This preliminary prospectus supplement and the accompanying prospectus are not an offer to sell these securities and we are not soliciting offers to buy these securities in any jurisdiction where the offer or sale is not permitted.

Starwood Property Trust, Inc. is offering $400,000,000 aggregate principal amount of its % Convertible Senior Notes due 2019, or the notes, under this prospectus supplement. The notes will bear interest at a rate equal to % per year, payable semiannually in arrears on January 15 and July 15 of each year, beginning on January 15, 2014. The notes will mature on January 15, 2019.

Holders may convert their notes at their option prior to the close of business on the business day immediately preceding July 15, 2018 but only under the following circumstances: (1) during any fiscal quarter commencing after September 30, 2013 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; (2) during the five consecutive business day period after any five consecutive trading day period, or the measurement period, in which the trading price (as defined herein) per $1,000 principal amount of notes for each trading day of such measurement period was less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate on each such trading day; or (3) upon the occurrence of specified corporate events. On or after July 15, 2018 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances. Upon conversion of a note, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, as described in this prospectus supplement.

The conversion rate will initially equal shares of common stock per $1,000 principal amount of notes (equivalent to a conversion price of approximately $ per share of common stock). The conversion rate will be subject to adjustment upon the occurrence of certain events, but will not be adjusted for any accrued and unpaid interest. In addition, following the occurrence of a make-whole fundamental change, we will, in certain circumstances, increase the conversion rate for a holder that converts its notes in connection with such make-whole fundamental change.

We may not redeem the notes prior to maturity. No sinking fund will be provided for the notes.

If we undergo a fundamental change, holders may require us to purchase the notes in whole or in part for cash at a fundamental change purchase price equal to 100% of the principal amount of the notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date.

The notes will be our senior unsecured obligations and will rank senior in right of payment to any future indebtedness that is expressly subordinated in right of payment to the notes, equal in right of payment to our existing and future unsecured indebtedness that is not so subordinated, effectively junior to any future secured indebtedness to the extent of the value of the assets securing such indebtedness and structurally junior to all existing and future indebtedness (including trade payables) and preferred equity of our subsidiaries, other than to the extent the notes are guaranteed in the future by our subsidiaries, as described in this prospectus supplement.

We do not intend to apply for listing of the notes on any securities exchange. Our common stock, par value $0.01 per share, is listed on the New York Stock Exchange under the trading symbol "STWD." The last reported sale price of our common stock on the New York Stock Exchange on June 26, 2013 was $23.54 per share.

Investing in the notes involves certain risks.

SUMMARY

This summary highlights information about us and the notes being offered by this prospectus supplement and the accompanying prospectus. This summary is not complete and may not contain all of the information that you should consider prior to investing in the notes and our common stock. For a more complete understanding of our company, we encourage you to read this entire document, including the information incorporated by reference into this document.

Overview

We are a Maryland corporation that commenced operations in August 2009, upon the completion of our initial public offering. We are focused on originating, acquiring, financing and managing commercial mortgage real estate loans and other commercial real estate debt investments, commercial mortgage-backed securities, or CMBS, and other commercial real estate-related debt investments. We collectively refer to commercial real estate mortgage loans, CMBS, other commercial real estate-related debt investments, residential mortgage-backed securities, residential real estate owned, or residential REO, and distressed and non-performing residential mortgage loans as our target assets. As market conditions change over time, we may adjust our strategy to take advantage of changes in interest rates and credit spreads as well as economic and credit conditions.

Our objective is to provide attractive risk-adjusted returns to our investors over the long term, primarily through dividends and secondarily through capital appreciation. We employ leverage, to the extent available, to fund the acquisition of our assets and to increase potential returns to our stockholders. In order to achieve these objectives, we are focusing on asset selection and the relative value of various sectors within the real estate debt market to construct a diversified investment portfolio designed to produce attractive returns across a variety of market conditions and economic cycles. We are organized as a holding company that conducts its business primarily through its various wholly owned subsidiaries.

We are externally managed and advised by SPT Management, LLC, or our manager, pursuant to the terms of a management agreement. Our manager is controlled by Barry Sternlicht, our Chairman and Chief Executive Officer. Our manager is an affiliate of Starwood Capital Group Global, L.P., or Starwood Capital Group, a privately-held private equity firm founded and controlled by Mr. Sternlicht.

We have elected to be taxed as a real estate investment trust, or REIT, for U.S. federal income tax purposes, commencing with our initial taxable year ended December 31, 2009. 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, or the Investment Company Act.

Our corporate headquarters office is located at 591 West Putnam Avenue, Greenwich, Connecticut 06830, and our telephone number is (203) 422-7700.

Recent Developments

Completion of Acquisition of LNR

On April 19, 2013, we completed the acquisition of certain business segments of LNR, a real estate investment, finance, management and development company, from a group of investors for a cash purchase price of approximately $862 million. To finance a portion of the LNR acquisition, we entered into a $300.0 million senior secured term loan agreement. The term loan has an initial maturity date of April 17, 2020. We expect to incur transaction

expenses of approximately $13 million, severance expenses of approximately $6.3 million and the acceleration of approximately $2 million of change-in-control bonus expense (that was originally scheduled to accrue over the nine month period subsequent to the closing of the transaction) relating to LNR during the quarter ending June 30, 2013. These merger-related expense estimates are preliminary and there can be no assurance that the actual merger-related expenses that we incur will not differ materially from our current expectations.

Potential Separation Transaction

During 2012, our board of directors approved the expansion of our investment guidelines to include investments in (i) residential REO that are primarily comprised of single-family rental homes and (ii) distressed and non-performing residential mortgage loans (acquired with the expectation of their conversion into residential REO or other commercial resolution), and we began to opportunistically purchase portfolios of single-family rental homes and distressed and non-performing residential mortgage loans. As of March 31, 2013, our portfolio of residential REO properties consisted of 1,690 single-family rental homes located in seven states with an aggregate investment, inclusive of acquisition and actual and budgeted upfront renovation costs, of approximately $229.3 million. In addition, as of the same date we had acquired distressed and non-performing residential mortgage loans with an unpaid principal balance of approximately $357.8 million and a total purchase price of approximately $169.8 million.

There can be no assurance as to the timing, terms, structure or completion of such a spin-off. For a discussion of risks associated with a potential spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans, see "Risk Factors—Risks Related to a Potential Separation Transaction."

The Offering

The following summary is provided solely for your convenience and is not intended to be complete. You should read the full text and more specific details contained elsewhere in this prospectus supplement and the accompanying prospectus. For purposes of this "offering summary," references to "Starwood Property Trust, Inc.," "we," "our" and "us" refer only to Starwood Property Trust, Inc. and not its subsidiaries. For a more detailed description of the notes, see "Description of the Notes" in this prospectus supplement and "Description of Debt Securities" in the accompanying prospectus.


Issuer		Starwood Property Trust, Inc., a Maryland corporation
Securities Offered		$400,000,000 principal amount of % Convertible Senior Notes due 2019 (plus up to an additional $60,000,000 principal amount if the underwriters exercise their option to purchase additional notes to cover over-allotments, if any).
Maturity		January 15, 2019 unless earlier repurchased by us or converted.
Issue Price		%
Interest		% per year. Interest will accrue from the date of issuance (which is scheduled for July , 2013) or from the most recent date to which interest has been paid or duly provided for, and will be payable semiannually in arrears on January 15 and July 15 of each year, beginning on January 15, 2014. We will also be required to pay additional interest on the notes under the circumstances described under "Description of the Notes—Events of Default."
Conversion Rights		Holders may convert their notes at their option prior to the close of business on the business day immediately preceding July 15, 2018, but only under the following circumstances:
		• during any fiscal quarter commencing after September 30, 2013 (and only during such fiscal quarter), if the last reported sale price of our common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day;
		• during the five consecutive business day period after any five consecutive trading day period, or the measurement period, in which the trading price (as defined herein) per $1,000 principal amount of notes for each trading day of such measurement period was less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate on each such trading day; or


		• upon the occurrence of specified corporate events described under "Description of the Notes—Conversion Rights—Conversion Upon Specified Corporate Events."
		On or after July 15, 2018, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their notes at any time, regardless of the foregoing circumstances.
		The conversion rate will initially equal shares of common stock per $1,000 principal amount of notes (equivalent to an initial conversion price of approximately $ per share of common stock), subject to adjustment as described in this prospectus supplement.
		In addition, following the occurrence of certain corporate events, we will, in certain circumstances, increase the conversion rate for a holder that converts its notes in connection with such corporate event. See "Description of the Notes—Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change."
		You will not receive any additional cash payment representing accrued and unpaid interest, if any, upon conversion of a note, except in limited circumstances. Instead, interest will be deemed paid by our payment or delivery, as the case may be, of the cash, shares of our common stock or combination of cash and shares of our common stock into which your note is convertible. See "Description of the Notes—Conversion Rights—General."
Settlement Upon Conversion		Upon conversion, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination thereof at our election. We refer to our obligation to pay or deliver these amounts as our conversion obligation. If we satisfy our conversion obligation solely in cash or through payment and delivery, as the case may be, of a combination of cash and shares of our common stock (rather than solely through delivery of shares of our common stock), the amount of cash and shares of our common stock, if any, due upon conversion will be based on a daily conversion value (as described herein) calculated on a proportionate basis for each trading day in the 40 trading-day cash settlement averaging period (as described herein). See "Description of the Notes—Conversion Rights—Settlement Upon Conversion."


No Redemption		We may not redeem the notes prior to maturity, and no sinking fund will be provided for the notes.
Fundamental Change		If we undergo a "fundamental change" (as defined under "Description of the Notes—Fundamental Change Permits Holders to Require Us to Purchase Notes"), subject to certain conditions, you may require us to purchase for cash all or part of your notes. The fundamental change purchase price will equal 100% of the principal amount of the notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date.
Ranking		The notes will be our senior unsecured obligations and will rank:
		• senior in right of payment to any future indebtedness we may have that is expressly subordinated in right of payment to the notes;
		• equal in right of payment to our existing and future unsecured indebtedness that is not so subordinated, including our 4.55% convertible senior notes due 2018;
		• effectively junior in right of payment to any of our existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness; and
		• structurally subordinated to all existing and future indebtedness (including trade payables) and preferred equity of our subsidiaries as well as to any of our existing or future indebtedness that may be guaranteed by any of our subsidiaries (to the extent of any such guarantee) unless and to the extent such subsidiaries in the future guarantee the notes in the manner described below under "—Future Subsidiary Guarantees."
		As of March 31, 2013, our total consolidated indebtedness pro forma for our acquisition of LNR (excluding trade payables and unfunded commitments) was $2.1 billion, $458.4 million of which was secured indebtedness of ours to which the notes would have ranked effectively junior and $1.0 billion of which was indebtedness of our subsidiaries to third parties (excluding trade payables) to which the notes would have been structurally subordinated.
		The indenture governing the notes will not limit the amount of debt that we or our subsidiaries may incur.
Future Subsidiary Guarantees		The indenture will provide that we will cause each subsidiary of ours that guarantees payment by us of any unsecured debt securities of ours issued by us in an offering registered pursuant to the Securities Act of 1933, as amended, or the Securities Act, or in an offering exempt from such registration pursuant to Rule 144A and/or Regulation S thereunder to execute and deliver to the trustee a supplemental indenture pursuant to which such subsidiary will guarantee payment of the notes on terms substantially similar to the guarantee of such debt securities. The indenture will further provide that we may remove any such guarantee by any such subsidiary if such subsidiary no longer provides a guarantee with respect to any such debt securities.


Events of Default		Except as described under "Description of the Notes—Events of Default," if an event of default with respect to the notes occurs, holders may, upon satisfaction of certain conditions, accelerate the principal amount of the notes plus accrued and unpaid interest. In addition, the principal amount of the notes plus accrued and unpaid interest will automatically become due and payable in the case of certain types of bankruptcy or insolvency events of default involving us.
Ownership Limit		Subject to certain exceptions, our charter restricts ownership of more than 9.8% by value or number of shares, whichever is more restrictive, of our outstanding shares of common stock, or of our outstanding capital stock, in order to protect our status as a REIT for U.S. federal income tax purposes. Notwithstanding any other provision of the notes, no holder of notes will be entitled to receive our common stock following conversion of such notes to the extent that receipt of such common stock would cause such holder (after application of certain constructive ownership rules) to exceed the ownership limit contained in our charter.
		If any delivery of shares of our common stock owed to a holder upon conversion of notes is not made, in whole or in part, as a result of the limitations described above, our obligation to make such delivery shall not be extinguished and we shall deliver such shares as promptly as practicable after any such converting holder gives notice to us that such delivery would not result in it being the beneficial or constructive owner of more than 9.8% (by value or number, whichever is more restrictive) of the shares of common stock, or of our outstanding capital stock, outstanding at such time.
Book-Entry Form		The notes will be issued in book-entry form and will be represented by one or more permanent global certificates deposited with, or on behalf of, The Depository Trust Company, which we refer to as DTC, and registered in the name of a nominee of DTC. Beneficial interests in any of the notes will be shown on, and transfers will be effected only through, records maintained by DTC or its nominee and any such interest may not be exchanged for certificated securities, except in limited circumstances.


Absence of a Public Market for the Notes		Prior to this offering, there was no public market for the notes, and we do not intend to list the notes on any national securities exchange. If no active trading market develops, you may not be able to resell your notes at their fair market value or at all. Future trading prices of the notes will depend on many factors, including the market price of our common stock, prevailing interest rates, our operating results and the market for similar securities. We have been informed by the representatives of the underwriters that certain underwriters currently intend to make a market in the notes after this offering is completed. However, such underwriters are not obligated to do so, and they may cease their market-making at any time and without notice.
No Listing		We do not intend to apply for listing of the notes on any securities exchange. Our common stock is listed on the New York Stock Exchange under the symbol "STWD."
Material U.S. Federal Income Tax Consequences		For certain material U.S. federal income tax considerations relating to the purchase, ownership and disposition of the notes and the shares of our common stock into which the notes are convertible, see "Supplemental U.S. Federal Income Tax Considerations" in this prospectus supplement and "U.S. Federal Income Tax Considerations" in the accompanying prospectus.
Trustee, Paying Agent and Conversion Agent		The Bank of New York Mellon.
Use of Proceeds		We estimate that the net proceeds from this offering will be approximately $ million (or approximately $ million if the underwriters exercise their option to purchase additional notes to cover over-allotments, if any, in full), after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We intend to use the net proceeds from this offering to originate and purchase additional commercial mortgage loans and other target assets and investments. 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. See "Use of Proceeds."
Governing Law		New York.


Risk Factors		An investment in the notes involves risks, and prospective investors should carefully consider the matters discussed under "Risk Factors" beginning on page S-9 of this prospectus supplement and the reports we file with the SEC pursuant to the Securities Exchange Act of 1934, as amended, or the Exchange Act, incorporated by reference into this prospectus supplement and the accompanying prospectus, before making a decision to invest in the notes.
		If a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans as described under "—Recent Developments" occurs, our stockholders as of the applicable record date will receive a distribution in the form of the spin-off entity's shares of common stock. There can be no assurance as to the timing, terms, structure or completion of any such transaction. However, if a spin-off occurs, the notes may become convertible as described under "Description of the Notes—Conversion Rights—Conversion Upon Specified Corporate Events" and the conversion rate for the notes may be subject to adjustment as described under "Description of the Notes—Conversion Rights—Conversion Rate Adjustments." If the conversion rate for the notes is adjusted as a result of a spin-off, the conversion rate adjustment will result in a deemed distribution (of an amount equal to the fair market value on the date of such deemed distribution of the additional number of shares into which a holder's notes are convertible) taxable as a dividend to the extent of the allocable earnings and profits, if any, and treated as a return of capital (and a reduction in a holder's tax basis) to the extent the fair market value exceeds the allocable share of earnings and profits.

Investing in the notes and our common stock involves risks. You should carefully read and consider the risks described below as well as the risks described in the sections entitled "Item 1. Business" and "Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2012, and in our other periodic reports filed with the SEC, and incorporated by reference into this prospectus supplement and the accompanying prospectus, including the risks described in our Annual Report on Form 10-K for the year ended December 31, 2012 under the sub-section entitled "Risks Related to LNR's Business and the Company's Pending Acquisition of LNR" and in our Current Report on Form 8-K filed on February 11, 2013 under the section entitled "Risk Factors Relating to LNR's Business and the Company's Pending Acquisition of LNR." You should also carefully read and consider 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 the notes. 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.

We expect that the trading price of the notes will be significantly affected by changes in the market price of our common stock, the interest rate environment and our credit quality, each of which could change substantially at any time.

We expect that the trading price of the notes will depend on a variety of factors, including, without limitation, the market price of our common stock, the interest rate environment and our credit quality. Each of these factors may be volatile, and may or may not be within our control.

For example, the trading price of the notes will increase with the market price and volatility of our common stock. We cannot, however, predict whether the market price of our common stock will rise or fall or whether the volatility of our common stock will continue at its historical level. In addition, general market conditions, including the level of, and fluctuations in, the market price of stocks generally, may affect the market price and the volatility of our common stock. Moreover, we may or may not choose to take actions that could influence the volatility of our common stock.

Likewise, if interest rates, or expected future interest rates, rise during the term of the notes, the yield of the notes will likely decrease, but the value of the convertibility option embedded in the notes will likely increase. Because interest rates and interest rate expectations are influenced by a wide variety of factors, many of which are beyond our control, we cannot assure you that changes in interest rates or interest rate expectations will not adversely affect the trading price of the notes.

Furthermore, the trading price of the notes will likely be significantly affected by any change in our credit quality. Because our credit quality is influenced by a variety of factors, some of which are beyond our control, we cannot guarantee that we will maintain or improve our credit quality during the term of the notes. In addition, because we may choose to take actions that adversely affect our credit quality, such as incurring additional debt, there can be no guarantee that our credit quality will not decline during the term of the notes, which would likely negatively impact the trading price of the notes.

The claims of holders of the notes will be structurally subordinated to claims of creditors of our subsidiaries because our subsidiaries will not guarantee the notes unless such subsidiaries guarantee certain of our other indebtedness. In addition, we are a holding company with minimal independent operations. Our ability to repay our debt, including the notes, depends on the performance of our subsidiaries and their ability to make distributions to us.

The notes will not be guaranteed by any of our subsidiaries unless and to the extent such subsidiaries in the future guarantee the notes in the manner described under "Description of the Notes—General—Future Subsidiary Guarantees." Accordingly, none of our subsidiaries is currently, and may not become, obligated to pay any amounts due pursuant to the notes, or to make any funds available therefor. Consequently, to the extent the notes do not have the benefit of subsidiary guarantees, claims of holders of the notes will be structurally subordinated to the claims of creditors and preferred stockholders of these subsidiaries, including trade creditors. As a result, in the event of a bankruptcy, liquidation or reorganization of any of our subsidiaries, such subsidiaries will pay the holders of their debt and their trade creditors before they will be able to distribute any of their assets to us.

As a holding company, substantially all of our business is conducted through our subsidiaries, which are separate and distinct legal entities. Therefore, our ability to service our indebtedness, including the notes, is dependent on the earnings and the distribution of funds (whether by dividend, distribution or loan) from our subsidiaries. None of our subsidiaries is obligated to make funds available to us for payment on the notes. We cannot assure you that the agreements governing the existing and future indebtedness of our subsidiaries will permit our subsidiaries to provide us with sufficient dividends, distributions or loans to fund payments on the notes when due. In addition, any payment of dividends, distributions or loans to us by our subsidiaries could be subject to restrictions on dividends or repatriation of earnings under applicable local law and monetary transfer restrictions in the jurisdictions in which our subsidiaries operate. Furthermore, Starwood Property Trust, Inc. guarantees many of the obligations of its subsidiaries and such guarantees may require us to provide substantial funds or assets to our subsidiaries, or their creditors at a time when Starwood Property Trust, Inc. needs liquidity to fund its own obligations, such as the notes.

As of March 31, 2013, pro forma for our acquisition of LNR, the notes would have been structurally subordinated to $1.0 billion of indebtedness and other liabilities of our subsidiaries to third parties (excluding trade payables).

Our substantial indebtedness could adversely affect our business, financial condition or results of operations and prevent us from fulfilling our obligations under the notes.

We currently have and, after this offering, will continue to have a significant amount of indebtedness. As of March 31, 2013, our total consolidated indebtedness pro forma for our acquisition of LNR was $2.1 billion (excluding trade payables and unfunded commitments). This substantial level of indebtedness increases the risk that we may be unable to generate enough cash to pay amounts due in respect of our indebtedness, including the notes.

Our substantial indebtedness could have important consequences to you and significant effects on our business. For example, it could:

In addition, the agreements that govern our current indebtedness contain, and the agreements that may govern any future indebtedness that we may incur may contain, financial and other restrictive covenants that will limit our ability to engage in activities that may be in our long-term best interests. Our failure to comply with those covenants could result in an event of default that, if not cured or waived, could result in the acceleration of all of our debt.

Despite our substantial current indebtedness, we and our subsidiaries may still be able to incur substantially more indebtedness. This could further exacerbate the risks associated with our substantial leverage.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future, including pursuant to a capital markets transaction such as a notes offering as well as secured indebtedness that will be structurally senior to the notes. Furthermore, neither the base indenture nor the supplemental indenture establishing the terms of the notes limits the amount of debt that we or our subsidiaries may issue. Adding new indebtedness to current debt levels could make it more difficult for us to satisfy our obligations with respect to the notes.

The risks associated with our substantial leverage may be exacerbated if we elect to spin-off our single-family rental homes and distressed and non-performing residential mortgage loans.

As part of our continuing efforts to provide value to our stockholders, we are actively evaluating a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans. Following any such spin-off, we will no longer receive earnings from our single-family rental homes and distressed and non-performing residential mortgage loans, which could make it more difficult to service our indebtedness.

