply with the REIT distribution requirements. Any distributions made with respect to such tax years into which net operating losses have been carried forward from prior tax years will nevertheless be taxable as dividends to the extent of current earnings and profits for such tax year. See "—Taxation of Stockholders—Taxation of Taxable Domestic Stockholders—Distributions."

        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 would be subject to a non-deductible 4% excise tax on the excess of such required distribution over the sum of (x) the amounts actually distributed, and (y) the amounts of income we retained and on which we paid corporate income tax.

        It is possible that, from time to time, we may not have sufficient cash to meet the distribution requirements due to timing differences between our actual receipt of cash, including receipt of distributions from our subsidiaries and our inclusion of items in income for federal income tax purposes. Alternatively, we may declare a taxable dividend payable in cash or stock at the election of each stockholder, where the aggregate amount of cash to be distributed in such dividend may be subject to limitation. In such case, for federal income tax purposes, the amount of the dividend paid in stock will be equal to the amount of cash that could have been received instead of stock. Other potential sources of non-cash taxable income include:

•

"residual interests" in REMICs or taxable mortgage pools;



•

loans or MBS held as assets that are issued at a discount and require the accrual of taxable economic interest in advance of receipt in cash; and



•

loans on which the borrower is permitted to defer cash payments of interest, and distressed loans on which we may be required to accrue taxable interest income even though the borrower is unable to make current servicing payments in cash.

        In the event that such timing differences occur, in order to meet the distribution requirements, it might be necessary for us to arrange for short-term, or possibly long-term, borrowings, or to pay dividends in the form of taxable in-kind distributions of property.

        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 REIT qualification or being taxed on amounts distributed as deficiency dividends. We will be required to pay interest and a penalty based on the amount of any deduction taken for deficiency dividends.

Prohibited Transactions

        Net income that 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, as discussed below) that is held primarily for sale to customers in the ordinary course of a trade or business by us, or by a borrower that has issued a shared appreciation mortgage or similar debt instrument to us. We intend to conduct our operations so that no asset that we own (or are treated as owning) will be treated as, or as having been, held for sale to customers, and that a sale of any such asset will not be treated as having been in the ordinary course of our business. Whether property is held "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 property that we sell will

29

---

not be treated as property held for sale to customers, or that we can comply with certain safe-harbor provisions of the Internal Revenue Code that would prevent such treatment. The 100% tax does 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 rates. We intend to try to structure our activities to avoid transactions that are prohibited transactions.

Foreclosure Property

        Foreclosure property is real property and any personal property incident to such real property (1) that we acquire as the result of having bid in the property at foreclosure, or having otherwise reduced the property to ownership or possession by agreement or process of law, after a default (or upon imminent default) on a lease of the property or a mortgage loan held by us and secured by the property, (2) for which we acquired the related loan or lease at a time when default was not imminent or anticipated, and (3) with respect to which we made a proper election to treat the property as foreclosure property. We generally will be 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 constitutes 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. To the extent that we receive any income from foreclosure property that does not qualify for purposes of the 75% gross income test, we intend to make an election to treat the related property as foreclosure property.

Foreign Investments

        We and our subsidiaries may hold investments in and pay taxes to foreign countries. Taxes that we pay in foreign jurisdictions may not be passed through to, or used by, our stockholders as a foreign tax credit or otherwise. Our foreign investments might also generate foreign currency gains and losses. Certain foreign currency gains recognized after July 30, 2008 would be excluded from gross income for purposes of one or both of the gross income tests, as discussed above. See above under "—Income Tests.

Derivatives and Hedging Transactions

        We and our subsidiaries may enter into hedging transactions with respect to interest rate exposure on one or more of our assets or liabilities. Any such hedging transactions could take a variety of forms, including the use of derivative instruments such as interest rate swap contracts, interest rate cap or floor contracts, futures or forward contracts, and options. Except to the extent provided by Treasury regulations, any income from a hedging 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, and (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 (or any asset that produces such income) 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 hedging 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 hedging transactions in a manner that does not jeopardize our qualification as a REIT. We may conduct some or all of our hedging activities through a TRS or other corporate entity, the income from which may be subject to federal income tax,

30

---

rather than by participating in the arrangements directly or through pass-through subsidiaries. No assurance can be given, however, that our hedging activities will not give rise to income that does not qualify for purposes of either or both of the REIT gross income tests, or that our hedging activities will not adversely affect our ability to satisfy the REIT qualification requirements.

Taxable Mortgage Pools and Excess Inclusion Income

        An entity, or a portion of an entity, may be classified as a taxable mortgage pool ("TMP") under the Internal Revenue Code if

•

substantially all of its assets consist of debt obligations or interests in debt obligations,



•

more than 50% of those debt obligations are real estate mortgages or interests in real estate mortgages as of specified testing dates,



•

the entity has issued debt obligations (liabilities) that have two or more maturities, and



•

the payments required to be made by the entity on its debt obligations (liabilities) "bear a relationship" to the payments to be received by the entity on the debt obligations that it holds as assets.

