PROSPECTUS

DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN

3,500,000 Shares

COMMON STOCK

---

        With this prospectus, we are offering participation in our Dividend Reinvestment and Stock Purchase Plan, or the Plan, to holders of our common stock, as well as to other interested investors. The Plan is a simple, convenient and low-cost means of investing in our common stock.

        You may participate in the Plan if you own our common stock. If you do not own any common stock, you can participate in the Plan by making your initial investment in our common stock through the Plan with a minimum initial investment of $1,000 (but no more than $10,000, unless we waive this limit). Once you are enrolled in the Plan, you may have the cash dividends on all or a portion of your common stock reinvested automatically with us at a discount to the market price ranging from 0% to 3%. The discount is initially expected to be 0%, but may be adjusted by us in our discretion at any time. Once you are enrolled in the Plan, you may buy additional shares of common stock by making optional cash investments of $250 to $10,000 per month. In some instances, however, we may permit greater optional cash investments.

        Your participation in the Plan is entirely voluntary, and you may terminate your participation at any time. If you do not elect to participate in the Plan, you will continue to receive cash dividends, if and when declared by our board of directors, in the usual manner. Our common stock is listed on the New York Stock Exchange, or the NYSE, under the ticker symbol "SLG." On February 21, 2018, the closing sale price of our common stock on the NYSE was $94.50 per share.

        Investing in our common stock involves risks that are described in the "Risk Factors" section of our Annual Report on Form 10-K for the year ended December 31, 2017 and other reports that we may file from time to time with the Securities and Exchange Commission.

        Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or has determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

   

The date of this prospectus is February 23, 2018.

TERMS AND CONDITIONS OF THE PLAN

        The following questions and answers state the terms of our Dividend Reinvestment and Stock Purchase Plan and explain how it works. If you are a stockholder and do not participate in the Plan, you will receive cash dividends in the usual manner, as and when we declare and pay them. All references in this prospectus to "common stock" refer to our common stock, par value $0.01 per share.

PURPOSE

1.

WHAT IS THE PURPOSE OF THE PLAN?

        The primary purpose of the Plan is to give holders of record of our common stock and other interested investors a convenient and economical way to purchase and to reinvest all or a portion of their cash dividends in shares of common stock. A secondary purpose of the Plan is to provide us another way to raise additional capital for general corporate purposes through the sale of common stock under the Plan.

PARTICIPATION OPTIONS

2.

WHAT ARE MY INVESTMENT OPTIONS UNDER THE PLAN?

        Once enrolled in the Plan, you may buy shares of common stock through any of the following investment options:

•

FULL DIVIDEND REINVESTMENT.  You may reinvest cash dividends paid on all of your common stock to purchase additional shares of common stock. This option also permits you to make optional cash investments from $250 to $10,000 per month to buy additional shares of common stock.



•

PARTIAL DIVIDEND REINVESTMENT.  You may receive cash dividends paid on a specified number of your shares of common stock. We will continue to reinvest your cash dividends on the remaining shares of common stock, when and if declared by our board of directors. This option also permits you to make optional cash investments from $250 to $10,000 per month to buy additional shares of common stock.



•

OPTIONAL CASH INVESTMENTS ONLY.  You may make optional cash investments from $250 to $10,000 per month to buy additional shares of common stock. Dividends on shares of common stock credited to your account under the Plan and shares owned by you will be paid to you in cash, when and if declared by our board of directors, on the shares of common stock owned by you then or in the future, unless you designate the shares for reinvestment pursuant to the Plan. If you currently do not own any of our common stock, you can participate in the Plan by making a minimum initial investment of $1,000. You may request, and in some instances we may approve, a waiver from us permitting you to make optional cash investments in an amount greater than $10,000 per month. See Question 10 to learn how to request such a waiver.

BENEFITS AND DISADVANTAGES

3.

WHAT ARE THE BENEFITS AND DISADVANTAGES OF THE PLAN?

BENEFITS

        Before deciding whether to participate in the Plan, you should consider the following benefits of the Plan:

•

You may have the cash dividends on all or a portion of your shares of common stock reinvested automatically with us at a discount to the market price ranging from 0% to 3%.

7

---

Table of Contents

•

There are no costs associated with the Plan that you must pay, except for costs related to your voluntary selling of shares of common stock or withdrawal from the Plan. Therefore, you will not pay per share processing fees or service fees to purchase common stock through the Plan. Please see the "Plan Service Fees Schedule" attached as the Schedule hereto for a detailed description of the costs for which you will be responsible.



•

You will get the convenience of having all or a portion of your cash dividends automatically reinvested in additional shares of common stock. Since the Administrator will credit fractional shares of common stock to your Plan account, you will receive full investment of your dividends and optional cash investments.



•

You will have the option of having your share certificates held for safekeeping by the Administrator, insuring your protection against loss, theft or destruction of the certificates representing your shares of common stock.



•

You will simplify your record keeping by receiving periodic statements which will reflect all current activity in your Plan account, including purchases, sales and latest balances.



•

You will have the flexibility of making optional cash investments of $250 to $10,000 in any one month to buy additional shares of common stock. You may make these optional cash investments on a regular or occasional basis.



•

Shares of common stock purchased directly from us under the Plan pursuant to an approved request for waiver may be issued without payment of per share processing fees. Initially, optional cash investments of less than $10,000 will not be subject to a discount, but we reserve the right to grant a discount in the future.



•

At any time, you may direct the Administrator to sell or transfer all or a portion of the shares of common stock held in your Plan account.

DISADVANTAGES

        Before deciding whether to participate in the Plan, you should consider the following disadvantages of the Plan:

•

We are not now offering a discount on purchases of common stock made through dividend reinvestments or optional cash investments, although we reserve the right to offer any discount in the future.



•

Without giving you prior notice, we may direct the Administrator to buy shares of common stock under the Plan either directly from us or in the open market or in privately negotiated transactions with third parties.



•

Your reinvestment of cash dividends will result in you being treated for federal income tax purposes as having received a dividend on the dividend payment date, to the extent of our earnings and profits. The dividend may give rise to a liability for the payment of income tax without providing you with immediate cash to pay the tax when it becomes due.



•

You may not know the actual number of shares of common stock that the Administrator of the Plan buys for your account until after the applicable Investment Date.



•

You must decide to make optional cash investments prior to the applicable Investment Date. Accordingly, your investments may be exposed to changes in market conditions.



•

The purchase price for the shares of common stock you purchase through the Plan is based on the average market prices for the shares during the applicable "Pricing Period." The "Pricing

8

---

Table of Contents

Periods" are described in Question 8. As a result, your purchase price may exceed (or be less than) the price of acquiring the shares on the open market on the applicable Investment Date.

•

Sales of common stock held in your Plan account may be delayed.



•

You will pay per share processing fees or, as described in the Schedule attached hereto, per share processing and transaction fees, on the sale of common stock held in your Plan account.



•

The Administrator will not pay interest on funds that it holds pending reinvestment or investment.



•

You may not pledge shares of common stock deposited in your Plan account unless you withdraw the shares from the Plan.



•

If you direct the Plan to sell less than all of your shares of common stock held by the Plan, you will not be able to specifically identify which shares are sold for purposes of determining whether the sale results in short-term or long-term gain or loss for income tax purposes.

PARTICIPATION

5.

WHO IS ELIGIBLE TO PARTICIPATE IN THE PLAN?

        You may participate in the Plan if you qualify as either of the following:

•

You are a "registered holder," a person whose shares are registered in our transfer books in your name, or



•

You are a "beneficial owner," a holder of shares who has beneficial ownership of shares that are registered in a name other than your name (for example, in the name of a broker, bank or other nominee). Registered holders may participate in the Plan directly. If you are not a registered holder, you must either become a registered holder by having your shares transferred into your own name, or you must make arrangements with your broker, bank or other nominee to participate in the Plan on your behalf. Most major brokers, banks and other nominees will make such arrangements on your request. For instructions on enrolling, see Question 6.

        MINIMUM OWNERSHIP INTEREST.    There is no minimum requirement as to the number of shares of common stock that you must hold in your Plan account in order to participate in the Plan.

        If you are an interested investor but not yet a stockholder, you initially can purchase from us at least $1,000, but no more than $10,000 (unless we waive this limitation), of common stock in order to participate in the Plan. This initial purchase will enable you to participate in both the optional cash investment and dividend reinvestment portions of the Plan. You may purchase shares of common stock pursuant to this paragraph in the manner set forth in the response to Question 8.

        NON-TRANSFERABILITY OF RIGHT TO PARTICIPATE.    You may not transfer your right to participate in the Plan to another person.

        FOREIGN LAW RESTRICTIONS.    You may not participate in the Plan if it would be unlawful for you to do so in the jurisdiction where you are a citizen or reside. If you are a citizen or resident of a country other than the United States, you should confirm that by participating in the Plan you will not violate local laws governing, among other things, taxes, currency and exchange controls, stock registration and foreign investments.

        EXCLUSION FROM PLAN FOR SHORT-TERM TRADING OR OTHER PRACTICES.    You should not use the Plan to engage in short-term trading activities that could change the normal trading volume of the common stock. If you do engage in short-term trading activities, we may prevent you from participating in the Plan. We reserve the right to modify, suspend or terminate participation in the Plan, by otherwise eligible holders of common stock, in order to eliminate practices which are, in our sole discretion, not consistent with the purposes or operation of the Plan or which adversely affect the price of the common stock. In addition to short-term trading activities, we reserve the right to prevent you from participating in the Plan for any other reason. It is in our sole discretion to exclude you from or terminate your participation in the Plan.

ENROLLMENT

6.

HOW DO I ENROLL IN THE PLAN?

        If you are eligible to participate in the Plan, you may join the Plan at any time via the Internet at www.computershare.com/investor, or by submitting an Enrollment Form to the Administrator. Once you enroll in the Plan, you will remain enrolled until you withdraw from the Plan or we terminate the Plan.

        THE ENROLLMENT FORM.    If you own shares of SLG common stock registered in your name, you can enroll online at www.computershare.com/investor or by mailing a completed Enrollment Form to the Administrator in the enclosed courtesy reply envelope. If your shares of common stock are

10

---

Table of Contents

registered in more than one name (such as joint tenants or trustees), all registered holders must sign the Enrollment Form. If you are eligible to participate in the Plan, you may sign and return the Enrollment Form to join the Plan at any time.

        If you are a beneficial owner but not a record holder of shares of common stock, you must instruct your broker, bank or other nominee in whose name your shares are held to participate in the Plan on your behalf.

        If you are an interested investor but not presently our stockholder, and you desire to participate in the Plan by making an initial purchase from us of at least $1,000, but no more than $10,000, worth of our common stock, you may join the Plan online at www.computershare.com/investor or by signing an Initial Enrollment Form and mailing it, together with the funds, to the Administrator. You may obtain an Enrollment Package at any time online, by calling the toll-free number provided or by writing to the Administrator at the address set forth in Question 4.

        CHOOSING YOUR INVESTMENT OPTION.    When completing the Enrollment Form, you should choose one of the three investment options discussed in Question 2 and repeated below:

•

"Full Dividend Reinvestment"—This option directs the Administrator to reinvest the cash dividends paid on all of the shares of common stock owned by you then or in the future in shares of common stock. This option also permits you to make optional cash investments from $250 to $10,000 per month to buy additional shares of common stock.



•

"Partial Dividend Reinvestment"—This option directs the Administrator to pay cash dividends on a specified number of shares of common stock then owned by you in shares of common stock. We will continue to reinvest your cash dividends on the remaining shares of common stock, when and if declared by our board of directors. This option also permits you to make optional cash investments from $250 to $10,000 per month to buy additional shares of common stock.



•

"Optional Cash Investments Only"—This option permits you to make optional cash investments from $250 to $10,000 per month to buy additional shares of common stock. Dividends on shares of common stock credited to your account under the Plan and shares of common stock owned by you will be paid to you in cash, when and if declared by our board of directors, on the shares of common stock owned by you then or in the future, unless you designate the shares for reinvestment pursuant to the Plan. You should choose your investment option by checking the appropriate box on the Enrollment Form. If you sign and return an Enrollment Form without checking an option, the Administrator will choose the "Full Dividend Reinvestment" option and will reinvest all cash dividends on all shares of common stock registered in your name.

        The Administrator automatically will reinvest all cash dividends paid on all shares of common stock that you have designated for participation in the Plan until you indicate otherwise or withdraw from the Plan, or until we terminate the Plan. If you have elected to have your dividends reinvested, we will pay to the Administrator dividends on all shares of common stock held in your Plan account. The Administrator will credit the common stock purchased with your reinvested dividends to your Plan account.

        CHANGING YOUR INVESTMENT OPTION.    You may change your investment option by logging into your account online or completing and signing a new Enrollment Form and returning it to the Administrator of the Plan. The Administrator must receive any change before the record date for a dividend payment in order for the change to become effective for that dividend payment. The Administrator also must receive any change in the number of shares of common stock that you have designated for partial dividend reinvestment before the record date for a dividend payment in order to reinvest for the new number of shares on the next Investment Date.

Table of Contents

7.

WHEN WILL MY PARTICIPATION IN THE PLAN BEGIN?

        The date on which the Administrator receives your properly completed Enrollment Form will determine the date on which the Administrator will buy shares of common stock for your account. If you choose either the full or partial dividend reinvestment option, the Administrator will begin to reinvest dividends on the Investment Date after receipt of your Enrollment Form, provided it receives the Enrollment Form before the record date set for the related dividend payment.

        If you choose the optional cash investments only option and wish to invest $10,000 or less in any one month, the Administrator will purchase shares of common stock for you on the Investment Date after receipt of both your Enrollment Form and the funds to be invested, provided it receives the Enrollment Form and funds by 12:00 p.m. on the last business day immediately preceding the Investment Date. If the Administrator receives your Enrollment Form and funds for optional cash investment after such time before the Investment Date, then the Administrator generally will hold your funds, without interest, for investment on the next Investment Date. Please see the provisions of Question 10 if you wish to invest more than $10,000. Once you enroll in the Plan, you will remain enrolled in the Plan until you withdraw from the Plan or we terminate the Plan.

PURCHASES

8.

HOW ARE SHARES PURCHASED UNDER THE PLAN?