The notes are not protected by restrictive covenants, which in turn may allow us to engage in a variety of transactions that may impair our ability to fulfill our obligations under the notes.

The indenture governing the notes will not contain any financial covenants and will not restrict us from paying dividends, incurring debt or issuing or repurchasing our other securities. Because the indenture will not contain any covenants or other provisions designed to afford holders of the notes protection in the event of a highly leveraged transaction involving us or in the event of a decline in our credit rating for any reason, including as a result of a takeover, recapitalization, highly leveraged transaction or similar restructuring involving us, except to the extent described under "Description of the Notes—Fundamental Change Permits Holders to Require Us to Purchase Notes," "Description of the Notes—Consolidation, Merger and Sale of Assets" and "Description of the Notes—Adjustment to

Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change," we may engage in transactions that may impair our ability to fulfill our obligations under the notes. Other than the repurchase right, the restrictions provided by the merger covenant and our obligation to increase the conversion rate with respect to the notes in certain circumstances upon the occurrence of certain events, we generally have no duty to consider the interests of holders of the notes in determining whether to engage in such transactions.

Recent regulatory actions may adversely affect the trading price and liquidity of the notes.

We expect that many investors in, and potential purchasers of, the notes will employ, or seek to employ, a convertible arbitrage strategy with respect to the notes. Investors would typically implement this strategy by selling short the common stock underlying the notes and dynamically adjusting their short position while they hold the notes. Investors may also implement this strategy by entering into swaps on our common stock in lieu of or in addition to short selling the common stock.

The SEC and other regulatory and self-regulatory authorities have implemented various rules and may adopt additional rules in the future that may impact those engaging in short selling activity involving equity securities (including our common stock), including Rule 201 of SEC Regulation SHO, the Financial Industry Regulatory Authority, Inc.'s "Limit Up-Limit Down" program, market-wide circuit breaker systems that halt trading of securities for certain periods following specific market declines, and rules stemming from the enactment and implementation of the Dodd-Frank Wall Street Reform and Consumer Protection Act. Past regulatory actions, including emergency actions or regulations have had a significant impact on the trading prices and liquidity of equity-linked instruments. Any governmental action that similarly restricts the ability of investors in, or potential purchasers of, the notes to effect short sales of our common stock or enter into swaps on our common stock could similarly adversely affect the trading price and the liquidity of the notes.

In addition, if investors and potential purchasers seeking to employ a convertible arbitrage strategy are unable to borrow or enter into swaps on our common stock, in each case on commercially reasonable terms, the trading price and liquidity of the notes may be adversely effected.

Some significant restructuring transactions that may adversely affect you may not constitute a "fundamental change" under the indenture, in which case we would not be obligated to offer to repurchase the notes.

Upon the occurrence of a "fundamental change" (as defined under "Description of the Notes—Fundamental Change Permits Holders to Require Us to Purchase Notes"), you have the right, at your option, to require us to repurchase your notes for cash. However, the definition of fundamental change contained in the indenture is limited to certain enumerated transactions. As a result, the fundamental change provision of the indenture will not afford protection to holders of notes in the event of other transactions that could adversely affect the notes. For example, transactions such as leveraged recapitalizations, refinancings, restructurings or acquisitions initiated by us may not constitute a fundamental change requiring us to repurchase the notes. In the event of any such transaction, holders of the notes would not have the right to require us to repurchase their notes, even though each of these transactions could increase the amount of our indebtedness, or otherwise adversely affect our capital structure or any credit ratings, thereby adversely affecting the holders of notes.

The adjustment to the conversion rate for notes converted in connection with a make-whole fundamental change may not adequately compensate you for any lost option value of your notes as a result of such transaction. In addition, the definition of a make-whole fundamental change is limited and may not protect you from losing some of the option value of your notes in the event of a variety of transactions that do not constitute a make-whole fundamental change.

Upon the occurrence of a make-whole fundamental change, we will, in certain circumstances, increase the conversion rate for a holder that converts its notes in connection with such make-whole fundamental change. The increase in the conversion rate will be determined based on the date on which the make-whole fundamental change becomes effective and the price paid (or deemed paid) per share of our common stock in such make-whole fundamental change, all as described below under "Description of the Notes—Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change."

Although the adjustment to the conversion rate for notes converted in connection with a make-whole fundamental change is designed to compensate you for the option value of your notes that you lose as a result of a make-whole fundamental change, it is only an estimate of such value and may not adequately compensate you for such lost option value. In addition, if the price paid (or deemed paid) for our common stock in the make-whole fundamental change is greater than $ per share or less than $ per share (in each case, subject to adjustment in accordance with the indenture), then we will not be required to adjust the conversion rate if you convert your notes in connection with such make-whole fundamental change. Moreover, in no event will we increase the conversion rate solely because of such an adjustment to a rate that exceeds shar es of common stock per $1,000 principal amount of notes, subject to adjustments in accordance with the indenture.

Furthermore, the definition of make-whole fundamental change contained in the indenture is limited to certain enumerated transactions. As a result, the make-whole fundamental change provisions of the indenture will not afford protection to holders of the notes in the event that other transactions occur that could adversely affect the option value of the notes. For example, transactions, such as leveraged recapitalizations, refinancings, restructurings or acquisitions, could significantly affect the trading characteristics of our common stock and thereby reduce the option value embedded in the notes without triggering a make-whole fundamental change.

In addition, our obligation to increase the conversion rate upon the occurrence of a make-whole fundamental change could be considered a penalty, in which case the enforceability thereof could be subject to general equity principles such as the reasonableness of economic remedies.

Adjustments to the conversion rate do not cover all dilutive events that may adversely affect the value of the notes.

The conversion rate of the notes is subject to adjustment for certain events, including, but not limited to, the issuance of stock dividends on our common stock, the issuance of certain rights, options or warrants, subdivisions, combinations, distributions of our capital stock, indebtedness, or assets, cash dividends and certain issuer tender or exchange offers as described under "Description of the Notes—Conversion Rights—Conversion Rate Adjustments." However, the conversion rate will not be adjusted for other events, such as a third-party tender or exchange offer or an issuance of common stock for cash or in connection with an acquisition, that may adversely affect the trading price of the notes or our common

stock. An event that adversely affects the value of the notes may occur and that event may not result in an adjustment to the conversion rate.

We may not have the ability to raise funds necessary to settle conversions of the notes or to purchase the notes upon a fundamental change.

If a fundamental change occurs, you will have the right, at your option, to require us to purchase for cash any or all of your notes, or any portion of the principal amount thereof such that the principal amount that remains outstanding of each note purchased in part equals $1,000 or an integral multiple of $1,000 in excess thereof. The fundamental change purchase price will equal 100% of the principal amount of the notes to be purchased, plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date. In addition, upon conversion of the notes, unless we elect to settle the conversion entirely in shares of our common stock, we will be required to make cash payments in respect of the notes being converted. However, we may not have sufficient funds at the time we are required to purchase the notes surrendered therefor or to make cash payments on the notes being converted and we may not be able to arrange necessary financing on acceptable terms, if at all. In addition, our ability to purchase the notes may be limited by law, by regulatory authority or by the agreements governing our other indebtedness outstanding at the time. If we fail to pay the fundamental change purchase price when due, or fail to pay any amount of cash due upon conversion within five business days of its due date, we will be in default under the indenture governing the notes. A default under the indenture or the fundamental change itself could also constitute a default under the agreements governing our other existing and future indebtedness which would further restrict our ability to make required payments under the notes. In particular, the occurrence of certain events that would constitute a fundamental change would also constitute an event of default under our existing credit agreements.

If an active trading market does not develop for the notes, you may not be able to resell them.

Prior to this offering, there was no public market for the notes, and we do not currently plan to list the notes on any securities exchange. If no active trading market develops, you may not be able to resell your notes at their fair market value or at all. The liquidity of the trading market in the notes and future trading prices of the notes will depend on many factors, including prevailing interest rates, our operating results and the market for similar securities. We have been informed by the representatives of the underwriters that certain underwriters currently intend to make a market in the notes after this offering is completed. However, such underwriters may cease their market-making at any time.

The conditional conversion features of the notes, if triggered, may adversely affect our financial condition.

If one of the conversion contingencies is triggered, holders of notes will be entitled to convert the notes at any time during specified periods. See "Description of the Notes—Conversion Rights." If one or more holders elect to convert their notes, unless we elect to satisfy our conversion obligation by delivering solely shares of common stock, we would be required to settle a portion of or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity and various aspects of our business (including our credit ratings and the trading price of the notes).

The conditional conversion feature of the notes could result in your receiving less than the value of the cash, shares of common stock or the cash and shares of common stock, if any, as the case may be, into which your notes would otherwise be convertible.

Prior to July 15, 2018, you may convert your notes only if specified conditions are met. If the specific conditions for conversion are not met, you will not be able to convert your notes, and you may not be able to receive the value of the cash, shares of common stock or combination of cash and shares of common stock, if any, as the case may be, into which your notes would otherwise be convertible. Therefore, you may not be able to realize the appreciation, if any, in the value of our common stock after the issuance of the notes in this offering and prior to such date. In addition, the inability to freely convert your notes may also adversely affect the trading price of the notes and your ability to resell the notes.

The settlement feature of the notes, as described under "Description of the Notes—Conversion Rights—Settlement Upon Conversion," may:

That is, unless we elect to settle the conversion entirely in shares of our common stock, upon conversion of the notes, you will, at our election, receive cash, or a combination of cash and shares of our common stock, based upon the volume weighted average prices of our common stock for each of the 40 trading days during the applicable cash settlement averaging period. As described under "Description of the Notes—Conversion Rights—Settlement Upon Conversion," this period means, for notes with a conversion date occurring on or after the 45th scheduled trading day before the maturity date, the 40 consecutive trading-day period beginning on, and including, the 42nd scheduled trading day prior to the maturity date (or, if such scheduled trading day is not a trading day, the immediately following trading day), and in all other instances, the 40 consecutive trading day period beginning on, and including, the third trading day immediately following the related conversion date. Accordingly, if the price of our common stock decreases during this period, the amount and/or value of consideration you receive will be adversely affected. Furthermore, because we may settle all or a portion of our conversion obligation in cash, the conversion of notes may significantly reduce our liquidity. See "Description of the Notes—Conversion Rights—Settlement Upon Conversion."

We may issue additional shares of our common stock or instruments convertible into our common stock, including in connection with conversions of notes, and thereby materially and adversely affect the price of our common stock, and, in turn, the notes.

Subject to lock-up provisions described under "Underwriting," we are not restricted from issuing additional shares of our common stock or other instruments convertible into our common stock during the life of the notes. See "Underwriting." We cannot predict the size of future issuances or the effect, if any, that they may have on the market price for our common stock. If we issue additional shares of our common stock or instruments convertible into our common stock, it may materially and adversely affect the price of our common stock and, in

turn, the price of the notes. Furthermore, the conversion or exercise of some or all of the notes may dilute the ownership interests of existing stockholders, and any sales in the public market of shares of our common stock issuable upon any such conversion or exercise could adversely affect prevailing market prices of our common stock or the notes. In addition, the anticipated issuance and sale of substantial amounts of common stock or the anticipated conversion or exercise of securities into shares of our common stock could depress the price of our common stock.

The accounting method for convertible debt securities that may be settled in cash, such as the notes, is the subject of recent changes that could have a material effect on our reported financial results.

In May 2008 (and effective for fiscal years beginning after December 15, 2008), the Financial Accounting Standards Board, which we refer to as FASB, issued FASB Staff Position No. APB 14-1, Accounting for Convertible Debt Instruments That May Be Settled in Cash Upon Conversion (Including Partial Cash Settlement), which we refer to as FSP APB 14-1 (and which subsequently was included under FASB Accounting Standards Codification Section, or ASC, 470-20, Debt with Conversion and other Options). Under ASC 470-20, an entity must separately account for the liability and equity components of the convertible debt instruments (such as the notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects the issuer's economic interest cost. The effect of ASC 470-20 on the accounting for the notes is that the equity component is required to be included in the additional paid-in capital section of equity on our consolidated balance sheets and the value of the equity component would be treated as original issue discount for purposes of accounting for the debt component of the notes. As a result, we will be required to record a greater amount of non-cash interest expense in current periods presented as a result of the accretion of the discounted carrying value of the notes to their face amount over the term of the notes. This could adversely affect our reported or future financial results, the market price of our common stock and the trading price of the notes. In addition, under certain circumstances, convertible debt instruments (such as the notes) that may be settled entirely or partly in cash are currently accounted for utilizing the treasury stock method, the effect of which is that the shares issuable upon conversion of the notes are not included in the calculation of diluted earnings per share except to the extent that the conversion value of the notes exceeds their principal amount. Under the treasury stock method, for diluted earnings per share purposes, the transaction is accounted for as if the number of shares of common stock that would be necessary to settle such excess, if we elected to settle such excess in shares, are issued. We cannot be sure that the accounting standards in the future will continue to permit the use of the treasury stock method. If we are unable to use the treasury stock method in accounting for the shares issuable upon conversion of the notes, then our diluted earnings per share would be adversely affected.

Holders of notes will not be entitled to any rights with respect to our common stock, but will be subject to all changes made with respect to our common stock to the extent our conversion obligations include shares of our common stock.

Holders of notes will not be entitled to any rights with respect to our common stock (including, without limitation, voting rights and rights to receive any dividends or other distributions on our common stock), until the time at which they become record holders of our common stock, which, if we deliver shares of common stock as part of our conversion obligation, will, if we elect to satisfy our conversion obligation by delivering solely shares of common stock, be the close of business on the conversion date, and otherwise will generally be the close of business on the last trading day of the applicable cash settlement averaging

period, but will be subject to all changes affecting our common stock. For example, if an amendment is proposed to our certificate of incorporation or bylaws requiring stockholder approval and the record date for determining the stockholders of record entitled to vote on the amendment occurs prior to the date you are deemed to be a record holder of our common stock, you generally will not be entitled to vote on the amendment, although you will nevertheless be subject to any changes affecting our common stock. In addition, because of the conditional conversion, and the settlement features of the notes, which would permit us to satisfy our obligation upon conversion solely in cash, should we elect to do so, you may not be able to convert your notes until July 15, 2018 and you may not receive any shares upon conversion.

Certain provisions in the notes and the indenture could delay or prevent an otherwise beneficial takeover or takeover attempt of us and, therefore, the ability of holders to exercise their rights associated with a potential fundamental change or a make-whole fundamental change.

Certain provisions in the notes and the indenture could make it more difficult or more expensive for a third party to acquire us. For example, if an acquisition event constitutes a fundamental change, holders of the notes will have the right to require us to purchase their notes in cash. In addition, if an acquisition event constitutes a make-whole fundamental change, we may be required to increase the conversion rate for holders who convert their notes in connection with such make-whole fundamental change. Our obligations under the notes and the indenture could increase the cost of acquiring us or otherwise discourage a third party from acquiring us or removing incumbent management.

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, 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:

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.

Ownership limitations in our charter may impair the ability of holders to convert notes into our common stock.

In order to assist us in maintaining our qualification as a REIT for U.S. federal income tax purposes, our charter restricts ownership of more than 9.8% by value or number of shares, whichever is more restrictive, of our outstanding shares of common stock, or of our outstanding capital stock, subject to certain exceptions. Notwithstanding any other provision of the notes, no holder of notes will be entitled to receive common stock following conversion of such notes to the extent that receipt of such common stock would cause such holder (after application of certain constructive ownership rules) to exceed the ownership limit contained in our charter. See "Description of Capital Stock—Restrictions on Ownership and Transfer" in the accompanying prospectus. If any delivery of shares of our common stock owed to a holder upon conversion of notes is not made, in whole or in part, as a result of the limitations described above, our obligation to make such delivery shall not be extinguished and we shall deliver such shares as promptly as practicable after any such converting holder gives notice to us that such delivery would not result in it being the beneficial or constructive owner of more than 9.8% (by value or number, whichever is more restrictive) of the shares of common stock, or of our outstanding capital stock, outstanding at such time. See "U.S. Federal Income Tax Considerations" in the accompanying prospectus.

We will not be able to deliver our common stock, even if we would otherwise choose to do so, to any holder of notes if the delivery of our common stock would cause that holder to exceed the ownership limits described above.

In addition to the risks relating to our acquisition of LNR described in our Annual Report on Form 10-K for the year ended December 31, 2012 and in our Current Report on Form 8-K filed on February 11, 2013, which are incorporated by reference into this prospectus supplement and the accompanying prospectus, we are also subject to the risk summarized below.

The unaudited pro forma combined financial statements relating to the LNR acquisition and incorporated by reference into this prospectus do not reflect the performance that we anticipate for future periods in the near-term.

We are required to prepare and incorporate by reference into this prospectus unaudited pro forma combined financial statements relating to the LNR acquisition. The unaudited pro forma combined financial statements are prepared and presented in accordance with U.S. generally accepted accounting principles and pursuant to specific requirements under federal securities laws. The unaudited pro forma combined balance sheet as of March 31, 2013 and

the unaudited pro forma combined statements of income for the year ended December 31, 2012 and the three months ended March 31, 2013 are based on our historical financial statements and the historical financial statements of LNR (after giving effect to our acquisition of LNR using the purchase method of accounting and adjustments described in the notes to the unaudited pro forma combined financial statements) as if such acquisition had occurred as of March 31, 2013 for pro forma balance sheet purposes and as of January 1, 2012 for pro forma income statement purposes.

We believe the unaudited pro forma combined statements of income incorporated into this prospectus are not indicative of our near-term future results of operations. In particular, LNR's revenues from special servicing are likely to decline in the near-term from the historical amounts reported in the unaudited pro forma combined statements of income due to a decrease in both the number of loans going into special servicing and the amount of revenues received from the resolution of loans currently in special servicing. In addition, we believe that the portion of income generated through fair value increases in the value of LNR's securities portfolio associated with improving CMBS credit spreads during the historical periods presented in these pro forma financial statements may not recur in future periods. Although in determining the pricing for the LNR acquisition we considered a near-term decline in revenues from loans in special servicing and the likelihood that the increase in fair value may not recur in future periods, there can be no assurance that the decline in revenues from special servicing that occurs will not exceed the decline that we anticipate in amount and duration or that the fair value of LNR's securities portfolio will not decline.

In the event that we determine to effect a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans, we may not be able to complete such a spin-off on the terms anticipated or at all.

As part of our continuing efforts to provide value to our stockholders, we are actively evaluating a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans. If this transaction were effected, we expect that the spin-off entity would elect to qualify to be taxed as a REIT and be externally managed by an affiliate of our manager. We also expect that the spin-off entity would apply to list its common equity on the New York Stock Exchange. However, a decision to effect this transaction is subject to a number of conditions, including, but not limited to, further approvals by our board of directors. In the event that our board of directors were to approve such a transaction, our ability to complete a spin-off would be subject to, among other things, the effectiveness of a registration statement filed with the SEC, the filing and approval of an application to list the spin-off entity's shares of common stock on the New York Stock Exchange and a formal declaration by our board of directors of a distribution in the form of the spin-off entity's shares of common stock. Stockholder approval would not be required in connection with the separation, and we would not require it. In the event that we determine to effect such a spin-off, there could be no assurance that the transaction would be completed on the terms anticipated or at all, and a failure to complete the spin-off could negatively affect the price of our common stock, and, in turn, the notes.

In the event that a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans occurs, such a spin-off may not have the benefits that we would have anticipated.

In the event that a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans occurs, such a spin-off may not have the full or

any strategic and financial benefits that we would have anticipated, or such benefits may be delayed or may not materialize at all. The anticipated benefits of a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans would be based on a number of assumptions, which may prove incorrect. For example, we believe that analysts and investors would regard the spin-off entity's investment strategy and asset portfolio more favorably as a separate company than as part of our existing portfolio and strategy and thus would place a greater value on the spin-off entity as a stand-alone REIT than as a business that is owned by us. In the event that a spin-off were not to have these and other expected benefits, the costs associated with the transaction, including its external manager's compensation and general and administrative expenses, could have a negative effect on the spin-off entity's financial condition and both the spin-off entity's and our ability to make distributions to the stockholders of each company.

In the event that a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans occurs, the spin-off entity may not be able to successfully implement its business strategy.

In the event that a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans occurs, there can be no assurance that the spin-off entity would be able to generate sufficient returns to pay its operating expenses and make satisfactory distributions to its stockholders, or any distributions at all, once it were to commence operations as an independent company. The spin-off entity's financial condition, results of operations and cash flows would be affected by the expenses it would incur as a stand-alone public company, including fees paid to its manager and legal, accounting, compliance and other costs associated with being a public company with equity securities traded on the New York Stock Exchange. In addition, the spin-off entity's results of operations and its ability to make or sustain distributions to its stockholders would depend on the availability of opportunities to acquire attractive assets, the level and volatility of interest rates, the availability of adequate short- and long-term financing, conditions in the real estate market, the financial markets and economic conditions, among other factors. After such a separation, we would not be required, and would not intend, to provide the spin-off entity with funds to finance its working capital or other cash requirements, so the spin-off entity would need to obtain additional financing from banks or through public offerings or private placements of debt or equity securities, strategic relationships or other arrangements.

In the event that a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans occurs, our agreements with the spin-off entity may not reflect terms that would have resulted from arm's-length negotiations among unaffiliated third parties.

In the event that a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans occurs, the terms of the agreements related to the spin-off entity's separation from us would not have been negotiated among unaffiliated third parties. As a result, the terms of these agreements may be less favorable to us than the terms that would have resulted from arm's-length negotiations among unaffiliated third parties.

In the event that a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans occurs, the distribution of the spin-off entity's shares of common stock would not qualify for tax-free treatment and may be taxable as a dividend to holders of our shares of common stock, including holders who received shares upon conversion of the notes.

