PROSPECTUS SUPPLEMENT

(TO PROSPECTUS DATED SEPTEMBER 24, 2013)

1,400,000 Shares

Common Stock

We are offering 1,400,000 shares of common stock, par value $0.001 per share, in this offering.

Our common stock is traded on The NASDAQ Global Select Market under the symbol “GOOD.” The last reported sale price of our common stock on June 2, 2014, was $17.53 per share.

We believe that we qualify, and have elected to be taxed as, a real estate investment trust, or REIT, for federal income tax purposes. To assist us in complying with certain federal income tax requirements applicable to REITs, among other purposes, our charter contains certain restrictions relating to the ownership and transfer of our capital stock, including an ownership limit of 9.8% on shares of our capital stock by any person. See “Certain Provisions of Maryland Law and of our Charter and Bylaws—Restrictions on Ownership and Transfer” on page 23 of the accompanying prospectus for more information about these restrictions.

Investing in shares of our common stock involves substantial risks that are described in the “Risk Factors” sections beginning on page S-6 of this prospectus supplement, on page 17 of our Annual Report on Form 10-K for the year ended December 31, 2013 and other reports and information that we file from time to time with the Securities and Exchange Commission, or the SEC, which are incorporated by reference into this prospectus supplement and the accompanying prospectus.

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

The underwriters expect to deliver the shares of common stock on or about June 6, 2014. We have granted the underwriters an option for a period of 30 days from the date of this prospectus supplement to purchase an additional 210,000 shares of common stock. If the underwriters exercise the option in full, the total underwriting discounts and commissions payable by us will be $1,368,500, and the total proceeds to us, before expenses, will be $26,001,500.

FORWARD-LOOKING STATEMENTS

This prospectus supplement and the accompanying prospectus, including the documents incorporated by reference herein and therein, contain “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Also, documents we subsequently file with the SEC and incorporate by reference in this prospectus supplement and the accompanying prospectus may contain forward-looking statements. Forward-looking statements provide our current expectations or forecasts of future events and are not statements of historical fact. These forward-looking statements include information about possible or assumed future events, including, among other things, discussion and analysis of our future performance and financial condition, results of operations and funds from operations, or FFO, our strategic plans and objectives, cost management, occupancy and leasing rates and trends, liquidity and ability to refinance our indebtedness as it matures, anticipated capital expenditures (and access to capital) required to complete projects, amounts of anticipated cash distributions to our stockholders in the future and other matters. Words such as “anticipates,” “expects,” “intends,” “plans,” “believes,” “seeks,” “estimates” and variations of these words and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements will contain these words. These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control, are difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements. Statements regarding the following subjects, among others, are forward-looking by their nature:

Forward-looking statements involve inherent uncertainty and may ultimately prove to be incorrect or false. You are cautioned to not place undue reliance on forward-looking statements. Except as otherwise may be required by law, we undertake no obligation to update or revise forward-looking statements or update changed assumptions, the occurrence of unanticipated events or actual operating results. Our actual results could differ materially from those contained in these forward-looking statements as a result of various factors, including, but not limited to:

RISK FACTORS

Your investment in shares of our common stock involves substantial risks. In consultation with your own financial and legal advisers, you should carefully consider, among other matters, the factors set forth below, in our Annual Report on Form 10-K for the year ended December 31, 2013 and other reports and information that we file from time to time with the SEC, which are incorporated by reference into this prospectus supplement and the accompanying prospectus, before deciding whether an investment in shares of our common stock is suitable for you. If any of the risks contained in or incorporated by reference into this prospectus supplement or the accompanying prospectus develop into actual events, our business, financial condition, liquidity, results of operations, FFO, our ability to make cash distributions to holders of our common stock and prospects could be materially and adversely affected, the market price of our common stock could decline and you may lose all or part of your investment. In addition, new risks may emerge at any time and we cannot predict such risks or estimate the extent to which they may affect our financial performance. Some statements in this prospectus supplement, including statements in the following risk factors, constitute forward-looking statements. See the “Forward-Looking Statements” sections in this prospectus supplement and in the accompanying prospectus.

We have no immediate designated use for all of the net proceeds of this offering.

We intend to use the net proceeds from this offering to fund pending and future property acquisitions, repay existing indebtedness and for other general corporate purposes. We have not yet committed all of the net proceeds of this offering to investment in specific properties, and you will be unable to evaluate the economic merits of investments we make with the net proceeds before making an investment decision to purchase our common stock in this offering. As a result, we will have broad authority to invest the net proceeds of this offering in real estate investments that we may identify in the future, and we may use those proceeds to make investments with which you may not agree. In addition, our investment policies may be amended or revised from time to time at the discretion of our Board, without a vote of our stockholders. These factors increase the uncertainty, and thus the risk, of an investment in our common stock. Our failure to apply a substantial portion of the net proceeds of this offering effectively or to find suitable investments in a timely manner or on acceptable terms could result in returns that are substantially below expectations or result in losses.

This offering is expected to be dilutive, and there may be future dilution related to our common stock.

Giving effect to the issuance of shares of common stock in this offering, the receipt of the expected net proceeds and the use of those proceeds, we expect that this offering will have a dilutive effect on our expected earnings per share and FFO per share for the year ending December 31, 2014. The actual amount of dilution cannot be determined at this time and will be based upon numerous factors. Additionally, but subject to the 90-day lock-up restrictions described under the caption “Underwriting” in this prospectus supplement, we are not restricted from issuing additional securities, including common stock, senior common stock, preferred stock and securities that are convertible into or exchangeable for, or that represent the right to receive, common stock, senior common stock, preferred stock or any substantially similar securities. The market price of our common stock could decline as a result of issuances or sales of a large number of shares of our common stock in the market after this offering, or the perception that such issuances or sales could occur. Additionally, future issuances or sales of substantial amounts of our common stock, including those issued pursuant to our open market sale agreement with Jefferies LLC and shares of our senior common stock, may be at prices below the offering price of the common stock offered by this prospectus supplement and may result in further dilution in our earnings per share and FFO per share and adversely impact the market price of our common stock.

Securities eligible for future sale may have adverse effects on the share price of our common stock, and any additional capital raised by us through the sale of equity securities, including our senior common stock, may dilute your ownership in us.

In March 2011, we commenced a registered continuous public offering of up to 3,500,000 shares of our senior common stock. This continuous offering of senior common stock has been extended and is scheduled to terminate on the earlier of (i) March 28, 2015, or (ii) the date on which all remaining shares of senior common stock are sold pursuant to the Dealer Manager Agreement, dated March 25, 2011, between the Company and Gladstone Securities LLC, unless earlier terminated or extended by our Board of Directors. Following the fifth anniversary of the date of

S-6

Table of Contents

the original issuance of each share of senior common stock, each share of senior common stock will become exchangeable, at the holder’s option, for shares of our listed common stock. The exchange ratio will be calculated by dividing $15.00 (the value assigned to each share of senior common stock) by the greatest of (i) the closing trading price of listed common stock on the date on which such shares of senior common stock were originally issued, (ii) the book value per share of listed common stock as determined as of the date on which such shares of senior common stock were originally issued, or (iii) $13.68. The issuance of shares of our common stock in exchange for shares of senior common stock will dilute the voting power of the then holders of our common stock, may significantly dilute your ownership in us, and may create downward pressure on the market price of the common stock. As of May 30, 2014, we have sold a total of 362,437 shares of senior common stock pursuant to the offering.

As of May 30, 2014, we had the ability to raise up to $265.2 million of additional equity capital through the sale of securities that are registered under our universal shelf registration statement on Form S-3, or the Universal Shelf, in one or more future public offerings. Of the $265.2 million of available capacity under the Universal Shelf, approximately $3.2 million of common stock is reserved for additional sales under our open market sale agreement with Jefferies LLC and approximately $47.1 million is reserved for sales of our senior common stock. Sales of substantial amounts of our common stock or the perception that these sales could occur, may adversely affect the liquidity of our common stock or prevailing market prices for our common stock. Large price changes or low trading volume may preclude you from buying or selling our common stock at all, or at any particular price or during a time frame that meets your investment objectives.

Holders of our senior common stock and preferred stock and future holders of any securities ranking senior to our common stock have dividend and liquidation rights that are senior to the rights of the holders of our common stock.

As discussed above, in March 2011, we commenced a registered continuous public offering of shares of our senior common stock. Senior common stock is a separate class of our capital stock that has priority over listed common stock with respect to the payment of distributions. Senior common stock, however, is junior to our Series A Preferred, Series B Preferred and Series C Preferred with respect to the payment of distributions. Shares of our senior common stock are not listed or traded on a national securities exchange. Holders of shares of senior common stock will have the right, but not the obligation, following the fifth anniversary of the issuance of such shares to exchange any or all of such shares of senior common stock for shares of our listed common stock. Furthermore, in the event of our liquidation, each share of senior common stock will be automatically converted to a number of shares of our listed common stock in accordance with the applicable exchange ratio. Therefore, senior common stock will rank pari passu with our listed common stock upon a liquidation, dissolution or winding up of the Company.

In the future, we may attempt to increase our capital resources by making additional offerings of equity securities or issue debt securities. Upon liquidation, holders of our preferred stock, holders of our debt securities, if any, and lenders with respect to other borrowings, including our line of credit, would receive a distribution of our available assets in full prior to the holders of our common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our common stockholders bear the risk of our future offerings reducing the per share trading price of our common stock and diluting their interest in us.

The market price and trading volume of our common stock may fluctuate significantly.

The trading prices of equity securities issued by REITs historically have been affected by changes in market interest rates. One of the factors that may influence the price of our common stock is the annual yield from distributions on our common stock as compared to yields on other financial instruments. An increase in market interest rates, which may lead prospective purchasers of our common stock to demand a higher annual yield, or a decrease in our distributions to stockholders, could reduce the market price of our common stock.

Other factors that could significantly affect the market price of our common stock include the following:

S-7

Table of Contents

Many of the factors listed above are beyond our control. Those factors may cause the market price of our common stock to decline, regardless of our financial performance, condition and prospects. It is impossible to provide any assurance that the market price of our common stock will not decline in the future, and it may be difficult for our stockholders to resell their shares of our common stock at prices that they find attractive, or at all.

S-8

Table of Contents

USE OF PROCEEDS

We estimate that our net proceeds from this offering will be approximately $22.5 million (or approximately $25.9 million if the underwriters exercise their option to purchase additional shares in full) after deducting the underwriting discounts and commissions and other estimated offering expenses of approximately $0.1 million payable by us.

Through our Operating Partnership, we intend to use the net proceeds from this offering to fund pending and future property acquisitions, repay existing indebtedness and for other general corporate purposes.

Our line of credit matures in August 2017. The interest rate per annum applicable to the line of credit is equal to the London Interbank Offered Rate, or LIBOR, plus an applicable margin of up to 3.00%, depending upon our leverage. As of May 30, 2014, our line of credit had an outstanding balance of $44.5 million, which bears interest at an annual rate of approximately 3.2%. The maximum amount available to be drawn under our line of credit as of May 30, 2014 was $8.8 million.

Pending application of any portion of the net proceeds as described above, we may invest it in interest-bearing accounts and short-term, interest-bearing securities as is consistent with our intention to maintain our qualification as a REIT for federal income tax purposes. Such investments may include, for example, obligations of the Government National Mortgage Association, other government and governmental agency securities, certificates of deposit and interest-bearing bank deposits.

CAPITALIZATION

The following table sets forth our capitalization as of March 31, 2014 on an actual basis and on an as adjusted basis to reflect (i) the sale of 1,400,000 shares of our common stock offered by us in this offering after the deduction of the underwriting discounts and commissions and other estimated expenses payable by us and (ii) the application of the net proceeds as set forth under “Use of Proceeds.” The table does not give effect to the issuance of up to 210,000 additional shares of our common stock that may be sold pursuant to the underwriters’ option to purchase additional shares. The information set forth in the following table should be read in connection with, and is qualified in its entirety by reference to, the financial statements and notes thereto incorporated by reference in this prospectus supplement and the accompanying prospectus.

PRICE RANGE OF COMMON STOCK AND DISTRIBUTIONS

Our common stock is listed on The NASDAQ Global Select Market under the symbol “GOOD.” The following table reflects the range of the high and low sale prices of our common stock on The NASDAQ Global Select Market and the distributions per common share for each quarter in the years ended December 31, 2013 and 2012 and the current fiscal year through May 30, 2014. Distributions to our common stockholders are currently declared quarterly and paid monthly.

The decision as to whether to authorize and pay distributions on shares of our common stock in the future, as well as the timing, amount and composition of any such future distributions, will be at the sole and absolute discretion of our Board of Directors in light of conditions then existing, including our earnings, taxable income, FFO, financial condition, liquidity, capital requirements, debt maturities, the availability of capital, contractual prohibitions or other restrictions, applicable REIT and legal restrictions and general overall economic conditions and other factors. While the statements in this prospectus supplement concerning our distribution policy represent our current expectations, any actual distribution payable will be determined by our Board of Directors based upon the circumstances at the time of authorization and the actual number of shares of common stock then outstanding, and any future cash distribution payable on our common stock may vary from such expected amounts.

As of May 23, 2014, there were 13,869 beneficial holders of our shares of common stock. The transfer agent and registrar for our common stock is currently Computershare, Inc.

The Company pays distributions on shares of senior common stock in an amount equal to $1.05 per share per annum, declared daily and paid at the rate of $0.0875 per share per month. The Company’s senior common stock is not traded on any exchange or automated quotation system.

UNDERWRITING

Subject to the terms and conditions set forth in the underwriting agreement, dated June 3, 2014, by and among us, the Operating Partnership and Jefferies LLC, as representative of the underwriters named below, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the respective number of shares of common stock shown opposite its name below:

The underwriting agreement provides that the obligations of the several underwriters are subject to certain conditions precedent such as the receipt by the underwriters of officers’ and trustees’ certificates and legal opinions and approval of certain legal matters by their counsel. The underwriting agreement provides that the underwriters will purchase all of the shares of common stock if any of them are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated. We have agreed to indemnify the underwriters and certain of their controlling persons against certain liabilities, including liabilities under the Securities Act, and to contribute to payments that the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the shares of common stock subject to their acceptance of the shares of common stock from us and subject to prior sale. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commission and Expenses

The underwriters have advised us that they propose to offer the shares of common stock to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers, which may include the underwriters, at that price less a concession not in excess of $0.51 per share of common stock. After the offering, the public offering price and concession to dealers may be reduced by the representative. No such reduction will change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement.

The following table shows the public offering price, the underwriting discounts and commissions that we are to pay the underwriters and the proceeds, before expenses, to us in connection with this offering. Such amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

S-12

Table of Contents

We estimate expenses payable by us in connection with this offering, other than the underwriting discounts and commissions referred to above, will be approximately $100,000.

Listing

Our common stock is listed on The NASDAQ Global Select Market under the trading symbol “GOOD.”

Option to Purchase Additional Shares

We have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus supplement, to purchase, from time to time, in whole or in part, up to an aggregate of shares from us at the public offering price set forth on the cover page of this prospectus supplement, less underwriting discounts and commissions. If the underwriters exercise this option, each underwriter will be obligated, subject to specified conditions, to purchase a number of additional shares proportionate to that underwriter’s initial purchase commitment as indicated in the table above. This option may be exercised only if the underwriters sell more shares than the total number set forth on the cover page of this prospectus supplement.

No Sales of Similar Securities

We and our executive officers and directors have agreed, subject to specified exceptions, not to directly or indirectly, without the prior written consent of Jefferies LLC:

This restriction terminates after the close of trading of the common stock on and including the 90th day after the date of this prospectus supplement. However, subject to certain exceptions, in the event that either:

then in either case the expiration of the 90-day restricted period will be extended until the expiration of the 18-day period beginning on the date of the issuance of an earnings release or the occurrence of the material news or event, as applicable, unless Jefferies LLC waives, in writing, such an extension.

Jefferies LLC may, in its sole discretion and at any time or from time to time before the termination of the 90-day period, release all or any portion of the securities subject to lock-up agreements. There are no existing agreements between the underwriters and any of our stockholders who will execute a lock-up agreement, providing consent to the sale of shares prior to the expiration of the lock-up period.

Stabilization

The underwriters have advised us that they, pursuant to Regulation M under the Exchange Act, and certain persons participating in the offering, may engage in short sale transactions, stabilizing transactions, syndicate covering transactions or the imposition of penalty bids in connection with this offering. These activities may have the effect of stabilizing or maintaining the market price of the common stock at a level above that which might otherwise prevail in the open market. Establishing short sales positions may involve either “covered” short sales or “naked” short sales. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional shares of our common stock in this offering. The underwriters may close out any covered short position by either exercising their option to purchase additional shares of our common stock or purchasing shares of our

S-13

Table of Contents

common stock in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option to purchase additional shares.