        INITIAL PURCHASE OF COMMON STOCK.    If you are an interested investor but not yet our stockholder, then you initially may direct the Administrator to purchase for your account at least $1,000 (but no more than $10,000) worth of common stock, making you eligible to participate in the Plan. You may purchase your initial shares via EFT through the Administrator's website at www.computershare.com/investor. Alternatively, you make initial investment by completing, signing, and returning the Enrollment Form to the Administrator together with a check payable to "Computershare/SL Green" in an amount from $1,000 to $10,000. The funds must be in U.S. currency drawn on a U.S. bank and mailed to the Administrator at the address set forth in Question 4. Third-party checks, cash, money orders, travelers checks, cashiers checks and checks not drawn on a U.S. Bank or not in U.S. currency will not be accepted and will be returned to the sender. The other provisions of this Question 8 will apply to your purchase of shares of common stock in this manner.

        SOURCE OF THE SHARES OF COMMON STOCK.    The Administrator will use all dividends reinvested through the Plan and all optional cash investments to buy either shares of common stock directly from us, or shares of common stock on the open market or in privately negotiated transactions with third parties, or a combination thereof, at our discretion. Shares of common stock purchased directly from us will consist of authorized but unissued shares of common stock or shares held in our treasury, if any. Shares of common stock purchased on the open market will be made through a broker dealer which may be affiliated with the Administrator. We cannot revise our determination that shares purchased through the Plan will be purchased either (1) from us, or (2) on the open market or in privately negotiated transactions, more than once every three months.

        INVESTMENT DATES.    If the Administrator is purchasing your shares of common stock with reinvested dividends, your shares will be purchased beginning on the dividend payment date, or if that date is not a trading day, then on the next trading day. A trading day means a day on which trades in shares of common stock are reported on the principal market for those shares, which is currently the NYSE. If the Administrator is purchasing your shares of common stock with cash investments, your shares will be purchased beginning on the fifteenth day of the month, or if that date is not a trading day, then on the next trading day.

12

---

Table of Contents

        You should be aware that when the Administrator is purchasing shares of common stock on the open market, regulations may require the Administrator to make the purchases on a date later than the date specified by the Plan.

        The date on which the Administrator purchases shares of common stock directly from us, or the first date on which the Administrator purchases shares in the open market, with respect to any dividend reinvestment or optional cash investment is sometimes referred to in the Plan as the "Investment Date" for the shares of common stock purchased in connection with that dividend reinvestment or optional cash investment.

        In the past, record dates for dividends have preceded the dividend payment dates by approximately two weeks. We historically have paid dividends on or about the fifteenth business day of each January, April, July and October. We cannot assure you that we will pay dividends according to this schedule in the future, and nothing contained in the Plan obligates us to do so. Neither we nor the Administrator will be liable when conditions, including compliance with the rules and regulations of the SEC prevent the Administrator from buying shares of common stock or interfere with the timing of purchases.

        We pay dividends as and when declared by our board of directors. We cannot assure you that we will declare or pay a dividend in the future, and nothing contained in the Plan obligates us to do so. The Plan does not represent a guarantee of future dividends.

        PRICE OF SHARES OF COMMON STOCK.    Shares of common stock purchased through the Plan directly from us with reinvested dividends will be acquired at a price to you equal to the average of the daily high and low sales prices of the shares reported as NYSE Composite Transactions for the "Dividend Reinvestment Pricing Period," the five trading days immediately preceding the applicable Investment Date.

        For shares of common stock purchased through the Plan on the open market with reinvested dividends the Administrator may combine your purchase requests with other purchase requests received from other participants and will generally batch purchase types (dividend and cash investments) for separate execution by the Administrator's broker. The Administrator may also direct its broker to execute each purchase type in several batches throughout a trading day. Depending on the number of shares being purchased and current trading volume in the shares, the Administrator's broker may execute purchases for any batch or batches in multiple transactions and over more than one day. If different purchase types are batched, the price per share of the common shares purchased for each participant's account, whether purchased with reinvested dividends, with initial cash investments, or with optional cash, shall be the weighted average price of the specific batch for such shares purchased by the Administrator's broker on that particular Investment Date.

        Shares of common stock purchased with reinvested dividends may reflect a discount ranging from 0% to 3%. The discount is initially expected to be 0%, but may be adjusted by us at our discretion at any time.

        Shares of common stock purchased through the Plan directly from us with cash investments of less than $10,000 will be acquired at a price to you equal to 100% of the average of the daily high and low sales prices of the shares reported as NYSE Composite Transactions for the "Cash Investment Pricing Period," the five trading days immediately preceding the applicable Investment Date. We reserve the right to grant a discount in the future for these investments.

        For shares of common stock purchased through the Plan on the open market with cash investments the Administrator may combine your purchase requests with other purchase requests received from other participants and will generally batch purchase types (dividend and cash investments) for separate execution by the Administrator's broker. The Administrator may also direct its broker to execute each purchase type in several batches throughout a trading day. Depending on the number of shares being purchased and current trading volume in the shares, the Administrator's broker

13

Table of Contents

may execute purchases for any batch or batches in multiple transactions and over more than one day. If different purchase types are batched, the price per share of the common shares purchased for each participant's account, whether purchased with reinvested dividends, with initial cash investments, or with optional cash, shall be the weighted average price of the specific batch for such shares purchased by the Administrator's broker on that particular Investment Date.

        Shares of common stock purchased pursuant to a request for waiver (as described in Question 10) will be acquired at a price to you equal to the volume-weighted average price of our common stock as reported by the NYSE for the applicable Investment Date. Shares purchased pursuant to a request for waiver are also subject to the qualifications set forth under "Minimum Waiver Price" in Question 10 below.

        The price to you for shares of common stock purchased through the Plan, whether directly from us or in open market transactions, is sometimes referred to as the "purchase price" for such shares. Although we will pay all per share processing fees on shares purchased on the open market, for tax purposes, these fees may be considered as additional taxable dividend income to you. See Question 16 for a discussion of the principal federal income tax consequences of participating in the Plan. These fees are not expected to be substantial.

        Notwithstanding anything else to the contrary herein, under no circumstances will the price of a share of common stock acquired under the Plan (whether by reinvested dividends or cash payments) be less than 95% of the fair market value of such share determined as of the applicable Investment Date. For purposes of making the foregoing computation, (1) the fair market value of a share of common stock is the weighted average share price of all shares sold on the open market on the applicable Investment Date, and (2) if any trading fee is paid to acquire a share and not reimbursed by the Plan participant, it will be treated as an additional reduction in the price of such share.

        NUMBER OF SHARES TO BE PURCHASED.    If you elect to participate in the Plan by reinvesting your dividends, the Administrator will invest for you the total dollar amount equal to the sum of (1) the dividend on all shares of common stock, including fractional shares, held in your Plan account for which you have requested dividend reinvestment and (2) any optional cash investments to be made as of that Investment Date.

        If you elect to make only optional cash investments, the Administrator will invest for you the total dollar amount equal to any optional cash investments to be made as of that Investment Date.

        As of any Investment Date, the Administrator will purchase for your account the number of shares of common stock equal to the total dollar amount to be invested for you, as described above, divided by the applicable purchase price. The Administrator will deduct from the amount to be invested for you any amount that we are required to deduct for withholding tax purposes.

        ADMINISTRATOR'S CONTROL OF PURCHASE TERMS.    With respect to purchases of shares of common stock that the Administrator makes under the Plan, the Administrator, or a broker that the Administrator selects, will determine the following:

•

the exact timing of open market purchases;



•

the number of shares of common stock, if any, that the Administrator purchases on any one day or at any time of that day;



•

the prices for the shares of common stock that the Administrator pays;



•

the markets on which the Administrator makes the purchases; and



•

the persons, including brokers and dealers, from or through which the Administrator makes the purchases.

        COMMINGLING OF FUNDS.    When making purchases for an account under the Plan, we or the Administrator may commingle your funds with those of other investors participating in the Plan.

HOW DO I MAKE OPTIONAL CASH INVESTMENTS?

        You may make optional cash investments at any time if you are (1) a registered holder of common stock or (2) an interested investor who has purchased from us at least $1,000 worth of common stock.

        INITIAL CASH INVESTMENTS.    You may make an initial cash investment when enrolling in the Plan via the Internet or by sending your properly completed Initial Enrollment Form along with a check, payable to "Computershare/SL Green." You may send an amount from $1,000 to $10,000 made out in U.S. funds drawn on a U.S. bank to the Administrator at the address set forth in Question 4 for receipt by the Administrator by 12:00 p.m. on the last business day preceding an Investment Date.

        You may also make your initial cash investment by going to the Administrator's website, www.computershare.com/investor, and authorizing a one-time online bank debit from an account at U.S. bank or financial institution.

        Please see Question 10 if you wish to make an optional cash investment of more than $10,000 in any month.

        OPTIONAL CASH INVESTMENTS.    Once you enroll in the Plan and make an initial investment, whether by dividend reinvestment or optional cash investment, the Administrator will attach a tear-off form to each statement of account it sends to you. To make an optional cash investment once enrolled in the Plan, you should return the tear-off portion of your statement and a check payable to the "Computershare/SL Green," in an amount from $250 to $10,000 per month made out in U.S. funds drawn on a U.S. bank to the Administrator at the address set forth on the tear-off form so that it is received by 12:00 p.m. eastern time on the last business day preceding an Investment Date.

        The Administrator will hold, without interest, all optional cash investments that it receives after 12:00 p.m. eastern time on the last business day before an Investment Date and before the next Investment Date. The Administrator will invest the held-over funds on the next Investment Date, provided that the next Investment Date falls within 35 or fewer days. If the next Investment Date will occur in more than 35 days, then the Administrator will return the funds to you, without interest.

        You may also make optional cash investment by going to the Administrator's website, www.computershare.com/investor, and authorizing a one-time online bank debit from an account at U.S. bank or financial institution.

        Additionally, you may make automatic investments in an amount from $250 to $10,000 per month through an Automated Clearing House (ACH) withdrawal from a predesignated account at a U.S. bank or financial institution. To initiate automatic deductions, you may enroll through the Administrator's website, www.computershare.com/investor, or, complete and sign a Direct Debit Authorization Form and return it to the Administrator together with a voided blank check or savings account deposit slip for the account from which funds are to be drawn. Forms will be processed and will become effective as promptly as practicable; however, you should allow four to six weeks for your first investment to be initiated. Once automatic deductions are initiated, funds will be drawn from your account on 25th of each month or the next business day if the 25th is not a business day. Automatic deductions will continue at the level you set until you change your instructions by notifying the Administrator.

        MINIMUM AND MAXIMUM LIMITS.    For any Investment Date that you choose to make an optional cash investment, you must invest at least $250 but not more than $10,000. You may invest an amount greater than $10,000 in any month only if you obtain a prior written waiver from us to do so. See Question 10 to learn how to request a waiver. Optional cash investments that exceed $10,000, unless the limit has been waived, will be returned without interest.

        ITEMS TO REMEMBER WHEN MAKING OPTIONAL CASH INVESTMENTS.    When making your optional cash investment, you should consider the following:

•

All optional cash investments must equal at least $250 but not more than $10,000 per month (unless we waive this maximum limit);



•

You do not have to make an optional cash investment in any month;



•

You do not have to send the same amount of cash payment each month;



•

You must make all optional cash investments in United States dollars; and



•

You must send optional cash investments in the form of a check payable to the Administrator. Do not send cash.

        REFUNDS OF UNINVESTED OPTIONAL CASH INVESTMENTS.    To obtain a refund of optional cash investments which the Administrator has not yet invested, you must contact the Administrator at the address set forth in Question 4. The Administrator must receive your request no later than five business days prior to the Investment Date in order to refund your money for the Investment Date.

        NO INTEREST ON OPTIONAL CASH INVESTMENTS.    You will not earn interest on optional cash investments held pending investment. We therefore suggest that you send any optional cash investment that you wish to make so as to reach the Administrator as close as possible to 12:00 p.m. on the last business day preceding the next Investment Date. You should contact the Administrator if you have any questions regarding these dates.

        RETURNED CHECKS FOR INSUFFICIENT FUNDS.    In the event that any check or bank debit is returned unpaid for any reason, the Administrator will consider the request for investment of the money null and void and will immediately remove from the participant's account any shares of common stock purchased upon the prior credit of the money. The Administrator will be entitled to sell these shares of common stock to satisfy any uncollected amounts. If the net proceeds of the sale of the shares of common stock are insufficient to satisfy the balance of the uncollected amounts, the Administrator will be entitled to sell additional shares of common stock from the participant's account to satisfy the uncollected balance. A $35.00 fee will be charged for any deposit returned unpaid.

10.

MAY I INVEST MORE THAN THE PLAN MAXIMUM OF $10,000?

        Yes, if you request a waiver of the optional cash investment limit and we grant your waiver request. Upon receipt of a written waiver form from an investor, we will consider waiving the maximum investment limit. Grants of waiver requests will be made in our sole discretion based on a variety of factors, which may include: our current and projected capital needs, prevailing market prices of our common stock and other securities, and general economic and market conditions.

        Shares purchased in excess of the Plan's maximum investment amount will be priced as follows:

•

Investments for which a waiver has been granted will be made subject to a "pricing period," which will generally consist of one (1) to fifteen (15) separate days during which trading of our common stock is reported on the NYSE. Each of these separate days will be an "investment date," and an equal proportion of the investment amount will be invested on each trading day during such pricing period, subject to the qualifications listed below. The purchase price for

16

---

Table of Contents

shares acquired on a particular investment date will be equal to 100% (subject to change as provided below) of the volume-weighted average price, rounded to four decimal places, of our common stock as reported by the NYSE only, obtained from Bloomberg, LP, for that investment date. Funds for such investments must be received by the Administrator not later than the business day before the first day of the pricing period.

•

We may establish a minimum, or "threshold," price for any pricing period that the volume-weighted average price, rounded to four decimal places, of our common stock must equal or exceed during each trading day of the pricing period for investments made pursuant to a waiver request. Unless otherwise approved by our board of directors, any threshold price we establish must exceed the price determined by applying a discount of up to 3% to the greater of (a) the closing price of our common stock on the day prior to the establishment of the threshold, as reported by the NYSE, and (b) the average of the daily closing price of our common stock (as reported by the NYSE) for the fifteen (15) consecutive trading days immediately prior to the establishment of the threshold.