In the event that a spin-off of our single-family rental homes and distressed and non-performing residential mortgage loans occurs, the distribution of the spin-off entity's

shares of common stock would not qualify for tax-free treatment. An amount equal to the fair market value of the shares received by a common stockholder, including any fractional shares deemed to be received, on the distribution date would be treated as a taxable dividend to the extent of a common stockholder's ratable share of any of our current or accumulated earnings and our profits, with the excess treated first as a non-taxable return of capital to the extent of a common stockholder's tax basis in our common stock and then as capital gain. In addition, we or other applicable withholding agents may be required or permitted to withhold at the applicable rate on all or a portion of the distribution that would be payable to non-U.S. stockholders, and any such withholding would be satisfied by us or such agent by withholding and selling a portion of the spin-off entity's stock that would be otherwise distributable to non-U.S. stockholders. Such non-U.S. stockholders may bear brokerage fees or other costs from this withholding procedure. A common stockholder's tax basis in our shares held at the time of the distribution would be reduced (but not below zero) to the extent the fair market value of the spin-off entity's shares distributed by us to a common stockholder in the distribution were to exceed such stockholder's ratable share of our then-current and accumulated earnings and profits. A common stockholder's holding period for our shares would not be affected by the distribution.

Although we would be ascribing a value to the spin-off entity's shares of common stock in the distribution for tax purposes, this valuation would not be binding on the Internal Revenue Service, or the IRS, or any other tax authority. These taxing authorities could ascribe a higher valuation to a common stockholder's shares, particularly if the spin-off entity's stock were to trade at prices significantly above the value ascribed to the shares by us in the period following the distribution. Such a higher valuation may cause a larger reduction in the tax basis of a common stockholder's shares of our common stock or may cause a common stockholder to recognize additional dividend or capital gain income.

Certain of the possible adjustments to the conversion rate may result in a deemed distribution from us to a holder of a note that will be taxable even though the holder does not receive a corresponding distribution of cash.

The conversion rate of the notes is subject to adjustment under certain circumstances. If certain of the possible adjustments to the conversion rate of the notes are made, a holder may be deemed to have received a taxable distribution from us even though the holder does not receive a corresponding distribution of cash. In particular, adjustments to the conversion rate pursuant to a spin-off will result in a deemed distribution (of an amount equal to the fair market value on the date of such deemed distribution of the additional number of shares into which a holder's notes are convertible), which will be taxable as a dividend to the extent of the allocable earnings or profits, if any, and treated as a return of capital (and reduction in a holder's tax basis) to the extent the fair market value exceeds the allocable share of earnings and profits. A deemed distribution to a Non-U.S. Holder (as defined under "Supplemental U.S. Federal Income Tax Considerations") may be subject to U.S. federal withholding tax, which may be set off against subsequent payments of cash and common stock. See "Supplemental U.S. Federal Income Tax Considerations."

The tax consequences of a conversion of notes for a combination of cash and shares of our common stock are unclear.

The amount of gain or loss that may be recognized upon a conversion of notes for a combination of cash and shares of our common stock is unclear. See "Supplemental U.S. Federal Income Tax Considerations."

Many of the assets that we acquired in the acquisition of LNR were acquired by, or are ownership interests in, entities subject to entity level or foreign taxes, which cannot be passed through to, or used by, our stockholders to reduce taxes they owe.

Most of the assets that we acquired in the acquisition of LNR are held through a taxable REIT subsidiary, or a TRS, which is subject to entity level taxes on income that it earns. Such taxes materially increase the taxes paid by our TRSs. In addition, certain of the assets that we acquired in the acquisition of LNR include entities organized or assets located in foreign jurisdictions. Taxes that we or such entities pay in foreign jurisdictions may not be passed through to, or used by, our stockholders as a foreign tax credit or otherwise.

We may choose to pay dividends in our own stock possibly requiring our stockholders to pay taxes in excess of the cash dividends they receive.

Although we have no current intention to do so, we may in the future distribute taxable dividends payable either in cash or shares of our stock at the election of each stockholder, but subject to a limitation on the amount of cash that may be distributed. Taxable stockholders receiving such dividends will be required to include the full amount of the dividend, whether received as cash or shares of our common stock, as ordinary income to the extent of our current and accumulated earnings and profits for U.S. federal income tax purposes. As a result, stockholders may be required to pay income taxes with respect to such dividends in excess of the cash dividends received.

We estimate that the net proceeds from this offering will be approximately $ million (or approximately $ million if the underwriters exercise their option to purchase additional notes to cover over-allotments, if any, in full), after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We intend to use the net proceeds from this offering to originate and purchase additional commercial mortgage loans and other target assets and investments. 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.

The following table sets forth our cash and cash equivalents and consolidated capitalization (i) as of March 31, 2013, (ii) as of March 31, 2013, on a pro forma basis to reflect the completion of our acquisition of LNR, and (iii) as of March 31, 2013, on a pro forma basis to reflect the completion of our acquisition of LNR, as adjusted to give effect to the sale of the $400,000,000 million principal amount of notes in this offering (assuming the underwriters' option to purchase additional notes is not exercised). You should read this table together with the unaudited pro forma combined financial statements incorporated in this prospectus supplement by reference to the Form 8-K/A filed with the SEC on June 27, 2013.

We will issue the notes under an indenture, which we refer to as the base indenture, dated as of February 11, 2013, between us and The Bank of New York Mellon, as trustee, which we refer to as the trustee, as supplemented by a supplemental indenture with respect to the notes, which we refer to as the supplemental indenture. We refer to the base indenture and the supplemental indenture, collectively, as the indenture. The terms of the notes include those expressly set forth in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended, which we refer to as the Trust Indenture Act.

You may request a copy of the indenture from us as described below under "Where You Can Find More Information."

The following description is a summary of the material provisions of the notes and (solely as it applies to the notes) the indenture and does not purport to be complete. This summary is subject to and is qualified by reference to all the provisions of the notes and the indenture, including the definitions of certain terms used in the indenture. We urge you to read these documents because they, and not this description, define your rights as a holder of the notes.

This description of the notes supplements and, to the extent it is inconsistent with, replaces the description of the general provisions of the notes and the base indenture in the accompanying prospectus. For purposes of this description, references to "Starwood Property Trust, Inc.," "we," "our" and "us" refer only to Starwood Property Trust, Inc. and not to its subsidiaries.

Subject to fulfillment of certain conditions and during the periods described below, the notes may be converted at a conversion rate initially equal to shares of common stock per $1,000 principal amount of notes (equivalent to a conversion price of

approximately $ per share of common stock). The conversion rate is subject to adjustment if certain events occur. See "—Conversion Rights—Conversion Rate Adjustments" and "—Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change."

Upon conversion of a note, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination thereof at our election as described below under "—Conversion Rights—Settlement Upon Conversion." Holders will not receive any additional cash payment for interest or additional interest, if any, accrued and unpaid to the conversion date except under the circumstances described below under "—Conversion Rights—General."

The indenture does not limit the amount of debt which may be issued by us or our subsidiaries under the indenture or otherwise. The indenture, as it relates to the notes, will not contain any financial covenants and will not restrict us from paying dividends or issuing or repurchasing our other securities. Other than the restrictions described under "—Consolidation, Merger and Sale of Assets" below and except for the provisions set forth under "—Fundamental Change Permits Holders to Require Us to Purchase Notes" and "—Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change," the indenture does not contain any covenants or other provisions designed to afford holders of the notes protection in the event we subsequently increase our borrowings substantially or engage in a transaction that substantially increases our debt to equity ratio (each of which would be an example of a highly leveraged transaction) or in the event of a decline in our credit rating for any reason, including as a result of a takeover, recapitalization, highly leveraged transaction or similar restructuring involving us that could adversely affect such holders.

We may, without notice to or the consent of the holders, issue additional notes under the indenture with the same terms and with the same CUSIP number as the notes offered hereby in an unlimited aggregate principal amount; provided that such additional notes must be part of the same issue (and part of the same series) as the notes offered hereby for federal income tax purposes. We may also from time to time repurchase notes in open market purchases or negotiated transactions without giving prior notice to holders. Any notes purchased by us will be retired and no longer outstanding under the indenture.

We do not intend to list the notes on any securities exchange or an interdealer quotation system.

Except to the extent the context otherwise requires, we use the term notes in this prospectus supplement to refer to each $1,000 principal amount of notes. We use the term "common stock" in this prospectus supplement to refer to our common stock, par value $0.01 per share. References in this prospectus supplement to a "holder" or "holders" of notes that are held through DTC are references to owners of beneficial interests in such notes, unless the context otherwise requires. However, we and the trustee will treat the person in whose name the notes are registered (Cede & Co., in the case of notes held through DTC) as the owner of such notes for all purposes.

We will pay principal of and interest on notes in global form registered in the name of or held by DTC or its nominee in immediately available funds to DTC or its nominee, as the case may be, as the registered holder of such global note. We will pay principal of any certificated notes at the office or agency designated by us for that purpose. We will pay interest on any certificated note by check mailed to the address of the registered holder of such note;

provided, however, that we will pay interest to any holder of more than $2,000,0000 aggregate principal amount of certificated notes by wire transfer in immediately available funds to an account within the United States designated by such holder in a written application delivered by such person to the trustee and the paying agent not later than the record date for the relevant interest payment, which application will remain in effect until such holder notifies the trustee and paying agent, in writing, to the contrary.

We have initially designated the trustee as our paying agent and registrar and its agency in New York, New York as a place where notes may be presented for payment or for registration of transfer. We may, however, change the paying agent or registrar without prior notice to the holders of the notes, and we may act as paying agent or registrar.

A holder of notes in global form may transfer its notes in accordance with the applicable procedures of the depositary and the indenture. A holder of certificated notes may transfer or exchange notes at the office of the registrar in accordance with the indenture. The registrar and the trustee may require a holder, among other things, to furnish appropriate endorsements and transfer documents. No service charge will be imposed by us, the trustee or the registrar for any registration of transfer or exchange of notes, but we may require a holder to pay a sum sufficient to cover any transfer tax or other similar governmental charge required by law or permitted by the indenture. We are not required to transfer or exchange any note surrendered for conversion or repurchase upon a fundamental change.

The notes will bear cash interest at a rate of % per year until maturity. Interest on the notes will accrue from the most recent date on which interest has been paid or duly provided for, or if no interest has been paid or duly provided for, the date of issuance (which is scheduled for July , 2013). Interest will be payable semiannually in arrears on January 15 and July 15 of each year, beginning on January 15, 2014.

Interest will be paid to the person in whose name a note is registered at the close of business on the January 1 or July 1, as the case may be, immediately preceding the relevant interest payment date. Interest on the notes will be computed on the basis of a 360-day year composed of twelve 30-day months.

If any interest payment date, the maturity date or any fundamental change purchase date of a note falls on a day that is not a business day, the required payment will be made on the next succeeding business day and no interest on such payment will accrue in respect of the delay. The term "business day" means any day other than a Saturday, a Sunday or a day on which the Federal Reserve Bank of New York is authorized or required by law or executive order to close or be closed.

Unless the context otherwise requires, all references to interest in this prospectus supplement include additional interest, if any, payable at our election as the sole remedy relating to the failure to comply with our reporting obligations as described under "—Events of Default."

The notes will be the direct unsecured obligations of Starwood Property Trust, Inc. and will not be guaranteed by any of our subsidiaries. The notes will rank equal in right of payment with all of our other existing and future unsecured and unsubordinated indebtedness, including our 4.55% convertible senior notes due 2018. The notes will be effectively subordinated to any of our existing and future secured indebtedness, to the extent of the value of our assets that secure such indebtedness. The notes will also be structurally

subordinated to all existing and future indebtedness (including trade payables) and preferred equity of our subsidiaries and to any of our existing and future indebtedness that may be guaranteed by our subsidiaries to the extent of any such guarantees unless and to the extent such subsidiaries in the future guarantee the notes in the manner described below under "—Future Subsidiary Guarantees."

As of March 31, 2013, our total consolidated indebtedness pro forma for our acquisition of LNR (excluding trade payables and unfunded commitments) was $2.1 billion, $458.4 million of which was secured indebtedness of ours to which the notes would have ranked effectively junior and $1.0 billion of which was indebtedness of our subsidiaries to third parties (excluding trade payables) to which the notes would have been structurally subordinated.

The indenture will provide that we will cause each subsidiary of ours that guarantees payment by us of any unsecured debt securities of ours issued by us in an offering registered pursuant to the Securities Act or in an offering exempt from such registration pursuant to Rule 144A and/or Regulation S thereunder to execute and deliver to the trustee a supplemental indenture pursuant to which such subsidiary will guarantee payment of the notes on terms substantially similar to the guarantee of such debt securities. The indenture will further provide that we may remove any such guarantee by any such subsidiary if such subsidiary no longer provides a guarantee with respect to any such debt securities.

Subject to certain exceptions, our charter restricts ownership of more than 9.8% by value or number of shares, whichever is more restrictive, of our outstanding shares of common stock, or of our outstanding capital stock, in order to protect our status as a REIT for U.S. federal income tax purposes. Notwithstanding any other provision of the notes, no holder of notes will be entitled to receive common stock following conversion of such notes to the extent that receipt of such common stock would cause such holder (after application of certain constructive ownership rules) to exceed the ownership limit contained in our charter.

If any delivery of shares of our common stock owed to a holder upon conversion of notes is not made, in whole or in part, as a result of the limitations described above, our obligation to make such delivery shall not be extinguished and we shall deliver such shares as promptly as practicable after any such converting holder gives notice to us that such delivery would not result in it being the beneficial or constructive owner of more than 9.8% (by value or number, whichever is more restrictive) of the shares of common stock, or of our outstanding capital stock, outstanding at such time.

Prior to the close of business on the business day immediately preceding July 15, 2018, the notes will be convertible only upon satisfaction of one or more of the conditions described under the headings "—Conversion Upon Satisfaction of Sale Price Condition," "—Conversion Upon Satisfaction of Trading Price Condition," and "—Conversion Upon Specified Corporate Events." On or after July 15, 2018 holders may convert each of their notes at the applicable conversion rate at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date irrespective of the foregoing conditions.

The conversion rate will initially equal shares of common stock per $1,000 principal amount of notes (equivalent to a conversion price of approximately $ per

share of common stock). Upon conversion of a note, we will satisfy our conversion obligation by paying or delivering, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election, all as set forth below under "—Settlement Upon Conversion." If we satisfy our conversion obligation solely in cash or through payment and delivery, as the case may be, of a combination of cash and shares of our common stock, the amount of cash and shares of common stock, if any, due upon conversion will be based on a "daily conversion value" (as defined below) calculated on a proportionate basis for each trading day in a 40 trading-day "cash settlement averaging period" (as defined below), all as set forth under "—Settlement Upon Conversion." If we elect to satisfy our conversion obligation solely in shares, we will deliver to the converting holder a number of shares of common stock equal to the product of (1) the aggregate principal amount of notes to be converted, divided by $1,000 and (2) the conversion rate, all as set forth under "—Settlement Upon Conversion." The trustee will initially act as the conversion agent.

The conversion rate and the equivalent conversion price in effect at any given time are referred to as the "applicable conversion rate" and the "applicable conversion price," respectively, and will be subject to adjustment as described below. A holder may convert less than the entire principal amount of its notes so long as the principal amount that remains outstanding of each note that is not converted in full equals $1,000 or an integral multiple of $1,000 in excess thereof.

If a holder of notes has submitted notes for purchase upon a fundamental change, the holder may convert those notes only if that holder first withdraws its purchase notice.

Upon conversion, you will not receive any separate cash payment for accrued and unpaid interest, if any (or dividends, if we declare any), except as described below. We will not issue fractional shares of our common stock upon conversion of notes. Instead, we will pay cash in lieu of fractional shares as described under "—Settlement Upon Conversion." Our payment or delivery, as the case may be, to you of the cash, shares of our common stock or combination of cash and shares of our common stock, together with any cash payment for any fractional share, into which your note is convertible, will be deemed to satisfy in full our obligation to pay:

As a result, accrued and unpaid interest, if any, to, but not including, the conversion date will be deemed to be paid in full rather than cancelled, extinguished or forfeited. Upon conversion of a note, accrued and unpaid interest will be deemed to be paid first out of any cash paid upon such conversion.

Notwithstanding the preceding paragraph, if notes are converted after 5:00 p.m., New York City time, on a record date for the payment of interest, holders of such notes at 5:00 p.m., New York City time, on such record date will receive the interest payable on such notes on the corresponding interest payment date notwithstanding the conversion. Notes, upon surrender for conversion during the period from 5:00 p.m., New York City time, on any record date to 9:00 a.m., New York City time, on the immediately following interest payment date must be accompanied by funds equal to the amount of interest payable on the notes so converted; provided that no such payment need be made:

If a holder converts notes, we will pay any documentary, stamp or similar issue or transfer tax due on the issue of any shares of our common stock upon the conversion, unless the tax is due because the holder requests any shares to be issued in a name other than the holder's name, in which case the holder will pay that tax.

Holders may surrender their notes for conversion, only under the following circumstances:

Prior to the close of business on the business day immediately preceding July 15, 2018, holders may surrender their notes for conversion during any fiscal quarter commencing after September 30, 2013 (and only during such fiscal quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day.

The "last reported sale price" of our common stock on any trading day means the closing sale price per share (or if no closing sale price is reported, the average of the last bid and last ask prices or, if more than one in either case, the average of the average last bid and the average last ask prices) on that trading day as reported in composite transactions for the principal U.S. national or regional securities exchange on which our common stock is traded. If our common stock is not listed for trading on a U.S. national or regional securities exchange on the relevant trading day, the "last reported sale price" will be the last quoted bid price for our common stock in the over-the-counter market on the relevant date as reported by OTC Markets Group Inc. or a similar organization. If our common stock is not so quoted, the "last reported sale price" will be the average of the mid-point of the last bid and last ask prices for our common stock on the relevant trading day from each of at least three nationally recognized independent investment banking firms selected by us for this purpose, which may include one or more of the underwriters. Any such determination will be conclusive absent manifest error.

"Trading day" means a scheduled trading day on which (i) trading in our common stock generally occurs on the New York Stock Exchange or, if our common stock is not then listed on the New York Stock Exchange, on the principal other United States national or regional securities exchange on which our common stock is then listed or, if our common stock is not then listed on a United States national or regional securities exchange, on the principal other market on which our common stock is then traded and (ii) there is no market disruption event. If our common stock is not so listed or traded, "trading day" means a "business day."

"Market disruption event" means, if our common stock is listed for trading on the New York Stock Exchange or listed on another U.S. national or regional securities exchange, the occurrence or existence during the one-half hour period ending on the scheduled close of trading on any trading day of any material suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the stock exchange or otherwise) in our common stock or in any options, contracts or futures contracts relating to our common stock.

Prior to the close of business on the business day immediately preceding July 15, 2018, a holder of notes may surrender all or a portion of its notes for conversion during the five business day period after any five consecutive trading day period, which we refer to as the measurement period, in which the "trading price" per $1,000 principal amount of notes, as determined following a request by a holder of notes in accordance with the procedures described below, for each trading day of that measurement period was less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate on such trading day.

The "trading price" of the notes on any date of determination means the average of the secondary market bid quotations obtained by the bid solicitation agent for $5.0 million principal amount of the notes at approximately 3:30 p.m., New York City time, on such determination date from three independent nationally recognized securities dealers we select, which may include one or more of the underwriters; provided that, if three such bids cannot reasonably be obtained by the bid solicitation agent but two such bids are obtained, then the average of the two bids shall be used, and if only one such bid can reasonably be obtained by the bid solicitation agent, that one bid shall be used. If the bid solicitation agent cannot reasonably obtain at least one bid for $5.0 million principal amount of the notes from a nationally recognized securities dealer, then the trading price per $1,000 principal amount of notes will be deemed to be less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate. Any such determination will be conclusive absent manifest error. If we do not so instruct the bid solicitation agent to obtain bids when required, or the bid solicitation agent fails to solicit bids when required, the trading price per $1,000 principal amount of the notes will be deemed to be less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate on each day we or it fails to do so. We will be the initial bid solicitation agent.

The bid solicitation agent (if other than us) shall have no obligation to determine the trading price of the notes unless we have requested such determination; and we shall have no obligation to make such request (or, if we are acting as bid solicitation agent, we shall have no obligation to determine the trading price) unless a holder of a note provides us with reasonable evidence that the trading price per $1,000 principal amount of notes would be less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate. At such time, we shall instruct the bid solicitation agent (if other than us) to determine, or if we are acting as bid solicitation agent, we shall determine, the trading price per $1,000 principal amount of the notes beginning on the next trading day and on each successive trading day until the trading price per $1,000 principal amount of notes is greater than or equal to 98% of the product of the last reported sale price of our common stock and the applicable conversion rate. If the trading price condition has been met, we will so notify the holders and the trustee. If, at any time after the trading price condition has been met, the trading price per $1,000 principal amount of notes is greater than or equal to 98% of the product of the last reported sale price of our common stock and the conversion rate for such date, we will so notify the holders and the trustee.

we must notify the holders of the notes at least 50 scheduled trading days prior to the ex-dividend date (as defined herein) for such issuance or distribution. Holders may surrender their notes for conversion at any time during the period beginning on the 45th scheduled trading day immediately prior to the ex-dividend date for such issuance or distribution and ending on the earlier of (i) 5:00 p.m., New York City time, on the business day immediately preceding such ex-dividend date or (ii) our announcement that such issuance or distribution will not take place, even if the notes are not otherwise convertible at such time. A holder may not convert any of its notes based on this conversion contingency if we provide that holders of the notes shall participate, at the same time and upon the same terms as holders of our common stock and as a result of holding the notes, in the relevant transaction described above without having to convert their notes as if they held a number of shares of common stock equal to the applicable conversion rate multiplied by the principal amount (expressed in thousands) of notes held by such holder.