        Under regulations issued by the U.S. Treasury Department, if less than 80% of the assets of an entity (or a portion of an entity) consist of debt obligations, these debt obligations are considered not to comprise "substantially all" of its assets, and therefore the entity would not be treated as a TMP. Our financing and securitization arrangements may give rise to TMPs, with the consequences as described below.

        Where an entity, or a portion of an entity, is classified as a TMP, it is generally treated as a taxable corporation for federal income tax purposes. In the case of a REIT, or a portion of a REIT, or a disregarded subsidiary of a REIT, that is a TMP, however, special rules apply. The TMP is not treated as a corporation that is subject to corporate income tax, and the TMP classification does not directly affect the tax status of the REIT. Rather, the consequences of the TMP classification would, in general, except as described below, be limited to the stockholders of the REIT.

        A portion of the REIT's income from the TMP arrangement, which might be non-cash accrued income, could be treated as "excess inclusion income." Under recently issued IRS guidance, the REIT's excess inclusion income, including any excess inclusion income from a residual interest in a REMIC, must be allocated among its stockholders in proportion to dividends paid. The REIT is required to notify stockholders of the amount of "excess inclusion income" allocated to them. A stockholder's share of excess inclusion income:

•

cannot be offset by any net operating losses otherwise available to the stockholder,



•

is subject to tax as unrelated business taxable income in the hands of stockholders that are otherwise generally exempt from federal income tax, and



•

results in the application of U.S. federal income tax withholding at the maximum rate (30%), without reduction for any otherwise applicable income tax treaty or other exemption to the extent allocable to foreign stockholders.

        See "—Taxation of Stockholders." Under IRS guidance, to the extent that excess inclusion income is allocated to a tax-exempt stockholder of a REIT that is not subject to unrelated business income tax (such as a government entity), the REIT may be subject to tax on this income at the highest applicable corporate tax rate (currently 35%). In that case, the REIT could reduce distributions to such stockholders by the amount of such tax paid by the REIT attributable to such stockholder's ownership. Treasury regulations provide that such a reduction in distributions does not give rise to a preferential dividend that could adversely affect the REIT's compliance with its distribution requirements. See

31

---

"—Annual Distribution Requirements." The manner in which excess inclusion income is calculated, or would be allocated to stockholders, including allocations among shares of different classes of stock, is not clear under current law. As required by IRS guidance, we intend to make such determinations using a reasonable method. However, there can be no assurance that the IRS will not challenge our method of making any such determinations. If the IRS were to disagree with any such determinations made or with the method used by us, the amount of any excess inclusion income required to be taken into account by one or more stockholders could be significantly increased. Tax-exempt investors, foreign investors and taxpayers with net operating losses should carefully consider the tax consequences described above, and are urged to consult their tax advisors.

        If a subsidiary partnership of ours that we do not wholly-own, directly or through one or more disregarded entities, were a TMP, the foregoing rules would not apply. Rather, the partnership that is a TMP would be treated as a corporation for federal income tax purposes, and potentially would be subject to corporate income tax or withholding tax. In addition, this characterization would alter our income and asset test calculations, and could adversely affect our compliance with those requirements. We intend to monitor the structure of any TMPs in which we have an interest to ensure that they will not adversely affect our status as a REIT.

Failure to Qualify

        If we fail to satisfy one or more requirements for REIT qualification other than the income or asset tests, we could avoid disqualification if our failure is due to reasonable cause and not to willful neglect and we pay a penalty of $50,000 for each such failure. Relief provisions are available for failures of the income tests and asset tests, as described above in "—Income Tests" and "—Asset Tests."

        If we fail to qualify for taxation as a REIT in any taxable year, and the relief provisions described above do not apply, we would be subject to tax, including any applicable alternative minimum tax, on our taxable income at regular corporate rates. We cannot deduct distributions to stockholders in any year in which we are not a REIT, nor would we be required to make distributions in such a year. In this situation, to the extent of current and accumulated earnings and profits, distributions to domestic stockholders that are individuals, trusts and estates will generally be taxable at capital gains rates (through 2010). In addition, subject to the limitations of the Internal Revenue Code, corporate distributees may be eligible for the dividends received deduction. Unless we are entitled to relief under specific statutory provisions, we would also be disqualified from re-electing to be taxed as a REIT for the four taxable years following the year during which we lost qualification. It is not possible to state whether, in all circumstances, we would be entitled to this statutory relief.