•

If we decide to establish a threshold price for a particular pricing period, the threshold price for any investments made pursuant to a request for waiver will be a stated dollar amount that the volume-weighted average price, rounded to four decimal places, of our common stock, as reported by the NYSE for each trading day in the relevant pricing period, must equal or exceed. If the threshold price is not satisfied for a trading day in the pricing period, then that trading day and the trading prices for that day will be excluded from the pricing period.



•

We will only establish a threshold price if shares will be purchased directly from us in connection with the relevant pricing period (please see first bullet above). If we have established a threshold price with respect to the relevant pricing period, then we will exclude from the pricing period any trading day that the volume-weighted average price is less than the threshold price and refund that day's proportional investment amount. For example, if the threshold price is not met for two (2) of the trading days in a ten-day pricing period, then we will return 20% of the funds you submitted in connection with your waiver request, without interest, unless we have activated the pricing period extension feature for the pricing period, as described below.



•

Neither we nor the Administrator are required to notify you that a threshold price has been established for any pricing period.



•

We may elect to activate for any particular pricing period a pricing period extension feature which will provide that the initial pricing period be extended by the number of days that the threshold price is not satisfied, subject to a maximum of five (5) trading days. If we elect to activate the pricing period extension feature and the threshold price is satisfied for any additional day that has been added to the initial pricing period, that day will be included as one of the trading days for the pricing period instead of the day on which the threshold price was not met. For example, if the determined pricing period is ten (10) days, and the threshold price is not satisfied for three (3) out of those ten (10) days in the initial pricing period, and we had previously announced in the waiver form that the pricing period extension feature was activated, then the pricing period will be automatically extended, and if the threshold price is satisfied on the next three (3) trading days (or a subset thereof), then those three (3) days (or subset thereof) will become investment dates in lieu of the three (3) days on which the threshold price was not met. As a result, because there were ten (10) trading days during the initial and extended pricing period on which the threshold price was satisfied, all of the funds that you include with your request for waiver will be invested.



•

Newly issued shares purchased pursuant to a request for waiver will be posted to participants' accounts within two (2) business days following the end of the applicable pricing period, or, if we elect to activate the continuous settlement feature, within two (2) business days of each

17

Table of Contents

separate investment date beginning on the first investment date in the relevant pricing period and ending on the final investment date in the relevant pricing period, with an equal amount being invested on each day, subject to the qualifications set forth above. During any month when we are proposing to grant requests for waiver for one or more investments, we may elect to activate the continuous settlement feature for such investments by announcing in the bid-waiver form that we will be doing so. The purchase price of shares acquired on each investment date will be equal to the volume-weighted average price obtained from Bloomberg, LP (unless such service is unavailable, in which case we will designate another service to be utilized before the beginning of the pricing period), rounded to four decimal places, for each of the investment dates during the pricing period, assuming the threshold price is met on that day. For each pricing period (assuming the threshold price is met on each trading day of that pricing period), we would have a separate settlement of each investment dates' purchases, each based on the volume-weighted average price for the trading day relating to each of the investment dates during the pricing period.

•

Waiver request forms and information regarding the establishment of a threshold price, if any, may be obtained by contacting the Administrator on 1-866-230-9138 or at shareholder@computershare.com.

11.

WHAT IF I HAVE MORE THAN ONE ACCOUNT?

        For purposes of the limitations discussed in Question 10, we may aggregate all optional cash investments for Plan participants with more than one account using the same social security or taxpayer identification number, or TIN. If you are unable to supply a social security number or TIN, we may limit your participation to only one Plan account.

        For purposes of the Plan, we may aggregate all Plan accounts that we believe, in our sole discretion, to be under common control or management or to have common ultimate beneficial ownership. Unless we have determined that reinvestment of dividends and optional cash investments for each such account would be consistent with the purposes of the Plan, we will have the right to aggregate all the accounts and to return, without interest, within 30 days of receipt for dividend reinvestment or 35 days of receipt for optional cash investment, any amounts in excess of the investment limitations applicable to a single account received in respect of all the accounts.

CERTIFICATES

12.

WILL I RECEIVE CERTIFICATES FOR SHARES PURCHASED?

        SAFEKEEPING OF CERTIFICATES.    Unless your shares of common stock are held by a broker, bank or other nominee, we will register shares of common stock that the Administrator purchases for your account under the Plan in your name. The Administrator will credit the shares to your Plan account in "book-entry" form. This service protects against the loss, theft or destruction of certificates evidencing shares of common stock.

        You also may send to the Administrator for safekeeping all certificates for shares of common stock which you hold. The Administrator will credit the shares of common stock represented by the certificates to your account in "book-entry" form and will combine the shares with any whole and fractional shares then held in your Plan account. In addition to protecting against the loss, theft or destruction of your certificates, this service also is convenient if and when you sell shares of common stock through the Plan. See Question 13 to learn how to sell your shares of common stock under the Plan.

        You may deposit certificates for shares of common stock into your account regardless of whether you have previously authorized reinvestment of dividends. The Administrator automatically will reinvest

18

---

Table of Contents

all dividends on any shares deposited in accordance with the Plan, unless you have instructed the Administrator otherwise.

        To deposit certificates for safekeeping under the Plan, you should send your share certificates, in non-negotiable form, to the Administrator by insured mail at the address specified in Question 4. You may withdraw any shares deposited for safekeeping by contacting the Administrator.

        ISSUANCE OF CERTIFICATES.    Upon your contacting the Administrator, the Administrator will issue and deliver to you certificates for all whole shares of common stock credited to your Plan account. The Administrator will not issue certificates for fractional shares of common stock but will issue a check representing the value of any fractional shares of common stock valued at the then current market price. Issuance of certificates may be subject to a transaction fee. The Administrator will continue to credit any remaining whole or fractional shares of common stock to your account.

        EFFECT OF REQUESTING CERTIFICATES IN YOUR NAME.    If you request a certificate for whole shares of common stock held in your account, either of the following may occur:

•

If you maintain an account for reinvestment of dividends, then the Administrator will continue to reinvest all dividends on the shares of common stock for which you requested a certificate so long as the shares remain registered in your name; and



•

If you maintain an account only for optional cash investments, then the Administrator will not reinvest dividends on shares of common stock for which you requested a certificate unless and until you submit an Enrollment Form to authorize reinvestment of dividends on the shares registered in your name.

SALE OF SHARES

13.

HOW DO I SELL SHARES?

        SALE OF SHARES HELD IN YOUR ACCOUNT.    Shares are sold on the exchange on which the common shares of the Company trade. The selling price may not be known until the sale is complete.

        You may instruct the Administrator to sell your shares under the Plan in one of four ways—through a Batch Order, Market Order, Day Limit Order or Good-Til-Cancelled (GTC) Limit Order.

        Batch Order:    A batch order is an accumulation of all sales requests for shares of our common stock submitted together as a collective request. Batch orders are submitted on each market day, assuming there are sale requests to be processed. Sale instructions for batch orders received by the Administrator will be processed no later than five (5) business days after the date on which the order is received (except where deferral is required under applicable federal or state laws or regulations), assuming the applicable market is open for trading and sufficient market liquidity exists. All sale requests received in writing will be submitted as batch order sales, unless such requests specify otherwise. Batch order sales may only be requested in writing. In every case of a batch order sale, the price to each selling participant shall be the weighted average sale price obtained by the Administrator's broker for each aggregate order placed by the Administrator and executed by the broker, less a service charge of $15.00 and a processing fee of $0.10 per share sold.

        Market Order:    A market order is a request to sell shares of our common stock promptly at the current market price. Market order sales are only available through the Investor Centre at www.computershare.com/investor or by calling the Administrator directly at 1-866-230-9138. Market order sale requests will be placed promptly upon receipt during market hours (normally 9:30 a.m. to 4:00 p.m. Eastern Standard Time). Market order sale requests received by the Administrator during market hours are final and cannot be stopped or cancelled. Market order sale requests received outside of market hours will be submitted to the Administrator's broker on the next day the market is open.

19

---

Table of Contents

The Administrator will use commercially reasonable efforts to honor requests by participants to cancel market orders placed outside of market hours. Depending on the number of shares being sold and current trading volume in the shares, a market order may only be partially filled or not filled at all on the trading day in which it is placed, in which case the order, or remainder of the order, as applicable, will be cancelled at the end of such day. To determine if your shares were sold, you should check your account online at www.computershare.com/investor or call the Administrator directly at 1-866-230-9138. If your market order sale was not filled and you still want the shares to be sold, you will need to re-enter the sale request. Sales proceeds will equal the market price of the sale obtained by the Administrator's broker, less a service fee of $25.00 and a processing fee of $0.12 per share sold.

        Day Limit Order:    A day limit order is an order to sell shares of our common stock when and if they reach a specific trading price on a specific day. The order is automatically cancelled if the price is not met by the end of that day (or, for orders placed after-market hours, the next day the market is open). Depending on the number of shares of our common stock being sold and the current trading volume in the shares, such an order may only be partially filled, in which case the remainder of the order will be cancelled. The order may be cancelled by the applicable stock exchange, by the Administrator at its sole discretion or, if the Administrator's broker has not filled the order, at your request made online at www.computershare.com/investor or by calling the Administrator directly at 1-866-230-9138. A service fee of $25.00 and a processing fee of $0.12 per share sold will be deducted from the sale proceeds.

        Good-Til-Cancelled (GTC) Limit Order:    A GTC limit order is an order to sell your shares when and if the shares reach a specific trading price at any time while the order remains open (generally up to 30 days). Depending on the number of shares being sold and current trading volume in the shares, sales may be executed in multiple transactions and over more than one day. If an order trades on more than one day during which the market is open, a separate fee will be charged for each such day. The order (or any unexecuted portion thereof) is automatically cancelled if the trading price is not met by the end of the order period. The order may be cancelled by the applicable stock exchange, by the Administrator at its sole discretion or, if the Administrator's broker has not filled the order, at your request made online at www.computershare.com/investor or by calling the Administrator directly at 1-866-230-9138. For each day a trade is placed, a service fee of $25.00 and a processing fee of $0.12 per share sold will be deducted from the sale proceeds.

        All sales requests processed over the telephone by a customer service representative entail an additional fee of $15.00. All per share fees described include any brokerage commissions the Administrator is required to pay. Any fractional share will be rounded up to a whole share for purposes of calculating the per share fee. Fees are deducted from the proceeds derived from the sale. The Administrator may, under certain circumstances, require a transaction request to be submitted in writing. Please contact the Administrator to determine if there are any limitations applicable to your particular sale request. If you sell shares through a Market Order, Day Limit Order or GTC Limit Order, you may choose to receive sales proceeds in a foreign currency or by wire or direct deposit. These services are subject to additional fees and additional terms and conditions, which you must agree to when submitting the transaction.

        All sales are subject to market conditions, system availability and other factors. The actual sale date or price received for any shares sold through the Plan may not be guaranteed.

        If you want to sell shares through your own broker, you may request the broker to transfer shares electronically from your Plan account to your brokerage account. Alternatively, you may request a stock certificate that you can then deliver to your broker.

        Plan participants must perform their own research and must make their own investment decisions. Neither the Administrator nor any of its affiliates will provide any investment recommendations or investment advice with respect to transactions made through the Plan.

Table of Contents

        COSTS OF SELLING SHARES.    The Plan requires you to pay all costs associated with the sale of your shares of common stock under the Plan. Please see the "Plan Service Fees Schedule" attached as the Schedule hereto for a detailed description of the costs.

        TERMINATION OF YOUR ACCOUNT UPON SALE OF ALL SHARES.    If the Administrator sells all shares of common stock held in your Plan account, the Administrator will automatically terminate your account. In this case, you will have to re-enrolled online or complete and file a new Enrollment Form to rejoin the Plan.

REPORTS

14.

HOW WILL I KEEP TRACK OF MY INVESTMENTS?

        Each time the Administrator makes an investment for your account, whether by reinvestment of dividends or by optional cash investment, the Administrator will send you a detailed statement that will provide the following information with respect to your Plan account:

•

total cash dividends received;



•

total optional cash investments received;



•

total number of shares of common stock purchased, including fractional shares;



•

price paid per share of common stock;



•

date of share purchases;



•

total number of shares of common stock sold;



•

price obtained per share of common stock;



•

date of share sales; and



•

total number of shares of common stock in your Plan account. You should retain these statements to determine the tax cost basis of the shares of common stock purchased for your account under the Plan. You may also view your investment information online by logging on to your account at www.computershare.com/investor.

WITHDRAWAL

15.

HOW WOULD I WITHDRAW FROM PARTICIPATION IN THE PLAN?

        HOW TO WITHDRAW FROM THE PLAN.    You may withdraw from the Plan at any time. You may withdraw from the Plan by providing written notice instructing the Administrator to terminate your account, via the IVR system by telephoning the Administrator's shareholder service center at 1-866-230-9138 and making the appropriate menu selections or online at www.computershare.com/investor. The Administrator must receive notice before the record date for any dividend payment in order to terminate your account prior to the dividend payment date. The Administrator will continue to hold your shares in book-entry form unless you request them to be issued or sold.

        SHARE DISPOSITION UPON WITHDRAWAL FROM PLAN.    Upon termination of your Plan account, the Administrator will move any whole shares of common stock in your account to a book-entry position in a direct registration system (DRS) account if requested. The Administrator will convert to cash any fractional shares held in your account at the time of termination at the then current market price of the shares of common stock. You will receive a check for the proceeds less a transaction fee and per share processing fee. After the Administrator terminates your account, we will pay to you all cash dividends on the shares of common stock owned by you unless you rejoin the Plan.

21

Table of Contents

        SELLING SHARES UPON WITHDRAWAL FROM PLAN.    As an alternative to a DRS account, upon termination of your Plan account you may request, via the Internet, IVR system or in writing, that the Administrator sell all or a portion of the shares of common stock (both whole and fractional) in your account. If you instruct the Administrator only to sell a portion of your shares of common stock, then the Administrator will move the remaining shares to a DRS account. The Administrator will send you the proceeds of the sale, less applicable fees, service charges and any taxes. Please see Question 13 to learn how the Administrator sells shares of common stock under the Plan.