If (i) a transaction or event that constitutes a "make-whole fundamental change" (as defined under "—Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change") occurs or (ii) we are a party to (a) a consolidation, merger, binding share exchange, pursuant to which our common stock would be converted into cash, securities or other assets or (b) a sale, conveyance, transfer or lease of all or substantially all of our assets, the notes may be surrendered for conversion at any time from or after the date which is 45 scheduled trading days prior to the anticipated effective date of the transaction (or, if later, the business day after we give notice of such transaction) until the close of business, (i) if such transaction or event is a fundamental change, on the business day immediately preceding the related fundamental change purchase date and (ii) otherwise, on the 35th business day immediately following the effective date of such transaction or event. We will notify holders and the trustee of such a transaction:

On or after July 15, 2018, a holder may convert any of its notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date regardless of the foregoing conditions.

If you hold a beneficial interest in a global note, to convert you must comply with DTC's procedures for converting a beneficial interest in a global note and, if required, pay funds equal to interest payable on the next interest payment date to which you are not entitled and, if required, pay all taxes or duties, if any. As such, if you are a beneficial owner of the notes, you must allow for sufficient time to comply with DTC's procedures if you wish to exercise your conversion rights.

We refer to the date you comply with the relevant procedures for conversion described above and any other procedures for conversion set forth in the indenture as the "conversion date."

If a holder has already delivered a purchase notice as described under "—Fundamental Change Permits Holders to Require Us to Purchase Notes" with respect to a note, the holder may not surrender that note for conversion until the holder has withdrawn the notice in accordance with the indenture, except to the extent that a portion of the holder's note is not subject to such fundamental change purchase notice.

Upon conversion, we may choose to deliver cash, shares of our common stock or a combination of cash and shares of our common stock, as described below.

All conversions during the period beginning on the 45th scheduled trading day prior to the maturity date and ending at 5:00 p.m., New York City time, on the second scheduled trading day immediately prior to the maturity date (the "final conversion period") will be settled in the same relative proportions of cash and/or shares of our common stock, which we refer to as the "settlement method." If we have not delivered a notice of our election of settlement method prior to the final conversion period we will be deemed to have elected combination settlement with the specified dollar amount (as defined below) of $1,000 as described below.

Prior to final conversion period, we will use the same settlement method for all conversions occurring on any given conversion date. Except for any conversions that occur during the final conversion period, we will not have any obligation to use the same settlement method with respect to conversions that occur on different conversion dates.

In other words, prior to the final conversion period we may choose on one conversion date to settle conversions in shares of our common stock only, and choose on another conversion date to settle in cash, shares of our common stock or a combination of cash and shares of our common stock. With respect to any conversion prior to the final conversion period, we will inform holders so converting through the trustee of the settlement method we have selected (including the specified dollar amount, if applicable) no later than the close of

business on the second trading day immediately following the related conversion date. If we do not inform holders of our election by the close of business on the second trading day immediately following the conversion date, we will be deemed to have elected combination settlement with the specified dollar amount of $1,000, as described in the third bullet point below.

The "daily settlement amount," for each of the 40 consecutive trading days during the cash settlement averaging period, will consist of:

"Daily conversion value" means, with respect to any note as to which cash settlement or combination settlement is applicable, for each of the 40 consecutive trading days during the cash settlement averaging period, one-fortieth (1/40th) of the product of (i) the applicable conversion rate on such trading day and (ii) the daily VWAP of our common stock on such trading day.

"Daily VWAP" means, with respect to any note as to which cash settlement or combination settlement is applicable, for any trading day, the per share volume-weighted average price as displayed under the heading "Bloomberg VWAP" on Bloomberg page "STWD.N <equity> AQR" (or its equivalent successor if such page is not available) in respect of the period from the scheduled open of trading until the scheduled close of trading of the primary trading session on such trading day (or if such volume-weighted average price is unavailable, the market value of one share of our common stock on such trading day determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained for this purpose by us). The "daily VWAP" will be determined without regard to after-hours trading or any other trading outside of the regular trading session trading hours.

"Cash settlement averaging period" means, with respect to any note as to which cash settlement or combination settlement is applicable, the 40 consecutive trading-day period beginning on, and including, the third trading day immediately following the related conversion date, except that "cash settlement averaging period" means, with respect to any conversion date occurring during the final conversion period, the 40 consecutive trading-day period beginning on, and including, the 42nd scheduled trading day prior to the maturity date.

For the purposes of determining amounts due upon conversion only, "trading day" means a day during which trading in our common stock generally occurs on the primary exchange or quotation system on which our common stock then trades or is quoted and there is no market disruption event.

For the purposes of determining amounts due upon conversion only, "market disruption event" means (1) a failure by the primary exchange or quotation system on which our common stock trades or is quoted to open for trading during its regular trading session or (2) the occurrence or existence, prior to 1:00 p.m., New York City time, on any trading day for our common stock, of an aggregate one half-hour period of any suspension or limitation imposed on trading (by reason of movements in price exceeding limits permitted by the stock exchange or otherwise) in our common stock or in any options, contracts or future contracts relating to our common stock.

We generally will deliver the conversion consideration in respect of any notes that you convert by the third trading day immediately following the last trading day of the cash settlement averaging period. However:

Notwithstanding the foregoing, if any information required in order to calculate the conversion consideration deliverable will not be available as of the applicable settlement date, we will deliver the additional shares of our common stock resulting from that adjustment on the third trading day after the earliest trading day on which such calculation can be made.

We will not issue fractional shares of our common stock upon conversion of notes. Instead, we will pay cash in lieu of fractional shares based on the daily VWAP of our common stock on the relevant conversion date (if we elect to satisfy our conversion obligation solely in shares of our common stock) or based on the daily VWAP of our common stock on the last trading day of the relevant cash settlement averaging period (in the case of any other settlement method).

Each conversion will be deemed to have been effected as to any notes surrendered for conversion on the conversion date; provided, however, that the person in whose name any shares of our common stock shall be deliverable upon such conversion will be treated as the holder of record of such shares as of the close of business on such conversion date (in the case of physical settlement) or the last trading day of the relevant cash settlement averaging period (in the case of any other settlement method).

The conversion rate will be adjusted as described below, except that we will not make any adjustments to the conversion rate if holders of the notes participate (other than in the case of a share split or share combination), at the same time and upon the same terms as holders of our common stock and as a result of holding the notes, in any of the transactions described below without having to convert their notes as if they held a number of shares of common stock equal to the applicable conversion rate, multiplied by the principal amount (expressed in thousands) of notes held by such holder.

CR₀ = the conversion rate in effect immediately prior to the open of business on the ex-dividend date of such dividend or distribution, or immediately prior to the open of business on the effective date of such share split or combination, as applicable;

CR₁ = the conversion rate in effect immediately after the open of business on such ex-dividend date or effective date;

OS₀ = the number of shares of our common stock outstanding immediately prior to the open of business on such ex-dividend date or effective date, as applicable, before giving effect to such dividend, distribution, share split or share combination; and

OS₁ = the number of shares of our common stock outstanding immediately after giving effect to such dividend, distribution, share split or share combination, as applicable.

Any adjustment made under this clause (1) shall become effective immediately after the open of business on the ex-dividend date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination. If any dividend or distribution of the type described in this clause (1) is declared but not so paid or made, the conversion rate shall be immediately readjusted, effective as of the date our board of directors, or a committee thereof, determines not to pay such dividend or distribution to the conversion rate that would then be in effect if such dividend or distribution had not been declared.

CR₀ = the conversion rate in effect immediately prior to the open of business on the ex-dividend date for such issuance;

CR₁ = the conversion rate in effect immediately after the open of business on such ex-dividend date;

OS₀ = the number of shares of our common stock outstanding immediately prior to the open of business on such ex-dividend date;

X = the total number of shares of our common stock issuable pursuant to such rights, options or warrants; and

Y = the number of shares of our common stock equal to the aggregate price payable to exercise such rights, options or warrants divided by the average of the last reported sale prices of our common stock over the 10 consecutive trading-day period ending on the trading day immediately preceding the date of announcement of the issuance of such rights, options or warrants.

Any increase made under this clause (2) will be made successively whenever any such rights, options or warrants are issued and shall become effective immediately after the open of business on the ex-dividend date for such issuance. To the extent that such rights, options or warrants are not exercised prior to their expiration or shares of common stock are not delivered upon the expiration of such rights, options or warrants, the conversion rate shall be readjusted to the conversion rate that would then be in effect had the increase with respect to the issuance of such rights, options or warrants been made on the basis of delivery of only the number of shares of common stock actually delivered. If such rights, options or warrants are not so issued, or if no such rights, options or warrants are exercised prior to their expiration, the conversion rate shall be decreased to be the conversion rate that would then be in effect if such ex-dividend date for such issuance had not occurred.

For purposes of this clause (2) and for purposes of the provisions set forth above under "—Conversion Upon Specified Corporate Events—Certain Distributions," in determining whether any rights, options or warrants entitle the holders to subscribe for or purchase shares of the common stock at a price per share less than such average of the last reported sale prices of our common stock for the 10 consecutive trading day period ending on the trading day immediately preceding the date of announcement for such issuance, and in determining the aggregate offering price of such shares of the common stock, there shall be taken into account any consideration received by us for such rights, options or warrants and any amount payable on exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by our board of directors, or a committee thereof.

CR₀ = the conversion rate in effect immediately prior to the open of business on the ex-dividend date for such distribution;

CR₁ = the conversion rate in effect immediately after the open of business on such ex-dividend date;

SP₀ = the average of the last reported sale prices of our common stock over the 10 consecutive trading day period ending on, and including, the trading day immediately preceding the ex-dividend date for such distribution; and

FMV = the fair market value (as determined by our board of directors, or a committee thereof) of the shares of capital stock, evidences of indebtedness, other assets, or property of ours or rights, options or warrants to acquire our capital stock or other securities distributed with respect to each outstanding share of our common stock on the ex-dividend date for such distribution.

If "FMV" (as defined above) is equal to or greater than the "SP₀" (as defined above), in lieu of the foregoing increase, each holder of a note shall receive, in respect of each $1,000 principal amount of notes it holds, at the same time and upon the same terms as holders of our common stock, the amount and kind of our capital stock, evidences of our indebtedness, other assets or property of ours or rights, options or warrants to acquire our capital stock or other securities that such holder would have received as if such holder owned a number of shares of common stock equal to the conversion rate in effect on the ex-dividend date for the distribution.

Any increase made under the portion of this clause (3) above will become effective immediately after the open of business on the ex-dividend date for such distribution. If such distribution is not so paid or made, the conversion rate shall be decreased to be the conversion rate that would then be in effect if such dividend or distribution had not been declared.

With respect to an adjustment pursuant to this clause (3) where there has been a payment of a dividend or other distribution on our common stock of shares of capital stock of any class or series, or similar equity interest, of or relating to our subsidiary or other business unit, and such capital stock or similar equity interest is listed or quoted (or will be listed or quoted upon the consummation of the distribution) on a United States national securities exchange, which we refer to as a "spin-off," the conversion rate will be increased based on the following formula:

CR₀ = the conversion rate in effect immediately prior to the open of business on the ex-dividend date for such spin-off;

CR₁ = the conversion rate in effect immediately after the open of business on the ex-dividend date for such spin-off;

FMV₀ = the average of the last reported sale prices of the capital stock or similar equity interest distributed to holders of our common stock applicable to one share of our common stock over the first ten (10) consecutive trading-day period after, and including, the effective date of the spin-off (the "valuation period"); and

MP₀ = the average of the last reported sale prices of our common stock over the valuation period.

The adjustment to the applicable conversion rate under the preceding paragraph of this clause (3) will be made immediately after the open of business on the day after the last day of the valuation period, but will be given effect as of the open of business on the ex-dividend date for the spin-off. If the ex-dividend date for the spin-off is less than 10 trading days prior to, and including, the end of the cash settlement averaging period in respect of any conversion, references within this clause (3) to 10 trading days shall be deemed replaced, for purposes of calculating the affected daily conversion values in respect of that conversion, with such lesser number of trading days as have elapsed from, and including, the ex-dividend date for the spin-off to, and including, the last trading day of such cash settlement averaging period. For purposes of determining the applicable conversion rate, in respect of any conversion during the 10 trading days commencing on the ex-dividend date for any spinoff, references within the portion of this clause (3) related to "spin-offs" to 10 trading days shall be deemed replaced with such lesser number of trading days as have elapsed from, and including, the ex-dividend date for such spin-off to, and including, the relevant conversion date.

CR₀ = the conversion rate in effect immediately prior to the open of business on the ex-dividend date for such dividend or distribution;

CR₁ = the conversion rate in effect immediately after the open of business on the ex-dividend date for such dividend or distribution;

SP₀ = the last reported sale price of our common stock on the trading day immediately preceding the ex-dividend date for such dividend or distribution;

DTA = the dividend threshold amount, which shall initially be $0.46 per quarter; and

C = the amount in cash per share that we distribute to holders of our common stock in excess of the DTA.

The DTA is subject to adjustment on an inversely proportional basis whenever the conversion rate is adjusted other than adjustments made pursuant to this clause (4). If an adjustment is required to be made as set forth in this clause (4) as a result of a distribution that is not a regular quarterly dividend, the DTA will be deemed to be zero with respect to that particular adjustment.

If "C" (as defined above) is equal to or greater than "SP₀" (as defined above), in lieu of the foregoing increase, each holder of a note shall receive, for each $1,000 principal amount of notes it holds, at the same time and upon the same terms as holders of shares of our common stock, the amount of cash that such holder would have received as if such holder owned a number of shares of our common stock equal to the conversion rate on the ex-dividend date for such cash dividend or distribution. Such increase shall become effective immediately after the open of business on the ex-dividend date for such dividend or distribution. If such dividend or distribution is not so paid, the conversion rate shall be

decreased to be the conversion rate that would then be in effect if such dividend or distribution had not been declared.

CR₀ = the conversion rate in effect immediately prior to the close of business on the expiration date;

CR₁ = the conversion rate in effect immediately after the close of business on the expiration date;

AC = the aggregate value of all cash and any other consideration (as determined by our board of directors, or a committee thereof) paid or payable for shares purchased in such tender or exchange offer;

OS₀ = the number of shares of our common stock outstanding immediately prior to the expiration time of the tender or exchange offer on the expiration date (prior to giving effect to the purchase of all shares accepted for purchase or exchange in such tender offer or exchange offer);

OS₁ = the number of shares of our common stock outstanding immediately after the expiration time of the tender or exchange offer on the expiration date (after giving effect to the purchase of all shares accepted for purchase or exchange in such tender or exchange offer); and

SP₁ = the average of the last reported sale prices of our common stock over the ten (10) consecutive trading-day period commencing on the trading day next succeeding the expiration date (the "averaging period").

The adjustment to the applicable conversion rate under the preceding paragraph of this clause (5) will be given effect at the open of business on the trading day next succeeding the expiration date. If the trading day next succeeding the expiration date is less than 10 trading days prior to, and including, the end of the cash settlement averaging period in respect of any conversion, references within this clause (5) to 10 trading days shall be deemed replaced, for purposes of calculating the affected daily conversion values in respect of that conversion, with such lesser number of trading days as have elapsed from, and including, the trading day next succeeding the expiration date to, and including, the last trading day of such cash settlement averaging period. For purposes of determining the applicable conversion rate, in respect of any conversion during the 10 trading days commencing on the trading day next succeeding the expiration date, references within this clause (5) to 10 trading days shall be deemed replaced with such lesser number of trading days as have elapsed from, and including, the trading day next succeeding the expiration date to, and including, the relevant conversion date.

Notwithstanding anything to the contrary herein with respect to converted notes as to which cash or combination settlement is applicable, if a holder converts a note and the daily

settlement amount for any trading day during the cash settlement averaging period applicable to such note:

then, although we will otherwise treat such holder as the holder of record of such shares of our common stock on the last trading day of such cash settlement averaging period, we will not permit such holder to participate in such event on account of such shares of our common stock.

In addition, if a holder converts a note to which cash or combination settlement is applicable and:

then, on account of such conversion, we will, on such record date, effective date or expiration date, treat such holder, as a result of having converted such notes, as though it were the record holder of a number of shares of common stock equal to the total number of shares of common stock that:

In addition, and notwithstanding the foregoing, with respect to any notes as to which physical settlement is applicable, if a conversion rate adjustment becomes effective on any ex-dividend date as described above, and a holder that has converted its notes on or after such ex-dividend date and on or prior to the related record date would be treated as the record holder of shares of our common stock as of the related conversion date as described above under "—Settlement upon Conversion" based on an adjusted conversion rate for such ex-dividend date, then, notwithstanding the foregoing conversion rate adjustment provisions, the conversion rate adjustment relating to such ex-dividend date will not be made for such converting holder. Instead, such holder will be treated as if such holder were the record owners of the shares of our common stock on an unadjusted basis and participate in the related dividend, distribution or other event giving rise to such adjustment.

Except as stated herein, we will not adjust the conversion rate for the issuance of shares of our common stock or any securities convertible into or exchangeable for shares of our

common stock or the right to purchase shares of our common stock or such convertible or exchangeable securities. If, however, the application of the foregoing formulas would result in a decrease in the conversion rate, except to the extent of any readjustment to the conversion rate, no adjustment to the conversion rate will be made (other than as a result of a reverse share split, share combination or readjustment).

"Ex-dividend date" means the first date on which the shares of our common stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive the issuance, dividend or distribution in question.

To the extent permitted by applicable law, we are permitted to increase the conversion rate of the notes by any amount for a period of at least 20 business days if our board of directors, or a committee thereof, determines that such increase would be in our best interest. We may also (but are not required to) increase the conversion rate to avoid or diminish income tax to holders of our common stock or rights to purchase shares of our common stock in connection with a dividend or distribution of shares (or rights to acquire shares) or similar event.

A holder may, in some circumstances, including a distribution of cash dividends to holders of our shares of common stock, be deemed to have received a distribution subject to United States federal income tax as a result of an adjustment or the nonoccurrence of an adjustment to the conversion rate. For a discussion of the United States income tax treatment of an adjustment to the conversion rate, see "Supplemental U.S. Federal Income Tax Considerations."

We do not currently have a rights plan in effect. If you convert a note, to the extent that we have a rights plan in effect, you will receive, in addition to any shares of common stock received in connection with such conversion, the rights under the rights plan unless the rights have separated from the common stock, in which case, and only in such case, the conversion rate will be adjusted at the time of separation as if we distributed to all holders of our common stock, shares of our capital stock, evidences of indebtedness, assets, property, rights, options or warrants as described in clause (3) above, subject to readjustment in the event of the expiration, termination or redemption of such rights.

Notwithstanding any of the foregoing, the applicable conversion rate will not be adjusted:

Notwithstanding anything to the contrary herein, except on and after the first trading day of any cash settlement averaging period with respect to a note and on or prior to the last trading day of such cash settlement averaging period, we will not be required to adjust the conversion rate unless such adjustment would require an increase or decrease of at least one percent; provided, however, that any such minor adjustments that are not required to be made will be carried forward and taken into account in any subsequent adjustment, and provided, further, that any such adjustment of less than one percent that has not been made shall be made upon the occurrence of (i) the effective date for any make-whole fundamental change, (ii) the first trading day of any cash settlement averaging period and (iii) if we elect to satisfy our conversion obligation solely in shares of our common stock, upon any conversion of notes. In addition, we shall not account for such deferrals when determining whether any of the conditions to conversion have been satisfied or what number of shares of our common stock a holder would have held on a given day had it converted its notes.

Adjustments to the applicable conversion rate will be calculated to the nearest 1/10,000^th of a share.

and, in each case, as a result of which our common stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof), then, at the effective time of the transaction, the right to convert each $1,000 principal amount of notes based on a number of shares of common stock equal to the conversion rate will be changed into a right to convert such principal amount of notes based on the kind and amount of shares of stock, other securities or other property or assets (including cash or any combination thereof), which stock, other securities or other property or assets we refer to as the reference property, that a holder of a number of shares of common stock equal to the conversion rate immediately prior to such transaction would have owned or been entitled to receive upon such transaction. However, at and after the effective time of the transaction, (i) we will continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, as described above under "—Conversion Rights—Settlement Upon Conversion," and (ii)(x) any amount payable in cash upon conversion of the notes as set forth under "—Conversion Rights—Settlement Upon Conversion" will continue to be payable in cash, (y) any shares of our common stock that we would have been required to deliver upon conversion of the notes as set forth under "—Conversion Rights—Settlement Upon Conversion" will instead be deliverable in the amount and type of reference property that a holder of that number of shares of our common stock would have received in such transaction and (z) the daily VWAP will be calculated based on the value of the amount and kind of reference property that a holder of one share of our common stock would have

received in such transaction. If the transaction causes our common stock to be converted into, or exchanged for, the right to receive more than a single type of consideration (determined based in part upon any form of stockholder election), the amount and type of reference property that a holder of one or more shares would have been entitled to receive in such transaction (and into which the notes will be convertible) will be deemed to be based on the weighted average of the types and amounts of consideration received by the holders of our common stock that affirmatively make such an election. We will notify holders of the weighted average as soon as practicable after such determination is made. We will agree in the indenture not to become a party to any such transaction unless its terms are consistent with the foregoing.

Whenever any provision of the indenture requires us to calculate the last reported sale prices, the daily VWAPs or any function thereof over a span of multiple days (including during a cash settlement averaging period), we will make appropriate adjustments to each to account for any adjustment to the conversion rate that becomes effective, or any event requiring an adjustment to the conversion rate where the effective date, ex-dividend date or expiration date of the event occurs, at any time during the period when the last reported sale prices, the daily VWAPs or functions thereof are to be calculated.