Tax Aspects of Investments in Partnerships

General

        We may hold investments through entities that are classified as partnerships for federal income tax purposes. In general, partnerships are "pass-through" entities that are not subject to federal income tax. Rather, partners are allocated their proportionate shares of the items of income, gain, loss, deduction and credit of a partnership, and are potentially subject to tax on these items, without regard to whether the partners receive a distribution from the partnership. We will include in our income our proportionate share of these partnership items for purposes of the various REIT income tests and in computation of our REIT taxable income. Moreover, for purposes of the REIT asset tests, we will include in our calculations our proportionate share of any assets held by subsidiary partnerships. Our proportionate share of a partnership's assets and income is based on our capital interest in the partnership (except that for purposes of the 10% value test, our proportionate share is based on our

32

---

proportionate interest in the equity and certain debt securities issued by the partnership). See "Taxation of Starwood Property Trust, Inc.—Effect of Subsidiary Entities—Ownership of Partnership Interests."

Entity Classification

        Any investment in partnerships involves special tax considerations, including the possibility of a challenge by the IRS of the status of any subsidiary partnership as a partnership, as opposed to an association taxable as a corporation, for federal income tax purposes. If any of these entities were treated as an association for federal income tax purposes, it would be taxable as a corporation and therefore could be subject to an entity-level tax on its income. In such a situation, the character of our assets and items of gross income would change and could preclude us from satisfying the REIT asset tests or the gross income tests as discussed in "Taxation of Starwood Property Trust, Inc.—Asset Tests" and "—Income Tests," and in turn could prevent us from qualifying as a REIT, unless we are eligible for relief from the violation pursuant to relief provisions described above. See "Taxation of Starwood Property Trust, Inc.—Asset Tests," "—Income Test" and "—Failure to Qualify," above, for discussion of the effect of failure to satisfy the REIT tests for a taxable year, and of the relief provisions. In addition, any change in the status of any subsidiary partnership for tax purposes might be treated as a taxable event, in which case we could have taxable income that is subject to the REIT distribution requirements without receiving any cash.

Tax Allocations with Respect to Partnership Properties

        Under the Internal Revenue Code and the Treasury regulations, income, gain, loss and deduction attributable to appreciated or depreciated property that is contributed to a partnership in exchange for an interest in the partnership must be allocated for tax purposes so that the contributing partner is charged with, or benefits from, the unrealized gain or unrealized loss associated with the property at the time of the contribution. The amount of the unrealized gain or unrealized loss is generally equal to the difference between the fair market value of the contributed property at the time of contribution, and the adjusted tax basis of such property at the time of contribution (a "book-tax difference"). Such allocations are solely for federal income tax purposes and do not affect the book capital accounts or other economic or legal arrangements among the partners.

        To the extent that any of our subsidiary partnerships acquires appreciated (or depreciated) properties by way of capital contributions from its partners, allocations would need to be made in a manner consistent with these requirements. Where a partner contributes cash to a partnership at a time that the partnership holds appreciated (or depreciated) property, the Treasury regulations provide for a similar allocation of these items to the other (i.e., non-contributing) partners. These rules may apply to a contribution that we make to any subsidiary partnerships of the cash proceeds received in offerings of our stock. As a result, the partners of our subsidiary partnerships, including us, could be allocated greater or lesser amounts of depreciation and taxable income in respect of a partnership's properties than would be the case if all of the partnership's assets (including any contributed assets) had a tax basis equal to their fair market values at the time of any contributions to that partnership. This could cause us to recognize, over a period of time, taxable income in excess of cash flow from the partnership, which might adversely affect our ability to comply with the REIT distribution requirements discussed above.

Taxation of Stockholders

Taxation of Taxable Domestic Stockholders

        Distributions.    So long as we qualify as a REIT, the distributions that we make to our taxable domestic stockholders out of current or accumulated earnings and profits that we do not designate as capital gain dividends will generally be taken into account by stockholders as ordinary income and will

33

---

not be eligible for the dividends received deduction for corporations. With limited exceptions, our dividends are not eligible for taxation at the preferential income tax rates (i.e., the 15% maximum federal rate through 2010) for qualified dividends received by domestic stockholders that are individuals, trusts and estates from taxable C corporations. Such stockholders, however, are taxed at the preferential rates on dividends designated by and received from REITs to the extent that the dividends are attributable to

•

income retained by the REIT in the prior taxable year on which the REIT was subject to corporate level income tax (less the amount of tax),



•

dividends received by the REIT from TRSs or other taxable C corporations, or



•

income in the prior taxable year from the sales of "built-in gain" property acquired by the REIT from C corporations in carryover basis transactions (less the amount of corporate tax on such income).