“Naked” short sales are sales in excess of the underwriters’ option to purchase additional shares of our common stock. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the shares of our common stock in the open market after pricing that could adversely affect investors who purchase in this offering.

A stabilizing bid is a bid for the purchase of shares of common stock on behalf of the underwriters for the purpose of fixing or maintaining the price of the common stock. A syndicate covering transaction is the bid for or the purchase of shares of common stock on behalf of the underwriters to reduce a short position incurred by the underwriters in connection with the offering. Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. A penalty bid is an arrangement permitting the underwriters to reclaim the selling concession otherwise accruing to a syndicate member in connection with the offering if the common stock originally sold by such syndicate member are purchased in a syndicate covering transaction and therefore have not been effectively placed by such syndicate member.

Neither we, nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. The underwriters are not obligated to engage in these activities and, if commenced, any of the activities may be discontinued at any time.

The underwriters may also engage in passive market making transactions in our common stock on The NASDAQ Global Select Market in accordance with Rule 103 of Regulation M during a period before the commencement of offers or sales of shares of our common stock in this offering and extending through the completion of distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker’s bid, that bid must then be lowered when specified purchase limits are exceeded.

Electronic Distribution

A prospectus in electronic format may be made available by e-mail, on the web sites and/or through online services maintained by one or more of the underwriters or their affiliates. In those cases, prospective investors may view offering terms online and may be allowed to place orders online. The underwriters may agree with us to allocate a specific number of shares of common stock for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriters on the same basis as other allocations. Other than the prospectus in electronic format, the information on the underwriters’ web sites and any information contained in any other web site maintained by any of the underwriters is not part of this prospectus supplement or the accompanying prospectus, has not been approved and/or endorsed by us or the underwriters and should not be relied upon by investors.

THE COMPANY

We were incorporated as a Maryland corporation on February 14, 2003 primarily for the purpose of investing in and owning net leased industrial, commercial and retail real property and selectively making long-term industrial and commercial mortgage loans to creditworthy entities. Our portfolio of real estate is leased to a wide cross section of tenants ranging from small businesses to large public companies, many of which do not have publicly-rated debt. We have in the past entered into, and intend in the future to enter into, purchase agreements for real estate that have triple net leases with terms of 10 to 15 years and built in rental increases. Under a triple net lease, the tenant is required to pay all operating, maintenance and insurance costs and real estate taxes with respect to the leased property. We actively communicate with buyout funds, real estate brokers and other third parties to locate properties for potential acquisition or mortgage financing in an effort to build our portfolio.

Our business is managed by our external adviser, Gladstone Management Corporation, or our Adviser, which is an affiliated registered investment adviser under the Investment Advisers Act of 1940. Our Adviser is responsible for managing our business on a daily basis and for identifying and making acquisitions and dispositions that it believes satisfy our investment criteria.

We conduct substantially all of our activities, including the ownership of all of our properties, through our Operating Partnership. We control our Operating Partnership through our ownership of GCLP Business Trust II, a subsidiary of the Company and a Massachusetts business trust which holds the sole general partnership interest in our Operating Partnership, and of GCLP Business Trust I, a subsidiary of the Company and a Massachusetts business trust which holds all of the limited partnership interests of our Operating Partnership. Our Operating Partnership may issue limited partnership units from time to time in exchange for industrial and commercial real property. Limited partners who hold limited partnership units in our Operating Partnership will generally be entitled to redeem these units for cash or, at our election, shares of our common stock on a one-for-one basis.

The Operating Partnership is also the sole member of Gladstone Commercial Lending, LLC, a subsidiary of the Company and a Delaware limited liability company. Gladstone Commercial Lending, LLC was formed to conduct all operations related to our real estate mortgage loans.

Our executive offices are located at 1521 Westbranch Drive, Suite 200, McLean, Virginia 22102, and our telephone number is (703) 287-5800. Our website address is www.GladstoneCommercial.com. However, the information located on, or accessible from, our website is not, and shall not be deemed to be, a part of this prospectus, any accompanying prospectus supplement or any free writing prospectus or incorporated into any other filings that we make with the SEC.

RISK FACTORS

An investment in any securities offered pursuant to this prospectus involves substantial risks. You should carefully consider the risk factors incorporated by reference herein from our most recent Annual Report on Form 10-K, our subsequent Quarterly Reports on Form 10-Q and the other information contained in this prospectus, as updated, amended or superseded by our subsequent filings under the Exchange Act, and the risk factors and other information contained in any accompanying prospectus supplement before acquiring any of such securities. The occurrence of any of these risks could materially and adversely affect our business, prospects, financial condition, results of operations and cash flow and might cause you to lose all or part of your investment in the offered securities. Much of the business information, as well as the financial and operational data contained in our risk factors, is updated in our periodic reports filed with the SEC pursuant to the Exchange Act, which are also incorporated by reference into this prospectus. Although we have tried to discuss key risk factors, please be aware that these are not the only risks we face and there may be additional risks that we do not presently know of or that we currently consider not likely to have a significant impact. New risks may emerge at

any time and we cannot predict such risks or estimate the extent to which they may affect our business or our financial performance. Please also refer to the section entitled “Forward-Looking Statements” above.

RATIO OF EARNINGS TO FIXED CHARGES AND PREFERRED DIVIDENDS

Our ratios of earnings to fixed charges and preferred dividends for the six months ended June 30, 2013 and the years ended December 31, 2012, 2011, 2010, 2009 and 2008 are set forth below. For purposes of calculating the ratio of earnings to fixed charges and preferred dividends, “earnings” consist of net income from continuing operations before fixed charges. “Fixed charges” consist of interest expense, amortization of deferred financing fees and the portion of operating lease expense that represents interest.

USE OF PROCEEDS

Unless we specify otherwise in an accompanying prospectus supplement, we intend to use the net proceeds from the issuance or sale of our securities to provide additional funds for general corporate purposes, which may include, without limitation, the repayment of outstanding indebtedness, the acquisition of additional properties, capital expenditures and/or improvements to properties in our portfolio, distributions to stockholders and working capital. Any specific allocation of the net proceeds of an offering of securities to a specific purpose will be determined at the time of such offering and will be described in the accompanying prospectus supplement to this prospectus.

DESCRIPTION OF CAPITAL STOCK

General

Our authorized capital stock consists of 50,000,000 shares of capital stock, $0.001 par value per share, 38,500,000 of which are classified as common stock, 1,150,000 of which are classified as 7.75% Series A Cumulative Redeemable Preferred Stock, 1,150,000 of which are classified as 7.50% Series B Cumulative Redeemable Preferred Stock, 1,700,000 of which are classified as 7.125% Series C Cumulative Term Preferred Stock and 7,500,000 of which are classified as senior common stock. Under our charter, our board of directors is authorized to classify and reclassify any unissued shares of capital stock by setting or changing in any one or more respects, from time to time before issuance of such stock, the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms and conditions of redemption of such stock. Our board of directors may also, without stockholder approval, amend our charter from time to time to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class that we have authority to issue.

For purposes of this section “Description of Capital Stock,” we refer to our common stock which is listed on the NASDAQ Global Select Market under the symbol “GOOD” as our “Listed Common Stock.” Further, we refer to our (i) 7.75% Series A Cumulative Redeemable Preferred Stock, which is listed on the NASDAQ Global Select Market under the symbol “GOODP,” as our “Series A Preferred Stock”, our (ii) 7.50% Series B

Table of Contents

Cumulative Redeemable Preferred Stock, which is listed on the NASDAQ Global Select Market under the symbol “GOODO,” as our “Series B Preferred Stock” our (iii) 7.125% Series C Cumulative Term Preferred Stock, which is listed on the NASDAQ Global Select Market under the symbol “GOODN,” as our “Series C Preferred Stock” and our (iv) non-listed senior common stock, as our “Senior Common Stock.” We collectively refer to our Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock as our “Preferred Stock” where appropriate.

The following summary description of our capital stock is not necessarily complete and is qualified in its entirety by reference to our charter and bylaws, each of which has been filed with the SEC, as well as applicable provisions of the Maryland General Corporation Law, or the MGCL.

Meetings and Special Voting Requirements

An annual meeting of the stockholders will be held each year for the purpose of electing the class of directors whose term is up for election and to conduct other business that may be properly brought before the stockholders. Special meetings of stockholders may be called only upon the request of a majority of our directors, a majority of our independent directors, our chairman, our chief executive officer or our president and must be called by our secretary upon the written request of stockholders entitled to cast at least a majority of all the votes entitled to be cast at a meeting. In general, the presence in person or by proxy of a majority of the outstanding shares, exclusive of excess shares (described in “Certain Provisions of Maryland Law and of Our Charter and Bylaws — Restrictions on Ownership of Shares,” below), shall constitute a quorum. Generally, the affirmative vote of a majority of the votes cast at a meeting at which a quorum is present is necessary to take stockholder action, except that a plurality of all votes cast at such a meeting is sufficient to elect any director.

Under Maryland law, a Maryland corporation generally cannot dissolve, amend its charter, merge, sell all or substantially all of its assets, engage in a share exchange or engage in similar transactions outside the ordinary course of business, unless approved by the affirmative vote of stockholders entitled to cast at least two-thirds of the votes entitled to be cast on the matter. However, a Maryland corporation may provide in its charter for approval of these matters by a lesser percentage, but not less than a majority of all of the votes entitled to be cast on the matter. Our charter provides for a majority vote in these situations.

Stockholders may, by the affirmative vote of at least two-thirds of all votes entitled to be cast generally in the election of directors, elect to remove a director for cause. Stockholders do not have the ability to vote to replace our Adviser or to select a new adviser.

Repurchases of Excess Shares

We have the authority to redeem “excess shares” (as defined in our charter) immediately upon becoming aware of the existence of excess shares or after giving the holder of the excess shares 30 days to transfer the excess shares to a person whose ownership of such shares would not exceed the ownership limit, and therefore such shares would no longer be considered excess shares. The price paid upon redemption by us shall be the lesser of the price paid for such excess shares by the stockholder holding the excess shares or the fair market value of the excess shares, see “Certain Provisions of Maryland Law and of Our Charter and Bylaws — Restrictions on Ownership of Shares.”

Common Stock

Certificates

Generally, we will not issue stock certificates. Shares of common stock will be held in “uncertificated” form, which will eliminate the physical handling and safekeeping responsibilities inherent in owning transferable

5

Table of Contents

stock certificates and eliminate the need to return a duly executed stock certificate to the transfer agent to effect a transfer. Transfers can be effected simply by mailing to us a duly executed transfer form. Upon the issuance of shares of common stock, we will send to each stockholder a written statement which will include all information that is required to be written upon stock certificates pursuant to the MGCL.

Other Matters

The transfer and distribution paying agent and registrar for our common stock is Computershare Shareowner Services.

Listed Common Stock

Voting Rights

Each share of Listed Common Stock is entitled to one vote on each matter to be voted upon by our stockholders, including the election of directors, and, except as provided with respect to any other class or series of capital stock, the holders of the Listed Common Stock possess exclusive voting power. There is no cumulative voting in the election of directors which means that the holders of a majority of the outstanding Listed Common Stock can elect all of the directors then standing for election and that the holders of the remaining shares are not able to elect any directors.

Dividends, Liquidations and Other Rights

Holders of Listed Common Stock are entitled to receive distributions, when authorized by our board of directors and declared by us, out of assets legally available for the payment of distributions. We pay distributions on the Listed Common Stock on a monthly basis. They also are entitled to share ratably in our assets legally available for distribution to our stockholders in the event of our liquidation, dissolution or winding up, after payment of or adequate provision for all of our known debts and liabilities. These rights are subject to the preferential rights of any other class or series of our shares, including the Senior Common Stock, and our Preferred Stock and the provisions of our charter regarding restrictions on transfer and ownership of shares of our capital stock.

Holders of our Listed Common Stock have no preference, conversion, exchange, sinking fund, redemption or appraisal rights and have no preemptive rights to subscribe for any of our securities. Subject to the restrictions on transfer and ownership of shares of our capital stock contained in our charter, all shares of Listed Common Stock have equal distribution, liquidation and other rights.

Senior Common Stock

Voting Rights

Holders of our Senior Common Stock have no voting rights, except as set forth below or as otherwise from time to time required by law. So long as any shares of Senior Common Stock remain outstanding, we will not, without the affirmative vote or consent of the holders of at least a majority of the shares of the Senior Common Stock outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting separately by class), amend, alter or repeal the provisions of our charter, whether by merger, consolidation or otherwise, so as to materially and adversely affect any right, preference, privilege or voting power of the Senior Common Stock or the holders thereof.

Dividends, Liquidations and Other Rights

The Senior Common Stock has priority over the Listed Common Stock with respect to payment of distributions and is pari passu with the Listed Common Stock with respect to distribution of amounts upon

6

Table of Contents

liquidation, dissolution or winding up; however, the Senior Common Stock ranks junior to our Preferred Stock with respect to payment of distributions and distribution of amounts upon liquidation, dissolution or winding up. The Senior Common Stock will be entitled to receive, subject to the preferential rights of our Preferred Stock (and any other preferred stock that we may issue in the future), when and as authorized by our board of directors and declared by us, out of funds legally available for payment of distributions, cash distributions in an amount equal to $1.05 per share per annum, declared daily and paid at the rate of $0.0875 per share per month. Distributions are cumulative from the date of issue of the shares and are payable monthly on or about the 5th business day of the month following the month in which such distributions are earned.

Exchange Option

Holders of Senior Common Stock have the right, but not the obligation, after the 5th anniversary of the issuance of the shares of Senior Common Stock proposed to be exchanged, to exchange any or all of such shares of Senior Common Stock for our Listed Common Stock at a predetermined exchange ratio, or the Exchange Ratio. The Exchange Ratio will be calculated by dividing $15.00 by the greatest of (i) the Closing Trading Price of the Listed Common Stock on the date on which such shares of Senior Common Stock were originally issued, (ii) the Book Value Per Share of the Listed Common Stock as determined as of the date on which such shares of Senior Common Stock were originally issued, and (iii) $13.68. For this purpose, “Book Value Per Share” means, as of a given date, the common stockholders’ equity (as reflected in our most recent public filing with the SEC) divided by the number of outstanding shares of common stock as of the same date. “Closing Trading Price” means, on any date of determination, (i) the most recently reported closing price per share of the Listed Common Stock as of such date on the NASDAQ Global Select Market, or (ii) if, as of such date, the Listed Common Stock is not traded on the NASDAQ Global Select Market, the most recently reported closing price per share of the Listed Common Stock on the primary stock exchange on which the Listed Common Stock is then listed for trading, or (iii) if, as of such date, the Listed Common Stock is not listed for trading on any stock exchange, the closing bid price for the Listed Common Stock on the Over-the-Counter Bulletin Board, or (iv) if neither (i), (ii) or (iii) apply, the last reported bid price on the over-the-counter market or on the Pink Sheets, or (v) if there is no longer any public market for the Listed Common Stock as of such date, the fair market value of a share of Listed Common Stock as determined in good faith by our board of directors.

Solely for purposes of determining when shares of Senior Common Stock become exchangeable, shares of Senior Common Stock purchased by a holder on dates subsequent to such holder’s initial purchase of Senior Common Stock (excluding shares issued pursuant to such holder’s participation in a distribution reinvestment plan of the Company, if any) will be deemed to have been issued on their respective issuance dates and, accordingly, the 5-year holding periods for such shares will commence from their respective issuance dates. In addition, any shares issued pursuant to a distribution reinvestment plan of the Company, if any, will be deemed to have been issued, and the five-year holding periods for such shares will be deemed to commence, on the date of issuance of the shares of Senior Common Stock purchased by the holder to which the shares issued pursuant to such Company’s distribution reinvestment plan relate.

All accumulated and unpaid distributions on the Senior Common Stock shall be paid to the holder through the date of exchange.

Automatic Conversion

Each share of Senior Common Stock will be converted into Listed Common Stock in accordance with the Exchange Ratio automatically upon any of the following events:

7

Table of Contents

All accumulated and unpaid distributions on the Senior Common Stock shall be paid to the holder through the date of conversion.

Call Protection

Shares of Senior Common Stock will be callable at our sole option on or after September 1, 2017. At such time the shares of Senior Common Stock will be callable for cash at our option, in whole or in part, at a redemption price equivalent to $15.30 per share, plus accrued and unpaid distributions. We may not call shares of Senior Common Stock prior to September 1, 2017, except in certain limited circumstances relating to maintaining our ability to qualify as a real estate investment trust, or REIT.