Adjustment to Conversion Rate Upon Conversion in Connection with a Make-Whole Fundamental Change

If an event occurs that (i) is a fundamental change (as defined below and determined after giving effect to any exceptions or exclusions to such definition) or (ii) would be a fundamental change, but for the exclusion in section (i) of clause (2) of the definition thereof (any such event, a "make-whole fundamental change"), and a holder elects to convert its notes in connection with such make-whole fundamental change, we will, under certain circumstances, increase the conversion rate for the notes so surrendered for conversion by a number of additional shares of common stock, which we refer to as the additional shares, as described below. A conversion of notes will be deemed for these purposes to be "in connection with" a make-whole fundamental change if the notice of conversion of the notes is received by the conversion agent from, and including, the effective date of the fundamental change up to, and including, the close of business on the business day immediately prior to the related fundamental change purchase date, or, if such make-whole fundamental change is not also a fundamental change, the 35th business day immediately following the effective date for such make-whole fundamental change.

Notwithstanding anything to the contrary herein, if the consideration paid for our common stock in any make-whole fundamental change described in clause (2) of the definition of fundamental change is comprised entirely of cash, for any conversion of notes following the effective date of such make-whole fundamental change, the settlement amount will be calculated based solely on the "stock price" (as defined below) for the transaction and will be deemed to be an amount equal to the applicable conversion rate (including any adjustment as described in this section), multiplied by such stock price. In such event, the settlement amount will be determined and paid to holders in cash on the third business day following the conversion date. Otherwise, we will settle any conversion of notes following the effective date of a make-whole fundamental change as described above under "—Conversion Rights—Settlement Upon Conversion." We will notify holders of the effective date of any make-whole fundamental change and issue a press release announcing such effective date no later than five business days after such effective date.

The number of additional shares, if any, by which the conversion rate will be increased will be determined by reference to the table below, based on the date on which the make-whole fundamental change occurs or becomes effective, which we refer to as the effective date, and the price, which we refer to as the stock price, paid (or deemed paid) per share of our common stock in the make-whole fundamental change. If the holders of our common stock receive only cash in a make-whole fundamental change described in clause (2) of the definition of fundamental change, the stock price shall be the cash amount paid per share. Otherwise, the stock price shall be the average of the last reported sale prices of our common stock over the ten trading day period ending on, and including, the trading day immediately preceding the effective date of the make-whole fundamental change.

The stock prices set forth in the column headings of the table below will be adjusted as of any date on which the conversion rate of the notes is otherwise required to be adjusted. The adjusted stock prices will equal the stock prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the conversion rate immediately prior to the adjustment giving rise to the stock price adjustment and the denominator of which is the conversion rate as so adjusted. The number of additional shares will be adjusted in the same manner and at the same time as the conversion rate is required to be adjusted as set forth under "—Conversion Rights—Conversion Rate Adjustments."

The following table sets forth the number of additional shares by which we will increase the conversion rate for a holder that converts its notes in connection with a make-whole fundamental change having the stock price and effective date set forth below:

The exact stock prices and effective dates may not be set forth in the table above, in which case:

Notwithstanding the foregoing, in no event will the conversion rate be increased on account of a make-whole fundamental change to exceed share s of common stock per $1,000 principal amount of notes, subject to adjustments in the same manner as the conversion rate is required to be adjusted as set forth under "—Conversion Rights—Conversion Rate Adjustments."

Our obligation to satisfy the additional shares requirement could be considered a penalty, in which case the enforceability thereof could be subject to general equity principles including principles of reasonableness and equitable remedies.

If a "fundamental change" (as defined below in this section) occurs at any time, you will have the right, at your option, to require us to purchase for cash any or all of your notes, or any portion thereof such that the principal amount that remains outstanding of each note that is not purchased in full equals $1,000 or an integral multiple of $1,000 in excess thereof. The price we are required to pay, which we refer to as the fundamental change purchase price, will be equal to 100% of the principal amount of the notes to be purchased plus accrued and unpaid interest, if any, to but excluding the fundamental change purchase date (unless the fundamental change purchase date is after a record date and on or prior to the interest payment date to which such record date relates, in which case we will instead pay the full amount of accrued and unpaid interest to the holder of record on such record date and the fundamental change purchase price will be equal to 100% of the principal amount of the notes to be purchased). The fundamental change purchase date will be a date specified by us that is not less than 20 or more than 35 calendar days following the date of our fundamental change notice as described below. Any notes purchased by us will be paid for in cash.

A "fundamental change" will be deemed to have occurred at the time after the notes are originally issued if any of the following occurs:

provided, however, that in the case of a transaction or event described in clause (1) or (2) above, if at least 90% of the consideration received or to be received by holders of the common stock (excluding cash payments for fractional shares) in the transaction or transactions that would otherwise constitute a "fundamental change" consists of shares of common stock or common equity interests that are traded on The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors) or that will be so traded when issued or exchanged in connection with the transaction that would otherwise constitute a fundamental change under clause (1) or (2) of the definition thereof, which we refer to as publicly traded securities, and as a result of such transaction or transactions, the notes become convertible into or by reference to such publicly traded securities, excluding cash payments for fractional shares (subject to settlement in accordance with the provisions of "—Conversion Rights—Settlement Upon Conversion"), such event shall not be a fundamental change.

"Continuing director" means a director who either was a member of our board of directors on the date of this offering memorandum or who becomes a member of our board of directors subsequent to that date and whose election, appointment or nomination for election by our shareholders is duly approved by a majority of the continuing directors on our board of directors at the time of such approval, either by a specific vote or by approval of the proxy statement issued by us on behalf of our entire board of directors in which such individual is named as nominee for director.

On or before the 20th day after the occurrence of a fundamental change, we will provide to all holders of the notes and the trustee and paying agent a notice of the occurrence of the fundamental change and of the resulting purchase right. Such notice shall state, among other things:

Simultaneously with providing such notice, we will publish a notice containing this information in a newspaper of general circulation in The City of New York or publish the information on our website or through such other public medium as we may use at that time.

To exercise the fundamental change purchase right, you must deliver, on or before the business day immediately preceding the fundamental change purchase date, the notes to be purchased, duly endorsed for transfer, together with a written purchase notice and the form entitled "Form of Fundamental Change Purchase Notice" on the reverse side of the notes duly

completed, to the paying agent if the notes are certificated. If the notes are not in certificated form, you must comply with DTC's procedures for tendering interests in global notes. Your purchase notice must state:

You may withdraw any purchase notice (in whole or in part) by a written notice of withdrawal delivered to the paying agent prior to the close of business on the business day immediately preceding the fundamental change purchase date. The notice of withdrawal shall state:

We will be required to purchase the notes on the fundamental change purchase date, subject to extensions to comply with applicable law. You will receive payment of the fundamental change purchase price on the later of (i) the fundamental change purchase date or (ii) the time of book-entry transfer or the delivery of the notes. If the paying agent holds money sufficient to pay the fundamental change purchase price of the notes on the fundamental change purchase date, then:

In connection with any purchase offer pursuant to a fundamental change purchase notice, we will, if required:

If a fundamental change were to occur, we may not have sufficient funds to pay the fundamental change purchase price. No notes may be purchased at the option of holders upon a fundamental change if the principal amount of the notes has been accelerated, and such acceleration has not been rescinded, on or prior to such date (except in the case of an

acceleration resulting from a default by us in the payment of the fundamental change purchase price with respect to such notes).

The purchase rights of the holders could discourage a potential acquirer of us. The fundamental change purchase feature, however, is not the result of management's knowledge of any specific effort to obtain control of us by any means or part of a plan by management to adopt a series of anti-takeover provisions.

The term fundamental change is limited to specified transactions and may not include other events that might adversely affect our financial condition. In addition, the requirement that we offer to purchase the notes upon a fundamental change may not protect holders in the event of a highly leveraged transaction, reorganization, merger or similar transaction involving us.

The definition of fundamental change includes a phrase relating to the conveyance, transfer, sale, lease or disposition of "all or substantially all" of our consolidated assets. There is no precise, established definition of the phrase "substantially all" under applicable law. Accordingly, the ability of a holder of the notes to require us to purchase its notes as a result of the conveyance, transfer, sale, lease or other disposition of less than all of our assets may be uncertain.

If a fundamental change were to occur, we may not have enough funds to pay the fundamental change purchase price. Our ability to repurchase the notes for cash may be limited by restrictions on our ability to obtain funds for such repurchase through dividends from our subsidiaries, the terms of our then existing borrowing arrangements or otherwise. See "Risk Factors—Risks Related to the Notes and to this Offering—We may not have the ability to raise funds necessary to settle conversions of the notes or to purchase the notes upon a fundamental change." If we fail to purchase the notes when required following a fundamental change, we will be in default under the indenture. In addition, we have, and may in the future incur, other indebtedness with similar change in control provisions permitting our holders to accelerate or to require us to purchase our indebtedness upon the occurrence of similar events or on some specific dates.

Notwithstanding anything to the contrary set forth under "Description of Debt Securities—Merger, Consolidation or Sale" in the accompanying prospectus, the indenture provides that we shall not amalgamate or consolidate with, merge with or into, or convey, transfer or lease our properties and assets substantially as an entirety to another person, unless (i) we are the surviving person or the resulting, surviving or transferee person (if not us) is organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and such person (if not us) shall expressly assume, by supplemental indenture, executed and delivered to the trustee, in form satisfactory to the trustee, all of our obligations under the notes and the indenture; and (ii) immediately after giving effect to such transaction, no default or event of default has occurred and is continuing under the indenture with respect to the notes. Upon any such amalgamation, consolidation, merger, conveyance, transfer or lease, the resulting, surviving or transferee person (if not us) shall succeed to, and may exercise every right and power of ours under the indenture, and we shall be discharged from our obligations under the notes and the indenture except in the case of any such lease.

Although these types of transactions are permitted under the indenture, certain of the foregoing transactions could constitute a fundamental change permitting each holder to require us to purchase the notes of such holder as described above.

The following description replaces the description set forth under "Description of Debt Securities—Events of Default, Notice and Waiver" in the accompanying prospectus in its entirety.

If an event of default other than an event of default arising under clause (8) above with respect to us occurs and is continuing, the trustee by notice to us, or the holders of at least 25% in principal amount of then outstanding notes by notice to us and the trustee, may, and the trustee at the request of such holders shall, declare 100% of the principal of, and accrued and unpaid interest, if any, on, all then outstanding notes to be due and payable. In addition, upon an event of default arising under clause (8) above with respect to us, 100% of the principal of and accrued and unpaid interest on the notes will automatically become due and payable. Upon any such acceleration, the principal of and accrued and unpaid interest, if any, on the notes will be due and payable immediately.

The holders of a majority in principal amount of the outstanding notes may waive (including, by way of consents obtained in connection with a repurchase of, or tender or exchange offer for, the notes) all past defaults (except with respect to nonpayment of principal or interest, the failure to deliver the consideration due upon conversion or any other provision that requires the consent of each affected holder to amend), and rescind any acceleration with

respect to the notes and its consequences if (i) rescission would not conflict with any judgment or decree of a court of competent jurisdiction and (ii) all existing events of default, other than the nonpayment of the principal of and interest on the notes that have become due solely by such declaration of acceleration, have been cured or waived.

Notwithstanding the foregoing, the indenture will provide that, to the extent we elect, the sole remedy for an event of default relating to (i) our failure to file with the trustee pursuant to Section 314(a)(1) of the Trust Indenture Act any documents or reports that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act or (ii) our failure to comply with our obligations as set forth under "—Reports" below, will after the occurrence of such an event of default consist exclusively of the right to receive additional interest on the notes at a rate equal to (x) 0.25% per annum of the principal amount of the notes outstanding for the first 90 days of the 180-day period on which such event of default is continuing beginning on, and including, the date on which such an event of default first occurs and (y) 0.50% per annum of the principal amount of the notes outstanding for the last 90 days of such 180-day period as long as such event of default is continuing. If we so elect, such additional interest will be payable in the same manner and on the same dates as the stated interest payable on the notes. On the 181st day after such event of default (if the event of default relating to the reporting obligations is not cured or waived prior to such 181st day), the notes will be subject to acceleration as provided above. The provisions of the indenture described in this paragraph will not affect the rights of holders of notes in the event of the occurrence of any other event of default. In the event we do not elect to pay the additional interest following an event of default in accordance with this paragraph or we elected to make such payment but do not pay the additional interest when due, the notes will be immediately subject to acceleration as provided above.

In order to elect to pay the additional interest as the sole remedy during the first 180 days after the occurrence of an event of default relating to the failure to comply with the reporting obligations in accordance with the immediately preceding paragraph, we must notify all holders of notes, the trustee and the paying agent of such election prior to the beginning of such 180-day period. Upon our failure to timely give such notice, the notes will be immediately subject to acceleration as provided above.

If any portion of the amount payable on the notes upon acceleration is considered by a court to be unearned interest (through the allocation of the value of the instrument to the embedded warrant or otherwise), the court could disallow recovery of any such portion.

Subject to the provisions of the indenture relating to the duties of the trustee, if an event of default occurs and is continuing, the trustee will be under no obligation to exercise any of the rights or powers under the indenture at the request or direction of any of the holders unless such holders have offered to the trustee indemnity or security reasonably satisfactory to it against any loss, liability or expense. In addition, except to enforce the right to receive payment of the principal of, or interest on, or fundamental change purchase price with respect to, its notes when due, or the right to receive payment or delivery of the consideration due upon conversion of its notes, no holder may pursue any remedy with respect to the indenture or the notes unless:

However, each holder shall have the right, which is absolute and unconditional, to receive the principal of, interest on, fundamental change purchase price with respect to, and the amount of cash or the combination of cash and shares of common stock, if any, as the case may be, due upon conversion of its notes and to institute suit for the enforcement of any such payment or delivery, as the case may be, and such rights shall not be impaired without the consent of such holder. In addition, subject to certain restrictions, the holders of a majority in principal amount of the outstanding notes are given the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or of exercising any trust or power conferred on the trustee.

The indenture provides that in the event an event of default has occurred and is continuing, the trustee will be required in the exercise of its powers to use the degree of care that a prudent person would use in the conduct of its own affairs. The trustee, however, may refuse to follow any direction that conflicts with law or the indenture or that the trustee determines is unduly prejudicial to the rights of any other holder or that would involve the trustee in personal liability. Prior to taking any action under the indenture, the trustee will be entitled to indemnification reasonably satisfactory to it against all losses and expenses caused by taking or not taking such action.

If a default occurs and is continuing and is known to the trustee, the trustee must transmit notice of the default to each holder within 90 days after it occurs. Except in the case of a default in the payment of principal (including the fundamental change purchase price) of or interest on any note or a default in the payment or delivery, as the case may be, of the consideration due upon conversion, the trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors and/or responsible officers of the trustee in good faith determines that the withholding of such notice is in the interests of the holders of the notes. In addition, we are required to deliver to the trustee, within 120 days after the end of each fiscal year, an officers' certificate, stating whether or not to the knowledge of the signers thereof we are in default in the performance and observance of any of the terms, provisions and conditions of the indenture (without regard to any period of grace or requirement of notice provided under the indenture) and, if we are in default, specifying all such defaults and the nature and the status thereof of which they may have knowledge. We also are required to deliver to the trustee, as soon as possible, and in any event within 30 days after we become aware of the occurrence of any default or event of default, an officers' certificate setting forth such defaults or events of default, as applicable, their status and what action we are taking or propose to take in respect thereof.

The following description replaces the description set forth under "Description of Debt Securities—Modification of the Indenture" in the accompanying prospectus in its entirety.

Subject to certain exceptions, the indenture or the notes may be amended, and compliance with any provisions of the indenture may be waived, with the consent of the holders of a majority of the principal amount of the notes then outstanding (including, in each case, without limitation, consents obtained in connection with a repurchase of, or tender or exchange offer for, notes). However, without the consent of each holder of a then outstanding note affected, no amendment may, among other things:

Without the consent of any holder of the notes, we and the trustee may amend the indenture or the notes:

Holders do not need to approve the particular form of any proposed amendment. It will be sufficient if such holders approve the substance of the proposed amendment. After an amendment under the indenture becomes effective, we are required to mail to the holders a notice briefly describing such amendment. However, the failure to give such notice to all the holders, or any defect in the notice, will not impair or affect the validity of the amendment.

We may satisfy and discharge our obligations under the indenture by delivering to the securities registrar for cancellation all outstanding notes or by depositing with the trustee or delivering to the holders, as applicable, after the notes have become due and payable, whether at the maturity date, any fundamental change purchase date, upon conversion or otherwise, cash or cash and shares of common stock, if any (solely to satisfy outstanding conversions, if applicable), sufficient to pay all of the outstanding notes and paying all other sums payable under the indenture by us. Such discharge is subject to terms contained in the indenture.

The provisions set forth under "Description of Debt Securities—Discharge, Defeasance and Covenant Defeasance" in the accompanying prospectus will not apply with respect to the notes.

Except as otherwise provided above, we will be responsible for making all calculations called for under the notes. These calculations include, but are not limited to, determinations of the last reported sale prices of our common stock, accrued interest payable on the notes and the conversion rate of the notes. We will make all these calculations in good faith and, absent manifest error, our calculations will be final and binding on holders of notes. We will provide a schedule of our calculations to each of the trustee and the conversion agent, and each of the trustee and the conversion agent is entitled to rely conclusively upon the accuracy of our calculations without independent verification. The trustee will forward our calculations to any holder of notes upon the request of that holder.

The indenture requires us to file with the trustee, within 15 days after we are required to file the same with the SEC, copies of the quarterly and annual reports and of the information, documents and other reports, if any, that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act, and to otherwise comply with Section 314(a) of the Trust Indenture Act. Any such report, information or document that we file with the SEC through the EDGAR system (or any successor thereto) will be deemed to be delivered to the trustee for the purposes of this covenant at the time of such filing through the EDGAR system (or such successor thereto).

Delivery of any such reports, information and documents to the trustee shall be for informational purposes only, and the trustee's receipt of such reports, information and documents shall not constitute constructive notice of any information contained therein or

determinable from information contained therein, including our compliance with any of our covenants hereunder.

The Bank of New York Mellon will be the trustee, security registrar, paying agent, conversion agent and bid solicitation agent. The Bank of New York Mellon, in each of its capacities, including without limitation as trustee, security registrar, paying agent and conversion agent, assumes no responsibility for the accuracy or completeness of the information concerning us or our affiliates or any other party contained in this document or the related documents or for any failure by us or any other party to disclose events that may have occurred and may affect the significance or accuracy of such information.

The indenture provides that it and the notes will be governed by, and construed in accordance with, the internal laws of the State of New York, including without limitation, sections 5-1401 and 5-1402 of the New York General Obligations Law and New York Civil Practice Laws and Rules 327(b).

The notes will be initially issued in the form of one or more registered notes in global form, without interest coupons, which we refer to as the global notes. Upon issuance, each of the global notes will be deposited with the trustee as custodian for DTC, which will serve as the initial securities depositary, and registered in the name of Cede & Co., as nominee of DTC.

Ownership of beneficial interests in a global note will be limited to persons who have accounts with DTC, which we refer to as DTC participants, or persons who hold interests through DTC participants. We expect that under procedures established by DTC:

Beneficial interests in global notes may not be exchanged for notes in physical, fully-registered certificated form except in the limited circumstances described below. We may not issue the notes in bearer form.

All interests in the global notes will be subject to the operations and procedures of DTC and, therefore, you must allow for sufficient time in order to comply with these procedures if you wish to exercise any of your rights with respect to the notes. We provide the following summary of those operations and procedures solely for the convenience of investors. The operations and procedures of DTC are controlled by that settlement system and may be changed at any time. Neither we nor the underwriters are responsible for those operations or procedures.

DTC was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants. DTC's participants include securities brokers and dealers, including the underwriters; banks and trust companies; clearing corporations and other organizations. Indirect access to DTC's system is also available to others such as banks, brokers, dealers and trust companies; these indirect participants clear through or maintain a custodial relationship with a DTC participant, either directly or indirectly. Investors who are not DTC participants may beneficially own securities held by or on behalf of DTC only through DTC participants or indirect participants in DTC.

So long as DTC's nominee is the registered owner of a global note, that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global note:

As a result, each investor who owns a beneficial interest in a global note must rely on the procedures of DTC to exercise any rights of a holder of notes under the indenture (and, if the investor is not a participant or an indirect participant in DTC, on the procedures of the DTC participant through which the investor owns its interest).

Payments of principal and interest with respect to the notes represented by a global note will be made by the trustee to DTC's nominee as the registered holder of the global note. Neither we nor the trustee will have any responsibility or liability for the payment of amounts to owners of beneficial interests in a global note, for any aspect of the records relating to or payments made on account of those interests by DTC, or for maintaining, supervising or reviewing any records of DTC relating to those interests.

Payments by participants and indirect participants in DTC to the owners of beneficial interests in a global note will be governed by standing instructions and customary industry practice and will be the responsibility of those participants or indirect participants and DTC.

Transfers between participants in DTC will be effected under DTC's procedures and will be settled in same-day funds.

Notwithstanding anything to the contrary under "Description of Debt Securities—Book-Entry Debt Securities" in the accompanying prospectus, notes in physical, fully-registered certificated form will be issued and delivered to each person that the depositary identifies as a beneficial owner of the related notes only if:

The following is a summary of additional U.S. federal income tax considerations applicable to "U.S. Holders" or "Non-U.S. Holders" (as such terms are defined below) relating to the purchase, ownership and disposition of the notes offered pursuant to this prospectus supplement. This summary is based upon the provisions of the Code, Treasury Regulations promulgated under the Code, administrative rulings and pronouncements and judicial decisions, all effective as of the date of this prospectus supplement. These authorities may be changed, perhaps with retroactive effect, so as to result in U.S. federal income tax consequences different from those set forth below.