        Distributions that we designate as capital gain dividends will generally be taxed to our stockholders as long-term capital gains, to the extent that such distributions do not exceed our actual net capital gain for the taxable year, without regard to the period for which the stockholder that receives such distribution has held its stock. The IRS requires a REIT that has two or more classes of shares outstanding to designate to each such class proportionate amounts of each type of its income, such as net capital gains, for each tax year based upon the percentage of total dividends distributed to each class for such year. We may elect to retain and pay taxes on some or all of our net long term capital gains, in which case provisions of the Internal Revenue Code will treat our stockholders as having received, solely for tax purposes, our undistributed capital gains, and the stockholders will receive a corresponding credit for taxes that we paid on such undistributed capital gains. See "Taxation of Starwood Property Trust, Inc.—Annual Distribution Requirements." Corporate 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 stockholders that are individuals, trusts and estates, and 35% in the case of stockholders that are corporations. Capital gains attributable to the sale of depreciable real property held for more than 12 months are subject to a 25% maximum federal income tax rate for taxpayers who are taxed as individuals, to the extent of previously claimed depreciation deductions.

        Distributions in excess of our current and accumulated earnings and profits will generally represent a return of capital and will not be taxable to a stockholder to the extent that the amount of such distributions does not exceed the adjusted basis of the stockholder's shares in respect of which the distributions were made. Rather, the distribution will reduce the adjusted basis of the stockholder's shares. To the extent that such distributions exceed the adjusted basis of a stockholder's shares, the stockholder generally must include such distributions 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 that we declare in October, November or December of any year and that is payable to a stockholder of record on a specified date in any such month will be treated as both paid by us and received by the stockholder on December 31 of such year, provided that we actually pay the dividend before the end of January of the following calendar year.

        Earnings and profits are allocated to distributions with respect to preferred stock before they are allocated to distributions with respect to common stock. Therefore, depending on our earnings and profits, distributions with respect to our preferred shares (as compared to distributions with respect to our common shares) are more likely to be treated as dividends than as a return of capital or a distribution in excess of basis. In addition, the IRS requires a REIT that has two or more classes of shares outstanding to designate to each such class proportionate amounts of each type of its income, such as net capital gains, for each tax year based upon the percentage of total dividends distributed to each class for such year.

34

---

        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 we must make in order to comply with the REIT distribution requirements. See "Taxation of Starwood Property Trust, Inc.—Annual Distribution Requirements." Such losses, however, are not passed through to stockholders and do not offset income of stockholders from other sources. In addition, any distributions made with respect to such tax years into which net operating losses have been carried forward from prior tax years will nevertheless be taxable as dividends to the extent that we have current earnings and profits.

        If excess inclusion income from a taxable mortgage pool or REMIC residual interest is allocated to any stockholder, that income will be taxable in the hands of the stockholder and would not be offset by any net operating losses of the stockholder that would otherwise be available. See "Taxation of Starwood Property Trust, Inc.—Taxable Mortgage Pools and Excess Inclusion Income." As required by IRS guidance, we intend to notify our stockholders if a portion of a dividend paid by us is attributable to excess inclusion income.

        Dispositions of Our Stock.    In general, capital gains recognized by individuals, trusts and estates upon the sale or disposition of our stock will be subject to a maximum federal income tax rate of 15% (through 2010) if the stock is held for more than one year, and will be taxed at ordinary income rates (of up to 35% through 2010) if the stock is held for one year or less. Gains recognized by stockholders that are corporations are subject to federal income tax at a maximum rate of 35%, whether or not such gains are classified as long-term capital gains. Capital losses recognized by a stockholder upon the disposition of our stock that was 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 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 stock by a 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 that we make that are required to be treated by the stockholder as long-term capital gain.

        If an investor recognizes a loss upon a subsequent disposition of our stock or other securities in an amount that exceeds a prescribed threshold, it is possible that the provisions of Treasury regulations involving "reportable transactions" could apply, with a resulting requirement to separately disclose the loss-generating transaction to the IRS. These regulations, though directed towards "tax shelters," are broadly written, and apply to transactions that would not typically be considered tax shelters. The Internal Revenue Code imposes significant penalties for failure to comply with these requirements. You should consult your tax advisors concerning any possible disclosure obligation with respect to the receipt or disposition of our stock or securities, or transactions that we might undertake directly or indirectly. Moreover, you should be aware that we and other participants in the transactions in which we are involved (including their advisors) might be subject to disclosure or other requirements pursuant to these regulations.

        Recently Enacted Legislation.    Recently enacted legislation will impose a 3.8% tax on the net investment income (which includes taxable dividends and gain recognized on a disposition of our stock) of certain individuals, trusts and estates, for taxable years beginning after December 31, 2012. You are encouraged to consult with your own tax advisor regarding the possible implications of this legislation on your investment in our stock.