        REJOINING THE PLAN AFTER WITHDRAWAL.    After you withdraw from the Plan, you may rejoin the Plan at any time by re-enrolling online or filing a new Enrollment Form with the Administrator. However, the Administrator has the right to reject the Enrollment Form if you repeatedly join and withdraw from the Plan, or for any other reason. The Administrator's exercise of this right is intended to minimize unnecessary administrative expenses and to encourage use of the Plan as a long-term stockholder investment service.

TAXES

16.

WHAT ARE SOME OF THE MATERIAL TAX CONSEQUENCES OF MY PARTICIPATION IN THE PLAN?

        The following summarizes the material federal income tax consequences of participating in the Plan. This summary is for general information only. It does not constitute tax advice and does not reflect every possible tax outcome or consequence that may result from participating in the Plan. Except as otherwise provided, this summary does not address your tax consequences unless you are both a United States citizen (or a resident alien) and hold your stock as a capital asset, as defined in the Internal Revenue Code of 1986, as amended, or the Code. We advise you to consult your own tax advisors to determine the tax consequences particular to your situation, including any applicable federal, state, local or foreign income and other tax consequences that may result from participating in the Plan or selling stock acquired under the Plan. Any state tax consequences will vary from state to state, and any tax consequences to you if you reside outside the United States will vary from jurisdiction to jurisdiction.

        REINVESTMENT OF DIVIDENDS PAID ON SHARES OF COMMON STOCK.    For federal income tax purposes, if you elect to reinvest the cash dividends paid on your shares through the Plan, you will nevertheless be treated as if you received a distribution from us with respect to your shares on the Investment Date. Although there is conflicting authority on this point, we believe that the amount of this deemed distribution (the "Deemed Distribution") should equal the amount that you would have received in cash if you had not elected to reinvest dividends, regardless of whether the reinvestment is made at a discounted price. Shares of stock purchased through reinvestment of dividends do not currently enjoy any discount.

        Your Deemed Distribution will first be treated as a taxable dividend (ordinary income) to the extent of our current and accumulated earnings and profits. To the extent your Deemed Distribution exceeds our current and accumulated earnings and profits, it will be treated as a return of capital to you to the extent of your basis in your shares of common stock, and thereafter as gain from the sale of your shares of common stock. In addition, if we designate part or all of our distributions as capital gain dividends, those designated amounts will be treated by you as long-term capital gains. If you are a corporation, regardless of whether your Deemed Distribution (or any other distribution from us) is taxable as a dividend, you will not be able to claim any dividends received deduction. See "Material United States Federal Income Tax Consequences—Taxation of Stockholders—Taxation of U.S. Stockholders" and "—Taxation of Stockholders—Foreign Account Tax Compliance Act" below.

        Except for costs related to selling shares at your direction, or your withdrawal from the Plan, we will pay all expenses of administering the Plan. Consistent with the conclusion reached by the Internal

22

---

Table of Contents

Revenue Service, or the IRS, in a private letter ruling issued to another taxpayer, we intend to take the position that the costs of administering the Plan do not result in taxable income to you or reduce the basis of your shares. However, because the private letter ruling was issued to another taxpayer, there can be no assurance that the IRS will accept our position on Plan costs. Therefore, we may in the future take a different position with respect to such costs.

        Your tax basis in the shares of common stock acquired for your Plan account on any particular Investment Date will generally equal your Deemed Distribution for that Investment Date. Your holding period in the shares will generally begin on the day after the Investment Date.

        OPTIONAL CASH INVESTMENTS.    For federal income tax purposes, if you elect to purchase shares of common stock from us with a cash investment, you should not be treated as receiving a distribution from us unless we pay trading fees on your behalf or your shares are purchased at a discount, in which case the amount of the deemed distribution (the "Deemed Distribution") should equal the sum of (1) any trading fees we pay on your behalf and (2) the fair market value of any discount (measured by the number of additional shares you acquired as a result of the discount) as of the Investment Date. Because your Deemed Distribution attributable to any discount is based on the fair market value of the discount determined as of the Investment Date, the amount of your Deemed Distribution attributable to discount may differ from the actual amount of the discount. Shares of common stock purchased through the Plan do not currently enjoy any discount. See the discussion earlier under the caption "HOW ARE SHARES PURCHASED UNDER THE PLAN?"

        Your tax basis in the shares of common stock acquired for your Plan account on any particular Investment Date will generally equal the sum of your Deemed Distribution for that Investment Date plus the amount of your cash investment. Your holding period in the shares will generally begin on the day after the Investment Date.

        INCOME TAX WITHHOLDING AND ADMINISTRATIVE EXPENSES.    We or the Administrator may be required to deduct "backup withholding" from the dividends that we pay to any stockholder, regardless of whether the dividends are reinvested pursuant to the Plan. Similarly, the Administrator may be required to deduct backup withholding from the proceeds of shares of common stock sold from your Plan account. You will be subject to backup withholding if:

•

you fail to properly furnish us and the Administrator with your correct TIN;



•

the IRS or any other governmental body or agency notifies us or the Administrator that you have provided an incorrect TIN;



•

the IRS notifies us or the Administrator that backup withholding should be commenced because you failed to properly report dividends paid to you; or



•

when required to do so, you fail to certify, under penalties of perjury, that you are not subject to backup withholding.

        See "Material United States Federal Income Tax Consequences—Taxation of Stockholders—Taxation of U.S. Stockholders—Backup Withholding" and "—Taxation of Stockholders—Foreign Account Tax Compliance Act" below.

        If you are a foreign stockholder whose distributions are subject to federal income tax withholding, the appropriate amount will be withheld from any dividends you elect to reinvest and the balance will be used to purchase shares of common stock that will then be credited to your account.

        All withholding amounts will be withheld from dividends before the dividends are reinvested under the Plan. Therefore, if you are subject to withholding, dividends which would otherwise be available for reinvestment under the Plan will be reduced by the withholding amount. Any amount paid as withholding will be treated as distributed to you and creditable against your income tax liability.

        DISPOSITION.    If you withdraw shares of common stock from the Plan and receive whole shares of common stock, you will not realize any taxable income. However, if you receive cash for a fraction of a share, you will be required to recognize gain or loss with respect to the fraction. You also will be required to recognize a gain or loss upon any sale of your shares, whether the shares are sold by the Administrator on your behalf or sold by you after you withdraw the shares from the Plan. Generally, the amount of the gain or loss that you will be required to recognize will be the difference between the amount that you receive for the shares of common stock and your tax basis in those shares.

WHAT IF I EXCEED THE OWNERSHIP LIMIT SET FORTH IN OUR ARTICLES OF INCORPORATION?

        For us to qualify as a REIT under the Code, among other things, not more than 50% in value of our outstanding capital stock may be owned, directly or indirectly, by five or fewer individuals during the last half of a taxable year, other than the first year, and the shares of capital stock must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months, other than the first year, or during a proportionate part of a shorter taxable year. Pursuant to the Code, common stock held by specific types of entities, such as pension trusts qualifying under Section 401(a) of the Code, United States investment companies registered under the Investment Company Act of 1940, as amended, partnerships, trusts and corporations, will be attributed to the beneficial owners of these entities for purposes of the five or fewer requirement. Generally, for the purposes of restrictions on ownership, the beneficial owners of these entities will be counted as our stockholders.

        In order to protect us against the risk of losing our status as a REIT due to a concentration of ownership among our stockholders, our articles of incorporation, subject to exceptions, provide that no shareholder may own, or be deemed to own by virtue of certain attribution provisions of the Code, more than 9.0%, which we refer to as the "Ownership Limit," of the aggregate number or value of our outstanding shares of common stock. Limitations on the ownership of preferred stock may also be imposed by us. Any direct or indirect ownership of shares of stock in excess of the Ownership Limit or that would result in our disqualification as a REIT, including any transfer that results in shares of capital stock being owned by fewer than 100 persons or results in our being "closely held" within the meaning of Section 856(h) of the Code, shall be null and void, and the intended transferee will acquire no rights to the shares of capital stock. The foregoing restrictions 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. Our board of directors may, in its sole discretion, waive the Ownership Limit if evidence satisfactory to the board of directors and our tax counsel is presented that the changes in ownership will not then or in the future jeopardize our REIT status and our board of directors otherwise decides that this action is in our best interest.

        Shares of capital stock owned, or deemed to be owned, or transferred to a shareholder in excess of the Ownership Limit will automatically be converted into shares of excess stock that will be transferred, by operation of law, to the trustee of a trust for the exclusive benefit of one or more charitable organizations described in Section 170(b)(1)(A) and 170(c) of the Code. The trustee of the trust will be deemed to own the excess stock for the benefit of the charitable beneficiary on the date of the violative transfer to the original transferee-shareholder. Any dividend or distribution paid to the original transferee-shareholder of excess stock prior to the discovery by us that capital stock has been transferred in violation of the provisions of our articles of incorporation shall be repaid to the trustee upon demand. Any dividend or distribution authorized and declared but unpaid shall be rescinded as void from the beginning with respect to the original transferee-shareholder and shall instead be paid to the trustee of the trust for the benefit of the charitable beneficiary. Any vote cast by an original transferee-shareholder of shares of capital stock constituting excess stock prior to the discovery by us that shares of capital stock have been transferred in violation of the provisions of the articles of

24

Table of Contents

incorporation shall be rescinded as void from the beginning. While the excess stock is held in trust, the original transferee-shareholder will be deemed to have given an irrevocable proxy to the trustee to vote the capital stock for the benefit of the charitable beneficiary. The trustee of the trust may transfer the interest in the trust representing the excess stock to any person whose ownership of the shares of capital stock converted into this excess stock would be permitted under the Ownership Limit. If this transfer is made, the interest of the charitable beneficiary shall terminate and the proceeds of the sale shall be payable to the original transferee shareholder and to the charitable beneficiary as described herein. The original transferee-shareholder shall receive the lesser of (a) the price paid by the original transferee-shareholder for the shares of capital stock that were converted into excess stock or, if the original transferee-shareholder did not give value for the shares, the average closing price for the class of shares from which the shares of capital stock were converted for the ten trading days immediately preceding the sale or gift, and (b) the price received by the trustee from the sale or other disposition of the excess stock held in trust. The trustee may reduce the amount payable to the original transferee-shareholder by the amount of dividends and distributions relating to the shares of excess stock which have been paid to the original transferee-shareholder and are owed by the original transferee-shareholder to the trustee. Any proceeds in excess of the amount payable to the original transferee-shareholder shall be paid by the trustee to the charitable beneficiary. Any liquidation distributions relating to excess stock shall be distributed in the same manner as proceeds of a sale of excess stock. If the foregoing transfer restrictions are determined to be void or invalid by virtue of any legal decision, statute, rule or regulations, then the original transferee-shareholder of any shares of excess stock may be deemed, at our option, to have acted as an agent on behalf of us in acquiring the shares of excess stock and to hold the shares of excess stock on our behalf.

        In addition, we will have the right, for a period of 90 days during the time any shares of excess stock are held in trust, to purchase all or any portion of the shares of excess stock at the lesser of (a) the price initially paid for the shares by the original transferee-shareholder, or if the original transferee-shareholder did not give value for the shares, the average closing price for the class of stock from which the shares of excess stock were converted for the ten trading days immediately preceding the sale or gift, and (b) the average closing price for the class of stock from which the shares of excess stock were converted for the ten trading days immediately preceding the date we elect to purchase the shares. We may reduce the amount payable to the original transferee-shareholder by the amount of dividends and distributions relating to the shares of excess stock which have been paid to the original transferee-shareholder and are owed by the original transferee-shareholder to the trustee. We may pay the amount of the reductions to the trustee for the benefit of the charitable beneficiary. The 90-day period begins on the later date of which notice is received of the violative transfer if the original transferee-shareholder gives notice to us of the transfer or, if no notice is given, the date the board of directors determines that a violative transfer has been made.

        These restrictions will not preclude settlement of transactions through the NYSE.

        All certificates representing shares of stock will bear a legend referring to the restrictions described above.

        Each shareholder shall upon demand be required to disclose to us in writing any information with respect to the direct, indirect and constructive ownership of capital stock of our company as the board of directors deems necessary to comply with the provisions of the Code applicable to REITs, to comply with the requirements of any taxing authority or governmental agency or to determine any such compliance.

        The Ownership Limit may have the effect of delaying, deferring or preventing a change in control of our company unless the board of directors determines that maintenance of REIT status is no longer in the best interest of our company.

HOW CAN I VOTE MY SHARES?

        We will send you proxy materials for any meeting of stockholders in order to vote all whole shares of common stock credited to your account. You may vote your shares of common stock either by designating the vote of the shares by proxy or by voting the shares in person at the meeting of stockholders.

19.

WHAT ARE THE COSTS OF THE PLAN?

        There are no fees or service charges on shares of common stock purchased from us for your account. We will pay per share processing fees on shares of common stock purchased on the open market for your account and, for tax purposes, these fees may be considered as additional taxable dividend income to you. We will pay all costs of administering the Plan, except as stated below. You will be responsible for any fees payable in connection with your sale of shares from the Plan. The Administrator will charge nominal fees for various services, including, but not limited to, sales of shares of common stock, preparing transcripts of accounts (in addition to normal monthly statements) and other special requests. These charges must be borne by you. Please see the "Plan Service Fees Schedule" attached as the Schedule hereto for a detailed description of the costs.

20.

WHAT ARE YOUR AND THE ADMINISTRATOR'S RESPONSIBILITIES?

        We, any of our agents and the Administrator, in administering the Plan, are not liable for any act done in good faith or for any good faith failure to act, including, without limitation, any claim of liability (i) arising from the failure to terminate your account upon your death or judgment of incompetence prior to the Administrator's receipt of notice in writing of the death; (ii) relating to the prices and times at which the Administrator buys or sells shares of common stock for your account; or (iii) relating to any fluctuation in the market value of the common stock.

        We, any of our agents and the Administrator will not have any duties, responsibilities or liabilities other than those expressly set forth in the Plan or as imposed by applicable laws, including federal securities laws. Since the Administrator has assumed all responsibility for administering the Plan, we specifically disclaim any responsibility for any of the Administrator's actions or inactions in connection with the administration of the Plan. None of our directors, officers or stockholders shall have any personal liability under the Plan.