Anti-Dilution

If the outstanding Listed Common Stock is increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company or of any other company by reason of any reclassification, recapitalization, share split up, combination of shares, or share distribution, appropriate adjustment will be made to the number of shares and relative terms of the Senior Common Stock. There will be no anti-dilution adjustment upon the future sale of additional shares of Listed Common Stock, regardless of the price at which the Senior Common Stock is sold.

Valuation

Beginning with the quarter ending September 30, 2014, we will determine the value of the Senior Common Stock on a quarterly basis. This value will be determined as of the last day of each quarter and will be posted to our website at www.GladstoneCommercial.info.

Preferred Stock

General

Subject to limitations prescribed by the MGCL and our charter, our board of directors is authorized to issue, from the authorized but unissued shares of stock, shares of preferred stock in class or series and to establish from time to time the number of shares of preferred stock to be included in the class or series and to fix the designation and any preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends and other distributions, qualifications and terms and conditions of redemption of the shares of each class or series.

In addition, we may not amend the charter, including the designations, rights, preferences, privileges or limitations in respect of the Series A Preferred Stock, in a manner that would materially and adversely affect the rights, preferences, privileges or voting powers of the Series A Preferred Stock or the holders thereof without the affirmative vote of the holders of at least two-thirds of the shares of Series A Preferred Stock then outstanding.

Effective January 30, 2011, we have the ability, at our sole option, to redeem the Series A Preferred Stock, in whole or in part, at any time or from time to time, by payment of $25.00 per share, plus any accumulated and unpaid dividends to the date of redemption.

In addition, if we fail to redeem or call for redemption the Series C Preferred Stock pursuant to the mandatory redemption required on January 31, 2017, the holders of the Series C Preferred, as a class, to the exclusion of the holders of all other classes of our stock, will be entitled to elect a majority of our directors until all shares of Series C Preferred Stock are redeemed or called for redemption. Further, we may not amend the charter, including the designations, rights, preferences, privileges or limitations in respect of the Series C Preferred Stock, in a manner that would materially and adversely affect the rights, preferences, privileges or voting powers of the Series C Preferred Stock or the holders thereof without the affirmative vote of the holders of at least two-thirds of the shares of Series C Preferred Stock then outstanding.

Dividends, Liquidation Preference and Other Rights

Holders of Series C Preferred Stock are entitled to receive, when and as authorized by our Board and declared by us, preferential cumulative cash dividends on the Series C Preferred Stock at a rate of 7.125% per annum of the $25.00 per share liquidation preference (equivalent to $1.7813 per annum per share). Beginning on the date of issuance, dividends on the Series C Preferred Stock are payable monthly in arrears and are cumulative.

10

Table of Contents

If we liquidate, dissolve or wind up, holders of the Series C Preferred Stock will have the right to receive the $25.00 per share liquidation preference, plus any accumulated and unpaid dividends to and including the date of payment, but without interest, before any payment is made to the holders of our common stock (including our Listed Common Stock and Senior Common Stock) or any other class or series of our capital stock ranking junior to the Series C Preferred Stock as to liquidation rights.

With respect to the payment of dividends and amounts upon liquidation, dissolution or winding up, the Series C Preferred Stock will be equal in rank with our Series A Preferred Stock, Series B Preferred Stock and all other equity securities we issue, the terms of which specifically provide that such equity securities rank on a parity with the Series C Preferred Stock with respect to dividend rights or rights upon our liquidation, dissolution or winding up; senior to our common stock (including our Listed Common Stock and Senior Common Stock); and junior to all our existing and future indebtedness.

We may not redeem the Series C Preferred Stock prior to January 31, 2016, except in limited circumstances relating to our continuing qualification as a REIT. On and after January 31, 2016 and before January 31, 2017, we may, at our option, redeem the Series C Preferred Stock, in whole or in part, at any time or from time to time, by payment of $25.00 per share, plus any accumulated and unpaid dividends to and including the date of redemption. If not redeemed earlier, the Series C Preferred Stock has a mandatory redemption date of January 31, 2017.

Shares of Series C Preferred Stock are not convertible into or exchangeable for any other securities or property.

Future Classes or Series of Preferred Stock

The following description of the terms of our preferred stock sets forth general terms and provisions of our preferred stock to which an accompanying prospectus supplement may relate. Specific terms of any class or series of preferred stock offered by an accompanying prospectus supplement will be described in that prospectus supplement. The description set forth below is subject to and qualified in its entirety by reference to the articles supplementary to our charter fixing the preferences, conversion or other rights, voting powers, restrictions, limitations as to dividends or other distributions, qualifications and terms and conditions of redemption of a particular class or series of preferred stock.

If we offer preferred stock pursuant to this prospectus, an accompanying prospectus supplement will describe the specific terms of the class or series of shares of preferred stock being offered, including, but not limited to:

11

Table of Contents

If we issue shares of preferred stock under this prospectus, the shares will be fully paid and non-assessable and will not have, or be subject to, any preemptive or similar rights.

The issuance of preferred stock could adversely affect the voting power, conversion or other rights of holders of common stock. Preferred stock could be issued quickly with terms designed to delay or prevent a change in control of our company or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our common stock.

Restrictions on ownership and transfer of our common stock and Preferred Stock are designed to preserve our status as a REIT, among other purposes, and, therefore, may act to prevent or hinder a change of control. See “Certain Provisions of Maryland Law and of Our Charter And Bylaws — Restrictions on Ownership and Transfer” below.

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities under one or more trust indentures to be executed by us and a specified trustee. The terms of the debt securities will include those stated in the indenture and those made a part of the indenture by reference to the Trust Indenture Act of 1939, or the Trust Indenture Act. The indentures will be qualified under the Trust Indenture Act.

12

Table of Contents

The following description sets forth certain anticipated general terms and provisions of the debt securities to which an accompanying prospectus supplement may relate. The particular terms of the debt securities offered by an accompanying prospectus supplement (which terms may be different than those stated below) and the extent, if any, to which such general provisions may apply to the debt securities so offered will be described in the prospectus supplement relating to such debt securities. Accordingly, for a description of the terms of a particular issue of debt securities, investors should review both the accompanying prospectus supplement relating thereto and the following description. A form of the indenture (as discussed herein) has been filed as an exhibit to the registration statement of which this prospectus is a part.

The debt securities will be our direct obligations and may be either senior debt securities or subordinated debt securities. The indebtedness represented by subordinated securities will be subordinated in right of payment to the prior payment in full of our senior debt (as defined in the applicable indenture).

Except as set forth in the applicable indenture and described in an accompanying prospectus supplement relating thereto, the debt securities may be issued without limit as to aggregate principal amount, in one or more series, secured or unsecured, in each case as established from time to time in or pursuant to authority granted by a resolution of the board of directors or as established in the applicable indenture. All debt securities of one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of the holders of the debt securities of such series, for issuance of additional debt securities of such series.

The accompanying prospectus supplement relating to any series of debt securities being offered will contain their specific terms, including, without limitation:

13

Table of Contents

The debt securities may provide for less than the entire principal amount thereof to be payable upon declaration of acceleration of the maturity thereof. Special federal income tax, accounting and other considerations applicable to debt securities will be described in the accompanying prospectus supplement.

The applicable indenture may contain provisions that would limit our ability to incur indebtedness or that would afford holders of debt securities protection in the event of a highly leveraged or similar transaction involving us or in the event of a change of control.

Merger, Consolidation or Sale

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

14

Table of Contents

Covenants

The applicable indenture will contain covenants requiring us to take certain actions and prohibiting us from taking certain actions. The covenants with respect to any series of debt securities will be described in the accompanying prospectus supplement.

Events of Default, Notice and Waiver

Each indenture will describe specific “events of default” with respect to a series of debt securities issued under the indenture. These “events of default” are likely to include (with grace and cure periods):

If an event of default under any indenture with respect to debt securities of any series at the time outstanding occurs and is continuing, then the applicable trustee or the holders of not less than 25% of the principal amount of the outstanding debt securities of that series may declare the principal amount (or, if the debt securities of that series are original issue discount securities or indexed securities, such portion of the principal amount as may be specified in the terms thereof) of all the debt securities of that series to be due and payable immediately by written notice thereof to us (and to the applicable trustee if given by the holders). However, at any time after such a declaration of acceleration with respect to debt securities of such series (or of all debt securities then outstanding under any indenture, as the case may be) has been made, but before a judgment or decree for payment of the money due has been obtained by the applicable trustee, the holders of not less than a majority in principal amount of outstanding debt securities of such series (or of all debt securities then outstanding under the applicable indenture, as the case may be) may rescind and annul such declaration and its consequences if:

Each indenture also will provide that the holders of not less than a majority in principal amount of the outstanding debt securities of any series (or of all debt securities then outstanding under the applicable indenture, as the case may be) may waive any past default with respect to the series and its consequences, except a:

15

Table of Contents

Each trustee will be required to give notice to the holders of debt securities within a certain number of days of a default under the applicable indenture unless the default has been cured or waived; provided, however, that the trustee may withhold notice to the holders of any series of debt securities of any default with respect to the series (except a default in the payment of the principal of (or premium, if any) or interest on any debt security of the series or in the payment of any sinking fund installment in respect of any debt security of the series) if specified responsible officers of the trustee consider withholding the notice to be in the interest of the holders.

Each indenture will prohibit the holders of debt securities of any series from instituting any proceedings, judicial or otherwise, with respect to the indenture or for any remedy thereunder, except in the case of failure of the applicable trustee, for a certain period of time after the trustee has received a written request to institute proceedings in respect of an event of default from the holders of not less than a majority in principal amount of the outstanding debt securities of such series, as well as the furnishing of indemnity reasonably satisfactory to it. This provision will not prevent any holder of debt securities from instituting a suit to enforce the payment of the principal of (and premium, if any) and interest on the debt securities at the respective due dates thereof.

Subject to the indenture, no trustee will be under any obligation to exercise any of its rights or powers under an indenture at the request or direction of any holders of any series of debt securities then outstanding, unless the holders furnish the trustee thereunder reasonable security or indemnity. The holders of not less than a majority in principal amount of the outstanding debt securities of any series (or of all debt securities then outstanding under an indenture, as the case may be) will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the applicable trustee, or of exercising any trust or power conferred upon the trustee. However, a trustee may refuse to follow any direction which is in conflict with any law or the applicable indenture, which may involve the trustee in personal liability or which may be unduly prejudicial to the holders of debt securities of such series not joining therein.

Within a certain period of time of the close of each fiscal year, we will be required to deliver to each trustee, a certificate, signed by one of several specified officers, stating whether or not the officer has knowledge of any default under the applicable indenture and, if so, specifying each default and the nature and status thereof.

Investors should review the accompanying prospectus supplement for information with respect to any deletions from, modifications of or additions to the events of default or covenants that are described herein, including any addition of a covenant or other provision providing event risk or similar protection.

Modification of the Indenture

The indenture will likely be modified or amended, with the consent of the holders of not less than a majority in principal amount of each series of the outstanding debt securities issued under the indenture affected by the modification or amendment, provided that no modification or amendment may, without the consent of each affected holder of the debt securities:

16

Table of Contents

A record date may be set for any act of the holders with respect to consenting to any amendment.

The holders of not less than a majority in principal amount of the outstanding debt securities of each series affected thereby will have the right to waive our compliance with certain covenants in the indenture. Each indenture will contain provisions for convening meetings of the holders of debt securities of a series to take permitted action. Under certain circumstances, we and the trustee may make modifications and amendments to an indenture without the consent of any holders of outstanding debt securities.

Redemption of Debt securities

The debt securities may be redeemed at any time at our option, in whole or in part, to protect our status as a REIT. The debt securities will also be subject to optional or mandatory redemption on terms and conditions described in the accompanying prospectus supplement.

Conversion of Debt securities

The terms and conditions, if any, upon which any debt securities are convertible into shares of our common stock or preferred stock will be set forth in the applicable prospectus supplement relating thereto. The terms will include:

Subordination

Upon any distribution to our creditors in a liquidation, dissolution or reorganization, the payment of the principal of and interest on any subordinated securities will be subordinated to the extent provided in the applicable indenture to the prior payment in full of all senior securities. No payment of principal or interest will be permitted to be made on subordinated securities at any time if any payment default or any other default which permits accelerations exists. After all senior securities are paid in full and until the subordinated securities are paid in full, holders of subordinated securities will be subrogated to the right of holders of senior securities to the extent that distributions otherwise payable to holders of subordinated securities have been applied to the payment of senior securities. By reason of any subordination, in the event of a distribution of assets upon our insolvency, some of our general creditors may recover more, ratably, than holders of subordinated securities. The accompanying prospectus supplement or the information incorporated herein by reference will contain the approximate amount of senior securities outstanding as of the end of our most recent fiscal quarter.

Global Debt Securities

The debt securities of a series may be issued in whole or in part in global form. The global securities will be deposited with a depositary, or with a nominee for a depositary, identified in the accompanying prospectus supplement. In this case, one or more global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal amount of outstanding debt securities of the series to be represented by the global security or securities. Unless and until it is exchanged in whole or in part for debt securities in definitive form, a global security may not be transferred except as a whole by the depositary for the global security to a nominee of the depositary or by a nominee of the depositary to the depositary or another nominee of the depositary or by the depositary or any nominee to a successor of the depositary or a nominee of the successor.

The specific material terms of the depositary arrangement with respect to any portion of a series of debt securities to be represented by a global security will be described in the accompanying prospectus supplement. We anticipate that the following provisions will apply to all depositary arrangements.

Upon the issuance of a global security, the depositary for the global security will credit, on its book-entry registration and transfer system, the respective principal amounts of the debt securities represented by the global security to the accounts of persons, or participants, that have accounts with the depositary. The accounts to be credited will be designated by any underwriters or agents participating in the distribution of the debt securities. Ownership of beneficial interests in a global security will be limited to participants or persons that may hold interests through participants. Ownership of beneficial interests in the global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by the depositary for the global security, with respect to interests of participants, or by participants or persons that hold through participants, with respect to interests of persons other than participants. So long as the depositary for a global security, or its nominee, is the registered owner of the global security, the depositary or the nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by the global security for all purposes under the indenture; provided, however, that for purposes of obtaining any consents or directions required to be given by the holders of the debt securities, we, the trustee and our agents will treat a person as the holder of the principal amount of debt securities as specified in a written statement of the depositary. Except as set forth herein or otherwise provided in the accompanying prospectus supplement, owners of beneficial interests in a global security will not be entitled to have the debt securities represented by the global security registered in their names, will not receive physical delivery of the debt securities in definitive form and will not be considered the owners or holders thereof under the indenture.

Principal, premium, if any, and interest payments on debt securities represented by a global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the global security. Neither we, the trustee nor any paying agent for the debt securities, will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the global security or for maintaining, supervising or reviewing any records relating to the beneficial ownership interests.

We expect that the depositary for any debt securities represented by a global security, upon receipt of any payment of principal, premium, if any, or interest will immediately credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the global security as shown on the records of the depositary. We also expect that payments by participants will be governed by standing instructions and customary practices, as is now the case with the securities held for the accounts of customers registered in “street names” and will be the responsibility of the participants.

If the depositary for any debt securities represented by a global security is at any time unwilling or unable to continue as depositary and a successor depositary is not appointed by us within the period of time set forth in the

18

Table of Contents

indenture, we will issue the debt securities in definitive form in exchange for the global security. In addition, we may at any time, and in our sole discretion, determine not to have any of the debt securities of a series represented by one or more global securities and, in that event, will issue debt securities of the series in definitive form in exchange for all of the global security or securities representing the debt securities.

The laws of some states require that certain purchasers of securities take physical delivery of the securities in definitive form. These laws may impair the ability to transfer beneficial interests in debt securities represented by global securities.

Governing Law

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

DESCRIPTION OF DEPOSITARY SHARES

General

We may issue depositary shares, each of which will represent a fractional interest of a share of a particular class or series of our preferred stock, as specified in the accompanying prospectus supplement which will more fully describe the terms of those depositary shares. Shares of a class or series of preferred stock represented by depositary shares will be deposited under a separate deposit agreement among us, the depositary named therein and the holders from time to time of the depositary receipts issued by the preferred stock depositary which will evidence the depositary shares. Subject to the terms of the deposit agreement, each owner of a depositary receipt will be entitled, in proportion to the fractional interest of a share of a particular class or series of preferred stock represented by the depositary shares evidenced by that depositary receipt, to all the rights and preferences of the class or series of preferred stock represented by those depositary shares (including dividend, voting, conversion, redemption and liquidation rights).