        Information Reporting and Backup Withholding.    We will report to our stockholders and to the IRS the amount of distributions we pay during each calendar year and the amount of tax we withhold, if any. Under the backup withholding rules, you may be subject to backup withholding at a current rate of 28% (scheduled to increase to 31% in taxable years beginning in or after 2011) with respect to distributions unless you (a) are a corporation or come within certain other exempt categories and, when required, demonstrate this fact; or (b) provide a taxpayer identification number, certify as to no loss of

35

---

exemption from backup withholding, and otherwise comply with the applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. Any amount withheld under these rules will be refunded or credited against your federal income tax liability, provided that you timely furnish the IRS with certain required information.

Taxation of Foreign Stockholders

        The following is a summary of certain U.S. federal income and estate tax consequences of the ownership and disposition of our stock applicable to non-U.S. holders. A "non-U.S. holder" is any person other than:

•

a citizen or resident of the United States,



•

a corporation (or entity treated as a corporation for U.S. federal income tax purposes) created or organized in the United States or under the laws of the United States, or of any state thereof, or the District of Columbia,



•

an estate, the income of which is includable in gross income for U.S. federal income tax purposes regardless of its source, or



•

a trust if a United States court is able to exercise primary supervision over the administration of such trust and one or more United States fiduciaries have the authority to control all substantial decisions of the trust.

        If a partnership, including for this purpose any entity that is treated as a partnership for U.S. federal income tax purposes, holds our stock, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. An investor that is a partnership and the partners in such partnership should consult their tax advisors about the U.S. federal income tax consequences of the acquisition, ownership and disposition of our stock.

        The following discussion is based on current law, and is for general information only. It addresses only selected, and not all, aspects of U.S. federal income and estate taxation.

        In General.    For most foreign investors, investment in a REIT that invests principally in mortgage loans and MBS 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 Internal Revenue 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. holders that is (1) payable out of our earnings and profits, (2) not attributable to our capital gains and (3) not effectively connected with a U.S. trade or business of the non-U.S. holder, will be subject to U.S. withholding tax at the rate of 30%, unless reduced or eliminated by treaty. Reduced treaty rates and other exemptions are not available to the extent that income is attributable to excess inclusion income allocable to the foreign stockholder. Accordingly, we will withhold at a rate of 30% on any portion of a dividend that is paid to a non-U.S. holder and attributable to that holder's share of our excess inclusion income. See "Taxation of Starwood Property Trust, Inc.—Taxable Mortgage Pools and Excess Inclusion Income." As required by IRS guidance, we intend to notify our stockholders if a portion of a dividend paid by us is attributable to excess inclusion income.

36

---

        In general, non-U.S. holders 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. holder's investment in our stock is, or is treated as, effectively connected with the non-U.S. holder's conduct of a U.S. trade or business, the non-U.S. holder generally will be subject to U.S. federal income tax at graduated rates, in the same manner as domestic stockholders are taxed with respect to such dividends. Such income must generally be reported on a U.S. income tax return filed by or on behalf of the non-U.S. holder. The income may also be subject to the 30% branch profits tax in the case of a non-U.S. holder that is a corporation.

        Non-Dividend Distributions.    Unless our stock constitutes a U.S. real property interest (a "USRPI"), distributions that we make which are not dividends out of our earnings and profits will not be subject to U.S. income tax. If we cannot determine at the time 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. The non-U.S. holder may seek a refund from the IRS of any amounts withheld if it subsequently is determined that the distribution was, in fact, in excess of our current and accumulated earnings and profits. If our stock constitutes a USRPI, as described below, distributions that we make in excess of the sum of (a) the stockholder's proportionate share of our earnings and profits, and (b) the stockholder's basis in its stock, will be taxed under the Foreign Investment in Real Property Tax Act of 1980 ("FIRPTA") at the rate of tax, including any applicable capital gains rates, that would apply to a domestic 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 tax at a rate of 10% of the amount by which the distribution exceeds the stockholder's share of our earnings and profits.

        Capital Gain Dividends.    Under FIRPTA, a distribution that we make to a non-U.S. holder, to the extent attributable to gains from dispositions of USRPIs that we held directly or through pass-through subsidiaries, or USRPI capital gains, will, except as described below, be considered effectively connected with a U.S. trade or business of the non-U.S. holder and will be subject to U.S. income tax at the rates applicable to U.S. individuals or corporations, without regard to whether we designate the distribution as a capital gain dividend. See above under "—Taxation of Foreign Stockholders—Ordinary Dividends," for a discussion of the consequences of income that is effectively connected with a U.S. trade or business. In addition, we will be required to withhold tax equal to 35% of the maximum amount that could have been designated as USRPI capital gains dividends. Distributions subject to FIRPTA may also be subject to a 30% branch profits tax in the hands of a non-U.S. holder that is a corporation. A distribution is not a USRPI capital gain if we held an interest in the underlying asset solely as a creditor. Capital gain dividends received by a non-U.S. holder that are attributable to dispositions of our assets other than USRPIs are not subject to U.S. federal income or withholding tax, unless (1) the gain is effectively connected with the non-U.S. holder's U.S. trade or business, in which case the non-U.S. holder would be subject to the same treatment as U.S. holders with respect to such gain, or (2) the non-U.S. holder is a nonresident alien individual who was present in the United States for 183 days or more during the taxable year and has a "tax home" in the United States, in which case the non-U.S. holder will incur a 30% tax on his or her capital gains.