21.

CAN I PLEDGE MY SHARES UNDER THE PLAN?

        You may not pledge any shares of common stock credited to your Plan account. Any attempted pledge will be void. If you wish to pledge your shares of common stock, you first must withdraw the shares from the Plan. See Question 15 to learn how to withdraw your shares under the Plan.

22.

HOW CAN I TRANSFER MY SHARES?

        In order to transfer shares, you will need to complete a Transfer Instruction Package. Simply visit the Administrator's website at www.computershare.com/investor to download the form or call the toll-free number to request a package. Please remember that you must obtain a Medallion Signature Guarantee for any transfer of shares.

        A Medallion Signature Guarantee ensures that the individual signing the request for transfer is the owner or authorized representative. It can be obtained from financial institutions (including many banks and brokerage firms) participating in one or more of the Medallion Signature Guarantee programs. For Book-to-book transfers, which involve transferring shares from an existing Plan account to a new Plan account, you should visit the Administrator's website at www.computershare.com/

CAN THE PLAN BE AMENDED, MODIFIED, SUSPENDED OR TERMINATED?

        Although we expect to continue the Plan indefinitely, we reserve the right to amend, modify, suspend or terminate the Plan in any manner at any time. We will notify you in writing of any modifications made to the Plan.

24.

WHAT HAPPENS IF WE TERMINATE THE PLAN?

        If we terminate the Plan, any whole shares of common stock held in your Plan account will be held on a book-entry account with the Administrator. A check representing the value of any fractional shares of common stock valued at the then current market price and any uninvested dividends or optional cash investments held in your account will be sent to you.

25.

ARE THERE ANY RISKS ASSOCIATED WITH THE PLAN?

        Your investment in shares of common stock purchased under the Plan is no different from any investment in shares of common stock that you hold directly. Neither we nor the Administrator can assure you a profit or protect you against a loss on shares that you purchase. You bear the risk of loss and enjoy the benefits of any gain from changes in the market price with respect to shares of common stock purchased under the Plan.

26.

HOW WILL YOU INTERPRET AND REGULATE THE PLAN?

        We may interpret, regulate and take any other action in connection with the Plan that we deem reasonably necessary to carry out the Plan. As a participant in the Plan, you will be bound by any actions taken by us or the Administrator.

27.

WHAT LAW GOVERNS THE PLAN?

        The laws of the State of Maryland will govern the terms, conditions and operation of the Plan.

28.

WHERE WILL NOTICES BE SENT?

USE OF PROCEEDS

        We will receive proceeds from the sale of common stock that the Administrator purchases directly from us. We will not receive proceeds from the sale of shares of common stock that the Administrator purchases in the open market or in privately negotiated transactions. We intend to contribute the net proceeds from the sale of shares of common stock offered hereby to SL Green Operating Partnership, L.P. (our "Operating Partnership"), which would use such net proceeds for general corporate purposes, which may include the repayment of existing indebtedness, the development or acquisition of additional properties (including through the acquisition of individual properties, portfolios and companies) as suitable opportunities arise and the renovation, expansion and improvement of our existing properties. We cannot estimate either the number of shares of common stock or the prices of the shares that we will sell in connection with the Plan.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

        The terms "we," "us" and "our" as such terms are used in the following summary refer to SL Green Realty Corp. unless the context requires otherwise. The term "U.S." as sometimes used in the following summary refers to United States.

        The following discussion summarizes the material United States federal income tax consequences that are generally applicable to prospective holders of SL Green common stock. The specific tax consequences of owning the offered securities will vary depending on the circumstances of a particular stockholder. The discussion contained herein does not address all aspects of federal income taxation that may be relevant to particular holders. Therefore, we strongly recommend that stockholders review the following discussion and then consult with a tax advisor to determine the anticipated tax consequences of owning the offered securities.

        The information in this section and the opinions of Greenberg Traurig, LLP are based on the Code, existing and proposed Treasury regulations thereunder, current administrative interpretations and court decisions. We cannot assume that future legislation, Treasury regulations, administrative interpretations and court decisions will not significantly change current law or affect existing interpretations of current law in a manner which is adverse to stockholders. Any such change could apply retroactively to transactions preceding the date of change. We cannot assume that the opinions and statements set forth herein, which do not bind the courts or the IRS, will not be challenged by the IRS or will be sustained by a court if so challenged.

        This summary does not discuss state, local or foreign tax consequences. Except where indicated, the discussion below describes general federal income tax consequences applicable to individuals who are U.S. persons for federal income tax purposes (as described below) and who hold the offered securities as "capital assets" within the meaning of Section 1221 of the Code. Accordingly, the following discussion has limited application to domestic corporations and persons subject to specialized federal income tax treatment, such as foreign persons, trusts, estates, tax-exempt entities, regulated investment companies and insurance companies.

        Under applicable Treasury regulations a provider of advice on specific issues of law is not considered an income tax return preparer unless the advice is (i) given with respect to events that have occurred at the time the advice is rendered and is not given with respect to the consequences of contemplated actions, and (ii) is directly relevant to the determination of an entry on a tax return. Accordingly, prospective stockholders should consult their respective tax advisors and tax return preparers regarding the preparation of any item on a tax return, even where the anticipated tax treatment has been discussed herein. In addition, prospective stockholders are urged to consult with their own tax advisors with regard to the application of the federal income tax laws to such stockholders' respective personal tax situations, as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction.

TAXATION OF THE COMPANY

        We elected to be taxed as a REIT under Sections 856 through 860 of the Code effective for our taxable year ended December 31, 1997. We believe that we have been organized and have operated, and we intend to continue to operate, in a manner to qualify as a REIT. In the opinion of Greenberg Traurig, LLP, commencing with our taxable year ended December 31, 2001, we have been organized and have been operated in conformity with the requirements for qualification and taxation as a REIT under the Code and our proposed method of operation will enable us to continue to meet the requirements for qualification and taxation as a REIT under the Code. This opinion is based on factual representations relating to the organization and operation of us, our Operating Partnership, our respective subsidiaries, factual representations relating to our continued efforts to comply with the various REIT tests and such documents that Greenberg Traurig, LLP has considered necessary or

29

Table of Contents

appropriate to review as a basis for rendering this opinion. Qualification and taxation as a REIT depends upon our ability to meet on a continuing basis, through actual annual operating results, the various qualification tests imposed under the Code. Greenberg Traurig, LLP will not review compliance with these tests on a continuing basis. See "Failure to Qualify" below.

        The following is a general summary of the material Code provisions that govern the federal income tax treatment of a REIT and its stockholders. These provisions of the Code are highly technical and complex.

        If we qualify for taxation as a REIT, we generally will not be subject to federal corporate income taxes on net income that we distribute currently to stockholders. This treatment substantially eliminates the double taxation (taxation at both the corporate and stockholder levels) that generally results from investment in a corporation.

        However, we will be subject to federal income and excise tax in specific circumstances, including the following:

•

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



•

we may be subject to the alternative minimum tax on our items of tax preference.



•

if we have (a) net income from the sale or other disposition of foreclosure property (which is, in general, property acquired by foreclosure or otherwise on default of a loan secured by the property) held primarily for sale to customers in the ordinary course of business or (b) other nonqualifying income from foreclosure property, we will be subject to tax at the highest corporate rate on such income.



•

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



•

if we fail to satisfy either the 75% gross income test or the 95% gross income test, but nonetheless maintain our qualification as a REIT because other requirements have been met, we will be subject to a 100% tax on (i) the greater of (a) the amount by which we fail the 75% test and (b) the amount by which we fail the 95% test, multiplied by (ii) a fraction intended to reflect our profitability.



•

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 years, we will be subject to a 4% excise tax on the excess of such required distribution over the amounts actually distributed.



•

if we fail to satisfy any of the REIT asset tests (other than a de minimis failure to meet the 5% or 10% asset test) due to reasonable cause and not due to willful neglect, and we nonetheless maintain our REIT qualification because of specified cure provisions, we will be required to pay a tax equal to the greater of $50,000 or the highest corporate tax rate multiplied by the net income generated during a certain period by the nonqualifying assets that caused us to fail such test.



•

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



•

if we acquire any asset from a corporation generally subject to full corporate level tax in a transaction in which the basis of the asset in our hands is determined by reference to the basis

30

---

Table of Contents

of the asset in the hands of the corporation and we recognize gain on the disposition of such asset during the ten-year period beginning on the date on which such asset was acquired by us, then we will be subject to the built-in gain rule. Built-in gain is the excess of the fair market value of such property at the time of acquisition by us over the adjusted basis in such property at such time. Under the built-in gain rule, we will be subject to tax on such gain at the highest regular corporate rate applicable.

•

if it is determined that amounts of certain income and expense were not allocated between us and a Taxable REIT Subsidiary (as defined herein) on the basis of arm's length dealing, or to the extent we charge a Taxable REIT Subsidiary interest in excess of a commercially reasonable rate, we will be subject to a tax equal to 100% of those amounts.



•

if we fail to comply with the requirement to send annual letters to our stockholders requesting information regarding the actual ownership of our shares, and the failure was not due to reasonable cause or to willful neglect, we will be required to pay a penalty of $25,000, or if the failure is intentional, a $50,000 penalty; and



•

certain of our subsidiaries are C corporations, the earnings of which will be subject to U.S. federal and state income tax.

REQUIREMENTS FOR QUALIFICATION

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

(a)

that is managed by one or more trustees or directors;



(b)

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



(c)

that would be taxable as a domestic corporation, but for Sections 856 through 859 of the Code;



(d)

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



(e)

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



(f)

during the last half of each taxable year not more than 50% in value of the outstanding stock of which is owned, directly or indirectly, by five or fewer individuals; and

that meets other tests, described below, regarding the nature of its income and assets. The Code provides that conditions (a) through (d), inclusive, must be met during the entire taxable year and that condition (e) must be met during at least 335 days of a taxable year of 12 months, or during a proportionate part of a taxable year of less than 12 months. Conditions (e) and (f), however, will not apply until after the first taxable year for which an election is made to be taxed as a REIT. We believe we have issued and have outstanding sufficient shares of stock with sufficient diversity of ownership to allow us to satisfy conditions (e) and (f). In addition, we intend to comply with Treasury regulations requiring us to ascertain the actual ownership of our outstanding shares. Our articles of incorporation include restrictions regarding the transfer of shares of capital stock that are intended to assist us in continuing to satisfy the share ownership requirements described in (e) and (f) above. See the discussion earlier in the answer to Question 17 under the caption "Terms and Conditions of the Plan."

        If a REIT owns a corporate subsidiary that is a qualified REIT subsidiary (generally, a corporation wholly owned by the REIT), that subsidiary is disregarded for federal income tax purposes and all assets, liabilities and items of income, deduction and credit of the subsidiary are treated as assets, liabilities and items of the REIT itself. Similarly, a single member limited liability company owned by

31

---

Table of Contents

the REIT or by the Operating Partnership is generally disregarded as a separate entity for federal income tax purposes.

        In the case of a REIT that is a partner in a partnership, Treasury regulations provide that for purposes of the gross income tests and asset tests, the REIT will be deemed to own its proportionate share, based on its interest in partnership capital, of the assets of the partnership and will be deemed to be entitled to the income of the partnership attributable to such share. In addition, the assets and gross income of the partnership will retain the same character in the hands of the REIT for purposes of Section 856 of the Code, including satisfying the gross income tests and asset tests, that they have in the hands of the partnership. Thus, our proportionate share of the assets, liabilities and items of gross income of the Operating Partnership will be treated as our assets, liabilities and items of gross income for purposes of applying the requirements described herein.

        Finally, a corporation may not elect to become a REIT unless its taxable year is the calendar year. Our taxable year is the calendar year.

        INCOME TESTS.    In order to maintain qualification as a REIT, we must annually satisfy two gross income tests. First, at least 75% of the REIT's gross income, excluding gross income from prohibited transactions, certain hedging transactions entered into after July 30, 2008, and certain foreign currency gains recognized after July 30, 2008, for each taxable year must be derived directly or indirectly from investments relating to real property or mortgages on real property, including rents from real property and, in specific circumstances, from certain types of temporary investments. Second, at least 95% of the REIT's gross income, excluding gross income from prohibited transactions, certain hedging transactions, and certain foreign currency gains recognized after July 30, 2008, for each taxable year must be derived from such real property investments described above and from dividends, interest and gain from the sale or disposition of stock or securities, or from any combination of the foregoing. If we fail to satisfy one or both of the 75% or the 95% gross income tests for any taxable year, we nevertheless may qualify as a REIT for such year if we are entitled to relief under specific provisions of the Code. These relief provisions generally are available if our failure to meet any such tests was due to reasonable cause and not due to willful neglect, we attach a schedule of the sources of our income to our federal corporate income tax return and any incorrect information on the schedule was not due to fraud with intent to evade tax. It is not possible, however, to state whether in all circumstances we would be entitled to the benefit of these relief provisions. As discussed above, even if these relief provisions were to apply, a tax would be imposed with respect to the non-qualifying gross income.

        For purposes of the income tests, rents received by a REIT will qualify as rents from real property only if the following conditions are met:

•

the amount of rent must not be based in whole or in part on the income or profits of any person. However, an amount received or accrued generally will not be excluded from rents from real property solely by reason of being based on a fixed percentage or percentages of receipts or sales;



•

rents received from a tenant generally will not qualify as rents from real property in satisfying the gross income tests if the REIT, or a direct or indirect owner of 10% or more of the REIT, directly or constructively, owns 10% or more of such tenant;



•

if rent attributable to personal property, leased in connection with a lease of real property, is greater than 15% of the total rent received under the lease, then the portion of rent attributable to such personal property will not qualify as rents from real property; and



•

the REIT generally must not operate or manage the property or furnish or render services to tenants, except through a Taxable REIT Subsidiary (as defined herein) or through an independent contractor who is adequately compensated and from whom the REIT derives no income.