The depositary shares to be issued will be evidenced by depositary receipts issued pursuant to the applicable deposit agreement. Immediately following the issuance and delivery of a class or series of preferred stock by us to the preferred stock depositary, we will cause the preferred stock depositary to issue, on our behalf, the depositary receipts. The following description of the depositary shares, and any description of the depositary shares in an accompanying prospectus supplement, may not be complete and is subject to, and qualified in its entirety by reference to, the underlying deposit agreement and the depositary receipt, which we will file with the SEC at or prior to the time of the sale of the depositary shares. You should refer to, and read this summary together with, the deposit agreement and related depositary receipt. You can obtain copies of any form of deposit agreement or other agreement pursuant to which the depositary shares are issued by following the directions described under the caption “Where You Can Find More Information” in the accompanying prospectus supplement.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions received in respect of our preferred stock to the record holders of depositary shares relating to such preferred stock in proportion to the number of such depositary shares owned by such holders. The depositary shall distribute only such amount, however, as can be distributed without attributing to any holder of depositary shares a fraction of one cent, and the balance not so distributed shall be added to and treated as part of the next sum received by the depositary for distribution to record holders of depositary shares.

19

Table of Contents

In the event of a distribution other than in cash, the depositary will distribute property received by it to the record holders of depositary shares entitled thereto, unless the depositary determines that it is not feasible to make such distribution, in which case the depositary may, with our approval, sell such property and distribute the net proceeds from such sale to such holders.

The deposit agreement will also contain provisions relating to the manner in which any subscription or similar rights offered by us to holders of our preferred stock shall be made available to the holders of depositary shares.

Redemption of Depositary Shares

If a class or series of preferred stock represented by depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the depositary resulting from the redemption, in whole or in part, of such class or series of preferred stock held by the depositary. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share payable with respect to such class or series of preferred stock. Whenever we redeem shares of preferred stock held by the depositary, the depositary will redeem as of the same redemption date the number of depositary shares representing the shares of preferred stock so redeemed. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or pro rata as may be determined by the depositary.

After the date fixed for redemption, the depositary shares so called for redemption will no longer be outstanding and all rights of the holders of the depositary shares will cease, except the right to receive the money, securities or other property payable upon such redemption and any money, securities or other property to which the holders of such depositary shares were entitled upon such redemption upon surrender to the depositary of the depositary receipts evidencing such depositary shares.

Voting Our Preferred Stock

Upon receipt of notice of any meeting at which the holders of preferred stock are entitled to vote, the depositary will mail the information contained in such notice of meeting to the record holders of the depositary shares relating to such preferred stock. Each record holder of such depositary shares on the record date (which will be the same date as the record date for our preferred stock) will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of preferred stock represented by such holder’s depositary shares. The depositary will endeavor, insofar as practicable, to vote the amount of preferred stock represented by such depositary shares in accordance with such instructions, and we will agree to take all action which may be deemed necessary by the depositary in order to enable the depositary to do so. The depositary may abstain from voting shares of preferred stock to the extent it does not receive specific instructions from the holders of depositary shares representing such preferred stock.

Amendment and Termination of the Depositary Agreement

The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may at any time be amended by agreement between the depositary and us. However, any amendment that materially and adversely alters the rights of the holders of depositary shares will not be effective unless such amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The deposit agreement may be terminated by us or the depositary only if (i) all outstanding depositary shares have been redeemed or (ii) there has been a final distribution in respect of our preferred stock in connection with any liquidation, dissolution or winding up of the Company and such distribution has been distributed to the holders of depositary receipts.

20

Table of Contents

Charges of Depositary

We will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. We will pay charges of the depositary in connection with the initial deposit of our preferred stock and any redemption of our preferred stock. Holders of depositary receipts will pay other transfer and other taxes and governmental charges and such other charges, including a fee for the withdrawal of shares of preferred stock upon surrender of depositary receipts, as are expressly provided in the deposit agreement to be for their accounts.

Miscellaneous

The depositary will forward to holders of depositary receipts all reports and communications from the Company that are delivered to the depositary and that we are required to furnish to holders of preferred stock.

Neither the depositary nor the Company will be liable if it is prevented or delayed by law or any circumstance beyond its control in performing its obligations under the deposit agreement. The obligations of the depositary and the Company under the deposit agreement will be limited to performance in good faith of their duties thereunder and they will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless satisfactory indemnity is furnished. They may rely upon written advice of counsel or accountants, or upon information provided by persons presenting preferred stock for deposit, holders of depositary receipts or other persons believed to be competent and on documents believed to be genuine.

Resignation and Removal of the Depositary

The depositary may resign at any time by delivering to us notice of its election to do so, and we may at any time remove the depositary, any such resignation or removal to take effect upon the appointment of a successor depositary and its acceptance of such appointment. Such successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal.

Restrictions on Ownership

The deposit agreement will contain provisions restricting the ownership and transfer of depositary shares. Such restrictions will be described in the accompanying prospectus supplement and will be referenced on the applicable depositary receipts.

DESCRIPTION OF SUBSCRIPTION RIGHTS

We may issue subscription rights to purchase one or more series or classes of common stock, preferred stock, debt securities and depositary shares. We may issue subscription rights independently or together with any other offered security, which may or may not be transferable by the stockholder. In connection with any offering of subscription rights, we may enter into a standby arrangement with one or more underwriters or other purchasers pursuant to which the underwriters or other purchasers may be required to purchase any securities remaining unsubscribed for after such offering.

The accompanying prospectus supplement relating to any subscription rights we may offer will contain the specific terms of the subscription rights. These terms may include the following:

21

Table of Contents

The description in the accompanying prospectus supplement of any subscription rights we offer will not necessarily be complete and will be qualified in its entirety by reference to the applicable subscription rights certificate or subscription rights agreement, which will be filed with the SEC if we offer subscription rights. For more information on how you can obtain copies of any subscription rights certificate or subscription rights agreement if we offer subscription rights, see “Where You Can Find More Information.” We urge you to read the applicable subscription rights certificate, the applicable subscription rights agreement and any accompanying prospectus supplement in their entirety.

BOOK ENTRY PROCEDURES AND SETTLEMENT

We may issue the securities offered pursuant to this prospectus in certificated or book-entry form or in the form of one or more global securities. The accompanying prospectus supplement will describe the manner in which the securities offered thereby will be issued.

CERTAIN PROVISIONS OF MARYLAND LAW AND OF OUR CHARTER AND BYLAWS

Classification of our Board of Directors

Our board of directors is currently comprised of nine members. Our board is divided into three classes of directors. Directors of each class are elected for a three-year term and until their respective successor is duly elected and qualifies, and each year one class of directors will be elected by the stockholders. Any director elected to fill a vacancy shall serve for the remainder of the full term of the class in which the vacancy occurred and until a successor is elected and qualifies. We believe that classification of our board of directors helps to assure the continuity and stability of our business strategies and policies as determined by our directors. Holders of shares of our capital stock have no right to cumulative voting in the election of directors. Consequently, at each annual meeting of stockholders, the holders of a majority of the capital stock entitled to vote are able to elect all of the successors of the class of directors whose terms expire at that meeting.

Our classified board could have the effect of making the replacement of incumbent directors more time consuming and difficult. At least two annual meetings of stockholders, instead of one, will generally be required to effect a change in a majority of our board of directors. Thus, our classified board could increase the likelihood that incumbent directors will retain their positions. The staggered terms of directors may delay, defer or prevent a tender offer or an attempt to change control of us or another transaction that might involve a premium price for our common stock that might be in the best interest of our stockholders.

22

Table of Contents

Removal of Directors

Any director may be removed only for cause by the stockholders upon the affirmative vote of at least two-thirds of all the votes entitled to be cast generally in the election of directors.

Restrictions on Ownership and Transfer

In order for us to qualify as a REIT, not more than 50% (by value) of our outstanding shares may be owned by any five or fewer individuals (including some tax-exempt entities) during the last half of each taxable year, and the outstanding shares must be owned by 100 or more persons independent of us and each other during at least 335 days of a 12-month taxable year or during a proportionate part of a shorter taxable year for which an election to be treated as a REIT is made. We may prohibit certain acquisitions and transfers of shares to maintain our qualification as a REIT under the Code. However, no assurance can be given that this prohibition will be effective.

In order to assist our board of directors in preserving our status as a REIT, among other purposes, our charter contains an ownership limit which prohibits any person or group of persons from acquiring, directly or indirectly, beneficial or constructive ownership of more than 9.8% of our outstanding shares of capital stock (which includes our common stock and preferred stock). Shares owned by a person or a group of persons in excess of the ownership limit are deemed “excess shares.” Shares owned by a person who individually owns of record less than 9.8% of outstanding shares may nevertheless be excess shares if the person is deemed part of a group for purposes of this restriction.

Our charter stipulates that any purported issuance or transfer of shares shall be valid only with respect to those shares that do not result in the transferee-stockholder owning shares in excess of the ownership limit or in our disqualification as a REIT under the Code. If the transferee-stockholder acquires excess shares, the person is considered to have acted as our agent and holds the excess shares on behalf of the ultimate stockholder.

The ownership limit does not apply to offerors which, in accordance with applicable federal and state securities laws, make a cash tender offer, where at least 90% of the outstanding shares of our stock (not including shares or subsequently issued securities convertible into common stock which are held by the tender offeror and any “affiliates” or “associates” thereof within the meaning of the Exchange Act) are duly tendered and accepted pursuant to the cash tender offer. The ownership limit also does not apply to the underwriter in a public offering of our shares. The ownership limit also does not apply to a person or persons which our directors exempt from the ownership limit upon appropriate assurances that our qualification as a REIT is not jeopardized.

We have the authority to redeem excess shares immediately upon becoming aware of the existence of excess shares or after giving the holder of the excess shares 30 days to transfer the excess shares to any person or group of persons whose ownership of such shares would not exceed the ownership limit, and therefore such shares would no longer be considered excess shares. The price paid upon redemption by us shall be the lesser of the price paid for such excess shares by the stockholder holding the excess shares or the fair market value of the excess shares.

Distributions

Distributions will be paid to investors who are stockholders as of the close of business on the applicable record date selected by our board of directors. We are required to make distributions to our stockholders sufficient to satisfy the REIT requirements. Generally, income distributed to our stockholders will not be taxable to us under federal income tax laws unless we fail to comply with the REIT requirements.

Unless otherwise specified in the governing instrument of the capital stock, distributions will be paid at the discretion of our board of directors based upon our earnings, cash flow, general financial condition and applicable law. Because we may receive income from interest or rents at various times during our fiscal year,

23

Table of Contents

distributions may not reflect our income earned in that particular distribution period but may be made in anticipation of cash flow, which we expect to receive during a later period of the year and may be made in advance of actual receipt in an attempt to make distributions relatively uniform. We may borrow to make distributions if the borrowing is necessary to maintain our REIT status, or if the borrowing is part of a liquidation strategy whereby the borrowing is done in anticipation of the sale of properties and the proceeds will be used to repay the loan.

Information Rights

Any stockholder, or his or her agent, upon written request, may, during usual business hours and for any lawful and proper purpose, inspect and copy our bylaws, minutes of the proceedings of our stockholders, our annual financial statements and any voting trust agreement that is on file at our principal office. In addition, one or more stockholders who together are, and for at least six months have been, record holders of 5% of any class of our stock are entitled to inspect and copy our stockholder and books of account list upon written request. The list will include the name and address of, and the number of shares owned by, each stockholder and will be available at our principal office within 20 days of the stockholder’s request. A 5% stockholder may also request in writing a statement of our affairs.

The rights of stockholders described herein are in addition to, and do not adversely affect rights provided to investors under, Rule 14a-7 promulgated under the Exchange Act, which provides that, upon request of investors and the payment of the expenses of the distribution, we are required to distribute specific materials to stockholders in the context of the solicitation of proxies for voting on matters presented to stockholders, or, at our option, provide requesting stockholders with a copy of the list of stockholders so that the requesting stockholders may make the distribution themselves.

Business Combinations

The MGCL prohibits “business combinations” between a corporation and an interested stockholder or an affiliate of an interested stockholder for five years after the most recent date on which the interested stockholder becomes an interested stockholder. These business combinations include a merger, consolidation, statutory share exchange, or, in circumstances specified in the statute, certain transfers of assets, certain stock issuances and transfers, liquidation plans and reclassifications involving interested stockholders and their affiliates. The MGCL defines an interested stockholder as:

A person is not an interested stockholder if the board of directors approves in advance the transaction by which the person otherwise would have become an interested stockholder. However, in approving the transaction, the board of directors may provide that its approval is subject to compliance, at or after the time of approval, with any terms and conditions determined by the board of directors.

After the five-year prohibition, any business combination between a corporation and an interested stockholder generally must be recommended by the board of directors and approved by the affirmative vote of at least:

24

Table of Contents

These super-majority vote requirements do not apply if the common stockholders receive a minimum price, as defined under Maryland law, for their shares in the form of cash or other consideration in the same form as previously paid by the interested stockholder for its shares.

The statute permits various exemptions from its provisions, including business combinations that are approved by the board of directors before the time that the interested stockholder becomes an interested stockholder.

Our board of directors has by resolution exempted any business combination between the corporation and our officers and directors from these provisions of the MGCL and, consequently, the five-year prohibition and the super-majority vote requirements will not apply to business combinations between us and any of our officers and directors unless our board later resolves otherwise.

Subtitle 8

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

We have elected to be subject to each of the above provisions of Title 3, Subtitle 8 of the MGCL.

Amendments to Our Charter and Bylaws

Our charter generally may be amended only if the amendment is declared advisable by our board of directors and approved by the affirmative vote of stockholders entitled to cast a majority of all of the votes entitled to be cast on the matter. Our board of directors, with the approval of a majority of the entire board, and without any action by our stockholders, may also amend our charter from time to time to increase or decrease the aggregate number of shares of stock or the number of shares of stock of any class or series we are authorized to issue.

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

Extraordinary Transactions

Under the MGCL, a Maryland corporation generally cannot dissolve, merge, sell all or substantially all of its assets, engage in a statutory share exchange or engage in similar transactions outside the ordinary course of business unless approved by the affirmative vote of stockholders entitled to cast at least two-thirds of the votes entitled to be cast on the matter unless a lesser percentage (but not less than a majority of all of the votes entitled to be cast on the matter) is set forth in the corporation’s charter. As permitted by the MGCL, our charter provides that any of these actions may be approved by the affirmative vote of stockholders entitled to cast a majority of all of the votes entitled to be cast on the matter.

25

Table of Contents

Operations

We generally are prohibited from engaging in certain activities, including acquiring or holding property or engaging in any activity that would cause us to fail to qualify as a REIT.

Term and Termination

Our charter provides for us to have a perpetual existence. Pursuant to our charter, and subject to the provisions of any of our classes or series of stock then outstanding and the approval by a majority of the entire board of directors, our stockholders by the affirmative vote of a majority of all of the votes entitled to be cast on the matter, may approve a plan of liquidation and dissolution.

Advance Notice of Director Nominations and New Business

Our bylaws provide that, with respect to an annual meeting of stockholders, nominations of persons for election to our board of directors and the proposal of business to be considered by stockholders at the annual meeting may be made only:

With respect to special meetings of stockholders, only the business specified in our notice of meeting may be brought before the meeting of stockholders and nominations of persons for election to our board of directors at which directors are to be elected pursuant to our notice of the meeting may be made only:

Power to Issue Additional Shares

We currently do not intend to issue any securities other than the shares described in this prospectus, although we may do so at any time, including upon the redemption of limited partnership interests that we may issue in connection with acquisitions of real property. We believe that the power to issue additional shares of stock and to classify or reclassify unissued shares of common stock or preferred stock and thereafter to issue the classified or reclassified shares provides us with increased flexibility in structuring possible future financings and acquisitions and in meeting other needs which might arise. These actions can be taken without stockholder approval, unless stockholder approval is required by applicable law or the rules of any stock exchange or automated quotation system on which our securities may be listed or traded. Although we have no present intention of doing so, we could issue a class or series of shares that could delay, defer or prevent a transaction or a change in control that might involve a premium price for holders of common stock or otherwise be in their best interest.

Control Share Acquisitions

The MGCL provides that a holder of “control shares” of a Maryland corporation acquired in a “control share acquisition” has no voting rights with respect to such shares except to the extent approved at a special meeting by

26

Table of Contents

the affirmative vote of two-thirds of the votes entitled to be cast on the matter, excluding shares of stock in a corporation in respect of which any of the following persons is entitled to exercise or direct the exercise of the voting power of shares of stock of the corporation in the election of directors: (i) a person who makes or proposes to make a control share acquisition, (ii) an officer of the corporation or (iii) an employee of the corporation who is also a director of the corporation. “Control shares” are voting shares of stock which, if aggregated with all other such shares of stock previously acquired by the acquiror or in respect of which the acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of voting power: (i) one-tenth or more but less than one-third, (ii) one-third or more but less than a majority, or (iii) a majority or more of all voting power. Control shares do not include shares that the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval. A “control share acquisition” means the acquisition of issued and outstanding control shares, subject to certain exceptions.