This summary is limited to beneficial owners of notes that purchase the notes in this offering and that will hold the notes as capital assets within the meaning of Section 1221 of the Code. This summary does not address the tax considerations arising under other U.S. federal tax laws (such as estate and gift tax laws) or the laws of any foreign, state or local jurisdiction. In addition, this discussion does not address all of the tax considerations that may be applicable to U.S. Holders' particular circumstances or to U.S. Holders that may be subject to special tax rules under the U.S. federal income tax laws, such as, for example, financial institutions, insurance companies, tax-exempt organizations, brokers and dealers in securities or currencies, traders in securities that elect to use a mark-to-market method of tax accounting for their securities holdings, persons that will hold the notes as a position in a hedging transaction, straddle, conversion transaction or other risk reduction transaction, persons deemed to sell the notes under the constructive sale provisions of the Code, entities or arrangements treated as partnerships for U.S. federal income tax purposes and other pass-through entities, and investors in such entities.

This summary of additional U.S. federal income tax considerations is for general information only and is not tax advice. This summary is not binding on the IRS. We have not sought, and will not seek, any ruling from the IRS with respect to the statements made in this summary, and there can be no assurance that the IRS will not take a position contrary to these statements or that a contrary position taken by the IRS would not be sustained by a court. If you are considering purchasing notes, you are urged to consult your own tax advisors with respect to the application of the U.S. federal income tax laws to your particular situation, as well as any tax considerations arising under other federal tax laws, under the laws of any state, local, or foreign taxing jurisdiction or under any applicable income tax treaty.

The following is a summary of the general U.S. federal income tax consequences that will apply to you if you are a "U.S. Holder" of the notes. Certain consequences to "Non-U.S. Holders" of the notes are described under "—Consequences to Non-U.S. Holders of the Notes," below. For purposes of this discussion, a "U.S. Holder" means a beneficial owner of a note that is, for U.S. federal income tax purposes:

If an entity or arrangement classified as a partnership for U.S. federal income tax purposes holds notes, the U.S. federal income tax treatment of a partner in the partnership will generally depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. If you are an entity or arrangement treated as a partnership for U.S. federal income tax purposes (or if you are a partner in such a partnership), you are urged to consult your tax advisor regarding the tax consequences of the purchase, ownership and disposition of the notes to you.

Interest. Stated interest on the notes will generally be taxable to you as ordinary income at the time it is paid or accrued in accordance with your method of accounting for U.S. federal income tax purposes.

Sale, Exchange, Redemption or Repurchase of the Notes. You will generally recognize gain or loss upon the sale, exchange, redemption, repurchase or other taxable disposition of a note (other than a conversion into a combination of cash or common shares as further described below) equal to the difference (if any) between the amount realized on such disposition (other than amounts attributable to accrued but unpaid stated interest, which, if not previously taxed, will be taxable as ordinary interest income) and your tax basis in the note. Your tax basis in a note generally will be the purchase price paid therefor. Gain or loss recognized on the disposition of a note generally will be capital gain or loss, and will be long-term capital gain or loss if, at the time of such disposition, your holding period for the note is more than one year. Certain non-corporate U.S. holders (including individuals) are eligible for reduced rates of taxation in respect of long-term capital gain. The deductibility of capital losses is subject to certain limitations.

Conversion of the Notes for Cash. A conversion of a note in exchange solely for cash will be treated as a taxable sale or exchange of the note, as described above under "—Sale, Exchange, Redemption or Repurchase of the Notes."

Conversion of the Notes for Cash and Common Shares. The tax treatment of a conversion of a note into cash and common shares is uncertain.

If we satisfy the conversion obligation in part cash and part common shares, and the exchange is properly characterized as a recapitalization under Section 368(a)(1)(E) of the Code, you will recognize any gain realized in the conversion to the extent of the cash received, but will not recognize any loss realized in the conversion (except with respect to cash received in lieu of a fractional common share) . Your adjusted tax basis in the common shares received in the recapitalization will equal your tax basis in the corresponding note (reduced by any basis allocable to a fractional share), less the amount of cash received (excluding cash received in lieu of a fractional share), plus the amount of any taxable gain recognized on the conversion. Your holding period for the common shares received will include the holding period for the corresponding note surrendered in the conversion. Cash received in lieu of a fractional common share upon conversion of the notes will generally be treated as a payment in exchange for the fractional share. Accordingly, the receipt of cash in lieu of a fractional share generally will result in the recognition of capital gain or loss measured by the difference between the cash received for the fractional share and the portion of your tax basis allocable to the fractional share.

Alternatively, if the federal income tax treatment of the conversion is governed by Revenue Ruling 72-265 1972-1 C.B-1 222, it might instead be viewed as consisting of a nontaxable exchange of a portion of each note for common shares and a taxable exchange of the remaining portion of each note for cash , with either gain or loss recognized on the portion of the transaction treated as a taxable exchange. Your basis in the common shares received would equal a proportionate part (based on the fair market value of the common stock and the amount of cash you receive in the conversion) of the basis of the corresponding note surrendered in the conversion and the holding period of the common shares received would include the period during which you held such note.

Finally, because you will not have the unconditional right to demand shares in settlement of the conversion right, but delivery of such shares will be at our option alone, it is possible that the transaction might be viewed as a fully taxable exchange of the entire note for a combination of cash and common shares. If so, your tax basis in the common shares received generally will equal their fair market value on the date of receipt and your holding period for such common shares will begin the following day.

Holders are urged to consult their own advisors concerning the tax treatment to them if the notes are converted for a combination of our common shares and cash.

Constructive Distributions. The conversion rate of the notes is subject to adjustment under certain circumstances as described above in "Description of the Notes—Conversion Rights." Certain adjustments (or the absence of such adjustments) to the conversion rate of the notes that increase a noteholder's proportionate interest in our assets or earnings and profits may result in a taxable constructive distribution to the holder, whether or not the holder ever converts the notes. Any such taxable deemed distribution would not be eligible for a dividends-received deduction or the preferential tax rates applicable to dividends discussed below. A deemed distribution would arise, for example, if the conversion price were adjusted to compensate you for certain distributions of cash or property to our shareholders. In particular, adjustments made pursuant to the spin-off will result in a deemed distribution of an amount equal to the fair market value on the date of such deemed distribution of the additional number of shares into which your notes are convertible. In general, a change in conversion price that simply prevents the dilution of your interests upon a share split or other change in capital structure, if made under a bona fide, reasonable adjustment formula, would not be treated as a taxable deemed distribution. However, changes to the conversion rate pursuant to the spin-off will not qualify as a bona fide reasonable adjustment formula under applicable Treasury Regulations. Any taxable deemed distribution will be taxable as a dividend to the extent of the allocable current or accumulated earnings and profits, with any excess treated as a tax-free return of capital or as capital gains. You are urged to consult your own tax advisor with respect to the tax consequences of any adjustment (or the absence of any adjustment) to the conversion rate and any resulting deemed distribution.

Ownership and Disposition of Shares Received Upon Conversion. The tax consequences of owning and disposing of common shares received upon conversion of the notes are described in the prospectus under "U.S. Federal Income Tax Considerations—Taxation of Stockholders."

income includes, among other things, interest income not derived from the conduct of a nonpassive trade or business. Payments of interest on, and the recognition of capital gain with respect to, the notes are expected to constitute net investment income. A U.S. Holder that is an individual, estate or trust should consult its tax advisor regarding the applicability of the Medicare tax to its income and gains in respect of its investment in our notes.

Information Reporting and Backup Withholding. A U.S. Holder may be subject, under certain circumstances, to information reporting and/or backup withholding of tax (currently at a rate of 28%) with respect to payments of interest, and depending on the circumstances, the proceeds of a sale or other taxable disposition of a note (including a retirement or redemption).

Backup withholding may apply to a non-corporate U.S. Holder that (i) fails to furnish its taxpayer identification number, or TIN, (ii) furnishes an incorrect TIN, (iii) is notified by the IRS that it failed properly to report certain interest or dividends, or (iv) fails, under certain circumstances, to provide a certified statement, signed under penalty of perjury, that it is a U.S. person, that the TIN provided is correct, and that it has not been notified by the IRS that it is subject to backup withholding. The application for exemption is available by providing a properly completed IRS Form W-9 (or successor form). These requirements generally do not apply with respect to certain U.S. Holders, including corporations, tax-exempt organizations, qualified pension and profit sharing trusts, certain financial institutions and individual retirement accounts.

Backup withholding is not an additional tax. Any amount withheld from a payment to a U.S. Holder under the backup withholding rules will be allowed as a credit against such U.S. Holder's U.S. federal income tax liability and may entitle such U.S. Holder to a refund, provided that certain required information is timely furnished to the IRS. A U.S. Holder is urged to consult its own tax advisor regarding the application of information reporting and backup withholding in its particular circumstances, the availability of an exemption from backup withholding and the procedure for obtaining any such available exemption.

The following is a summary of the general U.S. federal income tax consequences that will apply to you if you are a "Non-U.S. Holder" of the notes. As used in this prospectus supplement, the term "Non-U.S. Holder" means a beneficial owner of a note (other than an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not a U.S. Holder.

If a partnership, including any entity or arrangement treated as a partnership for U.S. federal income tax purposes, is a holder of a note, the U.S. federal income tax treatment of a partner in such a partnership will generally depend on the status of the partner and the activities of the partnership. Partners in such a partnership are urged to consult their tax advisors as to the particular U.S. federal income tax consequences applicable to them of acquiring, holding or disposing of the notes.

Payments of Interest. Subject to the discussion of backup withholding below, if you are a Non-U.S. Holder, you will generally not be subject to U.S. federal income tax or the 30% U.S. federal withholding tax on interest paid on the notes so long as that interest is not effectively connected with your conduct of a trade or business within the United States, provided that:

The applicable Treasury Regulations provide alternative methods for satisfying the certification requirement described in this section. In addition, under these Treasury Regulations, special rules apply to pass-through entities and this certification requirement may also apply to beneficial owners of pass-through entities.

If you cannot satisfy the requirements described above, payments of interest will generally be subject to the 30% U.S. federal withholding tax, unless you provide the applicable withholding agent with a properly executed (1) IRS Form W-8BEN (or other applicable form) claiming an exemption from or reduction in withholding under an applicable income tax treaty or (2) IRS Form W-8ECI (or other applicable form) stating that interest paid on the notes is not subject to U.S. federal withholding tax because it is effectively connected with your conduct of a trade or business in the United States (as discussed below under "—Interest or Gain Effectively Connected with a U.S. Trade or Business").

Sale, Exchange, Redemption or Repurchase of the Notes. Subject to the discussion of backup withholding below, you will generally not be subject to U.S. federal income or withholding tax on any gain recognized on the sale or other taxable disposition of a note (including a retirement or redemption), unless:

If you are described in the first bullet point above, you will generally be subject to U.S. federal income tax at a rate of 30% on the amount by which your capital gains allocable to U.S. sources, including gain from such disposition, exceed any U.S.-source capital losses recognized in the same taxable year, except as otherwise required by an applicable income tax treaty. If you are described in the second bullet point, see "—Interest or Gain Effectively Connected with a U.S. Trade or Business," below. If the notes were to constitute a U.S. real property interest under FIRPTA, a sale or exchange of a note would generally be subject to the rules regarding taxation and withholding of U.S. federal income tax on sales of common shares under FIRPTA, as described in the prospectus under "U.S. Federal Income Tax Considerations—Taxation of Stockholders—Taxation of Foreign Stockholders—Dispositions of Our Stock." Although we believe that currently the notes do not constitute U.S. real property interests, and that we therefore would not currently be required to withhold under FIRPTA, there can be no assurance that the notes will not constitute U.S. real property interests depending on the facts in existence at the time of any redemption, repurchase, conversion or retirement of a note (as more fully described below), in which case we may be required to withhold 10% of any amounts payable on the redemption, repurchase, conversion or retirement by us of a note. Non-U.S. Holders are urged to consult their tax advisors as to whether the sale, redemption, repurchase or conversion of a note for our common shares is

exempt from U.S. federal income tax under FIRPTA, which may be exempt, if (i) our common shares are part of a class of shares that is regularly traded on an established securities market and such Non-U.S. Holders held notes that, on the date of their acquisition, had a fair market value equal to or less than the fair market value on that date of 5% of the common shares, (ii) we are a domestically-controlled REIT, or (iii) we are not a U.S. real property holding corporation. We will be a domestically-controlled REIT if at all times during a specified testing period we are a REIT and less than 50% in value of our shares is held directly or indirectly by non-U.S. persons. We believe that we currently are a domestically-controlled REIT, but because our common shares are publicly traded, there can be no assurance that we in fact are qualified or will continue to qualify as a domestically-controlled REIT. We will not be a U.S. real property holding corporation 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 are not currently a U.S. real property holding corporation, but we cannot assure you that we will not become a U.S. real property holding corporation in the future. If a sale, redemption, repurchase or conversion of a note for our common shares is exempt from U.S. federal income tax under FIRPTA, any amounts withheld from such payments to a Non-U.S. Holder may be refunded or credited against such Non-U.S. Holder's federal income tax liability, if any, if such Non-U.S. Holder files with the IRS, on a timely basis, the required IRS forms.

To the extent that the amount realized on any disposition of notes is attributable to accrued but unpaid interest, such amount generally will be treated in the same manner as payments of interest as described under the heading "—Payments of Interest" above.

Interest or Gain Effectively Connected with a U.S. Trade or Business. If you are engaged in a trade or business in the United States and interest on a note or gain recognized from the sale, exchange, redemption or other taxable disposition of a note is effectively connected with the conduct of that trade or business (and, if an income tax treaty applies, is attributable to a permanent establishment maintained by you in the United States), you will generally be subject to U.S. federal income tax (but not the 30% U.S. federal withholding tax if you provide an IRS Form W-8ECI with respect to interest, as described above) on that interest or gain on a net income basis in the same manner as if you were a U.S. person as defined under the Code. In addition, if you are a foreign corporation, you may be subject to a "branch profits tax" equal to 30% (or lower applicable income tax treaty rate) of your earnings and profits for the taxable year, subject to adjustments, that are effectively connected with your conduct of a trade or business in the United States. For this purpose, interest or gain effectively connected with your trade or business in the United States will be included in your earnings and profits.

Conversion of the Notes for Solely Cash or for a combination of Common Shares and Cash. To the extent you recognize any gain as a result of the receipt of cash in the conversion (including the receipt of cash in lieu of a fractional share upon conversion), such gain would be subject to the rules with respect to the sale or exchange of a note described above under "—Sale, Exchange, Redemption or Repurchase of the Notes."

Constructive Distributions. The conversion rate is subject to adjustment in certain circumstances. Any such adjustment could, in certain circumstances, give rise to a deemed distribution to Non-U.S. Holders of the notes. In particular, an adjustment made pursuant to the spin-off will result in a deemed distribution. See "—Consequences to U.S. Holders of the Notes—Constructive Distributions," above. In such case, the deemed distribution would be subject to the rules described in the prospectus under "U.S. Federal Income Tax Considerations—Taxation of Stockholders—Taxation of Foreign Stockholders." Because such deemed distributions will not give rise to any cash from which any applicable U.S. federal

withholding tax can be satisfied, the indenture provides that we may set off any withholding tax that we are required to collect with respect to any such deemed distribution against cash payments of interest or from cash or common shares otherwise deliverable to a holder upon a conversion of notes or a redemption or repurchase of a note. Until such time as judicial, legislative, or regulatory guidance becomes available that would, in our reasonable determination, permit us to treat such deemed distributions as other than deemed dividend distributions treated as ordinary income, we in general intend to withhold on such distributions at a 30% rate or whatever treaty rate is applicable to ordinary income dividends from REITs, to the extent such dividends are made out of our current or accumulated earnings and profits. A Non-U.S. Holder who is subject to withholding tax under such circumstances is urged to consult its own tax advisor as to whether it can obtain a refund for all or a portion of the withholding tax.

Information Reporting and Backup Withholding. Generally, information returns will be filed with the IRS in connection with payments of interest on the notes and proceeds from the sale or other taxable disposition (including a retirement or redemption) of the notes. Copies of applicable information returns reporting such payments and any withholding may also be made available to the tax authorities in the country in which you reside under the provisions of an applicable treaty or agreement.

You may be subject to backup withholding of tax (currently at a rate of 28%) on payments of interest and, depending on the circumstances, the proceeds of a sale or other taxable disposition (including a retirement or redemption) unless you comply with certain certification procedures to establish that you are not a U.S. person. The certification procedures required to claim an exemption from withholding of tax on interest described above generally will satisfy the certification requirements necessary to avoid backup withholding as well. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to you will be allowed as a credit against your U.S. federal income tax liability and may entitle you to a refund, provided that the required information is timely furnished to the IRS.

The company and the underwriters for the offering named below have entered into an underwriting agreement with respect to the notes. Subject to certain conditions, each underwriter has severally agreed to purchase the principal amount of notes indicated in the following table.

The underwriters are committed to take and pay for all of the notes being offered, if any are taken.

Notes sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus supplement. If all the notes are not sold at the initial public offering price, the underwriters may change the offering price and the other selling terms. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters' right to reject any order in whole or in part.

The underwriters will have the option to purchase within 30 days from the date of this prospectus supplement up to $60,000,000 principal amount of notes from us at the public offering price less the underwriting discount to cover over-allotments, if any.

We have agreed that, (i) for a period of 45 days from the date of this prospectus supplement, subject to certain exceptions, we will not, without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated, offer, sell, contract to sell, pledge, or otherwise dispose of, directly or indirectly, any shares of our common stock and (ii) for a period of 90 days from the date of this prospectus supplement, subject to certain exceptions, we will not, without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated, offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any securities convertible into, or exercisable, or exchangeable for, shares of our common stock, or, in each case, publicly announce any intention to do so. In addition, our officers and directors have agreed that, for a period of 45 days from the date of this prospectus supplement, subject to certain exceptions, they will not, without the prior written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated, offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, any shares of our common stock or any securities convertible into, or exercisable, or exchangeable for, shares of our common stock, or publicly announce any intention to do so. If (i) during the last 17 days of the 45-day restricted periods described above, 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 45-day restricted periods described above, we announce that we will release earnings results during the 16-day period beginning on the last day of the applicable 45-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 before the last day of the applicable 45-day 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 paragraph (a)(1) of Rule 139 under the Securities Act.

The notes are a new issue of securities with no established trading market. The company has been advised by the representatives of the underwriters that certain underwriters currently intend to make a market in the notes but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes.

In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters, as well as other purchases by the underwriters for their own accounts, may stabilize, maintain or otherwise affect the market price of the notes. As a result, the price of the notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

Unless otherwise indicated or the context requires otherwise, in this prospectus and any prospectus supplement hereto, references to "our company," "we," "us" and "our" mean Starwood Property Trust, Inc. and its consolidated subsidiaries.

We are a Maryland corporation that commenced operations in August 2009, upon the completion of our initial public offering. We are focused 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 collectively refer to commercial mortgage loans, other commercial real estate debt investments, CMBS, and other commercial real estate-related debt investments as our target assets. We also invest in residential mortgage-backed securities ("RMBS") and residential real estate assets acquired by us directly or indirectly in settlement of loans ("residential REO"), and may invest in distressed or non-performing loans, commercial properties subject to net leases and residential mortgage loans. As market conditions change over time, we may adjust our strategy to take advantage of changes in interest rates and credit spreads as well as economic and credit conditions.

Our objective is to provide attractive risk-adjusted global returns to our investors over the long term, primarily through dividends and secondarily through capital appreciation. We employ leverage, to the extent available, to fund the acquisition of our target assets and to increase potential returns to our stockholders. 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 organized as a holding company that conducts its business primarily through its various subsidiaries.

We are externally managed and advised by SPT Management, LLC (our "manager"), pursuant to the terms of a management agreement. Our manager is controlled by Barry Sternlicht, our Chairman and Chief Executive Officer. Our manager is an affiliate of Starwood Capital Group Global, L.P. ("Starwood Capital Group"), a privately-held private equity firm founded and controlled by Mr. Sternlicht.

We have elected to be taxed as a real estate investment trust ("REIT") for U.S. federal income tax purposes, commencing with our initial taxable year ended December 31, 2009. 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 (the "Investment Company Act").

Our corporate headquarters office is located at 591 West Putnam Avenue, Greenwich, Connecticut 06830, and our telephone number is (203) 422-8100.

Investing in our securities involves risks. You should carefully read and consider the risks described under the section entitled "Risk Factors" in our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q, which are incorporated by reference herein, as well as the other information contained in or incorporated by reference into this prospectus and in any applicable prospectus supplement, before making a decision to invest in our securities. Each of the risks described in these documents could materially and adversely affect our business, financial condition, results of operations and prospects, and could result in a partial or complete loss of your investment.

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:

In light of these risks and uncertainties, there can be no assurance 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.

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.

RATIOS OF EARNINGS TO FIXED CHARGES AND RATIOS OF EARNINGS TO COMBINED
FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

The following table sets forth (i) our ratios of earnings to fixed charges; and (ii) our ratios of earnings to combined fixed charges and preferred stock dividends for the periods shown. For this purpose, earnings consist of our net income (loss) from continuing operations plus our fixed charges and our distributed income of equity investees. Fixed charges consist of interest expense on all indebtedness. We have not issued any preferred stock as of the date of this prospectus, and therefore there are no preferred stock dividends included in our calculation of ratios of earnings to combined fixed charges and preferred stock dividends.

Our senior debt securities will be issued under a senior indenture, as amended or supplemented from time to time, between the Company and The Bank of New York Mellon as Trustee (the "indenture").