32

---

Table of Contents

        The independent contractor requirement, however, does not apply to the extent the services provided by the REIT are usually or customarily rendered in connection with the rental of space for occupancy only and are not otherwise considered rendered to the occupant. Additionally, under the de minimis rule for noncustomary services, if the value of the noncustomary service income with respect to a property, valued at no less than 150% of the REIT's direct costs of performing such services, is 1% or less of the total income derived from the property, then the noncustomary service income will not cause other income from the property to fail to qualify as rents from real property (but the noncustomary service income itself will never qualify as rents from real property).

        We have received a favorable ruling from the IRS with respect to our provision of telecommunication services, including high-speed Internet access, to our tenants. Under the ruling, providing these services to a property will not disqualify rents received from the property. In addition, amounts that we receive for providing these services will constitute rents from real property.

        From time to time, we may enter into hedging transactions with respect to one or more of our assets or liabilities. Our hedging activities may include entering into interest rate swaps, caps, and floors, options to purchase these items, and futures and forward contracts. Income from a hedging transaction, including gain from the sale or disposition of such a transaction, that is clearly identified as a hedging transaction as specified in the Code will not constitute gross income and thus will be exempt from the 95% gross income test to the extent such a hedging transaction is entered into on or after January 1, 2005, and will not constitute gross income and thus will be exempt from the 75% gross income test as well as the 95% gross income test to the extent such hedging transaction is entered into after July 30, 2008. Income and gain from a hedging transaction, including gain from the sale or disposition of such a transaction, entered into on or prior to July 30, 2008 will be treated as nonqualifying income for purposes of the 75% gross income test. Income and gain from a hedging transaction, including gain from the sale or disposition of such a transaction, entered into prior to January 1, 2005 will be qualifying income for purposes of the 95% gross income test. The term "hedging transaction," as used above, generally means any transaction we enter into in the normal course of our business primarily to manage risk of (1) interest rate changes or fluctuations with respect to borrowings made or to be made by us to acquire or carry real estate assets, or (2) for hedging transactions entered into after July 30, 2008, currency fluctuations with respect to an item of qualifying income under the 75% or 95% gross income test. To the extent that we do not properly identify such transactions as hedges or we hedge with other types of financial instruments, the income from those transactions is not likely to be treated as qualifying income for purposes of the gross income tests. We intend to structure any hedging transactions in a manner that does not jeopardize our status as a REIT.

        PROHIBITED TRANSACTION INCOME.    Any gain that we realize (including any net foreign currency gain recognized after July 30, 2008) on the sale of property held as inventory or otherwise held primarily for sale to customers in the ordinary course of business (other than foreclosure property) will be treated as income from a prohibited transaction that is subject to a 100% penalty tax. This prohibited transaction income may also adversely affect our ability to satisfy the income tests for qualification as a REIT. Under existing law, whether property is held as inventory or primarily for sale to customers in the ordinary course of a trade or business is a question of fact that depends on all the facts and circumstances surrounding the particular transaction. We intend to hold our properties for investment with a view to long-term appreciation, to engage in the business of acquiring, developing and owning our properties and to make occasional sales of the properties as are consistent with our investment objectives. We do not intend to enter into any sales that are prohibited transactions. However, the IRS may successfully contend that some or all of our sales are prohibited transactions, and we would be required to pay the 100% penalty tax on the gains resulting from any such sales.

        PENALTY TAX.    Any redetermined rents, redetermined deductions or excess interest we generate will be subject to a 100% penalty tax. In general, redetermined rents are rents from real property that are overstated as a result of any services furnished to any of our tenants by one of our taxable REIT

33

Table of Contents

subsidiaries, and redetermined deductions and excess interest represent any amounts that are deducted by a taxable REIT subsidiary for amounts paid to us that are in excess of the amounts that would have been deducted based on arm's-length negotiations. Rents we receive will not constitute redetermined rents if they qualify for certain safe harbor provisions contained in the Code.

        From time to time our taxable REIT subsidiaries may provide services to our tenants. We intend to set any fees paid to our taxable REIT subsidiaries for such services at arm's-length rates, although the fees paid may not satisfy the safe-harbor provisions described above. These determinations are inherently factual, and the IRS has broad discretion to assert that amounts paid between related parties should be reallocated to clearly reflect their respective incomes. If the IRS successfully made such an assertion, we would be required to pay a 100% penalty tax on the excess of an arm's-length fee for tenant services over the amount actually paid.

        ASSET TESTS.    In order to maintain qualification as a REIT, we must also satisfy, at the close of each quarter of our taxable year, the following tests relating to the nature of our assets:

•

at least 75% of the value of our total assets must be represented by real estate assets, including (a) our allocable share of real estate assets held by the Operating Partnership or any partnerships in which the Operating Partnership owns an interest and (b) stock or debt instruments held for not more than one year purchased with the proceeds of a stock offering or long-term (i.e., at least five-year) public debt offering by us, cash, cash items and government securities;



•

no more than 25% of the value of our total assets may consist of securities other than those that qualify under the 75% test described above;



•

no more than 25% (20% for our taxable years beginning before January 1, 2009) of the value of our total assets may be securities of one or more Taxable REIT Subsidiaries; and



•

except for securities in the 75% asset class and securities of a Taxable REIT Subsidiary or a qualified REIT subsidiary: (a) the value of any one issuer's securities owned by us may not exceed 5% of the value of our total assets; (b) we may not own more than 10% of the total voting power of any one issuer's outstanding securities; and (c) we may not own more than 10% of the total value of any one issuer's outstanding securities (other than certain "straight debt" securities). We own in excess of 10% of the stock of a number of private REITs, each of which has elected to be taxed as a REIT for federal income tax purposes. As a REIT, each of these companies is subject to the various REIT qualification requirements. We believe that each of these companies has been organized and has operated in a manner to qualify for taxation as a REIT for federal income tax purposes and will continue to be organized and operated in this manner. If any of these companies were to fail to qualify as a REIT, our interest in the stock of such company could cease to be a qualifying real estate asset for purposes of the 75% asset test and could thus become subject to the 5% asset test, the 10% voting stock limitation and the 10% value limitation applicable to our ownership in corporations generally (other than REITs, qualified REIT subsidiaries and Taxable REIT Subsidiaries). As a result, we could fail to qualify as a REIT.

        A "Taxable REIT Subsidiary" is a corporation in which we own an interest that may earn income that would not be qualifying income if we earned it directly and may hold assets that would not be qualifying assets if we held them directly. We may hold up to 100% of the stock in a Taxable REIT Subsidiary. To treat a corporation as a Taxable REIT Subsidiary, we and the corporation must make a joint election by filing a Form 8875 with the IRS. A Taxable REIT Subsidiary will be liable for tax at corporate rates on any income it earns. Moreover, to prevent shifting of income and expenses between us and a Taxable REIT Subsidiary, the Code imposes on us a tax equal to 100% of certain items of income and expense that are not allocated between us and the Taxable REIT Subsidiary at arm's length

34

Table of Contents

(as described above). The 100% tax is also imposed to the extent we charge a Taxable REIT Subsidiary interest in excess of a commercially reasonable rate (as described above).

        After initially meeting an asset test at the close of any quarter, we will not lose our status as a REIT for failure to satisfy that asset test at the end of a later quarter solely by reason of changes in asset values (including, for tax years beginning after July 30, 2008, a discrepancy caused solely by the change in the foreign currency exchange rate used to value a foreign asset). If the failure to satisfy the asset test results from an acquisition of securities or other property during a quarter, the failure can be cured by disposition of sufficient nonqualifying assets within 30 days after the close of that quarter.

        Effective beginning with our 2005 taxable year, we would not lose our REIT status as the result of a failure to meet the 5% test, the 10% vote test or the 10% value test if the value of the assets causing the violation did not exceed the lesser of 1% of the value of our assets at the end of the quarter in which the violation occurred or $10,000,000 and we were to cure the violation by disposing of assets within six months of the end of the quarter in which we identified the failure. In addition, for a failure to meet the 5% test, the 10% vote test or the 10% value test that is larger than this amount, and for a failure to meet the 75% test, the 25% test, or the 25% (20% for our taxable years beginning before January 1, 2009) taxable REIT subsidiary asset test, we would not lose our REIT status if the failure were for reasonable cause and not due to willful neglect and we were to (i) file a schedule with the IRS describing the assets causing the violation, (ii) cure the violation by disposing of assets within six months of the end of the quarter in which we identified the failure and (iii) pay a tax equal to the greater of $50,000 or the product derived by multiplying the highest federal corporate income tax rate by the net income generated by the non-qualifying assets during the period of the failure. It is not possible, however, to state whether in all cases we would be entitled to these relief provisions.

        ANNUAL DISTRIBUTION REQUIREMENTS.    In order to qualify as a REIT, we are required to distribute dividends, other than capital gain dividends, to our stockholders in an amount at least equal to (a) the sum of (A) 90% of our REIT taxable income (computed without regard to the dividends paid deduction and our net capital gain) and (B) 90% of the net income, after tax, if any, from foreclosure property, minus (b) the sum of specific items of non-cash income. We must pay the distribution during the taxable year to which the distributions relate, or during the following taxable year, if declared before we timely file our tax return for the preceding year and paid on or before the first regular dividend payment after the declaration. In addition, a dividend declared and payable to a stockholder of record in October, November or December of any year may be treated as paid and received on December 31 of such year even if paid in January of the following year. To the extent that we do not distribute all of our net capital gain or distribute at least 90%, but less than 100%, of our REIT ordinary taxable income, we will be subject to tax on the undistributed amount at regular corporate capital gain and ordinary income rates, respectively. Furthermore, 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 income for such year and (c) any undistributed taxable income from prior periods, we will be subject to a 4% excise tax on the excess of such amounts over the amounts actually distributed.

        We intend to make timely distributions sufficient to satisfy the annual distribution requirements. In this regard, it is expected that our REIT taxable income will be less than our cash flow due to the allowance of depreciation and other non-cash charges in computing REIT taxable income. Moreover, the partnership agreement of the Operating Partnership authorizes us, as general partner, to take such steps as may be necessary to cause the Operating Partnership to make distributions to its partners in amounts sufficient to permit us to meet these distribution requirements. It is possible, however, that we may not have sufficient cash or other liquid assets to meet the 90% distribution requirement. In the event that such circumstances do occur, then in order to meet the 90% distribution requirement, we may cause the Operating Partnership to arrange for short-term, or possibly long-term, borrowings to permit the payment of required distributions.

Table of Contents

        The IRS recently issued a permanent revenue procedure that allows us to satisfy the REIT distribution requirements by making distributions partly in cash and partly in shares of our common stock, so long as we follow certain procedures. This follows a series of earlier temporary revenue procedures the IRS had issued to the same effect as well as two private rulings we had received from the IRS to the same effect. We have always paid all our dividends in the form of cash, other than dividends paid in stock pursuant to a dividend reinvestment plan, notwithstanding the earlier revenue procedures and our earlier private rulings. Nevertheless, we may pay a portion of dividends on our common stock with shares of our common stock in the future. The decision to authorize and pay dividends on our common stock in the future, as well as the timing, amount and composition of any such dividends, is at the sole discretion of our board of directors.

        Under specific circumstances, we may rectify a failure to meet the distribution requirement for a year by paying deficiency dividends to stockholders in a later year that may be included in our deduction for dividends paid for the earlier year. Thus, we may be able to avoid being taxed on amounts distributed as deficiency dividends. However, we would be required to pay to the IRS interest based upon the amount of any deduction taken for deficiency dividends.

FAILURE TO QUALIFY

        If we fail to qualify for taxation as a REIT in any taxable year and certain relief provisions do not apply, we will be subject to tax, including any applicable alternative minimum tax, on our taxable income at regular corporate rates. Distributions to stockholders in any year in which we fail to qualify as a REIT will not be deductible by us, nor will we be required to make distributions. Unless entitled to relief under specific statutory provisions, we also will be disqualified from taxation as a REIT for the four taxable years following the year during which qualification was lost. It is not possible to state whether in all circumstances we would be entitled to such statutory relief.

        Effective beginning with our 2005 taxable year, we would not lose our REIT status as the result of a failure to satisfy certain REIT requirements, such as requirements involving our organizational structure, if the failure was due to reasonable cause and not due to willful neglect and we were to pay a tax of $50,000. It is not possible, however, to state whether in all cases we would be entitled to this statutory relief.

OTHER TAX CONSIDERATIONS

        EFFECT OF TAX STATUS OF OUR OPERATING PARTNERSHIP AND OTHER ENTITIES ON REIT QUALIFICATION.    All of our significant investments are held through our Operating Partnership. Our Operating Partnership may hold interests in properties through property-owning entities. Our Operating Partnership and the property-owning entities involve special tax considerations. These tax considerations include:

•

allocations of income and expense items of our Operating Partnership and the property owning entities, which could affect the computation of our taxable income;



•

the status of our Operating Partnership and the property-owning entities as partnerships or entities that are disregarded as entities separate from their owners, as opposed to associations taxable as corporations, for income tax purposes; and



•

the taking of actions by our Operating Partnership or any of the property-owning entities that could adversely affect our qualification as a REIT.

        In the opinion of Greenberg Traurig, LLP, based on the factual representations by us and our Operating Partnership, for federal income tax purposes our Operating Partnership will be treated as a partnership and none of the property-owning entities (other than a Taxable REIT Subsidiary or an entity that is a REIT) will be treated as an association taxable as a corporation. If, however, our

36

---

Table of Contents

Operating Partnership or any of such other entities were treated as an association taxable as a corporation, we would fail to qualify as a REIT for a number of reasons.

        The partnership agreement requires that our Operating Partnership be operated in a manner that will enable us to satisfy the requirements for classification as a REIT. In this regard, we will control the operation of our Operating Partnership through our rights as the sole general partner of our Operating Partnership.