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

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

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

We have not opted out of the control share acquisition statute.

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

The business combination provisions and the control share acquisition provisions of the MGCL; the classification of our board of directors; the restrictions on the transfer and ownership of stock and the advance notice provisions of our bylaws could have the effect of delaying, deferring or preventing a transaction or a change in control that might involve a premium price for holders of common stock or otherwise be in their best interests.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

This section summarizes the current material federal income tax consequences generally resulting from our election to be taxed as a REIT and the current material federal income tax considerations relating to the ownership and disposition of our common stock, senior common stock and preferred stock. As used in this section, the terms “we” and “our” refer solely to Gladstone Commercial Corporation and not to our subsidiaries and affiliates which have not elected to be taxed as REITs for federal income tax purposes.

Table of Contents

This discussion is not exhaustive of all possible tax considerations and does not provide a detailed discussion of any state, local or foreign tax considerations. This discussion does not address all aspects of taxation that may be relevant to particular investors in light of their personal investment or tax circumstances, or to certain types of investors that are subject to special treatment under the federal income tax laws, such as insurance companies, tax-exempt organizations (except to the limited extent discussed below under “— Taxation of Tax-Exempt Stockholders”), financial institutions or broker-dealers, non-U.S. individuals and foreign corporations (except to the limited extent discussed below under “— Taxation of Non-U.S. Stockholders”) and other persons subject to special tax rules. Moreover, this summary assumes that our stockholders hold our stock as a capital asset for federal income tax purposes, which generally means property held for investment. The statements in this section are based on the current federal income tax laws, including the Code, the regulations promulgated by the U.S. Treasury Department, or the Treasury Regulations, rulings and other administrative interpretations and practices of the IRS, and judicial decisions, all as currently in effect, and all of which are subject to differing interpretations or to change, possibly with retroactive effect. This discussion is for general purposes only and is not tax advice. We cannot assure you that new laws, interpretations of law, or court decisions, any of which may take effect retroactively, will not cause any statement in this section to be inaccurate.

As discussed below in “— Taxation in Connection with Holding Securities other than our Stock,” we intend to describe in any prospectus supplement related to the offering of our debt securities, depositary shares or subscription rights, the material federal income tax considerations relating to the ownership and disposition of such securities as will be sold by us pursuant to that prospectus supplement.

We urge you to consult your own tax advisor regarding the specific tax consequences to you of acquisition, ownership and disposition of our securities and of our election to be taxed as a REIT. Specifically, you should consult your own tax advisor regarding the federal, state, local, foreign, and other tax consequences of such acquisition, ownership, disposition and election, and regarding potential changes in applicable tax laws.

Taxation of Our Company

We elected to be taxed as a REIT under the federal income tax laws beginning with our taxable year ended December 31, 2003. We believe that, beginning with such taxable year, we have been organized and have operated in such a manner as to qualify for taxation as a REIT under the Code, and we intend to continue to operate in such a manner. However, no assurances can be given that our beliefs or expectations will be fulfilled, since qualification as a REIT depends on our continuing to satisfy numerous asset, income, stock ownership and distribution tests described below, the satisfaction of which depends, in part, on our operating results.

The sections of the Code relating to qualification, operation and taxation as a REIT are highly technical and complex. The following discussion sets forth only the material aspects of those sections. This summary is qualified in its entirety by the applicable Code provisions and the related Treasury Regulations and administrative and judicial interpretations thereof.

In connection with the filing of this registration statement, Bass, Berry & Sims PLC has rendered an opinion that we have been organized and have operated in conformity with the requirements for qualification and taxation as a REIT pursuant to Sections 856 through 860 of the Code for our taxable years ended December 31, 2010 through December 31, 2012, and our organization and current and proposed method of operation will enable us to continue to qualify as a REIT for our taxable year ending December 31, 2013 and thereafter. Investors should be aware that Bass, Berry & Sims PLC’s opinion is based on the federal income tax laws governing qualification as a REIT as of the date of such opinion, which is subject to change, possibly on a retroactive basis, is not binding on the IRS or any court, and speaks only as of the date issued. In addition, Bass, Berry & Sims PLC’s opinion is based on customary assumptions and is conditioned upon certain representations made by us as to factual matters, including representations regarding the nature of our assets and the future conduct of our

28

Table of Contents

business. Moreover, our continued qualification and taxation as a REIT depend on our ability to meet, on a continuing basis, through actual results, certain qualification tests set forth in the federal income tax laws. Those qualification tests involve the percentage of our gross income that we earn from specified sources, the percentage of our assets that falls within specified categories, the diversity of our stock ownership, and the percentage of our earnings that we distribute. Bass, Berry & Sims PLC will not review our compliance with those tests on a continuing basis. Accordingly, no assurance can be given that the actual results of our operations for any particular taxable year will satisfy such requirements. Bass, Berry & Sims PLC’s opinion does not foreclose the possibility that we may have to use one or more of the REIT savings provisions described below, which may require us to pay a material excise or penalty tax in order to maintain our REIT qualification. For a discussion of the tax consequences of our failure to maintain our qualification as a REIT, see “— Failure to Qualify as a REIT” below.

If we maintain our qualification as a REIT, we generally will not be subject to federal income tax on the taxable income that we distribute to our stockholders because we will be entitled to a deduction for dividends that we pay. The benefit of that tax treatment is that it avoids the “double taxation,” or taxation at both the corporate and stockholder levels, that generally results from owning stock in a corporation. In general, income generated by a REIT is taxed only at the stockholder level if such income is distributed by the REIT to its stockholders. We will be subject to federal tax, however, in the following circumstances:

29

Table of Contents

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

Requirements for Qualification as a REIT

A REIT is a corporation, trust or association that satisfies each of the following requirements:

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

(2) Its beneficial ownership is evidenced by transferable shares of stock, or by transferable shares or certificates of beneficial interest;

(3) It would be taxable as a domestic corporation, but for Sections 856 through 860 of the Code, i.e. the REIT provisions;

(4) It is neither a financial institution nor an insurance company subject to special provisions of the federal income tax laws;

(5) At least 100 persons are beneficial owners of its stock or ownership shares or certificates (determined without reference to any rules of attribution);

(6) Not more than 50% in value of its outstanding stock or shares of beneficial interest are owned, directly or indirectly, by five or fewer individuals, which the federal income tax laws define to include certain entities, during the last half of any taxable year;

(7) It elects to be a REIT, or has made such election for a previous taxable year, and satisfies all relevant filing and other administrative requirements established by the IRS that must be met to qualify to be taxed as a REIT for federal income tax purposes;

30

Table of Contents

(8) It uses a calendar year for federal income tax purposes and complies with the recordkeeping requirements of the federal income tax laws; and

(9) It meets certain other qualifications, tests described below, regarding the sources of its gross income, the nature and diversification of its assets and the distribution of its income.

We must satisfy requirements 1 through 4, and 8 during our entire taxable year and must satisfy requirement 5 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. If we comply with certain requirements for ascertaining the beneficial ownership of our outstanding stock in a taxable year and have no reason to know that we violated requirement 6, we will be deemed to have satisfied requirement 6 for that taxable year. For purposes of determining stock ownership under requirement 6, an “individual” generally includes a supplemental unemployment compensation benefits plan, a private foundation, or a portion of a trust permanently set aside or used exclusively for charitable purposes. An “individual,” however, generally does not include a trust that is a qualified employee pension or profit sharing trust under the federal income tax laws, and beneficiaries of such a trust will be treated as holding our stock in proportion to their actuarial interests in the trust for purposes of requirement 6.

Our charter provides for restrictions regarding the ownership and transfer of our stock that should allow us to continue to satisfy these requirements. The provisions of the charter restricting the ownership and transfer of our stock are described in “Certain Provisions of Maryland Law And of Our Charter And Bylaws — Restrictions on Ownership and Transfer.” We believe we have issued sufficient stock with enough diversity of ownership to satisfy requirements 5 and 6 set forth above. For purposes of requirement 8, we have adopted December 31 as our year end for federal income tax purposes, and thereby satisfy this requirement.

Qualified REIT Subsidiaries. A “qualified REIT subsidiary” generally is a corporation, all of the stock of which is owned, directly or indirectly, by a REIT and that is not treated as a taxable REIT subsidiary. A corporation that is a “qualified REIT subsidiary” is treated as a division of the REIT that owns, directly or indirectly, all of its stock and not as a separate entity for federal income tax purposes. Thus, all assets, liabilities, and items of income, deduction, and credit of a “qualified REIT subsidiary” are treated as assets, liabilities, and items of income, deduction, and credit of the REIT that directly or indirectly owns the qualified REIT subsidiary. Consequently, in applying the REIT requirements described herein, the separate existence of any “qualified REIT subsidiary” that we own will be ignored, and all assets, liabilities, and items of income, deduction, and credit of such subsidiary will be treated as our assets, liabilities, and items of income, deduction, and credit.

Other Disregarded Entities and Partnerships. An unincorporated domestic entity, such as a partnership or limited liability company, that has a single owner, as determined under the federal income tax laws, generally is not treated as an entity separate from its owner for federal income tax purposes. We own various direct and indirect interests in entities that are classified as partnerships, limited liability companies and trusts for state law purposes. Nevertheless, these entities currently are not treated as entities separate from us for federal income tax purposes because we currently own, directly or indirectly, all of the ownership interests in these entities. Consequently, the assets and items of gross income of these entities will be treated as our assets and items of gross income for purposes of applying the various REIT qualification tests.

An unincorporated domestic entity with two or more owners, as determined under the federal income tax laws, generally is taxed as a partnership for federal income tax purposes. In the case of a REIT that is a partner in a partnership, the REIT is treated as owning its proportionate share of the assets of the partnership and as earning its allocable share of the gross income of the partnership for purposes of the applicable REIT qualification tests. Thus, our proportionate share of the assets and items of gross income of any partnership, joint venture, or limited liability company that is taxed as a partnership for federal income tax purposes would be treated as our assets and items of gross income for purposes of applying the various REIT qualification tests. For purposes of the 10% value test (described in “— Asset Tests”), our proportionate share would be based on our proportionate interest in the equity interests and certain debt securities issued by a partnership. For all of the other asset and income tests, our proportionate share would be based on our proportionate interest in the capital of the partnership.

Taxable REIT Subsidiaries. A REIT is permitted to own, directly or indirectly, up to 100% of the stock of one or more “taxable REIT subsidiaries.” The subsidiary and the REIT generally must jointly elect to treat the subsidiary as a taxable REIT subsidiary. A corporation of which a taxable REIT subsidiary directly or indirectly owns more than 35% of the voting power or value of the securities, however, is automatically treated as a taxable REIT subsidiary without an election. The separate existence of a taxable REIT subsidiary is not ignored for federal income tax purposes. A taxable REIT subsidiary is a fully taxable corporation that may earn income that would not be qualifying income for purposes of the gross income tests, as described below, if earned directly by the parent REIT. Accordingly, a taxable REIT subsidiary generally is subject to corporate income tax on its earnings, which may reduce the cash flow generated by us and our subsidiaries in the aggregate, and may reduce our ability to make distributions to our stockholders.

We are not treated as holding the assets of a taxable REIT subsidiary or as receiving any income that the taxable REIT subsidiary earns. Rather, the stock issued by a taxable REIT subsidiary to us is an asset in our hands, and we treat the distributions paid to us from such taxable REIT subsidiary, if any, as income. This treatment may affect our compliance with the gross income tests and asset tests. Because a REIT does not include the assets and income of taxable REIT subsidiaries in determining the REIT’s compliance with REIT requirements, such entities may be used by the REIT to indirectly undertake activities that the REIT requirements might otherwise preclude the REIT from doing directly or through a pass-through subsidiary (e.g., a partnership). If dividends are paid to us by one or more of our domestic taxable REIT subsidiaries that we may own, then a portion of such dividends that we distribute to our stockholders who are taxed at individual rates generally will be eligible for taxation at the preferential income tax rates applicable to qualified dividend income rather than at ordinary income rates. See “— Annual Distribution Requirements” and “—Taxation of Taxable U.S. Stockholders — Distributions.”

A taxable REIT subsidiary pays federal income tax at corporate rates on any income that it earns. Restrictions imposed on REITs and their taxable REIT subsidiaries are intended to ensure that taxable REIT subsidiaries will be subject to appropriate levels of federal income taxation. These restrictions limit the deductibility of interest paid or accrued by a taxable REIT subsidiary to its parent REIT and impose a 100% excise tax on transactions between a taxable REIT subsidiary and its parent REIT or the REIT’s tenants that are not conducted on an arm’s-length basis. We may engage in activities indirectly through a taxable REIT subsidiary as necessary or convenient to obtain the benefit of income or services that would jeopardize our REIT status if we engaged in the activities directly. In particular, we likely would engage in activities through a taxable REIT subsidiary if we wished to provide services to unrelated parties which might produce income that does not qualify under the gross income tests described below. We also might dispose of an unwanted asset through a taxable REIT subsidiary as necessary or convenient to avoid the 100% tax on income from prohibited transactions. See “— Gross Income Tests — Rents from Real Property” and “— Gross Income Tests — Prohibited Transactions.”

Gross Income Tests

We must satisfy two gross income tests annually to maintain our qualification as a REIT. First, at least 75% of our gross income for each taxable year must consist of defined types of income that we derive, directly or indirectly, from investments relating to real property or mortgages on real property or qualified temporary investment income. Qualifying income for purposes of that 75% gross income test generally includes:

32

Table of Contents

Second, in general, at least 95% of our gross income for each taxable year must consist of income that is qualifying income for purposes of the 75% gross income test, other types of interest and dividends, gain from the sale or disposition of stock or securities, or any combination of these.

Cancellation of indebtedness income and gross income from a sale of property that we hold primarily for sale to customers in the ordinary course of business will be excluded from gross income for purposes of the 75% and 95% gross income tests. In addition, any gains from “hedging transactions,” as defined in “— Hedging Transactions,” that are clearly and timely identified as such will be excluded from gross income for purposes of the 75% and 95% gross income tests. Finally, certain foreign currency gains will be excluded from gross income for purposes of one or both of the gross income tests.

The following paragraphs discuss the specific application of the gross income tests to us.

Rents from Real Property. Rent that we receive for the use of our real property will qualify as “rents from real property,” which is qualifying income for purposes of the 75% and 95% gross income tests, only if the following conditions are met:

First, the rent must not be based in whole or in part on the income or profits of any person. Participating rent, however, will qualify as “rents from real property” if it is based on percentages of receipts or sales and the percentages:

More generally, the rent will not qualify as “rents from real property” if, considering the relevant lease and all the surrounding circumstances, the arrangement does not conform with normal business practice, but is in reality used as a means of basing the rent on income or profits. We intend to set and accept rents which are fixed dollar amounts or a fixed percentage of gross revenue and not to any extent determined by reference to any person’s income or profits, in compliance with the rules above.

Second, we generally must not own, actually or constructively, 10% or more of the stock or the assets or net profits of any tenant, referred to as a “related-party tenant,” other than a taxable REIT subsidiary. The constructive ownership rules generally provide that, if 10% or more in value of our stock is owned, directly or indirectly, by or for any person, we are considered as owning the stock owned, directly or indirectly, by or for such person. Because the constructive ownership rules are broad and it is not possible to monitor direct and indirect transfers of our stock continually, no absolute assurance can be given that such transfers or other events of which we have no knowledge will not cause us to own constructively 10% or more of a tenant (or a subtenant, in which case only rent attributable to the subtenant is disqualified), other than a taxable REIT subsidiary.

Under an exception to the related-party tenant rule described in the preceding paragraph, rent that we receive from a taxable REIT subsidiary will qualify as “rents from real property” as long as (1) at least 90% of the leased space in the property is leased to persons other than taxable REIT subsidiaries and related-party tenants, and (2) the amount paid by the taxable REIT subsidiary to rent space at the property is substantially comparable to rents paid by other tenants of the property for comparable space. The “substantially comparable” requirement must be satisfied when the lease is entered into, when it is extended, and when the lease is modified,

33

Table of Contents

if the modification increases the rent paid by the taxable REIT subsidiary. If the requirement that at least 90% of the leased space in the related property is rented to unrelated tenants is met when a lease is entered into, extended, or modified, such requirement will continue to be met as long as there is no increase in the space leased to any taxable REIT subsidiary or related-party tenant. Any increased rent attributable to a modification of a lease with a taxable REIT subsidiary in which we own, directly or indirectly, more than 50% of the voting power or value of the stock (a “controlled taxable REIT subsidiary”) will not be treated as “rents from real property.”