The following description is a summary of the material provisions of the indenture including references to the applicable section of the indenture. It does not restate the indenture in its entirety. We urge you to read the indenture because it, and not this description, defines the rights of holders of debt securities. Except as otherwise defined herein, terms used in this description but not otherwise defined herein are used as defined in the indenture. When we refer to "Starwood," "we," "our," "us," and "the Company" in this section, we are referring to Starwood Property Trust, Inc. excluding its subsidiaries, unless the context otherwise requires or as otherwise expressly stated herein.

The indenture is incorporated by reference as an exhibit to the Registration Statement of which this prospectus is a part. The indenture is available for inspection at the corporate trust offices of the Trustee at The Bank of New York Mellon, 101 Barclay Street, Floor 8W, New York, New York 10286. The indenture is subject to, and is governed by, the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). All section references appearing in this description are to sections of the indenture.

Our debt securities will be direct, unsecured obligations. The debt securities issued under the indenture are not limited as to aggregate principal amount and may be issued in one or more series. The principal amount and series will be established from time to time in or pursuant to authority granted by a resolution of our board of directors. The principal amount and series also may be established in one or more indentures supplemental to the indenture. All debt securities of one series need not be issued at the same time (section 301 of the indenture). Unless otherwise provided, a series may be reopened for issuances of additional debt securities of such series without the consent of the holders of the debt securities of such series (section 301 of the indenture). The Trustee may resign or be removed with respect to one or more series of debt securities issued under the indenture, and a successor Trustee may be appointed to act with respect to such series.

Reference is made to each prospectus supplement for the specific terms of the series of debt securities being offered thereby, including:

(2) the aggregate principal amount of such debt securities and any limit on such aggregate principal amount;

(3) the percentage of the principal amount at which such debt securities will be issued and, if other than the principal amount thereof, the portion of the principal amount thereof payable upon declaration of acceleration of the maturity of such debt securities, or (if applicable) the portion of the principal amount of such debt securities which is convertible into shares of our common stock or other equity securities, or the method by which any such portion shall be determined;

(5) the date(s), or the method for determining the date(s), on which the principal of such debt securities will be payable;

(6) the rate(s) (which may be fixed or variable) at which such debt securities will bear interest, if any, or the method by which such rate(s) shall be determined;

(7) the date(s), or the method for determining the date(s), from which interest, if any, will accrue;

(9) the record date(s) for an interest payment, or the method by which such record date(s) shall be determined (the record date for an interest payment is the date on which a Person must be a holder in order to receive the interest payment);

(11) the basis upon which any interest shall be calculated if other than that of a 360-day year consisting of twelve 30-day months;

(13) the period(s) within which, the price(s) at which, and the terms and conditions upon which such debt securities may be redeemed at our option, as a whole or in part, if we are to have the option to redeem such debt securities;

(14) our obligation, if any, to redeem, repay or purchase such debt securities pursuant to any sinking fund or analogous provision or at the option of a holder thereof, and the period(s) within which, the price(s) at which, and the terms and conditions upon which we are obligated, if at all, to redeem, repay or purchase such debt securities, as a whole or in part, pursuant to any sinking fund or analogous provision or at the option of a holder thereof;

(15) if other than U.S. dollars, the currency or currencies in which such debt securities are denominated and payable, which may be a foreign currency or units of two or more foreign currencies or a composite currency or currencies, and the terms and conditions relating thereto;

(16) whether the amount of payments of principal of (and premium, if any) or interest, if any, on such debt securities may be determined with reference to an index, formula or other method and the manner in which such amounts shall be determined (the index, formula or method may, but need not be, based on a currency, currencies, currency unit or units or composite currency or currencies);

(17) any additions to, modifications of or deletions from the terms of such debt securities with respect to the Events of Default or covenants set forth in the indenture;

(18) whether such debt securities will be issued in certificated or book-entry form;

(19) whether such debt securities will be in registered or bearer form or both and, if and to the extent in registered form, the denominations thereof if other than $1,000 and any integral multiple thereof and, if and to the extent in bearer form, the denominations thereof and terms and conditions relating thereto;

(20) the applicability, if any, of the defeasance and covenant defeasance provisions of the indenture;

(21) the terms, if any, upon which such debt securities may be convertible into shares of our common stock or other equity securities (and the class thereof) and the terms and conditions upon

which such conversion will be effected, including, without limitation, the initial conversion price or rate, the conversion period, any adjustment of the applicable conversion price and any requirements relative to the reservation of such shares for purposes of conversion;

(22) whether and under what circumstances we will pay Additional Amounts on such debt securities in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem such debt securities in lieu of making such payment;

(24) provisions, if any, granting special rights to holders upon the occurrence of such events as may be specified;

(25) if securities are to be issued upon the exercise of warrants, the time, manner and place for authentication and delivery; and

(26) any other terms of such debt securities not inconsistent with the provisions of the indenture.

The debt securities may provide for the payment of less than the entire principal amount upon declaration of acceleration of the maturity of the debt securities. Such debt securities are known as "Original Issue Discount Securities." Any material U.S. federal income tax, accounting and other considerations applicable to Original Issue Discount Securities will be described in the applicable prospectus supplement.

The indenture does not contain any provision that would limit our ability to incur indebtedness or that would afford holders of debt securities protection in a highly leveraged or similar action involving Starwood or in the event of a change of control of Starwood. However, certain restrictions on ownership and transfer of our common stock and other equity securities designed to preserve our status as a REIT may act to prevent or hinder a change of control. See "Description of Capital Stock." Reference is made to the applicable prospectus supplement for information with respect to any deletion from, modification of or addition to the Events of Default or our covenants that are described below, including any addition of a covenant or other provision providing event risk or similar protection.

Unless otherwise described in the applicable prospectus supplement, the debt securities of any series will be issued in denominations of $1,000 and integral multiples thereof, other than bearer securities issued in global form (section 302 of the indenture).

Unless otherwise specified in the applicable prospectus supplement, principal, premium, if any, and interest payments on any series of debt securities will be made at the corporate trust office of the Trustee as follows: The Bank of New York Mellon, 101 Barclay Street, Floor 8W, New York, New York 10286. However, we may elect to pay interest by check mailed to the address of the holder as it appears in the register for debt securities of such series or by wire transfer of funds to the holder at an account maintained within the United States (sections 301, 305, 306, 307 and 1002 of the indenture).

Any interest with respect to a debt security that is not punctually paid or duly provided for on the date the interest is due and payable will cease to be payable thereafter to the holder on the applicable record date. The interest may be paid to the holder at the close of business on a special record date fixed by the Trustee for the payment of the interest. Notice of such payment must be given to the holder of such debt security not less than 10 days prior to the special record date. Such interest may also be paid at any time in any other lawful manner, all as more completely described in the indenture (section 307 of the indenture).

Subject to certain limitations applicable to debt securities issued in book-entry form, the debt securities of any series will be exchangeable for other debt securities of the same series and of a like

aggregate principal amount and tenor of different authorized denominations upon surrender of such debt securities at the corporate trust office of the Trustee. In addition, subject to certain limitations applicable to debt securities issued in book-entry form, the debt securities of any series may be surrendered for conversion or registration of transfer thereof at the corporate trust office of the Trustee. Every debt security surrendered for conversion, registration of transfer or exchange must be duly endorsed or accompanied by a written instrument of transfer. No service charge will be incurred for any registration of transfer or exchange of any debt securities, but we may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith (section 305 of the indenture). If the applicable prospectus supplement refers to any transfer agent (in addition to the Trustee) that we initially designated with respect to any series of debt securities, we may at any time rescind the designation of any such transfer agent or approve a change in the location at which any such transfer agent acts; however, we will be required to maintain a transfer agent in each place where principal, premium, if any, and interest payments on debt securities of such series are payable. We may designate additional transfer agents with respect to any series of debt securities at any time (section 1002 of the indenture).

The indenture provides that we may consolidate with, or sell, lease or convey all or substantially all of our assets to, or merge with or into, any other Person, provided that:

(1) we are the continuing Person, or the successor Person shall be organized and existing under the laws of the United States or a state thereof and shall expressly assumes payment of the principal of (and premium, if any) and interest and all Additional Amounts, if any, on, all of the outstanding debt securities and the due and punctual performance and observance of all of the covenants and conditions contained in the indenture by supplemental indenture satisfactory to the Trustee;

(2) immediately after giving effect to such transaction and treating any indebtedness which becomes our or our subsidiaries' obligation as a result thereof as having been incurred by us or our subsidiaries at the time of such transaction, no Event of Default under the indenture, and no event which, after notice or the lapse of time, or both, would become such an Event of Default, occurs and is continuing; and

(3) an officer's certificate and legal opinion confirming the satisfaction of the conditions are delivered to the Trustee (sections 801 and 803 of the indenture).

Existence. Except as permitted under the provisions of the indenture described under the caption "Merger, Consolidation or Sale," we must preserve and keep in full force and effect our corporate existence, rights (charter and statutory) and franchises. We will not be required to preserve any right or franchise if we determine that the preservation of that right or franchise is no longer desirable in the conduct of our business and that the loss thereof is not disadvantageous in any material respect to the holders of the senior debt securities (section 1004 of the indenture).

Maintenance of Properties. All of our properties that are used or useful in the conduct of our business or the business of our subsidiaries must be maintained and kept in good condition, repair and working order and supplied with all necessary equipment. We also are required to make all necessary repairs, renewals, replacements, betterments and improvements to our properties. We must do these things as necessary in our judgment to conduct the business carried on in connection therewith in a proper and advantageous manner at all times. However, we and our subsidiaries will not be prevented from selling or otherwise disposing of properties for value in the ordinary course of business (section 1005 of the indenture).

Payment of Taxes and Other Claims. We must pay or discharge, or cause to be paid or discharged, before the same become delinquent:

(1) all taxes, assessments and governmental charges levied or imposed upon us or any of our subsidiaries or upon our or any of our subsidiaries' income, profits or property; and

(2) all lawful claims for labor, materials and supplies that, if unpaid, might by law become a lien upon our property or the property of any of our subsidiaries.

However, we will not be required to pay or discharge, or cause to be paid or discharged, any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings (section 1006 of the indenture).

Provision of Financial Information. We will be required to file with the trustee, within 15 days after we file the same with the SEC, copies of the annual and other reports which we are required to file with the SEC pursuant to Section 13 or 15(d) of Securities Exchange Act of 1934, as amended (the "Exchange Act"). If we are not so required to file such reports to the SEC under said Sections, then we will be required to file with the Trustee and the SEC, in accordance with the rules and regulations prescribed by the SEC, such of the supplementary and periodic reports which may be required pursuant to Section 13 of the Exchange Act in respect of a security listed and registered on a national securities exchange as may be prescribed in such rules and regulations. Any documents filed by us with the SEC via the SEC's EDGAR system will be deemed filed with the Trustee as of the time such documents are filed via the SEC's EDGAR system.

The indenture provides that the following events are "Events of Default" with respect to any series of debt securities issued thereunder:

(1) default for 30 days in the payment of any installment of interest, Additional Amounts or coupons on any debt security of such series;

(2) default in the payment of the principal of (or premium, if any, on) any debt security of such series at the time such payment becomes due and payable;

(3) default in making any sinking fund payment as required for any debt security of such series;

(4) default in the performance, or breach, of any other covenant or warranty contained in the indenture continued for 60 days after written notice as provided in the indenture; however, default in the performance, or breach, of a covenant or warranty added to the indenture solely for the benefit of a series of debt securities issued thereunder other than such series is not an Event of Default;

(5) default under any bond, debenture, note or other evidence of indebtedness of the Company or under any mortgage, indenture or other instrument of the Company under which there may be issued or by which there may be secured or evidenced any indebtedness of the Company (or by any subsidiary, the repayment of which the Company has guaranteed or for which the Company is directly responsible or liable as obligor or guarantor), which results in the acceleration of indebtedness in an aggregate principal amount exceeding $75,000,000, but only if such indebtedness is not discharged or such acceleration is not rescinded or annulled as provided in the indenture;

(6) certain events of bankruptcy, insolvency or reorganization, or court appointment of a receiver, liquidator or trustee, of the Company or of any significant subsidiary of the Company as defined in Regulation S-X promulgated under the Securities Act of 1933, as amended (the "Securities Act") or of the respective property of either; and

(7) any other Event of Default provided with respect to that series of debt securities (section 501 of the indenture).

If an Event of Default occurs under the indenture with respect to Outstanding debt securities of any series issued thereunder and is continuing, then the Trustee or the holders of not less than 25% in principal amount of the Outstanding debt securities of that series may declare the principal amount of all of the debt securities of that series to be due and payable immediately by written notice to us. If the holders give notice to us, they must also give notice to the Trustee. If the debt securities are Original Issue Discount Securities or Indexed Securities, the amount declared to be due and payable will be such portion of the principal amount as specified in the terms thereof. However, at any time after a declaration of acceleration with respect to debt securities of such series (or of all debt securities then Outstanding under the indenture, as the case may be) has been made, the holders of a majority in principal amount of the debt securities of such series or of each series of debt securities then Outstanding under the indenture, as the case may be, may rescind and annul such declaration and its consequences if:

(1) we have deposited with the Trustee all required payments of the principal of (and premium, if any) and interest and Additional Amounts payable on the debt securities of such series or of all debt securities then Outstanding under the indenture, as the case may be, plus certain fees, expenses, disbursements and advances of the Trustee; and

(2) all Events of Default have been cured or waived as provided in the indenture (except for the nonpayment of accelerated principal (or specified portion thereof) with respect to debt securities of such series or of all debt securities then Outstanding under the indenture) (section 502 of the indenture).

The indenture also provides that the holders of a majority in principal amount of the debt securities of any series or of each series of debt securities then Outstanding under the indenture may waive any past default with respect to such series and its consequences.

The indenture provides that the Trustee is required to give notice to the holders of debt securities issued thereunder within 90 days of a default under the indenture. However, the Trustee may withhold notice of any default to the holders of any such series of debt securities if certain officers of the Trustee consider such withholding to be in the interest of the holders. The Trustee may not withhold notice with respect to a default in the payment of the principal of (or premium, if any) or interest on any debt security or in the payment of any sinking installment in respect of any debt security (section 601 of the indenture).

The indenture provides that no holder of debt securities of any series issued thereunder may institute any proceeding, judicial or otherwise, with respect to the indenture or for any remedy thereunder. However, a holder of debt securities may institute a proceeding if the Trustee fails to act for 60 days after it has received a written request to institute proceedings in respect of an Event of Default from the holders of not less than 25% in principal amount of the Outstanding debt securities of such series, as well as an offer of indemnity reasonably satisfactory to it (section 507 of the indenture). However, this provision will not prevent any holder of debt securities from instituting suit for the enforcement of payment of the principal of (and premium, if any) and interest on the debt securities held by that holder at the respective due dates thereof (section 508 of the indenture).

Subject to provisions in the indenture relating to its duties in case of default and unless holders of any series of debt securities then Outstanding under the indenture have offered security or indemnity reasonably satisfactory to the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the indenture at the request or direction of the holders (section 602 of the indenture). The holders of a majority in principal amount of the Outstanding debt securities of any series (or of each series of debt securities then Outstanding under the indenture, as the case may be) shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee. They also have the right to direct the time, method and place of exercising any trust or power conferred upon the Trustee. However, the Trustee may refuse to follow any direction which is in conflict with the indenture or any law which may involve the Trustee in personal liability or which may be unduly prejudicial to the holders of debt securities of such series not joining therein (section 512 of the indenture).

Within 120 days after the close of each fiscal year, we must deliver to the Trustee a certificate signed by one of several specified officers. The certificate must state whether such officer has knowledge of any default under the indenture and, if so, specify each such default and the nature and status thereof (section 1007 of the indenture).

Modifications and amendments to the indenture may be made only with the consent of the holders of a majority in principal amount of all Outstanding debt securities issued thereunder which are affected by such modification or amendment. However, unless the consent of the holder of each affected debt security is obtained, no modification or amendment may:

The indenture provides that the holders of a majority in principal amount of Outstanding debt securities issued thereunder have the right to waive our compliance with certain covenants in the indenture, including those described in the section of this prospectus captioned "Material Covenants" (section 902 of the indenture).

Starwood and the Trustee may modify and amend the indenture without the consent of any holder of debt securities issued thereunder for any of the following purposes:

The indenture provides that in determining whether the holders of the requisite principal amount of Outstanding debt securities of a series issued thereunder have given any request, demand, authorization, direction, notice, consent or waiver thereunder or whether a quorum is present at a meeting of holders of such debt securities:

The indenture contains provisions for convening meetings of the holders of an issued series of debt securities (section 1501 of the indenture). The Trustee may call a meeting at any time. Starwood or the holders of at least 10% in principal amount of the Outstanding debt securities of such series may also call a meeting upon request. Notice of a meeting must be given as provided in the indenture (section 1502 of the indenture). Except for any consent that must be given by the holder of each debt security affected by certain modifications and amendments of the indenture, any resolution presented at a meeting or adjourned meeting duly reconvened at which a quorum is present may be adopted by the affirmative vote of the holders of a majority in principal amount of the Outstanding debt securities of that series. However, except as referred to above, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that may be made, given or taken by the holders of a specified percentage which is less than a majority in principal amount of the Outstanding debt securities of a series may be adopted at a meeting or adjourned meeting duly reconvened at which a quorum is present by the affirmative vote of the holders of such specified percentage in principal amount of the Outstanding debt securities of that series. Any resolution passed or decision taken at any duly held meeting of holders of debt securities of any series will be binding on all holders of debt securities of that series. The quorum at any meeting called to adopt a resolution, and at any reconvened meeting, will be the persons holding or representing a majority in principal amount of the Outstanding debt securities of a series.

However, if any action is to be taken at such meeting with respect to a consent or waiver which may be given by the holders of not less than a specified percentage in principal amount of the Outstanding debt securities of a series, the persons holding or representing such specified percentage in principal amount of the Outstanding debt securities of such series will constitute a quorum (section 1504 of the indenture).

Notwithstanding the provisions described above, if any action is to be taken at a meeting of holders of debt securities of any series with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that the indenture expressly provides may be made, given or taken by the holders of a specified percentage in principal amount of all Outstanding debt securities affected thereby, or of the holders of such series and one or more additional series:

(2) the principal amount of the Outstanding debt securities of such series that vote in favor of such request, demand, authorization, direction, notice, consent, waiver or other action shall be taken into account in determining whether such request, demand, authorization, direction, notice, consent, waiver or other action has been made, given or taken under the indenture (section 1504 of the indenture).

We may discharge certain obligations to holders of any series of debt securities that have not already been delivered to the Trustee for cancellation and that either have become due and payable or will become due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the Trustee, in trust, funds in an amount sufficient to pay the entire indebtedness on such debt securities in respect of principal, premium, if any, and interest to the date of such deposit if such debt securities have become due and payable or to the date specified in such debt securities as the fixed date on which the payment of principal and interest on such debt securities is due and payable or the date fixed for redemption of such debt securities, as the case may be (section 401 of the indenture). Funds shall be deposited in such currency or currencies, currency unit(s) or composite currency or currencies in which such debt securities are payable.

The indenture provides that, if the provisions of Article Fourteen thereof (relating to defeasance and covenant defeasance) are made applicable to the debt securities of or within any series issued thereunder, we may elect either:

(1) to defease and be discharged from any and all obligations with respect to such debt securities. However, we will not be discharged from the obligation to pay Additional Amounts, if any, upon the occurrence of certain events of tax, assessment or governmental charge with respect to payments on such debt securities. In addition, we will not be discharged from the obligations to register the transfer or exchange of such debt securities, to replace temporary or mutilated, destroyed, lost or stolen debt securities, to maintain an office or agency in respect of such debt securities and to hold moneys for payment in trust ("defeasance") (section 1402 of the indenture); or

(2) to be released from our obligations relating to (a) sections 1004 to 1006, inclusive, of the indenture (being the restrictions described under the caption "Material Covenants") and, if provided under the indenture, our obligations with respect to any other covenant contained in the indenture, and any omission to comply with such obligations shall not constitute a default or an Event of Default with respect to such debt securities ("covenant defeasance") (section 1403 of the indenture).

Defeasance or covenant defeasance will occur upon our irrevocable deposit with the Trustee, in trust, of an amount sufficient to pay the principal of (and premium, if any) and interest on such debt securities, and any mandatory sinking fund or analogous payments, on their scheduled due dates. The amount deposited will be in Government Obligations (as defined below) or such currency or currencies,

currency unit(s) or composite currency or currencies in which such debt securities are payable at maturity, or both.

Such a trust may be established only if, among other things, we have delivered to the Trustee an opinion of counsel (as specified in the indenture) to the effect that the holders of such debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. In the case of defeasance, the opinion of counsel must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable United States federal income tax law occurring after the date of the indenture (section 1404 of the indenture).

(1) direct obligations of the United States of America or the government which issued the foreign currency in which the debt securities of a particular series are payable, and for which the full faith and credit of the applicable government is pledged; or

(2) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of the United States of America or the other government or governments in the confederation which issued the foreign currency in which the debt securities of such series are payable. The payment of these obligations must be unconditionally guaranteed as a full faith and credit obligation by the United States of America or such other government or governments, and the obligations may not be callable or redeemable at the option of the issuer or issuers thereof. Such obligations also include a depository receipt issued by a bank or trust company as custodian with respect to any such Government Obligation or a specific payment of interest on or principal of or other amount with respect to any such Government Obligation held by such custodian for the account of the holder of a depository receipt, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depository receipt from any amount received by the custodian in respect of the Government Obligation or the specific payment of interest on or principal of or other amount with respect to the Government Obligation evidenced by such depository receipt (section 101 of the indenture).