        A capital gain dividend that would otherwise have been treated as a USRPI capital gain will not be so treated or be subject to FIRPTA, and generally will not be treated as income that is effectively connected with a U.S. trade or business, and instead will be treated in the same manner as an ordinary dividend (see "—Taxation of Foreign Stockholders—Ordinary Dividends"), if (1) the capital gain dividend is received with respect to a class of stock that is regularly traded on an established securities market located in the United States, and (2) the recipient non-U.S. holder does not own more than 5% of that class of stock at any time during the year ending on the date on which the capital gain dividend is received. We believe that our common stock is "regularly traded" on an established securities

37

---

exchange. However, no assurance can be given that our common stock will continue to be, or that any other class of our stock will be, "regularly traded" on such a market.

        Dispositions of Our Stock.    Unless our stock constitutes a USRPI, a sale of our stock by a non-U.S. holder generally will not be subject to U.S. taxation under FIRPTA. Our 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 United States, excluding, for this purpose, interests in real property solely in a capacity as a creditor. We do not currently believe that our stock constitutes a USRPI. However, we cannot assure you that our stock will not become a USRPI.

        Even if the foregoing 50% test is not met, our stock nonetheless will not constitute a USRPI if we are a "domestically-controlled qualified investment entity." A domestically-controlled qualified investment entity includes a REIT, less than 50% of value of which is held directly or indirectly by non-U.S. holders at all times during a specified testing period. We believe that we are, and will be, a domestically-controlled qualified investment entity, and that a sale of our stock should not be subject to taxation under FIRPTA. However, no assurance can be given that we are or will remain a domestically-controlled qualified investment entity.

        In the event that we are not a domestically-controlled qualified investment entity, but our stock is "regularly traded," as defined by applicable Treasury regulations, on an established securities market, a non-U.S. holder's sale of our stock nonetheless would not be subject to tax under FIRPTA as a sale of a USRPI, provided that the selling non-U.S. holder held 5% or less of our stock (as determined under applicable Treasury regulations) at all times during the five-year period ending on the date of the sale. We believe that our common stock is regularly traded on an established securities market. However, no assurance can be given that our common stock will continue to be, or that any other class of our stock will be, regularly traded on such a market.

        If gain on the sale of our stock were subject to taxation under FIRPTA, the non-U.S. holder would be required to file a U.S. federal income tax return and 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 stock that would not otherwise be subject to FIRPTA will nonetheless be taxable in the United States to a non-U.S. holder in two cases: (1) if the non-U.S. holder's investment in our stock is effectively connected with a U.S. trade or business conducted by such non-U.S. holder, the non-U.S. holder will be subject to the same treatment as a U.S. stockholder with respect to such gain, or (2) if the non-U.S. holder is a nonresident alien individual who was present in the United States for 183 days or more during the taxable year and has a "tax home" in the United States, the nonresident alien individual will be subject to a 30% tax on the individual's capital gain. In addition, even if we are a domestically controlled qualified investment entity, upon disposition of our stock (subject to the 5% exception applicable to "regularly traded" stock described above), a non-U.S. holder may be treated as having gain from the sale or exchange of a USRPI if the non-U.S. holder (1) disposes of our stock within a 30-day period preceding the ex-dividend date of a distribution, any portion of which, but for the disposition, would have been treated as gain from the sale or exchange of a USRPI and (2) acquires, or enters into a contract or option to acquire, other shares of our stock within 30 days after such ex-dividend date.

        Estate Tax.    If our stock is owned or treated as owned by an individual who is not a citizen or resident (as specially defined for U.S. federal estate tax purposes) of the United States at the time of such individual's death, the stock will be includable in the individual's gross estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise, and may therefore be subject to U.S. federal estate tax.

38

---

        Information Reporting and Backup Withholding.    Generally, information reporting will apply to payments of distributions on, and of the proceeds from the disposition of, our stock, and backup withholding described above for a domestic stockholder will apply, unless the payee certifies that it is not a U.S. person or otherwise establishes an exemption. Backup withholding is not an additional tax. Any amount withheld under these rules will be refunded or credited against your federal income tax liability, provided that you timely furnish the IRS with certain required information.