Third, we must not furnish or render noncustomary services, other than a de minimis amount of noncustomary services, as described below, to the tenants of our properties, or manage or operate our properties, other than through an independent contractor from whom we do not derive or receive any income or a taxable REIT subsidiary. We generally may provide services directly to our tenants, however, if such services are “usually or customarily rendered” in connection with the rental of space for occupancy only and are not considered to be provided for the tenants’ convenience. In addition, we may provide a minimal amount of “noncustomary” services to the tenants of a property, other than through an independent contractor from whom we do not derive or receive any income or a taxable REIT subsidiary, as long as the income attributable to the services (valued at not less than 150% of the direct cost of performing such services) does not exceed 1% of the income from the related property. We have not performed, and do not intend to perform, any services other than customary ones for our tenants, unless such services are provided through independent contractors from whom we do not derive or receive any income or taxable REIT subsidiaries.

If the rent from a lease of property does not qualify as “rents from real property” because (1) the rent is based on the net income or profits of the tenant, (2) the lessee is a related-party tenant or fails to qualify for the exception to the related-party tenant rule for qualifying taxable REIT subsidiaries, or (3) we furnish noncustomary services to the tenants of the property, or manage or operate the property, other than through a qualifying independent contractor or a taxable REIT subsidiary, that are in excess of 1% of our gross income from the related property, none of the rent from the property would qualify as “rents from real property.” In any of these circumstances, we could lose our REIT status, unless we qualified for certain statutory relief provisions, because we might be unable to satisfy either the 75% or 95% gross income test.

Tenants may be required to pay, in addition to base rent, reimbursements for certain amounts we are obligated to pay to third parties (such as a lessee’s proportionate share of a property’s operational or capital expenses), penalties for nonpayment or late payment of rent or additions to rent. These and other similar payments should qualify as “rents from real property.” To the extent they do not, they should be treated as interest that qualifies for the 95% gross income test.

In addition, rent attributable to any personal property leased in connection with a lease of real property will not qualify as “rents from real property” if the rent attributable to such personal property exceeds 15% of the total rent received under the lease. The rent attributable to personal property under a lease is the amount that bears the same ratio to total rent under the lease for the taxable year as the average of the fair market values of the leased personal property at the beginning and at the end of the taxable year bears to the average of the aggregate fair market values of both the real and personal property covered by the lease at the beginning and at the end of such taxable year, or the personal property ratio. If a portion of the rent that we receive from a property does not qualify as “rents from real property” because the rent attributable to personal property exceeds 15% of the total rent for a taxable year, the portion of the rent that is attributable to personal property will not be qualifying income for purposes of either the 75% or 95% gross income test. Thus, if such rent attributable to personal property, plus any other income that is nonqualifying income for purposes of the 95% gross income test, during a taxable year exceeds 5% of our gross income during the year, we would lose our REIT status, unless we qualified for certain statutory relief provisions. We believe that any income attributable to personal property will not jeopardize our ability to maintain our qualification as a REIT. There can be no assurance, however, that the IRS would not challenge our calculation of a personal property ratio, or that a court would agree with our

34

Table of Contents

calculation. If such a challenge were successful, we could fail to satisfy the 75% or 95% gross income test and thus potentially lose our REIT status.

Interest. For purposes of the 75% and 95% gross income tests, the term “interest” generally does not include any amount received or accrued, directly or indirectly, if the determination of such amount depends 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 the term “interest” solely because it is based on a fixed percentage or percentages of receipts or sales. Furthermore, to the extent that interest from a loan that is based on the profit or net cash proceeds from the sale of the property securing the loan constitutes a “shared appreciation provision,” income attributable to such participation feature will be treated as gain from the sale of the secured property.

We may invest opportunistically from time to time in mortgage debt and mezzanine loans. Interest on debt secured by a mortgage on real property or on interests in real property, including, for this purpose, discount points, prepayment penalties, loan assumption fees, and late payment charges that are not compensation for services, generally is qualifying income for purposes of the 75% gross income test. In general, if a loan is secured by real property and other property and the highest principal amount of the loan outstanding during a taxable year exceeds the fair market value of the real property securing the loan, determined as of (i) the date we agreed to acquire or originate the loan or (ii) in the event of a “significant modification,” the date we modified the loan, then a portion of the interest income from such loan will not be qualifying income for purposes of the 75% gross income test, but will be qualifying income for purposes of the 95% gross income test. The portion of the interest income that will not be qualifying income for purposes of the 75% gross income test will be equal to the interest income attributable to the portion of the principal amount of the loan that is not secured by real property. The principal amount of the loan that is not secured by real property is the amount by which the loan exceeds the value of the real estate that is security for the loan.

Mezzanine loans are loans secured by equity interests in an entity that directly or indirectly owns real property, rather than by a direct mortgage of the real property. IRS Revenue Procedure 2003-65 provides a safe harbor pursuant to which a mezzanine loan, if it meets each of the requirements contained in the Revenue Procedure, will be treated by the IRS as a real estate asset for purposes of the REIT asset tests described below, and interest derived from it will be treated as qualifying mortgage interest for purposes of the 75% gross income test. Although the Revenue Procedure provides a safe harbor on which taxpayers may rely, it does not prescribe rules of substantive tax law. We anticipate that any mezzanine loans that we originate or acquire typically will not meet all of the requirements for reliance on this safe harbor. Nevertheless, we intend to invest in any mezzanine loans in a manner that will enable us to continue to satisfy the gross income tests and asset tests.

Dividends. Our share of any dividends received from any corporation (including any taxable REIT subsidiary, but excluding any REIT or qualified REIT subsidiary) in which we own an equity interest will qualify for purposes of the 95% gross income test but not for purposes of the 75% gross income test. Our share of any dividends received from any other REIT in which we own an equity interest will be qualifying income for purposes of the 75% and 95% gross income tests. Any dividends received by us from a qualified REIT subsidiary will be excluded from gross income for purposes of the 75% and 95% gross income tests.

Prohibited Transactions. A REIT will incur a 100% tax on the net income derived from any sale or other disposition of property, other than foreclosure property, that the REIT holds primarily for sale to customers in the ordinary course of a trade or business, and net income derived from such prohibited transactions is excluded from gross income solely for purposes of the 75% and 95% gross income tests. Whether a REIT holds an asset “primarily for sale to customers in the ordinary course of a trade or business” depends, however, on the facts and circumstances that exist from time to time, including those related to a particular asset. A safe harbor to the characterization of the sale of property by a REIT as a prohibited transaction and the resulting imposition of the 100% prohibited transactions tax is available, however, if the following requirements are met:

35

Table of Contents

We will attempt to comply with the terms of the safe-harbor provisions in the federal income tax laws prescribing when an asset sale will not be characterized as a prohibited transaction. We cannot assure you, however, that we will be able to comply with the safe-harbor provisions or that we will avoid owning property that may be characterized as property held “primarily for sale to customers in the ordinary course of a trade or business.” We may hold and dispose of certain properties through a taxable REIT subsidiary if we conclude that the sale or other disposition of such property may not fall within the safe-harbor provisions. The 100% prohibited transaction tax will not apply to gains from the sale of property that is held through a taxable REIT subsidiary or other taxable corporation, although such income will be taxed to the taxable REIT subsidiary or other taxable corporation at federal corporate income tax rates.

Foreclosure Property. We will be subject to tax at the maximum corporate rate on any income from foreclosure property, which includes certain foreign currency gains and related deductions, other than income that otherwise would be qualifying income for purposes of the 75% gross income test, less expenses directly connected with the production of that income. Gross income from foreclosure property, however, will qualify under the 75% and 95% gross income tests. “Foreclosure property” is any real property, including interests in real property, and any personal property incident to such real property:

A REIT will not be considered to have foreclosed on a property, however, where the REIT takes control of the property as a mortgagee-in-possession and cannot receive any profit or sustain any loss except as a creditor of the mortgagor. Property generally ceases to be foreclosure property at the end of the third taxable year following the taxable year in which the REIT acquired the property (or longer if an extension is granted by the Secretary of the U.S. Treasury). This period (as extended, if applicable) terminates, and foreclosure property ceases to be foreclosure property on the first day:

Hedging Transactions. From time to time, we or our subsidiaries may enter into hedging transactions with respect to one or more of our or our subsidiaries’ assets or liabilities. Our or our subsidiaries’ hedging activities may include entering into interest rate swaps, caps, and floors, options to purchase such items, and futures and forward contracts. Income and gain from “hedging transactions” will be excluded from gross income for purposes of both the 75% and 95% gross income tests. A “hedging transaction” means either (1) any transaction entered into in the normal course of our or our subsidiaries’ trade or business primarily to manage the risk of interest rate, price changes, or currency fluctuations with respect to borrowings made or to be made, or ordinary obligations incurred or to be incurred, to acquire or carry real estate assets or (2) any transaction entered into primarily to manage the risk of currency fluctuations with respect to any item of income or gain that would be qualifying income under the 75% or 95% gross income test (or any property which generates such income or gain). We are required to clearly identify any such hedging transaction before the close of the day on which it was acquired, originated, or entered into and to satisfy other identification requirements. We intend to structure any hedging transactions in a manner that does not jeopardize our qualification as a REIT; however, no assurance can be given that our hedging activities will give rise to income that qualifies for purposes of either or both of the gross income tests.

Failure to Satisfy Gross Income Tests. We intend to monitor our sources of income, including any non-qualifying income received by us, and manage our assets so as to ensure our compliance with the gross income tests. If we fail to satisfy one or both of the gross income tests for any taxable year, we nevertheless may maintain our qualification as a REIT for that year if we qualify for relief under certain provisions of the federal income tax laws. Those relief provisions are available if:

We cannot predict, however, whether any failure to meet these tests will qualify for the relief provisions. In addition, as discussed above in “— Taxation of Our Company,” even if the relief provisions apply, we would incur a 100% tax on the gross income attributable to the greater of (1) the amount by which we fail the 75% gross income test, or (2) the amount by which we fail the 95% gross income test, multiplied, in either case, by a fraction intended to reflect our profitability.

Asset Tests

To maintain our qualification as a REIT, we also must satisfy the following asset tests at the end of each quarter of each taxable year.

First, at least 75% of the value of our total assets, or the “75% asset test,” must consist of:

37

Table of Contents

Second, of our assets that are not qualifying assets for purposes of the 75% asset test described above, the value of our interest in any one issuer’s securities may not exceed 5% of the value of our total assets, or the “5% asset test.”

Third, of our assets that are not qualifying assets for purposes of the 75% asset test described above, we may not own more than 10% of the voting power of any one issuer’s outstanding securities, or the “10% vote test,” or more than 10% of the value of any one issuer’s outstanding securities, or the “10% value test.”

Fourth, no more than 25% of the value of our total assets may consist of the securities of one or more taxable REIT subsidiaries.

Fifth, no more than 25% of the value of our total assets may consist of the securities of taxable REIT subsidiaries and other taxable subsidiaries and other assets that are not qualifying assets for purposes of the 75% asset test.

For purposes of the 5% asset test, the 10% vote test and the 10% value test, the term “securities” does not include stock in another REIT, equity or debt securities of a qualified REIT subsidiary or taxable REIT subsidiary, mortgage loans that constitute real estate assets, or equity interests in an entity taxed as a partnership. The term “securities,” however, generally includes debt securities issued by an entity taxed as a partnership or another REIT, except that for purposes of the 10% value test, the term “securities” does not include:

38

Table of Contents

For purposes of the 10% value test, our proportionate share of the assets of an entity taxed as a partnership is our proportionate interest in any securities issued by such entity, without regard to the securities described in the preceding two bullet points above.

We believe that the assets that we hold satisfy the foregoing asset test requirements. We will not obtain, however, nor are we required to obtain under the federal income tax laws, independent appraisals to support our conclusions as to the value of our assets and securities or the real estate collateral for the mortgage or mezzanine loans that we may originate or acquire. Moreover, the values of some assets may not be susceptible to a precise determination. As a result, there can be no assurance that the IRS will not contend that our ownership of securities and other assets violates one or more of the asset tests applicable to REITs.

As noted above, we may invest opportunistically in loans secured by interests in real property. If the outstanding principal balance of a loan during a taxable year exceeds the fair market value of the real property securing such loan as of the date we agreed to originate or acquire the loan, a portion of such loan likely will not constitute a qualifying real estate asset for purposes of the 75% asset test. Although the law on the matter is not entirely clear, it appears that the nonqualifying portion of such loan will be equal to the portion of the loan amount that exceeds the value of the associated real property that serves as security for that loan.

Failure to Satisfy Asset Tests. We will monitor the status of our assets for purposes of the various asset tests and will manage our portfolio in order to comply at all times with such tests. Nevertheless, if we fail to satisfy the asset tests at the end of a calendar quarter, we will not lose our REIT status if:

If we did not satisfy the condition described in the second bullet point immediately above, we still could avoid REIT disqualification by eliminating any discrepancy within 30 days after the close of the calendar quarter in which the discrepancy arose.

In the event that we violate the 5% asset test, the 10% vote test or the 10% value test described above, we will not lose our REIT status if (1) the failure is de minimis (up to the lesser of 1% of our assets or $10 million) and (2) we dispose of assets causing the failure or otherwise comply with the asset tests within six months after the last day of the quarter in which we identify such failure. In the event of a failure of any of such asset tests other than a de minimis failure, as described in the preceding sentence, we will not lose our REIT status if (1) the failure was due to reasonable cause and not to willful neglect, (2) we file a description of each asset causing the failure with the IRS, (3) we dispose of assets causing the failure or otherwise comply with the asset tests within six months after the last day of the quarter in which we identify the failure, and (4) we pay a tax equal to the greater of $50,000 or the highest corporate federal income tax rate multiplied by of the net income from the nonqualifying assets during the period in which we failed to satisfy the asset tests.

Annual Distribution Requirements

Each taxable year, we must make distributions, other than capital gain dividend distributions and deemed distributions of retained capital gain, to our stockholders in an aggregate amount at least equal to:

Generally, we must pay such distributions in the taxable year to which they relate, or in the following taxable year if either (1) we declare the distribution before we timely file our federal income tax return for the year and pay the distribution on or before the first regular dividend payment date after such declaration or (2) we declare the distribution in October, November, or December of the taxable year, payable to stockholders of record on a specified day in any such month, and we actually pay the dividend before the end of January of the following year. In both instances, these distributions relate to our prior taxable year for purposes of the annual distribution requirement.

We will pay federal income tax on any taxable income, including net capital gain, that we do not distribute to our stockholders. Furthermore, if we fail to distribute during a calendar year, or by the end of January of the following calendar year in the case of distributions with declaration and record dates falling in the last three months of the calendar year, at least the sum of:

we will incur a 4% nondeductible excise tax on the excess of such required distribution over the amounts we actually distributed.

We may elect to retain and pay federal income tax on the net long-term capital gain that we receive in a taxable year. If we so elect, we will be treated as having distributed any such retained amount for purposes of the 4% nondeductible excise tax described above. We intend to make timely distributions sufficient to satisfy the annual distribution requirement and to minimize corporate income tax and avoid the 4% nondeductible excise tax.

In addition, if we were to recognize “built-in gain” on the disposition of any assets acquired from an entity treated as a C corporation for federal income tax purposes in a transaction in which our basis in the assets was determined by reference to such entity’s tax basis (for instance, if the assets were acquired in a tax-free reorganization), we would be required to distribute at least 90% of the built-in-gain net of the tax we would pay on such gain. “Built-in gain” is the excess of (1) the fair market value of the asset (measured at the time of acquisition) over (2) the basis of the asset (measured at the time of acquisition).

It is possible that, from time to time, we may experience timing differences between the actual receipt of income and actual payment of deductible expenses and the inclusion of that income and deduction of such expenses in arriving at our REIT taxable income. Further, it is possible that, from time to time, we may be allocated a share of net capital gain from a partnership (or an entity taxed as a partnership for federal income tax purposes) in which we own an interest that is attributable to the sale of depreciated property that exceeds our allocable share of cash attributable to that sale. As a result of the foregoing, we may have less cash than is necessary to make distributions to our stockholders that are sufficient to avoid corporate income tax and the 4% nondeductible excise tax imposed on certain undistributed income or even to meet the annual distribution requirement. In such a situation, we may need to borrow funds or issue additional stock or, if possible, pay dividends consisting, in whole or in part, of our stock or debt securities.

40

Table of Contents

In order for distributions to be counted as satisfying the annual distribution requirement applicable to REITs and to provide us with a REIT-level tax deduction, the distributions must not be “preferential dividends.” A distribution is not a preferential dividend if the distribution is (1) pro rata among all outstanding shares within a particular class, and (2) in accordance with the preferences among different classes of stock as set forth in our organizational documents.

Under certain circumstances, we may be able to correct a failure to meet the distribution requirement for a year by paying “deficiency dividends” to our stockholders in a later year. We may include such deficiency dividends in our deduction for dividends paid for the earlier year. Although we may be able to avoid income tax on amounts distributed as deficiency dividends, we will be required to pay interest to the IRS based on the amount of any deduction we take for deficiency dividends.