        TAX ALLOCATIONS WITH RESPECT TO THE PROPERTIES.    When property is contributed to a partnership in exchange for an interest in the partnership, the partnership generally takes a carryover basis in that property for tax purposes. Therefore, the partnership's basis is equal to the adjusted basis of the contributing partner in the property, rather than a basis equal to the fair market value of the property at the time of contribution. Pursuant to Section 704(c) of the Code, income, gain, loss and deductions attributable to such contributed property must be allocated in a manner such that the contributing partner is charged with, or benefits from, respectively, the unrealized gain or unrealized loss associated with the property at the time of the contribution. The amount of 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, which we refer to as 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. Our Operating Partnership has acquired properties in connection with its formation and subsequent thereto by way of contributions of appreciated property to our Operating Partnership in the transactions leading to its formation. Consequently, the partnership agreement requires these allocations to be made in a manner consistent with Section 704(c) of the Code and the Treasury regulations thereunder, which we refer to as the "Section 704(c) Regulations." The Section 704(c) Regulations require partnerships to use a "reasonable method" for allocation of items affected by Section 704(c) of the Code and they outline three methods which may be considered reasonable for these purposes. Our Operating Partnership generally uses the "traditional method" of Section 704(c) allocations, which is the least favorable method from our perspective because of technical limitations. Under the traditional method, depreciation with respect to a contributed property for which there is a Book-Tax Difference first will be allocated to us and other partners that did not have an interest in the property until they have been allocated an amount of depreciation equal to what they would have been allocated if our Operating Partnership had purchased such property for its fair market value at the time of contribution. In addition, if this property is sold, gain equal to the Book-Tax Difference at the time of sale will be specially allocated to the contributor of the property. These allocations tend to eliminate the Book-Tax Differences with respect to the contributed properties over the depreciable lives of the contributed property. However, they may not always entirely eliminate the Book-Tax Difference on an annual basis or with respect to a specific taxable transaction such as a sale. This could cause us (a) to be allocated lower depreciation deductions for tax purposes than would be allocated to us if all properties were to have a tax basis equal to their fair market value at the time of contribution and (b) to be allocated lower amounts of taxable loss in the event of a sale of interests in such contributed properties at a book loss, than the economic or book loss allocated to us as a result of such sale, with a corresponding benefit to the other partners in our Operating Partnership. These allocations might adversely affect our ability to comply with REIT distribution requirements, although we do not anticipate that this will occur. These allocations may also affect our earnings and profits for purposes of determining the portion of distributions taxable as dividend income. The application of these rules over time may result in a higher portion of distributions being taxed as dividends than would have occurred had we purchased our interests in the properties at their agreed values.

        Interests in the properties purchased by our Operating Partnership for cash will initially have a tax basis equal to their fair market values. Thus, Section 704(c) of the Code will not apply to such interests.

TAXATION OF STOCKHOLDERS

        This discussion does not address all of the tax consequences that may be relevant to particular stockholders in light of their particular circumstances. Stockholders should consult their own tax advisors for a complete description of the tax consequences of investing in our stock.

        As used herein, the term "U.S. Stockholder" means a stockholder who is a U.S. Person. A U.S. Person means any beneficial owner of our stock, other than an entity or arrangement treated as a partnership for U.S. federal income tax purposes, that is, for U.S. federal income tax purposes (i) a citizen or resident of the United States, (ii) a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source, (iv) a trust if (A) a court within the United States is able to exercise primary supervision over the administration of the trust and (B) one or more U.S. persons have the authority to control all substantial decisions of the trust, or (v) an eligible trust that elects to be taxed as a U.S. person under applicable Treasury Regulations.

        As used herein, the term "Non-U.S. Stockholder" means a beneficial owner of our stock, other than an entity or arrangement treated as a partnership for U.S. federal income tax purposes, that is not a U.S. Stockholder.

        If a partnership (including for this purpose any entity or arrangement treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of our common stock, the 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. A beneficial owner of our common stock that is a partnership and partners in such partnership should consult their tax advisors about the U.S. federal income tax consequences of owning and disposing of our common stock.

TAXATION OF U.S. STOCKHOLDERS

        DISTRIBUTIONS.    As long as we qualify as a REIT, distributions made to our taxable U.S. Stockholders out of current or accumulated earnings and profits and not designated as capital gain dividends will be taken into account by them as ordinary income. Corporate stockholders will not be eligible for the dividends received deduction as to such amounts. Earnings and profits are allocated to distributions with respect to preferred stock before they are allocated to distributions with respect to common stock. Distributions that are designated as capital gain dividends will be taxed as capital gains to the extent they do not exceed our actual net capital gain for the taxable year without regard to the period for which the stockholder has held our stock. If we elect to retain and pay income tax on any net capital gain, a U.S. Stockholder would include in its income as capital gain its proportionate share of such net capital gain. A U.S. Stockholder would also receive the right to claim a refundable tax credit for such stockholder's proportionate share of the tax paid by us on such retained capital gains and an increase in its basis in our stock. This increase in basis will be in an amount equal to the excess of the undistributed capital gains over the amount of tax paid thereon by us. Distributions in excess of current and accumulated earnings and profits will not be taxable to a U.S. Stockholder to the extent that they do not exceed the adjusted basis of the stock, but rather will reduce the adjusted basis of such U.S. Stockholder's stock. To the extent that such distributions exceed a U.S. Stockholder's adjusted basis in the stock, such distributions will be included in income as capital gain, assuming the stock is a capital asset in the hands of the stockholder.

        Any dividend declared by us in October, November or December of any year payable to a stockholder of record on a specific date in any such month shall be treated as both paid by us and received by the stockholder on December 31 of such year, provided the dividend is actually paid by us during January of the following calendar year.

        The IRS recently issued a permanent revenue procedure that allows us to satisfy the REIT distribution requirements by making distributions partly in cash and partly in shares of our common stock, so long as we follow certain procedures. This follows a series of earlier temporary revenue procedures the IRS had issued to the same effect as well as two private rulings we had received from the IRS to the same effect. We have always paid all our dividends in the form of cash, other than dividends paid in stock pursuant to a dividend reinvestment plan, notwithstanding the earlier revenue procedures and our earlier private rulings. Nevertheless, we may pay a portion of dividends on our common stock with shares of our common stock in the future. If we were to pay such a dividend, taxable U.S. Stockholders would be required to pay tax on the entire amount of the dividend, including the portion paid with shares of common stock, in which case such stockholders might have to pay the tax using cash from other sources. If a U.S. Stockholder sells the stock it receives as a dividend in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the dividend, depending on the market price of our stock at the time of the sale. The decision to authorize and pay dividends on our common stock in the future, as well as the timing, amount and composition of any such dividends, is at the sole discretion of our board of directors.

        SALE OR EXCHANGE.    In general, a taxable U.S. Stockholder recognizes capital gain or loss on the sale or exchange of our stock equal to the difference between (a) the amount of cash and the fair market value of any property received on such disposition, and (b) the stockholder's adjusted basis in the stock. To the extent a U.S. Stockholder who is an individual, a trust or an estate holds the stock for more than one year, any gain recognized would be subject to tax rates applicable to long-term capital gains. However, any loss recognized by a U.S. Stockholder from selling or otherwise disposing of our stock held for six months or less will be treated as long-term capital loss to the extent of dividends received by the stockholder that were required to be treated as long-term capital gains.

        TAX RATES.    For taxable years beginning after December 31, 2017, the highest tax rate on capital gains of non-corporate U.S. Stockholders and qualifying dividends to U.S. Stockholders is 20% and the highest marginal tax rate on ordinary income of individuals that are U.S. Stockholders is 37%. For additional information on federal tax rates, see "Material United States Federal Income Tax Consequences—Recent Legislation" below.

        Certain U.S. Stockholders who are individuals, estates or trusts are required to pay a 3.8% Medicare tax on, among other things, dividends on and capital gains from the sale or other disposition of our stock, subject to certain exceptions. U.S. Stockholders should consult their tax advisors regarding the effect, if any, of this tax on their ownership and disposition of our stock.

        We may be required to withhold a portion of capital gain distributions made to any stockholders who fail to certify their U.S. status to us.

        BACKUP WITHHOLDING.    We will report to our U.S. Stockholders and the IRS the amount of dividends paid during each calendar year and the amount of tax withheld, if any, with respect thereto. Under the backup withholding rules, a stockholder may be subject to backup withholding currently at a rate of 28% with respect to dividends paid unless the stockholder (a) is a corporation or comes within other exempt categories and, when required, demonstrates this fact, or (b) provides a taxpayer identification number and certifies with respect to certain matters and otherwise complies with the applicable requirements of the backup withholding rules. An individual who is a U.S. Stockholder may satisfy the requirements for avoiding backup withholding by providing us with an appropriately prepared IRS Form W-9. If a U.S. Stockholder does not provide us with its correct taxpayer identification number, then the U.S. Stockholder may also be subject to penalties imposed by the IRS.

        Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be refunded or credited against the U.S. Stockholder's federal income tax liability, provided the U.S. Stockholder timely furnishes the required information to the IRS.

TAXATION OF U.S. TAX-EXEMPT STOCKHOLDERS

        The IRS has ruled that amounts distributed as dividends by a REIT generally do not constitute unrelated business taxable income, or UBTI, when received by a U.S. tax-exempt entity. Based on that ruling, the dividend income from our stock will not be UBTI to a U.S. tax-exempt stockholder, provided that the U.S. tax-exempt stockholder has not held stock as debt financed property within the meaning of the Code and such stock is not otherwise used in a trade or business unrelated to the U.S. tax-exempt stockholder's exempt purpose. Similarly, income from the sale of the stock will not constitute UBTI unless such tax-exempt stockholder has held such stock as debt financed property within the meaning of the Code or has used the stock in a trade or business.

        Notwithstanding the above paragraph, if we are a pension-held REIT, then any qualified pension trust that holds more than 10% of our stock will have to treat dividends as UBTI in the same proportion that our gross income would be UBTI. A qualified pension trust is any trust described in Section 401(a) of the Code that is exempt from tax under Section 501(a) of the Code. In general, we will be treated as a pension-held REIT if both (a) we are predominantly owned by qualified pension trusts (i.e., if one such trust holds more than 25% of the value of our stock or one or more such trusts, each holding more than 10% of the value of our stock, collectively hold more than 50% of the value of our stock) and (b) we would not be a REIT if we had to treat our stock held by qualified pension trust as owned by the qualified pension trust (instead of treating such stock as owned by the qualified pension trust's multiple beneficiaries). Although we do not anticipate being classified as a pension-held REIT, we cannot assume that this will always be the case.

        In addition, if you are a tax-exempt stockholder described in Section 512(a)(3) of the Code, then distributions received from us may also constitute UBTI. You are described in Section 512(a)(3) of the Code if you qualify for exemption under Sections 501(c)(7), (9), (17), or (20) of the Code.

TAXATION OF NON-U.S. STOCKHOLDERS

        The rules governing the U.S. federal income taxation of a Non-U.S. Stockholder are complex and no attempt will be made herein to provide more than a summary of such rules. Non-U.S. Stockholders should consult with their own tax advisors to determine the impact of U.S. federal, state and local income tax laws with regard to an investment in our stock, including any reporting requirements.

        ORDINARY DIVIDENDS.    Distributions, other than distributions that are treated as attributable to gain from sales or exchanges by us of U.S. real property interests and other than distributions designated by us as capital gain dividends, will be treated as ordinary income to the extent that they are made out of our current or accumulated earnings and profits. Such distributions to Non-U.S. Stockholders will ordinarily be subject to a withholding of U.S. federal income tax equal to 30% of the gross amount of the distribution, unless an applicable tax treaty reduces that tax rate. However, if income from the investment in the shares of our stock is treated as effectively connected with the Non-U.S. Stockholder's conduct of a U.S. trade or business, the Non-U.S. Stockholder generally will be subject to a tax at graduated rates in the same manner as U.S. Stockholders are taxed with respect to such dividends and may also be subject to the 30% branch profits tax if the stockholder is a foreign corporation.

        The IRS recently issued a permanent revenue procedure that allows us to satisfy the REIT distribution requirements by making distributions partly in cash and partly in shares of our common stock, so long as we follow certain procedures. This follows a series of earlier temporary revenue procedures the IRS had issued to the same effect as well as two private rulings we had received from the IRS to the same effect. We have always paid all our dividends in the form of cash, other than dividends paid in stock pursuant to a dividend reinvestment plan, notwithstanding the earlier revenue procedures and our earlier private rulings. Nevertheless, we may pay a portion of dividends on our common stock with shares of our common stock in the future. If we were to pay such a dividend, we

40

Table of Contents

generally would be required to withhold U.S. federal income tax with respect to such dividends paid to Non U.S. Stockholders, including in respect of all or a portion of such dividend that is payable in stock. The decision to authorize and pay dividends on our common stock in the future, as well as the timing, amount and composition of any such dividends, is at the sole discretion of our board of directors.

        Dividends paid to an address in a country outside the United States are not presumed to be paid to a resident of such country for purposes of determining the applicability of withholding discussed above and the applicability of a tax treaty rate. A Non-U.S. Stockholder who wishes to claim the benefit of an applicable treaty rate generally will need to satisfy certification and other requirements, such as providing an IRS Form W-8BEN, or W-8BEN-E, as applicable. A Non-U.S. Stockholder, who wishes to claim that distributions are effectively connected with a United States trade or business, generally will need to satisfy certification and other requirements in order to avoid withholding, such as providing IRS Form W-8ECI. Other requirements may apply to Non-U.S. Stockholders that hold their shares through a financial intermediary or foreign partnership.

        RETURN OF CAPITAL.    Distributions in excess of our current and accumulated earnings and profits, which are not treated as attributable to the gain from the disposition by us of a U.S. real property interest, will not be taxable to a Non-U.S. Stockholder to the extent that they do not exceed the adjusted basis of our stock, but rather will reduce the adjusted basis of such stock. To the extent that such distributions exceed the adjusted basis of the stock, they will give rise to tax liability if the Non-U.S. Stockholder otherwise would be subject to tax on any gain from the sale or disposition of its stock, as described below. If it cannot be determined at the time a distribution is made whether such distribution will be in excess of current and accumulated earnings and profits, the distribution will be subject to withholding of U.S. federal income tax at the rate applicable to dividends. However, the Non-U.S. Stockholder may seek a refund of such amounts from the IRS to the extent it is subsequently determined that such distribution was, in fact, in excess of our current and accumulated earnings and profits.