Unless otherwise provided in the applicable prospectus supplement, if after we have deposited funds and/or Government Obligations to effect defeasance or covenant defeasance with respect to debt securities of any series:

(1) the holder of a debt security of such series is entitled to, and does, elect under the indenture or the terms of such debt security to receive payment in a currency, currency unit or composite currency other than that in which such deposit has been made in respect of such debt security, or

(2) a Conversion Event (as defined below) occurs in respect of the currency, currency unit or composite currency in which such deposit has been made,

the indebtedness represented by such debt security shall be deemed to have been, and will be, fully discharged and satisfied through the payment of the principal of (and premium, if any) and interest on such debt security as they become due out of the proceeds yielded by converting the amount deposited in respect of such debt security into the currency, currency unit or composite currency in which such debt security becomes payable as a result of such election or such cessation of usage based on the applicable market exchange rate (section 1405 of the indenture).

(1) a currency, currency unit or composite currency both by the government of the country which issued such currency and for the settlement of actions by a central bank or other public institution of or within the international banking community; or

(2) any currency unit or composite currency for the purposes for which it was established (section 101 of the indenture).

Unless otherwise described in the applicable prospectus supplement, all payments of principal of (and premium, if any) and interest on any debt security that is payable in a foreign currency that ceases to be used by its government of issuance shall be made in U.S. dollars.

In the event we effect covenant defeasance with respect to any debt securities and such debt securities are declared due and payable because of the occurrence of any Event of Default, other than:

(1) the Event of Default described in clause (4) under "Events of Default, Notice and Waiver" or

(2) the Event of Default described in clause (7) under "Events of Default, Notice and Waiver" with respect to any other covenant as to which there has been covenant defeasance,

the amount in such currency, currency unit or composite currency in which such debt securities are payable, and Government Obligations on deposit with the Trustee, will be sufficient to pay amounts due on such debt securities at the fixed date on which they become due and payable but may not be sufficient to pay amounts due on such debt securities at the time of the acceleration resulting from such Event of Default. In any such event, we would remain liable to make payment of such amounts due at the time of acceleration.

The applicable prospectus supplement may further describe the provisions, if any, permitting such defeasance or covenant defeasance, including any modifications to the provisions described above, with respect to the debt securities of or within a particular series.

The debt securities will constitute our senior unsecured obligations and will rank equal in right of payment with our existing and future senior unsecured obligations. The debt securities will rank senior in right of payment to any future indebtedness we may have that is expressly subordinated in right of payment to the debt securities. The debt securities will rank effectively junior in right of payment to any of our existing and future secured indebtedness, to the extent of the value of the assets securing such indebtedness, and will rank structurally junior to all existing and future indebtedness (including trade payables) and preferred equity of our subsidiaries as well as to any of our existing or future indebtedness that may be guaranteed by any of our subsidiaries (to the extent of any such guarantee). As of September 30, 2012, our total consolidated indebtedness (excluding trade payables and unfunded commitments) was $1.4 billion, $158.8 million of which was secured indebtedness of ours and $1.2 billion of which was indebtedness of our subsidiaries to third parties (excluding trade payables).

The following provisions will apply to debt securities that will be convertible into our common stock or other equity securities ("Convertible debt securities") unless otherwise described in the prospectus supplement for such Convertible debt securities.

Our board of directors will determine the terms and conditions of any Convertible debt securities, if any, issued pursuant to the indenture ("Senior Convertible debt securities"). Such terms and conditions may include whether the Senior Convertible debt securities are convertible into our shares

of common or preferred stock (including, without limitation, the initial conversion price or rate, the conversion period, any adjustment of the applicable conversion price and any requirements relative to the reservation of such shares for purposes of conversion) (section 301 of the indenture).

The adjustment provisions for debt securities convertible into our equity securities other than shares of common stock will be determined at the time of issuance of such debt securities and will be set forth in the applicable prospectus supplement.

Reference is made to the section captioned "Description of Common Stock" for a general description of securities to be acquired upon the conversion of Convertible debt securities that are convertible into our common stock, including a description of certain restrictions on the ownership of the shares of common stock.

The Bank of New York Mellon serves as Trustee for our debt securities pursuant to the indenture.

Set forth below are defined terms used in the indenture. Reference is made to the indenture for a full disclosure of all such terms, as well as any other capitalized terms used herein for which no definition is provided.

"Additional Amounts" means any additional amounts which are required by a debt security or by or pursuant to a resolution of our board of directors, under circumstances specified therein, to be paid by us in respect of certain taxes imposed on certain holders and which are owing to such holders.

"Affiliate" of any Person means any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such Person. Control means the power to direct the management and policies of a Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise.

"Holder" means the Person in whose name a debt security is registered in the register for each series of debt securities.

"Indexed Security" means a debt security for which the principal amount payable on the date specified in such debt security as the fixed date on which the principal of such security is due and payable may be more or less than the principal face amount thereof at original issuance.

"Outstanding," when used with respect to debt securities, means, as of the date of determination, all debt securities theretofore authenticated and delivered under the indenture, except:

(1) debt securities theretofore canceled by the Trustee or delivered to the Trustee for cancellation;

(2) debt securities, or portions thereof, for whose payment or redemption or repayment at the option of the holder money in the necessary amount has been deposited with the Trustee or any paying agent (other than by us) in trust or set aside and segregated in trust by us (if we shall act as our own paying agent) for the holders of such debt securities and any coupons appertaining thereto, provided that, if such debt securities are to be redeemed, notice of such redemption has been duly given pursuant to the indenture or provision therefor satisfactory to the Trustee has been made;

(3) debt securities, except to the extent provided in sections 1402 and 1403 of the indenture, with respect to which we have effected defeasance and/or covenant defeasance;

(4) debt securities which have been paid pursuant to section 306 or in exchange for or in lieu of which other debt securities have been authenticated and delivered pursuant to the indenture, other than any such debt securities in respect of which there shall have been presented to the Trustee proof satisfactory to it that such debt securities are held by a bona fide purchaser in whose hands such debt securities are our valid obligations; and

(5) debt securities converted into shares of common stock or preferred stock in accordance with or as contemplated by the indenture, if the terms of such debt securities provide for convertibility pursuant to section 301;

provided, however, that in determining whether the holders of the requisite principal amount of the Outstanding securities have given any request, demand, authorization, direction, notice, consent of waiver hereunder or are present at a meeting of holders for quorum purposes, and for the purpose of making the calculations required by section 313 of the Trust Indenture Act:

(1) the principal amount of an Original Issue Discount Security that may be counted in making such determination or calculation and that shall be deemed to be Outstanding for such purpose shall be equal to the amount of principal that would be (or shall have been declared to be) due and payable, at the time of such determination, upon a declaration of acceleration of the maturity thereof;

(2) the principal amount of any debt security denominated in a foreign currency that may be counted in making such determination or calculation and that shall be deemed Outstanding for such purpose shall be equal to the U.S. dollar equivalent, determined pursuant to section 301 as of the date such debt security is originally issued by us, of the principal amount (or, in the case of an Original Issue Discount Security, the U.S. dollar equivalent as of such date of original issuance of the amount determined as provided in clause (1) above) of such debt security;

(3) the principal amount of any Indexed Security that may be counted in making such determination or calculation and that shall be deemed Outstanding for such purpose shall be equal to the principal face amount of such Indexed Security at original issuance, unless otherwise provided with respect to such Indexed Security pursuant to section 301; and

(4) debt securities owned by us or any other obligor upon the debt securities or any Affiliate of ours or of such other obligor shall be disregarded and deemed not to be Outstanding, except that, in determining whether the Trustee shall be protected in making such calculation or in relying upon any such request, demand, authorization, direction, notice, consent or waiver, only debt securities which the Trustee knows to be so owned shall be so disregarded. Debt securities so owned which have been pledged in good faith may be regarded as Outstanding if the pledgee establishes to the satisfaction of the Trustee the pledgee's right so to act with respect to any such debt securities and that the pledgee is not us or any other obligor upon the debt securities or any Affiliate of ours or of such other obligor.

"Person" means any individual, corporation, partnership, joint venture, association, joint-stock company, trust, unincorporated organization or government or any agency or political subdivision thereof.

"Subsidiary" means an entity a majority of the outstanding voting stock of which is owned, directly or indirectly, by us or by one or more of our other subsidiaries. For purposes of this definition, "voting stock" means stock having voting power for the election of directors, whether at all times or only so long as no senior class of stock has such voting power by reason of any contingency.

The indenture and the debt securities will be governed by, and construed in accordance with, the laws of the State of New York.

We may issue debt securities of a series in whole or in part in the form of one or more global securities. We will deposit such global securities with, or on behalf of, a depository identified in the applicable prospectus supplement. We may issue global securities in either registered or bearer form and in either temporary or permanent form. Unless we specify otherwise in the applicable prospectus

supplement, debt securities that are represented by a global security will be issued in denominations of $1,000 or any integral multiple thereof, other than bearer securities in global form, and will be issued in registered form only, without coupons. We will make payments of principal of, premium, if any, and interest on debt securities represented by a global security to the Trustee under the indenture, which will then forward such payments to the depository.

We anticipate that any global securities will be deposited with, or on behalf of, The Depository Trust Company, New York, New York ("DTC"), and that such global securities will be registered in the name of Cede & Co., DTC's nominee. We further anticipate that the following provisions will apply to the depository arrangements with respect to any such global securities. We will describe any additional or differing terms of the depository arrangements in the applicable prospectus supplement relating to a particular series of debt securities issued in the form of global securities.

So long as DTC or its nominee is the registered owner of a global security, DTC or its nominee, as the case may be, will be considered the sole holder of the debt securities represented by such global security for all purposes under the indenture. Except as described below, owners of beneficial interests in a global security:

(1) will not be entitled to have debt securities represented by such global security registered in their names;

(2) will not receive or be entitled to receive physical delivery of debt securities in certificated form; and

The laws of some states require that certain purchasers of securities take physical delivery of such securities in certificated form; accordingly, such laws may limit the transferability of beneficial interests in a global security.

Unless we specify otherwise in the applicable prospectus supplement, each global security representing book-entry notes will be exchangeable for certificated notes only if:

(1) DTC notifies us that it is unwilling or unable to continue as depository or DTC ceases to be a clearing agency registered under the Exchange Act (if so required by applicable law or regulation) and, in either case, a successor depository is not appointed by us within 90 days after we receive such notice or become aware of such unwillingness, inability or ineligibility;

(2) we, in our sole discretion, determine that the global securities shall be exchangeable for certificated notes; or

(3) there shall have occurred and be continuing an event of default under the indenture with respect to the notes.

Upon any such exchange, owners of a beneficial interest in the global security or securities representing book-entry notes will be entitled to physical delivery of individual debt securities in certificated form of like tenor and rank, equal in principal amount to such beneficial interest, and to have such debt securities in certificated form registered in the names of the beneficial owners, which names shall be provided by DTC's relevant participants (as identified by DTC) to the applicable trustee.

Unless we describe otherwise in the applicable prospectus supplement, debt securities so issued in certificated form will be issued in denominations of $1,000 or any integral multiple thereof, and will be issued in registered form only, without coupons.

DTC will act as securities depository for the debt securities. The debt securities will be issued as fully registered securities registered in the name of Cede & Co. (DTC's partnership nominee) or such

other name as may be requested by an authorized representative of DTC. Except as otherwise provided, one fully registered debt security certificate will be issued with respect to each series of the debt securities, each in the aggregate principal amount of such series, and will be deposited with DTC. If, however, the aggregate principal amount of any series exceeds $500 million, one certificate will be issued with respect to each $500 million of principal amount and an additional certificate will be issued with respect to any remaining principal amount of such series.

DTC, the world's largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC's participants ("Direct Participants") deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between Direct Participants' accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly ("Indirect Participants"). The DTC rules applicable to its Participants are on file with the SEC. More information about DTC can be found at www.dtcc.com. Information contained on, or accessible through, these websites is not part of, or incorporated by reference into, this prospectus.

Purchases of debt securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the debt securities on DTC's records. The ownership interest of each actual purchaser of each debt security ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchase, but Beneficial Owners are, however, expected to receive a written confirmation providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in debt securities are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in debt securities, except in the event that use of the book-entry system for the debt securities is discontinued.

To facilitate subsequent transfers, all debt securities deposited by Direct Participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co, or such other name as may be requested by an authorized representative of DTC. The deposit of the debt securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the debt securities; DTC's records reflect only the identities of the Direct Participants to whose accounts debt securities are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the debt securities unless authorized by a Direct Participant in accordance with DTC's procedures. Under its usual procedures, DTC mails a proxy (an "Omnibus Proxy") to the issuer as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.'s consenting or voting rights to those Direct Participants to whose accounts the debt securities are credited on the record date (identified on a list attached to the Omnibus Proxy).

Principal, premium, if any, interest payments and redemption proceeds on the debt securities will be made to Cede & Co., or such other nominee, as may be requested by an authorized representative of DTC. DTC's practice is to credit Direct Participants' accounts upon DTC's receipt of funds and corresponding detail information from us or the trustee, on the payment date in accordance with their respective holdings shown on DTC's records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name" and will be the responsibility of such Participant and not of DTC, nor its nominee, the Trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, interest and redemption proceeds to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is our responsibility or the Trustee's, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

If applicable, redemption notices shall be sent to DTC. If less than all of the book-entry notes within an issue are being redeemed, DTC's practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

A Beneficial Owner shall give notice of any option to elect to have its book-entry notes repaid by us, through its Participant, to the Trustee, and shall effect delivery of such book-entry notes by causing the Direct Participant to transfer the Participant's interest in the global security or securities representing such book-entry notes, on DTC's records, to the Trustee. The requirement for physical delivery of book-entry notes in connection with a demand for repayment will be deemed satisfied when the ownership rights in the global security or securities representing such book-entry notes are transferred by Direct Participants on DTC's records and followed by a book-entry credit of tendered securities to the Trustee's DTC account.

DTC may discontinue providing its services as securities depository with respect to the debt securities at any time by giving reasonable notice to the Trustee or us. Under such circumstances, in the event that a successor securities depository is not appointed, debt security certificates are required to be printed and delivered.

We may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depository). In that event, debt security certificates will be printed and delivered to DTC.

The information in this section concerning DTC and DTC's book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

Unless stated otherwise in the prospectus supplement, the underwriters or agents with respect to a series of debt securities issued as global securities will be Direct Participants in DTC.

Neither we, the Trustee nor any applicable paying agent will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in a global security, or for maintaining, supervising or reviewing any records relating to such beneficial interest.

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."

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 February 5, 2013, 135,499,506 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.

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 Federal Deposit Insurance Corporation, 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 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 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.

Our board of directors may authorize the issuance of shares of preferred stock in one or more series and may determine, with respect to any such series, the rights, preferences, privileges and restrictions of the preferred stock, including:

The shares of preferred stock we or any selling stockholder may offer from time to time under this prospectus, when issued, will be duly authorized, fully paid and nonassessable, and holders of preferred stock will not have any preemptive rights.

The issuance of preferred stock could have the effect of delaying, deferring or preventing a change in control or other transaction that might involve a premium price for our common stock or otherwise be in the best interests of our stockholders. In addition, any preferred stock that we issue could rank senior to our common stock with respect to the payment of distributions, in which case we could not pay any distributions on our common stock until full distributions have been paid with respect to such preferred stock.

The rights, preferences, privileges and restrictions of each series of preferred stock will be fixed by articles supplementary relating to the series. We will describe the specific terms of the particular series of preferred stock in the prospectus supplement relating to that series, which terms will include:

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.

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, our 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 our 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 an Internal Revenue Service ("IRS") ruling satisfactory to our board of directors with respect to our qualification as a REIT.

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.

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 a trustee (the "charitable 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 charitable 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 New York Stock Exchange ("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 charitable 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 charitable trustee must distribute the net proceeds of the sale to the purported record transferee and any dividends or other distributions held by the charitable trustee with respect to such shares of stock will be paid to the charitable beneficiary.

If we do not buy the shares, the charitable 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 charitable trustee who could own the shares without violating the ownership limits. After that, the charitable 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 charitable 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 charitable trustee upon demand. The purported beneficial transferee or purported record transferee has no rights in the shares held by the charitable trustee.

The charitable 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 charitable 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 charitable trustee upon demand. Any dividend or other distribution authorized but unpaid will be paid when due to the charitable trustee.

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

However, if we have already taken irreversible corporate action, then the charitable 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.

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

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:

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 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 our board of directors in setting the terms of any class or series of preferred stock, any vacancy on our 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.

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.

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 our 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 our 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.

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

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

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

The control share acquisition statute does not apply to (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 of Title 3 of the MGCL permits a Maryland corporation with a class of equity securities registered under the Exchange Act, and at least three independent directors to elect to be subject, by provision in its charter or bylaws or a resolution of its board of directors and notwithstanding any contrary provision in the charter or bylaws, to any or all of five provisions:

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 our board, which removal will be allowed only for cause, (2) vest in our 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 our 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.

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 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.

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.

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.

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 into the classified board or other provisions of Subtitle 8, these provisions of the MGCL could have similar anti-takeover effects.

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 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:

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:

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:

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.

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, 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.

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.

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 an investment in debt securities or the acquisition, ownership, disposition and exercise of the warrants will be described in the related prospectus supplement. 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 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:

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.

We have elected to be taxed as a REIT for U.S. federal income tax purposes commencing with our initial taxable year ended December 31, 2009. 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, commencing with our initial taxable year ended December 31, 2009, we have been organized and operated in conformity with the requirements for qualification and taxation as a REIT under the Internal Revenue Code, and that our proposed method of operation will enable us to continue to meet the requirements for qualification and taxation as a REIT. 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 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.

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.

Under current law, most domestic stockholders that are individuals, trusts or estates are taxed on corporate dividends at a maximum rate of 20% (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. 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:

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.

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

(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;

(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, was 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.

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 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 "earnings stripping" rules of Section 163(j) of the Internal Revenue Code 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 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 TRS 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 or properties that we originate or purchase 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. The TRS through which any such sales of loans are made may be treated as a dealer for federal income tax purposes. As a dealer, the TRS would in general mark all the loans it holds on the last day of each taxable year to their market value, and would 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.

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 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 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 provide limited services to residents at residential properties we own. We intend that services with respect to properties that will be provided by us directly will be usually or customarily rendered in connection with the rental of space for occupancy only and will not be otherwise rendered to particular tenants or, if considered impermissible tenant services, income from the provision of such services will be received by an independent contractor from which we do not receive or derive any income.

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.

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.

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 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. We will generally accrue market discount during the term of the debt instrument and report the accrued market discount as income when, and to the extent that, any payment of principal of the debt instrument is made. 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 income will be accrued 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.

Finally, we may be required under the terms of indebtedness that we incur (including certain securitizations), to use cash received from interest payments to make principal payments on that indebtedness, with the effect of recognizing income but not having a corresponding amount of cash available for distribution to our stockholders.

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 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."

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 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.

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.

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:

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 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. This may be an issue, in particular, with respect to our investments in distressed or modified debt instruments. See "—Timing Differences Between Receipt of Cash and Recognition of Income." Potential sources of non-cash taxable income include:

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. 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.

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.

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 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 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.

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.

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, 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.

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

Under the Treasury regulations, 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:

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 "—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.

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. 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.

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 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."

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.

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.

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 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 20% maximum federal rate) 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

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 20% 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.

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.

In certain circumstances, we may make a taxable distribution of our stock as part of a distribution in which stockholders may elect to receive stock or (subject to a limit measured as a percentage of the total distribution) cash. In this circumstance, a stockholder generally must include the sum of the value of our stock and the amount of cash received in its gross income as dividend income to the extent that such stockholder's share of the distribution is made out of its share of the portion of our current and accumulated earnings and profits allocable to such distribution. The value of any of our stock received as part of a distribution is generally equal to the amount of cash that could have been received instead of our stock. Depending on the circumstances of the stockholder, the tax on the distribution may exceed the amount of the distribution received in cash, in which case such stockholder would have to pay the tax using cash from other sources. A stockholder that received our stock pursuant to a distribution generally has a tax basis in such stock equal to the amount of cash that would have been received instead of our stock as described above, and a holding period in such stock that begins on the day following the payment date for the distribution.

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 20% if the stock is held for more than one year, and will be taxed at ordinary income rates (of up to 39.6%) 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.

Medicare Contribution Tax on Unearned Income. A U.S. person that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, will be subject to a 3.8% tax on the lesser of (1) the U.S. person's "net investment income" for the relevant taxable year and (2) the excess of the U.S. person's modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000 depending on the individual's circumstances). Net investment income generally includes dividends, and net gains from the disposition of stock, unless such income or gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). A U.S. person that is an individual, estate or trust should consult its tax advisor regarding the applicability of the Medicare tax to its income and gains in respect of its 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% 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 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.

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:

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.

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 that are not dividends, that is, are not paid 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. A 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. However, if our stock constitutes a USRPI, which will be determined in the manner 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 may 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 with respect to 5% (or less) stockholders, 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 any distribution to a non-U.S. holder to the extent attributable to gain from sales or exchanges by us of USRPIs. The amount withheld would be creditable against the non-U.S. holder's U.S. tax liability. 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.

Notwithstanding the foregoing, 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 one- year period 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 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, because our stock is publicly traded 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.

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.

HIRE Act. Legislation enacted in 2010 will generally impose a 30% withholding tax on dividends on shares of our stock and the gross proceeds of a disposition of shares of our 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 stock may be eligible for refunds or credits of those taxes. The withholding provisions described above will apply to payments of dividends on shares of our stock made on or after January 1, 2014 and to payments of gross proceeds of a disposition of shares of our stock on or after January 1, 2017. You are encouraged to consult with your own tax advisor regarding the possible implications of this legislation on your investment in shares of our stock.

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.

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.

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.

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.

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

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

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 through 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.

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.

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.

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.

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.

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 Industry Regulatory Authority, Inc. ("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.

Unless otherwise indicated in the applicable prospectus supplement, certain legal matters will be passed upon for us by Sidley Austin LLP, New York, New York, and, with respect to matters of Maryland law, by Foley & Lardner LLP, Washington, D.C. 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.