Recordkeeping Requirements

We must maintain certain records in order to maintain our qualification as a REIT. To avoid paying monetary penalties, we must demand, on an annual basis, information from certain of our stockholders designed to disclose the actual ownership of our outstanding stock, and we must maintain a list of those persons failing or refusing to comply with such demand as part of our records. A stockholder that fails or refuses to comply with such demand is required by the Treasury Regulations to submit a statement with its tax return disclosing the actual ownership of our stock and other information. We intend to comply with these recordkeeping requirements.

Failure to Qualify as a REIT

If we fail to satisfy one or more requirements for REIT qualification, other than the gross income tests and the asset tests, we could avoid disqualification if our failure is due to reasonable cause and not to willful neglect and we pay a penalty of $50,000 for each such failure. In addition, there are relief provisions available under the Code for a failure of the gross income tests and asset tests, as described in “— Gross Income Tests” and “— Asset Tests.”

If we were to fail to maintain our qualification as a REIT in any taxable year, and no relief provision applied, we would be subject to federal income tax on our taxable income at federal corporate income tax rates and any applicable alternative minimum tax. In calculating our taxable income for a year in which we failed to maintain our qualification as a REIT, we would not be able to deduct amounts distributed to our stockholders, and we would not be required to distribute any amounts to our stockholders for that year. In such event, to the extent of our current and accumulated earnings and profits, distributions to our stockholders generally would be taxable to our stockholders as ordinary income. Subject to certain limitations of the federal income tax laws, our corporate stockholders may be eligible for the dividends received deduction, and stockholders taxed at individual rates may be eligible for a maximum federal income tax rate of 20% on such dividends. Unless we qualified for relief under the statutory relief provisions described in the preceding paragraph, we also would be disqualified from taxation as a REIT for the four taxable years following the year during which we ceased to maintain our qualification as a REIT. We cannot predict whether in all circumstances we would qualify for such statutory relief.

Taxation in Connection with Holding Securities other than our Stock

We intend to describe in any prospectus supplement related to the offering of our debt securities, depositary shares or subscription rights, the material federal income tax considerations relating to the ownership and disposition of such securities, including, if applicable, (1) the taxation of any debt securities that will be sold with original issue discount or acquired with market discount or amortizable bond premium and (2) the tax treatment of sales, exchanges or retirements of our debt securities.

Taxation of Taxable U.S. Stockholders

For purposes of our discussion, the term “U.S. stockholder” means a holder of our common stock, senior common stock and preferred stock that, for federal income tax purposes, is:

If a partnership, entity or arrangement taxed as a partnership for federal income tax purposes (a “partnership”) holds our stock, the federal income tax treatment of an owner of the partnership generally will depend on the status of the owner and the activities of the partnership. If you are an owner of a partnership that may acquire our stock, you should consult your tax advisor regarding the tax consequences of the ownership and disposition of our stock by the partnership.

Distributions. As long as we qualify as a REIT, distributions made out of our current or accumulated earnings and profits that we do not designate as capital gain dividends or retained long-term capital gains will be dividend income to taxable U.S. stockholders. In determining the extent to which a distribution with respect to our stock constitutes a dividend for federal income tax purposes, our earnings and profits will be allocated first to distributions with respect to our preferred stock and senior common stock and then to our common stock. A corporate U.S. stockholder will not qualify for the dividends-received deduction generally available to corporations. Dividends paid to a U.S. stockholder generally will not qualify for the tax rates applicable to “qualified dividend income.” Qualified dividend income generally includes dividends paid by domestic C corporations and certain qualified foreign corporations to U.S. stockholders that are taxed at individual rates. Because we are not generally subject to federal income tax on the portion of our REIT taxable income that we distribute to our stockholders, our dividends generally will not constitute qualified dividend income. As a result, our REIT dividends generally will be taxed at the higher tax rates applicable to ordinary income. The highest marginal individual income tax rate on ordinary income is 39.6%. The federal income tax rates applicable to qualified dividend income generally will apply, however, to our ordinary REIT dividends, if any, that are (1) attributable to qualified dividends received by us from non-REIT corporations, such as any taxable REIT subsidiaries, or (2) attributable to income recognized by us and on which we have paid federal corporate income tax (e.g., to the extent that we distribute less than 100% of our taxable income). In general, to qualify for the reduced federal income tax rate on qualified dividend income under such circumstances, a U.S. stockholder must hold our stock for more than 60 days during the 121-day period beginning on the date that is 60 days before the date on which our stock becomes ex-dividend. In addition, a taxable U.S. stockholder that is an individual, an estate or an enumerated trust and that has taxable income in excess of certain thresholds is subject to a 3.8% Medicare tax on dividends received from us.

Any distribution we declare in October, November, or December of any year that is payable to a U.S. stockholder of record on a specified date in any of those months will be treated as paid by us and received by the U.S. stockholder on December 31 of that year to the extent it is a dividend attributable to earnings and profits, provided that we actually pay the distribution during January of the following calendar year.

Distributions to a U.S. stockholder which we designate as capital gain dividends generally will be treated as long-term capital gain, without regard to the period for which the U.S. stockholder has held our stock. See “— Capital Gains and Losses” below. A corporate U.S. stockholder may be required to treat up to 20% of certain capital gain dividends as ordinary income.

42

Table of Contents

We may elect to retain and pay federal corporate income tax on the net long-term capital gain that we receive in a taxable year. In that case, to the extent that we designate such amount in a timely notice to our stockholders, a U.S. stockholder would be taxed on its proportionate share of our undistributed long-term capital gain. The U.S. stockholder would receive a credit or refund for its proportionate share of the federal corporate income tax we paid, however, the U.S. stockholder would increase its basis in our stock by the amount of its proportionate share of our undistributed long-term capital gain, minus its share of the federal corporate income tax we paid.

A U.S. stockholder will not incur federal income tax on a distribution in excess of our current and accumulated earnings and profits if the distribution does not exceed the U.S. stockholder’s adjusted basis in our stock. Instead, the distribution will reduce the U.S. stockholder’s adjusted basis in our stock, and any amount in excess of both its share of our current and accumulated earnings and profits and its adjusted basis will be treated as capital gain, long-term if the stock has been held for more than one year, provided the stock is a capital asset in the hands of the U.S. stockholder.

U.S. stockholders may not include in their individual federal income tax returns any of our net operating losses or capital losses. Instead, these losses are generally carried over by us for potential offset against our future income. Taxable distributions from us and gain from the disposition of our stock will not be treated as passive activity income, and, therefore, U.S. stockholders generally will not be able to apply any “passive activity losses,” such as, for example, losses from certain types of entities in which the U.S. stockholder is treated as a limited partner for federal income tax purposes, against such income. In addition, taxable distributions from us and gain from the disposition of our stock generally will be treated as investment income for purposes of the investment interest limitations. We will notify U.S. stockholders after the close of our taxable year as to the portions of the distributions attributable to that taxable year that constitute ordinary income, return of capital and capital gain.

Dispositions. A U.S. stockholder who is not a dealer in securities generally must treat any gain or loss realized on a taxable disposition of our stock as long-term capital gain or loss if the U.S. stockholder has held such stock for more than one year, and otherwise as short-term capital gain or loss. In general, a U.S. stockholder will realize gain or loss in an amount equal to the difference between (1) the sum of the fair market value of any property and the amount of cash received in such disposition and (2) the U.S. stockholder’s adjusted tax basis in such stock. A U.S. stockholder’s adjusted tax basis in our stock generally will equal the U.S. stockholder’s acquisition cost, increased by the excess of undistributed net capital gains deemed distributed to the U.S. stockholder over the federal corporate income tax deemed paid by the U.S. stockholder on such gains and reduced by any returns of capital. However, a U.S. stockholder must treat any loss on a sale or exchange of our stock held by such stockholder for six months or less as a long-term capital loss to the extent of capital gain dividends and any other actual or deemed distributions from us that such U.S. stockholder treats as long-term capital gain. All or a portion of any loss that a U.S. stockholder realizes on a taxable disposition of shares of our stock may be disallowed if the U.S. stockholder purchases other shares of our stock within 30 days before or after the disposition. In addition, a taxable U.S. stockholder that is an individual, an estate or a enumerated trust and that has taxable income in excess of certain thresholds generally is subject to a 3.8% Medicare tax on gain from the sale of our stock.

Capital Gains and Losses. The federal income tax-rate differential between long-term capital gain and ordinary income for non-corporate taxpayers may be significant. A taxpayer generally must hold a capital asset for more than one year for gain or loss derived from its sale or exchange to be treated as long-term capital gain or loss. The maximum federal income tax rate on ordinary gain applicable to U.S. stockholders that are taxed at individual rates, currently is 39.6%, and the maximum federal income tax rate on long-term capital gain applicable to U.S. stockholders that are taxed at individual rates currently is 20%. The maximum tax rate on long-term capital gain from the sale or exchange of “section 1250 property” (i.e., generally, depreciable real property) is 25% to the extent the gain would have been treated as ordinary income if the property were “section 1245 property” (i.e., generally, depreciable personal property). We generally will designate whether a

43

Table of Contents

distribution that we designate as capital gain dividends (and any retained capital gain that we are deemed to distribute) is attributable to the sale or exchange of “section 1250 property.” The characterization of income as capital gain or ordinary income may affect the deductibility of capital losses. A non-corporate taxpayer may deduct capital losses not offset by capital gains against its ordinary income only up to a maximum annual amount of $3,000. A non-corporate taxpayer may carry forward unused capital losses indefinitely. A corporate taxpayer must pay tax on its net capital gain at federal corporate income tax rates, whether or not such gains are classified as long-term capital gains. A corporate taxpayer may deduct capital losses only to the extent of capital gains, with unused losses carried back three years and forward five years.

Taxation of Tax-Exempt Stockholders

Tax-exempt entities, including qualified employee pension and profit sharing trusts and individual retirement accounts and annuities, generally are exempt from federal income taxation. However, they are subject to taxation on their “unrelated business taxable income,” or UBTI. Amounts that we distribute to tax-exempt stockholders generally should not constitute UBTI. If a tax-exempt stockholder were to finance its acquisition of our stock with debt, however, a portion of the distribution that it received from us would constitute UBTI pursuant to the “debt-financed property” rules. Furthermore, social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, and qualified group legal services plans that are exempt from taxation under special provisions of the federal income tax laws are subject to different UBTI rules, which generally will require them to characterize distributions that they receive from us as UBTI.

Finally, in certain circumstances, a qualified employee pension or profit-sharing trust that owns more than 10% of the value of our stock must treat a percentage of the dividends that it receives from us as UBTI. Such percentage is equal to the gross income that we derive from unrelated trades or businesses, determined as if we were a pension trust, divided by our total gross income for the year in which we pay the dividends. Such rule applies to a pension trust holding more than 10% of the value of our stock only if:

We will be classified as a “pension-held REIT” if:

As a result of limitations included in our charter on the transfer and ownership of our stock, we do not expect to be classified as a “pension-held REIT,” and, therefore, the tax treatment described in this paragraph should be inapplicable to our stockholders. However, because certain classes of our stock are publicly traded, we cannot guarantee that this will always be the case.

Taxation of Non-U.S. Stockholders

For purposes of our discussion, the term “non-U.S. stockholder” means a holder of our stock that is not a U.S. stockholder, an entity or arrangement taxed as a partnership for U.S. federal income tax purposes or a tax-

44

Table of Contents

exempt stockholder. Special rules may apply to non-U.S. stockholders that are subject to special treatment under the Code, including controlled foreign corporations, passive foreign investment companies, U.S. expatriates and foreign persons eligible for benefits under an applicable income tax treaty with the United States.

We urge non-U.S. stockholders to consult their own tax advisors to determine the impact of federal, state, local and foreign income tax laws on the acquisition, ownership and disposition of our stock, including any reporting requirements.

Distributions. A non-U.S. stockholder that receives a distribution that is not attributable to gain from our sale or exchange of a “United States real property interest,” or a USRPI (discussed below), and that we do not designate as a capital gain dividend or retained long-term capital gain will recognize ordinary income to the extent that we pay such distribution out of our current and accumulated earnings and profits. A withholding tax equal to 30% of the gross amount of the distribution ordinarily will apply unless an applicable tax treaty reduces or eliminates the tax. A non-U.S. stockholder generally will be subject to federal income tax at graduated rates, however, on any distribution treated as effectively connected with the non-U.S. stockholder’s conduct of a U.S. trade or business, in the same manner as U.S. stockholders are taxed on distributions. A corporate non-U.S. stockholder may, in addition, be subject to the 30% branch profits tax with respect to any such distribution. We plan to withhold federal income tax at the rate of 30% on the gross amount of any distribution paid to a non-U.S. stockholder unless either:

A non-U.S. stockholder will not incur tax on a distribution in excess of our current and accumulated earnings and profits if the excess portion of such distribution does not exceed such non-U.S. stockholder’s adjusted basis in our stock. Instead, the excess portion of such distribution will reduce the non-U.S. stockholder’s adjusted basis in our stock. A non-U.S. stockholder will be subject to tax on a distribution that exceeds both our current and accumulated earnings and profits and the non-U.S. stockholder’s adjusted basis in our stock, if the non-U.S. stockholder otherwise would be subject to tax on gain from the sale or disposition of our stock, as described below. See “— Dispositions” below. Under FIRPTA (discussed below), we may be required to withhold 10% of any distribution that exceeds our current and accumulated earnings and profits. Although we intend to withhold at a rate of 30% on the entire amount of any distribution (other than a distribution attributable to a sale of a USRPI), to the extent that we do not do so, we may withhold at a rate of 10% on any portion of a distribution not subject to withholding at a rate of 30%. Because we generally cannot determine at the time we make a distribution whether the distribution will exceed our current and accumulated earnings and profits, we may withhold tax on the entire amount of any distribution. However, a non-U.S. stockholder may obtain a refund of amounts that we withhold if we later determine that a distribution in fact exceeded our current and accumulated earnings and profits.

For any year in which we maintain our qualification as a REIT, the Foreign Investment in Real Property Tax Act of 1980, or FIRPTA, may apply to our sale or exchange of a USRPI. A USRPI includes certain interests in real property and stock in corporations at least 50% of whose assets consist of interests in real property. Under FIRPTA, a non-U.S. stockholder is taxed on distributions attributable to gain from sales of USRPIs as if such gain were effectively connected with the conduct of a U.S. trade or business of the non-U.S. stockholder. A non-U.S. stockholder thus would be taxed on such a distribution at the normal capital gains rates applicable to U.S. stockholders, subject to applicable alternative minimum tax and a special alternative minimum tax in the case of a nonresident alien individual. A non-U.S. corporate stockholder not entitled to treaty relief or exemption also may be subject to the 30% branch profits tax on such a distribution.

45

Table of Contents

If a class of our stock is regularly traded on an established securities market in the United States (any such class of our stock referred to as a “publicly traded class”), capital gain distributions to a non-U.S. stockholder in respect of stock of such publicly traded class that is attributable to our sale of real property will be treated as ordinary dividends rather than as gain from the sale of a USRPI, as long as such non-U.S. stockholder did not own more than 5% of the outstanding stock of such publicly traded class at any time during the one-year period preceding the distribution. As a result, non-U.S. stockholders owning 5% or less of the outstanding stock of such publicly traded class generally would be subject to withholding tax on such capital gain distributions in the same manner as they are subject to withholding tax on other distributions. If a non-U.S. stockholder owned more than 5% of the outstanding stock of a publicly traded class at any time during the one-year period preceding the distribution, capital gain distributions to such non-U.S. stockholder in respect of the stock of such publicly traded class that are attributable to our sale of USRPIs would be subject to tax under FIRPTA, as described above. Additionally, capital gain distributions to a non-U.S. stockholder in respect of stock of a class that is not a publicly traded class that are attributable to our sale of real property would be subject to tax under FIRPTA, as described above.

If a distribution is subject to FIRPTA, we must withhold 35% of such distribution that we could designate as a capital gain dividend. A non-U.S. stockholder may receive a credit against its tax liability for the amount that we withhold. Moreover, if a non-U.S. stockholder disposes of our stock during the 30-day period preceding a dividend payment, and such non-U.S. stockholder (or a person related to such non-U.S. stockholder) acquires or enters into a contract or option to acquire our stock within 61 days of the first day of the 30-day period described above, and any portion of such dividend payment would, but for the disposition, be treated as a USRPI capital gain to such non-U.S. stockholder, then such non-U.S. stockholder will be treated as having USRPI capital gain in an amount that, but for the disposition, would have been treated as USRPI capital gain.