        Recently Enacted Legislation.    Recently enacted legislation will impose a 30% withholding tax on dividends and gross proceeds of a disposition of our stock paid after December 31, 2012, to (i) foreign financial institutions (as defined in Section 1471(d)(4) of the Internal Revenue Code) unless they agree to collect and disclose to the IRS information regarding their direct and indirect United States account holders and (ii) certain other foreign entities unless they certify certain information regarding their direct and indirect United States owners. Under some circumstances, a foreign stockholder may be eligible for refunds or credits of such taxes.

Taxation of Tax-Exempt Stockholders

        Tax-exempt entities, including qualified employee pension and profit sharing trusts and individual retirement accounts, generally are exempt from federal income taxation. Such entities, however, may be subject to taxation on their unrelated business taxable income ("UBTI"). While some investments in real estate may generate UBTI, the IRS has ruled that dividend distributions from a REIT to a tax-exempt entity generally do not constitute UBTI. Based on that ruling, and provided that (1) a tax-exempt stockholder has not held our stock as "debt financed property" within the meaning of the Internal Revenue Code (i.e., where the acquisition or holding of the property is financed through a borrowing by the tax-exempt stockholder), and (2) our stock is not otherwise used in an unrelated trade or business, distributions that we make and income from the sale of our stock generally should not give rise to UBTI to a tax-exempt stockholder.

        To the extent that we are (or a part of us, or a disregarded subsidiary of ours is) a TMP, or if we hold residual interests in a REMIC, a portion of the dividends paid to a tax-exempt stockholder that is allocable to excess inclusion income may be treated as UBTI. If, however, excess inclusion income is allocable to some categories of tax-exempt stockholders that are not subject to UBTI, we might be subject to corporate level tax on such income, and, in that case, may reduce the amount of distributions to those stockholders whose ownership gave rise to the tax. See "Taxation of Starwood Property Trust, Inc.—Taxable Mortgage Pools and Excess Inclusion Income." As required by IRS guidance, we intend to notify our stockholders if a portion of a dividend paid by us is attributable to excess inclusion income.

        Tax-exempt stockholders that are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, and qualified group legal services plans exempt from federal income taxation under sections 501(c)(7), (c)(9), (c)(17) and (c)(20) of the Internal Revenue Code are subject to different UBTI rules, which generally require such stockholders to characterize distributions that we make as UBTI.

        In certain circumstances, a pension trust that owns more than 10% of our stock could be required to treat a percentage of the dividends as UBTI, if we are a "pension-held REIT." We will not be a pension-held REIT unless (1) we are required to "look through" one or more of our pension trust stockholders in order to satisfy the REIT closely held test and (2) either (i) one pension trust owns more than 25% of the value of our stock, or (ii) one or more pension trusts, each individually holding more than 10% of the value of our stock, collectively owns more than 50% of the value of our stock. Certain restrictions on ownership and transfer of our stock generally should prevent a tax-exempt entity from owning more than 10% of the value of our stock, and generally should prevent us from becoming a pension-held REIT.

39

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

Other Tax Considerations

Legislative or Other Actions Affecting REITs

        The present federal income tax treatment of REITs may be modified, possibly with retroactive effect, by legislative, judicial or administrative action at any time. The REIT rules are constantly under review by persons involved in the legislative process and by the IRS and the U.S. Treasury Department which may result in statutory changes as well as revisions to regulations and interpretations. Changes to the federal tax laws and interpretations thereof could adversely affect an investment in our stock.

Sunset of Reduced Tax Rate Provisions

        Several of the tax considerations described herein are subject to a sunset provision. The sunset provisions generally provide that for taxable years beginning after December 31, 2010, certain provisions that are currently in the Internal Revenue Code will revert back to a prior version of those provisions. These provisions include provisions related to the reduced maximum income tax rate for long-term capital gains of 15% (rather than 20%) for taxpayers taxed at individual rates, the application of the 15% tax rate to qualified dividend income, the reduced maximum income tax rate for ordinary income of 35% (rather than 39.6%) for taxpayers taxed at individual rates and certain other tax rate provisions described herein. Stockholders are urged to consult their own tax advisors regarding the effect of sunset provisions in their particular circumstances.

State, Local and Foreign Taxes

        We and our subsidiaries and 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. We may own properties located in numerous jurisdictions, and may be required to file tax returns in some or all of those jurisdictions. Our state, local or foreign tax treatment and that of our stockholders may not conform to the federal income tax treatment discussed above. We may pay foreign property taxes, and dispositions of foreign property or operations involving, or investments in, foreign property may give rise to foreign income or other tax liability in amounts that could be substantial. Any foreign taxes that we incur do not pass through to stockholders as a credit against their U.S. federal income tax liability. Prospective investors 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 stock.