        CAPITAL GAIN DIVIDENDS.    For any year in which we qualify as a REIT, distributions that are attributable to gain from sales or exchanges by us of U.S. real property interests will be taxed to a Non-U.S. Stockholder under the provisions of the Foreign Investment in Real Property Tax Act of 1980, as amended, or FIRPTA. Under FIRPTA, these distributions are taxed to a Non-U.S. Stockholder as if such gain were effectively connected with a U.S. business. Thus, Non-U.S. Stockholders will be taxed on such distributions at the same capital gain rates applicable to U.S. Stockholders, subject to any applicable alternative minimum tax and special alternative minimum tax (in the case of nonresident alien individuals), without regard to whether such distributions are designated by us as capital gain dividends. Also, distributions subject to FIRPTA may be subject to a 30% branch profits tax in the hands of a corporate Non-U.S. Stockholder not entitled to treaty relief or exemption. We are required by applicable Treasury Regulations under FIRPTA to withhold 21% of any distribution that could be designated by us as a capital gain dividend. However, capital gain dividends paid to a Non-U.S. Stockholder with respect to a class of REIT stock that is regularly traded on an established securities market in the United States will be treated as ordinary dividends, and not as capital gain dividends subject to FIRPTA, if the Non-U.S. Stockholder owns no more than 10% of the class of stock at any time during the one year period ending on the dividend payment date.

        SALE OR EXCHANGE OF STOCK.    Gain recognized by a Non-U.S. Stockholder upon a sale or exchange of stock, including a redemption that is treated as a sale, generally will not be taxed under the provisions of FIRPTA if we are a domestically controlled qualified investment entity. A REIT is a "domestically controlled qualified investment entity" if at all times during a specified testing period less than 50% in value of its stock is held directly or indirectly by non-U.S. persons. However, gain not subject to FIRPTA will be taxable to a Non-U.S. Stockholder if (a) investment in the stock is treated as effectively connected with the Non-U.S. Stockholder's U.S. trade or business, in which case the

41

Table of Contents

Non-U.S. Stockholder will be subject to the same treatment as U.S. Stockholders with respect to such gain, or (b) the Non-U.S. Stockholder is a nonresident alien individual who was present in the United States for 183 days or more during the taxable year (and certain other requirements are met), in which case the nonresident alien individual will be subject to a 30% tax on the individual's capital gains. A similar rule will apply to capital gain dividends not subject to FIRPTA.

        We will be a domestically controlled qualified investment entity if at all times during a specified testing period we are a REIT and less than 50% in value of our common stock is held, directly or indirectly, by non-U.S. persons. We believe that we currently are a domestically controlled qualified investment entity and, therefore, that the sale of our common stock would not be subject to taxation under FIRPTA. However, because our common stock is publicly traded, no assurance can be given that we are or will continue to be a domestically controlled qualified investment entity. If we were not a domestically controlled qualified investment entity, whether or not a Non-U.S. Stockholder's sale of stock would be subject to tax under FIRPTA would depend on whether or not the stock was regularly traded on an established securities market and on the size of the selling Non-U.S. Stockholder's interest in us. Currently, our stock is regularly traded on an established securities market. However, we cannot assure you that our stock will be so traded at the time you may wish to dispose of our stock. If the gain on the sale of the stock were to be subject to tax under FIRPTA, the Non-U.S. Stockholder would be subject to the same treatment as U.S. Stockholders with respect to such gain, subject to any applicable alternative minimum tax and a special alternative minimum tax (in the case of nonresident alien individuals) and the purchaser of such stock may be required to withhold 15% of the gross purchase price.

        BACKUP WITHHOLDING.    Backup withholding will not apply to payments made by us or our agent on stock to a Non-U.S. Stockholder if an IRS Form W-8BEN (or a suitable substitute form) is provided by such holder. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a Non-U.S. Stockholder may be refunded or credited against the Non-U.S. Stockholder's federal income tax liability, provided the Non-U.S. Stockholder furnishes the required information timely to the IRS.

        FOREIGN ACCOUNT TAX COMPLIANCE ACT.    The Foreign Account Tax Compliance Act, which is referred to herein as FATCA, was originally enacted in 2010. Based on recent IRS guidance, the FATCA rules currently impose a U.S. federal withholding tax of 30% on (i) interest, dividends, and certain other withholdable payments from U.S. sources made after June 30, 2014, and (ii) the gross proceeds from the disposition of any property of the type that can produce interest or dividends from U.S. sources occurring after December 31, 2018. FATCA withholding generally applies to the payments or proceeds paid to certain non-U.S. entities (including, in some circumstances, where such an entity is receiving payment as an intermediary) that fail to comply with certain certification and information reporting requirements. Prospective investors should consult their own tax advisors regarding the effect, if any, of the FATCA rules for them based on their particular circumstances.

TAX SHELTER REPORTING

        If a stockholder recognizes a loss with respect to the shares of (i) $2 million or more in a single taxable year or $4 million or more in a combination of taxable years, for a holder that is an individual, S corporation, trust or a partnership with at least one noncorporate partner, or (ii) $10 million or more in a single taxable year or $20 million or more in a combination of taxable years, for a holder that is either a corporation or a partnership with only corporate partners, the stockholder may be required to file a disclosure statement with the IRS on Form 8886. Direct stockholders of portfolio securities are in many cases exempt from this reporting requirement, but stockholders of a REIT currently are not exempt. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. Stockholders should consult

their tax advisors to determine the applicability of these regulations in light of their individual circumstances.

RECENT LEGISLATION

        On December 22, 2017, President Trump signed into law P.L. 115-97, informally titled the Tax Cuts and Jobs Act, or the Tax Act. The Tax Act makes major changes to the Code, including a number of provisions that affect the taxation of REITs and their stockholders.

        Certain provisions of the Tax Act that may impact us and our stockholders include:

•

temporarily reducing individual U.S. federal income tax rates on ordinary income; the highest individual U.S. federal income tax rate (excluding the 3.8% Medicare tax on net investment income) was reduced from 39.6% to 37% through taxable years ending in 2025;



•

reducing the maximum corporate U.S. federal income tax rate from 35% to 21%;



•

temporarily permitting a deduction for certain pass-through business income, including dividends received from REITs that are not designated as capital gain dividends or qualified dividend income, which generally will allow individuals, trusts, and estates to deduct up to 20% of such amounts, resulting in an effective maximum U.S. federal income tax rate of 29.6% on such dividends (excluding the 3.8% Medicare tax on net investment income) through taxable years ending in 2025;



•

reducing the highest rate of withholding with respect to distributions to non-U.S. stockholders that are treated as attributable to gains from the sale or exchange of U.S. real property interests from 35% to 21%;



•

limiting the deduction for net operating losses to 80% of taxable income (prior to the application of the dividends paid deduction);



•

interest deduction:



•

limiting the deductibility of "net interest" for a business, other than certain small businesses, to 30% of the business's adjusted taxable income (i.e., business taxable income computed without regard to business interest income or deductions, NOL deductions, any deduction for domestic production activities, and the new 20% deduction for qualified business income). Interest that is disallowed can be carried forward indefinitely.



•

exception for a "real property trade or business:" an electing "real property trade or business" may deduct 100% of its interest expense, in which case it would be required to use the less favorable alternative depreciation system to depreciate real property used in the trade or business. A "real estate trade or business" is any real property development, redevelopment, construction, reconstruction, acquisition, conversion, rental, operation, management, leasing or brokerage trade or business.



•

requiring an accrual method taxpayer to recognize income under the "all-events test" no later than the taxable year in which such income is taken into account as income on certain financial statements; and



•

eliminating the corporate alternative minimum tax.

        The individual and collective impact of these provisions and other provisions of the Tax Act on REITs and their stockholders is uncertain, and may not become evident for some period of time. Investors should consult with their tax advisors regarding the implications of the Tax Act on their particular circumstances (including the impact of other changes enacted as part of the Tax Act that do not directly relate to REITs and thus are not discussed here).

FEDERAL ESTATE TAXES

        In general, if an individual who is not a citizen or resident (as defined in the Code) of the United States owns (or is treated as owning) our stock at the date of death, such stock will be included in the individual's estate for U.S. federal estate tax purposes, unless an applicable estate tax treaty provides otherwise.

STATE AND LOCAL TAX

        We and our stockholders may be subject to state and local tax in states and localities in which we and/or they do does business or own property. Our tax treatment and the tax treatment of our stockholders in such jurisdictions may differ from the U.S. federal income tax treatment described above.

PLAN OF DISTRIBUTION

        Except to the extent the Administrator purchases shares of common stock in the open market or in privately negotiated transactions with third parties, we will sell directly to the Administrator the shares of common stock acquired under the Plan. The shares, including shares acquired pursuant to requests for waivers, may be resold in market transactions on any national securities exchange on which shares of common stock trade or in privately negotiated transactions. The shares of common stock currently are listed on the NYSE under the symbol "SLG."

        Persons who acquire shares of our common stock through the Plan and resell them shortly after acquiring them, including coverage of short positions, under certain circumstances, may be participating in a distribution of securities that would require compliance with Regulation M under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and may be considered to be underwriters within the meaning of the Securities Act of 1933, as amended. We will not extend to any such person any rights or privileges other than those to which he, she or it would be entitled as a participant, nor will we enter into any agreement with any such person regarding the resale or distribution by any such person of the shares of our common stock so purchased. We may, however, accept optional cash payments and initial investments made pursuant to requests for waivers by such persons.

        From time to time, financial intermediaries, including brokers and dealers, and other persons may engage in positioning transactions in order to benefit from any discounts applicable to optional cash payments and initial investments made under the Plan. Those transactions may cause fluctuations in the trading volume of our common stock. Financial intermediaries and such other persons who engage in positioning transactions may be deemed to be underwriters. We have no arrangements or understandings, formal or informal, with any person relating to the sale of shares of our common stock to be received under the Plan. We reserve the right to modify, suspend or terminate participation in the Plan by otherwise eligible persons to eliminate practices that are inconsistent with the purposes of the Plan.

        Subject to the availability of shares of common stock registered for issuance under the Plan, there is no total maximum number of shares that can be issued pursuant to the reinvestment of dividends and optional cash investments. We will pay all trading fees and service charges in connection with the reinvestment of dividends and optional cash investments to purchase common stock under the Plan. You will have to pay any fees payable in connection with your voluntary sale of shares from your Plan account and/or withdrawal from the Plan.

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 14.    OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

        The following table sets forth the estimated fees and expenses in connection with the issuance and distribution of the securities being registered hereby, which will be borne by the registrant. All amounts shown are estimates, except for the SEC registration fee:

ITEM 15.    INDEMNIFICATION OF DIRECTORS AND OFFICERS

        The Maryland General Corporation Law (the "MGCL") 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 which eliminates such liability to the maximum extent permitted by Maryland law. Our charter authorizes us, to the maximum extent permitted by Maryland law, to obligate ourselves to indemnify and to pay or reimburse reasonable expenses in advance of final disposition of a proceeding to (i) any present or former director or officer or (ii) any individual who, while a director or officer of our company and at the request of us, serves or has served another corporation, partnership, joint venture, trust, employee benefit plan or any other enterprise as a director, officer, partner or trustee of the corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. The bylaws of our company obligate it, to the maximum extent permitted by Maryland law, to indemnify and, and without requiring a preliminary determination of the ultimate entitlement to indemnification, to pay or reimburse reasonable expenses in advance of final disposition of a proceeding to (i) any present or former director or officer who is made a party to the proceeding by reason of his or her service in that capacity or (ii) any individual who, while a director of our company and at the request of us, serves or has served another corporation, partnership, joint venture, trust, employee benefit plan or any other enterprise as a director, officer, partner or trustee of the corporation, partnership, joint venture, trust, employee benefit plan or other enterprise and who is made a party to the proceeding by reason of his or her service in that capacity. The charter and bylaws also permit us to indemnify and advance expenses to any person who served a predecessor of our company in any of the capacities described above and to any employee or agent of our company or a predecessor of our company.

        The MGCL requires a corporation (unless its charter provides otherwise, which our charter does not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made a party by reason of his or her service in that capacity. The MGCL permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made a party by reason of their service in those or other capacities unless it is established that (i) the act or omission of the director or officer was material to the matter giving rise to the proceeding and (a) was committed in bad faith or (b) was the result of active and deliberate dishonesty, (ii) the director or officer actually received an improper personal benefit in money, property or services or (iii) in the case of any criminal proceeding,

II-1

---

Table of Contents

the director or officer had reasonable cause to believe that the act or omission was unlawful. However, a Maryland corporation may not indemnify for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on the basis that personal benefit was improperly received, unless ordered by a court and then only for expenses. In addition, the MGCL requires us, as a condition to advancing expenses, to obtain (i) a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary for indemnification by us as authorized by the bylaws and (ii) a written undertaking by or on his or her behalf to repay the amount paid or reimbursed by us if it shall ultimately be determined that the standard of conduct was not met.

        We have entered into indemnification agreements with each of our executive officers and directors. The indemnification agreements require, among other matters, that we indemnify our executive officers and directors to the fullest extent permitted by law and advance to the executive officers and directors all related expenses, subject to reimbursement if it is subsequently determined that indemnification is not permitted. Under these agreements, we must also indemnify and advance all expenses incurred by executive officers and directors seeking to enforce their rights under the indemnification agreements and may cover executive officers and directors under our directors' and officers' liability insurance. Although indemnification agreements offer substantially the same scope of coverage afforded by the bylaws, they provide greater assurance to directors and executive officers that indemnification will be available, because, as contracts, they cannot be modified unilaterally in the future by the board of directors or to eliminate the rights they provide.

ITEM 16.    EXHIBITS

ITEM 17.    UNDERTAKINGS

(a)

The undersigned registrant hereby undertakes:

(1)

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

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended;

II-2

---

Table of Contents

(ii)

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



(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(l)(i), (a)(l)(ii) and (a)(l)(iii) of this section do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2)

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



(3)

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



(4)

That, for the purpose of determining liability under the Securities Act of 1933, as amended, to any purchaser:



(i)

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and



(ii)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933, as amended, shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale

II-3

Table of Contents

prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5)

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



(i)

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



(ii)

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



(iii)

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



(iv)

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

(b)

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

(c)

Insofar as indemnification for liabilities arising under the Securities Act of 1933, as amended, may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933, as amended and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933, as amended and will be governed by the final adjudication of such issue.

(d)

The undersigned registrant hereby undertakes that:

(1)

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

(2)

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