Dispositions. Non-U.S. stockholders may incur tax under FIRPTA with respect to gain realized on a disposition of our stock since our stock will constitute a USRPI unless one of the applicable exceptions, as described below, applies. Any gain subject to tax under FIRPTA will be treated in the same manner as it would be in the hands of U.S. stockholders subject to alternative minimum tax, but under a special alternative minimum tax in the case of nonresident alien individuals.

Non-U.S. stockholders generally will not incur tax under FIRPTA with respect to gain on a sale of our stock, however, as long as, at all times, we are domestically controlled, i.e., non-U.S. persons hold, directly or indirectly, less than 50% in value of our outstanding stock. We cannot assure you that we will be domestically controlled. In addition, even if we are not domestically controlled, a non-U.S. stockholder that owned, actually or constructively, 5% or less of the outstanding stock of a publicly traded class at all times during a specified testing period will not incur tax under FIRPTA on gain from a sale of such stock.

Even if stock of a non-publicly traded class would otherwise constitute a USRPI, gain arising from the sale or other taxable disposition of such stock by a non-U.S. stockholder will not be subject to tax under FIRPTA as a sale of a USRPI if we have a publicly traded class and the applicable non-U.S. stockholder has not, at the time it acquires the stock of a non-publicly traded class, and at certain other times described in the applicable Treasury Regulations, directly or indirectly held stock of a non-publicly traded class (and in certain cases other direct or indirect interests in our stock) that had a fair market value in excess of 5% of the fair market value of our publicly traded class with the lowest fair market value. In addition, stock of a non-publicly traded class that is convertible into a stock of a publicly traded class and that is owned by a non-U.S. stockholder would not be considered a USRPI if, on the acquisition date, such stock had a fair market value that did not exceed the fair market value on such date of 5% of the total outstanding stock of the publicly traded class into which the stock of the non-publicly traded class is convertible.

Information Reporting Requirements, Backup Withholding and Certain Other Required Withholding

We will report to our stockholders and to the IRS the amount of distributions that we pay during each calendar year, and the amount of tax that we withhold, if any. Under the backup withholding rules, a stockholder may be subject to backup withholding (at a rate of 28%) with respect to distributions unless the stockholder:

A stockholder who does not provide us with its correct taxpayer identification number also may be subject to penalties imposed by the IRS. Any amount paid as backup withholding will be creditable against the stockholder’s federal income tax liability. In addition, we may be required to withhold a portion of capital gain distributions to any stockholders who fail to certify their non-foreign status to us.

Backup withholding generally will not apply to payments of dividends made by us or our paying agents, in their capacities as such, to a non-U.S. stockholder provided that such non-U.S. stockholder furnishes to us or our paying agent the required certification as to its non-U.S. status, such as providing a valid IRS Form W-8BEN or W-8ECI, or certain other requirements are met. Notwithstanding the foregoing, backup withholding may apply if either we or our paying agent has actual knowledge, or reason to know, that the holder is a “U.S. person” that is not an exempt recipient. Payments of the proceeds from a disposition or a redemption of our stock that occurs outside the U.S. by a non-U.S. stockholder made by or through a foreign office of a broker generally will not be subject to information reporting or backup withholding. However, information reporting (but not backup withholding) generally will apply to such a payment if the broker has certain connections with the U.S. unless the broker has documentary evidence in its records that demonstrates that the beneficial owner is a non-U.S. stockholder and specified conditions are met or an exemption is otherwise established. Payment of the proceeds from a disposition of our stock by a non-U.S. stockholder made by or through the U.S. office of a broker generally is subject to information reporting and backup withholding unless the non-U.S. stockholder certifies under penalties of perjury that it is not a U.S. person and satisfies certain other requirements, or otherwise establishes an exemption from information reporting and backup withholding.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or credited against the stockholder’s federal income tax liability if certain required information is furnished to the IRS. Stockholders should consult their own tax advisors regarding application of backup withholding to them and the availability of, and procedure for obtaining an exemption from, backup withholding.

The Foreign Account Tax Compliance Act (“FATCA”) imposes a 30% withholding tax on certain types of payments made to “foreign financial institutions” and certain other non-U.S. entities unless certain due diligence, reporting, withholding, and certification obligation requirements are satisfied. The U.S. Treasury Department and the IRS recently issued final Treasury Regulations under FATCA. FATCA generally imposes a 30% withholding

tax on dividends on, and gross proceeds from the sale or other disposition of, our stock if paid to a foreign entity unless either (i) the foreign entity is a “foreign financial institution” that undertakes certain due diligence, reporting, withholding, and certification obligations, or in the case of a foreign financial institution that is a resident in a jurisdiction that has entered into an intergovernmental agreement to implement FATCA, the entity complies with the diligence and reporting requirements of such agreement, (ii) the foreign entity is not a “foreign financial institution” and identifies certain of its U.S. investors, or (iii) the foreign entity otherwise is excepted under FATCA. Under delayed effective dates provided for in the Treasury Regulations and other IRS guidance, such required withholding would not begin until July 1, 2014 with respect to dividends on our stock, and January 1, 2017 with respect to gross proceeds from a sale or other disposition of our stock.

If withholding is required under FATCA on a payment related to our stock, holders of our stock that otherwise would not be subject to withholding (or that otherwise would be entitled to a reduced rate of withholding) generally will be required to seek a refund or credit from the IRS to obtain the benefit of such exemption or reduction (provided that such benefit is available). You should consult your own tax advisor regarding the effect of FATCA on an investment in our stock.

Tax Aspects of Our Investments in Our Operating Partnership and Subsidiary Partnerships.

We currently hold, directly and indirectly, all of the ownership interests in our Operating Partnership and our other subsidiaries; therefore, our Operating Partnership and our other subsidiaries (other than any taxable REIT subsidiaries) currently are disregarded for federal income tax purposes. See “—Requirements for Qualification as a REIT – Qualified REIT Subsidiaries” and “—Requirements for Qualification as a REIT – Other Disregarded Entities and Partnerships” above. If additional partners or members are admitted to our Operating Partnership or any of our other subsidiaries, as applicable, we intend for such entity to be taxed as a partnership for federal income tax purposes. The following discussion summarizes certain federal income tax considerations that would be applicable if our Operating Partnership or other subsidiaries were taxed as partnerships for federal income tax purposes, each individually referred to as a “Partnership” and, collectively, as the “Partnerships.” The following discussion does not address state or local tax laws or any federal tax laws other than income tax laws.

Classification as Partnerships

We are required to include in our income our distributive share of each Partnership’s income and to deduct our distributive share of each Partnership’s losses but only if such Partnership is classified for federal income tax purposes as a partnership, rather than as a corporation or an association taxable as a corporation. An unincorporated entity with at least two owners or members, as determined for federal income tax purposes, will be classified as a partnership, rather than as a corporation, for federal income tax purposes if it:

Under the check-the-box regulations, an unincorporated entity with at least two owners or members may elect to be classified either as an association taxable as a corporation or as a partnership. If such an entity does not make an election, it generally will be taxed as a partnership for federal income tax purposes.

A publicly traded partnership is a partnership whose interests are traded on an established securities market or are readily tradable on a secondary market or the substantial equivalent thereof. A publicly traded partnership generally is treated as a corporation for federal income tax purposes, but will not be so treated if, for each taxable year beginning after December 31, 1987 in which it was classified as a publicly traded partnership, at least 90% of the partnership’s gross income consisted of specified passive income, including real property rents, gains from the sale or other disposition of real property, interest, and dividends, or the “90% passive income exception.” The

48

Table of Contents

Treasury Regulations provide limited safe harbors from treatment as a publicly traded partnership. Pursuant to one of those safe harbors, interests in a partnership will not be treated as readily tradable on a secondary market or the substantial equivalent thereof if (1) all interests in the partnership were issued in a transaction or transactions that were not required to be registered under the Securities Act of 1933, as amended, and (2) the partnership does not have more than 100 partners at any time during the partnership’s taxable year. In determining the number of partners in a partnership, a person owning an interest in a partnership, grantor trust, or S corporation that owns an interest in the partnership is treated as a partner in such partnership only if (1) substantially all of the value of the owner’s interest in the entity is attributable to the entity’s direct or indirect interest in the partnership and (2) a principal purpose of the use of the entity is to permit the partnership to satisfy the 100-partner limitation. If any Partnership does not qualify for any safe harbor and is treated as a publicly traded partnership, we believe that such Partnership would have sufficient qualifying income to satisfy the 90% passive income exception and, therefore, would not be treated as a corporation for federal income tax purposes.

We have not requested, and do not intend to request, a ruling from the IRS that any of our direct or indirect subsidiaries is or will be classified as a partnership for federal income tax purposes. If, for any reason, a Partnership were taxable as a corporation, rather than as a partnership, for federal income tax purposes, we may not be able to maintain our qualification as a REIT, unless we qualify for certain statutory relief provisions. See “— Gross Income Tests” and “— Asset Tests.” In addition, any change in a Partnership’s status for tax purposes might be treated as a taxable event, in which case we might incur tax liability without any related cash distribution. See “— Annual Distribution Requirements.” Further, items of income and deduction of such Partnership would not pass through to us, and we would be treated as a stockholder for federal income tax purposes. Consequently, such Partnership would be required to pay income tax at corporate rates on its net income, and distributions to us would constitute dividends that would not be deductible in computing such Partnership’s taxable income.

Income Taxation of the Partnerships and Their Partners

Partners, Not the Partnerships, Subject to Tax. A Partnership is not a taxable entity for federal income tax purposes. Rather, we are required to take into account our distributive share of each Partnership’s income, gains, losses, deductions, and credits for each taxable year of the Partnership ending with or within our taxable year, even if we receive no distribution from the Partnership for that year or a distribution that is less than our share of taxable income. Similarly, even if we receive a distribution, it may not be taxable if the distribution does not exceed our adjusted tax basis in our interest in the Partnership.

Partnership Allocations. Although an agreement among the owners of an entity taxed as a partnership for federal income tax purposes generally will determine the allocation of income and losses among the owners, such allocations will be disregarded for tax purposes if they do not comply with the provisions of the federal income tax laws governing partnership allocations. If an allocation is not recognized for federal income tax purposes, the item subject to the allocation will be reallocated in accordance with the “partners’ interests in the partnership,” which will be determined by taking into account all of the facts and circumstances relating to the economic arrangement of the owners with respect to such item.

Tax Allocations With Respect to Contributed Properties. Income, gain, loss, and deduction attributable to appreciated or depreciated property that is contributed to an entity taxed as a partnership for federal income tax purposes in exchange for an interest in such entity must be allocated for federal income tax purposes in a manner such that the contributing owner is charged with, or benefits from, respectively, the unrealized gain or unrealized loss associated with the property at the time of the contribution (the “704(c) Allocations”). The amount of such unrealized gain or unrealized loss, referred to as “built-in gain” or “built-in loss,” at the time of contribution 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 that time, referred to as a book-tax difference. A book-tax difference attributable to depreciable property generally is decreased on an annual basis as a result of the allocation of depreciation deductions to the contributing owner for book purposes, but not for tax purposes. The

49

Table of Contents

704(c) Allocations are solely for federal income tax purposes and do not affect the book capital accounts or other economic or legal arrangements among the owners. The Treasury Regulations require entities taxed as a partnership for federal income tax purposes to use a “reasonable method” for allocating items with respect to which there is a book-tax difference and outline several reasonable allocation methods.

If our Operating Partnership were to admit additional partners and therefore be taxed as a partnership for federal income tax purposes, the properties owned by the Operating Partnership would be deemed to have been contributed to a partnership for federal income tax purposes, which could result in future 704(c) Allocations to us. In addition, the carryover basis of any properties actually contributed to our Operating Partnership by an additional partner, under certain reasonable methods available to us, including the “traditional method,” (1) would cause us to be allocated lower amounts of depreciation deductions for tax purposes than would be allocated to us if all contributed properties were to have a tax basis equal to their fair market value at the time of the contribution and (2) in the event of a sale of such properties, could cause us to be allocated taxable gain in excess of the economic or book gain allocated to us as a result of such sale, with a corresponding tax benefit to the contributing partners. An allocation described in clause (2) of the immediately preceding sentence may cause us to recognize taxable income in excess of cash proceeds in the event of a sale or other disposition of property, which might adversely affect our ability to comply with the REIT distribution requirements and may result in a greater portion of our distributions being taxed as dividends.

Basis in Partnership Interest. Our adjusted tax basis in any Partnership interest we own generally will be:

Loss allocated to us in excess of our basis in a Partnership interest will not be taken into account for federal income tax purposes until we again have basis sufficient to absorb the loss. A reduction of our allocable share of indebtedness of the Partnership will be treated as a constructive cash distribution to us, and will reduce our adjusted tax basis in the Partnership interest. Distributions, including constructive distributions, in excess of the basis of our partnership interest will constitute taxable income to us. Such distributions and constructive distributions normally will be characterized as long-term capital gain.

Sale of a Partnership’s Property. Generally, any gain realized by a Partnership on the sale of property held for more than one year will be long-term capital gain, except for any portion of the gain treated as depreciation or cost recovery recapture. Our share of any Partnership’s gain from the sale of inventory or other property held primarily for sale to customers in the ordinary course of the Partnership’s trade or business will be treated as income from a prohibited transaction subject to a 100% tax. Income from a prohibited transaction may have an adverse effect on our ability to satisfy the gross income tests for REIT status. See “— Gross Income Tests.” We presently do not intend to acquire or hold, or to allow any Partnership to acquire or hold, any property that is likely to be treated as inventory or property held primarily for sale to customers in the ordinary course of our, or any Partnership’s, trade or business.

State and Local Taxes

We and/or you may be subject to taxation by various states and localities, including those in which we or a stockholder transacts business, owns property or resides. The state and local tax treatment may differ from the federal income tax treatment described above. Consequently, you should consult your own tax advisors regarding the effect of state and local tax laws on an investment in our securities.

Sales Through Underwriters

If underwriters are used in the sale, they will acquire the securities for their own account and may resell them from time to time in one or more transactions at a fixed public offering price. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Subject to certain conditions, the underwriters will be obligated to purchase all of the securities of the series offered by the prospectus supplement. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may change from time to time. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

Sales Through Agents

We may sell securities directly or through agents that we designate from time to time. We will name any agent involved in the offering and sale of securities, and we will describe any commissions that we will pay the agent in the prospectus supplement. Unless the prospectus supplement states otherwise, our agent will act on a best-efforts basis for the period of its appointment.

Securities bought in accordance with a redemption or repayment under their terms also may be offered and sold, if so indicated in the accompanying prospectus supplement, in connection with a remarketing by one or more firms acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified, and the terms of its agreement, if any, with us and its compensation will be described in the prospectus supplement. Remarketing firms may be deemed to be underwriters in connection with the securities remarketed by them. If so indicated in the applicable prospectus supplement, we may authorize agents, underwriters or dealers to solicit offers by certain specified institutions to purchase securities at a price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a future date specified in the prospectus supplement. These contracts will be subject only to those conditions set forth in the accompanying prospectus supplement, and the prospectus supplement will set forth the commissions payable for solicitation of these contracts.

Direct Sales

We may authorize agents or underwriters to solicit offers by certain types of institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions that we must pay for solicitation of these contracts in the prospectus supplement.

General Information

We will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, if we enter into any material arrangement with a broker, dealer, agent or underwriter for the sale of securities through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer. Such prospectus supplement will disclose:

Our common stock trades on the NASDAQ Global Select Market under the symbol “GOOD.” Our 7.75% Series A Cumulative Redeemable Preferred Stock trades on the NASDAQ Global Select Market under the symbol “GOODP,” our 7.50% Series B Cumulative Redeemable Preferred Stock trades on the NASDAQ Global Select Market under the symbol “GOODO” and our 7.125% Series C Cumulative Term Preferred Stock trades on the NASDAQ Global Select Market under the symbol “GOODN.” Our Senior Common Stock is not listed on an exchange. All securities that we offer, other than our Listed Common Stock or Senior Common Stock, and other than securities issued upon a reopening of a previous series, will be new issues of securities with no established trading market. Any underwriters may make a market in these securities but will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of the trading market for any securities sold by us.

Any underwriter may engage in over-allotment, stabilizing transactions, short covering transactions and penalty bids in accordance with Regulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum price. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

Any underwriters who are qualified market makers on the NASDAQ Global Select Market may engage in passive market making transactions in the securities on the NASDAQ Global Select Market in accordance with Rule 103 of Regulation M under the Exchange Act during the business day prior to the pricing of the offering and before the commencement of offers or sales of the securities. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

Some of the underwriters, dealers and agents and their affiliates may engage in transactions with or perform services for us and our affiliates in the ordinary course of business. Underwriters have from time to time in the past provided, and may from time to time in the future provide, investment banking services to us for which they have in the past received, and in the future may receive, customary fees.