PLAN OF DISTRIBUTION

        We may sell the securities offered by this prospectus from time to time in one or more transactions, including without limitation:

•

through underwriters or dealers;



•

directly to purchasers;



•

in a rights offering;



•

in "at the market" offerings, within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market on an exchange or otherwise;



•

through agents; or



•

through a combination of any of these methods.

40

---

The prospectus supplement with respect to any offering of securities will include the following information:

•

the terms of the offering;



•

the names of any underwriters or agents;



•

the name or names of any managing underwriter or underwriters;



•

the purchase price or initial public offering price of the securities;



•

the net proceeds from the sale of the securities;



•

any delayed delivery arrangements;



•

any underwriting discounts, commissions and other items constituting underwriters' compensation;



•

any discounts or concessions allowed or reallowed or paid to dealers;



•

any commissions paid to agents; and



•

any securities exchange on which the securities may be listed.

Sale through Underwriters or Dealers

        If underwriters are used in the sale, the underwriters will acquire the securities for their own account. The underwriters may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. Underwriters may offer securities to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. Unless we inform you otherwise in the applicable prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all of the offered securities if they purchase any of them. The underwriters may change from time to time any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers.

        If we offer securities in a subscription rights offering to our existing stockholders we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting agreement, we may retain a dealer-manager to manage a subscription rights offering for us.

        During and after an offering through underwriters, the underwriters may purchase and sell the securities in the open market. These transactions may include overallotment and stabilizing transactions and purchases to cover syndicate short positions created in connection with the offering. The underwriters may also impose a penalty bid, which means that selling concessions allowed to syndicate members or other broker-dealers for the offered securities sold for their account may be reclaimed by the syndicate if the offered securities are repurchased by the syndicate in stabilizing or covering transactions. These activities may stabilize, maintain or otherwise affect the market price of the offered securities, which may be higher than the price that might otherwise prevail in the open market. If commenced, the underwriters may discontinue these activities at any time.

        Some or all of the securities that we offer though this prospectus may be new issues of securities with no established trading market. Any underwriters to whom we sell our securities for public offering and sale may make a market in those securities, but they will not be obligated to do so and they may discontinue any market making at any time without notice. Accordingly, we cannot assure you of the liquidity of, or continued trading markets for, any securities that we offer.

        If dealers are used in the sale of securities, we will sell the securities to them as principals. They may then resell those securities to the public at fixed prices or at varying prices determined by the dealers at the time of resale. We will include in the applicable prospectus supplement the names of the dealers and the terms of the transaction.

Direct Sales and Sales through Agents

        We may sell the securities directly. In this case, no underwriters or agents would be involved. We may also sell the securities through agents designated by us from time to time. In the applicable prospectus supplement, we will name any agent involved in the offer or sale of the offered securities, and we will describe any commissions payable to the agent. Unless we inform you otherwise in the applicable prospectus supplement, any agent will agree to use its reasonable best efforts to solicit purchases for the period of its appointment.

        We may sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities. We will describe the terms of any sales of these securities in the applicable prospectus supplement.

At-the-Market Offerings

        We may also sell the securities offered by any applicable prospectus supplement in "at the market offerings" within the meaning of Rule 415(a)(4) of the Securities Act, to or through a market maker or into an existing trading market, on an exchange or otherwise.

Remarketing Arrangements

        Securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreements, if any, with us and its compensation will be described in the applicable prospectus supplement.

Delayed Delivery Contracts

        If we so indicate in the applicable prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers from certain types of institutions to purchase securities from us at the public offering price under delayed delivery contracts. These contracts would provide for payment and delivery on a specified date in the future. The contracts would be subject only to those conditions described in the applicable prospectus supplement. The applicable prospectus supplement will describe the commission payable for solicitation of those contracts.

General Information

        We may have agreements with the underwriters, dealers, agents and remarketing firms to indemnify them against certain civil liabilities, including liabilities under the Securities Act, or to contribute with respect to payments that the underwriters, dealers, agents or remarketing firms may be required to make. Underwriters, dealers, agents and remarketing firms may be customers of, engage in transactions with or perform services for us in the ordinary course of their businesses.

        In compliance with Financial Regulatory Authority ("FINRA") guidelines, the maximum commission or discount to be received by any FINRA member or independent broker dealer may not exceed 8% of the aggregate amount of the securities offered pursuant to this prospectus or any applicable prospectus supplement.

In addition, the description of U.S. federal income tax consequences contained in the section entitled "U.S. Federal Income Tax Considerations" is based on the opinion of Sidley Austin LLP. If the validity of any securities is also passed upon by counsel for the underwriters, dealers or agents of an offering of those securities, that counsel will be named in the applicable prospectus supplement.
